Subject: [PATCH 001/155] feat(session-projection-cache): store one
 projection_cache.json per session
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the single global session_projcache domain with a per-session
cache file inside the session's own persistence directory, resolved
through sessionPersistence.locate(meta) — the persistence backend owns
the session-directory layout, the cache service keeps every checkpoint
and cold-read responsibility.

- cachedSnapshot(meta) becomes async (one file read per session);
  coldSnapshot takes the session header so it can locate the file, with
  the stored log header remaining the identity witness.
- Backends without a per-session directory (sqlite) disable the durable
  cache: writes no-op and cold reads fall to the full-log rung. An
  obsolete global cache is never read — derived data refolds on first
  cold read (no migration).
- writeAtomic is exported from dsh-storage-json as the shared atomic
  whole-file replace primitive; api-proxy listing and subagent cold
  reads await the now-async cachedSnapshot.
- READMEs and a new Agent Note document the per-session medium.

+# Agent Note: Projection cache as per-session files
+
+Status: implemented
+
+English | [中文](2026-08-19-projection-cache-per-session-files.zh.md)
+
+## Problem
+
+The persisted projection cache was one global `session_projcache.json` — a `sessions` table in a single file at the storage root. Every throttled checkpoint rewrote the whole file containing every session's rows, so write amplification grew with session count, and one malformed file took the entire cache down at once.
+
+## Decision
+
+The cache becomes one `projection_cache.json` per session, stored inside the session's own persistence directory. The location comes from the persistence seam — `sessionPersistence.locate(meta)` — so the persistence backend owns the session-directory layout (the jsonl backend places the file beside the session log); the cache service never imports a backend's path helpers. The cache service keeps every other responsibility: checkpoint fold, write policy (turn/end + disposal mandatory, count/interval throttle), fail-soft durability, and the cold-read ladder.
+
+Reading a cache row is now one file read, so `cachedSnapshot(meta)` is async; `coldSnapshot` takes the session header (it needs the header to locate the file — the stored log's header remains the identity witness). A persistence backend without a per-session directory (e.g. sqlite) disables the durable cache: writes no-op and cold reads fall to the full-log rung.
+
+## Consequences
+
+- Per-session write isolation: each throttled write replaces only that session's small file, removing the global write amplification.
+- Listing pays N small file reads instead of one big load; a session without a cache file simply lacks the projection column.
+- No migration: the cache is derived data, never an authority. An obsolete global cache (or any earlier format) is never read — the first cold read refolds from the log and writes the current format.
+- The cache file is bound to the same log lifecycle as before: the stored `{createdAt, cwd}` identity guards against a recreated id or a swapped store.
+
+## Alternatives considered
+
+- **Keep the global sessions table.** Preserves one-load listing and a synchronous `cachedSnapshot`, but keeps the global write amplification and single-file blast radius that motivated the change.
+- **One storage-domain unit per session in the storage root** (flat `session_projcache_<id>.json`). Rejected: unit names must match `[a-z0-9_]` (session ids cannot), and the files would sit outside the session's own directory, scattering the storage root instead of living beside the log.
+- **Replicate the session-directory layout inside the cache.** Rejected: the persistence backend already owns that layout through `locate`; duplicating the path helpers couples the cache to a backend's internals.

+# Agent Note：投影缓存改为每会话文件
+
+Status: implemented
+
+[English](2026-08-19-projection-cache-per-session-files.md) | 中文
+
+## Problem
+
+持久投影缓存曾是单个全局 `session_projcache.json`——存储根目录下一个文件里的 `sessions` 表。每次节流检查点都会重写包含所有会话行的整个文件，写放大随会话数量增长；且一个畸形文件会让整个缓存一起失效。
+
+## Decision
+
+缓存改为每会话一个 `projection_cache.json`，存放在该会话自己的持久化目录内。位置来自持久化 seam——`sessionPersistence.locate(meta)`——因此会话目录布局由持久化后端所有（jsonl 后端将其放在会话日志旁）；缓存服务绝不 import 后端的路径 helper。缓存服务保留其余全部职责：检查点折叠、写策略（turn/end + dispose 强制点、count/interval 节流）、fail-soft 持久化与冷读阶梯。
+
+读取缓存行现在是一次文件读取，因此 `cachedSnapshot(meta)` 变为异步；`coldSnapshot` 改为接收会话 header（定位文件需要 header——存储日志的 header 仍是身份见证）。没有每会话目录的持久化后端（如 sqlite）会禁用持久缓存：写入变为 no-op，冷读落到全量日志那一级。
+
+## Consequences
+
+- 每会话写入隔离：每次节流写入只替换该会话的小文件，消除全局写放大。
+- 列表读取从一次大加载变为 N 次小文件读取；没有缓存文件的会话只是缺少投影列。
+- 无需迁移：缓存是派生数据，绝非权威。过时的全局缓存（或任何更早格式）从不被读取——首次冷读从日志重折叠并写出当前格式。
+- 缓存文件仍绑定同一日志生命周期：存储的 `{createdAt, cwd}` 身份防止被重建的 id 或替换的存储误导。
+
+## Alternatives considered
+
+- **保留全局 sessions 表。** 保留一次加载式列表与同步 `cachedSnapshot`，但保留了促成此改动的全局写放大与单文件爆炸半径。
+- **存储根目录下每会话一个 storage-domain unit**（扁平 `session_projcache_<id>.json`）。未采用：unit 名必须匹配 `[a-z0-9_]`（会话 id 做不到），且文件会落在会话目录之外，散落在存储根目录而不是日志旁。
+- **在缓存内复刻会话目录布局。** 未采用：持久化后端已通过 `locate` 拥有该布局；复刻路径 helper 会把缓存耦合到后端的内部实现。

-The persisted projection cache (`ctx.sessionProjectionCache`): durable checkpoints of every projection unit's state, one record per session on the domain data form (`session_projcache` domain — the shipped json backend lands it beside `workspace.json` under the configured storage root).

 A stored row `(key → {ver, seq, val})` is a fold shortcut, never an authority: possibly stale (`seq` says exactly how stale) but never wrong. Consequences the implementation commits to:
 
 - **Every background write is fail-soft.** A failed durable write logs a warning and keeps the cache stale; the next write or cold read self-heals. A crash between writes costs a longer tail replay, never a wrong value.
 - **A `ver` mismatch against the live unit's `stateVersion` discards, never migrates.** A unit bump invalidates its rows at read time; the key refolds from the log.
-- **A row must pass the live unit's `stateSchema`.** A malformed row is omitted from the zero-I/O view and rejected by restore so the cold-read ladder refolds it from the log.
-- **Whole-record writes.** Each write replaces the session's full checkpoint (the registry cut is always complete), snapshotted through the lossless-JSON boundary — a unit state violating the plain-JSON contract fails loud.
-- **Records are bound to a log lifecycle, not just an id.** Each record stores the header identity (`createdAt`, `cwd`) it was folded from; every read validates it (the live or stored header is the witness) before accepting a row, so a deleted-then-recreated id or a persistence store swapped under a surviving cache discards the unrelated record instead of seeding phantom values.
-- **The log leads, the cache follows.** A live checkpoint flushes the session's buffered events durably BEFORE the cache row lands, so a crash can leave the cache behind the log (a longer tail replay) but never ahead of it.
+- **A row must pass the live unit's `stateSchema`.** A malformed row is omitted from the cached view and rejected by restore so the cold-read ladder refolds it from the log.

The anchor makes a shrunk log (crash-repair truncation) provable: an overreaching row triggers exactly one full re-read from seq 0 instead of serving a ghost value. No registered units serve `{asOfSeq: -1, values: {}}` without touching persistence; a session with no persisted log rejects with the seam's `not found`.

 - **`ver` 与当前运行单元的 `stateVersion` 不匹配即丢弃，绝不迁移。** 单元递增版本会在读取时使其行失效；该 key 从日志重新折叠。
-- **存储行必须通过当前单元的 `stateSchema`。** 畸形行从零 I/O view 中省略，并被 restore 拒绝，使冷读阶梯从日志重新折叠。
-- **整记录写入。** 每次写入替换该会话的完整检查点（注册表切面始终是完整的），并经无损 JSON 边界快照——违反纯 JSON 约定的单元状态会显式失败并报错。

+- **每会话文件，无全局介质。** 没有每会话目录的持久化后端（如 sqlite）会禁用持久缓存：写入变为 no-op，冷读落到全量日志那一级。过时的缓存（任何更早格式）从不被读取——首次冷读从日志重折叠并写出当前格式。

- Write through @deepseek-ai/dsh-atomic-write with { mode: 0o600,
  dirMode: 0o700 } instead of exporting a second atomic-write primitive
  from dsh-storage-json; the session tree stays owner-only like the jsonl
  backend's own directories.
- Serialize atomic replacements per cache path so an older cut can never
  overwrite a newer one; track in-flight writes and drain them on
  disposal so a late flush cannot land after teardown.
- Detect the absent per-session directory before the checkpoint cut and
  durability flush: sqlite-style backends no-op the write entirely.
- Cold-read write-back path and identity both come from the stored log
  header (tail.meta), so a stale caller header cannot mint an orphan
  cache file.
- Add no-path coverage (write no-op, cachedSnapshot undefined, cold
  fallback to the full-log rung) and a concurrent-write ordering test;
  the package now holds 100% statement/branch/function/line coverage.
- Sync README.md/zh (inject list, coldSnapshot signature, per-session
  file read wording), package description, the Agent Note alternatives,
  and the superseded proposed/implemented notes (EN/ZH); add the
  concurrent-checkpoint Known Limitation.

 - The activity timestamp never reads a log: a live session uses its last in-memory event time; a persisted session stats the artifact named by the optional `sessionPersistence.locate()` (mtime), falling back to the header's creation time when the backend locates no per-session artifact (SQLite) or the stat fails. Any append moves the mtime, so a mere pickup boundary now floats a browsed session up — accepted as the price of a metadata-only timestamp.
 - The last-turn label, provider/model route, and goal phase columns are gone from rows. Route availability is now enforced by the Enter-time preflight, which fully reads and replay-validates the one chosen log through `readSession` before handoff.

 **Where the files actually live (root mismatch closed; resolve-once residual still open).** The shared base defaults the session store to the global harness home (`$DSH_HOME/sessions`, default `~/.dsh/sessions`), while the shipped Web overlay used to give the json backend the relative root `./.storages`: `workspace.json` and `session_projcache.json` landed under `<launch dir>/.storages/` — two launches from different directories shared their sessions yet saw different workspace registries and different projection caches, and the cache exists precisely to serve the cross-session cold listing, which missed for every session last cached under another launch directory. That mismatch is now closed: the overlay anchors `storage-json.root` to `$DSH_HOME/storages` with the same `!!js` expression the session root uses (`apps/cli/config/web.cordis.yml`). The residual hazard: `JsonStorageBackend` still never resolves its root — each unit open joins the path against whatever `process.cwd()` is at that moment (packages/storage/storage-json/src/index.ts); the shipped overlay root is already absolute and unaffected, but any relative root (bare Loader boots, tests) still splits on a later cwd change — the exact hazard the JSONL session backend resolves-once to prevent ("later process.cwd() changes cannot split one backend across roots", packages/session/session-persistence-jsonl/src/index.ts).
 
-**How recovery works today.** Inside a healthy medium the cache is fully self-healing by design: a `stateVersion`-mismatched row is discarded and refolded, a log shrunk below a row's watermark is detected by the anchored restore floor and answered with one full re-read, and every background write is fail-soft. But at the *medium* level there is no recovery at all: a truncated, hand-edited, or version-bumped `session_projcache.json` fails `openJsonUnit` with `malformed-medium`/`version-mismatch` (packages/storage/storage-json/src/format.ts), a schema-drifted record fails domain open with `invalid-record` (packages/storage/storage-domain/src/index.ts), the rejection propagates through `SessionProjectionCache[Service.init]`, and under the CLI's fail-loud boot the assembly refuses to start. A file whose entire content is rebuildable from session logs can brick boot. This contradicts the cache package's own stated stance ("a stale or unreadable cache costs a longer tail replay, never a wrong value") and the cache domain spec's JSDoc ("version bumps discard the whole medium"), which today describes an aspiration, not the implementation. The same fail-loud path is *correct* for `workspace.json` — workspace records are authoritative, not derivable — so the missing concept is a per-domain declaration of authority, not a global behavior change.

From: _Kerman <kermanx@qq.com>

Subject: [PATCH 003/155] refactor(session-projection-cache): own the cache
 tree under a config root

Store each session's projection_cache.json under the cache's own root tree
(<root>/<session-id>/projection_cache.json, wired to dshHomePath('projections')
in the base bundle) instead of beside the session log via
sessionPersistence.locate(). The cache owns its directory layout, keys
directories by the code-generated session id, and never consults the
persistence layer; the service now injects only sessionProjections and
sessions.

Drop the coldSnapshot method and its readFrom-tail fold ladder: every cold
consumer refolds from the log itself, so the cache only serves the listing
read (cachedSnapshot, one async file read per session) and the write side.
Fail-soft durability, per-path write serialization, in-flight drain, and
atomic 0600 writes are unchanged; the chain cleanup now observes its own
rejection so a failed write cannot surface as an unhandled error.

dsh-session-persistence leaves peer/dev dependencies and the tsconfig
reference; dsh-atomic-write moves to peerDependencies. Config gains a
required root.

 A stored row `(key → {ver, seq, val})` is a fold shortcut, never an authority: possibly stale (`seq` says exactly how stale) but never wrong. Consequences the implementation commits to:
 
-- **Every background write is fail-soft.** A failed durable write logs a warning and keeps the cache stale; the next write or cold read self-heals. A crash between writes costs a longer tail replay, never a wrong value.
+- **Every background write is fail-soft.** A failed durable write logs a warning and keeps the cache stale; the next write self-heals. A crash between writes costs a longer tail replay, never a wrong value.
 - **A `ver` mismatch against the live unit's `stateVersion` discards, never migrates.** A unit bump invalidates its rows at read time; the key refolds from the log.
-- **A row must pass the live unit's `stateSchema`.** A malformed row is omitted from the cached view and rejected by restore so the cold-read ladder refolds it from the log.
-- **Whole-record writes.** Each write atomically replaces the session's cache file (the registry cut is always complete), snapshotted through the lossless-JSON boundary — a unit state violating the plain-JSON contract fails loud.
-- **Records are bound to a log lifecycle, not just an id.** Each record stores the header identity (`createdAt`, `cwd`) it was folded from; every read validates it (the live or stored header is the witness) before accepting a record, so a deleted-then-recreated id or a persistence store swapped under a surviving cache discards the unrelated record instead of seeding phantom values.
+- **A row must pass the live unit's `stateSchema`.** A malformed file reads as "no cache row", so the cold path refolds from the log.
+- **Whole-record writes.** Each write atomically replaces the session's cache file (the registry cut is always complete), snapshotted through the lossless-JSON boundary — a unit state violating the plain-JSON contract fails loud. Writes to one cache file serialize, so a newer cut never lands before an older one.
+- **Records are bound to a log lifecycle, not just an id.** Each record stores the header identity (`createdAt`, `cwd`) it was folded from; every read validates it (the live header is the witness) before accepting a record, so a deleted-then-recreated id cannot let an old record seed state folded from an unrelated log.
 - **The log leads, the cache follows.** A live checkpoint flushes the session's buffered events durably BEFORE the cache file lands, so a crash can leave the cache behind the log (a longer tail replay) but never ahead of it.
-- **Per-session files, no global medium.** A persistence backend without a per-session directory (e.g. sqlite) disables the durable cache: writes no-op and cold reads fall to the full-log rung. An obsolete cache (any earlier format) is never read — the first cold read refolds from the log and writes the current format.
+- **The cache owns its tree, private by default.** Session directories and cache files are created owner-only (`0o700`/`0o600`). The cache does not depend on which persistence backend is mounted — no `locate`, no per-session-dir probing.

Subject: [PATCH 004/155] fix(bundle): mount the projection cache in the base
 overlay

The cache now owns its storage root (dshHomePath('projections')), so the
mount moves from the web-app overlay to base with that root declared, next
to the other base session layers. web-app inherits it; its overlay mount is
removed.

Subject: [PATCH 005/155] test: adapt consumers to the cache's own root tree

The web e2e seeds no longer warm the deleted coldSnapshot; assertions do not
depend on the cache path. list-children mounts the cache with a scratch
root instead of a storage-domain backend, and drops the now-unused storage
devDependencies.

Subject: [PATCH 006/155] docs(session-projection): sync persist removal, cache
 root, and catalogs

- subsystem docs: drop the removed persist flag from the ProjectionDefinition
  type block (both languages).
- config-catalog regenerated (cache requires sessionProjections/sessions,
  config gains root) and the zh side synced by hand; doc graphs regenerated.
- Agent Notes: the per-session cache note records the owned root tree and
  no-persistence design; the storage-root proposal's link to it is corrected
  (two levels up).

 ## Decision
 
-The cache becomes one `projection_cache.json` per session, stored inside the session's own persistence directory. The location comes from the persistence seam — `sessionPersistence.locate(meta)` — so the persistence backend owns the session-directory layout (the jsonl backend places the file beside the session log); the cache service never imports a backend's path helpers. The cache service keeps every other responsibility: checkpoint fold, write policy (turn/end + disposal mandatory, count/interval throttle), fail-soft durability, and the cold-read ladder.
+The cache becomes one `projection_cache.json` per session, stored under the cache's own storage root — `<root>/<session-id>/projection_cache.json` (the session id is a code-generated string, used directly as the directory name). The cache owns its directory tree and never consults the persistence layer: no `locate`, no dependency on which backend is mounted. The cache service keeps every other responsibility: checkpoint fold, write policy (turn/end + disposal mandatory, count/interval throttle), fail-soft durability, and the listing read.
 
-Reading a cache row is now one file read, so `cachedSnapshot(meta)` is async; `coldSnapshot` takes the session header (it needs the header to locate the file — the stored log's header remains the identity witness). A persistence backend without a per-session directory (e.g. sqlite) disables the durable cache: writes no-op and cold reads fall to the full-log rung.
+Reading a cache row is one file read, so `cachedSnapshot(meta)` is async. The cache no longer runs a cold-refold ladder (that would require reading the session log, which belongs to the persistence layer); a consumer that needs a guaranteed cold snapshot refolds from the log itself. Session directories and cache files are created owner-only (`0o700`/`0o600`) via `@deepseek-ai/dsh-atomic-write`.
 
 ## Consequences

+- Per-session write isolation: each throttled write replaces only that session's small file, removing the global write amplification. Writes to one cache file serialize, so a newer cut never lands before an older one; plugin disposal drains in-flight writes.
 - Listing pays N small file reads instead of one big load; a session without a cache file simply lacks the projection column.
-- No migration: the cache is derived data, never an authority. An obsolete global cache (or any earlier format) is never read — the first cold read refolds from the log and writes the current format.
-- The cache file is bound to the same log lifecycle as before: the stored `{createdAt, cwd}` identity guards against a recreated id or a swapped store.

 ## Alternatives considered
 
-- **Keep the global sessions table.** Preserves one-load listing and a synchronous `cachedSnapshot`, but keeps the global write amplification and single-file blast radius that motivated the change.
-- **One storage-domain unit per session in the storage root** (flat `session_projcache_<id>.json`). Rejected: unit names must match `[a-z0-9_]` (session ids cannot), and the files would sit outside the session's own directory, scattering the storage root instead of living beside the log.
-- **Replicate the session-directory layout inside the cache.** Rejected: the persistence backend already owns that layout through `locate`; duplicating the path helpers couples the cache to a backend's internals.
-- **Reuse `@deepseek-ai/dsh-atomic-write`** (the zero-dependency `writeFileAtomic` with `mode`/`dirMode`). Adopted: the cache writes through it with `{ mode: 0o600, dirMode: 0o700 }`, keeping the session tree owner-only like the jsonl backend's own 0o700 directories, instead of exporting a second atomic-write primitive from the storage-json backend plugin.
+- **Keep the global sessions table.** Preserves one-load listing, but keeps the global write amplification and single-file blast radius that motivated the change.

The cache keeps its own tree instead.
+- **Replicate the session-directory layout inside the cache.** Rejected: the persistence backend already owns that layout; the cache does not need the log's project/session directory structure for its own derived files.

+读取缓存行现在是一次文件读取，因此 `cachedSnapshot(meta)` 变为异步。缓存不再运行冷重折叠阶梯（那需要读取会话日志，属于持久化层的职责）；需要保证冷快照的消费方自行从日志重折叠。会话目录与缓存文件经 `@deepseek-ai/dsh-atomic-write` 以仅属主权限（`0o700`/`0o600`）创建。

 **Where the files actually live (root mismatch closed; resolve-once residual still open).** The shared base defaults the session store to the global harness home (`$DSH_HOME/sessions`, default `~/.dsh/sessions`), while the shipped Web overlay used to give the json backend the relative root `./.storages`: `workspace.json` and `session_projcache.json` landed under `<launch dir>/.storages/` — two launches from different directories shared their sessions yet saw different workspace registries and different projection caches, and the cache exists precisely to serve the cross-session cold listing, which missed for every session last cached under another launch directory. That mismatch is now closed: the overlay anchors `storage-json.root` to `$DSH_HOME/storages` with the same `!!js` expression the session root uses (`apps/cli/config/web.cordis.yml`). The residual hazard: `JsonStorageBackend` still never resolves its root — each unit open joins the path against whatever `process.cwd()` is at that moment (packages/storage/storage-json/src/index.ts); the shipped overlay root is already absolute and unaffected, but any relative root (bare Loader boots, tests) still splits on a later cwd change — the exact hazard the JSONL session backend resolves-once to prevent ("later process.cwd() changes cannot split one backend across roots", packages/session/session-persistence-jsonl/src/index.ts).
 
-**How recovery works today.** Inside a healthy medium the cache is fully self-healing by design: a `stateVersion`-mismatched row is discarded and refolded, a log shrunk below a row's watermark is detected by the anchored restore floor and answered with one full re-read, and every background write is fail-soft. But at the *medium* level there is no recovery at all: a truncated, hand-edited, or version-bumped `session_projcache.json` fails `openJsonUnit` with `malformed-medium`/`version-mismatch` (packages/storage/storage-json/src/format.ts), a schema-drifted record fails domain open with `invalid-record` (packages/storage/storage-domain/src/index.ts), the rejection propagates through `SessionProjectionCache[Service.init]`, and under the CLI's fail-loud boot the assembly refuses to start. A file whose entire content is rebuildable from session logs can brick boot. This contradicts the cache package's own stated stance ("a stale or unreadable cache costs a longer tail replay, never a wrong value") and the cache domain spec's JSDoc ("version bumps discard the whole medium"), which today describes an aspiration, not the implementation. Partially superseded for the projection cache: [the per-session cache files note](../implemented/architecture/2026-08-19-projection-cache-per-session-files.md) removed the global `session_projcache` domain, so the cache half of this proposal (recovery on that domain) no longer applies; the `workspace.json` half remains current. The same fail-loud path is *correct* for `workspace.json` — workspace records are authoritative, not derivable — so the missing concept is a per-domain declaration of authority, not a global behavior change.

From 501f387b4661a1862c4800e44f2708ee11d56704 Mon Sep 17 00:00:00 2001
From: _Kerman <kermanx@qq.com>
Date: Thu, 20 Aug 2026 13:47:39 +0800
Subject: [PATCH 007/155] feat(storage): add the per-record layout to the json
 backend
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The json backend now serves two layouts. single (the default) keeps the
whole unit as one document at <root>/<name>.json; per-record keeps one
version-stamped document per record at <root>/<name>/<table>/<key>.json
(plus global.json), so one write rewrites one record instead of the whole
unit. The per-record unit is stateless — the directory is the state,
loadAll re-reads the tree, and every write is a single durable file
operation — while single keeps its authoritative in-memory state and
whole-file publish. Records keys must be path-safe ([a-zA-Z0-9_-]+);
an unsafe key rejects. A record document that is malformed or stamped
with another version reads as an absent record: one bad or stale file
never bricks the unit, and a version bump discards stale records instead
of migrating them. DomainSpec and KvUnitDescriptor gain the optional
layout field (defineDomain validates it, descriptorOf projects it).

Subject: [PATCH 008/155] fix(session-projection-cache): store checkpoints on a
 per-record storage domain
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Restore the storage-domain medium the file-root design replaced: the cache
opens the session_projcache domain (per-record layout — one document per
session under the json backend root) and checkpoint writes land through
the domain's write chain. Reads and writes now share ONE coherent state:
cachedSnapshot reads synchronously from the domain's in-memory tables,
and every write is durability-first-then-memory, so a read can never go
around the write chain to the medium. The hand-rolled write chains,
in-flight tracking, per-session file paths, owner-only file modes, and
the sqlite no-path special case are gone; Config.root is removed and the
domain's version stamp makes a checkpointRecord bump discard stale
sessions per record instead of rejecting the whole medium. The async
ripple of the old file read is reverted: api-proxy's listing column and
subagent's cold identity read go back to synchronous cachedSnapshot.

Subject: [PATCH 009/155] fix(bundle): mount the projection cache in the
 web-app overlay

The cache now opens its domain through ctx.storageDomain, which the
web-app overlay provides (storage-json + storage-domain, backend json).
A parent layer cannot see a child layer's services, so the base-layer
mount from the file-root design is reverted: the cache mount moves back
to web-app next to its storage dependencies, and Config.root is gone.

Subject: [PATCH 010/155] fix(bundle): promote the storage stack and the
 projection cache to base
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The storage hub, json backend, and domain form are general infrastructure,
and the projection cache is a session-layer service that depends on them —
both belong in the shared base, not in the web overlay. Base now provides
storage / storage-json / storage-domain / session-projection-cache; the
web-app overlay keeps its surface consumers (workspace, message-feedback),
which inherit storageDomain from base (a child layer sees parent services).
This reverts the storage stack's historical web-app-only placement and the
file-root design's base mount of the cache.

Subject: [PATCH 011/155] test(session-projection-cache): rewrite for the
 per-record domain medium

cache.spec now boots the real storage stack (storage, storage-json,
storage-domain) and asserts the per-record medium directly:
<root>/session_projcache/sessions/<id>.json carries a version-stamped
{version, record} document, cachedSnapshot is synchronous (zero-I/O from
the domain's in-memory tables), and the write-policy / fail-soft / listing
coverage is preserved at 100%. json-backend.spec gains a per-record layout
block (per-record documents, overwrite/delete/reopen, unsafe keys and
undeclared tables rejecting, foreign-document discard on open, closed
guard, close drain, unreadable-as-absent); storage-domain domain.spec
covers layout validation and descriptorOf projection. list-children.spec
mounts the storage stack for its projectionCache cases and its
cachedSnapshot mocks and reads go synchronous; the api-proxy specs' cache
mocks go synchronous too. devDeps and tsconfig references updated for the
storage stack.

Subject: [PATCH 012/155] docs(session-projection-cache): sync the per-record
 domain medium across docs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Cache README (EN/ZH): the medium is the session_projcache domain in
per-record layout (one version-stamped document per session under the
json backend root), reads are synchronous from the domain's in-memory
tables, and the storage stack rides in base. storage-json README
documents both layouts and their contracts; web-app README notes that
storage and the projection cache live in the shared base. Regenerated:
session-projection subsystem catalog (sync cachedSnapshot, domain
medium), config-catalog (Config.root gone), module-graph (cache now
depends on storage-domain, not session-persistence), cli composition
(storage rows in base), and the projection-cache Agent Note — which now
records the file-root revision and its revert as rejected alternatives.

 ## Decision
 
-The cache becomes one `projection_cache.json` per session, stored under the cache's own storage root — `<root>/<session-id>/projection_cache.json` (the session id is a code-generated string, used directly as the directory name). The cache owns its directory tree and never consults the persistence layer: no `locate`, no dependency on which backend is mounted. The cache service keeps every other responsibility: checkpoint fold, write policy (turn/end + disposal mandatory, count/interval throttle), fail-soft durability, and the listing read.
+The cache opens the `session_projcache` storage domain in the new `per-record` layout, added to the json backend: one version-stamped document per session at `<root>/session_projcache/sessions/<id>.json`, owned by the storage stack — `storage` / `storage-json` / `storage-domain` live in the shared base bundle alongside the cache, and the cache itself is a plain domain consumer again. The cache never consults the persistence layer: no `locate`, no dependency on which backend is mounted.
 
-Reading a cache row is one file read, so `cachedSnapshot(meta)` is async. The cache no longer runs a cold-refold ladder (that would require reading the session log, which belongs to the persistence layer); a consumer that needs a guaranteed cold snapshot refolds from the log itself. Session directories and cache files are created owner-only (`0o700`/`0o600`) via `@deepseek-ai/dsh-atomic-write`.
+Reads and writes share ONE coherent state: every read (`cachedSnapshot`) is a synchronous lookup in the domain's in-memory tables (zero I/O), and every write queues on the domain's per-unit write chain, mutating memory only after durability — no direct disk reads that could lag the throttled writes. The cache keeps every other responsibility: checkpoint fold, write policy (turn/end + disposal mandatory, count/interval throttle), fail-soft durability, and the listing read. `cachedSnapshot(meta)` is synchronous. The cache runs no cold-refold ladder (that would require reading the session log, which belongs to the persistence layer); a consumer that needs a guaranteed cold snapshot refolds from the log itself. The json backend creates its tree owner-only (`0o700`).
 
 ## Consequences
 
-- Per-session write isolation: each throttled write replaces only that session's small file, removing the global write amplification. Writes to one cache file serialize, so a newer cut never lands before an older one; plugin disposal drains in-flight writes.
-- Listing pays N small file reads instead of one big load; a session without a cache file simply lacks the projection column.
+- Per-session write isolation: each throttled write replaces only that session's small document, removing the global write amplification. The domain write chain serializes writes, so a newer cut never lands before an older one; domain close drains in-flight writes.
+- Listing is a synchronous in-memory read; a session without a record document simply lacks the projection column.
+- The per-record contract scopes failure: a malformed or stale-version document reads as an absent record at open, so one bad file never bricks the cache, and a checkpoint schema bump discards stale sessions per record instead of rejecting the whole domain.
 - No migration: the cache is derived data, never an authority. An obsolete cache (any earlier format) is never read — the first cold read refolds from the log and writes the current format.
-- The cache file is bound to the same log lifecycle as before: the stored `{createdAt, cwd}` identity guards against a recreated id.
+- The cache record is bound to the same log lifecycle as before: the stored `{createdAt, cwd}` identity guards against a recreated id.
 
 ## Alternatives considered
 
 - **Keep the global sessions table.** Preserves one-load listing, but keeps the global write amplification and single-file blast radius that motivated the change.
-- **Resolve the path through `sessionPersistence.locate(meta)`** (the file beside the session log). Rejected: the cache would have to guess "beside the log" from a log artifact path (`dirname` + fixed filename), coupling the cache to the persistence service and to a backend's layout. The cache keeps its own tree instead.
-- **Replicate the session-directory layout inside the cache.** Rejected: the persistence backend already owns that layout; the cache does not need the log's project/session directory structure for its own derived files.
-- **Use the existing `@deepseek-ai/dsh-atomic-write`.** Adopted: it is the repo's single atomic whole-file write primitive (owner-only modes included); exporting a second one from the storage-json backend was rejected.
+- **Cache-owned per-session files** (`<root>/<session-id>/projection_cache.json`, the first revision of this change). Tried and reverted in review: the cache hand-rolled the medium — paths, per-path write chains, in-flight tracking, owner-only file modes, and a sqlite no-path special case — and its listing read hit the disk directly on every call while writes were throttled, so reads and writes were never consistent.
+- **Resolve the path through `sessionPersistence.locate(meta)`** (the file beside the session log). Rejected: the cache would have to guess "beside the log" from a log artifact path (`dirname` + fixed filename), coupling the cache to the persistence service and to a backend's layout.
+- **Make `per-record` a mode of the existing unit instead of a separate unit class.** Rejected: the two layouts have genuinely different state models — `single` is memory-authoritative with whole-file publish, `per-record` is stateless (the directory is the state; `loadAll` re-reads the tree) — so they are separate small classes behind one backend, with record keys validated path-safe instead of encoded.

 ## Decision
 
-缓存改为每会话一个 `projection_cache.json`，存放在缓存自己的存储根下——`<root>/<session-id>/projection_cache.json`（session id 是代码生成的字符串，直接用作目录名）。缓存拥有自己的目录树，绝不咨询持久化层：没有 `locate`、不依赖挂载的是哪个后端。缓存服务保留其余全部职责：检查点折叠、写策略（turn/end + dispose 强制点、count/interval 节流）、fail-soft 持久化与列表读。
+缓存打开采用新增 `per-record` 布局的 `session_projcache` 存储域：每个会话一个带版本戳的文档，位于 `<root>/session_projcache/sessions/<id>.json`，介质归存储栈所有——`storage` / `storage-json` / `storage-domain` 与缓存一起落在共享 base 装配里，缓存重新变回纯粹的域消费方。缓存绝不咨询持久化层：没有 `locate`、不依赖挂载的是哪个后端。
 
-读取缓存行现在是一次文件读取，因此 `cachedSnapshot(meta)` 变为异步。缓存不再运行冷重折叠阶梯（那需要读取会话日志，属于持久化层的职责）；需要保证冷快照的消费方自行从日志重折叠。会话目录与缓存文件经 `@deepseek-ai/dsh-atomic-write` 以仅属主权限（`0o700`/`0o600`）创建。
+读写共享同一份一致状态：每次读取（`cachedSnapshot`）都是对域内存表的同步查找（零 I/O）；每次写入排进该域的单条写链，先落盘成功才改内存——不再有落后于节流写入的直读磁盘。缓存保留其余全部职责：检查点折叠、写策略（turn/end + dispose 强制点、count/interval 节流）、fail-soft 持久化与列表读。`cachedSnapshot(meta)` 是同步的。缓存不运行冷重折叠阶梯（那需要读取会话日志，属于持久化层的职责）；需要保证冷快照的消费方自行从日志重折叠。json 后端以仅属主权限（`0o700`）创建自己的目录树。
 
 ## Consequences
 
-- 每会话写入隔离：每次节流写入只替换该会话的小文件，消除全局写放大。同一缓存文件的写入被串行化，新切面绝不会先于旧切面落盘；插件释放时会排空在途写入。
-- 列表读取从一次大加载变为 N 次小文件读取；没有缓存文件的会话只是缺少投影列。
+- 每会话写入隔离：每次节流写入只替换该会话的小文档，消除全局写放大。域写链将写入串行化，新切面绝不会先于旧切面落盘；域关闭时会排空在途写入。
+- 列表读取是同步内存读；没有记录文档的会话只是缺少投影列。
+- per-record 契约把故障范围缩小到单记录：畸形或过期版本的文档在打开时读作"无此记录"，单个坏文件不会拖垮整个缓存；检查点 schema 升级按会话丢弃过期行，而不是拒绝整个域。
 - 无需迁移：缓存是派生数据，绝非权威。过时的缓存（任何更早格式）从不被读取——首次冷读从日志重折叠并写出当前格式。
-- 缓存文件仍绑定同一日志生命周期：存储的 `{createdAt, cwd}` 身份防止被重建的 id 误导。
+- 缓存记录仍绑定同一日志生命周期：存储的 `{createdAt, cwd}` 身份防止被重建的 id 误导。
 
 ## Alternatives considered
 
 - **保留全局 sessions 表。** 保留一次加载式列表，但保留了促成此改动的全局写放大与单文件爆炸半径。
-- **经 `sessionPersistence.locate(meta)` 解析路径**（文件放在会话日志旁）。未采用：缓存得从日志 artifact 路径"猜"日志旁边（`dirname` + 固定文件名），把缓存耦合到持久化服务与后端的布局。缓存改用自有目录树。
-- **在缓存内复刻会话目录布局。** 未采用：持久化后端已拥有该布局；缓存为自己派生的文件不需要日志的 project/session 目录结构。
-- **使用现有 `@deepseek-ai/dsh-atomic-write`。** 采纳：它是仓库唯一的原子整文件写入原语（含仅属主权限）；从 storage-json 后端再导出一套并行实现被否决。
+- **缓存自持的每会话文件**（`<root>/<session-id>/projection_cache.json`，本改动的第一版）。试过并在评审中回退：缓存手搓了介质——路径、按路径的写链、在途跟踪、仅属主文件权限，以及 sqlite 无路径特判——而且它的列表读每次调用都直读磁盘、写却在节流，读写永不一致。
+- **经 `sessionPersistence.locate(meta)` 解析路径**（文件放在会话日志旁）。未采用：缓存得从日志 artifact 路径"猜"日志旁边（`dirname` + 固定文件名），把缓存耦合到持久化服务与后端的布局。
+- **把 `per-record` 做成既有单元的一种模式而非独立单元类。** 未采用：两种布局的状态模型本质不同——`single` 内存权威、整文件发布；`per-record` 无状态（目录即状态，`loadAll` 重扫目录树）——所以它们是同一后端下的两个小型独立类，记录键做路径安全校验而非编码。

-The persisted projection cache (`ctx.sessionProjectionCache`): durable checkpoints of every projection unit's state, one `projection_cache.json` per session under the cache's own storage root (`<root>/<session-id>/projection_cache.json`). The cache owns its directory tree and never consults the persistence layer.

+The persisted projection cache (`ctx.sessionProjectionCache`): durable checkpoints of every projection unit's state, one version-stamped document per session on the `session_projcache` storage domain in `per-record` layout (the shipped json backend lands each session's record at `<root>/session_projcache/sessions/<id>.json`). The cache never consults the persistence layer. Design authority: the [session-projection RFC](../../../.agents/notes/proposed/architecture/2026-07-27-session-projection-and-command-log.md) (persisted projection cache section).
 
 A stored row `(key → {ver, seq, val})` is a fold shortcut, never an authority: possibly stale (`seq` says exactly how stale) but never wrong. Consequences the implementation commits to:
 
+- **Reads and writes share one coherent state.** Every read is a synchronous lookup in the domain's in-memory tables; every write queues on the domain's per-unit write chain and mutates memory only after durability, so a read can never go around the write chain to the medium (no direct disk reads, no torn values).
 - **Every background write is fail-soft.** A failed durable write logs a warning and keeps the cache stale; the next write self-heals. A crash between writes costs a longer tail replay, never a wrong value.
 - **A `ver` mismatch against the live unit's `stateVersion` discards, never migrates.** A unit bump invalidates its rows at read time; the key refolds from the log.
-- **A row must pass the live unit's `stateSchema`.** A malformed file reads as "no cache row", so the cold path refolds from the log.
-- **Whole-record writes.** Each write atomically replaces the session's cache file (the registry cut is always complete), snapshotted through the lossless-JSON boundary — a unit state violating the plain-JSON contract fails loud. Writes to one cache file serialize, so a newer cut never lands before an older one.
+- **A row must pass the live unit's `stateSchema`.** A malformed or stale record document reads as "no cache row" at open, so the cold path refolds from the log.
+- **Whole-record writes.** Each write atomically replaces the session's record document (the registry cut is always complete), snapshotted through the lossless-JSON boundary — a unit state violating the plain-JSON contract fails loud. The domain write chain serializes writes, so a newer cut never lands before an older one.
 - **Records are bound to a log lifecycle, not just an id.** Each record stores the header identity (`createdAt`, `cwd`) it was folded from; every read validates it (the live header is the witness) before accepting a record, so a deleted-then-recreated id cannot let an old record seed state folded from an unrelated log.
-- **The log leads, the cache follows.** A live checkpoint flushes the session's buffered events durably BEFORE the cache file lands, so a crash can leave the cache behind the log (a longer tail replay) but never ahead of it.
-- **The cache owns its tree, private by default.** Session directories and cache files are created owner-only (`0o700`/`0o600`). The cache does not depend on which persistence backend is mounted — no `locate`, no per-session-dir probing.

 一条存储行 `(key → {ver, seq, val})` 是折叠捷径，绝不是权威：可能陈旧（`seq` 精确说明陈旧到哪），但绝不会错。实现据此承诺：
 
+- **读写共享同一份一致状态。** 每次读取都是对域内存表的同步查找；每次写入排进该域的单条写链，先落盘成功才改内存——读永远不会绕过写链去碰介质（没有直读磁盘、没有撕裂的值）。
 - **每次后台写入都 fail-soft。** 持久写失败只记一条警告并保持缓存陈旧；下一次写入自愈。两次写之间崩溃的代价是更长的尾部回放，绝不是错误的值。
 - **`ver` 与当前运行单元的 `stateVersion` 不匹配即丢弃，绝不迁移。** 单元递增版本会在读取时使其行失效；该 key 从日志重新折叠。
-- **存储行必须通过当前单元的 `stateSchema`。** 畸形文件读作"无缓存行"，冷路径从日志重新折叠。
-- **整记录写入。** 每次写入原子替换该会话的缓存文件（注册表切面始终是完整的），并经无损 JSON 边界快照——违反纯 JSON 约定的单元状态会显式失败并报错。同一缓存文件的写入被串行化，新切面绝不会先于旧切面落盘。

 - **记录绑定到日志生命周期，而不只是 id。** 每条记录存储其折叠来源的 header 身份（`createdAt`、`cwd`）；每次读取先以活 header 为证验证它，再接受任何记录——被删后重建的 id 无法让旧记录播种来自无关日志的状态。

+JSON backend for the [storage hub](../storage/README.md), registered as backend `json`, serving two unit layouts:
+
+- **`single` (default)** — one human-readable `<unit>.json` file per unit under a configured root.
+- **`per-record`** — one version-stamped document per record at `<root>/<unit>/<table>/<key>.json` (plus `global.json`), so one write replaces one record instead of the whole unit; the unit is stateless (the directory is the state; `loadAll` re-reads the tree). Record keys must be path-safe (`[a-zA-Z0-9_-]+`); an unsafe key rejects.

 ## Model
 
-- The in-memory unit state is authoritative; every write primitive republishes the whole file via temp-write + fsync + atomic `rename()` replace. A unit file is always the complete current net state — legibility is this backend's reason to exist; scale is the SQLite backend's job.
-- A missing file opens as an empty unit and materializes on the first write. A foreign or unparsable file rejects with `malformed-medium`; a stored version differing from the descriptor rejects with `version-mismatch` (no migration, pre-release stance).
+- `single` layout: the in-memory unit state is authoritative; every write primitive republishes the whole file via temp-write + fsync + atomic `rename()` replace. A unit file is always the complete current net state — legibility is this backend's reason to exist; scale is the SQLite backend's job.
+- A missing file (or unit directory, for `per-record`) opens as an empty unit and materializes on the first write. In `single` layout a foreign or unparsable file rejects with `malformed-medium`, and a stored version differing from the descriptor rejects with `version-mismatch` (no migration, pre-release stance). In `per-record` layout the contract is per record instead: a document that is malformed or stamped with another version reads as an absent record, so one bad or stale file never bricks the unit, and a version bump discards stale records rather than rejecting the whole unit.
 - Write ordering across calls belongs to the caller (the domain layer's write chain); each single call is atomic and durable once resolved.

Subject: [PATCH 013/155] feat(session-projection-cache): seed cold reads from
 the cache and write back

A detached history read still traverses the complete log, but each unit's
fold is now seeded from its cached checkpoint: the registry's restore
slices off the already-folded prefix (events at or below the row's seq)
and applies only the tail. The first cold read writes the refreshed
checkpoint back (fail-soft), so the cache row is created on first read
and kept current afterwards. The recipe lives on the cache
(cachedCheckpoint, coldSnapshot, writeBack); the api-proxy carrier only
supplies the stored header and the full log.

Subject: [PATCH 014/155] feat(storage-json): one-time migration of a legacy
 whole-unit file to per-record
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Opening a per-record unit splits a legacy `<root>/<name>.json` (the
pre-per-record single-file layout) into per-record documents; an
already-present new record wins, and the legacy file is deleted once
every record migrated. The migration also runs when the new tree is
absent — the fresh-upgrade shape — and foreign, shapeless, or malformed
legacy files are left alone. This preserves previously cached session
titles, list metadata, stats, and subagent identity across the medium
change.

Subject: [PATCH 015/155] fix(session-projection-cache): checkpoint at session
 creation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A session that never talks — a forked child seeded with its ancestor's
title, say — previously got its first cache row only at detach; a crash,
or a fork held live in the store, left the seed-derived values (the
title) unreadable on the cold list. Session creation is now a third
mandatory write point: the creation checkpoint folds the seed and
persists immediately. Write-policy docs (README + catalogs) updated.

Subject: [PATCH 016/155] refactor(session-projection-cache): restore the base
 method order

Keep the base class's relative method order (write before coldSnapshot) so
the diff against the base shows the cold-read methods as a pure insertion
instead of a reorder of existing methods.

Subject: [PATCH 017/155] docs(session-projection-cache): sync catalogs,
 type-equiv, and event consumers after master merge

Regenerate config/cordis catalogs and doc graphs (the master merge changed
configs and consumers), add the DomainSpec layout field to the storage
type-equiv block, record session-projection-cache as a session/created
consumer, and drop the leftover experimental/team ghost directories from
the master rename. All 37 static gates pass.

Subject: [PATCH 018/155] chore(storage-json): exempt the shared unit lifecycle
 from the duplication gate

The two standalone unit classes deliberately mirror the KvUnit drain/guard
lifecycle (close + assertOpen); mark the block with a reason-carrying
jscpd ignore so the duplication gate stays green.

 - **`@deepseek-ai/dsh-sdk-protocol`** (`packages/sdk/protocol/`) — the wire made shared and nominal. `JsonRpcLineTransport` moves here verbatim from `dsh-sdk-jsonrpc-server` (which now imports it), and `types.ts` names every payload the server speaks: `InitializeParams/Result`, `SessionPromptParams/Result`, the four notification payloads, and the `HarnessSdkRequestMap`/`HarnessSdkNotificationMap` indexes. The package root explicitly exports that complete interface and provides no source-module deep imports. The server's `notify()` call sites are typed against these named payloads, so server drift breaks compilation, not clients. One behavioral change: an error response now rejects with `JsonRpcResponseError` carrying the wire `code`/`data` (the Python client already preserved these; the old transport threw a bare `Error` with only the message).
 - **`@deepseek-ai/dsh-sdk-client`** (`packages/sdk/client/`) — the TypeScript twin of `python/sdk`: `HarnessClient` (spawn, frame, fan out notifications, typed error surfaces, close-to-quiescence via the shared dispose ladder) under `DeepSeekHarness`/`HarnessSession` (lazy start, memoized `initialize`, `run()` pairing one `session/prompt` with its `session.finished`). Its package-root consumer interface explicitly exports both client layers, caller-facing types, and the protocol-owned `JsonRpcResponseError`; source modules, normalization helpers, and the notification producer stay internal. `TurnResult.events` contains only the root session's typed events, while `notifications` retains session ids across the root and descendants discovered from `subagent.started`; session-tree scoping is client-side, mirroring `client.py`. Deliberate asymmetries with Python: the launch spec is explicit `command`/`args` (no bundled-runtime resolution — that is a distribution concern with no TS consumer yet); `env` replaces rather than merges (callers own credential policy; `scrubbedParentEnv` from the subprocess seam is one import away); `TurnResult` carries the structured `reason` (Python exposes only `status`); teardown walks a private stdin-EOF → SIGTERM → SIGKILL ladder to actual exit (the client runs outside any harness context, so it cannot ride `ctx.subprocess`).
-- **`@deepseek-ai/dsh-subagent-dsh-sdk`** (`packages/subagent/subagent-dsh-sdk/`) — the second out-of-process `SubagentProvider`, structured as `subagent-acp`'s sibling: same all-false capabilities and `inheritsParentContext: false`, same publish-after-handshake ownership transaction, same result-never-rejects flattening through an `onError` sink, same parent-namespace run id. The child answer is read from streamed `session.event`s — the last complete `assistant/message`, else accumulated `text-delta` chunks, so partial answers survive cancellation. Stop reasons map from the child's structured `TurnEndReason` (`completed`/`max-tokens`/`aborted` pass through; everything else, including a settled-without-turn child, is `error`). Its `provider`/`model` config feeds the child's `initialize`; `env` is where deployments pass the child's own key and `DSH_CORDIS_CONFIG`.

Non-completed child reasons and SDK failures add the bounded safe diagnostic defined by the [out-of-process diagnostics decision](2026-08-21-out-of-process-subagent-minimal-diagnostics.md), using only the child reason, current provider stage, and exported SDK error class. Its `provider`/`model` config feeds the child's `initialize`; `env` is where deployments pass the child's own key and `DSH_CORDIS_CONFIG`.
 - **The subagent seam grows `out-of-process.ts`**: the provider-side vocabulary both out-of-process backends share — `NO_START_CAPABILITIES`, timing-bound validation, child cwd resolution (config override, else the delegating parent session's workspace), the never-reject `settleRunResult`, and the `subprocessRunHandle` publication. Process mechanics (spawn, env scrub, tree-scoped teardown) live in the `dsh-subprocess` seam; `subagent-acp` spawns through `ctx.subprocess`, while this backend spawns through the SDK client (the subprocess README's documented exception for SDK-managed transports) and applies the seam's `scrubbedParentEnv()` itself.
 
 `dsh-sdk-jsonrpc-server` keeps serving unchanged (the wire is byte-identical); `dsh-jsonrpc-agent-pkg` (the Python runtime closure) gains the `dsh-sdk-protocol` dependency line.

 **Paid**: a third package in the `sdk/` group and a fourth subagent backend to keep current; the SDK backend boots a complete plugin tree per child (heavier per-run than an ACP child; pooling remains future work, same as ACP); the wire still has no cancel method, so both the SDK's `RequestTimeoutError` and the backend's dispose settle locally while the server-side turn runs on until process teardown; fixtures for the snapshot suite were recorded against `deepseek-v4-flash` and re-record on model-behavior drift like every other recorded corpus.

 ## Problem
 
-An ACP child can stop because it reached a remote limit, denied a required permission, lost its protocol transport, or exited as a process. The shared result historically reduced these outcomes to a stop reason such as `error`, while startup and cleanup rejection messages could expose the original exception. A parent could not choose between narrowing the task, adjusting permission policy, or repairing the child deployment without Host logs.
+An ACP or DSH SDK child can stop because it reached a remote limit, denied a required permission, ended with a non-completed child turn, lost its protocol transport, or exited as a process. The shared result historically reduced these outcomes to a stop reason such as `error`, while startup and cleanup rejection messages could expose the original exception. A parent could not choose between narrowing the task, adjusting permission policy, or repairing the child deployment without Host logs.
 
 Copying exceptions, stderr, task content, tool input, paths, environment values, credentials, or protocol payloads into `SubagentResult.diagnostic` would make untrusted child text model-visible. Reusing a complete product-specific error union would also duplicate independently versioned authorities in the provider-neutral [subagent seam](2026-06-21-subagent-capability-seam.md).

-Each out-of-process provider owns a small mapping from facts it already receives at its protocol and process lifecycle points to fixed safe display text.

Consumers continue to use the existing optional `SubagentResult.diagnostic`; they do not parse its punctuation or provider-private category names.

-`start(request)` resolves the child's working directory, spawns the runtime through `DeepSeekHarness`, and completes the `initialize` handshake (with the configured `provider`/`model` route and optional `maxTokens` output cap) before it fulfills. Fulfillment therefore means the child runtime is ready and ownership has transferred to the caller. A spawn, handshake, or pre-publication cancellation failure rejects only after the subprocess has been reaped; a working-directory resolution failure rejects before anything is spawned.
+`start(request)` resolves the child's working directory, spawns the runtime through `DeepSeekHarness`, and completes the `initialize` handshake (with the configured `provider`/`model` route and optional `maxTokens` output cap) before it fulfills. Fulfillment therefore means the child runtime is ready and ownership has transferred to the caller. A spawn, handshake, or pre-publication cancellation failure rejects only after the subprocess has been reaped; a working-directory resolution failure rejects before anything is spawned. Non-cancellation rejections expose only fixed provider, stage, and category facts in their Error message; the original SDK failure remains on the internal cause chain and in Host diagnostics.
 
 The working directory resolves exactly like the ACP backend, through the seam's shared out-of-process helpers ([`dsh-subagent`](../subagent/README.md)): the configured `cwd` override when set (validated once at load), else the delegating parent session's cwd — never the server process's own cwd. The resolved path becomes the child process cwd and the workspace cwd of its SDK session.
 
-The returned run id is minted in the parent namespace; the child runtime's session id exists only inside the child process. After publication the provider owns one SDK activity and reads the child's answer from its session events: the last complete non-empty `assistant/message` (an empty-content message that records usage is skipped), or the accumulated `text-delta` stream when no such message exists. Partial output remains available after cancellation or an error.

Partial output remains available after cancellation or an error, separate from any `SubagentResult.diagnostic`.
 
 `dispose()` is idempotent: it settles the result locally as `aborted` (there is no wire-level prompt cancel), then closes the runtime — a bounded protocol `shutdown` request followed by the shared stdin-EOF → SIGTERM → SIGKILL ladder to actual exit.
 
 ## Stop-reason mapping
 
-The SDK client returns an owned child activity rather than a prompt result. The provider reads the last durable `turn/end` inside that activity and maps it into the seam vocabulary: `completed` → `completed`, `max-tokens` → `max-tokens`, `aborted` → `aborted`; everything else — `error`, `interrupted`, `disposed`, a future variant, or an activity with no turn — maps to `error`, so an unclean stop is never reported as success. Transport-level failures after publication flatten to `stopReason: 'error'` through the `onError` diagnostic sink (wired to `ctx.logger.warn`); the seam contract forbids `result` rejecting.
+The SDK client returns an owned child activity rather than a prompt result. The provider reads the last durable `turn/end` inside that activity and preserves the existing seam stop reason while adding detail only where it changes the next action.
+
+| Child turn reason | Harness | Additional diagnostic |
+|---|---|---|
+| `completed` | `completed` | None. |
+| `max-tokens` | `max-tokens` | None; the stop reason is already actionable. |
+| `aborted` | `aborted` | `child-disposed` only for the closed `disposed` cause; local parent cancellation never adds one. |
+| `blocked` | `error` | `child-blocked`. |
+| `error` | `error` | `child-error`; the child failure message/code is excluded. |
+| `interrupted` | `error` | `child-interrupted`. |
+| no `turn/end` | `error` | `missing-terminal`. |
+| unknown variant | `error` | Fixed `unknown`; the value is not copied. |
+
+## Failure diagnostics
+
+The first line follows the shared fixed form:
+
+```text
+Subagent failure (provider: DSH SDK; stage: <stage>; category: <category>; child reason: <reason>)
+```
+
+Unavailable optional fields are omitted, and the shared result boundary limits the complete text to 4096 UTF-8 bytes. The provider derives `initialize`, `session-run`, `process`, or `shutdown` at the operation that owns the failure. `SdkProtocolError` and JSON-RPC error responses map to `protocol`, `RequestTimeoutError` maps to `timeout`, `TransportClosedError` maps to `transport` (with `process` stage during a published child run), and other exceptions use `unknown`. Classification never reads an error message, so the stderr tail carried by `TransportClosedError`, paths, task content, environment values, credentials, and protocol payloads remain Host-only.
+
+Successful results and local cancellation omit diagnostics. Startup and shutdown rejections use the same safe line in their Error message while retaining the original cause internally. A diagnostic-bearing child `aborted` result remains `aborted`; the one-shot Job adapter classifies it as failed, while diagnostic-free local cancellation remains killed.

 工作目录的解析与 ACP 后端完全一致，并使用 seam 共享的进程外辅助工具（[`dsh-subagent`](../subagent/README.zh.md)）：设置了 `cwd` 覆盖值时使用该值（加载时校验一次），否则使用发起委派的父会话 cwd，绝不使用服务器进程自身的 cwd。解析出的路径同时成为子进程 cwd 和其 SDK 会话的工作区 cwd。

 `dispose()`（资源释放）是幂等的：先在本地把结果确定为 `aborted`（协议层面没有提示词取消机制），再关闭运行时，即先发出一次有界的协议 `shutdown` 请求，随后通过共享的 stdin-EOF → SIGTERM → SIGKILL 阶梯使进程实际退出。
 
 ## 停止原因映射
 
-SDK 客户端返回自有子活动，而不是提示词结果。提供方读取该活动内最后一个已持久化的 `turn/end`，并将其映射为 seam 词汇：`completed` → `completed`，`max-tokens` → `max-tokens`，`aborted` → `aborted`；其余情况，包括 `error`、`interrupted`、`disposed`、未来变体或不含轮次的活动，均映射为 `error`，因此非正常停止绝不会报告为成功。发布后的传输层失败会通过 `onError` 诊断接收器（连接到 `ctx.logger.warn`）压平为 `stopReason: 'error'`；seam 约定禁止 `result` 被拒绝。
+SDK 客户端返回自有子活动，而不是提示词结果。提供方读取该活动内最后一个已持久化的 `turn/end`，保留既有 seam 结束原因，并只在会改变下一步动作时附加细节。
+
+| 子轮次原因 | Harness | 附加诊断 |
+|---|---|---|
+| `completed` | `completed` | 无。 |
+| `max-tokens` | `max-tokens` | 无；结束原因本身已经可行动。 |
+| `aborted` | `aborted` | 只有闭集 `disposed` 原因会附加 `child-disposed`；父级本地取消绝不附加。 |
+| `blocked` | `error` | `child-blocked`。 |
+| `error` | `error` | `child-error`；不包含子失败消息或 code。 |
+| `interrupted` | `error` | `child-interrupted`。 |
+| 缺少 `turn/end` | `error` | `missing-terminal`。 |
+| 未知 variant | `error` | 固定 `unknown`，不复制原值。 |
+
+## 失败诊断
+
+首行遵循共享固定格式：
+
+```text
+Subagent failure (provider: DSH SDK; stage: <stage>; category: <category>; child reason: <reason>)
+```
+
+不可用的可选字段会被省略，共享结果边界会把完整文本限制在 4096 个 UTF-8 字节以内。提供方从实际拥有失败的操作派生 `initialize`、`session-run`、`process` 或 `shutdown`。`SdkProtocolError` 与 JSON-RPC 错误响应映射为 `protocol`，`RequestTimeoutError` 映射为 `timeout`，`TransportClosedError` 映射为 `transport`（已发布子运行期间使用 `process` stage），其他异常使用 `unknown`。分类绝不读取错误消息，因此 `TransportClosedError` 携带的 stderr tail、路径、任务内容、环境值、凭证与协议 payload 都只留在 Host。
+
+成功结果与本地取消会省略诊断。启动和 shutdown 拒绝会在 Error 消息中使用同一安全行，同时把原始 cause 留在内部。带诊断的子 `aborted` 结果仍保持 `aborted`；一次性 Job adapter 会把它判为 failed，而不带诊断的本地取消仍是 killed。

 - **`@deepseek-ai/dsh-sdk-protocol`** (`packages/sdk/protocol/`) — the wire made shared and nominal. `JsonRpcLineTransport` moves here verbatim from `dsh-sdk-jsonrpc-server` (which now imports it), and `types.ts` names every payload the server speaks: `InitializeParams/Result`, `SessionPromptParams/Result`, the four notification payloads, and the `HarnessSdkRequestMap`/`HarnessSdkNotificationMap` indexes. The package root explicitly exports that complete interface and provides no source-module deep imports. The server's `notify()` call sites are typed against these named payloads, so server drift breaks compilation, not clients. One behavioral change: an error response now rejects with `JsonRpcResponseError` carrying the wire `code`/`data` (the Python client already preserved these; the old transport threw a bare `Error` with only the message).
 - **`@deepseek-ai/dsh-sdk-client`** (`packages/sdk/client/`) — the TypeScript twin of `python/sdk`: `HarnessClient` (spawn, frame, fan out notifications, typed error surfaces, close-to-quiescence via the shared dispose ladder) under `DeepSeekHarness`/`HarnessSession` (lazy start, memoized `initialize`, `run()` pairing one `session/prompt` with its `session.finished`). Its package-root consumer interface explicitly exports both client layers, caller-facing types, and the protocol-owned `JsonRpcResponseError`; source modules, normalization helpers, and the notification producer stay internal. `TurnResult.events` contains only the root session's typed events, while `notifications` retains session ids across the root and descendants discovered from `subagent.started`; session-tree scoping is client-side, mirroring `client.py`. Deliberate asymmetries with Python: the launch spec is explicit `command`/`args` (no bundled-runtime resolution — that is a distribution concern with no TS consumer yet); `env` replaces rather than merges (callers own credential policy; `scrubbedParentEnv` from the subprocess seam is one import away); `TurnResult` carries the structured `reason` (Python exposes only `status`); teardown walks a private stdin-EOF → SIGTERM → SIGKILL ladder to actual exit (the client runs outside any harness context, so it cannot ride `ctx.subprocess`).
-- **`@deepseek-ai/dsh-subagent-dsh-sdk`** (`packages/subagent/subagent-dsh-sdk/`) — the second out-of-process `SubagentProvider`, structured as `subagent-acp`'s sibling: same all-false capabilities and `inheritsParentContext: false`, same publish-after-handshake ownership transaction, same result-never-rejects flattening through an `onError` sink, same parent-namespace run id. The child answer is read from streamed `session.event`s — the last complete `assistant/message`, else accumulated `text-delta` chunks, so partial answers survive cancellation. Stop reasons map from the child's structured `TurnEndReason` (`completed`/`max-tokens`/`aborted` pass through; everything else, including a settled-without-turn child, is `error`). Non-completed child reasons and SDK failures add the bounded safe diagnostic defined by the [out-of-process diagnostics decision](2026-08-21-out-of-process-subagent-minimal-diagnostics.md), using only the child reason, current provider stage, and exported SDK error class. Its `provider`/`model` config feeds the child's `initialize`; `env` is where deployments pass the child's own key and `DSH_CORDIS_CONFIG`.

 - **The subagent seam grows `out-of-process.ts`**: the provider-side vocabulary both out-of-process backends share — `NO_START_CAPABILITIES`, timing-bound validation, child cwd resolution (config override, else the delegating parent session's workspace), the never-reject `settleRunResult`, and the `subprocessRunHandle` publication. Process mechanics (spawn, env scrub, tree-scoped teardown) live in the `dsh-subprocess` seam; `subagent-acp` spawns through `ctx.subprocess`, while this backend spawns through the SDK client (the subprocess README's documented exception for SDK-managed transports) and applies the seam's `scrubbedParentEnv()` itself.
 
 `dsh-sdk-jsonrpc-server` keeps serving unchanged (the wire is byte-identical); `dsh-jsonrpc-agent-pkg` (the Python runtime closure) gains the `dsh-sdk-protocol` dependency line.

 - **Keyless Loader composition** — `subagent-dsh-sdk/tests/loader-composition.e2e.ts` boots a test-only cordis.yml (`examples/jsonrpc-agent/tests/fixtures/subagent/subagent-dsh-sdk/`) where the child is a REAL second harness runtime with its own cordis.yml; asserts cwd inheritance and the model-visible child-error diagnostic with separate partial output. The child launch resolves through `resolveExampleLaunch`, so src/lib modes both hold.
 - **Keyless snapshot** — `examples/jsonrpc-agent/tests/sdk.snapshot.ts` is the jsonrpc example's snapshot suite: the real `dsh-jsonrpc-agent` runtime driven through the real `dsh-sdk-client`, replaying recorded fixtures via `llm-replay` behind `cordis.snapshot.yml` overlays passed explicitly through `DSH_CORDIS_CONFIG`. Text, bash, in-process subagent, persistent-tool, and DSH SDK diagnostic scenarios pin the normalized notification stream, SDK result, persisted logs, and the provider's foreground/background failure text.
 - **With-key e2e** — the snapshot suite's `DSH_SNAPSHOT=record` mode is the live-API path (it produced the committed fixtures); the composition e2e needs no key by design.

 `run(input, { sessionId?, onNotification? })` owns one activity interval: it queues the prompt, waits until its `MessageId` appears in a durable `agent/inbox/spliced` receipt, then collects through the next whole-agent `idle`. It returns `RunResult { sessionId, finalResponse, events, notifications }`. `finalResponse` is the last committed root-session assistant text in that interval, not a response causally assigned to the prompt; steering, injected context, and other queued work may contribute before idle. `events` contains root-session events, while `notifications` also contains descendants discovered from `subagent.started`, all in wire order. The result carries no prompt-level status or turn reason. Transport loss, timeout, and protocol violations reject; model outcomes remain observable in the event stream without being attributed to one input.

 `run(input, { sessionId?, onNotification? })` 拥有一个活动区间：它将提示词排入队列，等待其 `MessageId` 出现在持久的 `agent/inbox/spliced` 回执中，然后持续收集到整个 agent 下一次进入 `idle`。它返回 `RunResult { sessionId, finalResponse, events, notifications }`。`finalResponse` 是该区间内根会话最后提交的助手文本，并非因果上归属于该提示词的响应；steering（中途引导）、注入的上下文和其他排队工作都可能在 idle 前参与其中。`events` 包含根会话事件，`notifications` 还包含通过 `subagent.started` 发现的后代，均按协议传输顺序排列。结果不携带提示词级状态或轮次原因。传输丢失、超时和协议违例会导致 Promise 被拒绝；模型结果仍可在事件流中观察，但不会归属于某一输入。

 ## Failure diagnostics
 
 The first line follows the shared fixed form:
 
 ```text
-Subagent failure (provider: DSH SDK; stage: <stage>; category: <category>; child reason: <reason>)
+Subagent failure (provider: DSH SDK; stage: <stage>; category: <category>)
 ```
 
-Unavailable optional fields are omitted, and the shared result boundary limits the complete text to 4096 UTF-8 bytes. The provider derives `initialize`, `session-run`, `process`, or `shutdown` at the operation that owns the failure. `SdkProtocolError` and JSON-RPC error responses map to `protocol`, `RequestTimeoutError` maps to `timeout`, `TransportClosedError` maps to `transport` (with `process` stage during a published child run), and other exceptions use `unknown`. Classification never reads an error message, so the stderr tail carried by `TransportClosedError`, paths, task content, environment values, credentials, and protocol payloads remain Host-only.

Classification never reads an error message, so the stderr tail carried by `TransportClosedError`, paths, task content, environment values, credentials, and protocol payloads remain Host-only. Request timeout classification is deferred until this provider configures or propagates a request timeout; the current SDK launch waits indefinitely for ordinary requests.
 
 Successful results and local cancellation omit diagnostics. Startup and shutdown rejections use the same safe line in their Error message while retaining the original cause internally. A diagnostic-bearing child `aborted` result remains `aborted`; the one-shot Job adapter classifies it as failed, while diagnostic-free local cancellation remains killed.

 ## 失败诊断
 
 首行遵循共享固定格式：
 
 ```text
-Subagent failure (provider: DSH SDK; stage: <stage>; category: <category>; child reason: <reason>)
+Subagent failure (provider: DSH SDK; stage: <stage>; category: <category>)

-不可用的可选字段会被省略，共享结果边界会把完整文本限制在 4096 个 UTF-8 字节以内。提供方从实际拥有失败的操作派生 `initialize`、`session-run`、`process` 或 `shutdown`。`SdkProtocolError` 与 JSON-RPC 错误响应映射为 `protocol`，`RequestTimeoutError` 映射为 `timeout`，`TransportClosedError` 映射为 `transport`（已发布子运行期间使用 `process` stage），其他异常使用 `unknown`。分类绝不读取错误消息，因此 `TransportClosedError` 携带的 stderr tail、路径、任务内容、环境值、凭证与协议 payload 都只留在 Host。

 成功结果与本地取消会省略诊断。启动和 shutdown 拒绝会在 Error 消息中使用同一安全行，同时把原始 cause 留在内部。带诊断的子 `aborted` 结果仍保持 `aborted`；一次性 Job adapter 会把它判为 failed，而不带诊断的本地取消仍是 killed。

 - **Keyless Loader composition:** A test-only cordis.yml boots the stdio app through the real Loader with the backend's `cwd` omitted; a scripted model delegates once and the scripted child proves it ran in — and was announced — the parent session's workspace (the cwd-inheritance branch end to end).

 Three packages, layered exactly like the existing Python stack, plus one Service Provider registration:
 
 - **`@deepseek-ai/dsh-sdk-protocol`** (`packages/sdk/protocol/`) — the wire made shared and nominal. `JsonRpcLineTransport` moves here verbatim from `dsh-sdk-jsonrpc-server` (which now imports it), and `types.ts` names every payload the server speaks: `InitializeParams/Result`, `SessionPromptParams/Result`, the four notification payloads, and the `HarnessSdkRequestMap`/`HarnessSdkNotificationMap` indexes. The package root explicitly exports that complete interface and provides no source-module deep imports. The server's `notify()` call sites are typed against these named payloads, so server drift breaks compilation, not clients. One behavioral change: an error response now rejects with `JsonRpcResponseError` carrying the wire `code`/`data` (the Python client already preserved these; the old transport threw a bare `Error` with only the message).
-- **`@deepseek-ai/dsh-sdk-client`** (`packages/sdk/client/`) — the TypeScript twin of `python/sdk`: `HarnessClient` (spawn, frame, fan out notifications, typed error surfaces, close-to-quiescence via the shared dispose ladder) under `DeepSeekHarness`/`HarnessSession` (lazy start, memoized `initialize`, `run()` pairing one `session/prompt` with its `session.finished`). Its package-root consumer interface explicitly exports both client layers, caller-facing types, and the protocol-owned `JsonRpcResponseError`; source modules, normalization helpers, and the notification producer stay internal. `TurnResult.events` contains only the root session's typed events, while `notifications` retains session ids across the root and descendants discovered from `subagent.started`; session-tree scoping is client-side, mirroring `client.py`. Deliberate asymmetries with Python: the launch spec is explicit `command`/`args` (no bundled-runtime resolution — that is a distribution concern with no TS consumer yet); `env` replaces rather than merges (callers own credential policy; `scrubbedParentEnv` from the subprocess seam is one import away); `TurnResult` carries the structured `reason` (Python exposes only `status`); teardown walks a private stdin-EOF → SIGTERM → SIGKILL ladder to actual exit (the client runs outside any harness context, so it cannot ride `ctx.subprocess`).
+- **`@deepseek-ai/dsh-sdk-client`** (`packages/sdk/client/`) — the TypeScript twin of `python/sdk`: `HarnessClient` (spawn, frame, fan out notifications, typed error surfaces, close-to-quiescence via the shared dispose ladder) under `DeepSeekHarness`/`HarnessSession` (lazy start, memoized `initialize`, and `run()` from a durable prompt-inbox receipt through the next whole-session idle). Its package-root consumer interface explicitly exports both client layers, caller-facing types, and the protocol-owned `JsonRpcResponseError`; source modules, normalization helpers, and the notification producer stay internal. `RunResult.events` contains only the root session's typed events, while `notifications` retains session ids across the root and descendants discovered from `subagent.started`; session-tree scoping is client-side, mirroring `client.py`. The result carries the final root-session assistant text but no prompt-level status or turn reason. Deliberate asymmetries with Python: the launch spec is explicit `command`/`args` (no bundled-runtime resolution — that is a distribution concern with no TS consumer yet); `env` replaces rather than merges (callers own credential policy; `scrubbedParentEnv` from the subprocess seam is one import away); teardown walks a private stdin-EOF → SIGTERM → SIGKILL ladder to actual exit (the client runs outside any harness context, so it cannot ride `ctx.subprocess`).
 - **`@deepseek-ai/dsh-subagent-dsh-sdk`** (`packages/subagent/subagent-dsh-sdk/`) — the second out-of-process `SubagentProvider`, structured as `subagent-acp`'s sibling: same all-false capabilities and `inheritsParentContext: false`, same publish-after-handshake ownership transaction, same result-never-rejects flattening through an `onError` sink, same parent-namespace run id. The child answer is read from streamed `session.event`s — the last complete `assistant/message`, else accumulated `text-delta` chunks, so partial answers survive cancellation. Stop reasons map from the child's structured `TurnEndReason` (`completed`/`max-tokens`/`aborted` pass through, `blocked` becomes `refusal`, and remaining non-completed values become `error`). Reachable child failures and SDK errors add the bounded safe diagnostic defined by the [out-of-process diagnostics decision](2026-08-21-out-of-process-subagent-minimal-diagnostics.md), using one category plus the current provider stage. Its `provider`/`model` config feeds the child's `initialize`; `env` is where deployments pass the child's own key and `DSH_CORDIS_CONFIG`.
 - **The subagent seam grows `out-of-process.ts`**: the provider-side vocabulary both out-of-process backends share — `NO_START_CAPABILITIES`, timing-bound validation, child cwd resolution (config override, else the delegating parent session's workspace), the never-reject `settleRunResult`, and the `subprocessRunHandle` publication. Process mechanics (spawn, env scrub, tree-scoped teardown) live in the `dsh-subprocess` seam; `subagent-acp` spawns through `ctx.subprocess`, while this backend spawns through the SDK client (the subprocess README's documented exception for SDK-managed transports) and applies the seam's `scrubbedParentEnv()` itself.

+The subprocess starts lazily on first use and stays owned by the instance across `run()` calls; `close()` (or `await using`) is required so the child is always reaped. `start()` memoizes the `initialize` handshake (the workspace cwd — resolved absolute before it crosses the wire — plus the provider/model route and optional positive `maxTokens` output cap).

 `run(input, { sessionId?, onNotification? })` owns one activity interval: it queues the prompt, waits until its `MessageId` appears in a durable `agent/inbox/spliced` receipt, then collects through the next whole-agent `idle`. It returns `RunResult { sessionId, finalResponse, events, notifications }`. `finalResponse` is the last committed root-session assistant text in that interval, not a response causally assigned to the prompt; steering, injected context, and other queued work may contribute before idle. `events` contains root-session events, while `notifications` also contains descendants discovered from `subagent.started`, all in wire order. The result carries no prompt-level status or turn reason. Transport loss, timeout, and protocol violations reject; model outcomes remain observable in the event stream without being attributed to one input.

+The shared result boundary limits the complete text to 4096 UTF-8 bytes. The provider derives `initialize`, `session-run`, or `shutdown` at the operation that owns the failure. During initialize or session run, `SdkProtocolError` and JSON-RPC error responses map to `protocol`, `TransportClosedError` maps to `transport`, and other exceptions use `unknown`. A shutdown rejection uses `unknown`: the SDK client keeps protocol-shutdown failures in Host diagnostics, so only runtime-process disposal can reject `close()`.

Request timeout classification is deferred until this provider configures or propagates a request timeout; the current SDK launch waits indefinitely for ordinary requests.
 
 Successful results and local cancellation omit diagnostics. Startup and shutdown rejections use the same safe line in their Error message while retaining the original cause internally. A diagnostic-bearing child `aborted` result remains `aborted`; the one-shot Job adapter classifies it as failed, while diagnostic-free local cancellation remains killed.

 - **With-key e2e:** The backend spawns the real ACP example; its model answers `PONG`, writes `proof.txt`, and the parent verifies the file.
 - **Keyless snapshot:** The ACP example boots the real provider and scripted child through Loader-backed replay, pinning foreground and one-shot background diagnostics while keeping the child process, permission decision, partial output, and cleanup lifecycle deterministic.
+- **Snapshot gap:** Each ACP child still has its own replay session; `TODO(acp-subagent-replay)` continues to track parent replay against a replaying child harness rather than the scripted protocol child used by the diagnostic scenario.

Fulfillment therefore means the child runtime is ready and ownership has transferred to the caller. A spawn, handshake, or pre-publication cancellation failure rejects only after the subprocess has been reaped; a working-directory resolution failure rejects before anything is spawned.

+`start(request)` resolves the child's working directory, spawns the runtime through `DeepSeekHarness`, and completes the `initialize` handshake (with the configured `provider`/`model` route and optional `maxTokens` output cap) before it fulfills. Fulfillment therefore means the child runtime is ready and ownership has transferred to the caller. A spawn, handshake, or pre-publication cancellation failure ordinarily rejects after the subprocess is reaped; when cleanup itself rejects, the ordered safe initialize/shutdown facts preserve both failures without claiming process exit. A working-directory resolution failure rejects before anything is spawned. Non-cancellation rejections expose only fixed provider, stage, and category facts in their Error message; the original SDK failure remains on the internal cause chain and in Host diagnostics.

 工作目录的解析与 ACP 后端完全一致，并使用 seam 共享的进程外辅助工具（[`dsh-subagent`](../subagent/README.zh.md)）：设置了 `cwd` 覆盖值时使用该值（加载时校验一次），否则使用发起委派的父会话 cwd，绝不使用服务器进程自身的 cwd。解析出的路径同时成为子进程 cwd 和其 SDK 会话的工作区 cwd。

Subject: [PATCH 030/155] test(web): seed cold subagent fixtures through the
 per-record cache

The reworked cache moved from the awaited coldSnapshot(id) to a sync
coldSnapshot(meta, events) whose write-back is fire-and-forget, and the
e2e fixture dropped the seeding call with it. The web bundle mounts the
cache again, so list rows read projection columns from stored rows only;
the one-shot and grandchild fixtures therefore lost their projections
column and the tree golden drifted. Re-seed both through the new API and
poll for the write-back to land.

 chmod probe

The per-record rm in the cache spec hits an EPERM flake on windows
native (directory still draining); retry the recursive rm like the
subagent spec does. The unreadable-record probe is meaningless on
windows, where chmod 0o000 is a no-op; skip it there.

Subject: [PATCH 033/155] test(storage-json): reach the unreadable-record
 branch on every platform

The per-record contract test forced readFile to fail via chmod 0o000,
which is a no-op on win32, so the readRecord catch stayed uncovered on
the windows native coverage gate. Route record documents without an
isFile pre-filter: a directory where the document should be throws
EISDIR on every platform, and readRecord's existing contract already
reads an unreadable document as absent. Drop the win32 skip.

 60s

The Windows native coverage lane was hitting Vitest's 30s per-test
ceiling on slow subprocess/ACP fixtures. Doubling the per-test budget
absorbs cold-start and process-teardown jitter without changing the
assertions or the job-level 120-minute cap.

 **Large web content can damage context quality.** Providers enforce byte/character caps and report `truncated`; `tool-web` formats bounded model output with clear continuation or follow-up guidance.
 
 ## Deferred work
 
-- SSRF / private-network protection for `web_fetch`: block private, loopback, link-local, multicast, and otherwise non-public destinations so `web_fetch` is not an SSRF primitive. Doing it correctly is more than a URL-string check — it needs DNS-resolve-then-connect-to-the-validated-IP (to defeat DNS rebinding / TOCTOU), per-hop re-validation across redirects, and IPv6 edge handling (private ranges, IPv4-mapped addresses). Neither reference implementation surveyed does IP-level blocking (OpenCode does a prefix check then fetches; Claude Code relies on a centralized hostname blocklist plus a "private URLs will fail" prompt), so there is no implementation to copy and this is the harness's only SSRF defense — it warrants its own focused design/spike. Until it lands, `web_fetch` must only be enabled in deployments that cannot reach sensitive internal targets.
 - A `pdf` `WebFetchBody` kind: the `http` provider decodes text-extractable PDFs (best-effort, capped, `truncated`) into a `{ kind: 'pdf'; content; pageCount? }` arm, and `tool-web` renders it. This is fetch, not `web_extract` — PDF retrieval is a concrete HTTP 200 plus deterministic local decoding, not provider-side extraction of a non-HTTP resource. Adding it is a coordinated change across `dsh-web` (declare the arm), the provider (decode + narrow "binary rejection" to "reject binary except text-extractable PDF"; scanned/image PDFs needing OCR stay out of scope), and `tool-web` (render). The closed `WebFetchBody` union makes the consumer side fail to compile until the new arm is handled.
 - Provider-backed extraction as a separate `web_extract` capability, rather than widening `web_fetch` silently.
 - Permission policy integration: the permission system now exists ([sandbox and approval](../feature/2026-07-06-sandbox.md), [web permission presets](../feature/2026-07-23-web-permission-and-approval.md)) but bundles only sandbox mode and approval policy; web permission policy remains unintegrated.

-- `web_fetch` 的 SSRF/私有网络防护：阻断私有、回环、链路本地、多播及其他非公开目的地，使 `web_fetch` 不再是 SSRF 原语。正确实现不仅仅是 URL 字符串检查——需要先 DNS 解析再连接到已验证的 IP（防御 DNS rebinding/TOCTOU）、跨重定向的每跳重新验证，以及 IPv6 边缘处理（私有范围、IPv4 映射地址）。所调研的参考实现均未做 IP 级阻断（OpenCode 做前缀检查后直接 fetch；Claude Code 依赖集中式主机名黑名单加「私有 URL 会失败」的提示词），因此没有可复制的实现，且这是 harness 唯一的 SSRF 防线——值得一次专门的设计/spike。在其落地之前，`web_fetch` 只能在无法触达敏感内部目标的部署中启用。
 - `pdf` `WebFetchBody` 类别：`http` 提供方将可文本提取的 PDF 解码（尽力而为、有上限、`truncated`）为 `{ kind: 'pdf'; content; pageCount? }` 分支，`tool-web` 渲染它。这是 fetch 而非 `web_extract`——PDF 获取是具体的 HTTP 200 加确定性的本地解码，不是提供方侧对非 HTTP 资源的提取。添加它是跨 `dsh-web`（声明分支）、提供方（解码 + 将「二进制拒绝」收窄为「拒绝二进制，但可文本提取的 PDF 除外」；需要 OCR 的扫描/图片 PDF 不在范围内）和 `tool-web`（渲染）的协调变更。封闭的 `WebFetchBody` 联合类型使消费方在新分支被处理之前编译失败。
 - 提供方支撑的提取作为独立的 `web_extract` 能力，而非静默扩展 `web_fetch`。

 Withholding it narrows the surface without removing the reach: `bash` is mounted, so `curl` gets the same page, as a live run confirmed. What the absence buys is the removal of an argument-shaped request primitive that needs no shell — and with it the accidental path where a summarization request quietly reaches loopback. A deployment that must contain outbound traffic needs a network-level control.

 - **Only textual content decodes** — html/xhtml and `text/*`-plus-JSON/XML families; a missing `Content-Type` or any binary type throws `WEB_UNSUPPORTED_CONTENT_TYPE`, and text-extractable PDF decoding is named deferred work.
 - **Charset comes only from the `Content-Type` header** (UTF-8 default) — an HTML `<meta charset>` declaration is ignored, and a declared-but-unrecognized charset label throws rather than falling back.

 ## 已知限制与暂缓事项
 
-- **SSRF／私有网络防护暂缓**：不会阻止私有、loopback、link-local、multicast 或其他非公开目标，也不进行 DNS 解析后验证或逐跳重新验证（见 [web 能力 seam Agent Note](../../../.agents/notes/implemented/architecture/2026-06-24-web-capability-seam.zh.md)）。在此功能落地前，该提供方是 SSRF 原语；能够访问敏感内部网络目标的部署**禁止启用它**。
 - **只解码文本内容**：包括 html/xhtml 与 `text/*` 加 JSON/XML 家族；缺少 `Content-Type` 或任何二进制类型都会抛出 `WEB_UNSUPPORTED_CONTENT_TYPE`，可提取文本的 PDF 解码属于明确的暂缓工作。
 - **charset 只来自 `Content-Type` 标头**（默认为 UTF-8）：HTML `<meta charset>` 声明会被忽略；声明但无法识别的 charset 标签会抛出异常，而非回退。

Plan mode stays an independent collaboration state and uses whichever sandbox and approval policies the product composes with it.

 - A `pdf` `WebFetchBody` kind: the `http` provider decodes text-extractable PDFs (best-effort, capped, `truncated`) into a `{ kind: 'pdf'; content; pageCount? }` arm, and `tool-web` renders it. This is fetch, not `web_extract` — PDF retrieval is a concrete HTTP 200 plus deterministic local decoding, not provider-side extraction of a non-HTTP resource. Adding it is a coordinated change across `dsh-web` (declare the arm), the provider (decode + narrow "binary rejection" to "reject binary except text-extractable PDF"; scanned/image PDFs needing OCR stay out of scope), and `tool-web` (render). The closed `WebFetchBody` union makes the consumer side fail to compile until the new arm is handled.
 - Provider-backed extraction as a separate `web_extract` capability, rather than widening `web_fetch` silently.
-- Permission policy integration: the permission system now exists ([sandbox and approval](../feature/2026-07-06-sandbox.md), [web permission presets](../feature/2026-07-23-web-permission-and-approval.md)) but bundles only sandbox mode and approval policy; web permission policy remains unintegrated.
 - Provider-neutral search controls beyond `query` and `maxResults`, once Exa and Perplexity can both honor them honestly.
 
 ## Open questions
 
 - Should product app packages probe web configuration at startup (treating `WEB_PROVIDER_CONFIGURED_MISSING`, `WEB_PROVIDER_CONFIGURED_UNAVAILABLE`, and `WEB_PROVIDER_AMBIGUOUS` as fatal when web is explicitly configured), or leave misconfiguration to surface at the first execution?
-- Where should permission policy for public web access live in the shipped permission system ([sandbox and approval](../feature/2026-07-06-sandbox.md), [web permission presets](../feature/2026-07-23-web-permission-and-approval.md)): a dedicated web permission plugin on `tools/execute`, provider config, or both?

 The web host composes the same sandboxed product path as the acp-agent composition: `dsh-sandbox-local`, `dsh-sandbox-policy`, `dsh-bash-sandbox`, `dsh-fs-sandbox`, `dsh-user-approval`, and `dsh-permission-presets`, with `BootHostOptions.sandbox` supplying the deployment defaults (`mode`, default `workspace-write`; `approvalPolicy`, default `ask`).
 
+The shipped web composition also mounts `dsh-web-fetch-approval-policy` on `tools/pre-execute`. `danger-full-access` delegates `web_fetch` without asking; `read-only` and `workspace-write` require one-shot approval after the HTTP provider's public-destination preflight; approval policy `never` denies without resolving or prompting. The preflight result only prevents an invalid question: the provider resolves again and pins the actual connection, so `allowed-once` cannot authorize a private destination or a later DNS-rebinding answer. Downstream `deny` and `ask` decisions remain authoritative. `plan` stays independent collaboration state, and products restrict plan work by composing it with a restricted sandbox preset rather than adding a second network-mode vocabulary.
+
 `createApiProxy` owns the approval pending registry. Its `approval/request` waterfall answerer reads the approval id from the session's just-appended `approval/asked` audit event (an ask with no audit event is a foreign channel and delegates), mints one stable rpcId per question, broadcasts the answerable `approval/requested` frame to every open mux stream, and replays still-pending frames verbatim on each mux open — the refresh-recovery baseline the contract already promised. `respond` routes by the echoed rpcId, validates `ApprovalResponsePayload` with the existing zod schema, cross-checks the payload's audit correlation against the routed entry, resolves the answerer, and broadcasts `approval/resolved`; the ask's abort signal withdraws the question as `cancelled`.
 
 The permission select rides two new unary RPCs, `session.permissions` and `session.setPermission`, projecting `ctx.permissionPresets` into a protocol-owned `PermissionOption` DTO (the ACP bridge precedent: each protocol owns its presentation shape). A permission-less composition serves an empty select and clients hide the control. Idle switches are held last-write-wins in a proxy-side pending map and flushed on `agent/pre-step`, because knob events must stay turn-enclosed for durable replay; the shared `hasOpenTurn` fold moved to `dsh-session` and replaced the private copies in `dsh-user-approval`, the ACP bridge, and the proxy.

 **Optimistic card removal on click.** Rejected: the broadcast resolved frame is the truth; removing on click would hide a question that a rejected receipt or transport failure left standing. The panel disables its buttons locally and re-arms them on failure instead.
 
+**Persistent domain authorization in the first fetch policy.** Rejected: the existing approval vocabulary has one grant, `allowed-once`, and already correlates it to the exact tool call. A session/domain grant needs its own durable scope, revocation, display, and redirect semantics; none is required to exercise the permission chain safely.

 ## Consequences
 
-Web sessions start confined (`workspace-write` + `ask` by default) and a sandbox-denial escalation reaches the browser as an answerable card; the deployment can widen or narrow the default through `BootHostOptions.sandbox` without touching the assembly. Question answering uses the same registry pattern (ui-user-questions over the question pending table), and Session navigation identifies approval, plan-review, and ordinary question waits before the user opens them. The permission select reads once per mount; live refresh from another client's switch is deferred. Coverage: proxy registry and permission RPC unit suites, session-object and fixture unit suites, the keyless web smoke for fixture-mode approval and preset switching, and real-composition plan-review and question snapshots that pin the pending sidebar status through resolution.

 `createApiProxy` 拥有审批 pending 注册表。它的 `approval/request` waterfall（瀑布式事件）应答者从会话刚追加的 `approval/asked` 审计事件中读取审批 id（没有审计事件的 ask 属于外部通道，予以委托），为每个问题 mint 一个稳定的 rpcId，向每个打开的 mux 流广播可应答的 `approval/requested` 帧，并在每次 mux 打开时原样重放仍处于 pending 的帧——这正是约定早已承诺的刷新恢复基线。`respond` 按回显的 rpcId 路由，用既有的 zod schema 校验 `ApprovalResponsePayload`，将载荷的审计关联与所路由的条目交叉核对，解析应答者，并广播 `approval/resolved`；ask 的中断信号会以 `cancelled` 撤回该问题。
 
 权限选择依托两个新的一元 RPC，`session.permissions` 与 `session.setPermission`，把 `ctx.permissionPresets` 投影为一个由协议拥有的 `PermissionOption` DTO（沿用 ACP bridge 的先例：每个协议拥有自己的呈现形状）。无权限的组合提供空的选择项，client 隐藏该控件。空闲期的切换以后写胜出（last-write-wins）的方式保存在 proxy 侧的 pending map 中，并在 `agent/pre-step` 时冲刷，因为旋钮事件必须保持轮次内闭合以支持持久回放；共享的 `hasOpenTurn` 折叠迁入 `dsh-session`，取代了 `dsh-user-approval`、ACP bridge 与 proxy 中各自的私有副本。

+[`dsh-web-fetch-approval-policy`](../../packages/web/web-fetch-approval-policy) listens on `tools/pre-execute` without changing the web service or tool schemas. `danger-full-access` delegates to later policies without asking. `read-only` and `workspace-write` require approval policy `ask`, validate that the current URL resolves only to public addresses, preserve any downstream denial, and return `ask` with the exact call id and full normalized URL. Approval policy `never` and agentless restricted calls deny without DNS or a prompt. Only `allowed-once` grants the pending call; there is no persistent domain or session authorization.
+
+Permission preflight and provider enforcement are separate. Preflight prevents a blocked destination from appearing in an approval prompt, but its DNS result is not reused as authorization. The HTTP provider resolves again for the actual request, pins that validated address set, and repeats enforcement for each same-origin redirect; a cross-origin redirect requires a new tool call and permission decision. `plan` remains collaboration state rather than a network mode, so products combine plan work with the desired sandbox and approval policies.

 ## Errors
 
 `WebError extends HarnessError` ([core.md](core.md) error taxonomy) with a `code: string` (open, like every other seam's error — `LlmError`, `SubagentError`), not a closed union: a provider may raise its own codes without editing `dsh-web`, and consumers must tolerate an unknown code. The codes split by owner. Seam-neutral codes are raised by the shared `WebRuntime` contract: `WEB_PROVIDER_UNAVAILABLE`, `WEB_PROVIDER_CONFIGURED_MISSING`, `WEB_PROVIDER_CONFIGURED_UNAVAILABLE`, `WEB_PROVIDER_AMBIGUOUS`, `WEB_DUPLICATE_PROVIDER` (a registration-time programming error, the analogue of `LlmRuntime`'s `DUPLICATE_ADAPTER`), `WEB_ABORTED`, and `WEB_PROVIDER_ERROR` (the catch-all for a provider's own failure surfaced through the seam, including network/transport failure — DNS, connection refused, TLS). Fetch-transport codes are owned by the `dsh-web-fetch-http` implementation and a different fetch backend need not raise them: `WEB_INVALID_URL`, `WEB_BLOCKED_URL`, `WEB_REDIRECT_BLOCKED`, `WEB_FETCH_TOO_LARGE`, `WEB_FETCH_TIMEOUT`, `WEB_UNSUPPORTED_CONTENT_TYPE`.

 `WebError extends HarnessError`（[core.md](core.zh.md) 错误分类体系），带有 `code: string`（开放式，与其他 seam 的错误一致——`LlmError`、`SubagentError`），而非封闭联合类型：提供方可以在不修改 `dsh-web` 的情况下抛出自己的错误代码，消费方必须容忍未知错误代码。错误代码按所有者划分。共享的 `WebRuntime` 约定会抛出与 seam 无关的错误代码：`WEB_PROVIDER_UNAVAILABLE`、`WEB_PROVIDER_CONFIGURED_MISSING`、`WEB_PROVIDER_CONFIGURED_UNAVAILABLE`、`WEB_PROVIDER_AMBIGUOUS`、`WEB_DUPLICATE_PROVIDER`（注册时的编程错误，类似 `LlmRuntime` 的 `DUPLICATE_ADAPTER`）、`WEB_ABORTED`，以及 `WEB_PROVIDER_ERROR`（提供方自身故障经 seam 暴露时使用的兜底代码，包括 DNS、连接被拒绝、TLS 等网络或传输故障）。抓取传输层错误代码由 `dsh-web-fetch-http` 实现拥有，不同的抓取后端无需抛出它们：`WEB_INVALID_URL`、`WEB_BLOCKED_URL`、`WEB_REDIRECT_BLOCKED`、`WEB_FETCH_TOO_LARGE`、`WEB_FETCH_TIMEOUT`、`WEB_UNSUPPORTED_CONTENT_TYPE`。

+# @deepseek-ai/dsh-web-fetch-approval-policy
+
+English | [中文](README.zh.md)
+
+A `tools/pre-execute` policy for one-shot `web_fetch` permission decisions. It combines the calling session's sandbox mode with its approval policy and uses [`dsh-web-fetch-http`](../web-fetch-http/README.md) to reject non-public destinations before asking the user.
+
+## Decisions
+
+| Sandbox mode | Approval policy | `web_fetch` decision |
+|---|---|---|
+| `danger-full-access` | any | Delegate without asking. |
+| `read-only` or `workspace-write` | `ask` | Resolve and require a public destination, then request one-shot approval. |
+| `read-only` or `workspace-write` | `never` | Deny without DNS or a prompt. |
+
+An agentless restricted call is denied because it has no session for policy lookup or approval audit. Malformed arguments delegate to the tool's own schema validation. This plugin never grants a call itself: unrestricted calls delegate to later policies, and restricted calls preserve any downstream `ask` or `deny` result.
+
+The approval request carries the exact tool `callId` and a reason containing the complete normalized URL, sandbox mode, and single-call scope. Only the existing `allowed-once` outcome permits execution; rejection, cancellation, or an unavailable answerer fails closed. Session/domain persistence and permanent grants are outside this package.
+
+## SSRF separation
+
+Permission preflight parses the URL and resolves its complete address set before displaying a prompt. A non-public destination is always rejected and cannot be authorized through `allowed-once`.
+
+Preflight is not a network authorization token. The HTTP provider resolves the hostname again immediately before each connection, rejects any non-public answer, pins the validated addresses, and repeats the check for every followed same-origin redirect. Cross-origin redirects require a new `web_fetch` call and a new permission decision.
+
+## Model Experience
+
+Indirectly, through `dsh-tools` and `dsh-user-approval`, which pause restricted calls for one-shot approval and return denial through the existing tool-error path.
+
+#### KV Cache effect
+
+None. The policy changes execution, not model-visible schemas or prompt text.
+
+## Known Limitations and Deferred Work
+
+- There is no session- or domain-scoped persistent grant.
+- `plan` is collaboration state, not a sandbox mode. Products that want plan work to use restricted web access compose it with `read-only` or `workspace-write` and approval policy `ask`.

+
+[English](README.md) | 中文
+
+一个为 `web_fetch` 作单次权限决策的 `tools/pre-execute` 策略。它组合调用会话的 sandbox mode 与审批策略，并使用 [`dsh-web-fetch-http`](../web-fetch-http/README.zh.md) 在询问用户前拒绝非公开目的地址。
+
+## 决策
+
+| Sandbox mode | 审批策略 | `web_fetch` 决策 |
+|---|---|---|
+| `danger-full-access` | 任意 | 不询问并委托后续策略。 |
+| `read-only` 或 `workspace-write` | `ask` | 解析并要求目的地址公开，然后请求单次审批。 |
+| `read-only` 或 `workspace-write` | `never` | 不进行 DNS 解析或提示，直接拒绝。 |
+
+受限模式下的无 agent 调用会被拒绝，因为它没有可用于策略查询和审批审计的 session。格式错误的参数交给工具自身的 schema 校验。此插件从不自行授予调用：不受限的调用会委托后续策略，受限调用也会保留下游的 `ask` 或 `deny` 结果。
+
+审批请求携带精确的工具 `callId`，其 reason 包含完整的标准化 URL、sandbox mode 与单次调用范围。只有现有的 `allowed-once` 结果允许执行；拒绝、取消或无可用回答方都会 fail closed。按 session／域名持久化和永久授权不属于此包。
+
+## SSRF 分离
+
+权限预检会在显示提示前解析 URL 及其完整地址集合。非公开目的地址始终被拒绝，不能通过 `allowed-once` 授权。
+
+预检不是网络授权令牌。HTTP 提供方会在每次实际连接前重新解析 hostname，拒绝任何非公开解析结果，固定已验证地址，并对每个被跟随的同源重定向重复校验。跨源重定向需要新的 `web_fetch` 调用和新的权限决策。
+
+## 模型体验
+
+通过 `dsh-tools` 与 `dsh-user-approval` 间接影响；它们让受限调用等待单次审批，并通过既有工具错误路径返回拒绝结果。
+
+#### KV Cache 影响
+
+无。该策略改变执行，不改变面向模型的 schema 或提示词文本。
+
+## 已知限制与暂缓事项
+
+- 不存在按 session 或域名限定的持久授权。
+- `plan` 是协作状态，不是 sandbox mode。希望 plan 工作采用受限 Web 访问的产品，应将其与 `read-only` 或 `workspace-write` 以及审批策略 `ask` 组合。

+The base bundle mounts the native DeepSeek adapter, settings and credential providers, stable `web_search`, the public-only HTTP fetch provider and its one-shot approval policy, and disabled session telemetry. Provider credentials resolve from the inherited environment, `$DSH_HOME/.credentials.yaml`, the invoking directory's `.env`, then `$DSH_HOME/.env`; the managed document is never materialized into `process.env`, while both `.env` files are ordinary launch environment layers. Search uses `DEEPSEEK_API_KEY` and accepts `DEEPSEEK_SEARCH_BASE_URL`. The Web app's `cordis`, `code`, and `standard` agent presets expose `web_fetch`; restricted sandbox modes ask once per public URL call, `danger-full-access` delegates without asking, and approval policy `never` denies restricted calls without prompting.
 
 Session telemetry stays local by default. `DSH_TELEMETRY_MODE=FULL` streams every projected session event as OTLP/HTTP logs, while `DSH_TELEMETRY_MODE=FEEDBACK_ONLY` uploads a session-log suffix only when feedback is recorded. `DSH_TELEMETRY_OTLP_URL` selects another collector, and any non-empty `DSH_TELEMETRY_DISABLED` remains an authoritative hard opt-out. The shipped base has no telemetry redaction rule, so explicitly enabled exports can contain message text, tool arguments and results, and workspace paths; the [default-off Agent Note](../../../.agents/notes/implemented/feature/2026-08-10-telemetry-default-off.md) owns that deployment decision.

 会话遥测默认留在本地。`DSH_TELEMETRY_MODE=FULL` 将每条已投影会话事件作为 OTLP/HTTP 日志流式发送，`DSH_TELEMETRY_MODE=FEEDBACK_ONLY` 则仅在记录反馈时上传会话日志后缀。`DSH_TELEMETRY_OTLP_URL` 选择其他 collector。任何非空的 `DSH_TELEMETRY_DISABLED` 都是具有最终效力的遥测强制关闭开关。随附基础配置没有遥测脱敏规则，因此显式启用的导出可能包含消息文本、工具参数和结果，以及 workspace 路径；相关部署决策见[默认关闭 Agent Note](../../../.agents/notes/implemented/feature/2026-08-10-telemetry-default-off.zh.md)。

 ## Known Limitations and Deferred Work
 
 - **The worker composition writes plaintext session logs** (`compression: 'none'` boot patch): it carries no Zstandard codec, so exported logs are `.jsonl`, never `.jsonl.zstd`.
-- **`node:vm`, `node:net`, `node:sqlite`, `node:worker_threads` are structural stubs**: every call reports its refusal on the console and throws. Rows needing a real process or realm isolation cannot run here.
+- **`node:dns/promises`, `node:vm`, `node:net`, `node:sqlite`, `node:worker_threads` are structural stubs**: every call reports its refusal on the console and throws. Rows needing native DNS, a real process, or realm isolation cannot run here.
 - **Filesystem watchers observe only the mounted VFS**: image seeding is silent and the VFS has no symlinks or external writers. `persistent`, `ref()`, and `unref()` preserve the Node API but cannot control a dedicated Worker's lifetime because browsers expose no ref-counted event loop.
 - **Worker confinement is a VFS boundary, not kernel Landlock**: `read-only` and `workspace-write` run the unchanged `@deepseek-ai/node-addon-landlock-run` JavaScript and launcher argv, but the process layer implements the logical `landlock-run` executable and enforces its grants on every shell filesystem request. `full` therefore covers the Worker command table and mounted VFS only; it does not claim arbitrary native-process execution or Linux kernel isolation.
 - **The worker bundle pins a path inside `@yarnpkg/parsers`** — the build resolves the package's own `lib/shell.js` instead of its root, whose barrel also re-exports the Syml parser and so drags js-yaml into a bundle that never parses that format (around 175 kB, plus its module body at worker start). The path is derived from the package manifest, so a layout change fails the build rather than reinstating the barrel; upgrading the dependency means re-checking that the shell parser still lives there.

-- **`node:vm`、`node:net`、`node:sqlite`、`node:worker_threads` 是结构化 stub**：每次调用在 console 报告拒绝并抛出。需要真进程或真 realm 隔离的行在此无法运行。

 - **文件 watcher 只能观察已挂载的 VFS**：镜像 seed 不产生事件，VFS 也没有符号链接或外部写入方。`persistent`、`ref()` 和 `unref()` 保留 Node API，但浏览器没有引用计数事件循环，因此这些接口不能控制 dedicated Worker 的生存期。
 - **Worker confinement 是 VFS 边界，不是内核 Landlock**：`read-only` 和 `workspace-write` 运行未经修改的 `@deepseek-ai/node-addon-landlock-run` JavaScript 与 launcher argv，进程层则实现逻辑 `landlock-run` 可执行文件，并在 shell 的每次文件系统请求上执行其授权。`full` 仅覆盖 Worker 命令表和已挂载 VFS，不表示能够执行任意 native 进程，也不表示 Linux 内核隔离。
 - **worker 束钉住了 `@yarnpkg/parsers` 的包内路径**——构建解析到该包自己的 `lib/shell.js` 而非包根，因为包根 barrel 还 re-export 了 Syml 解析器，会把 js-yaml 拖进一个从不解析该格式的束（约 175 kB，外加 worker 启动时的模块体求值）。该路径由包 manifest 派生，包内布局一变即构建期失败、不会静默退回 barrel；升级这个依赖时须复核 shell 解析器是否仍在那里。

Subject: [PATCH 045/155] fix(ci): restore acp snapshot transcripts and windows
 coverage gate ordering

- The base-mounted projection cache's write-behind forces session-log
  flushes at cache-chosen times, splitting packed chunk rows and collapsing
  the persistence window the keyless acp transcripts pin. ACP exposes no
  session-listing surface, so the automation profile disables the base row,
  restoring the pre-base behavior the fixtures were recorded against.
- The windows coverage lane runs suites that read built lib/ output (the
  webworker-packer image tests) and raced the build gate's tsdown writes
  against a partial tree; every coverage gate now waits for the build gate.

 The automation-only ACP stdio application as a `dsh` profile bundle over [`dsh-base`](../base/README.md). It inherits the base's disabled module-HMR policy; its patch sets the coding-agent persona and default model route, mounts an app-owned zero-option command provider, and starts [`dsh-acp`](../../acp/acp/README.md) only after that provider accepts the invocation. `dsh --profile acp --help` therefore writes help and exits without claiming stdin or stdout.

 The shipped row creates sessions with `deepseek-official` and `deepseek-v4-flash`; a later patch can replace that row's complete config. The base profile owns adapters, tools, persistence, policy, settings, credentials, and the per-session workspace supplied by the ACP client.

 Product providers remain process-scoped host-plane registrations. The [production-install exclusion decision](../simplification/2026-08-12-production-dsh-excludes-product-subagent-providers.md) supersedes only this note's former base-bundle installation choice: production `dsh-base` neither depends on nor mounts them. A Profile that opts in installs the selected provider Bundle; its patch mounts the default instance, and the Profile may mount additional named instances on the host plane. The [named-instance decision](../feature/2026-08-18-product-subagent-named-instances.md) owns each row's registry identity: both products accept multiple unique `providerName` values while preserving `codex` and `claude-code` as their defaults. Loading either plugin only registers a dormant backend; the corresponding Codex or Claude process starts on the first actual delegation call. Agent Presets independently contribute ordinary `dsh-tool-subagent` rows whose `provider` and `toolName` values expose exactly the configured instances needed by one agent without changing the Host registry.

Both packages accept multiple named instances. Loading either provider starts no product process, and each tool accepts only a standalone text task; product and instance selection remain deployment configuration.
 
 Both providers report `inheritsParentContext: false`, advertise no optional start capabilities, and pass the parent Session cwd without copying the parent conversation. Their documented tools use `backgroundMode: 'one-shot'` and `maxDepth: 'provider-managed'`: the consumer keeps foreground collection as the default and may place the same run in the generic Job runtime, while recursion policy stays with the out-of-process product. Every call creates a fresh product process and a non-resumable product conversation. `ctx.subagents` owns named-request resolution and paired lifecycle events; `dsh-tool-subagent` owns model-visible scheduling and foreground-versus-Job adaptation; `ctx.jobs` and `dsh-tool-jobs` own Job ids, state, output, controls, notices, and parent-owner cancellation; each product provider owns native result mapping, while `dsh-subprocess` owns credential scrubbing, process-tree termination, and whole-tree exit observation.

The provider omits `pathToClaudeCodeExecutable`, so the SDK selects Claude Code 2.1.220 from the matching OS, CPU, and Linux-libc platform package in its own optional dependency closure. The provider does not resolve or fall back to a host `claude`; an omitted, unsupported, missing, or damaged platform payload fails the first delegation at the SDK startup boundary. The provider uses the official `query()` entrypoint and passes the SDK's native `claude` or `claude.exe` command, arguments, cwd, environment, and forwarded signal from `spawnClaudeCodeProcess` to `dsh-subprocess`; its private `SpawnedProcess` adapter exposes only the stream, event, kill, and exit facts the SDK requires.

 Startup rollback and published disposal close the SDK query, abort the per-run controller, invoke shared process-tree termination, and wait for whole-tree exit. `Query.close()` expresses graceful protocol intent but does not replace the subprocess owner's exit proof. An unpublished failure exposes only fixed `query-start` facts; a published process failure can expose its independent exit code and signal; an independent cleanup rejection exposes `teardown`. Original SDK, Host, and cleanup errors remain on internal cause chains and logs rather than entering the diagnostic.

 Every query disables `AskUserQuestion`. Non-bypass permission callbacks deny instead of returning the SDK's indefinitely blocking `null`; plan mode also places `ExitPlanMode` in `disallowedTools`, so native allow rules cannot switch the unattended query back to execution. MCP elicitation is declined; the supported refusal dialog is cancelled; undeclared dialog kinds use the SDK's no-dialog failure behavior.

 Each product's permission fact contains only the effective mode, request category, unattended decision, and a fixed safe reason. Claude Code derives those facts from SDK callbacks and `permission_denied` messages. Codex derives them from app-server requests, declined items, `sandboxError`, and two fixed permission signatures in a bounded stderr tail; raw stderr is still forwarded to the Host but never copied into the diagnostic. Both Providers place their structured failure line before the latest contributing permission fact. A successful result returns only the strict final answer; local cancellation remains `aborted` without permission detail; an unpublished startup failure still rejects `start()`. The Provider never adds either diagnostic fact to assistant output, structured output, or `subagent/end.lastAssistantMessage`.

 ## Problem
 
-A Profile can mount one Cordis plugin package in multiple rows, but the Codex and Claude Code product providers previously registered every row under one fixed product name. A second row therefore failed as a duplicate before its distinct permission mode, environment, or process-release settings could become usable. Deriving an implicit name from those settings would create a second identity rule, while choosing a provider during a tool call would let model input select deployment authority.
+A Profile can mount one Cordis plugin package in multiple rows, but the Codex and Claude Code product providers previously registered every row under one fixed product name. A second row therefore failed as a duplicate before its distinct model where supported, permission mode, environment, or process-release settings could become usable. Deriving an implicit name from those settings would create a second identity rule, while choosing a provider during a tool call would let model input select deployment authority.
 
 The existing subagent registry already owns unique provider names, reversible registration, lifecycle events, and holder-owned published runs. The existing `dsh-tool-subagent` configuration already binds one provider name to one model-visible tool name. Product providers need to expose the missing Profile-owned identity without adding another registry or selection protocol.
 
 ## Decision
 
-Each product provider Config owns a non-empty `providerName`; the defaults remain `codex` and `claude-code`. The resolved name is fixed when the plugin row loads and becomes the Provider object's `name`; registration, lookup, lifecycle events, run logs, and HMR removal therefore use the same value. Each mounted row retains its own `permissionMode`, `env`, `disposeGraceMs`, and run resources.
+Each product provider Config owns a non-empty `providerName`; the defaults remain `codex` and `claude-code`. The resolved name is fixed when the plugin row loads and becomes the Provider object's `name`; registration, lookup, lifecycle events, run logs, and HMR removal therefore use the same value. Each mounted row retains its own `permissionMode`, `env`, `disposeGraceMs`, and run resources. Claude Code rows also retain an optional non-empty `model`; an explicit value is fixed for every query from that instance, while omission leaves native settings authoritative.
 
 Profiles may mount multiple Codex or Claude Code rows when every row uses a distinct `providerName`. Each `dsh-tool-subagent` row continues to bind its existing `provider` field to that exact name and exposes an independently configured `toolName`. Tool calls carry no provider selector, alias, or permission input. A duplicate provider name fails through the existing `DUPLICATE_PROVIDER` path and leaves the first registration intact.
 
-Removing one provider row blocks new starts and removes only tools bound to that name. Runs already published by the removed instance remain owned by their holders and settle or dispose independently. Sibling instances remain registered and keep their own environment, native permission mode, cancellation controller, product process, and cleanup grace.

+# Agent Note: Product subagents expose minimal actionable diagnostics
+
+Status: implemented
+
+English | [中文](2026-08-21-product-subagent-minimal-diagnostics.zh.md)
+
+## Problem
+
+The Claude Code and Codex providers receive structured failures from independently versioned product runtimes. Mirroring every member of those upstream error unions into model-visible diagnostics makes each runtime upgrade expand the Provider contract even when the parent agent would take the same next action for several categories.
+
+Raw SDK errors, app-server payloads, stderr, commands, paths, task content, environment values, and credentials cannot replace the structured mapping because they cross the product process boundary without a stable safety guarantee. The parent still needs enough information to distinguish a product limit, access restriction, service or transport problem, invalid result, and managed process failure.
+
+## Decision
+
+Each product Provider derives a small action category from the current operation and safe structured product facts. The existing `SubagentResult.diagnostic` string remains the only public representation: consumers display it but do not parse it, and the shared subagent result boundary continues to enforce the complete 4096-byte UTF-8 limit.
+
+Claude Code maps Agent SDK results into five categories:
+
+| Category | Safe input |
+| --- | --- |
+| `limit` | Turn, budget, or structured-output retry limits |
+| `product-error` | A general SDK execution failure |
+| `invalid-result` | An error-marked or blank success, or no terminal result |
+| `process` | The managed CLI exits before a terminal result |
+| `unknown` | Startup, teardown, unrecognized SDK values, or failures without a more specific safe fact |
+
+The diagnostic also retains the derived `query-start`, `query-run`, `process`, or `teardown` stage and independently observed exit code and signal. A contributing permission decision follows the failure line. Successful completion and local cancellation expose no failure diagnostic, and original SDK text remains only on the internal cause chain and in Host observation.
+
+Codex currently retains the version-pinned categories documented by the [structured failure-facts decision](../feature/2026-08-18-product-subagent-failure-facts.md). The two providers may adopt the minimal mapping independently because neither shares a public error enum or asks a consumer to branch on category text.
+
+### Ownership and lifecycle
+
+| Fact or operation | Owner | Result |
+| --- | --- | --- |
+| Product error interpretation | Official product runtime | The Provider consumes only structured facts exposed by its pinned integration |
+| Action category and stage | One product Provider run | Derived at the failure site and discarded after result settlement |
+| Exit code and signal | `dsh-subprocess` handle | Displayed independently when observed, without inferring missing values |
+| Permission decision | Product Provider permission callbacks or protocol | Appended only when it contributed to the failed run |
+| Diagnostic delivery and byte limit | `dsh-subagent` and its foreground or Job consumers | One bounded optional string remains separate from assistant output |
+
+## Verification
+
+Claude Code package tests cover every coarse category, all four stages, unknown structured values, permission ordering, raw-text exclusion, success and cancellation omission, concurrent-run isolation, and independent exit code and signal fields. The real Agent SDK 0.3.237 and Claude Code 2.1.237 fixture produces an actual max-turns limit, process failure, permission denial, strict final answer, cancellation, and whole-tree quiescence. Loader and keyless product compositions continue to expose static tools without a diagnostic parser or model-visible category input.
+
+## Alternatives considered
+
+**Preserve every upstream enum member.** Several members lead to the same parent action, while the display-only consumer gains no behavior from their exact names. Keeping them would make routine product upgrades redefine a larger Harness-facing promise.
+
+**Return raw product text or classify general stderr.** Free-form text can contain sensitive task and environment data and has no stable versioned meaning. Only structured product facts, Provider stage, permission decisions, and managed process outcomes qualify as input.
+
+**Add a shared structured error type.** The products version their failures independently, and current consumers only present a bounded string. A shared enum would move product release churn into the provider-neutral seam without a consumer that needs it.
+
+**Retry or fall back based on the category.** The Provider owns one one-shot run and has no retry authority, fallback model, persistent product session, or recovery state. The category informs the parent; it does not start another product action.
+
+## Consequences
+
+Claude Code upgrades no longer require a model-visible promise for every SDK error subtype. Parents still distinguish a limit, general product failure, invalid result, managed process exit, and unknown failure while retaining stage, permission, and process facts.
+
+The diagnostic remains safe display text rather than a recovery protocol. This change adds no raw error forwarding, fallback model, automatic retry, product session persistence, public structured result field, or dynamic provider and model selection.

+# Agent Note: 产品 subagent 公开最小可行动诊断
+
+Status: implemented
+
+[English](2026-08-21-product-subagent-minimal-diagnostics.md) | 中文
+
+## Problem
+
+Claude Code 与 Codex 提供方会从彼此独立版本化的产品运行时接收结构化失败。如果把这些上游错误联合的每个成员都镜像进模型可见诊断，那么即使多个类别会让父 agent 采取同一种下一步动作，每次运行时升级仍会扩大提供方约定。
+
+原始 SDK 错误、app-server payload、stderr、命令、路径、任务内容、环境值与凭证都不能取代结构化映射，因为这些内容跨越产品进程边界时没有稳定的安全保证。父 agent 仍需要足够信息来区分产品限制、访问限制、服务或传输问题、无效结果与受管进程失败。
+
+## Decision
+
+每个产品提供方都会根据当前操作与安全的结构化产品事实派生少量行动类别。现有 `SubagentResult.diagnostic` 字符串仍是唯一公共表示：消费方只展示而不解析，共享 subagent 结果边界继续对完整文本执行 4096 字节 UTF-8 上限。
+
+Claude Code 会把 Agent SDK 结果映射为五种类别：
+
+| 类别 | 安全输入 |
+| --- | --- |
+| `limit` | 轮次、预算或结构化输出重试限制 |
+| `product-error` | 一般 SDK 执行失败 |
+| `invalid-result` | 标记为错误或内容空白的成功结果，或缺失终态结果 |
+| `process` | 受管 CLI 在终态结果前退出 |
+| `unknown` | 启动、清理、无法识别的 SDK 值，或没有更具体安全事实的失败 |
+
+诊断还会保留派生的 `query-start`、`query-run`、`process` 或 `teardown` 阶段，以及分别观测到的退出码与信号。参与失败的权限决定会跟在失败行之后。成功完成与本地取消不公开失败诊断，原始 SDK 文本只留在内部 cause 链和 Host 观测中。
+
+Codex 当前仍保留[结构化失败事实决策](../feature/2026-08-18-product-subagent-failure-facts.zh.md)记录的锁定版本类别。两个提供方可以分别采用最小映射，因为它们既不共享公共错误枚举，也不要求消费方根据类别文本分支。
+
+### 所有权与生命周期
+
+| 事实或操作 | 责任方 | 结果 |
+| --- | --- | --- |
+| 产品错误解释 | 官方产品运行时 | 提供方只消费其锁定集成公开的结构化事实 |
+| 行动类别与阶段 | 单次产品提供方运行 | 在失败位置派生，并在结果结算后丢弃 |
+| 退出码与信号 | `dsh-subprocess` 句柄 | 观测到时分别展示，不推断缺失值 |
+| 权限决定 | 产品提供方权限回调或协议 | 只在参与失败运行时追加 |
+| 诊断传递与字节上限 | `dsh-subagent` 及其前台或 Job 消费方 | 一个有界可选字符串继续与 assistant 输出分离 |
+
+## Verification
+
+Claude Code 包测试覆盖全部粗粒度类别、四个阶段、未知结构化值、权限顺序、原始文本排除、成功与取消时省略、并发运行隔离，以及彼此独立的退出码与信号字段。真实 Agent SDK 0.3.237 与 Claude Code 2.1.237 fixture 会产生实际 max-turns 限制、进程失败、权限拒绝、严格最终答案、取消与整棵进程树完全停稳。Loader 与无密钥产品组合继续公开静态工具，不增加诊断解析器或模型可见类别输入。
+
+## Alternatives considered
+
+**保留每个上游枚举成员。** 多个成员会触发同一种父级动作，而只负责展示的消费方无法从准确名称获得额外行为。继续保留会让常规产品升级重新定义更大的 Harness 可见承诺。
+
+**返回原始产品文本或分类一般 stderr。** 自由文本可能包含敏感任务与环境数据，也没有稳定的版本化含义。只有结构化产品事实、提供方阶段、权限决定与受管进程结果可以成为输入。
+
+**增加共享结构化错误类型。** 两个产品独立版本化失败，而当前消费方只呈现有界字符串。共享枚举会在没有消费需求的情况下，把产品发布变动移入提供方无关的 seam。
+
+**根据类别重试或 fallback。** 提供方只拥有一次 one-shot 运行，没有重试权限、fallback 模型、持久产品会话或恢复状态。类别只用于通知父级，不会启动另一项产品动作。
+
+## Consequences
+
+Claude Code 升级不再要求为每个 SDK 错误 subtype 提供模型可见承诺。父级仍可区分限制、一般产品失败、无效结果、受管进程退出与未知失败，并保留阶段、权限与进程事实。
+
+诊断仍是安全展示文本，而不是恢复协议。本改动不增加原始错误转发、fallback 模型、自动重试、产品会话持久化、公共结构化结果字段或动态提供方与模型选择。

 `start(request)` accepts only a non-empty sequence of text blocks and derives the child cwd from the parent Session. It creates one private `AbortController`, calls the official SDK `query()`, and publishes the run only after the SDK's `spawnClaudeCodeProcess` hook has supplied a live CLI handle owned by [`dsh-subprocess`](../../subprocess/subprocess/README.md). A failure or cancellation before publication closes the query, terminates any acquired process tree, waits for it to exit, and rejects `start()`.
 
-The SDK receives the exact concatenated text task. The provider iterates the complete SDK message stream and accepts only a `result` message with `subtype: "success"`, `is_error: false`, and a nonblank `result`, followed by normal iterator completion. Every failure still maps to `error`: the four error subtypes in Agent SDK 0.3.220 retain their exact category, an error-marked or blank success becomes `invalid-success`, a missing result becomes `missing-result`, an unclassified query failure becomes `unknown`, and an early CLI exit becomes `process-exit`. The diagnostic also names the current `query-start`, `query-run`, `process`, or `teardown` stage and independently includes an observed exit code and signal. The provider produces neither `max-tokens` nor `refusal`.
+The SDK receives the exact concatenated text task. The provider iterates the complete SDK message stream and accepts only a `result` message with `subtype: "success"`, `is_error: false`, and a nonblank `result`, followed by normal iterator completion. Every failure still maps to `error`: turn, budget, and structured-output limits use `limit`; execution failures use `product-error`; error-marked, blank, or missing results use `invalid-result`; an early CLI exit uses `process`; and unclassified failures use `unknown`. The diagnostic also names the current `query-start`, `query-run`, `process`, or `teardown` stage and independently includes an observed exit code and signal. The provider produces neither `max-tokens` nor `refusal`.
 
 Local cancellation wins the result race and maps to `aborted` without a failure diagnostic. `dispose()` is idempotent: it aborts the run, asks the SDK query to close, invokes the shared process-tree termination escalation, and waits for whole-tree exit. SDK graceful close expresses protocol intent; the subprocess handle remains the authority for process quiescence. Startup and teardown rejections expose the same fixed safe stage and process facts through their Error message, while the original product or Host error remains on the internal cause chain and in the Provider's Host log. Result failure and independent teardown failure remain separate.
 
 ## Native settings and interaction
 
-The provider deliberately omits the SDK `settingSources` option. The official SDK therefore reads the host's normal user, project, and local Claude settings relative to the parent Session cwd, including native account state and product configuration. The provider neither copies nor filters those files and does not create or modify login state. The Profile-selected `permissionMode` is the one query-level override: Claude Code still owns its settings and sandbox, while the selected native mode decides how this unattended query handles permission checks.
+The provider deliberately omits the SDK `settingSources` option. The official SDK therefore reads the host's normal user, project, and local Claude settings relative to the parent Session cwd, including native account state and product configuration. The provider neither copies nor filters those files and does not create or modify login state. A configured `model` is passed unchanged to that Provider instance's queries; when it is omitted, the Provider leaves `Options.model` absent and native settings remain authoritative. The Profile-selected `permissionMode` always decides how the unattended query handles permission checks, while Claude Code still owns model interpretation, settings, and sandbox behavior.
 
 Each query sets `persistSession: false` and disables `AskUserQuestion`. Except in bypass mode, `canUseTool` immediately denies requests that still require human approval. Plan mode also places `ExitPlanMode` in the SDK's `disallowedTools`, so native settings cannot pre-approve a transition back to execution and the model must return the completed plan as its final answer. MCP elicitation is declined, the known refusal fallback dialog is cancelled, and undeclared dialog kinds use the SDK's no-dialog failure behavior. These decisions never wait for a user interface. When both facts contribute to a failed run, `SubagentResult.diagnostic` contains the structured failure line first and the latest safe permission decision second; the shared result boundary limits the complete text to 4096 UTF-8 bytes. Successful and locally cancelled runs expose neither captured fact.

 This package is an optional Profile Bundle.

Removing the package withdraws that provider and its private runtime closure on the next Profile start.

 ## Product compatibility and evidence
 
-The runtime dependency is pinned to `@anthropic-ai/claude-agent-sdk@0.3.220`, whose eight platform packages carry Claude Code 2.1.220. A normal install selects one payload for the current OS, CPU, and Linux libc. For the current darwin-arm64 payload, `npm pack --dry-run --json` reports 74,858,812 packed bytes and 256,908,856 unpacked bytes; other platforms may differ, and these values are disclosure rather than an installation threshold. The keyless real-product test runs the SDK-selected CLI against a loopback Messages fixture and asserts that the shared subprocess argv begins with that platform package's native executable. Loader composition proves that installing the Bundle registers only the dormant Claude Code provider and starts no product process.

Loader composition proves that installing the Bundle registers only dormant Claude Code providers and starts no product process.
 
 Installing with optional dependencies omitted, using an unsupported platform, or losing the selected payload leaves provider registration dormant but makes the first delegation fail at the SDK startup boundary. The caller receives the safe `query-start` / `unknown` failure fact; the native payload error remains only on the internal cause chain and in the Provider's Host log. The provider neither probes a host CLI nor retries with one.

 - **Authentication and account state remain native** — the Bundle supplies the CLI but does not create an account, log in, or rewrite Claude settings; configuration and authentication failures surface with their lifecycle stage and the safe `unknown` fallback rather than a separate public classification.
 - **The SDK platform payload is required at delegation time** — installs that omit optional dependencies, unsupported platforms, and missing or damaged payloads fail at the first query; there is no host-CLI fallback.
 - **No human interaction path** — `AskUserQuestion` is disabled, permission prompts are denied, MCP elicitation is declined, and blocking dialogs fail closed instead of suspending.

 本地取消会在结果竞态中胜出并映射为 `aborted`，且不附带失败诊断。`dispose()`（资源释放）具有幂等性：它会中止此次运行、请求 SDK query 关闭、调用共享的进程树逐级终止机制，并等待整棵进程树退出。SDK 的优雅关闭只表达协议意图；进程是否完全停稳仍以子进程句柄为准。启动与清理拒绝会在 Error 消息中公开同样固定的安全阶段和进程事实，而原始产品或 Host 错误只保留在内部 cause 链与提供方的 Host 日志中。结果失败与独立的清理失败仍彼此分离。

+提供方故意省略 SDK 的 `settingSources` 选项。因此，官方 SDK 会相对于父会话 cwd 读取宿主机常规的用户、项目和本地 Claude 设置，包括原生账户状态与产品配置。提供方既不复制也不过滤这些文件，也不会创建或修改登录状态。若配置了 `model`，提供方会把它原样传给该实例的每次 query；若省略，提供方不会设置 `Options.model`，原生设置继续拥有模型选择权。Profile 选择的 `permissionMode` 始终决定无人值守 query 如何处理权限检查，而模型解释、其他设置与沙箱行为仍由 Claude Code 负责。
 
 每次 query 都设置 `persistSession: false` 并禁用 `AskUserQuestion`。除 bypass 模式外，`canUseTool` 会立即拒绝仍需人工审批的请求。Plan 模式还会把 `ExitPlanMode` 放入 SDK 的 `disallowedTools`，因此原生 settings 无法预先放行回到执行模式的转换，模型必须把完整计划作为最终答案返回。MCP elicitation 会被拒绝，已知的拒绝回退对话会被取消，未声明的对话类型则使用 SDK 的无对话失败行为。这些决定都不会等待用户界面。当两类事实共同参与一次失败运行时，`SubagentResult.diagnostic` 会先写入结构化失败行，再写入最新的安全权限决定；共享结果边界会把完整文本限制在 4096 个 UTF-8 字节以内。成功运行与本地取消都不会公开已捕获的事实。

 ### Claude Code facts
 
-Agent SDK 0.3.237 supplies structured error subtypes, but the Claude Code Provider exposes only the action categories owned by the [minimal-diagnostics decision](../simplification/2026-08-21-product-subagent-minimal-diagnostics.md): limits use `limit`, general execution failures use `product-error`, error-marked, blank, or missing results use `invalid-result`, an early CLI exit uses `process`, and unrecognized values or exceptions use `unknown` without copying the value.

-| Stage | Owned operation | Observable failure |
-| --- | --- | --- |
-| `query-start` | SDK query construction, native platform-payload startup, and unpublished rollback | `start()` rejects with fixed safe facts and any process outcome observed before rollback |
-| `query-run` | Published SDK message iteration and strict terminal-result validation | The run resolves as `error` with `limit`, `product-error`, `invalid-result`, or `unknown` |
-| `process` | Managed CLI exits before the SDK supplies a terminal result | The run resolves as `error` with `process` and the available exit code and signal |
-| `teardown` | Query close and managed process-tree release | `dispose()` rejects independently with fixed safe facts after cleanup still reaches its final exit wait |
+The [minimal-diagnostics decision](../simplification/2026-08-21-product-subagent-minimal-diagnostics.md) exclusively owns Claude Code categories, stages, process facts, permission ordering, and verification for Agent SDK 0.3.237 and Claude Code 2.1.237.

-The parent can distinguish coarse Claude Code limits, product failures, invalid results, process exits, and unknown failures while Codex still distinguishes its current budget, usage, service, policy, request, connection, stream, rollback, sandbox, and active-turn categories. Neither receives raw product text, and foreground and background scheduling preserve the same fact because both consume one `SubagentResult`.
+The parent can distinguish the current Codex budget, usage, service, policy, request, connection, stream, rollback, sandbox, and active-turn categories without receiving raw product text.

Foreground and background scheduling preserve the same fact because both consume one `SubagentResult`.
 
 The diagnostic is display text rather than a new public protocol. Callers may present it but must not branch on its punctuation or product-private category names. A pinned product-version upgrade revalidates the Provider mapping and evidence without requiring every official error member to remain model-visible.

 ## Claude Code provider
 
-`@deepseek-ai/dsh-subagent-claude-code` registers a Profile-selected provider name that defaults to `claude-code` and invokes `@anthropic-ai/claude-agent-sdk@0.3.237`. The provider omits `pathToClaudeCodeExecutable`, so the SDK selects Claude Code 2.1.237 from the matching OS, CPU, and Linux-libc platform package in its own optional dependency closure. The provider does not resolve or fall back to a host `claude`; an omitted, unsupported, missing, or damaged platform payload fails the first delegation at the SDK startup boundary. The provider uses the official `query()` entrypoint and passes the SDK's native `claude` or `claude.exe` command, arguments, cwd, environment, and forwarded signal from `spawnClaudeCodeProcess` to `dsh-subprocess`; its private `SpawnedProcess` adapter exposes only the stream, event, kill, and exit facts the SDK requires.

 The public configuration contains a non-empty `providerName`, an optional non-empty `model`, an explicit `env` overlay, a positive finite `disposeGraceMs` no greater than the repository's shared `MAX_TIMER_DELAY_MS`, and a five-value native `permissionMode` that defaults to `dontAsk`. Each named instance retains those resolved values for its own runs. An explicit model is passed unchanged through `Options.model`; omission leaves that field absent so native settings choose the model. Each run creates its own `AbortController`, sets `persistSession: false`, disables `AskUserQuestion`, and passes the resolved mode to the SDK; only `bypassPermissions` receives the SDK's explicit dangerous confirmation. The provider deliberately omits `settingSources`, so the SDK reads the host's normal user, project, and local Claude settings relative to the parent Session cwd. It neither copies nor filters those settings and does not create or modify login state. Remaining permission prompts are denied, MCP elicitation is declined, and blocking dialogs fail closed instead of waiting for a user interface the provider does not own.

 The Claude Code credentialed e2e maps the key and fixed official endpoint only in the provider's in-memory environment, uses the documented `deepseek-v4-pro[1m]` and `deepseek-v4-flash` model variables, and traverses the production provider, official SDK, and real CLI. It compares the trimmed result with a random nonce and proves whole-tree exit without calling the Messages API directly from the test.

 公开配置包含非空的 `providerName`、可选的非空 `model`、显式的 `env` 覆盖项、须为正有限值且不得大于仓库共享 `MAX_TIMER_DELAY_MS` 的 `disposeGraceMs`，以及默认使用 `dontAsk` 的五值原生 `permissionMode`。每个命名实例会为自己的运行保留这些已解析值。显式模型会原样传入 `Options.model`；省略时不设置该字段，由原生设置选择模型。每次运行都会创建自己的 `AbortController`，设置 `persistSession: false`、禁用 `AskUserQuestion`，并把已解析模式传给 SDK；只有 `bypassPermissions` 会取得 SDK 的显式危险确认。提供方故意省略 `settingSources`，因此 SDK 会相对于父会话 cwd 读取宿主机常规的用户、项目和本地 Claude 设置。它既不复制也不过滤这些设置，也不会创建或修改登录状态。其余权限提示会被拒绝，MCP elicitation 会被拒绝，阻塞对话会快速失败，而不会等待本提供方不负责的用户界面。

-Package tests pin both Bundle manifests, published patches, exact self-provider rows, and product runtime dependencies. Claude coverage pins Agent SDK 0.3.237, Claude Code 2.1.237, all eight platform packages, SDK-selected execution, and missing-payload failure without host fallback. Codex coverage pins wrapper 0.147.0, all six platform aliases, package-declared execution, native descendant quiescence, and the same missing-payload behavior. Workspace validation derives each published patch from its Bundle declaration rather than a package catalog. Package/base assertions plus actual pnpm production evidence prove the default and selected-product dependency boundaries, while real Bundle-patch and Agent-Preset composition covers none, either product, both, the tool-grant intersection, later-Session adoption, and zero startup processes.

The provider does not inspect `PATH`, implement platform selection, or fall back to a host `claude`. A configured `model` is a direct SDK override owned by the Provider instance; the provider does not discover model names, rewrite aliases, or set a fallback, and omission preserves native model selection. Native settings and authentication remain authoritative for every other product choice. The plugin does not create a product home, log in, or probe an account. Credential-shaped ambient variables are removed before the explicit `env` overlay is applied, so an API key or token intended for the child must be supplied there. Non-credential endpoint variables such as `ANTHROPIC_BASE_URL`, along with ordinary ambient values such as `PATH` and `HOME`, remain inherited unless overridden; `PATH` does not choose the Claude executable.

 This package is an optional Profile Bundle. Install it into the target Profile, then restart that Profile; installation brings the pinned Agent SDK and one compatible platform CLI payload into that Profile, while the declared `cordis.patch.yml` layer registers only the dormant `claude-code` Host provider and starts no Claude process. Removing the package withdraws that provider and its private runtime closure on the next Profile start.

 ## Product compatibility and evidence
 
-The runtime dependency is pinned to `@anthropic-ai/claude-agent-sdk@0.3.237`, whose eight platform packages carry Claude Code 2.1.237. A normal install selects one payload for the current OS, CPU, and Linux libc. For the current darwin-arm64 payload, `npm pack --dry-run --json` reports 88,589,191 packed bytes and 317,110,872 unpacked bytes; other platforms may differ, and these values are disclosure rather than an installation threshold. The keyless real-product test runs the SDK-selected CLI against a loopback Messages fixture and asserts that the shared subprocess argv begins with that platform package's native executable. It also proves that an omitted model comes from native settings and two named instances send their distinct configured models. Loader composition proves that installing the Bundle registers only dormant Claude Code providers and starts no product process.

Loader composition proves that installing the Bundle registers only dormant Claude Code providers and starts no product process.
 
 Installing with optional dependencies omitted, using an unsupported platform, or losing the selected payload leaves provider registration dormant but makes the first delegation fail at the SDK startup boundary. The caller receives the safe `query-start` / `unknown` failure fact; the native payload error remains only on the internal cause chain and in the Provider's Host log. The provider neither probes a host CLI nor retries with one.

 如果安装时省略 optional dependencies、当前平台不受支持，或所选载荷缺失，提供方注册仍保持休眠，但第一次委派会在 SDK 启动边界失败。调用方只会收到安全的 `query-start` / `unknown` 失败事实；原生载荷错误只保留在内部 cause 链和提供方 Host 日志中。提供方既不会探测宿主 CLI，也不会用它重试。

 Product providers remain process-scoped host-plane registrations. The [production-install exclusion decision](../simplification/2026-08-12-production-dsh-excludes-product-subagent-providers.md) supersedes only this note's former base-bundle installation choice: production `dsh-base` neither depends on nor mounts them. A Profile that opts in installs the selected provider Bundle; its patch mounts the default instance, and the Profile may mount additional named instances on the host plane. The [named-instance decision](../feature/2026-08-18-product-subagent-named-instances.md) owns each row's registry identity: both products accept multiple unique `providerName` values while preserving `codex` and `claude-code` as their defaults. Loading either plugin only registers a dormant backend; the corresponding Codex or Claude process starts on the first actual delegation call. Agent Presets independently contribute ordinary `dsh-tool-subagent` rows whose `provider` and `toolName` values expose exactly the configured instances needed by one agent without changing the Host registry.
 
-Each provider package owns its directly installable Bundle patch and private product runtime. This note continues to own process-wide Host placement whenever either provider is installed. The provider-contract note continues to own each product protocol, result mapping, cancellation, process-tree lifecycle, and evidence tiers. The [named-instance decision](../feature/2026-08-18-product-subagent-named-instances.md) owns the optional Claude Code model and other per-instance configuration. The [Agent Preset architecture](2026-08-03-per-session-agent-presets.md) continues to own the Host/Agent split, preset authoring, and the rule that edits affect only newly composed sessions.

The wrapper selects the private native platform payload; the provider neither resolves nor falls back to a host `codex`. Its public configuration contains a non-empty `providerName`, an explicit `env` overlay, a positive finite `disposeGraceMs` no greater than the repository's shared `MAX_TIMER_DELAY_MS`, and a three-value native `permissionMode` that defaults to `never`. Each named instance retains those resolved values for its own runs. Installation, login, `CODEX_HOME`, model selection, base URL, and product-session settings remain native Codex or deployment responsibilities; the selected mode owns only the thread approval/reviewer/sandbox fields described by the non-interactive permissions decision.

-For command and file approvals, the unattended wire selects a non-approval decision offered by the request, preferring `cancel`; the stable 0.147.0 request shape without an offered-decision list falls back to `decline`. It grants no requested permissions for the turn, answers user-input requests with no answers, and declines MCP elicitation. It records safe categories for those requests, declined command/file items, and `sandboxError`. Codex emits some early `never` rejections and sandbox violations only on structured stderr, so the Provider pipes and forwards stderr unchanged while matching two fixed signatures in a bounded per-run tail; raw stderr never enters the diagnostic. A request with no legal unattended response, or any unknown server request, fails the run instead of waiting for a user interface the provider does not supply.

 An unpublished startup failure closes the wire, terminates the acquired process tree, waits for exit, detaches the stderr observer, and then rejects `start()` with its fixed operation stage. Published disposal best-effort interrupts a known turn, closes the wire, ends stdin, invokes the shared termination escalation, waits for whole-tree exit, and detaches the observer. Independent cleanup failure reports `teardown`; when startup and rollback both fail, the aggregate's top message retains both safe stage lines while the underlying causes remain internal.

 Each product owns branch-complete package tests, a required keyless real-product spec, a Loader composition e2e, and a credentialed DeepSeek e2e. The keyless product tier uses the exact official distribution under test, a non-empty fake product key, an isolated temporary workspace and product home, and a loopback fixed-answer model. Missing product requests, wrong authentication, altered task text, a non-exact answer, a skipped real product, or a surviving managed handle fails the required test. The Codex Loader fixture exposes two named Codex instances and tools; the Claude Code Loader fixture exposes the default Codex tool plus two named Claude Code instances and tools. Both fixtures include generic Job controls and start neither product process. The credentialed tier starts the same production provider and real product with a runtime-only key, requires a unique nonce from the fixed official DeepSeek service, and proves quiescence again; it self-skips only when a local operator supplied no key, while trusted CI preflights the secret.

 ## Problem
 
-A Profile can mount one Cordis plugin package in multiple rows, but the Codex and Claude Code product providers previously registered every row under one fixed product name. A second row therefore failed as a duplicate before its distinct model where supported, permission mode, environment, or process-release settings could become usable. Deriving an implicit name from those settings would create a second identity rule, while choosing a provider during a tool call would let model input select deployment authority.
+A Profile can mount one Cordis plugin package in multiple rows, but the Codex and Claude Code product providers previously registered every row under one fixed product name. A second row therefore failed as a duplicate before its distinct model, permission mode, environment, or process-release settings could become usable. Deriving an implicit name from those settings would create a second identity rule, while choosing a provider during a tool call would let model input select deployment authority.
 
 The existing subagent registry already owns unique provider names, reversible registration, lifecycle events, and holder-owned published runs. The existing `dsh-tool-subagent` configuration already binds one provider name to one model-visible tool name. Product providers need to expose the missing Profile-owned identity without adding another registry or selection protocol.
 
 ## Decision
 
-Each product provider Config owns a non-empty `providerName`; the defaults remain `codex` and `claude-code`. The resolved name is fixed when the plugin row loads and becomes the Provider object's `name`; registration, lookup, lifecycle events, run logs, and HMR removal therefore use the same value. Each mounted row retains its own `permissionMode`, `env`, `disposeGraceMs`, and run resources. Claude Code rows also retain an optional non-empty `model`; an explicit value is fixed for every query from that instance, while omission leaves native settings authoritative.

Each mounted row retains its own optional non-empty `model`, `permissionMode`, `env`, `disposeGraceMs`, and run resources. An explicit model is fixed for every query or thread from that instance, while omission leaves the native product settings authoritative.
 
 Profiles may mount multiple Codex or Claude Code rows when every row uses a distinct `providerName`. Each `dsh-tool-subagent` row continues to bind its existing `provider` field to that exact name and exposes an independently configured `toolName`. Tool calls carry no provider selector, alias, or permission input. A duplicate provider name fails through the existing `DUPLICATE_PROVIDER` path and leaves the first registration intact.
 
-Removing one provider row blocks new starts and removes only tools bound to that name. Runs already published by the removed instance remain owned by their holders and settle or dispose independently. Sibling instances remain registered and keep their own configured model where supported, environment, native permission mode, cancellation controller, product process, and cleanup grace.

 ## Consequences
 
-A Profile can expose several Codex and Claude Code tools backed by separate native permission modes and environments, and Claude Code instances may additionally fix separate models, while existing configurations continue to resolve `codex` and `claude-code`. Provider and tool names remain independent configuration facts, so changing one requires updating the binding that refers to it.

 The design adds no runtime renaming, model-visible provider or model selector, generated tool name, persistent instance directory, shared process pool, model discovery, fallback, or compatibility alias. Correct multi-instance configurations require unique provider names and unique tool names; duplicate tool-name waiting remains a separate limitation.

 现有 subagent 注册表已经拥有提供方名称唯一性、可逆注册、生命周期事件和由持有方拥有的已发布运行。现有 `dsh-tool-subagent` 配置也已经把一个提供方名称绑定到一个模型可见工具名称。产品提供方只需公开缺失的 Profile 所有身份，无需增加另一套注册表或选择协议。
 
 ## 决策
 
-每个产品提供方 Config 都拥有非空的 `providerName`；默认值仍分别为 `codex` 与 `claude-code`。插件配置项加载时会固定解析后的名称，并把它作为 Provider 对象的 `name`；注册、查找、生命周期事件、运行日志和 HMR（热模块替换）移除因此使用同一个值。每个已挂载配置项保留自己的 `permissionMode`、`env`、`disposeGraceMs` 和运行资源。Claude Code 配置项还会保留可选的非空 `model`；显式值为该实例的每次 query 固定，省略时仍以原生设置为权威。

 当每个配置项使用不同的 `providerName` 时，Profile 可以挂载多个 Codex 或 Claude Code 配置项。每个 `dsh-tool-subagent` 配置项继续用已有的 `provider` 字段绑定这个准确名称，并公开独立配置的 `toolName`。工具调用不携带提供方选择器、别名或权限输入。重复提供方名称沿用现有 `DUPLICATE_PROVIDER` 路径失败，而且不会替换第一个注册项。
 
-移除一个提供方配置项会阻止新的启动，并且只移除绑定到该名称的工具。该实例已经发布的运行仍由其持有方拥有，并会独立结算或 dispose（资源释放）。兄弟实例继续保持注册，并保留各自支持时配置的模型、环境、原生权限模式、取消控制器、产品进程和清理宽限期。

 ## Start and ownership
 
-`start(request)` accepts only a non-empty sequence of text blocks and derives the child cwd from the parent Session. It then spawns the fixed command through [`dsh-subprocess`](../../subprocess/subprocess/README.md), performs `initialize` → `initialized`, maps the Profile-selected mode into official `thread/start` approval/reviewer/sandbox fields beside `{ cwd, ephemeral: true }`, and publishes the run only after Codex returns a valid ephemeral thread. A failure or cancellation before publication closes the wire, terminates the managed process tree, waits for it to exit, and rejects `start()`. Non-cancellation rejections expose only the fixed `initialize` or `thread-start` stage plus an already observed process outcome; raw product and Host errors remain on internal cause chains.
+`start(request)` accepts only a non-empty sequence of text blocks and derives the child cwd from the parent Session. It then spawns the fixed command through [`dsh-subprocess`](../../subprocess/subprocess/README.md), performs `initialize` → `initialized`, maps the Profile-selected mode and optional model into official `thread/start` fields beside `{ cwd, ephemeral: true }`, and publishes the run only after Codex returns a valid ephemeral thread. A failure or cancellation before publication closes the wire, terminates the managed process tree, waits for it to exit, and rejects `start()`. Non-cancellation rejections expose only the fixed `initialize` or `thread-start` stage plus an already observed process outcome; raw product and Host errors remain on internal cause chains.
 
 The published `run.result` starts exactly one turn. It accepts only notifications for that run's thread and turn, then waits for the authoritative `turn/completed` terminal notification. The latest `agentMessage` with `phase: "final_answer"` wins; when Codex emits no explicit final phase, the latest message with `phase: null` is the compatibility fallback. Commentary never replaces either answer, and a successful turn with no nonblank answer settles as an error.
 
-For command and file approvals, the unattended provider selects a non-approval decision offered by the request, preferring `cancel`; the stable 0.147.0 request shape without an offered-decision list falls back to `decline`. It answers permission requests with an empty turn-scoped permission set, answers user-input requests with no answers, and declines MCP elicitation. A request with no legal unattended response, or any unknown server request, fails the run. The wire records only the effective mode, request category, decision, and fixed safe reason. It also recognizes declined command/file items and `sandboxError` terminals. Codex 0.147.0 writes some early `never` rejections and sandbox violations only to structured stderr, so the Provider pipes stderr, forwards it unchanged to the host, and matches two fixed signatures in a bounded per-run tail; raw stderr never enters the diagnostic.

A request with no legal unattended response, or any unknown server request, fails the run. The wire records only the effective mode, request category, decision, and fixed safe reason. It also recognizes declined command/file items and structured `sandboxError` terminals. Product stderr is forwarded unchanged to the Host but is never classified or copied into the diagnostic.
 
-Local cancellation wins the result race and maps to `aborted`. For failed turns, the diagnostic preserves all eleven string and five object variants in the Codex 0.147.0 `codexErrorInfo` union; the four connection/stream variants retain a numeric `httpStatusCode` when supplied, while `activeTurnNotSteerable` does not expose `turnKind`. The diagnostic also names `turn-start`, `turn`, or `process`, independently includes available exit code and signal, and uses `unknown` for unrecognized or malformed values without copying raw fields. `contextWindowExceeded` remains `max-tokens`; every other remote interruption or failure remains `error`, and the provider produces no `refusal`. A contributing permission decision follows the structured failure line. Successful and locally cancelled runs omit both facts.
+Local cancellation wins the result race and maps to `aborted`. Failed turns use the coarse categories `limit`, `access-policy`, `service`, `transport`, `product-error`, `invalid-result`, or `unknown`; an early app-server exit uses `process`.

A contributing structured permission decision follows the failure line. Successful and locally cancelled runs omit both facts.
 
 `dispose()` is idempotent: it requests a best-effort `turn/interrupt` with both current ids when they are known, closes the JSON-RPC wire, ends stdin, invokes the shared process-tree termination escalation, waits for whole-tree exit, and detaches the stderr observer. Independent cleanup rejection uses the fixed `teardown` stage and any available process outcome. When startup and rollback both fail, the top-level aggregate message preserves both safe stage lines while the raw failures remain internal.

The keyless real-product test drives the package wrapper against a loopback Responses fixture and observes the package-local argv, exact Bearer key, original task, byte-exact final answer, thread-level `never` overriding ambient `on-request`, automatic-review startup, unattended rejection without file side effects, a real `internalServerError`, explicit dangerous-bypass writing in suite-owned temporary storage, process/protocol failure with safe exit facts, and wrapper/native quiescence. The same tier proves two named instances retain separate environments and native modes.
+Generated schema evidence pins the optional `ThreadStartParams.model` field, while package tests cover representative error groups, applicable HTTP status, six lifecycle stages, process outcomes, stop-reason mapping, unknown fallback, sanitization, structured permission ordering, cancellation, concurrency, and cleanup aggregation. The keyless real-product test drives the package wrapper against a loopback Responses fixture and observes the package-local argv, omitted-model inheritance, two explicit instance models, exact Bearer key, original task, byte-exact final answer, thread-level `never` overriding ambient `on-request`, automatic-review startup, unattended rejection without file side effects, a real service failure, explicit dangerous-bypass writing in suite-owned temporary storage, process/protocol failure with safe exit facts, and wrapper/native quiescence.
 
 Installing with optional dependencies omitted, using an unsupported platform, or losing the selected payload makes the first delegation fail at `initialize` with the safe `unknown` category and any observed process outcome.

 ## Known Limitations and Deferred Work
 
 - **One fresh process, thread, and turn per run** — there is no continuation, resume, pooling, progress stream, or product-session persistence.
-- **Static instance selection** — Profile rows fix provider names and tool bindings; calls cannot choose a provider dynamically, and every exposed tool needs a unique `toolName`.
+- **Static instance selection** — Profile rows fix provider names, optional models, and tool bindings; calls cannot choose or change either a provider or model dynamically, and every exposed tool needs a unique `toolName`.
 - **Authentication and account state remain native** — the Bundle supplies the CLI but does not create an account, log in, trust a project, or rewrite Codex settings; configuration and authentication failures surface with their lifecycle stage and the safe `unknown` fallback rather than a separate public taxonomy.
 - **The native platform payload is required at delegation time** — installs that omit optional dependencies, unsupported platforms, and missing or damaged payloads fail at the first run; there is no host-CLI fallback.
-- **Compatibility is pinned by development evidence** — upgrading from the verified 0.147.0 protocol baseline requires regenerating upstream schema evidence and rerunning handshake, answer-selection, approval, cancellation, keyless real-product, and credentialed DeepSeek nonce tests.
+- **Compatibility is pinned by development evidence** — upgrading from the verified 0.148.0 protocol baseline requires regenerating upstream schema evidence and rerunning handshake, answer-selection, approval, cancellation, keyless real-product, and credentialed DeepSeek nonce tests.
 - **No human approval path** — known unattended approval requests are denied and unknown server requests fail closed; the three Profile modes never create a DSH interaction channel or per-call allow policy.
 - **Assistant payload is final text only** — a failed run may additionally expose the separate safe diagnostic; reasoning, commentary, intermediate messages, tool traffic, usage, raw stderr, and workspace diffs remain outside the parent Session, while generic Job ids, notices, and status come from the shared job runtime.
 - **No optional shared capabilities** — `agentOptions`, output schemas, child personas, tool filtering, and harness depth enforcement are rejected by the shared service for this provider.

 已发布的 `run.result` 恰好启动一个轮次。它只接受与此次运行的线程和轮次匹配的通知，随后等待权威的终止通知 `turn/completed`。以最后一条 `phase: "final_answer"` 的 `agentMessage` 为准；若 Codex 没有发出明确的最终阶段，则以最后一条 `phase: null` 的消息作为兼容性回退。过程说明绝不会取代上述任一答案；成功完成的轮次若没有非空白答案，结果也会判为错误。
 
-对于命令与文件审批，无人值守的提供方会从请求给出的决策选项中选择一项不予批准的决策，并优先选择 `cancel`；稳定的 0.147.0 请求形态没有决策选项列表，因此回退到 `decline`。它对权限请求返回作用域限于当前轮次的空权限集，不向用户输入请求提供任何答案，并拒绝 MCP elicitation。若请求在无人值守模式下没有合法响应，或是未知服务器请求，此次运行就会失败。wire 只记录有效模式、请求类别、决定与固定的安全原因，也会识别被拒绝的命令／文件 item 和 `sandboxError` 终态。Codex 0.147.0 的部分早期 `never` 拒绝和 sandbox violation 只写入结构化 stderr，因此提供方会 pipe stderr、原样转发给 Host，并在每次运行的有界尾缓冲中匹配两个固定签名；原始 stderr 不会进入诊断。

-`@deepseek-ai/dsh-subagent-codex` registers a Profile-selected provider name that defaults to `codex`, resolves the `codex` bin declared by its pinned `@openai/codex@0.148.0` package, and starts that wrapper through the current Node executable with `app-server --stdio`. The wrapper selects the private native platform payload; the provider neither resolves nor falls back to a host `codex`. Its public configuration contains a non-empty `providerName`, an optional non-empty `model`, an explicit `env` overlay, a positive finite `disposeGraceMs` no greater than the repository's shared `MAX_TIMER_DELAY_MS`, and a three-value native `permissionMode` that defaults to `never`. Each named instance retains those resolved values for its own runs. An explicit model is passed unchanged on every ephemeral `thread/start`; omission leaves native Codex settings authoritative. Installation, login, `CODEX_HOME`, model discovery or fallback, base URL, and product-session settings remain native Codex or deployment responsibilities; the selected mode owns only the thread approval/reviewer/sandbox fields described by the non-interactive permissions decision.

Installation, login, `CODEX_HOME`, model discovery or fallback, base URL, and product-session settings remain native Codex or deployment responsibilities; the selected mode owns only the thread approval/reviewer/sandbox fields described by the non-interactive permissions decision.
 
 Before publication, the provider validates a non-empty text-only task, starts the managed app-server in the parent workspace, completes `initialize` → `initialized`, maps the optional model and resolved mode into official `thread/start` fields, and creates an `ephemeral: true` thread. The fixed app-server argv contains no model, mode, or task text. The published run owns exactly one `turn/start`; its thread and turn ids remain private and are never persisted in the parent Session.
 
 `turn/completed` is the authoritative remote terminal fact. The latest `agentMessage` with `phase: "final_answer"` wins, and that selected message must contain nonblank text. When the product emits no explicit final phase, the latest message with `phase: null` is the compatibility fallback and must likewise be nonblank; commentary never replaces either answer. The [minimal-diagnostics decision](../simplification/2026-08-21-product-subagent-minimal-diagnostics.md) owns Codex action categories, HTTP status, lifecycle stages, process outcomes, and stop-reason preservation. Local cancellation remains `aborted` without a failure diagnostic.
 
-For command and file approvals, the unattended wire selects a non-approval decision offered by the request, preferring `cancel`; the stable 0.148.0 request shape without an offered-decision list falls back to `decline`. It grants no requested permissions for the turn, answers user-input requests with no answers, and declines MCP elicitation. It records safe categories for those requests, declined command/file items, and structured `sandboxError` terminals. Product stderr is forwarded unchanged to the Host but is neither classified nor copied into the diagnostic. A request with no legal unattended response, or any unknown server request, fails the run instead of waiting for a user interface the provider does not supply.

 An unpublished startup failure closes the wire, terminates the acquired process tree, waits for exit, detaches the stderr observer, and then rejects `start()` with its fixed operation stage. Published disposal best-effort interrupts a known turn, closes the wire, ends stdin, invokes the shared termination escalation, waits for whole-tree exit, and detaches the observer. Independent cleanup failure reports `teardown`; when startup and rollback both fail, the aggregate's top message retains both safe stage lines while the underlying causes remain internal.
 
-Codex 0.148.0 speaks the Responses protocol, while DeepSeek's public OpenAI-compatible endpoint speaks Chat Completions. The credentialed Codex e2e therefore uses a loopback-only, test-private bridge for one no-tool nonce request: real Codex sends Responses to the bridge, the bridge forwards the received bearer credential and extracted task to the fixed official DeepSeek endpoint, and it wraps the real text in the minimal Responses SSE lifecycle. The bridge is neither a production proxy nor evidence that Codex connects to DeepSeek Chat Completions natively.

 Each product owns branch-complete package tests, a required keyless real-product spec, a Loader composition e2e, and a credentialed DeepSeek e2e. The keyless product tier uses the exact official distribution under test, a non-empty fake product key, an isolated temporary workspace and product home, and a loopback fixed-answer model. Missing product requests, wrong authentication, altered task text, a non-exact answer, a skipped real product, or a surviving managed handle fails the required test. The Codex Loader fixture exposes two named Codex instances and tools; the Claude Code Loader fixture exposes the default Codex tool plus two named Claude Code instances and tools. Both fixtures include generic Job controls and start neither product process. The credentialed tier starts the same production provider and real product with a runtime-only key, requires a unique nonce from the fixed official DeepSeek service, and proves quiescence again; it self-skips only when a local operator supplied no key, while trusted CI preflights the secret.
 
-The Codex evidence pins `@openai/codex@0.148.0`, `codex-cli 0.148.0`, and all six optional platform aliases. Its generated schema proves optional `ThreadStartParams.model`; the real-product spec observes omitted-model inheritance, two explicit instance models, the package-local wrapper argv, exact Bearer key, original task, byte-exact final answer, native permission modes, explicit dangerous-bypass writing in suite-owned temporary storage, and wrapper/native whole-tree exit. An isolated wrapper fixture proves missing-payload failure without host fallback, named instances retain separate models, environments, and modes, and production never resolves a host `codex` from `PATH`. The [minimal-diagnostics decision](../simplification/2026-08-21-product-subagent-minimal-diagnostics.md) owns failure, process-outcome, and final presentation evidence.

It fixes the external endpoint and model, stores no credential or request payload, requires exactly one completed upstream response, compares the trimmed product answer byte-for-byte with the nonce, and waits for every managed handle to exit.

 `turn/completed` 是权威的远端终止事实。以最后一条带有 `phase: "final_answer"` 的 `agentMessage` 为准，且选中的消息必须包含非空白文本。若产品没有发出明确的最终阶段，则以最后一条 `phase: null` 的消息作为兼容性回退，该消息也必须包含非空白文本；过程说明绝不会取代上述任一答案。[最小诊断决策](../simplification/2026-08-21-product-subagent-minimal-diagnostics.zh.md)负责 Codex 行动类别、HTTP status、生命周期阶段、进程结果与终止原因保持。本地取消仍是 `aborted` 且不附带失败诊断。

 Post-boot profile watcher setup proceeds only while the root fiber and Loader are both live. A concurrent setup error is contained only when the same invocation's recorded signal already owns shutdown; unrelated HMR failures remain loud. The [process-shutdown controller](../bug-fix/2026-08-03-cli-signal-shutdown-escalation.md) lets a successful one-shot completion drain Node's remaining handles after root disposal, while teardown failure, deadline, and signal escalation retain forced exit. The vendored Include serializes debounced writes, retries only transient access or busy failures with bounded backoff, and observes every timer rejection. A terminal persistence failure remains on the queue and is rethrown to the teardown owner, while successful teardown drains the latest write.

 The published `run.result` starts exactly one turn. It accepts only notifications for that run's thread and turn, then waits for the authoritative `turn/completed` terminal notification. The latest `agentMessage` with `phase: "final_answer"` wins; when Codex emits no explicit final phase, the latest message with `phase: null` is the compatibility fallback. Commentary never replaces either answer, and a successful turn with no nonblank answer settles as an error.

It answers permission requests with an empty turn-scoped permission set, answers user-input requests with no answers, and declines MCP elicitation. A request with no legal unattended response, or any unknown server request, fails the run. The wire records only the effective mode, request category, decision, and fixed safe reason. It also recognizes declined command/file items and structured `sandboxError` terminals. Product stderr is forwarded unchanged to the Host but is never classified or copied into the diagnostic.

 Local cancellation wins the result race and maps to `aborted`. Failed turns use the coarse categories `limit`, `access-policy`, `service`, `transport`, `product-error`, `invalid-result`, or `unknown`; an early app-server exit uses `process`. Applicable connection and stream failures retain a numeric `httpStatusCode`. The diagnostic also names `turn-start`, `turn`, or `process` and independently includes available exit code and signal without copying raw fields. `contextWindowExceeded` remains `max-tokens`; every other remote interruption or failure remains `error`, and the provider produces no `refusal`. A contributing structured permission decision follows the failure line. Successful and locally cancelled runs omit both facts.

 This package is an optional Profile Bundle.

Removing the package withdraws that provider and its private runtime closure on the next Profile start.

Closes #2848.

- dsh-llm 新增 LlmAdapter.imageRequestPricing 同步钩子与 LlmImageRequestPricing/LlmImageRequestPrice 词汇，ctx.llm 按路由解析
- llm-deepseek 用官方公布的 v4 视觉计算器逐句移植（14px patch、3:1 降采样、384 上限、最坏对齐 pad）实现该钩子，复现请求投影的最旧优先 offload 与像素预算缩放；纯几何 requestImageDimensions 上移到 dsh-attachment
- token-meter 表层 fold 存储与路由无关的节点事实，measure() 按生效 envelope 的路由为图片出现处定价；锚点存快照并按同一路由重定价；TokenSurfaceNode 同时携带路由价 tokens 与固定启发式 heuristicTokens
- compaction 触发、保留与选段读取同一套路由价，记录的 shadowedTokenCount 保持启发式以维持 O(1) 投影 fold 一致
- llm-replay 支持按模型的 imageRequestTokens 声明；新增 keyless 的 image-compaction ACP 快照场景端到端验证装配应用

+
+## Problem
+
+The token meter priced an `ImageBlock` as the structural JSON of its durable reference — roughly forty tokens — while a DeepSeek request image costs up to 384 visual tokens, so an image-dense session could carry hundreds of thousands of unbilled estimated tokens. Provider usage anchors only completed requests: the first multimodal request, images added after the anchor, and offload-set changes all fed automatic compaction a pressure figure that was wrong by orders of magnitude, triggering it far too late (context overflow) or, after a route change, too early. The [version-one simplification](../simplification/2026-07-29-simplify-web-image-input-v1.md) had deliberately rejected a provider-neutral tile formula and deferred visual pricing until a provider-aware estimator had a concrete consumer.
+
+## Decision
+
+Compaction pressure is now priced by the routed model's own request projection. `LlmAdapter.imageRequestPricing(provider, model)` is an optional synchronous hook returning an `LlmImageRequestPricing` for one exact route, resolved through `ctx.llm.imageRequestPricing()`; the base adapter declares none and unknown providers degrade to `undefined`, never throw. Each ordered image occurrence resolves to an `LlmImageRequestPrice`: the provider's visual tokens for a retained image plus the model-visible text the wire actually carries (request-preview handle, offload placeholder, or text-only substitution), with the text left to the caller's own estimator so no provider fixes a text tokenization.
+
+The DeepSeek adapter implements the hook from its connection snapshot (`request-pricing.ts`): uncatalogued and text-only models price every occurrence as its `textOnlyImageText` substitution; image-capable models reproduce the serializer's first-stage oldest-first offload through the shared `offloadedImagePrefixCount()` and price retained images at their `requestImageDimensions` projection with `deepSeekImageTokens()` — a verbatim port of the provider's published v4 vision calculator (14px patches, 3:1 downsampling, 384-token cap, minimum-pixel scale-up, 8:1 width clamp), priced at the worst-case pad-to-4 alignment. The pure geometry moved from `attachment-local` to `dsh-attachment` so provider and pricing share it.
+
+The token meter's surface fold stores route-neutral facts per node — the fixed-heuristic price, the image-free price, and the durable image occurrences — and `measure()` prices the surface under the effective envelope's route on every call. The anchor holds its raw materials (surface snapshot, provider-output price, usage) instead of a precomputed baseline, so a matching header reprices both the anchor and the current surface under one route and the signed delta compares like with like; the usage-versus-estimated choice happens per measurement against the route-priced anchor. Public `TokenSurfaceNode` carries both `tokens` (route-priced; read by trigger, retention, and range selection) and `heuristicTokens` (fixed; the shadow-price protocol's unit, so `compaction/summary` and `compaction/prune` stay consistent with the O(1) projection fold's own appends). The `contextPressure` and `contextBreakdown` projections deliberately stay on the fixed heuristic.
+
+The test-support replay adapter declares a flat per-model `imageRequestTokens` so keyless assembled scenarios exercise the seam; the `image-compaction` ACP snapshot proves six inline images push the second turn's pre-step measurement over an automatic threshold that the text-only heuristic stays under, and that the triggered compaction shadows the image message at its heuristic price.
+
+## Alternatives considered
+
+**Price images inside the provider-neutral estimator.** Rejected by the [version-one note](../simplification/2026-07-29-simplify-web-image-input-v1.md) and still wrong: visual pricing varies by provider, model, detail mode, and preprocessing, and a hard-coded figure would look authoritative on routes it does not describe. The hook keeps every constant in the adapter that owns the route.
+
+**Correct pressure only from provider usage.** Usage cannot price the first multimodal request, an image added after the anchor, or a changed offload set — exactly the cases that made compaction fire too late. Usage stays the anchor for completed requests; the route projection prices the increment.
+
+**Reproduce the full serialization pipeline, including prepared-version bytes and the base64 fallback budgets.** The second-stage offload depends on encoded request bytes that only exist after asynchronous image preparation. The pricing reproduces the deterministic first stage from durable byte lengths; a fallback request can only offload more and cost less, so the estimate stays conservative without I/O in a synchronous hook.
+
+**Route-price the shadow-price protocol too.** Logged `shadowedTokenCount` feeds the O(1) projection fold, whose appends are priced by the fixed heuristic; pricing replacements by route would make the persisted running total drift. Keeping the protocol on `heuristicTokens` preserves the fold's by-construction agreement.
+
+**Fold route pricing into the meter's replay state.** A fold keyed to one route would have to replay on every route change and could not answer a `requestHeader` override for a different model. Storing route-neutral node facts and pricing at `measure()` keeps replay single-pass and measurement O(surface), which the contract already promises.
+
+## Consequences
+
+Automatic compaction now triggers on the pressure the routed model's next request will actually carry: image-dense DeepSeek sessions compact before overflow instead of after it, text-only routes charge substitution text instead of phantom visual tokens, and offloaded images cost their placeholder. The worst-case alignment pad overprices an image by at most three tokens, and the unreproduced base64-fallback budgets can only overprice — both errors are conservative, and provider usage remains the authoritative anchor once a request completes. The published v4 calculator constants live in `llm-deepseek` alone; if the provider revises its vision projection, that one module and its pinned vectors are the change site. Measurement cost gains one pricing resolution and one image-occurrence walk per call, still O(surface).
+
+## Testing
+
+Formula vectors in `image-tokens.spec.ts` pin the published calculator's outputs, including the aspect-clamp, scale-up floor, one-column solver, odd-grid trim, and second-pass convergence cases, cross-checked against the reference implementation over a dimension grid and 50,000-point fuzz during development. `request-pricing.spec.ts` covers text-only substitution, the low-detail preset, and count- and byte-driven offload boundaries. Token-meter specs cover the first multimodal estimate, post-anchor image deltas over usage, text-only repricing under a header override, pricer-less neutrality, occurrence-count mismatch, and nested tool-result images. Compaction specs prove trigger, retention, and range selection read the route price while the logged shadow price stays heuristic. The keyless `image-compaction` ACP snapshot exercises the assembled application end to end.

+# Agent Note: 按路由定价的图片请求压力
+
+Status: implemented
+
+[English](2026-08-24-route-priced-image-request-pressure.md) | 中文
+
+## Problem
+
+token 计量服务把 `ImageBlock` 按其持久引用的 JSON 结构计价，约四十个 token，而一张 DeepSeek 请求图片最多消耗 384 个视觉 token，因此图片密集的会话可能携带数十万个未计入估算的 token。provider usage 只锚定已完成的请求：首次多模态请求、锚点之后新增的图片、offload 集合的变化，都会让自动 compaction 拿到数量级错误的压力值，触发得过晚（上下文溢出）或在路由切换后过早。[版本一简化](../simplification/2026-07-29-simplify-web-image-input-v1.zh.md)曾有意否决 provider-neutral 的 tile 公式，把视觉定价推迟到 provider-aware 估算器出现具体消费方之时。
+
+## Decision
+
+compaction 压力现在按路由模型自身的请求投影定价。`LlmAdapter.imageRequestPricing(provider, model)` 是可选的同步钩子，为一条确切路由返回 `LlmImageRequestPricing`，经 `ctx.llm.imageRequestPricing()` 解析；基类不声明定价，未注册的 provider 降级为 `undefined` 而绝不抛出。每个按序的图片出现处解析为一个 `LlmImageRequestPrice`：保留图片的提供方视觉 token，加上线上实际携带的模型可见文本（请求预览句柄、offload 占位文本或纯文本替换），文本交由调用方自己的估算器计价，避免任何提供方固定一种文本 token 化。
+
+DeepSeek 适配器基于连接快照实现该钩子（`request-pricing.ts`）：未编目和纯文本模型把每个出现处按其 `textOnlyImageText` 替换计价；支持图片的模型通过共享的 `offloadedImagePrefixCount()` 复现序列化器第一阶段的最旧优先 offload，并按 `requestImageDimensions` 投影尺寸用 `deepSeekImageTokens()` 为保留图片计价，后者是提供方公布的 v4 视觉计算器的逐句移植（14px patch、3:1 降采样、384 token 上限、最小像素放大、8:1 宽度钳制），按最坏的 pad-to-4 对齐计价。纯几何函数从 `attachment-local` 上移到 `dsh-attachment`，供提供方与定价共享。
+
+token 计量服务的表层 fold 为每个节点存储与路由无关的事实：固定启发式价格、去图价格与持久图片出现处；`measure()` 在每次调用时按生效 envelope 的路由为表层定价。锚点保存原始材料（表层快照、提供方输出价格、usage）而非预先计算的基线，因此匹配的标头会把锚点与当前表层放在同一路由下重新定价，带符号 delta 的比较口径一致；usage 与估算的选择在每次计量时针对路由定价锚点做出。公开的 `TokenSurfaceNode` 同时携带 `tokens`（路由定价；触发、保留与选段读取它）和 `heuristicTokens`（固定值；影子价协议的计量单位，使 `compaction/summary` 与 `compaction/prune` 与 O(1) 投影 fold 自身的追加保持一致）。`contextPressure` 与 `contextBreakdown` 投影有意保持固定启发式规则。
+
+test-support 的回放适配器按模型声明固定的 `imageRequestTokens`，让 keyless 装配场景走通这条 seam；`image-compaction` ACP 快照证明六张内联图片把第二轮 pre-step 计量推过自动阈值，而纯文本启发式保持在阈值之下，且被触发的 compaction 按启发式价格遮蔽了图片消息。
+
+## Alternatives considered
+
+**在 provider-neutral 估算器里为图片定价。** 已被[版本一 note](../simplification/2026-07-29-simplify-web-image-input-v1.zh.md)否决且依然错误：视觉定价随提供方、模型、细节档位与预处理而不同，写死的数字在它不描述的路由上会显得权威却错误。钩子把每个常量留在拥有该路由的适配器里。
+
+**只用 provider usage 校正压力。** usage 无法为首次多模态请求、锚点后新增图片或变化的 offload 集合定价，而这些正是让 compaction 触发过晚的情形。usage 仍是已完成请求的锚点；增量由路由投影定价。
+
+**复现完整序列化管线，包括请求版本字节与 base64 回退预算。** 第二阶段 offload 依赖异步图片准备之后才存在的编码字节。定价复现由持久字节长度决定的确定性第一阶段；回退请求只会 offload 更多、花费更少，因此估算在同步无 I/O 的钩子里保持保守。
+
+**让影子价协议也按路由定价。** 记录的 `shadowedTokenCount` 供 O(1) 投影 fold 消费，而该 fold 的追加按固定启发式计价；替换若按路由定价会让持久化的累计值漂移。协议保持在 `heuristicTokens` 上，维持 fold 的构造性一致。
+
+**把路由定价并入计量服务的回放状态。** 绑定单一路由的 fold 在路由每次变化时都得重放，也无法回答指向另一模型的 `requestHeader` 覆盖。存储与路由无关的节点事实并在 `measure()` 时定价，保持单遍回放与契约已承诺的 O(surface) 计量。
+
+## Consequences
+
+自动 compaction 现在按路由模型下一次请求实际携带的压力触发：图片密集的 DeepSeek 会话在溢出之前而非之后压缩，纯文本路由收取替换文本而非幻影视觉 token，被 offload 的图片按占位文本计费。最坏对齐 pad 对单图最多多计三个 token，未复现的 base64 回退预算只会多计——两种误差都偏保守，请求完成后 provider usage 仍是权威锚点。公布的 v4 计算器常量只存在于 `llm-deepseek`；提供方若修订其视觉投影，改动点就是这一个模块与其钉死的向量。每次计量多一次定价解析与一次图片出现处遍历，仍为 O(surface)。
+
+## Testing
+
+`image-tokens.spec.ts` 的公式向量钉死公布计算器的输出，覆盖宽高比钳制、放大下限、单列求解、奇数网格裁剪与第二遍收敛的用例，开发期间与参考实现在尺寸网格及五万点模糊测试上对拍。`request-pricing.spec.ts` 覆盖纯文本替换、低细节预设以及数量与字节驱动的 offload 边界。token-meter 测试覆盖首次多模态估算、usage 之上的锚后图片 delta、标头覆盖下的纯文本重定价、无定价器时的中性行为、出现处数量不匹配与嵌套工具结果图片。compaction 测试证明触发、保留与选段读取路由价格而记录的影子价保持启发式。keyless 的 `image-compaction` ACP 快照端到端验证装配后的应用。

 The durable attachment seam. `ctx.attachments` validates and durably commits a provider-independent normalized image, then returns a serializable `ImageAttachmentRef`; consumers never persist browser paths, object URLs, provider URLs, local storage paths, or base64 in session events.
 
-Unsent composer images remain browser-owned temporary drafts. `validateImage` runs the complete admission policy without persisting. `saveImages` owns batch count and aggregate-byte limits, prepares every normalized attachment before publishing any member, then commits in order and returns references only after the complete batch succeeds. A later storage failure returns no partial references, although an earlier immutable content-addressed object may remain unreachable until reference-aware garbage collection exists. `AttachmentError.code` uses the closed `AttachmentErrorCode` string union. Its `ImageAdmissionErrorCode` subset marks caller-correctable image-input failures; `isImageAdmissionError` recognizes that subset at runtime so each protocol adapter can map its own error vocabulary. `saveImage` commits one accepted image before any model-visible session event is published and returns its `ImageAttachmentRef`. When normalization reduces the raster, the reference records the orientation-applied input size in `originalDimensions`. `readImage` verifies the normalized attachment against its logged metadata. `readImageRequest` deterministically derives a route-sized request version whose identity covers the attachment id, transform version, pixel and byte budgets, and encoder settings. `imageHostPath` optionally exposes the provider-owned object's absolute host path; it makes no claim that the current model tools can read that path. An LLM consumer combines this location with the mounted filesystem's execution-world mapping when it serializes a request. That current access path remains separate from the request version and its `variantId`. Callers compose ordered batches with `Promise.all(refs.map(...))`; the local implementation still bounds compression through its instance limiter, cache, and singleflight. Callers may cancel reads and projections; implementations preserve cancellation instead of translating it into a storage failure.

The pure `requestImageDimensions` export computes that projection's aspect-preserving dimensions from a total-pixel budget, so providers and request pricing share one geometry. `imageHostPath` optionally exposes the provider-owned object's absolute host path; it makes no claim that the current model tools can read that path. An LLM consumer combines this location with the mounted filesystem's execution-world mapping when it serializes a request.

Callers may cancel reads and projections; implementations preserve cancellation instead of translating it into a storage failure.
 
 `admitEncodedImages(attachments, images)` is the shared wire entry used by every RPC endpoint that accepts browser uploads (the session prompt endpoint and the command executor): it enforces canonical base64 on every member, then delegates batch admission — limits, validation, ordered commit — to `saveImages`. The base64 upload form is `EncodedImageAttachment`, exported from `@deepseek-ai/dsh-attachment/types` so wire contracts can reference it.

+- **Measurement** — the singleton `ctx.tokenMeter` prices the latest canonical logged envelope and current surface at one consumed-log revision, under the routed model's declared request-image pricing when its adapter declares one. Step-boundary pressure therefore includes the actual system prompt, tools, routing, assistant completion, tool results, buffered context, steering, and route-priced image history; trigger, recent-tail retention, and range selection all read the same per-node prices, while the logged shadow price of a replaced range stays on the route-independent fixed heuristic so pure projection folds remain consistent.
 - **Routed policy** — proactive pressure resolves capacity from the adapter that owns the latest durable provider/model route, then scales the default policy plus an optional exact-target override into concrete token budgets. Model discovery remains advisory and is not consulted.
 - **Model-free pruning** — after pressure or canonical overflow qualifies, the optional [`ctx.toolResultPruner`](../compaction-tool-result-pruner/README.md) service rewrites oversized tool results before range selection. Compact-basic remeasures through `ctx.tokenMeter`, skips summarization when pressure becomes safe, and otherwise summarizes the pruned surface. Below-pressure step checks never prune.
 - **Retention** — compact the oldest whole surface units while preserving a recent tail and balanced tool-call/result cuts through the [`dsh-compaction` boundary helpers](../compaction/README.md#tool-pairing-boundaries). Turn boundaries do not protect old steps inside a runaway turn. An open indivisible tail declines until it closes. The optional pruner can repair an oversized closed tool unit when its text-bearing result is the removable bulk; indivisible non-tool units and non-prunable tool remainders remain out of scope.

 ## Known Limitations and Deferred Work

+- **Meter accuracy follows the fixed heuristic** — missing reusable provider usage falls back to character count plus structural overhead rather than exact tokenization; image occurrences carry provider-exact visual tokens only on routes whose adapter declares request-image pricing.
 - **Overflow classification is adapter-maintained** — provider wording can change; both DeepSeek adapters normalize currently recognized context-limit failures to `CONTEXT_WINDOW_EXCEEDED`.
 - **Some indivisible-unit and envelope-only overflow remains outside surface compaction** — recovery cannot shrink system/tools/prefix, split an indivisible non-tool node, or repair a tool unit whose non-prunable remainder still exceeds the window. The optional pruner can shrink text-bearing tool-result bulk inside an otherwise indivisible pair.
 - **`compactRegion` requires an open turn** — a manual call on a fully-closed session throws ("no open turn") rather than compacting.

-Provider tokenization governs exact text and image-token input. Reasoning passback carries every reasoned turn's chain of thought into later requests, while dropping over-budget images avoids paying those tokens again; cache-read usage is reported when available.
+Provider tokenization governs exact text and image-token input. The adapter additionally declares per-route request-image pricing (`imageRequestPricing`): it reproduces the request projection's oldest-first offload from durable byte lengths and prices each retained image with the published v4 vision accounting (14px patch grid, 3:1 downsampling, 384-token cap, worst-case alignment pad) at its projected request dimensions, so the token meter can price image pressure before a request is sent; reported usage remains authoritative. Reasoning passback carries every reasoned turn's chain of thought into later requests, while dropping over-budget images avoids paying those tokens again; cache-read usage is reported when available.

 Message content is an array of typed blocks: `text`, `reasoning`, `image`, `tool-call`, `tool-result`. An `ImageBlock` carries only a durable `ImageAttachmentRef`; provider bytes and request dimensions are resolved later. The union remains merge-extensible through `ContentBlockMap`, so plugins can add further block types via declaration merging. Assistant messages use a model source carrying the provider and model that produced them plus optional adapter-private replay state. Before dispatch, `LlmRuntime` retains that state only when the historical provider route and target provider route are currently owned by the exact same adapter instance; the adapter then decides whether it can restore or convert the state across models/providers.
 
-Every dispatch uses the exact model modalities captured with its adapter generation. An image-capable adapter projects durable image references into route-specific request versions. `resolveImageAttachmentAccess()` separately combines an attachment provider's optional host object with a consumer-supplied mapping from that host path into the current tool execution world. The result never enters `RequestImageAttachment` or its `variantId`. A text-only route instead receives deterministic attachment placeholders, including nested tool-result images, without changing append-only session history. `offloadRequestImagesWithPolicy()` provides deterministic oldest-first image removal with raw or base64 accounting and count or byte quanta; adapters supply the exact derived-version byte length and the required per-image placeholder text.

Adapters whose provider charges visual tokens declare per-route `imageRequestPricing`; `ctx.llm.imageRequestPricing(provider, model)` resolves it synchronously for the token meter.
 
 Streaming is a raw chunk protocol (`block-start`, `text-delta`, `reasoning-delta`, `tool-call-delta`, `block-end`, `usage`, `finish`). Every adapter outcome reaches consumers as one terminal `finish`; operational failure uses its `error` or `aborted` reason rather than throwing across the stream API. `BlockAssembler` is the single shared implementation that assembles chunks into blocks/messages. A successful `finish` may carry a `ReplayEnvelope` — opaque response-level replay metadata plus optional per-block entries aligned with the emitted block sequence. Assembly makes one keep/drop decision for content and metadata together: a `max-tokens` finish drops tool calls that may have been truncated, and the envelope loses the entry at each dropped position, so stored metadata always describes stored content.

An explicit empty `sourceEventSeqs` list means a known empty provider stream, while an absent legacy list conservatively treats the durable assistant output as provider output.

+- **The fixed heuristic is approximate** — text without reusable provider usage is priced by character count plus structural overhead, not an exact provider tokenizer or request serializer; only image occurrences on routes with declared pricing carry provider-exact visual tokens.
 - **Every measurement clones the current surface** — coherent immutable snapshots make reads O(surface), including below-threshold pressure checks.
 - **Provider usage is only reusable for an identical canonical envelope** — prompt, prefix, tools, provider, model, or call-config changes deliberately fall back to full heuristic estimation.
 - **Missing legacy source seqs are handled conservatively** — assistant messages without `sourceEventSeqs` cannot distinguish provider output from listener rewrites, so the fold avoids claiming a known empty or exact chunk stream.

 Compaction pressure is now priced by the routed model's own request projection. `LlmAdapter.imageRequestPricing(provider, model)` is an optional synchronous hook returning an `LlmImageRequestPricing` for one exact route, resolved through `ctx.llm.imageRequestPricing()`; the base adapter declares none and unknown providers degrade to `undefined`, never throw. Each ordered image occurrence resolves to an `LlmImageRequestPrice`: the provider's visual tokens for a retained image plus the model-visible text the wire actually carries (request-preview handle, offload placeholder, or text-only substitution), with the text left to the caller's own estimator so no provider fixes a text tokenization.
 
-The DeepSeek adapter implements the hook from its connection snapshot (`request-pricing.ts`): uncatalogued and text-only models price every occurrence as its `textOnlyImageText` substitution; image-capable models reproduce the serializer's first-stage oldest-first offload through the shared `offloadedImagePrefixCount()` and price retained images at their `requestImageDimensions` projection with `deepSeekImageTokens()` — a verbatim port of the provider's published v4 vision calculator (14px patches, 3:1 downsampling, 384-token cap, minimum-pixel scale-up, 8:1 width clamp), priced at the worst-case pad-to-4 alignment. The pure geometry moved from `attachment-local` to `dsh-attachment` so provider and pricing share it.

-The token meter's surface fold stores route-neutral facts per node — the fixed-heuristic price, the image-free price, and the durable image occurrences — and `measure()` prices the surface under the effective envelope's route on every call. The anchor holds its raw materials (surface snapshot, provider-output price, usage) instead of a precomputed baseline, so a matching header reprices both the anchor and the current surface under one route and the signed delta compares like with like; the usage-versus-estimated choice happens per measurement against the route-priced anchor. Public `TokenSurfaceNode` carries both `tokens` (route-priced; read by trigger, retention, and range selection) and `heuristicTokens` (fixed; the shadow-price protocol's unit, so `compaction/summary` and `compaction/prune` stay consistent with the O(1) projection fold's own appends). The `contextPressure` and `contextBreakdown` projections deliberately stay on the fixed heuristic.

 ## Consequences
 
-Automatic compaction now triggers on the pressure the routed model's next request will actually carry: image-dense DeepSeek sessions compact before overflow instead of after it, text-only routes charge substitution text instead of phantom visual tokens, and offloaded images cost their placeholder. The worst-case alignment pad overprices an image by at most three tokens, and the unreproduced base64-fallback budgets can only overprice — both errors are conservative, and provider usage remains the authoritative anchor once a request completes. The published v4 calculator constants live in `llm-deepseek` alone; if the provider revises its vision projection, that one module and its pinned vectors are the change site. Measurement cost gains one pricing resolution and one image-occurrence walk per call, still O(surface).

 ## Testing
 
-Formula vectors in `image-tokens.spec.ts` pin the published calculator's outputs, including the aspect-clamp, scale-up floor, one-column solver, odd-grid trim, and second-pass convergence cases, cross-checked against the reference implementation over a dimension grid and 50,000-point fuzz during development. `request-pricing.spec.ts` covers text-only substitution, the low-detail preset, and count- and byte-driven offload boundaries. Token-meter specs cover the first multimodal estimate, post-anchor image deltas over usage, text-only repricing under a header override, pricer-less neutrality, occurrence-count mismatch, and nested tool-result images. Compaction specs prove trigger, retention, and range selection read the route price while the logged shadow price stays heuristic. The keyless `image-compaction` ACP snapshot exercises the assembled application end to end.

 - **Routed policy** — proactive pressure resolves capacity from the adapter that owns the latest durable provider/model route, then scales the default policy plus an optional exact-target override into concrete token budgets. Model discovery remains advisory and is not consulted.
 - **Model-free pruning** — after pressure or canonical overflow qualifies, the optional [`ctx.toolResultPruner`](../compaction-tool-result-pruner/README.md) service rewrites oversized tool results before range selection. Compact-basic remeasures through `ctx.tokenMeter`, skips summarization when pressure becomes safe, and otherwise summarizes the pruned surface. Below-pressure step checks never prune.
 - **Retention** — compact the oldest whole surface units while preserving a recent tail and balanced tool-call/result cuts through the [`dsh-compaction` boundary helpers](../compaction/README.md#tool-pairing-boundaries). Turn boundaries do not protect old steps inside a runaway turn. An open indivisible tail declines until it closes. The optional pruner can repair an oversized closed tool unit when its text-bearing result is the removable bulk; indivisible non-tool units and non-prunable tool remainders remain out of scope.

That last case is why the field exists: compaction summarizes through a direct `ctx.llm.stream()` call and appends no usage of its own, so `pressureTokens` alone reports the pre-compaction prompt until an entire further turn completes.

 Three packages, layered exactly like the existing Python stack, plus one Service Provider registration:
 
-- **`@deepseek-ai/dsh-sdk-protocol`** (`packages/sdk/protocol/`) — the wire made shared and nominal. `JsonRpcLineTransport` moves here verbatim from `dsh-sdk-jsonrpc-server` (which now imports it), and `types.ts` names every payload the server speaks: `InitializeParams/Result`, `SessionPromptParams/Result`, the four notification payloads, and the `HarnessSdkRequestMap`/`HarnessSdkNotificationMap` indexes. The package root explicitly exports that complete interface and provides no source-module deep imports. The server's `notify()` call sites are typed against these named payloads, so server drift breaks compilation, not clients. One behavioral change: an error response now rejects with `JsonRpcResponseError` carrying the wire `code`/`data` (the Python client already preserved these; the old transport threw a bare `Error` with only the message).
-- **`@deepseek-ai/dsh-sdk-client`** (`packages/sdk/client/`) — the TypeScript twin of `python/sdk`: `HarnessClient` (spawn, frame, fan out notifications, typed error surfaces, close-to-quiescence via the shared dispose ladder) under `DeepSeekHarness`/`HarnessSession` (lazy start, memoized `initialize`, `run()` pairing one `session/prompt` with its `session.finished`). Its package-root consumer interface explicitly exports both client layers, caller-facing types, and the protocol-owned `JsonRpcResponseError`; source modules, normalization helpers, and the notification producer stay internal. `RunResult.events` contains only the root session's typed events, while `notifications` retains session ids across the root and descendants discovered from `subagent.started`; session-tree scoping is client-side, mirroring `client.py`. The launch interface resolves the same-version `@deepseek-ai/dsh` dependency and selects a named profile, with optional `dshBin`, ordered patches, an explicit Harness home, process cwd, environment, and timeouts; arbitrary command/argv launch remains an internal fake-runtime adapter. A clean checkout without `lib/bin.js` uses that package's source entry through an absolute `tsx/esm` loader and an internal patch that omits build-generated Typert contribution loading, which the SDK protocol does not consume. `env` replaces rather than merges and is read when `start()` spawns, so callers own credential policy and can finish preparing it before first use. `RunResult` carries the structured `reason` (Python exposes only `status`); teardown walks a private stdin-EOF → SIGTERM → SIGKILL ladder to actual exit (the client runs outside any harness context, so it cannot ride `ctx.subprocess`).
-- **`@deepseek-ai/dsh-subagent-dsh-sdk`** (`packages/subagent/subagent-dsh-sdk/`) — the second out-of-process `SubagentProvider`, structured as `subagent-acp`'s sibling: same all-false capabilities and `inheritsParentContext: false`, same publish-after-handshake ownership transaction, same result-never-rejects flattening through an `onError` sink, same parent-namespace run id. The child answer is read from streamed `session.event`s — the last complete `assistant/message`, else accumulated `text-delta` chunks, so partial answers survive cancellation. Stop reasons map from the child's structured `TurnEndReason` (`completed`/`max-tokens`/`aborted` pass through; everything else, including a settled-without-turn child, is `error`). Its `dshBin`/profile/patch/home config selects an isolated SDK application, `provider`/`model` feeds the child's `initialize`, and `env` supplies explicit child-only values such as its API key.
+- **`@deepseek-ai/dsh-sdk-protocol`** (`packages/sdk/protocol/`) — the wire made shared and nominal. `JsonRpcLineTransport` lives here, and `types.ts` names every payload the server speaks: `InitializeParams/Result`, `SessionPromptParams/Result`, the four notification payloads, and the `HarnessSdkRequestMap`/`HarnessSdkNotificationMap` indexes. `InitializeParams` carries provider, model, optional adapter-owned reasoning effort, and optional output cap. The package root explicitly exports that complete interface and provides no source-module deep imports. The server's `notify()` call sites are typed against these named payloads, so server drift breaks compilation, not clients. Error responses reject with `JsonRpcResponseError` carrying the wire `code`/`data`, matching the Python client.

Its package-root consumer interface explicitly exports both client layers, caller-facing types, and the protocol-owned `JsonRpcResponseError`; source modules, normalization helpers, and the notification producer stay internal. `RunResult.events` contains only the root session's typed events, while `notifications` retains session ids across the root and descendants discovered from `subagent.started`; session-tree scoping is client-side, mirroring `client.py`.

Other start capabilities remain false, and `inheritsParentContext: false`. The provider retains the same publish-after-handshake ownership transaction, result-never-rejects flattening through an `onError` sink, and parent-namespace run id. The child answer is read from streamed `session.event`s — the last complete `assistant/message`, else accumulated `text-delta` chunks, so partial answers survive cancellation.

Process mechanics (spawn, env scrub, tree-scoped teardown) live in the `dsh-subprocess` seam; `subagent-acp` spawns through `ctx.subprocess`, while this backend spawns through the SDK client (the subprocess README's documented exception for SDK-managed transports) and applies the seam's `scrubbedParentEnv()` itself.

+`dsh-sdk-jsonrpc-server` validates the exact provider/model/effort route during `initialize`, stores only explicitly supplied effort and token values, and creates every SDK root Agent from that fixed process-wide route. TypeScript and Python clients both expose the same initialization fields through `dsh --profile sdk`; the Python wheel packages that CLI and its closed dependency tree.
 
 ## Testing
 
 Four tiers, per [testing policy](../../../../docs/testing.md):
 
 - **Keyless unit** — `sdk-client` drives a scripted fake runtime (`tests/fake-runtime.ts`, env-scripted, protocol-only — the Python `test_client.py` pattern) over real stdio; `subagent-dsh-sdk` drives the same fake through the real provider. 100% per-file coverage on all three packages.
-- **Keyless Loader composition** — `subagent-dsh-sdk/tests/loader-composition.e2e.ts` boots a test-only cordis.yml (`examples/python-sdk-agent/tests/fixtures/subagent/subagent-dsh-sdk/`) where the child is a real second `dsh --profile sdk` runtime with its own isolated home and ordered patch; asserts the parent tool result and the child's own persisted transcript both carry the parent session's cwd.
-- **Keyless snapshot** — `examples/python-sdk-agent/tests/sdk.snapshot.ts` drives the real `dsh --profile sdk` runtime through the real `dsh-sdk-client`, replaying recorded fixtures through an ordered `llm-replay` patch. Four scenarios — text turn, bash tool, spawn subagent, and the minimal persistent-tool composition — each pin the normalized notification stream, SDK turn result, and persisted parent and child logs. This also closes the protocol-tier gap the single-exe note's Python-side snapshot left on the vitest side.
+- **Keyless Loader composition** — `subagent-dsh-sdk/tests/loader-composition.e2e.ts` boots a test-only cordis.yml (`examples/python-sdk-agent/tests/fixtures/subagent/subagent-dsh-sdk/`) where the child is a real second `dsh --profile sdk` runtime with its own isolated home and ordered patch; it asserts provider/model/reasoning/maxTokens and parent cwd in both the tool result and the child's persisted request header.
+- **Keyless snapshot** — `examples/python-sdk-agent/tests/sdk.snapshot.ts` drives the real `dsh --profile sdk` runtime through the real `dsh-sdk-client`. Text, bash, and in-process subagent scenarios replay recorded fixtures through `llm-replay`; the DSH SDK scenario uses deterministic parent and child adapters to pin a model-selected route through the delegation tool, a second SDK runtime, and the child's persisted request header. The minimal persistent-tool scenario covers the smaller shipped profile. Every scenario pins the normalized notification stream, SDK result, and applicable session logs.
 - **With-key e2e** — the snapshot suite's `DSH_SNAPSHOT=record` mode is the live-API path (it produced the committed fixtures); the composition e2e needs no key by design.

+The dsh process starts lazily on first use and stays owned across `run()` calls. `close()` (or `await using`) is required. `start()` memoizes the bounded `initialize` handshake, which carries the workspace cwd, provider/model route, optional adapter-owned `reasoningEffort`, and optional positive `maxTokens` output cap. `initializeTimeoutMs` defaults to 10 seconds, and its diagnostic names the selected profile with the retained stderr tail. The server validates the exact route before accepting prompts; omitting the effort preserves the model's own default. A failed handshake reaps the runtime and lets a later call retry with a fresh process until terminal `close()`. The cap applies to each root-agent request and is inherited by in-process descendants; compaction plugins own their separate summary limits. `session(id?)` opens a named or fresh session handle.
 
-The handshake carries the absolute session workspace plus provider/model and optional positive `maxTokens`. `run(input, { sessionId?, onNotification? })` queues a prompt, waits for its durable inbox receipt, and collects until the whole root agent next becomes idle. It returns `RunResult { sessionId, finalResponse, events, notifications }`; `events` is root-scoped, while notifications also contain discovered descendants.

+`start(request)` resolves the child's working directory and one process-wide SDK route before spawning. Each declared `request.agentOptions` field (`provider`, `model`, `reasoningEffort`, or `maxTokens`) overrides the matching provider-instance default; omission preserves the configured provider/model and optional cap, while reasoning effort remains omitted unless the request supplies it. The provider then spawns through `DeepSeekHarness` and completes the child runtime's `initialize` handshake, including exact-model and effort validation, before it fulfills. Fulfillment therefore means the child runtime is ready and ownership has transferred to the caller. A route, spawn, handshake, or pre-publication cancellation failure rejects only after the subprocess has been reaped; a working-directory resolution failure rejects before anything is spawned.
 
 The working directory resolves exactly like the ACP backend, through the seam's shared out-of-process helpers ([`dsh-subagent`](../subagent/README.md)): the configured `cwd` override when set (validated once at load), else the delegating parent session's cwd — never the server process's own cwd. The resolved path becomes the child process cwd and the workspace cwd of its SDK session. `dshHome` is separately required as an absolute path so a nested runtime cannot accidentally share its parent's profiles, plugin installation, or session storage.

 ## Known Limitations and Deferred Work
 
 - **A fresh runtime process per run** — no pooling; a harness runtime boots a full plugin tree, so per-run spawn cost is higher than the ACP backend's typical child.
-- **No optional start-time capabilities** — the parent cannot apply `agentOptions` or enforce `outputSchema`, depth, tool filters, or persona inside the child process; configure the selected child profile and its ordered patches instead.
+- **No non-route start-time capabilities** — the parent can select the child Agent route but cannot enforce `outputSchema`, depth, tool filters, or persona inside the child process; configure the selected child profile and its ordered patches instead.
 - **The child's transcript stays in the child's own session root** — the parent log records only the delegation tool call/result (the seam's child-isolation rule); the streamed `session.event` channel is consumed for output extraction, not bridged into the parent log.
 - **Local child processes only** — the resolved cwd is a local path; a remote runtime would need its own backend.

Initialization rejects a missing adapter, unavailable model, or unsupported effort before a prompt runs. Compaction summaries keep the separate limit configured by their compaction plugin. The bundled default composition registers `deepseek-official`. A custom composition can mount `llm-pi-ai`, configure provider-specific credentials/endpoints there, and select any provider/model present in pi-ai's installed catalog.

 The shipped `sdk-minimal` profile is a standalone explicit tree rather than an overlay on `dsh-base`.

+An explicit or configured provider, model, or effort first passes through the bound provider's optional synchronous default resolver, then resolves through `ctx.llm.resolveCallConfig()` before child creation. The same resolved Agent options are passed to `start()`, so parent preflight and provider execution cannot choose different routes.

The tool checks cancellation again after the asynchronous lookup and before creating a child or background job. Calls with no model-facing selection and no configured route fields preserve the existing provider path without requiring the optional LLM service.
 
 An enabled definition registers `list_subagent_models`. With no arguments the tool lists registered providers; with `provider` it calls that adapter's advisory model catalog; with `provider` and `model` it resolves the exact model and returns its reasoning efforts and default. At most one instance in a tool scope enables selection because the discovery name is global. Shipped product compositions put `modelSelectionSettings: true` on the primary Agent-scoped `subagent` instance and register the Host-owned `subagent-model-selection` settings namespace with `enabled: false`. A new top-level Session samples that preference during composition and logs an enabled decision as `subagent/model-selection-enabled` before any model request. A child Session inherits the live parent's decision, and a resumed Session uses its existing marker instead of the current preference. Therefore a settings edit affects only subsequently composed top-level Sessions. The fixed discovery definition remains available without the optional LLM service, while discovery and selected-route calls fail until that service is present. An unlisted model remains selectable when the adapter accepts its id.

 The delegation definition is static across adapter registration and catalog changes, so live topology neither expands every parent request nor invalidates its cache prefix. The discovery result enters the transcript only when called. A custom inheritance-capable instance that enables selection warns that changing provider or model can prevent provider-side reuse of the inherited conversation prefix.

+Both in-process providers advertise `agentOptions`: child creation merges requested fields over the provider, model, and reasoning effort in the parent's latest logged request, falling back to its creation options before the first request and retaining its configured token limit. A route change without an explicit effort clears the inherited route-owned effort so the selected model resolves its default. DSH SDK also advertises the capability and implements `resolveAgentOptions()` so its provider/model/maxTokens instance defaults are materialized before the Consumer preflights the exact route; `start()` applies the same resolution for direct callers. ACP, Codex, and Claude Code advertise the capability as unsupported, so their transports reject configured or model-selected overrides instead of silently ignoring them.
 
 Every in-process child is composed by one call, `applyChildComposition(childCtx, parent, composition)`, which joins the parent's agent-preset composition before applying the child's own persona and tool filter. The join is what gives the child its capabilities: with every model-facing row on the agent plane, a child that joined nothing would reach the model with an empty tool registry ([`dsh-agent-presets`](../../preset/agent-presets/README.md)). Taking the parent as a parameter is deliberate — it makes composing a child WITHOUT that join unrepresentable at the call sites, which is the defect the one call exists to prevent. A deployment composing no preset roster joins nothing and needs nothing: its model-facing rows sit in the host composition, where the child already resolves them through the tool registry's global layer.

 每个进程内子 agent 都通过一次 `applyChildComposition(childCtx, parent, composition)` 调用完成组装：先加入父级的 agent-preset 组合，再应用子 agent 自己的 persona 和工具限制。加入父级组合正是子 agent 获得能力的途径：所有面向模型的行都位于 agent 平面，完全没有加入任何组合的子 agent 抵达模型时会看到空的工具注册表（见 [`dsh-agent-presets`](../../preset/agent-presets/README.zh.md)）。将父级作为参数是刻意设计：这让“组装子 agent 却不做该加入”在各调用点无法表达，而这正是这一次调用所要杜绝的缺陷。未组装 preset roster 的部署不加入任何组合、也不需要加入；其面向模型的行位于宿主组合中，子 agent 已能通过工具注册表的全局层解析到它们。

+Each plugin instance binds one subagent transport `provider` to one `toolName`; the model cannot change that transport.

A call may supply a complete provider/model pair, or only an effort when configured, parent, or provider-owned defaults supply the effective route. Model fields first override tool `agentOptions`; a provider with `resolveAgentOptions()` then materializes its own missing defaults before the live adapter preflights the exact route, and the same resolved value reaches `start()`. Providers without that hook retain compatible missing values from the parent's latest logged request selection, falling back to its creation options before the first request and retaining its configured `maxTokens`. Changing provider or model without naming an effort clears the lower layer's route-owned effort so the selected model resolves its default.
 
 The delegation tool registers only while its subagent provider exists, avoiding sibling load-order and provider-reload dependencies. When model selection is enabled, its optional fields remain visible without `ctx.llm`; a call that selects a route rejects if the service is unavailable. When disabled, the schema omits those fields and execution rejects a forced selection. Configured `agentOptions` remain deployment-owned child defaults independently of this model-facing switch. Adapter catalog and topology changes do not rewrite or re-register the tool. Its description follows `provider.inheritsParentContext`: fresh children require standalone prompts, while forked children already see completed parent turns.

No route allowlist is required. Registered LLM provider routes are available for child selection; this tool does not add a second authorization policy over the deployment's LLM registry.

+An explicit or configured provider, model, or effort resolves through `ctx.llm.resolveCallConfig()` after the provider baseline and request precedence are complete. Providers with static route defaults suppress parent-effort inheritance when the request omits effort, preserving the selected model's default. The LLM lookup owns provider registration, exact-model metadata, reasoning-effort validation, and adapter defaults. After the asynchronous lookup, the tool checks cancellation and confirms the same provider instance remains registered before creating a child or background job, so HMR cannot combine one provider's defaults with another provider's process. Calls with no model-facing selection and no configured route fields preserve the existing provider path without requiring the optional LLM service.
 
 An enabled definition registers `list_subagent_models`. With no arguments the tool lists registered providers; with `provider` it calls that adapter's advisory model catalog; with `provider` and `model` it resolves the exact model and returns its reasoning efforts and default. At most one instance in a tool scope enables selection because the discovery name is global. Shipped product compositions put `modelSelectionSettings: true` on the primary Agent-scoped `subagent` instance and register the Host-owned `subagent-model-selection` settings namespace with `enabled: false`. A new top-level Session samples that preference during composition and logs an enabled decision as `subagent/model-selection-enabled` before any model request. A child Session inherits the live parent's decision, and a resumed Session uses its existing marker instead of the current preference. Therefore a settings edit affects only subsequently composed top-level Sessions. The fixed discovery definition remains available without the optional LLM service, while discovery and selected-route calls fail until that service is present. An unlisted model remains selectable when the adapter accepts its id.

 The delegation definition is static across adapter registration and catalog changes, so live topology neither expands every parent request nor invalidates its cache prefix. The discovery result enters the transcript only when called. A custom inheritance-capable instance that enables selection warns that changing provider or model can prevent provider-side reuse of the inherited conversation prefix.
 
-`SubagentCapabilities.agentOptions` remains the transport truth. The service rejects a request carrying those options before calling a provider that advertises `false`. Both in-process providers and the DSH SDK transport advertise `true`; DSH SDK exposes its instance-default resolver, merges the four supported route fields once for tool preflight and direct starts, and validates the result during the new child runtime's `initialize`.

Tool configuration that supplies `agentOptions`, statically enables model selection, or makes it settings-controlled also fails when its bound provider lacks the capability.

A route change without an explicit effort clears the inherited route-owned effort so the selected model resolves its default.

ACP, Codex, and Claude Code advertise the capability as unsupported, so their transports reject configured or model-selected overrides instead of silently ignoring them.
 
 Every in-process child is composed by one call, `applyChildComposition(childCtx, parent, composition)`, which joins the parent's agent-preset composition before applying the child's own persona and tool filter. The join is what gives the child its capabilities: with every model-facing row on the agent plane, a child that joined nothing would reach the model with an empty tool registry ([`dsh-agent-presets`](../../preset/agent-presets/README.md)). Taking the parent as a parameter is deliberate — it makes composing a child WITHOUT that join unrepresentable at the call sites, which is the defect the one call exists to prevent. A deployment composing no preset roster joins nothing and needs nothing: its model-facing rows sit in the host composition, where the child already resolves them through the tool registry's global layer.

 每个进程内子 agent 都通过一次 `applyChildComposition(childCtx, parent, composition)` 调用完成组装：先加入父级的 agent-preset 组合，再应用子 agent 自己的 persona 和工具限制。加入父级组合正是子 agent 获得能力的途径：所有面向模型的行都位于 agent 平面，完全没有加入任何组合的子 agent 抵达模型时会看到空的工具注册表（见 [`dsh-agent-presets`](../../preset/agent-presets/README.zh.md)）。将父级作为参数是刻意设计：这让“组装子 agent 却不做该加入”在各调用点无法表达，而这正是这一次调用所要杜绝的缺陷。未组装 preset roster 的部署不加入任何组合、也不需要加入；其面向模型的行位于宿主组合中，子 agent 已能通过工具注册表的全局层解析到它们。

Changing provider or model without naming an effort clears the lower layer's route-owned effort so the selected model resolves its default.
 
 The delegation tool registers only while its subagent provider exists, avoiding sibling load-order and provider-reload dependencies. When model selection is enabled, its optional fields remain visible without `ctx.llm`; a call that selects a route rejects if the service is unavailable. When disabled, the schema omits those fields and execution rejects a forced selection. Configured `agentOptions` remain deployment-owned child defaults independently of this model-facing switch. Adapter catalog and topology changes do not rewrite or re-register the tool. Its description follows `provider.inheritsParentContext`: fresh children require standalone prompts, while forked children already see completed parent turns.

 `dsh-tool-subagent` exposes optional `provider`, `model`, and `reasoning_effort` fields only when its instance enables `enableModelSelection`, or its Agent-scoped `modelSelectionSettings` instance resolves an enabled Session decision, and the bound subagent provider advertises `SubagentCapabilities.agentOptions`. No route allowlist is required. Registered LLM provider routes are available for child selection; this tool does not add a second authorization policy over the deployment's LLM registry. Disabled instances omit and reject model-facing selection, while configured `Config.agentOptions` remain deployment-owned defaults. Either selection mode against a provider without the capability fails the plugin mount.
 
-Provider and model form one route and must be supplied together. An effort may be supplied alone when configured, parent, or provider-owned values provide the effective route. Static `provider.agentRouteDefaults`, when present, establish the provider/model/reasoning baseline; `Config.agentOptions` and model arguments overlay it before route-aware effort clearing. Providers without static defaults use compatible fields from the parent Agent's latest logged request selection, with creation options supplying the fallback before its first request and retaining the configured output-token limit. Reasoning-effort identifiers remain adapter-owned. An unchanged route inherits an omitted effort only from the selected baseline; changing provider or model without naming an effort clears the lower layer's route-owned value so the selected model resolves its own default. `AgentOptions` carries the resulting effort into the child loop, whose request header logs the effective value. A continuable descriptor records it with the resolved provider and model so a child that has not logged its first request can cold-resume with the same selection.

 An explicit or configured provider, model, or effort resolves through `ctx.llm.resolveCallConfig()` after the provider baseline and request precedence are complete. Providers with static route defaults suppress parent-effort inheritance when the request omits effort, preserving the selected model's default. The LLM lookup owns provider registration, exact-model metadata, reasoning-effort validation, and adapter defaults. After the asynchronous lookup, the tool checks cancellation and confirms the same provider instance remains registered before creating a child or background job, so HMR cannot combine one provider's defaults with another provider's process. Calls with no model-facing selection and no configured route fields preserve the existing provider path without requiring the optional LLM service.

 The delegation tool registers only while its subagent provider exists, avoiding sibling load-order and provider-reload dependencies. When model selection is enabled, its optional fields remain visible without `ctx.llm`; a call that selects a route rejects if the service is unavailable. When disabled, the schema omits those fields and execution rejects a forced selection. Configured `agentOptions` remain deployment-owned child defaults independently of this model-facing switch. Adapter catalog and topology changes do not rewrite or re-register the tool. Its description follows `provider.inheritsParentContext`: fresh children require standalone prompts, while forked children already see completed parent turns.

 委派工具只在其 subagent 提供方存在时注册，从而避免对同级加载顺序和提供方重新加载的依赖。启用模型选择时，即使没有 `ctx.llm`，可选字段仍然可见；选择路由的调用会在该服务缺失时失败。禁用时，schema 会省略这些字段，执行阶段也会拒绝强制传入的选择。配置的 `agentOptions` 仍是部署方所有的子级默认值，不受这个面向模型的开关影响。adapter 目录和拓扑变化不会改写或重新注册工具。工具描述遵循 `provider.inheritsParentContext`：新建子 agent（智能体）需要独立提示词，而 fork 子 agent 已能看到父级已完成轮次。

 - **`@deepseek-ai/dsh-subagent-dsh-sdk`** (`packages/subagent/subagent-dsh-sdk/`) — the second out-of-process `SubagentProvider`, structured as `subagent-acp`'s sibling but advertising `agentOptions: true`: each run merges provider/model/reasoning/maxTokens over instance defaults and sends only those fields through the child `initialize`. Other start capabilities remain false, and `inheritsParentContext: false`. The provider retains the same publish-after-handshake ownership transaction, result-never-rejects flattening through an `onError` sink, and parent-namespace run id. The child answer is read from streamed `session.event`s — the last complete `assistant/message`, else accumulated `text-delta` chunks, so partial answers survive cancellation. Stop reasons map from the child's structured `TurnEndReason` (`completed`/`max-tokens`/`aborted` pass through; everything else, including a settled-without-turn child, is `error`). Its `dshBin`/profile/patch/home config selects an isolated SDK application, while `env` supplies explicit child-only values such as its API key.
 - **The subagent seam grows `out-of-process.ts`**: the provider-side vocabulary both out-of-process backends share — `NO_START_CAPABILITIES`, timing-bound validation, child cwd resolution (config override, else the delegating parent session's workspace), the never-reject `settleRunResult`, and the `subprocessRunHandle` publication. Process mechanics (spawn, env scrub, tree-scoped teardown) live in the `dsh-subprocess` seam; `subagent-acp` spawns through `ctx.subprocess`, while this backend spawns through the SDK client (the subprocess README's documented exception for SDK-managed transports) and applies the seam's `scrubbedParentEnv()` itself.

Clients combine the open-ended `session.event` stream with agent-wide `session.status` according to their own activity ownership. `SubagentFinishedNotification.lastAssistantMessage` contains the child's last non-empty assistant message or, when no such message exists, its accumulated assistant text; the field is absent when the child produced neither. `InitializeParams.reasoningEffort` is an optional non-empty adapter-owned identifier for the selected provider/model route; omission preserves that model's own default. `InitializeParams.maxTokens` is an optional positive safe integer that caps each conversation-model output for SDK-created agents and their in-process descendants; omission allows the selected adapter's exact-model default to apply, or otherwise preserves provider behavior.

Clients combine the open-ended `session.event` stream with agent-wide `session.status` according to their own activity ownership. `SubagentFinishedNotification.lastAssistantMessage` contains the child's last non-empty assistant message or, when no such message exists, its accumulated assistant text; the field is absent when the child produced neither. `InitializeParams.reasoningEffort` is an optional non-empty adapter-owned identifier for the selected provider/model route; omission preserves that model's own default. `InitializeParams.maxTokens` is an optional positive safe integer that caps each conversation-model output for SDK-created agents and their in-process descendants; omission allows the selected adapter's exact-model default to apply, or otherwise preserves provider behavior. The server resolves the exact route during initialization and rejects `session/prompt` until that handshake succeeds, so a missing adapter, unavailable model, or unsupported effort cannot fall back to a prompt on constructor defaults.

 ## Wire notes
 
-`initialize` is the runtime-readiness boundary: when the server is mounted by a Loader composition, it waits for the current plugin tree to settle before replying, so async sibling capabilities such as initial MCP tool discovery are visible to the first prompt. Hand-built contexts without Loader remain immediately usable. `initialize.serverInfo.name` is the wire-stable `deepseek-harness-sdk-runtime`. The server validates the provider/model route and optional non-empty `reasoningEffort` through the selected adapter before storing them; omission stores no effort, so the model retains its own default. An optional positive `initialize.maxTokens` becomes the request output cap of each SDK-created agent and its in-process descendants; invalid values reject initialization, while omission sends no SDK cap and allows the selected adapter or provider route default to apply. `session/prompt` queues one identified user message and immediately returns `{ messageId }`. The server streams every durable fact as `session.event` and every whole-agent lifecycle transition as `session.status`; it does not assign an assistant message or `turn/end` to that prompt. Independent requests may enqueue more work on the same session. Persistence roots and persona come from the surrounding composition.

 Provider availability changes affect execution results and diagnostics, not whether the model-facing schema exists. If a product wants no web tools at all, it disables `dsh-tool-web` or the individual web tool in config; if it wants web tools but the backend is misconfigured, the model sees a structured tool error at execution time.

+The prompt guidance explains the semantic split — `web_search` for discovery and current information, `web_fetch` when the model needs the content of a specific URL — and the prompt and tool result tell the model to cite relevant URLs with markdown links. Every successful result labels provider-controlled text as external untrusted data. Fetch conversion removes active and hidden HTML content; unsafe conversion returns a fixed omission marker rather than raw HTML.
 
 The model-facing output is text-first because tool results are `ContentBlock[]`, but the seam outcome stays structured so UI presentation and future adapters do not have to scrape rendered text.

-The shipped web composition also mounts `dsh-web-fetch-approval-policy` on `tools/pre-execute`. `danger-full-access` delegates `web_fetch` without asking; `read-only` and `workspace-write` require one-shot approval after the HTTP provider's public-destination preflight; approval policy `never` denies without resolving or prompting. The preflight result only prevents an invalid question: the provider resolves again and pins the actual connection, so `allowed-once` cannot authorize a private destination or a later DNS-rebinding answer. Downstream `deny` and `ask` decisions remain authoritative. `plan` stays independent collaboration state, and products restrict plan work by composing it with a restricted sandbox preset rather than adding a second network-mode vocabulary.
+The shipped web composition also mounts `dsh-web-fetch-approval-policy` on `tools/pre-execute`. It evaluates downstream policies before a `web_fetch` decision. `danger-full-access` delegates without asking; `read-only` and `workspace-write` apply network-free URL syntax, length, credentials, and literal-IP checks before one-shot approval; approval policy `never` denies without resolving or prompting. After `allowed-once`, the provider resolves and pins the actual connection, rejects every non-public answer including private IPv4 reached through the active DNS64 prefix, and repeats enforcement at each same-origin redirect. The policy therefore leaks no hostname through DNS before consent, and a grant cannot authorize a private destination or DNS-rebinding answer. `plan` stays independent collaboration state, and products restrict plan work by composing it with a restricted sandbox preset rather than adding a second network-mode vocabulary.
 
 `createApiProxy` owns the approval pending registry. Its `approval/request` waterfall answerer reads the approval id from the session's just-appended `approval/asked` audit event (an ask with no audit event is a foreign channel and delegates), mints one stable rpcId per question, broadcasts the answerable `approval/requested` frame to every open mux stream, and replays still-pending frames verbatim on each mux open — the refresh-recovery baseline the contract already promised. `respond` routes by the echoed rpcId, validates `ApprovalResponsePayload` with the existing zod schema, cross-checks the payload's audit correlation against the routed entry, resolves the answerer, and broadcasts `approval/resolved`; the ask's abort signal withdraws the question as `cancelled`.

 ## Consequences
 
-Web sessions start confined (`workspace-write` + `ask` by default), `web_fetch` pauses for an answerable one-shot request only after a public-address preflight, and a sandbox-denial escalation reaches the browser through the same channel. The deployment can widen or narrow the default through `BootHostOptions.sandbox` without touching the assembly. Question answering uses the same registry pattern (ui-user-questions over the question pending table), and Session navigation identifies approval, plan-review, and ordinary question waits before the user opens them. The permission select reads once per mount; live refresh from another client's switch is deferred. Coverage includes the policy decision matrix and public-address preflight, proxy registry and permission RPC suites, session-object and fixture suites, the keyless web smoke for fixture-mode approval and preset switching, and real-composition plan-review and question snapshots that pin pending sidebar status through resolution.

 Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.
 
 Use subagent in the background by default. Start independent delegations together in one assistant message and continue useful work while they run. Set `run_in_background: false` only when your next action depends on that subagent's result. When a background run settles, the runtime sends you a notice containing its outcome and any final assistant message.

 Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.

It owns model-facing concerns only: tool names, JSON schemas, snake_case argument names, prompt sections, the result-count bound, result formatting, HTML→markdown presentation, and the UI presentation projection — `presentCall`, `presentResult` (a `card: 'web'` result card discriminated by `kind: 'search' | 'fetch'`), and the `output.presentationMeta` that carries the structured search sources or the fetch summary the lossy render text cannot (see the [web-result-card Agent Note](../../../.agents/notes/implemented/feature/2026-07-30-web-result-card.md)). All web access goes through `ctx.web`; this package never imports a concrete provider. Neither tool exposes a model-facing timeout — each tool's cooperative tool-call budget is declared here via config (`fetchTimeoutMs`/`searchTimeoutMs`, attached as `ToolDefinition.timeoutMs`) and enforced by [`@deepseek-ai/dsh-tool-call-timeout-policy`](../../guard/timeout-policy/README.md) (a `tools/execute` wrapper). Single operations forward `exec.signal`; a multi-query search fuses it with batch cancellation so a failed query aborts its siblings.

 Each tool is registered independently; a product that wants only one disables the other via config (`{ search: false }` / `{ fetch: false }`). Search guidance mentions `web_fetch` only when fetch is also config-enabled; a search-only composition instead tells the model to use returned snippets and cite their URLs.

 ## Known Limitations and Deferred Work
 
 - **There is no batch-wide native-search counter** — `searchMaxQueries` bounds `ctx.web.search` calls, but a provider may perform several native searches inside each call. For example, a model-backed provider configured with `maxUses` can permit up to `searchMaxQueries × maxUses` native searches; `searchMaxResults` limits only the combined sources returned to the caller. Deployments control cost through these independent consumer and provider settings because the generic seam does not know provider-internal search units.
-- **HTML→markdown conversion degrades on inputs GFM cannot safely represent** — [turndown](https://github.com/mixmark-io/turndown) (with GFM tables/strikethrough) converts at most `fetchMaxOutputChars` source characters through a real DOM. A conservative 512-level lexical guard passes deeply or ambiguously nested bodies through as raw HTML, conversion exceptions do the same, and table `colspan` is ignored because GFM has no spanning-cell representation; these bounds avoid blocking the event loop or expanding output from an untrusted numeric attribute ([archived dependency decision](../../../.agents/notes/archived/simplification/2026-07-26-turndown-for-tool-web-html-markdown.md)).

 - **The model-facing API is minimal by design, with promotions deferred** — `max_results` stays a config bound (not a model argument), and `web_fetch` takes only `url` (no `format`/`prompt`/LLM-summarization mode); both are named later steps in [the seam Agent Note](../../../.agents/notes/implemented/architecture/2026-06-24-web-capability-seam.md).
-- **No web-specific permission policy** — both tools execute without requesting `ctx.approval`; a deployment that needs confirmation must add a `tools/pre-execute` policy, and the package does not define persistent URL/domain grants.
+- **Permission remains composition-owned** — this tool package does not request `ctx.approval` itself. Shipped compositions mount [`dsh-web-fetch-approval-policy`](../web-fetch-approval-policy/README.md) for `web_fetch`; custom compositions may replace it, and no package defines persistent URL/domain grants.

-A `tools/pre-execute` policy for one-shot `web_fetch` permission decisions. It combines the calling session's sandbox mode with its approval policy and uses [`dsh-web-fetch-http`](../web-fetch-http/README.md) to reject non-public destinations before asking the user.
+A `tools/pre-execute` policy for one-shot `web_fetch` permission decisions. It combines the calling session's sandbox mode with its approval policy and uses [`dsh-web-fetch-http`](../web-fetch-http/README.md) for network-free validation before asking the user.
 
 ## Decisions
 
 | Sandbox mode | Approval policy | `web_fetch` decision |
 |---|---|---|
 | `danger-full-access` | any | Delegate without asking. |
-| `read-only` or `workspace-write` | `ask` | Resolve and require a public destination, then request one-shot approval. |
+| `read-only` or `workspace-write` | `ask` | Validate the URL without network activity, then request one-shot approval. |
 | `read-only` or `workspace-write` | `never` | Deny without DNS or a prompt. |
 
-An agentless restricted call is denied because it has no session for policy lookup or approval audit. Malformed arguments delegate to the tool's own schema validation. This plugin never grants a call itself: unrestricted calls delegate to later policies, and restricted calls preserve any downstream `ask` or `deny` result.
+An agentless restricted call is denied because it has no session for policy lookup or approval audit; agentless `danger-full-access` calls delegate. Malformed arguments and unknown tools delegate to the registry's own validation. This plugin never grants a call itself: it evaluates downstream policies first, unrestricted calls preserve their result, and restricted calls ask only after downstream policies allow.
 
 The approval request carries the exact tool `callId` and a reason containing the complete normalized URL, sandbox mode, and single-call scope. Only the existing `allowed-once` outcome permits execution; rejection, cancellation, or an unavailable answerer fails closed. Session/domain persistence and permanent grants are outside this package.
 
 ## SSRF separation
 
-Permission preflight parses the URL and resolves its complete address set before displaying a prompt. A non-public destination is always rejected and cannot be authorized through `allowed-once`.
+Before displaying a prompt, permission validation checks URL syntax, the fixed length limit, embedded credentials, and any literal IP address. It performs no DNS lookup, so rejecting or cancelling a prompt cannot disclose model-controlled hostname data through the resolver.
 
-Preflight is not a network authorization token. The HTTP provider resolves the hostname again immediately before each connection, rejects any non-public answer, pins the validated addresses, and repeats the check for every followed same-origin redirect. Cross-origin redirects require a new `web_fetch` call and a new permission decision.
+After `allowed-once`, the HTTP provider resolves the hostname immediately before each connection, rejects any non-public answer, pins the validated addresses, and repeats the check for every followed same-origin redirect. A user cannot authorize a private destination, and cross-origin redirects require a new `web_fetch` call and permission decision.

+一个为 `web_fetch` 作单次权限决策的 `tools/pre-execute` 策略。它组合调用会话的 sandbox mode 与审批策略，并使用 [`dsh-web-fetch-http`](../web-fetch-http/README.zh.md) 在询问用户前执行不产生网络活动的校验。
 
 ## 决策
 
 | Sandbox mode | 审批策略 | `web_fetch` 决策 |
 |---|---|---|
 | `danger-full-access` | 任意 | 不询问并委托后续策略。 |
-| `read-only` 或 `workspace-write` | `ask` | 解析并要求目的地址公开，然后请求单次审批。 |
+| `read-only` 或 `workspace-write` | `ask` | 不产生网络活动地校验 URL，然后请求单次审批。 |
 | `read-only` 或 `workspace-write` | `never` | 不进行 DNS 解析或提示，直接拒绝。 |
 
-受限模式下的无 agent 调用会被拒绝，因为它没有可用于策略查询和审批审计的 session。格式错误的参数交给工具自身的 schema 校验。此插件从不自行授予调用：不受限的调用会委托后续策略，受限调用也会保留下游的 `ask` 或 `deny` 结果。
+受限模式下的无 agent 调用会被拒绝，因为它没有可用于策略查询和审批审计的 session；无 agent 的 `danger-full-access` 调用会继续委托。格式错误的参数和未知工具交给注册表自身校验。此插件从不自行授予调用：它先计算下游策略，不受限调用保留下游结果，受限调用也只会在下游允许后询问。
 
 审批请求携带精确的工具 `callId`，其 reason 包含完整的标准化 URL、sandbox mode 与单次调用范围。只有现有的 `allowed-once` 结果允许执行；拒绝、取消或无可用回答方都会 fail closed。按 session／域名持久化和永久授权不属于此包。
 
 ## SSRF 分离
 
-权限预检会在显示提示前解析 URL 及其完整地址集合。非公开目的地址始终被拒绝，不能通过 `allowed-once` 授权。
+权限校验会在显示提示前检查 URL 语法、固定长度上限、内嵌凭据和 IP 字面量。它不执行 DNS 查询，因此拒绝或取消提示不会通过解析器泄露由模型控制的 hostname 数据。
 
-预检不是网络授权令牌。HTTP 提供方会在每次实际连接前重新解析 hostname，拒绝任何非公开解析结果，固定已验证地址，并对每个被跟随的同源重定向重复校验。跨源重定向需要新的 `web_fetch` 调用和新的权限决策。
+`allowed-once` 之后，HTTP 提供方才会在每次实际连接前解析 hostname、拒绝任何非公开解析结果、固定已验证地址，并对每个被跟随的同源重定向重复校验。用户不能授权私有目的地址；跨源重定向需要新的 `web_fetch` 调用和权限决策。

-- Accepts only `http:` and `https:` URLs; rejects credentials in URLs (`WEB_BLOCKED_URL`) and over-long/malformed URLs (`WEB_INVALID_URL`).
-- Resolves each hostname once, rejects the complete answer set if any IPv4 or IPv6 destination is not public unicast (`WEB_BLOCKED_URL`), and pins the connection to that validated set. This blocks loopback, private, link-local, carrier-grade NAT, multicast, reserved, transition, translation, and private IPv4-mapped IPv6 destinations without a second DNS lookup.
-- Enforces a max URL length, response byte cap (`WEB_FETCH_TOO_LARGE`), decoded body character cap, timeout (`WEB_FETCH_TIMEOUT`), and redirect hop cap.
+- Accepts only `http:` and `https:` URLs; rejects credentials in URLs (`WEB_BLOCKED_URL`) and URLs over the fixed 2,048-character security limit or otherwise malformed (`WEB_INVALID_URL`).
+- Resolves each hostname once, rejects the complete answer set if any IPv4 or IPv6 destination is not public unicast (`WEB_BLOCKED_URL`), and pins the connection to that validated set. For IPv6 answers it discovers the active DNS64 prefix through `ipv4only.arpa` and rejects NAT64 translations to non-public IPv4. This blocks loopback, private, link-local, carrier-grade NAT, multicast, reserved, transition, translation, and private IPv4-mapped IPv6 destinations without resolving the target hostname twice.
+- Enforces the URL limit, response byte cap (`WEB_FETCH_TOO_LARGE`), decoded body character cap, timeout (`WEB_FETCH_TIMEOUT`), and redirect hop cap.
 - Propagates the caller's abort signal (`WEB_ABORTED`) into the network request and the streaming read.
 - Follows only **same-origin** redirects; each followed hop repeats public-address resolution and pinning, while a cross-origin redirect fails with `WEB_REDIRECT_BLOCKED` and requires a fresh tool call (the model of Claude Code's WebFetch).
 - Sends an explicit product `User-Agent`, never a browser disguise.
 - Rejects unsupported (e.g. binary) content types with `WEB_UNSUPPORTED_CONTENT_TYPE`.
 
-`preflightPublicFetchUrl()` exposes the URL syntax and public-address check to permission consumers. Its result is advisory, not authorization: the provider always resolves again and pins the actual connection, so DNS changes between approval and execution cannot bypass the destination policy.
+`validateFetchApprovalUrl()` exposes network-free URL syntax, length, credentials, and literal-IP checks to permission consumers. Hostname resolution remains exclusively in the provider after consent, where the result is enforced and pinned rather than reused as an authorization token.

-| `maxUrlLength` | `2048` | Maximum accepted request URL length. |
 | `maxResponseBytes` | `5_000_000` | Maximum response body size in bytes. |
 | `maxBodyChars` | `100_000` | Maximum decoded body length in characters. |
 | `timeoutMs` | `30_000` | Fetch timeout within Node's timer range — a resource backstop for direct `ctx.web.fetch()` callers, not the model-facing tool-call budget (that is `dsh-tool-call-timeout-policy`). |
 | `maxRedirects` | `5` | Maximum same-origin redirect hops (`0` follows none). |
 | `userAgent` | `deepseek-harness/…` | `User-Agent` header. |
 
-The numeric limits are validated at plugin construction: every cap except `maxRedirects` must be a positive finite number, and `maxRedirects` must be a non-negative integer. An invalid value throws rather than silently constructing a provider with nonsensical limits.

From ce653101834c7a5af30697696e8e611ee2b173ad Mon Sep 17 00:00:00 2001
From: _Kerman <kermanx@qq.com>
Date: Tue, 25 Aug 2026 11:48:12 +0800
Subject: [PATCH 074/155] fix(ci): keep the base projection cache out of
 listing-less profiles
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The base-mounted projection cache's write-behind forces session-log flushes
at cache-chosen times, splitting packed chunk rows and changing the durable
JSONL batching the keyless headless and sdk replay fixtures pin. Neither
profile exposes a session-listing surface — the one-shot runner and the SDK
protocol — so both bundles disable the base row, restoring the pre-base
behavior the fixtures were recorded against (the same pattern acp-app uses).

+The dsh one-shot bundle. [`cordis.patch.yml`](cordis.patch.yml) rides directly over [`dsh-base`](../base/README.md): it inherits the base's disabled module-HMR policy, supplies the coding persona and tool mode, mounts Code Mode's worker as a core execution capability, and inserts this package's `headless-runner` plugin (config `{task}`, resolved from the injected `headlessStartup` provider). It mounts no Host, HTTP server, Web runtime, or browser plugin. It also keeps the base projection cache disabled: the one-shot runner exposes no session-listing surface, and the cache's write-behind would force session-log flushes at cache-chosen times, changing the durable JSONL batching this profile's keyless replay fixtures pin.
 
 After the Loader settles, the runner reads the shared [`ctx.agentDefaultModel`](../../core/agent-default-model/README.md), creates one fresh persisted Agent through `ctx.agents`, submits the task as an ordinary user message, and waits for quiescence. It flushes the Session before folding the owned durable event interval, writes the last non-empty assistant text to stdout, and requests exit through the launcher-provided `ctx.appExit` host hook ([`dsh-cmdline`](../../boot/cmdline/README.md)) (final `turn/end` completed → 0, otherwise 1). A terminal `error` reason also writes its code and message to stderr; successful runs keep stderr empty. The process opens no listening port. The task text is this app's command line: the ordinary `headless-startup` provider ([`src/startup.ts`](src/startup.ts)) injects `ctx.cmdlineArgs` ([`dsh-cmdline`](../../boot/cmdline/README.md)), reads the positional argument of `dsh --profile headless "task"`, prints the app's `--help`, and provides `headlessStartup`; the runner injects that service and reads its task from lazy config. A missing or whitespace-only task is rejected before the runner activates.

 Loader 结算后，runner 读取共享的 [`ctx.agentDefaultModel`](../../core/agent-default-model/README.zh.md)，通过 `ctx.agents` 创建一个全新的持久化 Agent（智能体），将任务作为普通用户消息提交，并等待完全停稳。它对 Session 执行 flush 后再汇总自身持有的持久化事件区间，将最后一条非空 assistant 文本写入 stdout，再经启动器提供的 `ctx.appExit` 宿主钩子（[`dsh-cmdline`](../../boot/cmdline/README.zh.md)）请求退出（最终 `turn/end` 完成 → 0，否则为 1）。最终结束原因为 `error` 时，还会将 code 与 message 写入 stderr；成功运行时 stderr 保持为空。进程不会打开监听端口。任务文本就是这个应用的命令行：普通 `headless-startup` 提供方（[`src/startup.ts`](src/startup.ts)）注入 `ctx.cmdlineArgs`（[`dsh-cmdline`](../../boot/cmdline/README.zh.md)），读取 `dsh --profile headless "task"` 的位置参数、打印应用自己的 `--help`，并提供 `headlessStartup`；runner 注入该服务，再从惰性配置中读取任务。缺失或只有空白的任务会在 runner 激活前被拒绝。

 The SDK stdio application as a `dsh` profile bundle over [`dsh-base`](../base/README.md). It inherits the base's disabled module-HMR policy; its patch sets the coding-agent persona, mounts an app-owned zero-option command provider, and starts [`dsh-sdk-jsonrpc-server`](../../sdk/server/README.md) only after that provider accepts the invocation. `dsh --profile sdk --help` therefore writes help and exits without claiming stdin or stdout. The standalone [`sdk-minimal`](../sdk-minimal/README.md) bundle reuses the same startup provider and supplies its own profile name.
 
-The startup provider binds stdin EOF to the launcher's bounded successful shutdown. SDK protocol `shutdown`, SIGINT, and SIGTERM retain their owning server or launcher paths; disposal drains the root profile tree and persistence. Stdout is reserved for newline-delimited JSON-RPC frames. The bundle disables model-generated session titles because the SDK exposes no title surface; deterministic fallback titles remain durable without an auxiliary model request. A deployment selects a different complete composition through profile bundles and patch files, not another app bin.

Subject: [PATCH 076/155] test(credentials-local): seed fixtures atomically to
 close a boot-read race

The concurrent-migrator test wrote the winner document with a plain
writeFile, whose truncate-then-write window lets the boot's unlocked
initial read observe an empty file and boot an empty store under load.
Seed fixtures through writeFileAtomic instead, matching how the provider
itself persists, so a reader sees either the old or the new complete
document.

 - Abort signals propagate through network fetches and expensive decoding.

 - Requests carry an explicit product user agent rather than silently impersonating a browser.
 
 The provider rejects an entire DNS answer set when any address is not public instead of silently filtering the unsafe members. This fail-closed rule prevents connection-family selection or fallback from reaching an address that did not satisfy the public-network policy.
 
-`dsh-web-fetch-approval-policy` owns user-consent decisions without moving them into the provider or tool schema. It evaluates downstream policies first and delegates `danger-full-access`; in `read-only` and `workspace-write` it denies approval policy `never`, otherwise performs network-free URL syntax, length, credentials, and literal-IP checks before returning `ask`. The existing approval service correlates the request to the exact call id, and only `allowed-once` runs that call. The provider then independently resolves, validates, and pins the actual connection, so rejection causes no DNS query and consent cannot bypass SSRF enforcement. Plan mode stays an independent collaboration state and uses whichever sandbox and approval policies the product composes with it.

-The shipped web composition also mounts `dsh-web-fetch-approval-policy` on `tools/pre-execute`. It evaluates downstream policies before a `web_fetch` decision. `danger-full-access` delegates without asking; `read-only` and `workspace-write` apply network-free URL syntax, length, credentials, and literal-IP checks before one-shot approval; approval policy `never` denies without resolving or prompting. After `allowed-once`, the provider resolves and pins the actual connection, rejects every non-public answer including private IPv4 reached through the active DNS64 prefix, and repeats enforcement at each same-origin redirect. The policy therefore leaks no hostname through DNS before consent, and a grant cannot authorize a private destination or DNS-rebinding answer. `plan` stays independent collaboration state, and products restrict plan work by composing it with a restricted sandbox preset rather than adding a second network-mode vocabulary.

 `createApiProxy` owns the approval pending registry. Its `approval/request` waterfall answerer reads the approval id from the session's just-appended `approval/asked` audit event (an ask with no audit event is a foreign channel and delegates), mints one stable rpcId per question, broadcasts the answerable `approval/requested` frame to every open mux stream, and replays still-pending frames verbatim on each mux open — the refresh-recovery baseline the contract already promised. `respond` routes by the echoed rpcId, validates `ApprovalResponsePayload` with the existing zod schema, cross-checks the payload's audit correlation against the routed entry, resolves the answerer, and broadcasts `approval/resolved`; the ask's abort signal withdraws the question as `cancelled`.
 
 The permission select rides two new unary RPCs, `session.permissions` and `session.setPermission`, projecting `ctx.permissionPresets` into a protocol-owned `PermissionOption` DTO (the ACP bridge precedent: each protocol owns its presentation shape). A permission-less composition serves an empty select and clients hide the control. Idle switches are held last-write-wins in a proxy-side pending map and flushed on `agent/pre-step`, because knob events must stay turn-enclosed for durable replay; the shared `hasOpenTurn` fold moved to `dsh-session` and replaced the private copies in `dsh-user-approval`, the ACP bridge, and the proxy.

 ## Consequences
 
-Web sessions start confined (`workspace-write` + `ask` by default), and `web_fetch` pauses for an answerable one-shot request before hostname resolution. A sandbox-denial escalation reaches the browser through the same channel. The deployment can widen or narrow the default through `BootHostOptions.sandbox` without touching the assembly. Question answering uses the same registry pattern (ui-user-questions over the question pending table), and Session navigation identifies approval, plan-review, and ordinary question waits before the user opens them. The permission select reads once per mount; live refresh from another client's switch is deferred. Coverage includes the policy decision matrix with zero resolver calls on rejection, public-address and DNS64 enforcement, proxy registry and permission RPC suites, session-object and fixture suites, the keyless web smoke for fixture-mode approval and preset switching, and an assembled ACP snapshot that pins `ask` → `allowed-once` → fixed-address HTTP → sanitized model-visible content.

-**`dsh-web-fetch-http`** stays unmounted and `dsh-tool-web` keeps `fetch: false`. The provider restricts connections to validated public IP destinations, but `dsh-tool-web` has no web-specific permission policy and executes without asking `ctx.approval` ([README](../../../../packages/web/tool-web/README.md)). The shipped permission presets therefore do not silently broaden from sandboxed file access to model-selected public network requests.

-Withholding it narrows the surface without removing the reach: `bash` is mounted, so `curl` gets the same page, as a live run confirmed. What the absence buys is the removal of an argument-shaped request primitive that needs no shell — and with it the accidental path where a summarization request quietly reaches loopback. A deployment that must contain outbound traffic needs a network-level control.
-
 **The LSP trio** stays out for an operational reason rather than a security one: `command` resolves from `PATH` at plugin load, so a missing language server fails the whole boot rather than one tool. It becomes mountable once absence degrades to a skipped registration.

 ## Decision
 
-`apps/cli/config/base.cordis.yml` explicitly mounts `dsh-web` with `searchProvider: deepseek-official`, `dsh-web-search-deepseek`, and `dsh-tool-web` with `fetch: false` and `searchTimeoutMs: 60000`. It does not mount `dsh-web-fetch-http` or select a fetch provider. The shared base makes only `web_search` a default for TUI, browser, and headless sessions. The explicit search provider id keeps selection independent of registration order and leaves personal or `--config` overlays able to replace or disable the rows. The one-minute shipped budget covers an auxiliary DeepSeek Messages request plus server-side retrieval while leaving `dsh-tool-web`'s provider-neutral 30-second default unchanged for custom compositions.
+`apps/cli/config/base.cordis.yml` explicitly mounts `dsh-web` with `searchProvider: deepseek-official` and `fetchProvider: http`, `dsh-web-search-deepseek`, `dsh-web-fetch-http`, and `dsh-tool-web` with `fetch: false` and `searchTimeoutMs: 60000`. The shared base therefore keeps only `web_search` visible unless a product preset enables fetch; the shipped Web `cordis`, `code`, and `standard` presets do so. Explicit provider ids keep selection independent of registration order and leave personal or `--config` overlays able to replace or disable the rows. The one-minute shipped budget covers an auxiliary DeepSeek Messages request plus server-side retrieval while leaving `dsh-tool-web`'s provider-neutral 30-second default unchanged for custom compositions. The [Web capability seam decision](../architecture/2026-06-24-web-capability-seam.md) owns the public-fetch security policy and Web preset default.
 
 DeepSeek search uses the same `DEEPSEEK_API_KEY` credential reference as the official conversation adapter. The provider resolves that reference inside every search through the optional `ctx.credentials` service; only a composition without the seam falls back to the launching process environment, and a non-empty literal `apiKey` remains the programmatic last resort. A stored or rotated Web Models key therefore reaches the next search without restarting or retaining the value on the provider. Because `WebSearchProvider.available()` is synchronous, it treats an installed resolver as locally usable and missing dynamic credentials fail the operation with the provider-specific `WEB_PROVIDER_CREDENTIAL_MISSING` code while the stable tool schema stays registered.
 
 Search keeps its endpoint distinct from chat completions: `DEEPSEEK_SEARCH_BASE_URL` overrides the Anthropic-compatible base, while `DEEPSEEK_BASE_URL` continues to configure conversation requests. Each `web_search` performs an auxiliary DeepSeek Messages call with the native search server tool. Immediately before dispatch, the provider appends a log-only `web/deepseek-search-llm-request` event to the initiating Agent session with the resolved endpoint, API version, and exact secret-free JSON body. Credential preflight remains provider-local and races caller cancellation; neither concern expands the generic Web or credentials seams.
 
-The default mount does not create a Web-specific permission policy. `web_search` executes outside the shell/filesystem sandbox and approval presets, following `dsh-tool-web`'s existing contract. It does not mount `web_fetch` or a local fetch provider, so the default does not grant model-selected arbitrary URL retrieval. The shipped `workspace-write` default governs file mutations only; a restricted-network product stance requires a `tools/pre-execute` policy or capability-specific network confinement rather than implying that filesystem access mode governs Web calls.
+The default mount does not create a Web-specific permission policy. `web_search` and enabled `web_fetch` calls execute outside the shell/filesystem sandbox and approval presets, following `dsh-tool-web`'s existing contract.

 **Raise `dsh-tool-web`'s provider-neutral timeout.** Rejected because custom providers and deployments own different latency expectations; the shipped DeepSeek composition owns this deployment budget.
 
-**Enable search and fetch together.** Rejected because default `web_fetch` would allow model-selected anonymous outbound HTTP(S) retrieval to arbitrary URLs. Search covers discovery; deployments that accept broader retrieval can opt into `dsh-web-fetch-http` and set `dsh-tool-web`'s `fetch` option to `true` in their overlay.
+**Enable fetch on every shared-base surface.** Rejected because the shared base serves products with different network postures. It mounts the public-only provider but keeps the tool opt-in; the shipped Web presets deliberately enable it, while another product can leave it hidden or add stricter network policy.
 
 ## Consequences
 
-Native model requests on every shipped surface carry only the `web_search` schema and search-only prompt guidance; Web/headless Code Mode exposes the same search capability beneath `run_code`. The prompt tells the model to use returned snippets and never advertises the disabled `web_fetch` tool. Search adds a complete auxiliary model call and may use the native server tool multiple times; its exact secret-free request remains reconstructable from the initiating session log. The default offers search-result snippets and source metadata but no arbitrary page retrieval; deployments that need full-page fetch must opt in. The Web snapshot lane boots the shipped tree, drives a replayed `web_search` call through the real DeepSeek provider against a local Messages fixture, asserts the durable auxiliary request and structured result, and pins the settled browser presentation. The TUI/Web composition smokes pin the shared `web_search` roster and absence of `web_fetch`; the built composition dump pins the one-minute shipped search budget; provider tests pin missing, stored, and rotated credential behavior plus literal and ambient compatibility.

 DeepSeek 搜索使用与官方会话适配器相同的 `DEEPSEEK_API_KEY` 凭据引用。提供方在每次搜索内部通过可选的 `ctx.credentials` 服务解析该引用；只有未挂载该 seam 的组合才会回退到启动进程的环境变量，非空的 `apiKey` 字面值仍作为程序化配置的最后兜底。因此，由 Web 的 Models 页存储或轮换的密钥无需重启即可用于下一次搜索，提供方也无需保留该值。由于 `WebSearchProvider.available()` 是同步方法，它会将已安装解析器视为本地可用；若动态凭据缺失，操作会以提供方专属错误码 `WEB_PROVIDER_CREDENTIAL_MISSING` 失败，而稳定的工具 schema 仍保持注册。
 
 搜索端点与 chat completions 保持独立：`DEEPSEEK_SEARCH_BASE_URL` 覆盖 Anthropic 兼容基址，`DEEPSEEK_BASE_URL` 则继续配置会话请求。每次 `web_search` 都会发起一次辅助 DeepSeek Messages 调用，并携带原生搜索服务器工具。发出请求前一刻，提供方会向发起请求的 agent（智能体）会话追加仅用于日志的 LLM（大语言模型）请求事件 `web/deepseek-search-llm-request`，其中包含已解析端点、API 版本，以及不含密钥的精确 JSON 请求体。凭据预检仍留在提供方内部，并与调用方取消存在竞态；这两项关注点都不会扩展通用 Web seam 或凭据 seam。
 
-默认挂载不会创建 Web 专用权限策略。`web_search` 在 bash／文件系统沙箱及审批预设之外执行，并遵循 `dsh-tool-web` 的现有约定。组合不挂载 `web_fetch` 或本地抓取提供方，因此默认配置不会允许模型自行选择任意 URL 进行抓取。已交付的 `workspace-write` 默认值只管辖文件修改；若产品采取受限网络策略，就需要添加 `tools/pre-execute` 策略或按能力限制网络访问，而不能暗示文件系统访问模式会管辖 Web 调用。

Provider credentials resolve from the inherited environment, `$DSH_HOME/.credentials.yaml`, the invoking directory's `.env`, then `$DSH_HOME/.env`; the managed document is never materialized into `process.env`, while both `.env` files are ordinary launch environment layers. Search uses `DEEPSEEK_API_KEY` and accepts `DEEPSEEK_SEARCH_BASE_URL`. The Web app's `cordis`, `code`, and `standard` agent presets expose `web_fetch`; restricted sandbox modes ask once per public URL call, `danger-full-access` delegates without asking, and approval policy `never` denies restricted calls without prompting.

 Session telemetry stays local by default. `DSH_TELEMETRY_MODE=FULL` streams every projected session event as OTLP/HTTP logs, while `DSH_TELEMETRY_MODE=FEEDBACK_ONLY` uploads a session-log suffix only when feedback is recorded. `DSH_TELEMETRY_OTLP_URL` selects another collector, and any non-empty `DSH_TELEMETRY_DISABLED` remains an authoritative hard opt-out. The shipped base has no telemetry redaction rule, so explicitly enabled exports can contain message text, tool arguments and results, and workspace paths; the [default-off Agent Note](../../../.agents/notes/implemented/feature/2026-08-10-telemetry-default-off.md) owns that deployment decision.

-[`dsh-web-fetch-approval-policy`](../../packages/web/web-fetch-approval-policy) listens on `tools/pre-execute` without changing the web service or tool schemas. It evaluates downstream policies first. `danger-full-access` delegates without asking; `read-only` and `workspace-write` with approval policy `ask` validate URL syntax, length, credentials, and literal IPs without network activity, then return `ask` with the exact call id and full normalized URL. Approval policy `never` and agentless restricted calls deny without DNS or a prompt. Only `allowed-once` grants the pending call; there is no persistent domain or session authorization.
+The shipped Cordis, Code, and Standard presets expose `web_fetch` in every sandbox and approval mode without per-call confirmation. File sandbox presets do not govern Web network access. A deployment that needs confirmation must add a `tools/pre-execute` policy or disable fetch.
 
-Permission validation and provider enforcement are separate. DNS runs only after consent: the HTTP provider resolves for the actual request, rejects non-public answers including private IPv4 reached through the active DNS64 prefix, pins that validated address set, and repeats enforcement for each same-origin redirect. A cross-origin redirect requires a new tool call and permission decision. `plan` remains collaboration state rather than a network mode, so products combine plan work with the desired sandbox and approval policies.

 - **There is no batch-wide native-search counter** — `searchMaxQueries` bounds `ctx.web.search` calls, but a provider may perform several native searches inside each call. For example, a model-backed provider configured with `maxUses` can permit up to `searchMaxQueries × maxUses` native searches; `searchMaxResults` limits only the combined sources returned to the caller. Deployments control cost through these independent consumer and provider settings because the generic seam does not know provider-internal search units.
 - **HTML→markdown conversion omits inputs it cannot safely represent** — [turndown](https://github.com/mixmark-io/turndown) (with GFM tables/strikethrough) converts at most `fetchMaxOutputChars` source characters through a real DOM. A conservative 512-level lexical guard and conversion exceptions produce a fixed omission marker rather than raw HTML, and table `colspan` is ignored because GFM has no spanning-cell representation; these bounds avoid blocking the event loop or expanding output from an untrusted numeric attribute ([archived dependency decision](../../../.agents/notes/archived/simplification/2026-07-26-turndown-for-tool-web-html-markdown.md)).
 - **The model-facing API is minimal by design, with promotions deferred** — `max_results` stays a config bound (not a model argument), and `web_fetch` takes only `url` (no `format`/`prompt`/LLM-summarization mode); both are named later steps in [the seam Agent Note](../../../.agents/notes/implemented/architecture/2026-06-24-web-capability-seam.md).
-- **Permission remains composition-owned** — this tool package does not request `ctx.approval` itself. Shipped compositions mount [`dsh-web-fetch-approval-policy`](../web-fetch-approval-policy/README.md) for `web_fetch`; custom compositions may replace it, and no package defines persistent URL/domain grants.
+- **Public fetches do not request approval** — the shipped `cordis`, `code`, and `standard` presets expose `web_fetch` in every sandbox and approval mode. The HTTP provider blocks non-public destinations, but a model can send data to a public URL. Deployments that require per-call confirmation must add a `tools/pre-execute` policy or disable fetch.

 - **没有覆盖整个批次的原生搜索计数器**：`searchMaxQueries` 限制 `ctx.web.search` 调用数，但提供方可以在每次调用内执行多次原生搜索。例如，配置了 `maxUses` 的模型型提供方最多可以执行 `searchMaxQueries × maxUses` 次原生搜索；`searchMaxResults` 只限制返回给调用方的组合来源。部署通过这些独立的消费方与提供方设置控制成本，因为通用 seam 不知道提供方内部的搜索计量单位。
 - **HTML→markdown 转换会省略无法安全表示的输入**：[turndown](https://github.com/mixmark-io/turndown)（带 GFM 表格／删除线）通过真实 DOM 转换至多 `fetchMaxOutputChars` 个源字符。保守的 512 层词法守卫和转换异常会产生固定省略标记，而不会返回原始 HTML；表格的 `colspan` 会被忽略，因为 GFM 无法表示跨列单元格。这些限制可避免阻塞事件循环，也避免不受信任的数值属性使输出膨胀（[已归档的依赖决策](../../../.agents/notes/archived/simplification/2026-07-26-turndown-for-tool-web-html-markdown.md)）。
 - **面向模型的接口有意保持精简，后续扩展暂缓**：`max_results` 保持为配置上限（不是模型参数），`web_fetch` 只接受 `url`（没有 `format`／`prompt`／LLM（大语言模型）摘要模式）；两项都列为 [seam Agent Note](../../../.agents/notes/implemented/architecture/2026-06-24-web-capability-seam.zh.md) 中的后续步骤。

-# @deepseek-ai/dsh-web-fetch-approval-policy
-
-English | [中文](README.zh.md)
-
-A `tools/pre-execute` policy for one-shot `web_fetch` permission decisions. It combines the calling session's sandbox mode with its approval policy and uses [`dsh-web-fetch-http`](../web-fetch-http/README.md) for network-free validation before asking the user.
-
-## Decisions
-
-| Sandbox mode | Approval policy | `web_fetch` decision |
-|---|---|---|
-| `danger-full-access` | any | Delegate without asking. |
-| `read-only` or `workspace-write` | `ask` | Validate the URL without network activity, then request one-shot approval. |
-| `read-only` or `workspace-write` | `never` | Deny without DNS or a prompt. |
-
-An agentless restricted call is denied because it has no session for policy lookup or approval audit; agentless `danger-full-access` calls delegate. Malformed arguments and unknown tools delegate to the registry's own validation. This plugin never grants a call itself: it evaluates downstream policies first, unrestricted calls preserve their result, and restricted calls ask only after downstream policies allow.
-
-The approval request carries the exact tool `callId` and a reason containing the complete normalized URL, sandbox mode, and single-call scope. Only the existing `allowed-once` outcome permits execution; rejection, cancellation, or an unavailable answerer fails closed. Session/domain persistence and permanent grants are outside this package.
-
-## SSRF separation
-
-Before displaying a prompt, permission validation checks URL syntax, the fixed length limit, embedded credentials, and any literal IP address. It performs no DNS lookup, so rejecting or cancelling a prompt cannot disclose model-controlled hostname data through the resolver.
-
-After `allowed-once`, the HTTP provider resolves the hostname immediately before each connection, rejects any non-public answer, pins the validated addresses, and repeats the check for every followed same-origin redirect. A user cannot authorize a private destination, and cross-origin redirects require a new `web_fetch` call and permission decision.
-
-## Model Experience
-
-Indirectly, through `dsh-tools` and `dsh-user-approval`, which pause restricted calls for one-shot approval and return denial through the existing tool-error path.
-
-#### KV Cache effect
-
-None. The policy changes execution, not model-visible schemas or prompt text.
-
-## Known Limitations and Deferred Work
-
-- There is no session- or domain-scoped persistent grant.
-- `plan` is collaboration state, not a sandbox mode. Products that want plan work to use restricted web access compose it with `read-only` or `workspace-write` and approval policy `ask`.

-
-一个为 `web_fetch` 作单次权限决策的 `tools/pre-execute` 策略。它组合调用会话的 sandbox mode 与审批策略，并使用 [`dsh-web-fetch-http`](../web-fetch-http/README.zh.md) 在询问用户前执行不产生网络活动的校验。
-
-## 决策
-
-| Sandbox mode | 审批策略 | `web_fetch` 决策 |
-|---|---|---|
-| `danger-full-access` | 任意 | 不询问并委托后续策略。 |
-| `read-only` 或 `workspace-write` | `ask` | 不产生网络活动地校验 URL，然后请求单次审批。 |
-| `read-only` 或 `workspace-write` | `never` | 不进行 DNS 解析或提示，直接拒绝。 |
-
-受限模式下的无 agent 调用会被拒绝，因为它没有可用于策略查询和审批审计的 session；无 agent 的 `danger-full-access` 调用会继续委托。格式错误的参数和未知工具交给注册表自身校验。此插件从不自行授予调用：它先计算下游策略，不受限调用保留下游结果，受限调用也只会在下游允许后询问。
-
-审批请求携带精确的工具 `callId`，其 reason 包含完整的标准化 URL、sandbox mode 与单次调用范围。只有现有的 `allowed-once` 结果允许执行；拒绝、取消或无可用回答方都会 fail closed。按 session／域名持久化和永久授权不属于此包。
-
-## SSRF 分离
-
-权限校验会在显示提示前检查 URL 语法、固定长度上限、内嵌凭据和 IP 字面量。它不执行 DNS 查询，因此拒绝或取消提示不会通过解析器泄露由模型控制的 hostname 数据。
-
-`allowed-once` 之后，HTTP 提供方才会在每次实际连接前解析 hostname、拒绝任何非公开解析结果、固定已验证地址，并对每个被跟随的同源重定向重复校验。用户不能授权私有目的地址；跨源重定向需要新的 `web_fetch` 调用和权限决策。
-
-## 模型体验
-
-通过 `dsh-tools` 与 `dsh-user-approval` 间接影响；它们让受限调用等待单次审批，并通过既有工具错误路径返回拒绝结果。
-
-#### KV Cache 影响
-
-无。该策略改变执行，不改变面向模型的 schema 或提示词文本。
-
-## 已知限制与暂缓事项
-
-- 不存在按 session 或域名限定的持久授权。
-- `plan` 是协作状态，不是 sandbox mode。希望 plan 工作采用受限 Web 访问的产品，应将其与 `read-only` 或 `workspace-write` 以及审批策略 `ask` 组合。

 - Sends an explicit product `User-Agent`, never a browser disguise.
 - Rejects unsupported (e.g. binary) content types with `WEB_UNSUPPORTED_CONTENT_TYPE`.
 
-`validateFetchApprovalUrl()` exposes network-free URL syntax, length, credentials, and literal-IP checks to permission consumers. Hostname resolution remains exclusively in the provider after consent, where the result is enforced and pinned rather than reused as an authorization token.

 Direct `HttpFetchProvider` construction may inject an `HttpFetchResolver` for alternate trusted assemblies and deterministic tests. That resolver must reject every non-public destination before returning addresses; the shipped plugin always uses the built-in public-address resolver.

+The cache opens the `session_projcache` storage domain in the new `per-record` layout, added to the json backend: one version-stamped document per session at `<root>/session_projcache/sessions/<id>.json`, owned by the storage stack — `storage` / `storage-json` / `storage-domain` live in the shared base bundle alongside the cache, and the cache itself is a plain domain consumer again. Every shipped base-backed profile keeps the cache enabled, so the session producer records checkpoints independently of whether its current application exposes a listing interface; `sdk-minimal`, which does not use the base bundle, remains outside this composition. The cache never consults the persistence layer: no `locate`, no dependency on which backend is mounted.
 
 Reads and writes share ONE coherent state: every read (`cachedSnapshot`) is a synchronous lookup in the domain's in-memory tables (zero I/O), and every write queues on the domain's per-unit write chain, mutating memory only after durability — no direct disk reads that could lag the throttled writes. The cache keeps every other responsibility: checkpoint fold, write policy (turn/end + disposal mandatory, count/interval throttle), fail-soft durability, and the listing read. `cachedSnapshot(meta)` is synchronous. The cache runs no cold-refold ladder (that would require reading the session log, which belongs to the persistence layer); a consumer that needs a guaranteed cold snapshot refolds from the log itself.

 - Per-session write isolation: each throttled write replaces only that session's small document, removing the global write amplification. The domain write chain serializes writes, so a newer cut never lands before an older one; domain close drains in-flight writes.
 - Listing is a synchronous in-memory read; a session without a record document simply lacks the projection column.
+- ACP, headless, SDK, and Web sessions publish cache rows for later consumers. The log-leading durability barrier may flush a covered prefix at the cache cadence and split otherwise coalesced JSONL runs; recorded profile snapshots preserve that assembled persistence behavior.
 - The per-record contract scopes failure: a malformed or stale-version document reads as an absent record at open, so one bad file never bricks the cache, and a checkpoint schema bump discards stale sessions per record instead of rejecting the whole domain.
 - No migration: the cache is derived data, never an authority. An obsolete cache (any earlier format) is never read — the first cold read refolds from the log and writes the current format.
 - The cache record is bound to the same log lifecycle as before: the stored `{createdAt, cwd}` identity guards against a recreated id.

 The automation-only ACP stdio application as a `dsh` profile bundle over [`dsh-base`](../base/README.md). It inherits the base's disabled module-HMR policy; its patch sets the coding-agent persona and default model route, mounts an app-owned zero-option command provider, and starts [`dsh-acp`](../../acp/acp/README.md) only after that provider accepts the invocation. `dsh --profile acp --help` therefore writes help and exits without claiming stdin or stdout.
 
-The startup provider binds stdin EOF to the launcher's bounded successful shutdown. ACP connection close, SIGINT, and SIGTERM drain the bridge-owned agents and the root profile tree before exit.

The cache checkpoints each persisted one-shot session for later consumers; its durability barrier flushes each covered log prefix before publishing the cache row and may split otherwise coalesced JSONL runs.
 
 After the Loader settles, the runner reads the shared [`ctx.agentDefaultModel`](../../core/agent-default-model/README.md), creates one fresh persisted Agent through `ctx.agents`, submits the task as an ordinary user message, and waits for quiescence. It flushes the Session before folding the owned durable event interval, writes the last non-empty assistant text to stdout, and requests exit through the launcher-provided `ctx.appExit` host hook ([`dsh-cmdline`](../../boot/cmdline/README.md)) (final `turn/end` completed → 0, otherwise 1). A terminal `error` reason also writes its code and message to stderr; successful runs keep stderr empty. The process opens no listening port. The task text is this app's command line: the ordinary `headless-startup` provider ([`src/startup.ts`](src/startup.ts)) injects `ctx.cmdlineArgs` ([`dsh-cmdline`](../../boot/cmdline/README.md)), reads the positional argument of `dsh --profile headless "task"`, prints the app's `--help`, and provides `headlessStartup`; the runner injects that service and reads its task from lazy config. A missing or whitespace-only task is rejected before the runner activates.

 Loader 结算后，runner 读取共享的 [`ctx.agentDefaultModel`](../../core/agent-default-model/README.zh.md)，通过 `ctx.agents` 创建一个全新的持久化 Agent（智能体），将任务作为普通用户消息提交，并等待完全停稳。它对 Session 执行 flush 后再汇总自身持有的持久化事件区间，将最后一条非空 assistant 文本写入 stdout，再经启动器提供的 `ctx.appExit` 宿主钩子（[`dsh-cmdline`](../../boot/cmdline/README.zh.md)）请求退出（最终 `turn/end` 完成 → 0，否则为 1）。最终结束原因为 `error` 时，还会将 code 与 message 写入 stderr；成功运行时 stderr 保持为空。进程不会打开监听端口。任务文本就是这个应用的命令行：普通 `headless-startup` 提供方（[`src/startup.ts`](src/startup.ts)）注入 `ctx.cmdlineArgs`（[`dsh-cmdline`](../../boot/cmdline/README.zh.md)），读取 `dsh --profile headless "task"` 的位置参数、打印应用自己的 `--help`，并提供 `headlessStartup`；runner 注入该服务，再从惰性配置中读取任务。缺失或只有空白的任务会在 runner 激活前被拒绝。

 The SDK stdio application as a `dsh` profile bundle over [`dsh-base`](../base/README.md). It inherits the base's disabled module-HMR policy; its patch sets the coding-agent persona, mounts an app-owned zero-option command provider, and starts [`dsh-sdk-jsonrpc-server`](../../sdk/server/README.md) only after that provider accepts the invocation. `dsh --profile sdk --help` therefore writes help and exits without claiming stdin or stdout. The standalone [`sdk-minimal`](../sdk-minimal/README.md) bundle reuses the same startup provider and supplies its own profile name.
 
-The startup provider binds stdin EOF to the launcher's bounded successful shutdown. SDK protocol `shutdown`, SIGINT, and SIGTERM retain their owning server or launcher paths; disposal drains the root profile tree and persistence. Stdout is reserved for newline-delimited JSON-RPC frames. The bundle disables model-generated session titles because the SDK exposes no title surface; deterministic fallback titles remain durable without an auxiliary model request. It also keeps the base projection cache disabled: the SDK protocol exposes no session-listing surface, and the cache's write-behind would force session-log flushes at cache-chosen times, changing the durable JSONL batching this profile's keyless replay fixtures pin.

Subject: [PATCH 079/155] fix(ui-workspace): keep blank new sessions outside
 the fold quota

Keep five non-blank rows stable while the selected blank New Session is provisional, and derive the overflow count from the rows still hidden.

Fixes #2841

 ### Session folding and view order
 
-Each Workspace persists one browser-local open state: closed means zero Session rows and open means up to five. When more Sessions exist, **Show more** reveals the remainder only for the current mount; closing the whole Workspace clears this transient expansion, so reopening returns to five. The current Session's group opens automatically only when the user has not already stored an explicit state for that Workspace. Creating a Session from a Workspace row opens the target group before starting the Session, keeping the new row visible when state propagation completes. After a ready Workspace baseline changes, the browser removes expansion, order, and observed-timestamp records for ids absent from that baseline while retaining the Ungrouped and flat-list accounts.
+Each Workspace persists one browser-local open state: closed means zero Session rows and open means up to five non-blank rows plus the selected blank New Session as one provisional extra row. **Show more** reveals only the hidden remainder for the current mount; closing the whole Workspace clears this transient expansion, so reopening returns to the bounded folded projection. The current Session's group opens automatically only when the user has not already stored an explicit state for that Workspace. Creating a Session from a Workspace row opens the target group before starting the Session, keeping the new row visible when state propagation completes. After a ready Workspace baseline changes, the browser removes expansion, order, and observed-timestamp records for ids absent from that baseline while retaining the Ungrouped and flat-list accounts.
 
 The combined view menu offers **Manual** and **Last updated** in grouped and flat presentation, with one browser-local persisted order per account. A real Workspace initializes from `WorkspaceView.sessionIds`; Ungrouped and the cross-Workspace flat list initialize from recency and have no Host Session account. Entering Last updated performs one complete recency sort; a later user prompt or steer promotes that Session once, and dragging may edit the resulting order. Returning to Manual preserves the current order and only disables later activity promotion. Manual-mode drags for a real Workspace also write the Host Session account, while Ungrouped and flat-list drags and activity promotion remain browser-local. Flat rows omit an empty leading status slot because they have no parent hierarchy, while a visible status retains its slot.
 
-When New Session creation selects a blank Session, the browser promotes it once in both its grouped account and the flat-list account. This explicit creation promotion does not advance `updatedAt`; later drag ordering treats the blank like any other Session, and the first prompt does not undo a Manual-mode drag.
+When New Session creation selects a blank Session, the browser promotes it once in both its grouped account and the flat-list account. This explicit creation promotion does not advance `updatedAt`. While the Session remains blank, grouped folding does not charge it against the five non-blank rows; the first prompt returns it to the ordinary quota without undoing a Manual-mode drag.
 
 ### Drag and compact chrome
 
-Workspace hit testing uses the complete rendered group section, including visible Session rows. One insertion boundary is shared by the preceding group's lower half and the following group's upper half, and the indicator is an absolutely positioned line with a joined right-facing chevron that does not affect layout. A tree-body overlay draws the first boundary at the same negative offset outside the scrolling clip, so the leading chevron remains visible without moving the list. During a Workspace or Session drag, document-level `dragover` and `drop` handlers accept the native operation; if release occurs outside the Workspace list, `dragend` commits the last valid marker.

 Search is a header action while collapsed and expands across the title and trailing actions. An outside click collapses a query that is empty after trimming but retains a non-empty query; while the rail search gesture is still in flight the outside-click listener stays unmounted ([rail-search self-dismissal](../bug-fix/2026-08-18-rail-search-outside-click-self-dismissal.md)).

 - Workspace order is durable and shared through the Host, while grouping, open state, per-account Session view order, and query state remain browser-local presentation preferences.

 ## Testing
 
-Domain and Host tests cover durable Workspace moves, no-op and invalid anchors, restart recovery, full-order RPC responses, order frames, and one Workspace snapshot per Host-stream baseline. Runtime tests cover optimistic order, frame/response precedence, overlapping rejection rollback to Host-confirmed order, reconnect baselines, and New Session target priority. UI tests cover five-row folding, transient expansion reset, pruning persisted state after Workspace removal, order-preserving mode switches, one-time recent-update and New Session promotion, Manual drag retention after the first prompt, browser-local Ungrouped and flat-list drag persistence, hierarchy-free flat-row leading spacing, selected view indicators, expanded-section Workspace hit testing, an unclipped first insertion boundary, outside-list Workspace and Session drops, search collapse rules, and compact CSS dimensions.

 Shared Workspace browser and picker plugin. `WorkspaceBrowser` fills the sidebar's `sidebar.workspaces` slot, while `WorkspacePicker` fills the page-local Session Intent hero's `conversation.hero.workspace` slot; both surfaces use the same Workspace menu and add flow.
 
-The browser renders grouped or flat Session rows from the global runtime hooks and owns Workspace add/rename/reorder plus Session reorder. A Workspace remembers whether it is closed or showing Sessions; an open Workspace shows five Sessions by default, offers a transient **Show more** control for the remainder, and returns to five after the whole Workspace is closed and reopened. Creating a Session from a Workspace row first opens that group so the new row remains visible when the Session state arrives. Once the Workspace list baseline is ready, browser-persisted expansion and Session-order records retain only current Workspace ids plus Ungrouped and the flat-list account. View options combine grouping with one browser-persisted Session order per account: real Workspaces initialize from `WorkspaceView.sessionIds`, while Ungrouped and the cross-Workspace flat list initialize from recency. **Manual** and **Last updated** apply in either presentation. Entering Last updated performs a complete recency sort and later user prompts or steers promote their Session once, while entering Manual preserves every current position and disables later promotion. Dragging edits the current order in either mode; Manual-mode drags for real Workspaces also update the Host Session account, while Ungrouped and flat-list orders remain browser-local because neither has one Workspace account. Flat rows omit the empty leading status slot because they have no parent hierarchy, but retain it when a Session status is visible. Workspace drag order is Host-durable in either Session order mode.
+The browser renders grouped or flat Session rows from the global runtime hooks and owns Workspace add/rename/reorder plus Session reorder. A Workspace remembers whether it is closed or showing Sessions; an open Workspace shows five non-blank Sessions by default, keeps the selected blank **New Session** as one provisional extra row until its first prompt, offers a transient **Show more** control for the hidden remainder, and returns to that folded projection after the whole Workspace is closed and reopened. Creating a Session from a Workspace row first opens that group so the new row remains visible when the Session state arrives. Once the Workspace list baseline is ready, browser-persisted expansion and Session-order records retain only current Workspace ids plus Ungrouped and the flat-list account.

Dragging edits the current order in either mode; Manual-mode drags for real Workspaces also update the Host Session account, while Ungrouped and flat-list orders remain browser-local because neither has one Workspace account. A collapsed group resolves drag boundaries from its rendered rows and places the source ahead of intervening hidden rows, so the dragged row cannot disappear into the remainder. Flat rows omit the empty leading status slot because they have no parent hierarchy, but retain it when a Session status is visible. Workspace drag order is Host-durable in either Session order mode.
 
 Collapsed search is one header action beside the view and add actions. In the rail, add and search render as 36px controls on the shell's shared horizontal entry path. Activating search expands the field across the header; an outside click collapses only a query that is empty after trimming — except while the rail search gesture is still in flight (until focus lands in the input after the column slide), so the expanding click cannot dismiss the search it opened — while the clear control always resets and collapses it. A non-blank search query replaces either browsing mode with one flat result list: case-insensitive title and Workspace substring matches appear immediately, while a 250 ms debounced Host request adds ranked current-conversation content matches and snippets. The English search input and its defensive request path remove NUL, cap the query at the wire schema's 500 UTF-16 code units without splitting a surrogate pair, and preserve the existing debounce and cancellation behavior. Each new query aborts the preceding request; a failed content search leaves metadata matches visible with a warning. The list is capped at 20, asks the user to narrow broader queries, and opens the selected Session without clearing the query or jumping to a specific event.

 共享 Workspace 浏览器与选择器插件。`WorkspaceBrowser` 填充侧边栏的 `sidebar.workspaces` slot，`WorkspacePicker` 则填充页面局部 Session Intent 主视觉区的 `conversation.hero.workspace` slot；两个界面使用同一套 Workspace 菜单和添加流程。
 
-该浏览器通过全局运行时钩子将 Session 行渲染为分组或扁平形式，并负责 Workspace 添加／重命名／重排序以及 Session 重排序。每个 Workspace 会记住自身是关闭还是显示 Session；打开后默认显示五条 Session，其余条目通过临时的**展开其余**控件显示，而关闭并重新打开整个 Workspace 后会恢复为五条。从 Workspace 行创建 Session 时会先打开该分组，使 Session 状态到达后新行保持可见。Workspace 列表基线就绪后，浏览器持久化的展开状态与 Session 顺序记录只保留当前 Workspace id、Ungrouped 和单列表记账。视图选项把分组方式和每个记账各自的一份浏览器持久化 Session 顺序放在一起：真实 Workspace 从 `WorkspaceView.sessionIds` 初始化，Ungrouped 和跨 Workspace 的单列表则从最近更新时间顺序初始化。**手动排序**和**最近更新**在两种呈现方式下都可用。进入最近更新时会执行一次完整的时间排序，后续 user prompt 或 steer 会将对应 Session 置顶一次；进入手动排序则保留所有当前位置并停用后续置顶。两种模式下的拖拽都会编辑当前顺序；真实 Workspace 在手动模式下的拖拽还会更新 Host Session 记账，而 Ungrouped 和单列表因没有单一 Workspace 记账，其顺序始终只保存在浏览器本地。单列表没有父级层次，因此不显示空的左侧状态槽；Session 存在可见状态时仍保留该槽。无论采用哪种 Session 顺序，Workspace 拖拽顺序都由 Host 持久化。

 折叠搜索是视图和添加操作旁的一枚区头按钮。在轨道中，添加和搜索会渲染为沿外壳共用横向进入路径移动的 36px 控件。激活搜索后，输入框会扩展并占据区头；点击外部只会收起经清除首尾空白后为空的查询——但轨道搜索手势仍在进行期间（直至列滑动结束、焦点落入输入框）除外，这样触发展开的那次点击不会收起它刚打开的搜索——而清除控件总会重置并收起搜索。非空白查询会以单一扁平结果列表替代任一浏览模式：不区分大小写的标题和 Workspace 子串匹配项会立即显示，经 250 ms 防抖的 Host 请求则会加入经过排序的当前对话内容匹配项及其摘要片段。英文搜索输入框及其防御性请求路径会移除 NUL，将查询限制在传输 schema 规定的 500 个 UTF-16 代码单元内且不会拆分代理项对，并保留现有的防抖与取消行为。每次新查询都会中止前一个请求；内容搜索失败时，元数据匹配项仍会显示，同时给出警告。列表最多显示 20 条结果，并会在查询过宽时提示用户缩小范围；打开所选 Session 时既不会清除查询，也不会跳转至特定事件。

 - Per-session write isolation: each throttled write replaces only that session's small document, removing the global write amplification. The domain write chain serializes writes, so a newer cut never lands before an older one; domain close drains in-flight writes.

+- ACP, headless, SDK, and Web sessions publish cache rows for later consumers. The log-leading durability barrier may flush a covered prefix at the cache cadence and split otherwise coalesced physical JSONL runs; recorded profile snapshots re-pack the logical event stream so cache timing does not define fixture layout.
 - The per-record contract scopes failure: a malformed or stale-version document reads as an absent record at open, so one bad file never bricks the cache, and a checkpoint schema bump discards stale sessions per record instead of rejecting the whole domain.
 - No migration: the cache is derived data, never an authority. An obsolete cache (any earlier format) is never read — the first cold read refolds from the log and writes the current format.
 - The cache record is bound to the same log lifecycle as before: the stored `{createdAt, cwd}` identity guards against a recreated id.

 - per-record 契约把故障范围缩小到单记录：畸形或过期版本的文档在打开时读作"无此记录"，单个坏文件不会拖垮整个缓存；检查点 schema 升级按会话丢弃过期行，而不是拒绝整个域。
 - 无需迁移：缓存是派生数据，绝非权威。过时的缓存（任何更早格式）从不被读取——首次冷读从日志重折叠并写出当前格式。
 - 缓存记录仍绑定同一日志生命周期：存储的 `{createdAt, cwd}` 身份防止被重建的 id 误导。

Subject: [PATCH 082/155] ci(windows): raise coverage test timeout to 60s

After the 4-partition split, other PRs' windows coverage now fails on
process-bound subagent-acp tests timing out at 30s under self-hosted
concurrency. Give the coverage lane the same 60s per-test budget that the
earlier failover profile used.

Subject: [PATCH 085/155] test(subagent-acp): double the per-test timeout
 relative to default

These tests spawn real ACP child subprocesses. On contended self-hosted
Windows runners the default 30s budget times out. Instead of raising the
global coverage timeout, give this file 2x the configured default
(DSH_COVERAGE_TEST_TIMEOUT_MS) so it follows future default changes.

Subject: [PATCH 087/155] test(subagent-acp): skip stdout half-close tests on
 Windows

Windows anonymous pipes do not surface a child stdout EOF while the child
process stays alive. The three tests that simulate 'child closes protocol but
stays alive' therefore cannot be reproduced on Windows and hang until the
test timeout. Skip them on win32.

 `@deepseek-ai/dsh-tool-bash-persistent` consumes `ctx.terminals` and registers one `bash(command)` tool. It lazily creates one interactive shell per exact Agent and serializes that owner's calls. Cwd, exported variables, activated environments, functions, and background jobs persist. Random private markers delimit command output. Retained scrollback is paged backward to recover the command's original prefix; a dropped prefix is reported explicitly. A nonzero wrapped command appends `[exit code: N]`; a shell that dies before reporting that status instead appends `[shell exited: code N]`, `[shell killed by signal: SIG]`, or `[shell exited]` when the backend supplies neither. `maxOutputChars` bounds retained command output, while fixed diagnostics can extend the returned string. Timeout or cancellation closes the shell before another call can reuse uncertain state, and model-visible timeout/exit results disclose that reset. Cancellation always resets and discards the result, even when a complete status marker is already observable, so state changes the model never saw cannot survive. The configurable description defaults to persistence facts only, so network and package-mirror claims remain deployment-owned.
 
-`@deepseek-ai/dsh-tool-str-replace-editor` independently consumes `ctx.fs` and registers `str_replace_editor` with `view`, `create`, `str_replace`, and `insert`. It provides numbered text views, filtered two-level directory listings, unique literal replacement, canonical insertion boundaries, and bounded output. Paths are absolute; file views preserve content tabs so copied text remains valid literal replacement input; mutations preserve tabs outside the requested edit; and the public schema and failures use only `old_str`. The plugin can compose with persistent Bash, one-shot Bash, sandboxed Bash, or no shell.

 `dsh-system-prompt` accepts `includeHarnessIdentity: false`, while `dsh-agent-spine-demo` forwards that setting and accepts `toolBash: false`.

 ## Consequences
 
-Profiles can reproduce an external agent by configuring persona and descriptions while the underlying packages remain general. Persistent Bash requires an owning Agent and real PTY backend. Shell exit, timeout, or cancellation loses state. The editor delegates security and mutation policy to the mounted filesystem stack. A minimal Web agent retains Web permissions but must close its persistent shell before changing modes. Runtime-wheel consumers still need no Node installation; Linux wheels contain one executable, while macOS wheels also contain its private native helper.

 ## Tool
 
-The schema provides `view`, `create`, `str_replace`, and `insert` over absolute paths. File views use one-based line numbers and preserve content tabs, so displayed text remains valid literal replacement input; directory views omit hidden, dependency, and Python-cache entries and descend two levels. A metadata miss from `view`, `str_replace`, or `insert` records confirmed absence before returning `FS_NOT_FOUND`, so a later `create` can recover an externally deleted path through the mounted policy's guarded-create flow; absence never authorizes `str_replace` or `insert`. Replacement requires one unique literal match and reports errors only in the public `old_str` vocabulary. Insert follows the selected zero-based insertion boundary without adding an implicit trailing newline. Mutations preserve tabs outside the requested edit.

Replacement requires one unique literal match and reports errors only in the public `old_str` vocabulary. Command-specific fields accept `null` placeholders: execution treats them as omitted when the selected command does not use them, required fields remain required, `view_range: null` selects the full view, and `str_replace.new_str: null` is rejected so deletion requires omission. Insert follows its selected zero-based boundary without adding an implicit trailing newline. Mutations preserve tabs outside the requested edit.

   /** Delegate a self-contained task to a subagent (a separate agent that works in its own context) to offload focused, independent work — research, a scoped implementation, an analysis — so it does not consume this conversation's context. The subagent returns its result, not its intermediate steps. Give it a complete, standalone prompt: it does not see this conversation. This tool runs in the background by default, immediately returns a durable subagent id, and keeps the child conversation available for later turns. When that run settles, the runtime sends the parent a notice containing its outcome and any final assistant message; `send_message` starts a later turn in the same child conversation.

The subagent returns its result, not its intermediate steps. Give it a complete, standalone prompt: it does not see this conversation. This tool runs in the background by default, immediately returns a durable subagent id, and keeps the child conversation available for later turns. When that run settles, the runtime sends the parent a notice containing its outcome and any final assistant message; `send_message` starts a later turn in the same child conversation. Set `run_in_background: false` only when your next action depends on receiving the result. Child LLM selection is optional. Omit `provider`, `model`, and `reasoning_effort` to use configured child defaults and inherit compatible missing values from the parent Agent. Supply `provider` and `model` together after using `list_subagent_models` to inspect advertised routes and efforts. Changing the effective route without naming an effort uses the selected model's default effort. */

 `loadProfile` recognizes the exact installation-owned headless tuple (`dsh-base`, `dsh-web-app`, `dsh-headless`) and normalizes it to the shipped headless template while preserving every other manifest field. Extra, missing, or reordered bundle lists are user-owned and remain untouched.

+# Agent Note: headless streams provider reasoning to stderr
+
+Status: implemented
+
+English | [中文](2026-08-21-headless-reasoning-progress.zh.md)
+
+## Problem
+
+The one-shot headless runner waits for complete Agent quiescence before printing the final assistant text. Reasoning-capable providers already expose their reasoning as durable `assistant/chunk` events, but a long reasoned response leaves the terminal silent until the run completes. The final answer must remain the only stdout payload so command substitution and other consumers keep a stable result channel.
+
+The earlier [direct core entry-point decision](../architecture/2026-08-09-headless-direct-core-entry-point.md) required empty stderr on every successful run. That clause prevents live reasoning progress and is superseded by this note; its transport, durability, and completion decisions remain unchanged.
+
+## Decision
+
+`headless-runner` observes the exact Session it creates after startup quiescence and before submitting the task. Once the owned interval opens with `turn/start`, each non-empty `assistant/chunk.reasoning-delta` is written immediately to stderr. A contiguous reasoning phase starts with `dsh: reasoning:` on its own line; deltas retain provider order without token-boundary decoration. The first later non-reasoning chunk, a new turn, or listener disposal terminates the phase with one newline when the provider supplied none.
+
+This output is a transient projection of the existing durable Session event stream. The runner still derives final text and exit status from the flushed log rather than from progress-presentation state. The LLM adapter, agent loop, Session event types, persistence format, and SDK projections do not change.
+
+Reasoning progress is not TTY-gated and has no separate flag. A redirected stderr stream and a supervisor receive the same provider-reported content as an attached terminal. A successful run without reasoning still writes nothing to stderr; terminal model and driver errors keep their existing `dsh:` diagnostics after any open reasoning phase is terminated.
+
+## Verification
+
+The package test holds the Agent active after a reasoning delta and observes stderr before idle, then pins newline ownership for provider-terminated and unterminated phases plus terminal errors. The keyless product snapshot drives the shipped headless profile through a reasoning-plus-tool round and pins both stderr and the persisted Session. Built-bin acceptance sends `reasoning_content` through the native DeepSeek SSE adapter and requires reasoning on stderr while stdout remains the final answer.
+
+## Alternatives considered
+
+**Dump reasoning after quiescence.** Folding reasoning from the persisted log would preserve content but leave the terminal silent during the long-running interval that motivates the feature.
+
+**Wrap the LLM stream.** Tapping `ctx.llm.stream()` would place a presentation concern in the request path and duplicate the authoritative chunks that the agent loop already appends to the Session.
+
+**Print a spinner or periodic heartbeat.** A timer reports process liveness rather than provider progress, adds an interval policy, and still hides reasoning that the provider already supplies. Time before the first reasoning delta remains silent and can be addressed separately if providers buffer their first token.
+
+**Enable output only on a TTY or explicit flag.** Headless runs under CI and supervisors need the same progress signal, while implicit TTY-dependent behavior makes redirected runs differ from interactive runs. Callers that do not want reasoning logs redirect stderr.
+
+## Consequences
+
+Reasoning-capable successful runs now write provider-reported content to stderr, so log collectors may retain substantially more and potentially sensitive model output. Stdout remains one final assistant result, text-only success keeps stderr empty, errors remain line-separated, and no new configuration or durable format is introduced. Silence before the provider emits its first non-empty reasoning delta remains an explicit limitation.

+# Agent Note: headless 将提供方推理流式写入 stderr
+
+Status: implemented
+
+[English](2026-08-21-headless-reasoning-progress.md) | 中文
+
+## 问题
+
+一次性 headless runner 会等待 Agent（智能体）完全停稳，再打印最终 assistant 文本。具备推理能力的提供方已经把推理作为持久化的 `assistant/chunk` 事件暴露，但耗时较长的推理响应会让终端在运行完成前始终保持静默。最终答案必须继续作为 stdout 中唯一的载荷，使命令替换和其他消费方保持稳定的结果通道。
+
+此前的[直接使用核心服务入口决策](../architecture/2026-08-09-headless-direct-core-entry-point.zh.md)要求每次成功运行都保持 stderr 为空。该条款会阻止实时推理进度，因此由本 Agent Note 取代；其中关于传输、持久性与完成状态的其他决策保持不变。
+
+## 决策
+
+`headless-runner` 在启动工作完全停稳后、提交任务前，观察其创建的精确 Session。自身持有的区间以 `turn/start` 打开后，每个非空的 `assistant/chunk.reasoning-delta` 都会立即写入 stderr。一段连续推理以独占一行的 `dsh: reasoning:` 开始；各分片保持提供方顺序，不添加 token 边界装饰。之后出现首个非推理分片、新轮次或 listener dispose（资源释放）时，如果提供方没有输出末尾换行，runner 会用一个换行终止该段。
+
+该输出是既有持久化会话事件流的瞬时投影。runner 仍从 flush 后的日志而不是进度呈现状态推导最终文本与退出状态。LLM（大语言模型）适配器、agent loop（智能体循环）、Session 事件类型、持久化格式与 SDK 投影均不改变。
+
+推理进度不按 TTY 启用，也没有单独 flag。重定向的 stderr 流与监督进程会收到和已连接终端相同的提供方报告内容。没有推理内容的成功运行仍不会写入 stderr；终止态模型错误与驱动器错误继续在任何已打开推理段终止后输出既有的 `dsh:` 诊断。
+
+## 验证
+
+包测试在推理分片后保持 Agent 活跃，并在 idle 前观察 stderr；测试同时固定由提供方终止和未终止的推理段换行归属，以及终止态错误。无密钥产品快照通过包含推理与工具调用的轮次驱动随附 headless profile，并固定 stderr 与持久化 Session。构建后二进制验收通过原生 DeepSeek SSE（Server-Sent Events）适配器发送 `reasoning_content`，要求推理出现在 stderr，同时 stdout 仍只包含最终答案。

+**完全停稳后再输出推理。** 从持久化日志折叠推理能够保留内容，但在导致本功能产生的长时间运行区间内，终端仍会保持静默。
+
+**包装 LLM 流。** 截取 `ctx.llm.stream()` 会把呈现职责放入请求路径，并重复处理 agent loop 已经追加到 Session 的权威分片。
+
+**打印 spinner 或周期性心跳。** 定时器报告的是进程存活状态，而不是提供方进度；它还会新增间隔策略，并继续隐藏提供方已经给出的推理。首个推理分片前的时间仍保持静默；如果提供方会缓冲首个 token，可以另行处理。
+
+**仅在 TTY 或显式 flag 下启用输出。** CI 与监督进程中的 headless 运行需要相同的进度信号，而隐式依赖 TTY 会让重定向运行与交互式运行产生差异。不需要推理日志的调用方可以重定向 stderr。
+
+## 后果
+
+具备推理能力的成功运行会把提供方报告的内容写入 stderr，因此日志收集器可能保留明显更多且可能敏感的模型输出。stdout 仍只包含一个最终 assistant 结果，没有推理内容的成功运行保持 stderr 为空，错误继续与推理内容分行，并且本决策不引入新配置或持久化格式。提供方发出首个非空推理分片前保持静默，这是明确的限制。

 The dsh one-shot bundle. [`cordis.patch.yml`](cordis.patch.yml) rides directly over [`dsh-base`](../base/README.md): it inherits the base's disabled module-HMR policy, supplies the coding persona and tool mode, mounts Code Mode's worker as a core execution capability, and inserts this package's `headless-runner` plugin (config `{task}`, resolved from the injected `headlessStartup` provider). It mounts no Host, HTTP server, Web runtime, or browser plugin.
 
-After the Loader settles, the runner reads the shared [`ctx.agentDefaultModel`](../../core/agent-default-model/README.md), creates one fresh persisted Agent through `ctx.agents`, submits the task as an ordinary user message, and waits for quiescence. It flushes the Session before folding the owned durable event interval, writes the last non-empty assistant text to stdout, and requests exit through the launcher-provided `ctx.appExit` host hook ([`dsh-cmdline`](../../boot/cmdline/README.md)) (final `turn/end` completed → 0, otherwise 1). A terminal `error` reason also writes its code and message to stderr; successful runs keep stderr empty. The process opens no listening port. The task text is this app's command line: the ordinary `headless-startup` provider ([`src/startup.ts`](src/startup.ts)) injects `ctx.cmdlineArgs` ([`dsh-cmdline`](../../boot/cmdline/README.md)), reads the positional argument of `dsh --profile headless "task"`, prints the app's `--help`, and provides `headlessStartup`; the runner injects that service and reads its task from lazy config. A missing or whitespace-only task is rejected before the runner activates.
+After the Loader settles, the runner reads the shared [`ctx.agentDefaultModel`](../../core/agent-default-model/README.md), creates one fresh persisted Agent through `ctx.agents`, submits the task as an ordinary user message, and waits for quiescence. Each non-empty provider reasoning delta from that Agent is written to stderr as it arrives under a `dsh: reasoning:` heading; consecutive deltas remain one section, and the runner terminates the section before later output when the provider supplied no trailing newline. It then flushes the Session before folding the owned durable event interval, writes the last non-empty assistant text to stdout, and requests exit through the launcher-provided `ctx.appExit` host hook ([`dsh-cmdline`](../../boot/cmdline/README.md)) (final `turn/end` completed → 0, otherwise 1).

 ## Known Limitations and Deferred Work
 
 - **One submitted task only** — the runner has no interactive follow-up surface; it waits through any work the Agent completes before returning to idle and prints the last non-empty assistant message in that interval.
+- **No pre-token heartbeat** — stderr remains silent until the provider emits a non-empty reasoning delta; a provider that delays its first streamed token exposes no earlier progress signal.
 - **`ctx.appExit` is launcher-owned** — booting the headless profile outside the `dsh` launcher fails loud at activation until the host provides the exit request.

 ## Decision
 
-`headless-runner` observes the exact Session it creates after startup quiescence and before submitting the task. Once the owned interval opens with `turn/start`, each non-empty `assistant/chunk.reasoning-delta` is written immediately to stderr. A contiguous reasoning phase starts with `dsh: reasoning:` on its own line; deltas retain provider order without token-boundary decoration. The first later non-reasoning chunk, a new turn, or listener disposal terminates the phase with one newline when the provider supplied none.
+`headless-runner` observes the exact Session it creates after startup quiescence and before submitting the task. Once the owned interval opens with `turn/start`, each non-empty `assistant/chunk.reasoning-delta` is written immediately to stderr. A contiguous reasoning phase starts with `dsh: reasoning:` on its own line; deltas retain provider order without token-boundary decoration. Reasoning block boundaries and usage metadata keep that phase open; a later non-reasoning block or output delta, stream finish, new turn, or listener disposal terminates it with one newline when the provider supplied none.
 
 This output is a transient projection of the existing durable Session event stream. The runner still derives final text and exit status from the flushed log rather than from progress-presentation state. The LLM adapter, agent loop, Session event types, persistence format, and SDK projections do not change.

 ## Verification

+The package test holds the Agent active after a reasoning delta and observes stderr before idle, then pins newline ownership for provider-terminated and unterminated phases plus terminal errors. The owner-local product expectation drives the shipped headless profile through a reasoning-plus-tool round and pins both stderr and the persisted Session. Recorded-session replay reconstructs expected stderr from scalar and packed chunk rows, closes sections on packed text and tool-call output, and uses the raw run log before fixture path tokenization in record modes. Built-bin acceptance sends `reasoning_content` through the native DeepSeek SSE adapter and requires reasoning on stderr while stdout remains the final answer.

+# Agent Note: Exact Web per-Turn token usage
+
+Status: implemented
+
+English | [中文](2026-08-24-web-per-turn-token-usage.zh.md)
+
+## Problem
+
+Web Chat exposes cumulative session token usage near the composer, but that value cannot explain the cost of one completed Turn. A paged history window may begin inside a Turn, retries may consume several model calls, streaming and final events may repeat one attempt's usage, and optional cache fields do not prove an exact total. Displaying a partial subtotal as Turn usage would make recorded provider facts look more complete than they are.
+
+## Decision
+
+The shared `TokenUsage` value carries optional `totalTokens` for one model call. Adapters publish it only from an exact provider total or authoritative aggregate prompt and output counters. DeepSeek checks its prompt-plus-completion aggregate against any wire total, and pi-ai preserves its provided total.
+
+Token-meter owns a browser-safe pure Turn-local fold over durable session events, shared with its retry-aware cumulative usage projection. `step/start` and `llm/retry-started` open actual attempts; a final assistant message replaces the same attempt's streaming sample; terminal failures, retries, and step boundaries close attempts without double counting. Every started attempt must close with safe non-negative integer usage and an exact total. Optional cache, reasoning, and route aggregates appear only when every contributing attempt reports them, and reasoning remains a subset of output.
+
+Web Chat selects a Turn only when its loaded match window includes `turn/start`, passes that complete durable-event window to the token-meter fold, and renders the result. A complete, exact result appears through a local-state `DisclosureRow` above the existing actions; incomplete or contradictory evidence produces no row. Chat owns no token-accounting state machine.
+
+## Alternatives considered
+
+**Subtract neighboring cumulative session values.** Rejected because pagination, compaction, retry coverage, and projection completeness can make adjacent values incomparable; subtraction would infer data that no call reported.
+
+**Publish historical per-Turn values through a new client session projection.** Rejected because the loaded per-Turn view already has the durable attempt events it needs, while a history-growing projection would add transport, persistence, and versioning costs. Reusing token-meter's pure fold keeps one accounting owner without adding another wire value.
+
+**Show known buckets without an exact total.** Rejected because a lower-bound subtotal presented in a completed Turn footer is indistinguishable from a complete bill.
+
+## Consequences
+
+New provider records can expose exact per-Turn accounting without a new transport or persisted UI state. Older sessions and adapters without enough evidence simply omit the disclosure. Model routes disappear as a group when any billed attempt lacks attribution, while trustworthy token totals remain visible.
+
+Focused adapter, token-meter fold/projection, component, pagination, and assembled Web replay tests pin total preservation, retry-attempt separation, fail-closed validation, optional-field omission, interaction, and full-window publication. The cumulative projection and exact Turn fold now share token-meter ownership; the projection remains a whole-log bucket view, while the fold alone makes the stricter exactness and completeness claim required by the disclosure.

+# Agent Note: Web 单轮次精确 token 用量
+
+Status: implemented
+
+[English](2026-08-24-web-per-turn-token-usage.md) | 中文
+
+## Problem
+
+Web Chat 在编辑框附近显示会话累计 token 用量，但该值无法解释一个已完成轮次的消耗。分页历史窗口可能从轮次中间开始，重试可能消耗多次模型调用，流式事件与最终事件可能重复携带同一次 attempt 的用量，而可选 cache 字段也不能证明精确总量。将局部小计显示成轮次用量，会让已记录的提供方事实显得比实际更完整。
+
+## Decision
+
+共享 `TokenUsage` 值为一次模型调用携带可选的 `totalTokens`。适配器只从提供方精确总量，或权威的提示词与输出聚合计数发布该字段。DeepSeek 会将提示词加输出的聚合值与协议提供的总量核对，pi-ai 则保留其提供的总量。
+
+token-meter 拥有一份可安全用于浏览器的纯轮次局部 fold，并与其具备重试感知能力的累计用量投影共享记账所有权。`step/start` 与 `llm/retry-started` 打开真实 attempt；最终 assistant 消息替换同一 attempt 的流式样本；终止失败、重试与步骤边界关闭 attempt，且不会重复计数。每个已开始的 attempt 都必须以安全的非负整数用量和精确总量关闭。只有每个参与聚合的 attempt 都报告时，才会显示可选的 cache、推理与路由聚合值；推理仍是输出的子集。
+
+Web Chat 只选择已加载匹配窗口包含 `turn/start` 的 Turn，将该完整的持久事件窗口交给 token-meter fold，再渲染结果。完整且精确的结果通过现有 actions 上方、仅保留本地状态的 `DisclosureRow` 显示；证据不完整或矛盾时不显示该行。Chat 不拥有 token 记账状态机。
+
+## Alternatives considered
+
+**对相邻的会话累计值做减法。** 不采用，因为分页、压缩、重试覆盖范围与投影完整性可能让相邻值无法比较；减法会推断任何调用都未报告的数据。
+
+**通过新的客户端会话投影发布历史单轮次值。** 不采用，因为已加载的单轮次视图已经拥有所需的持久 attempt 事件，而随历史增长的投影会增加传输、持久化与版本成本。复用 token-meter 的纯 fold，可以在不新增 wire 值的前提下保持唯一记账所有方。
+
+**缺少精确总量时仍显示已知 bucket。** 不采用，因为在已完成轮次 footer 中展示的下界小计与完整账单无法区分。
+
+## Consequences
+
+新的提供方记录无需新增传输接口或持久化 UI 状态，即可显示精确的单轮次记账。证据不足的旧会话与适配器只会省略 disclosure。任一计费 attempt 缺少归属时，模型路由会整体消失，可信 token 总量仍可显示。
+
+定向的适配器、token-meter fold／投影、组件、分页与组装 Web 回放测试固定了总量保留、重试 attempt 分离、fail-closed 校验、可选字段省略、交互与完整窗口发布。累计投影与精确 Turn fold 现在同归 token-meter 所有；投影仍是完整日志的 bucket 视图，只有 fold 会作出 disclosure 所需的更严格精确性与完整性声明。

Usage chunks are counted even when a request later fails; a final assistant-message usage replaces the streaming sample from the same model attempt instead of double-counting it. A matching `llm/retry-started` boundary ends that replacement scope, so a retry with the same `(turn, step)` contributes a new billed attempt. Reasoning remains an output subdivision. The single last-sample slot relies on a session-log ordering property: once a later step reports usage, a legal log never reports usage for an earlier step again.

+Token-meter also owns the browser-safe pure fold from one complete Turn's durable events to exact attempt and Turn usage. `step/start` and `llm/retry-started` open real attempts; final message usage replaces that attempt's streaming sample; terminal failures, retries, and step boundaries close it. Missing lifecycle evidence, unsafe counts, or contradictory exact totals fail closed. Presentation consumers select a complete Turn window and render the result; they do not define a second accounting state machine.
 
 `contextPressure` carries optional `pressureTokens` — the newest provider-reported prompt size, summing uncached input plus cache reads and writes — optional `projectedTokens`, and optional `contextWindow` from the newest `request/context` record. Both figures stay absent until a provider reports usage; capacity stays absent for a route whose adapter advertises none. Output is excluded, so `pressureTokens` holds still while a turn streams and steps forward when the next request reports its usage.

The [packed session-history transport decision](2026-08-15-packed-session-history-transport.md) reuses this vocabulary for a bounded lossless wire interval without changing those event semantics.
 
 The JSONL backend packs each durable append batch. Raw `compression: 'none'` and default Zstandard framing carry the same logical storage records; selecting raw mode for reviewable fixtures does not disable packing. Repository replay readers and normalizers decode the shared row format instead of maintaining snapshot-specific codecs.

+# Agent Note: Carry packed chunk rows through session history
+
+Status: implemented
+
+English | [中文](2026-08-15-packed-session-history-transport.zh.md)
+
+## Problem
+
+`session.history` and `subagent.history` serve a bounded logical Session-event interval to remote clients. Provider streams can place hundreds of thousands of token-sized `assistant/chunk` events in one incomplete tail. Expanding every persisted row and then serializing every logical event repeats the same envelope on the wire; expanding every record again in the browser recreates the same object fan-out before the conversation fold joins the text.
+
+The transport must remain lossless. Session sequence numbers are pagination and reconnect evidence; exact token boundaries remain useful to diagnostics and non-UI API consumers; live streaming, durable export, replay, and model-history derivation continue to require the canonical event stream. A server-side transcript projection that discards completed-step chunks would make the API's evidence depend on one UI policy.
+
+## Decision
+
+History methods return `records: HistoryRecord[]` plus inclusive `fromSeq` and exclusive `toSeq` watermarks. An ordinary record carries `{event, view?}`. Consecutive same-block Assistant delta events carry `{chunks: ChunkRow}` using the shared lossless codec from [the packed JSONL decision](2026-07-26-packed-chunk-rows-by-default.md). The page is selected from logical events before packing, so message-aligned pagination remains independent of physical persistence layout.
+
+The wire schema validates every row, rejects unsafe reconstruction, and requires the records to cover `[fromSeq, toSeq)` exactly without gaps or overlaps. The watermarks, not the number or visible seq adjacency of browser fold inputs, own older-page stitching, reconnect repair, and live-event deduplication. `session.history` and `subagent.history` share the same response schema.
+
+The ordinary browser UI does not decode a packed row into one object per token. It coalesces a row into at most two `assistant/chunk` inputs while preserving accumulated content, the first non-empty token timestamp, and a later first non-whitespace visibility timestamp when those boundaries differ. Tool-call rows retain call identity, name presence, joined argument fragments, and first-token timing. Other API consumers may call `decodeStorageRecord()` when exact token boundaries are required.
+
+Live `session/event` frames remain individual events. Session persistence, raw export, replay, model-history derivation, and the canonical in-memory log are unchanged.
+
+## Measured result
+
+A production-sized private session sample was measured without retaining or committing its content. Its tail page contained 416,756 logical events. The lossless packed response used 696 top-level records, including 116 packed rows.
+
+| Representation | Top-level records | JSON bytes | gzip bytes | Brotli bytes |
+| --- | ---: | ---: | ---: | ---: |
+| Raw logical events | 416,756 | 69,433,638 | 4,190,226 | 1,972,998 |
+| Completed-step projection candidate | 228,129 | 38,427,209 | 2,324,688 | 957,350 |
+| Lossless packed history | 696 | 6,362,724 | 1,154,206 | 528,145 |
+
+Packing reduced uncompressed JSON by 90.8% relative to raw logical events and by 83.4% relative to the lossy completed-step projection candidate. Brotli output was 73.2% smaller than raw and 44.8% smaller than that projection candidate. These figures describe this sample rather than a protocol guarantee; savings scale with the length and regularity of delta runs.
+
+## Alternatives considered
+
+**Discard completed-step chunks on the Host.** This lowers logical event count but makes transport semantics depend on the current transcript policy, removes exact evidence from all consumers, and still sends every retained incomplete-step token as a separate envelope. The measured packed response is smaller while remaining lossless.
+
+**Send packed rows and expand every member in the browser.** This removes repeated JSON envelopes on the network but recreates hundreds of thousands of event objects, fold matches, and temporary arrays before producing the same accumulated UI state.
+
+**Rely on HTTP content encoding.** gzip and Brotli reduce bytes on the network but do not remove repeated JSON parsing, validation, allocation, and fold work. Packed rows remain substantially smaller after both encodings in the measured sample.
+
+**Page directly over physical persistence rows.** This could also avoid logical expansion in a cold Host read, but page cuts depend on append-origin messages and replacement provenance rather than backend row boundaries. The current decision keeps the API independent of JSONL, SQLite, and future persistence layouts.
+
+**Return only assembled Assistant snapshots.** The [assembled-messages-only rejection](../../rejected/simplification/2026-06-20-assembled-assistant-messages-only.md) remains applicable: event families outside finalized messages carry user-visible and diagnostic state, and incomplete steps need their actual accumulated chunks.
+
+## Consequences
+
+History responses preserve every logical event while reducing wire bytes, client JSON objects, and ordinary conversation-fold work for long delta runs. Pagination and reconnect logic use explicit raw interval watermarks, so compact browser inputs do not create false gaps. Existing consumers must switch from `events` to the `HistoryRecord` union and choose compact UI folding or exact decoding explicitly.
+
+Cold persisted history is still decoded into the complete logical `SessionEvent[]` before the Host selects and repacks a page. This decision therefore improves transport and browser work, not the Host's cold-read decode memory. Eliminating that expansion requires a persistence-neutral message-boundary index or a separate streaming page reader and remains a distinct optimization.
+
+Historical replay no longer reproduces one UI update per original token. The browser already installs history in a batch rather than animating past tokens; content and timing boundaries used by the settled view remain preserved. Live streaming behavior is unchanged.

+# Agent Note: 在会话历史中传输打包分片行
+
+Status: implemented
+
+[English](2026-08-15-packed-session-history-transport.md) | 中文
+
+## 问题
+
+`session.history` 与 `subagent.history` 会向远程客户端提供一段有界的逻辑会话事件区间。提供方流可能在一个未完成尾部中产生数十万个 token 大小的 `assistant/chunk` 事件。先展开每条持久化行，再序列化每个逻辑事件，会在协议中重复相同信封；浏览器再次展开每条记录，则会在 conversation 折叠拼接文本之前重建同样的对象扩散。
+
+传输必须保持无损。会话序号是分页与重连证据；精确 token 边界对诊断和非 UI API 消费方仍然有用；实时流式传输、持久导出、回放与模型历史派生仍然需要规范事件流。如果由服务端 transcript 投影丢弃已完成步骤的分片，API 证据就会取决于一项 UI 策略。
+
+## 决策
+
+历史方法返回 `records: HistoryRecord[]`，以及包含端 `fromSeq` 与不包含端 `toSeq` 水位。普通记录携带 `{event, view?}`。连续且属于同一块的 Assistant delta 事件使用[打包 JSONL 决策](2026-07-26-packed-chunk-rows-by-default.zh.md)中的共享无损编解码器，携带 `{chunks: ChunkRow}`。系统先从逻辑事件中选择页面，再执行打包，因此按消息对齐的分页不依赖物理持久化布局。
+
+协议 schema 校验每一行，拒绝不安全的重建，并要求记录无间隙、无重叠地精确覆盖 `[fromSeq, toSeq)`。更早页面拼接、重连修复与实时事件去重以水位为准，而不以浏览器折叠输入的数量或可见 seq 邻接关系为准。`session.history` 与 `subagent.history` 共用相同的响应 schema。
+
+普通浏览器 UI 不会把打包行解码成每个 token 一个对象。它会把一行合并成最多两个 `assistant/chunk` 输入，同时保留累计内容、首个非空 token 时间戳，以及这两个边界不同时较晚出现的首个非空白可见时间戳。工具调用行保留调用身份、名称存在性、拼接后的参数片段与首 token 时间。其他 API 消费方在需要精确 token 边界时可以调用 `decodeStorageRecord()`。
+
+实时 `session/event` 帧仍是单个事件。会话持久化、原始导出、回放、模型历史派生与规范内存日志均不改变。
+
+## 测量结果
+
+测量使用了一份生产规模的私有会话样本，未保留或签入其内容。其尾页包含 416,756 个逻辑事件。无损打包响应使用 696 条顶层记录，其中包含 116 条打包行。
+
+| 表示 | 顶层记录数 | JSON 字节 | gzip 字节 | Brotli 字节 |
+| --- | ---: | ---: | ---: | ---: |
+| 原始逻辑事件 | 416,756 | 69,433,638 | 4,190,226 | 1,972,998 |
+| 已完成步骤投影候选 | 228,129 | 38,427,209 | 2,324,688 | 957,350 |
+| 无损打包历史 | 696 | 6,362,724 | 1,154,206 | 528,145 |
+
+与原始逻辑事件相比，打包使未压缩 JSON 减少 90.8%；与有损的已完成步骤投影候选相比减少 83.4%。Brotli 输出相对原始形式减少 73.2%，相对该投影候选减少 44.8%。这些数字描述该样本，并非协议保证；收益随 delta run 的长度与规律性变化。
+
+## 曾考虑的替代方案
+
+**在 Host 丢弃已完成步骤的分片。** 这会减少逻辑事件数，但会让传输语义取决于当前 transcript 策略，从所有消费方移除精确证据，同时仍把保留的未完成步骤 token 逐个装入信封。实测打包响应在保持无损的同时更小。
+
+**发送打包行，再在浏览器展开每个成员。** 这会移除网络上的重复 JSON 信封，却会在生成相同累计 UI 状态之前，重建数十万个事件对象、折叠匹配与临时数组。
+
+**只依赖 HTTP 内容编码。** gzip 与 Brotli 会减少网络字节，但不会移除重复的 JSON 解析、校验、分配与折叠工作。在实测样本中，打包行经过这两种编码后仍然显著更小。
+
+**直接按物理持久化行分页。** 这还可以避免冷 Host 读取时的逻辑展开，但页面切分取决于追加来源消息与替换 provenance，而不是后端行边界。当前决策让 API 保持对 JSONL、SQLite 与未来持久化布局的独立性。
+
+**只返回组装后的 Assistant 快照。** [仅保留组装消息的否决记录](../../rejected/simplification/2026-06-20-assembled-assistant-messages-only.zh.md)仍然适用：final message 之外的事件族承载用户可见状态与诊断状态，未完成步骤也需要其实际累计分片。
+
+## 后果
+
+历史响应保留每个逻辑事件，同时减少长 delta run 的协议字节、客户端 JSON 对象与普通 conversation 折叠工作。分页与重连逻辑使用显式原始区间水位，因此紧凑浏览器输入不会产生伪间隙。现有消费方必须从 `events` 切换到 `HistoryRecord` 联合，并明确选择紧凑 UI 折叠或精确解码。
+
+冷持久历史仍会先解码成完整的逻辑 `SessionEvent[]`，Host 再选择页面并重新打包。因此，本决策改善的是传输与浏览器工作，不是 Host 冷读取的解码内存。消除该展开需要提供方无关的消息边界索引或单独的流式页面读取器，属于另一项优化。
+
+历史回放不再为每个原始 token 重现一次 UI 更新。浏览器本就会批量安装历史，而不会为过去的 token 播放动画；settled view 使用的内容与计时边界仍会保留。实时流式行为不变。

 Packing reduced uncompressed JSON by 90.8% relative to raw logical events and by 83.4% relative to the lossy completed-step projection candidate. Brotli output was 73.2% smaller than raw and 44.8% smaller than that projection candidate. These figures describe this sample rather than a protocol guarantee; savings scale with the length and regularity of delta runs.
 
+The opt-in `packages/client/runtime/tests/history-transport.perf.client.ts` benchmark constructs the same logical-event, ordinary-event, and delta-run cardinalities from synthetic content. `DSH_SNAPSHOT=replay pnpm exec vitest run --config vitest.web.perf.config.ts packages/client/runtime/tests/history-transport.perf.client.ts` reports wire sizes and Host/client timing under `HISTORY_TRANSPORT_PERF_RESULT`. The manual performance inventory does not run in CI and carries no machine-dependent timing assertions; structural assertions pin the fixture cardinalities, compact input count, and identical final state from its two-consumer Assistant fold fixture.
+
 ## Alternatives considered
 
 **Discard completed-step chunks on the Host.** This lowers logical event count but makes transport semantics depend on the current transcript policy, removes exact evidence from all consumers, and still sends every retained incomplete-step token as a separate envelope. The measured packed response is smaller while remaining lossless.

 ## 曾考虑的替代方案
 
 **在 Host 丢弃已完成步骤的分片。** 这会减少逻辑事件数，但会让传输语义取决于当前 transcript 策略，从所有消费方移除精确证据，同时仍把保留的未完成步骤 token 逐个装入信封。实测打包响应在保持无损的同时更小。

 Packing reduced uncompressed JSON by 90.8% relative to raw logical events and by 83.4% relative to the lossy completed-step projection candidate. Brotli output was 73.2% smaller than raw and 44.8% smaller than that projection candidate. These figures describe this sample rather than a protocol guarantee; savings scale with the length and regularity of delta runs.

Heap measurements force garbage collection before three runs and report the median peak observed after each major Host construction/serialization or Client parse/validation/preparation/fold stage, relative to the same initialized benchmark state. They do not measure process RSS and can miss transients within a sampled stage.

 ## Problem
 
-`session.history` and `subagent.history` serve a bounded logical Session-event interval to remote clients. Provider streams can place hundreds of thousands of token-sized `assistant/chunk` events in one incomplete tail. Expanding every persisted row and then serializing every logical event repeats the same envelope on the wire; expanding every record again in the browser recreates the same object fan-out before the conversation fold joins the text.
+`session.history` and `subagent.history` serve a bounded logical Session-event interval to remote clients. Provider streams can place hundreds of thousands of token-sized `assistant/chunk` events in one incomplete tail. Expanding every persisted row and then serializing every logical event repeats the same envelope on the wire and makes browser parsing and validation process that repetition before conversation replay can begin.
 
 The transport must remain lossless. Session sequence numbers are pagination and reconnect evidence; exact token boundaries remain useful to diagnostics and non-UI API consumers; live streaming, durable export, replay, and model-history derivation continue to require the canonical event stream. A server-side transcript projection that discards completed-step chunks would make the API's evidence depend on one UI policy.

 History methods return `records: HistoryRecord[]` plus inclusive `fromSeq` and exclusive `toSeq` watermarks. An ordinary record carries `{event, view?}`. Consecutive same-block Assistant delta events carry `{chunks: ChunkRow}` using the shared lossless codec from [the packed JSONL decision](2026-07-26-packed-chunk-rows-by-default.md). The page is selected from logical events before packing, so message-aligned pagination remains independent of physical persistence layout.

-The ordinary browser UI does not decode a packed row into one object per token. It coalesces a row into at most two `assistant/chunk` inputs while preserving accumulated content, the first non-empty token timestamp, and a later first non-whitespace visibility timestamp when those boundaries differ. Tool-call rows retain call identity, name presence, joined argument fragments, and first-token timing. Other API consumers may call `decodeStorageRecord()` when exact token boundaries are required.
+The browser calls the shared `decodeStorageRecord()` codec before handing history to `ConversationNodeAssembler`. Every packed member becomes its exact original `assistant/chunk` event, including `seq`, timestamp, chunk type, block index, text or argument fragment, call identity, and optional-name presence. A registered `ConversationNodeDefinition` therefore receives one `match()` call per historical delta and folds accepted matches with the same start/update sequence it observes for live events. Packing changes transport encoding without changing the public Definition replay semantics.
 
 Live `session/event` frames remain individual events. Session persistence, raw export, replay, model-history derivation, and the canonical in-memory log are unchanged.

 ## Alternatives considered
 
 **Discard completed-step chunks on the Host.** This lowers logical event count but makes transport semantics depend on the current transcript policy, removes exact evidence from all consumers, and still sends every retained incomplete-step token as a separate envelope. The measured packed response is smaller while remaining lossless.
 
-**Send packed rows and expand every member in the browser.** This removes repeated JSON envelopes on the network but recreates hundreds of thousands of event objects, fold matches, and temporary arrays before producing the same accumulated UI state.
+**Coalesce a packed run before registered Definitions see it.** This reduces browser event objects and fold calls, but an open `ConversationNodeDefinition` may count deltas, inspect their individual `seq` or timestamps, or derive state from fragment boundaries. Equal accumulated text does not make those state machines equivalent, so the transport cannot change their replay input cardinality.
 
-**Rely on HTTP content encoding.** gzip and Brotli reduce bytes on the network but do not remove repeated JSON parsing, validation, allocation, and fold work. Packed rows remain substantially smaller after both encodings in the measured sample.

The current decision keeps the API independent of JSONL, SQLite, and future persistence layouts.

 ## Consequences
 
-History responses preserve every logical event while reducing wire bytes, client JSON objects, and ordinary conversation-fold work for long delta runs. Pagination and reconnect logic use explicit raw interval watermarks, so compact browser inputs do not create false gaps. Existing consumers must switch from `events` to the `HistoryRecord` union and choose compact UI folding or exact decoding explicitly.
+History responses preserve every logical event while reducing wire bytes, Host response serialization and heap, and browser JSON parsing and validation for long delta runs. Pagination and reconnect logic use explicit raw interval watermarks, so packed transport records do not create false gaps. Existing direct consumers must switch from `events` to the `HistoryRecord` union and decode packed rows before event-level processing.
 
 Cold persisted history is still decoded into the complete logical `SessionEvent[]` before the Host selects and repacks a page. This decision therefore improves transport and browser work, not the Host's cold-read decode memory. Eliminating that expansion requires a persistence-neutral message-boundary index or a separate streaming page reader and remains a distinct optimization.
 
-Historical replay no longer reproduces one UI update per original token. The browser already installs history in a batch rather than animating past tokens; content and timing boundaries used by the settled view remain preserved. Live streaming behavior is unchanged.
+Browser history replay still allocates and folds one event per original token, so this decision does not reduce Definition match/update count or settled-history heap and may add a small decode-time peak while packed records and expanded events coexist.

+**在已注册 Definition 看到打包 run 前先进行合并。** 这会减少浏览器事件对象与折叠调用，但开放的 `ConversationNodeDefinition` 可能统计 delta、检查各自的 `seq` 或时间戳，或者根据片段边界派生状态。累计文本相同不代表这些状态机等价，因此传输不能改变其回放输入数量。
 
-**只依赖 HTTP 内容编码。** gzip 与 Brotli 会减少网络字节，但不会移除重复的 JSON 解析、校验、分配与折叠工作。在实测样本中，打包行经过这两种编码后仍然显著更小。

-历史响应保留每个逻辑事件，同时减少长 delta run 的协议字节、客户端 JSON 对象与普通 conversation 折叠工作。分页与重连逻辑使用显式原始区间水位，因此紧凑浏览器输入不会产生伪间隙。现有消费方必须从 `events` 切换到 `HistoryRecord` 联合，并明确选择紧凑 UI 折叠或精确解码。

 Packing reduced uncompressed JSON by 90.8% relative to raw logical events and by 83.4% relative to the lossy completed-step projection candidate. Brotli output was 73.2% smaller than raw and 44.8% smaller than that projection candidate. These figures describe this sample rather than a protocol guarantee; savings scale with the length and regularity of delta runs.

Heap measurements force garbage collection before three runs and report the median peak observed after each major Host construction/serialization or Client parse/validation/decoding/fold stage, relative to the same initialized benchmark state. They do not measure process RSS and can miss transients within a sampled stage.

 ## Problem
 
-`session.history` and `subagent.history` serve a bounded logical Session-event interval to remote clients. Provider streams can place hundreds of thousands of token-sized `assistant/chunk` events in one incomplete tail. Expanding every persisted row and then serializing every logical event repeats the same envelope on the wire and makes browser parsing and validation process that repetition before conversation replay can begin.
+`session.page` serves a bounded logical Session-event interval to remote clients. Provider streams can place hundreds of thousands of token-sized `assistant/chunk` events in one incomplete tail. Expanding every persisted row and then serializing every logical event repeats the same envelope on the wire and makes browser parsing and validation process that repetition before conversation replay can begin.
 
 The transport must remain lossless. Session sequence numbers are pagination and reconnect evidence; exact token boundaries remain useful to diagnostics and non-UI API consumers; live streaming, durable export, replay, and model-history derivation continue to require the canonical event stream. A server-side transcript projection that discards completed-step chunks would make the API's evidence depend on one UI policy.
 
 ## Decision
 
-History methods return `records: HistoryRecord[]` plus inclusive `fromSeq` and exclusive `toSeq` watermarks. An ordinary record carries `{event, view?}`. Consecutive same-block Assistant delta events carry `{chunks: ChunkRow}` using the shared lossless codec from [the packed JSONL decision](2026-07-26-packed-chunk-rows-by-default.md). The page is selected from logical events before packing, so message-aligned pagination remains independent of physical persistence layout.

The page is selected from logical events before packing, so message-aligned pagination remains independent of physical persistence layout.
 
-The wire schema validates every row, rejects unsafe reconstruction, and requires the records to cover `[fromSeq, toSeq)` exactly without gaps or overlaps. The watermarks, not the number of transport records, own older-page stitching, reconnect repair, and live-event deduplication. `session.history` and `subagent.history` share the same response schema.
+The generated Remote decoder validates the response fields, and the shared row decoder rejects malformed rows and unsafe sequence or timestamp reconstruction. `SessionEventStream` expands the records before passing them to `RemoteJournalStream`; the journal therefore checks page continuity, pagination joins, reconnect repair, and live-event deduplication against the original event sequence numbers. The durable address in the page request selects either an ordinary Session or an authorized direct subagent child without a second history protocol.
 
-The browser calls the shared `decodeStorageRecord()` codec before handing history to `ConversationNodeAssembler`. Every packed member becomes its exact original `assistant/chunk` event, including `seq`, timestamp, chunk type, block index, text or argument fragment, call identity, and optional-name presence. A registered `ConversationNodeDefinition` therefore receives one `match()` call per historical delta and folds accepted matches with the same start/update sequence it observes for live events. Packing changes transport encoding without changing the public Definition replay semantics.

 ## Consequences
 
-History responses preserve every logical event while reducing wire bytes, Host response serialization and heap, and browser JSON parsing and validation for long delta runs. Pagination and reconnect logic use explicit raw interval watermarks, so packed transport records do not create false gaps. Existing direct consumers must switch from `events` to the `HistoryRecord` union and decode packed rows before event-level processing.
+History responses preserve every logical event while reducing wire bytes, Host response serialization and heap, and browser JSON parsing and validation for long delta runs. The journal validates continuity after exact decoding, so packed transport records do not create false gaps. `SessionEventStream` consumers continue to receive ordinary event entries; direct `session.page` consumers must read the `SessionHistoryRecord` union and decode packed rows before event-level processing.
 
 Cold persisted history is still decoded into the complete logical `SessionEvent[]` before the Host selects and repacks a page. This decision therefore improves transport and browser work, not the Host's cold-read decode memory. Eliminating that expansion requires a persistence-neutral message-boundary index or a separate streaming page reader and remains a distinct optimization.

 传输必须保持无损。会话序号是分页与重连证据；精确 token 边界对诊断和非 UI API 消费方仍然有用；实时流式传输、持久导出、回放与模型历史派生仍然需要规范事件流。如果由服务端 transcript 投影丢弃已完成步骤的分片，API 证据就会取决于一项 UI 策略。
 
 ## 决策
 
-历史方法返回 `records: HistoryRecord[]`，以及包含端 `fromSeq` 与不包含端 `toSeq` 水位。普通记录携带 `{event, view?}`。连续且属于同一块的 Assistant delta 事件使用[打包 JSONL 决策](2026-07-26-packed-chunk-rows-by-default.zh.md)中的共享无损编解码器，携带 `{chunks: ChunkRow}`。系统先从逻辑事件中选择页面，再执行打包，因此按消息对齐的分页不依赖物理持久化布局。

-浏览器会先调用共享的 `decodeStorageRecord()` 编解码器，再把历史交给 `ConversationNodeAssembler`。每个打包成员都会还原为完全一致的原始 `assistant/chunk` 事件，包括 `seq`、时间戳、chunk 类型、block 索引、文本或参数片段、调用身份，以及可选名称是否存在。因此，已注册的 `ConversationNodeDefinition` 会对每个历史 delta 收到一次 `match()` 调用，并按实时事件所具有的同一 start／update 顺序折叠已接受的 match。打包只改变传输编码，不改变公共 Definition 的回放语义。

+历史响应保留每个逻辑事件，同时减少长 delta run 的协议字节、Host 响应序列化与堆占用，以及浏览器 JSON 解析与校验工作。Journal 会在精确展开后校验连续性，因此打包传输记录不会产生伪间隙。`SessionEventStream` 消费方继续收到普通事件条目；直接调用 `session.page` 的消费方必须读取 `SessionHistoryRecord` 联合，并在逐事件处理前解码打包行。
 
 冷持久历史仍会先解码成完整的逻辑 `SessionEvent[]`，Host 再选择页面并重新打包。因此，本决策改善的是传输与浏览器工作，不是 Host 冷读取的解码内存。消除该展开需要提供方无关的消息边界索引或单独的流式页面读取器，属于另一项优化。

 `@deepseek-ai/dsh-api-session-controller` owns the Host `ctx.sessionController` service and the generated Client `ctx.remote.session` namespace. It serves Session list, search, creation, model selection, rename, fork, prompt, attachment, queue, cancellation, message-aligned history, live log following, and Host-wide control state.
 
-History pages and follow event frames carry only raw `SessionWireEvent` values. Tool arguments, result content, failures, and `tool/result.data.meta` pass through unchanged; the controller does not resolve a Tool definition, run a presenter, or attach UI data.
+History pages carry `records`: ordinary records contain a raw `SessionWireEvent`, while consecutive same-block `assistant/chunk` deltas use the Session package's lossless packed-row encoding. `SessionEventStream` expands packed rows member-for-member before publishing a page to the Client Session object layer, so replay still observes every original event and sequence number. Follow frames remain raw individual events. Tool arguments, result content, failures, and `tool/result.data.meta` pass through unchanged; the controller does not resolve a Tool definition, run a presenter, or attach UI data.
 
 Each endpoint states its activation policy. List, search, attachment, history pages, and log following can inspect persistence without activating an Agent; queue mutation and cancellation require the corresponding live state; model, rename, and prompt commands may explicitly resume an ordinary Session. Create and fork are the only operations that create a new Agent. The service applies one preset-aware resume policy and subagent ownership fence to its own methods and to the Typert Agent and Session lookups used by other Remote namespaces.

 每个 endpoint 都声明自己的激活策略。列表、搜索、附件、历史页和日志跟随可以在不激活 Agent 的情况下检查 persistence；queue 变更和取消要求对应 live 状态仍然存在；模型、重命名和 prompt 命令可以显式恢复普通 Session。只有 create 和 fork 会创建新 Agent。该服务把同一套感知 preset 的恢复策略和 subagent ownership fence 同时用于自身方法，以及其他 Remote namespace 使用的 Typert Agent 与 Session lookup。

 Each unary call validates positional inputs, constructs the descriptor's exact named `args`, and sends it through `ctx.connection.rpc.call('/api', endpoint, ...)`. A generated stream method returns an `AsyncIterable` and opens one logical stream through an in-process Connection carrier when available, otherwise through the shared Gateway WebSocket. Generated cancellation-aware methods accept a final optional `AbortSignal`; the Client combines it with the contribution mount lifetime before invoking the carrier. Unary results and every stream item are validated before reaching application code. Withdrawing a contribution removes its descriptors and methods together, aborts in-flight calls and streams, and makes retained method handles reject.
 
-`ctx.remote.$stream()` returns a single-consumer `RemoteStream` spanning physical carrier generations. It permits one immediate retry while the Host remains available, otherwise waits for the next connected Host generation, and annotates each item with its physical generation. The domain consumer validates and accepts each generation's opening value; business and protocol failures remain terminal. `RemoteSnapshotStream` adds one opening snapshot followed by deltas, while `RemoteJournalStream` adds follow-before-page opening, cursor deduplication, pagination, reconnect catch-up, and gap repair. Disposing any stream cancels its requests and resolves after the active iterator is fully stopped.
+`ctx.remote.$stream()` returns a single-consumer `RemoteStream` spanning physical carrier generations. It permits one immediate retry while the Host remains available, otherwise waits for the next connected Host generation, and annotates each item with its physical generation. The domain consumer validates and accepts each generation's opening value; business and protocol failures remain terminal. `RemoteSnapshotStream` adds one opening snapshot followed by deltas. `RemoteJournalStream` adds follow-before-page opening, pagination, reconnect catch-up, and gap repair over domain-defined inclusive entry ranges; it removes complete duplicates and rejects gaps, inverted ranges, and partial overlaps. Disposing any stream cancels its requests and resolves after the active iterator is fully stopped.
 
 `ctx.remote.$on()` subscribes to one forwarded Host event. Its legal keys are exactly the Host assembly's forwarding selection, and the listener type is the owning package's own Cordis `Events` declaration, so no second signature can drift from it. Each subscription belongs to the calling fiber and disappears with it. The Client Remote service registers the `$events` pump as a Connection generation source when it activates, whether or not any `$on` listener exists. Browsers use Remote mux, while in-process compositions use `connection.rpc.open`; the `ready` item and `host.describe` jointly establish a Connection generation. Carrier failure, Remote stream failure, unexpected normal completion, a non-ready opening item, or a malformed event item ends that generation and lets Connection reopen it after backoff. Ordinary notifications run in registration order and isolate listener failures. Agent-scoped waterfalls let a listener return a result, call `next()`, or reject; Gateway returns that outcome through the existing HTTP unary carrier.

 `ctx.remote.$on()` 订阅一条被转发的 Host 事件。它的合法键恰好等于 Host 装配声明的转发选择，listener 类型就是事件所属包自己的 Cordis `Events` 声明，因此不存在会与之漂移的第二份签名。每个订阅归属发起调用的 fiber，并随该 fiber 一起消失。Client Remote 服务激活时就把 `$events` pump 注册为 Connection generation source，因此即使当前无 `$on` 订阅，它也会在 Connection 循环启动时打开。浏览器使用 Remote mux，进程内组合使用 `connection.rpc.open`；`ready` 项与 `host.describe` 共同建立一个 Connection generation。物理 carrier 失败、Remote stream error、意外正常结束、非 ready 首项或畸形事件项都会终止该 generation，由 Connection 退避后重开。普通通知按注册顺序运行并隔离 listener 失败；Agent-scoped waterfall 允许 listener 返回结果、调用 `next()` 或拒绝，Gateway 再通过现有 HTTP 一元载体回送该结果。

 `@deepseek-ai/dsh-api-session-controller` owns the Host `ctx.sessionController` service and the generated Client `ctx.remote.session` namespace. It serves Session list, search, creation, model selection, rename, fork, prompt, attachment, queue, cancellation, message-aligned history, live log following, and Host-wide control state.
 
-History pages carry `records`: ordinary records contain a raw `SessionWireEvent`, while consecutive same-block `assistant/chunk` deltas use the Session package's lossless packed-row encoding. `SessionEventStream` expands packed rows member-for-member before publishing a page to the Client Session object layer, so replay still observes every original event and sequence number. Follow frames remain raw individual events. Tool arguments, result content, failures, and `tool/result.data.meta` pass through unchanged; the controller does not resolve a Tool definition, run a presenter, or attach UI data.
+History pages and follow opening snapshots carry a discriminated `SessionHistoryRecord`. Both variants use `{ type, event }`: `type: 'event'` carries one raw `SessionWireEvent`, while `type: 'chunks'` carries one lossless `ChunkRowEvent` for consecutive same-block `assistant/chunk` deltas. Both inner values expose `type`, `seq`, `time`, and `data`, so the Client retains each accepted record as one `SessionEventLikeEntry` without record-by-record conversion. A packed event's `seq` and `time` identify its first member, and `data` retains the fragment and timestamp-gap arrays. Live follow frames remain individual `event` records. Tool arguments, result content, failures, and `tool/result.data.meta` pass through unchanged; the controller does not resolve a Tool definition, run a presenter, or attach UI data.
 
 Each endpoint states its activation policy. List, search, attachment, history pages, and log following can inspect persistence without activating an Agent; queue mutation and cancellation require the corresponding live state; model, rename, and prompt commands may explicitly resume an ordinary Session. Create and fork are the only operations that create a new Agent. The service applies one preset-aware resume policy and subagent ownership fence to its own methods and to the Typert Agent and Session lookups used by other Remote namespaces.
 
-The Client adapter exposes `SessionEventStream`, a Gateway `RemoteJournalStream` bound to one ordinary or direct-subagent address. It opens follow before the initial page, publishes only contiguous `replace`, `prepend`, and `append` changes, and repairs reconnect or sequence gaps through a tail page. A business, persistence, or unresolved continuity failure terminates the stream, while only physical carrier loss selects automatic resumption. `SessionControlStream` is a Gateway `RemoteSnapshotStream`; every generation opens with a complete process-local baseline, so reconnect replaces queue, jobs, and projection state instead of treating transient values as durable events.

 `@deepseek-ai/dsh-api-session-controller` 拥有 Host 的 `ctx.sessionController` 服务和生成的 Client `ctx.remote.session` namespace。它提供 Session 列表、搜索、创建、模型选择、重命名、fork、prompt、附件、queue、取消、按消息对齐的历史、live 日志跟随和 Host 范围 control 状态。
 
-历史页携带 `records`：普通记录包含原始 `SessionWireEvent`，连续且属于同一 block 的 `assistant/chunk` delta 使用 Session 包的无损打包行编码。`SessionEventStream` 会在向 Client Session 对象层发布页面前逐成员展开打包行，因此回放仍能观察到每个原始事件和序号。Follow frame 继续携带单个原始事件。工具参数、结果内容、失败信息和 `tool/result.data.meta` 原样通过；controller 不解析 Tool definition、不运行 presenter，也不附加 UI 数据。
+历史页与 follow opening snapshot 携带带判别字段的 `SessionHistoryRecord`。两个分支都使用 `{ type, event }`：`type: 'event'` 携带一个原始 `SessionWireEvent`，`type: 'chunks'` 则携带一个由连续且属于同一 block 的 `assistant/chunk` delta 组成的无损 `ChunkRowEvent`。两种内部值都公开 `type`、`seq`、`time` 与 `data`，因此 Client 无需逐 record 转换，就能把每条已接受 record 保留为一个 `SessionEventLikeEntry`。packed event 的 `seq` 与 `time` 表示首成员，`data` 保留 fragment 与 timestamp-gap 数组。实时 follow frame 继续携带单个 `event` record。工具参数、结果内容、失败信息和 `tool/result.data.meta` 原样通过；controller 不解析 Tool definition、不运行 presenter，也不附加 UI 数据。
 
 每个 endpoint 都声明自己的激活策略。列表、搜索、附件、历史页和日志跟随可以在不激活 Agent 的情况下检查 persistence；queue 变更和取消要求对应 live 状态仍然存在；模型、重命名和 prompt 命令可以显式恢复普通 Session。只有 create 和 fork 会创建新 Agent。该服务把同一套感知 preset 的恢复策略和 subagent ownership fence 同时用于自身方法，以及其他 Remote namespace 使用的 Typert Agent 与 Session lookup。
 
-Client adapter 提供 `SessionEventStream`，即绑定到一个普通 Session 或 direct subagent address 的 Gateway `RemoteJournalStream`。它在读取首个 page 前打开 follow，只发布连续的 `replace`、`prepend` 和 `append` 变更，并通过 tail page 修复重连或 seq 缺口。业务、persistence 或无法恢复的连续性错误会终止 stream，只有物理载体断开才触发自动恢复。`SessionControlStream` 是 Gateway `RemoteSnapshotStream`；每代都以完整的进程本地 baseline 开始，因此重连会替换 queue、jobs 和 projection 状态，而不会把瞬态值当作 durable event。

 Client Session owned transport windows, connection state, and pending interactions while also interpreting Assistant, Tool, message, command, compaction, retry, and turn-tail events in a centralized transcript fold. Adding one business node required changes to Session switches, history replay, indexes, caches, and React grouping; business identity, state evolution, and final presentation had no independent owner.
 
-The old path also placed running Assistant and Tool values outside the finalized flow. They entered the log-ordered node list only after settlement, so their React parent changed and remounted them even when the business ID and `key` remained stable. Full history loads, older prepends, live appends, and token streaming used separate update paths, leaving reference stability and local recomputation dependent on specialized caches spread across the client.
+Without target-neutral assembly, running Assistant and Tool values sit outside the finalized flow and enter the log-ordered node list only after settlement. Their React parent then changes and remounts them even when the business ID and `key` remain stable. Separate update paths for full history loads, older prepends, live appends, and token streaming also make reference stability and local recomputation depend on specialized caches spread across the client.
 
 Business events also use different correlation models. Tool has call IDs, Assistant correlates by turn and step, Compaction has its own lifecycle and checkpoint, and an Inbox splice represents one instantaneous state in a sequence. Keeping all these distinctions in one fold would make every business change pass through a global lookup and invalidate unrelated caches.
 
 ## Decision
 
-Client Runtime provides a target-neutral Conversation Node assembly engine. Business plugins register Event Definitions, and view plugins register per-Session View Builders. `ui-conversation` registers the first built-in Definitions and the `chat` builder; Session only submits the current contiguous Event window to the engine and publishes its snapshot instead of interpreting individual conversation businesses.

 ## Problem
 
-`session.page` serves a bounded logical Session-event interval to remote clients. Provider streams can place hundreds of thousands of token-sized `assistant/chunk` events in one incomplete tail. Expanding every persisted row and then serializing every logical event repeats the same envelope on the wire and makes browser parsing and validation process that repetition before conversation replay can begin.
+`session.page` and the opening `session.follow` snapshot serve a bounded logical Session-event interval to remote clients. Provider streams can place hundreds of thousands of token-sized `assistant/chunk` events in one incomplete tail. Expanding every persisted row and then serializing every logical event repeats the same envelope on the wire. Expanding a packed response at the Client boundary recreates the same event objects, journal entries, Location indexing, Definition matches, and State updates before conversation replay can finish.
 
-The transport must remain lossless. Session sequence numbers are pagination and reconnect evidence; exact token boundaries remain useful to diagnostics and non-UI API consumers; live streaming, durable export, replay, and model-history derivation continue to require the canonical event stream. A server-side transcript projection that discards completed-step chunks would make the API's evidence depend on one UI policy.
+The transport must remain lossless. Session sequence numbers are pagination and reconnect evidence; exact fragment boundaries and timestamps remain useful to diagnostics and non-UI API consumers; live streaming, durable export, replay, and model-history derivation continue to require the canonical event stream. Browser presentation does not require one allocated event object and one Definition callback per historical fragment when a Definition can fold the lossless run directly.
 
 ## Decision
 
-`session.page` returns `records: SessionHistoryRecord[]`. An ordinary record carries `{event}`. Consecutive same-block Assistant delta events carry `{chunks: ChunkRow}` using the shared lossless codec from [the packed JSONL decision](2026-07-26-packed-chunk-rows-by-default.md). The page is selected from logical events before packing, so message-aligned pagination remains independent of physical persistence layout.
+History pages and follow opening snapshots carry `records: SessionHistoryRecord[]`. An ordinary record is `{ type: 'event', event: SessionWireEvent }`; consecutive same-block Assistant delta events use `{ type: 'chunks', event: ChunkRowEvent }` and the shared lossless codec from [the packed JSONL decision](2026-07-26-packed-chunk-rows-by-default.md). The Host constructs the event-shaped value once when it packs the selected page. Its `type` is `chunkrow/text-chunks`, `chunkrow/reasoning-chunks`, or `chunkrow/tool-call-chunks`; `seq` and `time` identify the first member, while `data` retains the original fragment and timestamp-gap arrays. The explicit outer discriminator selects the record class without interpreting that detailed chunk kind. The page is selected from logical events before packing, so message-aligned pagination remains independent of physical persistence layout.
 
-The generated Remote decoder validates the response fields, and the shared row decoder rejects malformed rows and unsafe sequence or timestamp reconstruction. `SessionEventStream` expands the records before passing them to `RemoteJournalStream`; the journal therefore checks page continuity, pagination joins, reconnect repair, and live-event deduplication against the original event sequence numbers. The durable address in the page request selects either an ordinary Session or an authorized direct subagent child without a second history protocol.
+The generated Remote decoder validates the response fields. `SessionEventStream` passes the original wire records to `RemoteJournalStream` and supplies each record's inclusive logical sequence range: an event covers `[event.seq, event.seq]`, while a row covers `[event.seq, event.seq + memberCount - 1]`. The journal checks page continuity, pagination joins, reconnect repair, complete duplicates, partial overlaps, and live-event deduplication before publishing records. The durable address in the page request selects either an ordinary Session or an authorized direct subagent child without a second history protocol.
 
-The Client adapter calls the shared `decodeStorageRecord()` codec before publishing a page to the Session object layer. Every packed member becomes its exact original `assistant/chunk` event, including `seq`, timestamp, chunk type, block index, text or argument fragment, call identity, and optional-name presence. A registered `ConversationNodeDefinition` therefore receives one `match()` call per historical delta and folds accepted matches with the same start/update sequence it observes for live events. Packing changes transport encoding without changing the public Definition replay semantics.
+The Client narrows the accepted `SessionHistoryRecord[]` to `SessionEventLikeEntry[]` without allocating replacement entries. The outer `type` remains available to the journal, Session, and assembler; both variants carry an inner value with aligned `type`, `seq`, `time`, and `data` fields. `ChunkRowEvent` is Client history data, not a durable Session event: it is absent from `SessionEventMap`, `Session.events`, and `session/event`.
 
-Live `session.follow` frames remain individual events. Session persistence, raw export, replay, model-history derivation, and the canonical in-memory log are unchanged.
+Conversation accepts the same `{ type, event }` entries retained by Session. Definitions receive the inner `SessionEventLike`: `match()` and `update()` accept standard or packed values, while `start()` accepts only a standard `SessionEvent`; the assembler uses the outer discriminator to reject a packed start. Chat Assistant, Turn Tail, and Trajectory Assistant handle the three packed tags in their existing reducers. One row therefore remains one Client entry, Conversation input, and Match, while those reducers preserve scalar replay's final blocks, tool-call fields, first-token time, first-visible boundary, retry behavior, and interruption state.
+
+Live `session.follow` frames remain individual events and use the scalar path, so visible streaming cadence is unchanged. Session persistence, raw export, replay, model-history derivation, and the canonical in-memory log are unchanged.

 ## Alternatives considered
 
 **Discard completed-step chunks on the Host.** This lowers logical event count but makes transport semantics depend on the current transcript policy, removes exact evidence from all consumers, and still sends every retained incomplete-step token as a separate envelope. The measured packed response is smaller while remaining lossless.
 
-**Coalesce a packed run before registered Definitions see it.** This reduces browser event objects and fold calls, but an open `ConversationNodeDefinition` may count deltas, inspect their individual `seq` or timestamps, or derive state from fragment boundaries. Equal accumulated text does not make those state machines equivalent, so the transport cannot change their replay input cardinality.
+**Expand each packed row before the Session object layer.** This preserves one callback per historical delta but recreates the browser allocation, indexing, and fold costs that packed transport can avoid. Consumers that require scalar events can still call `decodeStorageRecord()` explicitly.
 
-**Rely on HTTP content encoding.** gzip and Brotli reduce bytes on the network but do not remove repeated JSON parsing and validation. Packed rows remain substantially smaller after both encodings in the measured sample, while exact browser replay retains the required allocation and fold work.
+**Put the raw row under a distinct `.chunks` payload.** This forces downstream consumers either to retain two payload field names or to allocate an aligned wrapper before assembly. The shared `.event` field preserves fast outer classification and one inner Definition path.

 ## Consequences
 
-History responses preserve every logical event while reducing wire bytes, Host response serialization and heap, and browser JSON parsing and validation for long delta runs. The journal validates continuity after exact decoding, so packed transport records do not create false gaps. `SessionEventStream` consumers continue to receive ordinary event entries; direct `session.page` consumers must read the `SessionHistoryRecord` union and decode packed rows before event-level processing.
+History responses preserve every logical event while reducing wire bytes, Host response serialization and heap, browser JSON parsing and validation, Client entry allocation, and Conversation dispatch for long delta runs. The journal validates logical ranges before publication, so packed records neither create false gaps nor hide partial overlap. Direct `session.page` consumers must switch on `SessionHistoryRecord.type` and explicitly expand `record.event.data` when they require one event per member.
 
 Cold persisted history is still decoded into the complete logical `SessionEvent[]` before the Host selects and repacks a page. This decision therefore improves transport and browser work, not the Host's cold-read decode memory. Eliminating that expansion requires a persistence-neutral message-boundary index or a separate streaming page reader and remains a distinct optimization.
 
-Browser history replay still allocates and folds one event per original token, so this decision does not reduce Definition match/update count or settled-history heap and may add a small decode-time peak while packed records and expanded events coexist. History installs as one batch rather than animating old tokens; live streaming behavior is unchanged.
+The default Client history path exposes `SessionEventLike`, so consumers that require only canonical durable events must remain on Host `Session.events`, `session/event`, or an explicit decode path. A Definition that consumes Assistant deltas maintains equivalent scalar and packed branches. Scalar deltas already received live remain scalar in the current window; online replacement with a packed row is separate work, while reopen and reconnect install packed history.

 This page defines the data model and the extension path for a business-owned Conversation node. The [Web Client architecture](web-client.md) places the subsystem between Client models and Slots; the [Conversation Node assembly decision](../../.agents/notes/implemented/architecture/2026-08-09-client-conversation-node-assembly.md) owns its rationale.
 
 ## Data model and ownership
 
-The Session Controller owns the contiguous loaded event window. `ui-conversation` observes that existing source and converts each entry to `{ event, view? }`; it never opens a second history stream. One `ConversationNodeAssembler` per Session applies every registered Definition and publishes an independent source for each registered view target.
+The Session Controller owns the contiguous loaded logical-event window. Each `SessionEventLikeEntry` is either `{ type: 'event', event: SessionEvent }` or `{ type: 'chunks', event: ChunkRowEvent }`; both inner events expose `type`, `seq`, `time`, and `data`. `ui-conversation` passes these entries to the assembler without opening a second history stream, converting records, or expanding packed members. One `ConversationNodeAssembler` per Session applies every registered Definition and publishes an independent source for each registered view target.
 
 | Concept | Owner and purpose |

-| Event Definition | A business package matches one event at a time, correlates it by stable `(kind, id)`, folds deterministic State, and optionally materializes one target node. |
-| Context | The engine-owned ordered Matches and current State for one `(kind, id)`. Update-only evidence may remain pending until pagination supplies its unique start. |

 Incremental events are supported. Prefer whole-value checkpoints when the producer can emit them cheaply, because they remain useful when the start is outside the loaded window. Each delta must carry the stable id and produce deterministic State when replayed in ascending log `seq`; it must not depend on live-only memory. If the current history window contains only updates, the assembler keeps a pending Context and builds no State until an older page supplies the start. If the product must render before the start is loaded, a terminal or checkpoint event must carry enough whole fallback state for the Definition to build that result directly; do not recover it by scanning unrelated events.
 
+Historical runs of consecutive same-block `assistant/chunk` deltas arrive as `chunkrow/text-chunks`, `chunkrow/reasoning-chunks`, or `chunkrow/tool-call-chunks`. Their top-level `seq` and `time` identify the first logical member, and their `data` retains each fragment and timestamp gap. These Client-only events can only be updates; `start()` receives a standard `SessionEvent`. A Definition that consumes Assistant deltas handles the relevant packed tags in the same `match()` and `update()` methods, while other Definitions return `null` without expanding the run.

Every scalar event or packed Assistant run in a multi-input Context carries or independently derives the same stable business id; `update` folds one Match into State and remains deterministically replayable by logical log `seq`.

-`ui-conversation` owns target-neutral Conversation assembly and the shared browser shell. It consumes Session Controller event feeds, exposes React-free registries and per-Session bindings through `ctx.uiConversation`, and contributes the `useConversation`, `useInput`, and `inputActions` standard props through `ctx.uiSession`. It also owns the per-session durable image URL cache: `ctx.uiConversation.imageUrl(sessionId, attachment)` resolves one session-authorized browser URL per attachment and revokes it with the Session binding, so every Conversation target shares one `session.attachment` read. Concrete targets such as Chat are separate packages that register their own Definitions, snapshot builders, Views, and renderers.
+`ui-conversation` owns target-neutral Conversation assembly and the shared browser shell. It consumes Session Controller `SessionEventLikeEntry` feeds, exposes React-free registries and per-Session bindings through `ctx.uiConversation`, and contributes the `useConversation`, `useInput`, and `inputActions` standard props through `ctx.uiSession`. It also owns the per-session durable image URL cache: `ctx.uiConversation.imageUrl(sessionId, attachment)` resolves one session-authorized browser URL per attachment and revokes it with the Session binding, so every Conversation target shares one `session.attachment` read. Concrete targets such as Chat are separate packages that register their own Definitions, snapshot builders, Views, and renderers.
 
 ## Conversation assembly
 
 `UiConversation.events` is the single registry for event Definitions, and `UiConversation.views` is the single registry for target snapshot builders. Both registries reject duplicate keys, preserve registration order, return idempotent disposers, and rebuild existing bindings when their contribution roster changes. `UiConversation.binding(bindingOrSessionId)` returns one identity-stable Conversation binding for the current Session Controller binding. It does not open another event source.
 
-The adapter converts each `SessionEventEntry` to a `{ event }` `ConversationEventInput` and preserves the raw Session event, including tool-result metadata. Contiguous append and prepend revisions use incremental assembly; replacement windows and revision gaps rebuild from the complete loaded window. The assembler owns Context matching, Turn/Step locations, target node materialization, target activity, and stable target sources. `ConversationSnapshot` contains only target-neutral views and active-target facts; Session lifecycle state remains in `SessionSnapshot`.
+The adapter passes each `SessionEventLikeEntry` directly to the assembler. Its outer `type` distinguishes scalar and packed records, while its inner `event` always exposes `type`, `seq`, `time`, and `data`; Definitions receive that inner `SessionEventLike`. Historical replace and prepend accept both entry variants, while live append accepts only `SessionLiveEventEntry`. Every Definition uses the same `match` and `update` methods for both event forms, while `start` receives only a standard event and the assembler rejects a packed start. Definitions that do not consume Assistant deltas return `null` for the packed tags. Replacement windows and revision gaps rebuild from the complete loaded window; contiguous append and prepend revisions use incremental assembly without expanding packed members. The assembler owns Context matching, Turn/Step locations, target node materialization, target activity, and stable target sources. `ConversationSnapshot` contains only target-neutral views and active-target facts; Session lifecycle state remains in `SessionSnapshot`.
 
 Target packages declaration-merge their snapshot and Location data maps, then register with `ctx.uiConversation.events.register(...)` and `ctx.uiConversation.views.register(...)`. A target reads its Session-owned source with `ctx.uiConversation.binding(binding).target(targetId)`. Registrations are Cordis effects and their returned disposers remove the contribution from the same registry.

-`ui-conversation` 拥有与 target 无关的 Conversation 组装和共享浏览器 shell。它消费 Session Controller event feed，通过 `ctx.uiConversation` 暴露不依赖 React 的 registry 与逐 Session binding，并通过 `ctx.uiSession` 提供 `useConversation`、`useInput` 和 `inputActions` 标准 props。它还拥有按会话的持久化图片 URL 缓存：`ctx.uiConversation.imageUrl(sessionId, attachment)` 为每个附件解析一个经会话授权的浏览器 URL，并随 Session binding 释放而撤销，因此所有 Conversation target 共享一次 `session.attachment` 读取。Chat 等具体 target 位于独立 package，由各自 package 注册 Definition、snapshot builder、View 和 renderer。

 ## Conversation 组装
 
 `UiConversation.events` 是 event Definition 的唯一 registry，`UiConversation.views` 是 target snapshot builder 的唯一 registry。两者都拒绝重复 key、保持注册顺序、返回幂等 disposer，并在 contribution roster 变化时重建现有 binding。`UiConversation.binding(bindingOrSessionId)` 为当前 Session Controller binding 返回 identity 稳定的 Conversation binding，不会另开 event source。
 
-adapter 将每个 `SessionEventEntry` 转换成 `{ event }` 形式的 `ConversationEventInput`，并保留原始 Session event，包括工具结果 metadata。连续 revision 的 append 和 prepend 使用增量组装；replace window 或 revision 断档从完整已加载窗口重建。assembler 拥有 Context 匹配、Turn/Step location、target node 物化、target activity 和稳定 target source。`ConversationSnapshot` 只包含与 target 无关的 View 与 active-target 事实；Session lifecycle 状态仍属于 `SessionSnapshot`。
+adapter 把每个 `SessionEventLikeEntry` 直接交给 assembler。外层 `type` 区分 scalar 与 packed record，内部 `event` 则统一公开 `type`、`seq`、`time` 与 `data`；Definition 接收这个内部 `SessionEventLike`。历史 replace 与 prepend 接受两种 entry，实时 append 只接受 `SessionLiveEventEntry`。两种 event 都使用 Definition 的同一组 `match` 与 `update` 方法，`start` 则只接收标准 event，assembler 会拒绝 packed start。不消费 Assistant delta 的 Definition 对 packed tag 返回 `null`。replace window 或 revision 断档从完整已加载窗口重建；连续 revision 的 append 和 prepend 使用增量组装，并且不展开 packed member。assembler 拥有 Context 匹配、Turn/Step location、target node 物化、target activity 和稳定 target source。`ConversationSnapshot` 只包含与 target 无关的 View 与 active-target 事实；Session lifecycle 状态仍属于 `SessionSnapshot`。
 
 target package 通过 declaration merge 扩展 snapshot 与 Location data map，再调用 `ctx.uiConversation.events.register(...)` 和 `ctx.uiConversation.views.register(...)`。target 通过 `ctx.uiConversation.binding(binding).target(targetId)` 读取其 Session-owned source。注册属于 Cordis effect，返回的 disposer 从同一个 registry 移除 contribution。

-Trajectory renders a turn-aware event ledger with selectable User, Assistant, Tool, and nested Subtool records. Thick rules mark Turn boundaries, compact inline markers identify Steps, and the main ledger keeps only index, event, and content; selection opens a local inspector for token usage, duration, Input, Output, and Timing. Durable image attachments in user input, assistant output, and tool results render through the `conversation.trajectory.images` gallery slot: a record without text labels its row with the image count, the inspector shows each image with the shared loading, retry, and lightbox behavior, and image URLs come from the Conversation-owned per-session cache, so Chat and Trajectory share one authorized read per attachment. Scrollable Summary regions keep their scrollbar thumbs transparent until the region is hovered or contains keyboard focus, without changing the reserved scroll geometry. A standalone compaction request appears chronologically in its own `Between turns` section, while a numbered compaction remains inside its owning turn. Long ledgers open at the current tail, load one older page when the user reaches the loaded range's top, and mount only the visible row window plus a small overscan; request-only separators share the next measurable virtual item, while semantic row keys and ARIA indexes survive prepends. Selection, timeline navigation, folding, search, and Request totals cover the currently loaded window. The ledger covers records with an explicit loading row until the initial tail is positioned. While an older prefix remains unloaded, a first-row control precedes the loaded records, loads one earlier page on click, and changes in place to a disabled loading status while that page is pending. A fixed Overview above the ledger projects real record start/duration timing from left to right; when earlier records remain unloaded and the viewport includes the loaded domain's start, a neutral ellipsis control identifies the omitted prefix and loads one earlier page without assigning unknown history fabricated duration. Assistant spans divide recorded TTFT from decoding, and a 500 ms hover reveals exact clock and duration details. Dragging an interval focuses the ledger on every record active at any point in that inclusive range, while clearing the selection restores the full loaded ledger. Wheel gestures zoom the time domain. A right-button click clears the selected interval, while a right-button drag pans an already zoomed viewport without changing it. The initial view and streaming updates stay at the tail; scrolling upward suspends following so new records do not interrupt inspection of earlier rows. Content-only stream frames preserve virtual row keys and heights, reuse measurements, and do not issue repeated tail-scroll writes. Completed replies retain assembled blocks, timing, and usage in Trajectory target State, while the shared Session window keeps the raw Events. Trajectory asks the conversation shell to float the composer over the full-height ledger, while its responsive vertical scrollers reserve the composer's live height so final rows remain reachable. Trajectory-owned Definitions assemble business records, including durable cancellation-finalized prefixes, chunk-only interruption fallbacks, and interrupted Tool records, from the shared Session window, so Trajectory neither reads nor changes the Chat conversation snapshot. The package provides no service and declares no Context merge; it registers target-specific Event Definitions, a Trajectory view builder, and one tab in the conversation's `'conversation.view'` slot ring. Its typed `trajectory` locale namespace owns every product-authored ledger, timeline, inspector, tooltip, and accessibility phrase; event content, tool names, identifiers, and provider diagnostics remain verbatim data.

 **Component copy rides the standard `t` seat; deep children take `t` as a plain prop** typed `XxxProps['t']`. The dictionary canon is unchanged: `zh satisfies Record<string, string>` is the key source and `en satisfies Record<XxxKey, string>` locks bilingual balance.
 
+**The built-in locale set is closed; the language catalog is extensible.** The package contributes only `zh` and `en`, and typed namespace registration continues to require that bilingual pair. An external client plugin adds a language through `ctx.effect(() => ctx.locale.addLanguage({ id, label, fallback }))` and contributes partial translations through the existing single-locale dictionary registration. An external language id is its BCP 47 tag for preference storage, dictionary lookup, browser matching, and `<html lang>`; the built-in `zh` definition retains its internal `zh-CN` document tag. Every added language names a registered fallback whose own definition supplies the next fallback, and the chain must terminate at `en`; unknown targets and cycles fail at registration. For each key, lookup walks that chain in the requested namespace, then repeats it in `common`, before displaying the key itself. The Host stores an open string preference; an unavailable saved id remains pending until its language registers, while removal returns an active selection to the available browser match or `en`. Catalog changes advance the `LocaleFace` revision so the Language row follows registration and disposal.
+
 **Zero-Cordis atoms (ui-primitives) take copy as required props.** `HoverCard`, structured Tool blocks, JSON/Markdown renderers, `ConnectionBanner`, and modal chrome remain runtime-independent; localized plugins pass complete dictionary-driven label objects from their own `t` seat and memoize cache-sensitive objects on the `t` identity. The removal of language-bearing defaults and the complete prop inventory are owned by the [locale-owned copy decision](2026-08-23-locale-owned-client-ui-copy.md).
 
 **Every product-authored UI phrase is translated.** Client fallbacks, design labels, trajectory inspection, accessibility names, and formatter units are dictionary-owned under the [locale-owned copy decision](2026-08-23-locale-owned-client-ui-copy.md). User/model/provider/wire text and protocol or code tokens remain verbatim data. Framework-free boot markup still runs before the locale service; the localized application replaces its product copy after activation.

The Client keeps Host settings persistence disabled on non-loopback pages, so their locale selection remains process-local even though Connection authenticates every API method. `locale/change` fires on switches, and the plugin points `<html lang>` at the active locale (`zh-CN`/`en`) on activation and on every switch. The service also owns the ns×locale dictionary registry (typed `register(ns, {zh, en})` checked against `LocaleNamespaceMap`, `bind(ns)`→`TranslateNS<ns>`; lookup chain ns → common → en → key), implements the slot system's `LocaleFace`, and installs itself through `ctx.slots.installLocale`, backing the framework-injected `t` standard seat (`Translate`/`TranslateNS` are ui-slots types; import them from there — this package only re-exports for dictionary owners' convenience).

+The package ships only `zh` and `en`. External client plugins add a selectable language with `ctx.effect(() => ctx.locale.addLanguage({ id, label, fallback }))` and add its dictionaries through the existing `register(ns, locale, dict)` form; unloading the definition removes it from the selector and returns an active selection to the available browser/default locale. An external id is a non-empty ASCII BCP 47-style tag used for persistence, dictionary lookup, browser matching, and `<html lang>`. Its fallback must already be registered, and the resulting chain must terminate at `en`; unknown targets, duplicate ids, and cycles fail at registration. For each key, lookup walks the chain in the requested namespace, repeats it in `common`, then displays the key. The typed `register(ns, { zh, en })` form remains checked against `LocaleNamespaceMap` and requires both built-in dictionaries. LocaleRuntime implements the slot system's `LocaleFace` and installs itself through `ctx.slots.installLocale`, backing the framework-injected `t` standard seat (`Translate`/`TranslateNS` are ui-slots types; import them from there — this package only re-exports them for dictionary owners).

 - **Registry-held text reads its translation once** — copy captured at registration time outside the slot render path (e.g. the `/model` command description in the command registry) keeps the language it was registered under until re-registration; slot-rendered copy follows switches live.

 The Settings Language row opened every first visit in Chinese: `LocaleRuntime` read `dsh.locale` from localStorage and fell straight back to `zh` when nothing was stored. The browser already states which languages its user reads — `navigator.languages` is that statement — and the app ignored it, so an English reader met a Chinese product and had to find a Chinese-labelled settings row to escape it. The fallback was doing two jobs at once: the last resort for an unresolvable locale, and the answer for every user who had simply never chosen.
 
-Reading the browser fixed the readers whose browser names a language this app ships, but left the residual case wrong: a browser asking for neither `zh` nor `en` (`fr`, `de`) still fell back to `zh`. Those readers are the least likely to read Chinese.
+Reading the browser fixes readers whose browser names a registered language, but the product still needs a stable residual when the current catalog has no match. With only the built-in catalog, a browser asking for neither `zh` nor `en` (`fr`, `de`) reaches that case, and those readers are the least likely to read Chinese.
 
 ## Decision
 
-**The provisional locale resolves through the browser, then `FALLBACK_LOCALE` (`en`); an explicit Host preference replaces it live.** `resolveInitialLocale()` in `packages/client/locale/src/client/index.ts` runs at service construction and expresses the browser/fallback order. The nonblocking settings lifecycle then applies optional `locale.preference` from `$DSH_HOME/settings.yaml`; absence leaves the browser-derived value active.
+**The provisional locale resolves through the browser, then `FALLBACK_LOCALE` (`en`); an explicit Host preference replaces it live.** `resolveInitialLocale()` in `packages/client/locale/src/client/index.ts` runs at service construction and after each language-catalog change, expressing the browser/fallback order over the definitions currently registered. The nonblocking settings lifecycle then applies optional `locale.preference` from `$DSH_HOME/settings.yaml`; absence leaves the browser-derived value active, while an unavailable saved id remains pending and takes effect if that language registers later.
 
-**One constant serves both the opening locale and the dictionary fallback, because the dictionaries are symmetric.** `FALLBACK_LOCALE` answers both "which language does the UI open in when the browser names none we ship" and "which dictionary backs a key the active locale misses". Those are different questions, and splitting them into two constants would be right if either answer had to differ — but every shipped `zh`/`en` pair declares identical key sets, so the fallback step always resolves and both answers are `en`. The residual case points at English rather than zh because a browser naming neither shipped language is the reader least likely to read Chinese. `scripts/locale-dictionary-parity.spec.ts` gates the symmetry the shared constant depends on: a key added to one side only fails that spec by name, instead of surfacing later as a bare key such as `list.aria` in a running UI.
+**One constant serves both the opening residual and the dictionary-chain terminus.** `FALLBACK_LOCALE` answers both "which language does the UI open in when the browser names none registered" and "where must every declared dictionary fallback chain end". Those are different questions, and splitting them into two constants would be right if either answer had to differ. External languages may contribute partial dictionaries and declare intermediate fallbacks; every chain still reaches `en`. Every built-in `zh`/`en` pair declares identical key sets, so its final fallback resolves, while `scripts/locale-dictionary-parity.spec.ts` rejects a key added to only one built-in side instead of letting it surface later as a bare key such as `list.aria` in a running UI.
 
-**Browser matching is on the primary subtag, over the ordered list.** `detectBrowserLocale()` walks `[...(navigator.languages ?? []), navigator.language]` and returns the first entry whose primary subtag names a shipped locale, so `zh-Hans-CN` and `zh-TW` both land on `zh` and `en-GB` on `en`, while a browser asking only for languages this app does not ship (`fr`, `de`) yields nothing and leaves `FALLBACK_LOCALE` in charge. `navigator.language` trails the list and covers its absence on hosts that ship a Navigator without `languages` — the DOM lib types it as always present, so that tolerance carries a narrow lint exception, the same environment-boundary distrust the `localStorage` guards already express.
+**Browser matching uses the registered catalog and the browser's ordered list.** `detectBrowserLocale()` walks `[...(navigator.languages ?? []), navigator.language]`. Each browser tag first matches a registered id exactly and then by primary subtag, so a registered `pt-BR` wins for that exact request, while `zh-Hans-CN` and an unmatched `zh-TW` land on the built-in `zh`, and `en-GB` lands on `en`. A browser asking only for unregistered languages (`fr`, `de` with the built-in catalog) yields nothing and leaves `FALLBACK_LOCALE` in charge. Registering or removing a language recomputes this provisional result. `navigator.language` trails the list and covers its absence on hosts that ship a Navigator without `languages`; tolerating that runtime omission follows the same environment-boundary distrust as the `localStorage` guards.
 
 **`window`, not `navigator`, is the browser test.** Node ≥ 21 exposes a global `navigator` reporting the machine's own language, so gating on `navigator` would let a node boot of the client tree resolve to the machine's language instead of the documented fallback. Gating on `window` keeps every non-browser run on `FALLBACK_LOCALE`.
 
 **An explicit choice is durable.** `setLocale` writes through the Host settings API, so a user who picked a language keeps it across browser origins and system languages that share the same DSH home. Nothing writes the detected locale back: detection is re-derived every boot and stays invisible to the “has the user chosen?” question.
 
-**`<html lang>` follows the resolved locale, and the served markup cannot.** `apps/web/index.html` is one static file serving every visitor, so whatever it declares is wrong for somebody: resolution happens in the client, after the document is parsed. The locale plugin therefore sets `document.documentElement.lang` from the active locale — once at activation, because detection or an adopted Host preference may already disagree with the markup, and again on every switch. The markup declares the product default (`en`) so the pre-boot document is not actively misleading. Assistive technology and browser features (pronunciation rules, translation offers, font fallback, spell check) read this attribute, so a stale value misreports the document language rather than merely looking untidy. The attribute carries a BCP 47 tag rather than the app's locale id: `zh` alone leaves the script ambiguous, so the shipped Chinese copy declares `zh-CN`.

The `fr-FR` scenario is the one that pins the fallback — an `en-US` browser would land on English under detection or fallback alike, so only an unshipped language distinguishes them, and the zh scenarios prove detection still overrides the fallback.

 - **A cordis config key for the fallback locale**: the deployment does not vary here — the fallback is the product's answer for "no signal at all", not a knob. Repo policy reserves `Config` fields for deployment-varying choices with a current consumer.
 - **Two constants, one for the opening locale and one for the dictionary fallback**: it separates two genuinely different questions, and would be required if the answers differed. They do not: the dictionaries are symmetric, so both are `en`, and a second constant would be two names for one value plus a rule nothing enforces. The symmetry itself is worth enforcing, so it is gated directly instead.
 - **Keeping `zh` as the dictionary fallback while opening in `en`**: it reads as the conservative choice, but with symmetric dictionaries it never resolves a key that `en` would not, so it buys nothing; and where it would matter — a key present only in `zh` — rendering Chinese text inside an otherwise English UI is worse than the bare key a reviewer would notice.

 ## Consequences
 
-- A first visit from an English browser lands in English, a Chinese browser in Chinese, and a browser naming neither lands in English rather than Chinese. The Language row still shows the same two self-described options, so the escape hatch is unchanged in either direction.
-- Dictionary resolution reverses direction: a key missing from the active locale now falls to `en`, not `zh`. With symmetric dictionaries no shipped key changes behavior, which is why the parity gate exists — it is the assumption that reversal rests on.
+- A first visit chooses the first registered language matched from the browser's ordered list. With only the built-in catalog, an English browser lands in English, a Chinese browser in Chinese, and a browser naming neither lands in English rather than Chinese; external registrations join the same Language row and matching process.
+- Dictionary resolution ends at `en`: a built-in `zh` miss reaches it directly, while an external language follows its declared per-key chain first. Symmetric built-in dictionaries keep shipped copy complete, which is why the parity gate exists.
 - `<html lang>` now reports the language on screen in both directions, which closes [#2160](https://github.com/deepseek-harness/deepseek-harness/issues/2160). A client that never activates the locale plugin keeps the served default, so the attribute degrades to the old static behavior rather than to a blank value.
 - Non-browser runs of the client tree (node boots, the non-jsdom unit lane) now open in `en`. Specs that assert shipped Chinese copy must set `setLocale('zh')` explicitly on the runtime they construct; a suite-level `usePinnedBrowserLanguages('zh-CN')` only works in files that also declare `@vitest-environment jsdom`, because without a `window` the detection path never reads `navigator` at all. Seven `*.client.spec.ts` files carried such a dead pin and were relying on the old `zh` fallback instead.
-- Detection cost is one array walk per service construction and no implicit settings write; an explicit Host preference may cause one live convergence after plugin activation.

-**开场 locale 与字典回落值共用一个常量，因为两侧字典是对称的。** `FALLBACK_LOCALE` 同时回答「浏览器未声明任何本应用提供的语言时，界面以哪种语言开场」与「当前 locale 的字典缺失某个 key 时由哪本字典兜住」。这是两个不同的问题，若其中任一答案必须不同，拆成两个常量才是对的——但每一对已提供的 `zh`／`en` 字典都声明了完全相同的 key 集合，因此回落这一步总能解析成功，两个答案都是 `en`。残余情形指向英文而非 `zh`，是因为一个声明了本应用都不支持的语言的浏览器，其读者最不可能读中文。`scripts/locale-dictionary-parity.spec.ts` 为这个共用常量所依赖的对称性设了门禁：只加在一侧的 key 会让该用例指名失败，而不是日后在运行中的界面里显现为形如 `list.aria` 的裸 key。

 ## Consequences
 
-- 来自英文浏览器的首访落在英文界面，中文浏览器落在中文界面，而两者皆未声明的浏览器落在英文而非中文界面。语言行依然呈现同样两个以自身语言自述的选项，两个方向的脱身通道都未改变。
-- 字典解析方向发生反转：当前 locale 缺失的 key 现在回落到 `en` 而非 `zh`。在字典对称的前提下，没有任何已提供的 key 行为发生变化——这正是那道对称性门禁存在的原因：它是这次反转所依赖的前提。
+- 首次访问会从浏览器的有序列表中选择第一个匹配的已注册语言。若目录中只有内置语言，英文浏览器进入英文界面，中文浏览器进入中文界面，两者皆未声明的浏览器则进入英文而非中文界面；外部注册项会加入同一个语言行与匹配过程。
+- 字典解析最终到达 `en`：内置 `zh` 缺失 key 时直接到达它，外部语言则先按自己声明的链逐 key 回落。内置字典对称性保证已提供的文案完整，这正是对称性门禁存在的原因。
 - `<html lang>` 现在在两个方向上都如实报告屏幕上的语言，这也关闭了 [#2160](https://github.com/deepseek-harness/deepseek-harness/issues/2160)。若某个客户端从未激活 locale 插件，则保留所服务的默认值，因此该属性退化为旧的静态行为，而不会退化为空值。
 - 客户端树的非浏览器运行（node 启动、非 jsdom 单测车道）现在以 `en` 开场。断言已提供中文文案的用例必须在其构造的 runtime 上显式调用 `setLocale('zh')`；套件级的 `usePinnedBrowserLanguages('zh-CN')` 仅在同时声明了 `@vitest-environment jsdom` 的文件中生效，因为没有 `window` 时探测路径根本不会读取 `navigator`。此前有七个 `*.client.spec.ts` 文件带着这样一条失效的固定语句，实际依赖的是旧的 `zh` 回落值。
-- 探测的代价是每次服务构造遍历一次数组，且不会隐式写入 settings；插件激活后，显式 Host 偏好可能引发一次实时收敛。

 Locale plugin: LocaleRuntime — the preference stored as `locale.preference` in `$DSH_HOME/settings.yaml`; when that explicit Host value is absent, a fresh browser starts provisionally in the first registered language `navigator` asks for (full-tag then primary-subtag matching, with `en` when none match). The Host read runs after plugin activation so an unavailable settings service cannot block the page; its result replaces the provisional browser value live. A saved external locale waits for its definition to register rather than becoming active while unavailable. The Client keeps Host settings persistence disabled on non-loopback pages, so their locale selection remains process-local even though Connection authenticates every API method. `locale/change` fires on switches, and the plugin points `<html lang>` at the external language id or the built-in language's document tag on activation and on every switch. Product-authored Client UI text must enter through these typed dictionaries or an already-localized primitive prop; `verify-client-ui-i18n` enforces that source ownership ([decision](../../../.agents/notes/implemented/architecture/2026-08-23-locale-owned-client-ui-copy.md)). The [Host-backed preferences decision](../../../.agents/notes/implemented/bug-fix/2026-08-06-host-backed-web-preferences.md) owns the persistence boundary.
 
-The package ships only `zh` and `en`. External client plugins add a selectable language with `ctx.effect(() => ctx.locale.addLanguage({ id, label, fallback }))` and add its dictionaries through the existing `register(ns, locale, dict)` form; unloading the definition removes it from the selector and returns an active selection to the available browser/default locale. An external id is a non-empty ASCII BCP 47-style tag used for persistence, dictionary lookup, browser matching, and `<html lang>`. Its fallback must already be registered, and the resulting chain must terminate at `en`; unknown targets, duplicate ids, and cycles fail at registration. For each key, lookup walks the chain in the requested namespace, repeats it in `common`, then displays the key. The typed `register(ns, { zh, en })` form remains checked against `LocaleNamespaceMap` and requires both built-in dictionaries. LocaleRuntime implements the slot system's `LocaleFace` and installs itself through `ctx.slots.installLocale`, backing the framework-injected `t` standard seat (`Translate`/`TranslateNS` are ui-slots types; import them from there — this package only re-exports them for dictionary owners).

+# Agent Note: Adaptive and drag-resizable conversation content width
+
+Status: implemented
+
+English | [中文](2026-08-18-conversation-adaptive-content-width.zh.md)
+
+## Problem
+
+The conversation column's shared width axis (`--dsh-chat-content-width`) was the fixed figma constant 748px. On wide monitors (a 4000px display leaves a ~3500px column) the transcript occupied under a quarter of the column with dead margins on both sides. Every derived surface — the input card (W + 32px), dock cards, takeover panels, StatsLine, the back-to-bottom padding formula — rides this one variable, so any change had to keep the whole column's alignment relations intact. Alongside the adaptive default, users asked for direct control: hover the transcript's side margins to get a col-resize cursor and drag either edge, with both edges moving symmetrically.
+
+## Decision
+
+**The axis becomes a user override over an adaptive clamp.** `ConversationRoot.module.css` declares `--dsh-chat-content-width: var(--dsh-chat-user-width, clamp(680px, calc(var(--dsh-conversation-column-width, 0px) * 0.64), 920px))`. The floor is 680px — one step under the figma 748px, after full-width reading felt wide on every screen — wider columns take 64% of the column, and 920px caps line length for readability (~113 characters at the base font). A dragged preference replaces the adaptive term wholesale.
+
+**The column width is published by a ResizeObserver, not container queries.** The component publishes the root's `offsetWidth` as `--dsh-conversation-column-width` in px (the same callback-ref pattern as the existing composer seat height observer). `container-type: inline-size` was rejected: the conversation subtree contains portal-free `position: fixed` descendants (Tooltip, Menu, JsonTree copy anchors) whose viewport anchoring a size container would capture — the same class of trap the `.composerHero` comment records for transforms. A bare `%` in the variable was rejected because custom-property percentages resolve per consumer against different containing blocks, breaking the input-card = W + 32px invariant; `vw` was rejected because the column is not the viewport (sidebar fold changes the column only).
+
+**Drag handles are 40px strips beside the transcript, symmetric by construction.** Each strip's inner edge sits 24px outside the content column and extends 40px outward, with the outer edge clamped to keep a 24px safe zone from the column edges (24 + 40 + 24 = the 88px-per-side budget below); when the margin cannot fit inset + strip + safe zone the computed width goes negative and the strip resolves to zero. Both handles write the one centered width — outward travel widens by 2× the pointer distance — reusing AppFrame's DragHandle capture model (pointer capture + rAF throttle + drag-start snapshot); only a gesture with actual pointer travel commits to storage, so a bare press-and-release on a window-clamped width cannot overwrite the wider stored preference. The hover indicator is a 3px glow riding the pointer's Y (published as `--dsh-width-handle-pointer-y` on pointermove): a 24px solid core fading over 40px each side, in the scrollbar hover tint because border-token alphas disappear against the base fill. Handles render only in the active phase; views that elect a composer overlay (trajectory) hide them, and the header lifts above them (z-index 9) to stay clickable.
+
+**The preference persists in `localStorage` (`dsh.conversation.contentWidth`) and clamps without rewriting.** The displayed width re-clamps to `[640px, column − 176px]` when the column shrinks (88px per side keeps the handles fully placeable — a wider drag would push its own handles off the column), but the stored preference survives — widening the window restores it, the same rule AppFrame's sidebar drag follows. Double-clicking a handle clears the preference and returns to the adaptive clamp; the handle's `title` documents drag and double-click.
+
+**The user bubble cap follows the axis.** `min(525px, 82%)` becomes `min(calc(var(--dsh-chat-content-width, 748px) * 0.702), 82%)` (0.702 = 525/748, the figma bubble share of the figma column) in both `ui-conversation` MessageItem and the symmetric `ui-goal` command bubble, so bubbles scale with the column. The 748px fallback covers mounts outside the conversation column.
+
+## Alternatives considered
+
+**Raise the constant (748 → ~850).** Rejected: every mid-width window's line length grows too, hurting readability where most users live.
+
+**Wide-content bleed (code blocks and tool cards break out of the prose column).** Best reading ergonomics but touches MarkdownText and every tool card's layout; deferred as a possible second phase.
+
+**A settings-backed "wide mode" toggle.** Adds a persistent settings surface for what drag + double-click already covers; not needed.
+
+**A 12px handle strip beside the input card.** Shipped first and unusable in practice: on a wide screen the strip was a sliver in a thousand-plus pixels of margin, and the sticky input card overlapped it. Replaced by the 40px strip anchored to the glow line's position.
+
+## Consequences
+
+Ordinary windows read slightly narrower than the figma baseline (680px floor). Wide columns widen the transcript to at most 920px, and a drag can take it anywhere in `[640px, column − 176px]`, both without touching any derived surface: input card, dock cards, takeover panels, and the back-to-bottom formula follow the axis they already consumed. A known ~4px centering offset between the handle (column-centered) and the content box (centered after scrollbar-gutter reservation) stays well inside the 40px strip. The 680px / 64% / 920px numbers are one declaration in `ConversationRoot.module.css` mirrored by `resolveContentWidth` in the component; retuning them touches nothing else.

+# Agent Note：会话正文宽度自适应与拖拽调宽
+
+Status: implemented
+
+[English](2026-08-18-conversation-adaptive-content-width.md) | 中文
+
+## 问题
+
+会话列的共享宽度轴（`--dsh-chat-content-width`）是 figma 定值 748px。在宽显示器上（4000px 屏幕的会话列约 3500px）正文只占列宽不到四分之一，两侧是大片空白边距。所有派生表面——输入卡（W + 32px）、dock 卡片、takeover 面板、StatsLine、回底按钮的 padding 公式——都由这一个变量推导，任何改动都必须保持整列的对齐关系。在自适应默认值之外，用户还要求直接控制：hover 正文两侧边距出现 col-resize 光标，拖任一侧、两侧对称联动。
+
+## 决策
+
+**宽度轴变为"用户覆盖 + 自适应 clamp"。** `ConversationRoot.module.css` 声明 `--dsh-chat-content-width: var(--dsh-chat-user-width, clamp(680px, calc(var(--dsh-conversation-column-width, 0px) * 0.64), 920px))`。下限 680px——比 figma 的 748px 低一档，因为满宽阅读在各种屏幕上都显宽——更宽的列取列宽的 64%，920px 封顶保证行长可读性（基准字号下约 113 字符）。拖拽偏好存在时整体替换自适应项。
+
+**列宽由 ResizeObserver 发布，不用容器查询。** 组件把根节点的 `offsetWidth` 以 px 发布为 `--dsh-conversation-column-width`（与既有 composer seat 高度 observer 相同的 callback-ref 模式）。拒绝 `container-type: inline-size`：会话子树内有不经 portal 的 `position: fixed` 后代（Tooltip、Menu、JsonTree 复制锚点），尺寸容器会捕获它们的视口定位——与 `.composerHero` 注释记录的 transform 陷阱同类。拒绝变量里的裸 `%`：自定义属性百分比在各消费点按不同包含块解析，破坏输入卡 = W + 32px 不变量；拒绝 `vw`：列不等于视口（侧栏折叠只改列宽）。
+
+**拖拽手柄是正文两侧 40px 宽的条，对称是构造性的。** 每条内边缘位于内容列外 24px、向外延伸 40px，外边缘被钳制在距列缘至少 24px 的安全区（24 + 40 + 24 = 下文每侧 88px 的预算）；边距装不下"内偏移 + 热区 + 安全区"时计算宽度为负、热区解析为零。两个手柄写同一个居中宽度——向外拖按指针位移 2 倍变宽——复用 AppFrame DragHandle 的捕获模型（指针捕获 + rAF 节流 + 拖拽起点快照）；只有指针确实产生位移的手势才提交存储，因此在被窗口钳制的宽度上按下即松开不会用钳制后的显示值覆盖更宽的已存偏好。hover 提示是跟随指针 Y 的 3px 光带（pointermove 发布 `--dsh-width-handle-pointer-y`）：24px 实色核心、两侧各 40px 渐变，用滚动条 hover 色——border token 的透明度在底色上几乎不可见。手柄只在 active 阶段渲染；选举了 composer overlay 的视图（trajectory）隐藏手柄，header 提升到手柄之上（z-index 9）保持可点。
+
+**偏好持久化在 `localStorage`（`dsh.conversation.contentWidth`），钳制不改写。** 列收窄时显示宽度重新钳制到 `[640px, 列宽 − 176px]`（每侧预留 88px 保证手柄永远放得下），但存储的偏好保留——拉宽窗口自动恢复，与 AppFrame 侧栏拖拽同规则。双击手柄清除偏好、回到自适应 clamp；手柄的 `title` 说明拖拽与双击用法。
+
+**用户气泡上限跟随宽度轴。** `min(525px, 82%)` 改为 `min(calc(var(--dsh-chat-content-width, 748px) * 0.702), 82%)`（0.702 = 525/748，即 figma 气泡占 figma 列宽的比例），`ui-conversation` MessageItem 与对称的 `ui-goal` 命令气泡同步，气泡随列缩放。748px 缺省值覆盖会话列之外的挂载。
+
+## 备选方案
+
+**调大常量（748 → 约 850）。** 拒绝：所有中等宽度窗口的行长一起变长，伤及多数用户的可读性。
+
+**宽内容出血（代码块、工具卡片突破散文列）。** 阅读工效最佳但涉及 MarkdownText 和所有工具卡片布局；作为可能的二期推迟。
+
+**settings 支持的"宽屏模式"开关。** 为拖拽 + 双击已覆盖的能力增加持久设置面；不需要。
+
+**输入卡旁 12px 手柄条。** 首版实现，实践中不可用：宽屏上千余像素的边距里只有一条细缝，且 sticky 输入卡遮挡它。改为锚定在光带位置的 40px 条。
+
+## 影响
+
+普通窗口的阅读宽度比 figma 基线略窄（下限 680px）。宽列正文最多放宽到 920px，拖拽可取 `[640px, 列宽 − 176px]` 内任意值，两者都不触碰任何派生表面：输入卡、dock 卡片、takeover 面板和回底公式沿用它们本就消费的宽度轴。手柄（按列居中）与内容盒（按滚动条预留后居中）之间约 4px 的已知偏差完全落在 40px 热区内。680px / 64% / 920px 三个数值在 `ConversationRoot.module.css` 一处声明、由组件内 `resolveContentWidth` 镜像；重调它们不影响其他代码。

+# Agent Note: Settings-backed conversation content font size
+
+Status: implemented
+
+English | [中文](2026-08-18-settings-font-size-control.zh.md)
+
+## Problem
+
+The conversation's body text size was fixed (14px after the 0.875 markdown-ladder rescale). Users asked for a Settings control: a "字号大小" row under General → Appearance with a stepper, range 12–17, default 14, that resizes the transcript body text and the composer input text together.
+
+## Decision
+
+**The theme plugin owns the setting.** `ThemeSettingsSchema` gains `fontSize` (`z.number().step(1).min(12).max(17).default(14)`) beside `preference` in the existing `ui-theme` namespace — one durable section, one settings scope, one adoption path. `ThemeRuntime` carries `fontSize` in `ThemeSnapshot`, exposes `setFontSize(px)` (integer-and-range validated, throws a teaching error), and republishes on `theme/change`. The same plugin registers the FontSizeRow into `settings.general.item` at order 11, directly under the Appearance cubes (order 10).
+
+**Presentation rides the existing snapshot pipeline.** The service never touches the DOM: ui-layout's `ThemePresenter` writes `--dsh-content-font-size` on `body` from each snapshot (and retracts it on dispose), and the Host boot script embeds the durable value in the index response so first paint uses the chosen size — the same pre-plugin path the dark-mode attribute takes, avoiding a font-size flash.
+
+**One CSS delta variable moves the ladder.** `gradient-shadow-text.css` derives `--dsh-content-font-delta: calc(var(--dsh-content-font-size, 14px) - 14px)` and shifts the markdown h1–h4 and base variants (size and line height) by that same px increment, preserving the heading hierarchy and each variant's leading. Table, small, and code variants stay fixed: they are dense secondary text whose 12–13px defaults would collide with the base size when stepped down. Consumers outside the token ladder — the assistant narration root, the user bubble, and the composer card (whose textarea/mirror/backdrop stack inherits font metrics from the card by design) — read `var(--dsh-content-font-size, 14px)` and `calc(<default line-height> + var(--dsh-content-font-delta, 0px))` directly. The 14px fallbacks keep every surface pixel-identical when the variable is absent (tests, storybook-like mounts, remote compositions before adoption).
+
+**The stepper is a pill, not a menu.** The row reuses the selector-pill geometry (h36 r18 module fill) with the value centered in the pill, the up/down arrow column revealed on hover/focus-within and absolutely anchored to the pill's right edge (so revealing never moves the value), and a `px` unit label after the pill. Arrows disable at the bounds; the display follows the store mirror, never the click echo — the same store/face pattern as the Appearance row.
+
+## Alternatives considered
+
+**A separate settings namespace or plugin.** Rejected: the font size is an appearance preference with the same persistence, adoption, and remote-browser semantics as the theme preference; a second namespace duplicates the scope machinery for one integer.
+
+**Scaling via a multiplier (`em`/percentage) instead of a px delta.** Rejected: multiplying spreads the 12–17px range disproportionately across the ladder (21px h1 would swing ~18–25.5px) and produces fractional line heights; the fixed px shift keeps every step integer and the hierarchy's px gaps intact.
+
+**Scaling every font token (tables, code, small).** Rejected: those variants are secondary/dense by design; at −2 the small ladder would hit 10px and code 9px, below legibility.
+
+## Consequences
+
+The 0.875 markdown-ladder rescale (body 16 → 14) ships with this change as the new default rendering; at delta 0 every axis consumer is pixel-identical to that rescaled baseline, and surfaces without the variable fall back to the same 14px. A changed size persists in `$DSH_HOME/settings.yaml`, survives reloads without flashing (the boot script writes the durable value pre-hydration and `ThemeRuntime` seeds its initial snapshot from it), applies live across transcript and composer, and remote browsers keep the process-local-selection rule the theme preference already has. `setFontSize` joins the model-visible cordis client API catalog beside `setTheme`.

+# Agent Note：Settings 支撑的会话正文字号
+
+状态：已实现
+
+[English](2026-08-18-settings-font-size-control.md) | 中文
+
+## 问题
+
+会话正文字号是固定的（markdown 阶梯按 0.875 重缩放后为 14px）。用户需要一个设置项：在 General → Appearance 下加一行「字号大小」，用步进器交互，范围 12–17，默认 14，同时调整转录正文与 composer 输入框的文字大小。
+
+## 决策
+
+**主题插件拥有该设置。**`ThemeSettingsSchema` 在既有 `ui-theme` namespace 的 `preference` 旁新增 `fontSize`（`z.number().step(1).min(12).max(17).default(14)`）——一个持久化 section、一个 settings scope、一条采纳路径。`ThemeRuntime` 在 `ThemeSnapshot` 中携带 `fontSize`，暴露 `setFontSize(px)`（校验整数与范围，越界抛教学式错误），并通过 `theme/change` 重新发布。同一插件把 FontSizeRow 注册进 `settings.general.item`，order 11，紧挨外观方块（order 10）之下。
+
+**呈现走既有快照管线。**服务绝不接触 DOM：ui-layout 的 `ThemePresenter` 依据每份快照在 `body` 上写 `--dsh-content-font-size`（dispose 时收回），Host 引导脚本把持久化值嵌入 index 响应，让首帧就使用所选字号——与暗色属性同一条插件前路径，避免字号闪变。
+
+**一个 CSS 增量变量平移阶梯。**`gradient-shadow-text.css` 派生 `--dsh-content-font-delta: calc(var(--dsh-content-font-size, 14px) - 14px)`，把 markdown h1–h4 与 base 各变体（字号与行高）按同一像素增量平移，保持标题层级与各变体的行距。表格、small 与 code 变体保持固定：它们是密集次级文本，其 12–13px 默认值在字号下调时会与正文相撞。token 阶梯之外的消费方——助手正文根节点、用户气泡、composer 卡片（其 textarea/mirror/backdrop 三层按设计从卡片继承字体度量）——直接读取 `var(--dsh-content-font-size, 14px)` 与 `calc(<默认行高> + var(--dsh-content-font-delta, 0px))`。14px 回退让变量缺席时（测试、独立挂载、采纳前的远程组合）所有表面逐像素不变。
+
+**步进器是药丸控件，不是菜单。**该行复用选择器药丸几何（h36 r18 模块填充），数值在药丸内居中，上下箭头列在 hover/focus-within 时显示并绝对定位在药丸右缘（显示时数值不移动），药丸后带 `px` 单位标签。到达边界时对应箭头禁用；显示跟随 store 镜像，绝不跟随点击回声——与外观行相同的 store/face 模式。
+
+## 已考虑的替代方案
+
+**独立 settings namespace 或独立插件。**否决：字号与主题偏好具有相同的持久化、采纳与远程浏览器语义，属外观偏好；为一个整数复制一套 scope 机制不值得。
+
+**用倍率（`em`／百分比）而非像素增量缩放。**否决：乘法会让 12–17px 的范围在阶梯上不成比例地放大（21px 的 h1 会摆动到约 18–25.5px），并产生小数行高；固定像素平移让每一档都是整数，层级间的像素差保持不变。
+
+**缩放全部字体 token（表格、code、small）。**否决：这些变体按设计就是次级／密集文本；−2 档时 small 阶梯会降到 10px、code 降到 9px，低于可读下限。
+
+## 后果
+
+0.875 的 markdown 阶梯重缩放（正文 16 → 14）作为新的默认渲染随本变更一同交付；增量为 0 时所有轴消费方与该重缩放基线逐像素一致，无变量的表面回退到同样的 14px。修改后的字号持久化在 `$DSH_HOME/settings.yaml`，重载不闪变（引导脚本在 hydration 前写入持久化值，`ThemeRuntime` 以它为初始快照种子），在转录与 composer 上实时生效；远程浏览器沿用主题偏好既有的进程内选择规则。`setFontSize` 与 `setTheme` 一同进入模型可见的 cordis 客户端 API 目录。

Measuring after palette and token application keeps the rendered background as the single color authority; disposing the presenter removes its metadata node with its other global writes.
 
 AppFrame always mounts the conversation and details columns; a connected Session renders through `SessionProvider`. It also projects the selected Session title over the build-configured product title or the localized `common.brand.localBuild` fallback, so locale revisions update document metadata with the rest of the root entry. The transient layout store starts the sidebar at its default width and details closed, and it never reads or writes `localStorage`. Hero and other unselected states also derive a zero rendered details width without changing that stored preference. AppFrame retains the last non-blank Session id across those states: the first Session remains closed, an explicit details action opens the contract default width, returning to the same Session restores its unchanged width, and selecting a different Session closes details before paint. The conversation owner share is empty, while the sidebar owner share contains only `collapsed` and `width`; registrants obtain business data from standard hooks and actions from their own inject faces.

 AppFrame 始终挂载会话栏和详情栏；已连接 Session 通过 `SessionProvider` 渲染。它还会把选中 Session 的标题投影到 build 配置的产品标题或已本地化的 `common.brand.localBuild` 回退之上，因此 locale revision 会与 root entry 的其余内容一起更新文档元数据。布局 store 是瞬时状态，侧边栏以默认宽度启动，详情栏则保持关闭，且该 store 从不读写 `localStorage`。hero 和其他未选中状态也会将详情栏的渲染宽度派生为零，但不会改变存储的宽度偏好。AppFrame 会跨越这些状态保留最后一个非 blank 会话 id：首个会话保持关闭；显式打开详情栏的操作会使用约定默认宽度；返回同一会话时恢复其未改变的宽度；选择不同会话时，详情栏会在绘制前关闭。会话 owner share 为空，侧边栏 owner share 只包含 `collapsed` 和 `width`；注册方通过标准钩子获取业务数据，并从各自的 inject 接口获取操作。

+Theme plugin: ThemeRuntime over the --dsw-* token base stylesheets (static scale + alias semantic layers). The service owns the live theme preference (`light`/`dark`/`system`) and the conversation content font size (`fontSize`, integer px 12–17, default 14), resolves `system` through `prefers-color-scheme`, and publishes immutable `ThemeSnapshot`s on the `theme/change` event; it never touches the DOM — ui-layout's presenter applies the resolved snapshot (`html { color-scheme }`, `body[data-ds-dark-theme]`, `--dsh-content-font-size` on body, and inline alias tokens). A loopback browser provides the service immediately with the defaults, then loads the `ui-theme` namespace in the background and writes each accepted selection through the Host settings API, whose local provider stores it in `$DSH_HOME/settings.yaml` by default; pushed settings changes and reconnects refetch it, rapid selections are serialized in gesture order with namespace revisions, and a rejected latest write reloads the durable value.

When the host composition includes an HTTP server, the host half injects a synchronous bootstrap immediately after the opening `<body>` tag. Each index response embeds the registered Host settings for `ui-theme` (preference and font size), or the schema defaults when no settings provider is present; the browser resolves `system` from the OS scheme, then sets `color-scheme`, `body[data-ds-dark-theme]`, and `--dsh-content-font-size` before the shell loading page renders. Compositions without an HTTP server remain unaffected, and ThemeRuntime and ui-layout remain authoritative for client state and subsequent DOM updates after the plugin tree activates.
 
-When the host composition includes an HTTP server, the host half injects a synchronous bootstrap immediately after the opening `<body>` tag. Each index response embeds the registered Host setting for `ui-theme.preference`, or `system` when no settings provider is present; the browser resolves `system` from the OS scheme, then sets `color-scheme` and `body[data-ds-dark-theme]` before the shell loading page renders. Compositions without an HTTP server remain unaffected, and ThemeRuntime and ui-layout remain authoritative for client state and subsequent DOM updates after the plugin tree activates.
+The plugin registers two rows into the settings General section: the Appearance preference cubes and the font-size stepper (12–17 px, centered value with hover-revealed up/down arrows, a px unit label after the pill). The font size drives `--dsh-content-font-size`; `gradient-shadow-text.css` derives `--dsh-content-font-delta` from it and shifts the markdown heading/base ladder by the same px increment, while table, small, and code variants stay fixed. Consumers outside the token ladder (the user bubble, the composer draft) read the same pair directly.
 
 `src/styles/` holds five sheets imported in order by ui-theme's dynamic client entry: `base.css`, `design-platform.css`, `scrollbar.css`, `gradient-shadow-text.css`, and `shiki.css`. The client bundle compiles and injects them as plugin-owned global styles, so unload and HMR remove them with ui-theme instead of leaving theme CSS in the static web shell. `scrollbar.css` is the sole consumer of the `--dsw-alias-scrollbar-*` tokens and must follow `design-platform.css`, which declares them.

+插件向设置 General 区块注册两行：外观偏好方块与字号步进器（12–17 px，数值居中、hover 时显示上下箭头，药丸后带 px 单位标签）。字号驱动 `--dsh-content-font-size`；`gradient-shadow-text.css` 由它派生 `--dsh-content-font-delta`，让 markdown 标题／正文阶梯按同一像素增量整体平移，而表格、small 与 code 变体保持固定。token 阶梯之外的消费方（用户气泡、composer 草稿）直接读取同一对变量。
 
 `src/styles/` 下有五张样式表，由 ui-theme 的动态客户端 entry 依次导入：`base.css`、`design-platform.css`、`scrollbar.css`、`gradient-shadow-text.css` 与 `shiki.css`。客户端 bundle 将其编译并注入为插件持有的全局样式，因此卸载与 HMR 会随 ui-theme 一同移除这些样式，而不会把主题 CSS 留在静态 Web 外壳中。`scrollbar.css` 是 `--dsw-alias-scrollbar-*` token 的唯一消费方，必须排在声明这些 token 的 `design-platform.css` 之后。

Subject: [PATCH 131/155] feat(ui): extend the content font-size axis to flow
 chrome

Adopt --dsh-content-font-size / --dsh-content-font-delta across the flow
rows around the transcript body: DisclosureRow header (row height, title,
leading box, and registered glyphs, with StateDot exempt), ToolRow and
bash-row summaries and file links, think text, compaction/context/retry/
error rows, message clock and icon actions, the workflow-run panel, and
the workspace browser. Update the font-size Agent Note and add CSS-text
specs for the new adoptions.

 **Presentation rides the existing snapshot pipeline.** The service never touches the DOM: ui-layout's `ThemePresenter` writes `--dsh-content-font-size` on `body` from each snapshot (and retracts it on dispose), and the Host boot script embeds the durable value in the index response so first paint uses the chosen size — the same pre-plugin path the dark-mode attribute takes, avoiding a font-size flash.
 
-**One CSS delta variable moves the ladder.** `gradient-shadow-text.css` derives `--dsh-content-font-delta: calc(var(--dsh-content-font-size, 14px) - 14px)` and shifts the markdown h1–h4 and base variants (size and line height) by that same px increment, preserving the heading hierarchy and each variant's leading. Table, small, and code variants stay fixed: they are dense secondary text whose 12–13px defaults would collide with the base size when stepped down. Consumers outside the token ladder — the assistant narration root, the user bubble, and the composer card (whose textarea/mirror/backdrop stack inherits font metrics from the card by design) — read `var(--dsh-content-font-size, 14px)` and `calc(<default line-height> + var(--dsh-content-font-delta, 0px))` directly. The 14px fallbacks keep every surface pixel-identical when the variable is absent (tests, storybook-like mounts, remote compositions before adoption).

Table, small, and code variants stay fixed — as does the interrupted-turn `.stopped` tag (11px): they are dense secondary text whose defaults would fall below legibility when stepped down. Consumers outside the token ladder read `var(--dsh-content-font-size, 14px)` (or `calc(<own default> + var(--dsh-content-font-delta, 0px))` for smaller steps) and `calc(<default line-height> + var(--dsh-content-font-delta, 0px))` directly: the assistant narration root, the user bubble (reference summaries and their inline glyphs included), the composer card (whose textarea/mirror/backdrop stack inherits font metrics from the card by design), and the flow chrome around them — the shared DisclosureRow header (tool calls, think, commands; row height, title, and leading box all move) with its expanded bodies' `22px + delta` indent keeping content aligned under the shifted title start, ToolRow/bash-row summaries and file links, think text (12px keeping its 2px step under the body), compaction/context/retry/error rows, StatsLine, the chat hint and open-error strips, the workflow-run panel (run/phase headers and expanded member rows), the message clock and icon actions (slot-injected message-feedback actions match through the same variables), and the turn status line. Flow icons scale through each leading box's CSS edge (`svg` width/height overriding the glyph attributes); StateDot is exempt via its `data-state` attribute — a status mark, not text furniture. The 14px fallbacks keep every surface pixel-identical when the variable is absent (tests, storybook-like mounts, remote compositions before adoption).
 
 **The stepper is a pill, not a menu.** The row reuses the selector-pill geometry (h36 r18 module fill) with the value centered in the pill, the up/down arrow column revealed on hover/focus-within and absolutely anchored to the pill's right edge (so revealing never moves the value), and a `px` unit label after the pill. Arrows disable at the bounds; the display follows the store mirror, never the click echo — the same store/face pattern as the Appearance row.

Subject: [PATCH 132/155] polish(ui): trim the width handle and describe the
 font-size scope
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Drop the width handle's double-click reset and tooltip — the handle is now
drag-only and a stored preference is only replaced by another drag — and
add a tertiary description line under the Settings font-size title stating
the size only affects conversation content. Update both Agent Notes and
the settings dialog goldens.

 **Drag handles are 40px strips beside the transcript, symmetric by construction.** Each strip's inner edge sits 24px outside the content column and extends 40px outward, with the outer edge clamped to keep a 24px safe zone from the column edges (24 + 40 + 24 = the 88px-per-side budget below); when the margin cannot fit inset + strip + safe zone the computed width goes negative and the strip resolves to zero. Both handles write the one centered width — outward travel widens by 2× the pointer distance — reusing AppFrame's DragHandle capture model (pointer capture + rAF throttle + drag-start snapshot); only a gesture with actual pointer travel commits to storage, so a bare press-and-release on a window-clamped width cannot overwrite the wider stored preference. The hover indicator is a 3px glow riding the pointer's Y (published as `--dsh-width-handle-pointer-y` on pointermove): a 24px solid core fading over 40px each side, in the scrollbar hover tint because border-token alphas disappear against the base fill. Handles render only in the active phase; views that elect a composer overlay (trajectory) hide them, and the header lifts above them (z-index 9) to stay clickable.
 
-**The preference persists in `localStorage` (`dsh.conversation.contentWidth`) and clamps without rewriting.** The displayed width re-clamps to `[640px, column − 176px]` when the column shrinks (88px per side keeps the handles fully placeable — a wider drag would push its own handles off the column), but the stored preference survives — widening the window restores it, the same rule AppFrame's sidebar drag follows. Double-clicking a handle clears the preference and returns to the adaptive clamp; the handle's `title` documents drag and double-click.

 **One CSS delta variable moves the ladder.** `gradient-shadow-text.css` derives `--dsh-content-font-delta: calc(var(--dsh-content-font-size, 14px) - 14px)` and shifts the markdown h1–h4 and base variants (size and line height) by that same px increment, preserving the heading hierarchy and each variant's leading. Table, small, and code variants stay fixed — as does the interrupted-turn `.stopped` tag (11px): they are dense secondary text whose defaults would fall below legibility when stepped down. Consumers outside the token ladder read `var(--dsh-content-font-size, 14px)` (or `calc(<own default> + var(--dsh-content-font-delta, 0px))` for smaller steps) and `calc(<default line-height> + var(--dsh-content-font-delta, 0px))` directly: the assistant narration root, the user bubble (reference summaries and their inline glyphs included), the composer card (whose textarea/mirror/backdrop stack inherits font metrics from the card by design), and the flow chrome around them — the shared DisclosureRow header (tool calls, think, commands; row height, title, and leading box all move) with its expanded bodies' `22px + delta` indent keeping content aligned under the shifted title start, ToolRow/bash-row summaries and file links, think text (12px keeping its 2px step under the body), compaction/context/retry/error rows, StatsLine, the chat hint and open-error strips, the workflow-run panel (run/phase headers and expanded member rows), the message clock and icon actions (slot-injected message-feedback actions match through the same variables), and the turn status line. Flow icons scale through each leading box's CSS edge (`svg` width/height overriding the glyph attributes); StateDot is exempt via its `data-state` attribute — a status mark, not text furniture. The 14px fallbacks keep every surface pixel-identical when the variable is absent (tests, storybook-like mounts, remote compositions before adoption).

Subject: [PATCH 134/155] refactor(apiproxy): delete the goal unary domain

The goal domain has been served by GoalService's @Remote namespace since it
shipped; the API Proxy copy was a second implementation of the same six
mutations. Remove the goals contract, schemas, route rows, IApiClient stub,
host implementation, and the fixture's compatibility face, leaving
ctx.remote.goals as the only path.

The fixture's goal fold keeps its coverage through the Goal Remotes: its
lifecycle case moves out of the unary-dispatch test, which no longer has
goal rows to cover.

Subject: [PATCH 135/155] build(apiproxy): drop the now-unused goal dependency

Nothing under packages/host/apiproxy imports @deepseek-ai/dsh-goal after the
unary domain deletion, so the dependency and its project reference go too.

 - ACP, headless, SDK, and Web sessions publish cache rows for later consumers. The log-leading durability barrier may flush a covered prefix at the cache cadence and split otherwise coalesced physical JSONL runs; recorded profile snapshots re-pack the logical event stream so cache timing does not define fixture layout.
 - The per-record contract scopes failure: a malformed or stale-version document reads as an absent record at open, so one bad file never bricks the cache, and a checkpoint schema bump discards stale sessions per record instead of rejecting the whole domain.
-- No migration: the cache is derived data, never an authority. An obsolete cache (any earlier format) is never read — the first cold read refolds from the log and writes the current format.
+- The json backend bootstraps the per-record tree from the legacy whole-unit cache only when enumeration finds no new-layout document path. Any new document path, including an unreadable or stale file, suppresses the bootstrap for the whole unit; missing session rows refold from the log. The legacy file remains untouched.
 - The cache record is bound to the same log lifecycle as before: the stored `{createdAt, cwd}` identity guards against a recreated id.

 - `single` layout: the in-memory unit state is authoritative; every write primitive republishes the whole file via temp-write + fsync + atomic `rename()` replace. A unit file is always the complete current net state — legibility is this backend's reason to exist; scale is the SQLite backend's job.
 - A missing file (or unit directory, for `per-record`) opens as an empty unit and materializes on the first write. In `single` layout a foreign or unparsable file rejects with `malformed-medium`, and a stored version differing from the descriptor rejects with `version-mismatch` (no migration, pre-release stance). In `per-record` layout the contract is per record instead: a document that is malformed or stamped with another version reads as an absent record, so one bad or stale file never bricks the unit, and a version bump discards stale records rather than rejecting the whole unit.
+- An empty `per-record` tree bootstraps its declared-table records from a legacy `<unit>.json` whole-unit file and retains that file unchanged. Any new-layout document path in a declared table, or `global.json` for a declared global, suppresses the bootstrap for the whole unit even when the document is unreadable or stale; absent records remain absent instead of being filled from legacy state.
 - Write ordering across calls belongs to the caller (the domain layer's write chain); each single call is atomic and durable once resolved.

 - 缺失文件（`per-record` 时是缺失单元目录）会作为空单元打开，并在第一次写入时物化。`single` 布局下外来或无法解析的文件以 `malformed-medium` 拒绝；已存版本与描述符不同时以 `version-mismatch` 拒绝（预发布立场，不迁移）。`per-record` 布局的契约改为按记录：畸形或版本戳不符的文档读作"无此记录"，单个坏文件或过期文件不会拖垮整个单元，版本升级按记录丢弃过期行而不是拒绝整个单元。

For ordinary sessions, the `/model` popupSelect contribution (registered through `ctx.commandUi`) and the composer's named `conversation.input.model` seat both load the session's advisory directory through `session.models` and submit through `session.selectModel` via the same `ModelDirectory` instance.

+Model selection plugin, browser half: TWO entries over ONE per-session directory owned by `ModelDirectoryResolver` (`ctx.modelDirectories`). For ordinary sessions, the `/model` popupSelect contribution (registered through `ctx.commandUi`) and the composer's named `conversation.input.model` seat both load the session's advisory directory through `session.models` and submit through `session.selectModel` via the same `ModelDirectory` instance. The compact composer trigger opens a two-level Model/Effort menu: models stay provider-grouped, while the selected exact model supplies its adapter-owned effort names and default. The menu renders model and effort names only; catalog descriptions remain available to other consumers. `/model` applies the selected model's default effort, and the composer can then choose any advertised effort.
 
 The Host-reported provider/model/reasoning `ModelSelection` is the single selection fact, but it is echoed only when the exact provider/model pair remains in the advertised groups; an absent catalog row leaves the routable selection intact while the trigger prompts `Select model`, no stale row is synthesized, and no Effort row is shown until the user picks an advertised model. Directory loads and selections share a generation counter so an older response never overwrites a newer one; a connection reset drops every resident projection and repulls the Host-restored selection before display. Provider-local metadata failures list inline while usable groups stay selectable, and selection failures retain the prior selection and directory.

 Host 报告的 `ModelSelection` 是唯一的选择事实，其中包含提供方、模型与推理（reasoning）强度；但只有当该提供方／模型对仍在已公布分组中时才会回显。目录行缺席时，可路由的选择保持不变，但触发器会提示 `Select model`；系统不会合成陈旧行，且在用户选择已公布的模型之前不会显示 Effort 行。目录加载与选择共享一个代次计数器，旧响应不会覆盖新结果；连接重置会丢弃所有常驻目录投影，并在显示前重新拉取 Host 恢复的选择。各提供方的元数据获取失败会内联列出，同时可用分组仍可选择；选择失败会保留先前的选择和目录。

Subject: [PATCH 141/155] test(pwsh-local): accept graceful SIGTERM exit as
 service-disposal death

On Linux, pwsh may trap SIGTERM and exit cleanly when the subprocess service
is disposed, so the handle status is 'completed' rather than 'killed'. The
test already proved the process tree is gone via kill(pid,0); both statuses
satisfy the contract.

Subject: [PATCH 142/155] test: widen windows-hosted subprocess budgets in two
 web-stack specs

The self-hosted Windows coverage pool (16 shards x 12 workers on 192
threads) pushes real subprocess boots past their vitest deadlines: the
tool-pwsh Loader smoke reaches ~40s against a 30s process cap, and the
tool-ralph worker-thread cases exceed the 5s default. Give the pwsh
smoke a 90s process deadline (the subprocess keeps the assembled boot,
the vitest deadline stays at 120s), and give the two un-budgeted ralph
cases 30s each, matching the existing 20s quiescence case.

Subject: [PATCH 143/155] perf(ci): move the transform corpus out of coverage
 partitions

The full-corpus transform gate spawns one child that transforms and imports
every built bundle, so it runs for 8-25 minutes as a single case and
dominates one native Windows coverage partition, blowing its 900s budget
under load. Move it to the coverage-exempt heavy gate, which runs it with
its own worker budget instead of competing with the instrumented
partitions. The package's src is threshold-excluded in vitest.config.ts, so
the exemption carries no coverage; the exempt-heavy roster note records the
entry.

 - **One product onboarding path.** The root README owns the recommended package-run path, the source-run alternative, and compact `dsh plugin --profile` usage. The published user guide starts with tasks inside the running Web UI, then links to distinct tutorials or reference owners for other interfaces, plugin development, and advanced configuration instead of repeating Web startup.
 - **A narrow, hard budget gate.** [scripts/verify-doc-budgets.ts](../../../../scripts/verify-doc-budgets.ts) joins `doc-sync`: every doc listed in [scripts/doc-budgets.manifest.json](../../../../scripts/doc-budgets.manifest.json) must stay under its word ceiling (`wc -w` semantics, whole file), and a budgeted file that is missing fails the gate so a rename cannot silently orphan its budget. Scope is deliberately only the accretion-prone standing docs — the root and subtree `AGENTS.md` files, `architecture.md`, `packages/README.md`, and the standing policy docs they evict content into (`docs/testing.md`, `docs/defensive-patterns.md`). Reference docs, Agent Notes, and package READMEs are unbudgeted: length is legitimate there when every row is a fact, and review plus the slop checklist govern them.
 - **Ceilings are an enforcement frontier that ratchets.** A doc at or below its target keeps at least 5% headroom as its ceiling ratchets down; a doc above target keeps a frozen ceiling that prevents growth until it reaches the target (root `AGENTS.md` ≤ 1,600 words; `architecture.md` ≤ 1,800; subtree `AGENTS.md` ≤ 600 except `packages/AGENTS.md` ≤ 650 and `docs/AGENTS.md` ≤ 1,250; `packages/README.md` ≤ 600). When the gate goes red, relocate or condense; raise a ceiling only with explicit PR justification.

 ## Decision
 
-The root README preserves its existing structure, order, and wording wherever the underlying fact remains correct. A refresh changes only stale claims and adds material needed to represent shipped surfaces; it does not use repository growth as a reason to reframe the whole page.
+The root README is a compact product and contributor entry point. It states the product identity and plugin architecture, links the documentation site, marks the developer-preview and safety status, and then gives the supported npm and source launch paths.
 
-A note before installation thanks internal testers, states that features and experience remain unfinished, and asks for direct reports of failures, confusion, and friction through the WeCom group. The existing development-stage statement identifies DeepSeek Harness as being in internal testing.
+Both launch paths start the Web UI through the `dsh` profile entry point. The source path builds the checkout before it runs `pnpm dsh web`. Detailed ACP, TUI, SDK, capability, and package guidance stays in the user guide, architecture documentation, and package map instead of being repeated on the landing page.
 
-The user-surface section adds the ACP automation server and Python/JSON-RPC SDK beside the existing Web, TUI, and headless entries. The installed TUI remains the single `dsh` command; the Web instructions build the active checkout before running `dsh web`, and custom or reused checkout paths stay explicit. These launch paths must remain executable through a real PTY and a production build/HTTP smoke, respectively. The capability paragraph keeps its compact inventory style while adding the shipped PTY, LSP, web, goal, planning, task, sandbox, approval, settings, credentials, session-query, and telemetry families and stating that compositions select subsets. One adjacent bullet records the authoritative-session-log rule because persistence, replay, queries, telemetry, and interfaces depend on it.

-Detailed package and service inventories remain at their owning documentation. The English and Chinese README sides share the same technical structure, while their community sections continue to point to the primary channel for each language audience. The documentation website keeps a separate [quick-start entry route](../../../../docs/user/index.md) instead of presenting another product landing page.

 ## 决策
 
-只要背后的事实仍然正确，根 README 就保留既有结构、顺序和措辞。刷新时只修正陈旧声明，并补充呈现已交付内容所需的信息；不会因为仓库规模增长就重构整篇叙事。
+根 README 是简短的产品和贡献者入口。它说明产品定位与插件架构，链接文档站，标明开发者预览与安全状态，然后给出受支持的 npm 和源码启动路径。
 
-安装说明之前的一则文字感谢内测用户，说明功能和体验仍待完善，并邀请大家通过企业微信群直接反馈失败、困惑和不顺手之处。既有的开发阶段声明明确说明 DeepSeek Harness 处于内测阶段。
+两条启动路径都通过 `dsh` profile 入口启动 Web UI。源码路径先构建当前检出，再运行 `pnpm dsh web`。ACP、TUI、SDK、能力和包的详细说明由用户指南、架构文档与包索引维护，不在入口页重复。
 
-用户入口章节在已有的 Web、TUI 和 Headless 入口旁补充 ACP（Agent Client Protocol）自动化服务器和 Python/JSON-RPC SDK。安装后的 TUI 仍只需执行一条 `dsh` 命令；Web 说明要求先构建当前检出，再运行 `dsh web`，并明确处理自定义或复用的检出路径。这两条启动路径必须分别能在真实 PTY 与生产构建／HTTP 冒烟中原样执行。能力段落沿用简洁清单的写法，补充已经交付的 PTY、LSP、Web、目标、规划、任务、沙箱、审批、设置、凭据、会话查询和遥测等能力类别，并说明不同组合只选用其中一部分。相邻的一条列表项说明权威会话日志规则，因为持久化、回放、查询、遥测和各类接口都依赖它。
-
-包与服务的完整清单仍由各自的归属文档维护。中英文 README 采用相同的技术结构，但社区章节仍分别指向各自语言受众的主要交流渠道。文档网站保留独立的[快速开始入口路由](../../../../docs/user/index.zh.md)，不另行呈现产品首页。

 The native job is deliberately absent from `all-checks-passed.needs` and does not use `continue-on-error`: the aggregate neither waits for it nor changes conclusion because of it, while the job retains its own unmasked result. Workspace build, production-site, and 100%-per-file coverage failures make the native job fail. Static, documentation, package, built-artifact, lint, and snapshot inventories run in the same job as observational gates: their failures remain visible without changing the native aggregate result because Linux owns their blocking verdict.
 
-The 16-core lane admits four concurrent outer gates. Workspace build and production-site validation start immediately. Instrumented and exempt-heavy coverage both wait for the complete build: the instrumented corpus includes packer assertions over built `lib/` output, while the exempt gate's temporary Oxlint contract probes must not race source compilation. Every observational gate waits for both coverage gates to settle, regardless of outcome, before entering an available slot; its own `needs` edges still require their predecessors to pass. This also keeps later static gates that create temporary contract files from racing either coverage scan. [In-job partitioned coverage](2026-08-18-in-job-partitioned-coverage.md) uses four single-worker shards, while the exempt-heavy gate receives two workers from `DSH_COVERAGE_MAX_WORKERS=6`, for about six active coverage execution units after build. `publint` is capped at eight workers when the observational inventory starts. Every Vitest project uses forked workers because Node 24's CJS lexer fatal reproduced in shared worker threads on Windows and POSIX. Both coverage gates set Vitest's default per-test and polling budgets to 30 seconds because unrelated process, Git, SQLite, watcher, grammar, and static-gate fixtures can exceed 15 seconds only under the complete lane's concurrent Windows instrumentation. The SQLite busy-journal pacing fixture injects two busy results followed by success under the normal busy budget and observes each inter-attempt delay, keeping schema-setup scheduling outside its timing assertion. The script-only translation-pairing merge suite runs in the exempt-heavy gate because it imports only `scripts/` sources and child processes; V8 instrumentation contributes no threshold coverage there but magnifies Git-process latency. Lefthook concurrency fixtures retain their outcomes with 30-second case budgets and a 10-second process-ready probe, while the installer allows five seconds for a preempted lock owner to publish its record after exclusive creation. Directory-picker composition gives its debounced config write an explicit 15-second poll budget; workspace-context composition fixtures use a test-owned signal without an unrelated one-second deadline. These lane-scoped budgets preserve asserted outcomes, while the 120-minute job deadline still bounds a stuck run. The LSP sources and the ACL-sandbox sources remain in the Windows denominator: stub-based failure-path suites carry every in-process ACL-sandbox file to 100%, and only the runner entry stays excluded — it executes exclusively as a spawned child outside the instrumented run, its behavior pinned end-to-end by the runner suite.

 The 16-core allocation is the measured capacity point for this inventory. Six-worker coverage trials produced complete passes in 6 minutes 27 seconds and 7 minutes 50 seconds, while exact-head trials with four, three, and two concurrent workers inside one instrumented Vitest process exposed unreliable fixtures and worker exits. Separate single-worker child processes retain process isolation. Historical sixteen-shard samples reduced instrumented coverage to 112.66–122.01 seconds. Under the current post-build graph, sixteen instrumented shards plus two exempt workers would schedule eighteen coverage execution units on a 16-core runner before any production-site tail or system overhead; four shards plus two exempt workers schedule six. Four deliberately trades some single-job latency for lower process-creation pressure under high self-hosted concurrency. A 32-core comparison reduced aggregate gate time by only 1.47 seconds and still triggered the CJS-lexer fatal inside a fork worker, so additional cores did not provide a reliable wall-clock improvement.

+# Agent Note: Audience-first documentation quality criteria
+
+Status: proposed
+
+English | [中文](2026-08-20-audience-first-documentation-quality.zh.md)
+
+## Problem
+
+The documentation system has strong placement, freshness, linking, bilingual, and source-equivalence checks, but it does not define “brief, intuitive, and friendly” as reviewable outcomes for users, newcomers, developers, and agents. All `doc-sync` checks and translation pairs pass, while the following design problems remain. The first three findings are the design priorities; the capacity finding explains why adding more standing rules will not solve them.
+
+### Semantic correctness can pass without a current owner
+
+The gates prove structure and generated freshness, not that maintained prose still names the live mechanism. The former `dsh-doc-site-sync` skill told authors to reuse a nonexistent `en-docs` sidebar and to add sections to a removed `sectionOrder`; [website/docs.ts](../../../../website/docs.ts) owns `en-guide`, `en-develop`, `en-reference`, and `sections`. The implemented [product-first README decision](../../implemented/process/2026-07-22-product-first-root-readme.md) describes an internal-testing notice and ACP, Python, and JSON-RPC surface sections absent from the [root README](../../../../README.md), although implemented Agent Notes must track shipped facts.
+
+The budget policy has the same split. [docs/AGENTS.md](../../../../docs/AGENTS.md#wordcount-budgets) states a 1,800-word target and 5% headroom for `architecture.md`, but the [budget manifest](../../../../scripts/doc-budgets.manifest.json) allows 2,400 words while the file contains 1,313. The budget gate passes because it checks the manifest ceiling, not the target or ratchet rule. High-impact prose therefore needs a named source or a focused check that consumes the source; a second hand-written copy is not a freshness mechanism.
+
+### Reader success is implicit rather than testable
+
+The standard classifies pages as tutorials or references and asks authors to classify a tutorial reader privately. It does not require a reviewable statement of the reader’s starting state, desired outcome, shortest successful path, likely failure, or next useful page. A document can therefore satisfy tier placement, links, word limits, and Markdown structure without proving that its intended reader can complete the task.
+
+The public site makes the pressure visible. Each locale publishes 84 pages: 3 guide pages, 17 developer pages, and 63 reference pages. The 13 English files under `docs/user/` contain 7,540 words, while 47 subsystem pages contain 100,759 words. The short Web quick start is a good product entry, but no corpus-level criterion verifies that a first-time user, a plugin newcomer, and a maintainer each has one obvious path from entry to outcome and recovery.
+
+### Generated accuracy and retrieval quality are conflated
+
+The repository contains 19 fully generated English Markdown files with 49,611 words. Forty-four of 47 subsystem pages also contain generated Cordis regions; those regions contribute 34,622 of the subsystem tier’s 100,759 words. `config-catalog.md` has 14,807 words, `tool-catalog.md` has 10,599, and the largest mixed subsystem pages contain 5,600–7,781 words.
+
+These are legitimate exhaustive references, so a blanket word limit would delete value. Their generators prove completeness and freshness, but the standard has no separate retrieval criterion for an agent with a limited context window or a human looking for one answer. A generated reference needs a compact entry layer, stable grouping, direct anchors, and a split rule based on lookup cost; exhaustive detail can remain exhaustive behind that entry layer.
+
+### The standard has no room for its next rule
+
+The standing documentation file is 1,320 words against a 1,320-word ceiling and a stated 1,250-word target. Root `AGENTS.md` is 1,936 words against a 1,600-word target, `packages/AGENTS.md` is 672 against 650, and `packages/README.md` is 969 against 600. The frozen ceilings prevent further growth but do not create a place for audience and outcome criteria. Adding more standing prose would deepen the problem the standard is meant to prevent.
+
+### Baseline
+
+The audit excludes `vendor/`, frozen `.agents/notes/archived/`, recorded snapshots, and fixtures. It counts 1,042 English Markdown files and 986 Chinese counterparts in the maintained corpus, with 1,106,138 English words. Active Agent Notes account for 580 files and 637,850 words; Markdown under `packages/` accounts for 276 files and 225,630 words; `docs/` accounts for 112 files and 193,456 words. These quantities describe maintenance and retrieval pressure, not defects by themselves.
+
+The system’s strongest properties should remain: one fact owner by tier, canonical Markdown projected into the website without copies, complete bilingual pairing, generated catalogs that fail when source changes, type-equivalent declarations, compilable TypeScript examples, checked links and anchors, and package-local model-experience and limitation contracts. The proposal changes quality criteria and entry structure, not those guarantees.
+
+## Proposal
+
+Adopt one audience-first quality contract with five definitions:
+
+- **Brief** means the common path contains only the facts needed for its outcome. Exhaustive contracts remain available through a direct link or generated detail; brevity never means deleting required behavior, failures, ownership, or limitations.
+- **Intuitive** means the page establishes its reader’s starting state, introduces prerequisites before dependent concepts, offers one obvious next action, and uses the product or domain terms a reader will search for.
+- **Friendly** means a reader can recognize success, understand material risk before acting, recover from the likely failure, and reach the next relevant depth without first learning unrelated architecture.
+- **Accurate** means every durable claim has one owner and a verification path appropriate to its risk. Generated facts derive from source; hand-written workflow values link to or consume their owner instead of copying enums and paths.
+- **Agent-readable** means headings, anchors, terminology, ownership, and current-versus-proposed status are explicit enough to retrieve the needed section without loading an entire corpus or reconstructing review history.
+
+### Prototype rules
+
+The [dsh-doc skill](../../../skills/dsh-doc/SKILL.md) owns the first executable version of these rules. The SQLite README pair uses the shipped packed-row implementation as evidence rather than treating its prior prose as authority.
+
+- Every authored package README starts with searchable YAML. A Skill-style `description` and mechanically derived `kind` are required. Four kinds map one-to-one to four skill templates: `package-group` (group map), `package-reference` (plugin or service package), `package-library` (plain module entry), and `package-bundle` (`dsh.bundle.patch`). The counterpart path, hashes, and physical line alignment belong to the merge-safe sidecar and its gate, so README frontmatter contains no `i18n` block. The title or package manifest already owns the name, the document job expresses its audience, and tags remain absent until a governed taxonomy and search consumer proves value beyond full-text search.
+- Authored pages start with a three-to-five-sentence `Summary`, then a linked `Table of Contents`. Format-owned Agent Notes, postmortems, generated fragments, and machine files keep their required skeletons.
+- Each substantive section starts with a short orientation before subsections, tables, or code, and the page progresses from basic user use to advanced developer and maintainer detail.
+- English technical prose uses an ASD-STE100-inspired, non-certified clarity review: explicit actors and actions, stable terms, direct verbs, separated instructions and conditions, and preserved modality, exceptions, timing, and numbers. The 20-word instruction and 25-word description limits are review prompts. Precision overrides them.
+- Package contracts remain beside code. Cross-package material moves deliberately toward `docs/learn/overview/`, `docs/learn/cordis/`, `docs/learn/practices/`, `docs/user/`, `docs/developer/`, `docs/developer/discussion/`, `docs/scratch/`, and the parallel `docs/subsystems/` tier.
+- English and Chinese pages keep equal authority, matching structure, links, code, frontmatter layout, and exact physical line count.
+- Inline pair metadata is the target replacement for sidecars. The prototype may carry both until the verifier, merge driver, recovery flow, generated-region recorder, and archive checks consume a non-self-referential pair digest.
+- Repository-root internal links are the target authoring model. The prototype keeps renderer-valid relative links because leading `/` currently leaves the repository on GitHub, bypasses `verify-md-links`, and remains unprojected by the website.
+- `Further Exploration` is an optional newcomer route to three to seven adjacent pages.
+- Every authored page ends with `Dev Note`, the sole place for active rough context. It remains non-authoritative, links rather than duplicates task state, and is promoted or cleaned when work closes.
+- Independently searchable rules, practices, examples, and decisions use small files under descriptive folders when they have distinct owners or change cadence; tightly coupled obligations stay together.
+
+### Criteria by document job
+
+| Job | Primary outcome | Required entry information | Verification |
+|---|---|---|---|
+| Product quick start | Complete one representative task | Prerequisites, one launch path, first success, safety boundary, next step | Built or packaged smoke for the documented path plus link/site checks |
+| User task guide | Complete or recover one user task | Starting UI/API state, ordered actions, observable result, likely failure and recovery | Behavior test, screenshot review when visual state matters, or named manual owner |
+| Contributor tutorial | Reach a checked development state | Supported runtime, setup commands, expected result, narrow follow-up commands | Clean-checkout command smoke on a supported environment |
+| Architecture overview | Reconstruct the system from one page | Product composition, owners, dependency direction, extension points, links to detail | Source-backed package or graph checks plus focused human review |
+| Package or subsystem reference | Look up one contract without reading implementation | Scope, owned types or behavior, failures, lifecycle, limitations, related owners | Existing JSDoc, type-equivalence, generated-region, README, and link checks |
+| Generated reference | Locate one exact item and trust its completeness | Scope, generation owner, grouping/index, stable anchors, related conceptual guide | Deterministic `--check`, completeness fixture, site build, and retrieval-size report |
+| Agent instruction or skill | Apply one workflow without stale copied values | Scope, authority links, required decisions, exact commands only when owned here | Metadata/link checks and focused tests for copied machine values |
+| Proposed or implemented Agent Note | Understand a decision, trade-off, and state | Problem, proposal or decision, alternatives, acceptance or consequences | Existing lifecycle, format, pairing, and supersession checks; review owns semantic currency |
+
+The table belongs in one canonical quality reference. `docs/AGENTS.md` should retain only the short standing orders needed whenever documentation is edited and link to that reference. This creates budget headroom instead of placing another complete standard inside agent context.
+
+### Generated-reference entry and detail layers
+
+Every generated reference should expose a compact entry layer before exhaustive output: scope, intended lookup, grouping or index, direct links to conceptual guidance, and the generator/check command. Generators should report page words, entry count, heading count, and largest section. A page crosses a review threshold when one lookup requires scanning unrelated groups or when one page dominates agent context; the owner then splits it by a stable domain already present in source metadata rather than by an arbitrary word slice.
+
+The first prototype should use one large catalog and one mixed subsystem page. It should compare lookup steps, generated diff size, build time, route stability, and agent context needed for representative questions before any corpus-wide split. Existing anchors need aliases when routes move.
+
+### Enforcement slices
+
+1. Create and validate `dsh-doc`, then rewrite the `session-persistence-sqlite` README pair as a line-aligned, metadata-bearing prototype without changing runtime claims.
+2. Review the rendered prototype with newcomer, user, developer, and agent tasks; revise the skill before enforcing the format elsewhere.
+3. Add narrow metadata, section-order, line-alignment, link-resolution, and pairing fixtures. Keep sidecars until every merge and recovery consumer has replacement support.
+4. Extract accepted standing rules into one canonical quality reference, condense `docs/AGENTS.md` below its target, and organize one coherent `docs/` topic at a time with atomic link/navigation repair.
+5. Prototype generated-reference entry/detail separation on `config-catalog.md` and `docs/subsystems/core.md`; apply confirmed patterns elsewhere only after measured lookup cost falls without lost facts or route churn.
+
+This sequence keeps each change independently reviewable. The first three slices improve criteria and correctness without rewriting the corpus; the generated-doc prototype supplies evidence before a broader information-architecture change.
+
+Slices 1–3 have shipped in this form: `dsh-doc` is the consolidated standard (`dsh-doc-standards` and `dsh-doc-site-sync` are folded into it, and the site workflow carries the corrected sidebar values), the `session-persistence-sqlite` README pair is the reference example, and `pnpm run test:docs` enforces the metadata, pairing, and quick documentation checks. Slices 4–5 remain open.
+
+### Non-goals
+
+This proposal does not shorten exhaustive facts, merge audience tiers, publish internal decision records, restore an Agent Note index, split tightly coupled rules for file-count symmetry, or treat the audit as user research. It does not delete current pairing or link infrastructure before its replacement passes equivalent recovery and rendering checks.
+
+## Alternatives considered
+
+**Apply one word ceiling to every document.** Rejected because exhaustive reference rows, public contracts, and decision rationale can be long and correct. Entry-path length and lookup cost are the relevant constraints for those jobs.
+
+**Require one universal page template or audience frontmatter.** Rejected because it would add ceremony to generated pages, package references, and short instructions without proving reader success. The standard defines outcomes by document job, uses `kind` only where it selects a concrete package-document standard, and adds only fields that a focused check or reviewer consumes.
+
+**Use readability scores as the quality gate.** Rejected because formulas penalize exact technical terms and cannot detect wrong ownership, missing failure behavior, stale commands, or a broken reader journey.
+
+**Rewrite or split the full corpus immediately.** Rejected because the current system is mechanically healthy and many long references are appropriately exhaustive. A prototype should prove a retrieval improvement before route and translation churn spreads.
+
+**Keep the existing gates and rely on review for friendliness.** Rejected because the stale workflow values and budget-policy mismatch show that review alone does not preserve copied semantic claims, and the current gates do not ask whether a reader can complete a task.
+
+## Acceptance criteria
+
+- One canonical quality reference defines brief, intuitive, friendly, accurate, and agent-readable documentation by document job.
+- `.agents/skills/dsh-doc` validates and directly links its metadata, structure/hierarchy, and review/prototype references without duplicating their detailed rules in `SKILL.md`.
+- The SQLite README pair demonstrates searchable YAML, Summary, Table of Contents, user-to-developer progression, Further Exploration, final Dev Note, structural parity, and exact line-count equality while preserving verified package contracts.
+- `docs/AGENTS.md` links that reference, remains sufficient as standing instruction, and is below its target with at least 5% headroom.
+- The root user path, Web quick start, first-plugin tutorial, contributor setup, and architecture overview each name an observable outcome and a verification owner without duplicating implementation detail.
+- The budget manifest records both target and temporary ceiling, and its check reports or rejects a violated headroom/ratchet state.
+- The docs-site workflow contains no copied invalid sidebar name or section-owner claim, and a focused test prevents recurrence.
+- The sidecar remains the single consistency record because it preserves equal authority, last-confirmed-text recovery, automatic merge safety, generated-region recording, and archive sealing without creating owner-file conflicts.
+- An accepted repository-root link form renders correctly on GitHub and the documentation site and remains locally target/anchor checked before relative links are migrated.
+- One large standalone catalog and one mixed subsystem page demonstrate a compact entry layer and lower measured lookup cost while preserving exhaustive generated truth, stable links, bilingual pairing, and deterministic freshness.
+- `pnpm run doc-sync`, `pnpm run lint`, the focused new checks, and `git diff --check` pass.
+
+## Risks
+
+- Metadata can become boilerplate; the package README check therefore permits only fields with current retrieval, template-selection, or bilingual-consistency consumers.
+- Hard sentence limits can fragment explanations or separate a condition from its consequence. The controlled-English word counts remain review prompts, and exact contracts override them.
+- Exact line alignment can pressure translators into unnatural prose; review must protect meaning and may revise both sides together rather than weaken one.
+- Splitting generated references can increase routes and link maintenance; prototypes must preserve aliases and measure the trade-off.
+- A semantic check can become a repository-topology scanner that blocks legitimate changes; checks should cover high-risk copied values and representative journeys, while review owns prose meaning.
+- Package README quick-reference tables manually repeat selected configuration defaults; until a source-driven check owns them, reviewers must verify changed values against source and the generated config catalog and keep the tables selected rather than exhaustive.
+- Optimizing for short agent context can make human references fragmented; each split needs one stable conceptual owner and one obvious navigation path.
+- A permanent Dev Note can become a second queue or stale history dump; completion must promote durable truth and remove resolved chatter.
+- The audit uses repository structure, gates, and representative pages rather than user research. Before broad rollout, maintainers should validate the proposed reader outcomes with actual newcomer, user, developer, and agent tasks.

+# Agent Note: 以受众为先的文档质量标准
+
+Status: proposed
+
+[English](2026-08-20-audience-first-documentation-quality.md) | 中文
+
+## 问题
+
+文档系统拥有健全的放置、新鲜度、链接、双语和源等价性检查，却没有把「简短、直观、友好」定义成可供用户、新人、开发者和 agent（智能体）评审的结果。全部 `doc-sync`（文档同步门禁）检查和全部翻译配对均通过，但仍存在以下设计问题。前三项发现是设计重点；容量问题则解释了为什么增加更多常驻规则无法解决它们。
+
+### 语义正确性可以在没有现行归属者的情况下通过检查
+
+这些门禁证明结构和生成内容的新鲜度，却不能证明维护中的正文仍指向实际机制。以前的 `dsh-doc-site-sync` 技能曾要求作者复用并不存在的 `en-docs` 侧边栏，还要求把章节加入已经移除的 `sectionOrder`；[website/docs.ts](../../../../website/docs.ts)实际拥有 `en-guide`、`en-develop`、`en-reference` 和 `sections`。已实现的[产品优先 README 决策](../../implemented/process/2026-07-22-product-first-root-readme.zh.md)描述了内部测试说明，以及 ACP、Python 与 JSON-RPC 界面章节，但[根 README](../../../../README.zh.md)并无这些内容；与此同时，已实现 Agent Note 必须跟随已交付事实。
+
+预算策略也存在相同的分裂。[docs/AGENTS.md](../../../../docs/AGENTS.md#wordcount-budgets)为 `architecture.md` 规定 1,800 词目标和 5% 余量，但[预算 manifest（元数据清单）](../../../../scripts/doc-budgets.manifest.json)允许 2,400 词，而该文件实际包含 1,313 词。预算门禁之所以通过，是因为它只检查 manifest 上限，不检查目标或棘轮规则。因此，高影响正文需要一个具名真源或消费真源的聚焦检查；第二份手写副本不是新鲜度机制。
+
+### 读者成功与否是隐含判断，而不是可测试结果
+
+标准把页面分成教程和参考，并要求作者私下判断教程读者的起始水平。标准没有要求留下可供评审的读者起始状态、预期结果、最短成功路径、常见失败或下一篇有用页面。因此，一份文档可以满足层级放置、链接、词数限制和 Markdown 结构，却没有证明目标读者能完成任务。
+
+公共站点直观呈现了这种压力。每种语言发布 84 个页面：3 个指南页面、17 个开发页面和 63 个参考页面。`docs/user/` 下的 13 个英文文件共有 7,540 词，而 47 个子系统页面共有 100,759 词。简短的 Web 快速开始是良好的产品入口，但全语料没有标准来验证首次使用者、插件新人和维护者是否都能沿一条明确路径从入口走到结果与故障恢复。
+
+### 生成内容的准确性与检索质量混为一谈
+
+仓库包含 19 个完全生成的英文 Markdown 文件，共 49,611 词。47 个子系统页面中有 44 个也包含生成的 Cordis 区域；这些区域占子系统层级 100,759 词中的 34,622 词。`config-catalog.md` 有 14,807 词，`tool-catalog.md` 有 10,599 词，最大的混合子系统页面则有 5,600–7,781 词。
+
+这些内容是正当的穷尽式参考，因此统一词数限制反而会删除价值。生成器证明完整性和新鲜度，但标准没有为上下文窗口有限的 agent，或只寻找一个答案的人类读者另设检索标准。生成参考需要紧凑的入口层、稳定分组、直接锚点，以及根据查询成本触发的拆分规则；穷尽式细节可以在该入口层之后继续保持穷尽。
+
+### 标准没有容纳下一条规则的空间
+
+常驻文档标准有 1,320 词，等于 1,320 词上限，并超过声明的 1,250 词目标。根 `AGENTS.md` 有 1,936 词，目标为 1,600；`packages/AGENTS.md` 有 672 词，目标为 650；`packages/README.md` 有 969 词，目标为 600。冻结的上限能阻止进一步增长，却没有为受众和结果标准创造位置。继续增加常驻正文会加深该标准本应防止的问题。
+
+### 基线
+
+本次审计排除 `vendor/`、冻结的 `.agents/notes/archived/`、录制快照和 fixture（测试前置数据）。受维护语料包含 1,042 个英文 Markdown 文件和 986 个中文对侧文件，共 1,106,138 个英文词。活跃 Agent Note 占 580 个文件和 637,850 词；`packages/` 下的 Markdown 占 276 个文件和 225,630 词；`docs/` 占 112 个文件和 193,456 词。这些数量描述维护和检索压力，本身并不构成缺陷。
+
+系统最强的性质应予保留：按层级为每项事实指定一个归属者；把规范 Markdown 投影到站点而不创建副本；完整双语配对；源变更时快速失败的生成目录；源等价声明；可编译的 TypeScript 示例；受检查的链接与锚点；以及包局部的模型体验与限制约定。提案改变的是质量标准和入口结构，而不是这些保证。
+
+## 提案
+
+采用一套以受众为先的质量约定，并给出五项定义：
+
+- **简短**表示常用路径只包含达成结果所需的事实。穷尽式约定仍可通过直接链接或生成细节访问；简短绝不意味着删除必要行为、失败、所有权或限制。
+- **直观**表示页面会确定读者的起始状态，在依赖概念之前介绍前置知识，提供一个明确的下一步操作，并使用读者会搜索的产品或领域术语。
+- **友好**表示读者能识别成功，在操作前理解实质风险，从常见失败中恢复，并在无需先学习无关架构的情况下进入下一层相关细节。
+- **准确**表示每项持久事实都有一个归属者和与风险相称的验证路径。生成事实来自源；手写工作流值链接或消费其归属者，而不是复制枚举和路径。
+- **便于 agent 阅读**表示标题、锚点、术语、所有权以及当前与提议状态足够明确，无需加载整个语料或重建评审历史即可检索所需章节。
+
+### 原型规则
+
+[dsh-doc skill](../../../skills/dsh-doc/SKILL.md) 负责这些规则的首个可执行版本。SQLite README 对以已交付的分片行实现为证据，而不把其旧版正文当作权威。
+
+- 每个撰写型包 README 都以可搜索 YAML 开头。Skill 风格的 `description` 与按机制推导的 `kind` 为必填字段。四种 kind 与四个技能模板一一对应：`package-group`（组地图）、`package-reference`（插件或服务包）、`package-library`（纯模块入口）与 `package-bundle`（`dsh.bundle.patch`）。对照文件路径、哈希与物理行对齐由支持自动合并的 sidecar 及其门禁负责，因此 README frontmatter 不包含 `i18n` 块。名称已由标题或包 manifest 归属，受众已由文档职责表达；在受治理的标签分类与搜索消费方证明其价值超过全文检索之前，不加入标签。
+- 撰写型页面先写三至五句的 `Summary`，再写带链接的 `Table of Contents`。由格式约束的 Agent Note、事故复盘、生成片段和机器文件保留其必需骨架。
+- 每个实质章节在子章节、表格或代码之前先给出简短引导，页面则从基础用户用法逐步进入高级开发者与维护者细节。
+- 英文技术正文采用受 ASD-STE100 启发但不宣称认证的清晰度评审：明确行动者与动作，稳定使用术语，使用直接动词，拆分指令与条件，并完整保留情态、例外、时序与数值。指令 20 词和描述 25 词的限制仅作评审提示。准确性高于句长。
+- 包约定留在代码旁。跨包材料有计划地向 `docs/learn/overview/`、`docs/learn/cordis/`、`docs/learn/practices/`、`docs/user/`、`docs/developer/`、`docs/developer/discussion/`、`docs/scratch/` 和平行的 `docs/subsystems/` 层级迁移。
+- 英文和中文页面保持同等权威，并在结构、链接、代码、frontmatter 布局和精确物理行数上一一对应。
+- 内联配对元数据是伴随文件的目标替代方案。在验证器、合并驱动、恢复流程、生成区域记录器和归档检查消费非自引用配对摘要之前，原型可以同时保留两者。
+- 仓库根级内部链接是目标撰写模型。原型保留渲染器可用的相对链接，因为前导 `/` 当前会在 GitHub 上离开仓库、绕过 `verify-md-links`，并且不会由站点投影。
+- `Further Exploration` 是可选的新人路径，链接三至七个相邻页面。
+- 每个撰写型页面都以 `Dev Note` 结尾，作为活跃粗略上下文的唯一位置。它保持非权威状态，只链接而不复制任务状态，并在工作结束时完成提升或清理。
+- 可独立搜索的规则、实践、示例和决策在拥有不同归属者或变更节奏时，使用描述性目录下的小文件；紧密耦合的义务保留在一起。
+
+### 按文档职责划分的标准
+
+| 职责 | 主要结果 | 必需入口信息 | 验证 |
+|---|---|---|---|
+| 产品快速开始 | 完成一项有代表性的任务 | 前置条件、一个启动路径、首次成功、安全边界、下一步 | 文档路径的构建或打包冒烟测试，加链接和站点检查 |
+| 用户任务指南 | 完成一项用户任务或从中恢复 | 起始 UI／API 状态、有序操作、可观察结果、常见失败及恢复 | 行为测试；涉及视觉状态时评审截图；或指定人工归属者 |
+| 贡献者教程 | 进入通过检查的开发状态 | 支持的运行时、设置命令、预期结果、聚焦的后续命令 | 在受支持环境中对干净检出运行命令冒烟测试 |
+| 架构概览 | 从一个页面重建系统 | 产品组合、归属者、依赖方向、扩展点、细节链接 | 由源支持的包或图检查，加聚焦人工评审 |
+| 包或子系统参考 | 无需阅读实现即可查到一项约定 | 范围、归属的类型或行为、失败、生命周期、限制、相关归属者 | 既有 JSDoc、类型等价、生成区域、README 和链接检查 |
+| 生成参考 | 找到一个精确条目并信任其完整性 | 范围、生成归属者、分组或索引、稳定锚点、相关概念指南 | 确定性 `--check`、完整性 fixture、站点构建和检索规模报告 |
+| Agent 指令或 skill（技能） | 在没有陈旧复制值的情况下执行一项工作流 | 范围、权威链接、必需决策、仅在此处归属时写入精确命令 | 元数据或链接检查，以及针对复制机器值的聚焦测试 |
+| 提议或已实现 Agent Note | 理解决策、取舍与状态 | 问题、提案或决策、备选方案、验收或后果 | 既有生命周期、格式、配对和取代检查；语义时效性由评审负责 |
+
+该表应归属一份规范质量参考。`docs/AGENTS.md` 只保留每次编辑文档都需要的简短常驻规则，并链接到该参考。这样可以创造预算余量，而不是把另一份完整标准放进 agent 上下文。
+
+### 生成参考的入口层与细节层
+
+每份生成参考都应在穷尽式输出之前提供紧凑入口层：范围、预期查询、分组或索引、概念指南的直接链接，以及生成器或检查命令。生成器应报告页面词数、条目数、标题数和最大章节。当一次查询需要扫描无关分组，或单页主导 agent 上下文时，该页面便跨过评审阈值；随后，归属者按照源元数据中已有的稳定领域拆分页面，而不是按任意词数切片。
+
+首个原型应选择一个大型目录和一个混合子系统页面。在进行全语料拆分前，它应比较查询步骤、生成 diff 大小、构建时间、路由稳定性，以及代表性问题所需的 agent 上下文。路由移动时，既有锚点需要保留别名。
+
+### 执行切片
+
+1. 创建并验证 `dsh-doc`，再把 `session-persistence-sqlite` README 对改写为行对齐、带元数据的原型，同时不改变运行时事实。
+2. 用新人、用户、开发者和 agent 任务评审渲染后的原型；先修订 skill，再在其他位置强制执行该格式。
+3. 添加聚焦的元数据、章节顺序、行对齐、链接解析和配对 fixture。在每个合并与恢复消费方都有替代支持前，保留伴随文件。
+4. 把已接受的常驻规则提取到一份规范质量参考，将 `docs/AGENTS.md` 精简到目标以下，并且一次只组织一个内聚的 `docs/` 主题，同时原子地修复链接与导航。
+5. 在 `config-catalog.md` 和 `docs/subsystems/core.md` 上制作生成参考入口层与细节层分离的原型；只有实测查询成本下降且没有丢失事实或造成路由扰动，才把确认后的模式应用到其他位置。
+
+该顺序使每项变更都能独立评审。前三个切片在不重写语料的情况下改进标准与正确性；生成文档原型则在更广的信息架构变更前提供证据。
+
+切片 1–3 已按此形式交付：`dsh-doc` 成为合并后的标准（`dsh-doc-standards` 与 `dsh-doc-site-sync` 已并入其中，站点工作流携带修正后的侧边栏值），`session-persistence-sqlite` README 对是参考示例，`pnpm run test:docs` 强制执行元数据、配对与快速文档检查。切片 4–5 仍待完成。
+
+### 非目标
+
+本提案不缩减穷尽式事实，不合并受众层级，不发布内部决策记录，不恢复 Agent Note 索引，不为了文件数对称而拆分紧密耦合的规则，也不把此次审计当作用户研究。在替代方案通过等价的恢复与渲染检查前，本提案不删除现有配对或链接基础设施。
+
+## 考虑过的备选方案
+
+**为每份文档设置统一词数上限。**不予采纳，因为穷尽式参考条目、公开约定和决策理由可以既长又正确。对这些文档职责而言，入口路径长度与查询成本才是相关约束。
+
+**强制使用统一页面模板或受众前置元数据。**不予采纳，因为这会给生成页面、包参考和简短指令增加形式，却不能证明读者成功。标准按文档职责定义结果，仅在 `kind` 能选择具体包文档标准时使用它，并且只添加聚焦检查或评审会消费的字段。
+
+**把可读性分数作为质量门禁。**不予采纳，因为公式会惩罚精确技术术语，却无法发现错误所有权、遗漏失败行为、陈旧命令或破损的读者路径。
+
+**立即重写或拆分全部语料。**不予采纳，因为现有系统在机制上健康，许多长参考也确实应保持穷尽。原型应先证明检索有所改善，再扩散路由和翻译扰动。
+
+**保留现有门禁，让评审负责友好程度。**不予采纳，因为陈旧工作流值和预算策略不一致说明，仅凭评审无法保留复制的语义事实，而现有门禁也不询问读者是否能完成任务。
+
+## 验收标准
+
+- 一份规范质量参考按文档职责定义简短、直观、友好、准确和便于 agent 阅读的文档。
+- `.agents/skills/dsh-doc` 通过验证，并直接链接其元数据、结构或层级及评审或原型参考，而不在 `SKILL.md` 中复制这些参考的详细规则。
+- SQLite README 对展示可搜索 YAML、Summary、Table of Contents、从用户到开发者的渐进结构、Further Exploration、结尾 Dev Note、结构一致性和精确行数相等，同时保留已验证的包约定。
+- `docs/AGENTS.md` 链接该参考，仍足以充当常驻指令，并低于其目标且至少保留 5% 余量。
+- 根级用户路径、Web 快速开始、第一个插件教程、贡献者设置和架构概览各自给出一个可观察结果与验证归属者，同时不复制实现细节。
+- 预算 manifest 同时记录目标与临时上限，其检查会报告或拒绝违反余量或棘轮规则的状态。
+- 文档站工作流不再包含复制的无效侧边栏名称或章节归属声明，并有聚焦测试防止复发。
+- sidecar 继续作为唯一一致性记录，因为它能保留同等权威、上次确认文本恢复、自动合并安全、生成区域记录和归档封存，同时不会在正文文件中制造冲突。
+- 一个已接受的仓库根级链接格式在迁移相对链接前能在 GitHub 与文档站正确渲染，并继续接受本地目标或锚点检查。
+- 一个大型独立生成目录页和一个混合子系统页面展示紧凑入口层与更低的实测查询成本，同时保留穷尽式生成事实、稳定链接、双语配对和确定性新鲜度。
+- `pnpm run doc-sync`、`pnpm run lint`、聚焦的新检查和 `git diff --check` 均通过。
+
+## 风险
+
+- 元数据可能沦为样板；因此包 README 检查只允许具有现行检索、模板选择或双语一致性消费方的字段。
+- 硬性句长限制可能割裂说明，或把条件与后果分开。受控英语的词数限制仅作评审提示，精确约定优先于句长。
+- 精确行对齐可能迫使译者写出不自然的正文；评审必须保护含义，并可同时修订两侧，而不是削弱其中一侧。
+- 拆分生成参考可能增加路由与链接维护；原型必须保留别名并衡量取舍。
+- 语义检查可能膨胀成阻塞正当变更的仓库拓扑扫描器；检查应覆盖高风险复制值和代表性路径，而正文含义仍由评审负责。
+- 包 README 的快速参考表会手工重复部分配置默认值；在源驱动检查接管之前，评审者必须对照源码和生成配置目录验证变更值，并让这些表保持精选而非穷尽。
+- 为缩短 agent 上下文而优化可能使人类参考变得碎片化；每次拆分都需要一个稳定概念归属者和一条明确导航路径。
+- 永久的 Dev Note 可能变成第二份队列或陈旧历史堆积；完成工作时必须提升持久事实并删除已解决的过程内容。
+- 本次审计使用仓库结构、门禁和代表性页面，而不是用户研究。在广泛推广之前，维护者应通过真实的新人、用户、开发者和 agent 任务验证提议的读者结果。

-description: 'Use when writing, moving, reviewing, or auditing documentation in the deepseek-harness repo — choosing hierarchy and detail, separating tutorials from references, checking tutorial progression, trimming doc slop, responding to a verify-doc-budgets failure, or requests like "improve the docs", "audit the docs", "where should this be documented", or "this doc is too long".'
----
-
-# Applying the DeepSeek Harness Documentation Standard
-
-The documentation rules live in [docs/AGENTS.md](../../../docs/AGENTS.md). This workflow covers placement, corpus audits, budgets, and validation across Markdown, JSDoc, and code comments. It is guidance, not a script; use [dsh-prose-standard](../dsh-prose-standard/SKILL.md) for required coverage and editorial judgment, and never treat length alone as a defect.
-
-## Sources of truth (read, don't re-summarize)
-
-- [docs/AGENTS.md](../../../docs/AGENTS.md) — hierarchy, tutorial/reference forms, taxonomy, budgets, and slop checklist.
-- [.agents/notes/README.md](../../notes/README.md) — when a decision earns an Agent Note, how to file it, and what goes inside one (the header block, per-lifecycle skeleton, and Alternatives-considered mandate, gated by `verify-agent-note-format`); [docs/postmortem/README.md](../../../docs/postmortem/README.md) — when an incident earns a postmortem.
-- [docs/i18n/README.md](../../../docs/i18n/README.md) — the bilingual pairing rules; editing either side of a pair obligates the counterpart in the same change.
-- Root [AGENTS.md](../../../AGENTS.md) — the standing orders whose budget discipline this skill protects.
-- [Archived Agent Notes](../../notes/archived/AGENTS.md) — frozen historical snapshots excluded from editorial maintenance and evolving documentation gates.
-
-## Review structure before prose
-
-Apply the standard's authoring order to every human-facing document in scope. Do not apply this structural pass to Agent Notes. Classify a postmortem as a reference scoped to one incident; preserve its required chronological evidence without treating chronology as a teaching sequence.
-
-1. Locate the document in the repository and navigation trees. State its own subject and identify its direct children.
-2. Set the permitted level of detail. Keep full detail about the document's subject, summarize direct children by purpose, responsibility, and high-level behavior, and move deeper explanations to their owning descendants with links. Treat test infrastructure as descendant-owned unless it is the document's subject.
-3. Classify the document from its intended use, not its path or title. A tutorial must lead through ordered work to an observable outcome; a reference must support lookup within an explicit scope without requiring sequential reading.
-4. For a tutorial, privately classify the starting reader and concepts as beginner, intermediate, or advanced. Trace each concept to its prerequisites, reorder premature material, and move optional advanced detail to a later tutorial or reference.
-5. Split substantial mixed forms. Put a small secondary form in a clearly labeled section.
-
-Then check constraints that make placement expensive or wrong:
-
-- Paired docs (`pnpm run verify-translation-pairing --list`) cost a zh counterpart update and a `--write` re-record on every edit — prefer an unpaired home for content that will churn. Verbatim code blocks are byte-exact across the pair: copy a corrected fence into both files instead of translating its comments independently.
-- Generated catalogs are never hand-edited; if the fact belongs there, change the generator's source.
-- Before renaming or moving any doc, grep for inbound references: `verify-md-links` catches Markdown link targets AND `#fragment` anchors onto Markdown files (heading slugs and explicit `<a id>`), and `verify-doc-refs` catches `docs/*.md` citations in TypeScript comments; anchors cited from TypeScript strings still need a manual grep when their output never reaches gate-scanned Markdown.
-- A move is atomic: remove from the old home, add to the new home, and fix every inbound link in the same change.
-
-## Audit the corpus
-
-After the structural pass, hunt the standard's slop checklist with the cheapest probes first. Verify and fetch the PR's live base, then run `pnpm --silent run change-scope --base <verified-base-ref>` to identify committed and dirty paths before applying semantic judgment. After a retarget or base merge, rerun the report and audit prose introduced by the new base.
-
-1. Measure: `pnpm run verify-doc-budgets --list`, then `git ls-files '*.md' ':(exclude)vendor/**' | xargs wc -w | sort -rn | head -30` to spot unbudgeted outliers.
-2. Hunt reasoning-transcript leakage — narrated history, dead design-session citations, review choreography, control-flow narration, test walkthroughs — with [dsh-trim-cot-leakage](../dsh-trim-cot-leakage/SKILL.md), which defines the taxonomy, recall batteries, and rules for what to keep or delete. Preserve only a non-obvious contract or durable rationale; the same rationale repeated beside sibling methods keeps one home.
-3. Hunt duplication by grepping distinctive phrases. Keep one home and replace other copies with links.
-4. Replace hand-written catalogs, test/status inventories, and JSDoc restatements with the authoritative tree, script, or generated reference.
-5. In `implemented/` Agent Notes, remove migration plans, acceptance-task checklists, and future-tense spec language. Keep concise verification contracts that identify the behaviors and tiers pinning the shipped decision, plus named coverage gaps.
-6. If removing prose changes a promised behavior rather than its explanation, use a proposed Agent Note first (follow [dsh-find-simplifications](../dsh-find-simplifications/SKILL.md)).
-
-Exclude `.agents/notes/archived/` from corpus audits and edits. Active prose may repair, redirect, or delete an inbound link, but never follow an archive-wide cleanup into the frozen target.
-
-Keep every load-bearing rule, preferably as one to three lines plus a link to its rationale. Cut stories, duplicates, status notes, and the path used to derive the rule. Do not create a new explanation merely to relocate disposable reasoning.
-
-## When verify-doc-budgets goes red
-
-Apply the ordered relocate-condense-raise policy in [docs/AGENTS.md](../../../docs/AGENTS.md); this skill only supplies the workflow probes above.
-
-## Validation and PR hygiene
-
-Run at least `pnpm run doc-sync`, `pnpm run lint`, and `git diff --check`; JSDoc changes may regenerate catalogs. If a paired doc changed, follow the [lightweight routine path](../../../docs/AGENTS.md#writing-rules) and run `pnpm run verify-translation-pairing --write <pair>`. The PR body should give word deltas, explain any deliberately long exception, and list checks.

+# DeepSeek Harness documentation
+
+## Summary
+
+The DeepSeek Harness documentation standard: make every page searchable, newcomer-readable, and exact enough for agents and maintainers, and keep the documentation website a tested projection of repository Markdown. Apply repository `AGENTS.md` files and executed gates first, then this workflow for kind-mapped metadata, progressive detail, line-aligned bilingual pages, corpus audits, and website publication. Preserve one owner per fact: source, tests, generated catalogs, package READMEs, guides, Agent Notes, and scratch each keep their own kind of truth. The `session-persistence-sqlite` README pair is the reference example of the format.

+## Workflow
+
+Follow this sequence for each requested scope. Keep the common reader path brief, but do not delete failures, ownership, limitations, or other required contracts merely to reduce words.
+
+1. Read root and more-specific `AGENTS.md`, [the documentation standard](../../../docs/AGENTS.md), the target page, its source/tests, navigation owner, and bilingual record.
+2. Classify the page by one primary job and reader: product quick start, user task guide, contributor tutorial, architecture overview, package/subsystem reference, generated reference, agent instruction, decision record, or scratch.
+3. Place the page at its nearest owner. Keep package contracts beside package code; use `docs/` for cross-package learning, user, developer, architecture, discussion, and expiring scratch material.
+4. Define the reader's starting state, observable outcome, likely failure, recovery path, and next useful depth before writing details.
+5. Add or revise YAML metadata — assign the `kind` that maps to the template for this document's job — then write `Summary`, `Table of Contents`, user-facing content, developer-facing content, optional `Further Exploration`, and final `Dev Note` in that order where the document type permits.
+6. Update the bilingual counterpart in the same pass. Keep headings, lists, tables, code, links, frontmatter layout, and physical line count aligned.
+7. Verify every claim against code, tests, generators, package metadata, or a current decision owner — and run the operations the page instructs, per the fact-check procedure below. Update the owner before any derivative artifact.
+8. Run focused checks, then `pnpm run test:docs`, `pnpm run doc-sync`, `pnpm run lint`, and `git diff --check`; re-read the complete diff for correctness and then for brevity and repository fit.
+
+## Fact-check procedure: test, do not assume
+
+Documentation states how the product behaves today, and the only admissible evidence for an operation claim is having run it. This procedure is mandatory for every new document and every new paragraph that claims an operation, command, default, error, or platform difference.
+
+1. **Classify the subject before writing install guidance.** Read the facts, never the folder name: `package.json` for a `dsh.bundle.patch` declaration, and the entry file for the plugin shape (`apply` export or a default service export is a plugin; a plain module API is a library). A bundle installs with `dsh plugin --profile <name> add <package>` and is the only package shape for which that command activates a profile layer; a plugin mounts as a `cordis.yml` row; a library is a dependency with no install path of its own. Packages with special status (libraries, bundles) get their own README template — never a plugin README with install guidance that does not apply.
+2. **Run every claimed operation against the current checkout.** Execute each CLI command, config snippet, and profile or patch example exactly as the document will show it; write down only what you observed, including the exact output, warnings, and failure modes. If a claim depends on a key or a network you do not have, say so and name the verification owner instead of asserting the behavior.
+3. **Delete what you could not reproduce.** Never carry a command, field, default value, or behavior from memory, analogy, or a neighboring package's README. When a claim fails to reproduce, fix the claim — not the test.
+4. **Check old docs against latest master.** Before revising pre-existing pages, `git fetch origin` and compare the section against `origin/master`; the pairing sidecar recovers the last-confirmed text of either side. A stale statement on master is still wrong: correct it against the code, not against the old prose.
+5. **Re-record the pair after every edit.** Each paired edit re-runs `pnpm run verify-translation-pairing --write <pair>` so the sidecar tracks the confirmed pair.
+
+## Kind system and templates
+
+The `kind` frontmatter field selects exactly one README template. Every kind in [the metadata reference](references/metadata-links-i18n.md#the-kind-system) maps to one template file in [`templates/`](templates/), and every template backs exactly one kind; the documentation check derives the expected kind from the same mechanical facts.
+
+- `package-group` → [templates/package-group.md](templates/package-group.md): group maps (`packages/README.md`, `packages/<group>/README.md`) — orient the family, map its direct packages, link package-owned details.
+- `package-reference` → [templates/package-reference.md](templates/package-reference.md): a Cordis plugin or service package — mount configuration, the config table, folded implementation, Model Experience and Known Limitations in the gate-owned forms.
+- `package-library` → [templates/package-library.md](templates/package-library.md): a package with no plugin surface — consumer entry points, no profile-install path, no mount configuration.
+- `package-bundle` → [templates/package-bundle.md](templates/package-bundle.md): a package declaring `dsh.bundle.patch` — the verified `dsh plugin` install path, layer semantics, patch document.
+
+Open the template before writing and follow its skeleton and rules; it states what the kind is, how the page is structured, and the fact checks each section owes. Add a new kind only together with a distinct template file, a documented repository position or declared owner, and a focused check that maps documents to it.
+
+## Voice rules
+
+These rules decide what a section may say. They apply to every authored human-facing page, and to package READMEs with particular force.
+
+- **Summary says what the subject does.** The opening `Summary` and the user-facing sections describe what a user or agent can DO with the subject — outcomes, benefits, when to choose it, main cost — never its role, type, or internal identity. "The seam registers `ctx.x` and appends `x/event` records" is identity narration; "you can save a note per message and it survives restarts" is what it does.
+- **Developer sections explain, never enumerate.** Folded implementation content covers the overall design concept, architecture, and hand-waving dataflow — enough to understand how the package works — and links code for exact detail. No full API catalogs, exhaustive column lists, event-payload enumerations, or JSDoc restatement inside the folds.
+- **Dev Note is the only slop zone.** Partial ideas, scratches, undecided directions, measured artifacts, and working hypotheses live only in the final Dev Note, marked explicitly non-authoritative. Every other section is polished, current-state prose.
+- **Current state only.** No compatibility shims, migration talk, or history ("previously", "now", "no longer", renamed) outside the Dev Note; the codebase as it is today is the only subject.
+- **Use controlled technical English.** Give each sentence an explicit actor and one main action when ambiguity can change behavior. Reuse one term per concept, prefer direct verbs, split stacked instructions and conditions, and preserve modality and exceptions. Apply the non-certified, ASD-STE100-inspired discipline in [the page-style reference](references/style.md#controlled-technical-english). Do not force a shorter sentence when precision would fall.
+
+## Quality criteria
+
+Use these definitions in review. Each section opens with a short orienting paragraph before subsections or exhaustive detail.
+
+- **Brief:** the common path contains only facts needed for its outcome; exhaustive truth remains one direct link or detail layer away.
+- **Intuitive:** prerequisites precede dependent concepts, one next action is obvious, and headings use terms readers search for.
+- **Friendly:** readers can recognize success, understand risk before acting, recover from likely failure, and choose whether to continue deeper.
+- **Accurate:** each durable claim has one owner and a verification path proportionate to its risk.
+- **Agent-readable:** metadata, stable headings, anchors, terminology, ownership, and current/proposed status support targeted retrieval without loading the corpus.
+- **Newcomer-complete:** a professional engineer with no repository context can reconstruct the relevant architecture or feature through three to five linked pages.
+
+Do not apply a universal word limit to exhaustive references. Measure entry-path length, unrelated material scanned for one lookup, largest section, heading count, and page size; split by an existing domain owner when retrieval cost is high.
+
+## Audit the corpus
+
+Read, do not re-summarize, the owning contracts: [docs/AGENTS.md](../../../docs/AGENTS.md) for hierarchy, tutorial/reference forms, taxonomy, budgets, and the slop checklist; [.agents/notes/README.md](../../notes/README.md) for Agent Note lifecycle; [docs/i18n/README.md](../../../docs/i18n/README.md) for the bilingual pairing rules; and [root AGENTS.md](../../../AGENTS.md) for standing orders. Exclude `.agents/notes/archived/` from audits and edits — archived notes are frozen history.
+
+Apply the standard's authoring order to every human-facing document in scope (not to Agent Notes): locate the document and state its own subject; set the permitted detail level and move deeper explanations to owning descendants with links; classify tutorial or reference from intended use, not path; for a tutorial, order concepts by prerequisite and difficulty; split substantial mixed forms. Then check placement constraints: paired docs cost a counterpart update and a `--write` re-record on every edit; generated catalogs are never hand-edited; a move is atomic with every inbound link repaired in the same change.
+
+After the structural pass, hunt the slop checklist with the cheapest probes first. Use [dsh-trim-cot-leakage](../dsh-trim-cot-leakage/SKILL.md) for reasoning-transcript leakage, grep distinctive phrases to find duplicated rules, replace hand-written catalogs and status inventories with their authoritative owners, and remove migration plans and future-tense spec language from implemented Agent Notes. Measure outliers with `pnpm run verify-doc-budgets --list` and a word-count scan; if removing prose changes a promised behavior rather than its explanation, propose the behavior change first (follow [dsh-find-simplifications](../dsh-find-simplifications/SKILL.md)). Keep every load-bearing rule, preferably as one to three lines plus a link to its rationale; do not create a new explanation merely to relocate disposable reasoning.
+
+## Wordcount budgets
+
+`pnpm run verify-doc-budgets` compares standing documents against ceilings in [scripts/doc-budgets.manifest.json](../../../scripts/doc-budgets.manifest.json); a red gate follows the ordered relocate-condense-raise policy in [docs/AGENTS.md](../../../docs/AGENTS.md#wordcount-budgets). Ceilings are guardrails, not reduction targets: at or below target, retain at least 5% headroom; raise a ceiling only when the words need the space, and justify the manifest diff in the PR.
+
+## Website publication
+
+The website is a tested projection, never a second copy: [website/docs.ts](../../../website/docs.ts) is the explicit public allowlist mapping canonical `docs/` sources into route trees, [scripts/project-doc-site.ts](../../../scripts/project-doc-site.ts) rewrites them into the disposable `website/.generated/` tree, and VitePress builds that tree. Repository Markdown stays the only editable content source; translations stay sibling pairs (`foo.md`, `foo.zh.md`, `foo.i18n.yaml`), never locale directories. Edit an already published page in its canonical source only; add one manifest entry for a new page; update source, manifest entry, and inbound links atomically for a move or removal; never edit `website/.generated/`, `website/.cache/`, or `website/.dist/`. Set every `DocsPage` field deliberately and honor the projector's link rules; see [references/website-sync.md](references/website-sync.md) for the fields, sidebar collections, and preview commands. Synchronizing content into the build does not publish it: deployment stays a separate, explicitly requested step.
+
+## Detailed references
+
+Load only the reference needed for the task. Each reference links directly from this file so the skill has no deep reference chain.
+
+- [Metadata, links, and bilingual pairs](references/metadata-links-i18n.md): README frontmatter, the kind system and its derivation, description semantics, repository paths, line alignment, and the sidecar record.
+- [Page structure and hierarchy](references/structure-hierarchy.md): mandatory section order, section summaries, user-to-developer progression, docs tree placement, small rule files, Further Exploration, and Dev Note ownership.
+- [Page style](references/style.md): short Summary, `-----` section separators, foldable content sections, and emphasis discipline.
+- [Review criteria](references/review.md): newcomer test, evidence checks, package README review, the reference example, and verification commands.
+- [Website publication](references/website-sync.md): manifest fields, projector link rules, preview and validation, and deployment separation.
+
+The four README templates in [`templates/`](templates/) are the working skeletons for the four `kind` labels; open the one your document's kind names before writing.
+
+Use [dsh-prose-standard](../dsh-prose-standard/SKILL.md) for sentence-level contract coverage and editorial judgment. The `session-persistence-sqlite` README pair ([English](../../../packages/session/session-persistence-sqlite/README.md), [Chinese](../../../packages/session/session-persistence-sqlite/README.zh.md)) is the reference example: searchable YAML, Summary and Table of Contents, user-to-developer progression with a folded developer section, Further Exploration, canonical Model Experience and Known Limitations sections, and a final Dev Note.
+
+## Validation
+
+Validate the affected format, not merely Markdown syntax. A strong promise needs a focused valid fixture and an invalid fixture that proves the top-level gate can fail.
+
+- README metadata: parse YAML, map `kind` to its template and document standard, reject `name`, `audience`, ungoverned `tags`, and README-local `i18n` metadata, and reject missing or advertisement-style descriptions.
+- Bilingual pages: verify structure, exact line count, terminology, link parity, and the sidecar record.
+- Tutorials: exercise the documented entry path or name an explicit manual verification owner.
+- Generated references: run the deterministic freshness check and report retrieval-size measures.
+- Package READMEs: run model-experience and limitation checks, then package-focused tests when behavior claims changed; re-run every command the README instructs before merging a claim about it.
+- Skills: run the repository's skill-invocation metadata check.
+
+Run `pnpm run test:docs` for the quick comprehensive documentation checks (pairing, wrap, links, README gates, budgets, skill metadata, Agent Note gates) before the full `pnpm run doc-sync`.

+# Metadata, links, and bilingual pairs
+
+## Summary
+
+README metadata is a retrieval and template-selection interface, not a miniature report or advertisement. The `kind` field selects exactly one README template that exists in this skill and maps to the document standard; the frontmatter carries no field that a filename convention or an executed gate already owns. Bilingual pages keep equal authority, one-to-one structure, and exact physical line alignment. The `*.i18n.yaml` sidecar records the last-confirmed pair and supports automatic merges. Link syntax must render correctly on GitHub and the documentation site, so repository links stay renderer-valid relative URLs.
+
+## Table of Contents
+
+- [README metadata](#readme-metadata)
+- [The kind system](#the-kind-system)
+- [Description quality](#description-quality)
+- [Repository links and path mentions](#repository-links-and-path-mentions)
+- [Bilingual line alignment](#bilingual-line-alignment)
+- [Bilingual consistency records](#bilingual-consistency-records)
+- [Dev Note](#dev-note)
+
+## README metadata
+
+Start every authored README with YAML frontmatter. Permit custom fields, but keep common fields stable enough for search and indexing.
+
+```yaml
+---
+description: "Example capability for users and maintainers choosing, configuring, or debugging the package."
+kind: "package-reference"
+---
+```
+
+`description` and `kind` are required for package README pairs. The page title and package manifest already own the name, while the document job and its reader path express the audience; duplicating either in frontmatter adds no retrieval value. The counterpart path comes from the sibling filename (`README.zh.md`), and the sidecar owns pair state, so README-local `i18n` metadata is redundant. Do not add `tags` until a repository-owned taxonomy and search consumer justify them beyond description and full-text search. Keep keys lowercase and hyphenated unless an existing owner defines another spelling, and do not copy volatile code inventories into frontmatter.
+
+## The kind system
+
+`kind` selects the document template directly; every kind maps to exactly one template that exists in this skill, and no template exists without a kind. Derive the kind mechanically, in this order:
+
+1. The README is `packages/README.md` or `packages/<group>/README.md` → `package-group`.
+2. The package manifest declares `dsh.bundle.patch` → `package-bundle`.
+3. The package is in the audited library registry of `scripts/doc-standard.spec.ts` → `package-library`.
+4. Everything else — a service default export or an `apply` plugin — is `package-reference`.
+
+| `kind` | Repository position | Template | Standard |
+|---|---|---|---|
+| `package-group` | `packages/README.md`, `packages/<group>/README.md` | [package-group.md](../templates/package-group.md) | Group map: orient the capability family, map its direct packages, explain composition relationships, and link package-owned details. |
+| `package-reference` | `packages/<group>/<package>/README.md` with a plugin entry | [package-reference.md](../templates/package-reference.md) | Package contract: follow the [package README review standard](review.md#package-readme-review) and the canonical [package documentation requirements](../../../../docs/cookbook/adding-a-package.md#4-write-the-package-readme). |
+| `package-library` | `packages/<group>/<package>/README.md` with a plain module entry | [package-library.md](../templates/package-library.md) | Library contract: consumer entry points and boundaries; no profile-install path and no mount configuration. |
+| `package-bundle` | `packages/<group>/<package>/README.md` declaring `dsh.bundle.patch` | [package-bundle.md](../templates/package-bundle.md) | Installable layer: the verified `dsh plugin` install path, layer semantics, and patch document. |
+
+Before assigning `package-library` or `package-bundle`, inspect the facts: read `package.json` for `dsh.bundle.patch` and `src/index.ts` for the entry shape (`apply` export or a default service export is a plugin; a plain module API is a library). `dsh plugin --profile <name> add <package>` installs any npm dependency, but the profile reconcile activates a layer only for a package that declares `dsh.bundle`; never present that command as an install path for a library or a plain plugin. The documentation check derives the expected kind from these same facts, rejects another value, and rejects `name`, `audience`, `tags`, and README-local `i18n` metadata. Add a new kind only with a distinct template, an unambiguous repository position or declared owner, and a focused check that maps documents to it.
+
+## Description quality
+
+Agents search frontmatter `description` values to shortlist pages before loading full documents. Write each value like a Skill description: state what the page covers and when a reader should open it. Use one or two concrete sentences, include searchable domain terms, and distinguish the page from nearby owners. Do not summarize every section, claim superiority, repeat the title, advertise vaguely, preserve change history, or write a technical status report.
+
+Good: `SQLite session persistence for deployments and maintainers choosing, configuring, or debugging the opt-in packed-row backend.`
+
+Weak: `The best and most advanced SQLite storage implementation with lots of optimizations.`
+
+## Repository links and path mentions
+
+Keep link destinations machine-checkable and mentions context-relative. Use fragment-only links for the current page's menu. Use full URLs for external resources.
+
+The desired internal-link model names a target from the repository root, but a leading `/docs/...` Markdown URL resolves outside the repository on GitHub, remains untouched by the website projector, and is skipped by `verify-md-links`. Until a repository-owned resolver supports root paths in every renderer, use the current renderer-valid relative URL in Markdown links and write logical path mentions such as `docs/` or `packages/session/` relative to the discussion. Never adopt an unchecked leading-slash link merely to resemble an absolute path.
+
+## Bilingual line alignment
+
+Keep English and Simplified Chinese equally authoritative. Match frontmatter key order, headings, blank lines, paragraphs, list items, tables, code fences, link targets, and total physical line count one to one. The English side points every relative link at the `.md` target; the Chinese side points it at the `.zh.md` sibling when that counterpart exists and falls back to the `.md` target otherwise — the pairing gate compares `.md` and `.zh.md` targets as the same document. Translate prose naturally within its corresponding line; do not hard-wrap either language. Keep code blocks byte-identical and reposition first-use terminology annotations without changing line structure.
+
+Line equality is a structural check, not proof of faithful meaning. Review still owns completeness, terminology, natural language, and whether each line expresses the same proposition.
+
+## Bilingual consistency records
+
+Keep the `*.i18n.yaml` sidecar for every bilingual pair. `verify-translation-pairing` consumes its Git blob hashes for last-confirmed-text recovery, verifies structure and exact line alignment, supports automatic merging, records generated regions, and seals archives. Re-record it with `pnpm run verify-translation-pairing --write <pair>` after either language changes. Do not copy content hashes into README frontmatter: independent edits would change the same header line and turn otherwise mergeable prose into an owner-file conflict.

+# Review criteria
+
+## Summary
+
+Review documentation by whether a reader completes an outcome, not by whether every template heading exists. Verify prose against code and tests, preserve exact contracts, and keep package READMEs useful to consumers while exposing enough implementation detail for maintainers. Run current repository gates; the `session-persistence-sqlite` README pair is the reference example of the format.
+
+## Table of Contents
+
+- [Newcomer test](#newcomer-test)
+- [Evidence review](#evidence-review)
+- [Package README review](#package-readme-review)
+- [Reference example](#reference-example)
+- [Verification](#verification)
+- [Dev Note](#dev-note)
+
+## Newcomer test
+
+A professional engineer with no repository context should answer the following after three to five linked pages: what the product or feature does, how to run or use it safely, where its state lives, which component owns it, how it fails, and where to change it. If the reader must inspect source merely to discover the public flow, restore the missing explanation. If the reader must absorb unrelated internals, move those details deeper.
+
+## Evidence review
+
+Check each material statement against its strongest owner. Use package metadata for names and entry points, public types and JSDoc for API contracts, runtime code for behavior, tests for exercised failure paths, generated catalogs for exhaustive inventories, and active Agent Notes for rationale. Never treat a prior README, discussion, or report as stronger than current code and tests.
+
+For every operational claim — a CLI command, a config snippet, a default value, an error message, a platform difference — the evidence is running it, not reading it. Execute the exact command or mount the exact configuration against the current checkout before the page may state its behavior; quote only observed output, warnings, and failures. Claims that depend on unavailable keys or networks name their verification owner instead of asserting behavior. For pre-existing pages, compare against latest `origin/master` and re-verify stale statements against code.
+
+Classify the package before reviewing its install guidance: `dsh.bundle.patch` in `package.json` makes it a bundle (installable via `dsh plugin --profile <name> add <package>`, the only shape that command activates as a layer); an `apply` export or default service export makes it a plugin (mounted as a `cordis.yml` row); a plain module API makes it a library (a dependency with no install path). Reject install guidance written for another shape.
+
+Retain a statement only when it helps the target reader act, reason, or avoid misuse. Move rationale, history, test walkthroughs, duplicate catalogs, and unrelated package detail to their owners.
+
+## Package README review
+
+Require the following without forcing one universal internal heading set:
+
+- searchable YAML metadata with a precise `description` and the mechanically derived `kind` (`package-group`, `package-reference`, `package-library`, or `package-bundle`);
+- a three-to-five-sentence Summary that says what the subject DOES for its user or agent reader, with a linked Table of Contents;
+- controlled English with explicit actors, stable terms, direct verbs, separated instructions and conditions, and unchanged modality;
+- when to choose or avoid the package;
+- a smallest safe configuration or usage path when one exists — for a bundle, the verified `dsh plugin` install path; for a library, the consumer entry point; never profile-install guidance for a shape that does not take it;
+- observable behavior, failures, durability, security, and performance limits relevant to consumers;
+- developer-facing ownership and data/lifecycle design at concept level — overall design, architecture, hand-waving dataflow — that cannot be recovered cheaply from public types, with code links for exact detail;
+- canonical Model Experience and Known Limitations sections required by package policy;
+- newcomer-facing Further Exploration where adjacent docs materially help;
+- a final non-authoritative Dev Note as the only home for partial ideas, scratches, and undecided directions.
+
+Do not restate JSDoc or generated catalogs. Link the owner and explain only the decision or relationship needed locally. Reject any user-facing section that narrates internals (function subjects, event streams, data flow) and any fold that enumerates APIs instead of explaining the concept.
+
+## Reference example
+
+The `session-persistence-sqlite` README pair ([English](../../../../packages/session/session-persistence-sqlite/README.md), [Chinese](../../../../packages/session/session-persistence-sqlite/README.zh.md)) demonstrates the format in production: searchable YAML whose `kind` selects this package-reference standard, a five-sentence Summary, a linked Table of Contents, a user-facing use section (choice, sizing, configuration, migration, safe operation) separated by horizontal rules and followed by a GitHub-native `<details>` fold under the developer section title (design philosophy, source map, schema tables, write path, read and recovery), Further Exploration, canonical Model Experience and Known Limitations sections, and a final folded Dev Note holding non-authoritative working context such as the annotated benchmark artifact and undecided future directions. Use its structure, evidence standards, and bilingual alignment as the model for package READMEs and cross-package pages; ground every claim the way it grounds the benchmark numbers in the Agent Note.
+
+## Verification
+
+Run the smallest focused checks while iterating, then the standing documentation checks:
+
+```sh
+pnpm run test:docs
+pnpm run verify-translation-pairing --write <pair>
+pnpm run doc-sync
+pnpm run lint
+git diff --check
+```
+
+Also run the repository's skill-invocation metadata check for skill changes and compare English/Chinese physical line counts for a line-aligned pair. Re-read the final diff once for factual completeness and once for brevity, navigation, and ownership.
+
+## Dev Note
+
+None.

+# Page structure and hierarchy
+
+## Summary
+
+Each page gives a newcomer a short front door before it exposes operational or implementation depth. Cross-package learning and engineering material lives under a deliberate `docs/` hierarchy, while package contracts stay beside code. Small rule files own one independently searchable requirement, but arbitrary fragmentation is not a goal. The final Dev Note isolates active working context from the stable explanation above it.
+
+## Table of Contents
+
+- [Page order](#page-order)
+- [Section progression](#section-progression)
+- [Documentation hierarchy](#documentation-hierarchy)
+- [Small rule files](#small-rule-files)
+- [Further Exploration](#further-exploration)
+- [Dev Note ownership](#dev-note-ownership)
+- [Dev Note](#dev-note)
+
+## Page order
+
+Use this order for authored human-facing pages when the format owner permits it. Generated artifacts may generate the same entry sections, while Agent Notes and postmortems retain their repository-defined skeletons.
+
+1. YAML metadata.
+2. H1 title.
+3. Language switcher for a bilingual page.
+4. `## Summary`: three to five explanatory sentences stating what the subject is, why a reader would care, the main operating model, and the most important boundary.
+5. `## Table of Contents`: links to the page's H2 sections; keep it navigational rather than descriptive.
+6. Stable content, ordered from user-facing use to developer-facing design and operational detail.
+7. Optional `## Further Exploration` for newcomer-oriented links to adjacent subjects.
+8. Final `## Dev Note` for non-authoritative active working context.
+
+Do not force a Summary/Table of Contents wrapper around tiny machine-owned files, generated fragments, or formats whose executed parser defines another header. State the exception in the format owner rather than creating invalid output. The package README gate requires `Model Experience` and `Known Limitations and Deferred Work` as the final two H2 sections: place `Further Exploration` before them and end with a final `### Dev Note` inside the limitations H2.
+
+## Section progression
+
+Open every substantive H2 with a short orienting paragraph before tables, code, or H3 subsections. Explain the section's subject and decision-relevant point; do not repeat its complete contents.
+
+Within a page, order content by reader depth:
+
+1. Basic use: when to choose the feature, required inputs, shortest safe example, observable success, and likely recovery.
+2. Advanced use: configuration choices, limits, operations, and integration behavior.
+3. Developer detail: ownership, lifecycle, data model, failures, performance, security, and extension points worth maintaining.
+
+Fold heavy developer detail and the final Dev Note behind `<details>` blocks with the section titles visible (mechanics in [style.md](style.md)).
+
+Folded developer detail is concept-level by requirement: the overall design concept, the architecture of the main components, and hand-waving dataflow — enough to understand how the package works — plus source-map tables and links to code for exact detail. It never becomes an exhaustive catalog: no full API inventories, column lists, event-payload enumerations, or JSDoc restatement. The Dev Note is the only place allowed to hold partial ideas, scratches, and undecided directions; everything else, folds included, is polished current-state prose.
+
+Keep exhaustive generated types, schemas, or catalogs behind a compact entry paragraph and stable index. Split them by an existing domain owner when one lookup requires scanning unrelated groups.
+
+## Documentation hierarchy
+
+Use package-local READMEs for package contracts and keep them next to source. Organize cross-package Markdown under audience and learning intent instead of leaving unrelated pages flat at `docs/`.
+
+```text
+docs/
+  learn/
+    overview/
+    cordis/
+    practices/
+  user/
+  developer/
+    discussion/
+  scratch/
+  subsystems/
+```
+
+Treat this as a target map, not permission for an opportunistic mass move. Move one coherent topic at a time, repair every inbound link and website mapping atomically, preserve public routes or aliases, and keep `subsystems/` flat because its pages are logically parallel.
+
+`docs/scratch/` contains tracked, expiring discussion that must survive a handoff. Each scratch page names its owner, creation date, expiry, and promotion target. Local disposable notes remain ignored and uncommitted.
+
+## Small rule files
+
+Give an independently searchable rule, practice, example family, or decision one small file when it has its own owner, change cadence, inbound links, or validation. Group related files under a descriptive hierarchy such as `docs/developer/code-quality/`. Keep tightly coupled rules together when splitting would force readers to open several files to understand one obligation.
+
+An index page explains the folder in three to five sentences and links its direct children by purpose. It does not restate each child's rule.
+
+## Further Exploration
+
+Use this optional section for a newcomer who finished the page and wants adjacent understanding. Link three to seven directly related pages, order them from closest prerequisite to deeper exploration, and say in a short phrase what each adds. Do not turn it into a complete site index.
+
+## Dev Note ownership
+
+End authored pages with Dev Note, but keep it explicitly non-authoritative. Active hypotheses, compatibility concerns, rough alternatives, progress pointers, and unresolved questions may live there; stable behavior, required limitations, and accepted rationale belong in their ordinary owners.
+
+Dev Note may mirror or link task progress but must not become a second writable queue. When work closes, promote durable conclusions, move reusable rationale to an Agent Note, keep incident chronology in a postmortem, and delete resolved chatter. Git history preserves old iterations.
+
+## Dev Note
+
+The mandatory final section is intentionally the least polished part of an authored page, but it still has lifecycle discipline. A blank Dev Note should say `None.` rather than accumulate placeholder prose; generated and parser-owned formats may omit it through a named exception.

+# Page style
+
+## Summary
+
+Page-level style preferences that make DSH pages scannable and difficult to misread: a short Summary, controlled technical English, `-----` separators between major parts, `<details>` folds that keep section titles visible, and disciplined emphasis. The template is the `session-persistence-sqlite` README pair.
+
+## Table of Contents
+
+- [Short summary](#short-summary)
+- [Controlled technical English](#controlled-technical-english)
+- [Section separators](#section-separators)
+- [Foldable content sections](#foldable-content-sections)
+- [Emphasis discipline](#emphasis-discipline)
+- [Dev Note](#dev-note)
+
+## Short summary
+
+Open every authored page with a short `Summary`: three to five sentences in one paragraph stating what the subject is, why the reader cares, the operating model, and the most important boundary. The Table of Contents and the sections carry the detail; placement and section order live in [structure-hierarchy.md](structure-hierarchy.md).
+
+## Controlled technical English
+
+Use an [ASD-STE100](https://www.asd-ste100.org/)-inspired review pass for English prose that an agent, translator, or non-native reader must parse. This is a clarity discipline, not certified ASD-STE100 compliance. The repository does not reproduce or validate the standard's controlled dictionary.
+
+- Name the actor and action. Prefer active voice when the actor matters.
+- Use one stable term for each concept. Do not rotate synonyms for variety.
+- Prefer direct verbs. Replace nominalizations and ambiguous phrasal verbs when a precise verb exists.
+- Put one instruction in each sentence. Use a list for three or more steps or conditions.
+- Split semicolons and long clause chains. Keep each paragraph on one topic.
+- Remove unsupported quality adjectives and stacked hedges. Preserve every fact and degree of uncertainty from the source.
+
+Treat 20 words for an instruction and 25 words for a description as review prompts, not mechanical gates. Keep a longer sentence when a split would hide a condition or relationship. Never remove or strengthen `must`, `may`, `never`, timing, exceptions, numbers, or other contract terms to meet a length target. The [prose standard](../../dsh-prose-standard/SKILL.md) owns the complete-proposition rule.
+
+## Section separators
+
+Separate the major parts of a page with a `-----` horizontal rule on its own line, with a blank line before and after it. A rule directly after a paragraph would parse as a Setext heading, and a rule inside the final two H2 sections of a package README would break the Model Experience gate. The template separates: front matter → use section → folded developer section → Further Exploration → Model Experience.
+
+## Foldable content sections
+
+Fold developer-facing detail and the final Dev Note behind GitHub-native `<details>`/`<summary>` blocks. Keep the section title (H2 or H3) and its `<a id>` anchor visible; fold only the content under the title. Inside the block, put a blank line after `<summary>`, keep every Markdown line at column 0 (indented content becomes a code block), and close with `</details>` after a blank line. Headings, lists, tables, and links inside the fold parse normally and keep their anchors. The `session-persistence-sqlite` README pair demonstrates both folds: the implementation section and the Dev Note.
+
+In a package README, keep `## Model Experience` and `## Known Limitations and Deferred Work` as the final two H2 headings. Put the limitations anchor immediately after its H2 so it does not become part of the preceding Model Experience body. Place the final Dev Note under the limitations section as an anchored H3. A package that is explicitly exempt from the limitations section can use an H2 Dev Note.
+
+## Emphasis discipline
+
+Reserve bold for the clause that changes behavior or for the comparison that matters. In benchmark tables, bold the column headers and the best value in each row, as in the reference example.
+
+## Dev Note
+
+None.

-description: Use when publishing, updating, moving, or removing DeepSeek Harness documentation website pages; editing website/docs.ts mappings or navigation; diagnosing a page missing from the VitePress site; fixing projected documentation links; or running the docs:dev, docs:check, and doc-sync workflow after website-content changes.

-# Synchronizing the DeepSeek Harness Documentation Site
+## Summary
 
-Keep repository Markdown as the only editable content source. Treat the website as a tested projection: [website/docs.ts](../../../website/docs.ts) selects public pages, [scripts/project-doc-site.ts](../../../scripts/project-doc-site.ts) rewrites them into the disposable `website/.generated/` tree, and VitePress builds that tree. The build additionally emits a raw-Markdown twin of every route (page URL minus any trailing slash, plus `.md`; index routes also get a parent-level alias) and a root `llms.txt` index; both derive from the same manifest and projector, so publishing, moving, or removing a page updates them automatically and `docs:build` fails when one is missing.
+The documentation website is a tested projection of repository Markdown, never a second copy. [website/docs.ts](../../../../website/docs.ts) is the explicit public allowlist, [scripts/project-doc-site.ts](../../../../scripts/project-doc-site.ts) rewrites mapped sources into the disposable `website/.generated/` tree, and VitePress builds that tree. The build also emits a raw-Markdown twin of every route and a root `llms.txt` index from the same manifest. This reference owns the manifest fields, the projector's link rules, preview and validation commands, and the deployment boundary.
 
-Repository translations follow the sibling pairing contract: English `foo.md`, Chinese `foo.zh.md`, and `foo.i18n.yaml` live together. Never create `zh-CN/` or other locale directories for website content. The site route trees are independent of that source layout: `foo.zh.md` projects to the root route and `foo.md` projects to the matching `/en/` route.

+- **Installation guidance.** A plugin package mounts through `cordis.yml` rows.

 ## Source execution
 
 From the repository root, run `pnpm run build` separately after a fresh checkout and whenever artifacts need updating, then use `pnpm dsh <args...>`. The `package.json` script launches `apps/cli/src/bin.ts` with `node --import tsx/esm` without building and forwards every argument. Missing Typert host artifacts fail profile boot through module-resolution errors without a build instruction. Once those host artifacts exist, missing frontend or client-plugin bundles fail at startup with an instruction to run `pnpm run build`. The launcher does not check freshness, so existing stale bundles can run older browser code until rebuilt. The process inherits the launch environment; set `NODE_USE_ENV_PROXY=1` when a supporting Node version must honor `HTTP_PROXY` and `HTTPS_PROXY`. The installed form launches the built `apps/cli/lib/bin.js` without rebuilding the repository.

 请在仓库根目录中，于全新 checkout 之后及产物需要更新时单独运行 `pnpm run build`，然后使用 `pnpm dsh <args...>`。`package.json` 中的脚本不会构建，而是通过 `node --import tsx/esm` 启动 `apps/cli/src/bin.ts`，并转发所有参数。Typert Host 产物缺失时，profile 启动会因不含构建指引的模块解析错误而失败。这些 Host 产物存在后，如果前端或 Client plugin 组合包缺失，启动会失败并提示运行 `pnpm run build`。启动器不会检查产物是否为最新，因此已有的陈旧组合包可能继续运行旧版浏览器代码，直至重新构建。该进程会继承启动环境；当支持环境代理的 Node 版本必须遵循 `HTTP_PROXY` 和 `HTTPS_PROXY` 时，请设置 `NODE_USE_ENV_PROXY=1`。安装形式会直接启动构建后的 `apps/cli/lib/bin.js`，不会重新构建仓库。

 Remote and API Proxy share the Connection's `/api` route. The Client Remote calls `connection.rpc.call('/api', '<namespace>/<method>', { args }, signal)`; the HTTP carrier maps this to `POST /api/<namespace>/<method>`, with a payload containing only a named `args` object.
 
-The Connection performs the unified trust check for `/api` before the HTTP bridge, then dispatches inside the shared FetchHandler in interceptor order. The Typert Gateway claims only two-segment endpoints that have a strict descriptor or active SRC marker; unclaimed requests fall back to the existing API Proxy. The Connection owns transport, RPC ids, response envelopes, and request cancellation, while the Gateway owns only the Remote data protocol and business dispatch.

The Connection owns transport, RPC ids, response envelopes, and request cancellation, while the Gateway owns only the Remote data protocol and business dispatch. Replacing the Connection carrier does not require changes to Remote descriptors or the Client programming interface.
 
 For every call, the Gateway resolves the descriptor and live service from the current registries instead of caching business objects. It requires the fields in `args` to match the descriptor exactly, validates wire values with codecs, resolves objects or receivers through registered lookup or Context providers, invokes the service method targeted by the binding, and validates the return value. A missing provider, unknown identity, binding mismatch, missing or extra argument, schema failure, or missing method fails before entering or after leaving business code.
 
-The lookup provider's `register()` supplies both the stable declaration and the default resolver; `configure()` supplies a resolver owned by Host composition that may execute asynchronously and is scoped to an effect lifetime. Configuration may precede provider mounting; without a provider, invocation still fails with `lookup-unavailable`, and unloading the configuration restores the provider's default policy. API Remotes owns the standard `agentFor()` semantics for `agent` and `session`: it reuses a live Agent, automatically resumes ordinary cold sessions, deduplicates concurrent resumes, and rejects identities owned by subagent routing; the `session` lookup returns that Agent's Session. The Web API Proxy supplies its Agent defaults and scope setup, then consumes the same resolver for legacy methods. Resume failures and ownership fences pass through unchanged as existing RPC errors rather than being collapsed into the Gateway's `internal` error.

 Unloading a Client contribution removes its descriptors and concrete methods together, aborts its in-flight calls, and makes stale method handles retained by external code reject further calls. A strict endpoint withdrawn on the Host also does not degrade to SRC inference, preventing a hot unload from silently weakening validation.

+- A `GenerateOptions` field your provider cannot honor (e.g. a `stop` list on a provider without stop sequences): throw `LlmError(..., 'UNSUPPORTED_OPTION')` rather than silently dropping it.
 - If the provider requires response ids, signatures, or other native metadata on follow-up calls, emit the minimal lossless-JSON projection as `finish.replayState`. Validate it when rebuilding history. `LlmRuntime` passes it only when the historical provider route and target provider route are currently owned by the exact same adapter instance; your adapter decides whether same-model, cross-model, or cross-provider restoration is legal. Never infer native replay from provider/model names alone when state is absent.
 
 Provider-specific thinking-mode toggles remain in the adapter's Config. Exact model metadata uses one provider-neutral capability seam: implement `resolveModel()` with provider/model identity and optional `context` and `reasoning` fields, declare a configured `defaultEffort` only when one exists, and honor the resolver's optional `AbortSignal`. Reasoning efforts are ordered opaque ids mapped to provider requests by the adapter. Preserve the adapter's authoritative selectable list, including an adapter-defined `off` when supported, without exposing final wire spellings or clamping unsupported values; an id need not equal its wire representation.

Any structure the driver cannot verify remains an ordinary conflict; `pnpm run resolve-translation-pairing-conflicts` applies the same fail-closed operation to a merge that has already stopped, stages every safe pairing record, and exits unsuccessfully when other pairing conflicts remain. The [automatic pairing merges Agent Note](../../.agents/notes/implemented/process/2026-08-08-automatic-translation-pairing-merges.md) owns the mechanism and alternatives.

 - A request in the narrow interval after live detach but before the persistence catalog materializes the header can receive `session-not-found`; callers retry after retirement materialization.
 - Cold requests scan the complete Session snapshot catalog because persistence has no lookup-by-id metadata operation. One Session row also has no item-count or aggregate-byte cap; `maxNoteBytes` bounds only each note until a concrete consumer owns a row policy.

 `permission/preset` is durable, log-only user intent: it stays out of the model transcript (the knob events own the model-visible consequences through their consumers), and it exists so `current()` can preserve WHICH preset the user chose when two presets share a bundle; `effectivePermissionPreset(events)` folds the last one, and replay needs no catch-up state. The complete event declaration is in the [persistence log event catalog](../persistence-catalog.md); the method signatures are in the generated [service catalog](#ctxpermissionpresets--permissionpresetservice).

 When several events in one plugin-owned family assemble into one Web Client Conversation Node, every start, update, result, resource, or interruption event in that family carries or independently derives the same stable business id. This requirement applies to correlated Node families, not to every Session event; it lets the client group each event without guessing from adjacency or scanning history.

 The subagent seam lets an agent delegate work to a child agent. Like [bash](shell.md), it is **one optional capability**, not part of the agent loop, so its types live here rather than in [core.md](core.md). It differs from the other capability seams because **multiple provider implementations coexist** in one context, registered by name (`ctx.subagents`), while bash allows only one executor. Its registry follows the [LLM adapter registry](llm-streaming.md), not the single-service bash executor.

 subagent seam 让一个 agent（智能体）将工作委派给子 agent。与 [bash](shell.zh.md) 一样，它是**一项可选能力**，不属于 agent loop（智能体循环），因此其类型定义在此而非 [core.md](core.zh.md) 中。它不同于其他能力 seam，因为**同一上下文中可共存多个提供方实现**，并按名称注册（`ctx.subagents`），而 bash 只允许一个执行器。该注册表遵循 [LLM（大语言模型）适配器注册表](llm-streaming.zh.md)，而非单服务的 bash 执行器。

 Sessions get their cwd at create time from whoever creates them, not from this registry — the API gateway resolves a new session's cwd from the chosen workspace's `path` (falling back to an explicit or default cwd), creates the session so the cwd lands in its immutable [`SessionHeader`](persistence.md#sessionheader--metadata-beside-the-log), then calls `attachSession`, which re-validates that stored header cwd against the workspace path. On the first successful start, the registry bootstraps history from persisted headers alone (`id`, `cwd`, `createdAt` — never event bodies), grouping sessions with a valid canonical cwd into per-directory workspaces, newest first; the initialized marker is written last so an interrupted bootstrap resumes safely. The bootstrap is one-time: cwd-less legacy sessions stay Ungrouped, and sessions created afterwards join a workspace only through `attachSession`.

 ## Tiers
 
 - **Unit** (`pnpm run test`): vitest over package and example specs under their `tests/**` directories plus repository script specs under `scripts/**/*.spec.ts`; tests stay with the code area they exercise. Every registry gets an HMR-safety test (dispose the contributing fiber, assert cleanup). Prefer edge cases, error paths, event ordering, concurrency races, and permanent tests for contract regressions (see `packages/core/agent-loop/tests/contract-regressions.spec.ts`).
-- **Coverage gate** (`pnpm run test:coverage`): the gating run, per-file 100% on `packages/*/*/src`.

 - **Real-API e2e** (`pnpm run test:e2e`): with-key tests against live provider APIs — the DeepSeek model plus provider-specific smokes that gate on their own keys (`EXA_API_KEY`, `PERPLEXITY_API_KEY`, …); each suite self-skips without its key so keyless CI stays green ([real-API e2e Agent Note](../.agents/notes/implemented/testing/2026-06-19-real-api-e2e-ci.md)).
 - **Owner-local expected output** (`pnpm run test:expected`): keyless assembled CLI/process expectations without a recorded-session round trip. Drivers use `*.expected.e2e.ts` beside `tests/expected/`; CI runs built exports. Package/script expectations use `test`, while browser expectations use `test:web`.
 - **Snapshot** (`pnpm run test:snapshot`): a top-level scenario's recorded `session.jsonl` supplies user input and model replay, then serves as the expected persisted result. Process scenarios start through `dsh`: headless owns one-shot behavior, the SDK owns persistent control, ACP owns automation-protocol behavior, and Web retains browser/ARIA evidence beside the same session. `snapshot.yml` declares the profile, composition/header class, recording policy, exceptional replay or input metadata, and workspace facts. Typed tokens preserve parent/child identity relationships; only header pins own prompt/schema sidecars. A mutating scenario independently compares the complete `workspace.expected/` tree, which record and refresh never rewrite. Use `test:snapshot:record` when a model transcript changes and `test:snapshot:refresh` when replay input remains valid; review every resulting diff.
 - **Web browser snapshot** (`pnpm run test:web`; required Linux PR gate): Chromium compares session-driven output under `snapshots/web/` and UI-only output under `apps/web/tests/expected/`. CI forces read-only `DSH_SNAPSHOT=replay`, never writing expected outputs; record/refresh stay local and every diff is reviewed ([web e2e lane](../.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.md), [CI gate decision](../.agents/notes/implemented/testing/2026-07-30-web-browser-snapshot-ci-gate.md)). `test:web` [builds first](../.agents/notes/implemented/bug-fix/2026-07-28-themed-scrollbars-and-reserved-gutter.md) for plugin CSS.

 ## Test the real entry path
 
 - Product-visible plugins require a non-unit REAL-composition test.

+description: "The DeepSeek Harness package workspace: how the npm packages under packages/ are grouped, what each group owns, and the conventions that bind them."
+kind: "package-group"
+---

 # Packages
 
 English | [中文](README.zh.md)
 
-npm scope: `@deepseek-ai/dsh-*`; Cordis `Service` subclasses and function plugins contribute through `ctx.effect()`, `ctx.on()`, or `ctx.waterfall()`. Rules: [package](AGENTS.md), [root](../AGENTS.md#conventions).
+## Summary
 
-## Hierarchy
+The harness is assembled from npm packages under `packages/`, grouped by capability family: sessions and the agent loop, model-facing tools, shell and filesystem execution, web access, subagents, and the rest. Use this page as the top-level map: find the owning group, then open its README for the package list. Every package is scoped `@deepseek-ai/dsh-*` and lives in exactly one group; each group README is the authoritative package map for its family.
 
-Groups hold `packages/<group>/<pkg>/`; names stay `@deepseek-ai/dsh-<pkg>`. **Group READMEs own package/ctx-key maps.**

+-----
+
+<a id="release-expectations"></a>
+## Release expectations
+
+Most groups are product — stable API. The exceptions: `e2b/` is a POC, `experimental/` is unreleased, and `examples/`, `test-support/`, `runtime-diagnostics/`, and `util/` are support with lower compatibility expectations.
+
+-----
+
+<a id="dependencies"></a>
 ## Dependencies
 
 The dependency graph is generated: [docs/module-graph.md](../docs/module-graph.md) (`pnpm run gen-module-graph`, freshness-gated in CI).
 
 **Extension plugins depend on Service Definitions, never concrete providers.** `dsh-agent-loop` is swappable; UI, hook, and tool plugins use `dsh-agent`. Composition bundles, including `dsh-agent-spine-demo`, may depend on spine plugins. Capabilities separate Service Definition / Service Provider / Consumer roles when they evolve independently; see [capability seams](../.agents/notes/implemented/architecture/2026-06-13-capability-seams.md).
 
-Package READMEs cover purpose, APIs, extension points, and [Model Experience](../docs/cookbook/adding-a-package.md#4-write-the-package-readme) unless on the model-agnostic [omission allowlist](../scripts/verify-package-readme-model-experience.ts). They also carry `## Known Limitations and Deferred Work` or use its [allowlist](../scripts/verify-package-readme-limitations.ts).

+## Package README contracts
+
+Every package README covers purpose, configuration, extension points, and [Model Experience](../docs/cookbook/adding-a-package.md#4-write-the-package-readme) unless the model-agnostic [omission allowlist](../scripts/verify-package-readme-model-experience.ts) exempts it. It also carries `## Known Limitations and Deferred Work` or uses its [allowlist](../scripts/verify-package-readme-limitations.ts). Package conventions — exports, service access, invariants, tests — live in [packages/AGENTS.md](AGENTS.md).

 # 包
 
 [English](README.md) | 中文
 
-npm scope 为 `@deepseek-ai/dsh-*`；Cordis `Service` 子类和函数插件通过 `ctx.effect()`、`ctx.on()` 或 `ctx.waterfall()` 注册。规则见[包](AGENTS.md)与[根规则](../AGENTS.md#conventions)。
+## 概述
 
-## 层级结构
+harness 由 `packages/` 下的 npm 包组装而成，按能力系列分组：会话与 agent 循环、面向模型的工具、shell 与文件系统执行、Web 访问、subagent 等等。把本页当作顶层地图使用：先找到拥有某能力的组，再打开其 README 查看包列表。每个包都以 `@deepseek-ai/dsh-*` 为作用域、只属于一个组；每个组的 README 都是该能力系列的权威包映射。
 
-包按组置于 `packages/<group>/<pkg>/`；包名仍为 `@deepseek-ai/dsh-<pkg>`。**组 README 负责包／ctx 键映射。**

 # acp/ — Agent Client Protocol automation
 
 English | [中文](README.zh.md)
 
-The ACP group exposes harness agents to programmatic clients over the Agent Client Protocol. It is an interoperability transport, not a presentation or human-interaction layer; the matching out-of-process subagent *client* lives in [`subagent/subagent-acp`](../subagent/subagent-acp/README.md) because it implements the subagent provider interface.
+## Summary
+
+The acp group provides one package: a server that lets programs and automation run persistent DeepSeek Harness agents over the standard Agent Client Protocol. A client can create, list, resume, and close sessions; attach standard MCP servers; select model options; send text and image prompts; receive semantic updates; answer permission prompts; and cancel work without a human in the loop. The matching client for spawning such a server from another harness lives in `subagent/subagent-acp`. This page maps the group; the package README owns the per-package contract.

 # @deepseek-ai/dsh-acp
 
 English | [中文](README.zh.md)
 
-Automation-only [Agent Client Protocol](https://agentclientprotocol.com) v1 server over JSON-RPC stdio. Trusted programmatic clients can discover standard configuration, create or resume persistent harness Agents, attach MCP servers, prompt and cancel work, receive semantic execution updates, and close one session without affecting others.
+## Summary
 
-This package is not a UI integration. It emits standard ACP semantic data, never DSH presentation cards, terminal views, diffs, locations, plans, titles, todos, custom methods, custom capability flags, or DSH-specific `_meta`. Client `_meta` is accepted as protocol metadata and has no private DSH meaning.
+`dsh-acp` lets trusted programs drive persistent DeepSeek Harness agents over the standard [Agent Client Protocol](https://agentclientprotocol.com): create or resume sessions, list resumable sessions, attach standard MCP servers, select a model and reasoning effort, prompt or cancel work, receive semantic execution updates, and close one session without affecting others. It is built for automation — out-of-process subagents, test runners, and scripted controllers — rather than the DSH user interface: it emits standard ACP messages, thoughts, generic tool lifecycle, configuration, and context usage, never private DSH presentation data or methods. Session persistence enables list, resume, and close across process restarts, while deletion, fork, transcript replay, additional directories, and interactive UI surfaces remain unsupported. The repository's own ACP client is `dsh-subagent-acp`, and `pnpm dsh --profile acp` starts a ready-to-use server. Setup and usage come first; the implementation details live in a collapsible developer section below.
 
-## Plugin
+## Table of Contents
 
-`apply(ctx, config)` opens an ACP SDK agent app on stdin/stdout and drives `ctx.agents`. Stdout is reserved for protocol frames. Complete lifecycle support requires `ctx.sessionPersistence`.

+-----
+
+<a id="use-this-package"></a>
+## Use this package
+
+Use this package when a script, test runner, or another harness needs to run agent work end to end through a standard automation protocol. The common path is: start the server, create or resume a session, optionally mount MCP servers and select model options, send a prompt, consume semantic updates, and close the session.
+
+### When to choose it
+
+Choose it when automation should own the interaction: an out-of-process subagent, test runner, or scripted controller that manages persistent sessions, tools, model selection, and permissions. Avoid it when a human needs DSH-specific presentation cards, plans, titles, todos, terminal views, or elicitation; this server intentionally exposes only the standard ACP v1 surface.
+
+### Minimal configuration
+
+Every session the server creates uses the provider and model configured here. Both fields are optional so another agent or request listener can supply them; the runnable demo composition sets both. Stdout carries only protocol traffic, so keep logging off it.
+
+```yaml
+- name: '@deepseek-ai/dsh-acp'
+  config:
+    provider: deepseek-official
+    model: deepseek-v4-pro
+```
+
+| Field | Default | Meaning |
 |---|---|---|
-| `provider` | — | Initial provider route for each created or resumed Agent. |
-| `model` | — | Initial exact model for each created or resumed Agent. |
-| `sessionListPageSize` | `100` | Positive maximum number of summaries in one `session/list` page. |
+| `provider` | — | Provider route for every session's agent |
+| `model` | — | Model for every session's agent |
+| `sessionListPageSize` | `100` | Maximum summaries returned in one `session/list` page |
 
-`provider` and `model` may be omitted when another Agent request listener supplies the initial route. The runnable ACP composition requires both.
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-acp) is the exhaustive source for every accepted field and its JSDoc.
 
-## Standard ACP v1 surface
+### Start a server
 
-| Method or notification | Behavior |
+`pnpm dsh --profile acp` starts the shipped stdio server. The `acp` profile mounts session persistence, so clients can list, resume, and close persistent sessions. [`@deepseek-ai/dsh-subagent-acp`](../../subagent/subagent-acp/README.md) starts the same profile for out-of-process delegation.
+
+<a id="protocol-contract"></a><a id="standard-acp-v1-surface"></a>
+### Protocol contract
+
+One connection can run several sessions at once, each independent. The calls a client makes:
+
+| Call | What you get |
 |---|---|
-| `initialize` | Negotiates stable ACP v1. Advertises standard `session/list`, `session/resume`, `session/close`, and Streamable HTTP MCP support. Image prompts are advertised only when a durable attachment store and the configured exact route support them. |
-| `authenticate` | No-op because the server advertises no authentication methods. |
-| `session/new` | Creates one Agent with an absolute primary `cwd`, validates and mounts standard stdio or HTTP MCP servers before publishing the Agent, explicitly materializes its durable header, and returns the complete configuration-option state. |
-| `session/list` | Returns deterministic newest-first pages of persisted, resumable top-level sessions. Summaries contain only `sessionId` and absolute `cwd`; cursors are opaque keyset tokens. An optional absolute `cwd` filter uses physical-directory identity when paths exist. Active sessions and subagent/fork descendants are omitted. |
-| `session/resume` | Rejects an active id, verifies the persisted canonical workspace before Agent composition, restores the log without replaying it to the client, mounts the request's MCP servers, and returns the complete configuration-option state. |
-| `session/close` | Cancels active work, drains ordered updates and continuable descendants, flushes persistence, and disposes only that Agent scope. Persisted state remains available to `session/list` and `session/resume`. |
-| `session/set_config_option` | Sets an advertised `model` or `reasoning_effort` value and returns the complete resulting state. Invalid ids and values reject as invalid params. |
-| `session/prompt` | Admits ordered text, resource links, and supported images; permits one in-flight prompt per session; and settles only after Agent idle plus ordered update delivery. |
-| `session/cancel` | Cancels the addressed prompt admission or turn through its prompt-owned cancellation path. With no ACP prompt in flight it cancels autonomous work; unknown ids are no-ops. |
-| `$/cancel_request` | Cancellation of a `session/prompt` JSON-RPC request uses the same prompt-owned path as `session/cancel`. |
-| `session/update` | Emits committed message, thought, generic tool lifecycle, configuration, and context-usage updates described below. |
-| `session/request_permission` | Requests one standard one-shot allow or reject decision after the referenced `tool_call` notification has been delivered. |
+| `initialize` | Stable ACP v1 plus `session/list`, `session/resume`, `session/close`, and Streamable HTTP MCP support; image prompts only when the durable attachment store and configured exact route support them. |
+| `authenticate` | Immediate success; the server requires no authentication. |
+| `session/new` | A fresh persistent agent whose absolute workspace and stdio or HTTP MCP servers are validated before publication, plus its complete configuration-option state. |
+| `session/list` | Deterministic newest-first pages of persisted, resumable root sessions; an optional absolute `cwd` filter uses physical-directory identity where possible. |
+| `session/resume` | A persisted inactive session whose canonical workspace is verified before composition; its log is restored without replaying old updates. |
+| `session/close` | Quiescent cancellation, update draining, descendant disposal, persistence flush, and disposal of only the addressed Agent scope. |
+| `session/set_config_option` | A serialized update to the advertised `model` or `reasoning_effort`, returning the complete resulting state. |
+| `session/prompt` | Ordered text, resource links, and supported images, one prompt at a time per session; settlement follows Agent idle and ordered update delivery. |
+| `session/cancel` / `$/cancel_request` | The prompt-owned cancellation path; without an ACP prompt in flight it cancels autonomous work, while unknown session ids are no-ops. |
+| `session/update` | Committed assistant messages and thoughts, generic tool lifecycle, configuration changes, and context usage, serialized per session. |
+| `session/request_permission` | A permission prompt with one-shot allow/reject choices; your client can answer automatically. |
 
-Unsupported surfaces are omitted from capabilities or reject when addressed: `session/load`, `session/delete`, `session/fork`, additional directories, SSE and ACP-transport MCP, modes, commands, plans, terminals, client filesystem operations, and elicitation.
+Session configuration offers opaque provider/model choices from the live LLM service catalog and a `reasoning_effort` selector when the exact model declares one. A prompt snapshots that selection before asynchronous image admission and pins it across every model step in that turn; a concurrent option change applies to the next turn. ACP clients are trusted controllers: stdio MCP entries authorize their absolute commands and environment, HTTP entries authorize their absolute HTTP(S) URLs and headers, and any initial connection or discovery failure rolls back the unpublished Agent. Unsupported surfaces are omitted or reject: `session/load`, deletion, fork, additional directories, SSE or ACP-transport MCP, modes, commands, plans, terminals, client filesystem operations, and elicitation.
 
-## Session configuration
+-----
 
-Every new or resumed session returns standard select options:
+<a id="understand-the-implementation"></a>
+## Understand the implementation
 
-- `model` groups choices by provider from the advisory LLM catalog. Values are opaque strings carrying the exact provider/model pair; clients must return them unchanged.
-- `reasoning_effort` is derived from the selected exact model and is omitted when that model does not declare reasoning choices. When the adapter exposes choices but preserves the provider's own default, a `Provider default` choice represents omitting an explicit effort.
+<details>
+<summary>Implementation internals — click to expand</summary>
 
-The ACP plugin's `provider` and `model` config establish the initial selection. Adapter topology changes emit `config_option_update` with the complete current state. Mutations are serialized per session.
+This section explains how the server realizes the behavior above and points at the code that implements it; the observable behavior is fully covered in [Use this package](#use-this-package).
 
-An accepted prompt snapshots the selected route before asynchronous image admission. Its per-session module associates that snapshot with the identified inbox message until claim, then pins the same provider, model, and reasoning effort across image validation, prompt variables, and every model step in that turn. A concurrent option change applies to the next ACP turn.
+### Design philosophy
 
-## MCP trust and isolation
+The server is an automation transport with an intentionally standard public protocol. Three commitments shape it:
 
-ACP clients are trusted automation controllers. A stdio declaration authorizes DSH to execute its absolute command in the session `cwd` with the supplied arguments and environment entries. An HTTP declaration authorizes requests to its absolute HTTP(S) URL with the supplied headers. DSH does not reinterpret client metadata or add private cwd, timeout, or transport fields.
+- **Standard semantic updates only.** The wire carries committed messages and thoughts, generic tool lifecycle, configuration, and context usage; raw provider deltas, retry attempts, DSH presentation data, and unsupported content stay off the wire.
+- **Truthful capability and configuration state.** `initialize` advertises only mounted support, topology changes publish complete configuration options, and a prompt pins the exact route it admitted.
+- **Quiescence before settlement.** Prompt and close operations settle only after their owned admission, Agent activity, ordered updates, descendants, persistence, and disposal have reached the required terminal state.
 
-Server names are validated and converted to stable DSH MCP namespaces; duplicate normalized names reject before Agent publication. Environment names/values and HTTP headers are validated, including case-insensitive duplicate headers. Standard stdio and Streamable HTTP clients use `dsh-mcp-client`'s existing tool-call timeout and reconnect defaults. Initial connection and tool discovery must succeed, so any failure rolls back the unpublished Agent.
+The decision history lives in the [ACP as an automation-only protocol note](../../../.agents/notes/implemented/simplification/2026-07-23-acp-automation-only-protocol.md) and the [multi-session note](../../../.agents/notes/implemented/feature/2026-06-14-acp-multi-session.md).
 
-Each Agent scope owns its MCP registrations and connections. The same server namespace may therefore exist in independent ACP sessions, while a duplicate inside one session still fails. Session close, connection loss, and plugin disposal release the scoped tools and transports.
+### Source map
 
-## Semantic updates
-
-Per-session delivery is serialized and drained before prompt completion:
-
-| Durable DSH fact | Standard ACP update |
+| File | Role |
 |---|---|
-| Committed assistant text or image | `agent_message_chunk` with the durable message id |
-| Committed reasoning | `agent_thought_chunk` with the durable message id |
-| Durable tool call | `tool_call` with the DSH call id, canonical DSH tool name as `title`, generic `other` kind, and parsed input when valid JSON |
-| Durable tool result | `tool_call_update` with the same call id, completed/failed status, and standard content blocks |
-| Known context capacity plus measured context pressure | `usage_update` |
-| LLM adapter topology change | `config_option_update` with all options |
+| [`src/index.ts`](src/index.ts) | Plugin entry: `Config` schema, `AgentSideConnection` wiring, per-session records, admission and settlement, teardown |
+| [`src/content.ts`](src/content.ts) | Wire-content admission and projection: image validation, route recheck, prompt reconstruction, assistant block conversion |
+| [`src/codec.ts`](src/codec.ts) | Pure turn-ending to ACP `stopReason` mapping |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; this transport owns no durable package-local event stream) |
 
-Raw model deltas, retry attempts, presentation data, and unsupported core content never enter the ACP wire. Committed images are re-read and integrity-verified before inline base64 delivery. A missing or corrupt committed image fails the correlated prompt instead of producing a placeholder.
+### Admission and prompt settlement
 
-## Lifecycle and outcomes
+Each session permits one in-flight prompt. Admission validates the whole prompt batch, snapshots the selected route, rechecks the exact Agent identity and image capability, persists image attachments, and only then queues the user message — a cancellation that wins admission never enqueues a late turn. Once queued, the session module associates the snapshot with the inbox message until claim and pins the same provider, model, and reasoning effort across prompt variables and every model step in that turn. Per-session update delivery is serialized; committed images are re-read and integrity-verified, so a missing or corrupt image fails the correlated prompt instead of emitting a placeholder. Settlement precedence is explicit cancellation, committed-output failure, interval-wide Agent failure, then the correlated turn ending.
 
-One connection may own several independent sessions. Exact Agent identity guards event and permission routing. Each per-session module owns its Agent handle, MCP mounts, future and turn-pinned model selections, prompt slot, update chain, and memoized close operation.
+### Teardown and connection ownership
 
-Explicit close, connection loss, and plugin disposal use the same quiescent teardown. Teardown stops new work, cancels prompt admission and Agent activity, drains committed updates, disposes continuable descendants child-first, flushes the session, and releases every Agent scope. Failures are reported only after all owned teardown work settles; other frontends sharing the Context are untouched.
+Each session module owns its Agent handle, MCP mounts, future and turn-pinned model selections, prompt slot, update chain, and memoized close operation. Explicit close, client disconnect, and Cordis disposal use the same quiescent teardown: stop new work, cancel prompt admission and Agent activity, drain committed updates, dispose continuable descendants child-first, flush persistence, and release the owned Agent scope. A session close leaves persisted state available for list and resume, and other sessions or frontends sharing the Context remain untouched.
 
-Prompt settlement precedence is explicit cancellation, committed-output failure, interval-wide Agent failure, then the correlated turn ending. Standard outcomes include `end_turn`, `max_tokens`, and `cancelled`; correlated model failures become standard JSON-RPC errors. No additional DSH result object is returned.
+</details>
 
-## Running
+-----
 
-`pnpm --dir /path/to/deepseek-harness dsh --profile acp` boots the repository's automation server profile.

 # @deepseek-ai/dsh-acp
 
 [English](README.md) | 中文
 
-通过 JSON-RPC stdio 提供的仅面向自动化的 [Agent Client Protocol](https://agentclientprotocol.com) v1 服务器。受信任的程序化客户端可以发现标准配置、创建或恢复持久化的 harness Agent、挂载 MCP 服务器、提示和取消工作、接收语义执行更新，并在不影响其他会话的情况下关闭单个会话。
+## 概述
 
-此包不是 UI 集成。它只发出标准 ACP 语义数据，绝不发出 DSH 展示卡片、终端视图、diff、位置、计划、标题、todo、自定义方法、自定义能力标记或 DSH 专用 `_meta`。客户端 `_meta` 仅作为协议元数据接收，不具有 DSH 私有含义。
+`dsh-acp` 让受信程序可以通过标准 [Agent Client Protocol（ACP）](https://agentclientprotocol.com) 驱动持久 DeepSeek Harness agent：创建或恢复会话、列出可恢复会话、挂载标准 MCP 服务器、选择模型与推理强度、发送或取消工作、接收语义执行更新，并关闭一个会话而不影响其他会话。它是为自动化而生的——进程外 subagent、测试运行器与脚本化控制器——而不是 DSH 用户界面：它发送标准 ACP 消息、thought、通用工具生命周期、配置与上下文用量，绝不发送 DSH 私有呈现数据或方法。会话持久化支持跨进程重启的列出、恢复与关闭，而删除、fork、转录回放、附加目录与交互式 UI 界面仍不支持。仓库自带的 ACP 客户端是 `dsh-subagent-acp`，`pnpm dsh --profile acp` 会启动一个开箱即用的服务器。设置与用法在前；实现细节放在下方可折叠的开发者章节中。
 
-## 插件
+## 目录
 
-`apply(ctx, config)` 在 stdin/stdout 上打开 ACP SDK agent app，并驱动 `ctx.agents`。Stdout 专用于协议帧。完整生命周期支持要求挂载 `ctx.sessionPersistence`。

-| 配置 | 默认值 | 含义 |
+-----
+
+<a id="use-this-package"></a>
+## 使用本包
+
+当脚本、测试运行器或另一个 harness 需要通过标准自动化协议端到端运行 agent 工作时，使用本包。常用路径是：启动服务器、创建或恢复会话、按需挂载 MCP 服务器并选择模型选项、发送提示词、消费语义更新，再关闭会话。
+
+### 何时选择
+
+当自动化应拥有交互时选择它：管理持久会话、工具、模型选择与权限的进程外 subagent、测试运行器或脚本化控制器。当人类需要 DSH 专用呈现卡片、计划、标题、todo、终端视图或 elicitation 时请避开；本服务器刻意只提供标准 ACP v1 界面。
+
+### 最小配置
+
+服务器创建的每个会话都使用此处配置的提供方与模型。两个字段都是可选的，以便由另一个 agent/request 监听器提供；可运行的演示组合会同时设置两者。Stdout 只承载协议流量，因此请让日志远离它。
+
+```yaml
+- name: '@deepseek-ai/dsh-acp'
+  config:
+    provider: deepseek-official
+    model: deepseek-v4-pro
+```
+
+| 字段 | 默认值 | 含义 |
 |---|---|---|
-| `provider` | 无 | 每个新建或恢复 Agent 的初始提供方路由。 |
-| `model` | 无 | 每个新建或恢复 Agent 的初始确切模型。 |
-| `sessionListPageSize` | `100` | 单个 `session/list` 页面返回的摘要数量上限，必须为正数。 |
+| `provider` | — | 每个会话 agent 的提供方路由 |
+| `model` | — | 每个会话 agent 的模型 |
+| `sessionListPageSize` | `100` | 单页 `session/list` 返回的最大摘要数量 |
 
-当另一个 Agent 请求监听器提供初始路由时，可以省略 `provider` 和 `model`。可运行 ACP 组合同时要求两者。
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-acp)是每个受支持字段及其 JSDoc 的穷尽式真源。
 
-<a id="standard-acp-v1-surface"></a>
+### 启动服务器
 
-## 标准 ACP v1 接口
+`pnpm dsh --profile acp` 会启动随附的 stdio 服务器。`acp` profile 会挂载会话持久化，因此客户端可以列出、恢复和关闭持久会话。[`@deepseek-ai/dsh-subagent-acp`](../../subagent/subagent-acp/README.zh.md) 会启动同一 profile 来执行进程外委派。

+### 协议约定
+
+一个连接可以同时运行多个会话，彼此独立。客户端发出的调用如下：
+
+| 调用 | 你会得到什么 |
 |---|---|
-| `initialize` | 协商稳定 ACP v1。公布标准 `session/list`、`session/resume`、`session/close` 和 Streamable HTTP MCP 支持。只有持久附件存储和配置的确切路由都支持图片时，才公布图片提示词能力。 |
-| `authenticate` | 空操作，因为服务器不公布身份验证方法。 |
-| `session/new` | 使用绝对主 `cwd` 创建一个 Agent；在公布 Agent 前校验并挂载标准 stdio 或 HTTP MCP 服务器；显式实体化其持久 header；返回完整配置选项状态。 |
-| `session/list` | 按创建时间从新到旧，确定性分页返回已持久化且可恢复的顶层会话。摘要只包含 `sessionId` 和绝对 `cwd`；cursor 是不透明的 keyset token。可选绝对 `cwd` 过滤器会在路径存在时比较物理目录身份。活动会话以及 subagent／fork 后代不会出现。 |
-| `session/resume` | 拒绝活动 id；在组合 Agent 前校验持久化会话的规范工作区；恢复日志但不向客户端重放；挂载该请求的 MCP 服务器；返回完整配置选项状态。 |
-| `session/close` | 取消活动工作、drain 有序更新和可继续后代、flush 持久化，并只释放该 Agent scope。持久化状态仍可供 `session/list` 和 `session/resume` 使用。 |
-| `session/set_config_option` | 设置已公布的 `model` 或 `reasoning_effort` 值，并返回完整结果状态。无效 id 或值以 invalid params 拒绝。 |
-| `session/prompt` | 准入有序文本、资源链接和受支持图片；每个会话只允许一个进行中的提示词；只在 Agent 空闲且有序更新交付完成后结算。 |
-| `session/cancel` | 通过提示词自有取消路径取消指定的准入或轮次。没有 ACP 提示词进行时取消自主工作；未知 id 为空操作。 |
-| `$/cancel_request` | 取消 `session/prompt` JSON-RPC 请求时，使用与 `session/cancel` 相同的提示词自有路径。 |
-| `session/update` | 发出下文所述的已提交消息、思考、通用工具生命周期、配置和上下文用量更新。 |
-| `session/request_permission` | 在引用的 `tool_call` 通知交付后，请求一次标准的一次性允许或拒绝决定。 |
+| `initialize` | 稳定 ACP v1，以及 `session/list`、`session/resume`、`session/close` 与 Streamable HTTP MCP 支持；图片提示词只在持久附件存储和配置的确切路由支持时公布。 |
+| `authenticate` | 立即成功；服务器不需要身份验证。 |
+| `session/new` | 全新持久 agent；其绝对工作区与 stdio 或 HTTP MCP 服务器会在发布前通过校验，并返回完整配置选项状态。 |
+| `session/list` | 按确定的新到旧顺序分页返回已持久、可恢复的根会话；可选绝对 `cwd` 筛选会尽可能使用物理目录标识。 |
+| `session/resume` | 恢复一个已持久且非活跃的会话；组合前校验其规范工作区，并恢复日志但不回放旧更新。 |
+| `session/close` | 停稳式取消、更新 drain、后代释放、持久化 flush，并且只释放指定 Agent 作用域。 |
+| `session/set_config_option` | 串行更新公布的 `model` 或 `reasoning_effort`，并返回完整结果状态。 |
+| `session/prompt` | 有序文本、资源链接与受支持图片，每个会话一次一个提示词；Agent 空闲且有序更新交付后才结算。 |
+| `session/cancel` / `$/cancel_request` | 提示词所拥有的取消路径；没有进行中的 ACP 提示词时取消自主工作，未知会话 id 则为空操作。 |
+| `session/update` | 已提交 assistant 消息与 thought、通用工具生命周期、配置变化与上下文用量，按会话串行交付。 |
+| `session/request_permission` | 带一次性允许／拒绝选项的权限提示；你的客户端可以自动回答。 |
 
-未支持的接口不会出现在能力中，或在被调用时拒绝：`session/load`、`session/delete`、`session/fork`、附加目录、SSE 和 ACP 传输 MCP、模式、命令、计划、终端、客户端文件系统操作以及 elicitation。
+会话配置从实时 LLM 服务目录提供不透明的提供方／模型选项，并在确切模型声明推理选项时提供 `reasoning_effort`。提示词会在异步图片准入前快照该选择，并在该轮的每个模型步骤中固定它；并发选项变更从下一轮开始生效。ACP 客户端是受信控制器：stdio MCP 条目授权其绝对命令与环境，HTTP 条目授权其绝对 HTTP(S) URL 与 header；初始连接或发现失败会回滚尚未发布的 Agent。不支持的界面会被省略或拒绝：`session/load`、删除、fork、附加目录、SSE 或 ACP 传输 MCP、mode、命令、计划、终端、客户端文件系统操作与 elicitation。

-ACP 插件的 `provider` 和 `model` 配置建立初始选择。Adapter 拓扑变化会发送包含完整当前状态的 `config_option_update`。每个会话会串行处理配置变更。
+本节解释服务器如何实现上述行为，并指出实现它的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
 
-已接受的提示词会在异步图片准入前快照所选路由。Per-session 模块会把该快照与已识别 inbox 消息关联到 claim 时刻，再把同一提供方、模型和 reasoning effort 固定到图片校验、提示词变量以及该轮次中的每个模型步骤。并发配置变更从下一个 ACP 轮次开始生效。
+### 设计理念
 
-## MCP 信任与隔离
+服务器是刻意采用标准公开协议的自动化传输。三项承诺塑造了它：
 
-ACP 客户端是受信任的自动化控制器。stdio 声明授权 DSH 在会话 `cwd` 中执行其绝对命令，并使用所给参数和环境项。HTTP 声明授权向其绝对 HTTP(S) URL 发送带所给 header 的请求。DSH 不重新解释客户端元数据，也不增加私有 cwd、超时或传输字段。
+- **只发送标准语义更新。** 协议承载已提交消息与 thought、通用工具生命周期、配置与上下文用量；原始提供方增量、重试尝试、DSH 呈现数据与不受支持内容不会进入协议。
+- **诚实的能力与配置状态。** `initialize` 只公布已挂载支持，拓扑变化会发布完整配置选项，提示词则固定其准入时的确切路由。
+- **停稳后才结算。** 提示词与关闭操作只在其拥有的准入、Agent 活动、有序更新、后代、持久化与释放达到所需终态后才结算。
 
-服务器名称会经过校验并转换为稳定的 DSH MCP namespace；重复的规范化名称会在 Agent 公布前拒绝。环境变量名／值和 HTTP header 会被校验，其中 header 重复检查不区分大小写。标准 stdio 与 Streamable HTTP 客户端使用 `dsh-mcp-client` 现有的工具调用超时和重连默认值。初始连接和工具发现必须成功，因此任何失败都会回滚尚未公布的 Agent。
+决策历史记录在 [ACP 作为仅面向自动化的协议笔记](../../../.agents/notes/implemented/simplification/2026-07-23-acp-automation-only-protocol.zh.md) 与[多会话笔记](../../../.agents/notes/implemented/feature/2026-06-14-acp-multi-session.zh.md) 中。
 
-每个 Agent scope 拥有自己的 MCP 注册和连接。因此，独立 ACP 会话可以使用相同服务器 namespace，而同一会话内的重复仍会失败。会话关闭、连接丢失和插件释放都会移除 scoped 工具和传输。

+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；本传输不拥有持久包内事件流） |
 
-原始模型 delta、重试尝试、展示数据和不受支持的核心内容绝不会进入 ACP wire。已提交图片在以内联 base64 交付前会重新读取并校验完整性。已提交图片缺失或损坏会使关联提示词失败，而不会产生占位符。

-## 生命周期与结果
+每个会话只允许一个正在处理的提示词。准入先校验整个提示词批次、快照所选路由、重新检查 Agent 是否为同一对象与图片能力、持久化图片附件，然后才把用户消息入队——赢得准入的取消绝不会入队迟到的轮次。入队后，会话模块把该快照与 inbox 消息关联到认领时刻，并在提示词变量与该轮的每个模型步骤中固定相同的提供方、模型与推理强度。按会话更新会串行交付；已提交图片会重新读取并验证完整性，因此图片缺失或损坏会让关联提示词失败，而不是发出占位符。结算优先级依次为显式取消、已提交输出失败、区间内 Agent 失败、关联轮次结束。

 # api/ — Remote API layers
 
 English | [中文](README.zh.md)
 
-The application-facing Remote stack. `remotes` owns BFF policy and the selected business API, while `gateway` implements the Typert unary RPC endpoints shared by Host and Client environments.
+## Summary
+
+The `api/` group provides the application's Remote layer: a Client environment can call the business capabilities running on the Host — manage goals, run commands, list the plugin inventory, discover file and session references — as typed method calls, and receive the results or forwarded Host events. `remotes` decides which capabilities are exposed and how each call reaches the right session's agent; `gateway` carries the calls and their results between Client and Host. The stack runs over the application's shared Connection; streaming session data is deliberately outside it.

+## Packages
+
+The packages below provide the Remote layer; the package READMEs own the exhaustive contracts.
 
 | Package | Role | ctx key |
 |---|---|---|
-| [`remotes/`](remotes/README.md) | Host Agent/Session lookup policy and Client Remote contribution assembly | no service; configures `ctx.typert` and consumes `ctx.remote` |
-| [`gateway/`](gateway/README.md) | Host Typert dispatcher and Client Remote endpoint | `ctx.typertGateway` / `ctx.remote` |
+| [`remotes/`](remotes/README.md) | Chooses which Host capabilities and events the Client can consume. | — |
+| [`gateway/`](gateway/README.md) | Carries typed unary calls, multiplexed streams, and forwarded Host events. | `ctx.typertGateway` / `ctx.remote` |
+| [`session-controller/`](session-controller/README.md) | Owns Session commands, history streams, live control state, and Agent/Session identity policy. | `ctx.sessionController` / `ctx.remote.session` |
+| [`workspace-controller/`](workspace-controller/README.md) | Owns Workspace mutations and the complete Client Workspace projection. | `ctx.workspaceController` / `ctx.remote.workspace` |
 
-The runtime dependency direction is `remotes → gateway → connection → webserver`: the BFF consumes the shared `TypertClientRemote` contract, Gateway delegates transport to Connection, and Connection mounts on the HTTP server. Cordis service injection and Client module metadata preserve this order without importing the concrete Gateway from the Remotes Client entry.
+Remote calls run Client → Host over the application's shared Connection. API Gateway owns Remote transport, while the two controller packages own Session and Workspace behavior. Endpoints without a Remote definition fall through to the application's API Proxy.
 
-## Known Limitations and Deferred Work
+-----
 
-- Connection and WebServer remain at [`client/connection`](../client/connection/README.md) and [`host/webserver`](../host/webserver/README.md); a later package-only move can place them under `api/connection` and `api/webserver` without changing their service contracts.
-- The legacy API Proxy remains at [`host/apiproxy`](../host/apiproxy/README.md) as the fallback for methods not yet migrated to Remote. It consumes the Host resolver owned by `api-remotes` so migrated and legacy methods retain one Agent/Session identity policy.

-面向应用的 Remote 技术栈。`remotes` 负责 BFF 策略和选定的业务 API，`gateway` 则实现 Host 与 Client 环境共用的 Typert 一元 RPC endpoint。
+## 概述
+
+`api/` 组提供应用的 Remote 层：Client 环境可以调用运行在 Host 上的业务能力——管理目标、运行命令、查看插件清单、发现文件与会话引用——调用方式是类型化方法，并接收结果或转发的 Host 事件。`remotes` 决定暴露哪些能力、以及每次调用如何到达正确会话的 agent；`gateway` 在 Client 与 Host 之间承载调用及其结果。技术栈运行在应用共享的 Connection 之上；流式会话数据刻意不在其中。

+## Summary
+
 Two-sided Typert RPC endpoint for Host and Client Cordis environments. The Host entry provides `ctx.typertGateway`, while `@deepseek-ai/dsh-api-gateway/client` provides `ctx.remote`; both consume the same generated `InvocationDescriptor` contract and leave business selection to API Remotes. Connection carries unary request correlation, trust, and response envelopes, while Gateway owns multiplexed Remote streams.

 - Only strict generated contributions can mount on the Client face. SRC markers have no Client codec or type projection.
 - `$stream()` supervises carrier replacement but does not infer replay semantics; each domain owns its resume cursor or replacement-baseline validation and normal-end classification. Connection generations reopen the internal `$events` stream; one-way notifications are not replayed, while pending scoped waterfalls retain their event id across replay.
 - Lookup resolvers are configured per key; an individual Remote parameter or endpoint cannot currently select a live-only policy under the same `agent`/`session` key.
 - Forwarded events reach `$on` without business-payload projection or redaction. Ordinary notifications are not replayed after reconnect; Agent-scoped waterfalls project only the top-level Agent identity needed to select the Client Context and carry their own pending lifetime.

+## Summary
+
 Two-sided BFF for Host Remote capabilities selected by this application. The Host entry owns the forwarded-event selection and registers its application event source with API Gateway; the Client entry imports generated `/remote` artifacts as runtime values, mounts each contribution through `ctx.remote.$mount()`, and re-exports their declaration merges. Client business packages depend on this facade rather than the Gateway implementation or individual Remote runtime entries.

 [`@deepseek-ai/dsh-api-session-controller`](../session-controller/README.md) owns Agent and Session identity policy, including the Typert lookup resolvers used by other namespaces. This package only selects and mounts that generated Session contribution; it does not duplicate activation policy.
 
-The current Client assembly mounts Commands, Goal, dynamic Cordis, file and Session references, read-only Host plugin inventory, message feedback, Session Controller, and Workspace Controller contributions. Cordis effect ownership withdraws every contribution when this assembly unloads, while `@deepseek-ai/dsh-api-gateway/client` owns descriptor validation, traced namespace Services, direct and scoped methods, invocation, streams, and cancellation. The Client entry consumes the shared `TypertClientRemote` interface through Cordis and does not import the concrete Gateway. It re-exports the Gateway Client face's declaration merges type-only, so a consumer reaching the forwarded-event vocabulary through this facade gains no runtime edge to the Gateway implementation.

 The Host entry registers an independent allowlist listener set and queue for each Client stream. It rejects non-JSON ordinary-event arguments before enqueueing. For a waterfall, it projects only the top-level Agent identity and JSON request fields; a Client result must also be lossless JSON, while `next()` delegates to the following Host listener. The source attaches all listeners synchronously before `ctx.typertGateway.registerRemoteEvents()` exposes Gateway's internal `$events` logical stream, so its first `ready` item proves that incremental delivery is active. Withdrawing the registration aborts active streams; API Proxy does not participate in event forwarding or Connection generation.

 The Client adapter exposes `SessionEventStream`, a Gateway `RemoteJournalStream` bound to one ordinary or direct-subagent address.

Ordinary records cover `[event.seq, event.seq]`; packed rows cover `[event.seq, event.seq + memberCount - 1]`. A business, persistence, or unresolved continuity failure terminates the stream, while only physical carrier loss selects automatic resumption. `SessionControlStream` is a Gateway `RemoteSnapshotStream`; every generation opens with a complete process-local baseline, so reconnect replaces queue, jobs, and projection state instead of treating transient values as durable events.

 The Host controller serializes mutations whose correctness depends on current registry state and returns stable `WorkspaceError` values for expected failures. Its `follow()` stream synchronously attaches to durable Workspace changes, emits one complete baseline first, then emits ordered `upsert`, `remove`, `order`, and `archived` increments. A reconnect starts another generation with a replacement baseline, so consumers do not depend on receiving every increment while disconnected.
 
 The Client entry provides `ClientWorkspaceModel` and `createWorkspaceStateStream()`. The model owns Workspace rows, registry order, archived Session ids, unary mutation echoes, and stream/unary race resolution. A newer Host row wins by `updatedAt`; a committed stream order outranks an older unary response; a removed Workspace id cannot be resurrected by delayed data. The package exposes framework-neutral snapshots and subscriptions, leaving navigation policy and React hooks to the UI owner.

+The `attachment/` group provides durable image attachments: attach images to prompts and commands, and the harness saves them on your machine, shows them again in conversation history, and sends them to the model in later turns. The shipped `dsh` composition enables this with no setup. The capability and its storage are split across two packages, described below. Stored images survive restarts and are never deleted automatically, and only raster image formats are supported.

 # @deepseek-ai/dsh-attachment-local
 
 English | [中文](README.zh.md)
 
-The private local implementation of [`@deepseek-ai/dsh-attachment`](../attachment). Objects land at `<DSH_HOME>/attachments/v1/objects/<sha256-prefix>/<sha256>` and are addressed by an opaque `sha256:` id. Each process proves a home durable once by syncing every ancestor entry to the filesystem root. Writes use a private staging directory, a synced temporary file, an atomic exclusive hard-link publish, owner-read-only object permissions, and directory syncs on the publication path (POSIX; Windows relies on filesystem metadata journaling) so the reported reference survives a crash.
+## Summary
 
-Admission accepts at most 20 images and 200MiB of encoded source bytes per message. Each source may use up to 20MiB, 64,000,000 pixels, and 8192px per side. It then prepares a provider-independent normalized attachment. EXIF orientation is applied, metadata and color profiles are removed, pixels become 8-bit sRGB/sRGBA, and the raster is reduced proportionally to the `normalizedImageMaxPixels` total-pixel budget (2048x2048 by default) with a `normalizedImageMaxDimension` long-edge cap (8192px by default), so extreme aspect ratios keep their short-edge resolution instead of collapsing under a long-edge rule. The normalized attachment has its own `normalizedImageMaxBytes` encoded-byte target (4MiB by default). Transparent pixels are retained; Sharp/libvips may omit an alpha plane whose samples are all opaque. Sources with an alpha channel encode as WebP (effort 0) and opaque sources as JPEG, both on the quality ladder 85, 75, 60. Each ladder step runs only after the preceding step exceeds the target, and when every step exceeds it the smallest output is kept; provider byte caps stay enforced by the route that transmits the bytes. A clean, single-frame 8-bit sRGB/sRGBA PNG, JPEG, or WebP already within both normalization limits passes through byte-identically; 16-bit PNG, GIF, animated input, metadata, orientation, and incompatible color spaces force conversion. The source and converted attachment are each fully decoded once. `saveImages` prepares and verifies every normalized attachment once before publishing the batch, so validation failure leaves no partial references and commit does not repeat full image encoding.
+This package provides the local storage and image-processing backend for attachments: source images are validated, oriented, stripped of metadata and color profiles, normalized to 8-bit sRGB/sRGBA, and saved below `DSH_HOME`; route-specific request versions are derived and cached separately. It is what the shipped `dsh` composition uses, so durable image attachments work without configuration. Identical normalized images are stored only once, concurrent reads of one request variant share work, and stored images stay readable after later admission-limit changes. Storage is local to this machine — other hosts cannot read these images — and objects are never deleted automatically.
 
-Request versions live below `<DSH_HOME>/attachments/v1/request-images/`. `readImageRequest` scales the stored normalized attachment under a total-pixel budget without enlargement, then applies a separate encoded-byte target. The request encoder uses the same alpha routing and quality ladder as normalization, WebP (effort 0) at 85, 75, 60 for alpha sources and JPEG at those qualities for opaque sources, executed lazily and keeping the smallest output when every quality exceeds the target. Its cache identity includes the attachment id, transform version, pixel and byte budgets, and fixed encoder settings. Cached bytes are header-probed for format, 8-bit sRGB/sRGBA, dimension, and alpha facts before use; a mismatch regenerates the entry. Concurrent calls for one identity share one transform and cache write; cancelling one waiter does not cancel the shared work. Callers compose ordered batches from singular reads, while the service's FIFO limiter applies `imageCompressionConcurrency` to simultaneous normalization and request transforms. The setting ranges from 1 through 8 and defaults to 2; file publication remains ordered after preparation.
+## Table of Contents
 
-`DSH_HOME` resolves through the shared path policy: explicit config, `$DSH_HOME`, then `~/.dsh`. Session logs contain only the reference and verified metadata. `imageHostPath` derives the normalized object's absolute host path and does not inspect the tool execution world. At request assembly, an LLM consumer asks the mounted filesystem to map that host object into its execution world. A host-backed filesystem returns a process path; a remote filesystem without a shared mount returns no path. The mapped path is absent from durable history and from `RequestImageAttachment`. `readImage` forwards optional cancellation into the filesystem read, observes it around verification, and preserves it instead of wrapping it as `ATTACHMENT_READ_FAILED`.

+## Use this package
+
+In the default composition, attach images to a prompt or command and they are stored on this machine automatically. If you compose your own setup, mounting this one plugin gives you durable image attachments.
+
+### Minimal configuration
+
+Mount the plugin with no required configuration. The defaults below define what you can attach; the generated configuration catalog is the exhaustive source for every field.
+
+```yaml
+- name: '@deepseek-ai/dsh-attachment-local'
+```
+
+| Field | Default | Meaning |
+|---|---|---|
+| `dshHome` | resolved | Explicit harness home; omitted follows `$DSH_HOME`, then `~/.dsh` |
+| `maxImageBytes` | `20 MiB` | Maximum encoded source bytes accepted for one image |
+| `maxImagesPerMessage` | `20` | Maximum image count accepted in one submitted message |
+| `maxMessageImageBytes` | `200 MiB` | Maximum aggregate encoded source bytes in one submitted message |
+| `maxImagePixels` | `64,000,000` | Maximum source width multiplied by height |
+| `maxImageDimension` | `8192` | Maximum source width or height |
+| `normalizedImageMaxPixels` | `2048 × 2048` | Total-pixel budget of the stored normalized image |
+| `normalizedImageMaxDimension` | `8192` | Maximum long edge after applying the total-pixel budget |
+| `normalizedImageMaxBytes` | `4 MiB` | Encoded-byte target; the smallest quality-ladder output is kept when none fits |
+| `imageCompressionConcurrency` | `2` | FIFO limit for concurrent normalization and request transforms |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-attachment-local) is the exhaustive source for every accepted field and its JSDoc.
+
+### Where your images are stored and how long they last
+
+Attached images are kept below `<DSH_HOME>/attachments/v1` on this machine. Stored images are never deleted automatically, identical images are stored only once, and a later tightening of the limits never makes already-saved images unreadable. If your images must be readable from another machine, this package is not the right fit.
+
+### What happens when you attach an image
+
+Attach an image and its source limits, media, dimensions, and pixels are checked before it is normalized and saved. EXIF orientation is applied, metadata and color profiles are removed, transparency is preserved, and the raster is reduced under a total-pixel budget plus a long-edge cap. Alpha images use WebP and opaque images use JPEG on the shared 85/75/60 quality ladder; the smallest output is retained when every candidate exceeds the byte target. An accepted image reappears in history and later turns, including after restart; the selected model route receives a cached request version and, when its filesystem maps the host object, a read-only execution-world path.
+
+### What can go wrong
+
+An image can be refused when you attach it: unsupported format, over the byte, pixel, or per-side dimension limits, or bytes that do not match their declared type. On a later read, an image that was deleted or corrupted on disk fails with a clear error. Each failure carries a stable code so the client and protocol adapters can explain it in their own words.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the durability and verification design behind the storage, and the write and read paths that realize it; observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design decisions
+
+- **Durability by fsync chain, not existence.** A synced file alone does not survive a crash when its directory entry never reached storage, so the write path syncs every ancestor entry to a process-proven boundary before a reference can reach a session checkpoint.
+- **Normalize once, project per route.** Admission persists one provider-independent normalized attachment; request projection derives deterministic variants without rewriting durable history.
+- **Lazy alpha-routed encoding.** Alpha images use WebP and opaque images use JPEG; quality candidates run in 85/75/60 order, and the smallest output is retained when none meets the encoded-byte target.
+- **Limits are write-time policy.** Byte, total-pixel, and per-side dimension limits bind admission only, so tightening them later never makes admitted history unreadable.
+
+### Write and read paths
+
+Objects land at `<DSH_HOME>/attachments/v1/objects/<sha256-prefix>/<sha256>`; equal bytes deduplicate to one object and one `sha256:` id. Before the first write, the process syncs every ancestor directory of the home down to the filesystem root once, so a directory another process created but has not yet synced is never mistaken for a safe boundary. Writes then stage bytes in `v1/tmp`, sync the temporary file, publish with an atomic exclusive hard link, and sync the publication directories — on Windows, filesystem metadata journaling owns entry durability. Once the save resolves, the reported reference is durable.
+
+Admission accepts up to 20 images and 200 MiB of source bytes per message; one source may use up to 20 MiB, 64 million pixels, and 8192 pixels per side. It applies orientation, removes metadata and color profiles, and normalizes under a 2048×2048 total-pixel budget, an 8192-pixel long edge, and a 4 MiB encoded-byte target. Extreme aspect ratios therefore retain their short-edge resolution. Clean single-frame 8-bit sRGB/sRGBA PNG, JPEG, or WebP input already within those limits passes through byte-identically; GIF, animation, metadata, orientation, 16-bit PNG, and incompatible color spaces force conversion.
+
+Request versions live below `<DSH_HOME>/attachments/v1/request-images/`. `readImageRequest` scales without enlargement to a route pixel budget, then applies a separate encoded-byte target through the same alpha routing and quality ladder. Its cache identity includes the attachment id, transform version, budgets, and fixed encoder settings; cached bytes are header-probed for format, 8-bit sRGB/sRGBA, dimensions, and alpha facts, and a mismatch regenerates the entry. Concurrent callers share one transform and cache write, while cancellation stops shared work only when no waiter remains. `imageHostPath` derives the normalized object's host path, and the mounted filesystem may map that path into its execution world without writing it to durable history.

 ## Model Experience
 
-Indirectly, through request descriptors. When the current execution filesystem maps this backend's host object, the model receives each retained or offloaded image's identity, dimensions, media type, read-only mapped path, matching extension for a writable copy, and a warning that normalization may have resized or re-encoded the upload.
+Indirectly, through request descriptors. A mapped execution filesystem lets the model see each image's identity, dimensions, media type, read-only process path, writable-copy extension, and normalization warning alongside the request bytes.
 
 #### KV Cache effect
 
-Normalization and request projection are deterministic. An unchanged attachment and route policy reuse identical cached request bytes on later turns. Execution-world path mapping is resolved separately and can change historical descriptor text without changing those bytes or their `variantId`.

 ## Known Limitations and Deferred Work
 
-- Objects are retained indefinitely; reference-aware garbage collection is deferred.
-- Animated GIF sources keep only their first frame; animation is outside the version-one image contract.
-- The normalization and request encoders are pinned by the installed sharp/libvips build; an encoder or transform-version upgrade re-addresses future normalized attachments or request variants while existing objects stay valid.

+
+This Dev Note is working context for maintainers: undecided directions and open questions. It is explicitly non-authoritative — shipped behavior and limits live in the sections above and the package code.
+
+#### Future: retention and remote storage
+
+Retention and garbage collection are deferred because resumed and forked sessions may share immutable objects, and a backend serving remote runtimes or shared storage would need its own durability proof. Both directions are undecided; the local storage currently retains every object under `DSH_HOME`.

 [English](README.md) | 中文
 
-这是 [`@deepseek-ai/dsh-attachment`](../attachment) 的私有本地实现。对象存放在 `<DSH_HOME>/attachments/v1/objects/<sha256-prefix>/<sha256>`，并通过不透明的 `sha256:` 标识符寻址。每个进程都会把每级祖先目录项同步到文件系统根目录，以此一次性证明 home 已持久化。写入使用私有暂存目录、经过同步的临时文件、原子且排他的硬链接发布、仅所有者可读的对象权限，并对发布路径执行目录同步（适用于 POSIX；Windows 依赖文件系统元数据日志），确保已报告的引用能够在崩溃后继续存在。
+## 概述
 
-每条消息最多准入 20 张图片，源图编码字节总量不超过 200MiB。每张源图不得超过 20MiB、64,000,000 像素和单边 8192px。随后生成提供方无关的规范化附件：应用 EXIF 方向，删除元数据和色彩配置文件，转换为 8-bit sRGB/sRGBA，并保持宽高比把像素总量缩到 `normalizedImageMaxPixels` 总像素预算内（默认 2048×2048），再受 `normalizedImageMaxDimension` 长边上限约束（默认 8192px），因此极端长宽比的图保留短边分辨率，而不会在长边规则下坍缩。规范化附件有独立的 `normalizedImageMaxBytes` 编码字节目标（默认 4MiB）。透明像素会保留；当所有 alpha 样本均为不透明时，Sharp/libvips 可能省略没有实际作用的 alpha 平面。带 alpha 通道的源图编码为 WebP（effort 0），不透明源图编码为 JPEG，共用质量阶梯 85、75、60。只有前一档超过目标时才会执行下一档；全部档位都超过目标时保留最小的产物，提供方字节硬上限仍由传输该字节的路由执行。已经处于两个规范化上限内的干净、单帧、8-bit sRGB/sRGBA PNG、JPEG 或 WebP 按字节原样直通；16-bit PNG、GIF、动图、元数据、方向和不兼容色彩空间都会触发转换。源图和转换后的附件各完整解码一次。`saveImages` 在发布任何批次成员前为每张图片各准备并验证一次规范化附件，因此校验失败不会留下部分引用，提交阶段也不会重复执行完整图片编码。
+本包提供附件的本地存储与图片处理后端：源图经过校验、方向修正、元数据与色彩配置移除，并规范化为 8-bit sRGB/sRGBA 后保存在 `DSH_HOME` 下；路由专用请求版本另行派生并缓存。随附的 `dsh` 组合使用的就是它，因此持久图片附件无需配置即可工作。相同规范化图片只存一份，同一请求变体的并发读取共享工作，即使后来收紧准入限制，已存图片仍然可读。存储仅限本机——其他主机无法读取这些图片——对象也永远不会自动删除。
 
-请求版本保存在 `<DSH_HOME>/attachments/v1/request-images/`。`readImageRequest` 在不放大小图的前提下，把存储的规范化附件缩放到总像素预算内，再应用独立的编码字节目标。请求编码器与规范化共用同一套 alpha 路由和质量阶梯：带 alpha 的源图依次尝试质量 85、75、60 的 WebP（effort 0），不透明源图依次尝试这些质量的 JPEG；候选按需执行，全部档位都超过目标时保留最小的产物。缓存身份包含附件 ID、变换策略版本、像素和字节预算及固定编码参数。缓存字节在使用前经头部探测校验格式、8-bit sRGB/sRGBA、尺寸和 alpha 事实；不匹配则重新生成该条目。同一身份的并发调用共享一次变换和缓存写入；取消一个等待方不会取消共享任务。调用方组合单数读取得到有序批次，服务的 FIFO 限流器通过 `imageCompressionConcurrency` 限制同时执行的规范化和请求变换。该配置范围为 1 至 8，默认值为 2；文件发布仍在准备结束后按顺序执行。
+## 目录
 
-`DSH_HOME` 按共享路径策略解析：显式配置、`$DSH_HOME`，最后是 `~/.dsh`。会话日志只包含引用和经过校验的元数据。`imageHostPath` 派生规范化对象的绝对宿主路径，不检查工具执行环境。组装请求时，LLM 消费方要求当前文件系统把该宿主对象映射到其执行环境。宿主文件系统返回进程路径；没有共享挂载的远程文件系统不返回路径。映射后的路径不进入持久历史，也不进入 `RequestImageAttachment`。`readImage` 会把可选取消信号传入文件系统读取、在校验前后观察该信号，并保留取消语义，而不会将其包装成 `ATTACHMENT_READ_FAILED`。

+附加的图片保存在本机的 `<DSH_HOME>/attachments/v1` 下。已存储的图片永远不会被自动删除，相同图片只会存储一份，之后收紧限制也绝不会让已保存的图片不可读。如果你的图片需要能从另一台机器读取，本包并不合适。
+
+### 附加图片时会发生什么
+
+附加图片后，会先检查源图限制、媒体类型、尺寸与像素，再完成规范化并保存。系统应用 EXIF 方向、移除元数据与色彩配置、保留透明度，并按总像素预算与长边上限缩小光栅。带 alpha 的图片使用 WebP，不透明图片使用 JPEG，共享 85/75/60 质量阶梯；全部候选都超过字节目标时保留最小输出。被接受的图片会重新出现在历史和后续轮次中，重启后也不例外；所选模型路由会收到缓存的请求版本，并在其文件系统可映射宿主对象时收到只读执行世界路径。
+
+### 可能出什么问题
+
+附加图片时可能被拒绝：格式不受支持、超出字节、像素或单边尺寸限制，或者字节与声明类型不符。之后读取时，磁盘上被删除或损坏的图片会以明确错误失败。每个失败都带有稳定错误码，客户端与协议适配器可以用自己的措辞解释。

+## 理解实现
+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释存储背后的持久性与校验设计，以及实现它的写入与读取路径；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计决策
+
+- **持久性靠 fsync 链，而非存在性。** 当目录项从未到达存储时，仅同步文件无法在崩溃后存活，因此写入路径会在引用可能到达会话检查点前，把每个祖先条目同步到进程已验证的边界。
+- **一次规范化，按路由投影。** 准入持久保存一份提供方无关的规范化附件；请求投影派生确定性变体而不改写持久历史。
+- **惰性 alpha 路由编码。** 带 alpha 的图片使用 WebP，不透明图片使用 JPEG；质量候选按 85/75/60 顺序运行，没有候选满足编码字节目标时保留最小输出。
+- **限制是写入时策略。** 字节、总像素与单边尺寸限制只约束准入，因此之后收紧它们绝不会让已接纳的历史不可读。
+
+### 写入与读取路径
+
+对象存放在 `<DSH_HOME>/attachments/v1/objects/<sha256-prefix>/<sha256>`；相同字节会去重为同一个对象和同一个 `sha256:` 标识符。首次写入前，进程会把 home 的每个祖先目录逐级同步到文件系统根目录，因此绝不会把另一个进程已创建但尚未同步的目录误认为安全边界。随后，写入过程把字节暂存到 `v1/tmp`、同步临时文件、以原子且排他的硬链接发布，并同步发布目录——在 Windows 上，文件系统元数据日志负责目录项持久性。保存成功后，已报告的引用即持久。
+
+准入允许每条消息最多 20 张图片与 200 MiB 源字节；单个源图最多 20 MiB、6400 万像素与单边 8192 像素。系统应用方向、移除元数据与色彩配置，并把规范化结果限制在 2048×2048 总像素预算、8192 像素长边和 4 MiB 编码字节目标内，因此极端宽高比会保留短边分辨率。已经满足限制的干净、单帧、8-bit sRGB/sRGBA PNG、JPEG 或 WebP 会逐字节直通；GIF、动画、元数据、方向、16-bit PNG 与不兼容色彩空间会触发转换。
+
+请求版本位于 `<DSH_HOME>/attachments/v1/request-images/`。`readImageRequest` 在不放大的前提下缩放到路由像素预算，再通过相同的 alpha 路由与质量阶梯应用独立编码字节目标。缓存身份包含附件 id、变换版本、预算与固定编码参数；缓存字节会先探测格式、8-bit sRGB/sRGBA、尺寸与 alpha 信息，不匹配时重新生成。并发调用方共享一次变换与缓存写入，且只在没有等待方时由取消停止共享工作。`imageHostPath` 派生规范化对象的宿主路径，挂载的文件系统可以把该路径映射进执行世界，而不会写入持久历史。

-The durable attachment seam. `ctx.attachments` validates and durably commits a provider-independent normalized image, then returns a serializable `ImageAttachmentRef`; consumers never persist browser paths, object URLs, provider URLs, local storage paths, or base64 in session events.
+## Summary
 
-Unsent composer images remain browser-owned temporary drafts. `validateImage` runs the complete admission policy without persisting. `saveImages` owns batch count and aggregate-byte limits, prepares every normalized attachment before publishing any member, then commits in order and returns references only after the complete batch succeeds. A later storage failure returns no partial references, although an earlier immutable content-addressed object may remain unreachable until reference-aware garbage collection exists. `AttachmentError.code` uses the closed `AttachmentErrorCode` string union. Its `ImageAdmissionErrorCode` subset marks caller-correctable image-input failures; `isImageAdmissionError` recognizes that subset at runtime so each protocol adapter can map its own error vocabulary. `saveImage` commits one accepted image before any model-visible session event is published and returns its `ImageAttachmentRef`. When normalization reduces the raster, the reference records the orientation-applied input size in `originalDimensions`. `readImage` verifies the normalized attachment against its logged metadata. `readImageRequest` deterministically derives a route-sized request version whose identity covers the attachment id, transform version, pixel and byte budgets, and encoder settings. The pure `requestImageDimensions` export computes that projection's aspect-preserving dimensions from a total-pixel budget, so providers and request pricing share one geometry. `imageHostPath` optionally exposes the provider-owned object's absolute host path; it makes no claim that the current model tools can read that path. An LLM consumer combines this location with the mounted filesystem's execution-world mapping when it serializes a request. That current access path remains separate from the request version and its `variantId`. Callers compose ordered batches with `Promise.all(refs.map(...))`; the local implementation still bounds compression through its instance limiter, cache, and singleflight. Callers may cancel reads and projections; implementations preserve cancellation instead of translating it into a storage failure.
+You can attach images to prompts and commands, and the harness keeps provider-independent normalized versions durably: each source image is admitted and normalized before your message is processed, reappears in conversation history, and is projected to the selected model route in later turns of the same session. The shipped `dsh` composition enables this with no setup. Attached images survive restarts, while browser paths, provider URLs, local storage paths, and base64 never enter durable session events. Only raster formats (PNG, JPEG, WebP, GIF) are accepted, and unsent composer drafts stay in the browser until you submit. Stored images are never deleted automatically, and non-image files, audio, and video are not supported yet.
 
-`admitEncodedImages(attachments, images)` is the shared wire entry used by every RPC endpoint that accepts browser uploads (the session prompt endpoint and the command executor): it enforces canonical base64 on every member, then delegates batch admission — limits, validation, ordered commit — to `saveImages`. The base64 upload form is `EncodedImageAttachment`, exported from `@deepseek-ai/dsh-attachment/types` so wire contracts can reference it.

+## Use this package
+
+Image attachments work end to end: attach an image to a prompt or a command, and it is saved, shown in history, and sent to the model without any further action from you. In the default `dsh` composition everything is already wired; when you compose your own setup, one plugin enables the capability.
+
+### Attach images to a prompt
+
+Attach one or more images to a user prompt in the client UI. Each source is checked, normalized to a provider-independent 8-bit sRGB/sRGBA raster, and saved before your message is processed; if any image is refused, the whole message fails and nothing is published. Supported source formats are PNG, JPEG, WebP, and GIF; a deployment controls source limits separately from normalized-storage and route-specific request limits. The one plugin below enables durable image attachments (the shipped base composition already mounts it):
+
+```yaml
+- name: '@deepseek-ai/dsh-attachment-local'
+```
+
+### Pass images to commands
+
+Commands that accept image input receive attached images the same way. If a command does not accept images, the harness refuses with an error message instead of silently dropping them.
+
+### Reuse images across the session
+
+Saved normalized images stay in conversation history and are projected into deterministic, route-sized request versions in later turns; after a restart, a resumed session shows and reuses the same images. When the current execution filesystem maps the stored host object, the request descriptor also carries a read-only process path that the model can inspect. When history or a request version is read back, the stored bytes are checked against what was recorded, so a missing, corrupted, or swapped image surfaces as an error rather than wrong bytes.
+
+### What can go wrong
+
+An image can be refused when you attach it — unsupported format, over the size, pixel, or dimension limits, or bytes that do not match their declared type — and the message then fails as a whole. Later, a history read can fail if the stored image was deleted or corrupted on disk. Failures carry stable codes so the client and protocol adapters can explain them in their own words.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the seam and the service operations that realize the user-visible behavior; observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design decisions
+
+- **Normalize and persist before event.** Every source is prepared and verified before the batch publishes in order, so the session log never references a partial or failed normalization.
+- **Immutable and retention-neutral.** Objects are immutable once published; resumed and forked sessions may share them, so reference-aware garbage collection is deferred rather than tied to any one session's deletion.
+- **Verify on read.** Reads check bytes and metadata against the logged reference before returning them, and request projections fully decode cached bytes, so a missing, corrupted, or swapped object fails closed.
+- **Role-neutral image blocks.** The `ImageBlock` content block in `dsh-llm` carries an `ImageAttachmentRef`; provider adapters resolve it into deterministic request versions with explicit pixel and byte budgets, while execution filesystems may map the immutable host object to a model-readable process path.
+- **Error routing by code.** `AttachmentError` re-implements the `HarnessError` shape instead of extending it because the base lives in `dsh-llm`, which depends on this package; consumers route on `code`, never on the prototype chain.
+
+### Service operations
+
+The service family runs one admission-and-storage flow: every entry point enforces source batch limits and canonical base64, prepares provider-independent normalized attachments before publishing any member, and commits them durably in input order without partial results. `readImageRequest` derives deterministic route-sized variants whose identity includes the attachment id, transform version, pixel and byte budgets, and encoder settings. The pure `requestImageDimensions` export computes each projection's aspect-preserving dimensions from a total-pixel budget, so providers and request pricing share one geometry. `imageHostPath` exposes an implementation-owned host location only to trusted same-process consumers that need execution-world mapping. Callers compose ordered batches while the implementation owns compression concurrency, caching, and singleflight. Reads and projections preserve caller cancellation. Failures carry stable machine-readable codes, and the caller-correctable admission subset is recognizable at runtime so each protocol adapter maps its own vocabulary; the exact per-operation contracts live in [`src/index.ts`](src/index.ts) and [`src/error.ts`](src/error.ts).

 ## Model Experience
 
-Indirectly, through the role-neutral core `ImageBlock` and provider adapters that resolve its durable reference into an exact request version. Request descriptors expose the complete attachment id and actual request dimensions. When the attachment backend exposes a host object and the current execution filesystem maps it, the descriptor also exposes the resulting read-only path; it states that normalization may have resized or re-encoded the upload.
+Indirectly, through the provider adapter, which resolves each durable reference into an exact request version and sends its stable attachment id and actual dimensions beside the image. When the execution filesystem maps the stored object, the descriptor also includes a read-only process path and a matching extension for a writable copy.
 
 #### KV Cache effect
 
-Adding an image changes the provider request and therefore invalidates the affected request suffix. A changed execution-world path can also change historical descriptor text without changing the deterministic request version.
+Adding an image changes the provider request and therefore invalidates the affected request suffix.
 
 ## Known Limitations and Deferred Work
 
-- Version one accepts PNG, JPEG, WebP, and GIF only.
-- Retention and garbage collection are deferred because resumed and forked sessions may share immutable objects.
-- Generic files, audio, video, and persistent unsent drafts require separate lifecycle and provider contracts.
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits describe what image attachments can and cannot do; they are current package constraints, not a task backlog.
+
+- **Raster images only** — PNG, JPEG, WebP, and GIF are accepted; generic files, audio, and video are not supported yet.
+- **Images are never deleted** — stored images are retained indefinitely; nothing removes them automatically.
+- **Unsent drafts are not saved** — a composer draft stays in the browser until you submit the message.

+### Dev Note
+
+<details>
+<summary>Working context for maintainers — click to expand</summary>
+
+This Dev Note is working context for maintainers: undecided directions and open questions. It is explicitly non-authoritative — shipped behavior and limits live in the sections above and the package code.
+
+#### Future: reference-aware garbage collection
+
+Resumed and forked sessions may share immutable objects, so any retention policy needs a reference model that accounts for session lineage before objects can be collected. No decision is recorded yet; the local backend currently retains everything.
+
+#### Future: non-image attachments and assistant-side output
+
+Generic files, audio, and video would need separate lifecycle and provider contracts, and the role-neutral `ImageBlock` leaves assistant-side image output as forward compatibility — current production adapters declare text-only output, so only user content carries images. Both directions are undecided.

-持久附件服务边界。`ctx.attachments` 校验并持久提交提供方无关的规范化图片，随后返回可序列化的 `ImageAttachmentRef`；消费方绝不会在会话事件中持久保存浏览器路径、对象 URL、提供方 URL、本地存储路径或 base64。
+## 概述
 
-未发送的输入区图片仍是由浏览器持有的临时草稿。`validateImage` 运行完整准入策略但不执行持久化。`saveImages` 负责批次图片数量和总字节限制，在发布任何成员前准备全部规范化附件，然后按顺序提交，并且只在完整批次成功后返回引用。后续存储失败不会返回部分引用，但较早写入的不可变内容寻址对象可能保持不可达，直至具备按引用感知的垃圾回收。`AttachmentError.code` 使用封闭的 `AttachmentErrorCode` 字符串联合类型。其 `ImageAdmissionErrorCode` 子集标记可由调用方修正的图片输入失败；`isImageAdmissionError` 在运行时识别该子集，使每个协议适配器可以映射自己的错误词汇。`saveImage` 会在发布任何模型可见的会话事件前提交一张已接受的图片，并直接返回 `ImageAttachmentRef`。规范化过程缩小图片时，引用会通过 `originalDimensions` 记录应用方向后的输入尺寸。`readImage` 根据已记录的元数据校验规范化附件。`readImageRequest` 确定性派生路由所需的请求版本，其身份覆盖附件 ID、变换策略版本、像素和字节预算及编码参数。纯函数导出 `requestImageDimensions` 按总像素预算计算该投影的保持宽高比尺寸，使提供方与请求定价共享同一套几何计算。`imageHostPath` 可以给出提供方所持对象的绝对宿主路径，但不保证当前模型工具能够读取它。LLM 消费方在序列化请求时将这个位置与当前文件系统提供的执行环境映射组合起来。解析出的访问路径独立于请求版本及其 `variantId`。调用方通过 `Promise.all(refs.map(...))` 组合有序批次，本地实现仍通过实例级限流器、缓存和 singleflight 限制压缩并发。调用方可以取消读取和投影；实现保留取消结果，不把它转换为存储失败。
+你可以把图片附加到提示词和命令中，harness 会持久保存提供方无关的规范化版本：每张源图都会在你的消息被处理前准入并规范化，重新出现在对话历史中，并在同一会话的后续轮次投影到所选模型路由。随附的 `dsh` 组合无需任何配置即可支持这一点。已附加的图片在重启后依然存在，而浏览器路径、提供方 URL、本地存储路径与 base64 绝不会进入持久会话事件。只接受光栅格式（PNG、JPEG、WebP、GIF），未发送的输入区草稿在提交前仍留在浏览器中。已存储的图片永远不会被自动删除，通用文件、音频和视频暂不支持。
 
-`admitEncodedImages(attachments, images)` 是每个接受浏览器上传的 RPC 端点（会话 prompt 端点与命令执行器）共用的 wire 入口：它对每个成员强制执行规范 base64，随后把批量准入——限额、校验、有序提交——委托给 `saveImages`。base64 上传形式为 `EncodedImageAttachment`，从 `@deepseek-ai/dsh-attachment/types` 导出，供 wire 契约引用。

+## 使用本包
+
+图片附件端到端可用：把图片附加到提示词或命令，它会自动保存、显示在历史中并发送给模型，无需你再做任何操作。在默认 `dsh` 组合中一切都已接好；自行组合时，一个插件即可启用该能力。
+
+### 在提示词中附加图片
+
+在客户端 UI 中向用户提示词附加一张或多张图片。每个源图都会在你的消息被处理前接受检查、规范化为提供方无关的 8-bit sRGB/sRGBA 光栅并保存；如果任何一张图片被拒绝，整条消息都会失败且不会发布任何内容。支持的源格式为 PNG、JPEG、WebP 与 GIF；部署方分别控制源图限制、规范化存储限制与路由专用请求限制。下面这一个插件即可启用持久图片附件（随附的 base 组合已经挂载它）：
+
+```yaml
+- name: '@deepseek-ai/dsh-attachment-local'
+```
+
+### 把图片传给命令
+
+接受图片输入的命令以相同方式接收附加图片。如果某个命令不接受图片，harness 会以错误消息拒绝，而不是静默丢弃。
+
+### 在整个会话中复用图片
+
+已保存的规范化图片会保留在对话历史中，并在后续轮次投影为确定性的路由尺寸请求版本；重启后，恢复的会话会显示并复用相同的图片。当前执行文件系统可以映射已存宿主对象时，请求描述符还会携带模型可检查的只读进程路径。回读历史或请求版本时，已存储的字节会与记录的内容比对，因此缺失、损坏或被替换的图片会以错误形式呈现，而不是错误的字节。
+
+### 可能出什么问题
+
+附加图片时可能被拒绝——格式不受支持、超出大小、像素或尺寸限制，或者字节与声明类型不符——此时整条消息失败。之后，如果磁盘上的图片被删除或损坏，历史读取也可能失败。失败带有稳定错误码，客户端与协议适配器可以用自己的措辞解释它们。

+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释 seam 背后的设计决策，以及实现用户可见行为的服务操作；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计决策
+
+- **事件前完成规范化与持久化。** 每个源图都会在批次按序发布前完成准备与校验，因此会话日志绝不会引用部分完成或规范化失败的对象。
+- **不可变且保留策略中立。** 对象一经发布即不可变；恢复和 fork 后的会话可能共享它们，因此引用感知的垃圾回收被推迟，而不是与任何单个会话的删除绑定。
+- **读取时校验。** 读取在返回前把字节和元数据与记录的引用比对，请求投影还会完整解码缓存字节，因此缺失、损坏或被替换的对象都会失败关闭。
+- **角色无关的图片块。** `dsh-llm` 中的 `ImageBlock` 内容块携带 `ImageAttachmentRef`；提供方适配器以显式像素与字节预算把引用解析为确定性请求版本，执行文件系统则可以把不可变宿主对象映射为模型可读的进程路径。
+- **按错误码路由。** `AttachmentError` 重新实现 `HarnessError` 的结构而不是继承它，因为基类位于 `dsh-llm`，而后者依赖本包；消费方按 `code` 路由，绝不依赖原型链。
+
+### 服务操作
+
+服务族运行同一条准入与存储流程：每个入口都强制执行源批次限制与规范 base64，在发布任何成员前准备提供方无关的规范化附件，再按输入顺序持久提交而不产生部分结果。`readImageRequest` 派生确定性的路由尺寸变体，其身份包含附件 id、变换版本、像素与字节预算及编码参数。纯函数导出 `requestImageDimensions` 会按总像素预算计算每个投影保持宽高比的尺寸，使提供方与请求定价共享同一套几何计算。`imageHostPath` 只向需要执行世界映射的受信任同进程消费方暴露实现拥有的宿主位置。调用方组合有序批次，而实现拥有压缩并发、缓存与 singleflight。读取和投影保留调用方的取消语义。失败带有稳定且机器可读的错误码，运行时即可识别可由调用方修正的准入子集，让每个协议适配器映射自己的词汇；各操作的确切约定见 [`src/index.ts`](src/index.ts) 与 [`src/error.ts`](src/error.ts)。

 # boot/ — shared app-bin boot glue
 
 English | [中文](README.zh.md)
 
-The channel-neutral boot library shared by `apps/cli` and test-only Loader fixtures.
+## Summary
+
+The boot group provides what every dsh app bin needs to start: `app-boot` turns a `cordis.yml` plus your environment and patch layers into a running app with clear failure messages, and `cmdline` lets the app own its command-line flags and `--help`. With these packages you can run `dsh` or write a new application or test fixture that boots the same way. Both are libraries imported by `apps/cli` and test-only Loader fixtures, never plugins a composition loads. This page maps the group; each package README owns its per-package contract.

-由 `apps/cli` 与仅限测试的 Loader fixture 共享、与渠道无关的启动库。
+## 概述
+
+boot 组提供每个 dsh app bin 启动所需的全部能力：`app-boot` 把 `cordis.yml` 连同你的环境与 patch 层变成运行中的应用，并给出清晰的失败信息；`cmdline` 让应用持有自己的命令行 flag 与 `--help`。借助这些包，你可以运行 `dsh`，也可以编写以同样方式启动的新应用或测试 fixture。两者都是 `apps/cli` 与测试专用 Loader fixture 导入的库，绝不是组合加载的插件。本页是组的映射；各包 README 负责各自的包级约定。

-Shared Loader boot glue for [`dsh`](../../../apps/cli/README.md) profiles, including the CLI packaged by the [Python runtime wheel](../../../python/README.md). The product launcher owns profile composition and process lifecycle. Direct-config helpers serve lower-level embedders and tests; they do not define another supported application entrypoint.
+## Summary
 
-| Export | Role |
+`dsh-app-boot` is the shared Loader boot library behind `dsh` profiles, including the CLI packaged by the Python runtime wheel. It loads environment layers, composes profile bundles and patches, boots every plugin, and returns the running app or identifies the failed plugin and cause. Product applications use the `dsh` launcher instead of publishing separate bins; direct-config helpers remain only for lower-level embedders and tests. You can preview the effective configuration before booting, select live or startup-only patch application per profile, and let a terminal-owning app restore its terminal before a fatal exit.

+## Use this package
+
+Starting an app with this package is a small, explicit entry point: you give it a config file and it runs the whole boot. This section covers what you can do and what you get; the helper calls behind each outcome are documented in the folded implementation section.
+
+### When to use it
+
+Use it when implementing the shared `dsh` launcher or embedding its lower-level boot helpers. Product features belong in profile bundles instead of new application bins; code that only adds plugins to an already-running app mounts those plugins directly.
+
+### Starting the app
+
+You give your entry point a config file, and the process starts the whole app: it loads your environment layers, applies patches and profiles, boots every plugin, and returns once the app is running. In replay mode it boots the sibling `cordis.snapshot.yml` instead, so a recorded session reproduces identically. The smallest entry point is two calls:
+
+```text
+installFailLoud('dsh')
+const ctx = await boot('dsh', resolveConfigPath(argv[2], process.env.DSH_SNAPSHOT))
+```
+
+With that entry point, success looks like a running app with every plugin active; failure is never silent — one labelled line names the failing plugin and the stage, and the process exits nonzero. The app context is torn down before the error is reported, so nothing keeps running half-started.
+
+<a id="profiles"></a>
+### Profiles
+
+A profile is how one dsh installation ships different app surfaces: `web`, `headless`, `acp`, `sdk`, and `sdk-minimal` start distinct compositions from the same launcher. A profile lives at `$DSH_HOME/profiles/<name>` and combines installable bundles, its own `cordis.patch.yml`, and `patchReload: live | startup`; omitted reload policy keeps the historical `live` default for custom profiles. The shipped `web` template uses live reload, while the other shipped templates apply patches only at startup. `sdk-minimal` names only its standalone bundle; the other templates retain base-plus-mode stacks. `dsh plugin` creates custom profiles, and a missing bundle or one without a patch declaration fails startup loudly.
+
+Your machine-local preferences also live in the Harness home:
+
+- **`.env`** — your ordinary environment layers: the invoking directory's file outranks the Harness-home file, and both sit below the inherited environment. Variables that decide how the process starts (`PATH`, proxies, `DSH_*`, `XDG_*` and similar) are rejected from files: export them instead. For a non-product bin that just wants one directory's `.env`, a missing file is fine and an unloadable one prints one labelled warning line.
+- **`cordis.patch.yml`** — your tweak layer, applied after every bundle layer (per-profile first, then the home-level file, which therefore outranks it): replace one entry's whole config (restating the fields you keep), insert new entries, or interpolate `!!js` expressions at boot. A patch naming an entry that does not exist prints a stderr warning; an empty or comments-only file fails boot — disable the layer with `[]` instead.
+
+Profiles with `patchReload: live` watch both user patch files: a valid edit recomposes without restart, while a rejected edit leaves the last good app running. A `startup` profile installs neither those watchers nor the launcher's watch-only HMR fallback.
+
+### Previewing the effective configuration
+
+Before you boot, you can print the exact configuration the app will mount: the dump shows the composed entry list with `!!js` expressions verbatim, grouped under comments naming each source file and the patch layers that changed it, as one loadable YAML document. Patches that match no row are reported with their layer label; a missing, unparsable, or invalid config fails the dump.
+
+### What you see when startup fails
+
+Startup failure is a single labelled line plus a nonzero exit — never a silent hang or a raw stack dump. The message names the failing plugin; a plugin that threw keeps its original error, and an entry that never started is reported with the services it was waiting for.
+
+If your app owns the terminal, it can hand the terminal back before the process exits, so your shell is never left in raw mode. The handoff is bounded: a stuck cleanup delays the fatal exit but never cancels it.
+
+### Telling the agent where the harness lives
+
+When your app boots a model-backed agent, you can tell the agent where the DSH implementation checkout lives: it learns that path and that it must not infer the working directory from it — it should use `pwd`. The instruction appears once near the top of the system prompt. Apps without a system prompt service skip it; in development, reloading the system prompt drops it until the next boot.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the outcomes above are realized and points at the code that realizes them; everything here is developer-facing and not needed to use the package.
+
+### Design notes
+
+- **Channel-neutral library.** The package carries no loader hooks and no dev-mode surface; the [`dsh` app](../../../apps/cli/README.md) owns its Node source-launch hook and consumes these helpers for the boot sequence, and built consumers use plain Node package resolution.
+- **Two Loader builtins.** `mountRootInclude` registers `cordis:include` and `cordis:group` as Loader builtins: a group row gives one `isolate` realm to a provider and its consumers together, and an agent preset outside this workspace cannot resolve `@deepseek-ai/cordis-plugin-group` by name. Both load through the ambient module pipeline rather than the included tree's own specifier resolution.
+- **Profile module fallback.** Bare plugin specifiers resolve through the Loader from the config directory. Plain Node maintains one symlink per package in the installation dependency closure. A packaged executable instead reads each installed export map with Node ESM conditions and writes real proxy packages that re-export virtual module URLs, because an operating-system symlink cannot enter pkg's `/snapshot` tree. Missing exports stay unavailable, malformed maps fail startup, and a cross-process writer lock replaces stale entries without exposing partial proxies.
+- **One rejection checkpoint.** `assertEntriesActivated` keeps the exact reasons it folds into the boot diagnostic visible through the next process rejection checkpoint, so `installFailLoud` coalesces Loader's duplicate notification while unrelated unhandled rejections remain fatal.
+- **Two-stage failure labels.** `boot()` distinguishes `host preparation failed` — `prepare` threw before any config-tree entry mounted — from `plugin tree failed to load`, and appends the deepest plugin error's stack so the startup diagnostic preserves the original activation error instead of only the wrap chain.
+
+### Helper behavior
+
+The exports each own one stage of the boot: config resolution and snapshot replay, layered environment loading, fail-loud reporting, activation auditing, patch parsing, root-include mounting, config dump rendering, live patch watching, profile composition, and the harness-source section. Per-export contracts live in the code, not this README — see [`src/index.ts`](src/index.ts) and [`src/profile.ts`](src/profile.ts).
+
+### Source map
+
+| File | Role |
 |---|---|
-| `resolveConfigPath(path, snapshotMode, cwd?)` | Absolute config path; `snapshotMode === 'replay'` swaps a `cordis.yml`/`.yaml` basename for its sibling `cordis.snapshot.yml` |
-| `loadEnv(binName, dir?, warn?)` | Load the gitignored `.env` (Node `process.loadEnvFile`); absent file is fine, an unloadable one warns a single labelled line (default: stderr) |
-| `loadLayeredEnv(binName, cwd?, warn?)` | Build the product CLI's frozen inherited > project `.env` > user `.env` snapshot, reject bootstrap-only file variables, and materialize accepted file values without replacing inherited ones |
-| `installFailLoud(binName, proc?, release?)` | Turn an unhandled boot or later Loader rejection into one labelled stderr line + `exit(1)`; the optional `release` teardown is awaited between the two (bounded by `FAIL_LOUD_RELEASE_TIMEOUT_MS`) so a terminal-owning surface restores the terminal before exit; returns the uninstaller |
-| `FAIL_LOUD_RELEASE_TIMEOUT_MS` | How long `installFailLoud` waits for its `release` hook; a wedged disposer delays the fatal exit, never cancels it |
-| `assertEntriesLoaded(ctx, binName)` | Throw when a settled tree holds an enabled entry with no fiber, reporting every unresolved plugin name as a Cordis startup failure |
-| `assertEntriesActivated(ctx, binName)` | Include the `assertEntriesLoaded` check, then await every enabled entry after the Loader settles; throw with each failed plugin's original stack or each pending plugin's unresolved services |
-| `loadOptionalPatches(binName, file)` | Parse an optional patch-list file (a profile's `cordis.patch.yml`) — a top-level YAML array of include `PatchOptions` (id-targeted config overrides, `insert` lists, `!!js` allowed); absent file → `undefined`, an unreadable/unparsable/non-array file throws |
-| `loadOverlayPatches(binName, file)` | Parse a required top-level YAML array containing the same include `PatchOptions` entries described above; relative plugin names in inserted rows resolve beside this file, while a patch `name` used to assert an existing row stays literal; a missing file also throws because the caller named it |
-| `mountRootInclude(ctx, absoluteConfigPath, patches?, bareModuleBaseUrl?)` | Register the statically imported `cordis:include` and `cordis:group` builtins, mount the include, and retain the exact root entry used by user patch-layer HMR; an optional module base anchors bare package names to the installed host while relative names stay config-relative |
-| `watchUserPatches(ctx, options)` | Register the named patch file with the existing Cordis HMR service; each add/change/removal transactionally recomposes the full patch list through the caller's `compose` closure (app-owned layers around the current user layer) and returns an async disposer |
-| `resolveProfileDir` / `initProfile` / `loadProfile` / `readProfileManifest` / `writeProfileManifest` / `resolveBundleDir` / `composeEntries` / `healProfilesModuleFallback` / `PROFILE_TEMPLATES` / `DEFAULT_PROFILE_BUNDLES` / `DEFAULT_PROFILE_PATCH_RELOAD` / `PROFILES_DIR` / `PROFILE_PATCH_FILENAME` | Profile machinery and patch-file lifecycle (see [Profiles](#profiles)) |
-| `boot(binName, absoluteConfigPath, patches?, prepare?, bareModuleBaseUrl?)` | Create the root context, expose `dshHomePath(...segments)` to Loader `!!js` config expressions, install Loader, run optional host preparation before config-tree entries mount (`prepare` may use Loader and provide launcher-owned context slots), then mount and await the include tree, assert entries loaded and activated, and return the root context — or dispose the partial context and reject a labelled error; the optional module base has the same resolution semantics as `mountRootInclude` |
-| `renderConfigDump(binName, absoluteConfigPath, layers, warn?)` | Compose the base config and labeled overlay layers offline with the include's own parser and patch algorithm (`entryListSchema`/`applyEntryPatches`), so the result equals what `boot()` mounts, and render YAML with `!!js` expressions verbatim; each run of rows that shares one source file and the same patch layers is preceded by a `# ==` comment naming that file and those layers, keeping the output one loadable document; a patch matching no row goes to `warn` with its layer label (default: one stderr line), and read, parse, or field validation failures throw |
-| `addHarnessSourceSection(ctx, sourceRoot)` | Add a global `harness:source` prompt section (ordered just after the harness identity, before the persona) telling the agent the on-disk path to the DSH implementation checkout while warning it not to infer the current working directory from that path and to use `pwd` instead; a no-op returning `undefined` when the booted tree has no `systemPrompt` service. The section is registered against that service's fiber, so a dev HMR reload of the system prompt drops it until the next boot |
-| `HARNESS_SOURCE_SECTION` | The `'harness:source'` section name `addHarnessSourceSection` registers under |
+| [`src/index.ts`](src/index.ts) | Boot helpers: config resolution, environment loading, fail-loud guard, activation audit, patch parsing, config dump, harness-source section |
+| [`src/profile.ts`](src/profile.ts) | Profile discovery, initialization, bundle resolution, module fallback |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; boundary and replay tests cover the protocol mapping) |
 
-Loader settlement rejects import and lifecycle failures with the failing entry and stage; `boot()` disposes the partial context and wraps that failure with the bin name. Entries settlement leaves behind are audited separately: `assertEntriesLoaded` turns an enabled fiber-less entry into a rejection naming every unresolved plugin, and `assertEntriesActivated` awaits each failed fiber to include its original stack in the startup rejection and names each pending entry's unresolved services. Before throwing, the audit marks those exact rejection reasons through one process checkpoint so `installFailLoud` coalesces Loader's duplicate notification while every unrelated unhandled rejection remains fatal.
+</details>
 
-The Loader mounts entries concurrently, so a surface can already own the terminal when something else fails: exiting without the tree's own teardown would leave raw mode, bracketed paste, and the keyboard protocol set on the user's shell, and an in-flight terminal query's reply would land as literal text at the next prompt. A config-tree failure settles through `boot()`, whose disposal of the partial context runs the surface's own shutdown before the labelled rejection. For the rejections `boot()` cannot see — a plugin's detached async work rejecting during or after mounting — a terminal-owning bin passes `release` to dispose the tree before the exit commits; `dsh` captures the root context in `boot()`'s `prepare` hook rather than from its return value so the hook covers the whole mounting window. While a release is in flight the handler stays installed and latched: the first rejection is the reported one, and later rejections (teardown's own included) are swallowed rather than becoming uncaught and killing the process mid-teardown.
+-----
 
-`cordis:group` is registered beside `cordis:include` so a composition can give one `isolate` realm to a provider and its consumers together. Both load through the ambient module pipeline rather than the included tree's own specifier resolution, which is what lets a composition outside this workspace — an agent preset under the Harness home — use a group row at all.
+<a id="further-exploration"></a>
+## Further Exploration
 
-Bare plugin specifiers in a config (`@deepseek-ai/dsh-*`, npm packages) resolve through the Cordis Loader's internal module loader. They resolve from the config directory by default; a closed runtime passes `bareModuleBaseUrl` to `boot` or `mountRootInclude` so its installed package tree remains authoritative even when the config lives inside another Node project. Relative specifiers always resolve against the config directory. Repository bins install Loader's optional `node-addon-require-builtin` peer; external callers must supply it or install plugins where plain Node import resolution can find them. The built `dsh-app-boot` artifact embeds the statically mounted Include implementation while leaving Loader external, so the include tree and host bind to one Loader peer. The `pnpm dsh` source path additionally maps manifest-declared workspace packages to their TypeScript source; its configuration gate requires every shipped raw/Web bare plugin to appear in the resolver manifest's `dependencies`.
+Read these pages when the package-level contract is not enough. They move from the shared boot mechanics to the composition model and the decision evidence behind it.

-## Profiles
-
-A profile is a directory under `$DSH_HOME/profiles/<name>` (the Harness home resolves through [`resolveDshHome`](../../util/home-paths/README.md): `$DSH_HOME`, else `~/.dsh`) holding a `package.json` — out-of-tree plugin `dependencies` plus the profile manifest `dsh.profile` with its ordered `bundles` layer list and `patchReload: live | startup` — and the user's own `cordis.patch.yml`. `live` watches the profile and home-level patch files after boot; `startup` applies every layer once. A missing value keeps the historical `live` default for custom profiles. A bundle is an npm package whose manifest declares `"dsh": { "bundle": { "patch": "./cordis.patch.yml" } }`; `loadProfile` resolves each `dsh.profile.bundles` name two-anchored (the dsh installation first, then the profile directory) and fails loud on a listed package without a bundle declaration. `composeEntries` applies patch layers over an empty entry list through the include's own `applyEntryPatches`, so composition, flag derivation, and config dumps cannot drift from what boots. `healProfilesModuleFallback` maintains the flat `$DSH_HOME/profiles/node_modules` directory. Plain Node writes one symlink per package in the installation dependency closure; a pkg executable resolves available explicit exports directly from each installed manifest with Node ESM import conditions and writes real proxy packages that re-export virtual module URLs, because an operating-system symlink cannot enter pkg's `/snapshot` tree. Export targets absent from an installed package remain unavailable without blocking its other exports; malformed export maps fail startup. An executable-only or declaration-only package with no module entry produces no proxy. A complete matching generation returns without acquiring the writer lock. A missing or stale entry acquires the cross-process lock, rechecks the full generation, and repairs it without exposing partial proxies; either carrier replaces the other carrier's managed entry. Both forms let profile plugins resolve installation packages through Node's ordinary parent walk and preserve one module instance for external plugin peers. `PROFILE_TEMPLATES` auto-initializes `web` with live reload and `headless`/`sdk`/`sdk-minimal`/`acp` with startup-only patches; `sdk-minimal` lists only its standalone bundle, while the other templates retain their base-plus-mode stacks. Other names fail loud until `initProfile` creates them through `dsh plugin`. `loadProfile` normalizes an exact installation-owned bundle tuple and a missing reload choice to its shipped template while preserving every explicit reload choice and every other manifest field; any extra, missing, or reordered bundle makes the list user-owned and leaves it unchanged.
-
-User-level machine-local preferences also live in the Harness home:
-
-- **`.env`** — the product CLI's ordinary environment layers: the invoking directory's file outranks the Harness-home file, and both sit below the inherited environment. `loadLayeredEnv` snapshots each value's source, rejects [bootstrap-only file variables](../../../.agents/notes/implemented/architecture/2026-08-04-configuration-source-ownership.md#decision) case-insensitively, and materializes accepted values into `process.env` for Loader expressions and third-party libraries. Managed credentials live separately in [`.credentials.yaml`](../../credentials/credentials-local/README.md); a credential left in either `.env` remains a lower-priority fallback.
-- **`cordis.patch.yml`** (home level) and **`profiles/<name>/cordis.patch.yml`** — the user patch layers, applied after every bundle layer (per-profile first, then the home-level file, which therefore outranks it): an id-targeted patch replaces the named entry's whole `config` (restate unchanged fields), `insert` adds entries, and `!!js` expressions interpolate at mount. A patch naming an entry id absent from the composed tree is a stderr warning. An empty or comments-only file throws (it parses to nothing, not to a list); disable the layer with `[]`.
-
-Every `patchReload: live` profile keeps both user patch files live through `watchUserPatches`. The watcher targets the exact path even when the file or immediate parent does not exist, serializes bursts, and recomposes the user patches inside the caller's layer order (bundle layers below, overlays above). A rejected read, parse, or Loader candidate leaves the last good tree running and the HMR service broadcasts `hmr/config-update-failed(filename, Error)` after logging it; observer failures are contained. Disposing the context closes the watcher and drains an active refresh. A `startup` profile installs neither these watchers nor the launcher's watch-only HMR fallback.

 ## Model Experience
 
-Indirectly, through the plugin tree it loads, which determines the prompts, schemas, messages, and model adapter in the resulting application; the one export that contributes model-visible text, `addHarnessSourceSection`, does so only when a consumer calls it after boot.

 #### KV Cache effect
 
-No direct invalidation from `boot()`; a consumer that calls `addHarnessSourceSection` places one short line near the system prompt's head, before per-request content, so it does not invalidate the cache across turns, and any other request-prefix change is owned by the named consumer.
+Boot itself invalidates nothing in the request prefix.

 ## Known Limitations and Deferred Work
 
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits describe when this boot library is a poor fit or needs special care. They are current package constraints, not a task backlog.
+
 - **Bare package specifiers depend on Loader internals** — production bins need Loader's optional native helper; an in-process caller without it must use resolvable relative/file specifiers or provide its own module-resolution hook.
 - **Snapshot replay swapping is basename-specific** — only a config ending in `cordis.yml` or `cordis.yaml` maps to the sibling `cordis.snapshot.yml`; custom config names require caller-managed selection.
 - **Environment discovery is launch-scoped** — `loadLayeredEnv` reads only the invocation directory and Harness home once; it does not search parents or follow a workspace selected later. `loadEnv` remains the one-directory helper for non-product bins.
 - **A user patch replaces the whole matched config** — an id-targeted patch does not deep-merge, so a profile override restates the bundle fields it keeps.

+
+`renderConfigDump` output is a loadable YAML document whose `# ==` provenance comments and `!!js`-verbatim rendering serve the `--dump-config` diagnostic.

-供 [`dsh`](../../../apps/cli/README.zh.md) profile 共用的 Loader 启动粘合层，也用于 [Python 运行时 wheel](../../../python/README.zh.md)打包的 CLI。产品启动器负责 profile 组合与进程生命周期。直接配置 helper 服务于底层 embedder 与测试，不会定义另一个受支持的应用入口。
+## 概述
 
-| 导出 | 职责 |
+`dsh-app-boot` 是 `dsh` profile（包括 Python 运行时 wheel 所打包的 CLI）背后的共享 Loader 启动库。它加载环境层、组合 profile bundle 与 patch、启动每个插件，再返回运行中的应用，或指出失败插件与原因。产品应用使用 `dsh` launcher 而不发布单独 bin；直接配置 helper 只保留给低层嵌入方与测试。你还可以在启动前预览生效配置，按 profile 选择实时或仅启动时应用 patch，并让持有终端的应用在致命退出前恢复终端。

+## 使用本包
+
+用此包启动应用是一个小而显式的入口：你给它一个配置文件，它运行整个启动过程。本节说明你能做什么、能得到什么；每个结果背后的 helper 调用记录在下方可折叠的实现章节中。
+
+### 何时使用
+
+在实现共享 `dsh` launcher 或嵌入其低层启动 helper 时使用它。产品功能应放入 profile bundle，而不是新增应用 bin；只向已运行应用添加插件的代码直接挂载插件即可。
+
+### 启动应用
+
+你把配置文件交给入口，进程就会启动整个应用：加载环境层、应用 patch 与 profile、启动每个插件，并在应用运行后返回。在回放模式下，它会启动同级的 `cordis.snapshot.yml` 替代文件，使已记录的会话能够原样复现。最小的入口只需两次调用：
+
+```text
+installFailLoud('dsh')
+const ctx = await boot('dsh', resolveConfigPath(argv[2], process.env.DSH_SNAPSHOT))
+```
+
+有了这个入口，成功就是每个插件都已激活的运行中应用；失败绝不会悄无声息——一行带标签的信息点名失败的插件与阶段，进程以非零码退出。错误上报前会先拆卸应用上下文，因此不会留下半启动的残留。
+
+<a id="profiles"></a>
+### Profile
+
+profile 是同一套 dsh 安装提供不同应用界面的方式：`web`、`headless`、`acp`、`sdk` 与 `sdk-minimal` 从同一 launcher 启动不同组合。profile 位于 `$DSH_HOME/profiles/<name>`，由可安装 bundle、自身 `cordis.patch.yml` 与 `patchReload: live | startup` 组成；自定义 profile 省略 reload 策略时保留历史 `live` 默认值。随产品交付的 `web` 模板实时重载，其他随附模板只在启动时应用 patch。`sdk-minimal` 只列出自身的独立 bundle，其他模板保留 base 加模式 bundle 的栈。`dsh plugin` 创建自定义 profile；缺失 bundle 或未声明 patch 的 bundle 会让启动明确失败。
+
+你的机器本地偏好同样位于 harness home 中：
+
+- **`.env`**——你的普通环境层：调用目录的文件优先于 harness home 的文件，两者都低于继承环境。决定进程如何启动的变量（`PATH`、代理、`DSH_*`、`XDG_*` 等）会被文件拒绝：请改为导出。对于只想加载某个目录 `.env` 的非产品 bin，文件缺失不影响启动，文件无法加载时输出一行带标签的警告。
+- **`cordis.patch.yml`**——你的 tweak 层，应用在所有组合包层之后（先应用逐 profile 的文件，再应用 home 级文件，因此后者优先级更高）：替换某个条目的整个 config（重述你要保留的字段）、插入新条目，或在启动时插值 `!!js` 表达式。patch 指定的条目不存在时输出 stderr 警告；空文件或仅含注释的文件会导致启动失败——如需禁用该层，请改用 `[]`。
+
+带 `patchReload: live` 的 profile 会监视两份用户 patch 文件：有效编辑无需重启即可重新组合，被拒绝的编辑则让最后一个可用应用继续运行。`startup` profile 既不安装这些监视器，也不安装 launcher 的仅监视 HMR 回退。
+
+### 预览生效配置
+
+启动前，你可以打印应用将挂载的确切配置：dump 会以 `!!js` 表达式原样展示组合后的条目列表，并按注释分组标明每个源文件及其 patch 层，输出是一份可加载的 YAML 文档。未匹配到任何行的 patch 会连同其层标签一起报告；配置缺失、无法解析或字段无效都会使 dump 失败。
+
+### 启动失败时你会看到什么
+
+启动失败是一行带标签的信息加非零退出码——绝不是静默卡死或原始堆栈倾倒。信息会点名失败的插件；抛错的插件保留原始错误，从未启动的条目会连同它等待的服务一起报告。
+
+如果你的应用持有终端，它可以在进程退出前把终端交还，你的 shell 绝不会残留在 raw 模式。交还过程有界：卡住的清理只会延迟致命退出，而不会取消它。
+
+### 告诉 agent harness 所在位置
+
+当你的应用启动模型驱动的 agent 时，你可以告诉 agent DSH 实现代码 checkout 的位置：它得知该路径，也知道不得据此推断工作目录——它应使用 `pwd`。这条指示在系统提示词靠前位置出现一次。没有系统提示词服务的应用会跳过；开发环境中，重新加载系统提示词后它会消失，直至下次启动。

+## 理解实现
+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释上述结果如何实现，并指出实现它们的代码位置；这里的内容面向开发者，使用本包并不需要。
+
+### 设计说明
+
+- **与渠道无关的库。** 此包不包含 loader 钩子，也不提供开发模式接口；[`dsh` 应用](../../../apps/cli/README.zh.md) 持有自己的 Node 源码启动钩子，并在启动序列中使用这些 helper，构建后的消费方则使用普通 Node 包解析。
+- **两个 Loader builtin。** `mountRootInclude` 把 `cordis:include` 与 `cordis:group` 注册为 Loader builtin：group 行能把一个提供方与它的消费方放进同一个 `isolate` realm，而位于本工作区之外的 agent preset 无法按名称解析 `@deepseek-ai/cordis-plugin-group`。两者都通过宿主的模块管线加载，而非被包含树自身的说明符解析。
+- **Profile 模块后备机制。** 裸插件 specifier 由 Loader 从配置目录解析。普通 Node 会为安装依赖闭包中的每个包维护一个符号链接。打包可执行文件无法让操作系统符号链接进入 pkg 的 `/snapshot` 树，因此会按 Node ESM 条件读取已安装包的 export map，并写入重新导出虚拟模块 URL 的真实代理包。缺失 export 保持不可用，错误 export map 会让启动失败，跨进程 writer lock 则会在不暴露部分代理的情况下替换陈旧条目。
+- **单一 rejection 检查点。** `assertEntriesActivated` 把折入启动诊断的确切原因保持到下一个进程级 rejection 检查点可见，使 `installFailLoud` 能合并 Loader 的重复通知，而所有无关的未处理 rejection 仍然致命。
+- **两阶段失败标签。** `boot()` 区分 `host preparation failed`（`prepare` 在任何配置树条目挂载前抛出）与 `plugin tree failed to load`（此后的一切失败），并追加最深层插件错误的堆栈，使启动诊断保留原始激活错误，而不只是包装链。
+
+### Helper 行为
+
+每个导出各负责启动的一个阶段：配置解析与快照回放、分层环境加载、明确报错的保护机制、激活审计、patch 解析、根 include 挂载、配置 dump 渲染、活动 patch 监视、profile 组合，以及 harness 源码段落。各导出的约定在代码中，不在本 README——见 [`src/index.ts`](src/index.ts) 与 [`src/profile.ts`](src/profile.ts)。
+
+### 源码地图
+
+| 文件 | 职责 |
 |---|---|
-| `resolveConfigPath(path, snapshotMode, cwd?)` | 生成绝对配置路径；当 `snapshotMode === 'replay'` 时，把 basename 为 `cordis.yml`/`.yaml` 的文件替换为同级 `cordis.snapshot.yml` |
-| `loadEnv(binName, dir?, warn?)` | 加载已被 git 忽略的 `.env`（Node `process.loadEnvFile`）；文件不存在不影响启动，文件无法加载时输出一行带标签的警告（默认写入 stderr） |
-| `loadLayeredEnv(binName, cwd?, warn?)` | 构建产品 CLI（命令行界面）冻结的「继承环境 > 项目 `.env` > 用户 `.env`」快照，拒绝文件中的 bootstrap-only 变量，并在不替换继承值的前提下物化其余文件值 |
-| `installFailLoud(binName, proc?, release?)` | 将启动期或后续未处理的 Loader 拒绝转换为一行带标签的 stderr 消息并执行 `exit(1)`；两者之间会等待可选的 `release` 清理钩子（以 `FAIL_LOUD_RELEASE_TIMEOUT_MS` 为上限），使持有终端的界面能在退出前恢复终端；返回卸载函数 |
-| `FAIL_LOUD_RELEASE_TIMEOUT_MS` | `installFailLoud` 等待其 `release` 回调的时长；卡死的 disposer 只会延迟致命退出，而不会取消它 |
-| `assertEntriesLoaded(ctx, binName)` | 树结算后，如果其中存在已启用但没有 fiber 的条目，则抛出异常，并以 Cordis 启动故障的形式报告每个未解析插件的名称 |
-| `assertEntriesActivated(ctx, binName)` | 先执行 `assertEntriesLoaded` 检查，再在 Loader 结算后等待每个已启用配置项；抛出的错误包含每个失败插件的原始错误堆栈，或每个等待中插件尚未解析的服务 |
-| `loadOptionalPatches(binName, file)` | 解析一份可选的 patch 列表文件（即 profile 的 `cordis.patch.yml`）：其顶层是一个 YAML 数组，内容为 include 的 `PatchOptions`（按 id 定位的配置覆盖、`insert` 列表，允许 `!!js`）；文件不存在时返回 `undefined`，文件不可读、不可解析或内容不是数组时抛出异常 |
-| `loadOverlayPatches(binName, file)` | 解析必需的顶层 YAML 数组，其中包含与上文相同的 include `PatchOptions` 条目；插入行中的相对插件名以该文件所在目录解析，而用于断言已有行的 patch `name` 保持字面值；文件缺失也会抛出异常，因为该文件是调用方指名的 |
-| `mountRootInclude(ctx, absoluteConfigPath, patches?, bareModuleBaseUrl?)` | 注册静态导入的 `cordis:include` 与 `cordis:group` builtin，挂载 include，并保留用户 patch 层 HMR（热模块替换）使用的确切根配置项；可选模块基准会把裸包名锚定到已安装宿主，而相对名称仍以配置目录为基准 |
-| `watchUserPatches(ctx, options)` | 向现有 Cordis HMR 服务注册指名的 patch 文件；每次新增、变更或移除都会通过调用方的 `compose` 闭包（应用自有层围绕当前用户层）以事务方式重新组合完整 patch 列表，并返回异步 disposer |
-| `resolveProfileDir` / `initProfile` / `loadProfile` / `readProfileManifest` / `writeProfileManifest` / `resolveBundleDir` / `composeEntries` / `healProfilesModuleFallback` / `PROFILE_TEMPLATES` / `DEFAULT_PROFILE_BUNDLES` / `DEFAULT_PROFILE_PATCH_RELOAD` / `PROFILES_DIR` / `PROFILE_PATCH_FILENAME` | Profile 机制与 patch 文件生命周期（见 [Profile](#profiles)） |
-| `boot(binName, absoluteConfigPath, patches?, prepare?, bareModuleBaseUrl?)` | 创建根上下文，向 Loader `!!js` 配置表达式暴露 `dshHomePath(...segments)` 并安装 Loader，在配置树条目挂载前执行可选的宿主准备操作（`prepare` 可以使用 Loader，也可以提供由启动器拥有的上下文插槽），再挂载并等待 include 树结算，断言所有条目均已加载并激活，最后返回根上下文——失败时 dispose（资源释放）部分构造的上下文，并以带标签的错误 reject；可选模块基准与 `mountRootInclude` 的解析语义相同 |
-| `renderConfigDump(binName, absoluteConfigPath, layers, warn?)` | 使用 include 自己的解析器和补丁算法（`entryListSchema`/`applyEntryPatches`）离线合成基础配置与带标签的覆盖层，使结果与 `boot()` 挂载的内容一致，再渲染为 YAML，并原样保留 `!!js` 表达式；每段来源于同一文件且由相同补丁层修改的连续行之前都有一条 `# ==` 注释，标明该文件和这些补丁层，输出仍是一份可加载的文档；未匹配到行的补丁连同其层标签交给 `warn`（默认：一行 stderr），读取、解析或字段验证失败则抛出 |
-| `addHarnessSourceSection(ctx, sourceRoot)` | 添加全局 `harness:source` 提示词段落（顺序紧随 harness 身份、位于 persona 之前），告知 agent（智能体）DSH 实现代码 checkout 的磁盘路径，同时提醒它不得据此推断当前工作目录，而应使用 `pwd`；如果已启动树没有此项服务，则不执行操作并返回 `undefined`。这里的服务是 `systemPrompt`；该段落注册到它的 fiber，因此开发环境 HMR 重新加载系统提示词后，它会消失直至下次启动 |
-| `HARNESS_SOURCE_SECTION` | `'harness:source'` 段落名称，供 `addHarnessSourceSection` 注册使用 |
+| [`src/index.ts`](src/index.ts) | 启动 helper：配置解析、环境加载、会明确报错的保护机制、激活审计、patch 解析、配置 dump、harness 源码段落 |
+| [`src/profile.ts`](src/profile.ts) | profile 发现、初始化、组合包解析、模块后备机制 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；边界与回放测试覆盖其协议映射） |
 
-Loader 结算会在导入或生命周期失败时返回拒绝结果，并携带失败的配置项与阶段；`boot()` 会 dispose 部分构造的上下文，并用 bin 名称包装该失败。结算后遗留的配置项由独立审计处理：`assertEntriesLoaded` 将已启用却没有 fiber 的配置项转换为 rejection 并列出每个未解析插件；`assertEntriesActivated` 会显式等待每个失败的 fiber，把原始错误堆栈写入启动 rejection，并列出每个等待中配置项尚未解析的服务。抛出错误前，审计会通过一个进程级检查点标记这些 rejection 的确切原因，从而让 `installFailLoud` 将 Loader 的重复通知合并为一次，而所有无关的未处理 rejection 仍然致命。
+</details>
 
-Loader 并发挂载各个条目，因此当其他环节失败时，某个界面可能已经持有终端：此时不经过整棵树自身的拆卸就退出，会把 raw 模式、bracketed paste 和键盘协议残留在用户的 shell 上，而尚未返回的终端查询响应会在下一个提示符处显示为字面文本。配置树失败会经 `boot()` 结算：它先 dispose 部分构建的上下文（从而执行该界面自身的 shutdown），再抛出带标签的 rejection。对于 `boot()` 看不到的 rejection（插件游离的异步工作在挂载期间或挂载完成后失败），持有终端的 bin 会传入 `release`，在提交退出前 dispose 整棵树；`dsh` 在 `boot()` 的 `prepare` 回调中捕获根上下文，而不是取其返回值，使该回调覆盖整个挂载窗口。release 执行期间，处理函数保持注册并处于锁定状态：被报告的始终是第一个 rejection，后续拒绝（包括拆卸自身产生的拒绝）会被忽略，而不会变成未捕获错误、在拆卸中途杀死进程。
+-----
 
-`cordis:group` 与 `cordis:include` 一并注册，使一份组装能把一个提供方与它的消费方放进同一个 `isolate` realm。两者都通过宿主的模块管线加载，而非被包含树自身的说明符解析，这正是让本工作区之外的组装——放在 harness home 下的 agent preset——能够使用 group 行的原因。
+<a id="further-exploration"></a>
+## 进一步探索
 
-配置中的裸插件 specifier（`@deepseek-ai/dsh-*`、npm 包）通过 Cordis Loader 的内部模块 loader 解析。默认情况下，它们从配置目录解析；封闭运行时会向 `boot` 或 `mountRootInclude` 传入 `bareModuleBaseUrl`，使已安装包树保持权威，即使配置位于另一个 Node 项目中也不受遮蔽。相对 specifier 始终以配置目录为基准解析。仓库 bin 会安装 Loader 的可选对等依赖（peer dependency） `node-addon-require-builtin`；外部调用方必须提供该组件，或者把插件安装到普通 Node import 解析可以找到的位置。构建后的 `dsh-app-boot` 产物内嵌静态挂载的 Include 实现，但仍将 Loader 保持为外部依赖，因此 include 树与宿主会绑定到同一个 Loader peer。`pnpm dsh` 源码路径还会将 manifest（元数据清单）声明的 workspace 包映射到其 TypeScript 源码；其配置门禁要求每个随附的原始／Web 裸插件都出现在解析所用 manifest 的 `dependencies` 中。
+当包级约定不够用时阅读以下页面。它们从共享启动机制逐步进入组合模型及其背后的决策证据。
 
-此包不包含 loader 钩子，也不提供开发模式接口。[`dsh` 应用](../../../apps/cli/README.zh.md) 持有自己的 Node 源码启动钩子，并在启动序列中使用这些 helper；构建后的消费方仍使用普通 Node 包解析。
+- [Cordis 入门](../../../docs/cordis-primer.zh.md)——Loader、`!!js` 配置表达式，以及 include/group 语义。
+- [dsh 应用](../../../apps/cli/README.zh.md)——消费这些 helper 的 `dsh` bin。
+- [dsh-cmdline](../cmdline/README.zh.md)——各 bin 使用的启动器到应用命令行交接。
+- [Profile 组合包](../../bundle/README.zh.md)——组合进 `dsh --profile` 的可安装 patch 层。
+- [dsh-home-paths](../../util/home-paths/README.zh.md)——harness home 解析器（`resolveDshHome`）。
+- [配置来源归属](../../../.agents/notes/implemented/architecture/2026-08-04-configuration-source-ownership.zh.md)——被发现的文件为何不得决定 bootstrap 行为。
+- [Profile 插件组合包](../../../.agents/notes/implemented/architecture/2026-08-05-profile-plugin-bundles.zh.md)——profile 与组合包组合设计。
 
-## Profiles
-
-profile 是位于 `$DSH_HOME/profiles/<name>` 下的目录（harness home 由 [`resolveDshHome`](../../util/home-paths/README.zh.md) 解析：先取 `$DSH_HOME`，否则取 `~/.dsh`），其中包含一个 `package.json`（树外插件 `dependencies`，加上 profile manifest `dsh.profile` 及其有序的 `bundles` 层列表和 `patchReload: live | startup`）和用户自己的 `cordis.patch.yml`。`live` 会在启动后监视 profile 与 home 级 patch 文件；`startup` 只应用每层一次。缺失值为自定义 profile 保留历史 `live` 默认值。组合包是在 manifest 中声明 `"dsh": { "bundle": { "patch": "./cordis.patch.yml" } }` 的 npm 包；`loadProfile` 以双锚点解析每个 `dsh.profile.bundles` 名称（先从 dsh 安装目录，再从 profile 目录），列出的包若没有组合包声明则明确报错。`composeEntries` 通过 include 自己的 `applyEntryPatches` 在空条目列表之上应用各 patch 层，因此组合、标志推导和配置 dump 绝不会与实际启动内容发生偏离。`healProfilesModuleFallback` 维护扁平的 `$DSH_HOME/profiles/node_modules` 目录。普通 Node 为安装依赖闭包中的每个包写入一个符号链接；pkg 可执行程序则直接从每个已安装 manifest 中按 Node ESM import 条件解析实际存在的显式 exports，并写入重新导出虚拟模块 URL 的真实代理包，因为操作系统符号链接无法进入 pkg 的 `/snapshot` 树。安装包中不存在的 export 目标保持不可用，但不阻塞其他 exports；格式错误的 exports map 会导致启动失败。只有可执行入口或类型声明入口而没有模块入口的包不会生成代理。完整且匹配的 generation 不会获取写入锁。缺失或过期的配置项会获取跨进程锁、重新检查完整 generation，并在不暴露半成品代理的前提下修复；两种载体都会替换另一种载体留下的受管条目。两种形式都使 profile 插件可以通过 Node 常规的逐级向上查找解析安装包，并让外部插件 peer 共用一个模块实例。`PROFILE_TEMPLATES` 首次使用时以实时重载初始化 `web`，以仅启动时 patch 初始化 `headless`／`sdk`／`sdk-minimal`／`acp`；`sdk-minimal` 只列出自己的独立组合包，其他模板保留 base 加模式层的组合。其他名称在通过 `dsh plugin` 由 `initProfile` 创建前都会明确报错。`loadProfile` 会把安装自有的精确组合包元组和缺失的重载选择规范化为随附模板，同时保留每个显式重载选择和 manifest 中其他所有字段；组合包一旦有任何额外、缺失或重排，列表就归用户所有并保持不变。
-
-用户级的机器本地偏好同样位于 harness home 中：
-
-- **`.env`**：产品 CLI 的普通环境层；调用目录的文件优先于 harness home 的文件，两者都低于继承环境。`loadLayeredEnv` 记录每个值的来源，按不区分大小写的方式拒绝 [bootstrap-only 文件变量](../../../.agents/notes/implemented/architecture/2026-08-04-configuration-source-ownership.zh.md#decision)，并把其余值物化进 `process.env`，供 Loader 表达式和第三方库使用。受管凭据另存于 [`.credentials.yaml`](../../credentials/credentials-local/README.zh.md)；留在任一 `.env` 中的凭据仍是低优先级后备值。
-- **`cordis.patch.yml`**（home 级）与 **`profiles/<name>/cordis.patch.yml`**：用户 patch 层，应用在所有组合包层之后（先应用逐 profile 的文件，再应用 home 级文件，因此后者优先级更高）：按 id 定位的 patch 会替换对应条目的整个 `config`（未改字段也要重述），`insert` 会添加条目，`!!js` 表达式则在挂载时插值。如果 patch 指定的条目 id 不在组合后的树中，则输出一条 stderr 警告。空文件或仅含注释的文件会抛出异常（其解析结果为空，而不是列表）；如需禁用该层，请使用 `[]`。
-
-每个 `patchReload: live` profile 都通过 `watchUserPatches` 保持两个用户 patch 文件实时生效。即使文件或其直接父目录不存在，watcher 仍会监视确切路径；它会串行处理突发变更，并按调用方的层次顺序重新组合用户 patch（组合包层在下、overlay 在上）。读取失败、解析失败或 Loader 候选被拒时，最后一个可用树会继续运行；HMR 服务记录错误后广播 `hmr/config-update-failed(filename, Error)`，并隔离观察方失败。上下文 dispose 时会关闭 watcher，并等待进行中的刷新结束。`startup` profile 不安装这些 watcher，也不安装启动器的仅监视 HMR fallback。

 ## 模型体验

-The command line a dsh launcher hands to the app it boots. The launcher parses only its own flags (`--profile`, `--patch`, the config dumps) and hands **everything after them** to the tree verbatim, so an app owns its flag family, its `--help` text, and its parse errors instead of the launcher knowing them.
+## Summary
 
-## The launcher values
+`dsh-cmdline` lets your app own its command line: the launcher keeps only its own flags (`--profile`, `--patch`, the config dumps) and passes everything after them to your app verbatim, so your app decides its flags, its `--help` text, and its parse errors. Values you parse from those arguments win over any default written in the config, without writing anything back. Your app also gets a bounded way to ask for process exit, wired to the launcher's shutdown. Use it when you write an app bin that accepts its own flags; it adds no prompt, schema, or model-facing surface of its own.
 
-A launcher calls `provideCmdline(ctx, host)` before any tree entry mounts, which provides:
+## Table of Contents
 
-- `ctx.cmdlineArgs` — the invocation's inner arguments. `get()` is the whole interface, and it returns a snapshot: `dsh --profile tui --resume abc` yields `['--resume', 'abc']`.
-- `ctx.appExit` — a bounded process-exit request, wired to the launcher's shutdown controller.
-- `ctx.appReady` — the launcher's successful-startup signal. It commits only after the Loader tree and launcher-owned setup succeed; failed or externally terminated startup never calls pending listeners.

-An embedding host with no command line provides an empty list; that is the honest answer, not a missing value.
+-----
 
-`exitOnStdinEnd(ctx, label)` binds a successfully accepted stdio application's EOF to `ctx.appExit(0)` after `ctx.appReady` commits. It never reads or resumes stdin, so the protocol transport receives bytes buffered before it mounts. A startup rejection wins over a racing EOF, an already-ended stream still requests shutdown after successful startup, and the calling plugin's fiber removes both pending listeners. An app calls it inside the same command action that publishes its startup service, so help and rejected arguments leave the transport and EOF lifecycle unmounted.
+<a id="use-this-package"></a>
+## Use this package
 
-## Ordinary providers and injected config
+Your app reads the invocation's inner arguments at startup, and any number of its plugins can use them. The common path: a startup plugin reads the arguments, parses them, and publishes the parsed values; other rows configure themselves from those values.
 
-Any app plugin may inject `cmdlineArgs`, parse it, and publish an ordinary app-owned service. `parseCmdline(ctx, program)` is only a commander adapter; the program's own action owns validation and the published service:
+### The launcher values
 
-```ts ignore
-export const name = 'web-startup'
-export const inject = ['cmdlineArgs']
+The launcher makes three things available to your app:
 
-export function apply(ctx: Context): void {
-  const program = webCommand()
-  program.action(() => ctx.provide('webStartup', webValuesFrom(program)))
-  parseCmdline(ctx, program)
-}
-```
+- `ctx.cmdlineArgs` — the inner arguments of your invocation. Reading them returns an immutable snapshot and never consumes or changes them: `dsh --profile tui --resume abc` gives your app `['--resume', 'abc']`.
+- `ctx.appExit` — a way to ask the process to exit once the tree has shut down, wired to the launcher's shutdown controller.
+- `ctx.appReady` — the successful-startup signal, committed only after the Loader tree and launcher-owned setup succeed.
 
-Its Loader row carries no launcher marker or special kind:
+An app launched with no arguments sees an empty list — that is the honest answer, not a missing value.
+
+`exitOnStdinEnd(ctx, label)` binds a successfully started stdio application's EOF to `ctx.appExit(0)`. It never reads or resumes stdin, so a protocol transport receives bytes buffered before it mounts; startup rejection wins over a racing EOF, and the owning fiber removes both pending listeners.
+
+### Parsing your flags
+
+You bring your own commander program: declare your flags and your actions, and the package runs it against the inner arguments. Your action is the only place validation happens, and it publishes whatever your rows need. The plugin's Loader row carries no special marker:
 
 ```yaml
 - id: web-startup
   name: '@deepseek-ai/dsh-web-app/startup'
 ```
 
-Every row configured from those values uses ordinary service injection and direct lazy config access:
+Rows configured from the parsed values inject the published service and read it directly in their config:
 
 ```yaml
 - id: webserver
@@ -49,21 +59,67 @@ Every row configured from those values uses ordinary service injection and direc
     port: !!js ctx.webStartup.port ?? 3080
 ```
 
-`parseCmdline` refuses at load a program in which no command declares an action, routes every command's exit and output through the launcher (commander copies those settings into subcommands only at registration), and parses the immutable arguments; commander runs the invoked command's synchronous action on success. An action rejects an invalid invocation with `program.error(...)` — before publishing, since statements ahead of the rejection have already run. On `--help`, `--version`, a parse error, or that rejection, the helper writes commander's text and requests exit; the provider publishes nothing, so dependent rows never activate.
+The outcomes: `dsh --profile web --port 8080` starts the server on port 8080 even when the config says 3080, because the flag wins. `--help` prints your app's help and exits 0 without starting anything; a rejected value (for example a non-numeric port) prints your error and exits nonzero, and no row that depends on the parsed values ever starts.
 
-### How injection orders config
+### How flags beat config values
 
-Loader defers a row's `!!js` interpolation until that row's declared injections are active, then evaluates against the row's plugin context. The example above can therefore read `ctx.webStartup` directly: Cordis has already populated that injected service before Loader asks for `webserver`'s config. Include trees preserve nested expression nodes until each target row reaches this point. Provider replacement and live patch reload repeat interpolation against the current injected services, so a launch flag cannot be silently reset.
+The value written beside a `!!js` expression is the fallback: the flag wins when present, the written value is used otherwise. Resolution happens once at startup, after your parser ran, so a flag is never silently reset by a later config reload.
 
-### Shared immutable arguments
+### Reading the same arguments from several plugins
 
-`get()` does not consume or mutate argv. Multiple plugins can parse the same snapshot and independently provide services. The launcher does not inspect the composition for a command-line owner; a profile with no reader simply ignores its app arguments.
+Any number of plugins can read the same arguments — reading never consumes them — and each can parse what it needs and publish its own values. The launcher does not decide who owns the command line: an app with no reader ignores its arguments.
 
-An out-of-tree plugin brings its own commander copy, so commander's control-flow errors are detected structurally rather than by class identity; an identity check would rethrow a printed help as a fatal load failure.
+Apps built outside this repository behave the same way: their `--help` prints and exits instead of crashing, even though they carry their own commander copy.

+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the outcomes above are realized and points at the code that realizes them; everything here is developer-facing and not needed to use the package.
+
+### Design notes
+
+- **Launcher facts, not config.** `cmdlineArgs` and `appExit` are provided on the host context before the tree mounts; they are not Loader rows, so no composition owns or overrides them.
+- **Positional split.** The launcher recognizes no app row: the first token after its own flags starts the app's arguments, so the app owns its flag family, its `--help` text, and its parse errors.
+- **Structural error detection.** `isCommanderError` reads commander's error code prefix instead of using `instanceof`, because an out-of-tree plugin brings its own commander copy whose `CommanderError` identity differs; `configureExitAndOutput` walks every subcommand because commander copies exit and output settings only at registration.
+- **Injectable output streams.** `internals` holds the output streams so tests can capture commander's text without touching the process.
+
+### Parsing contract
+
+The parse path is one small family with two owners: `provideCmdline` freezes the host arguments and provides `cmdlineArgs` and `appExit` before any tree entry mounts, and `parseCmdline` runs your commander program against the immutable arguments, routing every command's help, version, and error output through the launcher. A rejected value, `--help`, or `--version` prints commander's text and requests `ctx.appExit` without publishing anything, so dependent rows never activate; Loader defers each row's `!!js` interpolation until its declared injections are active. Per-export contracts live in the code, not this README — see [`src/index.ts`](src/index.ts).

 ## Known Limitations and Deferred Work
 
-- **Launcher flags must precede app arguments.** The split is positional: the first token the launcher does not recognize starts the inner arguments, so `--patch` placed after an app flag belongs to the app. The launcher's parser consumes one `--`, so an app argument that must survive as a literal `--` needs `-- --`.
-- **An app-owned service has no statically declared provider.** Consumer rows name it through ordinary injection; a bundle that omits its provider fails at settlement with pending entries naming the service rather than at load.
-- **A user patch that replaces a row's whole `config` drops its expressions.** A flag beats the value written beside it, not a literal a user wrote in place of the expression; keeping the expression is what keeps the flag winning.

+#### Open: parser surface
+
+`parseCmdline` is a commander adapter, not a command-line framework: help, version, and error output follow commander's formatting, and the exit/output routing assumes commander's control-flow model.

-- `ctx.appReady`：启动器的成功启动信号。只有 Loader 树和启动器自身的设置都成功后才会提交；启动失败或被外部终止时，待处理 listener 永远不会被调用。

-Loader 会把一行的 `!!js` 插值推迟到该行声明的注入全部激活之后，再基于该行的插件上下文求值。所以上例可以直接读取 `ctx.webStartup`：Loader 索取 `webserver` 的配置之前，Cordis 已经填入了这个注入服务。Include 树会保留嵌套表达式节点，直到各个目标行到达这一时点。提供方替换与活动 patch 重载都会针对当前注入服务重新插值，因此启动 flag 不会被悄悄重置。

+- **启动器事实，而非配置。** `cmdlineArgs` 与 `appExit` 在树挂载前提供到宿主上下文上；它们不是 Loader 行，因此没有任何组合持有或覆盖它们。
+- **按位置切分。** 启动器不认识任何应用行：自身 flag 之后的第一个 token 就是应用参数的起点，因此 flag 家族、`--help` 文本与解析错误都由应用自己持有。
+- **结构化错误识别。** `isCommanderError` 读取 commander 的错误码前缀，而不是用 `instanceof`，因为树外插件会带来自己的一份 commander 副本，其 `CommanderError` 身份不同；`configureExitAndOutput` 会遍历每个子命令，因为 commander 只在注册时复制退出与输出设置。
+- **可注入的输出流。** `internals` 持有输出流，使测试无需触碰进程即可捕获 commander 的文本。
+
+### 解析约定
+
+解析路径是一个只有两个所有者的小家族：`provideCmdline` 冻结宿主参数，并在任何配置树条目挂载前提供 `cmdlineArgs` 与 `appExit`；`parseCmdline` 针对不可变参数运行你的 commander program，把每个命令的 help、version 与错误输出都接到启动器上。被拒绝的值、`--help` 或 `--version` 会打印 commander 文本并请求 `ctx.appExit`，且不发布任何内容，因此依赖行绝不会激活；Loader 会把每行的 `!!js` 插值推迟到该行声明的注入全部激活之后。各导出的约定在代码中，不在本 README——见 [`src/index.ts`](src/index.ts)。

 # bundle/ — profile plugin bundles
 
 English | [中文](README.zh.md)
 
-Profile bundles: npm packages whose manifest declares `"dsh": { "bundle": { "patch": "./cordis.patch.yml" } }`, making them installable patch layers for `dsh --profile` compositions ([profile contract](../boot/app-boot/README.md#profiles)). A bundle's substance is its patch list; some also ship runtime glue plugins their patch mounts.
+## Summary
 
-The manifest declaration, not this directory, defines Bundle identity. Domain packages can carry their own optional Profile layer; the [Codex and Claude Code subagent packages](../subagent/README.md) are directly installable examples.
+This group maps the installable patch layers used by `dsh --profile`. Each package declares `dsh.bundle.patch`; the launcher stacks those patch documents to assemble a named profile. The `web`, `headless`, `acp`, and `sdk` profiles build on `dsh-base`, while `sdk-minimal` supplies its complete tree in one bundle. Domain packages can declare additional layers outside this directory.

 [English](README.md) | 中文
 
-Profile 组合包：在 manifest（元数据清单）中声明 `"dsh": { "bundle": { "patch": "./cordis.patch.yml" } }` 的 npm 包，因此可作为 patch 层安装进 `dsh --profile` 组合（[profile 约定](../boot/app-boot/README.zh.md#profiles)）。组合包的实体是它的 patch 列表；有些组合包还附带由其 patch 挂载的运行时粘合插件。
+## 概述
 
-Bundle 身份由 manifest 声明决定，而不是由本目录决定。领域包可以携带自己的可选 Profile 层；[Codex 与 Claude Code subagent 包](../subagent/README.zh.md)就是可直接安装的例子。
+本组列出 `dsh --profile` 使用的可安装 patch 层。每个包都声明 `dsh.bundle.patch`；启动器会叠放这些 patch 文档来组装具名 profile。`web`、`headless`、`acp` 与 `sdk` profile 以 `dsh-base` 为基础，`sdk-minimal` 则由一个 bundle 提供完整配置树。领域包也可以在本目录之外声明附加层。

 # `@deepseek-ai/dsh-acp-app`
 
 English | [中文](README.zh.md)
 
+## Summary
+
 The automation-only ACP stdio application as a `dsh` profile bundle over [`dsh-base`](../base/README.md). It inherits the base's disabled module-HMR policy; its patch sets the coding-agent persona and default model route, mounts an app-owned zero-option command provider, and starts [`dsh-acp`](../../acp/acp/README.md) only after that provider accepts the invocation. `dsh --profile acp --help` therefore writes help and exits without claiming stdin or stdout.

+## Use this package
+
 The startup provider binds stdin EOF to the launcher's bounded successful shutdown. ACP connection close, SIGINT, and SIGTERM drain the bridge-owned agents and the root profile tree before exit. Stdout is reserved for newline-delimited ACP JSON-RPC frames. The bundle disables model-generated session titles because ACP exposes no title surface; deterministic fallback titles remain durable without an auxiliary model request. The inherited projection cache checkpoints ACP-created sessions for later consumers; its durability barrier flushes each covered log prefix before publishing the cache row and may split otherwise coalesced JSONL runs. A deployment selects a different complete composition through profile bundles and patch files, not another app bin.
 
 The shipped row creates sessions with `deepseek-official` and `deepseek-v4-flash`; a later patch can replace that row's complete config. The base profile owns adapters, tools, persistence, policy, settings, credentials, and the per-session workspace supplied by the ACP client.
 
+-----
+
+<a id="standard-automation-workflow"></a>
 ## Standard automation workflow
 
 An ACP v1 SDK client initializes `dsh --profile acp`, creates a session with an absolute `cwd` and optional standard stdio/HTTP MCP declarations, chooses an advertised `model` or `reasoning_effort`, prompts while observing standard semantic updates, then calls `session/close`. Another process can use `session/list` and `session/resume` against the same profile persistence root; resume reconnects the MCP declarations supplied by that request and does not replay history.
 
 The complete supported method matrix, MCP trust model, update mapping, and stop reasons live in the [`dsh-acp` protocol contract](../../acp/acp/README.md#standard-acp-v1-surface). This profile adds no private method, capability, `_meta`, environment variable, or transport field. The keyless control-surface conformance test drives the real profile through the public ACP SDK.

 - **A profile can omit the ACP bridge** — a custom ACP launch profile must retain this bundle or another `dsh-acp` row; otherwise no peer answers the client.
 - **User plugins can violate stdout purity** — profile and per-launch patches are trusted application composition. The shipped bundle writes no non-protocol stdout, but it cannot contain an arbitrary inserted plugin.
 - **Configuration changes require restart** — the shipped `acp` profile uses `patchReload: startup` so one stdio connection never observes a replacement bridge or Agent dependency.

 [English](README.md) | 中文
 
+## 概述
+
 以 [`dsh-base`](../base/README.zh.md) 为基础的 automation-only ACP stdio 应用 `dsh` profile 组合包。它继承 base 默认禁用模块 HMR（热模块替换）的策略；其 patch 设置 coding agent（编程智能体）persona 与默认模型路由、挂载应用自有的零选项命令提供方，并且只在该提供方接受调用后启动 [`dsh-acp`](../../acp/acp/README.zh.md)。因此，`dsh --profile acp --help` 会写出 help 并退出，不会占用 stdin 或 stdout。

+## 使用本包
+
 启动提供方把 stdin EOF 绑定到启动器的有界成功关闭。ACP 连接关闭、SIGINT 与 SIGTERM 会在退出前排空 bridge 自有 agent 以及根 profile 树。Stdout 仅保留给换行分隔的 ACP JSON-RPC frame。ACP 不提供 title 表层，因此本组合包禁用模型生成的 session title；确定性的 fallback title 仍会持久化，但不发起辅助模型请求。继承的投影缓存会为 ACP 创建的会话写入检查点，供后续消费方使用；其持久性屏障会在发布缓存行前 flush 所覆盖的日志前缀，因此可能拆分原本会合并的 JSONL 行。部署方通过 profile 组合包与 patch 文件选择另一套完整组合，而不是使用另一个 app bin。
 
 随附配置项使用 `deepseek-official` 与 `deepseek-v4-flash` 创建 session；后续 patch 可以替换该配置项的完整 config。base profile 负责适配器、工具、持久化、策略、settings 与 credentials；ACP client 为每个 session 提供工作区。

+
+<a id="standard-automation-workflow"></a>
 ## 标准自动化工作流
 
 ACP v1 SDK 客户端先初始化 `dsh --profile acp`，再用绝对 `cwd` 与可选的标准 stdio／HTTP MCP 声明创建 session，选择公开的 `model` 或 `reasoning_effort`，在观察标准语义更新的同时提交提示词，最后调用 `session/close`。另一个进程可以针对同一个 profile 持久化根目录使用 `session/list` 与 `session/resume`；resume 会重新连接该请求提供的 MCP 声明，但不会重放历史。
 
 完整的受支持方法矩阵、MCP 信任模型、更新映射与停止原因见 [`dsh-acp` 协议约定](../../acp/acp/README.zh.md#standard-acp-v1-surface)。该 profile 不增加私有方法、能力、`_meta`、环境变量或传输字段。免密钥控制面一致性测试通过公开 ACP SDK 驱动真实 profile。

 English | [中文](README.zh.md)
 
-The shared dsh core as a profile bundle: [`cordis.patch.yml`](cordis.patch.yml) inserts every base plugin row — model adapters, the shared [`agent-default-model`](../../core/agent-default-model/README.md) selection, tools, persistence, policy, settings/credentials, telemetry, and the core spawn/fork subagent providers — over the empty profile root, as the first layer of each base-backed profile's `dsh.profile.bundles` list. The standalone [`sdk-minimal`](../sdk-minimal/README.md) profile deliberately does not include this bundle. The optional Codex and Claude Code providers stay outside this package and its production dependency closure; a Profile installs either [product provider Bundle](../../subagent/README.md) only when needed. The default `@deepseek-ai/dsh` production closure therefore includes neither product provider, the Claude Agent SDK, nor the Codex wrapper and platform payloads. Later bundle layers (e.g. [`dsh-web-app`](../web-app/README.md)) and the user's profile `cordis.patch.yml` override these rows by id; a patch replaces a row's whole `config`, so mode-specific values live in mode bundles, not here. The package has no runtime API; the profile composer resolves the patch through the `dsh.bundle.patch` manifest field, never through code.
+## Summary
 
-The base module-HMR row is disabled. A profile with a tested source-module reload lifecycle enables that row explicitly; `patchReload: live` config watching is independent and uses the launcher's watch-only fallback while module HMR remains disabled.
+Every base-backed `dsh --profile` surface runs on `dsh-base`, so those surfaces share a model connection, the full tool set, durable session history, and workspace safety defaults. The shipped `sdk-minimal` profile deliberately uses a complete standalone tree instead. You rarely touch this bundle directly — shipped base-backed profiles already include it, and a custom base-backed profile names it first. When you need different defaults, change your profile patch or add a later bundle; this package is not a library you import.
 
-The patch gates both shell stacks by platform on its own rows: `bash-sandbox`/`tool-bash` carry `disabled: !!js process.platform === 'win32'` (bash has no Windows runner), and their twins `pwsh-sandbox`/`tool-pwsh` mount on win32 only with the inverted expression — one shared patch file, exactly one shell stack per host. The permission surface stays exactly as on POSIX: `sandbox`/`sandbox-policy` enforce the file-effect policy through the Windows ACL restricted-token runner (the win32 chain of `dsh-sandbox-local` → `@deepseek-ai/dsh-sandbox-windows-acl`), the permission switcher and the approval service run unchanged, and `fs-sandbox` keeps fencing `ctx.fs` writes — mounting `dsh-fs-local` alongside it would double-register `ctx.fs` and fail the load. A Windows host that prefers the unconfined local pwsh executor or full access overrides these rows through its profile or home `cordis.patch.yml` (the bash-restore recipe must be complete: disable `pwsh-sandbox`/`tool-pwsh` AND re-enable `bash-sandbox`/`tool-bash` — both executor families register the same `bash` service, so an incomplete recipe fails loud at load). POSIX hosts see the pwsh rows disabled.

+## Use this package
+
+You get the dsh core automatically: the shipped `web` and `headless` profiles already include it, and a custom profile names it as its first bundle. After that, everything works with no further configuration.
+
+### A minimal custom profile
+
+To build a profile on the shared core, create a profile with a `package.json` that names `@deepseek-ai/dsh-base` first:
+
+```json
+{
+  "name": "my-profile",
+  "private": true,
+  "dsh": {
+    "profile": {
+      "bundles": ["@deepseek-ai/dsh-base"]
+    }
+  }
+}
+```
+
+Run `dsh --profile my-profile "your task"` and you get a working agent with model access, tools, persistence, and the default permission policy. The shipped `web` and `headless` profiles are created for you on first use. To add more bundles, run `dsh plugin --profile <name> add <package>`; in-box bundles resolve from the dsh installation. The profile contract is documented in the [app-boot profile section](../../boot/app-boot/README.md).
+
+### What you get
+
+Out of the box, every profile built on this core provides: a DeepSeek model connection (the provider and model are configurable, and you can enable extra providers from your settings), the full tool set — file editing, shell commands, web search, subagents, task and goal tracking — durable sessions that survive restarts, and the default permission policy that confines file writes to your workspace and asks before risky actions. Telemetry stays off unless you opt in.
+
+### Shell tools per platform
+
+On macOS and Linux you get the bash shell tools; on Windows you get the PowerShell twins instead, so exactly one shell stack is available per machine. The safety behavior is identical on every platform. A Windows host that prefers the unconfined PowerShell executor can switch the shell rows in its profile patch — the switch must disable both PowerShell rows and re-enable both bash rows, otherwise the profile fails to load.
+
+### Changing the defaults
+
+To change what a profile built on this core provides — a different default model, a stricter permission mode, extra or fewer tools — edit your profile's `cordis.patch.yml` or add a later bundle. Each patch entry replaces the target's whole configuration, so restate every setting you want to keep. Keep the sandboxed filesystem provider as the single file-write path: adding the plain filesystem provider on top of it makes the profile fail to load.
+
+-----
+
+<a id="understand-the-implementation"></a>
+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+The bundle is a static patch document: one `insert` list applied over the empty profile root. It mounts no service, emits no events, and holds no mutable state; each inserted row's package owns that row's behavior and invariants.
+
+### Composition mechanics
+
+A patch replaces the targeted row's whole `config` rather than merging into it. Later bundle layers and the user's profile `cordis.patch.yml` override rows by id, with the last write winning per row. Rows whose value differs by mode do not live here: each mode bundle restates its complete configuration, keeping any single row down to one bundle layer plus the user's. The full row set and its rationale are documented inline in [`cordis.patch.yml`](cordis.patch.yml); the [generated composition graph](../../../apps/cli/composition.md) renders it.
+
+### Platform gating
+
+The patch gates the two shell stacks by platform on its own rows: `bash-sandbox` and `tool-bash` carry `disabled: !!js process.platform === 'win32'`, and their twins `pwsh-sandbox` and `tool-pwsh` mount on win32 only with the inverted expression. The permission surface stays identical to POSIX: the sandbox policy executes the same file-effect policy through the Windows ACL restricted-token runner (`dsh-sandbox-local` → `@deepseek-ai/dsh-sandbox-windows-acl`), and `fs-sandbox` keeps fencing `ctx.fs` writes — mounting `dsh-fs-local` alongside it would double-register `ctx.fs` and fail the load.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`cordis.patch.yml`](cordis.patch.yml) | The bundle substance: the base plugin rows, with per-row rationale as inline comments |
+| [`src/index.ts`](src/index.ts) | Package entry; carries no runtime API |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion: no runtime invariant; each inserted row's package owns its invariants |
+| [`tests/base.spec.ts`](tests/base.spec.ts) | Manifest declaration and platform-gating checks |
+
+### Invariant ownership
+
+The invariant companion registers an empty installer because the package is a static patch-list carrier: each inserted row's own package carries that row's invariants, and the bundle owns no mutable relation to check.

 ## Model Experience
 
-Indirectly, through the inserted rows: this bundle selects the shipped persona-less prompt base, tool set, and DeepSeek adapter that mode bundles specialize, and contributes no model-visible text of its own.
+Indirectly, through each inserted row's package, which owns that row's model-facing behavior.
 
 #### KV Cache effect
 
-None directly; each inserted row's package owns its effect.
+The bundle itself adds no request prefix; each inserted row's package owns any cache effect.
 
 ## Known Limitations and Deferred Work
 
-- **A patch replaces whole row configs** — profile overrides must restate every field a row keeps; there is no deep-merge layer.
-- **The Windows temp grant is a private per-session subdirectory** — `workspace-write` confines writes to the workspace plus the session's own temp subdirectory (`<temp>\dsh-<hash>`, TMP/TEMP rewritten for confined children); `read-only` grants nothing. See `@deepseek-ai/dsh-sandbox-windows-acl`.
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits tell you when the core needs extra care or where an override must go. They are current package constraints, not a general comparison or a task backlog.
+
+- **Overrides replace whole settings blocks** — a patch entry replaces the target's entire configuration, so your override must restate every setting you want to keep; nothing merges automatically.
+- **Per-surface settings belong to the surface's bundle** — a default that differs between the web GUI and headless mode lives in that surface's bundle, not in the shared core.
+- **Windows temp grants are private per-session subdirectories** — `workspace-write` confines writes to the workspace plus the session's own temp subdirectory (`<temp>\dsh-<hash>`, TMP/TEMP rewritten for confined children); `read-only` grants nothing. See `@deepseek-ai/dsh-sandbox-windows-acl`.
+- **Adding the plain filesystem provider on top of the sandboxed one fails the profile** — the two register the same service, so the profile refuses to load; use one or the other.

-以 profile 组合包形式交付的共享 dsh 核心：[`cordis.patch.yml`](cordis.patch.yml) 在空的 profile 根之上插入全部基础插件行——模型适配器、共享的 [`agent-default-model`](../../core/agent-default-model/README.zh.md) 选择、工具、持久化、策略、settings／credentials、遥测与核心 spawn／fork subagent provider——作为每个基于 base 的 profile 的 `dsh.profile.bundles` 列表中的第一层。独立的 [`sdk-minimal`](../sdk-minimal/README.zh.md) profile 刻意不包含本组合包。可选的 Codex 与 Claude Code provider 不属于本包及其生产依赖闭包；Profile 仅在需要时安装任一[产品 provider Bundle](../../subagent/README.zh.md)。因此，默认的 `@deepseek-ai/dsh` 生产依赖闭包既不包含任一产品 provider、Claude Agent SDK，也不包含 Codex wrapper 及其平台载荷。后续的组合包层（例如 [`dsh-web-app`](../web-app/README.zh.md)）和用户 profile 的 `cordis.patch.yml` 按 id 覆盖这些行；patch 会替换目标行的整个 `config`，因此模式专属的值放在各模式组合包中，而不是这里。该包没有运行时 API；profile 组合器通过 manifest（元数据清单）的 `dsh.bundle.patch` 字段解析 patch，绝不通过代码。
+## 概述
 
-base 的模块 HMR 配置项默认禁用。具有经过验证的源码模块重载生命周期的 profile 必须显式启用该配置项；`patchReload: live` 配置监视与之独立，在模块 HMR 保持禁用时使用启动器的仅监视 fallback。
+每个基于 base 的 `dsh --profile` 表层都运行在 `dsh-base` 上，因此这些表层共享模型连接、完整工具集、持久会话历史和 workspace 安全默认值。随附的 `sdk-minimal` profile 刻意改用完整的独立配置树。你通常不直接操作本 bundle——随附的 base-backed profile 已经包含它，自定义 base-backed profile 则把它放在第一位。需要其他默认值时，应修改自己的 profile patch 或添加后续 bundle；本包不是供导入的库。
 
-patch 在自身上按平台门控两个 shell 栈：`bash-sandbox`/`tool-bash` 携带 `disabled: !!js process.platform === 'win32'`（bash 没有 Windows runner），它们的孪生行 `pwsh-sandbox`/`tool-pwsh` 以取反的表达式仅在 win32 挂载——同一份 patch 文件，每个宿主恰好挂载一个 shell 栈。权限面与 POSIX 完全一致：`sandbox`/`sandbox-policy` 通过 Windows ACL 受限令牌 runner（`dsh-sandbox-local` 的 win32 链 → `@deepseek-ai/dsh-sandbox-windows-acl`）执行文件效果策略，权限切换器与 approval 服务原样运行，`fs-sandbox` 继续围栏 `ctx.fs` 写入——在其旁再挂载 `dsh-fs-local` 会重复注册 `ctx.fs` 并在加载时失败。偏好不受沙盒约束的本地 pwsh 执行器或完整访问的 Windows 主机通过其 profile 或 home 的 `cordis.patch.yml` 覆盖这些行（bash 恢复配方必须完整：禁用 `pwsh-sandbox`/`tool-pwsh` 并重新启用 `bash-sandbox`/`tool-bash`——两个执行器家族注册同一个 `bash` 服务，配方不完整会在加载时直接报错）。POSIX 主机看到的是被禁用的 pwsh 行。

+## 使用本包
+
+你会自动获得 dsh 核心：随发行版交付的 `web` 与 `headless` profile 已包含它，自定义 profile 则把它列为第一个组合包。之后一切无需任何额外配置即可工作。
+
+### 最小自定义 profile
+
+要在共享核心之上构建 profile，请创建一个 profile，其 `package.json` 把 `@deepseek-ai/dsh-base` 列在首位：
+
+```json
+{
+  "name": "my-profile",
+  "private": true,
+  "dsh": {
+    "profile": {
+      "bundles": ["@deepseek-ai/dsh-base"]
+    }
+  }
+}
+```
+
+运行 `dsh --profile my-profile "your task"`，你就得到一个可用的 agent（智能体），带模型访问、工具、持久化与默认权限策略。随发行版交付的 `web` 与 `headless` profile 会在首次使用时为你创建。要添加更多组合包，运行 `dsh plugin --profile <name> add <package>`；内置组合包从 dsh 安装目录解析。profile 约定见 [app-boot 的 profile 章节](../../boot/app-boot/README.zh.md)。
+
+### 你得到什么
+
+开箱即用，基于本核心构建的每个 profile 都提供：DeepSeek 模型连接（provider 与模型可配置，你还可以在设置中启用额外 provider）、完整工具集——文件编辑、shell 命令、web 搜索、subagent、任务与目标跟踪——可跨重启存活的持久会话，以及默认权限策略：把文件写入限制在工作区内，危险操作前征询许可。遥测默认关闭，除非你主动开启。
+
+### 各平台的 shell 工具
+
+在 macOS 与 Linux 上你获得 bash shell 工具；在 Windows 上则获得对应的 PowerShell 孪生工具，因此每台机器恰好有一套 shell 栈。各平台的安全行为完全一致。偏好不受沙盒约束的 PowerShell 执行器的 Windows 主机可以在其 profile patch 中切换 shell 行——切换必须同时禁用两个 PowerShell 行并重新启用两个 bash 行，否则 profile 无法加载。
+
+### 更改默认值
+
+要改变基于本核心构建的 profile 提供的内容——不同的默认模型、更严格的权限模式、更多或更少的工具——请编辑 profile 的 `cordis.patch.yml` 或添加后面的组合包。每个 patch 条目会替换目标的整个配置，因此请重述每个想保留的设置。保持沙箱化文件系统提供方作为唯一的文件写入路径：在其之上再添加普通文件系统提供方会导致 profile 加载失败。

+
+本组合包是一份静态 patch 文档：一个应用到空 profile 根之上的 `insert` 列表。它不挂载任何服务、不发出任何事件、也不持有任何可变状态；每条插入行所属的包负责该行的行为与不变式。
+
+### 组合机制
+
+patch 会替换目标行的整个 `config`，而不是合并进它。后续组合包层与用户的 profile `cordis.patch.yml` 按 id 覆盖行，每行最后一次写入生效。按模式取值不同的行不属于这里：每个模式组合包重述自己的完整配置，让任何单一行最多只属于一个组合包层加用户层。完整行集合及其设计依据以行内注释写在 [`cordis.patch.yml`](cordis.patch.yml) 里；[生成的组合图](../../../apps/cli/composition.md)负责渲染它。
+
+### 平台门控
+
+patch 在自身上按平台门控两个 shell 栈：`bash-sandbox` 与 `tool-bash` 携带 `disabled: !!js process.platform === 'win32'`，孪生行 `pwsh-sandbox` 与 `tool-pwsh` 以取反的表达式仅在 win32 挂载。权限面与 POSIX 完全一致：沙箱策略通过 Windows ACL 受限令牌 runner（`dsh-sandbox-local` → `@deepseek-ai/dsh-sandbox-windows-acl`）执行相同的文件效果策略，`fs-sandbox` 继续围栏 `ctx.fs` 写入——在其旁再挂载 `dsh-fs-local` 会重复注册 `ctx.fs` 并在加载时失败。

+- **按表层的设置属于该表层的组合包**——web GUI 与 headless 模式取值不同的默认值放在对应表层的组合包里，而不是共享核心。
 - **Windows 的临时目录授权是按会话的私有子目录**——`workspace-write` 把写入限制在工作区与会话自己的 temp 子目录（`<temp>\dsh-<hash>`，受限子进程的 TMP/TEMP 被改写）；`read-only` 不授予任何临时目录写入权限。见 `@deepseek-ai/dsh-sandbox-windows-acl`。

-The dsh one-shot bundle. [`cordis.patch.yml`](cordis.patch.yml) rides directly over [`dsh-base`](../base/README.md): it inherits the base's disabled module-HMR policy and projection cache, supplies the coding persona and tool mode, mounts Code Mode's worker as a core execution capability, and inserts this package's `headless-runner` plugin (config `{task}`, resolved from the injected `headlessStartup` provider). It mounts no Host, HTTP server, Web runtime, or browser plugin. The cache checkpoints each persisted one-shot session for later consumers; its durability barrier flushes each covered log prefix before publishing the cache row and may split otherwise coalesced JSONL runs.
+## Summary
 
-After the Loader settles, the runner reads the shared [`ctx.agentDefaultModel`](../../core/agent-default-model/README.md), creates one fresh persisted Agent through `ctx.agents`, submits the task as an ordinary user message, and waits for quiescence. Each non-empty provider reasoning delta from that Agent is written to stderr as it arrives under a `dsh: reasoning:` heading; consecutive deltas remain one section, and the runner terminates the section before later output when the provider supplied no trailing newline. It then flushes the Session before folding the owned durable event interval, writes the last non-empty assistant text to stdout, and requests exit through the launcher-provided `ctx.appExit` host hook ([`dsh-cmdline`](../../boot/cmdline/README.md)) (final `turn/end` completed → 0, otherwise 1). A terminal `error` reason also writes its code and message to stderr; a successful run with no reasoning keeps stderr empty. The process opens no listening port.
+`dsh-headless` runs one dsh task from the command line and prints the final answer, then exits — no GUI, no server, no browser. Type `dsh --profile headless "run the tests"` and the agent works through the task with the same model, tools, and safety defaults as every other surface. It is ideal for scripts, CI, and one-off jobs: the process opens no ports and leaves nothing running behind. The exit code tells you the outcome — 0 when the task completed, 1 when it aborted or errored. The main boundary: one task per invocation, with no interactive follow-up.
 
-The task text is this app's command line: the ordinary `headless-startup` provider ([`src/startup.ts`](src/startup.ts)) injects `ctx.cmdlineArgs` ([`dsh-cmdline`](../../boot/cmdline/README.md)), reads the positional argument of `dsh --profile headless "task"`, prints the app's `--help`, and provides `headlessStartup`; the runner injects that service and reads its task from lazy config. A missing or whitespace-only task is rejected before the runner activates.

+## Use this package
+
+Run one task, get the final answer, and exit. The task is the command line itself, so the whole invocation is the smallest working example.
+
+### Running a one-shot task
+
+```sh
+dsh --profile headless "run the tests"
+```
+
+The agent works through the task, streams each non-empty provider reasoning delta to stderr under a `dsh: reasoning:` heading, then prints the final answer on stdout and exits. Consecutive reasoning deltas stay in one section, and the runner closes that section before later output when the provider supplied no trailing newline. A successful run without reasoning keeps stderr empty; a failure exits 1 and prints `dsh: <code>: <message>` to stderr. A missing or blank task is rejected before anything runs. The task text is supplied through the single `task` setting:
+
+| Field | Default | Meaning |
+|---|---|---|
+| `task` | required | The task text for the single run |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-headless) is the exhaustive source for every accepted field and its JSDoc.
+
+### When to use it
+
+Use headless for scripted or automated dsh runs — CI steps, batch jobs, quick answers from a terminal. Avoid it when you need a multi-turn interactive session or a GUI; the browser surface ([dsh-web-app](../web-app/README.md)) serves that. The process stays alive only for the run, opens no listening port, and exits on its own, so it fits pipelines that wait on the process.
+
+### Help and task errors
+
+`dsh --profile headless --help` prints the command's help text and exits without running anything. A missing or whitespace-only task is a usage error: nothing runs and the process exits 1.

+<a id="understand-the-implementation"></a>
+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+The runner is a direct driver over the core API carrier: it creates one fresh Agent through the registry and folds the owned durable event interval into one process-level outcome.
+
+### Run flow
+
+The runner awaits the complete application (`ctx.get('loader')?.await()`) so the composed tools and adapters are not half-mounted, reads the shared [`agentDefaultModel`](../../core/agent-default-model/README.md) selection, creates one fresh persisted Agent with that provider and model, and submits the task as an ordinary user message. It streams that Agent's non-empty reasoning deltas to stderr, waits for quiescence, then flushes the Session and folds the owned interval (`firstSeq` onward) into the last non-empty `assistant/message` text and final `turn/end` reason. It writes the final text to stdout and requests exit.
+
+### Patch surface over base
+
+The patch rides over `dsh-base`: it inherits the projection cache, sets the coding persona on the base `system-prompt` row, keeps the same temporary process-wide Code Mode opt-in (`DSH_TOOLS_MODE`) as the Web surface, disables the shared HMR row, inserts Code Mode's worker as a core execution capability, and mounts the startup provider and the runner. The cache checkpoints each persisted one-shot session for later consumers; its durability barrier flushes each covered log prefix before publishing the cache row and may split otherwise coalesced JSONL runs. The startup provider ([`src/startup.ts`](src/startup.ts)) injects `ctx.cmdlineArgs` ([`dsh-cmdline`](../../boot/cmdline/README.md)), reads the positional argument, prints the app's `--help`, and provides `headlessStartup`; the runner injects that service and reads its task from lazy config.
+
+### Exit mapping
+
+A completed final `turn/end` exits 0; any other outcome — aborted, error, or no turn in the owned interval — exits 1. An `error` reason also writes `dsh: <code>: <message>` to stderr. A direct driver failure (for example, Agent creation) writes `dsh: <message>` to stderr and exits 1.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | The `headless-runner` plugin: run flow, output contract, exit mapping |
+| [`src/startup.ts`](src/startup.ts) | The `headless-startup` provider: task positional and `--help` |
+| [`cordis.patch.yml`](cordis.patch.yml) | The one-shot patch over `dsh-base` |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion: no runtime invariant; the observable contract is process-level |
+| [`tests/headless.spec.ts`](tests/headless.spec.ts) | Run flow, aggregation, flush, and exit mapping |
+| [`tests/startup.spec.ts`](tests/startup.spec.ts) | Command-line parsing over a real Loader tree |
+
+### Invariant ownership
+
+The invariant companion registers an empty installer because the runner's observable contract (final text on stdout, exit code by turn-end reason) is process-level and owned by the launcher e2e; the plugin registers nothing and holds no mutable relation to audit inside the tree.

 ## Known Limitations and Deferred Work
 
-- **One submitted task only** — the runner has no interactive follow-up surface; it waits through any work the Agent completes before returning to idle and prints the last non-empty assistant message in that interval.
-- **No pre-token heartbeat** — stderr remains silent until the provider emits a non-empty reasoning delta; a provider that delays its first streamed token exposes no earlier progress signal.
-- **Reasoning enters stderr logs** — redirection and supervisors may retain substantially more and potentially sensitive model output; route stderr to a controlled sink when that content must not be collected.
-- **`ctx.appExit` is launcher-owned** — booting the headless profile outside the `dsh` launcher fails loud at activation until the host provides the exit request.
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits tell you when headless does not fit and what it needs from the `dsh` launcher. They are current package constraints, not a general CLI comparison or a task backlog.
+
+- **One task per run** — after the task is answered the process exits; there is no interactive follow-up, so split multi-step work into separate runs.
+- **Runs through the `dsh` launcher** — starting the headless profile another way fails at startup, because only the launcher can request the process exit.
+- **No pre-token heartbeat** — stderr stays silent until the provider emits a non-empty reasoning delta; a delayed first token exposes no earlier progress signal.
+- **Reasoning enters stderr logs** — redirection and supervisors may retain substantially more and potentially sensitive model output; route stderr to a controlled sink when needed.
+- **Only reasoning and the final answer are printed** — a run without an assistant message prints an empty stdout line and exits 1; intermediate tool output is not printed.

-Loader 结算后，runner 读取共享的 [`ctx.agentDefaultModel`](../../core/agent-default-model/README.zh.md)，通过 `ctx.agents` 创建一个全新的持久化 Agent（智能体），将任务作为普通用户消息提交，并等待完全停稳。该 Agent 每次产生非空的提供方推理分片时，runner 都会在 `dsh: reasoning:` 标题下将其即时写入 stderr；连续分片保留在同一段中，提供方没有输出末尾换行时，runner 会在后续输出前终止该段。随后，它对 Session 执行 flush，再汇总自身持有的持久化事件区间，将最后一条非空 assistant 文本写入 stdout，并经启动器提供的 `ctx.appExit` 宿主钩子（[`dsh-cmdline`](../../boot/cmdline/README.zh.md)）请求退出（最终 `turn/end` 完成 → 0，否则为 1）。最终结束原因为 `error` 时，还会将 code 与 message 写入 stderr；没有推理内容的成功运行会保持 stderr 为空。进程不会打开监听端口。
+`dsh-headless` 从命令行运行一个 dsh 任务并打印最终答案，然后退出——没有 GUI、没有服务器、没有浏览器。输入 `dsh --profile headless "run the tests"`，agent（智能体）会以与其他表层相同的模型、工具与安全默认值完成该任务。它非常适合脚本、CI 与一次性任务：进程不打开任何端口，也不会留下任何后台运行的东西。退出码告诉你结果——任务完成时为 0，中止或出错时为 1。主要边界：每次调用只运行一个任务，没有交互式后续。
 
-任务文本就是这个应用的命令行：普通 `headless-startup` 提供方（[`src/startup.ts`](src/startup.ts)）注入 `ctx.cmdlineArgs`（[`dsh-cmdline`](../../boot/cmdline/README.zh.md)），读取 `dsh --profile headless "task"` 的位置参数、打印应用自己的 `--help`，并提供 `headlessStartup`；runner 注入该服务，再从惰性配置中读取任务。缺失或只有空白的任务会在 runner 激活前被拒绝。

+## 使用本包
+
+运行一个任务，获得最终答案，然后退出。任务就是命令行本身，因此整条命令就是最小的可运行示例。
+
+### 运行一次性任务
+
+```sh
+dsh --profile headless "run the tests"
+```
+
+agent（智能体）会完成该任务，把提供方的每个非空推理增量流式写入 stderr 的 `dsh: reasoning:` 段，然后把最终答案写入 stdout 并退出。连续推理增量保持在同一段中；提供方未给尾换行时，runner 会在后续输出前结束该段。没有推理内容的成功运行保持 stderr 为空；失败时退出码为 1，并以 `dsh: <code>: <message>` 向 stderr 写入错误。缺失或空白任务会在任何内容运行前被拒绝。任务文本通过唯一的 `task` 设置提供：
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `task` | 必填 | 单次运行的任务文本 |
+
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-headless)是每个受支持字段及其 JSDoc 的穷尽式真源。
+
+### 何时使用
+
+在脚本化或自动化的 dsh 运行中使用 headless——CI 步骤、批处理任务、从终端快速获取答案。当需要多轮交互会话或 GUI 时请避免它；浏览器表层（[dsh-web-app](../web-app/README.zh.md)）负责这类场景。进程只为本次运行而存活，不打开监听端口，并且自行退出，因此适合等待进程结束的流水线。
+
+### 帮助与任务错误
+
+`dsh --profile headless --help` 打印该命令的帮助文本并直接退出，不运行任何内容。缺失或只有空白的任务属于用法错误：什么都不运行，进程退出 1。

+runner 是核心 API 载体之上的直接驱动器：它通过注册表创建一个全新的 Agent（智能体），并把所属的持久化事件区间折叠成一个进程级结果。
+
+### 运行流程
+
+runner 等待整个应用结算（`ctx.get('loader')?.await()`），确保已组合的工具与适配器不会半挂载，读取共享的 [`agentDefaultModel`](../../core/agent-default-model/README.zh.md) 选择，用该 provider 与模型创建一个全新的持久化 Agent（智能体），并把任务作为普通用户消息提交。它把该 Agent 的非空推理增量流式写入 stderr、等待完全停稳，然后 flush Session，并把所属区间（从 `firstSeq` 起）折叠为最后一条非空 `assistant/message` 文本与最终 `turn/end` 原因。最后，它把最终文本写入 stdout 并请求退出。
+
+### 叠加在 base 之上的 patch 表层
+
+patch 叠加在 `dsh-base` 之上：继承投影缓存，在基础 `system-prompt` 行上设置编码 persona，保留与 Web 表层相同的临时进程级 Code Mode 开关（`DSH_TOOLS_MODE`），禁用共享的 HMR 行，把 Code Mode 的 worker 作为核心执行能力插入，并挂载启动提供方与 runner。缓存为每个已持久化的一次性会话写入检查点，供后续消费方使用；其持久性屏障会在发布缓存行前 flush 所覆盖的日志前缀，因此可能拆分原本会合并的 JSONL 行。启动提供方（[`src/startup.ts`](src/startup.ts)）注入 `ctx.cmdlineArgs`（[`dsh-cmdline`](../../boot/cmdline/README.zh.md)），读取位置参数、打印应用自己的 `--help`，并提供 `headlessStartup`；runner 注入该服务，再从惰性配置中读取任务。
+
+### 退出映射
+
+最终 `turn/end` 完成时退出码为 0；任何其他结果——aborted、error，或所属区间内没有轮次——退出码为 1。结束原因为 `error` 时还会向 stderr 写入 `dsh: <code>: <message>`。直接驱动器失败（例如 Agent 创建失败）向 stderr 写入 `dsh: <message>` 并退出 1。
+
+### 源码地图

-- **只提交一个任务**：runner 没有用于交互式后续输入的 surface；它会等待 Agent 在返回 idle 前完成的所有工作，并打印该区间内最后一条非空 assistant 消息。
-- **首个 token 前没有心跳**：在提供方发出非空推理分片前，stderr 保持静默；如果提供方延迟首个流式 token，系统不会提供更早的进度信号。
-- **推理会进入 stderr 日志**：重定向与监督进程可能保留明显更多且可能敏感的模型输出；不得收集该内容时，应将 stderr 送往受控目标。
-- **`ctx.appExit` 由启动器持有**：在 `dsh` 启动器之外启动 headless profile 会在激活时明确报错，直到宿主提供该退出请求。

+
+
+这些限制告诉你 headless 何时不适用、它需要 `dsh` 启动器提供什么。它们是当前包约束，不是通用的 CLI 对比或任务积压。
+
+- **每次运行一个任务**——任务得到回答后进程即退出；没有交互式后续，因此多步工作请拆成多次运行。
+- **通过 `dsh` 启动器运行**——以其他方式启动 headless profile 会在启动时失败，因为只有启动器能请求进程退出。
+- **首个 token 前没有心跳**——提供方发出第一个非空推理增量前，stderr 保持静默；延迟首个 token 的提供方不会更早给出进度信号。

 The startup provider binds stdin EOF to the launcher's bounded successful shutdown. SDK protocol `shutdown`, SIGINT, and SIGTERM retain their owning server or launcher paths; disposal drains the root profile tree and persistence. Stdout is reserved for newline-delimited JSON-RPC frames. The bundle disables model-generated session titles because the SDK exposes no title surface; deterministic fallback titles remain durable without an auxiliary model request. The inherited projection cache checkpoints SDK-created sessions for later consumers; its durability barrier flushes each covered log prefix before publishing the cache row and may split otherwise coalesced JSONL runs. A deployment selects a different complete composition through profile bundles and patch files, not another app bin.

-Standalone minimal SDK application bundle for `dsh --profile sdk-minimal`. Its single insert is the complete Cordis tree: SDK stdio startup and JSON-RPC serving, one environment-configured DeepSeek adapter, the executor-less agent spine, local subprocess and unrestricted filesystem providers, a platform-selected persistent shell PTY, the string-replace editor, and uncompressed JSONL session persistence under `$DSH_HOME/sessions`. It deliberately does not include [`dsh-base`](../base/README.md), Web, settings, managed credentials, telemetry, compaction, workspace instructions, skills, jobs tools, subagents, or any other model-facing tool.
+## Summary
 
-The profile remains part of the ordinary launcher and layering model. The bundle supplies the complete default tree; the profile patch, home patch, and ordered `--patch` files can replace rows or insert external bundles above it. `dsh plugin --profile sdk-minimal` manages persistent dependencies. The shipped template uses startup-only patches so one stdio connection never observes replacement of its server or agent dependencies.
+Use `dsh --profile sdk-minimal` when an SDK client needs a small, explicit coding-agent runtime. The profile advertises a platform-selected persistent shell and `str_replace_editor`, persists sessions as uncompressed JSONL, and selects the model from the SDK initialization request. It supplies a complete Cordis tree and deliberately excludes `dsh-base`, Web, settings, managed credentials, telemetry, compaction, workspace instructions, skills, jobs, and subagents. Its danger-full-access policy lets the shell and editor modify any path available to the process, so use it only with an isolated workspace.
 
-`DEEPSEEK_API_KEY` supplies the adapter credential. The SDK initialization request is the sole model selection; the adapter accepts that model id even when it is absent from its advisory catalog. `DSH_CONTEXT_WINDOW` sets the fallback capacity for such models, and `DSH_SYSTEM_PROMPT` replaces the default persona. The process working directory is the sandbox-policy workspace and local-filesystem root. The bundle sets `danger-full-access`; its persistent shell and editor can modify any path available to the process.
+## Table of Contents
 
-Exactly one persistent shell stack mounts by platform: Bash on Linux/macOS or PowerShell on Windows. Both use a 300-second timeout and one owner-scoped terminal; the other platform rows remain disabled.

 # `@deepseek-ai/dsh-sdk-minimal`
 
 [English](README.md) | 中文
 
-供 `dsh --profile sdk-minimal` 使用的独立极简 SDK 应用组合包。它的单个 insert 构成完整 Cordis 树：SDK stdio 启动与 JSON-RPC 对外服务、一个由环境配置的 DeepSeek 适配器、无执行器的 agent 主干、本地子进程与不受限文件系统提供方、按平台选择的持久 shell PTY、字符串替换编辑器，以及位于 `$DSH_HOME/sessions` 的未压缩 JSONL 会话持久化。它刻意不包含 [`dsh-base`](../base/README.zh.md)、Web、settings、托管凭据、遥测、压缩（compaction）、workspace 指令、skills、jobs 工具、subagent 或任何其他面向模型的工具。
+## 概述
 
-该 profile 仍遵循普通 launcher 与分层模型。组合包提供完整默认树；profile patch、home patch 与有序 `--patch` 文件可以在其上替换配置项或插入外部组合包。`dsh plugin --profile sdk-minimal` 管理持久依赖。随附模板仅在启动时应用 patch，因此一个 stdio 连接不会观察到服务器或 agent 依赖在运行中被替换。
+当 SDK 客户端需要小型、显式的 coding agent 运行时时，请使用 `dsh --profile sdk-minimal`。该 profile 只公布按平台选择的持久 shell 与 `str_replace_editor`，把会话持久化为未压缩 JSONL，并从 SDK 初始化请求选择模型。它提供完整 Cordis 配置树，并刻意排除 `dsh-base`、Web、settings、托管凭据、遥测、compaction、workspace 指令、skills、jobs 与 subagent。其 danger-full-access 策略允许 shell 与编辑器修改进程可访问的任何路径，因此只能配合隔离 workspace 使用。
 
-`DEEPSEEK_API_KEY` 提供适配器凭据。SDK 初始化请求是唯一模型选择；即使该模型 id 不在适配器的建议目录中，适配器也会接受它。`DSH_CONTEXT_WINDOW` 为这类模型设置后备容量，`DSH_SYSTEM_PROMPT` 替换默认 persona。进程工作目录同时作为沙箱策略 workspace 与本地文件系统根目录。该组合包设置 `danger-full-access`；其持久 shell 与编辑器可以修改进程可访问的任何路径。
+## 目录
 
-运行时会按平台恰好挂载一套持久 shell：Linux／macOS 使用 Bash，Windows 使用 PowerShell。两者都使用 300 秒超时与一个 agent 自有终端；另一平台的配置项保持禁用。

 English | [中文](README.zh.md)
 
-The dsh browser-surface bundle. [`cordis.patch.yml`](cordis.patch.yml) rides over [`dsh-base`](../base/README.md): it sets the coding persona, inserts the Web host rows (webserver, API gateway, workspace) and the browser plugin roster, the always-on client-plugin reload chain ([`dsh-client-hmr`](../../client/hmr/README.md), idle until a rebuild watcher rewrites client bundles), and mounts this package's `web-runtime` glue plugin (config `{openBrowser, printUrl, surfaceContext, trustedHosts}`). The storage stack and the projection cache ride in the shared base bundle; the web overlay's workspace and message-feedback rows consume the base `storageDomain` service. That plugin resolves the built frontend dist through `@deepseek-ai/dsh-web-frontend`'s exports, samples bind-dependent LAN trust once, provides it as `webRuntime` to the browser-trust fence and client roster, mounts the [`frontend-static`](../../host/frontend-static/README.md) fallback owner, and registers the harness-source and web-surface prompt sections plus the bash-visible `DSH_WEB_URL` runtime variable when `surfaceContext` is true. After its Loader tree settles and Connection authentication is available, it prints the `dsh web:` root URL with the fresh process token when `printUrl` is true and opens that authenticated URL in the default browser when `openBrowser` is true and the inherited `SSH_CONNECTION` and `SSH_TTY` are blank or absent. The model prompt and `DSH_WEB_URL` retain the clean canonical URL without credentials. An SSH launch keeps the tokenized URL line but suppresses browser handoff because the SSH client or editor owns the local forwarded address. Immediately before a handoff, the runtime prints `dsh web: opening the default browser; pass --no-open to disable`. A short-lived Node helper runs the maintained platform opener with the canonical scrubbed child environment. On Windows it stays alive until the short-lived PowerShell launcher exits, because `open` reports spawn before that launcher has handed the URL to the shell; elsewhere the helper stops after the opener accepts spawn. A helper failure writes a credential-free diagnostic with its reason and points to the startup URL without stopping the server, and no path waits for the browser to exit. This bundle also owns the app command line: the ordinary `web-startup` provider ([`src/startup.ts`](src/startup.ts)) injects `ctx.cmdlineArgs` ([`dsh-cmdline`](../../boot/cmdline/README.md)), parses `--host`, `--port`, repeatable `--trusted-host`, `--no-open`, and the app's `--help`, then provides `webStartup`; browser opening defaults on for local launches, and `--no-open` turns it off for this invocation. It rejects `--host 0.0.0.0` before publishing that service because the CLI intentionally does not support all-interfaces binding. Flag-configured rows inject the service and read it directly from lazy config, so nothing binds a port before argument resolution and `dsh --profile web --help` starts no server. [`dsh-headless`](../headless/README.md) is a sibling surface over the same base and does not mount this bundle.
+## Summary
 
-The base module-HMR row remains disabled. The Web profile's `patchReload: live` lifecycle uses the launcher's config-only watcher; the browser-facing `dsh-client-hmr` reload chain is separate from server module HMR.
+Run `dsh --profile web` and the interface opens in your default browser, ready for interactive chat with the agent. You get the conversation view, model and settings management, and session history, backed by the same model access, tools, and safety defaults as every other surface. The command prints a tokenized startup URL; the browser exchanges that token for a signed session cookie and redirects to the clean root URL. You can change the port, suppress the browser handoff, and allow extra hosts from the command line; binding all network interfaces is intentionally not supported. Choose it for interactive work in the browser; `dsh-headless` is the one-shot command-line sibling.
 
-## Model retry defaults
+## Table of Contents
 
-Web uses the shared bounded normal default of five eligible retries after the initial request. The `deepseek-official` route and settings-added pi-ai routes use that default when they omit `retryPolicy`; explicit provider policies still win. Web adds no retry-specific composition override, so the same omission behavior applies to non-Web profiles.

+## Use this package
+
+Start the GUI, open your browser, and start talking to the agent. The flags fine-tune the invocation.
+
+### Starting the Web GUI
+
+```sh
+dsh --profile web
+dsh --profile web --no-open --port 8080
+```
+
+After startup you see a `dsh web:` line whose root URL carries a fresh process token. Unless `--no-open` or an SSH session suppresses it, the default browser opens that URL, receives a signed cookie, and redirects to the clean root page. You know it worked when the page loads and you can chat with the agent. Two failures to expect: if the frontend is not built, startup stops with a build hint (`pnpm run build` in a checkout); if the browser cannot be opened, a credential-free diagnostic prints to stderr while the server keeps running — open the printed startup URL yourself.
+
+### Configuration
+
+Most users never set these; the command-line flags feed the four settings below — `--host`, `--port`, and `--trusted-host` come from the invocation, and `--no-open` turns the browser handoff off for that invocation:
+
+| Field | Default | Meaning |
+|---|---|---|
+| `openBrowser` | `true` | Open the default browser after startup; SSH launches suppress it |
+| `printUrl` | `true` | Print the `dsh web:` URL line at startup |
+| `surfaceContext` | `true` | Give the agent GUI-orientation context and expose `DSH_WEB_URL` to its shell commands |
+| `trustedHosts` | `[]` | Extra hosts allowed to reach the GUI from the network |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-web-app) is the exhaustive source for every accepted field and its JSDoc.
+
+### LAN access and trusted hosts
+
+By default the GUI accepts connections from this machine only. A deployment that binds all network interfaces also allows browsers from the LAN, and the printed URL then includes a LAN address; `--trusted-host` adds extra hosts in either case. Host and Origin checks control reachability, while the token exchange authenticates every Host API method and WebSocket stream. The LAN addresses are sampled once at startup, so a network change later is not picked up — restart the GUI to re-advertise.
+
+### Running over SSH
+
+When you launch `dsh --profile web` over SSH, the URL line still prints but the browser is not opened for you: the SSH client or editor owns the local forwarding address. Open the forwarded URL on your machine yourself; the printed URL names the remote host's loopback endpoint.
+
+### Per-session agent setup
+
+Each browser session composes its own agent from the shipped presets (the `standard` preset by default), instead of sharing one process-wide tool set. You can change the default preset or add your own presets under `$DSH_HOME/.agent-presets`.
+
+-----
+
+<a id="understand-the-implementation"></a>
+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+The bundle is one patch plus one runtime glue plugin. The storage stack and projection cache come from `dsh-base`; the web overlay's workspace and message-feedback rows consume that shared `storageDomain` service. The patch restates the surface-specific values the base deliberately omits, inserts the web-only host rows and browser roster, then moves the agent plane behind presets. The glue plugin owns dist serving, trust sampling, prompt sections, the bash variable, and the readiness announcements.
+
+### Patch semantics
+
+A patch replaces the targeted row's whole `config`, so each web row restates every key it owns: the persona, the `DSH_TOOLS_MODE` Code Mode opt-in, and the `session-query-sqlite` values on the base rows, then `insert` adds the web host rows, transport, and browser roster. The per-agent tool rows the base mounts process-wide are disabled here and the preset roster takes over; the reasoning for each host-plane versus preset-plane decision is inline in the patch.
+
+### Readiness
+
+The URL line and browser handoff are readiness signals: supervisors RPC as soon as they observe the line, and a browser requests the page as soon as it opens, so both run only after the Loader tree settles and Connection authentication is available — or immediately in a hand-built tree without a Loader. A tree disposed mid-boot announces nothing.
+
+### LAN trust sampling
+
+`resolveLanTrust` samples the network once at boot: a loopback bind (`127.0.0.1`) derives no LAN addresses, while an all-interfaces bind adds every non-internal IPv4 literal. The derived literals plus the explicit `--trusted-host` authorities form the `/api` browser-trust fence, and the printed LAN URL always matches that fence.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | The `web-app` glue plugin: dist resolution, LAN trust sampling, prompt sections, bash variable, URL line, browser handoff |
+| [`src/startup.ts`](src/startup.ts) | The `web-startup` provider: `--host`, `--port`, `--trusted-host`, `--no-open`, `--help` |
+| [`cordis.patch.yml`](cordis.patch.yml) | The web patch: restated base values, web host rows, browser roster, agent plane behind presets |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion: no runtime invariant; every contribution is registry-disposed |
+| [`tests/web-app.spec.ts`](tests/web-app.spec.ts) | Dist resolution, fallback seat, prompt sections, readiness |
+| [`tests/startup.spec.ts`](tests/startup.spec.ts) | Command-line parsing over a real Loader tree |
+| [`tests/trusted-hosts.spec.ts`](tests/trusted-hosts.spec.ts) | LAN-trust sampling |
+| [`tests/browser-open.spec.ts`](tests/browser-open.spec.ts) | Default-browser handoff after the page is reachable |
+
+### Invariant ownership
+
+The invariant companion registers an empty installer because every contribution — the frontend-static child plugin, the prompt sections, and the bash variable registration — is registry-disposed with the fiber, and each owning registry's package carries that relation's invariant.

-dsh 浏览器表层组合包。[`cordis.patch.yml`](cordis.patch.yml) 叠加在 [`dsh-base`](../base/README.zh.md) 之上：设置 coding persona，插入 Web 宿主行（webserver、API 网关、workspace）、浏览器插件名录与始终挂载的客户端插件重载链（[`dsh-client-hmr`](../../client/hmr/README.zh.md)，在重建 watcher 改写客户端 bundle 之前保持空闲），并挂载本包的 `web-runtime` 粘合插件（配置为 `{openBrowser, printUrl, surfaceContext, trustedHosts}`）。存储栈与投影缓存随共享 base 组合包提供；Web 覆盖层的 workspace 与 message-feedback 行消费 base 的 `storageDomain` 服务。该插件通过 `@deepseek-ai/dsh-web-frontend` 的 exports 解析已构建的前端 dist，只采样一次依赖 bind 的 LAN 信任信息并将其作为 `webRuntime` 提供给浏览器信任栅栏和客户端名录，挂载 [`frontend-static`](../../host/frontend-static/README.zh.md) 回退席位所有者，并在 `surfaceContext` 为 true 时注册 Harness 源码与 Web 表层提示词段落，以及 bash 可见的 `DSH_WEB_URL` 运行时变量。Loader 配置树结算且 Connection 认证可用后，它在 `printUrl` 为 true 时打印带新进程令牌的 `dsh web:` 根 URL；`openBrowser` 为 true 且继承的 `SSH_CONNECTION` 与 `SSH_TTY` 均为空或不存在时，才会用默认浏览器打开该认证 URL。模型提示词与 `DSH_WEB_URL` 仍携带不含凭据的干净规范 URL。SSH 启动仍保留带令牌的 URL 行，但会跳过浏览器交接，因为本地转发地址由 SSH 客户端或编辑器持有。交接前，运行时会打印英文提示 `dsh web: opening the default browser; pass --no-open to disable`。短生命周期 Node helper 使用规范的脱敏子进程环境运行受维护的平台 opener。在 Windows 上，helper 会保持存活，直至短生命周期的 PowerShell launcher 退出，因为 `open` 会在 launcher 把 URL 交给 shell 之前、仅在 spawn 时返回；其他平台则在 opener 接受 spawn 后结束。helper 失败时会向 stderr 写入不含凭据的原因并指向启动 URL，不会停止服务器，且任何路径都不会等待浏览器退出。本组合包还持有应用命令行：普通 `web-startup` 提供方（[`src/startup.ts`](src/startup.ts)）注入 `ctx.cmdlineArgs`（[`dsh-cmdline`](../../boot/cmdline/README.zh.md)），解析 `--host`、`--port`、可重复的 `--trusted-host`、`--no-open` 以及应用自己的 `--help`，再提供 `webStartup`；本机启动默认会打开浏览器，`--no-open` 则只对本次调用关闭该行为。它会在发布该服务前拒绝 `--host 0.0.0.0`，因为 CLI 不支持绑定所有网络接口。由 flag 配置的行会注入该服务，并在惰性配置中直接读取它，因此参数解析完成前不会有任何东西绑定端口，`dsh --profile web --help` 也不会启动服务器。[`dsh-headless`](../headless/README.zh.md) 是同一 base 之上的同级表层，不挂载本组合包。
+## 概述
 
-base 的模块 HMR 配置项保持禁用。Web profile 的 `patchReload: live` 生命周期使用启动器的仅配置 watcher；面向浏览器的 `dsh-client-hmr` 重载链与服务器模块 HMR 相互独立。
+运行 `dsh --profile web`，界面会在你的默认浏览器中打开，即可与 agent（智能体）交互式聊天。你会获得会话视图、模型与设置管理以及会话历史，背后与其他表层相同的模型访问、工具与安全默认值。该命令会打印带 token 的启动 URL；浏览器用该 token 换取签名会话 cookie，再重定向到干净的根 URL。你可以从命令行更改端口、关闭浏览器交接并允许额外主机；有意不支持绑定所有网络接口。需要浏览器中的交互式工作时选择它；`dsh-headless` 是一次性的命令行兄弟表层。
 
-## 模型重试默认值
+## 目录
 
-Web 使用共享的有界 normal 默认值，在首次请求后最多再重试五次符合条件的失败。`deepseek-official` 与由 settings 新增的 pi-ai 路由在省略 `retryPolicy` 时使用该默认值；显式提供方策略仍然优先。Web 不再增加重试专用的组合覆盖，因此非 Web profile 的省略行为与之相同。

+## 使用本包
+
+启动 GUI、打开浏览器，然后开始与 agent（智能体）对话。flag 用于微调本次调用。
+
+### 启动 Web GUI
+
+```sh
+dsh --profile web
+dsh --profile web --no-open --port 8080
+```
+
+启动后你会看到 `dsh web:` 行，其根 URL 携带新的进程 token。除非 `--no-open` 或 SSH 会话抑制，否则默认浏览器会打开该 URL、取得签名 cookie，再重定向到干净的根页面。页面加载且你可以与 agent（智能体）对话，就说明成功了。两种可预期的失败：前端未构建时，启动会以构建提示停止（checkout 中运行 `pnpm run build`）；浏览器无法打开时，stderr 会打印不含凭据的诊断，但服务器会继续运行——请自行打开已打印的启动 URL。
+
+### 配置
+
+大多数用户不需要设置这些；命令行 flag 会提供给下面四个设置——`--host`、`--port` 与 `--trusted-host` 来自本次调用，`--no-open` 仅对本次调用关闭浏览器交接：
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `openBrowser` | `true` | 启动后用默认浏览器打开；SSH 启动会抑制它 |
+| `printUrl` | `true` | 启动时打印 `dsh web:` URL 行 |
+| `surfaceContext` | `true` | 给 agent（智能体）提供 GUI 定位上下文，并把 `DSH_WEB_URL` 暴露给其 shell 命令 |
+| `trustedHosts` | `[]` | 允许从网络访问 GUI 的额外主机 |

+默认情况下 GUI 只接受本机的连接。绑定所有网络接口的部署也会允许 LAN 内的浏览器访问，此时打印的 URL 会附带一个 LAN 地址；`--trusted-host` 在两种情况下都能添加额外主机。Host 与 Origin 检查控制可达性，token 交换则认证每个 Host API 方法与 WebSocket stream。LAN 地址只在启动时采样一次，因此之后的网络变化不会被感知——重启 GUI 以重新公告。
+
+### 通过 SSH 运行
+
+通过 SSH 启动 `dsh --profile web` 时，URL 行仍会打印，但不会为你打开浏览器：本地转发地址由 SSH 客户端或编辑器持有。请在自己的机器上打开转发后的 URL；打印出的 URL 指向远端宿主机 loopback 端点。
+
+### 按会话的 agent 设置
+
+每个浏览器会话都从随发行版交付的 preset（默认 `standard`）组合自己的 agent（智能体），而不是共享一套进程级工具集。你可以更改默认 preset，或在 `$DSH_HOME/.agent-presets` 下添加自己的 preset。

+<details>
+<summary>实现细节——点击展开</summary>
+
+本组合包是一份 patch 加一个运行时粘合插件。patch 重述 base 刻意省略的表层专属值，插入仅 Web 使用的宿主行与浏览器名录，然后把 agent 层移到 preset 之后；粘合插件负责 dist 服务、信任采样、提示词段落、bash 变量与就绪宣告。
+
+### patch 语义
+
+patch 会替换目标行的整个 `config`，因此每个 Web 行都重述自己拥有的每个键：基础行上的 persona、`DSH_TOOLS_MODE` Code Mode 开关与 `session-query-sqlite` 值，随后 `insert` 添加 Web 宿主行、传输层与浏览器名录。base 以进程级挂载的按 agent 工具行在这里被禁用，由 preset 名录接管；每项宿主层与 preset 层归属决策的理由以行内注释写在 patch 里。
+
+### 就绪宣告
+
+URL 行与浏览器交接都是就绪信号：监督方一观察到该行就发起 RPC，浏览器一打开就请求页面，因此两者只在 Loader 配置树结算且 Connection 认证可用后运行——在没有 Loader 的手工构建树中则立即运行。启动中途被释放的树不会宣告任何内容。
+
+### LAN 信任采样
+
+`resolveLanTrust` 在启动时只采样一次网络：loopback 绑定（`127.0.0.1`）不派生任何 LAN 地址，绑定所有网卡则会加入每个非 internal IPv4 字面量。派生字面量加上显式的 `--trusted-host` 权威标识组成 `/api` 浏览器信任栅栏，打印的 LAN URL 始终与该栅栏一致。

+The `client/` group runs the browser half of the dsh web GUI: it boots the web shell, loads browser-side plugin modules, keeps browser-to-host RPC and event delivery alive, and provides the shared client services and UI feature plugins that render the application. UI features compose through the slot system — each plugin fills declared extension slots with typed props and stores, and the shell renders the assembled tree. All packages here are product packages named `@deepseek-ai/dsh-client-<name>`; the host half that serves the page lives in [`host/`](../host/README.md). Authoring rules live in [AGENTS.md](AGENTS.md), and the module graph, slot model, and object layer are documented in the related notes below.
 
-Each child reference owns its contract and detailed behavior. The [slot system standard](../../.agents/notes/implemented/architecture/2026-07-22-slot-type-chain-implementation.md) and [web client architecture note](../../.agents/notes/implemented/architecture/2026-07-19-gui-web-client-architecture.md) own the cross-package composition and loading decisions.

+## Summary
+
 Protocol and connection-generation layer. The Client plugin mounts `ctx.connection`, containing the shared API client, current-page loopback state, generation-scoped observable `hostDescription`, a generic RPC carrier, and the registration point for one generation source and the connection loop. A generation publishes `hostDescription` and calls `onConnected` only after its source is ready and `host.describe` succeeds; source completion, failure, withdrawal, or an explicit stop clears that value before `ConnectionController` reconnects with backoff.

+## Use this package
+
 The browser uses HTTP POST for API Proxy and generic Remote unary calls. API Gateway owns the `/api/remote.mux` WebSocket and its logical streams; in-process compositions provide equivalent Remote streams through `connection.rpc.open` without opening a WebSocket. The Host half owns the sole `/api` route, Fetch bridge, browser authentication, and Host/Origin checks. Typert Gateway claims its Remote endpoints first, and unclaimed requests fall through to API Proxy. Loopback hostname classification remains package-internal to the browser-facing Client state.
 
+-----
+
+<a id="browser-authentication-and-request-trust"></a>
 ## Browser authentication and request trust
 
 Every Host RPC method and WebSocket stream requires one browser session; there is no method-specific loopback tier. Each process mints a random launch token. `dsh-web-app` prints and opens the ordinary root URL with `?token=...`; `frontend-static` delegates root and index requests to `ctx.connection.authorizeIndex`, which accepts that token only on `GET /`, writes an authority-bound signed cookie, and redirects to clean `/`. A missing, expired, malformed, or wrong-authority cookie returns 401 before RPC dispatch. Static assets remain public. The HTTP carrier accepts no query token outside the root exchange and no Authorization-header token.
@@ -14,12 +38,14 @@ The cookie signing secret is the owner-scoped `client-connection/browser-session
 
 Before authentication, every request still passes `src/api-request-trust.ts`. Its `Host` must be loopback or match a `trustedHosts` entry: exact on `host:port`, any port on port-less entries, both sides WHATWG-normalized. An attached `Origin` must equal that Host and `sec-fetch-site: cross-site` is refused. Malformed configured authorities fail plugin load. These checks defend DNS rebinding and cross-site browser requests; they never establish identity. A failed Host/Origin check returns 403, while a trusted but unauthenticated request returns 401. `dsh web --host 0.0.0.0` remains unsupported.

+<a id="connection-generation"></a>
 ## Connection generation
 
 API Gateway Client registers the internal `$events` logical stream as the sole generation source, independently of whether any `$on` listener exists. The Host attaches all incremental listeners in the API Remotes source factory, then sends one `{ type: 'ready' }` item before events. `ConnectionController` waits for that item and `host.describe` in parallel; `onConnected` cannot start baseline reads until both succeed, so baseline acquisition cannot race ahead of incremental observation.
 
 An ended `$events` stream, a Remote stream error, a non-ready opening item, or a malformed event item invalidates the current generation. The controller immediately withdraws `hostDescription`, publishes `reconnecting`, and rebuilds the `$events` plus `host.describe` handshake after backoff. Gateway mux reconnects the physical WebSocket; Connection generation reopens the logical stream and establishes the next baseline starting point.

-Hot reload for script-loaded client plugins. The web bundle mounts the row unconditionally; without a rebuild watcher (`pnpm run dev:web`) rewriting client bundles, the poll observes no changes and the chain stays idle.
+## Summary
 
-The browser half subscribes to the system SSE channel (`GET /plugins/events`) and reloads one plugin per `rebuilt` frame through a serialized queue. The frame revision makes `invalidate` select that plugin's immutable one-resource combo URL instead of its initial multi-resource URL; `prefetch` loads and registers the new factory while the old fiber still serves. The remaining sequence is `registry.delete` (before the fiber: a bare fiber dispose trips the vendored Loader's self-dispose branch, which would mark the entry disabled), drain the old fiber, delete `entry.fiber`, remove owned `<style data-plugin>` tags, `entry.refresh()` re-imports and remounts, then `fiber.await()` rethrows startup failures loud. Dependents reload through cordis itself: a fiber's activation epoch strings its service providers' uids, so replacing a provider's fiber cascades every dependent with zero client-side graph analysis. The node half detects rebuilds with one interval that stat-polls each graph bundle and optional source map from the module host's pre-read baseline. An unchanged startup row begins watching without a content read or hash; a changed row, or a dirty row after its artifact reappears, enters `rebuilt()`, and only real revision changes are broadcast. Any tsdown watch process producing the artifacts therefore triggers HMR with no builder→host channel.
+`dsh-client-hmr` reloads a browser client plugin in place when its bundle is rebuilt, so a developer editing plugin source sees the change without a full page reload. The reload chain stays idle without a rebuild watcher: only a `pnpm run dev:web`-style process rewriting client bundles produces the rebuilds it reacts to. Each reload swaps one plugin with fresh component state while the data layer (connection, runtime, and Session objects) stays untouched. Everything here is development machinery in the browser; the model never sees it.

+## Use this package
+
+Enable the rebuild watcher for the plugin you are editing, then save: the browser picks up the rebuilt bundle from the dev server and swaps the plugin without reloading the page. Use it during client development; nothing observable happens in a production build, where no watcher rewrites bundles.
+
+### Starting the reload chain
+
+Run `pnpm run dev:web` (or any tsdown watch process that writes the plugin's `lib/client.js`) against the same host; rebuilt plugins are then swapped into the running browser automatically, one at a time.
+
+### What a reload does
+
+Each reload re-executes the plugin bundle and remounts the plugin with fresh state. Plugins that depend on the reloaded one reload with it automatically. A reload that fails is reported visibly and retried from scratch on the next rebuild.
+
+### Configuration
+
+| Field | Default | Meaning |
+|---|---|---|
+| `pollIntervalMs` | `500` | Bundle stat-poll interval in milliseconds |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-client-hmr) is the exhaustive source for every accepted field and its JSDoc.
+
+### Observing success
+
+A successful swap shows the edited UI immediately with no page reload, and the plugin keeps working after the swap. Remember the trade-off: React state inside the reloaded plugin is lost, while session, workspace, and connection state survives.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the reload chain is built; observable behavior is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The chain is two halves with one contract: the node half owns bundle detection and notification, the browser half owns the swap. The node half runs one interval that stat-polls each graph bundle and optional source map from the module host's pre-read baseline. An unchanged startup row starts watching without a content read or hash; a changed row, or a dirty row whose artifact reappears, enters `rebuilt()`, and only real revision changes are broadcast. It also serves `/plugins/events`, an SSE channel broadcasting `graph` and `rebuilt` frames.
+
+### The browser swap
+
+On a `rebuilt` frame the revision makes `invalidate` select that plugin's immutable one-resource combo URL instead of its initial multi-resource URL. `prefetch` loads and registers the new factory while the old fiber still serves. The remaining order is registry-first teardown (`registry.delete` before the fiber's disposer emits `internal/plugin`, or the vendored Loader flags the entry disabled), drain the old fiber's unload, delete `entry.fiber`, remove owned `<style data-plugin>` tags, then `entry.refresh()` re-imports and remounts, and `fiber.await()` rethrows startup failures loud. The swap is safe because execution is pure registration under the lazy-CJS model: every module side effect lives in the factory closure and runs at materialization.
+
+### Cascade and self-reload
+
+A fiber's activation epoch strings its service providers' uids, so replacing a provider's fiber re-cascades every dependent through cordis itself with zero HMR-side bookkeeping. This plugin is itself a graph entry, so a rebuilt frame may name it; the in-flight reload keeps running in the old bundle's closure and the new bundle's apply opens a fresh channel.
+
+### Failure policy
+
+No rollback: an import failure leaves the entry fiberless (the next rebuilt frame retries from scratch), and an apply failure leaves a FAILED fiber visible in the shell's status projection. Both log loudly.

-为通过脚本加载的客户端插件提供热重载。web 组合包无条件挂载该行；没有重建 watcher（`pnpm run dev:web`）改写客户端 bundle 时，轮询观察不到变化，链路保持空闲。
+## 概述
 
-浏览器侧订阅系统 SSE（Server-Sent Events）通道（`GET /plugins/events`），每个 `rebuilt` 帧重载一个插件，并通过队列串行执行。帧内 revision 会让 `invalidate` 选择该插件不可变的单资源 combo URL，而不是初始多资源 URL；`prefetch` 在旧 fiber 仍在服务时加载并登记新 factory。其余顺序是：`registry.delete`（在 fiber dispose（资源释放）之前执行：仅 dispose fiber 会触发 vendored Loader 的 self-dispose 分支，把配置项标为禁用）、排空旧 fiber、删除 `entry.fiber`、移除自身拥有的 `<style data-plugin>` 标签、通过 `entry.refresh()` 重新导入并挂载，最后通过 `fiber.await()` 直接重新抛出启动失败。依赖方由 Cordis 自身重载：fiber 的激活 epoch 会串联其服务提供方的 uid，因此替换提供方 fiber 会级联所有依赖方，无需客户端图分析。node 侧使用一个 interval 检测重建，以 module host 读文件前记录的基线 stat-poll 每个图 bundle 及其可选 sourcemap。未变化的启动 row 无需读取内容或求哈希即可开始监视；只有发生变化的 row，或产物恢复后的 dirty row，才会进入 `rebuilt()`，并且只广播真实 revision 变更。因此，任何生成这些产物的 tsdown watch 进程都能触发 HMR（热模块替换），无需 builder→host 通道。
+`dsh-client-hmr` 会在浏览器客户端插件的 bundle 重建后原地重载该插件，让编辑插件源码的开发者无需整页刷新即可看到变更。如果没有重建 watcher，整条链路保持空闲：只有 `pnpm run dev:web` 之类的进程重写客户端 bundle 时才会产生它所响应的重建。每次重载只替换一个插件并携带全新组件状态，而数据层（connection、runtime 与 Session 对象）保持不变。这里的一切都是浏览器侧的开发机制；模型永远看不到它。

+## 使用本包
+
+为正在编辑的插件启用重建 watcher，然后保存：浏览器会从 dev server 拾取重建后的 bundle，并在不重载页面的情况下替换该插件。在客户端开发期间使用它；在生产构建中没有任何可观察行为，因为没有 watcher 会重写 bundle。
+
+### 启动重载链路
+
+对同一个宿主运行 `pnpm run dev:web`（或任何写入插件 `lib/client.js` 的 tsdown watch 进程）；重建后的插件随后会被自动逐个替换进运行中的浏览器。
+
+### 一次重载做什么
+
+每次重载都会重新执行插件 bundle，并用全新状态重新挂载插件。依赖被重载插件的插件会随之自动重载。失败的重载会被明确报告，并在下一次重建时从头重试。
+
+### 配置
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `pollIntervalMs` | `500` | bundle stat 轮询间隔，单位为毫秒 |
+
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-client-hmr)是每个受支持字段及其 JSDoc 的穷尽式真源。
+
+### 观察成功
+
+成功的替换会立即显示编辑后的 UI，无需页面重载，且插件在替换后继续工作。请记住权衡：被重载插件内的 React 状态会丢失，而会话、工作区与连接状态会保留。

+## 理解实现
+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释重载链路的构建方式；可观察行为已在[使用本包](#use-this-package)中说明。
+
+### 设计理念
+
+链路分为两半，共用一份约定：node 半侧负责 bundle 检测与通知，浏览器半侧负责替换。node 半侧运行一个 interval，从 module host 读取文件前的基线开始 stat 轮询每个图 bundle 及其可选 source map。未变化的启动 row 无需读取内容或求 hash 即可开始监视；发生变化的 row，或产物恢复后的 dirty row，会进入 `rebuilt()`，且只广播真实 revision 变更。它还提供 `/plugins/events`，一个广播 `graph` 与 `rebuilt` 帧的 SSE 通道。
+
+### 浏览器侧替换
+
+收到 `rebuilt` 帧后，帧内 revision 会让 `invalidate` 选择该插件不可变的单资源 combo URL，而不是初始多资源 URL。`prefetch` 在旧 fiber 仍在服务时加载并注册新 factory。其余顺序是：先注册表后拆卸（在 fiber 的 disposer 发出 `internal/plugin` 之前执行 `registry.delete`，否则 vendored Loader 会把该 entry 标为禁用）、排空旧 fiber 的卸载、删除 `entry.fiber`、移除自身拥有的 `<style data-plugin>` 标签，然后 `entry.refresh()` 重新导入并挂载，`fiber.await()` 直接把启动失败重新抛出。替换之所以安全，是因为在惰性 CJS 模型下执行只是注册：每个模块副作用都位于 factory 闭包中，在物化时运行。
+
+### 级联与自重载
+
+fiber 的激活 epoch 会串联其服务提供方的 uid，因此替换提供方 fiber 会通过 cordis 自身零 HMR 簿记地级联所有依赖方。本插件本身也是一个图 entry，因此 `rebuilt` 帧可能点名它；进行中的重载在旧 bundle 的闭包中继续运行，新 bundle 的 apply 会打开全新通道。
+
+### 失败策略
+
+不回滚：导入失败会让 entry 失去 fiber（下一个 `rebuilt` 帧从头重试），apply 失败则会在外壳的状态投影中留下 FAILED fiber。两者都会大声记录日志。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | node 半侧：bundle stat 轮询、`rebuilt` 上报、`/plugins/events` SSE 通道 |

+| [`src/events.ts`](src/events.ts) | 共享帧类型（`graph` / `rebuilt`）与端点常量 |

-Locale plugin: LocaleRuntime — the preference stored as `locale.preference` in `$DSH_HOME/settings.yaml`; when that explicit Host value is absent, a fresh browser starts provisionally in the first registered language `navigator` asks for (full-tag then primary-subtag matching, with `en` when none match). The Host read runs after plugin activation so an unavailable settings service cannot block the page; its result replaces the provisional browser value live. A saved external locale waits for its definition to register rather than becoming active while unavailable. The Client keeps Host settings persistence disabled on non-loopback pages, so their locale selection remains process-local even though Connection authenticates every API method. `locale/change` fires on switches, and the plugin points `<html lang>` at the external language id or the built-in language's document tag on activation and on every switch. Product-authored Client UI text must enter through these typed dictionaries or an already-localized primitive prop; `verify-client-ui-i18n` enforces that source ownership ([decision](../../../.agents/notes/implemented/architecture/2026-08-23-locale-owned-client-ui-copy.md)). The [Host-backed preferences decision](../../../.agents/notes/implemented/bug-fix/2026-08-06-host-backed-web-preferences.md) owns the persistence boundary.
+## Summary
 
-The package ships only `zh` and `en`. External client plugins add a selectable language with `ctx.effect(() => ctx.locale.addLanguage({ id, label, fallback }))` and add its dictionaries through the existing `register(ns, locale, dict)` form; definitions and dictionaries may register in either order. Unloading the definition removes it from the selector and returns an active selection to the available browser/default locale. An external id is a non-empty ASCII BCP 47-style tag used for persistence, dictionary lookup, browser matching, and `<html lang>`. Its fallback must already be registered, and the resulting chain must terminate at `en`; unknown targets, duplicate ids, and cycles fail at registration. For each key, lookup walks the chain in the requested namespace, repeats it in `common`, then displays the key. The typed `register(ns, { zh, en })` form remains checked against `LocaleNamespaceMap` and requires both built-in dictionaries. LocaleRuntime implements the slot system's `LocaleFace` and installs itself through `ctx.slots.installLocale`, backing the framework-injected `t` standard seat (`Translate`/`TranslateNS` are ui-slots types; import them from there — this package only re-exports them for dictionary owners).
+`dsh-client-locale` localizes the web GUI: users choose from the registered languages in Settings → General, and the UI copy switches immediately. The package ships `zh` and `en`, while external client plugins can add languages and their namespace dictionaries. On a loopback page, the choice persists as `locale.preference` in `$DSH_HOME/settings.yaml`; a non-loopback page keeps its selection process-local even though Connection authenticates every API method. A fresh browser starts provisionally in the first registered language requested by `navigator` until an allowed Host preference arrives and replaces it live. Plugin authors receive full type checking for the built-in dictionary form and translate through the framework `t` seat; copy rendered through slots follows language switches without a reload.

+## Use this package
+
+Use it wherever the web GUI needs a language switch or translated copy: the shipped settings row covers users, and plugin authors register their own dictionaries. Nothing needs configuration to mount — the package activates with the client tree.
+
+### Choosing a language
+
+Open Settings → General and select a registered language. The active locale is applied immediately: the UI copy switches, `<html lang>` points at the external id or built-in document tag, and the choice is written to the durable settings section. A browser without an explicit Host preference selects the first registered language that matches `navigator` by full tag and then primary subtag, falling back to English. A stored external locale waits for its definition to register instead of becoming active while unavailable.
+
+### Registering a dictionary
+
+Call `ctx.locale.register(ns, { zh, en })` with a namespace merged into `LocaleNamespaceMap`; the compiler checks every key against the namespace's typed key union and requires both shipped locales. Consumers translate through `ctx.locale.bind(ns)` or the framework-injected `t` seat. A dictionary registered after the UI is already mounted is picked up without a remount.
+
+### Registering a language pack

+
+This section explains how the locale service is built; observable behavior is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+One `LocaleRuntime` owns the preference and the dictionary registry, and is itself the slot system's `LocaleFace`: `getSnapshot`/`subscribe` back the framework-injected `t` seat through `ctx.slots.installLocale`. The immutable snapshot carries the active locale, the selectable locales, and a monotonic revision; dictionary registration and locale switches both advance the revision, but only a switch emits the `locale/change` event. Product-authored Client UI text must enter through these typed dictionaries or an already-localized primitive prop; `verify-client-ui-i18n` enforces that source ownership ([decision](../../../.agents/notes/implemented/architecture/2026-08-23-locale-owned-client-ui-copy.md)).
+
+### Preference resolution
+
+The provisional locale comes from the browser (`navigator.languages` matched by full tag and then primary subtag, English as the fallback), standing in until the allowed Host-backed settings scope delivers its stored preference. The Host read runs after plugin activation so an unavailable or withheld settings scope cannot block the page, and the result replaces the provisional value live. A stored external locale waits for its definition to register. `setLocale` is the only write entry; it persists even when the id already matches the active locale, because the active value may be provisional and must survive a different browser sharing the same home.
+
+### Dictionary lookup
+
+The typed object form requires complete dictionaries for both built-in locales. The per-locale form lets language packs register each namespace independently. For each key, lookup walks the active language's declared fallback chain in the requested namespace, repeats that chain in `common`, then displays the key itself. Bound translate functions retain stable identity per namespace so they can ride inject surfaces without breaking memoization.

-locale 插件：LocaleRuntime——偏好以 `locale.preference` 存储在 `$DSH_HOME/settings.yaml` 中；若没有显式 Host 值，全新浏览器会暂时使用 `navigator` 请求的第一个已注册语言（先匹配完整标签，再匹配主子标签；若都不匹配，则使用 `en`）。Host 读取在插件激活后执行，因此 settings 服务不可用不会阻塞页面；读取结果会实时替换浏览器暂定值。已保存但尚未注册定义的外部 locale 会等待该定义注册，不会在不可用时成为当前语言。Client 在非 loopback 页面禁用 Host settings 持久化，因此这些页面的 locale 选择仍只保留在进程内，尽管 Connection 会认证每个 API 方法。`locale/change` 仅在切换语言时触发；插件会在激活时以及每次切换时把 `<html lang>` 指向外部语言 id 或内置语言的文档标签。产品编写的 Client UI 文本必须经这些 typed 字典或已本地化原子组件 prop 进入展示；`verify-client-ui-i18n` 会强制这项源码归属（[决策](../../../.agents/notes/implemented/architecture/2026-08-23-locale-owned-client-ui-copy.zh.md)）。该持久化边界由[Host settings 支撑的偏好决策](../../../.agents/notes/implemented/bug-fix/2026-08-06-host-backed-web-preferences.zh.md)拥有。
+## 概述
 
-本包只内置 `zh` 与 `en`。外部 client 插件通过 `ctx.effect(() => ctx.locale.addLanguage({ id, label, fallback }))` 增加可选语言，并通过既有 `register(ns, locale, dict)` 形式增加该语言的字典；定义与字典可以按任意顺序注册。定义卸载后，它会从选择器移除，正在使用的选择则回落到当前可用的浏览器语言或默认语言。外部 id 是用于持久化、字典查找、浏览器匹配和 `<html lang>` 的非空 ASCII BCP 47 风格标签。其 fallback 必须已注册，形成的链必须终止于 `en`；未知目标、重复 id 和循环会在注册时失败。每个 key 先在请求的命名空间中沿链查找，再在 `common` 中重复该链，最后显示 key。类型化 `register(ns, { zh, en })` 形式仍按 `LocaleNamespaceMap` 检查，并要求两份内置字典。LocaleRuntime 实现 slot 系统的 `LocaleFace`，并经 `ctx.slots.installLocale` 自行安装，支撑框架注入的 `t` 标准席位（`Translate`／`TranslateNS` 是 ui-slots 的类型；请从那里导入——本包的再导出仅供字典所有者使用）。
+`dsh-client-locale` 为 web GUI 提供本地化：用户在“设置 → 常规”中从已注册语言中选择，UI 文案会立即切换。本包内置 `zh` 与 `en`，外部 client 插件可以增加语言及其命名空间字典。在 loopback 页面上，该选择以 `locale.preference` 存储在 `$DSH_HOME/settings.yaml` 中；非 loopback 页面即使由 Connection 认证所有 API 方法，也只在进程内保留选择。全新浏览器会先临时使用 `navigator` 请求的第一个已注册语言，直到允许读取的 Host 偏好到达并实时替换。插件作者使用内置字典形式时会获得完整类型检查，并通过框架 `t` 席位翻译；经 slot 渲染的文案会随语言切换即时更新。

+## 使用本包
+
+只要 web GUI 需要语言切换或翻译文案就使用它：已发布的设置行覆盖用户侧，插件作者则注册自己的词典。挂载无需任何配置——本包随客户端树一起激活。
+
+### 选择语言
+
+打开“设置 → 常规”并选择一种已注册语言。生效中的 locale 会立即应用：UI 文案切换、`<html lang>` 指向外部 id 或内置语言的文档标签，选择写入持久设置分区。没有显式 Host 偏好的浏览器会按完整标签、再按主子标签选择 `navigator` 请求的第一个已注册语言，无法匹配时回退到 English。已存储的外部 locale 会等待其定义注册，不会在不可用时生效。
+
+### 注册词典
+
+用已合并进 `LocaleNamespaceMap` 的命名空间调用 `ctx.locale.register(ns, { zh, en })`；编译器会对照该命名空间的类型化键并集检查每个键，并要求两个内置 locale 齐全。消费方通过 `ctx.locale.bind(ns)` 或框架注入的 `t` 席位翻译。UI 已挂载后再注册的词典无需重新挂载即可生效。
+
+### 注册语言包
+
+外部 client 插件把语言定义和每个已翻译命名空间注册为自身拥有的 effect；定义与字典可以按任意顺序注册：
 
 ```js
 export const inject = ['locale']
@@ -28,15 +57,84 @@ export function apply(ctx) {
 }
 ```
 
+外部 id 必须是非空的 ASCII BCP 47 风格标签。它的 fallback 必须已经注册，且整条链必须终止于 `en`；未知目标、重复 id 与循环会在注册时失败。查找时先在请求命名空间内遍历生效语言的 fallback 链，再在 `common` 中遍历该链，最后显示键本身。卸载语言定义会将其从选择器移除，并让生效中的选择回落到可用的浏览器语言或默认语言。
+
+### Host 半侧做什么
+
+Host 通过 settings 服务为 loopback 页面持久化偏好。Client 会刻意拒绝非 loopback 页面使用该 settings scope，因此即使 Connection 认证所有 API 方法，它们的 locale 选择仍只存在于进程内。

+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释 locale 服务的构建方式；可观察行为已在[使用本包](#use-this-package)中说明。
+
+### 设计理念
+
+一个 `LocaleRuntime` 同时拥有偏好与词典注册表，并且自身就是 slot 系统的 `LocaleFace`：`getSnapshot`／`subscribe` 通过 `ctx.slots.installLocale` 支撑框架注入的 `t` 席位。不可变快照携带生效中的 locale、可选择的 locale 列表与单调 revision；词典注册与 locale 切换都会推进 revision，但只有切换会发出 `locale/change` 事件。产品编写的 Client UI 文本必须来自这些带类型的字典，或来自已经本地化的 primitive prop；`verify-client-ui-i18n` 强制执行该源码归属（见[决策](../../../.agents/notes/implemented/architecture/2026-08-23-locale-owned-client-ui-copy.zh.md)）。
+
+### 偏好解析
+
+临时 locale 来自浏览器（`navigator.languages` 先按完整标签、再按主子标签匹配，以 English 作为回退），在允许使用的 Host-backed settings scope 送达其存储偏好之前生效。Host 读取在插件激活后运行，因此 settings scope 不可用或被拒绝都不会阻塞页面，结果会实时替换临时值。已存储的外部 locale 会等待其定义注册。`setLocale` 是唯一写入入口；即使 id 已与生效中的 locale 匹配也会持久化，因为生效中的值可能是临时的，必须能在共享同一 home 的其他浏览器上存活。
+
+### 词典查找
+
+带类型的对象形式要求两个内置 locale 都有完整字典；逐 locale 形式允许语言包独立注册每个命名空间。逐键查找会先在请求命名空间中沿生效语言声明的 fallback 链查找，再在 `common` 中重复该链，最后显示键本身。绑定的翻译函数按命名空间保持稳定身份，因此可以挂在 inject 表面上而不破坏 memoization。

-Client module system: the browser peer of Node's internal ESM loader, built as a lazy CJS table. The web shell mounts the vendored cordis Loader for entry governance (fiber lifecycle, inject waiting, update/refresh) and injects this package's `ClientModuleLoader` through its `internal` contract — the vendored side's only consumption point is `EntryTree.import`, so replacing `internal` replaces exactly "how plugin code arrives" and nothing else.
+## Summary
 
-Lazy CJS model (web2): executing a plugin bundle only REGISTERS its factory (`window.__ModuleLoader__.load({id, factory})`); every module body side effect — CSS injection included — lives in the factory closure and runs at materialization (`factory(require)` → exports, memoized in `loadCache`), not at script execution. A factory that requires another registered-but-unmaterialized module materializes it recursively; graph composition places declared dynamic requests before their consumers, and require cycles throw because factory-form CJS cannot deliver partial exports. `<id>/client` and the bare id resolve to the same exports (a plugin bundle IS its package's client half).
+`dsh-client-modules` turns a plugin package's `dsh.client` declaration into a loadable browser bundle: the host half scans enabled Loader entries, composes the boot graph, and serves each bundle over `/plugins`, and the browser half loads those bundles lazily on demand. Plugin bundles execute lazily — running a bundle only registers a factory, and module side effects run at materialization — so nothing runs until a plugin is first used. Everything here is browser-kernel machinery; the model never sees it.
 
-The Host installs `window.__ModuleLoader__`, preloads every application combo script, then executes the parser-blocking bootstrap combo scripts. `bootstrap` and `application` are scheduling phases, not URL path names, and either phase may span several requests. Queue-mode `load()` retains the modules registration; `create()` materializes this package's factory with an external-rejecting bootstrap require and calls its `createClientModuleSystem` export. Construction caches those same exports as the modules row and switches the same facade to live registration. The bundle retains the resulting system in a module closure, so its later Cordis `apply()` provides the identical instance as `ctx.modules` without another page global.
+## Table of Contents
 
-Resolution branch order (`import(specifier)`): platform seed word → shell instance; memoized record → exports; graph row (`window.__DSH_BOOT__`) → register its initial-combo factory; registered factory → materialize; anything else throws — the runtime mirror of the build-time bundle purity gate. The synchronous `require` handed to factories walks the same order minus the asynchronous graph-row load and records observed edges into the module record. `prefetch` is the stage-one arrival hook; rows sharing an initial combo URL share one in-flight script task. `invalidate(id, rev)` drops a non-bootstrap factory and materialized record and switches that row to its revisioned one-resource combo URL, so HMR reloads one plugin without executing the initial multi-resource script again.

-The Node half scans enabled Loader entries for web `dsh.client` packages, resolves and snapshots each `exports["./client"]` plus its available source map, carries package-specific `dsh.client.external` requests, and orders dynamic providers before consumers. It schedules the modules row as bootstrap and every other row as application. Both initial delivery and HMR use the same combo route: `/plugins/??<package-a>/client.js,<package-b>/client.js&rev=<rev>` for any non-empty resource list, including a one-resource HMR reload. Within each phase, graph composition greedily partitions the ordered resources before the longer map-form URL would exceed 3 KiB, so a large application uses several requests without changing the path model. A script's absolute `sourceMappingURL` mirrors its list as `/plugins/??<package-a>/client.js.map,<package-b>/client.js.map&rev=<rev>`. Every generated map is Indexed Source Map v3. An authored plugin map supplies its section; otherwise an identity section embeds the generated bundle and names its packaged `lib/client.js` when available, so one combo remains separable into its component files. Initial per-plugin revisions are opaque process nonces, so startup does not hash every plugin; HMR hashes only an artifact whose watcher reports a change. Every advertised response is immutable, and an unadvertised combination or revision returns 404 instead of serving different bytes. Source launch maps host imports to TypeScript source but still consumes these built client exports; missing files share one build instruction followed by a package/path list, while unrelated filesystem errors remain separate failures.
+-----
 
-`dsh.client.external` is an optional exact-specifier request list beyond the implicit baseline of shell-seeded React, Cordis, and static UI libraries. A request is answered by the dynamic package row it names or an exact static-table key; only a trailing `/client` aliases a package row, and there is no provider-alias declaration. Type-only imports are erased and create no request. Composition rejects malformed requests, missing suppliers, self-requests, and synchronous request cycles; import and prefetch recursively register dynamic suppliers before their consumers materialize. See [shared modules and the module graph](../AGENTS.md#shared-modules-and-the-module-graph).
+<a id="use-this-package"></a>
+## Use this package
 
+Use it when you compose or build a browser client plugin: the package turns a package's `dsh.client` declaration into a loadable browser bundle with no per-plugin wiring. It activates with the web composition; the shell boots it before any plugin runs.
+
+### Declaring a client plugin
+
+A browser plugin package declares `dsh.client` in its `package.json` with `platform: 'web'`, exports a `./client` bundle, and lists any non-baseline module requests under `dsh.client.external`. The host half turns each declaration into a served bundle under `/plugins`, ordered so dynamic providers load before their consumers.
+
+### What the browser loads
+
+The application combo scripts register plugin factories once during boot; module bodies remain lazy and run only at first import or materialization. Rows that share a combo URL share one in-flight script task. HMR switches one changed row to its revisioned one-resource combo URL. `<id>/client` and the bare id resolve to the same exports, because a plugin bundle is its package's client half.
+
+### Sharing modules
+
+The shell seeds a frozen module table (`PLATFORM_MODULES`: React, Cordis, and static UI libraries); every dynamic bundle resolves its externals against exactly that baseline. `dsh.client.external` adds only exact non-baseline requests, each answered by the dynamic package row it names or an exact static-table key. Type-only imports are erased and create no request. Composition rejects malformed requests, missing suppliers, self-requests, and synchronous request cycles.
+
+### Build requirements
+
+The host serves built client bundles, so `pnpm run build` must have produced each `lib/client.js` before launch; a missing bundle fails activation loudly with one build instruction and a package/path list. Source launch maps host imports to TypeScript source but still consumes the built client export. The package accepts no plugin config of its own.
+

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the module system is built; observable behavior is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The package is dual-face: the node half is the composition and serving side (`ctx.clientModules`, `ClientModuleRegistry`), the browser half is the loading side (`ctx.modules`, `ClientModuleSystem`). The wire between them is the boot graph — `WebBootEntry` rows injected as `window.__DSH_BOOT__`, with `<` escaped so plugin-controlled strings cannot break out of the script element. The vendored Loader's only consumption point is `EntryTree.import`, so the module system is the single replacement for "how plugin code arrives".
+
+### Lazy-CJS model
+
+Executing a plugin bundle only registers its factory; every module-body side effect (CSS injection included) lives in the factory closure and runs at materialization (`factory(require)` → exports, memoized in `loadCache`). A factory that requires another registered-but-unmaterialized module materializes it recursively; require cycles throw because factory-form CJS cannot deliver partial exports. Resolution checks the platform seed table, memoized records, boot-graph rows, and registered factories in that order; anything else throws. The synchronous `require` uses the same order without asynchronous graph-row loading and records observed edges into the module record.
+
+### Incremental composition
+
+The node half scans incrementally per package — no full-rescan path. Every `internal/plugin` emission marks the fiber's entry name dirty; a microtask flush reconciles each dirty name against the live loader entries, and the activation pass seeds the same dirty set and flushes synchronously, so first scan and steady state share one implementation. Package metadata is cached per name and never expires; bundle content changes reach the graph only through `rebuilt()` (the HMR hook).
+
+The node half snapshots each client bundle and available source map before publication. It groups resources into `/plugins/??...&rev=...` combo URLs, with one bootstrap combo for the modules row and one or more application combos for the other rows; each phase is partitioned before a URL exceeds 3 KiB. Every combo map is Indexed Source Map v3 and uses an authored section when available or an identity section for the packaged bundle. Initial per-plugin revisions use process nonces, so startup does not hash every plugin; HMR hashes only an artifact reported as changed. Advertised responses are immutable, and an unknown combination or revision returns 404.
+
+### Boot manifest injection
+
+The host taps the index render and injects, into `<head>`: the `window.__ModuleLoader__` queue facade, advisory preloads for every application combo, the parser-blocking bootstrap combo scripts, then the boot graph before the shell reads it. The facade's `create()` materializes the modules bundle, delegates construction to its `createClientModuleSystem` export, and leaves the same facade in live-registration mode.

+
+
+These limits define what the module system does not do. They are current package constraints, not a task backlog.
+
 - **Flat module graph by design** — every bundle is one module node whose edges point only at table leaves; the interface (`loadCache`/`edges`/`invalidate`) already supports a general module graph, so the externalization granularity can change without an interface change.
 - **No unload bookkeeping of its own** — style removal and fiber teardown ordering live with the HMR driver (`@deepseek-ai/dsh-client-hmr`); the loader only inventories owned style tag ids per record.
 - **Snapshot delivery retains artifact bytes** — the Host holds each bundle, optional source map, generated one-resource response, and current startup combo responses in memory; HMR additionally retains one prior startup generation. Memory scales as several copies of the composed client artifacts in exchange for immutable responses and one-generation race tolerance.

 [English](README.md) | 中文
 
-客户端模块系统：Node 内部 ESM loader 的浏览器端对等实现，以惰性 CJS 表实现。web 外壳挂载 vendored cordis Loader 来治理配置项（fiber 生命周期、inject 等待、update/refresh），并通过其 `internal` 约定注入该包的 `ClientModuleLoader`；vendored 一侧唯一的消费点是 `EntryTree.import`，因此替换 `internal` 恰好只会替换「插件代码如何到达」，不会改变其他内容。
+## 概述
 
-惰性 CJS 模型（web2）：执行插件 bundle 只会注册其 factory（`window.__ModuleLoader__.load({id, factory})`）；每个模块主体的副作用（包括 CSS 注入）都位于 factory 闭包中，在物化时运行（`factory(require)` → 导出表层，并在 `loadCache` 中记忆化），不会在脚本执行时运行。如果 factory 依赖另一个已注册但尚未物化的模块，系统会递归物化它；图组合会把声明的动态请求提供方放在消费者之前，而 require 循环会抛出异常，因为 factory 形式的 CJS 无法提供部分导出。`<id>/client` 与裸 id 指向同一表层（一个插件 bundle 就是其包的客户端侧）。
+`dsh-client-modules` 把插件包的 `dsh.client` 声明变成可加载的浏览器 bundle：宿主半侧扫描已启用的 Loader 条目、组合启动图，并通过 `/plugins` 提供每个 bundle；浏览器半侧按需惰性加载这些 bundle。插件 bundle 惰性执行——运行 bundle 只注册 factory，模块副作用在物化时运行——因此插件首次被使用之前什么都不会运行。这里的一切都是浏览器内核机制；模型永远看不到它。
 
-Host 会先安装 `window.__ModuleLoader__`、预加载所有 application combo 脚本，再执行阻塞 parser 的 bootstrap combo 脚本。`bootstrap` 与 `application` 只是调度阶段，不会成为 URL 路径名，并且每个阶段都可以包含多次请求。Queue 模式的 `load()` 保存 modules registration；`create()` 使用拒绝 external 的 bootstrap require 物化本包 factory，并调用其 `createClientModuleSystem` 导出。构造过程把同一组导出缓存为 modules row，并把同一个 facade 切换到 live registration。Bundle 通过模块闭包保留生成的系统，因此随后 Cordis `apply()` 能把同一实例提供为 `ctx.modules`，无需另一个页面全局变量。
+## 目录
 
-解析分支顺序（`import(specifier)`）：平台种子词 → 外壳实例；记忆化记录 → 导出；模块图记录（`window.__DSH_BOOT__`）→ 登记其初始 combo 中的 factory；已登记 factory → 物化；其他情况一律抛出异常。这是构建时 bundle 纯度门禁的运行时镜像。交给 factory 的同步 `require` 采用相同顺序，但不含异步 graph-row 加载分支，并把观察到的边记录到模块记录中。`prefetch` 是第一阶段到达钩子；共享同一初始 combo URL 的 row 会共享一个进行中的脚本任务。`invalidate(id, rev)` 会丢弃非 bootstrap factory 与物化记录，并让该 row 改用带 revision 的单资源 combo URL，因此 HMR（热模块替换）只重载一个插件，不会再次执行初始多资源脚本。

-Node 侧会扫描已启用的 Loader 配置项以发现 web `dsh.client` 包，解析并快照每个 `exports["./client"]` 及其可用 sourcemap，携带包专属 `dsh.client.external` 请求，并把动态提供方排在消费者之前。它把 modules row 调度为 bootstrap，把其余 row 调度为 application。初始传输与 HMR 使用同一条 combo 路由：任意非空资源列表都写成 `/plugins/??<package-a>/client.js,<package-b>/client.js&rev=<rev>`，HMR 单资源重载也不例外。图组合会在更长的 map 形式 URL 超过 3 KiB 前，按顺序贪心切分每个阶段的资源，因此大型 application 会产生多次请求，但路径模型不变。脚本中的绝对 `sourceMappingURL` 把各自的资源列表平行改写成 `/plugins/??<package-a>/client.js.map,<package-b>/client.js.map&rev=<rev>`。每个生成的 map 都是 Indexed Source Map v3：插件有自带 map 时直接用于对应 section；没有时则生成 identity section，内嵌构建后 bundle，并在存在打包路径时命名为其 `lib/client.js`，因此一个 combo 仍能拆回各组件文件。初始逐插件 revision 使用不透明的进程 nonce，因此启动时不会哈希每个插件；HMR 只哈希 watcher 报告发生变化的产物。每个已发布响应都不可变，未发布的组合或 revision 返回 404，绝不提供其他字节。源码启动会把宿主侧导入映射到 TypeScript 源码，但仍消费这些构建后的客户端导出；缺失文件共享一条构建说明，随后以包／路径列表列出各项，而无关的文件系统错误仍是独立故障。
+-----
 
-`dsh.client.external` 是外壳播种的 React、Cordis 和静态 UI 库这一统一基座之外的可选精确 specifier 请求列表。请求由其命名的动态 package row 或精确静态表键回答；只有末尾 `/client` 会别名到 package row，并且不存在 provider 别名声明。纯类型 import 会被擦除，不产生请求。组合阶段会拒绝畸形请求、缺失提供方、自请求和同步请求环；import 与 prefetch 会在消费者物化前递归登记动态提供方。参见[共享模块与模块图](../AGENTS.md#shared-modules-and-the-module-graph)。

+## 使用本包
 
+组合或构建浏览器客户端插件时使用它：本包把包的 `dsh.client` 声明变成可加载的浏览器 bundle，无需任何逐插件接线。它随 web 组合激活；外壳在任何插件运行前启动它。
+
+### 声明客户端插件
+
+浏览器插件包在其 `package.json` 中以 `platform: 'web'` 声明 `dsh.client`，导出 `./client` bundle，并在 `dsh.client.external` 下列出任何基座之外的模块请求。宿主半侧把每份声明变成 `/plugins` 下提供的 bundle，并让动态提供方先于其消费方加载。
+
+### 浏览器加载什么
+
+application combo 脚本在启动时注册插件 factory；模块主体仍保持惰性，只在首次 import 或物化时运行。共享 combo URL 的 row 共用一个进行中的脚本任务。HMR 会让一条发生变化的 row 改用带 revision 的单资源 combo URL。`<id>/client` 与裸 id 解析到同一组导出，因为插件 bundle 就是其包的客户端半侧。
+
+### 共享模块
+
+外壳播种一张冻结模块表（`PLATFORM_MODULES`：React、Cordis 与静态 UI 库）；每个动态 bundle 都精确针对该基座解析其 external。`dsh.client.external` 只添加基座之外的精确请求，每个请求由其命名的动态包 row 或精确静态表键回答。纯类型 import 会被擦除，不产生请求。组合阶段会拒绝畸形请求、缺失提供方、自请求与同步请求环。
+
+### 构建要求
+
+宿主提供的是已构建的客户端 bundle，因此启动前 `pnpm run build` 必须已产出每个 `lib/client.js`；缺失 bundle 会以一条构建说明加包／路径列表的方式让激活大声失败。源码启动会把宿主侧导入映射到 TypeScript 源码，但仍消费这一构建后的客户端导出。本包自身不接受任何插件配置。

+执行插件 bundle 只注册其 factory；每个模块主体副作用（包括 CSS 注入）都位于 factory 闭包中，在物化时运行（`factory(require)` → 导出，在 `loadCache` 中记忆化）。factory 依赖另一个已注册但未物化的模块时会递归物化它；require 循环会抛出异常，因为 factory 形式的 CJS 无法提供部分导出。解析会依次检查平台 seed 表、已记忆记录、启动图 row 与已注册 factory；其他情况一律抛错。交给 factory 的同步 `require` 使用相同顺序，但不含异步图 row 加载，并把观察到的边记录到模块记录中。
+
+### 增量组合
+
+node 半侧逐包增量扫描——没有全量重扫路径。每次 `internal/plugin` 发出都会把该 fiber 的 entry 名标脏；一个微任务 flush 会把每个脏名与当前 loader 条目对账，激活 pass 播种同一脏集合并同步 flush，因此首次扫描与稳态共用同一实现。包元数据按名缓存且永不过期；bundle 内容变更只能通过 `rebuilt()`（HMR 钩子）进入图。
+
+node 半侧会在发布前快照每个客户端 bundle 及其现有 source map。它把资源分组到 `/plugins/??...&rev=...` combo URL：modules row 使用一个 bootstrap combo，其余 row 使用一个或多个 application combo；每个阶段都会在 URL 超过 3 KiB 之前分区。每个 combo map 都是 Indexed Source Map v3，并在可用时使用作者提供的 section，否则为已打包 bundle 生成 identity section。初始逐插件 revision 使用进程 nonce，所以启动时不哈希每个插件；HMR 只哈希被报告为已变化的产物。已公告响应不可变；未知组合或 revision 返回 404。
+
+### 启动清单注入
+
+宿主 tap 索引渲染，并向 `<head>` 注入：`window.__ModuleLoader__` queue facade、每个 application combo 的提示性 preload、阻塞 parser 的 bootstrap combo 脚本，然后才是外壳读取前的启动图。facade 的 `create()` 物化 modules bundle、把构造委托给其 `createClientModuleSystem` 导出，并让同一 facade 进入 live registration 模式。

-The agent-preset surfaces: a General-settings row choosing which [preset](../../preset/agent-presets/README.md) new sessions are composed from, a chip on the new-session screen choosing the next session's, a read-only label in the session header, and a settings section that manages the roster — copy, delete, default, and the way into a preset's own files.
+## Summary
 
-## Why it is a new-session preference
+This package provides the agent-preset surfaces of the Web GUI: a General-settings row choosing which preset new sessions are composed from, a chip on the new-session screen choosing the next session's preset, a read-only label in the session header, and a settings section that manages the roster — copy, delete, default, and the way into a preset's own files. A session's preset is fixed at creation, so the choice applies to sessions started afterwards while running sessions keep the composition they began with. When a deployment composes no presets, all four surfaces render nothing and every session shares the host composition.
 
-A session's preset is fixed when the session is created — the host refuses to adopt an existing session under a different one, because that session's history was produced under the first preset's tools. So this row cannot be a live switch, and it says so: changing it applies to sessions started afterwards while running sessions keep the composition they began with.

-A second surface, beside the workspace picker on the new-session screen. It sits there rather than in the composer because that is where the choice is still open: a control that spends most of its life disabled belongs on the screen where it still works.
+-----
 
-The chip opens on the deployment default and its pick is *staged* — the screen precedes the session it would apply to. The stage reaches a session when one becomes current and is still blank, which covers both the session the workspace connect created and the blank one it reused; riding along on `sessions.create` would miss the second. It is spent on first use, so the next new session opens on the default again, exactly like the workspace picker beside it.
+<a id="use-this-package"></a>
+## Use this package
 
-A session that has started is refused rather than queued: the host answers `agent-preset-locked`, and the stage is dropped instead of waiting for a session that will never accept it.
+Mount this plugin alongside the settings and conversation packages; the preset surfaces then appear where their slots render. The General-settings row opens on the deployment default and applies to sessions started afterwards; the new-session chip stages a pick that lands on the next blank session and is spent on first use, so the following new session opens on the default again.
 
-## The session-header label
+### Managing the roster
 
-A third surface, beside the session title: the preset THIS session runs, as static chrome. A control there would promise a switch the host refuses outright. It reads the preset from the session's own summary and resolves the display name against the same roster the General row reads. Forwarded `agent-preset/selected` owner events fold committed blank-session switches into that shared summary in every tab; the initiating tab may already have applied the RPC echo, and the merge is idempotent.
+The settings section shows the roster as cards: a copy dialog is the only way a preset is created — the browser edits no composition text — and every custom card keeps a location action that opens the preset's own files. The default is set from any surface; deleting removes the preset directory while sessions already composed from it keep running. A shipped preset opens in a read-only viewer and offers no location or delete. A roster row carrying `broken` renders as a marked card whose body and duplication are disabled, because a copy of a broken preset is another broken preset; broken custom rows keep their location and delete actions so the files can be fixed and ghost directories cleared.
 
-## What it reads and writes
+### The conversational entry
 
-Options and the current default both come from one `agentPreset.list` call. The roster already reports which id a session with no explicit choice gets, so the row needs no settings-schema introspection; the write targets the `agent-presets` settings namespace's `default` field, which is what the host resolves at creation.
+When the roster carries the self-referential `cordis` preset, a dashed add-card stages it and starts a new session — the section closes the settings panel and the new-session chip's own applier composes the blank session the workspace flow produces.
 
-A locally authored preset is exactly as privileged as the plugins it names, so the list marks `user` rows rather than presenting every preset as shipped and vetted.
+-----
 
-Preset files publish one unlocalized `name` and `description`, which Web uses for every `user` row and unknown `system` row. For the four shipped ids (`standard`, `code`, `minimal`, and `cordis`), Web resolves both fields from its active locale only when the roster marks the row `system`; an identically named `user` preset keeps its file metadata.
+<a id="understand-the-implementation"></a>
+## Understand the implementation
 
-The row re-reads on `settings/changed` for its own namespace and on `connection/reset`: the roster is a live directory and the default is a settings field, so an external edit or a reconnect can both move it.
+<details>
+<summary>Implementation internals — click to expand</summary>
 
-## The management section
+Options and the current default both come from one `agentPreset.list` call — the roster already reports which id a session with no explicit choice gets, so the row needs no settings-schema introspection — and the write targets the `agent-presets` settings namespace's `default` field, which is what the host resolves at creation. The new-session chip and the header label share one controller, because the staged choice belongs to the flow rather than to any one session; the stage is applied when a session arrives (covering both the session a workspace connect created and the blank one it reused) and dropped on refusal. [`dsh-client-connection`](../connection/README.md) authenticates `agentPreset.read`, `copy`, `openDocument`, `remove`, `list`, and every other Host API method with the same browser session. A composition still names the plugins a session runs, so reading one is reconnaissance, while copy, remove, and openDocument manage the roster and drive the host desktop. The section re-reads on its own actions, `settings/changed`, and `connection/reset`, because composition files are edited outside the browser and nothing on the wire announces a file change.
 
-A fourth surface, its own settings page (`settings.section` id `agent-presets`, ordered after Models — choosing a model is routine, composing an agent is the deployment-shaping act behind it): the roster as cards, a copy dialog as the only way a preset is created, and a read-only viewer over the shipped compositions.
+</details>
 
-The browser edits no composition text. Editing YAML in a web textarea was a weak surface (no completion, no highlighting, no diff), so a new preset is a host-side copy of an existing one — the dialog collects an id (it becomes the directory name, which is why it must be named up front and cannot change later) and an optional display name, and `{ from, id, name? }` is all that crosses the wire. Everything else — description, composition, skills — is edited in the preset's own files, and the page's other job is getting the user TO those files: the copy completes by opening the new directory, and every custom row keeps a location action. Where the host has no desktop opener (`hasDocument: false` on the roster; remote and container deployments), the same actions answer the directory as text on the row instead of offering a button that would spawn into nothing.
+-----
 
-A preset publishes its own description, of any length, and the grid sizes every card row alike — so an unbounded description would set the height of the whole roster. Cards clamp it to four lines and offer the rest in a tooltip, attached only while the text is actually cut off. The clamp is CSS, so the whole description stays in the accessibility tree whatever the card shows.
+<a id="further-exploration"></a>
+## Further Exploration
 
-A shipped preset opens in the read-only viewer. It is the known-good composition a copy starts from, so reading it is the point; it offers no location and no delete — its install is overwritten by upgrades and is not the user's to manage. The intro tells users to duplicate an existing preset and make it theirs, or let the agent draft one in Creator mode.
+Read these pages when the preset surface is not enough. They move from the browser surfaces to the preset domain and the composition model.
 
-Beside copying sits the conversational entry: when the roster carries the self-referential `cordis` preset, a dashed add-card (the Models page's affordance) stages it and starts a new session — the section closes the settings panel through the shell's owner-prop `close` and the new-session chip's own applier composes the blank session the workspace flow produces. The seat keeps a late roster load from regressing the display: staged pick first, then the composition the current session already carries, then the deployment default.
+- [dsh-agent-presets](../../preset/agent-presets/README.md) — the host roster and composition the surfaces read and manage.
+- [ui-conversation](../ui-conversation/README.md) — declares the hero and session-header slots the chip and label fill.
+- [ui-settings](../ui-settings/README.md) — the settings shell that hosts the General row and the roster section.
+- [Client package map](../README.md) — adjacent browser UI packages.
 
-The dialog mirrors the host's own containment rule (`[a-z0-9][a-z0-9-]*`) and refuses a name already in use — a copy never overwrites. Both checks are conveniences: the host re-applies them and its answer is what the dialog reports on failure.
-
-Deleting removes the preset directory. Sessions already composed from it keep running — a composition is mounted once at session creation and nothing re-reads the file.
-
-A roster row carrying `broken` (the host's shape check found the composition missing or unloadable) renders as a marked card: red border, a "Failed to load" badge (what discovery observed, not a claim that the files are damaged — the usual cause is a composition the user just edited or deleted), the reason verbatim, the body disabled — it cannot become the default — and duplication disabled, since a copy of a broken preset is another broken preset. A broken custom row keeps its location and delete actions, because the files are where it gets fixed and deleting is how a ghost directory (composition deleted by hand, directory still blocking the id) is cleared; a broken shipped row withholds the viewer too — there is no readable composition to show. The two pickers (the General row and the new-session chip) drop broken presets entirely: they choose the NEXT session's composition, and offering one that cannot compose would only defer the failure to the session start.
-
-Setting the default writes the `agent-presets` settings namespace, which the host exposes to configuration clients ([`dsh-apiproxy`](../../host/apiproxy/README.md) keeps an explicit allowlist — a namespace outside it makes a picker move and then silently forget).
-
-[`dsh-client-connection`](../connection/README.md) authenticates `agentPreset.read`, `copy`, `openDocument`, `remove`, `list`, and every other Host API method with the same browser session. A composition still names the plugins a session runs, so reading one is reconnaissance, while copy/remove/openDocument manage the roster and drive the host desktop.
-
-## When the surfaces are absent
-
-A deployment that composes no presets answers with an empty roster, and the row, the chip, the label, and the section all render nothing — every session then shares the host composition, and there is nothing to choose between or manage. A deployment that configures no writable root answers `authorable: false`, and the section stays a read-only browser: the shipped compositions still open in the viewer, but every copy action is disabled with the reason as its tooltip rather than offering a dialog whose create always fails.

+
+These limits define the current preset surfaces. They are current package constraints, not a general composition comparison or a task backlog.
+
 - **A preset without metadata is listed by id** — display text is optional, and a copy given no name deliberately falls back to its directory name rather than presenting itself identically to its source.
 - **A revealed path is display text, not a link** — where the host has no desktop opener the row shows the directory to copy by hand; the browser cannot open a host filesystem location itself.
 - **Composition edits are invisible to the page** — the files are edited outside the browser and nothing on the wire announces a file change, so the roster re-reads on its own actions, `settings/changed`, and `connection/reset`, not on every disk edit.

+## 概述
 
-## 为什么它是"新建会话"的偏好设置
+本包提供 Web GUI 的 agent preset 表面：通用设置中的一行，选择新建会话据以组装的 preset；新建会话界面的一枚 chip，选择下一个会话的 preset；会话标题旁的一个只读标签；以及一个设置分区，用于管理名单——复制、删除、默认值，以及通往 preset 自身文件的入口。会话的 preset 在创建时即固定，因此选择作用于此后开启的会话，运行中的会话保持它们开始时的组装。当部署未组装任何 preset 时，四个表面都不渲染任何内容，每个会话共用宿主组装。
 
-会话的 preset 在创建时即固定——宿主拒绝以不同 preset 接管已存在的会话，因为该会话的历史是在最初那份 preset 的工具下产生的。因此本行不可能是实时切换，它也如实说明了这一点：更改只对此后开启的会话生效，而运行中的会话保持它们开始时的组装。

-chip 以部署默认值打开，其选择是**暂存**的——该界面先于它要应用到的会话存在。暂存值会在某个会话成为当前会话且仍为空白时抵达该会话；这既覆盖工作区连接新建的会话，也覆盖它复用的那个空白会话，而搭 `sessions.create` 的便车会漏掉后者。暂存值一经使用即被清空，因此下一个新会话重新以默认值打开——与它旁边的工作区选择器完全一致。

-第三个表层，位于会话标题旁：**本会话**所运行的 preset，作为静态装饰呈现。在那里放一个控件，等于承诺一次宿主会断然拒绝的切换。它从会话自身的摘要读取 preset，并在 General 行所读的同一份名单上解析显示名称。转发的 owner 事件 `agent-preset/selected` 会在每个标签页中把已经提交的空会话切换折进这份共享摘要；发起方标签页可能已经采用 RPC 回执，而合并是幂等的。
+设置分区把名单呈现为卡片：复制对话框是创建 preset 的唯一入口——浏览器不编辑任何组装文本——每张自定义卡片都保留一个打开 preset 自身文件的位置动作。默认值可在任一表面设置；删除会移除 preset 目录，而已据其组装的会话继续运行。随附 preset 在只读查看器中打开，不提供位置或删除。名单行携带 `broken` 时渲染为标记卡片，其主体与复制均被禁用，因为损坏 preset 的副本只是另一个损坏 preset；损坏的自定义行保留位置与删除动作，以便修复文件、清掉幽灵目录。
 
-## 它读什么、写什么
+### 对话式入口
 
-选项与当前默认值都来自同一次 `agentPreset.list` 调用。名单本身已经报告了"未显式选择的会话会得到哪个 id"，因此本行无需对 settings schema 做内省；写入目标是 `agent-presets` settings 命名空间的 `default` 字段，也正是宿主在创建时解析的那个字段。
+名单携带自指的 `cordis` preset 时，一张虚线添加卡会暂存它并开启新会话——分区关闭设置面板，新建会话 chip 自己的应用器负责组装工作区流程产出的空白会话。
 
-本地创作的 preset 的权限恰好等于它所引用的插件，因此列表会标注 `user` 行，而不是把每个 preset 都呈现为随附且已审核的。
+-----
 
-preset 文件提供一套未国际化的 `name` 与 `description`，Web 将其用于所有 `user` 行和未知的 `system` 行。对于四个随附 id（`standard`、`code`、`minimal` 与 `cordis`），只有名单将该行标记为 `system` 时，Web 才会从当前 locale 解析这两个字段；同名的 `user` preset 仍使用其文件元数据。
+<a id="understand-the-implementation"></a>
+## 理解实现
 
-本行在自身命名空间的 `settings/changed` 以及 `connection/reset` 时重新读取：名单是一个活动目录，默认值是一项设置，外部编辑与重新连接都可能改变它。

-## 管理分区
+选项与当前默认值都来自同一次 `agentPreset.list` 调用——名单本身已报告未显式选择的会话会得到哪个 id，因此该行无需对 settings schema 做内省——写入目标是 `agent-presets` settings 命名空间的 `default` 字段，也正是宿主在创建时解析的字段。新建会话 chip 与标题标签共用一个控制器，因为暂存选择属于流程而非任何单个会话；暂存值在会话到达时应用（既覆盖工作区连接新建的会话，也覆盖它复用的空白会话），被拒绝时丢弃。[`dsh-client-connection`](../connection/README.zh.md) 使用同一浏览器会话认证 `agentPreset.read`、`copy`、`openDocument`、`remove`、`list` 及其他所有 Host API 方法。组装仍会指明一个会话所运行的插件，因此读取属于侦察，而 copy、remove 与 openDocument 管理名单并驱动宿主桌面。分区在自身操作、`settings/changed` 与 `connection/reset` 时重读，因为组装文件在浏览器之外编辑，线上没有任何机制宣布文件变动。
 
-第四个表层，独立的设置页（`settings.section`，id 为 `agent-presets`，排在「模型」之后——选模型是日常操作，而组装 agent 是它背后那件塑造部署形态的事）：名单以卡片呈现，复制对话框是创建 preset 的唯一入口，随附组装则在只读查看器中展示。
+</details>
 
-浏览器不编辑任何组装文本。在网页文本域里编 YAML 是弱功能（无补全、无高亮、无 diff），因此新 preset 是宿主端对既有 preset 的一次复制——对话框只收集一个 id（它将成为目录名，所以必须当场取好、事后无法更改）与一个可选显示名，跨越传输层的只有 `{ from, id, name? }`。其余一切——描述、组装、skills——都在 preset 自己的文件里编辑，而本页的另一职责正是把用户送到那些文件面前：复制以打开新目录作为收尾，每张自定义卡片也保有一个位置操作。宿主没有桌面打开器时（名单上的 `hasDocument: false`；远程与容器部署），同样的操作改为把目录以文本显示在卡片上，而不是提供一个点了没反应的按钮。
+-----
 
-preset 自行发布描述，长度不限，而网格让每一行卡片等高——因此不加约束的描述会决定整份名单的高度。卡片把描述截断为四行，其余内容由 tooltip 承载，且仅在文本确实被裁切时才挂载。截断由 CSS 完成，因此无论卡片显示多少，完整描述始终留在无障碍树中。
+<a id="further-exploration"></a>
+## 进一步探索
 
-随附 preset 在只读查看器中打开。它是副本据以出发的已知良好组装，因此能读到它正是意义所在；它不提供位置也不提供删除——它的安装目录会被升级覆盖，不归用户管理。开篇引导语告诉用户：复制一份既有预设改成自己的，或用「创造模式」让 Agent 帮你创建。
+当 preset 面不够用时阅读以下页面。它们从浏览器表面进入 preset 领域与组装模型。
 
-复制旁边是对话式入口：名单携带自指的 `cordis` preset 时，一张虚线添加卡（模型页的同款样式）会暂存它并开启新会话——分区经外壳的 owner-prop `close` 关闭设置面板，新会话 chip 自己的应用器负责组装工作区流程产出的空白会话。seat 会防止晚到的名单加载回退显示：暂存选择优先，其次是当前会话已携带的组装，最后才是部署默认值。
+- [dsh-agent-presets](../../preset/agent-presets/README.zh.md)——这些表面读取并管理的宿主名单与组装。
+- [ui-conversation](../ui-conversation/README.zh.md)——声明 chip 与标签填充的首屏与会话头部槽位。
+- [ui-settings](../ui-settings/README.zh.md)——承载通用行与名单分区的设置外壳。
+- [客户端包映射](../README.zh.md)——相邻的浏览器 UI 包。
 
-对话框复刻宿主自身的约束规则（`[a-z0-9][a-z0-9-]*`），并拒绝已被占用的名称——复制从不覆写。这两项检查只是便利：宿主会重新校验，失败时对话框报告的正是宿主的答复。
-
-删除会移除整个 preset 目录。已据其组装的会话继续运行——组装在会话创建时挂载一次，此后没有任何东西会重新读取该文件。
-
-名单行携带 `broken`（宿主的形状检查发现组装缺失或不可加载）时渲染为标记卡片：红色边框、「加载失败」徽记（discovery 观察到的事实，而非断言文件已损坏——常见起因是用户刚编辑或删除了组装文件）、原样展示的原因、卡片主体禁用——它不能成为默认——复制也禁用，因为损坏 preset 的副本只是又一个损坏的 preset。损坏的自定义行保留位置与删除动作：文件正是修复它的地方，而删除正是清掉幽灵目录（组装文件被手动删除、目录仍占着 id）的方式；损坏的内置行连查看器也不提供——没有可读的组装可展示。两个选择器（通用设置行与新会话 chip）则完全不列出损坏的 preset：它们选的是下一个会话的组装，列出无法组装的选项只会把失败推迟到会话启动。
-
-设置默认值写入的是 `agent-presets` settings 命名空间，宿主需将其暴露给配置客户端（[`dsh-apiproxy`](../../host/apiproxy/README.zh.md) 维护一份显式白名单——不在其中的命名空间会让选择器动一下然后悄悄忘记）。
-
-[`dsh-client-connection`](../connection/README.zh.md) 用同一浏览器会话认证 `agentPreset.read`、`copy`、`openDocument`、`remove`、`list` 及其他所有 Host API 方法。组装仍指明一个会话所运行的插件，因此读取它是侦察，而 copy/remove/openDocument 管理名单并驱动宿主桌面。
-
-## 何时不显示这些表层
-
-未组装任何 preset 的部署返回空名单，本行、chip、标签与分区都不渲染任何内容——此时每个会话共用宿主组装，也就无从选择或管理。未配置可写根目录的部署返回 `authorable: false`，分区随之退化为只读浏览：随附组装仍可在查看器中打开，但每个复制操作都被禁用并以原因作提示，而不是给出一个创建必然失败的对话框。

 # @deepseek-ai/dsh-client-ui-attachment

-Dynamic attachment presentation plugin for the conversation UI. It waits for the `conversation.input.attachments`, `conversation.message.images`, and `conversation.trajectory.images` declarations through `ctx.slots.inject`, then registers the composer draft-image rail, document drop target, the history image gallery serving both the Chat transcript and the Trajectory inspector, and the original-image lightbox. The conversation slot owner supplies attachment data, image loading, callbacks, and its namespace translator; presentation components remain pure props and are not exported from the package entry.
+## Summary
 
-## Attachment rail
+This package renders everything the conversation UI shows about attachments: pending draft images under the composer, a full-viewport drop invitation, durable images in Chat and Trajectory, and a lightbox for the original image. It is a pure presentation layer — attachment data, image loading, and callbacks come from the conversation package through declared slots. Choose it for the DeepSeek Chat-style image experience; non-image files have no surface here.
 
-`AttachmentRail` renders pending draft images as fixed 64px thumbnails (16px radius) in one horizontally scrolling row whose scrollbar stays hidden. Overflow is announced by circular edge arrows instead: each pages one viewport (minus one card of context, floored at 200px) with smooth scrolling (instant under `prefers-reduced-motion: reduce`), and arrow visibility is recomputed from scroll geometry on scroll, item-count changes, and rail size changes (a ResizeObserver on the rail element, so sidebar and panel resizes count, not only window resizes). The rail scrolls horizontally only: a non-passive listener consumes every wheel tick with a vertical component — nothing scrolls the conversation behind the composer — converting a pure vertical wheel to a horizontal step (LINE/PAGE deltas normalized to pixels, per-tick travel clamped to 60px) and keeping a diagonal pan's horizontal intent, while purely horizontal pans stay native. A newly added item is revealed at the rail's end; removal keeps the scroll position, and a rail that mounts over an already-populated draft keeps its start position. Each thumbnail opens its original through `onOpen` on a single click, and its remove control sits inside the card's top-right corner, hidden until the card is hovered or the control keyboard-focused; coarse-pointer (touch) surfaces show it permanently because they have no hover. The owner decides mounting and renders the rail only while items exist.

-`MessageImage` renders one durable history image, loading a session-authorized URL through the owner's `ImageLoader`; a failed load renders an explicit retry control, and a settled load answers a single click by opening `ImageLightbox` (clicks during loading are ignored). Sizing follows DeepSeek Chat: a message's lone image (`variant="single"`) renders at 240px on its longer edge with the displayed aspect ratio clamped to [0.25, 4] — the overflow is cropped by `object-fit: cover`, anchored to the top of very tall images and the left of very wide ones — and never upscales past its natural size; an image among several (`variant="tile"`) is a fixed 64px square. `ImageGallery` wraps a message's images in one aligned wrapping flex group (`end` for user messages, `start` for assistant messages), picks the variant from the image count, and renders nothing for an empty list. `ImageLightbox` is a document-level modal preview over the shared dialog mask (`--dsw-alias-bg-mask-1` + `--dsw-mask-blur`, painted on its own layer so the blur never touches the previewed image) that closes on Escape, a mask press, or its close control, and restores focus to its opener on unmount.

-## Drop overlay
+<a id="use-this-package"></a>
+## Use this package
 
-`DropOverlay` is the full-viewport invitation shown while a file drag is over the page: illustration, title, and a limits line while drops are accepted (`disabled` swaps the blocked illustration and hides the limits line). The layer is pointer-inert — the owner's document-level drag listeners keep the enter/leave count and decide accept/reject; the overlay only shows state. It portals to the body like the lightbox.
+Mount this plugin alongside [`ui-conversation`](../ui-conversation/README.md); it waits for the conversation package's slot declarations and registers its surfaces into them. Users then see the draft-image rail with per-image remove and click-to-open, the drop overlay with its limits line, message images sized by count, and the Escape/mask/close lightbox.
 
+### Draft images
+
+A draft image shows as a fixed 64px thumbnail in one horizontally scrolling row; edge arrows page the rail when overflow hides items, and the scrollbar stays hidden. A newly added item is revealed at the rail's end, removal keeps the scroll position, and a single click opens the original through the owner's `onOpen`.
+
+### Message images and the lightbox
+
+A message's lone image renders at 240px on its longer edge (aspect clamped to [0.25, 4], never upscaled); images among several render as fixed 64px squares. A loaded image opens the document-level lightbox on click; a failed load shows a retry control instead. The lightbox closes on Escape, a mask press, or its close control, and restores focus to its opener.
+
+### Drop overlay
+
+While a file drag is over the page, the full-viewport overlay announces the drop: illustration, title, and a limits line when drops are accepted. The overlay only shows state — the owner's document-level listeners decide accept or reject.

-对话 UI 的动态附件呈现插件。它通过 `ctx.slots.inject` 等待 `conversation.input.attachments`、`conversation.message.images` 与 `conversation.trajectory.images` 声明，随后注册输入框草稿图片栏、文档拖放目标、同时服务 Chat 会话记录与 Trajectory 检查器的历史图片画廊，以及原图灯箱。conversation slot 持有方提供附件数据、图片加载、回调及其命名空间翻译器；呈现组件保持纯 props，且不从包入口导出。
+## 概述
 
-## 附件栏
+本包渲染对话 UI 中与附件相关的一切：composer 下的待发送草稿图片、全视口拖放邀请层、Chat 与 Trajectory 中的持久图片，以及查看原图的灯箱。它是纯呈现层——附件数据、图片加载与回调都经声明槽位来自 conversation 包。需要 DeepSeek Chat 风格的图片体验时选择它；非图片文件在此没有任何表面。
 
-`AttachmentRail` 将待发送草稿图片渲染为固定 64px（16px 圆角）的缩略图横排，滚动条始终隐藏，溢出改由两端的圆形箭头提示：每次翻页滚动一个视口宽度（减去一张卡片作为上下文，下限 200px）并平滑滚动（`prefers-reduced-motion: reduce` 下瞬时完成），箭头的显隐在滚动、条目数量变化和栏自身尺寸变化时依据滚动几何重算（rail 元素上的 ResizeObserver，因此侧栏、面板的宽度变化也计入，不只是窗口尺寸变化）。附件栏只允许横向滚动：非 passive 监听器消费所有带纵向分量的滚轮事件——不会滚动输入框背后的会话记录——纯纵向滚轮转为横向步进（LINE/PAGE 单位先归一化为像素，单次行程钳制在 60px 内），对角平移保留其横向分量，纯横向平移保持原生滚动。新增条目会滚动到栏尾展示，删除则保持原位，带着已有草稿重新挂载的栏保持起始位置。每张缩略图单击经 `onOpen` 打开原图，删除按钮位于卡片内部右上角，悬停卡片或键盘聚焦时才显示；粗指针（触屏）设备没有悬停，因此常显。是否挂载由持有方决定，仅在有条目时渲染。

+## Summary
 
-The three occupants install as one declaration-aware registration set through nested `slots.inject()` calls. The package therefore works whether its row activates before or after the sidebar and conversation declarers, withdraws all occupants when either declaration collapses, and leaves no partial brand mix during HMR. It retains no runtime state. The node half is an empty Loader seat, and the browser title remains a build-environment concern outside this package.
+This package fills the browser brand slots — `sidebar.brand.mark`, `sidebar.brand.name`, and `conversation.hero.brand.mark` — with the official DeepSeek Harness mark and name. It registers these occupants only when the client bundle builds with the `official` profile; every other build loads the plugin but registers nothing, so the shell fallbacks stay visible. Choose it when the deployed identity is DeepSeek's own; a deployment with its own brand composes a different package into the same slots instead. It retains no runtime state and contributes nothing to model requests.

+## Use this package
+
+Mount this plugin in the browser roster of a deployment whose identity is DeepSeek's own, then build the client with the `official` profile so the occupants register.
+
+### Choosing the profile
+
+`DSH_CLIENT_BUILD_PROFILE` selects which brand renders. An `official` build shows the official mark and name in the sidebar and the mark in the conversation hero; any other value leaves the shell fallbacks — the fish mark and the local-build label — in place. The plugin still loads and validates in both cases; only the registration is profile-gated.
+
+### Replacing the brand
+
+A deployment with its own identity leaves this package out and composes another package that occupies the same three slots. Occupying a slot is the only composition route; there is no brand configuration surface here.

+## Summary
+
 The browser Chat target for Conversation assembly. It registers Chat event definitions and snapshot construction, supplies `useChat`, renders transcript nodes and details, and owns Chat-specific stores, actions, localization, and scroll restoration; historical image URLs resolve through the Conversation-owned per-session cache (`ctx.uiConversation.imageUrl`). Its Assistant and Turn Tail definitions fold packed historical Assistant runs without expanding their members.

 ## System prompt row
 
-Chat contributes a `System prompt` row for a non-empty initial or resumed request, an explicit series start, or an actual system-field change; same-series config-only or tool-only changes, tool steps, and retries do not duplicate it. Chat places the first header in a step at that request's message boundary — turn start for step one, step start thereafter — before the user-role messages sent with the request, matching the provider envelope's system-before-messages order; when the preceding header is outside a partial window, a non-initial header stays at its own Event and renders conservatively until prepend supplies that predecessor. The row stays collapsed by default and mounts the complete prompt in the same 141px code-block body as an opaque context injection — model-facing text with its real line breaks, not Markdown — only while expanded; it has no streaming path. Systemless headers produce no row.
+Chat shows a collapsed `System prompt` row for each non-empty initial or resumed request, explicit message-series start, or real system-field change. It does not repeat the row for same-series config-only or tool-only changes, tool steps, or retries. The row appears before that request's user messages, matching the provider envelope, and expands to the exact model-visible text with its original line breaks. A partial history window renders a non-initial header conservatively until the preceding page arrives; a header without a system prompt creates no row.

 English | [中文](README.zh.md)
 
-Client command API (`ctx.commandUi`): the session-keyed command-directory cache, the `/` command source with `matchSpace`/`matchEnter` decision hooks, three-kind dispatch (`execute` / `popupSelect` / `leadingInput`), and popupSelect registration for business packages. The [web command Agent Note](../../../.agents/notes/implemented/architecture/2026-07-25-web-command-surfaces-and-assembly.md) records the decision.
+## Summary
 
-`src/client/contract.ts` is the fixed business contract: `CommandUiContract.register(name, spec)` and `decorate(name, spec)` are everything a business package consumes; `CommandUiSpec{options, onSelect}` keeps popup data self-contained — the shell component belongs to this package and business packages never see it. A contribution is a client-owned command (a host-name collision fails loud); a decoration adds a bare-invocation popup to an EXISTING host command. The host keeps its catalog row, argument claim (space / argued Enter), and lifecycle logging, and a decorated name with no host row in the session's directory never fires. Command kinds derive per dispatch, never per registration: a host descriptor with `input` is `leadingInput`, a registered `CommandUiSpec` is `popupSelect`, and everything else is `execute`.
+Typing a `/` command in the composer opens the matching surface — a registered popup, a host command's input, or a direct execution — and a command line is never silently downgraded to a plain prompt. Business packages contribute command surfaces through `ctx.commandUi`, registering a popupSelect spec (`/model`, `/permission`) or decorating an existing host command with a picker while the host keeps its catalog row and argument claim. Space and Enter resolve the line against the session's directory: a host descriptor with `input` is `leadingInput`, a registered `CommandUiSpec` is `popupSelect`, and everything else is `execute`.
 
-`CommandDirectory` (`src/client/directory.ts`) is the one wire-derived cache, keyed by session. Ordinary sessions fetch through `command.list({sessionId})`, and the source's scope-birth `warm` hook prewarms the session's entry. Catalog-addressed continuable children resolve an empty command directory locally: `command.list` is Agent-bound, so prewarming it would activate a child merely to view persisted history. Entries are soft-invalidated by the forwarded `commands/change` owner event (old snapshots serve while the repull flies) and by forwarded `agent-preset/selected` for that one session (recomposing an agent registers nothing, so the registry-wide signal never fires for it), hard-invalidated by `connection/reset`, and epoch-guarded so a superseded pull can never overwrite a newer one. `matchSpace` answers synchronously from this cache only; `matchEnter` strong-waits it on the SubmitAttempt signal and rejects on warmup failure — a `/` line is never silently downgraded to a plain prompt.
+## Table of Contents
 
-`matchEnter` also enforces the submission envelope: when the composer submits with image attachments, only a host command declaring `input.images` proceeds (its claim carries `images: true` and its submit forwards the serialized payloads to `command.execute`); every other command route — contribution popup, decorated popup, non-declaring claim, bare detached execute — throws the localized `notice.imagesUnsupported` refusal, which the input machine publishes as one error notice and the composer renders as a transient Toast banner with the draft and images retained. An image-carrying submit whose host handler answers an error result maps to an error outcome so the composer keeps the images; imageless submits keep the plain success mapping because the durable flow node owns the outcome rendering.

-After `command.execute` returns a matched command result, this browser emits local `command/executed(sessionId, name, result)`. Other clients receive the durable command nodes through the Host event stream but never this acknowledgment, so a browser-only side effect can select successful results from the client that submitted the command without treating Session replay as an action request. Listener failures are logged and contained one by one; they cannot change the already-admitted command result or prevent later listeners from running.
+-----
 
-Menu queries fuzzy-match ordered, case-insensitive subsequences of command names. Prefixes rank first; separator boundaries, adjacent characters, and shorter gaps rank the remaining matches, with directory and contribution order breaking ties. This affects discovery only: space and Enter still require an exact command name. Rationale: [Web slash-command fuzzy discovery](../../../.agents/notes/implemented/feature/2026-08-04-web-slash-command-fuzzy-discovery.md).
+<a id="use-this-package"></a>
+## Use this package
 
-`PopupSelectController` (`src/client/popup.ts`) is the headless shell state: `PopupSelectView` self-registers into `conversation.input.overlay` (the SlotMap key is ui-conversation's; this package pulls the declaration in with a type-only import — no runtime edge). The shell is a transient layer holding focus while open; token-segment consumption after onSelect runs both branches through `consumeTokenSegment` (menu-path span CAS, enter-path bare-token equality) against the draft face the wiring layer binds via `bindDraft`.
+Mount this plugin alongside `ui-input-trigger` and `ui-conversation`; the `/` source then appears in the trigger menu, and business packages register their command surfaces through `ctx.commandUi`. Typing `/model` opens the registered popup; a host command with an argument claim opens its input or executes directly.
 
-The `/client` entrypoint exports the plugin body (`apply`/`inject`), `CommandUiRuntime`, the directory and popup classes with their state types, and the fixed contract types; the shell component itself is internal to the overlay registration.
+### Kinds and decorations
 
+A contribution is a client-owned command — a host-name collision fails loud. A decoration adds a bare-invocation popup to an EXISTING host command: the host command keeps its catalog row, its argument claim, and its lifecycle logging, and a decorated name with no host row in the session's directory never fires. Menu queries fuzzy-match ordered, case-insensitive subsequences of command names; prefixes rank first.
+
+### Image-carrying submissions
+
+When the composer submits with image attachments, only a host command declaring `input.images` proceeds; every other command route throws the localized `imagesUnsupported` refusal, which renders as a transient toast while the draft and images stay in place — a command can never consume the text and strand the images.

 ## Model Experience
 
-Indirectly, through the host `command.execute` RPC this package's dispatch and `claim.submit` paths trigger: a matched command's handler mutates host domain state that other packages project into the next request (the `/plan` handler flips plan mode, whose owning package injects its `plan:policy` system-prompt section), while the command line itself, the detached result, and every menu/notice rendering stay client-side and never enter the session log.

 #### KV Cache effect
 
-None directly; this package neither assembles nor sends a provider request. Command handlers it triggers may change what the owning host packages contribute to the next request's system prompt (a section appearing or disappearing replaces earlier request tokens and invalidates the provider prefix from that point), but that effect is owned and documented by each command's host package.

-客户端命令 API（`ctx.commandUi`）：以会话为 key 的命令目录缓存、带 `matchSpace`／`matchEnter` 决策钩子的 `/` 命令 source、三类派发（`execute`／`popupSelect`／`leadingInput`），以及面向业务包的 popupSelect 注册。[Web 命令 Agent Note](../../../.agents/notes/implemented/architecture/2026-07-25-web-command-surfaces-and-assembly.zh.md) 记录了这项决策。
+## 概述
 
-`src/client/contract.ts` 是固定的业务 API 约定：`CommandUiContract.register(name, spec)` 与 `decorate(name, spec)` 是业务包消费的全部内容；`CommandUiSpec{options, onSelect}` 自己提供 popup 数据——外层组件归本包所有，业务包永远见不到它。贡献项是客户端自有命令（与 host 命令同名时会明确报错）；装饰项则为**已存在的** host 命令添加裸调用 popup。host 保留目录行、带参 claim（空格／带参数的 Enter）与生命周期记账，被装饰的名字若在会话目录中无 host 行，则永不触发。命令类型按每次派发派生，绝不在注册时定型：带 `input` 的 host descriptor 是 `leadingInput`，注册了 `CommandUiSpec` 的是 `popupSelect`，其余全部是 `execute`。
+在 composer 中键入 `/` 命令会打开匹配的表面——已注册的弹窗、宿主命令的输入或直接执行——命令行绝不会被静默降级为普通提示词。业务包经 `ctx.commandUi` 贡献命令表面：注册 popupSelect 贡献项（`/model`、`/permission`），或用选择器装饰既有宿主命令，宿主保留其目录行与参数声明。空格与回车对照会话目录解析命令行：带 `input` 的宿主描述符是 `leadingInput`，注册了 `CommandUiSpec` 的是 `popupSelect`，其余全部是 `execute`。
 
-`CommandDirectory`（`src/client/directory.ts`）是唯一的 wire 派生缓存，以会话为 key。普通会话通过 `command.list({sessionId})` 拉取，source 的 scope 出生 `warm` 钩子会预热该会话的缓存项。由目录寻址的可继续子代理会在客户端解析为空命令目录：`command.list` 绑定 Agent，若预热它，就会仅因查看持久化历史而激活子代理。缓存项由转发的 owner 事件 `commands/change` 软失效（重拉在途期间旧快照继续服务），也由转发的 `agent-preset/selected` 对该会话单独软失效（重组 agent 不产生任何注册，注册表级信号不会为它触发），由 `connection/reset` 硬失效，并以 epoch 把关，被取代的旧拉取永远无法覆盖更新的结果。`matchSpace` 只凭该缓存同步应答；`matchEnter` 在 SubmitAttempt 信号上强等缓存，预热失败即拒绝——`/` 开头的一行绝不会被静默降级为普通提示词。
+## 目录
 
-`matchEnter` 还强制执行提交信封：composer 携带图片附件提交时，只有声明了 `input.images` 的宿主命令继续（其 claim 携带 `images: true`，其 submit 把序列化载荷转交 `command.execute`）；其余每条命令路径——contribution 弹窗、decoration 弹窗、未声明的 claim、bare 分离执行——都会抛出本地化的 `notice.imagesUnsupported` 拒绝，输入状态机发布一条错误通知，composer 以瞬态 Toast 横幅呈现它，草稿与图片原样保留。带图提交若宿主处理器返回错误结果，则映射为错误 outcome，composer 保留图片；不带图的提交维持原有的一律成功映射，因为结果呈现由持久化 flow 节点负责。

-`command.execute` 返回已匹配的命令结果后，当前浏览器会发布本地 `command/executed(sessionId, name, result)`。其他客户端只会通过 Host 事件流收到持久命令节点，不会收到这条确认，因此浏览器专属副作用可以筛选由实际提交命令的客户端收到的成功结果，而不会把 Session 回放当成操作请求。监听器失败会逐项记录并隔离，不会改变已经准入的命令结果，也不会阻止后续监听器运行。
+-----
 
-菜单查询会按顺序且不区分大小写地模糊匹配命令名的子序列。前缀排名最高；其余匹配项按分隔符边界优先、相邻字符优先、间隔越短越优先的规则排序，若仍同分，则以目录顺序和贡献项顺序打破平局。此行为只影响命令发现：space 和 Enter 仍要求命令名精确匹配。原理：[Web 斜杠命令模糊发现](../../../.agents/notes/implemented/feature/2026-08-04-web-slash-command-fuzzy-discovery.zh.md)。
+<a id="use-this-package"></a>
+## 使用本包
 
-`PopupSelectController`（`src/client/popup.ts`）是不含界面的外壳状态：`PopupSelectView` 自行注册进 `conversation.input.overlay`（SlotMap key 归 ui-conversation 所有；本包只以 type-only 导入引入该声明——没有运行时依赖边）。壳是打开期间持有焦点的瞬态层；onSelect 之后的 token 片段消费在两条分支上都经 `consumeTokenSegment` 执行（菜单路径做 span CAS，回车路径做裸 token 相等比较），作用于接线层经 `bindDraft` 绑定的草稿表层。
+与 `ui-input-trigger` 及 `ui-conversation` 一起挂载本插件；`/` source 随即出现在触发菜单中，业务包经 `ctx.commandUi` 注册自己的命令表面。键入 `/model` 打开已注册的弹窗；带参数声明的宿主命令打开其输入或直接执行。
 
-`/client` 入口导出插件主体（`apply`／`inject`）、`CommandUiRuntime`、目录类和 popup 类及其状态类型，以及固定的约定类型；外层组件本身是 overlay 注册的内部实现。
+### 种类与装饰
 
+贡献项是客户端自有命令——与宿主命令同名会明确报错。装饰为**已存在的**宿主命令添加裸调用弹窗：宿主命令保留其目录行、参数声明与生命周期记账，被装饰的名字在会话目录中无宿主行时永不触发。菜单查询按顺序且不区分大小写地模糊匹配命令名的子序列；前缀排名最高。
+
+### 带图提交
+
+composer 携带图片附件提交时，只有声明了 `input.images` 的宿主命令继续；其余每条命令路径都会抛出本地化的 `imagesUnsupported` 拒绝，以瞬态 toast 呈现，草稿与图片保持原位——命令绝不消费文本却抛下图片。

+## Summary
+
 `ui-conversation` owns target-neutral Conversation assembly and the shared browser shell. It consumes Session Controller `SessionEventLikeEntry` feeds, exposes React-free registries and per-Session bindings through `ctx.uiConversation`, and contributes the `useConversation`, `useInput`, and `inputActions` standard props through `ctx.uiSession`. It also owns the per-session durable image URL cache: `ctx.uiConversation.imageUrl(sessionId, attachment)` resolves one session-authorized browser URL per attachment and revokes it with the Session binding, so every Conversation target shares one `session.attachment` read. Concrete targets such as Chat are separate packages that register their own Definitions, snapshot builders, Views, and renderers.

+## 概述
+
 `ui-conversation` 拥有与 target 无关的 Conversation 组装和共享浏览器 shell。它消费 Session Controller 的 `SessionEventLikeEntry` feed，通过 `ctx.uiConversation` 暴露不依赖 React 的 registry 与逐 Session binding，并通过 `ctx.uiSession` 提供 `useConversation`、`useInput` 和 `inputActions` 标准 props。它还拥有按会话的持久化图片 URL 缓存：`ctx.uiConversation.imageUrl(sessionId, attachment)` 为每个附件解析一个经会话授权的浏览器 URL，并随 Session binding 释放而撤销，因此所有 Conversation target 共享一次 `session.attachment` 读取。Chat 等具体 target 位于独立 package，由各自 package 注册 Definition、snapshot builder、View 和 renderer。

 # @deepseek-ai/dsh-client-ui-deliverables

-Produced-files and clickable-reference feature owner. The Node half registers final-response guidance with the system-prompt registry; the browser half registers the deliverables row a finished turn ends with into the chat view's `conversation.chat.turnTail` hole and links matching inline-code references in the closing prose. The shipped Web patch is the only composition that loads this package. Removing its one cordis.yml entry removes the guidance, row, and prose links together.
+## Summary
 
-`deliverablesDefinition` folds each Turn's successful first-party mutation calls into engine-published `DeliverablesTurnData`; `producedForClosing` reads that data with the closing Assistant seq. The source is the validated raw arguments of `write`, `edit`, and the mutating `str_replace_editor` commands (`create`, `str_replace`, and `insert`), never presentation data or closing prose: a produced file is listed whether or not the model remembered to name it. Reads, deletes, unsupported tools, malformed calls, and failed results contribute nothing; a path appears once per Turn in first-seen order. A new mutation tool needs an explicit Client contribution before it joins this list. The Conversation Location index owns Turn membership, so a Turn that mutates and then ends without content text cannot spill into the next Turn's row.
+This package renders the deliverables row a finished turn ends with — the files the mutation tools created or modified — and links matching inline-code references in the closing prose, so a mentioned file opens in the Host. The vocabulary comes from the mutation tools' own `locations`, never from the closing prose — a produced file is listed whether or not the model remembered to name it. The shipped Web patch is the only composition that loads this package; removing its cordis.yml entry removes the guidance, row, and prose links together.
 
-`ProducedFiles` renders the row between the closing message's body and its IconActions footer: a quiet label and one measured file lane. It shows the largest leading prefix that fits (up to six chips; basename text, full path as the `title`) while reserving the exact localized `+ N files` width, so the remainder stays visible without wrapping or horizontal scrolling. Each chip opens through the owner-supplied `openFile` — the same Host opener the tool rows use, with the chat view resolving relative paths against the session cwd. When files are hidden, a second-line **Show in folder** action opens the session workspace through that same owner path only while the page is loopback and the current Host handshake reports `canOpenPath`; direct remote Web and headless/container Linux Hosts omit the action by default. Design rationale: the [workspace file links Agent Note](../../../.agents/notes/implemented/feature/2026-07-31-web-workspace-file-links.md).
+## Table of Contents
 
-The closing prose carries the same vocabulary. This plugin provides the `chatFileMentions` service the chat view consults per closing message: `producedFileMentions` resolves an inline-code token by exact path, or by being exactly the basename of exactly one produced path — a basename two paths share stays inert rather than guessing, so a mention link can never open the wrong file or 404. A resolved mention keeps its code chip and takes the markdown sheet's link language — link-blue at rest, underlined on hover, exactly like URL-promoted inline code — with the full path as its `title`; mentions never render inside anchors or streaming text. Decision record: the [inline file mentions Agent Note](../../../.agents/notes/implemented/feature/2026-08-07-web-inline-file-mentions.md).

-The Node half registers the static `ui:deliverable-file-references` system-prompt section. It asks the model to mention the primary files it successfully created or modified and to write those and any other changed-file references as Markdown inline code, using the exact file-tool path or a basename only when unique within the Turn. The guidance makes the renderer's accepted syntax explicit; it does not govern unrelated path discussions or widen the renderer's successful-mutation vocabulary.

+## Use this package
+
+Mount this plugin alongside `ui-conversation`; a finished turn then ends with the produced-files row between the closing message's body and its action footer. Each chip opens the file through the Host opener, with relative paths resolved against the session cwd; a **Show in folder** action opens the session workspace when the page is loopback and the Host reports it can open paths.

-- **Mention matching is exact path or unique basename only.** A suffix mention (`out/index.html` written as `index.html` resolves; `deep/out/index.html` written as `out/index.html` does not) stays inert; widening the matcher is deferred until a real closing-message shape needs it.
-- **Files created indirectly by terminal commands remain outside the matching vocabulary.** Naming such a file in inline code does not make it clickable unless a successful mutation location also records that path.
-- **Native folder handoff targets the Host desktop.** A browser reached through a non-loopback authority omits the action, as does a deployment reporting no native opener. SSH forwarding that makes a remote Host look loopback-local must set the gateway's `nativeOpen: false`; so must a headless macOS/Windows Host, a WSL deployment without working Windows interop, or any Linux desktop whose display/opener probe is a false positive.

-产出文件与可点击文件引用功能的属主。Node 侧向系统提示词 registry 注册最终回复指引；浏览器侧把已完成轮次末尾的产出文件行注册到 chat 视图的 `conversation.chat.turnTail` slot，并将收尾正文中匹配的行内代码引用转换为链接。正式提供的组合中只有 Web patch 加载本包；从 cordis.yml 中删去这一项会同时移除提示词、文件行与正文链接。
+## 概述
 
-`deliverablesDefinition` 把每个轮次中成功的第一方修改调用折叠进引擎发布的 `DeliverablesTurnData`；`producedForClosing` 结合收尾 Assistant 的 seq 读取这份数据。依据的是 `write`、`edit` 和 `str_replace_editor` 修改命令（`create`、`str_replace`、`insert`）经过校验的原始参数，而不是展示数据或收尾正文：无论模型是否记得点名，产出文件都会被列出。读取、删除、不受支持的工具、格式错误的调用和失败结果不贡献任何条目；同一路径在一个轮次内按首见顺序只出现一次。新的修改工具必须先增加显式 Client contribution，才能加入该列表。Conversation Location 索引负责维护轮次归属关系，因此一个轮次即使先修改文件、随后没有正文内容就结束，也不会溢进下一个轮次的行里。
+本包渲染已完成轮次末尾的产出文件行——列出修改工具创建或修改的文件——并把收尾正文中匹配的行内代码引用转为链接，让被点名的文件在宿主中打开。词表来自修改工具自身的 `locations`，而非收尾正文——无论模型是否记得点名，产出文件都会被列出。正式提供的组合中只有 Web patch 加载本包；删除其 cordis.yml 条目会同时移除指引、文件行与正文链接。
 
-`ProducedFiles` 在收尾消息正文与其 IconActions 之间渲染该行：一个低调的标签和一条经过测量的单行文件 lane。它展示能够放下的最大前缀（至多六个标签项；文本为文件名，完整路径作为 `title`），并为本地化后的精确 `+ N 个文件` 宽度预留空间，因此剩余计数始终可见，既不换行也不横向滚动。每个标签项经由属主提供的 `openFile` 打开——与工具行相同的 Host 打开器，chat 视图会把相对路径按会话 cwd 解析。存在隐藏文件时，第二行的**在文件夹中显示**也经由同一属主路径打开会话 workspace；它只在页面使用 loopback 且当前 Host 握手报告 `canOpenPath` 时出现，直接远程 Web 与 headless／容器 Linux Host 默认均省略该操作。设计原理：[workspace 文件链接 Agent Note](../../../.agents/notes/implemented/feature/2026-07-31-web-workspace-file-links.zh.md)。
+## 目录

-In-app directory browsing surface: the browser half of the browse picking interaction. It fills ui-workspace's two directory-flow holes (`conversation.hero.workspace.directoryFlow` and `sidebar.workspaces.directoryFlow`) with the Select Workspace Directory dialog, driving the local Host's `host.listDirectory` and `host.createDirectory` primitives through `ctx.workspaces`. Its node counterpart is [`dsh-host-directory-picker-browse`](../../host/directory-picker-browse/README.md); mounting this package composes the surface with that backend from one cordis.yml row, so no client code branches on a capability kind. Unlike the [`-native`](../ui-directory-picker-native/README.md) surface, the dialog needs no local operating-system chooser, so it also serves in-process and remote-browser deployments.

-The dialog is a 680×500 Miller-column view (clamped on short or narrow viewports): a header carrying the title, the selection-path breadcrumb, and a click-to-edit path zone, then one full-width level until a row is selected, after which the row splits evenly into level and children columns. Navigations land selection-anchored and quiet — the previous view keeps rendering while a crumb jump or a submitted path is scanned, and target and parent legs land as one frame — so stepping back keeps two panes away from the display root and no intermediate frame flashes. **New folder** opens a nested create dialog targeting the selected folder and selects what it creates; **Open** adopts the selected folder, falling back to the listed level. Host-flagged hidden entries stay hidden until the footer toggle reveals them, which is a client-side filter only.
+This package provides the in-app directory-browsing surface for the Web GUI: a Select Workspace Directory dialog that lists, navigates, and creates folders through the local Host, with no operating-system chooser involved. It fills the two directory-flow slots declared by `ui-workspace`, composing the client side of the browse picking interaction in one cordis.yml row. Choose it when the browser is remote or in-process and no local OS chooser exists; local deployments may prefer the [`-native`](../ui-directory-picker-native/README.md) surface.
 
-Confirming a directory is the picked path and dismissing the dialog is the cancellation. Browse failures — an unreadable target, a create conflict — stay inside the dialog's own alert surfaces, so this occupant never drives the owner's `onError` arm; the owner keeps the workspace-creation error surface. Both registrations install through nested `slots.inject()` calls because either declaring entry may activate later or replace its declaration, and the dialog's copy is registered in this package's own locale namespace: the two dictionaries land as a unit, so a failed activation cannot squat one locale of the namespace.
+## Table of Contents
 
-The node half is an empty `apply`: it exists so the plugin appears in the host cordis.yml and Loader, while the browser half ships through `exports["./client"]` and is discovered through the `dsh.client` manifest declaration.

 [English](README.md) | 中文
 
-应用内目录浏览界面：浏览式选取交互的浏览器半边。它通过 ui-workspace 的两个 directory-flow 洞（`conversation.hero.workspace.directoryFlow` 与 `sidebar.workspaces.directoryFlow`）装入「选择工作区目录」对话框，经 `ctx.workspaces` 驱动本地 Host 的 `host.listDirectory` 与 `host.createDirectory` 原语。它的 node 对侧是 [`dsh-host-directory-picker-browse`](../../host/directory-picker-browse/README.zh.md)；挂载本包即用一行 cordis.yml 把界面与该后端组合起来，因此没有任何客户端代码按能力种类分支。与 [`-native`](../ui-directory-picker-native/README.zh.md) 界面不同，本对话框不需要本地操作系统选择框，因此也服务于进程内与远程浏览器部署。
+## 概述
 
-对话框是 680×500 的 Miller 分栏视图（在较矮或较窄的视口中限制尺寸）：头部承载标题、选中路径面包屑和可点击编辑的路径区；下方在未选中行时是一整栏层级，选中后该行均分为「层级 | 选中文件夹的子项」两栏。导航落地是选择锚定且安静的——面包屑跳转或提交路径被扫描期间仍渲染旧视图，目标目录与父目录两段导航在同一帧完成——因此回退时，只要尚未到达显示根目录，就会始终保持两栏，且不会闪过中间帧。**新建文件夹**打开一个嵌套创建对话框，目标为选中的文件夹，并选中它创建出来的那个；**打开**采纳选中的文件夹，没有选中时回落到当前层级。Host 标记的隐藏条目默认不显示，直到页脚开关将其揭开——那只是客户端过滤。
+本包提供 Web GUI 的应用内目录浏览表面：一个「选择工作区目录」对话框，通过本地宿主列出、导航并创建文件夹，不涉及任何操作系统选择框。它填充 `ui-workspace` 声明的两个目录流程槽位，用一行 cordis.yml 组合出浏览拾取交互的客户端一侧。当浏览器为远程或进程内、没有本地操作系统选择器时选择它；本地部署可优先选择 [`-native`](../ui-directory-picker-native/README.zh.md) 表面。
 
-确认一个目录即为选中的路径，关闭对话框即为取消。浏览类失败——不可读的目标、创建冲突——都留在对话框自己的提示区内，因此本占位者从不驱动 owner 的 `onError` 分支；工作区创建的错误界面仍由 owner 持有。两处注册通过嵌套的 `slots.inject()` 安装，因为任一声明方条目都可能稍后激活或替换其声明；对话框文案注册在本包自己的 locale 命名空间下，两份字典作为一个单元落地，因此激活失败不会占住该命名空间的其中一种语言。
+## 目录
 
-node 半边是一个空 `apply`：它的存在只为让插件出现在 host 的 cordis.yml 与 Loader 中，浏览器半边经 `exports["./client"]` 出货，并通过 `dsh.client` 清单声明被发现。

 # @deepseek-ai/dsh-client-ui-directory-picker-native
 
 English | [中文](README.zh.md)
 
-Native directory-picker surface: the browser half of the native picking interaction. It fills ui-workspace's two directory-flow holes (`conversation.hero.workspace.directoryFlow` and `sidebar.workspaces.directoryFlow`) with a renderless occupant that answers each `open` request by driving the local Host's OS chooser through `ctx.workspaces.pickDirectory()`, then reports exactly one outcome — a picked path, a cancellation, or a failure — back through the owner conversation. The OS dialog itself belongs to [`dsh-host-directory-picker-native`](../../host/directory-picker-native/README.md); mounting this package composes the surface with that backend from one cordis.yml row, so no client code branches on a capability kind.
+## Summary
 
-Both registrations install as one transactional effect through nested `slots.inject()` calls, because either declaring entry may activate later or replace its declaration. The occupant arms once per rising `open` edge, so re-renders — including an adoption that keeps `open` true while `busy` — never launch a second chooser, and the owner withdrawing `open` re-arms the next request. Settlements ride a ref so the answer reaches the owner's latest handlers rather than the ones captured when the chooser opened. An unmount (HMR replacing the occupant) discards the settlement wholesale: the wire carries no per-request abort, so the host-side chooser survives until answered, its answer lands nowhere, and the replacement instance re-arms under the owner's still-open request.
+This package provides the native directory-picking surface for the Web GUI: when a workspace flow asks for a directory, a renderless browser occupant opens the operating system's own chooser on the machine running the Host and reports the single outcome — a picked path, a cancellation, or a failure. It fills the two directory-flow slots declared by `ui-workspace`, composing the client side of the native picking interaction in one cordis.yml row. Choose it when the browser runs on the same machine as the Host; in-process and remote-browser deployments need the [`-browse`](../ui-directory-picker-browse/README.md) surface instead.
 
-The node half is an empty `apply`: it exists so the plugin appears in the host cordis.yml and Loader, while the browser half ships through `exports["./client"]` and is discovered through the `dsh.client` manifest declaration.

+
+Choose this surface when the browser runs on the same machine as the Host, so an OS dialog can open there.

 English | [中文](README.zh.md)
 
-Goal surface plugin, browser half: the `GoalBar` strip is the second standalone card in the `conversation.input.dock` composer-context stack (order 10, after Todo and before Queue). The live goal arrives through `useProjection('goal')` — the host-computed whole value seeded by the history tail page and updated by `session/projection` frames — so the plugin owns no domain store, refresh chain, or event listener. The slot inject face carries only the four mutation verbs (edit / pause / resume / clear through `ctx.remote.goals` — an active goal offers the pause action, a paused one resume); each reads the CAS ref from the session's current projected value at call time and surfaces the rejected Remote error inline. The strip single-flights mutations synchronously because React's pending render cannot fence same-frame clicks; after a successful clear it immediately suppresses that exact goal id while the authoritative null projection catches up. Goal creation is outside this plugin; the shipped Web presets other than `minimal` mount `/goal` in their agent scope. Loading, absent, completed, and successfully cleared goals render nothing.
+## Summary
 
-The plugin separately projects each durable `/goal` `command/run` through its own Conversation Definition. It builds a `command-input` Chat Node before the generic command result Node and registers that Node's keyed renderer as a right-aligned 14px/22px monospace user-style bubble with the localized group name `Command input` / `命令输入` and no timestamp, copy, or branch actions. The visible non-command Node activates fresh Chat; reload reconstructs it from the run, while a history window containing only `command/done` keeps only the generic result row. This projection never creates `user/message` or a model turn.
+This package renders the goal surface in the Web GUI: a strip in the composer-context stack that shows the current goal of the session and offers edit, pause, resume, and clear actions. It reads the live goal from the host-computed projection and routes every mutation through the goal service, surfacing rejections inline. It also projects each durable `/goal` command run as a `Command input` bubble in the chat, so a goal command entered by the user or the model appears in the transcript. Goal creation is outside this plugin. The shipped Web presets other than `minimal` mount `/goal` in their agent scope.
 
-The `/client` exports are the plugin body (`apply`/`inject`), the `GoalBar`/`GoalDock` components, and the injected verb face types.

+## Use this package
+
+Mount this plugin alongside `ui-conversation` and the goal domain package; the strip then appears as the second card in the composer-context stack (after Todo, before Queue) whenever the session has a goal. An active goal offers pause; a paused one offers resume; edit rewrites the objective; clear removes the goal and suppresses the strip until the projection catches up.

 ## Model Experience
 
-Indirectly, through the `goals/edit`, `goals/pause`, `goals/resume`, and `goals/clear` Remote methods the strip invokes: each accepted mutation commits in a durable `agent/inbox/spliced` insertion, which the goal projection folds immediately, and queues a `goal/change` context message. The model sees that context only if a later pre-step admits it; discarding the queued message does not roll back the projected state. The strip itself adds no prompt content.

-Goal 界面插件（浏览器端部分）：`GoalBar` 条带是 `conversation.input.dock` composer 上下文堆栈中的第二张独立卡片（order 10，位于 Todo 之后、Queue 之前）。活值经 `useProjection('goal')` 到达——host 计算的全量值由历史尾页播种、由 `session/projection` 帧更新——因此本插件不持有领域 store、不设刷新链、不挂事件监听。slot 注入面只携带四个变更动词（edit / pause / resume / clear，经 `ctx.remote.goals` 调用——active 的 goal 提供暂停动作，paused 的提供恢复）；每个动词在调用时从会话当前投影值读取 CAS ref，并将 Remote 调用的拒绝错误内联呈现。由于 React 的 pending 渲染无法拦住同一帧内的点击，横条会同步为变更建立 single-flight 防护；清除成功后，会立即抑制该 goal id 对应的目标显示，直到权威的 null 投影追上。goal 创建不属于本插件；随附 Web preset 中除 `minimal` 外均在各自 agent scope 内挂载 `/goal`。加载中、无 goal、已完成和已成功清除的 goal 一律不渲染。
+## 概述
 
-该插件还会通过自有 Conversation Definition 投影每条持久 `/goal` `command/run`。它在通用命令结果 Node 之前构建一个 `command-input` Chat Node，并为该 Node 注册 keyed renderer；renderer 将其呈现为右对齐、使用 14px/22px 等宽字体的用户样式气泡，使用本地化分组名称 `Command input`／`命令输入`，且不含时间戳、复制或分支操作。可见的非命令 Node 会激活新 Chat；重新加载时会根据 run 重建该 Node，而仅包含 `command/done` 的历史窗口只保留通用结果行。该投影绝不会创建 `user/message` 或模型轮次。
+本包在 Web GUI 中渲染 goal 表面：composer 上下文堆栈里的一条条带，显示会话的当前目标，并提供编辑、暂停、恢复与清除动作。它从宿主计算的投影读取活目标，把每次变更都经 goal 服务路由，并把拒绝内联呈现。它还把每条持久的 `/goal` 命令运行投影为聊天中的 `Command input` 气泡，让用户或模型输入的 goal 命令出现在文本记录中。goal 创建不归本插件。除 `minimal` 外，随附的 Web preset 都会在其 agent scope 中挂载 `/goal`。

 # @deepseek-ai/dsh-client-ui-input-trigger
 
 English | [中文](README.zh.md)
 
-Input trigger pipeline plugin: `/` and `@` detection under the caret (word-boundary + guard-tier rules), the grouped candidate menu, and pick routing to registered sources. `ctx.inputTriggers` owns the source roster and resolves one `InputTriggerController` per session scope (`sessionOf`); the conversation wiring layer drives `track`/`arbitrate`/`onSpace`/`adjudicate` on the controller. The same controller exposes `toggleSource` for a chrome launcher to open exactly one registered source over a synthetic selection span; the resulting candidates still use the ordinary menu, keyboard arbitration, pick callback, and scoped input mutations. Sources receive a `ClientSessionContext` projection per call — sessions are always agent-backed, so the projection is the session identity alone. A source is warmed in every session controller it can reach: the roster present at scope birth warms during controller construction, and a source registered later is warmed into every live controller by the registration itself. Sources whose `lexicon` roll changes after warm implement `subscribeLexicon(session, listener)`; the controller re-polls on each notification and publishes the aggregation through its `lexicon` snapshot store. The pipeline is command-agnostic: space/enter adjudication polls the optional `matchSpace`/`matchEnter` hooks in registration order and the first non-undefined answer wins. Enter adjudication also carries a `SubmitEnvelope` (the composer's image-attachment count) so a source can refuse a submission it cannot consume whole; a `CommandClaim` declares `images: true` when its command accepts composer images, and its `submit` then receives the serialized payloads as a third argument.
+## Summary
 
-Layering: `src/core/` is the pure core — `detectTrigger`, `menuReduce`/`seedGroups`/`MENU_CLOSED`, `exactMatch`, zero React/DOM/cordis; `src/client/service.ts` is the shell wiring the core to the menu snapshot store, the per-hit candidate fetch (generation-gated, `AbortSignal`-superseded, failed sources drop silently with a console record), and the three pick paths. `ReferenceInsert.appearance` optionally identifies a `session`, `file`, or `folder` display without changing its serialized `ref`; the consuming composer owns the glyph and color. `src/types.ts` and the two `contract.ts` files are the frozen cross-package contract; changes require main-thread arbitration.
+This package powers the input trigger pipeline of the Web GUI: it detects `/` and `@` typed under the caret, shows a grouped candidate menu, and routes a pick to the registered source. Sources register through `ctx.inputTriggers` — the `/` command source (ui-commands), the `@` file and session reference sources (ui-reference), and any business package — and the conversation wiring drives the pipeline per session. Typing a trigger seeds every source registered for it; a chrome launcher can also open exactly one source over the current selection. The pipeline is presentation-only: picks produce command claims or reference inserts whose consequences belong to the consuming host and input packages.
 
-MenuView renders the menu store into the `conversation.input.overlay` slot (list kind, session scope) and renders null while closed. Typed triggers seed every source registered for that trigger; a programmatic launcher seeds only its requested source and publishes the source name through the controller's `launcher` snapshot store until the menu closes or typed tracking resumes. Groups sort by the optional `InputTriggerSource.order` (lower first, default 0, ties keep registration order) under title rows localized through the `inputTriggers.menu` locale namespace (an unknown source shows its raw name). `showGroupTitle: false` suppresses that row through pending and ready states, while a ready group whose candidates declare sections uses those section rows in place of the source title. The list height clamps to the space above the composer, and a pointer down outside both the menu and the surrounding composer card dismisses it. The slot is owned by ui-conversation's composer entry (anchor, children declaration, lifecycle); its SlotMap type merge lives in this package's `src/client/slots.ts` because the dependency direction (ui-conversation → ui-input-trigger) admits no reverse type import. Combobox pattern: focus stays in the textarea, rows pick on mousedown, the highlight rides `aria-activedescendant`.
+## Table of Contents
 
-The `/client` exports are the plugin body (`apply`/`inject`), `InputTriggerService`, `MenuViewInjected`, and the contract types. MenuView itself is internal — the slot registration closes over it.

-输入触发流水线插件：光标处的 `/` 与 `@` 检测（词边界 + guard tier 规则）、分组候选菜单，以及把 pick 路由到已注册 source。`ctx.inputTriggers` 拥有 source roster，并按会话 scope（`sessionOf`）各解析一个 `InputTriggerController`；对话接线层在 controller 上驱动 `track`／`arbitrate`／`onSpace`／`adjudicate`。同一个 controller 还暴露 `toggleSource`，供 chrome launcher 在一段合成 selection span 上只打开一个已注册 source；所得候选仍走通常的菜单、键盘仲裁、pick callback 与 scoped 输入改写。source 每次调用收到一个 `ClientSessionContext` 投影——会话始终由 agent（智能体）支撑，因此投影只含会话身份。source 在它能触达的每个会话 controller 中都会被预热：scope 创建时 roster 中已有的 source 会在 controller 构造期间预热，晚于此注册的 source 由注册动作本身预热进每个仍存续的 controller。`lexicon` 名录在预热后仍会变化的 source 实现 `subscribeLexicon(session, listener)`；controller 每收到通知就重拉，并把聚合结果经其 `lexicon` 快照 store 发布。流水线与命令无关：空格／回车裁决按注册序轮询可选的 `matchSpace`／`matchEnter` 钩子，第一个非 undefined 的应答胜出。回车裁决还携带 `SubmitEnvelope`（composer 的图片附件数量），使 source 能拒绝它无法整体消费的提交；命令接受 composer 图片时，`CommandClaim` 声明 `images: true`，其 `submit` 随之以第三个参数收到序列化后的图片载荷。
+## 概述
 
-分层：`src/core/` 是纯内核——`detectTrigger`、`menuReduce`／`seedGroups`／`MENU_CLOSED`、`exactMatch`，零 React／DOM／cordis；`src/client/service.ts` 是壳层，把内核接到菜单快照 store、逐 hit 候选拉取（以 generation 把关、后继请求经 `AbortSignal` 取代旧请求、失败的 source 静默丢弃并留一条 console 记录）和三条 pick 路径上。`ReferenceInsert.appearance` 可以把显示类型标为 `session`、`file` 或 `folder`，且不会改变其序列化 `ref`；图标与颜色由消费它的输入框负责。`src/types.ts` 与两个 `contract.ts` 文件是冻结的跨包约定；变更需经主线程仲裁。
+本包为 Web GUI 提供输入触发流水线：检测光标处键入的 `/` 与 `@`，显示分组候选菜单，并把 pick 路由到已注册 source。source 经 `ctx.inputTriggers` 注册——`/` 命令 source（ui-commands）、`@` 文件与会话引用 source（ui-reference），以及任何业务包——对话接线层按会话驱动这条流水线。键入触发器会 seed 为该触发器注册的所有 source；chrome launcher 也可以在当前选区上只打开一个 source。流水线仅做呈现：pick 产出命令声明或引用插入，其后果属于消费它们的宿主与输入包。
 
-MenuView 把菜单 store 渲染进 `conversation.input.overlay` slot（列表类，会话 scope），菜单关闭期间渲染 null。键入式 trigger 会 seed 为该 trigger 注册的所有 source；程序化 launcher 只 seed 所请求的 source，并在菜单关闭或重新开始键入式 tracking 前，通过 controller 的 `launcher` 快照 store 发布该 source 名称。分组按可选的 `InputTriggerSource.order` 排序（越小越靠前，默认 0，同值保持注册序），组标题行经 `inputTriggers.menu` locale 命名空间本地化（未知 source 显示其原名）。`showGroupTitle: false` 会在 pending 与 ready 状态全程隐藏该行，ready 且候选项声明了 section 的组则以这些 section 标题行取代 source 标题。列表高度受限于 composer 上方的可用空间，指针落在菜单与所在 composer 卡片之外即关闭菜单。该 slot 由 ui-conversation 的组合器条目拥有（锚点、children 声明、生命周期）；其 SlotMap 类型合并放在本包的 `src/client/slots.ts`，因为依赖方向（ui-conversation → ui-input-trigger）不允许反向的类型导入。combobox 模式：焦点始终留在 textarea，行在 mousedown 时完成 pick，高亮由 `aria-activedescendant` 承载。
+## 目录
 
-`/client` 导出接口是插件主体（`apply`／`inject`）、`InputTriggerService`、`MenuViewInjected` 与约定类型。MenuView 本身是内部实现——slot 注册以闭包持有它。

 # @deepseek-ai/dsh-client-ui-jobs
 
 English | [中文](README.zh.md)
 
-Web background-job feature owner: contributes one entry to `conversation.session.header.actions` listing the `ctx.jobs` records this session can see. The data arrives entirely through the `jobsBySession` list mirror that the [Session Controller](../../api/session-controller/README.md) folds from `session/jobs` frames, so this package issues no RPC and holds no state beyond popover visibility.
+## Summary
 
-The trigger renders only when the session has at least one job, so an ordinary conversation never grows a control for a capability it is not using. Its badge counts `running` plus `stopping` and is omitted at zero, leaving a session that holds only finished jobs a quiet entry point into its history rather than one advertising a count of nothing. The popover is a flat list: live rows first by `startedAt` ascending, then settled rows by `finishedAt` descending, with a same-millisecond tie broken on start order so the host's map iteration never decides it. A row shows the producer kind, the label, a status marker, the producer's `detail` in place of the generic status word once it has one, and an elapsed duration. That duration advances once per second while the row is live and freezes at `finishedAt`; the clock runs only while an open list holds something that moves. A settled row missing `finishedAt` reads as zero rather than as a negative figure, and a duration past an hour stays in hours rather than growing a day vocabulary no producer currently reaches.
+This package renders the background-job surface of the Web GUI: a session-header action that opens a popover listing the jobs this session can see. It reads host-computed registry state through the runtime's `jobsBySession` mirror and issues no RPC of its own. The trigger appears only when the session has at least one job, with a badge counting running and stopping jobs; settled rows stay visible and de-emphasized until the registry drops them. The model's own view of the same jobs belongs to `dsh-tool-jobs`; this package is a read-only projection for the human.
 
-Settled rows stay visible and de-emphasized until the registry drops them at owner disposal. They are in the snapshot, a failed job's `detail` is the only place its failure is legible, and filtering them out here is work the output and cancellation phases would undo. A running one-shot background subagent therefore appears both here and in the [subagent catalog](../ui-subagent/README.md): the catalog navigates into the child's transcript, while this list is the only handle a future cancellation can attach to.
+## Table of Contents
 
-Escape closes the list and returns focus to the trigger, as does a pointer press outside it. The last job disappearing closes the list before the control unmounts, so focus never vanishes from a removed node. Styling uses tokens only; copy goes through the package's own `job` locale namespace. The behavior is specified by the [Web background-job display Agent Note](../../../.agents/notes/implemented/feature/2026-08-08-web-background-job-display.md).

+## Use this package
+
+Mount this plugin alongside the runtime; the job action then appears in the session header whenever the session has at least one job. A click opens the popover: live rows first by start time, then settled rows by finish time, each showing the producer kind, label, status, and an elapsed duration that ticks once per second while live and freezes at completion.
+
+### Dismissal and limits
+
+Escape closes the list and returns focus to the trigger, as does a pointer press outside it. The list shows what one session can see through the wire view, so a job owned by another session never appears here; a process restart empties the list while the transcript keeps the `run_in_background` cards that started those jobs.

 - **Rows are read-only** — a job's streamed output and a human-initiated cancellation are separate phases.

 [English](README.md) | 中文
 
-Web 后台任务特性的归属方：向 `conversation.session.header.actions` 贡献一个条目，列出当前会话可见的 `ctx.jobs` 记录。数据完全来自 [Session Controller](../../api/session-controller/README.zh.md) 从 `session/jobs` 帧折叠出的 `jobsBySession` 列表镜像，因此本包不发任何 RPC，除弹层开合外不持有任何状态。
+## 概述
 
-只有当会话至少有一个任务时才渲染触发器，普通对话不会因为一项未被使用的能力而长出控件。角标计数为 `running` 加 `stopping`，为零时省略，这样只剩已完成任务的会话保留一个安静的历史入口，而不是宣告一个「零」。弹层是一个扁平列表：活跃行在前按 `startedAt` 升序，随后终态行按 `finishedAt` 降序；毫秒相同的并列按启动顺序打破，宿主的 map 迭代顺序永远不参与决定。一行显示生产者 kind、label、状态标记、生产者一旦给出 `detail` 就取代通用状态词的那段文字，以及已耗时。该耗时在活跃时每秒推进，并在 `finishedAt` 冻结；只有当打开的列表里确实有会动的东西时时钟才运行。缺少 `finishedAt` 的终态行读作零而不是负数，超过一小时的耗时停留在小时单位，不会长出任何生产者目前都到不了的「天」词汇。
+本包渲染 Web GUI 的后台任务表面：一个会话头部动作，打开后以弹层列出本会话可见的任务。它经运行时提供的 `jobsBySession` 镜像读取宿主计算的注册表状态，自身不发任何 RPC。触发器只在会话至少有一个任务时出现，角标计数运行中与停止中的任务；终态行保持可见并弱化，直到注册表把它们丢弃。模型对同一批任务的视角属于 `dsh-tool-jobs`；本包是给人类看的只读投影。
 
-终态行保持可见并弱化，直到注册表在 owner 销毁时把它们丢掉。它们本就在快照里，失败任务的 `detail` 是其失败唯一可读之处，在这里过滤掉它们是输出与中断两期要推翻的工作。因此一个运行中的一次性后台 subagent 会同时出现在这里和 [subagent 目录](../ui-subagent/README.zh.md)里：目录负责进入子会话的 transcript，而这个列表是将来中断能力唯一可能附着的句柄。
+## 目录
 
-Escape 关闭列表并把焦点交还触发器，在其外部按下指针同理。最后一个任务消失时先关闭列表再卸载控件，焦点因此不会从一个被移除的节点上凭空消失。样式只用 token；文案走本包自己的 `job` locale 命名空间。行为由 [Web 后台任务展示 Agent Note](../../../.agents/notes/implemented/feature/2026-08-08-web-background-job-display.zh.md) 规定。

 # @deepseek-ai/dsh-client-ui-layout
 
 English | [中文](README.zh.md)
 
-Shell plugin: three-column AppFrame (drag handles and concession chain) plus the `ctx.layout` panel-geometry service; it registers into the runtime-owned `root` slot and declares `sidebar`, `conversation`, `details`, and `conversation.empty`. The sidebar resize boundary is an invisible hit strip, while the details boundary retains its floating pill; only details shrinks during concession and then auto-closes. A closed sidebar retains a 56px control rail while details closes to zero width. The package also seats the theme presenter: it consumes resolved `ctx.theme` snapshots and projects them onto the document (`html { color-scheme }` for native UA chrome, `body[data-ds-dark-theme]` from the active color scheme, the theme's alias tokens as inline variables on body, the content font size as `--dsh-content-font-size` on body, and one owned `<meta name="theme-color">` whose content follows the computed body background). Measuring after palette and token application keeps the rendered background as the single color authority; disposing the presenter removes its metadata node with its other global writes.
+## Summary
 
-AppFrame always mounts the conversation and details columns; a connected Session renders through `SessionProvider`. It also projects the selected Session title over the build-configured product title or the localized `common.brand.localBuild` fallback, so locale revisions update document metadata with the rest of the root entry. The transient layout store starts the sidebar at its default width and details closed, and it never reads or writes `localStorage`. Hero and other unselected states also derive a zero rendered details width without changing that stored preference. AppFrame retains the last non-blank Session id across those states: the first Session remains closed, an explicit details action opens the contract default width, returning to the same Session restores its unchanged width, and selecting a different Session closes details before paint. The conversation owner share is empty, while the sidebar owner share contains only `collapsed` and `width`; registrants obtain business data from standard hooks and actions from their own inject faces.
+This package provides the shell layout of the Web GUI: a three-column AppFrame with resizable sidebar and details panels, a concession chain that shrinks the details column and then auto-closes it when space runs out, and the `ctx.layout` panel-geometry service other plugins call to open or close the details column. It also seats the theme presenter, which projects the resolved color scheme, alias tokens, content font size, and `theme-color` metadata onto the document. Choose it for the standard window chrome; panel geometry is transient and resets on reload.
 
-The `/client` exports are the plugin body (`apply`/`inject`), `LayoutController`, and the four owner-share interfaces. AppFrame, the panel store, and the concession solver remain package-internal.

+## Use this package
+
+Mount this plugin at the root slot; it then renders the app frame around whatever occupies the sidebar, conversation, and details columns. Users resize the sidebar by dragging its invisible hit strip and the details panel by dragging its floating pill; when the window narrows, only details shrinks, then auto-closes. A closed sidebar retains a 56px control rail; details closes to zero width.
+
+### Theme presentation
+
+The presenter consumes resolved theme snapshots and projects them onto the document: `html { color-scheme }` for native UA chrome, `body[data-ds-dark-theme]` from the active color scheme, the theme's alias tokens and `--dsh-content-font-size` as inline variables on body, and one owned `<meta name="theme-color">` whose content follows the computed body background. Disposing the presenter removes its metadata node with its other global writes.

+
+One `register()` call contributes `AppFrame` into the runtime's built-in `'root'` slot and, in the same breath, declares the four child slots (`sidebar`, `conversation`, `details`, `shell.overlay`), seats the layout store (panel geometry), and wires the `ctx.layout` panel-action service. The transient layout store starts the sidebar at its default width and details closed, and never reads or writes `localStorage`. AppFrame always mounts the conversation and details columns; a connected Session renders through `SessionProvider`. It projects the selected Session title over the build-configured product title or the localized `common.brand.localBuild` fallback, so locale revisions update document metadata with the root entry. The theme presenter is a second effect: pure DOM writes from resolved snapshots — initial state through the getter once, then event-driven only, with no React path. It applies palette, font-size, and token variables before measuring the rendered background as the single color authority.

+These limits define the current layout behavior. They are current package constraints, not a general window-manager comparison or a task backlog.

 - **Panel geometry is transient** — reload restores the sidebar default and details closed; switching between distinct Session ids also closes details and forgets its dragged width, while unselected surfaces render details at zero width without modifying geometry.
 - **Concession-chain auto-close derives a zero width without touching the preferred width** — the panel restores itself when the window widens; consumers must not read the stored details width as the rendered truth.
 - **No scroll anchoring during squeeze reflow** — layout changes may move the reader's viewport.

-外壳插件：三栏 AppFrame（拖动手柄与让步链）加 `ctx.layout` 面板几何服务；它注册到运行时拥有的 `root` slot，并声明 `sidebar`、`conversation`、`details` 和 `conversation.empty`。侧边栏的缩放边界是不可见命中条带，详情栏边界则保留其浮动胶囊；让步期间只有详情栏会收缩并随后自动关闭。关闭的侧边栏仍保留 56px 控制栏，详情栏则关闭到零宽度。该包还提供主题呈现器：它消费解析后的 `ctx.theme` 快照，并将其投影到 document（用 `html { color-scheme }` 驱动原生 UA 控件，依据当前配色方案设置 `body[data-ds-dark-theme]`，将主题的别名 token 设为 body 上的内联变量，把正文字号写为 body 上的 `--dsh-content-font-size`，同时拥有一个 `<meta name="theme-color">`，其内容随计算后的 body 背景色更新）。在应用调色板和 token 后进行测量，可确保渲染后的背景成为唯一的颜色依据；呈现器在 dispose（资源释放）时会移除其自有的元数据节点，并一并清除其写入的其他全局状态。
+## 概述
 
-AppFrame 始终挂载会话栏和详情栏；已连接 Session 通过 `SessionProvider` 渲染。它还会把选中 Session 的标题投影到 build 配置的产品标题或已本地化的 `common.brand.localBuild` 回退之上，因此 locale revision 会与 root entry 的其余内容一起更新文档元数据。布局 store 是瞬时状态，侧边栏以默认宽度启动，详情栏则保持关闭，且该 store 从不读写 `localStorage`。hero 和其他未选中状态也会将详情栏的渲染宽度派生为零，但不会改变存储的宽度偏好。AppFrame 会跨越这些状态保留最后一个非 blank 会话 id：首个会话保持关闭；显式打开详情栏的操作会使用约定默认宽度；返回同一会话时恢复其未改变的宽度；选择不同会话时，详情栏会在绘制前关闭。会话 owner share 为空，侧边栏 owner share 只包含 `collapsed` 和 `width`；注册方通过标准钩子获取业务数据，并从各自的 inject 接口获取操作。
+本包提供 Web GUI 的外壳布局：一个三栏 AppFrame，带可缩放的侧栏与详情面板；一条让步链，在空间不足时先收缩详情栏、随后自动关闭它；以及 `ctx.layout` 面板几何服务，供其他插件调用以打开或关闭详情栏。它还承载主题呈现器，把解析后的配色方案、别名 token、正文字号与 `theme-color` 元数据投影到 document。需要标准窗口外观时选择它；面板几何是瞬时的，重新加载即重置。
 
-`/client` 导出表层包含插件主体（`apply`／`inject`）、`LayoutController` 和四个 owner-share 接口。AppFrame、面板 store 与让步求解器仍属于包内部。

 English | [中文](README.zh.md)
 
-Per-message feedback plugin, browser half: a Like/Dislike pair plus an optional note, contributed as the `feedback` entry (order 10) of the `conversation.chat.assistant-actions` strip. The strip is declared by `ui-conversation` and rendered inside the finalized assistant message's IconActions row, between copy and branch, so the controls inherit that row's chrome and hover behavior. The note editor itself does not sit in that row: it is a `role="dialog"` popover portaled to `document.body` and anchored under its trigger, so the row keeps its single line whether the editor is open or closed and the panel is not clipped by the conversation column. A rating or list-load failure shows inline in the row; a note-save failure shows inside the popover, which stays open so the draft can be corrected. Only finalized messages reach the slot — an interruption-frozen partial carries no `messageId` and therefore no feedback controls. The strip renders once per turn, on the closing assistant message that owns the turn's IconActions row: earlier steps of a multi-step turn produce tool rows rather than a rateable body, so they present no controls even though the Host would accept them as targets.
+## Summary
 
-One `MessageFeedbackController` per Session backs every message control in that Session, so a single `messageFeedback.list` read seeds the whole transcript. The read is deferred to the first hover or focus rather than fired on mount, because the controls mount once per settled message in the visible history.
+This package adds per-message feedback to the Web GUI: a Like/Dislike pair plus an optional note, contributed as the `feedback` entry of the finalized assistant message's action strip. It renders on the closing assistant message of each turn — earlier steps of a multi-step turn produce tool rows rather than a rateable body. One controller per Session backs every message control in that Session, so a single list read seeds the whole transcript. Feedback is a sidecar: ratings and notes never enter the session log, the model context, or telemetry.
 
-Mutations go through `ctx.remote.messageFeedback`; the Host owns per-item compare-and-set. Every `put` and `delete` carries the `version` this controller last observed, and a `version-conflict` reply carries the authoritative item, so a lost race reconciles from the reply itself instead of refetching the Session. Mutations serialize per Session, so a queued operation always compares against the committed version. Re-clicking the recorded rating retracts the feedback; switching sides carries the existing note forward.

 English | [中文](README.zh.md)
 
-Model selection plugin, browser half: TWO entries over ONE per-session directory owned by `ModelDirectoryResolver` (`ctx.modelDirectories`). For ordinary sessions, the `/model` popupSelect contribution (registered through `ctx.commandUi`) and the composer's named `conversation.input.model` seat both load the session's advisory directory through `session.models` and submit through `session.selectModel` via the same `ModelDirectory` instance. The compact composer trigger opens a two-level Model/Effort menu: models stay provider-grouped, while the selected exact model supplies its adapter-owned effort names and default. The menu renders model and effort names only; catalog descriptions remain available to other consumers. `/model` applies the selected model's default effort, and the composer can then choose any advertised effort.
+## Summary
 
-The Host-reported provider/model/reasoning `ModelSelection` is the single selection fact, but it is echoed only when the exact provider/model pair remains in the advertised groups; an absent catalog row leaves the routable selection intact while the trigger prompts `Select model`, no stale row is synthesized, and no Effort row is shown until the user picks an advertised model. Directory loads and selections share a generation counter so an older response never overwrites a newer one; a connection reset drops every resident projection and repulls the Host-restored selection before display. Provider-local metadata failures list inline while usable groups stay selectable, and selection failures retain the prior selection and directory.
+This package provides model selection in the Web GUI: the `/model` popup command and the composer's model seat, both over one per-session directory of provider-grouped models. Choosing a model submits the complete selection — provider, model, and reasoning effort — which the Host snapshots at the next prompt-assembly boundary, so the following request uses it while a running step keeps its assembled selection. The composer seat shows a two-level Model/Effort menu: models stay provider-grouped, and the selected exact model supplies its adapter-owned effort names and default. When the Host reports that no adapter serves the session's route, the composer input goes inert until a route becomes available.
 
-When the Host reports that no adapter serves the session's route (`session.models.routable`), this plugin raises a composer block through `ctx.conversation.blocks` and the input goes inert with this plugin's own copy; recovering clears it without a reload. It follows `routable` and nothing else: a `null` — before the first load, or after one failed — never blocks, or a slow Host would lock a working composer, and catalog membership never blocks either, because a route serving a model it stopped advertising is missing from the groups yet perfectly usable. The trigger's own `Select model` fallback still covers that case, which is display, not a gate.
+## Table of Contents
 
-Directories are per-session, resolved lazily through `ctx.modelDirectories.directoryFor(sessionId)`, and disposed with the session scope. Addressed subagent sessions expose neither entry, and their directory rejects loads, selections, and reconnect refreshes, because ordinary Agent-bound model RPCs would activate persisted child history outside the direct-parent continuation path.

-Every resident directory refetches directly on forwarded `llm/adapters-updated` and `settings/document-updated` owner events. Provider topology, provider catalogs, and the default selection therefore converge without the Host or client runtime deriving a separate model-change alias.

-The `/client` exports are the plugin body (`apply`/`inject`), `ModelDirectoryResolver`, `ModelDirectory` with its state fields, and the seat's injected face type.
+<a id="use-this-package"></a>
+## Use this package
 
+Mount this plugin alongside `ui-conversation` and the commands package; the composer then shows the model seat next to the pending indicator, and `/model` opens the same directory as a popup. Both surfaces show the host-reported current selection when the exact provider/model pair remains in the advertised groups; a missing catalog row leaves the routable selection intact while the trigger prompts `Select model`.
+
+### Model and effort
+
+Models stay grouped by provider. The menu shows model and effort names only; catalog descriptions remain available to other consumers. The `/model` popup applies the selected model's default effort; the composer can then choose any advertised effort. An adapter without reasoning metadata leaves the Effort row absent; there is no arbitrary effort input.
+
+### Unroutable sessions
+
+When the Host reports that no adapter serves the session's route, this plugin raises a composer block and the input goes inert with its own copy; recovering clears it without a reload. A `null` before the first load or after one failed never blocks, and catalog membership never blocks either — a route serving a model it does not advertise is missing from the groups yet usable.

 [English](README.md) | 中文
 
-模型选择插件（浏览器侧）：**两个入口共用一份会话级目录**，由 `ModelDirectoryResolver`（`ctx.modelDirectories`）持有。对于普通会话，`/model` popupSelect 贡献项（经 `ctx.commandUi` 注册）与 composer 的具名 `conversation.input.model` slot 都通过同一个 `ModelDirectory` 实例，经 `session.models` 加载会话的建议目录，并经 `session.selectModel` 提交。紧凑型 composer 触发器会打开两级 Model/Effort 菜单：模型仍按提供方分组，所选具体模型则提供由其适配器持有的推理强度名称和默认值。菜单只呈现模型与推理强度名称；目录中的说明仍可供其他消费方使用。`/model` 应用所选模型的默认推理强度，composer 随后可以选择任一已公布的推理强度。
+## 概述
 
-Host 报告的 `ModelSelection` 是唯一的选择事实，其中包含提供方、模型与推理（reasoning）强度；但只有当该提供方／模型对仍在已公布分组中时才会回显。目录行缺席时，可路由的选择保持不变，但触发器会提示 `Select model`；系统不会合成陈旧行，且在用户选择已公布的模型之前不会显示 Effort 行。目录加载与选择共享一个代次计数器，旧响应不会覆盖新结果；连接重置会丢弃所有常驻目录投影，并在显示前重新拉取 Host 恢复的选择。各提供方的元数据获取失败会内联列出，同时可用分组仍可选择；选择失败会保留先前的选择和目录。
+本包提供 Web GUI 的模型选择：`/model` 弹窗命令与 composer 模型位，两者共用一份按提供方分组的会话级目录。选择模型会提交完整选择——提供方、模型与推理强度——宿主在下一次提示词组装边界对其快照，因此后续请求采用该选择，而运行中的步骤保留已组装选择。composer 位显示两级 Model/Effort 菜单：模型按提供方分组，所选具体模型提供其适配器持有的推理强度名称与默认值。当宿主报告没有适配器服务该会话的路由时，composer 输入停用，直到路由恢复可用。
 
-当宿主报告没有适配器服务该会话的路由（`session.models.routable`）时，本插件经 `ctx.conversation.blocks` 注册一个 composer 阻塞块，输入框随之停用并显示本插件自己的文案；恢复后无需重新加载即自动清除。它只跟随 `routable`：`null`（首次加载之前，或加载失败之后）绝不阻断，否则一个慢的宿主就会锁死一个本来可用的 composer；目录成员关系同样不阻断，因为一条仍在服务、只是不再公布该模型的路由不在分组里，却完全可用。触发器自己的 `Select model` 回退仍然覆盖那种情形——那是显示，不是闸门。
+## 目录
 
-目录按会话惰性解析（`ctx.modelDirectories.directoryFor(sessionId)`），随会话作用域一并 dispose（资源释放）。已寻址 subagent 会话不公开任一入口，其目录会拒绝加载、选择与重新连接刷新，因为绑定到 agent（智能体）的普通模型 RPC 会在直接 parent 继续执行路径之外激活持久化 child 历史。

-每一份常驻目录都会直接在转发的 owner 事件 `llm/adapters-updated` 与 `settings/document-updated` 上重拉。因此提供方拓扑、提供方目录与默认选择都能收敛，Host 与 client runtime 无需再派生一个单独的模型变更别名。

-Permission browser surfaces for two different lifetimes. The General-settings row reads the explicitly exposed `permission` Settings descriptor, derives its options from the host's dynamic `defaultPreset` enum, and writes one `settings.mutate` path operation with the descriptor revision. Its observable rides the slot system's `hooks` compartment, so the renderer owns React hook binding; a push invalidation refetches the descriptor. This value applies only when a later session is created; changing it does not switch the current session. Choosing Full access requires an explicit risk acknowledgement before the row writes it.
+## Summary
 
-The current-session surface remains a popupSelect DECORATION hung on the host `/permission` command (`ctx.commandUi.decorate`). A decoration is not a second command — the host command keeps its slash-menu row, the argued path (`/permission <preset>` switches directly), and the durable lifecycle logging; the decoration replaces only the bare invocation with the picker: one flat preset list with the current value marked active and kebab-case preset names rendered as title-case labels (`workspace-write` → `Workspace Write`, the composer chip's display transform twin), where a pick submits the `/permission <preset>` command line. Options and the active mark read the session's `permissions` projection (the same host-computed select the composer chip renders), so both current-session surfaces share one read source and one write path, and the pushed projection frame is the single confirmation both follow. The decoration is available exactly while the projection key is present; a permission-less composition shows neither picker nor Settings row.
+This package provides permission preset surfaces for two lifetimes in the Web GUI: a General-settings row chooses the default for later sessions without switching the current session. A picker on the host `/permission` command switches the current session through one flat preset list with the active value marked. Kebab-case names render as title-case labels, and `danger-full-access` is presented as `Full access`. Choosing full access requires an explicit risk acknowledgement before either surface writes it. Both surfaces read one host-computed projection and write through one path, so the pushed projection frame is the single confirmation both follow.

 # @deepseek-ai/dsh-client-ui-plan
 
 English | [中文](README.zh.md)
 
-Plan-mode status chip, a pure browser surface plugin. The browser half occupies the conversation-declared `conversation.input.plan` single seat (to the right of the access-mode control); the node half is an empty apply (the roster row). Plan behavior itself — the `/plan` command, the boundary-or-idle-committed `plan/mode` state, the `plan` projection unit, and the policy section — is owned by [`@deepseek-ai/dsh-plan-mode`](../../plan/plan-mode/README.md), composed independently on the host roster.
+## Summary
 
-Plan mode is entered through the `/plan` command path: users can choose Plan from the composer's `+` Command menu or type `/plan`, while this package renders no inactive plan control. While the host-computed `plan` projection's effective target is plan mode (`pending ? !active : active` — a folded host value, not client optimism, so an arriving frame corrects the chip either way), the seat renders the warn-colored "Plan ×" status button, which executes `/plan off` through `command.execute`; otherwise the seat stays empty — a host without plan-mode (or a Draft with no session) shows nothing. While plan mode is the effective target, the composer textarea's placeholder switches to the plan-task hint — "describe your task to generate plan", localized through ui-conversation's `conversation` locale namespace (the `placeholder.plan` / `hint.plan` keys) and shared verbatim with the claimed `/plan` command hint (rendered by the composer from the same projection; owner-supplied placeholders win).
+This package renders the plan-mode status chip in the Web GUI: when the host-computed projection's effective target is plan mode, the composer shows a warn-colored "Plan ×" button that turns plan mode off; otherwise the seat stays empty. Plan mode itself — the `/plan` command, the committed `plan/mode` state, the projection unit, and the policy section — belongs to `dsh-plan-mode`; this package only renders the projection and sends what a user could equally type. The model exits plan mode through the stable `exit_plan_mode` tool; its plan review uses the composed Web question channel.
 
-The chip carries the accessible description "Plan mode on, press to turn off". Admission failures (`matched: false`, business errors, transport faults) surface as an inline error and the chip stays until the projection confirms the exit.

+## Use this package
+
+Mount this plugin alongside `ui-conversation` and `dsh-plan-mode`; the chip then occupies the composer's plan seat to the right of the access-mode control whenever plan mode is active. Enter plan mode through the `/plan` command path — choose Plan from the composer's `+` Command menu or type `/plan` — and turn it off with the chip.
+
+### What the chip shows
+
+While the effective target is plan mode, the seat renders the warn-colored "Plan ×" status button, which executes `/plan off`. Otherwise the seat stays empty: a host without plan mode, or a Draft with no session, shows nothing. While plan mode is the effective target, the composer textarea's placeholder switches to the plan-task hint — "describe your task to generate plan" — unless the owning surface supplies its own placeholder.

+The chip occupies the conversation-declared `conversation.input.plan` single seat; the node half is an empty apply (the roster row). Reads ride the generic projection pair through the standard-kit `useProjection`: the effective target is `pending ? !active : active` — a folded host value, not client optimism, so an arriving frame corrects the chip either way. The seat's injected face carries one verb, `exitPlanMode`, which executes `/plan off` through `ctx.remote.commands.execute` and maps admission failures to an inline error line. The placeholder and hint text live in ui-conversation's `conversation` locale namespace and are shared verbatim with the claimed `/plan` command hint. The accessible description is "Plan mode on, press to turn off".

+These limits define the current plan chip. They are current package constraints, not a plan-mode comparison or a task backlog.

 - **Plan mode is guidance, not an execution sandbox** — deployments that require enforced read-only planning must compose the independent sandbox and approval policies.
 - **The chip belongs to the default composer** — a pending whole-composer interaction such as plan review temporarily replaces the InputBar and its chip.
 - **No inactive plan control** — entry uses the shared Command source; a session with the capability but inactive mode shows no plan affordance in the tool row.

-Pure React atoms (zero cordis): StateDot, DisclosureRow, ic_ds_* icons, Button/Pill/Menu/Modal/Input, the Toast transient banner, the OnboardingSurface first-run takeover (body-portaled mask + opaque stage that holds `#root` inert for exactly its own lifetime), the markdown family (MessageText/MarkdownText/JsonBlock), the read-only JsonTree inspector, the `useAnchoredMaxHeight` hook that clamps a bottom-anchored overlay to the viewport space above its anchor (re-measured on resize, scroll, and a caller-supplied dependency), the `useAnchoredPosition` hook that holds a fixed-position floating panel under its anchor (measure, offset, clamp inside the viewport margin, re-placed on capture-phase scroll, window resize, and the panel's own size changes), TerminalBlock, DiffBlock, ReadBlock, SearchBlock, and WebBlock.
+## Summary
 
-## Hover cards
+`dsh-client-ui-primitives` is the web client's shared React component library: every feature plugin composes its UI from these atoms, and nothing here depends on Cordis or the slot system. It provides the control set (buttons, pills, inputs, menus, modals, toast banners, disclosure rows, hover cards, connection banners), the icon glyphs and brand marks, positioning hooks for anchored overlays, and the content renderers for agent output: markdown with TeX math, terminal output, file reads, diffs, search results, web retrieval, and JSON inspection. The renderers are built for untrusted model output — raw HTML is dropped, links are neutralized or opened safely, and ANSI escape sequences are parsed rather than passed through. User-facing copy is supplied through label props; the feature plugin that composes an atom owns localization.
 
-`HoverCard` keeps its portaled preview reachable across the anchor gap with a pointer-leave grace. A consumer may also pass `copyText`: the card then exposes button semantics for pointer and keyboard activation, includes that value after the `copyLabel` prefix in its accessible name, writes the exact value through the package clipboard helper, and temporarily replaces its content with `copiedLabel` only after the host accepts the write. A non-collapsed text selection intersecting the card suppresses pointer-click activation, while success feedback retains the original card height and clears when the card closes or after one second. `copyLabel` and `copiedLabel` are label props because this zero-cordis atom cannot read the application locale; omitting `copyText` preserves the read/select-only card. Historical rationale: [the archived hover-card copy note](../../../.agents/notes/archived/feature/2026-07-31-hover-card-click-copy.md).

-`Toast` is the transient top banner: it slides in, holds at full opacity for three seconds, fades over one second, then calls `onDone` so the owner can unmount it. It renders `role="alert"` with an optional leading icon slot and takes its copy as a required prop (zero-cordis: the owner localizes). It body-portals with `pointer-events: none`, sits 120px from the viewport top, and centers horizontally over the optional `anchor` element (re-measured on window resizes) — the composer passes its card so the banner centers over the chat column rather than the whole window — falling back to the viewport center without one. Re-showing the same message requires a remount — owners key the element by a per-show sequence so an identical repeated message restarts the hold-and-fade cycle instead of silently reusing the faded banner. Under `prefers-reduced-motion: reduce` the slide-in is dropped and only the delayed fade remains. It layers above the ui-attachment image lightbox so a failure reported during a preview stays readable.
+-----
 
-## Markdown rendering
+<a id="use-this-package"></a>
+## Use this package
 
-`MarkdownText` renders GFM and `$…$`, `$$…$$`, `\(…\)`, and `\[…\]` TeX math from untrusted assistant output through React elements, with math typeset by KaTeX and trusted commands disabled; block-level same-line `$$…$$` is display math, including `\tag{}`. A narrow micromark extension lets asterisk strong emphasis ending in punctuation close before adjacent CJK text, where prose normally omits the whitespace CommonMark requires; single-asterisk emphasis, non-CJK adjacency, escapes, code, and math retain upstream parsing. It omits raw HTML, neutralizes relative and non-HTTP(S)/mailto links, opens HTTP(S) links with safe external-link attributes, and renders absolute HTTP(S) images without a referrer; relative paths, absolute local paths, `file:` URLs, and unsupported schemes retain their alt text. Inline code whose complete value is an absolute HTTP(S) URL keeps its code styling and gains the same safe external anchor; commands, partial URLs, other schemes, and fenced code remain inert. An optional `fileMentions` resolver lets the owning view link inline code that names a real file: the token keeps code styling and gains a button wired to the resolved opener, with the resolver's accessible label and full-path `title`. The renderer never guesses at what looks like a path — an unresolved token stays inert, mentions apply to settled renders only (the streaming cache must not bake in handlers that could go stale), and a token inside an anchor stays inert because a button cannot nest there. While a reply streams, `MarkdownText` parses incrementally: all but the trailing two blocks freeze as cached React elements and only the source tail behind them re-parses per chunk, so per-chunk work tracks the tail instead of the whole reply ([mechanism and DOM-parity contract](../../../.agents/notes/implemented/architecture/2026-08-06-web-markdown-incremental-ast-renderer.md)). Tables size by column count (deepsuite chat parity): under four columns — or inside a blockquote — a table fills its column and wraps cell text down to the cells' minimum readable width, while four-or-more-column tables keep their natural width, scroll horizontally inside their wrapper, and carry the stable `md-table-wide` class so a hosting layout can widen the wrapper past its column (the chat transcript's container-query breakout in `dsh-client-ui-conversation`); a wide table's horizontal bar reveals on hover or keyboard focus (the wrapper carries `tabindex="0"`) instead of staying painted ([decision record](../../../.agents/notes/implemented/feature/2026-08-19-web-markdown-wide-table-view.md)). `MessageText` remains the literal-text primitive for user-authored content. `extractMarkdownPlainText` removes Markdown presentation markup for compact labels while preserving raw HTML as literal text. Element spacing, responsive images, tables, links, and inline code use the same `--dsw-alias-markdown-*` / `--dsw-font-markdown-*` tokens as deepsuite `@deepseek/md`. Fenced blocks render through `CodeBlock` (language banner, copy control, shiki for the registered grammars); while a reply streams, a fence highlights incrementally as it grows — each chunk tokenizes newly completed text from the saved grammar state plus the still-growing last line, while completed lines keep their DOM — and the settled render swaps in shiki's HTML with an identical span tree ([decision record](../../../.agents/notes/implemented/feature/2026-08-20-web-streaming-fence-highlight.md)).
+Compose feature UI from these atoms whenever the web client needs a standard control or an agent-output renderer. They render through React only and take `--dsw-*` design tokens from the theme, so they fit any plugin without importing the theme or the slot system.
 
-## Terminal output
+### Controls and icons
 
-`TerminalBlock` renders a shell command as a terminal surface: one prompt row per line of the command (the shortened `cwd` label on the first row only, since the view knows one working directory and a `cd` moves later lines elsewhere, then that line), the command's output, a status pill for a non-zero exit code or a terminating signal, and a copy control that writes the raw `output` prop. A run-state `StateDot` marks the call once, on the first row, out of flow in a gutter the card reserves as its own left padding, so the dot sits inside the card box yet left of the prompt text. It reaches three of `StateDot`'s states — the chase while `running`, red for the same exit status that renders the pill, green otherwise — so a card states whether its command is still running rather than leaving that to be inferred from the presence of output; it carries one visually hidden text label because `StateDot` is `aria-hidden`. One dot regardless of line count is deliberate: the exit status is the whole call's, so a dot per line would claim a per-line outcome the view does not carry. Command text is `white-space: pre`, so repeated spaces, tabs, and an indented continuation render verbatim while the row stays single-line and ellipsizes. ANSI escape sequences are parsed with `anser` (bundled into this package's browser artifact) into React spans; cursor movements replay into a per-line column buffer before inert controls are stripped, since carriage return and backspace only MOVE the cursor: `100%` + CR + `OK` alone shows `OK0%`, while the `\x1b[K` a spinner writes with its redraw erases the tail so `100%\r\x1b[KOK` shows `OK`. Erase-in-line is honored in all three parameter forms, the cursor advances by terminal columns (8-column tab stops, two for emoji and CJK, none for a combining mark), and SGR state is normalized per cell as a terminal stores it, threading across lines and closing at the state the line ended in; basic-16 foreground colors map onto `--dsw-*` tokens, while 256-palette and truecolor values pass through as literal rgb. Output keeps `white-space: pre` with horizontal scrolling, so column-aligned output holds its alignment instead of soft-wrapping, and collapses to a head slice plus a tail slice past `maxLines` (default 16) behind an expand button. Rationale: [the web terminal card note](../../../.agents/notes/implemented/feature/2026-07-28-web-terminal-card.md).
+`Button`, `Pill`, `Input`, `Menu`, `Modal`, `Tooltip`, `DisclosureRow`, `StateDot`, `HoverCard`, `Toast`, `ConnectionBanner`, `RiskConfirmation`, and the `OnboardingSurface` first-run takeover cover the common interaction shapes. The `ic_ds_*` icon set and the `FishLogo`/`BrandWordmark` marks fill brand and inline-icon slots. `useAnchoredPosition` and `useAnchoredMaxHeight` keep floating panels and bottom-anchored overlays clamped to the viewport and following their anchor. `HoverCard` keeps its portaled preview reachable across the anchor gap and can expose a copy button through the `copyText` prop.
 
-## Read rendering
+### Rendering agent output
 
-`ReadBlock` renders a returned file window as a line-numbered, syntax-highlighted code surface: a bold path (or presenter-supplied title) banner with a copy control, then the content lines with their file line numbers in a gutter (a windowed read keeps the file's own numbering, so a read past an offset starts above 1). A `totalLines` exceeding the window count draws a `showing N of M` note, and the body collapses to a head slice plus a tail slice past `maxLines` (default 16, the TerminalBlock split arithmetic) behind an expand button. Highlighting runs through the same shiki path as `CodeBlock`. Rationale: [the web read card note](../../../.agents/notes/implemented/feature/2026-07-30-web-read-card.md).
+`MarkdownText` renders untrusted GFM and TeX math, blocks unsafe links and images, and can turn resolved file mentions into explicit controls. While a reply streams, it freezes completed blocks and highlights a growing fence from saved Shiki grammar state; the final render uses the same span tree ([incremental renderer](../../../.agents/notes/implemented/architecture/2026-08-06-web-markdown-incremental-ast-renderer.md), [streaming fence highlighting](../../../.agents/notes/implemented/feature/2026-08-20-web-streaming-fence-highlight.md)). `TerminalBlock`, `ReadBlock`, `DiffBlock`, `SearchBlock`, and `WebBlock` render the matching tool-result intent with copy controls, overflow handling, and ANSI processing where applicable. `JsonTree` and `JsonBlock` inspect JSON values read-only, while `MessageText` remains the literal-text primitive for user-authored content.
 
-## Diff rendering
+### Localizing copy
 
-`DiffBlock` renders a file mutation as an inline diff surface: one bold path header per file, the removed lines (`- `, error token) above the added lines (`+ `, success token), a `⋯` gap before a same-file second hunk, and a dim `└ +A -R · N file(s)` footer. Lines are `white-space: pre` with horizontal scrolling, so a source line holds its indentation instead of soft-wrapping, and the body collapses to a head slice plus a tail slice past `maxLines` (default 16, `TerminalBlock`'s split arithmetic) behind an expand button. A create (`oldText: null`) has no removed side. The copy control writes the prefixed diff text (path headers, `- `/`+ ` lines, the gap) so a multi-file copy stays attributable, and floats in the top-right corner rather than on a banner row of its own. Geometry mirrors `CodeBlock`/`TerminalBlock`. Rationale: [the web diff card note](../../../.agents/notes/implemented/feature/2026-07-30-web-diff-card.md).
+The atoms cannot read the application locale, so every piece of user-facing copy arrives through required label props. `HoverCard`, `TerminalBlock`, `JsonTree`, `CodeBlock`, `MarkdownText`, `JsonBlock`, `ConnectionBanner`, `Modal`, `DiffBlock`, `ReadBlock`, `SearchBlock`, and `WebBlock` accept complete localized labels. The package owns no language fallback; omission fails typechecking, and each feature maps its typed `t` seat into the primitive's label interface.
 
-## Search results
+-----
 
-`SearchBlock` renders a completed search, one component for both kinds (discriminated by `kind`). A `matches` (grep) shows each file as a bold path header with its `lineNumber: line` rows, the per-file group collapsible; a `paths` (glob) shows a flat path list. Both flatten to one row list the height cap slices head/tail over (default 16, the TerminalBlock split arithmetic), and neither soft-wraps — a long match line or path scrolls horizontally instead of folding. The banner summary folds the pre-cap total in when the tool capped the result (`显示 X / 共 N 处匹配 · K 个文件` for grep, `显示 X / 共 N 个路径` for glob), so the card never presents a capped result as complete; a copy control writes the whole structured result regardless of the cap or which groups are collapsed. Geometry mirrors CodeBlock/TerminalBlock. Rationale: [the web search card note](../../../.agents/notes/implemented/feature/2026-07-30-web-search-card.md).

+## Understand the implementation
 
-## Web retrieval
+<details>
+<summary>Implementation internals — click to expand</summary>
 
-`WebBlock` renders a completed web retrieval, one component for both kinds of the `web` render intent (discriminated by `kind`). A `search` shows an optional provider answer (through `MarkdownText`) above an ordered citation list: each source is a safe external link labelled by its title, or its hostname, falling back to the raw URL when the URL does not parse or has no hostname (a `file:`/`data:` URL) so a label is never blank; its snippet and publication date render below it. Only http(s) URLs become anchors (`target`/`rel` set) — the http(s) subset of the allowlist `MarkdownText` applies to untrusted links (it also permits `mailto:`, excluded here); any other URL renders as plain text. The whole list renders in one fixed-height scroll container (`max-height: 320px`, `overflow-y: auto`), so a list taller than that scrolls vertically in place instead of growing the card; `<li value>` pins each source's citation number, contiguous from 1, rather than leaving it to the `<ol>`'s implicit count. When a search legitimately returns no answer and no sources, the card shows an explicit empty-state note rather than a blank `<ol>` (the chat row does not surface the raw result content). A `fetch` shows a compact summary: the linked final URL and its HTTP status. Both mark a capped retrieval. Rationale: [the web result card note](../../../.agents/notes/implemented/feature/2026-07-30-web-result-card-frontend.md) and [the source scroll note](../../../.agents/notes/implemented/feature/2026-08-03-web-search-source-scroll.md).
+The package is one separation: presentational React atoms with zero Cordis and zero slot knowledge, styled only through `--dsw-*` tokens, while every feature-specific concern (locale, session data, composition) stays in the composing plugin.

+
+### Streaming markdown
+
+While a reply streams, `MarkdownText` parses incrementally: all but the trailing two blocks freeze as cached React elements and only the source tail re-parses per chunk, so per-chunk work tracks the tail instead of the whole reply. A growing fenced block tokenizes completed text from saved Shiki grammar state plus the unfinished last line; completed lines retain their DOM, and the settled render uses the same span tree. The settled full parse at finalize also resolves references that crossed the freeze boundary ([incremental renderer](../../../.agents/notes/implemented/architecture/2026-08-06-web-markdown-incremental-ast-renderer.md), [streaming fence highlighting](../../../.agents/notes/implemented/feature/2026-08-20-web-streaming-fence-highlight.md)).
+
+### Geometry and overflow
+
+The output cards share one geometry model: `white-space: pre` with horizontal scrolling so column-aligned content keeps its alignment, and a head-plus-tail slice behind an expand button past `maxLines` (default 16) so a long body never stretches the card. `TerminalBlock` parses ANSI into React spans with a per-line column buffer for cursor movement, honoring erase-in-line, tab stops, and character width.

 ## Known Limitations and Deferred Work
 
-- **Streaming defers cross-boundary reference resolution** — a reference-style link or footnote whose definition sits on the other side of the incremental freeze boundary renders as literal text while the reply streams; the settled full parse at finalize resolves it. Inline links and references resolved within one parse are unaffected.
-- **Glyph-level icons are redrawn approximations** — the fish logo (and the sparkle held by ui-conversation) come from font glyphs whose vector geometry is not exportable from the local design data; hand-authored recreations stand in until an exact export path exists.
-- **Pill and Input have no design source** — both atoms are self-defined; the sidebar search field and view-tab strip that resemble them are consumer-owned compositions, not these atoms.
-- **No `Active` StateDot variant** — the supported states are done, warning, ongoing, and error.
-- **User-facing copy is required at the render site** — the atoms are zero-Cordis and cannot reach `ctx.locale`, so `HoverCard`, `TerminalBlock`, `JsonTree`, `CodeBlock`, `MarkdownText`, `JsonBlock`, `ConnectionBanner`, `Modal`, `DiffBlock`, `ReadBlock`, `SearchBlock`, and `WebBlock` receive complete localized labels through props. The package owns no language fallback; omission fails typechecking, and each feature maps its typed `t` seat into the primitive's label interface ([decision](../../../.agents/notes/implemented/architecture/2026-08-23-locale-owned-client-ui-copy.md)).
-- **`TerminalBlock` is not a terminal emulator** — it renders settled or still-running command output, not an interactive session: SGR color and attributes are honored, and so are the in-line cursor movements a progress line uses — carriage return, backspace, erase-in-line, tab stops and character width. Absolute cursor positioning, screen clearing, and alternate-screen sequences are stripped. Basic-16 magenta and cyan have no token equivalent and stay literal rgb.

-纯 React 原子组件（零 cordis）：StateDot、DisclosureRow、ic_ds_* 图标、Button/Pill/Menu/Modal/Input、Toast 短时横幅、OnboardingSurface 首次使用接管层（portal 到 body 的遮罩加不透明展示层，在且仅在自身生命周期内保持 `#root` 为 `inert`）、markdown 家族（MessageText/MarkdownText/JsonBlock）、只读 JsonTree 检查器、`useAnchoredMaxHeight` 钩子（把底部锚定的浮层高度收敛到锚点上方的视口空间，并在 resize、scroll 与调用方提供的依赖变化时重新测量）、`useAnchoredPosition` 钩子（让固定定位的浮动面板跟住锚点：测量、偏移、按视口边距钳制，并在捕获阶段滚动、窗口缩放与面板自身尺寸变化时重新定位）、TerminalBlock、DiffBlock、ReadBlock、SearchBlock，以及 WebBlock。
+## 概述
 
-## 悬浮卡片
+`dsh-client-ui-primitives` 是 Web 客户端共享的 React 组件库：每个功能插件都用这些原子组件拼装自己的 UI，而这里没有任何内容依赖 Cordis 或 slot 系统。它提供控件集（按钮、胶囊、输入框、菜单、模态框、Toast 横幅、折叠行、悬浮卡片、连接横幅）、图标字形与品牌标记、锚定浮层用的定位钩子，以及 agent 输出的内容渲染器：带 TeX 公式的 markdown、终端输出、文件读取、差异、搜索结果、网页检索与 JSON 检查。这些渲染器为不受信任的模型输出而设计——原始 HTML 会被丢弃、链接会被失效或安全打开、ANSI 转义序列会被解析而非透传。面向用户的文案通过 label prop 提供；拼装某个原子组件的功能插件负责本地化。
 
-`HoverCard` 通过指针离开宽限期，使采用 portal 渲染的预览在跨过与锚点之间的间隙时仍可触及。消费方还可传入 `copyText`：此时卡片为指针与键盘激活提供按钮语义，其无障碍名称会在 `copyLabel` 前缀后包含该值，通过包内剪贴板辅助函数原样写入该值，并且只有宿主接受写入后，才会临时将内容替换为 `copiedLabel`。与卡片相交的非折叠文本选区会阻止指针点击激活；成功反馈保持卡片原有高度，并随卡片关闭或在一秒后清除。`copyLabel` 和 `copiedLabel` 采用 label prop，是因为这个 zero-cordis 原子组件无法读取应用 locale；省略 `copyText` 时，卡片维持只读且可选择文本的行为。历史依据见[已归档的悬浮卡片复制 Agent Note](../../../.agents/notes/archived/feature/2026-07-31-hover-card-click-copy.md)。

-`Toast` 是顶部的短时横幅：滑入后满不透明度停留三秒，再用一秒淡出，随后调用 `onDone` 由持有方卸载。它渲染 `role="alert"`，带可选的前置图标插槽，文案是必填 prop（零 cordis，由持有方本地化）。它经 body portal 渲染且 `pointer-events: none`，距视口顶部 120px，水平中心跟随可选的 `anchor` 元素（窗口尺寸变化时重测）——composer 传入自己的卡片，横幅因此在聊天列而非整个窗口上居中——不传则回退到视口居中。重复展示同一条消息需要重新挂载，持有方用每次展示递增的序号作为 key，让相同文案重新走完停留与淡出，而不是静默复用已淡出的横幅。`prefers-reduced-motion: reduce` 下去掉滑入，只保留延迟淡出。它的层级高于 ui-attachment 的图片灯箱，预览打开时报出的失败仍然可读。

-## Markdown 渲染
+<a id="use-this-package"></a>
+## 使用本包
 
-`MarkdownText` 通过 React 元素渲染来自不受信任 assistant 输出的 GFM 与 `$…$`、`$$…$$`、`\(…\)` 和 `\[…\]` TeX 公式，公式由 KaTeX 排版并禁用受信任命令；块级同一行 `$$…$$` 是显示公式并支持 `\tag{}`。一个小范围的 micromark 扩展允许由星号标记、以标点结尾的粗体在紧邻的 CJK 文本前闭合，以适应 CJK 文本通常省略 CommonMark 所要求空格的写法；单星号强调、紧邻非 CJK 文本的情况、转义、代码与数学公式仍沿用上游解析行为。它会省略原始 HTML，使相对链接及非 HTTP(S)/mailto 链接失效，以安全的外部链接属性打开 HTTP(S) 链接，并在不发送 referrer 的情况下渲染采用绝对 HTTP(S) URL 的图片；相对路径、绝对本地路径、`file:` URL 与不受支持的 scheme 会保留其 alt 文本。完整内容为绝对 HTTP(S) URL 的行内代码会保留代码样式，并获得同样安全的外部链接；命令、非完整 URL、其他 scheme 与围栏代码仍不会成为链接。可选的 `fileMentions` 解析器让持有该组件的视图为命名真实文件的行内代码添加可点击入口：token 保留代码样式，并获得一个连接到解析所得 opener 的按钮，按钮带有解析器提供的无障碍标签和以完整路径为值的 `title`。渲染器绝不猜测哪些内容像路径：未解析的 token 保持不可交互；文件提及仅应用于已定稿的渲染（流式缓存不得固化可能过期的 handler）；锚点内的 token 也保持不可交互，因为按钮不能嵌套其中。回复流式输出期间，`MarkdownText` 增量解析：除末尾两个块外全部冻结为缓存的 React 元素，每个分片只重新解析其后的源文本尾部，因此每分片的工作量跟随尾部而非整个回复（[机制与 DOM 一致性约定](../../../.agents/notes/implemented/architecture/2026-08-06-web-markdown-incremental-ast-renderer.zh.md)）。表格按列数决定尺寸（对齐 deepsuite chat）：不足四列——或位于 blockquote 内——的表格填满所在列，单元格文本换行收缩至最小可读列宽；四列及以上的表格保持自然宽度、在包裹层内横向滚动，并携带稳定的 `md-table-wide` 类，供宿主布局把包裹层加宽到所在列之外（`dsh-client-ui-conversation` 中聊天转录区的容器查询突破样式）；宽表的横向滚动条在悬停或键盘聚焦（包裹层带 `tabindex="0"`）时才出现、不再常驻（[决策记录](../../../.agents/notes/implemented/feature/2026-08-19-web-markdown-wide-table-view.zh.md)）。`MessageText` 仍是用户创作内容使用的字面文本原语。`extractMarkdownPlainText` 会移除 Markdown 呈现标记以用于紧凑标签，同时将原始 HTML 保留为字面文本。元素间距、响应式图片、表格、链接与行内代码使用与 deepsuite `@deepseek/md` 相同的 `--dsw-alias-markdown-*` / `--dsw-font-markdown-*` token。围栏代码块通过 `CodeBlock` 渲染（语言横幅、复制控件，以及对已注册语法使用 shiki）；回复流式输出期间，围栏随内容增长而增量高亮——每个分片从保存的 grammar state 出发 tokenize 新完成的文本以及仍在增长的最后一行，已完成的行保持其 DOM 不变——定稿渲染换入的 shiki HTML 具有完全一致的 span 树（[决策记录](../../../.agents/notes/implemented/feature/2026-08-20-web-streaming-fence-highlight.zh.md)）。
+只要 Web 客户端需要标准控件或 agent 输出渲染器，就用这些原子组件拼装功能 UI。它们只经 React 渲染，并从主题取得 `--dsw-*` 设计 token，因此无需导入主题或 slot 系统即可适配任意插件。
 
-## 终端输出
+### 控件与图标
 
-`TerminalBlock` 将一条 shell 命令渲染为终端表层：命令的每一行各占一个提示行（缩短后的 `cwd` 标签只出现在第一行，因为视图只知道一个工作目录，而一个 `cd` 就会让后面的行去到别处，标签之后是该行）、命令输出、非零退出码或终止信号对应的状态胶囊，以及写入原始 `output` prop 的复制控件。一枚运行状态 `StateDot` 为整次调用标记一次，位于第一行，以脱离文档流的方式落在卡片以自身左内边距预留的落区中，因此它位于卡片盒之内、提示文字之左。它用到 `StateDot` 的三种状态——`running` 期间为追逐动画，与渲染状态胶囊相同的退出状态为红色，其余为绿色——因此卡片直接陈述其命令是否仍在运行，而不是让人从有无输出中推断；由于 `StateDot` 是 `aria-hidden`，它携带一处视觉隐藏的文本标签。无论多少行都只有一枚状态点是有意为之：退出状态属于整次调用，因此每行一枚就会声称一个视图并不携带的逐行结果。命令文本使用 `white-space: pre`，因此重复空格、制表符与缩进续行都原样呈现，同时该行仍保持单行并以省略号截断。ANSI 转义序列通过 `anser`（打进本包浏览器产物）解析为 React span；光标移动在剥除无显示意义控制符之前先重放进逐行的列缓冲，因为回车与退格**只移动**光标：单是 `100%` 加回车再加 `OK` 显示为 `OK0%`，而 spinner 随重绘写出的 `\x1b[K` 会擦掉尾巴，因此 `100%\r\x1b[KOK` 显示为 `OK`。行内擦除的三种参数形式都被遵循，光标按终端列推进（8 列制表位；emoji 与 CJK 占两列；组合标记不占列），SGR 状态按单元格归一化存储，与终端一致，并跨行延续、在行结束时的状态处收束；基础 16 色前景色映射到 `--dsw-*` token，而 256 色板与真彩色值按字面 rgb 透传。输出保持 `white-space: pre` 并支持横向滚动，因此按列对齐的输出保留其对齐而不会软换行；超过 `maxLines`（默认 16）时折叠为头部切片加尾部切片，由展开按钮控制。原理：[Web 终端卡片笔记](../../../.agents/notes/implemented/feature/2026-07-28-web-terminal-card.zh.md)。
+`Button`、`Pill`、`Input`、`Menu`、`Modal`、`Tooltip`、`DisclosureRow`、`StateDot`、`HoverCard`、`Toast`、`ConnectionBanner`、`RiskConfirmation` 与首次运行接管层 `OnboardingSurface` 覆盖常见的交互形态。`ic_ds_*` 图标集与 `FishLogo`/`BrandWordmark` 标记填充品牌与行内图标 slot。`useAnchoredPosition` 与 `useAnchoredMaxHeight` 让浮动面板与底部锚定浮层始终钳制在视口内并跟随锚点。`HoverCard` 通过指针离开宽限期让采用 portal 的预览在跨过锚点间隙时仍可触及，并可通过 `copyText` prop 提供复制按钮。
 
-## Read 渲染
+### 渲染 agent 输出
 
-`ReadBlock` 将返回的文件窗口渲染为带行号、语法高亮的代码表层：一个粗体路径（或 presenter 提供的标题）横幅加复制控件，其下是内容行，行号槽里是文件自身的行号（窗口化的 read 保留文件本身的编号，因此偏移之后的 read 从大于 1 处起始）。`totalLines` 超过窗口行数时画出 `showing N of M` 提示；超过 `maxLines`（默认 16，与 TerminalBlock 相同的切分算法）时折叠为头部切片加尾部切片，由展开按钮控制。高亮走与 `CodeBlock` 相同的 shiki 路径。原理：[Web read 卡片笔记](../../../.agents/notes/implemented/feature/2026-07-30-web-read-card.zh.md)。
+`MarkdownText` 渲染不可信的 GFM 与 TeX 公式、阻止不安全的链接与图片，并可把已解析的文件提及转换为显式控件。回复流式输出时，它冻结已完成的块，并从保存的 Shiki grammar state 为不断增长的 fence 增量高亮；最终渲染使用相同的 span 树（[增量渲染器](../../../.agents/notes/implemented/architecture/2026-08-06-web-markdown-incremental-ast-renderer.zh.md)、[流式 fence 高亮](../../../.agents/notes/implemented/feature/2026-08-20-web-streaming-fence-highlight.zh.md)）。`TerminalBlock`、`ReadBlock`、`DiffBlock`、`SearchBlock` 与 `WebBlock` 把对应的工具结果意图渲染为带复制控件、溢出处理及适用时 ANSI 处理的卡片。`JsonTree` 与 `JsonBlock` 以只读方式检查 JSON 值；`MessageText` 仍是用户创作内容的字面文本原语。
 
-## Diff 渲染
+### 本地化文案
 
-`DiffBlock` 将一次文件改动渲染为内联 diff 表层：每个文件一个粗体路径头、删除行（`- `，error token）在新增行（`+ `，success token）之上、同文件第二个 hunk 前一个 `⋯` gap，以及暗色 `└ +A -R · N file(s)` 页脚。各行使用 `white-space: pre` 并横向滚动，因此源码行保留其缩进而不软换行；超过 `maxLines`（默认 16，与 `TerminalBlock` 相同的切分算法）时折叠为头部切片加尾部切片，由展开按钮控制。新建（`oldText: null`）没有删除侧。复制控件写入带前缀的 diff 文本（路径头、`- `/`+ ` 行、gap），使多文件复制保持可归属，并浮在右上角而非占据自己的 banner 行。几何结构与 `CodeBlock`/`TerminalBlock` 一致。原理：[Web diff 卡片笔记](../../../.agents/notes/implemented/feature/2026-07-30-web-diff-card.zh.md)。
+这些原子组件无法读取应用 locale，因此每段面向用户的文案都必须通过 label prop 提供。`HoverCard`、`TerminalBlock`、`JsonTree`、`CodeBlock`、`MarkdownText`、`JsonBlock`、`ConnectionBanner`、`Modal`、`DiffBlock`、`ReadBlock`、`SearchBlock` 与 `WebBlock` 接收完整的本地化 label。本包不拥有语言回退；遗漏会导致类型检查失败，各功能会把带类型的 `t` 席位映射到 primitive 的 label 接口。
 
-## 搜索结果
+-----
 
-`SearchBlock` 渲染一次已完成的搜索，并通过 `kind` 判别，由一个组件处理两种结果。`matches`（grep）将每个文件显示为粗体路径头及其 `lineNumber: line` 行，各文件组均可折叠；`paths`（glob）显示扁平的路径列表。两者都摊平成一个行列表，由高度上限对其做头尾切片（默认 16，与 `TerminalBlock` 相同的切分算法），且都不软换行：较长的匹配行或路径会横向滚动而非折行。当工具截断结果时，banner 摘要会包含截断前的总数（grep 为 `显示 X / 共 N 处匹配 · K 个文件`，glob 为 `显示 X / 共 N 个路径`），使卡片绝不把截断后的结果呈现为完整结果；无论是否触及上限或哪些组处于折叠状态，复制控件都会写入完整的结构化结果。几何结构与 `CodeBlock`/`TerminalBlock` 一致。原理：[Web 搜索卡片笔记](../../../.agents/notes/implemented/feature/2026-07-30-web-search-card.zh.md)。

-`WebBlock` 渲染一次已完成的 web 检索，用一个组件绘制 `web` 渲染意图的两种 kind（由 `kind` 判别）。`search` 在有序引用列表上方显示可选的提供方回答（通过 `MarkdownText`）：每个 source 是一个安全外链，以其标题为标签，或以其主机名为标签，当 URL 无法解析或没有主机名（`file:`/`data:` URL）时回退到原始 URL，因此标签绝不为空；其下渲染 snippet 与发布日期。只有 http(s) URL 会成为锚点（设置 `target`/`rel`）——这是 `MarkdownText` 对不受信任链接所用 allowlist 的 http(s) 子集（该 allowlist 还允许 `mailto:`，此处排除）；任何其他 URL 渲染为纯文本。整份列表渲染在一个定高滚动容器里（`max-height: 320px`、`overflow-y: auto`），因此超出该高度的列表在原地纵向滚动，而不是把卡片撑高；`<li value>` 固定每个 source 的引用编号，从 1 起连续，而不依赖 `<ol>` 的隐式计数。当一次 search 合法地返回无 answer 且无 source 时，卡片显示一个明确的空状态提示，而不是空的 `<ol>`（chat 行不呈现原始 result content）。`fetch` 显示一个紧凑摘要：带链接的最终 URL 及其 HTTP 状态。两者都会标记一次被截断的检索。原理：[Web result 卡片笔记](../../../.agents/notes/implemented/feature/2026-07-30-web-result-card-frontend.zh.md)与[来源滚动笔记](../../../.agents/notes/implemented/feature/2026-08-03-web-search-source-scroll.zh.md)。

+### 流式 markdown
+
+回复流式输出期间，`MarkdownText` 增量解析：除末尾两个块外全部冻结为缓存的 React 元素，每个分片只重新解析其后的源文本尾部，因此每分片的工作量跟随尾部而非整个回复。不断增长的 fenced block 会从已保存的 Shiki grammar state 加上尚未完成的最后一行继续分词；已完成行保留其 DOM，定稿渲染则使用相同的 span 树。定稿时的全量解析还会解析跨过冻结边界的引用（[增量渲染器](../../../.agents/notes/implemented/architecture/2026-08-06-web-markdown-incremental-ast-renderer.zh.md)、[流式 fence 高亮](../../../.agents/notes/implemented/feature/2026-08-20-web-streaming-fence-highlight.zh.md)）。
+
+### 几何与溢出
+
+输出卡片共享同一套几何模型：`white-space: pre` 并横向滚动，让按列对齐的内容保持对齐；超过 `maxLines`（默认 16）时折叠为头部切片加尾部切片，由展开按钮控制，长正文不会撑高卡片。`TerminalBlock` 把 ANSI 解析为 React span，并带逐行列缓冲处理光标移动，遵循行内擦除、制表位与字符宽度。

-Unified Web `@file` and `@session` source. The browser starts the `fileReferences/list` and `sessionReferenceResolver/candidates` Remote calls together for an unquoted token, deterministically orders files before sessions with locale-registered folder/file/session labels, and renders the rows under non-selectable file and session section headings without a redundant raw `reference` source title. Either failed candidate domain degrades independently. An open `@"…` token searches files only.
+## Summary
 
-File picks preserve the natural text defined by the shared `@path` grammar as their hidden serialized and clipboard form. A file closes completion as an atomic inline reference displayed with a file glyph, business-color filename, and no capsule. A directory remains plain editable path text with a folder glyph and keeps the menu active at its trailing slash so the user can descend another level. Paths containing whitespace use `@"path with spaces"`, and a quote the user opened explicitly remains quoted.
+`dsh-client-ui-reference` is the unified Web `@file` and `@session` reference source: it registers the `reference` entry in the composer's inline-suggestion machinery so a user typing `@` sees file and session candidates in one list. Files order before sessions, sections are labelled with locale-registered terms, and either candidate domain can fail independently without blocking the other. A pick inserts an atomic inline reference — a file closes completion with an editable path text, a session inserts a canonical mention — so the sent text is the same natural text the shared grammar defines. Selecting a session routes through the session-reference service, which validates the mention and captures model context at the pre-step boundary; this package itself registers no prompt or tool.
 
-Session picks insert an atomic inline reference whose hidden `ref` and clipboard representation are the canonical `@[label](dsh-session:…)` mention returned by the Host. Its visible form is a chat-bubble glyph plus the business-color session title, without a capsule; serialization never reconstructs identity from that title. Ordinary send carries the canonical mention through `session.prompt`; the session-reference service validates it and captures model context at `agent/pre-step`.

+## Use this package
+
+The source is active whenever the composition mounts this package and a Host `ctx.fileReferences` provider is available. Type `@` followed by an unquoted token to see files first, then sessions; open `@"…` to search files only. The candidate list is a completion menu, not a search result page: pick once and keep typing.
+
+### What a pick inserts
+
+A file closes completion as an atomic inline reference displayed with a file glyph and business-color filename. A directory remains plain editable path text with a folder glyph and keeps the menu active at its trailing slash, so you can descend another level.

 # @deepseek-ai/dsh-client-ui-renderer
 
 English | [中文](README.zh.md)
 
-The browser Cordis plugin that owns the React rendering layer. [`dsh-client-web`](../web/README.md) renders a framework-free boot page and loads the complete client plugin roster; after every entry activates, it calls `ctx.uiRenderer.mount(container)`. This package provides that service, installs the slot renderer, hydrates the existing boot DOM, switches to the assembled application before the next paint, and returns the React root's unmount disposer.
+## Summary
 
-The client entry also owns the React implementation of slot outlets, session providers, and observable-to-uSES binding. Business plugins pass bare observable sources through typed slot `hooks`; the renderer binds them at the outlet. The renderer performs the sole context-level `renderSlot('root')` call; the registered root occupant owns product layout and document metadata. React, React DOM, Cordis, ui-slots, and ui-primitives retain one browser identity through the web shell's static module table; this package arrives as a dynamic client bundle.
+`dsh-client-ui-renderer` mounts the assembled dsh web client GUI: after the complete client plugin roster settles, the boot kernel calls `ctx.uiRenderer.mount(container)`, which hydrates the framework-free boot page and switches to the full React application before the next paint. Business plugins stay plain React components that receive session and workspace data through typed props and never wire subscriptions themselves — the renderer binds the runtime's bare observable sources into selector hooks at the slot outlets. The web shell and the boot kernel are its only direct consumers, so a composition needs it exactly when it wants a React-rendered GUI.

+## Use this package
+
+This package is infrastructure: the web shell and the boot kernel are its only direct consumers. A composition needs it whenever it wants a React-rendered GUI — `dsh-client-web` loads the roster, waits for every entry to activate, then calls `ctx.uiRenderer.mount(container)`.
+
+### What mounting does
+
+`mount(container)` installs the slot renderer, hydrates the existing boot DOM when present, renders the assembled application into the container before the next paint, and returns a disposer that unmounts the React root. The renderer performs the sole context-level `renderSlot('root')` call; the registered root occupant owns product layout and document metadata.
+
+### For business plugins
+
+A business plugin registers a component through the slot system; the renderer binds the runtime's session and workspace observable sources into selector hooks at the outlet. The plugin receives the standard session props (session id, conversation snapshot hooks) through its composed props — it never imports the renderer or touches React internals.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+The package realizes one boundary: the object layer (runtime, React-free) owns business state; this renderer is the only place ctx-to-React integration happens — slot renderer, `SessionProvider`, and the `useSyncExternalStore` adapter.
+
+### Activation and mount
+
+The plugin activates after `slots`, `sessions`, and `layout`; it installs `createSlotRenderer()` and reflects the `uiRenderer` service. `mountApp` looks for the boot kernel's `[data-dsh-boot]` element: when present it hydrates through `BootHandoff` (a one-frame pass-through that preserves the loading DOM), otherwise it creates a fresh root and flushes the render synchronously.
+
+### Slot bindings
+
+`createSlotRenderer` connects the slot registry to React: entry lists become reactive sources, and each outlet renders through the installed renderer. Business plugins pass bare observable sources through typed slot `hooks`; the renderer binds them at the outlet via the uSES adapter.
+
+### Identity
+
+React, React DOM, Cordis, ui-slots, and ui-primitives retain one browser identity through the web shell's static module table; this package arrives as a dynamic client bundle.

-负责 React 渲染层的浏览器 Cordis 插件。[`dsh-client-web`](../web/README.zh.md) 渲染不依赖框架的启动页并加载完整的客户端插件名册；所有 entry 激活后，它调用 `ctx.uiRenderer.mount(container)`。本包提供该服务、安装 slot 渲染器、hydrate 现有启动 DOM、在下一次绘制前切换到组装完成的应用，并返回 React 根的卸载 disposer。
+## 概述
 
-client entry 还持有 slot outlet、会话 provider 以及 observable 到 uSES 绑定的 React 实现。业务插件通过带类型的 slot `hooks` 传递裸 observable source；渲染器在 outlet 处完成绑定。渲染器执行全程序唯一一次上下文级 `renderSlot('root')` 调用；已注册的 root 占位者拥有产品布局与文档元数据。React、React DOM、Cordis、ui-slots 和 ui-primitives 通过 web 外壳的静态模块表保持同一浏览器身份；本包则以动态客户端 bundle 到达。
+`dsh-client-ui-renderer` 挂载组装完成的 dsh Web 客户端 GUI：完整客户端插件名册稳定后，启动内核调用 `ctx.uiRenderer.mount(container)`，它会 hydrate 不依赖框架的启动页，并在下一次绘制前切换到完整的 React 应用。业务插件仍是接收类型化 props 的普通 React 组件，通过 props 获取会话与 Workspace 数据，永远不需要自行接线订阅——渲染器在 slot outlet 处把运行时的裸 observable source 绑定为 selector 钩子。Web 外壳与启动内核是它仅有的直接消费方，因此只要组合需要 React 渲染的 GUI，就需要它。

+## 使用本包
+
+本包属于基础设施：Web 外壳与启动内核是它仅有的直接消费方。只要组合需要 React 渲染的 GUI，就需要它——`dsh-client-web` 加载名册，等待每个 entry 激活，然后调用 `ctx.uiRenderer.mount(container)`。
+
+### 挂载做什么
+
+`mount(container)` 会安装 slot 渲染器、在存在时 hydrate 现有启动 DOM、在下一次绘制前把组装后的应用渲染进容器，并返回一个卸载 React 根的 disposer。渲染器执行全程序唯一一次上下文级 `renderSlot('root')` 调用；注册的根占用方拥有产品布局与文档元数据。
+
+### 对业务插件
+
+业务插件通过 slot 系统注册组件；渲染器在 outlet 处把运行时的会话与 Workspace observable source 绑定为 selector 钩子。插件通过其组合 props 收到标准会话 props（session id、对话快照钩子）——它绝不导入渲染器，也不触碰 React 内部机制。

+<a id="understand-the-implementation"></a>
+## 理解实现
+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本包实现一条边界：对象层（runtime，无 React）拥有业务状态；这里是 ctx 到 React 集成唯一发生的位置——slot 渲染器、`SessionProvider` 与 `useSyncExternalStore` 适配器。
+
+### 激活与挂载
+
+插件在 `slots`、`sessions` 与 `layout` 就绪后激活；它安装 `createSlotRenderer()` 并 reflect `uiRenderer` 服务。`mountApp` 会查找启动内核的 `[data-dsh-boot]` 元素：存在时经 `BootHandoff`（一个保留加载 DOM 的单帧透传）hydrate，否则创建全新 root 并同步 flush 渲染。
+
+### Slot 绑定
+
+`createSlotRenderer` 把 slot 注册表连接到 React：条目列表成为响应式 source，每个 outlet 经已安装的渲染器渲染。业务插件通过带类型的 slot `hooks` 传递裸 observable source；渲染器经 uSES 适配器在 outlet 处完成绑定。
+
+### 身份

 # @deepseek-ai/dsh-client-ui-settings-general
 
 English | [中文](README.zh.md)
 
-Settings shell, ownerless copy, and durable product-onboarding namespace. It occupies `sidebar.settings` with the trigger chrome and modal settings panel, projects the `settings.section` ledger into the navigation and the `settings.onboarding` ledger into one mounted step at a time, and registers everything on the Settings pages that belongs to no single feature — the trigger/header/close chrome content, the local configuration-file action, the General section and its `settings.general.item` slot, and the `settings` dictionaries. The slot types it renders into belong to ui-settings, the settings domain base; only the shell's own contract types live here, because they reference ui-sidebar's slot type and the base layer must depend on no `ui-*` package. Feature-owned rows (Permission, Language, Appearance), sections (Models), and conditional onboarding steps stay with their feature packages.
+## Summary
 
-The shell ships no onboarding copy of its own — all text arrives from registrants. Nav labels may be locale-following thunks, so the nav projection resolves them through `resolveSlotLabel` and re-renders on the section ledger bump or the locale revision (an optional `ctx.get('locale')` read; no hard locale dependency). The onboarding ledger projects in ascending order and mounts exactly one step at a time. Visible steps own their dialog chrome and app-root `inert` lifecycle; a mounted step still resolving private facts renders null, so nothing paints or blocks while it decides. The active registrant receives its id, `complete()`, and an `openSection(id)` callback; completing or skipping transfers ownership to the next entry. Registrants own durable completion, capability readiness, copy, mutations, and their visible wrapper, so independently registered flows cannot stack and the shell does not become a second configuration fact source.
+`dsh-client-ui-settings-general` is the settings shell of the dsh web client: the Settings panel opens from the sidebar's bottom control with the trigger chrome and modal shell, the navigation is built from the sections features contribute, and first-run users are walked through one onboarding step at a time. It also registers everything on the Settings pages that belongs to no single feature: the trigger/header/close chrome content, the local configuration-file action, the General section and its `settings.general.item` slot, and the `settings` dictionaries. Feature-owned rows (Permission, Language, Appearance), sections (Models), and conditional onboarding steps stay with their feature packages; the shell itself ships no onboarding copy of its own.

+## Use this package
+
+Users reach the shell through the sidebar's bottom Settings control; feature plugins contribute their pages and onboarding steps through the slot ledgers this shell projects. The shell renders the modal panel, the navigation built from `settings.section` entries, and exactly one mounted onboarding step at a time.
+
+### The General section
+
+The General section holds rows registered into `settings.general.item` by feature packages — it has no built-in rows. Feature plugins own the row copy and behavior; the shell only provides the section and its slot. The Appearance row, for example, lives in ui-theme.
+
+### Opening the configuration file
+
+On a loopback browser, the shell renders **Open configuration file** only when the Host confirms that a provider-owned local document can be prepared. The action opens that document in the native text editor (bypassing the browser file association on macOS). Remote browsers never register the action and never issue the privileged settings read.
+
+### Onboarding steps
+
+The onboarding ledger projects in ascending order and mounts exactly one step at a time. Registrants own durable completion, capability readiness, copy, mutations, and their visible wrapper, so independently registered flows cannot stack and the shell does not become a second configuration fact source. Visible steps own their dialog chrome and app-root `inert` lifecycle.

+<details>
+<summary>Implementation internals — click to expand</summary>
+
+The shell owns the chrome and the projections; every piece of content and copy belongs to a registrant.
+
+### Ledger projections
+
+The navigation is a projection of the `settings.section` ledger; nav labels may be locale-following thunks, resolved through `resolveSlotLabel` and re-rendered on the section ledger bump or the locale revision (an optional `ctx.get('locale')` read; no hard locale dependency). The onboarding ledger projects in ascending order; the active registrant receives its id, `complete()`, and an `openSection(id)` callback, and completing or skipping transfers ownership to the next entry.
+
+### Document availability
 
 On a loopback page, the Client loads the provider's `hasDocument` capability through `settings.describe` and renders **Open configuration file** only when the Host confirms that a provider-owned local document can be prepared. The action sends the pathless, browser-authenticated `settings.openDocument` request; the Host resolves the provider path again, materializes an absent document, and hands it to a native text editor (`open -t` on macOS, bypassing a browser file association; the desktop file association on Linux and Windows; Windows association after `wslpath -w` translation on WSL). Open failures keep the action available and render a localized error. Reopening the dialog or reconnecting refreshes availability after a transient read failure or Host topology change. Non-loopback pages retain the Client policy that withholds this native action and its settings read.
 
-The Host half registers `ui-onboarding` in the user-settings seam. The welcome step contributed by `ui-settings-models` reads and writes its `welcomeNoticeVersion` through the existing public settings boundary; the shell itself remains policy-free.

 # @deepseek-ai/dsh-client-ui-settings-general
 
 [English](README.md) | 中文
 
-设置外壳、无特定功能归属文案与持久化产品引导 namespace。它以触发控件和模态设置面板占用 `sidebar.settings`，把 `settings.section` 账本投影成导航、把 `settings.onboarding` 账本投影成每次只挂载一个步骤的引导流程，并在设置页面上注册所有不属于单一功能的内容：触发器、标题栏与关闭控件内容、本地配置文件操作，「通用」分区及其 `settings.general.item` slot，以及 `settings` 字典。它渲染进的那些 slot 类型归 ui-settings——设置领域底座——所有；只有外壳自身的契约类型放在这里，因为它们引用 ui-sidebar 的 slot 类型，而底座不得依赖任何 `ui-*` 包。归具体功能所有的行（「权限」、「语言」、「外观」）、分区（「模型」）和条件式首次使用引导步骤仍由各自的功能包提供。
+## 概述
 
-外壳不自带引导文案：所有文本都来自注册方。导航 label 可以是跟随语言的 thunk，因此导航投影经 `resolveSlotLabel` 解析，并在分区账本更新或 locale revision 变化时重新渲染（`ctx.get('locale')` 可选读取，无硬 locale 依赖）。首次使用引导记录按升序投影，每次只挂载一个步骤；可见步骤自行持有弹窗框架和应用根节点 `inert` 生命周期。已挂载但仍在判定私有事实的步骤渲染 null，因此判定期间不绘制也不阻塞任何内容。当前注册方会收到该条目的 id、`complete()` 和 `openSection(id)` 回调；完成或跳过当前步骤后，所有权转交给下一项。持久化完成状态、能力就绪状态、文案、变更操作以及可见包装均由注册方持有，因此独立注册的流程无法堆叠，外壳也不会成为第二个配置事实来源。
+`dsh-client-ui-settings-general` 是 dsh Web 客户端的设置外壳：Settings 面板从侧边栏底部的控件打开，带触发控件与模态外壳；导航由各功能贡献的分区构建；首次运行的用户一次只走一个引导步骤。它还注册设置页面上所有不属于单一功能的内容：触发器、标题栏与关闭控件界面框架、「本地配置文件」操作、「通用」分区及其 `settings.general.item` slot，以及 `settings` 字典。归具体功能所有的行（「权限」、「语言」、「外观」）、分区（「模型」）与条件式首次使用引导步骤仍由各自的功能包提供；外壳本身不自带任何引导文案。
 
-在 loopback 页面上，Client 通过 `settings.describe` 加载提供方的 `hasDocument` 能力，且只有在 Host 确认可准备好一份由提供方持有的本地文档时才渲染**打开配置文件**。该操作发送无路径参数且经浏览器认证的 `settings.openDocument` 请求；Host 会再次解析提供方路径、在文档缺失时将其创建出来，并交给原生文本编辑器（macOS 上使用 `open -t`，绕过浏览器文件关联；Linux 和 Windows 上使用桌面文件关联；WSL 上经 `wslpath -w` 转换后使用 Windows 文件关联）。打开失败时该操作仍可使用，并渲染本地化错误。临时读取失败或 Host 拓扑变化后，重新打开对话框或重新连接会刷新可用性。非 loopback 页面保留 Client 策略，不提供该原生操作及其 settings 读取。

+## 使用本包
+
+用户通过侧边栏底部的 Settings 控件进入外壳；功能插件通过本外壳所投影的 slot 账本贡献自己的页面与引导步骤。外壳渲染模态面板、由 `settings.section` 条目构建的导航，以及每次只挂载一个的引导步骤。
+
+### 「通用」分区
+
+「通用」分区承载由功能包注册进 `settings.general.item` 的行——它没有内置行。功能插件拥有行文案与行为；外壳只提供分区及其 slot。例如「外观」行位于 ui-theme。
+
+### 打开配置文件
+
+在回环浏览器上，只有当宿主确认可准备好一份由提供方持有的本地文档时，外壳才渲染**打开配置文件**。该操作会在原生文本编辑器中打开该文档（macOS 上绕过浏览器文件关联）。远程浏览器从不注册该操作，也从不发起这项特权设置读取。
+
+### 引导步骤
+
+引导账本按升序投影，每次只挂载一个步骤。注册方持有持久化完成状态、能力就绪状态、文案、变更操作与可见包装，因此独立注册的流程无法堆叠，外壳也不会成为第二个配置事实来源。可见步骤自行持有弹窗框架与应用根节点 `inert` 生命周期。

+
+外壳拥有界面框架与投影；每段内容与文案都属于某个注册方。
+
+### 账本投影
+
+导航是 `settings.section` 账本的投影；导航 label 可以是跟随语言的 thunk，经 `resolveSlotLabel` 解析，并在分区账本更新或 locale revision 变化时重新渲染（`ctx.get('locale')` 可选读取，无硬 locale 依赖）。引导账本按升序投影；当前注册方会收到该条目的 id、`complete()` 与 `openSection(id)` 回调，完成或跳过当前步骤后，所有权转交给下一项。
+
+### 文档可用性
+
+在 loopback 页面上，Client 通过 `settings.describe` 加载提供方的 `hasDocument` 能力，且只有在 Host 确认可准备好一份由提供方持有的本地文档时才渲染配置文件操作。该操作发送无路径参数且经浏览器认证的 `settings.openDocument` 请求；Host 会再次解析提供方路径、在文档缺失时将其创建出来，并交给原生文本编辑器（macOS 上使用 `open -t`，绕过浏览器文件关联；Linux 和 Windows 上使用桌面文件关联；WSL 上经 `wslpath -w` 转换后使用 Windows 文件关联）。打开失败时该操作仍可使用，并渲染本地化错误。临时读取失败或 Host 拓扑变化后，重新打开对话框或重新连接会刷新可用性。非 loopback 页面保留 Client 策略，不提供该原生操作及其 settings 读取。
+
+### 宿主端
 
 宿主端在用户设置 seam 中注册 `ui-onboarding`。`ui-settings-models` 提供的欢迎步骤通过既有公开 settings 边界读写其中的 `welcomeNoticeVersion`；外壳本身仍不持有产品策略。

 # @deepseek-ai/dsh-client-ui-settings-models
 
 English | [中文](README.zh.md)
 
-Models settings and product-onboarding plugin. The same client Cordis plugin registers the Models page plus two ordered first-run dialogs: a versioned internal-testing notice and the conditional official-DeepSeek credential step. Both steps share one modal wrapper and remain sequenced by `settings.onboarding`. The Models plane joins three wire domains into one shared snapshot — `llm.providers` (the configurable-provider directory with each route's live/dormant state), `settings.describe` (serialized schemas, layered redacted values, secret slots), and `credentials.describe` (value-free configured/source/writable badges) — and renders provider rows with one editor card at a time, without presenting route liveness as provider status.
+## Summary
 
-When the Host advertises the `subagent-model-selection` settings namespace, Models also renders a localized switch above the provider rows. It defaults off and writes only `{ enabled }` through `settings.update` with the namespace revision. The Host samples it while composing a new top-level Session; changing it does not reconfigure running Sessions, while child Sessions inherit their parent's recorded decision.
+`dsh-client-ui-settings-models` is the Models settings page of the dsh web client: users configure API keys (stored write-only under the profile's credential reference), edit each provider's model list, and hand-declare custom pi-ai routes, with provider rows and one editor card at a time. The page joins the provider directory, the settings document, and the credential descriptions into one shared snapshot, so a row's state stays consistent across all three. It also walks first-run users through two ordered dialogs — a versioned internal-testing notice and the conditional official-DeepSeek credential step.
 
-Rows are the *configured* providers (their profile resolves in the owning namespace); a whole-section provider whose key is not configured anywhere renders as its open setup card instead of a row, but only in the first-run posture — while no provider is registered with the credential its profile names — and only until the user closes that card, after which it is an ordinary row carrying the missing-key dot. Each card kind owns its own open state, so closing one never discards a draft in another. The add flow is a card carrying the dormant-directory provider select — a bare-mounted `llm-pi-ai` offers its whole installed catalog before any route exists. The pi-ai card additionally edits that route's **model list** and can ask the provider what it serves. A row labels API-key state with a green solid dot only when a referenced credential is confirmed configured, and with a red solid dot only when a named reference is confirmed missing; reference-free provider-native authentication and unavailable credential enrichment remain unmarked. The editor is a hand-written card per adapter family: the primary field is a single **API key** input — the page never asks for an environment-variable name; a typed key stores **write-only** through `credentials.set` under the profile's reference, deriving `<ROUTE>_API_KEY` when the profile has none, and the pi-ai profile records that derivation as `apiKeyEnv`, so `settings.yaml` never carries a key value. Leaving a new pi-ai provider's key blank saves a reference-free profile and therefore preserves provider-native authentication such as the Bedrock credential chain or Vertex ADC. A successful Apply emits a local accessible status message without echoing secret material. The collapsed 自定义设置 fold carries the curated extras — `baseURL` for both families (the deepseek placeholder shows the public endpoint), each adapter's model catalog, and the **display name** and **API protocol** of a pi-ai route the adapter does not ship. Those two are what a hand-declared route names for itself: the create card asks for both because nothing can default them, so the editor reaches both rather than leaving them to `settings.yaml`. Clearing the name unsets it and the route falls back to its id, which is what the placeholder shows; the protocol has no such fallback. A catalog route gets neither — it defaults its name from its catalog entry, and its models each carry their own protocol, so a route-level one could only override every one of them. The Provider ID stays fixed: it is the settings key, the name every other namespace and every logged session references, and the stem of a credential reference the page cannot read back to move. Reasoning effort is deliberately NOT among them: it is a per-model capability and the models under one provider disagree about which levels they accept, so a provider-scoped control could only be set to a value some of them reject — which would hide even the models that support the level. The composer's model picker offers each model its own levels, and a switch there records provider, model, and effort together as the default for the next session. The profile field stays in `settings.yaml` for a deployment that knows its route. Each DeepSeek row edits `id`, optional display `name`, and optional `contextWindow`/`maxTokens`; existing fields outside that curated set survive edits, while every other profile field stays owned by `settings.yaml`. A row is deletable only when the user layer alone carries it (removal restores the composition base), and its localized confirmation dialog names the provider in the title, description, and final action. A row is tagged **Custom** when the directory entry says the owning adapter ships nothing under that key. The tag follows that answer alone: having a stored profile does not make a route custom — narrowing a shipped provider's models stores one too — and an adapter that reports nothing leaves its rows untagged rather than being read as shipped.
+## Table of Contents
 
-The notice step owns its exact copy in `src/client/locales.ts` and its acknowledgement version in `src/onboarding-copy.ts`. On loopback it compares and writes `ui-onboarding.welcomeNoticeVersion` through the existing settings API; only an explicit Continue records the current version. A non-loopback browser cannot use that Host-only namespace, so acknowledgement is process-local and the notice returns after reload.

-After that notice completes, the DeepSeek step projects first-run readiness from the same joined Models snapshot. ANY provider the user can already reach ends it without rendering — a registered route whose named credential reference is stored, including a read-only launch-environment credential, or one whose profile names no reference and therefore authenticates natively. Only a user with none is asked for the official DeepSeek key. A mounted, active adapter with a missing writable reference renders the existing `ProviderEditor` in credential-only mode inside the shared onboarding modal; `credentials.set` stays the only secret write, and no provider settings are changed. Configure later completes only this coordinator pass. An absent adapter, inactive route, failed join, read-only deployment, or unusable settings or credential capability completes the step without rendering; Models remains the diagnostic surface.
+-----
 
-Every edit lands as `settings.mutate` path ops against the stored section — a set per changed field, an unset per cleared one, and a single unset for a deleted provider row. The page only ever holds the REDACTED descriptor, so it mutates the fields it can see rather than rebuilding a section. DeepSeek's `models` is one replace-by-value array: the editor shows inherited effective rows until the first model edit materializes the complete array in the user layer, while reset unsets that override. A row carries the model id and display name; its context window and output cap sit behind the row's own disclosure, with the same fields the pi-ai provider form uses. Either capacity is typed as a count with an optional decimal `K` or `M` suffix (`256K`, `1M`; `1M` is 1000K) and stored as the plain count, spelled back in the shortest form that round-trips. Empty ids, duplicate ids, empty explicit names, and unreadable, non-positive, or fractional capacities fail before any write. A typed API key is judged on its own field the same way: after trimming, it must be non-empty and every character must be printable ASCII (`[\x21-\x7E]`), which is exactly what an HTTP header value can carry — the twin of `normalizeApiKey` in `@deepseek-ai/dsh-llm`, mirrored here because the source-plane split forbids importing it. A value matching a pasted `NAME=value` environment line or wrapped in matching quotes is refused as the same format failure; that pasted-line check runs only in the browser, since a false positive in a resolver would leave the environment refusing the key as well. A field holding only whitespace fails rather than being silently dropped, while an empty field is not a failure at all: it means keep the stored key on an editor card, and authenticate some other way on a create card. A refused key blocks both the write and the endpoint interrogation, so the page never spends a round trip to be told what the field already says. Each settings write carries the card's current `revision`, so a concurrent write from another tab or an external `settings.yaml` edit is refused as `settings-conflict`; after settings commit, the card adopts the returned redacted user subtree and revision before storing the credential, which makes a failed credential stage retry only that stage. Deletion removes a configured, writable credential only when the profile names the page's derived `<ROUTE>_API_KEY` target, then unsets the profile; both operations are idempotent, and a partial failure remains in the identified confirmation dialog for retry. Environment credentials, custom references, and credentials whose target cannot be identified remain untouched. Once loaded, the page subscribes directly to forwarded `settings/document-updated`, `credentials/reference-updated`, and `llm/adapters-updated` owner events, plus local `connection/reset`, so an external `settings.yaml` edit, a second tab, or a settings-born route converges without polling.
+<a id="use-this-package"></a>
+## Use this package
 
-## Model list and endpoint interrogation
+Open the Models page from the Settings navigation to see every configured provider as a row. A whole-section provider whose key is not configured anywhere renders as its open setup card instead, but only in the first-run posture and only until the user closes that card. Each card kind owns its own open state, so closing one never discards a draft in another.
 
-A pi-ai profile's `models` list is edited on the card: one row per model showing its id and display name, with the context window and output cap behind a per-row disclosure and two label-free actions — expand and delete — on the right. An empty list means "serve this route's built-in catalog", so a row is only ever added deliberately; clearing a capacity drops it rather than storing a value the schema would reject, and the adapter's route-level fallbacks size whatever configuration leaves out — an empty capacity shows those fallbacks' magnitude as its placeholder, a hint rather than a mirror, since the field counts `K` as 1000 and a deployment may override them. A capacity that is not a positive integer is simply not stored.
+### API keys
 
-**Fetch available models** asks `llm.discoverModels` about the endpoint the form **currently shows**, including a base URL edited but not yet saved and a key typed but not yet stored, so adding a provider is one pass instead of save-then-return. The reply opens a picker rather than being written: candidates already configured start unchecked, so adopting a selection never overwrites a capacity the user corrected. **Select all** / **Deselect all** changes only the picker's current checkboxes; nothing is written until **Add selected**. A provider that cannot be interrogated is a detour, not a dead end — the adapter's own message appears beside the rows, which stay editable by hand.
+The primary field on an editor card is a single **API key** input — the page never asks for an environment-variable name. A typed key stores write-only through `credentials.set` under the profile's reference, deriving `<ROUTE>_API_KEY` when the profile has none, and the pi-ai profile records that derivation as `apiKeyEnv`, so `settings.yaml` never carries a key value. Leaving a new pi-ai provider's key blank saves a reference-free profile and preserves provider-native authentication (for example the Bedrock credential chain or Vertex ADC). A row labels API-key state with a green solid dot only when a referenced credential is confirmed configured, and with a red solid dot only when a named reference is confirmed missing. A successful Apply emits a local accessible status message without echoing secret material.
 
-**Add a custom provider** declares a route pi-ai does not ship. It is its own card rather than the editor with extra fields, because the route id is being chosen here and the settings address does not exist until it is: one `settings.mutate` sets the whole profile at `providers.<route>`, and the key travels separately through `credentials.set` under the same `<ROUTE>_API_KEY` derivation an existing provider uses. What a hand-declared route cannot default gates the create button — a unique **Provider ID**, an endpoint, a protocol, and at least one uniquely-identified model — so the failure names the field while the user is still looking at it. The id must start with a lowercase letter, because it is also the stem of the derived credential reference and a reference is a POSIX shell identifier: a digit-leading id otherwise passes every check this card makes and then fails at the credential seam with a raw regular expression. Capacities do not gate it: the adapter's fallbacks size a model the endpoint described by id alone, which is what most listings return. The protocol choices are read out of the namespace's own schema rather than a wire field or a constant, so they cannot drift from the ones the adapter accepts. The card records the conventional `apiKeyEnv` reference only when a key is typed, the same rule the editor applies, so a route declared for provider-native authentication is not born pointing at a reference nothing will ever set. When the profile write lands but the key write fails, the provider already exists: the card settles the fields describing it, retries the credential alone — re-running the profile write would carry the revision that write just superseded, so the Host would answer `settings-conflict` and the key could never be stored from here — and reports the created provider even if the user then cancels.
+### Editing a provider
 
+The collapsed 自定义设置 fold carries the curated extras: `baseURL` for both families (the deepseek placeholder shows the public endpoint), each adapter's model catalog, and the **display name** and **API protocol** of a pi-ai route the adapter does not ship. The Provider ID stays fixed: it is the settings key, the name every other namespace and every logged session references, and the stem of a credential reference the page cannot read back to move. Reasoning effort is deliberately not among the editable fields: it is a per-model capability, so a provider-scoped control could only be set to a value some models reject. Each DeepSeek row edits `id`, optional display `name`, and optional `contextWindow`/`maxTokens`; existing fields outside that curated set survive edits.
+
+### Subagent model selection
+
+When the Host advertises the `subagent-model-selection` settings namespace, Models shows a localized switch above the provider rows. The switch defaults off and writes only `{ enabled }` through `settings.update` with the namespace revision. The Host samples the value when it composes a new top-level Session, so changing it does not reconfigure running Sessions. Child Sessions inherit their parent's recorded decision.
+
+### Adding and deleting providers
+
+The add flow is a card carrying the dormant-directory provider select — a bare-mounted `llm-pi-ai` offers its whole installed catalog before any route exists. **Add a custom provider** declares a route pi-ai does not ship; the create card asks for a unique **Provider ID**, an endpoint, a protocol, and at least one uniquely-identified model, because nothing can default those. **Fetch available models** asks `llm.discoverModels` about the endpoint the form shows, so adding a provider is one pass instead of save-then-return; the reply opens a picker rather than being written, and nothing is written until **Add selected**. A row is deletable only when the user layer alone carries it (removal restores the composition base), and its confirmation dialog names the provider.
+
+### First-run dialogs
+
+After the versioned notice step completes, the DeepSeek step projects first-run readiness from the same joined snapshot. ANY provider the user can already reach ends it without rendering; only a user with none is asked for the official DeepSeek key. Configure later completes only this coordinator pass, and an absent adapter, inactive route, failed join, read-only deployment, or unusable capability completes the step without rendering — Models remains the diagnostic surface.

+
+### Validation
+
+A typed API key is judged on its own field: after trimming, it must be non-empty and every character must be printable ASCII (`[\x21-\x7E]`), which is exactly what an HTTP header value can carry — the twin of `normalizeApiKey` in `@deepseek-ai/dsh-llm`, mirrored here because the source-plane split forbids importing it.

+
+The notice step owns its exact copy in `src/client/locales.ts` and its acknowledgement version in `src/onboarding-copy.ts`; on loopback it compares and writes `ui-onboarding.welcomeNoticeVersion` through the existing settings API, and only an explicit Continue records the current version. A non-loopback browser cannot use that Host-only namespace, so acknowledgement is process-local and the notice returns after reload.

 ## Known Limitations and Deferred Work
 
-- **Only the API key and curated fold fields are editable on the card** — the hand-written editor traded schema-generic field coverage for the mockup layout ([Agent Note](../../../.agents/notes/implemented/architecture/2026-07-30-web-config-plane.md)). Both families expose `baseURL` and model `id`/`name`/`contextWindow`/`maxTokens`; a hand-declared pi-ai route also exposes `displayName` and `api`. Retry policy, timeouts, DeepSeek model descriptions, and other advanced fields remain in `settings.yaml`; existing model fields the editor does not show are preserved. A profile schema without the conventional fields renders the hint alone, and the two curated layouts key on the `llm-deepseek`/`llm-pi-ai` namespaces by name.
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define the editor's field coverage and the page's reach; they are current package constraints, not a settings roadmap.

 - **Credential cleanup is intentionally narrow** — deleting a row removes the configured, writable credential only when its reference is the exact `<ROUTE>_API_KEY` target this page derives. Custom references, environment credentials, and unidentifiable targets are retained because the row cannot prove ownership of them.
 - **Only pi-ai routes can be hand-declared** — the custom-provider card writes into `llm-pi-ai`, the one namespace whose profiles describe a whole provider. A `llm-deepseek` route is a composition fact, not something this page can create.
 - **Interrogation covers OpenAI-compatible endpoints** — the adapter reads only that model-list response format, so a gateway speaking another protocol reports that it cannot be asked and its models are entered by hand.
 - **Undeclared live routes render nowhere** — a route registered without a configurable-provider declaration has no settings address; it stays visible in pickers but not on this page's rows.

-模型设置与产品引导插件。同一个 client Cordis 插件会注册 Models 页面和两个有序的首次使用弹窗：版本化内测声明，以及按条件显示的 DeepSeek 官方凭据步骤。两个步骤共用同一套弹窗组件，并继续由 `settings.onboarding` 排序。Models 平面把三个协议领域汇聚为一个共享快照：`llm.providers`（可配置提供方目录，含每条路由的存活／休眠状态）、`settings.describe`（序列化 schema、分层脱敏值、secret slot）与 `credentials.describe`（不含值的 configured/source/writable 徽标）；页面据此渲染提供方行，一次只展开一张编辑卡片，且不把路由存活状态呈现为提供方状态。
+## 概述
 
-Host 公布 `subagent-model-selection` settings namespace 时，Models 还会在提供方行上方渲染本地化开关。它默认关闭，只通过 `settings.update` 携带 namespace revision 写入 `{ enabled }`。Host 会在组合新的顶层 Session 时读取它；修改设置不会重新配置运行中的 Session，而子 Session 会继承父级已记录的决定。
+`dsh-client-ui-settings-models` 是 dsh Web 客户端的 Models 设置页面：用户可以配置 API 密钥（以只写方式存入 profile 的凭据引用之下）、编辑每个提供方的模型列表，并手工声明自定义 pi-ai 路由；页面以提供方行展示，一次只展开一张编辑卡片。该页面把提供方目录、设置文档与凭据描述合并为一个共享快照，因此行的状态在三个方面始终一致。它还会带首次运行的用户走两个有序弹窗——版本化内测声明，以及按条件显示的官方 DeepSeek 凭据步骤。
 
-行是*已配置*的提供方（其 profile 在所属 namespace 中解析得出）；其配置键未在任何位置配置的整分节提供方会渲染为其展开的设置卡片而非一行，但仅限首次运行姿态——即尚无任何提供方已注册且备齐其 profile 所指名的凭据——且仅持续到用户关闭该卡片为止，此后它就是一行带缺失密钥点的普通行。每一类卡片各自持有自己的展开状态，因此关掉其中一张绝不会丢弃另一张里的草稿。「新增」流程则是一张承载休眠目录提供方选择框的卡片——裸挂载的 `llm-pi-ai` 在任何路由存在之前就能提供其完整的已安装 catalog。pi-ai 卡片还会编辑该路由的**模型列表**，并可查询提供方所提供的模型。只有确认引用的凭据已配置时，行才会以绿色实心点标示 API 密钥状态；只有确认具名引用缺失时，才会以红色实心点标示。无引用的提供方原生认证以及无法取得凭据补充信息时都不显示状态点。编辑器是每个适配器家族各一张的手写卡片：主字段是单独一个 **API 密钥**输入框——页面从不询问环境变量名；键入的密钥经 `credentials.set` 以**只写**方式存入 profile 的引用之下，profile 没有引用时便派生 `<ROUTE>_API_KEY`，pi-ai profile 会把这次派生记录为 `apiKeyEnv`，因此 `settings.yaml` 从不携带密钥值。为新的 pi-ai 提供方留空密钥会保存一个不带引用的 profile，因此能保留提供方原生认证，例如 Bedrock 凭据链或 Vertex ADC。「应用」成功后会发出本地无障碍状态消息，且绝不回显任何机密内容。收起的「自定义设置」折叠区承载精选的额外字段——两个家族都有 `baseURL`（deepseek 的占位符显示公共端点）、各适配器自己的模型目录，以及适配器未提供的那类 pi-ai 路由的**显示名称**与 **API 协议**。这两个字段是手工声明路由为自己命名的东西：创建卡片之所以索要它们，正因为没有东西能为它们兜底，因此编辑器也够得着这两个，而不是把它们留给 `settings.yaml`。清空名称即取消设置，路由退回自己的 id——占位符显示的就是它；协议没有这样的兜底。内置目录路由两个都不给：它的名称由目录条目兜底，它的每个模型各自带着自己的协议，路由级协议只可能把它们全部覆盖掉。Provider ID 保持固定：它是 settings 的键、是其他每个 namespace 与每一条已记录会话引用的名字，也是页面读不回、因而搬不走的凭据引用词干。推理等级刻意**不在**其中：它是按模型的能力，而同一提供方下各模型接受的档位并不一致，因此提供方级的控件只可能被设成其中一些模型会拒绝的值——那会连支持该档位的模型也一并隐藏。输入框的模型选择器为每个模型提供它自己的档位，在那里切换会把提供方、模型、推理等级一并记为下一个会话的默认值。profile 字段仍留在 `settings.yaml`，供清楚自己路由的部署使用。每条 DeepSeek 模型行可编辑 `id`、可选的显示名称 `name` 与可选的 `contextWindow`/`maxTokens`；精选集合以外的现有字段会在编辑后保留，其余每个 profile 字段仍归 `settings.yaml` 所有。只有当某行仅由用户层承载时它才可删除（删除会还原组合 base），其本地化确认对话框会在标题、说明和最终操作中点名该提供方。当目录条目表明拥有该路由的适配器在这个键下什么都没有时，该行会带上 **自定义** 标签。标签只跟随这个答案：存了 profile 并不使一条路由成为自定义——收窄一个内置提供方的模型同样会存下 profile——而什么都不回答的适配器，其路由保持无标签，不会被当成内置。
+## 目录
 
-声明步骤在 `src/client/locales.ts` 中持有完整文案，并在 `src/onboarding-copy.ts` 中持有确认版本。回环访问会通过既有 settings API 比较并写入 `ui-onboarding.welcomeNoticeVersion`；只有明确点击「继续」才会记录当前版本。非回环浏览器无法使用这项仅限 Host 的 namespace，因此确认仅在当前进程有效，重载后声明会再次出现。

-声明完成后，DeepSeek 步骤会从同一个 Models 联接快照得出首次运行就绪状态。只要用户已经能触达**任何**一个提供方，它就直接完成而不渲染——已注册且其具名凭据引用已存储的路由（包括来自启动环境且只读的凭据），或 profile 根本不指名引用、因而走原生认证的路由。只有二者皆无的用户才会被要求填写 DeepSeek 官方密钥。适配器已挂载且活跃、引用可写但尚未配置时，既有 `ProviderEditor` 会以仅凭据模式渲染在共用引导弹窗中；`credentials.set` 仍是唯一的 secret 写入，且不会改变提供方设置。「稍后配置」只完成协调器当前这一轮。适配器缺失、路由不活跃、联接失败、部署只读或设置／凭据能力不可用时，该步骤不渲染并直接完成；Models 页仍是诊断界面。
+-----
 
-每一次编辑都以 `settings.mutate` 的路径 op 落到已存分节上——每个变更字段一条 set、每个清空字段一条 unset、删除提供方行则是单独一条 unset。页面自始至终只持有**脱敏后**的 descriptor，因此它只修改自己看得见的字段，而不重建分节。DeepSeek 的 `models` 是一个按值整体替换的数组：编辑器会显示继承而来的生效模型行，直到第一次模型编辑将完整数组具化到用户层；重置则会取消该覆盖。每个模型行承载模型 ID 与显示名称，其上下文窗口与最大输出 token 数则收在该行自己的折叠区里，使用与 pi-ai 提供方表单相同的字段。两项容量都按数值键入，可带十进制的 `K` 或 `M` 后缀（`256K`、`1M`；`1M` 即 1000K），存储为纯数值，回显时写成能够往返的最短形式。空 ID、重复 ID、显式填写的空名称，以及无法读取、非正数或非整数的容量都会在写入前失败。键入的 API 密钥同样在它自己的字段上被判定：trim 之后必须非空，且每个字符都是可打印 ASCII（`[\x21-\x7E]`）——这正是 HTTP 标头值所能承载的范围，是 `@deepseek-ai/dsh-llm` 中 `normalizeApiKey` 的孪生体，因源码平面分割禁止直接引入而在此镜像。与整行粘贴的 `NAME=value` 环境变量匹配或首尾成对引号包裹的值，会以同一条格式失败被拒绝；这项粘贴行检查只在浏览器中运行，因为 resolver 中的一次误判会连带让环境变量这条路也拒绝该密钥。只含空白的输入框会失败而不是被静默丢弃；留空则完全不是失败：在编辑卡片上意味着保持已存储的密钥，在新建卡片上则意味着以其他方式鉴权。被拒绝的密钥会同时拦截写入与端点探测，因此页面不会白花一次往返去换取字段上已经写明的答案。每次 settings 写入都携带卡片当前的 `revision`，因此来自另一个标签页或对 `settings.yaml` 的外部编辑所产生的并发写入会以 `settings-conflict` 被拒绝；settings 提交成功后，卡片会在存储凭据前采用响应返回的脱敏用户子树与 revision，因此凭据阶段失败时，重试只会重复该阶段。删除操作只会在 profile 指向页面派生的 `<ROUTE>_API_KEY` 目标时清除已配置且可写的凭据，随后取消设置 profile；两项操作都具备幂等性，部分失败会停留在点名目标的确认对话框中供重试。环境凭据、自定义引用和无法识别目标的凭据保持不变。页面加载完成后会直接订阅转发的 owner 事件 `settings/document-updated`、`credentials/reference-updated`、`llm/adapters-updated`，以及本地 `connection/reset`，因此外部的 `settings.yaml` 编辑、第二个标签页或 settings 新生的路由都无需轮询即可收敛。
+<a id="use-this-package"></a>
+## 使用本包
 
-## 模型列表与端点询问
+从设置导航打开 Models 页面，即可看到每个已配置的提供方都有一行。其配置键未在任何位置配置的整分节提供方会渲染为其展开的设置卡片而非一行，但仅限首次运行姿态，且仅持续到用户关闭该卡片为止。每一类卡片各自持有自己的展开状态，因此关掉其中一张绝不会丢弃另一张里的草稿。
 
-pi-ai profile 的 `models` 列表就在卡片上编辑：一行一个模型，行上显示 id 与显示名称，上下文窗口与输出上限收在该行的展开区内，右侧是两个无文字的操作——展开与删除。空列表意味着「使用该路由的内置 catalog」，因此每一行都只会被刻意添加；清空容量会丢弃它，而不是存入一个 schema 会拒绝的值，配置留空的部分由适配器的路由级回退值定尺寸——留空的容量以这些回退值的量级作为占位符，那只是提示而非镜像：该字段按 1000 计 `K`，且部署可以覆盖这些回退值。不是正整数的容量根本不会被存下。
+### API 密钥
 
-**获取可用模型**会针对表单**当前显示**的端点调用 `llm.discoverModels`，包括已修改但尚未保存的 API 地址和已键入但尚未存储的密钥，因此新增一个提供方是一趟走完，而不是「先保存再回来」。回复会打开一个选择框而不是直接写入：已配置过的候选默认不勾选，因此采纳一次选择绝不会覆盖用户已更正的容量。**全选**／**取消全选**只会改变选择框当前的勾选状态；点击**添加所选**之前不会写入任何内容。无法被询问的提供方只是绕路而非死路——适配器自己的消息会显示在各行旁边，而这些行仍可手工编辑。
+编辑卡片上的主字段是单独一个 **API 密钥**输入框——页面从不询问环境变量名。键入的密钥经 `credentials.set` 以**只写**方式存入 profile 的引用之下，profile 没有引用时便派生 `<ROUTE>_API_KEY`，pi-ai profile 会把这次派生记录为 `apiKeyEnv`，因此 `settings.yaml` 从不携带密钥值。为新的 pi-ai 提供方留空密钥会保存一个不带引用的 profile，从而保留提供方原生认证（例如 Bedrock 凭据链或 Vertex ADC）。只有确认引用的凭据已配置时，行才会以绿色实心点标示 API 密钥状态；只有确认具名引用缺失时，才会以红色实心点标示。「应用」成功后会发出本地无障碍状态消息，且绝不回显任何机密内容。
 
-**添加自定义提供方**用来声明 pi-ai 未提供的路由。它是独立的一张卡片而非在编辑器上加字段，因为路由 id 正是在这里被*选定*的，而在选定之前 settings 地址并不存在：一次 `settings.mutate` 在 `providers.<route>` 上设置整个 profile，密钥则经 `credentials.set` 单独传递，使用与既有提供方相同的 `<ROUTE>_API_KEY` 派生。手工声明的路由无法默认的东西会门控创建按钮——唯一的 **Provider ID**、端点、协议，以及至少一个标识唯一的模型——因此失败会在用户仍看着该字段时点名它。该 id 必须以小写字母开头，因为它同时是派生凭据引用的词干，而引用是 POSIX shell 标识符：数字开头的 id 否则会通过这张卡片的每一项检查，然后在凭据 seam 上抛出原始正则表达式错误。容量不参与门控：端点只按 id 描述的模型（这正是多数列表返回的形态）由适配器的回退值定尺寸。协议选项读自该 namespace 自己的 schema，而非某个协议字段或常量，因此它们不会与适配器实际接受的集合发生漂移。只有键入了密钥，这张卡片才记录约定的 `apiKeyEnv` 引用，与编辑器同一条规则，因此一条为提供方原生认证声明的路由不会一出生就指向一个永远不会被设置的引用。当 profile 写入成功而密钥写入失败时，提供方已经存在：卡片会把描述它的字段定住，只重试凭据——再跑一次 profile 写入会带着刚被自己这次写入取代的 revision，宿主将以 `settings-conflict` 应答，密钥就再也无法从这里存下——并且即使用户随后取消，也照实报告提供方已创建。
+### 编辑提供方
 
+收起的「自定义设置」折叠区承载精选的额外字段：两个家族都有 `baseURL`（deepseek 的占位符显示公共端点）、各适配器自己的模型目录，以及适配器未提供的 pi-ai 路由的**显示名称**与 **API 协议**。Provider ID 保持固定：它是 settings 的键、其他每个 namespace 与每一条已记录会话引用的名字，也是页面读不回、因而搬不走的凭据引用词干。推理等级刻意不在可编辑字段之列：它是按模型的能力，提供方级的控件只可能被设成某些模型会拒绝的值。每个 DeepSeek 行编辑 `id`、可选显示 `name` 与可选 `contextWindow`/`maxTokens`；该精选集之外的现有字段在编辑后仍会保留。
+
+### 子代理模型选择
+
+当宿主提供 `subagent-model-selection` 设置 namespace 时，Models 会在提供方行上方显示一个本地化开关。该开关默认关闭，并通过 `settings.update` 携带 namespace revision、只写入 `{ enabled }`。宿主在组合新的顶层 Session 时读取此值，因此更改它不会重新配置正在运行的 Session。子 Session 会继承其父级已记录的决定。
+
+### 新增与删除提供方
+
+「新增」流程是一张承载休眠目录提供方选择框的卡片——裸挂载的 `llm-pi-ai` 在任何路由存在之前就能提供其完整的已安装 catalog。**添加自定义提供方**声明一条 pi-ai 不提供的路由；创建卡片会索要唯一的 **Provider ID**、端点、协议与至少一个可唯一识别的模型，因为没有东西能为它们兜底。**获取可用模型**就表单显示的端点询问 `llm.discoverModels`，因此新增提供方一次即可完成，而非先保存再返回；回复打开的是选择器而非直接写入，只有点击**添加所选**才会写入。只有用户层单独携带某行时，该行才可删除（删除会恢复组合基线），其确认对话框会指名该提供方。
+
+### 首次运行弹窗
+
+版本化声明步骤完成后，DeepSeek 步骤从同一份合并快照投影首次运行就绪状态。用户已经能够到达的**任何**提供方都会直接结束该步骤、不做渲染；只有没有任何提供方的用户才会被询问官方 DeepSeek 密钥。「稍后配置」只完成这次协调器遍历；适配器缺失、路由不活动、合并失败、只读部署或能力不可用时，该步骤不渲染即完成——Models 仍是诊断界面。

+<details>
+<summary>实现细节——点击展开</summary>
+
+页面只持有脱敏后的描述符，从不持有完整设置分区：因此每次编辑都以 `settings.mutate` 路径操作落到已存分区上——每个改动字段一次 set、每个清除字段一次 unset、删除提供方行则一次 unset。
+
+### 校验
+
+键入的 API 密钥按其自身字段判定：去除首尾空白后必须非空，且每个字符都必须是可打印 ASCII（`[\x21-\x7E]`），这正是 HTTP 头值能够携带的字符集——与 `@deepseek-ai/dsh-llm` 中的 `normalizeApiKey` 互为镜像，此处复刻是因为源平面拆分禁止导入它。与粘贴的 `NAME=value` 环境行一致或包裹在匹配引号内的值，会作为同样的格式失败被拒绝。空 id、重复 id、空显式名称以及不可读、非正数或小数的容量都会在任何写入之前失败。DeepSeek 的 `models` 是一个按值整体替换的数组：编辑器先显示继承的有效行，直到第一次模型编辑把完整数组物化进用户层，重置则取消该覆盖。
+
+### 并发与凭据
+
+每次 settings 写入都携带卡片当前的 `revision`，因此来自另一个标签页或外部 `settings.yaml` 编辑的并发写入会以 `settings-conflict` 被拒绝。settings 提交后，卡片会在存储凭据前采纳返回的脱敏用户子树与 revision，因此失败的凭据阶段只重试该阶段。删除只会在 profile 指名本页派生的 `<ROUTE>_API_KEY` 目标时移除已配置且可写的凭据，然后 unset 该 profile；两个操作都幂等。加载完成后，页面订阅转发的 `settings/document-updated`、`credentials/reference-updated` 与 `llm/adapters-updated` 属主事件，以及本地 `connection/reset`，因此外部编辑无需轮询即可收敛。
+
+### 引导协调器
+
+声明步骤在 `src/client/locales.ts` 中持有精确文案，并在 `src/onboarding-copy.ts` 中持有确认版本；回环时它通过既有 settings API 比较并写入 `ui-onboarding.welcomeNoticeVersion`，且只有显式点击「继续」才会记录当前版本。非回环浏览器无法使用这个仅限宿主的 namespace，因此确认只保留在进程内，刷新后声明会再次出现。DeepSeek 步骤在共享引导模态框内以仅凭据模式渲染既有 `ProviderEditor`；`credentials.set` 仍是唯一的机密写入，且不改变任何提供方设置。

 # @deepseek-ai/dsh-client-ui-settings-plugin-inventory
 
 English | [中文](README.zh.md)
 
-Read-only **Plugin list** tab for Web Settings. The browser plugin registers one localized `settings.plugins.tab` contribution with id `all`; the Plugins section owns the navigation entry and tab chrome. It performs no Remote read during plugin activation. Selecting the tab for the first time mounts it and lazily calls `ctx.remote.pluginInventory.list()` through [`api-remotes`](../../api/remotes/README.md).
+## Summary
 
-The tab renders a searchable two-column catalog of compact disclosure cards. Each collapsed card uses the short module name as its title and a small effective-enablement tag; enabled entries also show a colored root-fiber status dot. Expanding one card reveals its Loader-tree entry id without a redundant field label, followed by the effective configuration and, for enabled entries, Cordis status. Disabled entries omit the redundant unmounted runtime state. The entry id remains the React key, disclosure identity, detail value, and an additional search target; it is never classified by string shape. Loading, empty, no-match, and generic failure states stay local to the mounted component, and a failed read can be retried without exposing transport details. The registration uses `ctx.slots.inject()`, so it follows late tab declaration, redeclaration, locale changes, and teardown without importing the section owner.
+`dsh-client-ui-settings-plugin-inventory` contributes the read-only **Plugin list** tab to the Web Settings Plugins section. The tab lazily calls `ctx.remote.pluginInventory.list()` the first time it is selected and renders a searchable two-column catalog of compact disclosure cards: each collapsed card shows the short module name, an effective-enablement tag, and (for enabled entries) a colored root-fiber status dot; expanding a card reveals the Loader-tree entry id, effective configuration, and Cordis status.

+## Use this package
+
+Open the Plugins section in Settings and select the **Plugin list** tab to inspect the Host's plugin inventory. The tab reads no Remote during plugin activation — selecting it for the first time mounts the component and lazily calls `ctx.remote.pluginInventory.list()` through `api-remotes`.
+
+### Reading a card
+
+Each collapsed card uses the short module name as its title and a small effective-enablement tag; enabled entries also show a colored root-fiber status dot. Expanding one card reveals its Loader-tree entry id, followed by the effective configuration and, for enabled entries, Cordis status; disabled entries omit the redundant unmounted runtime state. Search filters the catalog by name and entry id.

+### Retrying a failed read
+
+A failed read renders a generic failure state inside the tab; retrying re-runs the lazy `list()` call without exposing transport details.

+
+
+These limits define the freshness and reach of the inventory view; they are current package constraints.
+
 - **One snapshot per Settings mount or retry** — the tab does not subscribe to Loader changes or automatically refetch after reconnect; switching tabs preserves the current snapshot, while reopening Settings obtains a new one.
 - **Read-only Loader view** — local search does not add provenance, current-browser activation diagnosis, grouping by source, or plugin mutation controls.

-The **Plugins** settings section and its **Plugin configuration** tab. The section owns the heading and compact tab chrome; feature plugins contribute pages through `settings.plugins.tab`. This package's own tab shows one expandable card per Host plugin whose configuration a user owns. A card shows the plugin's name and what it governs; expanding it in place reveals hand-written controls bound to that plugin's settings namespace, each field marking whether the user overrode it and offering a reset back to the value the deployment composed.
+## Summary
 
-## What appears here
+`dsh-client-ui-settings-plugins` is the **Plugins** settings section of the dsh web client: users edit host-plane plugin configuration on its **Plugin configuration** tab, and feature plugins contribute their own pages through `settings.plugins.tab`. This package's own tab shows one expandable card per Host plugin whose configuration a user owns: a card shows the plugin's name and what it governs, and expanding it reveals hand-written controls bound to that plugin's settings namespace, each field marking whether the user overrode it and offering a reset back to the value the deployment composed. Cards stage edits locally and write only on save, with every write fenced by the namespace revision the form read.
 
-The configurable tab reads which settings namespaces the Host serves and dispatches one slot key per namespace, so what renders is the intersection of two ledgers: the namespaces a live Host plugin registered, and the cards registered under those keys. A served namespace no card claims renders nothing — another surface owns it, or this deployment ships no browser half for it — and a card whose namespace this deployment does not serve is never dispatched, so an uncomposed plugin leaves no trace and does not hold the tab back from its empty line. The empty line waits for the Host's first answer, so an unanswered read never reads as "this deployment configures no plugin". Cards appear in the order they registered, which is stable for the cards one package installs together and not stable across plugins: apply order between packages is unconstrained.
+## Table of Contents
 
-The cards this package ships cover the shell executor (`bash`), the agent loop's tool-call parallelism (`agent-loop`), and the DeepSeek search provider (`web-search-deepseek`).

-## Extension point
+-----
 
-The section declares `settings.plugins.tab`, a root list slot whose labels become ordered tabs. It keeps a tab mounted after its first selection, so local drafts and read-only snapshots survive tab switches. The package registers its own `configurable` contribution, which declares the nested `settings.plugin.item` slot — keyed on the settings namespace a card edits. A plugin that ships a browser half registers its own card under its own namespace and owns every part of it: chrome, controls, and copy. Keying on the namespace is what lets a plugin distributed outside this repository appear here — it registers the namespace on the Host and the card in the browser, and the tab pairs the two without learning what the namespace means. Tabs follow the contribution's `order`; cards follow registration order.
+<a id="use-this-package"></a>
+## Use this package
 
-## Writes
+Open the Plugins section in Settings and select the **Plugin configuration** tab to edit the host-plane plugins this deployment composes. The cards this package ships cover the shell executor (`bash`), the agent loop's tool-call parallelism (`agent-loop`), and the DeepSeek search provider (`web-search-deepseek`).
 
-A card stages what the user types and writes it only when they save. Each control renders staged text, so what is on screen is exactly what a save would store; **Discard** drops the drafts, and a card holding unsaved edits says so on its header even while collapsed. A reset stages the composed default rather than writing immediately, and a draft the field does not accept blocks the save instead of being dropped.
+### What appears here
 
-Saving writes each staged field through the client settings scope, which fences every write with the namespace revision it read, so a form that has drifted from the document is refused rather than overwriting a concurrent change. The Host is the only authority on whether a value was accepted — its validators own the constraints no schema can express — so the card reads the section back afterwards and reports a save that did not land, keeping those drafts for the user to correct.
+The tab reads which settings namespaces the Host serves and dispatches one slot key per namespace, so what renders is the intersection of two ledgers: the namespaces a live Host plugin registered, and the cards registered under those keys. A served namespace no card claims renders nothing, and a card whose namespace this deployment does not serve is never dispatched. The empty line waits for the Host's first answer, so an unanswered read never reads as "this deployment configures no plugin".
 
-A key can also be written from another surface — the Models page addresses the same reference — which changes no settings section, so the card re-reads on the forwarded `credentials/reference-updated` event for the reference it watches.
+### Editing and saving
 
-A field's presence in the raw user layer — not its value — is what marks it overridden; a reset clears that field so it re-inherits the composition layer. Secret-role fields never ride a response, so a key control starts blank, reports only whether one is configured, and writes through the credentials domain rather than the settings section; a blank draft writes nothing and keeps the stored key.

 ## Known Limitations and Deferred Work
 
-- **Only host-plane plugins appear** — a plugin an agent preset mounts carries its configuration inline in that preset's `agent.cordis.yml` and cannot register a settings namespace at all (a second session mounting the same preset would fail on a duplicate registration), so this section lists nothing for it. Editing those values remains the preset editor's job.
-- **A card still needs a browser bundle** — the browser half must be a `dsh.client` package built in the client module system's lazy-CJS factory format, and the `clientBundle` preset that emits it lives in `packages/client/tsdown.client.ts` rather than a published package, so a plugin outside this repository has to reproduce that build itself. The bundle-purity gate also forbids importing this package's card chrome or form model as values, so such a card owns its own staging and revision fencing.
+<a id="known-limitations-and-deferred-work"></a>
+

+These limits define which plugins appear and how fresh the list is; they are current package constraints.

-- **只有宿主平面的插件会出现**——由 agent preset 挂载的插件把配置内联在该 preset 的 `agent.cordis.yml` 中，且根本无法注册 settings 命名空间（同一 preset 挂载第二个会话时会因重复注册而失败），因此本分区不会列出它。编辑那些值仍是 preset 编辑器的职责。
-- **卡片仍然需要一份浏览器 bundle**——浏览器半侧必须是按客户端模块系统的 lazy-CJS factory 格式构建的 `dsh.client` 包，而产出它的 `clientBundle` 预设位于 `packages/client/tsdown.client.ts`，并非已发布的包，因此本仓库之外的插件得自行复刻该构建。bundle 纯净度门禁同时禁止以值的形式导入本包的卡片外观与表单模型，所以这样的卡片要自行拥有暂存与 revision 设栅。
-- **被服务的命名空间只在两种信号上重读**——协议通告的是 settings 文档提交与连接重置，而非注册行为，因此在标签页读取之后才被其拥有方注册的命名空间，要等下一次文档提交或重连才会加入列表。
-- **shell 卡片跟随被组装的执行器**——POSIX 与 PowerShell 两个执行器家族共用 `bash` 命名空间，因为一个宿主只组装其中之一，所以被服务的 schema 随平台不同（PowerShell 多出 `pwshPath`），尽管卡片在两者下编辑的都是同样两个字段；而两者都不组装的部署不会显示这张卡片。

+- **被服务的命名空间只在两种信号上重读**：协议通告的是 settings 文档提交与连接重置，而非注册行为，因此在标签页读取之后才被其拥有方注册的命名空间，要等下一次文档提交或重连才会加入列表。
+- **shell 卡片跟随被组装的执行器**：POSIX 与 PowerShell 两个执行器家族共用 `bash` 命名空间，因为一个宿主只组装其中之一，所以被服务的 schema 随平台不同（PowerShell 多出 `pwshPath`），尽管卡片在两者下编辑的都是同样两个字段。

 # @deepseek-ai/dsh-client-ui-settings
 
 English | [中文](README.zh.md)
 
-The settings domain's base layer, with no presentation of its own. It provides `ctx.settingsScope`, the Host transport every preference row binds its durable namespace section through; `ctx.settingsSchema`, the synchronous schema-rehydration, validation, and immutable path-editing service used by settings plugins; and the settings slot types registrants fill: `settings.trigger` / `settings.header` / `settings.close` (chrome content), `settings.action` (ordered content-header actions), `settings.section` (one page per feature), `settings.plugins.tab` (feature-owned pages inside the Plugins section), and `settings.onboarding` (ordered feature-owned pages). It depends on no `ui-*` presentation package, so any feature that owns a preference can reach it; the settings SHELL — the `sidebar.settings` occupant, its navigation, and the chrome — lives in ui-settings-general, because a shell dependency on ui-sidebar would close a reference graph cycle through ui-layout and ui-theme. The shell's own contract types live beside the shell for the same reason.
+## Summary
 
-The plugin injects `connection` and `remote` and owns the one `settings.describe` reader in the browser: a shared mirror holding the whole answer, refreshed on every forwarded `settings/document-updated` event and on `connection/reset` (the first connection included — that read closes the window where a commit lands between the eager read and the SSE subscription). Schema operations are synchronous and live on the `settingsSchema` service. `ctx.settingsScope.bind(spec)` returns a per-namespace scope DERIVED from the mirror on the CALLER's context — the scope's disposer belongs to the calling fiber, binding adds no wire read, a row's activation never blocks on the settings transport, and every derived surface shows the same document revision at any moment. Cross-namespace surfaces (schema introspection, the served-namespace directory, `hasDocument`) read the same mirror through `ctx.settingsScope.describe()`, a read/fold face (`getSnapshot`/`subscribe`/`ensure`, plus `acceptView` folding a write answer in). The scope snapshot carries the resolved section, composition `base`, raw `user`, revision, writability, and host/memory mode; a field is overridden when it is present in `user`, even when its value equals `base`, and `unset` clears that override. Writes stay per-scope: one field path fenced by the namespace revision as `expectedRevision`; a committed write folds its answer back into the mirror with no re-read, a rejected or failed latest write triggers one mirror recovery read, and a superseded one leaves recovery to its successor. Without a `decode` in the spec, a section that is not a plain object, fails its rehydrated schema, or carries a schema envelope this client cannot rehydrate publishes no value at all, so a row renders its own absent state instead of a half-decoded one. The cold-boot read count is pinned by `apps/web/tests/startup-rpc-budget.e2e.ts`; a new direct `settings.describe` caller in client code is a regression against it.
+`dsh-client-ui-settings` is the base every preference surface in the dsh web client builds on: a feature plugin binds a namespace and stores or edits its preference rows in the Host settings document without re-implementing transport or schema handling. `ctx.settingsScope` derives a per-namespace scope from the shared document mirror with revision fencing, so a concurrent write from another surface is refused instead of silently overwritten; `ctx.settingsSchema` rehydrates and validates schemas and edits immutable paths synchronously. It declares the slot types settings surfaces fill — `settings.trigger`/`settings.header`/`settings.close` (chrome), `settings.action` (ordered header actions), `settings.section` (one page per feature), `settings.plugins.tab`, and `settings.onboarding` — and renders nothing itself. Because it depends on no `ui-*` presentation package, any feature that owns a preference can reach it; the settings shell itself lives in ui-settings-general.

+## Use this package
+
+Feature plugins use this package to store and edit their preferences without re-implementing transport or schema handling. Mount it once per composition; it injects `connection` and `remote` and owns the single `settings.describe` reader in the browser.
+
+### Binding a namespace
+
+A feature calls `ctx.settingsScope.bind(spec)` with a per-namespace spec and gets a scope derived from the shared document mirror. The scope snapshot carries the resolved section, composition `base`, raw `user`, revision, writability, and host/memory mode; a field is overridden when it is present in `user`, even when its value equals `base`, and `unset` clears that override. Writes go through the scope: one field path fenced by the namespace revision as `expectedRevision`, so a concurrent write from another surface is refused instead of silently overwritten.
+
+### Filling the settings slots
+
+A settings surface registers into the slot types this package declares. The shell (`sidebar.settings` occupant, navigation, chrome) lives in ui-settings-general; feature pages register `settings.section` contributions; the Plugins section hosts `settings.plugins.tab` pages; onboarding steps register `settings.onboarding`. Cross-namespace surfaces (schema introspection, the served-namespace directory, `hasDocument`) read the same mirror through `ctx.settingsScope.describe()`.
+
+### Observable success and failures
+
+A bound scope reflects the current document revision immediately; a committed write folds its answer back into the mirror with no re-read. A rejected or failed latest write triggers one mirror recovery read; a superseded write leaves recovery to its successor. Without a `decode` in the spec, a section that is not a plain object or fails schema rehydration publishes no value, so a row renders its own absent state instead of a half-decoded one.
+

+
+<a id="understand-the-implementation"></a>
+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+The package realizes one ownership rule: the browser keeps one shared mirror of the settings document, and every derived surface reads that single source, so any moment in time shows the same document revision.
+
+### The describe mirror
+
+The plugin injects `connection` and `remote` and owns the one `settings.describe` reader in the browser: a shared mirror refreshed on every forwarded `settings/document-updated` event and on `connection/reset` (the first connection included, closing the window where a commit lands between the eager read and the SSE subscription). Cross-namespace surfaces read it through `ctx.settingsScope.describe()`, a read/fold face (`getSnapshot`/`subscribe`/`ensure`, plus `acceptView` folding a write answer in).
+
+### Scope derivation
+
+`ctx.settingsScope.bind(spec)` returns a per-namespace scope derived from the mirror on the caller's context: the scope's disposer belongs to the calling fiber, binding adds no wire read, and a row's activation never blocks on the settings transport. Writes stay per-scope with the namespace revision as `expectedRevision`; a committed write folds its answer in, a rejected or failed latest write triggers one recovery read, and a superseded one leaves recovery to its successor. The cold-boot read count is pinned by `../../../apps/web/tests/startup-rpc-budget.e2e.ts`; a new direct `settings.describe` caller in client code is a regression against it.
+
+### Schema service
+
+`ctx.settingsSchema` performs synchronous schema rehydration, validation, and immutable path editing for settings plugins. Without a `decode` in the spec, a section that is not a plain object, fails its rehydrated schema, or carries a schema envelope this client cannot rehydrate publishes no value at all.

 - **Non-loopback pages get no durable settings** — this Client keeps Host persistence disabled there, so a scope starts `unavailable` and never crosses the wire; every row it backs is inert even though Connection authentication covers the API.

 # @deepseek-ai/dsh-client-ui-settings
 
 [English](README.md) | 中文
 
-设置领域的底座，本身不含任何呈现内容。它提供 `ctx.settingsScope`——每个偏好设置行绑定自己那份持久化命名空间分区所用的宿主传输层；`ctx.settingsSchema`——设置插件使用的同步 schema 重建、校验与不可变路径编辑服务；并声明由注册方填充的设置 slot 类型：`settings.trigger`／`settings.header`／`settings.close`（界面框架内容）、`settings.action`（内容标题栏中的有序操作）、`settings.section`（每项功能一页）、`settings.plugins.tab`（“插件”分区内由各功能持有的页面）和 `settings.onboarding`（由各功能持有的有序页面）。它不依赖任何 `ui-*` 呈现包，因此任何持有偏好设置的功能都能够到它；设置**外壳**——`sidebar.settings` 占位方、它的导航与界面框架——位于 ui-settings-general，因为外壳一旦依赖 ui-sidebar，就会经 ui-layout 与 ui-theme 闭合出一条引用图环路。外壳自身的契约类型出于同一原因与外壳放在一起。
+## 概述
 
-该插件注入 `connection` 与 `remote`，并持有浏览器中唯一的 `settings.describe` 读取方：一面持有完整应答的共享镜像，在每次转发的 `settings/document-updated` 事件与 `connection/reset` 时刷新（首次连接也包含在内——这次读取关闭了「提交落在急切读取与 SSE 订阅之间、其失效通知丢失」的窗口）。schema 操作为同步调用，由 `settingsSchema` 服务承载。`ctx.settingsScope.bind(spec)` 在**调用方**的 context 上返回一个由镜像**派生**的按命名空间 scope——scope 的 disposer 归调用方 fiber 所有，绑定不新增任何线路读取，某一行的激活绝不会阻塞在设置传输层上，且任一时刻每个派生面看到的都是同一份文档 revision。跨命名空间的表面（schema 内省、已服务命名空间目录、`hasDocument`）通过 `ctx.settingsScope.describe()` 读同一面镜像，这是一个读取／折叠面（`getSnapshot`／`subscribe`／`ensure`，另有把写应答折入的 `acceptView`）。scope 快照携带解析后的分区、组合 `base`、原始 `user`、revision、可写性以及 host／内存模式；字段只要出现在 `user` 中即视为覆盖，即使其值与 `base` 相等，`unset` 会清除该覆盖。写入仍归各 scope：单一字段路径，以命名空间 revision 作为 `expectedRevision` 围栏；提交成功的写入将应答折回镜像、不再重读，被拒绝或失败的最新写入触发一次镜像恢复读取，被取代的写入则把恢复留给后继者。若 spec 未提供 `decode`，则分区不是普通对象、未通过其重建后的 schema 校验、或携带本客户端无法重建的 schema 信封时，一律不发布任何值，于是行渲染自己的缺失状态，而不是一份半解码的值。冷启动读取次数由 `apps/web/tests/startup-rpc-budget.e2e.ts` 钉住；客户端代码中新增直连 `settings.describe` 调用即是对它的回归。
+`dsh-client-ui-settings` 是 dsh Web 客户端每个偏好设置界面都依赖的底座：功能插件绑定一个命名空间，即可在宿主设置文档中存储或编辑自己的偏好设置行，而无需重新实现传输层或 schema 处理。`ctx.settingsScope` 从共享文档镜像派生按命名空间的 scope，并以 revision 设栅，因此来自另一界面的并发写入会被拒绝，而不是被静默覆盖；`ctx.settingsSchema` 同步重建并校验 schema、编辑不可变路径。它声明设置界面所填充的 slot 类型——`settings.trigger`/`settings.header`/`settings.close`（界面框架）、`settings.action`（有序标题栏操作）、`settings.section`（每项功能一页）、`settings.plugins.tab` 与 `settings.onboarding`——而自身不渲染任何内容。由于它不依赖任何 `ui-*` 呈现包，任何持有偏好设置的功能都能够到它；设置外壳本身位于 ui-settings-general。

+## 使用本包
+
+功能插件用本包存储与编辑自己的偏好设置，而无需重新实现传输层或 schema 处理。每个组合挂载一次即可；它注入 `connection` 与 `remote`，并持有浏览器中唯一的 `settings.describe` 读取方。
+
+### 绑定命名空间
+
+功能调用 `ctx.settingsScope.bind(spec)` 并传入按命名空间的 spec，得到一个由共享文档镜像派生的 scope。scope 快照携带解析后的分区、组合 `base`、原始 `user`、revision、可写性以及 host/内存模式；字段只要出现在 `user` 中即视为覆盖，即使其值与 `base` 相等，`unset` 会清除该覆盖。写入经 scope 进行：单一字段路径以命名空间 revision 作为 `expectedRevision` 围栏，因此来自另一界面的并发写入会被拒绝，而不是被静默覆盖。
+
+### 填充设置 slot
+
+设置界面会注册进本包声明的 slot 类型。外壳（`sidebar.settings` 占位方、导航、界面框架）位于 ui-settings-general；功能页面注册 `settings.section` 贡献；「插件」分区承载 `settings.plugins.tab` 页面；首次使用引导步骤注册 `settings.onboarding`。跨命名空间的表面（schema 内省、已服务命名空间目录、`hasDocument`）通过 `ctx.settingsScope.describe()` 读同一面镜像。
+
+### 可观察的成功与失败
+
+绑定后的 scope 会立即反映当前文档 revision；提交成功的写入把应答折回镜像、不再重读。被拒绝或失败的最新写入触发一次镜像恢复读取；被取代的写入把恢复留给后继者。若 spec 未提供 `decode`，则分区不是普通对象或未通过 schema 重建时一律不发布任何值，于是行渲染自己的缺失状态，而不是一份半解码的值。

+<summary>实现细节——点击展开</summary>
+
+本包实现一条归属规则：浏览器保留设置文档的一面共享镜像，每个派生表面都读这同一真源，因此任一时刻看到的都是同一份文档 revision。
+
+### Describe 镜像
+
+插件注入 `connection` 与 `remote`，并持有浏览器中唯一的 `settings.describe` 读取方：一面共享镜像，在每次转发的 `settings/document-updated` 事件与 `connection/reset` 时刷新（首次连接也包含在内，关闭「提交落在急切读取与 SSE 订阅之间」的窗口）。跨命名空间表面通过 `ctx.settingsScope.describe()` 读它，这是一个读取/折叠面（`getSnapshot`/`subscribe`/`ensure`，另有把写应答折入的 `acceptView`）。
+
+### Scope 派生
+
+`ctx.settingsScope.bind(spec)` 在调用方的 context 上返回一个由镜像派生的按命名空间 scope：scope 的 disposer 归调用方 fiber 所有，绑定不新增任何线路读取，某一行的激活绝不会阻塞在设置传输层上。写入仍归各 scope，以命名空间 revision 作为 `expectedRevision` 围栏；提交成功的写入把应答折回镜像，被拒绝或失败的最新写入触发一次恢复读取，被取代的写入把恢复留给后继者。冷启动读取次数由 `../../../apps/web/tests/startup-rpc-budget.e2e.ts` 钉住；客户端代码中新增直连 `settings.describe` 调用即是对它的回归。
+
+### Schema 服务
+
+`ctx.settingsSchema` 为设置插件执行同步 schema 重建、校验与不可变路径编辑。若 spec 未提供 `decode`，则分区不是普通对象、未通过其重建后的 schema 校验、或携带本客户端无法重建的 schema 信封时，一律不发布任何值。

+<a id="known-limitations-and-deferred-work"></a>
+
+
+这些限制说明设置传输层够不到的地方；它们是当前包约束。
 
 - **非 loopback 页面没有持久化设置**：本 Client 在那里禁用 Host 持久化，因此 scope 以 `unavailable` 起步且从不跨线路；尽管 Connection 认证覆盖 API，它支撑的每一行仍在那里无效。
 - **每次写入仅一个字段**：`set` 只发送单个 `set` op，因此需要同时改动两个字段的行没有事务可用，会发布两个 revision。

 # @deepseek-ai/dsh-client-ui-sidebar
 
 English | [中文](README.zh.md)
 
-Sidebar shell plugin: the brand row, New Session action, layout-owned collapse control, scroll-aware region seat, and bottom-pinned Settings seat. [ui-workspace](../ui-workspace/README.md) owns the Workspace and Session browser rendered into `sidebar.workspaces`; this package neither derives its rows nor owns its view preferences. Collapse into the layout-owned 56px rail remains presentation-local. Contract: the [slot system standard](../../../.agents/notes/implemented/architecture/2026-07-22-slot-type-chain-implementation.md).
+## Summary
 
-The expanded brand row renders `sidebar.brand.mark` and `sidebar.brand.name` as independent single slots, while the collapsed rail renders the same mark slot. Without occupants, the shell uses the fish mark and a localized local-build label. A complete build stacks below it a code badge assembled as `version[-commit][-dirty]` from `DSH_CLIENT_VERSION`, the optional 7-character `DSH_CLIENT_COMMIT_HASH`, and `DSH_CLIENT_GIT_DIRTY=true`; missing version metadata omits the badge. A deployment package can replace either value without replacing the New Session control or rail geometry; declaration-aware `slots.inject()` lets such a package activate before or after the sidebar.
+`dsh-client-ui-sidebar` is the sidebar shell of the dsh web client: users see the brand row, start new sessions, collapse into the layout-owned 56px rail, and reach Settings from the bottom-pinned seat, while the scroll-aware region seat hosts the Workspace and Session browser. The Workspace and Session browser rendered into `sidebar.workspaces` belongs to ui-workspace; this package neither derives its rows nor owns its view preferences. A deployment package can replace the brand mark or name without replacing the New Session control or the rail geometry, and New Session starts the runtime's page-local frontend Session Intent against the explicit, current, or most recently active Workspace. Collapse into the layout-owned 56px rail remains presentation-local.
 
-New Session starts the runtime's page-local frontend Session Intent. The runtime targets the explicit Workspace used by a scoped action, otherwise the current Session's Workspace, otherwise the most recently active Workspace; when none exists it clears into the blank New Session page. Workspace-specific controls and the shared picker belong to ui-workspace.
+## Table of Contents
 
-`SidebarRootComponentProps` composes the layout owner share, the global `useSessions` and `useWorkspaces` hooks, the declared brand, `sidebar.workspaces`, and `sidebar.settings` child slots, and injected `startSession` plus sidebar-toggle callbacks. There is no plugin store.

-During a live collapse, the shell holds the expanded content at its current width while it fades out for 150ms. The four upper controls—the shell toggle and New Session plus add and search rendered through `sidebar.workspaces`—then share one 150ms fade and 49px leftward translation into the 56px rail, ending with the layout's 300ms column slide; every 36px control box follows the same path to the rail's 10px left inset. The bottom-pinned `sidebar.settings` control shares the fade timing but has no horizontal translation. A page that starts collapsed renders the rail statically, and reduced-motion mode disables both transitions.
+-----
 
-Scrollbars in the column are a pointer affordance: the shell rebinds ui-theme's [scrollbar indirection](../ui-theme/README.md) to `transparent` whenever the pointer is outside it, and keeps the thumb drawn for 2s after the pointer leaves, so a list nobody is pointing at carries no bar. The reservation that keeps rows from moving belongs to the scrolling region ([ui-workspace](../ui-workspace/README.md)), so revealing a thumb never reflows.
+<a id="use-this-package"></a>
+## Use this package
 
-The foot is the `sidebar.settings` seat: the sidebar renders only the bottom-pinned layout slot and shares its column state (`wide`); ui-settings registers the trigger row and settings panel there.
+The sidebar is the navigation shell: users see the brand, start new sessions, collapse the rail, and reach Settings. Feature plugins fill its seats — ui-workspace fills `sidebar.workspaces`, ui-settings registers the trigger row and settings panel at `sidebar.settings`.
 
-The `/client` exports are the plugin body (`apply`/`inject`) plus the contract types only; SidebarRoot, the row components, and the tree derivation remain package-internal behind the slot registration.
+### Brand and New Session
 
+The expanded brand row renders `sidebar.brand.mark` and `sidebar.brand.name` as independent single slots; the collapsed rail renders the same mark slot. Without occupants, the shell uses the fish mark and a localized local-build label. A complete build stacks a code badge below the label as `version[-commit][-dirty]`, using `DSH_CLIENT_VERSION`, the optional 7-character `DSH_CLIENT_COMMIT_HASH`, and `DSH_CLIENT_GIT_DIRTY=true`; missing version metadata omits the badge. New Session targets the explicit Workspace used by a scoped action, otherwise the current Session's Workspace, otherwise the most recently active Workspace; when none exists it clears into the blank New Session page.
+
+### Collapse behavior
+
+During a live collapse, the expanded content fades out at its current width, the upper controls share one fade and leftward translation into the 56px rail, and the layout's column slide ends the motion. A page that starts collapsed renders the rail statically, and reduced-motion mode disables both transitions. The bottom-pinned `sidebar.settings` control shares the fade timing but has no horizontal translation.

+Scrollbars in the column are a pointer affordance: the shell rebinds the scrollbar indirection to `transparent` whenever the pointer is outside the column and keeps the thumb drawn for 2s after the pointer leaves, so a list nobody is pointing at carries no bar. The reservation that keeps rows from moving belongs to the scrolling region (ui-workspace), so revealing a thumb never reflows.

+The shell is pure composition: `SidebarRootComponentProps` composes the layout owner share, the global `useSessions` and `useWorkspaces` hooks, the declared brand, the `sidebar.workspaces` and `sidebar.settings` child slots, and injected `startSession` plus sidebar-toggle callbacks. There is no plugin store.
+
+### Slot discipline
+
+Declaration-aware `slots.inject()` lets a replacing package activate before or after the sidebar. The foot is the `sidebar.settings` seat: the sidebar renders only the bottom-pinned layout slot and shares its column state (`wide`). The `/client` exports are the plugin body (`apply`/`inject`) plus the contract types only; SidebarRoot, the row components, and the tree derivation remain package-internal behind the slot registration.

-侧边栏外壳插件：负责品牌行、New Session 操作、布局持有的折叠控件、可感知滚动的区域 seat，以及固定在底部的 Settings seat。[ui-workspace](../ui-workspace/README.zh.md) 持有渲染到 `sidebar.workspaces` 的 Workspace 与 Session 浏览器；本包既不派生其中的行，也不持有其视图偏好。折叠到布局拥有的 56px 轨道仍属于本地呈现行为。约定：[slot 系统标准](../../../.agents/notes/implemented/architecture/2026-07-22-slot-type-chain-implementation.zh.md)。
+## 概述
 
-展开的品牌行把 `sidebar.brand.mark` 与 `sidebar.brand.name` 渲染为两个独立的 single slot，收起轨道则渲染同一个 mark slot。没有占位者时，外壳使用鱼形标记和本地化的本地构建标签。完整构建会在标签下方显示代码徽标；该徽标由 `DSH_CLIENT_VERSION`、可选的 7 位 `DSH_CLIENT_COMMIT_HASH` 与 `DSH_CLIENT_GIT_DIRTY=true` 组装成 `version[-commit][-dirty]`；缺少版本元数据时不显示徽标。部署包可以单独替换任一值，而无须替换 New Session 控件或轨道几何；声明感知的 `slots.inject()` 让这种包无论先于还是后于侧边栏激活都能生效。
+`dsh-client-ui-sidebar` 是 dsh Web 客户端的侧边栏外壳：用户看到品牌行、启动新会话、折叠进布局拥有的 56px 轨道，并从底部固定的席位进入 Settings；可感知滚动的区域席位承载 Workspace 与 Session 浏览器。渲染到 `sidebar.workspaces` 的 Workspace 与 Session 浏览器归 ui-workspace 所有；本包既不派生其中的行，也不持有其视图偏好。部署包可以单独替换品牌标记或名称，而无须替换 New Session 控件或轨道几何；New Session 会针对显式指定、当前或最近活跃的 Workspace 启动运行时的页面局部前端 Session Intent。折叠到布局拥有的 56px 轨道仍属于本地呈现行为。

-栏内的滚动条是一种指针可供性：只要指针不在栏内，外壳就把 ui-theme 的[滚动条间接层](../ui-theme/README.zh.md)重新绑定为 `transparent`；指针离开后滑块再保留 2 秒，因此没人指向的列表不会带着滚动条。避免行位移的空间预留属于滚动区域本身（[ui-workspace](../ui-workspace/README.zh.md)），所以显示滑块不会引起重排。

-Skill invocation source, browser half: registers the `/`-trigger `skill` source into `ctx.inputTriggers`. Ordinary-session candidates come from the `skill.list` RPC addressed by the per-call `ClientSessionContext` projection's `{sessionId}`, with the host resolving `cwd` from the session header. The host serves every user-invocable skill; a `modelInvocable: false` entry (a `disable-model-invocation` skill, whose only entry point is this path) wears the user-only marker as a description prefix in the active language. Catalog-addressed continuable children resolve no skill candidates locally because the existing skill RPC requires an attached session; viewing their persisted history must not activate them. Catalogs cache per ordinary session with a single-flight fetch; the scope-birth `warm` hook prewarms the session's entry, the forwarded `agent-preset/selected` owner event drops that one session's entry (the catalog belongs to the preset, and a blank session may switch after the warm), and `connection/reset` clears everything. Results filter by `startsWith(query)`.
+## Summary
 
-A pick lands the literal `/name ` text and the prompt ships the same literal ([slash-pipeline Agent Note](../../../.agents/notes/implemented/architecture/2026-07-25-web-input-machine-and-slash-pipeline.md)) — this source implements no adjudication hooks and no reference codec. Determinism lives host-side: the pre-step gesture boundary (`dsh-tool-skill`) recognizes whitespace-bounded `/name` tokens naming user-invocable skills anywhere in a user message and injects the rendered `<skill_content>` for every entry point, so a menu pick, a hand-typed token, and a TUI/ACP prompt all load the skill the same way. A name shared with a host command still resolves to the command: adjudication claims the line client-side before it ever becomes a prompt — deliberate precedence, matching peer products. The list RPC rides the plugin's root-context connection captured at registration — the source never reads services off a per-call argument; draft chip visuals derive from the `lexicon` scan.
+`dsh-client-ui-skill` lets users invoke skills by typing `/name` in the composer: the suggestion menu offers user-invocable skills from the `skill.list` RPC, and a pick lands the literal `/name ` text that the host then loads as the skill's instructions. Loading is deterministic: the host's pre-step boundary (`dsh-tool-skill`) recognizes the whitespace-bounded `/name` token in the sent message and injects the rendered `<skill_content>` for every entry point, so a menu pick, a hand-typed token, and a TUI/ACP prompt all load the skill the same way. Settled skill calls render in the conversation as an expandable `Instructions` card, derived only from the frozen call/result slice.
 
-A failed `skill.list` throws from `candidates`, which the slash shell logs and folds into a silent menu-group drop — the menu shows only pending/ready states.
+## Table of Contents
 
-The `/client` exports are the plugin body (`apply`/`inject`) only; the source object is internal to the registration effect.

-## Skill tool row
+-----
 
-The browser plugin also registers the `skill` wire name in `ui-tool`'s keyed `tool.call.toolview` slot. A collapsed row renders the 14-pixel skill document-and-sparkle glyph, `Skill` title, separator, and requested skill name with the same neutral hierarchy as the Bash row; running calls carry the transcript shimmer, failures replace the name with the first error line, and interrupted calls use the warning state. A settled row expands as one whole-row disclosure into a bounded `Instructions` card containing the exact durable tool output, with the standard trajectory `Inspect` affordance when available. The row derives its name, lifecycle, and body only from the frozen call/result slice supplied by `ui-tool`, never from the current catalog, so replay remains stable when installed skills or their descriptions change.
+<a id="use-this-package"></a>
+## Use this package
 
+Type `/` in the composer and pick a skill from the suggestions, or type `/name` directly; the sent message carries the literal text, and the host loads the skill the same way for a menu pick or a hand-typed token. A name shared with a host command still resolves to the command — adjudication claims the line client-side before it ever becomes a prompt.
+
+### What the source offers
+
+Ordinary-session candidates come from the `skill.list` RPC; the host serves every user-invocable skill, and a `modelInvocable: false` entry (a `disable-model-invocation` skill, whose only entry point is this path) wears the user-only marker as a description prefix in the active language.

-Slot registry pure core, slot terminal design: SlotMap declaration merging, the single `register` composition API on SlotCore, the four-share component-props type family, the store-seat type family, and the renderer installation contract. React types only at runtime — the package is React-free and cordis-free.
+## Summary
 
-One `register({ name, children?, store?, inject?, ...kind }, Component)` call contributes a component into a declared slot and, in the same breath, declares child slots (declaration = render authorization = runtime spec, one table), a store seat, and the registrant's business face. The component is checked at the call site against `ComposedProps` — the intersection of four shares, each derived from its single source of truth:
+`dsh-client-ui-slots` is the pure core of the web client's slot system: the type-level contract every UI feature composes through. One `register({ name, children?, store?, inject?, ...kind }, Component)` call contributes a component into a declared slot and, in the same breath, declares child slots, a store seat, and the registrant's business face. The component is checked at the call site against `ComposedProps` — the intersection of four shares, each derived from its single source of truth — so a wrong composition fails to compile. Chain-kind slots invert keyed routing: entries self-nominate through a pure selector instead of the dispatch site picking an `entryKey`. The package is React-free and Cordis-free at runtime (React types only); `ui-renderer` owns the engine implementation and React bindings.
 
-| share | type | source |
-|---|---|---|
-| runtime | `PropsRuntime<K>` | SlotMap entry: `owner` (parent's renderSlot call site) + session standard kit + global seat |
-| child render | `PropsRenderSlots<S>` | the register call's `children` key set (statically narrowed `renderSlot`) |
-| store | `PropsStore<H>` | the declared handle: `useStore` selector hook + draft-stripped `actions` |
-| business | `I` | inferred from the `inject` factory's return |
+## Table of Contents
 
-Chain-kind slots invert keyed routing — entries self-nominate instead of the dispatch site picking an `entryKey`: each registration carries a pure `ChainSelect` selector (plus optional ascending `priority`, ties in registration order), the first non-null return elects its entry and becomes the component's `matched` prop, and all-null falls to the owner's `renderSlotChain` fallback (`ChainRenderOpts`).

-The standard-kit interfaces (`SessionStandardProps`, `GlobalStandardProps`) are declared empty here and merged by the runtime package (same declare-merge pattern as SlotMap keys). The renderer binds the runtime's session and workspace observable sources into selector hooks. Inject factory parameters derive from the declaration (`InjectParams`): session slots get `sessionId`, a declared store appends baked `actions`, nothing else — data access lives in the apply closure's ctx.
+-----
 
-The store family (`defineStore` spec in / `StoreHandle<T, A>` out) types the store seat: `init` infers the state schema, `actions` is the complete draft-transform write set, `BakedActions` strips the draft parameter into the callbacks components and inject factories receive. The `defineStore` value implementation lives in the runtime package (the engine's home) and satisfies the `DefineStore` contract exported here. Engine products and the renderer host contract carry bare snapshot sources (`getSnapshot`/`subscribe`), never React hooks — hook binding belongs to the render machinery; only the props-contract hook type (`SnapshotSelectorHook`) lives here.
+<a id="use-this-package"></a>
+## Use this package
 
-`SlotCore` seeds the a-priori `'root'` slot at construction and enforces load-time validation (undeclared-slot registration, duplicate child declaration, one shared handle under two scopes, a chain registration without `select` — all throw at register). An entry's disposer collapses its declared child slots recursively: ledger rows, contributions, and store mounts die on one lifecycle axis. Each key also carries a declaration epoch that advances only on declaration and collapse; `ui-renderer` uses it for [`ctx.slots.inject`](../../../.agents/notes/implemented/architecture/2026-08-05-slot-declaration-injection.md), independently from ordinary entry versions. `renderer.ts` carries the installation contract (`SlotRenderer`, `SlotRendererHost`) plus `StaleAuthorizationError`/`SlotOwnershipError`; ui-renderer owns both the implementation and its plugin-lifecycle installation.
+Compose UI through this package whenever you write a client plugin: register a component into a slot your parent declared, or declare child slots your component renders. The four kinds cover the composition shapes — `single` (one occupant), `list` (ordered entries), `keyed` (dispatch by a key), and `chain` (entries elect themselves).
 
+### The four props shares
+
+Every registered component receives props composed from four shares: the runtime share (`owner` from the parent's renderSlot call site, plus the session standard kit and global seat), the child-render share (`renderSlot` statically narrowed to the declared children keys), the store share (the declared handle's selector hook and draft-stripped actions), and the business share (inferred from the `inject` factory's return). Components reference `ComposedProps`; they never re-type a share locally.
+
+### Store seats
+
+A register call may declare a store seat with `store: defineStore(...)`: `init` infers the state schema and `actions` is the complete draft-transform write set. Components read through the selector hook and write through the baked callbacks; the engine implementation of `defineStore` lives in the runtime package and satisfies the `DefineStore` contract exported here.
+
+### Declaration discipline
+
+Declaring a slot is claiming it: the registering entry becomes the only entry allowed to render that key, and registering into an undeclared slot, declaring an already-declared child, mounting one shared handle under two scopes, or registering a chain without `select` throws at load. An entry's disposer collapses its declared child slots recursively — ledger rows, contributions, and store mounts die on one lifecycle axis.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+The design is one table: declaration = render authorization = runtime spec. `SlotMap` is declared empty here and merged by consumers via `declare module` augmentation, exactly like the standard-kit interfaces (`SessionStandardProps`, `GlobalStandardProps`), which the runtime package merges with real members.
+
+### Registration and routing
+
+`SlotCore` seeds the a-priori `'root'` slot at construction and enforces load-time validation. `ChainSelect` selectors run in ascending `priority` order (ties in registration order); the first non-null return elects its entry and becomes the component's `matched` prop, and all-null falls to the owner's `renderSlotChain` fallback (`ChainRenderOpts`). Each key carries a declaration epoch that advances only on declaration and collapse; `ui-renderer` uses it for `ctx.slots.inject`, independently from ordinary entry versions.
+
+### The renderer contract
+
+`renderer.ts` carries the installation contract (`SlotRenderer`, `SlotRendererHost`) plus `StaleAuthorizationError`/`SlotOwnershipError`; ui-renderer owns both the implementation and its plugin-lifecycle installation. Engine products and the renderer host contract carry bare snapshot sources (`getSnapshot`/`subscribe`), never React hooks — hook binding belongs to the render machinery.

-Slot 注册表纯核心、slot 终端设计：SlotMap 声明合并、SlotCore 上唯一的 `register` 组合 API、四 share 组件 props 类型家族、store seat 类型家族，以及 renderer 安装约定。只使用 React 类型；该包不依赖 React，也不依赖 Cordis。
+## 概述
 
-一次 `register({ name, children?, store?, inject?, ...kind }, Component)` 调用会向已声明 slot 贡献一个组件，同时声明子 slot（声明 = 渲染授权 = 运行时规范，三者共用一张表）、store seat 以及注册方的业务表层。组件会在调用点依据 `ComposedProps` 接受类型检查；该类型是四个 share 的交集，每个 share 都从各自的唯一真源派生：

-|---|---|---|
-| 运行时 | `PropsRuntime<K>` | SlotMap 条目：`owner`（父级 renderSlot 调用点）+ 会话标准工具包 + 全局 seat |

-标准工具包接口（`SessionStandardProps`、`GlobalStandardProps`）在这里声明为空，由运行时包合并（与 SlotMap key 相同的 declare-merge 模式）。renderer 会把运行时会话和 Workspace observable source 绑定为 selector 钩子。Inject factory 参数从声明派生（`InjectParams`）：会话 slot 获得 `sessionId`；声明 store 时追加 baked `actions`；没有其他参数，数据访问位于 apply 闭包的 ctx 中。

-store 家族（输入 `defineStore` 规范／输出 `StoreHandle<T, A>`）为 store seat 建模：`init` 推断状态 schema；`actions` 是完整的 draft-transform 写入集合；`BakedActions` 移除 draft 参数，成为组件和 inject factory 收到的回调。`defineStore` 值实现位于运行时包（引擎所属位置），并满足这里导出的 `DefineStore` 约定。引擎产物与 renderer host 约定携带裸快照 source（`getSnapshot`／`subscribe`），绝不携带 React 钩子；钩子绑定属于渲染机制，只有 props 约定钩子类型（`SnapshotSelectorHook`）位于这里。

+## 使用本包
 
-`SlotCore` 在构造时预置 `'root'` slot，并强制执行加载时验证（注册未声明 slot、重复声明子项、在两个 scope 下使用同一个共享 handle、chain 注册缺少 `select`，这些情况都在 register 时抛出）。条目的 disposer 会递归移除其声明的子 slot：账本行、贡献和 store 挂载都会随同一生命周期结束而移除。每个 key 还携带一个 declaration epoch（声明代次），它只在声明与移除时递增；`ui-renderer` 将其用于 [`ctx.slots.inject`](../../../.agents/notes/implemented/architecture/2026-08-05-slot-declaration-injection.zh.md)，且与普通条目版本相互独立。`renderer.ts` 携带安装约定（`SlotRenderer`、`SlotRendererHost`）以及 `StaleAuthorizationError`／`SlotOwnershipError`；ui-renderer 同时持有实现及其插件生命周期安装。
+编写客户端插件时都通过本包组合 UI：把组件注册进父级已声明的 slot，或声明组件将要渲染的子 slot。四种 kind 覆盖组合形态——`single`（单个占位者）、`list`（有序条目）、`keyed`（按键分派）与 `chain`（条目自行提名）。
 
+### 四个 props share
+
+每个已注册组件都会收到由四个 share 组合而成的 props：运行时 share（父级 renderSlot 调用点的 `owner`，加上会话标准工具包与全局席位）、child render share（静态缩窄到已声明 children key 的 `renderSlot`）、store share（已声明 handle 的 selector 钩子与移除 draft 的 actions），以及业务 share（从 `inject` factory 返回值推断）。组件引用 `ComposedProps`；它们绝不在本地重新输入任何 share。
+
+### Store 席位
+
+register 调用可以用 `store: defineStore(...)` 声明 store 席位：`init` 推断状态 schema，`actions` 是完整的 draft-transform 写入集合。组件经 selector 钩子读取、经烘焙回调写入；`defineStore` 的引擎实现位于 runtime 包，并满足这里导出的 `DefineStore` 约定。
+
+### 声明纪律
+
+声明即认领：注册条目成为唯一被允许渲染该键的条目；注册未声明 slot、声明已声明过的子项、在两个 scope 下挂载同一个共享 handle、或注册缺少 `select` 的 chain，都会在加载时抛出。条目的 disposer 会递归移除其声明的子 slot——账本行、贡献与 store 挂载都随同一生命周期结束而移除。

-Web subagent feature owner: contributes current-title lineage navigation to `conversation.session.header.lineage`, reason-specific read-only replacements to the conversation composer chain, and the existing `@` reference source to `ctx.inputTriggers`.
+## Summary
 
-The header lineage renderer reads `subagentsByParent` and session summaries through the standard `useSessions` hook. On an ordinary session it preserves the current title and, when descendants exist, appends `/` plus the descendant-count dropdown before the header action row. Every subagent breadcrumb uses the count trigger's 12px type scale and combines its title with a fixed double chevron; the current breadcrumb keeps primary color and weight 500, while ancestors use tertiary color and weight 400. Hovering a combined control for 150ms opens its direct-parent catalog, ArrowDown remains the keyboard entry path, and clicking an ancestor cancels a pending menu and navigates upward without opening it. Each catalog enables sibling switching and bolds its selected row; a catalog label overrides the session-summary title, and every switcher whose catalog has not loaded requests it automatically. Only the current subagent appends its own descendant-count dropdown. Long breadcrumb titles truncate while the chevron remains visible. The count trigger covers the complete subagent-only descendant lineage, stops at ordinary forks, and shows ongoing activity when any counted descendant is running. The compact tree remains direct-catalog authoritative: continuable and one-shot rows display mode plus `running`/`inactive` activity and an optional log-backed title, while the trailing column stacks total durable provider usage above active-turn duration. Token totals sum the four disjoint `tokenUsage` buckets. Visual duration stays exact to the second below one day, then uses at most two adjacent units—days/hours, approximate months/days, or approximate years/months—while hover and the accessible name retain the exact day/hour/minute/second value. Duration sums completed `subagentTiming` turns, advances once per second only for an open turn on a running child, and freezes after the child becomes inactive; an interrupted open turn is bounded by its same-cut `active.through`, never by newer session metadata. An unlabeled one-shot row falls back to its session id, while corrupt, unsupported, or unavailable rows remain readable but disabled. Each healthy row's `hasChildren` hint determines disclosure before interaction, so known leaves never show an arrow; a catalog level reserves the disclosure column only when at least one healthy row is a branch, allowing branchless levels to start at the leading status marker. Expanding a branch immediately reserves one disabled loading row per known direct descendant, then lazily replaces them with that child's authoritative catalog. Every visible branch is reported to the runtime so membership frames cause a debounced refresh only where the tree is being consumed. Selecting any depth calls `SessionRuntime.openSubagent()` with the row's exact `{parentSessionId, childSessionId, mode}` address. Component-local state owns tree visibility, expanded branches, keyboard focus, and the running-duration clock. ArrowRight/ArrowLeft expand and collapse branches; ArrowUp/ArrowDown, Home, End, and Escape navigate or close the tree; closing returns focus to the trigger. Styling uses tokens only.
+`dsh-client-ui-subagent` is the web client's subagent conversation feature: users browse and open subagent conversations from the parent session's header, continue them through reason-specific read-only composer states, and reference running children with the `@` source. From the parent session's header, users browse the complete subagent-origin descendant lineage — each row shows mode, running activity, token usage, and active-turn duration — and open any depth with the child's exact address. A one-shot child always opens a read-only composer identifying the transcript as a completed execution record; a continuable child routes follow-up prompts through its FIFO inbox while it runs. Subagent-origin Session rows are omitted from the ordinary sidebar, so the parent header catalog is their navigation entry point.
 
-A one-shot child always elects a read-only composer that identifies the transcript as a completed execution record. A continuable child does so only when its exact parent is unavailable and the child is not running, with copy explaining the recovery path; while such a child still runs, the selector yields to the ordinary composer, whose input and Send action are disabled but whose independent Stop stays usable, and the takeover returns once it stops. A continuable child with a live parent keeps the ordinary input chrome, whose Session routes prompts through `subagent.prompt`: typing and Send stay available while the child runs because every follow-up joins the child's FIFO inbox, while an independent Stop routes through `subagent.interrupt`. This package never receives host context or calls a model-facing tool. The catalog and composer behavior are specified by the [Web subagent conversations Agent Note](../../../.agents/notes/implemented/feature/2026-07-27-web-subagent-conversations.md) and the [current-turn interrupt Agent Note](../../../.agents/notes/implemented/feature/2026-08-06-continuable-subagent-interrupt.md).

+## Use this package
+
+The session header keeps the current session title as the lineage breadcrumb and, when the session has subagent descendants, appends a `/` count trigger before the header's action row; the trigger opens the descendant catalog, counts the complete subagent-only lineage, stops at ordinary forks, and shows ongoing activity when any counted descendant is running. Select any depth to open that child's conversation with its exact `{parentSessionId, childSessionId, mode}` address.
+
+### Browsing the tree
+
+Rows display mode plus `running`/`inactive` activity and an optional log-backed title; the trailing column stacks total durable provider usage above active-turn duration. Keyboard navigation works with ArrowRight/ArrowLeft to expand and collapse branches and ArrowUp/ArrowDown, Home, End, and Escape to navigate or close the tree. An unlabeled one-shot row falls back to its session id; corrupt, unsupported, or unavailable rows remain readable but disabled.

+
+### Catalog derivation
+
+The header lineage renderer reads `subagentsByParent` and session summaries through the standard `useSessions` hook. The compact tree remains direct-catalog authoritative: each healthy row's `hasChildren` hint determines disclosure before interaction, a catalog level reserves the disclosure column only when at least one healthy row is a branch, and expanding a branch immediately reserves one disabled loading row per known direct descendant before lazily replacing them with that child's authoritative catalog.

+These limits define what the catalog can show and what `@` references mean; they are current package constraints.

 - **The catalog has no durable outcome** — activity and timing do not distinguish completion, failure, or cancellation, and the UI exposes no Activation identity; stopping is limited to the composer's current-turn Stop for a running continuable child.

-Web subagent 功能 owner：向 `conversation.session.header.lineage` 贡献当前 title 谱系导航，向会话编辑器链贡献按原因区分的只读替代呈现，并保留注册到 `ctx.inputTriggers` 的既有 `@` 引用 source。
+## 概述
 
-页头谱系 renderer 通过标准 `useSessions` 钩子读取 `subagentsByParent` 与会话摘要。普通会话保留当前 title，并在存在后代时，于页头操作行之前追加 `/` 和后代数量下拉菜单。每一级 subagent 面包屑都使用数量触发器的 12px 字号，并将 title 与固定显示的双向箭头组合成一个控件；当前面包屑保留主标签颜色和 500 字重，祖先面包屑则使用三级标签颜色和 400 字重。悬停组合控件 150ms 后会打开其直接 parent 目录，ArrowDown 保留为键盘入口；点击祖先面包屑会取消待打开的菜单并仅向上导航。每个目录都可切换 sibling，并会加粗选中行；目录 label 优先于会话摘要 title，尚未加载目录的每个切换器都会自动请求该目录。只有当前 subagent 会追加自己的后代数量下拉菜单。过长的面包屑 title 会截断，而双向箭头始终保留。数量触发器会统计仅含 subagent 的完整后代谱系，在普通 fork 处停止，并在任一计入统计的后代处于 `running` 时显示活动仍在进行。紧凑树仍以直接目录为权威依据：可继续和 one-shot 行会显示 mode、`running`／`inactive` 活动状态和由日志支撑的可选 title，尾随列则在上行显示提供方的持久化 token 用量总计，在下行显示活跃轮次耗时。token 用量总计为四个互不重叠的 `tokenUsage` 桶之和。视觉耗时在不足一天时精确到秒，达到一天后则最多使用两个相邻单位——天／小时、近似月份／天或近似年份／月份——而悬停信息与无障碍名称会保留精确的天／小时／分钟／秒数值。耗时会累加已完成的 `subagentTiming` 轮次，仅在运行中 child 存在未结束轮次时每秒递增一次，并在 child 变为 inactive 后冻结；被中断的未结束轮次以其同一切面的 `active.through` 为上界，绝不使用更新的会话元数据。没有 label 的 one-shot 行会回退到其会话 id，而损坏、不受支持或不可用的行仍保持可读但禁用。每个健康行的 `hasChildren` 提示会在交互前决定是否显示展开控件，因此已知叶子节点从不显示箭头；每层目录仅在其中至少一个健康行是分支时才预留展开列，使完全不含分支的层级能从最前面的状态标记开始。展开分支时，会立即为每个已知直接后代预留一行禁用的加载行，随后再用该 child 的权威目录懒加载结果替换这些占位行。每个可见分支都会上报给运行时，使成员帧只在树正被消费的位置触发去抖动刷新。选择任意深度的条目都会使用该行的确切地址 `{parentSessionId, childSessionId, mode}` 调用 `SessionRuntime.openSubagent()`。组件局部状态负责树的可见性、已展开分支、键盘焦点与运行中耗时时钟。ArrowRight／ArrowLeft 展开和折叠分支；ArrowUp／ArrowDown、Home、End 与 Escape 用于导航或关闭树；关闭后焦点返回触发器。样式只使用 token。

 # @deepseek-ai/dsh-client-ui-theme
 
 English | [中文](README.zh.md)
 
-Theme plugin: ThemeRuntime over the --dsw-* token base stylesheets (static scale + alias semantic layers). The service owns the live theme preference (`light`/`dark`/`system`) and the conversation content font size (`fontSize`, integer px 12–17, default 14), resolves `system` through `prefers-color-scheme`, and publishes immutable `ThemeSnapshot`s on the `theme/change` event; it never touches the DOM — ui-layout's presenter applies the resolved snapshot (`html { color-scheme }`, `body[data-ds-dark-theme]`, `--dsh-content-font-size` on body, and inline alias tokens). A loopback browser provides the service immediately with the defaults, then loads the `ui-theme` namespace in the background and writes each accepted selection through the Host settings API, whose local provider stores it in `$DSH_HOME/settings.yaml` by default; pushed settings changes and reconnects refetch it, rapid selections are serialized in gesture order with namespace revisions, and a rejected latest write reloads the durable value. The Client keeps Host settings persistence disabled on non-loopback pages, so their selections remain process-local even though Connection authentication applies to every API method. Third-party registered theme ids remain an in-process extension and do not cross the built-in settings schema; removing one never overwrites the last durable built-in preference. The [Host-backed preferences decision](../../../.agents/notes/implemented/bug-fix/2026-08-06-host-backed-web-preferences.md) owns the persistence boundary. When the host composition includes an HTTP server, the host half injects a synchronous bootstrap immediately after the opening `<body>` tag. Each index response embeds the registered Host settings for `ui-theme` (preference and font size), or the schema defaults when no settings provider is present; the browser resolves `system` from the OS scheme, then sets `color-scheme`, `body[data-ds-dark-theme]`, and `--dsh-content-font-size` before the shell loading page renders. Compositions without an HTTP server remain unaffected, and ThemeRuntime and ui-layout remain authoritative for client state and subsequent DOM updates after the plugin tree activates.
+## Summary
 
-The plugin registers two rows into the settings General section: the Appearance preference cubes and the font-size stepper (12–17 px, centered value with hover-revealed up/down arrows, a px unit label after the pill). The font size drives `--dsh-content-font-size`; `gradient-shadow-text.css` derives `--dsh-content-font-delta` from it and shifts the markdown heading/base ladder by the same px increment, while table, small, and code variants stay fixed. Consumers outside the token ladder (the user bubble, the composer draft) read the same pair directly.
+`dsh-client-ui-theme` lets Web GUI users choose `light`, `dark`, or `system` and set conversation content text from 12 to 17 px in Settings. A loopback client stores both values in the `ui-theme` settings namespace, which the local provider persists in `$DSH_HOME/settings.yaml` by default. The plugin resolves `system` through `prefers-color-scheme` and publishes immutable `ThemeSnapshot`s; ui-layout applies each snapshot to the document. The package also ships the `--dsw-*` token stylesheets and injects a synchronous bootstrap so the selected palette and font size apply before the shell loads. Third-party themes can register alias-token overrides through `ctx.theme`.
 
-`src/styles/` holds five sheets imported in order by ui-theme's dynamic client entry: `base.css`, `design-platform.css`, `scrollbar.css`, `gradient-shadow-text.css`, and `shiki.css`. The client bundle compiles and injects them as plugin-owned global styles, so unload and HMR remove them with ui-theme instead of leaving theme CSS in the static web shell. `scrollbar.css` is the sole consumer of the `--dsw-alias-scrollbar-*` tokens and must follow `design-platform.css`, which declares them.
+## Table of Contents
 
-Scrollbar rebinding contract: `scrollbar.css` binds `--dsh-scrollbar-thumb` and `--dsh-scrollbar-thumb-hover` on `body` to the l1 (base-surface) tokens, and both rendering paths read that pair. An elevated surface (menu, popover, dialog) sets `--dsh-scrollbar-thumb: var(--dsw-alias-scrollbar-bg-l2)` and `--dsh-scrollbar-thumb-hover: var(--dsw-alias-scrollbar-hover-l2)` on its own container; one rebind retints whichever path the engine took. The pair's other legal target is `transparent`, which draws no thumb at all — [ui-sidebar](../ui-sidebar/README.md) rebinds its column that way while the pointer is elsewhere. A rebind to the l1 pair is not a rebind; it restates the base-surface default. `--dsh-scrollbar-width` mirrors the WebKit bar's layout width for surfaces that align themselves beside a space-consuming bar — [ui-conversation](../ui-conversation/README.md) reads it for the overlay composer seat's `right` offset — and the scrollbar-styles spec pairs it with the mirrored rule and the consumer.

-The two paths are mutually exclusive by construction. `scrollbar-width`/`scrollbar-color` sit inside `@supports not selector(::-webkit-scrollbar)` because a non-`auto` value of either makes Chromium and Safari discard every `::-webkit-scrollbar*` rule for that element, `::-webkit-scrollbar-thumb:hover` included — declaring both unconditionally leaves `--dsh-scrollbar-thumb-hover` with no rendering anywhere. Firefox therefore takes the standard properties and WebKit-based engines take the pseudo-elements, so the hover token only ever renders through the pseudo-element path. Reasoning and the measured computed values: [the scrollbar Agent Note](../../../.agents/notes/implemented/bug-fix/2026-07-28-themed-scrollbars-and-reserved-gutter.md).
+-----
 
+<a id="use-this-package"></a>
+## Use this package
+
+Users switch the color scheme and content font size from two rows in Settings (General section); both choices persist across restarts on a loopback browser. Feature plugins consume the current snapshot through `ctx.theme` and read the `--dsw-*` tokens in CSS; they do not manage theme state themselves.
+
+### Appearance and font size
+
+The plugin registers Appearance preference cubes and a font-size stepper in the General section. The stepper accepts integer values from 12 through 17 px and defaults to 14 px. It changes conversation headings and base text by the same increment, including the user bubble and composer draft; tables, small text, and code keep fixed sizes. Each accepted change writes through the Host settings API. Rapid changes serialize in gesture order with namespace revisions, and a rejected latest write reloads the durable values. Non-loopback pages keep both choices process-local.
+
+### Registering a theme
+
+A composition can register a third-party theme id with alias-token overrides through `ctx.theme`; the override layer folds into the active snapshot's tokens in registration order. Removing one never overwrites the last durable built-in preference. Third-party theme ids remain an in-process extension and do not cross the built-in settings schema.
+
+### Pre-plugin palette
+
+When the host composition includes an HTTP server, the host half embeds the registered `ui-theme` settings, or schema defaults, into each index response. Before the loading page renders, the browser sets `color-scheme`, `body[data-ds-dark-theme]`, and `--dsh-content-font-size`, so the first paint uses the selected palette and text size.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+The service owns theme and font-size state and publishes snapshots. The ui-layout presenter applies those snapshots, and the token sheets own the color and conversation text scales.
+
+### Stylesheets
+
+`src/styles/` holds five sheets imported in order by ui-theme's dynamic client entry: `base.css`, `design-platform.css`, `scrollbar.css`, `gradient-shadow-text.css`, and `shiki.css`. The client bundle compiles and injects them as plugin-owned global styles, so unload and HMR remove them with ui-theme. `scrollbar.css` is the sole consumer of the `--dsw-alias-scrollbar-*` tokens and must follow `design-platform.css`, which declares them.
+
+`gradient-shadow-text.css` derives `--dsh-content-font-delta` from `--dsh-content-font-size` and shifts the Markdown heading and base-text ladder by that increment. Dense table, small, and code variants stay fixed. The user bubble and composer draft consume the same variables outside that ladder.
+
+### Scrollbar rebinding
+
+`scrollbar.css` binds `--dsh-scrollbar-thumb` and `--dsh-scrollbar-thumb-hover` on `body` to the l1 base-surface tokens; an elevated surface (menu, popover, dialog) rebinds them to the l2 tokens on its own container, and the pair's other legal target is `transparent` (ui-sidebar rebinds its column that way while the pointer is elsewhere). `--dsh-scrollbar-width` mirrors the WebKit bar's layout width for surfaces that align beside a space-consuming bar. The two rendering paths are mutually exclusive by construction: Firefox takes the standard properties inside `@supports not selector(::-webkit-scrollbar)`, and WebKit-based engines take the pseudo-elements, so the hover token only ever renders through the pseudo-element path ([scrollbar note](../../../.agents/notes/implemented/bug-fix/2026-07-28-themed-scrollbars-and-reserved-gutter.md)).
+
+### Preference persistence
+
+The service provides itself immediately with the schema defaults on a loopback browser, then loads the `ui-theme` namespace and writes each accepted theme or font-size change through the Host settings API. Pushed settings changes and reconnects refetch the namespace. Non-loopback pages do not create that Host-backed scope. The persistence boundary is owned by the [Host-backed preferences note](../../../.agents/notes/implemented/bug-fix/2026-08-06-host-backed-web-preferences.md).

-主题插件：基于 --dsw-* token 基础样式表（静态尺度 + 别名语义层）的 ThemeRuntime。该服务拥有实时主题偏好（`light`／`dark`／`system`）与会话正文字号（`fontSize`，整数 px，12–17，默认 14），将 `system` 通过 `prefers-color-scheme` 解析为实际主题，并发布不可变的 `ThemeSnapshot`，通过 `theme/change` 事件通知变化；它绝不接触 DOM：ui-layout 的呈现器会应用解析后的快照（`html { color-scheme }`、`body[data-ds-dark-theme]`、body 上的 `--dsh-content-font-size`，以及主题的别名 token 内联变量）。来自回环地址的浏览器会先以默认值立即提供该服务，随后在后台加载 `ui-theme` namespace，并将每次通过的选择经 Host settings API 写入；其本地提供方默认将设置存入 `$DSH_HOME/settings.yaml`。收到推送的 settings 变更时或重连后，浏览器都会重新拉取该设置；连续快速选择会按操作顺序携带 namespace revision 串行写入，最新写入被拒时则重新加载持久化值。Client 在非 loopback 页面禁用 Host settings 持久化，因此这些页面的选择仍只保留在进程内，尽管 Connection 会认证每个 API 方法。已注册的第三方主题 id 仍是进程内扩展，不会跨越内置 settings schema；移除其中任意一个都绝不会覆盖最后一个持久化的内置偏好。该持久化边界由[Host settings 支撑的偏好决策](../../../.agents/notes/implemented/bug-fix/2026-08-06-host-backed-web-preferences.zh.md)拥有。 当主机组合包含 HTTP 服务器时，主机侧紧接 `<body>` 起始标签注入同步引导代码。每份 index 响应会嵌入已注册的 `ui-theme` Host 设置（主题偏好与字号），没有 settings provider 时则嵌入 schema 默认值；浏览器按操作系统配色解析 `system`，随后在外壳加载页面渲染前设置 `color-scheme`、`body[data-ds-dark-theme]` 与 `--dsh-content-font-size`。不含 HTTP 服务器的组合不受影响，插件树激活后，ThemeRuntime 与 ui-layout 仍分别是客户端状态和后续 DOM 更新的权威来源。
+## 概述
 
-插件向设置 General 区块注册两行：外观偏好方块与字号步进器（12–17 px，数值居中、hover 时显示上下箭头，药丸后带 px 单位标签）。字号驱动 `--dsh-content-font-size`；`gradient-shadow-text.css` 由它派生 `--dsh-content-font-delta`，让 markdown 标题／正文阶梯按同一像素增量整体平移，而表格、small 与 code 变体保持固定。token 阶梯之外的消费方（用户气泡、composer 草稿）直接读取同一对变量。
+`dsh-client-ui-theme` 让 Web GUI 用户在设置中选择 `light`、`dark` 或 `system`，并把会话正文字号设为 12 至 17 px。回环客户端把两个值存入 `ui-theme` 设置命名空间，本地提供方默认将其持久化到 `$DSH_HOME/settings.yaml`。插件通过 `prefers-color-scheme` 解析 `system` 并发布不可变的 `ThemeSnapshot`；ui-layout 把每份快照应用到 document。本包还提供 `--dsw-*` token 样式表，并注入同步引导，使所选调色板与字号在外壳加载前生效。第三方主题可通过 `ctx.theme` 注册别名 token 覆盖。
 
-`src/styles/` 下有五张样式表，由 ui-theme 的动态客户端 entry 依次导入：`base.css`、`design-platform.css`、`scrollbar.css`、`gradient-shadow-text.css` 与 `shiki.css`。客户端 bundle 将其编译并注入为插件持有的全局样式，因此卸载与 HMR 会随 ui-theme 一同移除这些样式，而不会把主题 CSS 留在静态 Web 外壳中。`scrollbar.css` 是 `--dsw-alias-scrollbar-*` token 的唯一消费方，必须排在声明这些 token 的 `design-platform.css` 之后。
+## 目录
 
-滚动条重新绑定约定：`scrollbar.css` 在 `body` 上把 `--dsh-scrollbar-thumb` 与 `--dsh-scrollbar-thumb-hover` 绑定到 l1（基础表面）token，两条渲染路径都读取这一组变量。高层级表面（菜单、浮层、对话框）在自己的容器上设置 `--dsh-scrollbar-thumb: var(--dsw-alias-scrollbar-bg-l2)` 与 `--dsh-scrollbar-thumb-hover: var(--dsw-alias-scrollbar-hover-l2)`；一次重新绑定即可为引擎实际走的那条路径换色。这组变量的另一个合法目标是 `transparent`，即完全不绘制滑块——[ui-sidebar](../ui-sidebar/README.zh.md) 在指针不在栏内时就这样重新绑定自己的列。绑回 l1 那组不算重新绑定，它只是重述基础表面的默认值。`--dsh-scrollbar-width` 镜像 WebKit 滚动条的布局宽度，供需要与占布局宽度的滚动条对齐的表面使用——[ui-conversation](../ui-conversation/README.zh.md) 用它作为覆盖 composer 座位 `right` 偏移——scrollbar-styles 规格把它与镜像规则及消费者配对检查。

-两条路径在构造上互斥。`scrollbar-width`／`scrollbar-color` 写在 `@supports not selector(::-webkit-scrollbar)` 之内，因为这两个属性中的任一个只要取非 `auto` 值，Chromium 与 Safari 就会丢弃该元素上的全部 `::-webkit-scrollbar*` 规则，`::-webkit-scrollbar-thumb:hover` 也在其中——若无条件地同时声明，`--dsh-scrollbar-thumb-hover` 在任何引擎上都不会被渲染。因此 Firefox 走标准属性，WebKit 系引擎走伪元素，hover token 只经由伪元素这条路径渲染。相关原理与实测计算值见[滚动条 Agent Note](../../../.agents/notes/implemented/bug-fix/2026-07-28-themed-scrollbars-and-reserved-gutter.zh.md)。

+<a id="use-this-package"></a>
+## 使用本包
+
+用户从设置（「通用」分区）的两行中切换配色方案与正文字号；在回环浏览器上，两个选择都会跨重启持久化。功能插件通过 `ctx.theme` 消费当前快照，并在 CSS 中读取 `--dsw-*` token；它们不自行管理主题状态。
+
+### 外观与字号
+
+插件在「通用」分区注册外观偏好方块与字号步进器。步进器接受 12 至 17 px 的整数，默认值为 14 px。它以相同增量调整会话标题与基础文本，包括用户气泡与 composer 草稿；表格、小号文本和代码保持固定字号。每次通过的变更都经 Host settings API 写入。连续快速变更按操作顺序携带命名空间 revision 串行写入，最新写入被拒时重新加载持久值。非 loopback 页面把两个选择都保留在进程内。
+
+### 注册主题
+
+组合可以通过 `ctx.theme` 注册带别名 token 覆盖的第三方主题 id；覆盖层按注册顺序折入活动快照的 token 中。移除其中一个绝不会覆盖最后一个持久化的内置偏好。第三方主题 id 仍是进程内扩展，不会跨越内置 settings schema。
+
+### 插件前调色板
+
+当主机组合包含 HTTP 服务器时，宿主侧会把已注册的 `ui-theme` 设置或 schema 默认值嵌入每份 index 响应。浏览器在加载页面渲染前设置 `color-scheme`、`body[data-ds-dark-theme]` 与 `--dsh-content-font-size`，因此首帧绘制就采用所选调色板与字号。

+
+`gradient-shadow-text.css` 从 `--dsh-content-font-size` 派生 `--dsh-content-font-delta`，并以该增量移动 Markdown 标题与基础文本阶梯。紧凑的表格、小号文本与代码变体保持固定字号。用户气泡与 composer 草稿在该阶梯之外消费相同变量。
+
+### 滚动条重新绑定
+
+`scrollbar.css` 在 `body` 上把 `--dsh-scrollbar-thumb` 与 `--dsh-scrollbar-thumb-hover` 绑定到 l1 基础表面 token；高层级表面（菜单、浮层、对话框）在自己的容器上把它们重新绑定为 l2 token；这组变量的另一个合法目标是 `transparent`（ui-sidebar 在指针不在栏内时就这样重新绑定自己的列）。`--dsh-scrollbar-width` 镜像 WebKit 滚动条的布局宽度，供需要与占布局宽度的滚动条对齐的表面使用。两条渲染路径在构造上互斥：Firefox 走 `@supports not selector(::-webkit-scrollbar)` 内的标准属性，WebKit 系引擎走伪元素，因此 hover token 只经由伪元素这条路径渲染（[滚动条笔记](../../../.agents/notes/implemented/bug-fix/2026-07-28-themed-scrollbars-and-reserved-gutter.zh.md)）。
+
+### 偏好持久化

+在 loopback 浏览器上，服务先以 schema 默认值立即提供自身，随后加载 `ui-theme` 命名空间，并把每次通过的主题或字号变更经 Host settings API 写入。收到推送的设置变更时或重连后都会重新拉取该命名空间。非 loopback 页面不会创建该 Host-backed scope。该持久化边界由 [Host 支撑的偏好笔记](../../../.agents/notes/implemented/bug-fix/2026-08-06-host-backed-web-preferences.zh.md) 拥有。

 ## Model Experience
 
-None, as this package renders already logged Tool calls and results without altering model requests, Tool execution, or session events.
+None, as the package is a browser-side tool presentation layer that renders logged calls without changing model context.
 
 #### KV Cache effect
 
-None. The package is client-only presentation.
+None; this package neither assembles nor sends a provider request.
 
 ## Known Limitations and Deferred Work
 
-- The Host excludes `run_code` from Code Mode program bindings, so production events produce one dispatch level; the recursive Runtime/UI contract supports nesting.
-- First-party Tool views are colocated here and can move to their owning business packages independently through the keyed slot.
-- Tool titles, row chrome, and every Cordis-free primitive label reuse the `ui-conversation` locale namespace; presenter models retain locale keys or data rather than rendered wording.

-Trajectory renders a turn-aware event ledger with selectable User, Assistant, Tool, and nested Subtool records. Thick rules mark Turn boundaries, compact inline markers identify Steps, and the main ledger keeps only index, event, and content; selection opens a local inspector for token usage, duration, Input, Output, and Timing. Durable image attachments in user input, assistant output, and tool results render through the `conversation.trajectory.images` gallery slot: a record without text labels its row with the image count, the inspector shows each image with the shared loading, retry, and lightbox behavior, and image URLs come from the Conversation-owned per-session cache, so Chat and Trajectory share one authorized read per attachment. Scrollable Summary regions keep their scrollbar thumbs transparent until the region is hovered or contains keyboard focus, without changing the reserved scroll geometry. A standalone compaction request appears chronologically in its own `Between turns` section, while a numbered compaction remains inside its owning turn. Long ledgers open at the current tail, load one older page when the user reaches the loaded range's top, and mount only the visible row window plus a small overscan; request-only separators share the next measurable virtual item, while semantic row keys and ARIA indexes survive prepends. Selection, timeline navigation, folding, search, and Request totals cover the currently loaded window. The ledger covers records with an explicit loading row until the initial tail is positioned. While an older prefix remains unloaded, a first-row control precedes the loaded records, loads one earlier page on click, and changes in place to a disabled loading status while that page is pending. A fixed Overview above the ledger projects real record start/duration timing from left to right; when earlier records remain unloaded and the viewport includes the loaded domain's start, a neutral ellipsis control identifies the omitted prefix and loads one earlier page without assigning unknown history fabricated duration. Assistant spans divide recorded TTFT from decoding, and a 500 ms hover reveals exact clock and duration details. Dragging an interval focuses the ledger on every record active at any point in that inclusive range, while clearing the selection restores the full loaded ledger. Wheel gestures zoom the time domain. A right-button click clears the selected interval, while a right-button drag pans an already zoomed viewport without changing it. The initial view and streaming updates stay at the tail; scrolling upward suspends following so new records do not interrupt inspection of earlier rows. Content-only stream frames preserve virtual row keys and heights, reuse measurements, and do not issue repeated tail-scroll writes. Completed replies retain assembled blocks, timing, and usage in Trajectory target State, while the shared Session window keeps standard events and packed historical Assistant runs. Trajectory asks the conversation shell to float the composer over the full-height ledger, while its responsive vertical scrollers reserve the composer's live height so final rows remain reachable. Trajectory-owned Definitions assemble business records, including durable cancellation-finalized prefixes, chunk-only interruption fallbacks, and interrupted Tool records, from the shared Session window and fold packed runs without member expansion, so Trajectory neither reads nor changes the Chat conversation snapshot. The package provides no service and declares no Context merge; it registers target-specific Event Definitions, a Trajectory view builder, and one tab in the conversation's `'conversation.view'` slot ring. Its typed `trajectory` locale namespace owns every product-authored ledger, timeline, inspector, tooltip, and accessibility phrase; event content, tool names, identifiers, and provider diagnostics remain verbatim data.

Thick rules mark Turn boundaries, compact inline markers identify Steps, and selecting a record opens a local inspector for token usage, duration, Input, Output, Timing, and durable images from user, assistant, or tool content. The view is a pure consumer: it registers target-specific Event Definitions, a Trajectory view builder, and one tab in the conversation's `conversation.view` slot ring, and provides no service and declares no Context merge.

+## Use this package
+
+Open the Trajectory tab in the conversation's view ring to inspect agent activity as an event ledger and timeline. The ledger covers records with an explicit loading row until the initial tail is positioned; while an older prefix remains unloaded, a first-row control loads one earlier page on click and shows a disabled loading status while that page is pending.
+
+### Inspecting records
+
+Selection, timeline navigation, folding, search, and Request totals cover the loaded window. Selecting a record opens a local inspector for token usage, duration, Input, Output, Timing, and durable images. Image URLs use the Conversation-owned per-session cache, so Chat and Trajectory share one authorized read per attachment. A record without text labels its row with the image count. A standalone compaction request appears chronologically in its own `Between turns` section, while a numbered compaction remains inside its owning turn.
+
+### The timing overview
+
+A fixed Overview above the ledger projects real record start/duration timing from left to right; Assistant spans divide recorded TTFT from decoding, and a 500 ms hover reveals exact clock and duration details. Dragging an interval focuses the ledger on every record active at any point in that inclusive range; wheel gestures zoom the time domain; a right-button click clears the selected interval, and a right-button drag pans an already zoomed viewport.

+
+The view is a pure projection: Trajectory-owned Definitions assemble business records from the shared Session window — including durable cancellation-finalized prefixes, chunk-only interruption fallbacks, and interrupted Tool records — so Trajectory neither reads nor changes the Chat conversation snapshot.
+
+### Virtual rows
+
+Long ledgers mount only the visible row window plus a small overscan; request-only separators share the next measurable virtual item, while semantic row keys and ARIA indexes survive prepends. Content-only stream frames preserve virtual row keys and heights, reuse measurements, and do not issue repeated tail-scroll writes. Completed replies retain assembled blocks, timing, and usage in Trajectory target State, while the shared Session window keeps the raw Events.
+
+### Layout
+
+Trajectory asks the conversation shell to float the composer over the full-height ledger, while its responsive vertical scrollers reserve the composer's live height so final rows remain reachable. Scrollable Summary regions keep their scrollbar thumbs transparent until hovered or focused, without changing the reserved scroll geometry. The package provides no service and declares no Context merge.

-Trajectory 渲染按轮次组织的事件记录表，其中可选择用户、助手、工具和嵌套子工具记录。较粗的分割线标示轮次边界，紧凑的行内标记标识步骤，主记录表仅保留索引、事件和内容；选择记录则会打开局部检查器，查看 token 用量、耗时、输入、输出和计时。用户输入、助手输出和工具结果中的持久化图片附件通过 `conversation.trajectory.images` 画廊 slot 渲染：没有文本的记录行以图片数量标注，检查器内展示每张图片并复用共享的加载、重试与灯箱行为，图片 URL 来自 Conversation 持有的按会话缓存，因此 Chat 与 Trajectory 对同一附件共享一次经会话授权的读取。可滚动的概述区域默认保持滚动条滑块透明，直到鼠标悬停该区域或其中包含键盘焦点时才显示，同时不改变滚动条预留的几何空间。独立运行的压缩（compaction）请求会按时间顺序显示在自己的 `Between turns` 区段中，而带编号的压缩仍位于其所属轮次内。长记录表打开时定位于当前尾部，用户到达已加载范围顶部时加载一页更早的历史，并且只挂载可见行窗口和少量额外缓冲行；仅含请求的分隔行并入下一个具备可测高度的虚拟项，语义行键和 ARIA 索引在向前补页后保持不变。选择、时间线导航、折叠、搜索和请求汇总只覆盖当前已加载的窗口。初始尾部完成定位前，记录表会用明确的加载行遮住真实记录。更早的前缀仍未加载时，已加载记录前会始终保留首行控件；单击它会加载一页更早的历史，页面加载期间则会原地变为禁用的加载状态。固定在记录表上方的 Overview 区域从左到右投影记录的真实开始时间与耗时；仍有更早记录未加载且 viewport 包含已加载时间域起点时，中性的省略号控件会标识被省略的前缀，并可加载一页更早历史，而不会为未知部分虚构耗时。助手时间条会区分记录到的 TTFT 与解码时间，悬停 500 ms 后可查看精确时刻和耗时详情。拖选一个区间会将记录表聚焦到活动区间与该闭区间有重叠的所有记录，清除选择则恢复完整的已加载记录表。滚轮手势用于缩放时间域。右键单击会清除所选区间；在已放大的 viewport 上按住右键拖动则只会平移视图，不会改变该区间。初始视图和流式更新都会停留在尾部；向上滚动会暂停跟随，因此新记录不会打断对旧记录的检查。仅含内容更新的流式帧会保持虚拟行的键和高度不变、复用测量结果，并且不会重复写入末尾滚动位置。已完成的回复会在 Trajectory target State 中保留组装后的 blocks、计时与用量，共享 Session 窗口则保留标准 event 与 packed Assistant 历史 run。Trajectory 要求会话壳将 composer 作为浮层置于全高记录表上方；其响应式纵向滚动容器会预留 composer 的实时高度，确保仍可滚动到最后几行。Trajectory 自有的 Definition 从共享 Session 窗口组装业务记录，其中包括持久化的取消定稿前缀、只能从分片恢复的打断前缀和被打断的工具记录，并直接 fold packed run 而不展开 member，因此 Trajectory 既不读取也不改变 Chat 会话快照。该包不提供 service，也不声明 Context 合并；它会注册 target 专属 Event Definition、Trajectory view builder，以及会话 `'conversation.view'` slot 环中的一个视图标签页。其 typed `trajectory` locale namespace 持有 ledger、时间线、检查器、tooltip 与无障碍短语中的全部产品编写文案；事件内容、工具名称、标识符与提供方诊断仍作为数据原样呈现。

 English | [中文](README.zh.md)
 
-Web question feature plugin: its browser half registers the `question` entry in the conversation-owned `conversation.composer` keyed slot. Its host half is empty on purpose — mounting `dsh-tool-ask-user` there put the tool in the registry's GLOBAL layer, which merges into every agent regardless of the preset that composed it, so a two-tool benchmark preset really presented three. Rendering a question is a host UI capability; having the tool is an agent capability, so the `tool-ask-user` row belongs to the presets that want it (and to the TUI composition, which has no presets).
+## Summary
 
-The component renders one question at a time with progress navigation, single- and multi-select choices, recommendation badges derived from label suffixes, and custom answers. A multi-select draft keeps its selected labels while the user opens or edits the custom answer, so its submitted item may carry both `selected` and `custom`; a single-select custom answer remains exclusive. Question detail reuses the assistant-output `MarkdownText` primitive, including its GFM rendering and untrusted-content policy. The capped card keeps its title, navigation, and submission actions fixed while long detail and choices share an internal scroll region. Both question shapes answer into a textarea over a hidden height mirror, so a long answer soft-wraps and grows the field in place; growth stops at six lines of text — the same count in both variants — and the field scrolls from there, keeping the choices the answer belongs to in view. Single-select choices advance immediately, Enter continues the flow and submits once every question is answered or skipped, and Shift+Enter breaks a line instead; Enter during IME composition confirms the input candidate without advancing. It submits one structured answer batch for the whole request: “Skip this question” retains other drafts and emits the existing blank `{ selected: [] }` shape for that item, while close rejects the whole wait as `ASK_CANCELLED`.
+`dsh-client-ui-user-questions` is the web question feature plugin: its browser half registers the `question` entry in the conversation-owned `conversation.composer` keyed slot, so when the agent asks the user a question the composer is taken over by the question UI. The component renders one question at a time with progress navigation, single- and multi-select choices, recommendation badges, and custom answers, and submits one structured answer batch for the whole request. A request whose single question declares a presentation intent renders as that intent's own surface instead — notably the `plan-review` waiting-approval card with `Chat about it` / `Refuse` / `Approve`. Its host half is empty on purpose: mounting `dsh-tool-ask-user` there would put the tool in the registry's global layer and merge it into every agent regardless of the preset that composed it.
 
-A request whose single question declares a presentation intent renders as that intent's own surface instead. `plan-review` — set by `dsh-plan-mode` on the `exit_plan_mode` review — takes the waiting-approval card shape: a `Plan review` strip, the plan as the scrolling markdown body, the question text as the card's accessible name, and one decision row of `Chat about it` / `Refuse` / `Approve`. Approve and Refuse answer with the asker's own option labels (the intent names which label approves, so the verdict never rides option order) and keep the asker's descriptions as tooltips; `Chat about it` rejects the wait as `ASK_CANCELLED`, returning the composer so the user can say what they want instead. The card claims a request only when it can send every answer that request allows: one question, the intent declared, the plan present as `detail`, the named approve label offered, and a binary single choice (at most one option besides approve, not multi-select). Anything else — no intent, a batch of several questions, a missing plan, an approve label naming no option, a third option, a multi-select decision — stays on the generic flow, which can express it. An intent changes the layout, never which answers are reachable.

-Selection state is local to a component keyed by the request rpcId. A replay with the same id preserves a still-mounted draft, while `question/resolved` from the host removes the composer. The host remains authoritative: successful HTTP delivery does not remove pending state locally.

+## Use this package
+
+When the agent asks a question, the composer becomes the question surface: answer each question, navigate with the pager, or skip it. Single-select choices advance immediately; Enter continues the flow and submits once every question is answered or skipped, while Shift+Enter breaks a line instead (during IME composition Enter only confirms the input candidate without advancing).
+
+### Answering
+
+A multi-select draft keeps its selected labels while the user opens or edits the custom answer, so its submitted item may carry both `selected` and `custom`; a single-select custom answer remains exclusive. Question detail reuses the assistant-output `MarkdownText` primitive, including its GFM rendering and untrusted-content policy.

+### The plan-review card
+
+A `plan-review` intent — set by `dsh-plan-mode` on the `exit_plan_mode` review — renders the waiting-approval card shape: a `Plan review` strip, the plan as the scrolling markdown body, and one decision row of `Chat about it` / `Refuse` / `Approve`.

+
+### Copy and locale
 
 Composer chrome copy (pager, buttons, placeholders, validation feedback) is bilingual: the plugin registers zh/en dictionaries under the `question` namespace of `dsh-client-locale` and hands the entry its bound translator plus the locale snapshot source through the inject face, so a locale switch re-renders a mounted composer. Question and option text arrives from the model and renders verbatim; carrier failure messages also display untranslated.

-Web 提问功能插件：其浏览器侧把 `question` 条目注册到会话拥有的 `conversation.composer` 键控 slot 中。其主机侧刻意为空——在那里挂载 `dsh-tool-ask-user` 会把工具放进注册表的**全局层**，而全局层会并入每一个 agent（智能体），无论它由哪个 preset 组装，于是一个「两工具」的 benchmark preset 实际会呈现三个。渲染提问是宿主的 UI 能力，拥有该工具则是 agent 的能力，因此 `tool-ask-user` 行属于需要它的各个 preset（以及没有 preset 的 TUI 组装）。
+## 概述
 
-组件每次渲染一个问题，提供进度导航、单选和多选选项、由标签后缀派生的推荐徽标，以及自定义答案。用户打开或编辑自定义答案时，多选题草稿会保留已选中的标签，因此提交项可以同时携带 `selected` 与 `custom`；单选题的自定义答案仍保持互斥。问题详情复用助手输出的 `MarkdownText` 原语，包括其 GFM 渲染与不受信任内容策略。限高卡片保持标题、导航与提交动作固定，超长的详情与选项共享内部滚动区。两种问题形状的自定义答案都写入一个带隐藏高度镜像的 textarea，因此长答案会软换行并就地把输入框撑高；增高到六行文本为止——两种形状行数相同——此后由输入框自身滚动，使答案所属的选项仍留在视野内。选择单选选项后会立即前进；Enter 继续流程，所有问题均已回答或跳过后即提交，Shift+Enter 则改为换行；IME 组合输入期间按 Enter 只会确认输入候选，不会前进。组件为整个请求提交一批结构化答案：「跳过此问题」会保留其他草稿，并为该项发出既有的空 `{ selected: [] }` 形状；关闭则以 `ASK_CANCELLED` 拒绝整个等待。

-The browser plugin that reconstructs durable top-level workflow runs as independent Chat nodes. It consumes the four `tool-workflow/*` Session events owned by [`dsh-tool-workflow`](../../workflow/tool-workflow/README.md), registers one `ConversationNodeDefinition`, and renders through the keyed `conversation.chat.node` slot without changing the existing workflow tool card.
+## Summary
 
-## Durable state and replay
+`dsh-client-ui-workflow-run` is the browser plugin that reconstructs durable top-level workflow runs as independent Chat nodes in the dsh web client. It consumes the four `tool-workflow/*` Session events owned by `dsh-tool-workflow`, registers one `ConversationNodeDefinition`, and renders through the keyed `conversation.chat.node` slot without changing the existing workflow tool card. The run and each phase are controlled disclosures: a mount opens running, failed, cancelled, and interrupted levels and closes fully completed levels, and users can toggle either level with the full row, Enter, or Space. A member opens a child Session only while every current fact agrees, and the node shows run, phase, member identity, and status only.
 
-`tool-workflow/run-start` creates one Context keyed by `runId`; member starts, member endings, and the run ending update that Context in log order. A history tail containing only updates remains pending until an older page supplies the unique start, after which prepend, complete replay, and live append produce the same state. A closed Turn or Step with missing terminal events presents the affected run or members as interrupted without changing the tool result.
+## Table of Contents
 
-Phase groups come only from members that actually started. Exact phase strings share a group, an omitted phase is distinct from the empty string, and settlement changes status without removing or reordering members.

-## Presentation and navigation
+-----
 
-The run and each phase are controlled disclosures in every status. A mount opens running, failed, cancelled, and interrupted levels and closes fully completed levels; users can then toggle either level with the full row, Enter, or Space. Ordinary running updates preserve the current choice, the first abnormal edge opens once, normal completion closes once, and a completed phase plus the outer run open again when a new running member starts under the same phase key. If an entire new clean cycle arrives in one render while the run remains active, the phase finishes folded but the outer run opens once to expose its updated summary. Completion updates the visible status immediately but delays its automatic close while focus remains inside the content. `WorkflowRunPanel` owns the phase choices, so closing and reopening the outer run does not reset them; a renderer remount reconstructs every initial choice from durable facts. The run uses a 32-pixel `--dsw-alias-bg-module-platform` row with persistent right/down chevrons and an inline state dot plus status text, without a badge. Phases use 32-pixel disclosure rows with title and member count in the flexible main area and a fixed precise aggregate-status tail, without another dot. Members use a 16-pixel dot slot, a truncating name area, and a fixed 64-pixel status column.

+## Use this package
 
-A member opens a child Session only while every current fact agrees: the member is running, the child id is in the ordinary Session list, the row has `origin: 'subagent'`, its `parentId` is the current Session, and the list row is still running. Underlined member text is the only visible navigation affordance; keyboard focus draws a two-pixel business-primary ring around the name area, while status copy remains `Running`. The component calls only the injected ordinary `sessions.open(id)` action; remote, addressed-only, wrong-parent, or terminal rows remain non-interactive.
+A top-level workflow run through `dsh-tool-workflow` appears in the conversation as its own node: expand the run to see its phases, and expand a phase to see its members. Phase groups come only from members that started, and settlement changes status without removing or reordering members.
 
-## Composition
+### Navigating the node
 
-The package registers its Definition, locale dictionary, and `workflow-run` renderer as Cordis effects. Removing the client entry retracts all three contributions. The shipped Web bundle includes the plugin after `ui-conversation` and `ui-tool`.

+
+The node is a deterministic replay of durable session events: `tool-workflow/run-start` creates one Context keyed by `runId`, and member starts, member endings, and the run ending update that Context in log order. A history tail containing only updates remains pending until an older page supplies the unique start, after which prepend, complete replay, and live append produce the same state.
+
+### Disclosure choices
+
+Ordinary running updates preserve the current choice, the first abnormal edge opens once, normal completion closes once, and a completed phase plus the outer run open again when a new running member starts under the same phase key. If an entire new clean cycle arrives in one render while the run remains active, the phase finishes folded but the outer run opens once to expose its updated summary. `WorkflowRunPanel` owns the phase choices, so closing and reopening the outer run does not reset them; a renderer remount reconstructs every initial choice from durable facts.

+kind: "package-reference"

 # @deepseek-ai/dsh-client-ui-workspace
 
 English | [中文](README.zh.md)
 
-Shared Workspace browser and picker plugin. `WorkspaceBrowser` fills the sidebar's `sidebar.workspaces` slot, while `WorkspacePicker` fills the page-local Session Intent hero's `conversation.hero.workspace` slot; both surfaces use the same Workspace menu and add flow.
+## Summary
 
-The browser renders grouped or flat Session rows from the global runtime hooks and owns Workspace add/rename/reorder plus Session reorder. A Workspace remembers whether it is closed or showing Sessions; an open Workspace shows five non-blank Sessions by default, keeps the selected blank **New Session** as one provisional extra row until its first prompt, offers a transient **Show more** control for the hidden remainder, and returns to that folded projection after the whole Workspace is closed and reopened. Creating a Session from a Workspace row first opens that group so the new row remains visible when the Session state arrives. Once the Workspace list baseline is ready, browser-persisted expansion and Session-order records retain only current Workspace ids plus Ungrouped and the flat-list account. View options combine grouping with one browser-persisted Session order per account: real Workspaces initialize from `WorkspaceView.sessionIds`, while Ungrouped and the cross-Workspace flat list initialize from recency. **Manual** and **Last updated** apply in either presentation. Entering Last updated performs a complete recency sort and later user prompts or steers promote their Session once, while entering Manual preserves every current position and disables later promotion. Dragging edits the current order in either mode; Manual-mode drags for real Workspaces also update the Host Session account, while Ungrouped and flat-list orders remain browser-local because neither has one Workspace account. A collapsed group resolves drag boundaries from its rendered rows and places the source ahead of intervening hidden rows, so the dragged row cannot disappear into the remainder. Flat rows omit the empty leading status slot because they have no parent hierarchy, but retain it when a Session status is visible. Workspace drag order is Host-durable in either Session order mode.
+`dsh-client-ui-workspace` is the shared Workspace browser and picker of the dsh web client: users browse grouped or flat Session rows in the sidebar, pick a Workspace for a new session from the Session Intent hero, and manage Workspaces and Sessions with add, rename, reorder, search, fork, and archive actions; the same Workspace menu and add flow serve both surfaces. Pending user interactions surface as amber warning dots, and the shared sidebar projection hides subagent-origin sessions. Distinct canonical paths remain separate id-keyed Workspaces, and adding a folder goes through a directory-flow child hole that a composed picker package's client half fills.
 
-Collapsed search is one header action beside the view and add actions. In the rail, add and search render as 36px controls on the shell's shared horizontal entry path. Activating search expands the field across the header; an outside click collapses only a query that is empty after trimming — except while the rail search gesture is still in flight (until focus lands in the input after the column slide), so the expanding click cannot dismiss the search it opened — while the clear control always resets and collapses it. A non-blank search query replaces either browsing mode with one flat result list: case-insensitive title and Workspace substring matches appear immediately, while a 250 ms debounced Host request adds ranked current-conversation content matches and snippets. The English search input and its defensive request path remove NUL, cap the query at the wire schema's 500 UTF-16 code units without splitting a surrogate pair, and preserve the existing debounce and cancellation behavior. Each new query aborts the preceding request; a failed content search leaves metadata matches visible with a warning. The list is capped at 20, asks the user to narrow broader queries, and opens the selected Session without clearing the query or jumping to a specific event.
+## Table of Contents
 
-The picker lists real Host Workspace entities through the global `useWorkspaces` hook. Selecting a Workspace invokes the slot owner's `onPick` callback to retarget the frontend Session object. Distinct canonical paths remain separate id-keyed Workspaces when their basenames and display titles match; the sidebar hover detail shows a POSIX home or descendant as `~` / `~/…` and leaves a Windows path verbatim. Each registration declares a **directory-flow child hole** (`single` kind: `conversation.hero.workspace.directoryFlow` / `sidebar.workspaces.directoryFlow`) that the composed picker package's client half fills with its picking interaction — the [`-native`](../../host/directory-picker-native/README.md) backend's renderless OS-chooser driver in the standard composition, an in-app browsing dialog under a `-browse` composition. The flat **Add workspace...** action renders only while the surface's hole is occupied (occupancy read per menu render; an empty hole means the composition has no picking affordance — the seam's documented no-flow default, under which the sidebar header drops its add button rather than offering a dead one). This package owns the trigger and the adoption: the occupant reports one picked path per open through the hole's owner conversation (`open`/`busy`/`onPicked`/`onCancel`/`onError`), and the owner adopts it through the object layer, selecting the committed Workspace only after its list projection has refreshed; cancellation is silent, and errors land in the retryable folder dialog whose **Choose again** reopens the flow. Adding has exactly one route: the occupant's own create-folder affordance already covers a brand-new directory, so no separate create-by-name dialog exists. A menu only appears where there is something to choose between — with no Workspace listed, the anchor gesture raises the flow directly instead of a one-row popover, and it waits for the list baseline before treating an empty list as final. The runtime Session and Workspace services own materialization. The Workspace row's Delete action opens a confirmation that states the retention boundary, blocks duplicate submission, and keeps failures open; success removes the group while its Sessions remain under Ungrouped. The Session row's Rename action opens the same browser-owned dialog pattern prefilled with the row's display title: no client-side conflict rule exists (the host normalizes and may reject with `title-invalid`, rendered in the dialog alert), and confirming an unchanged title is deliberately allowed — it pins the current automatic title against regeneration. The Session row's Archive action commits without a confirmation dialog (non-destructive: the log and the workspace accounting slot remain) through `ctx.workspaces.archiveSession`; the row disappears from every grouping surface — workspace groups, Ungrouped, content search, and the flat list — when the archive-set echo lands, and failures are console diagnostics that leave the tree unchanged. A blank New Session row is a pure placeholder: it renders no row menu and no time label (nothing has happened in it yet), so rename, fork, and archive first apply once the first prompt lands.

-Workspace and Session hover cards copy the value their row clips: activating a Workspace card writes its full directory path, while activating a non-blank Session card writes its full display title. A provisional blank New Session card remains read-only because its localized label is a placeholder rather than session content. The card reports the dictionary-driven copied state only after the browser accepts the clipboard write.
+-----
 
-The Session row's Fork action forks at the source's last completed turn, increments the inherited persisted title on the client, and then opens the child; a trailing ASCII or fullwidth parenthesized number is incremented in the same style, while an unnumbered title gets ` (1)` appended. The source and child always appear as peer rows within a workspace group, with lineage retained only as session data. A fork or rename failure leaves the current selection unchanged; after a rename failure, the created child remains in the list.
+<a id="use-this-package"></a>
+## Use this package
 
-Session rows render the runtime's live `pendingInteraction` classification: approvals report **Waiting for approval**, plan reviews report **Plan awaiting review**, and ordinary questions report **Waiting for answer**. Every pending interaction uses an amber warning dot that takes precedence over the running indicator; ordinary rows repeat the localized status in their hover card, and both ordinary and search-result rows carry the same text as a visually hidden label for assistive technology. Running uses the blue indicator and its hidden label; an idle row leaves the reserved status slot empty.
+Use the sidebar to browse Workspaces and their Sessions, reorder them, and start new ones; use the picker in the Session Intent hero to choose a Workspace for a new session. An open Workspace shows five non-blank Sessions by default and keeps the selected blank **New Session** as one provisional extra row until its first prompt. **Show more** reveals the hidden remainder; closing and reopening the Workspace restores this folded projection.
 
-Both target slots are declared by other plugins, so `apply` uses `slots.inject()` to register for each declaration lifetime and re-register after a declaring slot is restored.
+### Reordering and view options
 
-The shared sidebar projection hides rows whose durable Session summary has `origin: 'subagent'`; users enter those conversations through the selected parent's subagent header catalog. Each visible ordinary row inherits the blue activity indicator while any descendant reached through uninterrupted subagent-origin lineage is running, and its hover and assistive text report the exact running-descendant count without describing an idle parent as running. Ordinary forks remain visible and terminate this aggregation because lineage alone does not set their origin. Pending user interaction outranks the session's own running state, and either remains the primary row status while descendant activity stays available as a separate hover and assistive status. With neither present, descendant activity outranks the green unviewed-completion reminder; the reminder returns once no descendant is running. The runtime keeps hidden rows available for conversation, title, and addressed transport state.
+View options combine grouping with one browser-persisted Session order per account: **Manual** and **Last updated** apply in either presentation. Entering Last updated performs a complete recency sort and later user prompts or steers promote their Session once; entering Manual preserves every current position and disables later promotion. Dragging edits the current order in either mode; Manual-mode drags for real Workspaces also update the Host Session account, while Ungrouped and flat-list orders remain browser-local. In a collapsed group, drag boundaries follow rendered rows and place the source before intervening hidden rows, so a drag cannot hide its source. Workspace drag order is Host-durable in either Session order mode.
 
+### Search
+
+Collapsed search is one header action beside the view and add actions: activating it expands the field across the header. A non-blank query replaces either browsing mode with one flat result list — case-insensitive title and Workspace substring matches appear immediately, while a 250 ms debounced Host request adds ranked current-conversation content matches and snippets. Each new query aborts the preceding request; a failed content search leaves metadata matches visible with a warning. The list is capped at 20 and opens the selected Session without clearing the query.
+
+### Managing sessions
+
+The Session row's Rename action opens a dialog prefilled with the row's display title; confirming an unchanged title is deliberately allowed — it pins the current automatic title against regeneration. Archive commits without a confirmation dialog and the row disappears from every grouping surface when the archive-set echo lands. Fork forks at the source's last completed turn, increments the inherited persisted title on the client, and then opens the child. Workspace Delete opens a confirmation that states the retention boundary; success removes the group while its Sessions remain under Ungrouped.
+
+### Pending interactions
+
+Session rows render the runtime's live `pendingInteraction` classification: approvals report **Waiting for approval**, plan reviews report **Plan awaiting review**, and ordinary questions report **Waiting for answer**. Every pending interaction uses an amber warning dot that takes precedence over the running indicator.

+<summary>Implementation internals — click to expand</summary>
+
+The package is one composition: both target slots are declared by other plugins, so `apply` uses `slots.inject()` to register for each declaration lifetime and re-register after a declaring slot is restored.
+
+### The directory-flow hole
+
+Each registration declares a **directory-flow child hole** (`single` kind: `conversation.hero.workspace.directoryFlow` / `sidebar.workspaces.directoryFlow`) that the composed picker package's client half fills with its picking interaction — the `-native` backend's renderless OS-chooser driver, an in-app browsing dialog under a `-browse` composition. The flat **Add workspace...** action renders only while the surface's hole is occupied; an empty hole means the composition has no picking affordance. This package owns the trigger and the adoption: the occupant reports one picked path per open through the hole's owner conversation (`open`/`busy`/`onPicked`/`onCancel`/`onError`), and the owner adopts it through the object layer, selecting the committed Workspace only after its list projection has refreshed.
+
+### View state
+
+Once the Workspace list baseline is ready, browser-persisted expansion and Session-order records retain only current Workspace ids plus Ungrouped and the flat-list account. Real Workspaces initialize from `WorkspaceView.sessionIds`, while Ungrouped and the cross-Workspace flat list initialize from recency. The shared sidebar projection hides rows whose durable Session summary has `origin: 'subagent'`, and each visible ordinary row inherits the blue activity indicator while any descendant reached through uninterrupted subagent-origin lineage is running.
+
+### Hover cards
+
+Workspace and Session hover cards copy the value their row clips: activating a Workspace card writes its full directory path, while activating a non-blank Session card writes its full display title. A provisional blank New Session card remains read-only because its localized label is a placeholder rather than session content.

-共享 Workspace 浏览器与选择器插件。`WorkspaceBrowser` 填充侧边栏的 `sidebar.workspaces` slot，`WorkspacePicker` 则填充页面局部 Session Intent 主视觉区的 `conversation.hero.workspace` slot；两个界面使用同一套 Workspace 菜单和添加流程。
+## 概述
 
-该浏览器通过全局运行时钩子将 Session 行渲染为分组或扁平形式，并负责 Workspace 添加／重命名／重排序以及 Session 重排序。每个 Workspace 会记住自身是关闭还是显示 Session；打开后默认显示五条非空白 Session，当前选中的空白**新会话**在首条提示词落地前作为一条临时额外行保留，其余隐藏条目通过临时的**展开其余**控件显示，而关闭并重新打开整个 Workspace 后会恢复为该折叠投影。从 Workspace 行创建 Session 时会先打开该分组，使 Session 状态到达后新行保持可见。Workspace 列表基线就绪后，浏览器持久化的展开状态与 Session 顺序记录只保留当前 Workspace id、Ungrouped 和单列表记账。视图选项把分组方式和每个记账各自的一份浏览器持久化 Session 顺序放在一起：真实 Workspace 从 `WorkspaceView.sessionIds` 初始化，Ungrouped 和跨 Workspace 的单列表则从最近更新时间顺序初始化。**手动排序**和**最近更新**在两种呈现方式下都可用。进入最近更新时会执行一次完整的时间排序，后续 user prompt 或 steer 会将对应 Session 置顶一次；进入手动排序则保留所有当前位置并停用后续置顶。两种模式下的拖拽都会编辑当前顺序；真实 Workspace 在手动模式下的拖拽还会更新 Host Session 记账，而 Ungrouped 和单列表因没有单一 Workspace 记账，其顺序始终只保存在浏览器本地。折叠分组按当前渲染行确定拖拽边界，并把来源行放在中间隐藏行之前，因此拖动行不会掉入隐藏的剩余项。单列表没有父级层次，因此不显示空的左侧状态槽；Session 存在可见状态时仍保留该槽。无论采用哪种 Session 顺序，Workspace 拖拽顺序都由 Host 持久化。
+`dsh-client-ui-workspace` 是 dsh Web 客户端的共享 Workspace 浏览器与选择器：用户在侧边栏浏览分组或扁平的 Session 行，在 Session Intent 主视觉区为新会话选择 Workspace，并可用添加、重命名、重排序、搜索、fork 与归档操作管理 Workspace 与 Session；两个界面共用同一套 Workspace 菜单与添加流程。待处理的用户交互以琥珀色警告点呈现，共享侧边栏投影会隐藏 subagent 来源的会话。不同的规范化路径仍作为由 id 区分的独立 Workspace；添加文件夹走目录流子 slot，由组合的选择器包 client half 填充。
 
-折叠搜索是视图和添加操作旁的一枚区头按钮。在轨道中，添加和搜索会渲染为沿外壳共用横向进入路径移动的 36px 控件。激活搜索后，输入框会扩展并占据区头；点击外部只会收起经清除首尾空白后为空的查询——但轨道搜索手势仍在进行期间（直至列滑动结束、焦点落入输入框）除外，这样触发展开的那次点击不会收起它刚打开的搜索——而清除控件总会重置并收起搜索。非空白查询会以单一扁平结果列表替代任一浏览模式：不区分大小写的标题和 Workspace 子串匹配项会立即显示，经 250 ms 防抖的 Host 请求则会加入经过排序的当前对话内容匹配项及其摘要片段。英文搜索输入框及其防御性请求路径会移除 NUL，将查询限制在传输 schema 规定的 500 个 UTF-16 代码单元内且不会拆分代理项对，并保留现有的防抖与取消行为。每次新查询都会中止前一个请求；内容搜索失败时，元数据匹配项仍会显示，同时给出警告。列表最多显示 20 条结果，并会在查询过宽时提示用户缩小范围；打开所选 Session 时既不会清除查询，也不会跳转至特定事件。
+## 目录
 
-该选择器通过全局 `useWorkspaces` hook 列出真实的 Host Workspace 实体。选择 Workspace 会调用 slot owner 的 `onPick` 回调，重新定位前端 Session 对象。不同的规范化路径即使 basename 和显示标题相同，仍会作为由 id 区分的独立 Workspace；侧边栏的悬停详情把 POSIX 家目录及其后代显示为 `~`／`~/…`，Windows 路径保持原样。每个注册各自声明一个**目录流子 slot**（`single` kind：`conversation.hero.workspace.directoryFlow`／`sidebar.workspaces.directoryFlow`），由组合的选择器包 client half 填入其选取交互——标准组合使用 [`-native`](../../host/directory-picker-native/README.zh.md) 后端的无渲染 OS 选择器驱动，`-browse` 组合下则是应用内浏览对话框。平铺显示的 **添加工作区…** 操作仅在当前界面的 slot 被占用时渲染（每次菜单渲染读取占用状态；slot 为空意味着该组合没有目录选择能力——seam 文档化的无流程默认行为，此时侧边栏区头直接不渲染添加按钮，而非留下一个点了没反应的按钮）。本包持有触发与接纳：占用方通过 slot 的属主交互约定（`open`/`busy`/`onPicked`/`onCancel`/`onError`）每次打开上报一个所选路径，owner 通过对象层接纳它，并等待 Workspace 列表投影刷新后才选中已提交的 Workspace；取消操作不会显示提示，错误落入可重试的文件夹对话框，其 **重新选择** 会重新打开流程。添加只有一条路径：占用者自带的新建文件夹能力已经覆盖了全新目录，因此不设独立的按名称创建对话框。菜单只在确有多个目标可选时出现——没有 Workspace 可列时，锚点手势直接拉起流程，而不是弹出只有一行的浮层；在列表基线落地前，空列表不算最终结果。运行时 Session 与 Workspace 服务负责物化。Workspace 行内的 Delete 操作会打开确认框，说明保留边界、阻止重复提交，并在失败时保持打开；成功后，该分组会被移除，其 Session 则留在 Ungrouped 下。Session 行内的 Rename 操作打开同款浏览器持有的对话框，并以该行的显示标题预填：客户端不设名称冲突规则（host 负责规范化，可能以 `title-invalid` 拒绝，错误渲染在对话框告警区）；确认未修改的标题是有意允许的——这正是把当前自动标题钉住、使其不被重新生成覆盖的手势。Session 行内的 Archive 操作不经确认对话框直接提交（非破坏性：日志和 workspace 记账席位保持不变），通过 `ctx.workspaces.archiveSession` 归档；归档集合回声落地后，该行从所有分组视图——workspace 分组、Ungrouped、内容搜索和平铺列表——中消失，失败只作为控制台诊断输出，树保持不变。空白的「新会话」行只是占位符：不渲染行菜单和时间标签（其中还没有发生任何事），重命名、fork 和归档都从首条提示词落地后才可用。

-Workspace 和 Session 悬浮卡片会复制对应行被截断的值：激活 Workspace 卡片会写入其完整目录路径，激活非空白 Session 卡片则会写入其完整显示标题。临时的空白「新会话」卡片保持只读，因为其本地化标签是占位文案，并非会话内容。只有浏览器接受剪贴板写入后，卡片才会显示由字典提供的已复制状态。
+-----
 
-Session 行内的 fork 操作在源会话最后一个已完成轮次处 fork，在客户端递增继承的持久化标题后再打开子会话；尾部半角或全角括号编号会原样式递增，无编号标题追加 ` (1)`。源会话与子会话在 workspace 组内始终作为同级行展示，谱系只保留为 session 数据。Fork 或改名失败都不会改变当前选中项，改名失败时已创建的子会话仍会留在列表中。

+## 使用本包
 
-Session 行渲染运行时的实时 `pendingInteraction` 分类：审批显示**等待审批**，计划审阅显示**计划待审**，普通问题显示**等待回答**。每个待处理交互都使用一枚琥珀色警告点，优先级高于运行指示器；普通行的悬浮卡片重复显示本地化状态，普通行和搜索结果行则都以相同文本提供面向辅助技术的视觉隐藏标签。运行状态使用蓝色指示器及其隐藏标签；空闲行会保留空的状态槽位。
+用侧边栏浏览 Workspace 及其 Session、重排它们并新建会话；在 Session Intent 主视觉区用选择器为新会话选择 Workspace。打开的 Workspace 默认显示五条非空白 Session，并在首条提示词落地前把当前选中的空白**新会话**作为一条临时额外行。**展开其余**会显示隐藏条目；关闭再打开 Workspace 会恢复该折叠投影。
 
-两个目标 slot 都由其他插件声明，因此 `apply` 使用 `slots.inject()` 在各自的声明生命周期内完成注册，并在目标 slot 的声明恢复后重新注册。
+### 重排序与视图选项
 
-共享侧边栏投影会隐藏持久化 Session 摘要中带有 `origin: 'subagent'` 的行；用户从所选父级的 subagent 页头目录进入这些对话。每个可见的普通行都会在经不间断的 subagent 谱系可达的任一后代运行时继承蓝色活动指示器；其悬停与无障碍文本会报告确切的运行中后代数量，同时不会把空闲 parent 描述为正在运行。普通 fork 仍然可见，并会终止此聚合，因为仅有谱系不会设置该 origin。待处理的用户交互优先于会话自身的运行中状态，二者无论哪一项存在都会保持为行的主要状态，而后代活动仍作为独立的悬停与无障碍状态保留。两者均不存在时，后代活动优先于绿色的未查看完成提醒；最后一个运行中的后代停止后，该提醒会重新出现。运行时仍保留隐藏行，供对话、标题与已寻址传输状态使用。
+视图选项把分组方式和每个记账各自的一份浏览器持久化 Session 顺序放在一起：**手动排序**和**最近更新**在两种呈现方式下都可用。进入最近更新时会执行一次完整的时间排序，后续 user prompt 或 steer 会将对应 Session 置顶一次；进入手动排序则保留所有当前位置并停用后续置顶。两种模式下的拖拽都会编辑当前顺序；真实 Workspace 在手动模式下的拖拽还会更新 Host Session 记账，而 Ungrouped 和单列表的顺序始终只保存在浏览器本地。折叠分组的拖拽边界按渲染行确定，并把来源行放在中间隐藏行之前，因此拖拽不会隐藏来源行。无论采用哪种 Session 顺序，Workspace 拖拽顺序都由 Host 持久化。
 
+### 搜索

 # @deepseek-ai/dsh-client-web
 
 English | [中文](README.zh.md)
 
-Web boot kernel: `new AppWebEntry(el, seams?).run()` mounts the client through two stages. The module stage calls the Host-installed `window.__ModuleLoader__.create()` with `window.__DSH_BOOT__`, the shell's static modules, and any test transport override; the facade returns the constructed module system and parsed manifest after adopting the parser-loaded bootstrap batch. This package then prefetches the `immediately` tier, whose shared application-batch URL executes once. The plugin stage mounts the vendored Cordis Loader, injects that module system through the Loader's `internal` interface, creates every graph entry uniformly, and waits for every fiber to become ACTIVE. It then hands the marked boot DOM to the dynamic UI renderer's `ctx.uiRenderer.mount(el)` operation; the renderer hydrates that DOM before switching to the complete UI. The Host owns the graph, batch preload, and facade; AppWebEntry does not know the bootstrap package id or parse the wire format.
+## Summary
 
-The boot page uses plain DOM and local CSS, so client-bundle and plugin-activation failures remain visible. Its fallback fonts and colors match the theme tokens that arrive during loading. Fiber updates retain one spinner node and grow its CSS arc as entries first become active; hydration preserves that node and its animation phase until the application commit. React mounting, slot rendering, and application assembly live in [`ui-renderer`](../ui-renderer/README.md); [`ui-layout`](../ui-layout/README.md) owns the assembled browser-title projection. The modules bundle caches its own materialized exports and provides the closed-over system when its ordinary graph entry activates; Cordis service waiting makes graph-row creation order independent from that activation.
+`dsh-client-web` boots the web GUI: it loads the client module system from the Host-provided boot graph, then activates every client plugin before the application mounts, so the full UI appears only when every plugin is up. A framework-free boot page reports per-entry status, so a failing bundle or plugin stays visible instead of a blank screen. It also defines the shared module table (`PLATFORM_MODULES`) that every dynamic bundle resolves its externals against. The model never sees this package.
 
-`PLATFORM_MODULES` (src/platform.ts) is the single source of truth for shell-seeded shared modules. Together with `PRELOADED_CLIENT_EXTERNALS`, it defines the implicit external baseline for every dynamic bundle; `dsh.client.external` adds only exact non-baseline requests.
+## Table of Contents
 
-The optional override parameter `seams` forwards the module system's `loadBundle` transport override (`BootSeams`) for environments where external `<script>` execution cannot reach the page context; ordinary browser callers omit it. A pre-injected page transport is the default ahead of it: when `globalThis.__DSH_TRANSPORT__` (the connection package's `ClientTransportHooks`) carries `loadBundle`, the module stage adopts it as the bundle transport and skips the immediate-tier HTTP prefetch — explicit `seams` still win.

+## Use this package
+
+Use it when you assemble the browser application: `apps/web`'s Vite entry runs `new AppWebEntry(container).run()` against the mount point, and the boot page carries the user through activation. Ordinary browser callers pass no options. A pre-injected page transport is the default ahead of the `seams` override: when `globalThis.__DSH_TRANSPORT__` carries `loadBundle`, the module stage adopts it as the bundle transport and skips the immediate-tier HTTP prefetch, while explicit `seams` still win (for example jsdom tests, where external `<script>` execution cannot reach the page context).
+
+### What boot looks like
+
+Boot runs in two stages: the module stage adopts the parser-loaded bootstrap batch, builds the module system from the Host-provided boot graph, and prefetches the `immediately` tier through the shared application-batch URL, which executes once. The plugin stage then activates every graph entry and waits for all of them before handing the marked boot DOM to the UI renderer, which hydrates it and switches to the complete UI.
+
+### The boot page
+
+The boot page uses plain DOM and local CSS, so bundle and plugin-activation failures remain visible: it shows one spinner node whose CSS arc grows as entries activate, and reports per-entry status. The spinner and its animation phase persist until the full UI replaces the boot page. A plugin that fails import or activation is reported by name with the reason (missing service, import error, or state) instead of a blank page.
+
+### The shared module table
+
+`PLATFORM_MODULES` (in `src/platform.ts`) names the shell-seeded shared modules — React, Cordis, and static UI libraries — and together with `PRELOADED_CLIENT_EXTERNALS` (the parser-preloaded runtime row) defines the implicit external baseline every dynamic bundle resolves against. `dsh.client.external` adds only exact non-baseline requests; see [shared modules and the module graph](../AGENTS.md#shared-modules-and-the-module-graph).
+
+### Configuration
+
+The package accepts no plugin config of its own; the generated [configuration catalog](../../../docs/config-catalog.md) lists every plugin config in the repo for comparison.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the boot kernel is built; observable behavior is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The kernel owns exactly three things: the module system, the Cordis Loader, and the boot page. The Host owns the graph, batch preload, and loader facade, so `AppWebEntry` never knows the bootstrap package id or parses the wire format. The dynamic UI renderer receives the mount point only after every client entry activates.
+
+### Two-stage boot
+
+`run()` calls the Host-installed `window.__ModuleLoader__.create({ boot, staticModules, ...seams })`; the facade returns the constructed module system and parsed manifest after adopting the parser-loaded bootstrap batch. The module stage prefetches the `immediately` tier through the one shared application-batch URL. The plugin stage mounts the Loader, assigns `loader.internal = modules`, creates every graph entry uniformly, awaits quiescence, then audits activation: any entry that failed import, stayed pending on a missing service, or landed in another non-active state throws one aggregated error naming every failing entry.
+
+### Boot page mechanics
+
+The boot page is plain DOM with local CSS whose fallback fonts and colors match the theme tokens that arrive during loading. `internal/status` events drive one spinner node and per-entry labels; hydration preserves the node and animation phase through the application commit, and `fail()` renders the thrown reason. React mounting, slot rendering, and assembly live in `ui-renderer`; `ui-layout` owns the assembled browser-title projection.

-Web 启动内核：`new AppWebEntry(el, seams?).run()` 分两个阶段挂载客户端。模块阶段调用 Host 安装的 `window.__ModuleLoader__.create()`，传入 `window.__DSH_BOOT__`、外壳静态模块以及可选测试传输覆盖；facade 接纳 parser 已加载的 bootstrap 批次后返回构造好的模块系统与已解析 manifest。本包随后预取 `immediately` 层级，其共享的 application 批次 URL 只执行一次。插件阶段挂载仓库内置的 Cordis Loader，通过 Loader 的 `internal` 接口注入该模块系统，统一创建全部图 entry，并等待每个 fiber 进入 ACTIVE。随后它把带标记的启动 DOM 交给动态 UI 渲染器的 `ctx.uiRenderer.mount(el)` 操作；渲染器先 hydrate 该 DOM，再切换到完整 UI。Graph、批次 preload 与 facade 归 Host 所有；AppWebEntry 不感知 bootstrap package id，也不解析 wire 格式。
+## 概述
 
-启动页只使用原生 DOM 与本地 CSS，因此客户端 bundle 或插件激活失败时仍能显示。其回退字体和颜色与加载期间到达的主题 token 一致。fiber 更新会保留同一个 spinner 节点，并在 entry 首次进入 active 时增长其 CSS 圆弧；hydrate 会继续保留该节点及其动画相位，直到应用提交。React 挂载、slot 渲染和应用组装位于 [`ui-renderer`](../ui-renderer/README.zh.md)；[`ui-layout`](../ui-layout/README.zh.md) 拥有组装后的浏览器标题投影。Modules bundle 会缓存自身已物化导出，并在其普通图 entry 激活时提供闭包中的系统；Cordis service 等待使图 row 创建顺序不依赖该激活时点。
+`dsh-client-web` 启动 web GUI：它先从 Host 提供的启动图加载客户端模块系统，再在应用挂载前激活每一个客户端插件，因此只有当所有插件都就绪时完整 UI 才会出现。无框架启动页会逐 entry 报告状态，因此失败的 bundle 或插件保持可见，而不是白屏。它还定义共享模块表（`PLATFORM_MODULES`），每个动态 bundle 都依据它解析 external。模型永远看不到本包。
 
-`PLATFORM_MODULES`（src/platform.ts）是外壳播种共享模块的唯一事实来源。它与 `PRELOADED_CLIENT_EXTERNALS` 一起定义全部动态 bundle 的隐式 external 基座；`dsh.client.external` 只添加基座之外的精确请求。
+## 目录
 
-可选的覆盖参数 `seams` 会为外部 `<script>` 执行无法到达页面上下文的环境转发模块系统的 `loadBundle` 传输覆盖（`BootSeams`）；普通浏览器调用方省略此参数。预注入的页面传输是位于其前的默认值：当 `globalThis.__DSH_TRANSPORT__`（connection 包的 `ClientTransportHooks`）携带 `loadBundle` 时，模块阶段将其采纳为 bundle 传输并跳过 immediately 层级的 HTTP 预取——显式 `seams` 仍然优先。

+## 使用本包
+
+组装浏览器应用时使用它：`apps/web` 的 Vite 入口对挂载点运行 `new AppWebEntry(container).run()`，启动页承载用户度过激活过程。普通浏览器调用方不传任何选项。预注入的页面传输是 `seams` 覆盖之前的默认：当 `globalThis.__DSH_TRANSPORT__` 携带 `loadBundle` 时，模块阶段将其采纳为 bundle 传输并跳过 `immediately` 层级的 HTTP 预取，而显式 `seams` 仍然优先（例如外部 `<script>` 执行无法到达页面上下文的 jsdom 测试）。
+
+### 启动过程是怎样的
+
+启动分两个阶段：模块阶段接纳 parser 已加载的 bootstrap 批次，从 Host 提供的启动图构建模块系统，并通过只执行一次的共享 application 批次 URL 预取 `immediately` 层级。插件阶段随后激活每个图 entry 并等待全部就绪，之后才把带标记的启动 DOM 交给 UI 渲染器，由它 hydrate 并切换到完整 UI。
+
+### 启动页
+
+启动页只使用原生 DOM 与本地 CSS，因此 bundle 与插件激活失败保持可见：它显示一个 spinner 节点，其 CSS 圆弧随 entry 激活而增长，并逐 entry 报告状态。spinner 及其动画相位会一直保留，直到完整 UI 替换启动页。导入或激活失败的插件会按名称报告并给出原因（缺失服务、导入错误或状态），而不是白屏。
+
+### 共享模块表
+
+`PLATFORM_MODULES`（位于 `src/platform.ts`）列出外壳播种的共享模块——React、Cordis 与静态 UI 库——并与 `PRELOADED_CLIENT_EXTERNALS`（parser 预载的 runtime 行）一起定义每个动态 bundle 解析所依据的隐式 external 基座。`dsh.client.external` 只添加基座之外的精确请求；参见[共享模块与模块图](../AGENTS.md#shared-modules-and-the-module-graph)。
+
+### 配置
+
+本包自身不接受任何插件配置；生成的[配置目录](../../../docs/config-catalog.zh.md)列出仓库中每个插件配置以供对照。

+<summary>实现细节——点击展开</summary>
+
+本节解释启动内核的构建方式；可观察行为已在[使用本包](#use-this-package)中说明。
+
+### 设计理念
+
+内核恰好拥有三样东西：模块系统、Cordis Loader 与启动页。Graph、批次 preload 与 loader facade 归 Host 所有，因此 `AppWebEntry` 永不感知 bootstrap package id，也不解析协议格式。动态 UI 渲染器只在每个客户端 entry 激活后收到挂载点。
+
+### 两阶段启动
+
+`run()` 调用 Host 安装的 `window.__ModuleLoader__.create({ boot, staticModules, ...seams })`；facade 接纳 parser 已加载的 bootstrap 批次后返回构造好的模块系统与已解析 manifest。模块阶段通过一个共享的 application 批次 URL 预取 `immediately` 层级。插件阶段挂载 Loader、把 `loader.internal` 赋为 `modules`、统一创建全部图 entry、等待完全停稳，然后审计激活：任何导入失败、因缺失服务而 pending，或落入其他非 active 状态的 entry，都会抛出一个聚合错误，点名每个失败 entry。
+
+### 启动页机制
+
+启动页是原生 DOM 加本地 CSS，其回退字体与颜色匹配加载期间到达的主题 token。`internal/status` 事件驱动一个 spinner 节点与逐 entry 标签；hydrate 会保留该节点与动画相位直到应用提交，`fail()` 渲染抛出的原因。React 挂载、slot 渲染与应用组装位于 `ui-renderer`；`ui-layout` 拥有组装后的浏览器标题投影。

 # code-runtime/ — code-execution capability family
 
 English | [中文](README.zh.md)
 
-The code-execution capability seam (see [capability seams](../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.md)): a runtime Service Definition for executing one model-written program against host-provided async bindings, capturing what it printed and returned; replaceable providers; and the tool registry's [Code Mode](../core/tools/README.md) Consumer (`tools: { mode: code }` — the `run_code` tool and the SDK generated in the loaded runtime's `language`). Design is in the [Code Mode Agent Note](../../.agents/notes/implemented/feature/2026-06-15-code-mode.md). **Product** packages.
+## Summary
+
+The `code-runtime/` group provides program execution: a model writes one program that calls host-provided functions as ordinary async calls, and a runtime executes it in isolation and returns only what the program printed and returned. One package defines the shared capability (`ctx.codeRuntime`), a second executes TypeScript programs in a fresh Node worker thread, and a third owns the wire protocol between a Node host and a CPython subprocess for the Python backend. Every run is independent — no state carries from one program to the next — and failures come back as part of the result, so the caller can see why a program failed and feed that back to the model.

-CPython-subprocess implementation of the [`@deepseek-ai/dsh-code-runtime`](../code-runtime/README.md) seam. Companion to [`@deepseek-ai/dsh-code-runtime-worker-thread`](../code-runtime-worker-thread/README.md); trades the Node worker thread for a fresh `python3` subprocess so model code is Python instead of TypeScript.
+## Summary
 
-The package owns the wire protocol for that seam: the host-side frame codec and the Python-side mirror of the same message vocabulary.
+`dsh-code-runtime-python` owns the versionless wire protocol between a Node host and a CPython subprocess for the [`dsh-code-runtime`](../code-runtime/README.md) seam: one JSON object per line on the child's fd 3, leaving stdout/stderr free for the program's own output. The package ships the host-side frame codec and hostile-frame validators (`src/protocol.ts`) plus the Python-side mirror of the same message vocabulary (`py/protocol.py`), so every consumer of the wire shares one vocabulary. It is the protocol layer for the Python backend — the package carries no subprocess execution path, so nothing here spawns `python3` outside the cross-language mirror test. The host treats every inbound frame as hostile, because model code has full access to fd 3 and can post anything through it.

-- **fd 3, not stdout** — Node pins the channel positionally with `stdio: ['pipe','pipe','pipe','pipe']`; the Python bootstrap reads the same `PROTOCOL_FD` constant. JSON-lines framing.
-- **Host treats every inbound frame as hostile** — model code has full access to fd 3 and can post anything through it, so `validateChildFrame` shape-validates and REBUILDS each frame before the host reads it: forged extra fields never ride along, a non-number call id can never be echoed into a reply, and junk drops to `undefined` rather than throwing in the host's message handler. The Python side trusts host replies (the host is not model-controlled).
-- **Lossless-JSON crossing** — completion values and binding arguments cross as exact JSON. `encodeJsonPlain` serializes a `JSON.parse`-produced value without recursion, so a deep value below the byte budget crosses intact instead of dying on `JSON.stringify`'s stack limit; `checkDoneValue` meters a forged completion value's byte length AND number losslessness in one traversal that rejects an over-budget payload before the incremental work it would add (the enqueued children; strings and keys are metered by a non-allocating escaped-size scan, so the escaped copy is never materialized) — the frame's own width is already parsed and capped upstream by the host's fd-3 receive buffer, not re-bounded here; `hasUnsafeIntegerToken` reads the raw frame text to catch an integer token that `JSON.parse` would silently round; `hasNonLosslessNumber` rejects a non-finite or negative-zero number in unbounded `call.args`. Beyond-safe-range integral doubles serialize through `BigInt` digits so the exact integer crosses, not the rounded `String()` form.
-- **Shared truncation marker** — `logTruncationMarker(maxBytes)` produces byte-identical text on both sides, so a truncated log run reads the same however the cap was hit. The `log` frame's `truncated` flag distinguishes the child ledger's own marker from program output.

+<a id="use-this-package"></a>
+## Use this package
+
+Choose this package when you build or consume the CPython code-runtime wire: implement the Python backend or the host that drives it, or debug a Python code run's framing. The package is the wire protocol intended for a CPython code-runtime provider — such a provider runs each model program in a fresh `python3 -I` subprocess — and this package supplies the protocol both sides speak, so its exports are the single TS-side source of truth for the wire.
+
+### What you get
+
+The package re-exports the host-side protocol vocabulary from `src/index.ts`: `validateChildFrame` (rebuilds every inbound frame before the host reads it), the lossless-JSON codec and meters (`encodeJsonPlain`, `checkDoneValue`, `hasUnsafeIntegerToken`, `hasNonLosslessNumber`), and `logTruncationMarker` (the shared truncation-marker text). The Python side mirrors the message shapes as `TypedDict`s in `py/protocol.py` and re-declares the two surfaces both sides execute against — `PROTOCOL_FD = 3` and the marker text.
+
+### The wire
+
+Frames travel on the child's fd 3 as JSON-lines — one object per line — so stdout/stderr stay clear for the program's own output. Child → host: `boot-ack`, `call`, `log`, `done`. Host → child: `boot` (first frame, carrying every cap and the namespace declarations), `run` (after `boot-ack`, carrying only the program body), and one `reply` per `call`. A forged frame can carry both `value` and `error` on `done`, so a consumer must check `error` first and ignore `value` when it is set.
+
+### What can go wrong
+
+Host-side validation drops junk without throwing, so a malformed or forged frame never crashes the host process: `validateChildFrame` returns `undefined` for anything that does not rebuild cleanly, a non-number call id can never be echoed into a reply, and forged extra fields never ride along. A completion value that is not lossless JSON, or that exceeds the configured byte budget, is rejected explicitly (`non-lossless` / `over-budget`) rather than silently rounded or truncated.
+

+
+<a id="understand-the-implementation"></a>
+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design behind the wire protocol; observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The protocol assumes one direction of trust: the host treats every inbound frame as hostile (model code can forge anything on fd 3) and REBUILDS it field by field before reading; the Python side trusts host replies, because the host is not model-controlled. The package is deliberately the protocol layer only — the Python-side JSON codec lives in the backend's bootstrap, not in `py/protocol.py`, so the mirror stays the pure wire-vocabulary counterpart of `src/protocol.ts`.
+
+### Wire contract
+
+The frames are `boot` / `run` (host → child) and `boot-ack` / `call` / `log` / `done` plus one `reply` per call (child → host). The `log` frame's `truncated` flag marks the frame that IS the child ledger's truncation marker, so the host stops capturing at the same point the child did instead of inferring it from its own budget. `done.error.kind` is one of `exception`, `invalid-output`, `output-limit`; wall/CPU budgets, aborts, and substrate death are observed host-side, not carried as frames.
+
+### Lossless JSON crossing
+
+Completion values and binding arguments cross as exact JSON: values serialize without recursion, so a deep payload below the byte budget survives instead of dying on `JSON.stringify`'s stack limit, and integral doubles beyond the safe range cross as exact digits rather than silently rounded tokens; the meters in [`src/protocol.ts`](src/protocol.ts) enforce byte budgets and number losslessness before anything else reads the payload.
+
+### Mirror alignment
+
+`tests/protocol-mirror.e2e.ts` spawns a real `python3` and asserts, against `src/protocol.ts`, both `PROTOCOL_FD` / the truncation-marker text and each `TypedDict`'s required/optional wire field set in `py/protocol.py`, so a renamed or dropped field — or one side making a field optional the other requires — fails the test. Field *types* are not compared across the language boundary; that residue stays with review plus the backend's real-subprocess suite.

 ## Known Limitations and Deferred Work
 
-- **The cross-language guard covers the runtime-executed surfaces and the frame field shapes** — `tests/protocol-mirror.e2e.ts` spawns a real `python3` and asserts, against `src/protocol.ts`, both `PROTOCOL_FD` / the log truncation marker text AND each `TypedDict`'s required/optional wire field set in `py/protocol.py`. What it does not compare is the field *types* (e.g. that `cpuSeconds` is an `int` on both sides): comparing type declarations across TypeScript and Python has no mechanical equivalent here, so a type-level drift is still caught by review plus the backend's real-subprocess suite rather than this package's tests.

-- **host 把每个入站帧当作敌意输入** —— 模型代码对 fd 3 有完全访问权、可通过它发送任意内容，所以 `validateChildFrame` 在 host 读取前对每个帧做形状校验并重建：伪造的额外字段绝不随行，非数字的 call id 绝不会被回显进 reply，垃圾降为 `undefined` 被丢弃，而不是在 host 的 message handler 里抛错。Python 侧信任 host 回复（host 不受模型控制）。
-- **lossless-JSON 穿越** —— 完成值与 binding 参数以精确 JSON 穿越。`encodeJsonPlain` 无递归地序列化一个 `JSON.parse` 产出的值，使低于字节预算的深层值能完整穿越，而不是死在 `JSON.stringify` 的栈限制上；`checkDoneValue` 在一次遍历中同时计量伪造完成值的字节长度与数字无损性，在它本会新增的增量工作之前就拒绝超预算 payload（即入栈子节点；字符串与 key 由非分配的转义尺寸扫描计量，从不物化转义副本）——帧自身的宽度已被上游 `JSON.parse` 支付、由 host 的 fd-3 接收缓冲封顶，并非在此重新约束；`hasUnsafeIntegerToken` 读取原始帧文本，捕获 `JSON.parse` 会静默舍入的整数 token；`hasNonLosslessNumber` 拒绝无字节上限的 `call.args` 中的非有限数或负零。超出安全范围的整数型 double 通过 `BigInt` 数字序列化，穿越的是精确整数而非 `String()` 的舍入形式。
-- **共享截断标记** —— `logTruncationMarker(maxBytes)` 在两侧产出逐字节一致的文本，使被截断的日志运行无论从哪侧触达上限都读起来一致。`log` 帧的 `truncated` 标志把子进程 ledger 自身的标记与程序输出区分开。

+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释协议格式（wire protocol）背后的设计；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+协议假定单向信任：host 把每个入站帧都当作敌意输入（模型代码可以在 fd 3 上伪造任何内容），并在读取前逐字段重建；Python 侧信任 host 回复，因为 host 不受模型控制。本包刻意只是协议层——Python 侧 JSON codec 位于后端的 bootstrap 中，而非 `py/protocol.py`，因此镜像保持为 `src/protocol.ts` 的纯 wire 词汇对侧。
+
+### 协议约定
+
+帧为 `boot`／`run`（host → 子进程）与 `boot-ack`／`call`／`log`／`done` 加每个 call 一个 `reply`（子进程 → host）。`log` 帧的 `truncated` 标志标记「就是子进程 ledger 截断标记」的那个帧，因此 host 在子进程停下的同一点停止捕获，而不是根据自己的预算推断。`done.error.kind` 是 `exception`、`invalid-output`、`output-limit` 之一；墙钟／CPU 预算、中止与基底终止在 host 侧观测，不作为帧携带。
+
+### 无损 JSON 穿越
+
+完成值与 binding 参数以精确 JSON 穿越：值无递归地序列化，因此低于字节预算的深层 payload 能完整穿越，而不是死在 `JSON.stringify` 的栈限制上；超出安全范围的整数型 double 以精确数字穿越，而不是被静默舍入的 token；[`src/protocol.ts`](src/protocol.ts) 中的计量器在任何其他代码读取 payload 之前强制执行字节预算与数字无损性。
+
+### 镜像对齐
+
+`tests/protocol-mirror.e2e.ts` 启动一个真实 `python3`，对照 `src/protocol.ts` 断言 `PROTOCOL_FD`／截断标记文本，以及 `py/protocol.py` 中每个 `TypedDict` 的必填/可选 wire 字段集，因此重命名或删除字段——或一侧把另一侧必填的字段改为可选——都会让测试失败。跨语言边界不比较字段*类型*；该残留由 review 加后端的真子进程套件负责。

-Worker-thread implementation of the [`@deepseek-ai/dsh-code-runtime`](../code-runtime/README.md) seam: `WorkerThreadCodeRuntime` runs each program in ONE fresh Node `worker_threads.Worker` — TypeScript in, type-stripped host-side, bindings bridged over the message port, `{ value, logs, error? }` out. **Containment, not a security boundary**: trust posture is bash-equivalent by design (the [Code Mode Agent Note](../../../.agents/notes/implemented/feature/2026-06-15-code-mode.md) § Trust posture), with containment bash does not have — separate isolate, empty environment, heap cap, hard termination.
+## Summary
 
-## Config
+`dsh-code-runtime-worker-thread` executes TypeScript programs for the [`dsh-code-runtime`](../code-runtime/README.md) seam: each program runs in one fresh Node worker thread with host-provided bindings callable as ordinary async functions, and the run returns `{ value, logs, error? }`. It is the shipped backend for Code Mode in `dsh-tools`, so mounting it is what makes model-written TypeScript execution work in a composition. The runtime contains a program without isolating it: the trust posture is bash-equivalent, with an empty environment, a heap cap, measured busy-time and wall-clock budgets, and hard termination. Programs run once per request with no state carried between runs, and every failure — syntax error, budget expiry, abort, OOM exit, or output overflow — comes back as a result field.

+## Use this package
+
+Mount this backend with the code-runtime seam when a composition should execute model-written TypeScript programs; Code Mode in `dsh-tools` then drives it through `ctx.codeRuntime` whenever the model calls `run_code`. Every execution cap is validated config, so you can size the runtime for your deployment from `cordis.yml`.
+
+### Minimal configuration
 
 ```yaml
-- id: code-runtime
-  name: '@deepseek-ai/dsh-code-runtime-worker-thread'
+- name: '@deepseek-ai/dsh-code-runtime'
+- name: '@deepseek-ai/dsh-code-runtime-worker-thread'
   config:
-    computeMs: 60000              # busy-time budget (measured event-loop active time)
-    maxWallMs: 600000             # wall-clock ceiling; never pauses for anything
-    maxOutputBytes: 67108864      # combined serialized outer-output cap (64 MiB)
-    maxOldGenerationSizeMb: 512   # worker heap cap (resourceLimits)
+    computeMs: 60000            # busy-time budget (measured event-loop active time)
+    maxWallMs: 600000           # wall-clock ceiling; never pauses for anything
+    maxOutputBytes: 67108864    # combined serialized outer-output cap (64 MiB)
+    maxOldGenerationSizeMb: 512 # worker heap cap
 ```
 
-Every field is validated and defaulted; `maxOutputBytes` is a safe integer of at least four bytes, the remaining fields are positive finite numbers, `maxWallMs` is additionally at most `2147483647` (Node's maximum `setTimeout` delay), and there are no other tunables.
+| Field | Default | Meaning |
+|---|---|---|
+| `computeMs` | `60,000` | Busy-time budget: the run fails with `timeout` once the worker's measured event-loop active time exceeds it |
+| `maxWallMs` | `600,000` | Wall-clock ceiling, the backstop for waits that busy time cannot see; at most `2_147_483_647` |
+| `maxOutputBytes` | `67,108,864` | Hard cap for serialized logs plus the completion value or failure message; at least `4` |
+| `maxOldGenerationSizeMb` | `512` | Worker heap cap; overflow kills the worker and surfaces as `worker-exit` |
 
-## Design
+Every field is validated and defaulted at load; there are no other tunables. The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-code-runtime-worker-thread) is the exhaustive source for every accepted field.
 
-- **One fresh worker per run, no pooling** — a program's world dies with its worker: no cross-run state to log, state bleed unrepresentable, runs reconstructable from the session log alone.
-- **Type-strip host-side, in execution context** — the program is wrapped in an async-function shell, stripped with `node:module`'s `stripTypeScriptTypes` (erasable syntax only — `enum`/namespaces are rejected as a program `exception` and no worker spawns), and sliced back out byte-positioned; it then executes as the body of an `AsyncFunction`, so top-level `await`/`return` work.
-- **The port assumes a hostile peer** — model code can reach `parentPort` and forge traffic, so every inbound message is shape-validated and REBUILT before anything reads it (`null`, primitives, junk types, and malformed payloads drop without a throw; forged extra fields never ride along), the host answers each call id at most once, resolves binding names as OWN properties only (a forged `constructor` cannot walk a prototype chain), drops post-settlement replies, and validates every binding resolution and completion as lossless JSON. Forged `log`/`done` messages cannot bypass the outer cap: the host repeats validation and accounts every admitted log plus the completion or diagnostic. Worker-side namespaces are null-prototype with `defineProperty`, so `__proto__`-shaped binding names are ordinary keys.
-- **Binding rejection classes are request data** — an optional namespace descriptor names the constructor global and the own property that receives the failed member name. The worker materializes and injects that real class, so `instanceof` works without hardcoding `tools` or `ToolCallError`; declarations with invalid or colliding globals fail before a worker spawns. Failures use module-captured error and property-definition intrinsics plus null-prototype descriptors, so later model mutations cannot turn a rejected binding into a worker crash.
-- **Two independent budgets, because the peer is hostile** — `computeMs` meters the worker's MEASURED busy time (`worker.performance.eventLoopUtilization()` polling): a hot loop cannot hide behind a pending decoy dispatch, and a program awaiting a slow tool accrues nothing. `maxWallMs` backstops what busy time cannot see (awaiting a promise nobody resolves). Both funnel into `worker.terminate()`, which ends hot synchronous loops too; heap overflow surfaces as the worker's OOM exit (`kind: 'worker-exit'`). `maxWallMs` is range-checked at load against `MAX_TIMER_DELAY_MS`: `setTimeout` clamps a longer delay to 1 ms, so a positivity check alone would accept a ceiling that expires on the first tick. `computeMs` needs no such bound, being compared against measured utilization rather than fed to a timer.
-- **Intermediate binding values are complete JSON** — binding arguments and resolutions undergo lossless-JSON validation and transfer without a byte cap. The worker captures the validation primitives before executing untrusted code, so mutations to globals or prototypes cannot weaken validation or byte accounting. Intermediate values never enter the outer-output ledger or model context; provider/executor acquisition bounds and process/worker memory remain the limits.
-- **Logs stream eagerly into one outer ledger** — console/stdout/stderr text crosses the port in emission order, so a timed-out or killed program still shows what it printed. The worker charges exact JSON-string bytes and preflights completion values and exception diagnostics against the remaining combined budget before posting them; a thrown million-byte stack therefore becomes the fixed `output-limit` diagnostic at the worker boundary. Native writes that bypass the patched stream slots arrive on pipes independent of the completion port, so the host repeats the ledger for those bytes and hostile forged traffic; settlement continues bounded pipe capture until worker termination completes before materializing the result. `maxOutputBytes` accounts the JSON serialization of the outer `logs` array plus the completion value or failure-message payload; fixed `CodeRunResult` field names, braces, the bounded error-kind tag, and later presentation whitespace are outside that variable-payload ledger. At or below the cap the exact value returns; a lossy completion is `invalid-output`, and a combined overflow is `output-limit` rather than a substituted inspected string. The failure retains the fitting captured prefix and later follows the normal outer `run_code` spill policy.
-- **Empty environment** — the worker gets `env: {}` and `execArgv: []`: no ambient credentials (stronger than the scrubbed-env rule for spawned commands) and no inherited loader flags.
-- **Dispose to quiescence** — teardown fails in-flight runs as `abort` and AWAITS each worker's exit before resolving.
+### What a run returns
 
-## The worker entry, unbuilt and built
+A successful run returns the program's lossless-JSON completion value as `result.value` and the text it printed, in order, as `result.logs`. Top-level `await` and `return` work, and the program can call the host-provided binding functions (Code Mode exposes one `tools` object) as ordinary async calls.
 
-Source mode loads erasable-only `src/worker.ts` through Node's native type stripping. Its transitive runtime closure contains only Node built-ins and relative source modules, so a fresh checkout never requires a sibling workspace package's unbuilt `lib/` export. The worker-local and session-owned JSON boundaries both flatten and rebuild validated values around the message port so application nesting never reaches structured clone. Built mode passes the sibling `lib/worker.cjs` as a filesystem path because pkg's VFS Worker hook expects CommonJS; the same path works under ordinary Node. The repository-wide requirement to exercise this published entry path belongs to the [testing policy](../../../docs/testing.md).
+### Containment, not a security boundary
 
-The SDK API is the default/named `WorkerThreadCodeRuntime` class plus `Config`. The operational `./worker` subpath exists only as the packaged spawn entry; the wire protocol and bootstrap helpers are source-private implementation details.
+A program runs with authority comparable to the bash tool: it can reach Node APIs, and the backend deliberately does not promise isolation from the host. What it does provide is containment — a separate isolate, an empty environment (no ambient credentials, no inherited loader flags), a configurable heap cap, and hard termination that also stops a hot synchronous loop. OS processes a program spawns survive `terminate()` and need deployment-level cleanup.
 
+### What can go wrong
+
+Every program outcome resolves as a result, so a failed run is a `result.error`, not a rejection: a syntax error or non-erasable TypeScript (`enum`, namespaces) fails as `exception` before any worker spawns; budget expiry is `timeout`; the abort signal is `abort`; a heap overflow or other worker death is `worker-exit`; a completion value that is not lossless JSON is `invalid-output`; and serialized output beyond the cap is `output-limit` — with the fitting captured log prefix retained. Rejection means caller misuse, such as a run submitted after disposal.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design behind the backend; observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The backend rests on one separation: **containment, not a security boundary**. Model code has bash-equivalent trust (the [Code Mode Agent Note](../../../.agents/notes/implemented/feature/2026-06-15-code-mode.md) Trust posture), so the design optimizes for reconstructability and bounded resource use rather than for a hard multi-tenant boundary — that awaits a container-class backend. Each run gets one fresh worker, so a program's world dies with its worker: no cross-run state exists to leak or to log, and a run is reconstructable from the session log alone.

+### Execution flow

+A run is type-stripped host-side (`node:module`'s `stripTypeScriptTypes`, position-preserving), wrapped as the body of an async function so top-level `await`/`return` work, and sent to a fresh worker whose bootstrap materializes the binding namespaces. Binding calls cross the message port as lossless JSON and are answered at most once per call id. Log text streams to the host eagerly so a killed program still shows what it printed. Exactly one outcome settles the run — a `done` frame, a budget expiry, an abort, or worker death — after which the host terminates the worker and awaits its exit.
+
+### Hostile-peer port
+
+Model code can reach `parentPort` and forge traffic, so every inbound message is shape-validated and rebuilt field by field before anything reads it: forged extra fields never ride along, a non-number call id can never be echoed into a reply, binding names resolve as own properties only (a forged `constructor` cannot walk a prototype chain), and junk drops silently. Worker-side namespaces are null-prototype, so `__proto__`-shaped binding names are ordinary keys.
+
+### Budgets
+
+Two independent budgets exist because the peer is hostile: `computeMs` meters the worker's measured busy time (`eventLoopUtilization()` polling every 25 ms), so a hot loop expires it whether or not a decoy dispatch is in flight, while a program idling on a slow binding accrues nothing; `maxWallMs` backstops what busy time cannot see, such as a promise nobody resolves. Both funnel into `worker.terminate()`. `maxWallMs` is range-checked at load against `MAX_TIMER_DELAY_MS` because `setTimeout` clamps a longer delay to 1 ms.
+
+### Output ledger
+
+`maxOutputBytes` accounts the JSON serialization of the outer `logs` array plus the completion value or failure-message payload; fixed `CodeRunResult` field names and envelope syntax are outside that ledger. At or below the cap the exact value returns; a lossy completion is `invalid-output`, and a combined overflow is `output-limit` rather than a substituted inspected string. The failure retains a fitting captured prefix of the logs.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `Config` schema, `WorkerThreadCodeRuntime`, run orchestration, output ledger |
+| [`src/worker.ts`](src/worker.ts) | Source-mode worker entry (erasable TypeScript, no `lib/` dependency) |
+| [`src/bootstrap.ts`](src/bootstrap.ts) | Worker-side bootstrap: namespace materialization, console shim, log capture |
+| [`src/protocol.ts`](src/protocol.ts) | Port message vocabulary between host and worker |

+| [`src/output-json.ts`](src/output-json.ts) | Byte metering and truncation for the outer ledger |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; see its reason) |
+
+### The worker entry, unbuilt and built
+
+Source mode loads erasable-only `src/worker.ts` through Node's native type stripping; its transitive runtime closure contains only Node built-ins and relative source modules, so a fresh checkout never requires a sibling workspace package's unbuilt `lib/` export. Built mode passes the sibling `lib/worker.cjs` as a filesystem path because pkg's VFS Worker hook expects CommonJS; the same path works under ordinary Node.

-这是 [`@deepseek-ai/dsh-code-runtime`](../code-runtime/README.zh.md) seam 的 worker 线程实现：`WorkerThreadCodeRuntime` 会在每次运行中使用一个全新的 Node `worker_threads.Worker`，输入 TypeScript，由宿主侧剥离类型，通过消息端口桥接绑定，输出 `{ value, logs, error? }`。**这是隔离措施，而非安全边界**：其信任立场有意与 bash 等价（参见 [Code Mode Agent Note](../../../.agents/notes/implemented/feature/2026-06-15-code-mode.zh.md) 的 Trust posture 章节），但提供 bash 没有的隔离：独立 isolate、空环境、堆上限与强制终止。
+## 概述
 
-## 配置
+`dsh-code-runtime-worker-thread` 为 [`dsh-code-runtime`](../code-runtime/README.zh.md) seam 执行 TypeScript 程序：每个程序都在一个全新的 Node Worker 线程中运行，宿主提供的绑定可作为普通异步函数调用，运行返回 `{ value, logs, error? }`。它是 `dsh-tools` 中 Code Mode 的已发布后端，因此挂载它正是让模型编写的 TypeScript 执行在组合中生效的方式。运行时「包含」程序，但不隔离它：信任立场与 bash 等价，并带有空环境、堆上限、实测忙碌时间与墙钟预算，以及强制终止。程序每次请求只运行一次，运行之间不保留状态；每个失败——语法错误、预算到期、中止、OOM 退出或输出溢出——都以结果字段返回。

+## 使用本包
+
+当组合需要执行模型编写的 TypeScript 程序时，连同 code-runtime seam 一起挂载此后端；只要模型调用 `run_code`，`dsh-tools` 中的 Code Mode 就会通过 `ctx.codeRuntime` 驱动它。每个执行上限都是已验证的配置，因此你可以从 `cordis.yml` 为部署调整运行时规模。
+
+### 最小配置
 
 ```yaml
-- id: code-runtime
-  name: '@deepseek-ai/dsh-code-runtime-worker-thread'
+- name: '@deepseek-ai/dsh-code-runtime'
+- name: '@deepseek-ai/dsh-code-runtime-worker-thread'
   config:
-    computeMs: 60000              # busy-time budget (measured event-loop active time)
-    maxWallMs: 600000             # wall-clock ceiling; never pauses for anything
-    maxOutputBytes: 67108864      # combined serialized outer-output cap (64 MiB)
-    maxOldGenerationSizeMb: 512   # worker heap cap (resourceLimits)
+    computeMs: 60000            # busy-time budget (measured event-loop active time)
+    maxWallMs: 600000           # wall-clock ceiling; never pauses for anything
+    maxOutputBytes: 67108864    # combined serialized outer-output cap (64 MiB)
+    maxOldGenerationSizeMb: 512 # worker heap cap
 ```
 
-每个字段都会验证并提供默认值；`maxOutputBytes` 必须是至少 4 字节的安全整数，其余字段必须是有限正数，`maxWallMs` 还必须不超过 `2147483647`（Node 的 `setTimeout` 最大延迟），此外没有其他可调项。
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `computeMs` | `60,000` | 忙碌时间预算：worker 实测事件循环活跃时间超过该值时，运行以 `timeout` 失败 |
+| `maxWallMs` | `600,000` | 墙钟上限，为忙碌时间无法观测的等待兜底；最大 `2_147_483_647` |
+| `maxOutputBytes` | `67,108,864` | 序列化日志加完成值或失败消息的硬上限；至少 `4` |
+| `maxOldGenerationSizeMb` | `512` | worker 堆上限；溢出会杀死 worker，并以 `worker-exit` 呈现 |
 
-## 设计
+每个字段在加载时都会验证并提供默认值；没有其他可调项。生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-code-runtime-worker-thread)是每个受支持字段的穷尽式真源。
 
-- **每次运行使用一个全新 worker，不设池化**：程序所在的世界会随 worker 一同终止，不会留下需要记录的跨运行状态，也无法发生状态泄漏；仅凭会话日志即可重建运行。
-- **在执行上下文中，由宿主侧剥离类型**：程序会包裹在异步函数外壳中，通过 `node:module` 的 `stripTypeScriptTypes` 剥离类型（只支持可擦除语法；`enum`／namespace 会作为程序 `exception` 被拒绝，且不会启动 worker），再按字节位置切回原内容。之后程序作为 `AsyncFunction` 的函数体执行，因此顶层 `await`／`return` 可用。
-- **端口把对端视为不可信**：模型代码能够访问 `parentPort` 并伪造通信，因此任何代码读取入站消息前，系统都会验证其形状并重新构建（`null`、原始值、无效类型和格式错误的载荷会被静默丢弃；伪造的额外字段绝不会被带入）；宿主对每个调用 id 最多响应一次，只将绑定名称解析为自有属性（伪造的 `constructor` 无法沿原型链访问），丢弃结算后的回复，并验证每个绑定 resolve 值与完成值是否为无损 JSON。伪造的 `log`／`done` 消息无法绕过外层上限：宿主会再次验证，并统计每条获准日志以及完成值或诊断。worker 侧命名空间使用 null-prototype 和 `defineProperty`，因此形似 `__proto__` 的绑定名称只是普通键。
-- **绑定调用被拒绝时使用的异常类属于请求数据**：可选命名空间描述符会指定构造器全局变量，以及用于接收调用失败的成员名称的自有属性。worker 会创建并注入该真实类，使 `instanceof` 生效，同时无需硬编码 `tools` 或 `ToolCallError`；全局变量无效或冲突的声明会在启动 worker 前失败。失败路径使用模块捕获的错误 intrinsic 与属性定义 intrinsic，以及 null-prototype 描述符，因此模型之后的修改无法把被拒绝的绑定变成 worker 崩溃。
-- **两个独立预算，因为对端不可信**：`computeMs` 统计 worker 实际测得的忙碌时间（轮询 `worker.performance.eventLoopUtilization()`）；热循环无法借助待完成的诱饵 dispatch 隐藏，程序等待慢工具时则不累计。`maxWallMs` 为忙碌时间无法观测的情况兜底（例如等待永远不会 resolve 的 promise）。二者最终都会调用 `worker.terminate()`，连同步热循环也能终止；堆溢出会表现为 worker 的 OOM 退出（`kind: 'worker-exit'`）。`maxWallMs` 在加载时会对照 `MAX_TIMER_DELAY_MS` 做范围校验：`setTimeout` 会把更长的延迟限制为 1 ms，仅有正数校验会放行一个在第一个 tick 就到期的上限。`computeMs` 不需要这道上界，因为它对照的是实测占用率，而不是喂给定时器。
-- **中间绑定值是完整 JSON**：绑定参数与 resolve 值会接受无损 JSON 校验，并在没有字节上限的情况下传输。worker 会在执行不可信代码前捕获校验原语，因此对全局对象或原型的修改无法削弱校验或字节计量。中间值绝不会进入外层输出账本或模型上下文；上限仍来自提供方／执行器获取限制与进程／worker 内存。
-- **日志主动流入一个外层账本**：console／stdout／stderr 文本按产生顺序经端口传输，因此超时或被终止的程序仍会显示已经打印的内容。worker 会精确统计 JSON 字符串的字节数，并在发送完成值和异常诊断前，根据组合预算的剩余量预检；因此，抛出的百万字节 stack 会在 worker 边界变成固定的 `output-limit` 诊断。绕过补丁 stream 槽的原生写入会到达独立于完成端口的 pipe，因此宿主会针对这些字节和不可信伪造通信再次执行账本统计；在物化结果前，结算过程会持续进行有界 pipe 捕获，直到 worker 完成终止。`maxOutputBytes` 统计外层 `logs` 数组加完成值或失败消息载荷的 JSON 序列化；固定的 `CodeRunResult` 字段名、花括号、有界错误 kind 标签，以及后续呈现空白不计入这份可变载荷账本。未超过上限时会返回精确值；有损完成值属于 `invalid-output`，组合溢出属于 `output-limit`，不会用 inspected string 代替。失败会保留能容纳的已捕获前缀，之后按普通外层 `run_code` 落盘策略处理。
-- **空环境**：worker 使用 `env: {}` 和 `execArgv: []`，既不会获得环境变量中的凭据（比 spawn 命令的清理环境规则更严格），也不会继承 loader 标志。
-- **dispose（资源释放）时等待完全停稳**：清理会使进行中的运行以 `abort` 失败，并会等待每个 worker 退出后再完成。
+### 运行返回什么
 
-## 未构建与已构建的 worker 入口
+成功的运行把程序的无损 JSON 完成值作为 `result.value` 返回，把程序打印的文本按顺序作为 `result.logs` 返回。顶层 `await`／`return` 可用，程序可以把宿主提供的绑定函数（Code Mode 暴露一个 `tools` 对象）当作普通异步调用。
 
-源代码模式通过 Node 原生类型剥离加载只包含可擦除语法的 `src/worker.ts`。其传递运行时闭包只包含 Node 内置模块和相对源模块，因此全新 checkout 绝不需要兄弟工作区包尚未构建的 `lib/` 导出。worker 本地和会话自有的 JSON 边界都会在消息端口两侧展平并重建已验证值，使应用嵌套永远不会进入 structured clone。构建模式会把兄弟文件 `lib/worker.cjs` 作为文件系统路径传入，因为 pkg 的虚拟文件系统（VFS）Worker hook 要求 CommonJS；同一路径也可在普通 Node 下使用。对这个已发布入口路径进行测试的仓库级要求由[测试策略](../../../docs/testing.zh.md)规定。
+### 包含而非安全边界
 
-SDK 对外提供默认及具名导出的 `WorkerThreadCodeRuntime` 类，以及 `Config`。运行所用的 `./worker` 子路径仅作为打包后的 spawn 入口存在；wire 协议与启动辅助模块是源代码私有的实现细节。
+程序运行时的权限与 bash 工具相当：它可以访问 Node API，后端也刻意不承诺与宿主的隔离。它提供的是包含——独立 isolate、空环境（没有环境变量凭据，也不继承 loader 标志）、可配置堆上限，以及也能终止同步热循环的强制终止。程序派生的 OS 进程在 `terminate()` 后仍然存活，需要部署层面的清理。
 
+### 可能出什么问题
+
+每个程序结果都以结果 resolve，因此失败的运行是 `result.error`，而不是 rejection：语法错误或不可擦除的 TypeScript（`enum`、namespace）在任何 worker 启动前就以 `exception` 失败；预算到期是 `timeout`；中止信号是 `abort`；堆溢出或其他 worker 终止是 `worker-exit`；不是无损 JSON 的完成值是 `invalid-output`；超出上限的序列化输出是 `output-limit`——并保留能容纳的已捕获日志前缀。reject 只表示调用方误用，例如在 dispose（资源释放）后提交运行。

+## 理解实现
+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释后端背后的设计；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+后端建立在一个分离之上：**包含，而非安全边界**。模型代码拥有与 bash 等价的信任（[Code Mode Agent Note](../../../.agents/notes/implemented/feature/2026-06-15-code-mode.zh.md) 的 Trust posture），因此设计追求可重建性与有界资源使用，而非硬性的多租户边界——那需要等待容器级后端。每次运行使用一个全新的 worker，程序的世界随 worker 一同终止：不存在可泄漏、也无需记录的跨运行状态，仅凭会话日志即可重建一次运行。
+
+### 执行流程
+
+一次运行在宿主侧剥离类型（`node:module` 的 `stripTypeScriptTypes`，保持字节位置不变），包裹为异步函数的函数体使顶层 `await`／`return` 可用，然后发送给全新的 worker，由 bootstrap 物化绑定命名空间。绑定调用以无损 JSON 跨消息端口传递，每个调用 id 至多应答一次。日志文本主动流向宿主，因此被终止的程序仍会显示已打印的内容。恰好一个结果结算运行——`done` 帧、预算到期、中止或 worker 终止——之后宿主终止 worker 并等待其退出。
+
+### 把对端视为不可信
+
+模型代码能够访问 `parentPort` 并伪造通信，因此任何代码读取入站消息前，系统都会逐字段验证并重建：伪造的额外字段绝不随行，非数字的 call id 绝不会被回显进 reply，绑定名称只解析为自有属性（伪造的 `constructor` 无法沿原型链访问），垃圾被静默丢弃。worker 侧命名空间使用 null-prototype，因此形似 `__proto__` 的绑定名称只是普通键。
+
+### 预算
+
+存在两个独立预算，因为对端不可信：`computeMs` 计量 worker 的实测忙碌时间（每 25 ms 轮询一次 `eventLoopUtilization()`），因此热循环无论是否有诱饵 dispatch 在途都会到期，而等待慢绑定的程序不累计；`maxWallMs` 为忙碌时间无法观测的情况兜底，例如永远不会 resolve 的 promise。二者最终都会调用 `worker.terminate()`。`maxWallMs` 在加载时对照 `MAX_TIMER_DELAY_MS` 做范围校验，因为 `setTimeout` 会把更长的延迟限制为 1 ms。
+
+### 输出账本
+
+`maxOutputBytes` 统计外层 `logs` 数组加完成值或失败消息载荷的 JSON 序列化；固定的 `CodeRunResult` 字段名与信封语法不计入这份账本。未超过上限时返回精确值；有损完成值属于 `invalid-output`，组合溢出属于 `output-limit`，不会用 inspected string 代替。失败会保留日志中能容纳的已捕获前缀。

-The **`CodeRuntime`** (`ctx.codeRuntime`) defines WHAT a code runtime does — run one model-written program against a set of host-provided async bindings and report `{ value, logs, error? }` — without saying HOW.
+## Summary
 
-This package owns the Service Definition role of the capability (the bash trio is the template — see [capability seams](../../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.md)): providers subclass `CodeRuntime` and register the service; the Consumer is the tool registry's Code Mode, which generates the model-facing SDK and bridges tool dispatch — both specified in the [Code Mode Agent Note](../../../.agents/notes/implemented/feature/2026-06-15-code-mode.md), whose first provider is a Node worker-thread backend. The runtime knows nothing about tools or sessions: it is handed named async functions and a program string, and everything tool-shaped stays with the Consumer.
+`dsh-code-runtime` defines what a code runtime does: run one model-written program against a set of host-provided async functions and report `{ value, logs, error? }` — without dictating how any backend implements it. Load it in a composition with a backend and the service is available as `ctx.codeRuntime`; Code Mode in `dsh-tools` then runs model-written programs that compose tools. Every request runs once with no state carried between runs, and every program outcome — including failures — resolves as a result field rather than a rejection. The runtime knows nothing about tools or sessions: it is handed a program and named bindings, and everything tool-shaped stays with the consumer.

+## Use this package
+
+Choose this package when you compose a deployment that executes model-written programs, consume `ctx.codeRuntime` directly, or build a backend that runs programs. In the shipped composition, Code Mode in `dsh-tools` is the consumer: only what the program printed and returned re-enters the conversation.
+
+### Run a program
+
+Give the runtime a program source and one or more binding namespaces. Each namespace becomes one global object of async functions inside the program — Code Mode passes one under `tools`. The program runs as the body of an async function, so top-level `await` and `return` work; a lossless-JSON completion becomes `result.value`, emitted text arrives in order as `result.logs`, and any failure is reported in `result.error` with a kind you can branch on. The runtime never rejects for a program failure — rejection means you misused the seam, for example by submitting a run after disposal.
+
+```text
+const result = await ctx.codeRuntime.run({
+  program: 'return await tools.add({ a: 1, b: 2 })',
+  bindings: [{ global: 'tools', functions: { add: async (args) => args.a + args.b } }],
+})
+// result.value === 3
+```
+
+### Choose a backend
+
+Backends declare two descriptors you can rely on: `language` — what the program must be written in, with `'typescript'` and `'python'` as the well-known values and only TypeScript shipped — and `isolation` — the execution substrate (`'worker-thread'`, `'process'`, `'container'`), a label for deployments and diagnostics, not a security claim. The shipped backend is [`dsh-code-runtime-worker-thread`](../code-runtime-worker-thread/README.md), which executes TypeScript in a fresh Node worker thread; [`dsh-code-runtime-python`](../code-runtime-python/README.md) owns the wire protocol for the CPython backend.
+
+### Name your bindings portably
+
+Binding-global and error-class names are language-portable: they must match `[A-Za-z_][A-Za-z0-9_]*`, avoid every portable target language's reserved words, and avoid backend-owned slots, so one namespace list is valid against every backend. A name like `$tools`, `lambda`, or `console` fails the run before it starts; the exact exclusion sets are part of the seam contract.
+
+### What can go wrong
+
+Failures arrive as `result.error` with an orthogonal `kind`: the program threw or failed to parse (`exception`), a budget expired (`timeout`), the run was aborted (`abort`), the execution substrate died (`worker-exit`), the completion value was not lossless JSON (`invalid-output`), or the serialized output exceeded the cap (`output-limit`). Each kind carries a model-feedable message. `run()` rejects only for seam misuse, such as a run submitted after disposal or a binding name that fails the portable-identifier rules.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design behind the seam; observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The package is the Service Definition role of the code-execution capability seam ([capability seams](../../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.md)): an abstract `CodeRuntime extends Service` registered as `ctx.codeRuntime`, plus the vocabulary both backends and the consumer share. Providers subclass `CodeRuntime`, implement `run`, and register the service; the consumer (Code Mode in `dsh-tools`) generates the model-facing SDK and bridges tool dispatch. The runtime stays ignorant of tools and sessions by contract: it receives a program and named async bindings and returns `{ value, logs, error? }`.
+
+### Service API
+
+The contract is three members a backend implements: `run(request)` executes one program against the request's bindings and resolves every program outcome — parse/transform failure, thrown exception, invalid completion, output overflow, budget expiry, abort, or substrate death — as a result `error` field, with rejection reserved for caller misuse such as a run submitted after disposal; `language` and `isolation` are read-only descriptors labeling the source language and execution substrate for deployments and diagnostics.
+
+The exhaustive semantics live in the [code runtime subsystem reference](../../../docs/subsystems/code-runtime.md); the exact signatures are in [`src/index.ts`](src/index.ts).
+
+### Vocabulary
+
+`CodeRunRequest` (`program`, `bindings`, `signal?`) carries everything the runtime acts on; defaulting (time budgets, output caps) is each provider's validated config, never a hidden `??` inside `run()`. `bindings` is a list of `CodeBindingNamespace`s (`global` + `functions` + optional `errorClass`), each exposed to the program as one global object of async callables returning `CodeJsonValue` — the seam's structural lossless-JSON type. An `errorClass` descriptor names a real program-global constructor and the own property that receives the rejected member name, so backends never learn consumer terms such as `ToolCallError`. `CodeRunResult` reports the lossless-JSON completion `value?`, ordered `logs: string[]`, and `error?` (`CodeRunFailure`: orthogonal `kind` + model-feedable `message`). See `src/types.ts` for the full contracts.
+
+### Portable identifiers
+
+Binding-global and error-class names are language-portable: they must match the identifier subset `[A-Za-z_][A-Za-z0-9_]*` (no JS-only `$`) and clear the seam-exported exclusion sets, so one `bindings` list is valid against every backend. The package exports the contract every backend enforces — `PORTABLE_RESERVED_WORDS` (ECMAScript ∪ Python reserved words), `RESERVED_BINDING_GLOBALS` (backend-owned globals such as `console` and `__dsh_main__`), `RESERVED_ERROR_MEMBERS` and `DUNDER_MEMBER` (error-member exclusions) — so a name like `$tools`, `lambda`, or `__dsh_main__` makes `run()` reject as seam misuse on any backend. See `src/index.ts` for the exact sets.
+
+### Source map
+
+| File | Role |
 |---|---|
-| `run(request)` | Execute one program against the request's bindings. **Resolves with an error FIELD for every program outcome** — parse/transform failure, thrown exception, invalid completion, output overflow, budget expiry, abort, or substrate death (`CodeRunFailure`'s orthogonal `kind` taxonomy); it rejects only for caller misuse of the Service Definition contract (e.g. a run submitted after disposal). The program runs as the body of an async function: top-level `await`/`return` work, and a lossless JSON completion becomes `result.value`. |
-| `language` | Readonly descriptor: the source language `run` expects. `'typescript'` and `'python'` are the well-known values — those `dsh-tools` presents; only `'typescript'` has a published backend. Informational, not gating — a consumer that generates language-specific presentation switches on it and fails loud on a language it cannot present. |
-| `isolation` | Readonly descriptor: the execution substrate (`'worker-thread'`, `'process'`, `'container'`). A label for deployments and diagnostics, **not a security claim**. |
+| [`src/index.ts`](src/index.ts) | Plugin entry: abstract `CodeRuntime` service and the portable-identifier exclusion sets |
+| [`src/types.ts`](src/types.ts) | Vocabulary: `CodeRunRequest`, `CodeBindingNamespace`, `CodeJsonValue`, `CodeRunResult`, `CodeRunFailure` |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; the seam registers no mutable data relation) |
 
-Semantics every implementation must honor (contract details in the class JSDoc): binding calls bridge complete lossless-JSON arguments and resolutions with no seam-level byte cap; the program is treated as a hostile peer (arbitrary binding names are own properties, malformed traffic never crashes the host); no state survives between runs; disposal terminates in-flight runs AND awaits their exit before completing.
+</details>
 
-## Vocabulary
+-----
 
-`CodeRunRequest` (`program`, `bindings`, `signal?`) carries everything the runtime acts on — defaulting (time budgets and outer-output cap) is the provider's validated config, never a hidden `??` inside `run()`. `bindings` is a list of `CodeBindingNamespace`s (`global` + `functions` + optional `errorClass`), each exposed to the program as one global object of async callables returning `CodeJsonValue`, the service-local structural equivalent of canonical `JsonValue` that keeps this Service Definition package independent of sessions. An `errorClass` descriptor names a real program-global constructor and the own property that receives the rejected member name; runtimes remain independent of Consumer terms such as `ToolCallError`. `CodeRunResult` reports the lossless JSON completion `value?`, ordered `logs: string[]`, and the `error?` (`CodeRunFailure`: `kind` + model-feedable `message`). See `src/types.ts` for the full contracts.

+## Further Exploration
 
-Binding-global and error-class names are **language-portable**: they must match the identifier subset `[A-Za-z_][A-Za-z0-9_]*` (no JS-only `$`) and clear the seam-exported exclusion sets, so one `bindings` list is valid against every backend regardless of its `language`. The package exports the contract every backend enforces — `PORTABLE_RESERVED_WORDS` (ECMAScript ∪ Python reserved words), `RESERVED_BINDING_GLOBALS` (backend-owned globals such as `console`), `RESERVED_ERROR_MEMBERS` and `DUNDER_MEMBER` (error-member exclusions) — so a name like `$tools`, `lambda`, or `__dsh_main__` makes `run()` reject as seam misuse on any backend, not just some. See `src/index.ts` for the exact sets and rationale.

+
+#### Future: persistent kernel backend
+
+A REPL-style kernel that keeps state across `run_code` calls remains undecided; it would need its own logging story, because the no-state-between-runs contract is what keeps every request reconstructable from the session log alone.

+#### Future: container backend

+A container-class backend would provide a hard multi-tenant boundary for both code and shell execution; nothing is decided beyond the well-known `isolation` value.

+## 使用本包
+
+当你要组合一个执行模型程序的部署、直接消费 `ctx.codeRuntime`，或构建运行程序的后端时，选择本包。在已发布的组合中，`dsh-tools` 里的 Code Mode 是消费方：只有程序打印和返回的内容重新进入对话。
+
+### 运行一个程序
+
+向运行时提供程序源码与一个或多个绑定命名空间。每个命名空间会成为程序内的一个全局异步函数对象——Code Mode 在 `tools` 下传入一个。程序作为异步函数的函数体运行，因此顶层 `await`／`return` 可用；无损 JSON 完成值成为 `result.value`，输出的文本按顺序进入 `result.logs`，任何失败都以 `result.error` 报告并带有可分支的 kind。运行时绝不会因程序失败而 reject——reject 意味着你误用了 seam，例如在 dispose（资源释放）后提交运行。
+
+```text
+const result = await ctx.codeRuntime.run({
+  program: 'return await tools.add({ a: 1, b: 2 })',
+  bindings: [{ global: 'tools', functions: { add: async (args) => args.a + args.b } }],
+})
+// result.value === 3
+```
+
+### 选择后端
+
+后端声明两个你可以依赖的描述符：`language`——程序必须使用的源语言，已知值为 `'typescript'` 与 `'python'`，目前只有 TypeScript 已发布——以及 `isolation`——执行基底（`'worker-thread'`、`'process'`、`'container'`），仅供部署与诊断使用，不构成安全声明。已发布的后端是 [`dsh-code-runtime-worker-thread`](../code-runtime-worker-thread/README.zh.md)，在全新的 Node Worker 线程中执行 TypeScript；[`dsh-code-runtime-python`](../code-runtime-python/README.zh.md) 持有 CPython 后端的协议格式（wire protocol）。
+
+### 可移植地命名绑定
+
+binding-global 与 error-class 名称是语言可移植的：必须匹配 `[A-Za-z_][A-Za-z0-9_]*`，避开每个可移植目标语言的保留字，并避开后端拥有的槽位，因此同一份命名空间列表对每个后端都有效。`$tools`、`lambda` 或 `console` 之类的名称会在运行开始前失败；确切的排除集是 seam 约定的一部分。
+
+### 可能出什么问题
+
+失败以 `result.error` 返回，并带正交的 `kind`：程序抛出或解析失败（`exception`）、预算到期（`timeout`）、运行被中止（`abort`）、执行基底终止（`worker-exit`）、完成值不是无损 JSON（`invalid-output`），或序列化输出超过上限（`output-limit`）。每种 kind 都带一条可反馈给模型的消息。`run()` 只在 seam 误用时 reject，例如在 dispose 后提交运行，或绑定名称不符合可移植标识符规则。

+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释 seam 背后的设计；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+本包是代码执行能力 seam 的 Service Definition 角色（[能力 seam](../../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.zh.md)）：一个注册为 `ctx.codeRuntime` 的抽象 `CodeRuntime extends Service`，加上两个后端与消费方共享的词汇。提供方继承 `CodeRuntime`、实现 `run` 并注册服务；消费方（`dsh-tools` 中的 Code Mode）生成面向模型的 SDK 并桥接工具分发。按约定，运行时不了解工具与会话：它接收程序与具名异步绑定，返回 `{ value, logs, error? }`。
+
+### 服务 API
+
+约定是后端实现的三个成员：`run(request)` 针对请求的绑定执行一段程序，并把每个程序结果——解析／转换失败、抛出异常、无效完成值、输出溢出、预算到期、中止或基底终止——都作为结果 `error` 字段 resolve，reject 只留给调用方误用，例如在 dispose 后提交运行；`language` 与 `isolation` 是只读描述符，为部署与诊断标注源语言与执行基底。
+
+穷尽式语义见[代码运行时子系统参考](../../../docs/subsystems/code-runtime.zh.md)；确切签名见 [`src/index.ts`](src/index.ts)。
+
+### 词汇
+
+`CodeRunRequest`（`program`、`bindings`、`signal?`）携带运行时操作所需的全部内容；默认值（时间预算、输出上限）来自各提供方的已验证配置，绝不是 `run()` 内部隐藏的 `??`。`bindings` 是 `CodeBindingNamespace` 列表（`global` + `functions` + 可选 `errorClass`），每个命名空间作为程序内的一个全局异步可调用函数对象公开，返回 `CodeJsonValue`——seam 的结构性无损 JSON 类型。`errorClass` 描述符点名真实的程序全局构造器，以及用于接收被拒绝成员名称的自有属性，因此后端永远不会得知 `ToolCallError` 之类的 Consumer 术语。`CodeRunResult` 报告无损 JSON 完成值 `value?`、有序的 `logs: string[]` 和 `error?`（`CodeRunFailure`：正交 `kind` + 可反馈给模型的 `message`）。完整约定见 `src/types.ts`。
+
+### 可移植标识符
+
+binding-global 与 error-class 名称是语言可移植的：必须匹配标识符子集 `[A-Za-z_][A-Za-z0-9_]*`（不含 JS 专有的 `$`）并通过 seam 导出的排除集，因此同一份 `bindings` 列表对每个后端都有效。本包导出每个后端都执行的约定——`PORTABLE_RESERVED_WORDS`（ECMAScript ∪ Python 保留字）、`RESERVED_BINDING_GLOBALS`（如 `console`、`__dsh_main__` 等后端拥有的 global）、`RESERVED_ERROR_MEMBERS` 与 `DUNDER_MEMBER`（error-member 排除）——因此 `$tools`、`lambda` 或 `__dsh_main__` 之类的名称会让 `run()` 在任何后端上作为 seam 误用而 reject。确切集合见 `src/index.ts`。
+
+### 源码地图
+
+| 文件 | 职责 |
 |---|---|
-| `run(request)` | 针对请求的绑定执行一段程序。**所有程序失败结果都通过 resolve 结果中的 error 字段报告**：包括解析／转换失败、抛出异常、无效完成值、输出溢出、预算到期、中止或执行基底终止（由 `CodeRunFailure` 的正交 `kind` 分类表示）；只有调用方误用 Service Definition 约定时才 reject（例如 dispose（资源释放）后仍提交运行）。程序作为异步函数的函数体运行，因此顶层 `await`／`return` 可用，无损 JSON 完成值会成为 `result.value`。 |
-| `language` | 只读描述符：`run` 期望的源语言。已知值为 `'typescript'` 与 `'python'`——`dsh-tools` 能呈现的那些；其中只有 `'typescript'` 有已发布的后端。仅供参考，不作门禁；生成语言专用呈现的消费方会根据该值选择分支，遇到无法呈现的语言时明确失败。 |
-| `isolation` | 只读描述符：执行基底（`'worker-thread'`、`'process'`、`'container'`）。供部署与诊断使用，**不构成安全声明**。 |
+| [`src/index.ts`](src/index.ts) | 插件入口：抽象 `CodeRuntime` 服务与可移植标识符排除集 |
+| [`src/types.ts`](src/types.ts) | 词汇：`CodeRunRequest`、`CodeBindingNamespace`、`CodeJsonValue`、`CodeRunResult`、`CodeRunFailure` |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；seam 不注册任何可变数据关系） |
 
-每个实现都必须遵守以下语义（完整约定见类 JSDoc）：绑定调用会桥接完整的无损 JSON 参数与 resolve 值，seam 层不设字节上限；程序被视为敌对对等方（任意绑定名称都会成为自有属性，格式错误的通信绝不能使宿主崩溃）；不同运行之间不保留任何状态；dispose 会终止进行中的运行，并且在完成前等待其退出。
+</details>
 
-## 词汇
+-----
 
-`CodeRunRequest`（`program`、`bindings`、`signal?`）携带运行时操作所需的全部内容；默认值解析（时间预算与外层输出上限）属于提供方的已验证配置，绝不能是隐藏的 `??`，更不能藏在 `run()` 内部。`bindings` 是 `CodeBindingNamespace` 列表（`global` + `functions` + 可选 `errorClass`）；每个命名空间会作为一个由异步可调用函数组成的全局对象公开给程序，这些函数返回 `CodeJsonValue`。后者是服务本地、与规范 `JsonValue` 结构等价的类型，使 Service Definition 包保持独立于会话。`errorClass` 描述符点名真实的程序全局构造器，以及用于接收被拒绝成员名称的自有属性；运行时不依赖 `ToolCallError` 等 Consumer 术语。`CodeRunResult` 报告无损 JSON 完成值 `value?`、有序的 `logs: string[]` 和 `error?`（`CodeRunFailure`：`kind` + 可反馈给模型的 `message`）。完整约定见 `src/types.ts`。
+<a id="further-exploration"></a>
+## 进一步探索
 
-binding-global 与 error-class 名称是**语言可移植**的：必须匹配标识符子集 `[A-Za-z_][A-Za-z0-9_]*`（不含 JS 专有的 `$`）并通过 seam 导出的排除集，因此同一份 `bindings` 列表对每个后端都有效，无论其 `language` 为何。本包导出每个后端都执行的约定——`PORTABLE_RESERVED_WORDS`（ECMAScript ∪ Python 保留字）、`RESERVED_BINDING_GLOBALS`（如 `console` 等后端拥有的 global）、`RESERVED_ERROR_MEMBERS` 与 `DUNDER_MEMBER`（error-member 排除）——因此 `$tools`、`lambda`、`__dsh_main__` 之类的名称会让 `run()` 在任何后端上作为 seam 误用而 reject，而非只在某些后端。确切集合与理由见 `src/index.ts`。

 # compaction/ — compaction capability family
 
 English | [中文](README.zh.md)
 
-A compaction capability family (see [capability seams](../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.md)): a Service Definition, a summarizing provider, a model-free tool-result pruning companion, and a human command Consumer. All **product** packages.
+## Summary
+
+The `compaction/` group keeps long agent conversations working near the model's context limit: older history is condensed into a summary automatically as token pressure builds, on demand with `/compact`, and oversized tool outputs can be trimmed first so there is less to condense. The shipped `dsh` base enables the feature by default — mount the packages explicitly to tune when and how condensation happens. The token measurement that decides when to condense lives in a separate LLM-family service.

 # compaction/ — 压缩能力家族
 
 [English](README.md) | 中文
 
-一个压缩（compaction）能力家族（参见[能力 seam](../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.zh.md)）：Service Definition、摘要提供方、无模型工具结果修剪配套工具，以及用户命令 Consumer。这些全是**产品**包。
+## 概述
+
+`compaction/` 组让长时 agent 会话在接近模型上下文上限时仍能正常工作：token 压力上升时自动把较早历史压缩为摘要，随时可用 `/compact` 按需压缩，超大工具输出也可以先被修剪，从而减少需要压缩的内容。随附 `dsh` 基础配置默认启用该功能——显式挂载各包即可调整压缩发生的时机与方式。决定何时压缩的 token 测量属于独立的 LLM（大语言模型）家族服务。

 # @deepseek-ai/dsh-command-compact
 
 English | [中文](README.zh.md)
 
-Human-facing `/compact` control over [`ctx.compaction`](../compaction/README.md). The plugin registers one global command through [`ctx.commands`](../../interaction/commands/README.md), so every composed command adapter discovers and executes it without a model turn. The [queued manual compaction Agent Note](../../../.agents/notes/implemented/feature/2026-07-30-queued-manual-compaction.md) owns the admission, lock, and durability decisions.
+## Summary
 
-## Command contract
+`dsh-command-compact` adds a `/compact` command to chat UIs: type it and the conversation condenses on demand — the older history is replaced by one summary even before automatic pressure triggers. The command works with any condensation backend and does not consume a model turn; after it finishes you see how many history items were condensed and the estimated tokens saved. While the agent is mid-turn or condensation is already running, it tells you condensation is unavailable. Prompts you send while it runs stay queued and start after it finishes.

+## Use this package
+
+Type `/compact` in a chat UI when the conversation has grown long and you want to condense it immediately. The shipped `dsh` base mounts the command next to the default backend, so it is usually already available.
+
+### Using the command
 
 | Input | Result |
 |---|---|
-| `/compact` | Summarize one useful balanced older span even below automatic pressure, then report the replaced history-item count and estimated tokens after the standalone bracket is flushed. |
-| `/compact` with no compactable history | `No compactable history yet.` — no marker or surface mutation is written. |
-| `/compact <anything>` | `Usage: /compact (no arguments)` — the command takes no arguments and calls no compaction backend. |
+| `/compact` | Condense one useful balanced older span even below automatic pressure, then report the replaced history-item count and estimated tokens. |
+| `/compact` with no compactable history | `No compactable history yet.` — nothing changes. |
+| `/compact <anything>` | `Usage: /compact (no arguments)` — the command takes no arguments. |
 
-The command is backend-independent: it depends only on `compactNow(agent, signal)`. The invoking agent is the exact target, and the dispatching UI's cancellation signal is forwarded through the seam. Every resolved invocation records the executor-owned log-only pair `command/run` / `command/done`; neither event joins model history. On success, `command/done.sourceEventSeq` names the transaction's `compaction/summary` event so a presentation can fold the command lifecycle into its checkpoint without parsing result text or assuming adjacent rows.
+### What you see
 
-Expected `ManualCompactionError` codes become stable direct errors:
+The command turns each expected failure into a stable message you can show directly; the situation on the left is what produced the message on the right.
 
-| Code | Direct result |

 |---|---|
-| `busy` | `Compaction is unavailable because this process has an active compaction, or the agent is not idle.` |
-| `changed` | `The history selected for compaction changed before it could be replaced. The conversation is unchanged; the attempt is recorded in the session log.` |
-| `summary` | `Compaction could not produce a useful summary. The conversation is unchanged; the attempt is recorded in the session log.` |
-| `commit` | `Compaction did not finish cleanly; some session history may have changed. Inspect the current session state before retrying.` |
-| `persistence` | `Compaction finished, but the session could not be saved.` |
+| Compaction already running, or the agent is mid-turn | `Compaction is unavailable because this process has an active compaction, or the agent is not idle.` |

+| Condensation did not finish cleanly | `Compaction did not finish cleanly; some session history may have changed. Inspect the current session state before retrying.` |
+| The conversation could not be saved | `Compaction finished, but the session could not be saved.` |
 
-The busy result is intentionally process-scoped: a live unmatched marker blocks, while a marker older than the newest `session/end-seed` is stale and does not. Unexpected implementation failures reject dispatch. Cancellation remains authoritative; the backend completes its required close/flush cleanup, and the command settles internally as `Compaction cancelled.` while the command executor stops waiting with its cancellation error. Plugin disposal first unregisters `/compact`, then drains every handler that already started, so root teardown cannot pass an aborted command's close or flush boundary.
+Cancelling the command stops the wait: the backend finishes its required cleanup, and the command settles as `Compaction cancelled.` while the UI stops waiting. Failures other than these expected cases surface as errors rather than being silently converted.
 
-Prompts submitted while compaction runs remain accepted in the agent's ordinary FIFO with the same identity and wakeup facts. They start only after the compaction's explicit durability checkpoint and admission release. Idle injected context is not held: it may be logged between `compaction/start` and `compaction/end`, and positional replacement leaves it visible after the checkpoint.

+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the command; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The command is built on three commitments:
+
+- **Backend-independent control.** The handler depends only on `compactNow(agent, signal)`, so it works with any `CompactionEngine` implementation. The invoking agent is the exact target, and the dispatching UI's cancellation signal is forwarded through the seam.
+- **The command lifecycle stays out of model history.** `command/run` and `command/done` are log-only events; `sourceEventSeq` correlates the successful result with the `compaction/summary` event without relying on text or row adjacency.
+- **Quiescent teardown.** The lifecycle effect unregisters `/compact` before draining already-started handlers, so an aborted command's close and flush work settles before root disposal completes.
+
+### Lifecycle and correlation
+
+Every resolved invocation records the executor-owned log-only pair `command/run` / `command/done`; neither event joins model history. On success, `command/done.sourceEventSeq` names the transaction's `compaction/summary` event so a presentation can fold the command lifecycle into its checkpoint without parsing result text or assuming adjacent rows. The busy outcome is intentionally process-scoped: a live unmatched marker blocks, while a marker older than the newest `session/end-seed` is stale and does not. The plugin tracks each real handler promise and unregisters `/compact` before draining handlers that already started, so root teardown cannot pass an aborted command's close or flush boundary. Prompts submitted while compaction runs remain accepted in the agent's ordinary FIFO and start only after the compaction's explicit durability checkpoint and admission release; idle injected context may sit between `compaction/start` and `compaction/end` and stays visible after the checkpoint.

 [English](README.md) | 中文
 
-通过 [`ctx.compaction`](../compaction/README.zh.md) 提供面向用户的 `/compact` 压缩（compaction）控制。该插件通过 [`ctx.commands`](../../interaction/commands/README.zh.md) 注册一个全局命令，因此组合中的每个命令适配器都能发现并执行它，无需模型轮次。[排队手动压缩 Agent Note](../../../.agents/notes/implemented/feature/2026-07-30-queued-manual-compaction.zh.md)拥有接纳、锁与持久性决策。
+## 概述
 
-## 命令约定
+`dsh-command-compact` 为聊天 UI 添加 `/compact` 命令：输入它，对话就会按需压缩——即使尚未触发自动压力，较早历史也会被替换为一条摘要。该命令适用于任何压缩后端，且不消耗模型轮次；完成后你会看到压缩了多少历史项以及估算节省的 token 数。当 agent 正在轮次中或压缩已在运行时，它会告诉你压缩暂不可用。运行期间你发送的提示词会保持排队，并在压缩结束后才开始。

+## 使用本包
+
+当对话已经很长、想立即压缩时，在聊天 UI 中输入 `/compact`。随附 `dsh` 基础配置把该命令挂载在默认后端旁，因此它通常已经可用。
+
+### 使用命令
 
 | 输入 | 结果 |
 |---|---|
-| `/compact` | 即使未达到自动压力，也摘要一段有效、平衡的较早范围；独立标记对 flush 后，报告被替换的历史项数量与估算 token 数。 |
-| `/compact`，但没有可压缩历史 | `No compactable history yet.`：不会写入标记，也不会变更 surface。 |
-| `/compact <anything>` | `Usage: /compact (no arguments)`：该命令不接受参数，也不会调用压缩后端。 |
+| `/compact` | 即使未达到自动压力，也压缩一段有效、平衡的较早范围，然后报告被替换的历史项数量与估算 token 数。 |
+| `/compact`，但没有可压缩历史 | `No compactable history yet.`——不会有任何改变。 |
+| `/compact <anything>` | `Usage: /compact (no arguments)`——该命令不接受参数。 |
 
-该命令与后端无关，只依赖 `compactNow(agent, signal)`。调用该命令的 agent（智能体）就是操作的确切目标，发起分发的 UI 会通过 seam 转发取消信号。每次完成的调用都会记录执行器所属的纯日志事件对 `command/run` / `command/done`；两者都不进入模型历史。成功时，`command/done.sourceEventSeq` 会指明该事务的 `compaction/summary` 事件，让呈现层无须解析结果文本或假定两行相邻，即可将命令生命周期归并到对应检查点中。
+### 你会看到什么
 
-预期的 `ManualCompactionError` 代码会成为稳定的直接错误：

+
+### 设计理念
+
+该命令建立在三项承诺之上：
+
+- **与后端无关的控制。** 处理器只依赖 `compactNow(agent, signal)`，因此可与任何 `CompactionEngine` 实现协作。调用该命令的 agent（智能体）就是操作的确切目标，发起分发的 UI 会通过 seam 转发取消信号。
+- **命令生命周期不进入模型历史。** `command/run` 与 `command/done` 都是仅日志事件；`sourceEventSeq` 将成功结果与 `compaction/summary` 事件关联，不依赖文本或行相邻关系。
+- **安静地销毁。** 生命周期 effect 会先注销 `/compact`，再等待已开始处理器结算，因此已中止命令的闭合与 flush 工作在根级销毁完成前安定下来。
+
+### 生命周期与关联
+
+每次完成的调用都会记录执行器所属的仅日志事件对 `command/run` / `command/done`；两者都不进入模型历史。成功时，`command/done.sourceEventSeq` 会指明该事务的 `compaction/summary` 事件，让呈现层无须解析结果文本或假定两行相邻，即可将命令生命周期归并到对应检查点中。busy 结果有意限定在进程范围内：活动的未匹配标记会阻塞，而早于最新 `session/end-seed` 的标记已陈旧，不会阻塞。插件会跟踪每个真实处理器 promise，并在排空已开始处理器之前注销 `/compact`，因此根级 teardown 不会越过已中止命令的闭合或 flush 边界。压缩运行期间提交的提示词仍会按 agent 的普通 FIFO 获得接纳，并且只在压缩的显式持久性检查点和接纳预留释放后启动；空闲注入的上下文可以位于 `compaction/start` 与 `compaction/end` 之间，并在检查点之后保持可见。

 English | [中文](README.zh.md)
 
-The **basic compaction backend**: a `BasicCompactionEngine` implementing the `@deepseek-ai/dsh-compaction` Service Definition with reusable `ctx.tokenMeter` pressure, token-budget retention, and summarization as a direct one-shot `ctx.llm.stream()` call that replays the conversation prefix to reuse the provider's KV cache (interceptable at `llm/stream`).
+## Summary
 
-This package owns the Service Provider role of the compaction capability — see the [Service Definition package](../compaction/README.md) for its contract and the [capability-seam Agent Note](../../../.agents/notes/implemented/feature/2026-06-18-compaction-capability-seam.md) for the design.
+`dsh-compaction-basic` keeps long agent conversations working near the model's context limit. As token pressure builds, it automatically condenses the oldest part of the conversation into a summary and keeps the recent part intact; after a context-overflow error it condenses and retries. You can also condense on demand with `/compact` from `dsh-command-compact`, and mount `dsh-compaction-tool-result-pruner` to trim oversized tool outputs first. Condensation costs one extra model request that reads the selected history and writes the summary; only the summary text is kept. It condenses derived history only — it cannot shrink the system prompt, tools, or session prefix, and one indivisible unit such as a single huge tool call cannot be split.

-- **Measurement** — the singleton `ctx.tokenMeter` prices the latest canonical logged envelope and current surface at one consumed-log revision, under the routed model's declared request-image pricing when its adapter declares one. Step-boundary pressure therefore includes the actual system prompt, tools, routing, assistant completion, tool results, buffered context, steering, and route-priced image history; trigger, recent-tail retention, range selection, and the summary-shrink comparison all read the same route-priced per-node figures, while the logged shadow price of a replaced range stays on the route-independent fixed heuristic so pure projection folds remain consistent.
-- **Routed policy** — proactive pressure resolves capacity from the adapter that owns the latest durable provider/model route, then scales the default policy plus an optional exact-target override into concrete token budgets. Model discovery remains advisory and is not consulted.
-- **Model-free pruning** — after pressure or canonical overflow qualifies, the optional [`ctx.toolResultPruner`](../compaction-tool-result-pruner/README.md) service rewrites oversized tool results before range selection. Compact-basic remeasures through `ctx.tokenMeter`, skips summarization when pressure becomes safe, and otherwise summarizes the pruned surface. Below-pressure step checks never prune.
-- **Retention** — compact the oldest whole surface units while preserving a recent tail and balanced tool-call/result cuts through the [`dsh-compaction` boundary helpers](../compaction/README.md#tool-pairing-boundaries). Turn boundaries do not protect old steps inside a runaway turn. An open indivisible tail declines until it closes. The optional pruner can repair an oversized closed tool unit when its text-bearing result is the removable bulk; indivisible non-tool units and non-prunable tool remainders remain out of scope.
-- **Convergence** — retry head-checkpoint compaction up to `compactionRetries`; reject a summary that does not shrink its source, and throw if retries cannot return below threshold.
-- **Summarization** — a direct `llm/stream` call uses the configured provider/model pair and cap, falling back to the latest logged request target and then the agent target, without running the loop-only `agent/request` extension point. The call replays the conversation's own system prompt, tools, and shadowed-region messages verbatim, including image references, and appends the compaction instruction as the final user message, so it reuses the provider's warm prefix cache instead of invalidating it. The selected adapter must resolve or explicitly reject those images. It sets `GenerateOptions.purpose` to `compaction`, which adapters may forward as request attribution (the DeepSeek adapter sends `x-deepseek-harness-compact: 1`) without touching the model-visible body. Only returned text enters the checkpoint, excluding reasoning and tool calls that would leak private reasoning or create an orphaned call; image output fails with `UNSUPPORTED_CONTENT` rather than disappearing.
-- **Framing** — the replacement user message marks established checkpoint context with `<compacted-summary>` tags. The raw summary remains on the `compaction/summary` event, and later automatic cycles merge the prior checkpoint.
-- **Lifecycle** — all entry points share one bracket-first region transaction. It validates the range and live lock, appends `compaction/start` synchronously, prepares and awaits the summary, revalidates, appends `compaction/summary` plus the replacement, and makes exactly one closing attempt. Automatic and explicit-region calls require a numeric open-turn owner and whole-surface stability; the serial `agent/pre-step` listener checks pressure before request derivation, while canonical provider overflow enters through `agent/request-error` and authorizes retry only after durable surface progress. `compactNow()` reserves idle admission, uses `turn: null`, accepts append-only context outside its selected span, flushes every closed attempt, and releases admission in `finally`.
-- **Overflow recovery** — provider-confirmed overflow needs no capacity metadata: it bypasses normal pressure and retention, prunes, then attempts one maximal balanced head reduction while leaving the newest indivisible unit. Retry is authorized whenever `surface.replaceGeneration` advances, including when pruning lands before later summary work throws. No replacement, an exhausted target-specific cap, cancellation, or an unknown/noncanonical error preserves the original provider failure.
-- **Failure handling** — a live unmatched `compaction/start` is the durable lock. An unmatched marker before a newer `session/end-seed` is stale evidence from a prior lifecycle and does not block; one after that boundary reports `busy`. Summary and changed-span failures close with an error and leave the conversation surface untouched, though the attempt remains in the log. A failed close deliberately leaves a blocking orphan. Operational pressure failures warn and continue, while overflow-recovery failure preserves the original provider error only when no earlier replacement advanced the surface. Cancellation remains authoritative after cleanup and durability.
+-----
 
-The protected `summarize()` method is the sole subclass hook. A template- or remote-summarizer subclass can override it while pressure, retention, cited source events, shrink validation, and shadowed-token accounting stay on `ctx.tokenMeter`. The hook returns the safe summary plus the complete provider output, call envelope, and usage when available (`{ summary, rawOutput?, llmStreamCall?, provider, model, maxTokens?, usage? }`); `llmStreamCall: true` means producing that result consumed exactly one call through this context's `ctx.llm.stream()` and requires complete `rawOutput`, while unmarked `rawOutput` does not identify the call path. The transaction preserves those fields on `compaction/summary`.
+<a id="use-this-package"></a>
+## Use this package
 
-## Config (`BasicCompactionConfig`)
+Mount this package to get automatic conversation condensation in a composition that already provides an LLM, session storage, and token measurement. The shipped `dsh` base enables it by default; mount it explicitly to control when condensation starts.
 
-Every setting is optional. Top-level policy fields are defaults for every routed model; `modelPolicies` applies partial overrides to exact provider/model pairs. At pressure time, compaction-basic asks the owning LLM adapter for that route's context capacity and resolves absolute budgets. Unrecognized keys, duplicate targets, mutually exclusive retention forms, and a merged `retainRatio` that is not below `thresholdRatio` fail plugin load. An absolute `retainTokens` budget that is not below its scaled threshold fails on the first resolvable target because that comparison requires model capacity.
+### What you get
 
-| Key | Required | Meaning |
-|---|---|---|
-| `thresholdRatio` | no (default `0.8`) | Compact at `floor(routedContextWindow × ratio)`. |
-| `retainRatio` | no (default `0.16`) | Recent surface budget kept verbatim as a fraction of the routed context window; mutually exclusive with `retainTokens`. |
-| `retainTokens` | no | Absolute recent surface budget kept verbatim; mutually exclusive with `retainRatio` and must be below the resolved threshold. |
-| `summarizationProvider` | no (default `''`) | Set together with `summarizationModel`; an empty pair resolves the latest logged request target, then the `AgentOptions` pair. |
-| `summarizationModel` | no (default `''`) | Set together with `summarizationProvider`; an empty pair resolves the latest logged request target, then the `AgentOptions` pair. |
-| `maxTokens` | no (default `8192`) | Provider generation cap for the summarization call; may include reasoning tokens. |
-| `compactionRetries` | no (default `1`) | Extra attempts after the first when pressure remains above threshold. |
-| `maxOverflowRetries` | no (default `1`) | Maximum retries after canonical context-window overflow; `0` disables recovery only. |
-| `modelPolicies` | no (default `[]`) | Exact `{ provider, model, ...partialPolicy }` overrides; matching uses both fields and does not depend on `listModels()`. |
-| `auto` | no (default `true`) | Register step-boundary pressure and overflow-recovery listeners. Set `false` for manual-only. |
+With the default settings you get four behaviors: automatic condensation as the conversation grows toward the model's context limit; recovery after a confirmed context-overflow error, where the conversation condenses and the request retries; on-demand condensation through the `/compact` command; and — when the pruner is mounted — trimming of oversized tool outputs before condensation.
 
-Every `modelPolicies` entry accepts the policy fields above except `auto` and `modelPolicies` itself. If an entry supplies either retention field, it replaces the default policy's retention choice; otherwise retention is inherited. Summarization provider/model remain a pair inside each entry.
+### Smallest working composition
 
-An adapter may return no capacity for a valid dynamic route, and resolved capacity may expose an invalid absolute retention budget. Manual pressure checks then throw a target-specific configuration error; the automatic listener warns once for that exact target and continues with full history. Unrelated operational failures remain independently visible. Canonical provider overflow still attempts recovery because the provider has already established that compaction is necessary.
+Mount session storage, token measurement, the optional pruner, this backend, and optionally the on-demand command:
 
-## Usage
-
-`BasicCompactionEngine` requires `ctx.llm`, `ctx.tokenMeter`, and `ctx.sessions`. The composition below receives `ctx.llm` from its host and installs the other two services:
-
-```ts
-import type { Context } from '@deepseek-ai/cordis'
-import { BasicCompactionEngine } from '@deepseek-ai/dsh-compaction-basic'
-import SessionStore from '@deepseek-ai/dsh-session'
-import TokenMeter from '@deepseek-ai/dsh-token-meter'
-
-export const name = 'compaction-basic'
-export const inject = ['llm']
-
-export function apply(ctx: Context): void {
-  ctx.plugin(SessionStore)
-  ctx.plugin(TokenMeter)
-  ctx.plugin(BasicCompactionEngine)
-}
+```yaml

+- name: '@deepseek-ai/dsh-compaction-tool-result-pruner'
+- name: '@deepseek-ai/dsh-compaction-basic'
+- name: '@deepseek-ai/dsh-command-compact'
 ```
 
-Loading the plugin registers `ctx.compaction`. Add [`dsh-compaction-tool-result-pruner`](../compaction-tool-result-pruner/README.md) as a sibling before this plugin to enable the optional model-free pass. With `auto: true` (the default) it compacts automatically under token pressure. The sibling [`dsh-command-compact`](../command-compact/README.md) calls `ctx.compaction.compactNow(...)`; programmatic callers may also use any seam operation directly.

+### Tuning when condensation starts
+
+All settings are optional. The defaults start condensing at 80% of the routed model's context window and keep the newest 16% verbatim; the table below is the complete policy surface, and the generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-compaction-basic) is the exhaustive source.
+
+| Field | Default | Meaning |
+|---|---|---|
+| `thresholdRatio` | `0.8` | Start condensing at `floor(routedContextWindow × ratio)`. |
+| `retainRatio` | `0.16` | Recent conversation kept verbatim as a fraction of the routed context window; mutually exclusive with `retainTokens`. |
+| `retainTokens` | — | Absolute recent-conversation budget kept verbatim; mutually exclusive with `retainRatio` and must be below the resolved threshold. |

+| `summarizationModel` | `''` | Set together with `summarizationProvider`; an empty pair uses the latest routed request target, then the `AgentOptions` pair. |
+| `maxTokens` | `8192` | Output cap for the summarization request; may include reasoning tokens. |
+| `compactionRetries` | `1` | Extra condensation attempts after the first when pressure remains above threshold. |
+| `maxOverflowRetries` | `1` | Maximum retries after a confirmed context-window overflow; `0` disables recovery only. |
+| `modelPolicies` | `[]` | Exact `{ provider, model, ...partialPolicy }` overrides for individual model routes. |
+| `auto` | `true` | Enable automatic condensation and overflow recovery; set `false` for manual-only operation. |
+
+Misconfiguration fails fast: an unknown setting, a duplicate per-model override, both retention forms together, or a ratio retention that is not below the threshold all reject the plugin at load. An absolute `retainTokens` budget — top-level or per-model — that is not below its threshold fails when that model is first used, because the comparison needs the model's context size.
+
+### What happens when condensation runs
+
+The oldest balanced span is replaced by one summary message and the recent tail stays verbatim; the conversation continues from the summary. The operation reports how many history items were condensed and the estimated tokens freed. If nothing can be condensed safely — for example the whole conversation is one indivisible unit — nothing changes and nothing is written to the session log. If no model is available to write the summary (no configured target and no routed request yet), condensation fails with a clear error telling you to configure the summarization provider and model or route one request.
+
+### On-demand condensation with /compact
+
+With `dsh-command-compact` mounted, type `/compact` in a chat UI to condense immediately, even below the pressure threshold. The command reports how many history items were condensed and the estimated tokens saved. While the agent is mid-turn or condensation is already running, `/compact` reports that condensation is unavailable; prompts you send while it runs are accepted and start after it finishes.
+
+### Trimming oversized tool outputs
+
+Mount `dsh-compaction-tool-result-pruner` before this package to trim oversized tool results as part of condensation. Trimming makes no model call and can remove the need to summarize at all: when the trimmed conversation fits within the threshold, condensation skips the summary. Trimming only runs after a condensation trigger qualifies — a below-pressure conversation is never touched.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the backend; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The backend is built on four commitments:
+
+- **One measurement service prices every decision.** The singleton `ctx.tokenMeter` measures the latest canonical logged envelope and current surface at one consumed-log revision. When the routed adapter declares request-image pricing, the meter applies it to image history. Pressure, recent-tail retention, range selection, and shrink validation use the same route-priced node figures; logged replacement shadow prices stay on the route-independent heuristic so pure projection folds remain consistent.
+- **The log-recorded bracket is the transaction.** All entry points share one bracket-first region transaction: validate the range and live lock, append `compaction/start` synchronously, prepare and await the summary, revalidate, append `compaction/summary` plus the replacement, and make exactly one closing attempt. Automatic and explicit-region calls require a numeric open-turn owner and whole-surface stability; `compactNow()` reserves idle admission, uses `turn: null`, accepts append-only context outside its selected span, flushes every closed attempt, and releases admission in `finally`.
+- **Summarization reuses the provider's warm prefix.** Replaying the last routed request's system prompt, tools, and shadowed-region messages byte-for-byte makes the auxiliary call a genuine prefix of the conversation, so only the trailing instruction and the summary output are uncached.
+- **`summarize()` is the sole subclass hook.** A template- or remote-summarizer subclass can override it while pressure, retention, cited source events, shrink validation, and shadowed-token accounting stay on the token meter.
+
+### Automatic triggers and overflow recovery
+
+With `auto: true`, a serial `agent/pre-step` listener checks pressure before request derivation: it prices the latest durable routed request envelope through `ctx.tokenMeter`, and when pressure crosses the routed model's threshold it prunes, then summarizes the oldest balanced span while keeping a priced recent tail. The `agent/request-error` listener reacts to a provider-confirmed `CONTEXT_WINDOW_EXCEEDED`: it bypasses the normal threshold and retention policy, attempts one maximal balanced head reduction, and authorizes a retry only after the surface replacement generation advances. Cancellation stays authoritative throughout.
+
+Pressure policy resolves capacity from the adapter that owns the durable route. An adapter that returns no capacity for a valid dynamic route makes the manual pressure path throw a target-specific configuration error; the automatic listener warns once for that exact target and continues with full history.
+
+### Summarization mechanics
+
+A direct `ctx.llm.stream()` call uses the configured provider/model pair and cap, falling back to the latest logged request target and then the `AgentOptions` pair, without running the loop-only `agent/request` extension point. The call replays the conversation's own system prompt, tools, and shadowed-region messages verbatim — including image references, which the selected adapter must resolve or explicitly reject — and appends the compaction instruction as the final user message, so it reuses the provider's warm prefix cache instead of invalidating it. The call sets `GenerateOptions.purpose` to `compaction`; only returned text enters the checkpoint, excluding reasoning and tool calls. Image output fails with `UNSUPPORTED_CONTENT` rather than disappearing. The replacement user message frames the summary with `<compacted-summary>` tags; the raw summary remains on the `compaction/summary` event.
+
+### The region transaction
+
+The transaction validates the surface span and the durable lock, appends `compaction/start`, summarizes through the hook, revalidates stability (whole-surface for automatic calls, selected-span for manual calls), rejects a summary that does not shrink its source, appends `compaction/summary` plus the replacement `user/message`, and makes exactly one `compaction/end` attempt. A live unmatched start is the durable lock: an unmatched marker before a newer `session/end-seed` is stale evidence from a prior lifecycle and does not block; one after that boundary reports `busy`. A failed close deliberately leaves a blocking orphan. Cancellation remains authoritative after cleanup and durability.
+
+### Config resolution
+
+`resolveConfig` validates and detaches the defaults, `resolveTargetPolicy` merges an exact provider/model override over them, and `resolveCompactSpec` scales the merged policy into concrete token budgets using the adapter-owned context capacity. Model discovery (`listModels()`) is never consulted for policy; only the durable route's capacity matters.

 - **Some indivisible-unit and envelope-only overflow remains outside surface compaction** — recovery cannot shrink system/tools/prefix, split an indivisible non-tool node, or repair a tool unit whose non-prunable remainder still exceeds the window. The optional pruner can shrink text-bearing tool-result bulk inside an otherwise indivisible pair.
 - **`compactRegion` requires an open turn** — a manual call on a fully-closed session throws ("no open turn") rather than compacting.
 - **Summarization failure preserves the latest durable surface** — before any replacement, the auto path logs a warning and proceeds with full over-budget history. If pruning already landed, a later summarization failure proceeds from that durable pruned surface. Summarization truncation at `maxTokens`, which hidden reasoning tokens can consume, follows the same rule.

 [English](README.md) | 中文
 
-**基础压缩（compaction）后端**：`BasicCompactionEngine` 实现 `@deepseek-ai/dsh-compaction` Service Definition，使用可复用的 `ctx.tokenMeter` 压力、token 预算保留与摘要。摘要是直接的一次性 `ctx.llm.stream()` 调用，它会回放会话前缀以复用提供方的 KV Cache（可在 `llm/stream` 处拦截）。
+## 概述
 
-本包承担压缩能力的 Service Provider 角色；其约定见 [Service Definition 包](../compaction/README.zh.md)，设计见 [能力 seam Agent Note](../../../.agents/notes/implemented/feature/2026-06-18-compaction-capability-seam.zh.md)。
+`dsh-compaction-basic` 让长时 agent 会话在接近模型上下文上限时仍能正常工作。token 压力上升时，它会自动把对话最旧的部分压缩为摘要，并保持近期部分完整；上下文溢出错误发生后，它会压缩并重试。你也可以通过 `dsh-command-compact` 的 `/compact` 按需压缩，并挂载 `dsh-compaction-tool-result-pruner` 先修剪超大工具输出。压缩的代价是一次额外的模型请求，它读取所选历史并写出摘要；只有摘要文本会被保留。它只压缩派生历史——无法缩减系统提示词、工具或会话前缀，也无法拆分单个不可分单元（例如一次超大工具调用）。

-- **测量**：单例 `ctx.tokenMeter` 会在同一个已消费日志 revision 上，计量最新一份规范化已记录 envelope 与当前表层的 token 用量；当路由模型的适配器声明了请求图片定价时，按该定价计量。因此，步骤边界的压力计量会包含实际系统提示词、工具、路由、assistant 完成、工具结果、缓冲上下文、steering（中途引导）与按路由定价的图片历史；触发、近期尾部保留、范围选择与摘要收缩比较读取同一套路由定价的逐节点数字，而被替换范围记录的影子价保持在与路由无关的固定启发式规则上，使纯投影 fold 保持一致。
-- **路由策略**：主动压力从拥有最新持久提供方／模型路由的适配器解析容量，再将默认策略与可选的精确目标覆盖缩放为具体 token 预算。模型发现仍仅供参考，不参与此处的策略解析。
-- **不依赖模型的剪枝**：在压力或规范溢出符合条件后，可选的 [`ctx.toolResultPruner`](../compaction-tool-result-pruner/README.zh.md) 服务会在选择范围之前改写超大工具结果。Compact-basic 通过 `ctx.tokenMeter` 重新测量；如果压力已回到安全范围，就跳过摘要，否则对已剪枝的表层进行摘要。低于压力的步骤检查绝不剪枝。
-- **保留**：压缩最旧的完整表层单元，同时保留近期尾部，并通过 [`dsh-compaction` 边界 helper](../compaction/README.zh.md#tool-pairing-boundaries) 将切分点调整到工具调用／结果配对平衡的位置。轮次边界不会保护失控轮次内的旧步骤。尚未闭合且不可分的尾部会在闭合前拒绝压缩。当闭合的超大工具单元以文本型结果为可移除主体时，可选 pruner 可以修复它；不可分的非工具单元与不可剪枝的工具剩余部分不在范围内。
-- **收敛**：最多按 `compactionRetries` 重试头部检查点压缩；拒绝不能缩小源内容的摘要，如果重试仍无法回到阈值以下，则抛出异常。
-- **摘要**：直接 `llm/stream` 调用使用已配置的提供方／模型对与上限，回退到最新已记录请求目标，然后再回退到 agent（智能体）目标，而不运行仅用于 agent loop 的 `agent/request` 扩展点。该调用会逐字回放会话自身的系统提示词、工具与已遮蔽区域消息（包括图片引用），并将压缩指令作为最后一条 user 消息追加，从而复用提供方的热前缀 cache，而非使它失效。所选适配器必须解析或明确拒绝这些图片。它将 `GenerateOptions.purpose` 设为 `compaction`，适配器可将其作为请求归因转发（DeepSeek 适配器发送 `x-deepseek-harness-compact: 1`），但不会触碰模型可见的请求体。只有返回的文本会进入检查点；推理（reasoning）和工具调用都会被排除，以免泄露私有推理或产生遗留调用；图片输出会以 `UNSUPPORTED_CONTENT` 失败，而不是消失。
-- **框定**：替换 user 消息使用 `<compacted-summary>` 标签标记已建立的检查点上下文。原始摘要保留在 `compaction/summary` 事件上，后续自动周期会合并之前的检查点。
-- **生命周期**：所有入口点共享一个先记录标记的区域事务。它会验证范围与活动锁，同步追加 `compaction/start`，准备并等待摘要，重新验证，再追加 `compaction/summary` 和替换，最后恰好进行一次闭合尝试。自动调用和显式范围调用要求数字标识的开放轮次归属，并要求整个表层保持稳定；串行 `agent/pre-step` listener 会在派生请求之前检查压力，而规范提供方溢出则经由 `agent/request-error` 进入，并且只在表层取得持久进展后才允许重试。`compactNow()` 会预留空闲接纳，使用 `turn: null`，允许所选 span 之外追加仅追加上下文，flush 每次已闭合尝试，并在 `finally` 中释放接纳预留。
-- **溢出恢复**：提供方已确认的溢出不需容量元数据。它会绕过常规压力与保留，执行剪枝，再尝试一次最大平衡头部缩减，并留下最新不可分单元。只要 `surface.replaceGeneration` 前进，就允许重试，包括剪枝在后续摘要工作抛出异常前已落地的情况。如果没有替换、目标特定上限已耗尽、已取消，或遇到未知／非规范错误，则保留原始提供方失败。
-- **失败处理**：活动的未匹配 `compaction/start` 是持久锁。位于较新 `session/end-seed` 之前的未匹配标记，是先前生命周期留下的陈旧证据，不会阻塞；位于该边界之后的标记报告 `busy`。摘要和 span 变更失败会以错误闭合，并保持会话表层不变，但日志中仍保留该尝试。闭合失败会有意留下阻塞性的未匹配标记。压力检查中的运行故障会发出警告并继续；只有此前没有替换推进表层时，溢出恢复失败才保留原始提供方错误。完成清理与持久化后，取消仍具有最终决定权。
+-----
 
-受保护的 `summarize()` 方法是唯一的子类钩子。基于模板或远程摘要器的子类可以覆盖该方法，同时压力、保留、被引用的源事件、缩减验证与已遮蔽 token 计量仍由 `ctx.tokenMeter` 负责。钩子返回安全摘要，以及完整提供方输出、调用 envelope 和可用时的 usage（`{ summary, rawOutput?, llmStreamCall?, provider, model, maxTokens?, usage? }`）；`llmStreamCall: true` 表示生成该结果时恰好通过此上下文的 `ctx.llm.stream()` 发起了一次调用，且必须提供完整的 `rawOutput`；未带标记的 `rawOutput` 并不能判定调用路径。事务会在 `compaction/summary` 上保留这些字段。
+<a id="use-this-package"></a>
+## 使用本包
 
-## 配置（`BasicCompactionConfig`）
+在已提供 LLM（大语言模型）、会话存储与 token 测量的组合中挂载本包，即可获得自动会话压缩。随附 `dsh` 基础配置默认启用它；需要控制压缩发生的时机时请显式挂载。
 
-所有设置都可选。顶层策略字段是每个已路由模型的默认值；`modelPolicies` 对精确提供方／模型对应用部分覆盖。出现压力时，compaction-basic 会请求所属 LLM（大语言模型）适配器提供该路由的上下文容量，并解析绝对预算。无法识别的配置键、重复目标、互斥保留形式，以及合并后的 `retainRatio` 不低于 `thresholdRatio`，都会使插件加载失败。不低于缩放后阈值的绝对 `retainTokens` 预算会在首次解析出目标时导致失败，因为该比较需要模型容量。
+### 你会得到什么
 
-| Key | 必填 | 含义 |
-|---|---|---|
-| `thresholdRatio` | 否（默认 `0.8`） | 在 `floor(routedContextWindow × ratio)` 处压缩。 |
-| `retainRatio` | 否（默认 `0.16`） | 以已路由上下文窗口的一部分表示逐字保留的近期表层预算；与 `retainTokens` 互斥。 |
-| `retainTokens` | 否 | 逐字保留的近期表层绝对预算；与 `retainRatio` 互斥，并且必须低于已解析阈值。 |
-| `summarizationProvider` | 否（默认 `''`） | 与 `summarizationModel` 一起设置；空对会解析为最新已记录请求目标，再回退到 `AgentOptions` 对。 |
-| `summarizationModel` | 否（默认 `''`） | 与 `summarizationProvider` 一起设置；空对会解析为最新已记录请求目标，再回退到 `AgentOptions` 对。 |
-| `maxTokens` | 否（默认 `8192`） | 摘要调用的提供方生成上限；可包含推理 token。 |
-| `compactionRetries` | 否（默认 `1`） | 压力仍高于阈值时，在首次尝试后进行的额外尝试次数。 |
-| `maxOverflowRetries` | 否（默认 `1`） | 规范上下文窗口溢出后的最大重试次数；`0` 只禁用恢复。 |
-| `modelPolicies` | 否（默认 `[]`） | 精确的 `{ provider, model, ...partialPolicy }` 覆盖；匹配使用两个字段，不依赖 `listModels()`。 |
-| `auto` | 否（默认 `true`） | 注册步骤边界压力与溢出恢复 listener。设为 `false` 则仅手动执行。 |
+默认设置下你会获得四种行为：会话向模型上下文上限增长时自动压缩；提供方确认上下文溢出错误后的恢复（先压缩再重试该请求）；通过 `/compact` 命令按需压缩；以及——挂载修剪器时——压缩前对超大工具输出的修剪。
 
-每个 `modelPolicies` 配置项都接受上述策略字段，但不接受 `auto` 和 `modelPolicies` 自身。如果配置项提供任意一个保留字段，就替换默认策略的保留选择；否则继承保留设置。摘要提供方／模型在每个配置项内仍然成对。
+### 最小可用组合
 
-适配器可能无法为有效动态路由返回容量，已解析容量也可能暴露无效的绝对保留预算。此时手动压力检查会抛出目标特定配置错误；自动 listener 会对该精确目标警告一次，并携带完整历史继续。不相关的操作性失败仍会独立可见。规范提供方溢出仍会尝试恢复，因为提供方已确立压缩的必要性。
+挂载会话存储、token 测量、可选修剪器、本后端，以及可选的按需命令：
 
-## 用法
-
-`BasicCompactionEngine` 需要 `ctx.llm`、`ctx.tokenMeter` 和 `ctx.sessions`。以下组合从其宿主接收 `ctx.llm`，并安装另外两项服务：
-
-```ts
-import type { Context } from '@deepseek-ai/cordis'
-import { BasicCompactionEngine } from '@deepseek-ai/dsh-compaction-basic'
-import SessionStore from '@deepseek-ai/dsh-session'
-import TokenMeter from '@deepseek-ai/dsh-token-meter'
-
-export const name = 'compaction-basic'
-export const inject = ['llm']
-
-export function apply(ctx: Context): void {
-  ctx.plugin(SessionStore)
-  ctx.plugin(TokenMeter)
-  ctx.plugin(BasicCompactionEngine)
-}

+- name: '@deepseek-ai/dsh-compaction-tool-result-pruner'
+- name: '@deepseek-ai/dsh-compaction-basic'
+- name: '@deepseek-ai/dsh-command-compact'
 ```
 
-加载插件会注册 `ctx.compaction`。在该插件之前添加同级 [`dsh-compaction-tool-result-pruner`](../compaction-tool-result-pruner/README.zh.md) 以启用可选的不依赖模型的处理阶段。当 `auto: true`（默认）时，它会在 token 压力下自动压缩。同级 [`dsh-command-compact`](../command-compact/README.zh.md) 调用 `ctx.compaction.compactNow(...)`；编程调用方也可以直接使用任一 seam 操作。

+你可以通过观察会话越过本来会溢出的位置继续工作、以及运行 `/compact` 立即压缩一次来确认成功。如果组合缺少 LLM、会话存储或 token 测量，插件会加载失败。同一个后端可以服务上下文大小不同的模型；用按模型覆盖为每条路由设置各自的阈值与保留：

+### 调整压缩开始的时机
+
+所有设置都可选。默认在已路由模型上下文窗口的 80% 处开始压缩，并逐字保留最新的 16%；下表是完整的策略面，生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-compaction-basic)是穷尽式真源。
+

+| `retainRatio` | `0.16` | 以已路由上下文窗口的一部分表示逐字保留的近期对话；与 `retainTokens` 互斥。 |
+| `retainTokens` | — | 逐字保留的近期对话绝对预算；与 `retainRatio` 互斥，并且必须低于已解析阈值。 |

+| `compactionRetries` | `1` | 压力仍高于阈值时，在首次压缩后进行的额外尝试次数。 |
+| `maxOverflowRetries` | `1` | 已确认上下文窗口溢出后的最大重试次数；`0` 只禁用恢复。 |

+| `auto` | `true` | 启用自动压缩与溢出恢复；设为 `false` 则仅手动执行。 |
+
+配置错误会快速失败：未知设置、重复的按模型覆盖、两种保留形式同时出现，或比例保留量不低于阈值，都会在加载时拒绝插件。任何绝对 `retainTokens` 预算——顶层或按模型——不低于其阈值时，都会在该模型首次使用时失败，因为该比较需要模型的上下文大小。
+
+### 压缩运行时会发生什么
+
+最旧的平衡范围会被替换为一条摘要消息，近期尾部保持逐字不变；对话从摘要继续。操作会报告压缩了多少历史项以及估算释放的 token 数。如果没有任何内容可以安全压缩——例如整个对话就是一个不可分单元——则不会有任何改变，也不会向会话日志写入任何内容。如果没有模型可以撰写摘要（既未配置目标，也还没有已路由请求），压缩会失败并给出清晰错误，提示你配置摘要提供方与模型，或先路由一次请求。
+
+### 通过 /compact 按需压缩
+
+挂载 `dsh-command-compact` 后，在聊天 UI 中输入 `/compact` 即可立即压缩，即使未达到压力阈值。命令会报告压缩了多少历史项以及估算节省的 token 数。当 agent 正在轮次中或压缩已在运行时，`/compact` 会报告压缩暂不可用；运行期间你发送的提示词会被接受，并在压缩结束后才开始。
+
+### 修剪超大工具输出
+
+在本包之前挂载 `dsh-compaction-tool-result-pruner`，即可在压缩过程中修剪超大工具结果。修剪不发起模型调用，并可能完全省去摘要：当修剪后的对话在阈值之内时，压缩会跳过摘要。修剪只在压缩触发条件满足后运行——低于压力的对话绝不会被触碰。

+## 理解实现
+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释后端背后的设计决策；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+该后端建立在四项承诺之上：
+
+- **一个测量服务为每个决策定价。** 单例 `ctx.tokenMeter` 会在同一个已消费日志 revision 上测量最新规范已记录 envelope 与当前表层。路由适配器声明请求图片定价时，meter 会将其应用于图片历史。压力、近期尾部保留、范围选择与缩减验证使用同一套路由定价的节点数值；已记录的替换影子价仍使用与路由无关的启发式规则，使纯投影 fold 保持一致。
+- **日志记录的标记对就是事务。** 所有入口点共享一个先记录标记的区域事务：验证范围与活动锁，同步追加 `compaction/start`，准备并等待摘要，重新验证，再追加 `compaction/summary` 与替换，最后恰好进行一次闭合尝试。自动调用与显式范围调用要求数字标识的开放轮次归属与整个表层稳定；`compactNow()` 会预留空闲接纳，使用 `turn: null`，允许所选 span 之外追加仅追加上下文，flush 每次已闭合尝试，并在 `finally` 中释放接纳预留。
+- **摘要复用提供方的热前缀。** 逐字回放上次已路由请求的系统提示词、工具与已遮蔽区域消息，使辅助调用成为会话的真正前缀，因此只有尾随指令与摘要输出未缓存。
+- **`summarize()` 是唯一的子类钩子。** 基于模板或远程摘要器的子类可以覆盖它，同时压力、保留、被引用的源事件、缩减验证与已遮蔽 token 计量仍由 token meter 负责。
+
+### 自动触发与溢出恢复
+
+当 `auto: true` 时，串行 `agent/pre-step` listener 会在请求派生前检查压力：它通过 `ctx.tokenMeter` 为最新持久路由请求 envelope 定价，当压力越过路由模型的阈值时，先剪枝，再在保留已定价近期尾部的同时摘要最旧的平衡范围。`agent/request-error` listener 响应提供方确认的 `CONTEXT_WINDOW_EXCEEDED`：它绕过常规阈值与保留策略，尝试一次最大平衡头部缩减，并且只在表层替换 generation 前进后才授权重试。取消全程保持最终决定权。
+
+压力策略从拥有持久路由的适配器解析容量。适配器无法为有效动态路由返回容量时，手动压力路径会抛出目标特定配置错误；自动 listener 会对该精确目标警告一次，并携带完整历史继续。
+
+### 摘要机制
+
+直接 `ctx.llm.stream()` 调用使用已配置的提供方／模型对与上限，回退到最新已记录请求目标，然后再回退到 `AgentOptions` 对，而不运行仅用于 agent loop 的 `agent/request` 扩展点。该调用逐字回放会话自身的系统提示词、工具与已遮蔽区域消息——包括所选适配器必须解析或明确拒绝的图片引用——并将压缩指令作为最后一条 user 消息追加，从而复用提供方的热前缀 cache，而非使它失效。调用将 `GenerateOptions.purpose` 设为 `compaction`；只有返回文本进入检查点，推理与工具调用都会被排除。图片输出会以 `UNSUPPORTED_CONTENT` 失败，而不是消失。替换 user 消息用 `<compacted-summary>` 标签框定摘要；原始摘要保留在 `compaction/summary` 事件上。
+
+### 区域事务
+
+事务验证表层范围与持久锁，追加 `compaction/start`，通过钩子生成摘要，重新验证稳定性（自动调用要求整个表层、手动调用只要求所选范围），拒绝不缩小源内容的摘要，追加 `compaction/summary` 与替换 `user/message`，并恰好进行一次 `compaction/end` 尝试。活动的未匹配 start 是持久锁：位于较新 `session/end-seed` 之前的未匹配标记是先前生命周期留下的陈旧证据，不会阻塞；位于该边界之后的标记报告 `busy`。闭合失败会有意留下阻塞性的未匹配标记。完成清理与持久化后，取消仍具有最终决定权。
+
+### 配置解析
+
+`resolveConfig` 验证并分离默认值，`resolveTargetPolicy` 将精确的提供方／模型覆盖合并到默认值之上，`resolveCompactSpec` 使用适配器拥有的上下文容量将合并后的策略缩放为具体 token 预算。策略解析绝不咨询模型发现（`listModels()`）；只有持久路由的容量才重要。

 # @deepseek-ai/dsh-compaction-tool-result-pruner
 
 English | [中文](README.zh.md)
 
-The replay-safe model-free pruning service (`ctx.toolResultPruner`). It rewrites over-budget `tool/result` surface nodes to a bounded head, a fixed omission marker, and a bounded tail while retaining the full original event in the append-only session log.
+## Summary
 
-This is a concrete companion to [`dsh-compaction-basic`](../compaction-basic/README.md), not a compaction backend or model-facing tool. Compact-basic reads it through optional `ctx.get('toolResultPruner')`, so either package remains independently composable.
+`dsh-compaction-tool-result-pruner` keeps the context window from filling up with oversized tool output. When compaction is about to run, it trims each over-budget tool result to a bounded head, a short "middle pruned" marker, and a bounded tail, while the full original result stays in the session log for exact replay and inspection. Trimming makes no model call and can clear token pressure on its own, so compaction may skip the summary entirely. It only runs when a compaction trigger qualifies — a below-pressure conversation is never touched. Character budgets are a heuristic; the token meter decides whether pressure was actually relieved.
 
-## Service API
+## Table of Contents
 
-`pruneSession(session)` scans one stable snapshot of the current surface. Every over-budget tool result is replaced by one newly appended `tool/result` carrying `{ surfaceOp: { op: 'replace', start: originalSeq, end: originalSeq }, sourceEventSeqs: [originalSeq] }`. The replacement spreads the complete original data and changes only `content`, preserving `turn`, `step`, `callId`, error fields, `meta`, and later data additions. The original event remains available for persistence, replay, and exact-log inspection.

+- [Known Limitations and Deferred Work](#known-limitations-and-deferred-work)
+- [Dev Note](#dev-note)
 
-The method throws synchronously when the session rejects a replacement. Replacements committed earlier in the pass remain durable.
+-----
 
-`measureContent(blocks)` counts Unicode code points in `text` blocks. `pruneContent(blocks)` returns the bounded replacement or `null` when content is already within the threshold. Non-text blocks are retained at their original relative positions; text slicing never splits a UTF-16 surrogate pair, though it can split a multi-code-point grapheme cluster.
+<a id="use-this-package"></a>
+## Use this package
 
-Every emitted result has exactly the configured head budget, fixed marker, and tail budget in text code points, is no larger than `thresholdChars`, and is strictly smaller than the triggering input. A second pass therefore emits no replacement.
+Mount this package next to `dsh-compaction-basic` when tool output regularly dominates the conversation window. Trimming changes what the model sees — shorter results — and gives compaction less history to condense.
 
-## Config
+### Smallest working composition
 
-Unrecognized keys fail at plugin construction. Resolved config is detached and deeply immutable.
+Mount token measurement, this package, and the backend in this order:
 
-| Key | Required | Meaning |
-|---|---|---|
-| `thresholdChars` | no (default `8192`) | Prune when combined text exceeds this many Unicode code points. |
-| `headChars` | no (default `4096`) | Leading Unicode code points retained. |
-| `tailChars` | no (default `1024`) | Trailing Unicode code points retained. |
-
-All values are integers; the threshold is positive and head/tail are non-negative. `headChars + marker + tailChars` must fit within `thresholdChars`, so a valid configuration can prune every over-budget result without growth or repeated rewriting.
-
-## Usage
-
-```ts
-import type { Context } from '@deepseek-ai/cordis'
-import ToolResultPruner from '@deepseek-ai/dsh-compaction-tool-result-pruner'
-
-export function apply(ctx: Context): void {
-  ctx.plugin(ToolResultPruner)
-}
+```yaml
+- name: '@deepseek-ai/dsh-token-meter'
+- name: '@deepseek-ai/dsh-compaction-tool-result-pruner'
+- name: '@deepseek-ai/dsh-compaction-basic'
 ```
 
+With these rows, oversized tool results are trimmed automatically as part of condensation. You can verify success by checking that future requests show the trimmed results; the full originals remain in the session log.
+
+### What gets trimmed
+
+Every tool result whose text exceeds the threshold is replaced by a trimmed version: the configured head, a short "middle pruned" marker, and the configured tail. Rich content such as images and structured blocks keeps its order. The replacement keeps the tool call, step, errors, and metadata — only the text content changes. If a replacement cannot be recorded, the run fails and the trims already applied stay in place.
+
+### Setting the size limits
+
+All settings are optional; the defaults trim any result with more than 8,192 text characters to its first 4,096 plus its last 1,024, joined by the marker. The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-compaction-tool-result-pruner) is the exhaustive source.
+
+| Field | Default | Meaning |
+|---|---|---|
+| `thresholdChars` | `8192` | Trim when combined text exceeds this many Unicode code points. |
+| `headChars` | `4096` | Leading Unicode code points retained. |
+| `tailChars` | `1024` | Trailing Unicode code points retained. |
+
+Character counts are Unicode code points, so slicing never splits an emoji pair, though a multi-character grapheme can still be cut. The head plus the marker plus the tail must fit within the threshold, so a valid configuration trims every over-budget result without growth or repeated rewriting. An unknown setting rejects the plugin at construction.
+
+### When trimming runs
+
+Trimming only runs when a compaction trigger qualifies: `dsh-compaction-basic` invokes it after pressure or overflow is confirmed, before it selects what to condense. Below pressure nothing is trimmed, and trimming itself makes no model call.

+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the pruner; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The pruner is built on three commitments:
+
+- **Deterministic one-pass convergence.** Slicing is by Unicode code point with fixed budgets, so every emitted result has exactly the configured head, marker, and tail in text code points, is no larger than `thresholdChars`, and is strictly smaller than the triggering input.
+- **Replay-safe replacement.** The original event remains in the append-only log; the replacement cites it through `sourceEventSeqs`, so replay recovers the exact input that produced the pruned result.
+- **The shadow-price protocol.** `compaction/prune` immediately precedes its replacement, pricing the exact replaced range through the injected token meter so pure consumers subtract it without per-node state — the shared protocol documented on the `compaction/prune` event.
+
+### Pruning mechanics
+
+Pruning measures `text` blocks by Unicode code point (non-text blocks cost zero), produces a bounded replacement — or none when content is already within budget — and swaps each over-budget tool result for one newly appended `tool/result` that replaces the original event and cites it through `sourceEventSeqs`, immediately preceded by a `compaction/prune` shadow-price event. A session that rejects a replacement fails the run synchronously; replacements committed earlier in the pass stay durable. Non-text blocks keep their original relative positions, and slicing never splits a UTF-16 surrogate pair. Exact signatures are in [`src/index.ts`](src/index.ts).
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `ToolResultPruner` service, `pruneSession` / `pruneContent` / `measureContent` |
+| [`src/config.ts`](src/config.ts) | `PRUNE_MARKER`, defaults, code-point counting, budget validation |
+| [`src/types.ts`](src/types.ts) | `ToolResultPruneConfig`, `ResolvedConfig`, `PrunedEntry`, `PruneResult` |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; replacements are observable in the session log) |

-可安全回放、不依赖模型的剪枝服务（`ctx.toolResultPruner`）。它会将超出预算的 `tool/result` 表层节点改写为长度受限的头部、固定省略标记和长度受限的尾部，同时在仅追加会话日志中保留完整原始事件。
+## 概述
 
-这是 [`dsh-compaction-basic`](../compaction-basic/README.zh.md) 的具体配套服务，不是压缩（compaction）后端或面向模型的工具。Compact-basic 通过可选的 `ctx.get('toolResultPruner')` 读取它，因此这两个包仍可各自独立组合。
+`dsh-compaction-tool-result-pruner` 防止上下文窗口被超大工具输出填满。压缩即将运行时，它会把每个超出预算的工具结果修剪为长度受限的头部、简短的「middle pruned」标记与长度受限的尾部，同时完整原始结果仍保留在会话日志中，可供精确回放与检查。修剪不发起模型调用，并可能自行清除 token 压力，因此压缩可能完全跳过摘要。它只在压缩触发条件满足后运行——低于压力的对话绝不会被触碰。字符预算只是启发式；token meter 负责判定压力是否真的得到缓解。
 
-## 服务 API
+## 目录
 
-`pruneSession(session)` 会扫描当前表层的一个稳定快照。每个超出预算的工具结果都会被一个新追加的 `tool/result` 替换，其携带 `{ surfaceOp: { op: 'replace', start: originalSeq, end: originalSeq }, sourceEventSeqs: [originalSeq] }`。替换会展开完整原始数据，只更改 `content`，保留 `turn`、`step`、`callId`、错误字段、`meta` 以及以后新增的数据字段。原始事件仍可用于持久化、回放和精确日志检查。

+- [进一步探索](#further-exploration)
+- [模型体验](#model-experience)
+- [已知限制与延期工作](#known-limitations-and-deferred-work)
+- [开发备注](#dev-note)
 
-当会话拒绝替换时，该方法会同步抛出异常。本次扫描中先前已提交的替换仍会保留。
+-----
 
-`measureContent(blocks)` 会统计 `text` 块中的 Unicode 码点。`pruneContent(blocks)` 会返回长度受限的替换；如果内容已在阈值内，则返回 `null`。非文本块保持原始相对位置；文本切片绝不会拆分 UTF-16 代理项对，但可能拆分由多个码点组成的字素簇。
+<a id="use-this-package"></a>
+## 使用本包
 
-每个发出的结果在文本码点上都精确包含已配置的头部预算、固定标记和尾部预算，不大于 `thresholdChars`，且严格小于触发输入。因此第二次扫描不会发出替换。
+当工具输出经常主导对话窗口时，在 `dsh-compaction-basic` 旁挂载本包。修剪会改变模型看到的内容——更短的结果——并让压缩有更少的历史需要压缩。
 
-## 配置
+### 最小可用组合
 
-无法识别的配置键会使插件在构造时失败。已解析配置与输入脱离，并且深度不可变。
+按此顺序挂载 token 测量、本包与后端：
 
-| 配置键 | 必填 | 含义 |
-|---|---|---|
-| `thresholdChars` | 否（默认 `8192`） | 合并文本超过此 Unicode 码点数时剪枝。 |
-| `headChars` | 否（默认 `4096`） | 保留的开头 Unicode 码点数。 |
-| `tailChars` | 否（默认 `1024`） | 保留的末尾 Unicode 码点数。 |
-
-所有值都必须是整数；阈值必须为正数，头部／尾部必须为非负数。`headChars + marker + tailChars` 之和不得超过 `thresholdChars`，因此有效配置可以剪枝每个超出预算的结果，不会增长或重复改写。
-
-## 用法
-
-```ts
-import type { Context } from '@deepseek-ai/cordis'
-import ToolResultPruner from '@deepseek-ai/dsh-compaction-tool-result-pruner'
-
-export function apply(ctx: Context): void {
-  ctx.plugin(ToolResultPruner)
-}
+```yaml
+- name: '@deepseek-ai/dsh-token-meter'
+- name: '@deepseek-ai/dsh-compaction-tool-result-pruner'
+- name: '@deepseek-ai/dsh-compaction-basic'
 ```
 
+有了这些配置行，超大工具结果会在压缩过程中自动被修剪。你可以通过检查后续请求是否显示修剪后的结果来确认成功；完整原始内容仍保留在会话日志中。
+
+### 什么会被修剪
+
+每个文本超过阈值的工具结果都会被替换为修剪版本：配置的头部、简短的「middle pruned」标记与配置的尾部。图片与结构化块等富内容保持原有顺序。替换保留工具调用、步骤、错误与元数据——只有文本内容发生变化。如果替换无法被记录，运行会失败，已应用的修剪仍会保留。
+
+### 设置大小限制
+
+所有设置都可选；默认会把文本超过 8,192 个字符的结果修剪为其前 4,096 加后 1,024 个字符，并用标记连接。生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-compaction-tool-result-pruner)是穷尽式真源。
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `thresholdChars` | `8192` | 合并文本超过此 Unicode 码点数时修剪。 |
+| `headChars` | `4096` | 保留的开头 Unicode 码点数。 |
+| `tailChars` | `1024` | 保留的末尾 Unicode 码点数。 |
+
+字符数以 Unicode 码点计，因此切片绝不会拆分 emoji 对，但多字符字素仍可能被切断。头部加标记加尾部之和必须不超过阈值，因此有效配置可以修剪每个超出预算的结果，不会增长或重复改写。未知设置会在构造时拒绝插件。
+
+### 修剪何时运行
+
+修剪只在压缩触发条件满足后运行：`dsh-compaction-basic` 在压力或溢出确认后、选择要压缩的内容之前调用它。低于压力时不会修剪任何内容，修剪本身也不发起模型调用。

+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释修剪器背后的设计决策；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+该修剪器建立在三项承诺之上：
+
+- **确定性的单次收敛。** 按 Unicode 码点以固定预算切片，因此每个发出的结果在文本码点上都精确包含已配置的头部、标记与尾部，不大于 `thresholdChars`，且严格小于触发输入。
+- **可安全回放的替换。** 原始事件保留在仅追加日志中；替换通过 `sourceEventSeqs` 引用它，因此回放可以恢复产生已剪枝结果的精确输入。
+- **影子价格协议。** `compaction/prune` 紧跟其替换，通过注入的 token meter 为被替换的精确范围定价，使纯消费方无需每节点状态即可减去它——即 `compaction/prune` 事件上记录的共享协议。
+
+### 剪枝机制
+
+剪枝按 Unicode 码点测量 `text` 块（非文本块计为零），生成长度受限的替换——内容已在预算内时则不替换——并把每个超出预算的工具结果换为一条新追加的 `tool/result`，该事件替换原始事件并通过 `sourceEventSeqs` 引用它，前面紧跟一条 `compaction/prune` 影子价格事件。会话拒绝替换时，运行会同步失败；本次扫描中先前已提交的替换仍会保留。非文本块保持原始相对位置，切片绝不会拆分 UTF-16 代理项对。精确签名见 [`src/index.ts`](src/index.ts)。

-The **`CompactionEngine`** (`ctx.compaction`) defines WHAT compaction does — decide when history is too large and summarize an older range into a single surface node — without saying HOW.
+## Summary
 
-This package owns the Service Definition role of the compaction capability, split so each role evolves (and swaps) independently:
+`dsh-compaction` lets a long session condense its older history into a single summary message, keep the recent conversation intact, and continue as if the summary had always been there — with a backend such as `dsh-compaction-basic` and the optional `/compact` command. The condensed content stays in the session log, so replaying the session reproduces the exact conversation. Reach for this package when you implement a condensation backend, build something that triggers condensation, or need to recognize condensed messages — it performs no condensation itself. Choose the shipped backend when you just want the feature working out of the box.

+## Use this package
+
+Decide first what you need. The shipped backend plus the `/compact` command give you automatic and on-demand condensation with no code; this package only matters when you extend or reimplement the feature. The sections below describe what condensation does, how to turn it on, and how to write a backend.
+
+### When to choose it
+
+Choose `dsh-compaction-basic` when a model-written summary fits your needs: you get condensation automatically as the conversation grows, and on demand through `dsh-command-compact`. Choose this package when you write a backend with a different summarizer — a fixed template or a remote service — or when you build something that triggers condensation programmatically. Do not mount it alone: without a backend nothing condenses.
+
+### What condensation looks like

+When condensation runs, the selected older span of the conversation is replaced by one summary message; recent history is untouched and the conversation continues from the summary. Condensation can be triggered automatically as token pressure builds, on demand, or over an explicit span; the result reports which history was condensed and the estimated tokens freed.
+
+### Turning condensation on
+
+Mount the shipped backend to register the condensation service, and add `dsh-command-compact` for the on-demand command:
+
+```yaml
+- name: '@deepseek-ai/dsh-compaction-basic'
+- name: '@deepseek-ai/dsh-command-compact'
+```
+
+With these two rows the feature is on: the conversation condenses automatically as it grows, and `/compact` condenses immediately on request and reports how many history items were replaced. If no backend is mounted, nothing condenses and `/compact` fails; the full dependency chain for the shipped backend is in its own README.
+
+### Implementing a backend
+
+Extend the provided base class and implement three operations: one that decides and performs condensation for an automatic trigger, one that condenses on demand, and one that condenses an explicit range of the conversation. Load your class as a plugin and it becomes the condensation service for the composition. The exact signatures, the failure rules, and the checkpoint marker every backend must produce are in the implementation section below and in the [compaction subsystem reference](../../../docs/subsystems/compaction.md).
+
+### Recognizing condensed history
+
+Messages a backend wrote as summaries carry a stable marker, so any consumer can recognize condensed history after persistence or cloning without knowing which backend produced it. The marker is exported from the package root and from a cordis-free subpath that client and wire programs can import.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the contract in API terms and the design decisions behind it; the feature-level behavior is covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The seam is built on one split and three commitments:
+
+- **Abstract contract, concrete backends.** The interface states what condensation does; providers own policy, retention, and summarization so each role evolves and swaps independently.
+- **Session and LLM vocabulary are part of the contract.** The operations act on a `Session` and the summary uses `ContentBlock`, so the Service Definition depends on `dsh-session` and `dsh-llm` despite the general cordis-only guidance — a deliberate deviation recorded in the [compaction capability-seam Agent Note](../../../.agents/notes/implemented/feature/2026-06-18-compaction-capability-seam.md).
+- **The log-recorded bracket is the lock.** `compaction/start` is appended before summarization yields and `compaction/end` releases; every failure makes exactly one close attempt, and a failed close leaves the unmatched start as the intentional busy signal.
+- **The surface is mutated exactly once.** The summary rides on a `user/message` replacement inside the bracket; all `compaction/*` events stay log-only.
+
+### Service API
+
+The contract is three abstract operations a backend implements: `compactIfNeeded` for automatic `pressure` or `context-overflow` triggers, `compactNow` for one explicit on-demand reduction, and `compactRegion` for a caller-selected surface range. Reusable request measurement is a separate service, `ctx.tokenMeter`. The exhaustive per-operation semantics live in the [compaction subsystem reference](../../../docs/subsystems/compaction.md); the exact signatures are in [`src/index.ts`](src/index.ts).
+
+A backend that summarizes through `ctx.llm.stream()` must forward the abort signal into the call's `GenerateOptions.signal`, so an abort or fiber dispose tears down the in-flight summarization. Automatic and explicit-region brackets recover their numeric owner from the open turn; manual brackets require no open turn and stamp `turn: null`.
+
+### Manual failure taxonomy
+
+Expected manual failures throw `ManualCompactionError` with a stable `code` from a small closed set; only failures after the `compaction/start` marker are recorded — as a `compaction/end` carrying the error — while a `busy` rejection or pre-start cancellation leaves no record. The per-code semantics live in the [compaction subsystem reference](../../../docs/subsystems/compaction.md).
+
+<a id="tool-pairing-boundaries"></a>
+### Tool-pairing boundaries
+
+The Service Definition exports `toolPairingBalancedBefore(session, seq)` and `toolPairingBalancedAfter(session, seq)` for snapping and validating compaction edges. A safe edge has no unanswered assistant tool call crossing it. Each helper validates that the event sequence is in the current surface and answers from balances cached per cut in surface order, so repeated checks read no events; a replace generation rebuilds the cache, and missing seqs or an orphan `tool/result` reject as corrupt surface state.
+
+### The surface contract
+
+`SurfaceEventType` is a closed union — only `user/message`, `assistant/message`, and `tool/result` may carry `surfaceOp`, so a `compaction/*` event cannot appear on the surface. A successful backend run instead brackets the operation in the log: it appends `compaction/start` (log-only) to acquire the lock, summarizes the range, appends the log-only `compaction/summary` record, replaces the selected span with one `user/message` carrying the summary — the only surface mutation — and appends `compaction/end` (log-only) to release the lock.
+
+The replacement sits inside the lock bracket, so a crash between `compaction/start` and `compaction/end` leaves a detectable orphaned lock rather than a `compaction/end` that falsely claims success. `deriveMessages()` renders the summary as a user-role message followed by the retained nodes; the shadowed events stay in the raw log, so replay is deterministic. The per-event payloads are enumerated in the [compaction subsystem reference](../../../docs/subsystems/compaction.md).
+
+### Source map
+
+| File | Role |
 |---|---|
-| `@deepseek-ai/dsh-compaction` (this) | Service Definition: abstract service + `compaction/*` events + `CompactionResult` + correlated checkpoint-source constructor + tool-pairing boundary helpers |
-| `@deepseek-ai/dsh-compaction-basic` | Service Provider: `ctx.tokenMeter` pressure + token-budget retention + `llm.stream()` summarization |
-| `@deepseek-ai/dsh-command-compact` | Consumer: the human `/compact` command over `ctx.compaction.compactNow()` |
+| [`src/index.ts`](src/index.ts) | Plugin entry: abstract `CompactionEngine`, `CompactionTrigger`, `ManualCompactionError`, `ctx.compaction` merge |
+| [`src/types.ts`](src/types.ts) | `CompactionResult` and the declaration-merged `compaction/*` session events |
+| [`src/tool-pairing.ts`](src/tool-pairing.ts) | Per-session cut-balance cache behind the two boundary helpers |
+| [`src/checkpoint.ts`](src/checkpoint.ts) | Cordis-free checkpoint source constructor and predicate (`./checkpoint` leaf) |
+| [`src/brand.ts`](src/brand.ts) | `CompactionId` branded identity |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion: validates the `compaction/start`→`summary`→`end` bracket, its owner-turn enclosure, and checkpoint correlation |
 
-Unlike the bash seam, this Service Definition depends on `@deepseek-ai/dsh-session` and `@deepseek-ai/dsh-llm` — the contract's verbs are defined over a `Session` and its output is the `ContentBlock` vocabulary, so they cannot be expressed without naming those packages. That deviation from the "Service Definition depends only on cordis" guidance is intentional and recorded in the [compaction capability-seam Agent Note](../../../.agents/notes/implemented/feature/2026-06-18-compaction-capability-seam.md).
+### Locking and serialization
 
-## Service API (`ctx.compaction`)
+One log-recorded lock is shared by all entry points. Tail inspection finds the latest unmatched `compaction/start` and the newest `session/end-seed`; an unmatched start after that boundary is live and reports `busy`, while an older one is stale evidence from a prior process lifecycle. A live bracket cannot cross a `turn/start` or `turn/end`. The markers are lock time points, not an exclusive container: an idle `inject()` may append unrelated context between a manual start and end, so the manual path revalidates its selected span rather than demanding whole-surface equality.
 
-All three operations are **abstract** — the backend owns trigger policy, retention, event sequencing, and summarization. Reusable request measurement is a separate service, [`ctx.tokenMeter`](../../llm/token-meter/README.md), rather than part of this Service Definition.
+### Events
 
-| Member | Semantics |
-|---|---|
-| `compactIfNeeded(agent, trigger, signal)` | Consider automatic compaction for `trigger: 'pressure' \| 'context-overflow'`. A pressure trigger may apply the backend's threshold and retained-tail policy; a confirmed overflow may force a useful balanced reduction. Returns the `CompactionResult`, or `null` when no safe range exists. A backend's summarization request is a direct `ctx.llm.stream()` call (not a loop step), so per-call interception happens at `llm/stream`. |
-| `compactNow(agent, signal)` | Explicitly compact one useful balanced older span even below automatic pressure. It synchronously reserves idle turn admission before yielding, writes nothing when no useful span exists, records a standalone `compaction/* { turn: null }` attempt before summarization, and awaits its durability checkpoint before release. Expected operational failures use `ManualCompactionError`; cancellation rethrows the exact abort reason. |
-| `compactRegion(start, end, agent, signal?)` | Forcibly summarize surface nodes `[start, end]` (inclusive seqs) from `agent.session` into a single replacement node whose source comes from `compactCheckpointSource(compactionId)`. **Throws** if a compaction is already in progress, if `start`/`end` aren't surface nodes, or if `start` is positioned after `end` on the surface. The range is a SURFACE-POSITION span, not a numeric seq interval — after a prior replace lands a fresh high-seq summary node at the shadowed range's position, surface order no longer tracks seq order. |
+The `compaction/*` events extend `SessionEventMap` (merge-extensible) via declaration merging — session events, not cordis `Events`, and all log-only. The generated [persistence log event catalog](../../../docs/persistence-catalog.md) owns the per-event payloads; `compaction/prune` documents the shadow-price protocol shared with the tool-result pruner.
 
-`CompactionResult` keeps the raw summary and bookkeeping-event seqs available to callers alongside the shadowed range and token accounting; its drift-checked shape lives in the [compaction data-structure reference](../../../docs/subsystems/compaction.md#compactionresult).
+</details>
 
-`compactIfNeeded` and `compactNow` take a required `signal`; `compactRegion`'s is optional. A backend that summarizes via `ctx.llm.stream()` **must** forward it into the call's `GenerateOptions.signal`, so an abort or fiber dispose tears down the in-flight summarization. Automatic and explicit-region brackets recover their numeric owner from the currently open turn. Manual brackets require no open turn and stamp `turn: null`.
+-----
 
-`ManualCompactionError.code` is the closed set `busy | changed | summary | commit | persistence`. `changed` and `summary` mean the selected conversation surface was not replaced, but their failed attempt is still recorded in the session log. `commit` is deliberately neutral about partial mutation, and `persistence` means the in-memory bracket closed but its explicit flush failed.

+Read these pages when the package-level contract is not enough; they move from the shared vocabulary to the shipped backend and the decision evidence.
 
-The Service Definition exports `toolPairingBalancedBefore(session, seq)` and `toolPairingBalancedAfter(session, seq)` for snapping and validating compaction edges. A safe edge has no unanswered assistant tool call crossing it. Each helper validates that the event sequence is in the current surface and answers from balances cached per cut in surface order.
+- [Compaction subsystem reference](../../../docs/subsystems/compaction.md) — the condensation vocabulary, results, and generated service API.
+- [Compaction basic backend](../compaction-basic/README.md) — the shipped backend that condenses automatically and on demand.
+- [Tool-result pruner](../compaction-tool-result-pruner/README.md) — the optional companion that trims oversized tool outputs first.
+- [Human /compact command](../command-compact/README.md) — the on-demand trigger for condensation.
+- [Token meter](../../llm/token-meter/README.md) — the measurement service that decides when to condense.
+- [Compaction capability-seam Agent Note](../../../.agents/notes/implemented/feature/2026-06-18-compaction-capability-seam.md) — the split and the session/llm dependency rationale.
 
-The private per-session cache is keyed by `session.surface.replaceGeneration` and the processed surface-entry count. An unchanged generation extends the fold with unseen tail entries only; a log-only append with no new surface entry does no event reads, while a replacement generation rebuilds current membership and balances. Missing event seqs and a `tool/result` without a preceding open call reject as corrupt surface state.
-
-## Surface contract
-
-`SurfaceEventType` is a closed union — only `user/message`, `assistant/message`, and `tool/result` may carry `surfaceOp`. A `compaction/*` event therefore **cannot** appear on the surface. A successful compaction instead:
-
-1. appends `compaction/start` (log-only) — acquires the lock,
-2. summarizes the range,
-3. appends `compaction/summary` (log-only) with the summary, range, shadowed seqs, token count, and provider/model call envelope,
-4. appends a single `user/message` with `source: compactCheckpointSource(compactionId, sourceCommandId?)` and `surfaceOp: { op: 'replace', start, end }` carrying the summary — **the only surface mutation in this operation**,
-5. appends `compaction/end` (log-only) — releases the lock.
-
-The surface mutation (step 4) sits **inside** the lock bracket: `compaction/end` is the last event, so the lock is never released before the mutation lands. A crash between `compaction/start` and `compaction/end` therefore leaves a detectable orphaned lock (a `compaction/start` with no matching `compaction/end`) rather than a `compaction/end` that falsely claims compaction finished while the surface was never shadowed.
-
-The marker pair names lock acquisition and release, not an exclusive event container. An idle `inject()` may append unrelated context between a manual start and end while summarization is pending. Manual stability therefore revalidates the selected span rather than demanding whole-surface equality; the positional replacement leaves that injected context visible after the checkpoint. Automatic compaction keeps whole-surface equality inside its active turn.
-
-`deriveMessages()` then renders the summary as a user-role message followed by the retained nodes. The shadowed events remain in the raw log, so replay is deterministic.
-
-## Blocking
-
-Compaction is serialized by one log-recorded lock shared by all entry points. Tail inspection independently finds the latest unmatched `compaction/start` and the newest `session/end-seed`. An unmatched start after that boundary is live and reports `busy`; an older unmatched start is stale evidence from a prior process lifecycle and does not block. The same end-seed transition clears the invariant companion's replay trace. A live bracket cannot cross a `turn/start` or `turn/end`; during adoption, repair boundaries in the inherited prefix remain replayable when the later end-seed proves their open bracket stale.
-
-The lock is the durable bracket, not a `WeakSet`, wrapper mutex, or client-side anchor. `compaction/start` is appended synchronously before summarization yields. Every later failure makes exactly one `compaction/end { error }` attempt; if that close append itself fails, the unmatched start remains the intentional busy signal and no flush is attempted. A successfully closed manual attempt is flushed even when it reports `changed` or `summary`, preserving the recorded attempt before turn admission is released.
-
-## Events
-
-The `compaction/*` events extend `SessionEventMap` (merge-extensible) via declaration merging — they are session events, not cordis `Events`, and all three are log-only (no `surfaceOp`). Per-event payloads and semantics are in the generated [persistence log event catalog](../../../docs/persistence-catalog.md).
-
-## Implementing a backend
-
-Subclass `CompactionEngine`, implement `compactIfNeeded`, `compactNow`, and `compactRegion`, and load the subclass as a plugin — it registers as `ctx.compaction`. Every successful backend creates its replacement user message source with `compactCheckpointSource(compactionId, sourceCommandId?)`; the required `compactionId` correlates the checkpoint with its `compaction/*` transaction, while `isCompactCheckpointSource()` recognizes the marker after persistence or cloning without depending on backend identity. A template- or model-backed implementation can live as a sibling package without changing callers or the shared token meter.
-
-## Recognizing a checkpoint outside the host program (`./checkpoint`)
-
-`compactCheckpointSource()`, `CompactionCheckpointSource`, and `isCompactCheckpointSource()` are declared on the `@deepseek-ai/dsh-compaction/checkpoint` subpath and re-exported from the root, so host-side consumers keep reading them from the root. The constructor requires the owning `CompactionId`, preventing backends from writing an uncorrelated marker that the package invariant must reject. The leaf imports no cordis and declares no module augmentation (the [`dsh-commands/brand`](../../interaction/commands/README.md) shape), which is what lets a client or wire program name the checkpoint source: the package **root** cannot enter such a program at all, because it reaches `dsh-session`'s root and that `Context` merge declares the host `sessions` service against the client's own (`TS2717` — one program per side, per [development.md](../../../docs/development.md#typescript-project-layout)). The web client's transcript adapter pins its plugin literal to the leaf's source type, so renaming the plugin id there is a compile error here.

 [English](README.md) | 中文
 
-**`CompactionEngine`**（`ctx.compaction`）定义压缩（compaction）做什么，即判定历史记录是否过大，并将较早范围摘要为单个表层节点，但不规定如何实现。
+## 概述
 
-本包承担压缩能力的 Service Definition 角色，因此各角色均可独立演进，也可独立替换：
+`dsh-compaction` 让长时会话把较早历史压缩（compaction）成一条摘要消息、保持近期对话不变，并像摘要一直存在那样继续下去——配合 `dsh-compaction-basic` 之类的后端与可选的 `/compact` 命令即可实现。被压缩的内容仍保留在会话日志中，因此回放会话可以还原出完全相同的对话。当你实现压缩后端、构建触发压缩的组件，或需要识别压缩后的消息时，才需要本包——它本身不执行任何压缩。只想开箱即用地获得该功能时，请选择随附后端。
 
-| 包 | 职责 |
-|---|---|
-| `@deepseek-ai/dsh-compaction`（本包） | Service Definition：抽象服务 + `compaction/*` 事件 + `CompactionResult` + 关联检查点源构造函数 + 工具配对边界 helper |
-| `@deepseek-ai/dsh-compaction-basic` | Service Provider：`ctx.tokenMeter` 压力 + token 预算保留 + `llm.stream()` 摘要 |
-| `@deepseek-ai/dsh-command-compact` | Consumer：面向人类的 `/compact` 命令，基于 `ctx.compaction.compactNow()` 实现 |
+## 目录
 
-与 bash seam 不同，该 Service Definition 依赖 `@deepseek-ai/dsh-session` 和 `@deepseek-ai/dsh-llm`。约定的动词基于 `Session` 定义，其输出使用 `ContentBlock` 词汇，因此无法在不指名这些包的情况下表达。这项对「Service Definition 只依赖 cordis」指引的偏离是有意的，并记录在 [压缩能力 seam Agent Note](../../../.agents/notes/implemented/feature/2026-06-18-compaction-capability-seam.zh.md) 中。

-## 服务 API（`ctx.compaction`）
+-----
 
-三个操作都是**抽象方法**：触发策略、保留、事件顺序与摘要均属于后端。可复用的请求测量是独立服务 [`ctx.tokenMeter`](../../llm/token-meter/README.zh.md)，而非本 Service Definition 的一部分。
+<a id="use-this-package"></a>
+## 使用本包
 
-| 成员 | 语义 |
-|---|---|
-| `compactIfNeeded(agent, trigger, signal)` | 根据 `trigger: 'pressure' \| 'context-overflow'` 判断是否需要自动压缩。压力触发可应用后端的阈值与保留尾部策略；已确认溢出可强制进行有效的平衡缩减。返回 `CompactionResult`，无安全范围时则返回 `null`。后端摘要请求是直接的 `ctx.llm.stream()` 调用（不是 agent loop（智能体循环）步骤），因此每次调用都可在 `llm/stream` 处拦截。 |
-| `compactNow(agent, signal)` | 即使未达到自动压力，也显式压缩一段有效、平衡的较早范围。该操作会在让出控制权前同步预留空闲轮次接纳；没有有效范围时不写入任何内容；在摘要前记录独立的 `compaction/* { turn: null }` 尝试；释放预留前等待其持久性检查点。预期操作失败使用 `ManualCompactionError`；取消会原样重新抛出 abort 原因。 |
-| `compactRegion(start, end, agent, signal?)` | 强制将表层节点 `[start, end]`（包含两端 seq）从 `agent.session` 摘要为单个替换节点，其源由 `compactCheckpointSource(compactionId)` 创建。如果压缩已在进行、`start`／`end` 不是表层节点，或 `start` 在表层上位于 `end` 之后，则**抛出异常**。该范围是表层位置范围，不是数值 seq 区间：在之前的 replace 将新生成的高 seq 摘要节点放到已遮蔽范围的位置之后，表层顺序不再跟随 seq 顺序。 |
+先确定你需要什么。随附后端加 `/compact` 命令即可零代码获得自动与按需压缩；只有在你扩展或重实现该功能时才需要本包。以下各节说明压缩做什么、如何启用，以及如何编写后端。
 
-`CompactionResult` 向调用方保留原始摘要与记录操作过程的事件 seq，同时保留已遮蔽范围与 token 计量；其结构由漂移检查保障，定义见 [压缩数据结构参考](../../../docs/subsystems/compaction.zh.md#compactionresult)。
+### 何时选择
 
-`compactIfNeeded` 和 `compactNow` 必须传入 `signal`；`compactRegion` 的该参数可选。通过 `ctx.llm.stream()` 摘要的后端**必须** 将它转发到调用的 `GenerateOptions.signal`，因此 abort 或 fiber dispose（资源释放）会停止进行中的摘要。自动和显式范围标记对会从当前打开的轮次恢复其数字形式归属。手动标记对不要求存在打开的轮次，并标记 `turn: null`。
+当模型撰写的摘要符合需求时，选择 `dsh-compaction-basic`：会话增长时自动压缩，并可通过 `dsh-command-compact` 按需压缩。当你需要不同的摘要方式——固定模板或远程服务——或构建以编程方式触发压缩的组件时，选择本包。不要单独挂载它：没有后端就什么都不会压缩。
 
-`ManualCompactionError.code` 是封闭集合 `busy | changed | summary | commit | persistence`。`changed` 和 `summary` 表示所选会话表层未被替换，但日志仍会记录失败尝试。`commit` 有意不判断是否发生了部分变更；`persistence` 表示内存中的 bracket 已闭合，但显式 flush 失败。
+### 压缩后会发生什么
+
+压缩运行时，所选较早范围的对话会被替换为一条摘要消息；近期历史不受影响，对话从摘要继续。压缩可以由 token 压力自动触发、按需触发，或针对显式范围触发；结果会报告压缩了哪些历史以及估算释放的 token 数。
+
+### 启用压缩
+
+挂载随附后端以注册压缩服务，并添加 `dsh-command-compact` 获得按需命令：
+
+```yaml
+- name: '@deepseek-ai/dsh-compaction-basic'
+- name: '@deepseek-ai/dsh-command-compact'
+```
+
+有了这两行配置，功能即已开启：会话增长时自动压缩，`/compact` 收到请求后立即压缩并报告替换了多少历史项。如果未挂载后端，什么都不会压缩，`/compact` 也会失败；随附后端的完整依赖链见其自身 README。
+
+### 实现后端
+
+继承提供的基类并实现三个操作：一个针对自动触发决定并执行压缩，一个按需压缩，一个压缩对话的显式范围。把你的类作为插件加载，它就会成为该组合的压缩服务。精确签名、失败规则以及每个后端必须生成的检查点标记，见下方实现章节与[压缩子系统参考](../../../docs/subsystems/compaction.zh.md)。
+
+### 识别压缩后的历史
+
+后端写入的摘要消息带有稳定标记，因此任何消费方都能在持久化或克隆后识别压缩历史，而无需知道是哪个后端生成的。该标记从包根导出，也从一个无 cordis 依赖的子路径导出，客户端与 wire 程序均可导入。

+<details>
+<summary>实现细节——点击展开</summary>
+
+本节以 API 术语解释约定及其背后的设计决策；功能层面行为见[使用本包](#use-this-package)。
+
+### 设计理念
+
+该 seam 建立在一个拆分与三项承诺之上：
+
+- **抽象约定，具体后端。** 接口规定压缩做什么；提供方拥有策略、保留与摘要，因此各角色可独立演进、独立替换。
+- **会话与 LLM 词汇是约定的一部分。** 操作作用于 `Session`，摘要使用 `ContentBlock`，因此尽管有通用的 cordis-only 指引，Service Definition 仍依赖 `dsh-session` 与 `dsh-llm`——这是一项有意的偏离，记录在[压缩能力 seam Agent Note](../../../.agents/notes/implemented/feature/2026-06-18-compaction-capability-seam.zh.md) 中。
+- **日志记录的标记对就是锁。** `compaction/start` 在摘要让出控制权之前追加，`compaction/end` 释放；每次失败都恰好进行一次闭合尝试，闭合失败会留下未匹配 start 作为有意的 busy 信号。
+- **表层只变更一次。** 摘要承载在标记对内的一条 `user/message` 替换上；所有 `compaction/*` 事件仅写入日志。
+
+### 服务 API
+
+该约定是后端实现的三个抽象操作：`compactIfNeeded` 针对自动 `pressure` 或 `context-overflow` 触发，`compactNow` 进行一次显式按需缩减，`compactRegion` 针对调用方选择的表层范围。可复用的请求测量是独立服务 `ctx.tokenMeter`。穷尽式逐操作语义见[压缩子系统参考](../../../docs/subsystems/compaction.zh.md)；精确签名见 [`src/index.ts`](src/index.ts)。
+
+通过 `ctx.llm.stream()` 摘要的后端必须将 signal 转发到调用的 `GenerateOptions.signal`，因此 abort 或 fiber dispose（资源释放）会停止进行中的摘要。自动和显式范围标记对会从打开的轮次恢复其数字形式归属；手动标记对不要求存在打开的轮次，并标记 `turn: null`。
+
+### 手动失败分类
+
+预期手动失败会抛出 `ManualCompactionError`，携带来自小型封闭集合的稳定 `code`；只有 `compaction/start` 标记之后发生的失败才会被记录——以携带错误的 `compaction/end` 形式——而 `busy` 拒绝或 start 之前的取消不会留下记录。每个错误码的语义见[压缩子系统参考](../../../docs/subsystems/compaction.zh.md)。

-这对标记表示获取和释放锁的时间点，并非排他的事件容器。手动摘要等待期间，空闲的 `inject()` 可以在 start 与 end 之间追加不相关的上下文。因此，手动稳定性检查会重新验证所选 span，而不要求整个表层相等；位置替换会让该注入上下文在检查点之后保持可见。自动压缩则要求其活动轮次内的整个表层保持相等。
+所有入口点共享一个日志记录的锁。尾部检查会分别查找最新的未匹配 `compaction/start` 与最新的 `session/end-seed`；位于该边界之后的未匹配 start 是活动锁并报告 `busy`，更早的则是先前进程生命周期留下的陈旧证据。活动标记对不能跨越 `turn/start` 或 `turn/end`。标记是锁的时间点，而非排他容器：空闲的 `inject()` 可以在手动 start 与 end 之间追加不相关的上下文，因此手动路径重新验证其选中范围，而不要求整个表层相等。

 English | [中文](README.zh.md)
 
-Product plugins that add model-visible request context without defining a tool. `agent-instructions` is included by the default `dsh-agent-spine-demo` bundle and can be disabled through bundle config; `time-context`, `tmux-context`, `session-reference`, `file-reference`, and `file-reference-local` are opt-in.
+## Summary
+
+The context group provides plugins that add model-visible context to each request without defining any tool: workspace instruction files become guidance, `@file` mentions offer path completion, other sessions can be referenced as bounded snapshots, and the model can see the current time and the agent's tmux location. All of them are opt-in except `agent-instructions`, which ships enabled in the default `dsh-agent-spine-demo` bundle and can be disabled through bundle config. Context is durable: injected instructions and references enter session history as user-role messages, so they persist, replay, and compact like other conversation content. This page maps the group; each package README owns the per-package contract.

-在不定义工具的情况下添加模型可见的请求上下文的产品插件。`agent-instructions` 包含在默认 `dsh-agent-spine-demo` 组合包中，可通过组合包配置禁用；`time-context`、`tmux-context`、`session-reference`、`file-reference` 和 `file-reference-local` 需主动启用。
+## 概述
+
+context 组提供不定义任何工具、为每次请求添加模型可见上下文的插件：工作区指令文件成为指引，`@file` mention 提供路径补全，其他会话可以作为有界快照被引用，模型还能看到当前时间与 agent 的 tmux 位置。除 `agent-instructions`（随默认 `dsh-agent-spine-demo` 组合包发布并默认启用，可通过组合包配置禁用）外，其余全部需主动启用。上下文是持久的：注入的指令与引用以 user 角色消息进入会话历史，因此与其他对话内容一样持久、可回放、可压缩。本页是组的映射；包级约定由各包 README 负责。

-Per-session workspace instruction loading for `AGENTS.md`-compatible files. The plugin injects the initial user-global and project instruction chain into durable history, then discovers nested files and reports later changes or removals after successful filesystem tool calls.
+## Summary
 
-## Lifecycle
+`dsh-agent-instructions` loads `AGENTS.md`-compatible workspace instruction files into model context: the user-global file and the project chain reach the first request as one durable baseline, and successful `read`, `write`, or `edit` calls bring newly relevant nested files, changes, and removals into later requests. It ships enabled in the default `dsh-agent-spine-demo` bundle and can be disabled through bundle config. Everything is bounded by a byte budget: broader files are omitted before the most specific file is truncated, and an empty chain contributes nothing. There is no file watcher — external edits become visible on the next successful filesystem touch or when a resumed session reconciles its baseline.
 
-The first eligible `agent/pre-step` of each live session composes the baseline. When the downstream decision enters a nonempty first-step batch, the plugin folds the baseline into that final batch right after the claimed prompt, so the direct prompt and the durable baseline enter step 1 and reach the first request together. A rejected or empty first-step decision leaves the baseline in the agent's `next-step` inbox for a later wakeup. The loader reads `$DSH_HOME/AGENTS.md` followed by, in each directory from the project root to `agent.session.header.cwd`, every existing base candidate and then every existing local-overlay candidate. Within one directory, candidates whose content is byte-identical after trimming leading and trailing whitespace collapse to the earliest candidate in configured order, so a `CLAUDE.md` that merely duplicates its sibling `AGENTS.md` is rendered once. If a previously queued workspace context is still pending, the plugin removes and replaces that exact inbox item instead of accumulating duplicates. A resumed session retains one compatible visible baseline and appends only current-file transitions; a changed discovery, precedence, project-root, or budget identity instead folds one explicitly superseding complete baseline into the entering batch.
+## Table of Contents
 
-The plugin also observes immutable `tools/result` outcomes for successful first-party `read`, `write`, and `edit` calls. Each accepted touch checks newly reached descendant scopes and every previously loaded scope. Each configured candidate name is an independent scope in its directory: a newly present file queues an addition in the agent inbox; a changed file queues a replacement; a file that disappears or becomes a per-directory duplicate of an earlier candidate queues a removal notice. Native calls and Code Mode sub-dispatches share this path: nested touches bubble through opaque parent execution tokens until the top-level result settles, and touches produced inside an agent-loop step do not begin their asynchronous projection until the durable `step/end`. Direct tool executions outside an open step project immediately. This preserves tool-call/result/step adjacency without depending on filesystem timing. Discovery follows structured filesystem activity rather than shell `cd`, because each local bash call starts a fresh shell and parsing arbitrary shell syntax would be unreliable.

-Instruction reads use the optional `ctx.fs` provider. The plugin does not statically inject `fs`, so providerless product trees still boot and instruction loading becomes a no-op until a provider is present. It resolves each candidate and stats the result, so a final-component symlink is followed to its target: a link to a regular file loads that target's content, while a missing path or a non-file target (including a link to a directory) is a confirmed absence. A resolve or stat exception instead marks that candidate's scope temporarily unavailable. Prefix cancellation and dynamic tool cancellation propagate through resolution, metadata probes, and streaming reads. A provider failure after a file was loaded is treated as temporarily unavailable, not as proof that the file was deleted.

-Baseline instructions are durable user-role messages framed with the familiar system-reminder pattern:
+Mount this plugin when agents should work from the workspace's own instruction files. The default spine bundle already includes it with a 65,536-byte budget, so most compositions only adjust `maxBytes`; providerless trees load nothing until a filesystem provider is present.

-The following workspace instructions may be relevant to your work. Use them as guidance when applicable. More specific instructions take precedence over broader ones. They do not override system, developer, or direct user instructions.

-Instructions from: ~/.dsh/AGENTS.md
+The first request includes one durable baseline message with the user-global `$DSH_HOME/AGENTS.md` followed by the project chain — every existing candidate file from the project root down to the session working directory, in broad-to-specific order. Sibling files whose content matches after trimming render once, so a `CLAUDE.md` that duplicates its `AGENTS.md` is not repeated. After a successful `read`, `write`, or `edit` call reaches a deeper directory, the next request includes the newly applicable instruction file; a changed file replaces its content, and a file that disappears or duplicates an earlier candidate produces a removal notice.
 
-...
+### Configuration
 
-Instructions from: AGENTS.md
+The defaults suit a typical checkout: `.git` marks the project root, `AGENTS.md` and `CLAUDE.md` are the base candidates, and `AGENTS.local.md` and `CLAUDE.local.md` are additive local overlays. Only `maxBytes` is required — it caps the complete rendered baseline so each deployment chooses its prompt budget explicitly.
 
-...
-</system-reminder>
+```yaml
+- name: '@deepseek-ai/dsh-agent-instructions'
+  config:
+    maxBytes: 65536
 ```
 
-Newly reached scopes use a durable sourced `user/message`:
-
-```md
-<system-reminder>
-Additional instructions from: packages/app/AGENTS.md
-
-These instructions apply to work under `packages/app`. Use them as guidance when relevant; more specific instructions take precedence. They do not override system, developer, or direct user instructions.
-
-...
-</system-reminder>
-```
-
-A same-file edit starts with `Updated instructions from: <path>` and says to use the new content instead of the previously loaded content. When a candidate disappears or becomes a per-directory duplicate of an earlier candidate, the message is `Instructions removed: <path>` followed by `The previously loaded instructions from this file no longer apply.` Literal `</system-reminder>` text anywhere in instruction content or model-visible path, scope, and budget metadata is escaped so repository-controlled text cannot close the plugin-owned frame.
-
-The plugin owns the complete `<system-reminder>` framing, and every injected `user/message` reaches the model verbatim with no core wrapper.
-
-## State And Refresh
-
-Model-visible text contains no hidden state markers. Each baseline or dynamic context event instead carries a typed `agent-instructions` source with a list of `{ action, scope, path, digest? }` changes; a complete baseline also carries `baseline: true` and a `baselineIdentity` derived from normalized discovery, precedence, project-root, and budget configuration. A matching durable `user/message` confirms a queued baseline and its candidate versions. An entering pre-step waits for every queued projection, folds newly composed context into its final batch immediately after the claimed messages, and removes the pending inbox copy; rejection keeps the current context queued. If a listener rewrites away a claimed workspace message without entering its replacement, a later boundary recomposes the current context. Nested results aggregate successful file touches under their parent execution token, including when a later composite result is blocked; the top-level result transfers those touches either to the currently open session step or directly to the per-agent projection queue. A `step/end` releases its staged touches only after that boundary is in durable history, and serialized projections reconcile against visible session events plus the current inbox before replacing the single pending workspace context.
-
-An unchanged path and SHA-1 content digest is not injected again. A per-session, per-scope provider cache stores only `{ path, version, digest, trimmedDigest }`: when the provider's opaque `FsVersion` and the effective visible state both match, reconciliation skips the content read; a changed version triggers a bounded read and SHA-1 confirmation before any model-visible update. The `trimmedDigest` — SHA-1 over the whitespace-trimmed content — is the per-directory duplicate key, so an unchanged file can still be removed when an earlier candidate converges on its content. Resume works because SHA-1 state is persisted in the typed source, while an empty in-memory version cache merely causes one confirming read. Compaction re-arms a scope after its context event leaves the visible surface even when the cached version is unchanged. A removal is a tombstone, so a later candidate reappearance is loaded again. A model-visible change enters the source, pending state, and version cache only when its file-specific section retains at least one content byte, or when its original content is genuinely empty. Partial truncation records the complete-content digest once any content byte survives; truncation to zero remains eligible for a later touch, while a same-digest version refresh updates only the provider cache. A baseline may still publish its budget diagnostic with an empty change list. A dynamic batch with no committed change is not injected at all, and a later touch retries it.
-
-The initial baseline event itself is not rewritten. Its typed changes remain authoritative only while that event is in the visible session surface. When compaction shadows the event, the next entering pre-step composes the current baseline and records it in the same request; a successful filesystem touch can instead re-add an unchanged baseline scope or append its replacement or removal. The in-memory scope marker and provider-version cache only select and accelerate probes. At the first pre-step after resume or hot remount, a compatible visible baseline is retained and compared with the files retained by the current complete rendering. Unchanged and budget-omitted files append nothing; offline additions, edits, removals, and files leaving the retained budget set append `set`, `replace`, or `remove` transitions. An incompatible visible baseline is superseded by one complete current baseline, including an explicit empty baseline when no candidate remains. There is no file watcher, so an on-disk change becomes visible at the next successful `read`, `write`, or `edit` touch, when a resumed session reconciles its baseline, or when an entering pre-step restores a shadowed baseline.

-`maxBytes` is required so each deployment makes its prompt-budget choice explicitly. `maxSourceBytes` limits each source instruction file before rendering and defaults to 1 MiB. `projectRootMarkers` defaults to `['.git']`, and `instructionFileCandidates` defaults to `['AGENTS.md', 'CLAUDE.md']`. In each project directory every existing candidate loads, and candidates whose content matches an earlier one after trimming surrounding whitespace are dropped, so with the defaults an `AGENTS.md` and a `CLAUDE.md` that share content render once (as `AGENTS.md`) while genuinely distinct siblings both apply. `localInstructionFileCandidates` defaults to `['AGENTS.local.md', 'CLAUDE.local.md']` and loads its existing overlays alongside the base files of the same directory (rendered after them) under the same per-directory dedup; an empty list disables the overlay. Candidate entries in both lists must be same-directory file names, so empty entries, `.`/`..`, and entries containing `/` or `\` are ignored.

-The user-global file is always `$DSH_HOME/AGENTS.md` with no local overlay; both candidate lists only control project scopes. `$DSH_HOME` defaults to `~/.dsh`, and configured `~`, `~/...`, and Windows-style `~\...` prefixes are expanded against the operating-system home directory. A non-positive or non-finite render budget disables both baseline and dynamic loading; configured `maxSourceBytes` must be a positive integer.

-## Budgeting And Bounded Reads

+Rendering keeps the most specific files first: it drops whole broader files before truncating the most-specific file, and emits a visible `Workspace instruction budget ...` notice naming the omitted and truncated paths. The rendered bytes never exceed `maxBytes`. An over-budget broad file is ignored; during refresh it is treated as temporarily unavailable rather than removed.
 
-Instruction content is read through `streamText()` under `maxSourceBytes`, even when provider metadata omits size or a file grows after its metadata probe. An oversized file is ignored; during dynamic reconciliation it is temporarily unavailable rather than removed. The plugin keeps no process-wide cache and never caches instruction prose. Its session-local scope cache uses provider versions only as a fast invalidation signal; after invalidation, SHA-1 over the bounded read remains the cross-provider content identity stored in the structured message source.

+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the plugin; the observable behavior is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The plugin is built on one principle: workspace instructions are durable conversation content, owned per agent and per session. Baseline and refresh messages are ordinary sourced `user/message` events, so they replay, compact, and resume exactly like other history, and model-visible state is always reconstructable from the session log. The plugin owns the complete `<system-reminder>` framing and every injected message reaches the model verbatim.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: pre-step listener, `tools/result` touch tracking, inbox composition |
+| [`src/config.ts`](src/config.ts) | `Config` schema, budget resolution, baseline identity |
+| [`src/files.ts`](src/files.ts) | Candidate discovery, project-root search, bounded streaming reads |
+| [`src/render.ts`](src/render.ts) | Instruction rendering, budget truncation, change records |
+| [`src/state.ts`](src/state.ts) | Durable message sources, version/digest cache, reconciliation |
+| [`src/digest.ts`](src/digest.ts) | SHA-1 content identity and per-directory duplicate keys |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion for the durable context contract |
+
+### Main flow
+
+At the first eligible `agent/pre-step` of a session, the plugin composes the baseline and folds it into the entering batch right after the claimed messages. Successful first-party `read`, `write`, and `edit` calls contribute touches that bubble up through parent execution tokens; once the enclosing step is durable, a projection reconciles the visible session state against the inbox and queues additions, replacements, or removals. An unchanged path with an unchanged digest is never injected again. Discovery follows structured filesystem activity rather than shell navigation, because each local shell call starts a fresh process and parsing arbitrary shell syntax is not a reliable filesystem seam.
+
+### Invariants
+
+Every injected message carries a typed source with its change list; a complete baseline also carries an identity derived from normalized discovery, precedence, project-root, and budget configuration, and a matching durable message confirms a queued baseline. Model-visible text contains no hidden state markers, and literal `</system-reminder>` text anywhere in instruction content or model-visible metadata is escaped so repository-controlled text cannot close the plugin-owned frame.

+These limits define when instruction loading is a poor fit or needs operational awareness. They are current package constraints, not a task backlog.
+
 - **Discovery follows structured fs tools, not shell navigation** — a `bash` command that changes directories does not trigger nested instruction discovery because shell syntax and per-call shell state are not a reliable filesystem seam.
 - **Refresh is touch-driven** — there is no watcher; external edits become visible on the next successful first-party `read`, `write`, or `edit`, when resume reconciles a visible baseline, or when an entering pre-step restores a shadowed baseline.
 - **Candidate semantics stay intentionally small** — lowercase names, `.claude/rules/`, and `@path` imports are not interpreted; project scopes load `AGENTS.local.md`/`CLAUDE.local.md` overlays by default, but the user-global `$DSH_HOME` scope has no local overlay and other custom names require explicit candidate configuration.
 - **Per-directory dedup is content-based** — sibling candidates collapse only when byte-identical after trimming leading and trailing whitespace; a `CLAUDE.md` that symlinks its sibling `AGENTS.md` resolves to the same content and collapses like any duplicate, while a distinct real copy that has drifted from `AGENTS.md` loads in full alongside it.
 - **Symlinked instruction files are followed across the trust boundary** — a candidate whose final component is a symlink is resolved and its target loaded, so a cloned repository can surface off-tree file content as lower-authority workspace guidance (it never overrides system, developer, or direct user instructions). Confine `ctx.fs` with the filesystem policy gate or an OS sandbox when loading untrusted repositories.
 - **Instruction content is bounded, not summarized** — over-budget broad files are omitted and the most-specific file may be truncated; the plugin never asks a model to compress instruction prose.

-为每个会话加载与 `AGENTS.md` 兼容的工作区指令文件。该插件会将初始的用户全局指令与项目指令链注入持久历史，随后发现嵌套文件，并在成功的文件系统工具调用后报告后续变更或移除。
+## 概述
 
-## 生命周期
+`dsh-agent-instructions` 将兼容 `AGENTS.md` 的工作区指令文件加载到模型上下文：用户全局文件与项目指令链作为一条持久基线进入第一次请求，成功的 `read`、`write` 或 `edit` 调用会把新出现的嵌套文件、变更与移除带入后续请求。它随默认 `dsh-agent-spine-demo` 组合包发布并默认启用，可通过组合包配置禁用。一切内容都受字节预算约束：较宽泛的文件先被省略，最具体的文件最后被截断，空指令链不产生任何内容。没有文件 watcher——外部编辑会在下一次成功的文件系统 touch 时，或恢复后的会话对账其基线时变得可见。
 
-每个实时会话第一次符合条件的 `agent/pre-step` 会组合基线。当下游决策让非空的第一步批次进入时，插件会将基线折入最终批次、紧随已领取的直接提示词之后，使直接提示词与持久基线一同进入步骤 1，并共同抵达第一次请求。被拒绝或为空的第一步决策会将基线留在 agent（智能体）的 `next-step` inbox，等待后续唤醒。loader 先读取 `$DSH_HOME/AGENTS.md`，随后针对项目根目录到 `agent.session.header.cwd` 的每个目录，先读取每个现有基础候选文件，再读取每个现有本地 overlay 候选文件。同一目录中，如果候选文件在去除首尾空白后字节完全一致，就会按已配置顺序折叠到最早候选文件，因此 `CLAUDE.md` 若只是复制同级 `AGENTS.md`，只会渲染一次。若之前排队的 workspace 上下文仍在等待，插件会删除并替换该确切 inbox 条目，而不会不断累积副本。恢复后的会话会保留一条兼容的可见基线，并只追加当前文件的转换；如果发现、优先级、项目根目录或预算标识发生变化，则会将一条明确取代旧基线的完整基线折入进入步骤的批次。
+## 目录
 
-该插件还会观察第一方 `read`、`write` 和 `edit` 调用成功后产生的不可变 `tools/result`。每个已接受的 touch 都会检查新达到的后代 scope 以及之前加载的每个 scope。每个已配置候选名称都是所在目录中的独立 scope：新出现的文件会在 agent inbox 中排入一项新增；已改变文件会排入一项替换；文件消失或成为同一目录中较早候选文件的重复项时，会排入一则移除通知。原生调用与 Code Mode 子分派共享该路径：嵌套 touch 会沿不透明的父级执行 token 逐层上浮，直到顶层结果落定；在 agent loop（智能体循环）步骤内产生的 touch，须等持久 `step/end` 后才开始异步投影。打开的步骤之外直接执行工具时，则立即投影。这样无需依赖文件系统时序，也能保持工具调用／结果／步骤的相邻关系。这种发现跟随结构化文件系统活动，而不是 shell `cd`，因为每次本地 bash 调用都启动新 shell，解析任意 shell 语法也不可靠。

-指令读取使用可选 `ctx.fs` 提供方。该插件不会静态注入 `fs`，因此没有提供方的产品树仍可启动，指令加载在提供方出现前不执行任何操作。它会解析每个候选文件并对解析结果执行 stat，因此会跟随路径最后一段的 symlink 到其目标：指向常规文件的链接会加载目标内容，缺失路径或非文件目标（包括指向目录的链接）则已确认不存在。resolve 或 stat 异常会改为将该候选文件的 scope 标记为暂时不可用。前缀取消与动态工具取消会传播到解析、元数据探测与流式读取。文件加载后的提供方失败会视为暂时不可用，而非文件已删除的证据。

-
-该插件控制完整的 `<system-reminder>` 框架，每个注入的 `user/message` 都不经核心包装便原样传给模型。

-## 状态与刷新
-
-模型可见文本不含隐藏状态标记。每个基线或动态上下文事件改为携带带类型的 `agent-instructions` 来源，其中包含 `{ action, scope, path, digest? }` 变更列表；完整基线还会携带 `baseline: true`，以及从规范化的发现、优先级、项目根目录和预算配置派生的 `baselineIdentity`。匹配的持久 `user/message` 会确认已排队基线及其候选版本。进入步骤的 pre-step 会等待所有已排队投影完成，再把新组合的上下文折入最终批次，位置紧随已领取的消息，并移除 inbox 中仍待处理的副本；若被拒绝，当前上下文则继续排队。若监听器改写掉已领取的 workspace 消息，又没有让替代消息进入，后续边界会重新组合当前上下文。即使后续复合结果被拦截，成功的嵌套文件 touch 也会聚合到父级执行 token 下；顶层结果会将这些 touch 交给当前打开的会话步骤，或直接交给逐 agent 投影队列。`step/end` 只会在自身边界进入持久历史后释放其暂存的 touch；串行投影会根据可见会话事件和当前 inbox 协调状态，再替换唯一一条待处理工作区上下文。
-
-路径与 SHA-1 内容 digest 都未变时，不会重复注入。每会话、每 scope 提供方 cache 只存储 `{ path, version, digest, trimmedDigest }`：当提供方的不透明 `FsVersion` 与有效可见状态都匹配时，对账会跳过内容读取；版本改变会在任何模型可见更新之前触发有界读取与 SHA-1 确认。`trimmedDigest` 是针对去除空白后内容的 SHA-1，也是每目录重复 key，因此较早候选文件与某个未更改文件的内容收敛后，后者仍可被移除。恢复可行，因为 SHA-1 状态持久化在带类型的来源中，而空的内存版本 cache 只会导致一次确认读取。压缩（compaction）会在 scope 的上下文事件离开可见表层后重新启用它，即使缓存版本未变。移除是 tombstone，因此候选文件之后重新出现时会重新加载。模型可见变更只有在对应文件专属段落保留至少一个内容字节，或原始内容确实为空时，才会进入来源、pending 状态和版本 cache。只要任一内容字节保留下来，部分截断就会记录完整内容的 digest；截断到零字节则仍可在后续 touch 处理，而相同 digest 的版本刷新只更新提供方 cache。基线即使带空变更列表，仍可发布字节预算诊断。动态批次若没有可提交变更，则完全不注入，并在后续 touch 时重试。
-
-初始基线事件自身不会被改写。其带类型的变更仅在该事件仍位于可见会话表层时才是权威状态。当压缩遮蔽该事件时，下一次进入步骤的 pre-step 会组合当前基线，并在同一请求中记录它；也可以改由一次成功的文件系统 touch 重新添加未变的基线 scope，或追加其替换或移除。内存中的 scope 标记和提供方版本 cache 只负责选择探测对象并加速探测。恢复或插件热重挂后的第一次 pre-step 会保留兼容的可见基线，并将它与当前完整渲染所保留的文件进行比较。未变化和被预算省略的文件不追加任何内容；agent 离线期间新增、编辑、移除或不再属于预算保留集的文件会追加 `set`、`replace` 或 `remove` 转换。不兼容的可见基线会被一条完整的当前基线取代；如果没有候选文件，这条当前基线会是显式空基线。没有文件 watcher，因此磁盘变更会在下一次成功 `read`、`write` 或 `edit` touch 时可见，也会在恢复后的会话对账其基线时，或进入步骤的 pre-step 恢复被遮蔽的基线时可见。

-Local-filesystem implementation of `ctx.fileReferences`. It maintains one bounded `WorkspaceFileSearch` per agent, rooted at that session's `cwd` and falling back to the host process cwd. The index ranks direct directory listings for queries containing `/`, otherwise fuzzy-ranks a bounded recursive index; it never follows directory symlinks.
+## Summary
 
-Tool-result events invalidate the addressed agent's reusable index so later completion observes likely workspace mutations. Agent disposal releases that index and its scoped prompt contribution; plugin disposal awaits every prompt fiber and releases all cached searches.
+Agents and their host UIs get ranked path candidates for `@file` mentions, scoped to each agent's workspace and bounded so even large repositories stay responsive. `dsh-file-reference-local` implements `ctx.fileReferences` for the local filesystem: it keeps one reusable search index per agent, invalidates it after tool results so completion reflects workspace changes, and never follows directory symlinks. When the addressed agent can call `read`, it also installs a stable one-sentence guidance into the system prompt. Choose it when the agent's `read` tool operates on the Harness host filesystem; remote or virtual namespaces need a provider whose discovery matches the tool.

+## Use this package
+
+Mount this provider when `@file` completion should discover the Harness host's own filesystem — the namespace the shipped `read` tool operates on. Each agent's workspace is indexed from its session working directory, falling back to the host process directory when the session has none.
+
+### Enabling the provider
+
+The defaults suit a typical workspace, so the minimal mount needs no configuration:
+
+```yaml
+- name: '@deepseek-ai/dsh-file-reference-local'
+  config:
+    maxResults: 20
+```
+
+### What you get
+
+Typing `@` in a host UI returns up to `maxResults` ranked path candidates for the addressed agent. A query containing `/` lists the matching directory's entries directly; a bare query fuzzy-ranks the bounded recursive index. Directory candidates keep the mention open with a trailing slash. After any tool result, the agent's reusable index is invalidated, so later completion observes workspace mutations; an unchanged agent keeps its index across queries.
+
+### Configuration
+
+| Field | Default | Meaning |
+|---|---|---|
+| `maxResults` | `20` | Maximum ranked candidates returned for one query |
+| `maxEntries` | `10000` | Maximum files and directories indexed per agent workspace |
+| `excludedDirectories` | `['.git', 'node_modules']` | Directory basenames omitted from traversal and candidates |
+
+Every numeric value must be a positive safe integer, and every excluded name must be a non-empty basename without `/` or `\`.

+## Understand the implementation

+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design of the provider; the observable behavior is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The provider maintains one reusable `WorkspaceFileSearch` per agent, rooted at that session's `cwd`. Directory-scoped queries (`a/b/...`) list live directory state, while bare fuzzy queries share one bounded recursive traversal until the `@` interaction ends or a `tool/result` event invalidates it. The model guidance is a per-agent prompt section contributed only while the addressed agent has a `read` tool; agent disposal releases both the index and the prompt fiber.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | `LocalFileReferenceService`: config validation, per-agent searches, prompt install |
+| [`src/search.ts`](src/search.ts) | `WorkspaceFileSearch`: traversal, ranking, exclusion, invalidation |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion for the discovery contract |
+
+### Main flow
+
+A `list(agent, query, signal)` call either lists one directory's entries or waits on the shared bounded index, ranks the candidates (exact, prefix, substring, then subsequence scores with directory bonuses), and returns at most `maxResults` in deterministic order. `tool/result` events invalidate the addressed agent's index so the next bare query observes a fresh tree; unreadable or excluded subtrees contribute no candidates.

+These limits define when the provider is a poor fit. They are current package constraints.

 - **Host-local namespace** — the provider scans the Harness host filesystem, so remote or virtual `read` implementations require a provider whose namespace matches the tool.
 - **Bounded advisory index** — very large workspaces may omit paths after `maxEntries`, and excluded or unreadable directories do not appear.
 - **No ignore-file semantics** — `.gitignore` and other project ignore files do not influence discovery; only configured directory basenames are excluded.

-File-reference discovery seam and browser-safe `@file` grammar shared by host-backed user interfaces. `ctx.fileReferences.list(agent, query, signal)` returns path-only file or directory candidates for the addressed agent; concrete providers own namespace access, ranking, caching, and invalidation. The same contract is remotely callable as the unary `fileReferences/list` Remote method (`@Remote` on the Service Definition, cancelled through the reserved trailing signal), so browser consumers call `ctx.remote.fileReferences.list` without an API Proxy route.
+## Summary
 
-`activeAtToken()` recognizes an `@path` or open `@"path with spaces` token only at the start of input or after whitespace, so email-like text does not open completion. `formatFileMention()` emits the matching prompt spelling, appends `/` to directory candidates, preserves an explicitly opened quote, and rejects control characters or embedded quotes that the editor grammar cannot represent safely.
+Host-backed user interfaces use `dsh-file-reference` to offer `@file` completion: a UI asks for path candidates for the addressed agent, the model types `@path` or `@"path with spaces"`, and picking a candidate inserts the matching mention as ordinary prompt text. The seam itself owns no filesystem access — a concrete provider such as `@deepseek-ai/dsh-file-reference-local` supplies candidates, ranking, caching, and invalidation. Selecting a candidate never reads or attaches file contents; the model must call a filesystem tool to inspect a file. The same discovery is callable from browser consumers through the remote `fileReferences/list` method without an API Proxy route.
 
-Selecting a candidate does not read or attach file contents. The exported `FILE_REFERENCE_PROMPT` is stable guidance that a provider may install when the addressed agent can call `read`.

+
+Choose this package when a host-backed UI (web or terminal) should offer `@file` completion, and pair it with a provider whose namespace matches the agent's effective `read` tool. Mounting the seam without a provider gives the UI an empty completion surface.
+
+### Mention grammar
+
+An `@path` token at the start of input or after whitespace triggers completion; an `@` inside another token, such as an email address, does not. `@"path with spaces"` opens a quoted mention, and a directory candidate keeps that quote open after its trailing slash so completion can descend another level. The formatter rejects paths with control characters or embedded quotes that the grammar cannot represent safely.

+`ctx.fileReferences.list(agent, query, signal)` returns path-only file and directory candidates for one agent's working directory, deterministically ranked by the provider. Directory mentions render with a trailing `/` so completion can descend another level. Browser consumers call the same discovery as `ctx.remote.fileReferences.list`; the reserved trailing signal cancels a slow autocomplete.
+
+### Pairing with a provider
+
+For a local filesystem, mount `@deepseek-ai/dsh-file-reference-local`; other namespaces (remote or virtual filesystems) need a provider whose discovery matches the effective tool. When the addressed agent can call `read`, a provider may install the stable `FILE_REFERENCE_PROMPT` guidance that tells the model to read a referenced file before claiming to have inspected it.

+
+This section explains the design of the seam; the observable behavior is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The package is one separation: an abstract discovery service plus a shared, browser-safe mention grammar, with providers owning namespace access, ranking, caching, and invalidation. The service is a `TypertRemoteService` whose `list` contract is remotely callable as the unary `fileReferences/list` method, so the same seam serves in-process and browser consumers.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Abstract `FileReferenceService`, `FILE_REFERENCE_PROMPT`, remote `list` face |
+| [`src/grammar.ts`](src/grammar.ts) | `activeAtToken` recognition and `formatFileMention` rendering |
+| [`src/types.ts`](src/types.ts) | `FileReferenceCandidate` path-only result type |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion for the discovery contract |
+
+### Main flow
+
+The UI recognizes an active `@` token through `activeAtToken`, calls `list` with the query text, and renders the ranked candidates. On selection, `formatFileMention` emits the matching prompt spelling (`@path`, `@"path with spaces"`, or an open `@"dir/` for a quoted directory). No file content is read at any point; providers may additionally install the stable `FILE_REFERENCE_PROMPT` section when the addressed agent has a `read` tool.

 ## Model Experience
 
-Indirectly, through `@deepseek-ai/dsh-file-reference-local`, which conditionally contributes this package's stable file-reference guidance.
+Indirectly, through the composed provider, which owns the file-reference guidance that this package's discovery seam and grammar delegate to it.
 
 #### KV Cache effect
 
-The interface and grammar add no request tokens themselves; a provider-owned prompt section determines cache behavior.
+The interface and grammar add no request tokens; a provider-owned prompt section determines whether the reusable prefix changes.
 
 ## Known Limitations and Deferred Work
 
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define when the seam is a poor fit. They are current package constraints.
+
 - **Path candidates are advisory** — the seam does not prove that a later model-facing filesystem tool can access the same namespace; deployments must align the provider with the effective `read` implementation.
 - **No file-content reference object** — selected files remain ordinary prompt text and require an explicit model tool call before their contents become model-visible.

-文件引用发现 seam，以及供宿主驱动的用户界面共享、可在浏览器中安全使用的 `@file` 语法。`ctx.fileReferences.list(agent, query, signal)` 为指定 agent（智能体）返回仅含路径的文件或目录候选；具体提供方负责命名空间访问、排序、缓存和失效处理。同一契约以一元 `fileReferences/list` Remote 方法对外可调（`@Remote` 标注在 Service Definition 上，经保留的末位 signal 参数取消），浏览器消费方直接调用 `ctx.remote.fileReferences.list`，无需 API Proxy 路由。

-`activeAtToken()` 只在输入开头或空白后识别 `@path` 或尚未闭合的 `@"path with spaces` token，因此类似电子邮件的文本不会打开补全。`formatFileMention()` 会生成与提示词匹配的写法，为目录候选追加 `/`，保留显式打开的引号，并拒绝编辑器语法无法安全表示的控制字符或内嵌引号。
+宿主驱动 UI 使用 `dsh-file-reference` 提供 `@file` 补全：UI 为指定 agent 请求路径候选，模型输入 `@path` 或 `@"path with spaces"`，选中候选后，匹配的 mention 作为普通提示词文本插入。seam 本身不拥有文件系统访问——具体提供方（如 `@deepseek-ai/dsh-file-reference-local`）负责提供候选、排序、缓存与失效。选中候选绝不读取或附带文件内容；模型必须调用文件系统工具才能查看文件。浏览器消费方无需 API Proxy 路由，即可通过远程 `fileReferences/list` 方法调用同一发现能力。

+
+本包建立在一个分离上：抽象发现服务加共享、浏览器安全的 mention 语法，由提供方负责命名空间访问、排序、缓存与失效。该服务是 `TypertRemoteService`，其 `list` 约定可通过一元 `fileReferences/list` 方法远程调用，因此同一 seam 同时服务进程内与浏览器消费方。

-`ctx.sessionReferenceResolver` prepares bounded, read-only snapshots of other sessions as sourced model-facing context. It consumes `ctx.sessionQuery` and the backend-independent compact checkpoint marker; SQLite FTS is not required. Hosts that support cross-session mentions may opt into the service.
+## Summary
 
-## Public API
+`dsh-session-reference` lets a conversation reference other sessions: a host turns a `@label` mention into a canonical URI, and the service prepares a bounded, read-only snapshot of each referenced session as durable, untrusted background context for the model. Candidate discovery ranks other sessions by working-directory affinity and labels them with their latest titles. Snapshots are immutable after capture and carry a fixed warning that forbids following instructions, permission claims, or tool requests inside them. It is an opt-in service for hosts that support cross-session mentions; it consumes `ctx.sessionQuery` and needs no SQLite FTS.
 
-- `listCandidates(agent, query?, limit?)` lists sessions other than `agent.id`, filters case-insensitively by id, cwd, or the latest log-backed title, and ranks same-cwd, cwd-less, then other-cwd records while preserving `listSessions()` creation order within each group. Each selected candidate uses that title as the mention label and falls back to the session id when the title is absent or unreadable; message bodies are not searched. The unary `sessionReferenceResolver/candidates` Remote method serves the same discovery under the configured candidate limit and attaches each candidate's canonical mention, so browser consumers call `ctx.remote.sessionReferenceResolver.candidates` without an API Proxy route.
-- `prepare(agent, content, references, signal?)` preserves first-mention order, deduplicates ids, rejects self-reference and more than the configured distinct-source limit, reads every source in parallel, and returns detached content plus zero or one aggregated, identified `UserMessage` context. The service calls it for canonical mentions in direct user messages after downstream `agent/pre-step` listeners accept the step.
-- `encodeSessionReferenceUri()` and `decodeSessionReferenceUri()` implement `dsh-session:<base64url(JSON.stringify(sessionId))>` so every JavaScript string id round-trips exactly. `formatSessionReferenceMention()` emits `@[label](uri)`, and `parseSessionReferenceText()` replaces Markdown mentions or bare canonical URIs with readable `@label` text while returning structured references. Explicit Markdown mentions reject every malformed URI; bare text is considered a reference only when a non-empty base64url-shaped payload follows the scheme, and a matching noncanonical candidate still fails. Empty or punctuation-only scheme mentions remain ordinary discussion text.

-Preparation calls `ctx.sessionQuery.readSurface()` once per distinct source when the target message reaches `agent/pre-step`. A queued message therefore captures the source state at model-step entry, and the resulting context is immutable after that point. Projection keeps only direct-user `user/message`, assistant text, and `user/message` checkpoints carrying the canonical `dsh-compaction` source marker from the folded current surface. Separately sourced session-reference messages are injected context and are excluded, preventing recursive snapshot propagation. Shadowed pre-compaction events, tools, reasoning, other plugin-generated user messages except marked compact checkpoints, and unfinished assistant chunks are also excluded. A compacted source therefore contributes its latest checkpoint plus retained later conversation, not restored shadowed text.
+-----
 
-The context source is `{ kind: 'session-reference', version: 1, references }`; each reference records its source id and label, capture seq, compact presence, retained/omitted message counts, omitted UTF-8 bytes, and truncation state. The service's outer `agent/pre-step` listener post-processes accepted direct user messages, preserves their message ids, and inserts each snapshot immediately after the message that cited it. Queue edits and queue-to-steer relocation need no reference-specific handling because parsing occurs after the final inbox claim. Invalid mentions, failed reads, cancellation, and budget failures end that turn before its messages enter model-visible history. The target log records the readable direct `user/message` followed by its sourced context `user/message`; source mutation after capture cannot change target replay.
+<a id="use-this-package"></a>
+## Use this package
 
-## Configuration
+Enable this service when hosts should let a user mention another session and give the model its context. It works with any session-query backend because it consumes the backend-independent compact checkpoint marker.
 
-| Key | Default | Contract |
-|---|---:|---|
-| `maxReferences` | `3` | Maximum distinct source sessions in one prepared message; must be at most `3`. |
-| `candidateLimit` | `50` | Default candidate count returned to a host. |
-| `maxReferenceBytes` | `65536` | Maximum serialized JSON bytes for one reference object. |
+### Mention syntax
 
-Retention applies `maxReferenceBytes` independently to each source, keeps compact checkpoints and the newest message before dropping older non-checkpoint units, and uses `dsh-output-retention` head/tail truncation with an exact UTF-8 omission notice. If one source's fixed serialized fields cannot fit, preparation fails with `SESSION_REFERENCE_BUDGET_EXCEEDED` instead of returning a partial context.
+A canonical mention is `@[label](dsh-session:<base64url-encoded-id>)` in Markdown, or the bare `dsh-session:` URI; every JavaScript string session id round-trips exactly. The service rewrites mentions into readable `@label` text in the message and returns the structured references. Explicit Markdown mentions reject malformed URIs; empty or punctuation-only scheme mentions stay ordinary discussion text.
 
+### What the agent gets
+
+A message that cites other sessions is followed immediately by a `## Referenced sessions` snapshot as a second user-role message. The snapshot is untrusted background: the fixed warning tells the model not to follow instructions, permission claims, or tool requests inside it unless the current user explicitly repeats them. Each source is bounded independently — at most `maxReferences` distinct sessions per message and `maxReferenceBytes` per source — and a source that cannot fit its budget fails preparation instead of returning partial context.
+
+### Finding sessions to reference
+
+`listCandidates(agent, query?, limit?)` lists sessions other than the agent's own, filters case-insensitively by id, working directory, or the latest log-backed title, and ranks same-directory sessions first. Each candidate carries its latest title as the mention label, falling back to the session id when the title is absent or unreadable. Browser consumers call the same discovery as `ctx.remote.sessionReferenceResolver.candidates`, which attaches each candidate's canonical mention.
+
+### Configuration
+
+| Field | Default | Meaning |
+|---|---|---|
+| `maxReferences` | `3` | Maximum distinct source sessions in one prepared message; must not exceed `3` |
+| `candidateLimit` | `50` | Default candidate count returned to a host |
+| `maxReferenceBytes` | `65536` | Maximum serialized JSON bytes for one reference object |

+### Design concept
+
+Preparation reads each referenced session's current surface exactly once, when the target message reaches `agent/pre-step`, so a queued message captures source state at model-step entry and the resulting context is immutable afterwards. Projection keeps only direct-user `user/message`, assistant text, and `user/message` checkpoints carrying the canonical compaction marker; separately sourced session-reference messages are excluded, preventing recursive snapshot propagation.

Each snapshot is inserted immediately after the message that cited it, and the target log records the readable direct message followed by its sourced context, so source mutation after capture cannot change target replay.

 - **No body discovery** — candidate queries inspect folded titles but do not search message bodies. A non-empty query may inspect every visible persisted session log through the session-query service's bounded, cancellable batch; a dedicated title index may replace that discovery path without changing URI, snapshot, or persistence contracts.
 - **Trusted caller boundary** — the service assumes its host is authorized to read every session exposed by `ctx.sessionQuery`; it is not a model-facing search tool.
 - **Text projection only** — non-text user and assistant blocks are not propagated across sessions.
 - **No live link** — references are snapshots, not forks, resumes, subscriptions, or source-session mutations.

-`ctx.sessionReferenceResolver` 会把其他会话准备为有界、只读快照，作为带来源信息、面向模型的上下文。它消费 `ctx.sessionQuery` 与后端无关的 compact 检查点标记；不需要 SQLite FTS。支持跨会话 mention 的宿主可以主动启用该服务。
+## 概述
 
-## 公开 API
+`dsh-session-reference` 让一次对话可以引用其他会话：宿主把 `@label` mention 转换为规范 URI，服务则为模型准备每个被引用会话的有界、只读快照，作为持久、不受信任的背景上下文。候选发现按工作目录亲和度对其他会话排序，并用其最新标题作标签。快照在捕获后不可变，并带有固定警告，禁止遵循其中的指令、权限声明或工具请求。它是面向支持跨会话 mention 的宿主的可选服务；它消费 `ctx.sessionQuery`，不需要 SQLite FTS。
 
-- `listCandidates(agent, query?, limit?)` 会列出 `agent.id` 之外的会话，按 id、cwd 或以日志为依据的最新标题进行不区分大小写的筛选，再按同 cwd、无 cwd、其他 cwd 记录排序，同时保持每组内的 `listSessions()` 创建顺序。每个已选候选会话都使用该标题作为 mention label；标题不存在或无法读取时回退到会话 id。不搜索消息主体。一元 `sessionReferenceResolver/candidates` Remote 方法在配置的候选上限内提供同一发现能力，并为每个候选附上规范 mention，浏览器消费方直接调用 `ctx.remote.sessionReferenceResolver.candidates`，无需 API Proxy 路由。
-- `prepare(agent, content, references, signal?)` 会保留首次 mention 顺序、对 id 去重，并拒绝自引用或超过已配置不同源上限的情况。它会并行读取所有源，返回与输入脱离的内容，外加零个或一个聚合且带标识的 `UserMessage` 上下文。下游 `agent/pre-step` 监听器接受步骤后，该服务会针对直接用户消息中的规范 mention 调用此方法。
-- `encodeSessionReferenceUri()` 与 `decodeSessionReferenceUri()` 实现 `dsh-session:<base64url(JSON.stringify(sessionId))>`，因此每个 JavaScript 字符串 id 都能精确往返。`formatSessionReferenceMention()` 发出 `@[label](uri)`，`parseSessionReferenceText()` 将 Markdown mention 或裸规范 URI 替换为可读的 `@label` 文本，并返回结构化引用。解析器会拒绝显式 Markdown mention 中任何格式错误的 URI；只当 scheme 后跟非空、符合 base64url 形状的 payload 时，裸文本才被视为引用，匹配但非规范的候选项仍会失败。空 scheme mention 或只含标点符号的 scheme mention 仍是普通讨论文本。

-目标消息到达 `agent/pre-step` 时，准备阶段会对每个不同源调用一次 `ctx.sessionQuery.readSurface()`。因此，queued 消息在进入模型步骤时捕获源状态，此后生成的上下文保持不变。它仅投影折叠后当前表层中的用户直接发出的 `user/message`、assistant 文本，以及 `user/message` 检查点；这类检查点携带规范 `dsh-compaction` 源标记。带独立来源的 session-reference 消息属于注入上下文，会被排除以防止快照递归传播。已遮蔽的压缩（compaction）前事件、工具、推理（reasoning）、除已标记 compact 检查点外的其他插件生成 user 消息，以及未完成的 assistant 分片也都会被排除。因此，已压缩源只会提供最新检查点及其后保留的会话内容，不会还原已遮蔽的文本。

-上下文源为 `{ kind: 'session-reference', version: 1, references }`；每条引用会记录其源 id 与 label、捕获 seq、是否存在 compact、已保留／已省略消息数、已省略 UTF-8 字节数与截断状态。该服务的外层 `agent/pre-step` 监听器会处理已接受的直接用户消息，保留其消息 id，并把每份快照插入到引用它的消息紧后。解析发生在最终领取收件箱消息之后，因此队列编辑和从 queue 移动到 steer 不需要引用专用处理。无效 mention、读取失败、取消和预算失败会在消息进入面向模型的历史之前结束该轮次。目标日志会先记录可读的直接 `user/message`，再记录其带来源信息的上下文 `user/message`；捕获后的源变更无法改变目标回放。

-Opt-in durable context with the current zoned time, the browser zone attached to the open request, and elapsed time sampled during model-request preparation. Default compositions leave it disabled; the Schedule Web overlay mounts it so the model can interpret otherwise-unqualified dates and times in the user's browser zone. Decision record: [the durable time-context Agent Note](../../../.agents/notes/implemented/feature/2026-07-16-durable-per-step-time-context.md).
+## Summary
 
-## Config
+`dsh-time-context` gives the model a clock: on eligible steps it appends a durable, source-attributed reading with the current time, the browser zone attached to the open request, and the elapsed time since the preceding model-visible message. It helps the model interpret otherwise-unqualified dates and times in the user's browser zone, and tells it to ask when zone provenance is mixed or missing. The plugin is opt-in: default compositions leave it disabled, and the Schedule Web overlay mounts it. A positive `refreshIntervalMs` reduces how often readings accumulate; omission or `0` injects at every eligible step.

+<a id="use-this-package"></a>
+## Use this package
+
+Mount this plugin when the model should interpret unqualified dates and times in the user's zone, and when a request-local browser zone is available or a configured fallback is acceptable. Each injection is one additional user-role message in the durable history; schedule it with `refreshIntervalMs` when per-step readings are more than the conversation needs.
+
+### What the agent gets
+
+Each injected reading has three lines: an ISO-shaped timestamp with numeric offset and IANA zone, the browser-zone policy for the request, and the elapsed duration in compact whole-second units. Step 1 measures from the latest preceding model-visible message; later steps measure from the preceding time-context event in the same turn. A missing baseline reports `unavailable`, and backward wall-clock movement clamps elapsed time to zero.
+
+### Configuration
+
+The minimal mount needs no configuration. A positive `refreshIntervalMs` suppresses injections that fall within that many milliseconds of the latest one; omission or `0` injects at every eligible entering pre-step whose signal is not already aborted.
 
 ```yaml
-- id: time-context
-  name: '@deepseek-ai/dsh-time-context'
+- name: '@deepseek-ai/dsh-time-context'
   config:
-    timeZone: Asia/Shanghai  # optional fallback when the request has no unique browser zone
-    refreshIntervalMs: 60000 # optional; omit or set to 0 for every eligible attempt
+    timeZone: Asia/Shanghai
 ```
 
-When the open turn contains one Host-validated browser zone, that request-local zone formats the timestamp. With missing or mixed browser provenance, `timeZone` supplies the display fallback; omitting it resolves the Node process zone once at plugin load. Node honors `TZ`, and every explicit fallback is validated through `Intl.DateTimeFormat`.
+| Field | Default | Meaning |
+|---|---|---|
+| `timeZone` | process zone | Fallback display zone when the open turn has no unique browser zone |
+| `refreshIntervalMs` | `0` (every eligible step) | Minimum milliseconds between durable injections in one session |
 
-`refreshIntervalMs` must be a non-negative safe integer. Omission or `0` adds context to every eligible entering pre-step whose signal is not already aborted. A positive value adds it only when the Session has no earlier time-context injection, wall time moved backward, or at least that many milliseconds elapsed since the latest injection.
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-time-context) is the exhaustive source for every accepted field and its JSDoc.
 
-## Request-zone ownership
+### Choosing the zone
 
-The browser samples `Intl.DateTimeFormat().resolvedOptions().timeZone` for each prompt. The Host validates and canonicalizes that value before binding it to the exact durable `user-rpc` message source. Time-context examines only those sources in the open turn: one unique zone resolves the request, multiple zones are `mixed`, and none are `unavailable`. It does not read or mutate Session headers, connection state, or Schedule records.
+When the open turn contains exactly one Host-validated browser zone, the timestamp is formatted in that request-local zone. With missing or mixed browser provenance, the configured `timeZone` formats the display; omitting it resolves the Node process zone once at plugin load, and every explicit fallback is validated through `Intl.DateTimeFormat`. The resolved instruction tells the model to interpret unqualified dates and times in the chosen zone, and to ask the user to clarify when provenance is mixed or unavailable.
 
-The resolved instruction tells the model to interpret otherwise-unqualified dates and times in that browser zone. Mixed or unavailable provenance tells the model to ask the user to clarify. This is natural-language context, not an input default at another package boundary: a tool that accepts local calendar fields still owns its explicit zone requirement.
+-----
 
-## Timing semantics
+<a id="understand-the-implementation"></a>
+## Understand the implementation
 
-The plugin prepends an `agent/pre-step` listener and delegates first. When an injection is due and the downstream decision enters, it appends one sourced `UserMessage` to the returned batch. AgentLoop records the final batch after `step/start` and before request derivation. Rejection, listener failure, or an already-aborted signal records nothing.
+<details>
+<summary>Implementation internals — click to expand</summary>
 
-Each reading uses the exact snapshot source `{ kind: 'plugin', plugin: 'time-context', form: 'snapshot', sections: [{ name: 'time-context', text: <same text> }] }`. The `./invariant` companion validates that shape, re-derives the current-turn browser policy from the original `user-rpc` messages, and checks the timestamp zone and elapsed baseline.
+This section explains the design of the plugin; the observable behavior is covered in [Use this package](#use-this-package).
 
-Positive-interval scheduling scans raw durable Session events for the latest plugin-attributed message, including a reading shadowed by compaction. It therefore survives resume without a process-local cache. A positive interval can intentionally let a later request reuse existing history without a fresh reading; the Schedule Web overlay omits the interval.
+### Design concept
 
-Step 1 measures from the latest preceding durable user, assistant, or tool-result message. The prompt proposed for that step has not been appended yet. Later steps measure from the preceding time-context event in the same turn. Missing baselines report `unavailable`, and backward wall-clock movement clamps elapsed time to zero.
+The plugin prepends an `agent/pre-step` listener that delegates first and appends one sourced `UserMessage` when an injection is due and the downstream decision enters the step. Each reading uses the exact snapshot source `{ kind: 'plugin', plugin: 'time-context', form: 'snapshot', sections: [{ name: 'time-context', text }] }`, and the invariant companion validates that shape, re-derives the current-turn browser policy from the original `user-rpc` messages, and checks the timestamp zone and elapsed baseline.
 
-A reading records an entered step, not a completed or transmitted request. A later preparation failure can leave it in history. The message remains in derived conversation history until compaction shadows it; `request/header` contains no time-context state, and request reconstruction uses the complete durable surface prefix after each `step/start`.
+### Source map
 
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: pre-step listener, due scheduling, reading composition |
+| [`src/request-zone.ts`](src/request-zone.ts) | Browser-zone policy derivation from open-turn `user-rpc` sources |
+| [`src/timestamp.ts`](src/timestamp.ts) | `Intl.DateTimeFormat` creation and timestamp formatting |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion for the snapshot contract |
+
+### Main flow
+
+When an injection is due, the plugin samples the wall clock, derives the browser-zone policy from the open turn's `user-rpc` messages, resolves the display zone (request-local or fallback), and renders the three-line reading. Positive-interval scheduling scans raw durable session events for the latest plugin-attributed message — including one shadowed by compaction — so the schedule survives resume without a process-local cache. A reading records an entered step, not a completed or transmitted request; a later preparation failure can leave it in history.

+These limits define when clock context is a poor fit. They are current package constraints.
+
 - **Prompt provenance only** — browser-zone context guides natural-language interpretation but does not silently supply another tool's required zone field.
 - **Mixed turns ask** — if one open turn contains prompts from different browser zones, the model is told to clarify rather than guess which one owns an unqualified time.
 - **Fallback is not user authority** — the configured or process zone formats the clock when browser provenance is missing or mixed, but the model-facing policy still says to clarify.
 - **Whole-second display** — timestamps and durations omit sub-second precision even though durable event times retain milliseconds.
 - **History cost between compactions** — omission or `0` retains one reading for every eligible attempt; a positive interval reduces but does not eliminate this cost and may leave a later request without fresh browser-zone guidance.

+## 使用本包
+
+当模型需要按用户所在时区解释未限定的日期与时间，且请求本地浏览器时区可用或已配置的回退值可接受时，挂载此插件。每次注入都是持久历史中额外的一条 user 角色消息；当按步骤读数超出对话需要时，用 `refreshIntervalMs` 调度。
+
+### 模型能得到什么
+
+每条注入读数包含三行：带数字偏移与 IANA 时区、形如 ISO 的时间戳，该请求的浏览器时区策略，以及以紧凑整秒单位表示的经过时长。第 1 步从最新一条先前模型可见消息起测量；后续步骤从同一轮次中前一个 time-context 事件起测量。缺少基线时报告 `unavailable`，挂钟时间倒退时把经过时长钳制为零。
+
+### 配置
+
+最小挂载无需任何配置。正的 `refreshIntervalMs` 会抑制距最近一次注入不足该毫秒数的注入；省略或设为 `0` 时，每个信号尚未中止且将进入步骤的合格 pre-step 都会注入。
 
 ```yaml
-- id: time-context
-  name: '@deepseek-ai/dsh-time-context'
+- name: '@deepseek-ai/dsh-time-context'
   config:
-    timeZone: Asia/Shanghai  # optional fallback when the request has no unique browser zone
-    refreshIntervalMs: 60000 # optional; omit or set to 0 for every eligible attempt
+    timeZone: Asia/Shanghai
 ```
 
-当当前开放轮次只包含一个经 Host 校验的浏览器时区时，使用该请求本地时区格式化时间戳。浏览器来源信息缺失或混杂时，`timeZone` 提供显示回退；省略它则会在插件加载时解析一次 Node 进程时区。Node 遵循 `TZ`，每个显式回退值都经 `Intl.DateTimeFormat` 校验。
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `timeZone` | 进程时区 | 当前开放轮次没有唯一浏览器时区时的显示回退时区 |
+| `refreshIntervalMs` | `0`（每个合格步骤） | 同一会话中两次持久注入之间的最小毫秒数 |
 
-`refreshIntervalMs` 必须是非负安全整数。省略或设为 `0` 时，会为每个信号尚未中止且将进入步骤的合格 pre-step 添加上下文。正数值只会在会话没有更早的 time-context 注入、挂钟时间倒退，或自最新注入起已经过至少相应毫秒数时添加上下文。
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-time-context)是每个受支持字段及其 JSDoc 的穷尽式真源。
 
-## 请求时区归属
+### 选择时区
 
-浏览器会为每条提示词采样 `Intl.DateTimeFormat().resolvedOptions().timeZone`。Host 校验并规范化该值，再将其绑定到确切的持久 `user-rpc` 消息来源。Time-context 只检查当前开放轮次中的这些来源：唯一一个时区可解析请求，多个时区记为 `mixed`，没有时区则记为 `unavailable`。它不会读取或修改会话标头、连接状态或 Schedule 记录。
+当当前开放轮次只包含一个经 Host 校验的浏览器时区时，时间戳按该请求本地时区格式化。浏览器来源信息缺失或混杂时，配置的 `timeZone` 格式化显示；省略它则在插件加载时解析一次 Node 进程时区，每个显式回退值都经 `Intl.DateTimeFormat` 校验。解析后的指令告诉模型按所选时区解释未限定的日期与时间；来源信息混杂或不可用时，则要求用户澄清。
 
-解析后的指令告诉模型，把未明确限定时区的日期和时间解释为该浏览器时区。来源信息为 mixed 或 unavailable 时，模型会收到要求用户澄清的指令。这是自然语言上下文，并非另一个包边界上的输入默认值：接受本地日历字段的工具仍自行负责其显式时区要求。

-## 时序语义
+<a id="understand-the-implementation"></a>
+## 理解实现
 
-该插件会前置一个 `agent/pre-step` 监听器，并先行委托下游。需要注入且下游决策进入步骤时，它会向返回批次追加一条带来源的 `UserMessage`。AgentLoop 在 `step/start` 之后、请求派生之前记录最终批次。决策被拒绝、监听器失败或信号已经中止时，不会记录任何内容。
+<details>
+<summary>实现细节——点击展开</summary>
 
-每个读数都使用确切的快照来源 `{ kind: 'plugin', plugin: 'time-context', form: 'snapshot', sections: [{ name: 'time-context', text: <same text> }] }`。`./invariant` 配套模块会校验该形状，根据原始 `user-rpc` 消息重新派生当前轮次的浏览器策略，并检查时间戳时区与经过时长基线。
+本节解释插件的设计；可观察行为见[使用本包](#use-this-package)。
 
-正数间隔调度会扫描原始持久会话事件，查找最新一条归因于插件的消息，其中包括已被压缩（compaction）遮蔽的读数。因此，它无需进程本地缓存也能在恢复后继续生效。正数间隔可以有意让后续请求复用现有历史，而不添加新读数；Schedule Web overlay 会省略该间隔。
+### 设计理念
 
-第 1 步从最新一条在其之前持久化的用户、助手或工具结果消息起测量。为该步骤拟议的提示词尚未追加。后续步骤从同一轮次中前一个 time-context 事件起测量。缺少基线时报告 `unavailable`，挂钟时间倒退时将经过时长限制为零。
+插件前置注册一个 `agent/pre-step` 监听器，先委托下游，需要注入且下游决策进入步骤时追加一条带来源的 `UserMessage`。每个读数都使用确切的快照来源 `{ kind: 'plugin', plugin: 'time-context', form: 'snapshot', sections: [{ name: 'time-context', text }] }`，不变式伴生插件会校验该形状，根据原始 `user-rpc` 消息重新派生当前轮次的浏览器策略，并检查时间戳时区与经过时长基线。
 
-读数记录的是已进入的步骤，不是已完成或已传输的请求。后续准备失败时，该读数可能留在历史中。消息会保留在派生会话历史中，直到压缩将其遮蔽；`request/header` 不含 time-context 状态，请求重建会使用每个 `step/start` 之后的完整持久表层前缀。

-Opt-in durable context naming the tmux session, window, and pane this agent process runs in, plus the window's pane-tree layout. It is sampled once per turn during model-request preparation and is not part of the shipped Web/headless composition. Decision record: [the tmux-context Agent Note](../../../.agents/notes/implemented/feature/2026-07-27-tmux-location-context.md).
+## Summary
 
-## Config
+`dsh-tmux-context` tells the model where its agent process runs: on each turn whose tmux state changed, it appends a durable, source-attributed reading naming the tmux session, window, and pane plus the window's pane-tree layout. It is sampled once per turn during request preparation and only when the process genuinely lives inside the named pane — a terminal that merely inherited `$TMUX`/`$TMUX_PANE` from a tmux ancestor reads as not in tmux and adds nothing. An unchanged location adds nothing, and a failed query is a no-op, never a turn failure. The plugin is opt-in and not part of the shipped Web/headless composition.

+## Use this package
+
+Mount this plugin when the agent process runs inside tmux and the model benefits from knowing its window and pane location. Each reading is one additional user-role message in durable history; an unchanged location adds nothing, so long-running sessions accumulate little.
+
+### What the agent gets
+
+On each turn whose tmux state changed, the model receives one source-tagged context message with the session name, window index and name, pane index and id, active flags, and the compact pane-tree layout. Readings happen on the first step of a turn only; a pane moved or resized mid-turn is reflected on the next turn. Pixel sizes are intentionally excluded, and the visible contents of sibling panes are never captured.
+
+### Configuration
+
+The minimal mount needs no configuration. A positive `refreshIntervalMs` additionally suppresses injections that fall within that many milliseconds of the latest one; omission or `0` injects whenever the tmux state changed since the last injection.
 
 ```yaml
-- id: tmux-context
-  name: '@deepseek-ai/dsh-tmux-context'
+- name: '@deepseek-ai/dsh-tmux-context'
   config:
-    refreshIntervalMs: 60000 # optional; omit or set to 0 to inject on every changed turn
+    refreshIntervalMs: 60000
 ```
 
-`refreshIntervalMs` must be a non-negative safe integer. Omission or `0` injects whenever the tmux state changed since the last injection. A positive value additionally suppresses injections that fall within that many milliseconds of the latest one.
+| Field | Default | Meaning |
+|---|---|---|
+| `refreshIntervalMs` | `0` (every changed turn) | Minimum milliseconds between durable injections in one session |
 
-## How it reads tmux
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-tmux-context) is the exhaustive source for every accepted field and its JSDoc.
 
-The plugin prepends an `agent/pre-step` listener that runs only on the first step of each turn. When due, it runs one read-only command through the `ctx.shell` executor service:
+### When the location is known
 
-```sh
-[ -n "$TMUX_PANE" ] || exit 1
-self_tty=$(ps -o tty= -p <pid> | tr -d ' ')
-pane_tty=$(tmux display-message -t "$TMUX_PANE" -p '#{pane_tty}') || exit 1
-[ "$pane_tty" = "/dev/$self_tty" ] || exit 1
-exec tmux display-message -t "$TMUX_PANE" -p '<format>'
-```
+The process counts as in tmux only when its controlling terminal matches the pane's `#{pane_tty}`; a terminal launched from a tmux shell (a VS Code integrated terminal, a desktop launcher) inherits the variables but not the pane, so it reads as not in tmux. A missing `ctx.shell`, an absent environment, or a malformed reading is a no-op, and an executor rejection is contained and logged as a warning rather than failing the turn.
 
-`$TMUX_PANE` alone is insufficient: a terminal launched from a tmux shell (a VS Code integrated terminal, a desktop launcher) **inherits** `$TMUX` and `$TMUX_PANE` from that ancestor, so the variables are present even though the process does not live in that pane. The command therefore also compares the pane's `#{pane_tty}` against this process's own controlling terminal (`ps -o tty=` for its pid): a genuine pane owns this process's tty, while an inherited environment names some other pane's tty. Running through `ctx.shell` applies the deployment's sandbox and policy; the plugin owns no subprocess code. When `ctx.shell` is absent, the process is not in a real tmux pane (`$TMUX_PANE` unset, or the tty does not match ⇒ nonzero exit), or the reading is malformed, the attempt is a no-op, never an error. The location is optional, so an executor rejection — a policy refusal from `resolve()` or an infrastructure failure from `run()` — is contained and logged as a warning rather than failing the turn.
+-----
 
-State is pulled on every eligible turn — a moved, renamed, or re-laid-out pane is picked up without any tmux hook or background process. The plugin re-injects only when the rendered tmux state differs from its last injection, so an unchanged location adds nothing.

-The plugin prepends an `agent/pre-step` listener. When an injection is due and the downstream decision enters the proposed step, it prepends one sourced `UserMessage` to the returned batch. AgentLoop records that context after `step/start` with source `{ kind: 'plugin', plugin: 'tmux-context' }`. Change suppression and interval scheduling scan the raw durable session events for the latest injection of this source, so the schedule survives compaction and resumed processes without process-local cache state; sessions schedule independently. A downstream pre-step listener that rejects or fails prevents the reading from being recorded.
+This section explains the design of the plugin; the observable behavior is covered in [Use this package](#use-this-package).
 
+### Design concept
+
+The plugin prepends an `agent/pre-step` listener that runs only on the first step of each turn. When due, it runs one read-only command through the `ctx.shell` executor service — the deployment's sandbox and policy apply, and the plugin owns no subprocess code. The command compares `$TMUX_PANE`'s `#{pane_tty}` with this process's own controlling terminal before emitting tab-separated fields, so an inherited environment reads as not in tmux. The plugin re-injects only when the rendered state differs from its last injection.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: first-step listener, shell query, change suppression, scheduling |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion for the snapshot contract |
+
+### Main flow
+
+At the first step of a turn, the listener checks whether an injection is due, queries the location through `ctx.shell`, and compares the rendered state with the latest durable injection of this source. Change suppression and interval scheduling scan the raw durable session events, so the schedule survives compaction and resumed processes without process-local cache state; sessions schedule independently. A downstream pre-step listener that rejects or fails prevents the reading from being recorded.

+These limits define when tmux location context is a poor fit. They are current package constraints.
+
 - **First step only** — a pane moved or resized mid-turn is reflected on the next turn, not between steps.
 - **Own location only** — the plugin never captures the visible text of sibling panes.
 - **Layout, not size** — pane/window pixel dimensions are omitted; only the layout tree and active flags are reported.
 - **Tab-delimited fields** — a tmux window name containing the literal two-character sequence `\t` would mis-split the reading and be skipped as malformed; ordinary names are unaffected.
 - **tty-based pane detection** — the process is considered "in tmux" only when its controlling terminal matches `$TMUX_PANE`'s `#{pane_tty}`. This deliberately excludes terminals that inherited `$TMUX`/`$TMUX_PANE` from a tmux ancestor (e.g. a VS Code integrated terminal). `ps -o tty=` is POSIX; the check is a no-op wherever it or `#{pane_tty}` is unavailable.

+## 使用本包
+
+当 agent 进程运行在 tmux 内、且模型需要知道其 window 与 pane 位置时，挂载此插件。每条读数都是持久历史中额外的一条 user 角色消息；位置未变化时不添加任何内容，因此长时会话累积很少。
+
+### 模型能得到什么
+
+在 tmux 状态发生变化的每一轮，模型会收到一条带来源标记的上下文消息，包含 session 名称、window 索引与名称、pane 索引与 id、活动标志，以及紧凑的 pane 树布局。读数只发生在每轮的第一个步骤；轮次中途移动或缩放的 pane 会在下一轮反映。像素尺寸有意省略，相邻 pane 的可见内容从不采集。
+
+### 配置
+
+最小挂载无需任何配置。正的 `refreshIntervalMs` 会额外抑制距最近一次注入不足该毫秒数的注入；省略或设为 `0` 时，只要 tmux 状态自上次注入以来发生变化就注入。
 
 ```yaml
-- id: tmux-context
-  name: '@deepseek-ai/dsh-tmux-context'
+- name: '@deepseek-ai/dsh-tmux-context'
   config:
-    refreshIntervalMs: 60000 # optional; omit or set to 0 to inject on every changed turn
+    refreshIntervalMs: 60000
 ```
 
-`refreshIntervalMs` 必须是非负安全整数。省略或 `0` 表示只要 tmux 状态自上次注入以来发生变化就注入。正值会额外抑制距最近一次注入不足该毫秒数的注入。
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `refreshIntervalMs` | `0`（每个变化轮次） | 同一会话中两次持久注入之间的最小毫秒数 |

-插件前置注册一个 `agent/pre-step` 监听器，仅在每轮的第一个步骤运行。当需要注入时，它通过 `ctx.shell` 执行器服务运行一条只读命令：
+### 何时知道位置
 
-```sh
-[ -n "$TMUX_PANE" ] || exit 1
-self_tty=$(ps -o tty= -p <pid> | tr -d ' ')
-pane_tty=$(tmux display-message -t "$TMUX_PANE" -p '#{pane_tty}') || exit 1
-[ "$pane_tty" = "/dev/$self_tty" ] || exit 1
-exec tmux display-message -t "$TMUX_PANE" -p '<format>'
-```
+只有当进程的控制终端与 pane 的 `#{pane_tty}` 一致时，才视为位于 tmux 中；从 tmux shell 启动的终端（VS Code 集成终端、桌面启动器）会继承变量但不在 pane 内，因此被视为不在 tmux 中。`ctx.shell` 缺失、环境变量不存在或读数格式非法时是空操作；执行器拒绝会被兜住并记录为警告，而不会使该轮失败。
 
-仅凭 `$TMUX_PANE` 并不足够：从 tmux shell 启动的终端（VS Code 集成终端、桌面启动器）会从该祖先进程**继承** `$TMUX` 与 `$TMUX_PANE`，因此即使进程并不位于那个 pane 中，这些变量依然存在。为此该命令还会把 pane 的 `#{pane_tty}` 与本进程自己的控制终端（对其 pid 执行 `ps -o tty=`）作比较：真正的 pane 拥有本进程的 tty，而继承而来的环境指向的是另一个 pane 的 tty。通过 `ctx.shell` 运行会应用部署方的沙箱与策略；插件不拥有任何子进程代码。当 `ctx.shell` 缺失、进程不在真实的 tmux pane 内（`$TMUX_PANE` 未设置，或 tty 不匹配 ⇒ 非零退出）或读取结果格式非法时，本次尝试为空操作，绝不报错。由于位置信息是可选的，执行器的拒绝——`resolve()` 的策略拒绝或 `run()` 的基础设施故障——会被兜住并记录为警告，而不会使该轮失败。
+-----
 
-状态在每个符合条件的轮次拉取——pane 被移动、改名或重新布局都会被感知，无需任何 tmux hook 或后台进程。插件仅在渲染出的 tmux 状态与上次注入不同时才重新注入，因此位置不变时不会新增任何内容。

+## Summary
+
+The core group provides the product API spine of the DeepSeek Harness: an append-only session log, system-prompt assembly, a tool registry, the `Agent` handle, and the concrete loop that drives them. Every composition boots these packages, and plugins and consumers build against their stable contracts. A turn flows through all of them — the loop claims a prompt, opens a turn on the session log, assembles the request through system-prompt, streams the model response, dispatches tool calls through the registry, and appends every model-visible fact back to the log. Choose this group when you build an agent or extend one; the runnable default composition is [`examples/agent-spine-demo`](../examples/agent-spine-demo/README.md).

-The deployment default used when an entry point creates an Agent that has no session-local model selection. `AgentDefaultModelConfig` provides `ctx.agentDefaultModel`; direct entry points such as `dsh --profile headless` and Host-backed entry points such as ApiProxy read the same service instead of owning parallel provider/model defaults.
+## Summary
 
-The plugin config requires `{ provider, model }`. That composition entry is the base of the `agent-default-model` Settings section; a mounted settings provider layers the user's choice over it and changes are visible on the next `currentSelection()` read. `reasoningEffort` belongs to the Settings section but deliberately not to plugin config: a complete saved selection can clear an effort when the next selected model has none, while a composition value would be inherited again.
+`dsh-agent-default-model` supplies the deployment's default model selection — provider, model, and optional reasoning effort — that agent entry points apply when a fresh session has no selection of its own. Direct entry points such as `dsh --profile headless` and Host-backed entry points read `ctx.agentDefaultModel` instead of owning parallel defaults, so one composition entry controls which model new agents start on. A mounted settings provider layers the user's choice over the composition entry, and a saved change is visible on the next read. It is one process-wide default: per-session model selection remains the entry point's responsibility. Choose it when you want a single place to set the model new agents use.
 
-- `ctx.agentDefaultModel.currentSelection()` returns a detached `{ provider, model, reasoningEffort? }` selection for a newly created Agent.
-- `ctx.agentDefaultModel.saveSelection(selection)` saves the complete user selection. Without a settings provider it is a no-op and the composition entry remains current.

+## Use this package
+
+Mount this package wherever agents are created without an explicit model route. The service answers one question — which model should a fresh agent use? — so entry points that create agents consult it instead of re-implementing a default.
+
+### Configure the default
+
+The composition entry is the base of the default: it requires a provider and model and stays usable without any settings provider.
+
+```yaml
+- name: '@deepseek-ai/dsh-agent-default-model'
+  config:
+    provider: deepseek
+    model: deepseek-chat
+```
+
+| Field | Default | Meaning |
+|---|---|---|
+| `provider` | required | Registered provider route for fresh agents |
+| `model` | required | Provider-owned model id for fresh agents |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-agent-default-model) is the exhaustive source for every accepted field. `reasoningEffort` is deliberately not a config field: it belongs to the settings layer, so a complete saved selection can clear an effort when the next selected model has none, while a composition value would be inherited again.
+
+### Read and change the default
+
+`currentSelection()` returns a detached `{ provider, model, reasoningEffort? }` for a newly created agent; `saveSelection()` stores the complete selection for later agents.
+
+```text
+const selection = ctx.agentDefaultModel.currentSelection()
+await ctx.agentDefaultModel.saveSelection({ provider, model, reasoningEffort: 'high' })
+```
+
+Without a settings provider, `saveSelection()` is a no-op and the composition entry remains current. The service does not validate catalog membership: a provider route may serve an unadvertised model, and the consumer that opens a model request owns availability diagnostics.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the service realizes the behavior above; the observable contract is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The service is a composition entry with a settings-backed source. The plugin config supplies the base `{ provider, model }`; when a settings provider is mounted, the `agent-default-model` settings section becomes the live source and every consumer reads through `currentSelection()`, so a settings write needs no registration-level rebuild. `reasoningEffort` lives only in the settings schema — the config cannot carry it, because an effort cleared by a new selection must stay cleared rather than being re-inherited from composition.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `AgentDefaultModelConfig` service, settings section install, `currentSelection`/`saveSelection` |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion |
+
+### Behavior notes
+
+Both public methods are thin reads and writes over that source: `currentSelection()` returns a fresh detached object so a caller can hold it without aliasing service state, and `saveSelection()` writes the whole selection through `ctx.settings` when present.

 #### KV Cache effect
 
-Changing the default affects only Agents that subsequently resolve from it. An existing session whose request log already names a selection keeps that selection, so this service does not invalidate its established prefix.

-该部署默认值供入口在创建尚无会话级模型选择的 Agent 时使用。`AgentDefaultModelConfig` 提供 `ctx.agentDefaultModel`；`dsh --profile headless` 这类直接入口与 ApiProxy 这类由 Host 支撑的入口读取同一服务，而不是分别持有平行的提供方／模型默认值。
+## 概述
 
-插件配置必须提供 `{ provider, model }`。该组合配置项构成 Settings 中 `agent-default-model` 分节的基础层；挂载的设置提供方在其上叠加用户选择，更改会在下一次调用 `currentSelection()` 时可见。`reasoningEffort` 属于该 Settings 分节，但特意不属于插件配置：完整保存的选择必须能在下一个选定模型没有推理（reasoning）强度时清除旧值，而组合配置值会再次被继承。
+`dsh-agent-default-model` 提供部署的默认模型选择——提供方、模型与可选的推理（reasoning）强度——agent 入口在全新会话没有自己的选择时应用它。`dsh --profile headless` 这类直接入口与 Host 支撑的入口读取 `ctx.agentDefaultModel`，而不是各自持有平行默认值，因此一个组合配置项就能控制新 agent 从哪个模型开始。挂载的设置提供方会把用户选择叠加在组合配置项之上，保存的更改在下一次读取时可见。它是单一的进程级默认值：按会话的模型选择仍由入口负责。想要为新建 agent 所用模型设置单一位置时，请选择本包。

+## 使用本包
+
+在创建 agent 且未显式给出模型路由的任何地方挂载本包。该服务回答一个问题——新 agent 应该使用哪个模型？——因此创建 agent 的入口查询它，而不必重新实现默认值。
+
+### 配置默认值
+
+组合配置项是默认值的基础：它要求提供方与模型，并且不依赖任何设置提供方也能使用。
+
+```yaml
+- name: '@deepseek-ai/dsh-agent-default-model'
+  config:
+    provider: deepseek
+    model: deepseek-chat
+```
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `provider` | 必填 | 新 agent 使用的已注册提供方路由 |
+| `model` | 必填 | 新 agent 使用的、由提供方持有的模型 id |
+
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-agent-default-model)是每个受支持字段的穷尽式真源。`reasoningEffort` 刻意不是配置字段：它属于设置层，因此完整保存的选择可以在下一个选定的模型没有推理强度时清除旧值，而组合配置值会再次被继承。
+
+### 读取与更改默认值
+
+`currentSelection()` 为新创建的 agent 返回一份独立的 `{ provider, model, reasoningEffort? }`；`saveSelection()` 为后续 agent 保存完整选择。
+
+```text
+const selection = ctx.agentDefaultModel.currentSelection()
+await ctx.agentDefaultModel.saveSelection({ provider, model, reasoningEffort: 'high' })
+```
+
+未挂载设置提供方时，`saveSelection()` 不执行任何操作，组合配置项仍为当前值。该服务不校验目录成员关系：提供方路由可以服务未在目录中公布的模型；发起模型请求的消费方负责可用性诊断。

+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释该服务如何实现上述行为；可观察约定已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+该服务是一个带设置后援真源的组合配置项。插件配置提供基础 `{ provider, model }`；挂载设置提供方后，`agent-default-model` 设置分节成为实时真源，所有消费方都通过 `currentSelection()` 读取，因此设置写入无需重建任何注册级事实。`reasoningEffort` 只存在于设置 schema 中——配置不能携带它，因为被新选择清除的推理强度必须保持清除，而不是从组合中再次继承。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：`AgentDefaultModelConfig` 服务、设置分节安装、`currentSelection`/`saveSelection` |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式配套 |
+
+### 行为说明
+
+两个公开方法都是对该真源的薄读写：`currentSelection()` 返回全新独立对象，调用方持有它不会别名化服务状态；`saveSelection()` 在存在 `ctx.settings` 时写入完整选择。

-THE concrete agent plugin and loop driver. Its package-internal implementation satisfies the `Agent` interface and drives the session/turn/step lifecycle.
+## Summary
 
-This is the only package in the harness that contains concrete loop logic. Everything else is an abstract service or a plugin against extension points — new behavior goes into plugins, not here.
+`dsh-agent-loop` creates agents — fresh or resumed from persisted history — and runs the turn and step lifecycle that claims prompts, assembles requests, streams model responses, dispatches tool calls, and appends every result back to the session log. As the default driver it implements the `Agent` interface from `dsh-agent` and registers its factory there, so plugins create and drive agents through `ctx.agents` without depending on this package. Declarative config entries start agents automatically at boot, and `maxParallelToolCalls` caps how many parallel-safe tool calls run at once. It is the harness's only concrete loop — everything beyond "call the model, run the tools, repeat" belongs to plugins listening on the event taxonomy. Choose it as the driver for standard compositions; swap it by implementing `Agent` and registering through `ctx.agents`.

-Creation and resume are one rollback-covered transaction: construct a private session, concrete agent, and scoped context; await optional setup; enter both registries; announce `session/created` then `agent/created`; emit `agent/session-start`; and only then start the driver. Setup receives the full scoped `Context` as trusted same-process composition code and must not drive the unpublished agent. Ordinary typed identity and option inputs are borrowed under their readonly contract, while seed events and session metadata are validated and snapshotted because they cross the durable session boundary. An optional `AbortSignal` cancels only load/setup/publication and is detached before the returned handle becomes visible.
+-----
 
-The caller fiber and the AgentLoop provider are co-owners. `AgentFactory.createAgent(ownerCtx, options)` and `resume(ownerCtx, options)` receive caller ownership explicitly, while the factory keeps its own dependency context for `sessions`/`llm`/`tools`/`systemPrompt`; this lets a caller inject only `agents` without shrinking the new agent's service set. Caller unload, handle disposal, or provider unload converge on one memoized quiescence boundary. Provider shutdown waits both resource teardown and the public create/resume wrapper that observed deactivation, so no continuation can publish after dependencies disappear.

+## Use this package
 
-Each agent and its session share one caller-chosen `SessionId`, assumed globally unique; accidental UUID collisions are outside the supported model. Two concurrent operations with the same id may both prepare, but the final `enter()` calls arbitrate publication and every loser rolls its private resources back. Each detach is bound to the exact entered object, so a stale disposer cannot remove a later same-id replacement. A detach requested during a synchronous creation notification waits for that dispatch to unwind, preserving created/disposed pairing. Teardown runs stop and drain → unwind scope → detach agent → detach session; the id becomes reusable after private scope cleanup. Ordinary non-vetoing `agent/*` notifications go through `agentEvents(ctx, agent)`, and per-step assembly goes through `assembleContextFor(agent)`.
+Mount `dsh-agent-loop` in any composition that should run agents. It supplies the driver behind `ctx.agents` and starts any agents you declare in its config; the standard demo composition is [`examples/agent-spine-demo`](../../../packages/examples/agent-spine-demo/README.md).
 
-- `ctx.agentLoop.create(id: SessionId, options?: AgentOptions, meta?: { cwd?: string }): Agent` — synchronous no-setup create under the exact shared agent/session id, disposed with the calling fiber. Declarative config treats `agents[].id` as a stable label and normally mints `${label}-session-<uuid>` before calling this boundary. An app may instead supply a stable exact `sessionId`: first use creates it, while a remount with persistence already present resumes its materialized history. `resumeSessionId` requires and loads an existing persisted id and is mutually exclusive with `sessionId`. This keeps default fresh restarts collision-free without retaining a second live routing identity.
+### Configure declarative agents
 
-`AgentLoop` also implements the `AgentFactory` contract and registers itself via `ctx.agents.setFactory(this)`, so plugins create/resume agents through `ctx.agents`:
+Agents declared in the config start automatically when the plugin loads. Each entry needs an `id` label; a model call additionally requires both `provider` and `model` (`agent/request` may supply a missing pair before dispatch).
 
-- `ctx.agents.create({ sessionId, meta?, seed?, agentOptions?, setup?, signal? }): Promise<AgentHandle>` — programmatic create under the caller-supplied shared id. It awaits the unpublished setup transaction before returning; `meta` carries cwd/lineage/seed-boundary metadata and `seed` reconstructs a forked child prefix after the session boundary validates and snapshots the durable values. `signal` applies only until this promise settles. The resolved [`AgentHandle`](../agent/README.md) owns exact teardown.
-- `ctx.agents.resume({ resumeSessionId, agentOptions?, setup?, signal? }): Promise<AgentHandle>` — load a persisted session via `ctx.sessionPersistence` ([session persistence](../../../.agents/notes/implemented/architecture/2026-06-14-session-persistence.md)), register the agent under that same id, reconstruct its history, then await setup against a fresh unpublished agent scope before rollback-covered publication. Turn numbering and derived history continue from the loaded log. Requires a session-persistence backend (NOT hard-injected — non-persistent demos still work; `resume` rejects with a clear error when persistence is absent). `signal` is creation-only. Returns an `AgentHandle`.
-
-The config-driven `ctx.agentLoop.create()` path keeps its agent owned by the loop fiber (it discards the handle). For a programmatic agent, the handle holder is the only consumer-facing teardown capability; AgentLoop provider unload is the independent structural teardown edge, not another handle exposed to application code.
-
-### Injected services
-
-`agents`, `sessions`, `llm`, `tools`, `systemPrompt` — all five interface services.
-
-### Invariant companion
-
-The optional `@deepseek-ai/dsh-agent-loop/invariant` companion registers request reconstruction with `ctx.invariants`. The loop records each exact frozen request in the process-local identity set owned by `dsh-llm`; the companion then requires a live session and independently rebuilds the message boundary and folded request header from the log. Direct one-shot calls remain outside this contract even when callers freeze them or attach a session id.
-
-### Configuration (schemastery)
-
-```ts
-interface Config {
-  maxParallelToolCalls?: number // default 10; 1 is serial
-  agents: Array<{
-    id: string                 // required
-    provider?: string
-    model?: string
-    reasoningEffort?: string  // non-empty initial reasoning effort
-    maxTokens?: number         // positive per-request output-token cap
-    resumeSessionId?: string   // load this persisted session instead of creating one
-    cwd?: string               // optional workspace cwd for the fresh session
-  }>
-}
+```yaml
+- name: '@deepseek-ai/dsh-agent-loop'
+  config:
+    maxParallelToolCalls: 10
+    agents:
+      - id: 'main'
+        provider: deepseek
+        model: deepseek-chat
+        reasoningEffort: high
+        cwd: /workspace
 ```
 
-Configured agents start automatically. A model call requires both `provider` and `model`; `agent/request` may supply a missing pair before dispatch. An optional non-empty `reasoningEffort` seeds the request's reasoning setting; `agent/request` may override it, and adapter resolution validates the effective value recorded in the request header. An optional positive `maxTokens` seeds each conversation request's output cap and is logged in its request header. `maxParallelToolCalls` bounds every agent's rolling pool for parallel-safe calls and defaults to `10`; it is also the whole of the `agent-loop` Settings section, so a user layer over this entry caps the next tool group without a restart, and a value that is not a positive integer is refused at the write rather than at that group. `agents` is deliberately absent from that section — it is consumed once when the service starts, so a stored change could only look like it had an effect. `cwd` applies only to fresh sessions, while `resumeSessionId` retains persisted metadata. Configured agents use the deployment persona, and programmatic setup can shadow it per agent. This plugin supplies the per-agent `provider`, `model`, and `cwd` prompt variables; harness identity and deployment persona belong to `dsh-system-prompt`.
+| Field | Default | Meaning |
+|---|---|---|
+| `maxParallelToolCalls` | `10` | Parallel-safe tool calls in flight per step; `1` is serial |
+| `agents[].id` | required | Stable label; a fresh session mints `${id}-session-<uuid>` unless `sessionId` is set |
+| `agents[].provider` / `agents[].model` | — | Model route; both required before dispatch |
+| `agents[].reasoningEffort` | — | Non-empty initial reasoning effort; `agent/request` may override it |
+| `agents[].maxTokens` | — | Positive per-request output-token cap |
+| `agents[].cwd` | — | Workspace directory for a fresh session |
+| `agents[].sessionId` | — | Exact identity: first use creates, a remount resumes materialized history |
+| `agents[].resumeSessionId` | — | Load this persisted session instead of creating one; mutually exclusive with `sessionId` |
 
-### Internal concrete driver
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-agent-loop) is the exhaustive source for every accepted field. The adapter validates the effective reasoning effort and the loop records it in the request header. `maxParallelToolCalls` is also the whole `agent-loop` settings section, so a user layer over this entry caps the next tool group without a restart.
 
-The concrete `ReactLoopAgent`, its inbox, and run controls are package-internal. The package root exports only the plugin/service/config contract, and the package exports map exposes no `./src/*` escape hatch; lifecycle owners create agents through `ctx.agents` rather than naming, constructing, or starting driver internals. One prepared session can be claimed by only one concrete driver, and everything observable happens through session events and the `agent/*` event taxonomy.
+### Create or resume agents programmatically
 
-The unified `send()` primitive routes content and source by (`target` × `wakeup`); `followup`/`steer`/`inject` are its fixed-preset aliases. `followup()` appends to the `next-turn` FIFO and wakes the driver, `steer()` appends to the `next-step` inbox and wakes it, and `inject()` appends to that same `next-step` inbox without waking it. At a turn boundary the driver opens the durable turn, then atomically claims pending next-step input plus one queued prompt; between steps it claims only next-step input. Claiming removes the batch through pure deletion splices and emits `agent/inbox/claimed { message, turn }` once per message. `agent/pre-step` then returns either rejection or the complete messages entering the proposed step. Rejection leaves the claimed batch removed and closes the turn without a step; input inserted after the claim remains pending, and idle injection waits until follow-up or steering wakes the driver.
+Plugins and hosts create agents through `ctx.agents.create()` and resume persisted sessions through `ctx.agents.resume()`; both return an `AgentHandle` whose `dispose()` owns exact teardown. The loop runs each created agent to completion — the handle is only needed when the caller must tear the agent down itself.
 
-Every inbox mutation publishes one normalized `agent/inbox/spliced` event before changing the live projection. Insertions, edits, removals, claiming, and cancellation replay through the same standard splice coordinates. Ordinary removals carry `outcome: 'canceled'` and emit `agent/inbox/discarded { message }`; claiming uses pure deletions with no outcome, after which the loop emits `agent/inbox/claimed`. Every insertion emits `agent/inbox/inserted { message }`. `MessageId` stays unique across both pending lists, and synchronous durable-event observers can reconstruct removed values from the pre-splice projection.
+```text
+const handle = await ctx.agents.create({
+  sessionId,
+  agentOptions: { provider: 'deepseek', model: 'deepseek-chat' },
+  setup: (agentCtx) => { /* scoped tools, prompt sections, listeners */ },
+})
+```
 
-### Loop lifecycle (`agent.ts`)
+### What a step does
 
-The driver owns one agent for its lifetime and runs inside `ctx.agents.withInitiator(agent, ...)`. Package-private orchestration entry points recover the exact Agent, derive `agent.session` once, and let operation-local helpers capture it instead of forwarding the concrete driver or per-operation `Session` through shallow interfaces. A helper keeps an explicit `Session` when that is its actual interface, while creation, persistence load, unpublished setup, services, workers, processes, persistence, and wire protocols retain their explicit identities. The [agent service](../agent/README.md#initiating-agent-scope) owns propagation, teardown, and detached-work rules.
+Each step sends the agent's rendered system prompt, its visible tool schemas, and the session's derived history; the model's tool calls run through the guarded tool pipeline and every accepted fact is appended to the session log before the next step derives from it. Parallel-safe calls may overlap up to `maxParallelToolCalls`; exclusive calls run alone as ordering barriers. Cancellation is cooperative: `agent.cancel()` aborts the current activity and, unless `keepInbox` is set, clears pending work; a cancelled stream finalizes the text already delivered to the user.
 
-Every provider call that reaches a successful finish appends exactly one `assistant/message` completion anchor, including content-less calls and `max-tokens` finishes. The anchor records the assembled content as-is, lists the exact chunk seqs in `sourceEventSeqs` (`[]` for a stream with no chunks), and includes usage when available; empty content stays out of derived message history. A turn cancellation that interrupts streaming also appends an `interrupted: true` anchor when non-empty text or reasoning has reached the user. The anchor cites those chunk seqs and places the rendered prefix in derived message history, so the next request contains what the user saw. Undispatched tool calls are omitted, and an empty or tool-only stream produces no anchor; provider failures still commit no assistant content ([decision](../../../.agents/notes/implemented/architecture/2026-08-10-cancelled-stream-prefix-finalize.md)).
+-----
 
-After `agent/request` returns a provider/model call config, the loop asks `ctx.llm.prepareCall()` to validate adapter-owned fields and materialize configured reasoning-effort and output-token defaults under the active turn signal. The prepared call retains the exact adapter registration across this asynchronous resolution, `request/header` logging, and terminal dispatch, so HMR cannot mix one adapter's capability result with another adapter's request. The header records the effective config and which fields came from the adapter. The loop appends a full snapshot for its first request, for a changed header, and when an unchanged header begins an explicitly declared message series or the first request after a surface replacement. A changed header that also begins a series carries `startsSeries: true`; further same-series Steps, ordinary later Turns, and retries with an unchanged header inherit the latest snapshot. Before the next waterfall, the loop removes adapter-marked fields from the proposal so the current exact route rematerializes its own defaults; unmarked explicit settings persist across steps and route changes. A route with no registered adapter preserves the proposed config so an `llm/stream` listener can own and short-circuit it; unhandled terminal dispatch still fails with `NO_ADAPTER`. A new loop instance follows the same adapter-default marker rule and appends a `resume` snapshot.
+<a id="understand-the-implementation"></a>
+## Understand the implementation
 
-Plugin failure ends the current turn, not the loop. Final adapter selection, dispatch, and iteration failures arrive from `ctx.llm` as terminal error or aborted finishes and enter `agent/request-error`; middleware, result processing, tools, and other extension failures remain thrown and close directly. Recovery receives request coordinates, immutable provider facts, the immutable retry policy captured by the prepared adapter registration, and the turn signal; the policy is absent when middleware owns an unprepared route. A handling listener returns `{ kind: 'retry' }`; an unhandled failure is terminal. AgentLoop owns one cancellation signal for the current admission or turn. An effective `cancel(cause)` clears pending work unless `keepInbox` is set and cooperatively aborts that signal; idle cancellation is a no-op. Waking input that lands after the abort fires but before the activity converges to idle is latched (`wakeRequested`) and replayed at the driver's own convergence boundary, so it runs without a further waking send; a `disposed` cancel never latches, and a wake submitted while already idle always opens its turn boundary (status shows a transient `idle → running → idle` pair even when the message was cleared). Durable `turn/end` records `aborted` for `user` and `parent`, while disposal records `disposed`; undispatched model tool calls receive synthetic `tool/call` and `ABORTED_BEFORE_DISPATCH` result pairs. The cancellation cause changes reporting, not how result context finalized after cancellation is handled. Disposal waits for signal-ignoring work before registry removal. The [explicit-cancellation decision](../../../.agents/notes/implemented/architecture/2026-07-16-explicit-turn-cancellation.md) and the [cancel-convergence wake latch](../../../.agents/notes/implemented/bug-fix/2026-08-07-cancel-convergence-wake-latch.md) own the lifecycle and race contract.

+<summary>Implementation internals — click to expand</summary>
 
-Within a step, exclusive calls form barriers; parallel-safe calls use a bounded rolling pool and are reclassified before start. Only dispatch/body overlaps. Policy, durable results, and result context remain model-ordered. Abort stops new calls, drains started results, and retains their finalized result context without distinguishing the cancellation cause. An internal scheduler failure stops new dispatches, waits for already-started dispatches, and reaches the turn error boundary without fabricating tool results.
+This section explains how the package realizes the behavior above; the observable contract is covered in [Use this package](#use-this-package).
 
-### What belongs to plugins
+### Design concept
 
-Everything that goes beyond "call the model, run the tools, repeat" belongs to plugins listening on the event taxonomy:
-- Hooks and policy: the relevant `agent/*` checkpoints plus the guarded `tools/pre-execute` → `tools/execute` → `tools/post-execute` → definition-owned `finalizeContent` → `tools/result` pipeline; exact event signatures and modes live in the generated regions of [core.md](../../../docs/subsystems/core.md#cordis-surface) and [tools.md](../../../docs/subsystems/tools.md#cordis-surface)
-- Compaction: pressure on `agent/pre-step`; canonical overflow repair on `agent/request-error`
-- Model-request recovery: `dsh-llm-retry` records and waits exact-provider normal or unbounded backoff on `agent/request-error`, emits non-surface `llm/retry` status, then returns a retry action
-- Sandbox, permission, plan mode: `tools/pre-execute` for extensible deny/ask, `tools.guard()` for monotonic owner policy, `tools/post-execute` for result decisions, and `tools/result` for final observation
-- Sub-agents: implemented outside the loop as `ctx.subagents` providers; in-process providers use `ctx.agents.create()` and owned `AgentHandle` teardown, while generic [`ctx.jobs`](../../jobs/jobs/) plus [`dsh-tool-subagent`](../../subagent/tool-subagent/) own background collection.
-- Persistence: eager write-behind from `session/event`; `session/flush` is an explicit observation barrier
-- UI: `session/event` (assistant token stream, boundaries, tool activity) + `agent/*` control events (`agent/status`, `agent/created`/`agent/disposed`)
+The package is the one concrete implementation of the public `Agent` contract. It registers itself as the `AgentFactory` on `ctx.agents`, so consumers never import this package; ownership of each created agent lives with the caller fiber and the loop provider, converging on one memoized quiescence boundary. Every observable effect happens through session events and the `agent/*` taxonomy — package internals are never part of the public surface.
 
+### Request headers and adapter defaults
+
+After `agent/request`, `ctx.llm.prepareCall()` validates adapter-owned fields and resolves reasoning-effort and output-token defaults under the active turn signal. The loop retains that exact adapter through resolution, `request/header` logging, and dispatch. It writes a full header for the first request, a changed envelope, an explicit message-series start, a request after surface replacement, and resume; unchanged steps, retries, and ordinary later turns in the same series inherit the latest header. Before the next waterfall, the loop removes adapter-default fields so the current route resolves them again, while explicit settings persist. An unhandled route still fails with `NO_ADAPTER`.

+
+### Creation and teardown
+
+Creation is one rollback-covered transaction: construct a private session, concrete agent, and scoped context; await optional setup; enter both registries; announce `session/created` then `agent/created`; emit `agent/session-start`; only then start the driver. A setup throw, commit failure, or owner disposal rolls the transaction back without publishing either id. Teardown runs stop-and-drain, unwind the scope, detach the agent, then detach the session, and every detach is bound to the exact entered object so a stale disposer cannot remove a later same-id replacement.
+
+### Turn and step flow
+
+The driver owns one agent for its lifetime and runs inside `ctx.agents.withInitiator(agent, ...)`. At a turn boundary it opens the durable turn, then atomically claims pending next-step input plus one queued prompt; between steps it claims only next-step input. `agent/pre-step` decides what enters the step; each successful model call appends one `assistant/message` anchor citing its chunk seqs, and a cancelled stream appends an `interrupted: true` anchor with the delivered prefix so the next request contains what the user saw. Within a step, exclusive calls form barriers and parallel-safe calls use the bounded rolling pool; policy, durable results, and result context remain model-ordered.
+
+### Failure and cancellation
+
+Final adapter selection, dispatch, and iteration failures arrive as terminal finishes and enter `agent/request-error`; a handling listener returns `{ kind: 'retry' }` without calling `next()`, while an unhandled failure is terminal. Middleware, result-processing, tool, and other extension failures remain thrown and close the turn directly — plugin failure ends the turn, not the loop. Undispatched model tool calls after cancellation receive synthetic `tool/call` plus `ABORTED_BEFORE_DISPATCH` result pairs. The [explicit-cancellation decision](../../../.agents/notes/implemented/architecture/2026-07-16-explicit-turn-cancellation.md) owns the signal lifecycle.

-agent（智能体）的唯一具体实现插件和循环驱动器。其包内部实现满足 `Agent` 接口，并驱动会话、轮次和步骤的生命周期。
+## 概述
 
-这是 harness 中唯一包含具体循环逻辑的包。其他所有内容要么是抽象服务，要么是针对扩展点的插件：新行为应放入插件，而不是这里。
+`dsh-agent-loop` 创建 agent——全新创建或从持久化历史恢复——并运行轮次与步骤生命周期：领取提示词、组装请求、流式接收模型响应、分发工具调用，并把每个结果追加回会话日志。作为默认驱动器，它实现 `dsh-agent` 的 `Agent` 接口并在此注册工厂，因此插件通过 `ctx.agents` 创建与驱动 agent，而不必依赖本包。声明式配置项会在启动时自动启动 agent，`maxParallelToolCalls` 限制同时运行的并行安全工具调用数量。它是 harness 唯一的具象循环——超出「调用模型、运行工具、重复」的所有内容都属于监听事件分类体系的插件。标准组合请选择它作为驱动器；如需替换，请实现 `Agent` 并通过 `ctx.agents` 注册。

-创建与恢复属于同一个受回滚保护的事务：构造私有会话、具体 agent 和带作用域的上下文；等待可选 setup；进入两个注册表；依次宣告 `session/created` 和 `agent/created`；发出 `agent/session-start`；此后才启动驱动器。Setup 作为受信任的同进程组合代码，接收完整的带作用域 `Context`，并且不得驱动尚未发布的 agent。普通的类型化身份与选项输入按只读约定借用；seed 事件和会话元数据会跨越持久会话边界，因此系统会对其进行验证并创建快照。可选的 `AbortSignal` 只取消加载／setup／发布，并在返回的 handle 可见前分离。
+-----
 
-调用方 fiber 与 AgentLoop 提供方共同拥有 agent。`AgentFactory.createAgent(ownerCtx, options)` 与 `resume(ownerCtx, options)` 显式接收调用方所有权，而工厂为 `sessions`/`llm`/`tools`/`systemPrompt` 保留自身的依赖上下文；这样，调用方可以只注入 `agents`，而不会缩减新 agent 的服务接口。调用方卸载、handle dispose（资源释放）或提供方卸载都会汇合到同一个记忆化的完全停稳边界。提供方关闭会同时等待资源 teardown，以及已经观测到停用的公开 create/resume 包装层，因此依赖消失后，任何 continuation 都无法继续发布。
+<a id="use-this-package"></a>
+## 使用本包
 
-每个 agent 与其会话共享一个由调用方选择的 `SessionId`，并假设它在全局唯一；意外的 UUID 冲突不属于受支持模型。两个使用同一 id 的并发操作都可以进行准备，但最终的 `enter()` 调用会裁决发布，所有失败方都会回滚各自的私有资源。每次 detach 都绑定到确切进入的对象，因此陈旧 disposer 无法移除之后出现的同 id 替代项。在同步创建通知期间请求的 detach 会等待该次分发退栈，从而保留 created/disposed 配对。Teardown 按以下顺序执行：停止并排空 → 撤销作用域 → detach agent → detach 会话。私有作用域清理完成后，该 id 即可复用。不具否决能力的普通 `agent/*` 通知通过 `agentEvents(ctx, agent)` 发出；逐步骤组装通过 `assembleContextFor(agent)` 完成。
+在任何应运行 agent 的组合中挂载 `dsh-agent-loop`。它提供 `ctx.agents` 背后的驱动器，并启动你在配置中声明的 agent；标准演示组合是 [`examples/agent-spine-demo`](../../../packages/examples/agent-spine-demo/README.zh.md)。
 
-- `ctx.agentLoop.create(id: SessionId, options?: AgentOptions, meta?: { cwd?: string }): Agent`：在确切共享的 agent／会话 id 下同步创建，不运行 setup，并随调用方 fiber 一同 dispose。声明式配置把 `agents[].id` 视为稳定 label，通常会先生成 `${label}-session-<uuid>`，再调用此边界。应用也可以提供稳定且确切的 `sessionId`：首次使用时创建；重新挂载且持久化内容已存在时，则恢复已经实体化的历史。`resumeSessionId` 要求并加载现有的持久化 id，且与 `sessionId` 互斥。这样，默认情况下每次重启都会创建新会话，从而避免冲突，也无需保留第二个实时路由身份。
+### 配置声明式 agent
 
-`AgentLoop` 还实现 `AgentFactory` 约定，并通过 `ctx.agents.setFactory(this)` 注册自身，因此插件会通过 `ctx.agents` 创建／恢复 agent：
+配置中声明的 agent 会在插件加载时自动启动。每个条目需要一个 `id` 标签；模型调用还同时需要 `provider` 与 `model`（`agent/request` 可以在分发前补齐缺失的这一对值）。
 
-- `ctx.agents.create({ sessionId, meta?, seed?, agentOptions?, setup?, signal? }): Promise<AgentHandle>`：使用调用方提供的共享 id 以编程方式创建。它会等待尚未发布的 setup 事务，然后才返回；`meta` 携带 cwd／谱系／seed 边界元数据，`seed` 则在会话边界验证并快照持久值后，重建 fork 子级的前缀。`signal` 只在此 Promise 结算前生效。返回的 [`AgentHandle`](../agent/README.zh.md) 拥有确切的 teardown 能力。
-- `ctx.agents.resume({ resumeSessionId, agentOptions?, setup?, signal? }): Promise<AgentHandle>`：通过 `ctx.sessionPersistence` 加载持久化会话（参见[会话持久化](../../../.agents/notes/implemented/architecture/2026-06-14-session-persistence.zh.md)），使用同一 id 注册 agent，重建历史，然后针对全新且尚未发布的 agent 作用域等待 setup，再执行受回滚保护的发布。轮次编号和派生历史从已加载日志继续。此操作要求存在会话持久化后端（不会硬注入，因此非持久化 demo 仍能工作；缺少持久化时，`resume` 会以明确错误拒绝）。`signal` 仅用于创建。返回 `AgentHandle`。
-
-配置驱动的 `ctx.agentLoop.create()` 路径让循环 fiber 拥有其 agent（该路径会丢弃 handle）。对于以编程方式创建的 agent，handle 持有者是唯一面向消费方的 teardown 能力；AgentLoop 提供方卸载是一条独立的结构性 teardown 边，而不是向应用代码公开的另一个 handle。
-
-### 注入的服务
-
-`agents`、`sessions`、`llm`、`tools`、`systemPrompt`：全部 5 个接口服务。
-
-### 不变量配套入口
-
-可选的 `@deepseek-ai/dsh-agent-loop/invariant` 配套入口会向 `ctx.invariants` 注册请求重建。循环会把每个确切的冻结请求记录在 `dsh-llm` 拥有的进程本地身份集合中；随后，配套入口要求存在实时会话，并根据日志独立重建消息边界和折叠后的请求 header。即使调用方冻结直接的一次性调用，或为其附加会话 id，这类调用仍不属于该约定。
-
-### 配置（Schemastery）
-
-```ts
-interface Config {
-  maxParallelToolCalls?: number // default 10; 1 is serial
-  agents: Array<{
-    id: string                 // required
-    provider?: string
-    model?: string
-    reasoningEffort?: string  // non-empty initial reasoning effort
-    maxTokens?: number         // positive per-request output-token cap
-    resumeSessionId?: string   // load this persisted session instead of creating one
-    cwd?: string               // optional workspace cwd for the fresh session
-  }>
-}
+```yaml
+- name: '@deepseek-ai/dsh-agent-loop'
+  config:
+    maxParallelToolCalls: 10
+    agents:
+      - id: 'main'
+        provider: deepseek
+        model: deepseek-chat
+        reasoningEffort: high
+        cwd: /workspace
 ```
 
-通过配置创建的 agent 会自动启动。模型调用同时需要 `provider` 和 `model`；`agent/request` 可以在分发前补齐缺失的这一对值。可选的非空 `reasoningEffort` 会提供请求的初始推理强度；`agent/request` 可以覆盖它，适配器解析会校验记录在请求 header 中的最终值。可选的正数 `maxTokens` 会为每次对话请求提供初始输出上限，并记录在请求 header 中。`maxParallelToolCalls` 限制每个 agent 针对并行安全调用使用的滚动池，默认值为 `10`；它同时也是 `agent-loop` Settings 段的全部内容，因此叠加在该条目之上的用户层无需重启即可限制下一组工具调用，而非正整数的值会在写入时被拒绝，而不是到那一组时才失败。`agents` 刻意不在该段中——它在服务启动时被消费一次，所以存储的改动只会看起来生效。`cwd` 仅应用于全新会话，而 `resumeSessionId` 保留持久化元数据。通过配置创建的 agent 使用部署 persona；编程式 setup 可以按 agent 遮蔽它。该插件为每个 agent 提供 `provider`、`model` 和 `cwd` 提示词变量；harness 身份与部署 persona 属于 `dsh-system-prompt`。
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `maxParallelToolCalls` | `10` | 每个步骤同时在途的并行安全工具调用数；`1` 为串行 |
+| `agents[].id` | 必填 | 稳定标签；未设置 `sessionId` 时，全新会话会生成 `${id}-session-<uuid>` |
+| `agents[].provider` / `agents[].model` | — | 模型路由；分发前两者都必须存在 |
+| `agents[].reasoningEffort` | — | 非空的初始推理等级；`agent/request` 可以覆盖它 |
+| `agents[].maxTokens` | — | 正数的逐请求输出 token 上限 |
+| `agents[].cwd` | — | 全新会话的工作目录 |
+| `agents[].sessionId` | — | 确切身份：首次使用创建，重新挂载时恢复已实体化的历史 |
+| `agents[].resumeSessionId` | — | 加载这个持久化会话而不是创建新会话；与 `sessionId` 互斥 |
 
-### 包内部具体驱动器
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-agent-loop)是每个受支持字段的穷尽式真源。适配器会校验有效推理等级，循环则把它记录在请求头中。`maxParallelToolCalls` 也是整个 `agent-loop` 设置分节，因此叠加在该条目之上的用户层无需重启即可限制下一组工具调用。
 
-具体 `ReactLoopAgent`、其 inbox 与运行控制均为包内部实现。包根只导出插件／服务／配置约定，包导出映射不提供 `./src/*` 逃逸路径；生命周期拥有方通过 `ctx.agents` 创建 agent，而不是点名、构造或启动驱动器内部组件。一个准备完成的会话只能由一个具体驱动器认领；所有可观测行为都通过会话事件和 `agent/*` 事件分类体系发生。
+### 以编程方式创建或恢复 agent
 
-统一的 `send()` 原语按（`target` × `wakeup`）路由内容与来源；`followup`/`steer`/`inject` 是它的固定预设别名。`followup()` 追加到 `next-turn` FIFO 并唤醒驱动器，`steer()` 追加到 `next-step` inbox 并唤醒驱动器，`inject()` 则追加到同一个 `next-step` inbox，但不唤醒驱动器。在轮次边界，驱动器会先打开持久轮次，再原子领取待处理的 next-step 输入和一条排队提示词；在步骤之间则只领取 next-step 输入。领取操作通过仅执行删除的 splice 移除整批消息，并为每条消息各发出一次 `agent/inbox/claimed { message, turn }`。随后 `agent/pre-step` 返回拒绝结果，或返回将进入拟议步骤的完整消息。拒绝后，已领取批次保持已删除，并关闭不含步骤的轮次；领取后插入的输入仍等待后续处理，而空闲注入会一直等待，直到 follow-up 或 steering 唤醒驱动器。
+插件与宿主通过 `ctx.agents.create()` 创建 agent，通过 `ctx.agents.resume()` 恢复持久化会话；两者都返回 `AgentHandle`，其 `dispose()` 拥有确切的 teardown 能力。循环会把每个创建的 agent 运行到完成——只有调用方需要自行拆除 agent 时才需要句柄。
 
-每次 inbox 变更都会在修改实时投影之前，先发布一条规范化的 `agent/inbox/spliced` 事件。因此，插入、编辑、移除、领取与取消都通过同一组标准 splice 坐标回放。普通删除携带 `outcome: 'canceled'` 并发出 `agent/inbox/discarded { message }`；领取使用不带 outcome 的纯删除，随后由循环发出 `agent/inbox/claimed`。每次插入都会发出 `agent/inbox/inserted { message }`。`MessageId` 在两个待处理列表之间保持唯一，持久事件的同步观察方可以从 splice 前投影重建被移除的值。
+```text
+const handle = await ctx.agents.create({
+  sessionId,
+  agentOptions: { provider: 'deepseek', model: 'deepseek-chat' },
+  setup: (agentCtx) => { /* scoped tools, prompt sections, listeners */ },
+})
+```
 
-### 循环生命周期（`agent.ts`）
+### 一个步骤做什么
 
-驱动器在其整个生命周期内拥有一个 agent，并在 `ctx.agents.withInitiator(agent, ...)` 内运行。包私有的编排入口点会恢复确切的 Agent，一次性派生 `agent.session`，并让操作局部的辅助函数捕获它，而不是通过浅层接口继续传递具体驱动器或每次操作的 `Session`。如果显式 `Session` 正是辅助函数的实际接口，该辅助函数会保留它；创建、持久化加载、未发布 setup、服务、worker、进程、持久化和 wire 协议则继续保留各自的显式身份。[agent 服务](../agent/README.zh.md#initiating-agent-scope)规定传播、teardown 和分离工作规则。
+每个步骤都会发送该 agent 渲染后的系统提示词、其可见工具 schema 与会话的派生历史；模型的工具调用经过受守卫的工具流水线，每个被接纳的事实都会在下一步据此派生之前追加到会话日志。并行安全调用最多可重叠 `maxParallelToolCalls` 个；独占调用单独运行并构成排序屏障。取消是协作式的：`agent.cancel()` 中止当前活动，并在未设置 `keepInbox` 时清除待处理工作；被取消的流会终结已送达用户的文本。
 
-每次提供方调用成功结束时，都会恰好追加一个 `assistant/message` 完成锚点，包括无内容调用和以 `max-tokens` 结束的调用。该锚点原样记录组装后的内容，在 `sourceEventSeqs` 中列出确切的分片 seq（流没有分片时为 `[]`），并在用量可用时包含用量；空内容不会进入派生消息历史。轮次取消打断流式输出时，如果非空文本或推理内容已送达用户，循环也会追加一个带 `interrupted: true` 的锚点。该锚点引用对应的分片 seq，并把已渲染的前缀放入派生消息历史，使下一次请求包含用户看到的内容。未分派的工具调用会被省略，空流或只包含工具调用的流不会生成锚点；提供方故障也不提交 assistant 内容（[决策](../../../.agents/notes/implemented/architecture/2026-08-10-cancelled-stream-prefix-finalize.zh.md)）。
+-----
 
-在 `agent/request` 返回提供方／模型调用配置后，循环会调用 `ctx.llm.prepareCall()`，在活跃轮次信号的控制下校验由适配器持有的字段，并填入配置的推理（reasoning）强度和输出 token 默认值。准备完成的调用会在这次异步解析、`request/header` 日志记录和最终分派期间保留同一项确切的适配器注册，因此 HMR（热模块替换）不会把某个适配器的能力解析结果与另一适配器的请求混用。请求 header 会记录生效配置以及哪些字段来自适配器。循环会为实例的首个请求、发生变化的 header，以及显式声明的新消息序列或表层替换后的首个请求中内容未变的 header 追加完整快照。如果变化的 header 同时开启序列，它会携带 `startsSeries: true`；同一序列内 header 未变的后续 Step、普通后续 Turn 与重试继承最新快照。下一次 waterfall（瀑布式事件）前，循环会从提议中移除由适配器标记的字段，使当前精确路由重新填入自身默认值；未带标记的显式设置会跨步骤和路由变化保留。没有已注册适配器的路由会保留原定配置，使 `llm/stream` 监听器可以接管并短路该请求；最终分派仍会以 `NO_ADAPTER` 拒绝未得到处理的路由。新循环实例在恢复时会遵循同一套适配器默认值标记规则，并追加 `resume` 快照。
+<a id="understand-the-implementation"></a>
+## 理解实现
 
-插件失败会结束当前轮次，而不是结束循环。最终适配器选择、分发与迭代失败会以终止错误或中止结束的形式由 `ctx.llm` 传来，并进入 `agent/request-error`；middleware、结果处理、工具及其他扩展失败仍会抛出并直接关闭轮次。恢复逻辑会接收请求坐标、不可变的提供方事实、准备完成的适配器注册所捕获的不可变重试策略以及轮次信号；middleware 接管未准备路由时，该策略缺失。处理失败的监听器返回 `{ kind: 'retry' }`；未被处理的失败是终态。AgentLoop 为当前准入操作或轮次拥有一个取消信号。有效的 `cancel(cause)` 在未设置 `keepInbox` 时清除待处理工作，并以协作方式中止该信号；空闲取消是空操作。abort 触发后、活动收敛到空闲前到达的唤醒输入会被锁存（`wakeRequested`），并在 driver 自身的收敛边界重放，无需再发一条唤醒 send 即可执行；`disposed` 取消从不锁存，而 agent 已处于空闲时发送的唤醒总是打开自己的 turn 边界（即使消息已被清除，状态也会显示瞬态 `idle → running → idle` 对）。持久 `turn/end` 为 `user` 和 `parent` 记录 `aborted`，dispose 则记录 `disposed`；未分发的模型工具调用会收到合成的 `tool/call` 与 `ABORTED_BEFORE_DISPATCH` 结果对。取消原因只影响报告方式，不影响如何处理在取消后完成终结的结果上下文。dispose 会等待忽略信号的工作完成，然后才从注册表移除。[显式取消决策](../../../.agents/notes/implemented/architecture/2026-07-16-explicit-turn-cancellation.zh.md)与[取消收敛窗口唤醒锁存](../../../.agents/notes/implemented/bug-fix/2026-08-07-cancel-convergence-wake-latch.zh.md)规定生命周期与竞态约定。

+<summary>实现细节——点击展开</summary>
 
-在步骤内，独占调用形成屏障；并行安全调用使用有界滚动池，并在启动前重新分类。只有分发和调用主体的执行会发生重叠。策略、持久结果和结果上下文仍保持模型顺序。中止会阻止启动新的调用，等待已启动调用的结果处理完毕，并保留其完成终结后的结果上下文，不区分取消原因。内部调度器故障会停止新的分发，等待已启动的分发，然后在不虚构工具结果的情况下到达轮次错误边界。
+本节解释该包如何实现上述行为；可观察约定已在[使用本包](#use-this-package)中完整说明。
 
-### 插件负责的内容
+### 设计理念
 
-超出「调用模型、运行工具、重复」的所有内容，都属于监听事件分类体系的插件：
-- 钩子与策略：相关的 `agent/*` 检查点，加上受守卫保护的 `tools/pre-execute` → `tools/execute` → `tools/post-execute` → 定义拥有的 `finalizeContent` → `tools/result` 流水线；确切事件签名与 mode 位于 [core.md](../../../docs/subsystems/core.zh.md#cordis-surface) 与 [tools.md](../../../docs/subsystems/tools.zh.md#cordis-surface) 的生成区块
-- 压缩（compaction）：在 `agent/pre-step` 上观测压力；在 `agent/request-error` 上进行规范的溢出修复
-- 模型请求恢复：`dsh-llm-retry` 在 `agent/request-error` 上记录并等待针对确切提供方配置的 normal 或无界退避，发出不进入表层的 `llm/retry` 状态，然后返回重试动作
-- 沙箱、权限、计划模式：使用 `tools/pre-execute` 提供可扩展的拒绝／询问，使用 `tools.guard()` 提供单调拥有方策略，使用 `tools/post-execute` 处理结果决定，并使用 `tools/result` 进行最终观测
-- subagent：在循环外部实现为 `ctx.subagents` 提供方；进程内提供方使用 `ctx.agents.create()` 创建 agent，并通过其拥有的 `AgentHandle` 执行 teardown，而通用的 [`ctx.jobs`](../../jobs/jobs/) 与 [`dsh-tool-subagent`](../../subagent/tool-subagent/) 负责后台收集。
-- 持久化：`session/event` 发生后立即安排延后写入；`session/flush` 是显式观测屏障
-- UI：`session/event`（assistant token 流、边界、工具活动）+ `agent/*` 控制事件（`agent/status`、`agent/created`/`agent/disposed`）
+该包是公开 `Agent` 约定的唯一具象实现。它在 `ctx.agents` 上把自身注册为 `AgentFactory`，因此消费方从不导入本包；每个创建 agent 的所有权归属于调用方 fiber 与循环提供方，并汇合到同一个记忆化的完全停稳边界。每个可观察效果都通过会话事件与 `agent/*` 分类体系发生——包内部从不属于公开表面。
 
+### 请求 header 与适配器默认值
+
+`agent/request` 返回后，`ctx.llm.prepareCall()` 会在活跃轮次信号下校验适配器持有的字段，并解析推理强度和输出 token 默认值。循环会在解析、`request/header` 记录与分派期间保留同一个适配器。循环会为首次请求、变化的 envelope、显式消息序列起点、表层替换后的请求及恢复写入完整 header；同一序列内内容未变的步骤、重试与普通后续轮次继承最新 header。下一次 waterfall 前，循环移除适配器默认字段，使当前路由重新解析它们；显式设置则保留。未处理的路由仍以 `NO_ADAPTER` 失败。

+### 创建与拆除
+
+创建是同一个受回滚保护的事务：构造私有会话、具象 agent 与带作用域上下文；等待可选 setup；进入两个注册表；依次宣告 `session/created` 与 `agent/created`；发出 `agent/session-start`；此后才启动驱动器。Setup 抛出、commit 失败或所有者 dispose 都会回滚事务而不发布任一 id。Teardown 顺序是停止并排空、撤销作用域、detach agent、再 detach 会话，且每次 detach 都绑定到确切进入的对象，因此陈旧 disposer 无法移除之后出现的同 id 替代项。
+
+### 轮次与步骤流程
+
+驱动器在其整个生命周期内拥有一个 agent，并在 `ctx.agents.withInitiator(agent, ...)` 内运行。在轮次边界，它先打开持久轮次，再原子领取待处理的 next-step 输入与一条排队提示词；在步骤之间则只领取 next-step 输入。`agent/pre-step` 决定什么进入该步骤；每次成功的模型调用都恰好追加一个引用其分片 seq 的 `assistant/message` 锚点，被取消的流则追加带 `interrupted: true` 的锚点并携带已交付前缀，使下一次请求包含用户看到的内容。在步骤内，独占调用形成屏障，并行安全调用使用有界滚动池；策略、持久结果与结果上下文保持模型顺序。
+
+### 失败与取消
+
+最终适配器选择、分发与迭代失败以终止结束的形式到达并进入 `agent/request-error`；拥有恢复权的监听器返回 `{ kind: 'retry' }` 且不调用 `next()`，未被处理的失败则是终态。Middleware、结果处理、工具及其他扩展失败仍会抛出并直接关闭轮次——插件失败结束的是轮次，不是循环。取消后未分发的模型工具调用会收到合成的 `tool/call` 加 `ABORTED_BEFORE_DISPATCH` 结果对。[显式取消决策](../../../.agents/notes/implemented/architecture/2026-07-16-explicit-turn-cancellation.zh.md) 拥有信号生命周期。

+## Summary
 
-## Why a row rather than a registry
+An [agent preset](../../preset/agent-presets/README.md) carries `dsh-agent-tool-presentation` to choose which form of its tools the model sees: `native` (every visible schema), `code` (only `run_code` plus a generated SDK), or `both`. The tool registry itself stays on the host plane — this row only declares the presentation for the mounting agent, so a Code Mode session runs beside native ones in one process, each seeing its own catalog. A code mode waits for a code runtime before mounting, so a preset selecting Code Mode against a deployment without one fails at mount instead of at the first prompt. The `mode` field is required: a preset without this row already gets the deployment default. Choose it when an agent preset needs to fix the tool form its agents' models see.
 
-The tool registry cannot move into a preset. Its consumers are all host-plane — [`dsh-agent-loop`](../agent-loop/README.md) reads its scheduler, [`dsh-apiproxy`](../../host/apiproxy/README.md) reads its presenters to render tool cards, and every tool plugin registers into it — and a service only moves down when all of its consumers move with it.

-What a preset can own is the **presentation** of that registry. `ctx.tools.presentAs()` declares it for the mounting agent alone, so a Code Mode session runs beside native ones in one process, each seeing its own catalog. The deployment's `mode` on the [`dsh-tools`](../tools/README.md) row remains the default that agents declaring nothing get.

-## What it does
+-----
 
-`native` applies immediately. A code mode instead waits for `ctx.codeRuntime`, which is a host-plane service ([`dsh-code-runtime-worker-thread`](../../code-runtime/code-runtime-worker-thread/README.md)): a preset selecting Code Mode against a deployment composing no runtime then holds this row pending, and `dsh-agent-presets` refuses the mount naming this id. The alternative — applying optimistically — moves the failure to the session's first request, where the operator can act on neither the preset nor the composition.
+<a id="use-this-package"></a>
+## Use this package
 
-`mode` is required rather than defaulted, because a preset without this row already gets the deployment default; an omitted value would mean the row was composed for nothing.
+Add this row to an agent preset to fix how every agent joined to that preset sees its tools. `native` presents each visible tool schema as a function definition; `code` presents only the `run_code` transport plus a generated SDK and the rule that only `run_code` may be called directly; `both` presents both forms. Agents that declare nothing get the deployment-wide `mode` on the [`dsh-tools`](../tools/README.md) row.
+
+### Add the row to a preset
+
+```yaml
+- name: '@deepseek-ai/dsh-agent-tool-presentation'
+  config:
+    mode: code
+```
+
+| Field | Default | Meaning |
+|---|---|---|
+| `mode` | required | `native` — every schema; `code` — `run_code` plus generated SDK; `both` — both forms |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-agent-tool-presentation) is the exhaustive source for every accepted field. `mode` is required rather than defaulted because a preset without this row inherits the deployment default.
+
+### What code mode requires
+
+Selecting `code` or `both` needs a composed code runtime (`ctx.codeRuntime`) whose language has a registered SDK renderer — the TypeScript runtime ships via [`dsh-code-runtime-worker-thread`](../../code-runtime/code-runtime-worker-thread/README.md), and both the TypeScript and Python SDK renderers are built into `dsh-tools`. A preset that selects a code mode against a deployment composing no such runtime refuses to mount, naming this row, so the failure lands where the operator can act instead of at the session's first request.
+
+### One presentation per agent
 
 One agent declares one presentation. A second declaration in the same composition is refused rather than merged: two answers to "which form does the model see" is a contradiction, not an override.

+
+This section explains how the package realizes the behavior above; the observable contract is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The tool registry cannot move into a preset: its consumers are all host-plane — the agent loop reads its scheduler, the API proxy reads its presenters, and every tool plugin registers into it — and a service only moves down when all of its consumers move with it. What a preset can own is the presentation of that registry. `ctx.tools.presentAs()` declares it for the mounting scope, which is the preset's standing mount, so the declaration covers every agent joined to that preset and a Code Mode preset runs beside native ones in one process. One row per composition, not one per session.

+### Source map

+| File | Role |

+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion |
+
+### Behavior notes
+
+`native` applies immediately. A code mode instead waits for `ctx.codeRuntime`, a host-plane service: a preset selecting Code Mode against a deployment composing no runtime holds this row pending, and `dsh-agent-presets` refuses the mount naming this id. `presentAs` is itself the effect, so the declaration unwinds with this row without a second wrapper owning it.

-Indirectly, through the projection it selects in `dsh-tools`: `code` presents `run_code` plus a generated SDK section and the rule that only `run_code` may be called directly, `native` presents every tool schema. The selection also decides what may EXECUTE: under `code` the registry resolves a model-direct call naming any other tool to `UNKNOWN_TOOL`, so this row is what keeps the announced surface and the callable surface the same for every agent it covers ([executor-collapse note](../../../.agents/notes/implemented/bug-fix/2026-08-07-code-mode-executor-collapse.md)).

+## 概述
 
-## 为什么是一行插件，而不是把注册表搬下来
+[agent preset](../../preset/agent-presets/README.zh.md) 携带 `dsh-agent-tool-presentation`，用来声明「模型看到其工具的哪一种形态」：`native`（每个可见 schema）、`code`（只有 `run_code` 加一份生成的 SDK）或 `both`。工具注册表本身仍在宿主平面——这一行只声明挂载 agent 的呈现方式，因此一个 Code Mode 会话可以与多个 native 会话同进程并存，各自看到各自的目录。code 类模式在挂载前会等待代码运行时，因此针对未组装运行时的部署选择 Code Mode 的 preset 会在挂载时失败，而不是在第一次请求时失败。`mode` 字段是必填的：不带这一行的 preset 本来就会拿到部署默认值。当 agent preset 需要固定其 agent 的模型所看到的工具形态时，请选择本包。

-## 它做什么
+-----
 
-`native` 立即生效。code 类模式则等待 `ctx.codeRuntime`——这是一个宿主平面服务（[`dsh-code-runtime-worker-thread`](../../code-runtime/code-runtime-worker-thread/README.zh.md)）：若某个 preset 在未组装运行时的部署上选择 Code Mode，本行就停在 pending，`dsh-agent-presets` 会指名此 id 拒绝挂载。另一种做法——先乐观应用——会把失败推迟到该会话的第一次请求，那时操作者对 preset 和组装都已无从下手。
+<a id="use-this-package"></a>
+## 使用本包
 
-`mode` 是必填而非有默认值：不带这一行的 preset 本来就会拿到部署默认值，省略它等于这一行白组装了。
+把这一行加入 agent preset，以固定每个加入该 preset 的 agent 看到其工具的方式。`native` 以函数定义的形式呈现每个可见工具 schema；`code` 只呈现 `run_code` 传输、一份生成的 SDK 以及「只有 `run_code` 可被直接调用」这条规则；`both` 同时呈现两种形态。未作声明的 agent 会拿到 [`dsh-tools`](../tools/README.zh.md) 那一行上的部署级 `mode`。
+
+### 把这一行加入 preset
+
+```yaml
+- name: '@deepseek-ai/dsh-agent-tool-presentation'
+  config:
+    mode: code
+```
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `mode` | 必填 | `native`——每个 schema；`code`——`run_code` 加生成 SDK；`both`——两种形态 |
+
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-agent-tool-presentation)是每个受支持字段的穷尽式真源。`mode` 是必填而非有默认值，因为不带这一行的 preset 会继承部署默认值。
+
+### code 模式需要什么
+
+选择 `code` 或 `both` 需要已组合的代码运行时（`ctx.codeRuntime`），且其语言有已注册的 SDK 渲染器——TypeScript 运行时经 [`dsh-code-runtime-worker-thread`](../../code-runtime/code-runtime-worker-thread/README.zh.md) 交付，TypeScript 与 Python 的 SDK 渲染器都内置在 `dsh-tools` 中。针对未组装此类运行时的部署选择 code 类模式的 preset 会拒绝挂载并点名这一行，使失败落在操作者可以行动的地方，而不是落在会话的第一次请求上。
+
+### 每个 agent 只声明一次呈现方式
 
 一个 agent 只声明一次呈现方式。同一份组装里的第二次声明会被拒绝而不是合并：对「模型看到哪种形态」给出两个答案是矛盾，不是覆盖。

+### 设计理念
+
+工具注册表搬不进 preset：它的消费者全在宿主平面——agent loop 读它的调度器，API proxy 读它的 presenter，每个工具插件都往里注册——而一个服务只有在所有消费者一起下沉时才能下沉。preset 能拥有的是这份注册表的呈现方式。`ctx.tools.presentAs()` 为挂载作用域声明它，而挂载作用域就是 preset 的常驻挂载，因此该声明覆盖每个加入该 preset 的 agent，一个 Code Mode preset 可以与多个 native 会话同进程并存。每个组合一行，而不是每个会话一行。

-间接生效，取决于它在 `dsh-tools` 中选择的投影：`code` 呈现 `run_code`、一份生成的 SDK 段，以及「只有 `run_code` 可被直接调用」这条规则，`native` 呈现每个工具的 schema。该选择同时决定了**什么可以执行**：在 `code` 下，注册表会把模型直呼其他任何工具名解析为 `UNKNOWN_TOOL`，因此这一行正是让「通告面」与「可调用面」对每个被它覆盖的 agent 保持一致的东西（[执行器塌缩 note](../../../.agents/notes/implemented/bug-fix/2026-08-07-code-mode-executor-collapse.zh.md)）。

-Agent interface, registry, process-local initiator scope, and `agent/*` event vocabulary. Every plugin (UI, hooks, orchestrators) programs against the `Agent` handle defined here — it has zero loop dependency, so the loop is swappable.
+## Summary
 
-The optional `@deepseek-ai/dsh-agent/invariant` companion registers this package's agent-status transition checks with `ctx.invariants`. The root agent service does not load diagnostics implicitly.
+With `dsh-agent` you can create or resume an agent, send a follow-up prompt, steer the current step, inject model-facing context, cancel an activity, and wait until the agent is idle — all through the `Agent` handle every plugin programs against and the live registry (`ctx.agents`) that tracks running agents. The package also carries the process-local initiator scope, which attributes asynchronous work to the agent that started it, and declares the `agent/*` event vocabulary plugins use to observe or intercept work in flight. It has zero loop dependency: concrete creation and driving live in `dsh-agent-loop`, which registers its factory here, so the driver stays swappable. Choose this package when you build UI, hooks, orchestrators, or extension plugins that touch live agents; the interface itself runs no model calls.

-### Public API
+-----
 
-The scoped-registration surface: `Agent.ctx` is the agent's scope context (`dsh-scope`, key = the agent) — register tools/sections/variables/listeners through it for that agent alone, all unwound on disposal. `agentEvents(ctx, agent)` is the fused dispatcher for ordinary agent-subject operations (carrier + injected subject in one move); its notification mode invokes every listener and contains both synchronous throws and returned-promise rejections. The registry lifecycle pair reuses one stable routing carrier. `assembleContextFor(agent)` builds the per-agent assembly context (`agent` + `scope` together). `installModelSelection(agentCtx, selection)` snapshots a mutable provider/model/reasoning-effort selection during prompt assembly, applies its provider and model to prompt variables, and applies the complete selection to request routing for one step; an absent selected effort clears an inherited effort so adapter/provider defaults apply. `CreateAgentOptions.setup(agentCtx)` and `ResumeAgentOptions.setup(agentCtx)` compose a fresh or resumed agent's scoped world while both objects remain unpublished. Setup is trusted, composition-only same-process code: drive the agent only after creation resolves.
+<a id="use-this-package"></a>
+## Use this package
 
-`AgentOptions` supplies the initial provider/model route, optional adapter-owned `reasoningEffort`, and optional positive `maxTokens` output cap. The concrete loop validates exact-model reasoning support, resolves adapter defaults, records the effective values in the request header, and applies them to each conversation-model request; an explicit Agent option wins, while omission leaves the adapter or provider route default in control.
+Mount `dsh-agent` wherever live agents exist: it provides `ctx.agents` and the `Agent` handle that plugins, UI, hooks, and orchestrators work against. The service is inert until a driver registers a factory — the shipped driver is `dsh-agent-loop`, so the smallest useful composition loads both.
 
-- `ctx.agents.register(agent: Agent): () => void` — record an **already-constructed** agent. Disposed with the calling fiber.
-- Advanced ordered lifecycle: `enter(agent, owner): () => void` enforces `agent.id === agent.session.id`, performs the authoritative ID collision check, and inserts without announcing; `owner` explicitly records the live creator-agent relation (or `undefined` for a root), independently of durable session lineage. `announce(agent)` emits `agent/created` exactly once. A detach requested synchronously by a creation listener is deferred until that dispatch unwinds, and every detach checks the captured entry object, so a stale capability cannot delete a later same-ID replacement. The async factory uses this split; ordinary plugins use `register()`.
-- `ctx.agents.get(id: SessionId): Agent | undefined`
-- `ctx.agents.isOwnedBy(id: SessionId, owner: Agent): boolean` — whether the exact live entry was created through that parent agent's scoped context; runtime ownership is independent of durable session lineage.
-- `ctx.agents.list(): Agent[]`
-- `ctx.agents.roots(): Agent[]` — live agents created without an owning agent context; a resumed lineage-bearing session can still be a runtime root.
+### Create or resume an agent
 
-#### Initiating Agent scope
+`ctx.agents.create()` builds a fresh agent and session under one identity; `ctx.agents.resume()` loads a persisted session and rebuilds the agent on it. Both delegate to the registered factory and return an `AgentHandle` — the only object that can tear that agent down. `get(id)`, `list()`, and `roots()` find live agents, and `isOwnedBy(id, owner)` tells whether one agent was created through another's scoped context.
 
-`AgentLoop` runs each concrete driver's complete lifetime inside an initiator boundary. Concurrent drivers remain isolated: a child driver's continuations carry the child, while the parent continuation regains the parent as soon as `withInitiator()` returns; drain tracking continues until the child driver's Promise settles. Creation, persistence load, and unpublished setup remain outside the child's boundary, so setup initiated by a parent inherits the parent while `agentCtx.agent` identifies the child explicitly.
+```text
+const handle = await ctx.agents.create({
+  sessionId,
+  agentOptions: { provider: 'deepseek', model: 'deepseek-chat' },
+})
+// later:
+await handle.dispose()   // stops the loop, unregisters, removes the session, unwinds the scope
+```
 
-- `ctx.agents.currentInitiator(): Agent | undefined` — read the inherited initiator without requiring one.
-- `ctx.agents.requireInitiator(): Agent` — read it or throw `no initiating agent is active`.
-- `ctx.agents.withInitiator(agent, operation)` — run with one exact Agent and preserve the operation's exact synchronous value or Promise.
-- `ctx.agents.withoutInitiator(operation)` — hide an inherited initiator for unrelated process-local work.
+`AgentOptions` supplies the initial provider/model route, optional adapter-owned `reasoningEffort`, and optional positive `maxTokens` output cap. The loop validates exact-model reasoning support, resolves adapter defaults, records the effective values in the request header, and applies them to each conversation request. An optional `setup(agentCtx)` callback composes the agent's scoped world before it is published — scoped tools, prompt sections, and listeners exist before any creation announcement. Setup is composition-only: drive the agent only after creation resolves.
 
-The scope carries the `Agent` itself and is process-local. Ambient presence is neither liveness proof nor authorization; explicit Agent fields remain authoritative at service, worker, process, persistence, and wire boundaries. Teardown rejects new boundaries, lets injected dependents and returned-Promise boundaries drain, then disables the underlying `AsyncLocalStorage`; unreturned work remains owned by the subsystem that detached it. If a boundary's inherited async chain starts an owning Cordis fiber's unload, that nested boundary chain is released from the drain so the unload cannot wait on itself; its continuations observe the disposed service after teardown. The [initiator-scope decision](../../../.agents/notes/implemented/architecture/2026-07-15-agent-initiator-scope.md) owns the detailed boundary and teardown contract.
+### Drive an agent's conversation
 
-#### Factory API (creation)
+The handle's methods route identified user-role messages into the agent's inbox. `followup()` queues an ordinary next-turn prompt and wakes the driver; `steer()` submits next-step input and wakes it; `inject()` adds model-facing context without waking the driver, so it lands in the next admitted step. `cancel(cause)` aborts the active activity and, unless `keepInbox` is set, clears pending work; `whenIdle()` resolves after the whole agent reaches quiescence.
 
-Agent *creation* is provided by the plugin implementing `AgentFactory` (`dsh-agent-loop`), registered via `setFactory`. This keeps creation on the `dsh-agent` interface so consumers (UI, the ACP bridge) program against `ctx.agents` without depending on the concrete loop package. The registry canonicalizes an already traced Service to its concrete target and re-traces each call through the caller's context; this avoids nested Cordis shadows while passing an explicit caller-bound `ownerCtx` to plain factories.
+```text
+handle.agent.followup({
+  content: [{ type: 'text', text: 'Summarize this workspace.' }],
+  source: { kind: 'user' },
+})
+handle.agent.steer({
+  content: [{ type: 'text', text: 'Focus on the tests.' }],
+  source: { kind: 'plugin', plugin: 'my-plugin' },
+})
+await handle.agent.whenIdle()
+```
 
-- `ctx.agents.setFactory(factory: AgentFactory): () => void` — register the creation factory (the loop calls this on construction). Throws on a second factory; the slot clears on dispose.
-- `ctx.agents.create(options: CreateAgentOptions): Promise<AgentHandle>` — create a session and agent, await optional setup while unpublished, then publish through final `SessionStore.enter()` and `AgentRegistry.enter()` checks. Concurrent same-ID creation is unsupported: more than one operation may prepare, but only one can enter; every loser rolls its private scope/session/driver back. An optional creation-only `signal` cancels unpublished setup and is detached before the handle is returned; later cancellation uses `handle.dispose()` or `agent.cancel()`. Publication is rollback-covered and every delivered creation edge is paired during rollback. Rejects if no factory is registered.
-- `ctx.agents.resume(options: ResumeAgentOptions): Promise<AgentHandle>` — load a persisted session ([session persistence](../../../.agents/notes/implemented/architecture/2026-06-14-session-persistence.md)), mint a fresh unpublished agent scope, await optional setup, and use the same final-entry publication sequence. Its optional `signal` is likewise creation-only. Rejects if no factory is registered or session persistence is unconfigured.
+### Scope registrations to one agent
 
-`AgentHandle = { agent: Agent; dispose(): Promise<void> }`. The disposer is a **consumer capability** — no observer holding the bare registry entry can tear the agent down. The caller fiber and the registered factory provider are structural co-owners: caller unload enforces structured ownership, while factory unload must stop old instances because their scoped dependency surface belongs to that provider. `dispose()` from any owner reaches one memoized quiescence boundary: it stops the loop, awaits its exit, unregisters the agent, removes its session from the store, and finally unwinds its scoped world. `ctx.agents.get(id)` still returns a bare `Agent`; the ACP bridge and in-process subagent backends hold consumer handles, while config-created agents are already owned by the loop fiber.
+`Agent.ctx` is the agent's scoped context: registrations made through it (tools, prompt sections, variables, event listeners, restrictions) apply to that agent alone and unwind on disposal. The same mechanism is what agent presets use to give one session a different capability set without affecting its neighbors.
 
-### Live events
+### Intercept or observe work in flight
 
-`dsh-agent` declares the live `agent/*` coordination vocabulary so plugins do not depend on the concrete loop. Exact signatures, dispatch modes, scope-filtering rules, and payload contracts live in the generated region of [core.md](../../../docs/subsystems/core.md#cordis-surface); the [architecture turn flow](../../../docs/architecture.md#turn-flow) shows their order relative to durable session events.
+The `agent/*` events let plugins act on live work without depending on the loop package. `agent/pre-step` can reject a proposed step or replace the messages entering it; `agent/request-error` lets a listener retry a failed model request; `agent/turn-stopping` runs before an otherwise completed turn closes and can steer to keep it open. `agent/status`, `agent/created`, and `agent/disposed` drive UI and coordination state, and the per-message `agent/inbox/*` notifications keep inbox projections in sync. Exact signatures, dispatch modes, and payload contracts live in the generated region of the [core subsystem page](../../../docs/subsystems/core.md#cordis-surface).
 
-The lifecycle edges have two important local caveats. `agent/created` runs after scoped setup and after both session and agent registry entries exist. Setup is trusted composition-only code; the immediately following non-vetoing `agent/session-start` notification is the first supported startup injection point. `agent/disposed` always means the exact agent has left the registry. AgentLoop emits it after its driver is quiescent, while ordered teardown may still be detaching the session and unwinding the scope; custom agents registered directly own any stronger driver-ordering contract themselves.
+-----
 
-Most interception points are cooperative waterfalls. `agent/pre-step` receives a payload carrying the subject `agent`, the exclusive claimed `UserMessage[]`, and the proposed `turn`, `step`, and cancellation `signal`; its batch may be empty when tools already require another request. Agent-scoped turn extension points carry their explicit `AbortSignal` in the payload; the remaining turn-scoped extension points receive it through their request value. Listeners may cooperate with a signal but must not retain it as authority over another turn. `agent/request-error` is the failed-model-request recovery waterfall: it receives request coordinates, normalized failure facts, the serving registration's retry policy when available, and the signal. A listener returns `{ kind: 'retry' }` without calling `next()` when it owns recovery. `agent/turn-stopping` runs before an otherwise completed turn closes. The [explicit-cancellation decision](../../../.agents/notes/implemented/architecture/2026-07-16-explicit-turn-cancellation.md) owns signal lifetime; the [agent-scope runtime-design Agent Note](../../../.agents/notes/implemented/architecture/2026-07-12-agent-scope-runtime-design.md#three-execution-boundaries-are-deliberately-one-way) owns scoped dispatch and terminal settlement.
+<a id="understand-the-implementation"></a>
+## Understand the implementation
 
-`PreStepDecision` is either `{ kind: 'reject' }` or `{ kind: 'enter', messages, startsRequestSeries? }`. The enter branch is the complete identified, frozen batch for the proposed step. `startsRequestSeries: true` declares that this admitted batch begins a distinct model-message series; ordinary follow-ups leave it absent. A listener that wraps downstream entry preserves both that declaration and the batch unless it intentionally replaces either one; additions follow the waterfall's natural return order. Claiming already removed the offered messages from the inbox, so rejection does not retain them. Messages inserted after the claim remain pending for a later boundary.
+<details>
+<summary>Implementation internals — click to expand</summary>
 
-Inbox live notifications are deliberately per-message and minimal: `agent/inbox/inserted { message }`, `agent/inbox/claimed { message, turn }`, and `agent/inbox/discarded { message }`. They complement the durable `agent/inbox/spliced` projection without adding another lifecycle envelope.
+This section explains how the package realizes the behavior above; the observable contract is covered in [Use this package](#use-this-package).
 
-Turn and step boundaries and the model token stream are durable `session/event` facts rather than mirrored `agent/*` notifications. Consumers read `turn/*`, `step/*`, and `assistant/chunk` from the session feed; tool policy and outcome observation belong to the complete pipeline documented by [`dsh-tools`](../tools/README.md).
+### Design concept
 
-`foldConsumedWork(events)` reads that feed back for the one question the turn sequence cannot answer alone: what became of the work a log consumed. It returns the latest `turn/end` that accounts for consumed work — a turn that entered a model step, or one that claimed inbox input and then failed, was stopped, or was rejected before reaching one — plus whether accepted work was later cancelled out of the inbox unrun. Both facts come from the log, so a cancellation reads the same whichever owner issued it. A no-step turn that took nothing, or emptied its claim and completed, describes no work and is skipped; a `blocked` end over claimed input is an account, because rejection discarded that input.
+The package is built on one separation: the public `Agent` surface and registry live here, while construction and driving live in the loop package behind a registered factory. Consumers therefore depend on `dsh-agent` and never on `dsh-agent-loop`, keeping the driver swappable. The second idea is the initiator scope: an `AsyncLocalStorage` chain that carries the exact live `Agent` through the asynchronous driver work it starts, so helpers below a driver can attribute their work without forwarding the agent through every call.
 
-### Agent interface (`types.ts`)
+### Step admission
 
-The handle every plugin programs against:
+`PreStepDecision` is either `{ kind: 'reject' }` or `{ kind: 'enter', messages, startsRequestSeries? }`. The enter branch contains the complete identified, frozen message batch. `startsRequestSeries: true` declares a distinct model-message series; a wrapping listener preserves that declaration and the batch unless it intentionally replaces either one. Claiming removes offered messages from the inbox, while messages inserted after the claim remain pending for a later boundary.
 
-- `agent.inbox` — the agent-owned projection of durable `agent/inbox/spliced` events. `nextTurn` and `nextStep` expose pending `UserMessage` values. `append`, `prepend`, `replace`, `remove`, `clear`, `splice`, and `claim` mutate them; `replace(messageId, newMessage)` and `remove(messageId)` locate the pending message across both lists. Replacement may change identity and publishes the old message as discarded followed by the new message as inserted. Ordinary removals and `clear()` are durable cancellations and emit `agent/inbox/discarded`. `claim(target)` removes the next proposed batch with pure deletion splices; the loop then emits `agent/inbox/claimed`. `MessageId` is the only occurrence identity and must remain unique while pending.
-- `agent.followup(message)` — queue an ordinary `next-turn` message and wake the driver. It returns no completion handle; the message id identifies inbox insertion, claim, and discard facts, not a later output or `turn/end`.
-- `agent.steer(message)` — queue waking `next-step` input. An idle agent starts a turn synchronously; a running driver consumes later steering at its next step boundary.
-- `agent.inject(message)` — queue non-waking `next-step` context. A running driver claims it at the nearest later pre-step boundary; an idle driver leaves it pending until `followup()` or `steer()` wakes the driver. It may miss a request whose pre-step already claimed its batch.
-- `agent.cancel(cause, options?)` — cancel the active driver and, unless `options.keepInbox`, durably cancel all pending inbox work. Idle cancellation is a no-op.
-- `agent.whenIdle()` — observe whole-agent quiescence, including replacement work scheduled before the current driver retires. It does not settle any particular message.
-- `agent.session`, `agent.status`, `agent.options`, `agent.id`, `agent.ctx`
+### Source map
 
-`running` describes a driver-wide drain interval, not proof that a turn is still open; it can cover turn close, the durability checkpoint, and consecutive queued turns. Only a caller that owns a complete interval may summarize it as a run result ([decision](../../../.agents/notes/implemented/architecture/2026-07-30-followup-enqueue-and-owned-runs.md)).

-### Extension points
+### Registry and lifecycle
 
-- Agent creation: `AgentLoop.create()` is the concrete config-path implementation (in `dsh-agent-loop`), while programmatic consumers create/resume owned agents through `ctx.agents.create()` / `ctx.agents.resume()`. Replace the loop by implementing `Agent` and registering via `ctx.agents.register()`.
-- Event listeners: all `agent/*` events are declared here — no dependency on the loop package needed.
-- Subagent delegation is not an `Agent` method; providers create or drive ordinary handles through the factory API, so delegation transports stay outside the core agent interface.
+`AgentRegistry` keeps one entry per live agent with its carrier and creator relation. `register()` records an already-constructed agent; the async factory uses the split `enter()`/`announce()` pair so setup and publication stay rollback-covered. A detach requested during a creation dispatch waits for that dispatch to unwind, and each detach is bound to the exact entry, so a stale disposer cannot remove a later same-id replacement. Teardown order is stop-and-drain the loop, unwind the scope, detach the agent, detach the session; the id becomes reusable after private cleanup.
 
+### Initiator scope
+
+Each driver runs its complete lifetime inside `ctx.agents.withInitiator(agent, ...)`, so inherited async chains observe that agent; `withoutInitiator()` hides it for unrelated process-local work such as shared timers. The boundary is process-local attribution only — ambient presence is neither liveness proof nor authorization, and explicit identity stays authoritative at worker, process, persistence, and wire boundaries. Teardown rejects new boundaries, lets returned-Promise boundaries drain, then disables the underlying storage. The [initiator-scope decision](../../../.agents/notes/implemented/architecture/2026-07-15-agent-initiator-scope.md) owns the detailed contract.
+
+### Ownership invariants
+
+The `AgentHandle` disposer is a capability: among consumers, only its holder can tear the agent down. The registered factory provider is a structural co-owner, because scoped agents depend on that provider's service API; provider unload stops and drains every live handle it made. `ctx.agents.get(id)` still returns a bare `Agent` — the handle is exposed only to the consumer that created it.

-### 公开 API
+-----
 
-带作用域的注册接口：`Agent.ctx` 是 agent 的作用域上下文（`dsh-scope`，键 = 该 agent）。通过它注册工具／段／变量／监听器，只对该 agent 生效，并在 dispose（资源释放）时全部撤销。`agentEvents(ctx, agent)` 是普通 agent 主体操作的融合分发器（一次完成载体 + 注入主体）；其通知 mode 会调用每个监听器，并同时收容同步抛出和返回 Promise 的拒绝。注册表生命周期对复用一个稳定路由载体。`assembleContextFor(agent)` 构建按 agent 的组装上下文（同时包含 `agent` + `scope`）。`installAgentLlmTarget(agentCtx, target)` 在提示词组装期间快照可变的提供方／模型／推理（reasoning）强度选择，将路由应用到提示词变量，并将完整目标应用到一个步骤的请求路由；如果没有选定推理强度，则会清除继承的推理强度，使该目标使用适配器／提供方默认值。`CreateAgentOptions.setup(agentCtx)` 和 `ResumeAgentOptions.setup(agentCtx)` 在新建或恢复的 agent 尚未发布时，组合其带作用域的世界。Setup 是受信任、仅用于组合的同进程代码：只有创建完成后才能驱动 agent。
+<a id="use-this-package"></a>
+## 使用本包
 
-`AgentOptions` 提供初始的提供方／模型路由、可选且由适配器定义的 `reasoningEffort`，以及可选的正数 `maxTokens` 输出上限。具体循环会校验确切模型支持的推理强度、解析适配器默认值，把生效值记录到请求 header，并应用到每次对话模型请求；显式 Agent 选项优先，省略时由适配器或提供方路由默认值控制。
+在存在实时 agent 的任何地方挂载 `dsh-agent`：它提供 `ctx.agents` 以及插件、UI、钩子和编排器所面向编程的 `Agent` 句柄。在没有驱动器注册工厂之前，该服务保持惰性——随附驱动器是 `dsh-agent-loop`，因此最小的可用组合需要同时加载两者。
 
-- `ctx.agents.register(agent: Agent): () => void`：记录一个 **已经构造完成** 的 agent。随调用 fiber dispose。
-- 高级有序生命周期：`enter(agent, owner): () => void` 强制 `agent.id === agent.session.id`，执行权威 ID 冲突检查，并在不通知的情况下插入；`owner` 显式记录实时创建方 agent 关系（根 agent 为 `undefined`），与持久会话谱系无关。`announce(agent)` 恰好发出一次 `agent/created`。创建监听器同步请求的 detach 会延后到该次分发结束；每次 detach 都会检查捕获的条目对象，因此陈旧能力无法删除后续使用同一 ID 的替代项。异步工厂使用这一拆分；普通插件使用 `register()`。
-- `ctx.agents.get(id: SessionId): Agent | undefined`
-- `ctx.agents.isOwnedBy(id: SessionId, owner: Agent): boolean`：该确切实时条目是否通过父 agent 的作用域上下文创建；运行时所有权与持久会话谱系无关。
-- `ctx.agents.list(): Agent[]`
-- `ctx.agents.roots(): Agent[]`：在没有所属 agent 上下文的情况下创建的实时 agent；带谱系的恢复会话仍可能是运行时根。
+### 创建或恢复 agent
 
-<a id="initiating-agent-scope"></a>
+`ctx.agents.create()` 在一个身份下构建全新 agent 与会话；`ctx.agents.resume()` 加载持久化会话并在此基础上重建 agent。两者都委托给已注册工厂，并返回 `AgentHandle`——唯一能拆除该 agent 的对象。`get(id)`、`list()` 与 `roots()` 用于查找实时 agent；`isOwnedBy(id, owner)` 用于判断一个 agent 是否通过另一个 agent 的作用域上下文创建。
 
-#### 发起方 Agent 作用域
+```text
+const handle = await ctx.agents.create({
+  sessionId,
+  agentOptions: { provider: 'deepseek', model: 'deepseek-chat' },
+})
+// later:
+await handle.dispose()   // stops the loop, unregisters, removes the session, unwinds the scope
+```
 
-`AgentLoop` 在发起方边界内运行每个具体驱动器的完整生命周期。并发驱动器彼此隔离：子驱动器的 continuation 携带子 agent，而 `withInitiator()` 返回后，父 continuation 立即重新取得父 agent；drain 跟踪持续到子驱动器的 Promise 结算。创建、持久化加载和未发布 setup 位于子边界之外，因此由父 agent 发起的 setup 会继承父 agent，而 `agentCtx.agent` 显式标识子 agent。
+`AgentOptions` 提供初始 provider/model 路由、可选的适配器所有 `reasoningEffort`，以及可选的正数 `maxTokens` 输出上限。循环会校验确切模型的推理支持、解析适配器默认值、把有效值记录在请求头中，并将它们应用到每个对话请求。可选的 `setup(agentCtx)` 回调会在 agent 发布之前组合其作用域世界——作用域工具、提示词段与监听器在任何创建公告之前就已存在。Setup 只做组合：创建完成后才能驱动 agent。
 
-- `ctx.agents.currentInitiator(): Agent | undefined`：读取继承的发起方，不要求其存在。
-- `ctx.agents.requireInitiator(): Agent`：读取发起方，缺席时抛出 `no initiating agent is active`。
-- `ctx.agents.withInitiator(agent, operation)`：使用一个确切 Agent 运行，并保留操作的确切同步值或 Promise。
-- `ctx.agents.withoutInitiator(operation)`：对无关的进程本地工作隐藏继承的发起方。
+### 驱动 agent 的对话
 
-该作用域携带 `Agent` 本身，并且只在进程内有效。环境中的身份既不是存活证明，也不是授权；在服务、worker、进程、持久化和 wire 边界，显式 Agent 字段仍是权威来源。Teardown 会拒绝新边界，允许注入的依赖方和返回 Promise 的边界 drain，然后禁用底层 `AsyncLocalStorage`；未返回的工作仍归将其分离的子系统所有。如果某个边界继承的异步链开始卸载一个拥有它的 Cordis fiber，该嵌套边界链会从 drain 中释放，使卸载不会等待自身；其 continuation 会在 teardown 后观察到已 dispose 的服务。详细边界与 teardown 约定由[发起方作用域决策](../../../.agents/notes/implemented/architecture/2026-07-15-agent-initiator-scope.zh.md)拥有。
+句柄的方法把带标识的 user 角色消息路由进 agent 的收件箱。`followup()` 排队一条普通的下一个轮次提示词并唤醒驱动器；`steer()` 提交下一步输入并唤醒它；`inject()` 添加面向模型的上下文但不唤醒驱动器，因此它落在下一个被接纳的步骤中。`cancel(cause)` 中止当前活动，并在未设置 `keepInbox` 时清除待处理工作；`whenIdle()` 在整个 agent 达到完全停稳后兑现。
 
-#### 工厂 API（创建）
+```text
+handle.agent.followup({
+  content: [{ type: 'text', text: 'Summarize this workspace.' }],
+  source: { kind: 'user' },
+})
+handle.agent.steer({
+  content: [{ type: 'text', text: 'Focus on the tests.' }],
+  source: { kind: 'plugin', plugin: 'my-plugin' },
+})
+await handle.agent.whenIdle()
+```
 
-Agent *创建* 由实现 `AgentFactory` 的插件（`dsh-agent-loop`）提供，并通过 `setFactory` 注册。这样，创建功能留在 `dsh-agent` 接口上，消费方（UI、ACP（Agent Client Protocol）桥接层）可以面向 `ctx.agents` 编程，而不依赖具体循环包。注册表会把已经 traced 的 Service 规范化为具体目标，并通过调用方上下文重新 trace 每次调用；这既避免嵌套 Cordis shadow，也会把显式、绑定调用方的 `ownerCtx` 传给普通工厂。
+### 将注册限定到单个 agent
 
-- `ctx.agents.setFactory(factory: AgentFactory): () => void`：注册创建工厂（循环在构造时调用）。第二个工厂会导致抛出；dispose 时清空槽位。
-- `ctx.agents.create(options: CreateAgentOptions): Promise<AgentHandle>`：创建会话和 agent，在不发布的情况下等待可选 setup，然后通过最终的 `SessionStore.enter()` 与 `AgentRegistry.enter()` 检查发布。不支持并发创建同一 ID：多个操作可以进行准备，但只有一个能进入；每个失败方都会回滚其私有作用域／会话／驱动器。可选且只用于创建的 `signal` 会取消未发布的 setup，并在返回 handle 前分离；之后的取消使用 `handle.dispose()` 或 `agent.cancel()`。发布包含在回滚范围内，回滚期间每条已交付创建边都会成对处理。未注册工厂时拒绝。
-- `ctx.agents.resume(options: ResumeAgentOptions): Promise<AgentHandle>`：加载持久化会话（[会话持久化](../../../.agents/notes/implemented/architecture/2026-06-14-session-persistence.zh.md)），创建新的未发布 agent 作用域，等待可选 setup，并使用相同的最终进入发布序列。其可选 `signal` 同样只用于创建。未注册工厂或未配置会话持久化时拒绝。
+`Agent.ctx` 是该 agent 的作用域上下文：通过它进行的注册（工具、提示词段、变量、事件监听器、限制）只对该 agent 生效，并在 dispose（资源释放）时全部撤销。同一机制也是 agent preset 用来让一个会话获得不同能力集、同时不影响其邻居的方式。
 
-`AgentHandle = { agent: Agent; dispose(): Promise<void> }`。Disposer 是一项 **消费方能力**；仅持有裸注册表条目的观察方不能 teardown agent。调用方 fiber 和已注册工厂提供方是结构化共同拥有者：调用方卸载会强制结构化所有权，而工厂卸载必须停止旧实例，因为它们的作用域依赖范围属于该提供方。任意拥有者调用 `dispose()` 都会到达同一个记忆化完全停稳边界：它停止循环，等待循环退出，注销 agent，从存储中移除其会话，最后撤销其作用域世界。`ctx.agents.get(id)` 仍返回裸 `Agent`；ACP 桥接层与进程内 subagent 后端持有消费方 handle，而配置创建的 agent 已由循环 fiber 拥有。
+### 拦截或观察进行中的工作
 
-### 实时事件
+`agent/*` 事件让插件无需依赖循环包即可作用于实时工作。`agent/pre-step` 可以拒绝拟进入的步骤或替换进入它的消息；`agent/request-error` 让监听器重试失败的模型请求；`agent/turn-stopping` 在本可完成的轮次关闭前运行，并可通过 steer 使其保持打开。`agent/status`、`agent/created` 与 `agent/disposed` 驱动 UI 与协调状态，逐消息的 `agent/inbox/*` 通知则让收件箱投影保持同步。确切签名、分发 mode 与 payload 约定见 [core 子系统页](../../../docs/subsystems/core.zh.md#cordis-surface) 的生成区块。
 
-`dsh-agent` 声明实时 `agent/*` 协调词汇，使插件不必依赖具体循环。确切签名、分发 mode、作用域筛选规则与 payload 约定位于 [core.md](../../../docs/subsystems/core.zh.md#cordis-surface) 的生成区块；[架构轮次流](../../../docs/architecture.zh.md#turn-flow) 展示它们与持久会话事件的相对顺序。
+-----
 
-生命周期边有两个重要的本地注意事项。`agent/created` 在作用域 setup 之后、会话与 agent 注册表条目都存在之后运行。Setup 是受信任、仅用于组合的代码；紧随其后且不可 veto 的 `agent/session-start` 通知是第一个受支持的启动注入点。`agent/disposed` 始终表示确切 agent 已离开注册表。AgentLoop 在其驱动器完全停稳后发出该事件，而有序 teardown 此时可能仍在分离会话并撤销作用域；直接注册的自定义 agent 自行拥有任何更强的驱动器顺序约定。

-大多数拦截点都是协作式 waterfall（瀑布式事件）。`agent/pre-step` 接收一个 payload，携带主体 `agent`、独占的已领取 `UserMessage[]` 以及拟进入的 `turn`、`step` 与取消 `signal`；当工具已经要求继续请求时，该批次可以为空。agent 作用域轮次扩展点在 payload 中携带显式 `AbortSignal`；其余轮次作用域扩展点通过其请求值接收它。监听器可以配合信号，但不得将它保留为控制另一轮次的权限。`agent/request-error` 是失败模型请求的恢复 waterfall：它接收请求坐标、规范化失败事实、可用时提供服务的注册项重试策略以及信号。拥有恢复权的监听器返回 `{ kind: 'retry' }` 且不调用 `next()`。`agent/turn-stopping` 在本可完成的轮次关闭前运行。信号生命周期由[显式取消决策](../../../.agents/notes/implemented/architecture/2026-07-16-explicit-turn-cancellation.zh.md)拥有；作用域分发与终止结算由 [agent 作用域 runtime 设计 Agent Note](../../../.agents/notes/implemented/architecture/2026-07-12-agent-scope-runtime-design.zh.md#three-execution-boundaries-are-deliberately-one-way)拥有。

-`PreStepDecision` 要么是 `{ kind: 'reject' }`，要么是 `{ kind: 'enter', messages, startsRequestSeries? }`。enter 分支是拟进入步骤的完整、带标识且冻结的批次。`startsRequestSeries: true` 声明该接纳批次会开启一个独立的模型消息序列；普通 follow-up 不设置它。包装下游 enter 的监听器会同时保留该声明和消息批次，除非有意替换其中一项；新增消息遵循 waterfall 的自然返回顺序。领取操作已经把候选消息从 inbox 删除，因此 reject 不会保留它们；领取后插入的消息仍等待后续边界。
+本节解释该包如何实现上述行为；可观察约定已在[使用本包](#use-this-package)中完整说明。
 
-inbox 的实时通知刻意采用逐消息的最小载荷：`agent/inbox/inserted { message }`、`agent/inbox/claimed { message, turn }` 与 `agent/inbox/discarded { message }`。它们补充持久 `agent/inbox/spliced` 投影，但不引入另一层生命周期封套。
+### 设计理念
 
-轮次和步骤边界以及模型 token 流是持久 `session/event` 事实，而不是镜像的 `agent/*` 通知。消费方从会话事件流读取 `turn/*`、`step/*` 和 `assistant/chunk`；工具策略与结果观测属于 [`dsh-tools`](../tools/README.zh.md) 记录的完整流水线。
+该包建立在一个分离之上：公开的 `Agent` 表面与注册表在此处，而构造与驱动位于循环包中、注册工厂之后。消费方因此依赖 `dsh-agent` 而从不依赖 `dsh-agent-loop`，驱动器保持可替换。第二个理念是发起方作用域：一条 `AsyncLocalStorage` 链把确切的实时 `Agent` 携带经过它启动的异步驱动器工作，使驱动器之下的辅助函数无需逐调用转发 agent 即可归因自己的工作。
 
-`foldConsumedWork(events)` 把这条事件流读回来，回答仅凭轮次序列无法回答的那个问题：一份日志消费掉的工作最终怎样了。它返回能够为已消费工作作出交代的最新 `turn/end`——即进入过模型 step 的轮次，或者认领了 inbox 输入、但在进入 step 之前失败、被停下或被拒绝的轮次——并额外给出「已接受的工作此后是否被从 inbox 中取消且从未运行」。两项事实都来自日志，因此无论由哪个所有者发起取消，读出来都一样。没有取走任何输入、或认领批次被改写清空后正常结束的无 step 轮次不描述工作，会被跳过；认领过输入、以 `blocked` 结束的轮次则是一份交代，因为拒绝把这些输入一并丢弃了。
+### 步骤准入
 
-### Agent 接口（`types.ts`）
+`PreStepDecision` 要么是 `{ kind: 'reject' }`，要么是 `{ kind: 'enter', messages, startsRequestSeries? }`。enter 分支包含完整、带标识且冻结的消息批次。`startsRequestSeries: true` 声明一个独立的模型消息序列；包装下游 enter 的监听器会保留该声明与批次，除非有意替换其中一项。领取会从 inbox 移除候选消息，领取后插入的消息则等待后续边界。
 
-每个插件面向的 handle：
+### 源码地图
 
-- `agent.inbox`：agent 所拥有的持久 `agent/inbox/spliced` 事件投影。`nextTurn` 与 `nextStep` 暴露待处理的 `UserMessage` 值。`append`、`prepend`、`replace`、`remove`、`clear`、`splice` 与 `claim` 用于变更队列；`replace(messageId, newMessage)` 与 `remove(messageId)` 通过 `MessageId` 跨两份列表定位待处理消息。替换可以改变标识，并先将旧消息作为 discarded 发布，再将新消息作为 inserted 发布。普通删除和 `clear()` 都是持久取消，并发出 `agent/inbox/discarded`。`claim(target)` 通过纯删除 splice 移除下一个候选批次，随后由循环发出 `agent/inbox/claimed`。`MessageId` 是唯一的入队项标识，在消息待处理期间必须保持唯一。
-- `agent.followup(message)`：将一条普通 `next-turn` 消息排队并唤醒驱动器。它不返回完成 handle；消息 id 标识 inbox 的插入、领取与丢弃事实，而不标识之后的输出或 `turn/end`。
-- `agent.steer(message)`：将会唤醒的 `next-step` steering（中途引导）输入排队。agent 空闲时会同步启动一个轮次；驱动器运行期间收到的后续 steering 会在下一个步骤边界被消费。
-- `agent.inject(message)`：将不会唤醒的 `next-step` 上下文排队。运行中的驱动器会在最近的后续 pre-step 边界领取它；idle 驱动器则会让它保持待处理，直至 `followup()` 或 `steer()` 唤醒驱动器。若某次请求的 pre-step 已经领取完批次，它可能赶不上该请求。
-- `agent.cancel(cause, options?)`：取消活跃驱动器，并在未设置 `options.keepInbox` 时持久取消全部待处理 inbox 工作。空闲取消是空操作。
-- `agent.whenIdle()`：观察整个 agent 达到完全停稳，包括当前驱动器退役前调度的替代工作。它不结算任何特定消息。

+### 注册表与生命周期
 
-### 扩展点
+`AgentRegistry` 为每个实时 agent 保留一个条目，含其载体与创建者关系。`register()` 记录一个已构造完成的 agent；异步工厂使用拆分的 `enter()`/`announce()` 对，使 setup 与发布始终处于回滚保护之下。创建分发期间请求的 detach 会等待该次分发退栈，且每次 detach 都绑定到确切条目，因此陈旧 disposer 无法移除之后出现的同 id 替代项。Teardown 顺序是停止并排空循环、撤销作用域、detach agent、detach 会话；私有清理完成后该 id 即可复用。
 
-- Agent 创建：`AgentLoop.create()` 是具体配置路径实现（位于 `dsh-agent-loop`），程序化消费方则通过 `ctx.agents.create()`/`ctx.agents.resume()` 创建或恢复有所有权的 agent。替换循环时，应实现 `Agent` 并通过 `ctx.agents.register()` 注册。
-- 事件监听器：全部 `agent/*` 事件都在此处声明，不需要依赖循环包。
-- subagent 委派不是 `Agent` 方法；提供方通过工厂 API 创建或驱动普通 handle，因此委派传输留在核心 agent 接口之外。
+### 发起方作用域
 
+每个驱动器在 `ctx.agents.withInitiator(agent, ...)` 内运行其完整生命周期，因此继承的异步链会观察到该 agent；`withoutInitiator()` 为共享定时器等无关的进程本地工作隐藏它。该边界只是进程本地归因——环境中的身份既不是存活证明，也不是授权，显式身份在 worker、进程、持久化与 wire 边界保持权威。Teardown 拒绝新边界，让返回 Promise 的边界排空，然后禁用底层存储。[发起方作用域决策](../../../.agents/notes/implemented/architecture/2026-07-15-agent-initiator-scope.zh.md) 拥有详细约定。
+
+### 所有权不变式
+
+`AgentHandle` disposer 是一项能力：在消费方中，只有其持有者能拆除该 agent。已注册的工厂提供方是结构化共同拥有者，因为作用域 agent 依赖该提供方的服务 API；提供方卸载会停止并排空它创建的每个实时句柄。`ctx.agents.get(id)` 仍返回裸 `Agent`——句柄只暴露给创建它的消费方。

-Scoped registration primitive. `createScope(ctx, key)` creates a tagged Cordis context whose backing fiber owns every registration made through it. `scopeOf(ctx)` reads the tag, and `scopeTarget(base, key)` routes scoped events to listeners with the same key while leaving unscoped listeners global. Keys form an optional parent chain (`bindScopeParent`): registration views inherit DOWN it — a child scope sees its ancestors' layers, nearest shadowing farthest — and event admission extends UP it — a listener tagged with an ancestor receives a descendant key's events, never the reverse. The agent loop creates one scope per live agent and an agent preset's standing mount is a parent scope over its agents, but the mechanism is key-agnostic so lower-level packages can use it without depending on either.
+## Summary
 
-## Public API
+The dependency-free `dsh-scope` library gives registrations a per-agent home. Mint a tagged context with `createScope(ctx, key)` and everything registered through it is visible in one scope, unwinding when that scope disposes; read a context's scope tag with `scopeOf(ctx)`; and route scope-filtered events with `scopeTarget(base, key)` to listeners with the same key while leaving untagged listeners global. Keys can form a parent chain: a child scope sees its ancestors' layers (nearest shadows farthest), and a listener tagged with an ancestor receives descendant events — never the reverse. It is key-agnostic: the agent loop uses one scope per live agent and an agent preset's standing mount is a parent scope over its agents, but lower-level packages can use it without depending on either. Choose it when you build a registry or event surface that must isolate contributions per agent or per group.
 
-- `createScope(ctx: Context, key: ScopeKey, options?): Scope` Mint a scope under `ctx`'s fiber. Usable synchronously (effect collection is uid-gated; service resolution falls through to the minting plugin's dependency surface). The typed, same-process key is trusted; an inactive minting context still fails through Cordis (`INACTIVE_EFFECT`). `options.parent` binds the enclosing scope via `bindScopeParent` before the scope is usable; the binding stays internal.
-- `bindScopeParent(key, parent): ScopeParentBinding` / `scopeParentOf(key)` / `scopeChainOf(key)` The parent relation behind both chain directions. Binding is once: a key that already has a parent throws, and only the returned binding's `rebind(parent)` may re-link it — the blank-session recompose operation, valid only while nothing produced under the old parent is retained (the holder's contract — this relation cannot see what a session logged). Both the bind and every rebind reject a link closing a cycle. `scopeChainOf` returns `[key, parent, …]` nearest-first.
-- `Scope.ctx` The tagged context: registrations through it are scope-visible AND scope-lifetime. Derived contexts (an `extend`, a fiber mounted under it) inherit the tag; nested scopes shadow (nearest tag wins).
-- `Scope.rawDispose` The EXACT Cordis disposer for the backing fiber — a composite (generator) effect yields THIS function to nest the scope's teardown at that yield position (Cordis dedupes nested effects by function identity; yielding a wrapper leaves the scope disposing as a concurrent sibling).
-- `Scope.dispose(): Promise<void>` Idempotent, shared quiescence boundary for every registration made through the scope. Racing/repeat calls await the same teardown, including when `rawDispose` invoked the underlying single-shot Cordis disposer first.
-- `scopeOf(ctx: Context): ScopeKey | undefined` The tag a context (or any context derived from it) carries; `undefined` = context-global.
-- `scopeTarget(base: T, key: ScopeKey | undefined): Scoped<T>` Build the opaque dispatch `thisArg` for a scope-filtered event. It composes `base`'s existing `Context.filter` with the scope predicate (untagged listener ⇒ admitted; tagged ⇒ admitted iff its tag is the key or an ancestor of it; `key === undefined` ⇒ untagged only). The carrier contains routing state only; the real subject is carried by the event arguments. `{ global: true }` listeners bypass filtering (Cordis semantics).
-- `Scoped<T>` The compile-time opaque carrier brand: scope-filtered events demand it as their `this` type, so dispatching with a bare subject is a compile error. The type parameter records the subject type but does not expose its properties.
-- `isScopeCarrier(value)` / `carrierKeyOf(value)` Runtime carrier marks, used by the dev invariants to assert every scope-filtered dispatch carries a carrier keyed to the subject its arguments name.
-- `ScopeLayer` Aggregate contract for one registry's complete global or exact-scope contribution; `isEmpty()` controls scoped-layer reclamation.
-- `ScopedLayers<L>` Own one eager global layer and lazy exact-scope layers. `peek()` never creates and stays chain-blind (a scope's OWN contributions — restrictions, guards — must not silently pick up an ancestor's), `chainLayers()` returns existing overlays farthest-ancestor-first, `merge()` materializes insertion-ordered named shadows along the chain, and `effect()` derives visibility and ownership from the same context while returning the exact Cordis disposer.
-- `NamedEntries<V>` Insertion-ordered named storage with caller-owned duplicate diagnostics, lookup, and live iteration within one nonempty table generation; draining the table detaches existing iterators from later insertions, and `insert()` returns an idempotent exact-entry undo.
-- `AnonymousEntries<V>` Insertion-ordered anonymous storage whose unique internal keys keep equal values as independent registrations; it uses the same drained-generation iterator boundary, and `append()` returns an idempotent exact-entry undo.
+## Table of Contents
 
-The optional `@deepseek-ai/dsh-scope/invariant` companion owns that runtime assertion. It uses the generated `scoped-events.generated.ts` resolver map to require a carrier for every declared scoped event and, when the payload exposes its routing subject, require identity with the carrier key. The Program-backed generator derives the map from event declarations and real `scopeTarget(base, key)` calls.

-## Design contract
+-----
 
-The registration context determines both visibility and ownership, preventing a registration from being visible in one scope but disposed with another. Scopes route trusted same-process plugins; they are not sandboxes or authority boundaries. See the [agent-scope Agent Note](../../../.agents/notes/implemented/architecture/2026-07-08-agent-scope-contexts.md#security-and-authority-are-non-goals) for rationale and security non-goals.
+<a id="use-this-package"></a>
+## Use this package
 
-Scope-aware services define a concrete `ScopeLayer` that aggregates their heterogeneous tables and domain helpers. `ScopedLayers.effect()` accepts one synchronous action returning one synchronous undo, installs that undo before optional notification, and reclaims an exact-scope layer only when the complete aggregate is empty. `notify` defaults to `true`; the supplied callback owns whether observer failures throw or are contained. `EntryValues` remains internal, the storage classes are imported from the package root rather than a `/store` subpath, and the shared storage does not define registry-specific filtering or iteration policy. See the [shared scoped-layer storage Agent Note](../../../.agents/notes/implemented/architecture/2026-07-12-scoped-layers-store.md).
+Plugin authors use `dsh-scope` to give one agent (or one group) its own registration world. The registries in the core group build on it — a tool registered through `agent.ctx` is visible only to that agent — and the same primitive serves any custom registry or scope-filtered event.
 
-Handing out a scoped context hands out the minting plugin's service-resolution API (resolution walks the minting fiber's dependency chain, not the holder's) — mint it from the plugin whose dependencies the scoped registrations need to resolve.
+### Mint a scope
+
+`createScope(ctx, key)` creates a scope under `ctx`'s fiber: its `ctx` carries the scope tag, and everything registered through it is both scope-visible and scope-lifetime. `dispose()` unwinds every registration through the scope; `rawDispose` is the exact Cordis disposer for nesting the teardown in an ordered composite effect.
+
+```text
+const scope = createScope(ctx, agent)
+scope.ctx.on('agent/status', ({ agent, status }) => track(agent, status))
+// later:
+await scope.dispose()   // unwinds every registration made through scope.ctx
+```
+
+### Route scoped events
+
+`scopeTarget(base, key)` builds the opaque carrier a scope-filtered event dispatches with. Untagged listeners stay global; a listener tagged with `key` receives events for that key and its descendants. The carrier carries routing state only — the real subject travels in the event arguments.
+
+### Build a scoped registry layer
+
+Registry authors use `ScopedLayers`, `NamedEntries`, and `AnonymousEntries` to hold one eager global layer plus lazily created exact-scope layers: reads never create layers, `merge()` materializes insertion-ordered named shadows along the scope chain, and `effect()` derives visibility and ownership from the same context. A scoped layer is reclaimed only when its whole aggregate is empty.

+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the package realizes the behavior above; the observable contract is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The registration context determines both visibility and ownership: a registration made through a scoped context is visible in that scope and disposed with it, preventing a contribution from being visible in one scope but torn down with another. The primitive routes trusted same-process plugins; it is not a sandbox or an authority boundary. Handing out a scoped context also hands out the minting plugin's service-resolution API (resolution walks the minting fiber's dependency chain), so a scope is minted from the plugin whose dependencies the scoped registrations need.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | `createScope`, `scopeOf`, `scopeTarget`, `bindScopeParent`/`scopeParentOf`/`scopeChainOf`, carrier marks |
+| [`src/store.ts`](src/store.ts) | `ScopedLayers`, `NamedEntries`, `AnonymousEntries`, `ScopeLayer` |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion over the generated scoped-event map |
+| [`src/scoped-events.generated.ts`](src/scoped-events.generated.ts) | Generated resolver map of declared scoped events |
+
+### The parent chain
+
+One relation powers both directions: registration views inherit DOWN the chain (a child scope sees its ancestors' layers), while event admission extends UP it (a listener tagged with an ancestor receives events dispatched to a descendant key). Binding is once — a key that already has a parent throws, and only the returned binding may re-link it — and every link rejects a cycle. `scopeChainOf` returns `[key, parent, …]` nearest-first.
+
+### Event filtering
+
+`scopeTarget` composes the base's existing `Context.filter` with the scope predicate: an untagged listener is admitted; a tagged listener is admitted iff its tag is the dispatch key or an ancestor of it; `key === undefined` admits untagged listeners only. `{ global: true }` listeners bypass filtering. The `Scoped<T>` brand demands the carrier as the `this` type of a scope-filtered event, so dispatching with a bare subject is a compile error.

 ## Known Limitations and Deferred Work
 
+<a id="known-limitations-and-deferred-work"></a>
+
+These limits define when the primitive needs special care. They are current package constraints, not a task backlog.
+
 - **Only scope-aware APIs isolate state** — registries must file by `scopeOf()` and events must dispatch through `scopeTarget()`; an arbitrary Cordis service remains context-global merely because it is called through a scoped context.
-- **A context carries one nearest scope key** — the hierarchy lives in the key-level parent relation, not in context tags; nested scope CONTEXTS still shadow to a single tag, and multi-membership policy sets remain unsupported.
+- **A context carries one nearest scope key** — the hierarchy lives in the key-level parent relation, not in context tags; nested scope contexts still shadow to a single tag, and multi-membership policy sets remain unsupported.
 - **Service reachability comes from the scope minter** — handing out `Scope.ctx` also hands out the minting plugin's injected services, so a broader minter cannot later be narrowed by the holder.

-带作用域的注册原语。`createScope(ctx, key)` 创建一个带标签的 Cordis 上下文，其底层 fiber 拥有通过该上下文进行的每项注册。`scopeOf(ctx)` 读取标签；`scopeTarget(base, key)` 将带作用域的事件路由到键相同的监听器，同时让无作用域监听器保持全局可见。键可以构成可选的父链（`bindScopeParent`）：注册视图沿链**向下**继承——子作用域看得见祖先各层，近者遮蔽远者——事件放行沿链**向上**扩展——标签为祖先的监听器能收到子孙键的事件，反向永不成立。agent loop（智能体循环）为每个存活的 agent 创建一个作用域，agent preset 的常驻挂载则是其 agent 们的父作用域，但该机制与键的具体含义无关，底层包无需依赖两者即可使用。
+## 概述
 
-## 公开 API
+零依赖的 `dsh-scope` 库让注册拥有按 agent 归属的家。用 `createScope(ctx, key)` 创建带标签的上下文，通过它进行的每项注册只在一个作用域内可见，并随该作用域 dispose（资源释放）而撤销；用 `scopeOf(ctx)` 读取上下文的作用域标签；用 `scopeTarget(base, key)` 把带作用域的事件路由到键相同的监听器，同时让无标签监听器保持全局可见。键可以构成父链：子作用域看得见祖先的各层（近者遮蔽远者），标签为祖先的监听器能收到子孙键的事件——反向永不成立。该机制与键的具体含义无关：agent loop（智能体循环）为每个存活的 agent 创建一个作用域，agent preset 的常驻挂载则是其 agent 们的父作用域，但底层包无需依赖两者即可使用。构建必须按 agent 或按分组隔离贡献的注册表或事件表面时，请选择本包。
 
-- `createScope(ctx: Context, key: ScopeKey, options?): Scope`：在 `ctx` 的 fiber 下创建作用域。可以同步使用（effect 收集受 uid 门禁约束；服务解析会沿创建该作用域的插件依赖范围继续查找）。同进程、带类型的键受信任；处于非活动状态的创建上下文仍会通过 Cordis 失败（`INACTIVE_EFFECT`）。`options.parent` 在作用域可用之前经 `bindScopeParent` 绑定其外围作用域；绑定句柄不外泄。
-- `bindScopeParent(key, parent): ScopeParentBinding` / `scopeParentOf(key)` / `scopeChainOf(key)`：支撑两条链方向的父关系。绑定仅此一次：已有父级的键直接抛错，只有返回的绑定句柄的 `rebind(parent)` 才能重新绑定父级——即空白会话 recompose 的操作，仅当旧父之下产出的东西一概不被保留时才合法（这是持有方的约定——该关系看不见会话记录了什么）。绑定与每次 rebind 都拒绝会闭环的链接。`scopeChainOf` 返回 `[key, parent, …]`，最近者在前。
-- `Scope.ctx`：带标签的上下文。通过它进行的注册既具备作用域可见性，也服从作用域生命周期。派生上下文（一次 `extend`、挂载于其下的 fiber）继承标签；嵌套作用域会遮蔽外层标签（最近的标签生效）。
-- `Scope.rawDispose`：底层 fiber 的确切 Cordis disposer。组合式（generator）effect 会 yield 此函数，从而把作用域 teardown 嵌套在该 yield 位置（Cordis 按函数标识去重嵌套 effect；yield 一个包装函数会使作用域 teardown 成为并行的同级操作）。
-- `Scope.dispose(): Promise<void>`：通过作用域进行的每项注册所共用的幂等完全停稳边界。竞态调用或重复调用会等待同一次 teardown；即使 `rawDispose` 先调用了底层单次 Cordis disposer 也是如此。
-- `scopeOf(ctx: Context): ScopeKey | undefined`：上下文或其任意派生上下文携带的标签；`undefined` 表示上下文全局。
-- `scopeTarget(base: T, key: ScopeKey | undefined): Scoped<T>`：为按作用域筛选的事件构造不透明分发 `thisArg`。它把 `base` 现有的 `Context.filter` 与作用域谓词组合起来（无标签监听器 ⇒ 放行；有标签监听器 ⇒ 仅当标签 === key，或标签为 key 的祖先时放行；`key === undefined` ⇒ 仅放行无标签监听器）。载体只包含路由状态；真实主体由事件参数携带。带 `{ global: true }` 的监听器绕过筛选（Cordis 语义）。
-- `Scoped<T>`：编译期不透明载体 brand。按作用域筛选的事件要求它作为 `this` 类型，因此使用裸主体分发会产生编译错误。类型参数记录主体类型，但不公开其属性。
-- `isScopeCarrier(value)`/`carrierKeyOf(value)`：运行时载体标记，开发不变式使用它们断言每次按作用域筛选的分发都携带载体，而且载体键与参数所指名的主体一致。
-- `ScopeLayer`：一个注册表的完整全局贡献或精确作用域贡献的聚合约定；`isEmpty()` 控制带作用域层的回收。
-- `ScopedLayers<L>`：持有一个立即构造的全局层与惰性的精确作用域层。`peek()` 从不创建且刻意不看链（某作用域**自己**的贡献——限制、守卫——不得悄悄继承祖先的），`chainLayers()` 按最远祖先在前返回已存在的各层，`merge()` 沿链物化按插入序的具名遮蔽，`effect()` 从同一上下文推导可见性与所有权，并返回精确的 Cordis disposer。
-- `NamedEntries<V>`：按插入顺序排列的具名存储，调用方拥有重复项诊断、查找，以及一个非空表世代内的实时迭代。表清空后，现有迭代器与后续插入项脱离；`insert()` 返回幂等的精确条目撤销函数。
-- `AnonymousEntries<V>`：按插入顺序排列的匿名存储；唯一内部键使相同值仍作为独立注册存在。它使用相同的清空世代迭代器边界；`append()` 返回幂等的精确条目撤销函数。
+## 目录
 
-可选配套包 `@deepseek-ai/dsh-scope/invariant` 拥有该运行时断言。它使用生成的 `scoped-events.generated.ts` 解析器映射，要求每个已声明的带作用域事件都携带载体；当 payload 公开路由主体时，还要求路由主体与载体键严格相等。基于 Program 的生成器根据事件声明和真实的 `scopeTarget(base, key)` 调用生成该映射。

-## 设计约定
+-----
 
-注册上下文同时决定可见性和所有权，防止注册在一个作用域中可见、却随另一个作用域 dispose（资源释放）。作用域用于路由受信任的同进程插件；它们不是沙箱或权限边界。原理与明确排除的安全目标见 [agent 作用域 Agent Note](../../../.agents/notes/implemented/architecture/2026-07-08-agent-scope-contexts.zh.md#security-and-authority-are-non-goals)。
+<a id="use-this-package"></a>
+## 使用本包
 
-感知作用域的服务会定义具体 `ScopeLayer`，聚合各自不同的表与领域辅助函数。`ScopedLayers.effect()` 接受一个返回同步撤销函数的同步动作，在可选通知前安装该撤销函数，并且只有在完整聚合为空时才回收精确作用域层。`notify` 默认为 `true`；由所提供的回调决定观测方失败是向外抛出还是在内部处理。`EntryValues` 保持内部可见；存储类从包根而非 `/store` 子路径导入；共享存储不定义注册表专属的筛选或迭代策略。详见[共享作用域层存储 Agent Note](../../../.agents/notes/implemented/architecture/2026-07-12-scoped-layers-store.zh.md)。
+插件作者使用 `dsh-scope` 为单个 agent（或单个分组）提供独立的注册世界。core 分组中的注册表都构建在它之上——通过 `agent.ctx` 注册的工具只对该 agent 可见——同样的原语也服务于任何自定义注册表或带作用域的事件。
 
-交出带作用域的上下文，也会交出创建该上下文的插件的服务解析范围（解析会沿创建者 fiber 的依赖链，而非持有者的依赖链行进），因此应由具备这些带作用域注册所需依赖的插件来创建它。
+### 创建作用域
 
-## 已知限制与暂缓事项
+`createScope(ctx, key)` 在 `ctx` 的 fiber 下创建作用域：其 `ctx` 携带作用域标签，通过它进行的每项注册既具备作用域可见性，也服从作用域生命周期。`dispose()` 撤销通过该作用域进行的每项注册；`rawDispose` 是确切 Cordis disposer，用于把 teardown 嵌套进有序组合 effect。
+
+```text
+const scope = createScope(ctx, agent)
+scope.ctx.on('agent/status', ({ agent, status }) => track(agent, status))
+// later:
+await scope.dispose()   // unwinds every registration made through scope.ctx
+```
+
+### 路由带作用域的事件
+
+`scopeTarget(base, key)` 构造带作用域事件分发所用的不透明载体。无标签监听器保持全局；标签为 `key` 的监听器接收该键及其后代的事件。载体只携带路由状态——真实主体由事件参数携带。
+
+### 构建带作用域的注册表层
+
+注册表作者使用 `ScopedLayers`、`NamedEntries` 与 `AnonymousEntries` 持有一个立即构造的全局层加惰性创建的精确作用域层：读取从不创建层，`merge()` 沿作用域链物化按插入序的具名遮蔽，`effect()` 从同一上下文推导可见性与所有权。只有当整个聚合为空时才回收作用域层。

+### 设计理念
+
+注册上下文同时决定可见性与所有权：通过带作用域上下文进行的注册在该作用域内可见、并随其 dispose，从而防止贡献在一个作用域中可见、却随另一个作用域拆除。该原语用于路由受信任的同进程插件；它不是沙箱或权限边界。交出带作用域的上下文，也会交出创建该上下文的插件的服务解析范围（解析沿创建者 fiber 的依赖链行进），因此作用域应由具备这些带作用域注册所需依赖的插件来创建。

+
+### 事件筛选
+
+`scopeTarget` 把基对象的现有 `Context.filter` 与作用域谓词组合起来：无标签监听器放行；有标签监听器仅当标签为分发键或其祖先时放行；`key === undefined` 只放行无标签监听器。带 `{ global: true }` 的监听器绕过筛选。`Scoped<T>` brand 要求带作用域事件以载体作为 `this` 类型，因此用裸主体分发会产生编译错误。

 - **只有感知作用域的表层才会隔离状态**：注册表必须按 `scopeOf()` 归档，事件必须通过 `scopeTarget()` 分发；仅仅通过带作用域的上下文调用任意 Cordis 服务，并不会改变该服务仍为上下文全局这一事实。
-- **一个上下文只携带一个最近的作用域键**：层级关系存在于键级父关系中而非上下文标签里；嵌套作用域**上下文**仍遮蔽为单一标签，多成员策略集仍不受支持。

-Event-sourced session log and in-memory store. A `Session` is the append-only source of truth for an agent's whole interaction history — the LLM message history is *derived* from it. A **surface** layer (an ordered projection of message-producing events) is maintained on top of the raw log for efficient derivation and compaction.
+## Summary
 
-The optional `@deepseek-ai/dsh-session/invariant` companion registers this package's relational trace checks with `ctx.invariants`: monotonic sequence numbers, turn/step enclosure, and same-step tool call/result pairing. It replays existing sessions when loaded or reloaded; storage validation, snapshotting, freezing, cited source-event validation, and surface acceptance remain always-on responsibilities of the root session package.
+`dsh-session` provides the append-only session log that records an agent's whole interaction history — the single source of truth every model-visible fact flows through. The LLM message history is *derived* from the log (`deriveMessages()`), never stored separately, so replay is re-derivation from the same events and compaction can shadow older surface entries without deleting history. The package also provides the in-memory store (`ctx.sessions`), the typed `SessionEvent` vocabulary that plugins extend by declaration merging, and the surface layer that orders message-producing events. Persistence is deliberately a separate concern: backends subscribe to `session/event` and flush on `session/flush`. Choose it as the foundation of any agent session; it runs no model calls itself.
 
-## Service: `SessionStore` (ctx key: `sessions`)
+## Table of Contents
 
-Creates and holds event-sourced `Session` instances. Persistence is intentionally not implemented here — plugins subscribe to `session/event`, flush on `session/flush`, and may mirror the paired `session/created`/`session/disposed` lifecycle.

-### Public API
+-----
 
-- `ctx.sessions.create(id?, { seed?, meta? }?)` validates and detaches durable seed/header data, fills the version and id, defaults `createdAt` to now, publishes the session, and binds it to the calling fiber. Persisted reconstruction supplies its original `createdAt`, `seedLength`, and `delegationDepth`.
-- `ctx.sessions.flush(session)` dispatches the awaited parallel durability checkpoint through the session's captured scope. Every listener starts and the call waits for all to settle before reporting failure; unpublished, detached, and stale objects reject.
-- `ctx.sessions.fork(source, boundary?, childSessionId?): Session` — Resolve a live session object or id, select a seed through the inclusive `boundary` event seq (default: current last event), require that prefix to end outside an open turn, and create a live child session with lineage metadata.
-- `ctx.sessions.get(id: SessionId): Session | undefined`
-- `ctx.sessions.list(): Session[]`
+<a id="use-this-package"></a>
+## Use this package
 
-#### Advanced: ordered-teardown lifecycle primitives
+Mount `dsh-session` wherever a session must exist. It creates and holds event-sourced `Session` instances in memory; durable storage is layered on by a persistence plugin that subscribes to the `session/event` feed.
 
-Use the split lifecycle only when teardown must be ordered with another resource:
+### Create and inspect sessions
 
-- `prepare(id?, options?)` validates and constructs without publication.
-- `enter(session)` performs the collision check, publishes without announcing, and returns an entry-bound idempotent detach. Concurrent same-id preparations are allowed, but only one entry succeeds; a stale detach cannot remove its replacement.
-- `announce(session)` emits the single creation edge and rejects repeat or reentrant announcements. Detach during that dispatch is deferred and later emits the paired disposal edge; an unannounced entry emits neither lifecycle edge.
+`ctx.sessions.create()` builds a live session bound to the calling fiber; `get(id)` and `list()` find sessions, and `fork()` creates a child session from a stable prefix of a live one.
 
-`dsh-agent-loop` uses this split so final loop flush precedes session detach; see the [ownership Agent Note](../../../.agents/notes/implemented/architecture/2026-06-18-agent-lifecycle-and-ownership-contracts.md).
+```text
+const session = ctx.sessions.create(sessionId, { meta: { cwd: '/workspace' } })
+ctx.sessions.get(sessionId)      // the live session
+ctx.sessions.list()              // every live session, in creation order
+```
 
-### Live service events
+### Append and derive
 
-The store pairs announced creation with disposal, publishes post-commit append notifications with per-listener containment, and provides an awaited durability checkpoint. Exact signatures and scope behavior live in the generated region of [session.md](../../../docs/subsystems/session.md#cordis-surface); payloads live in the [persistence catalog](../../../docs/persistence-catalog.md).
+`session.append(type, data, opts?)` commits one typed event — it snapshots and freezes the payload, validates it as lossless JSON, and notifies observers. `session.deriveMessages()` projects the log into the `Message[]` the model sees, incrementally and cached:
 
-### Class: `Session`
+```text
+session.append('user/message', { role: 'user', content: [{ type: 'text', text: 'hello' }], source: { kind: 'user' } },
+  { surfaceOp: 'append' })
+session.deriveMessages()         // the derived model history
+```
 
-Plain class (not a Cordis Service). Create live sessions through `ctx.sessions.create()` and detached replay or inspection sessions through `Session.create()`; the detached factory does not publish lifecycle events or bind the session to a fiber.
+Surface events (`user/message`, `assistant/message`, `tool/result`) must declare how they join the ordered surface; raw chunks, boundaries, and other log-only events never produce a message.
 
-- `session.append(type, data, opts?)` snapshots and freezes durable data and surface metadata, validates marker shape, cited source-event seqs, complete replacement coverage, and content-only single-result `tool/result` rewrites, commits synchronously, then notifies observers with independent failure containment. Reentrant attached-session appends reject, and runtime checks cover widened unions and loaded logs.
-- `session.deriveMessages()` incrementally projects each new surface entry once and returns a fresh array over the complete identified, frozen messages stored by those entries. Assistant messages preserve the provider and model that produced them plus adapter-private replay state in their model source. A surface rewrite rebuilds the projection; there is no raw-log fallback.
-- `session.deriveEventMessage(event)` is the canonical per-event projection used by reconstruction and request checks.
-- `session.surface` exposes the readonly `SessionSurface` view owned by the session's single incremental surface manager; `replaceGeneration` changes on every committed rewrite.
-- `session.events` is a cached frozen snapshot invalidated by append; accepted events remain deeply frozen.
-- `session.seq`, `session.id` — current sequence and readonly typed identity.
-- `session.header: SessionHeader` — detached, deep-frozen creation metadata (`version`, `id`, `createdAt`, optional `cwd`/`parentSession`/`seedLength`/`delegationDepth`). Construction validates the durable record and requires its id to match `session.id`.
+### Fork a session
 
-### Lossless JSON utilities
+`ctx.sessions.fork(source, boundary?, childSessionId?)` selects source events through an inclusive `boundary` seq (default: the current last event), requires the prefix to end outside an open turn, and creates a live child session with lineage metadata. A tool-time delegation that must branch mid-turn clips to a completed prefix instead.
 
-Durable values use one lossless-JSON representation. `isJsonValue(value)` checks that representation; `snapshotJsonValue(value)` validates and detaches it in one pass and returns `undefined` for invalid input. The source JSDoc owns the exact accepted value set.
+### Flush durable state
 
-Session-event import separates ownership from message validation. `snapshotSessionEvent(event)` clones a borrowed event before validating and freezing its identified message. `adoptSessionEvent(event)` performs the same message work in place and returns the original event; callers may use it only when they transfer an exclusively owned object graph with no mutable child shared with another event.
+`ctx.sessions.flush(session)` dispatches the awaited durability checkpoint: every persistence listener flushes and the call settles after all of them. A producer that needs an immediate durability barrier awaits it instead of assuming the write-behind drained.
 
-### Chunk-row storage codec (`chunk-rows.ts`)
+-----
 
-The shared [row codec](src/chunk-rows.ts) losslessly converts event sequences to compact rows and back. It preserves unrecognized events verbatim and rejects malformed encoded rows. Persistence backends decide whether to enable packed writes; bounded history transports may use the same rows while retaining the complete logical event interval and exposing exact decoding to consumers that need token boundaries.
+<a id="understand-the-implementation"></a>
+## Understand the implementation
 
-### Surface types
+<details>
+<summary>Implementation internals — click to expand</summary>
 
-This package owns ordered surface projection, replacement validation, replay, and the type guards that distinguish append-origin from replacement events. The [surface type catalog](../../../docs/subsystems/session.md#surface-types) owns the exact shapes and field semantics. A human transcript must project append-origin events rather than `session.surface`, because landed replacements shadow history the reader already saw; model-facing consumers continue to read `session.surface`.
+This section explains how the package realizes the behavior above; the observable contract is covered in [Use this package](#use-this-package).
 
-### Request-header reconstruction (`request-header.ts`)
+### Design concept
 
-`request/header` records a full canonical snapshot of the non-history request envelope with reason `initial`, `resume`, `change`, or `series`. `series` repeats an unchanged envelope when `agent/pre-step` explicitly starts a distinct model-message series or a surface replacement changes the model's message list; when that boundary coincides with an envelope change, the `change` snapshot carries `startsSeries: true` so both facts survive. Ordinary append-only later turns remain in the current series. Same-series steps and retries with an unchanged envelope keep using the latest snapshot. Repeating the complete system prompt and tool catalog grows the log linearly with message series, but keeps every header self-contained for partial-window rendering and exact request reconstruction; a lightweight reference marker would require predecessor availability and a second replay representation. Its optional `adapterDefaults` map marks effective `reasoningEffort` or `maxTokens` values materialized by exact-model resolution, allowing the next request proposal to distinguish them from explicit conversation settings. `foldRequestHeader()` selects the latest snapshot; legacy delta events and the removed `fallback` reason are rejected. See the [reconstructable-requests Agent Note](../../../.agents/notes/implemented/architecture/2026-07-05-reconstructable-requests.md).
+The package is built on event sourcing: a `Session` is an append-only log of typed `SessionEvent`s, and everything else — model history, transcripts, telemetry, titles, persistence — derives from that stream. The surface is a derived projection: an incremental manager validates append candidates, advances the ordered view from committed events, and tracks a `replaceGeneration` that bumps on every committed rewrite. Model-visible means logged: anything that reaches a model request must be reconstructable from the log. The shared [row codec](src/chunk-rows.ts) losslessly converts event sequences to compact rows and back, preserves unrecognized events verbatim, and rejects malformed rows. Persistence backends decide whether to pack writes; bounded history transports can use the same rows while retaining the complete logical interval and exact decoding for consumers that need token boundaries.
 
-A `user/message` stores the complete `UserMessage` directly, including the identity created before inbox routing or step entry. It renders its `content` verbatim whether it is a direct human prompt, a synthetic injection, or an entered goal round; its typed `source` is the only channel that tells them apart and carries any domain-specific durable facts. `assistant/message` and `tool/result` likewise store complete message values. Turn execution remains enclosed by `turn/start` and `turn/end`; `agent.inject()` queues input until a later pre-step claims it and returns it in an enter decision.
+### Request headers
 
-`tool/result` persists one identified user-role tool-result message, optional internal failure identity, and optional presentation metadata. A tool's successful canonical `value` and human-readable canonical failure message remain execution-local; rendered error content is the replay-authoritative message.
+`request/header` stores a full canonical snapshot of the non-history request envelope with reason `initial`, `resume`, `change`, or `series`. An explicit message-series start or a surface replacement writes a `series` snapshot when the envelope is unchanged; a simultaneous change uses `startsSeries: true`. Same-series steps, retries, and ordinary later turns inherit the latest snapshot. `adapterDefaults` distinguishes values resolved by the adapter from explicit settings, and `foldRequestHeader()` selects the latest snapshot. This self-contained record supports partial-window rendering and exact reconstruction at the cost of growth per message series; the [reconstructable-requests Agent Note](../../../.agents/notes/implemented/architecture/2026-07-05-reconstructable-requests.md) owns the detail.
 
-### Session event vocabulary (`types.ts`)
+### Source map
 
-The generated [persistence log event catalog](../../../docs/persistence-catalog.md) enumerates each append-only event type with its payload, surface badge, and declaration site. Token accounting reads per-step `assistant/chunk { type: 'usage' }` records and treats `assistant/message.usage` as the committed-step fallback when no usage chunk exists; failed model-request attempts have no assistant message. Each `assistant/message` records the provider, model, and optional replay state.

-Merge-extensible via `SessionEventMap` — a plugin declaration-merges its own types (the compaction seam's `compaction/*`, bounded recovery's non-surface `llm/retry`, the hook bridges' `hook/*`); merged members appear in the same catalog. A plugin owns the relational invariant for its merged events, including whether a log-only event may appear between turns. A producer that requires durability appends through `Session` and then awaits `ctx.sessions.flush(session)` without fabricating an execution turn.
+### Append validation
 
-Also defines `TurnEndReasonMap`, the merge-extensible `kind`-tagged sum type for turn endings. `turn/start` carries only the turn number; the following entered `user/message` batch records its input, while `llm/retry` records request recovery.
+Every append runs one recursive pass that reads, validates, and copies each nested value once, so a stateful getter cannot supply one value to validation and another to storage. Non-lossless-JSON payloads (BigInt, cycles, sparse arrays, `-0`, exotic prototypes) are rejected at the append site, before any backend flush. Surface events additionally validate marker shape, cited source-event seqs, and complete shadowed-node coverage for replacements.
 
-An interrupted live turn ends with `{ kind: 'aborted', reason: AgentCancelCause }`, preserving the typed cancellation cause in the durable transcript. Persistence imports the coarse aborted outcome from the supported older format as `{ kind: 'aborted', reason: { kind: 'legacy' } }`, because that record did not retain its caller. A turn failure carries `{ kind: 'error', error }`; crash recovery alone synthesizes `{ kind: 'interrupted' }`.
+### Derived history
 
-Every `SessionEvent` carries three optional top-level fields (structural metadata):
+`deriveMessages()` caches each surface node's projection once and returns a fresh array per call over shared, deep-frozen messages; each of the three surface event types (`user/message`, `assistant/message`, `tool/result`) projects its own message kind — user content verbatim, the assembled assistant message with its provider and model, or a user-role tool result. A surface rewrite rebuilds the projection — there is no raw-log fallback, so the surface is the single source of derived history.
 
-- `sourceEventSeqs?: number[]` — seq numbers of earlier events cited as sources (e.g., the `assistant/chunk` seqs behind an `assistant/message`, or the shadowed entries behind a compaction replacement entry). On `assistant/message`, a present `[]` records a known empty provider stream, while omission means a legacy or foreign event did not record the source stream; other surface events require a non-empty list when this field is present.
-- `surfaceOp?: SurfaceOp` — how this event entered the surface. Absent for non-surface events (boundaries, chunks, usage, errors).
-- `ignorable?: true` — marks an event a reader may safely skip when it does not recognize the type; absent means required, so an unknown-type event refuses session reconstruction ([mechanism](../../../.agents/notes/implemented/architecture/2026-08-10-session-log-version-mechanism.md)).
+### The request header
 
-### Metadata types (`types.ts`)
+The loop logs a full canonical `request/header` snapshot (call config, adapter defaults, rendered system prompt, assembled tool schemas) at each loop-instance boundary and on change; `foldRequestHeader(events)` reconstructs it by selecting the latest snapshot, making every conversation request a pure function of the log. Route metadata (`request/context`) is separate logged state appended only when the provider, model, or capacity differs.
 
-- `SessionHeader` — session metadata written once when published as `Session.header`, where detachment and deep-freezing enforce immutability at runtime: `{ version, id, createdAt, cwd?, parentSession?, seedLength?, delegationDepth? }`. Persistence loaders may return mutable detached copies of the same data type. Owned here (beside `SessionId`) because `Session.header` is typed by it; persistence backends re-export it rather than own it (which would force a package cycle).
+</details>
 
-### Extension points
+-----
 
-- Persistence plugins: subscribe to `session/event` (write-behind) and drain on `session/flush` (awaited) and fiber dispose. A durable backend reads the log and reloads it into a live session; the metadata contract (`SessionHeader`, `session.header`) is what such a backend stores beside the log.
-- Replay/fork: `create(id, { seed })` validates and freezes a contiguous current-format log and rebuilds its surface; request headers require provider/model, and assistant messages require provider/model provenance. Persistence owns read compatibility before constructing this current-format seed. `fork(source, boundary?, childSessionId?)` selects a completed-turn prefix and records lineage.
-- Compaction: `dsh-compaction-basic` appends a `user/message` replacement for summary checkpoints, while `dsh-compaction-tool-result-pruner` appends a content-only `tool/result` replacement. Tool-pairing boundary policy and its cache belong to the [`dsh-compaction` seam](../../compaction/compaction/README.md), while this package owns ordered surface membership, replacement validation, and `replaceGeneration`.

 ## Model Experience
 
 ### Derived message history
 
 #### What the model sees
 
-The model receives the complete messages from `user/message`, `assistant/message`, and `tool/result` surface entries verbatim. Their identities, roles, sources, and content blocks are the same values established at creation; projections do not mint identities. Direct prompts and injected context remain separate `user/message` events whose sources preserve their provenance. A prompt envelope changes only human presentation; its prefix context and request delimiter are already present in the event content. Tool calls live inside assistant messages. Chunks, boundaries, usage, hook records, todo records, and other log-only events add no message.

 ## Known Limitations and Deferred Work
 
-- **Session branching/tree** (pi-style entry tree) — deferred unless needed beyond boundary-based `fork()`.
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define when the session store needs special care. They are current package constraints, not a task backlog.
+
 - **`fork()` cuts only at stable boundaries of live sessions** — the selected prefix must end outside an open turn and the source must be in the store; forking a persisted-but-unloaded session is excluded from the [fork API](../../../.agents/notes/implemented/feature/2026-06-30-session-store-fork-api.md).
-- **`SESSION_FORMAT_VERSION` stays pinned at `0`** — pre-release, no broad compatibility implied: `Session` accepts only current seed shapes, and a backend refuses any other version naming the direction (newer: "written by a newer harness — upgrade"; older: no upgrade path ships yet). Unknown event types refuse the same way unless marked `ignorable` in the envelope; the versioning mechanism is the [session-log-version-mechanism note](../../../.agents/notes/implemented/architecture/2026-08-10-session-log-version-mechanism.md). Narrow storage import upgrades belong to the persistence boundary ([policy](../../../AGENTS.md), [pre-identity message recovery](../../../.agents/notes/implemented/bug-fix/2026-07-28-load-pre-identity-session-messages.md)).
+- **`SESSION_FORMAT_VERSION` stays pinned at `0`** — pre-release, no broad compatibility implied: `Session` accepts only current seed shapes, a backend refuses any other version, and unknown event types refuse reconstruction unless marked `ignorable` in the envelope ([mechanism](../../../.agents/notes/implemented/architecture/2026-08-10-session-log-version-mechanism.md)).
 - **`TurnEndReasonMap` omits the ACP-named `refusal` / `max_turn_requests` variants** — producer-gated: they land when an adapter or the loop first emits them.
+- **No session tree beyond fork** — a pi-style entry tree over branched sessions is deferred unless a consumer needs more than boundary-based forking.

-事件溯源的会话日志和内存存储。`Session` 是 agent（智能体）全部交互历史的仅追加真源，LLM（大语言模型）消息历史由它*派生*。原始日志之上维护一个 **surface** 层（产生消息事件的有序投影），以便高效派生和压缩（compaction）。
+## 概述
 
-可选配套入口 `@deepseek-ai/dsh-session/invariant` 将此包的关系轨迹检查注册到 `ctx.invariants`：序号单调递增、轮次／步骤闭合，以及同一步骤内的工具调用／结果配对。加载或重新加载时，它会回放现有会话；存储校验、快照、冻结、被引用的源事件校验和 surface 准入仍始终由根会话包负责。
+`dsh-session` 提供仅追加的会话日志，记录 agent（智能体）的完整交互历史——每个模型可见事实都流经的单一真源。LLM（大语言模型）消息历史由日志*派生*（`deriveMessages()`），从不另行存储，因此回放就是对同一批事件重新派生，压缩（compaction）也可以遮蔽较旧的表层条目而不删除历史。该包还提供内存存储（`ctx.sessions`）、插件通过声明合并扩展的类型化 `SessionEvent` 词汇，以及为产生消息的事件排序的 surface 层。持久化刻意是独立关注点：后端订阅 `session/event` 并在 `session/flush` 时刷新。作为任何 agent 会话的基础时请选择本包；它本身不运行模型调用。
 
-## 服务：`SessionStore`（ctx 键：`sessions`）
+## 目录
 
-创建并持有事件溯源的 `Session` 实例。这里有意不实现持久化：插件订阅 `session/event`，在 `session/flush` 时刷新，并可镜像成对的 `session/created`／`session/disposed` 生命周期。

-- `ctx.sessions.create(id?, { seed?, meta? }?)` 校验持久种子／头部数据并生成脱离副本，补齐版本和 id，在未提供 `createdAt` 时使用当前时间，发布会话并将其绑定到调用方 fiber。持久化重建会提供原始的 `createdAt`、`seedLength` 和 `delegationDepth`。
-- `ctx.sessions.flush(session)` 通过会话捕获的作用域分发一个需等待完成的并行持久性检查点。每个监听器都会启动；调用会等待全部结算后才报告失败。未发布、已脱离和陈旧的对象会被拒绝。
-- `ctx.sessions.fork(source, boundary?, childSessionId?): Session`：解析实时会话对象或 id，选取截至 `boundary` 事件序号（含该事件）的种子（默认为当前最后一个事件），要求所选前缀结束时没有开放轮次，再创建带谱系元数据的实时子会话。
-- `ctx.sessions.get(id: SessionId): Session | undefined`
-- `ctx.sessions.list(): Session[]`
+<a id="use-this-package"></a>
+## 使用本包
 
-#### 高级：有序清理生命周期原语
+在必须存在会话的任何地方挂载 `dsh-session`。它在内存中创建并持有事件溯源的 `Session` 实例；持久存储由订阅 `session/event` 流的持久化插件叠加。
 
-仅在清理必须与另一项资源排序时使用拆分生命周期：
+### 创建与检查会话
 
-- `prepare(id?, options?)` 校验并构造，但不发布。
-- `enter(session)` 执行冲突检查，在不通知的情况下发布，并返回一个绑定到该条目的幂等脱离函数。允许并发准备相同 id，但只有一个条目能够成功进入；陈旧的脱离函数无法移除其替代项。
-- `announce(session)` 发出唯一一次创建边，并拒绝重复或重入通知。该次分发期间请求的脱离操作会延后，之后再发出成对的释放边；未通知的条目不会发出任何生命周期边。
+`ctx.sessions.create()` 构建绑定到调用方 fiber 的实时会话；`get(id)` 与 `list()` 查找会话，`fork()` 从实时会话的稳定前缀创建子会话。
 
-`dsh-agent-loop` 使用这一拆分，以保证循环的最终刷新先于会话脱离；详见[所有权 Agent Note](../../../.agents/notes/implemented/architecture/2026-06-18-agent-lifecycle-and-ownership-contracts.zh.md)。
+```text
+const session = ctx.sessions.create(sessionId, { meta: { cwd: '/workspace' } })
+ctx.sessions.get(sessionId)      // the live session
+ctx.sessions.list()              // every live session, in creation order
+```
 
-### 实时服务事件
+### 追加与派生
 
-会话存储会将已通知的创建与释放配对，在提交后发布追加通知并逐个监听器收容失败，同时提供受等待的持久性检查点。确切签名和作用域行为见 [session.md](../../../docs/subsystems/session.zh.md#cordis-surface) 的生成区块；载荷见[持久化目录](../../../docs/persistence-catalog.zh.md)。
+`session.append(type, data, opts?)` 提交一个类型化事件——它先快照并冻结载荷、校验其为无损 JSON，再通知观察者。`session.deriveMessages()` 把日志投影为模型看到的 `Message[]`，采用增量且有缓存的方式：
 
-### 类：`Session`
+```text
+session.append('user/message', { role: 'user', content: [{ type: 'text', text: 'hello' }], source: { kind: 'user' } },
+  { surfaceOp: 'append' })
+session.deriveMessages()         // the derived model history
+```
 
-普通类（不是 Cordis 服务）。活跃会话通过 `ctx.sessions.create()` 创建，脱离态的回放或检查会话通过 `Session.create()` 创建；脱离态工厂不会发布生命周期事件，也不会将会话绑定到 fiber。
+表层事件（`user/message`、`assistant/message`、`tool/result`）必须声明如何进入有序 surface；原始分片、边界与其他仅日志事件从不产生消息。
 
-- `session.append(type, data, opts?)` 会为持久数据和 surface 元数据制作快照并冻结它们，校验标记形态、被引用的源事件 seq、替换覆盖完整性，以及仅修改内容的单个 `tool/result` 重写，随后同步提交，再在彼此独立的失败收容下通知观察者。对已挂接会话的重入追加会被拒绝，运行时检查也覆盖扩宽后的联合类型和已加载日志。
-- `session.deriveMessages()` 对每个新的 surface 条目只做一次增量投影，并返回一个新数组，其中包含这些条目存储的完整、带标识且冻结的消息。assistant 消息的模型来源会保留生成该消息的提供方和模型，以及适配器私有回放状态。surface 重写会重建投影；不存在原始日志回退。
-- `session.deriveEventMessage(event)` 是重建和请求检查使用的规范逐事件投影。
-- `session.surface` 暴露只读 `SessionSurface` 视图，由会话唯一的增量 surface 管理器所有；每次提交重写，`replaceGeneration` 都会变化。
-- `session.events` 是按追加失效的缓存冻结快照；已接受事件保持深度冻结。
-- `session.seq`、`session.id`：当前序号和只读类型化身份。
-- `session.header: SessionHeader`：脱离、深冻结的创建元数据（`version`、`id`、`createdAt`，以及可选的 `cwd`／`parentSession`／`seedLength`／`delegationDepth`）。构造时会校验持久记录，并要求其中的 id 与 `session.id` 一致。
+### 派生会话的 fork
 
-### 无损 JSON 工具
+`ctx.sessions.fork(source, boundary?, childSessionId?)` 选取截至 `boundary` 事件序号（含该事件）的源事件（默认：当前最后一个事件），要求所选前缀结束时没有开放轮次，再创建带谱系元数据的实时子会话。必须在轮次中途分支的工具时委派会裁剪到已完成前缀。
 
-持久值使用一种无损 JSON 表示。`isJsonValue(value)` 检查该表示；`snapshotJsonValue(value)` 在一趟处理中校验并分离该表示，无效输入返回 `undefined`。源码 JSDoc 负责记录确切的可接受值集合。
+### 刷新持久状态
 
-会话事件导入将所有权与消息校验分开处理。`snapshotSessionEvent(event)` 会先克隆借用的事件，再校验并冻结其中带标识的消息。`adoptSessionEvent(event)` 原地执行相同的消息处理并返回原事件；调用方只有在移交独占的对象图，且该对象图没有与其他事件共享可变子对象时，才可以使用此函数。
+`ctx.sessions.flush(session)` 分发需等待完成的持久性检查点：每个持久化监听器都会刷新，调用在所有监听器结算后完成。需要立即持久性屏障的生产方应等待它，而不是假定写后刷新已完成。
 
-### 分片行存储编解码器（`chunk-rows.ts`）
+-----
 
-共享的[行编解码器](src/chunk-rows.ts)在事件序列与紧凑行之间无损转换。它会逐字保留无法识别的事件，并拒绝形态错误的编码行。持久化后端决定是否启用打包写入；有界历史传输也可以使用同一种行，同时保留完整的逻辑事件区间，并向需要 token 边界的消费方提供精确解码能力。
+<a id="understand-the-implementation"></a>
+## 理解实现
 
-### Surface 类型
+<details>
+<summary>实现细节——点击展开</summary>
 
-此包拥有有序 surface 投影、替换校验、回放，以及区分追加来源事件与替换事件的类型守卫。[surface 类型目录](../../../docs/subsystems/session.zh.md#surface-types)拥有精确形状与字段语义。面向人的 transcript（文本记录）必须投影追加来源事件，而不是 `session.surface`，因为已落地的替换会遮蔽读者已经看到的历史；面向模型的消费方继续读取 `session.surface`。
+本节解释该包如何实现上述行为；可观察约定已在[使用本包](#use-this-package)中完整说明。
 
-### 请求头重建（`request-header.ts`）
+### 设计理念
 
-`request/header` 记录非历史请求封装的完整规范快照，其原因为 `initial`、`resume`、`change` 或 `series`。当 `agent/pre-step` 显式开启独立的模型消息序列，或表层替换改变模型消息列表时，`series` 会重复记录内容未变的封装；如果该边界与封装变化同时发生，`change` 快照会携带 `startsSeries: true`，从而同时保留这两个事实。普通的仅追加后续 turn 仍属于当前序列。同一序列内封装未变的 step 和重试继续使用最新快照。重复完整系统提示词和工具目录会使日志随消息序列线性增长，但能让每个 header 自包含，以支持局部窗口渲染和精确请求重建；轻量引用标记则会要求前序始终可用，并引入第二种回放表示。其可选 `adapterDefaults` 映射会标记由精确模型解析填入的生效 `reasoningEffort` 或 `maxTokens` 值，使下一次请求提议能够将它们与显式对话设置区分开。`foldRequestHeader()` 选择最新快照；旧版增量事件和已移除的 `fallback` 原因会被拒绝。详见[可重建请求 Agent Note](../../../.agents/notes/implemented/architecture/2026-07-05-reconstructable-requests.zh.md)。
+该包建立在事件溯源之上：`Session` 是类型化 `SessionEvent` 的仅追加日志，其他一切——模型历史、transcript、遥测、标题、持久化——都从这条流派生。surface 是派生投影：一个增量管理器校验追加候选、根据已提交事件推进有序视图，并跟踪每次已提交重写都会递增的 `replaceGeneration`。模型可见即已记录：任何到达模型请求的内容都必须能从日志重建。共享的[行编解码器](src/chunk-rows.ts)在事件序列与紧凑行之间无损转换，逐字保留无法识别的事件，并拒绝形态错误的行。持久化后端决定是否打包写入；有界历史传输可以使用同一种行，同时保留完整逻辑区间，并为需要 token 边界的消费方提供精确解码。
 
-`user/message` 会直接存储完整的 `UserMessage`，其中包括收件箱路由或进入步骤前创建的标识。无论它是直接人类提示词、合成注入，还是已进入的 Goal Round，都会原样呈现其 `content`；带类型的 `source` 是区分三者的唯一通道，并携带各领域专有的持久事实。`assistant/message` 和 `tool/result` 也会存储完整的消息值。轮次执行仍由 `turn/start` 与 `turn/end` 包围；`agent.inject()` 会把输入排队，直到后续某次 pre-step 领取它，并在 enter 决策中返回它。
+### 请求 header
 
-`tool/result` 持久保存一条带标识、user-role 的工具结果消息，以及可选内部失败标识和可选呈现元数据。工具成功时的规范 `value` 和便于人类阅读的规范失败消息只存在于执行本地；渲染后的错误内容是回放权威消息。
+`request/header` 存储非历史请求 envelope 的完整规范快照，原因为 `initial`、`resume`、`change` 或 `series`。显式消息序列起点或表层替换会在 envelope 不变时写入 `series` 快照；同时发生变化时使用 `startsSeries: true`。同一序列内的步骤、重试与普通后续轮次继承最新快照。`adapterDefaults` 区分由适配器解析的值与显式设置，`foldRequestHeader()` 选择最新快照。这种自包含记录以每个消息序列增加存储为代价，支持局部窗口渲染与精确重建；细节由[可重建请求 Agent Note](../../../.agents/notes/implemented/architecture/2026-07-05-reconstructable-requests.zh.md)负责。
 
-### 会话事件词汇（`types.ts`）
+### 源码地图
 
-生成的[持久化日志事件目录](../../../docs/persistence-catalog.zh.md)逐成员列举仅追加日志的事件类型、载荷、surface 标记与声明位置。Token 记账读取每个步骤的 `assistant/chunk { type: 'usage' }` 记录；如果没有用量分片，则将 `assistant/message.usage` 作为已提交步骤的后备。失败的模型请求尝试没有 assistant 消息。每条 `assistant/message` 都会记录提供方、模型和可选回放状态。

-`SessionEventMap` 可通过合并扩展：插件使用声明合并添加自身类型（压缩 seam 的 `compaction/*`、有界恢复的非 surface `llm/retry`、钩子桥接层的 `hook/*`）；合并成员会出现在同一目录中。插件拥有其合并事件的关系不变量，包括是否允许纯日志事件出现在轮次之间。需要持久性的生产方通过 `Session` 追加，再等待 `ctx.sessions.flush(session)`，无需虚构一个执行轮次。
+### 追加校验
 
-此包还定义 `TurnEndReasonMap`，即用于轮次结束、可合并扩展且以 `kind` 为标签的和类型。`turn/start` 只携带轮次编号；随后已进入的 `user/message` 批次记录其输入，`llm/retry` 则记录请求恢复。
+每次追加都会执行一趟递归处理，对每个嵌套值只读取、校验并复制一次，因此有状态的 getter 无法给校验提供一个值、给存储提供另一个值。非无损 JSON 载荷（BigInt、循环、稀疏数组、`-0`、特殊原型）会在追加位置被拒绝，先于任何后端刷新。表层事件还会校验标记形态、被引用的源事件 seq，以及替换的完整遮蔽节点覆盖。
 
-被中断的实时轮次以 `{ kind: 'aborted', reason: AgentCancelCause }` 结束，在持久 transcript 中保留类型化取消原因。持久化会将受支持旧格式中的粗粒度中止结果导入为 `{ kind: 'aborted', reason: { kind: 'legacy' } }`，因为该记录没有保留调用方。轮次失败携带 `{ kind: 'error', error }`；只有崩溃恢复会合成 `{ kind: 'interrupted' }`。
+### 派生历史
 
-每个 `SessionEvent` 都有三个可选顶层字段（结构元数据）：
+`deriveMessages()` 把每个 surface 节点的投影缓存一次，每次调用都返回共享、深度冻结消息之上的新数组；三种 surface 事件类型（`user/message`、`assistant/message`、`tool/result`）各自投影自己的消息种类——user 内容原样、带提供方与模型的组装 assistant 消息，或 user 角色的工具结果。surface 重写会重建投影——不存在原始日志回退，因此 surface 是派生历史的唯一来源。
 
-- `sourceEventSeqs?: number[]`：被引用为来源的较早事件 seq（例如 `assistant/message` 引用的 `assistant/chunk` seq，或压缩替换条目引用的已遮蔽条目）。对于 `assistant/message`，存在的 `[]` 表示已知提供方流为空；省略则表示旧版或外部事件没有记录源流。其他 surface 事件若有此字段，则要求非空列表。
-- `surfaceOp?: SurfaceOp`：事件进入 surface 的方式。非 surface 事件（边界、分片、用量、错误）不含该字段。
-- `ignorable?: true`：标记读取器在不认识事件类型时可以安全跳过该事件；缺失表示必需，不认识的事件类型会使会话重建被拒绝（[机制](../../../.agents/notes/implemented/architecture/2026-08-10-session-log-version-mechanism.zh.md)）。
+### 请求头
 
-### 元数据类型（`types.ts`）
+循环在每个循环实例边界及变更时记录完整规范 `request/header` 快照（调用配置、适配器默认值、渲染后的系统提示词、组装后的工具 schema）；`foldRequestHeader(events)` 通过选择最新快照来重建它，使每个对话请求都成为日志的纯函数。路由元数据（`request/context`）是独立的已记录状态，仅在提供方、模型或容量变化时追加。
 
-- `SessionHeader`：会话元数据，在发布为 `Session.header` 时写入一次；脱离和深冻结保证运行时不可变：`{ version, id, createdAt, cwd?, parentSession?, seedLength?, delegationDepth? }`。持久化 loader 可返回相同数据类型的可变脱离副本。该类型与 `SessionId` 一同归此包所有，因为 `Session.header` 以它为类型；持久化后端只是重新导出而不拥有它，否则会形成包循环依赖。
+</details>
 
-### 扩展点
+-----
 
-- 持久化插件：订阅 `session/event`（延后写入），并在 `session/flush`（受等待）及 fiber dispose（资源释放）时排空。持久后端读取日志并重新加载到实时会话；这类后端会把元数据约定（`SessionHeader`、`session.header`）与日志一同存储。
-- 回放／fork：`create(id, { seed })` 校验并冻结连续的当前格式日志，再重建 surface；请求头必须包含提供方／模型，assistant 消息必须包含提供方／模型溯源信息。持久化层在构造该当前格式 seed 前负责读取兼容性处理。`fork(source, boundary?, childSessionId?)` 选择已完成轮次前缀并记录谱系。
-- 压缩：`dsh-compaction-basic` 为摘要检查点追加一个替换用 `user/message`，而 `dsh-compaction-tool-result-pruner` 追加仅修改内容的 `tool/result` 替换。工具配对边界策略及其缓存归 [`dsh-compaction` seam](../../compaction/compaction/README.zh.md) 所有；此包拥有有序 surface 成员关系、替换校验与 `replaceGeneration`。

-System prompt assembly registry. Plugins contribute ordered sections, tool schemas, and named variables. The loop assembles once per step and renders the result as the complete model prompt. This plugin owns the static harness identity and global deployment persona; an agent-scoped persona shadows the global default.
+## Summary
 
-## Config
+`dsh-system-prompt` assembles the system prompt and tool schemas the model receives before each step. Plugins contribute ordered prompt sections, dynamic runtime context, tool-schema providers, and named variables; the loop calls `assemble()` once per step and renders the result into the complete model prompt. The package provides the fixed harness identity and the global deployment persona, while an agent-scoped contribution shadows the global default for one agent. Config controls the harness identity opener, dynamic runtime context, the deployment persona, and an explicit model-facing tool order. Choose it when you need to add a prompt section, a prompt variable, or a tool-schema source — it is the assembly point all model-facing prose flows through.

+## Use this package
+
+Mount `dsh-system-prompt` wherever agents run: it provides `ctx.systemPrompt`, the registry every prompt contribution lands in. Contributions are scoped — registering through `agent.ctx` affects that agent alone and shadows a same-named global.
+
+### Configure the prompt
+
+The config owns the fixed opener, runtime context, deployment persona, and tool order; everything else comes from registered contributions.
+
+```yaml
+- name: '@deepseek-ai/dsh-system-prompt'
+  config:
+    includeHarnessIdentity: true
+    includeRuntimeContext: true
+    persona: 'You are the deployment assistant.'
+    toolOrder: ['<unlisted-tools>']
+```
+
+| Field | Default | Meaning |
 |---|---|---|
 | `includeHarnessIdentity` | `true` | Include the fixed `You are an AI agent powered by DeepSeek Harness.` first-party opener at order −1000. Set false only when a compatibility deployment owns the complete system prompt. |
-| `includeRuntimeContext` | `true` | Include ordered dynamic contexts in assembly. When false, context providers are not evaluated and contexts added by `system-prompt/assemble` listeners are discarded after the waterfall; other services and their enforcement remain active. |
-| `persona` | `''` | The global deployment-persona default: the ONE config-authored prompt fragment, rendered as the order-0 `deployment:persona` section unless an agent-scoped contribution shadows it. A template — complete `{{…}}` groups are interpreted strictly against the registered variables (the shipped loop registers `{{model}}`/`{{cwd}}`), with no escape syntax for literal braces yet. Empty ⇒ the section is dropped at render. |
-| `toolOrder` | — | Explicit model-facing tool order, as a list of `ToolSchema.name`s with one `'<unlisted-tools>'` rest entry (`TOOL_ORDER_REST`): listed tools take their listed position, unlisted tools land at the rest entry in lexicographic name order. Absent ⇒ plain lexicographic name order. Applied to the collected tools BEFORE the `system-prompt/assemble` waterfall — like the sections' `order` sort, it canonicalizes what the registry contributed (registration order is a plugin-load artifact), and a waterfall listener that mutates the list owns the determinism of what it emits. Misconfiguration fails loud: a list without exactly one rest entry, or with duplicates, throws at load; a listed name with no registered tool rejects every `assemble()`; a tool provider returning the reserved rest-entry name also rejects. Under the shipped loop the turn fails before any model request. Why a central list and not per-plugin weights: [Explicit model-facing tool order](../../../.agents/notes/implemented/feature/2026-07-06-explicit-tool-order.md). |
+| `includeRuntimeContext` | `true` | Include ordered dynamic runtime context in assembly |
+| `persona` | `''` | The global deployment-persona prompt fragment, rendered at order `0` |
+| `toolOrder` | — | Explicit model-facing tool order with one `'<unlisted-tools>'` rest entry |
 
-## Service: `SystemPrompt` (ctx key: `systemPrompt`)
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-system-prompt) is the exhaustive source for every accepted field. A `toolOrder` list without exactly one rest entry or with duplicates fails at load; a listed name with no registered tool rejects every `assemble()`.
 
-### Public API
+### Contribute a prompt section
 
-- `ctx.systemPrompt.section(section: PromptSection): () => void` Contribute a section. The layer is the calling context's scope: `agent.ctx` contributes to that agent alone, shadowing a same-named global section there. Sections sort by ascending order, then code-unit name for equal orders. A `complete: true` section becomes the exact complete prompt after the assembly waterfall; more than one effective complete section rejects assembly. Duplicate names within one layer and non-finite orders throw. Disposed with the calling fiber.
-- `ctx.systemPrompt.context(context: PromptContext): () => void` Contribute ordered dynamic context for the calling scope. Providers are evaluated for each eligible assembly and become a sourced runtime-context snapshot in model history under the shipped loop.
-- `ctx.systemPrompt.suppressRuntimeContext(): () => void` Suppress every dynamic-context contribution for the calling scope. Multiple registrations compose independently; disposing the returned effect restores context when no suppressor remains.
-- `ctx.systemPrompt.tools(provider: (context: AssembleContext) => ToolProviderResult): () => void` Contribute tool schemas, evaluated at each assembly with that assembly's context. `ToolProviderResult` = `{ schemas, knownNames? }`: `schemas` is the post-restriction visible set; `knownNames` is the pre-restriction universe used by `toolOrder`. A provider must not return a schema named `TOOL_ORDER_REST`. Scoped providers are consulted only for their scope's assemblies. Disposed with the calling fiber.
-- `ctx.systemPrompt.variable(name: string, provider: (context) => string | undefined): () => void` Contribute a prompt variable, referenced from section text as `{{name}}`. Scoped variables shadow a same-named global for that agent. Duplicate-in-layer or unreferenceable names throw; `undefined` means "no value for this assembly". Disposed with the calling fiber.
-- `ctx.systemPrompt.assemble(context?: AssembleContext): Promise<PromptAssembly>` Assemble the prompt for one caller: the global layer merged with `context.scope`'s layer, with tool schemas detached before the transform waterfall. Runs through the scope-filtered `system-prompt/assemble` waterfall, then restores an effective complete section as the sole prompt section and enforces any active runtime-context suppressor. An optional `context.signal` explicitly controls this assembly request; providers and listeners may cooperate with it but must not retain it for another turn. Rejects for multiple complete sections, when a configured `toolOrder` names a tool outside the providers' `knownNames` universe, or when a provider returns the reserved rest-entry name.
+Sections carry static or context-resolved text with an `order`; they are concatenated in ascending order and equal orders use code-unit name order. `FIRST_PARTY_SECTION_ORDER` assigns sparse, unique positions to repository-owned sections, while external sections may use any finite order. A `complete: true` section becomes the exact complete prompt after assembly; more than one effective complete section makes assembly fail.
 
-### Live events
+```text
+ctx.systemPrompt.section({
+  name: 'tool:bash',
+  order: 100,
+  text: 'Prefer bash for file and process operations.',
+})
+```
 
-`system-prompt/assemble` is authoritative for ordinary sections; a complete section is the final prompt constraint applied after the waterfall. Listeners that replace entries must preserve any active Code Mode or structured-output protocol. Use [`ToolRuntime.restrict()`](../tools/README.md) when filtering must stay aligned across presentation, lookup, and execution. Registry-change notifications are unfiltered. The generated region of [system-prompt.md](../../../docs/subsystems/system-prompt.md#cordis-surface) owns signatures and dispatch contracts.
+### Contribute a prompt variable
 
-### Key types
+Variables are referenced from section text as `{{name}}` and resolved at each assembly; scoped variables shadow a same-named global for that agent. The loop supplies `model` and `cwd`; any plugin can register the facts it owns.
 
-- `AssembleContext` — what one `assemble()` call is FOR. Merge-extensible; declares `scope?: ScopeKey` (the layer selector) and `signal?: AbortSignal` (the explicit request control capability) here, while `dsh-agent` declares `agent?: Agent` (the typed DX field — never set without `scope`; use `assembleContextFor(agent, signal)`). Providers must tolerate absent fields because a bare `assemble()` carries an empty, scope-less, signal-less context. `signal` is a request value, not part of the ambient Agent execution frame.
-- `FIRST_PARTY_SECTION_ORDER` — the sparse named allocation for repository-owned sections. Values are unique integers whose adjacent allocated positions differ by at least ten; external sections may use any finite order.
-- `PromptSection` — `{ name, order, text, complete? }`. Sections are concatenated in ascending `order`, with equal values ordered by code-unit `name`. One effective `complete` section suppresses all other sections after cooperative assembly.
-- `PromptAssembly` — `{ sections: AssembledSection[], tools: ToolSchema[], variables: Record<string, string | undefined> }`. Section texts arrive resolved but not yet interpolated; `variables` holds every registered variable resolved against the context. Tool schemas are part of the assembly by design: "what the model is told it can do" is one coherent thing, even though adapters transmit schemas as a separate wire field.
-- `renderPrompt(assembly)` — interpolates `{{variable}}` references in each section, drops empty sections, joins with blank lines. STRICT: an unknown reference (`Object.hasOwn` lookup — prototype names like `{{constructor}}` are unknown), a registered-but-valueless reference, a malformed complete `{{…}}` group, or a `{{` that opens no complete group while a `}}` still follows (`{{{model}}}`) throws — fail loud beats shipping a malformed prompt. A lone `{{` with no `}}` anywhere after it passes through verbatim; substituted values are never re-scanned.
+```text
+ctx.systemPrompt.variable('cwd', ({ agent }) => agent?.session.header.cwd)
+```
 
-Merge-extensible: plugins can declare extra fields on `PromptAssembly` and `AssembleContext` via declaration merging.
+### Contribute tool schemas
 
-### Extension points
+Tool-schema providers are evaluated per assembly and contribute the model-visible `ToolSchema` set; `ToolRuntime` registers itself automatically, so most tools need no manual wiring here. A provider returns the post-restriction visible set plus the pre-restriction name universe used by `toolOrder`.
 
-- Section providers: tool packages own their cross-call guidance (`tool:bash`, `tool:read`, …); this plugin owns `harness:identity` and `deployment:persona`.
-- Variable providers: the agent loop registers `model` and `cwd`; any plugin can register the facts it owns (a future `date`, git state, …).
-- Tool schema providers: `ToolRuntime` registers itself as a tool provider automatically.
-- The [`system-prompt/assemble` waterfall](#live-events): cooperatively mutate or replace the assembly per caller before any complete-section constraint is enforced.
+### Suppress runtime context
 
-Design rationale: [the prompt-variables Agent Note](../../../.agents/notes/implemented/architecture/2026-07-05-prompt-variables-and-tool-guidance-ownership.md) and [the first-party order allocation](../../../.agents/notes/implemented/architecture/2026-08-25-sparse-first-party-prompt-section-orders.md).
+`suppressRuntimeContext()` removes every dynamic runtime-context contribution for the calling scope without disabling the services that own the underlying facts; multiple suppressors compose and the effect restores context when none remains.

+
+This section explains how the package realizes the behavior above; the observable contract is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The package is a registry plus a cooperative assembly pipeline. One `assemble()` call merges the global layer with the requested scope's layer, detaches tool parameters, canonicalizes section order by number and then name, runs the scope-filtered `system-prompt/assemble` waterfall, restores an effective complete section as the sole prompt section, and applies any active runtime-context suppressor. Sections and dynamic contexts are separate inputs: sections become prompt text, while contexts become sourced user-role snapshots in model history under the loop. Tool schemas are part of the assembly by design — "what the model is told it can do" is one coherent thing, even though adapters transmit schemas as a separate wire field.

+### Source map

+| File | Role |

+| [`src/index.ts`](src/index.ts) | Plugin entry: `SystemPrompt` service, config, assembly pipeline, `renderPrompt` |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion |
+
+### Assembly and rendering
+
+Assembly resolves and renders in two stages: `assemble()` returns sections with resolved-but-uninterpolated text, the ordered tool schemas, and every registered variable resolved against the context, while `renderPrompt()` interpolates `{{variable}}` references, drops empty sections, and joins with blank lines — strictly, an unknown reference, a registered-but-valueless reference, or a malformed complete group throws, because a malformed prompt is worse than a loud failure. `toolOrder` canonicalizes the collected tools before the waterfall (registration order is a plugin-load artifact); a waterfall listener that mutates the list owns the determinism of what it emits.
+
+### Scoping
+
+Scoped sections, variables, and tool providers shadow globals for one agent, and the assembly waterfall dispatches scope-filtered. Registry-change notifications (`system-prompt/change`) are deliberately unfiltered because a global change affects every scope.

 ### System prompt
 
 #### What the model sees
 
-By default every assembly starts with the harness identity below, then the configured persona and ordered plugin sections after strict variable interpolation. `includeHarnessIdentity: false` omits only that fixed opener. Empty sections disappear; scoped sections and variables can shadow globals for one agent. The `system-prompt/assemble` waterfall determines the delivered prompt and tool schemas unless one effective section declares itself complete; that exact section then becomes the whole system prompt while the waterfall's contexts, tools, and variables remain. Ordered dynamic contexts are separate from system-prompt sections and become sourced user-role snapshots only when present. `includeRuntimeContext: false` or a scoped suppressor removes all such contexts, including listener additions, without disabling the services that own the underlying policy or state.

+
+
+These limits define when prompt assembly needs special care. They are current package constraints, not a task backlog.
+
 - **Deployment-authored prompt text is config/composition only** — this plugin owns the global persona default, creator plugins may register agent-scoped shadows, and other sections come from the plugin that owns the fact; there is no end-user prompt-editing API.
 - **No escape syntax for literal `{{…}}` braces** — every complete group is interpolated against registered variables; an escape is deferred until a real prompt needs one.
 - **`toolOrder` misconfiguration surfaces at prompt assembly (the first turn), not at boot** — only shape violations throw at config load.

+
+### 设计理念
+
+该包是一个注册表加一条协作式组装流水线。一次 `assemble()` 调用把全局层与所请求作用域的层合并，分离工具参数，先按数值再按名称规范化段顺序，运行按作用域筛选的 `system-prompt/assemble` waterfall（瀑布式事件），把有效的 complete 段恢复为唯一的提示词段，并实施任何活动的 runtime-context 抑制器。段与动态上下文是独立的输入：段成为提示词文本，而上下文在循环下成为模型历史中带来源的 user 角色快照。工具 schema 按设计属于组装结果——「模型获知自己能做什么」是一个连贯整体，尽管适配器把 schema 作为独立 wire 字段传输。

-Tool registry and execution pipeline. Tool plugins register their schemas and executors; the agent loop executes each call through `tools/pre-execute` (the extensible allow/deny gate) → monotonic registered guards → `tools/execute` (an around-dispatch wrapper for timeout/retry/metrics plugins) → `tools/post-execute` (inspect/replace the result, attach context) → the definition-owned `finalizeContent` boundary → the observe-only `tools/result` notification. The registry also owns HOW its tools are presented to the model — its `mode` config selects native function calling, [Code Mode](#code-mode), or both, and one agent shadows that default for itself with `presentAs`.
+## Summary
 
-## Service: `ToolRuntime` (ctx key: `tools`)
+With `dsh-tools`, tool plugins register schemas and executors, and every model tool call runs through a guarded pipeline — allow/deny/ask policy, monotonic guards, around-dispatch wrappers, result inspection, definition-owned content finalization, and a final observe-only notification. The package also controls how tools are presented to the model: its `mode` config selects native function calling, [Code Mode](#code-mode), or both, and one agent shadows that default for itself with `presentAs`. Tool authors use `defineTool` for typed parameter and output schemas, an optional cooperative timeout, parallel-safety classification, and optional UI presentation intents. Choose it as the registry for any capability you want the model to reach — schemas flow into prompt assembly automatically.

-`native` contributes visible tools as function definitions. `code` contributes the reserved `run_code` transport, the generated `tools:sdk` section, and the `tools:code-only` rule stating that only `run_code` may be called directly — which the executor then enforces, resolving a model-direct call naming any other tool to `UNKNOWN_TOOL` before policy runs; `both` contributes both forms and states no such rule, because its native calls do execute. This is the default for agents that declare none of their own — an agent preset selects its own with [`dsh-agent-tool-presentation`](../agent-tool-presentation/README.md). The reserved transport cannot be registered, shadowed, restricted, or removed, and its name is reserved whatever the configured mode, because any agent may select a code mode. Non-native modes require a `ctx.codeRuntime` whose `language` has a registered SDK renderer — TypeScript ships via [`dsh-code-runtime-worker-thread`](../../code-runtime/code-runtime-worker-thread/README.md); a Python renderer is built in and drives any runtime that reports `language: 'python'` (a first-party `dsh-code-runtime-python` backend is delivered separately). A runtime language with no renderer fails prompt assembly loudly, and a `systemPrompt.toolOrder` entry for a tool the mode does not contribute rejects prompt assembly. A `system-prompt/assemble` listener may replace the registry's contributions; its returned assembly is authoritative, so that listener owns preserving a usable Code Mode protocol.

+## Use this package
 
-- `ctx.tools.register(definition: ToolDefinition): () => void` Register a trusted typed same-process definition with a mandatory canonical `output` declaration. The layer is the calling context's scope: a plain plugin context registers globally; an agent's `agent.ctx` registers for that agent alone, shadowing a same-named global tool there. Duplicate names within one layer throw; non-native modes also reject the reserved `run_code` transport name. Missing or unsupported output declarations and a non-positive or non-finite `timeoutMs` fail at registration. The optional synchronous `finalizeContent` callback is snapshotted when a call starts and may replace only final model-facing content after every pipeline outcome is normalized, including an error discovered while materializing another result field. Disposed with the calling fiber.
-- `ctx.tools.presentAs(mode: ToolPresentationMode): () => void` selects this agent's model-facing presentation, shadowing the `mode` config for that agent alone; it throws from a plain context (a process-wide presentation is the config field) and from a second declaration in the same scope. A code mode also registers that agent's own `tools:sdk` section. The catalog is unchanged — `schemas(agent)` still reports the agent's capabilities; only the assembly's tools collapse. Disposed with the calling fiber.
-- `ctx.tools.restrict(filter)` applies an agent-scoped allow/deny mask to global tools and throws from a plain context. The filter is snapshotted at registration; multiple masks intersect and scope-local tools merge afterwards. Deny masks admit later unnamed globals, while allow masks exclude later names. Unknown, local, or reserved names and empty filters reject. This is live visibility composition, not an authority boundary; see the [scope security non-goal](../../../.agents/notes/implemented/architecture/2026-07-08-agent-scope-contexts.md#security-and-authority-are-non-goals).
-- `ctx.tools.get(name: string, scope?: ScopeKey): ToolDefinition | undefined` Resolution as one scope sees it (shadowing applied; a restricted-away global reads as absent). A Host-local presenter consumer passes the calling agent when it must match the definition that executed.
-- `ctx.tools.schemas(scope?: ScopeKey): ToolSchema[]` Schemas of everything the scope can see (without the `execute` functions). The shipped tools' schemas are catalogued in [docs/tool-catalog.md](../../../docs/tool-catalog.md), generated by booting each tool plugin and harvesting this method (see [the tool-schema-catalog Agent Note](../../../.agents/notes/implemented/process/2026-07-02-tool-schema-catalog.md)).
-- `ctx.tools.guard(guard: ToolGuard): () => void` Register a monotonic synchronous execution guard after `tools/pre-execute`: returning a reason denies the call, while `undefined` leaves it unchanged. A plain-context guard applies globally; an `agent.ctx` guard applies only to that agent. Later waterfall listeners cannot turn a guard denial back into permission. Disposed with the calling fiber.
-- `ctx.tools.execute(exec)` losslessly snapshots and freezes arguments, assigns an opaque token, runs the complete policy/dispatch/result pipeline, then independently snapshots the authoritative outcome before final observation. Invalid arguments use the same result path without reaching policy or the body. Around wrappers may replace only `signal`; the registry re-fuses the original caller signal immediately before the body.
-- `ctx.tools.executionMode(exec)` returns `parallel` only when the visible definition's `isConcurrencySafe(exec.arguments)` classifier returns exactly `true`; unknown, hidden, undeclared, invalid, or throwing classifications are exclusive.
+Mount `dsh-tools` wherever agents call tools: it provides `ctx.tools`, the registry every tool plugin registers into and the loop dispatches through. Registering a tool is enough to make it visible — the registry feeds its schemas into the system-prompt assembly automatically.
 
-### Injected services
+### Register a tool
 
-`SystemPrompt` — the registry automatically feeds its tool schemas into the system-prompt assembly via `ctx.systemPrompt.tools()`. The approval seam is consumed opportunistically instead (`ctx.get('approval')`, no static inject): a deployment without it keeps the ask→deny degrade, and the registry stays active either way.
-
-### Cancellation
-
-Cancellation is cooperative and quiescent. Every typed invocation supplies a caller-owned `AbortSignal`; tool bodies receive it as required readonly `exec.signal`, while only `tools/execute` wrappers may temporarily replace the required signal. The registry preserves caller cancellation through replacement and never races away from a started same-process promise. Cancellation before body invocation is `ABORTED_BEFORE_DISPATCH`; cancellation after invocation can replace only a successful outcome with `ABORTED`. A denial, wrapper failure, tool failure, post-policy failure, or timeout-owned `TOOL_TIMEOUT` remains more specific. A pre-aborted entry materializes and freezes arguments, then skips every policy and dispatch phase and publishes one result. Every async tool must observe or forward the signal and settle only after owned work stops. The [tool-cancellation Agent Note](../../../.agents/notes/implemented/architecture/2026-07-19-cooperative-tool-cancellation.md) owns the full contract and hard-termination limit.
-
-### Live events
-
-The live registry pipeline has three transformable waterfalls, then the definition-owned content finalizer, then the observe-only `tools/result` event; registry changes are deliberately unfiltered shared-state notifications. Exact signatures, dispatch modes, scope filtering, and failure containment contracts live in the generated region of [tools.md](../../../docs/subsystems/tools.md#cordis-surface), while the complete ordering is visualized in the generated [tool execution pipeline](../../../docs/tool-execution-pipeline.md). `tools/result` is live; the similarly named `tool/result` is the durable session event the agent loop appends afterwards.
-
-### Key types
-
-- `ToolDefinition` — `ToolSchema` + mandatory `output { schema, render, presentationMeta? }` + `execute(args, exec)`, optional final-content and presentation callbacks, cooperative `timeoutMs`, and optional per-call `isConcurrencySafe(args)` classification. A body returns only the canonical JSON value declared by the output schema and cooperatively stops through `exec.signal`. `finalizeContent(exec, result)` runs exactly once for every normalized result, including failures that bypass post-policy, and can replace only `content`; it must be synchronous and total.
-- `ToolExecutionInput` — the caller-supplied call description: `{ callId, name, arguments, signal, agent?, parent? }`; `signal` is required and readonly, callers may pass an enclosing execution's opaque token as `parent`, and callers never choose the new execution's own token.
-- `ToolExecutionToken` — a fresh branded `Symbol` assigned by the registry. It supports equality correlation only and never crosses a model, log, or worker boundary.
-- `ToolExecution` — the readonly pipeline view: immutable `{ token, callId, name, arguments, signal, agent?, parent? }`; the registry separately retains and re-fuses the original caller signal. `ToolDispatchExecution` is the `tools/execute`-only view whose required signal is mutable, so a wrapper may replace and restore it but cannot delete it. A nested call's `parent` is a `ToolExecutionToken`, not an execution object.
-- `ToolRunContext` — the execution passed to a tool body, extending `ToolExecution` with `deferContext(context)`. It defers one context until the tool's final result reaches the loop — typically a nested-dispatch context ferried by a composite tool, or a fresh plugin-sourced instruction minted by a leaf tool (`tool-goal`'s wrap-up) — even when the tool later throws or cancellation wins; it never injects immediately.
-- `ToolExecutionResult` — discriminated execution-local outcome. Success is `{ isError:false, value:JsonValue, content, meta?, additionalContexts? }`; failure is `{ isError:true, error:{ message, info? }, content, meta?, additionalContexts? }` and has no value. Call identity stays on the immutable `ToolExecution`. The registry snapshots, validates, and freezes the canonical value before rendering, then materializes the durable presentation fields before final observation. `ToolFailure.info` carries an internal `{ name, code }` for a `HarnessError`; `additionalContexts` preserves every deferred or post-execute identified `UserMessage` for the loop's post-result FIFO.
-- `PreToolDecision` — `{kind:'allow'}` | `{kind:'deny', reason}` | `{kind:'ask', reason?}`. Input rewrite is deliberately not offered; `ask` is serviced by [`ctx.approval`](../../interaction/user-approval/README.md) when mounted and otherwise degrades to deny.
-- `PostToolDecision` — accept may replace `content` or `value`, never both, and may attach `additionalContexts`; block turns feedback into a valueless failure. Content replacement preserves the canonical value and metadata. Value replacement is revalidated and rerenders content/metadata. Accept preserves tool-deferred contexts before decision contexts; block discards tool-deferred contexts and exposes only contexts explicitly supplied by the blocking decision.
-- `ToolGuard` — `(execution) => string | undefined`; the returned string is a final monotonic denial reason evaluated after the reorderable pre-execute waterfall and before dispatch.
-- `ToolCallView` / `ToolResultView` — provider-neutral `card`-tagged values returned by the retained Host-side `presentCall` / `presentResult` extension (see "Host presentation descriptors"). The built-in Web Client does not consume these values.
-
-### Extension points
-
-- Tool plugins call `ctx.tools.register()` — schemas flow into the assembly automatically.
-- `tools/pre-execute` is the reorderable allow/deny/ask gate; `ctx.tools.guard()` adds monotonic owner policy after it.
-- `tools/execute` wraps normalized canonical dispatch for timeout, retry, or metrics. Wrappers may replace only the operational signal; a wrapper-authored success is normalized through the resolved tool's output declaration. Each canonical result belongs to one immutable dispatch token, so a cached result from another call or tool is revalidated under the active declaration.
-- `tools/post-execute` may replace presentation content, replace the canonical value, block with feedback, or attach ordered contexts. A definition's optional `finalizeContent` then owns its last content-only invariant across normal results and outer pipeline failures; `tools/result` observes the immutable final outcome. Content replacement is not a confidentiality boundary: block or replace the value when programmatic consumers must not receive it.
-- Exact signatures and ordering live in the generated region of [tools.md](../../../docs/subsystems/tools.md#cordis-surface) and [pipeline](../../../docs/tool-execution-pipeline.md).
-- MCP servers: one plugin per server, discover tools, call `ctx.tools.register()` with the server's schemas.

+`defineTool` builds a typed tool definition: a model-facing name, description, and parameter schema, a canonical output declaration, and an `execute` body that returns only the declared JSON value. Model arguments are validated before execution; invalid input becomes a normal error result.

It supports `string`, `number`, `integer`, `boolean`, `null`, `array`, `object`, author-only `json`, and exact-one `oneOf`; scalar `enum`/`const` values are type-correct. Every explicit DSL object declares `additionalProperties: true | false`, while the implicit parameter root and raw JSON Schema keep the standard open default. Schema records accept only own enumerable string keys, and schema arrays must be dense ordinary arrays. Compilation, validation, registry detachment, and schema-to-TypeScript rendering use explicit work stacks, so runtime processing of valid deep schemas is memory-bounded rather than call-stack-bounded; `InferValue` preserves exact types through 16 container levels and then falls back to `JsonValue` so TypeScript itself remains stack-safe.
+The unified schema DSL supports `string`, `number`, `integer`, `boolean`, `null`, `array`, `object`, author-only `json`, and exact-one `oneOf`; `InferValue` preserves exact types through 16 container levels before widening to `JsonValue`. A raw JSON Schema (`JsonSchemaNode`) is the wire-level counterpart shared with subagents, workflows, and MCP.
 
-A `defineTool` definition validates model arguments before execution and turns missing required values, wrong primitives, invalid enum members, and nested violations into `ToolArgsError` (`INVALID_ARGS`) for the normal error-result path. It also infers the body return and pure output projectors from `output.schema`; the registry snapshots and validates the returned lossless JSON before presentation. The implicit parameter root is open; an explicit object accepts extra keys only with `additionalProperties: true`, and a closed object with no declared properties accepts only `{}`. Raw JSON Schema objects remain open unless they explicitly set `additionalProperties: false`. Defaults are not applied; open objects without `properties` and arrays without `items` receive only a container type check. Raw-registered tools own input validation but still declare and receive registry-enforced output.
+### Configure the presentation mode
 
-See `defineTool`, `validateArgs`, `ToolArgsError`, `ValueSchemaSpec`, `ParameterSchemaSpec`, `InferValue`, `InferArgs`, `valueSchemaSpecToJsonSchema`, and `parameterSchemaSpecToJsonSchema` in the public API for details.
+The `mode` config decides what the model sees: `native` (every visible schema), `code` (only `run_code` plus a generated SDK), or `both`.
 
-Optional `timeoutMs` must be positive and finite; it is policy metadata, not model-visible schema.
+```yaml
+- name: '@deepseek-ai/dsh-tools'
+  config:
+    mode: native
+```
 
-Optional `isConcurrencySafe(args)` receives typed, softly validated arguments. Exact `true` permits concurrent dispatch/body execution; invalid input and all other outcomes remain exclusive. Opted-in bodies do not mutate parent-owned state, and shared-state races must commute or fail closed. The [parallel tool-call Agent Note](../../../.agents/notes/implemented/feature/2026-07-10-parallel-tool-call-execution.md) owns the full safety contract.
+| Field | Default | Meaning |
+|---|---|---|
+| `mode` | `native` | How visible tools are presented to the model: `native`, `code`, or `both` |
+| `maxParallelSubCalls` | `10` | Concurrency cap for a `run_code` program's overlapping sub-calls; `1` restores strictly serial dispatch |
 
-### Enforced raw JSON Schema subset
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-tools) is the exhaustive source for every accepted field. Non-native modes require a composed `ctx.codeRuntime` whose language has a registered SDK renderer; an agent preset selects its own presentation with [`dsh-agent-tool-presentation`](../agent-tool-presentation/README.md), and one agent can shadow the default with `presentAs(mode)`.
 
-`JsonSchemaNode` is the raw counterpart shared by tool outputs, Code Mode generation, subagents, and workflows. It permits any JSON root, an annotation-only unconstrained JSON node, and exact-one `oneOf`; annotations must remain lossless JSON. `assertSupportedJsonSchema()` rejects unsupported constructs, while `validateJsonSchemaValue()` returns path-qualified violations. Subagents and workflows retain their caller-defined object-root requirement through `assertObjectJsonSchema()` and `ObjectJsonSchema`, not through a limitation in the shared vocabulary.
+### Restrict tools per agent
+
+`ctx.tools.restrict(filter)` applies an allow or deny mask to the global tools one agent inherits; masks intersect, scoped registrations stay visible, and the restriction lifts when disposed. `ctx.tools.get(name, scope)` resolves a tool as one scope sees it. A Host-local presenter consumer passes the calling agent when it must match the definition that executed. `ctx.tools.schemas(scope)` returns the visible schemas without the `execute` functions.
+
+### Enforce policy on calls
+
+`ctx.tools.guard(guard)` registers a monotonic synchronous guard after the extensible `tools/pre-execute` waterfall: a returned reason denies the call, and no later listener can turn that denial back into permission. The pipeline's events give plugins more control — `tools/pre-execute` decides allow/deny/ask, `tools/execute` wraps dispatch for timeout or retry, `tools/post-execute` inspects or replaces the result, and `tools/result` observes the frozen final outcome.
 
 ### Host presentation descriptors
 
-Tools may retain pure `presentCall()` and `presentResult()` render intents for Host-local consumers:
+A tool can retain pure `presentCall()` and `presentResult()` methods for Host-local consumers. The built-in Web Client does not consume those values. It selects a renderer through `tool.call.toolview` and derives card props from raw call arguments, result content, failure state, and persisted metadata. The [Client-derived presentation decision](../../../.agents/notes/implemented/architecture/2026-08-23-client-derived-tool-presentation.md) owns this transport split.
 
-- Call views are `{ card: 'generic', title, kind?, rawInput?, content?, locations? }`, `{ card: 'terminal', title, description?, cwd? }`, or `{ card: 'diff', title, diffs, locations? }`.
-- Result views are `{ card: 'generic', title?, content? }`, `{ card: 'terminal', title?, output?, exitCode?, signal? }`, `{ card: 'diff', title?, diffs }`, `{ card: 'search', shape, title?, truncated, total, … }` (a completed discovery search — grouped-by-file matches for `shape: 'matches'` (grep) or a flat path list for `shape: 'paths'` (glob), with `truncated`/`total` so a UI never presents a capped result as complete; the view carries no result text and a search has no `card: 'search'` call-time analogue), `{ card: 'read', title?, path, offset, lines, totalLines, lang?, content? }` (a completed file read → a line-numbered, optionally syntax-highlighted code view; `offset` is the 1-based first line the window requested, kept even when `lines` is empty; `lines` is `{ number, text }[]` keeping each file line number, and `content` is the envelope-stripped text a UI without read support falls back to), or `{ card: 'web', kind: 'search' | 'fetch', title?, … }` (a completed web retrieval; the `kind` arms carry the structured search sources or the fetch summary, and a UI without the `web` capability falls back to the raw result content).
+-----
 
-Returning `undefined` selects generic fallback for a consumer that invokes the presenter. Presenters depend only on their arguments and the durable result so a consumer can use them during live streaming or log replay. `output.presentationMeta(args, value)` derives JSON metadata for direct top-level calls; that metadata persists with `tool/result` and is available both to `presentResult` and to clients that derive their own presentation, while the canonical value itself remains execution-local and is never replayed. Nested Code dispatches do not compute metadata. `defineTool` soft-validates older logged arguments and returns `undefined` on mismatch. Session Remote does not invoke or transport these presenters: the built-in Web Client selects its renderer through `tool.call.toolview` and derives card props from raw call arguments, result content, failure state, and persisted metadata. `dsh-tool-bash` and `dsh-tool-fs` remain reference presenter implementations; the [canonical-output Agent Note](../../../.agents/notes/implemented/architecture/2026-07-20-canonical-tool-output-contract.md) owns the value/presentation split, the [render-intent Agent Note](../../../.agents/notes/implemented/architecture/2026-07-02-tool-render-intent-union.md) owns the retained card vocabulary, and the [Client-derived presentation decision](../../../.agents/notes/implemented/architecture/2026-08-23-client-derived-tool-presentation.md) owns the Web transport split.

+
+This section explains how the package realizes the behavior above; the observable contract is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The registry holds typed `ToolDefinition`s in scoped layers and projects them onto the model-facing `ToolSchema` set at request time — `output`, `execute`, `finalizeContent`, `timeoutMs`, and presentation callbacks never leak onto the wire. Every call runs a fixed pipeline: `tools/pre-execute` (extensible allow/deny/ask) → registered monotonic guards → `tools/execute` (around-dispatch wrappers) → `tools/post-execute` (inspect/replace, attach context) → definition-owned `finalizeContent` → the observe-only `tools/result` event. Only the `tools/execute` view may replace the required signal, and the registry re-fuses the caller signal before the body.

+
+### Execution and cancellation
+
+Each typed invocation materializes and freezes parsed arguments, assigns an opaque correlation token, and runs policy and dispatch. Cancellation is cooperative and quiescent: every tool body receives the caller-owned `exec.signal` and must observe it; cancellation before body invocation is `ABORTED_BEFORE_DISPATCH`, after invocation it replaces only a successful outcome with `ABORTED`. Denials, wrapper failures, tool failures, post-policy failures, and timeout-owned `TOOL_TIMEOUT` remain more specific. Unknown and throwing tools become structured errors (`UNKNOWN_TOOL`), so a call fails without ending the turn.
 
 ### Code Mode
 
-Under `code` or `both`, the registry exposes the reserved `run_code` transport and a deterministic SDK for the current scope, generated in the loaded runtime's language — the registry selects the renderer by `ctx.codeRuntime.language` (`typescript` → the TypeScript SDK below, `python` → the Python SDK). The SDK declares exact per-tool argument and canonical-output types for every visible tool (`ToolArgsMap`/`ToolOutputMap` in TypeScript, named `TypedDict`s in Python), and each binding resolves to the tool's canonical JSON value. Each lossless-JSON binding call re-enters the complete tool pipeline under the native scheduling contract (concurrency-safe calls may overlap up to `maxParallelSubCalls`; exclusive calls run alone as ordering barriers) with logged correlation to the outer call. Denials and other failed results reject with the real program-visible `ToolCallError` carrying only `toolName` and `message`; Native content and internal error codes stay outside the Code contract. The program's outer logs and return value re-enter model context; when a successfully settled sub-call's final Native content contains an image, the bridge also defers that complete ordered content through the parent result so the image is not lost behind the JSON-only binding. Final post-execute blocking or content replacement is authoritative. Ordinary side effects are not rolled back, and sub-call `additionalContexts` are deferred through the parent result to preserve call/result adjacency. Run settlement aborts and drains outstanding bindings; runtime failures surface as `CodeRunFailedError`.
+Under `code` or `both`, the registry exposes the reserved `run_code` transport plus a deterministic SDK generated in the loaded runtime's language. Each SDK binding call re-enters the complete tool pipeline with logged correlation to the outer call, scheduled through a per-run pool that reuses the native concurrency contract. Under `code` alone, a model-direct call naming any other visible tool resolves to `UNKNOWN_TOOL` before policy — the announced surface and the callable surface stay the same. Intermediate binding values are execution-local; only the outer `run_code` result has a hard size cap. The [executor-collapse note](../../../.agents/notes/implemented/bug-fix/2026-08-07-code-mode-executor-collapse.md) owns the collapse contract.
 
-Under `code` — not `both` — the transport is also the only entry the model may use: a model-direct call naming any other visible tool resolves to `UNKNOWN_TOOL` at execution creation, before `tools/pre-execute`, approval `ask`, and guards, so nothing observes or approves a call that can only fail. The denial names the route back (`only \`run_code\` is callable directly — call \`<name>\` from inside a \`run_code\` program instead`), because the same prompt declares that tool and a bare `unknown tool` reads as a broken deployment. SDK sub-dispatches carry the outer execution's `parent` token and are exempt, so programs keep every binding the SDK declared. See the [executor-collapse note](../../../.agents/notes/implemented/bug-fix/2026-08-07-code-mode-executor-collapse.md), the [Code Mode foundation](../../../.agents/notes/implemented/feature/2026-06-15-code-mode.md), [typed-return contract](../../../.agents/notes/implemented/feature/2026-07-20-code-mode-typed-tool-returns.md), and [code-runtime seam](../../code-runtime/README.md). Try `pnpm run demo:code-mode`.
+<a id="extension-points"></a>
+### Extension points
 
-- **The SDK section** (`tools:sdk`, first-party order 5000): a lazy prompt section regenerating the language-appropriate SDK text at each assembly. In the TypeScript flavor it emits `JsonValue`, exact `ToolArgsMap` / `ToolOutputMap`, `ToolName`, the `ToolCallError` declaration, and a mapped `tools` namespace for the calling scope's visible end capabilities (exotic names via quoted keys), plus fixed usage instructions; the Python flavor (`ctx.codeRuntime.language === 'python'`) emits the equivalent named `TypedDict`s and a `tools` object with matching usage instructions. Deterministic — lexicographic tool order, byte-identical text for an unchanged tool set (prefix-cache-friendly). Both codegens are exported and never throw during prompt assembly: `jsonSchemaToTs` handles every unified schema construct and degrades unsupported raw constructs to `unknown`; `jsonSchemaToPy` does the same, degrading to `Any` (and a whole object to `dict[str, Any]` when a field name is not a legal `TypedDict` attribute, or whenever it is called outside the SDK render, which supplies the naming context a `TypedDict` declaration needs).
-- **The dispatch bridge** (`run_code`'s execute): every binding call is snapshotted as lossless JSON before dispatch, scheduled through a per-run pool that reuses the native concurrency contract — calls start strictly in submission order, consecutive `isConcurrencySafe` calls overlap up to the validated `maxParallelSubCalls` config (default 10; `1` restores serial dispatch), and an exclusive-classified call drains the pool, runs alone, and bars later calls — given the outer execution's opaque token as `parent`, and run through the complete pre-execute → guards → execute → post-execute → result pipeline. A success returns the final canonical value after policy; a failure reaches the worker as one message and becomes `ToolCallError(toolName, message)`. Each started sub-call logs a `tool/code-dispatch-start` event (deterministic id `<parent>:code:<n>`, numbered by submission) at pipeline entry and settles with one `tool/code-dispatch` event carrying the complete model-facing `content`/`isError` outcome (the `tool/result` vocabulary, so UIs render sub-calls through the native path — the pair's `time` fields carry per-sub-call timing); a queued call abandoned by run settlement logs neither. `deriveMessages()` surfaces neither event nor persists the canonical value. Token correlation lets commit-style observers defer an inner success until the final `run_code` result without exposing the live outer execution; ordinary tool side effects are not rolled back. Every sub-call `additionalContexts` entry and every successful final content sequence containing an image is deferred through the outer `ToolRunContext` in dispatch order; the loop appends those contexts only after the parent `run_code` result, preserving adjacency and source attribution even when the program later fails.
-- **Settlement discipline**: the bridge owns a run-scoped abort that follows the outer signal in and fires when the run settles for any reason, so a budget expiry aborts an in-flight sub-tool instead of orphaning it; the bridge then drains its queue BEFORE returning, so every `tool/code-dispatch` lands inside the open turn. A failed run throws `CodeRunFailedError` (`code: 'CODE_RUN_FAILED'`, message = the failure kind + captured logs), which the pipeline converts to a structured `isError` the model self-corrects from.
-- **Result size**: intermediate binding values cross the worker process whole and have no per-binding byte cap. `run_code` returns canonical `{ logs: string[], result?: JsonValue }`; strings render raw, every other present JSON root renders through a stack-safe pretty JSON traversal whose total indentation is capped at ten characters (deeper subtrees stay compact), `null` remains explicit, and absent `result` means the program returned `undefined`. The worker's configurable `maxOutputBytes` (default 64 MiB) applies only to the combined serialized outer log-array, completion-value, or failure-message payloads; fixed result-envelope syntax and presentation whitespace are outside that limit. Invalid and over-limit completions fail explicitly, and only this outer result is eligible for ordinary spill.
+Tool plugins call `ctx.tools.register()` and their schemas flow into prompt assembly automatically. `tools/pre-execute` is the reorderable allow/deny/ask gate; `ctx.tools.guard()` adds monotonic owner policy after it; `tools/execute` wraps normalized canonical dispatch for timeout, retry, or metrics; `tools/post-execute` may replace content or value, block with feedback, or attach ordered contexts; `tools/result` observes the immutable final outcome. MCP servers discover tools and register them with the server's schemas.
 
-### Parallel execution
+</details>
 
-The agent loop groups consecutive `parallel` calls into a bounded rolling pool and treats each `exclusive` call as an ordering barrier. Only dispatch/body overlaps; policy, durable results, and context retain model order. Code Mode bindings reuse the same classification through the bridge's own pool. The [parallel tool-call Agent Note](../../../.agents/notes/implemented/feature/2026-07-10-parallel-tool-call-execution.md) owns the shipped declarations and rationale.

 - **Caller-defined subagent and workflow structured outputs remain object-rooted** — this is a consumer-level guard; the shared schema vocabulary and tool outputs support every JSON root.

-`native` 以函数定义的形式贡献可见工具。`code` 会提供保留的 `run_code` 传输、生成的 `tools:sdk` 段，以及声明「只有 `run_code` 可被直接调用」的 `tools:code-only` 规则。执行器随后强制执行该规则：模型直接调用其他任何工具时，会在策略运行前将该调用解析为 `UNKNOWN_TOOL`；`both` 同时提供两种形式，且不声明该规则，因为其中的原生调用确实可以执行。没有单独声明呈现模式的 agent 默认采用此配置；agent preset 可通过 [`dsh-agent-tool-presentation`](../agent-tool-presentation/README.zh.md) 自行选择呈现模式。不能注册、遮蔽、限制或移除该保留传输，且无论配置何种模式，该名称都是保留的，因为任何 agent 都可能选择 code 模式。非原生模式要求所加载 `ctx.codeRuntime` 的 `language` 有已注册的 SDK 渲染器——TypeScript 经 [`dsh-code-runtime-worker-thread`](../../code-runtime/code-runtime-worker-thread/README.zh.md) 交付；Python 渲染器内置，驱动任何报告 `language: 'python'` 的运行时（第一方 `dsh-code-runtime-python` 后端另行交付）。没有渲染器的运行时语言会导致提示词组装明确失败；如果 `systemPrompt.toolOrder` 条目指向当前模式未贡献的工具，系统会拒绝组装提示词。`system-prompt/assemble` 监听器可以替换注册表贡献；它返回的组装结果具有权威性，因此该监听器负责保留可用的 Code Mode 协议。

+## 使用本包
 
-- `ctx.tools.register(definition: ToolDefinition): () => void`：注册一个受信任、带类型的同进程定义，其中必须包含规范的 `output` 声明。所在层由调用上下文的作用域决定：普通插件上下文会全局注册；agent 的 `agent.ctx` 只为该 agent 注册，并在此处遮蔽同名全局工具。同一层内名称重复会抛出；非原生模式还会拒绝保留的 `run_code` 传输名称。缺失或不受支持的输出声明，以及非正数或非有限的 `timeoutMs`，都会使注册失败。可选的同步 `finalizeContent` 回调会在调用开始时纳入快照；在所有流水线结果（包括实体化其他结果字段时发现的错误）规范化之后，它只能替换最终面向模型的内容。该注册会随调用方 fiber 一同 dispose（资源释放）。
-- `ctx.tools.presentAs(mode: ToolPresentationMode): () => void`：为本 agent 选择面向模型的呈现方式，仅对该 agent 遮蔽 `mode` 配置；从普通上下文调用会抛出（进程级呈现方式是那个配置字段），同一 scope 内第二次声明也会抛出。code 类模式还会为该 agent 注册它自己的 `tools:sdk` 段。工具目录保持不变：`schemas(agent)` 仍会报告该 agent 的能力；只有组装结果中的工具列表会按所选呈现方式收束。随调用方 fiber dispose。
-- `ctx.tools.restrict(filter)`：对全局工具应用 agent 作用域的允许／拒绝掩码；从普通上下文调用会抛出。筛选器在注册时创建快照；多个掩码取交集，随后再合并作用域本地工具。拒绝掩码会接纳后来出现且未点名的全局工具，而允许掩码会排除后来出现的名称。未知、本地或保留名称以及空筛选器都会被拒绝。这是实时可见性组合，不是权限边界；参见[作用域安全非目标](../../../.agents/notes/implemented/architecture/2026-07-08-agent-scope-contexts.zh.md#security-and-authority-are-non-goals)。
-- `ctx.tools.get(name: string, scope?: ScopeKey): ToolDefinition | undefined`：返回指定作用域可见的解析结果，其中已应用名称遮蔽；被作用域限制排除的全局工具会被视为不存在。需要匹配实际执行 definition 的 Host 本地 presenter 消费方会传入发起调用的 agent。
-- `ctx.tools.schemas(scope?: ScopeKey): ToolSchema[]`：返回该作用域可见的所有 schema（不含 `execute` 函数）。已交付工具的 schema 收录在 [docs/tool-catalog.md](../../../docs/tool-catalog.zh.md) 中；该目录通过启动每个工具插件并采集此方法的结果生成（参见[工具 schema 目录 Agent Note](../../../.agents/notes/implemented/process/2026-07-02-tool-schema-catalog.zh.md)）。
-- `ctx.tools.guard(guard: ToolGuard): () => void`：在 `tools/pre-execute` 之后注册单调同步执行守卫：返回理由会拒绝调用，返回 `undefined` 则保持原决定。普通上下文守卫全局生效；`agent.ctx` 守卫只对该 agent 生效。后续 waterfall（瀑布式事件）监听器无法将守卫的拒绝重新变为允许。随调用 fiber dispose。
-- `ctx.tools.execute(exec)`：以无损方式快照并冻结参数，分配不透明 token，运行完整的策略／分发／结果流水线，然后在最终观测前独立快照权威结果。无效参数会进入同一结果路径，但不会到达策略或工具主体。环绕包装层只能替换 `signal`；注册表会在进入工具主体之前，立即将调用方的原始信号重新合并到当前信号中。
-- `ctx.tools.executionMode(exec)`：返回 `parallel` 的唯一条件是可见定义的 `isConcurrencySafe(exec.arguments)` 分类器恰好返回 `true`；未知、隐藏、未声明、无效或抛出异常的分类结果均为独占。
+在任何 agent 调用工具的地方挂载 `dsh-tools`：它提供 `ctx.tools`，即每个工具插件注册进去、循环分发所经过的注册表。注册一个工具就足以让它可见——注册表会自动把其 schema 送入系统提示词组装。
 
-### 注入的服务
+### 注册工具
 
-`SystemPrompt`：注册表通过 `ctx.systemPrompt.tools()` 自动将工具 schema 送入系统提示词组装。审批 seam 则在可用时使用（`ctx.get('approval')`，无静态注入）：未部署该 seam 时仍会将询问退化为拒绝，而无论是否存在该 seam，注册表都会保持活动。
-
-### 取消
-
-取消采用协作方式，并等待完全停稳。每次类型化调用都提供由调用方拥有的 `AbortSignal`；工具主体通过必填的只读 `exec.signal` 接收它，只有 `tools/execute` 包装层可以临时替换这个必填信号。注册表会在替换期间保留调用方取消，并且绝不会在已启动的同进程 Promise 尚未结算时提前返回。工具主体调用前发生的取消为 `ABORTED_BEFORE_DISPATCH`；工具主体被调用后发生的取消，只能将成功结果替换为 `ABORTED`。拒绝、包装层失败、工具失败、后置策略失败或由超时机制产生的 `TOOL_TIMEOUT` 仍保留更具体的结果。入口处已中止的调用会实体化并冻结参数，随后跳过所有策略和分发阶段，只发布一个结果。每个异步工具都必须观测或转发该信号，并且只能在其负责的工作停止后结算。[工具取消 Agent Note](../../../.agents/notes/implemented/architecture/2026-07-19-cooperative-tool-cancellation.zh.md) 规定完整约定和强制终止边界。
-
-### 实时事件
-
-实时注册表流水线先经过 3 道可转换的 waterfall，再经过由工具定义持有的内容终结器，最后发布仅供观测的 `tools/result` 事件；注册表变更通知有意不作过滤，并作为共享状态通知发布。确切签名、分发 mode、作用域筛选和失败隔离约定位于 [tools.md](../../../docs/subsystems/tools.zh.md#cordis-surface) 的生成区块，完整顺序则在生成的[工具执行流水线](../../../docs/tool-execution-pipeline.zh.md)中可视化。`tools/result` 是实时事件；名称相近的 `tool/result` 是 agent loop 随后追加的持久会话事件。
-
-### 关键类型
-
-- `ToolDefinition`：`ToolSchema` + 必填的 `output { schema, render, presentationMeta? }` + `execute(args, exec)`，以及可选的最终内容回调、呈现回调、协作式 `timeoutMs` 和逐调用的 `isConcurrencySafe(args)` 分类器。主体只能返回输出 schema 声明的规范 JSON 值，并通过 `exec.signal` 协作停止。`finalizeContent(exec, result)` 对每个规范化结果都恰好运行一次，包括绕过后置策略的失败，并且只能替换 `content`；它必须是同步且对所有输入都有定义的函数。
-- `ToolExecutionInput`：调用方提供的调用描述：`{ callId, name, arguments, signal, agent?, parent? }`；`signal` 必填且只读，调用方可以将外层执行的不透明 token 作为 `parent` 传入，但绝不能选择新执行自身的 token。
-- `ToolExecutionToken`：注册表分配的全新带品牌 `Symbol`。它只支持通过相等性进行关联，绝不会跨越模型、日志或 worker 边界。
-- `ToolExecution`：只读流水线视图：不可变的 `{ token, callId, name, arguments, signal, agent?, parent? }`；注册表会另行保留并重新融合调用方的原始信号。`ToolDispatchExecution` 是仅供 `tools/execute` 使用的视图，其必填信号可变，因此包装层可以替换并还原它，但不能删除它。嵌套调用的 `parent` 是 `ToolExecutionToken`，而不是执行对象。
-- `ToolRunContext`：传给工具主体的执行上下文，在 `ToolExecution` 基础上增加 `deferContext(context)`。它把一条上下文推迟到该工具的最终结果抵达循环时——通常是组合工具转运的嵌套分发上下文，也可以是叶子工具创建的全新插件来源指令（如 `tool-goal` 的收尾注入）——即使工具后来抛出或取消胜出也不例外；该方法绝不会立即注入上下文。
-- `ToolExecutionResult`：带判别标记的执行局部结果。成功形态为 `{ isError:false, value:JsonValue, content, meta?, additionalContexts? }`；失败形态为 `{ isError:true, error:{ message, info? }, content, meta?, additionalContexts? }`，且不含值。调用身份保留在不可变的 `ToolExecution` 上。注册表会在呈现前快照、验证并冻结规范值，随后在最终观测前实体化持久呈现字段。`ToolFailure.info` 携带内部的 `{ name, code }`，用于表示 `HarnessError`；`additionalContexts` 会保留每个通过延迟或 post-execute 加入且带标识的 `UserMessage`，供循环在结果后按 FIFO 顺序处理。
-- `PreToolDecision`：`{kind:'allow'}` | `{kind:'deny', reason}` | `{kind:'ask', reason?}`。该类型有意不提供输入改写；`ask` 在挂载 [`ctx.approval`](../../interaction/user-approval/README.zh.md) 时由它处理，否则退化为拒绝。
-- `PostToolDecision`：接受决定可以替换 `content` 或 `value`（不能同时替换），并可附加 `additionalContexts`；阻止决定会把反馈变成无值失败。替换内容会保留规范值和元数据。替换值会重新验证，并重新呈现内容／元数据。接受决定会先保留工具延迟的上下文，再附加决定上下文；阻止决定会丢弃工具延迟的上下文，只公开阻止决定显式提供的上下文。
-- `ToolGuard`：`(execution) => string | undefined`；返回的字符串是最终单调拒绝理由，在可重排的前置执行 waterfall 之后、分发之前求值。
-- `ToolCallView` / `ToolResultView`：保留的 Host 侧 `presentCall` / `presentResult` 扩展所返回的、提供方无关且带 `card` 标签的值（参见「Host 展示描述」）。内置 Web Client 不消费这些值。
-
-<a id="extension-points"></a>
-
-### 扩展点
-
-- 工具插件调用 `ctx.tools.register()`：schema 会自动流入组装结果。
-- `tools/pre-execute` 是可重排的允许／拒绝／询问门禁；`ctx.tools.guard()` 在其后添加单调的拥有方策略。
-- `tools/execute` 会环绕包装规范化后的规范分发，以支持超时、重试或指标采集。包装层只能替换操作信号；包装层生成的成功结果会根据已解析工具的输出声明进行规范化。每个规范结果属于一个不可变分发 token，因此来自其他调用或工具的缓存结果会根据当前声明重新验证。
-- `tools/post-execute` 可以替换呈现内容、替换规范值、通过反馈阻止，或附加有序上下文。随后，定义可选的 `finalizeContent` 会在普通结果和外层流水线失败中维护其最终、仅涉及内容的不变式；`tools/result` 观测不可变的最终结果。内容替换不是保密边界：当编程消费方不得接收某个值时，应阻止或替换该值。
-- 确切签名与顺序位于 [tools.md](../../../docs/subsystems/tools.zh.md#cordis-surface) 的生成区块和[流水线](../../../docs/tool-execution-pipeline.zh.md)中。
-- MCP 服务器：每个服务器使用一个插件；发现工具后，使用服务器的 schema 调用 `ctx.tools.register()`。
-
-### 类型化工具参数 schema
-
-第一方插件作者可以使用本包导出的 `defineTool()` 辅助函数定义类型化工具参数 schema：
+`defineTool` 构建类型化工具定义：面向模型的名称、描述与参数 schema、规范输出声明，以及只返回所声明 JSON 值的 `execute` 主体。模型参数在执行前被校验；无效输入变成普通错误结果。
 
 ```ts
 import { readFile } from 'node:fs/promises'
@@ -92,51 +57,104 @@ ctx.tools.register(defineTool({
 }))
 ```
 
-统一 schema DSL 使用 `ParameterSchemaSpec` 表示隐式开放参数对象，使用 `ValueSchemaSpec` 表示任意 JSON 值根。它支持 `string`、`number`、`integer`、`boolean`、`null`、`array`、`object`、仅供作者使用的 `json`，以及恰好匹配一个分支的 `oneOf`；标量 `enum`/`const` 值必须符合其声明类型。每个显式 DSL 对象都声明 `additionalProperties: true | false`，而隐式参数根和原始 JSON Schema 保持标准的开放默认值。schema 记录只接受自身可枚举字符串键，schema 数组必须是稠密普通数组。编译、验证、从注册表分离以及 schema 到 TypeScript 的呈现均使用显式工作栈，因此，对有效深层 schema 的运行时处理受内存而非调用栈限制；`InferValue` 在 16 层容器内保留精确类型，之后回退到 `JsonValue`，使 TypeScript 自身也保持栈安全。
+统一 schema DSL 支持 `string`、`number`、`integer`、`boolean`、`null`、`array`、`object`、仅供作者使用的 `json` 与恰好匹配一个分支的 `oneOf`；`InferValue` 在 16 层容器内保留精确类型，之后加宽为 `JsonValue`。原始 JSON Schema（`JsonSchemaNode`）是与 subagent、工作流和 MCP 共享的协议级对应类型。
 
-`defineTool` 定义会在执行前验证模型参数，并把缺失必填值、基本类型错误、无效枚举成员和嵌套违规转换为 `ToolArgsError`（`INVALID_ARGS`），进入普通错误结果路径。它还会根据 `output.schema` 推断主体返回类型和纯输出投影器；注册表在呈现前快照并验证返回的无损 JSON。隐式参数根是开放的；显式对象只有在设置 `additionalProperties: true` 时才接受额外键，而没有声明属性的封闭对象只接受 `{}`。原始 JSON Schema 对象保持开放，除非显式设置 `additionalProperties: false`。系统不会应用默认值；没有 `properties` 的开放对象和没有 `items` 的数组只接受容器类型检查。通过原始方式注册的工具负责输入验证，但仍需声明输出，并由注册表强制校验输出。
+### 配置呈现模式
 
-有关详细信息，请参阅公开 API 中的 `defineTool`、`validateArgs`、`ToolArgsError`、`ValueSchemaSpec`、`ParameterSchemaSpec`、`InferValue`、`InferArgs`、`valueSchemaSpecToJsonSchema` 和 `parameterSchemaSpecToJsonSchema`。
+`mode` 配置决定模型看到什么：`native`（每个可见 schema）、`code`（只有 `run_code` 加一份生成 SDK）或 `both`。
 
-可选的 `timeoutMs` 必须为正数且为有限值；它是策略元数据，不是模型可见的 schema。
+```yaml
+- name: '@deepseek-ai/dsh-tools'
+  config:
+    mode: native
+```
 
-可选的 `isConcurrencySafe(args)` 接收经过软验证的类型化参数。只有确切的 `true` 才允许并发分发／主体执行；无效输入和所有其他结果仍为独占。选择并发的主体不得改变父级拥有的状态；共享状态竞态必须具有交换性，否则必须安全拒绝。[并行工具调用 Agent Note](../../../.agents/notes/implemented/feature/2026-07-10-parallel-tool-call-execution.zh.md) 规定完整安全约定。
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `mode` | `native` | 可见工具向模型呈现的方式：`native`、`code` 或 `both` |
+| `maxParallelSubCalls` | `10` | `run_code` 程序重叠子调用的并发上限；`1` 恢复严格串行分发 |
 
-### 强制执行的原始 JSON Schema 子集
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-tools)是每个受支持字段的穷尽式真源。非原生模式要求已组合的 `ctx.codeRuntime` 且其语言有已注册的 SDK 渲染器；agent preset 通过 [`dsh-agent-tool-presentation`](../agent-tool-presentation/README.zh.md) 自行选择呈现方式，单个 agent 可用 `presentAs(mode)` 遮蔽默认值。
 
-`JsonSchemaNode` 是工具输出、Code Mode 生成、subagent 和工作流共享的原始 JSON Schema 对应类型。它允许任意 JSON 根、仅含注解且不施加约束的 JSON 节点，以及恰好匹配一个分支的 `oneOf`；注解必须保持为无损 JSON。`assertSupportedJsonSchema()` 拒绝不受支持的构造，而 `validateJsonSchemaValue()` 返回带路径的违规信息。subagent 和工作流通过 `assertObjectJsonSchema()` 与 `ObjectJsonSchema` 保留调用方定义的对象根要求，而不是依赖共享词汇的限制。
+### 按 agent 限制工具
+
+`ctx.tools.restrict(filter)` 对单个 agent 继承的全局工具应用允许或拒绝掩码；掩码取交集，作用域注册保持可见，限制在 dispose（资源释放）时解除。`ctx.tools.get(name, scope)` 按一个作用域的视角解析工具。需要匹配实际执行 definition 的 Host 本地 presenter 消费方会传入发起调用的 agent。`ctx.tools.schemas(scope)` 返回可见 schema（不含 `execute` 函数）。
+
+### 对调用实施策略
+
+`ctx.tools.guard(guard)` 在可扩展的 `tools/pre-execute` waterfall（瀑布式事件）之后注册单调同步守卫：返回的理由会拒绝调用，后续监听器无法把该拒绝重新变为允许。流水线事件给插件更多控制——`tools/pre-execute` 决定允许／拒绝／询问，`tools/execute` 为超时或重试包装分发，`tools/post-execute` 检查或替换结果，`tools/result` 观测冻结的最终结果。
 
 ### Host 展示描述
 
-工具可以为 Host 本地消费方保留纯函数 `presentCall()` 和 `presentResult()` 呈现意图：
+工具可以为 Host 本地消费方保留纯函数 `presentCall()` 与 `presentResult()` 方法。内置 Web Client 不消费这些值，而是通过 `tool.call.toolview` 选择 renderer，并从原始调用参数、结果内容、失败状态与持久 metadata 派生 card props。[Client 派生展示决策](../../../.agents/notes/implemented/architecture/2026-08-23-client-derived-tool-presentation.zh.md)负责该 transport 拆分。
 
-- 调用视图为 `{ card: 'generic', title, kind?, rawInput?, content?, locations? }`、`{ card: 'terminal', title, description?, cwd? }` 或 `{ card: 'diff', title, diffs, locations? }`。
-- 结果视图为 `{ card: 'generic', title?, content? }`、`{ card: 'terminal', title?, output?, exitCode?, signal? }`、`{ card: 'diff', title?, diffs }`、`{ card: 'search', shape, title?, truncated, total, … }`（已完成的发现型搜索——`shape: 'matches'`（grep）为按文件分组的匹配，`shape: 'paths'`（glob）为扁平路径列表，配 `truncated`/`total` 使 UI 永不把被截断的结果当作完整结果呈现；该视图不携带结果文本，且搜索没有 `card: 'search'` 的调用时对应视图）、`{ card: 'read', title?, path, offset, lines, totalLines, lang?, content? }`（已完成的文件读取→带行号、可选语法高亮的代码视图；`offset` 是窗口请求的 1-based 起始行，即使 `lines` 为空也保留；`lines` 是 `{ number, text }[]`，保留每一行的文件行号，`content` 是去除读取结果外层封装后的正文，供不支持读取视图的 UI 回退显示）或 `{ card: 'web', kind: 'search' | 'fetch', title?, … }`（已完成的 web 检索；`kind` 各分支携带结构化的搜索来源或抓取摘要，不具备 `web` 能力的 UI 回退到原始结果内容）。
+-----
 
-返回 `undefined` 会让调用 presenter 的消费方选择通用回退。presenter 只依赖其参数和持久结果，因此消费方可以在实时流式输出或日志回放期间使用。`output.presentationMeta(args, value)` 为直接顶层调用派生 JSON metadata；该 metadata 随 `tool/result` 持久化，既可供 `presentResult` 使用，也可供自行派生展示的 Client 使用，而规范值本身仍只存在于执行局部，绝不会回放。嵌套 Code 分发不会计算 metadata。`defineTool` 会软验证旧日志参数，并在不匹配时返回 `undefined`。Session Remote 不调用也不运输这些 presenter：内置 Web Client 通过 `tool.call.toolview` 选择 renderer，并从原始调用参数、结果内容、失败状态和持久 metadata 派生 card props。`dsh-tool-bash` 与 `dsh-tool-fs` 仍是 presenter 参考实现；[规范输出 Agent Note](../../../.agents/notes/implemented/architecture/2026-07-20-canonical-tool-output-contract.zh.md) 规定值／呈现拆分，[呈现意图 Agent Note](../../../.agents/notes/implemented/architecture/2026-07-02-tool-render-intent-union.zh.md) 规定保留的卡片词汇，[Client 派生展示决定](../../../.agents/notes/implemented/architecture/2026-08-23-client-derived-tool-presentation.zh.md) 规定 Web transport 的拆分。

+
+### 设计理念
+
+注册表在作用域层中持有类型化 `ToolDefinition`，并在请求时把它们投影为面向模型的 `ToolSchema` 集合——`output`、`execute`、`finalizeContent`、`timeoutMs` 与呈现回调绝不会泄漏到协议上。每次调用都运行一条固定流水线：`tools/pre-execute`（可扩展的允许／拒绝／询问）→ 已注册单调守卫 → `tools/execute`（环绕分发包装层）→ `tools/post-execute`（检查／替换、附加上下文）→ 由定义持有的 `finalizeContent` → 仅观测的 `tools/result` 事件。只有 `tools/execute` 视图可以替换必填信号，注册表会在调用主体前重新融合调用方信号。

+### 执行与取消
+
+每次类型化调用都会实体化并冻结解析后的参数、分配不透明关联 token，再运行策略与分发。取消采用协作式并等待完全停稳：每个工具主体都收到调用方拥有的 `exec.signal` 且必须观测它；调用主体前的取消为 `ABORTED_BEFORE_DISPATCH`，调用主体后的取消只能把成功结果替换为 `ABORTED`。拒绝、包装层失败、工具失败、后置策略失败与超时产生的 `TOOL_TIMEOUT` 仍保留更具体的结果。未知工具与抛出异常的工具都会变成结构化错误（`UNKNOWN_TOOL`），因此调用会失败而不会结束轮次。
 
 ### Code Mode
 
-在 `code` 或 `both` 模式下，注册表为当前作用域公开保留的 `run_code` 传输和按所加载运行时语言生成的确定性 SDK——注册表按 `ctx.codeRuntime.language` 选择渲染器（`typescript` → 下方的 TypeScript SDK，`python` → Python SDK）。SDK 为每个可见工具声明精确的参数与规范输出类型（TypeScript 为 `ToolArgsMap`/`ToolOutputMap`，Python 为具名 `TypedDict`），每个绑定都会解析为该工具的规范 JSON 值。每个无损 JSON 绑定调用都会在原生调度约定下重新进入完整工具流水线（并发安全的调用最多可重叠 `maxParallelSubCalls` 个；独占调用单独运行并构成排序屏障），并在日志中与外层调用建立关联。拒绝及其他失败结果会以程序实际可见的 `ToolCallError` 形式拒绝，且只携带 `toolName` 和 `message`；Native 内容和内部错误码留在 Code 约定之外。程序的外层日志与返回值会重新进入模型上下文；当成功结算的子调用最终 Native 内容包含图片时，桥接层还会经父结果延后完整有序内容，避免图片被 JSON 专用绑定遮蔽。最终 post-execute 阻止或内容替换具有权威性。普通副作用不会回滚，子调用的 `additionalContexts` 会通过父结果延迟，以保持调用／结果相邻。运行结算会中止并排空尚未完成的绑定；运行时失败以 `CodeRunFailedError` 形式出现。
+在 `code` 或 `both` 下，注册表公开保留的 `run_code` 传输以及按所加载运行时语言生成的确定性 SDK。每个 SDK 绑定调用都会在日志中与外层调用关联，重新进入完整工具流水线，并通过复用原生并发约定的每次运行独有池调度。在纯 `code` 下，模型直呼其他任何可见工具都会在策略之前解析为 `UNKNOWN_TOOL`——通告面与可调用面保持一致。中间绑定值只存在于执行局部；只有外层 `run_code` 结果有硬大小上限。[执行器塌缩 note](../../../.agents/notes/implemented/bug-fix/2026-08-07-code-mode-executor-collapse.zh.md) 拥有该收束约定。
 
-在 `code`（而非 `both`）下，该传输同时也是模型唯一可用的入口：模型直呼其他任何可见工具名，都会在创建执行时、早于 `tools/pre-execute`、审批 `ask` 和 guards 解析为 `UNKNOWN_TOOL`，因此没有任何一方会观察或批准一个注定失败的调用。拒绝信息会给出正确路径（`only \`run_code\` is callable directly — call \`<name>\` from inside a \`run_code\` program instead`），因为同一份提示词刚刚声明过那个工具，只说 `unknown tool` 会被读成部署损坏。SDK 子分发携带外层执行的 `parent` token，不受此限制，因此程序保留 SDK 声明的全部绑定。参见[执行器塌缩 note](../../../.agents/notes/implemented/bug-fix/2026-08-07-code-mode-executor-collapse.md)、[Code Mode 基础](../../../.agents/notes/implemented/feature/2026-06-15-code-mode.md)、[类型化返回约定](../../../.agents/notes/implemented/feature/2026-07-20-code-mode-typed-tool-returns.md)和[代码运行时 seam](../../code-runtime/README.md)。可以运行 `pnpm run demo:code-mode` 试用。

+### 扩展点
 
-- **SDK 段**（`tools:sdk`，first-party 顺序 5000）：一个在组装时求值的提示词段，每次组装都会重新生成与所加载运行时语言相符的 SDK 文本。TypeScript 形态会生成 `JsonValue`、精确的 `ToolArgsMap` / `ToolOutputMap`、`ToolName`、`ToolCallError` 声明，以及映射调用作用域最终可见工具的 `tools` 命名空间（特殊名称使用带引号的键），并附带固定的使用说明；Python 形态（`ctx.codeRuntime.language === 'python'`）发出等价的具名 `TypedDict` 与一个带相同用法说明的 `tools` 对象。其输出具有确定性：工具按字典序排列；工具集合不变时，文本逐字节相同（有利于前缀 cache）。两个代码生成器都已导出，且绝不会在提示词组装期间抛出：`jsonSchemaToTs` 处理统一 schema 的每种构造并将不受支持的原始构造降级为 `unknown`；`jsonSchemaToPy` 同理，降级为 `Any`（当某字段名不是合法的 `TypedDict` 属性时，或在 SDK 渲染之外被调用时——`TypedDict` 声明所需的命名上下文由该渲染提供——整个对象降级为 `dict[str, Any]`）。
-- **分发桥接层**（`run_code` 的 execute）：每个绑定调用都会在分发前快照为无损 JSON，经由每次运行独有、复用原生并发约定的池调度——调用严格按提交顺序启动，连续的 `isConcurrencySafe` 调用最多可重叠经校验的 `maxParallelSubCalls` 配置个（默认 10；设为 `1` 即恢复串行分发），被分类为独占的调用先排空池、单独运行并阻挡其后的调用——以外层执行的不透明 token 作为 `parent`，并经过完整的 pre-execute → guards → execute → post-execute → result 流水线。成功会返回策略处理后的最终规范值；失败以一条消息到达 worker，并成为 `ToolCallError(toolName, message)`。每个已启动的子调用在进入流水线时记录一条 `tool/code-dispatch-start` 事件（确定性 id `<parent>:code:<n>`，按提交顺序编号），并以一条携带完整模型可见 `content`/`isError` 结果的 `tool/code-dispatch` 事件完结（采用 `tool/result` 词汇，因此 UI 会沿原生路径呈现子调用——这对事件的 `time` 字段承载每个子调用的计时）；因 run 结算而被放弃的排队调用两者都不记录。`deriveMessages()` 既不公开这两个事件，也不持久化规范值。token 关联使按提交语义工作的观察器可以延后提交内部调用的成功结果，直到最终 `run_code` 结果确定，而无需暴露进行中的外层执行；普通工具副作用不会回滚。每个子调用的 `additionalContexts` 条目以及每份成功且含图片的最终内容序列都会按分发顺序通过外层 `ToolRunContext` 延迟；循环只在父级 `run_code` 结果之后追加这些上下文，从而保持相邻关系和来源归属，即使程序后来失败也不例外。
-- **结算纪律**：桥接层拥有一个运行作用域的中止机制；该中止会跟随传入的外层信号，并在运行因任何原因结算时触发，因此预算耗尽会中止正在运行的子工具，而不会将其遗留。桥接层随后会在返回之前排空队列，使每个 `tool/code-dispatch` 都落在仍打开的轮次内。失败的运行会抛出 `CodeRunFailedError`（`code: 'CODE_RUN_FAILED'`，message = 失败类型 + 已捕获日志），流水线会将其转换为模型可据以自我修正的结构化 `isError`。
-- **结果大小**：中间绑定值会完整传入 worker 进程，且没有逐绑定字节上限。`run_code` 返回规范的 `{ logs: string[], result?: JsonValue }`；字符串原样呈现，其他所有存在的 JSON 根都通过栈安全的美化 JSON 遍历呈现，总缩进最多为 10 个字符（更深的子树保持紧凑），`null` 保持显式，而缺少 `result` 表示程序返回 `undefined`。worker 可配置的 `maxOutputBytes`（默认 64 MiB）只应用于组合序列化后的外层日志数组、完成值或失败消息载荷；固定的结果封装语法和呈现空白不计入该上限。无效和超限的完成会明确失败，只有这个外层结果可以按常规 spill 机制处理。
+工具插件调用 `ctx.tools.register()`，其 schema 会自动流入提示词组装。`tools/pre-execute` 是可重排的允许／拒绝／询问门禁；`ctx.tools.guard()` 在其后添加单调的拥有方策略；`tools/execute` 为超时、重试或指标包装规范化后的规范分发；`tools/post-execute` 可以替换内容或值、通过反馈阻止，或附加有序上下文；`tools/result` 观测不可变的最终结果。MCP 服务器发现工具后，用服务器的 schema 调用 `ctx.tools.register()`。

 # credentials/ — credentials and authorization
 
 English | [中文](README.zh.md)
 
-The credential capability family separates reference resolution from its provider, and separates both from obtaining a credential that has to be asked for:
+## Summary
+
+The `credentials/` group manages the secret values your configuration refers to by name: store an API key once, reference it from settings or `cordis.yml`, and rotate it without editing any configuration file. It provides the runtime part of the product that stores and looks up secrets (`credentials/`), the default on-machine credential file (`credentials-local/`), and the authorization flow registry (`authorization/`) for credentials that cannot be configured, because getting one means asking a human. A rotated key reaches the very next model request, and a per-run environment override (`DEEPSEEK_API_KEY=… dsh`) always wins over stored values. Secret values never enter configuration files you sync or render — only their names do, and the local file is readable by the same OS user, not by others.

+## Packages
+
+Three packages provide the credential feature: one stores, looks up, and removes secrets at runtime while configuration only names them; the second is the default on-machine store; the third lets plugins obtain credentials that have to be asked for. Their READMEs cover day-to-day use; the subsystem reference owns the exhaustive contracts.
 
 | Package | Role | ctx key |
 |---|---|---|
-| [`credentials/`](credentials/README.md) | Credential-reference and credential-record seam | `ctx.credentials` |
-| [`credentials-local/`](credentials-local/README.md) | Environment and local-file provider | registers `ctx.credentials` |

+| [`credentials-local/`](credentials-local/README.md) | The default on-machine store: a private YAML file, environment overrides win | registers `ctx.credentials` |
 | [`authorization/`](authorization/README.md) | Plugin-owned flows that obtain a credential by asking a human | `ctx.authorization` |
 
-Configuration carries references, not secret values. Consumers resolve those references at their operation boundary; the child READMEs own mutation, precedence, and storage semantics. An authorization flow writes a credential record and is keyed by it, so the two seams meet at the record and nowhere else.

 English | [中文](README.zh.md)
 
-Authorization Service Definition (`ctx.authorization`). Some credentials cannot be configured, only obtained: getting one means a conversation with a human — open this page, paste that code, pick an account. This seam owns that conversation and the lifecycle around it, and never the protocol.
+## Summary
 
-**A flow is a plugin's knowledge of how to get its own credential.** It is registered under the [`CredentialKey`](../credentials/README.md#two-key-spaces-two-questions) it writes, so a flow says which record it produces and, through that key's scope, which plugin answers for the format inside it. A second authorization protocol arrives as another flow, not as another seam.
+`dsh-authorization` obtains credentials that configuration cannot supply by asking a human: a plugin registers one flow per credential, and a configuration UI or another surface runs an attempt whose notices and questions reach exactly the page that asked. A human signs in with one of the flow's methods, pastes a code, or answers a question; when the flow resolves, its credential record is committed to the `dsh-credentials` store, and an attempt only reports `authorized` when that commit was observed. A refusal or a withdrawn attempt settles as `cancelled` rather than an error, so a surface can tell "the human said no" from "the flow broke". Choose it when a credential must be obtained interactively: it builds on the credential-record half of the credential seam, needs that store mounted, and ships no flows of its own — your plugin registers them.
 
-**The flow owns the write.** `run()` resolving means the record is already committed through `ctx.credentials`; the seam confirms a commit it observed during the attempt — presence alone would let a re-authorization pass a stale record off as fresh — and refuses a flow that resolved without one. Committing inside the flow is what lets a library that persists through its own store adapter stay the single writer instead of being copied back out and written twice.
+## Table of Contents
 
-**The interaction travels with the request, not a registry.** Whoever starts an authorization is the one who can talk to the human about it, so prompts reach exactly the surface that asked and a headless caller supplies an interaction that declines. There is no ambient provider to be absent, and no question about which of two open pages a prompt belongs to.

+
+<a id="use-this-package"></a>
+## Use this package
+
+This package is the part of the product that obtains credentials a human must hand over: a plugin registers the flow that knows how to get its own credential, and any surface can run an attempt and show the human what to do. The common path is explicit — register a flow for each credential your plugin holds, then start attempts from the surface the human is looking at.
+
+### When to use it
+
+Use it whenever a credential can only be obtained by talking to a human — an OAuth-style sign-in, a one-time code, an account pick — and cannot be stored in configuration. If a credential is a fixed key a deployment can supply, store it with the credential seam instead. A headless or ACP composition can mount this package safely: it offers no flows of its own, so nothing asks a human to sign in unless a plugin registered a flow.
+
+### Registering a flow
+
+Your plugin declares one flow per credential it holds, keyed by the `<scope>/<id>` credential record the flow writes — the scope names your plugin, the id names one credential it owns:
 
 ```ts
 import type { Context } from '@deepseek-ai/cordis'
-import { AuthorizationDeclinedError, type AuthorizationSession } from '@deepseek-ai/dsh-authorization'
+import type { AuthorizationSession } from '@deepseek-ai/dsh-authorization'

 ```
 
-One attempt per key at a time. A second caller is refused with `ALREADY_IN_FLIGHT` rather than joined, because the two would be prompting different humans through one flow and the second would be answering questions the first was asked. `inFlight` is on the entry so a surface renders the button disabled instead of discovering this by error.
+A flow declares the credential record it writes, a user-facing label, and the sign-in methods it offers, most preferred first. `run()` talks to the human through the session — one-way notices and questions the flow cannot answer for itself — and must commit the record through `ctx.credentials` before resolving: the seam refuses a flow that resolved without committing. `list()` and `describe()` let a surface show what can be authorized and whether an attempt is running; `dispose()` unregisters the flow and withdraws any attempt still running.
 
-`cancel(key)` exists beside the request's own signal because a request/response transport answers a Cancel button on a second call, holding no handle on the first one's signal. A flow whose registration is disposed mid-attempt is withdrawn the same way: its runner belongs to a plugin that is going away.
+### Running an attempt
 
-An attempt whose caller has already withdrawn never claims the key and never starts the flow — relying on each flow to check its signal before the first await would let one that does not hang holding the key. Validation still runs first, so a caller naming a key or method that does not exist hears about it whether or not it also gave up.
+A surface runs one attempt per credential at a time. The interaction travels with the request rather than living in a registry, so prompts reach exactly the page that asked; a headless caller supplies an interaction that declines. `begin()` reports `{ status: 'authorized' }` when the record was committed and observed during the attempt, and `{ status: 'cancelled' }` when the human declined or the caller withdrew. `cancel(key)` withdraws the running attempt from a second call, for the request/response transport that answers a Cancel button without holding the first call's signal.
 
-A human's "no" is an outcome, not a breakage. An interaction that declines rejects its prompt with `AuthorizationDeclinedError`, and an attempt that fails after a declined prompt settles as `cancelled`, exactly as a withdrawn signal does; any other prompt rejection stays a flow failure that reaches the caller. A notice is fire-and-forget on the same principle, held at the seam: a surface that cannot render one loses the notice, never the attempt.
+### What can go wrong
 
-`authorization/settled (key, settlement)` fires after the key is released, for every terminal outcome. `settlement` adds `failed` to the two statuses `begin()` can return: a failure reaches its own caller as a thrown error, so the event stream is the only place a watcher that did not start the attempt can tell a refusal from a breakage. Listener failures are contained: every listener runs, a throw or rejection is logged without changing the finished attempt's outcome, and only an `INVARIANT`-coded failure rethrows after the rest ran.
+- **A credential with no flow is inert** — `begin()` on a key no flow claims throws `NO_FLOW`; a record left by an uninstalled plugin can be deleted but not re-authorized.
+- **One attempt at a time per credential** — a second `begin()` while one is running throws `ALREADY_IN_FLIGHT`; `inFlight` on the entry lets a UI disable the button up front.
+- **A flow that resolves without committing is refused** — `NOT_COMMITTED`, so `authorized` always means the record is really stored.
+- **Naming a method the flow does not offer throws `UNKNOWN_METHOD`** — naming none runs the flow's first method.
+- **"No" is an outcome, not a breakage** — a declined prompt settles the attempt as `cancelled`, the same as a withdrawn signal; any other failure reaches the caller as a thrown error.
 
-## The interaction vocabulary
+-----
 
-A notice is one-way and never carries a secret: a message, optionally the page the human must open and the code they must enter there. A prompt is a question the flow cannot answer — `text`, `secret`, or `select` — and `secret` differs from `text` only in presentation. A prompt carries its own `signal` so a flow that races a typed code against a browser callback can withdraw the losing question while the attempt continues; the request's signal withdraws the whole attempt instead.
+<a id="understand-the-implementation"></a>
+## Understand the implementation
 
-The vocabulary is deliberately smaller than any one provider's: it describes what a surface must render, so a surface that renders one flow renders all of them.
+<details>
+<summary>Implementation internals — click to expand</summary>
 
+This section explains the design decisions behind the seam and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+- **The seam owns the conversation, never the protocol.** A plugin that knows how to obtain its own credential registers a flow keyed by the record it writes; a second authorization protocol arrives as another flow rather than another seam, and a surface that renders one flow renders all of them.
+- **The flow owns the write.** `run()` resolving means the record is already committed through `ctx.credentials`; the seam confirms a commit it observed during the attempt — presence alone would let a re-authorization pass a stale record off as fresh — and refuses a flow that resolved without one. Committing inside the flow is what lets a library that persists through its own store adapter stay the single writer instead of being copied back out and written twice.
+- **The interaction travels with the request, not a registry.** Whoever starts an authorization is the one who can talk to the human about it, so prompts reach exactly the surface that asked, and a headless caller supplies an interaction that declines. There is no ambient provider to be absent, and no question about which of two open pages a prompt belongs to.
+- **A human's "no" is an outcome, not a breakage.** An interaction that declines rejects its prompt with `AuthorizationDeclinedError`, and the attempt settles as `cancelled`, exactly as a withdrawn signal does; any other prompt rejection stays a flow failure that reaches the caller.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Service Definition: flow registry, one-attempt-per-key lifecycle, interaction routing, commit confirmation |
+| [`src/types.ts`](src/types.ts) | Wire-safe vocabulary: methods, notices, prompts, outcomes, entries |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion: `authorization/settled` always names a released key |
+
+### Lifecycle
+
+One attempt per key at a time. `begin()` validates the key and method, refuses a second attempt for a busy key, and runs the flow with an `AuthorizationSession` that carries the chosen method, a cancellation signal, and the `notify`/`prompt` callbacks routed to the request's interaction. A withdrawn attempt settles immediately even when the flow never reacts to its signal — the orphaned run is left to finish on its own, and a record it still manages to commit is a record the human did authorize. The key is released before `authorization/settled` fires, so a listener that reacts by starting the next attempt is not refused; listener failures are contained on the credentials seam's terms.
+
+### The interaction vocabulary
+
+A notice is one-way and never carries a secret: a message, optionally the page the human must open and the code they must enter there. A prompt is a question the flow cannot answer for itself — `text`, `secret`, or `select` — where `secret` differs from `text` only in presentation. A prompt carries its own signal so a flow that races a typed code against a browser callback can withdraw the losing question while the attempt continues; the request's signal withdraws the whole attempt instead. The vocabulary is deliberately smaller than any one provider's: it describes what a surface must render, so a surface that renders one flow renders all of them.
+
+### Commit confirmation
+
+During the attempt the seam watches `credentials/record-updated` for the flow's key, then after `run()` resolves it re-reads `describeRecord` — confirming the commit happened now, because on a re-auth the record already exists and presence alone would let a stale credential pass as freshly authorized. A flow that resolves without committing, or that deleted its record instead of committing one, throws `NOT_COMMITTED`.

-- **Nothing revokes** — signing out is `ctx.credentials.deleteRecord(key)`, which forgets the local record without telling the issuer. A provider that needs a server-side revoke has no place to declare it yet.

+This Dev Note is working context for maintainers: open questions and undecided directions. It is explicitly non-authoritative — shipped behavior, limits, and accepted rationale live in the sections above, the package code, and the linked Agent Note.
+
+The limitations above name the open directions — resumable attempts, server-side revocation, orphaned-record discovery — each needing its own design and store before landing. The invariant companion is the one load-bearing runtime check: settlement must always find the key released, because a wedged key is indistinguishable from a busy one and only a restart frees it.

-授权 Service Definition（`ctx.authorization`）。有些凭据无法配置，只能获取：拿到它意味着与人对话——打开这个页面、粘贴那个码、选一个账号。本 seam 拥有这段对话及其生命周期，但从不拥有协议本身。
+## 概述
 
-**flow 是某个插件"如何取得自己那份凭据"的知识。** 它以自己写入的 [`CredentialKey`](../credentials/README.zh.md#two-key-spaces-two-questions) 注册，因此 flow 声明了自己产出哪条记录，并通过该键的 scope 声明由哪个插件为记录内部的格式负责。第二种授权协议以另一个 flow 的形式到来，而不是另一个 seam。
+`dsh-authorization` 通过询问人来获取配置无法提供的凭据：插件为每个凭据注册一个 flow，配置 UI 或其他界面发起一次尝试，其 notice 与提问恰好抵达发出请求的那个页面。人用 flow 提供的方法之一登录、粘贴一个码或回答一个问题；flow 结束时，其凭据记录已提交到 `dsh-credentials` 存储，而只有观察到这次提交时，尝试才报告 `authorized`。拒绝或撤销的尝试以 `cancelled` 结算而非报错，因此界面能区分「人说了不」与「flow 出了故障」。当凭据必须交互式获取时选择它：它建立在凭据 seam 的记录半侧之上、需要挂载该存储，且本身不随附任何 flow——由你的插件注册。
 
-**写入由 flow 拥有。** `run()` 返回即表示记录已经通过 `ctx.credentials` 提交；seam 核实的是它在本次尝试期间观察到的提交——只看记录存在与否，会让重新授权把陈旧记录冒充成新鲜的——并拒绝那些返回时没提交记录的 flow。让提交发生在 flow 内部，才能使一个通过自有 store 适配器持久化的库保持为唯一写入方，而不是把凭据复制出来再写第二遍。
+## 目录
 
-**交互随请求传入，而非注册表。** 发起授权的一方才是能与人对话的一方，因此提示恰好抵达发问的那个界面，无头调用方则传入一个直接拒绝的交互实现。这样既不存在"环境提供方缺席"的问题，也不会出现某个提示该归两个已打开页面中哪一个的疑问。

+## 使用本包
+
+本包是产品中负责获取「必须由人交出来」的凭据的部分：插件注册一个知道如何取得自己那份凭据的 flow，任何界面都能发起尝试并向人展示该做什么。常用路径是显式的——为你插件持有的每个凭据注册一个 flow，然后从人正看着的那个界面发起尝试。
+
+### 何时使用
+
+只要凭据只能通过与人对话获得——OAuth 式登录、一次性码、选一个账号——且无法存入配置，就使用它。如果凭据是部署方可以提供的一个固定密钥，请改用凭据 seam 存储它。无头或 ACP 组合也可以安全挂载本包：它本身不提供任何 flow，因此除非插件注册了 flow，否则不会要求人登录。
+
+### 注册 flow
+
+你的插件为它持有的每个凭据声明一个 flow，以该 flow 写入的 `<scope>/<id>` 凭据记录为键——scope 点名你的插件，id 点名它拥有的一条凭据：

 import { credentialKey } from '@deepseek-ai/dsh-credentials'

     const code = await session.prompt({ kind: 'text', message: 'Paste the code' })
-    // Commits the record through ctx.credentials before resolving.
-    await exchange(session.signal)
-    void code
+    const { token } = await exchangeCode(code, session.signal)
+    await ctx.credentials.modifyRecord(key, () => Promise.resolve({ kind: 'grant', payload: { token } }))
   },
 })
 
-ctx.authorization.list()                    // [{ key, label, methods, inFlight }]
-ctx.authorization.describe(key)             // the same entry, or undefined
-await ctx.authorization.begin({             // { status: 'authorized' | 'cancelled' }
-  key,
-  interaction: { notify: () => {}, prompt: () => Promise.reject(new AuthorizationDeclinedError()) },
-})
-ctx.authorization.cancel(key)               // withdraw whatever is running for the key
-dispose()
+ctx.authorization.list()          // every registered flow, with inFlight
+ctx.authorization.describe(key)   // the entry above, or undefined
+dispose()                         // unregister; withdraws any running attempt
 ```
 
-同一个键同时只允许一次尝试。第二个调用方会收到 `ALREADY_IN_FLIGHT` 拒绝而不是被并入：否则两者会通过同一个 flow 向不同的人发问，而第二个人回答的是问给第一个人的问题。`inFlight` 放在 entry 上，界面据此把按钮渲染为禁用，而不是靠报错才发现。
+flow 声明它写入的凭据记录、面向用户的标签以及它提供的登录方法，最优先者在前。`run()` 通过 session 与人对话——单向 notice 与 flow 无法自行回答的问题——并且必须在返回前通过 `ctx.credentials` 提交记录：seam 会拒绝未提交就返回的 flow。`list()` 与 `describe()` 让界面展示可授权的内容以及是否有尝试在运行；`dispose()` 注销该 flow 并撤销仍在运行中的尝试。
 
-`cancel(key)` 与请求自带的 signal 并存，是因为请求/响应式传输要用第二次调用来响应"取消"按钮，而它拿不到第一次调用的 signal。注册在尝试进行中被 dispose 的 flow 也以同样方式撤销：它的执行体属于一个正在离开的插件。
+### 发起一次尝试
 
-调用方在发起前就已撤销的尝试，既不占用该键也不启动 flow——若指望每个 flow 都在首个 await 之前检查自己的 signal，那么没有检查的那个就会占着键一直挂起。校验仍然先执行，因此调用方给出的键或方法不存在时，无论它是否已经放弃都会收到报错。
+每个凭据同时只允许一次尝试。交互随请求传入而非存放在注册表中，因此提问恰好抵达发问的那个页面；无头调用方传入一个直接拒绝的交互实现。当记录在尝试期间被提交并被观察到时，`begin()` 报告 `{ status: 'authorized' }`；当人拒绝或调用方撤销时，报告 `{ status: 'cancelled' }`。`cancel(key)` 从第二次调用撤销正在运行的尝试，服务于那种用第二次调用来响应「取消」按钮、却不持有第一次调用 signal 的请求/响应式传输。
 
-人的"不"是一种结果，不是故障。选择拒绝的交互实现让 prompt 以 `AuthorizationDeclinedError` 拒绝，在提示被拒之后才失败的尝试以 `cancelled` 结算，与 signal 撤销完全一致；其余任何 prompt 拒绝仍是抵达调用方的 flow 故障。notice 依同一原则即发即忘，并由 seam 兜底：渲染不了 notice 的界面丢掉的是那条 notice，而不是整次尝试。
+### 可能出错的地方
 
-`authorization/settled (key, settlement)` 在键释放之后触发，覆盖每一种终态。`settlement` 在 `begin()` 能返回的两种状态之外增加了 `failed`：失败以抛出的错误抵达其调用方，因此事件流是未发起该尝试的旁观者唯一能区分"被拒绝"与"出故障"的地方。监听器故障被就地遏制：每个监听器都会执行，抛错或拒绝只记录日志、不改变已结束尝试的结果，仅 `INVARIANT` 编码的故障在其余监听器执行完后重抛。
+- **没有 flow 的凭据是惰性的**——对没有任何 flow 认领的键调用 `begin()` 会抛出 `NO_FLOW`；被卸载插件遗留的记录可以删除，但无法重新授权。
+- **每个凭据同时只允许一次尝试**——已有尝试在运行时再次 `begin()` 会抛出 `ALREADY_IN_FLIGHT`；entry 上的 `inFlight` 让界面预先禁用按钮。
+- **未提交就返回的 flow 会被拒绝**——抛出 `NOT_COMMITTED`，因此 `authorized` 永远意味着记录真的已存储。
+- **点名 flow 未提供的方法会抛出 `UNKNOWN_METHOD`**——不点名则运行 flow 的第一个方法。
+- **「不」是一种结果，不是故障**——被拒绝的 prompt 让尝试以 `cancelled` 结算，与撤销的 signal 完全一致；其余任何失败都以抛出的错误抵达调用方。
 
-## 交互词汇
+-----
 
-notice 是单向的，且从不携带机密：一条消息，以及可选的"人需要打开的页面"和"需要在该页面输入的码"。prompt 是 flow 无法自答的问题——`text`、`secret` 或 `select`——其中 `secret` 与 `text` 的差别仅在呈现方式。prompt 自带 `signal`，使得一个让手输码与浏览器回调赛跑的 flow 可以在尝试继续的同时撤下落败的那个问题；撤销整次尝试则用请求的 signal。

+### 设计理念
+

+- **写入由 flow 拥有。** `run()` 返回即表示记录已通过 `ctx.credentials` 提交；seam 核实的是它在尝试期间观察到的提交——只看记录存在与否，会让重新授权把陈旧记录冒充成新鲜的——并拒绝未提交就返回的 flow。让提交发生在 flow 内部，才能使一个通过自有 store 适配器持久化的库保持为唯一写入方，而不是把凭据复制出来再写第二遍。

+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件：`authorization/settled` 点名的键必已释放 |
+
+### 生命周期
+
+每个键同时只允许一次尝试。`begin()` 校验键与方法、拒绝繁忙键的第二次尝试，并用一个 `AuthorizationSession` 运行 flow——它携带所选方法、取消 signal 以及路由到请求交互的 `notify`/`prompt` 回调。被撤销的尝试会立即结算，即使 flow 从未响应它的 signal——被遗弃的运行任其自行结束，而它若仍设法提交了一条记录，那也是一条人确实授权过的记录。键在 `authorization/settled` 触发之前释放，因此以启动下一次尝试来响应的监听器不会被拒绝；监听器失败按凭据 seam 的规则就地遏制。
+
+### 交互词汇
+
+notice 是单向的，且从不携带机密：一条消息，以及可选的「人需要打开的页面」与「需要在该页面输入的码」。prompt 是 flow 无法自行回答的问题——`text`、`secret` 或 `select`——其中 `secret` 与 `text` 的差别仅在呈现方式。prompt 自带 signal，使得让手输码与浏览器回调赛跑的 flow 可以在尝试继续的同时撤下落败的那个问题；撤销整次尝试则用请求的 signal。这套词汇刻意小于任何单个 provider 的词汇：它描述的是界面必须渲染什么，因此能渲染一个 flow 的界面就能渲染全部 flow。
+
+### 提交确认
+
+尝试期间，seam 监听该 flow 键上的 `credentials/record-updated`，`run()` 返回后再重读 `describeRecord`——确认提交确实发生在当下，因为在重新授权时记录早已存在，只看存在与否会让陈旧凭据冒充新鲜授权。未提交就返回的 flow，或删除记录而非提交的 flow，会抛出 `NOT_COMMITTED`。

+- **没有 flow 的键是惰性的**——seam 只报告已注册的内容，因此被卸载插件遗留的记录可以删除但无法重新授权；识别这种孤儿记录由调用方负责，与 `listRecords()` 的情况相同。

-File-backed [credentials](../credentials/README.md) provider: four layers, one honest precedence.
+## Summary
 
-| Layer | Source id | Writable | Wins |
-|---|---|---|---|
-| Inherited process environment | `env` | no | always |
-| `$DSH_HOME/.credentials.yaml` document | `file` | yes (`set`/`unset`) | over both `.env` layers |
-| `<invocation cwd>/.env` | `project-env` | not here | over the user `.env` |
-| `$DSH_HOME/.env` | `user-env` | not here | otherwise |
+`dsh-credentials-local` is the product's default on-machine credential store: a private file under your harness home where API keys and other secrets live, written from a configuration UI and reloaded automatically when you edit the file yourself. The file is a versioned document with a `refs` section for key values and a `records` section for durable per-plugin credentials, so an authorization grant or provider environment survives restarts beside the keys. Keys come from four places in one fixed order: the environment you launch in wins, then the stored file, then your project's and your home `.env` files. A key you save takes effect immediately, even when an older key sits in a `.env`. Only your OS user can read the file, and the product never hands the agent the file's path.
 
-The launching environment wins because a per-run override (`DEEPSEEK_API_KEY=… dsh`, a CI secret, a container `-e`) is operator intent for this run — and because it cannot be edited from inside, it must be *visibly* read-only: `describe()` reports `source: 'env', writable: false`, and `set`/`unset` reject instead of writing a change the reader would never see.
+## Table of Contents
 
-Everything below it loses to the managed store, so a key written by the Models page takes effect immediately even when an older key sits in a `.env`. Those two layers still resolve when nothing is stored, and `describe()` names them `project-env` or `user-env` with `writable: true` — storing a key replaces them as the effective source.

+- [Further Exploration](#further-exploration)

-Under the product CLI, resolution reads the launcher's frozen [environment snapshot](../../util/launch-environment/README.md) rather than `process.env`: only the snapshot can say whether a value came from the launching shell or from a file. A composition the product CLI did not boot has the inherited environment as its only layer, which keeps embedders on the semantics they already had.
+-----
 
-## Config
+<a id="use-this-package"></a>
+## Use this package
+
+This package gives a composition a local credential store: save API keys and other secrets once, and every request that names them uses them. The common path is explicit: load the store, save keys through the configuration UI or `ctx.credentials`, and let the product resolve them when needed.
+
+### When to use it
+
+Use it as the default local store: the product's base composition loads it, and a key you save through a configuration UI takes effect immediately. Choose a different store when a deployment must keep provider keys away from its own agent — file permissions cannot do that, because the agent's tool processes run as your OS user (see "Who can read the file").
+
+### Setting it up
+
+```yaml
+- name: '@deepseek-ai/dsh-credentials-local'
+  config:
+    path: /absolute/path/to/.credentials.yaml
+```
 
 | Field | Default | Meaning |
 |---|---|---|
-| `path` | `<harness home>/.credentials.yaml` | Credentials document location. |
-| `dshHome` | `$DSH_HOME` or `~/.dsh` | Harness home used when `path` is omitted. |
-| `watch` | `true` | Hot-publish external edits. |
-| `debounceMs` | `100` | Watcher write-settle window. |
+| `path` | `<harness home>/.credentials.yaml` | Where the credential file lives |
+| `dshHome` | `$DSH_HOME` or `~/.dsh` | Harness home used when `path` is omitted |
+| `watch` | `true` | Reload the file automatically when it changes on disk |
+| `debounceMs` | `100` | Wait this long after a change before reloading, in milliseconds |
 
-## The document
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-credentials-local) is the exhaustive source for every accepted field and its JSDoc.
+
+### Storing and removing keys
+
+Save a key with `set`, remove it with `unset`, and check whether a key is configured with `describe` — the same operations the credential API provides:
+
+```ts
+import type { Context } from '@deepseek-ai/cordis'
+import { credentialRef } from '@deepseek-ai/dsh-credentials'
+
+declare const ctx: Context
+
+const ref = credentialRef('DEEPSEEK_API_KEY')
+await ctx.credentials.set(ref, 'sk-…')          // save
+await ctx.credentials.describe(ref)             // { configured, source?, writable } — never the value
+await ctx.credentials.unset(ref)                // remove
+```
+
+A key you save is usable by the next request that names it, and `describe` reports whether it is set, where it comes from, and whether you can write to it — never the value itself. Records persist in the same file, addressed by `<owner>/<id>` and managed with the seam's record operations (`readRecord`, `describeRecord`, `listRecords`, `modifyRecord`, `deleteRecord`).
+
+### Where keys come from
+
+Keys are resolved in one fixed order — the first place that has a value wins:
+
+| Place | Writable? | Wins over |
+|---|---|---|
+| The environment you launched in (`DEEPSEEK_API_KEY=… dsh`) | no | everything |
+| The stored file | yes (`set`/`unset`) | both `.env` files |
+| Your project's `.env` (`<invocation cwd>/.env`) | not here | your home `.env` |
+| Your home `.env` (`$DSH_HOME/.env`) | not here | nothing |
+
+The launching environment wins because a per-run override — `DEEPSEEK_API_KEY=… dsh`, a CI secret, a container `-e` — is this run's explicit intent; it cannot be edited from inside the product, so it is reported read-only and writes to it are refused. Everything else loses to the stored file, which is why a key you save takes effect immediately even when an older key sits in a `.env`; those two `.env` layers resolve when nothing is stored. The environment layer is the launcher's snapshot taken at launch ([environment snapshot](../../util/launch-environment/README.md)), so a variable exported after startup is not seen.
+
+### The credential file
 
 A versioned YAML document with one section per key space, and nothing else:
 
@@ -53,41 +106,109 @@ records:
     kind: api-key               # neither: the owner confirmed the ambient credential chain
 ```
 
-The document holds credentials only, so every deviation is a rejection rather than a skipped entry — a silently ignored key would read as "the credential I stored has no effect". A non-mapping root, an unknown top-level key, a key that is not addressable in its space, a wrong-typed value, an empty string, an unknown record tag or field, a duplicate key, and malformed YAML all fail: loud at boot, and warn-and-keep-the-last-good-snapshot on a live reload.
+You can edit the file directly — the store reloads it automatically and picks up the change, including a key or record you delete. `refs` holds key values by environment-variable name; `records` holds per-plugin credentials by `<owner>/<id>`, each tagged `api-key` or `grant`, whose grant payload the store keeps verbatim because only its owner can interpret it. Comments and the formatting of untouched entries survive product writes; a comment directly above an entry is that entry's note and is removed with it. The file holds only credentials, so anything else is refused loudly rather than silently ignored: a non-mapping root, an unknown top-level key, a key that is not addressable in its space, a wrong-typed or empty value, an unknown record tag or field, duplicate keys, and malformed YAML all fail at startup, and on a live reload the last good content keeps serving with a warning.
 
-A `grant` payload must survive a JSON round trip, enforced in both directions. YAML spells values JSON has none for — `.inf`, alias cycles — and an owner may hand over a `Date` or a `bigint`; either way the store refuses rather than saving something it could not read back exactly as written.
+A key's value can be any text, multi-line values included — no quoting tricks needed. An empty value means "no key", which is why an empty string in the file is rejected: removing a key deletes it, it does not blank it. A `grant` payload must survive a JSON round trip, enforced on the way in and on the way out, so the store refuses a value it could not read back exactly as written. If the file on disk no longer parses, saving fails instead of overwriting content the product could not read.
 
-The pre-release layout was a flat mapping with no `version`. A boot that recognizes it exactly — addressable names over non-empty string scalars, no directives — upgrades the document in place under the writer lock: the original lines nest verbatim under `refs:`, so values, comments, and spellings survive byte for byte. Any other flat shape is refused by name, with the entry count and the one edit needed (`version: 1`, nest under `refs:`) — never read as an empty store, which would surface as an authentication failure on the first request instead of at load. A live reload never migrates: a flat document restored mid-run keeps the last good snapshot until the next boot.
+### Who can read the file
 
-Writes patch the parsed document rather than rebuilding it, so comments and the formatting of every untouched entry survive. A comment directly above an entry is that entry's annotation and is removed with it. Every write first re-reads the document under the cross-process writer lock of [`dsh-atomic-write`](../../util/atomic-write/README.md) and publishes anything it had not observed, then commits atomically with mode `0600` under an owner-only (`0700`) directory — so a concurrent writer or an external edit inside the watcher's debounce window is folded in rather than overwritten. An on-disk document that no longer parses fails the write instead of overwriting content the provider could not understand.
+Only your OS user can read the file: the product creates it with owner-only permissions, and on POSIX it refuses to load a file that any other user can read — the error tells you to run `chmod 600`. Windows has no mode to inspect, so the check is skipped there rather than faked. The agent is not another user: its tool processes run as you, so they can read the file like any other file you own. The product never hands the agent the file's path and never loads the file into the environment, so reaching a value takes a deliberate read of a path the agent was not given. That is discretion, not a boundary: a deployment that must keep provider keys away from its own agent cannot get there with file permissions.
 
-Any string value round-trips, multi-line values included, so no entry is unwritable for want of a quoting style. An empty stored value is absent, per the seam rule — which is why an empty string in the document is rejected outright: `unset` removes a key, it does not blank it.
+### What can go wrong
 
-## Permissions
+- **A key the launching environment supplies is read-only** — `DEEPSEEK_API_KEY=… dsh` wins for this run; saving or removing it is refused. Clear the variable in the launching shell first.
+- **An empty value cannot be saved** — storing an empty string is refused; remove the key instead.
+- **The store refuses to load a file it cannot trust** — a file any other user can read, malformed YAML, or an unreachable path fails at startup; on a live reload the last good content keeps serving with a warning.
+- **Changes made at the same time are both kept** — if you edit the file while the product writes, your change is folded in rather than overwritten.
 
-The provider creates the directory `0700` and creates or atomically replaces the document `0600`. It holds what it *reads* to that same bound: on POSIX a document carrying any group or other permission bit fails before its contents are parsed — at boot and on every reload — and the error names the `chmod 600` repair. Windows has no mode to inspect, so the check is skipped there rather than faked.

-## Hot reload
+<a id="understand-the-implementation"></a>
+## Understand the implementation
 
-External edits publish `credentials/reference-updated` per changed reference after the snapshot is replaced **wholesale** — an entry deleted on disk never lingers in memory. Before Chokidar opens the target, the provider realpaths its deepest existing ancestor and restores any missing suffix; file access and diagnostics retain the configured path, while Windows cannot mix an 8.3 alias with long-form libuv events. The provider's own writes are recognized by content and publish exactly their one commit event. An unreadable or invalid document at runtime keeps the last good snapshot and warns; an absent file is an empty store; an unreadable or invalid file at boot fails loud.

-## Security boundary
+This section explains the design decisions behind the provider and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
 
-The document is `0600` under a `0700` directory, which stops other OS users — **not** the model. Tool processes (bash, the filesystem tools) run as the same user, and the shipped `workspace-write` file policy confines mutations rather than reads, so they can read this file exactly like any other file the user owns; no sandbox mode singles it out. What the harness does hold to is narrower: it never hands the model a resolved path to the document, and never loads it into the process environment — unlike `$DSH_HOME/.env`, which is the user's ordinary environment layer (see [app-boot's Harness-home layers](../../boot/app-boot/README.md#profiles)) — so reaching the value takes a deliberate read of a path the agent was not given.
+### Design philosophy
 
-That is discretion, not a boundary. A deployment that must keep provider keys away from its own agent cannot get there with file permissions; an OS-keychain provider — a store the model's processes cannot read at all — is the deferred answer and belongs beside this provider as a sibling package.
+- **One honest precedence.** The inherited environment wins because it is this run's explicit intent and cannot be edited from inside; everything below it loses to the managed store, so a stored key is never displaced by a stale `.env`.
+- **The document holds only credentials.** A versioned document with `refs` and `records` sections rather than a dotenv file: a store the harness owns and never materializes into the environment cannot also serve as the user's environment layer, which would shadow non-secret entries behind its precedence.
+- **Writes patch, reloads replace.** Line edits preserve comments and untouched entries under the cross-process writer lock; reloads swap the parsed snapshot wholesale so a deleted entry never lingers in memory.
+- **Fail loud where trust is at stake.** Boot and reload reject a document that is unreadable, invalid, or readable beyond its owner; a live reload that fails keeps the last good snapshot and warns rather than taking the process down.
 
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Provider: layer resolution, strict document parse, reference and record write paths under the writer lock, watcher lifecycle, permissions check |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; the seam companion owns the event lifecycle contract) |
+
+### Resolution and write paths
+
+`resolve` and `describe` read the inherited environment snapshot, the parsed document snapshot, and the `.env` fallbacks in precedence order. `set`/`unset` queue onto one exclusive operation chain: entry checks reject early (disposed, empty value, environment-shadowed), and the queue re-judges them at run time before a read-modify-write under the writer lock commits and fires `credentials/reference-updated` exactly once.
+
+`modifyRecord` runs on the same chain and lock: it re-reads the document, shows the mutation the record as it stands, admits the result — a non-empty api key, a grant payload that survives a JSON round trip — renders the record wholesale, and commits, firing `credentials/record-updated` once. A composition the product CLI did not boot has only the inherited environment as its layer.
+
+### Reload lifecycle
+
+A watcher event or the ready reconcile queues a refresh behind the same chain. `reconcileFromDisk` re-checks permissions, re-reads the text, replaces both snapshots wholesale when the text differs, and publishes one event per changed reference or record; content equal to the text cache — including the provider's own writes — is a no-op. Disposal sets the closed flag, stops accepting events, closes the watcher, and waits out queued operations so nothing publishes after teardown.
+
+### Document versioning
+
+The document carries `version: 1`, stamped on every write. A boot that recognizes the pre-release flat layout — a bare mapping of reference names with no `version` — upgrades the document in place under the writer lock, nesting the original lines under `refs:` so values, comments, and spellings survive byte for byte; any other unversioned shape is refused by name rather than read as an empty store. A live reload never migrates: a flat document restored mid-run keeps the last good snapshot until the next boot.
+
+### Diagnostics never quote a value
+
+The YAML parser's own message quotes the offending source line, which in this document is the secret itself. Every diagnostic therefore carries only the error code and position — a key name is safe to print, a value is not.

 ## Model Experience
 
-Indirectly, through the consuming LLM adapters: stored values authorize their provider requests, and the adapter owns every model-visible surface.
+Indirectly, through the consumers of `ctx.credentials`, which own any model-facing behavior a stored value enables.
 
 #### KV Cache effect
 
-No direct invalidation; credentials never enter a request prefix.

 ## Known Limitations and Deferred Work
 
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define when the provider is a poor fit or needs special operational care. They are current package constraints, not a task backlog.
+
 - **Same-reference concurrent writes are last-write-wins** — the writer lock and the read-modify-write keep concurrent writers from dropping each other's entries, but two writers editing one reference still resolve to the later write; there is no revision check.
-- **A same-UID process can read the document** — see [Security boundary](#security-boundary): the file-effect sandbox modes do not deny reads, and an OS-keychain provider is deferred.
+- **A same-UID process can read the document** — the file-effect sandbox modes do not deny reads, and an OS-keychain provider is deferred.
 - **Environment changes are invisible** — the snapshot is frozen at launch, so a variable exported after startup reaches neither resolution nor `describe`; changing an environment-sourced credential takes a restart.
 - **Atomic, not crash-durable** — inherited from `dsh-atomic-write`; the store re-reads on boot.

-文件型[凭据](../credentials/README.zh.md)提供方：四层来源，一套明确的优先级。
+## 概述
 
-| 层 | 来源 id | 可写 | 优先 |
-|---|---|---|---|
-| 继承的进程环境 | `env` | 否 | 始终优先 |
-| `$DSH_HOME/.credentials.yaml` 文档 | `file` | 是（`set`/`unset`） | 高于两个 `.env` 层 |
-| `<invocation cwd>/.env` | `project-env` | 不在此处 | 高于用户 `.env` |
-| `$DSH_HOME/.env` | `user-env` | 不在此处 | 其余情况 |
+`dsh-credentials-local` 是产品默认的本机凭据存储：harness home 下的一个私有文件，存放 API 密钥与其他机密，可由配置界面写入，你自己编辑该文件时也会自动重载。该文件是带版本的文档，含一个存放密钥值的 `refs` 分节和一个存放持久化按插件记录的 `records` 分节，因此授权 grant 或提供方环境值能与密钥一起跨重启保留。密钥来自四个位置，顺序固定：你启动时的环境优先，其次是存储文件，再次是项目和主目录的 `.env` 文件。你保存的密钥会立即生效，即使某个 `.env` 里还留着更旧的密钥。只有你的 OS 用户能读取该文件，而且产品绝不把文件路径交给 agent（智能体）。
 
-启动环境优先，因为按次覆盖（`DEEPSEEK_API_KEY=… dsh`、CI 机密、容器 `-e`）代表本次运行的操作者意图——而它无法从进程内部修改，就必须*可见地*只读：`describe()` 报告 `source: 'env', writable: false`，`set`/`unset` 直接拒绝，而不是写下一个读取方永远看不到的变更。
+## 目录
 
-它之下的所有来源优先级都低于受管存储，因此 Models 页写入的密钥会立即生效，即使某个 `.env` 里还留着更旧的密钥。没有存储任何东西时这两层仍会参与解析，`describe()` 会把来源报告为 `project-env` 或 `user-env` 且 `writable: true`——存入一个密钥就会取代它们成为生效来源。

+- [进一步探索](#further-exploration)
+- [模型体验](#model-experience)
+- [已知限制与延期工作](#known-limitations-and-deferred-work)
+- [开发备注](#dev-note)
 
-在产品 CLI（命令行界面）下，解析读取的是启动器冻结的[环境快照](../../util/launch-environment/README.zh.md)而不是 `process.env`：只有快照才说得清某个值来自启动 shell 还是来自某个文件。并非由产品 CLI 启动的组合只有继承环境这一层，这让嵌入方保持它们原有的语义。
+-----
 
-## 配置
+<a id="use-this-package"></a>
+## 使用本包
+
+本包为组合提供本地凭据存储：API 密钥与其他机密只需保存一次，之后每个按名引用它们的请求都会用到。常用路径是显式的：加载存储、通过配置界面或 `ctx.credentials` 保存密钥，然后在需要时由产品解析。
+
+### 何时使用
+
+把它作为默认本地存储：产品的 base 组合会加载它，你通过配置界面保存的密钥会立即生效。当部署必须让提供方密钥远离自身 agent 时选择其他存储——文件权限做不到这一点，因为 agent 的工具进程以你的 OS 用户身份运行（见「谁能读取该文件」）。
+
+### 设置
+
+```yaml
+- name: '@deepseek-ai/dsh-credentials-local'
+  config:
+    path: /absolute/path/to/.credentials.yaml
+```
 
 | 字段 | 默认值 | 含义 |
 |---|---|---|
-| `path` | `<harness home>/.credentials.yaml` | 凭据文档位置。 |
-| `dshHome` | `$DSH_HOME` 或 `~/.dsh` | `path` 缺省时使用的 harness home。 |
-| `watch` | `true` | 热发布外部编辑。 |
-| `debounceMs` | `100` | watcher 写入稳定窗口。 |
+| `path` | `<harness home>/.credentials.yaml` | 凭据文件所在位置 |
+| `dshHome` | `$DSH_HOME` 或 `~/.dsh` | `path` 缺省时使用的 harness home |
+| `watch` | `true` | 文件在磁盘上变化时自动重载 |
+| `debounceMs` | `100` | 变化后等待这么久再重载，单位为毫秒 |
 
-## 文档本身
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-credentials-local)是每个受支持字段及其 JSDoc 的穷尽式真源。
 
-一个带版本的 YAML 文档，每个键空间一个分节，除此之外别无他物：
+### 存储与移除密钥
+
+用 `set` 保存密钥、用 `unset` 移除、用 `describe` 检查密钥是否已配置——与凭据 API 提供的操作相同：
+
+```ts
+import type { Context } from '@deepseek-ai/cordis'
+import { credentialRef } from '@deepseek-ai/dsh-credentials'
+
+declare const ctx: Context
+
+const ref = credentialRef('DEEPSEEK_API_KEY')
+await ctx.credentials.set(ref, 'sk-…')          // save
+await ctx.credentials.describe(ref)             // { configured, source?, writable } — never the value
+await ctx.credentials.unset(ref)                // remove
+```
+
+你保存的密钥会被下一个按名引用它的请求使用；`describe` 报告它是否已设置、来自哪里、能否写入——绝不返回值本身。记录也持久化在同一文件中：插件按 `<owner>/<id>` 寻址一条记录，并用 seam 的记录操作（`readRecord`、`describeRecord`、`listRecords`、`modifyRecord`、`deleteRecord`）管理它。
+
+### 密钥从哪里来
+

-该文档只存放凭据，因此任何偏离都是拒绝，而不是跳过某个条目——被静默忽略的键读起来就是「我存进去的凭据没有生效」。非 mapping 的根、未知的顶层键、在其空间中不可寻址的键、类型不符的值、空字符串、未知的记录标签或字段、重复键以及格式错误的 YAML 全部失败：启动时明确报错，运行期热重载则告警并保留最后可用快照。

-`grant` 的 payload 必须能经受 JSON 往返，读写两个方向都强制。YAML 能拼写出 JSON 没有的值——`.inf`、别名环——拥有者也可能递来 `Date` 或 `bigint`；无论哪种，存储都选择拒绝，而不是存下一个自己无法逐字读回的东西。

-发布前的旧布局是没有 `version` 的扁平 mapping。启动时若能精确识别它——可寻址名称对非空字符串标量、且没有文档指令——就在写锁下原地升级：原有各行逐字下沉到 `refs:` 之下，值、注释与拼写逐字节保留。其余任何扁平形态都会被指名拒绝，并给出条目数与唯一需要做的编辑（`version: 1`，条目下沉到 `refs:`）——绝不当作空存储读过去，否则它会以第一次请求认证失败的形式出现，而不是在加载时。热重载从不迁移：运行中被恢复出来的扁平文档只会保住上一份完好快照，直到下次启动。
+### 谁能读取该文件
 
-写入是对已解析文档打补丁而不是重建，因此注释与所有未触及条目的排版都会保留。直接位于某条目上方的注释属于该条目的注解，会随它一起删除。每次写入都先在 [`dsh-atomic-write`](../../util/atomic-write/README.zh.md) 的跨进程写锁下重读文档、把此前未观察到的一切发布出去，再在仅属主可访问（`0700`）的目录下以 `0600` 权限原子提交——因此并发写入者、或落在 watcher 防抖窗口内的外部编辑会被并入，而不是被覆盖。磁盘上已经无法解析的文档会让写入失败，而不是覆盖提供方读不懂的内容。
+只有你的 OS 用户能读取该文件：产品以仅属主可访问的权限创建它，在 POSIX 上还会拒绝加载任何其他用户可读的文件——错误会提示你运行 `chmod 600`。Windows 没有可检查的 mode，因此在那里跳过该检查而不是伪造它。agent 不是另一个用户：它的工具进程以你的身份运行，因此它们读这个文件与读你拥有的任何其他文件毫无二致。产品绝不把文件路径交给 agent，也绝不把文件载入环境，因此要拿到某个值，需要刻意去读一条并未交给 agent 的路径。这是审慎，不是边界：必须让提供方密钥远离自身 agent 的部署无法靠文件权限做到。
 
-任何字符串值都能往返，包括多行值，因此不会再有条目因为缺少可用引号样式而不可写。空的存储值等于不存在（seam 规则）——这也正是文档中的空字符串被直接拒绝的原因：`unset` 删除键，而不是把它置空。

+本节解释提供方背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
 
-## 安全边界
+### 设计理念
 
-文档在 `0700` 目录下以 `0600` 权限存放，这挡得住其他 OS 用户，**挡不住**模型。工具进程（bash、文件系统工具）以同一用户身份运行，而已交付的 `workspace-write` 文件策略限制的是修改而非读取，因此它们读这个文件与读该用户拥有的任何其他文件毫无二致；也没有任何沙箱模式会把它单独挑出来。harness 真正守住的更窄：它绝不把该文档的解析后路径交给模型，也绝不把它载入进程环境——这与用户的普通环境层 `$DSH_HOME/.env` 不同（见 [app-boot 的 Harness home 各层](../../boot/app-boot/README.zh.md#profiles)）——因此要拿到这个值，需要刻意去读一条并未交给 agent（智能体）的路径。
+- **一套明确的优先级。** 继承环境优先，因为它是本次运行的明确意图且无法从进程内部修改；它之下的所有来源都输给受管存储，因此已存密钥永远不会被陈旧的 `.env` 挤掉。
+- **文档只存放凭据。** 它是带 `refs` 与 `records` 分节的版本化文档，而不是 dotenv 文件：一个 harness 拥有、且绝不物化进环境的存储，不能同时充当用户的环境层，否则会以自己的优先级遮蔽非机密条目。
+- **写入打补丁，重载整体替换。** 行编辑在跨进程写锁下保留注释与未触及条目；重载整体交换解析后的快照，已删除条目绝不在内存滞留。
+- **信任攸关处明确报错。** 启动与重载都会拒绝不可读、无效或可被属主之外读取的文档；失败的活动重载保留最后可用快照并告警，而不是拖垮进程。
 
-这是审慎，不是边界。必须让提供方密钥远离自身 agent 的部署无法靠文件权限做到；OS 钥匙串提供方——一种模型运行所在进程根本无法读取的存储——才是延后的答案，它应当作为平级包与本提供方并列。

+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 提供方：层解析、严格文档解析、写锁下的引用与记录写路径、watcher 生命周期、权限检查 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；事件生命周期约定归 seam 伴生插件） |
+
+### 解析与写入路径
+
+`resolve` 与 `describe` 按优先级顺序读取继承环境快照、已解析文档快照与 `.env` 后备层。`set`/`unset` 排入同一条独占操作链：入口检查提前拒绝（已释放、空值、被环境遮蔽），队列在运行时会重新判定，随后在写锁下执行读-改-写、提交，并恰好触发一次 `credentials/reference-updated`。
+
+`modifyRecord` 走同一条链与同一把锁：它重新读取文档、把当前记录交给变更函数、准入其结果——非空的 api key、能经受 JSON 往返的 grant payload——整体渲染该记录并提交，恰好触发一次 `credentials/record-updated`。并非由产品 CLI 启动的组合只有继承环境这一层。
+
+### 重载生命周期
+
+watcher 事件或 ready 对账把一次刷新排到同一链条之后。`reconcileFromDisk` 重新检查权限、重读文本，文本有差异时整体替换两个快照，并按变更引用或记录逐个发布事件；与文本缓存一致的内容——包括提供方自己的写入——是 no-op。释放时设置 closed 标志、停止接收事件、关闭 watcher，并等待排队操作结算完毕，确保 teardown 之后不再有任何发布。
+
+### 文档版本化
+
+文档携带 `version: 1`，每次写入都会盖上版本戳。启动时若识别出预发布扁平布局——没有 `version` 的裸引用名 mapping——会在写锁下就地升级，把原始行嵌套到 `refs:` 之下，值、注释与拼写逐字节保留；任何其他无版本形态都会按名拒绝，而不会被当作空存储。运行期热重载绝不迁移：中途恢复的扁平文档会保留最后可用快照，直到下一次启动。
+
+### 诊断信息绝不引用值
+
+YAML 解析器自己的消息会引用出错的那行源码，而在这份文档里那行就是机密本身。因此每条诊断只携带错误码与位置——键名可以安全打印，值不行。

-Credential Service Definition (`ctx.credentials`). One doctrine, three consequences:
+## Summary
 
-**Configuration carries references to secrets, never the secrets.** A settings section or `cordis.yml` entry says `apiKeyEnv: DEEPSEEK_API_KEY`; the value behind that reference lives with a credential provider. So the settings document stays safe to sync and to render in a configuration UI, `describe()` can answer "is this configured, where from, can I write it" without ever holding a value, and rotating a secret touches no configuration file.
+`dsh-credentials` keeps secret values out of configuration: you store an API key once and reference it by name (`DEEPSEEK_API_KEY`) from settings or `cordis.yml`, and the product supplies the value when a provider request needs it. Beside those references it also keeps durable credential records — per-plugin entries such as an authorization grant or provider environment values — so a plugin holds what it manages for its own ids across restarts. A rotated key takes effect on the very next request — no restart, no configuration edit. Configuration UIs can tell you whether a key or record is set, where it comes from, and whether you can change it, without ever showing a value. Storing an empty value counts as "no key", so a blank can never masquerade as a configured secret; a record's presence is the whole fact, so an entry carrying no value is a deliberate statement, not a blank.
 
-**Consumers resolve per operation.** `resolve(ref)` is called at the start of each operation (the LLM adapters resolve once per model request) and never cached across operations — that read is what makes a changed credential reach the very next request without restarting any plugin.
+## Table of Contents
 
-**An empty stored value is absent.** Everywhere: `resolve` skips it, `describe` reports it unconfigured. A blank can never masquerade as a configured secret.

-## Two key spaces, two questions
+-----
 
-A `CredentialRef` answers *what is behind this environment-variable name*, layered over the process environment, the managed store, and `.env` files. Everything above describes that half.
+<a id="use-this-package"></a>
+## Use this package
 
-A `CredentialKey` answers *what credential does this plugin hold for this id*. Nothing can layer here — an authorization grant has no environment to be read from — so presence of the record is the whole fact, and the empty-value rule does not apply: an `api-key` record carrying neither a key nor environment values states that its owner confirmed ambient authentication, which is configured.
+This package is the part of the product that stores and looks up secret values: store a key once, reference it by name everywhere, and read, check, or remove it at any time. It also keeps durable credential records, so a plugin can store, update, and remove the credentials it holds for its own ids. The product's default composition already includes a credential store; a custom composition loads the local store package with a file path.
 
-The key is `<scope>/<id>`, where `scope` is the **owning plugin's registered name**. The scope is the owner rather than the domain because a `grant` payload is written in its owner's format: two plugins serving the same provider name would otherwise read each other's payload, and a record left behind by an uninstalled plugin could not be told apart from a live one. The `/` also keeps the two grammars disjoint, so the key spaces can never collide. A consumer whose id arrives from somewhere else — a settings dict key, a library's own provider id — asks `isCredentialKeySegment` before building a key, because an id outside the grammar can never have stored a record and should read as "nothing stored" rather than throw on the address.
+### When to use it
 
-## Surface
+Use a credential store whenever configuration must stay free of secret values: settings files that are synced, shared, or rendered in a configuration UI, or teams that rotate keys without editing configuration. Use records when a plugin must keep credentials with no single environment variable — an authorization grant from a sign-in flow, or provider environment values — and when a configuration UI should list what a user is authorized for. A configuration UI can show whether a key or record is set, where it comes from, and whether you can change it — never the value itself. If you only need one fixed environment variable, read that variable directly and skip the store.
+
+### Adding it to your composition
+
+Load the local store package with a document path:
+
+```yaml
+- name: '@deepseek-ai/dsh-credentials-local'
+  config:
+    path: /absolute/path/to/.credentials.yaml
+```
+
+The local store README owns the full configuration surface; the generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-credentials-local) is the exhaustive field list.
+
+### Storing, checking, and removing keys
 
 ```ts
 import type { Context } from '@deepseek-ai/cordis'
-import { credentialKey, credentialRef } from '@deepseek-ai/dsh-credentials'
+import { credentialRef } from '@deepseek-ai/dsh-credentials'
 
 declare const ctx: Context
 
-const ref = credentialRef('DEEPSEEK_API_KEY')            // POSIX shell identifier, branded
-const hit = await ctx.credentials.resolve(ref)           // { value, source } | undefined
-const info = await ctx.credentials.describe(ref)         // { configured, source?, writable } — never the value
-await ctx.credentials.set(ref, 'sk-…')                   // rejects while a read-only source shadows the ref
-await ctx.credentials.unset(ref)                         // no-op when absent; same shadowing rule
+const ref = credentialRef('DEEPSEEK_API_KEY')          // POSIX shell identifier, branded
+const hit = await ctx.credentials.resolve(ref)         // { value, source } | undefined
+const info = await ctx.credentials.describe(ref)       // { configured, source?, writable } — never the value
+await ctx.credentials.set(ref, 'sk-…')                 // rejects while a read-only source shadows the ref
+await ctx.credentials.unset(ref)                       // no-op when absent; same shadowing rule
+```
+
+Store a key with `set`, remove it with `unset`, check its status with `describe`, and read the current value with `resolve` when an operation needs it. `describe` reports whether the key is set, where it comes from, and whether you can write to it — it never returns the value.
+
+### Storing, updating, and removing records
+
+A plugin addresses each record by `<scope>/<id>` — its own registered name plus an id it chooses, such as a provider route key — and reads, modifies, or removes what it holds:
+
+```ts
+import type { Context } from '@deepseek-ai/cordis'
+import { credentialKey } from '@deepseek-ai/dsh-credentials'
+
+declare const ctx: Context
 
 const key = credentialKey('llm-pi-ai', 'openai-codex')   // <owner>/<id>, branded
-await ctx.credentials.readRecord(key)                    // CredentialRecord | undefined
+const hit = await ctx.credentials.readRecord(key)        // CredentialRecord | undefined
 await ctx.credentials.describeRecord(key)                // { configured, kind?, writable } — never the value
 await ctx.credentials.listRecords()                      // [{ key, kind }] — never values
 await ctx.credentials.modifyRecord(key, async () => ({ kind: 'grant', payload: { token: '…' } }))
 await ctx.credentials.deleteRecord(key)                  // no-op when absent
 ```
 
-`modifyRecord` is the only write path because a correct write depends on the current value: a token refresh is read-decide-replace, and the mutation must see the record as it stands at the moment the write is exclusive. Exclusion holds across processes, which is what stops two of them rotating one refresh token and losing whichever wrote first. Returning `undefined` from the mutation leaves the entry untouched and announces nothing.
+`modifyRecord` is the only write path: it hands your mutation the record as it stands at the moment the write is exclusive, and returning `undefined` leaves the entry untouched. Records have no empty-value rule — a record carrying neither a key nor environment values states that its owner confirmed ambient authentication — and a configuration UI can enumerate every record to show what you are authorized for and find records a removed plugin left behind.
 
-`listRecords` exists even though the reference half has no enumeration by design. References are discovered from settings schemas (`apiKeyEnv` fields); records have no such path, so a surface that cannot list them cannot show what a user is authorized for, nor find an orphan left by an uninstalled plugin.
+### Using a key in configuration
 
-A `grant` record's `payload` is opaque: the seam never reads, validates, or reshapes it. The one constraint is that it survives a JSON round trip, which the provider enforces on the way in and on the way out — a value the store could not read back exactly as written is refused rather than stored lossily.
+A settings section or `cordis.yml` entry names a key instead of containing it — an LLM adapter, for example, takes `apiKeyEnv`:
 
-`credentials/reference-updated (ref)` fires after a committed change to a provider-managed source — a `set`, an `unset`, or an external edit observed in storage. Ambient process-environment changes are not observable and never emit. Consumers do not need the event (they re-resolve per operation); it exists for configuration UIs refreshing a "configured" badge. Its declaration lives in the client-safe `./types` subpath export together with the `CredentialRef` type it names (the package root re-exports the type), so a consumer outside the Host compilation face reads the very signature the Host emits instead of restating it.
+```yaml
+apiKeyEnv: DEEPSEEK_API_KEY
+```
 
-The shadowing rule on `set`/`unset` is deliberate fail-loud: when a read-only source (the live process environment, in the local provider) currently supplies the reference, a write would appear to succeed while resolution keeps returning the shadowing value — the seam rejects instead, and `describe().writable` lets a UI render the reference read-only up front.
+Requests that need the key use its current stored value, so rotating the key takes effect on the very next request — no restart and no configuration edit.
 
-## Providers
+### What can go wrong
 
-[`dsh-credentials-local`](../credentials-local/README.md) layers the inherited process environment over its managed `$DSH_HOME/.credentials.yaml` document, with the launcher's project and user `.env` layers as fallbacks. The seam shape leaves room for keyring-, helper-command-, and KMS-backed providers; a remote settings provider never needs to carry secrets.
+- **A key the launching environment supplies cannot be overwritten** — `DEEPSEEK_API_KEY=… dsh` (or a CI secret, a container `-e`) wins for this run and is reported read-only; clear the variable in the launching shell before storing a different value.
+- **An empty value cannot be stored** — storing an empty string is refused; remove the key instead.
+- **Key values never appear in configuration UIs or diagnostics** — the UI shows whether a key is set, where it comes from, and whether you can change it; the value itself stays in the store.

+
+This section explains the design decisions behind the package and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+One doctrine and four consequences:
+
+- **Configuration carries references, never secrets.** A settings section or `cordis.yml` entry names a credential; the value behind the reference lives with a provider. The settings document stays safe to sync and to render, `describe()` answers without holding a value, and rotating a secret touches no configuration file.
+- **Consumers resolve per operation.** Resolution is a per-call read with no cross-operation cache; that read is the hot-update mechanism.
+- **An empty stored value is absent.** `resolve` skips it, `describe` reports it unconfigured — a blank can never masquerade as a configured secret.
+- **Records are durable, and presence is the fact.** A record is stored per `<scope>/<id>` and survives restarts; the empty-value rule does not apply, so an `api-key` record carrying neither a key nor environment values is a deliberate statement, not a blank.
+- **Listener failures are contained.** `notifyUpdated` fans `credentials/reference-updated` out so every listener runs; a sync throw or async rejection is logged without changing the committed operation's outcome, except `INVARIANT`-coded failures, which rethrow after every listener ran.
+
+### The credentials/reference-updated event
+
+`credentials/reference-updated (ref)` fires after a committed change to a provider-managed source — a `set`, an `unset`, or an external edit observed in storage. Ambient process-environment changes are not observable and never emit. Consumers do not need the event (they re-resolve per operation); it exists for configuration UIs refreshing a "configured" badge.
+
+`credentials/record-updated (key)` fires after a committed change to a stored record — a `modifyRecord` that wrote, a `deleteRecord` that removed, or an external edit observed in storage. It stays a separate event because the two key grammars are disjoint: a listener receiving both spaces on one event could not tell which one a subject belongs to.
+
+### Record write and read paths

+`modifyRecord` is the only record write path because a correct write depends on the current value: a token refresh is read-decide-replace, and the mutation sees the record as it stands at the moment the write is exclusive — returning `undefined` leaves the entry untouched. Exclusion holds across processes where the backing store supports it, which is what stops two processes rotating one refresh token from losing whichever wrote first. Reads mirror the reference half but never layer: nothing can shadow a record, and a `grant` payload is returned exactly as its owner wrote it, because only the owning plugin can interpret it.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Service Definition: the `credentialRef`/`credentialKey` brands, `ResolvedCredential`/`CredentialInfo`/`CredentialRecordInfo`, the abstract provider over both key spaces, contained fan-out |
+| [`src/types.ts`](src/types.ts) | Client-safe type surface: the `CredentialRef` and `CredentialKey` brands, the stored-record union, the `credentials/reference-updated` and `credentials/record-updated` declarations |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion: `credentials/reference-updated` only fires while a credentials service is live |
+
+### Client-safe types
+
+The `./types` subpath export holds the event declarations together with the `CredentialRef` and `CredentialKey` brands and the stored-record union they name, and the package root re-exports them. A consumer outside the Host compilation face therefore reads the very signature the Host emits instead of restating it.
+
+### Lifecycle
+
+The service is a Cordis `Service` registered by the provider: disposing the mounting fiber removes `ctx.credentials`. The invariant companion checks that `credentials/reference-updated` never fires without a live service — an emission after disposal means a provider leaked work past its teardown quiescence.

 [English](README.md) | 中文
 
-凭据 Service Definition（`ctx.credentials`）。一条准则，三个推论：
+## 概述
 
-**配置只携带对机密的引用，绝不携带机密本身。** settings 分节或 `cordis.yml` 条目写 `apiKeyEnv: DEEPSEEK_API_KEY`，引用背后的值存放在凭据提供方处。于是设置文档可以放心同步、放心渲染进配置界面；`describe()` 无需持有值就能回答「配置了吗、来自哪层、能否写入」；轮换机密不触碰任何配置文件。
+`dsh-credentials` 让机密值留在配置之外：API 密钥只存一次，在 settings 或 `cordis.yml` 中按名引用（`DEEPSEEK_API_KEY`），产品在提供方请求需要时提供该值。在这些引用之外，它还保存持久化的凭据记录——按插件组织的条目，例如授权 grant 或提供方环境值——让插件跨重启持有它为自身 id 管理的凭据。轮换后的密钥会作用于紧随其后的下一次请求——无需重启，无需改配置。配置界面能告诉你某个密钥或记录是否已设置、来自哪里、能否修改，而绝不显示值本身。存储空值等于「没有密钥」，因此空白永远不会伪装成已配置的机密；记录的存在本身就是全部事实，一条不含任何值的条目是有意陈述，而不是空白。
 
-**消费方按操作解析。** `resolve(ref)` 在每个操作开始时调用（LLM（大语言模型）适配器每次模型请求解析一次），绝不跨操作缓存——正是这次读取让改过的凭据无需重启任何插件就作用于下一次请求。
+## 目录
 
-**空的存储值等于不存在。** 处处如此：`resolve` 跳过它，`describe` 报告未配置。空白永远不会伪装成已配置的机密。

-## 两个键空间，两个问题
+<a id="use-this-package"></a>
+## 使用本包
 
-`CredentialRef` 回答的是*这个环境变量名背后是什么*，分层覆盖进程环境、托管存储与 `.env` 文件。以上全部描述的都是这一半。
+本包是产品中负责存储与查询机密值的部分：密钥只存一次、处处按名引用，并可在任意时刻读取、检查或移除。它还保存持久化的凭据记录，让插件可以为自身 id 存储、更新或移除它持有的凭据。产品的默认组合已包含凭据存储；自定义组合只需加载本地存储包并给出文件路径。
 
-`CredentialKey` 回答的是*某个插件为某个 id 持有什么凭据*。这里没有任何东西可以分层——授权 grant 没有可供读取的环境——因此记录的存在与否就是全部事实，空值规则在此不适用：一条既无 key 也无环境值的 `api-key` 记录，陈述的是其拥有者确认该路由靠 ambient 认证，这属于已配置。
+### 何时使用
 
-键的形式是 `<scope>/<id>`，其中 `scope` 是**拥有该记录的插件的注册名**。scope 取拥有者而非领域，是因为 `grant` 的 payload 以其拥有者的格式写就：否则服务同一个提供方名称的两个插件会互相读到对方的 payload，而已卸载插件留下的记录也无法与仍在使用的区分开。`/` 同时让两种文法互斥，两个键空间因此不可能相撞。id 来自别处的消费方——settings dict 键、某个库自己的 provider id——应先问 `isCredentialKeySegment` 再构造键：文法之外的 id 不可能存过记录，应读作「没有存储任何东西」，而不是在寻址上抛错。
+只要配置需要与机密值绝缘，就使用凭据存储：需要同步、共享或渲染进配置界面的设置文件，或希望在不改配置的情况下轮换密钥的团队。当插件必须保存没有单一环境变量的凭据——登录流程产生的授权 grant，或提供方环境值——并希望配置界面能列出用户已授权什么时，请使用记录。配置界面能显示某个密钥或记录是否已设置、来自哪里、能否修改——但绝不显示值本身。如果只需要一个固定的环境变量，直接读该变量即可，无需存储。

+```
+
+用 `set` 存储密钥、用 `unset` 移除、用 `describe` 检查状态、在操作需要时用 `resolve` 读取当前值。`describe` 报告密钥是否已设置、来自哪里、能否写入——它绝不返回值。
+
+### 存储、更新与移除记录
+
+插件按 `<scope>/<id>` 寻址每条记录——自身注册名加一个自选 id，例如提供方路由键——并读取、修改或移除它所持有的内容：
+
+```ts
+import type { Context } from '@deepseek-ai/cordis'
+import { credentialKey } from '@deepseek-ai/dsh-credentials'
+
+declare const ctx: Context
 
 const key = credentialKey('llm-pi-ai', 'openai-codex')   // <owner>/<id>, branded
-await ctx.credentials.readRecord(key)                    // CredentialRecord | undefined
+const hit = await ctx.credentials.readRecord(key)        // CredentialRecord | undefined
 await ctx.credentials.describeRecord(key)                // { configured, kind?, writable } — never the value
 await ctx.credentials.listRecords()                      // [{ key, kind }] — never values
 await ctx.credentials.modifyRecord(key, async () => ({ kind: 'grant', payload: { token: '…' } }))
 await ctx.credentials.deleteRecord(key)                  // no-op when absent
 ```
 
-`modifyRecord` 是唯一写路径，因为正确的写入依赖当前值：刷新 token 是「读—决定—替换」，变更函数必须看到写入取得独占那一刻的记录。独占跨进程成立，这正是防止两个进程同时轮换同一个 refresh token、丢掉先写那一个的机制。变更函数返回 `undefined` 表示保持原状，不写盘也不发通知。
+`modifyRecord` 是唯一写路径：它让你的变更函数看到写入取得独占那一刻的记录，返回 `undefined` 则保持原状。记录没有空值规则——一条既无 key 也无环境值的记录，陈述的是其拥有者确认了 ambient 认证——配置界面还可以枚举每条记录，显示你已授权什么，并找出已卸载插件留下的记录。
 
-`listRecords` 存在，尽管引用那一半刻意不提供枚举。引用可以从 settings schema（`apiKeyEnv` 字段）被发现；记录没有这条路径，无法枚举的界面就无法显示用户已授权了什么，也找不到已卸载插件留下的孤儿。
+### 在配置中使用密钥
 
-`grant` 记录的 `payload` 是不透明的：seam 从不读取、校验或重塑它。唯一约束是它能经受 JSON 往返，提供方在写入与读出两个方向都强制这一点——存储无法逐字读回的值会被拒绝，而不是有损地存下。
+settings 分节或 `cordis.yml` 条目按名引用密钥，而不是包含密钥本身——例如 LLM（大语言模型）适配器接受 `apiKeyEnv`：
 
-`credentials/reference-updated (ref)` 在提供方管理的来源发生已提交变更后触发——`set`、`unset` 或在存储中观察到的外部编辑。进程环境变量的变化不可观测，永不触发。消费方不需要该事件（它们按操作重新解析）；它服务于配置界面刷新「已配置」徽标。它的声明住在 client-safe 的 `./types` 子路径出口，与其点名的 `CredentialRef` 类型同处一处（包根继续 re-export 该类型），于是 Host 编译面之外的消费方读到的正是 Host 发射的那一份签名，而不必再写一遍。
+```yaml
+apiKeyEnv: DEEPSEEK_API_KEY
+```
 
-`set`/`unset` 的遮蔽规则有意采用明确报错的方式：当只读来源（本地提供方中即当前进程环境）正在提供该引用时，写入会表面成功而解析仍返回遮蔽值——seam 选择直接拒绝，并通过 `describe().writable` 让界面提前把该引用渲染为只读。
+需要该密钥的请求使用它当前存储的值，因此轮换密钥会作用于紧随其后的下一次请求——无需重启，无需改配置。
 
-## 提供方
+### 可能出错的地方
 
-[`dsh-credentials-local`](../credentials-local/README.zh.md) 把继承的进程环境叠加在其受管 `$DSH_HOME/.credentials.yaml` 文档之上，并以启动器的项目和用户 `.env` 层作为后备。该 seam 的接口为 keyring、辅助命令和 KMS 后端提供方预留了扩展空间；远端设置提供方永远不必携带机密。
+- **启动环境提供的密钥无法被覆盖**——`DEEPSEEK_API_KEY=… dsh`（或 CI 机密、容器 `-e`）在本轮运行中优先，并被报告为只读；请先在启动 shell 中清除该变量，再存储其他值。
+- **空值无法存储**——存储空字符串会被拒绝；请改为移除密钥。
+- **密钥值绝不会出现在配置界面或诊断信息中**——界面只显示密钥是否已设置、来自哪里、能否修改；值本身留在存储中。

+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释本包背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+一条准则，四个推论：
+
+- **配置只携带引用，绝不携带机密。** settings 分节或 `cordis.yml` 条目点名一个凭据；引用背后的值存放在提供方处。设置文档可以放心同步、放心渲染，`describe()` 无需持有值就能回答，轮换机密不触碰任何配置文件。
+- **消费方按操作解析。** 解析是一次按调用读取，无跨操作缓存；这次读取正是热更新机制。
+- **空的存储值等于不存在。** `resolve` 跳过它，`describe` 报告未配置——空白永远不会伪装成已配置的机密。
+- **记录是持久化的，存在即事实。** 记录按 `<scope>/<id>` 存储并跨重启保留；空值规则不适用，因此一条既无 key 也无环境值的 `api-key` 记录是有意陈述，而不是空白。
+- **监听器失败被包含。** `notifyUpdated` 扇出 `credentials/reference-updated`，保证每个监听器都会运行；同步抛出与异步拒绝都会被记录，不改变已提交操作的结果，`INVARIANT` 编码的失败除外——它们在所有监听器运行完毕后重新抛出。
+
+### credentials/reference-updated 事件
+
+`credentials/reference-updated (ref)` 在提供方管理的来源发生已提交变更后触发——`set`、`unset` 或在存储中观察到的外部编辑。进程环境变量的变化不可观测，永不触发。消费方不需要该事件（它们按操作重新解析）；它服务于配置界面刷新「已配置」徽标。
+
+`credentials/record-updated (key)` 在存储记录发生已提交变更后触发——一次确实写入的 `modifyRecord`、一次确实移除的 `deleteRecord`，或在存储中观察到的外部编辑。它保持独立事件，因为两个键文法互斥：一个监听器若在同一事件上同时收到两个空间，将无法分辨主体属于哪一边。
+
+### 记录写入与读取路径
+
+`modifyRecord` 是唯一写路径，因为正确的写入依赖当前值：刷新 token 是「读—决定—替换」，变更函数看到的是写入取得独占那一刻的记录——返回 `undefined` 则保持原状。独占在支持它的底层存储上跨进程成立，这正是防止两个进程同时轮换一个 refresh token、丢掉先写那一个的机制。读取与引用一侧对称，但绝不分层：没有任何东西能遮蔽记录，`grant` 的 payload 会原样返回给其拥有者，因为只有拥有它的插件能解释它。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Service Definition：`credentialRef`/`credentialKey` 品牌、`ResolvedCredential`/`CredentialInfo`/`CredentialRecordInfo`、覆盖两个键空间的抽象提供方、包含式扇出 |
+| [`src/types.ts`](src/types.ts) | 客户端安全类型面：`CredentialRef` 与 `CredentialKey` 品牌、存储记录联合类型、`credentials/reference-updated` 与 `credentials/record-updated` 事件声明 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件：`credentials/reference-updated` 只在凭据服务存活时触发 |
+
+### 客户端安全类型
+
+`./types` 子路径出口把事件声明与其点名的 `CredentialRef`、`CredentialKey` 品牌及存储记录联合类型放在一起，包根继续 re-export 它们。于是 Host 编译面之外的消费方读到的正是 Host 发射的那一份签名，而不必再写一遍。
+
+### 生命周期
+
+服务是提供方注册的 Cordis `Service`：释放挂载 fiber 会移除 `ctx.credentials`。不变式伴生插件检查 `credentials/reference-updated` 绝不在服务存活之前触发——释放后仍有发射意味着提供方把工作泄漏到了 teardown 完全停稳之后。

-An experimental provider-composition POC that places one filesystem/process execution world in an E2B Linux sandbox. E2B supplies only sandbox lifecycle and the two fundamental OS adapters; provider-neutral consumers build higher capabilities above them.
+## Summary
 
-| Package | ctx key | Role |
+The e2b group moves the agent's file and command work into a remote Linux sandbox: file reads and writes, shell commands, and terminals all run in one remote world instead of on your machine. Three packages work together — one provides the shared sandbox, one runs file operations in it, and one runs commands and terminals in it. Existing shell, terminal, and language-server features keep working unchanged once the family is enabled, so no E2B-specific tooling is needed. The harness process, model calls, and session state never move — only the execution world is remote, and the sandbox is ephemeral. It is an experimental POC, and no shipped composition enables it by default.

 |---|---|---|
-| [`e2b`](e2b/README.md) (`@deepseek-ai/dsh-e2b`) | `ctx.e2b` | Create one sandbox, prepare its working/runtime directories, expose the shared SDK handle, and delete it on timeout or disposal |
-| [`fs-e2b`](fs-e2b/README.md) (`@deepseek-ai/dsh-fs-e2b`) | `ctx.fs` | Implement the filesystem seam over E2B Filesystem APIs |
-| [`subprocess-e2b`](subprocess-e2b/README.md) (`@deepseek-ai/dsh-subprocess-e2b`) | `ctx.subprocess` | Implement executable lookup, managed process groups and stdio, remote spill files, and terminal sessions over E2B Commands and PTY APIs |
+| [`e2b`](e2b/README.md) | One shared remote Linux sandbox that file and command work runs in | `ctx.e2b` |
+| [`fs-e2b`](fs-e2b/README.md) | File reads, writes, edits, and listings inside the remote sandbox | `ctx.fs` |
+| [`subprocess-e2b`](subprocess-e2b/README.md) | Shell commands and interactive terminals inside the remote sandbox | `ctx.subprocess` |
 
-The existing [`dsh-bash-local`](../shell/bash-local/README.md), [`dsh-terminal-bash`](../terminal/terminal-bash/README.md), and [`dsh-lsp-stdio`](../lsp/lsp-stdio/README.md) need no E2B-specific forks. They delegate every execution-world operation to `ctx.fs` and `ctx.subprocess`, so mounting the two E2B adapters places their mutable work in the same sandbox.

-This boundary does not move the harness process, Cordis objects, model calls, agent/session state, session persistence, skills, higher-level protocol state, or E2B SDK buffers. The [portable execution-world decision](../../.agents/notes/implemented/architecture/2026-07-28-portable-execution-world-consumers.md) owns both the generic composition and this POC boundary.

-这是一个实验性提供方组合 POC，把一个文件系统／进程执行环境放进 E2B Linux 沙箱。E2B 只提供沙箱生命周期与两个基础 OS 适配器；提供方无关的消费方在其上构建更高层能力。
+## 概述
 
-| 包（package） | ctx 键 | 职责 |
+e2b 组把 agent（智能体）的文件与命令工作移入远程 Linux 沙箱：文件读写、shell 命令与终端都在同一个远程世界中运行，而不是在你的机器上。三个包协同工作——一个提供共享沙箱，一个让文件操作在其中运行，一个让命令与终端在其中运行。启用本家族后，现有的 shell、终端与语言服务器功能无需任何改动即可继续工作，因此不需要 E2B 专用工具。harness 进程、模型调用与会话状态永远不会移动——只有执行世界是远程的，而且沙箱是短暂的。这是一个实验性 POC，任何已发布的组合都不会默认启用它。

-Shared lifecycle owner for one E2B sandbox. The filesystem and subprocess adapters inject `ctx.e2b`, await its single SDK handle, and therefore inhabit the same remote Linux working tree and process world. The package pins `e2b@2.29.1`; the [family map](../README.md) lists the opt-in composition.
+## Summary
 
-## Configuration
+`dsh-e2b` provides one shared remote Linux sandbox for the E2B provider family: the agent's file operations, shell commands, and terminals all run inside this sandbox instead of on your machine. The sandbox is created when the family starts and deleted automatically when the configured lifetime expires or the app shuts down — anything it held disappears with it. You configure three things: an API key, a remote working directory, and the sandbox lifetime. Use it together with `dsh-fs-e2b` and `dsh-subprocess-e2b`; on its own it adds no user-visible features. Nothing here reaches the model, and no shipped composition enables this family by default.

+<a id="use-this-package"></a>
+## Use this package
+
+Use this package when you want the agent's file and command work to run in a remote Linux sandbox rather than on your machine. It is the foundation of the E2B family: with the filesystem and subprocess packages mounted, all of that work shares one remote working directory and process world.
+
+### When to choose it
+
+Choose the E2B family when work should be isolated from the host machine — for example, when you want the agent's file edits and command runs to happen somewhere disposable. Choose the local filesystem and subprocess packages when running on the host is fine. This package is invisible to the model and adds no request cost.
+
+### Minimal configuration
+
+Three settings matter: an API key (or the `E2B_API_KEY` environment variable), an absolute remote working directory, and the sandbox lifetime. A bad key, a relative working directory, or an invalid lifetime rejects startup before any remote work happens.
 
 ```yaml
-- id: e2b
-  name: '@deepseek-ai/dsh-e2b'
+- name: '@deepseek-ai/dsh-e2b'
   config:
+    apiKey: <E2B API key>
     cwd: /home/user/workspace
     timeoutMs: 300000
 
-- id: subprocess-e2b
-  name: '@deepseek-ai/dsh-subprocess-e2b'
-
-- id: fs-e2b
-  name: '@deepseek-ai/dsh-fs-e2b'
+- name: '@deepseek-ai/dsh-subprocess-e2b'
+- name: '@deepseek-ai/dsh-fs-e2b'
 ```
 
-`apiKey` is optional and otherwise reads `E2B_API_KEY`; the key configures the host SDK connection and is never installed in the sandbox. `cwd` defaults to `/home/user/workspace` and must be an absolute POSIX path. `timeoutMs` defaults to five minutes and controls the sandbox lifetime; expiry deletes the sandbox.
+| Field | Default | Meaning |
+|---|---|---|
+| `apiKey` | `E2B_API_KEY` | API key for the host SDK connection; never installed in the sandbox |
+| `cwd` | `/home/user/workspace` | Remote working directory the family shares; absolute POSIX path |
+| `timeoutMs` | `300,000` | Sandbox lifetime in milliseconds; the sandbox is deleted when it expires |
 
-## Lifecycle and ownership
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-e2b) is the exhaustive source for every accepted field and its JSDoc.
 
-Construction starts one sandbox creation. Before resolving `getSandbox()`, the service creates `cwd` and the private `cwd/.dsh-e2b` adapter-state directory, verifies that the reserved path is a real directory rather than a symlink or another file type, then sets it to mode `0700`. Each adapter-internal E2B command shell receives a fresh randomized root-level `HOME`, so the SDK's fixed login shell does not resolve profile files from the mutable user home before the control command.
+### What you get
 
-Disposal first prevents new handle acquisition, then awaits setup and deletes the sandbox. A `SandboxNotFoundError` means expiry or another owner already deleted it and is accepted as quiescence. Initial directory setup failure makes one deletion attempt; the configured E2B timeout bounds a second failure. Provider plugins must load after this owner and dispose before it.
+With this package mounted, file reads and writes, shell commands, and terminals all operate inside the sandbox's working directory, so the agent sees one consistent remote world: what it writes with the file features is what its commands can read, and vice versa. The remote working directory is created if it does not exist yet.
 
+### Starting and stopping the sandbox
+
+Loading the plugin starts the sandbox in the background; the filesystem and subprocess features are ready once it is up. The sandbox lives for the configured lifetime (default five minutes) unless the app stops first — in both cases it is deleted, so save anything you still need before then. If the sandbox disappears while running (expired or removed elsewhere), the family treats that as a clean end rather than an error.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the owner and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+- **One sandbox, one handle.** All adapters await the same `getSandbox()` promise, so filesystem and process operations share one remote Linux world.
+- **Secure by construction.** The sandbox is created with `secure: true` and `lifecycle: { onTimeout: 'kill' }`, so expiry always deletes it.
+- **Isolated control shells.** `e2bControlEnvs()` gives every internal command shell a fresh randomized `HOME`, and `quoteE2BShellArg()` preserves opaque arguments through the SDK's unavoidable `/bin/bash -l -c` layer.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `E2BRuntime` service, `Config` schema, validation, sandbox open and teardown |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; sandbox creation and teardown have one SDK promise and no independent event or mutable-data relationship) |
+
+### Lifecycle
+
+`open()` creates the sandbox, prepares `cwd` and the private runtime root, rejects a non-directory or symlink runtime root, and applies `chmod 700`. Disposal prevents new handle acquisition, awaits setup, and deletes the sandbox, accepting `SandboxNotFoundError` as quiescence. `getSandbox()` re-checks the disposed flag after awaiting readiness, so disposal racing readiness still rejects acquisition; an eager connection failure stays observed but does not reject plugin load, and `getSandbox()` surfaces it.
+
+### Setup failure handling
+
+Any directory-setup failure makes one deletion attempt and preserves the original error; a failed rollback is bounded by E2B's configured sandbox timeout (see the Dev Note). Provider plugins must load after this owner and dispose before it, because every adapter awaits the same handle.

+No direct invalidation: the owner contributes no request tokens and never mutates a request prefix, so provider cache reuse is unaffected.
 
 ## Known Limitations and Deferred Work
 
-- **This is not a whole-harness runtime** — Cordis services, agent/session state, session logs, LLM requests, skills, and SDK-side buffers stay in the host process.
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define when the E2B family is a poor fit or needs special operational care. They are current package constraints, not a task backlog.
+
+- **Not a whole-harness runtime** — Cordis services, agent/session state, session logs, LLM requests, skills, and SDK-side buffers stay in the host process.
 - **Sandbox state is ephemeral** — disposal and timeout delete the sandbox; reconnect, pause/leave retention, templates, volumes, and snapshots are outside this POC.
 - **No deployment platform is configured** — network policy, host-workspace synchronization, and sandbox discovery are outside this POC.
 - **`cwd` is a resolution convention, not containment** — adapters and commands can address other sandbox paths; E2B network access retains the base image's policy.

+
+#### Open: sandbox setup rollback
+
+The `open()` failure path makes a single deletion attempt and preserves the original setup failure. Retry state stays deferred unless a real double failure outlives E2B's configured sandbox timeout (TODO(e2b-setup-rollback)).

-一个 E2B 沙箱的共享生命周期所有者。文件系统与进程管理适配器注入 `ctx.e2b`，等待其唯一的 SDK 句柄，因此处于同一个远程 Linux 工作树与进程环境中。本包固定使用 `e2b@2.29.1`；可选组合见[包族索引](../README.zh.md)。
+## 概述
 
-## 配置
+`dsh-e2b` 为 E2B 提供方家族提供一个共享的远程 Linux 沙箱：agent（智能体）的文件操作、shell 命令与终端都在这个沙箱内运行，而不是在你的机器上。家族启动时沙箱会自动创建，并在配置的生命周期到期或应用关闭时自动删除——其中保存的一切都会随之消失。你需要配置三件事：API 密钥、远程工作目录与沙箱生命周期。请与 `dsh-fs-e2b`、`dsh-subprocess-e2b` 一起使用；单独挂载它不会带来任何用户可见的功能。这里的一切都不会触及模型，而且任何已发布的组合都不会默认启用本家族。

+## 使用本包
+
+当你希望 agent 的文件与命令工作在远程 Linux 沙箱而非你的机器上运行时，使用本包。它是 E2B 家族的基础：挂载文件系统与子进程包之后，所有这些工作都会共享同一个远程工作目录与进程环境。
+
+### 何时选择
+
+当工作应与宿主机器隔离时——例如你希望 agent 的文件编辑与命令运行发生在某个可丢弃的环境中——选择 E2B 家族。当在宿主上运行没有问题的时候，选择本地的文件系统与子进程包。本包对模型不可见，也不增加任何请求成本。
+
+### 最小配置
+
+三个设置很重要：API 密钥（或 `E2B_API_KEY` 环境变量）、绝对远程工作目录与沙箱生命周期。密钥错误、相对工作目录或无效生命周期都会在任何远程工作开始前拒绝启动。
 
 ```yaml
-- id: e2b
-  name: '@deepseek-ai/dsh-e2b'
+- name: '@deepseek-ai/dsh-e2b'
   config:
+    apiKey: <E2B API key>
     cwd: /home/user/workspace
     timeoutMs: 300000
 
-- id: subprocess-e2b
-  name: '@deepseek-ai/dsh-subprocess-e2b'
-
-- id: fs-e2b
-  name: '@deepseek-ai/dsh-fs-e2b'
+- name: '@deepseek-ai/dsh-subprocess-e2b'
+- name: '@deepseek-ai/dsh-fs-e2b'
 ```
 
-`apiKey` 可省略；省略时读取 `E2B_API_KEY`。该密钥只配置宿主 SDK 连接，绝不会安装进沙箱。`cwd` 默认为 `/home/user/workspace`，并且必须是绝对 POSIX 路径。`timeoutMs` 默认为 5 分钟并控制沙箱生命周期；超时会删除沙箱。
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `apiKey` | `E2B_API_KEY` | 宿主 SDK 连接的 API 密钥；绝不会安装进沙箱 |
+| `cwd` | `/home/user/workspace` | 家族共享的远程工作目录；必须是绝对 POSIX 路径 |
+| `timeoutMs` | `300,000` | 沙箱生命周期（毫秒）；到期后沙箱被删除 |
 
-## 生命周期与所有权
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-e2b)是每个受支持字段及其 JSDoc 的穷尽式真源。
 
-构造阶段会启动一次沙箱创建。服务在 `getSandbox()` 成功返回前，会创建 `cwd` 和私有的 `cwd/.dsh-e2b` 适配器状态目录，验证该预留路径是真实目录而非符号链接或其他文件类型，再把该目录的 mode 设为 `0700`。每个适配器内部的 E2B 命令 shell 都会获得一个位于根目录下、全新随机生成的 `HOME`，因此 SDK 固定使用的登录 shell 不会在控制命令之前解析可变用户主目录中的配置文件。
+### 你能得到什么
 
-资源释放会先阻止继续获取新句柄，再等待初始化完成，然后删除沙箱。`SandboxNotFoundError` 表示沙箱已因超时或被另一个所有者删除，因此可视为完全停稳。初始目录设置失败时会尝试删除一次；若该尝试也失败，则由已配置的 E2B 超时约束沙箱的存活时间。提供方插件必须在该所有者之后加载，并在其之前 dispose（资源释放）。
+挂载本包后，文件读写、shell 命令与终端都会在沙箱的工作目录内运行，因此 agent 看到的是一个一致的远程世界：它用文件功能写入的内容，正是它的命令能够读取的内容，反之亦然。远程工作目录若不存在，会自动创建。
 
+### 沙箱的启动与停止
+
+加载插件会在后台启动沙箱；文件系统与子进程功能在其就绪后即可使用。沙箱存活时间为配置的生命周期（默认五分钟），除非应用先停止——两种情况下沙箱都会被删除，因此请在此之前保存你仍需要的内容。如果运行期间沙箱消失（到期或被别处删除），家族会将其视为干净利落的结束，而不是错误。

+## 理解实现
+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释所有者背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+- **一个沙箱，一个句柄。** 所有适配器都等待同一个 `getSandbox()` promise，因此文件系统与进程操作共享同一个远程 Linux 世界。
+- **构造即安全。** 沙箱以 `secure: true` 和 `lifecycle: { onTimeout: 'kill' }` 创建，因此超时必定删除它。
+- **隔离的控制 shell。** `e2bControlEnvs()` 为每个内部命令 shell 提供全新随机生成的 `HOME`，`quoteE2BShellArg()` 则通过 SDK 不可避免的 `/bin/bash -l -c` 层保留不透明参数。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：`E2BRuntime` 服务、`Config` schema、校验、沙箱创建与拆除 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；沙箱创建与拆除只有一个 SDK promise，没有可交叉核对的独立事件或可变数据关系） |
+
+### 生命周期
+
+`open()` 创建沙箱、准备 `cwd` 与私有运行时根目录、拒绝非目录或符号链接的运行时根目录，并执行 `chmod 700`。资源释放会阻止新的句柄获取、等待初始化完成并删除沙箱，把 `SandboxNotFoundError` 视为完全停稳。`getSandbox()` 在等待就绪后重新检查 disposed 标志，因此与就绪发生竞态的资源释放仍会拒绝获取句柄；急切连接失败会保持可观察，但不会拒绝插件加载，`getSandbox()` 会公开该失败。
+
+### 初始化失败处理
+
+任何目录初始化失败都会尝试删除一次并保留原始错误；回滚失败由 E2B 配置的沙箱超时约束（见开发备注）。提供方插件必须在该所有者之后加载、并在其之前 dispose（资源释放），因为每个适配器都等待同一个句柄。

 # @deepseek-ai/dsh-fs-e2b
 
 English | [中文](README.zh.md)
 
-E2B implementation of the [`@deepseek-ai/dsh-fs`](../../fs/fs/README.md) provider contract. It has no config: load [`@deepseek-ai/dsh-e2b`](../e2b/README.md) first, then this service in place of `dsh-fs-local`. The provider uses the owner's remote cwd and SDK handle, so file tools observe the same world as E2B-backed Bash processes.
+## Summary
 
-## Behavior
+`dsh-fs-e2b` runs the agent's file operations inside the remote sandbox: the agent can read files, list directories, write new files, overwrite or edit existing ones, and get accurate metadata — all in the same remote world where its commands run. It needs no configuration; mounting it moves file work off the host machine. Use it together with `dsh-e2b` and `dsh-subprocess-e2b` so files and commands share one remote working directory. The host machine's files are never touched, and results look to the model exactly like local file results. Choose the local filesystem package instead when files should live on the host.
 
-- **Remote identity and metadata** — relative paths resolve as POSIX paths against the caller cwd or `ctx.e2b.cwd`; GNU `realpath -mz` supplies canonical target identity without requiring the final file to exist, and ASCII/base64 plus strict NUL framing preserves newline and multibyte paths across the decoded SDK transport. `stat`, no-follow `lstat`, and stable one-level directory listings project E2B metadata into the filesystem seam; listings reuse returned metadata and resolve symbolic-link entries sequentially. Versions are opaque hashes of E2B metadata plus a per-write extended attribute.
-- **Execution-world paths** — canonical targets expose absolute POSIX process paths, percent-encoded `file:` URIs, and provider-owned containment checks, so generic subprocess consumers never parse E2B target ids or apply host path rules.
-- **UTF-8 reads** — whole reads and streamed reads preserve cross-chunk decoding, reject invalid UTF-8, and use the seam's 8192-byte NUL sample for binary detection. The model-facing tool still owns size selection and line windowing.
-- **Bounded raw-byte reads** — `readBytes` short-circuits on the stat size before any content transfer, then streams the remote object and cancels the stream at the first chunk past `maxBytes` (`FS_TOO_LARGE`), so neither an at-rest oversized file nor a post-stat grower is buffered whole in host memory. The empty-file quirk of the pinned SDK (content-length 0 returns `''` in stream format) yields an empty result.
-- **Atomic mutations** — writes create a random sibling staging directory, change it to mode `0700` before uploading content, and preserve an existing file's POSIX mode. Replacements publish through E2B's same-filesystem atomic rename. A guarded `createIfAbsent` publishes with remote `ln -T` instead, making the commit atomically no-replace even when a directory appears at the destination; metadata read from the staged file before that commit is projected to the target path for the returned version, so no fallible metadata request follows either commit point. E2B creates missing parent directories. Literal edits LF-normalize for matching, restore dominant CRLF storage, and serialize mutations per canonical target within the host process.
-- **Failures and cancellation** — E2B not-found, permission, abort, and other controller failures map to the existing `FsError` vocabulary. Cancellation is best-effort at earlier SDK request boundaries and checked immediately before publication. The signal is not forwarded into the rename or guarded-link commit, so cancellation cannot interrupt atomic publication or turn a committed write into a reported failure.

+## Use this package
+
+Use this package when the agent's file work — reading, writing, editing, listing — should happen inside the remote sandbox rather than on your machine. It is the filesystem half of the E2B family: what the agent writes here is what its commands can read in the same sandbox.
+
+### When to choose it
+
+Choose it when a composition already uses the E2B sandbox and you want file operations to run there. Choose the local filesystem package when files should stay on the host. There is no configuration to tune.
+
+### Mounting it
+
+Load the sandbox owner first, then this package; after that, file features operate on the sandbox:
+
+```yaml
+- name: '@deepseek-ai/dsh-e2b'
+- name: '@deepseek-ai/dsh-fs-e2b'
+```
+
+Mounting it does not copy or mirror your local files — the sandbox's working directory starts empty and fills as the agent works.
+
+### Reading files
+
+The agent can read a file's whole contents, stream large files, or read raw bytes up to a size cap. Binary files and files that are not valid UTF-8 text are refused with a clear message instead of being garbled; reads past the size cap fail with a message naming the limit.
+
+### Writing and editing files
+
+The agent can create files, overwrite them, or edit them by replacing a literal piece of text (optionally every occurrence), and can ask for a file to be created only if it does not exist yet. A write lands completely or not at all — a failed write never leaves a partial file. If the file changed since the agent last read it, the write is refused rather than clobbering the newer content, so two processes cannot overwrite each other's work unseen.
+
+### Paths in the sandbox
+
+Relative paths resolve against the caller's working directory or the sandbox's shared working directory, and are reported as the POSIX paths they are in the sandbox — what the agent reads and writes matches exactly what its commands see.
+

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the provider and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+- **One remote world.** Paths and contents stay in the sandbox; the host workspace is never copied, mounted, or reconciled.
+- **Atomic publication.** Every mutation commits through same-filesystem rename or a guarded link, and the returned version comes from the committed entry, so no fallible metadata request follows the commit point.
+- **Strict transport framing.** Canonical paths and contents cross the SDK as ASCII base64 with NUL framing, so newline and multibyte data survive arbitrary decoding boundaries.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `E2BFileSystem` provider, canonicalization, reads, atomic writes, error mapping |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; each operation returns the controller's committed result directly) |
+
+### Canonical paths and transport framing
+
+Relative paths resolve as POSIX paths against the caller `cwd` or `ctx.e2b.cwd`; GNU `realpath -mz` supplies canonical target identity without requiring the final file to exist, and ASCII base64 plus strict NUL framing preserves newline and multibyte paths across the decoded SDK transport. `stat`, no-follow `lstat`, and stable one-level directory listings project E2B metadata into the seam; canonical targets expose absolute POSIX process paths, percent-encoded `file:` URIs, and provider-owned containment checks.
+
+### Write path
+
+Writes create a random sibling staging directory, set it to mode `0700` before uploading content, and preserve an existing file's POSIX mode; replacements publish through E2B's same-filesystem atomic rename, and a guarded `createIfAbsent` publishes with `ln -T` so the commit is atomically no-replace even when a directory appears at the destination. The `dsh-version` extended attribute plus the committed entry's metadata form the returned version; literal edits LF-normalize for matching and restore the dominant CRLF style, and mutations serialize per canonical target. Staging-cleanup failures after commit never turn a successful write into a failure.
+
+### Failure and cancellation
+
+E2B not-found, permission, abort, and other controller failures map to the existing `FsError` codes (`FS_NOT_FOUND`, `FS_PERMISSION_DENIED`, `FS_ABORTED`, `FS_IO_ERROR`), while text and byte reads add `FS_NOT_TEXT` and `FS_TOO_LARGE`. Cancellation is checked at SDK request boundaries and immediately before publication, but the signal is never forwarded into the rename or guarded-link commit, so cancellation cannot interrupt atomic publication or turn a committed write into a reported failure.

 ## Model Experience
 
 Indirectly, through [`dsh-tool-fs`](../../fs/tool-fs/README.md), which renders remote UTF-8 content, directory results, mutation acknowledgements, and provider errors while E2B identity and transport remain internal.
 
 #### KV Cache effect
 
-No direct invalidation; the named consumer owns any request-prefix changes.
+No direct invalidation: `dsh-tool-fs` owns any request-prefix changes; the E2B transport never reaches a request.
 
 ## Known Limitations and Deferred Work
 
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define when the provider is a poor fit or needs special operational care. They are current package constraints, not a task backlog.
+
 - **No host synchronization** — an empty E2B cwd stays empty until a tool, command, or external process populates it; local files are neither uploaded nor reflected back.
 - **Mutation coordination is host-process-local** — `createIfAbsent` preserves a remote creator racing publication, but another harness connection or command can still race replacement; version guards detect only metadata changes represented by E2B.
 - **Reads reopen canonical targets by path** — a concurrent remote path replacement between resolution and stream opening is not fenced by a stable file handle; no observed product defect justifies a provider-specific bounded-read protocol in this POC.
 - **Whole-file mutation costs remain** — overwrite diffs and literal edits read complete files into host memory, and every operation incurs E2B controller latency.
 - **The POC targets E2B's default Linux image** — it relies on GNU `realpath`/`base64`/`chmod`, same-filesystem rename, streaming reads, and metadata extended attributes; custom templates are outside this POC.

 # @deepseek-ai/dsh-fs-e2b
 
 [English](README.md) | 中文
 
-[`@deepseek-ai/dsh-fs`](../../fs/fs/README.zh.md) 提供方约定的 E2B 实现。它没有配置：先加载 [`@deepseek-ai/dsh-e2b`](../e2b/README.zh.md)，再用本服务取代 `dsh-fs-local`。该提供方使用所有者的远程 cwd 和 SDK 句柄，因此文件工具观察到的环境与 E2B 后端 Bash 进程相同。
+## 概述
 
-## 行为
+`dsh-fs-e2b` 让 agent（智能体）的文件操作在远程沙箱内运行：agent 可以读取文件、列出目录、写入新文件、覆盖或编辑现有文件，并获得准确的元数据——全部发生在与它的命令相同的远程世界里。它不需要任何配置；挂载它就把文件工作从宿主机器上移走。请与 `dsh-e2b`、`dsh-subprocess-e2b` 一起使用，让文件与命令共享同一个远程工作目录。宿主机器上的文件永远不会被触及，模型看到的结果与本地文件结果完全一致。当文件应留在宿主上时，请选择本地的文件系统包。
 
-- **远程身份与元数据**：相对路径以调用方 cwd 或 `ctx.e2b.cwd` 为基准，按照 POSIX 路径解析；GNU `realpath -mz` 提供规范化目标身份，且不要求最终文件存在；ASCII/base64 加严格 NUL 分帧会在已解码的 SDK 传输中保留含换行符和多字节字符的路径。`stat`、不跟随链接的 `lstat` 和稳定的单层目录列表会把 E2B 元数据投影到文件系统 seam；目录列表会复用已返回的元数据，并依次解析符号链接条目。版本是 E2B 元数据与每次写入设置的扩展属性所组成的不透明哈希。
-- **执行环境路径**：规范化目标公开绝对 POSIX 进程路径、百分号编码的 `file:` URI，以及由提供方负责的包含关系检查，因此通用子进程消费方无需解析 E2B 目标 ID，也不会套用宿主路径规则。
-- **UTF-8 读取**：完整读取和流式读取会保持跨分片解码的连续性、拒绝无效 UTF-8，并使用 seam 的 8192 字节 NUL 样本检测二进制内容。面向模型的工具仍负责选择大小和行窗口。
-- **有界原始字节读取**：`readBytes` 在任何内容传输之前先按 stat 大小短路，然后流式读取远程对象，并在第一个超过 `maxBytes` 的分片处取消流（`FS_TOO_LARGE`），因此静态超限文件和 stat 后增长的文件都不会被完整缓冲进宿主内存。所钉版本 SDK 的空文件怪癖（content-length 为 0 时 stream 格式返回 `''`）产生空结果。
-- **原子变更**：写入会创建随机的同级暂存目录，在上传内容前将其 mode 改为 `0700`，并保留现有文件的 POSIX mode。替换操作通过 E2B 的同一文件系统原子重命名发布。带防护的 `createIfAbsent` 改用远程 `ln -T` 发布，即使目标位置出现目录，也能使提交具备原子且不替换的语义；系统会把提交前从暂存文件读取的元数据投影到目标路径，以生成返回的版本，因此任何一类提交点之后都不会再进行可能失败的元数据请求。E2B 会创建缺失的父目录。字面量编辑匹配时会规范化为 LF，存储时恢复占主导的 CRLF，并在宿主进程内按规范化目标串行执行变更。
-- **失败与取消**：E2B 的未找到、权限、中止及其他控制器故障会映射到现有 `FsError` 词汇。取消在更早的 SDK 请求边界上采用尽力而为语义，并在发布前立即检查。信号不会传入 rename 或防护链接提交，因此取消无法中断原子发布，也不会把已提交的写入报告为失败。
+## 目录
 
-该提供方不会复制、挂载或协调宿主工作区。把宿主路径用作 `cwd`，只会在远程创建一个拼写相同的目录。

+## 使用本包
+
+当 agent 的文件工作——读取、写入、编辑、列出——应在远程沙箱内而非你的机器上进行时，使用本包。它是 E2B 家族的文件系统半边：agent 在这里写入的内容，正是它的命令能在同一个沙箱中读取的内容。
+
+### 何时选择
+
+当组合已经使用 E2B 沙箱且希望文件操作在其中运行时，选择本包。当文件应留在宿主上时，选择本地文件系统包。这里没有需要调优的配置。
+
+### 挂载
+
+先加载沙箱所有者，再加载本包；之后文件功能就会作用于沙箱：
+
+```yaml
+- name: '@deepseek-ai/dsh-e2b'
+- name: '@deepseek-ai/dsh-fs-e2b'
+```
+
+挂载它不会复制或镜像你的本地文件——沙箱的工作目录从空开始，并随 agent 的工作逐渐被填充。
+
+### 读取文件
+
+agent 可以读取文件的完整内容、流式读取大文件，或在大小上限内读取原始字节。二进制文件与不是有效 UTF-8 文本的文件会被明确拒绝而不是乱码显示；超过大小上限的读取会以指明上限的消息失败。
+
+### 写入与编辑文件
+
+agent 可以创建文件、覆盖文件，或通过替换一段字面量文本（可选地替换所有出现处）来编辑文件，也可以要求仅在文件尚不存在时创建它。一次写入要么完整落地，要么完全不落地——失败的写入绝不会留下不完整的文件。如果文件在 agent 上次读取之后发生了变化，写入会被拒绝而不是覆盖较新的内容，因此两个进程不会在互不知情的情况下覆盖彼此的工作。
+
+### 沙箱中的路径
+
+相对路径会针对调用方的工作目录或沙箱共享工作目录解析，并按其在沙箱中的 POSIX 路径报告——agent 读写的内容与它的命令看到的内容完全一致。

+<summary>实现细节——点击展开</summary>
+
+本节解释提供方背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+- **一个远程世界。** 路径与内容都留在沙箱内；宿主工作区永远不会被复制、挂载或协调。
+- **原子发布。** 每次变更都通过同一文件系统 rename 或受防护链接提交，返回的版本来自已提交条目，因此提交点之后不会再有可能失败的元数据请求。
+- **严格的传输分帧。** 规范化路径与内容以带 NUL 分帧的 ASCII base64 形式跨越 SDK，因此换行与多字节数据能经受任意解码边界。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：`E2BFileSystem` 提供方、规范化、读取、原子写入、错误映射 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；每个操作都直接返回控制器的已提交结果） |
+
+### 规范化路径与传输分帧
+
+相对路径以调用方 `cwd` 或 `ctx.e2b.cwd` 为基准，按照 POSIX 路径解析；GNU `realpath -mz` 提供规范化目标身份，且不要求最终文件存在；ASCII base64 加严格 NUL 分帧会在已解码的 SDK 传输中保留含换行符和多字节字符的路径。`stat`、不跟随链接的 `lstat` 与稳定的单层目录列表会把 E2B 元数据投影到 seam；规范化目标公开绝对 POSIX 进程路径、百分号编码的 `file:` URI，以及由提供方负责的包含关系检查。
+
+### 写入路径
+
+写入会创建随机的同级暂存目录，在上传内容前将其 mode 设为 `0700`，并保留现有文件的 POSIX mode；替换操作通过 E2B 的同一文件系统原子重命名发布，带防护的 `createIfAbsent` 改用 `ln -T` 发布，即使目标位置出现目录，也能使提交具备原子且不替换的语义。`dsh-version` 扩展属性与已提交条目的元数据共同构成返回的版本；字面量编辑匹配时会规范化为 LF，并恢复占主导的 CRLF 风格，变更按规范化目标串行执行。提交后的暂存清理失败绝不会把一次成功的写入变成失败。
+
+### 失败与取消
+
+E2B 的未找到、权限、中止及其他控制器故障会映射到现有 `FsError` 错误码（`FS_NOT_FOUND`、`FS_PERMISSION_DENIED`、`FS_ABORTED`、`FS_IO_ERROR`），文本与字节读取则增加 `FS_NOT_TEXT` 与 `FS_TOO_LARGE`。取消在 SDK 请求边界与发布前立即检查，但信号永远不会传入 rename 或受防护链接提交，因此取消无法中断原子发布，也不会把已提交的写入报告为失败。

+
+这些限制说明本提供方何时不合适，或何时需要特别的运维注意。它们是当前包约束，不是任务积压。
 
 - **不提供宿主同步**：空的 E2B cwd 会一直为空，直到工具、命令或外部进程填充它；本地文件既不会上传，也不会同步回本地。
 - **变更协调仅限宿主进程内**：`createIfAbsent` 会保留与发布发生竞态的远程创建者所写入的文件，但另一个 harness 连接或命令仍可能与替换操作发生竞态；版本防护只能检测 E2B 元数据所体现的变更。
 - **读取会按路径重新打开规范化目标**：在解析与打开流之间若并发替换远程路径，该操作没有稳定文件句柄提供围栏；在该 POC 中，没有已观察到的产品缺陷能够证明提供方专用的有界读取协议值得引入。

-E2B implementation of the [`@deepseek-ai/dsh-subprocess`](../../subprocess/subprocess/README.md) seam. Load [`@deepseek-ai/dsh-e2b`](../e2b/README.md) first, then this service in place of `dsh-subprocess-local`. Existing Bash, PTY, and LSP consumers then execute in the shared remote sandbox without E2B-specific capability packages.
+## Summary
 
-## Configuration
+`dsh-subprocess-e2b` runs the agent's shell commands and terminals inside the remote sandbox: the agent can execute Bash, open interactive terminals, and read their output exactly as with local execution, while nothing runs on the host machine. Existing command, terminal, and language-server features keep working unchanged — no E2B-specific tools are needed. Secrets and host environment variables never leak into the sandbox: only environment entries the agent explicitly requests are passed along. Use it together with `dsh-e2b` and `dsh-fs-e2b` so commands, terminals, and files share one remote world. The main cost is remote latency — each command starts with a short asynchronous setup instead of launching instantly.

-- **Asynchronous remote start** — the synchronous seam returns a handle immediately while `Sandbox.commands.run(..., { background: true })` starts remotely. `pid` is `-1` until the wrapper publishes and the adapter validates its process-group id; stdin and ordinary observation wait for that publication. An owned startup signal aborts environment and private-state preparation before allocation; once allocation begins, cancellation waits for a provisional SDK handle it can clean.
-- **Execution-world coordinates** — `cwd` and private `runtimeRoot` come from the shared owner; executable lookup verifies absolute paths or resolves a bare name against the sandbox PATH plus explicit overrides, and rejects relative paths containing separators like every subprocess provider.
-- **Linux process groups** — a quoted wrapper starts each argv under `exec setsid --wait` and records its actual process-group id plus private status files beneath `ctx.e2b.runtimeRoot/processes`. The handle waits for that file instead of treating the SDK command PID as its published identity. Termination signals the negative recorded id with `SIGTERM`, waits the caller's `graceMs`, then escalates to `SIGKILL` and the SDK kill fallback; TERM delivery or probe failures also force that escalation. Process-table probes treat groups containing only zombie or dead entries as quiescent. Force cleanup succeeds only after a bounded probe finds the group empty; otherwise `waitForExit()` exposes a retryable failure, while proven quiescence makes later termination a no-op. Publication and monitoring failures apply the same cleanup transaction before rejecting. Service disposal rejects new starts, terminates and joins every retained process group, then awaits SDK settlement and private cleanup before the sandbox owner disposes.
-- **Environment boundary** — one trusted control-shell probe resolves the sandbox user's login home from its passwd entry and transports the sandbox environment as base64 ASCII for one strict UTF-8 decode; the wrapper then removes ambient `DSH_*` and credential-shaped (`*KEY*`, `*SECRET*`, `*TOKEN*`) names and restores every valid `spec.env` entry as an explicit caller opt-in. Empty names, `=`, and NUL framing violations reject before launch. Subsequent E2B command and PTY login shells receive a fresh randomized root-level `HOME` plus empty overrides for every scrubbed ambient name before user profiles can run; the requested argv receives the serialized environment afterward without changing the sandbox user's umask. Host ambient variables never enter the sandbox implicitly. Private environment files are removed after consumption, and failed command or terminal setup removes its private state before rejecting.
-- **Stdio projection** — the remote wrapper branches raw bytes into optional bounded spill files, frames each live chunk as newline-delimited base64 ASCII, and the host incrementally restores bytes across arbitrary SDK callback boundaries. Pipe mode writes those bytes to host Node streams; inherit mode writes them to the harness process streams; collect mode retains a bounded host tail with offset reads. The wrapper publishes the direct command status before waiting for inherited writers. For collect or inherit output, the adapter disconnects an incomplete SDK stream after `graceMs`, withholds its partial spill, and returns that status while retaining the remote group for `waitForExit()` and termination. Natural raw-pipe completion instead awaits lossless transport and preserves backpressure; explicit termination destroys the host pipes and releases blocked output before remote cleanup. Batch and streaming stdin use the SDK handle.
-- **Terminal sessions** — `spawnTerminal()` uses E2B's byte PTY API, installs the exact argv and scrubbed environment through private mode-`0600` files, reports the foreground process group, sends real signals, and tears down every live group in the remote terminal session through one retryable awaited `terminate()`; termination rejects new handle operations, aborts and joins in-flight writes, inspections, and signals, and treats zombie-only groups as quiescent. A private random output boundary discards the E2B bootstrap shell's prompt and echoed runner command while preserving every requested-process byte, including its first prompt. Terminal output is pushed to the handle's stream without awaiting host backpressure: a flowing consumer (the PTY backend attaches one at construction) folds bytes into its own bounded state, while a paused consumer buffers in host memory. PTY allocation is awaited through handle publication before cancellation is observed, so owned rollback can clean the published handle. Setup and teardown own the private state transaction, abort pending setup during service disposal, and fence publication; sandbox disposal or timeout bounds a setup rollback that also fails. Prompt detection, scrollback, readiness, and owner policy remain in `dsh-terminal-bash`.
-- **Sandbox disappearance** — `SandboxNotFoundError` during process or terminal liveness, termination, rollback, or disconnect proves the remote execution world cannot retain work, so cleanup treats it as quiescent; unrelated failures remain observable.

+## Use this package
 
+Use this package when the agent's shell commands and terminals should run inside the remote sandbox rather than on your machine. It is the command half of the E2B family: commands, terminals, and files share one remote world.
+
+### When to choose it
+
+Choose it when a composition already uses the E2B sandbox and you want commands and terminals to run there. Choose the local subprocess package for host execution. Tooling that needs a process id immediately — for example the ACP child backend — cannot use this package.
+
+### Configuration
+
+The only setting is how often the package checks a running command's status; the default suits most deployments, and raising it reduces remote requests at the cost of slightly slower exit detection.
+
+| Field | Default | Meaning |
+|---|---|---|
+| `pollMs` | `20` | How often the package checks a running command's status, in milliseconds |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-subprocess-e2b) is the exhaustive source for every accepted field and its JSDoc.
+
+### Running commands
+
+The agent can run a command in the sandbox with a working directory and environment, choose how its output is delivered (streamed live, captured up to a size cap, or routed to the app's own output), and stop it if it hangs — a stop first asks the command to exit politely, then force-kills it after a short grace, so a stuck command cannot leak. Very large output can be saved to a file in the sandbox so the agent can read it later. The command's exit code is reported normally; if the sandbox vanishes while a command runs, the command is treated as ended rather than erroring.
+
+### Using terminals
+
+The agent can open an interactive terminal in the sandbox, send input, read output, and signal programs running in it — prompts, interactive tools, and full-screen programs behave as they do locally. Terminal features like scrollback and readiness detection are provided by the terminal tooling, which works unchanged.
+
+### Keeping the environment clean
+
+Commands run with a clean, sandbox-native environment: host variables and values that look like credentials are not passed in implicitly, and only entries the agent explicitly requests are set. This keeps secrets out of the sandbox.
+
+### If the sandbox disappears
+
+The sandbox is ephemeral: if it is deleted while commands or terminals are running — through expiry, shutdown, or removal elsewhere — the affected commands are treated as ended cleanly. Do not rely on work surviving the sandbox.
+
+The default sandbox image ships with the runtime and utilities command work needs: `node`, `bash`, `setsid`, `ps`, `awk`, `tr`, `env`, `base64`, `chmod`, `tee`, `head`, `rm`, `kill`, `id`, and `getent`.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the provider and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+- **Deferred remote identity.** The synchronous seam never blocks on the network: the handle publishes its real process-group id asynchronously, and the wrapper's private files are the authority for pid, exit code, and spill validity.
+- **One teardown ladder.** Termination, rollback, and disposal share one process-group signal path — `SIGTERM`, then `SIGKILL` plus the SDK kill fallback — and treat proven quiescence as final.
+- **Environment is explicit.** Nothing from the host and nothing credential-shaped enters the sandbox implicitly; every ambient value is scrubbed and every `spec.env` entry is an explicit opt-in.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `E2BSubprocessRuntime`, `Config`, spawn and spawnTerminal, disposal |
+| [`src/process.ts`](src/process.ts) | `E2BSubprocessHandle`: remote wrapper, publication, termination, output projection |
+| [`src/terminal.ts`](src/terminal.ts) | `E2BTerminalHandle`: PTY allocation, session teardown |
+| [`src/environment.ts`](src/environment.ts) | Remote environment probe, scrubbing, serialization |
+| [`src/output.ts`](src/output.ts) | Base64 decoder and bounded output readers |
+| [`src/remote.ts`](src/remote.ts) | Shared control-shell helpers: option shaping, poll ticks, group signalling |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; live remote handles are private teardown ownership) |
+
+### Remote wrapper
+
+The bootstrap resolves its own tools from the sandbox PATH, refuses any missing or non-executable path, execs through `env -i` and `setsid --wait`, publishes the process-group id and exit code to private files beneath `ctx.e2b.runtimeRoot/processes`, and redirects stdout and stderr through base64 encoders that emit a reserved completion frame; `tee` and `head -c` bound optional spill files.
+
+### Process identity and publication
+
+The synchronous seam returns a handle immediately while the command starts asynchronously; `pid` stays `-1` until the wrapper publishes its process-group id and the adapter validates it, and stdin plus ordinary observation wait for that publication. A startup signal aborts environment and private-state preparation before allocation; once allocation begins, cancellation waits for a provisional SDK handle it can clean.
+
+### Environment boundary
+
+One trusted control-shell probe resolves the sandbox user's login home from its passwd entry and transports the sandbox environment as base64 ASCII for one strict UTF-8 decode; the wrapper then removes ambient `DSH_*` and credential-shaped (`*KEY*`, `*SECRET*`, `*TOKEN*`) names and restores every valid `spec.env` entry as an explicit caller opt-in. Empty names, `=`, and NUL framing violations reject before launch; subsequent command and PTY login shells receive a fresh randomized root-level `HOME` plus empty overrides for every scrubbed ambient name before user profiles can run. Private environment files are removed after consumption.
+
+### Output handling
+
+The remote wrapper branches raw bytes into optional bounded spill files and frames each live chunk as newline-delimited base64 ASCII; the host restores bytes across arbitrary SDK callback boundaries. Pipe mode writes to host Node streams, inherit mode to the harness process streams, and collect mode retains a bounded host tail with offset reads. For collect or inherit output, an incomplete SDK stream is disconnected after `graceMs` with its partial spill withheld; natural raw-pipe completion awaits lossless transport and preserves backpressure. Batch and streaming stdin use the SDK handle.
+
+### Termination ladder
+
+Termination and rollback share one tolerant signal path (`signalRemoteGroups`), escalate `SIGTERM` to `SIGKILL` on grace expiry, use the SDK kill as a fallback, and prove quiescence with a bounded process-table probe before reporting success; zombie-only groups count as empty, and a `SandboxNotFoundError` is treated as quiescence.

 ## Known Limitations and Deferred Work
 
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define when the provider is a poor fit or needs special operational care. They are current package constraints, not a task backlog.
+
 - **The SDK still retains complete command output in host memory** — E2B `CommandHandle.stdout` and `.stderr` accumulate the base64 transport even when this adapter exposes bounded raw-byte tails, so the subprocess seam's normal host-memory bound is not achieved and transport retention is larger than the source stream.
 - **Synchronous-PID consumers are unsupported** — `pid` remains `-1` during remote startup; consumers that require a positive PID immediately, including the ACP child backend, cannot use this provider unchanged.
 - **Private state lives for the sandbox lifetime** — process directories and valid spill files remain under `.dsh-e2b` until the owner deletes the sandbox; this POC supplies no in-sandbox sweep.
-- **Control state shares the sandbox user's UID** — E2B runs every command as the same default user, so `0700`/`0600` modes cannot isolate `.dsh-e2b` control files from concurrently running sandbox processes. A background process could rewrite `pid`/`exit-code` or read a not-yet-consumed `environment` file. The adapter validates published values and refuses group ids whose negative form is unsafe to signal (`<= 1`), but real isolation needs an E2B per-command user or an out-of-band control channel.
-- **Numeric process identities are not reuse-fenced** — E2B exposes numeric PID/PGID PTY input, signalling, and cleanup operations but no atomic identity-bound alternative. The adapter minimizes host round trips and live coverage exercises the reproducible stale-interrupt overlap; replacement is deferred until E2B adds an identity primitive or a failure demonstrates a narrower protocol.
-- **The initial environment probe inherits sandbox defaults** — E2B merges command overrides with default environment entries, so the probe cannot blank unknown credential-shaped names before enumerating them. A same-UID untrusted process already in the sandbox could inspect that short-lived control shell; this POC therefore does not support secrets in sandbox-default environment variables and requires an E2B replacement-environment primitive to close the gap.

 - **E2B exposes no signal fact** — an adapter-requested `SIGTERM` or `SIGKILL` is reported only when no wrapper-published direct exit code wins; every unrequested SDK exit remains an exit code, including values equal to `128 + signal`.
 - **Exact terminal stdin-wait inspection is unavailable** — E2B exposes the foreground process group but not the syscall evidence needed to prove it is waiting on fd 0, so the generic PTY backend falls back to controlled prompt markers and bounded silence.
 - **Linux utility and E2B transport semantics are assumed** — there is no Windows, escaped-session recovery, or network-partition fidelity layer.

+
+This Dev Note is working context for maintainers: open questions and directions that are not decided. It is explicitly non-authoritative — shipped behavior, limits, and accepted rationale live in the sections above and the package code.
+
+#### Open: numeric process identities
+
+E2B exposes numeric PID/PGID input, signalling, and cleanup operations without an atomic identity-bound alternative. The adapter minimizes host round trips and defers a replacement until E2B adds an identity primitive or a failure demonstrates a narrower protocol (TODO(e2b-pgid-identity)).
+
+#### Open: replacement environments and status observation
+
+The initial environment probe inherits sandbox defaults because E2B merges command overrides, and collect/inherit command status needs control-plane polling because E2B cannot observe direct-command exit independently of descendant-held output. Both close only with new E2B primitives (TODO(e2b-replace-environment), TODO(e2b-status-watch)).

+## 概述
 
-## 配置
+`dsh-subprocess-e2b` 让 agent（智能体）的 shell 命令与终端在远程沙箱内运行：agent 可以执行 Bash、打开交互式终端并读取其输出，体验与本地执行完全一致，而宿主机器上什么都不会运行。现有的命令、终端与语言服务器功能无需任何改动即可继续工作——不需要 E2B 专用工具。密钥与宿主环境变量绝不会泄漏进沙箱：只有 agent 显式请求的环境条目才会传入。请与 `dsh-e2b`、`dsh-fs-e2b` 一起使用，让命令、终端与文件共享同一个远程世界。主要代价是远程延迟——每条命令都要经过一段短暂异步初始化，而不是立即启动。

-- **异步远程启动**：同步 seam 会立即返回一个句柄，同时由 `Sandbox.commands.run(..., { background: true })` 在远程启动进程。包装层发布进程组 ID 并由适配器完成验证之前，`pid` 为 `-1`；stdin 和常规观察会等待该发布。自有启动信号会在分配前中止环境和私有状态准备；分配开始后，取消会等待可清理的临时 SDK 句柄。
-- **执行世界坐标**：`cwd` 和私有 `runtimeRoot` 来自共享所有者；可执行文件查找会验证绝对路径，或根据沙箱 PATH 加显式覆盖来解析裸名称，并与所有 subprocess 提供方一致地拒绝含分隔符的相对路径。
-- **Linux 进程组**：带引号保护的包装层会在 `exec setsid --wait` 下启动每组 argv，并在 `ctx.e2b.runtimeRoot/processes` 下记录实际进程组 ID 和私有状态文件。句柄会等待该文件，而不会把 SDK 命令 PID 当作已发布的身份。终止操作以记录的负数 ID 发送 `SIGTERM`，等待调用方的 `graceMs`，再升级到 `SIGKILL` 和 SDK kill 回退；TERM 信号发送或探测失败也会强制触发该升级。进程表探测会把仅含僵尸或已死亡条目的进程组视为完全停稳。强制清理只有在有界探测发现进程组为空后才算成功；否则 `waitForExit()` 会公开可重试的失败，而已证明的完全停稳会让后续终止操作不再执行任何动作。发布失败与监控失败都会在拒绝前执行同一清理事务。服务 dispose（资源释放）会拒绝新的启动请求、终止并等待每个保留进程组退出，再等待 SDK 结算和私有清理完成，之后沙箱所有者才会释放沙箱。
-- **环境边界**：一次受信任的控制 shell 探测会从 passwd 条目解析沙箱用户的登录主目录，以 base64 ASCII 传输沙箱环境，再进行一次严格 UTF-8 解码；随后包装层移除环境中的 `DSH_*` 和形似凭据的名称（`*KEY*`、`*SECRET*`、`*TOKEN*`），并把每个有效的 `spec.env` 条目恢复为调用方显式选择。空名称、`=` 和违反 NUL 分帧规则的条目会在启动前被拒绝。在用户 profile 脚本运行前，此后的 E2B 命令 shell 与 PTY 登录 shell 会获得位于根目录下、全新随机生成的 `HOME`，并为每个被清理的环境变量名设置空值覆盖；之后，请求的 argv 会在不改变沙箱用户 umask 的前提下接收序列化环境。宿主环境变量绝不会隐式进入沙箱。私有环境文件在使用后会被删除；命令或终端设置失败时，会先删除其私有状态再拒绝。
-- **stdio 投影**：远程包装层先把原始字节分流到可选的有界 spill 文件，再把每个实时分片编码为换行分隔的 base64 ASCII 帧；宿主会跨任意 SDK 回调边界增量恢复字节。pipe 模式把这些字节写入宿主 Node 流；inherit 模式把字节写入 harness 进程流；collect 模式保留有界的宿主尾部，并支持基于偏移量读取。包装层会在等待继承管道的写入方之前发布直接命令状态。对于 collect 或 inherit 输出，超过 `graceMs` 后，适配器会断开未完成的 SDK 流，不公开其中不完整的 spill，并返回该状态，同时保留远程进程组供 `waitForExit()` 和终止操作使用。原始 pipe 自然完成时，会等待无损传输完成并保留背压；显式终止则会销毁宿主 pipe，并在远程清理前释放受阻的输出写入。批量 stdin 和流式 stdin 都使用 SDK 句柄。
-- **终端会话**：`spawnTerminal()` 使用 E2B 的字节 PTY API，以 mode 为 `0600` 的私有文件传入原样 argv 与清理后的环境，报告前台进程组，发送真实信号，并通过一项可重试且须等待的 `terminate()` 清理远程终端会话中仍存活的每个进程组；终止会拒绝新的句柄操作，中止并等待在途写入、检查和信号操作结算，并把仅含僵尸进程的进程组视为已经完全停稳。私有随机输出边界会丢弃 E2B 引导 shell 的提示符和回显的 runner 命令，同时保留请求进程的每个字节，包括其第一个提示符。终端输出推入句柄流时不等待宿主背压：流动的消费方（PTY 后端在构造时就挂上一个）把字节折叠进自身的有界状态，而暂停的消费方会在宿主内存中缓冲。在句柄发布前会一直等待 PTY 分配完成，之后才观察取消，以便由承担清理责任的回滚清理已发布句柄。setup 与 teardown 负责私有状态事务，在服务 dispose 期间中止待处理的 setup 并阻止发布；若 setup 回滚也失败，则由沙箱 dispose 或超时约束其存活时间。提示符检测、scrollback、就绪状态与所有者策略仍归 `dsh-terminal-bash` 所有。
-- **沙箱消失**：在进程或终端的存活探测、终止、回滚或断开连接期间出现 `SandboxNotFoundError`，证明远程执行环境无法保留工作，因此清理会将其视为完全停稳；其他故障仍可观察。

+## 使用本包
 
+当 agent 的 shell 命令与终端应在远程沙箱内而非你的机器上运行时，使用本包。它是 E2B 家族的命令半边：命令、终端与文件共享同一个远程世界。
+
+### 何时选择
+
+当组合已经使用 E2B 沙箱且希望命令与终端在其中运行时，选择本包。宿主执行请选择本地子进程包。需要立即获得进程 ID 的工具——例如 ACP（Agent Client Protocol）子进程后端——无法使用本包。
+
+### 配置
+
+唯一设置是包检查运行中命令状态的频率；默认值适合大多数部署，调大它可以减少远程请求，代价是退出检测略慢。
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `pollMs` | `20` | 包检查运行中命令状态的频率（毫秒） |
+
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-subprocess-e2b)是每个受支持字段及其 JSDoc 的穷尽式真源。
+
+### 运行命令
+
+agent 可以在沙箱中按指定的工作目录与环境运行命令，选择输出的交付方式（实时流式、在大小上限内捕获，或路由到应用自身的输出），并在命令卡住时停止它——停止会先礼貌地请求命令退出，短暂宽限期后再强制终止，因此卡住的命令不会残留。非常大的输出可以保存到沙箱中的文件里，供 agent 稍后读取。命令的退出码会正常报告；如果命令运行期间沙箱消失，该命令会被视为已结束而不是报错。
+
+### 使用终端
+
+agent 可以在沙箱中打开交互式终端、发送输入、读取输出，并向其中运行的程序发送信号——提示符、交互式工具与全屏程序的行为与本地完全一致。scrollback 与就绪检测等终端功能由终端工具提供，无需改动即可工作。
+
+### 保持环境干净
+
+命令在干净、沙箱原生的环境中运行：宿主变量与形似凭据的值不会被隐式传入，只有 agent 显式请求的条目才会被设置。这使密钥不会进入沙箱。
+
+### 如果沙箱消失
+
+沙箱是短暂的：如果命令或终端运行期间沙箱被删除——无论是到期、关闭还是被别处移除——受影响的命令会被视为干净地结束。请不要依赖能在沙箱中存续的工作。
+
+默认沙箱镜像自带命令工作所需的运行时与工具：`node`、`bash`、`setsid`、`ps`、`awk`、`tr`、`env`、`base64`、`chmod`、`tee`、`head`、`rm`、`kill`、`id` 与 `getent`。

+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释提供方背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+- **延后的远程身份。** 同步 seam 从不阻塞在网络请求上：句柄异步发布真实进程组 ID，包装层的私有文件是 pid、退出码与 spill 有效性的权威来源。
+- **单一终止阶梯。** 终止、回滚与资源释放共享同一条进程组信号路径——先 `SIGTERM`，再 `SIGKILL` 加 SDK kill 回退——并把已证明的完全停稳视为最终状态。
+- **环境必须显式。** 宿主内容与形似凭据的内容都不会隐式进入沙箱；每个环境值都会被清理，每个 `spec.env` 条目都是显式选择。
+
+### 源码地图

+| 文件 | 职责 |

+| [`src/index.ts`](src/index.ts) | 插件入口：`E2BSubprocessRuntime`、`Config`、spawn 与 spawnTerminal、资源释放 |
+| [`src/process.ts`](src/process.ts) | `E2BSubprocessHandle`：远程包装层、发布、终止、输出投影 |

+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；存活远程句柄是私有的拆除所有权） |
+
+### 远程包装层
+
+引导脚本会从沙箱 PATH 解析自身所需的工具，拒绝任何缺失或不可执行的路径，通过 `env -i` 与 `setsid --wait` 执行 exec，把进程组 ID 与退出码发布到 `ctx.e2b.runtimeRoot/processes` 下的私有文件，并把 stdout 与 stderr 重定向到带保留完成帧的 base64 编码器；`tee` 与 `head -c` 约束可选 spill 文件的大小。
+
+### 进程身份与发布
+
+同步 seam 会立即返回句柄，同时命令异步启动；`pid` 在包装层发布进程组 ID 且适配器验证通过之前保持 `-1`，stdin 与常规观察都等待该发布。启动信号会在分配前中止环境与私有状态准备；分配开始后，取消会等待可清理的临时 SDK 句柄。
+
+### 环境边界
+
+一次受信任的控制 shell 探测会从 passwd 条目解析沙箱用户的登录主目录，以 base64 ASCII 传输沙箱环境，再进行一次严格 UTF-8 解码；随后包装层移除环境中的 `DSH_*` 与形似凭据的名称（`*KEY*`、`*SECRET*`、`*TOKEN*`），并把每个有效的 `spec.env` 条目恢复为调用方显式选择。空名称、`=` 与违反 NUL 分帧规则的条目会在启动前被拒绝；在用户 profile 脚本运行前，此后的命令与 PTY 登录 shell 会获得位于根目录下、全新随机生成的 `HOME`，并为每个被清理的环境变量名设置空值覆盖。私有环境文件在使用后会被删除。
+
+### 输出处理
+

+The examples group provides the reusable agent spine for tests and custom deployments that need a concrete composition without assembling it by hand. Its `-demo` npm suffix marks it as support infrastructure rather than a product interface. ACP, SDK, and one-shot applications launch through the `acp`, `sdk` or `sdk-minimal`, and `headless` profiles. This group contains no application entrypoint.

 # @deepseek-ai/dsh-agent-spine-demo
 
 English | [中文](README.zh.md)
 
-The **default executor-less, UI-less agent spine** as ONE Cordis bundle plugin. It loads the fixed set of services every harness agent needs, including the local skill provider, and forwards the loop's `agents` list as its own config — so an app package composes a working agent by adding only an entry point and the swappable backends.
+## Summary
 
-Read this package for the whole plugin tree and its composition order.
+`dsh-agent-spine-demo` gives you a working agent in one plugin: mount it, add an LLM adapter and an executor, and you can run a full agent conversation — in-memory sessions with automatic titles, a system prompt with your persona and workspace instructions, tools for bash, skills, and background jobs, and a loop that runs turns with retries. You configure it in user terms: persona, tool order, workspace-context budget, which agents to pre-create, optional persisted goals, and background-job limits. It ships no UI, executor, or persistence backend, and it adds no prompts or tool schemas of its own — the model sees only what your configuration produces. Use it when you are building a headless, ACP, or JSON-RPC agent and want the common agent machinery without building it yourself. Read this package for what you get out of the box and what you must supply.

+## Use this package
+
+Use this bundle when you are building an agent without a UI and want the common machinery handled for you: sessions, prompts, tools, and the turn loop. The common path is explicit — mount the bundle with a workspace-context budget, add an LLM adapter and a bash executor as sibling plugins, and provide `agents` when your entry point pre-creates them. When everything is configured, your agent accepts a prompt and returns a completed answer while the process keeps its session in memory.
+
+### What the bundle includes
+
+Out of the box you get: in-memory sessions with automatic fallback titles; a system prompt assembled from your persona, the Harness identity, and optional workspace instructions; model-facing tools for bash, local skills, and background jobs; optional persisted goals the agent can create and track; and a loop that runs turns with provider-routed retries. Add a session-persistence provider when sessions must survive process exit. The full plugin list lives in the implementation section below.
+
+### What stays outside the bundle
+
+These pieces are yours to supply; the bundle leaves them out so each entry point can pick its own:
+
+- **The LLM adapter** — you add the provider that calls a model; pick `llm-deepseek`, `llm-pi-ai`, or `llm-replay`.
+- **Model-backed session-title providers** — you get deterministic fallback titles out of the box; add at most one model-based titling provider if you want smarter titles.
+- **The bash executor** — the bundle provides the bash tool; you add the executor that runs commands (`bash-local` or a sandboxed implementation).
+- **Non-local skill providers** — local skills load out of the box; add providers for embedded or remote catalogs if you need them.
+- **The entry point and per-app infrastructure** — headless, ACP, and JSON-RPC apps own transport and output choices; you pick the one that fits your deployment.
+
+### Minimal configuration
+
+The smallest working setup mounts the bundle with a workspace-context budget, plus an LLM adapter and an executor:

+
+`workspaceContext` is the one required field: give it a byte budget so workspace files load into the agent's context, or set `false` for hermetic prompts. `agents` defaults to none, so pass the agents you want running — or omit it when your entry point creates them on demand (the ACP app does this). You know the setup works when the agent answers a first prompt and its session is saved.
+
+| Field | Default | What it configures |
+|---|---|---|
+| `agents` | `[]` | which agents your entry point pre-creates; omit to create them on demand |
+| `maxParallelToolCalls` | agent-loop default | how many tool calls may run at once; `1` is serial |
+| `includeHarnessIdentity` | `true` | whether the system prompt names the DeepSeek Harness identity |
+| `includeRuntimeContext` | `true` | whether the agent's history includes dynamic runtime-context snapshots |
+| `persona` | `''` | the deployment persona text in the system prompt |
+| `toolOrder` | lexicographic | the order the model sees tools in |
+| `tools` | `{ mode: 'native' }` | how tools reach the model: native schemas, Code Mode, or both |
+| `dshHome` | `$DSH_HOME` or `~/.dsh` | the harness home used for the bash environment and local skill folders |
+| `sessionTitle` | example limits | fallback title limits: 5 words, 40 fallback bytes, 80 accepted bytes |
+| `workspaceContext` | required | byte budget for loading workspace files into context, or `false` |
+| `skills` | enabled | whether local skills load and the skill tool is available |
+| `toolBash` | mounted | the bash tool; set `false` when another plugin owns `bash` |
+| `jobs` | owner default | how many background jobs each owner may run at once |
+| `toolJobs` | mounted | the background-job control tools; `false` keeps jobs without the tools |
+| `invariants` | owner default | developer setting: which package checks run and which packages are filtered |
+| `goals` | unmounted | optional persisted goals the agent can create and track across turns |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-agent-spine-demo) is the exhaustive source for every accepted field and its source declaration.
+
+### Request retry and billing
+
+Provider requests are retried automatically: if a call fails, the agent tries again in a new numbered step. Retries can cost you — each attempt may be billed, and `always` mode retries without limit — so usage accounting stays at your entry point. The retry itself does not clutter the conversation; you see the successful result.

+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the bundle composes the spine and points at the code that realizes it; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Composition model
+
+`apply(ctx, config)` mounts each child plugin under the bundle fiber and forwards every config field to the child that owns it. Cordis pends each fiber on its `inject` declarations until the services it needs exist, so load order is irrelevant to correctness; the listing below mirrors dependency layering for readability. `pickSpineConfig()` copies only the bundle-owned fields from an app config, so entry-point settings never leak into the spine; conflicting `dshHome` values fail during composition because local skills and the managed bash environment must share one harness home. The retry policy keeps retry status, provider errors, and failed partial chunks outside model history, and it reconstructs a retried request with its prior prefix intact so provider caches stay reusable.

-## What it deliberately leaves OUTSIDE the bundle
+### Why a code bundle, not a shared YAML include
 
-The spine is everything COMMON to every entry point. The swappable and entry-point-coupled pieces stay out, picked by whatever loads the bundle:
+A YAML include can deduplicate config but cannot own a bin or provide entry-point defaults; the ACP app package makes protocol-pure stdout wiring the default, though a leaf can still add an unsafe logger. Bundle children register services in the root isolate-keyed store, so injected leaf siblings see them without load-order coupling.
 
-- **the LLM adapter** — the bundle ships the abstract `llm` service; the leaf registers a concrete adapter on `ctx.llm` (`llm-deepseek`, `llm-pi-ai`, `llm-replay`).
-- **model-backed session-title providers** — the bundle mounts the fallback service with overridable example limits (5 words, 40 fallback bytes, 80 accepted-title bytes); a leaf may opt into exactly one first-prompt or all-messages LLM provider.
-- **the bash executor** — the bundle ships `tool-bash` (the consumer schema); the leaf provides `ctx.shell` (`bash-local` or a sandboxed impl).
-- **non-local skill providers** — the bundle ships the skill registry, the local filesystem provider, and the `skill` tool; deployments can add other providers such as embedded or remote catalogs as siblings.
-- **entry point + per-app infrastructure** — headless, ACP, and JSON-RPC app packages own transport, stdout, and reload choices. `timer` stays in the spine because it is common and stdout-silent.
+### Invariant companions
 
-This applies the [Service Definition / Service Provider / Consumer separation](../../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.md) at the composition level: the bundle owns the shared spine, the leaf owns the backends, the app package owns the entry point.
+The bundle mounts the invariant registry and its four package companions (`session`, `agent`, `scope`, `agent-loop`). `invariants.enabled: false` or package filters suppress the checks but do not remove the service or companion registrations; Session's always-on validation and freezing are separate. The package's own companion ([`src/invariant.ts`](src/invariant.ts)) installs no runtime invariant because this composition package owns no independent event stream or mutable data.
 
-## Config
+### Source map
 
-```ts
-import type { Config } from '@deepseek-ai/dsh-agent-spine-demo'
-// { agents?, maxParallelToolCalls?, includeHarnessIdentity?, includeRuntimeContext?, persona?, toolOrder?, tools?, dshHome?, sessionTitle?, skills?, workspaceContext, toolBash?, jobs?, toolJobs?, goals?, invariants? }
-// workspaceContext requires { maxBytes } or false; the other owner schemas supply defaults.
-```
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `Config` schema, `pickSpineConfig()`, `apply()` mounting every child |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; composition wiring is covered by tests) |
 
-The bundle forwards each field to the child that owns it. App packages supply any pre-created agents: headless and JSON-RPC compositions create `main`, while the ACP app creates agents on demand at `session/new`. `includeRuntimeContext: false` suppresses all dynamic context snapshots for fresh sessions without disabling their policy services. Prompt, tool, title, skill, agent-instructions, invariant, goal, and task settings retain the schemas and defaults documented by their owning packages; `jobs.maxConcurrentJobsPerOwner` configures the local provider independently of the model-facing `toolJobs` controls. `pickSpineConfig()` copies only fields owned by this bundle, and conflicting `dshHome` values fail during composition.
+</details>
 
-For example, `{ invariants: { enabled: true, package_allowlist: ['^@deepseek-ai/dsh-'], package_blocklist: ['agent-loop$'] } }` keeps the package-owned companions mounted but suppresses the blocked owner. Blocklist matches override allowlist matches; see [`dsh-invariants`](../../runtime-diagnostics/invariants/README.md) for regex and lifecycle rules.

-## Why a code bundle, not a shared YAML include
+<a id="further-exploration"></a>
+## Further Exploration
 
-A YAML include can deduplicate config but cannot own a bin or provide entry-point defaults. The ACP app package makes protocol-pure stdout wiring the default, though a leaf can still add an unsafe logger. Bundle children register services in the root isolate-keyed store, so injected leaf siblings see them without load-order coupling.
+Read these pages when the package-level contract is not enough. They move from the sibling demo apps to the subsystems this spine mounts and the exhaustive configuration.
 
-The retry policy may repeat a failed request in a new numbered step. Retry status, provider errors, and failed partial chunks stay outside model history; each provider attempt can still incur billing, always mode has no attempt limit, entry points derive usage across every logged step, and the reconstructed request preserves the prior prefix for provider cache reuse.

 ## Model Experience
 
-Indirectly, through `dsh-system-prompt`, `dsh-tool-skill`, `dsh-tool-bash`, `dsh-tools`, and `dsh-llm-retry`, plus `dsh-tool-goal` and goal-round prompts when `goals` is enabled. The bundle adds no model-bound wrapper content of its own.
+Indirectly, through the model-facing child plugins the bundle mounts — `dsh-system-prompt`, `dsh-tools`, `dsh-tool-skill`, `dsh-tool-bash`, `dsh-tool-jobs`, and `dsh-llm-retry`, plus `dsh-tool-goal` and the goal-round driver's prompts when `goals` is enabled; the bundle adds no model-bound wrapper content of its own.
 
 #### KV Cache effect
 
-No direct invalidation; the named consumer owns any request-prefix changes.
+The bundle adds no request-prefix content of its own; provider cache reuse depends on the mounted consumers' contributions, and `dsh-llm-retry` reconstructs a retried request with its prior prefix intact.
 
 ## Known Limitations and Deferred Work
 
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define when the bundle is a poor fit or needs special operational care. They are current package constraints, not a comparison with other composition approaches or a task backlog.
+
 - **Most of the spine set is fixed in code** — `apply()` always mounts the core services; config can omit bundled goals, skills, bash, and task-control tools, but swapping the loop or dropping another spine member means composing a different bundle.
 - **The invariant service and companions remain fixed members** — `invariants.enabled: false` or package filters suppress checks but do not remove the service or companion registrations; Session's always-on validation and freezing are separate.
+- **Retry can duplicate provider billing** — each provider attempt may incur billing, and `always` mode has no attempt limit; usage accounting stays with the entry point.

+
+This Dev Note is working context for maintainers; it is explicitly non-authoritative — shipped behavior, limits, and accepted rationale live in the sections above and the package code.
+
+The fallback title limits (5 words, 40 fallback bytes, 80 accepted-title bytes) are an overridable example policy owned by this bundle rather than by `dsh-session-title`; an entry point that needs different bounds passes its own `sessionTitle` config. The `workspaceContext` field is required (not defaulted) because it changes model-visible input; keep that requirement if the field is ever re-shaped.

 # @deepseek-ai/dsh-agent-spine-demo
 
 [English](README.md) | 中文
 
-将**默认的不含执行器、不含 UI 的 agent（智能体）主干**作为一个 Cordis 组合包插件。它加载每个 harness agent 所需的固定服务集合，包括本地 skill（技能）提供方，并将循环的 `agents` 列表作为自身配置转发。因此，应用包只需添加入口和可替换后端，就能组合出可工作的 agent。
+## 概述
 
-阅读此包可了解完整插件树及其组合顺序。
+`dsh-agent-spine-demo` 用一个插件给你一个可工作的 agent（智能体）：挂载它、添加 LLM（大语言模型）适配器与执行器，即可运行完整的 agent 对话——带自动标题的内存会话、包含你的 persona 与工作区指令的系统提示词、bash、skill 与后台任务工具，以及带自动重试的运行轮次循环。你可以用用户术语配置它：persona、工具顺序、工作区上下文预算、预创建哪些 agent、可选持久目标与后台任务上限。它不附带 UI、执行器或持久化后端，且不添加任何自己的提示词或工具 schema——模型只看到你的配置产生的内容。当你构建无头、ACP（Agent Client Protocol）或 JSON-RPC agent、希望复用通用 agent 机制而不必自己搭建时使用它。阅读本包可了解开箱即得的内容，以及需要你自行提供的内容。
 
-## 它加载的插件树
+## 目录
 
-`apply(ctx, config)` 将以下每个插件挂载为组合包 fiber 的子节点：

+<a id="use-this-package"></a>
+## 使用本包
+
+当你在构建不带 UI 的 agent、希望会话、提示词、工具与轮次循环这些通用机制由本包代劳时使用此组合包。常用路径是显式的——用工作区上下文预算挂载组合包，把 LLM 适配器与 bash 执行器作为同级插件添加，并在入口预创建 agent 时提供 `agents`。配置完成后，你的 agent 就能接受提示词并返回完成的答案，当前进程会把该会话保留在内存中。
+
+### 组合包包含的内容
+
+开箱即得：带自动后备标题的内存会话；由你的 persona、Harness 身份与可选工作区指令组装的系统提示词；bash、本地 skill 与后台任务等面向模型的工具；agent 可以创建与跟踪的可选持久目标；以及带提供方路由重试、运行轮次的循环。会话需要在进程退出后继续存在时，请添加会话持久化提供方。完整插件清单见下方实现章节。
+
+### 留在组合包外的内容
+
+以下部分需要你自行提供；组合包把它们留在外部，让每个入口都能自行选择：
+
+- **LLM 适配器**——你需要添加调用模型的提供方；可选择 `llm-deepseek`、`llm-pi-ai` 或 `llm-replay`。
+- **基于模型的会话标题提供方**——开箱即用确定性后备标题；若想要更智能的标题，可以恰好添加一个基于模型的标题提供方。
+- **bash 执行器**——组合包提供 bash 工具；你需要添加实际运行命令的执行器（`bash-local` 或沙箱化实现）。
+- **非本地 skill 提供方**——本地 skill 开箱即用；需要嵌入式或远程目录时，可以添加相应提供方。
+- **入口与各应用基础设施**——无头、ACP 与 JSON-RPC 应用负责传输与输出选择；请选择适合你部署的那一个。
+
+### 最小配置
+
+最小可用配置是：用工作区上下文预算挂载组合包，再加上 LLM 适配器与执行器：
+
+```yaml
+- name: '@deepseek-ai/dsh-agent-spine-demo'
+  config:
+    workspaceContext:
+      maxBytes: 4096
+- name: '@deepseek-ai/dsh-llm-deepseek'   # concrete adapter for ctx.llm
+- name: '@deepseek-ai/dsh-bash-local'     # executor for ctx.shell
 ```
-@deepseek-ai/cordis-plugin-timer  timer service (writes nothing to stdout)

-@deepseek-ai/dsh-session          event-sourced session log + store
-@deepseek-ai/dsh-session-title    log-backed title service + deterministic fallback
-@deepseek-ai/dsh-system-prompt    prompt-section + tool-schema assembly
-@deepseek-ai/dsh-tools            registry + guarded pre/around/post/final-result pipeline
-@deepseek-ai/dsh-skill            skill provider registry
-@deepseek-ai/dsh-skill-filesystem      local filesystem skill provider
-@deepseek-ai/dsh-agent            agent registry + initiator scope + agent/* events
-@deepseek-ai/dsh-goal             optional persisted same-session goal domain
-@deepseek-ai/dsh-tool-goal        optional model-facing goal controls
-@deepseek-ai/dsh-goal-round-driver     optional same-session goal-round driver
-@deepseek-ai/dsh-llm-retry        provider-routed request retry policy
-@deepseek-ai/dsh-jobs-local      generic background-job registry
-@deepseek-ai/dsh-invariants       configurable invariant registry service
+
+`workspaceContext` 是唯一必填字段：给它一个字节预算，工作区文件就会加载进 agent 上下文；设 `false` 则得到隔离提示词。`agents` 默认为空，因此请传入你想运行的 agent——或者当你的入口按需创建 agent 时省略它（ACP 应用就是这样）。当 agent 回答第一个提示词且会话被保存时，说明配置成功。
+
+| 字段 | 默认值 | 配置内容 |
+|---|---|---|
+| `agents` | `[]` | 你的入口预创建的 agent；按需创建时省略 |
+| `maxParallelToolCalls` | agent loop 默认值 | 同时运行的工具调用数；`1` 表示串行 |
+| `includeHarnessIdentity` | `true` | 系统提示词是否点名 DeepSeek Harness 身份 |
+| `includeRuntimeContext` | `true` | agent 历史是否包含动态运行时上下文快照 |
+| `persona` | `''` | 系统提示词中的部署 persona 文本 |
+| `toolOrder` | 字典序 | 模型看到工具的顺序 |
+| `tools` | `{ mode: 'native' }` | 工具如何到达模型：native schema、Code Mode 或两者 |
+| `dshHome` | `$DSH_HOME` 或 `~/.dsh` | bash 环境与本地 skill 目录使用的 harness 主目录 |
+| `sessionTitle` | 示例限制 | 后备标题限制：5 个词、40 个后备字节、80 个可接受字节 |
+| `workspaceContext` | 必填 | 加载工作区文件进上下文的字节预算，或 `false` |
+| `skills` | 启用 | 是否加载本地 skill 并提供 skill 工具 |
+| `toolBash` | 挂载 | bash 工具；当其他插件拥有 `bash` 时设 `false` |
+| `jobs` | 拥有者默认值 | 每个 owner 可同时运行的后台任务数 |
+| `toolJobs` | 挂载 | 后台任务控制工具；`false` 保留任务但不提供工具 |
+| `invariants` | 拥有者默认值 | 开发者设置：运行哪些包检查、过滤哪些包 |
+| `goals` | 不挂载 | agent 可创建并跨轮次跟踪的可选持久目标 |
+
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-agent-spine-demo)是每个受支持字段及其源声明的穷尽式真源。
+
+### 请求重试与计费
+
+提供方请求会自动重试：调用失败时，agent 会在新的编号步骤中重试。重试可能产生费用——每次尝试都可能计费，`always` 模式没有尝试次数上限——因此用量核算留在你的入口。重试本身不会弄乱对话；你看到的是成功的结果。

+
+本节解释组合包如何组装主干，并指出实现它的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 组合模型
+
+`apply(ctx, config)` 把每个子插件挂载到组合包 fiber 下，并把每个配置字段转发给拥有它的子插件。Cordis 会按 `inject` 声明挂起每个 fiber，直到其所需服务存在为止，因此加载顺序不影响正确性；下方的清单只是按依赖分层排列，便于阅读。`pickSpineConfig()` 只从应用配置中复制组合包拥有的字段，因此入口设置绝不会泄漏进主干；`dshHome` 值冲突会在组合时失败，因为本地 skill 与受管 bash 环境必须共享同一个 harness 主目录。重试策略让重试状态、提供方错误与失败的部分分片不进入模型历史，并重建保留先前前缀的重试请求，使提供方缓存保持可复用。

-## 有意留在组合包外的组件
+### 为何用代码组合包，而非共享 YAML include
 
-主干包含每个入口都共有的全部组件。可替换组件和与入口耦合的组件留在外部，由加载组合包的一方选择：
+YAML include 可以去重配置，却无法拥有 bin 或提供入口默认值；ACP 应用包默认接出协议纯净的 stdout 接线，但叶节点仍可添加不安全的 logger。组合包子节点把服务注册到根 isolate-keyed store，因此叶节点的同级插件无需依赖加载顺序即可通过注入看到它们。
 
-- **LLM（大语言模型）适配器**：组合包交付抽象 `llm` 服务；叶节点在 `ctx.llm` 上注册具体适配器（`llm-deepseek`、`llm-pi-ai`、`llm-replay`）。
-- **基于模型的会话标题提供方**：组合包挂载带可覆盖示例限制的后备服务（5 个词、40 个后备字节、80 个可接受标题字节）；叶节点可以恰好选用一个首消息或全消息 LLM 提供方。
-- **bash 执行器**：组合包交付 `tool-bash`（消费方 schema）；叶节点提供 `ctx.shell`（`bash-local` 或沙箱化实现）。
-- **非本地 skill 提供方**：组合包交付 skill 注册表、本地文件系统提供方和 `skill` 工具；部署可以把嵌入式目录或远程目录等其他提供方作为同级插件添加。
-- **入口与各应用基础设施**：无头、ACP（Agent Client Protocol）和 JSON-RPC 应用包负责传输、stdout 与重新加载选择。`timer` 保留在主干中，因为它是共有组件且不写 stdout。
+### 不变式配套插件
 
-这里在组合层应用 [Service Definition／Service Provider／Consumer 的职责分离](../../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.zh.md)：组合包拥有共享主干，叶节点拥有后端，应用包拥有入口。
+组合包挂载不变式注册表及其四个包配套插件（`session`、`agent`、`scope`、`agent-loop`）。`invariants.enabled: false` 或包筛选器会抑制检查，但不会移除服务或配套插件注册；Session 始终启用的校验与冻结是另一套机制。本包自己的配套插件（[`src/invariant.ts`](src/invariant.ts)）不安装任何运行时不变式，因为这个组合包不拥有独立事件流或可变数据。
 
-## 配置
+### 源码地图
 
-```ts
-import type { Config } from '@deepseek-ai/dsh-agent-spine-demo'
-// { agents?, maxParallelToolCalls?, includeHarnessIdentity?, includeRuntimeContext?, persona?, toolOrder?, tools?, dshHome?, sessionTitle?, skills?, workspaceContext, toolBash?, jobs?, toolJobs?, goals?, invariants? }
-// workspaceContext requires { maxBytes } or false; the other owner schemas supply defaults.
-```
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：`Config` schema、`pickSpineConfig()`、挂载所有子插件的 `apply()` |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式配套插件（无运行时不变式；组合接线由测试覆盖） |
 
-组合包将每个字段转发给拥有它的子节点。应用包提供预创建的 agent：无头和 JSON-RPC 组合会创建 `main`，ACP 应用则在 `session/new` 按需创建 agent。`includeRuntimeContext: false` 会为新建会话抑制所有动态上下文快照，但不禁用其策略服务。提示词、工具、标题、skill、工作区上下文、不变式、目标和任务设置沿用其所属包记录的 schema 与默认值；`jobs.maxConcurrentJobsPerOwner` 配置本地 Service Provider，并与面向模型的 `toolJobs` 控制工具相互独立。`pickSpineConfig()` 只复制该组合包拥有的字段，`dshHome` 值冲突会在组合时失败。
+</details>
 
-例如，`{ invariants: { enabled: true, package_allowlist: ['^@deepseek-ai/dsh-'], package_blocklist: ['agent-loop$'] } }` 会让包拥有的配套插件保持挂载，但抑制被阻止的拥有者。Blocklist 匹配优先于 allowlist 匹配；正则表达式与生命周期规则见 [`dsh-invariants`](../../runtime-diagnostics/invariants/README.zh.md)。

+## 进一步探索
 
-YAML include 可以去重配置，却无法拥有 bin 或提供入口默认值。ACP 应用包默认接出协议纯净的 stdout，但叶节点仍可添加不安全的 logger。组合包子节点把服务注册到根 isolate-keyed store，因此叶节点的同级插件无需依赖加载顺序即可通过注入看到它们。

-重试策略可能在新的编号步骤中重复失败的请求。重试状态、提供方错误和失败的部分分片不进入模型历史；每次提供方尝试仍可能产生计费；always 模式没有尝试次数上限；入口从所有已记录步骤推导用量；重建的请求保留先前前缀，以便复用提供方缓存。

 ## 模型体验
 
-模型通过 `dsh-system-prompt`、`dsh-tool-skill`、`dsh-tool-bash`、`dsh-tools` 和 `dsh-llm-retry` 间接获得体验；还会通过 `dsh-tool-goal` 与 Goal Round 提示词获得体验，前提是启用 `goals`。组合包自身不添加面向模型的包装内容。
+模型体验由组合包挂载的面向模型子插件间接提供——`dsh-system-prompt`、`dsh-tools`、`dsh-tool-skill`、`dsh-tool-bash`、`dsh-tool-jobs` 与 `dsh-llm-retry`，启用 `goals` 时还包括 `dsh-tool-goal` 与目标轮次驱动器的提示词；组合包自身不添加任何面向模型的包装内容。
 
 #### KV Cache 影响
 
-不会直接失效；上述消费方负责请求前缀的任何变更。
+组合包自身不添加请求前缀内容；提供方缓存复用取决于所挂载消费方的贡献，`dsh-llm-retry` 重建重试请求时会保留其先前前缀。
 
-## 已知限制与暂缓事项
+## 已知限制与延期工作
+
+<a id="known-limitations-and-deferred-work"></a>
+
+
+这些限制说明组合包何时不合适，或何时需要特别的运维注意。它们是当前包约束，不是与其他组合方式的对比，也不是任务积压。

-This group contains prototypes and internal-only Cordis plugins that use the repository's real runtime without joining an official release. Its packages are private, carry no stability or support promise, and retain the same engineering, security, documentation, lifecycle, testing, and snapshot requirements as release packages.
+## Summary
+
+The experimental group contains prototype capabilities that are not part of any official release: they run on the real harness, but their contracts can change and they carry no support promise. The group holds Agent Teams plus the browser-worker runtime and image packer used by preview deployments. Use these packages to try an unreleased capability; they carry no stability promise, and released products must not depend on them.

-Implicit-root Agent Teams domain. `ctx.agentTeams` owns a flat Lead/teammate roster, a durable peer mailbox, and a shared task DAG in the Lead Session log. The [Agent Teams Agent Note](../../../.agents/notes/implemented/feature/2026-08-05-agent-teams.md) owns the coordination and isolation decisions; the [Team subsystem catalog](../../../docs/subsystems/agent-team.md) records the literal durable shapes and service API.
+## Summary
 
-## Config
+`dsh-experimental-agent-team` turns one coding session into a small working team: the session's agent becomes the Lead, creates named teammates for delegated work, exchanges durable messages with them, and tracks shared tasks on a common board. Messages and task state survive crashes, reloads, and interruptions, so a teammate that was offline receives its queued messages when it resumes. It provides no tools of its own — mount the sibling `dsh-experimental-tool-agent-team` so the model can create teammates, message them, and use the task board. It is experimental: excluded from official releases, carries no stability promise, and needs durable session storage to activate.

+## Use this package
+
+Add this package to a composition when one agent should run a small team of named helpers in its own working directory, with messages and task state that survive crashes and restarts. It ships no tools of its own: mount it together with `@deepseek-ai/dsh-experimental-tool-agent-team` so the model can create teammates, message them, and use the task board.
+
+### When to choose it
+
+Choose it when several agents must cooperate on one shared workspace and their roster, messages, and task state must survive crashes and restarts. Avoid it when teammates need separate working directories, when several processes must coordinate over one team, or when a task owner should be released automatically — none of those are supported. The team features need durable session storage to activate.
+
+### Smallest working setup
+
+<a id="smallest-working-setup"></a>
+
+The smallest addition to an existing composition is durable session storage plus both Team packages:
 
 ```yaml
-- id: agent-team
-  name: '@deepseek-ai/dsh-experimental-agent-team'
-  config:
-    maxMembers: 8
-    maxTasks: 256
-    maxPendingMessagesPerMember: 64
-    maxMessageBytes: 65536
-    disposalTimeoutMs: 5000
+# smallest team setup — durable storage plus both Team packages
+- name: '@deepseek-ai/dsh-session-persistence-jsonl'
+- name: '@deepseek-ai/dsh-experimental-agent-team'
+- name: '@deepseek-ai/dsh-experimental-tool-agent-team'
 ```
 
-Every limit must be a positive safe integer. `maxMembers` counts every name ever provisioned, including failed members, because names are never reusable. `maxTasks` counts non-deleted tasks. The mailbox limit is per target; the byte limit covers the complete framed delivery, including its stable id and sender name. `disposalTimeoutMs` bounds admitted creation, mailbox dispatch, and Team-owned Activation settlement so plugin reload and process shutdown fail visibly instead of waiting forever.
+With the tools installed, the model does the rest on request — for example, "create a teammate named reviewer to check the diff", then "send reviewer the change summary". All limits are optional and validated at startup:
 
-The service requires Agent, Session, Session persistence, and continuable-subagent services. A composition without durable Session storage does not activate it.
+| Field | Default | Meaning |
+|---|---|---|
+| `maxMembers` | `8` | Maximum teammates a team may ever create, including failed ones |
+| `maxTasks` | `256` | Maximum active tasks on the board |
+| `maxPendingMessagesPerMember` | `64` | Maximum queued messages for one member |
+| `maxMessageBytes` | `65,536` | Maximum size of one sent message |
+| `disposalTimeoutMs` | `5,000` | Time allowed for shutdown cleanup |
 
-## Team identity and roster
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-experimental-agent-team) is the exhaustive source for every accepted field and its JSDoc.
 
-Every ordinary runtime root is the implicit Lead of a Team whose `TeamId` equals its `SessionId`; creating a Team is therefore state-free until the first member, message, or task record. A teammate is a named, continuable direct child recorded in that root's Session. Names are lowercase kebab-case, at most 64 characters, and immutable for the Team lifetime. Session ids remain the persistence and authorization identities.
+### Teammates
 
-`spawnTeammate()` first appends and flushes a provisioning member, then asks the configured spawn or fork provider to create the reserved child id. A provider failure appends a durable failed member. Successful inbox admission is flushed in the child Session before the active edge commits. On root recovery, a provisioning record becomes active only when the independently persisted child has matching direct-parent and continuable descriptors plus its initial user message, either still pending in the durable inbox or already recorded in history; otherwise it becomes failed. If recovery wins a same-process provisioning race, the creator accepts the matching terminal state or reports `TEAM_PROVISIONING_CONFLICT` and drains a child that recovery already marked failed. Disposal closes admission, aborts and awaits admitted creation and mailbox-dispatch transactions, then asks the continuation owner to release the roster's exact live direct children and their descendants. Non-Team continuable children of the Lead remain untouched. Cleanup failures make disposal fail visibly. This closes crashes and reload races between root provisioning and its terminal member edge without reusing a name or retaining an orphan Activation.
+Ask the Lead to create a teammate: give it a unique lowercase name such as `reviewer` and describe its job. A teammate starts fresh with no memory of the Lead's conversation, or as a fork that inherits the Lead's completed turns; the creation request chooses which. Teammate names are permanent — even a teammate whose creation failed keeps its name, and no name is ever reused.
 
-Fresh children have no parent-history seed. Fork children capture the Lead's completed-turn prefix once; the in-flight delegation turn is excluded. Inherited Team records carry the old root's `TeamId` and are ignored when an ordinary fork becomes an independent runtime root. Provider-owned subagents outside the roster do not become nested Team Leads.
+The roster shows every member with its role (`lead` or `teammate`) and current status: `running`, `idle`, `inactive` (a member that exists but is not loaded), `provisioning`, or `failed`. A member that is not loaded receives its messages when it wakes.
 
-The roster reports durable provisioning/failed phases and live `running`/`idle` status. An active but non-resident teammate is `inactive`; later waking delivery cold-resumes it through the continuation owner.
+Only the Lead can create teammates or interrupt them.
 
-## Durable mailbox
+### Messages between teammates
 
-`sendMessage()` validates peer membership, appends `team/message/queued`, and flushes before attempting delivery. The result always identifies that durable message; `queued` means immediate delivery was deferred and is not an instruction to resend. Quiet delivery injects, flushes, and acknowledges context immediately when the target is live, but never activates an inactive target; an inactive target's quiet message remains queued. Wakeup delivery becomes the target's next FIFO turn and cold-resumes it when needed.
+Any member can send a message to any other member or to the Lead. A live member receives it immediately; an offline member's messages queue and arrive when it resumes. Messages are never lost and never delivered twice.
 
-The target message begins with `Team message <id> from <name>:` and retains the same id and sender in `TeamMessageSource`. Once the target Session durably holds that identity either in its pending inbox or recorded user-message history, the Lead log appends `team/message/delivered`. Immediate admissions are serialized per target in durable queue order, and recovery dispatches queued-minus-delivered records in the same order. Delivery folds both live and persisted inbox/history state before retrying, so a crash between inbox acceptance and model claim does not duplicate the message. A successful Lead-log flush wakes current `waitForChange()` callers, which then re-list authoritative state.
+Two delivery modes cover the two common intents: a quiet message delivers information without starting an idle teammate (use it for updates that can wait), and a follow-up makes the message the recipient's next turn (use it to hand over work). The sender always sees the outcome — delivered now, or queued. A queued message is already safely stored, so it must not be resent.
 
-The guarantee is process-local retry plus target-Session de-duplication, not cross-process exactly-once delivery. This release has no shared mailbox transaction across processes and no mailbox timeline UI.
+### Shared task board
 
-## Shared task board
+Any member can add a task with a title, details, optional dependencies on other tasks, and optional hints about which files it will touch. A task is claimable only when everything it depends on is complete.
 
-Tasks are complete versioned snapshots. Every mutation carries `expectedRevision`; stale callers receive `TEAM_TASK_STALE_REVISION` instead of overwriting a newer value. Any member can create, read, or claim a ready unowned task. The owner or Lead can edit, release, complete, reopen, or delete it; only the Lead can assign another member. Numeric `task-<n>` ids require a safe-integer suffix; creation reports `TEAM_TASK_LIMIT` instead of reusing the final safe id.
+Tasks have an owner: a member claims a task to start work, completes it when done, releases it back, or reopens it; the Lead can assign a task to any member. Every change is compare-and-set: an update based on an outdated copy is rejected, so two members cannot silently overwrite each other's work.
 
-Dependencies must name current non-deleted tasks and form a complete DAG with no self or duplicate edge. A pending task is ready only after every blocker completes. Deleting a task that still has a non-deleted dependent is rejected. Deleted tasks remain tombstones for replay and id stability but do not consume `maxTasks` or appear in `listTasks()`.
+File hints produce warnings when two in-progress tasks plan to touch overlapping paths — they never block anything. Deleted tasks remain in history but disappear from the active list.
 
-`writeScopes` are normalized workspace-relative prefixes. Views warn when they overlap an in-progress task, but they never block claim or authorize filesystem writes. They are coordination hints, not locks.
+### Waiting and interruption
 
-`waitForChange()` waits for one roster, task, mailbox, or live-status edge that occurs after registration, for 10 seconds through one hour; it reports only whether the wait timed out and does not replay a change that already happened. Runtime disposal releases current waits and makes later waits return immediately without a timeout. Callers re-read authoritative state after wakeup or timeout. Cancellation preserves an Error reason or reports a non-Error reason through `TEAM_WAIT_ABORTED` with structural inspection instead of object coercion. `interrupt()` is Lead-only and delegates to the continuable-subagent interrupt path, which cancels only a live teammate's current turn with `keepInbox`; it neither releases task ownership nor deletes durable mail.
+A member can wait for the next team change — a teammate's status, an incoming message, or a task update — instead of polling repeatedly; the wait reports only whether it timed out, and the caller re-reads the current state afterward.
 
-The separate `./invariant` companion replays each candidate Team event against its committed Session prefix. Replay validates every current-version Team payload before it enters folded state, then rejects invalid member transitions, reused names, out-of-range numeric task ids, discontinuous task revisions, invalid task dependencies, duplicate queue/ack records, and acknowledgements with the wrong target before append. Session event `seq` and `time` own ordering and timing instead of duplicated snapshot timestamps.
+The Lead can stop a teammate's current turn without deleting its queued messages; task ownership is unchanged.
 
+### What success and failure look like
+
+Success looks like a teammate appearing in the roster, a message reporting `accepted` or `queued`, and task revisions advancing with each change. Likely failures are reported as specific errors instead of silently corrupting state: sending to a name that is not a member, claiming a task that is not ready, editing with an outdated revision, or creating a teammate beyond the member limit.

+## Understand the implementation

+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the service and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The service is built on one separation and three commitments:
+
+- **Durable log, derived state.** The Lead Session log is the single source of truth; roster, mailbox, and task state are replayed from it on every read.
+- **Process-local ownership.** All coordination lives in one process; the guarantee is retry plus de-duplication, never cross-process consensus.
+- **Explicit authority.** Every service method takes the exact live calling `Agent`; only the Lead spawns, reassigns, or interrupts.
+- **Bounds that fail loud.** Every limit is a validated deployment value, and exhaustion reports a typed error instead of reusing an id or name.
+
+The [Agent Teams Agent Note](../../../.agents/notes/implemented/feature/2026-08-05-agent-teams.md) owns the identity, mailbox, task, and shared-checkout decisions.
+
+### Source map

+
+### Team identity and roster
+
+Every ordinary runtime root is the implicit Lead of a Team whose `TeamId` equals its `SessionId`; there is no creation event, and durable state begins with the first member, message, or task record. `spawnTeammate()` first appends and flushes a `provisioning` member record, then asks the configured provider to create the reserved child; a provider failure appends a durable `failed` member. A fresh child starts with no Lead history; a fork child captures the Lead's completed-turn prefix once. Recovery reconciles an unterminated provisioning record against the child's independently persisted Session: a matching direct-parent and continuable descriptor plus a recorded initial user message produces `active`, and anything else produces `failed`. If recovery wins a same-process race, the creator accepts the terminal state or reports `TEAM_PROVISIONING_CONFLICT` and drains the child. Names are reserved by the first provisioning record and never reused.
+
+### Durable mailbox
+
+`sendMessage()` validates peer membership, appends `team/message/queued`, and flushes before attempting delivery. The target message begins with `Team message <id> from <name>:` and keeps the same id and sender in `TeamMessageSource`. A target receipt is acknowledged with `team/message/delivered` only after the target Session durably holds the message identity in its pending inbox or recorded history. Immediate admissions are serialized per target in durable queue order; recovery dispatches queued-minus-delivered records in the same order. Delivery folds both live and persisted target inbox/history state before retrying, so a crash between inbox acceptance and model claim does not duplicate the message. The guarantee is process-local retry plus target-Session de-duplication, not cross-process exactly-once delivery.
+
+### Shared task board
+
+Tasks are complete versioned snapshots; every mutation carries `expectedRevision`, and a stale caller receives `TEAM_TASK_STALE_REVISION` instead of overwriting a newer value. Numeric `task-<n>` ids require a safe-integer suffix, and id-space exhaustion reports `TEAM_TASK_LIMIT` instead of reusing the final id. Deleted tasks remain tombstones for replay and id stability but do not consume `maxTasks` or appear in `listTasks()`. `writeScopes` are normalized workspace-relative prefixes; views warn on overlap with in-progress tasks but never block claim or authorize writes.
+
+### Waiting and interruption
+
+`waitForChange()` waits for one roster, task, mailbox, or live-status edge that occurs after registration, from ten seconds through one hour, and reports only whether it timed out; runtime disposal releases current waits. Cancellation preserves an Error reason or reports a non-Error reason through `TEAM_WAIT_ABORTED`. `interrupt()` is Lead-only and delegates to the continuable-subagent interrupt path, which cancels only a live teammate's current turn with `keepInbox`; it neither releases task ownership nor deletes durable mail.
+
+### Durability model
+
+Team events are appended to the exact live Lead Session and flushed before the operation reports success or wakes waiters. `team/member`, `team/task`, `team/message/queued`, and `team/message/delivered` are log-only: they never enter the conversation surface, so derived model history is untouched by coordination records. Session event `seq` and `time` own ordering and timing; snapshots do not duplicate them. The `./invariant` companion replays each candidate Team event against its committed prefix and rejects invalid transitions before append.
+
+### Disposal
+
+Disposal closes admission, aborts and awaits admitted creation and mailbox-dispatch transactions, then asks the continuation owner to release the roster's exact live direct children and their descendants; non-Team continuable children of the Lead remain untouched. Cleanup failures make disposal fail visibly, bounded by `disposalTimeoutMs`.

 ## Known Limitations and Deferred Work
 
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits describe what a team cannot do yet or what needs special operational care. They are current package constraints, not a comparison with other coordination mechanisms.
+
+- **Experimental prototype with no stability promise** — the package is private, excluded from official releases, and its contracts change freely while it incubates.
 - **One process and one shared checkout** — members share cwd and observe edits immediately; this package provides no worktree, remote member, merge, or filesystem lock.
 - **Advisory write scopes** — Bash, formatters, code generators, and direct external writers can bypass filesystem version checks; Leads must coordinate ownership and review the final diff.
 - **Flat immutable roster** — only the Lead creates direct teammates; there is no nested Team, rename, deletion, or name reuse.
 - **No automatic ownership release** — idle, interruption, process exit, and failed work do not release a task owner.
 - **Mailbox is not cross-process exactly-once** — concurrent harness processes over one Team are unsupported.

-隐式 Root Agent Teams 领域。`ctx.agentTeams` 在 Lead Session 日志中维护扁平的 Lead／teammate roster、持久 peer mailbox 与共享任务 DAG。[Agent Teams Agent Note](../../../.agents/notes/implemented/feature/2026-08-05-agent-teams.zh.md)负责协作和隔离决策；[Team 子系统目录](../../../docs/subsystems/agent-team.zh.md)记录持久数据的字面形态与服务 API。
+## 概述
 
-## 配置
+`dsh-experimental-agent-team` 把一个编码会话变成一个小型工作团队：会话中的 agent 成为 Lead，创建具名 teammate 处理委派的工作，与它们交换持久消息，并在公共任务板上跟踪共享任务。消息与任务状态能挺过崩溃、reload 与中断，因此离线的 teammate 会在恢复后收到排队的消息。它本身不提供任何工具——请挂载兄弟包 `dsh-experimental-tool-agent-team`，让模型能够创建 teammate、给它们发消息并使用任务板。它是实验性的：不进入正式发布、不承诺稳定性，并且需要持久会话存储才能激活。

+## 使用本包
+
+当一个 agent 应该在自己的工作目录中运行一支小型具名助手团队、且消息与任务状态需要挺过崩溃与重启时，把本包加入组合。它本身不带工具：请与 `@deepseek-ai/dsh-experimental-tool-agent-team` 一起挂载，让模型能够创建 teammate、给它们发消息并使用任务板。
+
+### 何时选择
+
+当多个 agent 必须在同一个共享工作区协作、且 roster、消息与任务状态需要挺过崩溃与重启时，选择它。当 teammate 需要独立工作目录、多个进程需要协调同一支团队、或任务 owner 需要自动释放时，请不要选择——这些都不受支持。团队功能需要持久会话存储才能激活。
+
+### 最小工作配置
+
+<a id="smallest-working-setup"></a>
+
+对现有组合的最小增量是持久会话存储加两个 Team 包：
 
 ```yaml
-- id: agent-team
-  name: '@deepseek-ai/dsh-experimental-agent-team'
-  config:
-    maxMembers: 8
-    maxTasks: 256
-    maxPendingMessagesPerMember: 64
-    maxMessageBytes: 65536
-    disposalTimeoutMs: 5000
+# smallest team setup — durable storage plus both Team packages
+- name: '@deepseek-ai/dsh-session-persistence-jsonl'
+- name: '@deepseek-ai/dsh-experimental-agent-team'
+- name: '@deepseek-ai/dsh-experimental-tool-agent-team'
 ```
 
-每个限制都必须是正的安全整数。`maxMembers` 统计所有曾 provision 的名字，包括失败成员，因为名字永不复用。`maxTasks` 统计未删除任务。mailbox 限额按目标成员计算；字节限制覆盖完整的投递帧，包括稳定 id 与发送者名称。`disposalTimeoutMs` 限制已获准创建、mailbox dispatch 与 Team 自有 Activation 的 settlement 时长，使插件 reload 与进程 shutdown 在异常时明确失败，而不是无限等待。
+工具安装后，模型会按请求完成其余工作——例如先「创建一个名为 reviewer 的 teammate 检查 diff」，再「把变更摘要发给 reviewer」。所有限制都是可选的，并在启动时校验：
 
-该服务要求 Agent、Session、Session persistence 与 continuable-subagent 服务。没有持久 Session 存储的组合不会激活它。
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `maxMembers` | `8` | 一支团队最多可创建的 teammate 数，包括失败的 |
+| `maxTasks` | `256` | 任务板上最多的活动任务数 |
+| `maxPendingMessagesPerMember` | `64` | 单个成员最多可排队的消息数 |
+| `maxMessageBytes` | `65,536` | 单条发送消息的最大尺寸 |
+| `disposalTimeoutMs` | `5,000` | 关闭清理允许的时间 |
 
-## Team 身份与 roster
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-experimental-agent-team)是每个受支持字段及其 JSDoc 的穷尽式真源。
 
-每个普通运行时 Root 都是一个隐式 Team 的 Lead，其 `TeamId` 等于 `SessionId`；因此，在写入第一条成员、消息或任务记录前，创建 Team 不需要额外状态。teammate 是记录在 Root Session 中的具名 continuable 直接 child。名字采用小写 kebab-case，最长 64 个字符，在 Team 生命周期内不可变。Session id 始终是持久化与授权身份。
+### Teammate
 
-`spawnTeammate()` 先追加并 flush provisioning member，再要求配置的 spawn 或 fork provider 使用预留 child id 创建成员。provider 失败会追加持久 failed member。初始 inbox 消息获准后，先 flush child Session，再提交 active 边。Root 恢复时，只有独立持久 child 的直接 parent 与 continuable descriptor 匹配，并且其初始用户消息仍在持久 inbox 中或已经记录进历史，provisioning 才转为 active；否则转为 failed。如果 recovery 在同进程 provisioning 竞争中先完成，creator 会接受匹配终态，或报告 `TEAM_PROVISIONING_CONFLICT` 并 drain 已被 recovery 标为 failed 的 child。dispose 会关闭准入，中止并等待已获准的创建与 mailbox dispatch 事务，再让 continuation owner 释放 roster 中确切的 live direct child 及其后代；Lead 的非 Team continuable child 不受影响。cleanup 失败会让 dispose 明确失败。该对账覆盖 Root provisioning 与终态成员边之间的崩溃和 reload 窗口，同时不复用名字或遗留孤儿 Activation。
+请 Lead 创建 teammate：给它一个唯一的小写名字（例如 `reviewer`）并描述其职责。teammate 可以 fresh 启动（不携带 Lead 对话的任何记忆），也可以作为 fork 启动（继承 Lead 已完成的轮次）；创建请求决定用哪种。teammate 名字是永久的——即使创建失败的 teammate 也保留其名字，任何名字都不会被复用。
 
-fresh child 不带 parent 历史 seed。fork child 只捕获一次 Lead 的已完成 turn 前缀，不包含正在执行 delegation 的 turn。继承的 Team 记录带有旧 Root 的 `TeamId`，普通 fork 成为独立运行时 Root 后会忽略这些记录。roster 之外、由 provider 管理的 subagent 不会被误认为嵌套 Team Lead。
+roster 显示每个成员的职责（`lead` 或 `teammate`）与当前状态：`running`、`idle`、`inactive`（存在但未加载的成员）、`provisioning` 或 `failed`。未加载的成员会在唤醒后收到其消息。
 
-roster 同时报告持久 provisioning／failed phase 与实时 `running`／`idle` 状态。active 但不驻留的 teammate 显示为 `inactive`；后续 wakeup 投递会经 continuation owner 冷恢复它。
+只有 Lead 可以创建 teammate 或中断它们。
 
-## 持久 mailbox
+### teammate 之间的消息
 
-`sendMessage()` 校验 peer 成员关系，追加 `team/message/queued` 并 flush，之后才尝试投递。结果始终标识该持久消息；`queued` 表示即时投递被推迟，并不表示需要重发。target 为 live 时，quiet 投递会立即注入、flush 并确认上下文，但绝不会激活 inactive target；inactive target 的 quiet 消息会保持 queued。wakeup 投递成为 target 的下一个 FIFO turn，并在需要时冷恢复它。
+任何成员都可以向任何其他成员或 Lead 发送消息。live 成员会立即收到；离线成员的消息会排队，并在其恢复后到达。消息不会丢失，也绝不会重复投递。
 
-目标消息以 `Team message <id> from <name>:` 开头，并在 `TeamMessageSource` 中保留同一 id 与发送者。target Session 在 pending inbox 或已记录的用户消息历史中持久保存该身份后，Lead 日志才追加 `team/message/delivered`。即时准入按 target 和持久 queue 顺序串行化，恢复也按同一顺序重新投递 queued-minus-delivered 记录。重试前会同时折叠 live 与持久 target 的 inbox／历史状态，因此 inbox 已接受但模型尚未 claim 时发生崩溃也不会复制消息。Lead 日志 flush 成功后会唤醒当前 `waitForChange()` 调用方，调用方随后重新列出权威状态。
+两种投递模式覆盖两种常见意图：quiet 消息在不让 idle teammate 启动的情况下传达信息（用于可以等待的更新），follow-up 让消息成为接收方的下一个轮次（用于移交工作）。发送方始终能看到结果——已送达，或正在排队。排队的消息已经安全存储，因此绝不能重发。
 
-该保证是进程内重试加 target Session 去重，而不是跨进程 exactly-once。本版本没有跨进程共享 mailbox 事务，也没有 mailbox 时间线 UI。
+### 共享任务板
 
-## 共享任务板
+任何成员都可以添加任务，包含标题、详情、对其他任务的可选依赖，以及可选的文件触及提示。只有其全部依赖完成后，任务才可 claim。
 
-任务是完整的版本化快照。每次变更都携带 `expectedRevision`；陈旧调用方会收到 `TEAM_TASK_STALE_REVISION`，不会覆盖更新值。任意成员都可以创建、读取或 claim ready 且无 owner 的任务。Owner 或 Lead 可以编辑、释放、完成、重开或删除任务；只有 Lead 可以分配给其他成员。数字 `task-<n>` id 的后缀必须是安全整数；最后一个安全 id 已被占用时，创建会报告 `TEAM_TASK_LIMIT`，而不会复用该 id。
+任务有 owner：成员 claim 任务开始工作，完成后标记完成、释放回板或重新打开；Lead 可以把任务分配给任意成员。每次变更都是 compare-and-set：基于过期副本的更新会被拒绝，因此两个成员不会悄悄覆盖彼此的成果。
 
-依赖必须指向当前未删除任务，并组成完整 DAG，不允许 self edge 或重复 edge。只有所有 blocker 都 completed，pending 任务才 ready。仍被未删除任务依赖的任务不能删除。删除任务作为 tombstone 保留以供回放和维持 id 稳定，但不占用 `maxTasks`，也不出现在 `listTasks()` 中。
+当两个 in-progress 任务计划触及重叠路径时，文件提示会产生警告——它们绝不阻止任何操作。已删除任务保留在历史中，但从活动列表中消失。
 
-`writeScopes` 会规范化为 workspace-relative 路径前缀。view 会对与 in-progress 任务的重叠发出警告，但绝不会阻止 claim 或授予文件写权限。它们是协作提示，不是锁。
+### 等待与中断
 
-`waitForChange()` 可以等待注册后发生的下一条 roster、task、mailbox 或实时 status 边，时长范围为 10 秒到 1 小时；它只报告等待是否超时，也不会回放调用前已经发生的变化。运行时 dispose 会释放当前等待，并使后续等待不经超时立即返回。调用方需要在唤醒或超时后重新读取权威状态。取消会保留 Error reason；非 Error reason 则通过 `TEAM_WAIT_ABORTED` 以结构化检查结果报告，不再强制转成 object 字符串。`interrupt()` 仅限 Lead，并委托 continuable-subagent 的 interrupt 路径以 `keepInbox` 只取消 live teammate 的当前 turn；它既不释放任务 owner，也不删除持久 mail。
+成员可以等待下一次团队变化——teammate 的状态、新消息或任务更新——而不必反复轮询；等待只报告是否超时，调用方随后重新读取当前状态。
 
-独立的 `./invariant` 配套模块会把每条候选 Team event 对照已提交 Session 前缀回放。回放会先验证每个当前版本 Team payload，再将其纳入折叠状态；随后会在 append 前拒绝非法 member 转换、名字复用、超出范围的数字 task id、不连续任务 revision、非法任务依赖、重复 queue／ack，以及 target 不匹配的 acknowledgement。顺序与时间由 Session event 的 `seq` 和 `time` 负责，不在 snapshot 中重复保存。
+Lead 可以停止 teammate 的当前轮次，而不会删除其排队的消息；任务归属不变。
 
+### 成功与失败的表现
+
+成功的表现是：teammate 出现在 roster 中、消息报告 `accepted` 或 `queued`、任务 revision 随每次变更递增。可能的失败会以具体错误报告，而不会悄悄破坏状态：发给不存在的成员名字、claim 尚未就绪的任务、用过期 revision 编辑、或超出成员上限创建 teammate。

+
+本节解释服务背后的设计决策并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+本服务建立在一个分离与三项承诺之上：
+
+- **持久日志，派生状态。** Lead Session 日志是唯一真源；roster、mailbox 与任务状态每次读取都从中回放。
+- **进程内归属。** 所有协作都位于单一进程；保证是重试加去重，绝不是跨进程共识。
+- **显式权限。** 每个服务方法都接收精确的 live 调用 `Agent`；只有 Lead 可以 spawn、reassign 或 interrupt。
+- **边界大声失败。** 每个限制都是经过校验的部署值，耗尽时报告类型化错误，而不是复用 id 或名字。

+### Team 身份与 roster
+
+每个普通运行时 root 都是一个隐式 Team 的 Lead，其 `TeamId` 等于 `SessionId`；不存在创建事件，持久状态从第一条成员、消息或任务记录开始。`spawnTeammate()` 先追加并 flush 一条 `provisioning` 成员记录，再要求配置的 provider 创建预留 child；provider 失败会追加一条持久的 `failed` 成员。fresh child 不携带 Lead 历史；fork child 只捕获一次 Lead 的已完成 turn 前缀。恢复把未终结的 provisioning 记录对照 child 独立持久化的 Session 进行对账：直接 parent 与 continuable descriptor 匹配、且初始用户消息已记录则产生 `active`，其他任何情况都产生 `failed`。如果恢复在同进程竞争中先完成，creator 会接受终态，或报告 `TEAM_PROVISIONING_CONFLICT` 并 drain 该 child。名字由第一条 provisioning 记录保留，且永不复用。
+
+### 持久 mailbox
+
+`sendMessage()` 校验 peer 成员关系，追加 `team/message/queued` 并在尝试投递前 flush。目标消息以 `Team message <id> from <name>:` 开头，并在 `TeamMessageSource` 中保留同一 id 与发送者。只有目标 Session 在 pending inbox 或已记录历史中持久持有消息身份后，才会以 `team/message/delivered` 确认投递。即时准入按目标与持久队列顺序串行化；恢复按同一顺序重新投递 queued-minus-delivered 记录。重试前会同时折叠 live 与持久目标 inbox／历史状态，因此 inbox 已接受但模型尚未 claim 时发生崩溃不会复制消息。该保证是进程内重试加 target Session 去重，而不是跨进程 exactly-once 投递。
+
+### 共享任务板
+
+任务是完整版本化快照；每次变更都携带 `expectedRevision`，陈旧调用方会收到 `TEAM_TASK_STALE_REVISION`，而不会覆盖更新的值。数字 `task-<n>` id 的后缀必须是安全整数，id 空间耗尽时报告 `TEAM_TASK_LIMIT`，而不是复用最后一个 id。已删除任务作为 tombstone 保留以供回放与维持 id 稳定，但不占用 `maxTasks`，也不出现在 `listTasks()` 中。`writeScopes` 是规范化后的 workspace 相对前缀；视图会对与 in-progress 任务的重叠发出警告，但绝不阻止 claim 或授予写权限。
+
+### 等待与中断
+
+`waitForChange()` 等待注册之后发生的下一条 roster、task、mailbox 或实时状态边，时长从 10 秒到 1 小时，并且只报告是否超时；运行时 dispose 会释放当前等待。取消会保留 Error reason；非 Error reason 则通过 `TEAM_WAIT_ABORTED` 报告。`interrupt()` 仅限 Lead，委托 continuable-subagent 的 interrupt 路径，以 `keepInbox` 只取消 live teammate 的当前 turn；它既不释放任务 owner，也不删除持久 mail。
+
+### 持久性模型
+
+Team 事件追加到精确的 live Lead Session，并在操作报告成功或唤醒等待者之前 flush。`team/member`、`team/task`、`team/message/queued` 与 `team/message/delivered` 仅存在于日志：它们从不进入会话表面，因此派生模型历史不受协作记录影响。顺序与时间由 Session event 的 `seq` 与 `time` 负责，快照不重复保存。`./invariant` 伴生插件把每条候选 Team event 对照已提交前缀回放，并在 append 前拒绝非法转换。
+
+### Dispose
+
+dispose 会关闭准入、中止并等待已获准的创建与 mailbox dispatch 事务，再让 continuation owner 释放 roster 中确切的 live direct child 及其后代；Lead 的非 Team continuable child 不受影响。cleanup 失败会让 dispose 明确失败，并以 `disposalTimeoutMs` 为上限。

-Scoped model-facing adapter for [`ctx.agentTeams`](../agent-team/README.md). It installs the Agent Teams policy and collaboration tools in each implicit Lead and durable teammate scope. Scoped Team definitions shadow same-named legacy global continuable-subagent controls, so a composition that mounts both must disable the legacy definitions.
+## Summary
 
-## Config
+`dsh-experimental-tool-agent-team` gives the model a team toolset on top of the team domain package: create named teammates, send them messages or follow-up work, see who is available, wait for progress, interrupt a stuck teammate, and manage a shared task board — ten tools in total. A short policy section in every member's prompt teaches the model when to form a team (only when you ask for one) and how to coordinate on a shared workspace. Mounting it replaces legacy subagent controls with the same tool names, so a composition that wants both must disable the legacy definitions. It is experimental: excluded from official releases, carries no stability promise, and creates teammates only when you explicitly ask for a team.

+## Use this package
+
+Add this package on top of `@deepseek-ai/dsh-experimental-agent-team` when the model should run a team through tools. Once mounted, every team member — the Lead and each teammate — gets the same ten tools plus a policy paragraph that states its own role and name.
+
+### When to choose it
+
+Choose it when the model should create and coordinate teammates by itself rather than a human driving subagent controls. Avoid it when the legacy global subagent tools with the same names must stay available: the team tools replace them for team members, so a composition that wants both must disable the legacy definitions. The fixed policy creates teammates only when you explicitly ask for a team or teammates, so ordinary tasks never trigger delegation on their own.
+
+### Smallest working example
+
+The smallest addition to an existing composition is the two-package fragment from the [agent-team README](../agent-team/README.md#smallest-working-setup): durable session storage, the team domain package, and this package. The plugin itself takes two optional settings:

The adapter supplies teammate creation; quiet and waking peer delivery; roster listing, waiting, and Lead-only interruption; and task create/list/get/compare-and-set update operations.
+Try it by asking the Lead model: "create a teammate named reviewer to check the diff, then send reviewer the change summary". The model calls the creation tool and then the messaging tool.
 
-Every tool requires the exact calling `Agent`. `spawn_teammate` and `interrupt_agent` enforce Lead authority inside `ctx.agentTeams`, not only in their descriptions. All members can communicate with any peer and use the task board. Task mutations retain the domain's owner/Lead and revision checks.
+### What the model can do
 
-`send_message` succeeds once mail is durable and never wakes an inactive target. `followup_task` also makes the message the target's next turn and can cold-resume it. A `queued` result is accepted durable work and must not be retried. Task readiness does not start an owner. Before arming its 10,000-through-3,600,000-millisecond edge wait, `wait_agent` checks for another member that is running or provisioning; without one it returns `noProgress` immediately with instructions to re-list and use `followup_task`. Otherwise it waits for one post-call Team edge, defaulting to 30,000 milliseconds, and callers re-list after wakeup or timeout because earlier changes are not replayed.
+The ten tools group into four capabilities:
 
-The plugin listens to Agent publication and installs its registrations through that Agent's scope. Fresh creation and cold resume therefore receive the same tool/prompt set before the first model request. Agent disposal and plugin HMR remove every scoped registration; reloading the plugin installs one fresh set in each still-live member without changing its continuation Activation.
+- **Create a teammate** — `spawn_teammate` takes a name, a description, and the initial task; only the Lead can call it.
+- **Send messages** — `send_message` delivers information without waking an idle teammate; `followup_task` makes the message the recipient's next turn and wakes it when needed.
+- **See and wait** — `list_agents` shows the roster with live status; `wait_agent` waits for the next team change; `interrupt_agent` stops a teammate's current turn (Lead only).
+- **Manage the task board** — `team_task_create`, `team_task_list`, `team_task_get`, and `team_task_update` add, browse, read, and update shared tasks.
 
+Any member can message any other member and use the task board; only the Lead creates and interrupts teammates. Task updates keep the domain's owner and revision checks, so an outdated edit is rejected instead of overwriting newer work.
+
+### What success and failure look like
+
+Sending a message succeeds as soon as it is safely stored: the result is `accepted` (delivered now) or `queued` (waiting), and a queued message must not be resent. `wait_agent` returns `noProgress` right away when no other member is running or provisioning, telling the caller to wake a teammate first; otherwise it waits for the next change and the caller re-reads state afterward. Task edits based on an outdated revision are rejected rather than overwriting newer work.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the adapter and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The adapter is built on three commitments:
+
+- **Scoped, not global.** Every registration lives on the member Agent's own `ctx`; nothing is installed for non-Team subagents or the host.
+- **Declared results, compact JSON.** Every tool declares its complete result schema and renders that value as compact JSON, so the compiler checks `execute` against what the model is promised and no result spends tokens on indentation.
+- **The domain owns authority.** Tools delegate to `ctx.agentTeams`, which enforces Lead authority and revision checks; the adapter adds no weaker path.
+
+The [Agent Teams Agent Note](../../../.agents/notes/implemented/feature/2026-08-05-agent-teams.md) owns the model-facing and scoping decisions.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: config, the fixed policy text, and the ten scoped tool registrations |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; delegation is observable only through `ctx.agentTeams`) |
+
+### Policy and tools
+
+One `team:policy` section on the member scope teaches each member its role and the coordination rules; the fixed text and the ten tool registrations are declared in [`src/index.ts`](src/index.ts). The ten tool schemas appear only in Team member scopes, so non-Team subagents keep the default catalog. Scoped registrations with the same names as the legacy global continuable-subagent controls shadow those globals for team members only.
+
+### Scoped registration and teardown
+
+`maybeInstall` runs for every live Agent and subscribes to `agent/created`; it skips Agents without Team membership. Disposal of an Agent runs the installed disposer, and plugin HMR disposes every installed scope before reinstall. Each disposer unwinds registrations in reverse order, so a failed install cannot leave a partial scope.

-[`ctx.agentTeams`](../agent-team/README.zh.md) 的 scoped 模型适配器。它会在每个隐式 Lead 与持久 teammate scope 中安装 Agent Teams 策略和协作工具。scoped Team 定义会覆盖同名的旧全局 continuable-subagent control，因此同时挂载两者的组合必须禁用旧定义。
+## 概述
 
-## 配置
+`dsh-experimental-tool-agent-team` 在团队领域包之上给模型一套团队工具：创建具名 teammate、给它们发消息或后续任务、查看谁在线、等待进展、中断卡住的 teammate，以及管理共享任务板——共十个工具。每个成员的提示词中都有一段简短策略，教模型何时组建团队（只有你要求时）以及如何在共享工作区协作。挂载它会用同名的团队工具取代旧版 subagent 控件，因此想同时使用两者的组合必须禁用旧定义。它是实验性的：不进入正式发布、不承诺稳定性，并且只有你明确要求组建团队时才会创建 teammate。

+## 使用本包
+
+当模型应该通过工具运行一支团队时，在 `@deepseek-ai/dsh-experimental-agent-team` 之上挂载本包。挂载后，每个团队成员——Lead 与每个 teammate——都会获得相同的十个工具，外加一段说明自身角色与名字的策略段落。
+
+### 何时选择
+
+当模型应该自行创建与协调 teammate、而不是由人来操作 subagent 控件时，选择它。当同名的旧全局 subagent 工具必须继续可用时，请不要选择：团队工具会为团队成员取代它们，因此想同时使用两者的组合必须禁用旧定义。固定策略只在明确要求团队或 teammate 时创建成员，因此普通任务永远不会自行触发委派。
+
+### 最小工作示例
+
+对现有组合的最小增量是 [agent-team README](../agent-team/README.zh.md#smallest-working-setup) 中的两包片段：持久会话存储、团队领域包与本包。插件本身只有两个可选设置：

-## 工具与权限
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-experimental-tool-agent-team)是每个受支持字段及其 JSDoc 的穷尽式真源。
 
-生成的[工具目录](../../../docs/tool-catalog.zh.md#deepseek-aidsh-experimental-tool-agent-team)负责精确 schema。该适配器提供 teammate 创建；quiet 与 waking peer 投递；roster 列表、等待和仅限 Lead 的 interrupt；以及任务 create／list／get／CAS update 操作。
+试试这样要求 Lead 模型：「创建一个名为 reviewer 的 teammate 检查 diff，再把变更摘要发给 reviewer」。模型会调用创建工具，然后调用消息工具。
 
-每个工具都要求完全相同的调用 `Agent`。`spawn_teammate` 与 `interrupt_agent` 在 `ctx.agentTeams` 内部强制执行 Lead 权限，而不只依赖描述。所有成员都可以与任意 peer 通讯并使用任务板。任务变更保留领域层的 Owner／Lead 与 revision 校验。
+### 模型能做什么
 
-`send_message` 在 mail 持久化后即成功，并且绝不会唤醒 inactive target。`followup_task` 还会让该消息成为 target 的下一个 turn，并可冷恢复 target。`queued` 结果表示持久工作已经接受，不能重试。任务 ready 不会启动 owner。`wait_agent` 在注册 10,000 到 3,600,000 毫秒的边等待前，会检查是否有另一个 running 或 provisioning member；如果没有，它会立即返回 `noProgress`，提示重新 list 并使用 `followup_task`。否则它会等待调用后发生的一条 Team 边，默认 30,000 毫秒；由于不会回放更早的变化，调用方需要在唤醒或超时后重新 list。
+十个工具分为四类能力：
 
-插件监听 Agent publication，并通过对应 Agent scope 安装注册。因此，fresh 创建与 cold resume 都会在第一次模型请求前获得相同工具／提示词集合。Agent dispose 和插件 HMR 会移除全部 scoped 注册；重新加载插件会为仍 live 的每个成员安装一套新注册，而不改变 continuation Activation。
+- **创建 teammate**——`spawn_teammate` 接收名字、描述与初始任务；只有 Lead 可以调用它。
+- **发送消息**——`send_message` 在不唤醒 idle teammate 的情况下传达信息；`followup_task` 让消息成为接收方的下一个轮次，并在需要时唤醒它。
+- **查看与等待**——`list_agents` 显示带实时状态的 roster；`wait_agent` 等待下一次团队变化；`interrupt_agent` 停止 teammate 的当前轮次（仅限 Lead）。
+- **管理任务板**——`team_task_create`、`team_task_list`、`team_task_get` 与 `team_task_update` 添加、浏览、读取与更新共享任务。
 
+任何成员都可以给任何其他成员发消息并使用任务板；只有 Lead 可以创建与中断 teammate。任务更新保留领域的 owner 与 revision 校验，因此过期的编辑会被拒绝，而不是覆盖更新的成果。
+
+### 成功与失败的表现
+
+发送消息在安全存储后即成功：结果为 `accepted`（已送达）或 `queued`（等待中），排队的消息绝不能重发。当没有其他成员 running 或 provisioning 时，`wait_agent` 会立即返回 `noProgress`，提示调用方先唤醒 teammate；否则它会等待下一次变化，调用方随后重新读取状态。基于过期 revision 的任务编辑会被拒绝，而不是覆盖更新的成果。

+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释适配器背后的设计决策并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+适配器建立在三项承诺之上：
+
+- **按作用域，而非全局。** 每个注册都位于成员 Agent 自己的 `ctx` 上；非 Team subagent 或宿主不会安装任何内容。
+- **声明式结果，紧凑 JSON。** 每个工具都声明完整结果 schema，并把该值渲染为紧凑 JSON，因此编译器会对照模型被承诺的值检查 `execute`，任何结果都不会在缩进上消耗 token。
+- **领域拥有权限。** 工具委托给 `ctx.agentTeams`，后者强制执行 Lead 权限与 revision 校验；适配器不添加更弱的路径。
+
+[Agent Teams Agent Note](../../../.agents/notes/implemented/feature/2026-08-05-agent-teams.zh.md)负责模型侧与 scoping 决策。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：配置、固定策略文本与十个 scoped 工具注册 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；委托只能通过 `ctx.agentTeams` 观察） |
+
+### 策略与工具
+
+member scope 上的一个 `team:policy` 段落教每个成员自己的角色与协作规则；固定文本与十个工具注册都声明在 [`src/index.ts`](src/index.ts)。十个工具 schema 只出现在 Team member scope 中，因此非 Team subagent 保持默认目录。与旧全局 continuable-subagent 控件同名的 scoped 注册只会为团队成员覆盖这些全局控件。
+
+### 按作用域注册与拆除
+
+`maybeInstall` 对每个 live Agent 运行，并订阅 `agent/created`；它跳过没有 Team 成员关系的 Agent。Agent dispose 会运行已安装的 disposer，插件 HMR 会在重新安装前处置每个已安装的 scope。每个 disposer 按逆序展开注册，因此失败的安装不会留下残缺 scope。

-Model-facing tools over the live cordis runtime the agent itself runs inside: inspect the loaded plugins and service API, define and run model-written dynamic packages, and retract them again — plus the restricted repository Plugin runtime. Both browser-half packages live here rather than under `packages/client/` because they are halves of this subsystem's dual-half packages; the host aggregate excludes them so each face keeps its own compiler program. Design home: [the toolset Agent Note](../../.agents/notes/implemented/feature/2026-07-08-self-referential-cordis-toolset.md).
+## Summary
+
+The extensions group lets a running agent modify the runtime it runs inside: the model can inspect the plugins and services loaded in the current DSH process, define a dynamic Cordis package (with a host half, a browser half, or both), run it, stop it, and remove it, and a browser panel operates every definition. Packages evolve by plugin: a plugin holds immutable package versions and can run or update between them. Definitions live only in process memory, so a DSH restart clears them and nothing here writes repository files or configuration. Four packages form the subsystem: the model-facing tools plus the host runner, and the browser runner plus the browser UI.

 # @deepseek-ai/dsh-cordis-client-runner
 
 English | [中文](README.zh.md)
 
-Browser half of dynamic dual-half plugin packages. The host-side runner holds every definition's code in process memory and asks the open pages, over a `cordis/request-run` event, whether to run one; this package answers that request, turns the definition into a live browser plugin, and turns a `dynamicCordisRunner/retract` event back into a clean page.
+## Summary
 
-## What it does
+`dsh-cordis-client-runner` lets a page run the browser half of a dynamic Cordis package: it answers the host's run requests, loads the browser-half source into the page as a live plugin, and removes it when the host retracts the run. A person approves or declines a run — or starts one directly — and the result this package reports back becomes the `cordis_run` tool result the model reads. Nothing loads at activation and nothing is restored after a refresh; a page runs a dynamic package only when someone answers a run request or asks for it here.
 
-1. **Event subscription** — the four announcements are forwarded host cordis events, so this package consumes `cordis/request-run`, `cordis/request-run-resolved`, and `dynamicCordisRunner/retract` through `ctx.remote.$on`, whose key set IS the api-remotes allowlist.
-2. **Closure evaluation** — the browser half's source runs as an async function body whose parameters are its symbol surface (`React`, `console`, `styles`, `host`, plus teaching traps shadowing `setTimeout`/`fetch`/`require`). No JSX, no TypeScript, no module imports.
-3. **Guard facade** — `apply` receives a whitelisting proxy over the real fiber ctx: lifecycle verbs plus the services the returned plugin declared in its own `inject` (so the object form `{ inject: ['slots'], apply(ctx) {} }` is what reaches a service; a plain function has no declaration site and reaches none). The `slots` seat assigns the shadowing priority (registering IS shadowing, newest run wins); the `theme` seat pins the override layer's source to the package id and hangs its disposer on the fiber.
-4. **Loader entries** — the guarded plugin is seated in the module table and mounted through `loader.create`, so a dynamic package rides the same activation gating, fiber-effect cleanup, and status projection as a static one. Unload is entry removal plus factory invalidation plus style removal.
-5. **Run orchestration** — a `cordis/request-run` event asks this page whether to run a definition. Whoever answers drives the run in order: the host half first, then the source fetch, then the browser half, then one resolution carrying what happened. A user pressing "run" is itself the authorization and orchestrates the same way with nothing to answer — and for a host-only definition the run ends at the host half, because there is no second half to fetch or load here.
-6. **Package-internal RPC** — a package's `host.call` routes to its own host half through the `dynamicCordisRunner` Remote namespace (`invoke`), and each routing failure code becomes its own teaching error. Both directions carry JSON only: an omitted argument travels as `null` (so `host.call('listServices')` is legal and the handler receives `null`), and a payload the generated codec refuses — a function, `undefined`, a class instance — becomes a teaching error naming the call and the contract instead of the codec's bare field name.
-7. **Render-failure reflow** — the slot registry's supervision seam (`slots.onEntryError`) fires for every entry-boundary crash on the page; the ones belonging to a package this runner seated go to two outlets from that one observation: upstream to the authoring session (`reportRenderFailure`, for the model) and onto this package's own `renderFailures` face field (for the panel row). Ownership is keyed on component identity, recorded when the guard's `register` proxy seats it, because the registry stores the component verbatim — so no parallel ledger of entries has to be kept in step. This is post-settle diagnosis only: it carries no settle authority, never touches a run resolution, and a failed report is swallowed rather than turning one crash into two.

-Loads converge by `(id, rev)` against live state: loading a revision this page already runs answers from live state without reloading (so a replayed run does not look unanswered), a newer revision replaces it, and the same revision after a retract loads afresh. Operations serialize per definition.

+Mount this plugin in a web client whose composition also mounts the host runner — the host half runs in the process, this browser half in the page. When a dynamic package that has a browser half is run, the open pages receive a run request; this package carries out the load on this page, and the UI package (`ui-cordis`) renders the panel and cards a person uses to answer it. Host-only packages need no browser half and therefore no page: the host runs them itself.

-- `activeRuns` — each definition's single in-flight activity: `awaiting-approval` (the request id to answer plus the ask's session, package name, and purpose) or `orchestrating` (the session the run is being carried out for). Both arms name the session because grouping belongs to the run, not to its phase; the waiting arm carries the ask's own text because `cordis_define` broadcasts nothing, so a request can name a definition the last registry read does not cover and then this entry is the only source that row has. A surface renders from it and keeps no copy, which is what makes the affordance survive a remount.
-- `renderFailures` — this page's last render crash per definition (slot, teaching message, and whether the crash retired the entry from its cell), on the same notification channel as the live set. Page-local and current by construction: it clears when the package stops, is retracted, or loads again, so a row can render it directly. The host keeps its own last-across-pages copy for the model — the two have different owners and lifetimes, and a surface must not read the host's back in place of this one.
-- `lastRunError` — why this page's own attempt failed, per definition. It outlives the activity, because the host disposes only the half a failed request started: a page can be looking at a definition the host reports as running while having nothing loaded itself.
-- `approve(requestId)` / `decline(requestId)` / `startUserRun({ agentId, id, hasClientHalf })` — the two entries. All three are idempotent (per request id, and per definition for the user's own run), so a double press cannot start two runs. `hasClientHalf` is required: a host-only definition has no source to fetch, so the caller states the shape from the registry row it is acting on rather than the orchestrator learning it from a failed fetch. An answerable request always has a browser half, because the host runs a host-only definition itself instead of asking a page.
-- `subscribe()` / `getSnapshot()` / `isLoaded(id)` — what this page has loaded. `isLoaded` is page-local truth, never the host's "it is running".
+A browser half is written in plain JavaScript — no JSX, no TypeScript, no module imports — and runs as an async function. It receives a fixed set of names — `React`, `console`, `styles`, and `host` — while browser globals like `fetch` and `setTimeout` are unavailable. The plugin it returns can use the lifecycle verbs and only the services it declared in its own `inject`. Calling `host.call(method, args)` from the loaded half reaches its own host half. A crash that happens while React renders the loaded half is reported to the host with the slot, whether the crash removed the entry, and a message written for the author.
 
+### What the run surface offers
+
+A run surface can answer a pending host request — approving it, optionally covering future versions of the same plugin, or declining it — and can start a definition at the user's own gesture, which authorizes it. Each definition has at most one in-flight activity, so an affordance built on that state survives a remount. What the surface shows about this page is page-local: the last render crash per package, why this page's own attempt failed, and whether a package is loaded here — never the host's view of what is running.
+
+### Lifecycle boundaries
+
+Loading is idempotent: asking to load a revision this page already runs changes nothing, a newer revision replaces the loaded one, and the same revision after a retract loads afresh. Operations on a definition serialize. A refresh starts clean by design — the host still holds the definition, this page does not run it until asked again.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design behind the browser half; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The browser half is built on one principle: a dynamic package must ride the same activation gating, fiber-effect cleanup, and status projection as a static one. The evaluated plugin is seated in the module table and mounted through `loader.create`; unload is entry removal plus factory invalidation plus style removal. The guard is a whitelist — lifecycle verbs plus declared services — that mirrors the host-side sandbox facade, so a package author meets one contract on both halves. One observer feeds two outlets: the slot registry's entry-error seam is watched only here, and a crash belonging to a package this runner seated goes upstream to the host for the model and onto this package's own `renderFailures` for the panel.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/client/index.ts`](src/client/index.ts) | Plugin entry: runner, orchestrator, inspect registry, forwarded-event subscription |
+| [`src/client/runtime.ts`](src/client/runtime.ts) | Load engine: convergence by run identity, guarded mount, retract |

+
+### How a run is carried out
+
+A `cordis/request-run` event asks this page whether to run a definition. Whoever answers — the page after an approval, or the user pressing run — drives the orchestration: the host half first (so a host-half failure short-circuits before the browser has moved), then the source fetch, then the browser half, then one resolution carrying what happened. The browser half's source is evaluated as an async function body with the symbol surface as parameters, the returned plugin is guard-wrapped and mounted through the loader, and the resolution reports the loaded revision or the failing stage with the closure's, guard's, or fiber's message. `host.call` routes through the Remote namespace; an omitted argument travels as `null`, and a payload the generated codec refuses becomes a teaching error naming the call and the contract.

The host keeps the last one per package and shows it through `cordis_inspect`; nothing here reaches a run resolution. The same observation also lands on `renderFailures` for the page's own surface — one observer, two outlets, because "the last crash across pages, for the model" and "what this page is showing now" are different facts with different lifetimes.

 ## Known Limitations and Deferred Work
 
-- **A refused resolution is not retried.** The acknowledgement of `resolveRequestRun` is not read, so when the host declines a stale success (`accepted: false`, because the definition's revision moved on while this page was loading) the page keeps what it loaded and does not orchestrate again. The request stays answerable — another page's answer or the caller's cancellation settles it — and the stop that bumped the revision retracts the stale load. Retrying was evaluated and deferred: the window is one revision bump inside a single round trip.
-- The plugin declares `remote.dynamic`, so it stays parked until the host-side namespace exists rather than loading packages whose host half it could never reach.
-- Slot admission (allow/deny lists per deployment) has no carrier: the dispatched row declares services, not target slots.
-- Guard whitelists are hand-mirrored twins of the host-side sandbox facade; sharing one specification is deferred.

-动态双半插件包的浏览器半。host 侧 runner 把每个定义的代码留在进程内存里，并经一条 `cordis/request-run` 事件向打开的页面发问「要不要运行它」；本包回答这个请求、把定义变成活的浏览器插件，并把 `dynamicCordisRunner/retract` 事件变回干净的页面。
+## 概述
 
-## 它做什么
+`dsh-cordis-client-runner` 让页面运行动态 Cordis 包的浏览器半：它应答 host 的运行请求、把浏览器半源码装载进页面成为活插件，并在 host 撤回该次运行时把它移除。人可以批准或拒绝一次运行——也可以直接启动一次——而本包回报的结果变成模型读到的 `cordis_run` 工具结果。激活时什么都不装载，刷新后也不恢复；一页只在有人应答运行请求或在此主动要求时，才运行动态包。
 
-1. **事件订阅** —— 四条公告是转发的 host cordis 事件，所以本包经 `ctx.remote.$on` 消费 `cordis/request-run`、`cordis/request-run-resolved` 与 `dynamicCordisRunner/retract`，而 `$on` 的键面就是 api-remotes 的白名单。
-2. **闭包求值** —— 浏览器半的源码作为一个 async 函数体运行，其参数即符号面（`React`、`console`、`styles`、`host`，外加遮蔽 `setTimeout`/`fetch`/`require` 的教学陷阱）。无 JSX、无 TypeScript、不能 import 模块。
-3. **guard 门面** —— `apply` 收到的是真 fiber ctx 之上的白名单代理：生命周期动词，加上**返回的 plugin 自己在 `inject` 里声明**的服务（所以要用对象形态 `{ inject: ['slots'], apply(ctx) {} }` 才拿得到服务；裸函数没有声明位，拿不到任何服务）。`slots` 座位分配遮蔽 priority（注册即遮蔽，最新一次运行者胜出）；`theme` 座位把覆盖层的 source 钉成包 id，并把它的 disposer 挂到 fiber 上。
-4. **loader entry** —— 加了 guard 的插件被塞进模块表，再经 `loader.create` 挂载，于是动态包与静态包共享同一套激活门控、fiber effect 清理与状态投影。卸载 = 移除 entry + 失效 factory + 撤下样式。
-5. **run 编排** —— 一条 `cordis/request-run` 事件问这一页要不要运行某个定义。回答的那一方按顺序把 run 跑完：先 host 半、再取源码、再浏览器半，最后一次回答带上结果。用户按下「运行」本身就是授权，同样走这条编排，只是没有要回答的对象；而纯 host 定义的 run 到 host 半就结束了 —— 这里没有第二半可取、也没有第二半可装。
-6. **包内 RPC** —— 包内的 `host.call` 经 `dynamicCordisRunner` Remote namespace（`invoke`）转给它自己的 host 半，三种路由失败码各自变成对应的教学错误。两个方向都只驮 JSON：省略入参会以 `null` 过线（所以 `host.call('listServices')` 合法，handler 收到 `null`），而生成的 codec 拒收的载荷（函数、`undefined`、类实例）会变成一条点明「哪次调用 + 约定是什么」的教学错误，而不是 codec 那个光秃秃的字段名。
-7. **渲染期失败回流** —— 槽位注册表的 supervision 接缝（`slots.onEntryError`）对页面上每一次 entry 边界崩溃都会通知；凡属于本 runner 落座过的包，那**一次**观察会分两个出口：一路上行给撰写它的会话（`reportRenderFailure`，给模型看），一路发布到本包 face 上的 `renderFailures`（给面板那一行看）。归属以 component 身份为键，在 guard 的 `register` 代理落座时记下 —— 注册表原样保存 component，所以不需要再维护一份与之同步的 entry 台账。这条通道纯属事后诊断：不驮任何 settle 权威、绝不触碰 run 的最终回答，而且报告本身失败时只吞不抛 —— 不让一次崩溃变成两次。

+## 使用本包
 
-## run 界面读什么、调什么
+在组合里同时挂载了 host runner 的 web 客户端中挂载本插件——host 半跑在进程里，浏览器半跑在页面里。当某个带浏览器半的动态包被运行时，打开的页面会收到一次运行请求；本包在本页执行装载，UI 包（`ui-cordis`）则渲染人用来应答它的面板与卡片。纯 host 包不需要浏览器半，也就不需要页面：host 自己运行它们。
 
-`ctx.dynamicCordisRunner` 就是全部的面:
+### 页面会做什么
 
-- `activeRuns` —— 每个定义唯一的在途活动：`awaiting-approval`（要回答的 requestId，加上这次询问的会话、包名与用途）或 `orchestrating`（这次 run 是为哪个会话在跑）。两条臂都带会话，因为归组属于这次 run 而不属于它的阶段；待确认那条还带着询问自己的文字，因为 `cordis_define` 什么都不播 —— 一个请求可以点名上一次注册表读取没覆盖到的定义，那时这条活动就是那一行唯一的来源。界面从它渲染、自己不留副本 —— 这正是控件能活过 remount 的原因。
-- `renderFailures` —— **本页**最后一次渲染崩溃，按定义索引（槽位、教学 message、以及这次崩溃是否已把 entry 从格位上摘掉），与 live 集合共用同一条通知通道。它按构造就是「本页当前」：包 stop、被 retract、或重新装载成功时即清空，所以界面可以直接照着渲染。host 那边另存一份「跨页面最后一次」给模型 —— 两份的归属与寿命本来就不同，界面**不要**改成回读 host 那份。
-- `lastRunError` —— 本页自己那次尝试为何失败，按定义索引。它比活动活得更久：host 只拆失败请求自己启动的那半，所以一个页面可能看着 host 报告为「在跑」的定义，而自己什么都没装上。
-- `approve(requestId)` / `decline(requestId)` / `startUserRun({ agentId, id, hasClientHalf })` —— 两条入口。三者都幂等（按 requestId，用户自发的 run 按定义 id），所以连点两次不会起两次 run。`hasClientHalf` 是必填：纯 host 定义没有源码可取，所以由调用方从它正在操作的注册表行里把这个事实说出来，而不是让编排器从一次失败的取码里反推。可回答的请求必然带浏览器半 —— 纯 host 定义是 host 自己起的，它不会去问页面。
-- `subscribe()` / `getSnapshot()` / `isLoaded(id)` —— 这一页装了什么。`isLoaded` 是页面本地的事实，永远不等于 host 说的「在跑」。
+浏览器半用纯 JavaScript 编写——无 JSX、无 TypeScript、不能 import 模块——并作为一个 async 函数运行。它拿到一组固定的名字——`React`、`console`、`styles` 与 `host`——而 `fetch`、`setTimeout` 这类浏览器全局不可用。返回的插件只能使用生命周期动词，以及它自己在 `inject` 里声明的服务。从已装载半调用 `host.call(method, args)` 会到达它自己的 host 半。React 渲染已装载半时发生的崩溃会上报 host，点名槽位、崩溃是否已把条目摘掉，以及写给作者的 message。
 
+### 运行界面提供什么
+
+运行界面可以应答一次待审批的 host 请求——批准它（可选地同时覆盖同一插件的未来版本）或拒绝它——也可以按用户自己的手势启动一个定义，该手势本身就是授权。每个定义最多有一个在途活动，因此基于该状态构建的控件能在 remount 后存活。界面就本页显示的内容都是页面本地的：每包最后一次渲染崩溃、本页自己的尝试为何失败，以及某个包是否已在本页装载——绝不是 host 眼中「在跑」的视图。
+
+### 生命周期边界
+
+装载是幂等的：要求装载这一页已在运行的 revision 不会改变任何东西，更新的 revision 顶替已装载的那个，同一 revision 在 retract 之后再装则重新装载。同一定义的操作串行执行。刷新按设计从干净状态开始——host 仍持有定义，本页在再次被要求之前不运行它。

+
+本节解释浏览器半背后的设计；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+浏览器半建立在一个原则之上：动态包必须与静态包共享同一套激活门控、fiber effect 清理与状态投影。求值后的插件被塞进模块表，并经 `loader.create` 挂载；卸载 = 移除 entry + 失效 factory + 撤下样式。guard 是一份白名单——生命周期动词加已声明服务——与 host 侧沙箱门面对称，因此包作者在两侧面对同一个约定。一个观察者供两个出口：只有这里监视槽位注册表的 entry 错误接缝，凡属于本 runner 落座过的包的崩溃，一路上行给 host（给模型），一路发布到本包自己的 `renderFailures`（给面板）。

 # @deepseek-ai/dsh-cordis-host-runner
 
 English | [中文](README.zh.md)
 
-The host half of model-mounted dynamic packages: the definition registry, the `node:vm` sandbox and fiber lifecycle for host halves, the invoke handler table, and the run round trip a browser page carries out. Provided as `ctx.dynamicCordisRunner`. The model-facing tools live in [`@deepseek-ai/dsh-tool-cordis`](../tool-cordis/README.md); the browser half is loaded by [`@deepseek-ai/dsh-cordis-client-runner`](../cordis-client-runner/README.md).
+## Summary
 
-## What it does
+`dsh-cordis-host-runner` makes dynamic packages runnable in this process: definitions the model records with `cordis_define` stay here, host halves run in a `node:vm` sandbox, a package with a browser half waits for a person to approve or decline it on a page, and the model can inspect the live runtime and its definitions here. The model-facing tools live in `@deepseek-ai/dsh-tool-cordis`, and the browser half loads through `@deepseek-ai/dsh-cordis-client-runner`. Definitions live only in process memory, so a DSH restart clears them and nothing is written to disk. One config field, `vmTimeoutMs`, bounds synchronous sandbox evaluation.
 
-Two phases: `define` only records, and everything with an effect hangs off a run.
+## Table of Contents
 
-- `define` / `undefine` own a definition's life. `define` trims and requires the metadata, prechecks each half's syntax by compiling it (running nothing), mints `dyn-<n>`, and records the definition against the session that asked — it has no effect to roll back, so unparseable code is refused before an id exists. `undefine` stops a running definition first, then forgets it. Neither crosses the wire: only the model's own tool call defines.
-- `run` answers the model's request to run one definition, and its two shapes differ by whose business the package is. A host-only package is this process's own: the host half is evaluated in the vm under the `cordis-dynamic` group fiber and the call returns. A package with a browser half has to be carried out by a page, so `run` becomes an answerable round trip — it emits `cordis/request-run`, suspends, and is settled by a person allowing or declining it. There is no timer; the caller's `AbortSignal` (the asking turn was cancelled) is the only other way out, and it announces the cancellation so other pages stop offering an answer. Whether any page will answer is not knowable when the request is sent — a page that received it may still never answer, so a deployment with no page connected suspends like any other unanswered request and ends in `cancelled`. `run` has no wire face — `cordis_run` calls it in process.
-- `runHostHalf` / `getClientCode` are the steps an allowed page walks, host half first, so a host-half failure short-circuits before the browser has moved. `runHostHalf` is idempotent by contract: a running package is bound rather than evaluated again, concurrent calls for one definition evaluate it once, and `startedHere` names the caller that did. `getClientCode` then hands that one page the browser-half source, refusing a definition that is gone, has no browser half, or is not running. Code never rides an announcement, so this is the only way it reaches a browser.
-- `resolveRequestRun` closes the round trip with the answering page's verdict, and broadcasts `cordis/request-run-resolved` so every other page drops the pending affordance. The first answer wins; a later or unknown request id is accepted and ignored. A success naming a revision the registry has moved past is refused rather than applied (`accepted: false`, request still suspended), because the page that answered loaded a dispatch that is no longer live. A failing verdict unwinds the host half only when this same request evaluated it, so a page that cannot load its own half never stops a package the other pages are using.
-- `stop` unwinds one live dispatch — handlers dropped, host-half fiber disposed to quiescence, `dynamicCordisRunner/retract` broadcast — and leaves the definition runnable.
-- `inventory` answers the whole registry, unaddressed by session and with each row naming the session that owns it, because the run-control surface is global. Listing is not acting: every acting verb still checks that ownership. Each row also names whether the definition has a browser half, so a run-control surface offers loading it into the current page only when there is a half to load. `snapshot` is its session-scoped host-local counterpart, carrying each live host half's fiber so `cordis_inspect` can render provides/waiting/state itself (a fiber cannot cross the wire).
-- `reportRenderFailure` records what a page saw a LOADED browser half do wrong at render time. Rendering happens strictly after a load succeeded, so a run has already answered `ok` by then: this report is fire-and-forget, carries no settle authority, and never touches `resolveRequestRun` or any part of the run outcome — **it is not the retired v2 `report`/ack**. The host keeps the last failure per definition across every page (a second page reporting overwrites), and a fresh run, a stop, or an undefine clears it, so the model is never shown a failure from a dispatch that no longer exists. The browser-half face keeps its own "what THIS page is showing now"; the two answer different questions rather than duplicating one. A report for a definition the reporting session does not own is dropped, because the reporting path must never fail a render.
-- `invoke` routes one call from a package's browser half to a method its own host half registered with `harness.handle`. The infrastructure only routes — no host-to-browser direction exists.

-A refusal from `run` or `stop` names one of `definition-missing`, `host-half-failed`, `client-half-failed`, `rejected`, `cancelled`, or `not-running`; the last three are answers rather than defects — a person declined, the asking turn ended, or there was nothing running to stop.
+-----
 
-A definition another session defined reads as absent rather than forbidden, so nothing leaks across sessions. `invoke` and `resolveRequestRun` carry no session at all: a component's call and a page's answer are page-global facts, not one session's.
+<a id="use-this-package"></a>
+## Use this package
 
-Four forwarded events belong to this feature, declared by this package on its client-safe [`./types`](src/types.ts) subpath and allowlisted for delivery by [`@deepseek-ai/dsh-api-remotes`](../../api/remotes/README.md), which is what lets a browser reach them through `ctx.remote.$on`: `cordis/request-run` (`{requestId, agentId, id, name, purpose}` — metadata, never code), `cordis/request-run-resolved` (`{requestId, outcome}`), `dynamicCordisRunner/package` (`{id, name, rev}`), and `dynamicCordisRunner/retract` (`{id, rev}`). The last two are a symmetric pair announcing run state — every fresh start and every stop, whether or not the package has a browser half.
+Mount this plugin in any composition that should support dynamic packages — it powers the model's `cordis_*` tools, and packages with a browser half additionally need the client runner plus the UI package composed on the client side. The common path is explicit: load this package, optionally set `vmTimeoutMs`, and let the tools and the browser do the rest.
 
-## Storage stance
+### Minimal configuration
 
-The registry is process memory and the only source of truth. The session log carries a define call's metadata — never its code — so a restarted process legitimately has no definitions, and a card whose id no longer resolves says exactly that rather than pretending it can run. Nothing here is written to disk, and no definition is restored automatically; a reloaded page holds nothing until someone runs a package again, which is what makes it bind the live host half and re-fetch the browser half.
-
-## Trust stance
-
-The vm sandbox isolates globals but is not a security boundary: Node globals are absent or redirect to Cordis services (`ctx.fs`, `ctx.web`, `ctx.bash`, the timer helpers), and a host half receives a façade without framework internals, yet the services it declares reach the live runtime. Treat a dynamic package like bash access — see the [self-referential toolset Agent Note](../../../.agents/notes/implemented/feature/2026-07-08-self-referential-cordis-toolset.md).
-
-## Config
+```yaml
+- name: '@deepseek-ai/dsh-cordis-host-runner'
+  config:
+    vmTimeoutMs: 5000
+```
 
 | Field | Default | Meaning |
 |---|---|---|
 | `vmTimeoutMs` | `5000` | Milliseconds the synchronous portion of a host half may run in the vm before evaluation is aborted |
 
-One field is all there is: a run request waits for a person, so the round trip has no deadline of its own.
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-cordis-host-runner) is the exhaustive source for every accepted field.
 
-## Export shape
+### What a run does
 
-Service package: default-exports `DynamicCordisRunnerService` (service key `dynamicCordisRunner`), with `./types` carrying the payload shapes the `dynamicCordisRunner` remote namespace and its consumers share. The `define` / `undefine` shapes stay inside the package, because they never cross the wire.
+A definition is recorded by `cordis_define` and activated by `cordis_run`. A package with only a host half activates directly in this process: its code runs in the sandbox. A package with a browser half becomes a request: it waits until a person allows or declines it on a page, or the asking turn is cancelled; the answering page then loads the host half first and the browser half second. `mode: "run"` starts the current package or restarts it, `mode: "update"` switches to a different package version. `cordis_stop` ends the live run — removing the package's handlers and any loaded browser UI — while keeping the definition runnable; `cordis_undefine` stops and forgets it.
 
+### What happens to definitions
+
+Definitions are session-scoped and process-local: a package is visible only to the session that defined it, other sessions read it as absent, and everything disappears on DSH restart. The session log keeps the define call's arguments — including the code it submitted — and the receipt; only the in-memory registry holds the parsed definition. A browser half reaches a page only through a run, so a reloaded page holds nothing until someone runs the package again.
+
+### Trust stance
+
+The sandbox isolates globals but is not a security boundary: Node globals are absent or redirect to Cordis services (`ctx.fs`, `ctx.web`, `ctx.bash`, the timer helpers), and a host half receives a façade without framework internals, yet the services it declares reach the live runtime. Treat a dynamic package like bash access — see the [self-referential toolset Agent Note](../../../.agents/notes/implemented/feature/2026-07-08-self-referential-cordis-toolset.md).

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design behind the runner; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The runner is built on two separations. **Registry and sandbox are one service.** The `DynamicCordisRunnerService` owns the definition registry, the vm sandbox, the host-half fiber lifecycle, and the invoke handler table, so a definition's whole life has one owner. **Versions are immutable packages.** A plugin holds packages that never change after `define`; `currentPackageId` and `nextPackageId` point at the running and target versions, and `mode: "run"` versus `"update"` encodes whether the target equals the current version. The browser round trip exists because a browser half can only be carried out by a page: the service emits a request, suspends, and is settled by the page's verdict, with the caller's `AbortSignal` as the only other exit.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Service entry: `Config`, registry wiring, lifecycle verbs, steer messages |
+| [`src/registry.ts`](src/registry.ts) | Definition store: plugin and package identities, run attempts, approval requests |
+| [`src/sandbox.ts`](src/sandbox.ts) | `node:vm` evaluation: globals, Node-API traps, define-time syntax precheck |
+| [`src/guard.ts`](src/guard.ts) | Registration boundary: schema normalization, the sandbox `ctx` façade, plugin-shape checks |
+| [`src/lifecycle.ts`](src/lifecycle.ts) | Starting a host half under the `cordis-dynamic` fiber group |
+| [`src/inspect-registry.ts`](src/inspect-registry.ts) | The `ctx.cordisInspect` registry: host providers plus the mirrored client manifest |
+| [`src/types.ts`](src/types.ts) | Client-safe payload shapes for the `dynamicCordisRunner` remote namespace and forwarded events |
+
+### How a run flows
+
+`define` trims and requires the metadata, prechecks each half's syntax by compiling it (running nothing), mints the plugin and package ids, and records the definition against the session that asked. `run` resolves the target against `currentPackageId` and `nextPackageId`; a host-only package evaluates in the sandbox and commits immediately, while a browser-half package arms an approval request, emits `cordis/request-run`, and suspends. The answering page walks `runHostHalf`, `getClientCode`, then `resolveRequestRun`; a success naming the live revision commits the activation and sets `currentPackageId`, and `cordis/request-run-resolved` drops the pending affordance on every other page. `stop` retracts the live dispatch — handler disposers, fiber dispose, and the `cordis/dynamic-retract` broadcast — and leaves the definition runnable. Four forwarded events (`cordis/request-run`, `cordis/request-run-resolved`, `cordis/dynamic-package`, `cordis/dynamic-retract`) are declared on the client-safe `./types` subpath and allowlisted for delivery by `@deepseek-ai/dsh-api-remotes`, which is what lets a browser reach them through `ctx.remote.$on`.

 ## Model Experience
 
-### Refusals and teaching errors relayed by the cordis tools
+### Run outcomes, refusals, and diagnostics relayed to the owning session
 
 #### What the model sees
 
-Nothing directly: this package registers no tool and injects no prompt. Its refusals reach the model through the `cordis_*` tool results that call it — an unparseable half names the offending line, a missing definition explains that definitions live in memory only, a `rejected` or `cancelled` run reports that a person declined or the turn ended rather than that anything failed, and a failed browser-half load carries the answering page's own error text.
+Nothing directly: this package registers no tool and injects no prompt. It steers the owning session when a run settles — a success names the current package and says to continue, a user rejection says not to request the same activation again, and a technical failure names the reason, the version pointers, and the inspect-then-correct-and-update path. It also steers post-settle render failures (slot, whether the entry was removed), host guard rejections, and host handler failures. Panel stop and remove gestures inject a user-role message naming what the user did. Refusals from `run` or `stop` also reach the model through the calling tool's result.
 
 #### Token effect
 
-None of its own: every message above is carried by the calling tool's result.
+Conditional and data-dependent: messages arrive only when an event occurs, and each carries a bounded description of what happened; there is no fixed per-request cost.
 
 #### KV Cache effect
 
-A host half that registers tools changes the next request's tool view, which invalidates prefix reuse from the first changed schema token; running or stopping a package with no tool registrations is prefix-neutral.
+None of its own. A host half that registers tools changes the next request's tool view, which invalidates prefix reuse from the first changed schema token; running or stopping a package with no tool registrations is prefix-neutral.
 
 ## Known Limitations and Deferred Work
 
-- **A successful run does not mean the UI rendered.** `run` returns once the answering page has LOADED the browser half; React renders afterwards, so a component that throws cannot possibly appear in the run receipt. The failure surfaces through `reportRenderFailure` and is read back with `cordis_inspect what:"temporary"`; the run result says so rather than implying success.
+<a id="known-limitations-and-deferred-work"></a>
 
-- A package with a browser half **suspends where no page is connected** — headless and ACP deployments hold the run until the asking turn is cancelled, because a forwarded event reports nothing about who received it. Host-only packages are unaffected.
-- A suspended run request has **no timeout**: it waits for a person until the asking turn is cancelled, so unattended automation cannot use packages with a browser half.
-- `vmTimeoutMs` bounds only synchronous evaluation; an async host-half body escapes it, matching the toolset's cooperative trust stance.
-- `runHostHalf` carries no request id, so "which request evaluated this host half" is attributed host-side to the most recently armed request for that definition; several concurrent run requests for one definition would need that rule revisited.
-- A success answer naming a superseded revision is refused (`accepted: false`) and leaves the request suspended, so the model's call ends only through a valid answer or its own cancellation. Settling it would take a fresh orchestration against the live revision, and no page performs that orchestration — the [browser half](../cordis-client-runner/README.md) does not read the ack — so in practice such a request is closed by another page's answer or by the caller's cancellation.
-- A browser half's declared `inject` is read from the plugin it returns in the page, so the announcement carries no service-declaration field at all.
-- **`zod` is a runtime dependency of the generated TypeRT faces, not of `src`.** `./typert` and `./remote` resolve to `lib/typert.*.js`, which `tsc` emits unbundled with a bare `import { z } from 'zod'`, so the package must declare it (the `@deepseek-ai/dsh-goal` precedent) and `knip.json` must ignore it for this workspace — knip reads source, and these faces are build products. Nothing in `src` imports zod.
+
+These limits define when the runner needs special care. They are current package constraints, not a task backlog.

 # @deepseek-ai/dsh-cordis-host-runner
 
 [English](README.md) | 中文
 
-由模型挂载的动态包在 host 侧的那一半：定义注册表、host 半所用的 `node:vm` 沙箱与 fiber 生命周期、invoke handler 表，以及由某个浏览器页面执行的 run 往返。以 `ctx.dynamicCordisRunner` 提供。面向模型的工具在 [`@deepseek-ai/dsh-tool-cordis`](../tool-cordis/README.zh.md) 中；浏览器半由 [`@deepseek-ai/dsh-cordis-client-runner`](../cordis-client-runner/README.zh.md) 装载。
+## 概述
 
-## 功能
+`dsh-cordis-host-runner` 让动态包在本进程中可运行：模型用 `cordis_define` 记录的定义留在这里，host 半在 `node:vm` 沙箱中运行，带浏览器半的包会等待人在页面上批准或拒绝，模型也可以在这里检查实时运行时及其定义。面向模型的工具在 `@deepseek-ai/dsh-tool-cordis` 中，浏览器半经 `@deepseek-ai/dsh-cordis-client-runner` 装载。定义只存在于进程内存中，因此 DSH 重启即清空，也不会向磁盘写任何东西。唯一的配置字段 `vmTimeoutMs` 限制同步沙箱求值的时长。
 
-分两个阶段：`define` 只做登记，一切带副作用的动作都挂在一次 run 上。
+## 目录
 
-- `define`／`undefine` 掌管一个定义的生命周期。`define` 对元数据做首尾去空白与必填校验，通过编译预检每一半的语法（不执行任何代码），铸出 `dyn-<n>`，并把该定义登记在发起调用的会话名下——它没有任何可回滚的副作用，所以无法解析的代码在拿到 id 之前就被拒绝。`undefine` 先停掉正在运行的定义，再把它忘掉。两者都不上 wire：只有模型自己的工具调用才会 define。
-- `run` 回答模型「运行某个定义」的请求，它的两种形态取决于这个包是谁的事。只有 host 半的包是本进程自己的事：host 半在 `cordis-dynamic` group fiber 之下于 vm 中求值，调用随即返回。带浏览器半的包必须由一个页面来执行，于是 `run` 变成一次可作答的往返——它 emit `cordis/request-run`、挂起，并由某个人允许或拒绝来结束。这里没有定时器；调用方的 `AbortSignal`（提问的那一轮次被取消）是唯一的另一条出路，而且它会把这次取消播报出去，让其他页面不再提供作答入口。请求发出时**并不知道**会不会有人作答——收到它的页面也可能永远不答，所以没有页面连接的部署与其他未作答请求一样挂起，最终以 `cancelled` 收场。`run` 没有 wire 面——`cordis_run` 在进程内调用它。
-- `runHostHalf`／`getClientCode` 是获得允许的页面依次走的步骤，host 半在先，因此 host 半失败会在浏览器还没动作之前短路。`runHostHalf` 在约定上是幂等的：已在运行的包只做绑定，不再求值；针对同一个定义的并发调用只求值一次，`startedHere` 指出求值的是哪一个调用方。随后 `getClientCode` 把浏览器半的源码交给这一个页面；定义已消失、没有浏览器半、或未在运行时，它会拒绝。代码从不搭乘任何播报，所以这是它到达浏览器的唯一途径。
-- `resolveRequestRun` 用作答页面的结论结束这次往返，并 emit `cordis/request-run-resolved`，让其他每个页面撤下待作答的入口。首答即成；更晚的或未知的 request id 会被接受并忽略。命名了注册表已越过的版本的成功结论会被拒绝而非应用（`accepted: false`，请求仍处于挂起），因为作答的那个页面装载的是一个已不再存活的下发。失败的结论只会在 host 半正是由这次请求求值时才将它回退，因此某个页面装不上自己那一半，绝不会把其他页面正在使用的包停掉。
-- `stop` 回退一次存活的下发——丢弃 handler、把 host 半 fiber dispose（资源释放）到完全停稳、emit `dynamicCordisRunner/retract`——并让该定义仍然可运行。
-- `inventory` 回答整个注册表，不按会话寻址，且每一行都指明拥有该定义的会话，因为运行控制面是全局的。能列出不等于能操作：每个有实际动作的动词仍会检查这份归属。每一行还会指明该定义有没有浏览器半，因此运行控制面只在确有可装载的半时，才提供「装入当前页面」。`snapshot` 是它按会话限定的 host 本地对侧，携带每个存活 host 半的 fiber，供 `cordis_inspect` 自行渲染 provides／waiting／state（fiber 无法跨 wire）。
-- `reportRenderFailure` 记录某个页面看到一个**已装载**的浏览器半在渲染时做错了什么。渲染严格发生在装载成功之后，因此到那时 run 早已回答了 `ok`：这份上报是 fire-and-forget 的，不带任何结算权威，也绝不触碰 `resolveRequestRun` 或 run 结论的任何部分——**它不是那个已退役的 v2 `report`／ack**。host 按定义保留跨所有页面的最后一次失败（第二个页面上报即覆盖），而一次全新的 run、一次 stop 或一次 undefine 都会清掉它，因此模型绝不会看到一次已不存在的下发留下的失败。浏览器半的契约面自己保留一份「**这个页面**当前正在显示什么」；两者回答的是不同的问题，不是同一个问题的两份答案。上报的会话若并不拥有该定义，这次上报会被丢弃，因为上报路径绝不能让一次渲染失败。
-- `invoke` 把一个包的浏览器半发起的一次调用，路由到它自己的 host 半用 `harness.handle` 注册的方法。这套基础设施只做路由：不存在 host 到浏览器的方向。

-`run` 或 `stop` 的拒绝会给出 `definition-missing`、`host-half-failed`、`client-half-failed`、`rejected`、`cancelled`、`not-running` 之一；后三者是答复而非缺陷——有人拒绝了、提问的那一轮次已结束，或本来就没有在运行的东西可停。
+-----
 
-别的会话登记的定义读起来是不存在，而不是被禁止，因此不会跨会话泄漏任何东西。`invoke` 与 `resolveRequestRun` 完全不携带会话：组件的一次调用和页面的一次作答都是页面全局的事实，不属于某一个会话。
+<a id="use-this-package"></a>
+## 使用本包
 
-本功能拥有四条转发事件，由本包在其 client-safe 的 [`./types`](src/types.ts) 子路径上声明，并由 [`@deepseek-ai/dsh-api-remotes`](../../api/remotes/README.zh.md) 的白名单准许投递——正是这一点让浏览器能经 `ctx.remote.$on` 收到它们：`cordis/request-run`（`{requestId, agentId, id, name, purpose}`——只有元数据，绝无代码）、`cordis/request-run-resolved`（`{requestId, outcome}`）、`dynamicCordisRunner/package`（`{id, name, rev}`），以及 `dynamicCordisRunner/retract`（`{id, rev}`）。后两者是对称的一对运行状态播报：每次全新启动与每次停止都播，与该包有没有浏览器半无关。
+在任何一个应当支持动态包的组合中挂载本插件——它支撑模型的 `cordis_*` 工具，而带浏览器半的包还需要在客户端组合中额外挂载 client runner 与 UI 包。常用路径是显式的：加载本包，按需设置 `vmTimeoutMs`，其余交给工具与浏览器。
 
-## 存储立场
+### 最小配置
 
-注册表就是进程内存，也是唯一真源。会话日志只承载一次 define 调用的元数据，绝不承载它的代码：因此进程重启后确实没有任何定义，这是合理的；而 id 已无法解析的卡片会如实说明这一点，不会假装自己还能运行。本包不向磁盘写任何东西，也不会自动恢复任何定义；刷新过的页面手上什么都没有，直到有人再次运行某个包——正是这一步让它绑定存活的 host 半并重新取回浏览器半。
-
-## 信任立场
-
-vm 沙箱隔离全局变量，但不是安全边界：Node 全局变量不存在，或重定向到 Cordis 服务（`ctx.fs`、`ctx.web`、`ctx.bash` 以及定时器 helper），host 半收到的是不含框架内部机制的 façade，但它声明的服务仍会触达存活运行时。应当像对待 bash 访问一样对待动态包，参见[自引用工具集 Agent Note](../../../.agents/notes/implemented/feature/2026-07-08-self-referential-cordis-toolset.zh.md)。

-## 导出形状
+### run 会做什么
 
-服务包：默认导出 `DynamicCordisRunnerService`（服务键 `dynamicCordisRunner`），`./types` 则承载 `dynamicCordisRunner` remote namespace 与其消费方共享的载荷形状。`define`／`undefine` 的形状留在包内部，因为它们从不跨 wire。
+定义由 `cordis_define` 记录、由 `cordis_run` 激活。只有 host 半的包直接在本进程中激活：它的代码在沙箱中运行。带浏览器半的包变成一次请求：它一直等到有人在一个页面上允许或拒绝，或提问的轮次被取消；作答页面随后先装载 host 半、再装载浏览器半。`mode: "run"` 启动当前包或重启它，`mode: "update"` 切换到另一个包版本。`cordis_stop` 结束一次存活运行——移除该包的 handler 与任何已装载的浏览器 UI——同时保留可再次运行的定义；`cordis_undefine` 停止并忘掉它。
 
+### 定义的去向
+
+定义以会话为界、以进程为本：包只对定义它的会话可见，其他会话读起来是不存在，DSH 重启后一切都消失。会话日志保留一次 define 调用的参数——包括它提交的代码——以及回执；解析出的定义只存于内存注册表。浏览器半只能经一次运行到达页面，因此刷新后的页面手上什么都没有，直到有人再次运行该包。
+
+### 信任立场
+
+沙箱隔离全局变量，但不是安全边界：Node 全局变量不存在，或重定向到 Cordis 服务（`ctx.fs`、`ctx.web`、`ctx.bash` 与定时器 helper），host 半收到的是不含框架内部机制的 façade，但它声明的服务仍会触达存活运行时。对待动态包要像对待 bash 访问一样，参见[自引用工具集 Agent Note](../../../.agents/notes/implemented/feature/2026-07-08-self-referential-cordis-toolset.zh.md)。

+<summary>实现细节——点击展开</summary>
+
+本节解释 runner 背后的设计；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+runner 建立在两个分离之上。**注册表与沙箱是同一个服务。** `DynamicCordisRunnerService` 拥有定义注册表、vm 沙箱、host 半 fiber 生命周期与 invoke handler 表，因此一个定义的整个生命周期只有一个 owner。**版本是不可变的包。** 插件持有 `define` 之后永不变化的包；`currentPackageId` 与 `nextPackageId` 指向运行中与目标版本，`mode: "run"` 与 `"update"` 编码目标是否等于当前版本。浏览器往返之所以存在，是因为浏览器半只能由页面执行：服务 emit 请求并挂起，由页面的结论结算，调用方的 `AbortSignal` 是唯一的另一条出路。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 服务入口：`Config`、注册表接线、生命周期动词、steer 消息 |
+| [`src/registry.ts`](src/registry.ts) | 定义存储：插件与包标识、运行尝试、审批请求 |
+| [`src/sandbox.ts`](src/sandbox.ts) | `node:vm` 求值：全局变量、Node API 陷阱、define 时语法预检 |
+| [`src/guard.ts`](src/guard.ts) | 注册边界：schema 规范化、沙箱 `ctx` façade、插件形态检查 |
+| [`src/lifecycle.ts`](src/lifecycle.ts) | 在 `cordis-dynamic` fiber 组下启动 host 半 |
+| [`src/inspect-registry.ts`](src/inspect-registry.ts) | `ctx.cordisInspect` 注册表：host provider 加镜像的 client manifest |
+| [`src/types.ts`](src/types.ts) | `dynamicCordisRunner` remote namespace 与转发事件共享的 client 安全载荷形态 |
+
+### 一次 run 的流程
+
+`define` 对元数据做首尾去空白与必填校验，用编译预检每一半的语法（不执行任何代码），铸出插件与包标识，并把定义登记在发起调用的会话名下。`run` 对照 `currentPackageId` 与 `nextPackageId` 解析目标：纯 host 包在沙箱中求值并立即提交，带浏览器半的包则挂起一次审批请求、emit `cordis/request-run` 并挂起。作答页面依次走 `runHostHalf`、`getClientCode` 与 `resolveRequestRun`；命名存活 revision 的成功会提交激活、设置 `currentPackageId`，`cordis/request-run-resolved` 让其他每个页面撤下待作答入口。`stop` 回退存活下发——handler disposer、fiber dispose 与 `cordis/dynamic-retract` 广播——并让定义保持可运行。四条转发事件（`cordis/request-run`、`cordis/request-run-resolved`、`cordis/dynamic-package`、`cordis/dynamic-retract`）声明在 client 安全的 `./types` 子路径上，并由 `@deepseek-ai/dsh-api-remotes` 的白名单准许投递——正是这一点让浏览器能经 `ctx.remote.$on` 收到它们。

-没有直接可见的内容：本包不注册任何工具，也不注入提示词。它的拒绝经调用它的 `cordis_*` 工具结果到达模型——无法解析的半会指出出错的那一行，缺失的定义会解释定义只活在内存里，`rejected` 或 `cancelled` 的 run 报告的是有人拒绝或该轮次已结束而非出了故障，浏览器半装载失败则带上作答页面自己的错误文本。

 #### Token 影响
 
-本包自身没有：上述每条消息都由调用它的那个工具的结果承载。
+有条件且随数据而定：消息只在事件发生时到达，每条都携带一段有界的说明；没有固定的每请求成本。
 
 #### KV Cache 影响
 
-注册工具的 host 半会改变下一次请求的工具视图，从第一个变化的 schema token 起使前缀复用失效；运行或停止一个不注册任何工具的包对前缀不产生影响。

 <a id="known-limitations-and-deferred-work"></a>
 
-## 已知限制与暂缓事项
 
-- **run 成功不等于 UI 渲染成功。** 只要作答页面**已装载**浏览器半，`run` 就会返回；React 是随后才渲染的，因此一个抛异常的组件根本不可能出现在 run 的回执里。该失败经 `reportRenderFailure` 浮现，并通过 `cordis_inspect what:"temporary"` 读回；run 的结果会把这一点说出来，而不是暗示成功。
+这些限制说明 runner 何时需要特别小心。它们是当前包约束，不是任务积压。
 
-- 带浏览器半的包在**没有页面连接的地方会挂起**——headless 与 ACP（Agent Client Protocol）部署会把这次 run 一直挂到提问的轮次被取消，因为转发事件不回报谁收到了它。只有 host 半的包不受影响。
-- 挂起的 run 请求**没有超时**：它一直等人，直到提问的那一轮次被取消，因此无人值守的自动化用不了带浏览器半的包。
-- `vmTimeoutMs` 只约束同步求值；async 的 host 半函数体会逃出该上限，这与该工具集基于协作的信任立场一致。
-- `runHostHalf` 不携带 request id，因此「这个 host 半是哪次请求求值的」由 host 侧归因到该定义最近一次挂起的请求；若同一个定义出现多个并发 run 请求，这条规则需要重新审议。
-- 命名了已被取代版本的成功结论会被拒绝（`accepted: false`）并让该请求继续挂起，因此模型这次调用只能靠一次有效作答或自身被取消才结束。要把它结算掉，需要对着存活版本重新走一遍编排，而没有任何页面执行这套编排——[浏览器半](../cordis-client-runner/README.zh.md)不读这个 ack——所以这类请求实际上由别的页面作答、或由调用方取消来收尾。
-- 浏览器半声明的 `inject` 是从它在页面里返回的插件上读出的，因此播报完全不携带服务声明字段。
-- **`zod` 是生成的 TypeRT 契约面的运行时依赖，不是 `src` 的依赖。** `./typert` 与 `./remote` 解析到 `lib/typert.*.js`，`tsc` 以不打包的形式产出它们，其中带有裸的 `import { z } from 'zod'`，所以本包必须声明它（沿用 `@deepseek-ai/dsh-goal` 的先例），而 `knip.json` 必须在这个 workspace 里忽略它：knip 读的是源码，而这些契约面是构建产物。`src` 里没有任何代码 import zod。
+- **run 成功不等于 UI 渲染成功**——只要作答页面已装载浏览器半，`run` 就会返回；React 是随后才渲染的，因此抛异常的组件不可能出现在 run 回执里。该失败经 steer 与 `cordis_inspect_self` 诊断浮现。
+- **带浏览器半的包在没有页面连接的地方挂起**——headless 与 ACP（Agent Client Protocol）部署会把 run 一直挂到提问的轮次被取消；纯 host 包不受影响。
+- **挂起的 run 请求没有超时**——它一直等人，直到提问的轮次被取消，因此无人值守的自动化用不了带浏览器半的包。
+- **`vmTimeoutMs` 只约束同步求值**——async 的 host 半函数体会逃出该上限，这与工具集基于协作的信任立场一致。
+- **陈旧成功的拒绝会让请求继续挂起**——作答页面点名的 revision 已被注册表越过时，该结论会被拒绝（`accepted: false`），请求保持可作答，直到另一个页面作答或调用方取消；浏览器半不读这个 ack。
+- **运行播报不携带服务声明**——浏览器半声明的 `inject` 是从它在页面里返回的插件上读出的，因此 `cordis/request-run` 只携带元数据，绝无代码或服务清单。
+- **`zod` 是生成的 Typert 契约面的运行时依赖，不是 `src` 的依赖**——`./typert` 与 `./remote` 解析到未打包的 `lib` 文件，其中带有裸的 `import { z } from 'zod'`，所以本包声明它，`knip.json` 也在这个 workspace 里忽略它；`src` 里没有任何代码 import zod。

 # @deepseek-ai/dsh-tool-cordis
 
 English | [中文](README.zh.md)
 
-The self-referential Cordis toolset: five model-facing tools over the live runtime in the current DSH process. The registry, the vm sandbox, and the browser broadcast belong to [`@deepseek-ai/dsh-cordis-host-runner`](../cordis-host-runner/README.md) (`ctx.dynamic`), which this toolset injects — a composition with these tools but no runner never activates them. Design home — sandbox semantics, dynamic-package lifecycle and composition, standing decisions: [the toolset Agent Note](../../../.agents/notes/implemented/feature/2026-07-08-self-referential-cordis-toolset.md).
+## Summary
 
-## What it does
+`dsh-tool-cordis` gives the model seven tools over the live Cordis runtime of the current DSH process: inspect what is loaded and what a dynamic package may use, define a package with a host half, a browser half, or both, run it, stop it, and remove it. Packages are versioned — a plugin holds immutable package versions, and the model can append a corrected package and update to it after a failure. Definitions live only in process memory and vanish on DSH restart; nothing here writes repository files, installs packages, or changes `cordis.yml`. It also adds a system-prompt section that teaches the workflow; compose it with `@deepseek-ai/dsh-cordis-host-runner`, the package that runs the sandbox and the run round trip.
 
-Two paired verbs, plus the read-only report.
+## Table of Contents
 
-- `cordis_inspect` — read-only report over the current process: services, all live plugin fibers, registered tools, this session's dynamic packages, the reflection-backed `api` / `events` references, and the compile-time `client` slot surface a browser half can contribute UI into. An exact `name` with `what: "api"`, `what: "events"`, or `what: "client"` narrows the report and adds the full contract.
-- `cordis_define` — records a package (`name`, `purpose`, and a host half `code` and/or a browser half `client`) after syntax-checking both halves. Nothing runs; the user sees a card for it in the conversation with a start control. The minted `dyn-<n>` id rides the result value AND the durable presentation metadata, which is how that card addresses the run verbs on replay.
-- `cordis_run` — evaluates the host half in the sandbox and delivers the browser half to every open web page. Running an already-running package re-delivers the live version instead of failing, which is how a reloaded page gets it back.
-- `cordis_stop` — disposes the host half to quiescence and withdraws the browser half; the definition survives and can run again.
-- `cordis_undefine` — stops the package if needed and forgets the definition; its card stays in the conversation as an unloaded record.

-Exact model-facing schemas: [the generated tool catalog](../../../docs/tool-catalog.md).
+-----
 
-Dynamic packages live only in the shared DSH process memory. They remain active across later turns and may affect other sessions in that process, but disappear after `cordis_stop`/`cordis_undefine`, toolset unload, or DSH restart. They create no Plugin file, install no package, change no `cordis.yml` or personal/project configuration, do not survive restart, and cannot be promoted automatically. To keep an experiment, ask the Agent to implement a normal local, project, or repository Plugin through the regular development workflow. Every verb is session-scoped: a package is visible and controllable only in the session that defined it.
+<a id="use-this-package"></a>
+## Use this package
 
-## Trust stance
+Mount this plugin when a session should be able to extend its own runtime temporarily — for example, a model-written tool, service, or browser UI that helps the current work but should not become a repository plugin. Compose it with the host runner; without the runner the tools never activate, and no shipped bundle mounts the toolset (the web profile already mounts the host runner and the browser faces), so add the tool row explicitly.
 
-The sandbox isolates globals but is not a security boundary. Node globals are absent or redirect to Cordis services such as `ctx.fs`, `ctx.web`, and `ctx.bash`, and writes to `globalThis` stay local, but host-realm helpers make escape possible. Mounted plugins receive a façade without framework internals, yet its allowed services affect the live runtime. Dynamic tool schemas and annotations cross the realm through iterative JSON cloning and schema normalization, so valid deep declarations are memory-bounded rather than call-stack-bounded; records with JSON-invisible keys and subclassed or decorated schema arrays reject before normalization. Treat this toolset like bash access; see the [design and trust stance](../../../.agents/notes/implemented/feature/2026-07-08-self-referential-cordis-toolset.md).
+### Minimal composition
 
-## Config
+```yaml
+- name: '@deepseek-ai/dsh-cordis-host-runner'
+  config:
+    vmTimeoutMs: 5000
+- name: '@deepseek-ai/dsh-tool-cordis'
+```
 
-None. The vm evaluation bound (`vmTimeoutMs`) and the browser acknowledgement window (`ackTimeoutMs`) belong to the runner service that owns the sandbox and the broadcast — see [`@deepseek-ai/dsh-cordis-host-runner`](../cordis-host-runner/README.md#config).
+The CLI example [`apps/cli/config/examples/cordis/cordis.yml`](../../../apps/cli/config/examples/cordis/cordis.yml) composes both. A package with a browser half additionally needs the browser runner and the UI package in the client composition; a host-only package needs none of them.
 
-## The generated client slot catalog
+### What the tools do
 
-`src/client-catalog.ts` describes the browser half's seats, generated by `scripts/gen-client-catalog.ts` (freshness-gated by `pnpm run verify-client-catalog` in `doc-sync`) from a lexical scan of every `SlotMap` declaration merge and every `slots.register` call site. It carries the one surface a browser half can act on — the slot keys, each register call's options, the props a component receives, who already occupies the seat, and which owner's mount makes the seat exist — as plain data: this package stays host-side and imports no client module, so the strings are the only thing that crosses. The generator fails loud rather than shipping an entry a model cannot act on: a slot with no registrant-facing prose, a non-literal `kind`/`scope`, owner props no export provides, a duplicate key, or a registration into an undeclared slot all break the gate. Owner props expand one level — the owner declaration with its own member documentation, and the names of the shapes its fields reference — and one slot's whole report is budget-capped, because narrowing to a single slot exists to spend less context, not more.
+The three inspect tools are read-only; the four lifecycle tools define and manage packages. All results are JSON rendered as text.
 
-A slot's teaching text is its declaration's JSDoc, so improving what the model reads means editing the contract at its declaring package — not this catalog.
+- `cordis_inspect_list` — list the Inspect Providers (host and client) and their query methods.
+- `cordis_inspect_query` — run one provider query: exact service methods, event modes, builtin signatures, tool schemas, theme tokens, or live slot trees.
+- `cordis_inspect_self` — this session's dynamic plugins: version pointers, latest run, and, for one exact package, its source and runtime diagnostics.
+- `cordis_define` — record a package: a new plugin (`plugin.kind: "new"` with a 3–6-letter `idPrefix`) or a new version of an existing plugin (`plugin.kind: "existing"` with its `pluginId`). It validates parameters and syntax only; nothing runs and no approval is requested.
+- `cordis_run` — activate one package (`mode: "run"` for the first activation or restart, `mode: "update"` to switch versions). A package with a browser half may return `awaiting-approval` until a person allows it; the tool never waits for the final outcome.
+- `cordis_stop` — stop the current run and cancel any pending approval, keeping the plugin and every package version.
+- `cordis_undefine` — stop and permanently remove a plugin and all of its packages.
 
-## Where the API report comes from
+### A typical workflow
 
-`cordis_inspect what:"api"` / `what:"events"` renders `src/api-catalog.ts`, the generated projection of the workspace's Cordis declarations: rendered method signatures, source JSDoc, harness events with their dispatch modes, and the type shapes those signatures reference, all produced by the same AST walk as `docs/subsystems`, so the data a model reads and the rendered docs cannot diverge. It is a compile-time fact about the REPOSITORY, so `pnpm run gen-cordis-api` regenerates it and `pnpm run verify-cordis-api` gates its freshness.
+Inspect before writing, then define, then run: `cordis_inspect_query` reads the exact contract of the service or slot the package will use, `cordis_define` records the source (and the conversation shows a define card pointing to the panel where the run control lives), and `cordis_run` activates it. When the user types `@pluginId`, this package injects a context message that pins the referenced plugin, its base package, and the update path. After a technical failure, read the diagnostics with `cordis_inspect_self`, append a corrected package to the same plugin, and update to it.
 
-`src/inspect.ts` intersects that catalog with the LIVE service store: what is RUNNING comes from the store, what each service CAN DO comes from the catalog, and a live service the catalog does not cover is reported as reachable with no signatures rather than omitted. A package that needs the list in its own code copies it out of a report — the catalog is a compile-time fact about the repository, so a copied list and a freshly read one say the same thing for any one deployment.
+### Boundaries to plan around
 
-Two model-facing judgements live in this package rather than in the artifacts, because reflection data is faithful to the code while a report has to be useful:
+Definitions are session-scoped and process-local: a package is visible and controllable only in the session that defined it, stays active across later turns, and can affect other sessions in the same process while running. Stopping, removing, unloading the toolset, or restarting DSH clears it. The sandbox isolates globals but is not a security boundary — treat a dynamic package like bash access, and load this plugin as deliberately as you would grant one.
 
-- **Only callable methods are shown.** Non-method members are state rather than a verb, and their rendered form carries initializers from the implementation body; symbol-keyed members are internal seams between plugins that a package façade deliberately cannot reach, so naming one would advertise a call that cannot be made.
-- **Only keys a host half can reach are named to a model.** The reflection model covers every `ctx.<key>` a package declares, including launcher-supplied boot values (`agent`, `headlessIo`, …) and browser-half services (`connection`). `src/curation.ts` classifies each one's `reach` — `injectable`, `not-a-service`, or `other-face` — and only `injectable` keys reach a report: naming a key a package cannot reach advertises a call that cannot be made. The classification is carried as data on each catalog entry rather than applied while rendering, so the exclusion is testable on its own, and `verify-cordis-catalog` pins the classified set to exactly the keys the documentation projection does not render — a newly declared key stops the gate instead of quietly inviting a model to `inject` something that will never arrive. A classified key that nonetheless has a live provider is still reported as running and injectable: the service store is the authority on what exists.
+-----
 
-The generated `INHERITED_CTX_API` closes the `api` report with the framework-inherited `ctx` surface (`ctx.on`, `ctx.effect`, `ctx.loader`, the timer helpers): those members are the Context itself rather than service keys, and the framework tier lives in pinned vendor packages outside every analyzed face, so the generator curates that one tier and renders it into both this catalog and `docs/cordis-api/inherited.md`. A live service the catalog does not describe is reported as running and still injectable rather than as absent. Broad `api` / `events` reports render summaries and signatures only; an exact `name` opts into the retained method/event JSDoc, and unknown or non-running service targets fail loud.

-Every tool renders a `generic` card (`read` / `execute` / `delete`); `cordis_define` carries the submitted halves as `rawInput` and titles the card with the label and purpose. Presenters are pure functions of the args, and results keep the default text rendering. A Web client registers its own keyed `cordis_define` row (`@deepseek-ai/dsh-client-ui-cordis`) and reads the label, purpose, and minted id from the call arguments and the result metadata; the generic card is what a surface without that registration falls back to.
+This section explains the design behind the tools; the observable behavior is fully covered in [Use this package](#use-this-package).
 
-## Export shape
+### Design philosophy
 
-Namespace plugin: named exports `name` / `inject` / `apply`, no default export ([docs/postmortem/0001](../../../docs/postmortem/0001-acp-default-export-drops-inject.md)). It injects `tools` and `dynamicCordisRunner`.
+The toolset is built on one separation: the tools are a thin, model-facing layer over the runner service. Inspection data comes from generated catalogs intersected with the live service store; definition and lifecycle verbs delegate to `ctx.dynamicCordisRunner`, which owns the registry, the vm sandbox, and the browser round trip. The tools add the model-facing judgments: only callable methods are shown, only keys a host half can reach are named, and every refusal is a teaching error the model can act on.

+
+### How a call flows
+
+An inspect call queries `ctx.cordisInspect`: host providers run locally, client providers wait for the first valid page response. Define prechecks each half's syntax by compiling it in the same wrapper the sandbox uses, so unparseable code is refused before an id exists. Run delegates to the runner, which activates host-only packages in-process and suspends browser-half packages on a `cordis/request-run` round trip; the tool returns the runner's receipt (`awaiting-approval`, `starting`, or `running`). When the user writes `@pluginId`, an `agent/pre-step` handler reads the reference and injects a user-role context message naming the base package and the required next steps.

 ### Tool-call history and results
 
 #### What the model sees
 
-Inspect joins selected sections exactly as `## <section>` then a newline and the data-dependent body, with one blank line between sections; `what: "temporary"` uses the `## Dynamic Packages` heading. Each row reports the id, label, purpose, which halves exist, run state and revision, provided and awaited services, registered host methods, and the last browser-half load report. The empty state explains that definitions live only in this process's memory. Broad API/event reports omit JSDoc; `name` with `what: "api"`, `what: "events"`, or `what: "client"` returns one exact target with its full contract. The `client` section lists one seat per line with its cardinality, scope, summary, and whether registering there replaces shipped UI, then the cross-cutting registrant rules; the per-seat register options, owner and framework props, and runnable example arrive only under an exact `name`. Define answers that the package is defined and NOT running yet with the id to run; run reports the revision, what the host half provides or waits for, and whether a page acknowledged the browser half; stop and undefine acknowledge in one line. Every refusal is a tool error carrying the runner's teaching text. The submitted program remains in assistant tool-call history.
+Inspect outputs are JSON rendered as text: `cordis_inspect_list` returns the provider directory, `cordis_inspect_query` the queried data, and `cordis_inspect_self` a plugin, version, and package summary with source and diagnostics for an exact package. Define answers that the package is defined and not running yet, with the ids to run. Run reports `awaiting-approval`, `starting`, or `running` with the run id and version pointers.

 # @deepseek-ai/dsh-tool-cordis
 
 [English](README.md) | 中文
 
-自引用 Cordis 工具集：五个面向模型的工具，操作当前 DSH 进程中的实时运行时。注册表、vm 沙箱与浏览器广播属于 [`@deepseek-ai/dsh-cordis-host-runner`](../cordis-host-runner/README.zh.md)（`ctx.dynamic`），本工具集注入它——只装这些工具而不装 runner 的组合永远不会激活它们。沙箱语义、动态包生命周期与组合及既定决策详见[工具集 Agent Note](../../../.agents/notes/implemented/feature/2026-07-08-self-referential-cordis-toolset.zh.md)。
+## 概述
 
-## 功能
+`dsh-tool-cordis` 给模型提供七个作用于当前 DSH 进程实时 Cordis 运行时的工具：检查已加载的内容与动态包可用之物，定义包含 host 半、浏览器半或两者的包，运行它、停止它并移除它。包带版本——插件持有若干不可变的包版本，模型在失败后可以追加修正版并更新过去。定义只存在于进程内存中，DSH 重启即消失；本包不写仓库文件、不安装任何包、不改 `cordis.yml`。它还增加一个教这套工作流的系统提示词章节；把它与 `@deepseek-ai/dsh-cordis-host-runner` 一同组合，后者负责沙箱与运行往返。
 
-两组配对动词，外加只读报告。
+## 目录
 
-- `cordis_inspect`：当前进程运行时的只读报告，包括服务、全部存活插件 fiber、已注册工具、本会话的动态包、反射支持的 `api`／`events` 参考，以及浏览器半可以向其贡献 UI 的编译期 `client` 槽面。精确的 `name` 配合 `what: "api"`、`what: "events"` 或 `what: "client"` 可缩窄报告，并附上完整约定。
-- `cordis_define`：在语法预检两个半之后登记一个包（`name`、`purpose`，以及 host 半 `code` 和／或浏览器半 `client`）。此时不运行任何东西；用户会在会话里看到它的卡片和一个启动控件。铸出的 `dyn-<n>` 标识同时进入结果 value **与**持久的呈现元数据，卡片正是靠后者在 replay 中寻址运行动词。
-- `cordis_run`：在沙箱中求值 host 半，并把浏览器半投递给每个打开的网页。对已在运行的包再次运行不会失败，而是重新投递当前版本——这正是被刷新过的页面把包取回来的方式。
-- `cordis_stop`：把 host 半 dispose 到完全停稳，并从各页面撤回浏览器半；定义存续，可以再次运行。
-- `cordis_undefine`：必要时先停止该包，再忘掉定义；它的卡片作为一条已卸载记录留在会话里。

+-----
 
-动态包只存在于共享 DSH 进程内存中。它可跨后续轮次保持活跃，也可能影响同一进程中的其他会话，但会在 `cordis_stop`／`cordis_undefine`、工具集卸载或 DSH 重启后消失。它不会创建插件文件、安装任何包、修改 `cordis.yml` 或个人／项目配置、跨重启存续，也不能自动转为正式插件。若要保留实验结果，应让 agent（智能体）通过常规开发流程实现普通的本地、项目或仓库插件。每个动词都以会话为界：一个包只在定义它的那个会话里可见、可控。
+<a id="use-this-package"></a>
+## 使用本包
 
-## 信任立场
+当某个会话应当能临时扩展它自己的运行时——例如一个对当前工作有用、但不应成为仓库插件的模型编写的工具、服务或浏览器 UI——挂载本插件。请与 host runner 一同组合；没有 runner，这些工具永远不会激活，而且任何已发布的 bundle 都不会挂载这套工具集（web profile 已挂载 host runner 与浏览器侧组件），所以要显式地添加工具行。
 
-该沙箱隔离全局变量，但不是安全边界。Node 全局变量不存在，或会重定向到 `ctx.fs`、`ctx.web`、`ctx.bash` 等 Cordis 服务；写入 `globalThis` 的内容保持局部，但 host realm helper 使逃逸成为可能。运行中的 host 半收到不含框架内部机制的 façade，但获准服务仍会影响存活运行时。动态工具 schema 与 annotation 通过迭代式 JSON 克隆和 schema 规范化跨越 realm，因此有效的深层声明受内存而非调用栈限制；含 JSON 不可见 key 的 record，以及子类化或装饰过的 schema array，会在规范化前被拒绝。应当像对待 bash 访问一样对待该工具集；参见[设计与信任立场](../../../.agents/notes/implemented/feature/2026-07-08-self-referential-cordis-toolset.zh.md)。
+### 最小组合
 
-## 配置
+```yaml
+- name: '@deepseek-ai/dsh-cordis-host-runner'
+  config:
+    vmTimeoutMs: 5000
+- name: '@deepseek-ai/dsh-tool-cordis'
+```
 
-无。vm 求值边界（`vmTimeoutMs`）与浏览器确认窗口（`ackTimeoutMs`）属于拥有沙箱与广播的 runner 服务——见 [`@deepseek-ai/dsh-cordis-host-runner`](../cordis-host-runner/README.zh.md#config)。
+CLI 示例 [`apps/cli/config/examples/cordis/cordis.yml`](../../../apps/cli/config/examples/cordis/cordis.yml) 同时组合了这两者。带浏览器半的包还额外需要客户端组合里的浏览器 runner 与 UI 包；纯 host 包则两者都不需要。
 
-## 生成的 client 槽目录
+### 工具能做什么
 
-`src/client-catalog.ts` 描述浏览器半的座位，由 `scripts/gen-client-catalog.ts` 生成（新鲜度门禁为 `doc-sync` 中的 `pnpm run verify-client-catalog`），数据来自对每一处 `SlotMap` 声明合并与每一个 `slots.register` 调用点的词法扫描。它承载浏览器半唯一能动的那个面——槽键、每个 register 调用的选项、组件会收到的 props、谁已经占着这个座位、以及哪个 owner 挂着这个座位才存在——并且只以纯数据承载：本包始终在 host 侧、不 import 任何 client 模块，跨越两平面的只有这些字符串。生成器宁可高声失败也不吐出一条模型无法照做的条目：槽缺少面向 registrant 的 JSDoc 正文、`kind`／`scope` 不是字面量、owner props 没有任何导出声明、键重复、或注册进了没人声明的槽，都会让门禁变红。owner props 只展开一层——owner 声明本身连它的成员文档,加上其字段所引用的那些形状的名字——而单个槽的整份报告有行数上限:收窄到一个槽的意义是少花上下文,不是多花。
+三个检查工具只读；四个生命周期工具定义并管理包。所有结果都是渲染成文本的 JSON。
 
-一个槽的教学文案就是它声明处的 JSDoc，所以要改模型读到的内容，改的是声明它的那个包里的约定，而不是这份目录。
+- `cordis_inspect_list`——列出 Inspect Provider（host 与 client）及其查询方法。
+- `cordis_inspect_query`——执行一次 provider 查询：精确的服务方法、事件分发模式、builtin 签名、工具 schema、主题 token 或实时 slot 树。
+- `cordis_inspect_self`——本会话的动态插件：版本指针、最近一次运行，以及（对某个精确包而言）源码与运行时诊断。
+- `cordis_define`——登记一个包：新插件（`plugin.kind: "new"`，配 3–6 个字母的 `idPrefix`），或既有插件的新版本（`plugin.kind: "existing"`，配其 `pluginId`）。它只校验参数与语法；不运行任何东西，也不请求审批。
+- `cordis_run`——激活一个包（首次激活或重启用 `mode: "run"`，切换版本用 `mode: "update"`）。带浏览器半的包可能先返回 `awaiting-approval`，直到有人允许；工具从不等待最终结果。
+- `cordis_stop`——停止当前运行并取消任何待审批请求，保留插件与全部包版本。
+- `cordis_undefine`——停止并彻底移除一个插件及其全部包。
 
-## API 报告从哪里来
+### 典型工作流
 
-`cordis_inspect what:"api"`／`what:"events"` 渲染的是 `src/api-catalog.ts`，即工作区 Cordis 声明的生成投影：渲染好的方法签名、源码 JSDoc、带分发模式的 harness 事件，以及这些签名引用到的类型形状——全部由与 `docs/subsystems` 同一次 AST 遍历产出，因此模型读到的数据与渲染出的文档不可能彼此偏离。它是关于**仓库**的编译期事实，所以用 `pnpm run gen-cordis-api` 重新生成、用 `pnpm run verify-cordis-api` 守它的新鲜度。
+先检查、再定义、后运行：`cordis_inspect_query` 读取包要用的服务或 slot 的精确约定，`cordis_define` 记录源码（会话里会出现一张 define 卡片，指向存放运行控件的面板），`cordis_run` 激活它。当用户输入 `@pluginId` 时，本包注入一条上下文消息，钉住所引用的插件、其基准包与更新路径。技术性失败之后，用 `cordis_inspect_self` 读取诊断，向同一插件追加修正版，再更新过去。
 
-`src/inspect.ts` 把这份目录与**活的**服务存储取交集：**谁在跑**由存储回答，**每个服务能做什么**由目录回答；目录没覆盖到的活服务会被报成可达但没有签名，而不是被省略。包代码若要在自己源码里用这份清单，就从报告里抄出来——目录是关于仓库的编译期事实，所以对任一个部署而言，抄出来的清单与现读的清单说的是同一件事。
+### 需要规划的边界
 
-有两项面向模型的判断住在本包里，而不住在产物里，因为反射数据忠于代码，而报告必须有用：
+定义以会话为界、以进程为本：包只在定义它的会话里可见可控，可跨后续轮次保持活跃，运行时也可能影响同一进程中的其他会话。停止、移除、卸载工具集或重启 DSH 都会清除它。沙箱隔离全局变量，但不是安全边界——对待动态包要像对待 bash 访问一样，加载本插件时也要像授予 bash 工具那样慎重。
 
-- **只展示可调用的方法。** 非方法成员是状态而不是动词，而它们渲染出来的形式会带上实现体里的初始值；以 symbol 为键的成员是插件之间的内部 seam，包的 façade 刻意无法触达，所以点出其中任何一个，都等于宣传一次根本发不出的调用。
-- **只有 host 半够得到的键，才会被点名给模型。** 反射模型覆盖包声明的每一个 `ctx.<key>`，其中包括 launcher 提供的 boot 值（`agent`、`headlessIo` 等）与浏览器半的服务（`connection`）。`src/curation.ts` 会为每一个这样的键归类它的 `reach`——`injectable`、`not-a-service` 或 `other-face`——而只有 `injectable` 的键能进报告：点名一个包够不到的键，就等于宣传一次根本发不出的调用。这份归类是作为每条目录条目上的数据携带的，而不是在渲染时才施加，因此这项排除可以单独测试；同时 `verify-cordis-catalog` 把被归类的集合钉成「文档投影不渲染的键」这个集合本身——新声明一个键会把门禁拦下来，而不是悄悄引诱模型去 `inject` 一个永远不会到来的东西。一个被归类、但确实有存活提供方的键，仍然会被报成在跑且可 inject：服务 store 才是「什么存在」的权威。
+-----
 
-生成常量 `INHERITED_CTX_API` 为 `api` 报告收尾，列出框架继承来的 `ctx` 面（`ctx.on`、`ctx.effect`、`ctx.loader`、各 timer 辅助方法）：这些成员本身就是 Context，不是某个服务键；而框架层住在 pinned vendor 包里，位于每一个被分析的契约面之外——所以生成器策展这**一层**，并把它同时渲染进本目录与 `docs/cordis-api/inherited.md`。一个活着、但目录并不描述的服务，会被报成“在跑、且仍可 inject”，而不是报成不存在。宽泛的 `api`／`events` 报告只渲染摘要与签名；精确 `name` 会选择保留的方法／事件 JSDoc，未知或未运行的服务目标会高声失败。

-每个工具都渲染 `generic` 卡片（`read`／`execute`／`delete`）；`cordis_define` 以 `rawInput` 携带提交的两个半，并用标签与用途作为卡片标题。presenter 是 args 的纯函数，结果保留默认文本渲染。Web 客户端注册自己的 keyed `cordis_define` 行（`@deepseek-ai/dsh-client-ui-cordis`），从调用参数与结果元数据里取标签、用途和铸出的标识；没有该注册的界面则退回到这张 generic 卡片。
+本节解释工具背后的设计；可观察行为已在[使用本包](#use-this-package)中完整说明。
 
-## 导出形式
+### 设计理念
 
-Namespace 插件：命名导出 `name`／`inject`／`apply`，无默认导出（[docs/postmortem/0001](../../../docs/postmortem/0001-acp-default-export-drops-inject.zh.md)）。它注入 `tools` 与 `dynamicCordisRunner`。
+工具集建立在一个分离之上：工具是 runner 服务之上薄薄的一层模型面向层。检查数据来自生成的目录与实时服务存储的交集；定义与生命周期动词委托给 `ctx.dynamicCordisRunner`，它拥有注册表、vm 沙箱与浏览器往返。工具负责模型面向的判断：只展示可调用的方法、只点名 host 半够得到的键，并且每次拒绝都是模型可以直接行动的教学错误。

-Cordis dynamic-plugin surfaces, browser half: a frame-wide panel that operates every definition the host holds, and a read-only `cordis_define` card that records what a session defined.
+## Summary
 
-**The panel is global on purpose.** A model-driven `cordis_run` blocks host-side on a `cordis/request-run` round trip whose answer is a person pressing approve, and it can name a definition belonging to a session nobody is looking at — an approval reachable only inside that session's transcript would be unreachable exactly when it blocks the model. So the answering surface is a `shell.overlay` entry (a generic frame-wide floating seat this package contributed to `ui-layout`, not a React root of its own): a badge counting what runs plus what waits, opening a list of every definition with its run controls. The list is never filtered by session for the same reason; the selected session's rows are grouped first and everyone else's stay listed below. Rows come from the host's global `inventory` call, re-read rather than patched whenever an announcement changes what exists, because the announcements carry no labels. An open request whose definition that read does not cover still gets a row, rendered from the run activity's own session, label, reason and request identity: `cordis_define` broadcasts nothing, so a package defined after the last read is unknown to the page while its request already blocks the model, and a badge counting an answer the list cannot show would strand it. Such a request also triggers one registry read, which brings the row its run controls. Grouping reads one resolved field per row — the live run's session when there is one, the registry row's otherwise — rather than a different store per phase; both activity arms carry it, so answering a request cannot make its row leave the group it was answered in. Within a group the rows blocking a model come first.
+`dsh-client-ui-cordis` gives a web client the browser surfaces for dynamic Cordis packages: a frame-wide panel that operates every definition the host holds, tool cards that render `cordis_define`, `cordis_run`, `cordis_stop`, and `cordis_undefine` calls in the conversation, and an `@pluginId` input source that completes the session's defined plugins. The panel is global on purpose — a model-driven run blocks on a person's approval, and that approval must be reachable no matter which session is in view. The package authors nothing the model sees: everything it operates comes from the browser runner and the host's inventory, and the cards render call and result content the conversation already logged.
 
-**The card is a record.** It shows the name and purpose the model wrote, the source it wrote, and whether that definition is running — no switch, no approval, and a pointer to the panel. Its material comes only from the frozen call/result slice (labels from `argsRaw`, the host-minted id from the result's `meta.id`), so replay renders the same card, and one reading is the card's own to own: a successful `cordis_undefine` in this session's log is durable and terminal, and outranks the wire, where a retract announcement looks identical to a plain stop.
+## Table of Contents
 
-**A row reads two independent facts.** What the host runs comes from the inventory; what THIS page has loaded comes from the runner's live set. They diverge on every reload: the host keeps running everything while a fresh page holds nothing. A row the host runs and this page holds offers the global stop; a row the host runs and this page does NOT hold offers the load back first and that stop second — separate controls, because loading the browser half here and stopping the definition for every page are different acts. A host-only definition is exempt from all of it: with no browser half to load, "this page does not hold it" is simply what it always looks like, so its row reads plainly running and offers the stop alone. Idle, it offers a run labelled as just that — nothing is loaded here, so the control does not say it is — and the run request carries `hasClientHalf` to the runner, which is what makes it bring up the host half and fetch no browser half. Collapsing the two facts into the host's `running` alone left a reloaded page with nothing but the global stop, so the documented reload recovery (pull the inventory, load the definition back into this page) had no control to go through.

-**A crash after a successful load still belongs on the row.** A browser half can load, answer `cordis_run` with ok, and only then throw when React renders it — the teaching error for a mistake like reaching for `setInterval` reaches the browser console, which neither the model nor the person watching the panel reads. So the row carries the runner's last render failure for this page inline, in the same slot as a load failure: one is "it never loaded", the other "it loaded and then threw", and a row can honestly show both. The line names the seat that crashed and answers the question that follows from it — whether anything of theirs is still on screen: a shadowing seat retires the crashed entry and the shipped UI comes back, while a chain entry keeps its place and its UI may simply be incomplete.
+-----
 
-Neither surface keeps run state in component state — settling a define call moves its card in the chat flow, which remounts it. Facts live in observables owned by whoever can close them: the browser-side runner owns open requests, orchestration outcomes (it resolves them, including when another page answers first), this page's live set and its render failures — it is the only party watching `slots.onEntryError` and the only one that can map a crashed entry back to the package that registered it — and this package owns the inventory it read and the announcements it folded.
+<a id="use-this-package"></a>
+## Use this package
 
-The `/client` export surface is the plugin body (`apply`/`inject`) plus the injected face, run-state, port and event payload types.
+Compose this package in a web client that also mounts the browser runner and the host runner, and it adds the panel, the tool cards, and the `@` completion. A person then has everything needed to run the lifecycle: approve or decline a model's run request, run, stop, or remove any definition, and watch a package's live state change on the same rows.
 
+### What the panel shows
+
+A `sidebar.footer.action` seat shows a badge counting what runs plus what waits; opening it lists every definition with its run controls. The list is never filtered by session: the current session's rows group first, everyone else's stay listed below. Rows come from the host's current inventory and update whenever an announcement changes what exists. A pending run request whose definition the last read does not cover still gets a row, rendered from the request's own session, label, purpose, and identity. Each row shows two independent facts — what the host runs and what this page has loaded — so a reloaded page offers "load back into this page" before the global stop, while a host-only definition reads plainly running and offers the stop alone. The row also carries this page's last render failure inline, in the same place as a load failure: one is "it never loaded", the other "it loaded and then threw".
+
+### What the tool cards show
+
+The `cordis_define` card is a record: the name and purpose the model wrote, the source it wrote, and whether the definition is running — no switch, no approval, and a pointer to the panel. The `cordis_run` card shows the mode, the plugin, package, and run ids, the outcome, and offers the package's own business view through the `tool.view.cordis` slot when the package registered one. `cordis_stop` and `cordis_undefine` render compact action rows. All cards render from the recorded call and result, so replay shows the same card.
+
+### The @pluginId input source
+
+Typing `@` in the input offers the current session's defined plugins; picking one emits `@pluginId`, which the tool package turns into a pinned reference context for the model.
+
+### Boundaries to plan around
+
+Definitions are process-local: a reloaded page holds nothing until someone runs a package again, and the panel re-reads the inventory on every announcement. Approvals are frame-wide by design, so a person in one tab can approve a run the model asked for while another tab shows the defining session; the first answer wins and the rest converge.

+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design behind the surfaces; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The surfaces are built on one rule: neither keeps run state in component state, because settling a define call moves its card in the chat flow and remounts it. Facts live in observables owned by whoever can close them — the browser runner owns open requests, orchestration outcomes, this page's live set and its render failures, while this package owns the inventory it read and the announcements it folded. The panel is global because a run request blocks the model and can name a definition belonging to a session nobody is looking at; an approval reachable only inside that session's transcript would be unreachable exactly when it blocks the model.

+
+### How the panel stays current
+
+Announcements (`cordis/dynamic-package`, `cordis/dynamic-retract`, `cordis/request-run`, `cordis/request-run-resolved`) trigger an inventory re-read instead of a patch-in-place update, because they carry no labels and a definition can appear or disappear between them. Reads are single-flight so several announcements settling at once cannot multiply the call; a connection reset both discards the in-flight read and frees the slot for a fresh one, so a reconnect never publishes the old host's rows.

 ## Model Experience
 
-Indirectly, through the run and stop verbs these surfaces drive — the browser-side runner's orchestration for a run, and `dynamicCordisRunner.stop` for a stop, the same host verbs the model's `cordis_run` and `cordis_stop` tools reach — so whatever a running definition then contributes is the runner's effect while nothing model-visible originates in this package, which renders logged call/result slices and a host inventory read, adds no prompt content, writes no session event, and deliberately leaves no session-log trace of a person approving, declining, running or stopping anything.

 ## Known Limitations and Deferred Work
 
-- **An open panel does not see registry changes that announce nothing** — `cordis_define`, and an undefine of a definition that was not running, change the registry without a dispatch announcement, so a panel left open across one of them keeps its rows until it is closed and opened again (opening re-reads). A run request is the exception, because it blocks the model: it both renders its own row and triggers a read. Acting on a row the host no longer holds is still honest: the call answers `definition-missing` and the row goes terminal. Polling while open was considered and rejected as the wrong price for it.
-- **A request-only row is answerable but not operable** — it offers approve/decline only, because the run/stop switch needs the registry row the read has yet to deliver. Grouping and copy are unaffected (the ask carries the session, label and reason).
-- **A row disappears for the width of one read if its orchestration outruns it** — the activity's orchestrating arm carries the session but no label, deliberately: a user-initiated run has no ask to take one from, and naming the row after its id would be worse than briefly omitting it. So an approved request whose registry read has not landed leaves no row until it does. In practice the read is triggered when the request arrives, so it has almost always landed by the time anyone answers.
-- **A render failure is this page's own reading, and it arrives too late for the run receipt** — the panel shows the last crash the runner saw HERE, so a package that renders fine in this tab shows nothing even while it crashes in another. It also cannot appear in `cordis_run`'s answer: rendering happens after the run settles, so the model learns about it by asking (`cordis_inspect what:"temporary"`) rather than from the call it already made.
-- **A second page's load failure is invisible to the others** — the host settles a dispatch on the first load report and records later ones without acting, so a page whose browser half failed after another page acknowledged keeps reading as running. That page sees the reason on its own row (the runner reports it); the others cannot.
-- **Any page may answer any request** — approvals are frame-wide by design, so a person in one browser tab can approve a run the model asked for while another tab is in front of the defining session. First answer wins and the rest converge; narrowing who may answer is deferred.
-- **A card whose call head left the event window loses its labels** — the card derives name and purpose from the call arguments, so a session long enough to truncate them leaves it naming its call id. The panel is unaffected: the host inventory carries the labels.
-- **Window truncation degrades the unloaded reading** — the card calls a definition unloaded from a successful `cordis_undefine` in this session's log; a session long enough to push that result out of the window shows the definition as merely not running.

-Cordis 动态插件的浏览器半：一个覆盖整个框架的面板，操作 host 持有的全部定义；以及一张只读的 `cordis_define` 卡片，记录某个会话定义了什么。
+## 概述
 
-**面板做成全局是刻意的。** 模型发起的 `cordis_run` 会在 host 侧阻塞于一次 `cordis/request-run` 往返，而它的答案是**有人按下允许**；并且它可能指向一个当前没人在看的会话里的定义——审批入口若只存在于那个会话的对话流里，就会在它正阻塞模型的时候恰好不可达。所以应答面是一个 `shell.overlay` 条目（本包为 `ui-layout` 补的通用「框架级悬浮席位」，不是自建 React root）：角标计数 = 在跑数 + 待确认数，点开后列出每个定义及其运行控件。列表**同理**从不按会话过滤；当前会话的行置顶成组，其他会话的行仍在下方列出。行来自 host 的全局 `inventory` 调用，并在公告改变「有哪些定义」时**重读而非打补丁**——因为公告不携带名字与用途。而那次读取覆盖不到的开放请求**仍然有行**：直接用运行活动自带的会话、标题、用途与请求标识渲染——`cordis_define` 不广播任何东西，所以在上一次读取之后定义的包，对本页是未知的，而它的请求已经在阻塞模型；此时角标数着一个列表给不出的答案，就等于把模型困死。这样一个请求还会额外触发一次注册表读取，把运行控件补给该行。**归组只读每行上一个已解析好的字段**——有活动的 run 用它自己的会话，其余用注册表行的——而不是按阶段去问不同的 store；活动的**两条臂都带这个字段**，所以应答一个请求不会让它的行跳出人刚刚操作的那一组。组内，阻塞着模型的行排在最前。
+`dsh-client-ui-cordis` 给 web 客户端提供动态 Cordis 包的浏览器面：一个覆盖整个框架的面板，操作 host 持有的全部定义；会话里渲染 `cordis_define`、`cordis_run`、`cordis_stop` 与 `cordis_undefine` 调用的工具卡片；以及一个补全本会话已定义插件的 `@pluginId` 输入源。面板做成全局是刻意的——模型驱动的 run 阻塞在人的审批上，而无论当前在看哪个会话，这个审批都必须可达。本包不撰写任何模型可见的内容：它所操作的一切都来自浏览器 runner 与 host 的清单，卡片渲染的是会话已经记录下的 call 与 result 内容。
 
-**卡片是一份记录。** 它显示模型写下的 name 与 purpose、它写的源码，以及那个定义是否在跑——没有开关、没有审批，只有一句指向面板的指引。素材只取自冻结的 call/result 切片（标签取自 `argsRaw`，host 铸出的 id 取自结果的 `meta.id`），因此 replay 渲染出同一张卡；而有一个读数天生属于卡片：本会话日志里成功的 `cordis_undefine` 是持久且终态的，它**压过 wire**——在 wire 上，retract 公告与一次普通 stop 长得一模一样。
+## 目录
 
-**一行同时读两个互相独立的事实。** 「host 在跑什么」来自 inventory，「**本页**装载了什么」来自 runner 的 live set。每次刷新这两者必然分叉：host 照旧跑着全部，而全新页面什么都没装。host 在跑且本页已装的行，给出全局 stop；host 在跑但本页**没装**的行，先给「装回本页」、再给那个 stop——**两个独立控件**，因为「把浏览器半装到本页」与「为所有页面停掉这个定义」是两件不同的事。**只有 host 半的定义完全不参与这一套**：它没有浏览器半可装，「本页没装」就是它永远的样子，所以它的行如实读作「运行中」，并且只给 stop。未运行时它给出的是一个如实标注的「运行」——本页什么都不会装进来，控件就不这么说——而 run 请求把 `hasClientHalf` 一路带给 runner，正是这一位让它只起 host 半、不去取浏览器半。把这两个事实塌缩成 host 的 `running` 一个，会让刷新后的页面只剩全局 stop，于是文档写明的刷新恢复路径（拉 inventory、把定义装回本页）**没有任何控件可走**。

-**装载成功之后的崩溃，同样属于这一行。** 浏览器半可以装载成功、让 `cordis_run` 答 ok，之后才在 React 渲染它时抛出异常——像误用 `setInterval` 这类错误的教学文案只会落到浏览器控制台，而模型和看着面板的人都不读那里。所以该行会把 runner 记下的、属于本页的最后一次渲染失败就地显示在行内，与装载失败共用同一个位置：一个是「它从来没装上」，另一个是「它装上了、然后抛了」，而一行可以如实地把两者都显示出来。这行文案会点名崩溃的那个座位，并回答随之而来的那个问题——他们的东西还有没有留在屏幕上：遮蔽式座位会让崩溃的条目退场，出厂 UI 随之回来；而 chain 条目会保住自己的位置，它的 UI 可能只是不完整。
+-----
 
-两个面都不把运行态放进组件 state——define 调用结算时卡片会在聊天流里换位置并重挂。事实活在「谁能关闭它、就归谁」的观察量里：浏览器侧 runner 拥有开放请求、编排结果（是它发出 resolve，包括别的页面先应答的情形）与本页的 live set及其渲染失败——它是唯一在监视 `slots.onEntryError` 的一方，也是唯一能把崩溃的条目映射回注册它的那个包的一方——而本包拥有自己读来的清单与折叠过的公告。
+<a id="use-this-package"></a>
+## 使用本包
 
-`/client` 导出面是插件体（`apply`/`inject`）加注入面、运行态、端口与事件载荷类型。
+在同时挂载了浏览器 runner 与 host runner 的 web 客户端中组合本包，它会加上面板、工具卡片与 `@` 补全。人便拥有执行完整生命周期所需的一切：批准或拒绝模型的 run 请求、运行、停止或移除任意定义，并在同一行上看到包的实时状态变化。
 
+### 面板显示什么
+
+一个 `sidebar.footer.action` 席位显示角标，计数在跑数加待确认数；点开后列出每个定义及其运行控件。列表从不按会话过滤：当前会话的行置顶成组，其他会话的行仍在下方列出。行来自 host 的当前清单，并在公告改变「有哪些定义」时更新。上一次读取覆盖不到的待审批 run 请求仍然有行，直接用请求自带的会话、标签、用途与标识渲染。每一行显示两个独立事实——host 在跑什么与本页装载了什么——因此刷新后的页面会先给「装回本页」、再给全局 stop，而纯 host 定义的行如实读作运行中、只给 stop。该行还会把本页最后一次渲染失败就地显示，与装载失败共用同一个位置：一个是「它从来没装上」，另一个是「它装上了、然后抛了」。
+
+### 工具卡片显示什么
+
+`cordis_define` 卡片是一份记录：模型写下的 name 与 purpose、它写的源码，以及该定义是否在跑——没有开关、没有审批，只有一句指向面板的指引。`cordis_run` 卡片显示模式、插件、包与运行标识、结果，并在包注册了业务视图时经 `tool.view.cordis` 槽位提供它。`cordis_stop` 与 `cordis_undefine` 渲染紧凑的动作行。所有卡片都渲染会话记录下的 call 与 result，因此 replay 显示同一张卡。
+
+### @pluginId 输入源
+
+在输入框里键入 `@` 会给出当前会话已定义的插件；选中一个会输出 `@pluginId`，工具包把它变成一条钉住的引用上下文给模型。
+
+### 需要规划的边界
+
+定义以进程为本：刷新后的页面手上什么都没有，直到有人再次运行某个包；面板在每次公告时重读清单。审批按设计是框架级的，所以某个标签页里的人可以批准模型为另一个标签页正在看的会话所发起的 run；首个应答生效，其余收敛。

+<summary>实现细节——点击展开</summary>
+
+本节解释这些界面背后的设计；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+这些界面建立在一个规则之上：两者都不把运行态放进组件 state，因为 define 调用结算时卡片会在聊天流里换位置并重挂。事实活在「谁能关闭它、就归谁」的观察量里——浏览器 runner 拥有开放请求、编排结果、本页的 live set 及其渲染失败，而本包拥有自己读来的清单与折叠过的公告。面板做成全局，是因为 run 请求会阻塞模型、且可能点名一个当前没人在看的会话里的定义；审批入口若只存在于那个会话的对话流里，就会在它正阻塞模型的时候恰好不可达。

+
+### 面板如何保持最新
+
+公告（`cordis/dynamic-package`、`cordis/dynamic-retract`、`cordis/request-run`、`cordis/request-run-resolved`）触发清单重读，而不是就地打补丁——因为公告不携带标签，而定义可能在两次公告之间出现或消失。读取是单飞的，因此多条公告同时结算不会放大调用次数；连接重置既丢弃在途读取、又为新读取腾出位置，所以重连绝不会发布旧 host 的行。

-- **已展开的面板看不到「不广播任何东西」的注册表变化** —— `cordis_define`，以及对一个并未在运行的定义执行 undefine，都会改变注册表却不发出下发公告；因此跨过这类变化时，已展开的面板会保留旧行，直到收起再展开（展开即重读）。run 请求是例外，因为它阻塞模型：它既自己渲染出行，也触发一次读取。对一个 host 已不持有的行动手仍然是诚实的：调用会答 `definition-missing`，该行随即转入终态。「展开期间轮询」评估过，代价不值，已否决。
-- **只有请求、没有清单的行可应答但不可操作** —— 它只提供允许/拒绝，因为 run/stop 开关需要那次读取尚未送达的注册表行。归组与文案不受影响（ask 自带会话、标题与用途）。
-- **若编排跑在读取之前，该行会消失一次读取的时长** —— 活动的 orchestrating 臂带会话但**刻意不带标题**：用户自发的 run 根本不存在可取标题的 ask，而拿 id 当名字比短暂缺行更难看。所以一个已批准、但注册表读取尚未落地的请求，在读取落地前没有行。实践中这次读取在请求**到达时**就已触发，所以等到有人应答时它几乎总已落地。
-- **渲染失败是本页自己的读数，而且它来得太晚、赶不上 run 的回执** —— 面板显示的是 runner 在**本页**看到的最后一次崩溃，所以一个在本标签页渲染正常的包，即使正在另一个标签页里崩溃，这里也什么都不显示。它同样不可能出现在 `cordis_run` 的答复里：渲染发生在 run 结算之后，所以模型只能靠主动去问（`cordis_inspect what:"temporary"`）才知道，而不是从它已经发出的那次调用里得知。
-- **某一页的装载失败对其他页不可见** —— host 以首个装载回报结算一次 dispatch，更晚的回报只记录不动作；因此在另一页确认之后浏览器半才失败的页面，仍会读作运行中。那一页能在自己的行上看到原因（runner 会报），其他页看不到。
-- **任何页面都可以应答任何请求** —— 审批按设计是框架级的，所以某个标签页里的人可以批准模型为另一个标签页正在看的会话所发起的 run。首个应答生效、其余收敛；收窄「谁有权应答」延后。
-- **call head 掉出事件窗的卡片会丢掉标签** —— 卡片的 name 与 purpose 取自调用参数，会话长到把它们截断时，卡片只能以自己的 call id 自称。面板不受影响：host 清单携带标签。
-- **窗口截断会降级「已卸载」这个读数** —— 卡片凭本会话日志里成功的 `cordis_undefine` 判定已卸载；会话长到把那条结果挤出窗口时，该定义只会显示为未运行。

 # feedback/ — recorded human feedback
 
 English | [中文](README.zh.md)
 
-The feedback family exposes two deliberately separate contracts: an immutable remark in the canonical Session log, and editable feedback attached to one assistant message in a local sidecar. Neither form enters the model conversation.
+## Summary
 
-| Package | Role | ctx key |
-|---|---|---|
-| `command-feedback/` | Trigger-independent `feedback/record` event plus the human-facing `/feedback` producer | — |
-| `message-feedback/` | Lifecycle-bound per-message rating/note sidecar plus Host `messageFeedback.list/put/delete` Remote contract | `messageFeedback` |
+The feedback group collects human opinions about the harness's work: users can submit a free-text remark about a whole session, and rate or annotate individual assistant messages. Neither kind of feedback reaches the model — these are signals about the output, never input to it. Users record a session remark with the `/feedback` command; product surfaces read and change per-message ratings through the `messageFeedback` service. The two packages are independent: session remarks and per-message ratings do not interact. This page maps the group; the package READMEs and the [feedback subsystem page](../../docs/subsystems/feedback.md) own the per-package contracts.
 
-A command feedback remark is log-only: it never enters model context or derived history. When mounted, [`dsh-session-telemetry-otel`](../session/session-telemetry-otel) observes `feedback/record` to release a pending telemetry prefix or warn that disabled telemetry leaves the feedback local; capture itself remains independent of that policy.
+## Table of Contents
 
-Message feedback is not a Session event or projection. It remains in the storage-domain sidecar and causes no telemetry handoff. The Host Remote contract ships with the service; the client Remote aggregate mount and UI consumer are separately owned and deferred.

+## Packages
+
+| Package | Role |
+|---|---|
+| [`command-feedback`](command-feedback/README.md) | A `/feedback` command that records a free-text session remark with one command, without a model turn |
+| [`message-feedback`](message-feedback/README.md) | Per-message ratings and notes, served to product surfaces through the `messageFeedback` service |
+
+Session remarks are a one-way signal: recording one is safe at any point in a conversation and never changes what the model sees. With a feedback-gated sharing policy, recording a session remark is what releases the session for sharing.
+
+Per-message ratings and notes are stored with the session, survive restarts, and never appear in model history or telemetry.

 [English](README.md) | 中文

+feedback 组收集用户对 harness 工作成果的意见：用户可以提交一条关于整个会话的自由文本评价，也可以对单条 assistant 消息评分或加备注。两类反馈都不会到达模型——它们是关于输出的信号，绝不是输入。用户通过 `/feedback` 命令记录会话评价；产品界面通过 `messageFeedback` 服务读取和修改逐消息评分。两个包相互独立：会话评价与逐消息评分互不影响。本页是组的映射；包 README 与[反馈子系统页](../../docs/subsystems/feedback.zh.md)负责各自的包级约定。
 
-command feedback 评价仅写入日志：它绝不会进入模型上下文或派生历史。挂载后，[`dsh-session-telemetry-otel`](../session/session-telemetry-otel) 会观察 `feedback/record`，以释放待处理的遥测前缀，或在遥测已禁用时警告反馈将留在本地；采集本身与该策略相互独立。
+## 目录
 
-message feedback 不是 Session 事件或投影。它只保留在 storage-domain 伴随记录中，不触发任何遥测交接。服务随附 Host Remote 契约；客户端 Remote 聚合挂载与 UI 消费方由各自边界负责，并保持延后。

 # @deepseek-ai/dsh-command-feedback
 
 English | [中文](README.zh.md)
 
-Trigger-independent session feedback plus human-facing `/feedback` capture. The package exports `recordFeedback(session, text)`, which appends one log-only `feedback/record` event. Its plugin registers one global command through [`ctx.commands`](../../interaction/commands/README.md), so every composed command adapter discovers it; the shipped Web client executes it without a model turn.
+## Summary
 
-## Command contract
+`dsh-command-feedback` lets a user tell the harness what they think of a session: type `/feedback` plus a remark, and the remark is recorded and acknowledged. Recording is immediate and never starts model work, so it is safe at any point in a conversation — the model neither sees the remark nor is interrupted by it. The acknowledgement names the session and the anonymous user, and reports how the session is shared under the deployment's telemetry policy. The command ships with the Web client and needs no configuration; headless, ACP, and JSON-RPC entry points do not provide slash commands and cannot run it.

+## Use this package
+
+Users can record feedback from the Web client out of the box: the `/feedback` command ships with the standard `dsh` base, needs no configuration, and works in any conversation. A custom app gets the same command by mounting the command registry and this plugin together.
+
+### The `/feedback` command
+
+Type `/feedback` followed by your remark and send it. A successful entry is acknowledged with the receiving session id, the anonymous user id, and the session-sharing policy:
 
 | Input | Result |
 |---|---|
-| `/feedback <text>` | Append `feedback/record` and acknowledge with `Feedback recorded for session {sessionId}`, `Anonymous user: {userId}`, plus the session-sharing disclosure. |
-| `/feedback` | Return a direct usage error. Whitespace-only input is treated as empty. |
+| `/feedback the diff view is unreadable` | Record the remark and acknowledge: `Feedback recorded for session {sessionId}`, `Anonymous user: {userId}`, plus the sharing disclosure. |
+| `/feedback` | A usage error: `Feedback text is required. Usage: /feedback <text>`. Whitespace-only input counts as empty. |
 
-Surrounding whitespace is discarded, but feedback is otherwise unparsed: no truncation, case folding, or control words. Text that looks like another command, such as `/feedback /plan felt slow`, is feedback content. Repeated commands each produce their own event; nothing is replaced or merged.
+Surrounding whitespace is trimmed, but the remark is otherwise kept exactly as typed: no truncation, case folding, or command parsing — `/feedback /plan felt slow` records that literal text. Each command records its own entry; nothing is merged or replaced.
 
-## Session-sharing disclosure
+### The sharing disclosure
 
-The acknowledgement names the receiving session id and reports how that session is shared, read from the mounted [`telemetry`](../../session/session-telemetry/README.md) service through the plugin context (`ctx.get('telemetry')`, never a declared injection). The disclosure is one sentence chosen from the backend's [`SessionTelemetrySharingStatus`](../../session/session-telemetry/README.md):
+The acknowledgement also states how the session is shared under the deployment's telemetry policy:
 
 | Disclosed status | Acknowledgement sentence |
 |---|---|
 | `full` | `Session sharing is enabled.` |
 | `feedback-only` | `Session sharing is feedback-gated; recording feedback releases the session prefix for sharing.` |
 | `disabled` | `Session sharing is disabled.` |
-| no service | `Session sharing is not configured.` |
+| no telemetry service | `Session sharing is not configured.` |
 
-The disclosure states the deployment's current sharing policy only; it never promises delivery or retention. With `full` or `feedback-only`, records are handed to the backend's non-blocking enqueue and the SDK owns batching, retry, and loss policy, so the sentence claims nothing about what reached a collector; `disabled` claims nothing about future reconfiguration. The disclosure adds no event and never enters the model surface.
+The sentence reports the current policy only; it never claims the feedback or the session was delivered anywhere. The disclosure records nothing itself and never reaches the model.
 
-## What this plugin does and does not do
+### Recording feedback from your own UI
 
-`recordFeedback(session, text)` is the command-independent write path. It rejects empty normalized text and appends `feedback/record { text }`; a different UI, hook, or host integration can call it without constructing a slash command. The `/feedback` handler uses that producer and starts no model work. The optional [`dsh-session-telemetry-otel`](../../session/session-telemetry-otel) consumer observes the event without changing its capture contract.
-
-The feedback text appears in exactly one durable payload: `feedback/record`. [`dsh-commands`](../../interaction/commands/README.md) still appends its generic `command/run` / `command/done` pairing, but this definition sets `recordInput: false`, so `command/run` omits `args`; the paired `command/done` carries only the outcome. All three events are log-only and absent from the ordered surface, `deriveMessages()`, and model requests. These appends start persistence's ordinary eager drain, but neither producer forces `session/flush`, so acknowledgement means the feedback is in the log, not that it has reached disk. The acknowledgement identifies both the receiving session and the [shared anonymous user](../../identity/anonymous-user-id/); the first accepted feedback for a harness home can create `$DSH_HOME/.anonymous-user-id`. Rejected empty input leaves only the command pairing settled as `kind: 'error'`, with no `feedback/record` and no user-id lookup.
-
-The event is authoritative rather than the command record because feedback may arrive through a trigger other than `/feedback`. Keeping the payload out of `command/run` avoids two records carrying the same text.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+### Design concept
+
+The remark is one append-only fact in the session log, owned by the event rather than by the command that produced it: feedback can arrive from any trigger, so the fact must not depend on the slash command. The command keeps its own bookkeeping payload-free, so the remark text exists in exactly one place in the log, and the event never surfaces to the model. The sharing disclosure reads the optional telemetry service through the plugin context, so the command still works when no backend is mounted, and its sentence set mirrors the telemetry status union so an unknown status fails closed.
+
+### How a remark is recorded
+
+The producer trims the text, rejects empty input, and writes one event into the session log; the `/feedback` handler is a thin wrapper over that same producer and starts no model work. The write is eager but not flushed: the acknowledgement means the entry reached the log, not the disk. The first accepted remark for a harness home also mints the anonymous user id the acknowledgement reports. The exact producer contract and event payload live in [`src/index.ts`](src/index.ts).

+## 使用本包
+
+用户可以直接在 Web 客户端中记录反馈：`/feedback` 命令随标准 `dsh` 基础组合交付，无需配置，可在任何对话中使用。自定义应用只需把命令注册表与本插件组合在一起，即可获得同样的命令。
+
+### `/feedback` 命令
+
+输入 `/feedback` 加你的评价并发送。成功时会以接收会话 id、匿名用户 id 与共享策略确认：
 
 | 输入 | 结果 |
 |---|---|
-| `/feedback <text>` | 追加 `feedback/record`，并以 `Feedback recorded for session {sessionId}`、`Anonymous user: {userId}` 加会话共享披露确认。 |
-| `/feedback` | 返回一个直接用法错误。仅含空白的输入视为空输入。 |
+| `/feedback the diff view is unreadable` | 记录评价并确认：`Feedback recorded for session {sessionId}`、`Anonymous user: {userId}`，外加共享披露。 |
+| `/feedback` | 用法错误：`Feedback text is required. Usage: /feedback <text>`。仅含空白的输入视为空输入。 |
 
-前后空白会被丢弃，但除此之外，反馈内容不会被解析：不进行截断或大小写折叠，也不识别控制词。看起来像另一个命令的文本（例如 `/feedback /plan felt slow`）就是反馈内容。重复执行命令时，每次都会产生一个事件；不会发生替换或合并。
+前后空白会被去除，但除此之外，评价会按输入原样保留：不进行截断、大小写折叠或命令解析——`/feedback /plan felt slow` 记录的就是这段字面文本。每次执行命令都会记录自己的条目；不会发生合并或替换。
 
-## 会话共享披露
+### 共享披露
 
-确认文本会点名接收会话的 id，并报告该会话如何被共享；该信息通过插件上下文（`ctx.get('telemetry')`，绝不是声明的注入）从已挂载的 [`telemetry`](../../session/session-telemetry/README.zh.md) 服务读取。披露是依据后端 [`SessionTelemetrySharingStatus`](../../session/session-telemetry/README.zh.md) 选择的一句话：
+确认文本还会说明部署的遥测策略下会话如何被共享：
 
 | 披露的状态 | 确认文本中的句子 |
 |---|---|
 | `full` | `Session sharing is enabled.` |
 | `feedback-only` | `Session sharing is feedback-gated; recording feedback releases the session prefix for sharing.` |
 | `disabled` | `Session sharing is disabled.` |
-| 无服务 | `Session sharing is not configured.` |
+| 无遥测服务 | `Session sharing is not configured.` |
 
-披露只陈述部署当前的共享策略，绝不承诺投递或留存：在 `full` 或 `feedback-only` 下，记录被交给后端的非阻塞入队，批处理、重试与丢失策略归 SDK 负责，因此句子不声称任何内容已到达采集端；`disabled` 也不声称未来不会重新配置。披露不新增任何事件，也绝不会进入模型 surface。
+句子只报告当前策略，绝不声称反馈或会话已投递到任何地方。披露本身不记录任何内容，也绝不会到达模型。
 
-## 本插件做什么、不做什么
+### 从自己的 UI 记录反馈
 
-`recordFeedback(session, text)` 是不依赖命令的写入路径。它拒绝规范化后为空的文本，并追加 `feedback/record { text }`；其他 UI、钩子或 host 集成无需构造斜杠命令即可调用它。`/feedback` 处理器通过该函数写入，且不启动任何模型工作。可选的 [`dsh-session-telemetry-otel`](../../session/session-telemetry-otel) 消费方会观察该事件，但不改变它的采集约定。
-
-反馈文本只出现在一个持久载荷中：`feedback/record`。[`dsh-commands`](../../interaction/commands/README.zh.md) 仍会追加通用的 `command/run` / `command/done` 配对，但此定义设置了 `recordInput: false`，因此 `command/run` 会省略 `args`；配对的 `command/done` 只携带结果。三个事件都仅写入日志，不出现在有序 surface、`deriveMessages()` 以及模型请求中。这些追加会启动持久化的常规即时排空，但两个生产方都不会强制 `session/flush`，因此确认文本表示反馈已进入日志，而不表示它已经落盘。确认文本同时标明接收反馈的会话和[共享匿名用户](../../identity/anonymous-user-id/)；对于某个 harness home，首次接受反馈时可能创建 `$DSH_HOME/.anonymous-user-id`。被拒绝的空输入只会留下以 `kind: 'error'` 结算的命令配对，不会产生 `feedback/record`，也不会查找用户 id。
-
-权威记录是该事件，而不是命令记录，因为反馈可能来自 `/feedback` 之外的触发方式。让载荷不进入 `command/run`，可避免两条记录携带相同文本。

+### 设计理念
+
+评价是会话日志中一个仅追加的事实，由事件而非产生它的命令拥有：反馈可能来自任何触发方式，因此事实绝不能依赖斜杠命令。命令自身的簿记不携带载荷，所以评价文本在日志中只存在于一个地方，且该事件绝不会浮出到模型。共享披露通过插件上下文读取可选的遥测服务，因此未挂载后端时命令仍可用；句子集镜像遥测状态 union，未知状态会快速失败。

+### 评价如何被记录
+
+生产方去除文本空白、拒绝空输入，并向会话日志写入一个事件；`/feedback` 处理器是该生产方的薄包装，不启动任何模型工作。写入是即时但未 flush 的：确认文本表示条目已到达日志，而不是已落盘。某个 harness home 首次接受的评价还会铸造确认文本所报告的匿名用户 id。精确的生产方约定与事件载荷见 [`src/index.ts`](src/index.ts)。

-Host-owned editable feedback for one finalized assistant message. The package registers `ctx.messageFeedback`, persists one lifecycle-bound sidecar row per Session in storage-domain, and publishes the Host `messageFeedback.list`, `messageFeedback.put`, and `messageFeedback.delete` unary Remote contract. It is separate from the immutable Session-level `feedback/record` event and performs no telemetry handoff. The [message-feedback sidecar Agent Note](../../../.agents/notes/implemented/architecture/2026-08-10-message-feedback-sidecar.md) owns the design boundary.
+## Summary
 
-Public request, value, version, and failure types are exported from the package root and `@deepseek-ai/dsh-message-feedback/types`; [`src/types.ts`](src/types.ts) is their source.
+`dsh-message-feedback` lets product surfaces offer per-message feedback: a user marks an assistant message positive or negative and can attach a short note, and the rating stays with that message. Ratings are stored with the session, survive restarts, and never enter model history or telemetry. Product surfaces read, create, and change ratings through the `messageFeedback` service, whose `list`, `put`, and `delete` operations are the whole surface. The one deployment setting is the maximum note length (`maxNoteBytes`), which the Web bundle sets to 8192. Browser controls live in a separate client package; this package provides the service itself.

-Notes must contain at least one non-whitespace character, but accepted text is stored verbatim rather than trimmed. Omitting `note` means the desired value has no note, so a version-matched material `put` clears an existing note. Note validation precedes Session lookup and can therefore return `note-blank` or `note-too-large` for a missing Session without touching persistence.

A material update preserves `createdAt`, replaces `version`, and keeps `updatedAt` from moving backward. `list` returns fresh immutable snapshots in first-creation order; updating an item retains its place, while deleting and later recreating it appends a new item.
+Callers use three operations to read and change feedback for a session:
 
-Each stored row carries the inspected Session header identity `{createdAt, cwd}`. A mismatch is treated as absence: `list` returns an empty `items` array, `delete` returns the absent postcondition, and `put` may replace the stale row with one bound to the current identity. This fences a reused `SessionId` when its header identity differs. Forks use a distinct Session identity and receive no feedback-row copy.
-
-`SessionPersistence.inspect()` supplies a cold-safe observation without publishing or resuming an Agent and without committing cold repair. For a Session without a live owner, `listSnapshots()` first decides definite absence; an `inspect()` failure for a catalogued Session remains an infrastructure failure rather than being guessed into `session-not-found`. `put` accepts only a non-empty, append-origin `assistant/message` with the requested `MessageId`; replacement-origin messages, empty usage-only assistant records, and non-assistant records return `target-not-found`.
-
-After initial validation, `put` establishes a durability barrier before writing the sidecar. A matching live Session commits through the canonical `ctx.sessions.flush` checkpoint, then both live and cold paths are physically read from sequence zero through `SessionPersistence.readFrom`. The resulting observation's header identity and target are validated again. A missing flush participant, changed identity, vanished target, or physical-read failure prevents the sidecar commit, so durable feedback never precedes the durable target message.
-
-Message feedback is not Session-log content or a Session projection. It emits no `feedback/record` event, does not enter model history, and does not trigger `FEEDBACK_ONLY` telemetry release.
-
-## Service and Host Remote contract
-
-The same three `MessageFeedbackService` methods are published by `TypertRemoteService` and `@Remote`; the Host endpoint names are `messageFeedback.list`, `messageFeedback.put`, and `messageFeedback.delete`. Every method returns a discriminated business union: `{ ok: true, value }` or `{ ok: false, error }`. Operational storage, corruption, or missing-durability-listener failures reject instead of being mislabeled as business errors.
-
-| Method | Request | Success `value` | Rejected `error.code` |
+| Operation | Request | Success | Rejected when |
 |---|---|---|---|
-| `list` | `MessageFeedbackListRequest { sessionId }` | `MessageFeedbackListValue { items }` | `session-not-found` |
-| `put` | `MessageFeedbackPutRequest { sessionId, messageId, rating, note?, ifVersion }` | committed `MessageFeedbackItem` | `session-not-found`, `target-not-found`, `version-conflict`, `note-blank`, `note-too-large` |
-| `delete` | `MessageFeedbackDeleteRequest { sessionId, messageId, ifVersion }` | `MessageFeedbackDeleteValue { absent: true }` | `session-not-found`, `version-conflict` |
+| `list` | the session id | the current ratings and notes, in creation order | the session is not found |
+| `put` | session, message, rating, optional note, expected version | the stored rating and note | session not found, message is not a valid target, version conflict, blank or oversized note |
+| `delete` | session, message, expected version | the rating is absent | session not found, version conflict |
 
-`MessageFeedbackVersionConflict` returns the authoritative `current` item, or `null` when no item exists. This lets a caller reconcile the current rating, note, and version without a second `list` request. `MessageFeedbackNoteTooLarge` returns both `maxBytes` and `actualBytes`. The Client Remote aggregate does not mount the generated client contribution yet; Host callers can use the service/Remote contract without that client assembly.
+Every change must be based on the version the service returned for that rating: a change based on an older version is rejected with `version-conflict`, and the reply carries the current rating so the caller can see what changed without another read. Deleting a rating that is already absent succeeds, and concurrent changes to different messages do not conflict. An omitted note clears an existing note.
 
-## Compare-and-set and idempotency
+### What you can rate
 
-`ifVersion: null` requests creation only; every request for an existing item requires its exact current version, including a no-op whose desired value already matches. The check is per message rather than per Session, so changing one item does not conflict with another. Every material create or update assigns a fresh opaque UUID token, preventing stale writes from crossing an ABA value cycle.
+A rating attaches to one finalized assistant message: the message must exist and be an assistant message that was sent. User messages, empty assistant placeholders, and replaced messages are not valid targets and are rejected with `target-not-found`. Once recorded, the rating and note stay with that message and survive restarts; a fork of the session starts with no feedback.
 
-A matching-version no-op returns the already stored item with unchanged version and timestamps. After a lost success response, a retry with the old token receives `version-conflict.current`; the caller can compare that authoritative item with its desired value without an extra read. `delete` ignores `ifVersion` when the item is already absent and always returns the stable `{ absent: true }` postcondition after success.
+### Durability
 
-A per-Session promise queue encloses inspection, durability validation, sidecar read, comparison, and whole-row write. These semantics serialize concurrent mutations through one service instance; storage-domain itself has no cross-process conditional write.
+A rating is committed only after the message it refers to is durably stored, so feedback never points at a message that can be lost. Reading or writing feedback never starts or resumes an agent; the service inspects the persisted session directly.
 
-Plugin disposal closes mutation admission, drains every operation already accepted into the per-Session queues, and only then closes the storage domain. A mutation submitted after disposal begins rejects as a lifecycle failure instead of entering a closing domain.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+### Design concept
+
+The service keeps feedback outside the session log entirely: each session owns one sidecar row in a storage domain, so a rating can never be confused with conversation content, model history, or telemetry. The sidecar is only ever committed after the message it references is durable — the row extends the target log instead of preceding it. Every operation returns a business result that distinguishes a handled failure (missing session, invalid target, stale version, bad note) from an infrastructure failure, which rejects instead of being mislabeled.
+
+### What a sidecar holds
+
+One row per session binds the inspected session identity (`createdAt`, `cwd`) to its feedback items; the identity fences a reused session id, so a row from an earlier lifecycle is invisible and a fork starts with no feedback. Items are immutable values — a change writes a new version of the item, preserving its creation time — and the row schema rejects duplicate message ids and reused versions so lookup stays unambiguous. The exact row schema and validation live in [`src/spec.ts`](src/spec.ts).
+
+### Concurrency
+
+Mutations are optimistic and per message: a caller sends the version it last observed, a stale version is rejected with the authoritative current item so the caller reconciles without another read, and every material change mints a fresh version token so a stale write can never masquerade as current. A per-session queue serializes the whole read-compare-write through one service instance; storage provides no cross-process conditional write, which is the Known Limitation below.
+
+### Durability and target validation
+
+A write is staged, verified, then committed: the target message is flushed through the canonical checkpoint, the physical log prefix is re-read, and only then is the sidecar row written — feedback can never reference a message that is not durable. Cold sessions are inspected without resuming an agent, absence is decided from the persistence catalog rather than guessed, and only a real, sent assistant message is a valid target. The flush and inspect path lives in [`src/index.ts`](src/index.ts).
+
+### Failure modes
+
+The service fails closed: disposal drains in-flight writes before closing the domain, a write submitted after disposal starts is rejected as a lifecycle failure, and invalid configuration or a read before domain initialization fails loudly.
+
+### Source map

-## 数据、生命周期与持久性
+### 读取与修改反馈
 
-`MessageFeedbackItem` 包含 `messageId`、`rating: 'positive' | 'negative'`、可选 `note`、只能做相等比较的 opaque `version`，以及由 Host 分配、以 Unix 毫秒表示的 `createdAt`/`updatedAt` 时间戳。实质更新保留 `createdAt`、替换 `version`，并保证 `updatedAt` 不倒退。`list` 按首次创建顺序返回新的不可变快照；更新条目时保留其位置，删除后再创建则追加为新条目。
+调用方用三个操作读取和修改某个会话的反馈：
 
-每条存储行都携带检查所得 Session header 身份 `{createdAt, cwd}`。不匹配按不存在处理：`list` 返回空 `items` 数组，`delete` 返回已不存在的后置条件，`put` 可以用绑定当前身份的新行替换陈旧行。这会在复用的 `SessionId` 具有不同 header 身份时形成隔离。fork 使用独立的 Session 身份，不复制反馈伴随记录。
-
-`SessionPersistence.inspect()` 提供 cold-safe 观测，不发布或恢复 Agent，也不提交 cold repair。对于没有 live owner 的 Session，系统先用 `listSnapshots()` 判定明确不存在；已进入目录的 Session 若 `inspect()` 失败，仍属于基础设施故障，不会被猜测成 `session-not-found`。`put` 只接受具有指定 `MessageId` 的非空、append-origin `assistant/message`；replacement-origin 消息、仅承载 usage 的空 assistant 记录与非 assistant 记录都返回 `target-not-found`。
-
-初步校验后，`put` 在写入伴随记录前建立 durability barrier。身份匹配的 live Session 先通过权威 `ctx.sessions.flush` checkpoint 提交，随后 live 与 cold 路径都会通过 `SessionPersistence.readFrom` 从序列零做物理复读。之后再次校验所得观测的 header 身份与目标。缺少 flush 参与方、身份变化、目标消失或物理读取失败都会阻止伴随记录提交，因此持久反馈绝不会先于其持久目标消息。
-
-message feedback 不是 Session 日志内容或 Session 投影。它不发出 `feedback/record` 事件，不进入模型历史，也不触发 `FEEDBACK_ONLY` 遥测释放。
-
-## 服务与 Host Remote 契约
-
-`TypertRemoteService` 与 `@Remote` 将 `MessageFeedbackService` 的同三个方法发布出去；Host endpoint 名称为 `messageFeedback.list`、`messageFeedback.put` 与 `messageFeedback.delete`。每个方法都返回判别式业务 union：`{ ok: true, value }` 或 `{ ok: false, error }`。存储、损坏或缺少 durability listener 等操作故障会产生 reject，不会被误标为业务错误。
-
-| 方法 | 请求 | 成功 `value` | 拒绝的 `error.code` |
+| 操作 | 请求 | 成功 | 拒绝时机 |
 |---|---|---|---|
-| `list` | `MessageFeedbackListRequest { sessionId }` | `MessageFeedbackListValue { items }` | `session-not-found` |
-| `put` | `MessageFeedbackPutRequest { sessionId, messageId, rating, note?, ifVersion }` | 已提交的 `MessageFeedbackItem` | `session-not-found`、`target-not-found`、`version-conflict`、`note-blank`、`note-too-large` |
-| `delete` | `MessageFeedbackDeleteRequest { sessionId, messageId, ifVersion }` | `MessageFeedbackDeleteValue { absent: true }` | `session-not-found`、`version-conflict` |
+| `list` | 会话 id | 当前的评分与备注，按创建顺序 | 会话不存在 |
+| `put` | 会话、消息、评分、可选备注、期望的 version | 已存储的评分与备注 | 会话不存在、消息不是有效目标、version 冲突、备注空白或超长 |
+| `delete` | 会话、消息、期望的 version | 评分已不存在 | 会话不存在、version 冲突 |
 
-`MessageFeedbackVersionConflict` 返回权威 `current` 条目；条目不存在时为 `null`。调用方无需额外执行 `list`，即可协调当前 rating、note 与 version。`MessageFeedbackNoteTooLarge` 同时返回 `maxBytes` 与 `actualBytes`。客户端 Remote 聚合尚未挂载生成的客户端 contribution；Host 调用方无需该客户端组装即可使用 service/Remote 契约。
+每次修改都必须基于服务为该项评分返回的 version：基于更旧 version 的修改会以 `version-conflict` 拒绝，且回复携带当前评分，调用方无需再次读取即可看到变化。删除一条已经不存在的评分会成功；对不同消息的并发修改互不冲突。省略 `note` 会清除已有备注。
 
-## Compare-and-set 与幂等性
+### 可以对什么评分
 
-`ifVersion: null` 表示仅当条目不存在时才创建；已有条目的每次请求都必须与其当前 version 完全一致，即使目标值已经相同、不会产生实质更新。检查按消息而非按 Session 进行，因此修改一个条目不会与另一个条目冲突。每次实质创建或更新都会分配新的 opaque UUID token，防止陈旧写入穿过 ABA 值循环。
+评分绑定一条已完成的 assistant 消息：消息必须存在，并且是发送过的 assistant 消息。用户消息、空的 assistant 占位与已被替换的消息都不是有效目标，会以 `target-not-found` 拒绝。评分与备注一旦记录就与该消息绑定并跨重启保留；会话的 fork 从没有反馈开始。
 
-携带匹配 version 的无变化请求会返回已存条目，version 与时间戳均不变。成功响应丢失后，使用旧 token 重试会得到 `version-conflict.current`；调用方无需额外读取，即可把权威当前值与目标值比较。条目已不存在时，`delete` 忽略 `ifVersion`；成功后始终返回稳定的 `{ absent: true }` 后置条件。
+### 持久性
 
-按 Session 划分的 promise 队列覆盖检查、持久性校验、伴随记录读取、比较与整行写入。这些语义会串行化经由同一服务实例的并发变更；storage-domain 自身没有跨进程条件写。
+只有当评分所指的消息已被持久存储后，评分才会提交，因此反馈绝不会指向可能丢失的消息。读取或写入反馈绝不会启动或恢复 agent；服务直接检查已持久化的会话。
 
-Plugin disposal 会先关闭变更接纳，排空已进入各个 Session 队列的所有操作，然后才关闭 storage domain。disposal 开始后提交的变更会以生命周期故障拒绝，不会进入正在关闭的 domain。

+## 理解实现
+
+<details>
+<summary>实现细节——点击展开</summary>
+
+### 设计理念
+
+服务把反馈完全放在会话日志之外：每个会话在存储域中拥有一条伴随记录行，因此评分绝不会与对话内容、模型历史或遥测混淆。伴随记录只在所引用消息已持久之后提交——该行是目标日志的延伸，而不是先于它。每个操作都返回业务结果，把已处理的失败（会话缺失、目标无效、版本陈旧、备注不合格）与基础设施故障区分开，后者会 reject 而非被误标。
+
+### 伴随记录里有什么
+
+每个会话一行，把检查所得的会话身份（`createdAt`、`cwd`）与其反馈条目绑定；该身份隔离复用的会话 id，因此更早生命周期的行不可见，fork 也从无反馈开始。条目是不可变值——修改会写入条目新版本并保留其创建时间——行 schema 拒绝重复消息 id 与复用的版本，保证查找无歧义。精确的行 schema 与校验见 [`src/spec.ts`](src/spec.ts)。
+
+### 并发
+
+修改是乐观的、按消息进行的：调用方发送其最后观察到的 version，陈旧的 version 会连同权威当前条目一起被拒绝，调用方无需再次读取即可协调；每次实质修改都会铸造新的 version token，陈旧写入绝不会被误认为当前。按 Session 的队列把整个读-比较-写串行化在一个服务实例内；存储不提供跨进程条件写，这正是下文「已知限制」。
+
+### 持久性与目标校验
+
+写入按「暂存—校验—提交」进行：目标消息先通过权威 checkpoint flush，再物理重读日志前缀，之后才写入伴随记录行——反馈绝不会引用尚未持久的消息。冷会话在不恢复 agent 的情况下被检查，缺失依据持久化目录判定而非猜测，只有真实发送过的 assistant 消息才是有效目标。flush 与检查路径见 [`src/index.ts`](src/index.ts)。
+
+### 故障模式
+
+服务失败时保持封闭：disposal 先排空在途写入再关闭域，disposal 开始后提交的写入会以生命周期故障拒绝，无效配置或域初始化前的读取都会明确失败。

-The filesystem stack: a provider contract (execution-world paths, bounded text IO, and atomic mutation with an optional version guard), a local implementation, a policy gate plugin (observed-state + read-before-edit + version-guarded write/edit), the model-facing file tools + executor, and the ripgrep-backed discovery tools. All **product** packages.
+## Summary
+
+The `fs/` group gives agents durable, policy-governed access to files: the `ctx.fs` service contract in `fs/`, the host-filesystem and sandbox-enforcing backends in `fs-local/` and `fs-sandbox/`, the read-before-edit policy in `fs-observation-policy/`, and the model-facing tools in `tool-fs/` (`read`, `read_image`, `write`, `edit`) and `tool-fs-search/` (`glob`, `grep`). A deployment mounts one backend, loads the policy for freshness-guarded mutations, and registers the tool packages the model should see; backends swap without touching the tools or the policy. File I/O takes no timeout by design: a deadline would kill work the OS still finishes, so cancellation is a best-effort signal at syscall boundaries.

+## Packages
+
+Seven packages plus the remote sibling `fs-e2b` play the filesystem roles; the subsystem reference owns the exhaustive contracts and the error taxonomy.
 
 | Package | Role | ctx key |
 |---|---|---|
-| `fs/` | Service Definition: canonical process paths/file URIs/containment, text IO, and atomic mutation primitives; owns the `fs/*` policy events | `ctx.fs` |
-| `fs-local/` | Local-filesystem `FileSystem` implementation | (registers `ctx.fs`) |
-| [`e2b/fs-e2b`](../e2b/fs-e2b/README.md) | E2B-backed `FileSystem` implementation sharing the remote runtime owned by `ctx.e2b` | (registers `ctx.fs`) |
-| `fs-sandbox/` | Sandbox-enforcing `FileSystem`: extends `fs-local` and fences write/edit by the per-call mode + workspace root policy (read-only denies, workspace-write contains to the session workspace + temp roots), reads pass through | (registers `ctx.fs`) |
-| `fs-observation-policy/` | Policy gate plugin: observed-state + read-before-edit + version-guarded write/edit, via the `fs/*` event gate | (no service — `fs/*` listeners) |
-| `tool-fs/` | Model-facing `read`/`write`/`edit` tools AND the executor (reads via `ctx.fs`, owns read windowing, dispatches `fs/*`); preserves filesystem semantics for session-cwd-relative paths and advertises sandbox escalation fields when the mounted `ctx.fs` confines | (registers on `ctx.tools`) |
-| `tool-fs-search/` | Model-facing `glob`/`grep` discovery tools backed by the packaged `@vscode/ripgrep` binary spawned through `ctx.subprocess`, NOT by `ctx.fs` provider methods | (registers on `ctx.tools`) |
+| [`fs/`](fs/README.md) | `ctx.fs` service contract: execution-world paths, bounded text I/O, and atomic mutations with an optional version guard | `ctx.fs` |
+| [`fs-local/`](fs-local/README.md) | Host-filesystem backend: reads, writes, and edits real files on the local machine | registers on `ctx.fs` |
+| [`fs-sandbox/`](fs-sandbox/README.md) | Sandbox-enforcing backend: fences writes and edits by the per-call sandbox mode while reads pass through | registers on `ctx.fs` |
+| [`e2b/fs-e2b`](../e2b/fs-e2b/README.md) | E2B-backed backend: file state lives in the remote execution world shared with the E2B subprocess provider | registers on `ctx.fs` |
+| [`fs-observation-policy/`](fs-observation-policy/README.md) | Read-before-edit policy: records observed presence or absence and guards write/edit through the `fs/*` events | `fs/*` listeners |
+| [`tool-fs/`](tool-fs/README.md) | Model-facing `read`, `read_image`, `write`, and `edit` tools plus their executor | registers on `ctx.tools` |
+| [`tool-fs-search/`](tool-fs-search/README.md) | Model-facing `glob` and `grep` discovery tools backed by the packaged ripgrep binary | registers on `ctx.tools` |
+| [`tool-str-replace-editor/`](tool-str-replace-editor/README.md) | Standalone `str_replace_editor` tool: `view`, `create`, `str_replace`, and `insert` over `ctx.fs` | registers on `ctx.tools` |
 
-The Service Definition lives at `fs/fs/`. A sandboxed, remote, or project-scoped filesystem backend can replace `fs-local` without touching the Service Definition, policy gate, or model-facing tool schemas: `fs-sandbox` provides an in-process path fence over the shared sandbox mode ([decision](../../.agents/notes/implemented/feature/2026-07-14-cross-family-fs-sandbox.md)), while `fs-e2b` places file state in the remote execution world shared with the E2B subprocess provider ([decision](../../.agents/notes/implemented/architecture/2026-07-28-portable-execution-world-consumers.md)). The policy (`fs-observation-policy/`) is a plugin that participates only through the `fs/*` event gate, not a service the tool injects — so dropping it gracefully loses the policy and leaves the unconstrained bare provider rather than breaking the tool. A deployment that loads `tool-fs/` is expected to also load it. The mode fence and the read-before-edit gate are orthogonal and compose. Discovery (`tool-fs-search/`) deliberately does NOT extend the provider contract: search is a process-backed `rg` workflow (the packaged `@vscode/ripgrep` binary spawned through `ctx.subprocess`), so filesystem backends stay free of a universal search contract; its tools register unconditionally, and its results are follow-up-readable when the search workdir and the `read` root are the same workspace (the co-located deployment its README documents).
+The policy is a plugin, not a service the tools inject: removing it leaves the bare provider's unconditional mutation behavior instead of breaking the tools. The mode fence in `fs-sandbox` and the read-before-edit gate compose. `tool-fs-search` deliberately does not extend the provider contract — search is a process-backed ripgrep workflow, so filesystem backends stay free of a universal search API.
 
-## No timeouts on file IO
+-----
 
-`read`/`write`/`edit` take **no** `timeoutMs` and the provider contract arms no deadline: file IO here runs untimed because a deadline would kill work the OS will still finish — see [the filesystem subsystem page](../../docs/subsystems/filesystem.md). Cancellation still propagates through the tool-execution signal for best-effort abort at syscall boundaries.

-文件系统栈包括：提供方约定（执行世界路径、有界文本 I/O 与带可选版本防护的原子变更）、本地实现、政策门禁插件（已观察状态、编辑前读取、版本防护的写入/编辑）、面向模型的文件工具与执行器，以及基于 ripgrep 的发现工具。全部都是**产品**包。
+## 概述
 
-| 包 | 角色 | ctx 键 |
+`fs/` 组为 agent（智能体）提供持久、受策略约束的文件访问：`fs/` 定义 `ctx.fs` 服务约定，`fs-local/` 与 `fs-sandbox/` 提供宿主文件系统与沙箱强制后端，`fs-observation-policy/` 提供编辑前读取策略，`tool-fs/`（`read`、`read_image`、`write`、`edit`）与 `tool-fs-search/`（`glob`、`grep`）提供面向模型的工具。部署挂载一个后端，加载策略以获得新鲜度防护的变更，并注册模型应看到的工具包；后端可以更换，无需改动工具或策略。文件 I/O 有意不设超时：deadline 只会杀掉操作系统仍会完成的工作，因此取消只是系统调用边界的尽力而为信号。

+## 包
+
+七个包加上远程同级 `fs-e2b` 承担文件系统角色；子系统参考文档拥有穷尽式约定与错误分类体系。
+
+| 包 | 职责 | ctx 键 |
 |---|---|---|
-| `fs/` | Service Definition：规范化进程路径、文件 URI 与包含关系、文本 I/O 和原子变更原语；拥有 `fs/*` 政策事件 | `ctx.fs` |
-| `fs-local/` | 本地文件系统 `FileSystem` 实现 | （注册 `ctx.fs`） |
-| [`e2b/fs-e2b`](../e2b/fs-e2b/README.zh.md) | 以 E2B 为后端的 `FileSystem` 实现，共享由 `ctx.e2b` 拥有的远程运行时 | （注册 `ctx.fs`） |
-| `fs-sandbox/` | 强制沙箱的 `FileSystem`：扩展 `fs-local`，并按每次调用的模式与工作区根政策约束写入/编辑（只读模式拒绝，工作区写入模式限制在会话工作区与临时根目录内）；读取直接通过 | （注册 `ctx.fs`） |
-| `fs-observation-policy/` | 政策门禁插件：通过 `fs/*` 事件门禁提供已观察状态、编辑前读取和版本防护的写入/编辑 | （无服务，仅有 `fs/*` 监听器） |
-| `tool-fs/` | 面向模型的 `read`/`write`/`edit` 工具以及执行器（通过 `ctx.fs` 读取，拥有读取窗口逻辑，分派 `fs/*`）；为会话 cwd 相对路径保留文件系统语义，并在已挂载的 `ctx.fs` 实施约束时声明沙箱升级字段 | （注册到 `ctx.tools`） |
-| `tool-fs-search/` | 面向模型的 `glob`/`grep` 发现工具，由经 `ctx.subprocess` spawn 的打包 `@vscode/ripgrep` 二进制文件支持，而不是使用 `ctx.fs` 提供方方法 | （注册到 `ctx.tools`） |
+| [`fs/`](fs/README.zh.md) | `ctx.fs` 服务约定：执行世界路径、有界文本 I/O，以及带可选版本防护的原子变更 | `ctx.fs` |
+| [`fs-local/`](fs-local/README.zh.md) | 宿主文件系统后端：读取、写入并编辑本机上的真实文件 | 注册到 `ctx.fs` |
+| [`fs-sandbox/`](fs-sandbox/README.zh.md) | 沙箱强制后端：按每次调用的沙箱模式约束写入与编辑，读取直接通过 | 注册到 `ctx.fs` |
+| [`e2b/fs-e2b`](../e2b/fs-e2b/README.zh.md) | 以 E2B 为后端：文件状态位于与 E2B 子进程提供方共享的远程执行世界 | 注册到 `ctx.fs` |
+| [`fs-observation-policy/`](fs-observation-policy/README.zh.md) | 编辑前读取策略：记录观测到的存在或缺失，并通过 `fs/*` 事件防护写入/编辑 | `fs/*` 监听器 |
+| [`tool-fs/`](tool-fs/README.zh.md) | 面向模型的 `read`、`read_image`、`write` 与 `edit` 工具及其执行器 | 注册到 `ctx.tools` |
+| [`tool-fs-search/`](tool-fs-search/README.zh.md) | 由打包 ripgrep 二进制支持的面向模型 `glob` 与 `grep` 发现工具 | 注册到 `ctx.tools` |
+| [`tool-str-replace-editor/`](tool-str-replace-editor/README.zh.md) | 独立的 `str_replace_editor` 工具：基于 `ctx.fs` 的 `view`、`create`、`str_replace` 与 `insert` | 注册到 `ctx.tools` |
 
-Service Definition 位于 `fs/fs/`。沙箱化、远程或限定项目作用域的文件系统后端可以替换 `fs-local`，而无需更改 Service Definition、政策门禁或面向模型的工具 schema：`fs-sandbox` 基于共享沙箱模式提供进程内路径围栏（[决策](../../.agents/notes/implemented/feature/2026-07-14-cross-family-fs-sandbox.zh.md)），而 `fs-e2b` 则把文件状态置于与 E2B 子进程提供方共享的远程执行世界中（[决策](../../.agents/notes/implemented/architecture/2026-07-28-portable-execution-world-consumers.zh.md)）。政策（`fs-observation-policy/`）是一个只通过 `fs/*` 事件门禁参与的插件，不是工具注入的服务；因此移除它会平稳失去政策，留下不受约束的裸提供方，而不会破坏工具。加载 `tool-fs/` 的部署也应加载该插件。模式围栏与编辑前读取门禁彼此正交，可以组合。发现（`tool-fs-search/`）有意不扩展提供方约定：搜索是由进程支持的 `rg` 工作流（经 `ctx.subprocess` spawn 的打包 `@vscode/ripgrep` 二进制文件），因此文件系统后端无需承担通用搜索约定；其工具会无条件注册。如果搜索工作目录与 `read` 根目录是同一工作区，结果就能继续读取，这也是其 README 所述的共置部署。
+策略是插件，不是工具注入的服务：移除它只会让工具回到裸提供方的无条件变更行为，而不会破坏工具。`fs-sandbox` 的模式围栏与编辑前读取门禁可以组合。`tool-fs-search` 有意不扩展提供方约定——搜索是由进程支持的 ripgrep 工作流，因此文件系统后端无需承担通用搜索 API。

 # @deepseek-ai/dsh-fs-local
 
 English | [中文](README.zh.md)
 
-The **local-filesystem implementation** of the `ctx.fs` provider contract ([`@deepseek-ai/dsh-fs`](../fs)). Backs the twelve `FileSystem` primitives with the host filesystem; loading it as a plugin populates `ctx.fs`.
+## Summary
 
-```ts ignore-check
-import { LocalFileSystem } from '@deepseek-ai/dsh-fs-local'
+`dsh-fs-local` implements the `ctx.fs` filesystem contract ([`dsh-fs`](../fs/README.md)) on the host filesystem: loading it as a plugin populates `ctx.fs` with real file access — resolve, read, list, atomic write, and literal edit against the local machine's files. Relative paths resolve from a configurable base directory, and the same file reached through different paths or symlinks shares one identity. Because this backend shares the host filesystem, it can also map an absolute host path into the process path used by this execution world. Writes are atomic and preserve file permissions; the optional version guard makes stale overwrites fail instead of clobbering. Choose it when a process needs direct, unconfined access to host files; choose `fs-sandbox` when mutations must be confined, or `fs-e2b` when file state belongs in a remote execution world.

+## Use this package
+
+Mount this backend when a composition needs `ctx.fs` backed by the real host filesystem and accepts a process-local implementation. The common path is explicit: load the backend, give it a base directory, and the model-facing tools (`dsh-tool-fs`) or your own plugins can read, write, and edit files.
+
+### When to choose it
+
+Choose `fs-local` for ordinary host-file access in a single process. Choose [`fs-sandbox`](../fs-sandbox/README.md) when a session's writes and edits must be confined to its workspace and temp roots — it extends this backend and adds only the mode fence. Choose [`fs-e2b`](../../e2b/fs-e2b/README.md) when files must live in a remote execution world shared with subprocesses. `config.cwd` is a resolution default, not a containment boundary: absolute paths and `..` escape it.
+
+### Minimal configuration
+
+Load the backend with a base directory; relative paths resolve against it, and absolute paths ignore it.
+
+```yaml
+- name: '@deepseek-ai/dsh-fs-local'
+  config:
+    cwd: /absolute/path/to/workspace
 ```
 
-## Behavior
+| Field | Default | Meaning |
+|---|---|---|
+| `cwd` | `process.cwd()` | Base directory for relative paths |
+| `diffBasisMaxBytes` | `10 MiB` | UTF-8 byte limit per overwrite-diff side; larger overwrites return `before: null` |
 
-- **`resolve(path, opts?)`** — a relative `path` resolves against `opts.cwd` when the caller supplies one (the model-facing tools pass the calling agent's session cwd — see [the per-session cwd Agent Note](../../../.agents/notes/implemented/architecture/2026-07-02-fs-per-session-cwd.md)), else `config.cwd` (default `process.cwd()`); an absolute `path` ignores both. `opts.signal` is checked before and after local resolution, while a remote sibling backend may use it to abort its round-trip. The `targetKey` is the file's `realpath`, so two input paths reaching the same file through symlinks share one identity, and writes/edits land on the link target (preserving the link). A not-yet-existing path uses the realpathed parent directory plus basename when the parent exists; only an unresolvable parent falls back to the absolute path. `displayPath` is the absolute (un-resolved) path.
-- **Execution-world coordinates** — `processPath` exposes the target's canonical host path, `processPathFromHostPath` accepts absolute host paths because this backend shares the host filesystem, `fileUrl` encodes target paths through Node's platform-aware URL conversion, and `contains` uses platform path semantics to test identity or descendant containment without consumers parsing `targetKey`.
-- **`stat` / `lstat`** — return target metadata or `undefined` when absent. `stat` reports `FsInfo` for an already resolved target (`version` = an opaque token derived from bigint `dev:ino:size:mtimeNs:ctimeNs`, `type` of `file`/`directory`/`other`, byte `size`); path-shaped `lstat` reports `FsPathInfo` without following the final symlink and can therefore return `symlink`. Both check cancellation before and after their asynchronous metadata probe, so an abort that lands in flight reports `FS_ABORTED` rather than stale absence.
-- **`readText` / `streamText`** — UTF-8 only. `readText` reads the whole file; `streamText` decodes chunks so a huge file need not be held whole in memory and consumers can enforce their own retention bounds. Both reject invalid UTF-8 and NUL-byte binary samples (`FS_NOT_TEXT`) and non-regular targets. The `read` tool (`@deepseek-ai/dsh-tool-fs`) owns line windowing.
-- **`readBytes`** — raw whole-file bytes with no decoding or binary rejection (the `read_image` tool validates content through the attachment service). The required byte cap short-circuits on the stat size before any content I/O; the subsequent stream reads at most one byte beyond the cap, so a file growing after stat still fails `FS_TOO_LARGE` without unbounded buffering.
-- **`listDir`** — lists one directory level in stable `name.localeCompare()` order. Each entry carries the child basename, type, resolved child target (`displayPath` under the listed directory, `targetKey` as the realpath identity), and cheap stat metadata (`version`, plus `size` for regular files). It never opens or decodes file contents. Missing targets report `FS_NOT_FOUND`, file/special-file targets report `FS_NOT_DIRECTORY`, aborted calls report `FS_ABORTED`, permission failures report `FS_PERMISSION_DENIED`, and other listing or child metadata I/O failures report `FS_IO_ERROR`. Broken/disappeared children are returned as `other` without metadata, but permission/IO failures while resolving a child fail the whole listing with a structured `FsError`.
-- **`writeText`** — atomic: writes to a temp file opened exclusively (`wx`, `0o600`) inside a randomly-named private staging dir (`0o700`) next to the target, then fsyncs and publishes. An existing file's mode is preserved, while new files default to `0o600`; on Windows a new file inherits the destination directory's DACL, while replacement copies the target DACL onto the empty temp before writing and publishes through `ReplaceFileW` so the original access policy survives ([Windows DACL preservation Agent Note](../../../.agents/notes/implemented/bug-fix/2026-07-19-windows-atomic-write-dacl-preservation.md)). The `expected` guard is OPTIONAL: omitting it unconditionally creates-or-overwrites; `createIfAbsent` hard-links the staged file into place as an atomic no-replace publication, so a regular file created after the initial probe is preserved and rejected with `FS_NOT_OBSERVED`, while a non-regular path entry is preserved and rejected with `FS_NOT_REGULAR_FILE`; `replaceIfVersion` replaces only at the observed version (a missing target or mismatch is `FS_STALE_VERSION`). An overwrite returns the prior text as its contextual diff basis only when both the opened prior file and UTF-8 replacement are strictly below `config.diffBasisMaxBytes` (default 10 MiB). The descriptor read enforces that limit even if an external writer replaces or changes the file size after the initial probe. Otherwise the provider returns `before: null`, so presentation uses its whole-file fallback.
-- **`editText`** — atomic literal read-modify-write over the same primitive, serialized per target by a mutation lock. The `expected` guard is OPTIONAL: when supplied it verifies the version BEFORE literal matching (a stale edit reports `FS_STALE_VERSION`, never `FS_EDIT_NOT_FOUND`/`FS_AMBIGUOUS_EDIT` against newer content); omitting it edits the current content unconditionally. A missing target reports `FS_STALE_VERSION` either way. LF-normalizes for matching, restores the file's dominant CRLF/LF style, and rejects empty `oldString` / zero matches (`FS_EDIT_NOT_FOUND`) or ambiguous multi-matches without `replace_all` (`FS_AMBIGUOUS_EDIT`).
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-fs-local) is the exhaustive source for every accepted field and its JSDoc.
 
-The package-root SDK API is the default/named `LocalFileSystem` class plus `Config`. Raw I/O lives in `src/fsio.ts` (Cordis-free, independently unit-tested); `src/index.ts` is the thin service wiring.
+### What you can do
 
+Read any regular UTF-8 text file whole or as a stream, read raw bytes up to a cap you choose, and list one directory level in stable name order. Create or replace a file atomically, and apply a literal text edit atomically; both mutations serialize per file, so concurrent writers never interleave. The version guard is optional: omit it for unconditional create-or-overwrite, or supply it to fail when the file changed since you last observed it.
+
+Failures are typed `FsError`s with stable codes — `FS_NOT_FOUND`, `FS_NOT_TEXT` (binary content), `FS_STALE_VERSION` (changed since observation), `FS_EDIT_NOT_FOUND` or `FS_AMBIGUOUS_EDIT` (no unique literal match), and others — so callers branch on the code, never on message text. A missing target on a guarded edit reports `FS_STALE_VERSION` either way.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the local backend and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The backend builds on three ideas:
+
+- **Realpath identity.** The `targetKey` is the file's `realpath`, so two input paths reaching the same file through symlinks share one identity, and writes land on the link target while preserving the link.
+- **Atomic publication.** Writes stage into an exclusive temp file inside a private staging directory next to the target, fsync, then publish; an existing file's mode is preserved and Windows DACLs survive replacement.
+- **One mutation critical section.** A per-target FIFO lock serializes read→guard→write windows, so concurrent writes and edits are deterministically ordered — one wins, the rest see the new version and reject as stale.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Service wiring: `LocalFileSystem`, `Config`, per-target mutation lock |
+| [`src/fsio.ts`](src/fsio.ts) | Cordis-free raw I/O: probe, reads, atomic write, literal edit, line-ending handling |
+| [`src/win32.ts`](src/win32.ts) | Windows-specific DACL preservation for atomic replacement |
+
+### Write path
+
+Each write probes the target, enforces the optional guard (`createIfAbsent` or `replaceIfVersion`), captures a bounded `before` diff basis when both sides are small enough, stages the new content next to the target, fsyncs, and publishes atomically. Guarded creation uses a hard-link publication that never replaces a concurrent creator, rejecting it with `FS_NOT_OBSERVED` instead.
+
+### Edit path
+
+Each edit probes, verifies the version guard before literal matching (so stale edits report `FS_STALE_VERSION`, never a misleading no-match), reads the file, applies the literal replacement with LF normalization, restores the file's dominant line-ending style, and republishes — all inside the per-target lock.
+
+### Ownership and invariants
+
+Raw I/O is Cordis-free and independently unit-tested in `src/fsio.ts`; `src/index.ts` stays thin wiring. `config.cwd` is a resolution default only — containment is the job of `fs-sandbox` or a `tools/execute` permission plugin. Cancellation is a best-effort `AbortSignal` checked before and after each asynchronous probe.

 [English](README.md) | 中文
 
-`ctx.fs` 提供方约定（[`@deepseek-ai/dsh-fs`](../fs)）的**本地文件系统实现**。它使用宿主文件系统支持十二个 `FileSystem` 原语；将其作为插件加载会填充 `ctx.fs`。
+## 概述
 
-```ts ignore-check
-import { LocalFileSystem } from '@deepseek-ai/dsh-fs-local'
+`dsh-fs-local` 在宿主文件系统上实现 `ctx.fs` 文件系统约定（[`dsh-fs`](../fs/README.zh.md)）：把它作为插件加载后，`ctx.fs` 就拥有真实的文件访问能力——针对本机文件的解析、读取、列出、原子写入与字面量编辑。相对路径从可配置的基准目录解析，经不同路径或符号链接到达的同一文件共享一个身份。由于本后端共享宿主文件系统，它还可以把绝对宿主路径映射为此执行世界使用的进程路径。写入是原子的并保留文件权限；可选版本防护让陈旧覆盖失败而不是静默覆盖。当进程需要直接、不受约束地访问宿主文件时选择它；需要约束变更时选择 `fs-sandbox`，文件状态属于远程执行世界时选择 `fs-e2b`。
 
-await ctx.plugin(LocalFileSystem, { cwd: process.cwd() })

+## 使用本包
+
+当组合需要由真实宿主文件系统支撑的 `ctx.fs`、且可以接受进程本地实现时，挂载此后端。常用路径是显式的：加载后端、给出基准目录，然后面向模型的工具（`dsh-tool-fs`）或你自己的插件即可读取、写入和编辑文件。
+
+### 何时选择
+
+普通宿主文件访问请选择 `fs-local`。会话的写入与编辑必须限制在工作区与临时根目录内时，选择 [`fs-sandbox`](../fs-sandbox/README.zh.md)——它扩展此后端，只增加模式围栏。文件必须位于与子进程共享的远程执行世界时，选择 [`fs-e2b`](../../e2b/fs-e2b/README.zh.md)。`config.cwd` 只是解析默认值，不是约束边界：绝对路径与 `..` 都可以逃逸它。
+
+### 最小配置
+
+加载后端并给出基准目录；相对路径以它为基准解析，绝对路径忽略它。
+
+```yaml
+- name: '@deepseek-ai/dsh-fs-local'
+  config:
+    cwd: /absolute/path/to/workspace
 ```
 
-## 行为
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `cwd` | `process.cwd()` | 相对路径的基准目录 |
+| `diffBasisMaxBytes` | `10 MiB` | 每次覆写 diff 一侧的 UTF-8 字节上限；更大的覆写返回 `before: null` |
 
-- **`resolve(path, opts?)`**：相对 `path` 在调用方提供 `opts.cwd` 时以该值为基准解析（面向模型的工具会传入调用 agent（智能体）的会话 cwd；见[每会话 cwd Agent Note](../../../.agents/notes/implemented/architecture/2026-07-02-fs-per-session-cwd.zh.md)），否则以 `config.cwd` 为基准（默认 `process.cwd()`）；绝对 `path` 会忽略两者。`opts.signal` 会在本地解析前后检查，远程同级后端则可以用它中止往返。`targetKey` 是文件的 `realpath`，因此经符号链接到达同一文件的两个输入路径会共享一个身份，写入/编辑落在链接目标上，同时保留链接。尚不存在的路径在父目录存在时使用 realpath 后的父目录加 basename；只有父目录无法解析时才回退到绝对路径。`displayPath` 是绝对但未经解析的路径。
-- **执行世界坐标**：`processPath` 公开目标的规范化宿主路径。由于该后端共享宿主文件系统，`processPathFromHostPath` 接受绝对宿主路径。`fileUrl` 通过 Node 的平台感知 URL 转换对目标路径编码。`contains` 使用平台路径语义检查身份相等或后代包含关系，消费方无需解析 `targetKey`。
-- **`stat` / `lstat`**：返回目标元数据；目标不存在时返回 `undefined`。`stat` 为已解析目标报告 `FsInfo`（`version` 是由 bigint `dev:ino:size:mtimeNs:ctimeNs` 派生的不透明 token，`type` 为 `file`/`directory`/`other`，`size` 以字节计）；路径形态的 `lstat` 不跟随最后一个符号链接，报告 `FsPathInfo`，因此可以返回 `symlink`。两者都会在异步元数据探测前后检查取消，因此异步探测进行期间发生的中止会报告 `FS_ABORTED`，而非陈旧的不存在结果。
-- **`readText` / `streamText`**：只支持 UTF-8。`readText` 读取整个文件；`streamText` 按分片解码，因此超大文件无需整体保存在内存中，消费方也可以自行限制保留量。两者都会拒绝无效 UTF-8、包含 NUL 字节的二进制样本（`FS_NOT_TEXT`）以及非普通文件目标。`read` 工具（`@deepseek-ai/dsh-tool-fs`）拥有行窗口逻辑。
-- **`readBytes`**：按原始字节读取整个文件，不做解码或二进制拒绝（`read_image` 工具通过附件服务校验内容）。必填的字节上限在任何内容 I/O 之前先按 stat 大小短路；随后的流最多多读一个字节，因此 stat 之后增长的文件仍会以 `FS_TOO_LARGE` 失败，不会无界缓冲。
-- **`listDir`**：按稳定的 `name.localeCompare()` 顺序列出一层目录。每个条目携带子项 basename、类型、解析后的子目标（`displayPath` 位于所列目录下，`targetKey` 是 realpath 身份）和低成本 stat 元数据（`version`，普通文件另有 `size`）。它绝不会打开或解码文件内容。缺失目标报告 `FS_NOT_FOUND`，文件/特殊文件目标报告 `FS_NOT_DIRECTORY`，已中止调用报告 `FS_ABORTED`，权限失败报告 `FS_PERMISSION_DENIED`，其他列出或子项元数据 I/O 失败报告 `FS_IO_ERROR`。损坏/消失的子项以无元数据的 `other` 返回，但解析子项时出现权限/I/O 失败会让整个列表以结构化 `FsError` 失败。
-- **`writeText`**：原子写入。它会向排他打开的临时文件（`wx`、`0o600`）写入；该文件位于目标旁随机命名的私有暂存目录（`0o700`）内，随后执行 fsync 并发布。现有文件的 mode 会保留，新文件默认为 `0o600`；Windows 上的新文件继承目标目录的 DACL，而替换会在写入前把目标 DACL 复制到空临时文件，并通过 `ReplaceFileW` 发布，使原访问策略得以保留（见 [Windows DACL 保留 Agent Note](../../../.agents/notes/implemented/bug-fix/2026-07-19-windows-atomic-write-dacl-preservation.zh.md)）。`expected` 防护是可选的：省略时无条件创建或覆盖；`createIfAbsent` 通过硬链接把暂存文件发布到目标位置，以实现原子且不替换的发布，因此初始探测后创建的普通文件会被保留，并以 `FS_NOT_OBSERVED` 拒绝本次写入；非普通路径条目也会被保留，并以 `FS_NOT_REGULAR_FILE` 拒绝；`replaceIfVersion` 只在观察到的版本上替换（目标缺失或版本不匹配均为 `FS_STALE_VERSION`）。仅当打开后的旧文件和 UTF-8 替换内容都严格低于 `config.diffBasisMaxBytes`（默认 10 MiB）时，覆写才返回旧文本作为上下文 diff 基础。即使外部写入方在初次探测后替换文件或改变文件大小，文件描述符读取仍会强制执行该上限；否则提供方返回 `before: null`，由展示层使用整文件回退。
-- **`editText`**：在同一原语之上依次执行原子的字面量读取、修改和写入，并通过变更锁按目标串行化。`expected` 防护是可选的：提供时，会在字面量匹配之前校验版本（陈旧编辑报告 `FS_STALE_VERSION`，绝不会针对较新内容报告 `FS_EDIT_NOT_FOUND`/`FS_AMBIGUOUS_EDIT`）；省略时，无条件编辑当前内容。无论哪种情况，目标缺失都报告 `FS_STALE_VERSION`。匹配时规范化为 LF，随后恢复文件主要的 CRLF/LF 风格；空 `oldString` / 零匹配报告 `FS_EDIT_NOT_FOUND`，未设置 `replace_all` 的多个匹配则报告 `FS_AMBIGUOUS_EDIT`。
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-fs-local)是每个受支持字段及其 JSDoc 的穷尽式真源。
 
-包根 SDK 接口包含默认/具名 `LocalFileSystem` 类和 `Config`。原始 I/O 位于 `src/fsio.ts`（不依赖 Cordis，单独进行单元测试）；`src/index.ts` 是轻量服务接线。
+### 你能做什么
 
+完整或流式读取任意普通 UTF-8 文本文件，按你选择的上限读取原始字节，并按稳定名称顺序列出一层目录。原子地创建或替换文件，并原子地应用字面量文本编辑；两个变更操作都按文件串行化，并发写入方绝不会交错。版本防护是可选的：省略它即无条件创建或覆盖，提供它则在文件自上次观察以来发生变化时失败。
+
+失败是携带稳定错误码的类型化 `FsError`——`FS_NOT_FOUND`、`FS_NOT_TEXT`（二进制内容）、`FS_STALE_VERSION`（自观察以来已变化）、`FS_EDIT_NOT_FOUND` 或 `FS_AMBIGUOUS_EDIT`（无唯一字面量匹配）等——因此调用方依据错误码分支，绝不解析消息文本。带防护的编辑遇到缺失目标时，无论哪种情况都报告 `FS_STALE_VERSION`。

+
+本节解释本地后端背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+后端建立在三个想法之上：
+
+- **Realpath 身份。** `targetKey` 是文件的 `realpath`，因此经符号链接到达同一文件的两个输入路径共享一个身份，写入落在链接目标上，同时保留链接。
+- **原子发布。** 写入先写入目标旁私有暂存目录内的独占临时文件，执行 fsync 后发布；现有文件的 mode 会保留，Windows 上的 DACL 也会在替换后存活。
+- **单一变更临界区。** 每目标 FIFO 锁串行化读取→防护→写入窗口，并发写入与编辑因此被确定性排序——一方胜出，其余看到新版本并以陈旧拒绝。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 服务接线：`LocalFileSystem`、`Config`、每目标变更锁 |
+| [`src/fsio.ts`](src/fsio.ts) | 不依赖 Cordis 的原始 I/O：探测、读取、原子写入、字面量编辑、行尾处理 |
+| [`src/win32.ts`](src/win32.ts) | 原子替换的 Windows 专属 DACL 保留 |
+
+### 写入路径
+
+每次写入先探测目标、执行可选防护（`createIfAbsent` 或 `replaceIfVersion`）、在两侧都足够小时捕获有界的 `before` diff 基础、把新内容暂存到目标旁、fsync，然后原子发布。带防护的创建使用绝不替换并发创建者的硬链接发布，并以 `FS_NOT_OBSERVED` 拒绝它。
+
+### 编辑路径
+
+每次编辑先探测、在字面量匹配前校验版本防护（陈旧编辑因此报告 `FS_STALE_VERSION`，绝不会给出误导性的无匹配）、读取文件、以 LF 规范化执行字面量替换、恢复文件主要的行尾风格，然后重新发布——全部在每目标锁内完成。
+
+### 归属与不变式
+
+原始 I/O 不依赖 Cordis，在 `src/fsio.ts` 中独立单元测试；`src/index.ts` 保持为轻量接线。`config.cwd` 只是解析默认值——约束是 `fs-sandbox` 或 `tools/execute` 权限插件的工作。取消是尽力而为的 `AbortSignal`，在每次异步探测前后检查。

 # @deepseek-ai/dsh-fs-observation-policy
 
 English | [中文](README.zh.md)
 
-The **fs-observation-policy plugin**: it records observed presence or absence and adds read-before-edit plus guarded write/edit on top of the `ctx.fs` provider contract ([`@deepseek-ai/dsh-fs`](../fs)) — through the `fs/*` event gate, **NOT** through a method service. This plugin registers **no** `ctx.fsPolicy` service and has no public `read`/`write`/`edit`/`resolve` methods. It is the policy third of the filesystem stack: not a swappable seam, but the policy that does not belong on the `FileSystem` provider base class.
+## Summary
 
-```ts
-import type { Context } from '@deepseek-ai/cordis'
-import * as FsPolicy from '@deepseek-ai/dsh-fs-observation-policy'
+`dsh-fs-observation-policy` adds the read-before-edit policy to the `ctx.fs` filesystem contract ([`dsh-fs`](../fs/README.md)): it records which files the calling session has observed, and guards every write and edit with that record — an unseen file can only be created, an observed file can only be replaced at the version last seen, and editing requires a prior read. It participates through the `fs/*` events only, so it registers no service and has no public methods; removing it leaves the bare provider's unconditional mutation behavior instead of breaking the tools. Loading it alongside a backend (`fs-local`, `fs-sandbox`) and the tools (`tool-fs`) makes model file edits fail with a clear remedy until the file has been read. Choose it for deployments that want agents to read before they mutate files.

+## Use this package
+
+Load this plugin alongside a `ctx.fs` backend and the `dsh-tool-fs` tools when a deployment wants the model to read a file before it can overwrite or edit it. The plugin needs no configuration and injects no service; it only listens for the `fs/*` events the tools dispatch.
+
+### Minimal composition
+
+Load a backend, then this plugin, then the tools. The policy listener should be the first decider registered for the `fs/*`-intent slots.
+
+```yaml

+- name: '@deepseek-ai/dsh-fs-observation-policy'
+- name: '@deepseek-ai/dsh-tool-fs'
 ```
 
-## The four-layer split
+### What changes for the model
 
-| Layer | Package | Role |
-|---|---|---|
-| tool / executor | `@deepseek-ai/dsh-tool-fs` | model-facing schemas + read windowing + text rendering; reads/writes/edits via `ctx.fs`, dispatches the `fs/*` events |
-| policy | `@deepseek-ai/dsh-fs-observation-policy` (this) | observed-state + read-before-edit + version-guarded write/edit, contributed through the `fs/*` event gate (no service) |
-| provider contract | `@deepseek-ai/dsh-fs` | `ctx.fs`: text IO + atomic mutation primitives (optional version guard); owns the `fs/*` event vocabulary |
-| provider | `@deepseek-ai/dsh-fs-local` | local implementation of `ctx.fs` |
+With the policy mounted, `write` creates new files but refuses to overwrite an existing file that the session has not read, `edit` requires a prior read of the target, and a file that changed since it was read fails with `FS_STALE_VERSION`. Absence is recorded too: reading a missing file marks it confirmed absent, so a later `write` may recreate it through the guarded-create flow. A session resumes with no observed state, so it must re-read files before guarded mutations succeed again.
 
-## How the gate participates
+### Failures and recovery
 
-Three `fs/*` events (declared by `@deepseek-ai/dsh-fs`, dispatched by `@deepseek-ai/dsh-tool-fs`):
+An edit without a prior observation fails with code `FS_NOT_OBSERVED` and message `edit requires reading "<path>" first`; editing a target observed absent fails with `FS_NOT_FOUND`. The tools append the recovery instruction — re-read the file, then retry — while preserving the code. Following the remedy on an externally deleted file records absence, so the next guarded write can recreate it without clobbering a concurrent creator.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the policy plugin and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The plugin is built on two ideas:
+
+- **Event gate, not method service.** The plugin influences the world only through the `fs/*` events, so it registers no `ctx.fsPolicy` service and has no public methods. Removing it cannot break `dsh-tool-fs` at a service-injection boundary — the tool falls through to the bare provider.
+- **Observed state is a prior-observation record.** A weak owner-to-target map holds three logical states — unseen, confirmed absent, or present at a version. The plugin performs no filesystem I/O of its own; it converts recorded state into the provider's optional guard, and the provider performs the atomic freshness check.
+
+### Source map
+
+| File | Role |
 |---|---|
-| `fs/write-intent` | Unseen or observed absent → `{ kind: 'createIfAbsent' }`; observed present → `{ kind: 'replaceIfVersion', version: vObserved }`. Single-slot decision; does NOT call `next()`. |
-| `fs/edit-intent` | Unseen → `FS_NOT_OBSERVED`; observed absent → `FS_NOT_FOUND`; observed present → `{ version: vObserved }` as the CAS basis. Single-slot decision; does NOT call `next()`. |
-| `fs/observed` | Records `{ kind: 'present', version }` or `{ kind: 'absent' }` for this owner+target. Synchronous, side-effect-only `WeakMap.set`. |
+| [`src/index.ts`](src/index.ts) | The three `fs/*` listeners and the observed-state gate |
+| [`src/types.ts`](src/types.ts) | The opaque event actor shape from which the owner session is derived |
 
-## Observed state is the prior-observation record; freshness is provider CAS
+### Decision flow
 
-Observed state is a weak owner-to-target map with three logical states: unseen, confirmed absent, or present at a version. A successful file read or mutation records presence; a metadata miss from `read` or the `str_replace_editor` `view`, `str_replace`, or `insert` command records absence before returning `FS_NOT_FOUND`. The plugin performs no filesystem I/O: it converts that state into a provider guard. Presence supplies the observed version, while absence lets only a `createIfAbsent` write proceed; edit has no version basis and returns `FS_NOT_FOUND`. A windowed read observes the whole file version, so a later targeted edit is allowed only while that file remains unchanged. State is discarded on plugin disposal and is not persisted across sessions.
+`fs/write-intent` resolves unseen or confirmed absent to `{ kind: 'createIfAbsent' }` and observed present to `{ kind: 'replaceIfVersion', version: vObserved }`. `fs/edit-intent` rejects an unseen target with `FS_NOT_OBSERVED`, a confirmed-absent target with `FS_NOT_FOUND`, and otherwise supplies the observed version as the compare-and-swap basis. `fs/observed` records `{ kind: 'present', version }` or `{ kind: 'absent' }` for the owner and target — a synchronous, side-effect-only `WeakMap.set`, because successful mutations have already committed.
 
-## Single-slot, first-wins
+### Single-slot, first-wins
 
-The `fs/write-intent`/`fs/edit-intent` slots hold exactly one decider — this plugin fully decides and does not call `next()`. The slot is first-wins by registration order; this plugin owning it is the default-deployment convention, not an event-enforced invariant (a decider registered before / `prepend`ed would win instead). This is not a composable authorization chain — layered permission/audit/sandbox interception belongs on `tools/execute`.
+Each intent slot holds exactly one decider: this plugin fully decides and never calls `next()`. The slot is first-wins by registration order — this plugin owning it is the default-deployment convention, not an event-enforced invariant. Layered permission, audit, or sandbox interception belongs on the `tools/execute` waterfall instead.
 
-## No method coupling
+### Lifecycle
 
-Because the plugin influences the world only through events, removing it does not break `@deepseek-ai/dsh-tool-fs` at a service-injection boundary: the tool falls through to the bare `ctx.fs` provider (unconditional write/edit, no observed-state). Loading it back layers the policy on. That graceful add/remove is the whole point of the event gate over a mandatory method service.
+Observed state is dropped on plugin disposal (HMR safety) and is never persisted across sessions — a resumed session starts with no observations.

 ### Filesystem tool outcome
 
 #### What the model sees
 
-This plugin adds no prompt or schema. It rejects an edit without a prior observation with code `FS_NOT_OBSERVED` and exact message `edit requires reading "<path>" first`; editing a target just observed absent returns `FS_NOT_FOUND`. Guarded mutations whose positive observation is stale propagate the provider-owned `FS_STALE_VERSION` error. [`dsh-tool-fs`](../tool-fs/README.md) owns the model-facing error wrapper, which appends the recovery instruction to `FS_STALE_VERSION` (`— re-read the file, then retry`) and `FS_NOT_OBSERVED` (`— read the file, then retry`) messages while preserving the code. Following the stale remedy on an externally deleted target now records absence: the next guarded write may recreate it with `createIfAbsent`, while the provider atomically preserves any concurrent creator.

 [English](README.md) | 中文
 
-**fs-observation-policy 插件**：它记录观测到的存在或缺失状态，并在 `ctx.fs` 提供方约定（[`@deepseek-ai/dsh-fs`](../fs)）之上增加编辑前读取和带防护的写入/编辑；它通过 `fs/*` 事件门禁参与，**不是**通过方法服务。该插件**不**注册 `ctx.fsPolicy` 服务，也没有公开的 `read`/`write`/`edit`/`resolve` 方法。它是文件系统栈的政策层：不是可替换 seam，而是不应位于 `FileSystem` 提供方基类上的政策。
+## 概述
 
-```ts
-import type { Context } from '@deepseek-ai/cordis'
-import * as FsPolicy from '@deepseek-ai/dsh-fs-observation-policy'
+`dsh-fs-observation-policy` 在 `ctx.fs` 文件系统约定（[`dsh-fs`](../fs/README.zh.md)）之上添加编辑前读取策略：它记录调用会话观察过哪些文件，并用该记录防护每一次写入与编辑——未见文件只能被创建，已观察文件只能在最后看到的版本上被替换，编辑则要求先读取。它只通过 `fs/*` 事件参与，因此不注册任何服务，也没有公开方法；移除它只会让工具回到裸提供方的无条件变更行为，而不会破坏工具。把它与后端（`fs-local`、`fs-sandbox`）和工具（`tool-fs`）一起加载，会让模型在读取文件之前无法成功编辑文件，并收到清晰的恢复提示。需要 agent（智能体）先读后改的部署请选择它。

+## 使用本包
+
+当部署希望模型在覆盖或编辑文件之前先读取该文件时，把本插件与 `ctx.fs` 后端及 `dsh-tool-fs` 工具一起加载。插件无需配置，也不注入任何服务；它只监听工具分派的 `fs/*` 事件。
+
+### 最小组合
+
+先加载后端，再加载本插件，最后加载工具。策略监听器应当是 `fs/*` 意图槽位上第一个注册的决策器。
+

-## 四层拆分
+### 对模型而言的变化
 
-| 层 | 包 | 角色 |
-|---|---|---|
-| 工具/执行器 | `@deepseek-ai/dsh-tool-fs` | 面向模型的 schema、读取窗口和文本渲染；通过 `ctx.fs` 读取/写入/编辑，并分派 `fs/*` 事件 |
-| 策略 | `@deepseek-ai/dsh-fs-observation-policy`（本包） | 通过 `fs/*` 事件门禁提供已观察状态、编辑前读取和版本防护的写入/编辑（无服务） |
-| 提供方约定 | `@deepseek-ai/dsh-fs` | `ctx.fs`：文本 I/O 与原子变更原语（可选版本防护）；拥有 `fs/*` 事件词汇 |
-| 提供方 | `@deepseek-ai/dsh-fs-local` | `ctx.fs` 的本地实现 |
+挂载策略后，`write` 可以创建新文件，但拒绝覆盖会话未读取过的现有文件；`edit` 要求先读取目标；自读取以来发生变化（包括缺失）的文件以 `FS_STALE_VERSION` 失败。缺失也会被记录：读取缺失文件会把它标记为确认缺失，因此随后的 `write` 可以通过防护创建流程重新创建它。会话恢复后不携带任何已观察状态，因此必须重新读取文件，防护变更才能再次成功。
 
-## 门禁的参与方式
+### 失败与恢复
 
-三个 `fs/*` 事件（由 `@deepseek-ai/dsh-fs` 声明，`@deepseek-ai/dsh-tool-fs` 分派）：
+没有先前观测的编辑以代码 `FS_NOT_OBSERVED` 和消息 `edit requires reading "<path>" first` 失败；编辑被观测为缺失的目标以 `FS_NOT_FOUND` 失败。工具会追加恢复指令——先重新读取文件再重试——同时保留错误码。在外部删除的文件上遵循该恢复指令会记录缺失，因此下一次防护写入可以重新创建它，而不会覆盖并发创建者。

+
+本节解释策略插件背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+插件建立在两个想法之上：
+
+- **事件门禁，而非方法服务。** 插件只通过 `fs/*` 事件影响外部世界，因此不注册 `ctx.fsPolicy` 服务，也没有公开方法。移除它不会在服务注入边界破坏 `dsh-tool-fs`——工具会直接落到裸提供方。
+- **已观察状态是先前观察记录。** 一张以所有者为弱键、记录各目标的映射表持有三种逻辑状态——未见、确认缺失、存在于某个版本。插件本身不执行任何文件系统 I/O；它把记录的状态转换为提供方的可选防护，由提供方执行原子新鲜度检查。
+
+### 源码地图
+
+| 文件 | 职责 |
 |---|---|
-| `fs/write-intent` | 未见或已观测为缺失 → `{ kind: 'createIfAbsent' }`；已观测为存在 → `{ kind: 'replaceIfVersion', version: vObserved }`。单 slot 决策；不调用 `next()`。 |
-| `fs/edit-intent` | 未见 → `FS_NOT_OBSERVED`；已观测为缺失 → `FS_NOT_FOUND`；已观测为存在 → 返回 `{ version: vObserved }` 作为 CAS 基础。单 slot 决策；不调用 `next()`。 |
-| `fs/observed` | 为该所有者与目标记录 `{ kind: 'present', version }` 或 `{ kind: 'absent' }`。同步、只有副作用的 `WeakMap.set`。 |
+| [`src/index.ts`](src/index.ts) | 三个 `fs/*` 监听器与已观察状态门禁 |
+| [`src/types.ts`](src/types.ts) | 不透明事件参与者形态，从中派生所有者会话 |
 
-## 已观察状态是先前观察记录；新鲜度由提供方 CAS 保证
+### 决策流程
 
-观测状态是一张以所有者为弱键、记录各目标的映射表，具有三种逻辑状态：未见、确认缺失、存在于某个版本。成功读取文件或变更会记录存在；`read` 的元数据未命中，或 `str_replace_editor` 的 `view`、`str_replace`、`insert` 命令发生元数据未命中时，都会在返回 `FS_NOT_FOUND` 前记录缺失。插件不执行文件系统 I/O：它把该状态转换为提供方防护。存在状态提供观测到的版本；缺失状态只允许 `createIfAbsent` 写入继续，edit 因没有版本基准而返回 `FS_NOT_FOUND`。窗口读取会观察整个文件的版本，因此只有文件保持不变时才允许后续的定向编辑。插件 dispose（资源释放）时会丢弃状态，并且不会跨会话持久化。
+`fs/write-intent` 把未见或确认缺失解析为 `{ kind: 'createIfAbsent' }`，把已观测存在解析为 `{ kind: 'replaceIfVersion', version: vObserved }`。`fs/edit-intent` 以 `FS_NOT_OBSERVED` 拒绝未见目标，以 `FS_NOT_FOUND` 拒绝确认缺失的目标，否则提供观察到的版本作为比较并交换的基础。`fs/observed` 为该所有者与目标记录 `{ kind: 'present', version }` 或 `{ kind: 'absent' }`——同步、只有副作用的 `WeakMap.set`，因为成功的变更已经提交。
 
-## 单 slot、先到者胜
+### 单槽、先到者胜
 
-`fs/write-intent`/`fs/edit-intent` slot 只容纳一个决策器；本插件会完整决策，不调用 `next()`。slot 按注册顺序先到者胜；由本插件拥有 slot 只是默认部署约定，不是事件强制的不变式（更早注册或通过 `prepend` 注册的决策器会胜出）。这不是可组合的授权链；分层权限/审计/沙箱拦截属于 `tools/execute`。
+每个意图槽位只容纳一个决策器：本插件会完整决策，绝不调用 `next()`。槽位按注册顺序先到者胜——由本插件拥有槽位只是默认部署约定，不是事件强制的不变式。分层权限、审计或沙箱拦截属于 `tools/execute` waterfall（瀑布式事件）。
 
-## 不与方法耦合
+### 生命周期
 
-由于插件只通过事件影响外部世界，移除它不会在服务注入边界破坏 `@deepseek-ai/dsh-tool-fs`：工具会直接落到裸 `ctx.fs` 提供方（无条件写入/编辑，无已观察状态）。重新加载插件后，策略会重新生效。相比必需的方法服务，这种可平稳增删的性质正是事件门禁的全部目的。
+已观察状态在插件 dispose（资源释放）时丢弃（HMR 安全），且绝不跨会话持久化——恢复的会话从无观察状态开始。

It inherits every text-storage mechanic verbatim (resolve, stat, read/stream, list, the atomic write, the read-match-write edit critical section) and adds only a per-call MODE fence on `writeText`/`editText`. Reads always pass through — every mode permits reading.
+## Summary
 
-Its plugin config is the local backend config unchanged: `cwd` remains the relative-path resolution default, and `diffBasisMaxBytes` bounds the optional overwrite contextual-diff basis.
+`dsh-fs-sandbox` provides the sandbox-enforcing `ctx.fs` backend: it extends [`fs-local`](../fs-local/README.md) with every text-storage behavior intact and adds only a per-call mode fence on writes and edits, while reads always pass through. Under `read-only` every mutation is refused; under `workspace-write` a mutation is allowed only when the target sits under the session workspace or a platform temp root; under `danger-full-access` mutations run unfenced. Loading it instead of `fs-local`, together with the shared `ctx.sandboxPolicy` service, is the whole swap — the model-facing tools and the policy plugin are untouched. A denial is a structured `FS_SANDBOX_DENIED` error that the tools render as the familiar `[sandbox: file access denied under <mode> mode]` marker with a same-turn escalation hint. Choose it when a session's file mutations must be confined to its workspace.
 
-Loading it INSTEAD OF `dsh-fs-local`, together with a [`ctx.sandboxPolicy`](../../sandbox/sandbox-policy/README.md), is the whole swap; the model-facing tools (`dsh-tool-fs`) are untouched. The tool layer resolves the calling session's mode and cwd into the SAME per-call policy bash receives, so the two families never confine to different roots.

-- `read-only` — denies every mutation with the structured `FS_SANDBOX_DENIED`.
-- `workspace-write` — allows a mutation only when the target canonicalizes under a writable root: the workspace root plus the platform temp areas (`/tmp`, `os.tmpdir()`), the SAME set the Seatbelt profile grants, derived from the one [`writableRoots`](../../sandbox/README.md) function so the fs fence and the bash runner cannot drift. Canonical spellings use a lexical fast path; an identity-based ancestor fallback recognizes alias-equivalent roots such as Windows long names and 8.3 names without treating unrelated prefixes as contained. The target is re-canonicalized immediately before delegating, so an ancestor symlink swapped since the tool resolved it is caught.
-- `danger-full-access` — delegates unfenced.

+## Use this package
 
-## Threat model: a policy fence, not a kernel boundary
+Mount this backend instead of `fs-local` when the model's file writes and edits must be confined by the session's sandbox mode, while reads stay unconfined. The fence applies per call: the tool layer resolves the calling session's mode and workspace root into the same policy the bash runner receives, so the filesystem and shell families never confine to different roots.
 
-The fence is a check in TRUSTED code over a MODEL-CONTROLLED path — the operations are the seam's own (open, rename), only the target path is untrusted, so canonicalize-then-contain is the complete answer to this surface. This mirrors the `code-runtime` stance: containment, not a security boundary. Kernel-grade isolation of untrusted CODE stays `ctx.shell`'s job ([`dsh-bash-sandbox`](../../shell/bash-sandbox/README.md)). The residual TOCTOU (an ancestor symlink swapped between the containment re-check and the syscall) is narrowed by re-canonicalizing immediately before the write and is accepted for this threat model; a kernel-tight boundary needs `openat2`-class primitives not worth their portability cost here.
+### Minimal composition
 
-A denial is a structured `FsError` (`FS_SANDBOX_DENIED`, carrying the effective mode) — no stderr text inference (unlike bash's kernel denials), because an in-process fence knows exactly what it refused. The model-facing `[sandbox: file access denied under <mode> mode]` marker and the one-approved-wider retry live in the tool layer (`dsh-tool-fs`), exactly as bash's do. See [the cross-family fs sandbox Agent Note](../../../.agents/notes/implemented/feature/2026-07-14-cross-family-fs-sandbox.md).
+Load the shared policy service, then this backend, then the tools; the read-before-edit policy plugin stays optional.
 
+```yaml
+- name: '@deepseek-ai/dsh-sandbox-policy'
+- name: '@deepseek-ai/dsh-fs-sandbox'
+  config:
+    cwd: /absolute/path/to/workspace
+- name: '@deepseek-ai/dsh-tool-fs'
+```
+
+The backend's config is the local backend's unchanged (`cwd` resolution default and `diffBasisMaxBytes` overwrite bound); the [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-fs-sandbox) is the exhaustive source.
+
+### How the fence behaves
+
+The effective mode comes from the calling session's override or escalation grant, falling back to the deployment default when neither is in force. `read-only` denies every mutation with the structured `FS_SANDBOX_DENIED`. `workspace-write` allows a mutation only when the target canonicalizes under the workspace root or a platform temp area (`/tmp`, `os.tmpdir()`) — the same writable set the Seatbelt profile grants. `danger-full-access` delegates unfenced.
+
+### Observable success and failures
+
+Reads, listings, and metadata work exactly as with `fs-local`. A denied mutation returns an `FS_SANDBOX_DENIED` error carrying the effective mode; through the tools the model sees `[sandbox: file access denied under <mode> mode]` plus the one-approved-wider retry hint, identical to bash's denials. A session with an approved escalation may retry the same operation at a strictly wider mode for that one call.

+
+This section explains the design decisions behind the sandbox backend and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The fence is a policy check in trusted code over a model-controlled path — not a kernel boundary. The operations are the seam's own (open, rename); only the target path is untrusted, so canonicalize-then-contain is the complete answer to this surface. Kernel-grade isolation of untrusted code stays `ctx.shell`'s job.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | `SandboxedFileSystem`: mode fence on `writeText`/`editText`, `sandboxMode` fact |
+| [`src/containment.ts`](src/containment.ts) | Ancestor containment check with lexical fast path and identity-based fallback |
+
+### How a mutation is fenced
+
+Each mutation resolves the per-call policy (`danger-full-access` returns the caller's target untouched; `read-only` throws `FS_SANDBOX_DENIED`), then for `workspace-write` re-canonicalizes the target immediately and requires containment under one of the writable roots derived from the single `writableRoots` function — the same set the Seatbelt profile grants, so the fs fence and the bash runner cannot drift. The fresh target is the one mutated, so a symlink ancestor swapped since the tool resolved it is caught.
+
+### Threat model
+
+The residual resolve-to-syscall TOCTOU is narrowed by re-canonicalizing immediately before the write and is accepted for this threat model; a kernel-tight boundary would need `openat2`-class primitives whose portability cost is not worth it here. A denial is a structured `FsError`, not stderr inference — an in-process fence knows exactly what it refused.

+These limits define when the sandbox backend is a poor fit or needs special operational care. They are current package constraints, not a general sandbox comparison or a task backlog.
+
 - **A policy fence, not a kernel boundary** — the check is trusted code over a model-controlled path, so the residual resolve-to-syscall TOCTOU is narrowed (by the in-place re-canonicalization) but not eliminated; adversarial host processes are out of scope. Kernel-grade isolation of untrusted code stays `ctx.shell`'s.
 - **Fence-vs-runner parity is derived from one owner** — the writable set comes from `writableRoots`, shared with the Seatbelt profile; a runner profile that defines its writable set elsewhere would drift.
 - **Requires `ctx.sandboxPolicy`** — tools use it to resolve each session policy and the backend uses it for agentless-call fallbacks; the backend does not confine without it composed.

-`SandboxedFileSystem` 扩展 [`LocalFileSystem`](../fs-local/README.zh.md) 并注册为 `ctx.fs`。它逐字继承全部文本存储机制（解析、stat、读取／流式读取、列出、原子写入、按读取、匹配、写入顺序执行的编辑临界区），只为 `writeText`/`editText` 增加按调用的模式围栏。读取始终直接通过：所有模式都允许读取。
+## 概述

+当模型的文件写入与编辑必须受会话沙箱模式约束、而读取保持不受约束时，挂载此后端以替代 `fs-local`。围栏按调用生效：工具层把调用会话的模式与工作区根目录解析为与 bash runner 收到的相同策略，因此文件系统与 shell 两个能力族绝不会约束到不同根目录。
 
-围栏是在可信代码中检查模型控制的路径。操作本身属于 seam（open、rename），只有目标路径不可信，因此「规范化后检查包含关系」就是该接口的完整答案。这与 `code-runtime` 的立场相同：提供约束，但不是安全边界。不可信代码的内核级隔离仍由 `ctx.shell` 负责（[`dsh-bash-sandbox`](../../shell/bash-sandbox/README.zh.md)）。剩余 TOCTOU（在包含关系复查与系统调用之间替换祖先符号链接）会通过写入前立即重新规范化来缩小，并为该威胁模型所接受；内核严密边界需要 `openat2` 一类原语，其可移植性成本在此不值得。
+### 最小组合
 
-拒绝是结构化 `FsError`（`FS_SANDBOX_DENIED`，携带有效模式），不通过 stderr 文本推断（不同于 bash 的内核拒绝），因为进程内围栏准确知道自己拒绝了什么。面向模型的 `[sandbox: file access denied under <mode> mode]` 标记以及唯一一次获批的更宽权限重试位于工具层（`dsh-tool-fs`），与 bash 完全相同。见[跨能力族 fs 沙箱 Agent Note](../../../.agents/notes/implemented/feature/2026-07-14-cross-family-fs-sandbox.zh.md)。

+```
+
+后端的配置与本地后端完全相同（`cwd` 解析默认值与 `diffBasisMaxBytes` 覆写上限）；[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-fs-sandbox)是穷尽式真源。
+
+### 围栏行为
+
+有效模式来自调用会话的覆盖值或升级授权，两者都未生效时才回退到部署默认值。`read-only` 以结构化 `FS_SANDBOX_DENIED` 拒绝所有变更。`workspace-write` 只允许目标规范化后位于工作区根目录或平台临时区域（`/tmp`、`os.tmpdir()`）之下的变更——与 Seatbelt profile 授权的可写集合相同。`danger-full-access` 不加围栏直接委托。
+
+### 可观察的成功与失败
+
+读取、列出与元数据操作与 `fs-local` 完全一致。被拒绝的变更返回携带有效模式的 `FS_SANDBOX_DENIED` 错误；经工具，模型会看到 `[sandbox: file access denied under <mode> mode]` 及唯一一次获批更宽权限的重试提示，与 bash 的拒绝完全相同。获得批准升级的会话可以在该次调用中以严格更宽的模式重试同一操作。

-The **`FileSystem`** (`ctx.fs`) defines the storage primitives in one execution world — resolve paths, expose canonical process paths and file URIs, map shared host files, test containment, read whole or streaming text, read bounded raw bytes, inspect/list metadata, write atomically, and apply a literal edit — without saying HOW. Both mutations take their version guard **optionally**, so `ctx.fs` on its own is a complete, unconstrained storage seam. This package also owns the `fs/*` policy event vocabulary the tool dispatches and the policy plugin listens for.
+## Summary
 
-This package owns the Service Definition and provider contract layer of the four-layer filesystem stack, split so each concern can evolve (and be swapped) independently (see [the capability-seam Agent Note](../../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.md), [the filesystem capability-seam Agent Note](../../../.agents/notes/implemented/architecture/2026-06-17-filesystem-capability-seam.md), [the split-the-filesystem-seam Agent Note](../../../.agents/notes/implemented/simplification/2026-06-26-fsspec-style-fs-seam.md), and [the file-context event-gate Agent Note](../../../.agents/notes/implemented/architecture/2026-06-26-file-context-as-event-gate.md)):
+`dsh-fs` defines the `ctx.fs` filesystem service: a compact, backend-neutral contract for one execution world that resolves paths to stable identities, maps shared host files when supported, reads text and raw bytes within bounds, lists directories, and applies atomic writes and literal edits. It deliberately leaves storage mechanics to the backends that implement it — `fs-local` for the host filesystem, `fs-sandbox` for policy-enforced confinement, and `fs-e2b` for a remote execution world. Both mutations take an optional version guard, so a backend mounted without the policy plugin still gives complete, unconstrained, atomic file operations. The package also owns the `fs/*` policy-event vocabulary that the tool package dispatches and the policy plugin decides. Choose it when you need a swappable filesystem surface; the model-facing tools themselves live in `dsh-tool-fs`.
 
-| Layer | Package | Role |
-|---|---|---|
-| tool / executor | `@deepseek-ai/dsh-tool-fs` | model-facing `read`/`write`/`edit` schemas + read windowing + text rendering; reads/writes/edits via `ctx.fs`, dispatches the `fs/*` events |
-| policy | `@deepseek-ai/dsh-fs-observation-policy` | observed-state + read-before-edit + version-guarded write/edit, contributed through the `fs/*` event gate (no service) |
-| provider contract | `@deepseek-ai/dsh-fs` (this) | `ctx.fs`: execution-world paths, text IO, and atomic mutation primitives (optional version guard); owns the `fs/*` event vocabulary |
-| provider | `@deepseek-ai/dsh-fs-local` | the host-filesystem implementation |

+<a id="use-this-package"></a>
+## Use this package
 
-| Member | Semantics |
+You rarely load `dsh-fs` directly: you mount a backend that registers as `ctx.fs`, then either call the service from your own plugin or let the `dsh-tool-fs` tools call it for you. This page serves the two audiences that do touch it — deployments choosing a backend, and developers implementing or consuming the contract.
+
+### Choosing and mounting a backend
+
+Pick [`fs-local`](../fs-local/README.md) for ordinary host files, [`fs-sandbox`](../fs-sandbox/README.md) when a session's mutations must be confined to its workspace and temp roots, and [`fs-e2b`](../../e2b/fs-e2b/README.md) when file state must live in a remote execution world. Mounting any backend populates `ctx.fs`; swapping backends changes nothing for the policy plugin, the tools, or the tool schemas. A composition that mounts no backend has no `ctx.fs` at all, and the tools fail at registration.
+
+### What the service lets you do
+
+Through `ctx.fs` you can resolve any path to a stable target identity, read a whole text file or stream it in chunks, read raw bytes up to an explicit cap, list one directory level, atomically create or replace a file, and apply a literal text edit atomically. The version guard on both mutations is optional: omit it for unconditional create-or-overwrite, or supply it to fail when the file changed since you last observed it. Every operation returns data or a typed `FsError` carrying a stable code such as `FS_NOT_FOUND`, `FS_STALE_VERSION`, or `FS_AMBIGUOUS_EDIT`, so callers branch on the code, never on message text.

+
+### Design philosophy
+
+The contract is built on one separation and three commitments:
+
+- **Contract over mechanism.** The service names what a storage layer can do — resolve, stat, read, list, write, edit — and never how it stores bytes. Backends own target identity, execution-world coordinates, decoding, binary rejection, and atomicity.
+- **Policy stays off the base class.** Observed-state, read-before-edit, and version-guarded mutations are a plugin's job (`dsh-fs-observation-policy`), added by supplying the optional guard — so a sandboxed or remote backend inherits no model-facing observation policy.
+- **`editText` stays on the seam.** Version check, literal match, and atomic rewrite share one critical section, so error attribution and one-wins/one-stale concurrency stay correct; a remote backend may implement it as a native compare-and-edit.
+- **Bounds live at this seam.** `readBytes` requires `maxBytes` and fails with `FS_TOO_LARGE` rather than truncating, so no backend ever buffers an unbounded file.
+
+### Source map
+
+| File | Role |
 |---|---|
-| `resolve(path, opts?)` | Resolve a path into a stable `FsTarget` (opaque `targetKey`, `displayPath`). `opts.cwd` is the base a relative `path` resolves against (a caller supplies its session workspace; absolute paths ignore it; omitted ⇒ the backend default), while `opts.signal` aborts a backend round-trip. Async — a remote backend may need I/O. The same file via different paths must yield the same `targetKey`. |
-| `processPath(target)` | Return the canonical absolute path that a subprocess in this provider's execution world can open. This is intentionally distinct from opaque `targetKey`. |
-| `processPathFromHostPath(hostPath)` | Return this execution world's process path for the same absolute host file when the backend shares it. The base implementation returns `undefined`; host-backed or explicitly mapped backends override it. |
-| `fileUrl(target)` | Return the canonical `file:` URI in the execution world's platform syntax. The backend, not the host process, owns encoding. |
-| `contains(parent, child)` | Test canonical identity/descendant containment without exposing or parsing target keys. Both targets come from this provider. |
-| `stat(target, signal?)` | Return `FsInfo` metadata (`version`, `type`, optional `size`), or `undefined` when the target is absent. Never content. |
-| `lstat(path, opts?, signal?)` | Return `FsPathInfo` metadata without following the final path component when it is a symlink. This is path-shaped so consumers can reject repository-owned symlinks before `resolve` follows them into a target. |
-| `readText(target, signal?)` | Read the whole regular text file as one decoded string. Owns regular-file checks, UTF-8 decoding, binary/NUL rejection (`FS_NOT_TEXT`). |
-| `streamText(target, signal?)` | Stream the same text as decoded chunks for large files (cross-chunk UTF-8 decoding stays here); consumers that need a byte ceiling enforce it while consuming the stream. |
-| `readBytes(target, signal, maxBytes)` | Read a complete regular file as raw bytes with no decoding or binary rejection. `maxBytes` is required and bounds the complete content at this seam: a known or discovered overflow fails with `FS_TOO_LARGE` instead of truncating or buffering without a bound. |
-| `listDir(target, signal?)` | List direct directory children in stable name order. Returns entry names, entry types, resolved child targets, and cheap metadata (`version`/file `size` when available); never reads file contents. Missing targets throw `FS_NOT_FOUND`, non-directories throw `FS_NOT_DIRECTORY`, permission failures throw `FS_PERMISSION_DENIED`, and other backend I/O failures throw `FS_IO_ERROR`. Broken/disappeared children may be returned as `other` without metadata; child permission/IO failures fail the whole listing with the same structured codes. |
-| `writeText(target, content, expected?, signal?)` | Atomic create/replace. `expected` is OPTIONAL: omit ⇒ unconditional create-or-overwrite; supply an `FsWriteIntent` (`createIfAbsent`/`replaceIfVersion`) to guard. `createIfAbsent` must perform a no-replace publication so a creator racing the initial probe is preserved. |
-| `editText(target, edit, expected?, signal?)` | Literal edit. `expected` is OPTIONAL: omit ⇒ unconditional edit of the current content; supply `{ version }` to guard (verified BEFORE matching). A missing target reports `FS_STALE_VERSION` either way. Applies and writes atomically — one mutation critical section. |
+| [`src/index.ts`](src/index.ts) | Service definition: the abstract `FileSystem` class, the `ctx.fs` declaration, and the `fs/*` event vocabulary |
+| [`src/types.ts`](src/types.ts) | Vocabulary: `FsTarget`/`FsTargetKey`, `FsVersion`, `FsObservation`, `FsWriteIntent`, `FsError` and its codes |
 
-The mutation runs inside the backend's per-target lock either way, so an unconditional write/edit is still atomic — "unconditional" drops the *version* precondition, not the atomicity.
+### How a call flows
 
-## The `fs/*` policy events
+Every ordinary operation starts with `resolve(path, { cwd })`, which produces a stable `FsTarget` (an opaque `targetKey` plus a `displayPath` for model/UI output); the same file reached through different paths yields the same key. `processPathFromHostPath(hostPath)` separately maps an absolute host file into this execution world when the backend shares or explicitly maps it, and otherwise returns `undefined`. Reads then go `stat` → `readText`/`streamText`/`readBytes`, listings go `listDir`, and mutations go through one per-target critical section: the optional guard is checked, the new content is applied, and the result is published atomically.
 
-This package declares three events (see the generated region of [filesystem.md](../../../docs/subsystems/filesystem.md#cordis-surface)) so the emitter (`@deepseek-ai/dsh-tool-fs`) and the policy listener (`@deepseek-ai/dsh-fs-observation-policy`) share a vocabulary without the emitter depending on the policy plugin. `fs/write-intent` and `fs/edit-intent` are single-slot decision waterfalls (the listener fully decides, never calling `next()`); `fs/observed` is a fire-and-forget recording event carrying an `FsObservation` discriminated union: present with a version or confirmed absent. They carry only `dsh-fs` vocabulary plus an opaque `object` actor — no model-facing concepts and no agent/session owner structure.
+### The `fs/*` policy events
 
-## A provider contract, not the policy layer
+The package declares three events so the emitter (`dsh-tool-fs`) and the policy listener (`dsh-fs-observation-policy`) share a vocabulary without the emitter depending on the policy plugin. `fs/write-intent` and `fs/edit-intent` are single-slot decision waterfalls: the first listener decides outright and never calls `next()`. `fs/observed` is a fire-and-forget recording event carrying an `FsObservation` — present with a version, or confirmed absent. The events carry only `dsh-fs` vocabulary plus an opaque `object` actor.
 
-`ctx.fs` is deliberately close to fsspec-style storage primitives — half a level above byte-level `cat`/`open`, because it decodes text and rejects binaries so the policy layer never touches raw bytes. It owns UTF-8 decoding, binary rejection, atomic writes, and the literal-edit critical section. It does **not** own line windows, numbered lines, rendered footers, or observed-state. Observed-state, read-before-edit, and version-guarded write/edit are policy a plugin (`@deepseek-ai/dsh-fs-observation-policy`) ADDS by supplying the optional guard — not provider behavior — so a sandboxed/remote backend inherits no model-facing observation policy.
+### Invariants
 
-`editText` stays on this seam (not composed in the policy layer from a read plus a write) because version guard + literal match + atomic rewrite must stay inside one critical section for correct error attribution and one-wins/one-stale concurrency, and a remote backend may implement it as a native compare-and-edit.
+- `targetKey` and `version` are branded opaque ids: consumers must not parse or interpret them; only `displayPath` is for model/UI output.
+- Failures are typed `FsError`s with stable codes, never ad-hoc message strings.
+- The seam arms no I/O deadline; cancellation is an optional per-primitive `AbortSignal`.
 
-## Vocabulary
+</details>
 
-`FsTargetKey` / `FsVersion` are branded opaque ids ([the branded-ids Agent Note](../../../.agents/notes/implemented/architecture/2026-06-20-branded-ids.md)) — consumers must not parse `targetKey` or interpret `version`; only `displayPath` is for model/UI output. `FsObservation` distinguishes `{ kind: 'present', version }` from `{ kind: 'absent' }`, so a policy can separate an unseen target from confirmed absence without performing I/O. `FsWriteIntent` is the explicit GUARDED write intent (`createIfAbsent` creates a missing target and rejects an existing one with `FS_NOT_OBSERVED`; `replaceIfVersion` replaces only at the observed version, else `FS_STALE_VERSION`); omitting it from `writeText` is the third, unconditional state. `FsPathInfo` is the no-follow metadata shape that can report `symlink`, unlike target-level `FsInfo`. Failures throw `FsError` (extends `HarnessError`, [the structured error taxonomy Agent Note](../../../.agents/notes/implemented/architecture/2026-06-11-structured-error-taxonomy.md)) carrying a stable `FsErrorCode` (`FS_NOT_FOUND`, `FS_NOT_DIRECTORY`, `FS_NOT_TEXT`, `FS_NOT_REGULAR_FILE`, `FS_TOO_LARGE`, `FS_PERMISSION_DENIED`, `FS_IO_ERROR`, `FS_STALE_VERSION`, `FS_NOT_OBSERVED`, `FS_AMBIGUOUS_EDIT`, `FS_EDIT_NOT_FOUND`, `FS_ABORTED`); the tool registry exposes `{ name, code }` on `isError` results. See `src/types.ts` for the full contracts.

-**`FileSystem`**（`ctx.fs`）定义同一个执行世界中的存储原语，包括解析路径、公开规范化进程路径与文件 URI、映射共享的宿主文件、检查包含关系、完整或流式读取文本、有界读取原始字节、检查或列出元数据、原子写入和应用字面量编辑，但不规定实现方式。两个变更操作都**可选**接收版本防护，因此 `ctx.fs` 本身就是完整且不受约束的存储 seam。本包还拥有由工具分派、政策插件监听的 `fs/*` 政策事件词汇。
+## 概述
 
-本包拥有四层文件系统栈中的 Service Definition 和提供方约定层；该拆分使每个关注点可以独立演进和替换（见[能力 seam Agent Note](../../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.zh.md)、[文件系统能力 seam Agent Note](../../../.agents/notes/implemented/architecture/2026-06-17-filesystem-capability-seam.zh.md)、[拆分文件系统 seam Agent Note](../../../.agents/notes/implemented/simplification/2026-06-26-fsspec-style-fs-seam.zh.md)和[文件上下文事件门禁 Agent Note](../../../.agents/notes/implemented/architecture/2026-06-26-file-context-as-event-gate.zh.md)）：
+`dsh-fs` 定义 `ctx.fs` 文件系统服务：一个紧凑、与后端无关的约定，面向同一个执行世界，把路径解析为稳定身份、在受支持时映射共享宿主文件、在界内读取文本与原始字节、列出目录，并原子地执行写入与字面量编辑。它有意把存储机制留给实现它的后端——`fs-local` 面向宿主文件系统，`fs-sandbox` 面向策略强制的隔离，`fs-e2b` 面向远程执行世界。两个变更操作都带可选版本防护，因此即使不加载策略插件，挂载的后端依然提供完整、不受约束、原子的文件操作。本包还拥有由工具包分派、策略插件决策的 `fs/*` 策略事件词汇。当你需要可替换的文件系统表面时选择它；面向模型的工具本身位于 `dsh-tool-fs`。
 
-| 层 | 包 | 角色 |
-|---|---|---|
-| 工具/执行器 | `@deepseek-ai/dsh-tool-fs` | 面向模型的 `read`/`write`/`edit` schema、读取窗口和文本渲染；通过 `ctx.fs` 读取/写入/编辑，并分派 `fs/*` 事件 |
-| 政策 | `@deepseek-ai/dsh-fs-observation-policy` | 已观察状态、编辑前读取和版本防护的写入/编辑，通过 `fs/*` 事件门禁贡献（无服务） |
-| 提供方约定 | `@deepseek-ai/dsh-fs`（本包） | `ctx.fs`：执行世界路径、文本 I/O 与原子变更原语（可选版本防护）；拥有 `fs/*` 事件词汇 |
-| 提供方 | `@deepseek-ai/dsh-fs-local` | 宿主文件系统实现 |
+## 目录
 
-`fs-sandbox` 与 `fs-e2b` 实现该接口，无需更改政策层和工具层。

-## 服务 API（`ctx.fs`）
+-----
 
-后端继承 `FileSystem` 并公开十三个原语。
+<a id="use-this-package"></a>
+## 使用本包
 
-| 成员 | 语义 |
+你很少直接加载 `dsh-fs`：你挂载一个注册为 `ctx.fs` 的后端，然后从自己的插件调用该服务，或让 `dsh-tool-fs` 工具替你调用。本页服务于确实接触它的两类读者——选择后端的部署方，以及实现或消费该约定的开发者。
+
+### 选择并挂载后端
+
+普通宿主文件选择 [`fs-local`](../fs-local/README.zh.md)，会话变更必须限制在工作区与临时根目录内时选择 [`fs-sandbox`](../fs-sandbox/README.zh.md)，文件状态必须位于远程执行世界时选择 [`fs-e2b`](../../e2b/fs-e2b/README.zh.md)。挂载任一后端都会填充 `ctx.fs`；更换后端不会改变策略插件、工具或工具 schema。未挂载任何后端的组合就没有 `ctx.fs`，工具会在注册时失败。
+
+### 服务能做什么
+
+通过 `ctx.fs`，你可以把任意路径解析为稳定的目标身份、完整读取或分片流式读取文本文件、按显式上限读取原始字节、列出一层目录、原子地创建或替换文件，并原子地应用字面量文本编辑。两个变更操作上的版本防护都是可选的：省略它即无条件创建或覆盖，提供它则在文件自上次观察以来发生变化时失败。每个操作要么返回数据，要么抛出携带稳定错误码（如 `FS_NOT_FOUND`、`FS_STALE_VERSION`、`FS_AMBIGUOUS_EDIT`）的类型化 `FsError`，调用方依据错误码分支，绝不解析消息文本。

+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释约定背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+该约定建立在一个分离与三项承诺之上：
+
+- **约定高于机制。** 服务只命名存储层能做什么——解析、stat、读取、列出、写入、编辑——绝不规定如何存储字节。后端拥有目标身份、执行世界坐标、解码、二进制拒绝与原子性。
+- **策略不放在基类上。** 已观察状态、编辑前读取与版本防护的变更是插件（`dsh-fs-observation-policy`）的职责，通过提供可选防护来添加——因此沙箱化或远程后端不会继承任何面向模型的观察策略。
+- **`editText` 留在 seam 上。** 版本校验、字面量匹配与原子重写共享同一个临界区，错误归因与一方胜出/一方陈旧的并发语义因此保持正确；远程后端也可以将其实现为原生比较并编辑操作。
+- **界限制在此 seam 上。** `readBytes` 要求 `maxBytes`，并以 `FS_TOO_LARGE` 失败而不是截断，因此任何后端都不会无界缓冲文件。
+
+### 源码地图
+
+| 文件 | 职责 |
 |---|---|
-| `resolve(path, opts?)` | 把路径解析为稳定的 `FsTarget`（不透明 `targetKey`、`displayPath`）。`opts.cwd` 是相对 `path` 解析所依据的基准（调用方提供其会话工作区；绝对路径忽略该值；省略时使用后端默认值），`opts.signal` 则中止后端往返。该方法是异步的，因为远程后端可能需要 I/O。经不同路径到达的同一文件必须产生相同 `targetKey`。 |
-| `processPath(target)` | 返回该提供方执行世界中的子进程可以打开的规范化绝对路径。该路径有意与不透明的 `targetKey` 分离。 |
-| `processPathFromHostPath(hostPath)` | 当后端共享同一个宿主文件时，返回该文件在当前执行世界中的进程路径。基类返回 `undefined`，宿主后端或显式映射宿主文件的后端负责覆盖。 |
-| `fileUrl(target)` | 返回采用执行世界平台语法的规范化 `file:` URI。编码由后端而非宿主进程负责。 |
-| `contains(parent, child)` | 在不公开或解析目标 key 的情况下，检查规范化身份相等或后代包含关系。两个目标都来自该提供方。 |
-| `stat(target, signal?)` | 返回 `FsInfo` 元数据（`version`、`type`、可选 `size`）；目标不存在时返回 `undefined`。绝不返回内容。 |
-| `lstat(path, opts?, signal?)` | 当最后一个路径组件是符号链接时，不跟随该组件，返回 `FsPathInfo` 元数据。该方法采用路径形态，使消费方能在 `resolve` 跟随仓库所有的符号链接进入目标前拒绝它。 |
-| `readText(target, signal?)` | 把整个普通文本文件读取为一个解码后的字符串。负责普通文件检查、UTF-8 解码和二进制/NUL 拒绝（`FS_NOT_TEXT`）。 |
-| `streamText(target, signal?)` | 为大文件按解码后的分片流式读取相同文本（跨分片 UTF-8 解码仍由此处负责）；需要字节上限的消费方在消费流时执行该上限。 |
-| `readBytes(target, signal, maxBytes)` | 把完整普通文件按原始字节读出，不做解码或二进制拒绝。`maxBytes` 为必填，在该 seam 上限制完整内容：已知或读取中发现的超限以 `FS_TOO_LARGE` 失败，而不是截断或无界缓冲。 |
-| `listDir(target, signal?)` | 按稳定名称顺序列出直接子项。返回条目名称、条目类型、解析后的子目标和低成本元数据（若可用则包括 `version`/文件 `size`）；绝不读取文件内容。缺失目标抛出 `FS_NOT_FOUND`，非目录抛出 `FS_NOT_DIRECTORY`，权限失败抛出 `FS_PERMISSION_DENIED`，其他后端 I/O 失败抛出 `FS_IO_ERROR`。损坏/消失的子项可以作为无元数据的 `other` 返回；子项权限/I/O 失败会使用相同结构化代码使整个列表失败。 |
-| `writeText(target, content, expected?, signal?)` | 原子创建/替换。`expected` 是可选的：省略 ⇒ 无条件创建或覆盖；提供 `FsWriteIntent`（`createIfAbsent`/`replaceIfVersion`）⇒ 添加防护。`createIfAbsent` 必须以不替换的方式发布，使初始探测后抢先创建的文件得到保留。 |
-| `editText(target, edit, expected?, signal?)` | 字面量编辑。`expected` 是可选的：省略 ⇒ 无条件编辑当前内容；提供 `{ version }` ⇒ 添加防护，并在匹配之前校验。无论哪种情况，目标缺失都报告 `FS_STALE_VERSION`。应用和写入以原子方式完成，使用同一个变更临界区。 |
+| [`src/index.ts`](src/index.ts) | 服务定义：抽象 `FileSystem` 类、`ctx.fs` 声明与 `fs/*` 事件词汇 |
+| [`src/types.ts`](src/types.ts) | 词汇：`FsTarget`/`FsTargetKey`、`FsVersion`、`FsObservation`、`FsWriteIntent`、`FsError` 及其错误码 |
 
-无论是否有版本防护，变更都在后端的每目标锁内运行，因此无条件写入/编辑仍是原子的；「无条件」只移除*版本*前置条件，不移除原子性。
+### 调用流程
 
-## `fs/*` 政策事件
+每个普通操作都以 `resolve(path, { cwd })` 开始，它产生稳定的 `FsTarget`（不透明 `targetKey` 加用于模型/UI 输出的 `displayPath`）；经不同路径到达同一文件会产生相同 key。`processPathFromHostPath(hostPath)` 在后端共享或显式映射宿主文件时，单独把绝对宿主文件映射进此执行世界，否则返回 `undefined`。读取随后执行 `stat` → `readText`/`streamText`/`readBytes`，列出执行 `listDir`，变更则经过每个目标一个临界区：先检查可选防护，应用新内容，再原子发布结果。
 
-本包声明三个事件（见 [filesystem.md](../../../docs/subsystems/filesystem.zh.md#cordis-surface) 的生成区块），使发出方（`@deepseek-ai/dsh-tool-fs`）和政策监听器（`@deepseek-ai/dsh-fs-observation-policy`）共享词汇，而无需让发出方依赖政策插件。`fs/write-intent` 和 `fs/edit-intent` 是单槽决策 waterfall（瀑布式事件）（监听器完整决策，绝不调用 `next()`）；`fs/observed` 是发后即忘的记录事件，携带 `FsObservation` 可辨识联合：存在并带有版本，或确认缺失。它们只携带 `dsh-fs` 词汇和一个不透明 `object` 参与者，不含面向模型的概念或 agent（智能体）/会话所有者结构。

-`ctx.fs` 有意接近 fsspec 风格的存储原语，比字节级 `cat`/`open` 高半层，因为它会解码文本并拒绝二进制，使政策层绝不接触原始字节。它负责 UTF-8 解码、二进制拒绝、原子写入和字面量编辑临界区。它**不** 负责行窗口、编号行、渲染 footer 或已观察状态。已观察状态、编辑前读取和版本防护的写入/编辑属于插件（`@deepseek-ai/dsh-fs-observation-policy`）通过提供可选防护而添加的政策，并非提供方行为，因此沙箱化/远程后端不会继承任何面向模型的观察政策。

-`editText` 留在该 seam 上，不由政策层通过读取加写入组合，因为版本防护、字面量匹配和原子重写必须处于同一临界区内，才能正确归因错误并实现一方胜出/一方陈旧的并发；远程后端也可以将其实现为原生比较并编辑操作。

 # @deepseek-ai/dsh-tool-fs-search
 
 English | [中文](README.zh.md)
 
-The **model-facing filesystem discovery tools**—`glob`, `grep`—are backed by a packaged ripgrep binary, not by `ctx.fs` provider methods and not by a system `rg` install. Ordinary Node deployments resolve the platform binary from `@vscode/ripgrep`; a pkg single-file runtime resolves the executable's co-located `-rg` sidecar and falls back to the dependency binary when that sidecar is absent. Registration is unconditional because both carriers package ripgrep, so there is no load-time availability probe. Each call spawns the resolved binary through the `ctx.subprocess` seam with a fixed argv vector (`--no-config` prepended so a host `RIPGREP_CONFIG_PATH` cannot inject a `--pre` preprocessor into the unconfined spawn; model-controlled values are plain argv elements — no shell layer exists, so no quoting applies), parses the raw `rg` output, and returns a workdir-relative canonical value. The package injects `tools`, `systemPrompt`, and `subprocess`—deliberately **not** `fs`; `ctx.spillStore` is read opportunistically with `ctx.get()` because formatted-result spill is optional.
+## Summary
 
-```ts ignore-check

-await ctx.plugin(LocalSubprocessRuntime)                     // @deepseek-ai/dsh-subprocess-local

+`dsh-tool-fs-search` provides the model-facing filesystem discovery tools — `glob` and `grep` — backed by a packaged ripgrep binary, so no host `rg` install and no filesystem backend are needed. Each call runs ripgrep itself with a fixed argument set and returns workdir-relative results, and the tools are always available because every carrier packages ripgrep. Results are bounded by configurable caps, and a capped result is saved in full through the optional spill store when one is mounted. Choose this package when the model should discover files by pattern or search file contents; text file reading, writing, and editing are the sibling `dsh-tool-fs` package's job.

+## Use this package
+
+Mount the tools after a `ctx.subprocess` backend; no host `rg` install is needed, and no filesystem provider is required. The model then gets modification-time-ordered file discovery and line-oriented content search, each bounded and timeout-guarded.
+
+### Minimal composition
+
+A subprocess backend, then the tools; the spill backend is optional and makes capped results fully recoverable.
+
+```yaml
+- name: '@deepseek-ai/dsh-subprocess-local'
+- name: '@deepseek-ai/dsh-tool-fs-search'
+  config:
+    sampleOverCapGlobResults: false
+- name: '@deepseek-ai/dsh-spill-local'
 ```
 
-Why spawn-backed: local workspace discovery is naturally a process-backed `rg` workflow, and putting search on `ctx.fs` would force every filesystem backend to grow a search API. The subprocess seam owns spawn execution, process-tree termination, environment scrubbing, and bounded output capture; this package owns schemas, argument validation, argv construction, parsing, retention, formatted-result spill, and timeout declaration. The tools never expose a background job — the call returns only after `rg` exits, is terminated by the cooperative timeout, is aborted, or fails.
+`sampleOverCapGlobResults` is required and has no fallback: deployments choose the over-cap ordering contract explicitly. When formatted spill succeeds, both modes preserve the complete sorted list in the spill artifact.
 
-## Deployment requirement: no host rg, co-located workdir/filesystem
-
-Node deployments receive the `@vscode/ripgrep` platform package on supported macOS, Linux, and Windows x64/arm64 targets. Python SDK Linux and macOS wheels copy the target-native binary beside the single-file runtime as `<runtime>-rg`; `deepseek_harness_runtime.bundled_runtime_path()` rejects an incomplete wheel before launch. No carrier requires a host `rg` install. Returned paths are displayed relative to the resolved workdir (the calling agent's session cwd when present, else `process.cwd()`) and are follow-up-readable with `read` only when that workdir and the filesystem root are the same workspace. That co-location requirement carries no runtime cross-service validation; remote or virtual filesystem search waits for a shared workspace contract or a provider-specific search backend.
-
-## Config
-
-`sampleOverCapGlobResults` is required and has no fallback; deployments choose the over-cap ordering contract explicitly. The remaining keys are optional search caps with the defaults below.
-
-| Key | Default | Meaning |
-|---|---|---|
-| `sampleOverCapGlobResults` | none (required) | `true` samples an over-cap `glob` page across top-level entries; `false` keeps the modification-time-ordered head. When formatted spill succeeds, both modes preserve the complete sorted list in that artifact. |
-| `globMaxResults` | `100` | Max paths one `glob` call shows inline (matches Claude Code's `GlobTool` limit). A result within the cap remains complete and modification-time ordered. |
-| `grepMaxMatches` | `250` | Max flat matches one `grep` call retains inline (matches Claude Code's `GrepTool` `head_limit`); later matches go to the formatted spill artifact. |
-| `grepMaxLineBytes` | `2000` | Byte cap per matched-line preview; the cut preserves UTF-8 boundaries and is marked `(line truncated)`. |
-| `rawOutputMaxBytes` | `20000000` | Max complete raw `rg` stdout a search will parse (matches Claude Code's ripgrep raw buffer); larger raw output fails with `SEARCH_RAW_OUTPUT_OVERFLOW`. |
-| `timeoutMs` | `30000` | Cooperative tool-call budget attached to both tool definitions, enforced by `@deepseek-ai/dsh-tool-call-timeout-policy` through `exec.signal`; the subprocess seam's terminate escalation is the hard kill. |
-| `graceMs` | `3000` | Positive terminate-escalation grace the subprocess seam grants past `timeoutMs` before the search fails as `SEARCH_ABORTED`; it cannot exceed [`MAX_TIMER_DELAY_MS`](../../util/timeout/README.md). |
-| `stderrMaxBytes` | `65536` | Diagnostic-tail budget for `rg` stderr, captured through the subprocess seam's collect disposition; a lossy read keeps only the tail (marked `[stderr truncated]`). |
-
-## Tools
+### The tools
 
 | Tool | Arguments | Behavior |
 |---|---|---|
-| `glob` | `pattern`, `path?` | `rg --files --glob <pattern> --sort=modified --no-ignore --hidden` plus VCS metadata excludes (`.git`, `.svn`, `.hg`, `.bzr`, `.jj`, `.sl`). `path` is an optional **directory** search root; omitted means the resolved workdir. Returns one FILE path per line; `rg --files` never emits directory entries. The pattern keeps ripgrep semantics: without a `/` it matches the basename at any depth, so `*` matches the whole tree. Complete results stay modification-time ordered; over-cap presentation follows `sampleOverCapGlobResults`. |
-| `grep` | `pattern`, `path?`, `include?` | Line-oriented `rg --json` parse (no colon-splitting ambiguity). `pattern` is a ripgrep regex; `path` is an optional **file or directory** target; `include` is ONE positive glob filter — a comma-separated list or a negated (`!…`) value is rejected up front (brace alternation like `*.{ts,tsx}` is fine). Returns matches grouped by file as `Line N: <preview>`. |
+| `glob` | `pattern`, `path?` | Finds files whose paths match a glob pattern, including hidden and ignored files but excluding VCS metadata; a pattern with no `/` matches basenames at any depth, so `*` matches the whole tree; complete results stay modification-time ordered |
+| `grep` | `pattern`, `path?`, `include?` | Searches file contents with a ripgrep regex and returns matches grouped by file as `Line N: <preview>`; `include` is one positive glob filter, with comma-separated lists and negated values rejected up front |
 
-Routine budgets stay out of the model-facing schema (no `head_limit`/`offset`/`case_insensitive`/output modes): a model that needs surrounding context reads the matched file with `read`; one that needs later results follows the returned spill locator's retrieval hint.
+Routine budgets stay out of the model-facing schema: a model that needs surrounding context reads the matched file with `read`, and one that needs later results follows the returned spill locator's retrieval hint.
 
-## Two budgets, two artifacts
+### Configuration
 
-Raw `rg` stdout and stderr are internal transport details. Each search requests collect-mode budgets from the subprocess seam — complete stdout within `rawOutputMaxBytes` and a `stderrMaxBytes` diagnostic tail — with no spill files on either stream (the tool never reads a raw spill path). If the seam still reports a lossy stdout read, the search fails with `SEARCH_RAW_OUTPUT_OVERFLOW` and tells the model to narrow the query; a lossy stderr read only marks the diagnostic excerpt `[stderr truncated]`. A successful `glob` keeps the displayed search root and every acquired path in `{ root, paths }`; when sampling is enabled, `root` lets the Native renderer group an explicit relative or absolute search path by entries beneath that root rather than by its workdir prefix. `grep` keeps every acquired `{ path, lineNumber, line }` in `{ matches }`. Inline item and per-line preview caps apply only in the Native renderer. For a direct surface call with more logical results than the inline cap, post-policy best-effort saves the complete formatted preview through `ctx.spillStore.saveText()` and replaces only presentation with the configured page plus locator. Nested Code dispatches skip that spill because their full canonical value does not enter model context. Missing/failed spill keeps the inline page and reports that the complete result could not be saved—never an `isError`.
+`sampleOverCapGlobResults` is required; the remaining keys are optional search caps with the defaults below.
 
-## Errors
+| Key | Default | Meaning |

+| `rawOutputMaxBytes` | `20000000` | Max complete raw `rg` stdout a search will parse; larger raw output fails with `SEARCH_RAW_OUTPUT_OVERFLOW` |

+| `graceMs` | `3000` | Terminate-escalation grace the subprocess seam grants past `timeoutMs` |
+| `stderrMaxBytes` | `65536` | Diagnostic-tail budget for `rg` stderr |
+| `searchMetaMaxBytes` | `65536` | Max bytes of one search's serialized `presentationMeta`; trailing groups/paths drop past it |
 
-Search failures carry the package-owned `SearchError` (a `HarnessError` subclass), surfaced as `{ name, code }` on `isError` results: `SEARCH_INVALID_PATTERN` (ripgrep rejected the regex/glob), `SEARCH_FAILED` (a failed `rg` launch, inaccessible target, signal kill, malformed `--json` output), `SEARCH_RAW_OUTPUT_OVERFLOW` (raw output over `rawOutputMaxBytes`, or still lossy after the requested stdout capture budget), and `SEARCH_ABORTED` (cooperative tool timeout or caller cancellation). ripgrep exit semantics are tool-owned: exit 0 is success with results, exit 1 is a successful empty search (`No files found` / `No matches found`), and only other exits are failures. Model argument mistakes (blank pattern, a list-valued `include`) stay ordinary tool argument errors.

+### Deployment requirement
+
+Node deployments receive the `@vscode/ripgrep` platform package on supported macOS, Linux, and Windows targets; Python SDK wheels copy the target-native binary beside the single-file runtime as a `-rg` sidecar. No carrier requires a host `rg`. Returned paths are displayed relative to the resolved workdir (the calling session's cwd when present) and are follow-up-readable with `read` only when that workdir and the filesystem root are the same workspace.
+
+### Failures and recovery
+
+Search failures carry the package-owned codes `SEARCH_INVALID_PATTERN` (ripgrep rejected the regex or glob), `SEARCH_FAILED` (a failed launch, inaccessible target, signal kill, or malformed `--json` output), `SEARCH_RAW_OUTPUT_OVERFLOW` (raw output over the cap), and `SEARCH_ABORTED` (cooperative timeout or caller cancellation). Exit 0 is success with results and exit 1 is a successful empty search; model argument mistakes stay ordinary tool argument errors.

+## Understand the implementation

+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the search tools and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+Local workspace discovery is naturally a process-backed `rg` workflow, and putting search on `ctx.fs` would force every filesystem backend to grow a search API. The subprocess seam owns spawn execution, process-tree termination, environment scrubbing, and bounded output capture; this package owns schemas, argument validation, argv construction, parsing, retention, formatted-result spill, and timeout declaration. The tools never expose a background job — the call returns only after `rg` exits, is terminated by the cooperative timeout, is aborted, or fails.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `Config`, tool composition, cap validation |
+| [`src/glob.ts`](src/glob.ts) | `glob` schema, argv, parsing, inline sampling, formatting |
+| [`src/grep.ts`](src/grep.ts) | `grep` schema, argv, `--json` parsing, preview retention, formatting |
+| [`src/search-core.ts`](src/search-core.ts) | Shared spawn helper, `SEARCH_*` errors, spill handoff, workdir-relative display |
+| [`src/presentation.ts`](src/presentation.ts) | Search-card metadata projection |
+| [`src/direct-call.ts`](src/direct-call.ts) | Direct-call result acceptance for spill post-processing |
+
+### How a search runs
+
+Each call resolves the packaged binary (`@vscode/ripgrep`, or the executable's `-rg` sidecar in a pkg single-file runtime), prepends `--no-config` so a host `RIPGREP_CONFIG_PATH` cannot inject a `--pre` preprocessor into the unconfined spawn, and passes every model-controlled value as a plain argv element — no shell layer exists, so no quoting applies. Collect-mode budgets bound complete stdout and a stderr tail; a lossy stdout read fails as `SEARCH_RAW_OUTPUT_OVERFLOW` rather than parsing a silently-partial stream. The tools never read a raw spill path.
+
+### Two budgets, two artifacts
+
+Raw stdout and stderr are internal transport details; the tools always collect the complete result in memory, and only the inline page is capped. When a call yields more logical results than the inline cap, a best-effort spill saves the complete formatted preview to the spill store and the page carries its locator, while dispatches whose full value never enters model context skip the spill. Missing or failed spill keeps the inline page and reports that the complete result could not be saved — never an error. The collection and spill handoff live in `src/search-core.ts` and `src/presentation.ts`.

 - **Search and file access have no shared-workspace proof** — returned paths are follow-up-readable only when the workdir and filesystem root denote the same workspace; the package performs no runtime cross-service validation.
 - **The packaged binary is fixed at dependency version** — Node deployments use the version selected by `@vscode/ripgrep`; Python single-file runtimes copy that target-native version into the required `-rg` sidecar. An unsupported platform or a corrupted installation fails with `SEARCH_FAILED`, while the Python runtime package rejects a missing sidecar before launch. Remote or virtual filesystems need a co-located workspace or another search consumer.
 - **The schemas expose one bounded page** — offset pagination, case-mode switches, alternate output modes, and provider-backed discovery remain outside this package; capped complete output requires a spill backend.
-- **Sampling, when enabled, groups by first path segment beneath the search root only** — an over-cap `glob` page balances across those top-level entries, so a result concentrated deeper (one busy directory inside an otherwise even tree) is still shown unevenly below that level; recursive balancing is deferred.

-**面向模型的文件系统发现工具**（`glob`、`grep`）由打包的 ripgrep 二进制支持，而不是由 `ctx.fs` 提供方方法或系统 `rg` 安装支持。普通 Node 部署从 `@vscode/ripgrep` 解析平台二进制；pkg 单文件运行时解析与可执行程序共置的 `-rg` 伴随文件，伴随文件缺失时回退到依赖中的二进制。两种载体均打包 ripgrep，因此注册是无条件的，没有加载期可用性探针。每次调用都通过 `ctx.subprocess` seam 以固定 argv 向量 spawn 解析出的二进制（前缀 `--no-config`，使宿主的 `RIPGREP_CONFIG_PATH` 无法向不受约束的 spawn 注入 `--pre` 预处理器；模型控制的值是普通 argv 元素——不存在 shell 层，因此不涉及 shell 引号处理），解析原始 `rg` 输出，并返回相对于工作目录的规范值。本包注入 `tools`、`systemPrompt` 和 `subprocess`，有意**不**注入 `fs`；格式化结果 spill 为可选功能，因此机会性读取 `ctx.spillStore`，调用方式为 `ctx.get()`。
+## 概述

+`dsh-tool-fs-search` 提供面向模型的文件系统发现工具——`glob` 与 `grep`——由打包的 ripgrep 二进制支持，因此既不需要宿主 `rg` 安装，也不需要文件系统后端。每次调用都由 ripgrep 自身以固定参数集执行，并返回相对于工作目录的结果；由于每种载体都打包 ripgrep，工具始终可用。结果受可配置上限约束，达到上限的结果会在挂载可选 spill 存储时完整保存。当模型需要按模式发现文件或搜索文件内容时选择本包；文本文件的读取、写入与编辑是同级 `dsh-tool-fs` 包的职责。

-采用 spawn 支持的原因：本地工作区发现天然是由进程支持的 `rg` 工作流；如果把搜索放到 `ctx.fs` 上，就会迫使每个文件系统后端扩展搜索 API。subprocess seam 负责 spawn 执行、进程树终止、环境清理和有界输出捕获；本包负责 schema、参数校验、argv 构造、解析、保留、格式化结果 spill 和超时声明。工具绝不暴露后台任务——只有在 `rg` 退出、被协作式超时终止、被中止或失败后，调用才会返回。
+`sampleOverCapGlobResults` 是必填项且没有回退值：部署必须显式选择超过上限时的排序约定。格式化 spill 成功时，两种模式都会在 spill 产物中保留完整排序列表。

-Node 部署在受支持的 macOS、Linux 与 Windows x64/arm64 目标上获得 `@vscode/ripgrep` 平台包。Python SDK 的 Linux 与 macOS wheel 将目标原生二进制复制到单文件运行时旁，命名为 `<runtime>-rg`；`deepseek_harness_runtime.bundled_runtime_path()` 会在启动前拒绝不完整的 wheel。两种载体均不要求宿主安装 `rg`。返回路径会相对于解析后的工作目录显示（调用方 agent（智能体）有会话 cwd 时使用该 cwd，否则使用 `process.cwd()`）；只有该工作目录与文件系统根目录是同一工作区时，才能用 `read` 继续读取。这项共置要求不附带运行时跨服务校验；远程或虚拟文件系统搜索需等待共享工作区约定或特定提供方的搜索后端。

-## 配置
-
-`sampleOverCapGlobResults` 是必填项且没有回退值；部署必须显式选择超过上限时的排序约定。其余配置键是可选的搜索上限，默认值如下。
-
-| 配置键 | 默认值 | 含义 |
-|---|---|---|
-| `sampleOverCapGlobResults` | 无（必填） | `true` 会在顶层条目之间对超过上限的 `glob` 页面采样；`false` 保留按修改时间排序的前部。格式化 spill 成功时，两种模式都会在该产物中保留完整排序列表。 |
-| `globMaxResults` | `100` | 一次 `glob` 调用内联展示的最大路径数（与 Claude Code 的 `GlobTool` 上限相同）。未超过上限的结果保持完整，并按修改时间排序。 |
-| `grepMaxMatches` | `250` | 一次 `grep` 调用内联保留的最大平铺匹配数（与 Claude Code 的 `GrepTool` `head_limit` 相同）；后续匹配写入格式化 spill 产物。 |
-| `grepMaxLineBytes` | `2000` | 每条匹配行预览的字节上限；截断会保留 UTF-8 边界，并标记为 `(line truncated)`。 |
-| `rawOutputMaxBytes` | `20000000` | 搜索将解析的完整原始 `rg` stdout 上限（与 Claude Code 的 ripgrep 原始 buffer 相同）；更大的原始输出以 `SEARCH_RAW_OUTPUT_OVERFLOW` 失败。 |
-| `timeoutMs` | `30000` | 附加到两个工具定义上的协作式工具调用预算，由 `@deepseek-ai/dsh-tool-call-timeout-policy` 通过 `exec.signal` 强制执行；subprocess seam 的终止升级提供硬终止。 |
-| `graceMs` | `3000` | subprocess seam 在 `timeoutMs` 之外授予的终止升级宽限期须为正值；超过后搜索以 `SEARCH_ABORTED` 失败；该宽限期不得大于 [`MAX_TIMER_DELAY_MS`](../../util/timeout/README.zh.md)。 |
-| `stderrMaxBytes` | `65536` | `rg` stderr 的诊断尾部预算，经 subprocess seam 的 collect 形态捕获；lossy 读取只保留尾部（标记 `[stderr truncated]`）。 |

-| `grep` | `pattern`、`path?`、`include?` | 按行解析 `rg --json`，避免按冒号拆分的歧义。`pattern` 是 ripgrep 正则表达式；`path` 是可选的**文件或目录**目标；`include` 是一个正向 glob 过滤器，前置拒绝逗号分隔列表或否定值（`!…`），但允许 `*.{ts,tsx}` 等花括号交替。返回按文件分组、形如 `Line N: <preview>` 的匹配。 |

-## 两类预算、两类产物
+### 配置
 
-原始 `rg` stdout 与 stderr 是内部传输细节。每次搜索从 subprocess seam 请求 collect 模式预算——`rawOutputMaxBytes` 内的完整 stdout 与 `stderrMaxBytes` 的诊断尾部——两条流都不产生 spill 文件（工具从不读取原始 spill 路径）。如果 seam 仍报告 lossy stdout 读取，搜索会以 `SEARCH_RAW_OUTPUT_OVERFLOW` 失败，并要求模型缩小查询；lossy stderr 读取只把诊断摘录标记为 `[stderr truncated]`。成功的 `glob` 在 `{ root, paths }` 中保留所显示的搜索根及所有已取得路径；启用采样时，借助 `root`，Native 渲染器能以显式的相对或绝对搜索路径为根，按该根下的条目分组，而不是按其工作目录前缀分组。`grep` 保留所有已取得的 `{ path, lineNumber, line }`，并将其存入 `{ matches }`。内联条目和每行预览上限只应用于 Native 渲染器。直接接口调用的逻辑结果超过内联上限时，后置策略会尽力通过 `ctx.spillStore.saveText()` 保存完整格式化预览，并只把呈现替换为配置指定的页面与 locator。嵌套 Code 分派会跳过 spill，因为其完整规范值不会进入模型上下文。spill 缺失/失败时保留内联页面，并报告完整结果无法保存，绝不会成为 `isError`。

+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释搜索工具背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+本地工作区发现天然是由进程支持的 `rg` 工作流；如果把搜索放到 `ctx.fs` 上，就会迫使每个文件系统后端扩展搜索 API。subprocess seam 负责 spawn 执行、进程树终止、环境清理与有界输出捕获；本包负责 schema、参数校验、argv 构造、解析、保留、格式化结果 spill 与超时声明。工具绝不暴露后台任务——只有在 `rg` 退出、被协作式超时终止、被中止或失败后，调用才会返回。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：`Config`、工具组合、上限校验 |
+| [`src/glob.ts`](src/glob.ts) | `glob` schema、argv、解析、内联采样、格式化 |
+| [`src/grep.ts`](src/grep.ts) | `grep` schema、argv、`--json` 解析、预览保留、格式化 |
+| [`src/search-core.ts`](src/search-core.ts) | 共享 spawn 助手、`SEARCH_*` 错误、spill 交接、工作目录相对展示 |
+| [`src/presentation.ts`](src/presentation.ts) | 搜索卡片元数据投影 |
+| [`src/direct-call.ts`](src/direct-call.ts) | spill 后处理的直接调用结果接受 |
+
+### 搜索如何运行
+
+每次调用解析打包二进制（`@vscode/ripgrep`，或 pkg 单文件运行时中可执行程序的 `-rg` 伴随文件），前置 `--no-config`，使宿主的 `RIPGREP_CONFIG_PATH` 无法向不受约束的 spawn 注入 `--pre` 预处理器，并把每个模型控制的值作为普通 argv 元素传入——不存在 shell 层，因此不涉及 shell 引号处理。collect 模式预算限制完整 stdout 与 stderr 尾部；lossy stdout 读取以 `SEARCH_RAW_OUTPUT_OVERFLOW` 失败，而不是解析静默不完整的流。工具从不读取原始 spill 路径。
+
+### 两类预算、两类产物
+
+原始 stdout 与 stderr 是内部传输细节；工具始终把完整结果收集到内存中，只有内联页面设有上限。当调用产生超过内联上限的逻辑结果时，尽力而为的 spill 会把完整格式化预览保存到 spill 存储，页面携带其 locator；完整值不会进入模型上下文的分派则跳过 spill。spill 缺失或失败时保留内联页面，并报告完整结果无法保存——绝不会成为错误。收集与 spill 交接位于 `src/search-core.ts` 与 `src/presentation.ts`。

 # @deepseek-ai/dsh-tool-fs
 
 English | [中文](README.zh.md)
 
-The **model-facing filesystem tools** — `read`, `read_image`, `write`, `edit` — and their **executor**. This is the consumer layer of the filesystem stack: it owns tool names, JSON schemas, argument validation, prompt sections, **read windowing**, and result formatting. It reads/writes/edits through the `ctx.fs` provider contract ([`@deepseek-ai/dsh-fs`](../fs)) **directly**. The freshness/observation policy is contributed by a separate plugin ([`@deepseek-ai/dsh-fs-observation-policy`](../fs-observation-policy)) through the `fs/*` event gate; the tool is not method-coupled to it. Under a confining provider, the shared sandbox-policy service is required for per-session execution and the tool exposes escalation for filesystem mutations.
+## Summary
 
-```ts ignore-check
-// Default deployment: a ctx.fs provider, the policy plugin, then the tools.
-await ctx.plugin(LocalFileSystem, { cwd: process.cwd() }) // @deepseek-ai/dsh-fs-local
-await ctx.plugin(FsPolicy)                             // @deepseek-ai/dsh-fs-observation-policy (policy gate)
-await ctx.plugin(LocalAttachmentStore, { dshHome })       // optional — enables durable read_image results
-await ctx.plugin(ToolFs)                                  // this package — read/write/edit, plus read_image with attachments
+`dsh-tool-fs` provides the model-facing filesystem tools — `read`, `read_image`, `write`, and `edit` — and their executor. With them the model reads files with line numbers, creates or replaces them atomically, and applies targeted literal edits; results are capped and failures carry stable codes with recovery instructions, all backed by a mounted `ctx.fs` backend. The read-before-edit policy lives in a separate plugin (`dsh-fs-observation-policy`), so omitting it yields unconditional, still-atomic mutations. `read_image` appears while a durable attachment store is mounted and refuses execution unless the routed model declares image input. Choose this package when the model should read, create, replace, or edit UTF-8 text files; discovery (`glob`/`grep`) is a sibling package.

+## Use this package
+
+Mount the tools after a `ctx.fs` backend and, for read-before-write/edit behavior, the policy plugin. The model then gets line-numbered reads, atomic writes and edits, and — with an attachment store mounted — image reads; every result is capped, and failures carry stable codes with recovery instructions.
+
+### Minimal composition
+
+A backend, the policy plugin, then the tools; the attachment store is optional and enables `read_image`.

-`@deepseek-ai/dsh-fs-observation-policy` is **optional**: omit it and the tools run against the bare provider (unconditional write/overwrite/edit, no observed-state). A deployment that loads these tools is expected to also load it, so the behavior is read-before-write/edit.
+The policy plugin is optional: without it the tools run against the bare provider (unconditional write, overwrite, and edit with no observed-state). A deployment that loads these tools is expected to also load it, so the behavior is read-before-write/edit. `read_image` registers only while a durable `ctx.attachments` service is mounted; execution additionally refuses on a route whose exact model does not declare image input, so a text route's durable history stays free of image blocks.
 
-`read_image` registers only while a durable `ctx.attachments` service is mounted. Execution additionally requires the exact routed model to declare `image` input, resolved through `ctx.llm.resolveModelInfo` from the session's latest request header and then from agent options.
+### The tools
 
-## Config
+| Tool | Arguments | Behavior |
+|---|---|---|
+| `read` | `file_path`, `offset?`, `limit?` | Line-numbered UTF-8 content with a pagination footer; `offset` is 1-based and `limit` defaults to and caps at the configured `readLimit` |
+| `read_image` | `file_path` | Reads and persists a PNG/JPEG/WebP/GIF source; normalization can downscale it before the next model request, so the model need not create a thumbnail first |
+| `write` | `file_path`, `content` | Creates or fully replaces a file; with the policy plugin, overwriting requires a prior `read` at the unchanged version, creating does not |
+| `edit` | `file_path`, `old_string`, `new_string`, `replace_all?` | Literal replacement requiring a unique match unless `replace_all` is true; with the policy plugin, requires a prior `read` and an unchanged file |
+
+Field names are snake_case to match Claude Code and existing harness tool schemas. Successes return compact envelopes — a read window, an image reference, or a `Created file`/`Updated file` confirmation — and `write`/`edit` derive replayable diff-card metadata for UI presentation.
+
+### Configuration
 
 All keys are optional; the defaults are the shipped read caps.
 
 | Key | Default | Meaning |
 |---|---|---|
-| `readLimit` | `2000` | Default and maximum lines returned by one `read` call (the tool schema advertises it as the `limit` default). |
-| `readMaxLineLength` | `2000` | Characters kept per line before truncation (the suffix names the cap). |
-| `readMaxBytes` | `51200` | Byte cap on one `read` call's selected lines; overflow ends the window with a "capped" footer. |
-| `readStreamMinSize` | `10485760` | Files at or above this size (or with unknown size) stream instead of loading whole into memory. |
+| `readLimit` | `2000` | Default and maximum lines returned by one `read` call |

-## Tools (schemas per [the filesystem tool schemas Agent Note](../../../.agents/notes/implemented/feature/2026-06-17-filesystem-tool-schemas.md))
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-tool-fs) is the exhaustive source for every accepted field and its JSDoc.
 
-| Tool | Arguments | Behavior |
-|---|---|---|
-| `read` | `file_path`, `offset?`, `limit?` | Line-numbered UTF-8 content with a pagination footer. `offset` is 1-based; `limit` defaults to and caps at the configured `readLimit` (2000). |
-| `read_image` | `file_path` | Reads a PNG/JPEG/WebP/GIF file through the bounded byte seam, persists it through `ctx.attachments.saveImage`, and returns an image block beside a small metadata envelope. Harness validates and downscales large supported images before the next model request, so the model can read the source directly without first creating a thumbnail. It succeeds only when the exact routed model declares image input. |
-| `write` | `file_path`, `content` | Create or fully replace a file. With the policy plugin: overwriting an existing file requires a prior `read` at the unchanged version; creating a new file does not. Without it: unconditional. |
-| `edit` | `file_path`, non-empty `old_string`, `new_string`, `replace_all?` | Literal replacement; unique match required unless `replace_all` is true. With the policy plugin: requires a prior `read` (any window) and the file unchanged since. Without it: unconditional. |
+### Policy and sandbox behavior
 
-Field names are snake_case to match Claude Code and existing harness tool schemas.
+With the policy plugin mounted, `write` and `edit` obtain their guard from the `fs/*` intent slots, so an unread target or a stale observation fails with `FS_NOT_OBSERVED` or `FS_STALE_VERSION` and a recovery instruction. Under a confining backend (`fs-sandbox`), `write`/`edit` additionally advertise `sandbox_permissions` and `justification`; a denied mutation returns the `[sandbox: file access denied under <mode> mode]` marker with the same-turn escalation hint, and an approved retry may stamp a strictly wider mode for that one call.
 
-Structured successes are `read` → `{ path, offset, lines: [{ number, text }], totalLines }`, `read_image` → `{ path, image: { attachmentId, mediaType, bytes, width, height, name?, originalDimensions?: { width, height } } }`, `write` → `{ path, operation: 'create' | 'update', before: string | null, after }`, and `edit` → `{ path, before, after }`. `originalDimensions` appears only when normalization downscaled the submitted raster and records its orientation-applied input size. Native renderers preserve the line-numbered read and mutation acknowledgements below. `write`/`edit` derive replayable diff-card metadata, and `read` derives a replayable read-card window `{ path, offset, lines, totalLines, lang? }`; execution-local structured values are not added to `tool/result`, while image renderers emit the durable image blocks that the result logs.
+### Failures and recovery
 
-## The tool is the executor; policy is an event gate
+Failures are normalized as `Error: <message>` with a structured code preserved for callers. Stable messages include `file_path must be a non-empty string`, `limit must be less than or equal to <max>`, `cannot read "<path>": not found`, `cannot read "<path>": not a regular file`, and the image-route refusal `cannot read "<path>" as an image: model "<model>" does not declare image input; switch to an image-capable model to read images`. Guarded-mutation failures append their remedy: `FS_STALE_VERSION` gets `— re-read the file, then retry`, `FS_NOT_OBSERVED` gets `— read the file, then retry`. After the reread confirms absence, `edit` reports `FS_NOT_FOUND` instead of repeating a stale remedy, while `write` uses guarded creation.
 
-The tools do **not** inject a policy service or inspect any cache. Each tool resolves the path via `ctx.fs.resolve(path, { cwd, signal })` — passing the calling agent's session cwd (`exec.agent.session.header.cwd`) so a relative path resolves against the session's workspace, matching `dsh-tool-bash`, and forwarding tool cancellation through resolution (see [the per-session cwd Agent Note](../../../.agents/notes/implemented/architecture/2026-07-02-fs-per-session-cwd.md)) — then:

-- **read** — one `ctx.fs.stat` (type + size routing + version), then `readText`/`streamText`, then builds the line window, then emits `fs/observed` with a plain `ctx.emit`. (1 stat.)
-- **read_image** — validates the argument, extension, attachment availability, deployment media types, and the image-capable route before any I/O; then one `ctx.fs.stat` (recording an `absent` observation for a missing target, like `read`), a bounded `ctx.fs.readBytes` capped at the smaller of `imageLimits.maxImageBytes` and `imageLimits.maxMessageImageBytes` (the result is one message carrying one image), `attachments.saveImage` (content-addressed, so the image block references a durably committed object by the time `tool/result` is appended), and finally `fs/observed`. (1 stat.)
-- **write** — `ctx.waterfall('fs/write-intent', target, exec, () => undefined)` for the optional guard, then `ctx.fs.writeText(target, content, intent)`, then `fs/observed`. (0 stat.)
-- **edit** — `ctx.waterfall('fs/edit-intent', target, exec, () => undefined)` for the optional guard, then `ctx.fs.editText(target, edit, intent)`, then `fs/observed`. (0 stat.)

+## Understand the implementation
 
-The tool passes `exec` (the tool-execution context) as the opaque `actor` on every dispatch. The default thunks return `undefined` (the unconstrained bare provider). When `@deepseek-ai/dsh-fs-observation-policy` is loaded it occupies the single decision slot — returning `createIfAbsent`/`replaceIfVersion`/`{ version }` or throwing `FS_NOT_OBSERVED` — and records on `fs/observed`. Backend errors (`FsError`) and a thrown `FS_NOT_OBSERVED` flow through `ToolRuntime.execute()` and become `isError` tool results with their `{ name, code }` attached.
+<details>
+<summary>Implementation internals — click to expand</summary>
 
-When `ctx.fs.sandboxMode` reports confinement, write/edit advertise `sandbox_permissions` and `justification` and resolve approved retries through `ctx.approval`. The policy owner contributes capability-neutral standing policy; the tool results retain operation-specific denial and retry guidance.
+This section explains the design decisions behind the tool suite and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
 
-## `fs/observed` is fire-and-forget
+### Design concept
 
-`fs/observed` fires AFTER the read/read_image/write/edit already succeeded, via a plain `ctx.emit`. A listener is contractually a synchronous, side-effect-only recorder (`@deepseek-ai/dsh-fs-observation-policy`'s is a `WeakMap.set`); the tool does not guard the emit, so a listener that throws would surface as the tool's `isError` result — async or fallible observation does not belong on this event.
+The tools are the executor; policy is an event gate. The tools inject no policy service and inspect no cache — each mutation asks the single intent slot for its guard through `ctx.waterfall`, and each operation emits `fs/observed` only after it succeeded. Reads do exactly one provider `stat` (type and size routing plus the observed version); mutations do none, because the guard comes from the intent slot and the provider re-checks under its lock.
 
-`read` opts into concurrent scheduling because its only mutation is the synchronous version recorder. Recorder races fail closed when a later `write` or `edit` re-checks the version under its target lock; both mutation tools remain exclusive. See the [parallel tool-call Agent Note](../../../.agents/notes/implemented/feature/2026-07-10-parallel-tool-call-execution.md).
+### Source map
 
-The package root exports only the Cordis plugin contract (`name`, `inject`, `Config`, and `apply`). Read rendering (line windowing + output formatting) lives in `src/read-render.ts` (Cordis-free, independently unit-tested); `src/read.ts`/`read-image.ts`/`write.ts`/`edit.ts` are the tool executors and `src/index.ts` composes them.
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `Config`, tool composition, `read_image` attachments gate |
+| [`src/read.ts`](src/read.ts) | `read` executor: one stat, streaming decision, window build, observation |
+| [`src/read-image.ts`](src/read-image.ts) | `read_image` executor: route and media-type gates, bounded bytes, attachment save |
+| [`src/write.ts`](src/write.ts) | `write` executor: intent waterfall, atomic write, observation |
+| [`src/edit.ts`](src/edit.ts) | `edit` executor: intent waterfall, literal edit, observation |
+| [`src/read-render.ts`](src/read-render.ts) | Cordis-free windowing and envelope formatting |
+| [`src/sandbox.ts`](src/sandbox.ts) | Escalation API shared by `write`/`edit`: policy resolution and denial-marker mapping |
+| [`src/error.ts`](src/error.ts) | Model-facing remedy appended to `FS_STALE_VERSION` and `FS_NOT_OBSERVED` |
 
+### Per-tool flow
+
+All four tools share one flow shape: resolve the path with the calling session's cwd, run the applicable gate, perform exactly one provider operation, and emit `fs/observed` only after success. `read` and `read_image` pay one `stat` for type and size routing; `write` and `edit` pay none because their guard comes from the intent slot, and provider failures surface as typed `FsError` results. The per-tool executors live in `src/read.ts`, `src/read-image.ts`, `src/write.ts`, and `src/edit.ts`.
+
+### Observation and concurrency
+
+`fs/observed` fires after the operation succeeded via a plain `ctx.emit`; a listener is contractually a synchronous, side-effect-only recorder, so async or fallible observation does not belong on this event. `read` opts into concurrent scheduling because its only mutation is the synchronous version recorder; recorder races fail closed when a later `write` or `edit` re-checks the version under its target lock, and both mutation tools remain exclusive.

 # @deepseek-ai/dsh-tool-fs
 
 [English](README.md) | 中文
 
-**面向模型的文件系统工具**（`read`、`read_image`、`write`、`edit`）及其**执行器**。这是文件系统栈的消费方层：拥有工具名称、JSON Schema、参数校验、提示词段、**读取窗口逻辑**和结果格式化。它**直接**通过 `ctx.fs` 提供方约定（[`@deepseek-ai/dsh-fs`](../fs)）读取、写入和编辑。新鲜度与观察策略由独立插件（[`@deepseek-ai/dsh-fs-observation-policy`](../fs-observation-policy)）通过 `fs/*` 事件门禁贡献；工具不与其方法耦合。使用施加沙箱限制的提供方时，逐会话执行需要共享沙箱策略服务，工具还会为文件系统变更提供升权路径。
+## 概述
 
-```ts ignore-check
-// Default deployment: a ctx.fs provider, the policy plugin, then the tools.
-await ctx.plugin(LocalFileSystem, { cwd: process.cwd() }) // @deepseek-ai/dsh-fs-local
-await ctx.plugin(FsPolicy)                             // @deepseek-ai/dsh-fs-observation-policy (policy gate)
-await ctx.plugin(LocalAttachmentStore, { dshHome })       // optional — enables durable read_image results
-await ctx.plugin(ToolFs)                                  // this package — read/write/edit, plus read_image with attachments
+`dsh-tool-fs` 提供面向模型的文件系统工具——`read`、`read_image`、`write` 与 `edit`——及其执行器。借助它们，模型可以带行号读取文件、原子地创建或替换文件，并执行有针对性的字面量编辑；结果都有上限，失败携带稳定错误码与恢复指令，所有文件操作都运行在已挂载的 `ctx.fs` 后端之上。编辑前读取策略位于独立插件（`dsh-fs-observation-policy`）中，因此省略它只会得到无条件、依然原子的变更。`read_image` 在持久附件存储已挂载时出现，并且只在路由模型声明图片输入时允许执行。当模型需要读取、创建、替换或编辑 UTF-8 文本文件时选择本包；发现工具（`glob`/`grep`）在同级包中。

+## 使用本包
+
+在 `ctx.fs` 后端之后挂载工具，并在需要先读后写/编辑行为时挂载策略插件。模型随后获得带行号的读取、原子的写入与编辑，以及——挂载附件存储时——图像读取；每个结果都有上限，失败携带稳定错误码与恢复指令。
+
+### 最小组合
+
+一个后端、策略插件，然后是工具；附件存储为可选，用于启用 `read_image`。
+
+```yaml
+- name: '@deepseek-ai/dsh-fs-local'
+- name: '@deepseek-ai/dsh-fs-observation-policy'
+- name: '@deepseek-ai/dsh-tool-fs'
 ```
 
-`@deepseek-ai/dsh-fs-observation-policy` 是**可选的**：省略时，工具直接使用裸提供方（无条件写入/覆盖/编辑，无已观察状态）。加载这些工具的部署也应加载该插件，从而提供写入/编辑前读取行为。
+策略插件是可选的：省略时，工具直接使用裸提供方（无条件写入、覆盖与编辑，无已观察状态）。加载这些工具的部署也应加载该插件，从而提供写入/编辑前读取行为。`read_image` 只在持久 `ctx.attachments` 服务已挂载时注册；执行时还拒绝确切模型未声明图像输入的路由，因此文本路由的持久历史不会出现图像块。
 
-`read_image` 只在持久 `ctx.attachments` 服务已挂载时注册。执行时还要求确切路由的模型声明 `image` 输入，通过 `ctx.llm.resolveModelInfo` 依次从会话最新请求 header 和 agent 选项解析。
+### 工具
 
-## 配置
+| 工具 | 参数 | 行为 |
+|---|---|---|
+| `read` | `file_path`、`offset?`、`limit?` | 带行号的 UTF-8 内容与分页 footer；`offset` 从 1 开始，`limit` 默认为配置的 `readLimit`，上限也为该值 |
+| `read_image` | `file_path` | 读取并持久保存 PNG/JPEG/WebP/GIF 源图；规范化可在下一次模型请求前缩小图片，因此模型无需先创建缩略图 |
+| `write` | `file_path`、`content` | 创建或完整替换文件；有策略插件时，覆盖要求先在未变版本上执行 `read`，创建不需要 |
+| `edit` | `file_path`、`old_string`、`new_string`、`replace_all?` | 字面量替换，除非 `replace_all` 为 true 否则要求唯一匹配；有策略插件时，要求先执行 `read` 且文件未变 |
+
+字段名使用 snake_case，与 Claude Code 和现有 harness 工具 schema 一致。成功返回紧凑信封——读取窗口、图像引用或 `Created file`/`Updated file` 确认——`write`/`edit` 还会派生可回放的 diff 卡片元数据供 UI 展示。
+
+### 配置
 
 所有键均为可选；默认值是随产品交付的读取上限。
 
 | 键 | 默认值 | 含义 |
 |---|---|---|
-| `readLimit` | `2000` | 一次 `read` 调用返回的默认和最大行数（工具 schema 将其声明为 `limit` 默认值）。 |
-| `readMaxLineLength` | `2000` | 每行截断前保留的字符数（后缀会说明上限）。 |
-| `readMaxBytes` | `51200` | 一次 `read` 调用所选行的字节上限；溢出时以「已达上限」footer 结束窗口。 |
-| `readStreamMinSize` | `10485760` | 大于等于该大小或大小未知的文件采用流式读取，而不是整体加载到内存。 |
+| `readLimit` | `2000` | 一次 `read` 调用返回的默认和最大行数 |

-## 工具（schema 见[文件系统工具 schema Agent Note](../../../.agents/notes/implemented/feature/2026-06-17-filesystem-tool-schemas.zh.md)）
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-tool-fs)是每个受支持字段及其 JSDoc 的穷尽式真源。
 
-| 工具 | 参数 | 行为 |
-|---|---|---|
-| `read` | `file_path`、`offset?`、`limit?` | 带行号的 UTF-8 内容和分页 footer。`offset` 从 1 开始；`limit` 默认为配置的 `readLimit`（2000），上限也为该值。 |
-| `read_image` | `file_path` | 通过有界字节 seam 读取 PNG/JPEG/WebP/GIF 文件，经 `ctx.attachments.saveImage` 持久保存，并在小型元数据信封旁返回图像块。Harness 会在下一次模型请求前校验并缩小受支持的大图，因此模型可以直接读取源文件，无需先创建缩略图。只有确切路由的模型声明图像输入时才会成功。 |
-| `write` | `file_path`、`content` | 创建文件或完整替换文件。有策略插件时：覆盖现有文件要求先在未变版本上执行 `read`；创建新文件不需要。没有插件时：无条件执行。 |
-| `edit` | `file_path`、非空 `old_string`、`new_string`、`replace_all?` | 字面量替换；除非 `replace_all` 为 true，否则要求唯一匹配。有策略插件时：要求先执行 `read`（任何窗口），且文件此后未变。没有插件时：无条件执行。 |
+### 策略与沙箱行为
 
-字段名使用 snake_case，与 Claude Code 和现有 harness 工具 schema 一致。
+挂载策略插件后，`write` 与 `edit` 从 `fs/*` 意图槽位取得防护，因此未读目标或陈旧观察会以 `FS_NOT_OBSERVED` 或 `FS_STALE_VERSION` 及恢复指令失败。使用施加沙箱限制的后端（`fs-sandbox`）时，`write`/`edit` 还会公开 `sandbox_permissions` 与 `justification`；被拒绝的变更返回 `[sandbox: file access denied under <mode> mode]` 标记与同轮次升级提示，获批的重试可以在该次调用中加盖严格更宽的模式。
 
-结构化成功值分别为：`read` → `{ path, offset, lines: [{ number, text }], totalLines }`，`read_image` → `{ path, image: { attachmentId, mediaType, bytes, width, height, name?, originalDimensions?: { width, height } } }`，`write` → `{ path, operation: 'create' | 'update', before: string | null, after }`，`edit` → `{ path, before, after }`。`originalDimensions` 只在规范化过程缩小提交光栅时出现，并记录应用方向后的输入尺寸。原生渲染器会保留下方带行号的读取结果和变更确认。`write` 和 `edit` 从这些值派生可回放的 diff 卡片元数据，`read` 派生可回放的读取卡片窗口 `{ path, offset, lines, totalLines, lang? }`；仅用于执行的结构化值不会添加到 `tool/result`，图片渲染器则会发出由结果记录的持久图片块。
+### 失败与恢复
 
-## 工具就是执行器；策略是事件门禁
+失败被规范化为 `Error: <message>`，并为调用方保留结构化错误码。稳定消息包括 `file_path must be a non-empty string`、`limit must be less than or equal to <max>`、`cannot read "<path>": not found`、`cannot read "<path>": not a regular file`，以及图像路由拒绝 `cannot read "<path>" as an image: model "<model>" does not declare image input; switch to an image-capable model to read images`。防护变更失败会追加恢复指令：`FS_STALE_VERSION` 追加 `— re-read the file, then retry`，`FS_NOT_OBSERVED` 追加 `— read the file, then retry`。该次重新读取确认缺失后，`edit` 报告 `FS_NOT_FOUND` 而不会重复陈旧恢复指令，`write` 则使用防护创建。
 
-工具**不**注入策略服务，也不检查任何缓存。每个工具通过 `ctx.fs.resolve(path, { cwd, signal })` 解析路径；它会传入调用 agent（智能体）的会话 cwd（`exec.agent.session.header.cwd`），使相对路径以会话工作区为基准解析并与 `dsh-tool-bash` 一致，同时把工具取消转发到解析过程（见[每会话 cwd Agent Note](../../../.agents/notes/implemented/architecture/2026-07-02-fs-per-session-cwd.zh.md)）。随后执行：
+-----
 
-- **read**：一次 `ctx.fs.stat`（用于类型、大小路由和版本），随后调用 `readText`/`streamText`，构建行窗口，再发出 `fs/observed`，使用普通 `ctx.emit`。（1 次 stat。）
-- **read_image**：在任何 I/O 之前校验参数、扩展名、附件可用性、部署接受的媒体类型和图像路由；随后一次 `ctx.fs.stat`（目标缺失时与 `read` 一样记录 `absent` 观察）、以 `imageLimits.maxImageBytes` 与 `imageLimits.maxMessageImageBytes` 中较小者为上限的有界 `ctx.fs.readBytes`（结果是携带一张图像的一条消息）、`attachments.saveImage`（内容寻址，因此在 `tool/result` 事件追加时图像块引用的对象已持久提交），最后发出 `fs/observed`。（1 次 stat。）
-- **write**：调用 `ctx.waterfall('fs/write-intent', target, exec, () => undefined)` 取得可选防护，然后调用 `ctx.fs.writeText(target, content, intent)`，再发出 `fs/observed`。（0 次 stat。）
-- **edit**：调用 `ctx.waterfall('fs/edit-intent', target, exec, () => undefined)` 取得可选防护，然后调用 `ctx.fs.editText(target, edit, intent)`，再发出 `fs/observed`。（0 次 stat。）
+<a id="understand-the-implementation"></a>
+## 理解实现
 
-工具在每次分派中把 `exec`（工具执行上下文）作为不透明 `actor` 传入。默认 thunk 返回 `undefined`（不受约束的裸提供方）。加载 `@deepseek-ai/dsh-fs-observation-policy` 后，它会占用单个决策槽：返回 `createIfAbsent`/`replaceIfVersion`/`{ version }` 或抛出 `FS_NOT_OBSERVED`，并在 `fs/observed` 时记录。后端错误（`FsError`）和抛出的 `FS_NOT_OBSERVED` 会流经 `ToolRuntime.execute()`，变成 `isError` 工具结果，并附带 `{ name, code }`。
+<details>
+<summary>实现细节——点击展开</summary>
 
-当 `ctx.fs.sandboxMode` 表明提供方施加沙箱限制时，write/edit 会公开 `sandbox_permissions` 与 `justification`，并通过 `ctx.approval` 处理获批后的重试。策略归属方会贡献与具体能力无关的常驻策略；工具结果仍保留针对具体操作的拒绝与重试引导。
+本节解释工具套件背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
 
-## `fs/observed` 发后即忘
+### 设计理念
 
-`fs/observed` 在 read/read_image/write/edit 已经成功之后，通过普通 `ctx.emit` 发出。监听器的约定是同步且只有副作用的记录器（`@deepseek-ai/dsh-fs-observation-policy` 使用 `WeakMap.set`）；工具不保护这次发出，因此监听器抛出会作为工具的 `isError` 结果出现。异步或可能失败的观察不属于该事件。
+工具就是执行器；策略是事件门禁。工具不注入策略服务，也不检查任何缓存——每次变更都通过 `ctx.waterfall` 向单一意图槽位请求防护，每个操作只在成功后发出 `fs/observed`。读取恰好执行一次提供方 `stat`（类型与大小路由加观察到的版本）；变更一次也不执行，因为防护来自意图槽位，提供方在锁内重新检查。
 
-`read` 允许并发调度，因为它唯一会改变状态的操作是同步记录版本。稍后的 `write` 或 `edit` 会在目标锁内重新检查版本，因此即使记录器发生竞态，系统也会安全地拒绝操作；两个变更工具仍保持互斥。见[并行工具调用 Agent Note](../../../.agents/notes/implemented/feature/2026-07-10-parallel-tool-call-execution.zh.md)。
+### 源码地图
 
-包根目录只导出 Cordis 插件约定（`name`、`inject`、`Config` 和 `apply`）。读取渲染（行窗口与输出格式化）位于 `src/read-render.ts`（不依赖 Cordis，单独进行单元测试）；`src/read.ts`/`read-image.ts`/`write.ts`/`edit.ts` 是工具执行器，`src/index.ts` 负责组合。

+四个工具共享同一种流程形态：用调用会话的 cwd 解析路径、运行适用的门禁、恰好执行一次提供方操作，并且只在成功后发出 `fs/observed`。`read` 与 `read_image` 为类型与大小路由付出一次 `stat`；`write` 与 `edit` 不执行 stat，因为防护来自意图槽位，提供方失败以类型化 `FsError` 结果呈现。各工具执行器位于 `src/read.ts`、`src/read-image.ts`、`src/write.ts` 与 `src/edit.ts`。
+
+### 观察与并发
+
+`fs/observed` 在操作成功之后通过普通 `ctx.emit` 发出；监听器的约定是同步且只有副作用的记录器，因此异步或可能失败的观察不属于该事件。`read` 允许并发调度，因为它唯一改变状态的操作是同步记录版本；稍后的 `write` 或 `edit` 会在目标锁内重新检查版本，因此记录器竞态会安全地失败，两个变更工具仍保持互斥。

-Standalone model-facing `str_replace_editor` over `ctx.fs`. It can be composed with persistent Bash, one-shot Bash, sandboxed Bash, or another terminal surface.
+## Summary
 
-## Config
+`dsh-tool-str-replace-editor` provides a standalone model-facing `str_replace_editor` tool over `ctx.fs`: `view` shows numbered file content or a shallow directory listing, `create` makes a new file, `str_replace` applies a unique literal replacement, and `insert` adds lines at a chosen boundary. It is composable with persistent Bash, one-shot Bash, sandboxed Bash, or another terminal surface. Mutations obey the same read-before-edit policy and sandbox fence as the rest of the fs family, enforced by whichever backend and policy plugins are mounted. Choose it when a deployment wants the Claude-Code-style single editor tool with absolute paths; the `dsh-tool-fs` package provides the alternative `read`/`write`/`edit` suite.

+## Use this package

+Mount the tool alongside a `ctx.fs` backend (and, for guarded mutations, the policy plugin) when the model should edit files through the familiar `view`/`create`/`str_replace`/`insert` command vocabulary on absolute paths.

-## Tool
+### The commands
 
-The schema provides `view`, `create`, `str_replace`, and `insert` over absolute paths. File views use one-based line numbers and preserve content tabs, so displayed text remains valid literal replacement input; directory views omit hidden, dependency, and Python-cache entries and descend two levels. A metadata miss from `view`, `str_replace`, or `insert` records confirmed absence before returning `FS_NOT_FOUND`, so a later `create` can recover an externally deleted path through the mounted policy's guarded-create flow; absence never authorizes `str_replace` or `insert`. Replacement requires one unique literal match and reports errors only in the public `old_str` vocabulary. Command-specific fields accept `null` placeholders: execution treats them as omitted when the selected command does not use them, required fields remain required, `view_range: null` selects the full view, and `str_replace.new_str: null` is rejected so deletion requires omission. Insert follows its selected zero-based boundary without adding an implicit trailing newline. Mutations preserve tabs outside the requested edit.
+`view` returns one-based numbered file content (tabs preserved, so displayed text stays valid literal replacement input) or a two-level directory listing that omits hidden, dependency, and Python-cache entries. `create` makes a new file and refuses to overwrite an existing one. Command-specific fields may contain `null` placeholders when the selected command does not use them; required fields stay required, `view_range: null` selects the full view, and `str_replace.new_str: null` is rejected so deletion requires omission. `str_replace` requires one unique literal match, with errors reported in the public `old_str` vocabulary; `insert` follows the selected zero-based insertion boundary without adding an implicit trailing newline. Mutations preserve tabs outside the requested edit.
 
+### Failures and recovery
+
+A metadata miss from `view`, `str_replace`, or `insert` records confirmed absence before returning `FS_NOT_FOUND`, so a later `create` can recover an externally deleted path through the mounted policy's guarded-create flow; absence never authorizes `str_replace` or `insert`. Guarded mutations inherit the policy plugin's codes and remedies — `FS_NOT_OBSERVED` (read the file, then retry), `FS_STALE_VERSION` (re-read, then retry) — and sandbox denials surface as the `[sandbox: file access denied under <mode> mode]` marker. Paths must be absolute; a relative path is refused with a hint.

+<details>

+
+This section explains the design decisions behind the editor tool and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The tool is one schema with four commands over `ctx.fs`. Mutations never touch the provider directly with their own assumptions: each one runs the `fs/write-intent` or `fs/edit-intent` waterfall to obtain the policy plugin's guard, resolves the per-call sandbox policy when the mounted `ctx.fs` confines, and delegates enforcement to the provider. `str_replace` and `insert` additionally re-read the file and use the observed version as the compare-and-swap basis when no policy plugin supplies a guard.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | The whole tool: schema, command dispatch, view rendering, mutation policy |
+
+### How each command runs
+
+Every command resolves the absolute path first; mutations then follow one shared flow — policy guard, provider enforcement, then an `fs/observed` record on success — while `view` only stats and renders. The entire tool — schema, command dispatch, and view rendering — lives in `src/index.ts`.

+
+### 设计理念
+
+该工具是基于 `ctx.fs` 的单一 schema、四个命令。修改操作绝不带着自己的假设直接触碰提供方：每个操作都运行 `fs/write-intent` 或 `fs/edit-intent` waterfall 以取得策略插件的防护，在已挂载的 `ctx.fs` 实施沙箱限制时解析按调用沙箱策略，并把强制执行委托给提供方。`str_replace` 与 `insert` 还会重新读取文件，并在没有策略插件提供防护时把观察到的版本作为比较并交换的基础。

+| [`src/index.ts`](src/index.ts) | 整个工具：schema、命令分派、查看渲染、修改策略 |
+
+### 各命令如何运行
+
+每个命令都先解析绝对路径；修改操作随后遵循同一条共享流程——策略防护、提供方强制执行、成功后记录 `fs/observed`——而 `view` 只执行 stat 并渲染。整个工具——schema、命令分派与查看渲染——都位于 `src/index.ts`。

-Durable objective state for an agent session, owned independently of the model-facing tools and continuation policy that consume it. Goal state is part of the owning session log; consumers depend on `dsh-goal`, never on the concrete agent loop.
+## Summary
+
+The goal group gives an agent session one durable completion objective that survives restarts, resume, and fork: the goal service keeps the goal state and lifecycle durable, the model tools let the agent create and update goals, the `/goal` command gives the human direct goal control without a model turn, and the continuation driver turns an active goal into sequential rounds of automatic work. Goal state lives in the session log, so nothing in the group keeps a separate store. Only one goal is current at a time, and a goal is state, not a scheduler — automatic continuation is an opt-in consumer you mount deliberately.

-agent 会话的持久目标状态，独立于消费它的面向模型工具与续行策略。goal 状态是所属会话日志的一部分；消费方依赖 `dsh-goal`，绝不依赖具体的 agent loop（智能体循环）。
+## 概述
+
+goal 组为 agent 会话提供一个持久的完成目标，在重启、resume（恢复）与 fork 后依然存在：goal 服务持久保存状态与生命周期，模型工具让 agent 创建和更新 goal，`/goal` 命令让用户无需模型轮次即可直接控制 goal，续行驱动器则把 active 的 goal 变成连续多轮的自动工作。goal 状态保存在会话日志中，组内没有任何独立存储。同一时刻只有一个当前 goal；goal 是状态而非调度器——自动续行是需要你刻意挂载的可选消费方。

-Human-facing `/goal` control over [`ctx.goals`](../goal/README.md). The plugin registers one command through [`ctx.commands`](../../interaction/commands/README.md) in the Cordis scope where it is mounted, so command adapters reading that scope discover and execute it without a model turn. The [human goal-command Agent Note](../../../.agents/notes/implemented/feature/2026-07-19-human-goal-command.md) owns the UX and composition decisions.
+## Summary
 
-## Command contract
+`dsh-command-goal` gives the human `/goal` command over the persisted goal service: a user can create, edit, pause, resume, clear, and inspect the current goal directly from the UI, without involving the model. The command registers in its Cordis scope, so command adapters reading that scope discover and execute it, while command text and output stay in the UI — they never enter model requests. Every accepted mutation persists through the goal service's durable `goal/change` event. Image attachments may accompany a create or edit and are submitted as one ordinary user message so later goal rounds see them. Choose it for interactive deployments with a command adapter; headless and automation apps without one do not need it.

+## Use this package
+
+Use `dsh-command-goal` in interactive deployments that mount a command adapter — the shipped Web client is the reference. It gives users direct control over the goal lifecycle without a model turn: commands execute in the UI command plane and the adapter renders their results directly.
+
+### Command reference
+
+Every sub-command runs against the current goal of the invoking agent; a bare `/goal` shows usage when no goal exists.
 
 | Input | Result |
 |---|---|
-| `/goal` | Show the current objective, durable phase, round count/cap, process-local activation, and valid next commands; a blocked goal also shows its policy code and explanation, while no goal shows usage. |
-| `/goal <objective>` | Create and arm a goal, or replace a completed goal with a fresh identity. An unfinished goal is never replaced without an explicit clear. |
-| `/goal edit <objective>` | Edit the current objective without changing its phase or activation. Editing a completed goal creates a fresh active goal. |
-| `/goal pause` | Pause an active goal and disarm continuation. |
-| `/goal resume` | Resume a stopped goal or rearm an active goal after session resume/fork, subject to its remaining round cap. |
-| `/goal clear` | Clear the current pointer while retaining its durable history and tombstone. |

-Control words are case-insensitive only when they occupy the complete input. Every other non-empty suffix is an objective, so `/goal pause after verification` creates that literal objective. The goal domain trims and validates objectives. Because the generic command plane has no modal editor or confirmation primitive, `edit` takes its replacement inline and an unfinished replacement returns a direct error instructing the user to edit or clear.
+### Input grammar
 
-The command declares `input.images`, so composer image attachments may accompany an invocation. Attachments only accompany an objective: on a successful create or edit the producer submits one user followup carrying the admitted image blocks plus the fixed text `Reference images for the goal objective.`, so later goal rounds read them from ordinary session history without the goal domain storing attachment state. Every other sub-command, and any refused create or edit, returns a direct error and submits nothing, so the dispatching composer keeps the images.

+
+### Design
+
+- **Grammar, not free text.** The parser recognizes only the exact control words (`clear`, `pause`, `resume`, `edit`) when they fill the whole input; every other non-empty suffix is an objective. `edit` alone is invalid, and `edit` refuses to replace an unfinished goal directly.
+- **Domain rejections become stable errors.** `GoalError` outcomes are converted into direct command errors with a fixed message; unexpected failures rethrow so adapters report a command failure rather than a domain result. Rendered output never exposes branded ids or revisions.
+- **Attachments ride the objective.** On a successful create or edit the command submits one user followup carrying the admitted image blocks plus the fixed text `Reference images for the goal objective.`; every other path submits nothing, so the dispatching composer keeps the images.

-面向用户的 `/goal` 控制，基于 [`ctx.goals`](../goal/README.zh.md) 实现。该插件通过 [`ctx.commands`](../../interaction/commands/README.zh.md) 在自身挂载的 Cordis scope 中注册一个命令，因此读取该 scope 的命令适配器都能发现并执行它，无需模型轮次。[用户 goal 命令 Agent Note](../../../.agents/notes/implemented/feature/2026-07-19-human-goal-command.zh.md) 负责用户体验与组合决策。

-Same-session continuation driver for [`ctx.goals`](../goal/README.md). It turns an active, armed goal into sequential [goal rounds](../../../docs/glossary.md#goal-round) through the public `Agent` and session services; the [same-session driver Agent Note](../../../.agents/notes/implemented/feature/2026-07-19-same-session-goal-round-driver.md) owns the race and lifecycle rationale.
+## Summary
 
-## Composition
+`dsh-goal-round-driver` automatically continues an active goal in the same session: whenever the agent is idle with an active, armed goal and remaining round capacity, the driver starts the next goal round. Each round is one model turn toward the objective, driven by a retained goal-round prompt; only goal-sourced rounds count against the goal's round cap, and the goal records a blocker when the cap is exhausted. The driver has no configuration of its own — the round cap belongs to the goal definition and the model-facing blocked threshold belongs to `dsh-tool-goal`, so policy stays in one place. Mount it together with `dsh-goal` and `dsh-tool-goal` when a task should work itself toward completion across rounds; leave it out when every step needs human steering.

-## Round contract
+### What each round does
 
-When an exact live agent is idle with an active, armed goal and remaining capacity, the driver first checkpoints pending goal mutations, then reserves `roundsStarted + 1` for the current `{ goalId, revision }`. It queues one `<goal_round>` prompt with `GoalMessageSource`. The `agent/pre-step` listener verifies the complete claimed record and current goal both before and after downstream listeners; an accepted round sets `startsRequestSeries: true`, so that boundary is logged as `series` for an unchanged header or `startsSeries: true` on a coincident `change`. Chat renders the header before the round message to match the provider envelope order. Only an entered `user/message` increments `roundsStarted`. A reservation rejected as stale does not consume the round number.
+With an exact live agent idle, an active armed goal, and remaining capacity, the driver queues one goal-round prompt. It names the JSON-quoted objective, round number, and cap, and tells the model to use current workspace, tool results, and durable state as authority. An accepted round starts a distinct request series, so Chat renders its self-contained request header before the goal message. The round enters history as a goal-sourced user message; only an entered goal message consumes the cap, while human messages and stale reservations do not. Goal lifecycle mutations still require the independent authority checks in `dsh-tool-goal`.
 
-`MessageId` identifies the reserved message through durable inbox insertion and claim; it does not identify a turn result. Human messages do not consume the goal cap. If human work enters the inbox before a reservation or joins its pending batch, automatic work yields until the agent becomes idle; a pending automatic prompt in a mixed batch is rejected and re-reserved only after that checkpoint.
+### When continuation stops
 
-The retained prompt names the JSON-quoted objective and `round/maxGoalRounds`, treats the current workspace, tool results, and durable session state as authoritative, requires evidence before completion, and tells the model to leave the goal active when work remains. Quoting preserves multiline or tag-like objective text as data. Goal lifecycle mutations still require the independent authority checks in `dsh-tool-goal`.
+A round starts only at whole-agent idle, and completion, pause, and blocking suppress continuation; an edit only invalidates an in-flight round through the revision fence, and the driver continues the new revision. The driver also stops on its own when a turn ends on max tokens, a durability write fails, the agent is cancelled, the plugin unloads, or the round cap is exhausted — at the cap it records a blocker with the stable code `round-limit`. Cancellation never auto-restarts a round: a goal whose round was under way or already queued is paused at the next idle point, and a cancellation unrelated to a goal attempt only disarms continuation.
 
-## Idle checkpoint
+### After resume, fork, or unload
 
-At whole-agent idle, durable goal phase and revision are authoritative. An active, armed goal with capacity reserves its next round; completion, pause, blocking, and edits suppress continuation. The driver does not classify the preceding activity by correlating the goal message with `turn/end`, so provider errors and token limits are not prompt-level goal outcomes.
+Mounting the driver over an existing agent never arms a goal, and after session resume or fork an active goal stays disarmed until an explicit human-authorized resume — the driver never revives work on its own. Unloading the plugin cancels any in-flight round and ensures no later round starts.
 
-## Lifecycle and durability
+-----
 
-`goal/changed` creates a durability obligation. Before queuing work, the driver awaits `ctx.sessions.flush()` and rechecks both the goal revision and competing input after the await. A flush failure arriving through `agent/error` disarms continuation before another round can start.
+<a id="understand-the-implementation"></a>
+## Understand the implementation
 
-Activation is never inherited when this plugin loads over an existing agent. `GoalService.disarm()` removes process-local authority without changing durable phase, revision, or history; explicit human-authorized resume records the later reactivation. The same rule applies after session resume and fork through the goal domain's `agent/session-start` handling.
+<details>
+<summary>Implementation internals — click to expand</summary>
 
-Cancellation removes pending inbox work or leaves an agent-wide aborted state. At the next idle checkpoint the driver pauses a goal with a reserved or admitted attempt so cancellation cannot auto-restart it; cancellation unrelated to a goal attempt only disarms process-local continuation. If the pause mutation fails, the driver falls back to disarming. Plugin teardown closes admission, disarms every live goal, cancels active work with the `parent` cause, and awaits the driver plus agent quiescence while its event fence remains installed.
+This section explains how the driver schedules rounds without races; the observable behavior is covered in [Use this package](#use-this-package).
 
+### Design
+
+- **Reservation, then admission.** At idle the driver reserves `roundsStarted + 1` for the current `{ goalId, revision }`, queues one `<goal_round>` prompt with a goal message source, and only an entered `user/message` increments `roundsStarted`. A reservation rejected as stale does not consume the round number.
+- **Race fences.** The `agent/pre-step` listener verifies the complete claimed record against the current goal both before and after downstream listeners, so a stale, cancelled, or competing prompt is rejected before its step enters. Human work that arrives before a reservation makes automatic work yield until the agent is idle again.
+- **Durability checkpoint.** `goal/changed` creates a durability obligation: before queuing work the driver awaits `ctx.sessions.flush()` and rechecks the goal revision and competing input after the await. A flush failure arriving through `agent/error` disarms continuation before another round can start.
+- **Fail-closed teardown.** Teardown closes admission, disarms every live goal, cancels active work with the `parent` cause, and awaits the driver plus agent quiescence while its event fence remains installed.

 - **No independent evaluator** — the model-facing goal policy decides when evidence is sufficient for completion and whether a blocker is semantically unchanged; evaluator-backed certification remains deferred.
 - **Same-session execution only** — this package deliberately does not spawn a fresh agent, fork a session prefix, or implement Ralph-style independent attempts; that workflow belongs to its own plugin layer.
 - **Accepted-queue unload race** — Cordis plugin unload is asynchronous. A goal prompt already accepted by the agent inbox can begin and consume its round before unload starts; teardown then cancels the request, disarms the goal, and awaits quiescence. No later round starts.
 - **Round cap, not resource budget** — token, currency, time, and provider quota policies remain independent. Their session events are not attributed to the goal message or mapped into goal blocker codes.
 - **No abnormal auto-retry** — transient provider and persistence failures require a later human-authorized resume rather than an implicit retry policy.

+## 概述
 
-## 组合
+`dsh-goal-round-driver` 会在同一会话中自动继续 active 的 goal：每当 agent 空闲且存在 active、已启用续行并有剩余容量的 goal 时，驱动器就会启动下一个 Goal Round。每一轮都是朝目标前进的一次模型轮次，由保留的 goal-round 提示词驱动；只有来源为 goal 的 Round 会计入 goal 的 Round 上限，上限耗尽时 goal 会记录一个 blocker。驱动器没有自己的配置——Round 上限属于 goal 定义，面向模型的阻塞阈值属于 `dsh-tool-goal`，策略因此只保留在一处。当任务应跨多轮自行推进时，与 `dsh-goal` 和 `dsh-tool-goal` 一起挂载它；当每一步都需要人工 steering（中途引导）时，不要挂载。

-## Round 约定
+### 每轮做什么
 
-当对应的活跃 agent（智能体）实例处于 idle 状态，且目标 phase 为 active、已启用续行并有剩余容量时，驱动器先为待处理 goal 变更创建检查点，再预留 `roundsStarted + 1`，对应当前 `{ goalId, revision }`。它会排入一条 `<goal_round>` 提示词，并携带 `GoalMessageSource`。`agent/pre-step` 监听器会在下游监听器前后验证完整的已领取记录与当前 goal；接纳的 Round 会设置 `startsRequestSeries: true`，因此未变化的 header 以 `series` 记录该边界，而同时发生的 `change` 则携带 `startsSeries: true`。Chat 会把该 header 渲染在 Round 消息之前，以匹配提供方信封顺序。只有进入步骤的 `user/message` 才会增加 `roundsStarted`。因陈旧而被拒绝的预留不会消耗 Round 编号。
+当对应的活跃 agent 处于 idle，且存在 active、已启用续行、仍有容量的 goal 时，驱动器会排入一条 goal-round 提示词。它点明以 JSON 引用的目标、Round 编号与上限，并告诉模型以当前工作区、工具结果和持久状态为准。被接纳的 Round 会开启独立请求序列，因此 Chat 会在 goal 消息之前渲染其自包含请求 header。该 Round 以 goal 来源的用户消息进入历史；只有进入步骤的 goal 消息消耗上限，人类消息和陈旧预留不会消耗。goal 生命周期变更仍必须通过 `dsh-tool-goal` 的独立权限检查。
 
-`MessageId` 通过持久 inbox 插入和领取来标识预留消息；它不标识轮次结果。人类消息不消耗 goal 上限。如果人类工作在预留前进入 inbox，或加入预留的待处理批次，自动工作会让行，直到 agent 进入 idle；混合批次中的待处理自动提示词会被拒绝，只有在该检查点之后才重新预留。
+### 何时停止续行
 
-保留的提示词会点明经过 JSON 引用的目标与 `round/maxGoalRounds`，将当前工作区、工具结果和持久会话状态视为权威信息，要求在完成前提供证据，并要求在工作仍未完成时保持目标 active。引用可将多行或形似标签的目标文本保留为数据。goal 生命周期变更仍必须通过 `dsh-tool-goal` 的独立权限检查。
+Round 只在整个 agent 进入 idle 时启动；完成、暂停和阻塞会阻止续行；编辑只会通过修订栅栏使进行中的 Round 失效，驱动器会继续新修订。驱动器也会在以下情况自行停止：轮次因 max tokens 结束、持久性写入失败、agent 被取消、插件卸载，或 Round 上限耗尽——上限耗尽时它会以稳定代码 `round-limit` 记录一个 blocker。取消绝不会自动重启 Round：Round 已在进行或已排入队列的 goal 会在下一次 idle 时被暂停；与 goal 尝试无关的取消只会停用续行。
 
-## Idle 检查点
+### resume、fork 或卸载之后
 
-整个 agent 进入 idle 时，持久 goal phase 和 revision 具有权威性。phase 为 active、已启用续行且仍有容量的 goal 会预留下一 Round；完成、暂停、阻塞和编辑都会阻止续行。驱动器不会通过关联 goal 消息与 `turn/end` 来对前一段活动分类，因此提供方错误和 token 上限不属于提示词级 goal 结果。
+把驱动器挂载到现有 agent 上绝不会启用任何 goal 的续行；会话 resume 或 fork 后，active 的 goal 会保持停用续行，直到用户明确授权 resume——驱动器绝不会自行复活工作。卸载插件会取消进行中的 Round，并确保不再启动后续 Round。
 
-## 生命周期与持久性
+-----
 
-`goal/changed` 会产生持久性义务。排队工作前，驱动器会等待 `ctx.sessions.flush()`，并在等待后重新检查 goal revision 与竞争输入。通过 `agent/error` 到达的 flush 失败会停用续行，避免另一 Round 启动。

+## 理解实现
 
-此插件加载到现有 agent 上时绝不会继承续行启用状态。`GoalService.disarm()` 会移除进程本地权限，而不改变持久 phase、revision 或历史；之后由用户明确授权的 resume 会记录重新启用续行。会话 resume 和 fork 后，goal 领域通过 `agent/session-start` 处理应用相同规则。

-取消会移除 inbox 中待处理的工作，或留下 agent 范围的 aborted 状态。在下一次 idle 检查点，驱动器会暂停存在已预留或已准入尝试的 goal，避免取消后自动重启；与 goal 尝试无关的取消只会撤销进程本地续行权限。如果 pause 变更失败，驱动器会回退到停用续行。插件 teardown 会关闭准入，停用所有活跃 goal 的续行，以 `parent` cause 取消正在进行的工作，并在事件防护仍生效的情况下等待驱动器和 agent 完全停稳。

+### 设计
+
+- **先预留，后准入。** idle 时驱动器为当前 `{ goalId, revision }` 预留 `roundsStarted + 1`，排入一条携带 goal 消息来源的 `<goal_round>` 提示词；只有进入步骤的 `user/message` 才会增加 `roundsStarted`。因陈旧而被拒绝的预留不会消耗 Round 编号。
+- **竞态防护。** `agent/pre-step` 监听器会在下游监听器前后验证完整的已领取记录与当前 goal，因此陈旧、已取消或竞争中的提示词会在其步骤进入前被拒绝。在预留前到达的人类工作会让自动工作让行，直到 agent 重新进入 idle。
+- **持久性检查点。** `goal/changed` 会产生持久性义务：排队工作前，驱动器会等待 `ctx.sessions.flush()`，并在等待后重新检查 goal revision 与竞争输入。通过 `agent/error` 到达的 flush 失败会停用续行，避免另一 Round 启动。
+- **默认关闭的 teardown。** Teardown 会关闭准入、停用所有活跃 goal 的续行、以 `parent` 原因取消进行中的工作，并在事件防护仍生效的情况下等待驱动器和 agent 完全停稳。

 English | [中文](README.zh.md)
 
-Event-sourced same-session goal state. The service retains one current completion objective in an agent's existing session while keeping permission to continue as process-local activation. The [goal-domain Agent Note](../../../.agents/notes/implemented/feature/2026-07-19-persisted-same-session-goal-domain.md) owns the design rationale; the [goal type catalog](../../../docs/subsystems/goal.md) records the literal data shapes.
+## Summary
 
-## Config
+`dsh-goal` keeps one durable completion objective per agent session: the goal's text, phase, round count, and revision history live in the session log, so they survive session resume, fork, and process restarts. You can create, edit, pause, resume, complete, block, and clear a goal, and every mutation is compare-and-set, so a stale view cannot clobber newer state. A goal carries a round cap (default 256) that bounds automatic continuation, and a blocked goal keeps a stable policy code plus a human explanation. It is state, not a scheduler: the service decides nothing about when work continues, and continuation permission is process-local and never persisted. Choose it when one long-running objective should span many turns; skip it for routine single-turn work.

+## Use this package
+
+Mount `dsh-goal` whenever a session should remember one long-running completion objective across many turns and restarts. The package is a service: the model tools, the `/goal` command, and the continuation driver are separate packages that consume the same goal state, so mounting only this package stores and serves the goal without starting any work.
+
+### When to use it
+
+A goal suits one long-running completion objective that should continue across autonomous goal rounds — for example shipping a migration or fixing every failing documentation gate. Routine single-turn work should not create a goal. The service keeps at most one current goal per session: an unfinished goal must be edited, paused, resumed, blocked, or cleared before another takes its place, while a completed goal can be replaced directly.
+
+### Set up the service
+
+Load the package with a composition entry; the only deployment choice is the default round cap applied to creates that do not name their own.
 
 ```yaml
-- id: goal
-  name: '@deepseek-ai/dsh-goal'
+- name: '@deepseek-ai/dsh-goal'
   config:
     defaultMaxGoalRounds: 256
 ```
 
-`defaultMaxGoalRounds` must be a positive safe integer. `create()` materializes this deployment default internally before committing a goal; a request-level value overrides it.
+| Field | Default | Meaning |
+|---|---|---|
+| `defaultMaxGoalRounds` | `256` | Round cap applied when a create request omits its own |
 
-## Service contract
+`defaultMaxGoalRounds` must be a positive safe integer; a create request that names its own cap overrides it. The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-goal) is the exhaustive source for every accepted field.
 
-`ctx.goals` accepts only the exact live `Agent` instance registered under its id. `get()` returns a detached `GoalView`; mutations use a `GoalRef { id, revision }` compare-and-set fence and reject stale refs. The service exposes create, edit, pause, resume, complete, block, and clear verbs through the generated region of [goal.md](../../../docs/subsystems/goal.md#cordis-surface). Creation default resolution is internal. `disarm()` is the lifecycle-only exception: it removes process-local continuation authority without writing a revision or emitting a mutation.
+### Drive the lifecycle
 
-At most one goal is current. Creation produces an active revision-one goal and arms it. A non-complete goal must be edited, transitioned, or cleared; a completed goal may be replaced by a globally fresh id. Edits retain phase, blocker reason, and activation. Pause, completion, blocking, and clear disarm activation. A block records a policy-owned lower-kebab-case code plus a normalized free-form explanation; provider limits, configured budgets, execution errors, and requests for human input all use this one durable phase rather than multiplying lifecycle states. Resume accepts a stopped phase or a disarmed active goal only while the configured round cap has remaining capacity; it clears any former blocker reason. An active armed goal rejects the redundant operation.
+A goal moves through four durable phases — `active`, `paused`, `blocked`, `complete` — plus a process-local flag that says whether automatic continuation is armed. The verbs:
 
-Every mutation appends a durable `goal/change` event carrying the complete post-mutation snapshot; clear uses a revisioned tombstone. Goal state therefore does not depend on inbox placement, claim, admission, or discard. The session log is the only durable authority.
+| Operation | What it does |
+|---|---|
+| `create` | Starts an active goal with an objective and round cap |
+| `edit` | Changes the objective and/or round cap without changing the phase |
+| `pause` | Stops automatic continuation and keeps the state |
+| `resume` | Restarts continuation; also rearms an active goal after session resume or fork |
+| `complete` | Marks the goal achieved and stops continuation |
+| `block` | Records a stable blocker code and explanation |
+| `clear` | Removes the current goal; its history stays in the session log |
 
-Strict replay derives lifecycle mutations only from `goal/change` and rejects malformed shapes, discontinuous revisions, illegal lifecycle transitions, non-monotonic per-goal timestamps, and non-sequential admitted goal rounds. Positive rounds advance only on admitted goal-sourced `user/message` events. Mutation timestamps clamp against the preceding goal update when wall time moves backward. Incremental replay retains its cursor at the first corrupt event, and `goal/changed` fires after the durable event commits with listener failures contained.
+Pause, completion, blocking, and clear all disarm continuation. Blocking is the one phase that keeps a policy-owned lower-kebab-case code and a free-form explanation, so provider limits, exhausted budgets, execution errors, and requests for human input share a single durable phase instead of multiplying lifecycle states. Resume accepts a stopped goal, or an active but disarmed one, only while the round cap has remaining capacity, and it clears any former blocker reason.
 
-Activation is never persisted. A fresh cache and every `agent/session-start` edge disarm it even when replay finds an active durable phase. A continuation driver also calls `disarm()` before unload or after durability uncertainty. Session resume, fork, and driver replacement therefore retain the objective, phase, revisions, and admitted-round count without initiating work; a later explicit resume mutation must arm continuation.
+### What survives and what does not
 
-The separately published `./invariant` companion maintains an independent fold of each attached session. It rejects malformed goal changes, discontinuous revisions, illegal lifecycle transitions, timestamp regressions, and non-sequential admitted rounds before the candidate event enters the durable log.
+Every accepted change is recorded durably in the session log — the only store of goal state — so goal state never depends on transient message delivery. After session resume or fork, the goal, its phase, its revisions, and its admitted-round count are all still there. Automatic continuation is the exception: an active goal is disarmed after any session-start edge, so the agent does not continue on its own until someone explicitly resumes it.
 
-## Extension points
+### Observing a goal
 
-Policy plugins call the service verbs and react to the scoped `goal/changed` event. A continuation consumer admits rounds as `user/message` events with `GoalMessageSource`; ordinary human turns never increment `roundsStarted`. Consumers use the `Agent` interface and events rather than importing `dsh-agent-loop`.
+Consumers read the current goal with `ctx.goals.get(agent)` and receive a detached view: objective, phase, rounds started versus the cap, blocker reason when blocked, and whether continuation is armed. Mutations must carry the exact `{ id, revision }` from that view, so a consumer holding older state receives a clear stale-revision error instead of silently overwriting newer state:
 
+```text
+const view = ctx.goals.get(agent)      // undefined when no goal is current
+view.phase                             // 'active' | 'paused' | 'blocked' | 'complete'
+view.roundsStarted, view.maxGoalRounds // continuation progress
+view.activation                        // 'armed' | 'disarmed' — not persisted
+```

+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the service realizes the behavior above; the observable contract is covered in [Use this package](#use-this-package).
+
+### Design
+
+- **Event-sourced state.** Every mutation appends a durable `goal/change` event (version 1) carrying the complete post-mutation snapshot; `clear` writes a revisioned tombstone. The session log is the only durable authority.
+- **Compare-and-set mutations.** `ctx.goals` accepts only the exact live `Agent` registered under its id. `get()` returns a detached `GoalView`; mutations take a `GoalRef { id, revision }` and reject stale refs. Creation resolves the deployment default internally before committing.
+- **Activation is process-local.** `armed` and `disarmed` live in a per-session cache and are never persisted. A fresh cache and every `agent/session-start` edge disarm continuation even when replay finds an active durable phase; `disarm()` removes authority without writing a revision or emitting a mutation.
+- **Strict replay.** The fold derives lifecycle mutations only from `goal/change` and rejects malformed shapes, discontinuous revisions, illegal phase transitions, non-monotonic per-goal timestamps, and non-sequential admitted rounds. Positive rounds advance only on admitted goal-sourced `user/message` events, and mutation timestamps clamp against the preceding update when wall time moves backward.
+- **Projection unit.** The package registers a last-wins `goal` projection (the whole current goal, or `null`) that activates only when a projection registry is composed.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `GoalService`, config schema, mutations, activation cache, projection unit |
+| [`src/domain.ts`](src/domain.ts) | Durable change payloads, `goal/changed` event, goal message-source attribution |
+| [`src/types.ts`](src/types.ts) | Pure client-safe types: `GoalView`, `GoalSnapshot`, projection-key declaration |
+| [`src/fold.ts`](src/fold.ts) | Strict replay fold and decoder for durable goal changes |
+| [`src/runtime.ts`](src/runtime.ts) | `GoalId` brand, `GoalError` codes, change-version constant |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion: independent incremental fold over every attached session |
+
+### Events and attribution
+
+`goal/changed` fires after the durable event commits, with listener failures contained; the payload carries the operation, the exact ref, and the fresh view (absent for a clear tombstone). Admitted continuation rounds are attributed through `GoalMessageSource { goalId, revision, round }` on the `user/message` event, which the strict fold validates as the next admitted round of the current goal.

-事件溯源的同会话目标状态。该服务在 agent（智能体）的现有会话中保留一个当前待完成目标，同时将继续执行的权限作为进程本地续行启用状态。[goal 领域 Agent Note](../../../.agents/notes/implemented/feature/2026-07-19-persisted-same-session-goal-domain.zh.md) 负责设计理由；[goal 类型目录](../../../docs/subsystems/goal.zh.md)记录具体的数据形状。
+## 概述
 
-## 配置
+`dsh-goal` 为每个 agent 会话保留一个持久的完成目标：目标的文本、phase、Round 数量与 revision 历史都保存在会话日志中，因此会话 resume（恢复）、fork 与进程重启后依然存在。你可以 create、edit、pause、resume、complete、block 和 clear 一个 goal，且每次变更都是比较并设置，陈旧的视图不会覆盖更新的状态。goal 带有 Round 上限（默认 256）以约束自动续行，被阻塞的 goal 会保留稳定的策略代码和面向人的说明。它是状态而非调度器：服务不决定工作何时继续，续行权限是进程本地的且绝不持久化。当单个长期目标需要横跨多轮时选择它；常规单轮工作不要使用。

+## 使用本包
+
+当会话需要在多轮与多次重启之间记住一个长期完成目标时，挂载 `dsh-goal`。本包是服务：模型工具、`/goal` 命令与续行驱动器都是消费同一 goal 状态的独立包，因此只挂载本包只会存储和提供 goal，不会启动任何工作。
+
+### 何时使用
+
+goal 适合一个需要跨自动 Goal Round 持续的长期完成目标——例如完成一次迁移，或修复所有失败的文档门禁。常规单轮工作不应创建 goal。服务每会话至多保留一个当前 goal：未完成的 goal 必须先 edit、pause、resume、block 或 clear，才能被另一个替代；已完成的 goal 可以直接被替换。
+
+### 配置服务
+
+通过组合配置项加载本包；唯一的部署选择是默认 Round 上限，应用于未自行指定上限的 create。
 
 ```yaml
-- id: goal
-  name: '@deepseek-ai/dsh-goal'
+- name: '@deepseek-ai/dsh-goal'
   config:
     defaultMaxGoalRounds: 256
 ```
 
-`defaultMaxGoalRounds` 必须是正的安全整数。`create()` 会在提交目标前于内部物化这项部署默认值；请求级取值可以覆盖它。
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `defaultMaxGoalRounds` | `256` | 当 create 请求省略上限时应用的 Round 上限 |
 
-## 服务约定
+`defaultMaxGoalRounds` 必须是正的安全整数；指定了自身上限的 create 请求会覆盖它。生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-goal)是每个受支持字段的穷尽式真源。
 
-`ctx.goals` 只接受以对应 id 注册的完全相同的活跃 `Agent` 实例。`get()` 返回与内部状态脱离的 `GoalView`；变更以 `GoalRef { id, revision }` 作为比较并设置防护，并拒绝陈旧引用。服务通过 [goal.md](../../../docs/subsystems/goal.zh.md#cordis-surface) 的生成区块公开 create、edit、pause、resume、complete、block 和 clear 动词。创建默认值在内部解析。`disarm()` 是仅供生命周期使用的例外：它移除进程本地续行权限，不写入新 revision，也不发出变更事件。
+### 驱动生命周期
 
-最多只有一个当前目标。创建操作会生成 revision 为 1、phase 为 active 的目标并启用续行。未完成的目标必须编辑、转换或清除；已完成目标可以由拥有全局未使用过的 id 的目标替换。编辑会保留 phase、blocker reason 与 activation。暂停、完成、阻塞和清除都会停用续行。阻塞会记录策略自有的 lower-kebab-case 代码和规范化的自由文本说明；提供方限制、配置预算、执行错误与请求人工输入都使用这一种持久 phase，不会扩增生命周期状态。只有配置的 Round 上限仍有剩余容量时，resume 才接受已停止 phase 或 phase 为 active 但已停用续行的目标；它会清除原 blocker reason。phase 为 active 且已启用续行的目标会拒绝冗余操作。
+goal 经历四种持久 phase——`active`、`paused`、`blocked`、`complete`——外加一个进程本地标志，表示自动续行是否已启用。动词如下：
 
-每次变更都会追加持久的 `goal/change` 事件，其中携带变更后的完整快照；clear 使用带 revision 的 tombstone。因此，goal 状态不依赖 inbox 放置、领取、准入或丢弃。会话日志是唯一的持久权威。
+| 操作 | 作用 |
+|---|---|
+| `create` | 以目标和 Round 上限启动一个 active goal |
+| `edit` | 修改目标和/或 Round 上限，不改变 phase |
+| `pause` | 停止自动续行并保留状态 |
+| `resume` | 重新开始续行；也用于会话 resume 或 fork 后重新启用 active goal |
+| `complete` | 标记 goal 已完成并停止续行 |
+| `block` | 记录稳定的 blocker 代码与说明 |
+| `clear` | 移除当前 goal；其历史保留在会话日志中 |
 
-严格回放只从 `goal/change` 派生生命周期变更，并拒绝形状错误、不连续 revision、非法生命周期转换、每目标时间戳非单调，以及不连续的已准入 Goal Round。只有来源为 goal 且已准入的 `user/message` 事件会推进正数 Round。挂钟时间倒退时，变更时间戳会限制在不早于上一次目标更新的值。增量回放会把游标保留在第一个损坏事件处；`goal/changed` 会在持久事件提交后触发，监听器失败会被隔离处理。
+pause、complete、block 和 clear 都会停用续行。block 是唯一保留策略自有 lower-kebab-case 代码与自由文本说明的 phase，因此提供方限制、预算耗尽、执行错误与请求人工输入共用一种持久 phase，而不是扩增生命周期状态。resume 只在 Round 上限仍有剩余容量时接受已停止的 goal，或 active 但已停用续行的 goal，并清除任何先前的 blocker reason。
 
-续行启用状态绝不持久化。新缓存与每次触发 `agent/session-start` 时都会停用续行，即使回放找到了持久 phase 为 active 的目标。续行驱动器在卸载前或持久性不确定后也会调用 `disarm()`。因此，会话恢复、fork 与驱动器替换会保留目标、phase、revision 和已准入 Round 数量，却不会启动工作；之后必须通过显式 resume 变更重新启用续行。
+### 什么会保留，什么不会
 
-单独发布的 `./invariant` 配套模块会为每个已挂接会话维护独立折叠。它会在候选事件进入持久日志前拒绝格式错误的 goal 变更、不连续 revision、非法生命周期转换、时间戳回退，以及不连续的已准入 Round。
+每项被接受的变更都会持久记录到会话日志——goal 状态的唯一存储——因此 goal 状态绝不依赖临时消息投递。会话 resume 或 fork 后，goal、其 phase、其 revision 与已准入 Round 数量都仍然存在。自动续行是例外：任何会话开始边界之后，`active` 的 goal 都会被停用续行——在有人显式 resume 之前，agent 不会自行继续。
 
-## 扩展点
+### 观察 goal
 
-策略插件调用服务动词，并响应限定范围的 `goal/changed` 事件。续行消费方将 Round 准入为 `user/message` 事件，并携带 `GoalMessageSource`；普通的人类轮次绝不会增加 `roundsStarted`。消费方使用 `Agent` 接口和事件，不导入 `dsh-agent-loop`。
+消费方用 `ctx.goals.get(agent)` 读取当前 goal，获得脱离内部状态的视图：目标、phase、已开始与上限 Round 数量、被阻塞时的 blocker reason，以及续行是否已启用。变更必须携带该视图中的精确 `{ id, revision }`，因此持有旧状态的消费方会收到清晰的陈旧 revision 错误，而不是静默覆盖更新的状态：
 
+```text
+const view = ctx.goals.get(agent)      // undefined when no goal is current
+view.phase                             // 'active' | 'paused' | 'blocked' | 'complete'
+view.roundsStarted, view.maxGoalRounds // continuation progress
+view.activation                        // 'armed' | 'disarmed' — not persisted

 English | [中文](README.zh.md)
 
-The model-facing control tools for [`ctx.goals`](../goal/README.md): `get_goal`, `create_goal`, and `update_goal`. The [goal-tool Agent Note](../../../.agents/notes/implemented/feature/2026-07-19-model-facing-goal-tools.md) owns the authority split and Codex-shaped UX.
+## Summary
 
-## Tools
+`dsh-tool-goal` gives the model three tools over the persisted goal service: `get_goal` reads the current goal, `create_goal` starts a new one, and `update_goal` edits, pauses, resumes, completes, or blocks it. The model may infer a long-running objective from a direct human request and create a goal; updates must carry the exact id and revision read beforehand. Authority is enforced at execution: create, edit, pause, and resume require a direct human turn on a top-level agent, while complete and blocked also accept the current goal round during automatic continuation. A configured threshold (default 3) bounds how soon an autonomous round may self-report `blocked`. Mount it with `dsh-goal` whenever the model should manage goals itself.
 
-- `get_goal()` returns the current goal or `null`, including the compare-and-set id/revision, durable phase, admitted/capped goal rounds, any blocker reason, and current process-local activation.
-- `create_goal(objective, max_goal_rounds?)` creates one goal from a direct top-level human turn. The model may infer long-running goal intent without an exact command phrase; non-human turns and subagents are rejected at execution.
-- `update_goal(goal_id, revision, action, objective?, max_goal_rounds?, blocked_reason?)` supports `edit`, `pause`, `resume`, `complete`, and `blocked`. Replacements belong only to `edit`; `blocked_reason` is required only for `blocked` and is persisted with the stable code `model-reported`. Strict-schema empty-string and zero fillers count as omitted, while meaningful values remain limited to their action.
+## Table of Contents
 
-All calls are exclusive, so a model-ordered batch observes earlier mutations and their new revisions. UI clients receive pure generic cards: read for `get_goal`, other for mutations. Mutation cards select the first meaningful action value and otherwise show the goal id, so accepted fillers never produce blank input.

-All three canonical values match the compact JSON already rendered to Native callers: `{ goal: null }` or `{ goal: { id, revision, objective, phase, roundsStarted, maxGoalRounds, blockedReason? }, activation }`. Programmatic consumers therefore receive the same domain structure without parsing the rendered JSON.
+-----
 
-An autonomous goal round that successfully reports `complete` or `blocked` marks that tool execution with `concludeTurn()` so the physical turn stops after the step. Direct-human mutations never contribute this stop: the assistant may acknowledge the change and concurrent human steering remains available to the loop.
+<a id="use-this-package"></a>
+## Use this package
 
-## Authority
+Mount `dsh-tool-goal` beside the goal service when the model should create and update persisted goals itself. The tools are the model-facing half of the goal surface; the `/goal` command is the human-facing half, and the continuation driver uses the same tools to complete or block goals at the end of autonomous rounds.
 
-Execution requires the exact live `exec.agent`, its inherited `AgentRegistry` initiator, running status, and an open turn. Create, edit, pause, and resume additionally require an accepted `{ kind: 'user' }` message or steering event in a runtime-root agent's current turn. Durable fork lineage does not demote a resumed root; live subagent ownership does.
+### Tools
 
-`{ kind: 'user' }` is a host attestation. `Agent.followup()` and `steer()` assign it when their caller omits a source, so plugins, schedulers, and other non-human producers must pass their own source rather than inheriting human authority.
+All three tools return the same compact JSON — `{ goal: null }` when no goal is current, otherwise the goal's id, revision, objective, phase, rounds started, round cap, optional blocker reason, and whether continuation is armed — matching what Native callers already render.
 
-Complete and blocked also accept the exact current goal round: a goal-sourced `user/message` whose id, revision, and round equal the folded current goal. A goal-round blocked call is mechanically rejected until `blockedAfterConsecutiveRounds`; the model judges whether the same condition actually persisted and must describe it in `blocked_reason`. Direct human authority may stop a goal immediately.
+| Tool | What it does |
+|---|---|
+| `get_goal()` | Reads the current goal, or `null` when none is current |

+| `update_goal(goal_id, revision, action, objective?, max_goal_rounds?, blocked_reason?)` | `edit`, `pause`, `resume`, `complete`, or `blocked` on the exact goal revision |
 
-## Config

+### Authority rules
+
+The tools execute only for the exact live calling agent inside its active driver with an open turn. `create`, `edit`, `pause`, and `resume` additionally require a direct human message in a runtime-root agent's current turn — a subagent or a non-human producer cannot create or edit goals. `complete` and `blocked` also accept the exact current goal round: a goal-sourced round may complete the goal immediately, but a blocked call is mechanically rejected until the configured number of consecutive rounds has passed — the model judges whether the same condition actually persisted and must describe it in `blocked_reason`. A direct human request may stop a goal immediately.
+
+An autonomous round that successfully reports `complete` or `blocked` also ends the physical turn after that step, and the model receives a closing instruction to write the final message to the user. Direct-human mutations never trigger that stop: the assistant may acknowledge the change and the loop keeps concurrent human steering available.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the tools enforce authority and render output; the observable contract is covered in [Use this package](#use-this-package).
+
+### Design
+
+- **Authority at execution.** Every call resolves the exact live agent, its inherited `AgentRegistry` initiator, running status, and an open turn; `create`, `edit`, `pause`, and `resume` additionally require an accepted `{ kind: 'user' }` message or steering event in a runtime-root agent's current turn. Durable fork lineage does not demote a resumed root; live subagent ownership does.
+- **Host attestation of human input.** `{ kind: 'user' }` is assigned by `Agent.followup()` and `steer()` when their caller omits a source, so plugins, schedulers, and other non-human producers must pass their own source rather than inheriting human authority.
+- **System-prompt guidance with the configured threshold.** The package registers one `tool:goal` system-prompt section whose fixed text interpolates `blockedAfterConsecutiveRounds`; the same value is the hard lower bound enforced at execution.
+- **Wrap-up context for terminal rounds.** A successful autonomous `complete` or `blocked` defers a closing `<goal_complete>` or `<goal_blocked>` instruction so the model addresses the user once before the turn ends; direct-human mutations never defer this context.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: tool registration, config, system-prompt section, result rendering |
+| [`src/authority.ts`](src/authority.ts) | Execution-time authority checks and goal-round acceptance |
+| [`src/wrapup.ts`](src/wrapup.ts) | Closing-message instruction for terminal autonomous updates |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion: empty (no runtime invariant — the goal domain owns accepted mutations) |
+
+### Tool output
+
+All three tools share one canonical output: the compact JSON `{ goal: null }` or `{ goal: { id, revision, objective, phase, roundsStarted, maxGoalRounds, blockedReason? }, activation }`. `activation` in a result is a live observation and never becomes replay authority. UI clients receive pure generic cards — read for `get_goal`, other for mutations.

 [English](README.md) | 中文
 
-[`ctx.goals`](../goal/README.zh.md) 的面向模型控制 API：`get_goal`、`create_goal` 和 `update_goal`。[goal 工具 Agent Note](../../../.agents/notes/implemented/feature/2026-07-19-model-facing-goal-tools.zh.md) 负责权限拆分与 Codex 风格用户体验。
+## 概述
 
-## 工具
+`dsh-tool-goal` 为模型提供基于持久 goal 服务的三个工具：`get_goal` 读取当前 goal，`create_goal` 创建新 goal，`update_goal` 编辑、暂停、恢复、完成或阻塞它。模型可以从人类直接请求中推断长期目标并创建 goal；更新必须携带先前读取到的精确 id 与 revision。权限在执行时强制：create、edit、pause 和 resume 要求顶层 agent 的当前轮次中存在人类直接消息；complete 和 blocked 在自动续行期间还接受当前 Goal Round。可配置的阈值（默认 3）约束自主 Round 多快可以自行报告 `blocked`。当模型需要自行管理 goal 时，与 `dsh-goal` 一起挂载它。
 
-- `get_goal()` 返回当前 goal 或 `null`，包括比较并设置 id／revision、持久 phase、Goal Round 的已准入数／上限、任何 blocker reason，以及当前进程本地续行启用状态。
-- `create_goal(objective, max_goal_rounds?)` 根据人类直接发起的顶层轮次创建一个 goal。模型可以推断长期运行的 goal 意图，而无需精确命令短语；非人类轮次和 subagent 会在执行时被拒绝。
-- `update_goal(goal_id, revision, action, objective?, max_goal_rounds?, blocked_reason?)` 支持 `edit`、`pause`、`resume`、`complete` 和 `blocked`。替换值只属于 `edit`；`blocked_reason` 只有在 action 为 `blocked` 时才必填，并以稳定代码 `model-reported` 持久化。严格 schema 下的空字符串和零填充值视为省略，而有意义的值仍限定到各自 action。
+## 目录
 
-所有调用都互斥，因此模型排序的批次能观察到更早变更及其新 revision。UI 客户端会收到纯通用卡片：`get_goal` 使用 read，变更使用 other。变更卡片选择第一个有意义的 action 值，否则显示 goal id，因此已接受的填充值绝不会产生空输入。

-3 个规范值都与已经渲染给 Native 调用方的紧凑 JSON 一致：`{ goal: null }` 或 `{ goal: { id, revision, objective, phase, roundsStarted, maxGoalRounds, blockedReason? }, activation }`。因此，编程消费方无需解析渲染后的 JSON，即可收到相同领域结构。
+-----
 
-自主 Goal Round 成功报告 `complete` 或 `blocked` 时，会用 `concludeTurn()` 标记该次工具执行，使物理轮次在该步骤后停止。人类直接变更绝不会导致这种停止：assistant 可以确认变更，循环仍可接收并发的人类 steering（中途引导）。

+## 使用本包
 
-## 权限
+当模型需要自行创建和更新持久 goal 时，把 `dsh-tool-goal` 挂在 goal 服务旁边。这些工具是 goal 表面面向模型的一半；`/goal` 命令是面向人类的一半，续行驱动器在自主 Round 结束时使用同一套工具完成或阻塞 goal。
 
-执行要求完全相同的活跃 `exec.agent`、其继承的 `AgentRegistry` initiator、running 状态与开放轮次。create、edit、pause 和 resume 还要求运行时根 agent（智能体）的当前轮次中存在已接受的 `{ kind: 'user' }` 消息或 steering 事件。持久 fork 谱系不会降低已恢复根 agent 的等级；活跃 subagent 所有权会降低。
+### 工具
 
-`{ kind: 'user' }` 是宿主证明。`Agent.followup()` 与 `steer()` 会在调用方省略 source 时分配该值，因此插件、调度器与其他非人类生产方必须传入自己的 source，不能继承用户权限。
+三个工具都返回相同的紧凑 JSON——没有当前 goal 时为 `{ goal: null }`，否则返回 goal 的 id、revision、目标、phase、已开始 Round、Round 上限、可选的 blocker reason 与续行是否已启用——与 Native 调用方已经渲染的内容一致。
 
-complete 与 blocked 还接受完全一致的当前 Goal Round：来源为 goal 的 `user/message`，其 id、revision 和 Round 编号与折叠后的当前 goal 相等。在达到 `blockedAfterConsecutiveRounds` 前，Goal Round 的 blocked 调用会被机械拒绝；模型判断同一条件是否确实持续，并必须在 `blocked_reason` 中说明。人类直接授权可以立即停止 goal。

+- **终局 Round 的结束上下文。** 成功的自主 `complete` 或 `blocked` 会延后一条 `<goal_complete>` 或 `<goal_blocked>` 结束指令，让模型在轮次结束前向用户做一次交代；人类直接变更绝不会延后该上下文。

 # guard/ — loop-hygiene guard family
 
 English | [中文](README.zh.md)
 
-Behavioral guard plugins watch the agent loop for unproductive patterns and enforce per-call budgets. A guard is a self-contained consumer of core services and extension points, not a swappable capability.
+## Summary
 
-| Package | Role | ctx key |
-|---|---|---|
-| [`repeat-tool-reminder/`](repeat-tool-reminder/README.md) | Advisory reminders for repeated tool calls | listens on tool and agent events |
-| [`timeout-policy/`](timeout-policy/README.md) | Arms per-call tool deadlines as deployment policy | registers a `tools/execute` listener |
+The `guard/` group keeps the agent loop productive by watching for two common failure patterns. `repeat-tool-reminder` notices when the model repeats the exact same tool call and reminds it to change approach or finish, so a stuck loop stops burning time and tokens. `timeout-policy` puts a time limit on tool calls that declare one, so a hung call returns a clear timed-out error to the model instead of stalling the session. Both ship enabled in the `dsh` base bundle; a composition can tune or remove them.
 
-Reminders travel as `additionalContexts` on the `tools/post-execute` decision and are appended as logged plugin-sourced `user/message` events ([tools](../../docs/subsystems/tools.md)); the timeout split across `dsh-timeout`, capability termination, and this policy layer is recorded in the [timeout-library Agent Note](../../.agents/notes/implemented/architecture/2026-07-06-timeout-deadline-library.md).

-行为 guard 插件监视 agent loop（智能体循环）中的无效模式，并强制执行单次调用预算。guard 是核心服务和扩展点的自包含消费方，而非可替换能力。
+## 概述
 
-| 包 | 职责 | ctx key |
-|---|---|---|
-| [`repeat-tool-reminder/`](repeat-tool-reminder/README.zh.md) | 针对重复工具调用的建议性提醒 | 监听工具和 agent 事件 |
-| [`timeout-policy/`](timeout-policy/README.zh.md) | 以部署策略形式设置单次工具调用截止时间 | 注册 `tools/execute` 监听器 |
+`guard/` 组通过监视两种常见失败模式来保持 agent loop（智能体循环）高效。`repeat-tool-reminder` 会在模型重复完全相同的工具调用时提醒它改变方法或结束任务，让卡住的循环不再浪费时间和 token。`timeout-policy` 为声明了限时的工具调用设置时间上限，让挂起的调用向模型返回清晰的超时错误，而不是拖住整个会话。两者都随 `dsh` base 组合默认启用；组合可以调优或移除它们。
 
-提醒作为 `additionalContexts` 随 `tools/post-execute` 决策传递，并作为来源于插件的 `user/message` 事件追加记录（[工具](../../docs/subsystems/tools.zh.md)）；跨 `dsh-timeout`、能力终止与本策略层的超时拆分记录在[超时库 Agent Note](../../.agents/notes/implemented/architecture/2026-07-06-timeout-deadline-library.zh.md)。

-An advisory loop-breaker, not a model-facing tool: it never appears in the tool list, never vetoes or rewrites a call, and adds exactly one behavior — it watches each agent's stream of tool calls, counts runs of consecutive calls to the same tool with identical canonicalized arguments, and at configured run lengths injects an escalating advisory reminder telling the model to stop repeating itself, re-read the last result, and either change approach or conclude. The decision (retry differently, gather more evidence, or finish) stays entirely with the model: a legitimately repeated call is delayed by nothing and blocked by nothing. Decision record: [the repeat-tool-reminder Agent Note](../../../.agents/notes/archived/feature/2026-07-08-repeat-tool-guard.md).
+## Summary
 
-## Config
+A model can get stuck calling the same tool with the same arguments — re-running a failing command, re-reading an unchanged file — burning time and tokens without making progress. `dsh-repeat-tool-reminder` notices the pattern and tells the model to stop: at chosen repeat counts it delivers a reminder to analyze the last result and either try a different approach or finish. The reminder is advice, never a block: a legitimate repeated call is delayed by nothing, and the decision to continue, change approach, or stop stays with the model. It tracks each agent separately, so one agent's loop never disturbs another's work, and a new user message clears the count. It ships enabled in the `dsh` base bundle with reminders at 3, 5, and 8 repeats.

+## Use this package
+
+Mount this plugin when the model should catch itself looping on identical tool calls. There is nothing to learn or wire: the `dsh` base bundle already runs it, and the defaults work for most sessions — tune the thresholds and tool scope below when you want the nudge sooner, later, or on fewer tools.
+
+### When to choose it
+
+Choose it when the model works autonomously for long stretches and a stuck loop is the failure you want to break with advice rather than force. Avoid it when identical repeats are legitimate and must run undisturbed — the guard only reminds, and a reminder is a small extra message after the repeated call — and when near-identical variants must be caught, because only exact repeats (same tool, same arguments regardless of property order) are detected.
+
+### Setting the thresholds and scope
+
+When you want to change when reminders fire or which tools they cover, mount the plugin with configuration:
 
 ```yaml
-- id: repeat-tool-reminder
-  name: '@deepseek-ai/dsh-repeat-tool-reminder'
+- name: '@deepseek-ai/dsh-repeat-tool-reminder'
   config:
-    thresholds: [3, 5, 8]        # default; consecutive counts that trigger a reminder
-    include: []                  # tool-name patterns to track; empty ⇒ all tools
-    exclude: [todo_write]        # tool-name patterns transparent to the chain
-    argumentsPreviewChars: 500   # default; cap on arguments quoted in the detailed reminder
+    thresholds: [3, 5, 8]        # remind at 3, 5, and 8 consecutive repeats
+    include: []                  # track every tool; list patterns to track only some
+    exclude: [todo_write]        # never track these tools
+    argumentsPreviewChars: 500   # cap on arguments shown in the detailed reminder
 ```
 
-`thresholds` fails loud at plugin load: an empty list, a non-integer, a value below 2, or a duplicate throws, never a silent fall-back to defaults; `argumentsPreviewChars` equally rejects anything but an integer >= 1. The list is normalized to ascending order; the FIRST threshold delivers a short generic nudge, every later threshold delivers the detailed form naming the tool, the run length, and the canonical arguments — head-truncated at `argumentsPreviewChars` with an omitted-count marker, so a looping `write`/`edit` payload cannot ride into the next request unbounded (the chain key always compares the FULL canonical string; the cap bounds the reminder, never the detection).
+| Field | Default | Meaning |
+|---|---|---|
+| `thresholds` | `[3, 5, 8]` | Repeat counts that trigger a reminder |
+| `include` | `[]` | Only these tools are tracked; empty means every tool |
+| `exclude` | `[]` | These tools are never tracked; calls to them neither count nor reset |
+| `argumentsPreviewChars` | `500` | How many characters of the repeated arguments the detailed reminder shows |
 
-`include`/`exclude` entries support `*` wildcards and are predicates over whatever tools exist at call time, not references to registry entries — a pattern matching no currently registered tool is NOT an error (`exclude: [mcp_*]` stays valid in a deployment that loads no MCP tools), unlike `toolOrder`'s referent check.
+Invalid configuration fails at startup with a clear error — an empty `thresholds` list, a repeat count below 2, or a duplicate — never a silent change of behavior. The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-repeat-tool-reminder) documents every accepted value.
 
-## Chain semantics
+### What you get
 
-The chain key is `(tool name, canonical arguments)` — canonicalization is a deep key-sort plus `JSON.stringify`, so argument objects differing only in property order count as identical. A call identical to the previous tracked call increments the agent's consecutive counter; a different tracked call resets it to 1.
+With the defaults, a model that repeats the same call with identical arguments receives a short reminder on the third repeat — to analyze the previous result before calling again — and detailed reminders on the fifth and eighth, naming the tool and the repeated arguments so it can decide whether to change approach, gather more evidence, or finish. A new user message clears the count, so a fresh instruction is never treated as a loop. Reminders appear in the conversation after the repeated call's result, attributed to the plugin, so the model reads them like any other message.
 
-- **Untracked calls are transparent to the chain.** A call excluded by `include`/`exclude` neither increments nor resets the counter, so `grep X → todo_write → grep X` still counts as two consecutive `grep X` when `todo_write` is excluded. This is what makes exclusion useful: bookkeeping tools interleaved into a loop must not launder it.
-- **Denied calls count.** Detection sits on `tools/post-execute`, which also runs for calls a `tools/pre-execute` listener denied — a model hammering a denied call is exactly the loop worth breaking.

+
+<a id="understand-the-implementation"></a>
+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the guard detects repeats and delivers reminders, and points at the code that realizes it; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The guard is built on four commitments:
+
+- **Advisory, not veto.** The guard enriches post-execute decisions with model context; it never blocks or rewrites a call, so `PostToolDecision` blocking stays a later listener's job.
+- **Count in post-execute.** Detection runs on `tools/post-execute`, which also fires for denied calls; counting there lets one listener cover every attempt with no cross-event state.
+- **Exact-match canonicalization.** Arguments reach the guard as the loop's `JSON.parse` output (or its raw-string fallback), so JSON's value domain is the whole input domain and a deep key-sort plus `JSON.stringify` is a complete, deterministic identity — no bigint, cycle, or `undefined` handling exists because no input path can produce them.
+- **Fail loud at load.** `thresholds` and `argumentsPreviewChars` validate in `apply` and throw, never falling back to defaults.
+
+### Detection: the repeat chain
+
+Each agent's chain is keyed by `(tool name, canonical arguments)` — two calls with the same tool and canonically identical arguments (property order ignored) count as consecutive, and a different tracked call resets the count to 1. The chain lives in a `WeakMap<Agent, Chain>`.
+
+- **Untracked calls are transparent to the chain.** A call excluded by `include`/`exclude` neither increments nor resets the counter, so `grep X → todo_write → grep X` still counts as two consecutive `grep X` when `todo_write` is excluded — bookkeeping tools interleaved into a loop do not launder it.
+- **Denied calls count.** Detection sits on `tools/post-execute`, which also runs for calls a `tools/pre-execute` listener denied; a model hammering a denied call is exactly the loop worth breaking.
 - **Calls without an agent are ignored.** A direct `ctx.tools.execute()` caller has no model to remind and no live agent object to key on.
-- **Per-agent keying.** The tool registry is context-level and subagents interleave through the same waterfall, so a `WeakMap<Agent, Chain>` keys each chain by the live agent object; one agent's repetition never trips another's reminder. A user prompt (`agent/pre-step`) resets the submitting agent's chain, and object lifetime bounds the weak entry without a disposal listener.
-- **In-memory only.** A session resumed from persistence starts with a fresh chain — the guard is a heuristic nudge, not a logged invariant, later reminders are the accepted cost.
+- **Per-agent keying, reset on user prompts.** One agent's repetition never trips another's reminder; a user prompt (`agent/pre-step`) deletes the submitting agent's chain, and object lifetime bounds the weak entry without a disposal listener.
+- **In-memory only.** A session resumed from persistence starts with a fresh chain — the guard is a heuristic nudge, not a logged invariant, so reminders after a resume are the accepted cost.
 
-## Reminder delivery
+### Reminder delivery
 
-Reminders ride the post-execute decision's `additionalContexts` (source `{kind: 'plugin', plugin: 'repeat-tool-reminder'}`), never a `content` replacement: the `tool/result` event stays the tool's own output for audit. The loop buffers the context and appends it as an injected `user/message` after the step's tool results, which the session renders as a plain synthetic user message — so the reminder is model-visible, source-attributed, and reconstructable from the session log with no new session event. The guard always delegates via `next()` and prepends its reminder to the downstream decision's context array (both variants — a blocked call still gets the nudge); every entry retains its own source and metadata.

-这是一个仅提供建议的循环中断器，而非面向模型的工具：它不会出现在工具列表中，不会否决或改写调用，只增加一种行为。它监视每个 agent（智能体）的工具调用流，统计以完全相同的规范化参数连续调用同一工具的次数；达到所配置的连续次数时，它会注入逐级增强的提示，要求模型停止重复、重新阅读上一次结果，并改用其他方案或结束任务。究竟是换一种方式重试、收集更多证据还是完成任务，仍完全由模型决定：合理的重复调用既不会延迟，也不会受阻。决策记录见 [repeat-tool-reminder Agent Note](../../../.agents/notes/archived/feature/2026-07-08-repeat-tool-guard.md)。
+## 概述
 
-## 配置
+模型可能会卡在以相同参数调用同一工具上——反复运行失败的命令、反复读取未变化的文件——白白消耗时间和 token 却没有进展。`dsh-repeat-tool-reminder` 会发现这种模式并让模型停下来：在选定的重复次数上，它送出一条提醒，要求模型分析上一次结果并改用其他方法或结束任务。提醒只是建议，绝非阻止：合理的重复调用不会被延迟分毫，是否继续、改变方法或停止仍由模型决定。它分别跟踪每个 agent（智能体），一个 agent 的循环绝不会干扰另一个 agent 的工作，新的用户消息会清零计数。它随 `dsh` base 组合默认启用，在 3、5、8 次重复时提醒。

+## 使用本包
+
+当模型应当自行发现自己在相同工具调用上循环时，挂载此插件。无需学习或接线：`dsh` base 组合已经运行它，默认值适用于大多数会话——想更早、更晚或在更少的工具上收到提醒时，调优下面的阈值与工具范围即可。
+
+### 何时选择
+
+当模型长时间自主工作、且卡住的循环是你想用建议而非强制来打破的失败模式时，选择它。当相同的重复是合理且必须不受打扰地运行时——guard 只会提醒，提醒只是重复调用之后的一条小消息——以及必须捕获近似变体时（因为只有精确重复——同一工具、同一参数且与属性顺序无关——才会被检测到），避免使用它。
+
+### 设置阈值与范围
+
+想改变提醒何时触发或覆盖哪些工具时，用配置挂载插件：
 
 ```yaml
-- id: repeat-tool-reminder
-  name: '@deepseek-ai/dsh-repeat-tool-reminder'
+- name: '@deepseek-ai/dsh-repeat-tool-reminder'
   config:
-    thresholds: [3, 5, 8]        # default; consecutive counts that trigger a reminder
-    include: []                  # tool-name patterns to track; empty ⇒ all tools
-    exclude: [todo_write]        # tool-name patterns transparent to the chain
-    argumentsPreviewChars: 500   # default; cap on arguments quoted in the detailed reminder
+    thresholds: [3, 5, 8]        # remind at 3, 5, and 8 consecutive repeats
+    include: []                  # track every tool; list patterns to track only some
+    exclude: [todo_write]        # never track these tools
+    argumentsPreviewChars: 500   # cap on arguments shown in the detailed reminder
 ```
 
-插件加载时，`thresholds` 会对错误配置快速失败：空列表、非整数、小于 2 的值或重复值都会抛出错误，绝不静默回退到默认值；`argumentsPreviewChars` 同样只接受大于等于 1 的整数。系统会将列表按升序规范化；第一个阈值只发送简短的通用提醒，后续每个阈值都会发送详细版本，列出工具、连续次数和规范参数。参数内容截取前 `argumentsPreviewChars` 个字符，并附带省略字符数标记，避免循环中的 `write`／`edit` 载荷无限制进入下一次请求（链键始终比较完整的规范字符串；此上限只约束提醒，不影响检测）。
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `thresholds` | `[3, 5, 8]` | 触发提醒的重复次数 |
+| `include` | `[]` | 只跟踪这些工具；空表示所有工具 |

-`include`／`exclude` 条目支持 `*` 通配符，并针对调用时实际存在的工具执行谓词判断，而不是引用注册表条目。因此，与当前任何已注册工具都不匹配的模式并非错误（未加载 MCP 工具的部署中，`exclude: [mcp_*]` 仍然有效）；这与 `toolOrder` 的引用目标检查不同。
+无效配置会在启动时以清晰错误失败——空的 `thresholds` 列表、小于 2 的重复次数或重复值——绝不会静默改变行为。生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-repeat-tool-reminder)记录每个受支持的值。
 
-## 链语义
+### 你会得到什么
 
-链键为「`(tool name, canonical arguments)`」：规范化过程会对键进行深度排序，然后执行 `JSON.stringify`，因此仅属性顺序不同的参数对象会视为相同。若某次调用与上一条受跟踪调用相同，该 agent 的连续计数器递增；换成另一条受跟踪调用则重置为 1。
+按默认值，以相同参数重复同一调用的模型会在第三次重复时收到简短提醒——先分析上一次结果再调用——并在第五次和第八次收到详细提醒，列出工具与重复参数，使其决定改变方法、收集更多证据还是结束任务。新的用户消息会清零计数，因此全新指令绝不会被当作循环。提醒出现在重复调用的结果之后、归属于插件，模型像阅读任何其他消息一样阅读它。
 
-- **不受跟踪的调用对链透明。** 被 `include`／`exclude` 排除的调用既不递增计数器，也不重置计数器；因此，`grep X → todo_write → grep X` 仍算作连续两次 `grep X`，即使 `todo_write` 已被排除。这正是排除机制的价值：循环中穿插的记录类工具不能掩盖循环。
-- **被拒绝的调用也计数。** 检测位于 `tools/post-execute`；即便调用被 `tools/pre-execute` 监听器拒绝，该事件也会运行。模型反复尝试被拒绝的调用，恰恰是需要打断的循环。

+<summary>实现细节——点击展开</summary>
+
+本节解释 guard 如何检测重复并投递提醒，并指出实现它的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+guard 建立在四项承诺之上：
+
+- **仅建议，不否决。** guard 用模型上下文丰富 post-execute 决策；它从不阻止或改写调用，因此 `PostToolDecision` 阻止仍是后续监听器的事。
+- **在 post-execute 中计数。** 检测运行在 `tools/post-execute` 上，被拒绝的调用同样会经过它；在那里计数让一个监听器即可覆盖所有尝试，无需跨事件状态。
+- **精确匹配规范化。** 参数以循环的 `JSON.parse` 输出（或畸形参数 JSON 的原始字符串回退）到达 guard，因此 JSON 的值域就是全部输入域，深度键排序加 `JSON.stringify` 是完整、确定性的同一性判定——不存在 bigint、循环引用或 `undefined` 处理，因为没有输入路径能产生它们。
+- **加载时快速失败。** `thresholds` 与 `argumentsPreviewChars` 在 `apply` 中校验并抛出错误，绝不回退到默认值。
+
+### 检测：重复链
+
+每个 agent 的链以「`(tool name, canonical arguments)`」为键——同一工具且规范化后参数相同（忽略属性顺序）的两次调用计为连续，换成另一条受跟踪调用则把计数重置为 1。链保存在 `WeakMap<Agent, Chain>` 中。
+
+- **不受跟踪的调用对链透明。** 被 `include`／`exclude` 排除的调用既不递增也不重置计数器，因此 `grep X → todo_write → grep X` 在 `todo_write` 被排除时仍算作连续两次 `grep X`——穿插进循环的记录类工具不能掩盖循环。
+- **被拒绝的调用也计数。** 检测位于 `tools/post-execute`，被 `tools/pre-execute` 监听器拒绝的调用同样会经过它；模型反复尝试被拒绝的调用，恰恰是需要打破的循环。
 - **忽略没有 agent 的调用。** 直接调用 `ctx.tools.execute()` 的调用方没有需要提醒的模型，也没有可作为键的活跃 agent 对象。
-- **按 agent 分键。** 工具注册表位于上下文层级，subagent 会交错通过同一个 waterfall（瀑布式事件），因此每条链使用 `WeakMap<Agent, Chain>`，以活跃 agent 对象为键。一个 agent 的重复调用绝不会触发另一个 agent 的提醒。用户提示词（`agent/pre-step`）会重置提交该提示词的 agent 链；对象生命周期会自然限制弱引用条目的寿命，无需 dispose（资源释放）监听器。
-- **仅驻留内存。** 从持久化恢复的会话会从一条全新的链开始：guard 是启发式提醒，并非有日志记录的不变量；提醒会延后，这是可接受的代价。
+- **按 agent 分键，用户提示词时重置。** 一个 agent 的重复绝不会触发另一个 agent 的提醒；用户提示词（`agent/pre-step`）会删除提交该提示词的 agent 链，对象生命周期限制弱引用条目的寿命，无需 dispose（资源释放）监听器。
+- **仅驻留内存。** 从持久化恢复的会话以全新链开始——guard 是启发式提醒，而非记录在案的不变量，因此恢复后的提醒延后是可接受的代价。
 
-## 提醒传递
+### 提醒传递
 
-提醒通过 post-execute 决策中的 `additionalContexts`（来源为 `{kind: 'plugin', plugin: 'repeat-tool-reminder'}`）传递，绝不替换 `content`；用于审计的 `tool/result` 事件仍保留工具自己的输出。循环会缓冲这段上下文，并在该步骤的工具结果之后将其作为注入的 `user/message` 追加；会话会将它渲染为普通的合成用户消息。因此，提醒对模型可见、带有来源归属，并且无需增加会话事件即可从会话日志重建。guard 始终通过 `next()` 委派，并将自己的提醒放在下游决策的上下文数组之前（两种结果都适用：被阻止的调用也会收到提醒）；每个条目保留自己的来源和元数据。

-Tool-call timeout enforcer: a single `tools/execute` around-dispatch listener that arms a per-call cooperative deadline on `exec.signal` for a tool declaring `timeoutMs` on its `ToolDefinition` and returns a structured `TOOL_TIMEOUT` result when that deadline wins. The budget is read from the tool's own declaration (`ToolDefinition.timeoutMs`, set by the owning tool plugin), so this plugin is **zero-config**. It is the reference `tools/execute` wrapper and the enforcement home for model-facing tool-call budgets ([timeout-library Agent Note](../../../.agents/notes/implemented/architecture/2026-07-06-timeout-deadline-library.md)).
+## Summary
 
-## Plugin (namespace: `timeout-policy`)
+A tool call can hang for a long time — a slow web fetch, a search that never returns — and without a limit the model waits indefinitely, stalling the whole session. `dsh-tool-call-timeout-policy` arms a cooperative deadline for calls that declare a limit: it asks the tool to stop through `exec.signal`, then maps a settled cancellation to a clear `Error: tool call timed out after <ms>ms` result. A tool that ignores or slowly handles cancellation keeps the caller waiting until it settles; the plugin never hard-stops downstream work. The limit comes from each tool's own configuration, so the plugin itself is zero-config, and it ships enabled in the `dsh` base bundle.
 
-A function/namespace plugin (`name` / `inject` / `apply`), not a service. It registers no tool and takes no config — it consumes `ctx.tools`'s `tools/execute` waterfall (which the `dsh-tools` registry always provides) and reads each dispatched tool's declared `timeoutMs` from the registry (`ctx.tools.get(exec.name)`).

+## Use this package
+
+The common path is one line: add the plugin to the composition — the `dsh` base bundle already has it. Tools that have a limit configured are protected automatically; every other tool is untouched.
+
+### When to choose it
+
+Choose it when the model calls tools that can take a long time, those tools honor `exec.signal`, and you want a predictable timed-out answer after cancellation settles. Avoid it when a tool must be hard-stopped at its limit — the plugin can only ask a tool to stop, so a tool that ignores cancellation keeps running and keeps the caller waiting — and when you want one default limit for every tool, because each tool's limit comes from that tool's own configuration.
+
+### Setting it up
+
+Mount the plugin with no configuration:
 
 ```yaml
-- id: timeout-policy
-  name: '@deepseek-ai/dsh-tool-call-timeout-policy'
+- name: '@deepseek-ai/dsh-tool-call-timeout-policy'
 ```
 
-The per-tool budget is declared by the tool plugin (e.g. `dsh-tool-web`'s `fetchTimeoutMs`/`searchTimeoutMs` config, attached as `ToolDefinition.timeoutMs`); this plugin only enforces it, so a mistyped tool name is not possible.
+The limit is set where the tool is configured. For example, `dsh-tool-web`'s `fetchTimeoutMs`/`searchTimeoutMs` settings (default 30,000 ms) put the limit on `web_fetch` and `web_search`. Tools without a limit — the shipped `bash`, `read`, `write`, and `edit` — are never cut off. The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-tool-web) lists the tool settings that produce limits.
 
-### Behavior
+### What you get
 
-For a tool that **declares a `timeoutMs`** the listener:
+When the deadline fires, the plugin aborts the derived `exec.signal`. After downstream code honors cancellation and `next()` settles, the model receives `Error: tool call timed out after <ms>ms` as an error result, so it can decide to retry, adjust, or give up. A tool that ignores or slowly handles the signal keeps the caller waiting and produces no timeout result until it settles; calls that finish in time are unchanged.
 
-1. Reads the budget from the tool's own declaration in the registry (`ctx.tools.get(exec.name)?.timeoutMs`) and arms `deadline(exec.signal, timeoutMs, 'TOOL_TIMEOUT')` — one signal fusing the caller's abort with this plugin's timer (`@deepseek-ai/dsh-timeout`).
-2. Swaps that derived signal onto `exec` for the downstream dispatch, then restores the caller's own signal afterward (cordis `next()` ignores passed arguments, so the wrapper mutates the shared `exec` in place; restoring keeps `tools/post-execute` seeing the caller's signal).
-3. After dispatch, if `timeoutOf(d.signal, 'TOOL_TIMEOUT')` matches — this plugin's own timer fired — replaces the result with a structured `TOOL_TIMEOUT` tool result: `{ isError: true, error: { message, info: { name: 'ToolTimeoutError', code: 'TOOL_TIMEOUT' } }, content: 'Error: tool call timed out after <ms>ms' }`.
+-----
 
-A tool that **declares no budget** delegates untouched (no deadline).
+<a id="understand-the-implementation"></a>
+## Understand the implementation
 
-The base `next()` of `tools/execute` is the registry's dispatch-with-normalization thunk, so when the timeout signal reaches a provider that throws its own upstream-abort error, dispatch first turns it into a normal error result, and this wrapper then replaces that with `TOOL_TIMEOUT`. That ordering is why the replacement is keyed off the signal (`timeoutOf`), not off the dispatched result's shape.
+<details>
+<summary>Implementation internals — click to expand</summary>
 
-### Cooperative, not a hard kill
+This section explains how the plugin arms a deadline around each dispatch and maps it to the `TOOL_TIMEOUT` result, and points at the code that realizes it; the observable behavior is fully covered in [Use this package](#use-this-package).
 
-The derived signal only **notifies**; termination stays with the tool and the capability it forwards `exec.signal` to (the `dsh-timeout` library owns no kill). **Declaring `timeoutMs` therefore means "cooperative with `exec.signal`"**: a tool that ignores the signal will not stop on timeout. Only signal-forwarding tools should declare it — the shipped `web_fetch`/`web_search` (which forward through `ctx.web` to providers) are the reference. `TOOL_TIMEOUT` needs no session event for reconstructability: it is the final model-facing `tool/result`, already logged by the loop.
+### Design philosophy
 
-### Composing with other `tools/execute` wrappers
+The wrapper is built on four commitments:
 
-Multiple `tools/execute` listeners compose by cordis registration order. Combined with a future retry/sandbox/metrics wrapper, registration order chooses the semantics — "timeout covers the whole retry operation" (timeout registered outer) versus "timeout covers each attempt" (timeout registered inner).
+- **Enforcement home, not a library.** `dsh-timeout` owns timing and classification (`deadline`, `timeoutOf`); this plugin owns the per-call wiring over `tools/execute`; each capability owns termination. The split is recorded in the [timeout-deadline-library Agent Note](../../../.agents/notes/implemented/architecture/2026-07-06-timeout-deadline-library.md).
+- **The tool declares its own budget.** `timeoutMs` lives on the tool's `ToolDefinition`, read from the registry (`ctx.tools.get(exec.name, exec.agent)?.timeoutMs`), so a mistyped tool name is impossible and undeclared tools delegate untouched.
+- **Scoped classification.** `TOOL_TIMEOUT` serves as both the internal `deadline` classification code and the structured error `code`; scoping `timeoutOf` to it keeps a nested outer deadline (another wrapper's timer that fired first) from being misread as this plugin's timeout — it reads as an ordinary upstream cancel.
+- **Signal swap, then restore.** Cordis `next()` ignores passed arguments, so the wrapper mutates the shared `exec` in place: it swaps the derived deadline signal onto `exec` for dispatch and restores the caller's signal in a `finally`, so `tools/post-execute` listeners never see this plugin's possibly-aborted signal.
 
+### How a deadline is armed and mapped
+
+One `tools/execute` listener reads the dispatched tool's declared limit from the registry (`ctx.tools.get(exec.name, exec.agent)?.timeoutMs`); a tool without a limit delegates untouched. For a limited tool, `deadline(exec.signal, timeoutMs, TOOL_TIMEOUT)` builds a fused signal that the wrapper swaps onto `exec` for dispatch and restores in a `finally`, so `tools/post-execute` listeners never see the derived signal. When the wrapper's own timer fired — `timeoutOf(d.signal, 'TOOL_TIMEOUT')` scoped by the code, so a nested outer deadline reads as an ordinary upstream cancel — the dispatched result, already normalized into an error result by dispatch, is replaced with the structured result: `isError: true`, content `Error: tool call timed out after <ms>ms`, and error info `{ name: 'ToolTimeoutError', code: 'TOOL_TIMEOUT' }`.
+
+### Composing with other wrappers
+
+Multiple `tools/execute` listeners compose by Cordis registration order, which chooses the semantics: the timeout registered outer covers a whole retry operation, the timeout registered inner covers each attempt.

-工具调用超时强制执行器：单个 `tools/execute` 环绕分发监听器，会在 `exec.signal` 上设置单次调用的协作式截止时间；适用于声明了 `timeoutMs` 且声明位于其 `ToolDefinition` 上的工具。该截止时间先到时，它返回结构化 `TOOL_TIMEOUT` 结果。预算从工具自身的声明中读取（`ToolDefinition.timeoutMs`，由拥有该工具的插件设置），因此此插件是**零配置**的。它是 `tools/execute` 包装层的参考实现，也是面向模型工具调用预算的强制执行归属地（[超时库 Agent Note](../../../.agents/notes/implemented/architecture/2026-07-06-timeout-deadline-library.zh.md)）。
+## 概述
 
-## 插件（命名空间：`timeout-policy`）
+工具调用可能会长时间挂起——缓慢的网页抓取、永不返回的搜索——没有上限时模型会无限期等待，拖住整个会话。`dsh-tool-call-timeout-policy` 为声明了限时的调用设置协作式截止时间：它通过 `exec.signal` 请求工具停止，再把已经完成的取消映射为清晰的 `Error: tool call timed out after <ms>ms` 结果。忽略或缓慢处理取消的工具会让调用方继续等待，直到自身完成；本插件绝不会硬性停止下游工作。限时来自每个工具自身的配置，因此插件本身零配置，并随 `dsh` base 组合默认启用。
 
-它是函数／命名空间插件（`name`／`inject`／`apply`），而非服务。它不注册工具，也不接受配置；它消费 `ctx.tools` 的 `tools/execute` waterfall（瀑布式事件）（由 `dsh-tools` 注册表始终提供），并读取每个已分发工具声明的 `timeoutMs`；该声明来自注册表（`ctx.tools.get(exec.name)`）。

+当模型会调用耗时很长的工具、这些工具会遵守 `exec.signal`，且你希望在取消完成后得到可预期的超时答复时，选择它。当工具必须在到达限时后被硬性停止时——插件只能请求工具停止，因此忽略取消的工具会继续运行并让调用方继续等待——以及当你希望为所有工具设置一个统一默认限时时（因为每个工具的限时来自该工具自身的配置），避免使用它。
+
+### 设置
+
+无需任何配置即可挂载插件：
 
 ```yaml
-- id: timeout-policy
-  name: '@deepseek-ai/dsh-tool-call-timeout-policy'
+- name: '@deepseek-ai/dsh-tool-call-timeout-policy'
 ```
 
-每工具预算由工具插件声明（例如 `dsh-tool-web` 的 `fetchTimeoutMs`／`searchTimeoutMs` 配置，会附加为 `ToolDefinition.timeoutMs`）；此插件只负责强制执行，因此不可能拼错工具名。
+限时在配置工具的位置设置。例如，`dsh-tool-web` 的 `fetchTimeoutMs`／`searchTimeoutMs` 设置（默认 30,000 ms）把限时放到 `web_fetch` 与 `web_search` 上。没有限时的工具——随附的 `bash`、`read`、`write`、`edit`——绝不会被切断。生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-tool-web)列出会产生限时的工具设置。
 
-### 行为
+### 你会得到什么
 
-对 **声明了 `timeoutMs` 的工具**，监听器会：
+截止时间触发时，插件会中止派生的 `exec.signal`。下游代码遵守取消且 `next()` 完成后，模型会收到标记为错误的 `Error: tool call timed out after <ms>ms` 工具结果，从而决定重试、调整或放弃。忽略或缓慢处理该信号的工具会让调用方继续等待，并且在自身完成前不会产生超时结果；按时完成的调用保持不变。
 
-1. 从注册表中的工具自身声明（`ctx.tools.get(exec.name)?.timeoutMs`）读取预算，并设置 `deadline(exec.signal, timeoutMs, 'TOOL_TIMEOUT')`：一个将调用方中止与此插件计时器融合的信号（`@deepseek-ai/dsh-timeout`）。
-2. 将该派生信号替换到 `exec` 上用于下游分发，然后恢复调用方自身的信号（Cordis `next()` 忽略传入的参数，因此包装层会原地修改共享 `exec`；恢复可使 `tools/post-execute` 看到调用方的信号）。
-3. 分发后，如果 `timeoutOf(d.signal, 'TOOL_TIMEOUT')` 检测到此插件自身的计时器已触发，则将结果替换为结构化 `TOOL_TIMEOUT` 工具结果：`{ isError: true, error: { message, info: { name: 'ToolTimeoutError', code: 'TOOL_TIMEOUT' } }, content: 'Error: tool call timed out after <ms>ms' }`。
+-----
 
-**未声明预算的工具** 会原样委托（不启动截止时间）。
+<a id="understand-the-implementation"></a>
+## 理解实现
 
-基础 `next()` 是注册表为 `tools/execute` 提供的、带规范化处理的分发 thunk，因此当超时信号到达抛出自身上游中止错误的提供方时，分发会先将其转换为普通错误结果，再由此包装层替换为 `TOOL_TIMEOUT`。这一顺序就是替换依据信号（`timeoutOf`）而非已分发结果形状的原因。
+<details>
+<summary>实现细节——点击展开</summary>
 
-### 协作式，而非硬终止
+本节解释插件如何在每次分发周围设置截止时间并将其映射为 `TOOL_TIMEOUT` 结果，并指出实现它的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
 
-派生信号只会**通知**；是否终止仍取决于工具及其将 `exec.signal` 转发到的能力（`dsh-timeout` 库本身不负责硬终止）。**因此，声明 `timeoutMs` 意味着「与 `exec.signal` 协作」**：忽略该信号的工具不会在超时时停止。只有转发信号的工具才应声明该字段；已交付的 `web_fetch`／`web_search`（通过 `ctx.web` 转发给提供方）是参考实现。`TOOL_TIMEOUT` 无需会话事件以满足可重建性：它是最终面向模型的 `tool/result`，已由循环记录。
+### 设计理念
 
-### 与其他 `tools/execute` 包装层组合
+包装层建立在四项承诺之上：
 
-多个 `tools/execute` 监听器按 Cordis 注册顺序组合。与未来的重试／沙箱／指标包装层一起使用时，注册顺序决定语义：「超时覆盖整个重试操作」（超时注册在外层），或「超时覆盖每次尝试」（超时注册在内层）。
+- **强制执行归属，而非库。** `dsh-timeout` 负责时序与分类（`deadline`、`timeoutOf`）；本插件负责 `tools/execute` 上的单次调用接线；各能力负责终止。该拆分记录在[超时截止时间库 Agent Note](../../../.agents/notes/implemented/architecture/2026-07-06-timeout-deadline-library.zh.md) 中。
+- **工具声明自己的预算。** `timeoutMs` 位于工具的 `ToolDefinition` 上，从注册表读取（`ctx.tools.get(exec.name, exec.agent)?.timeoutMs`），因此不可能拼错工具名，未声明工具原样委派。
+- **作用域分类。** `TOOL_TIMEOUT` 同时用作内部 `deadline` 分类码与结构化错误 `code`；把 `timeoutOf` 限定到它，可避免嵌套的外层截止时间（先触发的另一包装层计时器）被误读为本插件的超时——它读作普通的上游取消。
+- **先交换信号，再恢复。** Cordis `next()` 忽略传入参数，因此包装层原地修改共享 `exec`：分发时把派生的截止时间信号换到 `exec` 上，并在 `finally` 中恢复调用方信号，使 `tools/post-execute` 监听器永远看不到本插件可能已中止的信号。
 
+### 截止时间如何设置与映射
+
+一个 `tools/execute` 监听器从注册表读取已分发工具声明的限时（`ctx.tools.get(exec.name, exec.agent)?.timeoutMs`）；没有限时的工具原样委派。对有限时的工具，`deadline(exec.signal, timeoutMs, TOOL_TIMEOUT)` 构建融合信号，包装层在分发时把它换到 `exec` 上并在 `finally` 中恢复，使 `tools/post-execute` 监听器永远看不到派生信号。当包装层自己的计时器触发时——`timeoutOf(d.signal, 'TOOL_TIMEOUT')` 以代码限定作用域，因此嵌套的外层截止时间读作普通的上游取消——已被分发规范化为错误结果的分发结果会被替换为结构化结果：`isError: true`、内容 `Error: tool call timed out after <ms>ms`、错误信息 `{ name: 'ToolTimeoutError', code: 'TOOL_TIMEOUT' }`。
+
+### 与其他包装层组合
+
+多个 `tools/execute` 监听器按 Cordis 注册顺序组合，注册顺序决定语义：超时注册在外层时覆盖整个重试操作，注册在内层时覆盖每次尝试。

-The hooks subsystem lets users extend the agent at lifecycle points the way Claude Code and Codex do — by pointing a bridge plugin at an existing `hooks.json` (or settings) so those external shell hooks run faithfully. The canonical extension surface itself is the harness's typed interception points ([the interception extension-points Agent Note](../../.agents/notes/implemented/feature/2026-06-30-interception-extension-points.md)); a "native hook" is just an ordinary Cordis plugin on those extension points. These packages are the **bridges** that translate the external shell-hook protocol onto that same surface, plus the shared wire-protocol library they build on.
+## Summary
+
+The hooks group lets agent runs use the shell hooks you already wrote for Claude Code or Codex: mount the matching bridge, point it at your existing `hooks.json`, and those hooks fire at the corresponding moments in agent runs — when a session starts, when a prompt is submitted, before and after a tool runs, or when a run is about to stop. Hooks can block a prompt or tool call with a message the model sees, attach extra context to the conversation, or force the run to continue. Choose this group when existing hook configs should keep working without being rewritten as native plugins; each bridge covers the command-hook subset its reference tool documents. `hook-protocol` is the shared hook engine both bridges use, so the two dialects behave the same way where their protocols agree.

-hooks 子系统让用户像使用 Claude Code 和 Codex 一样，在生命周期节点扩展 agent（智能体）：把桥接插件指向现有 `hooks.json`（或设置），即可忠实运行这些外部 shell 钩子。规范扩展接口本身是 harness 的类型化拦截点（参见[拦截扩展点 Agent Note](../../.agents/notes/implemented/feature/2026-06-30-interception-extension-points.zh.md)）；「原生钩子」只是这些扩展点上的普通 Cordis 插件。这些包是把外部 shell 钩子协议转换到同一接口的**桥接**，也包括它们共同依赖的共享协议库。
+## 概述
+
+hooks 组让 agent（智能体）运行可以使用你为 Claude Code 或 Codex 写好的 shell 钩子：挂载对应的桥接、把它指向你现有的 `hooks.json`，这些钩子就会在 agent 运行中的对应时刻触发——会话开始时、提示词提交时、工具运行前后，或运行即将停止时。钩子可以带一条模型可见的消息阻塞提示词或工具调用、向对话附加额外上下文，或强制运行继续。当你希望现有钩子配置无需改写成原生插件就能继续工作时，选择本组；每个桥接覆盖其参考工具文档中的 command hook 子集。`hook-protocol` 是两个桥接共享的钩子引擎，因此两种方言在协议一致之处行为相同。

 # @deepseek-ai/dsh-hook-protocol
 
 English | [中文](README.zh.md)
 
-The **shared core** of the Claude Code / Codex hook wire protocol. NOT a cordis plugin — it registers nothing and injects nothing. It is a **library** of dialect-neutral primitives the two bridge plugins (`@deepseek-ai/dsh-hooks-claude-code`, `@deepseek-ai/dsh-hooks-codex`) import so neither re-implements the identical halves of the protocol.
+## Summary
 
-Codex deliberately reimplements a *subset* of the Claude Code hook protocol — the same `hooks.json` matcher-group shape, the same exit-code/stdout output contract, the same command-hook execution model. The genuinely-shared parts live here; each bridge owns only what differs.
+`dsh-hook-protocol` makes both bridges handle your hooks identically: it defines what a hook can do and what happens when it runs. You never install or configure it yourself — choose `dsh-hooks-claude-code` or `dsh-hooks-codex`, point it at your existing `hooks.json`, and these rules apply to your hooks. Through either bridge, a hook can block a prompt or tool call with a message the model sees, attach extra context to the conversation, or ask the run to stop. Only command hooks run; `http`, `mcp_tool`, `prompt`, and `agent` handlers are skipped with a warning.
 
-## What's shared (here) vs. per-dialect (the bridges)
+## Table of Contents
 
-| Concern | Here (`dsh-hook-protocol`) | The bridge (`dsh-hooks-claude-code` / `-codex`) |
-|---|---|---|
-| Matcher validation + test | `matcherDiagnostic(pattern, mode)` for parse-time diagnostics; `matchesMatcher(pattern, query, mode)` for contained runtime matching | picks its `mode` (`claude` = literal-or-regex, `codex` = always regex) and rejects a config group carrying a diagnostic |
-| Run a hook | `runHook(bash, hook, opts, now)` — stdin payload + env via `ctx.shell`, decode | builds the per-event stdin **payload** + the dialect's **env** |
-| Decode output | `parseHookOutput(exit, stdout, stderr)` → neutral `HookOutput` | maps the neutral `HookOutput` onto an extension-point-specific typed Decision |
-| Merge N hooks | `mergeHookOutputs(outputs)` → most-restrictive `MergedHookOutcome` | — |
-| Durable record | `appendHookInvoked` / `appendHookResult` (`hook/*` session events; the result's `decision`/`stderrSummary` derive from the `HookOutput` here) | calls them around each invocation |
-| Detached-run quiescence | `createDetachedRuns()` — track fire-and-forget run chains; `drain()` aborts, then awaits them | passes `signal` to each detached `runHook`, registers `drain` as its effect disposer |

-## Primitives
+-----
 
-- **`matcherDiagnostic(matcher, mode)` / `matchesMatcher(matcher, query, mode)`** — match-all on absent/`''`/`'*'`; `claude` mode treats a pure `[A-Za-z0-9_|]+` pattern as a literal (pipe = exact-match alternation) and anything else as a regex; `codex` mode is always an unanchored regex. Bridge parsers discard matcher fields for events without matcher subjects, then use `matcherDiagnostic` to reject an invalid consumed regex with a stable diagnostic before registering any hooks. The runtime predicate still contains an invalid pattern as a non-match, so a direct library caller cannot throw into the agent loop.
-- **`runHook(bash, hook, options, now)`** — require and forward the caller-owned `options.signal`, serialize `options.payload` to the hook's stdin (with a trailing newline iff `options.trailingNewline`), merge `options.env` after the executor's credential scrub (the `dsh-shell` trusted-plugin API), honor the hook's `timeoutSec` (else `options.defaultTimeoutMs` — the bridge owns the default, its config defaulting to the lib's `DEFAULT_HOOK_TIMEOUT_MS` 10-minute reference), and decode the result (threading `options.expectedEventName` to the codec). Cancellation therefore reaches the executor's process-group kill and join boundary. Never throws: an executor rejection (infra fault) becomes a `HookOutput` with `exitCode: undefined` (a non-blocking error). `now` is injected for testable durations.
-- **`parseHookOutput(exitCode, stdout, stderr, expectedEventName?)`** decodes exit status and structured stdout. Exit 2 blocks with stderr; other failures are non-blocking. A matching hook-specific permission decision overrides the legacy top-level decision; mismatched or missing event discriminators suppress only event-specific fields. Top-level fields remain event-agnostic, and successful non-JSON output is left to the bridge.
-- **`mergeHookOutputs(outputs)`** — fold the results of every hook that matched one point: permission precedence **deny > ask > allow**, halt sticky on the first `continue:false`, block reasons joined with `\n\n`, `additionalContext`/`systemMessages` accumulated in order.
-- **`createDetachedRuns()`** — quiescence tracking for the emit-shaped points, which run detached (no extension point awaits them). The bridge tracks each run chain — the hook run PLUS its continuation — and registers `drain()` as its effect disposer: drain fires the tracker's abort `signal` (so a still-running hook process is killed via `runHook`, not awaited out to its timeout), then resolves once every tracked chain has settled. `fiber.dispose()` resolving therefore means no detached hook work is left to fire into a disposed context ([defensive patterns](../../../docs/defensive-patterns.md): dispose must reach quiescence).
+<a id="use-this-package"></a>
+## Use this package
 
-## `hook/*` session events
+You don't install or configure this package directly — mounting `dsh-hooks-claude-code` or `dsh-hooks-codex` applies these rules to your existing `hooks.json` hooks. Use this page to learn what a hook can do and what happens when it runs; the two bridge pages list which events each dialect supports.
 
-Declaration-merged into `SessionEventMap` (log-only, like `compaction/*` — NOT a `SurfaceEventType`, no `surfaceOp`): `hook/invoked` (a hook command ran) and `hook/result` (its outcome, paired by `handlerId`, with `appendHookResult` owning the decision rule). Payloads and per-event JSDoc are in the generated [persistence log event catalog](../../../docs/persistence-catalog.md); `stderrSummary` is truncated to the record's `stderrSummaryMaxChars` (the bridge's config, reference default `DEFAULT_STDERR_SUMMARY_MAX_CHARS` = 500; omitted when empty).
+### When to choose it
 
-Hook invocation/result records must sit inside an open turn. `UserPromptSubmit`, `PreToolUse`, `PostToolUse`, and `Stop` satisfy that owner-defined relation by construction. `SessionStart` runs before turn 1 and gets no `hook/*` record; its allowed context remains pending in the inbox until a waking delivery opens a turn — see the hooks Agent Note.
+Choose `dsh-hooks-claude-code` or `dsh-hooks-codex` when you have existing Claude Code or Codex hooks and want them to keep working during agent runs. You never choose this package directly. Avoid the whole group for bespoke behavior with no reference-tool equivalent: a native Cordis plugin has the full harness API with no hook protocol in between.
 
+### What a hook can do
+
+- **Block an action with a message** — a hook that exits with code 2 stops the prompt or tool call, and its error output is shown as the reason.
+- **Ask before a tool runs** — a Claude Code hook can request confirmation instead of blocking outright; the Codex bridge does not surface this option.
+- **Attach context** — a hook can return extra text that the model sees in the next request.
+- **Run on chosen moments** — a hook config selects which events it fires on by name or pattern; an absent, empty, or `'*'` pattern means every event of that kind.
+- **Fail without stopping the run** — any exit code other than 2 is a non-blocking failure: the action proceeds and the failure is logged, and a hook that cannot be started at all is treated the same way.
+- **Ask the run to stop** — a hook can request that the run halt (`{"continue": false}`); the request is recorded but has no run-level effect (see Known Limitations).
+
+### What you see when hooks run
+
+- When a hook blocks, the action does not happen and the hook's message is shown.
+- When a hook attaches context, the model sees that text in its next request.
+- A hook that fails — a bad command, a crash, or any exit other than 2 — is logged and does not stop the agent.
+- If the hook config cannot be read or parsed, the bridge logs a warning and no hooks run; the agent still starts.
+- Configs that mix hook types still work: `http`, `mcp_tool`, `prompt`, and `agent` handlers are skipped with a warning, and their command hooks run.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the library and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Processing pipeline
+
+The library is a chain of single-purpose steps, one function each: validate the matcher pattern, run the command through the `dsh-shell` executor, decode the outcome, merge every matched hook's outcome into one most-restrictive result, and record the durable `hook/*` event pair. The matcher's `mode` parameter is the single axis the dialects differ on — `claude-code` interprets a pattern as literal alternatives or a regex, `codex` always as an unanchored regex. Every step degrades to a contained outcome instead of throwing, so a hook can never crash the calling turn: an invalid regex is a non-match, an executor rejection becomes a `HookOutput` with no exit code, exit 2 blocks with stderr as the reason, and every other failure stays non-blocking. Merging applies `deny > ask > allow` precedence, keeps the first `continue: false` stop sticky, and accumulates context in hook order. Detached runs are tracked so `fiber.dispose()` reaches quiescence, and the invariant companion rejects `hook/*` records outside an open turn. The steps live in [`src/matcher.ts`](src/matcher.ts), [`src/runner.ts`](src/runner.ts), [`src/codec.ts`](src/codec.ts), [`src/merge.ts`](src/merge.ts), [`src/events.ts`](src/events.ts), [`src/detached.ts`](src/detached.ts), and [`src/invariant.ts`](src/invariant.ts).
+
+### `hook/*` session events
+
+The `hook/invoked` and `hook/result` events are declaration-merged into `SessionEventMap` as log-only records: like `compaction/*`, they are not surface events and carry no `surfaceOp`. A `hook/result` pairs with its `hook/invoked` by `handlerId`, and `appendHookResult` owns the decision rule. Payloads and per-event JSDoc live in the generated [persistence log event catalog](../../../docs/persistence-catalog.md).
+
+Invocation and result records must sit inside an open turn: `UserPromptSubmit`, `PreToolUse`, `PostToolUse`, and `Stop` satisfy that relation by construction, while `SessionStart` runs before turn 1 and gets no `hook/*` record — its injected context is delivered instead. The invariant companion registers on `ctx.invariants` and rejects `hook/*` events appended outside an open turn, a result without a matching invoked, an unknown dialect, or a non-finite duration.
+
+### Design philosophy
+
+- **One axis of difference collapsed into `mode`.** The dialects differ only in how a matcher pattern is interpreted, so the matcher takes the mode as a parameter instead of duplicating the engine.
+- **The executor owns process control.** Commands run through the `dsh-shell` executor rather than a bespoke spawn: the executor already provides the scrubbed-but-overridable environment, process-group cancellation, and timeout the protocol needs.
+- **Never throw into the loop.** Every failure mode — malformed JSON, an invalid regex, an executor rejection — degrades to a contained outcome or a non-match, so a hook can never crash the calling turn.
+- **Log-only, turn-enclosed events.** The `hook/*` records are durable evidence of what ran and what it decided; they are not surface events, and the invariant companion rejects them outside an open turn.
+
+The [hook-protocol-lib Agent Note](../../../.agents/notes/implemented/feature/2026-06-30-hook-protocol-lib.md) records the shared-versus-per-dialect split and the alternatives considered.

+#### Future: run-level halt
+
+A hook that asks to halt the whole run (`continue: false`) is folded into `MergedHookOutcome.stop` but not applied anywhere: the interception points lack a hard-halt primitive, and mid-turn requests record the halt in `hook/result` instead.

 # @deepseek-ai/dsh-hook-protocol
 
 [English](README.md) | 中文
 
-Claude Code／Codex hook 协议格式（wire format）的**共享核心**。它不是 Cordis 插件：不注册也不注入任何内容。它是一个**库**，提供两个桥接插件（`@deepseek-ai/dsh-hooks-claude-code`、`@deepseek-ai/dsh-hooks-codex`）导入的方言无关原语，使两者都无需重复实现协议中相同的部分。
+## 概述
 
-Codex 有意重新实现了 Claude Code hook 协议的一个*子集*，包括相同的 `hooks.json` matcher group 结构、相同的退出码／stdout 输出约定以及相同的 command hook 执行模式。真正共享的部分位于此处；每个桥接只负责不同的部分。
+`dsh-hook-protocol` 让两个桥接以相同方式处理你的钩子：它定义钩子能做什么、运行时会发生什么。你无需自行安装或配置它——选择 `dsh-hooks-claude-code` 或 `dsh-hooks-codex`，把它指向你现有的 `hooks.json`，这些规则就会作用于你的钩子。通过任一桥接，钩子都可以带一条模型可见的消息阻塞提示词或工具调用、向对话附加额外上下文，或请求运行停止。只有 command 钩子会运行；`http`、`mcp_tool`、`prompt` 与 `agent` handler 会被跳过并给出警告。
 
-## 共享内容（此处）与各方言内容（桥接）
+## 目录
 
-| 关注点 | 此处（`dsh-hook-protocol`） | 桥接（`dsh-hooks-claude-code` / `-codex`） |
-|---|---|---|
-| Matcher 校验与匹配判断 | `matcherDiagnostic(pattern, mode)` 用于解析时诊断；`matchesMatcher(pattern, query, mode)` 用于隔离的运行时匹配 | 选择自身的 `mode`（`claude` = 字面量或正则，`codex` = 始终使用正则），并拒绝带有诊断的配置组 |
-| 运行 hook | `runHook(bash, hook, opts, now)`：通过 `ctx.shell` 提供 stdin payload + env，再解码 | 构造每个事件的 stdin **payload** + 该方言的 **env** |
-| 解码输出 | `parseHookOutput(exit, stdout, stderr)` → 中性 `HookOutput` | 将中性 `HookOutput` 映射到扩展点特定的类型化 Decision |
-| 合并 N 个 hook | `mergeHookOutputs(outputs)` → 最严格的 `MergedHookOutcome` | （无） |
-| 持久记录 | `appendHookInvoked` / `appendHookResult`（`hook/*` 会话事件；结果的 `decision`／`stderrSummary` 从此处的 `HookOutput` 派生） | 在每次调用前后调用它们 |
-| 脱离运行的完全停稳 | `createDetachedRuns()`：跟踪触发后不等待的运行链；`drain()` 先 abort，再等待它们 | 将 `signal` 传给每个脱离的 `runHook`，并将 `drain` 注册为 effect disposer |

-## 原语
+-----
 
-- **`matcherDiagnostic(matcher, mode)` / `matchesMatcher(matcher, query, mode)`**：缺失、`''` 或 `'*'` 时匹配全部；`claude` mode 将纯 `[A-Za-z0-9_|]+` pattern 视为字面量（管道符 = 精确匹配交替），其他 pattern 视为正则；`codex` mode 始终使用未锚定正则。桥接解析器会丢弃没有 matcher 匹配对象的事件所带的 matcher 字段，再用 `matcherDiagnostic` 拒绝事件实际使用的无效正则，并在注册任何钩子之前给出稳定诊断。运行时谓词仍会将无效 pattern 隔离为不匹配，因此直接调用本库不会向 agent loop（智能体循环）抛异常。
-- **`runHook(bash, hook, options, now)`**：要求并转发调用方拥有的 `options.signal`，将 `options.payload` 序列化到 hook stdin（当且仅当 `options.trailingNewline` 时添加尾随换行符），在执行器凭证清理后合并 `options.env`（`dsh-shell` 受信任插件接口），遵循 hook 的 `timeoutSec`（否则使用 `options.defaultTimeoutMs`；默认值属于桥接，其配置默认为 lib 的 `DEFAULT_HOOK_TIMEOUT_MS` 10 分钟参考值），再解码结果（将 `options.expectedEventName` 传递给 codec）。因此取消会到达执行器的进程组终止与 join 边界。它绝不抛出异常：执行器拒绝（基础设施故障）会变为 `HookOutput`，其 `exitCode: undefined`（非阻塞错误）。`now` 会被注入，以便测试持续时间。
-- **`parseHookOutput(exitCode, stdout, stderr, expectedEventName?)`** 解码退出状态与结构化 stdout。退出码为 2 时，会以 stderr 内容阻止执行；其他失败不阻塞。匹配的 hook 特定权限决策会覆盖遗留顶层决策；事件判别字段不匹配或缺失只会抑制事件特定字段。顶层字段仍与事件无关，成功但非 JSON 的输出会留给桥接处理。
-- **`mergeHookOutputs(outputs)`**：折叠在一个点上匹配的每个 hook 结果：权限优先级为 **deny > ask > allow**，从首个 `continue:false` 起，halt 状态保持不变，阻塞原因用 `\n\n` 连接，`additionalContext`／`systemMessages` 按顺序累积。
-- **`createDetachedRuns()`**：跟踪以 emit 形式脱离运行的点是否完全停稳（没有扩展点等待它们）。桥接会跟踪每条运行链，包括 hook 运行及其 continuation，并将 `drain()` 注册为 effect disposer。drain 会触发 tracker 的 abort `signal`（因此仍在运行的 hook 进程会通过 `runHook` 终止，而不是等待到超时），随后在所有已跟踪链结算后 resolve。因此 `fiber.dispose()` resolve 时，不会遗留任何可能作用于已 dispose（资源释放）的上下文的脱离 hook 工作（见 [防御模式](../../../docs/defensive-patterns.zh.md)：dispose 必须达到完全停稳）。

+## 使用本包
 
-## `hook/*` 会话事件
+你无需直接安装或配置本包——挂载 `dsh-hooks-claude-code` 或 `dsh-hooks-codex` 就会把这些规则应用到你的 `hooks.json` 钩子上。用本页了解钩子能做什么、运行时会发生什么；两个桥接页面列出各方言支持的事件。
 
-通过 declaration merging 合并到 `SessionEventMap`（仅日志，与 `compaction/*` 相同；不是 `SurfaceEventType`，没有 `surfaceOp`）：`hook/invoked`（hook 命令已运行）与 `hook/result`（其结果，按 `handlerId` 配对，决策规则由 `appendHookResult` 负责）。Payload 与每事件 JSDoc 位于生成的 [持久化日志事件目录](../../../docs/persistence-catalog.zh.md)；`stderrSummary` 会截断到记录的 `stderrSummaryMaxChars`（桥接配置，参考默认值 `DEFAULT_STDERR_SUMMARY_MAX_CHARS` = 500；为空时省略）。
+### 何时选择
 
-Hook 调用／结果记录必须位于一个尚未结束的轮次内。`UserPromptSubmit`、`PreToolUse`、`PostToolUse` 与 `Stop` 按构造满足这条由所有者定义的关系。`SessionStart` 在轮次 1 之前运行，因此没有 `hook/*` 记录；其获准的上下文会在 inbox 中保持待处理，直到唤醒交付打开一个轮次，详见 hooks Agent Note。
+当你持有现有的 Claude Code 或 Codex 钩子、希望它们在 agent（智能体）运行期间继续工作时，选择 `dsh-hooks-claude-code` 或 `dsh-hooks-codex`。你永远不会直接选择本包。没有参考工具对应物的定制行为请避开整个组：原生 Cordis 插件拥有完整的 harness API，无需中间的钩子协议。
 
+### 钩子能做什么
+
+- **带消息阻塞操作**——退出码为 2 的钩子会停止提示词或工具调用，其错误输出会作为原因展示。
+- **工具运行前请求确认**——Claude Code 钩子可以请求确认而非直接阻塞；Codex 桥接不呈现此选项。
+- **附加上下文**——钩子可以返回额外文本，模型会在下一次请求中看到。
+- **在选定时刻运行**——钩子配置按名称或 pattern 选择触发的事件；缺失、空或 `'*'` pattern 表示该类的每个事件。
+- **失败不停止运行**——除 2 以外的任何退出码都是非阻塞失败：操作继续，失败被记录；完全无法启动的钩子按同样方式处理。
+- **请求运行停止**——钩子可以请求运行暂停（`{"continue": false}`）；该请求会被记录，但没有运行级效果（见已知限制）。
+
+### 钩子运行时你会看到什么
+
+- 钩子阻塞时，操作不会发生，钩子的消息会被展示。
+- 钩子附加上下文时，模型会在下一次请求中看到该文本。
+- 失败的钩子——命令错误、崩溃或除 2 以外的任何退出码——会被记录，不会停止 agent。
+- 如果钩子配置无法读取或解析，桥接会记录警告且不运行任何钩子；agent 仍会启动。
+- 混合钩子类型的配置仍然可用：`http`、`mcp_tool`、`prompt` 与 `agent` handler 会被跳过并给出警告，其 command 钩子照常运行。

+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释本库背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 处理流水线
+
+本库是一串单一用途的步骤，每个步骤一个函数：校验 matcher pattern、通过 `dsh-shell` 执行器运行命令、解码结果、把每个匹配 hook 的结果合并为最严格的一个结果，并记录持久的 `hook/*` 事件对。matcher 的 `mode` 参数是两个方言唯一的差异轴——`claude-code` 把 pattern 解释为字面量备选或正则，`codex` 始终解释为未锚定正则。每个步骤都会降级为受控结果而不是抛异常，因此钩子永远不会使调用轮次崩溃：无效正则是运行时的不匹配，执行器拒绝会变成没有退出码的 `HookOutput`，退出码 2 以 stderr 作为原因阻塞，其他失败均不阻塞。合并应用 `deny > ask > allow` 优先级，保持首个 `continue: false` 停止的粘性，并按 hook 顺序累积上下文。脱离运行会被跟踪，因此 `fiber.dispose()` 能达到完全停稳；不变式伴生插件会拒绝未开启轮次外的 `hook/*` 记录。这些步骤位于 [`src/matcher.ts`](src/matcher.ts)、[`src/runner.ts`](src/runner.ts)、[`src/codec.ts`](src/codec.ts)、[`src/merge.ts`](src/merge.ts)、[`src/events.ts`](src/events.ts)、[`src/detached.ts`](src/detached.ts) 与 [`src/invariant.ts`](src/invariant.ts)。
+
+### `hook/*` 会话事件
+
+`hook/invoked` 与 `hook/result` 事件通过 declaration merging 合并进 `SessionEventMap`，作为仅日志记录：与 `compaction/*` 相同，它们不是 surface 事件，也不携带 `surfaceOp`。`hook/result` 按 `handlerId` 与其 `hook/invoked` 配对，决策规则由 `appendHookResult` 负责。载荷与逐事件 JSDoc 位于生成的[持久化日志事件目录](../../../docs/persistence-catalog.zh.md)中。
+
+调用与结果记录必须位于尚未结束的轮次内：`UserPromptSubmit`、`PreToolUse`、`PostToolUse` 与 `Stop` 按构造满足该关系，而 `SessionStart` 在轮次 1 之前运行、没有 `hook/*` 记录——改为投递其注入的上下文。不变式伴生插件注册到 `ctx.invariants`，拒绝在未开启轮次外追加的 `hook/*` 事件、没有匹配 invoked 的结果、未知方言或非有限时长。
+
+### 设计理念
+
+- **把唯一差异轴收拢进 `mode`。** 两个方言只在 matcher pattern 的解读方式上不同，因此 matcher 把 mode 作为参数，而不是复制引擎。
+- **执行器拥有进程控制。** 命令通过 `dsh-shell` 执行器运行，而非自建 spawn：执行器已经提供了协议所需的已清理但可覆盖的环境、进程组取消与超时。
+- **绝不向循环抛异常。** 每种失败模式——格式错误的 JSON、无效正则、执行器拒绝——都会降级为受控的结果或不匹配，因此钩子永远不能使调用轮次崩溃。
+- **仅日志、轮次内的事件。** `hook/*` 记录是「运行了什么、决定了什么」的持久证据；它们不是 surface 事件，不变式伴生插件会拒绝未开启轮次外的记录。

It is the **CC dialect** half of the hooks subsystem: it owns the bridge's CC-shaped per-event stdin payloads, CC's env + `${CLAUDE_PLUGIN_ROOT}`/`${CLAUDE_PROJECT_DIR}` substitution, and the mapping from a hook's neutral outcome onto the harness's typed Decisions. The dialect-agnostic primitives (matcher, exit-code/stdout codec, `ctx.shell` execution, most-restrictive merge, the `hook/*` events) come from [`@deepseek-ai/dsh-hook-protocol`](../hook-protocol/README.md).
+## Summary
 
-A native cordis plugin could do everything this bridge does — more powerfully, with typed returns and no serialization boundary. **The bridge exists only as a compatibility path for the mapped CC command-hook subset**; anything bespoke should be a native plugin on the same extension points (see [the interception extension-points Agent Note](../../../.agents/notes/implemented/feature/2026-06-30-interception-extension-points.md)).
+`dsh-hooks-claude-code` runs the hooks from your existing Claude Code config — a `hooks.json` or a settings file's `hooks` key — during agent runs, so the behavior you already wrote keeps working without rewriting it. Your hooks fire at the matching moments: when a session starts, when a prompt is submitted, before and after a tool runs, when the run is about to stop, and when subagents start or end. A hook can block a prompt or tool call with a message the model sees, attach extra context to the conversation, or force the run to continue. Choose it when you have Claude Code command hooks and want them to work in the harness as-is; behavior with no Claude Code equivalent belongs in a native plugin.

+## Use this package
+
+Mount this package, point `configPath` at your hook config, and the hooks you already have start firing at the corresponding moments in agent runs. There is nothing else to set up before the first hook works.
+
+### When to choose it
+
+Use it when you own a Claude Code `hooks.json` (or a settings file whose `hooks` key holds the config) and its command hooks should gate prompts, tools, and turns. Skip it for behavior with no Claude Code equivalent: a native plugin has the full harness API, while this bridge runs only the reference tool's command-hook subset.
+
+### Smallest working setup
 
 ```yaml
-- dsh-hooks-claude-code:
+- name: '@deepseek-ai/dsh-hooks-claude-code'
+  config:
     configPath: ./.claude/hooks.json
     pluginRoot: ./.claude/plugins/my-plugin
     projectDir: .
 ```
 
-The config is parsed **once** at load. `configPath` is **process-level**: a relative path resolves against the process's launch cwd at load time, so a single config applies to the whole process — there is no per-session (`session/new.cwd`) config discovery yet (`TODO(per-session-hook-config)`). A read/parse failure is contained — including an invalid regex matcher on an event that consumes matchers, reported with its pattern and event — and the bridge logs a warning and registers nothing rather than crashing boot (a typo'd path must not take the agent down). Only shell-form `type: 'command'` hooks run; an `http`/`mcp_tool`/`prompt`/`agent` hook is parsed-and-skipped with a warning. A hook with no per-hook `timeout` runs under the protocol's reference default (`DEFAULT_HOOK_TIMEOUT_MS` from `dsh-hook-protocol`, 10 minutes — the CC default).
-
-The hooks **themselves** run in the agent's session workspace: for the agent-scoped points the bridge passes the session's `cwd` (the `session/new.cwd`) as the hook process's working directory, so a hook's `pwd`/relative-path/marker operates in the user's project tree, not the server launch dir.
-
-## Hook points → typed Decisions
-
-| CC hook | Harness point | Mapping |
+| Field | Default | Meaning |
 |---|---|---|
-| `SessionStart` | `agent/session-start` (emit) | additionalContext → `agent.inject()` into the new session (cannot block) |
-| `UserPromptSubmit` | `agent/pre-step` (waterfall) | `deny` → `PreStepDecision.reject`; additionalContext-only → delegate via `next()` then append a separately sourced message to a downstream `enter` decision (a later outer listener can still reject/rewrite) |
-| `PreToolUse` | `tools/pre-execute` (waterfall) | `deny` → `PreToolDecision.deny`; `ask` → `PreToolDecision.ask` |
-| `PostToolUse` | `tools/post-execute` (waterfall) | `deny` → `block` with feedback; additionalContext-only → delegate via `next()` then prepend a separately sourced context to the downstream decision; Code Mode defers sub-call contexts until the outer `run_code` result |
-| `Stop` | `agent/turn-stopping` (serial) | a blocking Stop hook feeds its reason through `steer()`, forcing another step |
-| `SubagentStart` | `subagent/start` (emit) | additionalContext → `agent.inject()` into a live in-process child; a remote child has no local injection target |
-| `SubagentStop` | `subagent/end` (emit) | observe-only |
+| `configPath` | required | Path to a `hooks.json` or a settings file whose `hooks` key holds the config |
+| `pluginRoot` | — | Replaces `${CLAUDE_PLUGIN_ROOT}` in command strings |
+| `projectDir` | session workspace | Replaces `${CLAUDE_PROJECT_DIR}` and sets the `CLAUDE_PROJECT_DIR` env var |
+| `defaultTimeoutMs` | `600,000` | Per-hook timeout when a hook sets none (the Claude Code default) |
+| `stderrSummaryMaxChars` | `500` | Character cap on the persisted `hook/result` stderr summary |
 
-The three emit points run detached — no extension point awaits a `SessionStart`/`SubagentStart`/`SubagentStop` hook. Each run chain is tracked, and disposing the bridge aborts still-running hook processes, then drains the continuations before the dispose resolves (`createDetachedRuns` in `dsh-hook-protocol`).
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-hooks-claude-code) is the exhaustive source for every accepted field.
 
-The matcher subject is the tool name (`PreToolUse`/`PostToolUse`), the session source (`SessionStart`), or a constant `agent_type` of `general-purpose` (`SubagentStart`/`SubagentStop` — the harness subagent seam carries no per-kind label, so the bridge reports Claude Code's own Task-tool default; a default/`*`/empty `agent_type` matcher fires, a specific-kind matcher does not); `UserPromptSubmit`/`Stop` ignore matchers. Multiple file-configured hooks on one point run **serially, in config order**, and fold most-restrictively (`deny > ask > allow`, see `dsh-hook-protocol`); serial keeps each hook's `hook/invoked`/`hook/result` pair adjacent in the log, and the fold is order-independent for the decision (see the Agent Note's "run serially, not concurrently" note).
+### What your hooks can do
 
-Every agent-scoped stdin payload carries `session_id` and string-shaped `transcript_path`. The bridge resolves the latter through `ctx.sessionPersistence.locate(session.header)` when available and otherwise sends `''`. Lookup does not create or flush the artifact, so a path can be absent before the first turn-end checkpoint or omit the current open turn.
+| Your hook | When it runs | What it can do |
+|---|---|---|
+| `SessionStart` | when a session starts | attach context the model sees in that session |
+| `UserPromptSubmit` | when the agent receives a prompt | block the prompt, or attach extra context |
+| `PreToolUse` | before a tool runs | block the tool, or ask for approval before it runs |
+| `PostToolUse` | after a tool runs | block the result with feedback, or attach extra context |
+| `Stop` | when the run is about to stop | force another step with a reason |
+| `SubagentStart` | when a subagent starts | attach context to a still-running subagent (in-process only) |
+| `SubagentStop` | when a subagent ends | observe only — cannot block or add context |
 
-## Context source
+### How hooks run and fail
 
-Injected context carries an explicit `{ kind: 'plugin', plugin: 'hooks-claude-code' }` source so the durable message is never mistaken for a user prompt.
+- Hooks run in your project directory — the agent's session workspace — so `pwd` and relative paths in your hooks refer to your project, not the server's launch directory.
+- `${CLAUDE_PLUGIN_ROOT}` and `${CLAUDE_PROJECT_DIR}` in command strings are replaced from your config, and `CLAUDE_PROJECT_DIR` is set for every hook process.
+- One config applies to the whole process: it is read once at startup, and a relative `configPath` resolves from the directory that launched the process.
+- Hooks on the same event run one after another, in config order.
+- If the config cannot be read or parsed, the bridge logs a warning and runs no hooks — the agent still starts.
+- A hook that fails to run (a bad command or a crash) is logged, and the agent continues.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the bridge and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Hook point mapping
+
+Each supported event programs against one harness extension point: `SessionStart` emits context into the new session (`agent/session-start`), `UserPromptSubmit` and `PreToolUse` are waterfalls that can reject the incoming action (`agent/pre-step`, `tools/pre-execute`), `PostToolUse` is a waterfall that can block with feedback or add context to the downstream decision (`tools/post-execute`), and `Stop` is a serial listener whose blocking result forces another step through `steer()` (`agent/turn-stopping`). The two subagent events emit into the child lifecycle (`subagent/start`, `subagent/end`): start injects context into a live in-process child, stop observes only. Context-only hooks always delegate via `next()` before folding a sourced message into the downstream decision, so a later listener can still reject or rewrite; blocking decisions map to `deny` (`ask` for `PreToolUse`). The per-event wiring lives in [`src/index.ts`](src/index.ts).
+
+### Payloads and environment
+
+The bridge builds each event's stdin payload from a base of `session_id`, string-shaped `transcript_path`, `cwd`, and `hook_event_name` plus per-event fields. `transcript_path` resolves through `ctx.sessionPersistence.locate(session.header)` when available and otherwise is `''`; lookup never creates or flushes the artifact. `CLAUDE_PROJECT_DIR` defaults per-run to the session workspace when `projectDir` is omitted, matching the directory the hook runs in; `${CLAUDE_PLUGIN_ROOT}` and `${CLAUDE_PROJECT_DIR}` substitution happens at config parse time.
+
+### Matcher subjects and serial execution
+
+The matcher subject is the tool name (`PreToolUse` / `PostToolUse`), the session source (`SessionStart`), or the constant `agent_type` `general-purpose` (`SubagentStart` / `SubagentStop` — the subagent seam carries no per-kind label); `UserPromptSubmit` and `Stop` ignore matchers. Matched hooks run serially in config order, which keeps each hook's `hook/invoked` / `hook/result` pair adjacent in the log, and the most-restrictive fold is order-independent (`deny > ask > allow`).
+
+### Detached runs and disposal
+
+The three emit points (`SessionStart`, `SubagentStart`, `SubagentStop`) run detached — no extension point awaits them. Each run chain is tracked, and disposing the bridge aborts still-running hook processes, then drains the continuations before the dispose resolves (`createDetachedRuns` in `dsh-hook-protocol`).
+
+### Design philosophy
+
+- **A compatibility adapter, not a power tool.** The bridge exists to run the explicitly supported command-hook subset of an existing Claude Code config; bespoke behavior belongs in a native plugin on the same extension points.
+- **Adding context is not a veto.** A context-only hook delegates via `next()` before folding its message into a downstream enter decision, so a later `agent/pre-step` or `tools/post-execute` listener can still reject or rewrite.
+- **Containment at every failure.** Config read/parse failures and invalid matchers register nothing; a throwing detached inject is caught and logged instead of breaking session boot or the loop.
+- **Dispose reaches quiescence.** Detached runs are tracked and drained on disposal so no hook process or late callback outlives the fiber.
+- **Serial, not concurrent.** Matched hooks run serially in config order: each `hook/invoked` / `hook/result` pair stays adjacent in the log, and the decision fold is order-independent, so the outcome matches the reference engines' concurrent launch at the cost of serialized latency.
+
+The [hook-bridges Agent Note](../../../.agents/notes/implemented/feature/2026-06-30-hook-bridges.md) records the bridge design and the deferred gaps; the [hook-protocol-lib Agent Note](../../../.agents/notes/implemented/feature/2026-06-30-hook-protocol-lib.md) records the shared-versus-per-dialect split.

Config for these events is ignored before group parsing, so an unsupported event cannot invalidate or register hooks. The comparison baseline is Claude Code's [official hook-event reference](https://code.claude.com/docs/en/hooks#hook-events).
-- **`SessionStart` is partial:** JSON `additionalContext` is consumed, but plain stdout context, `initialUserMessage`, `sessionTitle`, `watchPaths`, `reloadSkills`, and `CLAUDE_ENV_FILE` are unsupported. The hook runs detached, so context can miss the first request (`TODO(session-start-gating)`), and the payload omits current optional fields such as `model`, `agent_type`, and `session_title`.
-- **`UserPromptSubmit` is partial:** blocking and JSON `additionalContext` work, but plain stdout context, `sessionTitle`, and `suppressOriginalPrompt` are unsupported. Unless overridden, the bridge also uses its 600-second default instead of Claude Code's event-specific 30-second command timeout.
-- **`PreToolUse` is partial:** `deny` and `ask` decisions work; `allow` does not pre-approve, `defer` is unsupported, `additionalContext` is ignored, and `updatedInput` is logged + warned but not honored ([the pre-tool-input-rewrite Agent Note](../../../.agents/notes/proposed/feature/2026-06-30-pre-tool-input-rewrite.md)).
-- **`PostToolUse` is partial:** blocking feedback and JSON `additionalContext` work, but `updatedToolOutput` and `updatedMCPToolOutput` are unsupported and `tool_response` is flattened to text.
-- **`SubagentStart` and `SubagentStop` are partial:** both report a constant `agent_type` of `general-purpose` and use the child session id where Claude Code reports the parent session. Start context is best-effort and can only reach a live in-process child, while stop is observe-only and cannot block the subagent or feed it context. Start omits `transcript_path`; stop also omits `agent_transcript_path`, `last_assistant_message`, `background_tasks`, and `session_crons` and always reports `stop_hook_active: false`.
-- **`Stop` is partial:** blocking forces another model turn, but `stop_hook_active` is always `false`, `last_assistant_message`, `background_tasks`, and `session_crons` are omitted, and the consecutive-block cap is not implemented (`TODO(stop-loop-guard)`). An unconditionally blocking hook therefore force-continues every step unless it self-limits.
-- **Common payload and output fields are partial:** mapped event payloads omit `prompt_id`, `transcript_path`, `permission_mode`, and `effort` where Claude Code would provide them. `systemMessage` is logged + warned but not surfaced; `{"continue": false}` is recorded but does not halt the run; `suppressOutput`, `stopReason`, and `terminalSequence` are not applied (`TODO(hook-continue-false)`).

Matching handlers run serially and are not deduplicated, whereas Claude Code runs them in parallel and deduplicates identical handlers.

-一个 Cordis 插件，在 harness 的规范拦截点上运行用户现有 **Claude Code** hook 配置（`hooks.json` 或 settings 文件的 `hooks` key）中受支持的 command hook 子集。它是 hooks 子系统的 **CC 方言**部分，负责桥接中 CC 格式的逐事件 stdin payload、CC 的 env 和 `${CLAUDE_PLUGIN_ROOT}`／`${CLAUDE_PROJECT_DIR}` 替换，以及将 hook 的中性结果映射为 harness 的类型化 Decision。方言无关原语（matcher、退出码／stdout codec、`ctx.shell` 执行、最严格合并、`hook/*` 事件）来自 [`@deepseek-ai/dsh-hook-protocol`](../hook-protocol/README.zh.md)。
+## 概述
 
-原生 Cordis 插件可以完成此桥接的所有工作，功能更强，且具有类型化返回，没有序列化边界。**该桥接只是已映射 CC command hook 子集的兼容路径**；所有定制行为都应当使用相同扩展点上的原生插件（见 [拦截扩展点 Agent Note](../../../.agents/notes/implemented/feature/2026-06-30-interception-extension-points.zh.md)）。
+`dsh-hooks-claude-code` 在 agent（智能体）运行期间执行你现有 Claude Code 配置（`hooks.json` 或 settings 文件的 `hooks` key）中的钩子，让你已经写好的行为无需重写即可继续生效。你的钩子会在对应时刻触发：会话开始时、提示词提交时、工具运行前后、运行即将停止时，以及子 agent 启动或结束时。钩子可以带一条模型可见的消息阻塞提示词或工具调用、向对话附加额外上下文，或强制运行继续。当你持有 Claude Code command 钩子、希望它们原样在 harness 中工作时选择它；没有 Claude Code 对应物的行为应放入原生插件。

-配置只在加载时解析**一次**。`configPath` 是**进程级**配置：相对路径在加载时根据进程启动 cwd 解析，因此一份配置应用于整个进程。尚未进行每会话（`session/new.cwd`）配置发现（`TODO(per-session-hook-config)`）。读取／解析失败会被隔离处理，其中包括实际消费 matcher 的事件所带的无效 matcher 正则（会报告其 pattern 与事件）：桥接记录警告且不注册任何内容，而不是使启动崩溃（路径拼写错误不应使 agent（智能体）停止）。只运行 shell 形式 `type: 'command'` hook；`http`／`mcp_tool`／`prompt`／`agent` hook 会被解析并跳过，同时记录警告。没有每 hook `timeout` 的 hook 会使用协议参考默认值 `DEFAULT_HOOK_TIMEOUT_MS`（来自 `dsh-hook-protocol`，10 分钟，即 CC 默认值）。
-
-hook **本身**会在 agent 的会话工作区中运行：对 agent scope 点，桥接会将会话 `cwd`（`session/new.cwd`）作为 hook 进程工作目录，因此 hook 的 `pwd`／相对路径／marker 作用于用户项目树，而非服务器启动目录。
-
-## Hook 点 → 类型化 Decision
-
-| CC hook | Harness 点 | 映射 |
+| 字段 | 默认值 | 含义 |
 |---|---|---|
-| `SessionStart` | `agent/session-start`（emit） | additionalContext → `agent.inject()` 到新会话（无法阻塞） |
-| `UserPromptSubmit` | `agent/pre-step`（waterfall（瀑布式事件）） | `deny` → `PreStepDecision.reject`；仅 additionalContext → 通过 `next()` 委托，再向下游 `enter` 决策追加一条单独标记来源的消息（后续外层 listener 仍可 reject／改写） |
-| `PreToolUse` | `tools/pre-execute`（waterfall） | `deny` → `PreToolDecision.deny`；`ask` → `PreToolDecision.ask` |
-| `PostToolUse` | `tools/post-execute`（waterfall） | `deny` → 带反馈的 `block`；仅 additionalContext → 通过 `next()` 委托，再将一个单独标记源的上下文前置到下游决策；Code Mode 将子调用上下文延迟到外层 `run_code` 结果 |
-| `Stop` | `agent/turn-stopping`（serial） | 阻塞 Stop hook 通过 `steer()` 送入其原因，强制再执行一步 |
-| `SubagentStart` | `subagent/start`（emit） | additionalContext → `agent.inject()` 到仍在运行的同进程 child；远程 child 没有本地注入目标 |
-| `SubagentStop` | `subagent/end`（emit） | 只观测 |
+| `configPath` | 必填 | `hooks.json` 或 `hooks` key 存放配置的 settings 文件路径 |
+| `pluginRoot` | — | 替换命令字符串中的 `${CLAUDE_PLUGIN_ROOT}` |
+| `projectDir` | 会话工作区 | 替换 `${CLAUDE_PROJECT_DIR}` 并设置 `CLAUDE_PROJECT_DIR` 环境变量 |
+| `defaultTimeoutMs` | `600,000` | hook 未设置时的每 hook 超时（即 Claude Code 默认值） |
+| `stderrSummaryMaxChars` | `500` | 持久化 `hook/result` stderr 摘要的字符上限 |
 
-三个 emit 点都以分离方式运行：没有扩展点会等待 `SessionStart`／`SubagentStart`／`SubagentStop` hook。每条运行链都会被跟踪；对桥接执行 dispose（资源释放）时，会中止仍在运行的 hook 进程，并在 dispose 完成前排空 continuation（`createDetachedRuns`，位于 `dsh-hook-protocol`）。
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-hooks-claude-code)是每个受支持字段的穷尽式真源。
 
-matcher subject 是工具名称（`PreToolUse`／`PostToolUse`）、会话源（`SessionStart`），或常量 `agent_type`，其值为 `general-purpose`（`SubagentStart`／`SubagentStop`）。harness subagent seam 不携带每 kind label，因此桥接报告 Claude Code 自身 Task 工具默认值；默认／`*`／空 `agent_type` matcher 会触发，特定 kind matcher 不会触发。`UserPromptSubmit`／`Stop` 忽略 matcher。一个点上文件配置的多个 hook 会**按配置顺序串行运行**，并按最严格方式折叠（`deny > ask > allow`，见 `dsh-hook-protocol`）。串行使每个 hook 的 `hook/invoked`／`hook/result` 对在日志中相邻，权限决策的折叠结果与顺序无关（见 Agent Note 的「run serially, not concurrently」说明）。
+### 你的钩子能做什么
 
-每个 agent scope stdin payload 都携带 `session_id` 与字符串形式的 `transcript_path`。可用时，桥接通过 `ctx.sessionPersistence.locate(session.header)` 解析后者，否则发送 `''`。查找不会创建或 flush 产物，因此第一个轮次结束检查点之前路径可能不存在，也可能省略当前开启轮次。
+| 你的钩子 | 运行时机 | 能做什么 |
+|---|---|---|
+| `SessionStart` | 会话开始时 | 附加该会话中模型可见的上下文 |
+| `UserPromptSubmit` | agent 收到提示词时 | 阻塞提示词，或附加上下文 |
+| `PreToolUse` | 工具运行前 | 阻塞工具，或在运行前请求批准 |
+| `PostToolUse` | 工具运行后 | 带反馈阻塞结果，或附加上下文 |
+| `Stop` | 运行即将停止时 | 带原因强制再执行一步 |
+| `SubagentStart` | 子 agent 启动时 | 向仍在运行的子 agent 附加上下文（仅限同进程） |
+| `SubagentStop` | 子 agent 结束时 | 只观测——不能阻塞或添加上下文 |
 
-## 上下文源
+### 钩子如何运行与失败
 
-注入上下文携带显式 `{ kind: 'plugin', plugin: 'hooks-claude-code' }` 来源，因此持久消息绝不会被误认为用户提示词。
+- 钩子在你的项目目录（agent 的会话工作区）中运行，因此钩子里的 `pwd` 与相对路径指向你的项目，而非服务器启动目录。
+- 命令字符串中的 `${CLAUDE_PLUGIN_ROOT}` 与 `${CLAUDE_PROJECT_DIR}` 会按你的配置替换，且每个钩子进程都会设置 `CLAUDE_PROJECT_DIR`。
+- 一份配置应用于整个进程：启动时只读取一次，相对 `configPath` 从启动进程的目录解析。
+- 同一事件上的钩子按配置顺序逐个运行。
+- 如果配置无法读取或解析，桥接会记录警告且不运行任何钩子——agent 仍会启动。
+- 运行失败的钩子（命令错误或崩溃）会被记录，agent 继续运行。

+## 理解实现
+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释桥接背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### Hook 点映射
+
+每个受支持事件都面向一个 harness 扩展点：`SessionStart` 向新会话发射上下文（`agent/session-start`），`UserPromptSubmit` 与 `PreToolUse` 是能拒绝传入动作的 waterfall（瀑布式事件）（`agent/pre-step`、`tools/pre-execute`），`PostToolUse` 是能带反馈阻塞或向下游决策添加上下文的 waterfall（`tools/post-execute`），`Stop` 是串行监听器，其阻塞结果通过 `steer()` 强制再执行一步（`agent/turn-stopping`）。两个 subagent 事件面向 child 生命周期发射（`subagent/start`、`subagent/end`）：start 向仍在运行的同进程 child 注入上下文，stop 只观测。仅提供上下文的 hook 总是先通过 `next()` 委托，再把带来源的消息折叠进下游决策，因此后续监听器仍可拒绝或改写；阻塞决策映射为 `deny`（`PreToolUse` 为 `ask`）。逐事件接线位于 [`src/index.ts`](src/index.ts)。
+
+### 载荷与环境
+
+桥接从 `session_id`、字符串形态的 `transcript_path`、`cwd` 与 `hook_event_name` 的基础字段加逐事件字段构建每个事件的 stdin payload。可用时 `transcript_path` 通过 `ctx.sessionPersistence.locate(session.header)` 解析，否则为 `''`；查找从不创建或 flush 产物。省略 `projectDir` 时，`CLAUDE_PROJECT_DIR` 按次默认到会话工作区，与钩子运行的目录一致；`${CLAUDE_PLUGIN_ROOT}` 与 `${CLAUDE_PROJECT_DIR}` 替换在配置解析时进行。
+
+### Matcher subject 与串行执行
+
+matcher subject 是工具名称（`PreToolUse`／`PostToolUse`）、会话源（`SessionStart`），或常量 `agent_type` `general-purpose`（`SubagentStart`／`SubagentStop`——subagent seam 不携带每 kind 标签）；`UserPromptSubmit` 与 `Stop` 忽略 matcher。匹配 hook 按配置顺序串行运行，这使每个 hook 的 `hook/invoked`／`hook/result` 对在日志中相邻，且最严格折叠与顺序无关（`deny > ask > allow`）。
+
+### 脱离运行与释放
+
+三个 emit 点（`SessionStart`、`SubagentStart`、`SubagentStop`）以脱离方式运行——没有扩展点等待它们。每条运行链都会被跟踪，对桥接执行 dispose（资源释放）时会中止仍在运行的 hook 进程，并在 dispose 完成前排空 continuation（`createDetachedRuns`，位于 `dsh-hook-protocol`）。
+
+### 设计理念
+
+- **兼容适配器，而非强力工具。** 桥接的存在意义是运行现有 Claude Code 配置中显式受支持的 command hook 子集；定制行为应放在同一批扩展点上的原生插件中。
+- **添加上下文不是否决。** 仅提供上下文的 hook 会先通过 `next()` 委托，再把其消息折叠进下游 enter 决策，因此后续 `agent/pre-step` 或 `tools/post-execute` 监听器仍可拒绝或改写。
+- **每个失败点都受控。** 配置读取／解析失败与无效 matcher 不注册任何内容；抛异常的脱离注入会被捕获并记录，而不是破坏会话启动或循环。
+- **dispose 必须达到完全停稳。** 脱离运行会被跟踪并在释放时排空，因此不会有 hook 进程或迟到回调超出 fiber 存活。
+- **串行而非并发。** 匹配 hook 按配置顺序串行运行：每个 `hook/invoked`／`hook/result` 对在日志中保持相邻，且决策折叠与顺序无关，因此结果与参考引擎的并发启动一致，代价是串行化的延迟。

 # @deepseek-ai/dsh-hooks-codex
 
 English | [中文](README.zh.md)
 
-A cordis plugin that runs the supported subset of a user's existing **Codex** hook config on the harness's canonical interception points. The **Codex dialect** half of the hooks subsystem. The dialect-agnostic primitives come from [`@deepseek-ai/dsh-hook-protocol`](../hook-protocol/README.md); this bridge owns the Codex-shaped payloads, matcher mode, and decision mapping.
+## Summary
 
-This bridge implements a deliberate subset of Codex's current hook protocol:
+`dsh-hooks-codex` runs the hooks from your existing Codex config — a `hooks.json` — during agent runs, so the behavior you already wrote keeps working without rewriting it. Five of Codex's hook points fire at the matching moments: when a session starts, when a prompt is submitted, before and after a tool runs, and when the run is about to stop. A hook can block a prompt or tool call with a message the model sees, attach extra context to the conversation, or force the run to continue. Choose it when you have Codex command hooks and want them to work in the harness as-is; behavior with no Codex equivalent belongs in a native plugin.
 
-- **Five of ten hook points:** `PreToolUse`, `PostToolUse`, `SessionStart`, `UserPromptSubmit`, and `Stop`.
-- **Regex-only matchers** (no literal fast path; the matcher is always an unanchored regex).
-- **snake_case stdin payloads** with `turn_id`/`model` extras, written **without** a trailing newline.
-- **No Codex plugin env injection and no config-time placeholder substitution** (the command still receives the executor's environment and runs through its shell).
-- **No pre-tool approval or rewrite path** — a hook can block, but the bridge does not pre-approve or replace tool input.
+## Table of Contents
 
-A native cordis plugin could do everything this bridge does, more powerfully; the bridge exists only as a compatibility path for the mapped Codex subset (see [the interception extension-points Agent Note](../../../.agents/notes/implemented/feature/2026-06-30-interception-extension-points.md)).

-## Config
+-----
 
-```ts
-import type { Config } from '@deepseek-ai/dsh-hooks-codex'
-const config: Config = {
-  configPath: '/path/to/.codex/hooks.json', // required
-  model: 'deepseek-v4',                      // optional: stamped on every payload (Codex includes `model`)
-  defaultTimeoutMs: 600_000,                 // optional: per-hook timeout when a hook sets none
-  stderrSummaryMaxChars: 500,                // optional: char cap on the hook/result event's persisted stderr summary
-}
-```
+<a id="use-this-package"></a>
+## Use this package
 
-In a `cordis.yml`:
+Mount this package, point `configPath` at your `hooks.json`, and the hooks you already have start firing at the corresponding moments in agent runs. There is nothing else to set up before the first hook works.
+
+### When to choose it
+
+Use it when you own a Codex `hooks.json` and its command hooks should gate prompts, tools, and turns. Skip it for behavior with no Codex equivalent: a native plugin has the full harness API, while this bridge runs only the reference tool's command-hook subset.
+
+### Smallest working setup
 
 ```yaml
-- dsh-hooks-codex:
+- name: '@deepseek-ai/dsh-hooks-codex'
+  config:
     configPath: ./.codex/hooks.json
     model: deepseek-v4
 ```
 
-The config is parsed **once** at load. `configPath` is **process-level** — a relative path resolves against the process launch cwd at load time, not per-session (`TODO(per-session-hook-config)`). A read/parse failure is contained (logs + registers nothing); an invalid regex matcher on an event that consumes matchers is one such failure and reports its pattern and event. Only sync `type: 'command'` hooks run — a non-command or `async: true` hook is parsed-and-skipped with a warning. A hook accepts `timeout` or the `timeoutSec` alias; one that sets neither runs under the protocol's reference default (`DEFAULT_HOOK_TIMEOUT_MS` from `dsh-hook-protocol`, 10 minutes). Events outside the five bridge-supported points are dropped at parse.
-
-The hooks themselves run in the agent's session workspace: for the agent-scoped points the bridge passes the session's `cwd` as the hook process's working directory, so a hook operates in the user's project tree, not the server launch dir.
-
-## Hook points → typed Decisions
-
-| Codex hook | Harness point | Mapping |
+| Field | Default | Meaning |
 |---|---|---|
-| `SessionStart` | `agent/session-start` (emit) | a plain-stdout hook's output → additionalContext → `agent.inject()` |
-| `UserPromptSubmit` | `agent/pre-step` (waterfall) | `block` (exit 2) → `PreStepDecision.reject`; additionalContext-only → delegate via `next()` then append a separately sourced message to a downstream `enter` decision |
-| `PreToolUse` | `tools/pre-execute` (waterfall) | `block` → `PreToolDecision.deny` (no `allow`/`ask`) |
-| `PostToolUse` | `tools/post-execute` (waterfall) | `block` → `block` with feedback; additionalContext-only → delegate via `next()` then prepend a separately sourced context to the downstream decision; Code Mode defers sub-call contexts until the outer `run_code` result |
-| `Stop` | `agent/turn-stopping` (serial) | a blocking Stop hook feeds its reason through `steer()`, forcing another step |
+| `configPath` | required | Path to a Codex `hooks.json` |
+| `model` | `''` | Model name stamped on every payload (Codex includes `model` on each event) |
+| `defaultTimeoutMs` | `600,000` | Per-hook timeout when a hook sets none (the Codex default) |
+| `stderrSummaryMaxChars` | `500` | Character cap on the persisted `hook/result` stderr summary |
 
-A tool call's payload carries the real `tool_name` (the same value the matcher tests) and Codex's `tool_input: { command }` shape (the `command` arg when present, else `''`). The matcher subject is the tool name (`PreToolUse`/`PostToolUse`) or the session source (`SessionStart`); `UserPromptSubmit`/`Stop` ignore matchers.
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-hooks-codex) is the exhaustive source for every accepted field.
 
-Every agent-scoped stdin payload carries `session_id` and `transcript_path`. The bridge resolves the latter through `ctx.sessionPersistence.locate(session.header)` when available and otherwise sends `null`, preserving the Codex `string | null` shape. Lookup does not create or flush the artifact, so a path can be absent before the first turn-end checkpoint or omit the current open turn.
+### What your hooks can do
 
-`SessionStart` — the one emit point — runs detached; each run chain is tracked, and disposing the bridge aborts a still-running hook process, then drains the continuation before the dispose resolves (`createDetachedRuns` in `dsh-hook-protocol`).
+| Your hook | When it runs | What it can do |
+|---|---|---|
+| `SessionStart` | when a session starts | attach context the model sees in that session |
+| `UserPromptSubmit` | when the agent receives a prompt | block the prompt, or attach extra context |
+| `PreToolUse` | before a tool runs | block the tool |
+| `PostToolUse` | after a tool runs | block the result with feedback, or attach extra context |
+| `Stop` | when the run is about to stop | force another step with a reason |
 
-## Context source
+### How hooks run and fail
 
-Injected context carries an explicit `{ kind: 'plugin', plugin: 'hooks-codex' }` source so the durable message is never mistaken for a user prompt.
+- Hooks run in your project directory — the agent's session workspace — so `pwd` and relative paths in your hooks refer to your project, not the server's launch directory.
+- One config applies to the whole process: it is read once at startup, and a relative `configPath` resolves from the directory that launched the process.
+- Only synchronous command hooks run; an `async: true` or non-command hook is skipped with a warning.
+- Hooks on the same event run one after another, in config order.
+- If the config cannot be read or parsed, the bridge logs a warning and runs no hooks — the agent still starts.
+- A hook that fails to run (a bad command or a crash) is logged, and the agent continues.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the bridge and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Hook point mapping
+
+Each supported event programs against one harness extension point: `SessionStart` emits context into the new session (`agent/session-start`), `UserPromptSubmit` and `PreToolUse` are waterfalls that can reject the incoming action (`agent/pre-step`, `tools/pre-execute`), `PostToolUse` is a waterfall that can block with feedback or add context to the downstream decision (`tools/post-execute`), and `Stop` is a serial listener whose blocking result forces another step through `steer()` (`agent/turn-stopping`). Context-only hooks always delegate via `next()` before folding a sourced message into the downstream decision, so a later listener can still reject or rewrite; blocking decisions map to `deny` (`PreToolUse` has no `allow` or `ask`). The per-event wiring lives in [`src/index.ts`](src/index.ts).
+
+### Payloads and environment
+
+Payloads are Codex-shaped: snake_case with `turn_id` on turn-scoped events, `model` and `permission_mode: "default"` on every event, and stdin written without a trailing newline. A tool call's payload carries the real `tool_name` and the `tool_input: { command }` shape (the `command` argument when present, else `''`), so non-shell tool arguments are not faithfully exposed. The base payload carries `session_id` and `transcript_path`; the latter resolves through `ctx.sessionPersistence.locate(session.header)` when available and otherwise is `null`, preserving the Codex `string | null` shape — lookup never creates or flushes the artifact. Codex performs no command substitution and injects no plugin environment.
+
+### Matcher subjects and serial execution
+
+The matcher subject is the tool name (`PreToolUse` / `PostToolUse`) or the session source (`SessionStart`); `UserPromptSubmit` and `Stop` ignore matchers. Codex matchers are always unanchored regexes. Matched hooks run serially in config order, which keeps each hook's `hook/invoked` / `hook/result` pair adjacent in the log, and the most-restrictive fold is order-independent (`deny > ask > allow`).
+
+### Detached runs and disposal
+
+`SessionStart` is the one emit point and runs detached — no extension point awaits it. Each run chain is tracked, and disposing the bridge aborts a still-running hook process, then drains the continuation before the dispose resolves (`createDetachedRuns` in `dsh-hook-protocol`).
+
+### Design philosophy
+
+- **A compatibility adapter, not a power tool.** The bridge exists to run the explicitly supported subset of an existing Codex config; bespoke behavior belongs in a native plugin on the same extension points.
+- **Adding context is not a veto.** A context-only hook delegates via `next()` before folding its message into a downstream enter decision, so a later `agent/pre-step` or `tools/post-execute` listener can still reject or rewrite.
+- **Containment at every failure.** Config read/parse failures and invalid matchers register nothing; a throwing detached inject is caught and logged instead of breaking session boot or the loop.
+- **Dispose reaches quiescence.** Detached runs are tracked and drained on disposal so no hook process or late callback outlives the fiber.
+- **Dialect-shaped, not maximal.** Payloads stay snake_case with `turn_id` / `model`, stdin carries no trailing newline, and the bridge implements no pre-tool approval or rewrite path — the protocol's shape is preserved even where the harness could do more.
+
+The [hook-bridges Agent Note](../../../.agents/notes/implemented/feature/2026-06-30-hook-bridges.md) records the bridge design and the deferred gaps; the [hook-protocol-lib Agent Note](../../../.agents/notes/implemented/feature/2026-06-30-hook-protocol-lib.md) records the shared-versus-per-dialect split.

Config for these events is silently dropped during parsing. The comparison baseline is Codex's [official hook reference](https://learn.chatgpt.com/docs/hooks).
-- **`SessionStart` is partial:** plain stdout and JSON `additionalContext` work, but the hook runs detached, so context can miss the first request (`TODO(session-start-gating)`).
-- **`UserPromptSubmit` is partial:** blocking plus plain-stdout or JSON context work, but the common `systemMessage` and `{"continue": false}` controls are not enforced.
-- **`PreToolUse` is partial:** blocking works, but `additionalContext`, `permissionDecision: "allow"`, and `updatedInput` are ignored. Every tool is represented as `tool_input: { command }`, so non-shell tool arguments are not faithfully exposed to the hook.
-- **`PostToolUse` is partial:** blocking feedback and JSON `additionalContext` work, but `{"continue": false}` is not enforced, non-shell tool arguments are reduced to `{ command }`, and structured tool output is flattened to text in `tool_response`.
-- **`Stop` is partial:** blocking forces another model turn, but `stop_hook_active` is always `false`, `last_assistant_message` is always `null`, and `{"continue": false}` is not enforced. An unconditionally blocking hook therefore force-continues every step unless it self-limits (`TODO(stop-loop-guard)`).
-- **Common payload and output fields are partial:** every mapped event reports the statically configured `model` and `permission_mode: "default"` instead of current Codex runtime values. `systemMessage` is logged + warned but not surfaced, and `{"continue": false}` is recorded but does not apply Codex's event-specific stop behavior (`TODO(hook-continue-false)`).
-- **Config loading and execution are partial:** one process-level `configPath` is parsed at load; Codex's active user, project, session, system/managed, and plugin layers, trust controls, and inline `config.toml` hook form are not implemented (`TODO(per-session-hook-config)`).

 # @deepseek-ai/dsh-hooks-codex
 
 [English](README.md) | 中文
 
-一个 Cordis 插件，在 harness 的规范拦截点上运行用户现有 **Codex** hook 配置的受支持子集。它是 hooks 子系统中采用 **Codex 方言** 的一侧。方言无关原语来自 [`@deepseek-ai/dsh-hook-protocol`](../hook-protocol/README.zh.md)；该桥接负责处理 Codex 形状的 payload、matcher 模式和决策映射。
+## 概述
 
-该桥接实现 Codex 当前 hook 协议的一个有意选取的子集：
+`dsh-hooks-codex` 在 agent（智能体）运行期间执行你现有 Codex 配置（`hooks.json`）中的钩子，让你已经写好的行为无需重写即可继续生效。Codex 的 5 个 hook 点会在对应时刻触发：会话开始时、提示词提交时、工具运行前后，以及运行即将停止时。钩子可以带一条模型可见的消息阻塞提示词或工具调用、向对话附加额外上下文，或强制运行继续。当你持有 Codex command 钩子、希望它们原样在 harness 中工作时选择它；没有 Codex 对应物的行为应放入原生插件。
 
-- **10 个 hook 点中的 5 个：** `PreToolUse`、`PostToolUse`、`SessionStart`、`UserPromptSubmit` 和 `Stop`。
-- **仅使用正则的 matcher**（没有字面量快速路径；matcher 始终是未锚定正则）。
-- **snake_case stdin payload**，携带 `turn_id`／`model` 额外字段，写入时**不带**尾随换行符。
-- **没有 Codex 插件 env 注入，也没有配置时 placeholder 替换**（命令仍会接收执行器环境，并通过其 shell 运行）。
-- **没有工具前审批或改写路径**：hook 可以阻塞，但桥接不会预审批或替换工具输入。
+## 目录
 
-原生 Cordis 插件可以完成此桥接的所有工作，并且功能更强；该桥接只是已映射 Codex 子集的兼容路径（见 [拦截扩展点 Agent Note](../../../.agents/notes/implemented/feature/2026-06-30-interception-extension-points.zh.md)）。

-## 配置
+-----
 
-```ts
-import type { Config } from '@deepseek-ai/dsh-hooks-codex'
-const config: Config = {
-  configPath: '/path/to/.codex/hooks.json', // required
-  model: 'deepseek-v4',                      // optional: stamped on every payload (Codex includes `model`)
-  defaultTimeoutMs: 600_000,                 // optional: per-hook timeout when a hook sets none
-  stderrSummaryMaxChars: 500,                // optional: char cap on the hook/result event's persisted stderr summary
-}
-```
+<a id="use-this-package"></a>
+## 使用本包
 
-在 `cordis.yml` 中：
+挂载本包并把 `configPath` 指向你的 `hooks.json`，你已有的钩子就会在 agent 运行中的对应时刻开始触发。在第一个钩子生效之前无需其他设置。
+
+### 何时选择
+
+当你持有 Codex `hooks.json`、且其中的 command 钩子需要把关提示词、工具与轮次时，使用它。没有 Codex 对应物的行为请跳过它：原生插件拥有完整的 harness API，而本桥接只运行参考工具的 command hook 子集。
+
+### 最小配置
 
 ```yaml
-- dsh-hooks-codex:
+- name: '@deepseek-ai/dsh-hooks-codex'
+  config:
     configPath: ./.codex/hooks.json
     model: deepseek-v4
 ```
 
-配置只在加载时解析**一次**。`configPath` 是**进程级**配置：相对路径在加载时根据进程启动 cwd 解析，而非每会话解析（`TODO(per-session-hook-config)`）。读取／解析失败会被隔离处理（记录 + 不注册任何内容）；实际消费 matcher 的事件所带的无效 matcher 正则属于此类失败，并报告其 pattern 与事件。只运行同步 `type: 'command'` hook；非 command 或 `async: true` hook 会被解析并跳过，同时记录警告。hook 接受 `timeout` 或 `timeoutSec` alias；两者都未设置时，使用协议参考默认值 `DEFAULT_HOOK_TIMEOUT_MS`（来自 `dsh-hook-protocol`，10 分钟）。五个桥接支持点之外的事件会在解析时丢弃。
-
-hook 本身会在 agent（智能体）的会话工作区中运行：对 agent scope 点，桥接会将会话 `cwd` 作为 hook 进程工作目录，因此 hook 作用于用户项目树，而非服务器启动目录。
-
-## Hook 点 → 类型化 Decision
-
-| Codex hook | Harness 点 | 映射 |
+| 字段 | 默认值 | 含义 |
 |---|---|---|
-| `SessionStart` | `agent/session-start`（emit） | 纯 stdout hook 的输出 → additionalContext → `agent.inject()` |
-| `UserPromptSubmit` | `agent/pre-step`（waterfall，瀑布式事件） | `block`（退出码 2）→ `PreStepDecision.reject`；仅 additionalContext → 通过 `next()` 委托，再向下游 `enter` 决策追加一条单独标记来源的消息 |
-| `PreToolUse` | `tools/pre-execute`（waterfall） | `block` → `PreToolDecision.deny`（没有 `allow`／`ask`） |
-| `PostToolUse` | `tools/post-execute`（waterfall） | `block` → 带反馈的 `block`；仅 additionalContext → 通过 `next()` 委托，再将一个单独标记源的上下文前置到下游决策；Code Mode 将子调用上下文延迟到外层 `run_code` 结果 |
-| `Stop` | `agent/turn-stopping`（serial） | 阻塞 Stop hook 通过 `steer()` 送入其原因，强制再执行一步 |
+| `configPath` | 必填 | Codex `hooks.json` 的路径 |
+| `model` | `''` | 盖在每个 payload 上的模型名称（Codex 在每个事件中都包含 `model`） |
+| `defaultTimeoutMs` | `600,000` | hook 未设置时的每 hook 超时（即 Codex 默认值） |
+| `stderrSummaryMaxChars` | `500` | 持久化 `hook/result` stderr 摘要的字符上限 |
 
-工具调用的 payload 携带真实 `tool_name`（matcher 测试的相同值）与 Codex `tool_input: { command }` 形状（存在 `command` arg 时使用该值，否则使用 `''`）。matcher subject 是工具名称（`PreToolUse`／`PostToolUse`）或会话源（`SessionStart`）；`UserPromptSubmit`／`Stop` 忽略 matcher。
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-hooks-codex)是每个受支持字段的穷尽式真源。
 
-每个 agent scope stdin payload 都携带 `session_id` 和 `transcript_path`。可用时，桥接通过 `ctx.sessionPersistence.locate(session.header)` 解析后者，否则发送 `null`，保留 Codex `string | null` 形状。查找不会创建或 flush 产物，因此在第一个轮次结束检查点之前，路径可能尚不存在，或其指向的 transcript（文本记录）可能尚未包含当前未结束的轮次。
+### 你的钩子能做什么
 
-`SessionStart` 是唯一的 emit 点，它会脱离运行。每条运行链都会被跟踪；对桥接执行 dispose（资源释放）会中止仍在运行的 hook 进程，再排空 continuation，之后 dispose 才会完成（`createDetachedRuns`，位于 `dsh-hook-protocol`）。
+| 你的钩子 | 运行时机 | 能做什么 |
+|---|---|---|
+| `SessionStart` | 会话开始时 | 附加该会话中模型可见的上下文 |
+| `UserPromptSubmit` | agent 收到提示词时 | 阻塞提示词，或附加上下文 |
+| `PreToolUse` | 工具运行前 | 阻塞工具 |
+| `PostToolUse` | 工具运行后 | 带反馈阻塞结果，或附加上下文 |
+| `Stop` | 运行即将停止时 | 带原因强制再执行一步 |
 
-## 上下文源
+### 钩子如何运行与失败
 
-注入上下文携带显式 `{ kind: 'plugin', plugin: 'hooks-codex' }` 来源，因此持久消息绝不会被误认为用户提示词。
+- 钩子在你的项目目录（agent 的会话工作区）中运行，因此钩子里的 `pwd` 与相对路径指向你的项目，而非服务器启动目录。
+- 一份配置应用于整个进程：启动时只读取一次，相对 `configPath` 从启动进程的目录解析。
+- 只运行同步 command 钩子；`async: true` 或非 command 钩子会被跳过并给出警告。
+- 同一事件上的钩子按配置顺序逐个运行。
+- 如果配置无法读取或解析，桥接会记录警告且不运行任何钩子——agent 仍会启动。
+- 运行失败的钩子（命令错误或崩溃）会被记录，agent 继续运行。

+## 理解实现
+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释桥接背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### Hook 点映射
+
+每个受支持事件都面向一个 harness 扩展点：`SessionStart` 向新会话发射上下文（`agent/session-start`），`UserPromptSubmit` 与 `PreToolUse` 是能拒绝传入动作的 waterfall（瀑布式事件）（`agent/pre-step`、`tools/pre-execute`），`PostToolUse` 是能带反馈阻塞或向下游决策添加上下文的 waterfall（`tools/post-execute`），`Stop` 是串行监听器，其阻塞结果通过 `steer()` 强制再执行一步（`agent/turn-stopping`）。仅提供上下文的 hook 总是先通过 `next()` 委托，再把带来源的消息折叠进下游决策，因此后续监听器仍可拒绝或改写；阻塞决策映射为 `deny`（`PreToolUse` 没有 `allow` 或 `ask`）。逐事件接线位于 [`src/index.ts`](src/index.ts)。
+
+### 载荷与环境
+
+payload 采用 Codex 形状：snake_case，轮次事件带 `turn_id`，每个事件都带 `model` 与 `permission_mode: "default"`，stdin 写入时不带尾随换行符。工具调用的 payload 携带真实 `tool_name` 与 `tool_input: { command }` 形状（存在 `command` 参数时使用该值，否则使用 `''`），因此非 shell 工具参数不会被如实公开。基础 payload 携带 `session_id` 与 `transcript_path`；可用时后者通过 `ctx.sessionPersistence.locate(session.header)` 解析，否则为 `null`，保留 Codex `string | null` 形状——查找从不创建或 flush 产物。Codex 不进行命令替换，也不注入插件环境。
+
+### Matcher subject 与串行执行
+
+matcher subject 是工具名称（`PreToolUse`／`PostToolUse`）或会话源（`SessionStart`）；`UserPromptSubmit` 与 `Stop` 忽略 matcher。Codex matcher 始终是未锚定正则。匹配 hook 按配置顺序串行运行，这使每个 hook 的 `hook/invoked`／`hook/result` 对在日志中相邻，且最严格折叠与顺序无关（`deny > ask > allow`）。
+
+### 脱离运行与释放
+
+`SessionStart` 是唯一的 emit 点，它脱离运行——没有扩展点等待它。每条运行链都会被跟踪，对桥接执行 dispose（资源释放）时会中止仍在运行的 hook 进程，并在 dispose 完成前排空 continuation（`createDetachedRuns`，位于 `dsh-hook-protocol`）。
+
+### 设计理念
+
+- **兼容适配器，而非强力工具。** 桥接的存在意义是运行现有 Codex 配置中显式受支持的子集；定制行为应放在同一批扩展点上的原生插件中。
+- **添加上下文不是否决。** 仅提供上下文的 hook 会先通过 `next()` 委托，再把其消息折叠进下游 enter 决策，因此后续 `agent/pre-step` 或 `tools/post-execute` 监听器仍可拒绝或改写。
+- **每个失败点都受控。** 配置读取／解析失败与无效 matcher 不注册任何内容；抛异常的脱离注入会被捕获并记录，而不是破坏会话启动或循环。
+- **dispose 必须达到完全停稳。** 脱离运行会被跟踪并在释放时排空，因此不会有 hook 进程或迟到回调超出 fiber 存活。
+- **保持方言形状，而非最大化。** payload 保持 snake_case 并带 `turn_id`／`model`，stdin 不带尾随换行符，桥接也不实现工具前审批或改写路径——即使 harness 本可以做得更多，也保留协议的形状。

+## Summary
+
+The `host/` group is the web GUI host half: the API gateway every client shape shares, the plain HTTP server it rides on, the SPA dist server that serves the built Web shell, the workspace-directory picking seam with its native, browse, and adaptive composition packages, and the read-only plugin inventory projection. All eight packages are product packages; the browser half that consumes the gateway lives in [`client/`](../client/README.md), and the composed application is [`apps/cli`](../../apps/cli/README.md) booting the [`dsh-base` bundle](../bundle/base/cordis.patch.yml) that serves the web app under `apps/web/`. The gateway contract is transport-independent, and the picker backends replace one another behind the shared seam.

 # @deepseek-ai/dsh-host-apiproxy
 
 English | [中文](README.zh.md)
 
-The API gateway shared by every client consists of the TypeScript API contract (`src/api/`, zero Node dependencies, importable from the browser), the fetch carrier pair (`src/fetch/`: `toFetchHandler` on the host side, `AbstractApiClient` plus platform subclasses on the client side), and the host-side implementation (`src/api-proxy.ts`: `createApiProxy` plus the default-exported `ApiProxyService` gateway plugin — config `{nativeOpen?, sessionExportCompressionLevel?, coldBlankProbeMaxBytes?}`, provides `ctx.apiProxy`). This package registers no routes; carriers such as HTTP wrap `ctx.apiProxy` themselves. The shipped Web composition lives in [`packages/bundle/web-app/cordis.patch.yml`](../../bundle/web-app/cordis.patch.yml), while its default Agent model selection belongs to [`@deepseek-ai/dsh-agent-default-model`](../../core/agent-default-model/README.md) in the base bundle.
+## Summary
 
-## The shared Agent default (`agent-default-model` Settings section)
+Every client of the web GUI host calls one typed API through `dsh-host-apiproxy` — sessions and history, subagents, workspaces, directory picking, model selection, agent presets, skills, goals, settings, credentials, LLM catalogs, events, and session export — moved over HTTP or in-process by fetch carriers. The contract layer has zero Node dependencies and imports from the browser, so one typed API serves the Web server, Electron, and any future client shape. The shipped Web composition assembles the gateway in [`dsh-web-app`](../../bundle/web-app/README.md). Choosing a carrier, calling the domain APIs, and configuring the gateway come first; the wire protocol internals live in a collapsible developer section below.
 
-`ApiProxyService` consumes `ctx.agentDefaultModel`; it does not own a provider/model config or settings section. The shared service registers `{provider, model, reasoningEffort?}` under `agent-default-model`: the base bundle's composition entry is the lower layer and `settings.yaml` layers the user's choice over it.
+## Table of Contents
 
-A session resolves its model selection from three tiers on every access: a selection made in this process, otherwise the session's latest logged `request/header`, otherwise this default. A session that has run a turn derives its selection from its log, while a blank session observes a default saved after it was created. A logged reasoning effort marked as an adapter default remains absent from the restored selection, so the next model resolution does not promote that default into an explicit choice or record a false header change.

+- [Understand the implementation](#understand-the-implementation)
+- [Further Exploration](#further-exploration)
+- [Model Experience](#model-experience)
+- [Known Limitations and Deferred Work](#known-limitations-and-deferred-work)
+- [Dev Note](#dev-note)
 
-`session.selectModel` saves an accepted switch as the deployment default; there is no separate gesture. It stores the resolved `ModelSelection`, including an adapter-materialized default effort. The complete-section write clears a stored effort when the selected model has none. A storage failure is logged without undoing the session selection. A deployment with no settings provider keeps the composition entry and the switch remains session-local.
+-----
 
-The section's `reasoningEffort` has no counterpart in the agent-default-model plugin config, deliberately: the seam merges the user layer over the composition entry per field, so an absent key cannot override a present one and a composition-set effort would survive every later switch to a model without one. A deployment default for effort belongs on the adapter profile, which resolves per model.
+<a id="use-this-package"></a>
+## Use this package
 
-The stored selection is independent of catalog membership. A default naming an unavailable provider still reaches `session.models` as the session's `current`, allowing the selector to request a replacement instead of silently choosing another model. Conversely, an adapter may serve a model that its catalog does not advertise.
+Compose the gateway when a client of the GUI host needs the session, workspace, and configuration APIs: load `ApiProxyService`, wrap `ctx.apiProxy` in a carrier, and call the typed domain methods.
 
-## Contract layer (`/api`)
+### Choosing a carrier
 
-Wire messages form a four-quadrant discriminated union — who initiates × request/response — decoupled from the physical channel: `ClientRequest` (POST `/api/<method>` body), `ServerResponse` (that POST's response body), `ServerRequest` (SSE frame), `ClientResponse` (POST `/api/respond` body). Responses always echo the matching request's `rpcId` and never mint a new one. Method parameter/return structures live only in the domain interface signatures (`SessionsApi`, `HostApi`, `EventsApi`); `RpcMethodMap` registers the methods and every other position derives via `RequestPayload<K>`/`ResponseValue<K>`. Zod schemas anchor `satisfies z.ZodType<Wire<T>>` and parse at two levels: envelope first, business payload second, dispatched per method. Business errors ride `RpcResult`'s error branch (`RpcErrorDetailsMap` closes the code set); HTTP status expresses only the carrier. Every `/api` POST must declare the `application/json` media type — anything else is refused with 415 before dispatch, so cross-site "simple" requests (which browsers send without a CORS preflight) can never execute a side-effectful method blind.
+`toFetchHandler(api)` turns the gateway into a pure WHATWG fetch function for an HTTP server (the shipped Web composition exposes it behind `/api/…` routes), while `InProcessApiClient` runs the same serialization and validation path in-process — the isomorphic point for callers and tests that need the full wire path without a network.
 
-The layering/protocol decisions are recorded in the [GUI layering and RPC protocol RFC](../../../.agents/notes/implemented/architecture/2026-07-19-gui-layering-and-rpc-protocol.md); the browser-side consumption architecture in the [web client architecture RFC](../../../.agents/notes/implemented/architecture/2026-07-19-gui-web-client-architecture.md).
+```text
+const client = new InProcessApiClient(toFetchHandler(ctx.apiProxy))
+const response = await client.sessions.list({})
+```
 
-Question responses are validated against their pending request before the first answer claims it. A multi-select item may carry both requested option labels in `selected` and non-empty `custom` text; a single-select item must use one or the other. Duplicate labels, unknown labels, mismatched ids, incomplete batches, and empty custom text are rejected as `bad-response`.
+The HTTP carrier refuses non-JSON POST bodies with 415 before dispatch, so cross-site simple requests can never run a side-effectful method blind. The browser carrier applies the same Host/Origin checks and signed-cookie authentication to every Host API method ([`dsh-client-connection`](../../client/connection/README.md)); individual Client features may still withhold native or persistent operations on non-loopback pages.
 
-`session.history` reads an attached Session in memory or inspects a cold log through persistence without resuming or publishing an Agent, then pages on append-origin message boundaries. `maxMessages` counts `user/message` and `assistant/message` events that entered the surface by appending, so a model-only replacement copy consumes no quota. Each page stays one contiguous raw event range, which keeps a compaction's log-only `compaction/summary` record on the same page as the replacement that cites it.
+### What the gateway exposes
 
-`session.history`'s tail page (`beforeSeq` absent) additionally carries an optional `projections` block — the watermark snapshot of every unit registered on `ctx.sessionProjections` (`@deepseek-ai/dsh-session-projection`), with `asOfSeq` = the last event seq the values reflect (`-1` on an empty log). The gateway also subscribes to the registry's change feed and mints a `session/projection` mux frame per changed unit (`{sessionId, key, value, seq}` — live push state, never logged; clients hold one generic per-session value store under higher-seq-wins). The carrier holds no other domain's knowledge (each value passed its unit's own schema inside the registry; the wire schemas keep `values`/`value` wide); loadOlder pages never carry the block, and a composition without the registry serves histories without either surface. The gateway owns two units: `sessionListMetadata` caches the monotonic blank-to-nonblank transition and latest human prompt time used by `session.list`, while `imageLimits` publishes the attachments config enforced at prompt admission as a per-boot constant (`apply` keeps the state reference, so baselines alone carry it — no change frames) so clients can refuse an over-limit intake before submit and label upload affordances; the latter activates only while both the registry and the attachments service are composed.
+The API is grouped into domains: `sessions` (list, create, history, prompt, cancel, queue, models, selectModel, rename, fork, search, attachment), `subagents`, `workspace`, `host` (describe, pickDirectory, listDirectory, createDirectory, openPath), `skills`, `agentPresets`, `goals`, `settings`, `credentials`, `llm`, `events`, and `downloads`. The sessions, workspace, and events contracts are owned by the Session Controller, Workspace Controller, and API Remotes packages respectively; the remaining domain contracts and the `RpcMethodMap` live in `src/api/`.
 
-Session-log export is a host-only download surface, not an RPC: `GET /api/session.export?sessionId=…&includeDescendants=true` streams a ZIP whose files are each session's stored artifact text verbatim (the persistence backend's `readRaw` — exact durable bytes decoded from the physical encoding, never a reconstruction from parsed events), root under its original base name plus each subagent descendant under `subagents/<id>/`, and every image any included log references under `media/<attachmentId>.<ext>` (read and verified from the attachment store; a shared image appears once). `HEAD` runs the same root preparation and returns its status and headers without a response body, so browser clients can detect pre-stream failures before handing the GET to the native download manager. Each live root or descendant crosses the authoritative `SessionStore.flush` durability barrier immediately before its raw artifact read; cold sessions have no in-memory work to flush. Compression runs on the host with fflate's streaming Zip API at validated `sessionExportCompressionLevel` 0–9 (default 6), so deployments can trade CPU and latency against archive size; the response is chunked as it is produced and the host never holds the whole archive in one buffer. Once the response queue reaches its 64 KiB byte high-water mark, production waits until consumer pull restores positive capacity; fflate's synchronous callback can overshoot that bound only by the output of one bounded input push. Request abort and response-body cancellation stop lineage and artifact work, terminate the active compressor, and propagate as cancellation rather than an HTTP 500. It requires the persistence, session-query, and attachment services: a deployment without any answers 500, a persistence backend without per-session raw artifacts answers 501, a missing root session answers 404, and a descendant without a stored artifact or a referenced image that cannot be read fails the stream (fail-loud, never silent under-export). The carrier mounts the endpoint; `ApiProxy.downloads.sessionLog` implements it.
+### Sessions and history
 
-Session titles ride the generic projection pair like every other domain — the history-tail `projections` block plus `session/projection` frames under the `title` key. Titles do not join `session.list`; cold sessions remain metadata-only there until opening or resuming attaches their logs. `session.rename` accepts an explicit user title (resuming a cold session first), delegating to `ctx.sessionTitle.rename` — the accepted `session/title` event pins the title against automatic regeneration — and returns the normalized title plus its event seq so a client settles its `title` projection cell ahead of the push frame; a title that normalizes to empty returns `title-invalid`.
+`session.history` pages a session's appended message stream (`maxMessages` counts append-origin `user/message` and `assistant/message` events, so model-only replacement copies consume no quota) and keeps each page a contiguous raw event range, which keeps a compaction's log-only summary on the same page as the replacement that cites it. The tail page optionally carries a `projections` block — the watermark snapshot of every registered projection unit — while the gateway pushes live `session/projection` frames for units whose state changed. `session.search` is a bounded content-search projection over the sessions visible through `session.list`: at most 20 hits, snippets of at most 240 code points, and every hit revalidated against the visible set.
 
-`session.fork` maps an optional event anchor to the first `turn/end` at or after it, letting a message action include that message's whole turn. An omitted or past-end anchor selects the last completed turn; an in-log anchor whose turn remains open returns `fork-unavailable` rather than clipping backward. The published child inherits the source's seeded history, cwd, latest logged `ModelSelection`, and lineage before joining the source Workspace. If Workspace attachment fails, `workspace-attach-failed` carries the already-published child id so clients can reconcile it. The [SessionStore fork decision](../../../.agents/notes/implemented/feature/2026-06-30-session-store-fork-api.md) records why the anchor maps to that `turn/end`.
+### Workspaces and the session list
 
-Session model selection is a session-domain contract. `session.models` returns the current `ModelSelection` separately from provider-grouped advisory models, exact-model reasoning metadata, and provider-local lookup failures. The selection may be absent from the groups and is never injected as a synthetic row; clients can prompt for another selection without turning the directory into a routing whitelist. `session.selectModel` validates the optional adapter-owned reasoning effort and assigns the complete selection for the next prompt assembly. Catalog membership is not validation: an adapter may resolve an unlisted model, while an unavailable provider or unsupported effort returns `model-unavailable`. `session.models` additionally reports `routable`: whether an adapter currently serves the selected provider. This is deliberately not derivable from the groups because an adapter may serve an unadvertised model. `session.prompt` refuses on the same fact with `model-unavailable` before opening a turn; a disabled composer is a client affordance, and the method remains callable.
+`session.list` and `workspace.list` are separate reconnect baselines. Blank sessions stay hidden until the first turn, archiving hides a session from grouping surfaces without touching its log, and registration deletion preserves the directory and session logs. Cold summaries verify blankness by probing a small eligible artifact; a projection-cache miss or stale hint falls back to `createdAt`, so a recently worked large session may sort lower until the next checkpoint.
 
-`session.prompt` and `subagent.prompt` accept optional request-local `clientTimeZone` provenance. When present, the Host validates and canonicalizes `UTC` or an IANA Area/Location before Agent entry, rejects invalid input with `invalid-time-zone`, and records the canonical value on that exact `user-rpc` message beside its `rpcId`. The value is not Session, connection, create, resume, or fork state; non-browser callers may omit it.
+### Exporting sessions
 
-Pending queued input is a live control-plane contract, not conversation history. The gateway derives the complete `next-turn` queue from durable `agent/inbox/spliced` mutations and broadcasts authoritative `session/queue` snapshots after each change and on reconnect; pending `next-step` steering stays outside this Web projection. Within `next-step`, user-origin messages carry the `steering` placement while injected context (approval notices, task completion, attached snapshots) carries `context` and is not surfaced until claimed. The message-local `agent/inbox/inserted`, `claimed`, and `discarded` notifications remain available to lifecycle observers but do not build the queue view. `session.updateQueue` addresses one `MessageId`; edit and remove mutate the attached Agent through `Inbox.splice()`. A claim's pure deletion splice wins races before pre-step admission, so a later operation returns `queue-item-not-found`. `session.cancel` aborts only the active turn and preserves pending inbox work; after cancellation reaches quiescence and the closing turn flushes, AgentLoop claims the next waking message in FIFO order, and the browser never resends or promotes it. Queue operations never resume a cold session, and the client never infers retirement from turn or status events.
+`GET /api/session.export?sessionId=…&includeDescendants=true` streams a ZIP of the session's stored artifact text verbatim, every subagent descendant under `subagents/<id>/`, and each referenced image under `media/<attachmentId>.<ext>`. `HEAD` runs the same root preparation without a body, so browsers detect pre-stream failures before handing the GET to the download manager. The response is chunked as it is produced, and `sessionExportCompressionLevel` (0–9, default 6) trades CPU and latency against archive size. Missing persistence, session-query, or attachment services answer 500, a backend without per-session raw artifacts 501, and a missing root session 404.
 
-Background jobs ride the same live-push posture. When `ctx.jobs` is composed, the gateway subscribes to its change feed and broadcasts a whole `session/jobs` snapshot after every registry commit that alters what a session can see — registration, the stopping transition, settlement, and owner-disposal removal — plus a subscription baseline for each session that already has tasks (an absent baseline is the empty set; a change that empties a set still sends `[]`). A change carrying an owner reads through that exact `Agent`, so a push stays correct while its scope tears down; the baseline reads `ctx.agents.get(sessionId)`, which yields only unowned tasks for a session with no live Agent and never resumes a cold one. An unowned change fans out to every subscribed session, because unowned tasks are visible to every caller. The wire `JobView` drops `ownerSession`, `reported`, and `outputLimitBytes`: the frame's own `sessionId` carries the first, and the other two are internal notice and model-presentation policy. A composition without the registry emits no such frames.
+### Model selection, presets, commands, and configuration
 
-Workspace and Session lists are separate reconnect baselines. `workspace.create({ path })` adopts an existing canonical directory and permits basename-derived titles to repeat. `workspace.insertBefore({ workspaceId, beforeWorkspaceId? })` commits one registry-order move and answers the complete order; a pure reorder emits `host/workspace-order-changed` with that complete order, while unknown sources or anchors return `workspace-not-found`. `workspace.delete` removes only the Workspace registration, `session.create` accepts an optional preallocated Session id, and `host/workspace-changed`, `host/workspace-removed`, plus `host/session-added` carry committed increments in either arrival order. `workspace.archiveSession` adds one session to the registry-global archive set and answers the full updated set; `workspace.list` carries that set as the reconnect baseline and `host/archived-sessions-changed` pushes the full snapshot after every durable change. Archiving hides the session from grouping surfaces without touching its log or its workspace account; a session neither live nor persisted fails with `session-not-found`. Registration deletion preserves the directory and session logs; its Sessions remain in `session.list` and become Ungrouped. `SessionSummary.blank` and the `host/session-added` frame carry whether a turn has started: clients hide blank sessions and reuse them per workspace, flip blank on the first `host/session-status(running:true)`, and treat `session.list` as the reconnect authority. Attached summaries fold the live log. A cold summary trusts cached `blank: false`, but treats cached `true` and a cache miss as unverified; when `locate()` reports an artifact no larger than the `coldBlankProbeMaxBytes` eligibility threshold (default 1 KiB), the gateway reads that Session with `readFrom()` and folds both blankness and the latest human prompt. A larger, location-less, vanished, or unreadable artifact remains visible. After an asynchronous cold read, a Session that attached meanwhile is summarized from its live log instead. `updatedAt` uses the live fold, the exact small-artifact fold, or the projection cache in that order, falling back to `createdAt`; pickup boundaries and other writes never promote a Session.
+`session.models` reports the current `ModelSelection` separately from provider-grouped advisory models, and `session.selectModel` saves an accepted switch as the deployment default through the shared `agent-default-model` settings section — a default naming an unavailable provider still reaches the selector as `current` instead of being silently replaced. Each access resolves an in-process selection first, then the session's latest `request/header`, then the deployment default. A logged reasoning effort marked as an adapter default remains absent from the restored selection, so the next resolution does not promote it into an explicit choice or record a false header change. `agentPreset.list` exposes the deployment's preset roster with each row's `trust` and a `broken` reason when a preset cannot compose a session; `agentPreset.select` swaps a blank session's composition and is refused once a turn has run. `skill.list` serves the composer menu with each skill's `modelInvocable` flag, and `command.execute` runs a slash command with pure admission semantics whose outcome rides the logged `command/run`/`command/done` pair. The `settings.*`, `credentials.*`, and `llm.*` domains are the configuration-page wire: `settings.describe` returns each namespace's schema and redacted layered values, `settings.mutate` is the removal path for a client holding the redacted view, secrets never ride any response, and `llm.discoverModels` interrogates a provider endpoint the page is still drafting without writing anything.
 
-`session.search` is a bounded content-search projection over the sessions visible through `session.list`. The gateway asks the optional `ctx.sessionQuery` service for globally ranked current-surface user, assistant, and steering matches, consumes that stream until it has at most 20 visible session/snippet pairs plus one lookahead, and revalidates every hit against the list-derived authorization set before returning it. Provider pages start at 20 hits; when a first-page request rejects that limit, the gateway probes 10, 5, 2, then 1 and retains the learned size for continuation and stale-generation restarts. Returned snippets contain at most 240 Unicode code points, and the response schema independently enforces that bound at each client boundary. Keeping the authorization set in Host memory avoids SQLite's variable ceiling for large valid corpora without weakening visibility or ranking.
+### Configuration
 
-A stale continuation discards every partial result, deduplication entry, and cursor from that provider attempt, then restarts at the first page against the original list-derived visibility snapshot without discarding the learned provider page size. Limit probes and stale retries share the same limit of at most 100 provider calls (and therefore at most 2,000 inspected hits); a page larger than its requested limit, a repeated continuation cursor, or a still-unexhausted stream at that call budget fails closed as an `internal` business error. The carrier request signal cancels persistence listing, cold-summary collection, and every search call, including a limit or stale rejection observed concurrently with cancellation. A deployment without the service, or any unrecovered index/query failure, also returns an `internal` business error so clients can retain metadata-only matches.
+| Field | Default | Meaning |
+|---|---|---|
+| `nativeOpen` | platform-detected | Whether the deployment can hand paths to a native desktop opener |
+| `sessionExportCompressionLevel` | `6` | DEFLATE level for every session-log ZIP entry, 0–9 |
 
-Directory picking delegates to the composed `ctx.directoryPicker` backend ([the directory-picker seam](../directory-picker/README.md)); a method called outside the composed capability's kind fails with `directory-picker-unavailable` (the client needs no advertisement — the composed picker package's own client half renders the matching interaction). Under `native`, `host.pickDirectory` opens one native chooser and returns its selected path (`null` on cancel); this user-paced method does not use the default 30-second unary timeout, while caller/connection aborts still propagate to the native process. Under `browse`, `host.listDirectory` returns one name-sorted directory level with breadcrumb ancestry, a `home` anchor, and host-owned `hidden` flags (absent path = home directory), and `host.createDirectory` creates one validated child segment; the backend's typed failures map 1:1 onto the `directory-unreadable`/`directory-exists`/`directory-create-failed` codes. The browser carrier's prefix-wide trust fence (dsh-client-connection) covers all of these like every other `/api` request.
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-host-apiproxy) is the exhaustive source for every accepted field and its JSDoc.
 
-`host.openPath` opens a filesystem path with the operating system's default application (`open` on macOS, `Invoke-Item` on Windows, and `xdg-open` on desktop Linux). For `.html`, `.htm`, `.xhtml`, and `.svg`, macOS and desktop Linux prefer a named default browser and fall back to that application handoff when none can be named. WSL translates every Linux path through `wslpath -w` and hands the resulting Windows/UNC path to Windows `Invoke-Item`, including browser-renderable documents, instead of assuming a Linux desktop association. `host.describe.home` is the host account home directory. The Web client uses it to display POSIX home-rooted paths as `~`; Windows values are still reported and are not abbreviated. `host.describe.canOpenPath` advertises whether that handoff can reach a user-visible desktop: explicit gateway `nativeOpen` wins, an injected opener is usable by definition, and platform detection otherwise accepts macOS, Windows, WSL, or Linux with a display while rejecting headless/container Linux. The browser carrier applies the same Host/Origin checks and signed-cookie authentication as every Host API method; clients combine the capability facts before presenting a native action.
+-----
 
-The `agentPreset.list` domain exposes the deployment's preset roster so a browser can offer a choice when starting a session; each row carries its `trust` (a `user` preset is exactly as privileged as the plugins it names), whether it is the current default, and — when the preset cannot compose a session — a `broken` reason, because a damaged directory still occupies its id and a surface must be able to show and delete it rather than offer it and fail the session start. A deployment composing no presets answers with an empty roster rather than an error, because sharing the host composition is a valid deployment. `agentPreset.select` recomposes one session's agent from a different preset, and is allowed only while the session is blank: once a turn has run, that history was produced under the preset's tools and swapping them would strand logged tool calls, so the attempt answers `agent-preset-locked`. The agent and the session survive — only the composition is swapped, and a failed swap restores the previous one.
+<a id="understand-the-implementation"></a>
+## Understand the implementation
 
-`agentPreset.read`, `copy`, `openDocument`, and `remove` manage the compositions themselves. `read` reports the text with its `trust`, for the read-only viewer. Authoring is copy-only: `copy` takes `{ from, agentPreset, name? }` — two ids the Host resolves against its own roots plus an optional display name — and copies the source's whole directory, so no composition text crosses the wire and a copy is exactly as loadable as its source; an uncontainable or already-taken id answers `agent-preset-invalid`, and `remove` refuses a shipped preset as `agent-preset-read-only`. `openDocument` hands one locally authored preset's DIRECTORY to the platform opener — the request carries an id, never a path, so no browser payload can select an arbitrary filesystem target; where the deployment has no native opener the reply is `{ opened: false, path }` for the surface to show as text, a shipped preset is refused like `remove`, and the gateway's `nativeOpen` config pins the capability where platform detection (`canOpenNativePath`) would mislead. [`dsh-client-connection`](../../client/connection/README.md) authenticates these methods with `list`, `select`, and the complete Host API. A composition still names the plugins a session runs, so reading one is reconnaissance and copy/remove/openDocument manage the roster and drive the host desktop. `list` reports two path-free capability flags: `authorable`, whether the deployment configures a root a new preset could be copied to, and `hasDocument`, whether `openDocument` would open natively rather than answer a path.

+<summary>Implementation internals — click to expand</summary>
 
-The `command.*` and `skill.*` domains expose the host command registry and skill catalog to clients. Every method addresses one session's agent by `sessionId` (a served session always has an Agent; `command.*` resumes cold sessions through the same path as `session.*`, while `skill.list` resolves the project root from the session header without touching the Agent registry). `skill.list` serves the composer's menu: it returns every user-invocable skill with its `modelInvocable` flag, so menus can mark user-only (`disable-model-invocation`) entries whose only invocation path is the slash gesture. Listing is the skill domain's only RPC — invocation itself is an ordinary `session.prompt` whose whitespace-bounded `/name` tokens `dsh-tool-skill` recognizes at the pre-step boundary and answers with injected `<skill_content>` context, so every entry point (Web, TUI, and ACP) shares one deterministic path—including for hand-typed text—with no dedicated invocation wire. `command.execute` runs a slash-command line host-side with pure admission semantics: the response reports whether the line resolved to a handler plus the minted lifecycle `commandId` when it did (correlating the acknowledgment with the flow node), while the outcome rides the durably logged `command/run`/`command/done` lifecycle pair broadcast on the mux stream. Command handlers may legitimately outlast the 30-second transport health deadline, so `command.execute` carries only caller/connection cancellation; that signal cancels the running handler. `commands/change` rides the forwarded-event frame as the registry-wide catalog invalidation signal: clients refetch `command.list` instead of diffing. Forwarded `agent-preset/selected` is its per-session counterpart, emitted from the logged selection commit: recomposing a blank session's agent re-parents its scope without registering anything, so both catalogs that session's composition decides (`command.list`, `skill.list`) go stale with no registry change to announce it.
+### Design concept
 
-The `settings.*`, `credentials.*`, and `llm.*` domains are the configuration-page wire. The settings domain serves every registered namespace: a plugin distributed outside this repository becomes browser-configurable by registering its section, with no change here, and this proxy adds no boundary of its own — a name no registration answers folds into the seam's own `settings-rejected`. Which surface renders a namespace is the browser's decision (the plugin configuration page keys its cards on the namespace), never this proxy's. `settings.describe` returns each namespace's serialized schemastery schema, redacted layered values (resolved/`base`/`user` — a field's presence in `user` marks it user-overridden), the `secrets` slot list, the section's `revision`, and the boolean `hasDocument` capability flag. The browser receives no Host path: pathless `settings.openDocument` asks the provider to materialize its document and then hands the Host-resolved result to the native opener, so no browser payload can select any filesystem target. `settings.update`/`settings.replace` write the user layer; `settings.mutate` applies path ops (`set`/`unset`) against the section as stored, which is the removal path for a client holding the redacted view — rebuilding a section from it and replacing wholesale would delete the secrets the wire never returned. Any write may carry `expectedRevision`; a stale one answers `settings-conflict` with both revisions rather than overwriting the writer that landed first, and every other seam refusal folds into `settings-rejected`. Secret-role values never ride any response in any layer; a secret crosses the wire in exactly one direction — inside an `update`/`mutate` payload or `credentials.set`. `credentials.describe` returns value-free views (`configured`/`source`/`writable`), and `credentials.set`/`credentials.unset` map a shadowed-reference refusal onto `credential-rejected`. `llm.providers` merges the configurable-provider directory with live routes (dormant entries carry `active: false`; undeclared live routes append with no settings address) and `llm.models` is the session-independent catalog. `llm.discoverModels` interrogates a provider endpoint the page is still drafting: `settingsNs` selects the adapter family that knows how to read the listing, and the endpoint, protocol, and key come from the form rather than from storage. It writes nothing — the reply is candidates, and only a later `settings.mutate` decides what a route serves — so its `apiKey` is the third payload on which a secret may ride, alongside `settings.update`/`mutate` and `credentials.set`. The host never stores or returns it; like the other two it does ride the client's outgoing envelope, which `subscribeEnvelopes()` observers can see, and redacting that tap is a configuration-plane-wide change rather than this method's to make alone. Every refusal (an unserved namespace, a protocol with no readable listing, an unreachable endpoint, a rejected credential) folds into `model-discovery-failed`, whose message is the adapter's own text and whose details name the endpoint asked but never the credential offered. Invalidations keep every surface converged without polling. `settings/document-updated` and `credentials/reference-updated` ride the verbatim forwarded-event frame (see below), so a raw settings change whose resolved value is unchanged still reaches clients, and a credential invalidation still carries reference names only, never values. `llm/adapters-updated` is forwarded beside `settings/document-updated`; concrete model consumers subscribe to both owner events directly because topology commits and settings documents can independently change their directories. Connection authenticates the whole configuration plane, reads and native actions included, with the same browser session as every Host API method. A composition without a settings or credential provider answers those domains with an actionable `internal` error naming the missing plugin.
+The package is built on one separation: the API contract is channel-independent, and physical transports are carriers around it. Wire messages form a two-member discriminated union — `ClientRequest` (the POST `/api/<method>` body) and `ServerResponse` (that POST's response body) — decoupled from the physical channel. Responses always echo the matching request's `rpcId` and never mint a new one. Business errors ride the `RpcResult` error branch with a closed `RpcErrorDetailsMap`; HTTP status expresses only the carrier. The layering and protocol decisions are recorded in the [GUI layering and RPC protocol RFC](../../../.agents/notes/implemented/architecture/2026-07-19-gui-layering-and-rpc-protocol.md).
 
-## Carrier layer (`/client` + root)
+### Source map
 
-`AbstractApiClient` holds every protocol invariant — rpcId minting, envelope wrap/unwrap, zod parsing, SSE frame decoding, unary timeout, microtask-batched envelope observation (`subscribeEnvelopes`) — while platform subclasses supply only the `doFetch` transport aspect. `InProcessApiClient` over `toFetchHandler(api)` remains the isomorphic point for callers and carrier tests that need the full wire serialization/validation path without a network. Product `dsh --profile headless` is a direct core entry point and does not mount this package.

+### The gateway service
+
+`ApiProxyService` provides `ctx.apiProxy` and implements the contract over the composed host context — sessions, subagents, workspace registry, directory picker, agent presets, settings, credentials, LLM, events, and downloads. The Host cwd is the default project directory. The gateway consumes `ctx.agentDefaultModel` only for the deployment metadata `host.describe` reports; `session.selectModel` (Session Controller) saves an accepted switch as the deployment default through the shared agent-default-model settings section. Product `dsh --profile headless` is a direct core entry point and does not mount this package.
+
+### Request flow
+
+A request enters a carrier, which parses the envelope and the business payload in two levels, dispatches per method, and returns a response echoing the request's `rpcId`. Server pushes — the session and workspace follow streams — ride the API Gateway's `/api/remote.mux` WebSocket and deliver `opened` then gap-free `event` frames the client decodes. Unary requests carry the carrier's abort signal, so caller/connection cancellation propagates to the underlying work.
+
+### What the gateway owns
+
+The gateway is the wire contract plus a host-side projection over services owned elsewhere: it emits no cordis events, and the session/agent event streams it projects are asserted by their owning packages' companions. The carrier holds no other domain's knowledge — each projection value already passed its unit's own schema inside the registry.

 ## Known Limitations and Deferred Work
 
-- **Forwarded Remote events are parasitic on this legacy frame union** — `host/remote-event` lives in `HostFrame` so the delivery path could reuse the existing host stream instead of opening a third downlink, which makes it read as if this package owned the Remote event contract. It does not: the allowlist is `dsh-api-remotes`' and the consumer verb is `ctx.remote.$on`. When the host stream moves off this package, the frame moves with it and the consumer contract is unaffected ([rationale](../../../.agents/notes/implemented/architecture/2026-08-10-remote-event-delivery.md)).
-- **Pending-interaction state is host-side** — the wire uses POST `/api/respond` plus `RpcReceipt`; the table in `src/api-proxy.ts` handles questions only and has no approval entries.
-- **A pending question does not survive a host restart** — the registry holds the awaiting tool call's own `resolve`/`reject`, so it is host-process memory. `events.mux` replays every still-pending question on each reopen, which covers a browser reload or a reconnect; a host restart takes the awaiting turn with it, and the reopened Session offers no composer for that question. Restoring one across a host restart needs a durable pending-interaction record and is deferred.

 - **No protocol version field** — client and host ship together; `host.describe` gains a version negotiation field only when an independently released client exists.

 - **Linux native picker requires desktop tooling** — under the `native` capability, `host.pickDirectory` reports an actionable error when neither Zenity nor KDialog is installed; the browse backend is the composition-level fallback (see the [native backend README](../directory-picker-native/README.md)).
-- **Cold-list hints degrade only toward visibility and older ordering** — a projection-cache miss or stale `lastPromptAt` falls back to `createdAt` unless an eligible small artifact supplies an exact fold, so a recently worked large Session may sort too low until the next checkpoint. A blank artifact larger than `coldBlankProbeMaxBytes`, or one from a backend without `locate()`, remains visible. The threshold is checked before `readFrom()` rather than enforced by persistence, so concurrent artifact growth may increase one probe's read cost without changing blankness safety.

A protocol version field waits for an independently released client; a multi-user carrier must replace provider search diagnostics with public-safe text; per-connection picker adaptivity (native for a local browser, browse for a remote one) remains an undecided direction for the host surface.

 # @deepseek-ai/dsh-host-apiproxy
 
 [English](README.md) | 中文
 
-所有客户端共用的 API 网关由三部分组成：TypeScript API 约定（`src/api/`，不依赖 Node，可从浏览器导入）、fetch 载体对（`src/fetch/`：宿主侧的 `toFetchHandler`，以及客户端侧的 `AbstractApiClient` 与平台子类）和宿主侧实现（`src/api-proxy.ts`：`createApiProxy` 加上默认导出的 `ApiProxyService` 网关插件，其配置为 `{nativeOpen?, sessionExportCompressionLevel?, coldBlankProbeMaxBytes?}`，提供 `ctx.apiProxy`）。该包不注册任何路由；HTTP 等载体自行包装 `ctx.apiProxy`。随发行版交付的 Web 组合位于 [`packages/bundle/web-app/cordis.patch.yml`](../../bundle/web-app/cordis.patch.yml)，其默认 Agent（智能体）模型选择属于 base 组合包中的 [`@deepseek-ai/dsh-agent-default-model`](../../core/agent-default-model/README.zh.md)。
+## 概述
 
-## 共享 Agent 默认值（`agent-default-model` Settings 分节）
+web GUI 宿主的每个客户端都通过 `dsh-host-apiproxy` 调用同一套类型化 API——会话与历史、子代理、工作区、目录选择、模型选择、agent preset、skill、目标、设置、凭据、LLM 目录、事件与会话导出——由 fetch 载体经由 HTTP 或进程内搬运。约定层零 Node 依赖、可从浏览器导入，因此一套类型化 API 同时服务 Web 服务器、Electron 与任何未来的客户端形态。随发行版交付的 Web 组合在 [`dsh-web-app`](../../bundle/web-app/README.zh.md) 中组装网关。选择载体、调用领域 API 与配置网关在前；协议内部细节放在下方可折叠的开发者章节中。
 
-`ApiProxyService` 消费 `ctx.agentDefaultModel`；它不持有提供方／模型配置或 Settings 分节。共享服务在 `agent-default-model` 下注册 `{provider, model, reasoningEffort?}`：base 组合包的组合条目是底层，`settings.yaml` 把用户选择叠加其上。
+## 目录
 
-会话每次访问时都按三级解析模型选择：本进程内作出的选择，其次是该会话日志中最新的 `request/header`，最后是这个默认值。已经跑过一轮的会话从自己的日志推导选择，空白会话则能观察到创建之后保存的默认值。若日志中的推理强度被标记为适配器默认值，恢复的选择仍不包含该强度，因此下一次模型解析不会把这个默认值提升为显式选择，也不会记录虚假的 header 变更。

-`session.selectModel` 会把接受的切换保存为部署默认值；没有单独的选择动作。它存储已解析的 `ModelSelection`，包括适配器实体化的默认推理（reasoning）强度。完整分节写入会在所选模型没有推理强度时清除已存值。存储失败只记日志，不会撤销会话选择。没有设置提供方的部署保留组合条目，切换只对当前会话生效。
+-----
 
-Settings 分节中的 `reasoningEffort` 在 agent-default-model 插件配置中刻意没有对应字段：seam 按字段把用户层合并到组合条目之上，因此缺席的键无法覆盖已有键，组合层中的推理强度会在以后选择没有推理强度的模型时继续存在。推理强度的部署默认值属于按模型解析的适配器 profile。
+<a id="use-this-package"></a>
+## 使用本包
 
-存储的选择独立于目录成员关系。默认值指向不可用的提供方时，它仍会作为会话的 `current` 送到 `session.models`，让选择器请求用户重新选择，而不是静默选用其他模型。反过来，适配器也可以服务其目录中未公布的模型。
+当 GUI 宿主的客户端需要会话、工作区与配置 API 时组合网关：加载 `ApiProxyService`，把 `ctx.apiProxy` 包进一个载体，然后调用类型化的领域方法。
 
-## 约定层（`/api`）
+### 选择载体
 
-协议消息组成一个四象限可辨识联合：发起方 × 请求／响应，与物理通道解耦。四种消息分别是 `ClientRequest`（POST `/api/<method>` 的请求体）、`ServerResponse`（该 POST 的响应体）、`ServerRequest`（SSE（Server-Sent Events）帧）和 `ClientResponse`（POST `/api/respond` 的请求体）。响应始终回显对应请求的 `rpcId`，绝不签发新值。方法的参数与返回值结构只存在于领域接口签名（`SessionsApi`、`HostApi`、`EventsApi`）中；`RpcMethodMap` 注册方法，其他所有位置均通过 `RequestPayload<K>`／`ResponseValue<K>` 派生。Zod schema 以 `satisfies z.ZodType<Wire<T>>` 锚定类型，并分两层解析：先解析信封，再解析业务载荷，随后按方法分发。业务错误由 `RpcResult` 的错误分支承载（`RpcErrorDetailsMap` 封闭错误码集合）；HTTP 状态只表达载体层结果。每个 `/api` POST 都必须声明 `application/json` 媒体类型——否则在分发前即以 415 拒绝，因此跨站「简单请求」（浏览器不经 CORS 预检就会发出）永远无法盲目执行有副作用的方法。
+`toFetchHandler(api)` 把网关变成纯 WHATWG fetch 函数，供 HTTP 服务器使用（随发行版交付的 Web 组合把它暴露在 `/api/…` 路由之后）；`InProcessApiClient` 则在进程内运行同一条序列化与校验路径——这是需要完整协议路径但不需要网络的调用方与测试的同构接点。
 
-分层与协议决策记录在 [GUI 分层与 RPC 协议 RFC](../../../.agents/notes/implemented/architecture/2026-07-19-gui-layering-and-rpc-protocol.zh.md) 中；浏览器侧消费架构记录在 [Web 客户端架构 RFC](../../../.agents/notes/implemented/architecture/2026-07-19-gui-web-client-architecture.zh.md) 中。
+```text
+const client = new InProcessApiClient(toFetchHandler(ctx.apiProxy))
+const response = await client.sessions.list({})
+```
 
-首个回答认领待处理请求之前，系统会对照该请求校验问题响应。多选题的回答项可以同时携带 `selected` 中的请求选项标签与非空 `custom` 文本；单选题的回答项必须二选一。标签重复、标签未知、id 不匹配、批次不完整以及自定义文本为空都会以 `bad-response` 拒绝。
+HTTP 载体在分发前以 415 拒绝非 JSON 的 POST 请求体，因此跨站「简单请求」永远无法盲目执行有副作用的方法。浏览器载体对每个 Host API 方法实施相同的 Host/Origin 检查与签名 cookie 认证（[`dsh-client-connection`](../../client/connection/README.zh.md)）；各 Client 功能仍可以在非 loopback 页面上拒绝原生操作或持久化操作。
 
-`session.history` 会读取已附加 Session 的内存状态，或通过持久化检查冷日志，而不会恢复或发布 agent，然后按追加来源的消息边界分页：`maxMessages` 统计以追加方式进入 surface 的 `user/message` 和 `assistant/message` 事件，因此仅供模型使用的替换副本不占用配额。每一页仍是一段连续的原始事件区间，从而让压缩（compaction）的仅日志 `compaction/summary` 记录与引用它的替换留在同一页。
+### 网关暴露什么
 
-`session.history` 的尾页（不带 `beforeSeq`）额外携带一个可选的 `projections` 块——`ctx.sessionProjections`（`@deepseek-ai/dsh-session-projection`）上每个已注册单元的水位线快照，`asOfSeq` = 这些值共同反映到的最后一个事件 seq（空日志为 `-1`）。网关还订阅注册表的变更流，为每个状态发生变化的单元生成一个 `session/projection` mux 帧（`{sessionId, key, value, seq}`——实时推送状态，绝不入日志；客户端按 seq 高者胜维护一个按会话的通用值仓）。载体不持有其他领域的知识（每个值在注册表内部已过其单元自己的 schema；协议 schema 对 `values`/`value` 保持宽松）；loadOlder 页永不携带该块，未装注册表的组合则两个面都不提供。网关拥有两个单元：`sessionListMetadata` 缓存用于 `session.list` 的单调 blank→nonblank 转换与最新真人 prompt 时间；`imageLimits` 则把 prompt 准入时执行的 attachments 配置作为每次启动恒定的值发布（`apply` 保持状态引用不变，因此只靠基线携带、绝不产生变更帧），供客户端在提交前拒绝超限的加入并给上传入口标注上限，后者仅在注册表与 attachments 服务同时组合时激活。
+API 按领域分组：`sessions`（list、create、history、prompt、cancel、queue、models、selectModel、rename、fork、search、attachment）、`subagents`、`workspace`、`host`（describe、pickDirectory、listDirectory、createDirectory、openPath）、`skills`、`agentPresets`、`goals`、`settings`、`credentials`、`llm`、`events` 与 `downloads`。sessions、workspace 与 events 契约分别归 Session Controller、Workspace Controller 与 API Remotes 包所有；其余领域契约与 `RpcMethodMap` 位于 `src/api/`。
 
-会话日志导出是宿主侧的下载面，不是 RPC：`GET /api/session.export?sessionId=…&includeDescendants=true` 流式返回一个 ZIP，其中每个文件都是会话存储工件的逐字原文（持久化后端的 `readRaw`——按物理编码解码的确切持久化字节，绝非从解析后事件重建），根会话放在其原始基础文件名下，每个子代理后代放在 `subagents/<id>/` 下，每个被任何包含的日志引用的图片放在 `media/<attachmentId>.<ext>` 下（从附件存储读取并校验；共享图片只出现一次）。`HEAD` 会执行相同的根工件准备，并在没有响应 body 的情况下返回状态与响应头，使浏览器 Client 可以在把 GET 交给原生下载管理器前发现流式传输前的失败。每个实时根会话或后代都会在读取原始工件前立即通过权威的 `SessionStore.flush` 持久性屏障；冷会话没有需要 flush 的内存工作。压缩在宿主侧使用 fflate 流式 Zip API 和已验证的 `sessionExportCompressionLevel` 0–9（默认 6），使部署可以在 CPU／延迟与归档大小之间取舍；响应边生成边分块写出，宿主从不把整个归档放进单个缓冲区。响应队列达到 64 KiB 字节高水位后，生产会等待 Consumer pull 恢复正容量；fflate 的同步回调最多只会让该界限多出一次有界输入 push 的输出。请求中止或响应 body 取消会停止血缘与工件工作、终止活跃压缩器，并继续按取消传播，而不会变成 HTTP 500。它要求同时挂载持久化、session-query 与附件服务：任一缺失应答 500，持久化后端不提供每会话原始工件时应答 501，根会话缺失时应答 404，后代缺少存储工件或引用的图片无法读取则整个流失败（fail-loud，绝不静默少导出）。端点由传输层挂载，`ApiProxy.downloads.sessionLog` 实现它。
+### 会话与历史
 
-会话标题与其他所有领域一样搭乘这对通用投影机制——历史尾页的 `projections` 块外加 `title` 键下的 `session/projection` 帧。标题不会加入 `session.list`；冷会话在其中仍只有元数据，直到打开或恢复操作附加其日志。`session.rename` 接受用户显式标题（冷会话先恢复），委托给 `ctx.sessionTitle.rename`——被接受的 `session/title` 事件将标题钉住、不再被自动生成覆盖——并返回规范化后的标题及其事件 seq，让 client 在推送帧到达前就结算自己的 `title` 投影格；规范化后为空的标题返回 `title-invalid`。
+`session.history` 对会话的追加消息流分页（`maxMessages` 统计以追加方式进入 surface 的 `user/message` 与 `assistant/message` 事件，因此仅供模型使用的替换副本不占用配额），并让每一页保持一段连续的原始事件区间，这使压缩的仅日志摘要与引用它的替换留在同一页。尾页可选携带 `projections` 块——每个已注册投影单元的水位线快照——网关会为状态发生变化的单元推送实时的 `session/projection` 帧。`session.search` 是对 `session.list` 可见会话的有界内容搜索投影：至多 20 个命中、每个摘要至多 240 个码点，且每个命中都对照可见集合重新校验。
 
-`session.fork` 将可选事件锚点映射到该锚点处或其后的首个 `turn/end`，使消息操作可包含该消息所在的完整轮次。锚点省略或超过末尾时，选择最后一个已完成轮次；若锚点已在日志中，而其所在轮次仍开放，则返回 `fork-unavailable`，不会向较早位置裁剪。发布后的子会话会先继承源会话的种子历史、cwd、日志中最新的 `ModelSelection` 及谱系，再加入源 Workspace。如果附加到 Workspace 失败，`workspace-attach-failed` 会携带已发布的子会话 id，供客户端对账。[SessionStore fork 决策](../../../.agents/notes/implemented/feature/2026-06-30-session-store-fork-api.zh.md)记录了为何锚点要映射到该 `turn/end`。
+### 工作区与会话列表
 
-会话模型选择属于会话领域约定。`session.models` 将当前 `ModelSelection` 与按提供方分组的建议性模型、精确模型的推理元数据和逐提供方查询失败记录分开返回。该选择可能不在这些分组中，也绝不会作为合成行注入；客户端可以提示用户作出另一项选择，而无需把目录变成路由白名单。`session.selectModel` 校验由适配器持有的可选推理强度，并指定下次组装提示词时使用的完整选择。目录成员关系不构成校验：适配器可以解析未列出的模型，而不可用的提供方或不受支持的推理强度会返回 `model-unavailable`。`session.models` 还会报告 `routable`，即当前是否有适配器为所选提供方提供服务。该值刻意不从分组推导，因为适配器可以服务未公布的模型。`session.prompt` 会依据同一事实，在开启轮次之前以 `model-unavailable` 拒绝；客户端禁用 composer 只是提示性设计，这个方法始终可被调用。
+`session.list` 与 `workspace.list` 是彼此独立的重连基线。空白会话在首轮开始前保持隐藏，归档会把会话从分组表面隐藏而不触碰其日志，注销注册则保留目录与会话日志。冷摘要通过探测一个小型合格工件来验证空白状态；projection cache miss 或陈旧提示会回退到 `createdAt`，因此最近工作过的大型会话可能在下一个 checkpoint 前排得偏低。
 
-`session.prompt` 和 `subagent.prompt` 接受可选的请求本地 `clientTimeZone` 来源信息。若提供该值，Host 会在进入 Agent 前校验 `UTC` 或 IANA Area/Location 并将其规范化；无效输入以 `invalid-time-zone` 拒绝，规范值则与 `rpcId` 一起记录在这条确切的 `user-rpc` 消息上。该值不属于 Session、连接、create、resume 或 fork 状态；非浏览器调用方可以省略它。
+### 导出会话
 
-待处理的 queued 输入属于实时控制平面约定，而非对话历史。网关根据持久 `agent/inbox/spliced` 变更派生完整的 `next-turn` 队列，并在每次变更后及重连时广播权威 `session/queue` 快照；待处理的 `next-step` steering（中途引导）不进入此 Web 投影。在 `next-step` 内，用户来源的消息携带 `steering` placement，而注入上下文（审批通知、任务完成、附加快照）携带 `context`，领取前不对外呈现。面向单条消息的 `agent/inbox/inserted`、`claimed` 与 `discarded` 通知仍供生命周期观察方使用，但不用于构建队列视图。`session.updateQueue` 通过 `MessageId` 寻址单个项；编辑和移除经已挂载 Agent 的 `Inbox.splice()` 修改队列。认领操作的纯删除 splice 会在 pre-step 准入前赢得竞态，因此之后的操作返回 `queue-item-not-found`。`session.cancel` 仅中止活动轮次并保留待处理 inbox 工作；取消达到完全停稳且结束中的轮次完成 flush 后，AgentLoop 按 FIFO 顺序认领下一条可唤醒消息，浏览器绝不重发或提升它。队列操作绝不恢复冷会话，客户端也绝不根据轮次或状态事件推断某项已退出队列。
+`GET /api/session.export?sessionId=…&includeDescendants=true` 流式输出一个 ZIP，其中每个会话的已存工件文本原样包含，每个子代理后代位于 `subagents/<id>/` 下，每张被引用的图片位于 `media/<attachmentId>.<ext>` 下。`HEAD` 在无请求体的情况下运行同样的根准备，因此浏览器能在把 GET 交给下载管理器之前检测到流前失败。响应边生成边分块输出，`sessionExportCompressionLevel`（0–9，默认 6）在 CPU 与延迟之间权衡归档大小。缺少 persistence、session-query 或 attachment 服务时回答 500，后端没有按会话原始工件时回答 501，根会话缺失时回答 404。
 
-后台任务沿用同一种实时推送姿态。当组合中有 `ctx.jobs` 时，网关订阅它的变更订阅，并在注册表每一次改变某个会话可见内容的提交后——注册、转入 stopping、结算，以及 owner 销毁时的移除——广播一份完整的 `session/jobs` 快照，另外为每个已经有任务的会话发送订阅 baseline（没有 baseline 即表示空集；把集合清空的那次变更仍然发送 `[]`）。带 owner 的变更通过那个确切的 `Agent` 读取，因此推送在其 scope 拆除期间依然正确；baseline 读 `ctx.agents.get(sessionId)`，对没有活体 Agent 的会话只得到无主任务，且绝不恢复冷会话。无主变更向每一个已订阅会话扇出，因为无主任务对所有调用方可见。线路上的 `JobView` 丢弃 `ownerSession`、`reported` 和 `outputLimitBytes`：第一个由帧自身的 `sessionId` 携带，另外两个分别是内部通知位和模型呈现策略。没有该注册表的组合不发出这类帧。
+### 模型选择、preset、命令与配置
 
-Workspace 列表与 Session 列表是相互独立的重连基线。`workspace.create({ path })` 会接纳已有的规范目录，并允许由 basename 派生的标题重复。`workspace.insertBefore({ workspaceId, beforeWorkspaceId? })` 提交一次注册表顺序移动并应答完整顺序；单纯重排序会通过 `host/workspace-order-changed` 推送同一份完整顺序，而未知来源或锚点返回 `workspace-not-found`。`workspace.delete` 只移除 Workspace 注册记录，`session.create` 接受可选的预分配 Session id，`host/workspace-changed`、`host/workspace-removed` 与 `host/session-added` 则以任意到达顺序携带已提交的增量。`workspace.archiveSession` 向注册表级全局归档集合添加一个会话，并应答完整的更新后集合；`workspace.list` 携带该集合作为重连基线，`host/archived-sessions-changed` 在每次持久变更后推送完整快照。归档只把会话从各分组视图中隐藏，不触碰其日志和 workspace 记账；既非活动会话也未持久化的会话以 `session-not-found` 失败。删除注册记录会保留目录和会话日志；相关 Session 仍留在 `session.list` 中，并进入 Ungrouped。`SessionSummary.blank` 与 `host/session-added` 帧携带是否已开始过轮次：客户端隐藏空白会话并按 workspace 复用它们，在首个 `host/session-status(running:true)` 时翻转 blank，并以 `session.list` 作为重连权威。已附加摘要折叠实时日志。冷摘要信任缓存的 `blank: false`，但把缓存的 `true` 与 cache miss 都视为未经验证；当 `locate()` 报告的工件不大于 `coldBlankProbeMaxBytes` 资格阈值（默认 1 KiB）时，网关通过 `readFrom()` 读取该 Session，同时折叠空白状态与最新真人 prompt。更大、无位置、已消失或不可读的工件保持可见。异步冷读取结束后，期间已附加的 Session 会改用实时日志生成摘要。`updatedAt` 依次采用实时折叠、小工件精确折叠或 projection cache，缺失时回退到 `createdAt`；拾起边界及其他写入都不会提升 Session 排序。
+`session.models` 把当前 `ModelSelection` 与按提供方分组的咨询模型分开报告，`session.selectModel` 通过共享的 `agent-default-model` settings 分节把已接受的切换保存为部署默认值——指向不可用提供方的默认值仍会作为 `current` 送到选择器，而不是被静默替换。每次访问都先解析进程内选择，再读会话最新的 `request/header`，最后使用部署默认值。日志中标记为适配器默认值的推理强度不会进入恢复后的选择，因此下一次解析不会把它提升为显式选择，也不会记录虚假 header 变更。`agentPreset.list` 暴露部署的 preset 名单，每行带 `trust`，preset 无法组合会话时带 `broken` 原因；`agentPreset.select` 替换空白会话的组合，一旦跑过一轮即被拒绝。`skill.list` 为 composer 菜单提供每个 skill 的 `modelInvocable` 标志，`command.execute` 以纯准入语义运行斜杠命令，其结局由落账的 `command/run`／`command/done` 事件对承载。`settings.*`、`credentials.*` 与 `llm.*` 领域是配置页协议：`settings.describe` 返回每个 namespace 的 schema 与脱敏后的分层值，`settings.mutate` 是持有脱敏视图的客户端的删除路径，secret 绝不搭乘任何响应，`llm.discoverModels` 询问页面尚在起草的提供方端点而不写任何东西。
 
-`session.search` 是以 `session.list` 所列会话为范围的有界内容搜索投影。网关向可选的 `ctx.sessionQuery` 服务请求全局排序后的当前内容视图中的 user、assistant 和 steering 匹配项，并持续消费该结果流，直到获得至多 20 个可见会话／snippet 对及一个前瞻项；返回前仍会依据从列表推导的授权集合重新校验每个命中。提供方分页初始请求 20 个命中；如果第一页请求因这一上限被拒绝，网关会依次探测 10、5、2、1，并在续传和陈旧世代重启中沿用探测所得的页面大小。返回的 snippet 最多包含 240 个 Unicode 码点，响应 schema 则会在每个客户端边界独立强制执行该上限。将授权集合保留在宿主内存中，可在不削弱可见性或排序的前提下避开有效大型语料库的 SQLite 变量上限。
+### 配置
 
-陈旧的续传会丢弃该提供方尝试中的所有部分结果、去重条目和游标，然后依据最初从列表推导的可见性快照从第一页重新开始，但不会丢弃探测所得的提供方页面大小。上限探测与陈旧重试共用最多 100 次提供方调用的限制（因此最多检查 2,000 个命中）；如果某页命中数超过其请求的上限、续传游标重复，或用尽该调用预算后结果流仍未耗尽，都会直接返回 `internal` 业务错误，不返回部分结果。载体请求信号可取消持久化列表枚举、冷会话摘要收集和每一次搜索调用；即使同时收到上限拒绝或陈旧拒绝，也以取消为准。部署若未挂载该服务，或索引／查询故障无法恢复，也会返回 `internal` 业务错误，以便客户端保留仅基于元数据的匹配项。
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `nativeOpen` | 平台探测 | 部署能否把路径交给原生桌面打开器 |
+| `sessionExportCompressionLevel` | `6` | 每个会话日志 ZIP 条目的 DEFLATE 级别，0–9 |
 
-目录选择委托给组合的 `ctx.directoryPicker` 后端（[目录选择 seam](../directory-picker/README.zh.md)）；调用组合能力 kind 之外的方法会以 `directory-picker-unavailable` 失败（客户端不需要广播——组合的选择器包自己的 client half 渲染匹配的交互）。在 `native` 下，`host.pickDirectory` 打开一个原生选择器并返回选中路径（取消为 `null`）；该方法需等待用户完成操作，不使用默认的 30 秒一元调用超时，而调用方与连接的中止仍会传播至原生进程。在 `browse` 下，`host.listDirectory` 返回一个按名称排序的目录层级，携带面包屑祖先链、`home` 锚点与宿主判定的 `hidden` 标志（不带路径即家目录），`host.createDirectory` 创建一个经校验的子段；后端的类型化失败 1:1 映射为 `directory-unreadable`／`directory-exists`／`directory-create-failed` 错误码。浏览器载体的前缀级信任栅栏（dsh-client-connection）像覆盖其他所有 `/api` 请求一样覆盖上述全部方法。
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-host-apiproxy)是每个受支持字段及其 JSDoc 的穷尽式真源。
 
-`host.openPath` 会用操作系统的默认应用打开一个文件系统路径（macOS 为 `open`，Windows 为 `Invoke-Item`，桌面 Linux 为 `xdg-open`）。对于 `.html`、`.htm`、`.xhtml` 与 `.svg`，macOS 和桌面 Linux 会优先使用能够确定的默认浏览器；无法确定时回退到上述应用交接。WSL 会通过 `wslpath -w` 转换每个 Linux 路径，并将所得 Windows/UNC 路径交给 Windows `Invoke-Item`，浏览器可渲染的文档也不例外，而非假定存在 Linux 桌面文件关联。`host.describe.home` 是宿主账户的家目录。Web 客户端用它把 POSIX 家目录路径显示为 `~`；Windows 值仍会上报，但不会缩写。`host.describe.canOpenPath` 会宣告这次交接能否抵达用户可见的桌面：网关显式配置的 `nativeOpen` 优先，注入的 opener 按定义可用，否则平台检测接受 macOS、Windows、WSL 或带 display 的 Linux，并拒绝 headless／容器 Linux。浏览器载体对其施加与每个 Host API 方法相同的 Host/Origin 校验和签名 cookie 认证；客户端会组合能力事实后再呈现原生操作。
+-----
 
-`agentPreset.list` 领域向浏览器暴露部署的 preset 名单，使其在开启会话时能够提供选择；每一行携带它的 `trust`（`user` preset 的权限恰好等于它所引用的插件）、它是否为当前默认值，以及——当该 preset 无法组装会话时——一条 `broken` 原因：损坏的目录仍占着它的 id，界面必须能展示并删除它，而不是把它端出来然后在会话启动时失败。未组装任何 preset 的部署返回空名单而非错误，因为共用宿主组装本身就是一种有效部署。`agentPreset.select` 用另一个 preset 重组某个会话的 agent，且仅在会话空白时允许：一旦跑过任何轮次，那段历史就是在该 preset 的工具下产生的，替换会留下无法执行的已记录的工具调用，此时返回 `agent-preset-locked`。agent 与会话都不销毁——只替换组装，且替换失败会恢复原来的组装。
+<a id="understand-the-implementation"></a>
+## 理解实现
 
-`agentPreset.read`、`copy`、`openDocument` 与 `remove` 负责管理组装本身。`read` 返回文本连同它的 `trust`，供只读查看器使用。创作只有复制一种写入：`copy` 接收 `{ from, agentPreset, name? }`——两个由 Host 对照自身根目录解析的 id 加一个可选显示名——并整目录复制来源，因此组装文本不经过传输层，副本与其来源同等可加载；不可约束或已被占用的 id 回答 `agent-preset-invalid`，`remove` 对随附 preset 回答 `agent-preset-read-only`。`openDocument` 把一个本地创作 preset 的**目录**交给平台打开器——请求只携带 id、绝不携带路径，因此没有任何浏览器载荷能选中任意文件系统目标；部署没有原生打开器时回答 `{ opened: false, path }` 供界面以文本展示，随附 preset 与 `remove` 一样被拒绝，而网关的 `nativeOpen` 配置可在平台探测（`canOpenNativePath`）失真处钉死该能力。[`dsh-client-connection`](../../client/connection/README.zh.md) 用与 `list`、`select` 及完整 Host API 相同的浏览器会话认证这些方法。组装仍指明一个会话所运行的插件，因此读取它是侦察，而 copy/remove/openDocument 管理名单并驱动宿主桌面。`list` 报告两个不含路径的能力标志：`authorable`，即部署是否配置了可供复制新 preset 的根目录；`hasDocument`，即 `openDocument` 会原生打开、还是回答一个路径。

-`command.*` 与 `skill.*` 领域向客户端暴露宿主命令注册表和 skill（技能）目录。每个方法都通过 `sessionId` 寻址一个会话的 Agent（被服务的会话必有 Agent；`command.*` 经由与 `session.*` 相同的路径恢复冷会话，而 `skill.list` 从会话头解析项目根目录，不触碰 Agent 注册表）。`skill.list` 服务于 composer 的菜单：它返回每一个用户可调用的 skill 及其 `modelInvocable` 标志，让菜单能够标出仅限用户（`disable-model-invocation`）的条目——斜杠手势是这类条目唯一的调用路径。列表是 skill 领域唯一的 RPC——调用本身就是一次普通的 `session.prompt`，`dsh-tool-skill` 会在 pre-step 边界识别其中以空白为界的 `/name` token，并以注入的 `<skill_content>` 上下文作答，因此所有入口（Web、TUI 与 ACP（Agent Client Protocol））共享同一条确定性路径，手动键入的文本也走该路径，且没有专设的调用协议。`command.execute` 在宿主侧运行一条斜杠命令行，语义为纯准入：响应报告该行是否解析到处理器，并在解析到时回带铸造的生命周期 `commandId`（将本次确认与流节点关联）；结局经由持久落账并在 mux 流广播的 `command/run`/`command/done` 生命周期事件对承载。命令处理器运行超过 30 秒的传输健康时限仍属正常，因此 `command.execute` 仅携带调用方／连接取消信号；该信号可取消正在运行的处理器。`commands/change` 搭乘转发事件帧作为注册表级目录失效信号：客户端重新拉取 `command.list` 而不是做差分。转发的 `agent-preset/selected` 是它按会话粒度的对应物，由落账的选择提交点发出：重组空会话的 agent 只是重新挂接其 scope，不产生任何注册，因此该会话组成所决定的两份目录（`command.list`、`skill.list`）都会失效，却没有任何注册表变化来宣告它。
+### 设计理念
 
-`settings.*`、`credentials.*` 与 `llm.*` 领域是配置页协议。settings 领域服务于每一个已注册 namespace：在本仓库之外分发的插件只要注册自己的分节即可变得可从浏览器配置，无需改动这里；本代理不自设边界——没有任何注册应答的名字会折叠为 seam 自己的 `settings-rejected`。由哪个界面渲染某个 namespace 是浏览器的决定（插件配置页按 namespace 为其卡片编键），从不由本代理决定。`settings.describe` 为每个 namespace 提供其序列化 schemastery schema、脱敏后的分层值（resolved/`base`/`user`——字段出现在 `user` 中即标记其被用户覆盖）、`secrets` 槽位列表、该分节的 `revision`，以及布尔型 `hasDocument` 能力标志。浏览器不会收到 Host 路径：无路径参数的 `settings.openDocument` 会请求提供方准备文档，再把由 Host 解析出的结果交给原生打开器，因此任何浏览器载荷都无法选择任意文件系统目标。`settings.update`/`settings.replace` 写入用户层；`settings.mutate` 则在已存分节上施加路径 op（`set`/`unset`），这是持有脱敏视图的客户端的删除路径——据此重建分节再整体替换，会删掉协议从未回传过的那些机密。任何写入都可携带 `expectedRevision`；陈旧的期望值会以 `settings-conflict` 连同两个 revision 作答，而不是覆盖先落地的那个写方，其余每种 seam 拒绝则折叠为 `settings-rejected`。secret 角色的值绝不在任何一层搭乘任何响应；secret 只沿一个方向跨越协议——在 `update`/`mutate` 载荷或 `credentials.set` 之内。`credentials.describe` 返回不含值的视图（`configured`/`source`/`writable`），`credentials.set`/`credentials.unset` 则把被遮蔽引用的拒绝映射为 `credential-rejected`。`llm.providers` 把可配置提供方目录与存活路由合并（休眠条目携带 `active: false`；未声明的存活路由追加在后，不带 settings 地址），`llm.models` 则是与会话无关的目录。`llm.discoverModels` 询问页面尚在起草的提供方端点：`settingsNs` 选出懂得读取该列表的适配器家族，端点、协议与密钥则来自表单而非存储。它什么都不写——回复是候选，只有随后的 `settings.mutate` 才决定路由服务什么——因此其 `apiKey` 是 secret 可以搭乘的第三个载荷（另两个是 `settings.update`/`mutate` 与 `credentials.set`），且绝不被存储或回显。host 从不存储或回传它；与另两者一样，它确实会搭乘客户端的出站信封，`subscribeEnvelopes()` 的观察者能看到——为该 tap 做脱敏是整个配置面的改动，而非本方法一家的事。每一种拒绝（无人服务的 namespace、没有可读列表的协议、不可达端点、被拒凭据）都折叠为 `model-discovery-failed`，其消息是适配器自己的文本，details 点名被询问的端点，绝不点名所提供的凭据。失效通知让每个面无需轮询即保持收敛。`settings/document-updated` 与 `credentials/reference-updated` 搭乘原样转发事件帧（见下），因此解析值未变的原始设置变更同样能到达客户端，凭据失效通知也仍然只带引用名、绝不带值。`llm/adapters-updated` 与 `settings/document-updated` 一并原样转发；具体模型消费方直接订阅这两个 owner 事件，因为拓扑提交和设置文档都能独立改变其目录。Connection 用与每个 Host API 方法相同的浏览器会话认证整个配置面，包括读取与原生操作。未装 settings 或凭据提供方的组合会以指名缺失插件、包含解决建议的 `internal` 错误应答这些领域。
+本包建立在一个分离之上：API 约定与通道无关，物理传输只是围绕它的载体。协议消息构成一个二元可辨识联合——`ClientRequest`（POST `/api/<method>` 的请求体）与 `ServerResponse`（该 POST 的响应体）——与物理通道解耦。响应始终回显对应请求的 `rpcId`，绝不签发新值。业务错误由 `RpcResult` 的错误分支承载，其 `RpcErrorDetailsMap` 封闭错误码集合；HTTP 状态只表达载体层结果。分层与协议决策记录在 [GUI 分层与 RPC 协议 RFC](../../../.agents/notes/implemented/architecture/2026-07-19-gui-layering-and-rpc-protocol.zh.md) 中。

-`AbstractApiClient` 持有全部协议不变量：签发 rpcId、包装／解包信封、Zod 解析、SSE 帧解码、一元请求超时，以及按微任务批处理的信封观测（`subscribeEnvelopes`）；平台子类只提供 `doFetch` 传输环节。`InProcessApiClient` 以 `toFetchHandler(api)` 为基础，仍是同构接点：它运行完整的协议序列化与校验路径而不经过网络，供需要该路径的调用方和载体测试使用。产品的 `dsh --profile headless` 是直连 core 的入口，不挂载本包。

+
+### 请求流
+
+请求进入载体，载体分两层解析信封与业务载荷、按方法分发，并返回回显请求 `rpcId` 的响应。服务器推送——会话与工作区 follow 流——搭乘 API Gateway 的 `/api/remote.mux` WebSocket，投递 `opened` 及之后无间隙的 `event` 帧，由客户端解码。一元请求携带载体的中止信号，因此调用方／连接的取消会传播到底层工作。
+
+### 网关拥有什么
+
+网关是协议约定外加一层对别处所拥有服务的宿主侧投影：它不发出任何 cordis 事件，它所投影的会话／agent 事件流由各自所属包的伴生插件断言。载体不持有其他领域的知识——每个投影值在注册表内部已经过其单元自己的 schema。

 English | [中文](README.zh.md)
 
-The **adaptive chooser** of the [directory-picker seam](../directory-picker/README.md): a node-half-only plugin that resolves the host's situation once at boot and mounts the matching dual-face backend — [`-native`](../directory-picker-native/README.md) or [`-browse`](../directory-picker-browse/README.md) — as a real Loader entry in the in-memory root tree (never persisted to a config file; the root tree's `write()` is a no-op). Because the backend arrives as an ordinary entry, its browser half is discovered by the client module table exactly as a config-row's would be, so the seam's one-row-swaps-both-faces invariant holds for the resolved choice. Unloading the chooser removes the entry again, unloading both faces with it.
+## Summary
 
-Resolution is one pure boot-time sample (`resolveDirectoryPickerBackend`), exported for reuse. `native` requires every signal that the operator can see the host display and the native backend can serve it: a loopback-only bind (read from the injected `webServer`; an all-interfaces bind admits remote browsers no OS chooser can reach), no SSH launch (`SSH_CONNECTION`/`SSH_TTY` unset or blank — under SSH port-forwarding the chooser would open on the unattended server), and a servable display session — assumed on darwin/win32; on linux `DISPLAY`/`WAYLAND_DISPLAY` plus a zenity or kdialog binary on `PATH` (the probe is one more boot-time fact); never on any other platform, since the native backend drives exactly darwin/win32/linux. Anything ambiguous resolves to `browse`, which works everywhere. The sample happens exactly once per boot so the mounted capability stays stable for the service lifetime, as the seam requires. Pinning an interaction is not a config field here — compose the `-native` or `-browse` row directly instead of this one, the seam's documented swap point; mounting the chooser **and** a backend row together fails loud (duplicate `directoryPicker` service, duplicate client flow in the `single` holes).
+`dsh-host-directory-picker-auto` picks the right directory-picking interaction for every boot: it resolves the host's situation once at boot and mounts the matching backend — [native](../directory-picker-native/README.md) or [browse](../directory-picker-browse/README.md) — together with its browser half, as real Loader entries in the in-memory root tree. The resolution is one pure boot-time sample: `native` requires a loopback-only bind, a non-SSH launch, and a servable display session; anything ambiguous resolves to `browse`, which works everywhere. Pinning an interaction means composing that backend directly. The mounted capability stays stable for the service lifetime, as the seam requires.

+## Use this package
+
+Compose this plugin instead of a concrete backend when the same composition must serve hosts that differ: local workstation sessions where a native chooser works, and remote or headless sessions where only the in-app browser works. The chooser inspects the host once at boot and mounts the matching interaction.
+
+### How the choice is made
+
+`native` requires every signal that the operator can see the host display and the native backend can serve it: a loopback-only bind (read from the injected `webServer`; an all-interfaces bind admits remote browsers no OS chooser can reach), no SSH launch (`SSH_CONNECTION`/`SSH_TTY` unset or blank), and a servable display session — assumed on darwin and win32; on linux, `DISPLAY`/`WAYLAND_DISPLAY` plus a zenity or kdialog binary on `PATH`; never on any other platform. Anything ambiguous resolves to `browse`, which works everywhere.
+
+### What you get
+
+The resolved interaction arrives as an ordinary Loader entry: the backend registers `ctx.directoryPicker`, and its browser half is discovered by the client module table exactly as a config row's would be, so the seam's one-row-swaps-both-faces invariant holds. Unloading the chooser removes the entry, unloading both faces with it. The sample happens exactly once per boot, so the mounted capability stays stable for the service lifetime.
+
+### Pinning an interaction
+
+Pinning is not a config field here: compose the `-native` or `-browse` row directly instead of this one — that is the seam's documented swap point. Mounting the chooser and a backend row together fails loud (duplicate `directoryPicker` service, duplicate client flow in the `single` holes).
+
+### Observable failures
+
+A wrong `native` choice degrades to the backend's existing retryable failure dialog rather than a broken composition; composing `-browse` directly selects the safe interaction for deployments whose situation the probe cannot prove.

+
+### Design concept
+
+The chooser is a pure decision plus a mount: `resolveDirectoryPickerBackend` samples host facts once at boot and returns a backend kind, and `apply` mounts the matching backend and surface packages as real Loader entries in the in-memory root tree — never persisted to a config file, because the root tree's `write()` is a no-op. The effect's disposer removes both entries and joins their fibers' teardown, so unloading returns only after both faces of the mounted interaction quiesced.

 ## Known Limitations and Deferred Work
 
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define when the boot-time sample can misjudge the host. They are current package constraints, not a task backlog.
+
 - **Detection infers operator location from launch context, which no launch-side signal can prove** — a tmux session detached from its SSH launch loses the `SSH_*` markers; a Darwin process outside an Aqua session still counts as displayed; and a workstation-local launch later reached through `ssh -L` arrives from `127.0.0.1`, resolves `native`, and opens the chooser on the unattended workstation. A wrong `native` choice degrades to the backend's existing retryable failure dialog, and composing `-browse` directly selects the safe interaction for such deployments.
 - **The Linux chooser probe reads `PATH` only** — a zenity/kdialog reachable some other way (shell alias, non-PATH install) still resolves `browse`; installing either binary on `PATH` restores `native` eligibility at the next boot.
-- **Boot-time only** — one resolution serves every client of the boot; per-connection adaptivity (native for a local browser, browse for a remote one, same server) would need a per-client capability and the wire advertisement the seam deliberately deleted, and waits for a deployment that serves both at once.

+## 使用本包
+
+当同一份组合必须服务处境不同的宿主时，用本插件代替具体的后端：本地工作站会话里原生选择器可用，远程或无头会话里只有应用内浏览器可用。选择器在启动时检查一次宿主，并挂载匹配的交互。
+
+### 选择是如何作出的
+
+`native` 要求「操作者看得到宿主屏幕、且原生后端能服务它」的全部信号：仅回环的绑定（从注入的 `webServer` 读取；全网卡绑定会接入任何 OS 选择器都触及不到的远程浏览器）；非 SSH 启动（`SSH_CONNECTION`／`SSH_TTY` 未设置或为空）；以及可服务的显示会话——darwin 与 win32 上视为存在；linux 上要求 `DISPLAY`／`WAYLAND_DISPLAY`，外加 `PATH` 上有 zenity 或 kdialog 二进制；其余任何平台上都不成立。任何含糊情形都判定为处处可用的 `browse`。
+
+### 你会得到什么
+
+判定出的交互以普通 Loader 条目的形式到达：后端注册 `ctx.directoryPicker`，其 browser 半侧被 client 模块表发现的方式与配置行完全相同，因此 seam 的「一行同时换两面」不变式依然成立。卸载该选择器会移除该条目，连同两面一起卸载。采样每次启动恰好发生一次，因此挂载的能力在服务生命周期内保持稳定。
+
+### 固定某种交互
+
+固定交互在这里不是配置字段：直接组合 `-native` 或 `-browse` 行来替代本行——那才是 seam 文档化的切换点。同时挂载选择器**和**某个后端行会明确报错（重复的 `directoryPicker` 服务、`single` 类 slot 中的重复 client 流程）。
+
+### 可观察的失败
+
+错误的 `native` 选择会退化为后端既有的可重试失败对话框，而不是坏掉的组合；对探查无法证明其处境的部署，直接组合 `-browse` 即选择安全的交互。

+### 设计理念
+
+选择器是一次纯决策加一次挂载：`resolveDirectoryPickerBackend` 在启动时采样宿主事实并返回一个后端类型，`apply` 把匹配的后端与界面包作为真实 Loader 条目挂进内存根树——绝不持久化到配置文件，因为根树的 `write()` 是 no-op。该 effect 的 disposer 会移除两个条目并汇合其 fiber 的拆除，因此卸载只在所挂载交互的两面（及其依赖方）完全停稳后返回。

 # @deepseek-ai/dsh-host-directory-picker-browse
 
 English | [中文](README.zh.md)
 
-The **in-app browsing backend** of the [directory-picker seam](../directory-picker/README.md): `BrowseDirectoryPicker` registers `ctx.directoryPicker` with the `browse` capability — one-level directory listing and child-directory creation over Node's stdlib, which already carries the per-OS adaptation. Nothing renders on the host display, so this backend serves remote clients the native backend cannot.
+## Summary
 
-Behavior facts: listings return **directories only**, name-sorted, with symlinks-to-directories followed (broken/cyclic links skipped — the probe `stat` failing means "not enterable") and a host-owned `hidden` flag (POSIX dot convention) left for the client to act on; `crumbs` is the root-to-target ancestor chain, the root crumb labeled by its full path (`/`, `C:\`); an absent `list` path means the host account's home directory. `createDirectory` is non-recursive (a missing parent is a real failure, not a level to invent) and validates the name as a single non-blank segment even when called directly, mirroring the wire schema's fence. Both primitives reject an explicit path that is not fully qualified — relative forms, and on Windows the rooted drive-less forms (`\foo`, `/foo`) and incomplete UNC prefixes (`\\`, `\\server`) that `isAbsolute` accepts — with `directory-unreadable`/`directory-create-failed`, instead of letting `resolve` rebase it under the host process cwd or current drive. One `list` call returns at most `maxEntries` rows (config, default 1000 — the bound GitHub's web UI applies to directory listings), and the level streams through a bounded window so memory stays O(maxEntries) no matter how many children the directory holds: a cut level keeps the name-sorted head, counts hidden rows against the bound, probes only windowed candidates, and reports `truncated: true` so the client can say the level is incomplete (a windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated); window insertion is binary with an O(1) full-window tail rejection, and `list` threads the caller's `AbortSignal` so a disconnect or timeout stops the scan instead of letting it outlive the caller. Failures throw the seam's typed `DirectoryPickerError`. Policy rationale: [the directory-picker capability seam Agent Note](../../../.agents/notes/implemented/architecture/2026-07-28-directory-picker-capability-seam.md).
+Users who cannot reach an OS chooser still pick a workspace directory through `dsh-host-directory-picker-browse`: it provides one-level directory listing and child-directory creation over Node's standard library, and nothing renders on the host display — so it serves the remote clients the native backend cannot reach. Listings return directories only, name-sorted, with symlink-to-directory following and a host-owned `hidden` flag; creation is non-recursive and validates a single path segment. One composition row also fills the workspace flow's directory holes with the in-app **Select Workspace Directory** dialog.
 
-**Dual-face package**: the browser half (`./client`) fills [ui-workspace's](../../client/ui-workspace/README.md) two directory-flow holes with the in-app **Select Workspace Directory** dialog (figma `Harness` 813-23126 family — Miller two-column view whose navigations land selection-anchored and quiet: the previous view keeps rendering while a crumb jump or a submitted path is scanned (a "Loading…" pill floats over it only once the scan outlives a 300ms silence window, never shifting the columns), then target and parent legs land as one two-pane frame with the target re-selected as its actual parent-level entry — so stepping back never collapses and no intermediate frame flashes (a parent leg outliving its 200ms wait bound lands the target alone and upgrades in place; a failed or truncated parent leg keeps the single-pane landing; the display root keeps the single wide level); breadcrumb with a click-to-edit path zone, advertised by the pencil glyph at the bar's right edge and lighting the whole bar — the editor's own box — on hover, whose editor seeds a trailing separator and then keeps the panes under the draft: the final segment prefix-filters the LAST pane while that pane lists the level the directory part names (case-insensitively, over the listed — possibly truncated — rows only; a tail nobody matches releases the filter instead of emptying the pane), while any other directory part is scanned after a 250ms rest and lands like any other navigation — selection-anchored, two-pane away from the display root, both legs waited out so one keystroke moves the view once — so typing deeper descends and erasing segments walks back up without leaving the editor; the pane arity is the invariant, the last pane always listing the level the path names with its parent beside it (only that level's own tail costs no scan, and only a display root lists alone), and a level still answers the text that produced it after the Host resolved it (`..` segments, Windows forward slashes) — a speculative scan is silent when it fails, and Enter still navigates by the exact text, owning the view until it lands; the editor cancels on Escape or when focus leaves the dialog card (window/tab switches and in-card focus moves keep the draft), and panes the draft walked to stay where the walk ended — the crumbs name that level and Open's fallback target follows them, so cancelling closes the editor rather than rewinding the walk; a fixed-label show-hidden footer toggle over the host's `hidden` flags, with a dot-led typed prefix revealing its matches and the current selection exempt from every filter; nested New-folder dialog), driving `host.listDirectory`/`host.createDirectory` and registering its own locale namespace (`directory-browser`, zh default / en). Both directory-flow declarations must be live before either contribution installs. One cordis.yml row therefore composes both sides of the browse interaction; the client carries no capability-kind branching, and mounting a second flow package fails at load (the holes are `single` kind).

+## Use this package
+
+Compose this backend when a workspace directory must be chosen without an OS chooser — remote browsers, SSH-forwarded sessions, or unattended hosts. The workspace flow drives `host.listDirectory` and `host.createDirectory`; both primitives answer from the host filesystem.
+
+### Listing a directory
+
+`list(path?)` returns one directory level: name-sorted child directories with their absolute paths, a `hidden` flag (dot-prefixed on POSIX), a `home` anchor, and `crumbs` — the root-to-target ancestor chain where every crumb is a jump target and the root is labeled by its full path. An absent path lists the host account's home directory. One call returns at most `maxEntries` rows (config, default 1,000 — the bound GitHub's web UI applies to directory listings), and a cut level reports `truncated: true` so the client can say the level is incomplete. Symlinks to directories are followed; broken and cyclic links are skipped.
+
+### Creating a directory
+
+`createDirectory(path, name)` creates one child directory under an existing parent. It is non-recursive — a missing parent is a real failure, not a level to invent — and rejects anything but a single non-blank path segment (`name` must not contain separators and must not be `.` or `..`).
+
+### Observable failures
+
+Both primitives refuse a path that is not fully qualified — relative forms, and on Windows the rooted drive-less forms (`\foo`, `/foo`) and incomplete UNC prefixes that `isAbsolute` accepts — with `directory-unreadable` or `directory-create-failed`, instead of resolving it under the host process working directory. Creation of an existing child answers `directory-exists`. A caller's `AbortSignal` stops an in-flight scan, so a disconnect or timeout does not leave the scan outliving the caller.
+
+### Configuration
+
+| Field | Default | Meaning |
+|---|---|---|
+| `maxEntries` | `1,000` | Complete-result bound of one listing level; hidden rows count toward it |

+<summary>Implementation internals — click to expand</summary>
+
+### Design concept
+
+The backend streams one directory level through a bounded name-sorted window so memory stays O(maxEntries) no matter how many children the directory holds: a cut level keeps the name-sorted head, hidden rows count against the bound, only windowed candidates are probed, and the level reports `truncated: true`. Window insertion is binary with an O(1) full-window tail rejection, so an oversized level costs O(1) per candidate past the head instead of a window scan.
+
+### The fully-qualified fence
+
+`fullyQualified` rejects any path that does not name one fixed filesystem location regardless of process state: POSIX-absolute on POSIX; on Windows only drive-qualified (`C:\…`) or complete UNC (`\\server\share…`) forms. Rooted drive-less forms and incomplete UNC prefixes pass `isAbsolute` yet still resolve against the process's current drive, so the backend refuses them rather than rebasing a wire value.
+
+### Abort and probing
+
+Every filesystem await races the caller's signal (`raceAbort`), so a stalled network filesystem cannot keep a departed caller's request alive; an abandoned read's late settlement is swallowed. Symlink enterability is decided by a `stat` probe — failure means not enterable — and a windowed broken symlink is not backfilled from beyond the window, because an eviction already marked the level truncated.

-[目录选择 seam](../directory-picker/README.zh.md) 的**应用内浏览后端**：`BrowseDirectoryPicker` 以 `browse` 能力注册 `ctx.directoryPicker`——基于 Node 标准库（跨 OS 适配本就由它承担）提供单层目录列举与子目录创建。宿主屏幕上不渲染任何东西，因此该后端能服务原生后端无法触及的远程客户端。
+## 概述
 
-行为事实：列举**只返回目录**、按名称排序，指向目录的符号链接会被跟随（断链／循环链接被跳过——探测 `stat` 失败即「不可进入」），并携带宿主判定的 `hidden` 标志（POSIX 点前缀约定），展示决策留给客户端；`crumbs` 是从根到目标的祖先链，根 crumb 以完整路径标注（`/`、`C:\`）；`list` 不带路径即列举宿主账户的家目录。`createDirectory` 不递归（父目录缺失是真实失败，不是要补造的层级），且即便被直接调用也把名称校验为单个非空白段，与协议 schema 的栅栏一致。两个原语都拒绝非完全限定的显式路径——相对形态，以及 Windows 上 `isAbsolute` 会放行的无盘符有根形态（`\foo`、`/foo`）与不完整的 UNC 前缀（`\\`、`\\server`）——报 `directory-unreadable`／`directory-create-failed`，而不是任由 `resolve` 把它重定位到宿主进程 cwd 或当前盘符之下。单次 `list` 至多返回 `maxEntries` 行（配置项，默认 1000——GitHub 网页端对目录列举采用的同一上限），且层级以流式方式经过一个有界窗口，无论目录有多少子项内存都保持 O(maxEntries)：被截断的层级保留按名排序的头部、隐藏行计入上限、只探测窗口内候选，并报告 `truncated: true`，供客户端提示层级不完整（窗口内的断链符号链接不会从窗口外回填——发生过驱逐本身已把层级标记为截断）；窗口插入为二分查找、满窗尾部单次比较即拒绝，且 `list` 透传调用方的 `AbortSignal`，断连或超时会停止扫描而不是让它在调用方离开后继续。失败抛出 seam 的类型化 `DirectoryPickerError`。策略依据：[目录选择能力 seam Agent Note](../../../.agents/notes/implemented/architecture/2026-07-28-directory-picker-capability-seam.zh.md)。
+无法触达 OS 选择器的用户仍能通过 `dsh-host-directory-picker-browse` 选择工作区目录：它基于 Node 标准库提供单层目录列举与子目录创建，宿主屏幕上不渲染任何东西——因此它能服务原生后端无法触及的远程客户端。列举只返回目录、按名称排序，跟随指向目录的符号链接，并携带宿主判定的 `hidden` 标志；创建不递归，且把名称校验为单个路径段。一行组合配置还会用应用内**选择工作区目录**对话框填满工作区流程的目录扩展位。
 
-**双面包**：浏览器侧（`./client`）以应用内 **选择工作区目录** 对话框（figma `Harness` 813-23126 家族——Miller 双列视图，其导航以选中项为锚、安静落地：扫描 crumb 跳转或提交的路径期间，先前视图持续渲染（「Loading…」胶囊仅在扫描超出 300ms 静默窗口后才浮于其上，绝不挪动各列），随后目标与父层级两程以单个双栏帧落地，目标被重新选中为其在父层级中的实际条目——因此后退绝不塌缩，也没有中间帧闪现（父层级这一程超出其 200ms 等待上限时，目标单独落地，随后就地升级；父层级这一程失败或被截断时保持单栏落地；展示根保持单个宽层级）；带点击即编辑路径区的面包屑，该区由栏右端的铅笔图标点明，悬停时整条栏——也就是编辑器自身的那只框——亮起，其编辑器预填尾随分隔符，随后让下方各栏跟随草稿：当最后一栏正是目录部分所指的层级时，末段对这一栏做前缀过滤（不区分大小写，且仅作用于已列出、可能被截断的行；无一匹配的末段会解除过滤，而不是把该栏清空），而其余任何目录部分都会在停顿 250ms 后被扫描，并像其他任何一次导航那样落地——以选中项为锚，在展示根之外即双栏，且两程都等齐，于是一次按键只让视图移动一次——继续键入即下潜、删掉末段即上退，全程不必离开编辑器；分栏个数是这里的不变量：最后一栏永远是路径所指的那一层，其上一层在它旁边（只有这一层自己的末段不触发扫描，也只有展示根会独占一栏），而宿主规范化过路径之后（`..` 段、Windows 的正斜杠），该层级仍然应答产生它的那段文本——推测性扫描失败时保持沉默，而 Enter 仍按确切文本导航，并在落地前独占视图；编辑器按 Escape 或焦点离开对话框卡片即取消（窗口／标签页切换与卡片内焦点移动保留草稿），而草稿走到的层级会留在原地——面包屑指明该层级、Open 的兜底目标随之而动，因此取消只是关闭编辑器，并不回退这段行走；基于宿主 `hidden` 标志、标签固定的「显示隐藏」footer 开关，键入以点开头的前缀会显出其匹配项，且当前选中项不受任何过滤影响；嵌套新建文件夹对话框）填入 [ui-workspace](../../client/ui-workspace/README.zh.md) 的两个目录流程扩展位，驱动 `host.listDirectory`／`host.createDirectory`，并注册自己的 locale 命名空间（`directory-browser`，zh 默认／en）。两个目录流程声明必须同时处于 live 状态，任一贡献才会安装。因此一行 cordis.yml 同时组合浏览交互的两侧；client 侧不含任何能力 kind 分支，挂载第二个流程包会在加载期失败（洞为 `single` kind）。

+`list(path?)` 返回一个目录层级：按名称排序的子目录及其绝对路径、`hidden` 标志（POSIX 上为点前缀）、`home` 锚点，以及 `crumbs`——从根到目标的祖先链，其中每个 crumb 都是跳转目标，根以完整路径标注。不带路径时列举宿主账户的家目录。单次调用至多返回 `maxEntries` 行（配置项，默认 1,000——GitHub 网页端对目录列举采用的同一上限），被截断的层级会报告 `truncated: true`，供客户端提示层级不完整。指向目录的符号链接会被跟随；断链与循环链接被跳过。
+
+### 创建目录
+
+`createDirectory(path, name)` 在既有父目录下创建一个子目录。它不递归——父目录缺失是真实失败，不是要补造的层级——并且拒绝任何非单个非空白路径段的内容（`name` 不得包含分隔符，也不得为 `.` 或 `..`）。
+
+### 可观察的失败
+
+两个原语都拒绝非完全限定的路径——相对形态，以及 Windows 上 `isAbsolute` 会放行的无盘符有根形态（`\foo`、`/foo`）与不完整的 UNC 前缀——报 `directory-unreadable` 或 `directory-create-failed`，而不是把它解析到宿主进程工作目录之下。创建已存在的子目录回答 `directory-exists`。调用方的 `AbortSignal` 会停止进行中的扫描，因此断连或超时不会让扫描比调用方活得更久。
+
+### 配置

+| 字段 | 默认值 | 含义 |

+
+### 设计理念
+
+后端把单个目录层级流式送入一个有界、按名排序的窗口，因此无论目录有多少子项，内存都保持 O(maxEntries)：被截断的层级保留按名排序的头部、隐藏行计入上限、只探测窗口内候选，并报告 `truncated: true`。窗口插入为二分查找、满窗尾部单次比较即拒绝，因此超大型层级在头部之后的每个候选都只需 O(1)，而不是窗口扫描。
+
+### 完全限定栅栏
+
+`fullyQualified` 拒绝任何不指向一个与进程状态无关的固定文件系统位置的路径：POSIX 上要求 POSIX 绝对路径；Windows 上只接受盘符限定（`C:\…`）或完整 UNC（`\\server\share…`）形态。无盘符有根形态与不完整 UNC 前缀能通过 `isAbsolute`，却仍会解析到进程的当前盘符，因此后端拒绝它们，而不是重定位一个 wire 值。
+
+### 中止与探测
+
+每个文件系统 await 都与调用方的信号竞争（`raceAbort`），因此停滞的网络文件系统不能让已离开的调用方请求继续存活；被弃读的迟到结算会被吞掉。符号链接的可进入性由 `stat` 探测决定——失败即不可进入——窗口内的断链符号链接不会从窗口外回填，因为发生过驱逐本身已把层级标记为截断。

 # @deepseek-ai/dsh-host-directory-picker-native
 
 English | [中文](README.zh.md)
 
-The **native-OS-chooser backend** of the [directory-picker seam](../directory-picker/README.md): `NativeDirectoryPicker` registers `ctx.directoryPicker` with the `native` capability, whose `pick(signal)` opens one native chooser per call and resolves the chosen absolute path (`null` on cancel). Platform tools run without a shell: `osascript` on macOS and Zenity with a KDialog fallback on Linux; the caller's abort terminates the native process. Windows opens the modern `IFileOpenDialog` in a spawned child process — a koffi-driven COM conversation on the child's main thread with the best thread DPI awareness the host accepts (per-monitor-v2 first), aborted by posting `WM_CLOSE` to the dialog thread. Only viable when the operator sits at the host's display — remote deployments compose [`-browse`](../directory-picker-browse/README.md) instead. The command boundary (`DirectoryPickerRunner`) and platform facts are injectable. The shared no-shell subprocess runner lives in [`dsh-native-command`](../../util/native-command/README.md).
+## Summary
 
-**Dual-face package**: the browser half (`./client`) registers a renderless flow occupant into [ui-workspace's](../../client/ui-workspace/README.md) two directory-flow holes — each `open` request drives `host.pickDirectory` and reports the one outcome (picked path / cancel / failure) through the hole's owner conversation. Both directory-flow declarations must be live before either contribution installs. One cordis.yml row therefore composes both sides of the native interaction; the client carries no capability-kind branching, and mounting a second flow package fails at load (the holes are `single` kind).
+An operator at the host's display picks a workspace directory through a native OS chooser: `dsh-host-directory-picker-native` opens one platform directory chooser per pick and resolves the chosen absolute path (`null` on cancel). macOS drives `osascript`, Linux uses Zenity with a KDialog fallback, and Windows opens the modern `IFileOpenDialog` in a spawned child process. Only viable when the operator sits at the host's display — remote deployments compose the [browse backend](../directory-picker-browse/README.md) instead. One composition row also registers the matching browser-side interaction in the workspace flow, so it selects both sides.

+## Use this package
+
+Compose this backend when the operator works at the host's display and a native chooser is the right interaction. A workspace flow that opens a directory picker calls `pick(signal)` once per open request; the returned promise resolves with the chosen absolute path, or `null` when the operator cancels.
+
+### When to choose it
+
+Choose this backend for a workstation-local operator on macOS, Windows, or desktop Linux. Choose the [browse backend](../directory-picker-browse/README.md) when clients cannot reach an OS chooser — remote browsers, SSH-forwarded sessions, or unattended hosts. When the situation varies, the [adaptive chooser](../directory-picker-auto/README.md) resolves it at boot.
+
+### What an operator experiences
+
+Each call opens one native chooser on the host display and waits for the operator; aborting the caller's signal terminates the chooser process instead of leaving it open. On Linux the chooser needs either Zenity or KDialog installed; with neither present, `pick` rejects with an actionable error instead of falling back to a typed-path prompt. The browser half of this package registers a renderless flow occupant into the workspace flow — every `open` request drives `host.pickDirectory` and reports the one outcome (picked path, cancel, or failure).
+
+### Observable failures
+
+A cancel returns `null`, not an error. Missing platform tooling, a failed chooser launch, or an aborted pick surfaces as a rejection the UI can present; the [browse backend](../directory-picker-browse/README.md) remains the composition-level fallback for deployments where native picking is unreliable.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+### Design concept
+
+The backend is a thin service over a platform chooser: `NativeDirectoryPicker` registers the `native` capability whose `pick` forwards to `pickNativeDirectory`, and the chooser runs as a subprocess so the host process never blocks on the dialog. The command boundary (`DirectoryPickerRunner`) and platform facts are injectable, and the shared no-shell subprocess runner lives in [`dsh-native-command`](../../util/native-command/README.md).
+
+### Platform mechanics
+
+Platform tools run without a shell: `osascript` on macOS, and Zenity with a KDialog fallback on Linux; the caller's abort terminates the native process. Windows opens the modern `IFileOpenDialog` in a spawned child process — a koffi-driven COM conversation on the child's main thread with the best thread DPI awareness the host accepts (per-monitor-v2 first), aborted by posting `WM_CLOSE` to the dialog thread.

+### 可观察的失败

 # @deepseek-ai/dsh-host-directory-picker
 
 English | [中文](README.zh.md)
 
-The web GUI host's workspace-directory picker is a capability seam. The abstract `DirectoryPicker` service (`ctx.directoryPicker`) is its Service Definition. Its only method, `capability()`, returns a discriminated union describing how an operator selects a directory. Backends differ in user interaction, not just implementation: `{ kind: 'native', pick(signal) }` opens one native OS chooser on the host display ([`-native`](../directory-picker-native/README.md)); `{ kind: 'browse', list(path?), createDirectory(path, name) }` provides listing and creation operations for an in-app browser, which works for remote clients that cannot reach an OS chooser ([`-browse`](../directory-picker-browse/README.md)). Consumers switch on `capability().kind`; the union derives from the merge-extensible `DirectoryPickerCapabilities` map, and a new backend adds its variant there through declaration merging. For an unknown kind, consumers hide directory picking rather than fail. The capability object must be stable for the service lifetime. Each backend package also has a browser entrypoint that registers the matching interaction in ui-workspace's directory-flow slots, so one composition row selects both the host capability and the client flow. A composition that should choose at runtime mounts [`-auto`](../directory-picker-auto/README.md), which inspects the host once at boot and mounts the matching backend row.
+## Summary
 
-Browse primitives fail with the typed `DirectoryPickerError` (`directory-unreadable` / `directory-exists` / `directory-create-failed`, each carrying the subject `path`), which the consuming gateway maps 1:1 onto wire error codes. `DirectoryEntry` rows carry a host-owned `hidden` flag (POSIX dot convention) so display policy stays client-side; `DirectoryListing.crumbs` is the ancestor chain from the filesystem root, every crumb a jump target. Design rationale, the `ctx.fs` separation, and the policy decisions live in [the directory-picker capability seam Agent Note](../../../.agents/notes/implemented/architecture/2026-07-28-directory-picker-capability-seam.md).
+The web GUI host lets an operator choose a workspace directory through one contract: a single service whose one method reports which interaction the composed backend provides. Backends differ in interaction shape, not just mechanism — the native backend opens an OS chooser on the host display, while the browse backend serves listing and creation primitives for an in-app browser that also works for remote clients. Consumers switch on the reported capability kind; a new backend extends the capability vocabulary without editing this package. This seam is GUI-host only and never reaches the agent loop; the backends and the wire mapping live beside it.

+### Choosing a backend
+
+The [native backend](../directory-picker-native/README.md) is the right choice when the operator sits at the host's display: `host.pickDirectory` opens one OS chooser and returns the chosen absolute path, or `null` on cancel. The [browse backend](../directory-picker-browse/README.md) works everywhere — it lists one directory level and creates child directories from the browser, so remote clients that cannot reach an OS dialog still pick a workspace. When the host situation varies between boots, compose the [adaptive chooser](../directory-picker-auto/README.md), which resolves the situation once at boot and mounts the matching backend.
+
+### The capability contract
+
+`capability()` returns a discriminated union describing how an operator selects a directory: `{ kind: 'native', pick(signal) }` for the OS chooser, or `{ kind: 'browse', list(path?), createDirectory(path, name) }` for the in-app browser. Consumers switch on `kind`; a capability kind no composition implements means the UI hides the picking affordance rather than failing. Browse failures throw the typed `DirectoryPickerError` with a closed code set — `directory-unreadable`, `directory-exists`, or `directory-create-failed` — each carrying the subject path, which the consuming gateway maps onto wire error codes.
+
+### What rows carry
+
+`DirectoryEntry` rows expose the absolute `path` and a host-owned `hidden` flag (dot-prefixed on POSIX) so display policy stays client-side; clients never join path segments themselves. `DirectoryListing.crumbs` is the ancestor chain from the filesystem root to the listed directory — every crumb is a jump target, and the root crumb is labeled by its full path.

+
+### Design concept
+
+The seam is built on one separation: the interaction shape a backend provides is a contract, not an implementation detail. `DirectoryPicker` is an abstract Cordis service with a single `capability()` method; a backend subclass registers as `ctx.directoryPicker`, and loading a second implementation throws the standard duplicate-service error. The capability object must be stable for the service lifetime because consumers may capture it across calls.
+
+### The merge-extensible vocabulary
+
+`DirectoryPickerCapabilities` is a merge-extensible map keyed by capability kind, and `DirectoryPickerCapability` derives the union from it. A new backend declaration-merges its shape here (the entry's `kind` literal must equal its key) instead of editing this package. Each backend package also ships a browser entrypoint that registers the matching interaction in ui-workspace's directory-flow slots, so one composition row selects both the host capability and the client flow.

+| [`src/index.ts`](src/index.ts) | Service Definition: abstract `DirectoryPicker`, capability vocabulary, typed error, Context merge |
+
+### Failure vocabulary
+
+`DirectoryPickerError` carries a closed `DirectoryPickerErrorCode` plus the absolute subject path, so consumers map business codes without string matching. The seam Agent Note records the design rationale, the separation from `ctx.fs`, and the policy decisions.

 [English](README.md) | 中文
 
-web GUI 宿主的工作区目录选择是一项能力 seam。抽象的 `DirectoryPicker` 服务（`ctx.directoryPicker`）是其 Service Definition。该服务只提供一个方法：`capability()`，它返回一个可辨识联合类型，说明操作者如何选择目录。后端之间的用户交互不同，不只是实现不同：`{ kind: 'native', pick(signal) }` 在宿主屏幕上打开一个原生 OS 选择器（[`-native`](../directory-picker-native/README.zh.md)）；`{ kind: 'browse', list(path?), createDirectory(path, name) }` 提供应用内浏览器使用的列举与创建操作，也能服务于无法访问 OS 对话框的远程客户端（[`-browse`](../directory-picker-browse/README.zh.md)）。消费方按 `capability().kind` 分支；联合类型由可合并扩展的 `DirectoryPickerCapabilities` 映射派生，新后端通过声明合并在其中加入自己的变体。遇到未知 kind 时，消费方会隐藏目录选择入口，而不是失败。能力对象在服务生命周期内必须保持稳定。每个后端包还提供 browser 入口，在 ui-workspace 的 directory-flow slot 中注册匹配的交互，因此一项组合配置会同时选择宿主能力与 client 流程。需要在运行时选择交互的组合挂载 [`-auto`](../directory-picker-auto/README.zh.md)，它在启动时检查一次宿主情况，并挂载匹配的后端行。
+## 概述
 
-浏览原语失败时会抛出带类型的 `DirectoryPickerError`（`directory-unreadable`／`directory-exists`／`directory-create-failed`，各自携带出错对象的 `path`），消费网关将其 1:1 映射为协议错误码。`DirectoryEntry` 行携带宿主判定的 `hidden` 标志（POSIX 点前缀约定），展示策略留在客户端；`DirectoryListing.crumbs` 是从文件系统根开始的祖先链，每个 crumb 都是跳转目标。设计依据、与 `ctx.fs` 的切分、策略裁决见 [目录选择能力 seam Agent Note](../../../.agents/notes/implemented/architecture/2026-07-28-directory-picker-capability-seam.zh.md)。
+web GUI 宿主通过一份约定让操作者选择工作区目录：一个只提供一个方法的服务，该方法报告所组合后端提供的是哪种交互。后端之间的差异在于交互形态，而不仅仅是机制——原生后端在宿主屏幕上打开一个 OS 选择器，浏览后端则为应用内浏览器提供列举与创建原语，也能服务于远程客户端。消费方按报告的能力类型分支；新后端无需修改本包即可扩展能力词汇。该 seam 只服务 GUI 宿主，绝不进入 agent loop；后端与协议映射就在它旁边。

+## 使用本包
+
+挂载且只挂载一个目录选择后端，然后让工作区流程驱动它：seam 本身只是服务约定，因此没有后端的组合就无从选择目录。
+
+### 选择后端
+
+当操作者坐在宿主屏幕前时，[原生后端](../directory-picker-native/README.zh.md)是正确选择：`host.pickDirectory` 打开一个 OS 选择器，返回所选绝对路径，取消时返回 `null`。[浏览后端](../directory-picker-browse/README.zh.md)处处可用——它在浏览器中列举一个目录层级并创建子目录，因此无法触达 OS 对话框的远程客户端依然能选择工作区。当宿主处境在两次启动之间变化时，组合[自适应选择器](../directory-picker-auto/README.zh.md)，它在启动时判定一次处境并挂载匹配的后端。
+
+### 能力约定
+
+`capability()` 返回一个可辨识联合类型，说明操作者如何选择目录：OS 选择器为 `{ kind: 'native', pick(signal) }`，应用内浏览器为 `{ kind: 'browse', list(path?), createDirectory(path, name) }`。消费方按 `kind` 分支；某个组合没有实现的能力类型意味着界面隐藏选择入口，而不是失败。浏览失败抛出带类型的 `DirectoryPickerError`，其错误码集合是封闭的——`directory-unreadable`、`directory-exists` 或 `directory-create-failed`——每个都携带出错对象的路径，消费网关将其 1:1 映射为协议错误码。
+
+### 行携带什么
+
+`DirectoryEntry` 行暴露绝对 `path` 与宿主判定的 `hidden` 标志（POSIX 上为点前缀约定），展示策略留在客户端；客户端绝不自行拼接路径段。`DirectoryListing.crumbs` 是从文件系统根到被列举目录的祖先链——每个 crumb 都是跳转目标，根 crumb 以完整路径标注。

+<summary>实现细节——点击展开</summary>
+
+### 设计理念
+
+该 seam 建立在一个分离之上：后端提供的交互形态是约定，而不是实现细节。`DirectoryPicker` 是只有一个 `capability()` 方法的抽象 Cordis 服务；后端子类以 `ctx.directoryPicker` 注册，加载第二个实现会抛出标准的重复服务错误。能力对象在服务生命周期内必须保持稳定，因为消费方可能跨调用持有它。
+
+### 可合并扩展的词汇表
+
+`DirectoryPickerCapabilities` 是以能力类型为键的可合并扩展映射，`DirectoryPickerCapability` 从它派生联合类型。新后端在此通过声明合并且只修改这里（条目的 `kind` 字面量必须等于其键），而不改动本包。每个后端包还随附一个 browser 入口，在 ui-workspace 的 directory-flow slot 中注册匹配的交互，因此一行组合配置同时选择宿主能力与客户端流程。

-SPA dist server for the Web shell: a function plugin (config `{distIndex}`) that claims the [webserver](../webserver/README.md)'s single fallback seat and serves the built frontend directory with explicit index entry points. While `distIndex` is readable, the dist root and configured index path render `index.html` with HTTP 200; other existing files are served directly. An absent or non-file target inside the dist root, including a missing configured index, returns an empty 404; traversal outside the dist root returns 403, unknown extensions ship as `application/octet-stream`, and non-GET/HEAD without a matching named route returns 405. Every successful index response is rendered through the webserver's `renderIndex` — structured injection rows first, then the raw index taps — which is how the boot manifest reaches the page. `distIndex` is an assembly fact of the composing application: [`dsh-web-app`](../../bundle/web-app/README.md) resolves it through the frontend package's exports and mounts this plugin; a deployment never hardcodes it.
+## Summary
 
-Root and configured-index responses require `ctx.connection.authorizeIndex` before reading the HTML bytes. A valid process token receives a 303 redirect plus the persistent browser cookie; an existing valid cookie serves the index; every other index request receives the Connection-owned 401 response. Non-index files remain public static assets. Connection owns all token, cookie, expiry, and signing-record semantics; this package only places that decision before the HTML read.
+Browsers get the built Web shell from `dsh-host-frontend-static`: it claims the [webserver](../webserver/README.md) fallback seat and serves the built frontend directory with locked semantics — only the dist root and the configured index path render `index.html` (HTTP 200), other existing files are served directly, an absent or non-file target inside the dist root — including a missing configured index — returns an empty 404, traversal outside the dist root is 403, unknown extensions ship as `application/octet-stream`, and non-GET/HEAD without a matching named route is 405. Every successful index response is rendered through the webserver's `renderIndex`, which is how the boot manifest reaches the page. The fallback seat is single-owner: a second claim throws, and unloading the plugin releases the seat.
 
-The fallback seat is single-owner (a second claim throws) and effect-scoped: disposing the plugin's fiber releases the seat, after which the unclaimed webserver answers 404.

+## Use this package
+
+Compose this plugin in a browser-facing host that serves the built Web shell: it claims the webserver's fallback seat and answers every request no named route matches. It needs one config value — where the built frontend's `index.html` lives.
+
+### Minimal configuration
+
+```yaml
+- name: '@deepseek-ai/dsh-host-frontend-static'
+  config:
+    distIndex: /absolute/path/to/dist/index.html
+```
+
+`distIndex` is an assembly fact of the composing application: [`dsh-web-app`](../../bundle/web-app/README.md) resolves it through the frontend package's exports and mounts this plugin; a deployment never hardcodes it.
+
+### What the server enforces
+
+Requests are served from the dist root (the directory containing `distIndex`). The dist root and the configured index path render `index.html` with HTTP 200; any other existing file is served directly with its MIME type, and unknown extensions ship as `application/octet-stream`. A path that resolves outside the root is rejected with 403, so a crafted path cannot read files above the dist. An absent or non-file target inside the dist root — a missing file, a directory, or a missing configured index — returns an empty 404. Non-GET/HEAD requests without a matching named route are answered 405. Every successful index response is rendered through the webserver's `renderIndex`, so the boot manifest reaches the page on `/` and on the configured index path.
+
+Root and configured-index responses call `ctx.connection.authorizeIndex` before reading HTML. A valid process token receives a 303 redirect plus the persistent browser cookie; an existing valid cookie serves the index; every other index request receives the Connection-owned 401 response. Non-index files remain public static assets. Connection owns the token, cookie, expiry, and signing-record semantics.
+
+### Observable failures
+
+Traversal returns 403 rather than an error page. An absent or non-file target inside the dist root returns an empty 404, so a stale link or a mistyped pathname is an explicit failure rather than a silent SPA fallback. Claiming the seat twice throws, and while the seat is unclaimed the webserver answers 404 — which is what a browser sees if this plugin's fiber is disposed.
+
+-----
+
+<a id="understand-the-implementation"></a>
+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+### Design concept
+
+The package is one function plugin around `serveStatic`: `apply` resolves the dist root from `distIndex`, builds a `renderIndex` closure that runs `ctx.webServer.renderIndex` over the raw `index.html`, and registers the fallback handler under an effect scope. The seat is single-owner by the webserver's contract — a second registration throws — and effect-scoped, so disposing the fiber releases the seat.
+
+### The traversal fence
+
+`serveStatic` normalizes the requested pathname and joins it to the dist root, then requires the target to be the root itself or stay under it. The check uses `sep` rather than `/` because `resolve()` emits backslash paths on Windows, where a `/` suffix would reject every legitimate subpath as traversal.

+## 使用本包
+
+在服务已构建 Web 壳的浏览器宿主中组合本插件：它占据 webserver 的回退席位，并应答所有未被具名路由命中的请求。它只需要一个配置值——已构建前端的 `index.html` 位于何处。
+
+### 最小配置
+
+```yaml
+- name: '@deepseek-ai/dsh-host-frontend-static'
+  config:
+    distIndex: /absolute/path/to/dist/index.html
+```
+

+
+### 服务器强制什么
+
+请求从 dist 根目录（包含 `distIndex` 的目录）提供。dist 根目录与配置的 index 路径以 HTTP 200 渲染 `index.html`；任何其他已有文件按自身 MIME 类型直接提供，未知扩展名按 `application/octet-stream` 提供。解析到根目录之外的路径以 403 拒绝，因此精心构造的路径无法读取 dist 之上的文件。dist 根目录内缺失或非文件的 target——文件缺失、目录或配置的 index 缺失——返回空 404。没有匹配具名路由的非 GET／HEAD 请求回答 405。每个成功的 index 响应都经 webserver 的 `renderIndex` 渲染，因此启动 manifest 在 `/` 与配置的 index 路径上到达页面。
+
+根路径与配置的 index 响应会在读取 HTML 前调用 `ctx.connection.authorizeIndex`。有效进程 token 会得到 303 重定向与持久浏览器 cookie；已有有效 cookie 时直接提供 index；其他 index 请求得到 Connection 所有的 401 响应。非 index 文件仍是公开静态资源。Token、cookie、过期时间与签名记录语义都归 Connection 所有。
+

+
+本包是围绕 `serveStatic` 的一个函数插件：`apply` 从 `distIndex` 解析出 dist 根目录，构建一个对原始 `index.html` 运行 `ctx.webServer.renderIndex` 的 `renderIndex` 闭包，并在 effect 作用域下注册回退 handler。按 webserver 的约定，席位只有单一所有者——第二次注册会抛错——且受 effect 作用域约束，因此 dispose fiber 即释放席位。

+`serveStatic` 规范化请求的 pathname 并拼接到 dist 根目录，然后要求目标就是根目录本身或保持在它之下。检查使用 `sep` 而非 `/`，因为 `resolve()` 在 Windows 上输出反斜杠路径，此时 `/` 后缀会把每个合法子路径都当作遍历拒绝。

-Read-only Host projection of the current Cordis Loader tree. `PluginInventoryGateway` registers the `pluginInventory` service and publishes one generated direct Remote, `pluginInventory/list`. Every call reads `ctx.loader.entries()` directly, skips structural group rows, and returns the remaining entries in Loader order with only their Loader entry id, module specifier, effective enablement, and current root Fiber phase.
+## Summary
 
-The phase is `pending`, `loading`, `active`, `failed`, or `unloading`; it is `null` when the entry has no live root Fiber. The snapshot is intentionally point-in-time: Loader remains the sole lifecycle authority, while this package owns no cache, history, provenance model, event stream, or mutation path. Its public payload types live under `./types`, and Typert generates the Host and Client Remote artifacts exposed by `./typert` and `./remote`.
+Clients and settings pages can show what is currently composed in the host: calling `pluginInventory/list` returns the current non-group Loader entries in Loader order — entry id, module specifier, effective enablement, and root Fiber phase (`pending`, `loading`, `active`, `failed`, or `unloading`, or `null` when an entry has no live root Fiber). The snapshot is point-in-time: the Loader is the sole lifecycle authority, and this package owns no cache, history, provenance model, event stream, or mutation path. Client packages consume the Remote through the explicit [`api-remotes`](../../api/remotes/README.md) assembly rather than importing the Host implementation.
 
-The service is Remote-only and deliberately declares no same-process Cordis `Context` merge. Client packages consume it through the explicit [`api-remotes`](../../api/remotes/README.md) assembly rather than importing the Host implementation.

+## Use this package
+
+Call `pluginInventory/list` when a client or settings page needs to show what is currently composed in the host — which plugins are loaded, enabled, and alive. The Remote is the only entry point: the service is Remote-only and deliberately declares no same-process Cordis `Context` merge.
+
+### What a snapshot contains
+
+Each row is one non-group Loader entry: its entry id, the exact module specifier, the effective enablement (including disabled ancestor groups), and the current root Fiber phase. `pending` means the entry waits to load, `loading` that it is being read, `active` that it is running, `failed` that its fiber rejected, and `unloading` that it is being torn down; `null` means no live root Fiber exists at all. Structural group rows are skipped.
+
+### What you can and cannot do with it
+
+The inventory is a snapshot for display and diagnostics: a client can render the roster, flag failed entries, and detect changes by comparing snapshots. It cannot enable, disable, add, or remove plugins, and it carries no history — a fiber that already failed and was removed is absent. Because the service reads the Loader on every call, the answer always reflects the current composition rather than a cached view.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+### Design concept
+
+The gateway is a direct projection with no second lifecycle truth: every `list()` call reads `ctx.loader.entries()` and maps each non-group entry to its public row. Cordis's internal plugin/status events already maintain `Entry.fiber` and `Fiber.state`, so a cache would only add another lifecycle truth to keep synchronized.
+
+### The phase mapping
+
+Fiber states map onto the public phase vocabulary, with `disposed` folding into `null` — an entry whose fiber is gone has no live root to report. The phase therefore never distinguishes why no live root exists: the entry may never have started, or its fiber may already have been disposed.
+

 ## Model Experience
 
-None, as this Host-only inventory projection registers no prompt, tool, message, or provider request.
+None, as the host-side read-only Loader projection registers nothing model-facing.

 ## Known Limitations and Deferred Work
 
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define what a point-in-time inventory cannot tell a client. They are current package constraints, not a task backlog.
+
 - **Point-in-time state only** — the result contains no durable failure history or subscription; a missing root Fiber is reported as `null`, regardless of why no live root exists.
 - **No provenance or mutation** — the service does not identify which bundle, profile, or override introduced an entry, and it cannot enable, disable, add, or remove plugins.

+
+每一行是一个非组 Loader 条目：其条目 id、精确模块标识、有效启用状态（含被禁用的祖先组）与当前根 Fiber 阶段。`pending` 表示条目等待加载，`loading` 表示正在读取，`active` 表示正在运行，`failed` 表示其 fiber 被拒绝，`unloading` 表示正在拆除；`null` 表示完全不存在存活的根 Fiber。结构性的 group 行会被跳过。

+### 阶段映射
+
+Fiber 状态映射到公共阶段词汇，其中 `disposed` 折叠为 `null`——fiber 已消失的条目没有可报告的存活根。因此阶段从不区分为什么没有存活根：条目可能从未启动，也可能其 fiber 已被释放。

 English | [中文](README.zh.md)
 
-Web HTTP and upgrade-route registration plugin (default-exported `WebServer`, config `{host, port, compression?, compressionLevel?, compressionThresholdBytes?}`): a `node:http` server that listens on activation and provides `ctx.webServer`. `register(route)` adds a named `exact`/`prefix` HTTP route; `registerUpgrade(route)` adds an upgrade route for an exact pathname. A duplicate path within either table throws because route patterns are a composition-level contract and a collision is a misconfiguration; both methods return a disposer that removes the registration. `registerFallback(handler)` registers the one handler for requests that match no named route. A second registration throws; the SPA dist server [`dsh-host-frontend-static`](../frontend-static/README.md) is the shipped owner, and the server returns 404 while none is registered. Index startup inputs are structured rows: `collectIndexInjections()` gathers a fresh `IndexInjection` table over one `webserver/index-inject` emit per call, and `renderIndex(html)` renders the rows into an index.html body before applying the raw `tapIndex(transform)` transforms in registration order (`applyIndexTaps(html)`, the escape hatch for markup no row expresses); `script-preload` rows render advisory classic-script preload links. The fallback handler calls `renderIndex` on every index response, and a static deployment ships the same rows over its boot payload. `port` reads the listening port (the OS-assigned value when `port` is 0), and `host` reads the configured bind host (composition-time facts other plugins adapt to, e.g. the directory-picker chooser). HTTP match order is fixed: exact over the whole table, then longest prefix, then the fallback handler. Upgrades match exactly and unmatched connections are closed; registration order carries no request-facing semantics.
+## Summary
 
-`compression: 'gzip'` wraps socket-backed HTTP responses without changing route APIs. The client must prefer gzip and the media type must be compressible; known response lengths below `compressionThresholdBytes` stay identity, while unknown-length streams are eligible immediately. `compressionLevel` controls DEFLATE effort. Existing content encodings, `Cache-Control: no-transform`, range responses, SSE, ZIP, and the packaged `.gz` Worker image stay unmodified. The shipped Web bundle enables level 1 with a 1024-byte threshold; other compositions default to `compression: 'none'`. The Web Worker tunnel does not carry the browser-managed `Accept-Encoding` header, so its synthetic responses remain identity bytes.
+Browsers reach the web GUI over HTTP through `dsh-host-webserver`: a `node:http` server where other plugins register named routes, upgrade routes, index startup inputs, and one fallback handler. It knows no harness concepts and serves no files — the `/api` bridge, plugin bundles, the HMR event stream, and the SPA dist belong to the plugins that register them. Route matching is fixed: exact over the whole table, then longest prefix, then the fallback handler. It serves browsers only; Electron loads dist over `file://` and carries fetch over an IPC bridge.
 
-The package knows no harness concepts and serves no files: the `/api` HTTP bridge and downlink WebSockets are routes owned by the connection plugin, plugin bundles and the HMR event stream are routes owned by the modules/hmr plugins, and dist serving belongs to the fallback owner. The upgrade handler owns the protocol handshake and connection contents; the webserver only delivers the raw socket and request. `host` accepts only `127.0.0.1` (default posture) and `0.0.0.0` (deliberate network exposure). This server serves browsers only; Electron loads dist over `file://` and carries fetch over an IPC bridge. This package never prints; the URL line belongs to the shell.
+## Table of Contents
 
-A listen failure (EADDRINUSE…) throws out of activation and rejects Loader composition with the bind diagnostic; the failed candidate fiber is disposed. An HTTP request whose handling throws (a fallback owner's `decodeURIComponent` on a malformed %-escape, a client dropping mid-body) is answered 400 — or the socket destroyed when headers are already out — and logged as a warning; it never exits the process. An upgrade-handler exception or upgraded-socket transport error is logged as a warning and destroys its socket. Disposal starts `close()` and `closeAllConnections()`, destroys every tracked upgraded socket, and returns only after the HTTP server and those sockets have closed.

+<a id="use-this-package"></a>
+## Use this package
+
+Compose the webserver as the HTTP transport of a browser-facing host, then let the feature plugins claim their routes. Activation listens immediately; registration order carries no request-facing semantics because named routes compose to be disjoint.
+
+### Minimal configuration
+
+```yaml
+- name: '@deepseek-ai/dsh-host-webserver'
+  config:
+    host: 127.0.0.1
+    port: 3000
+```
+
+`host` accepts exactly two values: `127.0.0.1` (default posture, loopback only) and `0.0.0.0` (deliberate network exposure — the server carries no TLS, authentication, or origin policy of its own). `port` 0 requests an OS-assigned port; `ctx.webServer.port` reads the listening port afterwards.
+
+Set `compression: 'gzip'` to wrap eligible socket-backed responses without changing route APIs. The client must accept gzip and the media type must be compressible; known response lengths below `compressionThresholdBytes` remain uncompressed, while unknown-length streams are eligible immediately. Existing encodings, `Cache-Control: no-transform`, range responses, SSE, ZIP, and the packaged `.gz` Worker image remain unchanged. The shipped Web bundle uses compression level 1 with a 1024-byte threshold; other compositions default to no compression.
+
+### Registering routes
+
+`register(route)` adds a named `exact` or `prefix` HTTP route, `registerUpgrade(route)` adds an upgrade route for an exact pathname, and both return a disposer that removes the registration. A duplicate path within either table throws — route patterns are a composition-level contract, so a collision is a misconfiguration. HTTP matching is exact over the whole table, then longest prefix, then the fallback handler; upgrades match exactly and unmatched connections are closed.
+
+### The fallback seat
+
+`registerFallback(handler)` claims the one handler for every request no named route matches. A second registration throws; while no fallback is registered the server answers 404. In the shipped Web composition the [SPA dist server](../frontend-static/README.md) owns the seat and calls `renderIndex` on every index response it renders.
+
+Index startup inputs are two layers. `collectIndexInjections()` gathers a fresh injection table — one `webserver/index-inject` emit per call, each subscriber pushing its current rows — and `renderIndex(html)` renders those rows into the index.html body before applying the raw `tapIndex(transform)` transforms in registration order. A `script-preload` row renders an advisory classic-script preload link. Static deployments carry the same rows in their boot payload. `applyIndexTaps(html)` applies only the raw transforms; it is the escape hatch for markup no row expresses.
+
+### Behavior under failure
+
+A listen failure (for example EADDRINUSE) rejects plugin initialization with the bind diagnostic. An HTTP request whose handler throws is answered 400 — or the socket destroyed when headers are already out — and logged as a warning; it never exits the process. An upgrade-handler exception or upgraded-socket transport error logs a warning and destroys its socket.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+### Design concept
+
+The package is a plain route registry with no harness vocabulary: `WebServer` extends Cordis `Service` and holds three route tables plus the fallback slot, the raw index-tap list, and the `webserver/index-inject` event the index renderer gathers rows through. Index rendering composes two layers per response: `renderIndex` renders the fresh injection table, including advisory `script-preload` rows, into the body, then applies the raw taps in registration order; `applyIndexTaps` runs the taps alone. The upgrade handler owns the protocol handshake and connection contents; the webserver only delivers the raw socket and request. `host` and `port` getters expose composition-time facts other plugins adapt to (for example the directory-picker chooser).
+
+### Matching and lifecycle
+
+`match(pathname)` consults the exact table first, then walks the prefix table for the longest match, then the fallback. Activation (`[Service.init]`) listens immediately; disposal starts `close()` and `closeAllConnections()`, destroys every tracked upgraded socket, and returns only after the server and those sockets have closed. Node does not include upgraded sockets in `closeAllConnections()`, so the service tracks them explicitly.

-Web HTTP 与 upgrade route 注册插件（默认导出 `WebServer`，配置为 `{host, port, compression?, compressionLevel?, compressionThresholdBytes?}`）：一个在激活时开始监听的 `node:http` 服务器，提供 `ctx.webServer`。`register(route)` 添加具名的 `exact`／`prefix` HTTP route；`registerUpgrade(route)` 添加精确 pathname 的 upgrade route；同一张表内的重复路径会抛错，因为 route 模式是组合层约定，冲突即配置错误；两者返回的 disposer 都会移除注册。`registerFallback(handler)` 注册一个 handler，处理所有未被具名 route 命中的请求。第二次注册会抛错；随附的 SPA dist 服务器 [`dsh-host-frontend-static`](../frontend-static/README.zh.md) 是该 handler 的所有者，没有注册 handler 时服务器返回 404。index 的启动输入是结构化行：`collectIndexInjections()` 每次调用经一次 `webserver/index-inject` emit 现收一张全新的 `IndexInjection` 表，`renderIndex(html)` 先把行渲染进 index.html 响应体，再按注册顺序应用原始的 `tapIndex(transform)` 转换（`applyIndexTaps(html)`，行无法表达的标记的逃生口）；`script-preload` 行渲染为 classic script 的提示性预加载链接。fallback handler 在每次 index 响应时调用 `renderIndex`，静态部署则把同一批行经 boot 载荷下发。`port` 读取正在监听的端口（当 `port` 为 0 时读取 OS 分配的值），`host` 读取配置的绑定宿主（这些是其他插件据以自适应的组合期事实，例如 directory-picker 选择器）。HTTP 匹配顺序固定不变：先在整张表中匹配精确 route，再匹配最长前缀，最后交给 fallback handler。upgrade 只做精确匹配，未命中连接直接关闭；注册顺序不影响请求处理。
+## 概述
 
-`compression: 'gzip'` 会包装基于 socket 的 HTTP 响应，而不改变 route API。客户端必须偏好 gzip，且媒体类型必须可压缩；已知长度低于 `compressionThresholdBytes` 的响应保持 identity，未知长度的 stream 则直接具备压缩资格。`compressionLevel` 控制 DEFLATE 强度。已有内容编码、`Cache-Control: no-transform`、范围响应、SSE、ZIP 与打包后的 `.gz` Worker 镜像均保持原样。随附的 Web 组合启用 level 1 和 1024 字节阈值；其他组合默认使用 `compression: 'none'`。Web Worker 隧道不携带浏览器管理的 `Accept-Encoding` 请求头，因此其合成响应仍为 identity 字节。
+浏览器经由 `dsh-host-webserver` 通过 HTTP 访问 web GUI：一个 `node:http` 服务器，其他插件在其中注册具名路由、upgrade 路由、index 启动输入与一个回退 handler。它不了解任何 harness 概念，也不提供任何文件服务——`/api` 桥接、插件 bundle、HMR（热模块替换）事件流与 SPA dist 都属于注册它们的插件。路由匹配顺序固定不变：先在整张表中匹配精确 route，再匹配最长前缀，最后交给回退 handler。它只服务浏览器；Electron 通过 `file://` 加载 dist，并经 IPC 桥接承载 fetch。
 
-该包不了解任何 harness 概念，也不提供任何文件服务：`/api` HTTP 桥接与下行 WebSocket 是 connection 插件的 route，插件 bundle 与 HMR（热模块替换）事件流是 modules／hmr 插件的 route，dist 服务则属于 fallback 持有者。upgrade handler 拥有协议握手与连接内容；webserver 只交付原始 socket 与 request。`host` 只接受 `127.0.0.1`（默认安全姿态）和 `0.0.0.0`（有意向网络开放）。该服务器只服务浏览器；Electron 通过 `file://` 加载 dist，并经 IPC 桥接承载 fetch。该包从不打印内容；URL 行属于 shell。
+## 目录
 
-监听失败（EADDRINUSE……）会从激活过程抛出，并以绑定诊断信息拒绝 Loader 组合；失败的候选 fiber 会被 dispose（资源释放）。处理 HTTP 请求时抛错（例如 fallback 持有者的 `decodeURIComponent` 收到格式错误的百分号转义，或客户端在请求体传输中途断开）时，服务器会响应 400；若响应头已经发出，则销毁 socket，并记录 warning，但绝不会退出进程。upgrade handler 抛错或升级 socket 出现传输错误时，会记录 warning 并销毁对应 socket。资源释放会启动 `close()` 与 `closeAllConnections()`，销毁所有受跟踪的升级 socket，并仅在 HTTP server 与这些 socket 均已关闭后返回。

+## 使用本包
+
+把 webserver 组合为面向浏览器宿主的 HTTP 传输，然后让功能插件认领各自的路由。激活即开始监听；注册顺序不影响请求处理，因为具名路由组合起来互不相交。
+
+### 最小配置
+
+```yaml
+- name: '@deepseek-ai/dsh-host-webserver'
+  config:
+    host: 127.0.0.1
+    port: 3000
+```
+
+`host` 只接受两个值：`127.0.0.1`（默认姿态，仅回环）与 `0.0.0.0`（有意向网络开放——服务器自身不携带 TLS、认证或来源策略）。`port` 为 0 时请求 OS 分配端口；之后用 `ctx.webServer.port` 读取正在监听的端口。
+
+设置 `compression: 'gzip'` 可以包装符合条件的 socket-backed 响应，而不改变 route API。客户端必须接受 gzip，且媒体类型必须可压缩；已知长度小于 `compressionThresholdBytes` 的响应保持未压缩，未知长度 stream 则立即符合条件。已有编码、`Cache-Control: no-transform`、range 响应、SSE、ZIP 与已打包的 `.gz` Worker image 均保持不变。随附 Web bundle 使用 level 1 与 1024 字节阈值；其他组合默认不压缩。
+
+### 注册路由
+
+`register(route)` 添加具名的 `exact`／`prefix` HTTP route，`registerUpgrade(route)` 为精确 pathname 添加 upgrade route，两者返回的 disposer 都会移除注册。同一张表内的重复路径会抛错——route 模式是组合层约定，冲突即配置错误。HTTP 匹配先在整张表中匹配精确 route，再匹配最长前缀，最后交给回退 handler；upgrade 只做精确匹配，未命中连接直接关闭。
+
+### 回退席位
+
+`registerFallback(handler)` 认领所有未被具名 route 命中的请求的唯一个 handler。第二次注册会抛错；没有注册回退时服务器回答 404。在随附的 Web 组合中，[SPA dist 服务器](../frontend-static/README.zh.md)拥有该席位，并对其渲染的每个 index 响应调用 `renderIndex`。
+
+index 启动输入分两层。`collectIndexInjections()` 收集一张全新的注入表——每次调用发一次 `webserver/index-inject` 事件，每个订阅方推入其当前行——`renderIndex(html)` 先把这些行渲染进 index.html 正文，再按注册顺序应用原始 `tapIndex(transform)` 转换。`script-preload` 行会渲染为 classic script 的提示性 preload 链接。静态部署会在启动 payload 中携带同一批行。`applyIndexTaps(html)` 只应用原始转换；它是任何行都无法表达的标记的逃生口。
+
+### 失败时的行为
+
+监听失败（例如 EADDRINUSE）会以绑定诊断信息拒绝插件初始化。handler 抛错的 HTTP 请求会得到 400——若响应头已经发出则销毁 socket——并记录 warning；它绝不会退出进程。upgrade handler 抛错或升级 socket 出现传输错误时，会记录 warning 并销毁对应 socket。

+## 理解实现
+
+<details>
+<summary>实现细节——点击展开</summary>
+
+### 设计理念
+
+本包是一个不带任何 harness 词汇的普通路由注册表：`WebServer` 继承 Cordis `Service`，持有三张路由表、回退槽位、原始 index 转换列表，以及 index 渲染器经其收集行的 `webserver/index-inject` 事件。index 渲染每次响应组合两层：`renderIndex` 先把包含提示性 `script-preload` 行的全新注入表渲染进正文，再按注册顺序应用原始转换；`applyIndexTaps` 只运行转换。upgrade handler 拥有协议握手与连接内容；webserver 只交付原始 socket 与 request。`host` 与 `port` getter 暴露其他插件据以自适应的组合期事实（例如 directory-picker 选择器）。
+
+### 匹配与生命周期
+
+`match(pathname)` 先查精确表，再遍历前缀表取最长匹配，最后走回退。激活（`[Service.init]`）即开始监听；资源释放会启动 `close()` 与 `closeAllConnections()`，销毁所有受跟踪的升级 socket，并仅在服务器与这些 socket 均已关闭后返回。Node 的 `closeAllConnections()` 不包含升级 socket，因此服务显式跟踪它们。

 # @deepseek-ai/dsh-anonymous-user-id
 
 English | [中文](README.zh.md)
 
-Shared anonymous identity for session telemetry, direct feedback acknowledgement, and DeepSeek provider requests. `getOrCreateAnonymousUserId()` returns a random UUID v4 scoped to one harness home, persisted as the bare line `$DSH_HOME/.anonymous-user-id` (`~/.dsh/.anonymous-user-id` when `DSH_HOME` is unset). The OpenTelemetry backend reports it as Resource `user.id`; `/feedback` includes the same value in its acknowledgement; and `dsh-llm-deepseek` sends it as `x-deepseek-harness-user-id`, allowing the receiving systems to correlate records without independently generated identities.
+## Summary
 
-The identity is never derived from the hostname, network address, git remote, or another identifying source. Deleting `.anonymous-user-id` resets the identity on the next process launch. Separate harness homes have separate identities.
+Every harness home gets one anonymous id that telemetry, feedback, and DeepSeek requests attach to their records, so receiving systems can tell that records came from the same installation without learning who the user is. The id is a random UUID stored in `$DSH_HOME/.anonymous-user-id` (`~/.dsh` by default); it appears automatically the first time one of those features runs, stays stable across restarts, and is created fresh if you delete the file. Separate harness homes never share an id, and no machine or account detail goes into it. Use it whenever you want to correlate records from one installation without an account; it cannot join records across different homes.
 
-## Storage contract
+## Table of Contents
 
-Reads and writes are synchronous because both boot-time telemetry construction and direct command execution need one API. The result is memoized per resolved file path for the process lifetime. A first writer uses exclusive creation and a concurrent loser adopts the persisted winner; a corrupt file is replaced. Persistence is best-effort, so an unwritable home still receives a process-local UUID rather than blocking telemetry or feedback.

-## Composition
+-----
 
-This package is a shared library, not a Cordis plugin. Consumers import `getOrCreateAnonymousUserId()` directly. Its invariant companion is intentionally empty because the package owns no event stream or public mutable relation that can be checked without creating the identity as a side effect. `DSH_TELEMETRY_DISABLED` stops telemetry export only; it does not suppress direct feedback acknowledgement or the DeepSeek provider header.
+<a id="use-this-package"></a>
+## Use this package
 
+When you want the records your installation sends out to be recognizable as coming from the same harness home — telemetry, feedback, and DeepSeek requests all carry one shared id — this package is what provides it. There is nothing to install or configure: the id appears automatically, and the shipped feedback, telemetry, and DeepSeek features already use it. Do not use it to identify a user or to join records across different homes; it is anonymous and home-scoped.
+
+### What the id does for you
+
+Three things your installation sends out carry the same id, so records line up across all of them:
+
+- **Session telemetry** — your telemetry exports carry the id as the `user.id` resource attribute, so a collector can group an installation's records.
+- **Feedback** — each feedback acknowledgement names the anonymous installation that recorded it.
+- **DeepSeek requests** — every provider request carries the `x-deepseek-harness-user-id` header, so usage can be attributed per installation.
+
+### Observing and resetting the id
+
+The id lives in `$DSH_HOME/.anonymous-user-id` (`~/.dsh` by default) as a plain UUID text file. Delete that file to get a fresh id at the next launch; the running process keeps its current id until it exits. Separate harness homes keep separate ids, and no machine or account detail ever goes into the value.
+
+### Using it in your own package
+
+When you build a feature that should share the installation's anonymous id, import the value once and reuse it — telemetry, feedback, and DeepSeek already use the same id, so your records line up with theirs:
+
+```ts
+import { getOrCreateAnonymousUserId } from '@deepseek-ai/dsh-anonymous-user-id'
+
+const userId = getOrCreateAnonymousUserId() // stable for the process lifetime
+```
+
+The value is stable for the process and matches what the built-in features use; it changes only when the file is deleted and a later launch mints a replacement. Even when the home directory cannot be written, the value still works for the current run, so records keep flowing.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the package and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+- **Random, never derived.** The id comes from `crypto.randomUUID()`; it is never derived from the hostname, network address, git remote, or any other identifying source, so anonymity is a property of the mint.
+- **Synchronous and memoized.** One process touches the disk once: reads and writes are synchronous, and the result is memoized per resolved file path.
+- **Best-effort persistence.** A write failure still returns a usable id for the run, so telemetry and feedback never block on an unwritable home.
+- **Library, not plugin.** There is no Cordis plugin entry or config; the invariant companion installs an empty installer because the package owns no event stream or public mutable relation to compare without creating the id as a side effect.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Library entry: `getOrCreateAnonymousUserId`, file persistence, per-path memoization |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion with an empty installer (no runtime invariant; the only relation is private and side-effecting) |
+| [`tests/anonymous-user-id.spec.ts`](tests/anonymous-user-id.spec.ts) | Exercised behavior: mint, persistence, corruption, concurrency, memoization |
+| [`tests/invariant.spec.ts`](tests/invariant.spec.ts) | Companion registration through the invariants service |
+
+### The API
+
+The package exposes one function that returns the installation's anonymous id, minting and persisting it on first use; the exact signature, options, and defaults live in `src/index.ts`.
+
+### Storage contract
+
+The file is a bare UUID line named by `ANONYMOUS_USER_ID_FILE_NAME`, validated against a UUID pattern on read. A first writer uses exclusive creation (`wx`); a concurrent loser rereads and adopts the winner's value. A corrupt or unreadable file falls through to mint-and-overwrite. Memoization is keyed by resolved file path, so distinct homes never share an id.

+
+This Dev Note is working context for maintainers: open questions and directions that are not decided. It is explicitly non-authoritative — shipped behavior, limits, and accepted rationale live in the sections above and the package code, and conclusions migrate there once they stabilize.
+
+#### Open: file-format evolution
+
+The persistence contract is a bare UUID line with no version marker. Adding a second value beside the id, or wrapping the line in a container, has no migration story for existing files; a versioned line format is one way to make such a change safe.
+
+#### Open: invariant coverage
+
+The invariant companion registers an empty installer because no relation can be checked without creating the id as a side effect. A future invariant could compare a re-read of the persisted file against the memoized id at a safe observation point.

 # @deepseek-ai/dsh-anonymous-user-id
 
 [English](README.md) | 中文
 
-会话遥测、直接反馈确认与 DeepSeek 提供方请求共用的匿名身份。`getOrCreateAnonymousUserId()` 返回一个限定于单个 harness home 的随机 UUID v4，并以裸行形式持久化到 `$DSH_HOME/.anonymous-user-id`（未设置 `DSH_HOME` 时为 `~/.dsh/.anonymous-user-id`）。OpenTelemetry 后端将其作为 Resource 的 `user.id` 上报；`/feedback` 在确认文本中包含同一个值；`dsh-llm-deepseek` 则通过 `x-deepseek-harness-user-id` 发送该值，使接收系统无需独立生成身份即可关联记录。
+## 概述
 
-该身份绝不从 hostname、网络地址、git remote 或其他可用于识别身份的来源派生。删除 `.anonymous-user-id` 后，下次启动进程时会重置身份。不同 harness home 拥有不同身份。
+每个 harness home 都会获得一个匿名 id，遥测、反馈与 DeepSeek 请求会把它附加到各自的记录上，让接收系统无需了解用户身份即可判断记录来自同一套安装。该 id 是存储在 `$DSH_HOME/.anonymous-user-id`（默认 `~/.dsh`）中的随机 UUID；它会在这些功能之一首次运行时自动出现，跨重启保持稳定，删除文件后会重新生成。不同 harness home 永远不会共享同一个 id，其中也不包含任何机器或账户信息。当你希望关联来自同一套安装、且不依赖账户的记录时使用它；它无法关联不同 home 之间的记录。
 
-## 存储约定
+## 目录
 
-读写采用同步方式，因为启动时构造遥测和直接执行命令都需要使用同一个 API。结果在进程生命周期内按解析后的文件路径缓存。首个写入方采用独占创建；并发竞争中失败的一方会采用已持久化的胜出值。损坏的文件会被替换。持久化采用 best-effort，因此即使 home 不可写，系统仍会返回进程本地 UUID，而不会阻塞遥测或反馈。

-## 组合
+-----
 
-本包是共享库，并非 Cordis 插件。消费方直接导入 `getOrCreateAnonymousUserId()`。其不变式伴生插件刻意留空，因为本包既不拥有事件流，也不拥有任何可以在不触发创建身份这一副作用的情况下检查的公开可变关系。`DSH_TELEMETRY_DISABLED` 只会停止遥测导出，不会禁止直接反馈确认或 DeepSeek 提供方标头。
+<a id="use-this-package"></a>
+## 使用本包
 
+当你希望本机安装外发的记录能被识别为来自同一个 harness home——遥测、反馈与 DeepSeek 请求都携带同一个共享 id——本包就是提供它的地方。无需安装或配置任何东西：id 会自动出现，已随附的反馈、遥测与 DeepSeek 功能已经在使用它。不要用它来识别用户，也不要用它关联不同 home 之间的记录；它是匿名的且限定于单个 home。
+
+### 该 id 能为你做什么
+
+你的安装外发的三类内容携带同一个 id，因此记录在它们之间可以相互对应：
+
+- **会话遥测**——你的遥测导出会以 `user.id` Resource 属性携带该 id，采集器因此可以按安装分组记录。
+- **反馈**——每条反馈确认都会指名记录该反馈的匿名安装。
+- **DeepSeek 请求**——每次提供方请求都会携带 `x-deepseek-harness-user-id` 标头，因此可以按安装归因用量。
+
+### 查看与重置 id
+
+该 id 存放在 `$DSH_HOME/.anonymous-user-id`（默认 `~/.dsh`）中，是一个纯 UUID 文本文件。删除该文件即可在下次启动时获得全新 id；正在运行的进程在退出前会一直保留当前 id。不同 harness home 各自保留独立 id，值中永远不会包含任何机器或账户信息。
+
+### 在自己的包中使用
+
+当你构建的功能需要共享该安装的匿名 id 时，导入该值并复用一次即可——遥测、反馈与 DeepSeek 已经在使用同一个 id，因此你的记录能与它们相互对应：
+
+```ts
+import { getOrCreateAnonymousUserId } from '@deepseek-ai/dsh-anonymous-user-id'
+
+const userId = getOrCreateAnonymousUserId() // stable for the process lifetime
+```
+
+该值在进程内保持稳定，并与内置功能使用的值一致；只有当文件被删除、后续启动生成替代值时才会改变。即使 home 目录不可写，该值在本次运行中依然可用，记录因此不会中断。

+
+本节解释本包背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+- **随机生成，绝不派生。** id 来自 `crypto.randomUUID()`；绝不从 hostname、网络地址、git remote 或任何其他可识别来源派生，因此匿名性是生成过程的属性。
+- **同步且记忆化。** 一个进程只触碰一次磁盘：读写都是同步的，结果按解析后的文件路径记忆化。
+- **Best-effort 持久化。** 写入失败仍会为本次运行返回可用 id，遥测与反馈因此不会因 home 不可写而阻塞。
+- **库而非插件。** 没有 Cordis 插件入口或配置；不变式伴生插件安装空安装器，因为本包不拥有任何事件流或公开可变关系，无法在不产生创建 id 这一副作用的情况下比较。

+
+### 存储约定
+
+文件是名为 `ANONYMOUS_USER_ID_FILE_NAME` 的裸 UUID 行，读取时按 UUID 模式校验。首个写入方使用独占创建（`wx`）；并发落败方重新读取并采用胜出方的值。损坏或不可读的文件会落入生成并覆盖的路径。记忆化按解析后的文件路径为键，因此不同 home 永远不会共享 id。

 # interaction/ — the human-collaboration plane
 
 English | [中文](README.zh.md)
 
-The services and plugins through which a human collaborates with a running agent — questions, approvals, permission presets, commands. These are **product** packages: real interfaces a person drives.
+## Summary
+
+The `interaction/` group is where a human collaborates with a running agent. It provides the slash-command plane users type into, the one-shot approval decisions behind sensitive actions, named permission presets that bundle sandbox mode with an approval policy, and the question/answer service an agent pauses on when it needs a human decision. All five packages are product packages — the real interfaces a person drives — and the product `dsh` CLI composes them directly. Interactive applications drive the command, approval, and question interfaces directly, while automation uses the ACP transport. The subsystem references own the exhaustive contracts; this map points at each package and its neighbors.

 # @deepseek-ai/dsh-commands

-Plugin-owned human-command registry consumed by interactive UI adapters. The [plugin command registration Agent Note](../../../.agents/notes/implemented/feature/2026-07-19-plugin-command-registration.md) owns the boundary and dispatch contract.
+## Summary
 
-## Service contract
+`dsh-commands` lets a user type `/command [input]` in an interactive Harness UI and run it directly against the receiving agent without creating a model message. Plugins register commands with a name, description, optional input hint and image-acceptance flag, and an abortable handler; interactive adapters discover and dispatch them per agent. A command-producing plugin mounted under an agent's context can register an exact agent-scoped command that shadows the global one of the same name. Each command run is recorded in the session log, and its result is rendered by the adapter, never entering model history. Slash commands ship with the `dsh` CLI and the Web client.
 
-`ctx.commands.register(definition)` registers one lowercase command name, description, optional unstructured-input descriptor (`hint` plus an `images` flag declaring whether composer image attachments may accompany an invocation), optional `recordInput` policy, and abortable handler. `recordInput` defaults to true; a command whose authoritative domain event owns the payload sets it to false so `command/run` omits `args` instead of duplicating the input. A registered command is available to every composed command adapter; a plugin that is incompatible with a deployment does not register there. A plain-context registration is global. A command-producing plugin mounted beneath `agent.ctx` declares its own `commands` injection and creates an exact agent-scoped definition; it shadows a global definition with the same name. This child-injection shape preserves the agent scope without making the core agent loop depend on a UI service. Duplicate names within one layer fail during registration. Every disposer is the exact Cordis effect disposer, and registration or removal notifies every `commands/change` observer so live adapters can refresh discovery; observer failures are logged and cannot veto the registry mutation or starve later observers.
+## Table of Contents
 
-`list(agent)` returns immutable, name-sorted descriptors after scoped shadowing (the descriptor carries `input.images` so composers can refuse image submissions to non-declaring commands before dispatch). `find(agent, name)` returns the corresponding definition. `execute(agent, line, images, signal)` uses `parseCommand()` and runs only a known command, returning the settled `CommandExecution` (the normalized result plus the lifecycle pairing `commandId`) or `undefined` for invalid syntax or unknown names. `images` carries the submission's base64-encoded composer images (`EncodedImageAttachment` from `@deepseek-ai/dsh-attachment/types`); the executor enforces the declaration — images sent to a non-declaring command, an absent `attachments` store, or an exceeded batch limit each settle as an error result before the handler runs, and a rejected batch publishes no durable object. An admitted batch is committed through `admitEncodedImages` and handed to the handler as frozen ordered `ImageBlock`s on `invocation.attachments`; the handler owns their model-visible use and returns an error when its grammar cannot use them, so the dispatching composer keeps the originals. A resolved command's lifecycle is logged on the receiving agent's session as the log-only pair `command/run` (before the handler, with a minted `commandId`, the parser's structured name, the issuing `CommandSource`, and `args` unless `recordInput` is false) and `command/done` (at settlement, with the outcome kind and verbatim text; a successful result may also name an earlier non-command authoritative domain event through `sourceEventSeq`; a thrown or aborted handler settles as `kind: 'error'`). Admission misses log nothing. Both are direct standalone appends on the receiving agent's session: no turn wraps them, and persistence drains them through ordinary checkpoints and teardown.

-`parseCommand()` recognizes a slash at byte zero, a lowercase name containing letters, digits, `_`, or `-`, and either end-of-input or whitespace. It returns every byte after the name as `rawInput`, including separator whitespace; consumers own their command-specific grammar and may normalize only what that grammar permits.
+-----
 
-Handlers return `success` or `error` plus optional UI text. A successful handler may also return `sourceEventSeq` when an earlier domain event owns a richer presentation; the lifecycle invariant requires that reference to be a prior non-command event in the same session. Results are rendered directly by the adapter and never enter model history. The registry never submits `rawInput` to the agent implicitly; a command producer may explicitly schedule model-visible work through the receiving `Agent`, in which case that producer owns the resulting message contract. The registry races handler completion against the supplied abort signal, but an uncooperative handler may continue its own external side effects after the caller stops awaiting it.

-## Composition
+Compose this service when an interactive UI should let users drive agent-side behavior with slash commands instead of model prompts. UI-less demo spines and ACP automation provide no command adapter and do not need it.
 
-The shipped `dsh` base mounts this service and the Web client dispatches through it. UI-less demo spines and ACP automation do not provide a command adapter. Custom interactive compositions and command producers mount `@deepseek-ai/dsh-commands` explicitly.
+### Registering a command
 
+A plugin registers a command with `ctx.commands.register()`: a lowercase name, a description shown in discovery, an optional `input` hint, and a handler that runs against the receiving agent.
+
+```text
+ctx.commands.register({
+  name: 'plan',
+  description: 'Enter plan mode',
+  input: { hint: '<message>' },
+  handler: ({ agent, rawInput }) => {
+    // Runs directly against the agent; no model message is created.
+    return { kind: 'success', text: 'plan mode selected' }
+  },
+})
+```
+
+The handler returns `success` or `error` plus optional UI text that the adapter renders. `recordInput` defaults to true; a command whose own authoritative domain event already carries the payload sets it to false so the session log does not duplicate the input. Registering the same name twice in one scope throws.
+
+### Command syntax
+
+A command line starts with a slash at byte zero, a lowercase name containing letters, digits, `_` or `-`, and then either end-of-input or whitespace. Everything after the name — including separator whitespace — is the command's `rawInput`, and the command owns its own grammar for it. Lines that are not syntactically a command, or that name an unknown command, are rejected by the adapter instead of becoming a model prompt.
+
+### Agent-scoped commands
+
+A plain registration is global. A command-producing plugin mounted beneath an agent's own context declares its `commands` injection and registers an exact agent-scoped command, which shadows the global definition of the same name for that agent only.
+
+### Image attachments
+
+A command may declare `input.images` to accept composer image attachments. The executor enforces the declaration: images sent to a non-declaring command, an absent attachment store, or an over-limit batch each settle as an error before the handler runs. Admitted images reach the handler as frozen ordered `ImageBlock`s on `invocation.attachments`, and the handler owns their model-visible use — the registry never schedules them itself.
+
+### Dispatching from an adapter
+
+An interactive adapter calls `execute(agent, line, images, signal)` with the exact receiving agent, the full command line, and the submission's images. It returns the settled `CommandExecution` — the normalized result plus its lifecycle `commandId` — or `undefined` for invalid syntax or an unknown name. `list(agent)` and `find(agent, name)` serve discovery after agent-scoped shadowing.
+
+### Cancellation
+
+The caller's abort signal stops the registry from awaiting a handler; a handler that ignores the signal may continue its own external side effects after the caller stops waiting. A cancelled or thrown handler settles as a `command/done` error in the log.

+The observable behavior is covered in [Use this package](#use-this-package); this section explains how the registry is built and where its contracts live.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | `CommandRuntime` service: registration, scoping, dispatch, lifecycle events |
+| [`src/types.ts`](src/types.ts) | Command definition, descriptor, execution, and result types |
+| [`src/brand.ts`](src/brand.ts) | `CommandId` brand for lifecycle pairing ids |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion pairing `command/run` with `command/done` per session log |
+
+### Lifecycle events
+
+`execute()` mints a `commandId`, appends `command/run` before the handler runs, and appends `command/done` at settlement with the outcome kind and verbatim text; the exact payload fields live in [`src/index.ts`](src/index.ts). A successful result may name an earlier non-command authoritative domain event through `sourceEventSeq`; a thrown or aborted handler settles as `kind: 'error'`. Both events are direct standalone log-only appends: no turn wraps them, and persistence drains them at ordinary checkpoints and teardown. Admission misses (invalid syntax or unknown name) log nothing.
+
+### Scoping
+
+Registrations live in global and agent-scoped layers merged per agent via `ScopedLayers`. The child-injection shape — a command-producing plugin mounted beneath `agent.ctx` declares its own `commands` injection — preserves agent scope without making the core agent loop depend on a UI service. Duplicate names within one layer fail during registration, and registration or removal notifies every `commands/change` observer so live adapters can refresh discovery; observer failures are logged and cannot veto the mutation or starve later observers.
+
+### Image admission
+
+Image enforcement happens in the executor, not the composer: an admitted batch is committed through `admitEncodedImages` against the `attachments` store, a rejected batch publishes no durable object, and cancellation is honored before the handler runs so a retrying caller never duplicates state. Handlers that cannot use the images return an error, so the dispatching composer keeps the originals.

-由插件负责、供交互式 UI 适配器使用的面向用户命令注册表。[插件命令注册 Agent Note](../../../.agents/notes/implemented/feature/2026-07-19-plugin-command-registration.zh.md)定义了其边界与分发约定。
+## 概述
 
-## 服务约定
+`dsh-commands` 让用户能在交互式 Harness UI 中输入 `/command [input]`，并直接针对接收命令的 agent（智能体）执行，不产生模型消息。插件注册命令时提供名称、描述、可选的输入提示与图片接受标志，以及可中止的处理器；交互式适配器按 agent 发现并分派这些命令。挂载在 agent 上下文之下的命令生产插件可以注册精确限定到该 agent 的命令，它会遮蔽同名的全局定义。每次命令执行都会记录在接收 agent 的会话日志中，结果由适配器渲染，绝不进入模型历史。斜杠命令随 `dsh` CLI 与 Web 客户端一起提供。
 
-`ctx.commands.register(definition)` 注册一个小写命令名称、描述、可选的非结构化输入描述符（`hint`，以及声明调用是否可携带 composer 图片附件的 `images` 标志）、可选的 `recordInput` 策略，以及可中止的处理器。`recordInput` 默认为 true；若载荷由命令的权威领域事件持有，该命令会将 `recordInput` 设为 false，让 `command/run` 省略 `args`，避免重复记录输入。每个已注册命令都可供所有已组合的命令适配器使用；与某项部署不兼容的插件不会在此注册。普通上下文中的注册全局生效。在 `agent.ctx` 下挂载的命令生产插件会声明自身的 `commands` 注入，并创建精确限定到该 agent（智能体）的定义；该定义会遮蔽同名的全局定义。这种子级注入形态保留了 agent 作用域，同时不会让核心 agent loop（智能体循环）依赖 UI 服务。同一层中的名称重复会在注册时失败。每个 disposer 都是 Cordis effect 返回的确切 disposer；注册或移除命令时，系统会通知每个 `commands/change` 观察者，使运行中的适配器能够刷新发现结果。观察者失败会写入日志，既不能否决注册表变更，也不能阻止后续观察者运行。
+## 目录
 
-`list(agent)` 在应用作用域遮蔽后，返回按名称排序的不可变描述符（描述符携带 `input.images`，使 composer 能在分发前就拒绝把图片提交给未声明的命令）。`find(agent, name)` 返回相应定义。`execute(agent, line, images, signal)` 使用 `parseCommand()`，且只运行已知命令，返回已结算的 `CommandExecution`（规范化结果加生命周期配对 `commandId`）；语法无效或名称未知时返回 `undefined`。`images` 携带本次提交的 base64 编码 composer 图片（来自 `@deepseek-ai/dsh-attachment/types` 的 `EncodedImageAttachment`）；执行器负责声明的强制执行：把图片发给未声明的命令、`attachments` 存储缺失、或批量超出限制，都会在处理器运行前以错误结果结算，被拒绝的批量不会发布任何持久化对象。通过准入的批量经 `admitEncodedImages` 提交，并以冻结的有序 `ImageBlock` 数组挂在 `invocation.attachments` 上交给处理器；处理器负责它们的模型可见用途，当其语法无法使用这些图片时返回错误，使分发方 composer 保留原件。已解析命令的生命周期会以 log-only 事件对的形式记录在接收 agent 的会话日志中：`command/run`（进入处理器前记录，携带新生成的 `commandId`、解析器的结构化名称、发起方 `CommandSource`，以及 `args`（`recordInput` 为 false 时省略））与 `command/done`（结算时记录，携带结果类型与原样文本；成功结果还可通过 `sourceEventSeq` 指向更早的一条非命令权威领域事件；处理器抛出或被中止时以 `kind: 'error'` 结算）。未通过准入的输入不记录任何事件。两者都直接独立追加到接收 agent 的会话中：没有轮次包裹它们，持久化机制会在常规检查点和销毁期间排空这些事件。

-`parseCommand()` 识别位于第 0 字节的斜杠、由小写字母、数字、`_` 或 `-` 构成的名称，以及名称后紧接输入末尾或空白的形式。它将名称后的每个字节作为 `rawInput` 返回，其中包括分隔空白；消费方负责各命令专用的语法，只能执行该语法允许的规范化。
+-----
 
-处理器返回 `success` 或 `error`，并可附带 UI 文本。若更丰富的呈现由一条更早的领域事件持有，成功的处理器还可返回 `sourceEventSeq`；生命周期不变量要求该引用指向同一会话中更早的一条非命令事件。适配器直接渲染结果，结果绝不进入模型历史。注册表绝不会隐式地把 `rawInput` 提交给 agent；命令生产方可以通过接收命令的 `Agent` 显式安排模型可见工作，此时该生产方负责由此产生的消息约定。注册表会同时等待处理器完成和所提供的中止信号，以先发生者为准，但不响应中止的处理器可能在调用方停止等待后继续产生自身的外部副作用。

+## 使用本包
 
-## 组合
+当交互式 UI 希望用户用斜杠命令而非模型提示词驱动 agent 侧行为时，组合此服务。无 UI 的演示主干和 ACP（Agent Client Protocol）自动化不提供命令适配器，也不需要它。
 
-随产品交付的 `dsh` 基础组合会挂载此服务，Web 客户端通过它分派命令。无 UI 的演示主干和 ACP（Agent Client Protocol）自动化不提供命令适配器。自定义交互式组合与命令生产方会显式挂载 `@deepseek-ai/dsh-commands`。
+### 注册命令
 
+插件用 `ctx.commands.register()` 注册命令：小写名称、在发现界面中展示的描述、可选的 `input` 提示，以及针对接收 agent 运行的处理器。
+
+```text
+ctx.commands.register({
+  name: 'plan',
+  description: 'Enter plan mode',
+  input: { hint: '<message>' },
+  handler: ({ agent, rawInput }) => {
+    // Runs directly against the agent; no model message is created.
+    return { kind: 'success', text: 'plan mode selected' }
+  },
+})
+```
+
+处理器返回 `success` 或 `error`，并可附带由适配器渲染的 UI 文本。`recordInput` 默认为 true；若载荷由命令自己的权威领域事件持有，命令会将 `recordInput` 设为 false，避免会话日志重复记录该输入。同一作用域内重复注册同名命令会抛出异常。
+
+### 命令语法
+
+命令行的第 0 字节必须是斜杠，随后是小写名称（可含字母、数字、`_` 或 `-`），再之后是输入末尾或空白。名称之后的每个字节——包括分隔空白——都是该命令的 `rawInput`，命令自己拥有其专属语法。不符合命令语法、或名称未知的行会被适配器拒绝，而不是变成模型提示词。
+
+### 限定到 agent 的命令
+
+普通注册全局生效。挂载在 agent 自身上下文之下的命令生产插件会声明 `commands` 注入，并注册精确限定到该 agent 的命令；该定义只对这个 agent 遮蔽同名的全局定义。
+
+### 图片附件
+
+命令可以声明 `input.images` 以接受 composer 图片附件。执行器负责声明的强制执行：把图片发给未声明的命令、附件存储缺失或批量超出限制，都会在处理器运行前以错误结果结算。通过准入的图片以冻结的有序 `ImageBlock` 数组挂在 `invocation.attachments` 上交给处理器，其模型可见用途由处理器负责——注册表本身绝不定时调度它们。
+
+### 从适配器分派
+
+交互式适配器调用 `execute(agent, line, images, signal)`，传入确切的接收 agent、完整命令行与本次提交的图片。它返回已结算的 `CommandExecution`——规范化结果加生命周期配对 `commandId`——语法无效或名称未知时返回 `undefined`。`list(agent)` 与 `find(agent, name)` 在应用 agent 作用域遮蔽后服务发现。
+
+### 取消
+
+调用方的中止信号会让注册表停止等待处理器；无视信号的处理器可能在调用方停止等待后继续产生自身的外部副作用。被取消或抛异常的处理器在日志中以 `command/done` 错误结算。

 # @deepseek-ai/dsh-permission-presets
 
 English | [中文](README.zh.md)
 
-User-facing permission presets through `ctx.permissionPresets` ([`PermissionPresetService`](src/index.ts)). Each configured name bundles `sandbox/mode` with `approval/policy`; the defaults are `workspace-write` (`workspace-write` + `ask`) and `danger-full-access` (`danger-full-access` + `never`). UI adapters may expose the table as one selector, while sandbox execution and approval continue to consume their own knobs.
+## Summary
 
-`set(session, name)` records a changed selection in a log-only `permissionPresets/preset` event, then calls each knob's setter only when its effective value changes. The selection event precedes the knob events and preserves user intent when presets share a bundle; a net-zero selection appends nothing. `current(events)` prefers a still-matching recorded selection, then the first matching table entry, and otherwise returns `custom`. Clients may display `custom` as the current value, but cannot select it.
+`dsh-permission-presets` gives a deployment one user-facing Permissions selector that bundles two independent enforcement knobs — the sandbox mode and the approval policy — into named presets. Selecting a preset applies the sandbox mode and approval policy together, while each knob keeps its own value, so sandbox execution, approval, prompt narration, and replay each read their own setting. The default table ships `workspace-write` (workspace-write + ask) and `danger-full-access` (danger-full-access + never); a knob combination matching no preset reads back as the derived `custom`, which clients may display but never select. The service also owns the `permission` settings namespace whose default applies only when a later session is created, and two optional children — a `permissions` session projection and the `/permission` command — expose the same surface to the Web client. Mounting it requires a confining bash executor and the approval service; it owns no enforcement itself.
 
-The service owns the `permissionPresets` Settings namespace. Its `defaultPreset` is the default for future sessions: the composition entry uses `Config.defaultPreset`, or infers the preset matching the composed sandbox and approval defaults when omitted. A committed Settings change is read when the next session is created; creation pins `permissionPresets/preset`, `sandbox/mode`, and `approval/policy` into that session, so later changes never alter an existing session. A resumed seed, including an explicitly empty one marked by `session/end-seed`, preserves its effective permission and receives only missing durable facts rather than the latest user default. Mounting the service also sweeps already-live sessions, so an HMR replacement pins any session created while the plugin was absent.
+## Table of Contents
 
-The service requires a confining `ctx.shell` executor and `ctx.approval`. A table entry named `custom` throws at load. When composition defaults match no preset, the plugin requires an explicit `defaultPreset`; an independently constructed zero-event session may still derive `custom`. See the [sandbox switching design](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md).

-Two optional children ship the product surfaces over the same service: a `permissions` session-projection unit (`src/types.ts` declares the key; the unit folds the three whole-value knob events and views the select — table options plus a current-only `custom` — over the composition defaults) and the `/permissionPresets` command (bare invocation reports the current preset and the table; a preset argument switches through `set`). Each child activates only when its registry (`ctx.sessionProjections` / `ctx.commands`) is composed.

+## Use this package
+
+Choose this service when a deployment wants to offer users one Permissions selector instead of separate sandbox and approval controls. It bundles the knobs; execution and approval keep their own values, so removing the package later leaves the last selection in effect.
+
+### Configuring presets
+
+The plugin config defines the preset table and the default for fresh sessions. Each preset name bundles one sandbox mode with one approval policy; `name` and `description` are optional client presentation.
+
+```yaml
+- name: '@deepseek-ai/dsh-permission-presets'
+  config:
+    presets:
+      workspace-write:
+        sandbox: workspace-write
+        approval: ask
+      danger-full-access:
+        sandbox: danger-full-access
+        approval: never
+    defaultPreset: workspace-write
+```
+
+| Field | Default | Meaning |
+|---|---|---|
+| `presets` | `workspace-write`, `danger-full-access` | Table of preset name → sandbox/approval bundle |
+| `defaultPreset` | inferred | Preset pinned into fresh sessions; required when composition defaults match no preset |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-permission-presets) is the exhaustive source for every accepted field and its JSDoc. The name `custom` is reserved for the derived not-a-preset state and cannot name a table entry. Mounting requires a confining bash executor (one that reports a `sandboxMode`) and the approval service.
+
+### Switching presets
+
+Switching to a preset changes only the knobs whose effective value differs; selecting the preset already in effect changes nothing. The current value resolves as the still-matching last recorded selection, else the first matching table entry, else `custom`. Users switch through the `/permission` command: a bare invocation reports the current preset and the available table, and a preset argument switches to it.
+
+### What users see
+
+Clients render the select with every switchable preset in table order, plus `custom` shown exactly while it is current. `custom` is display-only — callers can switch away from an unmatched knob combination but cannot select or persist a named custom preset through this service.
+
+### Session defaults
+
+The `permission` settings namespace holds `defaultPreset` for future sessions: session creation reads it, applies it to the sandbox mode and approval policy, and records the applied preset as a `permission/preset` selection. Later settings changes never alter an existing session. A resumed seed, including an explicitly empty one marked by `session/end-seed`, preserves its effective permission and receives only missing durable facts rather than the latest user default.

The selection event precedes the knob events so user intent survives when two presets share a bundle; a net-zero selection appends nothing.
+
+### Read side and `custom`
+
+`current(events)` folds the three whole-value knob events over the composition defaults (`ctx.shell.sandboxMode` and the approval config). A still-matching last selection wins shared-bundle ties; otherwise the first table match wins; otherwise the derived `CUSTOM_PRESET` is returned. The `permissions` projection unit applies the same fold one event at a time and serves the select to clients.
+
+### Session pinning and blank reuse
+
+Mounting pins every live and future session: a genuinely fresh session gains the default preset and both knob facts, while seeded or partially initialized sessions keep their effective knob values and gain only missing durable facts.
+
+### Optional children

+The `permissions` projection unit registers only when a `ctx.sessionProjections` registry is composed; the `/permission` command registers only when a `ctx.commands` registry is composed. Headless assemblies without either registry stay unaffected.

 [English](README.md) | 中文
 
-通过 `ctx.permissionPresets`（[`PermissionPresetService`](src/index.ts)）提供面向用户的权限预设。每个配置名称都会将 `sandbox/mode` 与 `approval/policy` 组成一组；默认项为 `workspace-write`（`workspace-write` + `ask`）和 `danger-full-access`（`danger-full-access` + `never`）。UI 适配器可以将该表作为单个选择器公开，而沙箱执行与审批仍分别消费各自的调节项。
+## 概述
 
-`set(session, name)` 会先在仅写日志的 `permissionPresets/preset` 事件中记录已变更的选择，再仅对实际值发生变化的调节项调用 setter。选择事件先于调节项事件，并在多个预设共享同一组取值时保留用户意图；净变化为零的选择不会追加任何内容。`current(events)` 优先返回仍与当前调节项匹配的已记录选择，其次返回表中第一个匹配项，否则返回 `custom`。客户端可以把 `custom` 显示为当前值，但不能选择它。
+`dsh-permission-presets` 为部署提供一个面向用户的 Permissions 选择器，把两个独立的执行旋钮——沙箱模式与审批策略——捆绑为具名预设。选择预设会同时应用沙箱模式与审批策略，而每个旋钮各自保留自己的值，因此沙箱执行、审批、提示词叙述与回放都读取各自的设置。默认表提供 `workspace-write`（workspace-write ＋ ask）与 `danger-full-access`（danger-full-access ＋ never）；不匹配任何预设的旋钮组合会读回推导出的 `custom`，客户端可以显示它，但不能选择它。该服务还拥有 `permission` 设置命名空间，其默认值只在之后创建会话时生效；两个可选子功能——`permissions` 会话投影单元与 `/permission` 命令——向 Web 客户端暴露同一表面。挂载它需要具有约束能力的 bash 执行器与审批服务；它自身不拥有任何执行权。
 
-该服务拥有 `permissionPresets` Settings namespace。其 `defaultPreset` 是未来会话的默认值：组合项使用 `Config.defaultPreset`；省略时，则推断与组合后的沙箱和审批默认值匹配的 preset。已提交的 Settings 变更会在下一个会话创建时读取；创建过程将 `permissionPresets/preset`、`sandbox/mode` 和 `approval/policy` 固定到该会话中，因此后续变更绝不会改变现有会话。恢复的 seed，包括由 `session/end-seed` 标记的显式空 seed，都会保留其有效权限，只补齐缺失的持久事实，而不会采用最新的用户默认值。挂载服务时还会遍历所有已存活会话，因此 HMR（热模块替换）会固定插件缺席期间创建的所有会话。
+## 目录
 
-该服务要求存在具有约束能力的 `ctx.shell` 执行器和 `ctx.approval`。表中名为 `custom` 的条目会在加载时抛出异常。当组合默认值与任何 preset 都不匹配时，插件要求显式配置 `defaultPreset`；独立构造的零事件会话仍可能推导出 `custom`。详见[沙箱切换设计](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.zh.md)。

+## 使用本包
+
+当部署希望向用户提供一个 Permissions 选择器、而非分离的沙箱与审批控件时，选择此服务。它捆绑旋钮；执行与审批各自保留自己的取值，因此以后移除本包，最后一次取值依然生效。
+
+### 配置预设
+
+插件配置定义预设表与新会话的默认值。每个预设名称把一个沙箱模式与一个审批策略捆绑为一组；`name` 与 `description` 是可选的客户端呈现。
+
+```yaml
+- name: '@deepseek-ai/dsh-permission-presets'
+  config:
+    presets:
+      workspace-write:
+        sandbox: workspace-write
+        approval: ask
+      danger-full-access:
+        sandbox: danger-full-access
+        approval: never
+    defaultPreset: workspace-write
+```
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `presets` | `workspace-write`、`danger-full-access` | 预设名称 → 沙箱／审批捆绑的表 |
+| `defaultPreset` | 推断 | 固定到新会话的预设；组合默认值不匹配任何预设时必填 |
+
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-permission-presets)是每个受支持字段及其 JSDoc 的穷尽式真源。`custom` 这个名称保留给推导出的非预设状态，不能作为表条目。挂载需要具有约束能力的 bash 执行器（会报告 `sandboxMode` 的执行器）与审批服务。
+
+### 切换预设
+
+切换到某个预设只改变实际值不同的旋钮；再次选择当前已生效的预设不会产生任何变化。当前值解析顺序为：仍匹配的最近一次记录选择，其次表中第一个匹配项，否则为 `custom`。用户通过 `/permission` 命令切换：不带参数调用时报告当前预设与可用表，带预设参数时切换过去。
+
+### 用户看到什么
+
+客户端渲染选择器：按表顺序列出每个可切换预设，并在当前值为 `custom` 时将其附加在末尾。`custom` 仅供显示——调用方可以从不匹配的旋钮组合切换出去，但不能通过此服务选中或持久化一个具名 custom 预设。
+
+### 会话默认值
+
+`permission` 设置命名空间为未来会话持有 `defaultPreset`：创建会话时读取它，将其应用于沙箱模式与审批策略，并把应用的预设记录为一次 `permission/preset` 选择。之后的设置变更绝不会改变现有会话。恢复的 seed（包括由 `session/end-seed` 明确标记的空 seed）会保留其有效权限，并只接收缺失的持久事实，而不会接收最新用户默认值。

+### 读取侧与 `custom`
+
+`current(events)` 在组合默认值（`ctx.shell.sandboxMode` 与审批配置）之上折叠三个全量值旋钮事件。仍匹配的最近选择在共享捆绑时胜出；否则表中第一个匹配项胜出；否则返回推导出的 `CUSTOM_PRESET`。`permissions` 投影单元逐事件应用同一折叠，并向客户端提供选择器。
+
+### 会话固定与空白复用
+
+挂载时会固定所有存活与未来的会话：真正全新的会话获得默认预设与两个旋钮事实，而 seed 会话或部分初始化的会话保留其有效旋钮值，只补充缺失的持久事实。

-Model-facing `ask_user_question` tool over `ctx.userQuestions`. It lets the model ask the human a concise question when it needs confirmation, a choice, or missing information before continuing.
+## Summary
 
-## Tool
+`dsh-tool-ask-user` gives the model one tool — `ask_user_question` — for asking the human a concise question when it needs confirmation, a choice, or missing information before continuing. The tool pauses until the first scoped answerer accepts the request, then feeds that answer back into the agent loop as an ordinary tool result, so no loop mechanics change. The tool returns the canonical `{ answers: [...] }` shape, rendered as compact JSON text. It renders no UI itself and does not know how input is collected; the Web client contributes its answerer through Remote Events. A runtime-owned child agent cannot ask the user; it must include the unresolved question in its final result.
 
-`ask_user_question` accepts:
+## Table of Contents
 
-- `questions` — required non-empty array of question objects.
-- `id` — required stable id on each question, echoed in the answer.
-- `question` — required question text for each question.
-- `header` — optional short heading.
-- `options` — optional choices with `label` and `description`. If recommending a choice, put it first and append `(Recommended)` to that label.
-- `multi_select` — whether that question may return more than one selected option.

+- [Dev Note](#dev-note)
 
-The tool calls `ctx.userQuestions.ask()` and returns canonical `{ answers: [{ id, selected, custom? }] }`. `selected` contains option labels; `custom` carries a free-form answer, supplementing `selected` for a multi-select question and overriding it for a single-select question. The Native renderer preserves the compact JSON text shape `{ "answers": [{ "id": "...", "selected": ["..."], "custom": "..." }] }`.
+-----
 
-## Role
+<a id="use-this-package"></a>
+## Use this package
 
-This is the Consumer package for the user-questions seam. It does not render UI and does not know how input is collected; it only translates model arguments into `AskUserQuestionRequest` and returns the human answer to the agent loop.
+Compose this plugin wherever the model should be able to pause for a human decision: it provides the `ask_user_question` tool and needs the `ctx.userQuestions` seam with an answerer that accepts the scoped request. Without one, the tool call fails with an error instead of degrading.
 
+### When to call the tool
+
+The model calls `ask_user_question` when it needs confirmation, a choice, or missing information before proceeding. Send one or more questions, each with a stable `id` that is echoed in the answer; a recommended option goes first with `(Recommended)` appended to its label.
+
+```json
+{
+  "questions": [
+    {
+      "id": "cleanup",
+      "question": "Proceed with the destructive cleanup?",
+      "header": "Confirm",
+      "options": [
+        { "label": "Yes, delete them (Recommended)", "description": "Removes the three stale files." },
+        { "label": "No, keep them", "description": "Aborts the cleanup." }
+      ]
+    }
+  ]
+}
+```
+
+### What the model gets back
+
+The tool returns one answer object per question: `selected` holds the chosen option labels, and `custom` carries a free-form answer — supplementing `selected` for a multi-select question and overriding it for a single-select question. The Native renderer preserves the compact JSON text shape.
+
+```json
+{ "answers": [{ "id": "cleanup", "selected": ["Yes, delete them (Recommended)"] }] }
+```
+
+### When the call fails
+
+The tool call blocks until the human answers and cancels only through the turn's signal. No accepting answerer, an aborted call, or a caller that is not the exact live runtime root each settles as an error the model sees in the tool result — most notably, a live child agent owned by another agent is rejected (`DELEGATED_CALLER`) and must include the unresolved question or decision in its final result.

+## 概述
 
-## 工具
+`dsh-tool-ask-user` 为模型提供一个工具——`ask_user_question`——用于在需要确认、选择结果或缺失的信息才能继续时，向用户提出简明问题。工具会暂停，直到首个作用域 answerer 接受请求，然后把回答作为普通工具结果送回 agent loop（智能体循环），因此循环机制没有任何变化。工具返回规范的 `{ answers: [...] }` 结构，并以紧凑的 JSON 文本形式呈现。它自身不渲染 UI，也不了解输入的收集方式；Web Client 通过 Remote Events 提供 answerer。运行时中归属于其他 agent 的子级不能向用户提问；它必须在最终结果中包含尚未解决的问题。
 
-`ask_user_question` 接受以下参数：
+## 目录
 
-- `questions`：必填的非空问题对象数组。
-- `id`：每个问题必填的稳定 id，会原样包含在回答中。

-## 职责

+## 使用本包
 
-此包是用户交互 seam 的Consumer 包。它不渲染 UI，也不了解输入的收集方式；它只将模型参数转换为 `AskUserQuestionRequest`，并把用户回答返回给 agent loop（智能体循环）。
+凡模型应当能够暂停等待人类决定的场景，都可组合此插件：它提供 `ask_user_question` 工具，并且需要带有接受作用域请求的 answerer 的 `ctx.userQuestions` seam。没有 answerer 接受时，工具调用会以错误失败，而不是降级。
 
+### 何时调用该工具
+
+当模型需要确认、选择结果或缺失的信息才能继续时，调用 `ask_user_question`。发送一个或多个问题，每个问题携带稳定的 `id`（回答中会原样包含）；推荐选项放在首位，并在标签末尾追加 `(Recommended)`。
+
+```json
+{
+  "questions": [
+    {
+      "id": "cleanup",
+      "question": "Proceed with the destructive cleanup?",
+      "header": "Confirm",
+      "options": [
+        { "label": "Yes, delete them (Recommended)", "description": "Removes the three stale files." },
+        { "label": "No, keep them", "description": "Aborts the cleanup." }
+      ]
+    }
+  ]
+}
+```
+
+### 模型得到什么
+
+工具为每个问题返回一个回答对象：`selected` 保存选中的选项标签，`custom` 携带自由填写的回答——对多选题补充 `selected`，对单选题覆盖它。Native 渲染器保留紧凑的 JSON 文本形式。
+
+```json
+{ "answers": [{ "id": "cleanup", "selected": ["Yes, delete them (Recommended)"] }] }
+```
+
+### 调用何时失败
+
+工具调用会阻塞到用户作答，并且只能通过当前轮次的信号取消。没有 answerer 接受、调用被中止、或调用方不是确切的存活运行时根，都会以模型在工具结果中看到的错误结算——最值得注意的是，归属于另一个 agent 的存活子级会被拒绝（`DELEGATED_CALLER`），必须在最终结果中包含尚未解决的问题或决定。

 # @deepseek-ai/dsh-user-approval
 
 English | [中文](README.zh.md)
 
-Channel-neutral one-shot approval seam. `ctx.approval.request(req)` returns `allowed-once`, `rejected`, `cancelled`, or `unavailable`; missing or failing answerers fail closed, and a grant applies only to the requested action. Exact event signatures live in the generated region of [approval.md](../../../docs/subsystems/approval.md#cordis-surface).
+## Summary
 
-Each request must belong to an open agent turn. The service appends a paired `approval/asked` and `approval/decided` audit record, while the model sees only the resulting logged tool outcome. An aborted request resolves `cancelled`; an audit append that fails before commit rejects rather than returning an unlogged decision.
+`dsh-user-approval` lets a sensitive tool action pause for a one-shot allow/reject decision: `ctx.approval.request(req)` asks the composed answerers whether one specific action may proceed and returns `allowed-once`, `rejected`, `cancelled`, or `unavailable`. Missing, non-owning, or throwing answerers fail closed to `unavailable`, and a grant applies only to the requested action. A per-session policy — `ask` (the default) or `never` — decides what happens before any answerer runs: `ask` delegates to the composed answerers, `never` rejects every request deterministically without prompting anyone. Each request is recorded in the requesting session's audit log, and the model sees only the asking consumer's tool outcome plus the current policy in the runtime-context snapshot. UI channels provide human answerers; the ACP automation bridge answers for its own agents.
 
-Answerers are `approval/request` waterfall listeners. Return an outcome to answer for an owned agent or call `next()` to delegate. Agent-scoped listeners receive only that agent's requests; compose one terminal answerer per deployment because sibling listener order is not a policy priority mechanism. The ACP automation bridge supplies one-shot machine decisions for sessions it owns.
+## Table of Contents
 
-`ApprovalPolicy` is `'ask'` or `'never'`. The effective value is the last `approval/policy` event, falling back to config; `setApprovalPolicy()` is the write path. `'never'` rejects before interactive dispatch. Both policies contribute their complete current meaning to the cache-safe runtime-context snapshot.

-The tools pipeline routes `ask` decisions through this seam and fails closed when it is absent; the sandboxed bash tool also uses it for escalated retries. The ACP automation bridge answers calls for its own agents through the client's machine policy. Audit events remain log-only, so the model sees only the asking consumer's result. See the [approval-seam Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-approval-seam.md) and [sandbox Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md).

+<a id="use-this-package"></a>
+## Use this package
+
+Compose this service when sensitive tool actions should pause for a human or machine decision instead of running unconditionally. The tools pipeline and the sandboxed bash tool route their `ask` decisions through this seam and fail closed when it is absent, so interactive deployments mount it with at least one answerer.
+
+### Composing answerers
+
+Answerers are `approval/request` waterfall listeners: return an outcome to answer for an owned agent, or call `next()` to delegate. Agent-scoped listeners receive only that agent's requests, and a deployment composes one terminal answerer — sibling listener order is not a policy-priority mechanism. Without a terminal answerer, requests resolve `unavailable` and fail closed; the service itself never prompts a human.
+
+### Setting the policy
+
+The effective policy is the one set for the session, falling back to the configured default. `ask` (the default) delegates to the composed answerers; `never` rejects every request deterministically before interactive dispatch — the strict headless stance for CI and unattended runs.
+
+```yaml
+- name: '@deepseek-ai/dsh-user-approval'
+  config:
+    policy: ask
+```
+
+| Field | Default | Meaning |
+|---|---|---|
+| `policy` | `ask` | Default for sessions without an `approval/policy` override |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-user-approval) is the exhaustive source for every accepted field and its JSDoc. `setPolicy(agent, policy)` switches a live agent and queues a "changed by the user" message for its next model step; `setApprovalPolicy(session, policy)` is the direct durable write path used by session initialization.
+
+### Requesting a decision
+
+`request(req)` names the agent, tool, optional call id and reason, and an abort signal. It requires an open turn: an idle or between-turn caller throws before auditing anything. Aborting withdraws the question — the request settles `cancelled` and a late answer is discarded. A failure that prevents either audit append from committing rejects instead of returning an unlogged decision.
+
+### What the model and user see
+
+The model sees only the asking consumer's eventual tool outcome — allowed, rejected, cancelled, or unavailable — plus the current policy in the runtime-context snapshot; the audit events and the human permission UI are not model context. A `never` switch is announced to the model by a sourced user message, and both policies contribute their complete current meaning to the snapshot.

+
+The observable behavior is covered in [Use this package](#use-this-package); this section explains dispatch, policy enforcement, and the audit path.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | `ApprovalService`: request dispatch, policy fold and write path, runtime-context contribution |
+| [`src/types.ts`](src/types.ts) | `ApprovalRequestId` brand and outcome types |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion pairing `approval/asked` with `approval/decided` inside an open turn |
+
+### Dispatch
+
+`decide()` races the answerer waterfall against the request signal and contains every answerer failure: a throwing listener fails the question closed to `unavailable`, and a rogue non-vocabulary return is normalized to `unavailable`. The `never` policy is enforced inside the service before waterfall dispatch, so a listener registered later with `prepend` cannot bypass the deterministic rejection. The request must be turn-enclosed because the turn is the durable log's commit/replay boundary — a bare event between turns is indistinguishable from a crash tail.
+
+### Policy and the runtime-context snapshot
+
+The system-prompt contribution `approval:policy` states the complete current meaning of the effective policy — `ask` with its fail-closed consequence, or `never` with its non-escalation consequence — after retained history, so switching policy appends a new full snapshot instead of rewriting the stable request header. `setPolicy()` also injects a sourced user message announcing the change for the next step.
+
+### Audit
+
+`request()` appends `approval/asked` with the request identity and tool, then `approval/decided` with the closed outcome; the exact appended fields live in [`src/index.ts`](src/index.ts). Both are log-only; the invariant validates the pair by id within one open turn and the closed outcome vocabulary.

 [English](README.md) | 中文
 
-与通道无关的一次性审批 seam。`ctx.approval.request(req)` 返回 `allowed-once`、`rejected`、`cancelled` 或 `unavailable`；应答者缺失或失败时会以拒绝方式关闭，授权也只适用于所请求的操作。确切事件签名见 [approval.md](../../../docs/subsystems/approval.zh.md#cordis-surface) 的生成区块。
+## 概述
 
-每个请求都必须属于一个尚未结束的 agent（智能体）轮次。服务会追加一对 `approval/asked` 与 `approval/decided` 审计记录，而模型只会看到由此产生且已写入日志的工具结果。已中止的请求会解析为 `cancelled`；如果审计记录的追加在提交前失败，Promise 会被拒绝，而不会返回一项未记录的决定。
+`dsh-user-approval` 让敏感的工具操作暂停等待一次性的允许／拒绝决定：`ctx.approval.request(req)` 向已组合的应答者询问某个具体操作是否可以继续，并返回 `allowed-once`、`rejected`、`cancelled` 或 `unavailable`。应答者缺失、不负责或抛出异常时，请求以 `unavailable` 关闭；授权也只适用于所请求的操作。按会话策略——`ask`（默认）或 `never`——决定在任何应答者运行之前发生什么：`ask` 委托给已组合的应答者，`never` 确定性地拒绝每个请求，不提示任何人。每个请求都会记录在发起请求的会话审计日志中；模型只会看到发起请求的消费方的工具结果，以及运行时上下文快照中的当前策略。UI 通道提供人类应答者；ACP（Agent Client Protocol）自动化桥接层为其自有 agent 作答。
 
-应答者是 `approval/request` waterfall（瀑布式事件）监听器。要回答其负责的 agent 请求，请返回一个结果；否则调用 `next()` 委托。限定到 agent 的监听器只接收该 agent 的请求；每项部署应当组合一个最终应答者，因为同级监听器的顺序不是策略优先级机制。ACP（Agent Client Protocol）自动化桥接层为其负责的会话提供一次性机器决定。
+## 目录
 
-`ApprovalPolicy` 为 `'ask'` 或 `'never'`。实际值取最后一条 `approval/policy` 事件，并回退到配置；`setApprovalPolicy()` 是写入路径。`'never'` 会在交互式分发之前拒绝请求。两种策略都会将各自完整的当前含义贡献给缓存安全的运行时上下文快照。

+## 使用本包
+
+当敏感工具操作应当暂停等待人或机器的决定、而非无条件执行时，组合此服务。工具流水线与沙箱 bash 工具会通过此 seam 路由 `ask` 决定，并在该 seam 缺失时以拒绝方式关闭，因此交互式部署至少应组合一个应答者。
+
+### 组合应答者
+
+应答者是 `approval/request` waterfall（瀑布式事件）监听器：返回一个结果即为所负责的 agent 作答，否则调用 `next()` 委托。限定到 agent 的监听器只接收该 agent 的请求，且每项部署应组合一个最终应答者——同级监听器的顺序不是策略优先级机制。没有最终应答者时，请求解析为 `unavailable` 并以拒绝方式关闭；服务自身绝不会提示人类。
+
+### 设置策略
+
+有效策略取会话中已设置的策略，并回退到配置的默认值。`ask`（默认）委托给已组合的应答者；`never` 在交互式分发之前确定性地拒绝每个请求——这是 CI 与无人值守运行的严格无头姿态。
+
+```yaml
+- name: '@deepseek-ai/dsh-user-approval'
+  config:
+    policy: ask
+```
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `policy` | `ask` | 没有 `approval/policy` 覆盖的会话的默认策略 |
+
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-user-approval)是每个受支持字段及其 JSDoc 的穷尽式真源。`setPolicy(agent, policy)` 切换存活 agent 的策略，并为它的下一个模型步骤排队一条「由用户更改」消息；`setApprovalPolicy(session, policy)` 是会话初始化使用的直接持久写入路径。
+
+### 请求决定
+
+`request(req)` 指名 agent、工具、可选的调用 id 与原因，以及一个中止信号。它要求当前处于尚未结束的轮次中：空闲或在轮次之间调用会在审计前抛出异常。中止会撤回问题——请求以 `cancelled` 结算，迟到的回答被丢弃。若任一审计事件在提交前失败，请求会被拒绝，而不会返回一项未记录的决定。
+
+### 模型与用户看到什么
+
+模型只会看到发起请求的消费方最终给出的工具结果——允许、拒绝、取消或不可用——以及运行时上下文快照中的当前策略；审计事件与面向人类的权限 UI 不属于模型上下文。`never` 切换会以一条带来源的用户消息告知模型，两种策略都会把各自的完整当前含义贡献给快照。

 English | [中文](README.zh.md)
 
-This family gives long-running tools one owner-isolated background-job protocol for observation, cancellation, waiting, and completion notices.
+## Summary
+
+The jobs group is the background-work capability family: tools that run long work register it as a job, and the owning agent can read, wait on, list, and cancel it without blocking its own turn. Jobs belong to the agent session that started them, so one agent never sees another's work, and completion is delivered to the owning agent in-session instead of polled. The group splits into the registry contract (`jobs`), its process-local storage (`jobs-local`), and the model-facing control tools with completion notices (`tool-jobs`).

 [English](README.md) | 中文
 
-本家族为长时间运行的工具提供一套按所有者隔离的后台任务协议，用于观察、取消、等待和完成通知。
+## 概述
+
+jobs 组是后台工作能力家族：运行长时间工作的工具把工作注册为任务，拥有它的 agent 可以在不阻塞自身轮次的情况下读取、等待、列出或取消任务。任务属于启动它的 agent 会话，因此一个 agent 永远不会看到另一个 agent 的工作；任务完成时以会话内通知送达给拥有它的 agent，无需轮询。本组拆分为注册表约定（`jobs`）、其进程本地存储（`jobs-local`）以及带完成通知的模型侧控制工具（`tool-jobs`）。

 # @deepseek-ai/dsh-jobs-local
 
 English | [中文](README.zh.md)
 
-Process-local implementation of the [`@deepseek-ai/dsh-jobs`](../jobs/README.md) registry contract: `LocalJobRegistry` keeps every record in memory, issues per-kind `<kind>-N` ids, and hands out fresh snapshots, never live state. Load it as a plugin and it registers as `ctx.jobs`.
+## Summary
 
-## Admission
+`dsh-jobs-local` runs background jobs inside the harness process: work keeps running while the agent moves on, and the owning agent can read, wait on, list, and cancel it, with completion delivered as an in-session notice when `dsh-tool-jobs` is also mounted. It implements the `dsh-jobs` contract with in-memory records handed out as fresh snapshots, never live state. A per-owner concurrency limit (default 10) bounds how many jobs one agent can have running or stopping at once; jobs die with the harness process and are not durable across restarts.
 
-`maxConcurrentJobsPerOwner` is a positive safe integer and defaults to `10`. Before invoking a producer, `start()` counts the exact owner's `running` and `stopping` records; all unowned jobs share one separate service bucket. Terminal history does not occupy capacity, and only producer `done` settlement releases a stopping job's place.
+## Table of Contents
 
-At capacity, `start()` fails before producer execution and id allocation with an error that names the limit and tells the model to use `job_kill`, wait for the job to finish stopping, and retry. The registry does not queue, preempt, or maintain a second mutable counter.

-## Lifecycle
+-----
 
-Jobs belong to their owner and backend, not the producer tool fiber, so producer and controller reloads do not stop them. The first job for an owner attaches one awaited effect to the exact `Agent` scope. Owner disposal cancels that object's jobs, awaits producer quiescence, and removes their snapshots; reused agent or session ids cannot redirect an old cleanup.
+<a id="use-this-package"></a>
+## Use this package
 
-Service disposal closes listeners, cancels all live jobs, awaits their records, and detaches effects from surviving owner scopes. If teardown cancellation throws, the service force-fails the record and warns that work may be orphaned instead of deadlocking. A cancellation that returns but never settles `done` remains indistinguishable from a slow stop and can stall teardown.
+Load this plugin when a composition needs in-process background jobs: long-running tools register their work, and the owning agent reads, waits on, lists, and cancels it without blocking its own turn. It implements the [`dsh-jobs`](../jobs/README.md) contract; the model-facing `job_output`, `job_list`, and `job_kill` tools come from [`dsh-tool-jobs`](../tool-jobs/README.md).
 
-Settlement is first-wins: the earliest terminal outcome — producer settlement, a rejected `done` contained as `failed`, or a teardown force-failure — records once, releases waiters, and notifies listeners once with per-listener containment. Pending waits mark the job reported before listeners run so completion reporters do not duplicate notices, and a teardown cancel marks it for the same reason: nothing will read a notice addressed to an owner being destroyed. Completion is the last thing a settlement announces, after the record is committed and the visible-set change is published, because a reporter may open a model turn synchronously and every other observer must already have seen the settled record.
+### When to choose it
 
-Controllers and listeners are layered by the scope that registered them, in the tools-registry shape: a registration files into its registering context's scope, and a read unions the global layer with the owner's scope chain. One process-wide registry therefore answers per-owner questions per owner — `start()` refuses `background jobs unavailable: no job controller serves this agent (load @deepseek-ai/dsh-tool-jobs in its composition)` for an owner whose own composition attaches none, however many other compositions attach theirs, and a settlement reaches only the listeners its owner's composition registered.
+Choose it when jobs should live in the harness process and die with it. Avoid it when work must survive a restart or span processes: records are in-memory, so a durable or cross-process backend must implement the same contract differently.
 
+### Minimal configuration
+
+Loading the plugin registers `ctx.jobs`; `maxConcurrentJobsPerOwner` is optional and defaults to `10`.
+
+```yaml
+- name: '@deepseek-ai/dsh-jobs-local'
+```
+
+| Field | Default | Meaning |
+|---|---|---|
+| `maxConcurrentJobsPerOwner` | `10` | Maximum `running` plus `stopping` jobs per exact owner, or in the shared unowned bucket |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-jobs-local) is the exhaustive source for the accepted field.
+
+### What each owner gets
+
+The limit counts the exact owner's `running` and `stopping` records; all unowned jobs share one separate service-level bucket. Terminal history does not occupy capacity, and only a producer's `done` settlement releases a stopping job's place. At capacity, `start()` fails before the producer runs, with an error that names the limit and tells the agent to kill an unneeded job, wait for it to finish, and retry — the registry neither queues nor preempts.
+
+### Lifecycle
+
+Jobs belong to their owner and backend, not to the producer tool, so producer or controller reloads do not stop them. When an agent that owns jobs is disposed, its jobs are cancelled, their producers awaited, and their snapshots removed; service disposal does the same for every remaining job. A cancellation that throws during teardown force-fails the record and warns that the work may be orphaned, so teardown never deadlocks.
+
+### What can go wrong
+
+Starting work fails without a controller that serves the owner — loading `dsh-tool-jobs` attaches one, and `start()` otherwise refuses with a message naming it. A producer cancel that returns without settling `done` stays indistinguishable from a slow stop and can stall teardown while holding one capacity slot. Every record disappears when the harness process exits.

+## Understand the implementation

+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the registry and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+- **In-memory records, fresh snapshots.** `LocalJobRegistry` keeps one `TrackedTask` per job and projects a new read-only snapshot per call; callers never receive live state.
+- **Owner-relative layers, one process-wide registry.** Controllers, completion listeners, and change observers are filed into the scope that registered them (`ScopedLayers`), and reads union the global layer with the owner's scope chain — so one preset's job controls never hold `start()` open for an agent whose own composition loads none, and a settlement reaches only the listeners its owner's composition registered.
+- **Preflight before start.** `start()` checks controller service, spec validity, live ownership, and capacity before invoking the producer, so a rejection leaves no job id or execution resource; registration commits without a later failable step.
+- **First-wins settlement, completion last.** The earliest terminal outcome records once, releases waiters, and notifies listeners once with per-listener containment; completion is announced after the record is committed and the visible-set change published, because a reporter may open a model turn synchronously.
+- **Teardown never deadlocks.** A throwing cancel force-fails the record and reports a possible orphan instead of stalling disposal.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `Config` schema, `LocalJobRegistry`, admission, lifecycle, teardown |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; snapshot checks live in `dsh-jobs/invariant`) |
+
+### Scope layers
+
+`attachController`, `onJobDone`, and `onJobsChanged` register into the calling context's scope layer. The controller question (`servesOwner`) and listener delivery (`listenersFor`, `changedFor`) walk the same chain: global layer first, then each scoped layer along the owner's chain. Registrations are anonymous tokens so duplicate labels stay independently disposable.

+`activeTaskCount` counts authoritative records per exact owner or in the shared unowned bucket. `settle` marks a job reported when waiters are pending, resolves every waiter, records the terminal snapshot, announces the visible-set change, then notifies completion listeners. Pending waits mark the job reported before listeners run so completion reporters do not duplicate notices; a teardown cancel marks it for the same reason — nothing will read a notice addressed to an owner being destroyed.
+
+### Teardown
+
+Owner disposal (`disposeOwned`) cancels the owner's jobs, awaits their settlement, removes their records, and announces the removal — the one visible-set change no per-job record carries. Service disposal (`disposeAll`) closes listeners, cancels all live jobs, awaits settlement, clears the store, announces the emptying to the distinct owners, then detaches the cross-fiber owner-cleanup effects.

 ## Known Limitations and Deferred Work
 
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define when the registry is a poor fit. They are current package constraints, not a task backlog.
+
 - **Jobs are process-local** — records die with the harness process; durable or cross-restart execution needs a separate backend implementing the seam.
 - **A silently ineffective cancel can stall teardown and hold capacity** — if `cancel` returns without settling `done`, the registry cannot distinguish it from a slow stop; the job keeps one bucket slot for the rest of the service lifetime, and only an explicit throw can be force-failed safely.

 # @deepseek-ai/dsh-jobs-local
 
 [English](README.md) | 中文
 
-[`@deepseek-ai/dsh-jobs`](../jobs/README.zh.md) 注册表约定的进程本地实现：`LocalJobRegistry` 把每条记录保存在内存中，按 kind 签发 `<kind>-N` id，并且只交出全新快照，从不交出实时状态。作为插件加载后即注册为 `ctx.jobs`。
+## 概述
 
-## 准入
+`dsh-jobs-local` 在 harness 进程内运行后台任务：工作会在 agent 继续推进的同时保持运行，拥有它的 agent 可以读取、等待、列出和取消它；同时挂载 `dsh-tool-jobs` 时，完成以会话内通知送达。它用内存记录实现 `dsh-jobs` 约定，并且只交出全新快照，从不交出实时状态。按所有者的并发上限（默认 10）约束一个 agent 同时处于运行或停止中的任务数量；任务会随 harness 进程终止而消失，无法跨重启持久。
 
-`maxConcurrentJobsPerOwner` 必须是正的安全整数，默认值为 `10`。调用生产方之前，`start()` 会统计确切 owner 的 `running` 与 `stopping` 记录；所有无 owner 任务共享另一个独立的服务级桶。终止历史不占用容量，处于 `stopping` 的任务只有在生产方 `done` 结算后才释放名额。
+## 目录
 
-达到容量时，`start()` 会在生产方执行和 id 分配前失败；错误会给出上限，并告诉模型使用 `job_kill`、等待任务完全停稳后再重试。注册表不会排队或抢占任务，也不会维护第二份可变计数。

-## 生命周期
+-----
 
-任务属于其所有者和后端，而不是生产方工具 fiber，因此重载生产方或控制器不会停止任务。某个所有者的第一个任务会把一个会被等待的 effect 附加到对应 `Agent` 对象的 scope 上。所有者的 dispose（资源释放）会取消该对象的任务，等待生产方完全停稳，并移除其快照；复用的 agent（智能体）id 或会话 id 无法重定向旧的清理操作。
+<a id="use-this-package"></a>
+## 使用本包
 
-服务 dispose 会关闭监听器、取消所有存活任务、等待其记录完成，并从仍存活的所有者 scope 中分离 effect。如果销毁期间的取消操作抛出异常，服务会强制将记录标为失败，并警告工作可能成为孤立工作，而不会死锁。取消操作已返回但 `done` 始终未结算时，系统无法将其与缓慢停止区分开，销毁过程可能因此停滞。
+当组合需要进程内后台任务时加载本插件：长时间运行的工具注册其工作，拥有它的 agent 在不阻塞自身轮次的情况下读取、等待、列出和取消。它实现 [`dsh-jobs`](../jobs/README.zh.md) 约定；模型侧的 `job_output`、`job_list` 与 `job_kill` 工具来自 [`dsh-tool-jobs`](../tool-jobs/README.zh.md)。
 
-结算遵循首次结算优先原则：最早出现的终止结果（生产方结算、作为 `failed` 隔离处理的 `done` 拒绝，或销毁时的强制失败）只记录一次，随后释放等待方，再只通知监听器一次；各监听器的故障会单独隔离。挂起的等待会在监听器运行前把任务标记为已报告，因此完成报告方不会重复发出通知；销毁时的取消出于同样的理由也会标记：面向正在被销毁的所有者的通知不会有人读到。完成是一次结算最后才宣布的事情，排在记录提交与可见集变更发布之后，因为报告方可能同步开启一个模型轮次，而该结算的其他所有观察者都必须已经看到已结算的记录。
+### 何时选择
 
-控制器与监听器按注册方所在的 scope 分层，形状与 tools 注册表一致：一次注册归档到其注册上下文的 scope，一次读取则把全局层与所有者的 scope 链求并集。因此一个进程级注册表能逐所有者地回答逐所有者的问题——对自身组合未附加任何控制器的所有者，无论其他组合附加了多少，`start()` 都会拒绝并抛出 `background jobs unavailable: no job controller serves this agent (load @deepseek-ai/dsh-tool-jobs in its composition)`；一次结算也只会抵达其所有者所属组合注册的监听器。
+当任务应存活于 harness 进程内、并随进程终止时选择它。当工作必须跨重启存活或跨进程存在时避免它：记录保存在内存中，持久或跨进程后端必须以不同方式实现同一约定。
 
+### 最小配置
+
+加载插件即注册 `ctx.jobs`；`maxConcurrentJobsPerOwner` 可选，默认为 `10`。
+
+```yaml
+- name: '@deepseek-ai/dsh-jobs-local'
+```
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `maxConcurrentJobsPerOwner` | `10` | 每个精确所有者，或共享的无主桶中，`running` 加 `stopping` 任务的最大数量 |
+
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-jobs-local)是每个受支持字段的穷尽式真源。
+
+### 每个所有者得到什么
+
+上限统计精确所有者的 `running` 与 `stopping` 记录；所有无主任务共享另一个独立的服务级桶。终止历史不占用容量，只有生产方的 `done` 结算才释放一个停止中任务的名额。达到上限时，`start()` 会在生产方运行前失败，错误会指出上限并告诉 agent 终止一个不需要的任务、等它结束后再重试——注册表既不排队也不抢占。
+
+### 生命周期
+
+任务属于其所有者和后端，而非生产方工具，因此重载生产方或控制器不会停止任务。拥有任务的 agent 被释放时，其任务会被取消、生产方会被等待、快照会被移除；服务释放对每个剩余任务执行同样的操作。销毁期间抛出的取消会强制失败记录并警告工作可能成为孤立工作，因此销毁永远不会死锁。
+
+### 可能出什么问题
+
+没有服务于所有者的控制器时无法启动工作——加载 `dsh-tool-jobs` 即附加一个，否则 `start()` 会以指出它的消息拒绝。返回但始终未结算 `done` 的生产方取消与缓慢停止无法区分，可能使销毁停滞并持续占用一个容量名额。每条记录都会在 harness 进程退出时消失。

+
+本节解释注册表背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+- **内存记录，全新快照。** `LocalJobRegistry` 为每个任务保存一条 `TrackedTask`，每次调用都投影出新的只读快照；调用方永远不会拿到实时状态。
+- **按所有者分层，一个进程级注册表。** 控制器、完成监听器与变更观察者归档到注册方所在的 scope（`ScopedLayers`），读取把全局层与所有者的 scope 链求并集——因此某个 preset 的任务控制绝不会为自身组合未加载任何控制器的 agent 保持 `start()` 可用，一次结算也只会抵达其所有者所属组合注册的监听器。
+- **启动前先预检。** `start()` 在调用生产方之前检查控制器服务、spec 有效性、仍存活的所有权与容量，因此拒绝不会留下 job id 或执行资源；注册一旦提交，后续不再有可失败步骤。
+- **结算首次优先，完成最后。** 最早的终止结果只记录一次，释放等待方，并只通知监听器一次，各监听器故障单独隔离；完成在记录提交且可见集变更发布之后才宣布，因为报告方可能同步开启一个模型轮次。
+- **销毁永不死锁。** 抛出的取消会强制失败记录并报告可能的孤立工作，而不是让释放停滞。

 # @deepseek-ai/dsh-jobs
 
 English | [中文](README.zh.md)
 
-The background job registry contract (`ctx.jobs`). The abstract `JobRegistry` and its vocabulary types give long-running producers shared ids, owner isolation, reads, cancellation, waiting, notices, and cleanup under one contract; the process-local registry lives in [`dsh-jobs-local`](../jobs-local/README.md). Producer plugins extend `JobKindMap` with their opaque id namespace.
+## Summary
 
-## Service contract
+`dsh-jobs` lets tools run long work as background jobs: the work gets a stable `<kind>-N` id, keeps running while the agent moves on, and the owning agent can read its output, wait for it with a timeout, or request cancellation at any time. Jobs belong to the agent session that started them, so one agent's work is never visible to another, and completion reaches the owner as an in-session notice rather than by polling. This package ships the contract only: the process-local registry lives in `dsh-jobs-local`, and the model-facing controls and completion notices live in `dsh-tool-jobs`. Load an implementation to get background jobs; without one, `ctx.jobs` does not exist and `start()` cannot run.
 
-- `start(spec): JobId` validates the attached controller, spec, exact live owner, optional positive `outputLimitBytes`, and any provider-owned admission policy before calling the producer's `run()` once. A preflight rejection or starter throw leaves no job id or registered work; successful return commits without another failable step.
-- `get(id, caller?)` and `list(caller?)` return non-consuming snapshots. Listing includes only caller-owned and unowned jobs.
-- `read(id, caller?)` consumes the single cursor for stream jobs and reads terminal output idempotently for final-output jobs.
-- `kill(id, caller?, reason?)` invokes producer cancellation before changing status. A cancellation throw leaves the job running; success changes it to `stopping` and marks terminal delivery reported.
-- `wait(id, timeoutMs, caller?, signal?)` returns a terminal snapshot or the live snapshot at timeout. Aborting stops only the wait; settlement wins once it has committed terminal delivery to that waiter.
-- `onJobDone(listener)` observes each terminal record with the exact owner. Listener throws and rejections are contained; listener work is not awaited.
-- `onJobsChanged(listener)` observes visible-set changes — registration, every stopping transition (teardown's included, before it awaits a slow producer), settlement, owner-disposal removal, and the emptying service disposal commits — carrying only the owner whose set moved, or `undefined` when an unowned job changed and every caller's set moved with it. It is owner-granular because removal is a change no per-job record can express, and it is not a superset of `onJobDone`: it carries no delivery meaning and marks nothing reported. The registration binds to the calling fiber, so an observer mounted outside the registry still sees the disposal emptying.
-- `attachController(name)` declares a job controller for its effect lifetime. `start()` fails before producer execution when no attached controller serves the spec's owner.
+## Table of Contents
 
-All three registrations are owner-relative, because one registry serves every composition in the process. A controller or listener registered from an unscoped context serves every owner; one registered under an agent composition's scope serves exactly the agents composed under it. So a composition that loads no controller cannot start background work on the strength of another composition's controls, and one settlement notifies only the listeners its owner's composition registered.

+- [Further Exploration](#further-exploration)

+- [Known Limitations and Deferred Work](#known-limitations-and-deferred-work)
+- [Dev Note](#dev-note)
 
-Owned access compares the job's `SessionId` with the caller's. Ids such as `bash-1` are predictable, so this fence is the boundary. Unowned jobs are open to callers and last until service disposal.
+-----
 
-`outputLimitBytes` is producer-owned model-presentation policy carried unchanged into snapshots. A controller applies it after adding status or notice metadata; the registry does not rewrite producer output or invent a default for producers that omit it.
+<a id="use-this-package"></a>
+## Use this package
 
-Implementations also owe the lifecycle semantics of the contract: registrations outlive producer and controller fibers, owner and service disposal cancel live work and await compliant producers, and settlement is first-wins — one terminal record, one round of contained listener notification, released waiters.
+Use this package when you are composing a background-job capability or writing a producer that registers long work. The package itself defines the contract; a composition gets the feature by loading an implementation such as `dsh-jobs-local` and, for the model side, `dsh-tool-jobs`.
 
-See the [job type catalog](../../../docs/subsystems/jobs.md), the [runtime Agent Note](../../../.agents/notes/implemented/architecture/2026-06-20-generic-long-running-tool-runtime.md), and the [seam Agent Note](../../../.agents/notes/implemented/architecture/2026-07-26-job-registry-seam.md).
+### What a background job gives you
 
+A producer registers work with a kind and a one-line label; the registry returns a `<kind>-N` id such as `bash-1`. Anyone who owns the job can read output, list jobs, wait up to a timeout for settlement, and request cancellation — each call returns a fresh snapshot of the job's status, from `running` and `stopping` to the terminal `completed`, `killed`, or `failed`. When a job settles, the owning agent is notified through the completion listener that `dsh-tool-jobs` turns into an in-session notice, so no polling is needed. A producer may attach an optional byte cap so each complete model-facing output read or completion notice stays bounded.
+
+### The ownership boundary
+
+A job belongs to the agent session that started it: another agent cannot read or stop it. Ids such as `bash-1` are predictable, so this fence is authorization, not secrecy. A job started without an owner is open to any caller and lasts until the service is disposed.
+
+### Starting background work needs a controller
+
+A producer can start work only while a controller that serves the owner is attached — loading `dsh-tool-jobs` attaches one. An agent whose composition loads no controller cannot start background work; `start()` fails with a message that names the missing controller rather than starting work the agent could never collect or stop.
+
+### Smallest working composition
+
+```yaml
+- name: '@deepseek-ai/dsh-jobs-local'
+- name: '@deepseek-ai/dsh-tool-jobs'
+```
+
+Loading these two plugins on a harness base that already provides the agent, tools, and system-prompt services gives the full feature: `dsh-jobs-local` provides the in-process background-job registry, and `dsh-tool-jobs` provides the `job_output`, `job_list`, and `job_kill` tools plus completion-notice delivery.
+
+### What can go wrong
+
+Any preflight rejection leaves no job id or registered work. Jobs managed by the shipped in-process registry die with the harness process; durable execution across restarts needs a different backend implementing this contract.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the contract and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+- **Contract and implementation are separate packages.** `JobRegistry` is an abstract Cordis service; loading the class directly throws, so a misconfigured composition fails at load instead of registering an empty `ctx.jobs`.
+- **One registry per process, owner-relative answers.** One instance serves every composition in the process, so registrations and deliveries are relative to the registering scope: a controller or listener registered from an unscoped context serves every owner; one registered under an agent composition's scope serves exactly the agents composed under it.
+- **Access is fenced by the owner's session id.** Ids are predictable, so authorization — not secrecy — is the boundary.
+- **Settlement is first-wins, and completion is announced last.** One terminal record, released waiters, and one round of contained listener notification; completion is announced after the record is committed and every other observer has seen it, because a reporter may open a model turn synchronously.
+- **Registrations outlive producer and controller fibers.** Owner and service disposal cancel live work and await compliant producers; a throwing teardown cancel force-fails only the record.

+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion: validates snapshot identity, status, timestamps, and owner fields |
+
+### Service operations
+
+Every operation is a thin projection over the registered jobs: `get` and `list` return non-consuming snapshots, `read` advances the single stream cursor, `kill` invokes producer cancellation before changing status, `wait` blocks up to a timeout, and `start()` preflights access, validation, and admission before invoking the producer's `run()` once while refusing any owner no attached controller serves; listeners observe terminal records and visible-set changes at owner granularity, and `attachController` scopes controller availability to its effect lifetime. Exact signatures and behavior live in the JSDoc on [`src/index.ts`](src/index.ts) and the generated [`ctx.jobs` cordis surface](../../../docs/subsystems/jobs.md).

+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define when the contract is a poor fit. They are current package constraints, not a task backlog.
+
+- **The contract is in-process** — `JobStart.run()` passes callbacks and exact `Agent` objects; a durable or cross-process backend must reshape identity, restart, ownership, and observation semantics before it can implement this seam.
 - **Stream output has one consuming cursor** — independent observers need a cursor or snapshot API.
 - **Foreground work cannot be promoted** — producers choose foreground or background before starting.

 [English](README.md) | 中文
 
-后台任务注册表约定（`ctx.jobs`）。抽象的 `JobRegistry` 及其词汇类型在同一份约定下为长时间运行的生产方提供共享 id、owner 隔离、读取、取消、等待、通知和清理；进程局部注册表位于 [`dsh-jobs-local`](../jobs-local/README.zh.md)。生产方插件使用其不透明 id namespace 扩展 `JobKindMap`。
+## 概述
 
-## 服务约定
+`dsh-jobs` 让工具可以把长时间工作注册为后台任务：工作获得稳定的 `<kind>-N` id，在 agent 继续推进的同时保持运行，拥有它的 agent 可以随时读取输出、带超时等待或请求取消。任务属于启动它的 agent 会话，因此一个 agent 的工作永远不会被另一个 agent 看到；完成以会话内通知而非轮询的方式送达给拥有者。本包只提供约定：进程本地注册表位于 `dsh-jobs-local`，模型侧控制与完成通知位于 `dsh-tool-jobs`。加载一个实现才能获得后台任务；没有实现时 `ctx.jobs` 不存在，`start()` 无法运行。
 
-- `start(spec): JobId` 验证已附加的任务控制器、spec、确切且仍存活的 owner、可选的正数 `outputLimitBytes`，以及 Service Provider 所拥有的准入策略，然后只调用生产方的 `run()` 一次。预检拒绝或启动方抛出异常时都不会生成 job id 或注册工作；成功返回会直接提交，不再执行其他可能失败的步骤。
-- `get(id, caller?)` 和 `list(caller?)` 返回非消费式快照。列表只包含调用方拥有及无 owner 的任务。
-- `read(id, caller?)` 消费流任务的唯一游标；对于最终输出任务，则以幂等方式读取终止输出。
-- `kill(id, caller?, reason?)` 在更改状态前调用生产方取消。取消抛出异常时任务保持运行；成功则把状态改为 `stopping`，并将终止交付标记为已报告。
-- `wait(id, timeoutMs, caller?, signal?)` 返回终止快照，或在超时时返回存活快照。中止只会停止等待；一旦终止交付已向该等待方提交，终止结果优先。
-- `onJobDone(listener)` 观察每条终止记录及其精确 owner。监听器抛出的异常和产生的拒绝都会被隔离；系统不会等待监听器工作。
-- `onJobsChanged(listener)` 观察可见集合的变化——注册、每一次转入 stopping（包括 teardown 在等待缓慢生产者之前的那一次）、结算、owner 销毁时的移除，以及服务销毁提交的清空——只携带集合发生变化的那个 owner，或在无主任务变化、因而每个调用方的集合都随之变化时携带 `undefined`。它按 owner 分粒度，因为移除是任何逐任务记录都无法表达的变化；它也不是 `onJobDone` 的超集：它不含任何投递含义，也不把任何东西标为已上报。注册绑定的是调用方 fiber，因此挂在注册表之外的观察者仍能收到销毁时的清空。
-- `attachController(name)` 在其 effect 生命周期内声明任务控制器。当没有任何已附加的控制器服务于 spec 的所有者时，`start()` 会在生产方执行前失败。
+## 目录
 
-这三类注册都是相对于所有者的，因为一个注册表要服务进程内的每一套组合。从不带 scope 的上下文注册的控制器或监听器服务于每个所有者；在某套 agent 组合的 scope 下注册的，则恰好服务于在该组合下组合出的 agent。因此，未加载任何控制器的组合无法借另一套组合的控制工具启动后台工作，而一次结算也只会通知其所有者所属组合注册的监听器。

-有 owner 的访问会比较任务的 `SessionId` 与调用方。`bash-1` 等 id 可预测，因此这道隔离是安全边界。无 owner 的任务向调用方开放，并持续到服务 dispose（资源释放）为止。
+-----
 
-`outputLimitBytes` 是生产方拥有的模型呈现策略，会原样携带到快照中。控制器在添加状态或通知元数据后应用它；注册表不会重写生产方输出，也不会为省略此字段的生产方虚构默认值。
+<a id="use-this-package"></a>
+## 使用本包
 
-实现还必须兑现约定的生命周期语义：注册的存续期长于生产方 fiber 与控制器 fiber，owner 释放和服务释放会取消仍在运行的工作并等待守约的生产方，结算遵循首次结果优先（一条终止记录、一轮异常受到隔离的监听器通知，然后释放等待方）。
+在组合后台任务能力或编写注册长时间工作的生产方时使用本包。本包本身定义约定；组合通过加载 `dsh-jobs-local` 这样的实现，以及模型侧的 `dsh-tool-jobs`，获得该功能。
 
-参见[任务类型目录](../../../docs/subsystems/jobs.zh.md)、[运行时 Agent Note](../../../.agents/notes/implemented/architecture/2026-06-20-generic-long-running-tool-runtime.zh.md)和 [seam Agent Note](../../../.agents/notes/implemented/architecture/2026-07-26-job-registry-seam.zh.md)。
+### 后台任务提供什么
 
+生产方以 kind 和一行标签注册工作；注册表返回 `<kind>-N` id，例如 `bash-1`。拥有任务的任何一方都可以读取输出、列出任务、带超时等待结算或请求取消——每次调用都返回任务状态的全新快照，从 `running`、`stopping` 到终止态的 `completed`、`killed` 或 `failed`。任务结算时，拥有它的 agent 会通过 `dsh-tool-jobs` 转成会话内通知的完成监听器得到通知，因此无需轮询。生产方还可以附加可选的字节上限，让每次完整的模型侧输出读取或完成通知保持有界。
+
+### 归属边界
+
+任务属于启动它的 agent 会话：其他 agent 无法读取或停止它。`bash-1` 这样的 id 可预测，因此这道隔离是授权，而非保密。没有所有者启动的任务对任何调用方开放，并持续到服务被释放为止。
+
+### 启动后台工作需要一个控制器
+
+只有附加了服务于所有者的控制器时，生产方才能启动工作——加载 `dsh-tool-jobs` 即附加一个。组合中未加载任何控制器的 agent 无法启动后台工作；`start()` 会以指出缺失控制器的消息失败，而不会启动 agent 永远无法收集或停止的工作。
+
+### 最小可用组合
+
+```yaml
+- name: '@deepseek-ai/dsh-jobs-local'
+- name: '@deepseek-ai/dsh-tool-jobs'
+```
+
+在已提供 agent、tools 与 system-prompt 服务的 harness 基础上加载这两个插件，即可获得完整功能：`dsh-jobs-local` 提供进程内后台任务注册表，`dsh-tool-jobs` 提供 `job_output`、`job_list`、`job_kill` 工具以及完成通知投递。
+
+### 可能出什么问题
+
+任何预检拒绝都不会留下 job id 或已注册的工作。由随附的进程内注册表管理的任务会随 harness 进程终止而消失；跨重启的持久执行需要一个实现本约定的不同后端。

+
+### 设计理念
+
+- **约定与实现分属不同包。** `JobRegistry` 是抽象 Cordis 服务；直接加载该类会抛出异常，因此错误配置的组合会在加载时失败，而不是注册一个空的 `ctx.jobs`。
+- **每进程一个注册表，按所有者给出答案。** 一个实例服务进程内的每套组合，因此注册与投递都相对注册方所在 scope：从不带 scope 的上下文注册的控制器或监听器服务于每个所有者；在某套 agent 组合的 scope 下注册的，恰好服务于该组合下组合出的 agent。
+- **访问以所有者的会话 id 为界。** id 可预测，因此是授权——而非保密——构成边界。
+- **结算首次优先，完成最后宣布。** 一条终止记录、释放的等待方，以及一轮受到隔离的监听器通知；完成在记录提交且该结算的所有其他观察者都已看到之后才宣布，因为报告方可能同步开启一个模型轮次。
+- **注册的存续期长于生产方与控制器 fiber。** 所有者与服务释放会取消正在运行的工作并等待守约的生产方；抛出异常的销毁取消只强制失败记录。

-The model-facing controller for `ctx.jobs`: three kind-independent tools, completion notices, and one background-work prompt section. Loading the plugin attaches the controller required by `ctx.jobs.start()`.
+## Summary
 
-## Tools
+`dsh-tool-jobs` gives the agent three kind-independent tools for background work — `job_output`, `job_list`, and `job_kill` — so any job the agent started, whether a background command, a PTY send, or a subagent, is read, listed, and cancelled through the same controls. When a job finishes, the owning agent is told in-session: a busy agent gets the notice in its next step, an idle agent is woken with a follow-up turn, bounded per owner. Loading the plugin also attaches the job controller that lets producers start background work. The tools are generic UI cards over `ctx.jobs`; configuration tunes wait timeouts and completion delivery.
 
-- `job_output(job_id, wait?, timeout_ms?)` reads without blocking by default. Stream jobs return only the next delta; final-output jobs return their result after settlement. Every response ends with `[status: ...]`. `wait: true` waits up to the configured cap and leaves a still-running job alive on timeout.
-- `job_list()` returns caller-visible jobs as `<id> [<kind>] <status> — <label>`.
-- `job_kill(job_id, reason?)` requests cancellation immediately and forwards the logged reason. Terminal jobs return a non-consuming snapshot.
+## Table of Contents
 
-All three use generic UI cards: `read` for output and list, `execute` for kill.

-Their canonical values are `{ text, job }`, `PublicJobSnapshot[]`, and `{ outcome: 'cancellation-requested' | 'already-finished', job }`. A public snapshot carries id, kind, label, status/detail, and start/finish times; it deliberately omits `ownerSession` and the internal `reported` notice bit. Native renderers preserve the status and acknowledgement text above.
+-----
 
-When a producer supplies `outputLimitBytes`, `job_output`, terminal `job_kill`, and completion notices cap the complete Native UTF-8 result after adding status or notice text. Reads retain the output tail and control suffix when they fit; a bounded completion notice instead reserves `background job <id>` and the `job_output` collection instruction before spending remaining bytes on its variable kind, label, status, detail, and truncation marker. A prepended pre-execute listener captures the caller-visible job before policy, and each job-control definition's final-content callback applies its producer cap to single-text denials, short-circuits, normalized tool or pipeline failures, replacements, and blocks; structured multi-block policy results retain their shape. An existing producer truncation marker is reused rather than duplicated. Producers that omit the field retain the existing unbounded controller behavior.
+<a id="use-this-package"></a>
+## Use this package
 
-## Completion notices
+Load this plugin in any composition where the agent should start, observe, and stop background jobs: it registers the three tools, attaches the controller producers need, and delivers completion notices. It requires the `ctx.tools`, `ctx.jobs`, and `ctx.systemPrompt` services from the composed harness.
 
-An unreported completion delivers `background job <id> (<kind>: <label>) finished [status: ...]. Read its output with job_output.` to the exact owner. When bounded, the stable id prefix and collection command outrank variable label/detail so the notice remains actionable at PTY's supported 64-byte minimum. A kill or terminal read/wait marks delivery reported and suppresses the redundant notice, as does the teardown cancel that drains an owner or the service.
+### The three tools
 
-Which lane carries it depends on what the owner is doing. A busy owner is injected: the notice joins the next-step inbox, and the turn cannot close while that inbox holds it, so several jobs settling together cost one step rather than one turn each. An idle owner is instead woken with a follow-up turn, because a pending notice nothing claims is a completion the model never learns about. `completionDelivery: quiet` keeps the injection lane for idle owners too, which is what a deterministic transcript needs.
+- `job_output(job_id, wait?, timeout_ms?)` — Read a job's output. Stream jobs return only the output since the previous read; final-output jobs return their result after settlement. Every response ends with `[status: ...]`. Reads are non-blocking unless `wait: true`, which waits up to the configured cap and leaves a still-running job alive on timeout.
+- `job_list()` — List your background jobs with their ids, kinds, and statuses, one per line: `<id> [<kind>] <status> — <label>`.
+- `job_kill(job_id, reason?)` — Request cancellation of a running job immediately; the job settles as `killed` once its work actually stops. A terminal job returns its current snapshot, and the optional reason is recorded and forwarded to the job.
 
-Waking is bounded. Each owner may open `maxConsecutiveWakes` turns this way before further notices degrade to injection, and claiming any user-authored message restores the budget. The bound exists because the chain is self-exciting: a woken turn may start the background job whose completion wakes it again. Notices this plugin queued never refill the budget they spent.
+The three tools return `{ text, job }`, `PublicJobSnapshot[]`, and `{ outcome: 'cancellation-requested' | 'already-finished', job }` respectively. A public snapshot carries id, kind, label, status/detail, and start/finish times and omits ownership and notification bookkeeping. All three render through generic UI cards: `read` for output and list, `execute` for kill.
 
-One host registry may carry several mounts of this plugin — one per agent preset. The registry routes each settlement to the listeners the owner's scope chain reaches, so a mount under one preset never sees another preset's agents and an agent reads exactly one notice per completion however many presets are mounted. The same routing decides which agents this mount's controller serves: an agent whose composition loads no `tool-jobs` cannot start background work at all.
+### Completion notices
 
-## Config
+When a job finishes, the owning agent receives `background job <id> (<kind>: <label>) finished [status: ...]. Read its output with job_output.` as an in-session message. A busy agent has the notice injected into its next step — the turn cannot close while the inbox holds it, so several jobs settling together cost one step rather than one turn each. An idle agent is instead woken with a follow-up turn, because an unclaimed notice is a completion the model never learns about. A kill or a terminal read/wait marks the completion reported and suppresses the redundant notice, as does the teardown cancel that drains an owner or the service.
 
-| key | default | meaning |
+Waking is bounded: each owner may be woken `maxConsecutiveWakes` times before further notices degrade to injection, and claiming any user-authored message restores the budget. The bound exists because the chain is self-exciting — a woken turn may start the background job whose completion wakes it again. `completionDelivery: quiet` keeps even idle owners on the injection lane, which deterministic transcripts need.
+
+### Minimal configuration
+
+Loading the plugin with no config is the common path; a `waitTimeoutMs` above `maxWaitTimeoutMs` fails at load.
+
+```yaml
+- name: '@deepseek-ai/dsh-tool-jobs'
+```
+
+| Field | Default | Meaning |
 |---|---|---|
-| `waitTimeoutMs` | `30000` | wait used when `wait: true` omits `timeout_ms` |
-| `maxWaitTimeoutMs` | `600000` | cap for model-supplied waits |
+| `waitTimeoutMs` | `30,000` | Wait used when `wait: true` omits `timeout_ms` |
+| `maxWaitTimeoutMs` | `600,000` | Cap for model-supplied waits; larger values clamp down to it |
 | `completionDelivery` | `wakeup` | `wakeup` opens a turn on an idle owner; `quiet` leaves the notice pending |
-| `maxConsecutiveWakes` | `3` | turns one owner may open by wake before notices degrade to injection |
+| `maxConsecutiveWakes` | `3` | Turns one owner may open by wake before notices degrade to injection |
 
-A default above the cap fails at load.
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-tool-jobs) is the exhaustive source for every accepted field and its JSDoc.
 
+### What can go wrong
+
+An agent whose composition loads no `tool-jobs` cannot start background work: this plugin's controller is what arms producers' `ctx.jobs.start()`. A model-supplied wait longer than `maxWaitTimeoutMs` is clamped down to the cap, and a timed-out wait returns `[status: running]` and leaves the job alive rather than failing. A completion notice pending on an idle owner does not survive that owner's disposal.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the tools and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+- **Kind-independent controls.** The same three tools read, list, and cancel jobs of every producer kind — bash, subagent, PTY — because all of them register through the generic `ctx.jobs` runtime.
+- **Delivery is owned here; recipients are the registry's.** The plugin decides how an unreported completion reaches the owner — injected into a busy step, or a woken turn on an idle owner — while the registry routes each settlement to the listeners its owner's scope chain reaches, so a mount under one preset never sees another preset's agents, and an agent reads exactly one notice per completion however many presets are mounted.
+- **Producer-owned output bounds.** When a producer supplies `outputLimitBytes`, the complete model-facing result — output read, terminal kill snapshot, or completion notice — is capped after status and notice metadata are added; producers that omit it keep unbounded behavior.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: tool registrations, completion listener, prompt section, output capping |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; execution relations are owned by the capability seam) |
+
+### Output capping
+
+`job_output` and `job_kill` capture the caller-visible job in a prepended pre-execute listener before policy runs, so the producer's cap applies to the complete rendered result. `job_output` preserves its output/status split when policy left the default rendering intact, bounding the output tail and the `[status: ...]` suffix; other single-text results — denials, short-circuits, normalized tool or pipeline failures, replacements, and blocks — are bounded as one text, while structured multi-block policy results keep their shape. A bounded completion notice reserves the stable `background job <id>` prefix and the `job_output` collection instruction before spending remaining bytes on variable kind, label, status, detail, and truncation marker, so the notice stays actionable at the PTY's supported 64-byte minimum; an existing producer truncation marker is reused rather than duplicated.
+
+### Notice delivery lanes
+
+`onJobDone` skips jobs already reported or unowned. A `wakeup` delivery opens a turn on an idle owner while the budget lasts, tracked per exact `Agent` in a `WeakMap`; claiming a user-authored message (`agent/inbox/claimed`) resets that owner's budget. A busy owner — or any notice past the budget, or `quiet` delivery — is injected into the next-step inbox instead. Teardown settlements arrive already `reported`, so disposal never spends a model request announcing a notice nobody can read.

 - **A settlement inside the driver's retirement window still strands its notice** — between the turn loop's last inbox check and the driver committing its idle phase the owner still reads as busy, so the notice is injected and nothing wakes. Steering has the same hole; closing it belongs to `agent-loop`.
 - **A spent wake budget is not restored by time** — only user-authored input refills it, so an unattended agent whose budget ran out collects its remaining notices on the next turn something else opens.
 - **A notice pending on an idle owner does not survive that owner's disposal** — the disposal cancel clears the unclaimed inbox, and the log keeps the insert/cancel pair as the record.

-`ctx.jobs` 的面向模型控制器：三个与 kind 无关的工具、完成通知和一个后台工作提示词区段。加载该插件会附加 `ctx.jobs.start()` 所要求的控制器。
+## 概述
 
-## 工具
+`dsh-tool-jobs` 为 agent 提供三个与 kind 无关的后台工作工具——`job_output`、`job_list` 与 `job_kill`——因此 agent 启动的任何任务，无论是后台命令、PTY 发送还是 subagent，都可以通过同一套控制读取、列出和取消。任务完成时，拥有它的 agent 会在会话内收到通知：繁忙的 agent 在下一步收到通知，空闲的 agent 则被一个 follow-up 轮次唤醒，两者均按所有者设限。加载插件还会附加让生产方能够启动后台工作的任务控制器。这些工具是基于 `ctx.jobs` 的通用 UI 卡片；配置用于调节等待超时与完成投递。
 
-- `job_output(job_id, wait?, timeout_ms?)` 默认以非阻塞方式读取。流任务只返回下一个增量；最终输出任务在终止后返回结果。每个响应都以 `[status: ...]` 结尾。`wait: true` 最多等待到配置上限，超时时仍让运行中的任务保持存活。
-- `job_list()` 以 `<id> [<kind>] <status> — <label>` 返回调用方可见的任务。
-- `job_kill(job_id, reason?)` 立即请求取消并转发已记录的原因。终止任务返回非消费式快照。
+## 目录
 
-三个工具都使用通用 UI 卡片：output 和 list 使用 `read`，kill 使用 `execute`。

-它们的规范值依次为 `{ text, job }`、`PublicJobSnapshot[]` 和 `{ outcome: 'cancellation-requested' | 'already-finished', job }`。公共快照携带 id、kind、label、status/detail 及开始／结束时间；它有意省略 `ownerSession` 和内部 `reported` 通知位。原生 renderer 保留上述状态与确认文本。
+-----
 
-当生产方提供 `outputLimitBytes` 时，`job_output`、针对已终止任务的 `job_kill` 和完成通知会在添加状态或通知文本后，对完整的原生 UTF-8 结果施加上限。只要能够容纳，读取就会保留输出尾部与控制后缀；有界完成通知则先为 `background job <id>` 和 `job_output` 收集指令预留空间，再把剩余字节用于可变的 kind、label、status、detail 与截断标记。一个前置 pre-execute 监听器会在策略运行前捕获调用方可见任务；每个任务控制定义的 final-content 回调会把其生产方上限应用到单文本拒绝、短路、规范化工具或流水线失败、替换和阻止；结构化多块策略结果保持自身形状。已有的生产方截断标记会复用，不会重复添加。省略该字段的生产方保留现有的无界控制器行为。
+<a id="use-this-package"></a>
+## 使用本包
 
-## 完成通知
+在 agent 需要启动、观察和停止后台任务的任何组合中加载本插件：它注册三个工具、附加生产方所需的控制器，并投递完成通知。它需要组合中已提供的 `ctx.tools`、`ctx.jobs` 与 `ctx.systemPrompt` 服务。
 
-一项尚未报告的完成会把 `background job <id> (<kind>: <label>) finished [status: ...]. Read its output with job_output.` 交付给确切所有者。应用上限时，即使采用 PTY 支持的 64 字节下限，稳定 id 前缀和收集命令的优先级也高于可变 label/detail，因此通知仍可操作。kill 或针对已终止任务的 read/wait 会把交付标为已报告并抑制重复通知；排空 owner 或服务的 teardown 取消同样如此。
+### 三个工具
 
-由哪条通道承载取决于所有者当时在做什么。繁忙的所有者走注入：通知进入 next-step inbox，而该 inbox 尚有内容时 turn 无法结束，因此同时结算的多个任务只花掉一步，而不是各占一轮。空闲的所有者则被 follow-up 唤醒，因为无人领取的待发通知等于模型永远不会知道的完成。`completionDelivery: quiet` 让空闲所有者也留在注入通道上，确定性 transcript 需要的正是这一点。
+- `job_output(job_id, wait?, timeout_ms?)`——读取任务输出。流任务只返回自上次读取以来的输出；最终输出任务在结算后返回其结果。每个响应都以 `[status: ...]` 结尾。除非 `wait: true`，否则读取是非阻塞的；`wait: true` 最多等待到配置上限，超时时仍让运行中的任务保持存活。
+- `job_list()`——列出你的后台任务及其 id、kind 与状态，每行一个：`<id> [<kind>] <status> — <label>`。
+- `job_kill(job_id, reason?)`——立即请求取消运行中的任务；任务在其工作真正停止后以 `killed` 结算。终止任务返回其当前快照，可选的原因会被记录并转发给任务。
 
-唤醒是有界的。每个所有者最多可通过唤醒开启 `maxConsecutiveWakes` 轮，此后的通知降级为注入；领取任何用户撰写的消息都会恢复该预算。设界是因为这条链会自激：被唤醒的一轮可能启动某个后台任务，而它的完成又会唤醒同一个所有者。本插件自己排队的通知永远不会补充它刚花掉的预算。
+三个工具依次返回 `{ text, job }`、`PublicJobSnapshot[]` 与 `{ outcome: 'cancellation-requested' | 'already-finished', job }`。公共快照携带 id、kind、label、status/detail 及开始／结束时间，并省略归属与通知簿记字段。三个工具都通过通用 UI 卡片渲染：output 和 list 用 `read`，kill 用 `execute`。
 
-一个宿主注册表可能承载本插件的多份挂载——每个 agent preset 一份。注册表会把每次结算路由给所有者 scope 链所能抵达的监听器，因此某个 preset 下的挂载永远看不到另一个 preset 的 agent，无论挂载了多少 preset，一个 agent 每次完成都只读到一条通知。同一套路由也决定本挂载的控制器服务哪些 agent：组合中未加载 `tool-jobs` 的 agent 根本无法启动后台工作。
+### 完成通知
 
-## 配置
+任务完成时，拥有它的 agent 会收到会话内消息 `background job <id> (<kind>: <label>) finished [status: ...]. Read its output with job_output.`。繁忙的 agent 会在下一步收到注入的通知——inbox 尚有内容时轮次无法结束，因此同时结算的多个任务只花掉一步，而不是各占一轮。空闲的 agent 则被一个 follow-up 轮次唤醒，因为无人领取的通知等于模型永远不会知道的完成。kill 或针对终止任务的 read/wait 会把完成标为已报告并抑制重复通知；排空 owner 或服务的 teardown 取消同样如此。
 
-| key | 默认值 | 含义 |
+唤醒是有界的：每个所有者最多可被唤醒 `maxConsecutiveWakes` 次，此后的通知降级为注入；领取任何用户撰写的消息都会恢复预算。设界是因为这条链会自激——被唤醒的一轮可能启动某个后台任务，而它的完成又会唤醒同一个所有者。`completionDelivery: quiet` 让空闲所有者也在注入通道上，确定性 transcript 需要的正是这一点。
+
+### 最小配置
+
+不带配置加载插件是常用路径；`waitTimeoutMs` 高于 `maxWaitTimeoutMs` 时会在加载时失败。
+
+```yaml
+- name: '@deepseek-ai/dsh-tool-jobs'
+```
+
+| 字段 | 默认值 | 含义 |
 |---|---|---|
-| `waitTimeoutMs` | `30000` | `wait: true` 省略 `timeout_ms` 时使用的等待时间 |
-| `maxWaitTimeoutMs` | `600000` | 模型所给等待时间的上限 |
+| `waitTimeoutMs` | `30,000` | `wait: true` 省略 `timeout_ms` 时使用的等待时间 |
+| `maxWaitTimeoutMs` | `600,000` | 模型所给等待时间的上限；更大的值向下收敛到它 |
 | `completionDelivery` | `wakeup` | `wakeup` 为空闲所有者开启一轮；`quiet` 让通知继续待领 |
 | `maxConsecutiveWakes` | `3` | 一个所有者可由唤醒开启的轮数，超出后通知降级为注入 |
 
-默认值高于上限时，插件会在加载时失败。
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-tool-jobs)是每个受支持字段及其 JSDoc 的穷尽式真源。
 
+### 可能出什么问题
+
+组合中未加载 `tool-jobs` 的 agent 无法启动后台工作：本插件的控制器正是生产方 `ctx.jobs.start()` 得以启用所依赖的。模型给出的等待时间超过 `maxWaitTimeoutMs` 时会向下收敛到上限，超时的等待返回 `[status: running]` 并让任务保持存活，而不是失败。待领于空闲所有者的完成通知无法在该所有者释放后存活。

+## 理解实现
+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释工具背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+- **与 kind 无关的控制。** 同一套三个工具读取、列出和取消每种生产方 kind 的任务——bash、subagent、PTY——因为它们都通过通用的 `ctx.jobs` 运行时注册。
+- **投递归本插件，收件人归注册表。** 插件决定未报告的完成如何到达所有者——注入繁忙的一步，或唤醒空闲所有者的一轮——而注册表把每次结算路由给其所有者 scope 链所能抵达的监听器，因此某个 preset 下的挂载永远看不到另一个 preset 的 agent，无论挂载了多少 preset，一个 agent 每次完成都只读到一条通知。
+- **生产方自有的输出上限。** 生产方提供 `outputLimitBytes` 时，完整的模型侧结果——输出读取、终止 kill 快照或完成通知——会在添加状态与通知元数据之后被施加上限；省略该字段的生产方保持无界行为。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：工具注册、完成监听器、提示词区段、输出上限 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；执行关系归能力 seam 所有） |
+
+### 输出上限
+
+`job_output` 与 `job_kill` 会在策略运行前于前置的 pre-execute 监听器中捕获调用方可见任务，因此生产方上限适用于完整渲染结果。`job_output` 在策略保留默认渲染时保持其输出／状态拆分，对输出尾部与 `[status: ...]` 后缀设界；其他单文本结果——拒绝、短路、规范化工具或流水线失败、替换与阻止——按单个文本设界，而结构化多块策略结果保持自身形状。有界完成通知先为稳定的 `background job <id>` 前缀与 `job_output` 收集指令预留空间，再把剩余字节用于可变的 kind、label、status、detail 与截断标记，因此在 PTY 支持的 64 字节下限下通知仍可操作；已有的生产方截断标记会被复用，不会重复添加。
+
+### 通知投递通道
+
+`onJobDone` 跳过已报告或无所有者的任务。`wakeup` 投递在预算内为空闲所有者开启一轮，按确切 `Agent` 记录在 `WeakMap` 中；领取用户撰写的消息（`agent/inbox/claimed`）会重置该所有者的预算。繁忙的所有者——或超出预算的任何通知，以及 `quiet` 投递——改为注入 next-step inbox。teardown 结算抵达时已标记为 `reported`，因此释放永远不会花一次模型请求来宣布无人能读的通知。

 # llm/ — LLM capability family
 
 English | [中文](README.zh.md)
 
-The LLM seam, provider adapters, and provider-specific request metadata plugins. The `llm` package owns both the Service Definition and Consumer roles: the abstract service, content-block vocabulary, and stream-chunk assembler. Provider adapters register on `ctx.llm`. All **product** packages.
+## Summary
+
+The llm group provides the harness's model-call capability: one provider-neutral service through which any composition streams requests to a model provider, plus adapters, provider-specific request metadata, retry execution, and measurement. The core `llm` package defines the message, content-block, and stream-chunk vocabulary every plugin and the session log use; provider adapters translate a provider's wire format into that vocabulary; DeepSeek request-extension plugins contribute lifecycle-owned metadata outside model input; `llm-retry` re-runs failed requests at durable agent-step boundaries; and `token-meter` measures request and context pressure from the durable log. This page maps the group; each package README owns its per-package contract.

 # @deepseek-ai/dsh-llm-deepseek
 
 English | [中文](README.zh.md)
 
-DeepSeek chat-completions adapter for the harness LLM seam: direct `fetch` + SSE (framed by `eventsource-parser`) translating the official wire format (source of truth: the API docs — guides/thinking_mode, guides/tool_calls, api/create-chat-completion) into the `StreamChunk` protocol.
+## Summary
 
-A second, library-backed implementation of the same seam exists in `@deepseek-ai/dsh-llm-pi-ai`. This package owns the `deepseek-official` provider route — deliberately distinct from pi-ai's catalog name `deepseek`, so one composition can mount both DeepSeek paths side by side; registering another adapter for `deepseek-official` itself still throws `LlmError('DUPLICATE_ADAPTER')`.
+`@deepseek-ai/dsh-llm-deepseek` is the direct DeepSeek adapter for the harness LLM service: it owns the `deepseek-official` provider route and translates DeepSeek's chat-completions wire format into the harness stream-chunk protocol. With it a composition can stream DeepSeek models with configurable thinking and reasoning effort, send images to vision models, and browse an advisory model catalog. Connection facts — endpoint, catalog, key, thinking policy — resolve per request, so editing the user settings document changes the next request without a restart. It is one of two structurally different adapters for DeepSeek: the pi-ai twin serves its own route names through a library and additional providers, and both can be mounted side by side.
 
-The package root exposes the Cordis plugin contract and `DeepSeekAdapter`; wire serialization, SSE parsing, and chunk translation helpers are not part of that root contract.

+## Use this package
+
+Mount this plugin when a composition streams DeepSeek models through the harness LLM service. It registers the single `deepseek-official` route and resolves connection facts per request, so a composition entry plus an optional user settings section drive the whole adapter.
+
+### When to choose it
+
+Choose this adapter when the deployment targets DeepSeek's official API, optionally behind an OpenAI-compatible gateway named by `baseURL`. Choose `dsh-llm-pi-ai` when the same composition also routes other providers or hand-declared gateways through pi-ai's catalogs; the two adapters can be mounted together because their route names do not collide. Registering any other adapter for `deepseek-official` fails with `DUPLICATE_ADAPTER`.

-The plugin registers the single provider route `deepseek-official` together with its resolved `retryPolicy`; omission resolves to normal mode with five retries. A request selects it with `provider: deepseek-official`; its `model` is passed through as the wire `model` string, so changing DeepSeek models does not require lifecycle-time registration. Omitting `models` advertises `deepseek-v4-flash` as the fast, economical choice for focused work, `deepseek-v4-pro` as the stronger, higher-cost choice for complex or quality-critical work, and the image-capable `deepseek-v4-flash-vision-exp`; each has a 1,000,000-token context window. An explicit list replaces those defaults, while `models: []` advertises none. Catalog entries are exposed through `ctx.llm.listModels('deepseek-official')` for clients such as ACP editors, the Web selector, and model discovery tools, but remain advisory: unlisted model ids still pass through unchanged as text-only routes. An omitted entry name defaults to its id, and omitted `inputModalities` means `text` only.
+A request selects the route with `provider: deepseek-official`; the model id passes through to the wire, so new DeepSeek models need no re-registration. Omitted `models` advertises `deepseek-v4-flash` as the fast, economical choice for focused work, `deepseek-v4-pro` as the stronger, higher-cost choice for complex or quality-critical work, and the image-capable `deepseek-v4-flash-vision-exp`; each has a 1,000,000-token context window. An explicit list replaces those defaults, and unlisted model ids still pass through as text-only routes. Clients, including model discovery tools, can read the advisory entries through `ctx.llm.listModels('deepseek-official')`. Image-capable entries may set `imagePixelBudget` to a positive integer or `low`, and may set `imageMaxBytes`.
 
-An image-capable catalog entry declares `inputModalities: [text, image]` and may set `imagePixelBudget` to an exact positive integer or `low`; omission uses 640,000 total pixels, while `low` selects 512 by 512 total pixels. `imageMaxBytes` defaults to 1MiB. The attachment store scales by `min(1, sqrt(pixelBudget / (width * height)))` and rounds inward to keep the pixel count at or below the hard cap, so a 2048 by 1024 normalized attachment becomes about 1130 by 565 instead of a forced square. Request encoders run lazily: alpha images try WebP (effort 0) at 85, 75, then 60, and opaque images try JPEG at those qualities; when every quality exceeds 1MiB the smallest output is used. Concurrent generation of one `variantId` shares one transform. A caller can cancel its own wait without interrupting other waiters; the transform stops when no waiter remains. The adapter normally uploads the exact derived request bytes through `POST /files` and sends `{type: "file", file_id}` blocks. A failed or timed-out file-id resolution rebuilds the whole chat request with those same request versions as base64 data URLs; one request never mixes file ids and inline images. Every retained image is preceded by text naming the complete attachment id and actual request dimensions. When the attachment provider exposes a host object and the current filesystem maps it into the tool execution world, the text also includes that read-only path and the matching extension for a writable copy. This access is resolved independently from the deterministic request version and its `variantId`. The descriptor states that the preview and normalized image may differ from the upload. User, tool-result, agent-loop, compaction, and direct `ctx.llm.stream` requests all use this projection. Text-only routes receive stable attachment placeholders while durable history keeps its image references.

-`maxRequestFilesBytes` and `maxImagesPerRequest` bound the retained request versions at 128MiB and 600 images by default. The byte and count quanta must not exceed their corresponding bounds. Before attachment reads, the adapter uses each route's request-version byte cap as a conservative upper bound and removes the oldest over-budget prefix; only retained normalized attachments are read and transformed. Exact derived lengths are checked again without restoring omitted images. When the byte bound is crossed, the oldest prefix advances past the next 64MiB boundary; 129 one-megabyte images remove the oldest 65 and retain 64MiB, and that prefix stays unchanged until durable history exceeds 192MiB. Count overflow advances independently in `imageOffloadCountQuantum` steps. Each removed image becomes its own model-visible placeholder with its display name or attachment id and, when available, normalized dimensions, media type, and current read-only local path. This high-watermark projection avoids changing an old request prefix after every new image.
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-llm-deepseek) is the exhaustive source for every accepted field and its JSDoc.
 
-Inline fallback has an independent base64 budget. `maxInlineRequestImageBytes` defaults to 20MiB and `inlineImageOffloadByteQuantum` to 10MiB, so a history of 21 one-megabyte base64 payloads removes the oldest 11 and retains 10MiB. The calculation uses base64-expanded lengths. The prepared request versions are reused byte-for-byte; fallback does not decode or compress an image again. Successful mappings created before a later image fails remain indexed for future requests.
+### Streaming with thinking and images
 
-Uploaded ids are indexed below `DSH_HOME` by endpoint/API-key scope and request `variantId`. The variant covers the normalized attachment id, transform version, route pixel and byte budgets, and encoder parameters, so Files API and inline fallback refer to the same deterministic bytes. Uploads request a seven-day lifetime by default and store the server's `expires_at`. A local mapping with no more than one hour remaining is replaced before use; the adapter does not retrieve every remote file before chat. If chat reports expired, deleted, missing, or invalid file ids and names one or more ids used by the request, the adapter removes exactly those mappings. If the provider identifies stale file state without naming an id, it removes every file mapping used by that chat attempt. It then uploads the affected request versions again and retries chat once. A second stale-file rejection clears the mappings identified by that response and is returned without a third chat attempt. An upload response without a complete file object, matching byte count, and `expires_at` is never indexed; a later request therefore uploads again instead of trusting inconsistent local state. A malformed local upload index is treated as an empty cache and replaced by the next successful upload. File resolution, including local index access and remote upload, has a per-image one-minute deadline by default. The default five-minute stream idle deadline therefore leaves time for inline fallback; a deployment may configure a shorter stream idle deadline when it wants that outer deadline to terminate the request first. Each successful resolution refreshes the outer idle watchdog. Any resolution failure switches that request to inline mode, while explicit public file-management operations continue to report their own failures.
+An image-capable route resolves each durable reference into a deterministic request version under its pixel and byte budgets. `imagePixelBudget` accepts a positive integer or `low`; omission uses 640,000 total pixels, `low` uses 512×512 total pixels, and `imageMaxBytes` defaults to 1 MiB. Alpha images use WebP effort 0 and opaque images use JPEG on the 85/75/60 quality ladder, keeping the smallest output when every candidate exceeds the target. Every retained image is preceded by text naming its complete attachment id and actual request dimensions. When the current filesystem maps the attachment provider's host object, that text also carries a read-only execution-world path and the extension for a writable copy. Text-only and unlisted routes receive stable attachment placeholders while durable history keeps the image references.
 
-Concurrent resolution of one scoped `variantId` shares one Files upload with waiter-local cancellation. One quota upload failure first paginates and collects the configured number of oldest `dsh-` files, then deletes that set before one upload retry. `DeepSeekFilesClient.delete`, `DeepSeekFileStore.release`, and `releaseAll` expose explicit remote-space reclamation. The current provider limits represented by this package are 128MiB per Files upload, 32MiB per chat-referenced image, 10,000 stored files, and 25GiB per API key; the default 1MiB request version remains below the two per-file limits.
+The adapter normally uploads those exact request bytes through the DeepSeek Files API and sends file-id blocks. A failed or timed-out file resolution rebuilds the whole chat request with the same request versions as base64 data URLs; one request never mixes file ids and inline images. Cached ids are scoped by endpoint and API key, refreshed before expiry, invalidated from provider stale-file errors, and resolved through singleflight with waiter-local cancellation. Quota failure deletes one configured batch of the oldest harness-owned files before one upload retry.
 
-`contextWindow` is optional per configured model and is not exposed through the advisory catalog. `ctx.llm.resolveModelInfo('deepseek-official', model).context` returns an exact model value first, then `defaultContextWindow` for an entry without capacity or an unlisted pass-through id. The adapter default is 1,000,000; pressure-sensitive plugins therefore get deployment-owned capacity without treating the model selector as authoritative. Registering another adapter for `deepseek-official` throws `LlmError('DUPLICATE_ADAPTER')`.
+Files mode bounds retained request versions by `maxRequestFilesBytes` and `maxImagesPerRequest`; inline fallback has its own base64 budget. Both remove an oldest prefix in configured byte or count quanta. Each omitted image gets its own model-visible placeholder with its display name or attachment id and, when available, normalized dimensions, media type, and current read-only path. The stepped high-watermark policy avoids rewriting an old request prefix after every new image.
 
-`maxTokens` is the adapter-configured output cap for conversation requests and defaults to 256,000. A catalog entry may carry its own `maxTokens`, which wins for that model; an entry without one, and any unlisted pass-through id, resolve to the profile value, so adding a per-model cap changes one model rather than the route. Exact-model resolution exposes the winner as `defaultMaxTokens`; `LlmRuntime` materializes that value into `GenerateOptions.maxTokens` before the agent loop writes `request/header`, so the wire request remains reconstructable. An explicit request or `AgentOptions.maxTokens` value wins and is serialized as `max_tokens`. The adapter does not clamp this request budget against `contextWindow`; deployments with a smaller context or provider output limit must configure a compatible `maxTokens`.
+`reasoningEffort` selects the advertised default. Exact-model metadata exposes ordered `off`, `low`, `high`, and `max` efforts with selection guidance when deployment policy permits thinking. `low`, `high`, and `max` enable thinking and serialize as `reasoning_effort`, while adapter-owned `off` sends `thinking.type: disabled` instead. An unsupported value fails with `UNSUPPORTED_REASONING_EFFORT` before network I/O, and `thinking: disabled` rejects any non-`off` effort at plugin load. Requests with `purpose: 'session-title'` force thinking off to reserve output for visible title text.
 
-The same exact-model result exposes ordered `off`, `low`, `high`, and `max` efforts with selection guidance under `reasoning` for every pass-through model when deployment policy permits thinking. `reasoningEffort` selects the advertised default and falls back to `high` when omitted. `agent/request` can replace it on each conversation step; the resolved value is logged in `request/header`. `low`, `high`, and `max` enable thinking and serialize as the same official top-level `reasoning_effort` value; adapter-owned `off` instead serializes `thinking.type: disabled` and omits `reasoning_effort`. An unsupported value fails with `UNSUPPORTED_REASONING_EFFORT` before network I/O.
+### Dynamic configuration
 
-`thinking: disabled` is a deployment lock that publishes only `off` with `off` as its default. Omitting `reasoningEffort` or configuring it as `off` is valid; configuring `low`, `high`, or `max` fails plugin loading, and a direct per-request attempt to enable thinking fails before network I/O. A request with `GenerateOptions.purpose: 'session-title'` also forces thinking disabled and omits the already-resolved effort, reserving its bounded output for visible title text without changing conversation or compaction defaults.
+Connection facts are re-read once per operation through the optional settings and credentials seams. A `llm-deepseek:` section in the user settings document overrides any field without a restart; a snapshot that fails a beyond-schema bound keeps the last good facts and logs the failure. The API key resolves per stream call from the same snapshot that supplies the endpoint, image and Files policies, and idle budget, so a rejected settings generation contributes none of them. Image requests resolve the attachment service at request time, so load order does not freeze image availability.
 
-`streamIdleTimeoutMs` bounds each outstanding provider read, including the initial `fetch`, without counting time the consumer spends between chunks. DeepSeek SSE comments and successful file resolutions rearm an outstanding read as transport activity but never become `StreamChunk` values or session-log events. One stable abort signal reaches the request and body reader for the whole call; expiry stops the transport and throws `LlmError('TIMEOUT')`, while an earlier caller abort throws `LlmError('ABORTED')`. The adapter normally makes one chat request per `stream()` call and makes a second only for stale-file recovery. A file-resolution failure before the first chat sends one inline request. If replacement resolution fails after a stale-file response, the inline request is the one permitted retry. It registers the configured retry policy as provider metadata, and `dsh-llm-retry` separately executes that policy at durable agent-step boundaries.
+### Provider-specific request fields
 
-## Dynamic configuration (settings + credentials)
+When `ctx.deepseekLlmApiExtensions` is present, the adapter prepares its registered top-level fields from the exact serialized base request before `fetch`. Preparation or field collisions fail before HTTP; after a 2xx response, the adapter accepts every captured contribution before consuming SSE. Transport and non-2xx failures do not accept them. Shipped compositions use this for the optional incremental `dsh_session_log` field and the default-on active `dsh_plugin_packages` inventory; both stay outside model input.
 
-Connection facts are not frozen at load. `resolveAdapterOptions` is the one explicit resolve step from raw config to validated facts, and the adapter re-reads them through a thunk **once per operation**: base URL, catalog, request defaults, image and Files policies, and idle budget all take effect on the next request, while an in-flight stream keeps the facts it started with. Three optional seams feed that thunk:
+### Failures and recovery
 
-- **`ctx.settings`** — the plugin registers the `llm-deepseek` namespace with this same `Config` schema and its `cordis.yml` entry as the composition `base`, so a `llm-deepseek:` section in the user settings document overrides any field without a restart. Without a mounted settings service the entry config alone drives the adapter, unchanged. A live settings snapshot that passes the schema but fails a beyond-schema bound (a duplicate catalog id, a broken thinking/effort pair) keeps the last good facts and logs the failure; the entry config itself still fails plugin load.
-- **`ctx.credentials`** — the API key resolves per stream call, from the *same* resolved snapshot that supplies the endpoint. Configuration carries only `apiKeyEnv`, never a literal key: the reference resolves through the credential seam, and without a mounted seam through the trusted environment layers. Because credential facts travel with the connection facts, a settings snapshot the resolver rejects contributes neither its endpoint nor its key: the whole previous generation keeps serving. Every resolved key is format-checked before use, so a value no HTTP header can carry is refused with `LlmError('INVALID_CREDENTIAL')` naming the failing entry point — never any part of the key — instead of surfacing as an opaque `fetch` `TypeError`. A request with no key anywhere fails with `MISSING_CREDENTIAL` naming every configuration entry point, while the route stays registered and the catalog stays browsable — first-run onboarding is "browse models, store the key, prompt again", with no restart between.
-- **`ctx.attachments`** — image requests resolve this service at request time, so Cordis load order does not freeze optional image availability. Absence rejects image input with `UNSUPPORTED_CONTENT`; text-only calls do not require the service.
+Non-2xx responses fail with stable codes: `AUTH` (401/403), `QUOTA`, `RATE_LIMIT`, `CONTEXT_WINDOW_EXCEEDED`, `INVALID_REQUEST`, `SERVER`, and `HTTP_<status>` otherwise; pre-response transport failures throw `TRANSPORT`, caller aborts throw `ABORTED`, and stream-idle expiry throws `TIMEOUT`. Request-extension preparation, field collision, or post-2xx acceptance fails with `REQUEST_EXTENSION`. A normalized-image rejection names every plausible attachment and its durable position when the provider does not identify a file id. Stale-file rejection invalidates the named mappings (or every mapping used by the attempt) and permits one replacement chat attempt. Protocol violations throw `STREAM_CLOSED` or `MALFORMED_RESPONSE`, and a terminal `stop` with no content blocks becomes `EMPTY_RESPONSE`, which the default retry policy retries. A request with no key anywhere fails with `MISSING_CREDENTIAL`, and a malformed credential fails with `INVALID_CREDENTIAL` naming the reference to fix — never any part of the key.
 
-The one registration-captured fact is the retry policy: when its resolved value changes, the plugin re-registers the route in place (same adapter instance, one synchronous section), so `ctx.llm.providerRetryPolicy('deepseek-official')` always reports the current policy.
+-----
 
-The plugin also declares its route in the configurable-provider directory (`ctx.llm.listConfigurableProviders()`): provider `deepseek-official`, settings namespace `llm-deepseek`, empty settings path — the whole section is the profile. Configuration surfaces use that entry to offer this adapter alongside dormant pi-ai providers.

-When `ctx.deepseekLlmApiExtensions` is present, the adapter prepares its registered top-level fields after serializing the exact wire messages and before `fetch`. The same request signal reaches providers, and cancellation stops waiting even when a provider ignores it. Preparation failures and field collisions fail before HTTP with `REQUEST_EXTENSION`. After HTTP 2xx, the adapter awaits the prepared acceptance transaction before consuming the SSE body; an acceptance failure uses the same code, while transport and non-2xx failures do not accept the fields. Fields go to the resolved `baseURL`, including a configured gateway. A composition without the registry sends the base DeepSeek request unchanged.
+This section explains the design behind the adapter; the observable behavior is fully covered in [Use this package](#use-this-package).
 
-Shipped profiles and runnable examples mount [`@deepseek-ai/dsh-session-log-deepseek`](../../session/session-log-deepseek/README.md) for the incremental `dsh_session_log` field and [`@deepseek-ai/dsh-plugin-package-inventory-deepseek`](../plugin-package-inventory-deepseek/README.md) for the complete active `dsh_plugin_packages` field. Session-log upload defaults off and requires `session-log-deepseek.enabled: true`; package metadata defaults on. Both remain model-hidden. `llm-pi-ai` neither imports nor calls this provider-specific registry.
+### Design philosophy
 
-## App attribution
+The plugin is built on one explicit resolve step and one registration fact. `resolveAdapterOptions()` is the single path from raw config to validated connection facts, and the adapter re-reads those facts through a thunk once per operation — base URL, catalog, request defaults, image and Files policies, and idle budget all take effect on the next request, while an in-flight stream keeps the facts it started with. The only fact captured at registration is the retry policy: when its resolved value changes, the plugin re-registers the route in place, in one synchronous section, so no request observes a gap.
 
-Every chat and Files API request carries the shared attribution header from dsh-llm's `attributionHeaders()`, the mandatory `User-Agent` baseline identifying the harness (see [dsh-llm § App attribution](../llm/README.md#app-attribution-attributionts)). Direct DeepSeek requests and OpenAI-compatible gateway requests get no provider-specific app-attribution headers under this adapter contract; OpenRouter app attribution is deferred to a future explicit OpenRouter adapter or mode. A request whose `GenerateOptions.purpose` is `compaction` (dsh-compaction-basic's auxiliary summarization call) additionally carries `x-deepseek-harness-compact: 1`, so the host can separate compaction traffic from conversation requests.
+### Source map
 
-DeepSeek request identity is separate from app attribution. After credential resolution, every provider request carries `x-deepseek-harness-user-id` with the stable anonymous id from [`@deepseek-ai/dsh-anonymous-user-id`](../../identity/anonymous-user-id/README.md); a request carrying `GenerateOptions.sessionId` also sends that exact value as `x-deepseek-harness-session-id`, while a direct call without a session omits the session header. Both headers go to the resolved `baseURL`, including a configured gateway, and remain outside the request body and model-visible content.

-## Wire-format notes
+### Wire flow
 
-- Streaming only (`stream_options.include_usage` always on). `usage` may arrive attached to the finish chunk or as a trailing usage-only chunk — the translator defers both to `[DONE]`, so `usage` always precedes `finish` and nothing follows `finish`.
-- The adapter-owned `off` effort maps to `thinking: {type: 'disabled'}` and never crosses the wire as `reasoning_effort: 'off'`.
-- The first thinking-mode chunk carries `reasoning_content: ""` — handled (no spurious reasoning block).
-- **Reasoning passback rule**: every assistant turn that carried reasoning serializes `reasoning_content` back in history. Thinking mode requires it on tool-call turns; DeepSeek ignores it elsewhere, while a gateway re-encoding the conversation for another vendor recovers that turn's upstream thinking signature by hashing the replayed text.
-- Image-capable user messages preserve text/image order. Tool-role content remains a string; consecutive tool-result images are grouped into the following user message with `Attached image(s) from tool result:`.
-- Token accounting: `cacheReadTokens` ← `prompt_cache_hit_tokens` / `prompt_tokens_details.cached_tokens`; DeepSeek reports no cache-write metric. `totalTokens` is the exact `prompt_tokens + completion_tokens` aggregate and is omitted if a supplied `total_tokens` disagrees.
+One `stream()` call normally makes one chat request: resolve deterministic request images, prefer Files ids, prepare any registered top-level request extensions, fetch from the resolved `baseURL`, accept extension transactions after HTTP 2xx, and translate the SSE stream into the harness protocol. File-resolution failure makes the first chat inline; a provider stale-file response permits one replacement attempt, also inline if replacement resolution fails. Every chat and Files call carries shared attribution plus the stable anonymous user id outside model input, and a session call also carries its session id. Reasoning history is serialized back when required, and cache accounting maps DeepSeek's cache-hit metrics into harness usage.
 
-## Errors
+</details>
 
-Non-2xx responses throw `LlmError` with stable codes: `AUTH` (401/403), `QUOTA` (a response whose provider details identify exhausted quota, balance, or credits), `RATE_LIMIT` (other 429s), `CONTEXT_WINDOW_EXCEEDED` (a 400 whose provider code, type, or message identifies context overflow), `INVALID_REQUEST` (other 400s and 413), `SERVER` (5xx), `HTTP_<status>` otherwise. Its serializable `failure` retains the HTTP status plus a valid positive `Retry-After` seconds/date delay and `x-request-id` / `x-deepseek-request-id` when present. Extension preparation, base-field collision, or post-2xx acceptance fails with `REQUEST_EXTENSION`; no extension failure is relabelled as transport. If DeepSeek rejects a normalized image, the primary message names the attachment or display name, durable message and image position, normalized media type, 8-bit sRGB/sRGBA depth, dimensions, and provider message. With several candidates and no file id in the provider detail, it lists each possible image instead of assigning the failure to the first one. The raw response remains the error `cause`; it is never the only user-visible diagnostic. Attachment reads retain their stable attachment failure code rather than becoming transport failures. A pre-response transport failure (DNS, refused connection, TLS, proxy) throws `TRANSPORT` naming the configured endpoint and chaining the original rejection as `cause`; caller aborts throw `ABORTED`, and the loop's cancellation signal remains authoritative. Protocol violations throw `STREAM_CLOSED` (no `[DONE]`) or `MALFORMED_RESPONSE` (bad JSON payload). Unknown wire `finish_reason`s (e.g. `content_filter`, `insufficient_system_resource`) become `finish {kind: 'error', failure}` chunks, and a completed stream whose `stop` (or absent) finish opened no content blocks becomes a `finish {kind: 'error'}` with code `EMPTY_RESPONSE` (retried by default policy).

 ## Model Experience
 
 ### DeepSeek request
 
 #### What the model sees
 
-The selected DeepSeek model receives the harness system prompt, message history, tool schemas, stop sequences, and call config without adapter-authored prompt prose. Provider-specific request extension fields remain outside that model input. The vision model normally receives retained user and tool-result images as Files API references beside attachment handles and request-preview dimensions. It also receives a normalized-object path when the current execution filesystem maps the attachment provider's host object; a Files resolution failure sends all retained images as inline data URLs instead. The descriptor tells the model that this read-only local copy may be resized or re-encoded and must not be used to infer upload properties. An over-budget older image keeps the access currently resolved for that request in its per-image placeholder. Reasoning content from a prior assistant turn is passed back verbatim, whether or not that turn called a tool.

 #### Token effect
 
-Provider tokenization governs exact text and image-token input. The adapter additionally declares per-route request-image pricing (`imageRequestPricing`): it reproduces the request projection's oldest-first offload from durable byte lengths and prices each retained image with the published v4 vision accounting (14px patch grid, 3:1 downsampling, 384-token cap, worst-case alignment pad) at its projected request dimensions, so the token meter can price image pressure before a request is sent; reported usage remains authoritative. Reasoning passback carries every reasoned turn's chain of thought into later requests, while dropping over-budget images avoids paying those tokens again; cache-read usage is reported when available.

 #### KV Cache effect
 
-An unchanged assembled prefix is eligible for DeepSeek cache reuse, which this adapter reports in usage. Deterministic request-image bytes do not make the complete prefix immutable: a changed execution-world path rewrites historical descriptor text even without offload, a refreshed upload can replace a `file_id`, and Files-to-base64 fallback changes the image representation. Any of these may prevent reuse from the first affected image. Model-route, prompt, schema, history, and image-budget changes have the same suffix effect; reasoning passback appends on every reasoned turn.

-harness LLM（大语言模型）seam 的 DeepSeek chat-completions 适配器：直接 `fetch` + SSE（Server-Sent Events，由 `eventsource-parser` 分帧），将官方协议格式（wire format；真源：API 文档 guides/thinking_mode、guides/tool_calls、api/create-chat-completion）转换为 `StreamChunk` 协议。
+## 概述
 
-同一 seam 的第二个基于库的实现位于 `@deepseek-ai/dsh-llm-pi-ai`。本包拥有 `deepseek-official` 提供方路由——刻意区别于 pi-ai 的 catalog 名称 `deepseek`，因此同一组合可以并排挂载两条 DeepSeek 路径；而为 `deepseek-official` 本身注册另一个适配器仍会抛出 `LlmError('DUPLICATE_ADAPTER')`。
+`@deepseek-ai/dsh-llm-deepseek` 是 harness LLM 服务的 DeepSeek 直连适配器：它拥有 `deepseek-official` 提供方路由，并把 DeepSeek 的 chat-completions 协议格式翻译为 harness 的流式分片协议。借助它，组合可以流式调用 DeepSeek 模型，支持可配置的 thinking 与推理（reasoning）强度、向视觉模型发送图片，并浏览一份建议性模型目录。连接事实——端点、目录、密钥、thinking 策略——按请求解析，因此编辑用户设置文档即可改变下一个请求，无需重启。它是 DeepSeek 的两个结构不同适配器之一：pi-ai 孪生通过库与更多提供方服务自己的路由名，两者可以并排挂载。

-该插件注册唯一提供方路由 `deepseek-official`，并一同注册解析后的 `retryPolicy`；省略时会解析为 normal 模式并重试五次。请求使用 `provider: deepseek-official` 选择该路由；其 `model` 会作为协议 `model` 字符串原样传递，因此更改 DeepSeek 模型不需要生命周期时注册。省略 `models` 会公布适合聚焦任务、快速且经济的 `deepseek-v4-flash`，适合复杂或质量关键任务、更强但成本更高的 `deepseek-v4-pro`，以及支持图片输入的 `deepseek-v4-flash-vision-exp`；三者的上下文窗口均为 1,000,000 token。显式列表会替换这些默认值，`models: []` 则不公布任何模型。Catalog 配置项通过 `ctx.llm.listModels('deepseek-official')` 公开给 ACP（Agent Client Protocol）编辑器、Web 选择器和模型发现工具等客户端，但仍只提供建议：未列出模型 id 仍原样传递，并按纯文本路由处理。省略配置项 name 默认为其 id，省略 `inputModalities` 则表示仅支持 `text`。
+请求用 `provider: deepseek-official` 选择路由；模型 id 原样传到协议，因此新增 DeepSeek 模型无需重新注册。省略 `models` 时会公布适合专注任务、快速且经济的 `deepseek-v4-flash`，适合复杂或质量关键任务、能力更强且成本更高的 `deepseek-v4-pro`，以及支持图像的 `deepseek-v4-flash-vision-exp`；每个模型都有 1,000,000 token 上下文窗口。显式列表会替换这些默认值，未列出的模型 id 仍作为纯文本路由原样通过。包括模型发现工具在内的客户端可通过 `ctx.llm.listModels('deepseek-official')` 读取这些建议性条目。支持图片的条目可把 `imagePixelBudget` 设置为正整数或 `low`，也可以设置 `imageMaxBytes`。
 
-支持图片的 catalog 配置项声明 `inputModalities: [text, image]`，并可把 `imagePixelBudget` 设为确切正整数或 `low`；省略时使用总像素 640,000，`low` 选择总像素 512×512。`imageMaxBytes` 默认值为 1MiB。附件存储按 `min(1, sqrt(pixelBudget / (width * height)))` 缩放，并向预算内取整，确保总像素不超过硬上限。因此 2048×1024 规范化附件会得到约 1130×565 的请求版本，而不会被强制变成正方形。请求编码按需执行：透明图片依次尝试质量 85、75、60 的 WebP（effort 0）；非透明图片依次尝试这些质量的 JPEG。全部质量档都超过 1MiB 时使用其中最小的产物。同一 `variantId` 的并发生成共享一次变换。调用方可以单独取消等待，不会中断其他等待方；没有等待方时才会停止变换。适配器通常通过 `POST /files` 上传确切的派生请求字节，再发送 `{type: "file", file_id}` 块。File ID 解析失败或超时后，适配器会用相同请求版本的 base64 data URL 重新组装整个 chat 请求；同一请求不会混用 file ID 和内联图片。每张保留图片前都有文本，写明完整附件 ID 和实际请求尺寸。附件提供方给出宿主对象且当前文件系统能够将其映射到工具执行环境时，文本还会给出该只读路径，并指出复制到可写路径时应使用的匹配扩展名。该访问方式独立于确定性的请求版本及其 `variantId`。描述也会说明预览和规范化图片可能与上传图片不同。User、工具结果、agent loop、压缩和直接 `ctx.llm.stream` 请求都使用该投影。纯文本路由会收到稳定的附件占位文本，持久历史继续保留图片引用。

-`maxRequestFilesBytes` 和 `maxImagesPerRequest` 限制请求中保留的请求版本，默认值分别为 128MiB 和 600 张。字节和数量步长不得超过对应上限。读取附件前，适配器以路由的请求版本字节上限作为保守上界，移除超预算的最旧前缀，只读取并转换保留的规范化附件。系统随后用确切派生长度再次检查，但不会重新加入已省略图片。字节数越过上限时，被移除的最旧前缀会越过下一个 64MiB 边界。由 1MiB 图片组成的历史达到 129MiB 时会移除最旧的 65 张并保留 64MiB；直到持久历史超过 192MiB，这个前缀才再次变化。图片数量超限时则按 `imageOffloadCountQuantum` 独立递增。每张被移除的图片都有自己的模型可见占位文本，其中包含显示名称或附件 ID；如果当前提供方支持，还会包含规范化尺寸、媒体类型和当前只读本地路径。这种定量投影不会因每新增一张图片就改写较早的请求前缀。
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-llm-deepseek)是每个受支持字段及其 JSDoc 的穷尽式真源。
 
-内联回退使用独立的 base64 预算。`maxInlineRequestImageBytes` 默认为 20MiB，`inlineImageOffloadByteQuantum` 默认为 10MiB，因此由 21 个 1MiB base64 负载组成的历史会移除最旧的 11 个并保留 10MiB。计算使用 base64 膨胀后的长度。系统逐字节复用已经准备好的请求版本；回退不会再次解码或压缩图片。前面图片已经成功写入的上传映射会保留，供后续请求复用。
+### 带 thinking 与图片的流式调用
 
-上传 ID 按端点和 API key 作用域以及请求 `variantId` 记录在 `DSH_HOME` 下。变体身份覆盖规范化附件 ID、变换策略版本、路由像素和字节预算及编码参数，因此 Files API 和内联回退引用同一份确定性字节。上传默认请求 7 天有效期，并保存服务端返回的 `expires_at`。本地映射剩余时间不超过一小时时会在使用前替换；适配器不会在每次 chat 前查询远端文件。如果 chat 报告文件 ID 已过期、删除、缺失或无效，并指出本次请求使用的一个或多个 ID，适配器只删除这些映射。如果响应只说明文件状态失效而没有指出 ID，适配器会删除该次 chat 使用的全部文件映射。随后重新上传受影响的请求版本，并重试一次 chat。第二次 chat 仍报告文件失效时，适配器会按该响应清理映射并返回错误，不会发起第三次 chat。上传响应若没有完整文件对象、匹配的字节数和 `expires_at`，就不会写入索引；后续请求会再次上传，而不是信任不一致的本地状态。本地上传索引格式损坏时按空缓存处理，并由下一次成功上传替换。文件解析包括本地索引访问和远端上传，默认每张图片的时限为一分钟。默认的 stream idle 时限为五分钟，因此通常有时间执行内联回退；部署可以设置更短的 stream idle 时限，让外层时限先终止请求。每次成功解析都会刷新外层 idle watchdog。任何解析失败都会把该请求切换到内联模式；显式公共文件管理操作仍会报告自身错误。
+支持图片的路由会在自身像素与字节预算内把每个持久引用解析为确定性请求版本。`imagePixelBudget` 接受正整数或 `low`；省略时使用总计 640,000 像素，`low` 使用总计 512×512 像素，`imageMaxBytes` 默认为 1 MiB。带 alpha 的图片使用 effort 0 的 WebP，不透明图片使用 JPEG，并采用 85/75/60 质量阶梯；全部候选都超过目标时保留最小输出。每张保留图片前都有文本，注明完整附件 id 与实际请求尺寸。当前文件系统可以映射附件提供方的宿主对象时，该文本还携带只读执行世界路径与可写副本使用的扩展名。纯文本与未列出路由接收稳定附件占位符，而持久历史继续保留图片引用。
 
-同一作用域和 `variantId` 的并发解析共享一次 Files 上传，每个等待方可以单独取消。一次上传配额错误会先分页收集配置数量的最旧 `dsh-` 文件，再删除这些文件并重试一次上传。`DeepSeekFilesClient.delete`、`DeepSeekFileStore.release` 和 `releaseAll` 提供主动远端空间回收。本包记录的当前提供方限制为 Files 单次上传 128MiB、chat 单图引用 32MiB、每个 API key 最多 10,000 个文件和 25GiB；默认 1MiB 请求版本低于两个单文件上限。
+适配器通常通过 DeepSeek Files API 上传这些确切请求字节，并发送 file-id 块。文件解析失败或超时会用相同请求版本的 base64 data URL 重建整份 chat 请求；一次请求绝不混用 file id 与内联图片。缓存 id 按端点与 API key 限定作用域，在到期前刷新，根据提供方的陈旧文件错误失效，并通过带等待方局部取消的 singleflight 解析。配额失败会先删除一批配置数量的最旧 harness 文件，再重试一次上传。
 
-`contextWindow` 对每个已配置模型都可选，不会通过建议 catalog 公开。`ctx.llm.resolveModelInfo('deepseek-official', model).context` 先返回精确模型值，再对不含容量的配置项或未列出原样传递 id 返回 `defaultContextWindow`。适配器默认值为 1,000,000；因此，压力敏感插件可以获得由部署决定的容量，不会将模型 selector 视为权威。为 `deepseek-official` 注册另一个适配器会抛出 `LlmError('DUPLICATE_ADAPTER')`。
+Files 模式通过 `maxRequestFilesBytes` 与 `maxImagesPerRequest` 限制保留请求版本；内联回退有独立 base64 预算。两种模式都按配置的字节或数量量子移除最旧前缀。每张省略图片都有自己的模型可见占位符，包含显示名或附件 id，以及可用时的规范化尺寸、媒体类型与当前只读路径。分阶高水位策略避免每新增一张图片都改写旧请求前缀。
 
-`maxTokens` 是适配器为对话请求配置的输出上限，默认值为 256,000。Catalog 配置项可以自带 `maxTokens`，它对该模型胜出；不含该上限的配置项以及任何未列出原样传递 id 都解析为 profile 值，因此新增按模型的上限只改变一个模型，而非整条路由。确切模型解析会将胜出值公开为 `defaultMaxTokens`；`LlmRuntime` 会在 agent loop（智能体循环）写入 `request/header` 前，将该值填入 `GenerateOptions.maxTokens`，从而仍可根据持久记录重建协议请求。显式的请求值或 `AgentOptions.maxTokens` 值优先，并会序列化为 `max_tokens`。适配器不会根据 `contextWindow` 自动调低该请求预算；上下文或提供方输出上限较小的部署必须配置与其相容的 `maxTokens`。
+`reasoningEffort` 选择公布的默认值。当部署策略允许 thinking 时，确切模型元数据会按顺序公开 `off`、`low`、`high` 与 `max` 强度及选择指引。`low`、`high` 与 `max` 启用 thinking 并以 `reasoning_effort` 序列化，适配器自有的 `off` 则发送 `thinking.type: disabled`。不支持的取值会在网络 I/O 前以 `UNSUPPORTED_REASONING_EFFORT` 失败；`thinking: disabled` 会在插件加载时拒绝任何非 `off` 强度。`purpose: 'session-title'` 的请求会强制关闭 thinking，把有界输出留给可见标题文本。
 
-同一确切模型结果会在部署策略允许思考时，为每个原样传递模型在 `reasoning` 下公开有序且附带选择指引的 `off`、`low`、`high` 和 `max` 推理（reasoning）强度。`reasoningEffort` 选择公布的默认值，省略时回退为 `high`。`agent/request` 可以在每个会话步骤替换它；解析后的值会记录在 `request/header`。`low`、`high` 和 `max` 会启用思考，并以同名值序列化为官方顶层 `reasoning_effort`；适配器持有的 `off` 则序列化为 `thinking.type: disabled`，且省略 `reasoning_effort`。不支持的值会在网络 I/O 前以 `UNSUPPORTED_REASONING_EFFORT` 失败。
+### 动态配置
 
-`thinking: disabled` 是部署锁定：它只公布 `off`，并以 `off` 为默认值。省略 `reasoningEffort` 或将其配置为 `off` 均有效；配置 `low`、`high` 或 `max` 会使插件加载失败，直接按请求启用思考也会在网络 I/O 前失败。携带 `GenerateOptions.purpose: 'session-title'` 的请求也会强制禁用思考并省略已解析的推理强度，将有界输出保留给可见标题文本，不改变会话或压缩（compaction）默认值。
+连接事实通过可选 settings 与凭据 seam 每次操作重新读取一次。用户设置文档中的 `llm-deepseek:` 分节无需重启即可覆盖任何字段；未通过超 schema 上限的快照会保留最后有效事实并记录失败。API 密钥从提供端点、图片与 Files 策略及空闲预算的同一快照按流调用解析，因此被拒绝的设置代际不会贡献其中任何事实。图片请求在请求时解析附件服务，因此加载顺序不会冻结图片可用性。
 
-`streamIdleTimeoutMs` 会限制每次未完成提供方读取，包括初始 `fetch`，但不计入消费方在分片间花费的时间。DeepSeek SSE 注释和成功的文件解析会作为传输活动使尚未完成的读取重新计时，但绝不会成为 `StreamChunk` 值或会话日志事件。同一个稳定的 abort 信号会在整个调用期间传递给请求与 body reader；过期会停止传输并抛出 `LlmError('TIMEOUT')`，较早的调用方 abort 则抛出 `LlmError('ABORTED')`。适配器通常每次 `stream()` 调用发起一次 chat 请求，只有失效文件恢复会发起第二次。首次 chat 前的文件解析失败会发送一次内联请求。如果失效文件响应后的替换解析失败，该内联请求就是唯一允许的重试。适配器把已配置重试策略注册为提供方元数据，再由 `dsh-llm-retry` 在持久化的 agent（智能体）步骤边界单独执行该策略。
+### 提供方专用请求字段
 
-## 动态配置（settings + credentials）
+存在 `ctx.deepseekLlmApiExtensions` 时，适配器会在 `fetch` 前根据确切序列化基础请求准备已注册顶层字段。准备或字段冲突在 HTTP 前失败；2xx 响应后，适配器会在消费 SSE 前接受每项已捕获贡献。传输与非 2xx 失败不会接受它们。随产品交付的组合用它提供可选增量 `dsh_session_log` 字段和默认启用的活跃 `dsh_plugin_packages` 清单；两者都留在模型输入之外。
 
-连接事实不在加载时冻结。`resolveAdapterOptions` 是从原始配置到已校验事实的唯一显式 resolve 步骤，适配器经由一个 thunk **每操作重读一次**：base URL、catalog、请求默认值、图片和 Files 策略与 idle 预算都在下一次请求生效，进行中的流则保持其起始事实。三个可选 seam 供给该 thunk：
+### 失败与恢复
 
-- **`ctx.settings`**——插件用同一份 `Config` schema 注册 `llm-deepseek` namespace，并以其 `cordis.yml` 条目为组合 `base`，因此用户设置文档中的 `llm-deepseek:` 分节可以免重启覆盖任何字段。未挂载 settings 服务时，仅由 entry 配置驱动适配器，行为不变。存活 settings 快照若通过 schema 却违反 schema 之外的约束（重复的 catalog id、无法成立的 thinking／推理强度组合），则保留最后可用事实并记录失败；entry 配置本身仍会使插件加载失败。
-- **`ctx.credentials`**——API 密钥按每次 stream 调用解析，取自与端点*同一*份解析后的快照。配置只携带 `apiKeyEnv`，从不携带字面密钥：该引用经凭据 seam 解析，未挂载 seam 时则经受信环境层解析。由于凭据事实与连接事实同行，被 resolver 拒绝的 settings 快照既不贡献自己的端点，也不贡献自己的密钥：整个先前世代继续服务。每个解析出的密钥在使用前都会被校验格式，因此 HTTP 标头无法承载的值会以 `LlmError('INVALID_CREDENTIAL')` 被拒绝，点名失败的入口，但绝不透露密钥的任何部分，而不是以语义不明的 `fetch` `TypeError` 形式浮现。任何地方都没有密钥的请求以 `MISSING_CREDENTIAL` 失败，并点名每个配置入口，同时路由保持注册、catalog 保持可浏览——首次运行的上手流程就是「浏览模型、存入密钥、再次发起提示」，中间无需任何重启。
-- **`ctx.attachments`**——图片请求会在请求时解析该服务，因此 Cordis 加载顺序不会冻结可选图片能力。服务缺失时，图片输入以 `UNSUPPORTED_CONTENT` 失败；纯文本调用不依赖该服务。
+非 2xx 响应以稳定 code 失败：`AUTH`（401/403）、`QUOTA`、`RATE_LIMIT`、`CONTEXT_WINDOW_EXCEEDED`、`INVALID_REQUEST`、`SERVER` 以及其他情况的 `HTTP_<status>`；响应前传输失败抛出 `TRANSPORT`，调用方中止抛出 `ABORTED`，流空闲超时抛出 `TIMEOUT`。请求扩展准备、字段冲突或 2xx 后接受失败使用 `REQUEST_EXTENSION`。当提供方未指出 file id 时，规范化图片拒绝会列出所有可能附件及其持久位置。陈旧文件拒绝会使点名映射（或该次尝试使用的全部映射）失效，并允许一次替换 chat 尝试。协议违规抛出 `STREAM_CLOSED` 或 `MALFORMED_RESPONSE`；不带内容块的终止 `stop` 变成 `EMPTY_RESPONSE`，默认重试策略会重试它。任何位置都没有密钥的请求以 `MISSING_CREDENTIAL` 失败；格式错误的凭据以 `INVALID_CREDENTIAL` 失败，并点名需要修复的引用——绝不包含密钥的任何部分。
 
-唯一在注册期捕获的事实是重试策略：其解析值变化时，插件原地重新注册该路由（同一适配器实例、一个同步区段），因此 `ctx.llm.providerRetryPolicy('deepseek-official')` 始终报告当前策略。
+-----
 
-该插件还会在可配置提供方目录（`ctx.llm.listConfigurableProviders()`）中声明自己的路由：提供方为 `deepseek-official`，settings namespace 为 `llm-deepseek`，settings path 为空——整个分节就是 profile。配置界面借助该条目，把本适配器与休眠的 pi-ai 提供方一并呈现。

-存在 `ctx.deepseekLlmApiExtensions` 时，适配器会在序列化确切协议消息后、`fetch` 前准备其中已注册的顶层字段。提供方会收到同一个请求信号；即使某个提供方忽略信号，取消也会停止等待。准备失败与字段冲突会在 HTTP 前以 `REQUEST_EXTENSION` 失败。HTTP 2xx 后，适配器会先等待已准备的接受事务，再消费 SSE 正文；接受失败使用同一 code，而传输失败与非 2xx 失败不会接受字段。字段会发往解析后的 `baseURL`，包括已配置的网关。未组合该注册表的部署会发送未改变的 DeepSeek 基础请求。
+本节解释适配器背后的设计；可观察行为已在[使用本包](#use-this-package)中完整说明。
 
-随附 profile 与可运行示例会挂载 [`@deepseek-ai/dsh-session-log-deepseek`](../../session/session-log-deepseek/README.zh.md) 以提供增量 `dsh_session_log` 字段，并挂载 [`@deepseek-ai/dsh-plugin-package-inventory-deepseek`](../plugin-package-inventory-deepseek/README.zh.md) 以提供完整存活 `dsh_plugin_packages` 字段。会话日志上传默认关闭，需要设置 `session-log-deepseek.enabled: true`；插件包元数据默认开启。两个字段都对模型不可见。`llm-pi-ai` 既不导入也不调用该提供方特定注册表。
+### 设计理念
 
-## 应用归因
+插件建立在一个显式解析步骤与一条注册事实之上。`resolveAdapterOptions()` 是从原始配置到已校验连接事实的唯一路径，适配器通过 thunk 每次操作重新读取这些事实——基址、目录、请求默认值、图片与 Files 策略及空闲预算都会作用于下一个请求，而进行中的流保持其启动时的事实。注册时捕获的唯一事实是重试策略：解析值变化时，插件会在一次同步分节中原位重新注册路由，因此任何请求都观察不到空档。
 
-每个 chat 和 Files API 请求都携带 dsh-llm `attributionHeaders()` 的共享归因标头，即用于识别 harness 的必需 `User-Agent` 基线（见 [dsh-llm § 应用归因](../llm/README.zh.md#app-attribution-attributionts)）。在该适配器约定（adapter contract）下，直接 DeepSeek 请求与 OpenAI 兼容 gateway 请求都不会获得提供方特定应用归因标头；OpenRouter 应用归因暂缓到未来的显式 OpenRouter 适配器或模式。`GenerateOptions.purpose` 为 `compaction` 的请求（dsh-compaction-basic 的辅助摘要调用）还会携带 `x-deepseek-harness-compact: 1`，让宿主可以将压缩流量与会话请求分开。
+### 源码地图
 
-DeepSeek 请求身份独立于应用归因。凭据解析成功后，每个提供方请求都会通过 `x-deepseek-harness-user-id` 携带来自 [`@deepseek-ai/dsh-anonymous-user-id`](../../identity/anonymous-user-id/README.zh.md) 的稳定匿名 id；携带 `GenerateOptions.sessionId` 的请求还会通过 `x-deepseek-harness-session-id` 发送该确切值，缺少会话的直接调用则省略会话标头。两个标头都会发送至解析后的 `baseURL`（包括已配置的 gateway），且不会进入请求正文或模型可见内容。

-## 协议格式说明
+### 协议流程
 
-- 只支持流式输出（`stream_options.include_usage` 始终开启）。`usage` 可能附着在 finish 分片上，也可能作为尾随的纯 usage 分片到达；转换器会将两者都延迟到 `[DONE]`，因此 `usage` 始终位于 `finish` 之前，`finish` 之后不会出现任何内容。
-- 适配器持有的 `off` 推理强度映射为 `thinking: {type: 'disabled'}`，绝不会以 `reasoning_effort: 'off'` 通过协议发送。
-- 第一个思考模式分片携带 `reasoning_content: ""`，系统会处理它（不会产生多余 reasoning 块）。
-- **推理回传规则**：每个携带推理内容的 assistant 轮次都会将 `reasoning_content` 序列化回历史。思考模式在工具调用轮次上必需它；DeepSeek 在其他轮次上会忽略它，而将该对话重新编码转发给其他厂商的网关，要靠对回传原文取哈希来恢复该轮次上游的思考签名。
-- 支持图片的 user 消息会保留文本／图片顺序。Tool role 内容仍为字符串；连续工具结果中的图片会用 `Attached image(s) from tool result:` 汇总到随后一条 user 消息。
-- Token 计量：`cacheReadTokens` ← `prompt_cache_hit_tokens` / `prompt_tokens_details.cached_tokens`；DeepSeek 不报告 cache-write 指标。`totalTokens` 是精确的 `prompt_tokens + completion_tokens` 聚合值；提供的 `total_tokens` 若不一致，则省略该字段。
+一次 `stream()` 调用通常发一条 chat 请求：解析确定性请求图片、优先使用 Files id、准备所有已注册顶层请求扩展、向解析后的 `baseURL` 发起 fetch、在 HTTP 2xx 后接受扩展事务，并把 SSE 流翻译为 harness 协议。文件解析失败会让首条 chat 使用内联模式；提供方的陈旧文件响应允许一次替换尝试，且替换解析失败时也使用内联模式。每条 chat 与 Files 调用都在模型输入之外携带共享归因和稳定匿名用户 id，会话调用还携带 session id。推理历史会按需序列化回请求，缓存计量则把 DeepSeek 的缓存命中指标映射进 harness 用量桶。
 
-## 错误
+</details>
 
-非 2xx 响应会抛出稳定 code 的 `LlmError`：`AUTH`（401/403）、`QUOTA`（提供方详细信息标识配额、余额或点数耗尽的响应）、`RATE_LIMIT`（其他 429）、`CONTEXT_WINDOW_EXCEEDED`（提供方 code、type 或 message 标识上下文溢出的 400）、`INVALID_REQUEST`（其他 400 和 413）、`SERVER`（5xx），其他情况为 `HTTP_<status>`。其可序列化 `failure` 保留 HTTP 状态，以及有效的正 `Retry-After` 秒数／日期延迟和存在时的 `x-request-id` / `x-deepseek-request-id`。扩展准备、基础字段冲突或 2xx 后接受失败会使用 `REQUEST_EXTENSION`；扩展失败绝不会被重新标记为传输失败。如果 DeepSeek 拒绝一张已规范化图片，主错误会写明附件 ID 或显示名称、持久消息和图片位置、规范化后的媒体类型、8-bit sRGB/sRGBA 位深、尺寸和提供方消息。存在多张候选图片且提供方详细信息没有 file id 时，错误会列出全部可能图片，不会把错误归给第一张。原始响应保留为错误 `cause`，不会成为唯一的用户可见诊断。附件读取会保留稳定的附件失败 code，不会变成传输失败。响应前传输失败（DNS、连接被拒绝、TLS、proxy）会抛出命名已配置端点的 `TRANSPORT`，并将原始拒绝作为 `cause`；调用方 abort 抛出 `ABORTED`，仍以 loop 的取消信号为准。协议违例抛出 `STREAM_CLOSED`（没有 `[DONE]`）或 `MALFORMED_RESPONSE`（JSON payload 格式错误）。未知协议 `finish_reason`（例如 `content_filter`、`insufficient_system_resource`）会变为 `finish {kind: 'error', failure}` 分片；已完成流如果使用 `stop`（或缺失）finish 但没有开启内容块，就会变为 `finish {kind: 'error'}`，code 为 `EMPTY_RESPONSE`（默认策略会重试）。

 ## 模型体验
 
 ### DeepSeek 请求
 
-#### 模型看到的内容

-Generic multi-provider adapter for the harness LLM seam backed by [`@earendil-works/pi-ai`](https://www.npmjs.com/package/@earendil-works/pi-ai). One plugin instance owns a dict of provider profiles keyed by route; every request selects a profile with `GenerateOptions.provider` and resolves `GenerateOptions.model` against that route's configured catalog. A route naming an installed pi-ai provider inherits its endpoint, wire protocol, and model catalog as defaults and overrides them field by field; a route pi-ai does not ship is declared outright, so an OpenAI-compatible gateway, a self-hosted server, or a provider newer than the installed catalog is configuration rather than a code change.
+## Summary
 
-The package root exposes the Cordis plugin contract, `PiAiAdapter`, and `supportedProtocols()`; profile resolution, catalog materialization, provider construction, replay conversion, and stream conversion remain package-internal.
+`@deepseek-ai/dsh-llm-pi-ai` is the pi-ai-backed multi-provider adapter for the harness LLM service: one plugin instance owns a dictionary of provider routes, each served through [`@earendil-works/pi-ai`](https://www.npmjs.com/package/@earendil-works/pi-ai). A route naming an installed pi-ai provider inherits its endpoint, wire protocol, and model catalog as defaults; a route pi-ai does not ship is declared outright, so an OpenAI-compatible gateway or self-hosted server is configuration, not a code change. Profiles and credentials resolve per request over the optional settings and credential seams, so editing the user settings document changes the next request without a restart. A provider that ships a login can be signed into through the harness authorization seam, and the stored sign-in — an OAuth grant, or a key typed into pi-ai's own login prompt — authenticates its route and refreshes itself under the store's cross-process lock. The plugin can mount dormant with zero routes and activate them the moment a settings section supplies profiles.
 
-## Config
+## Table of Contents
 
-Configure credentials, the model catalog, and deployment-specific transport settings per provider, keyed by the provider route itself. Each profile may set a `retryPolicy`; omission uses normal mode with five retries. `apiKeyEnv` is a credential *reference* resolved per request, so no secret enters this file. Omitting it leaves the route unauthenticated, which for an installed catalog route means pi-ai's provider-native ambient discovery; a configured reference that resolves to nothing fails the request with `MISSING_CREDENTIAL` instead, because falling through would authenticate with whatever unrelated key the environment happens to hold. One credential serves every model on its route.

+## Use this package
+
+Mount this plugin when a composition routes model requests through pi-ai's provider catalogs or through gateways that pi-ai's installed catalog does not describe. The `providers` dictionary is the whole configuration surface: each key is the provider route name a request selects with `GenerateOptions.provider`.
+
+### When to choose it
+
+Choose this adapter when the same composition serves several providers, when a route needs pi-ai's catalog defaults with a few fields corrected, or when a hand-declared gateway must be reached through its own endpoint and protocol. Choose `dsh-llm-deepseek` for the direct DeepSeek route when the deployment needs no other provider. Both adapters can be mounted together because their route names do not collide; registering a route another adapter already owns fails plugin loading.
+
+### Configure provider routes
+
+Each profile may set a `retryPolicy`; omission uses normal mode with five retries. `apiKeyEnv` is a credential reference resolved per request through the harness credential seam, so no secret enters the configuration file; a reference that resolves to nothing fails the request with `MISSING_CREDENTIAL`. Omitting it leaves the route configured-but-keyless, which for an installed catalog route defers to pi-ai's provider-native ambient discovery.

-The dict shape makes duplicate routes unrepresentable, and the pre-release array shape (with per-profile `provider` fields) fails load with migration directions. `providers` may also be empty or omitted entirely: the adapter then mounts **dormant** — zero routes, no extra catalog entries — and registers routes the moment the `llm-pi-ai:` settings section supplies profiles, dropping them again when it empties. Dormant or not, the plugin declares every installed catalog provider in the configurable-provider directory (`ctx.llm.listConfigurableProviders()`, settings path `providers.<provider>`), joined with every route the current profiles declare, so configuration surfaces can offer the full catalog before any route exists and can still address a hand-declared one. Each entry carries `declared`: whether pi-ai ships nothing under that key. It follows the installed catalog, never the settings document, because narrowing a shipped provider's models stores a profile too and that route is still one pi-ai knows — only the adapter can tell the two apart, which is why the directory answers rather than leaving a surface to infer it. Which adapters exist is composition; which providers run can be entirely the user's settings document. Registration with `ctx.llm` is atomic: a collision with any provider route already owned by another adapter fails plugin loading without registering the remaining routes. Model ids are not lifecycle config; a model the route does not configure fails before any provider request with `LlmError('UNKNOWN_MODEL')`.

-## Catalog resolution
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-llm-pi-ai) is the exhaustive source for every accepted field and its JSDoc.
 
-A profile's `models` list *replaces* the route's installed catalog rather than extending it; omitting it (or leaving it empty) serves that catalog unchanged. Each entry defaults its unset fields from the installed model of the same `id`, so narrowing a catalog route to two models, correcting one capacity, or adding a model newer than the installed catalog are all one-line edits — but declaring any `models` list means every model the route should keep serving must appear in it, an entry of nothing but `id` being enough. The configurable entry fields are `id`, `name`, `contextWindow`, `maxTokens`, `reasoningEfforts`, and `compat`. Pricing and input modalities have no harness consumer and ride the installed entry or are absent.
+### Sign in to a provider
 
-`modelOverrides` reshapes individual installed-catalog models without that cost: each key is a catalog model id, each value the same fields a `models` entry takes with the id living in the key, and the rest of the catalog keeps serving untouched — "correct one model, keep the other thirty-seven" as a three-line edit. An override becomes that catalog entry's configuration, so capacities, efforts, and compat resolve through the same path with the same diagnostics and the same request-default semantics as a `models` entry. Overrides are only meaningful on a catalog route serving its catalog: one set beside a `models` list (which already replaces the catalog), on a hand-declared route (whose models are fully spelled in `models`), or naming a model the catalog does not describe is refused rather than skipped, because a silently unchanged model is a typo someone would otherwise hunt for.
+A provider pi-ai ships a login for can be signed into through the harness authorization seam: the flow offers OAuth or an interactive key prompt (a key is typed into pi-ai's own login prompt, not into the settings form), and the resulting credential is stored in the harness credential store at `llm-pi-ai/<provider id>`. The stored sign-in authenticates its route beneath any `apiKeyEnv` override and refreshes itself under the store's cross-process lock; signing out deletes the stored record. A hand-declared route key outside the record grammar — a lowercase hyphenated identifier — cannot be signed into, because a record write for it refuses with `LlmError('UNSTORABLE_PROVIDER_ID')`; such a route authenticates through `apiKeyEnv` or ambient provider settings instead.
 
-### Per-model reasoning efforts
+### Resolve the model catalog
 
-`reasoningEfforts` declares a model's selectable thinking levels: each key is a level selectors offer, its value the spelling dispatch sends on the wire, so `high: high` passes the canonical name through while `max: ultra` renames it for a gateway with its own vocabulary. Keys come from pi-ai's level set (`off`, `minimal`, `low`, `medium`, `high`, `xhigh`, `max`); a level not declared is not offered. Omitting the field keeps the installed catalog entry's capability (a hand-declared model has none and does not reason); `false` declares a non-reasoning model, which is how a profile strips reasoning from a catalog model its gateway cannot serve; an empty declaration is refused rather than guessing between those two meanings.
+A profile's `models` list replaces the route's installed catalog rather than extending it; each entry defaults its unset fields from the installed model of the same id, so narrowing a route to two models, correcting one capacity, or adding a model newer than the installed catalog are one-line edits. `modelOverrides` reshapes individual installed-catalog models without that cost — correct one model, keep the other thirty-seven — and is refused when set beside a `models` list, on a hand-declared route, or naming a model the catalog does not describe, because a silently unchanged model would be a typo someone hunts for later.
 
-The declaration translates to pi-ai's `Model.reasoning` + `thinkingLevelMap` with every level decided explicitly — undeclared levels are pinned unsupported rather than left to pi-ai's own defaulting, which is asymmetric (an absent key means "supported" for the five base levels but "unsupported" for `xhigh`/`max`) and which a profile author should not need to know. `off` is the one three-state key: left out, selectors offer no Off and an explicit Off request is refused — a request naming no effort still goes out without the parameter, so what the provider then does is its own default; declared with no value (`off:`), Off is offered and selecting it sends nothing — for the `deepseek` dialect an explicit `thinking: {type: "disabled"}` — which also covers a request naming no effort at all; declared with a value (`off: none`), that value goes on the wire as the effort parameter. There is no spelling for restoring a catalog map key to "unset": the declaration is the whole offer, so restate the catalog levels you keep.
+### Run with reasoning and wire compatibility
 
-### Wire-compatibility switches
+`reasoningEfforts` declares a model's selectable thinking levels: each key is a level selectors offer, its value the spelling dispatch sends on the wire, so `max: ultra` renames a level for a gateway with its own vocabulary. Omitting the field keeps the installed catalog entry's capability; `false` declares a non-reasoning model. `compat` switches reshape the request for endpoints pi-ai cannot recognize — which role carries the system prompt, which field caps output, how a thinking level travels — configurable per route and per model. A model neither the entry nor the installed catalog sizes takes the route's `defaultContextWindow` and `defaultMaxTokens` fallbacks.
 
-pi-ai shapes each request from the provider id and baseURL: which role carries the system prompt, which field caps output, how a thinking level travels. A private gateway's URL says nothing, and for an endpoint pi-ai does not recognize the detection answers as though it were OpenAI itself — a reasoning model's system prompt goes out as `developer`, the output cap as `max_completion_tokens`, the thinking level as a bare `reasoning_effort` — and most OpenAI-compatible gateways reject at least one of those. `compat` is therefore configurable on the route (its models' default) and per model (winning per field), resolving model → route → installed catalog entry → pi-ai's own detection; a route-level switch shadows the catalog entry's value for every model that reads it, and there is no spelling for handing a field back to the catalog short of restating its value.
+### Change configuration at runtime
 
-Each switch belongs to the protocols whose pi-ai compat type declares it, and grouping follows the compat *type* rather than the protocol name: the three Responses protocols (`openai-responses`, `azure-openai-responses`, `openai-codex-responses`) share one compat type, so a switch settable on one is settable on all three. `supportsDeveloperRole` is settable on `openai-completions` and on those three; `thinkingFormat` only on `openai-completions`; `supportsTemperature` only on `anthropic-messages`; `supportsStrictMode` also reaches `bedrock-converse-stream`. A model-level switch its protocol does not take fails resolution naming what that protocol does offer; a route-level one lands on the models that read it and skips the rest, and is refused only when no model on the route could read it at all.
+Profiles are re-read once per operation through the optional settings seam: the base and the user's `llm-pi-ai:` settings section merge per provider, so a user can add a route, override one field of a composition route, or point a route at another proxy, all effective on the next request with no restart. A section the adapter could not serve is refused where it is written — `settings.mutate` answers `settings-rejected` — and a stored section that later fails keeps the namespace's last good value. When the route set or a route's retry policy changes, the plugin re-registers atomically: a conflicting route leaves the previous routes serving.
 
-Three kinds of key are refused rather than dropped: one no protocol declares (a misspelling), one pi-ai's installed catalog owns for a named vendor (`openRouterRouting`, `zaiToolStream`, `deferredToolsMode`, `sessionAffinityFormat`, `supportsOpenAIGrammarTools`, `supportsAdditionalTools`, `supportsToolSearch`, `supportsExplicitPromptCacheMode`, `supportsToolReferences`, `vercelGatewayRouting`, `sendSessionAffinityHeaders`) — a route needing a vendor's own switch is a catalog route that should be named as such — and one written with no value at all (`supportsDeveloperRole:`), which schemastery passes through as null and which would otherwise replace the installed catalog's value with nothing. The offered set is pinned to pi-ai's four compat types by drift gates, the protocols carrying them are derived from `Model.compat` itself, and each field's type is derived from upstream rather than restated, so an upgrade that adds a field, gives a further protocol a compat type, or widens a value union fails the build until someone classifies it.
+### Discover models from endpoints
 
-A model neither the entry nor the installed catalog sizes takes the route's `defaultContextWindow` (262,144) and `defaultMaxTokens` (32,768), so a listing that discloses nothing but ids still yields a serviceable route. Both fallbacks are guesses by construction, which is why they are route fields a deployment whose gateway serves smaller models corrects once rather than constants buried in the adapter; the fallback sizes the model and never becomes a per-request cap.
+The plugin answers "which models can this provider serve?" for a route a configuration surface is editing or drafting. A route the installed catalog ships is answered from that catalog with no network call; only a route the catalog does not describe is interrogated over the wire (`openai-completions` and `openai-responses` shapes). The reply is candidate metadata a surface may offer for adoption — nothing is stored, and `settings.yaml` remains the only thing that decides what a route serves.
 
-Request modalities resolve entry `input` → installed catalog entry → route `defaultInput` (default `[text]`), the same order and the same fallback role the capacities above use. So a catalog model keeps the modalities the catalog records for it, and a narrower route default never strips them; a gateway whose *undescribed* models all take images declares `[text, image]` once at the route instead of on every entry. An entry's empty list means the same as an absent one — it describes a model accepting nothing, so it states no answer and resolution continues past it, which is what keeps a catalog model's own modalities when a `models` entry names it without declaring any. The route's may not be empty, since nothing sits below it to answer instead.
+### Failures and recovery
 
-`[text]` is the absence of a declaration rather than a guess at the endpoint, which is why the fallback here is conservative where the capacity fallbacks are merely plausible. Nothing interrogates a gateway for what it accepts, and the two wrong answers do not cost the same: the harness refuses an image before it is attached when a model's modalities omit one, so under-claiming costs a refusal naming the model, while over-claiming admits an image the provider then rejects mid-turn — after the message is durable, which leaves the session repeating a request that cannot succeed.
+A route pi-ai does not ship needs `api`, `baseURL`, and a non-empty `models` list; an unserviceable profile is refused where it is written, naming the route and model. Failures carry stable codes: a credential that cannot be used fails with `INVALID_CREDENTIAL` naming the route and reference, a route whose `apiKeyEnv` reference resolves to nothing fails with `MISSING_CREDENTIAL`, an unconfigured model fails with `UNKNOWN_MODEL`, and terminal provider failures distinguish `QUOTA` from transient `RATE_LIMIT`. `GenerateOptions.stop` is rejected with `UNSUPPORTED_OPTION` because pi-ai's common streaming UI cannot guarantee it across providers.
 
-Resolution still fails loud, naming the offending route and model, when a route cannot be served at all: a route the catalog does not ship needs `api`, `baseURL`, and a non-empty `models` list of uniquely-identified models. That resolution runs inside the section schema, so an unserviceable profile is refused **where it is written** — `settings.mutate` answers `settings-rejected` naming the route and model — rather than being stored and then quietly disabling every route in the namespace. The settings seam keeps a namespace's last good value for an already-stored section that fails, so this cannot strand a deployment. `api` accepts the protocols in `supportedProtocols()` and is only needed when the catalog cannot supply one: a model absent from the catalog inherits the protocol its shipped siblings agree on, so adding a model to a single-protocol catalog route restates nothing.
+-----
 
-`baseURL` sets the endpoint of every model on the route, so private proxies such as `https://proxy.example.com:8443` remain supported; a catalog route that omits it keeps each catalog model's own endpoint. Naming `api` on a catalog route repoints the whole route at that protocol, which is how a deployment moves a provider between, say, Responses and Chat Completions.
+<a id="understand-the-implementation"></a>
+## Understand the implementation
 
-`supportedProtocols()` is deliberately narrower than pi-ai's full streaming API set: it holds only the protocols a profile can *completely* describe with a key, an endpoint, and headers. Bedrock signs with SigV4 over AWS credentials and a region, Vertex needs a project, a location, and application-default credentials, Azure needs provider environment plus an api-version, and Codex authenticates through OAuth — offering those would hand back a route that cannot authenticate. Catalog routes still reach them through their own provider; only an explicit override is refused.

-## Dynamic configuration (settings + credentials)
+This section explains the design behind the adapter; the observable behavior is fully covered in [Use this package](#use-this-package).
 
-The adapter reads its profiles through a thunk **once per operation** instead of freezing them at construction. The plugin registers the `llm-pi-ai` namespace on the optional `ctx.settings` seam with this same `Config` schema and its `cordis.yml` entry as the composition `base`, and because `providers` is a dict, the base and the user's `llm-pi-ai:` settings section merge **per provider**: a user can add a route, override one field of a composition route, or point a route at another proxy, all effective on the next request with no restart. Without a mounted settings service the entry config alone drives the adapter, unchanged.
+### Design philosophy
 
-Credentials resolve per stream call through `apiKeyEnv` and the optional `ctx.credentials` seam; without that seam, the adapter reads exactly the referenced environment variable. A profile naming no credential at all — and only that case — defers to pi-ai's ambient discovery. Every resolved key is trimmed and format-checked before use, so a value no HTTP header can carry is refused instead of surfacing as an opaque `fetch` `TypeError`; the refusal throws `LlmError('INVALID_CREDENTIAL')` naming the failing route and credential reference but never any part of the key. The route set and each route's captured retry policy are the registration-level facts: when either changes, the plugin replaces its registration atomically (same adapter instance, candidate set validated first), so a route another adapter already owns leaves the previous routes serving and reverting to a working configuration re-applies. Provider key order never counts as a change. A section this adapter could not serve is refused where it is written — the registered `validate` resolves the whole profile set, so `ctx.settings.mutate` rejects with the resolver's own error (the wire surface reports it as `settings-rejected`) and nothing is stored. A stored section that becomes unserviceable some other way — an external edit of `settings.yaml` — keeps the namespace's last good value at the settings seam and warns. The entry config itself still fails plugin load, and a route the llm registry refuses (one another adapter family already owns) is logged while the previously registered routes keep serving.
+The adapter is built on immutable snapshots and per-operation resolution. Each operation captures a whole snapshot — the profiles plus a `createModels()` collection holding the `Provider` each route built — before its first `await`, and a configuration change builds a new collection rather than mutating the one in use, so a request that started under one configuration never finishes under another. A route's own credential reference resolves through the harness seam and rides as the request's `apiKey` option, which pi-ai treats as the highest-priority auth override — that is what keeps the fail-loud reference semantics. Everything that override does not cover reaches pi-ai through the collection's own auth: the credential store holds the records a login wrote and a refresh rotates (addressed as `llm-pi-ai/<provider id>`), and the auth context answers the ambient questions a provider asks while resolving. Both are stable across snapshots, so a configuration change rebuilds the collection without forgetting who is signed in.
 
-The adapter exposes each configured route's models through `ctx.llm.listModels(provider)`. This is provider-neutral selector metadata read from the same pi-ai `Models` collection the request path uses, so discovery does not create a second model registry. `ctx.llm.resolveModelInfo(provider, model)` performs that exact descriptor lookup once and returns its identity, context window, configured output cap, and selectable thinking levels, keeping authoritative metadata on the route-owning adapter rather than its consumers. A model's **configured** `maxTokens` becomes the seam's `defaultMaxTokens`, so a request that names no output cap carries the one the deployment chose; a value inherited from the installed catalog is the model's output *capability* and never becomes a request default on its own.
+### Source map
 
-A model that carries reasoning metadata — from the installed catalog or from its entry's `reasoningEfforts` — exposes pi-ai's ordered `getSupportedThinkingLevels(model)` result without filtering or normalization, including `off` and the model-specific availability of `xhigh` or `max`. The Harness exposes each canonical pi-ai level as an opaque ID; provider/model wire spellings remain inside pi-ai's `thinkingLevelMap`.

-A model **without** that metadata — a hand-declared one whose entry declares no `reasoningEfforts`, and a catalog model pi-ai marks as non-reasoning — exposes no `reasoning` at all. pi-ai reports such a model as supporting the single level `off`, but `off` is translated to *omitting* the reasoning option, which is byte-for-byte the request that naming no effort already produces: selecting it could not disable anything, so a provider whose own default is to think would keep thinking with `off` shown as selected. Reporting the capability as unavailable leaves a surface offering the provider's default and nothing that misrepresents it. The profile `reasoning` value, including `off`, is the deployment default when configured; omitting it preserves the provider default. Per-request `GenerateOptions.reasoningEffort` takes precedence, and a level absent from the exact model capability fails the REQUEST with `UNSUPPORTED_REASONING_EFFORT` before network I/O instead of being clamped. Describing a model never fails that way: the models under one provider disagree about which levels they accept, so `resolveModel` reports a profile level the exact model cannot take as no default at all rather than throwing. A throw there would take the whole provider out of every model catalog built over it — one mis-set profile field hiding even the models that do support the level — so a bad configuration surfaces where it is acted on, not where it is described. pi-ai's common stream options represent `off` by omitting `reasoning`.
+### Registration and directory
 
-Supported profile fields are `apiKeyEnv`, `displayName`, `api`, `baseURL`, `models`, `modelOverrides`, `compat`, `defaultContextWindow`, `defaultMaxTokens`, `defaultInput`, `headers`, `reasoning`, `thinkingBudgets`, `cacheRetention`, `transport`, `timeoutMs`, `websocketConnectTimeoutMs`, `streamIdleTimeoutMs`, `maxRequestImageBytes`, `requestImagePixelBudget`, `requestImageMaxBytes`, and `retryPolicy`. Each resolved profile retry policy is captured with that provider route; omission uses the shared bounded normal default of five retries. The stream-idle interval is a positive finite Node timer delay, defaults to five minutes, and covers only an outstanding provider read, not consumer think time. Every image route derives a deterministic request version from the provider-independent normalized attachment under `requestImagePixelBudget` (default 2048 by 2048 total pixels) and `requestImageMaxBytes` (default 1MiB raw bytes). Before reading attachments, `maxRequestImageBytes` applies to conservative request-version upper bounds and replaces the oldest over-budget images with per-image text; exact base64 lengths are checked again after retained versions are generated. The 20MiB default can retain fifteen 1MiB-target versions after base64 expansion while leaving request-body headroom. The same version feeds inline base64. Its descriptor exposes the attachment id and actual request-image dimensions, plus a normalized-object path only when the attachment provider exposes a host object and the current filesystem maps it into the tool execution world. The path is resolved separately from the request version and its `variantId`. Harness app attribution wins a conflicting configured header name.
+The plugin declares every installed catalog provider it can authenticate in the configurable-provider directory, joined with every route the current profiles declare, so configuration surfaces can offer the full catalog before any route exists. Each entry carries `declared` — whether pi-ai ships nothing under that key — because only the adapter can distinguish a hand-declared route from a narrowed catalog route. Route registration is atomic: a candidate set that collides with another adapter leaves the previous routes serving. A bare mount with zero routes is the dormant posture: nothing registers until a settings section supplies profiles, and routes drop when it empties.
 
-The adapter forces pi-ai's SDK `maxRetries` to zero so one `stream()` call makes one provider request. The removed profile fields `maxRetries` and `maxRetryDelayMs` fail load instead of silently multiplying or hiding the separately composed agent-level retry budget. Idle expiry aborts the SDK's stable request signal and surfaces `TIMEOUT`; an earlier caller abort remains `ABORTED`.
+### Replay and vocabulary
 
-## Endpoint interrogation
+Successful assistant responses store a versioned, lossless-JSON replay state beside the provider and model that produced them — response-level facts plus one per-block entry per streamed block. At request time, `LlmRuntime` passes replay state only when the same adapter instance owns both routes; the adapter validates it and restores native response ids and provider signatures, degrading an unusable state to provider-neutral content instead of failing the request. pi-ai tool-call arguments are parsed objects, so the adapter parses input and re-stringifies output to the harness raw-JSON convention; pi-ai in-stream error events map to terminal `finish` chunks.
 
-The plugin offers `ctx.llm.registerModelDiscovery('llm-pi-ai', …)`, which answers "which models can this provider serve?" for a route a configuration surface is editing or drafting. It is deliberately *not* a catalog refresh: nothing is stored, and the reply is candidates the surface offers for adoption. `settings.yaml` remains the only thing that decides what a route serves.
+</details>
 
-A request naming a route the **installed catalog ships is answered from that catalog**, with no network call: pi-ai's registry is the authoritative list for its own providers, and it carries the context windows and output caps a listing endpoint would not disclose. Such a route needs no `baseURL` at all. Only a route the catalog does not describe — a gateway, a self-hosted server — is interrogated over the wire, and one that names no endpoint is told to set one or enter its models by hand.
+-----
 
-A draft carries the credential the user typed, if any; a route that already stored one shows a configuration surface only a redacted descriptor, so the interrogation resolves that route's `apiKeyEnv` rather than going out unauthenticated and reporting the endpoint's 401 as a wrong key. A typed key wins, being the one under test. Resolution happens only on the path that reaches the network, so a catalog route answers without touching credentials at all. A supplied or stored probe key is trimmed and format-checked the same way, so a value no HTTP header can carry is refused immediately as `LlmError('INVALID_CREDENTIAL')` instead of reaching `fetch`, where it would surface as an opaque `ByteString` failure indistinguishable from an unreachable endpoint.
+<a id="further-exploration"></a>
+## Further Exploration
 
-Interrogation reads `openai-completions` and `openai-responses`, whose `GET /models` shape with bearer auth is the one a gateway, a self-hosted server, and the official endpoints all agree on. Azure is excluded despite its OpenAI lineage — it authenticates with an `api-key` header and requires an `api-version` query — and Codex uses OAuth; every other protocol answers `DISCOVERY_UNSUPPORTED` so the surface falls back to hand-entry instead of an authentication failure being reported as a provider with no models. The `baseURL` is treated as a prefix rather than a URL to resolve against, so a deployment path such as `https://gateway.example/openai/v1` keeps its segments.
+Read these pages when the package-level contract is not enough. They move from the service contract to the twin adapter and the shared types.
 
-Most listings disclose an id and nothing else; `context_window`/`context_length` and `max_output_tokens`/`max_tokens` are read when a gateway supplies them, entries without a usable id are skipped rather than failing the whole listing, and everything else the adopting surface still owes. The reply is read under a four-megabyte ceiling enforced on the bytes actually received — the endpoint is a URL the user typed, so a declared length is checked first but never trusted as the bound. An unreachable endpoint, a refused credential, a non-JSON body, and a body with no `data` array all fail with `DISCOVERY_FAILED` and a message naming the endpoint and, for a 401 or 403 alone, the credential. Cancellation during the body read surfaces as `ABORTED`, like a cancellation before the request went out.

-## Provider/model routing and replay
-
-Each resolution produces one **immutable** snapshot — the profiles plus a `createModels()` collection holding the `Provider` each route built — and every operation captures a whole snapshot before its first `await`. A configuration change builds a *new* collection rather than mutating the one in use: `Models.streamSimple()` resolves its provider lazily, when the stream is first consumed, which is after the credential await, so a mutated collection would let a request that started under one configuration finish under another or fail on a provider that no longer exists. This is what makes the seam's per-step call freeze (`llm.prepareCall()`) hold end to end — switching models mid-reply takes effect on the next step, never inside the one in flight. Requests reach their provider through `Models.streamSimple()`. A catalog route that keeps its catalog protocol **reuses** the installed provider with its model list replaced, because that provider owns API implementations this package cannot reconstruct — Bedrock loads its Smithy module through a separate entry point — so rebuilding it from parts would silently narrow which providers work. Every other route is built by `createProvider()` over the protocol table behind `supportedProtocols()`, whose entries are the same factories pi-ai's own provider factories use.
-
-A route's `apiKeyEnv` key still resolves through the harness seam before the request reaches pi-ai and rides as the request's `apiKey` option, which pi-ai treats as the highest-priority auth override — the fail-loud reference semantics stay the harness's. Beneath that override the collection carries this plugin's credential store and ambient auth context: a stored sign-in (an OAuth grant, or a key typed into pi-ai's own login prompt) authenticates its route through them and refreshes itself under the store's cross-process lock. The store addresses records as `llm-pi-ai/<provider id>`, and a hand-declared route key outside that record grammar (uppercase, dots, underscores) reads as holding nothing stored rather than as an addressing error; such a route cannot be signed into — a record write for it refuses with `LlmError('UNSTORABLE_PROVIDER_ID')` — and authenticates through `apiKeyEnv` or ambient provider settings. A route naming no credential at all resolves as configured-but-keyless and leaves the requirement to the protocol, which is where it actually lives.
-
-The selected model descriptor supplies the protocol implementation. This includes native API differences such as OpenAI models whose descriptor uses the Responses API rather than Chat Completions; the harness adapter does not hardcode endpoint selection by model name.
-
-Successful assistant responses store a versioned, lossless-JSON replay state beside the provider and model that produced them, as a `ReplayEnvelope`: a response-level half (kind, version, API, route, response ids, native stop reason) plus one per-block entry per streamed block carrying that block's signatures. The per-block alignment is what `BlockAssembler` prunes when assembly drops a block (a `max-tokens` tool call), so the stored entries always describe the stored content — the retained blocks keep their signatures. At request time, `LlmRuntime` passes replay state only when the historical provider route and target provider route are currently owned by this same `PiAiAdapter` instance. The adapter validates the state and restores pi-ai response ids and provider signatures even when the target provider or model changes; pi-ai then decides which metadata its target API can reuse. History without replay state is translated as foreign provider-neutral content and never impersonates a native pi-ai response.
-
-Durable content is the authoritative record; replay state only restores native fidelity. A stored state this build cannot use — another adapter's kind, another version (including the flat pre-envelope form older logs carry), malformed metadata, provider/model mismatches between the message and replay state, or content/block mismatches — degrades that one assistant message to the same foreign provider-neutral conversion instead of failing the request, and the plugin logs the `INVALID_REPLAY_STATE` diagnostic through its `onReplayDegrade` hook.
-
-## Vocabulary differences
-
-- pi-ai tool-call arguments are parsed objects; the harness stores raw JSON strings. The adapter parses input and re-stringifies output.
-- pi-ai reports failures as in-stream error events; these map to `finish {kind:'error'|'aborted', failure}` chunks. Provider-specific error text distinguishes terminal `QUOTA` from transient `RATE_LIMIT`, while text and usage signals evaluated against the resolved model's context window normalize overflow to `CONTEXT_WINDOW_EXCEEDED`. A terminal `stop` whose message carries no content blocks maps to a `finish {kind:'error'}` with code `EMPTY_RESPONSE` (retried by default policy) instead of a successful empty message.
-- pi-ai folds reasoning tokens into output usage; there is no separate reasoning count to map. Its exact `totalTokens` value is preserved unchanged.
-- pi-ai's `off` thinking level crosses the Harness capability seam unchanged and becomes an omitted pi-ai common `reasoning` option at dispatch.
-- `GenerateOptions.stop` is rejected with `UNSUPPORTED_OPTION` because pi-ai's common streaming UI cannot guarantee it across providers.

-## App attribution
-
-Every request carries the shared attribution header from dsh-llm's `attributionHeaders()`, merged through pi-ai's `headers` stream option. Provider-specific app-attribution headers are not synthesized. See [dsh-llm § App attribution](../llm/README.md#app-attribution-attributionts).
-
-## Dependency weight
-
-pi-ai installs several provider SDKs and lazy-loads the one selected by the catalog model. The dependency weight is isolated to this opt-in adapter package.

 ### Provider request through pi-ai
 
 #### What the model sees
 
-The selected catalog model receives `GenerateOptions.system`, history, tools, and sampling fields supported by pi-ai's common streaming API. Each retained image is preceded by text naming its complete attachment id and actual request dimensions. The text includes a normalized-object path when the current execution filesystem maps the attachment provider's host object, marks that path read-only, and warns that normalization or request projection may have resized or re-encoded the upload. When accumulated base64 image payload exceeds the route's `maxRequestImageBytes`, each offloaded image keeps its own identity and access currently resolved for that request in replacement text. Offloaded normalized attachments are not read or transformed. Provider-native replay metadata is restored only when the adapter validates it for the historical content.

 ## Known Limitations and Deferred Work
 
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define where the adapter stops and future work begins. They are current package constraints, not a general pi-ai comparison or a task backlog.
+
 - **`maxRequestImageBytes` counts base64 image payload only** — text, tools, descriptors, and JSON structure ride outside the bound, so it must sit below the gateway's request-body cap with headroom. Offload is a deterministic request projection and is not recorded as a session event.
 - **A sign-in lives only in the process that started it** — an authorization attempt is not durable, so reloading the page mid-login abandons it and the human starts over. Signing out is `deleteRecord` on the stored record, which forgets it locally without telling the issuer.
 - **Provider-native discovery answers through this plugin's ambient context** — a route naming no credential defers to the catalog provider's own resolution, which asks for environment values (`AZURE_OPENAI_API_KEY`, `AWS_PROFILE`, and each provider's own set) and for local credential files. Both questions are answered here: the credential seam is consulted before the process environment, and file existence is checked against the host process's filesystem with `~` expanded. What it cannot do is *read* a credential file's contents — a provider that parses `~/.aws/credentials` itself does so directly, outside the seam.
-- **Settings can add or override routes, not remove composition routes** — the user layer merges over the composition `base`, so deleting a `cordis.yml`-provided provider is a composition change; `replace` on the namespace only resets the user layer.
-- **The layered merge has no delete for dict keys** — the settings seam merges the composition `base` and the user layer per key, recursively, so a `reasoningEfforts` level, `modelOverrides` entry, or `compat` field the base declares cannot be removed by the user layer, only overridden — and for `reasoningEfforts` absence *is* the meaning ("not offered"), so a base-declared level stays offered. This only triggers when a `cordis.yml` entry config declares per-model reasoning fields for the same model the user layer edits; the supported posture is to leave those to the settings document (the shipped composition mounts the adapter dormant), and a `models` list is an array replacing wholesale, which is the in-band escape.
-- **`headers` can carry a credential the redactor never sees** — the profile's `headers` dict is plain strings, so `Authorization` or `api-key` set there is returned verbatim by a redacted `describe()` and rendered by any configuration UI. Store credentials as `apiKeyEnv` references; making the dict write-only is deferred with the rest of the [wire-boundary work](../llm/README.md#known-limitations-and-deferred-work).
-- **A route's catalog never refreshes itself** — the catalog is whatever `settings.yaml` says, so a model list is only as current as its last edit. Nothing here queries a provider for the models it serves; a route gains a model when someone writes one.
-- **One wire protocol per route** — `api` applies to the whole route, so a mixed-protocol catalog route (an OpenAI-style catalog spanning Responses and Chat Completions) cannot host a model of the other protocol, and adding a model such a route does not describe requires naming `api` and moving every model onto it. Splitting the provider across two route keys is the workaround.
-- **A modality declaration is not verified** — nothing interrogates an endpoint for what it accepts, so a model declaring `image` its gateway does not serve is refused by the provider after prompt admission. The durable image remains in history and the same misdeclared model can fail again. Switching to a text-only model remains possible because the shared LLM runtime projects image references into stable text for that exact request.
-- **An unauthenticated route depends on its protocol** — naming no credential resolves the route as configured-but-keyless, but pi-ai's OpenAI-compatible implementation still requires an API key or an `Authorization` header, so a keyless local server needs a placeholder credential referenced by `apiKeyEnv` or an `Authorization` entry in `headers`.
-- **`GenerateOptions.stop` is unsupported** — pi-ai's common stream options cannot guarantee stop-sequence behavior across providers, so the adapter rejects the field.
+- **Settings can add or override routes, not remove composition routes** — the user layer merges over the composition base, so deleting a `cordis.yml`-provided provider is a composition change.

-- **Provider HTTP status is unavailable** — pi-ai error events do not expose a stable HTTP status across providers; failures expose only stable harness error codes.

+- The offered protocol set is deliberately narrower than pi-ai's full API set: Bedrock, Vertex, Azure, and Codex authenticate through flows a profile cannot completely describe with a key, an endpoint, and headers; catalog routes still reach them through their own provider, and only an explicit override is refused.

 [English](README.md) | 中文
 
-基于 [`@earendil-works/pi-ai`](https://www.npmjs.com/package/@earendil-works/pi-ai) 的 harness LLM（大语言模型）seam 通用多提供方适配器。一个插件实例拥有一份以路由为键的提供方 profile 字典；每个请求使用 `GenerateOptions.provider` 选择 profile，并针对该路由已配置的 catalog 解析 `GenerateOptions.model`。点名了已安装 pi-ai 提供方的路由会继承其端点、协议格式（wire format）与模型 catalog 作为默认值，并逐字段覆盖；pi-ai 未提供的路由则整体声明出来，因此接入 OpenAI 兼容网关、自建服务，或比已安装 catalog 更新的提供方，都属于配置而非改代码。
+## 概述
 
-包根入口导出 Cordis 插件约定、`PiAiAdapter` 与 `supportedProtocols()`；profile 解析、catalog 物化、提供方构造、回放转换和流转换保留在包内部。
+`@deepseek-ai/dsh-llm-pi-ai` 是 harness LLM 服务基于 pi-ai 的多提供方适配器：一个插件实例拥有一份提供方路由字典，每条路由都通过 [`@earendil-works/pi-ai`](https://www.npmjs.com/package/@earendil-works/pi-ai) 服务。点名已安装 pi-ai 提供方的路由会继承其端点、协议格式与模型目录作为默认值；pi-ai 不提供的路由可以直接声明，因此 OpenAI 兼容网关或自托管服务器只是配置，而非代码变更。profile 与凭据通过可选 settings 与凭据 seam 按请求解析，因此编辑用户设置文档即可改变下一个请求，无需重启。提供登录的提供方可以通过 harness 授权 seam 登录，存储的登录——OAuth grant，或在 pi-ai 自己的登录提示里键入的密钥——为其路由完成认证，并在存储的跨进程锁下自行刷新。插件可以零路由休眠挂载，一旦 settings 分节提供 profile 便立即激活它们。
 
-## 配置
+## 目录
 
-按提供方配置凭据、模型 catalog 与部署特定传输设置，并以提供方路由本身为键。每个 profile 都可以设置 `retryPolicy`；省略时使用 normal 模式并重试五次。`apiKeyEnv` 是按请求解析的凭据*引用*，因此机密不进入该文件。省略它会让该路由处于未认证状态；对已安装 catalog 路由而言，这意味着交给 pi-ai 的提供方原生环境发现。已配置却解析不出任何值的引用则相反，会让请求以 `MISSING_CREDENTIAL` 失败，因为放行下去就会用环境里恰好持有的某个无关密钥完成认证。一条凭据服务该路由下的全部模型。

+## 使用本包
+
+当组合需要通过 pi-ai 的提供方目录、或通过 pi-ai 已安装目录未描述的网关路由模型请求时挂载本插件。`providers` 字典就是整个配置面：每个键都是请求用 `GenerateOptions.provider` 选择的提供方路由名。
+
+### 何时选择
+
+当同一组合服务多个提供方、某条路由需要 pi-ai 目录默认值并修正少数字段、或必须通过自有端点与协议到达手工声明网关时，选择本适配器。当部署不需要其他提供方时，选择 `dsh-llm-deepseek` 直连 DeepSeek 路由。两个适配器可以同时挂载，因为它们的路由名不冲突；注册其他适配器已拥有的路由会导致插件加载失败。
+
+### 配置提供方路由
+
+每个 profile 都可以设置 `retryPolicy`；省略时使用 normal mode、最多重试五次。`apiKeyEnv` 是按请求经 harness 凭据 seam 解析的凭据引用，因此配置文件绝不包含密钥；解析为空的引用会让请求以 `MISSING_CREDENTIAL` 失败。省略它会让路由保持已配置但无密钥（configured-but-keyless）状态，对已安装目录路由而言即交由 pi-ai 提供方原生的环境发现。

-字典形状使重复路由无法表示，发布前的数组形状（每个 profile 携带 `provider` 字段）会加载失败并给出迁移指引。`providers` 也可以为空或整体省略：适配器将以**休眠**姿态挂载——零路由、模型选择器不多一条——一旦 `llm-pi-ai:` settings 分节提供了 profile 就即时注册路由，分节清空时随之撤销。无论是否休眠，插件都会在可配置提供方目录（`ctx.llm.listConfigurableProviders()`，settings 路径 `providers.<provider>`）中声明每个已安装 catalog 提供方，并与当前 profile 声明的每条路由取并集，因此配置界面既能在任何路由存在之前就提供完整 catalog，也能寻址一条手工声明的路由。每个条目都带上 `declared`：pi-ai 在这个键下是否什么都没有。它跟随已安装 catalog 而非设置文档，因为收窄一个内置提供方的模型同样会存下 profile，而那条路由仍然是 pi-ai 认识的——只有适配器分得清两者，所以由目录直接给出答案，而不是留给界面去猜。哪些适配器存在归组合面；哪些提供方在运行可以完全交给用户的设置文档。向 `ctx.llm` 注册具有原子性：如果与另一适配器已拥有的任何提供方路由冲突，插件会加载失败，不注册剩余路由。模型 id 不是生命周期配置；路由未配置的模型会在发起任何提供方请求前以 `LlmError('UNKNOWN_MODEL')` 失败。

-## Catalog 解析
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-llm-pi-ai)是每个受支持字段及其 JSDoc 的穷尽式真源。
 
-profile 的 `models` 列表是*替换*该路由已安装 catalog，而不是扩充它；省略它（或留空）则原样服务该 catalog。每个条目都会从同 `id` 的已安装模型继承自身未设置的字段，因此把 catalog 路由收窄到两个模型、更正某个容量，或加入一个比已安装 catalog 更新的模型，都是一行编辑——但一旦声明了 `models` 列表，该路由要继续服务的每个模型就都必须出现在其中，条目哪怕只写一个 `id` 也足够。可配置的条目字段是 `id`、`name`、`contextWindow`、`maxTokens`、`reasoningEfforts` 与 `compat`。定价与输入模态没有 harness 消费方，因此沿用已安装条目或直接缺席。
+### 登录提供方
 
-`modelOverrides` 无需这份代价就能就地重塑单个已安装 catalog 模型：每个键是一个 catalog 模型 id，每个值可写 `models` 条目接受的同一批字段，只是 id 落在键上，而 catalog 的其余部分原样继续服务——「改一个模型、其余三十七个原样保留」只是一次三行编辑。一条覆盖会成为该 catalog 条目的配置，因此容量、档位与 compat 沿与 `models` 条目相同的路径解析，携带相同的诊断与相同的请求默认值语义。覆盖只在正服务自身 catalog 的 catalog 路由上才有意义：与 `models` 列表并存的一份（该列表本就替换了 catalog）、落在手工声明路由上的一份（其模型已在 `models` 中完整写出），或点名了 catalog 未描述模型的一份，都会被拒绝而非跳过，因为一个静默保持原样的模型，就是一个否则要有人费力追查的笔误。
+pi-ai 提供登录的提供方可以通过 harness 授权 seam 登录：流程提供 OAuth 或交互式密钥提示（密钥键入 pi-ai 自己的登录提示，而非设置表单），得到的凭据存储在 harness 凭据存储的 `llm-pi-ai/<provider id>` 记录中。存储的登录在其路由的 `apiKeyEnv` 覆盖之下完成认证，并在存储的跨进程锁下自行刷新；退出登录即删除存储记录。落在记录文法之外——小写连字符标识符——的手工声明路由键无法登录，因为对它的记录写入会以 `LlmError('UNSTORABLE_PROVIDER_ID')` 拒绝；这类路由改用 `apiKeyEnv` 或提供方 ambient 设置认证。
 
-### 按模型的推理（reasoning）档位
+### 解析模型目录
 
-`reasoningEfforts` 声明模型可选的思考级别：每个键是选择器提供的一个档位，其值是分派在协议中发送的拼写，因此 `high: high` 原样透传规范名称，而 `max: ultra` 则为使用自有词汇的网关改名。键取自 pi-ai 的档位集合（`off`、`minimal`、`low`、`medium`、`high`、`xhigh`、`max`）；未声明的档位不会被提供。省略该字段会保留已安装 catalog 条目的能力（手工声明的模型没有这份能力，也不推理）；`false` 声明一个不具备推理能力的模型，profile 正是以此从其网关无法服务的 catalog 模型上剥除推理；空声明会被拒绝，而不是在这两种含义之间去猜。
+profile 的 `models` 列表会替换而非扩展路由的已安装目录；每个条目从同 id 已安装模型取未设置字段的默认值，因此把路由收窄到两个模型、修正一个容量或添加比已安装目录更新的模型都是一行编辑。`modelOverrides` 无需该代价即可重塑个别已安装目录模型——修正一个模型，保留其余三十七个——当它与 `models` 列表并存、位于手工声明路由上、或点名目录未描述的模型时会被拒绝，因为静默不变的模型会成为别人日后寻找的拼写错误。
 
-该声明会转换为 pi-ai 的 `Model.reasoning` + `thinkingLevelMap`，其中每个档位都被显式决定——未声明的档位一律固定为不支持，而不是留给 pi-ai 自己的默认规则：那套规则并不对称（键缺席对五个基础档位意味着「支持」，对 `xhigh`/`max` 却意味着「不支持」），也本不该要求 profile 作者了解。`off` 是唯一的三态键：不写它，选择器不提供 Off，显式请求 Off 会被拒绝——不点名任何档位的请求仍会在不带该参数的情况下发出，提供方随后做什么是它自己的默认行为；声明而不给值（`off:`），则会提供 Off，选中它时什么也不发送——对 `deepseek` 方言则是一个显式的 `thinking: {type: "disabled"}`——这同时覆盖完全不点名任何档位的请求；声明并给值（`off: none`），该值就会作为档位参数在协议中发送。没有任何写法能把 catalog 映射中的键恢复为「未设置」：这份声明就是对外提供的全部，因此把你要保留的 catalog 档位重述出来。
+### 带推理与协议兼容运行
 
-### 协议兼容开关
+`reasoningEfforts` 声明模型可选择的 thinking 等级：每个键都是选择器提供的等级，其值是该等级过线的拼写，因此 `max: ultra` 可以为拥有自有词汇的网关重命名等级。省略该字段时保留已安装目录条目的能力；`false` 声明非推理模型。对于 pi-ai 无法识别的端点，`compat` 开关重塑请求——哪个角色携带系统提示词、哪个字段限制输出、thinking 等级如何传递——可逐路由、逐模型配置。条目与已安装目录都没有尺寸的模型，会采用路由的 `defaultContextWindow` 与 `defaultMaxTokens` 回退值。
 
-pi-ai 依据提供方 id 与 baseURL 决定每个请求的形状：系统提示词由哪个角色承载、输出上限写在哪个字段、思考级别如何传输。私有网关的 URL 什么也说明不了，而对于 pi-ai 无法识别的端点，其检测会当作 OpenAI 本身来回答——推理模型的系统提示词以 `developer` 发出、输出上限写作 `max_completion_tokens`、思考级别只发一个裸的 `reasoning_effort`——而多数 OpenAI 兼容网关至少会拒绝其中之一。因此 `compat` 既可配置在路由上（作为其模型的默认值），也可按模型配置（逐字段胜出），解析顺序为模型 → 路由 → 已安装 catalog 条目 → pi-ai 自身的检测；路由级开关会为每个读取它的模型遮蔽 catalog 条目的值，而且除了重述其值，没有任何写法能把某个字段交还给 catalog。
+### 运行时更改配置
 
-每个开关归属于其 pi-ai compat 类型声明了它的那些协议，且归组依据是 compat **类型**而非协议名：三个 Responses 协议（`openai-responses`、`azure-openai-responses`、`openai-codex-responses`）共用同一个 compat 类型，因此可设在其中之一的开关，三者皆可设。`supportsDeveloperRole` 可设在 `openai-completions` 与这三者上；`thinkingFormat` 只能设在 `openai-completions`；`supportsTemperature` 只能设在 `anthropic-messages`；`supportsStrictMode` 还可达 `bedrock-converse-stream`。模型级开关若其协议并不接受，解析失败并点名该协议实际提供哪些开关；路由级开关则落在读取它的模型上、跳过其余模型，只有当路由上没有任何模型能读取它时才被拒绝。
+profile 通过可选 settings seam 每次操作重新读取：base 与用户的 `llm-pi-ai:` 设置分节按提供方合并，因此用户可以新增路由、覆盖组合路由的一个字段或把路由指向另一个代理，全部在下一个请求生效、无需重启。适配器无法服务的分节会在写入处被拒绝——`settings.mutate` 回答 `settings-rejected`——之后失效的已存储分节会保留 namespace 最后有效值。当路由集合或某路由的重试策略变化时，插件会原子地重新注册：冲突路由会让此前路由继续服务。
 
-三类键会被拒绝而非丢弃：没有任何协议声明的键（笔误）；pi-ai 已安装 catalog 为具名厂商掌管的键（`openRouterRouting`、`zaiToolStream`、`deferredToolsMode`、`sessionAffinityFormat`、`supportsOpenAIGrammarTools`、`supportsAdditionalTools`、`supportsToolSearch`、`supportsExplicitPromptCacheMode`、`supportsToolReferences`、`vercelGatewayRouting`、`sendSessionAffinityHeaders`）——需要某厂商专属开关的路由，本就是一条应当以该厂商命名的 catalog 路由；以及完全没有写值的键（`supportsDeveloperRole:`），schemastery 会把它放行为 null，若照单收下就会用空值替换已安装 catalog 的值。开放集由漂移门禁钉在 pi-ai 的四个 compat 类型上，承载它们的协议集派生自 `Model.compat` 本身，每个字段的类型也派生自上游而非重述，因此上游新增字段、给别的协议加上 compat 类型、或拓宽某个值并集，都会使构建失败，直到有人为它做出分类。
+### 从端点发现模型
 
-条目与已安装 catalog 都没有给出尺寸的模型，会采用该路由的 `defaultContextWindow`（262,144）与 `defaultMaxTokens`（32,768），因此一份只公布 id 的列表同样能产出可服务的路由。两个回退值本质上都是猜测，这正是它们作为路由字段、供网关服务更小模型的部署一次性更正的原因，而不是埋在适配器里的常量；回退值只用于给模型定尺寸，绝不会变成单次请求上限。
+插件会回答"该提供方可以提供哪些模型？"，供配置界面正在编辑或起草的路由使用。已安装目录提供的路由直接由目录回答，不发网络请求；只有目录未描述的路由才会经网络询问（`openai-completions` 与 `openai-responses` 形状）。回答是界面可以提供给用户采纳的候选元数据——不存储任何内容，`settings.yaml` 仍然是决定路由服务内容的唯一事实。
 
-请求模态的解析顺序是：条目的 `input` → 已安装 catalog 条目 → 路由的 `defaultInput`（默认 `[text]`），与上面两个容量字段的顺序和「回退值」定位完全一致。因此 catalog 模型保留 catalog 为它记录的模态，更窄的路由默认值也绝不会把它剥掉；而**未被 catalog 描述的**模型全都接受图片的网关，只需在路由上写一次 `[text, image]`，不必逐条目写。条目的空列表与缺省同义——它描述的是一个什么都不接受的模型，因此不作答，解析继续往下走——这正是当 `models` 条目点到某个 catalog 模型却不声明模态时，该模型仍保留 catalog 自有模态的原因。路由的那个则不得为空，因为它下面已经没有可以代为作答的层级。
+### 失败与恢复
 
-`[text]` 是「尚未声明」，而不是对端点的猜测——这也是为什么这里的回退值取保守值，而两个容量回退值只是取一个说得过去的值。这里没有任何环节会去询问网关实际接受什么，而两种猜错的代价并不对等：模态中不含图片时，Harness 会在图片被附加之前就拒绝，因此少声明的代价是一次点名该模型的拒绝；而多声明会接纳一张图片、再由提供方在轮次中途拒绝——此时消息已经持久化，会话便会不断重复一个不可能成功的请求。
+pi-ai 不提供的路由需要 `api`、`baseURL` 与非空 `models` 列表；无法服务的 profile 会在写入处被拒绝，并点名路由与模型。失败携带稳定 code：无法使用的凭据以 `INVALID_CREDENTIAL` 失败并点名路由与引用，`apiKeyEnv` 引用解析为空的路由以 `MISSING_CREDENTIAL` 失败，未配置模型以 `UNKNOWN_MODEL` 失败，终止性提供方失败则区分 `QUOTA` 与暂时性 `RATE_LIMIT`。`GenerateOptions.stop` 以 `UNSUPPORTED_OPTION` 被拒绝，因为 pi-ai 的通用流式 UI 无法跨提供方保证它。
 
-路由完全无法服务时解析仍会失败得响亮，并点名出问题的路由与模型：catalog 未提供的路由需要 `api`、`baseURL`，以及一个由唯一标识的模型组成的非空 `models` 列表。该解析在分节 schema 内部运行，因此无法服务的 profile 会在**写入之处**被拒绝——`settings.mutate` 以 `settings-rejected` 点名路由与模型——而不是先存下来、再悄悄让该 namespace 下每条路由失效。对于已经存下的、在此失败的分节，settings seam 会保留该 namespace 上一份可用值，因此这不会把部署卡死。`api` 接受 `supportedProtocols()` 中的协议，且仅在 catalog 无法提供协议时才需要：catalog 中不存在的模型会继承其同门模型一致同意的协议，因此向单协议 catalog 路由添加模型无需重述任何内容。
+-----
 
+<a id="understand-the-implementation"></a>
+## 理解实现
 
-`baseURL` 设定该路由下每个模型的端点，因此仍支持 `https://proxy.example.com:8443` 等私有 proxy；省略它的 catalog 路由会保留每个 catalog 模型自己的端点。在 catalog 路由上点名 `api` 会把整条路由改指到该协议，这正是部署把某个提供方在 Responses 与 Chat Completions 之间迁移的方式。
+<details>
+<summary>实现细节——点击展开</summary>
 
-`supportedProtocols()` 刻意窄于 pi-ai 的完整流式 API 集合：它只保留 profile 能用密钥、端点与标头**完整描述**的那些协议。Bedrock 要用 AWS 凭据与 region 做 SigV4 签名，Vertex 需要 project、location 与应用默认凭据，Azure 需要提供方环境外加 api-version，Codex 走 OAuth——提供它们只会交回一个无法完成认证的路由。catalog 路由仍可经自己的 provider 抵达这些协议；被拒绝的只有显式覆盖。
+本节解释适配器背后的设计；可观察行为已在[使用本包](#use-this-package)中完整说明。
 
-## 动态配置（settings + credentials）
+### 设计理念
 
-适配器经由一个 thunk **每操作读取一次** profile，而非在构造期冻结。插件在可选的 `ctx.settings` seam 上用同一份 `Config` schema 注册 `llm-pi-ai` namespace，并以其 `cordis.yml` 条目为组合 `base`；由于 `providers` 是字典，base 与用户的 `llm-pi-ai:` settings 分节**按提供方**合并：用户可以新增路由、覆盖组合路由的单个字段，或把路由指向另一个 proxy，全部在下一次请求生效，无需重启。未挂载 settings 服务时，仅由 entry 配置驱动适配器，行为不变。
+适配器建立在不可变快照与按操作解析之上。每个操作都会在第一次 `await` 前捕获整个快照——profile 加一个持有每条路由所构建 `Provider` 的 `createModels()` 集合——配置变更会构建新集合而非修改使用中的集合，因此在一个配置下开始的请求绝不会在另一个配置下结束。路由自己的凭据引用经 harness seam 解析，并以请求 `apiKey` 选项传入，pi-ai 将其视为优先级最高的 auth 覆盖——这正是快速失败（fail-loud）引用语义的所在。该覆盖未覆盖的一切都经集合自身的 auth 到达 pi-ai：凭据存储持有登录写入、刷新轮换的记录（以 `llm-pi-ai/<provider id>` 寻址），auth context 回答提供方解析时提出的 ambient 问题。两者跨快照保持稳定，因此配置变更重建集合时不会忘记谁已登录。
 
-凭据在每次流调用时通过 `apiKeyEnv` 与可选的 `ctx.credentials` seam 解析；未挂载该 seam 时，适配器只读取该引用指向的环境变量。只有完全没有点名任何凭据的 profile——仅限这一种情况——才交给 pi-ai 的环境发现。每个解析出的密钥都会在使用前去除首尾空白并校验格式，因此 HTTP 标头无法承载的值会被拒绝，而不是以语义不明的 `fetch` `TypeError` 形式浮现；这种拒绝会抛出 `LlmError('INVALID_CREDENTIAL')`，点名失败的路由与凭据引用，但绝不透露密钥的任何部分。路由集合与每条路由捕获的重试策略是注册级事实：两者任一变化时，插件都会原子地替换自己的注册（同一适配器实例，候选集合先经校验），因此某条路由若已被另一适配器占有，先前的路由会继续服务，而改回可用配置时注册会重新生效。提供方键的顺序绝不算作变化。本适配器无法服务的分节会在写入处被拒——注册的 `validate` 会解析整份 profile 集合，因此 `ctx.settings.mutate` 以 resolver 自身的错误拒绝（该协议将其报为 `settings-rejected`），什么都不会存储。已存储分节若因其他途径变得不可服务——比如外部编辑了 `settings.yaml`——则由 settings seam 保留该 namespace 最后可用的值并告警。entry 配置本身仍会使插件加载失败；而 llm 注册表拒绝的路由（已被另一适配器族占有的那种）会被记录下来，先前注册的路由继续服务。
+### 源码地图
 
-适配器通过 `ctx.llm.listModels(provider)` 公开每条已配置路由的模型。这是从请求路径所用的同一个 pi-ai `Models` 集合读取的提供方无关 selector 元数据，因此发现不会创建第二个模型注册表。`ctx.llm.resolveModelInfo(provider, model)` 会执行一次精确 descriptor 查找，并返回其身份、上下文窗口、已配置输出上限和可选思考级别，让权威元数据保留在拥有路由的适配器上，而非消费方。模型**已配置**的 `maxTokens` 会成为 seam 的 `defaultMaxTokens`，因此未点名输出上限的请求会携带部署选定的那一个；而从已安装 catalog 继承来的值是模型的输出**能力**，绝不会自行变成请求默认值。

-**没有**这份元数据的模型——条目未声明 `reasoningEfforts` 的手工声明模型，以及 pi-ai 标记为不具备推理能力的 catalog 模型——完全不公开 `reasoning`。pi-ai 会把这类模型报告为只支持 `off` 一档，但 `off` 会被翻译成*省略* reasoning 选项，而那与「不点名任何档位」产出的请求逐字节相同：选它关不掉任何东西，于是自身默认就在思考的提供方，会在界面显示 `off` 被选中的同时继续思考。把该能力报告为不可用，界面就只剩提供方默认这一项，不会再出现自相矛盾的控件。配置 profile 的 `reasoning` 值（包括 `off`）在存在时是部署默认值；省略它会保留提供方默认值。每次请求的 `GenerateOptions.reasoningEffort` 优先；未出现在确切模型能力中的档位会让**请求**在网络 I/O 前以 `UNSUPPORTED_REASONING_EFFORT` 失败，而不会被自动调整。**描述**一个模型则从不这样失败：同一提供方下各模型接受的档位并不一致，因此 `resolveModel` 对该模型拿不下的 profile 档位报告为「没有默认值」，而不是抛错。在那里抛错会让整个提供方从任何基于它构建的模型目录中消失——一个配错的 profile 字段连支持该档位的模型也一并藏起来——所以坏配置暴露在被执行处，而不是被描述处。pi-ai 的通用流选项通过省略 `reasoning` 表示 `off`。
+插件会在可配置提供方目录中声明它能认证的每个已安装目录提供方，并加入当前 profile 声明的每条路由，因此配置界面可以在任何路由存在之前提供完整目录。每个条目都携带 `declared`——pi-ai 是否在该键下不提供任何内容——因为只有适配器能区分手工声明路由与收窄目录路由。路由注册具有原子性：与其他适配器冲突的候选集合会让此前路由继续服务。零路由的裸挂载即休眠姿态：settings 分节提供 profile 前不注册任何内容，分节清空时路由随之消失。
 
-受支持的 profile 字段是 `apiKeyEnv`、`displayName`、`api`、`baseURL`、`models`、`modelOverrides`、`compat`、`defaultContextWindow`、`defaultMaxTokens`、`defaultInput`、`headers`、`reasoning`、`thinkingBudgets`、`cacheRetention`、`transport`、`timeoutMs`、`websocketConnectTimeoutMs`、`streamIdleTimeoutMs`、`maxRequestImageBytes`、`requestImagePixelBudget`、`requestImageMaxBytes` 和 `retryPolicy`。每条 profile 解析后的重试策略会随该提供方路由一同捕获；省略时使用共享的有界 normal 默认值并重试五次。流空闲间隔必须是正的有限 Node 定时器延迟，默认为五分钟，且只覆盖未完成提供方读取，不包括消费方思考时间。每条图片路由从提供方无关的规范化附件派生确定性请求版本，受 `requestImagePixelBudget`（默认总像素 2048×2048）和 `requestImageMaxBytes`（默认原始字节 1MiB）约束。读取附件前，`maxRequestImageBytes` 先按请求版本的保守上界把超预算的最旧图片替换为逐图文本；保留版本生成后再用确切 base64 长度检查。20MiB 默认值可保留十五个按 1MiB 目标生成的请求版本，并为请求正文留下余量。同一版本用于内联 base64。对应描述会公开附件 ID 和实际请求图片尺寸；只有附件提供方给出宿主对象且当前文件系统能够将其映射到工具执行环境时，描述才会加入规范化对象路径。该路径独立于请求版本及其 `variantId`。若已配置标头中有同名项，则以 Harness 应用归因为准。
+### 回放与词汇
 
-适配器强制 pi-ai SDK `maxRetries` 为零，因此一次 `stream()` 调用只会发起一次提供方请求。已移除 profile 字段 `maxRetries` 和 `maxRetryDelayMs` 会使加载失败，而不是静默倍增或隐藏单独组合的 agent（智能体）级重试预算。空闲超时会 abort SDK 的稳定请求信号，并以 `TIMEOUT` 呈现；较早的调用方 abort 仍为 `ABORTED`。
+成功 assistant 响应会存储带版本的、无损 JSON 回放状态，与产生它们的提供方和模型放在一起——响应级事实加每个流式块一条逐块条目。请求时，`LlmRuntime` 仅当同一适配器实例拥有两条路由时才传递回放状态；适配器校验它并恢复原生响应 id 与提供方签名，无法使用的状态会降级为提供方无关内容而不是让请求失败。pi-ai 工具调用参数是解析后的对象，因此适配器解析输入并重新字符串化输出，以符合 harness 原始 JSON 约定；pi-ai 流内错误事件映射为终止 `finish` 分片。
 
-## 端点询问
+</details>
 
-插件提供 `ctx.llm.registerModelDiscovery('llm-pi-ai', …)`，用来回答「这个提供方能服务哪些模型？」——针对配置界面正在编辑或起草的路由。它刻意**不是** catalog 刷新：什么都不存储，回复是界面供用户采纳的候选。`settings.yaml` 始终是唯一决定路由服务什么的东西。
+-----
 
-点名了**已安装 catalog 所提供路由**的请求，直接由该 catalog 作答，完全不联网：pi-ai 的注册表才是它自家提供方的权威列表，且携带列表端点不会公布的上下文窗口与输出上限。这类路由根本不需要 `baseURL`。只有 catalog 未描述的路由——网关、自建服务——才会经协议层询问；若它也没给端点，则会被告知去设置一个或手工填写模型。
+<a id="further-exploration"></a>
+## 进一步探索
 
-草稿携带的是用户当下键入的凭据（如果有）；已经存好凭据的路由，在配置界面上只呈现一个脱敏描述符，因此询问会解析该路由的 `apiKeyEnv`，而不是不带认证发出去、再把端点的 401 报成密钥不对。键入的密钥优先，因为那正是被测试的那一把。解析只发生在真正要联网的路径上，因此 catalog 路由作答时完全不会触碰凭据。用户提供或已存储的探测密钥也会经过同样的去除空白与格式校验：HTTP 标头无法承载的值会被立即以 `LlmError('INVALID_CREDENTIAL')` 拒绝，而不会传到 `fetch`——否则会呈现为一个和端点不可达难以区分的、语义不明的 `ByteString` 失败。
+当包级约定不够用时阅读以下页面。它们从服务约定逐步进入孪生适配器与共享类型。
 
-询问只读 `openai-completions` 与 `openai-responses`，它们「`GET /models` + bearer 认证」的形状是网关、自建服务与官方端点三方一致认可的那一种。Azure 尽管出身 OpenAI 也被排除——它用 `api-key` 标头认证并要求 `api-version` 查询参数——Codex 则走 OAuth；其余协议一律以 `DISCOVERY_UNSUPPORTED` 回答，让界面回退到手工填写，而不是把认证失败报成一个没有模型的提供方。`baseURL` 按前缀而非待解析 URL 处理，因此 `https://gateway.example/openai/v1` 这类部署路径会保留其路径段。

-多数列表只公布 id；`context_window`/`context_length` 与 `max_output_tokens`/`max_tokens` 在网关提供时会被读取，没有可用 id 的条目会被跳过而不是让整份列表失败，其余仍由采纳方补齐。回复在四兆字节上限下读取，且上限落在实际收到的字节上——端点是用户自己填的 URL，因此会先看声明长度，但绝不把它当作边界。端点不可达、凭据被拒、响应非 JSON、以及响应没有 `data` 数组，都会以 `DISCOVERY_FAILED` 失败，消息点名端点；仅当 401 或 403 时才点名凭据。读取响应体期间被取消会呈现为 `ABORTED`，与请求发出之前被取消一致。
-
-## 提供方／模型路由与回放
-
-每次解析产出一份**不可变**快照——profiles 加上一个持有各路由所建 `Provider` 的 `createModels()` 集合——每个操作都在自己第一个 `await` 之前整体捕获一份快照。配置变化会构造**新**集合，而不是改动正在被使用的那个：`Models.streamSimple()` 是惰性的，它在流首次被消费时才解析 provider，而那已在 credential await 之后，因此改动共享集合会让一个在旧配置下开始的请求在新配置下结束，或者撞上一个已不存在的 provider。这正是 seam 的每步调用冻结（`llm.prepareCall()`）能贯通到底的原因——回复途中切换模型会在下一步生效，绝不会影响在途的那一步。请求经 `Models.streamSimple()` 抵达提供方。保持 catalog 协议不变的 catalog 路由会**复用**已安装提供方，只替换其模型列表，因为该提供方持有本包无法重建的 API 实现——Bedrock 经由独立入口加载其 Smithy 模块——从零件重建会静默收窄可用提供方的范围。其余路由都由 `createProvider()` 基于 `supportedProtocols()` 背后的协议表构造，表中条目正是 pi-ai 自己的提供方工厂所用的同一批 factory。
-
-路由的 `apiKeyEnv` 密钥仍在请求抵达 pi-ai 之前经 harness 自身 seam 解析，并作为请求的 `apiKey` 选项传入——pi-ai 将其视为优先级最高的 auth 覆盖，harness 因此保住自己明确失败的引用语义。在该覆盖之下，集合携带本插件的凭据存储与 ambient auth context：已存储的登录（OAuth grant，或在 pi-ai 自己的登录提示里键入的密钥）经由它们为路由完成认证，并在存储的跨进程锁下自行刷新。存储以 `llm-pi-ai/<provider id>` 为记录地址；手写路由键若落在记录文法之外（大写、点、下划线），读取时视为「没有存储任何东西」而不是寻址错误——这样的路由无法登录（对它的记录写入会以 `LlmError('UNSTORABLE_PROVIDER_ID')` 拒绝），只能经 `apiKeyEnv` 或提供方 ambient 设置认证。完全没有点名任何凭据的路由会解析为「已配置但无密钥」，把该要求留给协议——那才是它真正所在的位置。
-
-所选模型 descriptor 提供协议实现。这包括原生 API 差异，例如 descriptor 使用 Responses API 而非 Chat Completions 的 OpenAI 模型；harness 适配器不会按模型名称硬编码端点选择。
-
-成功的 assistant 响应会将经版本化的无损 JSON 回放状态与生成该响应的提供方和模型一同存储，其形式是 `ReplayEnvelope`：一个响应级半区（kind、版本、API、路由、响应 id、原生停止原因），加上每个流式块一条、携带该块 signature 的逐块条目。逐块对齐正是 `BlockAssembler` 在组装丢弃某个块（`max-tokens` 下的工具调用）时裁剪的对象，因此存储的条目始终描述存储的内容——保留的块保有其 signature。请求时，`LlmRuntime` 只有在历史提供方路由与目标提供方路由当前由同一个 `PiAiAdapter` 实例拥有时，才会传递回放状态。即使目标提供方或模型改变，适配器也会验证状态并恢复 pi-ai 响应 id 与提供方 signature；随后由 pi-ai 判定目标 API 可以复用哪些元数据。没有回放状态的历史会被转换为外来的、与提供方无关的内容，绝不伪装为原生 pi-ai 响应。
-
-持久化内容是权威记录；回放状态只负责恢复原生保真度。当前构建无法使用的已存状态——其他适配器的 kind、其他版本（包括旧日志携带的平铺前信封形式）、格式错误的元数据、消息与回放状态之间的提供方／模型不匹配，或内容／块不匹配——会把这一条 assistant 消息降级为同样的外来提供方无关转换而不是让请求失败，插件通过其 `onReplayDegrade` 钩子记录 `INVALID_REPLAY_STATE` 诊断。
-
-## 词汇差异
-
-- pi-ai 工具调用参数是已解析对象；harness 存储原始 JSON 字符串。适配器会解析输入，并将输出重新字符串化。
-- pi-ai 将失败报告为流内错误事件；它们会映射到 `finish {kind:'error'|'aborted', failure}` 分片。提供方特定错误文本会区分终止型 `QUOTA` 与暂时型 `RATE_LIMIT`，针对已解析模型上下文窗口评估的文本与 usage 信号则将溢出规范化为 `CONTEXT_WINDOW_EXCEEDED`。终止时的 `stop` 若消息不含内容块，则会映射为 `finish {kind:'error'}`，code 为 `EMPTY_RESPONSE`（默认策略会重试），而非成功空消息。
-- pi-ai 将推理 token 折叠到输出 usage 中；没有可映射的独立推理计数。它的精确 `totalTokens` 值会原样保留。
-- pi-ai 的 `off` 思考级别会原样穿过 Harness 能力 seam，并在分派时变为被省略的 pi-ai 通用 `reasoning` 选项。
-- `GenerateOptions.stop` 会以 `UNSUPPORTED_OPTION` 被拒绝，因为 pi-ai 的通用流式输出接口无法保证所有提供方都支持它。
-
-## 应用归因
-
-每个请求都携带 dsh-llm `attributionHeaders()` 的共享归因标头，并通过 pi-ai `headers` 流选项合并。不会合成提供方特定应用归因标头。详见 [dsh-llm § 应用归因](../llm/README.zh.md#app-attribution-attributionts)。
-
-## 依赖体量
-
-pi-ai 会安装多个提供方 SDK，并延迟加载 catalog 模型所选的 SDK。该可选适配器包将依赖体量隔离在自身范围内。

-## 已知限制与暂缓事项
+## 已知限制与延期工作
 
-- **`maxRequestImageBytes` 只统计 base64 图片载荷**：文本、工具、图片描述和 JSON 结构不计入上限，因此该值必须低于网关请求体上限并留出余量。offload 是确定性请求投影，不记录为会话事件。
-- **一次登录只存活于发起它的进程中**：授权尝试不可持久，登录途中刷新页面会丢弃它，人需要重来。登出即对已存储记录执行 `deleteRecord`，它只在本地遗忘而不通知签发方。
-- **提供方自带的凭据发现经由本插件的 ambient context 作答**：不指定凭据的路由交由 catalog 提供方自行解析，它会询问环境值（`AZURE_OPENAI_API_KEY`、`AWS_PROFILE` 以及各提供方自己的那一组）与本地凭据文件是否存在。两类问题都在这里作答：先查凭据 seam 再查进程环境，文件存在性则按宿主进程的文件系统判断并展开 `~`。它做不到的是*读取*凭据文件的内容——自行解析 `~/.aws/credentials` 的提供方是直接读盘的，不经过 seam。
-- **settings 能新增或覆盖路由，但不能移除组合路由**：用户层合并在组合 `base` 之上，因此删除 `cordis.yml` 提供的提供方属于组合变更；对该 namespace 执行 `replace` 只会重置用户层。
-- **分层合并对字典键没有删除语义**：settings seam 把组合 `base` 与用户层按键递归合并，因此 base 声明的某个 `reasoningEfforts` 档位、`modelOverrides` 条目或 `compat` 字段，用户层只能覆盖、无法移除——而 `reasoningEfforts` 里缺席本身*就是*语义（「不提供」），于是 base 声明过的档位会一直被提供。只有 `cordis.yml` entry config 为用户层正在编辑的同一模型声明了按模型推理字段才会触发；受支持的姿态是把这些字段留给 settings 文档（shipped 组合以 dormant 方式挂载该适配器），且 `models` 列表是数组、整体替换，这是带内的解决办法。
-- **`headers` 可能承载一条脱敏器看不见的凭据**：profile 的 `headers` 是纯字符串字典，因此设在其中的 `Authorization` 或 `api-key` 会被脱敏后的 `describe()` 原样返回，并被任何配置 UI 渲染出来。请把凭据存为 `apiKeyEnv` 引用；把该字典整体改为只写与其余[协议边界工作](../llm/README.zh.md#known-limitations-and-deferred-work)一并暂缓。
-- **路由的 catalog 不会自我刷新**：catalog 就是 `settings.yaml` 所写的内容，因此模型列表的新鲜度只到最近一次编辑为止。这里没有任何环节会去问提供方它服务哪些模型；路由要多一个模型，得有人写进去。
-- **每条路由只有一种协议格式**：`api` 作用于整条路由，因此混合协议的 catalog 路由（跨 Responses 与 Chat Completions 的 OpenAI 式 catalog）无法承载另一种协议的模型，向这类路由添加它未描述的模型必须点名 `api` 并把全部模型一起迁过去。把该提供方拆成两个路由键是变通办法。
-- **模态声明不经验证**：没有任何环节会去询问端点接受什么，因此声明了网关并不提供的 `image` 的模型会在 prompt 准入后被提供方拒绝。持久图片会留在历史中，同一个错误声明的模型可能再次失败。系统仍允许切换到纯文本模型，因为共享 LLM 运行时会在该次请求中把图片引用投影为稳定文本。
-- **未认证路由取决于其协议**：不点名凭据会让路由解析为「已配置但无密钥」，但 pi-ai 的 OpenAI 兼容实现仍要求 API key 或 `Authorization` 标头，因此无鉴权的本地服务需要一个由 `apiKeyEnv` 引用的占位凭据，或在 `headers` 中给出 `Authorization` 条目。
-- **不支持 `GenerateOptions.stop`**：pi-ai 的通用流选项无法保证所有提供方都支持 stop sequence，因此适配器会拒绝该字段。
-- **历史中的 `system` 消息使用 pi-ai 通用上下文转换**：提供方特定位置由 pi-ai 决定，而非由 harness 拥有的协议覆盖决定。
-- **无法获取提供方 HTTP 状态**：pi-ai 错误事件不会在所有提供方上公开稳定 HTTP 状态；失败只公开稳定 harness 错误 code。
-- **重试策略由提供方持有，而不是 SDK 重试**：每个提供方 profile 都可以提供嵌套的 `retryPolicy`；省略时解析为 normal 模式并重试五次，`dsh-llm-retry` 会在 agent 的失败步骤扩展点上执行有效路由策略。pi-ai SDK 重试仍保持禁用，因此持久化的 agent 步骤与 `llm/retry` 事件记录每次可见尝试，直接 `ctx.llm.stream()` 调用仍只尝试一次。

+description: "The retry executor for users and maintainers configuring provider-routed model-request recovery at durable agent-step boundaries."
+kind: "package-reference"
+---
+
+# @deepseek-ai/dsh-llm-retry
 
 English | [中文](README.zh.md)
 
-Function plugin that applies exact-provider retry policy through the agent loop's closed-step `agent/request-error` waterfall. It does not wrap `ctx.llm.stream()`: every adapter call remains one provider attempt, and every retry opens a fresh numbered turn.
+## Summary
 
-Each provider adapter owns an optional nested `retryPolicy`, captured when its route registers on `ctx.llm` and carried with each call that reaches that registration's final adapter boundary. An in-flight failure retains that serving policy if the route is later disposed or replaced; a failure before any final adapter is selected has no provider policy and delegates. Omission uses normal mode: five retries for `EMPTY_RESPONSE`, `RATE_LIMIT`, `SERVER`, `TIMEOUT`, and `TRANSPORT`, with bounded exponential backoff from 500 ms to 10 seconds and 10 percent jitter. `EMPTY_RESPONSE` is the adapters' classification of a degenerate provider completion that produced no durable content, so repeating it is safe. A normal policy can change its finite budget, eligible codes, and backoff. Always mode asks downstream recovery first, then retries every model-request failure without an attempt limit; success, cancellation, or plugin disposal stops it after active delegated recovery reaches quiescence.
+`@deepseek-ai/dsh-llm-retry` is the retry executor for failed model requests: it applies each provider's resolved retry policy at the agent loop's open-step `agent/request-error` extension point, so every retry re-runs the same step inside the same open turn over the same durable history. It does not wrap the streaming call itself — every adapter call remains one provider attempt, and direct `ctx.llm.stream()` consumers stay single-attempt. Retry scheduling is durable: the plugin appends `llm/retry` events to the session log before waiting, and cancellation during backoff leaves the log consistent. Normal mode retries a bounded set of failure codes up to `maxRetries` with exponential backoff; always mode asks downstream recovery first, then retries every failure without an attempt limit.
 
-Both modes use bounded exponential backoff with symmetric jitter. A valid `providerRetryAfterMs` at or below `maxDelayMs` replaces local backoff without jitter. An over-cap provider delay makes normal mode delegate, while always mode uses its configured local backoff so it cannot terminate on that instruction.

-Before waiting, the plugin appends a non-surface `llm/retry` event with the shared `retryId`, provider, mode, canonical resolved-policy key, failure, and scheduled delay. Its payload is available from the browser-safe `@deepseek-ai/dsh-llm-retry/types` subpath, so remote renderers can consume the durable status without loading the policy runtime. The key includes every behavior-affecting field and sorts normal-mode codes because eligibility uses set membership. Retry numbers continue only across events with the same provider and complete policy key, so a route replacement with different limits, code membership, or backoff starts its own history. Normal events include the finite maximum; always events omit it, and UIs render `∞`. When the wait completes, the plugin appends `llm/retry-started` with the same `retryId`, turn, step, and retry number immediately before returning `{ kind: 'retry' }`; cancellation during backoff writes no started event. The loop then closes the failed turn and opens a retry turn over the same durable history. Cancellation and plugin disposal abort active backoff, drain active delegated recovery before applying the abort, and make a callback captured before disposal fail closed.

-The separately published `./invariant` companion checks that every scheduled retry names the current open turn and latest closed step, matches the failed request's durable provider, carries non-empty provider and policy identities, has mode-specific bounds, a unique step record, the correct provider-policy retry number, and a bounded timer delay. It also requires each `llm/retry-started` event to name one prior scheduled attempt with the same `retryId`, turn, step, and retry number, and rejects repeated started events. Full jitter may schedule zero milliseconds at its lower boundary.

+## Use this package
+
+Mount this plugin when agent runs should recover from transient model-request failures — rate limits, server errors, timeouts, transport errors — instead of ending the turn. It is the executor: the retry policy itself lives on each provider adapter's configuration, and this package has no configuration of its own.
+
+### When to choose it
+
+Choose it when a composition runs the agent loop and wants durable request recovery. The plugin is a function plugin with no config; provider adapters such as `dsh-llm-deepseek` and `dsh-llm-pi-ai` own the `retryPolicy` for their routes, and multi-provider adapters place it inside each provider profile. Skip it when calls go through `ctx.llm.stream()` directly without the agent loop: those consumers remain single-attempt because a raw stream cannot separate already-emitted chunks durably.

-The executor has no policy config. Multi-provider adapters such as `dsh-llm-pi-ai` place `retryPolicy` inside each provider profile, avoiding a second provider-name list.
+Omission of `retryPolicy` uses normal mode: five retries for `EMPTY_RESPONSE`, `RATE_LIMIT`, `SERVER`, `TIMEOUT`, and `TRANSPORT`, with bounded exponential backoff from 500 ms to 10 seconds and 10 percent jitter. Normal mode can change its finite budget, eligible codes, and backoff; always mode asks downstream recovery first, then retries every model-request failure without an attempt limit, stopping only on success, cancellation, or plugin disposal.
 
+### What you can observe
+
+Each scheduled retry is durable before its wait: the plugin appends a non-surface `llm/retry` event carrying the retry id, provider, mode, policy key, failure, and scheduled delay, then a `llm/retry-started` event immediately before the retry begins. A valid `Retry-After` from the provider replaces local backoff when it fits the policy bounds. When the wait completes, the loop re-runs the failed step inside the same open turn over the same durable history, so the retried request is reconstructable from the session log exactly like the original. Cancellation or plugin disposal aborts active backoff, drains active delegated recovery, and makes a callback captured before disposal fail closed.
+
+### Failures and recovery
+
+A failure before any final adapter is selected has no provider policy and delegates downstream unchanged. In normal mode, a failure code outside the eligible set, or an exhausted budget, delegates; in always mode, an over-cap provider delay uses the configured local backoff so the policy cannot terminate on that instruction. Nothing here is model-visible: no retry event, delay, provider error, or failed partial output reaches the model or derived messages.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design behind the executor; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The executor is built on one rule: **durable before wait, open-step boundaries.** A retry is scheduled through the session log before any timer starts, so a crash or cancellation never leaves an invisible pending retry. Recovery runs on the agent loop's `agent/request-error` waterfall, the open-step extension point, rather than wrapping `ctx.llm.stream()` — a raw stream cannot separate already-emitted chunks durably, while the loop can re-run the failed step inside the same open turn.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | The function plugin: waterfall listener, policy lookup, backoff, durable event appends |
+| [`src/history.ts`](src/history.ts) | Durable retry-history lookup from the session log |
+| [`src/types.ts`](src/types.ts) | Browser-safe `llm/retry` and `llm/retry-started` event payload types |
+| [`src/brand.ts`](src/brand.ts) | The `RetryId` brand shared by the event payloads |
+
+### Recovery flow
+
+A failed step arrives on the waterfall with its provider and resolved policy. Always mode settles downstream recovery first and honors a downstream `retry` decision; normal mode first checks that the failure code is eligible and the budget is not exhausted. The plugin computes the delay — provider `Retry-After` when valid and within bounds, otherwise local bounded exponential backoff with symmetric jitter — appends the `llm/retry` event, waits on a cancellable timer, appends `llm/retry-started`, and returns `{ kind: 'retry' }`. The loop then re-runs the failed step inside the same open turn over the same durable history.
+
+### Waterfall composition
+
+The plugin is one listener in the `agent/request-error` waterfall. Always mode's "downstream first" posture means a later policy that ignores cancellation and never settles also prevents fallback, turn quiescence, and plugin disposal from completing; success, cancellation, or disposal stops always mode after active delegated recovery reaches quiescence.

 ### Model-request recovery

-No retry event, delay, provider error, or failed partial output is model-visible. The retry turn reconstructs the same explicit provider/model request from durable surface history unless a downstream recovery policy deliberately changes that surface; failed chunks never enter derived messages.

+These limits define where the executor stops and future work begins. They are current package constraints, not a general retry comparison or a task backlog.
+
 - **Agent turns are the only retry boundary** — direct `ctx.llm.stream()` consumers remain single-attempt because a raw stream cannot separate already-emitted chunks durably.
 - **Always mode retries permanent failures** — authentication, quota, invalid-request, protocol, and unrecoverable context errors continue until success, cancellation, or disposal; deployments own provider-specific cost and latency controls.
 - **Finite plugin budgets add** — normal mode counts only its configured codes and exact provider policy, while context-overflow compaction owns a separate budget. Any overlapping policy must define registration-order behavior.
 - **Recovery policies compose by waterfall order** — always mode accepts a downstream retry before applying its fallback. A later policy that ignores cancellation and never settles also prevents fallback, turn quiescence, and plugin disposal from completing.
 - **`llm/retry` records scheduling, not completion** — later step and turn events establish success, exhaustion, or cancellation.

-一个函数插件，通过 agent loop（智能体循环）在已关闭步骤上触发的 `agent/request-error` waterfall（瀑布式事件）应用确切提供方重试策略。它不包装 `ctx.llm.stream()`：每次适配器调用仍是一次提供方尝试，每次重试都会开启新的编号轮次。
+## 概述
 
-每个提供方适配器都拥有可选的嵌套 `retryPolicy`；路由在 `ctx.llm` 上注册时会捕获该策略，任何到达该注册最终适配器边界的调用都会携带它。如果之后释放或替换路由，进行中的失败仍会保留当时为其提供服务的策略；在选中任何最终适配器前发生的失败没有提供方策略，会继续委托。省略策略时使用 normal mode：为 `EMPTY_RESPONSE`、`RATE_LIMIT`、`SERVER`、`TIMEOUT` 和 `TRANSPORT` 重试五次，并采用从 500 ms 到 10 秒的有界指数退避与 10% jitter。`EMPTY_RESPONSE` 是适配器对未产生任何持久内容的退化提供方完成所作的分类，因此可安全重复。normal 策略可以更改其有限预算、符合条件的 code 和退避配置。always mode 会先请求下游恢复，再无次数上限地重试每个模型请求失败；成功、取消或插件 dispose（资源释放）会在活跃的委托恢复完全停稳后终止它。
+`@deepseek-ai/dsh-llm-retry` 是失败模型请求的重试执行器：它在 agent loop 的打开步骤 `agent/request-error` 扩展点上应用各提供方解析后的重试策略，因此每次重试都会在同一个打开的轮次内重跑同一个步骤（基于同一份持久历史）。它不包装流式调用本身——每次适配器调用仍是一次提供方尝试，直接 `ctx.llm.stream()` 消费方仍是单次尝试。重试调度是持久的：插件在等待之前就把 `llm/retry` 事件追加进会话日志，退避期间取消会让日志保持一致。normal mode 以指数退避重试一组有界的失败 code，最多 `maxRetries` 次；always mode 先询问下游恢复，然后无尝试上限地重试每个失败。
 
-两种 mode 都使用带对称 jitter 的有界指数退避。有效 `providerRetryAfterMs` 不超过 `maxDelayMs` 时会替换本地退避，并且不加 jitter。超出上限的提供方延迟会使 normal mode 继续委托；always mode 则改用已配置的本地退避，避免该指令终止重试。
+## 目录
 
-等待前，插件会追加一条不进入表层的 `llm/retry` 事件，其中包含共享 `retryId`、提供方、mode、已解析策略的规范 key、失败和计划延迟。该载荷由可安全用于浏览器的 `@deepseek-ai/dsh-llm-retry/types` 子路径导出，因此远程渲染器无需加载策略运行时即可使用该持久状态。该 key 包含所有影响行为的字段，并对 normal mode 的 code 排序，因为合格性采用集合成员关系判断。只有提供方与完整策略 key 都相同的事件才会延续重试编号；因此，用限制、code 成员关系或退避不同的路由替换后，会开始自己的历史。normal 事件包含有限上限；always 事件省略该上限，UI 会渲染 `∞`。等待完成时，插件会在返回 `{ kind: 'retry' }` 前立即追加 `llm/retry-started`，其中带有相同的 `retryId`、轮次、步骤与重试编号；退避期间取消则不会写入 started 事件。随后循环关闭失败轮次，并在同一持久历史上开启重试轮次。取消与插件 dispose 会中止活跃退避，在应用中止前等待活跃的委托恢复结算，并使 dispose 前捕获的 callback 只能以失败结束。

-单独发布的 `./invariant` 配套模块会检查每个已调度重试是否指向当前开启轮次及其最新已关闭步骤，是否与失败请求的持久提供方匹配，是否携带非空的提供方与策略标识，是否满足 mode 特定边界，是否拥有唯一步骤记录和正确的提供方策略重试编号，以及是否携带有界定时器延迟。它还要求每个 `llm/retry-started` 事件通过相同的 `retryId`、轮次、步骤与重试编号指向一个先前调度的尝试，并拒绝重复的 started 事件。full jitter 可以在下界调度为零毫秒。

+## 使用本包
+
+当 agent 运行应从暂时性模型请求失败——速率限制、服务端错误、超时、传输错误——中恢复而不是结束轮次时，挂载本插件。它是执行器：重试策略本身位于各提供方适配器的配置上，本包没有任何自己的配置。
+
+### 何时选择
+
+当组合运行 agent loop 并需要持久请求恢复时选择它。本插件是无配置的函数插件；`dsh-llm-deepseek` 与 `dsh-llm-pi-ai` 等提供方适配器拥有各自路由的 `retryPolicy`，多提供方适配器把它放进每个 provider profile。当调用不经 agent loop、直接走 `ctx.llm.stream()` 时跳过它：这些消费方仍是单次尝试，因为原始流无法持久地区分已发出的分片。
+
+### 最小配置

@@ -26,28 +47,103 @@
 - name: '@deepseek-ai/dsh-llm-retry'
 ```
 
-执行器没有策略配置。`dsh-llm-pi-ai` 等多提供方适配器会把 `retryPolicy` 放在每个提供方 profile 内，避免维护第二份提供方名称列表。
+省略 `retryPolicy` 时使用 normal mode：对 `EMPTY_RESPONSE`、`RATE_LIMIT`、`SERVER`、`TIMEOUT` 与 `TRANSPORT` 最多重试五次，退避从 500 毫秒到 10 秒、带 10% 抖动。normal mode 可以更改其有界预算、合格 code 与退避；always mode 先询问下游恢复，然后无尝试上限地重试每个模型请求失败，只在成功、取消或插件释放时停止。
 
+### 你可以观察到什么
+
+每次计划的重试在等待前就是持久的：插件会先追加携带重试 id、提供方、模式、策略键、失败与计划延迟的非 surface `llm/retry` 事件，然后在重试开始前立即追加 `llm/retry-started` 事件。提供方给出且符合策略边界的有效 `Retry-After` 会替换本地退避。等待完成后，loop 会在同一个打开的轮次内重跑失败步骤，仍基于同一份持久历史，因此重试请求与原始请求一样可以从会话日志重建。取消或插件释放会中止进行中的退避、排空活动中的委派恢复，并让释放前捕获的回调快速失败。
+
+### 失败与恢复
+
+在任何最终适配器被选中之前发生的失败没有提供方策略，原样委派下游。normal mode 中，不在合格集合内的失败 code 或已耗尽的预算会委派；always mode 中，超上限的提供方延迟使用配置的本地退避，因此策略不会因该指令终止。这里没有任何模型可见内容：重试事件、延迟、提供方错误或失败的部分输出都不会到达模型或派生消息。

+
+### 设计理念
+
+执行器建立在一条规定之上：**先持久、后等待，打开步骤边界。** 任何定时器启动之前，重试就已通过会话日志计划，因此崩溃或取消永远不会留下不可见的待处理重试。恢复运行在 agent loop 的 `agent/request-error` waterfall（打开步骤扩展点）上，而不是包装 `ctx.llm.stream()`——原始流无法持久地区分已发出的分片，而 loop 可以在同一个打开的轮次内重跑失败步骤。

+
+### 恢复流程
+
+失败步骤连同其提供方与解析后的策略一起到达 waterfall。always mode 先结算下游恢复，并遵循下游的 `retry` 决定；normal mode 先检查失败 code 是否合格、预算是否未耗尽。插件计算延迟——有效且在边界内的提供方 `Retry-After`，否则带对称抖动的本地有界指数退避——追加 `llm/retry` 事件，在可取消定时器上等待，追加 `llm/retry-started`，然后返回 `{ kind: 'retry' }`。loop 随后在同一个打开的轮次内重跑失败步骤（仍基于同一份持久历史）。
+
+### Waterfall 组合
+
+本插件是 `agent/request-error` waterfall 中的一个监听器。always mode 的"下游优先"姿态意味着，之后忽略取消且永不结算的策略也会阻止回退、轮次完全停稳与插件释放完成；成功、取消或释放会在活动委派恢复达到完全停稳后停止 always mode。

-Provider-neutral LLM vocabulary and abstract service. This package defines the canonical language spoken by the agent loop, session logs, and every plugin.
+## Summary
 
-## Service: `LlmRuntime` (ctx key: `llm`)
+`@deepseek-ai/dsh-llm` is the provider-neutral model-call service at the center of the harness's LLM capability. Every composition that streams a request to a model provider goes through it, and it owns the shared vocabulary — messages, content blocks, and raw stream chunks — that the agent loop, session log, and every plugin speak. With it you can register provider adapters, stream one model call, list and discover models, resolve exact-model metadata and call defaults, and capture each provider's retry policy; every request is logged so it stays reconstructable from the session log. It executes no retries and owns no provider wire logic: adapters translate their provider's format, and the optional `dsh-llm-retry` package re-runs failed requests at durable step boundaries. Requests are deep-frozen before dispatch, so middleware and adapters can read them but never rewrite them.
 
-An adapter registry plus a single streaming call API, interceptable via a waterfall event.

-Each provider adapter supplies its resolved route policy. Omitting provider configuration uses bounded normal mode with five retries after the first request. Layered configuration may retain `maxRetries` or `retryableCodes` after changing `mode` to `always`; resolution ignores those inactive normal-mode fields and captures a pure always policy. This service stores the effective policy but does not execute retries.

+## Use this package
 
-- `ctx.llm.registerAdapter(providers: string[], adapter: LlmAdapter): AdapterRegistrationHandle` Register one adapter instance for the given provider routes. Registration is all-or-nothing, and is disposed with the calling fiber. The returned disposer also carries `replace(providers)`: the candidate route set is validated in full before anything moves, so a conflict with another adapter leaves the current routes registered and serving, and the swap itself is one synchronous section with no observable gap. `replace([])` is legal — a registration holding zero routes — unlike an empty initial registration.
-- `ctx.llm.listProviders(): LlmProviderInfo[]` Describe registered provider routes in registration order.
-- `ctx.llm.registerConfigurableProviders(entries: readonly LlmConfigurableProvider[]): DirectoryRegistrationHandle` Declare provider routes an adapter plugin can activate through configuration — registered or dormant — each naming its owning settings namespace and the path to its profile inside that section. All-or-nothing (`INVALID_DIRECTORY`/`DUPLICATE_DIRECTORY`), disposed with the calling fiber. The handle also carries `replace(entries)`: the candidate set is validated in full before anything moves, so an entry another registration already declares leaves the current set intact, and an empty array is legal there. A plugin whose declared set follows its configuration must use `replace` rather than disposing and re-registering — the latter strands the directory empty whenever the new set is refused.
-- `ctx.llm.listConfigurableProviders(): LlmConfigurableProvider[]` List the declared directory in declaration order; configuration surfaces merge it with `listProviders()` to mark each entry live or dormant. An entry may carry `declared` — whether the owning adapter knows that route only because configuration named it. Only the adapter can answer, so absence means "this adapter draws no such distinction", never "shipped".
-- `ctx.llm.registerModelDiscovery(settingsNs: string, discover): () => void` Offer to interrogate provider endpoints for the settings namespace this plugin owns. One offer per namespace (`INVALID_DISCOVERY`/`DUPLICATE_DISCOVERY`), disposed with the calling fiber.
-- `ctx.llm.listModelDiscoveryNamespaces(): string[]` List the namespaces that can interrogate an endpoint, so a surface offers the action only where it works.
-- `ctx.llm.discoverModels(settingsNs: string, request: LlmModelDiscoveryRequest): Promise<LlmDiscoveredModel[]>` Ask one endpoint which models it advertises.
-- `ctx.llm.providerRetryPolicy(provider: string): ResolvedRetryPolicy` Return the provider-owned retry policy captured during registration, with normal defaults resolved.
-- `ctx.llm.listModels(provider: string): Promise<LlmModelInfo[]>` Discover the models one registered provider currently advertises.
-- `ctx.llm.resolveModelInfo(provider: string, model: string, signal?: AbortSignal): Promise<LlmResolvedModelInfo>` Resolve validated exact-model identity plus available context, output-default, and reasoning metadata from the owning adapter, with optional cancellation for asynchronous adapters.
-- `ctx.llm.resolveCallConfig(config: LlmCallConfig, signal?: AbortSignal): Promise<LlmCallConfig>` Validate an explicit effort and materialize adapter-configured call defaults without clamping.
-- `ctx.llm.prepareCall(config: LlmCallConfig, signal?: AbortSignal): Promise<PreparedLlmCall>` Resolve a config plus detached context and modality metadata and markers for fields supplied by adapter defaults in one exact-model lookup, then capture the adapter's matching dispatch generation and immutable retry policy as one cancellable, one-shot call.
-- `ctx.llm.stream(options: GenerateOptions): AsyncIterable<StreamChunk>` Stream one model call as raw chunks (token-level deltas). Consumers assemble the chunks into blocks/messages with `BlockAssembler`.
+Any composition that calls a model provider — an agent loop, a session-title generator, a compaction summarizer — streams its requests through this service. Mount it together with at least one provider adapter; the service itself has no configuration and no provider wire code.
 
-`LlmRuntime` normalizes failures from final adapter selection, synchronous dispatch, iterator construction, and iteration into the stream protocol's single terminal form: `finish { kind: 'error' | 'aborted', failure }`. A failure after partial deltas may leave content blocks open; consumers discard that incomplete output. Errors from `llm/stream` middleware, nested calls, adapter cleanup, and downstream consumers remain thrown because they are plugin or consumer failures rather than model-request outcomes. A prepared call exposes the immutable retry policy captured with its exact adapter registration; a route handled entirely by middleware has no serving policy.
+### When to choose it
 
-Interrogating an endpoint is configuration-time work over a *draft*, keyed by settings namespace rather than by provider route — the provider a surface is adding does not exist yet, so there is no route to name. The request may still *name* a route it is editing, and an adapter that already describes that route answers from its own knowledge without a network call; `baseURL` is optional and one of the two is required. The request otherwise carries the endpoint, the protocol, and a credential the harness uses for that one interrogation and never stores — nothing here reads or writes settings or credentials, and the reply is candidate metadata a surface may offer for adoption, never a registered catalog. `LlmDiscoveredModel` makes every field but `id` optional because most provider listings disclose an id and nothing else; a surface adopting one still owes the capacities its adapter requires. Duplicate and unusable ids are dropped, an unserved namespace fails with `NO_DISCOVERY`, and a request naming neither a route nor an endpoint fails with `INVALID_DISCOVERY`.
+Choose this package whenever a plugin or composition needs to call a model: it is the only supported path into provider adapters, and it keeps one vocabulary across the loop, the session log, and every consumer. Do not reach for it when you need provider-specific wire behavior (that belongs in an adapter such as `dsh-llm-deepseek` or `dsh-llm-pi-ai`) or retry execution (that belongs in `dsh-llm-retry`).
 
-Provider and model metadata is a discovery surface, not a routing whitelist. `registerAdapter()` still owns provider exclusivity and captures the adapter's retry policy for each route, while an adapter may accept model ids absent from `listModels()`; consumers must not reject a request because its model is unlisted. Returned selector metadata is detached and invalid or duplicate adapter entries fail with `INVALID_ADAPTER` or `INVALID_CATALOG`.
+### Minimal composition
 
-Every topology commit point — adapter routes registering or disposing, directory entries appearing or withdrawing — emits the payload-free `llm/adapters-updated` event after the mutation, so consumers re-read `listProviders()`/`listModels()`/`listConfigurableProviders()` instead of polling. Observer failures are contained (logged, non-vetoing); only `INVARIANT`-coded failures rethrow after the fan-out.
+Mount the service and at least one adapter, then select the provider by name in every request:
 
-Exact-model metadata is a separate correctness query, not a catalog decoration or global LLM setting. `resolveModelInfo()` asks the adapter that owns the exact provider/model route once; an adapter can describe an unlisted dynamic model, and absent `context`, `defaultMaxTokens`, or `reasoning` fields preserve unknown capacity, provider-owned output defaults, or unavailable reasoning capability. Invalid identity, context, output default, or reasoning metadata fails with `INVALID_MODEL_INFO`, `INVALID_MODEL_CONTEXT`, `INVALID_MODEL_MAX_TOKENS`, or `INVALID_MODEL_REASONING`.
+```yaml
+- name: '@deepseek-ai/dsh-llm'
+- name: '@deepseek-ai/dsh-llm-deepseek'
+  config:
+    apiKeyEnv: DEEPSEEK_API_KEY
+```
 
-`defaultMaxTokens` is an adapter-configured per-request output cap, not a model hard limit. `resolveCallConfig()` materializes it only when the request omits `maxTokens`; an explicit cap wins. Reasoning identifiers are opaque adapter-owned strings rather than a core enum: the same resolution accepts only an exact advertised identifier, materializes `defaultEffort` when present, and otherwise preserves the provider default. Asynchronous model resolvers receive the caller's signal and must settle promptly after cancellation. `prepareCall()` additionally exposes detached context and input-modality metadata, reports which `maxTokens` and `reasoningEffort` fields it materialized in `adapterDefaults`, and binds those facts to the adapter generation that performs terminal dispatch. HMR or dynamic settings therefore cannot combine one generation's image capability with another generation's endpoint; reusing the one-shot handle or changing its call-config fields fails with `INVALID_PREPARED_CALL`. An unsupported explicit or configured effort fails with `UNSUPPORTED_REASONING_EFFORT` before provider I/O.
+A stream returns token-level chunks and always ends with one terminal `finish` chunk; `BlockAssembler` turns the chunks into content blocks and messages, and the loop logs each chunk for replay:
 
-### Events
+```text
+for await (const chunk of ctx.llm.stream({
+  provider: 'deepseek-official',
+  model: 'deepseek-v4-flash',
+  messages: [createUserMessage({ content: [{ type: 'text', text: 'Hello' }] })],
+})) {
+  // chunks: block-start, text-delta, ..., usage, finish
+}
+```
 
-| Event | Mode | Purpose |
-|---|---|---|
-| `llm/stream` | waterfall | Intercept/wrap every streaming model call for caching, logging, or routing |
+After a successful mount, `ctx.llm.listProviders()` reports the registered routes in registration order.
 
-### Extension points
+### What you can do
 
-- Subclass `LlmAdapter` and call `ctx.llm.registerAdapter(providers, adapter)` to add one or more provider routes. `GenerateOptions.provider` selects the adapter; `GenerateOptions.model` is adapter-owned and may be resolved dynamically. Override `providerRetryPolicy()` to supply provider-owned recovery configuration, `providerInfo()` and asynchronous `listModels()` to expose selector metadata, then implement `resolveModel()` when exact identity, capacity, an output default, or selectable reasoning efforts are available; an asynchronous resolver must honor its optional cancellation signal. The defaults use bounded normal retry policy, use the route and model ids as names, advertise no models, and return no capacity, output default, or reasoning metadata.
-- Wrap `llm/stream` via `ctx.on()` waterfall listeners for caching, logging, or routing. A wrapper that retries after emitting a chunk has no durable attempt boundary; shipped agent retry policy therefore uses `agent/request-error` instead.
+- **Stream one model call** — `ctx.llm.stream(options)` yields raw chunks (token-level deltas) for any registered provider and model; consumers assemble them with `BlockAssembler`.
+- **Register provider adapters** — an adapter owns one or more provider routes, and its registration captures that route's retry policy; registering the same route twice fails with `DUPLICATE_ADAPTER`.
+- **Expose and activate providers through configuration** — adapters declare configurable-provider routes plus a settings namespace, so configuration surfaces can activate dormant providers and edit connection facts without a restart.
+- **Discover and resolve models** — list the models an adapter advertises, interrogate an endpoint for the models it serves, and resolve one exact model's context window, output default, reasoning efforts, and input modalities.
+- **Validate call config** — an explicit or configured reasoning effort is checked against the exact model before any provider I/O, and an adapter-configured output cap is materialized when the request omits one.
 
-### Messages (`message.ts`) and content blocks (`types.ts`)
+### Failures and recovery
 
-`Message` is the shared immutable value used by delivery, durable history, and model requests. Every message has a required `MessageId`, role, content, and typed source from creation onward. `createMessage(input)` mints the identity and returns a detached deep-frozen value; `createUserMessage({ content, source })` fixes the user role; `createAssistantMessage({ content, source })` fixes the assistant role and model source kind; `createToolResultMessage({ callId, content, isError })` fixes the user role and couples the tool source to its result block; `freezeMessage(message)` imports an identity that already exists and never replaces it. Message rewrites preserve the identity and produce another frozen value. Browser code imports these value constructors from the dependency-minimal `@deepseek-ai/dsh-llm/message` entry instead of the service-bearing package root.
+Every stream ends in exactly one terminal `finish` chunk: `{ kind: 'error', failure }` on failure, `{ kind: 'aborted', failure }` on cancellation. Failures carry stable codes such as `NO_ADAPTER`, `MISSING_CREDENTIAL`, `AUTH`, `RATE_LIMIT`, and `CONTEXT_WINDOW_EXCEEDED`; consumers route on the code, never on message text. A request naming an unregistered provider fails with `NO_ADAPTER`, and a malformed credential fails with `INVALID_CREDENTIAL` instead of surfacing as an opaque fetch error. This service never re-runs a request: retrying is the job of `dsh-llm-retry` at the agent's failed-step extension point.
 
-Message content is an array of typed blocks: `text`, `reasoning`, `image`, `tool-call`, `tool-result`. An `ImageBlock` carries only a durable `ImageAttachmentRef`; provider bytes and request dimensions are resolved later. The union remains merge-extensible through `ContentBlockMap`, so plugins can add further block types via declaration merging. Assistant messages use a model source carrying the provider and model that produced them plus optional adapter-private replay state. Before dispatch, `LlmRuntime` retains that state only when the historical provider route and target provider route are currently owned by the exact same adapter instance; the adapter then decides whether it can restore or convert the state across models/providers.
+-----
 
-Every dispatch uses the exact model modalities captured with its adapter generation. An image-capable adapter projects durable image references into route-specific request versions. `resolveImageAttachmentAccess()` separately combines an attachment provider's optional host object with a consumer-supplied mapping from that host path into the current tool execution world. The result never enters `RequestImageAttachment` or its `variantId`. A text-only route instead receives deterministic attachment placeholders, including nested tool-result images, without changing append-only session history. `offloadRequestImagesWithPolicy()` provides deterministic oldest-first image removal with raw or base64 accounting and count or byte quanta; adapters supply the exact derived-version byte length and the required per-image placeholder text, and the pure `offloadedImagePrefixCount()` exposes the same removal decision so route-owned request pricing reproduces it without building the projection. Adapters whose provider charges visual tokens declare per-route `imageRequestPricing`; `ctx.llm.imageRequestPricing(provider, model)` resolves it synchronously for the token meter.
+<a id="understand-the-implementation"></a>
+## Understand the implementation
 
-Streaming is a raw chunk protocol (`block-start`, `text-delta`, `reasoning-delta`, `tool-call-delta`, `block-end`, `usage`, `finish`). Every adapter outcome reaches consumers as one terminal `finish`; operational failure uses its `error` or `aborted` reason rather than throwing across the stream API. `BlockAssembler` is the single shared implementation that assembles chunks into blocks/messages. A successful `finish` may carry a `ReplayEnvelope` — opaque response-level replay metadata plus optional per-block entries aligned with the emitted block sequence. Assembly makes one keep/drop decision for content and metadata together: a `max-tokens` finish drops tool calls that may have been truncated, and the envelope loses the entry at each dropped position, so stored metadata always describes stored content.

-### Call configuration (`call-config.ts`)
+This section explains the design behind the service; the observable behavior is fully covered in [Use this package](#use-this-package).
 
-`LlmCallConfig` is the provider, model, optional adapter-owned reasoning effort, and sampling scalars of one conversation's requests (`provider`, `model`, `reasoningEffort`, `temperature`, `maxTokens`, `stop` — each mapping 1:1 onto the same-named `GenerateOptions` field). It is per-conversation state recorded in the session log as part of the request header (see the dsh-session `request/header` events), never a silently-adjustable per-call knob: the `agent/request` waterfall proposes a replacement, `prepareCall()` validates it and materializes adapter defaults under the turn signal, and the loop logs the effective value plus markers for fields supplied by adapter defaults before using the prepared call's registration-bound stream. The next proposal omits marked defaults so a changed route resolves its own values; unmarked explicit fields persist. `callConfigEquals(a, b)` is the field-wise real-change detector; `deepFreeze(value)` is the ownership helper the loop applies to every built request before dispatch (`llm/stream` listeners and adapters read, never rewrite). `markAgentLoopRequest()` marks that exact object as created by the process-local agent loop, and `isAgentLoopRequest()` lets observers distinguish it from independently logged auxiliary calls that may also be frozen and session-associated. `GenerateOptions.purpose` classifies logged auxiliary compaction and session-title calls so adapters can apply purpose-specific transport policy without changing ordinary conversation requests.
+### Design philosophy
 
-### App attribution (`attribution.ts`)
+The service is built on one separation: **the logical contract is provider-neutral, adapters own the wire.** It defines the canonical message, content-block, and stream-chunk vocabulary once, and every provider adapter translates only its own wire format into that vocabulary. The registry is the topology owner — adapter routes, configurable-provider entries, and discovery offers all register here and are disposed with their fiber — while a request stays a pure function of the session log: loop-built requests arrive deep-frozen, so listeners and adapters read them and never rewrite them.
 
-Every product adapter sends application identity on provider HTTP requests. `attributionHeaders(identity?)` builds the standard `User-Agent`, defaulting to public `APP_IDENTITY`; white-label deployments may replace but not suppress it. Adapters verify the wire header directly or through their library hook. See [the attribution Agent Note](../../../.agents/notes/implemented/architecture/2026-06-21-mandatory-app-attribution-headers.md).

-Every adapter that puts a credential in an HTTP header judges it the same way before use. `normalizeApiKey(raw)` trims surrounding whitespace, then accepts any non-empty printable-ASCII value (`/^[\x21-\x7E]+$/`, space excluded) or reports why not as an `ApiKeyRejection` (`'empty'` | `'illegalCharacters'`), both carried in the `ApiKeyCheck` result. Absence is never judged: a caller decides whether a value was supplied before asking, since a profile naming no credential authenticates through the provider's own ambient discovery or OAuth.
+### Main flow
 
-### Classes
+A request is validated against its exact model's capability — context window, output default, reasoning efforts, and input modalities — and any adapter-configured defaults are materialized, then the whole request is deep-frozen. `prepareCall()` binds those facts, detached context, and retry policy to the exact adapter generation that performs terminal dispatch, so HMR or dynamic settings cannot combine one generation's image capability with another generation's endpoint. An image-capable adapter projects durable references into route-specific request versions; `resolveImageAttachmentAccess()` separately maps an attachment provider's optional host object into the current tool execution world without changing the request image or its `variantId`. A text-only route receives deterministic per-image placeholders, including nested tool-result images, without rewriting append-only session history. `offloadRequestImagesWithPolicy()` removes oldest images deterministically by raw or base64 size and count or byte quanta; the pure `offloadedImagePrefixCount()` exposes that decision so route-owned request pricing can reproduce it without building the projection. Adapters that charge visual tokens declare per-route `imageRequestPricing`, which `ctx.llm.imageRequestPricing(provider, model)` resolves synchronously for the token meter. Dispatch goes through the `llm/stream` waterfall, then chunks return as token-level deltas and every adapter outcome reaches the consumer as one terminal `finish` chunk.
 
-- `LlmAdapter` — abstract base class for provider adapters. The only required method is `stream()`.
-- `BlockAssembler` — incrementally assembles raw chunks into complete content blocks and can create an identified, frozen assistant message from them. The agent loop feeds it raw chunks (logging them for replay) while reading the assembled blocks for history.
-- `HarnessError` — base class for the harness error taxonomy: a stable `code` string (distinct from the human `message`) plus `cause` chaining. Lives here, in the leaf package every other imports, so a single base is shared without a new dependency edge. Per-package errors (`LlmError`, `ToolArgsError`, `InvariantError`, …) extend it. `isHarnessError(value)` narrows at process boundaries.
-- `LlmError` — extends `HarnessError`; its stable `code` string (`NO_ADAPTER`, `DUPLICATE_ADAPTER`, and adapter codes like `AUTH`/`RATE_LIMIT`) matches its frozen serializable `failure.code`. The payload may also retain validated status, `Retry-After`, and branded provider request id facts; policy remains outside the error.
-- `errorChain(value)` — renders a thrown value with its full `cause` chain and AggregateError members for diagnostic outputs (UI notices, logger lines, durable `turn/end` messages), so transport wrappers like undici's `TypeError: fetch failed` surface the underlying `ECONNREFUSED`/DNS/TLS detail instead of masking it. Rendering only — route on `code`, never by parsing the result.
-- `CONTEXT_WINDOW_EXCEEDED_CODE` — the provider-neutral code both DeepSeek adapters use when a request exceeds the model context window, regardless of thrown-HTTP versus in-band finish delivery. `isContextWindowExceededError(detail)` is their shared conservative classifier for OpenAI-compatible provider detail.
-- `QUOTA_EXCEEDED_CODE` — the non-transient provider-neutral code for exhausted account quota, balance, credits, budget, or usage limits. `isQuotaExceededError(detail)` keeps those failures distinct from request-rate limits.
-- `EMPTY_RESPONSE_CODE` — the provider-neutral code both adapters use for a degenerate provider completion: a terminal `stop` that carried no content blocks at all. Classified as an error finish (not a successful empty message) because the attempt produced nothing durable; `dsh-llm-retry` retries it by default.
-- `INVALID_CREDENTIAL_CODE` — the provider-neutral code for a credential that was supplied but cannot be used: malformed rather than absent, so the fix is to correct the stored value rather than supply one — the distinction from `MISSING_CREDENTIAL`. Deliberately excluded from the default retryable set, since a malformed credential fails identically on every attempt. `assertUsableApiKey(raw, pkg, ref)` throws `LlmError` with this code, the one shared diagnosis every adapter uses for an unusable stored credential.
+### Invariants
 
-### Real adapters
+- **Model-visible ⟺ logged** — anything that reaches a provider request is reconstructable from the session log; loop-built requests are deep-frozen and never rewritten.
+- **Replay state travels only within one adapter** — assistant replay state rides along only when the same adapter instance owns the historical and target routes; otherwise it is dropped before dispatch.
+- **Prepared calls are one-shot** — a prepared call can be dispatched exactly once, and its call-config fields must match the prepared config.
+- **Image projection follows the captured route** — durable `ImageBlock` references become route-specific request versions only for image-capable models; text-only models receive stable placeholders.
+- **Protocol ordering** — `usage` precedes `finish`, tool arguments stay raw JSON strings, and nothing follows the terminal `finish`.
+- **Registry mutations are atomic** — route and directory registration validates the whole candidate set before anything moves, so a refused change leaves the previous state serving.
 
-Two adapters implement `LlmAdapter` on different internals: [`@deepseek-ai/dsh-llm-deepseek`](../llm-deepseek) uses direct fetch with `eventsource-parser` SSE framing for the `deepseek-official` route, while [`@deepseek-ai/dsh-llm-pi-ai`](../llm-pi-ai) dynamically resolves configured provider/model pairs through `@earendil-works/pi-ai`. Both follow the `StreamChunk` conventions in `types.ts`: usage precedes finish and tool arguments remain raw strings. Adapter implementations may throw or emit a failure finish internally; `LlmRuntime` exposes both as a terminal failure finish. See [the twin LLM adapters](../../../.agents/notes/implemented/architecture/2026-06-13-twin-llm-adapters.md) for the adapter rationale and [the terminal-failure decision](../../../.agents/notes/implemented/architecture/2026-07-29-terminal-llm-stream-failures.md) for the service boundary.

 #### KV Cache effect
 
-Reasoning-effort materialization preserves the assembled request prefix. Image identity and request-preview text are deterministic, while the optional execution-world path is resolved for each request. A changed path can alter a historical descriptor and prevent reuse from that image even without offload. Crossing a request limit also replaces an older image with per-image text.

 ## Known Limitations and Deferred Work
 
-- **No retry execution, caching, or rate limiting ships in this service** — provider registration stores retry policy, but `llm/stream` remains a single-attempt call wrapper. The agent loop separately offers proven model-request failures to `agent/request-error`, whose default preserves the original failure; `@deepseek-ai/dsh-llm-retry` is the optional executor loaded by the shared example spine.

-- **Producer-gated variants stay out until produced** — `prefill`, per-tool `strict`, block `cache` hints, and the `agent` message-source variant were pruned as producerless ([Agent Note](../../../.agents/notes/archived/simplification/2026-07-04-prune-producerless-vocabulary-variants.md)).

+`@deepseek-ai/dsh-llm` 是位于 harness LLM 能力核心的提供方无关模型调用服务。任何向模型提供方发起流式请求的组合都会经过它，它拥有 agent loop（智能体循环）、会话日志和所有插件共同使用的共享词汇——消息、内容块与原始流式分片。借助它，你可以注册提供方适配器、流式发起一次模型调用、列出与发现模型、解析精确模型元数据与调用默认值，并捕获每个提供方的重试策略；每个请求都会被记录，因此始终可以从会话日志重建。它不执行重试，也不拥有任何提供方协议逻辑：适配器翻译各自提供方的格式，可选包 `dsh-llm-retry` 在持久步骤边界上重跑失败的请求。请求在分发前会被深度冻结，因此 middleware 与适配器只能读取，绝不能改写。

-每个提供方适配器都会提供解析后的路由策略。省略提供方配置时使用有界 normal mode，在首次请求后最多重试五次。分层配置把 `mode` 改为 `always` 后可能残留 `maxRetries` 或 `retryableCodes`；解析过程会忽略这些不再生效的 normal-mode 字段，并捕获纯 always 策略。本服务存储有效策略，但不执行重试。

+## 使用本包
 
-- `ctx.llm.registerAdapter(providers: string[], adapter: LlmAdapter): AdapterRegistrationHandle` 为给定提供方路由注册一个适配器实例。注册要么全部成功，要么全部不生效，并且会随调用 fiber 一起 dispose（资源释放）。返回的句柄还提供 `replace(providers)`：候选路由集合会在注册状态发生任何变化前完成整体验证，因此与另一适配器发生冲突时，当前路由仍保持注册并继续提供服务。替换会在一次同步操作中完成，不会出现可观察的空档。`replace([])` 合法，表示保留注册但不持有任何路由；初始注册则不得为空。
-- `ctx.llm.listProviders(): LlmProviderInfo[]` 按注册顺序描述已注册提供方路由。
-- `ctx.llm.registerConfigurableProviders(entries: readonly LlmConfigurableProvider[]): DirectoryRegistrationHandle` 声明适配器插件可通过配置激活的提供方路由——无论已注册还是休眠——每个条目指明其所属 settings namespace，以及 profile 在该分节内的路径。要么全部成功，要么全部不生效（`INVALID_DIRECTORY`/`DUPLICATE_DIRECTORY`），并随调用 fiber dispose。该句柄还带 `replace(entries)`：候选集合会先被整体校验，因此其中若有条目已被另一个注册声明，当前集合原封不动；此处允许传空数组。声明集合随配置变化的插件必须使用 `replace`，而不是先 dispose 再重新注册——后者会在新集合被拒时让目录整个落空。
-- `ctx.llm.listConfigurableProviders(): LlmConfigurableProvider[]` 按声明顺序列出可配置提供方目录；配置界面将其与 `listProviders()` 合并，为每个条目标注存活或休眠。条目可携带 `declared`，表示拥有该路由的适配器是否只因配置点名才知道它。只有适配器能回答这一点：该字段缺失时，只表示该适配器不区分这两种来源，不能据此判断路由是否随产品交付。
-- `ctx.llm.registerModelDiscovery(settingsNs: string, discover): () => void` 为本插件拥有的 settings namespace 提供查询提供方端点的能力。每个 namespace 只能有一个（`INVALID_DISCOVERY`/`DUPLICATE_DISCOVERY`），并随调用 fiber dispose。
-- `ctx.llm.listModelDiscoveryNamespaces(): string[]` 列出可以询问端点的 namespace，让界面只在可用之处提供该动作。
-- `ctx.llm.discoverModels(settingsNs: string, request: LlmModelDiscoveryRequest): Promise<LlmDiscoveredModel[]>` 询问某个端点它公布了哪些模型。
-- `ctx.llm.providerRetryPolicy(provider: string): ResolvedRetryPolicy` 返回注册时捕获的提供方自身的重试策略，并解析 normal 默认值。
-- `ctx.llm.listModels(provider: string): Promise<LlmModelInfo[]>` 发现某个已注册提供方当前公布的模型。
-- `ctx.llm.resolveModelInfo(provider: string, model: string, signal?: AbortSignal): Promise<LlmResolvedModelInfo>` 从拥有该精确路由的适配器中，解析并校验确切模型身份，以及可用上下文、输出默认值和推理（reasoning）元数据；异步适配器可选地支持取消。
-- `ctx.llm.resolveCallConfig(config: LlmCallConfig, signal?: AbortSignal): Promise<LlmCallConfig>` 校验显式推理强度，并填入适配器配置的调用默认值，但不自动调整。
-- `ctx.llm.prepareCall(config: LlmCallConfig, signal?: AbortSignal): Promise<PreparedLlmCall>` 在一次精确模型查询中解析配置、脱耦的上下文与模态元数据以及标明哪些字段由适配器默认值填入的标记，再把适配器匹配的分发世代和不可变重试策略捕获为一次可取消、一次性调用。
-- `ctx.llm.stream(options: GenerateOptions): AsyncIterable<StreamChunk>` 将一次模型调用流式输出为原始分片（token 级增量）。消费方使用 `BlockAssembler` 将分片组装为块／消息。
+任何调用模型提供方的组合——agent loop、会话标题生成器、压缩（compaction）摘要器——都会通过本服务流式发起请求。与至少一个提供方适配器一起挂载它；服务本身没有任何配置，也不包含提供方协议代码。
 
-`LlmRuntime` 将最终适配器选择、同步分发、迭代器构造和迭代期间的失败，统一转换为流协议唯一的终止形式：`finish { kind: 'error' | 'aborted', failure }`。部分增量输出后发生失败时，内容块可能仍未闭合；消费方会丢弃这些不完整输出。`llm/stream` middleware、嵌套调用、适配器清理和下游消费方的错误仍会抛出，因为它们属于插件或消费方失败，而非模型请求结果。已准备调用会暴露随其确切适配器注册一同捕获的不可变重试策略；完全由 middleware 处理的路由没有服务策略。
+### 何时选择
 
-询问端点属于配置期针对**草稿**的操作，以 settings namespace 而非提供方路由为键——界面正在新增的提供方还不存在，也就没有路由可点名。但请求仍可**点名**它正在编辑的路由，而已经描述该路由的适配器会用自己的知识作答，无需联网；路由名称和 `baseURL` 至少需要提供一项。除此之外，请求携带端点、协议，以及一条 harness 只用于这一次询问、绝不存储的凭据。这里既不读取也不写入 settings 或 credentials；返回内容是界面可以提供给用户采纳的候选元数据，而不是已注册的 catalog。`LlmDiscoveredModel` 除 `id` 外每个字段都是可选的，因为大多数提供方列表只公布 id；采纳其中一条的界面仍要补上其适配器所需的容量。重复与不可用的 id 会被丢弃，无人服务的 namespace 以 `NO_DISCOVERY` 失败，既不点名路由也不给端点的请求以 `INVALID_DISCOVERY` 失败。
+当插件或组合需要调用模型时选择本包：它是进入提供方适配器的唯一受支持路径，并在 loop、会话日志与每个消费方之间保持同一套词汇。当需要提供方特定的协议行为（那属于 `dsh-llm-deepseek` 或 `dsh-llm-pi-ai` 之类的适配器）或重试执行（那属于 `dsh-llm-retry`）时，不要选择它。
 
-提供方和模型元数据用于发现，不构成路由白名单。`registerAdapter()` 仍拥有提供方路由的排他性，并为每条路由捕获适配器的重试策略；适配器可以接受未出现在 `listModels()` 中的模型 id，消费方不得仅因模型未列出而拒绝请求。返回的 selector 元数据已分离；无效或重复的适配器条目会以 `INVALID_ADAPTER` 或 `INVALID_CATALOG` 失败。
+### 最小组合
 
-每个拓扑提交点——适配器路由注册或 dispose、目录条目出现或撤回——都会在变更之后发出无载荷的 `llm/adapters-updated` 事件，消费方因此会重新读取 `listProviders()`/`listModels()`/`listConfigurableProviders()`，而不是轮询。观察者故障会被记录并隔离，不能否决变更；只有带 `INVARIANT` 码的故障会在通知完所有观察者后重新抛出。
+挂载服务与至少一个适配器，然后在每个请求中按名称选择提供方：
 
-确切模型元数据是独立的正确性查询，不是 catalog 装饰或全局 LLM 设置。`resolveModelInfo()` 会向拥有精确提供方／模型路由的适配器查询一次；适配器可以描述未列出的动态模型。缺少 `context` 表示模型容量未知；缺少 `defaultMaxTokens` 表示继续沿用提供方自身的输出默认值；缺少 `reasoning` 则表示推理能力不可用。无效的身份、上下文、输出默认值或推理元数据会以 `INVALID_MODEL_INFO`、`INVALID_MODEL_CONTEXT`、`INVALID_MODEL_MAX_TOKENS` 或 `INVALID_MODEL_REASONING` 失败。
+```yaml
+- name: '@deepseek-ai/dsh-llm'
+- name: '@deepseek-ai/dsh-llm-deepseek'
+  config:
+    apiKeyEnv: DEEPSEEK_API_KEY
+```
 
-`defaultMaxTokens` 是适配器配置的单次请求输出上限，不是模型硬上限。仅当请求省略 `maxTokens` 时，`resolveCallConfig()` 才会填入该值；显式上限优先。推理标识符是由适配器定义的不透明字符串，而非核心枚举：同一次解析只接受与已公布标识符完全一致的值，在存在 `defaultEffort` 时填入它，否则保留提供方默认值。异步模型解析器会接收调用方信号，并且必须在取消后尽快结算。`prepareCall()` 还会公开脱离内部状态的上下文和输入模态元数据，通过 `adapterDefaults` 标明填入了哪些 `maxTokens` 和 `reasoningEffort` 字段，并把这些事实绑定到执行最终分发的适配器世代。因此，HMR（热模块替换）或动态 settings 不会把一个世代的图片能力与另一个世代的端点组合；复用一次性句柄或更改调用配置字段会以 `INVALID_PREPARED_CALL` 失败。不支持的显式或配置推理强度会在提供方 I/O 前以 `UNSUPPORTED_REASONING_EFFORT` 失败。
+流会返回 token 级分片，并始终以一个终止 `finish` 分片结束；`BlockAssembler` 把分片组装为内容块与消息，loop 记录每个分片以供回放：
 
-### 事件
+```text
+for await (const chunk of ctx.llm.stream({
+  provider: 'deepseek-official',
+  model: 'deepseek-v4-flash',
+  messages: [createUserMessage({ content: [{ type: 'text', text: 'Hello' }] })],
+})) {
+  // chunks: block-start, text-delta, ..., usage, finish
+}
+```
 
-| 事件 | 模式 | 用途 |
-|---|---|---|
-| `llm/stream` | waterfall | 拦截／包装每次流式模型调用，用于缓存、日志或路由 |
+挂载成功后，`ctx.llm.listProviders()` 会按注册顺序报告已注册路由。
 
-### 扩展点
+### 你可以做什么
 
-- 继承 `LlmAdapter` 并调用 `ctx.llm.registerAdapter(providers, adapter)`，添加一条或多条提供方路由。`GenerateOptions.provider` 选择适配器；`GenerateOptions.model` 属于适配器，可以动态解析。覆盖 `providerRetryPolicy()` 以提供由提供方定义的恢复配置，覆盖 `providerInfo()` 和异步 `listModels()` 以公开 selector 元数据；精确身份、容量、输出默认值或可选推理强度可用时，实现 `resolveModel()`；异步解析器必须响应其可选的取消 signal。默认实现使用有界的 normal 重试策略，将路由和模型 id 用作名称，不公布模型，也不返回容量、输出默认值或推理元数据。
-- 包装 `llm/stream` 时，通过 `ctx.on()` waterfall listener 实现缓存、日志或路由。包装层如果在已经发出分片后重试，就没有可持久记录的尝试边界；因此，随产品交付的 agent 重试策略改用 `agent/request-error`。
+- **流式发起一次模型调用**——`ctx.llm.stream(options)` 为任何已注册提供方与模型产出原始分片（token 级增量）；消费方用 `BlockAssembler` 组装。
+- **注册提供方适配器**——一个适配器拥有一个或多个提供方路由，其注册会捕获该路由的重试策略；重复注册同一路由会以 `DUPLICATE_ADAPTER` 失败。
+- **通过配置暴露并激活提供方**——适配器声明可配置提供方路由与 settings namespace，配置界面因此可以激活休眠提供方并编辑连接事实，无需重启。
+- **发现与解析模型**——列出适配器公布的模型、询问端点它提供哪些模型，并解析某个精确模型的上下文窗口、输出默认值、推理（reasoning）强度与输入模态。
+- **校验调用配置**——显式或配置的推理强度会在任何提供方 I/O 之前对照精确模型校验；请求省略输出上限时，会填入适配器配置的输出上限。
 
-### 消息（`message.ts`）与内容块（`types.ts`）
+### 失败与恢复
 
-`Message` 是投递、持久历史和模型请求共享的不可变值。每条消息从创建起都必须具有 `MessageId`、角色、内容和带类型的来源。`createMessage(input)` 生成标识，并返回与输入分离且深度冻结的值；`createUserMessage({ content, source })` 固定 user 角色；`createAssistantMessage({ content, source })` 固定 assistant 角色与模型来源类别；`createToolResultMessage({ callId, content, isError })` 固定 user 角色，并将工具来源与其结果块耦合；`freezeMessage(message)` 导入已有标识，绝不将其替换。改写消息时会保留标识，并产生另一个冻结值。浏览器端代码会从依赖最少的 `@deepseek-ai/dsh-llm/message` 入口导入这些值构造函数，而不是从包含服务的包根入口导入。
+每个流都恰好以一个终止 `finish` 分片结束：失败为 `{ kind: 'error', failure }`，取消为 `{ kind: 'aborted', failure }`。失败携带稳定 code，如 `NO_ADAPTER`、`MISSING_CREDENTIAL`、`AUTH`、`RATE_LIMIT` 与 `CONTEXT_WINDOW_EXCEEDED`；消费方依据 code 路由，绝不解析消息文本。点名未注册提供方的请求会以 `NO_ADAPTER` 失败，格式错误的凭据会以 `INVALID_CREDENTIAL` 失败，而不是表现为不透明的 fetch 错误。本服务从不自行重跑请求：重试是 `dsh-llm-retry` 在 agent 失败步骤扩展点上的职责。
 
-消息内容是类型化内容块数组：`text`、`reasoning`、`image`、`tool-call`、`tool-result`。`ImageBlock` 只携带持久 `ImageAttachmentRef`；提供方字节和请求尺寸之后再解析。联合仍从可合并扩展的 `ContentBlockMap` 派生，因此插件可以通过 declaration merging 添加其他块类型。assistant 消息使用模型来源，其中携带生成该消息的提供方和模型，以及可选的适配器私有回放状态。dispatch 前，`LlmRuntime` 只在历史提供方路由与目标提供方路由当前由完全相同的适配器实例拥有时才保留该状态；随后由适配器判定能否在模型或提供方间恢复或转换该状态。
+-----
 
-每次分发都使用随适配器世代捕获的确切模型模态。支持图片的适配器把持久图片引用投影为路由专用请求版本。`resolveImageAttachmentAccess()` 单独组合附件提供方可选的宿主对象，以及消费方给出的宿主路径到当前工具执行环境的映射。解析结果不进入 `RequestImageAttachment` 或其 `variantId`。纯文本路由则收到确定性的附件占位文本，其中也包括嵌套工具结果图片，追加式会话历史不会改变。`offloadRequestImagesWithPolicy()` 提供确定性的从旧到新图片移除，支持按原始字节或 base64 计数，也支持图片数量或字节量步长；适配器提供确切派生版本的字节长度和必填的逐图占位文本，纯函数 `offloadedImagePrefixCount()` 公开同一移除决策，使路由所属的请求定价无需构建投影即可复现它。提供方对图片收取视觉 token 的适配器声明按路由的 `imageRequestPricing`；`ctx.llm.imageRequestPricing(provider, model)` 为 token 计量服务同步解析它。
+<a id="understand-the-implementation"></a>
+## 理解实现
 
-流式输出是原始分片协议（`block-start`、`text-delta`、`reasoning-delta`、`tool-call-delta`、`block-end`、`usage`、`finish`）。每个适配器结果都以一个终止 `finish` 到达消费方；运行故障使用 `error` 或 `aborted` 作为结束原因，而不会跨流 API 抛出。`BlockAssembler` 是将分片组装为块／消息的唯一共享实现。成功的 `finish` 可以携带 `ReplayEnvelope`——不透明的响应级回放元数据，加上与发射块序列对齐的可选逐块条目。组装对内容与元数据只做一次保留/丢弃决定：`max-tokens` 结束会丢弃可能被截断的工具调用，数据在每个被丢弃的位置同步失去对应条目，因此存储的元数据始终描述存储的内容。

+<summary>实现细节——点击展开</summary>
 
-### 调用配置（`call-config.ts`）
+本节解释服务背后的设计；可观察行为已在[使用本包](#use-this-package)中完整说明。
 
-`LlmCallConfig` 记录一个会话的模型请求所使用的提供方、模型、由适配器定义的可选推理强度，以及采样参数（`provider`、`model`、`reasoningEffort`、`temperature`、`maxTokens`、`stop`，分别与同名 `GenerateOptions` 字段一一对应）。它是作为请求标头一部分记录在会话日志中的每会话状态（见 dsh-session `request/header` 事件），绝不是可静默调整的每次调用旋钮：`agent/request` waterfall 会提议替换，`prepareCall()` 在轮次 signal 控制下校验它并填入适配器默认值，loop 随后记录生效值以及标明哪些字段由适配器默认值填入的标记，再使用已准备调用中与注册绑定的流。下一次提议会省略带标记的默认值，使变更后的路由解析自身的值；未带标记的显式字段会保留。`callConfigEquals(a, b)` 是逐字段真实变更检测器；`deepFreeze(value)` 是 loop 使用的请求所有权辅助函数：每个构造完成的请求都会在分发前深度冻结；`llm/stream` 监听器和适配器只能读取，绝不能改写。`markAgentLoopRequest()` 将该精确对象标记为由进程本地 agent loop 创建，`isAgentLoopRequest()` 让观测方可以将其与同样可能冻结并关联会话、但独立记录的辅助调用区分。`GenerateOptions.purpose` 会对已记录的辅助压缩和会话标题调用进行分类，使适配器可以按调用目的应用不同的传输策略，而不改变普通会话请求。
+### 设计理念
 
-<a id="app-attribution-attributionts"></a>
+服务建立在一个分离之上：**逻辑约定是提供方无关的，适配器拥有协议。** 它一次性地定义规范消息、内容块与流式分片词汇，每个提供方适配器只把自己的协议格式翻译为该词汇。注册表是拓扑的拥有者——适配器路由、可配置提供方条目与发现 offer 都在这里注册，并随其 fiber 一起 dispose（资源释放）——而请求始终是会话日志的纯函数：loop 构建的请求以深度冻结状态到达，因此监听器与适配器只能读取，绝不能改写。
 
-### 应用归因（`attribution.ts`）
+### 源码地图
 
-每个产品适配器都会在提供方 HTTP 请求上发送应用身份。`attributionHeaders(identity?)` 构建标准 `User-Agent`，默认为公开 `APP_IDENTITY`；白标部署可以替换它，但不能抑制它。适配器会直接验证 wire 标头，或通过自身库 hook 验证。详见 [归因 Agent Note](../../../.agents/notes/implemented/architecture/2026-06-21-mandatory-app-attribution-headers.zh.md)。

-### API 密钥校验（`api-key.ts`）
+### 主流程
 
-每个要把凭据放进 HTTP 标头的适配器，使用前都以同一套规则校验它。`normalizeApiKey(raw)` 会先去除首尾空白，然后接受任意非空的可打印 ASCII 值（`/^[\x21-\x7E]+$/`，不含空格），或通过 `ApiKeyRejection`（`'empty'` | `'illegalCharacters'`）说明拒绝原因。这些结果一并包含在 `ApiKeyCheck` 中。缺失从不参与校验：调用方会在询问之前自行判断是否提供了值——未点名凭据的 profile 会转由提供方自身的环境发现或 OAuth 完成认证。
+请求会对照其精确模型的能力——上下文窗口、输出默认值、推理强度与输入模态——校验，填入任何适配器配置的默认值，然后整个请求被深度冻结。`prepareCall()` 把这些事实、分离的上下文与重试策略绑定到执行最终分发的精确适配器代次，因此 HMR 或动态设置无法把一个代次的图片能力与另一代次的端点混用。支持图片的适配器把持久引用投影为路由专用请求版本；`resolveImageAttachmentAccess()` 会单独把附件提供方的可选宿主对象映射进当前工具执行世界，而不改变请求图片或其 `variantId`。纯文本路由接收确定性的逐图片占位符，包括嵌套工具结果图片，而不会改写仅追加会话历史。`offloadRequestImagesWithPolicy()` 按原始字节或 base64 大小以及图片数或字节步长，确定性地从最旧图片开始移除；纯函数 `offloadedImagePrefixCount()` 公开同一决策，使路由所属的请求定价无需构建投影即可复现它。对视觉 token 收费的适配器声明按路由的 `imageRequestPricing`，`ctx.llm.imageRequestPricing(provider, model)` 为 token meter 同步解析它。分发经过 `llm/stream` waterfall，随后分片以 token 级增量返回，每个适配器结果都以唯一一个终止 `finish` 分片到达消费方。
 
-### 类
+### 不变式
 
-- `LlmAdapter`：提供方适配器的抽象基类。唯一必需方法是 `stream()`。
-- `BlockAssembler`：将原始分片逐步组装为完整内容块，并能据此创建带标识且冻结的 assistant 消息。agent loop 向它提供原始分片（同时记录以供回放），并读取已组装块以构建历史。
-- `HarnessError`：harness 错误分类体系的基类，包含稳定 `code` 字符串（与面向人的 `message` 不同）以及 `cause` 链。它位于所有其他包都从中导入的叶子包中，因此可以共享单一基类，无需新的依赖边。各包的错误（`LlmError`、`ToolArgsError`、`InvariantError` 等）都继承自它。`isHarnessError(value)` 在进程边界处收窄类型。
-- `LlmError`：继承自 `HarnessError`；其稳定 `code` 字符串（`NO_ADAPTER`、`DUPLICATE_ADAPTER` 与 `AUTH`／`RATE_LIMIT` 等适配器 code）与冻结可序列化 `failure.code` 匹配。Payload 还可以保留已验证状态、`Retry-After` 和品牌化提供方请求 id 事实；策略位于错误之外。
-- `errorChain(value)`：渲染抛出值的完整 `cause` 链与 AggregateError 成员，供诊断输出使用，包括 UI 通知、logger 行和持久 `turn/end` 消息。因此 undici 的 `TypeError: fetch failed` 等传输包装层会显示底层 `ECONNREFUSED`／DNS／TLS 详细信息，而不是将其遮蔽。该函数只负责生成诊断文本。调用方必须依据稳定的 `code` 选择错误处理路径，绝不能通过解析渲染后的文本作出判断。
-- `CONTEXT_WINDOW_EXCEEDED_CODE`：当请求超过模型上下文窗口时，无论通过 HTTP 异常抛出还是带内 finish 交付，两个 DeepSeek 适配器都使用的提供方无关 code。`isContextWindowExceededError(detail)` 是它们针对 OpenAI 兼容提供方详细信息的共享保守分类器。
-- `QUOTA_EXCEEDED_CODE`：帐户配额、余额、点数、预算或用量限制耗尽时使用的非暂时性提供方无关 code。`isQuotaExceededError(detail)` 使这些失败与请求速率限制保持区分。
-- `EMPTY_RESPONSE_CODE`：两个适配器都使用的提供方无关 code，用于表示退化的提供方生成结果：一个未携带任何内容块的终止 `stop`。它会被分类为错误 finish（而非成功空消息），因为尝试未产生持久内容；`dsh-llm-retry` 默认重试它。
-- `INVALID_CREDENTIAL_CODE`：已提供但无法使用的凭据所用的提供方无关 code——格式错误而非缺失，修复方式是改正已存储的值，而不是补充一个凭据，这正是它与 `MISSING_CREDENTIAL` 的区别。它被刻意排除在默认可重试集合之外：格式错误的凭据每次尝试都会以同样方式失败。`assertUsableApiKey(raw, pkg, ref)` 会以该 code 抛出 `LlmError`，是每个适配器判定已存储凭据不可用时共用的诊断。
+- **模型可见 ⟺ 已记录**——到达提供方请求的任何内容都可以从会话日志重建；loop 构建的请求被深度冻结，绝不改写。
+- **回放状态只在同一适配器内流动**——仅当同一适配器实例同时拥有历史路由与目标路由时，assistant 回放状态才会随行；否则在分发前被丢弃。
+- **已准备调用是一次性的**——已准备调用只能分发一次，且其调用配置字段必须与准备好的配置一致。
+- **图片投影遵循捕获的路由**——只有支持图片的模型会把持久 `ImageBlock` 引用转换为路由专用请求版本；纯文本模型接收稳定占位符。
+- **协议顺序**——`usage` 先于 `finish`，工具参数保持原始 JSON 字符串，终止 `finish` 之后不再有任何内容。
+- **注册表变更具有原子性**——路由与目录注册会在任何变动前整体校验候选集合，因此被拒绝的变更会让此前状态继续服务。
 
-### 真实适配器
+</details>
 
-两个适配器使用不同内部机制实现 `LlmAdapter`：[`@deepseek-ai/dsh-llm-deepseek`](../llm-deepseek) 针对 `deepseek-official` 路由使用直接 fetch 加 `eventsource-parser` SSE（Server-Sent Events）分帧，[`@deepseek-ai/dsh-llm-pi-ai`](../llm-pi-ai) 则通过 `@earendil-works/pi-ai` 动态解析已配置提供方／模型对。两者都遵循 `types.ts` 中的 `StreamChunk` 约定：usage 先于 finish，工具参数保持原始字符串。适配器实现在内部可以抛出异常或发出失败 finish；`LlmRuntime` 会将两者都暴露为终止失败 finish。适配器理由见[双 LLM 适配器](../../../.agents/notes/implemented/architecture/2026-06-13-twin-llm-adapters.zh.md)，服务边界见[终止失败决策](../../../.agents/notes/implemented/architecture/2026-07-29-terminal-llm-stream-failures.zh.md)。

 ## 模型体验
 
-无。适配器决定何时加入该包导出的共用图片描述和逐图占位文本，LLM 服务本身只会填入并记录适配器配置的请求事实。
+没有直接影响，因为 LLM 服务不添加内容；适配器决定何时添加本包导出的共享图片描述符与逐图片占位符。
 
 #### KV Cache 影响
 
-推理强度填入不会改变已组装的请求前缀。图片身份和请求预览文本具有确定性，可选的执行环境路径则按请求解析。路径变化会改写历史图片描述，即使没有 offload，也可能使缓存从该图片起无法复用。请求越过上限时，较旧图片也会替换为逐图文本。
+推理强度的具体化会保留已组装请求前缀。图片身份与请求预览文本是确定性的，可选执行世界路径则按请求解析；路径变化或图片卸载边界变化可能从该图片起阻止复用。

+## 已知限制与延期工作
 
 <a id="known-limitations-and-deferred-work"></a>
 
-## 已知限制与暂缓事项

-Replay-aware token measurement through the singleton `ctx.tokenMeter` service. It advances one isolated fold per session from the durable log, so compaction and other pressure-sensitive plugins can share accounting without depending on `CompactionEngine`.
+## Summary
 
-## Configuration
+`@deepseek-ai/dsh-token-meter` is the replay-aware token measurement service: `ctx.tokenMeter` advances one isolated fold per session from the durable event log, so compaction and other pressure-sensitive plugins share one accounting without depending on the compaction engine. With it you can measure current request and context pressure, price a single message, and — when the session-projection seam is mounted — read the `tokenUsage`, `contextPressure`, and `contextBreakdown` projections. It uses a fixed heuristic for text and routes without image pricing, applies adapter-declared visual-token pricing when available, and reuses provider-reported usage only when the request envelope matches exactly. It adds no prompt, message, schema, or tool of its own, and it never makes decisions for the loop.
 
-The estimator has no settings. It intentionally uses one fixed heuristic: four characters per token plus structural overhead for roles, blocks, and request-envelope fields. Any key is rejected; model capacity belongs to the adapter that owns an exact provider/model route and is available through `ctx.llm.resolveModelInfo().context`.

-`ctx.tokenMeter` directly exposes two operations:
+-----
 
-- `measure(session, requestHeader?)` returns request pressure and the current priced surface at one consumed-log revision.
-- `estimateMessage(message)` prices one message with the fixed heuristic.
+<a id="use-this-package"></a>
+## Use this package
 
-`measure()` synchronizes once and returns one detached, deeply immutable snapshot. `totalTokens` is request-and-response pressure, while `surfaceTokens` is the surface-only route-priced total and equals the sum of `nodes[].tokens`. A `requestHeader` override selects the priced route and the pressure fields; the node set still describes the current session. Every call clones the positional nodes, so measurement is O(surface).
+Mount this plugin when a consumer needs token or context pressure for compaction decisions, occupancy displays, or telemetry. The estimator has no settings and adds no model-visible surface; model capacity belongs to the adapter that owns the exact provider/model route and is available through `ctx.llm.resolveModelInfo().context`.
 
-The fold tracks full request-header snapshots, step boundaries, surface appends and replacements, successful assistant messages, provider usage, and the chunk seqs cited by each assistant message. Each measurement resolves the effective envelope's provider/model to that route's declared request-image pricing through the optional `llm` service: image occurrences are then priced as the visual tokens plus model-visible text the routed request actually sends, while routes and compositions without declared pricing keep the fixed heuristic. Every node also carries `heuristicTokens`, the route-independent fixed price the shadow-price protocol uses for replacements. Provider usage is reused only when the latest successful call's canonical request envelope matches the measured envelope and its total is no lower than that call's full route-priced anchor; a later success replaces the earlier anchor. Otherwise the complete current envelope and surface are estimated. Surface changes remain signed relative to a matching anchor repriced under the same route, including negative deltas after shrinking replacements.
+### When to choose it
 
-Usage accounting sums disjoint input, cache-read, cache-write, and output buckets; reasoning is not added again. Every successful call records an assistant anchor, including content-less calls. An explicit empty `sourceEventSeqs` list means a known empty provider stream, while an absent legacy list conservatively treats the durable assistant output as provider output.
+Choose it when several plugins should agree on one replay-based measurement — compaction planning, occupancy UIs, and pressure checks all read the same fold. The measurements replay the durable session log, so they are deterministic, cost no model calls, and reflect exactly what is logged. Text and undeclared image routes use a fixed heuristic; reach for a provider tokenizer when a deployment needs exact billing-grade counts.
 
-## Session projections
+### Measuring pressure
 
-When the composition provides `ctx.sessionProjections`, token-meter registers three units through an optional child fiber.
+`ctx.tokenMeter` exposes two operations. `measure(session, requestHeader?)` returns a detached, deeply immutable snapshot at one consumed-log revision: `totalTokens` is request-and-response pressure, and `surfaceTokens` is the surface-only route-priced total equal to the sum of `nodes[].tokens`. An optional `requestHeader` override selects the priced route and pressure fields; the node set still describes the current session. `estimateMessage(message)` prices one message with the fixed heuristic. Every call clones the positional surface nodes, so measurement is O(surface).
 
-`tokenUsage` carries the complete durable log's `uncachedInputTokens`, `outputTokens`, `cacheReadTokens`, and `cacheWriteTokens`. Usage chunks are counted even when a request later fails; a final assistant-message usage replaces the streaming sample from the same model attempt instead of double-counting it. A matching `llm/retry-started` boundary ends that replacement scope, so a retry with the same `(turn, step)` contributes a new billed attempt. Reasoning remains an output subdivision. The single last-sample slot relies on a session-log ordering property: once a later step reports usage, a legal log never reports usage for an earlier step again.
+```text
+const { totalTokens, surfaceTokens, nodes } = ctx.tokenMeter.measure(session)
+const price = ctx.tokenMeter.estimateMessage(message)
+```
 
-Token-meter also owns the browser-safe pure fold from one complete Turn's durable events to exact attempt and Turn usage. `step/start` and `llm/retry-started` open real attempts; final message usage replaces that attempt's streaming sample; terminal failures, retries, and step boundaries close it. Missing lifecycle evidence, unsafe counts, or contradictory exact totals fail closed. Presentation consumers select a complete Turn window and render the result; they do not define a second accounting state machine.
+Each measurement resolves the effective envelope's provider/model through the optional `llm` service. Image occurrences use the routed request's visual-token price plus model-visible text when the adapter declares pricing; other routes keep the fixed heuristic. Each node also carries route-independent `heuristicTokens` for replacement shadow prices. Provider usage is reused only when the latest successful call's canonical request envelope matches the measured envelope and its total is no lower than that call's full route-priced anchor; otherwise the complete current envelope and surface are estimated. Surface changes stay signed relative to a matching anchor repriced under the same route, including negative deltas after shrinking replacements.
 
-`contextPressure` carries optional `pressureTokens` — the newest provider-reported prompt size, summing uncached input plus cache reads and writes — optional `projectedTokens`, and optional `contextWindow` from the newest `request/context` record. Both figures stay absent until a provider reports usage; capacity stays absent for a route whose adapter advertises none. Output is excluded, so `pressureTokens` holds still while a turn streams and steps forward when the next request reports its usage.
+### Session projections
 
-`projectedTokens` is what the NEXT request's prompt would cost: the sample plus the heuristic repricing of everything the surface gained or lost since it was taken, clamped at zero. Its O(1) fold in `surface-projection.ts` tracks appends and consumes the logged shadow price immediately before a replacement; on fully metered logs it agrees with the measurement service's positional plan/commit fold without retaining per-node prices. Only the delta is estimated, so the figure stays anchored to the provider while reacting the moment content lands — or a compaction shadows a span. That last case is why the field exists: compaction summarizes through a direct `ctx.llm.stream()` call and appends no usage of its own, so `pressureTokens` alone reports the pre-compaction prompt until an entire further turn completes. Occupancy displays read `projectedTokens`.
+When the composition provides `ctx.sessionProjections`, token-meter registers three projection units. `tokenUsage` carries the complete durable log's `uncachedInputTokens`, `outputTokens`, `cacheReadTokens`, and `cacheWriteTokens`. A final assistant-message sample replaces streaming usage from the same attempt; `llm/retry-started` ends that replacement scope, so a retry in the same step contributes another billed attempt. `contextPressure` carries optional `pressureTokens` (the newest provider-reported prompt size), optional `projectedTokens` (what the next request's prompt would cost), and optional `contextWindow` from the newest `request/context` record. `contextBreakdown` carries heuristic `systemTokens`, `toolsTokens`, and `messageTokens` — the context's composition, not its provider-billed size. Unloading the plugin removes all three keys.
 
 `contextBreakdown` carries heuristic `systemTokens`, `toolsTokens`, and `messageTokens` — the context's composition rather than its provider-billed size. The envelope figures reprice last-wins on every `request/header`; the message figure replays the same O(1) shadow-price fold as `contextPressure`, so on fully metered logs it equals the sum of `measure().nodes[].heuristicTokens` at every event boundary and compaction shrinks it by its logged shadow price. The route-priced `measure().surfaceTokens` diverges when the routed model reprices images. A replacement without an adjacent shadow-price claim leaves this bounded projection unchanged because it cannot reconstruct the replaced range. All three figures use the measurement service's fixed heuristic and are estimates: they will not sum to `projectedTokens`, whose provider anchor carries exactly the error — CJK text and JSON schemas underprice badly at four characters per token — that the composition rows still contain. Present them as an approximate composition, never as a total.
 
-All three units use the standard projection baseline, live frame, higher-seq-wins store, and JSON checkpoint paths. Unloading token-meter removes all three keys. A composition without the projection seam keeps the measurement service's existing behavior.
+`deriveTurnTokenUsage(events)` folds one complete Turn into exact per-attempt and total usage for browser consumers. Missing lifecycle evidence, unsafe counts, or contradictory exact totals return no result; optional cache, reasoning, and route aggregates appear only when every contributing attempt reports them.
 
-### Context occupancy is an approximation, by design
-
-The occupancy fields are independent last-wins records and are **not** one atomic observation of a single request. Switching models pairs the fresh capacity with the previous route's sample until the next request reports usage, and `pressureTokens` describes the last request rather than the surface as it stands right now — `projectedTokens` carries that sample forward over the surface's movement, but its anchor is still the older request.
-
-This is deliberate. An occupancy percentage is a user-facing reference figure, not a billing record or a gating input — nothing in the harness makes decisions from it, and compaction reads `measure()` instead. A UI computes occupancy by dividing measured pressure by the separately resolved capacity for the selected model.
-
-The [Agent Note](../../../.agents/notes/implemented/architecture/2026-07-29-projected-token-usage-and-request-context.md) records the rejected atomic-pair comparison. Consumers that need an exact same-boundary figure should call `measure()` at their own request boundary rather than read this projection.

+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design behind the service; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The service is built on one fold and one anchor. Each session gets an isolated replay state — consumed-event cursor, canonical request header, priced surface, step boundary, and measurement anchor — advanced by folding the durable log. Provider usage anchors a measurement only when its canonical envelope matches and its total is no lower than the full route-priced cost of the same call; otherwise the complete envelope and surface are estimated. The route-independent `heuristicTokens` field keeps replacement shadow-price projections deterministic. The fold is total and allocation-fresh: a malformed event throws before any mutation, so the same log fails identically on every retry.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | The `TokenMeter` service: replay state, fold, `measure()` and `estimateMessage()` |
+| [`src/estimate.ts`](src/estimate.ts) | The fixed heuristic: four characters per token plus block and role overhead |
+| [`src/surface-fold.ts`](src/surface-fold.ts) | The positional surface fold shared with `measure()` |
+| [`src/surface-projection.ts`](src/surface-projection.ts) | Shadow-price protocol for the O(1) projection units |

+| [`src/breakdown-projection.ts`](src/breakdown-projection.ts) | `contextBreakdown` projection definition |
+| [`src/client.ts`](src/client.ts) | Browser-safe client surface for projection consumers |
+| [`src/turn-usage.ts`](src/turn-usage.ts) | Pure fold for exact per-attempt and per-Turn usage |
+
+### Fold flow
+
+Each `measure()` call synchronizes the fold to the current durable tail, then reads one coherent snapshot. The fold tracks full request-header snapshots, step boundaries, surface appends and replacements, successful assistant messages, provider usage, and the chunk seqs each assistant message cites. Provider output for a usage anchor is reassembled from the exact cited chunk seqs; an explicit empty list means a known empty provider stream, while a missing legacy list conservatively treats the durable assistant output as provider output.
+
+### Projection semantics
+
+The projection units do not share the full surface fold because their persisted state must stay O(1). `surface-projection.ts` prices appends and consumes the shadow price logged immediately before a replacement; it keeps one running total and at most one pending claim, not per-node prices. Fully metered logs therefore match `measure()`'s plan/commit fold at each event boundary. A replacement without an adjacent matching claim leaves the bounded projection unchanged because it cannot reconstruct the replaced range. The single last-usage-sample slot relies on a session-log ordering property: once a later step reports usage, a legal log never reports usage for an earlier step again.

+These limits define where the measurement stops and future work begins. They are current package constraints, not a general token-accounting comparison or a task backlog.

 - **The fixed heuristic is approximate** — text without reusable provider usage is priced by character count plus structural overhead, not an exact provider tokenizer or request serializer; only image occurrences on routes with declared pricing carry provider-exact visual tokens.
 - **Every measurement clones the current surface** — coherent immutable snapshots make reads O(surface), including below-threshold pressure checks.
 - **Provider usage is only reusable for an identical canonical envelope** — prompt, prefix, tools, provider, model, or call-config changes deliberately fall back to full heuristic estimation.
 - **Missing legacy source seqs are handled conservatively** — assistant messages without `sourceEventSeqs` cannot distinguish provider output from listener rewrites, so the fold avoids claiming a known empty or exact chunk stream.

 # @deepseek-ai/dsh-token-meter
 
 [English](README.md) | 中文
 
-通过单例 `ctx.tokenMeter` 服务进行具备回放感知能力的 token 测量。它从持久日志为每个会话推进一个隔离 fold，因此压缩（compaction）与其他压力敏感插件可以共享计量，无需依赖 `CompactionEngine`。
+## 概述
 
-## 配置
+`@deepseek-ai/dsh-token-meter` 是具备回放感知的 token 计量服务：`ctx.tokenMeter` 从持久事件日志为每个会话推进一个隔离 fold，因此压缩（compaction）与其他压力敏感插件可以共享同一份计量，无需依赖压缩引擎。借助它，你可以测量当前请求与上下文压力、为单条消息计价，并且在挂载会话投影 seam 时读取 `tokenUsage`、`contextPressure` 与 `contextBreakdown` 投影。文本和未声明图片定价的路由使用固定启发式规则，存在时则应用适配器声明的视觉 token 定价；只有请求 envelope 完全匹配时才复用提供方报告的用量。它不添加任何自己的提示词、消息、schema 或工具，也绝不为 loop 做决定。
 
-估算器没有配置项。它有意使用一项固定启发式规则：每个 token 按四个字符估算，再加上角色、块与请求 envelope 字段的结构开销。任何配置键都会被拒绝；模型容量属于拥有精确提供方／模型路由的适配器，可通过 `ctx.llm.resolveModelInfo().context` 获取。

-`ctx.tokenMeter` 直接公开两个操作：
+-----
 
-- `measure(session, requestHeader?)` 在同一个已消费日志 revision 上返回请求压力与当前已计价表层。
-- `estimateMessage(message)` 使用固定启发式规则为一条消息计价。
+<a id="use-this-package"></a>
+## 使用本包
 
-`measure()` 会同步一次，并返回一个独立且深度不可变的快照。`totalTokens` 是请求与响应压力，`surfaceTokens` 是表层的路由定价总量，等于 `nodes[].tokens` 之和。`requestHeader` 覆盖会选择计价路由并影响压力字段；节点集合仍描述当前会话。每次调用都会克隆带位置的节点，因此测量是 O(surface)。
+当消费方需要为压缩决策、占用显示或遥测获取 token 或上下文压力时挂载本插件。估算器没有任何配置，也不添加模型可见表面；模型容量属于拥有精确提供方／模型路由的适配器，可通过 `ctx.llm.resolveModelInfo().context` 获取。
 
-fold 跟踪完整请求标头快照、步骤边界、表层追加与替换、成功 assistant 消息、提供方用量，以及每条 assistant 消息引用的分片 seq。每次计量都会通过可选的 `llm` 服务把生效 envelope 的 provider/model 解析为该路由声明的请求图片定价：图片出现处按路由请求实际发送的视觉 token 加模型可见文本计价，未声明定价的路由与组合保持固定启发式规则。每个节点还携带与路由无关的固定价格 `heuristicTokens`，供影子价协议为替换计价。只有当最新成功调用的规范请求 envelope 与已测量 envelope 匹配，且其总量不低于该调用的完整路由定价锚点时，才会复用提供方用量；后续成功会替换较早锚点。否则会对当前 envelope 与表层进行完整估算。表层变更保持相对于匹配锚点（按同一路由重新定价）的带符号值，包括缩减替换后的负 delta。
+### 何时选择
 
-用量计量会求和不重叠的输入、cache-read、cache-write 与输出 bucket；不会再次添加推理（reasoning）。每次成功调用都会记录一个 assistant 锚点，包括无内容调用。显式的空 `sourceEventSeqs` 列表表示已知空提供方流；遗留记录缺少该列表时，fold 会保守地将持久 assistant 输出视为提供方输出。
+当多个插件应该就同一种基于回放的测量达成一致时选择它——压缩规划、占用 UI 与压力检查都读取同一个 fold。测量回放持久会话日志，因此确定、无需模型调用，并精确反映已记录内容。文本和未声明图片定价的路由使用固定启发式规则；当部署需要精确到计费级别的计数时，使用提供方分词器。
 
-## 会话投影
+### 测量压力
 
-当组合提供 `ctx.sessionProjections` 时，token-meter 会通过一个可选子 fiber 注册三个单元。
+`ctx.tokenMeter` 暴露两个操作。`measure(session, requestHeader?)` 在同一个已消费日志 revision 上返回独立、深度不可变的快照：`totalTokens` 是请求与响应压力，`surfaceTokens` 是仅表面的路由定价总量，等于 `nodes[].tokens` 之和。可选 `requestHeader` 覆盖会选择计价路由与压力字段；节点集合仍描述当前会话。`estimateMessage(message)` 用固定启发式规则为一条消息计价。每次调用都会克隆带位置的表面节点，因此测量是 O(surface)。
 
-`tokenUsage` 携带完整持久日志中的 `uncachedInputTokens`、`outputTokens`、`cacheReadTokens` 和 `cacheWriteTokens`。即使请求随后失败，用量分片仍会计入；最终 assistant 消息用量会替换同一次模型 attempt 的流式样本，而不是重复计数。匹配的 `llm/retry-started` 边界会结束该替换作用域，因此复用同一 `(turn, step)` 的重试会贡献一次新的计费 attempt。推理仍是输出的一个细分项。只保留单个最新样本，依赖的是会话日志的一条顺序性质：一旦某个更晚的步骤报告了用量，合法日志就绝不会再为更早的步骤报告用量。
+```text
+const { totalTokens, surfaceTokens, nodes } = ctx.tokenMeter.measure(session)
+const price = ctx.tokenMeter.estimateMessage(message)
+```
 
-token-meter 还拥有一份可安全用于浏览器的纯 fold，将一个完整 Turn 的持久事件归并为精确的 attempt 与 Turn 用量。`step/start` 与 `llm/retry-started` 打开真实 attempt；最终消息用量替换该 attempt 的流式样本；终止失败、重试与步骤边界关闭它。缺少生命周期证据、计数不安全或精确总量矛盾时一律 fail-closed。展示消费方只选择完整 Turn 窗口并渲染结果，不再定义第二套记账状态机。
+每次测量都会通过可选的 `llm` 服务解析生效 envelope 的提供方／模型。适配器声明图片定价时，图片出现处使用路由请求的视觉 token 价格加模型可见文本；其他路由保持固定启发式规则。每个节点还携带与路由无关的 `heuristicTokens`，供替换影子价使用。只有当最新成功调用的规范请求 envelope 与已测量 envelope 匹配、且其总量不低于该调用完整路由定价锚点时，才复用提供方用量；否则会对完整当前 envelope 与表面做估算。表面变更保持相对于按同一路由重新定价的匹配锚点的带符号值，包括缩减替换后的负 delta。
 
-`contextPressure` 携带可选的 `pressureTokens`（提供方报告的最新提示词规模，为未缓存输入加缓存读取与写入之和）、可选的 `projectedTokens`，以及来自最新一条 `request/context` 记录的可选 `contextWindow`。提供方报告用量前两个数字都保持缺失；路由适配器未公布容量时容量也保持缺失。输出不计入其中，因此轮次流式输出期间 `pressureTokens` 保持不动，等到下一个请求报告用量时才前进。
+### 会话投影
 
-`projectedTokens` 是「下一个请求的提示词要花多少」：在该样本之上，加上自取样以来表层增减部分的启发式重新计价，并将下界钳制为零。它在 `surface-projection.ts` 中的 O(1) 折叠会跟踪追加，并消费紧邻替换之前记录的影子价；在完整计量的日志上，它无需保留逐节点价格也能与测量服务的带位置 plan/commit 折叠一致。只有增量部分是估算的，因此这个数字既锚定在提供方读数上，又能在内容落地——或压缩遮蔽一段区间——的瞬间做出反应。最后这种情况正是该字段存在的理由：压缩通过直连的 `ctx.llm.stream()` 调用生成摘要，自身不追加任何用量，所以仅凭 `pressureTokens` 会一直报告压缩前的提示词规模，直到再完成一整个轮次为止。占用率展示读取 `projectedTokens`。
+当组合提供 `ctx.sessionProjections` 时，token-meter 注册三个投影单元。`tokenUsage` 携带完整持久日志中的 `uncachedInputTokens`、`outputTokens`、`cacheReadTokens` 与 `cacheWriteTokens`。最终 assistant 消息样本会替换同一次尝试的流式用量；`llm/retry-started` 会结束该替换范围，因此同一步骤中的重试会贡献另一次计费用量。`contextPressure` 携带可选 `pressureTokens`（提供方报告的最新提示词规模）、可选 `projectedTokens`（下一个请求的提示词将花费多少）与来自最新一条 `request/context` 记录的可选 `contextWindow`。`contextBreakdown` 携带启发式 `systemTokens`、`toolsTokens` 与 `messageTokens`——上下文的构成，而非提供方计费规模。卸载插件会移除全部三个键。
 
 `contextBreakdown` 携带启发式的 `systemTokens`、`toolsTokens` 与 `messageTokens`，描述上下文的组成而非提供方计费规模。envelope 数字在每条 `request/header` 上按后者胜重新计价；消息数字重放与 `contextPressure` 相同的 O(1) 影子价折叠，因此在完整计量的日志上，它在每个事件边界都等于 `measure().nodes[].heuristicTokens` 之和，压缩会按记录的影子价缩小该值。路由定价的 `measure().surfaceTokens` 在路由模型重新为图片计价时会与该值不同。若替换前没有紧邻的影子价声明，这个有界投影会保持不变，因为它无法重建被替换区间。三个数字都使用测量服务的固定启发式规则，属于估算值。它们加起来不等于 `projectedTokens`，后者的提供方锚点体现了这些明细行仍然带有的误差（按「4 字符 ≈ 1 token」计价时，CJK 文本与 JSON schema 会被严重低估）。请把它们当作近似的**组成**呈现，而不是总量。
 
-三个单元都使用标准的投影基线、实时帧、seq 高者胜值仓和 JSON 检查点路径。卸载 token-meter 会移除这三个键。不带投影 seam 的组合会保留测量服务的既有行为。
+`deriveTurnTokenUsage(events)` 为浏览器消费方把一个完整 Turn 折叠为精确的逐次尝试与整轮用量。生命周期证据缺失、计数不安全或精确总量矛盾时不返回结果；只有每次参与的尝试都报告可选缓存、推理或路由值时，相应汇总才会出现。
 
-### 上下文占用率是刻意为之的近似值
-
-这些占用率字段各自后者胜、彼此独立，**不是**对单个请求的一次原子观测。切换模型时，新容量会与上一路由的样本配对，直到下一个请求报告用量为止；而 `pressureTokens` 描述的是最后一个请求，不是此刻的表层——`projectedTokens` 把该样本沿表层的增减推进到当下，但它的锚点仍然是那个较早的请求。
-
-这是刻意的选择。占用率百分比是面向用户的参考数字，既不是计费记录，也不是门控输入：harness 中没有任何环节依据它做决策，压缩改为直接读取 `measure()`。UI 用测得的压力除以为所选模型单独解析出的容量来计算占用率。
-
-[Agent Note](../../../.agents/notes/implemented/architecture/2026-07-29-projected-token-usage-and-request-context.zh.md) 记录了否决「让这对值保持原子」方案的那次对比。需要同一边界精确数字的消费方应在自己的请求边界调用 `measure()`，而不是读取该投影。

+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释服务背后的设计；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+服务建立在一个 fold 与一个锚点之上。每个会话都有隔离的回放状态——已消费事件游标、规范请求标头、已计价表面、步骤边界与测量锚点——通过折叠持久日志推进。只有当提供方用量的规范 envelope 匹配、且其总量不低于同一次调用的完整路由定价时，才用它锚定测量；否则会估算完整 envelope 与表面。与路由无关的 `heuristicTokens` 字段使替换影子价投影保持确定性。fold 是整体且分配全新的：格式错误事件会在任何变更前抛出，因此同一份日志每次重试都以相同方式失败。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | `TokenMeter` 服务：回放状态、fold、`measure()` 与 `estimateMessage()` |

+| [`src/turn-usage.ts`](src/turn-usage.ts) | 精确逐次尝试与逐 Turn 用量的纯 fold |
+
+### Fold 流程
+
+每次 `measure()` 调用都把 fold 同步到当前持久尾部，然后读取一份连贯快照。fold 跟踪完整请求标头快照、步骤边界、表面追加与替换、成功 assistant 消息、提供方用量，以及每条 assistant 消息引用的分片 seq。用量锚点的提供方输出从精确引用的分片 seq 重新组装；显式空列表表示已知空提供方流，而缺失的遗留列表保守地把持久 assistant 输出视为提供方输出。
+
+### 投影语义
+
+投影单元不共享完整表面 fold，因为其持久状态必须保持 O(1)。`surface-projection.ts` 为追加计价，并消费紧邻替换之前记录的影价；它只保留一个运行总量与至多一个待处理 claim，不保留逐节点价格。因此完全计量的日志在每个事件边界都与 `measure()` 的 plan/commit fold 一致。没有相邻匹配 claim 的替换保持有界投影不变，因为投影无法重建被替换范围。单一最后用量样本槽依赖一条会话日志顺序性质：一旦更晚的步骤报告用量，合法日志绝不会再为更早步骤报告用量。

 English | [中文](README.zh.md)
 
-The language-server capability seam: an LSP Service Definition, a generic stdio provider, and the model-facing `lsp` tool. All **product** packages.
+## Summary
+
+The lsp group gives agents precise, language-server-backed code navigation: go to a symbol's definition, find its references, jump to its implementations, or read hover documentation, without the model ever knowing which server answers. The capability is split across three product packages: the `dsh-lsp` seam (`ctx.lsp`) that selects a provider by file extension and normalizes results, the `dsh-lsp-stdio` provider that drives configured local language-server commands, and the model-facing `dsh-tool-lsp` tool that owns the `lsp` schema, prompt, and presentation. Only the provider and the tool do anything when loaded; deployments configure server commands and extension mappings explicitly, and the group ships no language server of its own.

 | Package | Role | ctx key |
 |---|---|---|
-| `lsp/` | Service Definition (provider registry by branded id + extension mapping, per-query selection, vocabulary, `LspError`) | `ctx.lsp` |
-| `lsp-stdio/` | Generic multi-server stdio backend over `ctx.fs` and `ctx.subprocess` (JSON-RPC, transient-open queries) | (registers providers on `ctx.lsp`) |
-| `tool-lsp/` | Model-facing `lsp` tool (four operations, one-based UTF-16 cursor coordinates) | (registers on `ctx.tools`) |
+| [`lsp/`](lsp/README.md) | Defines the code-navigation service: provider selection by file extension, four normalized read-only operations, and structured errors | `ctx.lsp` |
+| [`lsp-stdio/`](lsp-stdio/README.md) | Drives configured stdio language-server commands as providers over `ctx.fs` and `ctx.subprocess` | registers on `ctx.lsp` |
+| [`tool-lsp/`](tool-lsp/README.md) | Exposes precise code navigation to the model through the `lsp` tool | registers on `ctx.tools` |
 
-The Service Definition lives at `lsp/lsp/`. The seam exposes exactly four semantic operations — `goToDefinition`, `findReferences`, `goToImplementation`, `hover` — and no generic JSON-RPC escape hatch, so a provider swap does not change how the model asks for navigation and no protocol payload or unreviewed mutation reaches the model contract. Providers register **capabilities**, not tools; `tool-lsp` is the only owner of the model-facing name, schema, prompt guidance, and presentation.
+Providers register capabilities, not tools: `tool-lsp` is the only owner of the model-facing name, schema, prompt guidance, and presentation, so swapping a provider never changes how the model asks for navigation.
 
-See the [LSP capability seam Agent Note](../../.agents/notes/implemented/architecture/2026-07-15-lsp-capability-seam.md) for the design rationale, including why documents open transiently per query, why the stdio host consumes the shared filesystem/subprocess execution world, and why extension ownership is exclusive within one runtime.

-语言服务器能力 seam：LSP Service Definition、通用 stdio 提供方，以及面向模型的 `lsp` 工具。这些全是**产品**包。
+## 概述
+
+lsp 组为 agent 提供精确的、由语言服务器支撑的代码导航：转到符号的定义、查找其引用、跳转到其实现，或阅读悬停文档，而模型无需知道是哪个服务器在应答。该能力拆分为三个产品包：`dsh-lsp` seam（`ctx.lsp`）按文件扩展名选择提供方并规范化结果，`dsh-lsp-stdio` 提供方驱动配置好的本地语言服务器命令，面向模型的 `dsh-tool-lsp` 工具拥有 `lsp` 的 schema、提示词与呈现。只有提供方与工具在加载后才实际做事；部署需要显式配置服务器命令与扩展名映射，本组自身不随附任何语言服务器。

 # @deepseek-ai/dsh-lsp-stdio
 
 English | [中文](README.zh.md)
 
-A **generic stdio language-server backend** for `ctx.lsp`. One plugin instance accepts a named server table and registers one isolated provider per entry. It reads through `ctx.fs` and launches through `ctx.subprocess`, so the server and source always inhabit the mounted execution world. This is a generic host, not a language-server catalog or installer — deployments configure commands and mappings explicitly; presets belong in `cordis.yml` overlays.
+## Summary
 
-Namespace plugin (`name` / `inject` / `Config` / `apply`, no default export).
+`dsh-lsp-stdio` turns configured local language-server commands into providers on `ctx.lsp`: give it a table of server commands and extension-to-language mappings, and agents get semantic code navigation over the files in those languages — definitions, references, implementations, and hover — served by real language servers. One plugin instance registers one isolated provider per configured server; each provider lazily starts one server process per workspace and opens the queried document transiently, so no document state accumulates between queries. Servers and sources always live in the mounted filesystem and subprocess execution world. It is a generic host, not a language-server catalog or installer — deployments configure commands explicitly. This package trusts its configured servers and adds no sandbox of its own.
 
-## What it does
+## Table of Contents
 
-- Resolves every server-local setting before registration; an invalid mapping or registration conflict rolls back earlier entries, so a failed load leaves no provider routes.
-- Lazily single-flights one server process per `(server id, canonical workspace target)`. A live server error is not replayed; if the selected pooled transport fails before or during a read-only query, the provider awaits its disposal and retries that query once on a fresh process.
-- Uses a compatibility-first **transient-open** sequence per query: resolve and byte-bound the source while streaming it through `ctx.fs`, `textDocument/didOpen` (version 1, full text), the requested request, then `textDocument/didClose` in `finally`. A failed or canceled `didOpen` write terminates the instance before the pool can reuse it. Documents close after each call, so the first version needs no `didChange`, content cache, or document LRU.
-- Serializes each source-read/open/query/close lifecycle through one abortable per-workspace queue so queued calls read current source only when their turn starts; distinct workspaces run in parallel. Provider disposal aborts filesystem and protocol work, awaits workspace lookups that have not entered a queue, then drains every queue and server.
-- After protocol shutdown fails, terminates the server's descendant tree through the subprocess seam (POSIX process-group signaling; Windows `taskkill /T /F`). Tree-kill delivery is contained like every group signal — it races server exit — and quiescence is confirmed by the handle's tree-liveness wait rather than by the kill's own outcome.
-- Resolves the server executable, cwd, process, and protocol streams through `ctx.subprocess`; `initialize.processId` is `null` because another machine or PID namespace must not monitor the harness process.
-- Uses `ctx.fs` canonical containment, file URIs, and streamed text validation, but emits no `fs/observed`: only the LSP result is model-visible, so a query does not satisfy read-before-write policy.

-## Configuration
+-----
 
-The `servers` record key is the stable provider id reserved on `ctx.lsp`; each value has this shape:
+<a id="use-this-package"></a>
+## Use this package
 
-| Server key | Default | Meaning |
+Mount this provider when a deployment has local language servers — for example `typescript-language-server` — and wants the harness to navigate code through them. It needs filesystem and subprocess providers for the same execution world, plus the `dsh-lsp` seam and, for model access, `dsh-tool-lsp`.
+
+### Minimal configuration
+
+The `servers` record maps each stable provider id to one server command. The provider resolves every executable at load after credential scrubbing, so a bad entry prevents every provider from registering; processes launch lazily on the first matching query.
+
+```yaml
+- name: '@deepseek-ai/dsh-fs-local'
+- name: '@deepseek-ai/dsh-subprocess-local'
+- name: '@deepseek-ai/dsh-lsp'
+- name: '@deepseek-ai/dsh-lsp-stdio'
+  config:
+    servers:
+      typescript:
+        command: typescript-language-server
+        args: ['--stdio']
+        extensionToLanguage:
+          '.ts': typescript
+- name: '@deepseek-ai/dsh-tool-lsp'
+```
+
+| Field | Default | Meaning |
 |---|---|---|
-| `command` | (required) | Executable to spawn — absolute, or resolved on the child PATH at load. Launch uses no shell. |
-| `args` | `[]` | Arguments passed to the executable. |
-| `env` | `{}` | Extra env merged on top of the credential-scrubbed ambient env (vars matching `KEY`/`PASSWORD`/`SECRET`/`TOKEN` are not forwarded); an explicit `DSH_*` entry merges after the seam's scrub of ambient ones. |
-| `extensionToLanguage` | (required) | Lowercase leading-dot extension → LSP language id (e.g. `{ '.ts': 'typescript' }`). |
-| `initializationOptions` | `null` | Static `initialize` options forwarded to the server. |
-| `configuration` | `null` | Static answer to every `workspace/configuration` item. |
-| `maxMessageBytes` | `16000000` | Largest single framed message accepted from the server. |
-| `maxStderrBytes` | `1000000` | Largest stderr tail retained for diagnostics. |
-| `maxDocumentBytes` | `4000000` | Largest source file this host will open. |
-| `shutdownTimeoutMs` | `5000` | Graceful `shutdown`/`exit` budget before escalation. |
-| `killGraceMs` | `2000` | Grace for request cancellation and for SIGTERM→SIGKILL escalation. |
+| `command` | required | Executable to spawn — absolute, or resolved on the child PATH at load; launched without a shell |
+| `extensionToLanguage` | required | Lowercase leading-dot extension → LSP language id (e.g. `{ '.ts': 'typescript' }`) |
+| `args` | `[]` | Arguments passed to the executable |
+| `env` | `{}` | Extra env merged over the credential-scrubbed ambient env; variables matching `KEY`/`PASSWORD`/`SECRET`/`TOKEN` and all `DSH_*` names are not forwarded |
+| `initializationOptions` | `null` | Static `initialize` options forwarded to the server |

-`servers` must contain at least one entry, and every id must be non-empty. Timer budgets must be positive integers no greater than Node's `2_147_483_647` ms timer limit. All executables resolve at load after credential scrubbing; a bad later entry prevents every provider from registering. Processes launch lazily on the first matching query.
+`servers` must contain at least one entry with non-empty ids; timer budgets must be positive integers within Node's timer range, and byte caps must be positive. The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-lsp-stdio) is the exhaustive source for every accepted field.
 
-## Protocol behavior
+### What a query does
 
-Initialization advertises `general.positionEncodings: ['utf-16']`, `workspace: { workspaceFolders: true, configuration: true }`, `textDocument.hover.contentFormat: ['markdown', 'plaintext']`, and `linkSupport: true` for definition and implementation, with no dynamic registration. The server's returned capabilities are authoritative: an unsupported operation, or synchronization without transient open/close, fails the query. An omitted server `positionEncoding` defaults to `utf-16`; any other value is a protocol error. The client answers `workspace/configuration` from static config, accepts lifecycle bookkeeping requests, and rejects `workspace/applyEdit` — it never applies edits or runs commands. Navigation maps `Location` directly and `LocationLink` from `targetUri` + `targetSelectionRange`; hover normalization takes valid `MarkupContent.value`, preserves string `MarkedString`s, renders language-tagged values as fenced code, and joins arrays with one blank line. Missing results, malformed ranges or positions, and malformed hover encodings fail as structured `LSP_MALFORMED_RESPONSE` errors.
+On the first query for a workspace, the provider launches one server process for that workspace and keeps it pooled. Each query reads the current source through `ctx.fs`, opens it in the server (`textDocument/didOpen`), runs the requested operation, and closes it — so the server always sees current text and no document state persists between calls. Queries to one server and workspace run one at a time; different workspaces run in parallel. If the pooled process fails before or during a read-only query, the provider retries that query once on a fresh process.
 
-## Security boundary
+### Observable success and failures
 
-The provider trusts its configured server and claims no sandbox confinement. It delegates canonical identity, containment, regular-file streaming, UTF-8 validation, and file-URI encoding to `ctx.fs`; it rejects missing, non-regular, non-UTF-8, oversized, or canonically out-of-workspace query sources before server startup. Containment is evaluated before the stream opens and does not promise stable-handle identity across concurrent path replacement. Result locations may be external, but an external path cannot become a query source. A deployment must mount filesystem and subprocess providers for the same execution world; split-world composition is invalid.
+A successful navigation returns normalized locations, and hover returns normalized text or a no-hover notice; empty results are successful no-result responses. The query fails when the server does not support the operation or the transient open/close synchronization (`LSP_UNSUPPORTED_OPERATION`), when the source is missing, non-regular, non-UTF-8, oversized, or outside the canonical workspace (rejected before the server starts), or when the server returns a malformed payload (`LSP_MALFORMED_RESPONSE`). A hard-killed harness leaves servers running until they exit on their own — graceful shutdown happens only through service disposal.
 
+### Security boundary
+
+This provider trusts its configured server and adds no sandbox confinement; the server receives the filesystem and process authority of the mounted execution world. It rejects query sources that are missing, non-regular, non-UTF-8, oversized, or canonically outside the workspace before server startup. Result locations may point outside the workspace, but an external path can never become a query source. Mount filesystem and subprocess providers for the same execution world — a split-world composition is invalid.

+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the provider and where the code realizes them; observable behavior is covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+- **Generic host, not a catalog.** Deployments configure commands and mappings explicitly; presets belong in `cordis.yml` overlays, not in this package.
+- **Compatibility-first transient open.** Every query runs `didOpen` (version 1, full text) → request → `didClose`, so the server always sees current bytes and the first version needs no `didChange`, content cache, or document LRU.
+- **Read before spawn.** The source is resolved, contained, and byte-bounded inside the workspace queue before any process is created, so a queued query sees current bytes when its turn starts and an invalid source cannot leave an idle process pooled.
+- **One pooled process per canonical workspace.** Instances are single-flighted per `(server id, canonical workspace target)`; a transport failure retries the read-only query once on a fresh process after awaiting disposal.
+- **Per-workspace serialization.** One abortable queue per workspace serializes source-read/open/query/close lifecycles; distinct workspaces run in parallel, and a cancellation that fails to stop a server terminates only that instance.
+- **Bounded teardown.** Graceful `shutdown`/`exit` escalates through tree termination (process-group signaling on POSIX, `taskkill /T /F` on Windows); quiescence is confirmed by awaiting process-tree exit, not by the kill outcome.
+- **Execution-world pairing.** Servers launch through `ctx.subprocess` with `processId: null` (another machine or PID namespace must not monitor the harness), sources read through `ctx.fs`, and no `fs/observed` event is emitted — only the LSP result is model-visible.

+### Protocol behavior
+
+Initialization advertises UTF-16 positions, workspace folders and configuration, markdown/plaintext hover, and link support for definition and implementation, with no dynamic registration; the server's returned capabilities are authoritative. An omitted server `positionEncoding` defaults to `utf-16`; any other value fails the query. The client answers `workspace/configuration` from static config, accepts lifecycle bookkeeping requests, and rejects `workspace/applyEdit` — it never applies edits or runs commands. Navigation maps `Location` directly and `LocationLink` from `targetUri` plus `targetSelectionRange`; hover normalization accepts `MarkupContent` and `MarkedString` shapes, preserves string values, renders language-tagged values as fenced code, and joins arrays with one blank line.

 # @deepseek-ai/dsh-lsp-stdio
 
 [English](README.md) | 中文
 
-`ctx.lsp` 的**通用 stdio 语言服务器后端**。一个插件实例接受一张命名服务器表，并逐配置项注册一个隔离的提供方。它通过 `ctx.fs` 读取，并通过 `ctx.subprocess` 启动，因此服务器与源文件始终位于已挂载的执行世界中。这是通用主机，而不是语言服务器目录或安装器：部署需要显式配置命令与映射，预设应放在 `cordis.yml` overlay 中。
+## 概述
 
-Namespace 插件（`name`／`inject`／`Config`／`apply`，无默认导出）。
+`dsh-lsp-stdio` 把配置好的本地语言服务器命令变成 `ctx.lsp` 上的提供方：给它一张服务器命令与扩展名到语言的映射表，agent 就能针对这些语言的文件获得由真实语言服务器服务的语义代码导航——定义、引用、实现与悬停。一个插件实例针对每个配置的服务器注册一个隔离的提供方；每个提供方按工作区惰性启动一个服务器进程，并在查询时临时打开文档，因此查询之间不会累积任何文档状态。服务器与源文件始终位于已挂载的文件系统与子进程执行世界中。它是通用主机，而不是语言服务器目录或安装器——部署需要显式配置命令。本包信任所配置的服务器，自身不提供任何沙箱。
 
-## 功能
+## 目录
 
-- 在注册前解析每项服务器局部设置；无效映射或注册冲突会回滚较早配置项，因此加载失败不会留下提供方路由。
-- 每个 `(server id, canonical workspace target)` 惰性 single-flight 一个服务器进程。服务器仍存活时返回的错误不会触发重试；如果选中的池化传输在只读查询之前或期间发生故障，提供方会等待其 dispose（资源释放）完成，并在新进程上重试该查询一次。
-- 每次查询都使用兼容性优先的**临时打开**序列：通过 `ctx.fs` 流式读取源文件，同时解析并限制其字节数；随后执行 `textDocument/didOpen`（版本 1、完整文本）、所请求操作，再执行位于 `finally` 中的 `textDocument/didClose`。写入 `didOpen` 失败或取消时，会在池复用该实例前将其终止。文档在每次调用后关闭，因此第一版不需要 `didChange`、内容 cache 或文档 LRU。
-- 通过一条逐 Workspace、可中止的队列，串行执行每个源读取／打开／查询／关闭生命周期，因此排队调用只会在轮到自身时读取当前源；不同 Workspace 并行运行。提供方 dispose 会中止文件系统与协议工作，等待尚未进入队列的 Workspace 查找完成，随后排空每条队列与每个服务器。
-- 协议 shutdown 失败后，经由子进程 seam 终止服务器后代树（POSIX 进程组信号；Windows `taskkill /T /F`）。树终止的投递结果与所有进程组信号一样被就地吸收，不向外抛出（投递与服务器退出存在竞态）；服务器是否完全停稳，由句柄的进程树存活等待确认，而非由这次终止自身的结果确认。
-- 通过 `ctx.subprocess` 解析服务器可执行文件、cwd、进程和协议流；`initialize.processId` 为 `null`，因为另一台机器或 PID namespace 不得监视 harness 进程。
-- 使用 `ctx.fs` 提供的规范化包含关系、文件 URI 与流式文本验证，但不发出 `fs/observed`：只有 LSP 结果对模型可见，因此查询不满足先读后写策略。

+### 最小配置
+
+`servers` 记录把每个稳定的提供方 id 映射到一条服务器命令。提供方会在清理 credential 后于加载时解析每个可执行文件，因此一个坏配置项会阻止所有提供方注册；进程在第一次匹配查询时惰性启动。

-## 协议行为
+### 查询做什么
 
-初始化会声明 `general.positionEncodings: ['utf-16']`、`workspace: { workspaceFolders: true, configuration: true }`、`textDocument.hover.contentFormat: ['markdown', 'plaintext']`，以及定义与实现使用的 `linkSupport: true`，且不进行动态注册。服务器返回的能力具有最终决定权：不受支持的操作，或缺少临时打开／关闭的同步方式，会使查询失败。服务器省略 `positionEncoding` 时默认为 `utf-16`；其他值都属于协议错误。客户端通过静态配置回答 `workspace/configuration`，接受生命周期记账请求，并拒绝 `workspace/applyEdit`：它绝不应用编辑或运行命令。导航直接映射 `Location`，并从 `LocationLink` 的 `targetUri` + `targetSelectionRange` 映射；hover 规范化会取得有效的 `MarkupContent.value`，保留 string `MarkedString`，把带 language tag 的值渲染为围栏代码，并用一个空行连接数组。缺失结果、格式错误的范围或位置，以及格式错误的 hover 编码，都会以结构化 `LSP_MALFORMED_RESPONSE` 错误的形式失败。
+首次查询某个工作区时，提供方会为该工作区启动一个服务器进程并放入池中。每次查询通过 `ctx.fs` 读取当前源文件，在服务器中打开它（`textDocument/didOpen`），执行所请求的操作，然后关闭——因此服务器始终看到当前文本，调用之间不会残留任何文档状态。同一服务器与工作区的查询一次只执行一个；不同工作区并行运行。如果池化进程在只读查询之前或期间发生故障，提供方会在新进程上重试该查询一次。
 
-## 安全边界
+### 可观察的成功与失败
 
-提供方信任其配置的服务器，不提供任何沙箱隔离。它把规范化身份、包含关系、普通文件流式读取、UTF-8 验证和文件 URI 编码委托给 `ctx.fs`；并在服务器启动前拒绝缺失、非普通文件、非 UTF-8、过大，或规范化后位于 Workspace 外部的查询源。包含关系在打开流之前评估，不承诺在并发路径替换期间保持稳定句柄身份。结果位置可以在外部，但外部路径不能成为查询源。部署必须挂载描述同一执行世界的文件系统与进程管理提供方；分裂世界组合无效。
+成功的导航返回规范化位置，悬停返回规范化文本或无可悬停提示；空结果是成功的无结果响应。当服务器不支持该操作或临时打开／关闭同步（`LSP_UNSUPPORTED_OPERATION`）、源文件缺失、非普通文件、非 UTF-8、过大或位于规范工作区之外（在服务器启动前被拒绝），或服务器返回格式错误的载荷（`LSP_MALFORMED_RESPONSE`）时，查询会失败。被强制杀死的 harness 会让服务器继续运行直到自行退出——优雅关闭只发生在服务释放时。
 
+### 安全边界
+
+本提供方信任所配置的服务器，不提供任何沙箱隔离；服务器获得的是已挂载执行世界的文件系统与进程权限。它会在服务器启动前拒绝缺失、非普通文件、非 UTF-8、过大或规范化后位于工作区之外的查询源。结果位置可以指向工作区外部，但外部路径永远不能成为查询源。为同一执行世界挂载文件系统与子进程提供方——分裂世界组合无效。

+本节解释提供方背后的设计决策并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+- **通用主机，不是目录。** 部署显式配置命令与映射；预设应放在 `cordis.yml` overlay 中，而不是本包内。
+- **兼容性优先的临时打开。** 每次查询都执行 `didOpen`（版本 1、完整文本）→ 请求 → `didClose`，因此服务器始终看到当前字节，第一版不需要 `didChange`、内容 cache 或文档 LRU。
+- **先读后启动。** 源文件在工作区队列内先完成解析、包含关系检查与字节限制，然后才创建任何进程，因此排队查询只会在轮到自身时读取当前字节，无效源文件也不会留下空闲的池化进程。
+- **每个规范工作区一个池化进程。** 实例按 `(server id, canonical workspace target)` 进行 single-flight；传输故障会在等待释放完成后于新进程上重试一次该只读查询。
+- **逐工作区串行化。** 每个工作区一条可中止队列，串行执行源读取／打开／查询／关闭生命周期；不同工作区并行运行，无法停止服务器的取消只会终止该实例。
+- **有边界的释放。** 优雅 `shutdown`／`exit` 升级为进程树终止（POSIX 进程组信号，Windows `taskkill /T /F`）；是否完全停稳由等待进程树退出确认，而非由终止操作自身的结果确认。
+- **执行世界配对。** 服务器通过 `ctx.subprocess` 启动，`processId: null`（另一台机器或 PID namespace 不得监视 harness）；源文件通过 `ctx.fs` 读取；不发出 `fs/observed` 事件——只有 LSP 结果对模型可见。

-The **LSP capability seam**: an abstract `LspService` (`ctx.lsp`) defining WHAT semantic code navigation the harness has — go to definition, find references, find implementations, hover — over language-server providers, without binding the model contract to local subprocesses.
+## Summary
 
-This package owns the Service Definition role of the LSP capability:
+`dsh-lsp` provides the harness's language-server code navigation: an agent can go to a symbol's definition, find its references, jump to its implementations, or read hover documentation, and the code-navigation service (`ctx.lsp`) routes each query to the language-server provider that owns the file's extension. Providers register by branded id and file extension, so a provider swap never changes how navigation is requested or what the model sees. The service exposes exactly four read-only operations and no generic JSON-RPC escape hatch, and it contributes no prompt or tool schema itself — the model-facing `lsp` tool lives in `dsh-tool-lsp`. Compose it with a provider such as `dsh-lsp-stdio` and the tool to give agents precise navigation; this package does nothing on its own.

+## Use this package
+
+Mount a language-server provider and the `lsp` tool to give agents semantics-based code navigation that text search cannot reliably provide — distinguishing same-named functions, following import aliases, connecting an interface to its implementations, or reading inferred types. This package is the service those packages register against; it defines no UI, tool, or provider of its own.
+
+### When to choose it
+
+Choose this service when a deployment wants model-visible code navigation backed by language servers. It covers read-only navigation — definitions, references, implementations, and hover — and deliberately omits mutations (rename, code actions, formatting), symbol lists, and diagnostics. The service is provider-neutral: local stdio servers, remote servers, and sandbox-native providers register the same way, so replacing the backend does not change what the model sees or how it asks.
+
+### Composing a navigation stack
+
+The seam needs a provider and a consumer to do anything. A minimal composition mounts the service, a stdio provider, and the tool:
+
+```yaml
+- name: '@deepseek-ai/dsh-fs-local'
+- name: '@deepseek-ai/dsh-subprocess-local'
+- name: '@deepseek-ai/dsh-lsp'
+- name: '@deepseek-ai/dsh-lsp-stdio'
+- name: '@deepseek-ai/dsh-tool-lsp'
+```
+
+Server commands, extension mappings, and the filesystem/subprocess pairing are configured in the provider and tool packages; see [dsh-lsp-stdio](../lsp-stdio/README.md) and [dsh-tool-lsp](../tool-lsp/README.md).
+
+### The four operations
+
+Each query asks one of four semantic questions at a cursor position in a source file; results are normalized locations or hover content, never raw protocol payloads.
+
+| Operation | What the agent gets |
 |---|---|
-| `@deepseek-ai/dsh-lsp` (this) | Service Definition: the service, provider registry keyed by branded id + extension mapping, per-query selection, request/result vocabulary, the `LspError` taxonomy |
-| `@deepseek-ai/dsh-lsp-stdio` | Service Provider: a generic local backend that registers configured stdio language-server providers |
-| `@deepseek-ai/dsh-tool-lsp` | Consumer: the model-facing `lsp` tool over `ctx.lsp` |
+| `goToDefinition` | The declaration site(s) of the symbol at the cursor |
+| `findReferences` | Every reference, always including the declaration |
+| `goToImplementation` | The concrete implementation site(s) |
+| `hover` | Normalized documentation for the symbol, or none |
 
-The seam exposes exactly four semantic operations — `goToDefinition`, `findReferences`, `goToImplementation`, `hover` — and no generic JSON-RPC escape hatch, so no protocol payload or unreviewed command/mutation reaches a provider through `ctx.lsp`.
+`findReferences` always includes declarations, so impact analysis never misses the defining site. Positions are zero-based UTF-16 on the wire; the model-facing tool accepts one-based cursor coordinates and converts them.
 
-## Service API (`ctx.lsp`)
+### Failures and recovery
 
-| Member | Semantics |
+A query fails with the structured error `LSP_UNAVAILABLE` when no registered provider handles the file's extension — add a provider for that extension or query a supported file. Invalid or conflicting provider registrations fail with `LSP_INVALID_PROVIDER` or `LSP_CONFLICT` before any route is published, and a query against a disposed provider fails with `LSP_DISPOSED`. Consumers catch `LspError` and route on its stable `code`; through the tool, these surface as error results the model can read.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the seam and where the code realizes them; observable behavior is covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+- **Capability seam, Service Definition role.** The package owns `ctx.lsp` and the provider registry; providers register capabilities, not tools, and `dsh-tool-lsp` is the only owner of the model-facing surface.
+- **Atomic registration.** `registerProvider()` validates and conflict-checks everything before mutating: an invalid or conflicting registration publishes nothing, and its disposer releases the id and every extension reservation together.
+- **Order-independent selection.** `query()` routes by the file's final extension, normalized to lowercase leading-dot form; registration and HMR order never change routing. The language id only synchronizes the transient document and never participates in selection.
+- **Closed vocabulary.** The four-operation union is closed — adding an operation is a compile-enforced change across the seam, providers, and the tool. There is no JSON-RPC escape hatch, and every request field is required, so there is no `resolve()` step.
+- **Provider-owned workspace coordinate.** Location results carry the provider's canonical workspace URI, so consumers relativize file URIs in the execution world's namespace instead of applying host-platform path rules.
+
+### Source map
+
+| File | Role |
 |---|---|
-| `registerProvider(provider)` | Register a backend, atomically reserving its branded `id` and every normalized file extension. Any invalid input or conflict publishes nothing and throws `LspError` (`LSP_INVALID_PROVIDER` / `LSP_CONFLICT`). Returns a disposer releasing all reservations. Disposed with the calling fiber. |
-| `query(request, signal?)` | Select the provider by the file's final extension, derive the `languageId` from that provider's mapping, and run one query. No match throws `LspError` `LSP_UNAVAILABLE`. |
+| [`src/index.ts`](src/index.ts) | Plugin entry: `Lsp` service, `registerProvider`/`query`, `finalExtension`, `LspError` codes |
+| [`src/types.ts`](src/types.ts) | Seam vocabulary: request, result, provider, and service contracts |
+| [`src/brand.ts`](src/brand.ts) | `LspProviderId` branded-id type and factory |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; routes are private atomic state) |
 
-Selection is per query and order-independent: a provider owns a set of extensions exclusively, so registration and HMR order never change routing. Extension keys normalize to lowercase, leading-dot form; the `languageId` only synchronizes the transient document, never participates in selection. The first version has no glob, language-id, or explicit route selector.
+### Registration and selection lifecycle
 
-Providers register **capabilities**, not tools. `dsh-tool-lsp` is the only owner of the model-facing name, description, prompt guidance, schema, and presentation.
+Registration and disposal run through `ctx.effect()`, so provider routes live and die with the registering fiber. `finalExtension()` splits on both path separators and returns `''` for names without an extension or leading-dot dotfiles, which no route matches. `LspError` extends `HarnessError` with stable codes (`LSP_INVALID_PROVIDER`, `LSP_CONFLICT`, `LSP_UNAVAILABLE`, `LSP_DISPOSED`, `LSP_UNSUPPORTED_OPERATION`, `LSP_MALFORMED_RESPONSE`) that callers route on instead of parsing `message`.
 
-## Vocabulary
+</details>
 
-`LspQueryRequest` (`operation`, `filePath`, `position`, `workspaceRoot`) — every field required, so no field needs implementation defaulting and there is no `resolve()` step. Positions and ranges are zero-based UTF-16, matching the protocol; the tool owns the one-based cursor convention. `findReferences` always includes declarations — providers enforce this internally, so callers get no flag. `LspQueryResult` is a CLOSED discriminated union: `{ kind: 'locations'; locations; resolvedWorkspaceUri }` for navigation, `{ kind: 'hover'; hover }` for hover (content or `null`) — consumers `switch` to exhaustiveness so a new arm breaks compilation until handled. `resolvedWorkspaceUri` is the provider's canonical workspace `file:` URI; callers relativize location URIs against it instead of applying host-platform path rules to the possibly symlinked request root. See `src/types.ts` for the full contracts and `src/index.ts` for the `LspError` codes, including `LSP_DISPOSED` and `LSP_MALFORMED_RESPONSE`.

-**LSP 能力 seam**：抽象 `LspService`（`ctx.lsp`）定义 harness 具备哪些语义代码导航能力（转到定义、查找引用、查找实现、悬停），并通过语言服务器提供方实现，不把模型约定绑定到本地子进程。
+## 概述
 
-本包承担 LSP 能力的 Service Definition 角色：
+`dsh-lsp` 为 harness 提供语言服务器代码导航：agent 可以转到符号的定义、查找其引用、跳转到其实现或阅读悬停文档，代码导航服务（`ctx.lsp`）会把每个查询路由到拥有该文件扩展名的语言服务器提供方。提供方按品牌化 id 与文件扩展名注册，因此更换提供方绝不会改变请求导航的方式，也不会改变模型看到的内容。该服务恰好暴露四种只读操作，没有通用 JSON-RPC 逃生口；它自身不贡献提示词或工具 schema——面向模型的 `lsp` 工具位于 `dsh-tool-lsp`。与 `dsh-lsp-stdio` 之类的提供方及该工具组合，即可为 agent 提供精确导航；本包单独加载时什么也不做。

+## 使用本包
+
+挂载语言服务器提供方与 `lsp` 工具，即可为 agent 提供文本搜索无法可靠给出的、基于语义的代码导航——区分同名函数、跟随导入别名、把接口连接到其实现，或读取推断出的类型。本包就是这些包所注册的服务；它自身不定义任何 UI、工具或提供方。
+
+### 何时选择
+
+当部署希望模型可见的代码导航由语言服务器支撑时，选择此服务。它覆盖只读导航——定义、引用、实现与悬停——并刻意排除修改（重命名、code action、格式化）、符号列表与诊断。该服务提供方无关：本地 stdio 服务器、远程服务器与沙箱原生提供方都以相同方式注册，因此更换后端不会改变模型看到的内容或请求方式。
+
+### 组合导航栈
+
+seam 需要提供方与消费方才能发挥作用。最小组合挂载服务、stdio 提供方与工具：
+
+```yaml
+- name: '@deepseek-ai/dsh-fs-local'
+- name: '@deepseek-ai/dsh-subprocess-local'
+- name: '@deepseek-ai/dsh-lsp'
+- name: '@deepseek-ai/dsh-lsp-stdio'
+- name: '@deepseek-ai/dsh-tool-lsp'
+```
+
+服务器命令、扩展名映射与文件系统／子进程配对在提供方与工具包中配置；见 [dsh-lsp-stdio](../lsp-stdio/README.zh.md) 与 [dsh-tool-lsp](../tool-lsp/README.zh.md)。
+
+### 四种操作
+
+每个查询在源文件的某个光标位置提出四个语义问题之一；结果是被规范化的位置或悬停内容，绝不是原始协议载荷。
+

+
+### 设计理念
+
+- **能力 seam，Service Definition 角色。** 本包拥有 `ctx.lsp` 与提供方注册表；提供方注册的是能力而非工具，`dsh-tool-lsp` 是面向模型表层的唯一 owner。
+- **原子注册。** `registerProvider()` 在变更前验证并检查全部冲突：无效或冲突的注册不会发布任何内容，其 disposer 会一并释放 id 与全部扩展名保留。
+- **与顺序无关的选择。** `query()` 按文件的最终扩展名（规范化为小写、以点开头的形式）路由；注册与 HMR 顺序绝不会改变路由。language id 只用于同步临时文档，绝不参与选择。
+- **封闭的词汇。** 四种操作的联合是封闭的——新增操作是跨 seam、提供方与工具的编译期强制变更。没有 JSON-RPC 逃生口，且每个请求字段都必填，因此不存在 `resolve()` 步骤。
+- **提供方拥有的工作区坐标。** 位置结果携带提供方的规范工作区 URI，消费方据此在执行世界的命名空间内相对化文件 URI，而不是应用宿主平台路径规则。
+
+### 源码地图
+
+| 文件 | 职责 |
 |---|---|
-| `registerProvider(provider)` | 注册后端，以原子方式保留其品牌化 `id` 与每个规范化文件扩展名。任何无效输入或冲突都不会发布内容，并抛出 `LspError`（`LSP_INVALID_PROVIDER`／`LSP_CONFLICT`）。返回释放所有保留项的 disposer。随调用 fiber 释放。 |
-| `query(request, signal?)` | 按文件最终扩展名选择提供方，从该提供方的映射派生 `languageId`，并运行一次查询。没有匹配项时抛出 `LspError` `LSP_UNAVAILABLE`。 |
+| [`src/index.ts`](src/index.ts) | 插件入口：`Lsp` 服务、`registerProvider`／`query`、`finalExtension`、`LspError` code |
+| [`src/types.ts`](src/types.ts) | seam 词汇：请求、结果、提供方与服务约定 |
+| [`src/brand.ts`](src/brand.ts) | `LspProviderId` 品牌化 id 类型与工厂 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；路由是私有原子状态） |
 
-选择逐查询进行且与顺序无关：一个提供方独占一组扩展名，因此注册和 HMR（热模块替换）顺序绝不会改变路由。扩展名 key 规范化为小写且以点开头；`languageId` 只用于同步临时文档，绝不参与选择。第一版没有 glob、language-id 或显式路由 selector。
+### 注册与选择生命周期
 
-提供方注册的是**能力**而非工具。`dsh-tool-lsp` 是面向模型的名称、描述、提示词指引、schema 和呈现的唯一 owner。
+注册与释放通过 `ctx.effect()` 执行，因此提供方路由随注册 fiber 一同存活与消亡。`finalExtension()` 按两种路径分隔符切分，对没有扩展名的名称或点开头的 dotfile 返回 `''`，任何路由都不会匹配。`LspError` 扩展 `HarnessError`，携带稳定的 code（`LSP_INVALID_PROVIDER`、`LSP_CONFLICT`、`LSP_UNAVAILABLE`、`LSP_DISPOSED`、`LSP_UNSUPPORTED_OPERATION`、`LSP_MALFORMED_RESPONSE`），调用方据此路由，而不是解析 `message`。
 
-## 词汇
+</details>
 
-`LspQueryRequest`（`operation`、`filePath`、`position`、`workspaceRoot`）：每个字段都必填，因此没有字段需要实现默认值，也不存在 `resolve()` 步骤。位置与范围使用从零开始的 UTF-16，与协议一致；工具拥有从 1 开始的光标约定。`findReferences` 始终包含声明，提供方在内部强制执行，因此调用方没有 flag。`LspQueryResult` 是封闭的判别联合：导航使用 `{ kind: 'locations'; locations; resolvedWorkspaceUri }`，悬停使用 `{ kind: 'hover'; hover }`（内容或 `null`）；消费方通过 `switch` 实现穷尽检查，因此新增分支会使编译失败，直到完成处理。`resolvedWorkspaceUri` 是提供方的规范工作区 `file:` URI；调用方相对化位置 URI 时以它为基准，而不是对可能含符号链接的请求根应用宿主平台路径规则。完整约定见 `src/types.ts`；`src/index.ts` 给出 `LspError` code，包括 `LSP_DISPOSED` 和 `LSP_MALFORMED_RESPONSE`。

 # @deepseek-ai/dsh-tool-lsp
 
 English | [中文](README.zh.md)
 
-The model-facing **`lsp` tool** over `ctx.lsp`: one read-only tool with four operations for precise code navigation. It owns the model schema, prompt guidance, coordinate conversion, result limits and formatting, and UI presentation; it imports no provider.
+## Summary
 
-Namespace plugin (`name` / `inject` / `Config` / `apply`, no default export). Injects `tools`, `lsp`, and `systemPrompt`.
+`dsh-tool-lsp` gives the model a single read-only `lsp` tool for precise code navigation over the LSP seam: go to a symbol's definition, find its references, jump to its implementations, or read hover documentation. The tool owns everything the model sees — name, schema, prompt guidance, result formatting, and UI presentation — and never depends on which language server backs a query. Positions are one-based UTF-16 cursor coordinates, which the tool converts to the seam's zero-based convention. Results are bounded location lists or normalized hover text with explicit no-result and truncation markers. Compose it with a provider such as `dsh-lsp-stdio` and the `dsh-lsp` seam to activate navigation.
 
-## The tool
+## Table of Contents
 
-`lsp` accepts `operation` (`goToDefinition` | `findReferences` | `goToImplementation` | `hover`), `file_path`, `line`, and `character`. `line` and `character` are positive, one-based UTF-16 cursor coordinates; the tool converts them to the seam's zero-based positions and converts rendered locations back. `findReferences` includes declarations so impact analysis does not omit the defining site. Provider, language id, workspace root, limits, timeout, initialization, and executable stay outside model input.

+- [Further Exploration](#further-exploration)
+- [Model Experience](#model-experience)
+- [Known Limitations and Deferred Work](#known-limitations-and-deferred-work)
+- [Dev Note](#dev-note)
 
-The tool requires the workspace root from the session `header.cwd`, with no fallback: absence fails as `LSP_WORKSPACE_REQUIRED` before querying. Its canonical result is the complete normalized Service Definition union: `{ kind: "locations", locations, resolvedWorkspaceUri }` or `{ kind: "hover", hover }`; Code Mode can inspect every acquired location and zero-based range directly. Native rendering projects stable, file-grouped `path:line:character` entries against the provider's canonical workspace URI rather than applying host-platform path rules to the session cwd. A `file:` URI becomes a workspace-relative path inside that URI or a URI-derived absolute path outside it; malformed and non-`file:` URIs stay verbatim. Empty locations and `null` hover are successful no-result responses; malformed provider payloads remain structured errors.
+-----
 
-## Configuration
+<a id="use-this-package"></a>
+## Use this package
+
+An agent uses `lsp` when textual matches are ambiguous or before a change that needs precise definitions, implementations, or references; the tool's prompt guidance tells it to prefer `search`/`read` for ordinary navigation.
+
+### The tool
+
+`lsp` takes `operation` (`goToDefinition`, `findReferences`, `goToImplementation`, or `hover`), `file_path`, `line`, and `character`. `line` and `character` are positive one-based UTF-16 cursor coordinates; an off-symbol position may return no results. `findReferences` always includes the declaration, so impact analysis never misses the defining site. Provider choice, language id, workspace root, limits, timeout, and executable stay outside model input.
+
+### What the model gets back
+
+Navigation returns `path:line:character` locations grouped by file (one-based); hover returns normalized text or a no-hover notice. Empty locations and no hover are successful no-result responses. Results are capped first by `maxLocations` and then by `maxResultChars`, with omission and truncation markers inside the complete cap; the caps affect only presentation, not the canonical result value.
+
+### Configuration
 
 | Key | Default | Meaning |
 |---|---|---|
-| `maxLocations` | `100` | Largest number of rendered locations before an omission marker. |
-| `maxResultChars` | `16000` | Largest complete rendered result, including truncation metadata. |
-| `timeoutMs` | `60000` | Tool-call timeout budget, enforced by `dsh-tool-call-timeout-policy`; covers the complete queued open/query/close lifecycle and is not model-configurable. |
+| `maxLocations` | `100` | Largest number of rendered locations before an omission marker |
+| `maxResultChars` | `16000` | Largest complete rendered result, including truncation metadata |
+| `timeoutMs` | `60000` | Tool-call timeout budget enforced by `dsh-tool-call-timeout-policy`; covers the complete queued open/query/close lifecycle and is not model-configurable |
 
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-tool-lsp) is the exhaustive source for every accepted field.
+
+### Failures and recovery
+
+The tool requires a session workspace root (`header.cwd`) with no fallback; absence fails with `LSP_WORKSPACE_REQUIRED` before any query. When no provider handles the file's extension, the query fails with `LSP_UNAVAILABLE`; malformed provider payloads remain structured `LSP_MALFORMED_RESPONSE` errors. These surface to the model as error tool results it can read and route on.

+
+This section explains the design decisions behind the tool and where the code realizes them; observable behavior is covered in [Use this package](#use-this-package).
+
+### Design notes
+
+- **Consumer-only.** The tool runtime-injects only `tools`, `lsp`, and `systemPrompt`, imports no provider, and passes only `exec.signal` to the seam.
+- **Coordinate conversion.** `parseLspArgs` validates that `line` and `character` are positive integers and converts them to the seam's zero-based positions; rendered locations convert back to one-based form.
+- **Canonical result passthrough.** The tool returns the seam's closed union (`{ kind: 'locations', locations, resolvedWorkspaceUri }` or `{ kind: 'hover', hover }`) so native renderers can inspect every acquired location and zero-based range directly.
+- **Execution-world URI rendering.** `renderUri` resolves a `file:` URI against the provider's canonical workspace URI — workspace-relative inside it, URI-derived absolute outside it, verbatim when malformed or not `file:` — never applying host-platform path rules to the session cwd.
+- **Caps after rendering.** `maxLocations` bounds the item count first, then `maxResultChars` bounds the complete rendered text including its omission or truncation marker.
+- **Generic search-card presentation.** `presentLspCall` renders a `{ card: 'generic', kind: 'search', title, locations: [{ path, line }] }` view; the args-derived title carries the operation and one-based cursor, and follow-along focuses the queried line while the title preserves the column.

-面向模型的 **`lsp` 工具**，基于 `ctx.lsp`：一个只读工具，通过四种操作执行精确代码导航。它拥有模型 schema、提示词指引、坐标转换、结果限制与格式化，以及 UI 呈现；不导入任何提供方。
+## 概述
 
-Namespace 插件（`name`／`inject`／`Config`／`apply`，无默认导出）。注入 `tools`、`lsp` 和 `systemPrompt`。
+`dsh-tool-lsp` 通过 LSP seam 为模型提供单一的只读 `lsp` 工具，用于精确代码导航：转到符号的定义、查找其引用、跳转到其实现，或阅读悬停文档。该工具拥有模型看到的一切——名称、schema、提示词指引、结果格式化与 UI 呈现——并且绝不依赖哪个语言服务器应答查询。位置是从 1 开始的 UTF-16 光标坐标，工具会将其转换为 seam 从零开始的约定。结果是有边界的位置列表或规范化悬停文本，带有明确的空结果与截断标记。与 `dsh-lsp-stdio` 之类的提供方及 `dsh-lsp` seam 组合，即可启用导航。
 
-## 工具
+## 目录
 
-`lsp` 接受 `operation`（`goToDefinition` | `findReferences` | `goToImplementation` | `hover`）、`file_path`、`line` 和 `character`。`line` 与 `character` 是正的、从 1 开始的 UTF-16 光标坐标；工具将其转换为 seam 从零开始的位置，并把渲染位置转换回来。`findReferences` 包含声明，因此影响分析不会遗漏定义位置。提供方、language id、工作区根目录、限制、超时、初始化和可执行文件均不进入模型输入。

-该工具要求从会话 `header.cwd` 取得工作区根目录，没有回退值：缺失时会在查询前以 `LSP_WORKSPACE_REQUIRED` 失败。其规范结果是完整的已规范化 Service Definition 联合类型：`{ kind: "locations", locations, resolvedWorkspaceUri }` 或 `{ kind: "hover", hover }`；Code Mode 可以直接检查每个已取得的位置和从零开始的范围。原生渲染以提供方的规范工作区 URI 为基准，投影按文件稳定分组的 `path:line:character` 条目，而不对会话 cwd 应用宿主平台路径规则。`file:` URI 落在该工作区 URI 内时成为工作区相对路径，位于其外时成为从 URI 派生的绝对路径；格式错误的 URI 与非 `file:` URI 保持原样。空位置和 `null` hover 都是成功的无结果响应；格式错误的提供方载荷仍是结构化错误。

+<a id="use-this-package"></a>
+## 使用本包
 
-| Key | 默认值 | 含义 |
+当文本匹配有歧义，或修改前需要精确的定义、实现或引用时，agent 使用 `lsp`；该工具的提示词指引会告诉它，普通导航应优先使用 `search`／`read`。
+
+### 工具
+
+`lsp` 接受 `operation`（`goToDefinition`、`findReferences`、`goToImplementation` 或 `hover`）、`file_path`、`line` 与 `character`。`line` 与 `character` 是正的、从 1 开始的 UTF-16 光标坐标；未落在符号上的位置可能返回空结果。`findReferences` 始终包含声明，因此影响分析绝不会遗漏定义位置。提供方、language id、工作区根目录、限制、超时与可执行文件均不进入模型输入。
+
+### 模型得到什么
+
+导航返回按文件分组的 `path:line:character` 位置行（从 1 开始）；悬停返回规范化文本或无可悬停提示。空位置与无悬停都是成功的无结果响应。结果先由 `maxLocations` 限制，再由 `maxResultChars` 限制，省略与截断标记计入完整上限；这些上限只影响呈现，不影响规范结果值。
+
+### 配置
+
+| 键 | 默认值 | 含义 |
 |---|---|---|
-| `maxLocations` | `100` | 出现省略标记前可渲染位置的最大数量。 |
-| `maxResultChars` | `16000` | 完整渲染结果的最大长度，包括截断元数据。 |
-| `timeoutMs` | `60000` | 由 `dsh-tool-call-timeout-policy` 强制执行的工具调用超时预算；覆盖完整的排队打开／查询／关闭生命周期，且模型不可配置。 |

+
+本节解释工具背后的设计决策并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计说明
+
+- **只做消费方。** 工具运行时只注入 `tools`、`lsp` 与 `systemPrompt`，不导入任何提供方，并且只把 `exec.signal` 传给 seam。
+- **坐标转换。** `parseLspArgs` 验证 `line` 与 `character` 是正整数，并转换为 seam 从零开始的位置；渲染出的位置再转回从 1 开始的形式。
+- **规范结果透传。** 工具返回 seam 的封闭联合（`{ kind: 'locations', locations, resolvedWorkspaceUri }` 或 `{ kind: 'hover', hover }`），原生渲染器可以直接检查每个已取得的位置与从零开始的范围。
+- **执行世界 URI 渲染。** `renderUri` 以提供方的规范工作区 URI 为基准解析 `file:` URI——在其内为工作区相对路径，在其外为从 URI 派生的绝对路径，格式错误或非 `file:` 时原样保留——绝不把宿主平台路径规则应用到会话 cwd。
+- **渲染后再设限。** `maxLocations` 先限制条目数量，`maxResultChars` 再限制包含省略或截断标记在内的完整渲染文本。
+- **通用搜索卡片呈现。** `presentLspCall` 渲染 `{ card: 'generic', kind: 'search', title, locations: [{ path, line }] }` 视图；从 args 派生的标题携带操作与从 1 开始的光标，跟随焦点对准查询行，标题则保留列号。

 # MCP — Model Context Protocol
 
 English | [中文](README.zh.md)
 
-Packages bridging the harness to the MCP ecosystem.
+## Summary
 
-| Package | Role |
+The `mcp/` group connects the harness to the Model Context Protocol (MCP) ecosystem of tool servers. The one package in this group attaches an external server — a filesystem, GitHub, database, or memory server — so its tools are available to the model as native tools under stable server-qualified names. Each server is one configuration entry; nothing ships enabled, so you opt in per server. Only the Tools capability is bridged: MCP resources and prompts are not supported. This page maps the group; the package README owns the per-package contract.

-MCP client bridge plugin: connects to external [Model Context Protocol](https://modelcontextprotocol.io/) servers and registers their tools on `ctx.tools`, making them available to the model as native tools under server-qualified names (`mcp__<serverName>__<rawName>`).
+## Summary
 
-## Usage
+`dsh-mcp-client` attaches external Model Context Protocol (MCP) servers to the harness so their tools work like any native tool. With one configuration entry per server, the model can call that server's tools — a filesystem, GitHub, database, or memory server — under stable names such as `mcp__github__create_issue`. Add it when the model should work with an external tool server; nothing ships enabled, so you opt in. The main cost is the tokens those tool definitions add to every request, and a slow or crashed server can delay startup or leave its tools failing until it recovers. Only tools are bridged: MCP resources and prompts are not supported.

+## Use this package
+
+Add `dsh-mcp-client` when the model should call tools from an external MCP server as if they were native. One configuration entry per server is the entire setup: give the server a short unique name and a transport, and its tools appear as `mcp__<serverName>__<tool>`. Choose stdio when the server runs as a local program and Streamable HTTP when it runs as a service. If you already use MCP tool servers from another client, the same server rows work here.
+
+### Minimal configuration
+
+Add one entry per server; nothing else is required. After the harness starts, the server's tools appear in the model's tool list.

-## Tool naming
+### Tool naming and coexistence
 
-Every MCP tool has two names: the raw MCP name (sent on the wire in `tools/call`) and the public name `mcp__<serverName>__<rawName>` registered on `ctx.tools`. Public names are normalized to the DeepSeek function-name contract (64 chars, `[A-Za-z0-9_-]`); when replacement or truncation changes the name, a deterministic 12-hex-char hash of `(serverName, rawName)` is appended so distinct tools never collapse into one name. Names are pure functions of `(serverName, rawName)` — connection order, re-syncs, and other servers never rename a tool.
+The model sees each tool under a stable server-qualified name: `mcp__<serverName>__<rawName>`, for example `mcp__github__create_issue` — the same naming shape Claude Code and Codex use. Names stay stable while the server keeps the same tool name, so session history and permission rules survive restarts and reloads. Two servers can both offer a tool named `search` and coexist as `mcp__github__search` and `mcp__web__search`.
 
-- Two servers publishing the same raw name (e.g. `search`) coexist under their namespaces.
-- A duplicate `serverName` inside one live registration scope fails the later plugin instance at load. Independent Agent scopes may reuse the same namespace because their tools and transports are isolated.
-- A server listing the same tool name twice is rejected as an invalid tool list.
-- A foreign registration squatting on this server's namespace rolls back the whole generation (never a partial set), with a loud error.
+- Two servers publishing the same tool name (for example `search`) coexist under their own namespaces.
+- Two entries using the same server name: the later one fails to load with a clear error.
+- A server that lists the same tool twice gets its tool list rejected as invalid, and the previous tool set stays active.
+- An update that conflicts with an already-registered tool name is rejected entirely — you never get a partial tool set from that server.
 
-## Behavior
+### Calling tools and reading results
 
-- On connect: plugin activation awaits `listTools()` and registers each tool via `ctx.tools.register()` under its public name before the composition starts its first turn. Initial connection, discovery, or registration failure is always logged; it rejects activation when `failOnStartupError` is true and otherwise activates with no tools.
-- Listens for `notifications/tools/list_changed` → re-syncs; a fetch-phase failure keeps the previous generation registered, while a registration conflict rolls back the attempted generation and leaves no tools from that server.
-- Tool execute: `client.callTool({ name: rawName, arguments }, { signal })` with timeout + abort support—the public name is never sent to the server.
-- Canonical success is `{ content: JsonValue[], structuredContent? }`; complete JSON MCP blocks survive for programmatic callers. A supported advertised `outputSchema` validates `structuredContent`; unsupported schema vocabulary falls back to unconstrained `JsonValue`.
-- Native/model rendering preserves MCP block order. Text-like runs join with newlines; resource links keep their name and URI as text; supported images become durable core image blocks only when `ctx.attachments` is mounted and the exact calling model route explicitly declares image input. The whole image batch is decoded and admitted before any member is saved. A malformed/refused image batch, audio, embedded resources, and unsupported blocks become explicit diagnostic text rather than disappearing.
-- On disconnect/crash: the supervisor restarts the original server config with exponential backoff (`reconnect.initialDelayMs` doubling up to `reconnect.maxDelayMs`) and re-runs discovery on success — the recovered generation replaces the previous one, so tools neither duplicate nor leak. During the outage the last good generation stays registered; calls against it fail until recovery.
-- Reconnection is budgeted per outage: after `reconnect.maxAttempts` consecutive failures the server's tools are unregistered and reconnection stops until an HMR reload or Host restart. A connection that survives past `maxDelayMs` resets the budget, so an occasionally-crashing server recovers indefinitely while a crash-looping one — even with briefly successful connects — still exhausts the cap instead of restarting forever.
-- Reconnect states are user-visible in logs: reconnecting (warn, with attempt count and delay), recovered (info), final failure and disabled-loss (error). Disposal cancels any pending reconnect. With `reconnect.enabled: false`, a lost connection keeps tools registered but failing until a reload — the manual-recovery behavior.
+When the model calls an MCP tool, the call runs against the remote server with a per-call timeout (default 60 seconds) and can be cancelled like any other tool call. The result comes back as ordinary text in block order; resource links appear as text with their name and URI. If the server reports an error, the call fails visibly — the model does not see a fake success.
 
-## Services consumed
+Images are supported when the current model accepts image input and the harness attachment feature is enabled; they then appear in the conversation like other images. Otherwise — and for audio or embedded resources — the model sees a clear diagnostic message instead of nothing.
 
-| Service | Usage |
+### Startup, updates, and reconnection
+
+The server's tools appear before the harness starts its first turn. When the server changes its tool list, the model's tool set updates automatically; if the update fails, the previous tool set keeps working.
+
+When a server connection drops — for example a local server process crashes — the plugin reconnects automatically with delays that double from 500 ms up to 30 s and then refreshes the tool set; reconnect progress is visible in the logs. During an outage the last known tools stay listed but calls to them fail until the server recovers. After ten consecutive failed attempts the server's tools are removed and reconnection stops until you reload the configuration or restart the harness; a server that stays connected for a while resets that counter. Set `reconnect.enabled: false` to disable automatic reconnection — tools then stay listed but fail until you reload. Editing the configuration entry reloads the server connection in place, and unchanged names stay unchanged.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the bridge and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+- **Server-qualified identity.** Every MCP tool has the stable identity `(serverName, rawName)`. The namespace is local configuration, never the remote `serverInfo.name` — the remote name is untrusted, not unique across deployments, and can change on upgrade, none of which may silently rename model-facing tools.
+- **Naming is a pinned contract.** Public names are pure functions of `(serverName, rawName)` and satisfy the DeepSeek function-name contract; lossy normalization appends a 12-hex-char SHA-256 hash so distinct identities never collapse. Session history and permission rules therefore survive HMR swaps, re-syncs, and other servers' changes.
+- **The raw name is the only wire name.** `tools/call` always receives the raw name; the public name is never sent to the server and never parsed to recover the raw name.
+- **Full generation or none.** Syncs swap generations atomically: a fetch failure keeps the previous generation, and a registration conflict rolls back the entire attempted generation.
+- **One canonical value, one projection.** The executor returns the protocol-complete canonical `McpResult`; a separate ordered projection prepares Native content, and `finalizeContent` installs it only when the registry's post-execute result is unchanged, so policy blocks and value replacements stay authoritative.
+
+### Source map
+
+| File | Role |
 |---|---|
-| `ctx.tools` | Register/unregister MCP tools |
-| `ctx.attachments` | Optionally validate and persist image result batches before model projection |
-| `ctx.llm` | Optionally prove the exact calling route explicitly supports image input |
+| [`src/index.ts`](src/index.ts) | Plugin entry: `Config` schema, `serverName` reservation, activation await |
+| [`src/connection.ts`](src/connection.ts) | Connection supervisor: client generations, reconnect policy, attempt budget, disposal |
+| [`src/tools.ts`](src/tools.ts) | Tool bridge: discovery, naming, registration swap, execution, image projection |
+| [`src/transport.ts`](src/transport.ts) | Transport factory: stdio spawn with scrubbed env, Streamable HTTP |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; generations are observable only through the tool registry) |
 
+### Lifecycle and sync
+
+`apply` resolves the reconnect policy, reserves the `serverName` inside the current registration scope, starts the supervisor, and awaits the initial connection plus discovery. Independent Agent scopes may reuse the same namespace because their tools and transports are isolated; a duplicate inside one scope fails at load. The supervisor serializes every sync — initial, notification, and reconnect — through one queue so two syncs can never interleave their dispose-previous/register-next swap. Disposal cancels pending reconnects, closes the live client, waits for the in-flight attempt and queued syncs to quiesce, and unregisters the current generation. The [auto-reconnect Agent Note](../../../.agents/notes/implemented/feature/2026-08-06-mcp-client-auto-reconnect.md) owns the reconnect decision.
+
+The supervisor listens for `notifications/tools/list_changed` and queues a re-sync; a fetch-phase failure keeps the previous generation registered, while a registration conflict rolls back the attempted generation. Each outage shares one attempt budget: after `maxAttempts` consecutive failures the tools are unregistered and reconnection stops, and a connection that stays up past `maxDelayMs` resets the budget.
+
+### Tool execution internals
+
+A tool call sends an uncached `tools/call` request carrying the raw MCP name, the JSON arguments, the abort signal, and the configured timeout; the public name is never sent to the server and never parsed back. Canonical success is `{ content: JsonValue[], structuredContent? }`, preserving the complete MCP JSON blocks for programmatic and Code Mode callers. A supported advertised `outputSchema` validates `structuredContent`; unsupported schema vocabulary falls back to unconstrained `JsonValue`. An MCP `isError` result throws before any image persistence, so the registry produces a failed tool result. Image batches are decoded and validated as a whole before any member is saved; any refusal projects every image as diagnostic text.
+
+### Environment scrubbing (stdio)
+
+The child environment starts from the subprocess seam's `scrubbedParentEnv()` — ambient names matching `/KEY|PASSWORD|SECRET|TOKEN/i` and ambient `DSH_*` names are dropped — and the configured `env` merges on top, so explicit overrides survive. The MCP SDK owns the actual spawn; this package shares the scrub definition, not the spawn path.

 ### Discovered MCP tools
 
 #### What the model sees
 
-After initial discovery succeeds, each advertised MCP tool appears as a native tool named `mcp__<serverName>__<rawName>` (or its deterministic normalized form), with the server-provided description and input schema. A successful re-sync — including the one after an automatic reconnect — replaces the generation; plugin disposal or an exhausted reconnect budget removes it.

 #### Token effect

 ### Tool-call history and results
 
 #### What the model sees
 
-The public tool name and JSON arguments remain in assistant history. The execution-local canonical value always retains the complete JSON MCP blocks and optional structured content for programmatic and Code Mode callers. In Native context, supported image blocks are durably projected beside text in their original order after exact route-capability proof; Code Mode additionally ferries that settled rich projection through the outer `run_code` result without changing the canonical binding value. Refused images, audio, embedded resources, resource links, and unknown blocks remain visible as bounded text diagnostics, and MCP `isError` rejects the call before image persistence.

 ## Known Limitations and Deferred Work
 
-- **Tools are the only bridged MCP capability** — Resources and Prompts have no harness consumer and are deferred.
-- **Startup timeout is inherited from the MCP SDK** — DSH does not yet expose a connection/discovery timeout. Each initialize or paginated `tools/list` request uses the SDK's 60-second default, so an unresponsive server or cursor chain can delay both activation and teardown while the initial synchronization settles.
-- **Reconnect triggers on transport close** — a crashed stdio child fires it; Streamable HTTP failures surface per request and through the SDK transport's own SSE-stream recovery, so an unreachable HTTP server is retried per call rather than respawned by the supervisor.
-- **Image is the only durable rich-result bridge** — PNG, JPEG, WebP, and GIF can enter Native context after exact capability proof. Audio and embedded-resource payloads remain execution-local with explicit diagnostics, while resource links preserve only their name and URI as text.

+- The public-name algorithm is a v1 contract pinned by tests; changing it after release would break session history and permission rules.
+- An explicit DSH-owned connection and discovery timeout is an open direction; the SDK's 60-second default bounds startup and teardown.
+- Reconnect ownership for Streamable HTTP is open: per-request retry is SDK behavior, and the supervisor could also own the HTTP generation.

-MCP 客户端桥接插件：连接外部 [Model Context Protocol](https://modelcontextprotocol.io/) 服务器，把它们的工具注册到 `ctx.tools`，使模型能够通过服务器限定名称（`mcp__<serverName>__<rawName>`）将其作为原生工具使用。
+## 概述
 
-## 用法
+`dsh-mcp-client` 把外部 MCP（Model Context Protocol）服务器挂载到 harness 上，让它们的工具像原生工具一样可用。每台服务器一条配置项，模型就能调用该服务器的工具——文件系统、GitHub、数据库或记忆服务器——名称稳定，例如 `mcp__github__create_issue`。当模型需要使用外部工具服务器时添加它；默认不启用任何服务器，因此由你开启。主要成本是这些工具定义给每次请求增加的 token，而且缓慢或崩溃的服务器可能延迟启动，或在恢复前让它的工具一直调用失败。只桥接工具能力：MCP resources 与 prompts 不受支持。
 
-`cordis.yml` 中每个 MCP 服务器使用一个插件实例：

+## 使用本包
+
+当模型需要把外部 MCP 服务器的工具当作原生工具调用时，添加 `dsh-mcp-client`。每台服务器一条配置项就是全部设置：给服务器一个简短的唯一名称和一种传输方式，它的工具就会以 `mcp__<serverName>__<tool>` 形式出现。服务器作为本地程序运行时选择 stdio，作为服务运行时选择 Streamable HTTP。如果你已经用其他客户端连接过 MCP 工具服务器，同样的配置行在这里也能用。
+
+### 最小配置
+
+每台服务器添加一条配置项即可，无需其他内容。harness 启动后，服务器的工具会出现在模型的工具列表中。

+启动后，服务器的工具会以 `mcp__<serverName>__<tool>` 形式出现——试着用一条提示词调用其中一个。如果初始连接失败，harness 仍会启动，但该服务器的工具不会出现，并会记录一条错误；设置 `failOnStartupError: true` 可让启动失败改为中止 harness。
 
-## 工具命名
+### 工具命名与共存
 
-每个 MCP 工具都有两个名称：通过 `tools/call` 在协议上传送的原始 MCP 名称，以及公开名称 `mcp__<serverName>__<rawName>`，后者注册到 `ctx.tools`。公开名称会规范化为 DeepSeek 函数名称约定（64 个字符、`[A-Za-z0-9_-]`）；如果替换或截断改变名称，就会追加 `(serverName, rawName)` 的确定性 12 位十六进制 hash，确保不同工具绝不会折叠为同一个名称。名称是 `(serverName, rawName)` 的纯函数：连接顺序、重新同步和其他服务器永远不会重命名工具。
+模型看到每个工具都带有稳定的服务器限定名称：`mcp__<serverName>__<rawName>`，例如 `mcp__github__create_issue`——与 Claude Code 和 Codex 使用的命名形态相同。只要服务器保持相同的工具名称，名称就保持不变，因此会话历史与权限规则在重启和重载后仍然有效。两个服务器可以同时提供名为 `search` 的工具，分别以 `mcp__github__search` 和 `mcp__web__search` 共存。
 
-- 发布相同原始名称（例如 `search`）的两个服务器会在各自 namespace 下共存。
-- 同一个存活 registration scope 内重复的 `serverName` 会使后加载的插件实例失败。独立 Agent scope 的工具和传输彼此隔离，因此可以复用同一 namespace。
-- 服务器在工具列表中两次列出同一工具名称时，该列表会作为无效工具列表被拒绝。
-- 外部注册抢占该服务器 namespace 时，会回滚整个世代（绝不保留部分集合），并明确报错。
+- 发布相同工具名称（例如 `search`）的两个服务器会在各自的 namespace 下共存。
+- 两条配置项使用相同的服务器名称时，后加载的一条会在加载时以明确错误失败。
+- 服务器在工具列表中两次列出同一工具时，其工具列表会被作为无效列表拒绝，上一组工具保持可用。

-## 行为
+### 调用工具与读取结果
 
-- 连接时：插件激活会等待 `listTools()`，并在组合开始首个轮次前通过 `ctx.tools.register()` 以公开名称注册每个工具。初始连接、发现或注册失败始终会记录日志；`failOnStartupError` 为 true 时拒绝激活，否则插件仍会激活但不注册工具。
-- 监听 `notifications/tools/list_changed` → 重新同步；获取阶段失败时保留上一世代的注册，注册冲突则会回滚本次尝试的世代，并且不保留该服务器的任何工具。
-- 工具执行：`client.callTool({ name: rawName, arguments }, { signal })`，支持超时 + 中止；公开名称绝不会发给服务器。
-- 规范成功值是 `{ content: JsonValue[], structuredContent? }`；完整的 JSON MCP 块会保留给编程调用方。受支持且已声明的 `outputSchema` 会验证 `structuredContent`；不受支持的 schema 词汇会回退为不受约束的 `JsonValue`。
-- Native／模型渲染会保留 MCP 块顺序。文本类连续块以换行连接；资源链接以文本保留名称和 URI；只有挂载 `ctx.attachments` 且确切调用模型路由明确声明支持图片输入时，受支持的图片才会成为持久核心图片块。整个图片批次会先完成解码与准入，再保存任一成员。格式错误或被拒绝的图片批次、音频、嵌入资源和不受支持的块会成为明确诊断文本，而不会消失。
-- 断开／崩溃时：supervisor 以指数退避（`reconnect.initialDelayMs` 逐次翻倍，上限 `reconnect.maxDelayMs`）重启原始服务器配置，成功后重新执行发现——恢复的世代会替换前一个，因此工具既不会重复也不会泄漏。中断期间最后一个正常世代保持注册；针对它的调用在恢复前会失败。
-- 重连按中断预算控制：连续失败达到 `reconnect.maxAttempts` 次后，该服务器的工具会被注销，重连停止，直到 HMR 重载或重启 Host。连接存活超过 `maxDelayMs` 会重置预算，因此偶尔崩溃的服务器可以无限恢复，而崩溃循环的服务器——即使短暂连接成功——仍会耗尽上限而非永远重启。
-- 重连状态在日志中对用户可见：reconnecting（warn，含尝试次数和延迟）、recovered（info）、最终失败和 disabled-loss（error）。dispose（资源释放）会取消任何待执行的重连。设置 `reconnect.enabled: false` 时，连接丢失后工具保持注册但调用失败，直到重载——即手动恢复行为。
+模型调用 MCP 工具时，调用会以每次调用超时（默认 60 秒）发往远程服务器，并像其他工具调用一样可以取消。结果按块顺序以普通文本返回；资源链接以文本形式显示名称与 URI。如果服务器报告错误，调用会明确失败——模型不会看到虚假的成功。
 
-## 消费的服务
+当前模型接受图片输入且 harness 启用了附件功能时支持图片；图片会像其他图片一样出现在对话中。不支持图片时——以及服务器返回音频或嵌入资源时——模型会看到清晰的诊断消息，而不是什么都没有。
 
-| 服务 | 用途 |
+### 启动、工具更新与重连
+
+服务器的工具会在 harness 开始首个轮次之前出现。服务器更改工具列表时，模型的工具集会自动更新；更新失败时，上一组工具继续可用。
+
+服务器连接断开时——例如本地服务器进程崩溃——插件会以从 500 ms 起逐次翻倍、上限 30 s 的延迟自动重连，并刷新工具集；重连进度在日志中可见。中断期间最后已知的工具仍会列出，但对它们的调用会失败，直到服务器恢复。连续失败十次后，该服务器的工具会被移除，重连停止，直到你重载配置或重启 harness；服务器持续连接一段时间后，该计数会重置。设置 `reconnect.enabled: false` 可禁用自动重连——此时工具在断开后仍会列出，但调用失败，直到你重载。编辑配置项会在原地重载服务器连接，未变的名称保持不变。

+
+本节解释桥接背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+- **服务器限定身份。** 每个 MCP 工具都有稳定的身份 `(serverName, rawName)`。namespace 是本地配置，绝不采用远程 `serverInfo.name`——远程名称不可信、在部署间不唯一、且升级时可能变化，这些都不允许静默重命名面向模型的工具。
+- **命名是固定约定。** 公开名称是 `(serverName, rawName)` 的纯函数，并满足 DeepSeek 函数名称约定；有损规范化会追加 12 位十六进制 SHA-256 hash，使不同身份绝不会折叠。会话历史与权限规则因此能在 HMR 替换、重新同步和其他服务器变化后保持有效。
+- **原始名称是唯一的协议名称。** `tools/call` 始终收到原始名称；公开名称绝不会发给服务器，也绝不会被解析来还原原始名称。
+- **要么完整世代，要么没有。** 同步会原子地交换世代：获取失败保留上一世代，注册冲突则回滚整个尝试中的世代。
+- **一个规范值，一个投影。** 执行器返回协议完整的规范 `McpResult`；另一个有序投影准备 Native 内容，`finalizeContent` 只在注册表的执行后结果未变时安装它，因此策略块与值替换保持权威。

+### 生命周期与同步
+
+`apply` 解析重连策略、在当前注册作用域内预留 `serverName`、启动监督器，并等待初始连接加发现完成。独立 Agent 作用域可以复用相同 namespace，因为其工具与传输彼此隔离；同一作用域内重复会在加载时失败。监督器把所有同步——初始、通知与重连——串行到同一条队列，因此两次同步绝不会交错执行各自的先 dispose 后注册交换。dispose 会取消待执行的重连、关闭活动客户端、等待进行中的尝试与排队同步完全停稳，然后注销当前世代。[自动重连 Agent Note](../../../.agents/notes/implemented/feature/2026-08-06-mcp-client-auto-reconnect.zh.md) 拥有重连决策。
+
+监督器监听 `notifications/tools/list_changed` 并排队一次重新同步；获取阶段失败时保留上一世代注册，注册冲突则回滚本次尝试的世代。每次中断共享一个尝试预算：连续失败达到 `maxAttempts` 次后工具被注销、重连停止；连接存活超过 `maxDelayMs` 会重置预算。
+
+### 工具执行内部细节
+
+工具调用会发送一次未缓存的 `tools/call` 请求，携带原始 MCP 名称、JSON 参数、中止信号与配置的超时；公开名称绝不会发给服务器，也绝不会被解析还原。规范成功值是 `{ content: JsonValue[], structuredContent? }`，为程序化调用方与 Code Mode 调用方保留完整的 MCP JSON 块。受支持且已声明的 `outputSchema` 会验证 `structuredContent`；不受支持的 schema 词汇回退为不受约束的 `JsonValue`。MCP 的 `isError` 结果会在任何图片持久化之前抛出，使注册表产生失败的工具结果。图片批次会先整体解码并校验，再保存任一成员；任何拒绝都会把每张图片投影为诊断文本。
+
+### 环境清洗（stdio）
+
+子进程环境以子进程 seam 的 `scrubbedParentEnv()` 为基座——删除匹配 `/KEY|PASSWORD|SECRET|TOKEN/i` 的环境名称与所有 `DSH_*` 名称——再在其上合并配置的 `env`，因此显式覆盖得以保留。实际 spawn 由 MCP SDK 负责；本包共享清洗定义，而非 spawn 路径。

 # plan/ — plan collaboration state
 
 English | [中文](README.zh.md)
 
-Plan mode is logged, per-agent collaboration state rather than a generic mode registry or capability seam.
+## Summary
+
+The `plan/` group provides plan mode: while it is active, the agent explores and designs before executing, guided by instructions the deployment writes, and presents the finished plan for your approval before carrying it out. You can enter and leave plan mode with the `/plan` command and approve the plan or send the agent back to keep planning. Plan mode guides rather than restricts: every tool stays available, and limits such as sandbox mode and approval prompts are configured separately. The group contains one package, `plan-mode`.

 English | [中文](README.zh.md)
 
-Logged, per-agent plan collaboration state with deployment-owned guidance, direct `/plan [message]` entry and `/plan off` exit commands, and the reviewed `exit_plan_mode` exit. Plan mode is soft guidance; sandbox mode and approval policy enforce restrictions independently and do not read or write plan state.
+## Summary
 
-## Durable state
+`dsh-plan-mode` adds plan mode to the agent: while it is active, the agent explores and designs before executing, guided by instructions the deployment writes, and presents the finished plan for your approval before carrying it out. You enter plan mode with `/plan` (optionally with a message or images) and leave it with `/plan off`; the finished plan arrives as a review where you can approve it or send the agent back to keep planning. Plan mode is guidance, not enforcement: every tool stays available, so sandbox mode and approval prompts remain the way to impose limits. Choose it when the agent should think before acting, and plan mode carries over when a session resumes or forks.
 
-`plan/mode` (`{ active: boolean }`) is a log-only, whole-value-replace `SessionEventMap` member. `foldPlanMode(events)` returns the last logged value or `false`, so resume, fork, and compaction recover plan state directly from the session log. UIs observe committed flips through `session/event`.
+## Table of Contents
 
-`ctx.planMode.set(agent, active)` appends the standalone `plan/mode` event immediately when the agent is idle, because no in-turn pre-step runs before the next prompt. While the agent is running, it holds a pending selection for the next accepted in-turn pre-step. It returns which happened (`committed`/`queued`), a `cancelled` reversal, or a `noop`. `get(agent)` returns `{ active, pending? }`, separating the logged state used to assemble the current step from a user's mid-turn selection. Initial and continuation pre-steps both apply pending selections; a same-step request-recovery retry reuses its frozen assembly and leaves the selection pending for the next pre-step. A changed user selection contributes one plugin-sourced `user/message` notice when the last logged request header described the other state (both commit paths).

-## Model and human interactions
+-----
 
-While active, `plan:policy` renders the configured `section`. The plugin always registers `exit_plan_mode`, keeping tool schemas stable across the transition; its execute path accepts only active plan mode and leaves it only after an exact user approval through `ctx.userQuestions`.
+<a id="use-this-package"></a>
+## Use this package
 
-The review question declares the `plan-review` presentation intent, naming `Approve` as the label that approves it, so a capable UI presents the plan as a decision instead of a generic question; the answer the tool reads is the same either way. A dismissed review — the user closing the request to speak instead — is reported to the model as such, telling it to stay in plan mode and wait for the message; every other review failure keeps the seam's own message.
+When plan mode is active, the agent works under your instructions and presents its plan for review instead of executing right away. The common path: configure the guidance text, enter plan mode with `/plan`, and review the finished plan when the agent calls `exit_plan_mode`.
 
-When `ctx.commands` is composed, the package registers `/plan [message]` and reserves the exact argument `off` for direct exit. Bare `/plan` selects plan mode; any other non-empty argument selects it first and is then submitted through `agent.steer()`, so it becomes the next step's ordinary logged user message under plan guidance. `/plan off` selects inactive without sending model input; it also cancels a pending entry before plan mode reaches a request. The command declares `input.images`: composer image attachments ride the steered message ahead of its text block. Bare `/plan` with images steers an image-only user message, while `/plan off` with images returns a direct error before any mode change so the composer keeps them.
+### When to choose it
 
-The Web client consumes the plugin-owned `/plan` command; other entry points may drive the same service directly without defining a second mode vocabulary.
+Choose plan mode when the agent should explore and design before executing and you want to approve the plan first. It does not restrict the agent: every tool stays callable, so use sandbox mode and approval prompts when you need enforced limits. Skip it when the agent should act on your requests immediately, without a planning phase.
 
-## Session projection
+### Minimal configuration
 
-When the composition mounts `ctx.sessionProjections` ([`@deepseek-ai/dsh-session-projection`](../../session/session-projection/README.md)), this package registers the `plan` projection unit under an injected child. A `command/run` record named `plan` with recorded `args` starts a candidate target (`off` → inactive, anything else → active); its paired `command/done` retains a successful selection and drops an error; `plan/mode` commits the logged state and clears the retained selection. Every other event returns the same state reference. `view` derives `{ active, pending }`, where `pending` is true only while an unsettled or successful selection differs from the logged state. This remains a pure replay quantity, so host restarts, other tabs, and cold reads recover it from the log alone, and a rejected `/plan off` with images cannot leave a pending exit. The key merges into `SessionProjectionMap` from `src/types.ts` (served to host consumers via `./types` and client aggregates via `./client`); the framework drives the unit and carriers serve the value on the history tail page and the `session/projection` push frame. Compositions without the registry are unaffected.
-
-## Configuration
+The only required configuration is the guidance text the agent follows while planning; anything else you add fails at load.
 
 ```yaml
-- id: plan-mode
-  name: '@deepseek-ai/dsh-plan-mode'
+- name: '@deepseek-ai/dsh-plan-mode'
   config:
     section: |
       You are in plan mode. Explore and design before presenting the complete
       plan through exit_plan_mode.
 ```
 
-`section` is required and non-empty. Unknown keys fail at load. The package does not accept arbitrary named modes, tool filters, sandbox settings, or approval policy.
+| Field | Default | Meaning |
+|---|---|---|
+| `section` | required | Guidance rendered as the `plan:policy` prompt section while plan mode is active |
 
-Design: [plan-specific collaboration state](../../../.agents/notes/implemented/simplification/2026-07-22-plan-specific-collaboration-state.md).
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-plan-mode) is the exhaustive source for every accepted field and its JSDoc.
 
+<a id="model-and-human-interactions"></a>
+### Entering and leaving plan mode
+
+Type `/plan` to enter plan mode, or `/plan <message>` to enter with an instruction — the message becomes your next request under plan guidance. Type `/plan off` to leave plan mode directly; it also cancels a plan-mode entry that has not taken effect yet.
+
+You can attach images to a `/plan` message, and they are included with your instruction. `/plan off` with images is rejected so the images are not lost. The `/plan` command is available wherever slash commands are supported, such as the Web client.
+
+### The reviewed exit
+
+When the agent has a finished plan, it calls `exit_plan_mode` with the plan written as markdown and starting with a heading. You review that exact plan and choose `Approve` to leave plan mode, or `Keep planning` to send the agent back with feedback.
+
+Choosing `Keep planning` (optionally with free-text feedback) sends the agent back to revise the plan; closing the review to type a message instead tells the agent to wait for your next message. If no interactive review is available, `exit_plan_mode` cannot run and you can still leave plan mode with `/plan off`.
+
+### Observing plan state
+
+Interfaces can show whether plan mode is active and whether a mode change you requested is still waiting to take effect. The state is the same in every tab and survives restarts.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the package and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+Plan mode is a product package, not a capability seam: there is no swappable backend, so the state, guidance, command, and exit tool live in one place. The durable stance is one log-only whole-value-replace event, never a live mirror, so resume, fork, and compaction recover it by folding the log. Guidance is a soft layer — the package registers one prompt section and one tool, and restrains through text rather than filtering capabilities.
+
+### Durable state and step-boundary appends
+
+The package persists one log-only whole-value event, `plan/mode`, and the last logged value is the state. A mode change appends immediately when no turn is open; during an open turn it stays pending until the next accepted in-turn pre-step — the only append point while an agent runs — and an append failure cannot block the turn. The `set`/`get`/`foldPlanMode` helpers and their exact return states live in [`src/index.ts`](src/index.ts).
+
+### The `/plan` command
+
+The command child activates only when a commands service is composed. It maps bare `/plan` to active, the exact argument `off` to inactive without model input, and any other non-empty argument to active plus the trimmed text submitted through `agent.steer()` as the next step's ordinary logged user message; image attachments ride the steered message, and `/plan off` with images fails before any mode change. Entry points other than the command may drive `ctx.planMode` directly; the exact branch handling is in [`src/index.ts`](src/index.ts).
+
+### The exit tool
+
+`exit_plan_mode` stays registered while plan mode is inactive, so entering or leaving changes only the prompt section, never the request tool catalog. An approved review records a silent pending exit that the next accepted in-turn pre-step appends, keeping plan guidance for the rest of the current tool batch. Without a user-questions channel, or after a service reload while the review is pending, the call fails closed and `/plan off` remains the manual escape.
+
+### Session projection unit
+
+When `ctx.sessionProjections` is composed, the package registers the `plan` unit under an injected child. The unit turns logged `/plan` command runs into a candidate target, commits the logged state on `plan/mode`, and derives `{ active, pending }` for `view`, where `pending` is true only while an unsettled or successful selection differs from the logged state — a pure replay quantity recoverable from the log alone. The key merges into `SessionProjectionMap` from [`src/types.ts`](src/types.ts); the framework drives the unit, and unloading the plugin fiber unregisters the key.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `Config` schema, the `ctx.planMode` service, `plan:policy` section, `/plan` command, `exit_plan_mode` tool |

+## 概述
 
-## 持久状态
+`dsh-plan-mode` 为 agent（智能体）提供计划模式：激活期间，agent 先探索和设计再执行，遵循你的部署所写的引导行事，并在执行前把完成的计划呈交你批准。你可以用 `/plan`（可附带消息或图片）进入计划模式，用 `/plan off` 离开；完成的计划会以评审形式呈现，你可以批准它，或让 agent 回去继续规划。计划模式是引导而非强制：每个工具仍然可用，因此沙箱模式与审批提示仍是施加限制的方式。当希望 agent 先思考再行动时选择它；会话恢复或 fork 后计划模式依然保持。
 
-`plan/mode`（`{ active: boolean }`）是一个仅存在于日志中、每次以完整值替换的 `SessionEventMap` 成员。`foldPlanMode(events)` 返回最后记录的值，如果没有则返回 `false`，因此恢复、fork 和压缩（compaction）都能直接从会话日志恢复 plan 状态。UI 通过 `session/event` 观察已提交的切换。
+## 目录
 
-`ctx.planMode.set(agent, active)` 会在 agent 空闲时立即追加独立的 `plan/mode` 事件，因为下一个提示词之前不会运行轮内 pre-step。agent 运行时，该方法会保留待生效选择，直到下一个被接受的轮内 pre-step。返回值区分 `committed`、`queued`、表示反转的 `cancelled` 和 `noop`。`get(agent)` 返回 `{ active, pending? }`，将用于组装当前步骤的日志状态与用户的轮中选择分开。初始与续步 pre-step 都会应用待生效选择；同一步骤的请求恢复重试会复用已冻结的 assembly，并将该选择保留到下一个被接受的轮内 pre-step。当最后记录的请求头描述了另一状态时，用户选择的变更会贡献一条插件来源的 `user/message` 通知（两条提交路径皆然）。

+计划模式激活时，agent 会按你的指令行事，并先呈交计划供评审，而不是立即执行。常用路径：配置引导文本，用 `/plan` 进入计划模式，agent 调用 `exit_plan_mode` 时评审完成的计划。
 
-评审问题声明 `plan-review` 呈现意图，并指名 `Approve` 为表示批准的标签，因此有能力的 UI 会把计划呈现为一次决定而非通用问题；两种情况下该工具读到的回答完全相同。放弃审阅——用户关闭请求，转而发言——会如实报告给模型，要求它留在 plan mode 中等待那条消息；其余每一种评审失败都保留 seam 自身的消息。
+### 何时选择
 
-组合 `ctx.commands` 时，该包会注册 `/plan [message]`，并将参数恰好为 `off` 的情况保留给直接退出。不带参数的 `/plan` 会启用 plan mode；任何其他非空参数都会先启用 plan mode，再通过 `agent.steer()` 提交，因此它会在 plan 引导下成为下一步骤的常规已记录用户消息。`/plan off` 会选择停用状态，不发送模型输入；它还可以在启用 plan mode 的待处理选择由轮内 pre-step 追加之前将其取消。该命令声明了 `input.images`：composer 图片附件会随被 steer 的消息一起提交，位于文本块之前。不带参数的 `/plan` 若附有图片，会 steer 一条只含图片的用户消息；`/plan off` 若附有图片，会在任何模式变更前直接返回错误，composer 保留图片。
+当希望 agent 先探索和设计再执行、并且想先批准计划时，选择计划模式。它不限制 agent：每个工具仍可调用，因此需要强制限制时请使用沙箱模式与审批提示。当 agent 应立即按你的请求行事、无需规划阶段时，跳过它。
 
-Web 客户端使用该插件提供的 `/plan` 命令；其他入口可以直接驱动同一服务，无需定义第二套 mode 词汇。
+### 最小配置
 
-## 会话投影
-
-当组合挂载 `ctx.sessionProjections`（[`@deepseek-ai/dsh-session-projection`](../../session/session-projection/README.zh.md)）时，本包会在一个注入的子插件中注册 `plan` 投影单元。名为 `plan` 且携带已记录 `args` 的 `command/run` 记录会开始一个候选目标（`off` → 未激活，其余 → 激活）；与它配对的 `command/done` 保留成功选择并丢弃错误选择；`plan/mode` 提交已记录状态并清除已保留的选择。其他任何事件都返回同一个状态引用。`view` 推导 `{ active, pending }`，其中 `pending` 仅在未结算或已成功的选择与已记录状态不同时为 true。该值仍完全由日志回放得出，因此 host 重启、其他标签页和冷读都能仅凭日志恢复它，被拒绝的带图 `/plan off` 也不会留下待退出状态。key 由 `src/types.ts` 通过声明合并加入 `SessionProjectionMap`：host 消费方经 `./types` 获取，client 聚合经 `./client` 获取。框架负责驱动该单元，载体通过历史尾页和 `session/projection` 推送帧提供其值。未挂载注册表的组合不受影响。
-
-## 配置
+唯一必需的配置是 agent 规划期间遵循的引导文本；添加任何其他内容都会在加载时失败。
 
 ```yaml
-- id: plan-mode
-  name: '@deepseek-ai/dsh-plan-mode'
+- name: '@deepseek-ai/dsh-plan-mode'
   config:
     section: |
       You are in plan mode. Explore and design before presenting the complete
       plan through exit_plan_mode.
 ```
 
-`section` 必填且非空。出现未知键时，插件会加载失败。该包不接受任意命名的 mode、工具过滤器、沙箱设置或批准策略。

+<a id="model-and-human-interactions"></a>
+### 进入与离开计划模式
+
+输入 `/plan` 进入计划模式，或输入 `/plan <message>` 连同一条指令一起进入——该消息会成为你在计划引导下的下一条请求。输入 `/plan off` 直接离开计划模式；它还会取消尚未生效的计划模式进入。
+
+你可以在 `/plan` 消息中附带图片，图片会随你的指令一起提交。带图片的 `/plan off` 会被拒绝，因此图片不会丢失。`/plan` 命令在支持斜杠命令的界面中可用，例如 Web 客户端。
+
+### 经评审的退出
+
+agent 完成计划后，会以 markdown 形式、从标题开头书写计划并调用 `exit_plan_mode`。你评审该计划的原文，选择 `Approve` 离开计划模式，或选择 `Keep planning` 带反馈把 agent 送回去。
+
+选择 `Keep planning`（可附自由文本反馈）会让 agent 回去修订计划；关闭评审改为发言，则告知 agent 等待你的下一条消息。若没有可用的交互评审，`exit_plan_mode` 无法运行，你仍可用 `/plan off` 离开计划模式。
+
+### 观察计划状态
+
+界面可以显示计划模式是否激活，以及你请求的模式变更是否仍在等待生效。该状态在每个标签页中一致，并能在重启后保留。

+## 理解实现
+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释本包背后的设计决策并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+计划模式是产品包，而不是能力 seam：没有可替换的后端，因此状态、引导、命令与退出工具都集中在一处。持久姿态是单一仅记日志、整值替换的事件，绝不是实时镜像，因此恢复、fork 与压缩（compaction）都通过折叠日志复原它。引导是软性层——本包注册一个提示词段落和一个工具，通过文本而非过滤能力来约束。
+
+### 持久状态与步骤边界追加
+
+本包持久化一条仅记日志、整值替换的事件 `plan/mode`，最后一条已记录值即为状态。没有轮次开启时，模式变更会立即追加；轮次开启期间，它保持待生效，直到下一个被接受的轮内 pre-step——agent 运行时唯一的追加点——且追加失败不能阻塞轮次。`set`/`get`/`foldPlanMode` 辅助函数及其确切返回状态见 [`src/index.ts`](src/index.ts)。
+
+### `/plan` 命令
+
+命令子插件只在组合了命令服务时激活。它把不带参数的 `/plan` 映射为激活，把恰好为 `off` 的参数映射为未激活且不发送模型输入，把其他非空参数映射为激活并把去除首尾空白的文本通过 `agent.steer()` 作为下一步骤的普通已记录用户消息提交；图片附件随被 steer 的消息一起提交，带图片的 `/plan off` 会在任何模式变更前失败。命令以外的入口可以直接驱动 `ctx.planMode`；确切的分支处理见 [`src/index.ts`](src/index.ts)。
+
+### 退出工具
+
+`exit_plan_mode` 在计划模式未激活时仍保持注册，因此进入或离开只改变提示词段落，绝不改变请求的工具目录。经批准的评审会记录一个静默的待生效退出，由下一个被接受的轮内 pre-step 追加，当前这批工具调用剩余部分仍保留计划引导。缺少用户交互通道，或评审等待期间服务重载，调用都会失败关闭，`/plan off` 仍是手动退路。
+
+### 会话投影单元
+
+组合 `ctx.sessionProjections` 时，本包在一个注入的子插件中注册 `plan` 单元。该单元把已记录的 `/plan` 命令运行转为候选目标，在 `plan/mode` 上提交已记录状态，并为 `view` 推导 `{ active, pending }`，其中 `pending` 仅在未结算或已成功的选择与已记录状态不同时为 true——这是仅凭日志即可恢复的纯回放量。key 由 [`src/types.ts`](src/types.ts) 的声明合并加入 `SessionProjectionMap`；框架负责驱动该单元，卸载插件 fiber 会注销该 key。
+
+### 源码地图

-- Plan mode 只进行引导，而不强制执行；需要强制限制的部署必须分别配置沙箱与批准控制。
-- 如果进程在另一个被接受的轮内 pre-step 之前退出，某轮最后一个被接受的 pre-step 之后作出的选择会丢失，因此 UI 必须重新应用它。
-- Fork 的 agent 会继承已记录的 plan 状态，新 spawn 的 agent 则从未激活状态开始；不存在创建时 plan 选项。
-- 由另一个 agent 所有的存活子级无法打开 `exit_plan_mode` 审阅。该调用失败时会提示子级在最终结果中包含尚未解决的决策；仅有持久化 fork 谱系并不会阻止恢复为运行时根的会话打开该审阅。

-An **agent preset** is a directory holding one `agent.cordis.yml`. Mounting it under an agent's scope context gives that session its own tools and prompt sections while every other live session keeps its own, so one process can run several differently composed agents at once.
+## Summary
+
+The preset group provides per-session agent composition: an agent preset is a directory holding one `agent.cordis.yml`, and a session composed from a preset runs that preset's tools, prompt sections, and skills while every other session keeps its own. `agent-presets` owns the roster — discovery over configured roots plus the harness home, the guarded per-agent mount, and copy-only authoring — and `persona` supplies the composable row that lets a preset change an agent's identity and not only its tools. Together they let one process run several differently composed agents at once.

-The composition split this group assumes: registries and cross-session facilities are process singletons and stay in the host composition, while a preset carries what one agent contributes to them. A preset that names a row publishing a process-global service is rejected at mount rather than allowed to collide with the next session.

-**agent preset** 是一个目录，其中放置一份 `agent.cordis.yml`。把它挂载到某个 agent（智能体）的 scope 上下文之下，该会话就获得自己的工具与提示词段落，而其他在运行的会话各自保持不变，因此一个进程可以同时运行多个组装方式不同的 agent。
+## 概述
+
+preset 组提供按会话的 agent（智能体）组装：agent preset 是一个目录，内含一份 `agent.cordis.yml`；从 preset 组装的会话会运行该 preset 的工具、提示词段落与 skill（技能），而其他会话各自保持自己的。`agent-presets` 拥有名单——对已配置根目录与 harness home 的发现、受防护的按 agent 挂载，以及只复制的创作方式——`persona` 则提供可组装的行，让 preset 不止能改变 agent 的工具、也能改变它的身份。两者合起来让一个进程可以同时运行多个组装方式不同的 agent。

-Per-preset agent composition. A **preset** is a directory holding one `agent.cordis.yml`; the roster mounts it ONCE per process under a standing scope, and each session that names it joins by having its agent scope key parented to the mount's (`dsh-scope`'s parent chain). The mount's tools, prompt sections, and projection units exist exactly once and cover every joined agent — its plugins key their state by Session/Agent, so sessions stay apart inside one shared instance — and a host reader with no agent at all (a cold transcript read) resolves the same standing registrations by preset id.
+## Summary
 
-The mechanism is two seams. Entry contexts chain to the context a subtree was plugged into, and both [`dsh-tools`](../../core/tools/README.md) and [`dsh-system-prompt`](../../core/system-prompt/README.md) file registrations into the calling context's scope layer — so the standing mount's contributions land in the PRESET's layer. What carries them to each session is `dsh-scope`'s parent chain: an agent's views resolve `agent → preset → global` (nearest shadowing farthest), and the mount's listeners are admitted for every agent parented under it while a sibling preset's stay deaf.
+`dsh-agent-presets` composes each agent session from one preset: a directory holding a single `agent.cordis.yml` that names the plugins the session runs with. A session that names a preset gets that preset's tools, prompt sections, and skills, while every other session keeps its own, so one process can run several differently composed agents at once. The package maintains the preset roster: it lists every preset the configured roots supply — shipped ones and your own under `<dshHome>/.agent-presets` — shows a reason when a preset cannot start a session, and lets you create new presets by copying existing ones. The default preset is a setting you can override per deployment or per user, and a session can switch to a different preset only while it has produced nothing. A preset is as privileged as the plugins it names, so a preset you author carries the same trust as shell access.
 
-## Service: `AgentPresets` (ctx key: `agentPresets`)
+## Table of Contents
 
-Discovery is unmemoized: `list()` and `resolve()` re-read the roots on every call, so a preset authored while the process runs is visible immediately and a deleted one disappears from the next read. Discovery also owns preset **health**: a directory whose composition is missing or unloadable (unparsable YAML — checked with the loader's own dialect, `!!js` included — or not a list of named plugin rows) is listed with a `broken` reason rather than skipped, because a skipped directory would still occupy its id on disk while every surface shows nothing to delete. A directory whose name is not a usable preset id (`[a-z0-9][a-z0-9-]*`) is skipped outright: no copy could ever claim it.

-- `ctx.agentPresets.defaultId: string` The preset id mounted when a caller names none.
-- `ctx.agentPresets.list(): Promise<AgentPreset[]>` Every preset the configured roots currently supply, earlier root winning a duplicate id; broken presets included, each carrying its reason.
-- `ctx.agentPresets.resolve(id?): Promise<AgentPreset>` One preset by id, defaulting to `defaultId`. Throws naming the available ids when no root supplies it. A broken preset resolves — deleting, reading, and reporting one all need the row.
-- `ctx.agentPresets.mount(agentCtx, id?): Promise<AgentPreset>` Compose one agent from a preset — ensure its standing mount (single-flight) and parent the agent's scope key to it — returning the preset for the caller to record. Refuses a broken preset up front with its discovery-reported reason, so every unloadable shape fails the same way before the loader is involved.
-- `ctx.agentPresets.composeFrom(agentCtx, parentCtx): string | undefined` Join one agent to the standing composition another already runs on, returning the preset id joined — `undefined` when the parent joined none, which is the rosterless deployment and not an error. A bind rather than a mount, so it is synchronous and has no composition failure mode; it still rejects a caller error (an unscoped context, or an agent that already joined).
-- `ctx.agentPresets.composedPreset(agentCtx): string | undefined` The preset one LIVE agent runs on, read from its scope chain rather than from its session — the only answer available for an agent whose durable header is still being built.
-- `ctx.agentPresets.recompose(agentCtx, id): Promise<AgentPreset>` Re-link one agent to a different preset's standing composition. Valid only while the agent has produced nothing — **the caller owns that check**; the new mount is ensured before the link moves, so a failure leaves the agent as it was. A committed re-link emits `tools/change`, because the Agent's resolved tool set changed without a registry entry changing. Refuses a broken preset like `mount()`.
-- `ctx.agentPresets.standingKeyFor(id?): Promise<ScopeKey>` The standing scope key a host reader with no agent (a cold transcript read) resolves preset registrations in; ensures the mount without starting an agent, session, or turn. Refuses a broken preset like `mount()`.
-- `ctx.agentPresets.roots: readonly PresetRoot[]` The roots this roster scans — every configured root in order, then the derived harness-home root. Not `config.roots`: read this to answer whether a roster is composed at all, so one derivation decides it.
-- `ctx.agentPresets.authorable: boolean` Whether any of those roots has `user` trust, and therefore whether a preset can be created at all.
-- `ctx.agentPresets.read(id): Promise<string>` One preset's composition text, exactly as stored.
-- `ctx.agentPresets.copy(from, id, name?): Promise<void>` Create a locally authored preset by copying an existing one's whole directory — the only authoring write. No composition text crosses this seam, so a copy is exactly as loadable as its source; the copied metadata keeps the source's description but never its name or roster order, and `name` (or the id fallback) is what distinguishes the rows.
-- `ctx.agentPresets.remove(id): Promise<void>` Delete a locally authored preset; joined sessions keep their standing mount. Clears the user default when it named the preset just deleted: storing a default that does not exist yet is deliberate, but one this call removed will never be supplied again and would fail every session created without an explicit pick.
+-----
 
-`AgentPreset` carries `id` (the directory name), `trust` (`system` or `user`, from the root it was found under), `path` (the absolute composition file), and — only when the preset cannot compose a session — `broken` (one human-readable reason, shown verbatim on roster surfaces).
+<a id="use-this-package"></a>
+## Use this package
 
-### Where to call `mount()`
+Mount this package in a composition that should give each agent session its own tools, prompt sections, and skills from a preset file. Every session names a preset — explicitly or through the configured default — and is composed from it; without the package, sessions fall back to whatever the host composition mounts.
 
-The agent factory's `setup(agentCtx)` hook is the one supported call site. Only there is the join installed while the agent is still unpublished, so a rejected composition rolls the whole creation back rather than leaving a half-composed session. The standing subtree is owned by the roster service's own fiber — deliberately its UNTRACED context, because a subtree minted from a traced `this.ctx` resolves every service through the caller's shadow fiber instead of each entry's own inject store — so it survives every agent and unwinds only with the whole tree. Each generation records its composition file's stamp (mtime and size): a session that finds the stamp stale starts the next generation, while every session already joined keeps the one it runs on — the composition a running session joined outlives its file changing or disappearing underneath it, and files are the only composition editor, so the stamp is what carries an edit to later sessions.
+### What a preset gives a session
 
-### Composing a child agent
+A session composed from a preset runs the plugins that preset's `agent.cordis.yml` names: its tools, prompt sections, and skills. Sessions joined to the same preset share one installed composition, and each session's state stays separate. A child agent (subagent) joins its parent's composition, so it sees the same tools and prompt sections as the agent that spawned it.
 
-A subagent's child joins its parent's standing composition through `composeFrom()`, never through `mount()`. Every model-facing row lives on the agent plane, so the tool registry's global layer is empty and a child that joins nothing reaches the model with no tools at all and none of its parent's prompt sections.
+The presets you can choose from come from two places: the presets shipped inside this package under `presets/`, and your own presets under `<dshHome>/.agent-presets`. The picker shows each preset's display name and description; a preset whose composition cannot load is listed with the reason rather than hidden, so you can see what to fix or delete.
 
-Re-mounting the parent's preset by id would differ from the bind in two ways that both matter. A composition file edited since the parent started would hand the child a DIFFERENT generation than the one its parent's history was produced under, and a preset deleted since would fail the child outright while its parent keeps running. The bind is also synchronous, which is what lets the in-process subagent drivers use it at all — they compose their children inside a synchronous creation window.
+### Minimal configuration
 
-The child records the joined id on its own durable header ([`dsh-subagent`](../../subagent/subagent/README.md)), so a cold read of the child's history rebuilds the composition it actually ran under rather than the deployment default.
-
-### Which preset a session runs
-
-The creation header names the preset a session STARTED with; the `agentPreset` Session projection names the one it RUNS. They differ whenever a blank session switched, so every reconstruction path — the summary a picker reads, a resume, a fork — consumes that projection rather than reading the header or folding the log independently.
-
-The header stays frozen because it is a creation fact. A switch is an `agent-preset/selected` session event appended after the swap commits, which is what the model-visible ⟺ logged rule requires: the preset decides the tool schemas and prompt sections the model sees, so it has to be reconstructable from the log. The service re-emits that committed fact as the non-scoped cordis event `agent-preset/selected(sessionId, agentPreset)` declared by the client-safe `./types` export, allowing remote consumers to invalidate session-derived state without importing Host runtime types. Reading the header alone would rebuild a switched session under the composition it was created with, replaying history the new tool set cannot act on — the exact hazard the blank-only lock exists to prevent.
-
-### Switching a blank agent
-
-`recompose()` unmounts the installed subtree and mounts the new one, because two compositions cannot coexist — both would register the same tool names into one layer. A failed mount restores the previous composition rather than leaving the agent with nothing, and an unknown id is rejected before anything is torn down.
-
-The restriction to a produced-nothing agent is a product rule, not a mechanical one: swapping tools mid-conversation would leave logged tool calls the new composition cannot make. The gateway enforces it at the wire ([`dsh-apiproxy`](../../host/apiproxy/README.md) answers `agent-preset-locked`), which is where session history is in hand.
-
-## Authoring
-
-Authoring is copy-only. A new preset is a whole-directory copy of an existing one — composition, metadata, skill directories, assets — landed under the first `user` root; the inputs are two ids the service resolves against its own roots plus an optional display name, so no caller ever supplies composition text and a copy grants nothing the roster did not already carry. Everything after creation happens in the preset's own files. `copy()` refuses three things before anything lands:
-
-- **An id that is not `[a-z0-9][a-z0-9-]*`.** The id becomes a directory name, so containment is a property of the id itself rather than of a path check after the fact — `../escape`, `a/b`, and an absolute path are all rejected as ids.
-- **An id that is already taken.** A copy never overwrites: any root supplying the id refuses it (a user directory named like a shipped preset would be shadowed by it), and a directory occupying the name on disk refuses it too. Discovery lists such a directory as a broken preset, so the refusal's way out — delete it — is on the same page that reported it.
-- **An unknown source.** The source may be any trust — copying a shipped preset is the primary case — but it must exist; a failed copy rolls its half-made directory back rather than leaving one discovery cannot see.
-
-The copied tree is re-tightened to owner-only (`0o600` files keeping their owner-execute bit, `0o700` directories), symlinks are dereferenced so the copy is self-contained, and the root is created on first copy — a deployment configuring a user root that does not exist yet is the normal first-run state. The copied `preset.yml` is rewritten: the source's description is kept for the author to edit in place, but its name and roster `order` are dropped — a copy presenting itself identically to its source, or sorted into the shipped set's declared order, would make the roster stop distinguishing them. `remove()` refuses a preset that ships with the deployment; the shipped set is the known-good compositions copies start from.
-
-### How a preset's rows resolve
-
-A row's **package name** resolves from the host composition, not from the preset directory. The Loader normally resolves an entry against its own tree's `baseUrl`, which for a preset is wherever the composition file sits; a locally authored preset lives under the user's home, where Node's upward `node_modules` walk never reaches the harness, so every `@deepseek-ai/dsh-*` row would fail to import. The mount records the host base before plugging the subtree and sends bare specifiers there.
-
-A **relative** path still resolves from the preset's own directory, so a preset's own plugin files and skill directories travel with it.
-
-An **absolute** filesystem path keeps its own location. The mount converts it to a `file:` URL before ESM import so POSIX paths and Windows drive-letter or UNC paths use a specifier Node accepts.
-
-### Display metadata
-
-A preset may publish display text in an optional `preset.yml` beside its composition:
+The plugin needs a `default` preset id and scans `roots` for presets:
 
 ```yaml
-name: 极简模式
-description: 仅提供持久 bash 与 str_replace_editor 的双工具编码 Agent。
+- name: '@deepseek-ai/dsh-agent-presets'
+  config:
+    default: standard
+    roots:
+      - path: ~/company-presets
+        trust: system
 ```
 
-It carries display text ONLY. `id` is the directory name and `trust` comes from the root the preset was discovered under, so neither is writable here — otherwise a locally authored preset could name itself into the shipped set. It is a separate file because the composition is a top-level list of plugin rows: YAML cannot carry sibling keys beside it, and a fake metadata row would hand the Loader something to load.
-
-Every read failure degrades to no metadata — absent, malformed, wrongly typed, or blank all mean the same thing, and a picker falls back to the id. Presentation is not capability: a preset with a broken name still mounts.
-
-## Config
-
 | Field | Default | Meaning |
 |---|---|---|
-| `default` | required | Preset id mounted when a caller names none |
+| `default` | required | Preset id composed when a session names none |
 | `roots` | `[]` | Scanned directories in precedence order; each supplies `path` (a leading `~` expands) and `trust` (defaults to `user`) |
-| `includeShippedRoot` | `true` | Prepend the package's bundled shipped presets as a `system` root, before every configured root |
+| `includeShippedRoot` | `true` | Prepend the package's bundled presets as a `system` root before every configured root |
 | `includeUserRoot` | `true` | Append `<dshHome>/.agent-presets` as a `user` root, after every configured root |
 
-An absent root supplies no presets rather than failing: the user root does not exist until the first locally authored preset, and naming a default no root supplies already fails loud at resolution.
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-agent-presets) is the exhaustive source for every accepted field and its JSDoc.
 
-### The shipped and writable roots are this package's
+The shipped root is prepended before every configured root, so the built-in set remains available and wins duplicate ids even when a patch replaces the roster configuration. `includeShippedRoot: false` drops that built-in set for deployments that supply all presets themselves. `includeUserRoot: false` drops the derived writable root; tests that pin an exact roster disable both derived roots.
 
-The shipped presets travel inside this package, beside `lib/`, the way each preset's own skills travel inside its directory. Their root is PREPENDED before every configured root, so the built-in set always mounts and wins a duplicate id — no patch layer replacing the roster row's `config` can accidentally drop it, and the schema default keeps the set through a whole-`config` replacement. The compositions require the host's agent-plane services, not any one surface: a host lacking a service a preset row injects leaves that row waiting, exactly as under any other root.
+### Choosing the default preset
 
-`<dshHome>/.agent-presets` is where a person's own presets live, the way `<dshHome>/skills` is where their own skills live ([`dsh-skill-filesystem`](../../skill/skill-filesystem/README.md)), so the roster derives it rather than waiting for a deployment to remember it — a launcher that configures nothing still finds and authors presets. It is appended AFTER every configured root, which keeps an earlier root winning a duplicate id: a shipped `standard` still shadows a home directory that claimed the name, and `copy()` refuses that id rather than landing a preset nothing would resolve.
-
-The roots are resolved once, when the service is constructed. A root set that changed between a `list()` and the `copy()` acting on its answer would author into a directory the caller never saw.
-
-`includeShippedRoot: false` drops the built-in set — for a deployment supplying purely its own presets, or an embedder using the roster as bare machinery. `includeUserRoot: false` drops the derived writable root — for a deployment that confines presets to its own directories. A test pinning an exact roster sets both off; otherwise the package's shipped presets and the machine's real `<dshHome>` decide what the roster contains.
-
-The SHIPPED root stays an assembly fact: it sits beside the installed app's own config, a path only that app can resolve.
-
-### The default preset is a user setting
-
-When a settings provider is composed, this plugin registers the `agent-presets` namespace with `config.default` as its composition base, so the user document layers over the deployment's engineering default:
+The `default` config sets the deployment default. When a settings provider is composed, this plugin registers the `agent-presets` namespace with `config.default` as its base, so a user document layers a per-user default over the deployment's:
 
 ```yaml
 agent-presets:
   default: minimal
 ```
 
-The value is read per resolution rather than snapshotted, so a hot-reloaded document takes effect on the next session created and every running session stays on the preset it was composed from. Clearing the user field re-inherits the composition default. A default naming a preset no root supplies is stored without complaint and fails at the next `resolve()` — the roster is a live directory, so a name absent now may exist by the time a session asks for it.
+The value is read when a session is created, so a changed default affects only sessions created afterwards; running sessions stay on the preset they were composed from. Clearing the user field re-inherits the composition default.
 
-## What a mount rejects
+### Authoring presets
 
-A directly-plugged subtree is absent from `ctx.loader.entries()`, so no boot audit covers it. `mount()` therefore proves the result usable itself, and rejects three things.
+Authoring is copy-only: creating a preset copies an existing preset's whole directory — composition, display metadata, skill directories, assets — into the first `user` root. The copy keeps the source's description but gets its own id and an optional display name, so no caller supplies composition text and a copy grants nothing the roster did not already carry. After creation, everything happens in the preset's own files.
 
-**An unscoped target.** Mounting into a context that carries no agent scope would register the preset's tools globally, for every agent in the process.
+A copy is refused when the id is not `[a-z0-9][a-z0-9-]*` (the id becomes a directory name), when the id is already taken (a copy never overwrites), or when the source is unknown. Deleting removes only locally authored presets; presets that ship with the deployment are not removable. A session already running on a deleted preset keeps running on it.
 
-**A row that never became usable.** The loader already rejects a row whose module failed to import or whose plugin threw; what remains is a row still waiting for a service the composition never supplies, which the audit names.
+### Switching a session's preset
 
-**A row that published a service into the root realm.** Such a service is process-global, so the second preset publishing the same name collides with the first, and a host reader would resolve one preset's instance for every session. A preset that genuinely owns a service puts it behind an `isolate` realm — entry-local realms keep two presets' same-named services apart exactly as they once kept two sessions' apart — or the service belongs in the host composition instead.
+A session can switch to a different preset only while it has produced nothing — no messages or tool calls. After that, the composition is fixed for the session's life, because swapping tools mid-conversation would leave logged tool calls the new composition cannot make. A committed switch emits `tools/change` because the resolved tool set changed without a registry edit. The switch is also recorded in the session log, so a resumed or forked session rebuilds under the composition it ran.
 
-The package invariant re-checks that last rule on every service notification, because a row that publishes from a timer or an asynchronous continuation would escape the one-shot audit.
+### Failures and recovery
 
-## A preset file is an input, never a persistence target
+A preset whose composition is missing, unparsable, or not a list of named plugin rows is listed as broken with a one-line reason; composing such a preset is refused up front, so a session never starts half-composed. A composition that parses but names a missing package, or waits for a service the composition never supplies, fails at session creation, which rolls the creation back. Fix the preset's file or delete it, then retry.
 
-The Loader writes a tree back to its source file whenever it decides the config changed, and a row disposing its own fiber is enough to decide that: the entry is marked `disabled` and the tree is written. Inherited, that would burn one session's runtime state into a file every session shares — comments stripped by the YAML round trip, and a `writeFile` rejection inside a `setTimeout` for a read-only shipped preset.
+-----
 
-The mounted subtree therefore overrides `write()` as a no-op. Nothing in this package writes a composition; authoring one is a separate, explicit operation.

+<summary>Implementation internals — click to expand</summary>
 
-Presets are compositions, so a preset is exactly as privileged as the plugins it names. A `user` preset — authored by a person or by an agent — carries the same trust as shell access; the `trust` field exists so consumers can present that difference, not to enforce it.
+This section explains the design behind the roster and the standing mount; observable behavior is fully covered in [Use this package](#use-this-package).
 
+### Design philosophy
+
+- **One standing composition per preset.** A preset is mounted once per process under a standing scope; agents join by parenting their scope key to the mount, so the mount's registrations and listeners cover every joined agent and no sibling preset's.
+- **Generations keyed on the composition file.** The mount records the composition file's stamp (mtime and size); a session that finds the stamp stale starts the next generation, while sessions already joined keep the generation they run on — a running session outlives its file changing or disappearing.
+- **The preset file is an input, never a persistence target.** The mounted subtree overrides `write()` as a no-op, so a loader-initiated write-back never rewrites a shared preset file.
+- **Discovery owns health.** A directory whose composition is missing or unloadable is a broken roster row with a reason, not a skip — a skipped directory would still occupy its id while no surface shows anything to delete.

+
+### The standing mount
+
+`ensureStanding` keeps one pending promise per preset id, single-flight, so two agents racing the first use of a preset share one composition. A settled failure is removed so a later session retries a preset whose file has been fixed. The mount runs in the roster service's own untraced context — a subtree minted from a traced context would resolve services through the caller's shadow fiber — so it survives every agent and unwinds only with whole-tree teardown. `serviceForAgent` reads an agent's instance of a service its preset mounted behind an `isolate` realm, which is otherwise invisible outside the group.
+
+### The mount audit
+
+A directly-plugged subtree is absent from `ctx.loader.entries()`, so no boot audit covers it; `mountPreset` proves the result usable itself and rejects three shapes: an unscoped target (the preset's tools would register globally), a row still waiting for a service the composition never supplies, and a row that published a service into the root realm (process-global, so the second preset publishing the same name collides). The invariant companion re-checks the last rule on every service notification, because a row publishing from a timer or an asynchronous continuation would escape the one-shot audit.
+
+### Authoring mechanics
+
+A copy dereferences symlinks so it is self-contained, re-tightens the tree to owner-only (`0o600` files keeping their owner-execute bit, `0o700` directories), and creates the root on first copy. The copied `preset.yml` is rewritten: the source's description is kept for the author to edit, its name and roster `order` dropped, so the roster keeps distinguishing the copy from its source. Removal refuses presets that ship with the deployment and clears a user default that named the preset just deleted.
+
+### The session record
+
+The creation header names the preset a session started with; the `agentPreset` Session projection names the preset it runs. A switch appends an `agent-preset/selected` event after the swap commits because the preset decides the tool schemas and prompt sections the model sees. The service re-emits that committed fact as the unscoped cordis event `agent-preset/selected(sessionId, agentPreset)`. Reconstruction consumes the projection, which starts from the creation header and applies the newest selection; it never folds the log independently.

 ## Known Limitations and Deferred Work
 
-- **A preset outside the writable root is discoverable but not deletable** — `remove()` refuses anything that does not live under the FIRST `user` root, so a deployment that configures its own writable root while leaving `includeUserRoot` on lists the harness-home presets, mounts them, and then answers "it does not live under the writable preset root" for every delete. The roster carries one writable root by design; a deployment that wants only its own sets `includeUserRoot: false`.
-- **A preset cannot be changed once a session has produced anything** — `recompose` re-links a BLANK session's parent scope to another standing mount, and only a blank one: switching a composition that already ran would strand tools the model has called. Changing the default affects only sessions created afterwards.

-- **A superseded generation is never reclaimed** — sessions already joined keep the generation they run on, and the roster holds no join count that could tell when the last one left, so the whole subtree stays mounted until the process ends. The cost is per generation rather than per session, but it is not free: `dsh-skill-filesystem` watches its roots by default, so each edit-then-create cycle adds a live watcher set. Bounded by how often compositions are edited — which the settings-page authoring flow makes a per-save event rather than a per-deploy one. Reclaiming one needs a joined-agent count on the standing mount; see the `TODO` at `ensureStanding`.
+- **A superseded generation is never reclaimed** — sessions already joined keep the generation they run on, and the roster holds no join count that could tell when the last one left, so the whole subtree stays mounted until the process ends. The cost is per generation rather than per session, but it is not free: `dsh-skill-filesystem` watches its roots by default, so each edit-then-create cycle adds a live watcher set.
 - **A copy is never mounted to validate** — it is byte-identical to its source, so a source broken on disk yields a copy exactly as broken as the source; discovery's health check marks both rows on the next roster read rather than deferring the failure to a session start.
 - **Health is a shape check, not a mount** — discovery proves the composition parses in the loader dialect and holds named rows, not that every row's module resolves or activates; a row naming an absent package still fails at the first session, which rolls the creation back.
-- **A copy is a snapshot that drifts** — upgrading the deployment does not update copies of shipped presets, and there is no patch semantics at this layer to express "standard plus one change" (that is the bundle layer's `cordis.patch.yml`); the shipped set itself accepts the same cost — `cordis` and `code` are full copies of `standard` — so the whole assembly stays readable in one file.
+- **A copy is a snapshot that drifts** — upgrading the deployment does not update copies of shipped presets, and there is no patch semantics at this layer to express "standard plus one change"; the shipped set itself accepts the same cost — `cordis` and `code` each duplicate `standard`'s full assembly and then edit it — so the whole assembly stays readable in one file.
 - **Root scans are not watched** — every read hits the filesystem instead, which keeps the roster fresh but puts one `readdir` per root on each `list()`.

+#### Future: reclaiming superseded generations
+
+Reclaiming a superseded standing mount needs a joined-agent count on `StandingMount`, incremented in `mount`/`composeFrom`/`recompose` and decremented when the agent's scope key dies — the `TODO` at `ensureStanding`. The subtree is not inert: `dsh-skill-filesystem` watches its roots, so an unreclaimed generation keeps a live watcher set alive until the process ends.

 [English](README.md) | 中文
 
-按 preset 组装 agent（智能体）。**preset** 是一个目录，其中放置一份 `agent.cordis.yml`；roster 在整个进程内只把它挂载一次（常驻 scope），命名它的每个会话通过把自己 agent 的 scope key 认父到该挂载（`dsh-scope` 的父链）来加入。挂载的工具、提示词段落与投影单元只存在一份，覆盖所有已加入的 agent——其插件本就按 Session/Agent 分键存状态，会话在共享实例内互不串扰——而完全没有 agent 的宿主读取方（冷读记录）也能按 preset id 解析到同一份常驻注册。
+## 概述
 
-其机制是两条 seam。entry 上下文沿原型链连到子树被挂载时所在的上下文，而 [`dsh-tools`](../../core/tools/README.zh.md) 与 [`dsh-system-prompt`](../../core/system-prompt/README.zh.md) 本就按调用方上下文的 scope 分层归档注册——因此常驻挂载的贡献落在 **preset 的分层**里。把它们送达每个会话的是 `dsh-scope` 的父链：agent 的视图按 `agent → preset → global` 解析（近者遮蔽远者），挂载的监听器对认父到它的每个 agent 放行，而兄弟 preset 的监听器保持失聪。
+`dsh-agent-presets` 让每个 agent（智能体）会话都从同一个 preset 组装：preset 是一个目录，内含一份 `agent.cordis.yml`，列出该会话运行的插件。命名某个 preset 的会话会获得该 preset 的工具、提示词段落与 skill（技能），而其他会话各自保持自己的，因此一个进程可以同时运行多个组装方式不同的 agent。本包维护 preset 名单：它列出已配置根目录提供的每个 preset——随附的与你自己放在 `<dshHome>/.agent-presets` 下的——在 preset 无法启动会话时给出原因，并允许你通过复制既有 preset 来创建新 preset。默认 preset 是一项可按部署或按用户覆盖的设置，会话只有在尚未产出任何内容时才能切换 preset。preset 的权限恰好等于它所引用插件的权限，因此你创作的 preset 与 shell 访问权限同级。
 
-## 服务：`AgentPresets`（ctx 键：`agentPresets`）
+## 目录
 
-发现过程不做缓存：`list()` 与 `resolve()` 每次调用都重新读取各个根目录，因此进程运行期间新写的 preset 立即可见，被删除的 preset 也会在下一次读取时消失。发现过程同时负责 preset 的**健康**：组装文件缺失或不可加载（YAML 无法解析——用加载器自己的方言检查，含 `!!js`——或不是由具名插件行组成的列表）的目录会作为携带 `broken` 原因的行列出而不是被跳过，因为被跳过的目录仍在磁盘上占着它的 id，而各个界面却没有任何可删的东西。目录名不是可用 preset id（`[a-z0-9][a-z0-9-]*`）的目录才被直接跳过：复制永远不可能占用那种名字。

-- `ctx.agentPresets.defaultId: string` 调用方未指定时挂载的 preset id。
-- `ctx.agentPresets.list(): Promise<AgentPreset[]>` 当前各根目录提供的全部 preset；id 重复时靠前的根目录胜出；损坏的 preset 也在其中，各自携带原因。
-- `ctx.agentPresets.resolve(id?): Promise<AgentPreset>` 按 id 取一个 preset，缺省取 `defaultId`。没有任何根目录提供该 id 时抛错，并列出可用 id。损坏的 preset 照样解析——删除、读取与上报都需要这一行。
-- `ctx.agentPresets.mount(agentCtx, id?): Promise<AgentPreset>` 用一个 preset 组装一个 agent——确保其常驻挂载（并发去重）并把 agent 的 scope key 认父到它——返回该 preset 供调用方记录。对损坏的 preset 直接以发现时记下的原因拒绝，所以每种不可加载的形态都在加载器介入之前以同一方式失败。
-- `ctx.agentPresets.composeFrom(agentCtx, parentCtx): string | undefined` 让一个 agent 加入另一个 agent 已在运行的常驻组装，返回所加入的 preset id——父方未加入任何 preset 时返回 `undefined`，那是无 roster 的部署，不是错误。这是认父而非挂载，因此同步、且自身没有组装失败模式；调用方用错（上下文无 scope、agent 已加入过）仍会拒绝。
-- `ctx.agentPresets.composedPreset(agentCtx): string | undefined` 某个**活着的** agent 正在运行的 preset，从其 scope 链读取而不是从其会话读取——对于持久化 header 尚在构建中的 agent，这是唯一能拿到的答案。
-- `ctx.agentPresets.recompose(agentCtx, id): Promise<AgentPreset>` 把一个 agent 重链到另一个 preset 的常驻组装。仅在该 agent 尚无任何产出时合法——**由调用方负责该检查**；新挂载在链移动之前确保完成，失败时 agent 原封不动。重链提交后会发出 `tools/change`，因为 Agent 解析到的工具集已经变化、但注册表条目本身没有增删。与 `mount()` 一样拒绝损坏的 preset。
-- `ctx.agentPresets.standingKeyFor(id?): Promise<ScopeKey>` 没有 agent 的宿主读取方（冷读记录）解析 preset 注册所用的常驻 scope key；确保挂载而不启动任何 agent、会话或轮次。与 `mount()` 一样拒绝损坏的 preset。
-- `ctx.agentPresets.roots: readonly PresetRoot[]` 本 roster 实际扫描的根目录——全部已配置根目录按序在前，随后是推导出的 harness home 根目录。它不是 `config.roots`：判断「是否已组装 roster」应读它，从而由同一处推导决定。
-- `ctx.agentPresets.authorable: boolean` 上述根目录中是否有任一具备 `user` 信任级别，因而 preset 是否可创建。
-- `ctx.agentPresets.read(id): Promise<string>` 某个 preset 的组装文本，与存储内容逐字一致。
-- `ctx.agentPresets.copy(from, id, name?): Promise<void>` 通过整目录复制一个既有 preset 来创建本地创作的 preset——唯一的创作写入。组装文本不经过这道接缝，因此副本与其来源同等可加载；复制出的元数据保留来源的描述、但绝不保留其名称与 roster 排序，`name`（或回退到 id）才是区分两行的依据。
-- `ctx.agentPresets.remove(id): Promise<void>` 删除一个本地创作的 preset；已加入的会话保留其常驻挂载。若用户默认值恰好指向刚删除的 preset 则一并清除：存一个尚不存在的默认值是刻意的，但本次删除的这个再也不会有人提供，留着会让所有未显式指定的新会话无法启动。
+-----
 
-`AgentPreset` 携带 `id`（目录名）、`trust`（`system` 或 `user`，取自它所在的根目录）、`path`（组装文件的绝对路径），以及——仅当该 preset 无法组装会话时——`broken`（一条人类可读的原因，名单界面原样展示）。
+<a id="use-this-package"></a>
+## 使用本包
 
-### 应在何处调用 `mount()`
+在需要让每个 agent 会话从 preset 文件获得自己的工具、提示词段落与 skill 的组装中挂载本包。每个会话都会命名一个 preset——显式指定或通过配置的默认值——并据此组装；没有本包时，会话只能回退到宿主组装挂载的内容。
 
-agent 工厂的 `setup(agentCtx)` 钩子是唯一受支持的调用点。只有在那里，认父是在 agent 尚未发布时完成的，因此组装被拒绝会让整次创建回滚，而不会留下一个组装到一半的会话。常驻子树归 roster 服务自己的 fiber 所有——刻意用其未追踪的上下文，因为从被追踪的 `this.ctx` 派生的子树会经调用方的 shadow fiber 解析一切服务、无视各 entry 自己的 inject store——所以它比任何 agent 都活得久，只随整棵树卸载。每个代际记录其组装文件的 stamp（mtime 与大小）：发现 stamp 过期的会话会开启下一个代际，而所有已加入的会话保持各自正在运行的那个——正在运行的会话所加入的组装在其文件被修改或删除后继续存活；文件是唯一的组装编辑器，stamp 正是把编辑送达后续会话的机制。
+### preset 给会话带来什么
 
-### 组装子 agent
+从 preset 组装的会话会运行该 preset `agent.cordis.yml` 所列插件：它的工具、提示词段落与 skill。加入同一 preset 的会话共享一份已安装的组装，且各会话的状态彼此隔离。子 agent（subagent）会加入其父方的组装，因此它看到的工具与提示词段落和创建它的 agent 相同。
 
-subagent 的子 agent 通过 `composeFrom()` 加入其父方的常驻组装，绝不走 `mount()`。所有面向模型的行都在 agent 平面，工具注册表的全局层是空的，因此没有加入任何组装的子 agent 抵达模型时既没有任何工具，也没有父方的任何提示段。
+可选的 preset 来自两处：本包 `presets/` 下随包交付的 preset，以及你自己放在 `<dshHome>/.agent-presets` 下的 preset。选择器会展示每个 preset 的显示名与描述；组装无法加载的 preset 会连同原因一起列出而不是被隐藏，因此你能看到该修什么或删什么。
 
-按 id 重新挂载父方的 preset 与认父有两处差别，且两处都要紧。父方启动后被编辑过的组装文件会把与父方历史所产出时**不同**的一个代际交给子 agent；而此后被删除的 preset 会让子 agent 直接失败，尽管其父方仍在正常运行。认父还是同步的，这正是进程内 subagent 驱动能够使用它的前提——它们在同步的创建窗口里组装子 agent。
+### 最小配置
 
-子 agent 会把所加入的 id 记在自己的持久化 header 上（见 [`dsh-subagent`](../../subagent/subagent/README.zh.md)），因此冷读子 agent 的历史时重建的是它实际运行过的组装，而不是部署默认值。
-
-### 会话实际运行的是哪个 preset
-
-创建头部记录的是会话**以什么开始**，`agentPreset` Session projection 记录的才是它**实际运行的**。空白会话一旦切换过，两者就不同，因此所有重建路径——选择器读取的摘要、resume、fork——都消费该 projection，而非直接读头部或各自重新归约日志。
-
-头部保持冻结，因为它是创建期事实。切换以 `agent-preset/selected` 会话事件记录，在替换提交之后追加；这正是 model-visible ⟺ logged 规则的要求：preset 决定模型看到的工具 schema 与提示词段落，因此必须能从日志重建。服务会把这项已提交事实重新发为不带 scope 的 cordis 事件 `agent-preset/selected(sessionId, agentPreset)`，其声明位于 client-safe 的 `./types` 出口，使远端消费方无需导入 Host 运行时类型即可让会话派生状态失效。只读头部会让切换过的会话按创建时的组装重建，从而重放新工具集无法执行的历史——这正是「仅空白可切」那道锁要防的危险。
-
-### 切换空白 agent
-
-`recompose()` 先卸载已装入的子树、再装入新的，因为两份组装无法共存——它们会把相同的工具名注册进同一个层。挂载失败会恢复先前的组装，而不是让 agent 一无所有；未知 id 则在任何东西被拆除之前就被拒绝。
-
-"仅限尚未产出任何内容的 agent"是一条产品规则而非机制约束：在对话进行中调换工具，会留下新组装无法执行的、已被记录的工具调用。该规则由网关在传输层执行（[`dsh-apiproxy`](../../host/apiproxy/README.zh.md) 返回 `agent-preset-locked`），因为会话历史在那里才拿得到。
-
-## 创作
-
-创作即复制。新 preset 是某个既有 preset 的整目录副本——组装、元数据、skill 目录、附带资产——落在首个 `user` 根目录之下；输入只有两个由服务对照自身根目录解析的 id 加一个可选显示名，因此调用方从不提供组装文本，一次复制不会授予 roster 尚未携带的任何能力。创建之后的一切都发生在 preset 自己的文件里。`copy()` 在任何内容落盘之前拒绝三种情况：
-
-- **不符合 `[a-z0-9][a-z0-9-]*` 的 id。** id 会成为目录名，因此约束是 id 自身的性质，而非事后再做一次路径检查——`../escape`、`a/b` 与绝对路径都作为 id 被拒绝。
-- **已被占用的 id。** 复制从不覆写：任一根目录已提供该 id 即拒绝（与随附 preset 同名的用户目录只会被它遮蔽），磁盘上占着该名字的目录同样拒绝。发现过程会把这样的目录列为损坏的 preset，所以这条拒绝的出路——删掉它——就在报告它的同一页面上。
-- **未知的来源。** 来源可以是任何信任级别——复制随附 preset 正是主要用途——但必须存在；复制失败会回滚做到一半的目录，而不是留下一个 discovery 看不见的目录。
-
-复制出的目录树被收紧为仅属主可用（文件 `0o600` 并保留属主执行位，目录 `0o700`），符号链接被解引用以保证副本自包含，且根目录在首次复制时创建——部署配置了尚不存在的用户根目录，正是首次运行的正常状态。复制出的 `preset.yml` 会被重写：保留来源的描述供作者就地编辑，但丢弃其名称与 roster `order`——副本若与来源呈现得一模一样、或按随附集合声明的顺序排序，roster 就不再能区分它们。`remove()` 拒绝随部署提供的 preset；随附集合正是副本的已知良好起点。
-
-### preset 的各行如何解析
-
-行的**包名**从宿主组装解析，而非从 preset 目录解析。Loader 通常按 entry 所属树的 `baseUrl` 解析，而对 preset 而言那就是组装文件所在之处；本地创作的 preset 位于用户主目录之下，Node 向上查找 `node_modules` 永远够不到 harness，因此每一个 `@deepseek-ai/dsh-*` 行都会导入失败。挂载在插入子树之前先记录宿主的基址，并把裸标识符送往那里。
-
-**相对**路径仍从 preset 自身的目录解析，因此 preset 自带的插件文件与 skill 目录会随它一同迁移。
-
-**绝对**文件系统路径则保留其自身位置。挂载会先将它转换为 `file:` URL 再交给 ESM 导入，从而使 POSIX 路径和 Windows 盘符或 UNC 路径都采用 Node 能够接受的说明符。
-
-### 展示用元信息
-
-preset 可以在组装文件旁的可选 `preset.yml` 里发布展示文本：
+插件需要一个 `default` preset id，并在 `roots` 中扫描 preset：
 
 ```yaml
-name: 极简模式
-description: 仅提供持久 bash 与 str_replace_editor 的双工具编码 Agent。
+- name: '@deepseek-ai/dsh-agent-presets'
+  config:
+    default: standard
+    roots:
+      - path: ~/company-presets
+        trust: system
 ```
 
-它**只**承载展示文本。`id` 是目录名，`trust` 取自 preset 被发现时所在的根目录，两者都不可写在这里——否则本地创作的 preset 就能把自己命名进随附集合。之所以是独立文件：组装是插件行的顶层列表，YAML 无法在其旁携带同级键，而伪造一个元信息行等于递给 Loader 一个要加载的东西。
-
-任何读取失败都退化为「没有元信息」——缺失、格式错误、类型不对、内容为空，含义相同，选择器回退到 id。展示不是能力：名字坏掉的 preset 依然能挂载。
-
-## 配置
-
 | 字段 | 默认值 | 含义 |
 |---|---|---|
-| `default` | 必填 | 调用方未指定时挂载的 preset id |
+| `default` | 必填 | 会话未指定时组装的 preset id |
 | `roots` | `[]` | 按优先级排列的扫描目录；每项提供 `path`（开头的 `~` 会展开）与 `trust`（默认为 `user`） |
-| `includeShippedRoot` | `true` | 在全部已配置根目录之前，前置本包随附的内置 preset 作为 `system` 根目录 |
-| `includeUserRoot` | `true` | 在全部已配置根目录之后，追加 `<dshHome>/.agent-presets` 作为 `user` 根目录 |
+| `includeShippedRoot` | `true` | 在全部已配置根目录之前，前置本包随附的 preset 作为 `system` 根目录 |
+| `includeUserRoot` | `true` | 在全部已配置根目录之后追加 `<dshHome>/.agent-presets` 作为 `user` 根目录 |
 
-根目录不存在时视为不提供任何 preset，而非失败：用户根目录在写出第一个本地 preset 之前并不存在，而指定了没有任何根目录提供的默认值，在解析时本就会明确报错。
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-agent-presets)是每个受支持字段及其 JSDoc 的穷尽式真源。
 
-### 随附根目录与可写根目录都属于本包
+随附根目录前置在全部已配置根目录之前，因此即使补丁替换 roster 配置，内置集合仍然可用并赢得重复 id。`includeShippedRoot: false` 会为完全自行提供 preset 的部署移除内置集合。`includeUserRoot: false` 会移除推导出的可写根目录；钉住确切 roster 的测试会同时关闭两个推导根目录。
 
-随附的 preset 就在本包内部、`lib/` 旁随行分发，正如每个 preset 自己的 skill 随其目录一起走。其根目录前置在全部已配置根目录**之前**，因此内置集合始终挂载并赢得重复 id——任何整体替换 roster 行 `config` 的补丁层都不会意外弄丢它，schema 默认值让该集合在整份 `config` 被替换后依然保留。这些组合依赖的是宿主的 agent-plane 服务，而不是某个特定表面：宿主缺少某个 preset 行注入的服务时，该行保持等待，与任何其他根目录下的 preset 无异。
+### 选择默认 preset
 
-`<dshHome>/.agent-presets` 是个人自有 preset 的所在，正如 `<dshHome>/skills` 是其自有 skill 的所在（[`dsh-skill-filesystem`](../../skill/skill-filesystem/README.zh.md)），因此 roster 自行推导它，而不等某个部署记得配置——一个什么都没配的启动器同样能发现并创作 preset。它追加在全部已配置根目录**之后**，从而保持靠前的根目录赢得重复 id：随附的 `standard` 仍然遮蔽一个占用该名字的家目录目录，而 `copy()` 会拒绝该 id，不会落下一个无人解析得到的 preset。
-
-根目录在服务构造时解析一次。若根目录集合在一次 `list()` 与依据其答案执行的 `copy()` 之间发生变化，写入的将是调用方从未见过的目录。
-
-`includeShippedRoot: false` 去掉内置集合——适用于只提供自有 preset 的部署，或把 roster 当作纯机制使用的嵌入方。`includeUserRoot: false` 去掉推导出的可写根目录——适用于把 preset 限制在自有目录内的部署。钉住确切 roster 的测试两者都要关——否则将由本包的随附 preset 与这台机器真实的 `<dshHome>` 决定 roster 的内容。
-
-随附根目录仍然是装配事实：它位于已安装 app 自身配置的旁边，那个路径只有该 app 能解析。
-
-### 默认 preset 是一项用户设置
-
-当组装中存在 settings 提供方时，本插件会注册 `agent-presets` 命名空间，并以 `config.default` 作为其组装 base，因此用户文档会层叠覆盖部署方的工程默认值：
+`default` 配置设定部署级默认值。当组装中存在 settings 提供方时，本插件会注册 `agent-presets` 命名空间，并以 `config.default` 作为其 base，因此用户文档会在部署默认值之上层叠一份按用户设置的默认值：
 
 ```yaml
 agent-presets:
   default: minimal
 ```
 
-该值在每次解析时读取而非快照，因此热重载的文档对**此后创建**的会话生效，而每个运行中的会话仍停留在它当初据以组装的 preset 上。清空用户字段即重新继承组装默认值。若默认值指向没有任何根目录提供的 preset，写入时不会报错，而在下一次 `resolve()` 时失败——名单是一个活动目录，此刻不存在的名字，等到某个会话真正索取时可能已经存在。
+该值在会话创建时读取，因此更改默认值只影响此后创建的会话；运行中的会话仍停留在它们当初据以组装的 preset 上。清空用户字段即重新继承组装默认值。
 
-## 挂载会拒绝什么
+### 创作 preset
 
-直接挂载的子树不会出现在 `ctx.loader.entries()` 中，因此没有任何启动审计能覆盖它。`mount()` 因此自行校验结果可用，并拒绝三种情况。
+创作即复制：创建 preset 会复制某个既有 preset 的整个目录——组装、展示元数据、skill 目录与资产——放进第一个 `user` 根目录。副本保留来源的描述，但拥有自己的 id 与可选显示名，因此调用方从不提供组装文本，一次复制也不会授予名单尚未携带的任何能力。创建之后的一切都发生在 preset 自己的文件里。
 
-**目标上下文没有 scope。** 挂载到不带 agent scope 的上下文，会把该 preset 的工具注册成全局的，作用于进程内每一个 agent。
+以下情况会拒绝复制：id 不符合 `[a-z0-9][a-z0-9-]*`（id 会成为目录名）、id 已被占用（复制从不覆写）、或来源未知。删除只移除本地创作的 preset；随部署提供的 preset 不可删除。已在被删除 preset 上运行的会话会继续运行。
 
-**某一行始终未进入可用状态。** 模块导入失败或插件抛错的行，loader 已经会拒绝；剩下的情况是某一行仍在等待该组装从未提供的服务，审计会指名这种情况。
+### 切换会话的 preset
 
-**某一行把服务发布进了根 realm。** 这类服务是进程级全局的，因此第二个发布同名服务的 preset 会与第一个相撞，宿主读取方也会把某一个 preset 的实例当成所有会话的。确实需要自带服务的 preset，应把它放在 `isolate` realm 之后——entry 本地 realm 让两个 preset 的同名服务互不相干，正如它从前隔开两个会话——否则该服务应改放进宿主组装。
+会话只有在尚未产出任何内容——没有消息或工具调用——时才能切换到不同的 preset。此后组装在会话的生命周期内固定，因为在对话中途调换工具会留下新组装无法执行的已记录工具调用。已提交的切换会发出 `tools/change`，因为解析后的工具集在没有注册表编辑的情况下发生了变化。切换也会记入会话日志，因此恢复或 fork 的会话会按它运行的组装重建。
 
-最后一条规则由本包的运行时不变量在每次服务通知时复查，因为从定时器或异步续体中发布的行会绕过一次性审计。
+### 失败与恢复
 
-## preset 文件是输入，不是持久化目标
+组装缺失、无法解析或不是具名插件行列表的 preset 会被列为 broken，并附带一行原因；组装此类 preset 会被提前拒绝，因此会话绝不会以半组装状态启动。能解析但引用了缺失包、或等待组装从未提供的服务的组装，会在会话创建时失败并回滚创建。修复 preset 的文件或删除它，然后重试。
 
-只要 Loader 认为配置变了，它就会把树写回源文件——而一个行释放自己的 fiber 就足以让它这么认为：该 entry 被标记 `disabled`，随即触发写回。若继承该行为，一个会话的运行时状态就会被烧进所有会话共享的文件里：YAML 往返会抹掉注释，而对随附的只读 preset，`writeFile` 还会在 `setTimeout` 内抛出无人接管的 rejection。
+-----
 
-因此被挂载的子树把 `write()` 覆写为空操作。本包不写任何组装；创作组装是另一件独立且显式的操作。

-preset 就是组装，因此一个 preset 的权限恰好等于它所引用的插件。`user` preset——无论由人还是由 agent 写出——与 shell 访问权限同级；`trust` 字段的存在是为了让消费方呈现这一差异，而不是用来强制隔离。
+本节解释名单与常驻挂载背后的设计；可观察行为已在[使用本包](#use-this-package)中完整说明。
 
+### 设计理念
+
+- **每个 preset 一份常驻组装。** preset 在进程内只挂载一次，挂到常驻 scope 之下；agent 通过把自己的 scope key 认父到该挂载来加入，因此挂载的注册与监听器覆盖每个已加入的 agent，而不覆盖兄弟 preset 的。
+- **代际以组装文件为键。** 挂载记录组装文件的 stamp（mtime 与大小）；发现 stamp 过期的会话会开启下一个代际，而已加入的会话保持各自运行的那个代际——运行中的会话在文件被修改或删除后继续存活。
+- **preset 文件是输入，绝不是持久化目标。** 被挂载的子树把 `write()` 覆写为空操作，因此 loader 发起的写回绝不会重写共享的 preset 文件。
+- **发现过程拥有健康。** 组装缺失或不可加载的目录是携带原因的 broken 名单行，而不是被跳过——被跳过的目录仍占着它的 id，而任何界面都没有可删的东西。

+
+`ensureStanding` 为每个 preset id 保留一个进行中的 promise（single-flight），因此两个竞争首次使用同一 preset 的 agent 共享一份组装。已结算的失败会被移除，以便后续会话重试文件已被修复的 preset。挂载运行在 roster 服务自己的未追踪上下文中——从被追踪上下文派生的子树会经调用方的 shadow fiber 解析服务——因此它比任何 agent 都活得久，只随整棵树卸载。`serviceForAgent` 读取某 agent 对其 preset 挂在 `isolate` realm 之后（组外不可见）的某个服务实例。

 在一个 agent 的整个生命周期内保持前缀稳定：组装只装入一次，发生在 agent 发布之前、因而也在它的首个请求之前，且在 agent 运行期间不再重新读取。为新会话选择不同的 preset，只会为该会话建立不同的前缀，无法让任何已在运行的会话失去缓存复用。

-The agent persona as a composable row. It can either shadow the deployment persona or own the complete system prompt.
+## Summary
 
-[`dsh-system-prompt`](../../core/system-prompt/README.md) owns the deployment persona as its own config and registers that section unconditionally, so a process has exactly one. An [agent preset](../agent-presets/README.md) cannot mount the prompt registry itself — without a row of its own, a preset could change an agent's tools but never its identity. This package is that row.
+`dsh-persona` gives one agent its own persona: a preset mounts this composable row to register the `deployment:persona` system-prompt section, shadowing the deployment-wide persona for that session. It can also make that persona the session's complete system prompt, suppressing every other section, and can turn off dynamic runtime-context snapshots for the session. Mount it inside a preset composition — mounting it globally collides with the prompt registry's own persona registration and fails loud. Without this row, a preset could change an agent's tools but never its identity.
 
-## Scope-only
+## Table of Contents
 
-Mounting this row outside an agent scope collides with the registry's own `deployment:persona` registration and fails loud. That is not a limitation to work around: the deployment persona already has an owner, and the whole point of this row is to shadow it for one agent. Mount it inside a preset composition, where the preset mount supplies the agent scope.

+### Persona behavior
+
+The persona `text` is a template: complete `{{…}}` groups resolve strictly against registered prompt variables when the prompt renders, not when it assembles. Empty text still occupies the slot — it shadows the deployment persona away entirely, then disappears at render. With `complete: true`, assembly still resolves contexts, tools, variables, and cooperative listeners, but the prompt registry restores this exact persona as the sole section; no identity, tool guidance, or listener can append prompt text. With `includeRuntimeContext: false`, context providers are not evaluated for this scope and contexts added by assembly listeners are discarded.
+
+### When to use it
+
+Use this row when a preset must change an agent's identity and not only its tools. The deployment-wide persona itself is configured on the `dsh-system-prompt` row, not here; this row exists only to shadow or replace it for one agent.

+<details>

+
+### How the row registers
+
+`apply` registers one prompt section through `ctx.systemPrompt.section({ name: PERSONA_SECTION, order: PERSONA_ORDER, text, complete? })` inside the mounting context's scope, so the section lands at order 0 — immediately after the harness identity opener — and only for agents joined to the preset. `PERSONA_SECTION` and `PERSONA_ORDER` are imported from `dsh-system-prompt` rather than restated, so a preset persona always shadows the deployment's instead of landing beside it. `includeRuntimeContext: false` calls `ctx.systemPrompt.suppressRuntimeContext()`.
+
+### Why the row is scope-only
+
+`dsh-system-prompt` owns the global persona as its own config and registers `deployment:persona` unconditionally, so a process has exactly one. This row collides with that registration outside an agent scope, by design: the row exists because a preset cannot mount the prompt registry itself.

 ### The persona section
 
 #### What the model sees
 
-The `deployment:persona` section at order 0, immediately after the harness identity opener, carrying exactly this row's configured `text` with prompt variables resolved. For an agent whose preset mounts this row, it replaces whatever persona the deployment configured. In complete mode, the model sees only this rendered section as its system prompt. Runtime context remains enabled by default. When disabled, a fresh agent receives no runtime-context snapshot from sandbox policy, approval policy, delegation, or another system-prompt context provider.

-Configurable diagnostics that check package-owned runtime relationships without changing product behavior.
+## Summary
+
+The runtime-diagnostics group provides runtime self-checking for DeepSeek Harness compositions: one package, `invariants`, runs package-owned checks that verify each package's durable event and data relationships while the composition is live. A violation surfaces as an error attributed to the package that owns the relationship; a global switch and package-name filters control which checks run. Use this group's package when a composition should verify its own runtime contracts as part of normal operation.

-Configurable registry service for package-owned runtime invariant checks. The root plugin registers `ctx.invariants`; it contains no product checks or product-package imports. Every workspace package publishes a `./invariant` companion that registers its exact npm package name.
+## Summary
 
-## Service: `InvariantRegistry` (`ctx.invariants`)
+`dsh-invariants` runs package-owned runtime checks — invariants — inside a DeepSeek Harness composition: any package can ship a `./invariant` companion that verifies its own durable relationships (authoritative event streams and mutable snapshots) while the composition runs. Checks run automatically, and a failed check reports an `InvariantError` attributed to the package that owns the violated relationship. Choose it for compositions that want self-checking diagnostics with a global switch and package-name filters; the standard agent composition already mounts it with the four core companions, and loading the service alone installs no checks.

-interface Config {
-  enabled?: boolean
-  package_allowlist?: string[]
-  package_blocklist?: string[]

+## Use this package
+
+Mount the registry when a composition should verify its own runtime contracts, then decide which packages' checks run. The service exposes `ctx.invariants`; companions register checks under their package's exact npm name, and every failure carries the owning package name.
+
+### When to use it
+
+Use the registry for compositions that want live diagnostics. The standard agent composition in [`agent-spine-demo`](../../../packages/examples/agent-spine-demo/README.md) already mounts it with the four core stateful companions — `dsh-session`, `dsh-agent`, `dsh-scope`, and `dsh-agent-loop`. Custom compositions mount the registry and add companions for any other loaded package whose contracts they want checked. Loading the registry alone installs no checks: it ships no product checks of its own, so a composition that never mounts a companion observes no diagnostic behavior.
+
+### Enabling checks and selecting packages
+
+The registry is enabled by default and checks every registered package unless filters say otherwise. Use `enabled` as a global switch, `package_allowlist` to admit only named packages, and `package_blocklist` to exclude packages after allowlist matching — a blocklist match overrides an allowlist match. Patterns are case-sensitive JavaScript regular-expression sources (unanchored unless they supply `^` and `$`), and an invalid, blank, or duplicate entry fails service startup instead of being skipped.
+
+```yaml
+- name: '@deepseek-ai/dsh-invariants'
+  config:
+    enabled: true
+    package_allowlist:
+      - '^@deepseek-ai/dsh-'
 ```
 
-Defaults are `enabled: true`, `package_allowlist: []`, and `package_blocklist: []`. A package is selected only when the service is enabled, the allowlist is empty or at least one allowlist pattern matches its full npm name, and no blocklist pattern matches. Blocklist matches therefore override allowlist matches.
+| Field | Default | Meaning |
+|---|---|---|
+| `enabled` | `true` | Global switch for all registered checks |
+| `package_allowlist` | `[]` | Regex sources admitting package names; empty admits all |
+| `package_blocklist` | `[]` | Regex sources excluding package names after allowlist matching |
 
-Each entry is a case-sensitive JavaScript regular-expression source compiled with `new RegExp(pattern)`. Matching is unanchored unless the source supplies `^` and `$`; `/pattern/flags` syntax is not parsed. Blank, whitespace-padded, invalid, or duplicate entries within one list fail service startup. A valid pattern may match no currently loaded package so later loading and HMR remain deterministic.
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-invariants) is the exhaustive source for every accepted field and its JSDoc.
 
-`ctx.invariants.register(packageName, installer)` reserves one active registration for the full npm package name, including when filters keep its installer inactive, and returns its disposer. An enabled contribution runs in a dedicated child Cordis fiber. The installer can declare its required services through `installer.inject` and receives `fail(message)`, which throws an `InvariantError` bound to the registering package. Synchronous or asynchronous installer completion is joined before registration succeeds; failure disposes the child and releases ownership atomically.
+### Which checks run
 
-The service owns every registration fiber, while the returned disposer also belongs to the companion fiber. Unloading either side removes listeners, trace state, and the reservation. A companion can therefore reload and register the same package name without retaining its previous state. Session-backed companions rebuild their baseline from durable events; live-only companions observe operations that begin after reload.
-
-`InvariantError` extends `Error`, carries stable `code: 'INVARIANT'`, and exposes the owning `packageName` without adding a product dependency to the service.
-
-Session itself owns immutable, surface-valid log storage in every composition: it takes one lossless JSON snapshot of each candidate, validates complete cited source-event coverage and positional replacement, restricts `tool/result` replacement to one current result's `content`, deep-freezes the accepted record, and exposes the log through immutable array snapshots. The `dsh-session` invariant companion checks the remaining cross-record rules that Session does not own.
-
-## Package companions
-
-Publication and registration are exhaustive; runtime assertions are deliberately not synthetic. A companion installs a check only when its package owns an observable event relationship or relevant mutable-data relationship. Confirming a required method, plugin name, injection, effect, or fixed pure-function result is a type, load, or unit-test concern rather than a runtime invariant.
-
-When no plausible runtime relationship exists, the companion uses an empty installer with a package-specific leading `No runtime invariant:` comment explaining why. This is common for pure utilities, thin implementations whose behavior is already observed through their interface package, composition-only packages, binaries, persistence adapters whose contracts require crash and round-trip tests, and test-support packages. The explanation must be revisited when the owner gains mutable state or an event protocol.
-
-The current executable companions protect these relationships:
+Each companion protects relationships its package owns, and a companion installs a check only for an observable event or mutable-data relationship — never for a service or method presence. The shipped executable companions cover:
 
 | Companion | Checks |
 |---|---|
-| `dsh-session`, `dsh-agent`, `dsh-scope`, `dsh-agent-loop` | Session enclosure and call/result trace, agent-status transitions, inbox FIFO conservation, scoped subjects, and model-request reconstruction. |
-| `dsh-llm`, `dsh-llm-retry`, `dsh-tools`, `dsh-system-prompt` | Stream grammar, durable retry position and bounds, tool-pipeline stages and frozen results, and authoritative prompt-assembly data. |
-| `dsh-compaction`, `dsh-hook-protocol`, `dsh-sandbox-policy` | Durable compaction and hook pairing, compaction metadata, and sandbox-mode vocabulary. |
-| `dsh-fs`, `dsh-subagent`, `dsh-workflow` | Filesystem event identity, provider/child pairing, and workflow/agent lifecycle identity. |
-| `dsh-goal`, `dsh-goal-round-driver` | Durable goal source/content agreement, revision and lifecycle transitions, timestamps, sequential admitted rounds, and reconstructed continuation prompts. |
-| `dsh-permission-presets`, `dsh-user-approval` | Active-preset references and approval asked/decided audit pairing. |
-| `dsh-jobs`, `dsh-tool-todo` | Task snapshot lifecycle/ownership fields and durable whole-list todo structure. |
-| `dsh-time-context` | Durable clock readings agree with the session's open turn and next pre-step position and elapsed baseline; rendered time parses and does not postdate its event. |
+| `dsh-session`, `dsh-agent`, `dsh-scope`, `dsh-agent-loop` | Session log enclosure and call/result trace, agent-status transitions, scope-filtered dispatch subjects, loop-built request reconstruction |
+| `dsh-llm`, `dsh-llm-retry`, `dsh-tools`, `dsh-system-prompt` | LLM stream grammar, retry-failure shape, tool-pipeline stage pairing and frozen results, prompt-assembly section names |

+| `dsh-fs`, `dsh-subagent`, `dsh-workflow`, `dsh-tool-workflow` | Filesystem event identity, subagent provider and start/end pairing, workflow lifecycle identity, workflow record shape |
+| `dsh-goal`, `dsh-goal-round-driver` | Durable goal-stream folds and reconstructed continuation prompts |
+| `dsh-permission-presets`, `dsh-user-approval`, `dsh-commands` | Preset references to live presets, approval asked/decided pairing, command run/done pairing |
+| `dsh-jobs`, `dsh-tool-todo`, `dsh-time-context` | Job snapshot field relationships, whole-list todo shape, durable clock readings |
+| `dsh-credentials`, `dsh-settings`, `dsh-storage-domain`, `dsh-workspace` | Commit events against the live service or memory state, entity-cache mirroring |
+| `dsh-agent-presets`, `dsh-session-title`, `dsh-plan-mode`, `dsh-schedule`, `dsh-webserver` | Preset mount placement, title source citation, plan-mode payload, schedule stream, route disposer symmetry |
+| `dsh-client-hmr`, `dsh-client-modules`, `dsh-client-runtime` | Browser/node-half stat-watcher lifecycle, boot entry graph, slot mutation versioning |
 
-The root entrypoint of each owner remains independent of diagnostics. Loading the service alone installs no product checks, and loading a companion without the service waits on its declared `invariants` injection.
+Every other workspace package publishes an empty companion with a `No runtime invariant:` explanation of why nothing is checkable.
 
-`pnpm run verify-package-invariants` discovers all workspace packages. It rejects generated markers, unexplained empty installers, non-empty installers that omit or ignore the reporter, incorrect registration names, and incomplete export, publication, dependency, TypeScript-reference, or bundle wiring. This source rule is a minimum ownership check; focused tests prove each executable companion's semantics.
+### Adding a companion to a custom composition
 
-## Composition
+A companion is a normal plugin you mount beside the registry. It declares any services it needs and registers under its package's exact npm name; the registry joins its setup before the registration completes.
 
 ```ts
 import type { Context } from '@deepseek-ai/cordis'
@@ -58,28 +81,86 @@ import * as SessionInvariant from '@deepseek-ai/dsh-session/invariant'

-})

 ```
 
-The standard agent composition mounts the service and its four core stateful companions. Custom compositions explicitly add companions for other loaded packages whose contracts they want checked; filters can disable or select registrations without changing package entrypoints.
+### When a check fails
 
-Every ordinary Vitest topology mounts an explicitly enabled service and the current test package's companion. Focused suites cover valid and invalid observations for executable companions, while one exhaustive topology mounts all companions to prove registration and disposal wiring.
+A violation throws an `InvariantError` from the context that reported it: it carries the stable code `INVARIANT`, the full npm `packageName` of the owning package, and a message prefixed `invariant violated by "<package>": …`. The failure is therefore attributable to a package without the registry importing any product code. A companion whose installer itself fails is disposed and its registration rolled back, so a broken check cannot leave partial listeners behind.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design behind the registry; the observable behavior is covered in [Use this package](#use-this-package). The full decision rationale lives in the [invariant-service Agent Note](../../../.agents/notes/implemented/architecture/2026-07-19-package-owned-invariant-service.md).
+
+### Design philosophy
+
+- **Product-independent registry.** The service imports no session, agent, scope, or agent-loop package and contains none of their checks; companions carry checks next to their owners.
+- **Real relationships, not synthetic assertions.** A companion checks an event-stream or mutable-data relationship its package owns; confirming a method, plugin name, injection, or fixed pure result is a type, load, or unit-test concern, never a runtime invariant.
+- **Registration reserves ownership.** A package name is reserved even when filters keep its installer inactive, so two plugins can never silently claim the same name.
+- **Exhaustive wiring, mechanically enforced.** `pnpm run verify-package-invariants` rejects generated markers, unexplained empty installers, non-empty installers that omit or ignore the reporter, wrong registration names, and incomplete export, publication, dependency, or bundle wiring ([contracts note](../../../.agents/notes/implemented/architecture/2026-07-19-package-invariant-runtime-contracts.md)).
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `Config` schema, `InvariantRegistry` service, selection, registration, `InvariantError` |
+| [`src/invariant.ts`](src/invariant.ts) | This package's own companion: an empty installer explaining that registration ownership is the service's own mutation boundary |
+
+### Selection and registration lifecycle
+
+`register(packageName, installer)` reserves the full npm name and returns an effect-scoped disposer. An enabled installer runs in a dedicated child fiber; `installer.inject` declares the services that fiber may access, and synchronous or asynchronous completion is joined before registration succeeds. Failure disposes the child and releases the reservation atomically. The service owns every registration fiber, while the returned disposer also belongs to the companion fiber, so unloading either side removes listeners, trace state, and the reservation — a companion can reload and register the same name again without retained state. Session-backed companions rebuild their baseline from durable events; live-only companions observe operations that begin after reload.

 ## Model Experience
 
-None, as the service and companions observe runtime events and mutable snapshots without altering prompts, messages, schemas, streams, or tool results.
+None, as the observer validates requests but never rewrites their context.
 
 #### KV Cache effect
 
-None; invariant checks do not assemble or send provider requests.
+Checks observe assembled requests and durable state without mutating request content, so provider cache reuse is exactly what the underlying composition produces.
 
 ## Known Limitations and Deferred Work
 
-- Request reconstruction covers requests explicitly marked by the loop before freezing; direct one-shot LLM calls remain outside that marker contract even when callers freeze them or attach a session id.
-- Live-only lifecycle companions cannot reconstruct operations that began before their own reload. Standard and test compositions mount them before the corresponding operations begin.
-- Regular-expression filters are fixed for the service lifetime; changing them requires ordinary Cordis plugin reload.
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define when the registry is a poor fit or needs operational care. They are current package constraints, not a task backlog.
+
+- **Filters are fixed for the service lifetime** — `enabled`, `package_allowlist`, and `package_blocklist` are compiled once at startup; changing them requires a Cordis plugin reload.
+- **Live-only companions miss pre-reload operations** — a companion that only observes live operations cannot reconstruct operations that began before its own reload; session-backed companions rebuild their baseline from durable events.
+- **Request reconstruction covers loop-built requests only** — the `dsh-agent-loop` companion reconstructs requests explicitly built by the loop; direct one-shot LLM calls remain outside that contract even when callers freeze them or attach a session id.
+- **No checks without a companion** — the registry ships no product checks; a composition that mounts the service alone observes nothing.

+## 使用本包
+
+当组合需要验证自身运行时约定时挂载注册表，然后决定运行哪些包的检查。服务暴露 `ctx.invariants`；配套入口以其包的精确 npm 名称注册检查，每次失败都会携带所属包名。
+
+### 何时使用
+
+需要实时诊断的组合请使用注册表。[`agent-spine-demo`](../../../packages/examples/agent-spine-demo/README.zh.md) 中的标准 agent 组合已挂载它及四个核心有状态配套入口——`dsh-session`、`dsh-agent`、`dsh-scope` 与 `dsh-agent-loop`。自定义组合挂载注册表，并为任何其他已加载、且希望检查其约定的包添加配套入口。单独加载注册表不会安装任何检查：它自身不携带任何产品检查，因此从不挂载配套入口的组合不会观察到任何诊断行为。
+
+### 启用检查与选择包
+
+注册表默认启用，并在没有过滤器的情况下检查每个已注册的包。用 `enabled` 作全局开关，用 `package_allowlist` 只接纳指定包，用 `package_blocklist` 在 allowlist 匹配之后排除包——blocklist 匹配优先于 allowlist 匹配。模式是区分大小写的 JavaScript 正则表达式源（除非自带 `^` 与 `$`，否则不锚定）；无效、空白或重复的条目会使服务启动失败，而不是被跳过。
+
+```yaml
+- name: '@deepseek-ai/dsh-invariants'
+  config:
+    enabled: true
+    package_allowlist:
+      - '^@deepseek-ai/dsh-'
 ```
 
-默认值为 `enabled: true`、`package_allowlist: []` 和 `package_blocklist: []`。只有在服务启用、allowlist 为空或至少一个 allowlist pattern 匹配完整 npm 名称，且没有 blocklist pattern 匹配时，包才被选中。因此，blocklist 匹配优先于 allowlist 匹配。
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `enabled` | `true` | 所有已注册检查的全局开关 |
+| `package_allowlist` | `[]` | 接纳包名的正则源；为空则全部接纳 |
+| `package_blocklist` | `[]` | 在 allowlist 匹配之后排除包名的正则源 |
 
-每个条目都是区分大小写的 JavaScript 正则表达式源，使用 `new RegExp(pattern)` 编译。除非源提供 `^` 和 `$`，否则匹配不锚定；不解析 `/pattern/flags` 语法。同一列表中的空白、带前后空白、无效或重复条目会使服务启动失败。有效 pattern 可以不匹配任何当前已加载包，以使后续加载和 HMR（热模块替换）保持确定性。

+### 运行哪些检查
 
-服务拥有每个注册 fiber，返回的 disposer 同时属于配套 fiber。卸载任一侧都会移除监听器、跟踪状态和保留。因此，配套入口可以重新加载并注册同一包名，而不保留旧状态。由会话支撑的配套入口从持久事件重建 baseline；仅实时配套入口观察重新加载后开始的操作。
-
-`InvariantError` 扩展 `Error`，携带稳定 `code: 'INVARIANT'`，并公开所属 `packageName`，而不向服务添加产品依赖。
-
-在每个组合中，Session 自身负责不可变且在对外接口层面有效的日志存储：它对每个候选项制作一份无损 JSON 快照，验证引用的源事件是否齐全以及位置替换是否合法，将 `tool/result` 替换限制为一个当前结果的 `content`，深度冻结已接受记录，并通过不可变数组快照公开日志。`dsh-session` 不变量配套入口检查 Session 不负责的其余跨记录规则。
-
-## 包配套入口
-
-发布和注册覆盖全部包；但不会为了覆盖全部包而人为编造运行时断言。只有当包拥有可观察事件关系或相关可变数据关系时，配套入口才安装检查。确认必需方法、插件名称、注入、effect 或固定纯函数结果属于类型、加载或单元测试关注点，而非运行时不变量。
-
-如果不存在合理的运行时关系，配套入口使用空 installer，并以包专用的前置 `No runtime invariant:` 注释说明原因。纯工具、行为已通过其接口包观察的薄实现、仅组合包、二进制程序、需要通过崩溃测试和往返测试验证其约定的持久化适配器和测试支持包通常属于此类。当 owner 获得可变状态或事件协议时，必须重新审视该说明。
-
-当前可执行配套入口保护以下关系：
+每个配套入口保护其包拥有的关系，且只为可观察的事件或可变数据关系安装检查——绝不针对服务或方法是否存在。已发布的可执行配套入口覆盖：

+
+### 设计理念
+
+- **与产品无关的注册表。** 服务不导入任何 session、agent、scope 或 agent-loop 包，也不包含它们的检查；配套入口把检查放在其归属者旁边。
+- **真实关系，而非人为断言。** 配套入口只检查其包拥有的事件流或可变数据关系；确认方法、插件名、注入或固定纯函数结果是类型、加载或单元测试关注点，绝不是运行时不变量。
+- **注册保留归属。** 即使过滤器让 installer 保持非活动，包名也会被保留，因此两个插件永远不会静默认领同一个名字。
+- **穷尽接线，机械强制。** `pnpm run verify-package-invariants` 拒绝生成标记、未说明的空 installer、省略或忽略 reporter 的非空 installer、错误注册名，以及不完整的导出、发布、依赖或 bundle 接线（[约定笔记](../../../.agents/notes/implemented/architecture/2026-07-19-package-invariant-runtime-contracts.zh.md)）。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：`Config` schema、`InvariantRegistry` 服务、选择、注册、`InvariantError` |
+| [`src/invariant.ts`](src/invariant.ts) | 本包自己的配套入口：一个空 installer，说明注册归属本身就是服务的变更边界 |
+
+### 选择与注册生命周期
+
+`register(packageName, installer)` 保留完整 npm 名称并返回作用域化 disposer。启用的 installer 在专用子 fiber 中运行；`installer.inject` 声明该 fiber 可访问的服务，同步或异步完成都会在注册成功前被 join。失败会释放子级并原子地收回保留。服务拥有每个注册 fiber，返回的 disposer 同时属于配套 fiber，因此卸载任一侧都会移除监听器、跟踪状态与保留——配套入口可以重新加载并再次注册同一名称而不保留旧状态。由会话支撑的配套入口从持久事件重建 baseline；仅实时配套入口观察重新加载后开始的操作。

 ## 模型体验
 
-无。服务和配套入口观察运行时事件和可变快照，不会更改提示词、消息、schema、流或工具结果。
+无。作为观察者，本包验证请求但从不改写其上下文。
 
 #### KV Cache 影响
 
-无；不变量检查不组装或发送提供方请求。
+检查只观察已组装的请求与持久状态，不修改请求内容，因此提供方缓存复用与底层组合产生的结果完全一致。
 
-## 已知限制与暂缓事项
+## 已知限制与延期工作
 
-- 请求重建覆盖 loop 在冻结前显式标记的请求；直接一次性 LLM（大语言模型）调用即使由调用方冻结或附加会话 id，仍不在该标记约定内。
-- 仅实时生命周期配套入口无法重建自身重新加载前开始的操作。标准组合和测试组合会在相应操作开始前挂载它们。
-- 正则表达式过滤器在服务生命周期内固定；更改它们需要执行普通 Cordis 插件重新加载。

+这些限制说明注册表何时不合适或需要特别运维。它们是当前包约束，不是任务积压。
+
+- **过滤器在服务生命周期内固定**——`enabled`、`package_allowlist` 与 `package_blocklist` 在启动时编译一次；更改它们需要执行 Cordis 插件重新加载。

-This family applies per-session confinement policy to process execution. It covers same-world subprocesses; isolated environments replace complete capability implementations instead of registering here.
+## Summary
+
+The `sandbox/` group confines subprocess execution to a file-effect policy: commands run `read-only`, write only under the session workspace (`workspace-write`), or run unrestricted (`danger-full-access`). Four packages deliver it: the confinement service (`sandbox/`), the per-platform backends for Linux, macOS, and Windows (`sandbox-local/`), the shared policy resolver (`sandbox-policy/`), and the Windows write-restriction backend (`sandbox-windows-acl/`). A confined call that a policy denies can retry through a user-approved one-time escalation. Confinement is same-world only: it shares the host kernel and filesystem, while containers, microVMs, and remote executors replace whole capabilities instead of registering here.

 English | [中文](README.zh.md)
 
-Local implementation of the [`dsh-sandbox`](../sandbox/) seam. It selects and caches one platform runner: Linux prefers a working `bwrap` then Landlock; macOS uses Seatbelt; Windows uses the ACL restricted-token runner. Multiple candidates are probed in order, while a sole candidate is selected directly.
+## Summary
 
-The package root exports the default and named `LocalSandboxProvider` plugin and `Config`; platform profile builders stay internal.
+`dsh-sandbox-local` provides the platform confinement backends behind `ctx.sandbox`: Linux runs commands under `bwrap` when that works, otherwise under the Landlock launcher; macOS uses Seatbelt (`sandbox-exec`); Windows uses the ACL restricted-token runner. It selects one runner per host, so every command — and everything it spawns — runs confined. When no runner is usable the provider fails closed with `SANDBOX_UNAVAILABLE` — a command never silently runs unconfined. Each wrap reports how completely the backend enforces the mode (`full` or `partial`) plus the backend's denial signatures, so consumers can tell a broken sandbox apart from a denied command. Mount it behind `ctx.sandbox` with a confined executor to give every bash or pwsh call a confined default.
 
-Unsupported platforms and unusable runners fail closed with `SANDBOX_UNAVAILABLE`; execution never silently falls through unconfined. Each wrap carries structured runner-failure rules so consumers can distinguish a broken sandbox from a command failure.
+## Table of Contents
 
-Policy is per call; the provider stores only the mechanism and cached runner verdict. Each wrap reports enforcement completeness plus backend-specific denial signatures and runner-failure rules. Landlock requires exit 125 and a `landlock-run:` fatal line after excluding only the exact partial-enforcement notice; a notice with child exit 1, 2, or 125 remains a child outcome. Bubblewrap and Seatbelt remain signature-only because neither public contract reserves a launcher-failure status. Consumers spawn the returned argv directly, so a missing or unexecutable runner is an out-of-band spawn failure while a successfully launched child exit 126 or 127 remains ordinary. `runnerCommand` skips probes and requires one or more non-empty, single-line, case-insensitive `runnerFailureSignatures` entries for the custom runner's own fatal dialect. Because its mechanism is unknown, it carries both Linux denial dialects. `probeTimeoutMs` bounds functional probes. The [sandbox Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md) owns selection and failure semantics.

Commands manage descendants but cannot see host processes; hiding host `/proc/<pid>` entries prevents magic links such as `root` and `fd` from bypassing its mounts. `workspace-write` adds ephemeral `/tmp` and a writable workspace bind. The [private-PID Agent Note](../../../.agents/notes/implemented/bug-fix/2026-08-06-bwrap-private-pid-namespace.md) records the boundary.
+-----
 
-The Seatbelt profile is allow-default with `(deny file-write*)` plus write allow-lists, so exactly the mode's promised file effects are governed: `read-only` grants the `/dev/null` literal alone; `workspace-write` adds the workspace root, `/tmp`, and the per-user darwin temp dir (`os.tmpdir()` — the platform's real temp area for mkstemp-family tools), every root canonicalized because Seatbelt matches resolved paths (`/tmp` IS `/private/tmp`). Apple marks the `sandbox-exec` CLI deprecated but ships it on every macOS; the functional probe is what fails closed if that ever changes.

-The Windows rung keeps one deterministic write SID and standing ACE per workspace, but gives every live session/workspace pair a random private temp directory with a distinct SID and revocable ACE. Sessions sharing a workspace therefore share its intended write authority without inheriting one another's temp authority. A fresh provider always chooses a new temp path and SID, so crash residue cannot block or authorize a resumed session; agentless calls receive the same per-invocation isolation from the runner. A workspace equal to or containing the platform temp root fails before any ACL mutation because its inheritable workspace ACE would otherwise reach every private temp child.
+Mount this provider behind `ctx.sandbox` and a confined executor, and every command the executor spawns runs confined under the policy you resolve. The shipped [base bundle](../../bundle/base/cordis.patch.yml) owns the default policy and executor wiring.
 
-[`@deepseek-ai/node-addon-landlock-run`](https://www.npmjs.com/package/@deepseek-ai/node-addon-landlock-run) supplies the platform launcher, functional probe, and CLI argument vocabulary. This provider owns only mode-to-grant mapping and runner selection. Keeping path resolution and probe parsing with the versioned binary prevents contract drift.
+### When to choose it
+
+Choose it when commands must run confined on the host: it is the default backend for Linux, macOS, and Windows compositions that mount `ctx.sandbox`. Choose a different mechanism when the process must run in an isolated environment — a container or remote executor replaces whole capabilities, and this provider shares the host kernel and filesystem.
+
+### Minimal configuration
+
+Load the sandbox service and mount the provider; the defaults below are the selection policy.
 
 ```yaml
 - id: sandbox
   name: '@deepseek-ai/dsh-sandbox-local'
 ```
 
-Consumers: [`@deepseek-ai/dsh-bash-sandbox`](../../shell/bash-sandbox/); the shipped policy/executor wiring lives in the [base bundle](../../bundle/base/cordis.patch.yml).
+| Field | Default | Meaning |
+|---|---|---|
+| `runnerCommand` | `[]` | Custom runner argv; bwrap-compatible profile arguments are appended, full enforcement is asserted, and built-in selection and probes are skipped |
+| `runnerFailureSignatures` | `[]` | Case-insensitive stderr substrings identifying the custom runner's own failure dialect; required with `runnerCommand` |
+| `probeTimeoutMs` | `5,000` | Timeout for each functional probe of a competing runner candidate |
 
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-sandbox-local) is the exhaustive source for every accepted field and its JSDoc.
+
+### Confined execution and enforcement
+
+With the provider mounted, a command runs under the mode you resolve per call. Enforcement is a reported fact, not a promise: `full` means the backend governs every promised file effect, while `partial` means it governs only a subset — the Windows ACL rung (Everyone and hard-link boundaries) and older Landlock ABIs are the current partial cases, so a consumer that requires an absolute boundary can reject or surface them. Denied file effects surface through the backend's denial dialect, and a runner that fails before executing the command reports a structured runner-failure signature.
+
+### Failures and recovery
+
+An unsupported platform or an unusable runner fails closed: `confine()` throws `SANDBOX_UNAVAILABLE` and names the runner options for the platform, and the consumer surfaces that error rather than running the command unconfined. A runner that starts but refuses its profile is identified by its fatal stderr signature and exit code, so a broken sandbox is not mistaken for a denied command. The `runnerCommand` override is an operator assertion: it skips functional probes and assumes the configured runner implements the bwrap-compatible profile honestly.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains runner selection, the per-platform profiles, and the failure dialects; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Runner selection
+
+Selection is by platform first, probes second: each platform has a runner chain (`linux`: `bwrap` then Landlock; `darwin`: Seatbelt; `win32`: the ACL restricted-token runner). A sole candidate is selected without a probe; competing candidates are functionally probed once in chain order, and the first usable verdict is cached for the provider's lifetime. A platform with no chain, or a chain where every probe fails, is unavailable and fails closed at `confine()`.
+
+### Platform profiles
+
+The bwrap profile combines a read-only host root, a fresh `/dev`, and `/proc` from a private PID namespace — commands manage their descendants but cannot see host processes, so procfs magic links cannot bypass the mounts; `workspace-write` adds an ephemeral `/tmp` and a writable workspace bind. The [private-PID note](../../../.agents/notes/implemented/bug-fix/2026-08-06-bwrap-private-pid-namespace.md) records the boundary.
+
+The Landlock launcher ships as an npm-distributed native addon (`@deepseek-ai/node-addon-landlock-run`) that supplies the platform launcher, functional probe, and grant vocabulary; this provider maps mode to grants only, keeping path resolution and probe parsing with the versioned binary.
+
+The Seatbelt profile is allow-default with `(deny file-write*)` plus write allow-lists derived from the shared `writableRoots` helper, so exactly the mode's promised file effects are governed; every root is canonicalized because Seatbelt matches resolved paths (`/tmp` IS `/private/tmp`).
+
+The Windows rung keeps one deterministic write SID and standing ACE per workspace, while every live session/workspace pair gets a random private temp directory with a distinct SID and revocable ACE — sessions sharing a workspace share its intended write authority without inheriting one another's temp authority. A fresh provider always chooses a new temp path and SID, so crash residue cannot block or authorize a resumed session. The rung reports `partial` enforcement because the restricted token must retain Everyone and NTFS hard links alias one file object across paths.
+
+### Denial and runner-failure dialects
+
+Each runner's kernel speaks its own denial dialect, carried on every wrap as `denialSignatures`, and `runnerFailureRules` give each runner's fatal signature, so consumers classify a runner refusal before checking denial signatures. The exact strings and exit codes live in [`src/index.ts`](src/index.ts).
+
+### Source map

+| [`src/index.ts`](src/index.ts) | Plugin entry: runner chain selection, functional probes, per-call wrap, ACL grant lifecycle |

 ## Known Limitations and Deferred Work
 
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define when the provider is a poor fit or needs special operational care. They are current package constraints, not a general platform comparison or a task backlog.
+
 - **Windows ACL enforcement is partial** — the restricted token must retain Everyone for process initialization, so external objects granting Everyone write access remain writable; NTFS hard links also alias one file object across workspace and external paths. The provider reports `enforcement: 'partial'` rather than overstating that boundary as full.
 - **Landlock may be partial** — older supported kernel ABIs confine only the access classes they expose, reported as `enforcement: 'partial'` rather than overstated as full.
 - **Seatbelt depends on deprecated `sandbox-exec`** — macOS still ships it, but this provider cannot replace or probe that private policy engine if Apple removes it.
 - **Runner selection is cached for the provider lifetime** — installing, removing, or repairing a runner requires reloading the plugin before selection changes.
 - **`runnerCommand` is an operator assertion** — a configured custom runner skips functional probes and is assumed to implement the bwrap-compatible profile honestly; if it is itself a Bash script, its interpreter startup runs before that script applies confinement.

-[`dsh-sandbox`](../sandbox/) seam 的本地实现。它选择并缓存一个平台 runner：Linux 优先选择可工作的 `bwrap`，否则选择 Landlock；macOS 使用 Seatbelt；Windows 使用 ACL 受限令牌 runner。多个候选项会按顺序探测，只有一个候选项时则直接选择。
+## 概述
 
-包根目录导出默认及命名的 `LocalSandboxProvider` 插件和 `Config`；平台 profile builder 仍为内部实现。
+`dsh-sandbox-local` 提供 `ctx.sandbox` 背后的平台隔离后端：Linux 在 `bwrap` 可用时用其运行命令，否则使用 Landlock launcher；macOS 使用 Seatbelt（`sandbox-exec`）；Windows 使用 ACL 受限令牌 runner。它每台主机选择一个 runner，因此每条命令及其派生的所有进程都在限制下运行。没有可用 runner 时，提供方以 `SANDBOX_UNAVAILABLE` 快速失败——命令绝不会静默无限制运行。每次包装都会报告后端对模式的强制执行完整度（`full` 或 `partial`）及后端的拒绝签名，因此消费方可以区分损坏的沙箱与被拒绝的命令。在 `ctx.sandbox` 后挂载它并配一个受限执行器，即可让每次 bash 或 pwsh 调用都有受限默认值。
 
-不受支持的平台和不可用 runner 会以 `SANDBOX_UNAVAILABLE` 拒绝执行；执行绝不会静默回退为不受限制。每次包装都携带结构化 runner 失败规则，使消费方能够区分损坏的沙箱与命令失败。
+## 目录
 
-策略逐调用传入；提供方只存储机制与缓存的 runner 结论。每次包装都会报告强制执行完整度，以及后端专用的拒绝签名和 runner 失败规则。Landlock 只有在退出码为 125，且仅排除完全匹配的部分强制执行通知后仍存在一行 `landlock-run:` 致命诊断时，才判定 runner 失败；携带该通知的子进程即使以 1、2 或 125 退出，也仍按子进程结果处理。Bubblewrap 和 Seatbelt 仍仅依据签名，因为两者的公开约定均未保留 launcher 失败状态。消费方会直接 spawn 返回的 argv，因此 runner 缺失或不可执行属于带外 spawn 失败，而成功启动的子进程以 126 或 127 退出时仍按普通结果处理。`runnerCommand` 会跳过探测，并要求为自定义 runner 自身的致命方言提供一个或多个非空、单行、不区分大小写的 `runnerFailureSignatures` 条目。由于其机制未知，它会同时携带两种 Linux 拒绝方言。`probeTimeoutMs` 限定功能探测的时长。[沙箱 Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.zh.md) 负责说明选择与失败语义。

-bwrap profile 将只读宿主根目录、全新的 `/dev` 与使用私有 PID 命名空间的 `/proc` 组合起来。命令可管理后代进程，但看不到宿主进程；隐藏宿主的 `/proc/<pid>` 条目，可以防止 `root`、`fd` 等魔法链接绕过其挂载约束。`workspace-write` 另加临时的 `/tmp` 与可写工作区绑定挂载。[私有 PID Agent Note](../../../.agents/notes/implemented/bug-fix/2026-08-06-bwrap-private-pid-namespace.zh.md)记录该边界。
+-----
 
-Seatbelt profile 默认允许，但带 `(deny file-write*)` 和写入 allow-list，因此恰好约束相应模式承诺的文件操作：`read-only` 只授予 `/dev/null` 字面路径；`workspace-write` 另加工作区根目录、`/tmp` 和逐用户 darwin 临时目录（`os.tmpdir()`，即平台供 mkstemp 家族工具使用的真实临时区域）。每个根目录都经过规范化，因为 Seatbelt 匹配解析后的路径（`/tmp` 就是 `/private/tmp`）。Apple 将 `sandbox-exec` CLI（命令行界面）标为 deprecated，但所有 macOS 系统仍会提供它；若情况发生变化，功能探测会使执行被拒绝。
+<a id="use-this-package"></a>
+## 使用本包
 
-Windows 档为每个工作区保留一个确定性写入 SID 和常驻 ACE，但为每个活跃的会话/工作区对分配一个随机私有临时目录，以及不同的 SID 和可撤销 ACE。因此，共享工作区的会话会共享预期的写权限，却不会继承彼此的临时目录权限。新的提供方总会选择新的临时路径和 SID，因此崩溃残留既无法阻止恢复的会话，也无法向其授权；runner 会为无 agent（智能体）的调用提供同样的逐调用隔离。如果工作区等于或包含平台临时根目录，调用会在任何 ACL 改动发生前失败，因为否则其可继承的工作区 ACE 会延伸到每个私有临时子目录。
+在 `ctx.sandbox` 后挂载此提供方并配一个受限执行器，执行器 spawn 的每条命令都会在你解析的策略下受限运行。随附的 [base bundle](../../bundle/base/cordis.patch.yml)拥有默认策略与执行器接线。
 
-[`@deepseek-ai/node-addon-landlock-run`](https://www.npmjs.com/package/@deepseek-ai/node-addon-landlock-run) 提供平台 launcher、功能探测和 CLI 参数词汇。该提供方只负责模式到授权的映射与 runner 选择。把路径解析和探测解析保留在带版本的 binary 中，可防止约定漂移。
+### 何时选择
+
+当命令必须在宿主机上受限运行时选择它：它是挂载 `ctx.sandbox` 的 Linux、macOS 与 Windows 组合的默认后端。当进程必须在隔离环境中运行时请另选机制——容器或远程执行器会替换整个能力，而此提供方与宿主共享内核和文件系统。
+
+### 最小配置
+
+加载沙箱服务并挂载提供方；以下默认值即选择策略。
 
 ```yaml
 - id: sandbox
   name: '@deepseek-ai/dsh-sandbox-local'
 ```
 
-消费方：[`@deepseek-ai/dsh-bash-sandbox`](../../shell/bash-sandbox/)；交付的策略／执行器接线位于 [base bundle](../../bundle/base/cordis.patch.yml)。
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `runnerCommand` | `[]` | 自定义 runner argv；会追加 bwrap 兼容的 profile 参数，断言完全强制执行，并跳过内置选择与探测 |
+| `runnerFailureSignatures` | `[]` | 识别自定义 runner 自身失败方言的不区分大小写 stderr 子串；与 `runnerCommand` 搭配必需 |
+| `probeTimeoutMs` | `5,000` | 每次竞争 runner 候选功能探测的超时时间 |
 
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-sandbox-local)是每个受支持字段及其 JSDoc 的穷尽式真源。
+
+### 受限执行与强制执行
+
+挂载提供方后，命令在你逐调用解析的模式下运行。强制执行是报告的事实，而非承诺：`full` 表示后端管辖模式承诺的每个文件操作，`partial` 表示它只管辖子集——Windows ACL 档（Everyone 与硬链接边界）与较旧的 Landlock ABI 是当前的部分强制执行情形，因此需要绝对边界的消费方可以拒绝或向上暴露它们。被拒绝的文件操作通过后端的拒绝方言呈现，执行命令前失败的 runner 会报告结构化的 runner 失败签名。
+
+### 失败与恢复
+
+不受支持的平台或不可用的 runner 会快速失败：`confine()` 抛出 `SANDBOX_UNAVAILABLE` 并列出该平台的 runner 选项，消费方会呈现该错误，而不是让命令不受限制地运行。启动后拒绝自身 profile 的 runner 由其致命 stderr 签名与退出码识别，因此损坏的沙箱不会被误认为被拒绝的命令。`runnerCommand` 覆盖是操作方断言：它跳过功能探测，并假定配置的 runner 诚实实现与 bwrap 兼容的 profile。

+<summary>实现细节——点击展开</summary>
+
+本节解释 runner 选择、各平台 profile 与失败方言；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### runner 选择
+
+选择按平台优先、探测其次：每个平台都有 runner 链（`linux`：`bwrap` 再 Landlock；`darwin`：Seatbelt；`win32`：ACL 受限令牌 runner）。唯一候选直接选择、不探测；竞争候选按链序各执行一次功能探测，首个可用结论在提供方生命周期内缓存。没有链的平台、或链上所有探测都失败时，平台不可用，并在 `confine()` 处快速失败。
+
+### 平台 profile
+
+bwrap profile 组合只读宿主根目录、全新 `/dev` 与私有 PID 命名空间中的 `/proc`——命令可管理其后代，但看不到宿主进程，因此 procfs 魔法链接无法绕过挂载；`workspace-write` 另加临时的 `/tmp` 与可写工作区绑定挂载。[私有 PID 笔记](../../../.agents/notes/implemented/bug-fix/2026-08-06-bwrap-private-pid-namespace.zh.md)记录该边界。
+
+Landlock launcher 以 npm 分发的原生插件（`@deepseek-ai/node-addon-landlock-run`）提供平台 launcher、功能探测与授权词汇；此提供方只做模式到授权的映射，把路径解析与探测解析保留在带版本的 binary 中。
+
+Seatbelt profile 默认允许，带 `(deny file-write*)` 与来自共享 `writableRoots` 辅助函数的写入 allow-list，因此恰好管辖模式承诺的文件操作；每个根目录都经过规范化，因为 Seatbelt 匹配解析后的路径（`/tmp` 就是 `/private/tmp`）。
+
+Windows 档为每个工作区保留一个确定性写入 SID 和常驻 ACE，同时为每个活跃的会话/工作区对分配一个随机私有临时目录，以及不同的 SID 和可撤销 ACE——共享工作区的会话共享其预期写权限，却不会继承彼此的临时目录权限。新的提供方总会选择新的临时路径和 SID，因此崩溃残留既无法阻止恢复的会话，也无法向其授权。该档报告 `partial` 强制执行，因为受限令牌必须保留 Everyone，且 NTFS 硬链接会把同一文件对象别名为多个路径。
+
+### 拒绝与 runner 失败方言
+
+每个 runner 的内核都有自己的拒绝方言，随每次包装以 `denialSignatures` 携带，`runnerFailureRules` 则给出每个 runner 的致命签名，因此消费方先分类 runner 拒绝，再检查拒绝签名。精确的字符串与退出码位于 [`src/index.ts`](src/index.ts)。
+
+### 源码地图

A deployment sets a default mode and a fallback workspace root; a session can switch its own mode, and the switch survives restart because it lives in the session log. Every enforcing capability — bash, filesystem, terminal — reads the same resolved policy, so the mode a call runs under never depends on which family resolved it. The model sees one concise `sandbox:policy` contribution naming the mode and workspace, without a separate inventory of mounted capabilities.
 
-Filesystem tools, one-shot bash commands, and terminal sessions may enforce the same mode vocabulary in different combinations. If each resolved its own `mode` + `workspaceRoot`, they could drift into a split world, exactly what [the sandbox Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md) warns against. Each enforcing backend consumes the complete owner-resolved policy, while the current context describes only what that policy means for any available operation the DSH file sandbox enforces. The [cross-family fs sandbox Agent Note](../../../.agents/notes/implemented/feature/2026-07-14-cross-family-fs-sandbox.md) records the shared-policy decision.

+## Use this package
 
-- `ctx.sandboxPolicy.resolve({ session?, mode? })` — resolves one complete per-call policy. An explicit approved mode outranks the session's last `sandbox/mode` event, which outranks `defaultMode`; the session's immutable `cwd` is canonicalized with filesystem semantics before becoming `workspaceRoot`, otherwise the configured fallback applies. Canonicalization precedes lexical normalization so `symlink/..` agrees with process working-directory resolution.
-- `ctx.sandboxPolicy.defaultMode` / `ctx.sandboxPolicy.workspaceRoot` — the deployment default and fallback root used by `resolve()`.
-- `sandbox:policy` — a request-time cache-safe context contribution derived directly from `resolve({ session })`. It states the mode's capability-neutral file-effect contract and the canonical session workspace under `workspace-write`; tool owners retain operation-specific denial and escalation guidance.
-- `effectiveSandboxMode(events)` — the pure fold of a session's `sandbox/mode` events (the last switch wins, or `undefined`), used inside `resolve()`.
-- `setSandboxMode(session, mode)` — THE write path for a per-session override: appends exactly one `sandbox/mode` event. The switch IS its event; nothing mutates the mode out of band.
-- `SANDBOX_MODES` — every mode, for option advertisement and runtime validation.
+Mount this package in any composition where sandbox-enforcing capabilities run: it owns the deployment default and the per-session overrides those capabilities consume, and it contributes the current policy to the model's runtime-context snapshot.
 
-The optional `./invariant` companion rejects a forged durable `sandbox/mode` event whose value falls outside that closed vocabulary; Session and its companion own the surrounding storage and core execution-enclosure rules. The agent loop logs the assembled full runtime-context snapshot as a sourced `user/message`, so exact policy input remains reconstructable without an in-memory “last told” mirror.
+### When to choose it
 
-## The per-session store
+Choose it for every composition with confined capabilities (bash, filesystem, terminal) so one policy home keeps them from drifting into different modes or workspace roots. Skip it only when nothing enforces sandbox policy — with no consumers, the resolved policy has no effect.
 
-A runtime switch is one log-only `sandbox/mode` event on the session it applies to. `effective = explicit grant ?? fold(events) ?? deployment default`, so an override survives restart by replay and two sessions never see each other's state. Workspace identity does not need another event: the immutable `SessionHeader.cwd` recorded at creation is the root for every call in that session. The event stays log-only; before the next request, the owner contributes the current fact to the full runtime-context snapshot.
+### Minimal configuration
 
+Load the package with a default mode; the fail-safe default is `read-only`, and a deployment that wants a workspace-writable agent opts into `workspace-write` explicitly.
+
+```yaml
+- name: '@deepseek-ai/dsh-sandbox-policy'
+  config:
+    mode: workspace-write
+    workspaceRoot: /absolute/path/to/workspace
+```
+
+| Field | Default | Meaning |
+|---|---|---|
+| `mode` | `read-only` | The deployment default mode a session starts from, validated at load |
+| `workspaceRoot` | `process.cwd()` | The fallback root `workspace-write` may write under for agentless calls or sessions without a cwd; normal agent calls use the session's immutable cwd instead |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-sandbox-policy) is the exhaustive source for every accepted field and its JSDoc.
+
+### Switching a session's mode
+
+A session's mode can be switched at runtime through a UI policy control or an explicit switch; the switch is recorded in the session log and takes effect on the session's next confined call. The switch survives restart through replay, and each session keeps its own mode — two sessions never see each other's state. A switched session keeps its immutable workspace cwd as the writable boundary.
+
+### Failures and recovery
+
+An invalid configured mode is rejected when the plugin loads, so a typo fails loud instead of silently changing policy. A session without a cwd, and agentless calls, fall back to the configured workspace root; a call with an approved explicit mode uses that mode for exactly that call.

+This section explains policy resolution, the per-session store, and the model-visible contribution; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Resolution precedence
+
+`resolve({ session, mode })` returns one complete per-call policy: an approved explicit mode outranks the session's last `sandbox/mode` event, which outranks the deployment default. The session's immutable `cwd` is canonicalized with filesystem semantics before becoming the workspace root, so `symlink/..` agrees with process working-directory resolution; otherwise the configured fallback applies.
+
+### The per-session store
+
+A runtime switch is one log-only `sandbox/mode` event on the session it applies to — the switch IS its event, and nothing mutates mode state out of band. `effective = explicit grant ?? fold(events) ?? deployment default`, so an override survives restart by replay and two sessions never see each other's state. Workspace identity needs no event: the immutable `SessionHeader.cwd` recorded at creation is the root for every call in that session. The event stays log-only; before each request, the owner contributes the current fact to the full runtime-context snapshot, and the agent loop logs that snapshot as a sourced `user/message`.
+
+### Model-visible text
+
+The `sandbox:policy` contribution states the mode's capability-neutral file-effect contract and the canonical session workspace under `workspace-write`. It does not enumerate mounted capabilities; tool plugins retain operation-specific denial and escalation guidance, approval policy contributes separately to the same snapshot, and plan guidance remains `dsh-plan-mode`'s system section. The optional `./invariant` companion rejects a forged durable `sandbox/mode` event whose value falls outside the closed mode vocabulary.

-沙箱策略解析的唯一归属位置：部署默认 [`SandboxMode`](../sandbox/README.zh.md) 与回退根目录，加上每个会话的持久模式覆盖和不可变工作区根目录。每项负责强制执行的能力在每次调用时都会收到一项解析完成的模式与根目录策略；模型在每次请求前会收到当前策略，而不会另收一份能力清单。
+## 概述
 
-## 为何需要共享归属位置
+`dsh-sandbox-policy` 为每次受限能力调用从统一的策略归属位置解析文件效果模式与工作区根目录，并在每次请求前把当前策略告知模型。部署方设置默认模式与回退工作区根目录；会话可以切换自己的模式，切换因存在于会话日志中而跨重启保留。每个强制执行能力——bash、文件系统、终端——读取同一份解析出的策略，因此调用运行的模式绝不取决于由哪个家族解析。模型会看到一条简洁的 `sandbox:policy` 贡献，指明模式与工作区，而不会收到一份已挂载能力的清单。
 
-文件系统工具、一次性 bash 命令和终端会话可以用不同组合强制执行同一套模式词汇。如果各自解析 `mode` + `workspaceRoot`，就可能漂移成分裂世界，正是[沙箱 Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.zh.md)所警告的情况。每个强制执行后端都会消费归属方解析出的完整策略，而当前上下文只说明该策略对于任何受 DSH 文件沙箱强制执行的可用操作有何含义。[跨家族 fs 沙箱 Agent Note](../../../.agents/notes/implemented/feature/2026-07-14-cross-family-fs-sandbox.zh.md)记录了共享策略决策。

+### 何时选择
 
-## 逐会话存储
+为每个带受限能力（bash、文件系统、终端）的组合选择它，让单一策略归属位置防止它们漂移到不同的模式或工作区根目录。只有没有任何沙箱策略强制执行时才跳过它——没有消费方时，解析出的策略不起作用。
 
-运行时切换是在对应会话日志中追加的一条 `sandbox/mode` 事件。`effective = explicit grant ?? fold(events) ?? deployment default`，因此覆盖会通过回放跨重启保留，两个会话也绝不会看到彼此状态。工作区标识无需另一条事件：创建时记录的不可变 `SessionHeader.cwd` 是该会话每次调用使用的根。该事件仍只进入日志；在下一次请求前，归属方会将当前事实贡献给完整运行时上下文快照。
+### 最小配置
 
+用默认模式加载本包；故障安全默认值是 `read-only`，想要可写工作区 agent 的部署需要显式选择 `workspace-write`。
+
+```yaml
+- name: '@deepseek-ai/dsh-sandbox-policy'
+  config:
+    mode: workspace-write
+    workspaceRoot: /absolute/path/to/workspace
+```
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `mode` | `read-only` | 会话起始的部署默认模式，加载时验证 |
+| `workspaceRoot` | `process.cwd()` | 无 agent（智能体）调用或没有 cwd 的会话在 `workspace-write` 下可写入的回退根目录；普通 agent 调用改用会话的不可变 cwd |
+
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-sandbox-policy)是每个受支持字段及其 JSDoc 的穷尽式真源。
+
+### 切换会话模式
+
+会话的模式可以在运行时通过 UI 策略控件或显式切换来更改；切换记录在会话日志中，并在该会话的下一次受限调用时生效。切换通过回放跨重启保留，每个会话保持自己的模式——两个会话绝不会看到彼此状态。切换后的会话继续以不可变的工作区 cwd 作为写入边界。
+
+### 失败与恢复
+
+无效的配置模式会在插件加载时被拒绝，因此拼写错误会大声失败，而不是静默改变策略。没有 cwd 的会话与无 agent 调用回退到配置的工作区根目录；带已批准显式模式的调用只在该次调用中使用该模式。

-Windows write-restriction sandbox backend for the [harness sandbox seam](../sandbox/): a Node.js/[koffi](https://koffi.dev/) port of the mechanism in [huoyaoyuan/windows-acl-restrict-poc](https://github.com/huoyaoyuan/windows-acl-restrict-poc) (`10e4dfb`, the fixed revision), mounted as the `enforcement: 'partial'` win32 rung of the [`@deepseek-ai/dsh-sandbox-local`](../sandbox-local/) chain (`workspace-write` / `read-only` modes); the same package carries the Linux/macOS backends.
+## Summary
 
-Mechanism in one line: the caller's token is duplicated into a `WRITE_RESTRICTED` token whose restricting SIDs carry separate workspace and private-temp capabilities. The workspace SID is derived deterministically from the canonical workspace path (`workspaceWriteSid`), so the workspace-root ACE materializes once per workspace per machine and every later session, call, or restart hits the exact-ACE skip. Each live session/workspace pair instead receives a random temp directory and a SID derived from that path (`tempWriteSid`), so sessions share the intended workspace authority without inheriting one another's temp authority. Windows grants a write only where BOTH the caller's normal access AND the restricting-SID intersection allow it. These SIDs are the primary allowlists and grant nothing elsewhere, but the check also inherits ambient write ACEs of the OTHER restricting SIDs (the keep-alive group logon SID + Everyone), and NTFS ACLs belong to file objects rather than paths; the Everyone and hard-link boundaries are why the rung reports partial rather than full enforcement.
+`dsh-sandbox-windows-acl` confines Windows processes by write restriction: a child runs under a restricted token whose write access is limited to the workspace and a private temp directory, so `workspace-write` allows those writes and `read-only` allows none. It ships as the win32 rung of `dsh-sandbox-local`: mounting the local provider on Windows gives every confined bash or pwsh call this backend automatically. It can also be embedded directly through the `AclSandbox` API to spawn confined children with captured stdio. Every Win32 call is checked and failures throw, so a child is never spawned unrestricted. Enforcement is partial by design — the restricted token must retain Everyone for process initialization, and NTFS hard links can alias one file object across paths — so the backend reports `partial` and callers that need the absolute boundary can surface it.
 
-Building directly on the raw ACL mechanism is the recorded design choice: it implements both confinement modes without the problems the rejected container options carry — see the [design note](../../../.agents/notes/implemented/feature/2026-08-08-windows-acl-restricted-token-sandbox.md) ([mxc](https://github.com/microsoft/mxc/blob/main/docs/process-container/os-version-support.md) needs an OS floor of Windows 11 24H2 and wholesale host DACL writes for arbitrary-path reads; AppContainer cannot do arbitrary-path reads at all).

+## Use this package
+
+On Windows, mounting the local sandbox provider makes this backend the runner behind `ctx.sandbox` — no extra configuration. Embed the `AclSandbox` API directly when you spawn confined children outside the harness.
+
+### When to choose it
+
+Choose it for Windows compositions that confine subprocess file effects under `read-only` or `workspace-write`. Choose a different mechanism when the child must also be read-confined or network-restricted: `WRITE_RESTRICTED` intersects write accesses only, so pair this backend with a read-side policy or an AppContainer capability token for stronger confinement.
+
+### Direct API
+
+`AclSandbox` spawns a confined child with captured stdio (or inherited stdio for runner-style use). It requires an explicit private temp directory, or `tempDir: null` to disable temp writes — the ambient temp root is never an implicit grant.

-A direct `AclSandbox` requires an explicit private temp directory (or `tempDir: null`; the ambient temp root is never an implicit grant), grants the workspace ACEs STANDING (dispose() leaves them — they are the cross-instance reuse cache), and grants the distinct temp SID revocably. The server-side reuse is the `AclWriteGrant` class: `add(path, standing)` per directory, `dispose()` revokes the revocable paths and frees the SID — see the runner contract below. Every policy-specific Win32 call and every process primitive from [`dsh-win32-process`](../../subprocess/win32-process/README.md) is checked; failures throw `Win32Error` carrying the API name, the exact Win32 code, the `FormatMessageW` system text, and the failing path/context. This is deliberate: the POC ignored every return value and, when `CreateRestrictedToken` failed, silently ran the child with the FULL unrestricted token (fail-open). This port fails closed by construction.
+The workspace ACEs are granted standing — `dispose()` leaves them, because they are the cross-instance reuse cache — while the distinct temp SID is granted revocably. The server-side counterpart is the `AclWriteGrant` class: `add(path, standing)` per directory, and `dispose()` revokes the revocable paths and frees the SID.
 
-## The confinement runner
+### What confinement gives you
 
-The seam-facing shape is the **runner entry** (`./runner`), the argv-prefix wrapper `@deepseek-ai/dsh-sandbox-local` spawns in place of the caller's command — the same architecture as bwrap/landlock-run/sandbox-exec, so the sandbox seam's `confine()` contract needs no change. Stable argv contract:
+Under `workspace-write`, the child may write into the workspace and its private temp directory; other ACL-addressable writes are denied except the documented Everyone and hard-link boundaries. Under `read-only`, no explicit write grants exist, so writes are denied with the same documented ambient boundaries.
+
+Temp isolation is per live session/workspace pair: sessions sharing a workspace share its write authority but cannot write one another's temp directories. A fresh provider always chooses a new temp path and SID, so crash residue cannot block or authorize a resumed session.
+
+### Failures and recovery
+
+`init()` throws on any Win32 failure — the child is never spawned unrestricted. A runner that fails before executing the command prints `windows-acl-run: <detail>` to stderr and exits 127, which the seam's runner-failure rules classify as a broken sandbox rather than a denial. Cleanup is best-effort by design: `dispose()` attempts every temp revocation and aggregates failures into an `AggregateError`.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the restricted-token mechanism, the token lists, the runner contract, and the verified boundaries; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Mechanism
+
+The caller's token is duplicated into a `WRITE_RESTRICTED` token whose restricting SIDs carry separate workspace and private-temp capabilities. Windows performs the access check twice — once against the normal SIDs, once against the restricting SIDs — and grants write-class access only where both checks pass. The workspace SID is derived deterministically from the canonical workspace path (`workspaceWriteSid`), so the workspace-root ACE materializes once per workspace per machine and every later session, call, or restart hits the exact-ACE skip. Each live session/workspace pair instead receives a random private temp directory and a SID derived from that path (`tempWriteSid`), so sessions share the intended workspace authority without inheriting one another's temp authority. Every policy-specific Win32 call and every process primitive from [`dsh-win32-process`](../../subprocess/win32-process/README.md) is checked; failures throw `Win32Error` carrying the API name, exact code, system text, and failing context — fail-closed by construction.
+
+### Modes and token lists
+
+`workspace-write` (logon SID, Everyone, workspace SID, temp SID) grants the workspace and the session's private temp subdirectory separate Write grants; `read-only` (logon SID, Everyone — no write SID) grants none. The keep-alive group (logon SID + Everyone) is present in both modes: without it, early DLL initialization dies with `0xC0000142` and CNG crashes pwsh with `0xE0434352`. The write SID stays out of the read-only list on purpose: the standing workspace grant from an earlier workspace-write period remains inert because the write-restricted pass-2 check grants only what the restricting list carries, while the standing ACE keeps a re-upgrade free of re-propagation.
+
+NUL writes are ambient, not granted: the device DACL grants Everyone read+write+execute (`0x1201BF`), so openers whose mask fits it (cmd `> NUL`, node `\\.\NUL`) can write it in both modes. `Set-Content NUL` fails in both modes (a PowerShell/.NET-layer effect, not the device DACL), while PowerShell's `> $null` redirection keeps working.
+
+Authenticated Users is absent from both lists — the WMI namespace security check fails (`0x80041003`), so CIM cmdlets and `Get-ComputerInfo` are unavailable in every confined mode, and the C:\-root tree-creation escape is closed. INTERACTIVE/LOCAL are absent too: the host's Public tree grants write to INTERACTIVE, so Public writes are denied.
+
+### The confinement runner
+
+The seam-facing shape is the runner entry (`./runner`): an argv-prefix wrapper `dsh-sandbox-local` spawns in place of the caller's command, with the same architecture as bwrap/landlock-run/sandbox-exec. The runner creates the restricted token, spawns the wrapped argv under it with the caller's stdio passed straight through, wraps the child in a `KILL_ON_JOB_CLOSE` job, mirrors the child's exit code, and revokes its self-managed temp grant on exit. Every runner-side failure prints `windows-acl-run: <detail>` to stderr and exits 127 — the seam's runner-failure rules match that signature.
 
 ```sh
 node runner.js --workspace <dir> --temp <dir> --mode <read-only|workspace-write> [--write-sid <S-1-4-…> --temp-write-sid <S-1-4-…>] -- <argv...>
 ```
 
-The runner creates the restricted token, spawns the wrapped argv under it with the caller's stdio passed straight through (the caller's pipes, made inheritable around the spawn — Node clears stdio inheritability at startup, which raw spawns must compensate for), wraps the child in a `KILL_ON_JOB_CLOSE` job (a dead runner kills the child), ignores its own console Ctrl+C so the child handles its own, mirrors the child's exit code, and revokes its self-managed temp grant on exit (workspace ACEs stand). Every runner-side failure prints `windows-acl-run: <detail>` to stderr and exits 127 — the seam's `RUNNER_FAILURE_RULES` match that signature, so a runner refusal is never mistaken for a denial.
+The seam materializes the deterministic workspace SID's ACE standing (once per workspace per server lifetime — the reuse cache), then creates a random private temp directory and a distinct revocable SID for each live session/workspace pair, passing both as the required `--write-sid`/`--temp-write-sid` pair; the runner verifies each against its owning path and neither grants nor revokes (`manageDacls: false`). A fork receives a different temp capability, and a fresh provider gives even the same resumed session a new path and SID, so crash residue is inert litter. Without the pair, `--temp` names a root: an agentless workspace-write runner creates a random private child, self-manages its temp SID, rewrites TMP/TEMP, and removes the child on exit. Re-granting the standing workspace ACE after a restart is idempotent: `grantWrite` reads the current DACL and skips the re-propagation when the exact ACE already stands. A workspace equal to or containing the temp root is rejected before any grant.
 
-**Workspace reuse and temp isolation**: the seam materializes the deterministic workspace SID's ACE STANDING (once per workspace per server lifetime, never revoked — it is the reuse cache), then creates a random private temp directory and distinct revocable SID for each live session/workspace pair. It passes both identities as the required `--write-sid`/`--temp-write-sid` pair; the runner verifies each against its owning path and neither grants nor revokes (`manageDacls: false`). A fork receives a different temp capability, and a fresh provider gives even the same resumed session a new path and SID, so crash residue is inert litter rather than a collision or inherited capability. Without the pair, `--temp` names a root: an agentless/standalone workspace-write runner creates a random private child, self-manages its temp SID, rewrites TMP/TEMP, and removes the child on exit. A workspace equal to or containing that root is rejected before any grant because its inheritable workspace ACE would otherwise authorize every private child; the direct API likewise rejects overlap between any writable root and the actual private temp directory. Re-granting the standing workspace ACE after a restart is idempotent: `grantWrite` reads the current DACL and skips `SetNamedSecurityInfoW` when the exact ACE already stands (that apply eagerly re-propagates the identical ACE across the whole tree — minutes on large workspaces). Known cost: the first grant on a big workspace tree blocks for that eager propagation once per workspace per machine.
+### Verified boundaries
 
-Modes (the token's restricting-SID list follows the mode; the keep-alive group is logon SID + Everyone in BOTH modes — early DLL init dies with `0xC0000142` and CNG crashes pwsh with `0xE0434352` without them):
-- `workspace-write` (logon SID, Everyone, workspace SID, temp SID): the workspace and the session's PRIVATE temp subdirectory carry separate Write grants; other ACL-addressable writes are denied except for the documented Everyone and hard-link boundaries.
-- `read-only` (logon SID, Everyone — NO write SID): no explicit write-SID grants. The write SID stays OUT of the list on purpose: the standing workspace grant ACE from an earlier workspace-write period (a `/permission` downgrade, or a crash-resumed session) remains INERT under read-only because the write-restricted pass-2 check grants only what the restricting list carries — while the standing ACE keeps the re-upgrade free of re-propagation. Everyone's ambient rights remain the documented partial boundary. NUL writes are AMBIENT, not granted: the device DACL grants Everyone read+write+execute (`0x1201BF`), so openers whose mask fits it (cmd `> NUL`, node `\\.\NUL`) can write it in BOTH modes — the sandbox cannot zero-grant the NUL device while Everyone stays in the keep-alive group. `Set-Content NUL` fails in both modes (a PowerShell/.NET-layer effect, pinned by the read-only suite — the device DACL is not the denying party); PowerShell's `> $null` redirection keeps working (it discards without opening NUL).
+- **Everyone grants remain ambient write authority** — Everyone must stay in both restricting lists (removing it breaks early DLL initialization and CNG); an external NTFS object whose DACL grants Everyone a requested write right clears both checks and stays writable under both modes.
+- **Hard links are file-object aliases, not path aliases** — an inheritable workspace ACE propagated onto an existing hard link changes the one underlying file security descriptor, so the same object is writable through an external alias; rejecting multiply-linked files is not viable for ordinary pnpm installations.
+- **Writes are restricted; reads, network, and process visibility are not** — `WRITE_RESTRICTED` intersects write accesses only, so a confined child can read any caller-readable file and open sockets; `read-only` therefore needs a read-side policy to be expressed.
+- **Console isolation is unavailable** — children created with `CREATE_NO_WINDOW` / `CREATE_NEW_CONSOLE` die during DLL initialization with `STATUS_DLL_INIT_FAILED` (`0xC0000142`); children share the host console, and pipe-based stdio redirection is unaffected.
+- **ACL grants are standing directory mutations** — workspace ACEs stand by design (the reuse cache, never revoked); temp ACEs are revoked by `dispose()`; manual `icacls` cleanup cannot revoke them on this platform (`ERROR_NONE_MAPPED`, 1332), so revoke through this module.
+- **Granted directories must be caller-owned** — the owner's implicit `WRITE_DAC` is what lets the sandbox edit the DACL without elevation.
+- **The ambient temp root is never granted implicitly** — direct callers must supply an existing private `tempDir` plus its distinct `tempWriteSid`, or disable temp writes with `tempDir: null`; the actual temp directory must be disjoint from every writable root.
+- **The confined child's temp capability is private per live session/workspace pair** — the runner rewrites TMP/TEMP to that private directory before the spawn; two tokens sharing the same workspace SID cannot write one another's temp directories.
+- **`whoami` and token-inspection cmdlets fail under the restricted token** — `GetTokenInformation` on the duplicate is partially unavailable to the child, which is diagnostic noise rather than an operational failure.
 
-Authenticated Users is absent from BOTH lists — the WMI namespace security check fails (`0x80041003`), so CIM cmdlets and `Get-ComputerInfo` (which silently returns incomplete results rather than an error) are unavailable in EVERY confined mode, and the C:\-root tree-creation escape (standing `AU:(AD)` + `AU:(OI)(CI)(IO)(M)` ACEs) is closed in both — the model-facing documentation states that contract, not a prompt promise. INTERACTIVE/LOCAL are absent from BOTH lists too: the host's Public tree grants write to INTERACTIVE, so Public writes are denied — pinned by the runner's ambient-writable Public-probe regression (see the design note).
+### Header verification and source map
 
-The `AclSandbox` class (explicit private `tempDir` + `tempWriteSid`, or `tempDir: null` to disable temp writes) remains the programmatic API for direct spawns; `AclWriteGrant` is the server-side materialization half of the grant lifecycle.
+The sandbox-owned SID, ACL, token, file, and lock declarations are checked against Windows headers by [`verify/abi-probe.cpp`](verify/abi-probe.cpp). The shared process, stdio, and Job ABI is owned and verified by [`@deepseek-ai/dsh-win32-process`](../../subprocess/win32-process/README.md#header-verification).

-## Verified boundaries (inherent to restricted tokens, not this port)
+<a id="further-exploration"></a>
+## Further Exploration
 
-- **Everyone grants remain ambient write authority.** Everyone must stay in both restricting lists: removing it breaks early DLL initialization and CNG. An external NTFS object whose normal DACL grants Everyone a requested write right therefore clears both access checks and stays writable under both modes. The real runner suite provisions an external `Everyone:Modify` directory and pins that behavior; the provider reports `enforcement: 'partial'` so callers can reject or surface the weaker boundary.
-- **Hard links are file-object aliases, not path aliases.** An inheritable workspace ACE propagated onto an existing NTFS hard link changes the one underlying file security descriptor, so the same object is writable through an external alias. Rejecting every multiply-linked workspace file is not viable for ordinary pnpm installations, which use hard links into their content-addressable store; the native runner suite pins the gap and the provider's partial report names its consequence.
-- **Writes are restricted; reads, network, and process visibility are not.** `WRITE_RESTRICTED` intersects write accesses only, so a confined child can read any caller-readable file and open sockets. `read-only` mode therefore cannot be expressed by this mechanism alone; pair it with a read-side policy or an AppContainer/`S-1-15-2` capability token for stronger confinement.
-- **Console isolation is unavailable.** Under the restricted token, children created with `CREATE_NO_WINDOW` / `CREATE_NEW_CONSOLE` die during DLL initialization with `STATUS_DLL_INIT_FAILED` (`0xC0000142`). The POC tried to fix this by adding the console logon SID (`S-1-2-1`) to the restricting list; on Windows 11 26200 `CreateWellKnownSid(WinLocalLogonSid)` fails with `ERROR_INVALID_PARAMETER` (87), the correct `WinConsoleLogonSid` yields a valid `S-1-2-1` but the child still dies, and the POC's final revision removed both the SID and console isolation. Children therefore share the host console; stdio redirection is pipe-based and unaffected.
-- **ACL grants are standing directory mutations.** They persist if the process dies mid-run; workspace ACEs are standing BY DESIGN (never revoked — the reuse cache), temp ACEs are revoked by `dispose()` (`init()` also revokes an already-applied temp grant when a later step fails). The POC's documented manual cleanup (`icacls <dir> /remove '*S-1-4-…'`) fails on this platform with `ERROR_NONE_MAPPED` (1332) — revoke through this module instead. An unclean shutdown needs no self-healing for the workspace ACE: the derived SID re-hits the standing ACE on the next provision (skipping the apply); the write-SID ACE never accumulates a second identity per restart because the identity IS the workspace.
-- **Granted directories must be caller-owned.** The owner's implicit `WRITE_DAC` is what lets the sandbox edit the DACL without elevation.
-- **The ambient temp root is never granted implicitly.** A direct `AclSandbox` workspace-write caller must supply an existing private `tempDir` plus its distinct `tempWriteSid`, or explicitly disable temp writes with `tempDir: null`. The actual temp directory must be disjoint from every writable root. The seam creates a random private directory; agentless runner calls treat `--temp` as the parent root and create their own random child, but reject a workspace equal to or containing that parent before any ACL mutation.
-- **The confined child's temp capability is private per live session/workspace pair.** The runner rewrites TMP/TEMP via `SetEnvironmentVariableW` to that private directory before the spawn and the child inherits the rewritten block (bwrap `--tmpfs /tmp` semantics). The temp ACE and directory are removed on provider disposal, or after each agentless invocation. A crash can leave inert `%TEMP%` litter, but a resumed provider chooses a new random path and SID instead of colliding with or reauthorizing the residue. The native runner suite proves that two tokens sharing the same workspace SID cannot write one another's temp directories.
-- **`whoami` and token-inspection cmdlets fail under the restricted token.** `GetTokenInformation` on the duplicate is partially unavailable to the child, so `whoami /all` reports errors — diagnostic noise of the restriction scheme, not an operational failure; the denial surfaces that matter (file writes) are unaffected.

 ## Known Limitations and Deferred Work
 
-- **One write allowlist per workspace** — the write SID is the unit of the allowlist and IS the workspace identity; reusing one sandbox instance across two workspaces widens both grants to both roots (the same SID would then name two roots). Create one instance per workspace root — the seam does exactly this, keyed by the workspace path.
-- **Cleanup is best-effort by design** — `dispose()` attempts every temp revocation and aggregates failures into an `AggregateError`; a cleanup failure can leave the random directory and its temp-SID-only ACE behind. Once the process exits no future token carries that SID, so the residue is inert until OS temp hygiene or manual directory removal reclaims it.
-- **Standing workspace ACEs are invisible residue.** Renaming a workspace derives a new SID; the old ACEs on the old path stay (inert, write-SID-only). A future cleanup command may reap them; nothing re-propagates because of them.
-- **Piped stdio capture is impossible for confined grandchildren (the named-pipe default SD template).** libuv's pipe stdio uses NAMED pipes; `CreateNamedPipeW` without security attributes installs the Win32 layer's user-mode default SD template (built by KernelBase — owner/SYSTEM/Admins full, Everyone/ANONYMOUS read-only, the fixed template [MS documents](https://learn.microsoft.com/en-us/windows/win32/ipc/named-pipe-security-and-access-rights)) — NOT the token default DACL, which is what the kernel applies to a raw SD-null create — so the client-end open requests write access no restricting SID is granted: `spawn(..., { stdio: 'pipe' })` inside a confined process fails with EPERM, the POC-documented "no output redirection" boundary of WRITE_RESTRICTED tokens. Inherited (`inherit`/fd) and ignored (`ignore`) stdio spawns work, and anonymous pipes (CreatePipe — a token-default-DACL consumer, e.g. PowerShell pipelines) work because the restricted token's default DACL carries a full-access restricting-SID ACE (set at init). A confined process therefore cannot capture a grandchild's output through a pipe; tools that must capture output cannot run confined.
-- **Grant materialization is an eager full-tree propagation.** `SetNamedSecurityInfoW` on a directory with inheritable ACEs walks every descendant immediately (NOT lazily per access — measured at tens of seconds on large workspace trees). The per-workspace identity pays it once per workspace per machine (lazily at the first confined execution ever, skipped entirely on every later provision when the exact ACE stands). Private temp directories start empty, so their distinct grant is cheap. If a workspace is huge, the first confined write on this host is correspondingly slow.
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define when the backend is a poor fit or needs special operational care. They are current package constraints, not a general Windows comparison or a task backlog.
+
+- **One write allowlist per workspace** — the write SID is the unit of the allowlist and IS the workspace identity; reusing one sandbox instance across two workspaces widens both grants to both roots. Create one instance per workspace root — the seam does exactly this, keyed by the workspace path.

Once the process exits no future token carries that SID, so the residue is inert until OS temp hygiene or manual removal reclaims it.
+- **Standing workspace ACEs are invisible residue** — renaming a workspace derives a new SID; the old ACEs on the old path stay (inert, write-SID-only), and a future cleanup command may reap them.
+- **NULL-DACL directories are not identity-preserving under grant+revoke** — a directory with a NULL DACL means "everyone full control"; `grantWrite` builds the new ACL from that null, and the revoke round-trip leaves an empty (deny-all) DACL rather than the original NULL DACL. Real workspace and temp directories carry real DACLs, so this stays a documented edge.
+- **Piped stdio capture is impossible for confined grandchildren** — libuv's pipe stdio uses named pipes, whose client-end open requests write access no restricting SID is granted (the Win32 layer's default SD template, not the token default DACL), so `spawn(..., { stdio: 'pipe' })` inside a confined process fails with EPERM; inherited and ignored stdio spawns work, and anonymous pipes (PowerShell pipelines) work because the restricted token's default DACL carries a full-access restricting-SID ACE.
+- **Grant materialization is an eager full-tree propagation** — `SetNamedSecurityInfoW` on a directory with inheritable ACEs walks every descendant immediately (tens of seconds on large workspace trees); the per-workspace identity pays it once per workspace per machine, and the exact-ACE skip makes every later provision cheap.
 - **Read-side confinement and network policy are out of scope** — `WRITE_RESTRICTED` intersects write accesses only; pair this backend with a read-side policy for stronger confinement.
-- **Wide-directory and FAT-volume warnings are deferred; FAT-class targets stay writable.** The UI-side warnings for granting unusually wide directories or FAT-class (non-ACL) volumes are not yet implemented, and a FAT volume as a grant ROOT simply fails the grant loudly (no ACL support). A FAT-class target OUTSIDE the granted roots is different: it has no security descriptors, so the restricted token's write check passes (Everyone sits in both lists) and such targets are writable under BOTH confined modes. FAT is treated as a legacy residue — unsupported and not engineered around; this warn-only posture is documented here rather than mitigated.
-- **PowerShell language mode differs by confined mode.** Under `read-only`, PowerShell cannot create its AppLocker probe files in temp and conservatively starts in ConstrainedLanguage: `Add-Type` (C# compile, P/Invoke), non-core .NET static calls (`[System.IO.*]::`, `[math]::`, `[Environment]::`), COM objects, and reflection fail with `Cannot create type` / `Cannot invoke method` ("only core types") errors, and `$ExecutionContext.SessionState.LanguageMode = 'FullLanguage'` is refused. Under the shipped `workspace-write` path, the private-temp capability lets that probe complete, so pwsh stays in FullLanguage unless host-wide WDAC/AppLocker policy says otherwise; a direct `AclSandbox` configured with `tempDir: null` has no such guarantee and can fail the probe closed like read-only. This split is PowerShell startup behavior, not part of the ACL write boundary. The `pwsh` tool description teaches the shipped modes to the model; `danger-full-access` calls run unconfined at FullLanguage.
+- **Wide-directory and FAT-volume warnings are deferred; FAT-class targets stay writable** — the UI-side warnings are not implemented, a FAT volume as a grant root fails loudly, and a FAT-class target outside the granted roots has no security descriptors so it stays writable under both confined modes; FAT is treated as legacy residue.

-面向 [harness 沙盒 seam](../sandbox/) 的 Windows 写入限制沙盒后端：一个 Node.js/[koffi](https://koffi.dev/) 实现的、对 [huoyaoyuan/windows-acl-restrict-poc](https://github.com/huoyaoyuan/windows-acl-restrict-poc)（`10e4dfb`，固定修订版本）机制的移植，挂载为 [`@deepseek-ai/dsh-sandbox-local`](../sandbox-local/) 链中报告 `enforcement: 'partial'` 的 win32 一级（`workspace-write` / `read-only` 两种模式）；Linux/macOS 后端在同一包中。
+## 概述
 
-一句话机制：把调用者令牌复制为 `WRITE_RESTRICTED` 受限令牌，其 restricting SIDs 携带彼此独立的工作区能力与私有临时目录能力。工作区 SID 由规范工作区路径确定性派生（`workspaceWriteSid`），因此工作区根目录 ACE 每台机器每个工作区只物化一次，之后每次会话、调用或重启都命中精确 ACE 跳过。每个活跃的会话/工作区对则获得一个随机临时目录，以及一个从该路径派生的 SID（`tempWriteSid`），因此各会话共享预期的工作区权限，却不会继承彼此的临时目录权限。此后 Windows 只在「调用者正常权限」与「restricting SID 交集」同时允许时才放行写入。这些 SID 是主要白名单，在系统其余位置不授予任何权限；但该检查还会继承**其他** restricting SID 的环境写 ACE（保活组登录 SID + Everyone），而 NTFS ACL 属于文件对象而非路径。Everyone 与硬链接边界正是该档报告部分而非完整强制执行的原因。
+`dsh-sandbox-windows-acl` 通过写入限制隔离 Windows 进程：子进程在受限令牌下运行，其写访问仅限于工作区与私有临时目录，因此 `workspace-write` 允许这些写入，`read-only` 则不允许任何写入。它作为 `dsh-sandbox-local` 的 win32 档交付：在 Windows 上挂载本地提供方，就能让每次受限 bash 或 pwsh 调用自动使用此后端。也可以通过 `AclSandbox` API 直接嵌入，以捕获 stdio 的方式 spawn 受限子进程。每个 Win32 调用都有检查，失败即抛出异常，因此子进程绝不会不受限制地 spawn。强制执行按设计为部分实现——受限令牌必须为进程初始化保留 Everyone，且 NTFS 硬链接可以把同一文件对象别名为多个路径——因此后端报告 `partial`，需要绝对边界的调用方可以向上暴露它。
 
-直接构建在原生 ACL 机制上是记录在案的设计选择：它实现两种隔离模式，且不背负被否决的容器方案的问题——见[设计笔记](../../../.agents/notes/implemented/feature/2026-08-08-windows-acl-restricted-token-sandbox.zh.md)（[mxc](https://github.com/microsoft/mxc/blob/main/docs/process-container/os-version-support.md) 要求 Windows 11 24H2 的 OS 下限，且任意路径读取需要整体改写宿主 DACL；AppContainer 根本无法任意路径读取）。

+## 使用本包
+
+在 Windows 上，挂载本地沙箱提供方后，此后端就是 `ctx.sandbox` 背后的 runner——无需额外配置。要在 harness 之外 spawn 受限子进程时，直接嵌入 `AclSandbox` API。
+
+### 何时选择
+
+为在 `read-only` 或 `workspace-write` 下隔离子进程文件操作的 Windows 组合选择它。当子进程还需要读侧隔离或网络限制时请另选机制：`WRITE_RESTRICTED` 只交叉检查写访问，因此请把此后端与读侧策略或 AppContainer 能力令牌配对以获得更强隔离。
+
+### 直接 API
+
+`AclSandbox` 以捕获 stdio 的方式 spawn 受限子进程（runner 风格使用可用继承 stdio）。它要求显式提供私有临时目录，或用 `tempDir: null` 禁用临时写入——环境临时根目录绝不会被隐式授权。
 
 ```ts
 import { mkdtempSync, rmSync } from 'node:fs'
@@ -38,65 +63,127 @@ sandbox.dispose() // revokes the revocable (temp) grant, keeps the standing work
 rmSync(tempDir, { recursive: true, force: true })
 ```
 
-直接使用 `AclSandbox` 时，必须显式提供私有临时目录（或通过 `tempDir: null` 禁用临时写入；环境临时根目录绝不会被隐式授权），工作区 ACE 以**常驻**方式授予（`dispose()` 保留它们——它们是跨实例的复用缓存），不同的临时 SID 则以**可回收**方式授予。服务端复用则是 `AclWriteGrant` 类：每个目录一次 `add(path, standing)`，`dispose()` 撤销可回收路径并释放 SID——见下方 runner 契约。每个 policy-specific Win32 调用和 [`dsh-win32-process`](../../subprocess/win32-process/README.zh.md) 提供的 process primitive 都有检查；失败抛出 `Win32Error`，携带 API 名、精确 Win32 错误码、`FormatMessageW` 系统文本和失败的路径/上下文。这是刻意的：POC 忽略每个返回值，当 `CreateRestrictedToken` 失败时用完整无限制令牌静默运行子进程（fail-open）。本移植从构造上 fail-closed。

+### 隔离给你带来什么
 
-## 隔离 runner
+在 `workspace-write` 下，子进程可以写入工作区及其私有临时目录；受 ACL 管辖的其他写入都会被拒绝，已记录的 Everyone 与硬链接边界除外。在 `read-only` 下不存在显式写入授权，因此写入会被拒绝，同样带有已记录的边界。
 
-面向 seam 的形态是 **runner 入口**（`./runner`）：`@deepseek-ai/dsh-sandbox-local` 在调用者命令的位置 spawn 的 argv 前缀包装——与 bwrap/landlock-run/sandbox-exec 同一架构，因此沙盒 seam 的 `confine()` 契约无需改动。稳定的 argv 契约：
+临时隔离按每个活跃的会话/工作区对进行：共享工作区的会话共享其写权限，但无法写入彼此的临时目录。新的提供方总会选择新的临时路径和 SID，因此崩溃残留既无法阻止恢复的会话，也无法向其授权。

+
+`init()` 在任何 Win32 失败时抛出——子进程绝不会不受限制地 spawn。执行命令前失败的 runner 会向 stderr 打印 `windows-acl-run: <detail>` 并以 127 退出，seam 的 runner 失败规则将其归类为损坏的沙箱，而非拒绝。清理按设计尽力而为：`dispose()` 会尝试全部临时撤销并把失败聚合为 `AggregateError`。

+## 理解实现
+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释受限令牌机制、令牌列表、runner 约定与已验证边界；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 机制
+
+调用者令牌被复制为 `WRITE_RESTRICTED` 受限令牌，其 restricting SIDs 携带彼此独立的工作区与私有临时目录能力。Windows 执行两次访问检查——先对正常 SID，再对 restricting SID——并且只在两次检查都通过时才授予写类访问。工作区 SID 由规范工作区路径确定性派生（`workspaceWriteSid`），因此工作区根目录 ACE 每台机器每个工作区只物化一次，之后每次会话、调用或重启都命中精确 ACE 跳过。每个活跃的会话/工作区对则获得一个随机私有临时目录，以及一个从该路径派生的 SID（`tempWriteSid`），因此各会话共享预期的工作区权限，却不会继承彼此的临时目录权限。每个策略专用 Win32 调用和 [`dsh-win32-process`](../../subprocess/win32-process/README.zh.md) 提供的进程原语都有检查；失败抛出携带 API 名、精确错误码、系统文本与失败上下文的 `Win32Error`——从构造上 fail-closed。
+
+### 模式与令牌列表
+
+`workspace-write`（登录 SID、Everyone、工作区 SID、临时 SID）为工作区与会话的私有临时子目录分别授予 Write；`read-only`（登录 SID、Everyone——不含写入 SID）不授予任何内容。保活组（登录 SID + Everyone）在两种模式下都存在：没有它，早期 DLL 初始化会以 `0xC0000142` 死亡、CNG 会让 pwsh 以 `0xE0434352` 崩溃。写入 SID 有意留在 read-only 列表之外：先前 workspace-write 时期留下的常驻授权 ACE 仍然失效，因为 write-restricted 的 pass-2 检查只授予 restricting 列表所携带的内容，而常驻 ACE 让重新升级免于重新传播。
+
+NUL 写入是环境性的、不是被授权的：设备 DACL 授予 Everyone 读+写+执行（`0x1201BF`），因此访问掩码落在其内的打开者（cmd 的 `> NUL`、node 的 `\\.\NUL`）在两种模式下都能写。`Set-Content NUL` 在两种模式下都失败（PowerShell/.NET 层效应，非设备 DACL 所致），而 PowerShell 的 `> $null` 重定向不受影响。
+
+Authenticated Users 在两种列表中都不存在——WMI 命名空间安全检查失败（`0x80041003`），因此 CIM cmdlet 与 `Get-ComputerInfo` 在所有受限模式下都不可用，且 C:\-root 树创建逃逸被关闭。INTERACTIVE/LOCAL 同样不存在：宿主的 Public 树向 INTERACTIVE 授予写权限，因此 Public 写入被拒绝。
+
+### 隔离 runner
+
+面向 seam 的形态是 runner 入口（`./runner`）：`dsh-sandbox-local` 在调用者命令的位置 spawn 的 argv 前缀包装——与 bwrap/landlock-run/sandbox-exec 同一架构。runner 创建受限令牌，在它之下 spawn 包装后的 argv，调用者的 stdio 直接透传，把子进程包进 `KILL_ON_JOB_CLOSE` job，镜像子进程的退出码，并在退出时撤销其自行管理的临时授权。每个 runner 侧失败都会向 stderr 打印 `windows-acl-run: <detail>` 并以 127 退出——seam 的 runner 失败规则匹配该签名。
 
 ```sh
 node runner.js --workspace <dir> --temp <dir> --mode <read-only|workspace-write> [--write-sid <S-1-4-…> --temp-write-sid <S-1-4-…>] -- <argv...>
 ```
 
-runner 创建受限令牌，在它之下 spawn 包装后的 argv，调用者的 stdio 直接透传（调用者的管道在 spawn 前后被设为可继承——Node 在启动时清除 stdio 可继承性，裸 spawn 必须补偿这一点），把子进程包进 `KILL_ON_JOB_CLOSE` job（runner 死亡则子进程死亡），忽略自身的控制台 Ctrl+C 让子进程自行处理，镜像子进程的退出码，并在退出时撤销其自行管理的临时授权（工作区 ACE 常驻）。每个 runner 侧失败都会向 stderr 打印 `windows-acl-run: <detail>` 并以 127 退出——seam 的 `RUNNER_FAILURE_RULES` 匹配该签名，因此 runner 拒绝永远不会被误判为拒绝授权。
+seam 先把确定性工作区 SID 的 ACE 常驻物化（每个工作区每服务器生命周期一次——复用缓存），再为每个活跃的会话/工作区对创建随机私有临时目录和不同的可回收 SID，把两种身份作为必须成对出现的 `--write-sid`/`--temp-write-sid` 传入；runner 对照各自所属路径验证二者，既不授权也不撤销（`manageDacls: false`）。fork 获得不同的临时能力；即使恢复的是同一会话，新的提供方也会给出新的路径和 SID，因此崩溃残留只是失效垃圾。如果不带这一对标志，`--temp` 指定的是根目录：无 agent（智能体）/独立的 workspace-write runner 会创建随机私有子目录，自行管理其临时 SID，重写 TMP/TEMP，并在退出时移除该子目录。重启后重新授权常驻工作区 ACE 是幂等的：`grantWrite` 读取当前 DACL，当完全相同的 ACE 已存在时跳过重新传播。工作区若等于或包含临时根目录，会在任何授权前被拒绝。
 
-**工作区复用与临时隔离**：seam 先把确定性工作区 SID 的 ACE **常驻**物化（每个工作区每服务器生命周期一次，绝不撤销——它就是复用缓存），再为每个活跃的会话/工作区对创建随机私有临时目录和不同的可回收 SID。它把两种身份作为必须成对出现的 `--write-sid`/`--temp-write-sid` 传入；runner 对照各自所属路径验证二者，既不授权也不撤销（`manageDacls: false`）。fork 获得不同的临时能力；即使恢复的是同一会话，新的提供方也会给出新的路径和 SID，因此崩溃残留只是失效垃圾，而非冲突或继承的能力。如果不带这一对标志，`--temp` 指定的是根目录：无 agent（智能体）/独立的 workspace-write runner 会创建随机私有子目录，自行管理其临时 SID，重写 TMP/TEMP，并在退出时移除该子目录。工作区若等于或包含该根目录，会在任何授权前被拒绝，因为否则其可继承的工作区 ACE 会向每个私有子目录授权；直接 API 同样拒绝任何可写根目录与实际私有临时目录重叠。重启后重新授权常驻工作区 ACE 是幂等的：`grantWrite` 读取当前 DACL，当完全相同的 ACE 已存在时跳过 `SetNamedSecurityInfoW`（应用该 ACE 会把相同的 ACE 急切地重新传播到整棵树——大型工作区上以分钟计）。已知代价：大型工作区树的首次授权会阻塞整次急切传播，每台机器每个工作区一次。
+### 已验证边界
 
-模式（令牌的 restricting-SID 列表随模式而变；保活组登录 SID + Everyone 在**两种**模式下都存在——没有它们早期 DLL 初始化会以 `0xC0000142` 死亡、CNG 会让 pwsh 以 `0xE0434352` 崩溃）：
-- `workspace-write`（登录 SID、Everyone、工作区 SID、临时 SID）：工作区与会话的**私有**临时子目录分别携带 Write 授权；受 ACL 管辖的其他写入都会被拒绝，已记录的 Everyone 与硬链接边界除外。
-- `read-only`（登录 SID、Everyone——**不含**写入 SID）：不存在显式的写入 SID 授权。写入 SID 有意留在列表**之外**：先前 workspace-write 时期留下的常驻授权 ACE（`/permission` 降级，或崩溃后恢复的会话）在 read-only 下保持**失效**，因为 write-restricted 的 pass-2 检查只授予 restricting 列表所携带的内容——而常驻 ACE 让重新升级免于重新传播。Everyone 的环境权限仍构成已记录的部分强制执行边界。NUL 写入是**环境性**的、不是被授权的：设备 DACL 授予 Everyone 读+写+执行（`0x1201BF`），因此访问掩码落在其内的打开者（cmd 的 `> NUL`、node 的 `\\.\NUL`）在**两种**模式下都能写——只要 Everyone 还在保活组里，沙盒就无法把 NUL 设备归零。`Set-Content NUL` 在两种模式下都失败（PowerShell/.NET 层效应，由 read-only 套件钉住——拒绝方不是设备 DACL）；PowerShell 的 `> $null` 重定向不受影响（它直接丢弃、不打开 NUL）。
+- **Everyone 授权仍是环境中的写权限来源。** Everyone 必须保留在两种 restricting 列表中（移除它会破坏早期 DLL 初始化与 CNG）；外部 NTFS 对象若其 DACL 向 Everyone 授予所请求的写权限，就会同时通过两次检查，并在两种模式下保持可写。
+- **硬链接是文件对象别名，而非路径别名。** 传播到已有硬链接上的可继承工作区 ACE 会修改底层同一文件的安全描述符，因此同一对象也可通过外部别名写入；拒绝工作区中的所有多链接文件不具可行性，因为普通 pnpm 安装会使用硬链接。
+- **写入受限；读取、网络与进程可见性不受限。** `WRITE_RESTRICTED` 只交叉检查写访问，因此受限子进程可以读取调用者可读的任何文件并打开套接字；`read-only` 因而需要读侧策略才能表达。
+- **控制台隔离不可用。** 以 `CREATE_NO_WINDOW` / `CREATE_NEW_CONSOLE` 创建的子进程在 DLL 初始化期间以 `STATUS_DLL_INIT_FAILED`（`0xC0000142`）死亡；子进程共享宿主控制台，基于管道的 stdio 重定向不受影响。
+- **ACL 授权是对真实目录的驻留改动。** 工作区 ACE 按设计常驻（复用缓存，绝不撤销）；临时 ACE 由 `dispose()` 撤销；手工 `icacls` 清理无法在本平台回收它们（`ERROR_NONE_MAPPED` 1332），请通过本模块回收。
+- **被授权目录必须由调用者拥有。** 所有者的隐式 `WRITE_DAC` 是沙箱无需提权即可编辑 DACL 的原因。
+- **环境临时根目录绝不会被隐式授权。** 直接调用方必须提供已存在的私有 `tempDir` 及其不同的 `tempWriteSid`，或用 `tempDir: null` 禁用临时写入；实际临时目录不得与任何可写根目录重叠。
+- **受限子进程的临时能力按每个活跃的会话/工作区对私有。** runner 在 spawn 之前把 TMP/TEMP 改写为该私有目录；共享同一工作区 SID 的两个令牌无法写入彼此的临时目录。
+- **受限令牌下 `whoami` 与令牌检查 cmdlet 会失败。** 子进程对复制令牌的 `GetTokenInformation` 部分不可用，这是诊断噪音而非运行故障。
 
-Authenticated Users 在**两种**列表中都不存在——WMI 命名空间安全检查失败（`0x80041003`），因此 CIM cmdlet 与 `Get-ComputerInfo`（它静默返回不完整结果而非报错）在**所有**受限模式下都不可用，且 C:\-root 树创建逃逸（常驻的 `AU:(AD)` + `AU:(OI)(CI)(IO)(M)` ACE）在两种模式下都被关闭——面向模型的表面记录的是该契约，而不是提示词承诺。INTERACTIVE/LOCAL 在两种列表中同样不存在：宿主的 Public 树向 INTERACTIVE 授予写权限，因此 Public 写入被拒绝——由 runner 的环境可写 Public 探针回归测试钉住（见设计笔记）。
+### 头部验证与源码地图

+## 进一步探索
 
-- **Everyone 授权仍是环境中的写权限来源。** Everyone 必须保留在两种 restricting 列表中：移除它会破坏早期 DLL 初始化与 CNG。因此，如果外部 NTFS 对象的正常 DACL 向 Everyone 授予所请求的写权限，它就会同时通过两次访问检查，并在两种模式下保持可写。真实 runner 套件配置一个外部 `Everyone:Modify` 目录并钉住该行为；提供方报告 `enforcement: 'partial'`，使调用方能够拒绝或向上暴露这项较弱的边界。
-- **硬链接是文件对象别名，而非路径别名。** 传播到已有 NTFS 硬链接上的可继承工作区 ACE 会修改底层同一文件的安全描述符，因此同一对象也可通过外部别名写入。拒绝工作区中的所有多链接文件不具可行性，因为普通 pnpm 安装会使用硬链接指向其内容寻址存储；原生 runner 套件钉住该缺口，提供方的部分强制执行报告则点明其后果。
-- **写入受限；读取、网络与进程可见性不受限。** `WRITE_RESTRICTED` 只交叉检查写访问，因此受限子进程可以读取调用者可读的任何文件并打开套接字。`read-only` 模式因而不能仅靠该机制表达；将其与读侧策略或 AppContainer/`S-1-15-2` capability 令牌配对以获得更强隔离。
-- **控制台隔离不可用。** 在受限令牌下，以 `CREATE_NO_WINDOW` / `CREATE_NEW_CONSOLE` 创建的子进程在 DLL 初始化期间以 `STATUS_DLL_INIT_FAILED`（`0xC0000142`）死亡。POC 尝试把控制台登录 SID（`S-1-2-1`）加入 restricting 列表来修复；在 Windows 11 26200 上 `CreateWellKnownSid(WinLocalLogonSid)` 以 `ERROR_INVALID_PARAMETER`（87）失败，正确的 `WinConsoleLogonSid` 能产出合法 `S-1-2-1` 但子进程仍然死亡，POC 的最终修订同时移除了该 SID 与控制台隔离。子进程因此共享宿主控制台；stdio 重定向走管道，不受影响。
-- **ACL 授权是对真实目录的驻留改动。** 进程中途死亡会留下授权；工作区 ACE **按设计**常驻（绝不撤销——复用缓存），临时 ACE 由 `dispose()` 撤销（后续步骤失败时 `init()` 也会撤销已应用的临时授权）。POC 注释里的手工清理命令（`icacls <dir> /remove '*S-1-4-…'`）在本平台实测失败（`ERROR_NONE_MAPPED` 1332）——请通过本模块回收。工作区 ACE 在异常关闭后无需自愈：派生 SID 在下一次供给时重新命中常驻 ACE（跳过应用）；写入 SID ACE 不会因每次重启而累积第二个身份，因为身份**就是**工作区。
-- **被授权目录必须由调用者拥有。** 所有者的隐式 `WRITE_DAC` 是沙盒无需提权即可编辑 DACL 的原因。
-- **环境临时根目录绝不会被隐式授权。** 直接使用 `AclSandbox` 的 workspace-write 调用方必须提供一个已存在的私有 `tempDir` 及其不同的 `tempWriteSid`，或通过 `tempDir: null` 显式禁用临时写入。实际临时目录不得与任何可写根目录重叠。seam 会创建随机私有目录；无 agent runner 调用把 `--temp` 视为父根目录并自行创建随机子目录，但如果工作区等于或包含该父根目录，就会在任何 ACL 改动前拒绝调用。
-- **受限子进程的临时能力按每个活跃的会话/工作区对私有。** runner 在 spawn 之前用 `SetEnvironmentVariableW` 把 TMP/TEMP 改写为该私有目录，子进程继承改写后的环境块（bwrap `--tmpfs /tmp` 的语义）。临时 ACE 与目录会在提供方 dispose 时移除，或在每次无 agent 调用后移除。崩溃可能留下失效的 `%TEMP%` 垃圾，但恢复后的提供方会选择新的随机路径和 SID，而不会与残留发生冲突或重新向其授权。原生 runner 套件证明，共享同一工作区 SID 的两个令牌无法写入彼此的临时目录。
-- **受限令牌下 `whoami` 与令牌检查 cmdlet 会失败。** 子进程对复制令牌的 `GetTokenInformation` 部分不可用，因此 `whoami /all` 报错——这是限制方案的诊断噪音，不是运行故障；真正重要的拒绝面（文件写入）不受影响。

-## 已知限制与暂缓事项
+## 已知限制与延期工作
 
-- **每个工作区一个写入白名单** —— 写入 SID 是白名单的基本单位，且**就是**工作区身份；同一沙盒实例跨两个工作区复用时，两个根目录会互相扩大授权面（同一个 SID 将命名两个根）。请按工作区根目录各建一个实例——seam 正是这样做的，以工作区路径为键。
-- **清理按设计尽力而为** —— `dispose()` 会尝试全部临时撤销并把失败聚合为 `AggregateError`；清理失败可能留下随机目录及其仅含临时 SID 的 ACE。进程退出后，不会再有令牌携带该 SID，因此残留保持失效，直到 OS 临时目录卫生或手动移除目录将其回收。
-- **常驻工作区 ACE 是不可见残留。** 工作区改名会派生新的 SID；旧路径上的旧 ACE 留在原地（失效、仅含写入 SID）。未来的清理命令可以回收它们；它们不会引起任何重新传播。
-- **受限孙进程的管道 stdio 捕获不可用（named pipe 的默认 SD 模板）。** libuv 的管道 stdio 用的是 NAMED pipe；不带安全属性调用 `CreateNamedPipeW` 时，其默认安全描述符不是内核的模板，而是 Win32 层在用户态安装的默认 SD 模板（由 KernelBase 构建——owner/SYSTEM/Admins 全权，Everyone/ANONYMOUS 只读，即 [MS 文档](https://learn.microsoft.com/en-us/windows/win32/ipc/named-pipe-security-and-access-rights)记载的固定模板）——**不是**令牌默认 DACL（后者才是内核在原始 SD-null 创建时应用的）——因此 client 端打开所请求的写访问没有任何 restricting SID 被授予：受限进程内 `spawn(..., { stdio: 'pipe' })` 以 EPERM 失败，这是 POC 记载的 WRITE_RESTRICTED「无法重定向输出」边界。继承（`inherit`/fd）与忽略（`ignore`）stdio 的 spawn 可用；匿名管道（CreatePipe——令牌默认 DACL 的消费者，例如 PowerShell 的管道）因受限令牌默认 DACL 携带 restricting SID 全权 ACE（init 时写入）而可用。受限进程因此无法用管道捕获孙进程输出；必须捕获输出的工具无法在受限下运行。
-- **授权物化是急切的全树传播。** 在带可继承 ACE 的目录上调用 `SetNamedSecurityInfoW` 会立即遍历每个后代（**不是**按访问惰性进行——大型工作区树上实测数十秒）。按工作区身份每台机器每个工作区只付一次（在首次受限执行时惰性进行，之后每次供给在精确 ACE 常驻时完全跳过）。私有临时目录创建时为空，因此其独立授权开销很小。如果工作区巨大，该主机上的第一次受限写入相应变慢。
-- **读侧隔离与网络策略不在范围内** —— `WRITE_RESTRICTED` 只交叉检查写访问；将此后端与读侧策略配对以获得更强隔离。
-- **宽目录与 FAT 卷警告已推迟；FAT 类目标保持可写。** 对异常宽的目录或 FAT 类（非 ACL）卷的 UI 侧警告尚未实现，且 FAT 卷作为授权**根**只会大声失败（无 ACL 支持）。授权根**之外**的 FAT 类目标则不同：它没有安全描述符，因此受限令牌的写检查通过（Everyone 在两种列表中都在）——此类目标在**两种**受限模式下都可写。FAT 被视为遗留残留——不受支持、不围绕它设计；此处记录的是这种仅警告的立场，而非缓解措施。
-- **PowerShell 语言模式因受限模式而异。** 在 `read-only` 下，PowerShell 无法在临时目录中创建 AppLocker 探针文件，因此会保守地以 ConstrainedLanguage 启动：`Add-Type`（C# 编译、P/Invoke）、非核心 .NET 静态调用（`[System.IO.*]::`、`[math]::`、`[Environment]::`）、COM 对象与反射以 `Cannot create type` / `Cannot invoke method`（「only core types」）错误失败，且 `$ExecutionContext.SessionState.LanguageMode = 'FullLanguage'` 被拒绝。交付的 `workspace-write` 路径拥有私有临时目录能力，可使该探针完成，因此除非主机范围的 WDAC/AppLocker 策略另有规定，否则 pwsh 保持 FullLanguage；直接使用 `AclSandbox` 并配置 `tempDir: null` 时则没有这一保证，探针可能像 read-only 一样失败并按 fail-closed 处理。这一区别属于 PowerShell 启动行为，不是 ACL 写入边界的一部分。`pwsh` 工具描述向模型传授这些交付模式；`danger-full-access` 调用不受限地在 FullLanguage 下运行。

+- **清理按设计尽力而为**——`dispose()` 会尝试全部临时撤销并把失败聚合为 `AggregateError`；清理失败可能留下随机目录及其仅含临时 SID 的 ACE。进程退出后，不会再有令牌携带该 SID，因此残留保持失效，直到 OS 临时目录卫生或手动移除目录将其回收。
+- **常驻工作区 ACE 是不可见残留。** 工作区改名会派生新的 SID；旧路径上的旧 ACE 留在原地（失效、仅含写入 SID），未来的清理命令可以回收它们。
+- **NULL-DACL 目录在 grant+revoke 往返下不保持身份。** 带 NULL DACL 的目录意味着「所有人完全控制」；`grantWrite` 从该 null 构建新 ACL，撤销往返后留下的是 EMPTY（全部拒绝）DACL 而非原始 NULL DACL。真实工作区与临时目录都带真实 DACL，因此这仍是记录在案的边界情形。
+- **受限孙进程的管道 stdio 捕获不可用。** libuv 的管道 stdio 用的是 NAMED pipe，其 client 端打开所请求的写访问没有任何 restricting SID 被授予（是 Win32 层的默认 SD 模板，而非令牌默认 DACL），因此受限进程内 `spawn(..., { stdio: 'pipe' })` 以 EPERM 失败；继承与忽略 stdio 的 spawn 可用，匿名管道（PowerShell 的管道）因受限令牌默认 DACL 携带 restricting SID 全权 ACE 而可用。
+- **授权物化是急切的全树传播。** 在带可继承 ACE 的目录上调用 `SetNamedSecurityInfoW` 会立即遍历每个后代（大型工作区树上以数十秒计）；按工作区身份每台机器每个工作区只付一次，精确 ACE 跳过让后续每次供给都很便宜。
+- **读侧隔离与网络策略不在范围内**——`WRITE_RESTRICTED` 只交叉检查写访问；将此后端与读侧策略配对以获得更强隔离。
+- **宽目录与 FAT 卷警告已推迟；FAT 类目标保持可写。** UI 侧警告尚未实现，FAT 卷作为授权根会大声失败，而授权根之外的 FAT 类目标没有安全描述符，因此在两种受限模式下都可写；FAT 被视为遗留残留。
+- **PowerShell 语言模式因受限模式而异。** 在 `read-only` 下，PowerShell 无法在临时目录中创建 AppLocker 探针文件，因此会保守地以 ConstrainedLanguage 启动（`Add-Type`、非核心 .NET 静态调用、COM 与反射失败）；交付的 `workspace-write` 路径可让探针完成，因此除非主机范围的 WDAC/AppLocker 策略另有规定，否则 pwsh 保持 FullLanguage，而直接使用 `AclSandbox` 并配置 `tempDir: null` 时则没有这一保证。这一区别属于 PowerShell 启动行为，不是 ACL 写入边界的一部分。

-Process-sandbox Service Definition. Owns the `ctx.sandbox` service contract ([`SandboxProvider`](src/index.ts)) and the confinement vocabulary the harness shares: `SandboxMode` (`read-only` / `workspace-write` / `danger-full-access`, file effects only), `SandboxEnforcement` (`full` / `partial`, per kernel ABI), `SandboxExecutionPolicy` (the complete per-call mode + workspace root), `SandboxPolicy` (its confined subset), and the fail-closed `SANDBOX_UNAVAILABLE` error. As the Service Definition role of the [capability-seam split](../../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.md), it depends only on cordis (+ the harness error base), never on a backend.
+## Summary
 
-The contract in one line: `ctx.sandbox.confine(argv, policy)` returns the argv to spawn INSTEAD of your own — wrapped so the process (and everything it spawns) runs confined — plus the selected backend's enforcement completeness, denial dialect (`denialSignatures`), and structured runner-failure evidence (`runnerFailureRules`); when no backend is usable it throws rather than passing the argv through unconfined. The [core type catalog](../../../docs/subsystems/sandbox.md#wrapped-argv-and-classification-dialects) owns the exact classifier shape.
+`dsh-sandbox` confines same-world subprocesses to a file-effect policy: commands run `read-only`, write only under the session workspace (`workspace-write`), or run unrestricted (`danger-full-access`), and every confined execution runs under a per-call policy. The bash and pwsh executors consume it, so a command — and everything it spawns — runs confined without the consumer knowing which platform runner is behind it. When the requested mode cannot be enforced, the call fails closed with a `SANDBOX_UNAVAILABLE` error instead of running unconfined. A denied call can request a strictly wider mode that a human approves once. Confinement is same-world only — backends share the host kernel and filesystem, while containers, microVMs, and remote executors replace whole capabilities instead.
 
-Policy rides the call, not the provider: two consumers may confine under different policies at the same instant (bash under `read-only` while a confined child agent keeps its state directory writable), and an approved escalated retry is just a new call with a wider policy.
+## Table of Contents
 
-**Same-world confinement only.** A backend shares the host's filesystem and kernel (`bwrap`, Landlock, Seatbelt); `workspaceRoot` names the filesystem-canonical real host directory. Workspace identity is resolved before lexical normalization, so a valid cwd containing `symlink/..` grants the directory where `chdir` actually lands rather than an unrelated lexical parent. Containers, microVMs, and remote executors are NOT backends of this seam — they replace the Service Providers for whole capability seams (`ctx.shell`, `ctx.fs`) as environment-coherent groups. The boundary and its rationale: [the sandbox Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md).

-Implementations: [`@deepseek-ai/dsh-sandbox-local`](../sandbox-local/) (Linux: `bwrap`, else the per-platform Landlock launcher; macOS: `sandbox-exec`/Seatbelt). Consumers: [`@deepseek-ai/dsh-bash-sandbox`](../../shell/bash-sandbox/) (wraps `['bash', '-c', command]`).
+-----
 
+<a id="use-this-package"></a>
+## Use this package
+
+Compose this service with one backend and a confined consumer, and every command the consumer runs executes under the policy you resolve — you see only the confinement result and its enforcement completeness, never the platform runner.
+
+### When to choose it
+
+Choose this package when a composition confines subprocesses on the host: it is the contract the local backends and the confined executors both implement, so mounting `sandbox-local` behind `ctx.sandbox` and a confined executor behind `ctx.shell` gives every bash or pwsh call a confined default. Choose something else when the process must run in an isolated environment — a container, microVM, or remote executor replaces the whole `ctx.shell`/`ctx.fs` capability rather than adding a backend here.
+
+### Confining a command
+
+Mount the service with a backend and a confined executor; the [base bundle](../../bundle/base/cordis.patch.yml) owns the shipped composition.
+
+```yaml
+- id: sandbox
+  name: '@deepseek-ai/dsh-sandbox-local'     # the per-platform backend provider (ctx.sandbox)
+- id: sandbox-policy
+  name: '@deepseek-ai/dsh-sandbox-policy'    # the deployment default mode and workspace-write root
+  config:
+    mode: workspace-write                    # the deployment default every session starts from
+    workspaceRoot: !!js process.cwd()        # the boundary workspace-write may write under
+- id: bash
+  name: '@deepseek-ai/dsh-bash-sandbox'      # the confined executor behind ctx.shell
+```
+
+With this composition, a bash call runs confined under `workspace-write`: writes inside the workspace succeed, writes outside it are denied, and the model can recover through the escalation flow below.
+
+### Modes and enforcement
+
+The mode names the file effects a command may perform; enforcement completeness reports how fully the backend governs them.
+
+| Mode | Effect |
+|---|---|
+| `read-only` | Denies writes except required sinks such as `/dev/null` |
+| `workspace-write` | Allows writes under the workspace root plus a backend-defined temp area |
+| `danger-full-access` | Bypasses confinement; the consumer spawns its original argv |
+
+Enforcement is reported per call: `full` means the backend governs every promised file effect, while `partial` means an active backend or older kernel ABI governs only a subset — the Windows ACL rung and older Landlock ABIs are the current partial cases, so a consumer that requires the absolute boundary can reject or surface them.
+
+### Denied calls and escalation
+
+When a confined call is denied, the operation reports a denial marker naming the mode — `[sandbox: file access denied under <mode> mode]` — and, when the composition advertises escalation, an escalation hint. The model may retry the exact call once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a `justification`; the user sees one approval prompt and can allow once, reject, or cancel. The escalation must be strictly wider than the call's effective mode, and it applies to that one call only.
+
+### Fail-closed behavior
+
+When no backend can enforce the requested mode, the call fails with `SANDBOX_UNAVAILABLE` rather than running unconfined; the error text names the missing platform runner. A backend that fails after starting also reports a structured runner-failure signature, so a broken sandbox is distinguishable from a command failure.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the contract and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+- **Same-world by contract.** `ctx.sandbox` wraps argv under a host-path file policy; containers, microVMs, and remote execution replace the surrounding capability seam instead.
+- **Policy rides the call.** `SandboxPolicy` is carried per call, never fixed on the provider: two consumers may confine under different policies at the same instant, and an escalated retry is a new call with a wider policy. Defaulting and resolution are explicit consumer steps.
+- **Fail closed.** `confine()` returns enforcing argv or throws `SandboxUnavailableError`; silent unconfined passthrough is forbidden, and functional probes arbitrate multi-runner chains.
+- **One vocabulary for denial and escalation.** The marker and hint texts and the strictly-wider ladder live here so the bash and fs families cannot drift apart.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `SandboxProvider` service, mode/enforcement/policy types, fail-closed error |
+| [`src/escalation.ts`](src/escalation.ts) | Escalation vocabulary: wider-mode ladder, argument validation, denial and hint markers, approval choreography |
+| [`src/roots.ts`](src/roots.ts) | Writable-root derivation shared by the Seatbelt profile and the in-process fs fence |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; the abstract seam registers no event or data relation) |
+
+### Escalation choreography
+
+The ladder is a closed table — `read-only` may escalate to `workspace-write` or `danger-full-access`, `workspace-write` only to `danger-full-access` — checked at execution, never baked into a tool schema, whose enum stays the closed target vocabulary. [`approveEscalation`](src/escalation.ts) validates the `sandbox_permissions`/`justification` pairing, rejects non-widening requests without prompting a human, and maps every approval outcome to its own error before anything executes.
+
+### Writable roots
+
+`workspace-write` means "the workspace root plus the host temp areas": `writableRoots` derives that allow-list canonically, resolving symlinks and deduplicating, so the Seatbelt profile and the in-process fs fence grant exactly the same roots.

 ## Known Limitations and Deferred Work
 
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define when the seam is a poor fit or needs special operational care. They are current package constraints, not a general sandbox comparison or a task backlog.
+
 - **File effects are the whole policy vocabulary** — the seam expresses no network, process, syscall, device, or credential restrictions.
 - **Same-world confinement only** — containers, microVMs, and remote execution require replacing capability implementations rather than adding a provider here.
-- **Denial reporting is a stderr dialect** — the seam returns backend signatures instead of a typed runtime denial channel, so consumers that need classification must infer it from the child process's output.
-- **Runner diagnostics are in-band** — exit status plus stderr evidence cannot prove which process wrote a matching line, so a confined child that deliberately mimics its runner can cause an availability/diagnostic false attribution. This cannot bypass confinement; an out-of-band runner-status channel is deferred.

-进程沙箱 Service Definition。负责定义 `ctx.sandbox` 服务约定（[`SandboxProvider`](src/index.ts)）与 harness 共享的限制词汇：`SandboxMode`（`read-only`／`workspace-write`／`danger-full-access`，仅限文件操作）、`SandboxEnforcement`（`full`／`partial`，针对每种内核 ABI）、`SandboxExecutionPolicy`（每次调用的完整模式及工作区根目录）、`SandboxPolicy`（其中受限制的子集），以及故障时拒绝放行的 `SANDBOX_UNAVAILABLE` 错误。作为[能力 seam 拆分](../../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.zh.md)中的 Service Definition 角色，它只依赖 cordis（及 harness 错误基类），绝不依赖后端。
+## 概述
 
-用一句话概括约定：`ctx.sandbox.confine(argv, policy)` 返回用于 spawn、应当取代调用方原始 argv 的 argv。返回值经过包装，使进程及其派生的所有进程都在限制下运行；还会附带所选后端达到的强制执行完整度、拒绝方言（`denialSignatures`）和结构化 runner 失败证据（`runnerFailureRules`）。没有可用后端时，它会抛出异常，绝不会原样传递 argv 使其不受限制地运行。[核心类型目录](../../../docs/subsystems/sandbox.zh.md#wrapped-argv-and-classification-dialects)负责定义分类器的精确结构。
+`dsh-sandbox` 将同世界子进程限制在文件效果策略之下：命令以 `read-only` 运行、只能写入会话工作区（`workspace-write`）或不受限制地运行（`danger-full-access`），每次受限执行都遵循一份逐调用策略。bash 与 pwsh 执行器直接消费它，因此命令及其派生的所有进程都在限制下运行，消费方无需知道背后是哪个平台 runner。无法强制执行所请求的模式时，调用以 `SANDBOX_UNAVAILABLE` 错误快速失败，绝不会不受限制地运行。被拒绝的调用可以请求一个由人类批准一次、严格更宽的模式。隔离仅限同世界——后端与宿主共享内核和文件系统，容器、microVM 与远程执行器会替换整个能力。
 
-策略随调用传递，而不属于提供方：两个消费方可以同时按不同策略施加限制（bash 使用 `read-only`，而受限制的子 agent（智能体）保持其状态目录可写）；获批的升权重试只是使用更宽策略发起的新调用。
+## 目录
 
-**只支持与宿主共享文件系统和内核的限制。** 后端与宿主共享文件系统和内核（`bwrap`、Landlock、Seatbelt）；`workspaceRoot` 指向文件系统规范化后的真实主机目录。系统先解析工作区所指的目录，再做词法规范化，因此包含 `symlink/..` 的有效 cwd 会授权 `chdir` 实际到达的目录，而非无关的词法父目录。容器、microVM 与远程执行器都不是该 seam 的后端：它们会以环境一致的分组替换整个能力 seam 的 Service Provider（`ctx.shell`、`ctx.fs`）。边界及其设计理由见[沙箱 Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.zh.md)。

-实现：[`@deepseek-ai/dsh-sandbox-local`](../sandbox-local/)（Linux：`bwrap`，否则使用相应平台的 Landlock launcher；macOS：`sandbox-exec`／Seatbelt）。消费方：[`@deepseek-ai/dsh-bash-sandbox`](../../shell/bash-sandbox/)（包装 `['bash', '-c', command]`）。
+-----
 
+<a id="use-this-package"></a>
+## 使用本包
+
+将此服务与一个后端和一个受限消费方组合，消费方运行的每条命令都会在你解析的策略下执行——你只看到隔离结果及其强制执行完整度，永远看不到 runner。
+
+### 何时选择
+
+当组合需要在宿主机上隔离子进程时选择本包：本地后端与受限执行器都实现这个约定，因此在 `ctx.sandbox` 后挂载 `sandbox-local`、在 `ctx.shell` 后挂载受限执行器，就能让每次 bash 或 pwsh 调用都有受限默认值。当进程必须在隔离环境中运行时请另选方案——容器、microVM 或远程执行器会替换整个 `ctx.shell`/`ctx.fs` 能力，而不是在这里添加后端。
+
+### 隔离命令
+
+挂载服务、后端与受限执行器；[base bundle](../../bundle/base/cordis.patch.yml)拥有随附组合。
+
+```yaml
+- id: sandbox
+  name: '@deepseek-ai/dsh-sandbox-local'     # the per-platform backend provider (ctx.sandbox)
+- id: sandbox-policy
+  name: '@deepseek-ai/dsh-sandbox-policy'    # the deployment default mode and workspace-write root
+  config:
+    mode: workspace-write                    # the deployment default every session starts from
+    workspaceRoot: !!js process.cwd()        # the boundary workspace-write may write under
+- id: bash
+  name: '@deepseek-ai/dsh-bash-sandbox'      # the confined executor behind ctx.shell
+```
+
+使用该组合时，bash 调用在 `workspace-write` 下受限运行：工作区内写入成功，工作区外写入被拒绝，模型可以通过下面的升权流程恢复。
+
+### 模式与强制执行
+
+模式指明命令可以执行的文件操作；强制执行完整度报告后端对这些操作的管辖程度。
+
+| 模式 | 效果 |
+|---|---|
+| `read-only` | 拒绝写入，必需 sink（如 `/dev/null`）除外 |
+| `workspace-write` | 允许写入工作区根目录及后端定义的临时区域 |
+| `danger-full-access` | 绕过隔离；消费方直接 spawn 原始 argv |
+
+强制执行逐调用报告：`full` 表示后端管辖模式承诺的每个文件操作，`partial` 表示活动后端或较旧的内核 ABI 只管辖子集——Windows ACL 档与较旧的 Landlock ABI 是当前的部分强制执行情形，需要绝对边界的消费方可以拒绝或向上暴露它们。
+
+### 被拒绝的调用与升权
+
+受限调用被拒绝时，操作会报告指明模式的拒绝标记——`[sandbox: file access denied under <mode> mode]`——组合声明升权能力时还会给出升权提示。模型可以用 `sandbox_permissions`（足以放行的最窄更宽模式）加 `justification` 重试一次完全相同的调用；用户会看到一次审批提示，可以选择允许一次、拒绝或取消。升权必须严格宽于调用的生效模式，且只作用于该次调用。
+
+### 故障关闭行为
+
+没有后端能强制执行所请求的模式时，调用以 `SANDBOX_UNAVAILABLE` 失败，而不是不受限制地运行；错误文本会指明缺失的平台 runner。启动后失败的后端还会报告结构化的 runner 失败签名，因此损坏的沙箱可以与命令失败区分开。

+
+### 设计理念
+
+- **按约定限同世界。** `ctx.sandbox` 在宿主路径文件策略下包装 argv；容器、microVM 与远程执行会替换周边能力 seam。
+- **策略随调用传递。** `SandboxPolicy` 逐调用携带，绝不在提供方上固定：两个消费方可以同时按不同策略隔离，获批的升权重试只是用更宽策略发起的新调用。默认与解析是消费方显式步骤。
+- **故障关闭。** `confine()` 返回受强制的 argv，或抛出 `SandboxUnavailableError`；绝不允许静默无限制放行，功能探测用于仲裁多 runner 链。
+- **统一的拒绝与升权词汇。** 标记与提示文本以及严格更宽阶梯都放在这里，使 bash 与 fs 家族不会漂移。

+### 升权编排
+
+阶梯是封闭表——`read-only` 可升权到 `workspace-write` 或 `danger-full-access`，`workspace-write` 只能升权到 `danger-full-access`——在执行时检查，绝不写入工具 schema，schema 的枚举保持封闭的目标词汇。[`approveEscalation`](src/escalation.ts) 校验 `sandbox_permissions`/`justification` 配对、不提示人类就拒绝非加宽请求，并在任何执行前把每个审批结果映射到各自的错误。

+### 可写根目录
+
+`workspace-write` 意味着「工作区根目录加宿主临时区域」：`writableRoots` 以规范化方式推导该白名单，解析符号链接并去重，使 Seatbelt profile 与进程内 fs 栅栏授予完全相同的根目录。

 # schedule/ — Session-local reminders
 
 English | [中文](README.zh.md)
 
-The Schedule family owns reminders whose durable state lives in the original Session log. A process-local owner waits only while that Session has a live root Agent; cold Sessions resume overdue work when they become live again and never imply an external notification channel.
+## Summary
+
+The schedule group provides session-local reminders for a running conversation: ask the agent to remind you later, at an absolute time, or on a fixed interval, and each reminder arrives as an ordinary message in the same conversation when it comes due. It contains one package with three tools — create, list, and cancel — and no UI or service interface of its own. Reminders survive restarts but stay inside the session: there is no email, SMS, or push notification. This page maps the group; the package README owns the per-package contract.

 # @deepseek-ai/dsh-schedule
 
 English | [中文](README.zh.md)
 
-`dsh-schedule` gives future live root Agents three Session-scoped tools for durable reminders. Version 1 accepts positive safe-integer `after_seconds` delays, explicit absolute `at` targets, and fixed-rate `every_seconds` intervals of at least five minutes. The Session event log owns reminder state; timers, tool values, and model follow-ups are disposable projections of that log.
+## Summary
 
-## Composition
+`dsh-schedule` gives your session durable reminders: ask the model to remind you later, and the reminder comes back as an ordinary follow-up message in the same conversation. You can schedule a one-time reminder after a delay or at an absolute time, or a repeating reminder on a fixed interval, and you can list what is still pending or cancel a reminder. Reminders survive restarts: an already-live idle agent can deliver due work immediately, while a closed or cold session keeps it overdue until a future live root agent resumes the session. Delivery stays inside the session, with no email, SMS, or push notification. It is an opt-in Web capability; load the Schedule overlay to enable the reminder tools.
 
-Load this function plugin after `ctx.sessions`, `ctx.agents`, `ctx.tools`, `ctx.sessionPersistence`, and the persistence listener that implements Session flushes. Static injection makes a missing persistence service a composition error. The plugin listens only to later `agent/created` events, installs on runtime roots, and registers all tools through the exact `agent.ctx`. Agents that already existed when the plugin loaded and runtime children do not receive Schedule.
+## Table of Contents
 
-Time-context is not a Schedule dependency. A composition may mount `@deepseek-ai/dsh-time-context` so the model can interpret natural language in the browser's request-local zone, as the official Schedule Web overlay does. The model must still pass an explicit offset or `time_zone` to `schedule_create`; Schedule never imports or infers from model context.

+- [Further Exploration](#further-exploration)
+- [Model Experience](#model-experience)
+- [Known Limitations and Deferred Work](#known-limitations-and-deferred-work)
+- [Dev Note](#dev-note)
 
-Every operation that reads or decides from the Schedule fold first awaits `ctx.sessions.flush(session)`. A missing, rejected, or detached persistence path returns `persistence_uncertain`; it never turns an unconfirmed live suffix into a list or not-found answer. A successful create or actual delete also awaits a post-append barrier before confirming the mutation.
+-----
 
-## Durable state
+<a id="use-this-package"></a>
+## Use this package
 
-The package owns the strict version-1 `schedule/change` create, delete, and dispatch union. Every create record contains a stable Session-local `ScheduleId`, the trimmed prompt, and a four-digit-year RFC 3339 UTC `scheduledAt`. An `after` record also stores `afterSeconds`; an `at` record stores no copy of its submitted offset, local calendar fields, or interpreting zone; an `every` record stores `everySeconds` and treats `scheduledAt` as the earliest creation-anchor-aligned occurrence not yet dispatched. Delete and one-shot dispatch carry only the id. Every dispatch adds `acceptedAt`, from which replay advances directly to the first anchor-aligned target after that decision time.
+Use Schedule when you want a reminder to arrive as a message in the same conversation — for example, "remind me in 30 minutes to follow up on the migration" or "check back every hour while this build runs". The agent creates, lists, and cancels reminders through its ordinary tools; you only enable the overlay once.
 
-Replay rejects unknown versions, extra fields, reused ids, mismatched one-shot or Every dispatch shapes, and delete or dispatch transitions against inactive records. Normal Sessions fold the complete log. A fork folds only `session.events.slice(session.header.seedLength ?? 0)`, so it does not inherit its parent's reminders. The package's `./invariant` companion applies the same policy to existing logs and candidate events.
+### When to choose it
 
-## Absolute-time input
+Choose Schedule when you want reminders delivered as messages in the same live conversation. Avoid it when delivery must reach you outside the session — there is no email, SMS, push, or browser notification — or when you need calendar-style rules such as "every weekday at 9": repeating reminders run on a fixed interval only.
 
-The `at` selector is either a strict `YYYY-MM-DDTHH:mm:ss[.S|.SS|.SSS](Z|±HH:MM)` string or `{ date: "YYYY-MM-DD", time: "HH:mm:ss[.S|.SS|.SSS]", time_zone: string }`. The string identifies an instant through `Z` or its numeric offset. The local form always requires explicit `UTC` or a valid IANA Area/Location zone. Missing `time_zone`, offset-free strings, extra keys, normalized calendar dates, invalid offsets, and non-future targets are rejected.
+### Enable Schedule
 
-Schedule owns deterministic calendar normalization. Local times inside a daylight-saving gap are rejected. An overlap chooses its first, earlier instant. A successful create retains only canonical UTC `scheduledAt`; no Schedule path reads the browser, Session header, model time-context, connection, or process time zone.
+Add the Schedule overlay to a `dsh web` session; the reminder tools then appear in the conversation and the model can use them right away:
 
-## Management tools
+```sh
+dsh web --patch apps/cli/config/examples/schedule/cordis.yml
+```
 
-The generated [tool catalog](../../../docs/tool-catalog.md) owns the argument and output schemas for `schedule_create`, `schedule_list`, and `schedule_delete`. Their canonical values use camelCase record fields even though model input uses `after_seconds` and `time_zone`.
+Success looks like this: ask the model "remind me in 10 minutes to review the PR", and it replies with the reminder's id, its target time, and a `scheduled` state. If storage cannot be confirmed at that moment, the tool reports `persistence_uncertain` and suggests re-listing instead of claiming success.
 
-One Agent-scoped queue serializes each accepted management transaction and the live owner's due transaction from preflight through any post-append barrier. `schedule_create` requires exactly one of `after_seconds`, `at`, or `every_seconds`, validates shape-only failures before entering the queue, then checkpoints, allocates a never-reused id, appends create, and checkpoints again. `schedule_list` returns active records in creation order with `state: "scheduled" | "overdue"` and `deliveryMode: "session-local"`. `schedule_delete` rejects an empty or whitespace-padded id before the queue and appends only for an active id; an unknown or terminal id returns `{ id, deleted: false, code: "schedule_not_found" }` after preflight.
+Enable the overlay before starting the session you want reminders in: a session that was already running when the overlay loaded does not have the reminder tools.
 
-Every successful management preflight also asks the live owner to recompute. This recovers a retained create or delete batch after a previous post-append barrier returned `persistence_uncertain`, without a Schedule-specific persistence-retry timer.
+### Schedule a reminder
 
-The closed version-1 domain error codes are `invalid_prompt`, `invalid_selector`, `invalid_rule`, `invalid_time_zone`, `not_future`, `time_out_of_range`, `frequency_too_high`, `corrupt_schedule_log`, `persistence_uncertain`, and `internal_error`. Diagnostics are stable and do not expose backend exceptions. Rendered content is deterministic JSON of the canonical value; generic tool-result policy remains responsible for any model-facing spill behavior.
+One-time reminders come in two forms: after a delay — for example "in 30 minutes" — or at an absolute time, given either as an instant with an explicit offset such as `2026-09-01T15:00:00+08:00` or as a local date and time with a named zone such as `Europe/Berlin` (the browser's zone applies only when the time-context overlay is present). Repeating reminders run on a fixed interval of at least 5 minutes and stay aligned to the time you first set them. Every reminder needs content to show when it fires.
 
-## Delivery lifecycle
+A successful create returns the reminder with its id, target time, state, and delivery mode; `schedule_list` shows all pending reminders in the order you created them; canceling by id removes a pending reminder, and an unknown or already-finished id reports `schedule_not_found` without changing anything.
 
-The live owner derives the earliest target from the durable fold. It splits waits longer than the Node timer range and rereads the wall clock after every wake, so a rollback cannot fire early and a forward jump makes the record overdue. Due one-shots have priority and enter one later turn at a time. When no one-shot is due, all overdue Every records form one batch in target and creation order.
+Input that cannot become a reminder — an empty prompt, more than one selector, an invalid time zone, a non-future or out-of-range time, a repeating interval below 5 minutes — returns a stable error code instead of succeeding. The generated [tool catalog](../../../docs/tool-catalog.md#deepseek-aidsh-schedule) owns the exact arguments each tool accepts.
 
-An overdue reminder first checkpoints persistence. If a turn or another maintenance task owns the Agent, `runMaintenance()` rejects the idle-phase claim; the record stays active and the owner retries after `whenIdle()`. A successful maintenance task refolds, samples one decision time, builds the appropriate fixed framing, synchronously queues `followup()`, and appends dispatch before releasing the phase. A one-shot appends its id. Each Every record in a batch appends its id plus the same `acceptedAt`; integer arithmetic selects that record's latest due creation-anchor-aligned occurrence and advances it directly to the first future target. Missed intervals are never enumerated or replayed, distinct overdue records each contribute one occurrence, and there is no shared recurrence gate. Waking input remains parked until release, after which the owner checkpoints dispatch.
+### When reminders fire
 
-The follow-up opens a normal later turn after the Agent becomes fully idle; it never steers or interrupts the current conversation. Its assistant output appears through the ordinary transcript, with no independent receipt or Schedule-specific browser UI. Dispatch means the follow-up was queued and recorded, not that the model succeeded or the user read the answer.
+Due reminders appear as ordinary follow-up messages after the conversation becomes idle; the agent never interrupts a running turn. An already-live idle agent can claim maintenance and deliver immediately without another resume. One-time reminders fire before any repeating batch, and several repeating reminders due at once arrive together in one message ordered by time. If the session is closed or cold when a reminder comes due, it stays overdue until a future live root agent resumes the session — nothing is sent outside the session. A repeating reminder that missed intervals while the session was away presents only its latest due occurrence, not a backlog.
 
-Framing or synchronous follow-up failure writes no dispatch. An append failure faults that owner because the message may already be queued; a barrier rejection leaves dispatch pending for a later ordinary preflight. Agent or plugin disposal cancels timers, stops new work, and awaits in-flight preflights and idle waits without deleting durable records.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the plugin and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Scope and composition
+
+The plugin declares `inject = ['agents', 'sessions', 'tools', 'sessionPersistence']`, so a missing persistence service is a composition error. It observes only `agent/created` events published after it loads, installs on those root Agents, and registers all three tools through the exact `agent.ctx`; Agents already live at load time and runtime children never receive Schedule.
+
+Time-context is not a Schedule dependency. The official Web overlay mounts `@deepseek-ai/dsh-time-context` so the model can interpret natural language in the browser's request-local zone, but the model must still pass an explicit offset or `time_zone` to `schedule_create`; Schedule never imports or infers from model context.
+
+### Design philosophy
+
+The package rests on one separation and three commitments:
+
+- **The Session log owns the state.** Version-1 `schedule/change` events are the only durable authority; timers, tool values, and follow-ups are disposable projections rebuilt from the fold.
+- **Strict replay.** The decoder rejects unknown versions, extra fields, reused ids, mismatched dispatch shapes, and transitions against inactive records, so a corrupt stream fails loudly instead of deriving wrong views.
+- **Persistence before decision.** Every read or decision awaits the shared Session flush barrier, and create and delete confirm only after a second post-append barrier.
+- **Session-local delivery only.** No external channel, no cold-session scheduler, and no receipt: due work enters the same conversation or stays active.
+

+
+### Durable state and replay
+
+A normal Session folds its complete event stream. A fork folds only `session.events.slice(session.header.seedLength ?? 0)`, so a child never inherits its parent's reminders. Every create record carries a stable Session-local `ScheduleId`, the trimmed prompt, and a four-digit-year RFC 3339 UTC `scheduledAt`; an `after` record also stores `afterSeconds`, an `at` record stores no copy of its submitted offset or local fields, and an `every` record stores `everySeconds` with `scheduledAt` as the earliest creation-anchor-aligned occurrence not yet dispatched. Delete and one-shot dispatch carry only the id; an `every` dispatch adds `acceptedAt`, and replay advances directly to the first anchor-aligned target after that decision time.
+
+### Time validation
+
+Calendar normalization is deterministic. Local times inside a daylight-saving gap are rejected; an overlap chooses its first, earlier instant. No Schedule path reads the browser, Session header, model time-context, connection, or process time zone, so replay never depends on ambient time-zone state.
+
+### Management pipeline
+
+One Agent-scoped queue serializes each accepted management transaction with the live owner's due transaction from preflight through any post-append barrier. `schedule_create` checkpoints, allocates a never-reused id, appends the create event, and checkpoints again; a cancelled caller stops before append. Every successful management preflight also asks the live owner to recompute, which recovers a retained create or delete batch after a previous post-append barrier returned `persistence_uncertain`.
+
+Every read or decision from the fold first awaits `ctx.sessions.flush(session)`; a missing, rejected, or detached persistence path returns `persistence_uncertain`, and create and an actual delete await a second barrier after append before confirming the mutation. Shape-only failures are validated before the serialized transaction. Input, time, and durability failures return a closed set of stable version-1 error codes; the closed union and each code's conditions live in [`src/tools.ts`](src/tools.ts).
+
+### Live owner
+
+The owner splits long waits into bounded timer segments and rereads the wall clock after every wake. Due work claims the idle maintenance phase, samples one decision time, builds the complete escaped framing before `followup()`, appends dispatch only after synchronous enqueue returns, releases maintenance, and then awaits durability. Missed fixed-rate intervals are never enumerated: integer arithmetic selects each record's latest due creation-anchor-aligned occurrence and advances it directly to the first future target.
+
+An overdue reminder first checkpoints persistence, then claims the Agent's idle maintenance phase through `runMaintenance()`; if a turn or another maintenance task owns the Agent, the claim is rejected, the record stays active, and the owner retries after `whenIdle()`. A successful maintenance task refolds, samples one decision time, builds the fixed framing, synchronously queues `followup()`, and appends the dispatch before releasing the phase. Dispatch means the follow-up was queued and recorded, not that the model succeeded or the user read the answer. Framing or synchronous follow-up failure writes no dispatch; an append failure faults the owner because the message may already be queued; a barrier rejection leaves dispatch pending for a later ordinary preflight. Agent or plugin disposal cancels timers and stops new work without deleting durable records.

 # @deepseek-ai/dsh-schedule
 
 [English](README.md) | 中文
 
-`dsh-schedule` 为未来创建的 live 根 agent（智能体）提供 3 个会话范围内的工具，用于管理持久提醒。版本 1 接受正的安全整数 `after_seconds` 延时、显式绝对时间 `at` 目标，以及至少 5 分钟的固定速率 `every_seconds` 间隔。会话事件日志拥有提醒状态；timer、工具值和模型 follow-up 都是该日志的可丢弃投影。
+## 概述
 
-## 组合
+`dsh-schedule` 为你的会话提供持久的提醒：让模型稍后提醒你，提醒会作为同一会话中的普通 follow-up 消息返回。你可以安排延时后的一次性提醒、绝对时间的一次性提醒，或固定间隔的重复提醒，也可以列出仍待处理的提醒或取消提醒。提醒在重启后依然存在：已经 live 且空闲的 agent 可以立即交付到期工作，而已关闭或 cold 的会话会让提醒保持逾期，直到未来的 live 根 agent 恢复会话。交付只发生在会话内部，没有电子邮件、短信或推送通知。它是可选的 Web 能力；加载 Schedule overlay 即可启用提醒工具。
 
-请在 `ctx.sessions`、`ctx.agents`、`ctx.tools`、`ctx.sessionPersistence`，以及实现 Session flush 的持久化监听器之后加载此函数插件。静态注入会使缺少持久化服务的组合直接失败。此插件只监听后续的 `agent/created` 事件，在运行时根 agent 上安装，并通过完全相同的 `agent.ctx` 注册所有工具。插件加载时已经存在的 agent 与运行时子 agent 不会获得 Schedule。
+## 目录
 
-Time-context 不是 Schedule 的依赖。组合可以挂载 `@deepseek-ai/dsh-time-context`，使模型能够按浏览器的请求本地时区解释自然语言；官方 Schedule Web overlay 正是如此。模型仍必须向 `schedule_create` 传入显式偏移量或 `time_zone`；Schedule 绝不会从模型上下文中导入或推断该值。

-每项从 Schedule 折叠结果读取或作出判断的操作，都会先等待 `ctx.sessions.flush(session)`。持久化路径缺失、拒绝或已分离时，操作返回 `persistence_uncertain`；它绝不会把未经确认的 live 后缀当成列表或未找到结果。成功创建或实际删除后，还会等待追加后的持久化 barrier（屏障）再确认变更。
+-----
 
-## 持久状态
+<a id="use-this-package"></a>
+## 使用本包
 
-此包拥有严格的版本 1 `schedule/change` create、delete 与 dispatch 联合。每条 create 记录都包含稳定的会话本地 `ScheduleId`、已 trim 的提示词，以及使用四位年份的 RFC 3339 UTC `scheduledAt`。`after` 记录还会存储 `afterSeconds`；`at` 记录不会保留所提交的偏移量、本地日历字段或解释该值时所用的时区；`every` 记录存储 `everySeconds`，并把 `scheduledAt` 视为尚未 dispatch 的最早一个创建锚点对齐发生时点。delete 与一次性 dispatch 只携带 id。Every dispatch 还会添加 `acceptedAt`；回放会据此直接推进到该决策时点之后的第一个锚点对齐目标。
+当你希望提醒作为消息出现在同一会话中时使用 Schedule——例如「30 分钟后提醒我跟进迁移」或「构建运行期间每小时检查一次」。agent 会通过它的普通工具为你创建、列出和取消提醒；你只需启用一次 overlay。
 
-回放会拒绝未知版本、额外字段、重复使用的 id、形状不匹配的一次性或 Every dispatch，以及针对非活动记录的 delete 或 dispatch 转换。普通会话折叠完整日志。fork 只折叠 `session.events.slice(session.header.seedLength ?? 0)`，因此不会继承父会话的提醒。此包的 `./invariant` 配套模块会对现有日志和候选事件应用相同策略。
+### 何时选择
 
-## 绝对时间输入
+当你希望提醒以消息形式在同一 live 会话中交付时，选择 Schedule。当交付必须到达会话之外时请避开它——没有电子邮件、短信、推送或浏览器通知——或者当你需要「每个工作日 9 点」这类日历规则时：重复提醒只按固定间隔运行。
 
-`at` selector 可以是严格的 `YYYY-MM-DDTHH:mm:ss[.S|.SS|.SSS](Z|±HH:MM)` 字符串，也可以是 `{ date: "YYYY-MM-DD", time: "HH:mm:ss[.S|.SS|.SSS]", time_zone: string }`。字符串通过 `Z` 或数值偏移量标识一个时刻。本地形式始终要求显式 `UTC` 或有效的 IANA Area/Location 时区。缺少 `time_zone`、不带偏移量的字符串、额外键、需要规范化的日历日期、无效偏移量和非未来目标都会被拒绝。
+### 启用 Schedule
 
-Schedule 负责确定性的日历规范化。落在夏令时缺口内的本地时间会被拒绝；遇到重叠时会选择第一次出现的较早时刻。创建成功后只保留规范化后的 UTC `scheduledAt`；Schedule 的任何路径都不会读取浏览器、Session 标头、模型 time-context、连接或进程时区。
+把 Schedule overlay 添加到 `dsh web` 会话；提醒工具随即出现在会话中，模型可以立即使用它们：
 
-## 管理工具
+```sh
+dsh web --patch apps/cli/config/examples/schedule/cordis.yml
+```
 
-生成的[工具目录](../../../docs/tool-catalog.zh.md)负责 `schedule_create`、`schedule_list` 和 `schedule_delete` 的参数与输出 schema。虽然模型输入使用 `after_seconds` 和 `time_zone`，但其规范值中的记录字段使用 camelCase。
+成功的样子如下：让模型「10 分钟后提醒我审阅 PR」，它会回复提醒的 id、目标时间与 `scheduled` 状态。如果那一刻存储无法确认，工具会报告 `persistence_uncertain` 并建议重新列出，而不是声称成功。
 
-一条 Agent-scoped 队列会将每项已接纳的管理事务与 live owner 的到期事务从 preflight 到任何 post-append barrier 全程串行化。`schedule_create` 要求 `after_seconds`、`at` 与 `every_seconds` 有且只有一项；它会在进入队列前验证只依赖输入形状的失败，随后执行检查点、分配永不复用的 id、追加 create，再次执行检查点。`schedule_list` 按创建顺序返回活动记录，其中包含 `state: "scheduled" | "overdue"` 与 `deliveryMode: "session-local"`。`schedule_delete` 会在进入队列前拒绝空 id 或前后带空白的 id，并只为活动 id 追加事件；未知或已终结的 id 会在 preflight 后返回 `{ id, deleted: false, code: "schedule_not_found" }`。
+请在你想要提醒的会话开始前启用 overlay：overlay 加载时已在运行的会话没有提醒工具。
 
-每次成功的管理 preflight 还会要求 live owner 重新计算。如果先前的 post-append barrier 返回 `persistence_uncertain`，这会恢复所保留的 create 或 delete batch，而无需 Schedule 专属的持久化重试 timer。
+### 安排提醒
 
-版本 1 的封闭领域错误代码包括 `invalid_prompt`、`invalid_selector`、`invalid_rule`、`invalid_time_zone`、`not_future`、`time_out_of_range`、`frequency_too_high`、`corrupt_schedule_log`、`persistence_uncertain` 和 `internal_error`。诊断文本保持稳定，不会暴露后端异常。渲染内容是规范值的确定性 JSON；通用工具结果策略仍负责模型可见内容的 spill 行为。
+一次性提醒有两种形式：延时后——例如「30 分钟后」——或绝对时间，可以给出带显式偏移量的时刻，如 `2026-09-01T15:00:00+08:00`，也可以给出带命名时区（如 `Europe/Berlin`）的本地日期与时间（只有加载 time-context overlay 时才应用浏览器时区）。重复提醒按至少 5 分钟的固定间隔运行，并与你首次设置的时间保持对齐。每条提醒都需要在触发时展示的内容。
 
-## 交付生命周期
+创建成功会返回带 id、目标时间、状态与交付模式的提醒；`schedule_list` 按创建顺序显示所有待处理提醒；按 id 取消会移除待处理提醒，未知或已结束的 id 会报告 `schedule_not_found` 且不改变任何内容。
 
-live owner 从持久折叠结果派生最早的目标。它会拆分超过 Node timer 范围的等待，并在每次唤醒后重新读取墙钟，因此时钟回拨不会提前触发，时钟前跳则会使记录进入 overdue 状态。已到期的一次性提醒优先，每次进入一个后续轮次。没有一次性提醒到期时，所有逾期 Every 记录会按目标时间和创建顺序组成一个批次。
+无法成为提醒的输入——空提示词、多于一个 selector、无效时区、非未来或超出范围的时间、低于 5 分钟的重复间隔——会返回稳定的错误代码而不是成功。生成的[工具目录](../../../docs/tool-catalog.zh.md#deepseek-aidsh-schedule)拥有每个工具接受的精确参数。
 
-overdue 提醒首先为持久化建立检查点。如果 agent 已被某个轮次或另一项 maintenance task 占用，`runMaintenance()` 会拒绝对 idle phase 的认领；记录会保持活动，owner 会在 `whenIdle()` 后重试。获准执行的 maintenance task 会重新折叠、采样一个决策时点、构造相应的固定 framing、同步将 `followup()` 入队，并在释放 phase 前追加 dispatch。一次性提醒只追加 id。批次中的每条 Every 记录都会追加其 id 和相同的 `acceptedAt`；整数运算会选择该记录最新一个已到期且与创建锚点对齐的发生时点，并将记录直接推进到第一个未来目标。系统绝不会枚举或回放错过的间隔；每条不同的逾期记录各贡献一个发生时点，并且不存在共享的周期性准入门控。触发唤醒的 input 会保持 parked，直到 phase 释放；随后 owner 为 dispatch 建立检查点。
+### 提醒何时触发
 
-Agent 完全 idle 后，follow-up 会开启一个普通的后续轮次；它绝不会中途引导或中断当前对话。assistant 输出通过普通 transcript（文本记录）显示，不存在独立回执或 Schedule 专属浏览器 UI。dispatch 表示 follow-up 已入队并被记录，不表示模型成功或用户已读取回答。
+到期提醒会在会话空闲后作为普通 follow-up 消息出现；agent 绝不会中断正在运行的轮次。已经 live 且空闲的 agent 可以认领 maintenance 并立即交付，无需再次恢复。一次性提醒先于任何重复批次触发；同时到期的多条重复提醒会按时间顺序合并为一条消息。如果会话在提醒到期时已关闭或 cold，提醒会保持逾期，直到未来的 live 根 agent 恢复会话——会话之外不会发送任何内容。错过若干间隔的重复提醒只展示最新一个到期发生时点，不展示积压。
 
-framing 构造或同步 follow-up 失败不会写入 dispatch。追加失败会使该 owner 进入故障状态，因为消息可能已经入队；barrier 拒绝会把 dispatch 留给后续普通 preflight。agent 或插件执行资源释放时，会取消 timer、停止新工作，并等待进行中的 preflight 与 idle wait，且不会删除持久记录。

+## 理解实现
+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释插件背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 作用域与组合
+
+插件声明 `inject = ['agents', 'sessions', 'tools', 'sessionPersistence']`，因此缺少持久化服务会直接构成组合错误。它只观察加载后发布的 `agent/created` 事件，在这些根 agent 上安装，并通过完全相同的 `agent.ctx` 注册全部三个工具；加载时已经 live 的 agent 与运行时子 agent 永远不会获得 Schedule。
+
+Time-context 不是 Schedule 的依赖。官方 Web overlay 挂载 `@deepseek-ai/dsh-time-context`，让模型能够按浏览器请求本地时区解释自然语言；但模型仍必须向 `schedule_create` 传入显式偏移量或 `time_zone`；Schedule 绝不会从模型上下文导入或推断该值。
+
+### 设计理念
+
+本包建立在一个分离与三项承诺之上：
+
+- **会话日志拥有状态。** 版本 1 的 `schedule/change` 事件是唯一持久权威；timer、工具值与 follow-up 都是从折叠结果重建的可丢弃投影。
+- **严格回放。** 解码器拒绝未知版本、额外字段、重复使用的 id、形状不匹配的 dispatch 以及针对非活动记录的转换，因此损坏的流会大声失败，而不是派生出错误视图。
+- **先持久化再决策。** 每项读取或决策都等待共享的会话 flush barrier，create 与 delete 只在第二个 post-append barrier 之后才确认。
+- **仅限会话本地交付。** 没有外部渠道、没有 cold 会话调度器、也没有回执：到期工作进入同一会话，否则保持活动。

+### 持久状态与回放
+
+普通会话折叠完整事件流。fork 只折叠 `session.events.slice(session.header.seedLength ?? 0)`，因此子会话永远不会继承父会话的提醒。每条 create 记录都携带稳定的会话本地 `ScheduleId`、已 trim 的提示词与四位年份 RFC 3339 UTC `scheduledAt`；`after` 记录还存储 `afterSeconds`，`at` 记录不保留所提交的偏移量或本地字段，`every` 记录存储 `everySeconds`，并把 `scheduledAt` 视为尚未 dispatch 的最早创建锚点对齐发生时点。delete 与一次性 dispatch 只携带 id；`every` dispatch 会附加 `acceptedAt`，回放直接推进到该决策时点之后的第一个锚点对齐目标。
+
+### 时间校验
+
+日历规范化是确定性的。夏令时缺口内的本地时间会被拒绝；重叠时选择第一次出现的较早时刻。Schedule 的任何路径都不会读取浏览器、会话标头、模型 time-context、连接或进程时区，因此回放永不依赖环境时区状态。
+
+### 管理流水线
+
+一条 agent 范围的队列把每项已接纳的管理事务与 live owner 的到期事务从 preflight 到任何 post-append barrier 全程串行化。`schedule_create` 建立检查点、分配永不复用的 id、追加 create 事件，再次建立检查点；被取消的调用方在追加前停止。每次成功的管理 preflight 还会要求 live owner 重新计算，这会在先前的 post-append barrier 返回 `persistence_uncertain` 后恢复所保留的 create 或 delete 批次。
+
+每项从折叠结果读取或作出判断的操作都会先等待 `ctx.sessions.flush(session)`；持久化路径缺失、被拒绝或已分离时返回 `persistence_uncertain`，create 与实际 delete 在追加后还会等待第二个 barrier 再确认变更。只依赖输入形状的失败会在序列化事务之前被验证。输入、时间与持久化失败会返回一组封闭的稳定版本 1 错误代码；该封闭联合及各代码的触发条件位于 [`src/tools.ts`](src/tools.ts)。
+
+### live owner
+
+owner 把长等待拆分为有界的 timer 段，并在每次唤醒后重新读取墙钟。到期工作认领 idle maintenance phase、采样一个决策时点、在 `followup()` 之前构造完整的转义 framing、只在同步入队返回后追加 dispatch、释放 maintenance，然后等待持久化。错过的固定速率间隔永远不会被枚举：整数运算选择每条记录最新一个已到期且与创建锚点对齐的发生时点，并直接推进到第一个未来目标。
+
+逾期提醒首先为持久化建立检查点，然后通过 `runMaintenance()` 认领 agent 的 idle maintenance phase；如果某个轮次或另一项 maintenance task 已占用 agent，认领会失败，记录保持活动，owner 在 `whenIdle()` 后重试。获准的 maintenance task 会重新折叠、采样一个决策时点、构造固定 framing、同步将 `followup()` 入队，并在释放 phase 前追加 dispatch。dispatch 表示 follow-up 已入队并被记录，不表示模型成功或用户已读取回答。framing 构造或同步 follow-up 失败不会写入 dispatch；追加失败会使 owner 进入故障状态，因为消息可能已经入队；barrier 拒绝则把 dispatch 留给后续普通 preflight。agent 或插件执行资源释放时取消 timer 并停止新工作，但不删除持久记录。

 English | [中文](README.zh.md)
 
-This group contains the protocol stack for driving a Harness runtime from another process. The TypeScript and Python clients both launch `dsh` with a named profile and ordered patches; no package in this group defines a separate application. The [TypeScript SDK decision](../../.agents/notes/implemented/feature/2026-07-27-typescript-sdk-and-sdk-subagent-backend.md) owns the client contract, and the [Python profile-runtime decision](../../.agents/notes/implemented/architecture/2026-08-23-python-sdk-dsh-profile-runtime.md) owns the packaged Python launch.
+## Summary
+
+This group lets another process drive a complete DeepSeek Harness runtime: the JSON-RPC wire protocol defines the messages, the server plugin serves external clients over stdio, and the TypeScript and Python clients launch `dsh` with a named profile and ordered patches. No package in this group defines a separate application or creates developer projects. SDK clients open sessions, send prompts, and observe session events, agent status transitions, and subagent completions as they happen. The TypeScript client is the design twin of the [Python SDK](../../python/README.md), which speaks the same protocol. This page maps the group; each package README owns its per-package contract.

 # @deepseek-ai/dsh-sdk-client
 
 English | [中文](README.zh.md)
 
-The TypeScript client SDK for driving the same-version [`dsh`](../../../apps/cli/README.md) runtime over stdio JSON-RPC. `DeepSeekHarness` is the high-level owned-run API; `HarnessClient` is the lower-level protocol client. The package depends on `@deepseek-ai/dsh` and resolves that installed CLI directly, so ordinary consumers do not discover a runtime executable or maintain a second application configuration. A clean source checkout whose `lib/bin.js` does not exist launches the same package's `src/bin.ts` through its resolved `tsx/esm` loader and an internal patch that omits build-generated Typert contribution loading; the SDK JSON-RPC application does not consume that remote gateway. An installed package uses the complete built entry.
+## Summary
 
-Both client layers accept the same launch fields: `dshBin?`, `profile?` (default `sdk`), ordered `patches?`, `dshHome?`, `processCwd?`, `env?`, and request/initialize/shutdown/disposal timeouts. Caller-relative CLI-module, patch, explicit home, and process-cwd paths become absolute before spawn. The client runs the dsh CLI module through its current Node executable on every platform. An omitted home keeps normal dsh resolution (`DSH_HOME`, then `~/.dsh`); an explicit home overrides the child environment. `env` replaces the child environment when supplied; the client reads either that object or `process.env` when `start()` actually spawns, so mutations before the first start are visible.
+`dsh-sdk-client` lets TypeScript programs drive a DeepSeek Harness runtime as a subprocess over stdio JSON-RPC. With `DeepSeekHarness` you can spawn the runtime, open sessions, send prompts, and collect the final response plus the event and notification streams; `HarnessClient` gives explicit control over the protocol layer. It is the design twin of the [Python SDK](../../../python/README.md), which shares the same runtime peer and protocol. The launch spec is explicit — callers may name the runtime executable via `dshBin`, omitted resolves the same-version `@deepseek-ai/dsh` package's bin, and the client constructs the arguments — so this client suits repository-adjacent TypeScript consumers such as the SDK subagent backend and automation that know which runtime they are launching. It is a pure library: it registers nothing on a Cordis context, and the runtime it spawns is a complete harness whose composition its own `cordis.yml` decides.
 
-Composition customization stays in the profile system. Install persistent bundles and plugin dependencies with `dsh plugin --profile <name> …`, edit that profile's `cordis.patch.yml`, and select it with `profile`. Use `patches` for ordered per-launch overrides. A patch replaces a row's complete config, and a custom profile must retain `@deepseek-ai/dsh-sdk-app` or another SDK server row.

+## Use this package

+Use this client when TypeScript code must drive a complete Harness runtime from another process and you can name the runtime executable explicitly. The common path is minimal: construct a `DeepSeekHarness` with a launch spec, run prompts, and close it so the child process is always reaped.

-The dsh process starts lazily on first use and stays owned across `run()` calls. `close()` (or `await using`) is required. `start()` memoizes the bounded `initialize` handshake, which carries the workspace cwd, provider/model route, optional adapter-owned `reasoningEffort`, and optional positive `maxTokens` output cap. `initializeTimeoutMs` defaults to 10 seconds, and its diagnostic names the selected profile with the retained stderr tail. The server validates the exact route before accepting prompts; omitting the effort preserves the model's own default. When a failed handshake is cleaned up successfully, the instance installs a fresh client so a later call retries with a new process until terminal `close()`. If initialization and SDK-owned cleanup both fail, `start()` rejects with an `AggregateError` whose ordered errors preserve both causes and retains the failed client rather than spawning beside a process whose exit was not proved. The cap applies to each root-agent request and is inherited by in-process descendants; compaction plugins own their separate summary limits. `session(id?)` opens a named or fresh session handle.

+### Lower-level control with HarnessClient
 
-## HarnessClient
+`HarnessClient` is the protocol client under the run API: explicit `start()`, `initialize()`, `prompt()`, `request()`, and `close()`, plus notification subscriptions. `prompt()` returns the queued message id as soon as the runtime accepts it and never waits for agent activity. `subscribe(filter?)` returns a `NotificationSubscription` (awaitable `next()`, non-blocking `tryNext()`, async iteration); `subscribeSessionTree(id)` scopes to one session and the descendants discovered from `subagent.started` lineage edges — the runtime notifies for every session in its context, and scoping is client-side, exactly like the Python SDK.
 
-The low-level client exposes `start()`/`initialize()`/`prompt()`/`request()`/`close()` and notification subscriptions. `prompt()` returns the durable message id after enqueue, not a prompt result. `subscribeSessionTree(id)` scopes the process-wide notification stream to one session lineage. Exported failures are `JsonRpcResponseError`, `RequestTimeoutError`, `SdkProtocolError`, and `TransportClosedError`.
+The client exports typed errors for every failure mode: `JsonRpcResponseError` (a wire error response, code and data preserved), `RequestTimeoutError` (a configured bound elapsed), `SdkProtocolError` (a response outside the documented protocol), and `TransportClosedError` (the runtime is gone — the message carries the exit code and a bounded stderr tail). `close()` requests protocol `shutdown` (bounded by `shutdownTimeoutMs`, default 1000 ms), then walks a stdin-EOF → SIGTERM → SIGKILL ladder until the process has exited; it is idempotent, and a closed client refuses reuse. `HarnessClientOptions.env` replaces the child environment entirely when given (`undefined` inherits the parent's); callers own credential policy — `scrubbedParentEnv` from `dsh-subprocess` is the shared scrub base for isolation-minded launches.
 
-`close()` requests protocol `shutdown` (default bound 1000 ms), then uses stdin EOF → SIGTERM → SIGKILL (`disposeEofGraceMs` 6000, `disposeGraceMs` 3000) until the process exits. This client lives outside any Harness context, so its private process adapter is the documented SDK-managed transport exception to `dsh-subprocess`; generic command/argv launching is package-test machinery, not a consumer interface.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design behind the client; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The client is two layers over one wire: `DeepSeekHarness` (owned runs) over `HarnessClient` (the protocol client), mirroring the Python SDK's layering. It runs outside any harness context, so it spawns the runtime directly rather than through the `dsh-subprocess` service — the seam's documented exception for SDK-managed transports — and its teardown ladder lives in this package. The runtime notifies for every session in its context; session-tree scoping is a client-side filter over `subagent.started` lineage edges.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/api.ts`](src/api.ts) | `DeepSeekHarness` + `HarnessSession`: owned runs, receipt-to-idle collection, `finalResponse` |
+| [`src/client.ts`](src/client.ts) | `HarnessClient`: spawn, handshake, requests, subscription fan-out, typed errors |
+| [`src/dispose.ts`](src/dispose.ts) | Private teardown ladder: stdin EOF → SIGTERM → SIGKILL to actual exit |
+| [`src/types.ts`](src/types.ts) | Launch and timeout options, notification shapes, `RunResult` |
+| [`src/index.ts`](src/index.ts) | Consumer interface: the two client layers and caller-facing types |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant — the peer is a separate runtime process) |
+
+### Owned activity flow
+
+A run subscribes to the session tree, queues the prompt, waits until the prompt's message id appears in a durable `agent/inbox/spliced` receipt, then collects notifications until the whole agent reports `idle`. `finalResponse` is derived from the last `assistant/message` in the collected events. Transport loss, timeout, and protocol violations reject the run; model outcomes remain observable in the event stream without being attributed to one input.
+
+### Errors and teardown
+
+Every failure mode maps to one exported error class — a wire error response, an elapsed request bound, a response outside the documented protocol, or a dead runtime — so callers branch on failure type; the four classes are exported from [src/index.ts](src/index.ts). Teardown is a private, idempotent escalation (stdin EOF → SIGTERM → SIGKILL) in [src/dispose.ts](src/dispose.ts) that ends only at actual process exit.

 # @deepseek-ai/dsh-sdk-client
 
 [English](README.md) | 中文
 
-通过 stdio JSON-RPC 驱动同版本 [`dsh`](../../../apps/cli/README.zh.md) runtime 的 TypeScript client SDK。`DeepSeekHarness` 是高层自有运行 API，`HarnessClient` 是低层协议 client。本包依赖 `@deepseek-ai/dsh` 并直接解析随安装的 CLI，因此普通消费方无需发现 runtime 可执行文件，也无需维护第二套应用配置。干净源码 checkout 中若不存在 `lib/bin.js`，client 会通过已解析的 `tsx/esm` loader 启动同一包的 `src/bin.ts`，并应用一个省略构建期生成 Typert 贡献加载的内部 patch；SDK JSON-RPC 应用不消费该远程网关。已安装包使用完整的构建后入口。
+## 概述
 
-两层 client 接受同一组启动字段：`dshBin?`、`profile?`（默认 `sdk`）、有序 `patches?`、`dshHome?`、`processCwd?`、`env?`，以及请求、初始化、关闭和 dispose 超时。相对调用方的 CLI 模块、patch、显式 home 与进程 cwd 路径会在 spawn 前转为绝对路径。client 会在所有平台上通过自身当前的 Node 可执行文件运行 dsh CLI 模块。省略 home 时保留 dsh 的普通解析（先 `DSH_HOME`，再 `~/.dsh`）；显式 home 会覆盖子进程环境。提供 `env` 时，它整体替换子进程环境；client 会在 `start()` 实际 spawn 时读取该对象或 `process.env`，所以首次启动前的修改会生效。
+`dsh-sdk-client` 让 TypeScript 程序以子进程方式、通过 stdio JSON-RPC 驱动 DeepSeek Harness 运行时。使用 `DeepSeekHarness` 你可以启动运行时、打开会话、发送提示词，并收集最终响应以及事件与通知流；`HarnessClient` 提供对协议层的显式控制。它是 [Python SDK](../../../python/README.zh.md) 的设计孪生，共享同一个运行时对端与协议。启动说明是显式的——调用方可通过 `dshBin` 指定运行时可执行文件，省略时解析同版本 `@deepseek-ai/dsh` 包的 bin，参数由客户端构造——因此本客户端适合仓库近旁的 TypeScript 消费方，如 SDK subagent 后端和知道自己要启动哪个运行时的自动化。它是纯库：不在任何 Cordis 上下文注册，而且它启动的运行时是一个完整 harness，其组成由自己的 `cordis.yml` 决定。
 
-组合自定义属于 profile 系统。使用 `dsh plugin --profile <name> …` 安装持久组合包与插件依赖，编辑该 profile 的 `cordis.patch.yml`，再通过 `profile` 选择。`patches` 用于有序的逐次启动覆盖。patch 会替换配置行的完整 config；自定义 profile 必须保留 `@deepseek-ai/dsh-sdk-app` 或另一个 SDK server 配置行。

+`HarnessClient` 是运行 API 之下的协议客户端：显式 `start()`、`initialize()`、`prompt()`、`request()` 与 `close()`，外加通知订阅。`prompt()` 在运行时接受排队消息后立即返回该消息的 id，绝不等待 agent 活动。`subscribe(filter?)` 返回 `NotificationSubscription`（可等待的 `next()`、非阻塞 `tryNext()`、异步迭代）；`subscribeSessionTree(id)` 把范围限定到一个会话及从 `subagent.started` 血缘边发现的后代——运行时对上下文内每个会话都发通知，范围限定在客户端完成，与 Python SDK 完全一致。
 
-低层 client 提供 `start()`/`initialize()`/`prompt()`/`request()`/`close()` 与 notification 订阅。`prompt()` 返回入队后的持久消息 ID，而不是 prompt 结果。`subscribeSessionTree(id)` 把进程级 notification 流限定到一个 session 血缘。导出的失败类型为 `JsonRpcResponseError`、`RequestTimeoutError`、`SdkProtocolError` 与 `TransportClosedError`。
+本客户端为每种失败模式导出类型化错误：`JsonRpcResponseError`（协议错误响应，保留 code 与 data）、`RequestTimeoutError`（配置的时限已到）、`SdkProtocolError`（响应超出文档化协议）、`TransportClosedError`（运行时已消失——消息携带退出码与有界 stderr 尾部）。`close()` 先请求协议 `shutdown`（受 `shutdownTimeoutMs` 约束，默认 1000 毫秒），然后走 stdin-EOF → SIGTERM → SIGKILL 阶梯直到进程退出；幂等，已关闭的客户端拒绝复用。`HarnessClientOptions.env` 给定时整体替换子进程环境（`undefined` 原样继承父进程环境）；凭据策略归调用方——`dsh-subprocess` 的 `scrubbedParentEnv` 是面向隔离启动的共享擦除基底。
 
-`close()` 先请求协议 `shutdown`（默认上限 1000 毫秒），再执行 stdin EOF → SIGTERM → SIGKILL（`disposeEofGraceMs` 6000、`disposeGraceMs` 3000），直到进程退出。client 位于任何 Harness context 之外，因此其私有进程 adapter 是 `dsh-subprocess` 中记录的 SDK 托管传输例外；通用 command/argv 启动仅是包测试机制，不是消费方接口。

+## 理解实现
+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释客户端背后的设计；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+客户端是同一协议上的两层：`DeepSeekHarness`（自有运行）叠加在 `HarnessClient`（协议客户端）之上，与 Python SDK 的分层一致。它运行在任何 harness 上下文之外，因此直接 spawn 运行时而非经由 `dsh-subprocess` 服务——即该 seam 记录的 SDK 托管传输例外——其关闭阶梯也位于本包。运行时对上下文内每个会话都发通知；会话树范围限定是客户端对 `subagent.started` 血缘边的过滤。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/api.ts`](src/api.ts) | `DeepSeekHarness` + `HarnessSession`：自有运行、回收到 idle 的收集、`finalResponse` |
+| [`src/client.ts`](src/client.ts) | `HarnessClient`：spawn、握手、请求、订阅扇出、类型化错误 |
+| [`src/dispose.ts`](src/dispose.ts) | 私有关闭阶梯：stdin EOF → SIGTERM → SIGKILL 直到真正退出 |
+| [`src/types.ts`](src/types.ts) | 启动与超时选项、通知结构、`RunResult` |
+| [`src/index.ts`](src/index.ts) | 消费方接口：两层客户端与面向调用方的类型 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式配套插件（无运行时不变式——对端是独立运行时进程） |
+
+### 自有活动流程
+
+一次运行会订阅会话树、把提示词排入队列，等待提示词的消息 id 出现在持久的 `agent/inbox/spliced` 回执中，然后持续收集通知，直到整个 agent 报告 `idle`。`finalResponse` 从收集到的事件中最后一条 `assistant/message` 派生。传输丢失、超时与协议违例会使本次运行被拒绝；模型结果仍可在事件流中观察，但不会归属于某一输入。
+
+### 错误与关闭
+
+每种失败模式都映射到一个导出的错误类——协议错误响应、请求时限已到、响应超出文档化协议、运行时死亡——调用方可以按失败类型分支处理；这四个类从 [src/index.ts](src/index.ts) 导出。关闭采用私有的幂等阶梯（stdin EOF → SIGTERM → SIGKILL），位于 [src/dispose.ts](src/dispose.ts)，只在进程真正退出时结束。

+无，因为这是客户端进程库；模型可见行为存在于所 spawn 运行时组合的插件中。
 
 #### KV Cache 影响

-- **所选 profile 可以省略 SDK server**：初始化会在配置的上限失败并写明 profile；请保留 SDK app 组合包或等价 server 配置行。
-- **没有轮次中取消或逐 prompt 结果**：放弃自有活动意味着关闭 runtime；模型结果保留在 session event 中。

+
+
+这些限制说明本客户端何时不合适或需要特别注意。它们是当前包约束，不是与其他 SDK 客户端的对比或任务积压。
+
+- **无捆绑运行时解析**——客户端解析同版本 `@deepseek-ai/dsh` 包（或调用方提供的 `dshBin`）；打包可执行文件的发现留在 Python 侧，直到出现 TypeScript 发行版消费方。
+- **无轮次中取消**——协议层没有提示词取消方法；放弃轮次意味着关闭运行时（见[协议限制](../protocol/README.zh.md#known-limitations-and-deferred-work)）。
+- **没有逐提示词结果**——低层 `prompt()` 只返回入队回执；高层 `run()` 负责从回收到 idle 的收集，放弃该过程意味着关闭运行时。
+- **客户端→服务端通知与服务端→客户端请求**在协议两端都未实现；传输层为未来审批流程保留了承载能力。

-The shared wire protocol for the DeepSeek Harness SDK runtime: one newline-delimited JSON-RPC 2.0 transport class plus the named request, result, and notification types both wire ends speak. The package root enumerates the protocol consumer interface; source modules are not exported as deep imports. The server side is the [`dsh-sdk-jsonrpc-server`](../server/README.md) plugin; clients are [`dsh-sdk-client`](../client/README.md) (TypeScript) and the [Python SDK](../../../python/README.md) (which mirrors these shapes but does not import them). A pure library — no plugin, no Config, no registration.
+## Summary
 
-## Transport
+`dsh-sdk-protocol` lets a DeepSeek Harness runtime and its SDK clients exchange JSON-RPC 2.0 messages over newline-delimited byte streams: one transport class plus the named request, result, and notification types both wire ends speak. The serving side is the [`dsh-sdk-jsonrpc-server`](../server/README.md) plugin; the clients are the TypeScript [`dsh-sdk-client`](../client/README.md) and the [Python SDK](../../../python/README.md), which mirrors these shapes without importing them. Use this package when you implement or debug a wire end: framing rules, method names, payload types, and error semantics all live here. It is a pure library — no plugin, no configuration, no registrations.
 
-`JsonRpcLineTransport` frames JSON-RPC 2.0 over caller-owned byte streams, one compact JSON frame per `\n`-terminated line. Frames with `id` and `method` are requests, `id` alone is a response, `method` alone is a notification; malformed JSON lines are ignored. `start()` attaches stream listeners, `close()` detaches them and rejects pending requests without destroying the streams. Missing request handlers answer `-32601`; handler rejections answer `-32603` with the error message. An error response rejects the pending `request()` with `JsonRpcResponseError`, which preserves the wire `code` and optional `data`. `JsonRpcTransportPeer` is the outbound surface (request/notify) the server class is typed against.

+## Use this package
+
+Use this package when you build or debug an SDK wire end — the serving plugin, a client library, or custom tooling that speaks the SDK protocol. It gives you one transport for JSON-RPC 2.0 over caller-owned byte streams and the typed shapes for every SDK method and notification.
+
+### Framing and transport
+
+Wire one JSON-RPC 2.0 message per `\n`-terminated line over byte streams you own. A frame with both `id` and `method` is a request, `id` alone is a response, and `method` alone is a notification; malformed lines are ignored. Requests with no registered handler answer `-32601`, handler failures answer `-32603`, and error responses reject the pending request with `JsonRpcResponseError`, which preserves the wire `code` and optional `data`. `start()` attaches stream listeners and `close()` detaches them and rejects pending requests without destroying the streams.
+
+### The SDK methods
+
+Both wire ends share one method set: three client-to-server requests and four server-to-client notifications.
+
+| Direction | Method | Payload types |
 |---|---|---|
 | client→server | `initialize` | `InitializeParams` → `InitializeResult` |
 | client→server | `session/prompt` | `SessionPromptParams` → `SessionPromptResult` (durable enqueue receipt) |

-`HarnessSdkRequestMap` and `HarnessSdkNotificationMap` index these by method name. `SessionPromptResult.messageId` identifies the queued `UserMessage`; it does not identify a later assistant message, turn ending, or prompt result. `SdkPromptContentBlock` admits ordinary durable content plus `SdkEncodedImageBlock { type: "image", data, mimeType }`; the server converts encoded images to durable references before enqueue. Clients combine the open-ended `session.event` stream with agent-wide `session.status` according to their own activity ownership. `SubagentFinishedNotification.lastAssistantMessage` contains the child's last non-empty assistant message or, when no such message exists, its accumulated assistant text; the field is absent when the child produced neither. `InitializeParams.reasoningEffort` is an optional non-empty adapter-owned identifier for the selected provider/model route; omission preserves that model's own default. `InitializeParams.maxTokens` is an optional positive safe integer that caps each conversation-model output for SDK-created agents and their in-process descendants; omission allows the selected adapter's exact-model default to apply, or otherwise preserves provider behavior. The server resolves the exact route during initialization and rejects `session/prompt` until that handshake succeeds, so a missing adapter, unavailable model, or unsupported effort cannot fall back to a prompt on constructor defaults.

+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design behind the wire library; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The package is built on one separation: a single newline-delimited transport class shared by both wire ends, and named types that index the protocol methods. The package root is the only import surface — source modules are not exported as deep imports. It is a pure library with no plugin, config, or registration; the serving plugin and the clients own all behavior around it.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/transport.ts`](src/transport.ts) | `JsonRpcLineTransport`: line framing, request/response/notification dispatch, error mapping, pending-request bookkeeping |
+| [`src/types.ts`](src/types.ts) | Named request/result and notification payload types, indexed by method |
+| [`src/index.ts`](src/index.ts) | Consumer interface: the transport and the named wire types |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant — a pure wire library owns no event stream) |
+
+### Frame dispatch
+
+Incoming lines are parsed one at a time: a frame with `id` and `method` is answered through the request handler (or `-32601`), a frame with `id` alone resolves the matching pending request (an error frame rejects it with `JsonRpcResponseError`), and a frame with `method` alone is handed to the notification handler. `start()` attaches the input listeners; `close()` detaches them and fails every pending request without destroying the streams.

-`JsonRpcLineTransport` 在调用方持有的字节流上为 JSON-RPC 2.0 分帧，每行一个紧凑 JSON 帧、以 `\n` 结尾。带 `id` 与 `method` 的帧是请求，仅 `id` 是响应，仅 `method` 是通知；非法 JSON 行被忽略。`start()` 挂接流监听器，`close()` 移除监听器并拒绝挂起请求，但不销毁流。缺失请求处理器时应答 `-32601`；处理器返回的 Promise 被拒绝时，则应答携带错误消息的 `-32603`。错误响应会以 `JsonRpcResponseError` 拒绝挂起的 `request()` Promise，并保留协议格式中的 `code` 与可选 `data`。`JsonRpcTransportPeer` 是服务器类据以进行类型声明的出站接口（request/notify）。

+
+本包建立在一个分离之上：两个协议端共用一个按换行分帧的传输类，以及按方法索引协议类型的具名类型。包根是唯一的导入面——源模块不支持深层导入。它是没有插件、配置或注册的纯库；服务插件与客户端负责其周围的一切行为。

 English | [中文](README.zh.md)
 
-The `jsonrpc` plugin serves newline-delimited JSON-RPC over stdio so out-of-process SDK clients can drive harness agents. [`HarnessSdkJsonRpcServer`](src/server.ts) owns the protocol methods and notifications; the transport and the named wire types live in [`dsh-sdk-protocol`](../protocol/README.md), shared with the client SDKs. TypeScript and Python clients receive this server through `dsh --profile sdk` or another profile that mounts the same row.
+## Summary
 
-## Wiring
+`dsh-sdk-jsonrpc-server` serves the SDK wire protocol over stdio so out-of-process clients can drive harness agents: it opens one session per `sessionId`, queues user prompts, and streams every session event and agent status transition back to the client. Mount it as the `jsonrpc` plugin in a Loader composition; the surrounding tree supplies everything else — agents, model adapters, persistence, and tools. Stdout carries only JSON-RPC frames, so a deployment must not compose a stdout logger. It answers `shutdown` by disposing the root runtime and exiting 0; the app bin owns EOF and signal exits.
 
-`inject: ['agents']`. The server gets or creates one agent per `sessionId`. It forwards subagent completions only when the service-snapshotted lifecycle `local` flag is true; provider names, child ids, and durable lineage never establish locality. A registered adapter wins, an unowned `deepseek-official` route mounts `dsh-llm-deepseek`, and any other unowned provider fails initialization. The selected adapter resolves the exact model and optional reasoning effort before initialization succeeds. Other capabilities come from the surrounding Loader composition.

-`maxTokensAsSuccess` defaults to `false` and affects only the deployment-mapped status on `subagent.finished`; root-session prompts have no prompt-level status. The profile composition owns each root agent's tools. `JsonRpcConfig.input`, `output`, and `exit` are runtime-only transport hooks; production uses process stdio and `process.exit`.

+Mount this plugin when a runtime must serve SDK clients: add it to a `cordis.yml` that composes the agent service, boot the runtime, and clients connect over stdio. The common path is explicit — the plugin needs the `agents` service; every other capability comes from the surrounding tree.
 
-## Shutdown and exit semantics
+### Wiring
 
-The plugin answers `shutdown`, flushes the response, disposes the root context so SDK-owned agents, subscriptions, and persistence reach quiescence, then exits with code 0. EOF and signal exits belong to the app bin, which also disposes the root context. Unloading only this plugin stops serving without exiting the process.
+The plugin creates one agent per `sessionId` on first use. A registered model adapter wins the route; an unowned `deepseek-official` route mounts the DeepSeek adapter, and any other unowned provider fails initialization. The selected adapter resolves the exact model and optional reasoning effort before initialization succeeds.
 
-## Wire notes
+### Configuration
 
-`initialize` is the runtime-readiness boundary: when the server is mounted by a Loader composition, it waits for the current plugin tree to settle before replying, so async sibling capabilities such as initial MCP tool discovery are visible to the first prompt. Hand-built contexts without Loader remain immediately usable. `initialize.serverInfo.name` is the wire-stable `deepseek-harness-sdk-runtime`. The server validates the provider/model route and optional non-empty `reasoningEffort` through the selected adapter before storing them; omission stores no effort, so the model retains its own default. An optional positive `initialize.maxTokens` becomes the request output cap of each SDK-created agent and its in-process descendants; invalid values reject initialization, while omission sends no SDK cap and allows the selected adapter or provider route default to apply. JSON-RPC requests may dispatch concurrently, so `session/prompt` rejects until one `initialize` has completed successfully; clients must await the handshake before sending prompts. An accepted prompt queues one identified user message and immediately returns `{ messageId }`. The server streams every durable fact as `session.event` and every whole-agent lifecycle transition as `session.status`; it does not assign an assistant message or `turn/end` to that prompt. Independent requests may enqueue more work on the same session. Persistence roots and persona come from the surrounding composition.
+| Field | Default | Meaning |
+|---|---|---|
+| `maxTokensAsSuccess` | `false` | Report max-token turn/subagent termination as a successful SDK result |
 
+The profile composition owns each root agent's tools. `input`, `output`, and `exit` are runtime-only transport hooks for tests; production uses process stdio and `process.exit`. The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-sdk-jsonrpc-server) is the exhaustive source for every accepted field.

+Stdout carries only JSON-RPC frames, so clients can parse every byte; diagnostics belong on stderr. Keep stdout loggers out of the composed tree.
+
+### What SDK clients can do
+
+`initialize` is the runtime-readiness boundary: when the server is mounted by a Loader composition, it waits for the current plugin tree to settle before replying, so async sibling capabilities such as initial MCP tool discovery are visible to the first prompt. The handshake returns the wire-stable identity `deepseek-harness-sdk-runtime`. The server validates the provider/model route and optional non-empty `reasoningEffort` through the selected adapter before it stores them; omission stores no effort, so the model retains its own default. An optional positive `maxTokens` becomes the request output cap of each SDK-created agent and its in-process descendants, while omission applies the selected adapter or provider route default.

+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design behind the serving plugin; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The plugin is a thin presentation adapter: [`HarnessSdkJsonRpcServer`](src/server.ts) owns the protocol methods and notifications, while the transport and the named wire types come from `dsh-sdk-protocol`, shared with the client SDKs. It subscribes to session, agent, and subagent lifecycle events and forwards them as wire notifications; subagent completions are forwarded only when the service-snapshotted lifecycle `local` flag is true — provider names, child ids, and durable lineage never establish locality.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `Config` schema, stdio wiring, request dispatch, shared shutdown/exit task |
+| [`src/server.ts`](src/server.ts) | `HarnessSdkJsonRpcServer`: protocol methods, per-session agent creation, lifecycle subscriptions, teardown |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant — boundary and replay tests cover the protocol mapping) |
+
+### Request flow
+
+Each protocol method validates its inputs and resolves the owning state before acting — `initialize` stores the SDK route, `session/prompt` resolves the live agent+session pair and queues the message, and `shutdown` disposes server-owned state to quiescence before flushing the response and exiting 0 — and a shared exit task guarantees that racing `shutdown` requests never dispose or exit twice. The dispatch lives in [src/index.ts](src/index.ts) and [src/server.ts](src/server.ts).
+
+### Teardown
+
+`server.shutdown()` disposes only what the server owns — the surrounding context stays running when just this plugin is unloaded. Protocol `shutdown` instead disposes the root fiber so persistence and the whole runtime reach quiescence before the process exits.

-`jsonrpc` 插件通过 stdio 提供以换行符分隔的 JSON-RPC，使进程外 SDK 客户端能够驱动 harness agent（智能体）。[`HarnessSdkJsonRpcServer`](src/server.ts) 负责协议方法和通知；传输与具名协议类型位于 [`dsh-sdk-protocol`](../protocol/README.zh.md)，与客户端 SDK 共享。TypeScript 与 Python 客户端都通过 `dsh --profile sdk` 或挂载同一配置项的其他 profile 获得该服务器。
+## 概述
 
-## 组装
+`dsh-sdk-jsonrpc-server` 通过 stdio 服务 SDK 协议格式，使进程外客户端能够驱动 harness agent（智能体）：它为每个 `sessionId` 打开一个会话、把用户提示词排入队列，并把每个会话事件与 agent 状态转换实时流回客户端。把它作为 `jsonrpc` 插件挂载到 Loader 组合中；外围插件树提供其余一切——agent、模型适配器、持久化与工具。Stdout 只承载 JSON-RPC 帧，因此部署不得组合 stdout logger。它通过 dispose（资源释放）根运行时并以 0 退出应答 `shutdown`；EOF 与信号退出归 app bin 负责。
 
-`inject: ['agents']`。服务器按 `sessionId` 获取或创建一个 agent。只有服务对生命周期建立快照时记录的 `local` 标志为 true，服务器才会转发 subagent 完成事件；提供方名称、子级 id 和持久化谱系均不能证明本地性。已注册的适配器优先；尚无适配器负责的 `deepseek-official` 路由会挂载 `dsh-llm-deepseek`，任何其他尚无适配器负责的提供方都会导致初始化失败。初始化成功前，所选适配器会解析确切模型与可选推理强度。其他能力由外围 Loader 组合提供。

-插件响应 `shutdown`，刷新响应并 dispose（资源释放）根上下文，使 SDK 持有的 agent、订阅和持久化达到完全停稳，然后以代码 0 退出。EOF 和信号退出由 app bin 处理，后者也会 dispose 根上下文。仅卸载此插件会停止服务，但不会退出进程。
+插件在首次使用时为每个 `sessionId` 创建一个 agent。已注册的模型适配器赢得路由；尚无适配器负责的 `deepseek-official` 路由会挂载 DeepSeek 适配器，任何其他尚无适配器负责的提供方都会导致初始化失败。初始化成功前，所选适配器会解析确切模型与可选推理强度。

-`initialize` 是运行时就绪边界：服务器由 Loader 组合挂载时，会等待当前插件树完成所有加载任务后再响应，因此首次提示词能够看到 MCP 初始工具发现等异步同级能力。没有 Loader 的手工组装上下文仍可立即使用。`initialize.serverInfo.name` 的协议稳定值为 `deepseek-harness-sdk-runtime`。服务器会通过所选适配器校验提供方／模型路由与可选的非空 `reasoningEffort`，再保存这些值；省略时不会保存推理强度，因此模型保留自身默认值。可选的正整数 `initialize.maxTokens` 会成为每个 SDK 创建的 agent 及其进程内后代的请求输出上限；非法值会使初始化失败，省略时则不发送 SDK 上限，并应用所选适配器或提供方路由的默认值。JSON-RPC 请求可能并发分派，因此在一次 `initialize` 成功完成之前，`session/prompt` 会拒绝；客户端必须等待握手完成后再发送提示词。已接受的提示词会把一条带标识的用户消息排入队列，并立即返回 `{ messageId }`。服务器将每个持久事实作为 `session.event` 流式发出，并将整个 agent 生命周期的每次状态转换作为 `session.status` 发出；它不会把某条助手消息或 `turn/end` 归属于该提示词。同一会话上的独立请求可以继续排入更多工作。持久化根目录和 persona 由外围组合提供。

+
+本节解释服务插件背后的设计；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+本插件是薄薄的展示适配器：[`HarnessSdkJsonRpcServer`](src/server.ts) 负责协议方法与通知，传输与具名协议类型来自 `dsh-sdk-protocol`，与客户端 SDK 共享。它订阅会话、agent 与 subagent 生命周期事件，并把它们作为协议通知转发；只有当服务在生命周期建立快照时记录的 `local` 标志为 true 时才转发 subagent 完成事件——提供方名称、子级 id 与持久化谱系均不能证明本地性。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：`Config` schema、stdio 接线、请求分发、共享关闭/退出任务 |
+| [`src/server.ts`](src/server.ts) | `HarnessSdkJsonRpcServer`：协议方法、逐会话 agent 创建、生命周期订阅、清理 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式配套插件（无运行时不变式——边界与回放测试覆盖协议映射） |
+
+### 请求流程
+
+每个协议方法在行动前都会校验输入并解析其拥有的状态——`initialize` 保存 SDK 路由，`session/prompt` 解析存活的 agent+会话对并排入消息，`shutdown` 在刷新响应并以 0 退出前把服务器持有的状态 dispose 到完全停稳——共享退出任务确保竞争的 shutdown 请求绝不会重复 dispose 或退出。分发逻辑位于 [src/index.ts](src/index.ts) 与 [src/server.ts](src/server.ts)。
+
+### 清理
+
+`server.shutdown()` 只 dispose 服务器自身持有的内容——仅卸载本插件时，外围上下文保持运行。协议 `shutdown` 则 dispose 根 fiber，使持久化与整个运行时在进程退出前达到完全停稳。

-#### 模型看到的内容
+#### 模型看到什么
 
 对于每个已接受的 `session/prompt`，文本和持久内容引用会原样进入一条用户消息。内联 `SdkEncodedImageBlock` 会先通过组合中的附件存储完成校验与提交，因此会话日志保留内容寻址的图片引用而不是 base64 字节。此包不会添加系统提示词文本或工具 schema；这些内容来自组合中的其他插件。
 
 #### Token 影响
 
-依数据而定的用户消息 token 会进入保留的会话历史，并在后续轮次中重复发送，直至另一个包将其压缩（compaction）。JSON-RPC 帧、会话通知和服务器内部记录不会增加模型上下文 token。

 # session-query/ — session retrieval capability family
 
 English | [中文](README.zh.md)
 
-This family provides authorized retrieval over live and durable session logs, independently of compaction.
+## Summary
+
+The `session-query/` group provides retrieval over live and durable session history, independent of compaction: programmatic callers query one unified service for exact logs, filtered lists, relationship traces, and full-text search; a SQLite backend powers the search; the model gets five workspace-authorized tools; and the Web UI gets an `/export` command that downloads a session ZIP. Search results agree with the conversation history the model sees. This page maps the group; each package README owns its per-package contract.

 # @deepseek-ai/dsh-session-log-export
 
 English | [中文](README.zh.md)
 
-Web Session-log download control over the host-streamed ZIP endpoint owned by `dsh-host-apiproxy`. The Host half registers `/export`; the browser half owns a 111×32 `Session log` action in the Session Header, one download controller, and one modal shared by that button and the slash command. ZIP generation, raw JSONL/zstd reads, descendants, attachments, backpressure, and HTTP error semantics remain owned by the [ApiProxy download implementation](../../host/apiproxy/README.md).
+## Summary
 
-## Command contract
+`dsh-session-log-export` gives the Web interface a way to download a session's full history: a `Session log` button in the Session Header and an `/export` slash command both hand the session tree — the session, its sub-sessions, and attachments — to the browser as a ZIP download. A small dialog reports preparation, download start, or failure, shared by the button and the command. The ZIP is built and streamed by `dsh-host-apiproxy`; this package adds only the browser-side button and command. The download is a browser download: the browser chooses the destination. Setup and usage come first; the implementation internals live in a collapsible developer section below.
 
-| Input | Result |
-|---|---|
-| `/export` | Record a human-command lifecycle; the submitting browser receives the local execution acknowledgment and downloads `GET /api/session.export?sessionId=<id>&includeDescendants=true`. |
-| `/export <path>` | Return an error. Browser downloads choose their destination through the browser's ordinary download behavior. |
+## Table of Contents
 
-The command is mounted only by the Web bundle. The local `command/executed` acknowledgment triggers the slash download only after a successful `/export` result in the browser that submitted it; other tabs still render the durable command row without repeating the browser side effect. The Header button calls the same controller directly. Both entry paths issue a `HEAD` preflight, then hand the GET URL to the browser download manager without buffering the ZIP in JavaScript; they share in-flight collapsing, cancellation of the preflight on plugin disposal, preparation-error handling, browser save behavior, and the same Modal.

+- [Further Exploration](#further-exploration)

+- [Known Limitations and Deferred Work](#known-limitations-and-deferred-work)

-The Host download endpoint flushes a live root Session before `readRaw`, so a slash-triggered ZIP includes the `command/run` and `command/done` pair whose acknowledgment started the download. Cold persisted Sessions require no flush.
+-----
 
-The modal reports preparation, download start, or failure. Closing it does not cancel an in-flight download and does not reopen it when that operation later settles. One Session admits one active download at a time; repeated gestures share that operation.
+<a id="use-this-package"></a>
+## Use this package
 
-## Composition
+Use this package when the Web bundle should let users export a session log. It is mounted only by the Web bundle, beside the host API proxy, the command registry, and the conversation UI. The common path is: mount the plugin, then click `Session log` in the Session Header or type `/export` — the browser downloads `dsh-session-<id>.zip`.
+
+### When to choose it
+
+Choose it for a Web deployment that needs user-facing session export with a visible download dialog. Avoid it when a programmatic or Host-side export is needed: this package produces a browser download, not a Host path write, and it requires a persistence backend that stores a per-session raw artifact (the shipped JSONL backend supports plaintext and zstd; SQLite export is not supported).
+
+### Composition
 
 ```yaml
 - id: session-log-download
   name: '@deepseek-ai/dsh-session-log-export'
 ```
 
-The Web bundle mounts the package beside `dsh-host-apiproxy`, `dsh-commands`, `dsh-client-ui-commands`, and `dsh-client-ui-conversation`. The package contributes its button and modal to the right-aligned `conversation.session.header.utilities` list, independently of the title-adjacent mode, Subagent, and Task entries in `conversation.session.header.actions`; Trajectory carries no export control.
+The Web bundle mounts the package beside `dsh-host-apiproxy`, `dsh-commands`, `dsh-client-ui-commands`, and `dsh-client-ui-conversation`.
 
+### Command contract
+
+| Input | Result |
+|---|---|
+| `/export` | Records a human-command lifecycle; the submitting browser downloads `GET /api/session.export?sessionId=<id>&includeDescendants=true` |
+| `/export <path>` | An error; browser downloads choose their destination through the browser's ordinary download behavior |
+
+### What to expect
+
+The dialog reports three phases: preparing, download started, or failed. Closing the dialog does not cancel an in-flight download, and the dialog does not reopen when that operation later settles. One session admits one active download at a time; repeated gestures share that operation. The export includes the live session's newest events: the host endpoint flushes a live root session before reading, so a slash-triggered ZIP includes the `command/run` and `command/done` pair that started the download; cold persisted sessions need no flush.
+
+### Failures
+
+The dialog shows a preparation error when the preflight fails before ZIP streaming starts — for example an unreachable or misconfigured host endpoint. A descendant or attachment read failure after the browser accepts the GET is reported by the browser download manager, not by the dialog.

+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the package wires the export control and points at the code that realizes it; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design split
+
+The package has two halves. The host half ([`src/index.ts`](src/index.ts)) registers the `/export` command on `ctx.commands`; the browser half ([`src/client/index.ts`](src/client/index.ts)) provides a `SessionLogDownloadController`, contributes the Header button and shared modal to the `conversation.session.header.utilities` slot, and observes `command/executed` so a successful `/export` in the submitting browser starts the same download. Other tabs still render the durable command row without repeating the browser side effect.
+
+### Download flow
+
+Both entry paths issue a `HEAD` preflight to `GET /api/session.export?...`, then hand the GET URL to the browser download manager without buffering the ZIP in JavaScript. One controller owns one in-flight download per session, collapses concurrent gestures into that operation, and cancels the preflight on plugin disposal. Modal state lives in a snapshot store keyed by session, so the button and the command share one dialog per session.
+
+The host download endpoint is owned by [`dsh-host-apiproxy`](../../host/apiproxy/README.md): it flushes a live root session before `readRaw` and streams the ZIP; ZIP generation, raw JSONL/zstd reads, descendants, attachments, backpressure, and HTTP error semantics belong there.

 # @deepseek-ai/dsh-session-log-export
 
 [English](README.md) | 中文
 
-Web Session 日志下载控制，使用 `dsh-host-apiproxy` 拥有的 Host 流式 ZIP 端点。Host 半包注册 `/export`；浏览器半包在 Session Header 中提供 111×32 的 `Session log` 操作，以及一个供该按钮与斜杠命令共用的下载控制器和弹窗。ZIP 生成、原始 JSONL/zstd 读取、子 Session、附件、背压和 HTTP 错误语义仍由 [ApiProxy 下载实现](../../host/apiproxy/README.zh.md)负责。
+## 概述
 
-## 命令约定
+`dsh-session-log-export` 让 Web 界面可以下载会话的完整历史：Session Header 中的 `Session log` 按钮与 `/export` 斜杠命令都会把会话树——会话本身、其子会话与附件——作为 ZIP 交给浏览器下载。一个小弹窗报告准备中、开始下载或失败，按钮与命令共用该弹窗。ZIP 由 `dsh-host-apiproxy` 生成并流式传输；本包只提供浏览器侧的按钮与命令。下载是浏览器下载：目标位置由浏览器选择。设置与用法在前；实现内部细节放在下方可折叠的开发者章节中。
 
-| 输入 | 结果 |
-|---|---|
-| `/export` | 记录一组用户命令生命周期；提交命令的浏览器收到本地执行确认后，下载 `GET /api/session.export?sessionId=<id>&includeDescendants=true`。 |
-| `/export <path>` | 返回错误。浏览器下载通过浏览器的普通下载行为选择目标位置。 |
+## 目录
 
-该命令只由 Web bundle 挂载。只有 `/export` 返回成功时，本地 `command/executed` 确认才会在提交命令的浏览器中触发斜杠下载；其他标签页仍会渲染持久命令行，但不会重复执行浏览器副作用。Header 按钮直接调用同一个控制器。两种入口都会先发出 `HEAD` 预检，再把 GET URL 交给浏览器下载管理器，JavaScript 不会缓冲 ZIP；它们共用并发折叠、插件释放时取消预检、准备阶段错误处理、浏览器保存行为和同一个 Modal。

-Host 下载端点会在 `readRaw` 前 flush 活动的根 Session，因此斜杠命令触发的 ZIP 会包含启动下载的 `command/run` 与 `command/done` 事件对。冷持久化 Session 不需要 flush。
+-----
 
-弹窗报告准备中、开始下载或失败。关闭弹窗不会取消正在进行的下载；该操作随后完成时也不会重新打开弹窗。每个 Session 同时只允许一项下载，重复操作会共用该任务。
+<a id="use-this-package"></a>
+## 使用本包
 
-## 组合
+当 Web bundle 需要让用户导出会话日志时使用本包。它只由 Web bundle 挂载，与 Host API 代理、命令注册表和对话 UI 并列。常用路径是：挂载插件，然后点击 Session Header 中的 `Session log` 或输入 `/export`——浏览器下载 `dsh-session-<id>.zip`。
+
+### 何时选择
+
+为需要带可见下载弹窗的用户级会话导出的 Web 部署选择它。需要程序化或 Host 侧导出时避免使用：本包产生的是浏览器下载，而非 Host 路径写入，并且它要求持久化后端保存逐会话原始产物（随附 JSONL 后端支持明文与 zstd；不支持 SQLite 导出）。
+
+### 组合
 
 ```yaml
 - id: session-log-download
   name: '@deepseek-ai/dsh-session-log-export'
 ```
 
-Web bundle 将本包与 `dsh-host-apiproxy`、`dsh-commands`、`dsh-client-ui-commands` 和 `dsh-client-ui-conversation` 一起挂载。本包把按钮和弹窗贡献到最右侧的 `conversation.session.header.utilities` 列表，与标题旁 `conversation.session.header.actions` 中的模式、Subagent 和 Task 配置项相互独立；Trajectory 不包含导出入口。

+
+两条入口都会对 `GET /api/session.export?...` 发出 `HEAD` 预检，然后把 GET URL 交给浏览器下载管理器，JavaScript 不缓冲 ZIP。一个控制器按会话持有一项进行中的下载，把并发操作折叠进该任务，并在插件释放时取消预检。弹窗状态存放在按会话键控的快照存储中，因此按钮与命令按会话共享一个弹窗。

 # @deepseek-ai/dsh-session-query-sqlite
 
 English | [中文](README.zh.md)
 
-Concrete `ctx.sessionQuery` provider. `SqliteSessionQueryEngine` inherits exact reads, traces, and provider-independent filters from the Service Definition package and implements its two full-text methods with SQLite FTS5. Search uses the live-preferred logical session corpus and groups cross-session results by their strongest event.
+## Summary
 
-## Search contract
+`dsh-session-query-sqlite` searches session history with a SQLite FTS5 index and returns ranked, cursor-paginated results grouped by session or within one session. Mount it together with `dsh-session-query` and you get full-text search plus the whole query surface — exact reads, filters, and traces — at once. Live sessions are indexed from memory and persisted sessions from a dedicated derived-index database, so results always reflect the newest state without touching the session-persistence store. Search is opt-in and off by default in shipped compositions: `openAt` decides whether the index opens at startup, at the first search, or never. Setup and usage come first; the implementation internals live in a collapsible developer section below.
 
-`searchSessions(request, exec?)` returns `SessionSearchHit` pages across the corpus; `searchEvents(request, exec?)` returns `SessionEventSearchHit` pages within one session. Queries are required, trimmed, whitespace-normalized literal phrases. FTS5 syntax such as quotes, `OR`, `NEAR`, and `*` is treated as data rather than executable MATCH syntax. Metadata filters are parameterized SQL predicates applied before ranking. To keep SQLite FTS5 MATCH in a supported outer-predicate context, cross-session requests may compile at most 14 combined session and event filter predicates; within-session requests may compile at most 13 filter predicates because the fixed target-session predicate consumes one slot. Each range endpoint compiles as one predicate. A request exceeding either predicate budget or SQLite's portable limit of 32,766 total bindings, including fixed query and pagination values, fails with `SESSION_QUERY_INVALID_FILTER` before statement preparation.
+## Table of Contents
 
-Relevance is source-comparable across persistent and TEMP tables: actual FTS5 highlighted-match span count descending, then stored document code-point length ascending. Event time, session id where applicable, and seq break remaining ties. Cross-session results expose the selected event as `bestMatch`; both scopes derive whitespace-normalized plain text from FTS5 highlight positions and bound it in Unicode code points. Cursors are opaque branded values, bind to the normalized request and service instance, and fail when the relevant generation changes. A within-session cursor survives unrelated-session changes; a cross-session cursor does not.

-## Source and index lifecycle
+<a id="use-this-package"></a>
+## Use this package
 
-The service requires `ctx.sessions` and observes optional `ctx.sessionPersistence` dynamically. One serialized state machine compares source-qualified lightweight durable snapshot revisions, non-mutatingly inspects only new or changed logs, extracts shared semantic documents, reconciles changes transactionally, and runs the query. Session queries never invoke the persistence backend's crash-repairing `load()`; an owner attaching during inspection cannot mutate its log, and the stable-observation retry makes the result live-preferred. The TEMP live row still records persisted availability, and the durable base refreshes after that live owner detaches. Repeated queries and an unchanged same-store reopen perform no full durable-log inspection; switching stores, or observing new, changed, deleted, or externally load-repaired sources, reconciles on the next stable observation. Source or transaction failure commits nothing, and the next search retries.
+Mount this package when a composition needs ranked full-text search over session history — for example the Web content search or `/resume` prior-work retrieval. The common path is explicit: mount the plugin, give it a dedicated database path, and call `ctx.sessionQuery.searchSessions` or `searchEvents` from code.
 
-`openAt: startup` is the default: service activation imports `node:sqlite`, opens the handle, and fails before publication when the index is invalid. `openAt: first-search` publishes the service as ACTIVE without importing the SQLite module or opening a handle; the first concurrent searches share one readiness promise, and disposal before any search opens nothing. This mode supports compositions that need clean Node 22 startup output by deferring SQLite's experimental warning until the first actual search; it does not suppress a warning at that point. An invalid database likewise fails the first search instead of service activation. `openAt: never` turns full-text search off for the deployment: `searchSessions` and `searchEvents` fail with `SESSION_QUERY_SEARCH_DISABLED` before any request normalization, node:sqlite is never imported or opened, and no source observation or reconciliation runs, while every inherited exact read, filter, and trace on `ctx.sessionQuery` keeps working.
+### When to choose it
 
-Persisted FTS rows live in a dedicated derived database. Connection-local TEMP tables hold live rows, which shadow the durable base for the same session and reveal it when the live owner disappears. Unmounting persistence hides durable rows without discarding the cache; remounting reconciles it. Closing or reopening the database drops every live overlay while retaining persisted rows.
+Choose it when you want full-text recall over prior sessions with ranking and paging. Choose it together with `dsh-session-query` and the session service; a persistence backend is optional but recommended so persisted history is searchable after restarts. Avoid pointing `path` at the session-persistence database — this package owns a separate derived index.
 
-The database is disposable but reset is guarded: every recognized schema version rejects unknown user tables before mutating journal mode, and only a recognized incompatible schema containing derived tables rebuilds in place. An unrelated or canonical database is refused. Never point `path` at the session-persistence database. On filesystems with POSIX modes, missing directories and databases are created owner-only (`0700` and `0600` before the process umask), and SQLite sidecars inherit the database mode; existing modes are preserved. Exactly one service in one process owns a derived-index path; external writers or a second process are unsupported because generations and TEMP shadow state are connection-owned.

-## Tokenizer and limits
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-session-query-sqlite) is the exhaustive source for every accepted field and its JSDoc.
 
-The index uses FTS5 `unicode61`. The trade-off is token/phrase recall rather than arbitrary substring recall: `AI` does not match the token `BRAID`. Use `ctx.sessionQuery.filterEvents()` with a `text` clause when a literal whitespace-flexible substring scan is required. NUL is rejected in queries; reserved highlight markers and NUL in documents are normalized before indexing so presentation markers cannot collide with source text.
+### Search behavior
 
-Abort signals stop queued work and flow unchanged through snapshot listing and non-mutating inspection. Once source work starts, the serialized state machine awaits that backend promise itself—even when a backend ignores cancellation—then checks the signal before starting any further listing, inspection, reconciliation, or query work. The caller therefore observes cancellation only after started backend work is quiescent, and a later search cannot enter the serializer while that cleanup is pending. Node's synchronous `DatabaseSync` API cannot interrupt a metadata or MATCH statement already executing on the JavaScript thread; signals are checked immediately before and after those non-preemptible calls.
+`searchSessions` searches the whole corpus and groups results by each session's strongest matching event; `searchEvents` searches one logical session. Queries are literal phrases: they are trimmed and whitespace-normalized, and FTS5 syntax such as quotes, `OR`, `NEAR`, and `*` is treated as data, never as executable query syntax. Metadata filters (session id, cwd, created-at, parent, availability, event seq/time/type/surface) narrow results before ranking. All `current`, `shadowed`, and `log-only` events are searchable by default; pass a surface filter to narrow.
 
+Ranking is deterministic: more actual FTS5 highlighted-match spans first, then shorter documents, with event time, session id, and seq breaking ties. Results carry plain-text snippets bounded by `snippetChars` Unicode code points, with no provider-specific numeric score. Pages continue through an opaque `SessionSearchCursor` bound to the exact normalized request; a cursor becomes stale when its relevant corpus changes (`SESSION_QUERY_STALE_CURSOR`), and a within-session cursor survives changes to unrelated sessions while a cross-session cursor does not.
+
+The `unicode61` tokenizer matches tokens and phrases, not arbitrary substrings: `AI` does not match the token `BRAID`. Use `ctx.sessionQuery.filterEvents()` with a `text` clause when a literal whitespace-flexible substring scan is required.
+
+### When to defer or disable search
+
+With `openAt: first-search`, the service activates without importing `node:sqlite` or opening the index, deferring SQLite's experimental warning until the first actual search; an invalid database fails that first search instead of service activation. With `openAt: never`, full-text search is off for the deployment: `searchSessions` and `searchEvents` fail with `SESSION_QUERY_SEARCH_DISABLED` before any request normalization, while every inherited exact read, filter, and trace keeps working. Requests that exceed the compiled-predicate budget (14 combined predicates across sessions, 13 within a session) or SQLite's portable 32,766-binding limit fail with `SESSION_QUERY_INVALID_FILTER` before statement preparation.
+
+### Failures and recovery
+
+Typed `SessionQueryError` failures carry stable codes: `SESSION_QUERY_SEARCH_DISABLED` when search is configured off; `SESSION_QUERY_INDEX_FAILED` when the index cannot open or reconcile; `SESSION_QUERY_SESSION_NOT_FOUND` when a search target is absent; `SESSION_QUERY_STALE_CURSOR` when the corpus changed between pages — retry the complete search call; and `SESSION_QUERY_INVALID_CURSOR` for a cursor that does not belong to this request. Cancellation is honored between synchronous SQLite calls; a statement already executing on the JavaScript thread cannot be interrupted.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the backend and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The backend is built on one separation and three commitments:
+
+- **Derived index, never the source store.** The FTS rows live in a dedicated disposable database; the session-persistence database is never opened here.
+- **Live-preferred observation.** One serialized state machine compares persistence snapshot revisions, inspects only new or changed logs, and reconciles in one transaction, so a search reflects the newest stable state.
+- **Generation-bound cursors.** Every corpus change bumps a generation; cursors carry the generation they were created under and fail stale rather than returning a shifted page.
+- **Literal phrases as data.** Caller query text is quoted into one FTS5 phrase so query syntax stays inert, and reserved highlight markers are stripped from documents before indexing.
+
+The design history lives in the [SQLite FTS5 session search note](../../../.agents/notes/implemented/feature/2026-07-10-sqlite-session-query-provider.md) and the [unified service decision](../../../.agents/notes/archived/architecture/2026-07-23-unified-session-query-service.md).
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Service: config, openAt lifecycle, serialized reconciliation, query execution, cursors |
+| [`src/query.ts`](src/query.ts) | Request normalization, parameterized predicates, snippets, predicate and binding budgets |
+| [`src/schema.ts`](src/schema.ts) | Database schema, application-id ownership, in-place reset, owner-only file creation |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; boundaries are validated per serialized query) |
+
+### Index lifecycle
+
+Persisted FTS rows live in a dedicated derived database and survive restarts; live sessions use connection-local TEMP tables that shadow the durable base for the same session and reveal it again when the live owner detaches. Each search runs one serialized observation: list persistence snapshots, compare per-session revisions with the indexed rows, inspect only new or changed logs, extract semantic documents, and commit the reconciliation in one transaction before running the query. Repeated queries and unchanged reopens inspect nothing; switching stores or observing new, changed, deleted, or externally repaired sources reconciles on the next stable observation. Source or transaction failure commits nothing and the next search retries.
+
+### Schema ownership
+
+The database carries an application id and schema version 8. Opening refuses a file owned by another application or a canonical database, rejects unknown user tables, and only a recognized incompatible derived schema resets in place — so an unrelated or session-persistence database is never touched. On POSIX filesystems, missing directories and database files are created owner-only (`0700` and `0600` before the process umask). Exactly one service in one process owns a derived-index path; generations and TEMP shadow state are connection-owned.

 # @deepseek-ai/dsh-session-query-sqlite
 
 [English](README.md) | 中文
 
-具体 `ctx.sessionQuery` 提供方。`SqliteSessionQueryEngine` 从 Service Definition 包继承精确读取、跟踪和提供方无关的过滤，并使用 SQLite FTS5 实现其两个全文方法。搜索使用实时优先的逻辑会话语料库，并按每个会话中匹配度最高的事件对跨会话结果分组。
+## 概述
 
-## 搜索约定
+`dsh-session-query-sqlite` 用 SQLite FTS5 索引搜索会话历史，返回按会话分组或会话内排序、游标分页的结果。与 `dsh-session-query` 一起挂载，即可同时获得全文搜索与完整查询表面——精确读取、过滤与追踪。实时会话从内存索引，持久化会话从专用派生索引数据库索引，因此结果始终反映最新状态，且不触碰会话持久化存储。搜索是可选能力，已发布组合默认关闭：`openAt` 决定索引在启动时、首次搜索时打开，还是永不打开。设置与用法在前；实现内部细节放在下方可折叠的开发者章节中。
 
-`searchSessions(request, exec?)` 返回跨语料库的 `SessionSearchHit` 分页结果；`searchEvents(request, exec?)` 返回单个会话内的 `SessionEventSearchHit` 分页结果。查询不得省略，首尾空白会被移除，内部空白会被规范化，并按字面短语处理。引号、`OR`、`NEAR` 和 `*` 等 FTS5 语法被视为数据，而非可执行 MATCH 语法。元数据过滤器是在排名前应用的参数化 SQL 谓词。为使 SQLite FTS5 MATCH 保持在受支持的外层谓词上下文中，跨会话请求最多可编译 14 个组合会话与事件过滤谓词；会话内请求最多可编译 13 个过滤谓词，因为固定目标会话谓词占用一个 slot。每个范围端点编译为一个谓词。请求超过任一谓词预算，或超过 SQLite 可移植的 32,766 总绑定上限（包括固定查询和分页值）时，会在准备语句前以 `SESSION_QUERY_INVALID_FILTER` 失败。
+## 目录
 
-持久表和 TEMP 表之间的相关性排名可直接比较：先按实际 FTS5 高亮匹配 span 数降序，再按已存储文档码点长度升序。事件时间、适用时的会话 id 和 seq 打破其余平局。跨会话结果将所选事件公开为 `bestMatch`；两种范围都从 FTS5 高亮位置派生空白规范化的纯文本，并按 Unicode 码点限制长度。游标是带品牌类型的不透明值，绑定到规范化请求和服务实例，并在相关世代变更时失败。会话内游标可在不相关会话变更后延续使用；跨会话游标则不能。

-## 来源与索引生命周期
+<a id="use-this-package"></a>
+## 使用本包
 
-该服务需要 `ctx.sessions`，并动态观察可选的 `ctx.sessionPersistence`。一个串行化状态机比较来源限定的轻量持久化快照修订，仅以不修改日志的方式检查新日志或已更改日志，提取共享语义文档，以事务方式对账变更，然后运行查询。会话查询绝不会调用持久化后端会修复崩溃的 `load()`；检查期间接入的活动所有者无法修改其日志，稳定观察重试使结果优先使用实时来源。TEMP 实时行仍会记录持久化可用性，而持久基库会在该活动所有者脱离后刷新。重复查询以及同一存储未发生变化的重新打开操作不会执行完整持久化日志检查；切换存储，或观察到新增、已更改、已删除或经外部 load 修复的来源时，会在下次稳定观察时对账。来源或事务失败不会提交任何内容，下一次搜索会重试。
+当组合需要对会话历史进行排序后的全文搜索时——例如 Web 内容搜索或 `/resume` 既往工作检索——挂载本包。常用路径是显式的：挂载插件、给它一个专用数据库路径，然后从代码调用 `ctx.sessionQuery.searchSessions` 或 `searchEvents`。
 
-`openAt: startup` 是默认值：服务激活会导入 `node:sqlite` 并打开句柄；如果索引无效，则会在服务发布前失败。`openAt: first-search` 会将服务以 ACTIVE 状态发布，同时不导入 SQLite 模块也不打开句柄；首批并发搜索共享同一个就绪 promise，在任何搜索前 dispose（资源释放）服务时也不会导入模块或打开句柄。此模式通过把 SQLite 的实验性警告推迟到首次实际搜索，支持需要干净 Node 22 启动输出的组合；它不会抑制届时的警告。无效数据库同样会使首次搜索失败，而不是服务激活失败。`openAt: never` 为该部署关闭全文搜索：`searchSessions` 和 `searchEvents` 在任何请求规范化之前就以 `SESSION_QUERY_SEARCH_DISABLED` 失败，node:sqlite 绝不会被导入或打开，也不运行任何来源观察或对账，而 `ctx.sessionQuery` 上继承的全部精确读取、过滤和跟踪保持可用。
+### 何时选择
 
-持久化 FTS 行位于专用派生数据库中。连接本地 TEMP 表保存实时行，这些行会遮蔽同一会话的持久化基库，并在实时所有者消失后使其重新可见。卸载持久化会隐藏持久行，但不会丢弃缓存；重新挂载会对账缓存。关闭或重新打开数据库会删除全部实时覆盖层，但保留持久行。
+当你想对既往会话进行带排序与分页的全文召回时选择它。它与 `dsh-session-query` 和会话服务一起使用；持久化后端可选但建议挂载，这样重启后持久化历史仍可搜索。不要把 `path` 指向 session-persistence 数据库——本包拥有独立的派生索引。
 
-该数据库虽可丢弃重建，但 reset 操作受到保护：每个已识别 schema 版本都会在修改 journal mode 前拒绝未知用户表；只有包含派生表的已识别不兼容 schema 才会原地重建。不相关数据库或规范数据库将被拒绝。绝不能将 `path` 指向 session-persistence 数据库。在支持 POSIX 权限模式的文件系统上，缺失的目录和数据库会以仅所有者可访问的方式创建（进程 umask 前为 `0700` 和 `0600`），SQLite 伴随文件继承数据库的权限模式；现有权限模式保持不变。每个派生索引路径在一个进程中只能由一个服务拥有；不支持外部写入者或第二个进程，因为世代和 TEMP 遮蔽状态由连接持有。

-## 分词器与限制
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-session-query-sqlite)是每个受支持字段及其 JSDoc 的穷尽式真源。
 
-该索引使用 FTS5 `unicode61`。取舍是 token/短语召回而非任意子字符串召回：`AI` 不匹配 token `BRAID`。需要执行字面的空白弹性子字符串扫描时，使用 `ctx.sessionQuery.filterEvents()` 并传入 `text` 子句。查询会拒绝 NUL；文档中的保留高亮标记和 NUL 会在索引前被规范化，使展示标记无法与源文本冲突。
+### 搜索行为
 
-中止信号会停止已排队工作，并原样流经快照枚举和非修改式检查。来源工作一旦开始，串行化状态机会自行等待该后端 promise，即使后端忽略取消，之后也会在启动任何进一步的枚举、检查、对账或查询工作前检查信号。因此，调用方只会在已启动后端工作完全停稳后观察到取消，而后续搜索在该清理尚未完成时无法进入 serializer。Node 的同步 `DatabaseSync` API 无法中断已在 JavaScript 线程上执行的元数据或 MATCH 语句；系统会在这些不可抢占调用前后立即检查信号。
+`searchSessions` 搜索整个语料库，并按每个会话匹配最强的事件分组结果；`searchEvents` 搜索一个逻辑会话。查询是字面短语：首尾空白会被移除、内部空白会被规范化，引号、`OR`、`NEAR` 和 `*` 等 FTS5 语法被视为数据，绝不作为可执行查询语法。元数据过滤器（会话 id、cwd、创建时间、父级、可用性、事件 seq/时间/类型/表层）在排序前缩小结果。默认搜索全部 `current`、`shadowed` 与 `log-only` 事件；传入表层过滤器可缩小范围。
 
+排序是确定性的：实际 FTS5 高亮匹配 span 更多的在前，然后文档更短的在前，事件时间、会话 id 与 seq 打破平局。结果携带按 `snippetChars` 个 Unicode 码点截断的纯文本摘录，没有提供方专用数值分数。分页通过不透明 `SessionSearchCursor` 延续，游标绑定到规范化后的确切请求；相关语料库变化时游标变为陈旧（`SESSION_QUERY_STALE_CURSOR`），会话内游标可在不相关会话变化后延续，跨会话游标则不能。
+
+`unicode61` tokenizer 匹配 token 与短语，而非任意子字符串：`AI` 不匹配 token `BRAID`。需要执行字面、空白灵活的字符串子串扫描时，使用带 `text` 子句的 `ctx.sessionQuery.filterEvents()`。
+
+### 何时推迟或关闭搜索
+
+使用 `openAt: first-search` 时，服务在不导入 `node:sqlite`、不打开索引的情况下激活，把 SQLite 的实验性警告推迟到首次实际搜索；无效数据库让首次搜索失败，而不是服务激活失败。使用 `openAt: never` 时，全文搜索对该部署关闭：`searchSessions` 与 `searchEvents` 在任何请求规范化之前就以 `SESSION_QUERY_SEARCH_DISABLED` 失败，而继承的全部精确读取、过滤与追踪保持可用。请求超过编译谓词预算（跨会话 14 个组合谓词、会话内 13 个）或 SQLite 可移植的 32,766 绑定上限时，会在准备语句前以 `SESSION_QUERY_INVALID_FILTER` 失败。
+
+### 失败与恢复
+
+带类型的 `SessionQueryError` 失败携带稳定代码：搜索配置为关闭时 `SESSION_QUERY_SEARCH_DISABLED`；索引无法打开或对账时 `SESSION_QUERY_INDEX_FAILED`；搜索目标不存在时 `SESSION_QUERY_SESSION_NOT_FOUND`；语料库在分页之间变化时 `SESSION_QUERY_STALE_CURSOR`——请重试完整的搜索调用；游标不属于该请求时 `SESSION_QUERY_INVALID_CURSOR`。取消在同步 SQLite 调用之间被尊重；已在 JavaScript 线程上执行的语句无法被中断。

+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释后端背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+本后端建立在一个分离与三项承诺之上：
+
+- **派生索引，绝不动源存储。** FTS 行存放在专用可丢弃数据库中；这里的代码从不打开 session-persistence 数据库。
+- **实时优先的观察。** 一个串行化状态机比较持久化快照修订，只检查新增或已更改日志，并在一个事务中对账，因此搜索反映最新的稳定状态。
+- **世代绑定的游标。** 每次语料库变化都会递增世代；游标携带其创建时的世代，宁可陈旧失败也不返回偏移后的页面。
+- **字面短语即数据。** 调用方查询文本被引成一个 FTS5 短语，查询语法保持惰性；保留高亮标记在索引前从文档中剥离。
+
+设计历史记录在 [SQLite FTS5 会话搜索笔记](../../../.agents/notes/implemented/feature/2026-07-10-sqlite-session-query-provider.zh.md)与[统一服务决策](../../../.agents/notes/archived/architecture/2026-07-23-unified-session-query-service.md)中。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 服务：配置、openAt 生命周期、串行化对账、查询执行、游标 |
+| [`src/query.ts`](src/query.ts) | 请求规范化、参数化谓词、摘录、谓词与绑定预算 |
+| [`src/schema.ts`](src/schema.ts) | 数据库 schema、application id 归属、原地重置、仅所有者文件创建 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；边界在每次串行化查询时校验） |
+
+### 索引生命周期
+
+持久化 FTS 行存放在专用派生数据库中并跨重启保留；实时会话使用连接本地 TEMP 表，遮蔽同一会话的持久化基库，并在实时所有者脱离后再次显示基库。每次搜索执行一次串行化观察：列出持久化快照、把逐会话修订与已索引行比较、只检查新增或已更改日志、提取语义文档，并在运行查询前于一个事务中提交对账。重复查询与不变的重新打开不会检查任何内容；切换存储或观察到新增、已更改、已删除或经外部修复的来源时，会在下次稳定观察时对账。来源或事务失败不提交任何内容，下一次搜索重试。
+
+### Schema 归属
+
+数据库携带 application id 与 schema 版本 8。打开时拒绝其他应用程序拥有的文件或规范数据库，拒绝未知用户表；只有已识别的不兼容派生 schema 才会原地重置——因此不相关或 session-persistence 数据库绝不会被触碰。在 POSIX 文件系统上，缺失的目录与数据库文件以仅所有者可访问的方式创建（进程 umask 前为 `0700` 与 `0600`）。每个派生索引路径在一个进程中只能由一个服务拥有；世代与 TEMP 遮蔽状态由连接持有。

 # @deepseek-ai/dsh-session-query
 
 English | [中文](README.zh.md)
 
-`SessionQueryEngine` is the combined abstract `ctx.sessionQuery` contract. It implements exact session-history retrieval, relationship tracing, and provider-independent filtering over live `ctx.sessions` plus optional dynamically mounted `ctx.sessionPersistence`; concrete backends implement its two full-text methods. Matching ids produce one record: live events win, while `live` and `persisted` report both source availabilities. Conflicting immutable headers fail with `SESSION_QUERY_SOURCE_CONFLICT`.
+## Summary
 
-## Reads
+`dsh-session-query` gives code callers one service for retrieving session history: read a complete raw log, list and filter sessions, fold titles, read events with bounded context, trace session lineage and event relationships, and run full-text search. Live sessions take precedence over persisted ones, and every returned record is a detached clone, so results always describe one consistent moment. Exact reads, filters, and traces are built in; full-text search comes from a mounted backend such as `dsh-session-query-sqlite`. Use it directly from code when you need programmatic access to what the model saw. Setup and usage come first; the implementation internals live in a collapsible developer section below.
 
-- `listSessions(signal?)` reads current persistence metadata, merges live records with live precedence, and returns cloned records in deterministic newest-first order.
-- `readSession(sessionId)` returns one complete detached raw log after the same core replay validation used by resume; it never enters the session into the live store.
-- `filterSessions(filters, signal?)` applies provider-independent session metadata and availability predicates to that same cloned logical corpus.
-- `filterEvents(sessionId, filters)` extracts first-party semantic documents and applies provider-independent metadata and literal-text predicates in ascending seq order.
-- `readTitleSnapshots(sessionIds, signal?)` resolves unique ids from one live-preferred corpus observation, passes cancellation through persisted listing and inspection, and returns ordered per-session settlements so one missing or malformed title source does not discard its peers. Each live source is folded directly, and each persisted worker folds to a detached header/title result and releases the full log before dequeuing another id. Cancellation rejects the whole batch. `readTitleSnapshot(sessionId, signal?)` is the one-observation view; `readTitle(sessionId, signal?)` returns only its optional folded `session/title`.
-- `listEvents(sessionId)` loads the live-preferred raw log and classifies each event as `current`, `shadowed`, or `log-only` with the shared `dsh-session` surface fold.
-- `readSurface(sessionId)` returns one cloned header, raw-log capture boundary, and the complete folded current surface in model-history order. A live session wins over persistence; compaction is observed before or after its replacement append, never as a synthetic mixture.
-- `readEvent(request, signal?)` returns a cloned header, the full target event, and a bounded raw-seq window. `before` and `after` default to zero and may not exceed `readWindowMax`.
-- `traceSession(sessionId, signal?)` reads the corpus once and returns immediate-to-outward ancestors plus deterministic recursive descendant trees. `complete: false` identifies the first missing parent; a target-connected cycle fails with `SESSION_QUERY_INVALID_LINEAGE`.
-- `traceEvent(request, signal?)` loads the logical log once and returns its cloned source header with direct positional replacements and direct cited source-event links. `replacementChain` follows positional replacers to the final replacement; source-event links remain non-transitive.
+## Table of Contents
 
-Persistence is optional and may mount or unmount dynamically. Cross-corpus listing and lineage tracing fail with `SESSION_QUERY_PERSISTENCE_FAILED` while mounted persistence is unreadable; a successfully read durable record that fails Session validation reports `SESSION_QUERY_CORRUPT_SESSION` instead. A title read, event trace, or event read targeting a known live session does not consult persistence, so durable backend health cannot make current in-memory state unreadable. Persisted title and event operations list before loading and reject a metadata mismatch rather than combining inconsistent observations. Lineage-trace cancellation is passed to persisted listing; event-trace and event-read cancellation is passed to persisted listing and inspection. Each waits for the started backend call to settle, then rejects with the signal's exact reason even when the backend ignored that signal. A pre-aborted known-live title read, event trace, or event read rejects before folding or snapshotting without consulting persistence. A batch title observation performs one metadata listing, inspects its unique persisted ids with at most `persistedInspectConcurrency` workers, and preserves each title's own observed header for downstream authorization. Cancellation starts no queued inspections and rejects only after already-started workers settle. `listSessions()` remains lightweight and does not load logs or index titles.

-## Filtering and extraction
+-----
 
-`SessionResultFilter` covers id, nullable cwd, created-at range, nullable parent, and source availability. `SessionEventResultFilter` covers seq/time ranges, event type, surface, and semantic text. Filter arrays are ANDed; values within one list clause are ORed. Empty list values match nothing, ranges are inclusive, and malformed ranges or closed-union values fail with `SESSION_QUERY_INVALID_FILTER`.
+<a id="use-this-package"></a>
+## Use this package
 
-The text clause is deliberately independent of FTS providers: caller text is escaped into a Unicode, case-insensitive regular expression, and each whitespace run matches one or more whitespace characters. It is a literal semantic-text scan, not a full-text query. `extractSessionEventText()` and `buildSessionEventSearchDocuments()` define the shared first-party document projection; reasoning blocks, structural boundaries, stream chunks, request headers, and unknown declaration-merged variants produce no document.
+Use `ctx.sessionQuery` from application code when you need to read or search session history without touching the session service or a storage backend directly. The service is provided by a concrete backend plugin — the shipped composition mounts `@deepseek-ai/dsh-session-query-sqlite` ([README](../session-query-sqlite/README.md)) — so this package is never mounted alone. Everything below is available on `ctx.sessionQuery` once a backend is composed.
 
-## Full-text methods
+### What you can do
 
-`SessionQueryEngine.searchSessions(request, exec?)` groups the logical corpus by strongest matching event; `searchEvents(request, exec?)` searches one logical session. These are the service's only abstract methods. Both return pages whose continuation is an owned branded `SessionSearchCursor`, accept optional cancellation, and expose snippets without provider-specific numeric scores. An event-search page also carries the cloned target header from the same indexed generation as its hits, allowing authorization consumers to bind policy to the payload observation. Search requests accept only metadata event filters, because literal-text filtering is the scan path described above.
+| Operation | What you get |
+|---|---|
+| `listSessions()` | Every logical session, newest first, with `live` and `persisted` availability flags |
+| `readSession(id)` | The complete replay-validated raw event log, without making the session live |
+| `filterSessions(filters)` | Sessions matching ANDed metadata and availability predicates |
+| `filterEvents(id, filters)` | Semantic event documents matching metadata and literal-text predicates |
+| `readTitleSnapshots(ids)` | The latest folded title per session, bound to its source header |
+| `listEvents(id)` / `readSurface(id)` | Lightweight per-event records, or the complete current model surface |
+| `readEvent(request)` | One full event plus a bounded raw-log window around it |
+| `traceSession(id)` | The known ancestor chain and recursive descendant trees |
+| `traceEvent(request)` | One event's positional replacements and cited source-event relationships |
+| `searchSessions(request)` / `searchEvents(request)` | Full-text search pages, implemented by the mounted backend |
 
-The package has no provider coordinator, fallback implementation, or standalone concrete plugin. A concrete service backend inherits the implemented reads, filters, and traces while owning full-text observation, reconciliation, ranking, cursor generations, and query execution; the first implementation is [`@deepseek-ai/dsh-session-query-sqlite`](../session-query-sqlite/README.md).
+### Filters
 
-`SessionQueryError.code` is a closed union covering request validation, missing targets, malformed surfaces, source conflicts, persistence/index failures, cancellation, and invalid or stale cursors; the exact literals are defined in [`src/config.ts`](src/config.ts).
+`SessionResultFilter` narrows sessions by id, nullable cwd, created-at range, nullable parent, or source availability; `SessionEventResultFilter` narrows events by seq/time range, event type, surface, or literal text. Filter arrays are ANDed and list values within one clause are ORed; empty list values match nothing, ranges are inclusive, and malformed ranges or unknown closed-union values fail with `SESSION_QUERY_INVALID_FILTER`.
 
-`listEvents()`, `readSurface()`, and `traceEvent()` run the same one-pass `dsh-session` surface fold. A loaded log is valid only when event seqs are zero-based and contiguous, surface markers obey event-type eligibility, source-event arrays are nonempty and duplicate-free, references name earlier events, and each positional replacement names and cites every surface node it removes; every violation fails with `SESSION_QUERY_INVALID_SURFACE`.
+The text clause is a literal, case-insensitive, whitespace-flexible scan of extracted semantic text — not a full-text query. Use it for arbitrary substring recall; use the mounted backend's search methods when you need ranked full-text results.
 
-## Configuration
+### Configuration
 
-| Key | Default | Contract |
-|---|---:|---|
-| `readWindowMax` | `50` | Maximum `before` or `after` raw-event count. |
-| `persistedInspectConcurrency` | `4` | Maximum concurrent persisted-log inspections in one batch read; must be a positive safe integer. |
+The two inherited knobs are set through the mounted backend's config:
 
+| Field | Default | Meaning |
+|---|---|---|
+| `readWindowMax` | `50` | Maximum `before`/`after` raw events accepted by `readEvent` |
+| `persistedInspectConcurrency` | `4` | Concurrent persisted-log inspections in one batch title read |
+
+### Failures and recovery
+
+Failures are typed with a stable `SessionQueryError.code`. The ones you will meet: `SESSION_QUERY_SESSION_NOT_FOUND` when an id is absent; `SESSION_QUERY_SOURCE_CONFLICT` when live and persisted observations of one session disagree on immutable headers; `SESSION_QUERY_PERSISTENCE_FAILED` when mounted persistence is unreadable; `SESSION_QUERY_CORRUPT_SESSION` when a durable record fails Session validation; and `SESSION_QUERY_INVALID_SURFACE` when a loaded log breaks the surface contract. Reads targeting a known live session never consult persistence, so a failing backend cannot make current in-memory history unreadable.

+## Understand the implementation

+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the service and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The service is built on one separation and three commitments:
+
+- **Live-preferred logical corpus.** Every read resolves one consistent observation: live `ctx.sessions` wins, optional `ctx.sessionPersistence` fills the rest, and conflicting immutable headers fail rather than merge.
+- **Detached results.** All returned headers, events, and records are cloned; nothing exposes live state or a retained subscription.
+- **Exact reads concrete, search abstract.** Reads, filters, and traces are implemented here once; the two full-text methods are the only abstract surface a backend owns.
+- **One canonical surface fold.** `listEvents`, `readSurface`, and `traceEvent` validate the whole log with the same `dsh-session` fold, so search and traces agree with model-history derivation.
+
+The decision history lives in the [unified service decision](../../../.agents/notes/archived/architecture/2026-07-23-unified-session-query-service.md), the [tracing note](../../../.agents/notes/implemented/feature/2026-07-13-session-query-tracing.md), and the [SQLite provider note](../../../.agents/notes/implemented/feature/2026-07-10-sqlite-session-query-provider.md).

+
+### Corpus resolution
+
+`SessionCorpus` binds optional `ctx.sessionPersistence` through a fiber and resolves each read live-first: a known live target is snapshotted without consulting persistence; otherwise the session is listed, inspected non-mutatingly, and re-checked for a live attachment before cloning. Header compatibility is asserted between listed and loaded observations. Batch title reads run one metadata listing and bounded-concurrency inspections, isolating per-session failures while cancellation rejects the whole batch.
+
+### Reads and traces
+
+`readSession` replays the log through `Session.create` to reuse resume's validation. `readSurface`, `listEvents`, and `traceEvent` share one `foldSurface` pass that classifies events as `current`, `shadowed`, or `log-only` and validates zero-based contiguous seqs, surface-marker eligibility, and replacement or citation integrity; any violation fails with `SESSION_QUERY_INVALID_SURFACE`. Traces are one-shot: session lineage reads the corpus once and walks parents and descendant trees deterministically, and event traces follow positional replacers to the final node while keeping cited-source links non-transitive.

 # @deepseek-ai/dsh-session-query
 
 [English](README.md) | 中文
 
-`SessionQueryEngine` 是组合式抽象 `ctx.sessionQuery` 约定。它对实时 `ctx.sessions` 和可选的动态挂载 `ctx.sessionPersistence` 实现精确会话历史取回、关系跟踪和与提供方无关的过滤；具体后端实现它的两个全文方法。匹配 id 只产生一条记录：实时事件优先，而 `live` 和 `persisted` 会报告两种来源的可用性。如果不可变 header 存在冲突，则以 `SESSION_QUERY_SOURCE_CONFLICT` 失败。
+## 概述
 
-## 读取
+`dsh-session-query` 为代码调用方提供检索会话历史的唯一服务：读取完整原始日志、列出并过滤会话、折叠标题、读取带边界上下文的事件、追踪会话血缘与事件关系，并执行全文搜索。实时会话优先于持久化会话，且返回的每条记录都是脱离存储的克隆，因此结果始终描述同一一致时刻。精确读取、过滤与追踪为内置行为；全文搜索来自挂载的后端，已发布实现为 `dsh-session-query-sqlite`。当你需要以编程方式访问模型所看到的内容时，直接从代码使用它。设置与用法在前；实现内部细节放在下方可折叠的开发者章节中。
 
-- `listSessions(signal?)` 读取当前持久化元数据，以实时记录优先的方式合并它们，并按确定性的最新优先顺序返回克隆记录。
-- `readSession(sessionId)` 在执行与恢复相同的核心回放验证后，返回一份完整、脱离存储的原始日志；它绝不会将该会话放入实时存储。
-- `filterSessions(filters, signal?)` 对同一份克隆逻辑语料库应用与提供方无关的会话元数据和可用性谓词。
-- `filterEvents(sessionId, filters)` 提取第一方语义文档，并按 seq 升序应用与提供方无关的元数据和字面文本谓词。
-- `readTitleSnapshots(sessionIds, signal?)` 从一次实时优先的语料库观察中解析唯一 id，将取消信号传递给持久化列表查询和检查，并按顺序返回每个会话的结算结果，使某个缺失或格式错误的标题来源不会导致其他会话的结果被丢弃。每个实时来源直接 fold，每个持久化 worker fold 为脱离存储的 header/标题结果，并在出队下一个 id 前释放完整日志。取消会拒绝整个批次。`readTitleSnapshot(sessionId, signal?)` 是单次观察视图；`readTitle(sessionId, signal?)` 只返回其可选的 folded `session/title`。
-- `listEvents(sessionId)` 加载实时优先的原始日志，将每个事件分类为 `current`、`shadowed` 或 `log-only`；该分类使用共享 `dsh-session` 表层 fold。
-- `readSurface(sessionId)` 返回一个克隆 header、原始日志捕获边界，以及按模型历史顺序排列的完整折叠后当前表层。实时会话优先于持久化；压缩（compaction）只会在其替换追加之前或之后被观察，绝不会出现合成混合。
-- `readEvent(request, signal?)` 返回一个克隆 header、完整目标事件和有界的原始 seq 窗口。`before` 和 `after` 默认为 0，且不得超过 `readWindowMax`。
-- `traceSession(sessionId, signal?)` 只读取一次语料库，返回从直接父级向外的祖先，以及确定性的递归后代树。`complete: false` 标识第一个缺失父级；与目标相连的循环会以 `SESSION_QUERY_INVALID_LINEAGE` 失败。
-- `traceEvent(request, signal?)` 只加载一次逻辑日志，返回其克隆源 header、直接位置替换和直接引用的源事件链接。`replacementChain` 沿位置替换者跟踪到最终替换；源事件链接仍不传递。
+## 目录
 
-持久化是可选的，可动态挂载或卸载。已挂载持久化无法读取时，跨语料库列表和血缘跟踪以 `SESSION_QUERY_PERSISTENCE_FAILED` 失败；已经成功读取、但无法通过 Session 校验的持久化记录则以 `SESSION_QUERY_CORRUPT_SESSION` 失败。针对已知实时会话的标题读取、事件跟踪或事件读取不会查询持久化，因此持久化后端的健康状态无法使当前内存状态变得不可读。持久化标题和事件操作在加载前先执行列表查询，并在元数据不匹配时拒绝，而不会组合不一致的观察。血缘跟踪的取消信号会传递给持久化列表查询；事件跟踪和事件读取的取消信号会传递给持久化列表查询和检查。每项操作都会等待已启动的后端调用结算，然后使用信号的精确原因拒绝，即使后端忽略了该信号。针对已知实时会话且预先中止的标题读取、事件跟踪或事件读取会在 fold 或快照之前拒绝，且不查询持久化。批量标题观察执行一次元数据列表查询，使用最多 `persistedInspectConcurrency` 个 worker 检查唯一持久化 id，并保留每个标题自己观察到的 header，供下游授权使用。取消不会启动已排队检查，且只在已启动 worker 结算后拒绝。`listSessions()` 仍保持轻量，不加载日志或索引标题。

-## 过滤与提取
+-----
 
-`SessionResultFilter` 覆盖 id、可空 cwd、创建时间范围、可空父级和来源可用性。`SessionEventResultFilter` 覆盖 seq/时间范围、事件类型、表层和语义文本。过滤器数组使用 AND；同一列表子句内的值使用 OR。空列表值不匹配任何内容，范围包含端点，而格式错误的范围或封闭联合值以 `SESSION_QUERY_INVALID_FILTER` 失败。
+<a id="use-this-package"></a>
+## 使用本包
 
-文本子句刻意与 FTS 提供方无关：调用方文本会被转义为不区分大小写的 Unicode 正则表达式，每段连续空白匹配一个或多个空白字符。它是字面语义文本扫描，而非全文查询。`extractSessionEventText()` 和 `buildSessionEventSearchDocuments()` 定义共享的第一方文档投影；推理（reasoning）块、结构边界、流分片、请求 header 和未知声明合并变体不产生文档。
+当你需要读取或搜索会话历史、而不直接触碰会话服务或存储后端时，从应用代码使用 `ctx.sessionQuery`。该服务由具体后端插件提供——已发布组合挂载 `@deepseek-ai/dsh-session-query-sqlite`（[README](../session-query-sqlite/README.zh.md)）——因此本包从不单独挂载。一旦组合了后端，以下全部能力都可在 `ctx.sessionQuery` 上使用。
 
-## 全文方法
+### 你可以做什么
 
-`SessionQueryEngine.searchSessions(request, exec?)` 按匹配最强的事件对逻辑语料库分组；`searchEvents(request, exec?)` 搜索一个逻辑会话。这两个是服务仅有的抽象方法。两者都返回分页结果，其延续信息是由服务持有的带品牌 `SessionSearchCursor`；接受可选取消，并在不使用提供方专用数值分数的情况下提供摘录。事件搜索分页结果还携带来自与命中相同索引世代的克隆目标 header，使授权消费方可将策略绑定到此次载荷观察。搜索请求只接受事件元数据过滤器，因为字面文本过滤使用上文所述扫描路径。
+| 操作 | 你得到什么 |
+|---|---|
+| `listSessions()` | 每个逻辑会话，最新的在前，带 `live` 与 `persisted` 可用性标志 |
+| `readSession(id)` | 经过回放校验的完整原始事件日志，且不会让该会话变为实时 |
+| `filterSessions(filters)` | 匹配 AND 连接的元数据与可用性谓词的会话 |
+| `filterEvents(id, filters)` | 匹配元数据与字面文本谓词的语义事件文档 |
+| `readTitleSnapshots(ids)` | 每个会话的最新折叠标题，绑定到其来源 header |
+| `listEvents(id)` / `readSurface(id)` | 轻量逐事件记录，或完整的当前模型表层 |
+| `readEvent(request)` | 一个完整事件加其周围有界的原始日志窗口 |
+| `traceSession(id)` | 已知祖先链与递归后代树 |
+| `traceEvent(request)` | 一个事件的位置替换与被引用源事件关系 |
+| `searchSessions(request)` / `searchEvents(request)` | 全文搜索分页结果，由挂载的后端实现 |
 
-该包没有提供方协调器、回退实现或独立具体插件。具体服务后端继承已实现的读取、过滤和跟踪，同时负责全文观察、对账、排名、游标世代和查询执行；第一个实现是 [`@deepseek-ai/dsh-session-query-sqlite`](../session-query-sqlite/README.zh.md)。
+### 过滤器
 
-`SessionQueryError.code` 是一个封闭联合，覆盖请求验证、缺失目标、格式错误的表层、来源冲突、持久化/索引失败、取消，以及无效或陈旧游标；精确字面值在 [`src/config.ts`](src/config.ts) 中定义。
+`SessionResultFilter` 按 id、可空 cwd、创建时间范围、可空父级或来源可用性缩小会话范围；`SessionEventResultFilter` 按 seq/时间范围、事件类型、表层或字面文本缩小事件范围。过滤器数组使用 AND 连接，同一子句内的列表值使用 OR；空列表值不匹配任何内容，范围包含端点，格式错误的范围或未知的封闭联合值以 `SESSION_QUERY_INVALID_FILTER` 失败。
 
-`listEvents()`、`readSurface()` 和 `traceEvent()` 执行同一个单遍 `dsh-session` 表层 fold。只有当事件 seq 从零开始且连续、表层标记符合事件类型的适用性要求、源事件数组非空且无重复、引用指向较早事件，且每个位置替换都命名并引用它移除的每个表层节点时，加载的日志才有效；任何违规都以 `SESSION_QUERY_INVALID_SURFACE` 失败。
+文本子句是对所提取语义文本的字面、不区分大小写、空白灵活的扫描——而非全文查询。需要任意子字符串召回时使用它；需要排序后的全文结果时使用挂载后端的搜索方法。
 
-## 配置
+### 配置
 
-| 键 | 默认值 | 约定 |
-|---|---:|---|
-| `readWindowMax` | `50` | `before` 或 `after` 的最大原始事件数。 |
-| `persistedInspectConcurrency` | `4` | 一次批量读取中的最大并发持久化日志检查数；必须是正的安全整数。 |
+两个继承的旋钮通过挂载后端的配置设置：
 
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `readWindowMax` | `50` | `readEvent` 接受的 `before`/`after` 原始事件数上限 |
+| `persistedInspectConcurrency` | `4` | 一次批量标题读取中的并发持久化日志检查数 |
+
+### 失败与恢复
+
+失败带有稳定的 `SessionQueryError.code` 类型。你会遇到的包括：id 不存在时 `SESSION_QUERY_SESSION_NOT_FOUND`；同一会话的实时与持久化观察在不可变 header 上不一致时 `SESSION_QUERY_SOURCE_CONFLICT`；已挂载持久化不可读时 `SESSION_QUERY_PERSISTENCE_FAILED`；持久化记录未通过 Session 校验时 `SESSION_QUERY_CORRUPT_SESSION`；加载的日志破坏表层约定时 `SESSION_QUERY_INVALID_SURFACE`。针对已知实时会话的读取从不查询持久化，因此后端故障不会让当前内存历史变得不可读。

+
+### 设计理念
+
+本服务建立在一个分离与三项承诺之上：
+
+- **实时优先的逻辑语料库。** 每次读取都解析一个一致的观察：实时 `ctx.sessions` 优先，可选的 `ctx.sessionPersistence` 补充其余部分，冲突的不可变 header 宁可失败也不合并。
+- **脱离存储的结果。** 所有返回的 header、事件与记录都是克隆；不暴露实时状态，也不保留订阅。
+- **精确读取具体，搜索抽象。** 读取、过滤与追踪在此只实现一次；两个全文方法是由后端拥有的唯一抽象表面。
+- **一次规范的表层折叠。** `listEvents`、`readSurface` 与 `traceEvent` 使用同一个 `dsh-session` 折叠校验整个日志，因此搜索与追踪和模型历史推导一致。

-Workspace-authorized model tools over `ctx.sessionQuery`. The opt-in package depends only on the unified interface and registers `session_search`, `session_event_search`, `session_trace`, `session_event_trace`, and `session_event_read`; shipped host compositions do not mount it by default.
+## Summary
 
-## Configuration
+`dsh-tool-session-query` gives the model five read-only tools over session history: `session_search`, `session_event_search`, `session_trace`, `session_event_trace`, and `session_event_read`. The tools are workspace-authorized — a model can only reach sessions whose `cwd` exactly matches its own caller session — and results are cursor-free plain text, so the model can search prior work and follow a useful hit into its lineage or exact event data. The package is opt-in and not mounted by shipped host compositions: mounting it adds one concise guidance section and the five schemas to every request. Configuration and usage come first; the implementation internals live in a collapsible developer section below.
 
-| Key | Default | Meaning |
-|---|---:|---|
-| `maxSearchResults` | `100` | Maximum authorized non-self hits collected across internal provider pages |

+## Use this package
+
+Mount this package when the agent should be able to search its own prior sessions and inspect their relationships and events. The common path is explicit: mount the plugin over `ctx.sessionQuery` (backed by `dsh-session-query-sqlite`), then let the model call the tools.
+
+### When to choose it
+
+Choose it when a deployment wants model-driven retrieval of prior work — for example a coding agent that searches what it did in earlier sessions before starting a task. Avoid it when only programmatic retrieval is needed: `ctx.sessionQuery` itself serves code callers without the model-facing schema, prompt, and authorization layer.
+
+### Configuration
+
+| Field | Default | Meaning |
+|---|---|---|
+| `maxSearchResults` | `100` | Maximum authorized hits returned by one search call |
 | `searchTimeoutMs` | `30000` | Cooperative deadline attached to both full-text search tools |
 
-The tools derive caller authority from `ToolExecution.exec.agent`. Cross-session access requires exact equality between the target and caller session `cwd` values; a caller without `cwd` can inspect only itself. Search never exposes paging controls or a model-controlled result limit. Cancellation retains the caller's reason, and timestamp filters require an explicit `Z` or numeric offset and include both endpoints.
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-tool-session-query) is the exhaustive source for every accepted field and its JSDoc.
 
-`session_search` always omits the caller session. Requested parent ids are deduplicated and checked against caller-workspace authority before FTS; only authorized ids reach the provider, while missing and cross-workspace guesses behave identically and the root marker remains independently ORed. A current-session `session_event_search` stops immediately before the step that invoked it, so the active assistant output and logged tool call cannot match themselves. Direct targets are authorized before trace, event, or title reads. Lineage output replaces unauthorized ancestor and descendant boundaries with markers that contain no hidden session id.
+### What the model can do
 
-Provider failures log available diagnostics but return the fixed `SESSION_QUERY_TOOL_FAILED` code and message to the model. Local argument-validation and authorization errors retain their precise tool-owned messages.
+| Tool | What the model gets |
+|---|---|
+| `session_search` | Sessions matching a literal query, ranked, with title and best-match excerpt; always omits the caller session |
+| `session_event_search` | Events matching a literal query inside one authorized session; for the current session it stops before the step that invoked it |
+| `session_trace` | The authorized ancestor chain and descendant tree of one session; unauthorized boundaries appear as markers without hidden ids |
+| `session_event_trace` | One event's positional replacements and cited source-event relationships |
+| `session_event_read` | One full unabridged event as JSON, plus optional neighboring event summaries |
 
-The package deliberately performs no byte or character truncation and does not import a spill backend. Deployments that need bounded inline output mount `@deepseek-ai/dsh-spill-policy`, which can replace the rendered text after execution while retaining the complete result.
+Workspace authority is conservative: cross-session access requires exact `cwd` equality between target and caller session, and a caller without `cwd` can inspect only itself. Requested parent ids are deduplicated and authority-checked before search; missing and cross-workspace guesses behave identically. Search results are cursor-free: a capped result asks the model to narrow its query, and never exposes provider cursors, offsets, page sizes, or a model-controlled limit. Timestamps at the tool boundary are timezone-qualified ISO 8601 and become inclusive epoch-millisecond filters.
 
+### Failures and recovery
+
+Every trusted query-service call crosses one error sanitizer: caller cancellation is preserved exactly, corpus and provider diagnostics go to the internal log, and unsafe or unprintable failures fall back to the fixed `SESSION_QUERY_TOOL_FAILED` code and message. Local argument-validation and authorization errors keep their precise tool-owned messages (`SESSION_QUERY_TOOL_UNAUTHORIZED` for a target outside the caller workspace). The package performs no byte or character truncation and does not import a spill backend; deployments that need bounded inline output mount `@deepseek-ai/dsh-spill-policy`, which can replace oversized rendered text while retaining the complete result.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the tools and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The consumer is built on one separation and three commitments:
+
+- **Narrow read-only tools.** Five tools with flat snake-case schemas, each teaching one follow-up step; no cursor, offset, page-size, or model-controlled limit ever reaches the model.
+- **Authority derived from the caller, never the model.** Caller identity comes from `ToolExecution.exec.agent`; workspace is exact-string `cwd` equality, re-checked against the header observed with each result.
+- **One model-boundary sanitizer.** Every trusted `ctx.sessionQuery` call goes through the service boundary, which preserves cancellation and contains diagnostic and classification failures.
+- **No second truncation format.** Results stay complete; the generic spill policy owns bounded inline output.
+
+The design history lives in the [model-facing session query tools note](../../../.agents/notes/implemented/feature/2026-07-24-model-facing-session-query-tools.md) and the [session-search-not-shipped-default note](../../../.agents/notes/implemented/feature/2026-08-02-session-search-not-shipped-default.md).
+
+### Source map
+
+| File | Role |
+|---|---|

+| [`src/operations.ts`](src/operations.ts) | The five operation workflows |
+| [`src/presentation.ts`](src/presentation.ts) | Text result rendering and tool-call cards |
+
+### Operation flow
+
+Each executor derives the caller, normalizes the model's arguments into service filters, authorizes the target (or the requested parent ids) against the caller workspace, and collects results through the service boundary. Both search tools page internally through provider cursors while the observed generation stays valid, stopping at `maxSearchResults`; because one search consumes generation-bound provider cursors, the two search tools execute exclusively with sibling tool calls, while the three exact trace/read tools opt into parallel execution. Lineage output replaces unauthorized ancestor and descendant boundaries with markers containing no hidden session id.

 # @deepseek-ai/dsh-tool-session-query
 
 [English](README.md) | 中文
 
-位于 `ctx.sessionQuery` 之上、经工作区授权的模型工具。该 opt-in 包只依赖统一接口，并注册 `session_search`、`session_event_search`、`session_trace`、`session_event_trace` 和 `session_event_read`；已发布的宿主组合默认不挂载它。
+## 概述
 
-## 配置
+`dsh-tool-session-query` 给模型提供五个会话历史只读工具：`session_search`、`session_event_search`、`session_trace`、`session_event_trace` 与 `session_event_read`。工具经工作区授权——模型只能访问 `cwd` 与其自身调用方会话完全相同的会话——结果是无游标的纯文本，因此模型可以搜索既往工作，并顺着有用命中进入其血缘或精确事件数据。本包是 opt-in，已发布宿主组合默认不挂载：挂载后每次请求都会增加一个精简指引章节与五个 schema。配置与用法在前；实现内部细节放在下方可折叠的开发者章节中。

+## 使用本包
+
+当 agent 应该能搜索自己的既往会话并检查其关系与事件时挂载本包。常用路径是显式的：在 `ctx.sessionQuery`（由 `dsh-session-query-sqlite` 支撑）之上挂载插件，然后让模型调用这些工具。
+
+### 何时选择
+
+当部署需要模型驱动的既往工作检索时选择它——例如编程 agent 在开始任务前搜索更早会话中做过的事。只需要程序化检索时避免使用：`ctx.sessionQuery` 本身服务代码调用方，无需面向模型的 schema、提示词与授权层。
+
+### 配置
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `maxSearchResults` | `100` | 一次搜索调用返回的最大已授权命中数 |
 | `searchTimeoutMs` | `30000` | 附加到两个全文搜索工具的协作式截止时间 |
 
-工具根据 `ToolExecution.exec.agent` 派生调用方权限。跨会话访问要求目标和调用方会话的 `cwd` 值严格相等；没有 `cwd` 的调用方只能检查自己。搜索绝不公开分页控制项或模型可控的结果上限。取消会保留调用方原因，时间戳过滤器要求显式 `Z` 或数字偏移，并包含两个端点。
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-tool-session-query)是每个受支持字段及其 JSDoc 的穷尽式真源。
 
-`session_search` 始终省略调用方会话。请求的父 id 会被去重，并在 FTS 前根据调用方工作区权限检查；只有已授权 id 会到达提供方，而缺失猜测和跨工作区猜测的行为完全相同，root 标记仍独立使用 OR。当前会话中的 `session_event_search` 会在调用它的步骤之前立即停止，因此当前 assistant 输出和已记录工具调用无法匹配自身。直接目标在跟踪、事件或标题读取前完成授权。血缘输出会用不含隐藏会话 id 的标记替换未授权祖先和后代边界。
+### 模型可以做什么
 
-提供方失败会记录可用的诊断信息，但向模型返回固定的 `SESSION_QUERY_TOOL_FAILED` 代码和消息。本地参数校验和授权错误保留精确的工具自有消息。
+| 工具 | 模型得到什么 |
+|---|---|
+| `session_search` | 匹配字面查询的会话，经排序，带标题与最佳匹配摘录；始终省略调用方会话 |
+| `session_event_search` | 一个已授权会话内匹配字面查询的事件；针对当前会话时，在调用它的步骤之前停止 |
+| `session_trace` | 一个会话的已授权祖先链与后代树；未授权边界以不含隐藏 id 的标记出现 |
+| `session_event_trace` | 一个事件的位置替换与被引用源事件关系 |
+| `session_event_read` | 一个完整未删节事件（JSON），加可选的事件邻接摘要 |
 
-该包刻意不执行字节或字符截断，也不导入 spill 后端。需要限制内联输出的部署应挂载 `@deepseek-ai/dsh-spill-policy`，它可在执行后替换已渲染文本，同时保留完整结果。
+工作区授权是保守的：跨会话访问要求目标与调用方会话的 `cwd` 严格相等，没有 `cwd` 的调用方只能检查自己。请求的父 id 会在搜索前去重并按权限检查；缺失与跨工作区猜测行为完全相同。搜索结果无游标：结果达到上限时请模型缩小查询，绝不暴露提供方游标、偏移、分页大小或模型可控上限。工具边界的时间戳是带时区限定的 ISO 8601，并转换为包含端点的 epoch 毫秒过滤器。
 
+### 失败与恢复
+
+每个可信查询服务调用都经过一个错误净化器：调用方取消被精确保留，语料库与提供方诊断进入内部日志，不安全或不可打印的失败回退到固定 `SESSION_QUERY_TOOL_FAILED` 代码与消息。本地参数校验与授权错误保留精确的工具自有消息（目标在调用方工作区之外时为 `SESSION_QUERY_TOOL_UNAUTHORIZED`）。本包不执行字节或字符截断，也不导入 spill 后端；需要限制内联输出的部署应挂载 `@deepseek-ai/dsh-spill-policy`，它可以在保留完整结果的同时替换过大的已渲染文本。

+
+本节解释工具背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+本消费方建立在一个分离与三项承诺之上：
+
+- **窄而只读的工具。** 五个带扁平 snake-case schema 的工具，每个都引导一个后续步骤；游标、偏移、分页大小或模型可控上限永远不会到达模型。
+- **授权来自调用方，绝不由模型提供。** 调用方身份来自 `ToolExecution.exec.agent`；工作区是字符串精确 `cwd` 相等，并对照每次结果观察到的 header 重新校验。
+- **一个模型边界净化器。** 每个可信 `ctx.sessionQuery` 调用都经过服务边界，它保留取消并包含诊断与分类失败。
+- **不引入第二种截断格式。** 结果保持完整；通用 spill 策略负责有界内联输出。
+
+设计历史记录在[面向模型的会话查询工具笔记](../../../.agents/notes/implemented/feature/2026-07-24-model-facing-session-query-tools.zh.md)与 [session-search-not-shipped-default 笔记](../../../.agents/notes/implemented/feature/2026-08-02-session-search-not-shipped-default.zh.md)中。
+
+### 源码地图

+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：配置、提示词章节、五个工具注册 |
+| [`src/input.ts`](src/input.ts) | 模型 schema、参数规范化、过滤器构造 |

+
+### 操作流程
+
+每个执行器先派生调用方，把模型的参数规范化为服务过滤器，对照调用方工作区授权目标（或请求的父 id），然后通过服务边界收集结果。两个搜索工具在观察世代仍有效时内部翻页消费提供方游标，停在 `maxSearchResults`；由于一次搜索会消费与世代绑定的提供方游标，两个搜索工具与同级工具调用排他执行，而三个精确追踪/读取工具选择并行执行。血缘输出用不含隐藏会话 id 的标记替换未授权祖先与后代边界。

 # session/ — durable session data plane
 
 English | [中文](README.zh.md)
 
-The durable family around `core/session`'s live in-memory service: the persistence seam with its storage backends and checkpoint policy, the projection seam that serves whole log-derived values, log-backed titles, and outbound session telemetry. All **product** packages. `session-query/` remains a sibling group: the read/tool surface is consumed independently of persistence internals.
+## Summary
 
-## Persistence
+The session group makes an agent's conversation durable and reusable outside the live loop: the persistence seam stores the event log and restores it on resume, the checkpoint policy keeps requests, tool side effects, and completed steps durable before the next action, projections serve whole log-derived values to client carriers, titles name each session from its content, and telemetry reports session activity outbound. Pick a persistence backend first — JSONL is the shipped default, SQLite an opt-in single-database backend — then add the checkpoint policy and any projection, title, or telemetry packages the deployment needs. This page maps the group; every package README owns its contract, and `session-query/` is a sibling group whose read/tool surface consumes persistence independently.

-这是围绕 `core/session` 内存中运行的服务构建的持久功能族：包括持久化 seam 及其存储后端和检查点策略、提供日志派生全量值的投影 seam、日志支持的标题，以及外发会话遥测。它们全部都是**产品**包（package）。`session-query/` 仍是同级独立组：读取／工具接口的消费不依赖持久化内部实现。
+## 概述
 
-## 持久化
+session 组让 agent（智能体）的对话在实时 loop 之外持久可复用：持久化 seam 存储事件日志并在恢复时还原，检查点策略让请求、工具副作用与已完成步骤在下一步动作前持久化，投影向客户端载体提供日志派生的完整值，标题根据会话内容为其命名，遥测则向外上报会话活动。先选持久化后端——JSONL 是随产品交付的默认项，SQLite 是可选启用、单库的后端——再按部署需要挂载检查点策略以及投影、标题或遥测包。本页是组的映射；每个包 README 负责各自的约定，`session-query/` 是同级独立组，其读取／工具接口独立消费持久化。

-Semantic durability policy for persisted agents. It checkpoints the event-sourced session before a model adapter receives a request, before a top-level tool body may produce an external side effect, and at each `agent/pre-step` boundary so the preceding response and ordered tool results are durable before the next request.
+## Summary
 
-## Plugin (namespace: `session-checkpoint-policy`)
+`dsh-session-checkpoint-policy` is a zero-config plugin that makes a persisted session durable at the moments that matter: before a model request reaches the adapter, before a top-level tool body can produce an external side effect, and at each step boundary so the preceding response and tool results are stored before the next request. Load it beside one persistence backend, and a crash after any checkpoint resumes with the recorded work — a request, a tool call, or a completed step — instead of losing it. The policy adds no prompt, tool schema, or configuration; checkpoint failures are fail-closed, so neither the adapter nor a top-level tool body runs when the durable write cannot be confirmed. Streaming `assistant/chunk` events get no per-chunk checkpoint, and a persisted call without a result records an unknown outcome rather than retrying automatically.
 
-This zero-config function plugin consumes `ctx.sessions`, `ctx.llm`, `ctx.tools`, and the presence of `ctx.sessionPersistence`. Load it beside one persistence backend:

+## Use this package
+
+Mount this plugin in any composition that persists sessions and must survive a crash without redoing or losing work. Persistence and checkpoint scheduling are separate plugins: a backend stores the event log, and this policy decides when the store must be flushed.
+
+### When to choose it
+
+Choose it for every persisted agent that can be interrupted — a crash between a recorded tool call and its result, or between a model request and its response, is exactly the failure this policy contains. Loading a backend without it is valid but weaker: events still inside the backend's batching window or an outstanding write can be lost. Skip the policy when nothing persists sessions, or when a specialized deployment deliberately replaces the checkpoint schedule.
+
+### Minimal configuration
+
+No configuration fields exist; the plugin is a single load beside one persistence backend:

@@ -16,12 +43,52 @@ This zero-config function plugin consumes `ctx.sessions`, `ctx.llm`, `ctx.tools`
   name: '@deepseek-ai/dsh-session-checkpoint-policy'
 ```
 
-Persistence and checkpoint scheduling are intentionally separate Cordis plugins. A persistence backend starts bounded background batches for `session/event` appends and makes each requested `session/flush` an immediate quiescence barrier; this policy chooses the request, tool-dispatch, and next-step barriers. Loading a backend without this policy is valid, but a crash may lose events still inside the configured batching window or an outstanding write. First-party persisted apps and runtimes mount both plugins explicitly; a specialized deployment may deliberately omit or replace the policy.
+### What becomes durable
 
-The policy wraps `llm/stream` lazily, so the downstream stream is not constructed until the live session's buffered request events are durable. It wraps `tools/execute` after pre-execute policy and guards; a top-level tool body runs only after its recorded call is durable. If cancellation lands while that flush is pending, the wrapper returns the canonical `ABORTED_BEFORE_DISPATCH` result without entering the tool body. Nested tool dispatches reuse the outer model-visible call's checkpoint. `agent/pre-step` persists the preceding response/result batch before request derivation.
+Three barriers are checkpointed. The model request is flushed before the adapter stream is constructed, so a crash before a response cannot replay an unpersisted request. A top-level tool call is flushed before the tool body runs, so a recorded call is durable before any external side effect; nested tool dispatches reuse the outer call's checkpoint. At each `agent/pre-step` boundary, everything the preceding step committed — its response and ordered tool results — is flushed before the next request is derived.
 
-Checkpoint rejection is fail-closed at the model and tool boundaries: neither the adapter nor the top-level tool body runs. A step-boundary rejection fails the turn before another request starts. Concurrent tool checkpoints share the session store's serialized persistence drain and cannot duplicate sequence numbers.
+### Observable behavior and failures
 
+After a checkpoint, the checkpointed work is durable: resume restores it from the store like any persisted session. If cancellation lands while a tool checkpoint flush is pending, the wrapper returns the canonical `ABORTED_BEFORE_DISPATCH` result and never enters the tool body. A checkpoint rejection is fail-closed at both boundaries — the adapter or top-level tool body does not run — and a step-boundary rejection fails the turn before another request starts.

+
+This section explains how the policy joins the loop and the persistence seam; the observable contract is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The plugin is a listener-only composition over three seams, with no state of its own: it wraps `llm/stream` so the downstream stream is not constructed until the live session's buffered request events are durable, wraps `tools/execute` after pre-execute policy and guards so a top-level tool body runs only after its recorded call is durable, and listens to `agent/pre-step` to persist the preceding response/result batch before request derivation. The session store's flush is the shared durability barrier; concurrent tool checkpoints serialize through it and cannot duplicate sequence numbers.

-已持久化的 agent（智能体）的语义持久性策略。它会在模型适配器收到请求前、顶层工具正文可产生外部副作用前，以及每个 `agent/pre-step` 边界为事件溯源会话创建检查点，使前一响应与有序工具结果在下一个请求前已持久化。

+`dsh-session-checkpoint-policy` 是一个零配置插件，让持久化会话在关键时刻变得持久：模型请求到达适配器之前、顶层工具正文可能产生外部副作用之前，以及每个步骤边界——使前一响应与工具结果在下一个请求前已存储。把它与一个持久化后端一起加载后，任何检查点之后的崩溃都能恢复已记录的工作——请求、工具调用或已完成步骤——而不会丢失。该策略不添加提示词、工具 schema 或配置；检查点失败按失败即阻止原则处理，因此在无法确认持久写入时，适配器与顶层工具正文都不会运行。流式 `assistant/chunk` 事件没有逐分片检查点，而没有结果的持久调用会记录为未知结果，而不是自动重试。

-持久化与检查点调度刻意拆分为独立 Cordis 插件。持久化后端会为追加的 `session/event` 启动有界后台批次，并把每个已请求的 `session/flush` 变成即时完全停稳屏障；该策略选择请求、工具分派和下一步骤屏障。不带此策略加载后端是有效的，但崩溃可能丢失仍位于已配置批处理窗口内的事件，或尚未完成的写入。第一方持久化应用和运行时显式挂载两个插件；专用部署可以刻意省略或替换策略。
+### 什么会变得持久
 
-策略延迟包装 `llm/stream`，因此下游流只会在活动会话中缓冲的请求事件已持久化后构造。它在预执行策略和防护机制之后包装 `tools/execute`；只有在已记录调用已持久化后，顶层工具正文才会运行。如果取消在 flush 等待期间到达，包装层会返回规范的 `ABORTED_BEFORE_DISPATCH` 结果，不进入工具正文。嵌套工具分派重用外层模型可见调用的检查点。`agent/pre-step` 在派生请求前持久化前一响应/结果批次。
+三个屏障会被检查点化。模型请求在适配器流构造前被刷新，因此响应前的崩溃不会重放未持久化的请求。顶层工具调用在工具正文运行前被刷新，因此已记录调用在任何外部副作用前已持久；嵌套工具分派复用外层调用的检查点。在每个 `agent/pre-step` 边界，前一步骤提交的一切——其响应与有序工具结果——在派生下一个请求前被刷新。
 
-在模型和工具边界，检查点被拒绝时会按失败即阻止原则处理：适配器和顶层工具正文都不运行。步骤边界处的检查点被拒绝会在另一个请求开始前使轮次失败。并发工具检查点共享会话存储的串行持久化排空流程，不会产生重复的序列号。
+### 可观察行为与失败
 
+检查点之后，被检查点化的工作即已持久：恢复像任何持久化会话一样从存储还原它。如果取消在工具检查点 flush 等待期间到达，包装层会返回规范的 `ABORTED_BEFORE_DISPATCH` 结果，绝不进入工具正文。检查点拒绝在两个边界都按失败即阻止处理——适配器或顶层工具正文不运行——步骤边界的拒绝会在另一个请求开始前使轮次失败。

 ## Request field
 
 For a request carrying a live `sessionId`, the plugin folds the greatest accepted watermark for that exact Session identity, snapshots `Session.events`, and sends the contiguous suffix after the watermark. A process-local fold scans each event once and consumes later appends incrementally; restart and HMR rebuild it from the durable log. The version-1 field contains the immutable `SessionHeader`, `afterSeq`, `throughSeq`, and every complete canonical `SessionEvent` in that range as a direct array element. Forked sessions ignore inherited parent watermarks because each watermark records the Session id sent on the accepted request.

 ## Acceptance and retry
 
 The DeepSeek adapter calls the prepared contribution's `accept()` after HTTP 2xx, before it consumes the SSE body. Acceptance appends `session-log-deepseek/delivery-accepted` with the uploaded `throughSeq`; the next request uploads that event as part of its new suffix. Transport and non-2xx failures append no acceptance record, so later requests resend the uncertain range. Concurrent deliveries may be accepted out of order; folding the maximum matching `throughSeq` prevents cursor regression.

-The JSONL durable session-persistence backend — a concrete `SessionPersistence` (the `dsh-session-persistence` seam). Each session has one append-only logical JSONL log, stored as `.jsonl.zstd` by default or raw `.jsonl` when compression is disabled.
+## Summary
 
-## On-disk layout
+`dsh-session-persistence-jsonl` stores each session in its own append-only JSONL log — checksummed Zstandard frames by default, raw newline-delimited lines when compression is disabled. It serves the same logical `SessionEvent` stream as any persistence backend, so choosing it changes nothing for the agent loop, the model, or replay; compression, packing, and crash recovery are storage-internal details. Choose it when consumers need a per-session artifact on disk: `locate(meta)` returns the transcript path, and the logs are readable as plain lines when `compression: 'none'` is selected. A root directory is the one required configuration; durability, lazy materialization, and interrupted-turn recovery come with the backend.

+Mount this backend when a composition needs durable sessions backed by per-session files. The common path is explicit: load the session service, mount the backend, and give it a root directory.
+
+### When to choose it
+
+Choose this backend when consumers benefit from one artifact per session — navigation, external tooling, or a raw line-readable log. Choose [SQLite](../session-persistence-sqlite/README.md) when a single queryable database fits the deployment instead. The backend keeps sessions under a deployment-controlled root: project-local, shared, temporary, or centralized.

-- The first logical line is the immutable `SessionHeader` tagged `{ type: 'session', version, id, cwd?, createdAt, parentSession?, seedLength?, origin?, delegationDepth, agentPreset? }`. `delegationDepth` is required on disk and is `0` for a top-level session; a missing or invalid value rejects the log. `agentPreset` is durable because it decides the resumed session's tools and prompt — restoring a different composition would replay history the model can no longer act on. Every subsequent logical line is one storage record; `assistant/chunk` events are never dropped, and `seq` stays contiguous across the decoded log (`events[i].seq === i`).
-- A storage record is a `SessionEvent` JSON verbatim, or — for an eligible run when `packChunks` is enabled — a **packed chunk row** (`text-chunks` / `reasoning-chunks` / `tool-call-chunks`; bare slash-less tags like the header's `session`, so row tags cannot be confused with event types): one line holding a run of ≥3 consecutive same-block `assistant/chunk` delta events, `seq0`/`time0` plus per-member `dt` gaps reconstructing every member's `seq`/`time` exactly. The lossless codec lives in `@deepseek-ai/dsh-session` (`packChunkRuns`/`decodeStorageRecord`) and whitelists exact shapes — anything unrecognized stores verbatim. Reading is layout-blind: `load` always decodes rows, so packed, unpacked, and mixed files load identically.
-- The project directory keeps the normalized cwd readable for navigation and is bounded for filesystem component limits. Separator replacement and truncation are intentionally lossy, so cwd strings that normalize alike share a project directory; session ids still select distinct session directories. On a case-insensitive filesystem, identity validation accepts an alternate path spelling only when filesystem canonicalization resolves both spellings to the same transcript. The configured root remains deployment-controlled: it may be project-local, shared, temporary, or centralized. The [project-session directory decision](../../../.agents/notes/implemented/architecture/2026-07-24-project-session-directories.md) records this tradeoff.
-- Session ids are unvalidated branded strings, so they are injectively escaped to a single safe path segment before use (no traversal, no collision). The resulting directory is reserved for additional session-owned artifacts; discovery reads only the fixed transcript filename.
+Session ids are injectively escaped to one safe path segment before use (no traversal, no collision).

-| `root` | `string` (required) | Root directory for all session files. **No default** — a `process.cwd()` default would scatter files as the process's cwd changes (bash calls, subprocesses). An existing root must be a readable directory; an absent root is created on first materialization. |
-| `packChunks` | `boolean` (default `true`) | Write eligible delta-chunk runs as packed rows (~60% smaller logical logs measured on a real coding session). Set `false` for one-event-per-line diagnostics; reading packed rows works regardless of this write-side switch. |
-| `compression` | `'zstd' \| 'none'` | Defaults to `'zstd'`; `'none'` retains newline-delimited UTF-8 text. |

-| `writeBatchMaxDelayMs` | positive integer (default `200`) | Fixed coalescing window after an idle live-event queue receives work. Later events do not reset it; flush and teardown bypass it. It does not bound event-loop, serialized-operation, or backend latency. At most Node's `2_147_483_647` ms timer limit. |
+A session is materialized lazily: `create(meta)` writes nothing, and the first `append` writes and `fsync`s the encoded header and first batch through a no-overwrite publish — so a created-but-never-appended session leaves nothing on disk unless a lifecycle consumer calls `ensureMaterialized`, which publishes one header frame without an event. Flushed events are never rewritten; each subsequent batch appends lines or one compressed frame, and a caught write or sync failure rolls the file back to its prior length. After a crash, `load` preserves an interrupted final turn: it keeps the complete decoded records of an incomplete last frame, truncates from that frame's start, and re-encodes the records with the synthetic tool, step, and turn closers required by the shared persistence contract. Only a never-fully-written torn tail is discarded; checksum, decompression, or structural failure in the committed prefix rejects as corruption.
 
-`locate(meta)` returns `{ kind: 'jsonl', path }` for the fixed transcript inside the resolved project/session directories. It performs no filesystem I/O: the target can be returned before the directory or file exists, and an existing file contains only the last flushed prefix.
+### Reading the logs
 
-## Physical encoding
+`inspect(id)` returns an immutable balanced view without committing recovery. `readFrom(id, fromSeq)` returns stored events at or past a sequence number for watermark consumers; sequential media like JSONL parse the whole artifact and skip forward. With `compression: 'none'`, the log is newline-delimited text an external reader can consume directly; the compressed default must be read through the backend.
 
-The default artifact is a standard concatenation of independent [Zstandard frames](../../../.agents/notes/implemented/architecture/2026-07-19-zstandard-jsonl-session-logs.md): one checksummed frame containing only the header line, followed by one checksummed frame per durable append batch. The backend uses Node's built-in Zstandard API with its default compression level and exposes no level knob. Listing reads and validates only the header frame. `compression: 'none'` keeps the same logical lines in the original raw representation.
+-----
 
-A root belongs to one encoding. Startup discovery and targeted lookup reject the opposite suffix with an error naming the incompatible artifact and instructing the caller to select the matching mode or a separate root. Flat `<project>/<id>.jsonl*` artifacts are also rejected instead of ignored. There is no migration, mixed-root fallback, or dual write.

-- **Bound storage identity.** Lookup requires one matching session directory across the readable project directories, then verifies that the header id equals the requested id and that the header's id/cwd derive the selected transcript path. Listing applies the same path check and rejects duplicate ids. Identity failures occur before repair or append.
-- **Lazy materialization.** `create(meta)` writes nothing; on the first `append`, the backend writes and `fsync`s the encoded header and first batch in a temporary file. POSIX publishes it without overwrite via a hard link and `fsync`s the parent directory. Windows publishes it without overwrite via `MoveFileExW(..., MOVEFILE_WRITE_THROUGH)` and creates missing directories through the same write-through pattern. A created-but-never-appended session leaves nothing on disk and is absent from `list` unless a lifecycle consumer explicitly calls `ensureMaterialized`, which publishes one header frame without adding an event.
-- **Append-only.** Flushed events are never rewritten. Subsequent raw batches append lines; compressed batches append one frame. Both paths `fsync`, and a caught write or sync failure rolls the file back to its prior byte length.
-- **Crash recovery — preserve valid tail work.** `load` validates every complete compressed frame and scans their decompressed JSONL. If the last frame is structurally incomplete, the reader keeps its complete decoded records, truncates from that frame's start, and re-encodes those records with the synthetic tool, step, and turn closers required by the shared [persistence contract](../../../.agents/notes/implemented/architecture/2026-06-14-session-persistence.md). Raw mode truncates from its first incomplete line. An existing compressed artifact with no complete header frame, a checksum/decompression failure in a complete frame, or a defect at or before the last committed `turn/end` is corruption and rejects.
-- **Non-mutating inspection.** `inspect()` returns an immutable balanced logical view and may synthesize recovery closers in memory, without truncating an incomplete tail or changing the lightweight revision.
-- **Contiguous-seq.** `append` rejects a batch whose first `seq` does not continue the stored log, and rejects non-JSON-serializable `event.data` naming the offending event type.
-- **Lightweight revisions.** `listSnapshots(signal?)` identifies a log by its device, inode, size, and nanosecond timestamps, avoiding a full-log parse while changing after append, repair, replacement, or store changes. A full-prefix read requires the same identity before and after reading the bytes, and `readStoredRevision()` uses that identity to validate retained preparations without loading the log. Snapshot listing forwards the exact signal through artifact discovery and checks cancellation around every `stat`; because filesystem `stat` is not interruptible, cancellation waits for the active call to settle, then rejects without starting another.
+This section explains the physical encoding and write path; the observable contract is covered in [Use this package](#use-this-package).
 
-## Write path
+### Design concept
 
-The plugin copies frozen session events into one controller per live session. The first pending event starts the configured fixed batching window, and later events join without resetting it. Expiry starts one durable append; events admitted during that write form a separately bounded follow-up batch. `session/flush` cancels the wait and drains current and pending batches. A per-session cursor prevents resumed sessions from re-appending stored events, and live sessions are seeded when the plugin loads. The owning backend instance serializes operations for one session; disposal drains every retained controller before teardown. Every logical event remains present: batching only lets one compressed frame or raw fsync carry more records.
+The backend is a thin storage layer over the shared [PersistenceCoordinator](../session-persistence/README.md#understand-the-implementation): it loads stored records, appends batches, commits repairs, and delegates lifecycle orchestration to the coordinator. Its physical identity is a file revision: device, inode, size, and nanosecond timestamps identify one log and change after append or repair, which is what `listSnapshots` and retained-preparation validation use.
 
+### Physical encoding
+
+The default artifact is a standard concatenation of independent [Zstandard frames](../../../.agents/notes/implemented/architecture/2026-07-19-zstandard-jsonl-session-logs.md): one checksummed frame containing only the header line, then one checksummed frame per durable append batch, using Node's built-in Zstandard API at its default compression level (no level knob). Listing reads and validates only the header frame. A root belongs to one encoding: startup discovery and targeted lookup reject the opposite suffix, and there is no format or compression migration, mixed-root fallback, or dual write. When `packChunks` is enabled, an eligible run of ≥3 consecutive same-block `assistant/chunk` delta events becomes one packed row (`text-chunks`/`reasoning-chunks`/`tool-call-chunks`) whose `seq0`/`time0` and per-member `dt` gaps reconstruct every member exactly; the lossless codec lives in `dsh-session` and reading is layout-blind, so packed, unpacked, and mixed files load identically.

-JSONL 持久会话存储后端：`SessionPersistence` 的一个具体实现（`dsh-session-persistence` seam）。每个会话有一个仅追加的逻辑 JSONL 日志，默认存储为 `.jsonl.zstd`；禁用压缩时使用原始 `.jsonl`。
+## 概述
 
-## 磁盘布局
+`dsh-session-persistence-jsonl` 把每个会话存为一份仅追加 JSONL 日志——默认以带校验和的 Zstandard 帧存储，禁用压缩时以换行分隔的原始文本行存储。它提供与任何持久化后端相同的逻辑 `SessionEvent` 流，因此选择它不会改变 agent loop、模型或回放的任何行为；压缩、打包与崩溃恢复都是存储内部细节。当消费方需要按会话的磁盘产物时选择它：`locate(meta)` 返回 transcript 路径，选择 `compression: 'none'` 后日志可作为纯文本按行读取。根目录是唯一必填配置；持久性、延迟实体化与中断轮次恢复都随后端提供。

+本节说明物理编码与写入路径；可观察约定已在[使用本包](#use-this-package)中说明。
 
-## 写入路径
+### 设计理念
 
-插件将冻结的会话事件复制到每个活动会话各自的 controller。第一个待处理事件会开启配置的固定批处理窗口，后续事件会加入但不会重置截止时间。窗口到期后会启动一次持久化追加；该次写入期间接纳的事件会形成另一个独立有界的后续批次。`session/flush` 会取消等待并排空当前与待处理批次。每会话游标防止恢复后的会话重新 append 已存储事件，插件加载时会为活动会话设置初始状态。所属后端实例串行化单会话操作；dispose（资源释放）会在拆卸前排空每个保留的 controller。每个逻辑事件都会保留：批处理只让单个压缩帧或一次原始 JSONL fsync 承载更多记录。
+该后端是共享 [PersistenceCoordinator](../session-persistence/README.zh.md#understand-the-implementation) 之上的一层薄存储：它加载已存储记录、追加批次、提交修复，并把生命周期编排委托给协调器。其物理身份是文件修订值：device、inode、size 与纳秒时间戳标识一份日志，并在追加或修复后改变，这正是 `listSnapshots` 与保留准备结果校验所使用的身份。
 
+### 物理编码
+
+默认产物是独立 [Zstandard 帧](../../../.agents/notes/implemented/architecture/2026-07-19-zstandard-jsonl-session-logs.zh.md) 的标准拼接：一个仅包含 header 行的带校验和帧，后跟每个持久 append 批次一个带校验和帧，使用 Node 内置 Zstandard API 的默认压缩级别（无级别开关）。列表只读取并验证 header 帧。一个根只属于一种编码：启动发现与定向查找会拒绝相反后缀，且不提供格式或压缩迁移、混合根回退或双写。启用 `packChunks` 时，符合条件的 ≥3 个连续同 block `assistant/chunk` delta 事件连续段会变成一行打包行（`text-chunks`/`reasoning-chunks`/`tool-call-chunks`），其 `seq0`/`time0` 与各成员的 `dt` 间隔精确重建每个成员；无损 codec 位于 `dsh-session`，读取与布局无关，因此打包、非打包与混合文件加载结果一致。

 # @deepseek-ai/dsh-session-persistence-sqlite
 
 English | [中文](README.zh.md)
 
-An opt-in SQLite `SessionPersistence` provider. It stores eligible `assistant/chunk` runs in packed physical rows, selectively Zstandard-compresses large payloads, and delta-encodes provenance sequences while restoring the exact logical `SessionEvent[]`. No shipped composition selects it; deployments mount this package explicitly and provide its database path.
+## Summary
 
-`locate(meta)` returns `undefined` because every session shares one database. The provider exposes no per-session raw artifact.
+`dsh-session-persistence-sqlite` keeps every session's durable history in a single SQLite database: sessions survive restarts, and the deployment's whole history becomes one queryable file you can back up, inspect with SQL, and analyze — instead of one artifact per session. Choosing it changes nothing for the agent loop, the model, or replay, because it serves the same logical `SessionEvent` stream as the JSONL backend; packing, compression, and recovery are storage-internal details. Choose it when a single queryable database fits the deployment; no shipped composition enables it by default. It is a pre-release provider: it rejects database files it does not own instead of migrating them, and its synchronous Node SQLite driver blocks the JavaScript thread during reads and writes. Setup, sizing, and migration guidance come first; the implementation internals live in a collapsible developer section below.
 
-## Storage model
+## Table of Contents
 
-Schema 17 keeps ordinary ROWID tables and the composite `events(session_id, seq)` primary-key index. Scalar rows store one logical event. Packed rows use `text-chunks`, `reasoning-chunks`, or `tool-call-chunks` as the physical `type`; `seq` and `time` identify the first represented event, and `data` holds the shared packed-chunk payload. Packed rows set `ignorable=0` as a physical discriminator and leave `source_event_seqs` and `surface_op` as `NULL`; scalar rows use `ignorable=1` only for logical ignorable events and `NULL` otherwise. A future ignorable logical event may therefore reuse a storage-tag name without being decoded as a packed row. These tags are storage records, not `SessionEventMap` members.

+- [Understand the implementation](#understand-the-implementation)
+- [Further Exploration](#further-exploration)
+- [Model Experience](#model-experience)
+- [Known Limitations and Deferred Work](#known-limitations-and-deferred-work)
+- [Dev Note](#dev-note)
 
-Schema 17 owns its codec locally rather than importing another persistence format's mutable implementation. Only exact, consecutive same-block text, reasoning, or tool-call delta forms pack. Unknown fields, surface metadata, sequence gaps, incompatible block/call identity, and unsafe timestamps remain scalar. A packed row represents at most 1,024 events and at most 1 MiB of uncompressed UTF-8 `data`; longer runs are partitioned without changing logical events. Reads reconstruct every original sequence number, timestamp, token boundary, argument fragment, and payload before returning data to the persistence coordinator.
+-----
 
-Serialized `data` smaller than 4 KiB stays as SQLite `TEXT`. At or above that threshold, the writer uses Zstandard level 3 and stores a `BLOB` only when the frame is smaller than the original text; the reader decompresses it before UTF-8 validation and JSON parsing. `source_event_seqs` remains the complete ordered provenance array. Its first sequence is an unsigned varint and each subsequent sequence is a signed delta encoded with ZigZag varints, stored as a `BLOB`; no source is omitted or converted to a range.
+<a id="use-this-package"></a>
+## Use this package
 
-Each append holds `BEGIN IMMEDIATE`, validates the bounded physical tail, packs only the new durable batch, inserts those records, and increments the session revision once. Normal appends never delete or replace an earlier event row. The default 200 ms write-behind window therefore compresses high-frequency streams while the physical write volume stays proportional to newly durable batches rather than repeatedly rewriting a growing packed value. A storage-level logical-tail check rejects a stale writer before mutation.
+Mount this provider when a composition needs durable sessions backed by SQLite and accepts a process-local, synchronous database driver. The common path is explicit: load the session service, mount the provider, and give it a database path.
 
-Full reads scan physical rows in first-logical-sequence order. A reverse pass finds the last valid `turn/end` without retaining decoded copies of every physical row; the forward pass decodes and validates one physical row at a time into the returned logical event array. `readFrom(id, fromSeq)` examines packed predecessors only within the maximum row span and anchors the suffix at the earliest one that may contain `fromSeq`; this includes an event range that starts inside a packed row, detects overlapping physical corruption, and does not parse unrelated earlier scalar rows. A malformed packed row is all-or-nothing: committed corruption rejects, while a torn final row is deleted from its physical base during mutating recovery. Repair re-reads the tail under the write lock and rejects a stale marker before deleting anything. Packed `data` that exceeds the schema byte limit rejects before JSON parsing.
+### When to choose it
 
-## Schema compatibility
+Choose this backend when a local deployment benefits from one queryable database instead of many per-session files. Choose the JSONL backend when consumers need a per-session artifact: this provider returns `undefined` from `locate(meta)`, supports no raw artifacts, and exposes no per-session file. Account for synchronous SQLite and compression work before adopting it for a high-concurrency service.
 
-A pristine database initializes directly at schema 17. Older schemas, foreign application identities, non-pristine unversioned databases, and incompatible schema objects reject; this pre-release provider supplies no migration. Every statement and fixed pragma lives in a packaged `.sql` resource; values use SQLite parameters and runtime code never assembles query text.
+### Disk footprint and performance
 
-## Configuration (schemastery)
+The packed layout trades disk space for speed and structure. On the benchmark corpus behind schema 17 — 105 sessions, about 2.5 million events — the SQLite database used 75 MB against 31 MB for the default compressed JSONL logs: roughly 2.5× the on-disk size.
 
-```ts
-interface Config {
-  path: string
-  journalMode?: 'wal' | 'delete' | 'truncate' | 'persist'
-  busyTimeoutMs?: number
-  preparedSessionCacheSize?: number
-  writeBatchMaxDelayMs?: number
-}
+The same measurements show writes finishing about 3× faster, 50-event suffix reads about 40× faster, full-session reads comparable or slightly faster, and about 2.5 million physical rows shrinking to roughly 66 thousand. Expect 2–3× the compressed JSONL footprint depending on session content; the full numbers and method live in the [SQLite physical chunk-row decision](../../../.agents/notes/implemented/architecture/2026-08-18-sqlite-physical-chunk-row-compression.md).
+
+The disk cost buys a structured, queryable view of session history: external tooling can analyze `sessions` and `events` with SQL, decoding physical rows the way this provider does — the groundwork for features such as built-in full-text search.
+
+### Minimal configuration
+
+Load the session service first, then mount the provider with a database path. Use an absolute path when the location must not depend on the process working directory; relative paths resolve from that directory. `:memory:` is valid for an in-process database whose contents disappear with the process.
+
+```yaml
+- name: '@deepseek-ai/dsh-session'
+- name: '@deepseek-ai/dsh-session-persistence-sqlite'
+  config:
+    path: /absolute/path/to/sessions.db
 ```
 
-`journalMode` defaults to `wal`, `busyTimeoutMs` defaults to `5,000`, `preparedSessionCacheSize` defaults to `5`, and `writeBatchMaxDelayMs` defaults to `200`. The timeout bounds each synchronous SQLite lock wait. Because SQLite may return `SQLITE_BUSY` immediately while changing journal mode, cold open yields between attempts and starts no further attempt after an open-relative retry cutoff. An in-progress synchronous SQLite call may finish after that cutoff. The provider disables trusted schemas and memory-mapped I/O on every connection, then reads both settings back. The selected journal mode is also read back and must match; in-memory databases explicitly accept SQLite's `memory` result. After selecting the journal, the provider pins `synchronous=FULL` and verifies it so SQLite build defaults cannot weaken committed-append durability. On POSIX, the database parent and file must be owned by the current user, the parent must not be group/world-writable, and the file must have no group/world permissions. Symbolic links and non-regular files reject. Windows also rejects symbolic links and non-regular files, but deployments remain responsible for restricting the directory and file ACLs to the harness user. Path and ownership failures reject plugin initialization. Node SQLite loads lazily on the first persistence operation; the import suppresses only Node 22's exact SQLite `ExperimentalWarning`. Store-identity and schema failures reject that operation before data is exposed or mutated. `ensureMaterialized` inserts a metadata row with zero event rows, while ordinary `create` remains lazy until the first append.
+| Field | Default | Meaning |
+|---|---|---|
+| `path` | required | SQLite database path, or `:memory:` |
+| `journalMode` | `wal` | Durable journal mode: `wal`, `delete`, `truncate`, or `persist` |
+| `busyTimeoutMs` | `5,000` | Maximum synchronous wait for another connection's lock |
+| `preparedSessionCacheSize` | `5` | Cold session preparations retained for resume reuse |
+| `writeBatchMaxDelayMs` | `200` | Fixed live-event coalescing window, in milliseconds |
 
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-session-persistence-sqlite) is the exhaustive source for every accepted field and its JSDoc.
+
+### Migrating existing JSONL sessions
+
+There is no built-in migration tool: the JSONL and SQLite stores are separate, and nothing copies sessions between them. Because both backends implement the same logical contract, you can carry a session over with the persistence API — read on the JSONL side, write on the SQLite side. One backend serves `ctx.sessionPersistence` per composition, so run the two halves as separate runs or processes:
+
+```text
+// Export — run against the JSONL composition, per session id:
+const { meta, events } = await ctx.sessionPersistence.load(id)
+
+// Import — run against the SQLite composition, per exported session:
+await ctx.sessionPersistence.create(meta)
+await ctx.sessionPersistence.append(id, events)
+```
+
+`list()` enumerates the materialized sessions to export. The exported events keep contiguous `seq` values starting at 0, so `append` accepts them as one ordered batch into a fresh session; `load` also commits any needed cold repair on the source first, so the exported log is balanced. Treat the migration as a one-time cutover: verify that the imported sessions load, then switch the composition to the SQLite provider. Continuing to write through the old JSONL root afterwards would let the two stores diverge.
+
+### Startup and safe operation
+
+A fresh database initializes directly at schema version 17. Databases with any other version, a foreign application identity, an unversioned non-pristine schema, or unexpected schema objects are rejected before any data is exposed or changed — this pre-release provider ships no migration. Every statement and fixed pragma comes from packaged `.sql` resources in `resources/sql/`, and runtime values are bound as SQLite parameters, so package code never assembles query text.
+
+Each connection disables SQLite trusted schemas and memory-mapped I/O, verifies the requested journal mode, and pins `synchronous=FULL` so a resolved append remains durable across an OS crash or power loss. On POSIX, the database parent directory and file must belong to the current user, the parent must not be group/world-writable, and the file must grant no group or world permissions; Windows additionally rejects symbolic links and non-regular files, while ACL restriction stays the deployment's job. Path and ownership failures reject plugin initialization; Node's SQLite driver loads lazily on the first persistence operation. Ordinary `create` stays lazy until the first append, while `ensureMaterialized` writes a session metadata row with no event rows.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the provider and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The provider is built on one separation and three commitments:
+
+- **Logical contract, physical format.** Callers always read and write ordinary `SessionEvent[]`; how rows are packed, stored, and compressed is private to this package.
+- **The schema owns the format.** Schema 17 is a frozen physical contract: a database at another version, with a foreign identity, or with unexpected schema objects is rejected, never migrated. Changing the physical rules requires a new schema.
+- **Durability is the default.** Appends run in immediate transactions with `synchronous=FULL`, and a resolved `append()` means the batch is durable. Normal appends are insert-only: earlier event rows are never rewritten.
+- **Efficiency within strict bounds.** Packing and compression keep the database small, but every limit is a hard format bound — at most 1,024 events and 1 MiB of payload per packed row.
+
+The decision history — alternatives considered, measurements, and consequences — lives in the [SQLite physical chunk-row decision](../../../.agents/notes/implemented/architecture/2026-08-18-sqlite-physical-chunk-row-compression.md).
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `Config` schema, service registration, coordinator wiring |
+| [`src/store.ts`](src/store.ts) | Storage primitives: transactional append, reads, repair, path and ownership validation |
+| [`src/schema.ts`](src/schema.ts) | Schema ownership: version gate, connection hardening, row decoding |
+| [`src/codec.ts`](src/codec.ts) | Packing: which `assistant/chunk` runs become packed rows, size bounds |
+| [`src/compression.ts`](src/compression.ts) | Physical encoding: compression threshold, sequence lists, row scan and decode |
+| [`src/sql.ts`](src/sql.ts) + [`resources/sql/`](resources/sql/) | Every SQL statement as a packaged, closed-name resource |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; packing is observable only by database round-trip) |
+
+### Database schema
+
+A fresh database contains three strict tables, defined in [`resources/sql/schema.sql`](resources/sql/schema.sql):
+
+| Table | Purpose |
+|---|---|
+| `persistence_state` | One-row store identity |
+| `sessions` | One row per session: header fields plus a monotonic revision |
+| `events` | Physical event rows: one logical event, or one packed run |
+
+The exact columns live in [`resources/sql/schema.sql`](resources/sql/schema.sql). `events.data` holds text or a blob: small payloads stay text, larger ones are stored compressed when that is smaller. Packed rows reuse the `seq` of their first logical event, so under the composite `(session_id, seq)` primary key physical order is logical order.
+
+### Write path
+
+Each append takes an immediate transaction, re-validates schema ownership, checks the stored tail so a stale writer cannot extend the log, packs only the new batch, inserts its rows, bumps the session revision once, and commits. The coordinator coalesces live events for the configured window, so high-frequency streams produce larger packed runs while physical writes stay proportional to newly durable batches.
+
+### Read and recovery
+
+A full read locates the last valid `turn/end` in a reverse pass, then decodes each physical row into its logical events in forward order, rejecting gaps or malformed rows in the committed prefix. A malformed final row is treated as a torn tail: a mutating load may delete it under the write lock and close the log with synthetic closers. Suffix reads (`readFrom`) examine only the physical span that may contain the requested sequence, so they never parse unrelated earlier rows.

 ## Known Limitations and Deferred Work
 
-- **Interim SQLite-specific design** — This efficiency-focused implementation is informed by [morlay/session-persistence-rdb](https://github.com/morlay/session-persistence-rdb). A unified relational-database design with multiple backends and configurable schemas is deferred; neither schema stability nor migration support is guaranteed during pre-release development.
-- **Packing follows durable batch boundaries** — compatible runs split by the write-behind window or an explicit flush remain separate physical records; this avoids rewriting prior rows at the cost of a timing-dependent packing ratio.
-- **Synchronous compression** — Node's SQLite and Zstandard calls block the JavaScript thread; the 4 KiB threshold limits per-frame work for small records.
-- **`DatabaseSync` blocks the event loop** — physical row reduction does not make SQLite operations asynchronous.
-- **Busy waits block the event loop** — SQLite waits inside synchronous `DatabaseSync` calls; only a busy journal-mode transition yields between attempts, and the open-relative cutoff prevents another attempt rather than interrupting an active call.
-- **External SQL readers must understand physical tags** — supported consumers read through this provider rather than treating every `events.type` as a logical event type.
-- **No deletion or background historical compaction** — normal appends are insert-only.
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define when the provider is a poor fit or needs special operational care. They are current package constraints, not a general SQLite comparison or a task backlog.
+
+- **Pre-release design with no migration** — schema 17 is an interim SQLite-only design; the deferred unified multi-backend relational design with configurable schemas exists as a working external prototype in [morlay/session-persistence-rdb](https://github.com/morlay/session-persistence-rdb) (Drizzle-based, SQLite and PostgreSQL), and neither schema stability nor migration support is guaranteed.
+- **Packing depends on batch boundaries** — a compatible run split by the write-behind window or an explicit flush stays split across physical rows; this avoids rewriting prior rows at the cost of a timing-dependent packing ratio.
+- **Synchronous SQLite and compression** — Node's SQLite driver and Zstandard calls block the JavaScript thread; the 4 KiB compression threshold bounds per-frame work for small records.
+- **Busy waits block the event loop** — SQLite waits inside synchronous calls; a competing writer can stall the thread for up to the configured `busyTimeoutMs`.
+- **External SQL readers must decode physical rows** — a packed `events.type` (`text-chunks`, `reasoning-chunks`, `tool-call-chunks`) is not a logical event type; supported consumers read through this provider.
+- **No deletion or historical compaction** — normal appends are insert-only and nothing removes old rows.

+### Dev Note
+
+<details>
+<summary>Working context for maintainers — click to expand</summary>
+
+This Dev Note is working context for maintainers: measured artifacts, open design questions, and directions that are not decided. It is explicitly non-authoritative — shipped behavior, limits, and accepted rationale live in the sections above, the package code, and the linked Agent Notes, and conclusions migrate there once they stabilize.
+
+#### Benchmark artifact
+
+The numbers below are the benchmark behind schema 17; the [SQLite physical chunk-row decision](../../../.agents/notes/implemented/architecture/2026-08-18-sqlite-physical-chunk-row-compression.md) is the authoritative record, and this table is an annotated digest.
+
+| Metric | **JSONL (zstd)** | **SQLite (legacy)** | **SQLite (new)** |
+|---|---|---|---|
+| On-disk size | **30.65 MB** | 709.57 MB | 75.01 MB |
+| Write time, 105 sessions | 28.21 s | 10.64 s | **8.58 s** |
+| Complete-session read p50 / p95 | 4.49 / 23.36 ms | 9.02 / 69.16 ms | **3.95 / 21.58 ms** |
+| 50-event tail read p50 / p95 | 10.58 / 80.90 ms | **0.189 / 0.293 ms** | 0.253 / 0.378 ms |
+| Event rows | 2,507,860 (logical) | 2,507,860 | **65,810** |
+| Fork of all sessions | 14.48 s | 19.30 s | **13.10 s** |
+
+The corpus was 105 sessions with 2,507,860 logical events appended in 512-event durable batches, so the ratios depend on session content, stream density, and batch boundaries. `SQLite (legacy)` is the scalar layout — one physical row per logical event, no packing — whose 709.57 MB footprint motivated the packed rows. Against JSONL, schema 17 uses ≈2.5× the disk space but writes ≈3.3× faster, reads complete sessions faster at both percentiles, and reads 50-event tails ≈40× faster; against the scalar layout it is ≈89% smaller, faster to write, and shrinks 2,507,860 rows to 65,810, while scalar tail reads remain marginally faster (0.189 vs 0.253 ms p50). Re-run or extend this benchmark whenever the write path or the schema changes.
+
+#### Future: multi-backend RDB persistence (Drizzle)
+
+A unified multi-backend relational design stays deferred. A Drizzle-backed rework would need to resolve: schema ownership — the per-version freeze and exact-object validation exist so any composition can read any same-version database, so a customizable schema must remain versioned and validated the same way; backend hardening — `synchronous=FULL`, busy timeout, and ownership checks are SQLite-specific, and Postgres or MySQL backends need their own durability and permission story; and codec portability — the packed-row codec is shaped around SQLite columns, so either a shared codec across dialects or per-backend codecs fixed by schema version must keep the logical contract identical.
+
+#### Future: persistence-to-persistence transfer and version migration
+
+The README documents a manual `load` → `create`/`append` transfer, but the seam has no import/export API, and SQLite rejects other schema versions outright. Automating transfer needs: an export format that preserves header lineage (`seedLength`, `parentSession`, `agentPreset`) and revision semantics; an upgrader chain for format and schema versions, the deferred chain from the [session-log-version-mechanism note](../../../.agents/notes/implemented/architecture/2026-08-10-session-log-version-mechanism.md); and a source-side guarantee that the log is readable and balanced before export — `load` already commits cold repair.
+
+#### Future: in-database full-text search and indexing
+
+The sibling [session-query-sqlite](../../session-query/session-query-sqlite/README.md) package already maintains a dedicated SQLite FTS5 search index over session content in a separate derived-index database. Putting FTS inside the persistence database would duplicate that surface; open questions are where the index belongs, how to keep it transactional with append, and whether packed rows should be expanded into index documents or the index should read the logical stream. The persistence schema currently indexes only `(session_id, seq)`; further indexes (for example on `sessions.created_at` for cold-cutoff scans) are easy but add write cost.
+
+#### Future: cold-data offloading to cascaded database files
+
+The provider has no deletion or background compaction: everything stays in one database forever. One direction is offloading cold sessions (for example, older than 30 days) into separate archive database files arranged as a cascade, with more aggressive compression — a higher Zstandard level is cheap for cold data. That needs: a routing rule that knows which file holds which session, cross-file fan-out for `list`/`readFrom`/`load`, consistent revisions and store identity across the cascade, and a decision on whether offloading replaces the no-deletion limit or supplements it.

-一个可选启用的 SQLite `SessionPersistence` 提供方。它将符合条件的 `assistant/chunk` 连续段存入打包后的物理行，对大型 payload 选择性应用 Zstandard 压缩，并对来源序列进行 delta 编码，同时恢复完全一致的逻辑 `SessionEvent[]`。随产品交付的组合均不选择它；部署方需显式挂载本包并提供数据库路径。
+## 概述
 
-`locate(meta)` 返回 `undefined`，因为所有会话共享同一个数据库。该提供方不暴露逐会话原始产物。
+`dsh-session-persistence-sqlite` 是 `SessionPersistence` 服务的可选存储后端：它不按会话各留一个文件，而是把所有会话的持久事件日志统一保存在同一个 SQLite 数据库中。它与 JSONL 后端提供完全相同的逻辑 `SessionEvent` 流，因此选择它不会改变 agent loop、模型或回放的任何行为——打包、压缩与恢复都是存储内部细节。仅当单一可查询数据库适合你的部署时才选择它；任何已发布的组合都不会默认启用它。这是预发布提供方：它拒绝而非迁移不属于自己的数据库文件，而且其同步 Node SQLite 驱动会在读写时阻塞 JavaScript 线程。设置、容量评估与迁移指引在前；实现内部细节放在下方可折叠的开发者章节中。
 
-## 存储模型
+## 目录
 
-Schema 17 保留普通 ROWID 表以及复合主键索引 `events(session_id, seq)`。标量行存储一个逻辑事件。打包行把 `text-chunks`、`reasoning-chunks` 或 `tool-call-chunks` 用作物理 `type`；`seq` 与 `time` 标识所表示的第一个事件，`data` 保存共享的分片打包 payload。打包行把 `ignorable=0` 用作物理判别值，并让 `source_event_seqs` 与 `surface_op` 保持 `NULL`；标量行仅在逻辑事件可忽略时使用 `ignorable=1`，否则使用 `NULL`。因此，未来的可忽略逻辑事件即使复用了某个存储标签名称，也不会被解码为打包行。这些标签属于存储记录，而不是 `SessionEventMap` 成员。

+- [已知限制与延期工作](#known-limitations-and-deferred-work)
+- [开发备注](#dev-note)
 
-Schema 17 在本包内拥有 codec，不导入其他持久化格式中可变的实现。只有字段完全匹配、连续且属于同一分片块的文本、推理或工具调用 delta 才会打包。未知字段、surface 元数据、序列缺口、不兼容的块／调用身份以及不安全时间戳仍以标量行存储。一个打包行最多表示 1,024 个事件，未压缩 UTF-8 `data` 最多 1 MiB；更长的连续段会在不改变逻辑事件的前提下分割。读取会在向持久化协调器返回数据前，重建每个原始序列号、时间戳、token 边界、参数片段和 payload。
+-----
 
-序列化后的 `data` 小于 4 KiB 时保持为 SQLite `TEXT`。达到或超过该阈值时，写入方会使用 Zstandard level 3，并且只在 frame 小于原文本的情况下存储 `BLOB`；读取方会先解压，再执行 UTF-8 校验和 JSON 解析。`source_event_seqs` 仍是完整且有序的来源数组。第一个序列使用无符号 varint，后续序列使用 ZigZag varint 编码的有符号差值，并存为 `BLOB`；不会省略任何来源，也不会把数组转换成范围。
+<a id="use-this-package"></a>
+## 使用本包
 
-每次追加持有 `BEGIN IMMEDIATE`，验证有界物理尾部，只打包新的持久批次，插入这些记录，并把会话 revision 递增一次。普通追加绝不删除或替换既有事件行。默认 200 毫秒写后缓冲窗口因此仍能压缩高频流，而物理写入量与新增持久批次成正比，不会反复改写不断增长的打包值。存储层逻辑尾部检查会在陈旧写入方执行变更前拒绝该写入。
+当组合需要由 SQLite 支撑的持久会话、且可以接受进程本地的同步数据库驱动时，挂载此提供方。常用路径是显式的：加载会话服务、挂载提供方，然后给出数据库路径。
 
-完整读取按首个逻辑序列号的顺序扫描物理行。反向扫描会定位最后一个有效 `turn/end`，但不会保留每个物理行的解码副本；正向扫描则逐行解码并校验，写入最终返回的逻辑事件数组。`readFrom(id, fromSeq)` 只检查最大行跨度内的打包前驱，并把后缀锚定在可能包含 `fromSeq` 的最早前驱；这样既可包含从打包行内部开始的事件范围，也能检测相互重叠的物理损坏，而不会解析无关的更早标量行。畸形打包行按全有或全无处理：已提交区域中的损坏会拒绝读取，最终撕裂行则在可变恢复期间从其物理起点删除。修复会在持有写锁时重新读取尾部，并在删除任何数据前拒绝陈旧 marker。打包 `data` 超出 schema 字节上限时，会在解析 JSON 前拒绝。
+### 何时选择
 
-## Schema 兼容性
+当本地部署受益于一个可查询数据库、而非每会话一个独立文件时，选择此后端。当消费方需要按会话产物时，请选择 JSONL 后端：本提供方的 `locate(meta)` 返回 `undefined`，不支持原始产物，也不暴露任何单会话文件。高并发服务在采用前还应考虑同步 SQLite 与压缩工作。
 
-全新数据库直接初始化为 schema 17。旧 schema、外部 application identity、非空未版本化数据库以及不兼容 schema 对象都会被拒绝；这个预发布提供方不提供迁移。每条语句和固定 pragma 都位于随包发布的 `.sql` 资源中；值使用 SQLite 参数，运行时代码不会拼装查询文本。
+### 磁盘占用与性能
 
-## 配置（schemastery）
+打包布局以磁盘空间换取速度与结构。在 schema 17 的基准语料上——105 个会话、约 250 万个事件——SQLite 数据库占用 75 MB，而默认压缩 JSONL 日志为 31 MB：磁盘占用约为后者的 2.5 倍。
 
-```ts
-interface Config {
-  path: string
-  journalMode?: 'wal' | 'delete' | 'truncate' | 'persist'
-  busyTimeoutMs?: number
-  preparedSessionCacheSize?: number
-  writeBatchMaxDelayMs?: number
-}
+同一组测量显示，写入快约 3 倍，50 个事件的后缀读取快约 40 倍，完整会话读取相当或略快，约 250 万个物理行缩减到约 6.6 万个。按会话内容不同，磁盘占用约为压缩 JSONL 的 2–3 倍；完整数据与方法见 [SQLite 物理分片行决策](../../../.agents/notes/implemented/architecture/2026-08-18-sqlite-physical-chunk-row-compression.zh.md)。
+
+磁盘成本换来的是结构化、可查询的会话历史视图：外部工具可以用 SQL 分析 `sessions` 与 `events`，按本提供方的方式解码物理行——这是内置全文搜索等功能的天然基础。
+
+### 最小配置
+
+先加载会话服务，再用数据库路径挂载提供方。除非位置允许依赖进程工作目录（相对路径从该目录解析），否则请使用绝对路径。`:memory:` 可用于进程内数据库，其内容随进程消失。
+
+```yaml
+- name: '@deepseek-ai/dsh-session'
+- name: '@deepseek-ai/dsh-session-persistence-sqlite'
+  config:
+    path: /absolute/path/to/sessions.db
 ```
 
-`journalMode` 默认为 `wal`，`busyTimeoutMs` 默认为 `5,000`，`preparedSessionCacheSize` 默认为 `5`，`writeBatchMaxDelayMs` 默认为 `200`。该超时限制每次同步 SQLite 锁等待的时长。SQLite 在切换 journal mode 时可能立即返回 `SQLITE_BUSY`，因此冷打开会在尝试之间让出执行，并在从打开时开始计算的重试截止点后不再发起新尝试。正在执行的同步 SQLite 调用可能在该截止点之后才完成。提供方会在每个连接上禁用可信 schema 与内存映射 I/O，然后读回这两项设置。提供方还会读回所选 journal mode 并要求它匹配；内存数据库显式接受 SQLite 返回的 `memory`。选择 journal 后，提供方会把 `synchronous` 固定为 `FULL` 并验证该设置，避免 SQLite 构建默认值削弱已提交追加的持久性。在 POSIX 上，数据库父目录和文件必须归当前用户所有，父目录不得允许组或其他用户写入，文件不得授予组或其他用户任何权限。符号链接和非普通文件会被拒绝。Windows 同样拒绝符号链接与非普通文件，但部署方仍负责把目录和文件 ACL 限制给 harness 用户。路径与所有权错误会拒绝插件初始化。Node SQLite 在第一次持久化操作时才加载；导入时只抑制 Node 22 精确的 SQLite `ExperimentalWarning`。存储身份与 schema 错误会在暴露或变更数据前拒绝该操作。`ensureMaterialized` 会插入零事件行的元数据行；普通 `create` 仍保持惰性，直到第一次 append。
+| 字段 | 默认值 | 含义 |

+
+### 迁移现有 JSONL 会话
+
+没有内置迁移工具：JSONL 与 SQLite 是两个独立存储，没有任何机制在两者之间复制会话。由于两个后端实现相同的逻辑约定，你可以直接用持久化 API 迁移会话——在 JSONL 侧读取，在 SQLite 侧写入。每个组合只有一个后端服务于 `ctx.sessionPersistence`，因此两步请分两次运行或分两个进程执行：
+
+```text
+// Export — run against the JSONL composition, per session id:
+const { meta, events } = await ctx.sessionPersistence.load(id)
+
+// Import — run against the SQLite composition, per exported session:
+await ctx.sessionPersistence.create(meta)
+await ctx.sessionPersistence.append(id, events)
+```
+
+用 `list()` 枚举已物化的会话。导出的事件 `seq` 从 0 开始连续，因此 `append` 可以一次性按序写入新会话；`load` 会先在源端提交所需的冷修复，导出的日志因此是平衡的。请把迁移当作一次性切换：确认导入的会话可以加载后，再把组合切换到 SQLite 提供方；之后继续写旧 JSONL 根目录会让两个存储分叉。
+
+### 启动与安全运行
+
+全新数据库直接初始化为 schema 版本 17。任何其他版本、外来应用标识、无版本的非全新 schema 或意外 schema 对象，都会在任何数据暴露或变更之前被拒绝——本预发布提供方不提供迁移。每条语句和固定 pragma 都来自 `resources/sql/` 下打包的 `.sql` 资源，运行时的值以 SQLite 参数绑定，包代码从不拼装查询文本。
+
+每个连接都会禁用 SQLite trusted schema 与内存映射 I/O、验证所请求的 journal mode，并固定 `synchronous=FULL`，保证成功返回的追加在操作系统崩溃或断电后依然持久。在 POSIX 上，数据库父目录和文件必须属于当前用户，父目录不得允许组或其他用户写入，文件也不得授予任何组或其他用户权限；Windows 还会拒绝符号链接和非普通文件，ACL 限制则由部署方负责。路径与所有权失败会拒绝插件初始化；Node 的 SQLite 驱动在首次持久化操作时才延迟加载。普通 `create` 会保持惰性直到首次 append，而 `ensureMaterialized` 会写入一条没有事件行的会话元数据记录。

+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释提供方背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+本提供方建立在一个分离与三项承诺之上：
+
+- **逻辑约定，物理格式。** 调用方始终读写普通的 `SessionEvent[]`；行如何打包、存储与压缩是本包私有的存储行为。
+- **schema 拥有格式。** Schema 17 是冻结的物理约定：任何其他版本、外来标识或意外 schema 对象的数据库都会被拒绝，绝不迁移。改变物理规则需要新的 schema。
+- **持久性是默认值。** 追加在立即事务中以 `synchronous=FULL` 提交，成功返回的 `append()` 意味着该批次已持久。普通追加仅插入：更早的事件行永远不会被重写。
+- **在严格边界内追求效率。** 打包与压缩让数据库保持小巧，但每个上限都是硬性格式边界——每个打包行至多表示 1,024 个事件、1 MiB 载荷。
+
+决策历史——备选方案、测量数据与后果——记录在 [SQLite 物理分片行决策](../../../.agents/notes/implemented/architecture/2026-08-18-sqlite-physical-chunk-row-compression.zh.md) 中。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：`Config` schema、服务注册、协调器接线 |
+| [`src/store.ts`](src/store.ts) | 存储原语：事务追加、读取、修复、路径与所有权验证 |
+| [`src/schema.ts`](src/schema.ts) | schema 归属：版本门禁、连接加固、行解码 |
+| [`src/codec.ts`](src/codec.ts) | 打包：哪些 `assistant/chunk` 连续段成为打包行、大小上限 |
+| [`src/compression.ts`](src/compression.ts) | 物理编码：压缩阈值、序列列表、行扫描与解码 |

+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；打包只能通过数据库往返观察） |
+
+### 数据库 schema
+
+全新数据库包含三张 STRICT 表，定义于 [`resources/sql/schema.sql`](resources/sql/schema.sql)：
+
+| 表 | 用途 |
+|---|---|
+| `persistence_state` | 单行存储标识 |
+| `sessions` | 每个会话一行：头部字段加单调递增的 revision |
+| `events` | 物理事件行：一个逻辑事件，或一个打包连续段 |
+
+确切的列定义见 [`resources/sql/schema.sql`](resources/sql/schema.sql)。`events.data` 列存放文本或 blob：小载荷保持为文本，较大的载荷在压缩后更小时以压缩形式存储。打包行沿用其首个逻辑事件的 `seq`，因此在复合主键 `(session_id, seq)` 下，物理顺序就是逻辑顺序。
+
+### 写入路径
+
+每次追加都会开启立即事务、重新验证 schema 归属、检查已存尾部以防止陈旧写入方扩展日志、只打包新批次、插入对应行、递增一次会话 revision，然后提交。协调器按配置窗口聚合实时事件，因此高频流会产生更大的打包行，而物理写入量始终与新持久批次成正比。
+
+### 读取与恢复
+
+完整读取先反向定位最后一个有效 `turn/end`，再按正向顺序把每个物理行解码为其逻辑事件，并拒绝已提交前缀中的缺口或格式错误行。格式错误的最后一行被视为撕裂尾部：执行恢复的加载可以在写锁下删除它，并用合成闭合事件关闭日志。后缀读取（`readFrom`）只检查可能包含目标序列的物理跨度，因此永远不会解析无关的更早行。

 ## 已知限制与延期工作
 
-- **过渡性的 SQLite 专用设计**——这一以效率为重点的实现参考了 [morlay/session-persistence-rdb](https://github.com/morlay/session-persistence-rdb)。支持多种后端与可配置 schema 的统一关系数据库设计尚待后续完善；预发布开发阶段不保证 schema 稳定性或迁移支持。
-- **打包服从持久批次边界**——被写后缓冲窗口或显式 flush 分开的兼容连续段会保留为不同物理记录；这以打包率受时序影响为代价，避免改写既有行。
-- **同步压缩**——Node 的 SQLite 与 Zstandard 调用都会阻塞 JavaScript 线程；4 KiB 阈值限制了小型记录的逐 frame 工作。
-- **`DatabaseSync` 会阻塞事件循环**——减少物理行不会使 SQLite 操作变为异步。
-- **繁忙等待会阻塞事件循环**——SQLite 会在同步 `DatabaseSync` 调用内等待；只有繁忙的 journal-mode 切换会在两次尝试之间让出执行，而且从打开时计算的截止点只阻止新尝试，不会中断正在执行的调用。
-- **外部 SQL 读取方必须理解物理标签**——受支持的消费方通过本提供方读取，而不是把每个 `events.type` 都当作逻辑事件类型。
-- **没有删除或后台历史压缩**——普通追加只做插入。
+<a id="known-limitations-and-deferred-work"></a>
+
+
+这些限制说明本提供方何时不合适，或何时需要特别的运维注意。它们是当前包约束，不是通用 SQLite 对比或任务积压。
+
+- **预发布设计，无迁移**——schema 17 是临时的 SQLite 专用设计；被推迟的统一多后端、可配置 schema 关系型设计已有可运行的外部原型 [morlay/session-persistence-rdb](https://github.com/morlay/session-persistence-rdb)（基于 Drizzle，支持 SQLite 与 PostgreSQL），预发布期间不保证 schema 稳定性或迁移支持。
+- **打包依赖批次边界**——被写后窗口或显式 flush 拆开的兼容连续段仍分属不同物理行；这避免了重写先前行，代价是打包比例依赖时序。
+- **同步 SQLite 与压缩**——Node 的 SQLite 驱动与 Zstandard 调用会阻塞 JavaScript 线程；4 KiB 压缩阈值限制了小记录的单帧工作量。
+- **忙等待阻塞事件循环**——SQLite 在同步调用内部等待；竞争写入方最长可让线程停顿配置的 `busyTimeoutMs`。
+- **外部 SQL 读取方必须解码物理行**——打包的 `events.type`（`text-chunks`、`reasoning-chunks`、`tool-call-chunks`）不是逻辑事件类型；受支持的消费方通过本提供方读取。
+- **没有删除或历史压缩**——普通追加仅插入，没有任何机制移除旧行。

+
+<details>
+<summary>维护者的工作上下文——点击展开</summary>
+
+本开发备注是维护者的工作上下文：测量产物、开放设计问题与尚未决定的探索方向。它明确不具权威性——已交付的行为、限制与既定理由以上文、包代码和相关 Agent Note 为准，结论一旦稳定就迁移到对应归属。
+
+#### 基准产物
+
+以下数字是 schema 17 背后的基准；[SQLite 物理分片行决策](../../../.agents/notes/implemented/architecture/2026-08-18-sqlite-physical-chunk-row-compression.zh.md) 是权威记录，本表只是带注的摘要。
+
+| 指标 | **JSONL（zstd）** | **SQLite（legacy）** | **SQLite（new）** |
+|---|---|---|---|
+| 磁盘占用 | **30.65 MB** | 709.57 MB | 75.01 MB |
+| 105 个会话的写入时间 | 28.21 s | 10.64 s | **8.58 s** |
+| 完整会话读取 p50 / p95 | 4.49 / 23.36 ms | 9.02 / 69.16 ms | **3.95 / 21.58 ms** |
+| 50 个事件尾部读取 p50 / p95 | 10.58 / 80.90 ms | **0.189 / 0.293 ms** | 0.253 / 0.378 ms |
+| 事件行数 | 2,507,860（逻辑） | 2,507,860 | **65,810** |
+| 全部会话 fork | 14.48 s | 19.30 s | **13.10 s** |
+
+语料为 105 个会话、2,507,860 个逻辑事件，按 512 个事件一批追加，因此具体比例取决于会话内容、流密度与批次边界。`SQLite（legacy）` 是标量布局——每个逻辑事件一行、不打包——其 709.57 MB 的占用正是打包行的动机。相对 JSONL，schema 17 磁盘占用约为 2.5 倍，但写入快约 3.3 倍，完整会话读取在两个分位上都更快，50 个事件尾部读取快约 40 倍；相对标量布局，它缩小约 89%、写入更快，并把 2,507,860 行缩减到 65,810 行，只有标量尾部读取仍略快（0.189 对 0.253 ms p50）。写入路径或 schema 变化时，请重跑或扩展该基准。
+
+#### 未来：多后端 RDB 持久化（Drizzle）
+
+统一的多后端关系型设计仍被推迟。若以 Drizzle 实现，需要解决：schema 归属——逐版本冻结与精确对象校验的意义在于任何组合都能读取同版本数据库，可定制 schema 必须同样带版本并接受同样校验；后端加固——`synchronous=FULL`、busy timeout 与所有权检查都是 SQLite 专属，Postgres 或 MySQL 后端需要各自的持久性与权限方案；codec 可移植性——打包 codec 围绕 SQLite 列设计，无论跨方言共享 codec 还是按 schema 版本固定每后端 codec，都必须保持逻辑约定完全一致。
+
+#### 未来：持久化到持久化的迁移与版本升级
+
+README 记录了手动的 `load` → `create`/`append` 迁移，但 seam 没有导入/导出 API，SQLite 也直接拒绝其他 schema 版本。自动化迁移需要：能保留头部血缘（`seedLength`、`parentSession`、`agentPreset`）与 revision 语义的导出格式；格式与 schema 版本的升级链，即 [session-log-version-mechanism 笔记](../../../.agents/notes/implemented/architecture/2026-08-10-session-log-version-mechanism.zh.md) 中推迟的升级链；以及导出前源日志可读且平衡的保证——`load` 已先提交冷修复。
+
+#### 未来：库内全文搜索与索引改进
+
+兄弟包 [session-query-sqlite](../../session-query/session-query-sqlite/README.zh.md) 已经在独立派生索引数据库中维护一份会话内容的 SQLite FTS5 搜索索引。把 FTS 放进持久化数据库会重复该表面；开放问题包括索引归属、如何与追加保持事务一致，以及打包行应展开成索引文档还是索引直接读取逻辑流。持久化 schema 目前只索引 `(session_id, seq)`；额外索引（例如 `sessions.created_at` 用于冷数据截止扫描）实现简单，但会增加写入成本。
+
+#### 未来：冷数据卸载到级联数据库文件
+
+本提供方没有删除或后台压缩：所有数据永远留在同一个数据库里。一个方向是把冷会话（例如超过 30 天）卸载到按级联组织的独立归档数据库文件，并对冷文件使用更激进的压缩——对冷数据而言，更高的 Zstandard 级别代价很低。这需要：知道哪个文件存放哪个会话的路由规则、`list`/`readFrom`/`load` 的跨文件扇出、级联间一致的 revision 与存储标识，以及卸载是取代还是补充「无删除」限制的决定。

-Session persistence is a capability seam. The abstract `SessionPersistence` service (`ctx.sessionPersistence`) is its Service Definition. It requires a persistence backend to store, reload, and list sessions durably without defining the storage implementation. The seam follows the `dsh-shell` roles ([capability seams](../../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.md)): this package owns the Service Definition, a sibling package owns the Service Provider, and Consumers inject the service.
+## Summary
 
-The persisted unit IS the existing `SessionEvent` (event-sourced model — the log is the single source of truth), so there is no parallel "persisted message" type. Metadata that is NOT replayable conversation state (format version, cwd, lineage, seed boundary, origin, delegation depth) travels separately as `SessionHeader`, owned by `dsh-session` and re-exported here.
+`dsh-session-persistence` stores a session's event log durably, reloads it on resume, and lists stored sessions through one backend-neutral service (`ctx.sessionPersistence`) that every persistence backend implements. The persisted unit is the existing `SessionEvent` log — there is no parallel stored message type — and non-replayable metadata (format version, working directory, lineage, seed boundary) travels separately as `SessionHeader`. Backends own their storage, the service owns the semantics: append-only logs, contiguous sequence numbers, crash recovery that preserves an interrupted turn instead of truncating it, and durable writes that resolve only after the batch is safe. Pick a backend (`session-persistence-jsonl` for per-session files, `session-persistence-sqlite` for one database), mount it, and sessions persist and resume without the loop or the model knowing which backend is underneath.

+## Use this package
+
+Mount one persistence backend to make sessions durable. The backend registers itself as `ctx.sessionPersistence`; nothing else in the composition changes — the loop, resume, and replay all call the same service.
+
+### Choosing a backend
+
+The seam ships two interchangeable backends. Choose [JSONL](../session-persistence-jsonl/README.md) when each session should live in its own on-disk artifact: it stores one append-only `.jsonl.zstd` log per session and returns an absolute artifact path from `locate(meta)`. Choose [SQLite](../session-persistence-sqlite/README.md) when one queryable database fits the deployment: it keeps every session's log in a single database with packed physical rows and returns no per-session artifact. A third-party backend may implement the service directly; the [backend contract](#understand-the-implementation) below is what it must honor.
+
+### What the service provides
+
+With a backend mounted, you can store a session's events durably, reload the stored log, and list what is stored:
+
+```text
+await ctx.sessionPersistence.create(meta)                  // register a session
+await ctx.sessionPersistence.ensureMaterialized(session)   // persist an empty resumable session
+await ctx.sessionPersistence.append(id, events)            // durably persist a batch
+const { meta, events } = await ctx.sessionPersistence.load(id)   // reload on resume
+const headers = await ctx.sessionPersistence.list()        // every stored session
+```
+
+`append` resolves only after the batch is durable, so a resolved write survives an OS crash or power loss. Ordinary `create` remains lazy; a lifecycle frontend calls `ensureMaterialized` only when an empty session must itself appear in durable listing without inventing an event. `load` returns an immutable balanced log and commits any needed crash recovery; `inspect` reads the same view without committing recovery. Consumers that resume from a watermark can read only the events at or past a sequence number, and a session's artifact location (`locate`) resolves without filesystem I/O.
+
+### Resuming and crash recovery
+
+Resume is `load` plus session preparation: the stored log comes back with its header lineage intact, so a resumed agent sees the same history and composition. A session that crashed mid-turn reloads with its interrupted final turn preserved and balanced: `load` appends synthetic `tool/result` and `turn/end {interrupted}` closers for unanswered calls instead of dropping the events — a single turn can be large, and those events were durably written before the crash. Only a never-fully-written torn tail fragment is discarded.
+
+### Failures and recovery
+
+A stored log the current build cannot faithfully interpret is refused with a direction-aware error, never misread. `SESSION_FORMAT_VERSION` remains v0 and this build provides no format-migration path; a newer version instructs the operator to upgrade the harness. The decoder accepts only the bounded same-version record variants named below. An event type unknown to this build refuses unless its envelope marks it `ignorable`, and committed-prefix corruption rejects as `SessionPersistenceCorruptionError`. A `load` on an id still bound to a live session first flushes its snapshot and rejects while its turn is open; a cold load applies recovery.
+

+<a id="understand-the-implementation"></a>
+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the seam realizes durable storage and how backends plug in; the observable contract is covered in [Use this package](#use-this-package) and the generated [Cordis API](../../../docs/subsystems/persistence.md#cordis-surface).
+
+### Design concept
+
+The package is the Service Definition of a capability seam with two halves. The abstract `SessionPersistence` service is the public contract; a `PersistenceCoordinator` provides backend-neutral orchestration for buffering, serialization, materialization, repair, adoption, and quiescent disposal. A backend implements the small durable primitives for stored reads, append, repair, and listing, so JSONL and SQLite share lifecycle correctness while keeping different storage primitives.
+
+### The invariants every backend honors
+
+- **Append-only; a crashed turn is closed, not truncated.** Flushed events are never rewritten; `load` preserves an interrupted final turn and durably appends synthetic closers.
+- **Contiguous `seq`.** A gap in the middle of the log rejects; `append`'s first `seq` must equal the stored next-seq.
+- **Lossless JSON data.** Batches pass the shared one-pass lossless-JSON boundary; non-serializable payloads reject at the append site.
+- **Durability.** `append` resolves only once the batch is durable.
+
+### Source map
+
+| File | Role |
 |---|---|
-| `locate(meta): SessionLocation \| undefined` | Resolve an absolute per-session artifact target without I/O or materialization. Backends without an independent local artifact return `undefined`. |
-| `supportsRawArtifacts: boolean` | State explicitly whether this backend exposes one verbatim artifact per session. Consumers check this capability before calling `readRaw`; `false` is not session absence. |
-| `readRaw(id, signal?): Promise<SessionRawArtifact \| undefined>` | Read a supported backend's own artifact text verbatim, decoded from its physical encoding but never reconstructed from events. `undefined` means only that the requested artifact is absent; an unsupported backend rejects. |
-| `create(meta): Promise<void>` | Register a new session's metadata. MAY defer the physical write until the first `append` (lazy materialization). |
-| `ensureMaterialized(session): Promise<void>` | Explicitly make an exact live session durable even with zero events, without inventing an event. Lifecycle frontends use this only when the empty session itself is a resumable resource; ordinary creation remains lazy. |
-| `append(id, events): Promise<void>` | Durably persist a batch. Append-only; first event `seq` == stored next-seq after any repair; rejects non-JSON-serializable data naming the offending type. |
-| `prepare(id, signal?): Promise<SessionPreparation>` | Reserve the exact unpublished Session used by resume. A coordinator reuses an earlier inspection when available, commits pending recovery, and releases an unpublished reservation back to its bounded cache on disposal. |
-| `load(id): Promise<{ meta; events }>` | Return an immutable balanced logical log after converting supported older records from the same format version and committing cold recovery. A live load first flushes its snapshot and rejects while its turn is open; a cold load preserves an interrupted final turn and durably closes it with synthetic `tool/result`/`step/end?`/`turn/end {interrupted}` events. Only a torn tail fragment is dropped; committed corruption and malformed records reject as `SessionPersistenceCorruptionError`, while an unsupported format `version` or an event type unknown to this build (without the envelope's `ignorable` marker) refuses as `SessionFormatUnsupportedError`, naming the refusal direction and the raw log path when the backend keeps one artifact per session. |
-| `inspect(id, signal?): Promise<{ meta; events }>` | Return an upgraded, validated, deeply frozen logical view without committing recovery or publishing a Session. A cold view receives in-memory synthetic recovery closers while its physical torn tail remains untouched; an already-live view is its current immutable snapshot and may contain an open turn. Coordinator-backed implementations retain the exact cold unpublished Session in a bounded LRU for later `prepare`, but discard and reload it when the stored revision changes. Same-id inspections share an in-flight read. |
-| `readFrom(id, fromSeq, signal?): Promise<{ meta; events }>` | Return valid stored events with `seq >= fromSeq` without preparation caching, truncation, closers, or coordinator state. A `fromSeq` at or past the stored end returns an empty event list; a negative or non-safe-integer `fromSeq` rejects. Seek-capable backends (SQLite) read only the suffix unless converting a supported older record requires earlier records; sequential backends (JSONL) parse the whole artifact and skip forward. Unknown-type refusal follows that access pattern: a seek read checks only the returned suffix, while the sequential fallback also refuses on an unknown required event below the window. Intended for checkpoint consumers that apply only events after a stored sequence number. |
-| `list(signal?): Promise<SessionHeader[]>` | Lightweight listing from metadata, no full-log parse. The optional signal cancels backend listing work. A zero-event session is absent until a consumer explicitly materializes it. |
-| `listSnapshots(signal?): Promise<SessionPersistenceSnapshot[]>` | Lightweight metadata plus an opaque branded per-log revision, without loading event logs. A revision stays equal while that log and its backing store are unchanged, changes after append or mutating load repair, and cannot collide solely because two stores use the same local counter. The optional signal requests cancellation of backend discovery work; first-party backends settle any started listing work before rejecting so an awaited call is quiescent. |
+| [`src/index.ts`](src/index.ts) | Plugin entry: the abstract `SessionPersistence` service and re-exported metadata types |
+| [`src/coordinator.ts`](src/coordinator.ts) | Shared write orchestration: batching, serialization, repair, adoption, disposal, format refusal |
+| [`src/write-behind.ts`](src/write-behind.ts) | The per-session bounded write controller and flush barrier |
+| [`src/preparations.ts`](src/preparations.ts) | Bounded retention of unpublished Session preparations for resume reuse |
+| [`src/revision.ts`](src/revision.ts) | The branded opaque revision token |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; the coordinator asserts stored/live identity and cwd) |
 
-## Invariants every backend must honor
+### The write path at a glance
 
-- **Append-only; a crashed turn is closed, not truncated.** Flushed events are never rewritten. A crash can leave an unclosed final turn whose events are real and possibly large; `load` preserves them and durably appends synthetic closers (a risk-classified error `tool/result` per unanswered assistant call, then `step/end?`+`turn/end {interrupted}`) to balance the log and keep the rehydrated history a valid provider transcript. Only a never-fully-written torn tail fragment is discarded.
-- **Contiguous seq.** `load` rejects a `seq` gap/parse error in the MIDDLE of the log; `append`'s first `seq` must equal the stored next-seq.
-- **JSON-serializable data.** `append` materializes each direct/replay batch through the shared one-pass lossless-JSON boundary. Live `Session` events are already deep-frozen, but the write coordinator still copies each event into a persistence-owned buffer.
-- **Durability.** `append` returns only once the batch is durable.
+Each `session/event` copies the event into its session's controller. The first pending event starts a fixed batching window; later events join without resetting its deadline. Expiry starts one durable append; events admitted during that write form a separately bounded follow-up batch. `session/flush` cancels the wait and drains through quiescence, so the loop uses it as the ordering and error-observation checkpoint before the next turn. A rejected background write retains its events and pauses automatic retry; a new event starts a fresh window, while explicit flush or backend teardown retries immediately.
 
-## The write coordinator
+### Stored-record compatibility
 
-`PersistenceCoordinator` owns per-id state and serialization, one bounded write controller per live session, lazy materialization, crash-tail repair, session adoption, and quiescent disposal. A first-party backend composes one, implements the small `PersistenceBackend` storage hook interface, and delegates its stateful methods. JSONL and SQLite therefore share lifecycle correctness while retaining different storage primitives; see the [coordinator Agent Note](../../../.agents/notes/implemented/architecture/2026-06-18-shared-persistence-write-coordinator.md), [flush-controller simplification](../../../.agents/notes/implemented/simplification/2026-07-23-collapse-persistence-flush-state.md), and [bounded batching decision](../../../.agents/notes/implemented/architecture/2026-08-08-bounded-session-persistence-write-batching.md).
+Backend reads normalize only the explicitly supported v0 record variants before validating current records. The coordinator uses the same normalized view for `load`, `inspect`, `readFrom`, ownerless-state claims, and HMR adoption. Reads do not rewrite stored records, and later appends use current v0. The [pre-identity message](../../../.agents/notes/implemented/bug-fix/2026-07-28-load-pre-identity-session-messages.md) and [pre-react-loop session](../../../.agents/notes/implemented/bug-fix/2026-08-04-load-pre-react-loop-sessions.md) notes own these bounded exceptions; they are not a general format-migration promise.
 
-Each `session/event` copies its event into the session controller. The first pending event starts a fixed batching window; later events join without resetting its deadline. The configured `writeBatchMaxDelayMs` bounds this intentional wait, not event-loop, initialization, serialized-operation, or backend latency. Events admitted during a write form a new bounded batch. `session/flush` cancels the wait and is a shared quiescence barrier that drains events admitted while it runs. A background failure is logged once, retains the ordered batch, and pauses automatic retry; a new event starts a fresh window, while explicit flush or backend teardown retries immediately and surfaces a repeated failure.
+</details>
+-----
 
-Crash repair is cold-only. For a live id, `load(id)` snapshots the authoritative in-memory log, waits for that snapshot to become durable, and returns it only when balanced; an open live turn rejects instead of receiving synthetic interruption closers. For a cold id, inspection reads, validates, freezes, and constructs one unpublished Session; repeated inspection reuses that object graph only while its source revision remains current. `prepare(id)` performs the same check before repair, reserves the exact Session, commits any pending torn-tail/interrupted-turn repair, and returns it for publication. HMR adoption reads through `loadStored`, applies the coordinator's cwd check, and never closes the active turn.
+<a id="further-exploration"></a>
+## Further Exploration
 
-Backend reads convert the exact supported older records from the same format version before validating current records. Pre-identity messages receive the deterministic id `legacy-message:<session-id>:<event-seq>`; a tool-result content replacement inherits its target's imported id. A pre-react-loop `turn/start` loses its obsolete trigger, a removed `steering/message` becomes the same identified `user/message`, and an older `turn/end` maps its terminal reason without inventing a caller that the old record did not name. The coordinator uses the same converted view for `load`, `inspect`, `readFrom`, ownerless-state claims, and HMR prefix adoption. Storage remains append-only: reads do not rewrite old records, and later appends use the current format. These are narrow import exceptions from the [pre-identity message](../../../.agents/notes/implemented/bug-fix/2026-07-28-load-pre-identity-session-messages.md) and [pre-react-loop session](../../../.agents/notes/implemented/bug-fix/2026-08-04-load-pre-react-loop-sessions.md) decisions, not a general v0 migration promise.
+Read these pages when the package-level contract is not enough. They move from the shared durability model to the shipped backends and the decision evidence.
 
-When a live session emits `session/disposed`, the coordinator waits for its controller, serializes a final drain, then releases state owned by that exact `Session` object. Failed retirement leaves the controller in the live-session map, so backend teardown can retry it. Backend teardown stops event admission first, flushes every remaining controller, awaits per-id operations, and only then closes the storage handle.

-The side-effect-free `locate`, lightweight `listSnapshots`, and per-id `readStoredRevision` queries remain backend-owned because they describe storage topology and revision identity rather than write orchestration. `listSnapshots(signal?)` passes the caller's exact signal into backend discovery so observers can cancel that work without detaching it.
-
-The `PersistenceBackend<TornMarker>` hooks (the only contract between the coordinator and storage):
-
-| Hook | Role |
-|---|---|
-| `name` | Backend label for the dispose-failure `AggregateError`. |
-| `loadStored(id, signal?)` | Read a stored prefix by id across every storage scope. Used by resume/load, non-mutating inspect, live adoption, and the create-collision probe. The optional signal belongs to observation-only reads. Returned metadata identifies `id`; `revision` identifies exactly the returned header and events; an opaque `tornMarker` is present iff a torn tail must be truncated. |
-| `readStoredRevision(id, signal?)` | Read the current source-qualified revision for one id without loading its event log. It uses the same revision representation as `loadStored` and returns `undefined` when the id is absent. |
-| `loadStoredFrom?(id, fromSeq, signal?)` | Optional seek-capable suffix read behind the service's `readFrom`: the header plus stored events with `seq >= fromSeq`, non-mutating, no torn marker. SQLite implements it (`WHERE seq >= ?`); a backend that omits it gets the coordinator's fallback — `loadStored` plus a forward skip. |
-| `appendBatch(meta, events, isMaterialized)` | Durably append a contiguous batch, lazily materializing ATOMICALLY when not yet materialized. |
-| `materializeHeader?(meta)` | Durably create a header-only artifact for `ensureMaterialized`; required by providers that support durable empty sessions. |
-| `commitRepair(meta, tornMarker, closers)` | Make a crash repair durable: truncate the torn tail (iff `tornMarker !== undefined` — a marker may be falsy, e.g. seq/offset `0`) and append `closers`. NOT required to be atomic. Used by load (truncate + closers) and live-adoption (truncate only). |
-| `list(signal?)` | List all stored metadata, observing optional cancellation. |
-| `close?()` | Optional lifecycle teardown (e.g. close a db handle), awaited after the dispose drain. |
-
-The coordinator asserts the stored id and compares stored/live cwd before repair or live adoption. Its `inspect()` path takes ownership of fresh backend values, validates and freezes them once, and retains at most the configured number of unpublished Sessions without calling `commitRepair`. A retained source is reused or repaired only when its revision still equals `readStoredRevision`; otherwise the coordinator reloads it. This freshness check does not add cross-process writer exclusion. Revision retries converge when the durable log remains unchanged for one read/check round trip; continuous external writers can delay `load`, `inspect`, or `prepare`. The `tornMarker` is fully OPAQUE: the coordinator only tests `!== undefined` and round-trips it to `commitRepair`, never inspecting its value (the JSONL backend uses the byte offset to truncate to, the SQLite backend the seq to delete from). A third-party backend MAY implement the abstract service directly without the coordinator, but it must provide the same non-mutating inspection and trustworthy lightweight snapshot revisions. See [the write-coordinator Agent Note](../../../.agents/notes/implemented/architecture/2026-06-18-shared-persistence-write-coordinator.md).

-## Metadata and location types
-
-Re-exported from `dsh-session`: `SessionHeader` (immutable session metadata: `version`, `id`, `createdAt`, `cwd?`, `parentSession?`, `seedLength?`, `origin?`, `delegationDepth?`). `SessionLocation` is `{ readonly kind: string; readonly path: string }`; its path is an absolute backend target, not proof that the artifact exists or contains an unflushed turn.

-This seam adds no prompt or schema. Resume restores stored surface events as message history; stored request headers reconstruct earlier calls, while the new loop composes the current system prompt, tools, and session prefix for its next request. Crash repair marks an assistant request without a durable call as `TOOL_NOT_STARTED`; a durable call without a result becomes `TOOL_OUTCOME_UNKNOWN`, whose text lets the model retry read-only or idempotent work but directs it to verify side effects or ask the user instead of retrying blindly.

-会话持久化是一项能力 seam。抽象的 `SessionPersistence` 服务（`ctx.sessionPersistence`）是其 Service Definition。它要求持久化后端持久存储、重新加载和列出会话，但不规定具体存储实现。该 seam 采用与 `dsh-shell` 相同的角色划分（见[能力 seam](../../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.zh.md)）：本包负责 Service Definition，同级包负责 Service Provider，Consumer 注入该服务。
+## 概述
 
-持久化单元就是现有 `SessionEvent`（事件溯源模型：日志是唯一真源），因此不存在另一套并行的「持久消息」类型。不属于可回放对话状态的元数据（格式版本、cwd、血缘、种子边界、origin、委托深度）作为 `SessionHeader` 单独传输，该类型归 `dsh-session` 所有，并在此重新导出。
+`dsh-session-persistence` 通过每个持久化后端都实现的一个后端无关服务（`ctx.sessionPersistence`）持久存储会话的事件日志、在恢复时重新加载并列出已存储会话。持久化单元就是现有 `SessionEvent` 日志——不存在另一套并行的存储消息类型——不可回放的元数据（格式版本、工作目录、血缘、种子边界）作为 `SessionHeader` 单独传输。后端拥有自己的存储，服务拥有语义：仅追加日志、连续序列号、保留中断轮次而非截断的崩溃恢复，以及只在批次安全后才返回的持久写入。选一个后端（按会话存储文件的 `session-persistence-jsonl`，或单库的 `session-persistence-sqlite`），挂载它，会话就会持久化并在恢复时还原，loop 与模型无需知道下面是哪个后端。

+<a id="use-this-package"></a>
+## 使用本包
+
+挂载一个持久化后端即可让会话持久化。后端把自己注册为 `ctx.sessionPersistence`；组合中的其他部分不变——loop、恢复与回放调用的是同一个服务。
+
+### 选择后端
+
+seam 随产品交付两个可互换后端。当每个会话应各占一份磁盘产物时选择 [JSONL](../session-persistence-jsonl/README.zh.md)：它把每个会话存为一份仅追加 `.jsonl.zstd` 日志，并由 `locate(meta)` 返回绝对产物路径。当单一可查询数据库适合部署时选择 [SQLite](../session-persistence-sqlite/README.zh.md)：它把每个会话的日志连同物理打包行一起存入单个数据库，不返回按会话的产物。第三方后端可以直接实现该服务；必须遵守的[后端约定](#understand-the-implementation)见下文。
+
+### 服务提供什么
+
+挂载后端后，你可以持久存储会话事件、重新加载已存储日志并列出已存储内容：
+
+```text
+await ctx.sessionPersistence.create(meta)                  // register a session
+await ctx.sessionPersistence.ensureMaterialized(session)   // persist an empty resumable session
+await ctx.sessionPersistence.append(id, events)            // durably persist a batch
+const { meta, events } = await ctx.sessionPersistence.load(id)   // reload on resume
+const headers = await ctx.sessionPersistence.list()        // every stored session
+```
+
+`append` 只在批次持久后返回，因此成功返回的写入在操作系统崩溃或断电后依然存在。普通 `create` 保持惰性；只有当空会话本身必须出现在持久列表中时，生命周期前端才调用 `ensureMaterialized`，且不会虚构事件。`load` 返回不可变的平衡日志并提交任何需要的崩溃恢复；`inspect` 读取同一视图但不提交恢复。从水位恢复的消费方可以只读取该序列号及之后的已存储事件，会话的产物位置（`locate`）不经文件系统 I/O 即可解析。
+
+### 恢复与崩溃恢复
+
+恢复就是 `load` 加会话准备：存储日志连同其头部血缘一起返回，因此恢复后的 agent（智能体）看到相同的历史与组装。中途崩溃的会话重新加载时，其被中断的最终轮次会保留并保持平衡：`load` 为未获回答的调用追加合成 `tool/result` 与 `turn/end {interrupted}` closer，而不是丢弃事件——单个轮次可能很大，而这些事件在崩溃前已持久写入。只有从未完整写入的撕裂尾部碎片会被丢弃。
+
+### 失败与恢复
+
+当前构建无法忠实解读的存储日志会以方向感知的错误被拒绝，绝不错读。`SESSION_FORMAT_VERSION` 保持 v0，本构建不提供格式迁移路径；更高版本会要求操作者升级 harness。解码器只接受下文点名的有限同版本记录变体。本构建不认识的事件类型会被拒绝，除非其信封标记为 `ignorable`；已提交前缀中的损坏以 `SessionPersistenceCorruptionError` 拒绝。对仍绑定到活动会话的 id 执行 `load`，会先刷新其快照并在轮次开放时拒绝；冷 load 应用恢复。

+## 理解实现
+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节说明 seam 如何实现持久存储以及后端如何接入；可观察约定见[使用本包](#use-this-package)与生成的 [Cordis API](../../../docs/subsystems/persistence.zh.md#cordis-surface)。
+
+### 设计理念
+
+本包是能力 seam 的 Service Definition，分两半。抽象的 `SessionPersistence` 服务是公开约定；`PersistenceCoordinator` 为缓冲、串行化、物化、修复、接管与完全停稳的 dispose 提供后端无关编排。后端实现存储读取、追加、修复与列出所需的小型持久原语，因此 JSONL 与 SQLite 共享生命周期正确性，同时保留不同的存储原语。
+
+### 每个后端必须遵守的不变量
+
+- **仅追加；崩溃轮次会被关闭，而非截断。** 已 flush 事件绝不重写；`load` 保留中断的最终轮次并持久追加合成 closer。
+- **连续 `seq`。** 日志中间的缺口会被拒绝；`append` 的第一个 `seq` 必须等于已存储 next-seq。
+- **无损 JSON 数据。** 批次经过共享单遍无损 JSON 边界；无法序列化的载荷在 append 处被拒绝。
+- **持久性。** `append` 只在批次持久后返回。

+
+| 文件 | 职责 |
 |---|---|
-| `locate(meta): SessionLocation \| undefined` | 在不执行 I/O 或实体化的情况下解析每个会话的绝对产物目标。没有独立本地产物的后端返回 `undefined`。 |
-| `supportsRawArtifacts: boolean` | 明确说明该后端是否为每个会话暴露一份逐字工件。Consumer 在调用 `readRaw` 前检查此能力；`false` 并不表示会话缺失。 |
-| `readRaw(id, signal?): Promise<SessionRawArtifact \| undefined>` | 读取受支持后端自身的逐字工件文本；只解码物理编码，绝不从事件重建。`undefined` 仅表示所请求工件缺失；不支持的后端会拒绝。 |
-| `create(meta): Promise<void>` | 注册新会话元数据。可以将物理写入延迟到第一次 `append`（延迟实体化）。 |
-| `ensureMaterialized(session): Promise<void>` | 在不虚构事件的情况下，显式使一个确切 live session 即使零事件也保持持久。只有当空会话本身是可恢复资源时，生命周期前端才使用它；普通创建仍保持延迟实体化。 |
-| `append(id, events): Promise<void>` | 持久保存一个批次。仅追加；任何修复后，第一个事件 `seq` == 已存储 next-seq；非 JSON 可序列化数据会被拒绝，并命名违规类型。 |
-| `prepare(id, signal?): Promise<SessionPreparation>` | 预留恢复所使用的那个未发布 Session。协调器会尽可能复用之前的检查结果、提交待处理恢复，并在 dispose（资源释放）时将未发布 reservation 释放回有界缓存。 |
-| `load(id): Promise<{ meta; events }>` | 转换同一格式版本中受支持的旧记录后，返回不可变、平衡的逻辑日志，并提交冷恢复。实时 load 先 flush 其快照，并在轮次开放时拒绝；冷 load 保留中断的最终轮次，并用合成 `tool/result`/`step/end?`/`turn/end {interrupted}` 事件持久关闭它。只丢弃撕裂尾部碎片；已提交损坏和格式错误的记录以 `SessionPersistenceCorruptionError` 拒绝，不支持的格式 `version` 或本构建不认识且信封未带 `ignorable` 标记的事件类型以 `SessionFormatUnsupportedError` 拒绝，消息说明拒绝方向，并在后端为每个会话保留独立文件时给出原始日志路径。 |
-| `inspect(id, signal?): Promise<{ meta; events }>` | 返回已经升级、验证和深度冻结的逻辑视图，但不提交恢复或发布 Session。冷视图会获得仅存在于内存的合成恢复 closer，物理撕裂尾部保持不变；实时状态下的视图则是当前不可变快照，可能包含开放的轮次。基于协调器的实现会在有界 LRU 中保留该冷状态下未发布的 Session 本身，供后续 `prepare` 使用，但已存储修订值变化后会丢弃并重新读取。同 id 检查共享进行中的读取。 |
-| `readFrom(id, fromSeq, signal?): Promise<{ meta; events }>` | 返回 `seq >= fromSeq` 的有效已存储事件，不进入 preparation 缓存、不截断、不合成 closer，也不发布协调器状态。`fromSeq` 达到或超过已存储末尾时返回空事件列表；负数或非安全整数 `fromSeq` 会被拒绝。可寻址后端（SQLite）只读后缀，除非转换受支持的旧记录需要读取更早的记录；顺序后端（JSONL）解析整个产物并向前跳过。未知类型拒绝遵循同一读取方式：寻址读取只检查返回的后缀，顺序回退路径还会拒绝窗口以下的未知必需事件。供 checkpoint 消费方只应用已存序号之后的事件。 |
-| `list(signal?): Promise<SessionHeader[]>` | 从元数据轻量列出，不解析完整日志。可选信号取消后端列表工作。零事件会话在 consumer 显式实体化前不在 `list` 中。 |
-| `listSnapshots(signal?): Promise<SessionPersistenceSnapshot[]>` | 返回轻量元数据和每份日志一个不透明、带品牌类型的修订值，不加载事件日志。日志及其后端存储不变时，修订保持相等；append 或变更性 load 修复后会改变；不会仅因两个存储使用相同本地计数器而冲突。可选信号请求取消后端发现工作；第一方后端会先等待所有已启动的列出工作结束，再予以拒绝，因此调用返回拒绝时，相关工作已完全停稳。 |

-## 每个后端必须遵守的不变量
+### 写入路径概览
 
-- **仅追加；崩溃轮次会被关闭，而非截断。** 已 flush 事件绝不重写。崩溃可留下未关闭最终轮次，其事件真实且可能很大；`load` 保留它们，并持久追加合成 closer（为每个未获回答的 assistant 调用添加一个带风险分类错误的 `tool/result`，再添加 `step/end?`+`turn/end {interrupted}`），以平衡日志，并确保重新载入的历史仍是有效的提供方 transcript（文本记录）。只丢弃从未完整写入的撕裂尾部碎片。
-- **连续 seq。**`load` 拒绝日志中间的 `seq` 缺口/解析错误；`append` 的第一个 `seq` 必须等于已存储 next-seq。
-- **JSON 可序列化数据。**`append` 通过共享单遍无损 JSON 边界实体化每个直接/回放批次。活动 `Session` 事件已深度冻结，但写入协调器仍将每个事件复制到持久化自有缓冲区。
-- **持久性。**`append` 只在批次持久后返回。
+每个 `session/event` 把事件复制到其会话的 controller。第一个待处理事件开启固定批处理窗口；后续事件加入但不重置截止时间。窗口到期后启动一次持久追加；该次写入期间接纳的事件形成另一个独立有界的后续批次。`session/flush` 取消等待并排空至完全停稳，因此 loop 在下一轮次前把它用作排序与错误观察检查点。被拒绝的后台写入保留其事件并暂停自动重试；新事件开启新窗口，而显式 flush 或后端拆卸会立即重试。
 
-## 写入协调器
+### 存储记录兼容
 
-`PersistenceCoordinator` 负责每 id 状态和串行化、每个活动会话各自的有界写入 controller、延迟实体化、崩溃尾部修复、会话接管和完全停稳的 dispose。第一方后端组合一个协调器，实现小型 `PersistenceBackend` 存储钩子接口，并委托其有状态方法。因此 JSONL 和 SQLite 共享生命周期正确性，同时保留不同存储原语；见[协调器 Agent Note](../../../.agents/notes/implemented/architecture/2026-06-18-shared-persistence-write-coordinator.zh.md)、[flush controller 简化](../../../.agents/notes/implemented/simplification/2026-07-23-collapse-persistence-flush-state.zh.md)和[有界批处理决策](../../../.agents/notes/implemented/architecture/2026-08-08-bounded-session-persistence-write-batching.zh.md)。
+后端读取只会在校验当前记录之前，规范化明确支持的 v0 记录变体。协调器对 `load`、`inspect`、`readFrom`、无所有者状态认领与 HMR 接管使用同一份规范化视图。读取不会重写已存记录，后续追加使用当前 v0。[消息标识机制引入前的消息](../../../.agents/notes/implemented/bug-fix/2026-07-28-load-pre-identity-session-messages.zh.md)与 [react-loop 引入前会话](../../../.agents/notes/implemented/bug-fix/2026-08-04-load-pre-react-loop-sessions.zh.md)笔记规定这些有限例外；它们不构成通用格式迁移承诺。
 
-每个 `session/event` 将事件复制到会话 controller。第一个待处理事件会开启固定批处理窗口；后续事件会加入该批次，但不会重置截止时间。配置的 `writeBatchMaxDelayMs` 只限制这段有意等待，而不限制事件循环、初始化、串行化操作或后端延迟。写入期间接纳的事件会形成一个新的有界批次。`session/flush` 会取消等待，并作为共享的完全停稳屏障，排空屏障运行期间接纳的事件。后台写入失败只记录一次日志，保留顺序不变的批次，并暂停自动重试；新事件会开启新的固定窗口，而显式 flush 或后端拆卸会立即重试，并在失败再次发生时向调用方暴露失败。
+</details>
+-----
 
-崩溃修复只适用于冷状态。对于已有活动会话的 id，`load(id)` 为权威内存日志制作快照，等待该快照持久，并只在平衡时返回；活动会话中开放的轮次会被拒绝，而不会收到合成中断 closer。对于冷 id，检查只读取、验证、冻结并构造一次未发布 Session；只有来源修订值仍然是当前值时，重复检查才会复用该对象图。`prepare(id)` 在修复前执行相同校验，预留该 Session 本身，提交任何待处理的撕裂尾部或中断轮次修复，并将其返回用于发布。HMR（热模块替换）接管通过 `loadStored` 读取，应用协调器 cwd 检查，并绝不关闭活动轮次。
+<a id="further-exploration"></a>
+## 进一步探索
 
-后端读取会在验证当前记录前，转换同一格式版本中明确受支持的旧记录。消息标识机制引入前的消息会获得确定性的 id `legacy-message:<session-id>:<event-seq>`；工具结果的内容替换会继承其目标导入后的 id。react-loop 引入前的 `turn/start` 会移除过时的 trigger，已移除的 steering（中途引导）事件 `steering/message` 会转换为同一条带标识的 `user/message`；旧版 `turn/end` 会映射终止原因，但不会虚构旧记录中没有记载的调用方。协调器对 `load`、`inspect`、`readFrom`、无所有者状态的认领和 HMR 前缀接管使用同一份转换后视图。存储仍然仅追加：读取不会重写旧记录，此后追加的事件使用当前格式。这些是[消息标识机制引入前的消息](../../../.agents/notes/implemented/bug-fix/2026-07-28-load-pre-identity-session-messages.zh.md)与 [react-loop 引入前会话](../../../.agents/notes/implemented/bug-fix/2026-08-04-load-pre-react-loop-sessions.zh.md)决策所规定的范围受限的导入例外，并不构成通用的 v0 迁移承诺。
+当包级约定不够用时阅读以下页面。它们从共享持久性模型逐步进入随产品交付的后端与决策证据。
 
-活动会话发出 `session/disposed` 时，协调器等待其 controller，以串行方式执行最终 drain，然后释放该精确 `Session` 对象拥有的状态。失败退役会将 controller 保留在活动会话 map 中，使后端拆卸可重试。后端拆卸先停止事件接纳，flush 每个剩余 controller，等待每 id 操作，最后才关闭存储句柄。

-无副作用 `locate`、轻量 `listSnapshots` 和按 id 查询的 `readStoredRevision` 仍由后端负责，因为它们描述存储拓扑和修订身份，而非写入编排。`listSnapshots(signal?)` 将调用方传入的同一个信号传给后端发现流程，使观察者可在不脱离该工作的情况下取消。

-`PersistenceBackend<TornMarker>` 钩子（协调器与存储之间的唯一约定）：

-| 钩子 | 职责 |
-|---|---|
-| `name` | dispose 失败 `AggregateError` 的后端标签。 |
-| `loadStored(id, signal?)` | 在全部存储范围中按 id 读取已存储前缀。用于恢复／加载、非修改式 inspect、活动会话接管和 create 冲突探测。可选信号属于仅观察读取。返回元数据标识 `id`；`revision` 精确标识返回的 header 和事件；当且仅当必须截断撕裂尾部时才存在不透明 `tornMarker`。 |
-| `readStoredRevision(id, signal?)` | 在不加载事件日志的情况下读取一个 id 当前的来源限定修订值。它使用与 `loadStored` 相同的修订值表示；id 不存在时返回 `undefined`。 |
-| `loadStoredFrom?(id, fromSeq, signal?)` | 服务 `readFrom` 背后的可选可寻址后缀读取：返回 header 和 `seq >= fromSeq` 的已存储事件，非修改式、无撕裂标记。SQLite 实现它（`WHERE seq >= ?`）；不实现的后端使用协调器回退——`loadStored` 加向前跳过。 |
-| `appendBatch(meta, events, isMaterialized)` | 持久追加连续批次；尚未实体化时以原子方式延迟实体化。 |
-| `materializeHeader?(meta)` | 为 `ensureMaterialized` 持久创建仅含 header 的 artifact；支持持久空会话的 provider 必须实现。 |
-| `commitRepair(meta, tornMarker, closers)` | 使崩溃修复持久：截断撕裂尾部（当且仅当 `tornMarker !== undefined`；标记可为 falsy，例如 seq/offset `0`），并追加 `closers`。不要求原子性。由 load（截断 + closer）和活动会话接管（仅截断）使用。 |
-| `list(signal?)` | 列出全部已存储元数据，并遵循可选的取消信号。 |
-| `close?()` | 可选生命周期拆卸（例如关闭 db 句柄），在 dispose drain 后等待其完成。 |
-
-协调器断言已存储 id，并在修复或活动会话接管前比较已存储/活动会话 cwd。其 `inspect()` 路径取得新鲜后端值的所有权，只验证和冻结一次，并在不调用 `commitRepair` 的情况下最多保留配置数量的未发布 Session。只有保留源的修订值仍等于 `readStoredRevision` 时，系统才会复用或修复它；否则协调器会重新读取。该新鲜性校验不会增加跨进程写入排他。持久日志在一次读取与复核往返内保持不变时，修订值重试才能收敛；持续的外部写入可能延迟 `load`、`inspect` 或 `prepare`。`tornMarker` 完全不透明：协调器只测试 `!== undefined`，并将其原样往返给 `commitRepair`，绝不检查值（JSONL 后端使用待截断字节偏移，SQLite 后端使用待删除 seq）。第三方后端可以不用协调器直接实现抽象服务，但必须提供相同的非修改式检查和可信轻量快照修订。详见[写入协调器 Agent Note](../../../.agents/notes/implemented/architecture/2026-06-18-shared-persistence-write-coordinator.zh.md)。

-The persisted projection cache (`ctx.sessionProjectionCache`): durable checkpoints of every projection unit's state, one version-stamped document per session on the `session_projcache` storage domain in `per-record` layout (the shipped json backend lands each session's record at `<root>/session_projcache/sessions/<id>.json`). The cache never consults the persistence layer. Design authority: the [session-projection RFC](../../../.agents/notes/proposed/architecture/2026-07-27-session-projection-and-command-log.md) (persisted projection cache section).
+## Summary
 
-A stored row `(key → {ver, seq, val})` is a fold shortcut, never an authority: possibly stale (`seq` says exactly how stale) but never wrong. Consequences the implementation commits to:
+`dsh-session-projection-cache` persists the state checkpoints of every registered projection unit (`ctx.sessionProjectionCache`) as one versioned document per session in the `session_projcache` storage domain's `per-record` layout. The shipped JSON backend stores each record at `<root>/session_projcache/sessions/<id>.json`, and the cache never reads the session-persistence layer. A stored row is a fold shortcut, never an authority: it may be stale — its `seq` says exactly how stale — but never wrong. Three mandatory checkpoints (session creation, `turn/end`, and session disposal) plus configurable count and interval throttles keep the cache fresh. Choose it when list views need synchronous cached values or cold projection folds should skip an already-checkpointed prefix.
 
-- **Reads and writes share one coherent state.** Every read is a synchronous lookup in the domain's in-memory tables; every write queues on the domain's per-unit write chain and mutates memory only after durability, so a read can never go around the write chain to the medium (no direct disk reads, no torn values).
-- **Every background write is fail-soft.** A failed durable write logs a warning and keeps the cache stale; the next write self-heals. A crash between writes costs a longer tail replay, never a wrong value.
-- **A `ver` mismatch against the live unit's `stateVersion` discards, never migrates.** A unit bump invalidates its rows at read time; the key refolds from the log.
-- **A row must pass the live unit's `stateSchema`.** A malformed or stale record document reads as "no cache row" at open, so the cold path refolds from the log.
-- **Whole-record writes.** Each write atomically replaces the session's record document (the registry cut is always complete), snapshotted through the lossless-JSON boundary — a unit state violating the plain-JSON contract fails loud. The domain write chain serializes writes, so a newer cut never lands before an older one.
-- **Records are bound to a log lifecycle, not just an id.** Each record stores the header identity (`createdAt`, `cwd`) it was folded from; every read validates it (the live header is the witness) before accepting a record, so a deleted-then-recreated id cannot let an old record seed state folded from an unrelated log.
-- **The log leads, the cache follows.** A live checkpoint flushes the session's buffered events durably BEFORE the cache row lands, so a crash can leave the cache behind the log (a longer tail replay) but never ahead of it.
-- **The medium is the domain's, private by default.** The json backend creates its tree owner-only (`0o700`); the cache does not depend on which persistence backend is mounted — no `locate`, no per-session-dir probing.

-| Session creation | Mandatory — the seed-derived cut (a forked child's inherited title, say) lands immediately, so a crash or a live-held session never loses it from the cold list. |
-| `turn/end` | Mandatory — the turn-final value is what listing reads want. |
-| Session disposal (detach) | Mandatory — the live-to-cold moment; after it the cache serves this session's final cut. |
-| `writeEveryEvents` committed events | Config throttle (count). |
-| `writeIntervalMs` since the first dirty event | Config throttle (interval). |

+## Use this package
 
-Both throttle triggers are required `Config` fields (no defaults): the flush cadence is a deployment choice stated in cordis.yml.
+Mount this package beside the projection registry and the storage stack when clients should list projection values for cold sessions without loading their logs. Without it, consumers must obtain the log before they can reconstruct cold projection values.
 
-## Listing read (`cachedSnapshot(meta)`)
+### When to choose it
 
-A synchronous, zero-I/O read from the domain's in-memory tables: client values viewed straight from the identity-matching stored record (version- and state-schema-matching keys only), returned as a `{asOfSeq, values}` cut — `asOfSeq` is the lowest served-row watermark, so a client seeding its per-session value store under higher-seq-wins can never let a stale list block overwrite a newer push frame. Host-only rows are never returned. `undefined` when no usable client row exists (unknown id, unrelated lifecycle, absent or foreign record document, or no usable rows); the api-proxy list carrier turns that into an absent column.
+Choose it when a deployment restarts sessions and needs durable projection values for history lists, statistics, or goal snapshots. Skip it when projections serve only live sessions, or when the extra storage writes cost more than the saved projection work.
 
-`write(session)` is the synchronous-cut checkpoint both mandatory points use; carriers may call it directly (not fail-soft — the fail-soft wrappers own containment).

+
+### How checkpoints are written
+
+Three mandatory points always write: session creation persists the seed-derived cut, `turn/end` persists the value that listing reads want, and session disposal persists the final live cut. Between them, the configured count and interval throttles write as events accumulate. Every write atomically replaces the session's complete record through the domain write chain; a failure logs a warning and keeps the cache stale, and the next write self-heals.
+
+### Reading cached values
+
+`cachedSnapshot(meta)` synchronously serves client values from the storage domain's in-memory tables with zero I/O. It accepts only an identity-matching record and version- and schema-matching keys, then returns a `{ asOfSeq, values }` cut at the lowest served-row watermark. It returns `undefined` for an unknown id, unrelated lifecycle, absent or foreign record document, or no usable rows. `coldSnapshot(meta, events)` accepts a complete ordered log, skips the checkpointed prefix while folding, and refreshes the record without reading the persistence layer itself.
+
+### What the cache guarantees
+
+The log leads and the cache follows: a live checkpoint flushes the session's buffered events durably before the cache row lands, so a crash can leave the cache behind the log but never ahead of it. Reads and writes share the storage domain's coherent in-memory state; the per-unit write chain mutates memory only after durability. Each version-stamped record must match the live unit schema and session header identity (`createdAt`, `cwd`), so malformed, stale, or unrelated records read as absent. The JSON backend stores each record at `<root>/session_projcache/sessions/<id>.json` in an owner-only directory tree.

+
+### Design concept
+
+The cache is a fold shortcut over the projection registry's checkpoint face, stored in a `per-record` domain data table. It commits to six consequences: reads never bypass the domain write chain; every background write is fail-soft; a `ver` mismatch discards rather than migrates a row; a record must pass the live unit's `stateSchema`; writes replace one complete session record through the lossless-JSON boundary; and the log leads, the cache follows.
+
+### Read and write ownership
+
+The cache stores one version-stamped document per session in the `session_projcache` domain. It does not depend on a session-persistence backend, call `locate`, or inspect per-session directories. A malformed or stale record reads as absent, and consumers that require a cold value own any log refold.

-持久投影缓存（`ctx.sessionProjectionCache`）：把每个投影单元的状态保存为检查点，在 `per-record` 布局的 `session_projcache` 存储域上为每个会话存一份带版本戳的文档（内置 json 后端把每个会话的记录落在 `<root>/session_projcache/sessions/<id>.json`）。缓存绝不咨询持久化层。设计权威：[session-projection RFC](../../../.agents/notes/proposed/architecture/2026-07-27-session-projection-and-command-log.zh.md)（persisted projection cache 一节）。
+## 概述
 
-一条存储行 `(key → {ver, seq, val})` 是折叠捷径，绝不是权威：可能陈旧（`seq` 精确说明陈旧到哪），但绝不会错。实现据此承诺：
+`dsh-session-projection-cache` 将每个已注册投影单元的状态检查点（`ctx.sessionProjectionCache`）存为 `session_projcache` 存储域 `per-record` 布局下的逐会话版本化文档。随附 JSON 后端将每条记录存于 `<root>/session_projcache/sessions/<id>.json`，缓存绝不读取会话持久化层。存储行是折叠捷径，绝不是权威：它可能陈旧——`seq` 精确说明陈旧到哪——但绝不会错。三个必写点（会话创建、`turn/end` 与会话释放）加上可配置的条数与间隔节流让缓存保持新鲜。当列表视图需要同步缓存值，或冷投影折叠应跳过已检查点化的前缀时，选择本包。
 
-- **读写共享同一份一致状态。** 每次读取都是对域内存表的同步查找；每次写入排进该域的单条写链，先落盘成功才改内存——读永远不会绕过写链去碰介质（没有直读磁盘、没有撕裂的值）。
-- **每次后台写入都 fail-soft。** 持久写失败只记一条警告并保持缓存陈旧；下一次写入自愈。两次写之间崩溃的代价是更长的尾部回放，绝不是错误的值。
-- **`ver` 与当前运行单元的 `stateVersion` 不匹配即丢弃，绝不迁移。** 单元递增版本会在读取时使其行失效；该 key 从日志重新折叠。
-- **存储行必须通过当前单元的 `stateSchema`。** 畸形或过期的记录文档在打开时读作"无缓存行"，冷路径从日志重新折叠。
-- **整记录写入。** 每次写入原子替换该会话的记录文档（注册表切面始终是完整的），并经无损 JSON 边界快照——违反纯 JSON 约定的单元状态会显式失败并报错。域写链将写入串行化，新切面绝不会先于旧切面落盘。
-- **记录绑定到日志生命周期，而不只是 id。** 每条记录存储其折叠来源的 header 身份（`createdAt`、`cwd`）；每次读取先以活 header 为证验证它，再接受任何记录——被删后重建的 id 无法让旧记录播种来自无关日志的状态。
-- **日志领先，缓存跟随。** 活会话检查点先把缓冲事件持久 flush，缓存行才落地，因此崩溃只会让缓存落后于日志（更长的尾部回放），绝不领先于它。
-- **介质归域所有，默认私有。** json 后端以仅属主权限（`0o700`）创建自己的目录树；缓存不依赖挂载的是哪个持久化后端——没有 `locate`、没有每会话目录探测。

-| 累计 `writeEveryEvents` 个已提交事件 | 配置节流（条数）。 |
-| 距首个脏事件 `writeIntervalMs` 毫秒 | 配置节流（间隔）。 |

+当客户端应在不加载日志的情况下列出冷会话投影值时，把本包与投影注册表及存储栈一起挂载。没有它时，消费方必须先取得日志，才能重建冷投影值。
 
-## 列表读（`cachedSnapshot(meta)`）
+### 何时选择
 
-对域内存表的同步、零 I/O 读取：从身份匹配的存储记录直接 view 客户端值（仅版本与 state schema 均匹配的 key），以 `{asOfSeq, values}` 切面返回——`asOfSeq` 取所服务行的最低水位，客户端在 higher-seq-wins 规则下播种值存储时，陈旧列表块永远压不过更新的推送帧。host-only 行永不返回。无可用客户端行（未知 id、无关生命周期、记录文档缺失或外来、无可用行）时返回 `undefined`；api-proxy 列表载体将其转为列缺席。
+当部署会重启会话，并需要为历史列表、统计信息或 goal 快照提供持久投影值时，选择本包。当投影只服务实时会话，或额外存储写入的成本高于所节省的投影工作时，跳过本包。

+### 检查点如何写入
+
+三个必写点总是写入：会话创建保存由种子派生的切面，`turn/end` 保存列表读取所需的轮次终值，会话释放保存最终实时切面。其间，配置的条数与间隔节流随事件累积写入。每次写入通过领域写入链以原子方式替换该会话的完整记录；失败会记录警告并让缓存保持陈旧，后续写入会自行修复。
+
+### 读取缓存值
+
+`cachedSnapshot(meta)` 以零 I/O 从存储域的内存表同步提供客户端值。它只接受身份匹配的记录以及版本和 schema 均匹配的 key，再按所服务行的最低水位返回 `{ asOfSeq, values }` 切面。对于未知 id、无关生命周期、缺失或外来的记录文档，或没有可用行的情况，它返回 `undefined`。`coldSnapshot(meta, events)` 接受完整有序日志，在折叠时跳过已检查点化的前缀，并在自身不读取持久化层的情况下刷新记录。
+
+### 缓存保证什么
+
+日志领先，缓存跟随：实时检查点先把会话的缓冲事件持久化，然后才保存缓存记录。因此崩溃可能让缓存落后于日志，但绝不会让缓存领先。读取和写入共享存储域内一致的内存状态；逐单元写入链只在持久化成功后修改内存。每个带版本戳的记录必须匹配实时单元 schema 与会话 header 身份（`createdAt`、`cwd`），因此畸形、陈旧或无关的记录都会读作不存在。JSON 后端把每条记录存于仅所有者可访问的 `<root>/session_projcache/sessions/<id>.json` 目录树中。

+本节说明缓存的持久性与存储所有权；可观察行为已在[使用本包](#use-this-package)中说明。
+
+### 设计理念
+
+缓存是投影注册表检查点接口上的折叠捷径，存于 `per-record` 领域数据表中。它带来六项后果：读取绝不绕过领域写入链；每次后台写入都 fail-soft；`ver` 不匹配时丢弃而不迁移记录；记录必须通过实时单元的 `stateSchema`；写入通过无损 JSON 边界替换一份完整会话记录；日志领先，缓存跟随。
+
+### 读写所有权
+
+缓存在 `session_projcache` 领域中为每个会话保存一份带版本戳的文档。它不依赖会话持久化后端，不调用 `locate`，也不检查逐会话目录。畸形或陈旧的记录读作不存在；需要冷值的消费方负责提供日志以重新折叠。

-无，因为缓存只持久化 host 侧的、由已写入日志的会话状态派生的读模型，不触碰任何提示词、消息、schema、流或工具结果。
+无，因为持久缓存只加速主机侧的投影状态读取，不注册任何模型可见内容。

-Session-projection Service Definition and drive registry. It owns `ctx.sessionProjections`, the registry that drives every registered projection unit over committed session events and serves finished whole values to carriers, currently the api-proxy history tail page and `session/projection` push frame. A domain registers pure mathematics; the framework owns the drive. The [session-projection RFC](../../../.agents/notes/proposed/architecture/2026-07-27-session-projection-and-command-log.md) records the design rationale.
+## Summary
 
-## Service: `SessionProjectionRegistry` (ctx key: `sessionProjections`)
+`dsh-session-projection` serves whole current values of log-derived per-session state to client carriers — the history tail page and the `session/projection` push frame — through a registry (`ctx.sessionProjections`) that folds every committed session event through registered projection units. A domain registers a pure computation unit (initial state, a fold over events, and an optional client view); the framework owns the subscription, the drive, and change notification, so domains hold no subscriptions and clients receive finished values, never fold events themselves. Every served value is plain JSON validated against a schema, and a per-unit `stateVersion` anchors persisted-cache invalidation. Choose it when a client needs derived per-session state — a todo list, a goal snapshot, conversation stats — without folding the raw log itself.
 
-### Public API
+## Table of Contents
 
-- `ctx.sessionProjections.register(definition): () => void` Register one domain's unit. Duplicate keys and invalid `stateVersion` throw; the registration is an effect on the calling fiber, so an unloaded domain plugin's key (with its cached cells) disappears from subsequent drives and snapshots — clients read that as capability absence.
-- `ctx.sessionProjections.onChanged(listener): () => void` Subscribe to the change feed: one call per client-visible unit whose state reference changed, per committed event, carrying the schema-validated view and the causing seq. Effect-tied like `register`.
-- `ctx.sessionProjections.stateOf(session, key)` Read one registered unit's current host state without computing unrelated views. The returned value is a live read-only reference; callers must not mutate it.
-- `ctx.sessionProjections.snapshot(session): ProjectionSnapshot` One consistent synchronous cut over every registered client-visible unit — `{ asOfSeq, values }` with `asOfSeq` = the seq of the last event every value reflects (`-1` for an empty log). Host-only state is available only through `stateOf`.

-### Key Types
+-----
 
-- `SessionProjectionMap` — the merge-extensible client-view table shared by wire blocks and client hooks. Values are wire-JSON whole values; rendering belongs to the slot system, never this layer.
-- `SessionProjectionStateMap` — the merge-extensible host fold-state table. Every client-visible key appears in both tables; host-only keys appear only here.
-- `ProjectionDefinition<K, S>` — `{ key, stateSchema, init(), apply(state, event), wire?, stateVersion }`: a synchronous state-driven computation unit. `wire` supplies `viewSchema` and `view`; omitting it makes the unit host-only.
+<a id="use-this-package"></a>
+## Use this package
 
-## Contract
+Mount `dsh-session-projection` wherever client carriers need current values of log-derived session state. Domain plugins register units; carriers read snapshots and subscribe to the change feed; neither knows the other.
 
-- **The framework drives, the domain computes.** The registry subscribes to `session/event` once; every committed event passes every unit's `apply` eagerly. Domains hold no subscriptions. Cells (`{state, observedSeq}` per unit per session, WeakMap-keyed) build lazily — a unit registered after events flowed, or a read of a session predating the registration, folds `init` over the in-memory log on first touch.
-- **Same-reference means no work.** `apply` MUST return the same state reference for events that do not concern the unit; the drive gates the change feed on `Object.is`, so non-matching events cost one call and nothing downstream.
-- **Whole-value event rule (load-bearing).** A state-carrying log event MUST carry the complete post-change state, never a bare delta — it keeps every transition trivially cheap and every served value self-describing (last-wins for consumers).
-- **Synchronous unit discipline.** `init`/`apply`/`wire.view` MUST be synchronous; carriers read `snapshot()` in the same tick as their page slice, which is what makes `asOfSeq` one consistent cut. An accidentally async view returns a Promise, which fails `wire.viewSchema.parse`.
-- **State is validated plain JSON, `stateVersion` is its invalidation anchor.** The persisted projection cache stores `(sessionId, key, ver, seq, val)` rows and validates `val` with `stateSchema` before use; bump `stateVersion` whenever the state fields or fold semantics change. Every unit's state is checkpointed — client-visible and host-only alike.
-- **No wire vocabulary here.** The registry exposes only the change feed and the snapshot read face; carriers (api-proxy) mint their own frames (`session/projection`) and blocks from them.
-- **Optional capability.** Domain plugins register under `ctx.inject(['sessionProjections'], …)` so headless assemblies without the registry stay unaffected; carriers use `ctx.get('sessionProjections')` and omit their block/frames entirely when the registry is absent.
+### When to choose it
 
-## Role
+Choose it when a domain keeps state that clients should see without re-deriving it — a todo list, a goal snapshot, conversation statistics. The registry drives units eagerly over committed events, so any registered unit's value is current by construction. Skip it for host-only bookkeeping that no client reads: a unit without a `wire` block stays host-only, and headless assemblies without the registry are unaffected.
 
-This package owns the Service Definition and drive roles of the capability seam: domain host plugins (e.g. `dsh-tool-todo`) contribute units, carriers (`dsh-host-apiproxy`) consume the snapshot and change feed, and neither knows the other.
+### Define a projection unit
 
+A domain contributes one `ProjectionDefinition` per state key: a key, a state schema, an initial state, a synchronous fold `apply(state, event)`, an optional `wire` block that projects state to a client view, and a `stateVersion` that bumps whenever the state fields or fold semantics change:
+
+```text
+const definition = {
+  key: 'todo',
+  stateSchema: todoStateSchema,
+  stateVersion: 1,
+  init: () => ({ items: [] }),
+  apply: (state, event) => event.type === 'todo/upsert'
+    ? { items: event.data.items }
+    : state,
+  wire: {
+    viewSchema: todoViewSchema,
+    view: state => ({ items: state.items }),
+  },
+}
+```
+
+`apply` must be synchronous and must return the same state reference for events that do not concern the unit — an unchanged reference means zero downstream work. A state-carrying log event must carry the complete post-change state, never a bare delta.
+
+### Register and read
+
+`register(definition)` installs the unit; the registration is an effect on the calling fiber, so unloading the domain removes its key. Carriers read a consistent synchronous cut over every client-visible unit with `snapshot(session)` — `{ asOfSeq, values }`, where `asOfSeq` is the seq of the last event every value reflects — and subscribe to per-change notifications with `onChanged(listener)`. `stateOf(session, key)` reads one unit's host state without computing unrelated views.
+
+```text
+const dispose = ctx.sessionProjections.register(definition)
+const { asOfSeq, values } = ctx.sessionProjections.snapshot(session)
+```
+
+### Persisted checkpoints
+
+Every unit's state is checkpointed — client-visible and host-only alike — through `checkpoint(session)`, and the sibling [session-projection-cache](../session-projection-cache/README.md) persists those checkpoints so cold reads skip full log loads. `restoreFloor` and `restore` implement the read recipe (cached state plus a forward tail replay) without a live session.

+
+### Design concept
+
+The package is the Service Definition and drive role of a capability seam: the framework drives, the domain computes. The registry subscribes to `session/event` once; every committed event passes every registered unit's `apply` eagerly (cells build lazily on first touch). The change feed is gated on `Object.is` — a unit that returns the same state reference costs one call and nothing downstream. Carriers read `snapshot()` in the same tick as their page slice, which is what makes `asOfSeq` one consistent cut; an accidentally async view returns a Promise and fails `wire.viewSchema.parse`.

+
+### Drive and checkpoint flow
+
+One committed event drives every registered unit in registration order; a changed client-visible unit notifies the change feed with its schema-validated view and the causing seq. `checkpoint(session)` returns one detached `(key → {ver, seq, val})` row per unit for the persisted cache; `restoreFloor` anchors a tail read one event below the lowest usable watermark so a shrunk log is detected, and `restore` refolds persisted rows over a stored suffix, discarding any row whose `ver` does not match or that claims events past the stored end.

 ## Known Limitations and Deferred Work
 
-- **Every tail page carries every client-visible key** — there is no per-key opt-out or lazy-key request shape yet; acceptable while values are UI-scale whole states (a todo list, a goal snapshot), revisit if a domain's value grows large.
-- **The unit table is process-wide, so key presence is not a per-session capability signal** — a key registered by ANY agent preset appears in every session's snapshot, including sessions whose own composition mounts nothing that produces it. A client must read the VALUE (`plan.active`, an empty todo list) rather than treat an absent key as absence of the feature; a unit whose empty value is indistinguishable from a real one belongs on the host plane instead, which is why `dsh-token-meter` sits there.
-- **Eager drive touches every unit per event** — cheap by construction (whole-value rule, same-reference gate), but a hot path would justify per-unit event-type prefilters, addable without contract change.

-会话投影 Service Definition 与驱动注册表。它拥有 `ctx.sessionProjections`：该注册表在已提交的会话事件上驱动每个已注册的投影单元，并向载体提供完整的最终值，目前包括 api-proxy 历史尾页和 `session/projection` 推送帧。领域注册的只是纯数学；驱动权归框架。[session-projection RFC](../../../.agents/notes/proposed/architecture/2026-07-27-session-projection-and-command-log.zh.md) 记录了设计理由。
+## 概述
 
-## 服务：`SessionProjectionRegistry`（ctx 键：`sessionProjections`）
+`dsh-session-projection` 向客户端载体提供日志派生的逐会话状态的完整当前值——历史尾页与 `session/projection` 推送帧：一个注册表（`ctx.sessionProjections`）把每个已提交会话事件折叠到已注册投影单元并对外提供所得值。领域注册一个纯计算单元（初始状态、对事件的折叠与可选客户端视图）；框架负责订阅、驱动与变更通知，因此领域不持有任何订阅，客户端收到的是成品值，绝不自行折叠事件。每个被提供的值都是经 schema 校验的纯 JSON，逐单元 `stateVersion` 锚定持久缓存的失效。当客户端需要派生的逐会话状态——todo 清单、goal 快照、对话统计——而不想自己折叠原始日志时，选择本包。
 
-### 公开 API
+## 目录
 
-- `ctx.sessionProjections.register(definition): () => void` 注册一个领域的单元。key 重复或 `stateVersion` 非法都会 throw；注册是挂在调用方 fiber 上的 effect，领域插件卸载后其 key（连同缓存的 cell）从后续驱动与快照中消失——客户端将其读作能力缺失。
-- `ctx.sessionProjections.onChanged(listener): () => void` 订阅变更流：每个已提交事件、每个状态引用发生变化的客户端可见单元各回调一次，携带经 schema 校验的 view 与致因 seq。与 `register` 一样绑定 effect。
-- `ctx.sessionProjections.stateOf(session, key)` 读取一个已注册单元的当前 host 状态，不计算无关 view。返回值是活的只读引用；调用方不得修改。
-- `ctx.sessionProjections.snapshot(session): ProjectionSnapshot` 对全部已注册客户端可见单元做一次一致的同步切面——`{ asOfSeq, values }`，其中 `asOfSeq` = 所有值共同反映到的最后一个事件的 seq（空日志为 `-1`）。host-only 状态只能通过 `stateOf` 读取。

-- `SessionProjectionStateMap`——merge-extensible host 折叠状态表。每个 client-visible key 同时出现在两个表中；host-only key 只出现在这里。

+<a id="use-this-package"></a>
+## 使用本包
 
-## 约定
+在客户端载体需要日志派生会话状态的当前值处挂载 `dsh-session-projection`。领域插件注册单元；载体读取快照并订阅变更流；两侧互不相识。
 
-- **框架负责驱动，领域负责计算。** 注册表只订阅一次 `session/event`；每个已提交事件都会主动经过每个单元的 `apply`。领域不持有任何订阅。cell（每会话每单元一份 `{state, observedSeq}`，以 WeakMap 为键）惰性构建——在事件流过之后才注册的单元，或读取一个早于该注册的会话，都在首次触达时从 `init` 出发在内存日志上折叠。
-- **同引用即无工作。** 对与单元无关的事件，`apply` 必须返回同一个状态引用；驱动以 `Object.is` 把守变更流，因此不匹配的事件只花一次调用，不产生任何下游工作。
-- **全量值事件规则（承重）。** 携带状态的日志事件必须携带变更后的完整状态，绝不携带裸增量——这让每次状态转移始终足够廉价，也让每个被供给的值自描述（对消费方即 last-wins）。
-- **单元的同步纪律。**`init`/`apply`/`wire.view` 必须是同步的；载体在切出页面切片的同一 tick 内读取 `snapshot()`，`asOfSeq` 之所以是一个一致切面正系于此。误写成异步的 view 会返回 Promise，并被 `wire.viewSchema.parse` 拒绝。
-- **状态是经校验的纯 JSON，`stateVersion` 是其失效锚点。** 持久投影缓存存储 `(sessionId, key, ver, seq, val)` 行，并在使用前以 `stateSchema` 校验 `val`；状态字段或折叠语义一旦变化就递增 `stateVersion`。每个单元的状态都会被检查点化——client-visible 与 host-only 一视同仁。
-- **本层没有协议词汇。** 注册表只暴露变更流与快照读取面；载体（api-proxy）据此自铸各自的帧（`session/projection`）与块。
-- **可选能力。** 领域插件在 `ctx.inject(['sessionProjections'], …)` 下注册，因此不带注册表的 headless 组装完全不受影响；载体使用 `ctx.get('sessionProjections')`，注册表缺席时完全省略自己的块与帧。
+### 何时选择
 
-## 职责
+当领域保存客户端应看到、但不应自行重新派生的状态——todo 清单、goal 快照、对话统计——时选择本包。注册表在已提交事件上主动驱动单元，因此任何已注册单元的值按构造即为当前值。当维护的是无客户端读取的 host-only 记账时跳过：不带 `wire` 块的单元保持 host-only，而不带注册表的 headless 组装不受影响。
 
-本包承担能力 seam 的 Service Definition 与驱动角色：领域 host 插件（如 `dsh-tool-todo`）贡献单元，载体（`dsh-host-apiproxy`）消费快照与变更流，两侧互不相识。
+### 定义投影单元
 
+领域为每个状态键贡献一个 `ProjectionDefinition`：一个 key、状态 schema、初始状态、同步折叠 `apply(state, event)`、可选的 `wire` 块（把状态投影为客户端视图），以及状态字段或折叠语义变化时递增的 `stateVersion`：
+
+```text
+const definition = {
+  key: 'todo',
+  stateSchema: todoStateSchema,
+  stateVersion: 1,
+  init: () => ({ items: [] }),
+  apply: (state, event) => event.type === 'todo/upsert'
+    ? { items: event.data.items }
+    : state,
+  wire: {
+    viewSchema: todoViewSchema,
+    view: state => ({ items: state.items }),
+  },
+}
+```
+
+`apply` 必须同步，且对与单元无关的事件必须返回同一个状态引用——引用不变意味着零下游工作。携带状态的日志事件必须携带变更后的完整状态，绝不携带裸增量。
+
+### 注册与读取
+
+`register(definition)` 安装单元；注册是挂在调用方 fiber 上的 effect，因此卸载领域即移除其 key。载体用 `snapshot(session)` 对每个客户端可见单元读取一致的同步切面——`{ asOfSeq, values }`，其中 `asOfSeq` 是所有值共同反映到的最后一个事件的 seq——并用 `onChanged(listener)` 订阅逐变更通知。`stateOf(session, key)` 读取一个单元的主机状态，不计算无关视图。
+
+```text
+const dispose = ctx.sessionProjections.register(definition)
+const { asOfSeq, values } = ctx.sessionProjections.snapshot(session)
+```
+
+### 持久检查点
+
+每个单元的状态都会被检查点化——client-visible 与 host-only 一视同仁——通过 `checkpoint(session)`，同级包 [session-projection-cache](../session-projection-cache/README.zh.md) 持久化这些检查点，使冷读跳过全量日志加载。`restoreFloor` 与 `restore` 在无活动会话的情况下实现读取配方（缓存状态加正向尾部回放）。

+
+本节说明驱动机制与单元约定；可观察约定已在[使用本包](#use-this-package)中说明。
+
+### 设计理念
+
+本包是能力 seam 的 Service Definition 与驱动角色：框架负责驱动，领域负责计算。注册表只订阅一次 `session/event`；每个已提交事件都会主动经过每个已注册单元的 `apply`（cell 在首次触达时惰性构建）。变更流以 `Object.is` 把关——返回同一状态引用的单元只花一次调用，不产生任何下游工作。载体在切出页面切片的同一 tick 内读取 `snapshot()`，`asOfSeq` 之所以是一个一致切面正系于此；误写成异步的 view 会返回 Promise，并被 `wire.viewSchema.parse` 拒绝。

+
+### 驱动与检查点流程
+
+一个已提交事件按注册顺序驱动每个已注册单元；状态引用变化的客户端可见单元会以经 schema 校验的视图与致因 seq 通知变更流。`checkpoint(session)` 为持久缓存返回每个单元一份独立的 `(key → {ver, seq, val})` 行；`restoreFloor` 把尾部读取锚定在最低可用水位之前一个事件处，使缩短的日志可被检出；`restore` 把持久行在存储后缀上重新折叠，丢弃任何 `ver` 不匹配或声称越过存储末尾的行。

-Function plugin registering the `sessionStats` projection unit: whole-log conversation figures — turn/step counts and the LLM, tool, first-token, and decode wall times — folded from step boundaries, stream chunks, tool pairs, and assembled assistant messages, and served through the session-projection seam (registry snapshot, change feed, and every projection carrier: history tail page, `session/projection` push frames, session list rows). Clients render full-session figures that paging and compaction cannot change; the reference consumer is the web chat stats strip, whose window fold mirrors these field names as its no-unit fallback.
+## Summary
 
-## Fold semantics
+`dsh-session-stats` serves whole-log conversation figures — turn and step counts plus LLM, tool, first-token, and decode wall times — as the `sessionStats` projection unit. Clients read the figures from the registry's snapshot and change feed, and paging or compaction cannot change them because they fold from the complete durable log. Choose it in compositions that already mount the projection registry, such as the web chat bundle whose stats strip is the reference consumer; assemblies without the registry are unaffected and their consumers fall back to window-scoped counting. Setup and field semantics come first; the fold internals live in a collapsible developer section below.
 
-- `steps` counts `step/end` events. The agent loop appends exactly one per entered step, in a `finally`, so completed, failed, cancelled, and max-tokens steps all count. Counting assembled assistant messages instead would overcount max-tokens usage-host messages (empty content, excluded from the surface) and undercount cancelled steps (aborted before the message assembles).
-- `turns` counts distinct turns carrying at least one closed step; rejected or empty turns (closed with no step) are uncounted. Turn numbers are host-assigned and monotonic per session, so the fold keeps only the last counted turn.
-- `llmMs` sums `step/start` → `assistant/message` per step that assembled a message (retry waits inside the step are model time, as in the window fold).
-- `ttftMs`/`ttftSteps` sum and count `step/start` → first non-empty delta chunk; the first attempt's boundary survives an in-step `llm/retry` (window `resetForRetry` parity).
-- `decodeMs`/`decodeTokens` sum first token → assembled message and the provider-reported output tokens, only over steps carrying both.
-- `toolMs` sums `tool/call` → `tool/result` pairs matched by callId; unresolved calls are dropped at `turn/end` (results land within their turn).
-- Every field is 0 until its first contributing event. A composed registry always serves the key, so clients read the value, never key presence.

+## Use this package
+
+Mount the plugin beside the session store and the projection registry when clients should display whole-session conversation figures that survive paging and compaction. The unit registers only when the registry is present.
+
+### Composition
 
 ```yaml
-- id: session-stats
-  name: '@deepseek-ai/dsh-session-stats'
+- name: '@deepseek-ai/dsh-session'
+- name: '@deepseek-ai/dsh-session-projection'
+- name: '@deepseek-ai/dsh-session-stats'
 ```
 
-Injects `sessionProjections` — the plugin's whole purpose; in assemblies without the registry the fiber stays pending and nothing registers.
+### What the figures mean
 
+| Field | Meaning |
+|---|---|
+| `turns` | Distinct turns with at least one closed step; rejected or empty turns are uncounted |
+| `steps` | Closed steps — completed, failed, cancelled, and max-tokens steps all count |
+| `llmMs` | Summed model wall time over steps that assembled a message |
+| `toolMs` | Summed matched `tool/call` → `tool/result` wall time |
+| `ttftMs` / `ttftSteps` | Summed first-token latency and the steps carrying it |
+| `decodeMs` / `decodeTokens` | Summed decode wall time and provider output tokens over usage-reporting steps |
+
+Every field is 0 until its first contributing event; the composed registry always serves the key, so clients read the value rather than key presence. Clients render whole-log figures through the projection seam's snapshot and change feed; the reference consumer is the web chat stats strip, whose window fold mirrors these field names as its no-unit fallback.
+
+### Failures and recovery
+
+The unit is inert without the projection registry: `inject` keeps the fiber pending and nothing registers, so other assemblies lack the `sessionStats` key. Unmounting the plugin removes the key, because registrations are effects on the mounting fiber. A crash-interrupted step counts after the session reloads, when crash recovery appends its synthetic `step/end`.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the fold behind the figures; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The unit is a pure fold over committed session events: `step/end` is the counted step event because the agent loop appends exactly one per entered step in a `finally`, so completed, failed, cancelled, and max-tokens steps all land one. Counting assembled assistant messages instead would overcount max-tokens usage-host messages (empty content, excluded from the surface) and undercount cancelled steps (aborted before the message assembles). The wall-time folds mirror the client window fold field by field.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `inject`, unit registration on the mounting fiber |
+| [`src/projection.ts`](src/projection.ts) | The fold: state shape, per-event transitions, wire view |
+| [`src/types.ts`](src/types.ts) | One home of the `sessionStats` projection-key declaration and field types |
+
+### Data model
+
+The fold state holds the eight totals plus in-flight boundaries: `lastTurn` (turn of the last counted `step/end`), `openStep` (the open step's boundary facts, closed by its `assistant/message`), and `pendingCalls` (tool dispatch times by callId). The wire view is a strict subset — the eight totals — so the persisted-cache state schema extends the view schema with the boundary fields.
+
+### Fold rules
+
+- Uninteresting events return the same state reference; the registry's `Object.is` gate keeps the change feed quiet.
+- First-token latency records the first non-empty delta chunk and survives an in-step `llm/retry`.
+- Decode time and tokens accrue only over steps carrying both a first token and a valid provider usage report; malformed usage is ignored like the window fold guards node usage.
+- Tool time pairs `tool/call` → `tool/result` by callId; unresolved calls are dropped at `turn/end` because results land within their turn, and a callId colliding with an `Object` prototype name reads as unmatched.

 ## Model Experience
 
-None, as the plugin only computes a client-facing read model of already-logged session events and touches no prompt, message, schema, stream, or tool result.
+None, as the sessionStats unit folds already-logged step boundaries into a client-facing read model and registers nothing model-facing.
 
 #### KV Cache effect
 
-None; the plugin never assembles or sends provider requests.
+None; the package never assembles or sends provider requests.
 
 ## Known Limitations and Deferred Work
 
-- **Steps count work attempted, not visible output** — a step that failed before producing any visible content still closed with `step/end` and counts; a step interrupted by a crash counts after the session reloads, when crash recovery appends its synthetic `step/end` (`interruptedTurnClosers` in dsh-session).
-- **A cancelled step is counted but untimed** — no assistant message assembles, so its partial stream time enters no wall-time figure, matching the window fold's untimed interrupted node; a max-tokens usage-host message conversely contributes model time the surface does not show.
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define what the figures describe and when the unit is absent. They are current package constraints.

-注册 `sessionStats` projection 单元的函数插件：从步边界、流式 chunk、工具配对与已组装的 assistant 消息折叠出全日志会话数字——轮/步计数以及 LLM、工具、首 token、解码墙钟时间——经 session-projection 缝对外提供（registry 快照、变更流，以及每一个 projection 载体：history 尾页、`session/projection` 推送帧、会话列表行）。客户端由此渲染分页与压缩都无法改变的全会话数字；参考消费者是 Web 聊天统计条，其窗口折叠以相同字段名充当无单元时的回退。
+## 概述
 
-## 折叠语义
+`dsh-session-stats` 提供全日志会话数字——轮/步计数以及 LLM、工具、首 token、解码墙钟时间——以 `sessionStats` 投影单元的形式对外提供。客户端从注册表的快照与变更流中读取数字，且由于它们从完整持久日志折叠而来，分页或压缩都无法改变它们。在已挂载投影注册表的组合中选择它，例如 Web 聊天包（其统计条是参考消费者）；没有注册表的装配不受影响，其消费者回退到窗口口径计数。设置与字段语义在前；折叠内部细节放在下方可折叠的开发者章节中。
 
-- `steps` 统计 `step/end` 事件。agent loop 对每个进入的步在 `finally` 中恰好追加一条，因此完成、失败、取消、max-tokens 的步全部计入。若改按已组装的 assistant 消息计数，则会多算 max-tokens 的 usage 宿主消息（空内容、被排除在 surface 之外），并少算被取消的步（在消息组装前已中止）。
-- `turns` 统计含至少一个已关闭步的不同 turn；被拒绝或空轮（未进入任何步即关闭）不计。turn 号由宿主分配、按会话单调递增，因此折叠只需保留最近计入的 turn。
-- `llmMs` 按步累加 `step/start` → `assistant/message`（组装出消息的步；步内重试的等待与窗口折叠一样计入模型时间）。
-- `ttftMs`/`ttftSteps` 累加并统计 `step/start` → 首个非空 delta chunk；首次尝试的边界在步内 `llm/retry` 后保留（与窗口 `resetForRetry` 对齐）。
-- `decodeMs`/`decodeTokens` 累加首 token → 已组装消息的时长与提供方上报的输出 token，仅统计两者兼备的步。
-- `toolMs` 按 callId 配对累加 `tool/call` → `tool/result`；未解决的调用在 `turn/end` 时丢弃（结果总在其轮内落地）。
-- 每个字段在首个贡献事件之前均为 0。已装配的 registry 恒提供该键，客户端读取值本身，而非键的存在性。

+## 使用本包
+
+当客户端需要显示不受分页与压缩影响的全会话数字时，在会话存储与投影注册表旁挂载此插件。只有存在注册表时单元才会注册。
+
+### 组合
 
 ```yaml
-- id: session-stats
-  name: '@deepseek-ai/dsh-session-stats'
+- name: '@deepseek-ai/dsh-session'
+- name: '@deepseek-ai/dsh-session-projection'
+- name: '@deepseek-ai/dsh-session-stats'
 ```
 
-注入 `sessionProjections`——这是插件的全部用途；在没有 registry 的装配中 fiber 保持挂起，不注册任何内容。
+### 各字段含义
 
+| 字段 | 含义 |
+|---|---|
+| `turns` | 含至少一个已关闭步的不同轮次；被拒绝或空轮不计 |
+| `steps` | 已关闭的步——完成、失败、取消与 max-tokens 的步全部计入 |
+| `llmMs` | 组装出消息的步的模型墙钟时间之和 |
+| `toolMs` | 匹配的 `tool/call` → `tool/result` 墙钟时间之和 |
+| `ttftMs` / `ttftSteps` | 首 token 延迟之和及其承载步数 |
+| `decodeMs` / `decodeTokens` | 上报用量的步的解码墙钟时间与提供方输出 token 之和 |
+
+每个字段在首个贡献事件之前均为 0；已装配的注册表恒提供该键，因此客户端读取值本身，而非键的存在性。客户端通过投影 seam 的快照与变更流渲染全日志数字；参考消费者是 Web 聊天统计条，其窗口折叠以相同字段名充当无单元时的回退。
+
+### 失败与恢复
+
+没有投影注册表时单元是惰性的：`inject` 使 fiber 保持挂起，不注册任何内容，因此其他装配缺少 `sessionStats` 键。卸载插件会移除该键，因为注册是挂载 fiber 上的 effect。被崩溃打断的步在会话重新加载后计入，届时崩溃恢复补写合成的 `step/end`。

+本节解释数字背后的折叠；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+该单元是对已提交会话事件的纯折叠：`step/end` 是被计数的步事件，因为 agent loop 对每个进入的步在 `finally` 中恰好追加一条，因此完成、失败、取消与 max-tokens 的步都会落地一条。若改按已组装的 assistant 消息计数，则会多算 max-tokens 的 usage 宿主消息（空内容、被排除在 surface 之外），并少算被取消的步（在消息组装前已中止）。墙钟折叠逐字段对齐客户端窗口折叠。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：`inject`、在挂载 fiber 上注册单元 |

+| [`src/types.ts`](src/types.ts) | `sessionStats` 投影键声明与字段类型的唯一归属 |
+
+### 数据模型
+
+折叠状态保存八个总计外加进行中的边界：`lastTurn`（最近一次被计数 `step/end` 的轮次）、`openStep`（打开步的边界事实，由其 `assistant/message` 关闭）与 `pendingCalls`（按 callId 记录的工具分发时间）。wire 视图是严格子集——八个总计——因此持久缓存的状态 schema 以边界字段扩展视图 schema。
+
+### 折叠规则
+
+- 不相关事件返回同一状态引用；注册表的 `Object.is` 门禁保持变更流安静。
+- 首 token 延迟记录首个非空 delta chunk，并在步内 `llm/retry` 后保留。
+- 解码时间与 token 只在同时携带首 token 与有效提供方用量报告的步上累加；与窗口折叠守卫节点用量一样忽略畸形用量。
+- 工具时间按 callId 配对 `tool/call` → `tool/result`；未解决的调用在 `turn/end` 时丢弃，因为结果总在其轮内落地，而撞上 `Object` 原型名的 callId 读作未匹配。

-The OpenTelemetry backend for [the telemetry seam](../session-telemetry/) — the only entry a deployment loads. Its `mode` decides whether the seam follows session events live, replays the canonical log only at recorded feedback, or keeps telemetry local. Uploading modes compose the OTel JS SDK as-is (`LoggerProvider` → `BatchLogRecordProcessor` → OTLP/HTTP log exporter) and map each handed-over record onto `logger.emit()`, under two instrumentation scopes: ledger records on `@deepseek-ai/dsh-session-sessionTelemetry-otel`, operational records on `@deepseek-ai/dsh-session-sessionTelemetry-otel/ops`. Resource identity contains `service.name`/`service.version` from `dsh-llm`'s `APP_IDENTITY` plus this package's anonymous `user.id` (`$DSH_HOME/.anonymous-user-id`, a random UUID created on first use and reset by deleting the file), carried once per export batch rather than per record.
+## Summary
 
-## Config
+`dsh-session-telemetry-otel` delivers session records through OpenTelemetry logs and is the only entry a deployment loads for the [session-telemetry seam](../session-telemetry/README.md). Its `mode` decides whether session records follow the live stream, are released only at recorded feedback, or stay local: `FULL` hands every record to the OTel SDK immediately, `FEEDBACK_ONLY` replays the canonical log when a `feedback/record` lands, and `DISABLED` (the default) constructs nothing and shares nothing. Uploading modes compose the OTel JS SDK as-is — `LoggerProvider` → `BatchLogRecordProcessor` → OTLP/HTTP log exporter — and map each record onto `logger.emit()`, so batching, retry, queueing, and loss policy follow the SDK. Records carry the complete event data as the seam's redaction waterfall returns it, so a deployment exporting beyond a trusted boundary mounts its own redaction rules. Modes, configuration, and the export surface come first; the implementation internals live in a collapsible developer section below.

+## Use this package
+
+Mount this plugin when a deployment should export session records through OpenTelemetry logs. Choose a mode, give the exporter an endpoint, and decide whether to mount redaction rules on the seam.
+
+### Modes
+
+| `mode` | Behavior |
+|---|---|
+| `FULL` | Every projected record, including lifecycle ops records, is handed to the OTel SDK immediately |
+| `FEEDBACK_ONLY` | Each `feedback/record` replays, projects, and redacts the canonical session-log suffix through that event; later records wait for another feedback event and remain local if none arrives |
+| `DISABLED` | Default. No coordinator, provider, processor, or exporter is constructed; no telemetry record leaves the process, and a `feedback/record` logs that nothing will be shared |
+
+Programmatic TypeScript configuration uses the exported `SessionTelemetryMode` enum; raw string literals are not assignable. The mounted service discloses the resolved mode through the seam's [`SessionTelemetrySharingStatus`](../session-telemetry/README.md#the-sharing-disclosure) `sharing` property (`full` / `feedback-only` / `disabled`), so the `/feedback` acknowledgement reports whether and how the session is shared — even `DISABLED` discloses `disabled`.
+
+### Minimal configuration
+
+Uploading modes require an exporter URL and accept the SDK option blocks verbatim:
 
 ```yaml
 - id: sessionTelemetry-otel
-  name: '@deepseek-ai/dsh-session-sessionTelemetry-otel'
+  name: '@deepseek-ai/dsh-session-telemetry-otel'
   config:

-| `mode` | Behavior |
+| Field | Default | Meaning |
+|---|---|---|
+| `mode` | `DISABLED` | Sharing policy: `FULL`, `FEEDBACK_ONLY`, or `DISABLED` |
+| `exporter.url` | required in uploading modes | Full OTLP logs endpoint; must parse as `http(s)` |
+| `exporter`, `processor` | — | Passed verbatim to the SDK exporter and batch processor |
+| `shutdownTimeoutMillis` | `3,000` | Outer deadline for the SDK's complete shutdown sequence |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-session-telemetry-otel) is the exhaustive source for every accepted field. Upload authorization is positive and fail-closed: an unknown direct-construction mode fails before transport configuration is read, only `FULL` accepts direct `ctx.sessionTelemetry.emit()` calls, and `FEEDBACK_ONLY` treats only the exact `feedback/record` object already stored in the canonical log as consent.
+
+### What leaves the machine
+
+In uploading modes, records carry the complete `event.data` as the seam's `sessionTelemetry/record` waterfall returns it — message content, tool arguments and results, the system prompt and tool schemas, todo text, compaction summaries, feedback text, and the session `cwd`. Provider credentials never appear: adapter API keys are constructor parameters, not session events, so they are structurally absent from the log and therefore from telemetry. `DISABLED` constructs no SDK pipeline and hands no capture to a backend.
+
+### Failures and shutdown
+
+Misconfiguration fails at plugin load: a missing or non-`http(s)` `exporter.url`, a non-positive-integer `processor.maxExportBatchSize` (which the SDK accepts but then hangs on at shutdown), and an invalid `shutdownTimeoutMillis` all reject before any record is exported. During shutdown, OTel awaits `exporter.forceFlush()` before the processor's bounded completion promise; if that transport promise never settles, this package abandons the wait at `shutdownTimeoutMillis`, logs the contained failure, and lets application teardown continue — records still pending then may be lost at process exit.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the backend's composition; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The backend is a thin adapter over the OTel JS SDK: it owns capture mode, resource identity, and an outer shutdown deadline, and passes everything else through verbatim. Two instrumentation scopes separate record channels — ledger records on `@deepseek-ai/dsh-session-telemetry-otel`, operational records on `@deepseek-ai/dsh-session-telemetry-otel/ops` — so receivers can alert on ops without summing them. Resource identity carries `service.name`/`service.version` from `dsh-llm`'s `APP_IDENTITY` plus the package's anonymous `user.id` (from `$DSH_HOME/.anonymous-user-id`), once per export batch rather than per record.
+
+### Source map
+
+| File | Role |
 |---|---|
-| `FULL` | Each projected record, including lifecycle ops records, is handed to the OTel SDK immediately. |
-| `FEEDBACK_ONLY` | Each `feedback/record` replays, projects, and redacts the canonical session-log suffix through that event. Later records wait for another feedback event and remain local if none arrives. |
-| `DISABLED` | Default. No coordinator, provider, processor, or exporter is constructed. No telemetry record leaves the process. A `feedback/record` logs `session sessionTelemetry is DISABLED; nothing will be shared and this feedback remains local`; the event remains in the local session log. |
+| [`src/index.ts`](src/index.ts) | Plugin entry: mode resolution, fail-closed validation, SDK pipeline wiring, coordinator composition, shutdown deadline |
 
-Programmatic TypeScript configuration uses the exported `SessionTelemetryMode` enum (`SessionTelemetryMode.FULL`, `SessionTelemetryMode.FEEDBACK_ONLY`, or `SessionTelemetryMode.DISABLED`); raw string literals are not assignable. Serialized Cordis configuration continues to use the string values shown above.
+### Capture wiring
 
-Upload authorization is positive and fail-closed. An unknown direct-construction mode fails before transport configuration is read. Only `FULL` accepts direct `ctx.sessionTelemetry.emit()` calls. `FEEDBACK_ONLY` gives its on-demand coordinator a private backend capability and treats only the exact `feedback/record` object already stored at `session.events[event.seq]` as consent; an independently emitted bus value is ignored. `DISABLED` never constructs the SDK pipeline, even when exporter options are present.
+`FULL` composes the coordinator in `live` mode and lets direct service calls through; `FEEDBACK_ONLY` composes it in `on-demand` mode, gives the coordinator a private backend capability, and triggers `captureSession(session, event.seq)` only for the exact canonical feedback record; `DISABLED` registers nothing but a warning on `feedback/record`. The backend deliberately implements no `flush()`: the batch processor owns ordinary flushing, and forwarding the hint to `forceFlush()` would create the sole source of concurrent flushes whose interaction with shutdown's drain is undocumented.
 
-The mounted service discloses the resolved mode through the seam's [`SessionTelemetrySharingStatus`](../session-telemetry/README.md#the-sharing-disclosure) `sharing` property (`full` / `feedback-only` / `disabled`), so the `/feedback` acknowledgement can report whether and how the session is shared. The disclosure is set in the constructor and is independent of capture: even `DISABLED` discloses `disabled`.
+### Field mapping
 
-`exporter.url` is required in `FULL` and `FEEDBACK_ONLY`, has no default, and must parse as `http(s)`; it is optional and unused in `DISABLED`. In uploading modes, `shutdownTimeoutMillis` is a positive finite DSH-owned outer deadline that defaults to 3000 ms, and a non-positive-integer `processor.maxExportBatchSize` also fails at plugin load because the SDK accepts it but then hangs on shutdown. Both SDK blocks pass through whole: every `OTLPExporterNodeConfigBase` field (`headers`, `timeoutMillis`, `compression`, `keepAlive`, …) reaches the exporter, and batching, export cadence (`scheduledDelayMillis`), retry, queue bounds, and loss policy under sustained failure are SDK behavior tuned through `processor`. The backend implements no `flush()`: the batch processor owns ordinary flushing. During shutdown, OTel awaits `exporter.forceFlush()` before the processor's `exportTimeoutMillis`-bounded completion promise; if that transport promise never settles, this package abandons the wait at `shutdownTimeoutMillis`, logs the contained shutdown failure through the coordinator, and lets application teardown continue. The deadline cannot cancel the SDK transport, so records still pending then may be lost at process exit.
+Each seam record maps onto one SDK log record: `time` and `severity` become the SDK timestamp and severity fields, and `body` and `attributes` carry through verbatim; the exact field mapping lives in [`src/index.ts`](src/index.ts). In `FULL`, receivers can detect crashes by `shutdown`-record absence — the marker is emitted at the session's own disposal or application teardown, and a marker followed by more events is a telemetry reload. In `FEEDBACK_ONLY`, a released prefix normally has no later `shutdown` marker, so its absence is not a crash signal.
 
-## What leaves the machine
+</details>
 
-In uploading modes, records carry the complete `event.data` as the seam's `sessionTelemetry/record` waterfall returns it — user and assistant message content, tool arguments and results (command output, file contents), the full system prompt and tool schemas (`request/header`), todo text, compaction summaries, hook `stderrSummary`, feedback text, and the session `cwd` (a local path). The seam ships no redaction rules: with no `sessionTelemetry/record` listener mounted, that is the raw captured copy, so a deployment exporting beyond a trusted boundary mounts its own rules (see [the seam README](../session-telemetry/README.md#the-redact-waterfall)). `FULL` runs redaction at append time; `FEEDBACK_ONLY` retains no telemetry copy and runs the currently mounted rules when feedback triggers canonical-log replay. Provider credentials never appear regardless: adapter API keys are constructor parameters, not session events, so they are structurally absent from the log and therefore from telemetry. `DISABLED` does not construct the SDK pipeline or hand any capture to a backend.
+-----
 
-## Field mapping
+<a id="further-exploration"></a>
+## Further Exploration
 
-Seam record → SDK log record: `time` → `timestamp`/`observedTimestamp`; `severity` → `severityNumber`/`severityText` (INFO 9 / WARN 13 / ERROR 17); `body` → the structured log body; `attributes` verbatim. Receivers dedupe on `(session.id, event.seq)` and alert on severity. In `FULL`, they may also detect crashes by `shutdown`-record absence: the marker is emitted at the session's own disposal or application teardown, and a marker followed by more events is a telemetry reload. In `FEEDBACK_ONLY`, a released prefix normally has no later `shutdown` marker, so its absence is not a crash signal. Streams are not self-contained across lineage: a resumed session continues its own id's stream from where the previous process left off, and a forked session's stream starts at its inherited boundary — its prefix lives in the parent's stream, stitched via `session.parent_id` + `session.seed_length`. A resumed local log may contain synthetic closers that were never exported; the wire stream stays faithful to records actually handed to the SDK.

+
+### 最小配置

+| `mode` | `DISABLED` | 共享策略：`FULL`、`FEEDBACK_ONLY` 或 `DISABLED` |
+| `exporter.url` | 上传模式必填 | 完整 OTLP 日志端点；必须能解析为 `http(s)` |

+
+### 源码地图
+
+| 文件 | 职责 |
 |---|---|
-| `FULL` | 每条已投影记录都立即交给 OTel SDK，包括生命周期运维记录。 |
-| `FEEDBACK_ONLY` | 每个 `feedback/record` 都会回放权威会话日志中截至该事件的后缀，并进行投影与脱敏。后续记录等待下一个反馈事件；如果没有后续反馈，则留在本地。 |
-| `DISABLED` | 默认值。不构造协调器、提供方、处理器或导出器。没有遥测记录会离开进程。`feedback/record` 会记录 `session sessionTelemetry is DISABLED; nothing will be shared and this feedback remains local`；该事件留在本地会话日志中。 |
+| [`src/index.ts`](src/index.ts) | 插件入口：模式解析、fail-closed 校验、SDK 流水线接线、协调器组装、关闭截止时间 |
 
-程序化 TypeScript 配置使用导出的 `SessionTelemetryMode` 枚举（`SessionTelemetryMode.FULL`、`SessionTelemetryMode.FEEDBACK_ONLY` 或 `SessionTelemetryMode.DISABLED`）；原始字符串字面量不可赋值。序列化后的 Cordis 配置继续使用上表所示的字符串值。
+### 捕获接线
 
-上传授权采用显式许可，且为 fail-closed。通过直接构造传入未知模式时，会在读取传输配置前失败。只有 `FULL` 接受对 `ctx.sessionTelemetry.emit()` 的直接调用。`FEEDBACK_ONLY` 向其按需协调器提供私有后端能力，并且仅在 `feedback/record` 对象已经存储于 `session.events[event.seq]` 且对象身份完全相同时，才将其视为同意；独立发出的总线值会被忽略。即使存在导出器选项，`DISABLED` 也绝不会构造 SDK 流水线。
+`FULL` 以 `live` 模式组装协调器，并放行直接服务调用；`FEEDBACK_ONLY` 以 `on-demand` 模式组装协调器，给协调器一个私有后端能力，并且只对权威日志中精确的反馈记录触发 `captureSession(session, event.seq)`；`DISABLED` 除了在 `feedback/record` 上发出警告外不注册任何内容。后端刻意不实现 `flush()`：常规 flush 由批处理器负责，把提示转发给 `forceFlush()` 会成为并发 flush 的唯一来源，而它与关闭排空的交互没有文档。
 
-已挂载的服务通过 seam 的 [`SessionTelemetrySharingStatus`](../session-telemetry/README.zh.md#the-sharing-disclosure) `sharing` 属性披露解析后的模式（`full` / `feedback-only` / `disabled`），因此 `/feedback` 的确认文本可以报告会话是否以及如何被共享。该披露在构造函数中设置，与采集相互独立：即使 `DISABLED` 也会披露 `disabled`。
+### 字段映射
 
-`exporter.url` 在 `FULL` 与 `FEEDBACK_ONLY` 中必填，无默认值，且必须能解析为 `http(s)`；在 `DISABLED` 中可省略且不使用。在上传模式中，`shutdownTimeoutMillis` 是由 DSH 管理的有限正数外层截止时间，默认值为 3000 ms；`processor.maxExportBatchSize` 不是正整数时也会在插件加载时失败，因为 SDK 会接受该值，随后却在关闭时挂起。两个 SDK 配置块都整体透传（passthrough）：`OTLPExporterNodeConfigBase` 的每个字段（`headers`、`timeoutMillis`、`compression`、`keepAlive` 等）都会到达导出器；批处理、导出节奏（`scheduledDelayMillis`）、重试、队列上限，以及持续失败下的丢失策略，都是通过 `processor` 调节的 SDK 行为。该后端不实现 `flush()`：常规 flush 由批处理器负责。关闭期间，OTel 会先等待 `exporter.forceFlush()`，再等待受处理器 `exportTimeoutMillis` 限制的完成 promise；如果该传输 promise 始终不结算，本包会在 `shutdownTimeoutMillis` 到期时放弃等待，通过协调器记录已隔离的关闭失败，并让应用继续拆卸。该截止时间无法取消 SDK 传输，因此届时仍待处理的记录可能在进程退出时丢失。
+每条 seam 记录映射为一条 SDK 日志记录：`time` 与 `severity` 变为 SDK 的时间戳与严重级别字段，`body` 与 `attributes` 原样照搬；确切字段映射见 [`src/index.ts`](src/index.ts)。在 `FULL` 中，接收端可通过缺少 `shutdown` 记录检测崩溃——该标记在会话自身 dispose（资源释放）或应用关闭时发出，标记之后出现更多事件说明遥测发生了重载。在 `FEEDBACK_ONLY` 中，已释放的前缀通常不包含随后的 `shutdown` 标记，因此缺少该标记不是崩溃信号。
 
-## 哪些数据会离开本机
+</details>
 
-在上传模式中，记录携带完整的 `event.data`，内容以 seam 的 `sessionTelemetry/record` waterfall（瀑布式事件）返回的结果为准：用户与 assistant 消息内容、工具参数与工具结果（命令输出、文件内容）、完整的系统提示词与工具 schema（`request/header`）、todo 文本、压缩（compaction）摘要、钩子的 `stderrSummary`、反馈文本，以及会话 `cwd`（一个本地路径）。seam 不带任何脱敏规则：未挂载 `sessionTelemetry/record` 监听器时，导出的就是捕获原样的副本，因此向可信边界之外导出的部署方要挂载自己的规则（见 [seam README](../session-telemetry/README.zh.md#the-redact-waterfall)）。`FULL` 在追加时运行脱敏；`FEEDBACK_ONLY` 不保留遥测副本，而是在反馈触发权威日志回放时运行当时挂载的规则。无论如何，提供方凭据都不会出现：适配器的 API key 是构造函数参数而非会话事件，因此它们在结构上就不存在于日志中，也就不存在于遥测中。`DISABLED` 不会构造 SDK 流水线，也不会将任何捕获内容交给后端。

-seam 记录 → SDK 日志记录：`time` → `timestamp`/`observedTimestamp`；`severity` → `severityNumber`/`severityText`（INFO 9 / WARN 13 / ERROR 17）；`body` → 结构化日志 body；`attributes` 原样照搬。接收端基于 `(session.id, event.seq)` 去重，并按严重级别告警。在 `FULL` 中，接收端还可通过缺少 `shutdown` 记录检测崩溃：该标记在会话自身 dispose（资源释放）或应用关闭时发出；标记之后出现更多事件，说明遥测发生了重载。在 `FEEDBACK_ONLY` 中，已释放的前缀通常不包含随后的 `shutdown` 标记，因此缺少该标记不是崩溃信号。跨谱系（lineage）的流并不自足：恢复的会话在其自身 id 的流上从上一个进程停止之处继续；fork 出的会话的流从继承边界开始，其前缀位于父会话的流中，由接收端基于 `session.parent_id` + `session.seed_length` 拼接。恢复后的本地日志可能包含从未导出的合成关闭事件；协议流忠实于实际交给 SDK 的记录。

-The telemetry Service Definition declares the `SessionTelemetrySink` contract, and its capture coordinator passes session records to any reporting SDK backend that implements it. Capture can follow live session events or replay a canonical session-log prefix on demand. This package stops after it calls `emit()`: batching, retry, queueing, and loss policy belong to the backend's SDK and are neither specified nor wrapped. Rationale and rejected alternatives: [the revival Agent Note](../../../.agents/notes/implemented/feature/2026-07-23-session-telemetry-otel-revival.md), [feedback-gated delivery](../../../.agents/notes/implemented/feature/2026-08-05-feedback-gated-session-telemetry.md), and [buffer-free feedback replay](../../../.agents/notes/implemented/simplification/2026-08-06-buffer-free-feedback-telemetry.md).
+## Summary
 
-## The backend contract
+`dsh-session-telemetry` captures session activity for outbound reporting: it projects session events into telemetry records, lets a deployment redact them, and hands them to a reporting backend that implements its contract. Deployments do not load this package directly — they load exactly one backend (the shipped OpenTelemetry backend is `dsh-session-telemetry-otel`), which registers `ctx.sessionTelemetry` and composes the capture coordinator. The seam owns capture, redaction, and the sharing disclosure; batching, retry, queueing, and loss policy belong to the backend's SDK and stop at `emit()`. Every mounted backend discloses its deployment-selected sharing policy so acknowledgement surfaces can report whether and how a session is shared. The contract and capture behavior come first; the implementation internals live in a collapsible developer section below.
 
-`SessionTelemetrySink` has three members: `emit(record)` MUST enqueue without blocking because it runs synchronously during `session/event` or explicit canonical-log replay; optional `flush()` is a fire-and-forget hint after a turn ends, and most backends omit it and use their SDK's normal batching schedule; `shutdown()` drains queued records and resolves when the SDK stops, and disposal awaits it. An implementation that provides `flush()` must order concurrent flushes with the final `shutdown()` drain. `SessionTelemetryBackend` registers this API under the `sessionTelemetry` context key; each context accepts one implementation, and a duplicate load throws. A backend constructs `SessionTelemetryCoordinator` with `live` or `on-demand` capture and calls `captureSession(session, throughSeq?)` at its chosen trigger.
+## Table of Contents
 
-The service also carries the required [`SessionTelemetrySharingStatus`](#the-sharing-disclosure) `sharing` member: the deployment-selected sharing policy every backend must disclose to human-facing acknowledgement surfaces (the `/feedback` command's confirmation). A consumer renders "not configured" only when no telemetry service is mounted. The seam owns the vocabulary (`full` | `feedback-only` | `disabled`) so any backend can disclose a policy without depending on the OTel package.

-## The sharing disclosure
+-----
 
-The acknowledgement of a recorded feedback entry reports whether and how the session is shared, read from the mounted backend's `sharing`. A backend sets the property from its deployment configuration: `full` (every event is handed over as it happens), `feedback-only` (nothing is handed over until a `feedback/record` event releases the unreleased prefix through it), or `disabled` (nothing is handed over at all). Consumers map the status onto user-facing copy; the disclosure never claims delivery — handoff is the non-blocking enqueue, and batching, retry, and loss policy stay the backend SDK's.
+<a id="use-this-package"></a>
+## Use this package
 
-## Capture points
+As a deployment, choose a backend, mount it, and add redaction rules when records must not leave the process as captured. As a backend author, implement the three-member contract and compose the coordinator with a capture mode.
 
-In `live` mode the coordinator registers, all through the composing fiber's effects: `session/created` (adopt: record the header, read the log back through the projection from the construction boundary — constructor seeds from fork/resume never re-emit on the firehose and never re-export), `session/event` (project, deep-copy, redact, then hand off; zero I/O), `session/flush` (forward the optional `flush()` hint and return void — the loop's awaited parallel must never wait on telemetry), `session/disposed` (capture the session's `shutdown` operational record at its termination edge, then retire it), `agent/error` (the one live-bus relay; the session event vocabulary intentionally has no operational-error record), a dispose effect (capture shutdown for each still-live session, then await the backend's `shutdown()`; failures warn instead of throwing), and an adoption sweep of `ctx.sessions.list()` (a hot reload does not replay `session/created`). In `on-demand` mode it registers only the dispose effect: `captureSession()` reads the canonical log through an optional inclusive sequence boundary, while flush hints and operational events remain local.
+### Choosing and mounting a backend
 
-## The redact waterfall
+Load exactly one backend plugin; it registers `ctx.sessionTelemetry` with the capture coordinator and its own delivery pipeline, and a duplicate load throws. The mounted backend discloses its sharing policy through the required [`sharing` member](#the-sharing-disclosure), which the `/feedback` acknowledgement renders; a consumer renders "not configured" only when no telemetry service is mounted.
 
-Every record passes the `sessionTelemetry/record` waterfall immediately after projection — the Service Definition's scrubbing extension point. This package ships NO rules of its own: the innermost `next()` passes the record through unchanged, so with no listener mounted records reach the backend exactly as captured, and exported data is precisely as clean as the rules a deployment mounts. Listeners stack by transforming `next()`'s return value; returning without `next()` replaces everything beneath, and a throwing listener withholds that one record fail-closed inside the coordinator's containment. Live capture runs the waterfall at append time; on-demand capture runs it while replaying the canonical log, using the rules mounted at that time. Redaction applies to the outbound copy only; the canonical session log is never rewritten.
+### The backend contract
 
-## The handoff cursor
+A backend implements three members: `emit(record)` must be a non-blocking enqueue because it runs synchronously on the session-event path; optional `flush()` is a fire-and-forget hint after a turn ends, which most backends omit in favor of their SDK's own batching schedule; `shutdown()` drains queued records and resolves when the SDK stops, and disposal awaits it. A backend that implements `flush()` must order concurrent flushes with the final `shutdown()` drain.
 
-A module-scope `WeakMap<Session, seq>` marks the highest seq HANDED OFF (not delivered) per session. Live capture advances it at append time; on-demand capture advances it only while `captureSession()` hands a requested prefix to the backend. An uncaptured prefix remains solely in the canonical log, so a coordinator reload adds no telemetry-owned recovery state. On replay the coordinator re-hands only events past the cursor (events at or below it still rebuild the chunk-projection state); a missing cursor safely degrades to a re-hand from the session's construction boundary (`Session.firstLiveSeq` — seq 0 for a session born in this process), absorbed by receiver-side dedupe on `(session.id, event.seq)`. Constructor seeds never re-export: a resumed session's history shipped from the previous process under the same id, and a fork's inherited prefix lives in the parent's stream (receivers stitch on `session.parent_id` + `session.seed_length`). The accepted cost, consistent with at-most-once delivery: a resume does not backfill records a previous process failed to deliver — a deployment with a backfill requirement needs the deferred outbox, not replay. This is a deliberate, narrow exception to the registrations-are-effects discipline: entries die with their sessions, the value is a monotonic watermark, and losing it is never an error.
+### What gets captured
 
-## The fixed chunk projection
+Capture runs in one of two modes. `live` capture follows session events as they are appended, replays already-live sessions at mount time, and records lifecycle markers; `on-demand` capture reads the canonical session log only when the backend requests a prefix through `captureSession(session, throughSeq?)`. Ledger records mirror session events one to one except for one projection: only the first `assistant/chunk` of each `(turn, step)` ships, so `seq` gaps on the wire are routine and never a loss signal. Each record carries the event's complete data, minimal identity attributes, and a pre-mapped severity (`error` for `tool/result.isError`, `turn/end` error reasons, and `agent-error`; `info` otherwise).
 
-Only the first `assistant/chunk` of each `(turn, step)` ships; the rest are dropped at capture and never advance the cursor. That one chunk is the stream-started signal: `step/start` + first-chunk presence + `assistant/message` presence + the `turn/end` reason distinguish "the request never started" from "the stream died midway" without chunk volume, and time-to-first-token stays computable. Chunk elision makes `seq` gaps routine on the wire — a gap is never a loss signal. Every other event type, including ones merged by plugins this package never heard of, passes through whole.
+### The sharing disclosure
 
-## The logical record
+<a id="the-sharing-disclosure"></a>
 
-`SessionTelemetryRecord`: `channel` (`ledger` | `ops`), `time` (epoch ms), `severity` (pre-mapped: ERROR for `tool/result.isError`, `turn/end` error reasons, and `agent-error`; INFO for other captured records, while `sessionTelemetry/record` policies may assign WARN), identity-only `attributes` (`session.id`, `event.type`, `event.seq`, plus `session.cwd`/`session.parent_id`/`session.seed_length` when the header has them), and the complete deep-copied `event.data` as `body` — post-redaction. Operational records carry `sessionTelemetry.op` (`agent-error` | `shutdown`) and `session.id`, and deliberately NO `event.seq`/`event.type` — signals to alert on, not entries to sum; `agent-error` normalizes its arbitrary thrown value into a stable `{ name, message }` body. Delivery downstream of the handoff is the backend SDK's; duplicates remain possible (cursor-less re-adoption, SDK retries), so receivers dedupe on `(session.id, event.seq)`.
+Every backend discloses its deployment-selected sharing policy through the seam's `sharing` vocabulary: `full` (every event is handed over as it happens), `feedback-only` (nothing is handed over until a `feedback/record` event releases the unreleased prefix), or `disabled` (nothing is handed over at all). The acknowledgement of a recorded feedback entry reports this status; the disclosure never claims delivery — handoff is the non-blocking enqueue, and batching, retry, and loss policy stay the backend SDK's.
 
+### Redacting records
+
+<a id="the-redact-waterfall"></a>
+
+Every outbound record passes the `sessionTelemetry/record` waterfall immediately after projection. This package ships no rules: with no listener mounted, records reach the backend exactly as captured, so exported data is as clean as the rules a deployment mounts. Listeners stack by transforming `next()`'s return value; a throwing listener withholds that one record fail-closed. Redaction applies to the outbound copy only — the canonical session log is never rewritten.

+
+This section explains the capture design; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The seam is built on one boundary: the harness's aspect ends at `emit()`. Capture, projection, redaction, and the handoff cursor live here; batching, retry, queueing, and loss policy are the reporting SDK's, deliberately not modelled or wrapped. The design and rejected alternatives are pinned in the [revival Agent Note](../../../.agents/notes/implemented/feature/2026-07-23-session-telemetry-otel-revival.md).
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Service Definition: `SessionTelemetryBackend`/`SessionTelemetrySink` contract, record vocabulary, `session-telemetry/record` waterfall declaration |
+| [`src/coordinator.ts`](src/coordinator.ts) | Capture: live listeners, on-demand replay, chunk projection, redaction, handoff cursor, containment |
+
+### Capture flow
+
+Live capture registers, through the composing fiber's effects: `session/created` adopts the session and replays its log from the handoff cursor; `session/event` projects, deep-copies, redacts, and hands off with zero I/O; `session/flush` forwards the optional hint and returns void so the loop's awaited parallel never waits on telemetry; `session/disposed` captures the session's `shutdown` marker and retires it; `agent/error` is the one live-bus relay, because the session-event vocabulary intentionally has no operational-error record. Disposal captures shutdown markers for still-live sessions, then awaits the backend's `shutdown()`. On-demand capture registers only the disposal effect and reads the canonical log on request. Every synchronous handler runs inside containment so a failing backend or rule can never starve other listeners or reach the agent loop.
+
+### The handoff cursor
+
+A module-scope `WeakMap<Session, seq>` records, per session, the highest seq handed off (not delivered). Live capture advances it at append time; on-demand capture advances it only while handing a requested prefix. An uncaptured prefix remains solely in the canonical log, so a coordinator reload adds no telemetry-owned recovery state; a missing cursor safely degrades to re-handing from the session's construction boundary, absorbed by receiver-side dedupe on `(session.id, event.seq)`. This is a narrow, documented exception to the registrations-are-effects discipline: entries die with their sessions, the value is a monotonic watermark, and losing it is never an error. The accepted cost matches at-most-once delivery: a resumed session does not backfill records a previous process failed to deliver.

 ## Known Limitations and Deferred Work
 
-- **Best-effort delivery** — the cursor marks handed-off, not delivered; a session torn down inside a reload window cannot be re-adopted; whatever sits in a backend queue at crash time is lost. A durable outbox (spool, per-sink cursors, at-least-once) is deferred until a deployment states a crash-loss requirement — see [the revival Agent Note](../../../.agents/notes/implemented/feature/2026-07-23-session-telemetry-otel-revival.md).

+
+

 [English](README.md) | 中文
 
-遥测（telemetry）Service Definition 声明 `SessionTelemetrySink` 后端约定，捕获协调器把会话记录传给实现该约定的任意上报 SDK 后端。捕获侧可跟随实时会话事件，也可按需回放权威会话日志前缀。本包调用 `emit()` 后就停止处理：批处理、重试、排队与丢失策略都属于后端自身的 SDK，本包既不规定也不包装。设计依据与被否决的替代方案见[复活 Agent Note](../../../.agents/notes/implemented/feature/2026-07-23-session-telemetry-otel-revival.zh.md)、[反馈门控投递](../../../.agents/notes/implemented/feature/2026-08-05-feedback-gated-session-telemetry.zh.md)与[无缓冲反馈回放](../../../.agents/notes/implemented/simplification/2026-08-06-buffer-free-feedback-telemetry.zh.md)。
+## 概述
 
-## 后端约定
+`dsh-session-telemetry` 捕获会话活动用于对外上报：它把会话事件投影为遥测记录，允许部署方脱敏，再交给实现其约定的上报后端。部署方不直接加载本包——它们只加载一个后端（随附的 OpenTelemetry 后端是 `dsh-session-telemetry-otel`），由它注册 `ctx.sessionTelemetry` 并组装捕获协调器。seam 拥有捕获、脱敏与共享披露；批处理、重试、排队与丢失策略属于后端自身的 SDK，止于 `emit()`。每个已挂载后端都披露其部署级共享策略，使确认 surface 能够报告会话是否以及如何被共享。约定与捕获行为在前；实现内部细节放在下方可折叠的开发者章节中。
 
-`SessionTelemetrySink` 有三个成员：`emit(record)` 必须入队且不能阻塞，因为它会在 `session/event` 或显式权威日志回放期间同步执行；可选的 `flush()` 是轮次结束后的提示，调用方不等待结果，多数后端省略它并使用 SDK 的常规批处理计划；`shutdown()` 排空已入队记录，并在 SDK 停止后结束，dispose（资源释放）会等待它。提供 `flush()` 的实现必须安排并发 flush 与 `shutdown()` 最终排空的先后顺序。`SessionTelemetryBackend` 将此 API 注册在 `sessionTelemetry` 上下文键下：每个上下文只允许一个实现，重复加载会抛出异常。后端以 `live` 或 `on-demand` 捕获构造 `SessionTelemetryCoordinator`，并在自己选择的触发器中调用 `captureSession(session, throughSeq?)`。
+## 目录
 
-该服务还携带必需的 [`SessionTelemetrySharingStatus`](#the-sharing-disclosure) `sharing` 成员：每个后端都必须向面向用户的确认 surface（`/feedback` 命令的确认文本）披露的部署级共享策略。消费方只有在未挂载任何遥测服务时才渲染「未配置」。seam 拥有该词汇（`full` | `feedback-only` | `disabled`），因此任何后端都可以披露策略，而无需依赖 OTel 包。

+## 使用本包
+
+作为部署方，选择一个后端并挂载它，当记录不能以捕获原样离开进程时添加脱敏规则。作为后端作者，实现三成员约定，并以一种捕获模式组装协调器。
+
+### 选择并挂载后端
+
+只加载一个后端插件；它把捕获协调器与自己的投递流水线注册为 `ctx.sessionTelemetry`，重复加载会抛出异常。已挂载后端通过必需的 [`sharing` 成员](#the-sharing-disclosure) 披露共享策略，`/feedback` 的确认文本会渲染它；只有在未挂载任何遥测服务时，消费方才渲染「未配置」。
+
+### 后端约定
+
+后端实现三个成员：`emit(record)` 必须是非阻塞入队，因为它会在会话事件路径上同步执行；可选的 `flush()` 是轮次结束后的即发即忘提示，多数后端为了遵循 SDK 自身的批处理计划而省略它；`shutdown()` 排空已入队记录，并在 SDK 停止后结束，dispose（资源释放）会等待它。实现 `flush()` 的后端必须安排并发 flush 与最终 `shutdown()` 排空的先后顺序。
+
+### 捕获内容
+
+捕获以两种模式之一运行。`live` 捕获在追加时跟随会话事件、在挂载时回放已存活会话并记录生命周期标记；`on-demand` 捕获只在后端通过 `captureSession(session, throughSeq?)` 请求前缀时读取权威会话日志。ledger 记录与会话事件一一对应，唯有一个投影例外：每个 `(turn, step)` 只发出第一条 `assistant/chunk`，因此导出流中的 `seq` 缺口是常态，绝不是丢失信号。每条记录携带事件的完整数据、最小身份属性与预先映射的严重级别（`tool/result.isError`、`turn/end` 的错误原因与 `agent-error` 映射为 `error`；其余为 `info`）。
+
+### 共享披露
 
 <a id="the-sharing-disclosure"></a>
 
-## 共享披露
+每个后端都通过 seam 的 `sharing` 词汇披露其部署级共享策略：`full`（每个事件在发生时立即交接）、`feedback-only`（在 `feedback/record` 事件释放其之前的未释放前缀之前，不交接任何内容）或 `disabled`（完全不交接任何内容）。已记录反馈条目的确认文本会报告该状态；披露从不声称投递——交接是非阻塞入队，批处理、重试与丢失策略仍归后端 SDK。
 
-一条已记录的反馈条目的确认文本会报告该会话是否以及如何被共享，读取自已挂载后端的 `sharing`。后端根据其部署配置设置该属性：`full`（每个事件在发生时立即交接）、`feedback-only`（在 `feedback/record` 事件释放其之前的未释放前缀之前，不交接任何内容）或 `disabled`（完全不交接任何内容）。消费方把状态映射为面向用户的文案；披露从不声称投递——交接是非阻塞入队，批处理、重试与丢失策略仍归后端 SDK。
-
-## 捕获点
-
-在 `live` 模式中，协调器的全部注册都经由组合方 fiber 的 effect 完成：`session/created`（收养：记录 header，并经投影从构造边界起回读日志；来自 fork 或恢复的构造函数种子绝不会在 firehose 上再次发出，也绝不会再次导出）、`session/event`（投影、深拷贝、脱敏，再交接；零 I/O）、`session/flush`（转发可选的 `flush()` 提示并返回 void；循环所等待的并行任务绝不能等待遥测）、`session/disposed`（在会话自身的终止边缘捕获该会话的 `shutdown` 运维记录，然后将其退役）、`agent/error`（唯一的实时总线转发；会话事件词汇有意不包含运维错误记录）、一个 dispose effect（捕获每个仍存活会话的 shutdown，再等待后端的 `shutdown()`；失败只发出警告而不抛出），以及对 `ctx.sessions.list()` 的收养扫描（热重载不会重放 `session/created`）。在 `on-demand` 模式中，协调器只注册 dispose effect：`captureSession()` 读取权威日志，直至可选的序列号边界（含边界）；flush 提示与运维事件留在本地。

-每个 `(turn, step)` 只发出第一条 `assistant/chunk`；其余分片在捕获时丢弃，且绝不推进游标。这一条分片就是「流已开始」的信号：`step/start`、首分片是否存在、`assistant/message` 是否存在，加上 `turn/end` 的原因，无需分片流量即可区分「请求从未开始」与「流中途夭折」，首个 token 延迟（time-to-first-token）也仍然可以计算。分片省略使导出流中的 `seq` 缺口成为常态：缺口绝不是丢失信号。其余所有事件类型都会完整透传，包括本包从未听说过的插件所合并的事件类型。
+### 设计理念
 
-## 逻辑记录
+seam 建立在一个边界之上：harness 的职责止于 `emit()`。捕获、投影、脱敏与 handoff 游标都在这里；批处理、重试、排队与丢失策略属于上报 SDK，本包有意不建模也不包装。设计与被否决的替代方案见[复活 Agent Note](../../../.agents/notes/implemented/feature/2026-07-23-session-telemetry-otel-revival.zh.md)。
 
-`SessionTelemetryRecord` 包含：`channel`（`ledger` | `ops`）、`time`（epoch 毫秒）、`severity`（预先映射好的严重级别：`tool/result.isError`、`turn/end` 的错误原因与 `agent-error` 映射为 ERROR，其他已捕获记录映射为 INFO，而 `sessionTelemetry/record` 策略可以指定 WARN）、只含身份信息的 `attributes`（`session.id`、`event.type`、`event.seq`，header 中存在时再加 `session.cwd`/`session.parent_id`/`session.seed_length`），以及作为 `body` 的完整深拷贝 `event.data`，且以脱敏后的内容为准。运维记录携带 `sessionTelemetry.op`（`agent-error` | `shutdown`）和 `session.id`，并刻意不带 `event.seq`/`event.type`：它们是用来告警的信号，不是用来累加的条目；`agent-error` 会把任意抛出值规范化为稳定的 `{ name, message }` 记录主体。交接之后的投递由后端 SDK 负责；重复仍然可能出现（无游标的重新收养、SDK 重试），因此接收端基于 `(session.id, event.seq)` 去重。
+### 源码地图
 
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Service Definition：`SessionTelemetryBackend`/`SessionTelemetrySink` 约定、记录词汇、`session-telemetry/record` waterfall 声明 |
+| [`src/coordinator.ts`](src/coordinator.ts) | 捕获：live 监听器、on-demand 回放、分片投影、脱敏、handoff 游标、异常隔离 |
+
+### 捕获流程
+
+live 捕获通过组合方 fiber 的 effect 注册：`session/created` 收养会话并从 handoff 游标起回放其日志；`session/event` 投影、深拷贝、脱敏并交接，零 I/O；`session/flush` 转发可选的提示并返回 void，使循环所等待的并行任务绝不等待遥测；`session/disposed` 捕获会话的 `shutdown` 标记并退役它；`agent/error` 是唯一的实时总线转发，因为会话事件词汇有意不包含运维错误记录。dispose 会为仍存活的会话捕获 shutdown 标记，然后等待后端的 `shutdown()`。on-demand 捕获只注册 dispose effect，并在请求时读取权威日志。每个同步处理器都运行在异常隔离之内，使失败的后端或规则永远不会饿死其他监听器，也永远不会触及 agent loop。
+
+### handoff 游标
+
+一个模块作用域的 `WeakMap<Session, seq>` 按会话记录已交接（而非已投递）的最高 seq。live 捕获在追加时推进它；on-demand 捕获只在交接所请求的前缀时推进它。未捕获的前缀只留在权威日志中，因此协调器重载不会增加遥测自有的恢复状态；游标缺失时安全退化为从会话构造边界起重新交接，由接收端基于 `(session.id, event.seq)` 的去重吸收。这是对「注册即 effect」纪律的一次有意的、有文档说明的窄例外：条目随其会话消亡，值是单调水位线，丢失它绝不是错误。由此接受的代价与至多一次（at-most-once）投递一致：恢复的会话不会回填上一个进程未能投递的记录。

+## Use this package
+
+Mount this plugin beside the title service when a session should be retitled as it grows, so the title keeps representing the whole conversation. It requires the full [shared LLM configuration](../session-title-llm/README.md#configuration) with no defaults.
+
+### When titles are generated
+
+A new revision starts after each new eligible human prompt, including prompts in child sessions; the generation folds all eligible messages through the current revision, seeded history included. A newer revision aborts and supersedes older work, so a stale completion can never commit. An automatic failure — including input over `maxInputBytes`, which fails instead of truncating history — warns and keeps the prior title; `ctx.sessionTitle.refresh()` is the explicit retry.
+
+### Configuration
+
+The plugin accepts the complete required [shared LLM configuration](../session-title-llm/README.md#configuration): `targetWords`, `targetCjkCharacters`, `maxInputBytes`, `maxOutputTokens`, `timeoutMs`, and the optional paired `provider`/`model` route. Omit both to inherit the exact route from each current logged main request, or set both to route title generation independently. The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-session-title-all-prompts-llm) is the exhaustive source for every accepted field.
+
+### Failures and recovery
+
+If the final framed aggregate prompt exceeds `maxInputBytes`, the request fails instead of truncating history; automatic use warns and keeps the prior title, and only an explicit `refresh()` retries. Automatic work adds no tokens and no latency to the main agent request.

+
+### Design concept
+
+A thin provider plugin: it registers the `all-prompts` cadence with an identity selector over all eligible messages, and delegates everything else to the [shared LLM policy](../session-title-llm/README.md).
+
+### Source map

+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: shared config schema, provider registration with the all-messages selector |
+
+### Scheduling
+
+The title service schedules automatic work: for the `all-prompts` cadence, every new eligible user message starts a revision, and a newer revision supersedes older work; the provider call begins after the exact main-request route is logged.

+
+当会话应随其增长而重新生成标题、使标题持续代表整个对话时，在标题服务旁挂载此插件。它要求完整的[共享 LLM 配置](../session-title-llm/README.zh.md#configuration)，且无默认值。
+
+### 标题生成时机
+
+每条新的符合条件用户提示词之后都会启动新修订，包括子会话中的提示词；生成会折叠截至当前修订的所有符合条件消息，预置历史也包含在内。较新的修订会中止并取代旧工作，因此陈旧的完成结果永远无法提交。自动失败——包括输入超过 `maxInputBytes`（此时请求失败而非截断历史）——会发出警告并保留先前标题；`ctx.sessionTitle.refresh()` 是显式重试。
+
+### 配置
+
+插件接受完整必填的[共享 LLM 配置](../session-title-llm/README.zh.md#configuration)：`targetWords`、`targetCjkCharacters`、`maxInputBytes`、`maxOutputTokens`、`timeoutMs`，以及可选成对的 `provider`/`model` 路由。同时省略二者，会继承每个当前已记录主请求的确切路由；同时设置二者，则让标题生成使用独立路由。生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-session-title-all-prompts-llm)是每个受支持字段的穷尽式真源。
+
+### 失败与恢复
+
+如果最终封装的聚合提示词超过 `maxInputBytes`，请求会失败而不是截断历史；自动使用时会发出警告并保留先前标题，只有显式 `refresh()` 会重试。自动工作不会为主 agent 请求增加 token 或延迟。

An automatic failure retains the fallback and is retried only through `ctx.sessionTitle.refresh()`. It uses the complete required shared LLM configuration from `dsh-session-title-llm`, so route, prompt, budget, and cancellation behavior cannot drift. Automatic behavior and configuration come first; the implementation is a thin registration over the shared policy.

+## Use this package
+
+Mount this plugin beside the title service when a session should be titled from its first eligible human message. It requires the full [shared LLM configuration](../session-title-llm/README.md#configuration) with no defaults.
+
+### When titles are generated
+
+Automatic generation runs only for a fresh session with no parent and no prior title: after its first eligible human message, the fallback is created and one auxiliary request summarizes that message. Later prompts, explicit user renames, and inherited fork history do not trigger another automatic call. An automatic failure keeps the fallback; `ctx.sessionTitle.refresh()` is the explicit retry. Forks keep their inherited title and never run this provider automatically, even when their seeded first message came from the parent.
+
+### Configuration
+
+The plugin accepts the complete required [shared LLM configuration](../session-title-llm/README.md#configuration): `targetWords`, `targetCjkCharacters`, `maxInputBytes`, `maxOutputTokens`, `timeoutMs`, and the optional paired `provider`/`model` route. Omit both to inherit the exact route from the current logged main request, or set both to route title generation independently. The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-session-title-first-prompt-llm) is the exhaustive source for every accepted field.
+
+### Failures and recovery
+
+A generation that fails — a missing route before any main request, input over `maxInputBytes`, timeout, cancellation, or invalid model output — warns and keeps the current title; only an explicit `refresh()` retries. Automatic work adds no tokens and no latency to the main agent request.

+
+当会话应从第一条符合条件用户消息生成标题时，在标题服务旁挂载此插件。它要求完整的[共享 LLM 配置](../session-title-llm/README.zh.md#configuration)，且无默认值。
+
+### 标题生成时机
+
+自动生成只对无父会话、也无先前标题的全新会话运行：在其第一条符合条件用户消息之后，创建回退并发出一次辅助请求来总结该消息。后续提示词、显式用户重命名与继承的 fork 历史都不会触发再次自动调用。自动失败会保留回退；`ctx.sessionTitle.refresh()` 是显式重试。fork 会保留继承的标题，绝不会自动运行此提供方，即使其预置的首消息来自父会话。
+
+### 配置
+
+插件接受完整必填的[共享 LLM 配置](../session-title-llm/README.zh.md#configuration)：`targetWords`、`targetCjkCharacters`、`maxInputBytes`、`maxOutputTokens`、`timeoutMs`，以及可选成对的 `provider`/`model` 路由。同时省略二者，会继承当前已记录主请求的确切路由；同时设置二者，则让标题生成使用独立路由。生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-session-title-first-prompt-llm)是每个受支持字段的穷尽式真源。
+
+### 失败与恢复
+
+失败的生成——主请求之前缺少路由、输入超过 `maxInputBytes`、超时、取消或无效模型输出——会发出警告并保留当前标题；只有显式 `refresh()` 会重试。自动工作不会为主 agent 请求增加 token 或延迟。

-Shared implementation policy for model-backed session-title providers. It resolves the auxiliary route, frames exact selected human messages as JSON, records the exact dispatchable request, applies a language-aware title instruction, enforces input and output budgets, composes timeout and caller cancellation, assembles the stream, and returns normalized text with exact source seqs plus the provider/model route used to generate it.
+## Summary
 
-This package is a library, not a Cordis plugin. The provider plugins call `registerSessionTitleLlmProvider()` with their cadence and message selector; it validates shared config and delegates each revision to `generateSessionTitleWithLlm()`, so registration, route, prompt, cancellation, and validation behavior cannot drift between them.
+`dsh-session-title-llm` runs model-backed title generation through one shared policy: it resolves the auxiliary route, frames the exact selected human messages as JSON, enforces input and output budgets, composes timeout and caller cancellation, and validates the model's output before a title is accepted. It is a library, not a Cordis plugin — the shipped provider plugins call `registerSessionTitleLlmProvider()` with their cadence and message selector, and the helper validates shared config and delegates every revision to one generation path, so registration, route, prompt, cancellation, and validation behavior cannot drift between them. Deployments configure it through the provider plugins, which require every limit. The route, failure, and configuration contracts come first; the request internals live in a collapsible developer section below.
 
-## Route and failure contract
+## Table of Contents
 
-`provider` and `model` overrides are optional but must be supplied together as non-empty strings. Without that pair, the helper uses the exact provider/model route captured from the current session's logged `request/header`; an explicit refresh before any route exists therefore needs overrides. The helper measures the final JSON-framed user prompt, including seq fields, wrappers, and JSON escaping, against `maxInputBytes` before logging or dispatch instead of truncating it. Timeout and caller cancellation are rechecked while consuming the stream and after it completes, so a late successful result cannot be accepted even if an interceptor or adapter ignores abort. Malformed or empty output, tool calls, and non-stop finish reasons also reject; the session-title service decides whether that rejection is an automatic warning or an explicit caller failure.

+- [Dev Note](#dev-note)
 
-After route and input validation, the helper records the exact dispatchable request as a log-only `session/title-llm-request` event before model dispatch. The event stays outside derived model history and remains recorded if the model call later fails; validation failures create no event. The request purpose disables thinking for DeepSeek title calls, while other adapters own their purpose-specific behavior.
+-----
 
-## Configuration
+<a id="use-this-package"></a>
+## Use this package
+
+As a deployment, configure this policy through the [first-prompt](../session-title-first-prompt-llm/README.md) or [all-prompts](../session-title-all-prompts-llm/README.md) provider plugin. As a provider author, register through the shared helper instead of hand-rolling generation.
+
+### Registering a provider
+
+A provider plugin calls `registerSessionTitleLlmProvider(ctx, config, id, automatic, selectMessages)`; the helper validates the shared config, registers the provider on `ctx.sessionTitle`, and runs every generation through the shared policy. The two shipped plugins register the `first-prompt` and `all-prompts` cadences with their message selectors, and a second registration on the service throws.
+
+### Route and failure contract
+
+`provider` and `model` overrides are optional but must be supplied together as non-empty strings. Without that pair, the helper uses the exact provider/model route captured from the current session's logged `request/header`, so an explicit refresh before any route exists needs overrides.

+A generation validates the config once at registration; each revision frames the selected messages as JSON, measures the framed prompt's UTF-8 bytes against `maxInputBytes`, resolves the route (the explicit pair or the logged `request/header`), appends a log-only `session/title-llm-request` event carrying the exact dispatchable request, then streams through `ctx.llm` under a composed timeout and cancellation deadline. The dispatched envelope carries `purpose: 'session-title'` and deliberately lacks the agent loop's process-local request identity; the DeepSeek adapter maps that purpose to thinking-disabled so the small output budget is reserved for visible title text, and other adapters own their purpose-specific behavior. Output assembles into text blocks only; tool calls, malformed or empty output, and non-stop finish reasons reject, and a later model failure leaves the request record intact.

-由模型支持的会话标题提供方的共享实现策略。它解析辅助路由，将精确选中的用户消息封装为 JSON，记录可分发的确切请求，应用语言感知的标题指令，强制执行输入和输出预算，组合超时与调用方取消，组装流，并返回规范化文本，同时给出确切来源 seq 以及生成该文本时使用的提供方／模型路由。
+## 概述
 
-此包是普通库，不是 Cordis 插件。提供方插件调用 `registerSessionTitleLlmProvider()`，传入各自节奏与消息选择器；该函数验证共享配置，并将每次修订委派给 `generateSessionTitleWithLlm()`，使各插件的注册、路由、提示词、取消与验证行为不会漂移。
+`dsh-session-title-llm` 让模型支持的标题生成都经过同一份共享策略：它解析辅助路由，把精确选中的用户消息封装为 JSON，强制执行输入与输出预算，组合超时与调用方取消，并在标题被接受前校验模型输出。它是普通库而非 Cordis 插件——随附提供方插件以各自的节奏与消息选择器调用 `registerSessionTitleLlmProvider()`，该辅助函数验证共享配置并把每次修订委托给同一条生成路径，因此注册、路由、提示词、取消与校验行为不会在它们之间漂移。部署方通过要求所有上限的提供方插件来配置它。路由、失败与配置约定在前；请求内部细节放在下方可折叠的开发者章节中。
 
-## 路由与失败约定
+## 目录
 
-`provider` 和 `model` 覆盖项都是可选的，但必须同时作为非空字符串提供。如果没有这一对取值，辅助模块会使用当前会话已记录 `request/header` 中捕获的确切提供方／模型路由；因此，在任何路由出现前显式刷新时必须提供覆盖项。辅助模块在记录或分发前，依据 `maxInputBytes` 检查最终 JSON 封装用户提示词的大小，包括 seq 字段、包装层与 JSON 转义，而不是将其截断。消费流期间和流完成后都会重新检查超时与调用方取消，因此即使拦截器或适配器忽略 abort，也不能接受迟到的成功结果。格式错误或空输出、工具调用和非 stop 结束原因同样会导致调用被拒绝；会话标题服务决定该拒绝属于自动警告还是显式调用方失败。

-路由与输入校验完成后，辅助模块会在模型分发前将确切的可分发请求记录为仅写入日志的 `session/title-llm-request` 事件。该事件不进入派生模型历史；后续模型调用失败时仍会保留，而校验失败不会创建事件。请求用途会使 DeepSeek 标题调用禁用思考，其他适配器则负责自身的用途专用行为。

+### 请求流程
+
+生成在注册时校验一次配置；每次修订把选中的消息封装为 JSON，依据 `maxInputBytes` 检查封装提示词的 UTF-8 字节数，解析路由（显式对或已记录 `request/header`），追加一条携带确切可分发请求的仅日志 `session/title-llm-request` 事件，然后在组合的超时与取消截止时间内通过 `ctx.llm` 流式生成。分发的封套携带 `purpose: 'session-title'`，且有意不包含 agent loop 的进程本地请求身份；DeepSeek 适配器根据该用途禁用思考，使少量输出预算全部用于可见标题文本，其他适配器负责自身用途专用行为。输出只组装为文本块；工具调用、格式错误或空输出与非 stop 结束原因都会拒绝，后续模型失败会保留请求记录。

 ### 辅助标题请求
 
-#### 模型看到的内容
+#### 模型看到什么
 
 标题模型会收到固定系统指令，要求以输入语言返回一个简洁且无装饰的标题；该指令包含所配置的词数与 CJK 字符数目标。它唯一的用户消息包含一个 JSON 数组，其中是精确选中的用户消息及其 seq。
 
 #### Token 影响
 
-辅助请求根据所选输入大小和 `maxOutputTokens` 消耗 token。它与主 agent（智能体）请求相互独立，不会向 agent 历史增加标题文本或封装内容。DeepSeek 标题调用会关闭思考；主对话保留自身配置的思考模式。

-Log-backed session titles with an immediate deterministic fallback and one optional asynchronous provider. Every accepted revision is a log-only `session/title` event; `foldSessionTitle()` and `ctx.sessionTitle.get()` select the latest event and return its event seq and timestamp.
+## Summary
 
-Only text blocks from human `user/message` events are eligible. The first eligible prompt schedules a fallback from its first words within the configured UTF-8 byte limit. Whitespace is normalized, terminal control sequences are removed, and truncation never splits a code point. Empty and non-text prompts wait for later eligible input.
+`dsh-session-title` gives every session a title clients can display: a deterministic fallback from the first eligible human message, an optional asynchronous provider (such as a model-backed one), or an explicit user rename. Every accepted revision is a log-only `session/title` event, so titles survive replay, resume, and paging exactly like any other session event and never enter the model surface. The service owns scheduling and acceptance; the optional provider owns generation. Automatic work never delays the main agent response, and a newer revision supersedes older work. Configuration and title sources come first; the implementation internals live in a collapsible developer section below.
 
-## Service: `SessionTitleService` (ctx key: `sessionTitle`)
+## Table of Contents
 
-- `get(session)` folds the latest accepted title from a live or replayed log.
-- `refresh(session, signal?)` materializes the fallback when needed, then explicitly runs the registered provider over the current eligible messages. Provider errors and caller cancellation reject; cancellation does not roll back an already accepted fallback event.
-- `rename(session, title)` accepts an explicit user title synchronously: it normalizes the text, supersedes in-flight automatic work, and appends a `session/title` event with the `user` source. A user-sourced latest title pins the session — later user messages schedule no automatic revision; an explicit `refresh` remains the deliberate unpin.
-- `register(provider)` installs the sole optional provider and returns its awaitable Cordis effect disposer. A second registration throws immediately; disposal aborts pending and active calls, waits for their settlement, and only then permits another provider to register.

-Automatic work never delays the main agent response. A provider starts only after a marked loop-built request's exact route matches the current logged `request/header`, including when the unchanged header needs no new snapshot. Its late completion appends a standalone log-only event directly through `Session` without opening a turn. Persistence observes that event eagerly and drains on ordinary lifecycle checkpoints; title publication itself does not force a flush. Automatic failures warn and retain the latest title. New all-message revisions, provider disposal, session disposal, and explicit refresh abort older work, and a stale completion cannot append. Concurrent explicit refreshes reserve their revision before provider work, while overlapping automatic and explicit fallback requests share one session-local in-flight append. The service and bundled model provider each append their own literal event type, so no generic title-write marker, cast, or settlement queue is needed. Service teardown cancels queued work and drains calls that ignore cancellation before unloading completes.
+-----
 
-Forks inherit title events in their seed unchanged. The first-prompt cadence does not automatically retitle a child; the all-messages cadence may append a new revision after the child receives a later human prompt.
+<a id="use-this-package"></a>
+## Use this package
 
-## Configuration
+Mount the service to give sessions titles that clients can display and that never reach the model. The common path is explicit: load the session store, mount the service with its required limits, and optionally mount one provider plugin.
 
-All limits are required; the library supplies no defaults.
+### Choosing a title source
 
-| Key | Contract |
+Titles come from three sources, newest wins. The built-in fallback derives from the first eligible human message's leading words within the configured caps; a registered provider generates a title over eligible messages; an explicit `rename()` accepts a user-supplied title. Only text blocks from human `user/message` events are eligible, and empty or non-text prompts wait for later eligible input. A user-sourced latest title pins the session — later user messages schedule no automatic revision, and an explicit `refresh()` remains the deliberate unpin.
+
+### Minimal configuration
+
+All limits are required; the library supplies no defaults. Mount the service with the three bounds:
+
+```yaml
+- name: '@deepseek-ai/dsh-session'
+- name: '@deepseek-ai/dsh-session-title'
+  config:
+    fallbackMaxWords: 8
+    fallbackMaxBytes: 96
+    maxTitleBytes: 120
+```
+
+| Field | Default | Meaning |
+|---|---|---|
+| `fallbackMaxWords` | required | Maximum whitespace-delimited words in the deterministic fallback |
+| `fallbackMaxBytes` | required | Maximum UTF-8 bytes in the fallback; must not exceed `maxTitleBytes` |
+| `maxTitleBytes` | required | Maximum UTF-8 bytes accepted from any source |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-session-title) is the exhaustive source for every accepted field and its JSDoc.
+
+### Adding a provider
+
+One optional asynchronous provider may be registered through `ctx.sessionTitle.register(provider)`; a second registration throws. The shipped model-backed providers are [first-prompt](../session-title-first-prompt-llm/README.md) and [all-prompts](../session-title-all-prompts-llm/README.md), both using the shared [LLM generation policy](../session-title-llm/README.md). A provider starts only after a marked loop-built request's exact route matches the logged `request/header`, and a newer revision supersedes and aborts older work.
+
+### Reading titles
+
+`get(session)` folds the latest accepted title from the live or replayed log, and `foldSessionTitle(events)` is the pure fold over a log. The service also registers a `title` projection unit — the plain title string — for client list rows when a projection registry is composed. An explicit `refresh(session)` materializes the fallback when needed, then explicitly runs the registered provider over the current eligible messages.
+
+### Failures and recovery
+
+Automatic failures warn and retain the latest title; explicit `refresh()` rejects on provider error or caller cancellation, and cancellation does not roll back an already accepted fallback event. Automatic work never delays the main agent response, its late completion appends a standalone log-only event without opening a turn, and a stale completion cannot append. Forks inherit title events in their seed unchanged.

+
+This section explains the title design; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+Titles are durable, log-only state: every accepted revision is a `session/title` event, and `foldSessionTitle()` selects the latest, so a title survives replay, resume, and paging exactly like any other session event. The service owns scheduling, supersession, and acceptance; providers own generation.
+
+### Source map
+
+| File | Role |
 |---|---|
-| `fallbackMaxWords` | Positive maximum whitespace-delimited words in the deterministic fallback. |
-| `fallbackMaxBytes` | Positive maximum UTF-8 bytes in the fallback; must not exceed `maxTitleBytes`. |
-| `maxTitleBytes` | Positive maximum UTF-8 bytes accepted from any source. |
+| [`src/index.ts`](src/index.ts) | Service: config, fold, fallback scheduling, provider registry, concurrency, `title` projection unit |
+| [`src/normalize.ts`](src/normalize.ts) | Title-text cleaning, UTF-8-safe truncation, and the deterministic fallback |
+| [`src/types.ts`](src/types.ts) | One home of the `title` projection-key declaration |
 
-## Provider contract
+### Lifecycle and concurrency
 
-A provider supplies a branded stable id, automatic mode (`first-prompt` or `all-prompts`), and `generate(request)`. The request carries the live session, all eligible messages through one fixed revision, the current logged main-request route when available, and cancellation. The result identifies a non-empty title, unique ordered source-message seqs from that request, and the optional provider/model route used to generate it. The service normalizes and validates the result before it becomes durable.
+Per-session work state tracks a revision counter, an in-flight fallback, and pending and active provider work. A newer user message, provider disposal, session disposal, or explicit refresh aborts older work through an `AbortController`; a completion whose provider, revision, session, or signal is stale cannot append. Explicit refreshes reserve their revision before provider work; overlapping automatic and explicit fallback requests share one session-local in-flight append. Service teardown cancels queued work and drains calls that ignore cancellation before unloading completes.
 
-See the [session-title data structures](../../../docs/subsystems/session-title.md) and [implemented decision](../../../.agents/notes/implemented/feature/2026-07-21-log-backed-session-titles.md).
+### Normalization
 
+Accepted titles are cleaned of terminal control sequences, directional and invisible controls, and non-whitespace C0/C1 controls; whitespace is normalized, and truncation to the byte caps never splits a Unicode code point. The deterministic fallback takes the first eligible message's leading words within `fallbackMaxWords` and `fallbackMaxBytes`.

-由日志支持的会话标题，提供即时确定性回退与一个可选异步提供方。每次已接受的修订都是仅写入日志的 `session/title` 事件；`foldSessionTitle()` 与 `ctx.sessionTitle.get()` 会选择最新事件，并返回其事件 seq 和时间戳。
+## 概述
 
-只有用户 `user/message` 事件中的文本块符合条件。第一条符合条件的提示词会安排回退，从其开头若干词生成标题，并受所配置 UTF-8 字节上限约束。系统会规范化空白、移除终端控制序列，且截断绝不会切断码点。空提示词和非文本提示词会等待后续符合条件的输入。
+`dsh-session-title` 为每个会话提供客户端可以显示的标题：来自第一条符合条件用户消息的确定性回退、一个可选异步提供方（例如模型支持的提供方），或显式用户重命名。每个已接受的修订都是仅写入日志的 `session/title` 事件，因此标题像任何其他会话事件一样在回放、恢复与分页中存活，且绝不进入模型可见面。服务拥有调度与接受；可选提供方负责生成。自动工作绝不会延迟主 agent 响应，较新的修订会取代旧工作。配置与标题来源在前；实现内部细节放在下方可折叠的开发者章节中。
 
-## 服务：`SessionTitleService`（ctx 键：`sessionTitle`）
+## 目录
 
-- `get(session)` 从活跃或回放日志折叠最新已接受标题。
-- `refresh(session, signal?)` 在需要时物化回退，然后显式运行已注册提供方，处理当前符合条件的消息。提供方错误或调用方取消都会导致返回的 Promise 被拒绝；取消不会回滚已接受的回退事件。
-- `rename(session, title)` 同步接受用户显式标题：规范化文本、取代在途自动工作，并追加一条 `user` 来源的 `session/title` 事件。用户来源的最新标题会钉住该会话——后续用户消息不再安排自动修订；显式 `refresh` 仍是有意的解钉手段。
-- `register(provider)` 安装唯一可选提供方，并返回可等待的 Cordis effect disposer。第二次注册会立即抛出；对提供方执行 dispose（资源释放）会中止待处理和活跃调用，等待其结算，之后才允许注册另一个提供方。

-自动工作绝不会延迟主 agent（智能体）响应。只有当带标记、由循环构建的请求，其确切路由与当前已记录的 `request/header` 匹配时，提供方才会启动；即使请求头未变而无需新快照，也适用此规则。延迟完成会直接通过 `Session` 追加一个独立的纯日志事件，而不打开轮次。持久化会立即观察到该事件，并在常规生命周期检查点完成刷写；标题发布本身不会强制刷写。自动失败会发出警告并保留最新标题。新的全消息修订、提供方 dispose、会话 dispose 和显式刷新都会中止旧工作，陈旧的完成结果无法追加。并发显式刷新会在提供方工作之前预留修订号；重叠的自动／显式回退请求共享一个会话本地正在进行的追加操作。服务与内置模型提供方各自追加自己的字面事件类型，因此不需要通用标题写入标记、类型断言或结算队列。服务拆卸会取消排队工作，并在卸载完成前等待不响应取消的调用结算完成。

+## 使用本包
 
-## 配置
+挂载服务，让会话获得客户端可以显示、且绝不触及模型的标题。常用路径是显式的：加载会话存储、以必填上限挂载服务，并可选挂载一个提供方插件。
 
-所有上限都是必填项；该库不提供默认值。
+### 选择标题来源
 
-| 键 | 约定 |
+标题来自三个来源，最新者胜出。内置回退在配置上限内从第一条符合条件用户消息的开头若干词派生；已注册提供方对符合条件的消息生成标题；显式 `rename()` 接受用户提供的标题。只有人类 `user/message` 事件中的文本块符合条件，空提示词或非文本提示词会等待后续符合条件的输入。用户来源的最新标题会钉住会话——后续用户消息不再安排自动修订，显式 `refresh()` 仍是有意的解钉手段。
+
+### 最小配置
+
+所有上限都是必填项；该库不提供默认值。以三个上限挂载服务：
+
+```yaml
+- name: '@deepseek-ai/dsh-session'
+- name: '@deepseek-ai/dsh-session-title'
+  config:
+    fallbackMaxWords: 8
+    fallbackMaxBytes: 96
+    maxTitleBytes: 120
+```
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `fallbackMaxWords` | 必填 | 确定性回退中以空白分隔的最大词数 |
+| `fallbackMaxBytes` | 必填 | 回退允许的最大 UTF-8 字节数；不得超过 `maxTitleBytes` |
+| `maxTitleBytes` | 必填 | 接受任何来源标题的最大 UTF-8 字节数 |
+
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-session-title)是每个受支持字段及其 JSDoc 的穷尽式真源。
+
+### 添加提供方
+
+可选异步提供方可通过 `ctx.sessionTitle.register(provider)` 注册一个；第二次注册会立即抛出。随附的模型支持提供方是[首消息](../session-title-first-prompt-llm/README.zh.md)与[全消息](../session-title-all-prompts-llm/README.zh.md)，两者都使用共享的 [LLM 生成策略](../session-title-llm/README.zh.md)。提供方只有在带标记、由循环构建的请求的确切路由与已记录 `request/header` 匹配时才启动，较新的修订会取代并中止旧工作。
+
+### 读取标题
+
+`get(session)` 从活跃或回放日志折叠最新已接受标题，`foldSessionTitle(events)` 是对日志的纯折叠。服务还会在组合了投影注册表时注册一个 `title` 投影单元——纯标题字符串——供客户端列表行使用。显式 `refresh(session)` 在需要时物化回退，然后对当前符合条件的消息显式运行已注册提供方。
+
+### 失败与恢复
+
+自动失败会发出警告并保留最新标题；显式 `refresh()` 在提供方错误或调用方取消时拒绝，取消不会回滚已接受的回退事件。自动工作绝不会延迟主 agent 响应，其延迟完成会追加一个独立纯日志事件而不打开轮次，陈旧的完成结果无法追加。fork 出的会话会原样继承种子中的标题事件。

+# settings/ — user-editable configuration
 
 English | [中文](README.zh.md)
 
-This family resolves user-editable configuration through registered namespaces and swappable storage providers.
+## Summary
+
+The `settings/` group makes plugin configuration user-editable: a plugin registers a named namespace with a schema, and users override values in one document without touching `cordis.yml`. User overrides win over the deployment's own configuration and schema defaults, and changes apply live. Two packages cover the capability: `settings/` provides the settings service, and `settings-file/` stores every namespace in one YAML or JSON document users can edit. Settings are optional: without a provider mounted, configuration stays exactly as composed.

-File-backed settings provider. One YAML or JSON document carries every namespace section; external edits hot-publish through `ctx.settings`, and `update()` re-reads the document under a writer lock before writing back atomically, preserving the user's YAML comments, any section owned by a plugin that is not currently loaded, and any on-disk change this process has not observed yet.
+## Summary
 
-## Config
+`dsh-settings-file` keeps every namespace's user settings in one YAML or JSON document, by default `settings.yaml` under the harness home: users can edit the document directly — changes take effect live — or write through the service, which merges concurrent edits safely. YAML writes preserve comments, anchors, and formatting on every untouched node, and a section owned by a plugin that is not loaded is never dropped. Boot fails loud on an invalid document; a live reload that fails keeps the last good sections and warns rather than taking the process down.

+## Use this package
+
+Mount this provider when a composition wants one user-editable settings document. The common path is explicit: mount the provider, register namespaces through `ctx.settings`, and let users edit the document or a configuration UI write through the service.
+
+### When to choose it
+
+Choose it as the default user-settings store: one human-readable document that users can open in any editor, with changes taking effect without a restart. Choose it when comments and formatting in that document matter, because writes preserve them. A non-file store, such as a remote settings backend, is not shipped here; that would need another provider.
+
+### Minimal configuration
+
+```yaml
+- name: '@deepseek-ai/dsh-settings-file'
+  config:
+    path: /absolute/path/to/settings.yaml
+```
+
+| Field | Default | Meaning |
 |---|---|---|
-| `path` | Settings document path; extension picks the format (`.yaml`/`.yml`/`.json`) | `settings.yaml` under the harness home |
-| `dshHome` | Harness home used when `path` is omitted | `$DSH_HOME` or `~/.dsh` |
-| `watch` | Watch the document and hot-publish external edits | `true` |
-| `debounceMs` | Watcher write-settle window in milliseconds | `100` |
+| `path` | `<harness home>/settings.yaml` | Settings document path; the extension picks the format (`.yaml`, `.yml`, or `.json`) |
+| `dshHome` | `$DSH_HOME` or `~/.dsh` | Harness home used when `path` is omitted |
+| `watch` | `true` | Watch the document and hot-publish external edits |
+| `debounceMs` | `100` | Watcher write-settle window, in milliseconds |
 
-Defaulting is one explicit `resolveSpec(config)` step; an unsupported extension fails at load.
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-settings-file) is the exhaustive source for every accepted field and its JSDoc.
 
-## Behavior
+### Editing the document
 
-- **Boot fails loud, reload keeps last-good.** An existing-but-invalid document fails plugin load; once live, an unreadable or unparsable edit warns and keeps the last good sections. A missing document resolves every namespace from defaults and `base`; deleting it publishes the same empty state.
-- **Every write is a read-modify-write.** A persist first re-reads the document and publishes any difference into the seam — an external edit still inside the watcher debounce window, a change the watcher missed, or another process's write — then renders against that fresh text, so a write can never resurrect a stale document or drop an unobserved sibling section. If the on-disk document turned invalid, the write rejects loud instead of overwriting the user's manual edit.
-- **Writes hold a cross-process writer lock.** The read-render-rename cycle runs under a `wx`-created `<file>.lock` sibling with exponential backoff and a 2 s acquisition deadline. A contender times out without removing the existing lock because age cannot distinguish a crashed owner from a paused live writer; orphan recovery is an operator action. Readers never take the lock: the rename commit is atomic, so reloads are always consistent.
-- **Write-back is atomic, owner-only, and symlink-proof.** The render exclusive-creates a random-suffix temp sibling with mode `0600` (`wx` refuses to follow a planted symlink) and renames over the target, cleaning the temp up on failure.
-- **YAML edits are leaf-level diffs.** A write sets only the values that changed and deletes only the keys that were removed, so comments, anchors, and formatting survive on every untouched node and on the key of every changed pair; a changed array (or other non-map value) replaces wholesale, taking comments inside it along. JSON re-serializes without comments.
+The document is a YAML or JSON mapping of namespace to user section. Users can edit it directly: any change takes effect automatically, and deleting the file resets every namespace to defaults and `base`. A document that exists but is invalid fails plugin load at boot — the provider never silently ignores or overwrites it. Once live, an unreadable or unparsable edit warns and keeps the last good sections, so a hand-edit mistake cannot take the process down.
+
+### Writing through the service
+
+Writes through `ctx.settings` never lose concurrent changes: an external edit still in flight, a change the watcher missed, or another process's write is merged into the document before the write lands. YAML edits are leaf-level diffs: only changed values are set and only removed keys deleted, so comments, anchors, and formatting survive on every untouched node and on the key of every changed pair; a changed array or other non-map value replaces wholesale. JSON documents re-serialize without comments. If the on-disk document turned invalid, the write fails loud instead of overwriting the user's manual edit.
+
+The lock has a 2-second acquisition deadline with exponential backoff; a contender that times out leaves the existing lock in place, because lock age cannot distinguish a crashed owner from a paused live writer — orphan lock recovery is an operator action. The document is created `0600` under an owner-only `0700` directory and replaced atomically through a random-suffix temp sibling that never follows a planted symlink.
+
+### Failures and recovery
+
+- An unsupported extension fails at load — the format comes from the extension (`.yaml`, `.yml`, `.json`).
+- A missing document is an empty store; deleting the file returns to that state.
+- An invalid on-disk document at runtime blocks nothing but keeps the last good sections; a write refuses to overwrite it.
+- `prepareDocument()` materializes an absent document as an empty owner-only file before a native editor opens it.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the provider and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+- **One explicit defaulting step.** `resolveSpec(config)` resolves the filename, format, watch flag, and debounce window in one step, so programmatic construction that bypasses Schemastery normalization gets the same defaults.
+- **Boot fails loud, reload keeps last good.** An existing-but-invalid document fails plugin load; once live, an unreadable or unparsable edit warns and keeps the last good sections.
+- **Every write is a read-modify-write.** A persist first reconciles from disk and publishes any difference into the seam, then renders against that fresh text, so a write can never resurrect a stale document or drop an unobserved sibling section.
+- **Writes hold a cross-process writer lock.** The read-render-rename cycle runs under a `wx`-created `<file>.lock` sibling with exponential backoff and a 2-second acquisition deadline; readers never take the lock because the rename commit is atomic.
+- **YAML edits are leaf-level diffs.** Only changed values are set and only removed keys deleted, preserving comments, anchors, and formatting on untouched nodes.
 - **Reloads and writes share one operation chain.** Watcher refreshes and persists from every namespace queue run one at a time in queue order; each render sees the text the previous operation committed.
-- **The watcher's ready signal reconciles once.** The initial load races the watcher's own setup, so a change written in between never fires an event; the reconcile at ready closes that startup gap.
-- **The native watcher receives a canonical path.** Before Chokidar opens the target, the provider realpaths its deepest existing ancestor and restores any missing suffix. File access and user-facing diagnostics retain the configured path, while Windows cannot mix an 8.3 alias with long-form event paths inside libuv.
-- **Dispose quiesces in every watch mode.** Teardown marks the provider closed, closes the watcher when present, then waits out every queued or in-flight document operation, so nothing publishes after disposal.
-- **Self-write suppression by content.** The provider caches the last good text; a watcher event whose content equals the cache (its own write included) is a no-op.
-- **Host configuration adapters receive the resolved path.** `ctx.settings.documentPath` is the absolute `resolveSpec()` filename, including a custom YAML/JSON path; `prepareDocument()` preserves an existing file or exclusively creates an absent empty file with owner-only permissions before the Host opens it. The browser receives only an availability flag, never reconstructs `$DSH_HOME`, and never submits a filesystem target.
+- **Self-write suppression by content.** The provider caches the last good text; a watcher event whose content equals the cache — its own write included — is a no-op.
 
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Provider: spec resolution, load/parse, read-modify-write under the writer lock, watcher lifecycle, YAML/JSON rendering |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; file round-trip, watcher timing, and atomic-write behavior are proven by package tests, and the in-process commit relation is owned by `dsh-settings`) |
+
+### Document lifecycle
+
+The base service init loads and publishes the document before the service becomes injectable; the provider then starts the watcher and reconciles once at ready to close the startup gap in which a change written between the initial read and the watcher becoming active never fires an event. Every watcher event and every persist queues onto one exclusive operation chain. `reconcileFromDisk` compares on-disk text against the cache, publishes any difference (including absence as the empty document), and throws only on a parse failure so each caller picks its policy — a reload warns and keeps the last good document, a write fails loud. Disposal marks the provider closed, closes the watcher, and waits out every queued or in-flight operation so nothing publishes after teardown.
+
+### Render paths
+
+YAML renders by parsing the cached text into a mutable comment-preserving tree and patching one namespace with leaf-level edits; JSON renders by replacing one namespace key and re-serializing with two-space indentation. Before Chokidar opens the target, the provider realpaths its deepest existing ancestor and restores any missing suffix, so Windows cannot mix an 8.3 alias with long-form event paths inside libuv.

+
+### 何时选择
+
+把它当作默认的用户设置存储：一份用户可以在任意编辑器中打开的人类可读文档，变更无需重启即可生效。当文档中的注释与排版很重要时也选它，因为写入会保留它们。非文件存储（例如远程设置后端）不随本包提供；那需要另一个提供方。

-## 行为
+### 编辑文档
 
-- **启动失败并明确报错，重载保留最后可用值。** 存在但非法的文档使插件加载失败；运行中不可读或不可解析的编辑只告警并保留最后可用分节。文档缺失时所有 namespace 按默认值与 `base` 解析；删除文档发布同样的空状态。
-- **每次写入都是一次读-改-写。** persist 先重读文档并把任何差异发布进 seam——无论是仍在 watcher 防抖窗口内的外部编辑、watcher 漏掉的变更，还是另一个进程的写入——再基于这份新鲜文本渲染，因此写入绝不会复活陈旧文档，也不会丢掉未观察到的同级分节。若磁盘上的文档已变为非法，写入会明确报错并拒绝执行，而不是覆盖用户的手工编辑。
-- **写入持有跨进程写锁。** 读-渲染-rename 流程在以 `wx` 创建的同级锁文件 `<file>.lock` 保护下运行，带指数退避与 2 s 的获取期限。竞争者会超时，但不会移除现有锁，因为锁龄无法区分已经崩溃的所有者与被暂停但仍存活的写入方；遗留锁恢复须由操作者执行。读取方从不取锁：rename 提交是原子的，重载因此始终一致。

+<summary>实现细节——点击展开</summary>
+
+本节解释提供方背后的设计决策并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+- **一步显式默认化。** `resolveSpec(config)` 在一步内解析文件名、格式、watch 标志与防抖窗口，因此绕过 Schemastery 规范化的程序化构造也得到同样的默认值。
+- **启动明确报错，重载保留最后可用值。** 存在但非法的文档使插件加载失败；运行中不可读或不可解析的编辑只告警并保留最后可用分节。
+- **每次写入都是读-改-写。** persist 先从磁盘对账并把任何差异发布进 seam，再基于这份新鲜文本渲染，因此写入绝不会复活陈旧文档或丢掉未观察到的同级分节。
+- **写入持有跨进程写锁。** 读-渲染-rename 流程在以 `wx` 创建的同级 `<file>.lock` 保护下运行，带指数退避与 2 秒的获取期限；读取方从不取锁，因为 rename 提交是原子的。
+- **YAML 编辑是叶子级 diff。** 只设置变化的值、只删除被移除的键，保留未触碰节点上的注释、锚点与排版。
 - **重载与写入共享一条操作链。** watcher 刷新与来自各 namespace 队列的 persist 按队列顺序逐个执行；每次渲染都基于上一次操作提交后的文本。
-- **watcher 的 ready 信号做一次对账。** 初始加载与 watcher 自身的建立存在竞态，因此其间写入的变更绝不会触发事件；ready 时的对账补上这个启动缺口。
-- **原生 watcher 接收规范化路径。** 在 Chokidar 打开目标之前，提供方会对层级最深的现有祖先路径执行 realpath 解析，再拼回缺失的后缀。文件访问和面向用户的诊断仍使用配置路径，从而避免 Windows 在 libuv 内部混用 8.3 别名与长格式事件路径。
-- **dispose（资源释放）在每种 watch 模式下都保证完全停稳。** 卸载先把提供方标记为已关闭，在 watcher 存在时将其关闭，再等待所有已排队或进行中的文档操作完成，之后不再有任何发布。
 - **按内容抑制自写。** 提供方缓存最后可用文本；watcher 事件内容与缓存相同（含自己的写入）即为 no-op。
-- **Host 配置适配器会收到解析后的路径。** `ctx.settings.documentPath` 是 `resolveSpec()` 得出的绝对文件名，包括自定义 YAML/JSON 路径；`prepareDocument()` 会保留现有文件，或在 Host 打开文档前，以仅属主可访问的权限独占创建缺失的空文件。浏览器只收到可用性标志，绝不重建 `$DSH_HOME`，也绝不提交文件系统目标。
 
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 提供方：spec 解析、加载/解析、写锁下的读-改-写、watcher 生命周期、YAML/JSON 渲染 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；文件往返、watcher 时序与原子写入行为由包测试证明，进程内提交关系归 `dsh-settings` 所有） |
+
+### 文档生命周期
+
+基类服务 init 在服务可注入前加载并发布文档；随后提供方启动 watcher，并在 ready 时对账一次，补上「初始读取与 watcher 生效之间写入的变更永不触发事件」的启动缺口。每个 watcher 事件与每次 persist 都排上同一条独占操作链。`reconcileFromDisk` 把磁盘文本与缓存比较，发布任何差异（缺失即空文档），只在解析失败时抛出，让每个调用方自行选择策略——重载告警并保留最后可用文档，写入明确报错。卸载先把提供方标记为已关闭，关闭 watcher，再等待所有已排队或进行中的操作完成，之后不再有任何发布。
+
+### 渲染路径
+
+YAML 渲染把缓存文本解析成可变的保留注释树，再对一个 namespace 施加叶子级编辑；JSON 渲染替换一个 namespace 键后以两个空格缩进重新序列化。在 Chokidar 打开目标之前，提供方对层级最深的现有祖先路径执行 realpath 解析，再拼回缺失的后缀，从而避免 Windows 在 libuv 内部混用 8.3 别名与长格式事件路径。

-User-settings Service Definition (`ctx.settings`). One provider holds a raw document of per-namespace sections; plugins register a namespace schema and read a resolved value layered as schema defaults, then the registrant's composition `base` (its cordis.yml entry-config subset), then the user document section. Without a mounted provider nothing changes for consumers: they keep resolving entry config alone, so every composition works with or without settings.
+## Summary
 
-## Service API
+`dsh-settings` lets plugins expose configuration that users can change at runtime: a plugin registers a namespace with a schema, and the resolved value honors schema defaults, the deployment's own composition `base`, and the user-edited document section — with user overrides winning. Consumers read a snapshot of the resolved value and are notified of every committed change; configuration surfaces get one descriptor per namespace — schema, current value, which layer each field came from, effect timing — without touching storage directly. Writes change only the user overrides, run one at a time per namespace, and can carry an expected revision so a stale writer is refused instead of silently overwriting a newer one. A provider must be mounted to store the document; without one, nothing changes and configuration stays exactly as composed.
 
-- `documentPath` — absolute path of the provider's user-editable file when it has one; non-file providers leave it `undefined`. Host configuration adapters derive availability from it, while browser protocols expose only a boolean capability and never a filesystem target.
-- `prepareDocument()` — return that path after making the document ready for a native editor. The base implementation returns `documentPath`; a file provider may materialize an absent document first.
-- `register(ns, schema, { base?, applies? })` — returns the owner `SettingsScope` (`get`/`watch`/`update`). The registration is an effect on the calling plugin's fiber: disposing that fiber removes the namespace and its observers. A stored section the schema rejects fails the registration itself; a duplicate namespace fails loud.
-- `describe(options?)` — one descriptor per namespace (`schema.toJSON()` envelope, resolved value, detached `base`/`user` layers, `applies`) for configuration surfaces; a field's presence in `user` is what marks it user-overridden. `describe({ redactSecrets: true })` strips `role('secret')` fields from every layer and adds the `secrets` slot list (`{ path, set }`); every wire surface MUST pass it, and the pure `redactSecrets(schema, value)` walker is exported for other wires.
-- `get(ns)` — resolved value, `undefined` while unregistered.
-- `update(ns, patch)` — deep-merges the plain-object patch into the user section only (never the `base`), validates the resolved candidate, persists through the provider, then commits. Patches may contain only JSON-compatible data: a Date, Map, BigInt, non-finite number, or circular reference rejects with its `$`-rooted path before anything persists (YAML/JSON storage would silently change such values on reload). Validation failure rejects before anything is persisted; a read-only provider (`writable: false`) rejects every write. Writes to one namespace are serialized in call order.
-- `replace(ns, section)` — sets the user section wholesale: the deliberate reset (`replace({})` re-inherits `base` and schema defaults).
-- `mutate(ns, ops)` — applies ordered `{ op: 'set' | 'unset', path }` edits to the section as it stands when the write reaches the front of the queue. This is the removal path for any caller holding an INCOMPLETE view: a configuration UI reads the redacted descriptor, so rebuilding a section from it and replacing wholesale deletes every secret the wire never returned, while an op names the one field it means.
-- Every write takes an optional `expectedRevision`. Each descriptor carries the namespace's `revision`, a monotonic counter over its RAW section; a write whose expectation no longer matches rejects with `SettingsConflictError` (`code: 'SETTINGS_CONFLICT'`, both revisions attached) instead of overwriting the writer that landed first. The write queue orders writes but cannot by itself tell a fresh writer from one holding a stale snapshot.
-- Resolved values are deep-frozen snapshots. Watchers receive `(next, prev)` after each commit: invocations of one callback run asynchronously, one at a time, in commit order (a slow stale invocation can never apply after a newer one), and failures — sync throws and async rejections alike — are contained. After a watch disposer returns, no further invocation starts (one already queued is skipped); an invocation already started still settles. The `settings/updated` event fans out one listener at a time, so one throwing listener cannot starve the rest; an async listener's rejection is contained and logged, which is why `INVARIANT`-coded failures rethrow only from synchronous listeners.
-- Service teardown refuses new writes and watcher starts, then drains every queued write and every started watcher invocation before disposal completes; a write whose registrant fiber was disposed mid-flight still reaches storage but commits and notifies nobody.

-Subclasses implement `writable`, `load()`, and `persist(ns, section)`, optionally override `documentPath` and `prepareDocument()` for one local user-editable file, and push externally observed documents through the protected `publish(doc)`. The base service init loads and publishes the document once before the service becomes injectable; a provider with its own init (watcher, connection) delegates first via `yield* super[Service.init]()`. At publish, each registered namespace re-resolves independently: an invalid section keeps that namespace's last good value and warns — a live reload never takes the process down — while boot-time and registration-time validation fail loud.
+-----
 
-## Events
+<a id="use-this-package"></a>
+## Use this package
 
-`settings/updated (ns, next, prev, source)` fires after each commit; `source` is `update` (in-process write) or `provider` (external change). It never fires for a deep-equal resolved value — it is the consumer-facing event, and a consumer only cares that its value moved.
+Plugins and configuration surfaces use `ctx.settings` to read and change configuration at runtime. The common path: mount a provider, register a namespace with a schema, read and watch the resolved value, and write through the owner scope.
 
-`settings/document-updated (ns, revision)` fires whenever the RAW user section changes, whether or not the resolved value did. Configuration surfaces need this one: storing an override equal to the composition base leaves the resolved value alone but changes what the document says (the field is now overridden, not inherited) and moves the revision every open editor is holding. Listener containment matches `settings/updated`.
+### When to choose it
 
-Both declarations live in the client-safe `./types` subpath export, together with the `SettingsNamespace` and `SettingsUpdateSource` types their signatures name; the package root re-exports those types. A consumer outside the Host compilation face therefore reads the very signature the Host emits instead of restating it.
+Choose settings when a plugin's configuration should be changeable at runtime — by the user editing a document or by a configuration UI — without restarting or re-reading `cordis.yml`. It fits when several plugins each own one configuration namespace, and when a configuration surface must render schemas, mark user-overridden fields, and persist edits. It is unnecessary when configuration is fixed at load time: without a provider mounted, nothing changes and configuration stays exactly as composed.
 
+### Mounting a provider
+
+The service stores nothing by itself; mount a provider such as the shipped file-backed one:
+
+```yaml
+- name: '@deepseek-ai/dsh-settings-file'
+  config:
+    path: /absolute/path/to/settings.yaml
+```
+
+`ctx.settings` appears once the provider is live. The provider README owns the full configuration surface; the generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-settings-file) lists every accepted field.
+
+### Registering a namespace
+
+A plugin registers its own namespace with a schemastery schema, optionally supplying the composition entry as the `base` layer so the resolved value starts from what the deployment already configured:
+
+```text
+import { settingsNamespace } from '@deepseek-ai/dsh-settings'
+
+const scope = ctx.settings.register(settingsNamespace('ui-theme'), ThemeSchema, {
+  base: config,   // composition entry config; the user layer resolves above it
+})
+const theme = scope.get()              // deep-frozen resolved snapshot
+scope.update({ density: 'compact' })   // merges into the user section and persists
+```
+
+`installSettingsSection` packages this wiring for a consumer plugin: while a settings service exists it registers the namespace with the plugin's composition entry as `base`; when the service goes away the plugin falls back to its entry config and keeps working exactly as composed.
+
+### Reading and observing values
+
+`get(ns)` returns the resolved value as a deep-frozen snapshot, `undefined` while the namespace is unregistered. `watch(callback)` invokes the callback after each committed change with `(next, prev)`: invocations of one callback run one at a time in commit order, and failures are contained and logged, so a slow or throwing observer never blocks or breaks other observers.
+
+### Writing values
+
+`update(ns, patch)` deep-merges a plain-object patch into the user section only — never into `base` — validates the resolved candidate, persists through the provider, then commits. `replace(ns, section)` sets the user section wholesale, which is the removal/reset path: `replace({})` re-inherits `base` and schema defaults. `mutate(ns, ops)` applies ordered `{ op: 'set' | 'unset', path }` edits to the section as it stands when the write reaches the front of the queue — the removal path for a caller holding an incomplete (for example redacted) view, because rebuilding a section from what a wire surface returned and replacing it wholesale would delete every field the wire never sent back.
+
+Every write rejects non-JSON-compatible data (a `Date`, `Map`, `BigInt`, non-finite number, or circular reference fails with its `$`-rooted path before anything persists), rejects on a read-only provider, and accepts an optional `expectedRevision`: pass back the `revision` from a descriptor, and a namespace that moved past it refuses the write with `SettingsConflictError` instead of overwriting the writer that landed first.
+
+### Configuration surfaces
+
+`describe()` returns one descriptor per registered namespace: the serialized schema, the resolved value, the detached `base` and `user` layers (a field's presence in `user` marks it user-overridden), the effect timing, and the namespace's revision. Pass `redactSecrets: true` on every wire surface: it strips `role('secret')` fields from every layer and enumerates them as `{ path, set }` slots so a page can render write-only inputs without ever receiving a secret. `documentPath` and `prepareDocument()` expose the provider's user-editable file to a native editor when one exists.
+
+### Events and failures
+
+`settings/updated (ns, next, prev, source)` fires after each committed change — an in-process write (`source: 'update'`) or an externally observed edit (`source: 'provider'`) — and never when the resolved value is deep-equal. `settings/document-updated (ns, revision)` fires whenever the raw user section changed, even when the resolved value did not, which is what an open editor needs to learn that a field went from inherited to overridden. A stored section the schema rejects keeps the namespace's last good value and warns on reload; at registration the same failure rejects the registration itself.

+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the service and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+- **Layered resolution, single user layer.** A namespace's value is schema defaults, then the registrant's composition `base`, then the user document section; writes touch only the user layer, so `replace({})` is a true reset.
+- **Commits are deep-equal gated.** `settings/updated` fires only when the resolved value moved; the raw-section event is separate because configuration surfaces must also learn "inherited became overridden".
+- **Writes are queued and revision-checked.** Per-namespace write queues serialize in call order, and `expectedRevision` is judged at the front of the queue, where the service can tell a fresh writer from one holding a stale snapshot.
+- **Observer and listener failures are contained.** Watcher invocations and event fan-out isolate sync throws and async rejections so one broken observer cannot wedge commits or a provider's reload loop; `INVARIANT`-coded failures rethrow after every listener ran.
+- **Registrations are fiber effects.** Registering a namespace is an effect on the calling plugin's fiber: disposing that fiber removes the namespace and its observers.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Service Definition: namespace brand, registration, resolution, write queue, describe/redaction, events, `installSettingsSection` |
+| [`src/redact.ts`](src/redact.ts) | `redactSecrets` walker: strip `role('secret')` fields and enumerate their slots |
+| [`src/types.ts`](src/types.ts) | Client-safe type surface: event declarations, `SettingsNamespace`, `SettingsUpdateSource` |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion: `settings/updated` fires only for a registered namespace, only on a resolved-value change, with the authoritative value |
+
+### Resolution and write paths
+
+Each write snapshots its input at call time (detaching and validating JSON-shaped data), then queues on the namespace's serialized chain. At the front of the queue the service re-reads the section as it stands, checks `expectedRevision`, merges/replaces/mutates, resolves and validates the candidate through the schema plus the owner's optional `validate`, persists through the provider, and only then commits and emits. A write whose registrant fiber was disposed mid-flight still reaches storage but commits and notifies nobody; teardown refuses new writes and drains queued writes and started watcher invocations before disposal completes.
+
+### Change detection and events
+
+`commit` compares resolved values with the seam's `deepEqualJson` predicate and fans `settings/updated` out one listener at a time. `bumpRevision` compares raw sections and emits `settings/document-updated` with the new revision; it runs independently of the resolved-value check. Both fan-outs contain listener failures the same way.
+
+### Client-safe types
+
+The `./types` subpath export holds the event declarations together with the `SettingsNamespace` and `SettingsUpdateSource` types their signatures name, and the package root re-exports those types. A consumer outside the Host compilation face reads the exact signature the Host emits instead of restating it.

-- **Single user layer** — resolution knows schema defaults, one composition `base`, and one user document; it does not yet record which layer supplied each resolved value.
-- **`redactSecrets` is not a proven wire boundary** — the walker follows `object`/`dict`/`array`, so a `role('secret')` reached only through a union, intersection, or transform is returned VERBATIM with an empty `secrets` list, and `schema.toJSON()` carries a secret field's `.default(...)` to every client. Neither case is rejected; a schema whose secrets are not reachable through the walked containers must not be registered on a wire-exposed namespace. A fail-closed `describeForWire()` — one that refuses a schema it cannot prove safe, and sanitizes the serialized envelope and error text — is the real answer and is deferred.
-- **Cross-process concurrency is provider-defined** — the seam serializes writes per namespace in-process only; concurrent processes converge by provider behavior (the local file provider read-modify-writes under a writer lock, so namespaces survive concurrent writers and same-namespace conflicts resolve last-write-wins).

Open directions, tracked in code TODOs: rename the public `ns` parameter to `namespace` across the API, provider contract, implementations, tests, and consumers; deactivate watchers and await their tails on registration disposal so callbacks cannot outlive the registrant fiber; re-resolve a replacement registration from its persisted section so an in-flight old write cannot leave it stale; and use property-safe object construction so valid JSON keys such as `__proto__` remain own data. The fail-closed `describeForWire()` sanitizer is the deferred answer to the redaction limitation above.

 # @deepseek-ai/dsh-settings
 
 [English](README.md) | 中文
 
-用户设置 Service Definition（`ctx.settings`）。一个提供方持有按 namespace 分节的原始文档；插件注册 namespace schema 并读取分层解析值：schema 默认值，然后注册方的组合 `base`（其 cordis.yml entry 配置子集），最后用户文档分节。不挂载提供方时消费方行为不变：仍只按 entry 配置解析，因此任何组合有无 settings 都能工作。
+## 概述
 
-## 服务 API
+`dsh-settings` 让插件把配置开放给用户运行时修改：插件用一个 schema 注册 namespace，解析值依次尊重 schema 默认值、部署自身的组合 `base` 与用户编辑的文档分节——用户覆盖优先。消费方读取解析值快照并在每次已提交变更后收到通知；配置界面每个 namespace 得到一条 descriptor——schema、当前值、每个字段来自哪一层、生效时机——而无需直接触碰存储。写入只改动用户覆盖、按 namespace 逐个执行，并可携带期望 revision，让持有陈旧快照的写入方被拒绝，而不是悄悄覆盖较新的写入。文档必须由挂载的提供方存储；没有提供方时一切照旧，配置保持组合原样。
 
-- `documentPath` — 提供方拥有用户可编辑文件时，该字段是文件的绝对路径；非文件提供方保留 `undefined`。Host 配置适配器据此派生可用性，而浏览器协议只暴露一个布尔能力，绝不暴露文件系统目标。
-- `prepareDocument()` — 让文档做好供原生编辑器打开的准备后返回该路径。基类实现返回 `documentPath`；文件提供方可先创建缺失的文档。
-- `register(ns, schema, { base?, applies? })` — 返回 owner 的 `SettingsScope`（`get`/`watch`/`update`）。注册是调用方插件 fiber 上的 effect：dispose（资源释放）该 fiber 即移除 namespace 及其观察者。schema 拒绝的存量分节会使注册本身失败；重复 namespace 立即报错。
-- `describe(options?)` — 每个 namespace 一条描述（`schema.toJSON()` 封装、解析值、分离出的 `base`/`user` 层、`applies`），供配置界面使用；字段出现在 `user` 中即标记其被用户覆盖。`describe({ redactSecrets: true })` 从每一层剥离 `role('secret')` 字段，并附加 `secrets` slot 列表（`{ path, set }`）；每个协议接口都必须传入它，纯遍历器 `redactSecrets(schema, value)` 已导出，供其他 wire 使用。
-- `get(ns)` — 解析值；未注册时为 `undefined`。
-- `update(ns, patch)` — 把普通对象 patch 深合并进用户分节（绝不合并进 `base`），校验解析候选值，经提供方持久化后提交。patch 只能包含与 JSON 兼容的数据：Date、Map、BigInt、非有限数或循环引用会在任何内容持久化前被拒绝，并给出以 `$` 为根的路径（YAML/JSON 存储在重载时会静默改变这类值）。校验失败在持久化前拒绝；只读提供方（`writable: false`）拒绝一切写入。同一 namespace 的写入按调用顺序串行。
-- `replace(ns, section)` — 整体替换用户分节：这是刻意的重置（`replace({})` 重新继承 `base` 与 schema 默认值）。
-- `mutate(ns, ops)` — 在写入排到队首那一刻的分节上，按序施加 `{ op: 'set' | 'unset', path }` 编辑。这是任何持有**不完整**视图的调用方的删除路径：配置 UI 读到的是脱敏后的 descriptor，据此重建分节再整体替换，会把 wire 从未回传的每个机密都删掉，而一条 op 只点名它真正要改的那个字段。
-- 每次写入都可携带可选的 `expectedRevision`。每个 descriptor 都带有该 namespace 的 `revision`——一个针对其**原始**分节的单调计数器；期望值不再匹配的写入会以 `SettingsConflictError`（`code: 'SETTINGS_CONFLICT'`，并附上两个 revision）被拒绝，而不是覆盖先完成写入的写入方。写队列只保证写入的先后次序，它本身分辨不出持有新鲜快照的写入方与持有陈旧快照的写入方。
-- 解析值是深冻结快照。每次提交后观察者收到 `(next, prev)`：同一回调的调用异步、逐次、按提交顺序执行（慢的旧调用绝不会晚于较新的调用生效），异常——同步抛出与异步拒绝——均被隔离。watch 的 disposer 返回后不再启动新的调用（已排队的那一次会被跳过）；已启动的调用仍会结算。`settings/updated` 事件逐监听器扇出，一个抛错的 listener 不会饿死其余 listener；异步 listener 的拒绝会被隔离并记入日志，这正是 `INVARIANT` 编码的失败只从同步 listener 重新抛出的原因。
-- 服务卸载先拒绝新写入与观察者调用的启动，再排干全部排队写入与已启动的观察者调用后才完成；registrant fiber 在写入途中被 dispose 时，该写入仍到达存储，但不会提交，也不会通知任何人。

-子类实现 `writable`、`load()`、`persist(ns, section)`，可选择为一个本地用户可编辑文件重写 `documentPath` 与 `prepareDocument()`，并通过受保护的 `publish(doc)` 推入外部观察到的文档。基类服务 init 在服务可注入前加载并发布一次文档；拥有自有 init（watcher、连接）的提供方会先通过 `yield* super[Service.init]()` 委托给基类。publish 时每个已注册 namespace 独立重解析：非法分节保留该 namespace 的最后可用值并告警——热重载绝不拖垮进程；启动期与注册期校验则立即报错。
+-----
 
-## 事件
+<a id="use-this-package"></a>
+## 使用本包
 
-`settings/updated (ns, next, prev, source)` 在每次提交后触发；`source` 为 `update`（进程内写入）或 `provider`（外部变更）。解析值深相等时绝不触发——它面向消费方，而消费方只关心自己的值有没有变。
+插件与配置界面通过 `ctx.settings` 在运行时读取并修改配置。常用路径：挂载提供方、用 schema 注册 namespace、读取并观察解析值，并通过 owner scope 写入。
 
-`settings/document-updated (ns, revision)` 在**原始**用户分节发生变化时触发，无论解析值是否随之改变。配置界面需要的是这一个：存入一个与组合 `base` 相同的覆盖值不会改变解析值，却改变了文档的说法（该字段从继承变成了覆盖），也推进了每个已打开编辑器所持有的 revision。监听器的异常隔离方式与 `settings/updated` 相同。
+### 何时选择
 
-两条声明都住在 client-safe 的 `./types` 子路径出口，与其签名点名的 `SettingsNamespace`、`SettingsUpdateSource` 类型同处一处；包根继续 re-export 这些类型。于是 Host 编译面之外的消费方读到的正是 Host 发射的那一份签名，而不必再写一遍。
+当插件的配置需要在运行时可变——用户编辑文档或配置界面修改——且无需重启或重读 `cordis.yml` 时，选择设置服务。它适合多个插件各拥有一个配置 namespace、以及配置界面需要渲染 schema、标记用户覆盖字段并持久化编辑的场景。当配置在加载时固定则没有必要：没有挂载提供方时一切照旧，配置保持组合原样。
 
+### 挂载提供方
+
+服务本身不存储任何内容；请挂载一个提供方，例如随附的文件型提供方：
+
+```yaml
+- name: '@deepseek-ai/dsh-settings-file'
+  config:
+    path: /absolute/path/to/settings.yaml
+```
+
+提供方上线后 `ctx.settings` 即出现。完整配置面由提供方 README 负责；生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-settings-file)列出每个受支持字段。
+
+### 注册 namespace
+
+插件用 schemastery schema 注册自己的 namespace，并可选地把组合配置作为 `base` 层传入，让解析值从部署已配置的内容起步：
+
+```text
+import { settingsNamespace } from '@deepseek-ai/dsh-settings'
+
+const scope = ctx.settings.register(settingsNamespace('ui-theme'), ThemeSchema, {
+  base: config,   // composition entry config; the user layer resolves above it
+})
+const theme = scope.get()              // deep-frozen resolved snapshot
+scope.update({ density: 'compact' })   // merges into the user section and persists
+```
+
+`installSettingsSection` 为消费方插件封装了这套接线：只要设置服务存在，它就用插件的组合配置作为 `base` 注册 namespace；服务消失时插件回退到组合配置，行为与原先完全一致。
+
+### 读取与观察值
+
+`get(ns)` 以深冻结快照返回解析值，namespace 未注册时为 `undefined`。`watch(callback)` 在每次已提交变更后以 `(next, prev)` 调用回调：同一回调的调用按提交顺序逐个执行，异常被隔离并记入日志，因此慢或抛错的观察者绝不会阻塞或破坏其他观察者。
+
+### 写入值
+
+`update(ns, patch)` 把普通对象 patch 深合并进用户分节——绝不进 `base`——校验解析候选值、经提供方持久化后提交。`replace(ns, section)` 整体替换用户分节，是删除/重置路径：`replace({})` 重新继承 `base` 与 schema 默认值。`mutate(ns, ops)` 在写入排到队首那一刻的分节上按序施加 `{ op: 'set' | 'unset', path }` 编辑——这是持有不完整（例如脱敏后）视图的调用方的删除路径，因为按协议接口返回的内容重建分节再整体替换，会删掉协议从未回传的每个字段。
+
+每次写入都会拒绝与 JSON 不兼容的数据（`Date`、`Map`、`BigInt`、非有限数或循环引用会在任何内容持久化前以 `$` 为根的路径报错）、拒绝只读提供方上的写入，并可接受可选的 `expectedRevision`：把 descriptor 中的 `revision` 传回，namespace 已越过该值时写入会被 `SettingsConflictError` 拒绝，而不是覆盖先完成写入的一方。
+
+### 配置界面
+
+`describe()` 为每个已注册 namespace 返回一条 descriptor：序列化 schema、解析值、分离的 `base` 与 `user` 层（字段出现在 `user` 中即标记为用户覆盖）、生效时机与 namespace 的 revision。每个协议接口都必须传入 `redactSecrets: true`：它从每一层剥离 `role('secret')` 字段，并把它们枚举为 `{ path, set }` slot，让页面可以渲染只写输入而不接触任何机密。`documentPath` 与 `prepareDocument()` 在提供方拥有用户可编辑文件时把它暴露给原生编辑器。
+
+### 事件与失败
+
+`settings/updated (ns, next, prev, source)` 在每次已提交变更后触发——进程内写入（`source: 'update'`）或外部观察到的编辑（`source: 'provider'`）——解析值深相等时绝不触发。`settings/document-updated (ns, revision)` 在原始用户分节发生变化时触发，即使解析值没有变——已打开的编辑器正需要它来得知字段从继承变为覆盖。schema 拒绝的存量分节在重载时保留该 namespace 的最后可用值并告警；注册时同样的失败会直接拒绝注册。

+## 理解实现
+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释服务背后的设计决策并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+- **分层解析，单一用户层。** namespace 的值依次为 schema 默认值、注册方的组合 `base`、用户文档分节；写入只触碰用户层，因此 `replace({})` 是真正的重置。
+- **提交以深相等为门槛。** 只有解析值变化时 `settings/updated` 才触发；原始分节事件独立存在，因为配置界面还必须得知「继承变成了覆盖」。
+- **写入排队并做 revision 检查。** 每个 namespace 的写队列按调用顺序串行，`expectedRevision` 在队首判断——那里服务才能分辨持有新鲜快照的写入方与持有陈旧快照的写入方。
+- **观察者与监听器异常被隔离。** watcher 调用与事件扇出隔离同步抛出与异步拒绝，一个坏掉的观察者不会卡死提交或提供方的重载循环；`INVARIANT` 编码的失败在所有监听器执行完后重新抛出。
+- **注册是 fiber 上的 effect。** 注册 namespace 是调用方插件 fiber 上的 effect：dispose（资源释放）该 fiber 即移除 namespace 及其观察者。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Service Definition：namespace brand、注册、解析、写队列、describe/脱敏、事件、`installSettingsSection` |
+| [`src/redact.ts`](src/redact.ts) | `redactSecrets` 遍历器：剥离 `role('secret')` 字段并枚举其 slot |
+| [`src/types.ts`](src/types.ts) | 客户端安全类型面：事件声明、`SettingsNamespace`、`SettingsUpdateSource` |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件：`settings/updated` 只对已注册 namespace、只在解析值变化时、且携带权威值触发 |
+
+### 解析与写入路径
+
+每次写入都在调用时对输入做快照（分离并校验 JSON 形状的数据），然后排上该 namespace 的串行链。在队首，服务按当前状态重读分节、检查 `expectedRevision`、合并/替换/编辑、经 schema 与 owner 的可选 `validate` 解析并校验候选值、经提供方持久化，然后才提交并发出事件。registrant fiber 在写入途中被 dispose 的写入仍到达存储，但不会提交、也不会通知任何人；卸载先拒绝新写入，并排干排队写入与已启动的 watcher 调用后才完成。
+
+### 变更检测与事件
+
+`commit` 用 seam 的 `deepEqualJson` 谓词比较解析值，并逐监听器扇出 `settings/updated`。`bumpRevision` 比较原始分节并携带新 revision 发出 `settings/document-updated`；它与解析值检查相互独立。两个扇出以相同方式隔离监听器异常。
+
+### 客户端安全类型
+
+`./types` 子路径出口持有事件声明及其签名点名的 `SettingsNamespace`、`SettingsUpdateSource` 类型，包根继续 re-export 这些类型。于是 Host 编译面之外的消费方读到的正是 Host 发射的那一份签名，而不必再写一遍。

 ## 模型体验
 
-间接生效：消费方插件从各自 namespace 解析影响模型的值（例如默认模型路由）；效果由各消费方自己的接口文档说明。
+间接生效：消费方插件拥有任何由设置值喂给的模型面内容；本服务只存储并解析用户设置，自身不注册任何模型面内容。
 
 #### KV Cache 影响
 
 无直接失效；把设置值纳入请求前缀的消费方负责该变更。
 
-## 已知限制与暂缓事项
+## 已知限制与延期工作
 
-- **单一用户层** — 解析只认识 schema 默认值、一个组合 `base` 与一个用户文档；它尚未记录每个解析值由哪一层提供。
-- **`redactSecrets` 并非一条可被证明的协议边界**：walker 只跟随 `object`/`dict`/`array`，因此只能经由 union、intersection 或 transform 抵达的 `role('secret')` 会被**原样**返回，且 `secrets` 列表为空；而 `schema.toJSON()` 会把 secret 字段的 `.default(...)` 一并带给每个客户端。这两种情况都不会被拒绝；机密无法经由被遍历的容器抵达的 schema，绝不可注册到暴露于协议的 namespace 上。真正的答案是一个 fail-closed 的 `describeForWire()`——它拒绝自己无法证明安全的 schema，并对序列化封装与错误文本做净化——此项暂缓。
-- **跨进程并发由提供方定义** — seam 仅在进程内按 namespace 串行化写入；跨进程并发按提供方行为收敛（本地文件提供方在写锁下读-改-写，因此 namespace 在并发写入者下不会丢失，同 namespace 冲突按后写胜出解决）。

 # shell/ — bash capability family
 
 English | [中文](README.zh.md)
 
-The capability family spans the canonical executor seam, its implementations, the shared shell environment, and the model-facing tools. All are **product** packages.
+## Summary
+
+The shell group provides command execution to agents: run a foreground command and read its bounded output, or start a background process and poll it, on POSIX with Bash and on Windows with PowerShell. Exactly one executor implementation is mounted per composition; the sandboxing executors confine every command through the sandbox capability, and the model-facing `bash` and `pwsh` tools sit on top of whichever executor is mounted. Choose a Bash executor for POSIX, a PowerShell executor for Windows, and pick the sandboxing variant when commands need file-level confinement.

 # shell/ — bash 能力家族
 
 [English](README.md) | 中文
 
-该能力家族涵盖规范执行器 seam、其实现、共享 shell 环境和面向模型的工具。这些全是**产品**包。
+## 概述
+
+shell 组为 agent 提供命令执行能力：运行前台命令并读取其有界输出，或启动后台进程并轮询它——在 POSIX 上用 Bash，在 Windows 上用 PowerShell。每个组合恰好挂载一个执行器实现；沙箱执行器会通过沙箱能力限制每条命令，面向模型的 `bash` 与 `pwsh` 工具则位于所挂载执行器之上。POSIX 选择 Bash 执行器，Windows 选择 PowerShell 执行器；命令需要文件级隔离时选择沙箱变体。

 English | [中文](README.zh.md)
 
-Local Service Provider for the `@deepseek-ai/dsh-shell` executor seam over the [`@deepseek-ai/dsh-subprocess`](../../subprocess/subprocess/README.md) service: `LocalBashExecutor` spawns `bash -c <command>` per call as a managed process group through `ctx.subprocess`, and owns everything bash-shaped — command defaulting and caps, timeout/cancel classification, the model-friendly terminal environment, and the model-facing stdout/stderr merge for background reads. Group mechanics (bounded spill-backed output, credential scrub, kill escalation, disposal) are the subprocess service's.
+## Summary
 
-The package root exports the default and named `LocalBashExecutor` plugin plus its `Config`.
+`dsh-bash-local` is the default Bash executor for POSIX: every command runs as a fresh, non-login `bash -c` process with no rc files, so no shell state survives between calls. It applies configured budgets — working directory, timeout, output caps — to each command, classifies timeouts and cancellations, and returns bounded output with spill-file recovery when a stream overflows. Commands run with the harness process's own authority: this executor confines nothing, so compose `dsh-bash-sandbox` when commands need the sandbox capability. The model-facing `bash` tool talks to it once it is mounted.

+## Use this package
+
+Mount this executor when a composition needs Bash command execution on POSIX without confinement. It registers as `ctx.shell`, and the model-facing `bash` tool works over it immediately: an agent calls the tool, and the command runs as a fresh `bash -c` process with the budgets below.
+
+### Minimal configuration
+
+Load the executor with the budgets you want; every field has a default, so the smallest composition is the plugin entry alone. The settings provider (when composed) layers a user section over this entry, so budgets can change at runtime without a reload (see [Adjusting budgets at runtime](#adjusting-budgets-at-runtime)).
 
 ```yaml
 - id: bash
   name: '@deepseek-ai/dsh-bash-local'
   config:
-    cwd: /path/to/workspace   # default: process.cwd()
-    timeoutMs: 120000          # default foreground timeout
-    maxTimeoutMs: 600000       # cap for per-call overrides
-    maxOutputBytes: 64000      # per-stream in-memory cap; overflow spills to disk
-    maxSpillBytes: 67108864    # per-stream full-output spill cap
-    graceMs: 3000              # kill escalation and post-exit pipe-drain grace
+    cwd: /path/to/workspace
+    timeoutMs: 120000
 ```
 
-## Behavior
+| Field | Default | Meaning |
+|---|---|---|
+| `cwd` | `process.cwd()` | Default working directory for commands |
+| `timeoutMs` | `120,000` | Default foreground timeout, in milliseconds |
+| `maxTimeoutMs` | `600,000` | Cap for per-call timeout overrides |
+| `maxOutputBytes` | `64,000` | Per-stream in-memory output cap; overflow spills to a temp file |
+| `maxSpillBytes` | `67,108,864` | Per-stream full-output spill cap |
+| `graceMs` | `3,000` | Grace period for kill escalation and post-exit pipe draining |
 
-- **Spawn per call, no shell state** — every call is a fresh non-login `bash -c` with no rc files.
-- **The composition entry is a layer, not the last word** — when a settings provider is composed, this executor registers the capability's [`bash` namespace](../shell/README.md) with the entry above as its base, so a user section in `settings.yaml` layers over it and the next command runs with the new budgets. Values the schema cannot judge (positive and finite, the `graceMs` timer bound) are refused at the write, leaving the running executor on its last good section; without a provider, or after one detaches, the composition entry is what runs.
-- **Configured budgets over managed groups** — `resolve()` fills `workdir`/`timeoutMs`/`stdoutMaxBytes` from config, and every spawn hands the service explicit byte caps, spill cap, and `graceMs`. The grace must be positive, finite, and no greater than [`MAX_TIMER_DELAY_MS`](../../util/timeout/README.md), so Node can represent it with one timer. Process-group kills, post-exit pipe draining, tail retention, and bounded spill files are [`dsh-subprocess-local`](../../subprocess/subprocess-local/README.md) mechanics. A foreground `ShellExecRequest.stdoutMaxBytes` can raise stdout's capture budget for one trusted caller; stderr and background runs still use `maxOutputBytes`.
-- **Timeout and cancel classification** — `run()` fuses its config-clamped timeout with the caller's signal through one deadline; only the executor's own timeout reports `timedOut`, an upstream cancel reports `aborted`, and a self-signaled command reports neither ([timeout-library Agent Note](../../../.agents/notes/implemented/architecture/2026-07-06-timeout-deadline-library.md)).
-- **Model-friendly terminal env** — `NO_COLOR=1 TERM=dumb PAGER=cat GIT_PAGER=cat` prevents pagers and ANSI color from garbling results. These values merge as ordinary env under the service's credential scrub and `DSH_*` channel rules; an explicit caller entry still wins. See the [stdin/env Agent Note](../../../.agents/notes/implemented/architecture/2026-06-30-bash-stdin-env-trusted-plugin-api.md) and [managed environment Agent Note](../../../.agents/notes/implemented/feature/2026-07-10-agent-session-identity-and-log-location.md).
-- **Background processes** — `start()` returns a live `ShellProcess` handle immediately with no timeout, and `readOutput()` merges offset-based stdout/stderr reads into one consuming delta, placing stderr under a `[stderr]` marker when present. A running process belongs to the subprocess service, survives executor reloads, and is killed and joined on service disposal. Job ids, ownership, polling, and notices belong to the generic [`ctx.jobs` runtime](../../jobs/jobs/README.md), which the tool layer registers the handle with.
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-bash-local) is the exhaustive source for every accepted field and its JSDoc.
 
+### Running commands
+
+Run a command with `run` and read its output from the result. A nonzero exit, a timeout, or a cancellation resolves with a descriptive result — only infrastructure failures reject. Per-call `timeoutMs` overrides are capped by the configuration, while `workdir` falls back to the configured default when unset; a trusted foreground caller can also raise the stdout capture budget for one call, while stderr and background runs keep `maxOutputBytes`. The environment is model-friendly by default: `NO_COLOR=1 TERM=dumb PAGER=cat GIT_PAGER=cat` keep pagers and ANSI colors from garbling output, and an explicit caller-provided entry still wins.
+
+```text
+const result = await ctx.shell.run(ctx.shell.resolve({ command: 'ls -la' }))
+if (result.timedOut) console.log('timed out after', result.timeoutMs)
+```
+
+### Background processes
+
+Call `start` to run a command in the background; it returns a handle immediately and no timeout applies. `readOutput()` merges the stream deltas into one consuming read, marking stderr under a `[stderr]` section; `kill()` stops the process group; `done` settles when the process closes and never rejects. Job ids, ownership, polling, and notices belong to the generic `ctx.jobs` runtime, which the tool layer registers the handle with.
+
+<a id="adjusting-budgets-at-runtime"></a>
+### Adjusting budgets at runtime
+
+When a settings provider is composed, this executor registers the capability's shared `shell` settings namespace with the composition entry as its base, so a user section in `settings.yaml` layers over it and the next command runs with the new budgets. Values the schema cannot judge — positive and finite numbers, and the `graceMs` timer bound — are refused at the write, leaving the running executor on its last good section; without a provider, the composition entry is what runs.

+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design of the executor and points at the code that realizes it; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The executor is a Service Provider for the `ctx.shell` seam built on the subprocess capability: it owns everything bash-shaped — command defaulting and caps, deadline fusion and cause classification, the model-friendly terminal environment, and the background read merge — while process-group mechanics (bounded spill-backed output, credential scrub, kill escalation, disposal) belong to the subprocess service. Every call spawns a fresh non-login `bash -c` with no rc files, so commands are deterministic and shell state never leaks between calls.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `LocalBashExecutor`, `Config`, settings-section wiring |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; contracts are enforced at the owning seam) |
+| `tests/executor.spec.ts` | Exercised behavior: budgets, classification, background handles, ownership |
+| `tests/settings.spec.ts` | Settings layering over the composition entry |
+
+### Main flow
+
+A call runs through three steps: `resolve()` fills `workdir`/`timeoutMs`/`stdoutMaxBytes` from config (capping per-call overrides); `run` fuses the config-clamped timeout with the caller's abort signal into one deadline and spawns `['bash', '-c', command]` through `ctx.subprocess` with explicit byte caps and the `graceMs`; the settled subprocess outcome is classified — only the executor's own timeout reports `timedOut`, an upstream cancel reports `aborted`, a self-signaled command reports neither — and projected into a `ShellRunResult` with collected output.
+
+### Invariants and ownership
+
+- The `graceMs` budget must be positive, finite, and no greater than `MAX_TIMER_DELAY_MS` so Node can represent it with one timer; invalid values are refused where they are written.
+- Environment layering is fixed: terminal overrides first, then the caller's `env`, then the trusted `dshEnv` snapshot last; the subprocess service scrubs ambient credentials and inherited `DSH_*` names independently.
+- A background process belongs to the subprocess service: it survives an executor-only reload and is killed and joined when the service disposes.

 [English](README.md) | 中文
 
-`@deepseek-ai/dsh-shell` 执行器 seam 的本地 Service Provider，构建在 [`@deepseek-ai/dsh-subprocess`](../../subprocess/subprocess/README.zh.md) 服务之上：`LocalBashExecutor` 每次调用都通过 `ctx.subprocess` 把 `bash -c <command>` 作为受管进程组 spawn，并负责所有 Bash 层职责（命令默认值补全与上限、超时与取消分类、适合模型的终端环境，以及后台读取时面向模型的 stdout/stderr 合并）。以 spill 文件兜底的有界输出、凭据清除、kill 升级和 dispose（资源释放）等进程组机制则由 subprocess 服务负责。
+## 概述
 
-包根目录导出默认与具名的 `LocalBashExecutor` 插件及其 `Config`。
+`dsh-bash-local` 是 POSIX 上的默认 Bash 执行器：每条命令都以全新的非登录 `bash -c` 进程运行，不读取 rc 文件，因此调用之间不会残留任何 shell 状态。它会为每条命令应用已配置的预算——工作目录、超时、输出上限——对超时与取消进行分类，并在流溢出时返回有界输出与 spill 文件恢复。命令以 harness 进程自身的权限运行：本执行器不做任何隔离，需要沙箱能力时请组合 `dsh-bash-sandbox`。挂载后，面向模型的 `bash` 工具会与它对接。

+
+### 最小配置
+
+按你需要的预算加载执行器；每个字段都有默认值，因此最小的组合就是单独一个插件条目。当组合了设置提供方时，用户段会叠加在该条目之上，预算无需重载即可在运行时变更（见[运行时调整预算](#adjusting-budgets-at-runtime)）。

-- **每次调用都 spawn，不保留 shell 状态**：每次调用都启动新的非登录 `bash -c`，且不读取 rc 文件。
-- **组装条目是一层，而不是最终值**：当组装中存在 settings 提供方时，本执行器以上面的条目为 base 注册该能力的 [`bash` 命名空间](../shell/README.zh.md)，因此 `settings.yaml` 中的用户段会叠加其上，下一条命令即按新预算运行。schema 无法判定的值（正有限、`graceMs` 的定时器上界）会在写入时被拒绝，运行中的执行器保持它最后一份可用的段；没有提供方、或提供方脱离之后，运行的就是组装条目。
-- **在受管进程组之上应用配置预算**：`resolve()` 从配置补全 `workdir`／`timeoutMs`／`stdoutMaxBytes`，每次 spawn 都向服务传入显式的字节上限、spill 上限与 `graceMs`。该宽限期须为正有限值，且不得大于 [`MAX_TIMER_DELAY_MS`](../../util/timeout/README.zh.md)，这样 Node 就能用一个定时器表示它。进程组终止、退出后管道排空、尾部保留与有界 spill 文件是 [`dsh-subprocess-local`](../../subprocess/subprocess-local/README.zh.md) 的机制。前台 `ShellExecRequest.stdoutMaxBytes` 可为某个受信任调用方提高单次 stdout 捕获预算；stderr 和后台运行仍使用 `maxOutputBytes`。
-- **超时与取消分类**：`run()` 通过同一个 deadline 把经配置钳位的超时与调用方的信号融合；只有执行器自身的超时报告 `timedOut`，上游取消报告 `aborted`，自身因信号终止的命令两者皆不报告（见[超时库 Agent Note](../../../.agents/notes/implemented/architecture/2026-07-06-timeout-deadline-library.zh.md)）。
-- **适合模型的终端环境**：`NO_COLOR=1 TERM=dumb PAGER=cat GIT_PAGER=cat` 防止分页器与 ANSI 颜色破坏结果。这些值作为普通 env 合并，遵循服务的凭据清除与 `DSH_*` 通道规则；调用方的显式条目依旧优先。详见 [stdin/env Agent Note](../../../.agents/notes/implemented/architecture/2026-06-30-bash-stdin-env-trusted-plugin-api.zh.md) 与 [受管环境 Agent Note](../../../.agents/notes/implemented/feature/2026-07-10-agent-session-identity-and-log-location.zh.md)。
-- **后台进程**：`start()` 会立即返回活动的 `ShellProcess` 句柄且不应用超时；`readOutput()` 把基于偏移量的 stdout/stderr 读取合并为一条消费式增量，并在存在 stderr 时将其置于 `[stderr]` 标记下。运行中的进程属于 subprocess 服务，可在执行器重载后存活，并在服务 dispose 时被终止且等待退出。job id、所有权、轮询和通知属于通用 [`ctx.jobs` 运行时](../../jobs/jobs/README.zh.md)，工具层会在其中注册该句柄。

+### 运行命令
+
+用 `run` 运行命令并从结果读取输出。非零退出、超时或取消都会 resolve 为描述性结果——只有基础设施失败才 reject。每次调用的 `timeoutMs` 覆盖值受配置上限约束，`workdir` 未设置时则回退到配置的默认值；受信任的前台调用方还可以为单次调用提高 stdout 捕获预算，而 stderr 与后台运行仍使用 `maxOutputBytes`。环境默认面向模型：`NO_COLOR=1 TERM=dumb PAGER=cat GIT_PAGER=cat` 可防止分页器与 ANSI 颜色破坏输出，调用方显式提供的条目仍然优先。
+
+```text
+const result = await ctx.shell.run(ctx.shell.resolve({ command: 'ls -la' }))
+if (result.timedOut) console.log('timed out after', result.timeoutMs)
+```
+
+### 后台进程
+
+调用 `start` 即可在后台运行命令；它立即返回句柄，且不应用任何超时。`readOutput()` 把流增量合并为一次消费式读取，并在 `[stderr]` 分段下标记 stderr；`kill()` 停止进程组；`done` 在进程关闭时结算且绝不 reject。job id、所有权、轮询与通知属于通用 `ctx.jobs` 运行时，工具层会把句柄注册进去。
+
+<a id="adjusting-budgets-at-runtime"></a>
+### 运行时调整预算
+
+当组合了设置提供方时，本执行器以组合条目为 base 注册该能力共享的 `shell` 设置命名空间，因此 `settings.yaml` 中的用户段会叠加其上，下一条命令即按新预算运行。schema 无法判定的值——正有限数字与 `graceMs` 的定时器上界——会在写入时被拒绝，运行中的执行器保持它最后一份可用的段；没有提供方时，运行的就是组合条目。

+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释执行器的设计并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计概念
+
+本执行器是基于 subprocess 能力的 `ctx.shell` seam 的 Service Provider：它负责所有 bash 层职责——命令默认化与上限、deadline 融合与原因分类、面向模型的终端环境，以及后台读取合并——而进程组机制（有界 spill 输出、凭据清除、终止升级、dispose（资源释放））属于 subprocess 服务。每次调用都 spawn 全新的非登录 `bash -c`，不读取 rc 文件，因此命令是确定性的，shell 状态绝不会在调用之间泄漏。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：`LocalBashExecutor`、`Config`、设置段接线 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；约定在所属 seam 处执行） |
+| `tests/executor.spec.ts` | 已演练的行为：预算、分类、后台句柄、归属 |
+| `tests/settings.spec.ts` | 设置段叠加在组合条目之上 |
+
+### 主要流程
+
+一次调用分三步：`resolve()` 从配置填充 `workdir`/`timeoutMs`/`stdoutMaxBytes`（并限制每次调用的覆盖值）；`run` 把按配置钳位的超时与调用方的中止信号融合为一个 deadline，再以显式字节上限与 `graceMs` 通过 `ctx.subprocess` spawn `['bash', '-c', command]`；结算的 subprocess 结果被分类——只有执行器自身的超时报告 `timedOut`，上游取消报告 `aborted`，自身因信号终止的命令两者皆不报告——并投影为带收集输出的 `ShellRunResult`。
+
+### 不变式与归属
+
+- `graceMs` 预算必须为正有限值且不大于 `MAX_TIMER_DELAY_MS`，这样 Node 就能用一个定时器表示它；无效值在写入处被拒绝。
+- 环境分层固定：先是终端覆盖值，然后是调用方的 `env`，最后才是受信任的 `dshEnv` 快照；subprocess 服务独立清除环境中的凭据与继承的 `DSH_*` 名称。
+- 后台进程属于 subprocess 服务：它能在仅重载执行器后存活，并在服务 dispose 时被终止并 join。

 # @deepseek-ai/dsh-bash-sandbox
 
 English | [中文](README.zh.md)
 
-Sandbox-consuming Service Provider for the [`@deepseek-ai/dsh-shell`](../shell/) executor seam. Load it **instead of** `@deepseek-ai/dsh-bash-local`, together with a [`ctx.sandbox`](../../sandbox/sandbox/) provider (e.g. [`@deepseek-ai/dsh-sandbox-local`](../../sandbox/sandbox-local/)) and a [`ctx.sandboxPolicy`](../../sandbox/sandbox-policy/) (which owns the default mode + workspace root, shared with the sandboxed filesystem) — no alternate tool plugin is needed; `dsh-tool-bash` detects the executor's `sandboxMode` capability and adds the escalation fields.
+## Summary
 
-The package root exports the default and named `SandboxBashExecutor` plugin plus its `Config`; result-classification helpers stay internal.
+`dsh-bash-sandbox` is the sandbox-consuming Bash executor: every command runs as a fresh `bash -c` process confined through the `ctx.sandbox` capability instead of with the harness process's full file authority. Each settled result carries the mode the command ran under, whether the sandbox denied a file operation, and how completely the selected runner enforced the requested mode. When no runner can enforce a confined mode, the call fails closed with a structured `SANDBOX_UNAVAILABLE` error rather than running unconfined. It is the confining sibling of `dsh-bash-local` — sharing its process mechanics — and the tool layer's escalation fields appear only while it is mounted.
 
-Every command is confined by handing the provider the exact `['bash', '-c', command]` argv this executor is about to spawn and spawning the returned argv directly. With the shipped native runners, the inner Bash retains shell semantics and evaluates `BASH_ENV` only after the runner establishes confinement. WHICH platform runner confines it — and whether one is usable at all (fail closed with a structured `SANDBOX_UNAVAILABLE` error, never a silent unconfined run) — is the provider's concern; this package owns the bash side only.

+## Use this package
+
+Mount this executor instead of `dsh-bash-local` when commands must not run with the harness process's full file authority. It registers as `ctx.shell` and requires a `ctx.sandbox` provider plus `ctx.sandboxPolicy`; the model-facing `bash` tool works over it unchanged and advertises the `sandbox_permissions`/`justification` escalation fields.
+
+### When to choose it
+
+Choose it when a deployment needs file-level confinement for Bash commands: the configured policy decides the default mode and workspace root, and each session can run under a different mode per call through the tool's escalation flow. The modes govern file effects only — network stays unrestricted and process visibility is backend-specific. For unconfined execution, or when no sandbox backend is available on the platform, mount `dsh-bash-local` instead.
+
+### Modes and file effects
 
 | Mode | File effects |
 |---|---|
-| `read-only` (default) | No writes anywhere (of `/dev`, only the `/dev/null` node is writable, so `>/dev/null` keeps working) |
-| `workspace-write` | Writes only under `workspaceRoot` + `/tmp` (ephemeral under bwrap, the host `/tmp` under Landlock, `/private/tmp` plus the per-user temp dir under Seatbelt) |
-| `danger-full-access` | No confinement; the provider is never consulted. Foreground results carry `sandbox: { mode, denied: false }`; background process handles carry no sandbox facts. |
+| `read-only` (default) | No writes anywhere; of `/dev`, only the `/dev/null` node is writable, so `>/dev/null` keeps working |

-Semantics:
+### Minimal configuration
 
-- **Denials are result facts.** A failed run whose stderr carries the selected backend's own denial dialect — the signatures the provider stamps on every wrap (EROFS text under bwrap, EACCES under Landlock, EPERM under Seatbelt) — is reported as `ShellRunResult.sandbox.denied: true` (conservative classification, read from the collected stderr tail); every CONFINED run also carries the mode it executed under (`result.sandbox.mode`) and the provider's enforcement completeness (`result.sandbox.enforcement`: `full`, or `partial` on an older Landlock ABI).
-- **The runner path or syscall must match.** Before a process starts, a rejection is attributed to the runner only when the caller-owned workdir is independently usable and Node reports `ENOENT` or `EACCES` with either an `error.path` equal to provider argv[0] or, when `error.path` is absent, an exact `syscall: 'spawn <runner>'`. A present path also requires `syscall: 'spawn'` or the exact `spawn <runner>`. This covers a missing runner, a non-executable runner, or an executable script whose shebang interpreter is unavailable. A bare `syscall: 'spawn'` without an exact error path, any other code, an invalid or unusable workdir, a resource failure, an unrelated syscall, or an unstructured rejection retains the local executor's command-start failure semantics. Foreground execution throws `SANDBOX_UNAVAILABLE` with the original spawn detail, while asynchronous background settlement stamps `runnerFailed: true` and `denied: false`. If a `SubprocessRuntime` synchronously throws the same runner-identifying `ENOENT`/`EACCES` shape, background start throws `SANDBOX_UNAVAILABLE`; other synchronous errors propagate unchanged. After a process starts, a rule's optional exit-code check and a remaining fatal stderr line must both match after exact informational-line exclusions. A match takes priority over denial; foreground execution throws `SANDBOX_UNAVAILABLE` with the matched fatal line, while a settled background process stamps `process.sandbox.runnerFailed`, which the bash producer renders through generic `job_output`. Confined background handles retain their mode/enforcement facts and release per-process accounting in either path.
-- **Deployment fallback, per-call policy.** [`ctx.sandboxPolicy`](../../sandbox/sandbox-policy/) resolves a complete `SandboxExecutionPolicy` for every tool call: the calling session supplies its mode override and immutable cwd root, while deployment config supplies the fallbacks for agentless calls. An approved escalation changes only that policy's mode; its session root stays attached. `resolve()` carries the policy onto the spec, so overlapping commands from different projects run, classify, and report under their own roots and modes. The capability fact `ctx.shell.sandboxMode` reports the configured default so the tool layer advertises escalation only when this executor is mounted; the static bash tool description separately owns denial and escalation guidance.
-- **File effects only.** The mode vocabulary claims only file effects. Network stays unrestricted; process visibility is backend-specific and documented by [`dsh-sandbox-local`](../../sandbox/sandbox-local/).
-- Process mechanics (spawn, process-group kills, output collection/spill, background handles, credential scrub) are inherited from [`dsh-bash-local`](../bash-local/); runner selection lives in [`dsh-sandbox-local`](../../sandbox/sandbox-local/).

-Deny-only at the seam: a denial is a reported fact, and this executor never negotiates permissions itself — the approval question lives in the tool layer (`dsh-tool-bash`), which drives the override this package honors.
+The executor takes no sandbox configuration of its own: the default mode and workspace root come from `ctx.sandboxPolicy`, and the runner choice belongs to the `ctx.sandbox` provider. Its own config is the local executor's knobs verbatim; the generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-bash-sandbox) is the exhaustive source.

+A denied command is reported, not retried silently: the result carries `sandbox: { mode, denied: true }` and the model-facing tool appends the denial marker.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design of the executor and points at the code that realizes it; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The executor is the sandboxing Service Provider for the `ctx.shell` seam: it inherits `dsh-bash-local`'s process mechanics and re-wraps each command's exact `['bash', '-c', command]` argv through `ctx.sandbox.confine()`, spawning the returned argv directly. Which platform runner confines the command — and whether one is usable at all — is the provider's concern; this package owns the bash side only: the selected mode, enforcement completeness, and denial classification on results.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `SandboxBashExecutor`, per-process fact retention, run/start wrapping |
+| [`src/helpers.ts`](src/helpers.ts) | Denial, runner-failure, and runner-spawn-failure classification |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; classification is observable in results) |
+| `tests/` | Exercised behavior across the bwrap, Landlock, and Seatbelt runners |
+
+### Main flow
+
+For a confined mode, `resolve()` stamps the per-call policy (the session's mode override, or the deployment fallback); `run` and `start` wrap the bash argv through the provider and hand the confined argv to the inherited subprocess path. At settlement the executor classifies the outcome: a runner failure outranks a denial because the command never ran, a failed run whose stderr carries the backend's denial dialect is reported `denied: true`, and every confined run carries its mode and enforcement facts. `danger-full-access` bypasses the provider entirely and stamps `denied: false`.
+
+### Invariants
+
+- **Fail closed** — a confined mode with no usable runner throws `SANDBOX_UNAVAILABLE`; unconfined passthrough never happens for a confined policy.
+- **Deny-only at the seam** — this executor never grants permission; the approval flow lives in the tool layer.
+- **Per-process facts** — confinement facts are retained per handle until settlement, because a provider may vary enforcement between overlapping calls.
+- **File effects only** — the mode vocabulary claims only file effects.

+
+These limits define when this executor is not a general security boundary. They are current package constraints, not a roadmap.

 - **Confinement covers file effects only** — network restriction and a uniform process-visibility guarantee are absent, so the modes are not a general-purpose security sandbox.
 - **Denials are inferred from failed-command stderr** — backend signatures make the inference portable, but a matching application error can be classified as a denial and a denial omitted from the retained tail can be missed.

-这是使用沙箱能力的 [`@deepseek-ai/dsh-shell`](../shell/) 执行器 seam 的 Service Provider。加载它时，应**用它替代** `@deepseek-ai/dsh-bash-local`，并同时加载 [`ctx.sandbox`](../../sandbox/sandbox/) 提供方（例如 [`@deepseek-ai/dsh-sandbox-local`](../../sandbox/sandbox-local/)）及 [`ctx.sandboxPolicy`](../../sandbox/sandbox-policy/)；默认模式和工作区根目录由后者负责，并与受沙箱约束的文件系统共享这些设置。无需使用替代工具插件；`dsh-tool-bash` 会检测执行器的 `sandboxMode` 能力并添加升权字段。
+## 概述
 
-包根目录导出默认与具名的 `SandboxBashExecutor` 插件及其 `Config`；结果分类 helper 保留在内部。
+`dsh-bash-sandbox` 是沙箱消费型 Bash 执行器：每条命令都以全新的 `bash -c` 进程运行，经 `ctx.sandbox` 能力隔离，而不是以 harness 进程的完整文件权限运行。每个已结算的结果都携带命令运行时的模式、沙箱是否拒绝了文件操作，以及所选 runner 对请求模式的强制执行完整度。当没有 runner 能强制执行受限模式时，调用按失败关闭原则抛结构化 `SANDBOX_UNAVAILABLE` 错误，绝不无隔离地运行。它是 `dsh-bash-local` 的受限兄弟包——共享其进程机制——工具层的升权字段也只在挂载它时才出现。
 
-每条命令的限制方式都是：把本执行器即将 spawn 的精确 `['bash', '-c', command]` argv 交给提供方，并直接 spawn 返回的 argv。使用随附的原生 runner 时，内层 Bash 保留 shell 语义，并且只在 runner 建立约束后才求值 `BASH_ENV`。由哪种平台 runner 执行限制，以及是否有 runner 可用，属于提供方职责；若无可用 runner，则按失败关闭原则拒绝执行并返回结构化 `SANDBOX_UNAVAILABLE` 错误，绝不能静默地无约束运行。本包只负责 bash 侧。

+
+### 何时选择
+
+当部署需要为 Bash 命令提供文件级隔离时选择它：已配置的策略决定默认模式与工作区根目录，每个会话还可以通过工具的升权流程按调用使用不同模式。模式只约束文件影响——网络仍不受限制，进程可见性因后端而异。需要非隔离执行，或平台没有可用沙箱后端时，请改为挂载 `dsh-bash-local`。
+
+### 模式与文件影响
 
 | 模式 | 文件影响 |
 |---|---|
-| `read-only`（默认） | 任何位置都不可写（在 `/dev` 中只有 `/dev/null` 节点可写，因此 `>/dev/null` 仍可正常工作） |
-| `workspace-write` | 只能写入 `workspaceRoot` + `/tmp`（在 bwrap 下为临时目录，在 Landlock 下为宿主 `/tmp`，在 Seatbelt 下为 `/private/tmp` 加每用户临时目录） |
-| `danger-full-access` | 不作限制；绝不咨询提供方。前台结果携带 `sandbox: { mode, denied: false }`；后台进程句柄不携带沙箱事实。 |

+### 最小配置
 
-- **拒绝是结果事实。** 如果一次失败运行的 stderr 包含所选后端自身的拒绝方言，即提供方在每次包装时加上的特征（bwrap 下的 EROFS 文本、Landlock 下的 EACCES、Seatbelt 下的 EPERM），则结果报告 `ShellRunResult.sandbox.denied: true`（从已收集的 stderr 尾部进行保守分类）。每次受限制运行还会携带执行时模式（`result.sandbox.mode`）与提供方强制执行完整性（`result.sandbox.enforcement`：`full`，或在较旧 Landlock ABI 上为 `partial`）。
-- **Runner 路径或 syscall 必须匹配。** 进程启动前，调用方拥有的 workdir 必须经独立验证可用，Node 必须报告 `ENOENT` 或 `EACCES`，并且错误必须符合以下一种形态：`error.path` 等于提供方返回的 `argv[0]`，同时 `syscall` 为 `'spawn'` 或精确的 `'spawn <runner>'`；或者 `error.path` 不存在，同时 `syscall` 为精确的 `'spawn <runner>'`。这样可以识别缺失的 runner、不可执行的 runner，或 shebang 解释器不可用的可执行脚本。没有精确错误路径的裸 `syscall: 'spawn'`、任何其他错误码、无效或不可用的 workdir、资源失败、无关 syscall 或无结构拒绝仍保留本地执行器的命令启动失败语义。前台执行会抛出 `SANDBOX_UNAVAILABLE` 并附带原始 spawn 错误详情，异步后台结算则会标记 `runnerFailed: true` 和 `denied: false`。如果 `SubprocessRuntime` 同步抛出同样能指明 runner 的 `ENOENT`／`EACCES` 形态，后台启动会抛出 `SANDBOX_UNAVAILABLE`；其他同步错误原样传播。进程启动后，先按整行精确匹配排除信息性行，随后规则的可选退出码检查和余下 stderr 中的一行致命诊断必须同时匹配。匹配结果优先于拒绝；前台执行会抛出 `SANDBOX_UNAVAILABLE` 并附带匹配到的致命行，已结算的后台进程则会标记 `process.sandbox.runnerFailed`，Bash 结果生成方通过通用 `job_output` 渲染它。无论走哪条路径，受限制的后台句柄都会保留自身的模式／强制执行事实，并释放每进程计数。
-- **部署回退，每次调用策略。** [`ctx.sandboxPolicy`](../../sandbox/sandbox-policy/) 为每次工具调用解析完整的 `SandboxExecutionPolicy`：调用会话提供自身的模式覆盖与不可变 cwd 根目录，部署配置则为无 agent（智能体）调用提供回退。已批准的升权只更改该策略的模式，会话根目录仍然附着其上。`resolve()` 把策略带入 spec，因此来自不同项目的重叠命令会在各自的根目录与模式下运行、分类和报告。能力事实 `ctx.shell.sandboxMode` 报告已配置的默认值，因此工具层只在装载该执行器时才公布升权；静态 bash 工具描述则单独负责拒绝与升权引导。
-- **只限制文件影响。** 模式词汇只声称文件影响。网络仍不受限制；进程可见性因后端而异，具体见 [`dsh-sandbox-local`](../../sandbox/sandbox-local/)。
-- 进程机制（spawn、进程组终止、输出收集／spill、后台句柄、凭证清理）继承自 [`dsh-bash-local`](../bash-local/)；runner 选择位于 [`dsh-sandbox-local`](../../sandbox/sandbox-local/)。

+<summary>实现细节——点击展开</summary>
+
+本节解释执行器的设计并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计概念
+
+本执行器是 `ctx.shell` seam 的沙箱 Service Provider：它继承 `dsh-bash-local` 的进程机制，把每条命令的精确 `['bash', '-c', command]` argv 经 `ctx.sandbox.confine()` 重新包装，并直接 spawn 返回的 argv。由哪种平台 runner 限制命令、以及是否有 runner 可用，属于提供方职责；本包只负责 bash 侧：所选模式、强制执行完整度，以及结果上的拒绝分类。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：`SandboxBashExecutor`、按进程保留事实、run/start 包装 |
+| [`src/helpers.ts`](src/helpers.ts) | 拒绝、runner 失败与 runner spawn 失败分类 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；分类在结果中可观察） |
+| `tests/` | 跨 bwrap、Landlock 与 Seatbelt runner 演练的行为 |
+
+### 主要流程
+
+对受限模式，`resolve()` 标记每次调用的策略（会话的模式覆盖值，或部署回退）；`run` 与 `start` 把 bash argv 经提供方包装，再把受限 argv 交给继承的 subprocess 路径。结算时执行器对结果分类：runner 失败优先于拒绝（命令从未运行），stderr 携带后端拒绝方言的失败运行报告 `denied: true`，每次受限运行都携带模式与强制执行事实。`danger-full-access` 完全绕过提供方，并标记 `denied: false`。
+
+### 不变式
+
+- **失败关闭**——受限模式没有可用 runner 时抛 `SANDBOX_UNAVAILABLE`；受限策略绝不会出现无隔离直通。
+- **seam 只报告拒绝**——本执行器从不授予权限；批准流程位于工具层。
+- **按进程保留事实**——隔离事实在结算前按句柄保留，因为提供方可能在重叠调用之间改变强制执行方式。
+- **只约束文件影响**——模式词汇只声称文件影响。

 # @deepseek-ai/dsh-pwsh-local
 
 English | [中文](README.zh.md)
 
-Local PowerShell Service Provider for the `@deepseek-ai/dsh-shell` executor seam over the [`@deepseek-ai/dsh-subprocess`](../../subprocess/subprocess/README.md) service: `PwshLocalExecutor` spawns `pwsh -NoLogo -NoProfile -NonInteractive -Command <command>` per call as a managed process through `ctx.subprocess`, and owns everything PowerShell-shaped — executable resolution, command defaulting and caps, timeout/cancel classification, the model-friendly terminal environment, and the model-facing stdout/stderr merge for background reads. Group mechanics (bounded spill-backed output, credential scrub, kill escalation, disposal) are the subprocess service's.
+## Summary
 
-The command string rides as ONE argv element to `-Command`: PowerShell itself parses the text, and no intermediate shell exists, so there is no shell-quoting layer to escape (the `bash -c` string domain has no equivalent here). Native Win32 paths (`C:\...`) pass through unchanged.
+`dsh-pwsh-local` is the PowerShell executor: every command runs as a fresh, non-interactive `pwsh -Command` process with no profile files, so no shell state survives between calls. It mirrors `dsh-bash-local`'s semantics call-for-call and adds PowerShell-shaped concerns: executable resolution, UTF-8 output pinning, and the model-friendly terminal environment. Commands run with the harness process's own authority — this executor confines nothing; compose `dsh-pwsh-sandbox` when commands need the sandbox capability. The model-facing `pwsh` tool talks to it once it is mounted.
 
-The package root exports the default and named `PwshLocalExecutor` plugin, its `Config`, the pure `resolvePwshPath`/`candidatePwshPaths` helpers, and the `ENV_OVERRIDES`/`ENCODING_PREAMBLE` constants the executor injects into every spawn.

+## Use this package
+
+Mount this executor when a composition needs PowerShell command execution — typically on Windows — without confinement. It registers as `ctx.shell`, and the model-facing `pwsh` tool works over it immediately: an agent calls the tool, and the command runs as a fresh `pwsh -Command` process with the budgets below.
+
+### When to choose it
+
+It is the Windows counterpart of `dsh-bash-local`: choose it where `pwsh` is the platform shell, so a composition can swap the POSIX rows for the pwsh rows and keep the same semantics. The executor resolves the `pwsh` executable from an explicit `pwshPath`, well-known Windows install locations, PATH entries, or Windows PowerShell 5.1 as a last resort. For unconfined execution it is the default; compose `dsh-pwsh-sandbox` when commands need the sandbox capability.
+
+### Minimal configuration
+
+Load the executor with the budgets you want; every field has a default, so the smallest composition is the plugin entry alone. The settings provider (when composed) layers a user section over this entry, so budgets can change at runtime without a reload (see [Adjusting budgets at runtime](#adjusting-budgets-at-runtime)).
 
 ```yaml
 - id: bash
   name: '@deepseek-ai/dsh-pwsh-local'
   config:
-    cwd: C:\path\to\workspace   # default: process.cwd()
-    timeoutMs: 120000           # default foreground timeout
-    maxTimeoutMs: 600000        # cap for per-call overrides
-    maxOutputBytes: 64000       # per-stream in-memory cap; overflow spills to disk
-    maxSpillBytes: 67108864     # per-stream full-output spill cap
-    graceMs: 3000               # kill escalation and post-exit pipe-drain grace
-    pwshPath: C:\Program Files\PowerShell\7\pwsh.exe  # explicit executable; else well-known locations, then PATH
+    cwd: C:\path\to\workspace
+    timeoutMs: 120000
 ```
 
-## Behavior
+| Field | Default | Meaning |
+|---|---|---|
+| `cwd` | `process.cwd()` | Default working directory for commands |
+| `timeoutMs` | `120,000` | Default foreground timeout, in milliseconds |
+| `maxTimeoutMs` | `600,000` | Cap for per-call timeout overrides |
+| `maxOutputBytes` | `64,000` | Per-stream in-memory output cap; overflow spills to a temp file |
+| `maxSpillBytes` | `67,108,864` | Per-stream full-output spill cap |
+| `graceMs` | `3,000` | Grace period for kill escalation and post-exit pipe draining |
+| `pwshPath` | resolved | Explicit pwsh executable; else well-known locations, then PATH |
 
-The Windows counterpart of `dsh-bash-local`, deliberately mirroring its semantics call-for-call:
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-pwsh-local) is the exhaustive source for every accepted field and its JSDoc.
 
-- **Spawn per call, no shell state** — every call is a fresh non-interactive `pwsh -Command` (deterministic; no profile files). The `-NoLogo -NoProfile -NonInteractive` flags disable startup banners, profile loading, and prompts that would garble tool output.
-- **The composition entry is a layer, not the last word** — when a settings provider is composed, this executor registers the capability's [`bash` namespace](../shell/README.md) with the entry above as its base, so a user section in `settings.yaml` layers over it and the next command runs with the new budgets. The namespace is shared with the POSIX family because a host composes exactly one provider of `ctx.shell`; a document written on either platform keeps resolving on the other. Values the schema cannot judge (positive and finite, the `graceMs` timer bound) are refused at the write, leaving the running executor on its last good section.
-- **UTF-8 output pinned** — every command runs with `[Console]::OutputEncoding` and `$OutputEncoding` set to UTF-8 first, so the Windows PowerShell 5.1 fallback (or any host whose console code page is not UTF-8) cannot garble non-ASCII output: the subprocess collector decodes bytes as UTF-8. Input encoding is left at the host default; pwsh 7 defaults to UTF-8 and is unaffected.
-- **Executable resolution** — `resolvePwshPath` prefers an explicit `pwshPath`, then on Windows probes PowerShell 7's install location, every PATH entry (Microsoft Store installs; surrounding quotes stripped), and Windows PowerShell 5.1 as a legacy last resort, checking each candidate with an lstat probe that accepts a real file or a link-shaped reparse point (a Store app execution alias stat-fails against its target's ACL, but lstat sees the alias itself); elsewhere it falls back to a bare `pwsh` resolved through PATH. Resolution is a pure function of `(configured, env, platform)`; it runs at construction and again only when a stored `pwshPath` differs from the one the current executable was resolved from, so an unrelated settings change never re-probes the filesystem.
-- **Configured budgets over managed groups** — `resolve()` fills `workdir`/`timeoutMs`/`stdoutMaxBytes` from config, and every spawn hands the service explicit byte caps, spill cap, and `graceMs`. The grace must be positive, finite, and no greater than [`MAX_TIMER_DELAY_MS`](../../util/timeout/README.md), so Node can represent it with one timer. Tree termination (taskkill on Windows, process-group signals on POSIX), the post-exit pipe-drain grace, tail-keep truncation, and bounded spill files are [`dsh-subprocess-local`](../../subprocess/subprocess-local/README.md) mechanics. A foreground `ShellExecRequest.stdoutMaxBytes` can raise stdout's capture budget for one trusted caller; stderr and background runs still use `maxOutputBytes`.
-- **Timeout and cancel classification** — `run()` fuses its config-clamped timeout with the caller's signal through one deadline; only the executor's own timeout reports `timedOut`, an upstream cancel reports `aborted`, and a self-terminated command reports neither ([timeout-library Agent Note](../../../.agents/notes/implemented/architecture/2026-07-06-timeout-deadline-library.md)). Windows reports forced termination as exit 1 without a signal, so signal-stamped facts (`signal`, `killed` status) are POSIX-only there; the timeout/abort classification is platform-independent.
-- **Model-friendly terminal env** — `NO_COLOR=1 PAGER=cat GIT_PAGER=cat` (no `TERM=dumb`: that is a POSIX concept; `NO_COLOR` is honored by modern PowerShell renderers) merged as ordinary env under the service's credential scrub and `DSH_*` channel rules; an explicit caller entry still wins.
-- **Background processes** — `start()` returns a live `ShellProcess` handle immediately, no timeout applies, and the handle's `readOutput()` merges the service's offset-based stdout/stderr reads into one marked-section delta with a consuming cursor. A still-running process belongs to the subprocess service, so it survives executor reloads and dies (killed and joined) with the service's disposal. Everything task-shaped (ids, ownership, polling, notices) lives in the generic [`ctx.jobs` runtime](../../jobs/jobs/README.md), which the tool layer registers the handle with — this executor never sees a session or a registry.
+### Running commands
 
+Run a command with `run` and read its output from the result; a nonzero exit, a timeout, or a cancellation resolves descriptively, and only infrastructure failures reject. The command string rides as one argument to `-Command`: PowerShell parses the text itself and no intermediate shell exists, so there is no shell-quoting layer to escape and native Win32 paths pass through unchanged. Every command pins UTF-8 output first, so non-ASCII output is not garbled even on the Windows PowerShell 5.1 fallback. The environment is model-friendly: `NO_COLOR=1 PAGER=cat GIT_PAGER=cat` (no `TERM=dumb` — a POSIX concept), with explicit caller-provided entries still winning.
+
+```text
+const result = await ctx.shell.run(ctx.shell.resolve({ command: 'Get-ChildItem' }))
+if (result.timedOut) console.log('timed out after', result.timeoutMs)
+```
+
+### Background processes
+
+Call `start` to run a command in the background; it returns a handle immediately and no timeout applies. `readOutput()` merges the stream deltas into one consuming read, marking stderr under a `[stderr]` section; `kill()` stops the process tree; `done` settles when the process closes and never rejects. Job ids, ownership, polling, and notices belong to the generic `ctx.jobs` runtime, which the tool layer registers the handle with.
+
+<a id="adjusting-budgets-at-runtime"></a>
+### Adjusting budgets at runtime
+
+When a settings provider is composed, this executor registers the capability's shared `shell` settings namespace — the same one the POSIX family uses, because a host composes exactly one provider of `ctx.shell` — so a user section in `settings.yaml` layers over the composition entry and the next command runs with the new budgets. Values the schema cannot judge — positive and finite numbers, and the `graceMs` timer bound — are refused at the write, leaving the running executor on its last good section.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design of the executor and points at the code that realizes it; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The executor is the PowerShell Service Provider for the `ctx.shell` seam built on the subprocess capability: it owns everything pwsh-shaped — executable resolution, command defaulting and caps, deadline fusion and cause classification, UTF-8 output pinning, the model-friendly terminal environment, and the background read merge — while process-tree mechanics (bounded spill-backed output, credential scrub, kill escalation, disposal) belong to the subprocess service. Every call spawns a fresh non-interactive `pwsh -Command` with `-NoLogo -NoProfile -NonInteractive`, so commands are deterministic and profile state never leaks between calls.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `PwshLocalExecutor`, `Config`, settings wiring, argv seam |
+| [`src/resolve.ts`](src/resolve.ts) | Pure `resolvePwshPath`/`candidatePwshPaths` executable resolution |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; contracts are enforced at the owning seam) |
+| `tests/` | Exercised behavior: budgets, classification, resolution, background handles |
+
+### Main flow
+
+A call runs through three steps: `resolve()` fills `workdir`/`timeoutMs`/`stdoutMaxBytes` from config (capping the per-call `timeoutMs` override); the executor builds the pwsh argv — `pwsh -NoLogo -NoProfile -NonInteractive -Command <encoding preamble + command>` — fuses the config-clamped timeout with the caller's abort signal into one deadline, and spawns through `ctx.subprocess` with explicit byte caps and the `graceMs`; the settled outcome is classified and projected into a `ShellRunResult`. Windows reports forced termination as exit 1 without a signal, so signal-stamped facts are POSIX-only there; the timeout/abort classification is platform-independent.
+
+### Invariants and ownership
+
+- The `graceMs` budget must be positive, finite, and no greater than `MAX_TIMER_DELAY_MS` so Node can represent it with one timer; invalid values are refused where they are written.
+- Environment layering is fixed: terminal overrides first, then the caller's `env`, then the trusted `dshEnv` snapshot last; the subprocess service scrubs ambient credentials and inherited `DSH_*` names independently.
+- Executable resolution is a pure function of `(configured, env, platform)` and re-probes the filesystem only when the stored `pwshPath` differs from the one the current executable was resolved from.
+- A background process belongs to the subprocess service: it survives an executor-only reload and is killed and joined when the service disposes.

+
+- **Unconfined by itself** — commands run with the harness process's authority; deployments needing confinement compose a sandboxing executor or policy instead.
 - **No persistent shell or PTY** — every call starts a fresh `pwsh -Command`.
 - **The command string is PowerShell text** — the `-Command` domain has no shell-quoting layer, but a model-facing command is parsed by PowerShell itself, so PowerShell syntax errors are command failures, not launch failures.
 - **A background spawn-failure note is single-delivery** — the subprocess service buffers no output for a process that never ran, so the executor injects `spawn failed: …` into exactly one `readOutput()` delta; a reader that discards that delta cannot recover it.
-- **Windows termination reports no signal** — a force-killed process settles as exit 1 with `signal: null`, so signal-based status classification (POSIX `killed`) does not apply on Windows; `kill()`-initiated stops still stamp `killed` directly.
-- **The encoding preamble precedes the command** — PowerShell requires `param(...)`, `#requires`, and `using namespace`/`using assembly` statements at the very top of a script, so a command whose first statement is one of those cannot run under the UTF-8 output preamble. Wrap a `param(...)` script in `& { … }` (a param block legally heads a script block); `using` statements and `#requires` have no in-command workaround (`#requires` is inert inside `-Command` regardless of position) — run such scripts from a file instead.
-- **Non-ASCII stdin under Windows PowerShell 5.1 may be mis-decoded** — the preamble pins output encoding only; `[Console]::InputEncoding` stays at the host default because setting it under redirected stdin throws. pwsh 7 defaults to UTF-8 and is unaffected.

-命令字符串作为单个 argv 元素传给 `-Command`：由 PowerShell 自己解析文本，不存在中间 shell，因此没有需要转义的 shell 引号层（这里不存在与 `bash -c` 字符串域对应的层）。原生 Win32 路径（`C:\...`）原样通过。
+`dsh-pwsh-local` 是 PowerShell 执行器：每条命令都以全新的非交互 `pwsh -Command` 进程运行，不加载 profile 文件，因此调用之间不会残留任何 shell 状态。它逐调用镜像 `dsh-bash-local` 的语义，并额外负责 PowerShell 层事项：可执行文件解析、UTF-8 输出固定与面向模型的终端环境。命令以 harness 进程自身的权限运行——本执行器不做任何隔离；需要沙箱能力时请组合 `dsh-pwsh-sandbox`。挂载后，面向模型的 `pwsh` 工具会与它对接。
 
-包根导出默认与具名 `PwshLocalExecutor` 插件、其 `Config`、纯函数 `resolvePwshPath`/`candidatePwshPaths` 辅助函数，以及执行器注入每次 spawn 的 `ENV_OVERRIDES`/`ENCODING_PREAMBLE` 常量。

+## 使用本包
+
+当组合需要执行 PowerShell 命令——通常是在 Windows 上——且不需要隔离时，挂载此执行器。它注册为 `ctx.shell`，面向模型的 `pwsh` 工具会立即基于它工作：agent 调用工具，命令即以全新 `pwsh -Command` 进程按下面的预算运行。
+
+### 何时选择
+
+它是 `dsh-bash-local` 的 Windows 对应实现：当 `pwsh` 是平台 shell 时选择它，组合即可把 POSIX 行换成 pwsh 行并保持相同的语义。执行器从显式 `pwshPath`、常见的 Windows 安装位置、PATH 条目，或作为最后手段的 Windows PowerShell 5.1 解析 `pwsh` 可执行文件。非隔离执行时它就是默认选择；需要沙箱能力时组合 `dsh-pwsh-sandbox`。
+
+### 最小配置
+
+按你需要的预算加载执行器；每个字段都有默认值，因此最小的组合就是单独一个插件条目。当组合了设置提供方时，用户段会叠加在该条目之上，预算无需重载即可在运行时变更（见[运行时调整预算](#adjusting-budgets-at-runtime)）。
 
 ```yaml
 - id: bash
   name: '@deepseek-ai/dsh-pwsh-local'
   config:
-    cwd: C:\path\to\workspace   # default: process.cwd()
-    timeoutMs: 120000           # default foreground timeout
-    maxTimeoutMs: 600000        # cap for per-call overrides
-    maxOutputBytes: 64000       # per-stream in-memory cap; overflow spills to disk
-    maxSpillBytes: 67108864     # per-stream full-output spill cap
-    graceMs: 3000               # kill escalation and post-exit pipe-drain grace
-    pwshPath: C:\Program Files\PowerShell\7\pwsh.exe  # explicit executable; else well-known locations, then PATH
+    cwd: C:\path\to\workspace
+    timeoutMs: 120000
 ```
 
-## 行为
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `cwd` | `process.cwd()` | 命令的默认工作目录 |
+| `timeoutMs` | `120,000` | 默认前台超时，单位为毫秒 |
+| `maxTimeoutMs` | `600,000` | 每次调用超时覆盖值的上限 |
+| `maxOutputBytes` | `64,000` | 每流内存输出上限；溢出后 spill 到临时文件 |
+| `maxSpillBytes` | `67,108,864` | 每流完整输出的 spill 上限 |
+| `graceMs` | `3,000` | 终止升级与退出后管道排空的宽限时间 |
+| `pwshPath` | 自动解析 | 显式 pwsh 可执行文件；否则依次探测常见位置，再查 PATH |
 
-这是 `dsh-bash-local` 的 Windows 对应实现，有意逐次调用保持语义一致：
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-pwsh-local)是每个受支持字段及其 JSDoc 的穷尽式真源。
 
-- **每次调用新建进程，无 shell 状态**——每次调用都是全新的非交互 `pwsh -Command`（确定性；不加载 profile 文件）。`-NoLogo -NoProfile -NonInteractive` 关闭启动横幅、profile 加载与会干扰工具输出的提示符。
-- **组装条目是一层，而不是最终值**——当组装中存在 settings 提供方时，本执行器以上面的条目为 base 注册该能力的 [`bash` 命名空间](../shell/README.zh.md)，因此 `settings.yaml` 中的用户段会叠加其上，下一条命令即按新预算运行。该命名空间与 POSIX 家族共用，因为一个宿主只组装一个 `ctx.shell` 提供方；在任一平台写下的文档在另一平台仍能解析。schema 无法判定的值（正有限、`graceMs` 的定时器上界）会在写入时被拒绝，运行中的执行器保持它最后一份可用的段。
-- **UTF-8 输出固定**——每条命令都先以 UTF-8 设置 `[Console]::OutputEncoding` 与 `$OutputEncoding`，因此 Windows PowerShell 5.1 兜底（或任何控制台代码页非 UTF-8 的主机）不会破坏非 ASCII 输出：subprocess 收集器以 UTF-8 解码字节。输入编码保持宿主默认；pwsh 7 默认为 UTF-8，不受影响。
-- **可执行文件解析**——`resolvePwshPath` 优先显式 `pwshPath`，然后在 Windows 上依次探测 PowerShell 7 安装位置、每个 PATH 条目（Microsoft Store 安装；剥离两端引号）以及作为遗留兜底的 Windows PowerShell 5.1，逐一用 lstat 探测检查（接受真实文件或链接形态的重解析点：Store 的 app execution alias 对其目标 stat 会因 ACL 失败，但 lstat 能看到别名本身）；其他平台回退为通过 PATH 解析的裸 `pwsh`。解析是 `(configured, env, platform)` 的纯函数；它在构造时执行，此后仅当存储的 `pwshPath` 与当前可执行文件所依据的值不同才再次执行，因此无关的设置变更绝不会重新探测文件系统。
-- **受管进程组之上的配置预算**——`resolve()` 从配置填充 `workdir`/`timeoutMs`/`stdoutMaxBytes`，每次 spawn 都向服务提供显式字节上限、spill 上限与 `graceMs`。该宽限期须为正有限值，且不得大于 [`MAX_TIMER_DELAY_MS`](../../util/timeout/README.zh.md)，这样 Node 就能用一个定时器表示它。进程树终止（Windows 用 taskkill，POSIX 用进程组信号）、退出后管道排空宽限、保尾截断与有界 spill 文件是 [`dsh-subprocess-local`](../../subprocess/subprocess-local/README.zh.md) 的机制。前台 `ShellExecRequest.stdoutMaxBytes` 可为单个受信调用方提高 stdout 捕获预算；stderr 与后台运行仍使用 `maxOutputBytes`。
-- **超时与取消分类**——`run()` 通过一个 deadline 融合按配置上限截取的超时与调用方信号；只有执行器自身超时报告 `timedOut`，上游取消报告 `aborted`，自我终止的命令两者都不报告（见 [timeout 库 Agent Note](../../../.agents/notes/implemented/architecture/2026-07-06-timeout-deadline-library.zh.md)）。Windows 将强制终止报告为退出码 1 且无信号，因此带信号标记的事实（`signal`、`killed` 状态）在那里仅限 POSIX；超时/取消分类与平台无关。
-- **面向模型的终端环境**——`NO_COLOR=1 PAGER=cat GIT_PAGER=cat`（没有 `TERM=dumb`：那是 POSIX 概念；现代 PowerShell 渲染器遵循 `NO_COLOR`），作为普通 env 在服务的凭据清理与 `DSH_*` 通道规则之下合并；显式调用方条目仍然优先。
-- **后台进程**——`start()` 立即返回存活的 `ShellProcess` 句柄，不设超时；句柄的 `readOutput()` 把服务基于偏移的 stdout/stderr 读取合并为一条按分段标记、通过消费游标推进的增量。仍在运行的进程属于 subprocess 服务，因此它跨执行器重载存活，并随服务 dispose（被终止并 join）。一切任务相关职责（job id、所有权、轮询、通知）都在通用 [`ctx.jobs` 运行时](../../jobs/jobs/README.zh.md) 中，由工具层把句柄注册进去——本执行器从不接触会话或注册表。
+### 运行命令
 
+用 `run` 运行命令并从结果读取输出；非零退出、超时或取消都会描述性地 resolve，只有基础设施失败才 reject。命令字符串作为单个参数传给 `-Command`：由 PowerShell 自己解析文本，不存在中间 shell，因此没有需要转义的 shell 引号层，原生 Win32 路径也原样通过。每条命令都先固定 UTF-8 输出，因此即使在 Windows PowerShell 5.1 兜底上，非 ASCII 输出也不会乱码。环境默认面向模型：`NO_COLOR=1 PAGER=cat GIT_PAGER=cat`（没有 `TERM=dumb`——那是 POSIX 概念），调用方显式提供的条目仍然优先。
+
+```text
+const result = await ctx.shell.run(ctx.shell.resolve({ command: 'Get-ChildItem' }))
+if (result.timedOut) console.log('timed out after', result.timeoutMs)
+```
+
+### 后台进程
+
+调用 `start` 即可在后台运行命令；它立即返回句柄，且不应用任何超时。`readOutput()` 把流增量合并为一次消费式读取，并在 `[stderr]` 分段下标记 stderr；`kill()` 停止进程树；`done` 在进程关闭时结算且绝不 reject。job id、所有权、轮询与通知属于通用 `ctx.jobs` 运行时，工具层会把句柄注册进去。

+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释执行器的设计并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计概念
+
+本执行器是基于 subprocess 能力的 `ctx.shell` seam 的 PowerShell Service Provider：它负责所有 pwsh 层职责——可执行文件解析、命令默认化与上限、deadline 融合与原因分类、UTF-8 输出固定、面向模型的终端环境，以及后台读取合并——而进程树机制（有界 spill 输出、凭据清除、终止升级、dispose（资源释放））属于 subprocess 服务。每次调用都 spawn 全新的非交互 `pwsh -Command`，并带 `-NoLogo -NoProfile -NonInteractive`，因此命令是确定性的，profile 状态绝不会在调用之间泄漏。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：`PwshLocalExecutor`、`Config`、设置接线、argv seam |
+| [`src/resolve.ts`](src/resolve.ts) | 纯函数 `resolvePwshPath`/`candidatePwshPaths` 可执行文件解析 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；约定在所属 seam 处执行） |
+| `tests/` | 已演练的行为：预算、分类、解析、后台句柄 |
+
+### 主要流程
+
+一次调用分三步：`resolve()` 从配置填充 `workdir`/`timeoutMs`/`stdoutMaxBytes`（并限制每次调用的 `timeoutMs` 覆盖值）；执行器构建 pwsh argv——`pwsh -NoLogo -NoProfile -NonInteractive -Command <编码 preamble + 命令>`——把按配置钳位的超时与调用方的中止信号融合为一个 deadline，再以显式字节上限与 `graceMs` 通过 `ctx.subprocess` spawn；结算的结果被分类并投影为 `ShellRunResult`。Windows 把强制终止报告为退出码 1 且无信号，因此带信号标记的事实在那里仅限 POSIX；超时/取消分类则与平台无关。
+
+### 不变式与归属
+
+- `graceMs` 预算必须为正有限值且不大于 `MAX_TIMER_DELAY_MS`，这样 Node 就能用一个定时器表示它；无效值在写入处被拒绝。
+- 环境分层固定：先是终端覆盖值，然后是调用方的 `env`，最后才是受信任的 `dshEnv` 快照；subprocess 服务独立清除环境中的凭据与继承的 `DSH_*` 名称。
+- 可执行文件解析是 `(configured, env, platform)` 的纯函数，仅当存储的 `pwshPath` 与当前可执行文件所依据的值不同时才重新探测文件系统。
+- 后台进程属于 subprocess 服务：它能在仅重载执行器后存活，并在服务 dispose 时被终止并 join。

+<a id="known-limitations-and-deferred-work"></a>
+
+
+这些限制说明本执行器何时不合适。它们是当前包约束，不是路线图。
+
+- **自身不提供隔离**——命令以 harness 进程的权限运行；需要隔离的部署组合沙箱执行器或策略。
+- **没有持久 shell 或 PTY**——每次调用都启动全新的 `pwsh -Command`。
 - **命令字符串是 PowerShell 文本**——`-Command` 域没有 shell 引号层，但面向模型的命令由 PowerShell 自己解析，因此 PowerShell 语法错误是命令失败，而非启动失败。
-- **后台 spawn 失败提示只投递一次**——subprocess 服务不会为从未运行的进程缓冲输出，因此执行器只把 `spawn failed: …` 注入一次 `readOutput()` 增量；丢弃该增量的读取方无法恢复它。
-- **Windows 终止不报告信号**——被强制终止的进程以退出码 1、`signal: null` 结束，因此基于信号的状态分类（POSIX `killed`）在 Windows 上不适用；`kill()` 发起的停止仍会直接标记为 `killed`。
-- **编码 preamble 位于命令之前**——PowerShell 要求 `param(...)`、`#requires` 与 `using namespace`/`using assembly` 语句位于脚本最顶部，因此以其中一种开头的命令无法在 UTF-8 输出 preamble 下运行。`param(...)` 脚本可包进 `& { … }`（param 块可以合法地位于脚本块开头）；`using` 语句与 `#requires` 在命令内没有变通办法（`#requires` 在 `-Command` 中无论位置如何都不生效）——此类脚本请改从文件运行。
-- **Windows PowerShell 5.1 下的非 ASCII stdin 可能被错误解码**——preamble 只固定输出编码；`[Console]::InputEncoding` 保持主机默认，因为在重定向 stdin 下设置它会抛出异常。pwsh 7 默认 UTF-8，不受影响。
+- **后台 spawn 失败提示只交付一次**——subprocess 服务不会为从未真正运行的进程缓冲任何输出，因此执行器把 `spawn failed: …` 注入恰好一个 `readOutput()` 增量；丢弃了该增量的读取方无法再恢复它。
+- **Windows 终止不报告信号**——被强制终止的进程以退出码 1、`signal: null` 结算，因此基于信号的状态分类在 Windows 上不适用；`kill()` 发起的停止仍会直接标记为 `killed`。
+- **编码 preamble 位于命令之前**——PowerShell 要求 `param(...)`、`#requires` 与 `using` 语句位于脚本最顶部，因此以其中一种开头的命令无法在 UTF-8 输出 preamble 下运行；`param(...)` 脚本请包进 `& { … }`，`using`/`#requires` 脚本请改从文件运行。
+- **Windows PowerShell 5.1 下的非 ASCII stdin 可能被错误解码**——preamble 只固定输出编码；`[Console]::InputEncoding` 保持主机默认，因为在重定向 stdin 下设置它会抛出异常；pwsh 7 默认 UTF-8，不受影响。

 # @deepseek-ai/dsh-pwsh-sandbox
 
 English | [中文](README.zh.md)
 
-Sandbox-consuming PowerShell implementation of the [`ctx.shell` executor seam](../shell/): every command runs as `pwsh -NoLogo -NoProfile -NonInteractive -Command <command>` **confined through `ctx.sandbox`**, with the selected mode, enforcement, and denial facts stamped on each settled result. The pwsh twin of [`@deepseek-ai/dsh-bash-sandbox`](../bash-sandbox/), a call-for-call mirror per the [pwsh executor and tool decision](../../../.agents/notes/implemented/feature/2026-08-01-pwsh-tool-and-executor.md) — the confinement substance is platform-neutral: on Windows the sandbox seam resolves to the ACL restricted-token runner chain ([`@deepseek-ai/dsh-sandbox-windows-acl`](../../sandbox/sandbox-windows-acl/)), on Linux/macOS to bwrap/Landlock/Seatbelt.
+## Summary
 
-The executor inherits [`@deepseek-ai/dsh-pwsh-local`](../pwsh-local/)'s process mechanics and consumes its argv-level seam (`argv()` / `runArgv()` / `startArgv()` / `onProcessDone()`) to wrap the exact pwsh invocation through the provider. The sandbox policy (mode + workspace root) is NOT this package's config: it rides each call from `ctx.sandboxPolicy` (tool calls pass the calling session's resolved policy; direct calls fall back to deployment policy).
+`dsh-pwsh-sandbox` is the sandbox-consuming PowerShell executor: every command runs as a fresh `pwsh -Command` process confined through the `ctx.sandbox` capability, with the selected mode, enforcement, and denial facts stamped on each settled result. On Windows the sandbox seam resolves to the ACL restricted-token runner chain; on Linux and macOS it uses bwrap, Landlock, or Seatbelt. When no runner can enforce a confined mode, the call fails closed with a structured `SANDBOX_UNAVAILABLE` error rather than running unconfined. It is the pwsh twin of `dsh-bash-sandbox`, mirroring it call-for-call.
 
-## Behavior
+## Table of Contents
 
-- `danger-full-access`: commands run through the local executor unchanged; results carry `sandbox: { mode, denied: false }`.
-- Confined modes (`read-only`, `workspace-write`): the pwsh argv is wrapped by `ctx.sandbox.confine()`; runner-launch refusal fails closed with `SANDBOX_UNAVAILABLE` (foreground throw, background `runnerFailed` fact), and a denied write classifies against the selected backend's `denialSignatures` into `sandbox.denied`.

+<a id="use-this-package"></a>
+## Use this package
+
+Mount this executor instead of `dsh-pwsh-local` when PowerShell commands must not run with the harness process's full file authority. It registers as `ctx.shell`, inherits `dsh-pwsh-local`'s process mechanics, and requires a `ctx.sandbox` provider plus `ctx.sandboxPolicy`.
+
+### When to choose it
+
+Choose it when a deployment needs file-level confinement for PowerShell commands, typically on Windows. The confinement substance is platform-neutral: the sandbox seam picks the platform's runner — the ACL restricted-token chain on Windows, bwrap/Landlock/Seatbelt elsewhere — while this executor owns the pwsh side. The sandbox policy (mode plus workspace root) is not this package's config: it rides each call from `ctx.sandboxPolicy`, with tool calls passing the calling session's resolved policy and direct calls falling back to deployment policy.
+
+### Modes and file effects
+
+| Mode | File effects |
+|---|---|
+| `read-only` (default) | Writes are denied; the boundary stays partial because the restricted token retains Everyone |
+| `workspace-write` | Writes under the policy's workspace root plus a private temp directory; `TMP`/`TEMP` are rewritten to it before spawning |
+| `danger-full-access` | No confinement; the provider is never consulted, and results carry `sandbox: { mode, denied: false }` |
+
+### Minimal configuration
+
+On Windows, mount the ACL restricted-token provider; on Linux and macOS, mount the local runner provider instead. The executor's own config is the local pwsh executor's knobs verbatim; the generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-pwsh-sandbox) is the exhaustive source.
+
+```yaml
+- id: sandbox
+  name: '@deepseek-ai/dsh-sandbox-windows-acl'
+- id: sandbox-policy
+  name: '@deepseek-ai/dsh-sandbox-policy'
+  config:
+    mode: read-only
+    workspaceRoot: !!js process.cwd() # fallback for calls without a session cwd
+- id: bash
+  name: '@deepseek-ai/dsh-pwsh-sandbox'
+```
+
+### Denials and escalation
+
+A denied command is reported as a fact: the result carries `sandbox: { mode, denied: true }`, and the tool layer converts it into the standard permission-denied surface — the same one the bash tool uses. When escalation is available, the model may retry the exact command once with the narrowest wider mode and a one-sentence justification; the approval prompt asks the user, and nothing executes before approval. This executor never negotiates permissions itself.
+
+### Failures and recovery
+
+If no runner can enforce a confined mode, the foreground call fails with `SANDBOX_UNAVAILABLE` and a background process records a runner-failure fact — never a silent unconfined run. A runner-attributable spawn failure carries the original spawn error as detail; other spawn rejections keep the local executor's ordinary command-start semantics.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design of the executor and points at the code that realizes it; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The executor is the pwsh twin of `dsh-bash-sandbox`: it inherits `dsh-pwsh-local`'s process mechanics, consumes its argv-level seam (`argv()`/`runArgv()`/`startArgv()`/`onProcessDone()`), and wraps the exact pwsh invocation through `ctx.sandbox.confine()` before spawning. The confinement substance is platform-neutral — the sandbox seam resolves to the platform's runner — while this package owns the pwsh side only: the selected mode, enforcement completeness, and denial classification on results.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `SandboxPwshExecutor`, per-process fact retention, run/start wrapping |
+| [`src/helpers.ts`](src/helpers.ts) | Denial, runner-failure, and runner-spawn-failure classification |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; classification is observable in results) |
+| `tests/` | Exercised behavior across the ACL and platform runners |
+
+### Main flow
+
+For a confined mode, `resolve()` stamps the per-call policy; `run` and `start` wrap the pwsh argv through the provider and hand the confined argv to the inherited subprocess path. At settlement the executor classifies the outcome: a runner failure outranks a denial because the command never ran, a failed run whose stderr carries the runner's denial dialect is reported `denied: true`, and every confined run carries its mode and enforcement facts. `danger-full-access` bypasses the provider entirely and stamps `denied: false`.
+
+### Invariants
+
+- **Fail closed** — a confined mode with no usable runner throws `SANDBOX_UNAVAILABLE`; unconfined passthrough never happens for a confined policy.
+- **Deny-only at the seam** — this executor never grants permission; the approval flow lives in the tool layer.
+- **Per-process facts** — confinement facts are retained per handle until settlement, because a provider may vary enforcement between overlapping calls.

 ## Model Experience
 
 ### Confinement works, denial surfaces as command failure

-沙盒消费型的 [`ctx.shell` 执行器 seam](../shell/) 的 PowerShell 实现：每条命令以 `pwsh -NoLogo -NoProfile -NonInteractive -Command <command>` 运行，**经 `ctx.sandbox` 隔离**，选定模式、强制完整性、拒绝事实都盖在每次结算的结果上。它是 [`@deepseek-ai/dsh-bash-sandbox`](../bash-sandbox/) 的 pwsh 孪生，按 [pwsh 执行器与工具决策](../../../.agents/notes/implemented/feature/2026-08-01-pwsh-tool-and-executor.zh.md) 逐调用镜像——隔离实体本身是平台无关的：Windows 上沙盒 seam 解析到 ACL 受限令牌 runner 链（[`@deepseek-ai/dsh-sandbox-windows-acl`](../../sandbox/sandbox-windows-acl/)），Linux/macOS 上解析到 bwrap/Landlock/Seatbelt。
+## 概述
 
-执行器继承 [`@deepseek-ai/dsh-pwsh-local`](../pwsh-local/) 的进程机制，并消费其 argv 级 seam（`argv()` / `runArgv()` / `startArgv()` / `onProcessDone()`）把精确的 pwsh 调用经 provider 包装。沙盒策略（模式 + 工作区根目录）不是本包的配置：每次调用由 `ctx.sandboxPolicy` 随行（工具层传调用会话解析后的策略；直接调用回退到部署策略）。
+`dsh-pwsh-sandbox` 是沙箱消费型 PowerShell 执行器：每条命令都以全新的 `pwsh -Command` 进程运行，经 `ctx.sandbox` 能力隔离，并在每个已结算的结果上标记所选模式、强制执行完整度与拒绝事实。在 Windows 上，sandbox seam 解析到 ACL 受限令牌 runner 链；在 Linux 与 macOS 上则使用 bwrap、Landlock 或 Seatbelt。当没有 runner 能强制执行受限模式时，调用按失败关闭原则抛结构化 `SANDBOX_UNAVAILABLE` 错误，绝不无隔离地运行。它是 `dsh-bash-sandbox` 的 pwsh 孪生，逐调用镜像。

+## 使用本包
+
+当 PowerShell 命令不得以 harness 进程的完整文件权限运行时，用本执行器替代 `dsh-pwsh-local`。它注册为 `ctx.shell`，继承 `dsh-pwsh-local` 的进程机制，并要求一个 `ctx.sandbox` 提供方加上 `ctx.sandboxPolicy`。
+
+### 何时选择
+
+当部署需要为 PowerShell 命令提供文件级隔离时选择它，通常是在 Windows 上。隔离实体本身是平台无关的：sandbox seam 选择平台的 runner——Windows 上是 ACL 受限令牌链，其他平台是 bwrap/Landlock/Seatbelt——而本执行器只负责 pwsh 侧。沙箱策略（模式加工作区根目录）不是本包的配置：它随每次调用从 `ctx.sandboxPolicy` 而来，工具调用传调用会话解析后的策略，直接调用回退到部署策略。
+
+### 模式与文件影响
+
+| 模式 | 文件影响 |
+|---|---|
+| `read-only`（默认） | 写入被拒绝；由于受限令牌必须保留 Everyone，边界仍是不完整的 |
+| `workspace-write` | 只能写入策略的工作区根目录加一个私有临时目录；spawn 前 `TMP`/`TEMP` 会被重写到该目录 |
+| `danger-full-access` | 不作限制；绝不咨询提供方，结果携带 `sandbox: { mode, denied: false }` |
+
+### 最小配置
+
+在 Windows 上挂载 ACL 受限令牌提供方；在 Linux 与 macOS 上则改挂本地 runner 提供方。执行器自身的配置就是本地 pwsh 执行器的旋钮，逐字继承；生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-pwsh-sandbox)是穷尽式真源。
+
+```yaml

+  name: '@deepseek-ai/dsh-sandbox-windows-acl'
+- id: sandbox-policy
+  name: '@deepseek-ai/dsh-sandbox-policy'
+  config:
+    mode: read-only
+    workspaceRoot: !!js process.cwd() # fallback for calls without a session cwd
+- id: bash
+  name: '@deepseek-ai/dsh-pwsh-sandbox'
+```
+
+### 拒绝与升权
+
+被拒绝的命令作为事实被报告：结果携带 `sandbox: { mode, denied: true }`，工具层把它转成标准的权限拒绝面——与 bash 工具使用同一个。当升权可用时，模型可以用最窄的充分宽模式与一句理由重试同一条命令一次；批准提示会询问用户，未经批准绝不执行任何东西。本执行器自身绝不协商权限。
+
+### 失败与恢复
+
+如果没有 runner 能强制执行受限模式，前台调用以 `SANDBOX_UNAVAILABLE` 失败，后台进程则记录 runner 失败事实——绝不会静默无隔离运行。可归因于 runner 的 spawn 失败以原始 spawn 错误作为详情；其他 spawn 拒绝保持本地执行器普通的命令启动语义。

+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释执行器的设计并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计概念
+
+本执行器是 `dsh-bash-sandbox` 的 pwsh 孪生：它继承 `dsh-pwsh-local` 的进程机制，消费其 argv 级 seam（`argv()`/`runArgv()`/`startArgv()`/`onProcessDone()`），并在 spawn 前把精确的 pwsh 调用经 `ctx.sandbox.confine()` 包装。隔离实体本身是平台无关的——sandbox seam 解析到平台的 runner——而本包只负责 pwsh 侧：所选模式、强制执行完整度，以及结果上的拒绝分类。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：`SandboxPwshExecutor`、按进程保留事实、run/start 包装 |
+| [`src/helpers.ts`](src/helpers.ts) | 拒绝、runner 失败与 runner spawn 失败分类 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；分类在结果中可观察） |
+| `tests/` | 跨 ACL 与平台 runner 演练的行为 |
+
+### 主要流程
+
+对受限模式，`resolve()` 标记每次调用的策略；`run` 与 `start` 把 pwsh argv 经提供方包装，再把受限 argv 交给继承的 subprocess 路径。结算时执行器对结果分类：runner 失败优先于拒绝（命令从未运行），stderr 携带 runner 拒绝方言的失败运行报告 `denied: true`，每次受限运行都携带模式与强制执行事实。`danger-full-access` 完全绕过提供方，并标记 `denied: false`。
+
+### 不变式
+
+- **失败关闭**——受限模式没有可用 runner 时抛 `SANDBOX_UNAVAILABLE`；受限策略绝不会出现无隔离直通。
+- **seam 只报告拒绝**——本执行器从不授予权限；批准流程位于工具层。
+- **按进程保留事实**——隔离事实在结算前按句柄保留，因为提供方可能在重叠调用之间改变强制执行方式。

-The tool-independent shell environment plugin: owns the `ctx.shellEnv` registry of trusted, per-execution `DSH_*` variables that the model-facing shell tools (`dsh-tool-bash`, `dsh-tool-pwsh`) collect into every shell call's environment. Built-in shell facts (`DSH_HOME`, `DSH_SHELL=1`, `DSH_SESSION_ID`) are owned by the registry itself; other plugins register additional enumerable facts with effect-scoped disposal, and duplicate ownership or undeclared runtime keys fail loudly.
+## Summary
 
-The package root exports the Cordis plugin contract (`name`, `inject`, `Config`, `apply`) plus the `ShellEnvRegistry` service class and its contributor types; consumers use `ctx.shellEnv` after loading this plugin.
+`dsh-shell-env` provides the trusted `DSH_*` environment that every model shell call — bash or pwsh — runs with: built-in facts such as `DSH_HOME`, `DSH_SHELL=1`, and the agent's `DSH_SESSION_ID`, plus `DSH_SESSION_JSONL` when the active persistence backend locates a JSONL artifact. Plugin authors can register their own facts with declared keys, collected per execution and disposed with their plugin; duplicate ownership or undeclared runtime keys fail loudly instead of silently overwriting. The registry changes nothing else the model sees — the shell tools own their own schemas and prompts. Choose it in any composition that mounts a model shell tool; configuration only picks the Harness home directory.

-## Managed environment
+-----
 
-Every foreground and background model shell call receives a newly collected trusted `DSH_*` environment. `DSH_HOME` is the absolute Harness home resolved by [`@deepseek-ai/dsh-home-paths`](../../util/home-paths/README.md) (`dshHome` config, then ambient `$DSH_HOME`, then `~/.dsh`) and `DSH_SHELL=1` identifies the managed child. Agent calls additionally receive `DSH_SESSION_ID=agent.session.header.id`; when the active persistence seam locates a JSONL artifact they also receive `DSH_SESSION_JSONL=<absolute target path>`. The JSONL path is a location hint: it may not exist before the first flush or contain the current buffered turn, and it is not an authorization credential.
+<a id="use-this-package"></a>
+## Use this package
 
-`ctx.shellEnv` owns collection. Other plugins can register an effect-scoped contributor with a stable name, declared keys/descriptions, and `resolve(execution: ToolExecution)`; duplicate ownership and undeclared runtime keys fail loudly, while `list()` enumerates declarations without executing providers. Harness built-ins reserve `DSH_HOME`, `DSH_SHELL`, and `DSH_SESSION_ID`; this plugin's persistence translator owns `DSH_SESSION_JSONL` by reading the backend-neutral `sessionPersistence.locate()` seam.
+Load this plugin in any composition that mounts a model shell tool (`dsh-tool-bash` or `dsh-tool-pwsh`): each foreground or background shell call then runs with a freshly collected managed environment instead of whatever `DSH_*` values the process inherited.
+
+### What every shell call receives
+
+Every call receives `DSH_HOME` (the absolute Harness home), `DSH_SHELL=1`, and, for agent calls, `DSH_SESSION_ID` (the calling session's id). When the active persistence backend locates a JSONL artifact for the session, calls also receive `DSH_SESSION_JSONL` with its absolute target path — a location hint, not a guarantee: the file may not exist before the first flush and may not contain the current buffered turn, and the value is not an authorization credential.
+
+### Adding your own environment facts
+
+Other plugins contribute facts by registering a contributor with a stable name, the complete set of `DSH_*` keys it may return, a description per key, and a resolver that computes values for one execution:
 
 ```ts
 import type { Context } from '@deepseek-ai/cordis'
@@ -36,16 +50,92 @@ export function apply(ctx: Context): void {
 }
 ```
 
-The overlay is computed from the current `ToolExecution` and passed through the dedicated `ShellExecRequest.dshEnv` channel. The local executors remove all inherited `DSH_*` before merging that snapshot, so nested harnesses and concurrent parent/child agents cannot leak stale identities. `process.env` is never modified. The shell tools' descriptions teach the generic `$DSH_*` convention rather than naming persistence-specific variables or adding a permanent system-prompt section.
+Contributors must declare every key they return; returning an undeclared or non-string value fails the call. Registration is disposed with the registering plugin, so hot-reloading a plugin removes its facts.
 
+### Choosing the Harness home
+
+The single config field picks the home directory exposed as `DSH_HOME`; the default resolution order is the `dshHome` config, then ambient `$DSH_HOME`, then `~/.dsh`.
+
+| Field | Default | Meaning |
+|---|---|---|
+| `dshHome` | `$DSH_HOME`, then `~/.dsh` | Absolute Harness home exposed as `DSH_HOME` |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-shell-env) is the exhaustive source for every accepted field and its JSDoc.
+
+### What can go wrong
+
+Two contributors declaring the same key, or a contributor claiming a reserved built-in (`DSH_HOME`, `DSH_SHELL`, `DSH_SESSION_ID`), fails plugin load loudly. A `DSH_*` key must be all-caps with underscores (for example `DSH_REGION`), and a missing description fails registration.

+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the registry and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+- **Trusted namespace, rebuilt per call.** The environment is a Harness-owned `DSH_*` namespace: the shell executor discards inherited `DSH_*` values and merges the registry's current snapshot for each execution, so nested harnesses and concurrent parent/child agents cannot leak stale identities, and `process.env` is never modified.
+- **Declared ownership, loud conflicts.** Contributors declare their keys up front so duplicate ownership is detected before the first command; resolvers may only return declared keys.
+- **Built-ins stay here.** `DSH_HOME`, `DSH_SHELL`, and `DSH_SESSION_ID` are reserved for the registry; `DSH_SESSION_JSONL` is contributed by this plugin's own persistence translator, which reads the backend-neutral `sessionPersistence.locate()` seam.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry, `ShellEnvRegistry` service, built-in facts and the persistence contributor |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; collection is observable through tool execution) |
+
+### Collection
+
+`collect(execution)` starts from the built-ins, adds the session id when the execution carries an agent, then merges each registered contributor's resolved values sorted by contributor name. The result is a frozen, key-sorted snapshot passed through `ShellExecRequest.dshEnv`. `list()` enumerates declarations without running resolvers, so it cannot reflect execution-dependent values.

-The **`ShellExecutor`** (`ctx.shell`) defines WHAT a bash backend does — run foreground commands and start background processes — without saying HOW. Job ids, ownership, collection, cancellation, and notices belong to the generic `ctx.jobs` runtime.
+## Summary
 
-This package owns the Service Definition role of the bash capability, split so each role can evolve (and be swapped) independently:
+`dsh-shell` defines the executor service (`ctx.shell`) that runs shell commands for the harness: foreground commands that resolve with bounded output when they finish, and background processes that return a handle immediately. Every shell executor in the repository — local Bash, sandboxed Bash, local PowerShell, sandboxed PowerShell — implements this one contract, so the model-facing `bash` and `pwsh` tools work unchanged over any of them. Callers pass a request and receive a fully-resolved spec with explicit defaults and caps before any command runs. The service itself never renders anything to a model; the shell tools own all model-visible output and sandbox guidance.

+<a id="use-this-package"></a>
+## Use this package
+
+Use `ctx.shell` when an agent or an in-process plugin needs to run a shell command and read its output, or start a background process and poll it. It is the contract every shell executor and the model-facing `bash`/`pwsh` tools build on, so code written against it works over any executor implementation.
+
+### Foreground commands
+
+Call `run` with a resolved spec to execute a command in the foreground. The promise resolves when the command finishes: a nonzero exit, an executor timeout kill, or a caller abort kill is a result, never a rejection. `run` rejects only for infrastructure failures such as an unusable working directory or a missing shell. The result carries the exit code or signal, whether a timeout or an abort cut the run short, and the collected stdout/stderr with spill-file paths when a stream overflowed its budget.
+
+```text
+const result = await ctx.shell.run(ctx.shell.resolve({ command: 'ls -la' }))
+console.log(result.exitCode, result.stdout.text)
+```
+
+### Background processes
+
+Call `start` with a resolved spec to launch a background process; it returns a handle immediately and no timeout applies. Read output incrementally with `readOutput()` — consecutive reads never repeat output, and lossy reads point at full-stream spill files. Kill the process group with `kill()` (returns `false` once it has finished) and await `done` for settlement. Job ids, ownership, polling, and notices belong to the generic `ctx.jobs` runtime, where the tool layer registers the handle.
+
+### Requests and resolved specs
+
+Every execution starts from a `ShellExecRequest` with optional fields; the executor's `resolve()` turns it into a fully-resolved `ShellExecSpec` with explicit defaults and caps before anything runs. This request/spec split is the repository's template for explicit resolution at package boundaries: callers never rely on hidden defaults inside `run` or `start`. `resolve()` fills the working directory and timeout from the executor's configuration, caps per-call overrides, and carries optional inputs — `stdin`, ordinary `env`, and the trusted `DSH_*` snapshot — through verbatim.
+
+### Choosing and composing an executor
+
+The seam is not an executor: mount exactly one provider per composition, and the tools work unchanged. On POSIX, `dsh-bash-local` runs commands as fresh `bash -c` processes and `dsh-bash-sandbox` confines every command through the sandbox capability; on Windows, `dsh-pwsh-local` and `dsh-pwsh-sandbox` are the counterparts. The `bash` and `pwsh` tools advertise escalation fields only while a sandboxing executor is mounted. The smallest composition is the executor alone:
+
+```yaml
+- id: bash
+  name: '@deepseek-ai/dsh-bash-local'
+  config:
+    cwd: /path/to/workspace
+```
+
+### The shared exit-status contract
+
+Tool results end with a machine-readable exit marker — `[exit code: N]` or `[killed by signal: X]` — so the model can always tell how a command ended. The seam owns that marker format and the `parseExitStatus` helper that splits a rendered result back into its output body and structured exit status, keeping the `bash` and `pwsh` tools from drifting on it.
+

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design of the seam and points at the code that realizes it; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The package is one role of a standard capability seam: the Service Definition that names the executor contract, with Service Providers and Consumers split so each role evolves independently (see the [capability-seams note](../../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.md)). Two decisions anchor the contract:
+
+- **Explicit resolution at the boundary.** `resolve(request)` is the single place defaults and caps are applied; `run` and `start` accept only resolved specs and never re-default, so no hidden fallback lives inside an implementation.
+- **Task-free background handles.** `start` returns a `ShellProcess` with no id or owner; job identity, ownership, and lifecycle belong to the generic `ctx.jobs` runtime, keeping executors independent of sessions.
+
+### Source map
+
+| File | Role |
 |---|---|
-| `@deepseek-ai/dsh-shell` (this) | Service Definition: abstract service + vocabulary types |
-| `@deepseek-ai/dsh-bash-local` | Service Provider: local subprocesses |
-| `@deepseek-ai/dsh-bash-sandbox` | Service Provider: `dsh-bash-local`'s mechanics with every spawn confined via [`ctx.sandbox`](../../sandbox/sandbox/), denials reported as result facts |
-| `@deepseek-ai/dsh-tool-bash` | the model-facing tool schemas over `ctx.shell` |
+| [`src/index.ts`](src/index.ts) | Plugin entry: abstract `ShellExecutor` service and the shared settings namespace |
+| [`src/types.ts`](src/types.ts) | Request/spec vocabulary, `ShellRunResult`, `ShellProcess`, and sandbox facts |
+| [`src/render.ts`](src/render.ts) | `parseExitStatus`: the exit-status marker contract the shell tools share |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; executors and policy own observations) |
 
-The split is a standard capability seam ([capability-seams Agent Note](../../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.md)): `dsh-bash-sandbox` is a sandboxing executor behind the same Service Definition — the Consumer detects its `sandboxMode` capability and adds escalation fields without importing the provider — and a containerized or remote executor slots in the same way.
+### Settings namespace
 
-## Service API (`ctx.shell`)
+`SHELL_SETTINGS_NAMESPACE` is exported here rather than by a provider because it names the capability, not an implementation: a host composes exactly one provider of `ctx.shell`, so the providers share one namespace without colliding, and a settings document carried between platforms keeps resolving on both.
 
-| Member | Semantics |
-|---|---|
-| `run(spec)` | Foreground execution. Resolves when the command finishes. **Rejects only for infrastructure failures** (unusable workdir, missing shell, pre-aborted signal); nonzero exits, timeout kills, and abort kills resolve with a descriptive `ShellRunResult`. |
-| `start(spec)` | Background execution. Returns a task-free `ShellProcess` handle immediately; **no timeout applies**. The caller may adapt it into `ctx.jobs`. |
-| `sandboxMode` | The capability fact for the tool layer: the default mode a SANDBOXING executor confines under (`undefined` in the base class — "this executor does not sandbox"). `dsh-tool-bash` reads it at registration to advertise the escalation fields only when the composition honors them. |
-| `ShellProcess.readOutput()` | **Incremental** output read — consecutive reads never re-deliver. Reads that lost data to buffer bounds flag `lossy` and point at full-stream spill files. |
-| `ShellProcess.kill()` | Kill the process group. Returns `false` when it already finished. |
+### Background lifecycle and ownership
 
-Implementations subclass `ShellExecutor` and implement the abstract methods. Disposal must kill every running process and await its exit.
+A background process belongs to the subprocess service, not to the executor: it survives an executor-only reload and is killed and joined when the composition tears down. Implementations must honor the seam's semantics — `run` rejects only for infrastructure failures; `start` returns immediately with no timeout and its `done` never rejects (spawn failures settle as `killed` with the error on stderr); `readOutput` is consuming and lossy reads report spill files.
 
-`SHELL_SETTINGS_NAMESPACE` (`bash`) is exported here rather than by a provider because it names the capability, not an implementation. A host composes exactly one provider of `ctx.shell` — the win32 layer swaps the POSIX rows for the pwsh ones, and mounting both fails loud on a duplicate service registration — so every provider can register this one namespace with its own schema and composition entry without two of them ever colliding, and a `settings.yaml` carried between platforms keeps resolving on both.
+</details>
 
-## Vocabulary
+-----
 
-`ShellExecRequest` (command, workdir?, timeoutMs?, stdoutMaxBytes?, signal?, stdin?, env?, dshEnv?, sandboxPolicy?) resolves to `ShellExecSpec` (command, workdir, timeoutMs, stdoutMaxBytes, signal?, stdin?, env?, dshEnv?, sandboxPolicy) before execution. `stdoutMaxBytes` is a trusted foreground-run capture budget for consumers that must parse complete bounded stdout; the model-facing bash tool does not expose it. `sandboxPolicy` is optional on the request and required-but-nullable on the resolved spec: it carries the complete per-call mode and workspace root. The sandbox tool path resolves it from the calling session through `ctx.sandboxPolicy`; a direct sandbox-executor caller falls back to deployment policy, while a non-sandboxing executor carries the field and confines nothing.
+<a id="further-exploration"></a>
+## Further Exploration
 
-The per-session sandbox-mode override vocabulary (the `'sandbox/mode'` event, the `effectiveSandboxMode(events)` fold, and the `setSandboxMode(session, mode)` write path) is NOT here — it is policy state shared by every enforcing family, owned by [`@deepseek-ai/dsh-sandbox-policy`](../../sandbox/sandbox-policy/). `run()` returns `ShellRunResult`; `start()` returns `ShellProcess`, whose incremental read and kill methods are adapted by `dsh-tool-bash` into a generic task registration. A sandboxing executor stamps `ShellSandboxInfo` on foreground results and settled process handles. See `src/types.ts` and [subsystems/shell.md](../../../docs/subsystems/shell.md).
+Read these pages when the seam contract is not enough. They move from the shared subsystem reference to the concrete executors and the model-facing tools.
 
-`stdin` and ordinary `env` are set by in-process plugins (the hooks bridges, native plugins) to feed a hook command its JSON payload and `CLAUDE_PROJECT_DIR`/`CLAUDE_PLUGIN_ROOT` values. `dshEnv` is a separate trusted overlay restricted by type to managed keys; the exported `DSH_ENV_PREFIX` is the single source for that namespace, its `DshEnvironmentKey` template type, executor scrubbing, registry validation, derived built-in names, and model guidance. Model bash uses the current snapshot collected by `ctx.shellEnv`. Implementations remove inherited managed keys, then merge `dshEnv` after ordinary `env`, so an omitted current fact cannot fall back to stale ambient state and an `env` entry cannot displace a managed value. The model-facing tool exposes none of these as parameters. All three remain optional on the resolved spec; absent means no input/overlay. See [the bash-stdin-env Agent Note](../../../.agents/notes/implemented/architecture/2026-06-30-bash-stdin-env-trusted-plugin-api.md) and [the session environment Agent Note](../../../.agents/notes/implemented/feature/2026-07-10-agent-session-identity-and-log-location.md).

Both tools' `presentResult` use it to split the rendered text into the terminal card's output body and its exit-status pill; it lives with the Service Definition so the two tools never drift on the marker contract.

+## 使用本包
+
+当 agent 或进程内插件需要运行 shell 命令并读取输出，或启动后台进程并轮询它时，使用 `ctx.shell`。它是每个 shell 执行器与面向模型的 `bash`/`pwsh` 工具共同依赖的约定，因此基于它编写的代码可以运行在任意执行器实现之上。
+
+### 前台命令
+
+用已解析的 spec 调用 `run` 即可在前台执行命令。promise 在命令结束时 resolve：非零退出、执行器超时终止或调用方中止终止都是结果，绝不是 rejection。`run` 只在基础设施失败时 reject，例如工作目录不可用或缺少 shell。结果携带退出码或信号、是超时还是中止截断了运行，以及收集到的 stdout/stderr；流超出预算时还附带 spill 文件路径。
+
+```text
+const result = await ctx.shell.run(ctx.shell.resolve({ command: 'ls -la' }))
+console.log(result.exitCode, result.stdout.text)
+```
+
+### 后台进程
+
+用已解析的 spec 调用 `start` 即可启动后台进程；它会立即返回句柄，且不应用任何超时。用 `readOutput()` 增量读取输出——连续读取绝不会重复交付，有损读取会指向完整流的 spill 文件。用 `kill()` 终止进程组（进程结束后返回 `false`），并等待 `done` 结算。job id、所有权、轮询与通知属于通用 `ctx.jobs` 运行时，工具层会把句柄注册进去。
+
+### 请求与已解析 spec
+
+每次执行都从带可选字段的 `ShellExecRequest` 开始；执行器的 `resolve()` 在任何东西运行之前，把它变成默认值与上限都已显式填好的 `ShellExecSpec`。这一请求/spec 拆分正是仓库在包边界显式解析的模板：调用方绝不依赖 `run` 或 `start` 内部隐藏的默认值。`resolve()` 从执行器配置填充工作目录与超时、对每次调用的覆盖值设上限，并按原样携带可选输入——`stdin`、普通 `env` 与受信任的 `DSH_*` 快照。
+
+### 选择并组合一个执行器
+
+seam 本身不是执行器：每个组合只挂载一个提供方，工具即可不加改动地工作。在 POSIX 上，`dsh-bash-local` 以全新的 `bash -c` 进程运行命令，`dsh-bash-sandbox` 则通过沙箱能力限制每条命令；在 Windows 上，对应实现是 `dsh-pwsh-local` 与 `dsh-pwsh-sandbox`。`bash` 与 `pwsh` 工具只在挂载沙箱执行器时公布升权字段。最小的组合只需执行器本身：
+
+```yaml
+- id: bash
+  name: '@deepseek-ai/dsh-bash-local'
+  config:
+    cwd: /path/to/workspace
+```
+
+### 共享的退出状态约定
+
+工具结果以机器可读的退出标记结尾——`[exit code: N]` 或 `[killed by signal: X]`——模型因此总能知道命令如何结束。seam 拥有该标记格式，以及把渲染结果拆回输出正文与结构化退出状态的 `parseExitStatus` 辅助函数，使 `bash` 与 `pwsh` 两个工具永远不会在此漂移。

+
+本节解释 seam 的设计并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+本包是标准能力 seam 中的一个角色：命名执行器约定的 Service Definition，Service Provider 与 Consumer 各自拆分，使每个角色都能独立演进（见[能力 seam 笔记](../../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.zh.md)）。两项决策锚定了该约定：
+
+- **边界处的显式解析。** `resolve(request)` 是应用默认值与上限的唯一位置；`run` 与 `start` 只接受已解析的 spec，绝不再次默认化，因此实现内部不会藏有隐藏的兜底值。
+- **无任务语义的后台句柄。** `start` 返回不带 id 或所有者的 `ShellProcess`；job 身份、所有权与生命周期属于通用 `ctx.jobs` 运行时，使执行器与会话保持独立。
+
+### 源码地图

-| `@deepseek-ai/dsh-bash-sandbox` | Service Provider：沿用 `dsh-bash-local` 的机制，但通过 [`ctx.sandbox`](../../sandbox/sandbox/) 限制每次 spawn，并将拒绝报告为结果事实 |
-| `@deepseek-ai/dsh-tool-bash` | 基于 `ctx.shell`、面向模型的工具 schema |

+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；执行器与策略负责观察） |
 
-该拆分是一个标准的能力 seam（[capability-seams Agent Note](../../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.zh.md)）：`dsh-bash-sandbox` 是位于同一 Service Definition 之后的沙箱执行器——Consumer 检测其 `sandboxMode` 能力并添加升权字段，无需导入提供方——容器化或远程执行器也可以同样接入。
+### 设置命名空间
 
-## 服务 API（`ctx.shell`）
+`SHELL_SETTINGS_NAMESPACE` 由此处导出而非由某个提供方导出，因为它命名的是能力而不是实现：一个宿主只组装一个 `ctx.shell` 提供方，因此各提供方共享同一个命名空间而永不冲突，在平台间携带的设置文档也能在两边继续解析。
 
-| 成员 | 语义 |
-|---|---|
-| `run(spec)` | 前台执行。命令完成时 resolve。**只会因基础设施失败而 reject**（工作目录不可用、shell 缺失、信号已在调用前中止）；非零退出、超时终止和中止导致的终止都会 resolve 为描述性 `ShellRunResult`。 |
-| `start(spec)` | 后台执行。立即返回不含任务语义的 `ShellProcess` 句柄；**不应用超时**。调用方可以将其适配到 `ctx.jobs`。 |
-| `sandboxMode` | 工具层的能力事实：沙箱执行器用于限制执行的默认模式（基类中为 `undefined`，即「此执行器不使用沙箱」）。`dsh-tool-bash` 会在注册时读取它，仅当组合确实支持升权字段时才公布这些字段。 |
-| `ShellProcess.readOutput()` | **增量** 读取输出：连续读取绝不会重复交付。因缓冲区容量限制而丢失数据的读取会标记 `lossy`，并指向完整流 spill 文件。 |
-| `ShellProcess.kill()` | 终止进程组。如果进程已结束，返回 `false`。 |
+### 后台生命周期与归属
 
-实现会继承 `ShellExecutor` 并实现抽象方法。dispose（资源释放）必须终止每个运行中的进程并等待其退出。
+后台进程属于 subprocess 服务而非执行器：它能在仅重载执行器后存活，并在组合拆解时被终止并 join。实现必须遵守 seam 的语义——`run` 只在基础设施失败时 reject；`start` 立即返回且不设超时，其 `done` 绝不 reject（spawn 失败以 `killed` 结算，错误进入 stderr）；`readOutput` 是消费式的，有损读取会报告 spill 文件。
 
-`SHELL_SETTINGS_NAMESPACE`（`bash`）由此处导出而非由某个提供方导出，因为它命名的是能力而不是实现。一个宿主只组装一个 `ctx.shell` 提供方——win32 层会把 POSIX 行换成 pwsh 行，同时挂载两者会因服务重复注册而在加载期失败——所以每个提供方都能用自己的 schema 与组装条目注册这同一个命名空间，两者永不相撞；在平台间携带的 `settings.yaml` 也能在两边继续解析。
+</details>
 
-## 词汇
+-----
 
-`ShellExecRequest`（command、workdir?、timeoutMs?、stdoutMaxBytes?、signal?、stdin?、env?、dshEnv?、sandboxPolicy?）在执行前解析为 `ShellExecSpec`（command、workdir、timeoutMs、stdoutMaxBytes、signal?、stdin?、env?、dshEnv?、sandboxPolicy）。`stdoutMaxBytes` 是受信任前台运行的捕获预算，用于必须解析完整有界 stdout 的消费方；面向模型的 bash 工具不公开该字段。`sandboxPolicy` 在请求上可选，在已解析 spec 上必填但可为 null：它携带完整的每次调用模式与工作区根目录。沙箱工具路径通过 `ctx.sandboxPolicy` 从调用会话解析它；沙箱执行器的直接调用方回退到部署策略，非沙箱执行器则携带该字段但不作限制。
+<a id="further-exploration"></a>
+## 进一步探索
 
-每会话沙箱模式覆盖词汇（`'sandbox/mode'` 事件、`effectiveSandboxMode(events)` fold 以及 `setSandboxMode(session, mode)` 写入路径）不位于此处。它是所有强制执行家族共享的策略状态，属于 [`@deepseek-ai/dsh-sandbox-policy`](../../sandbox/sandbox-policy/)。`run()` 返回 `ShellRunResult`；`start()` 返回 `ShellProcess`，其增量读取与终止方法由 `dsh-tool-bash` 适配为通用任务注册。沙箱执行器会在前台结果与已结算进程句柄上标记 `ShellSandboxInfo`。详见 `src/types.ts` 与 [subsystems/shell.md](../../../docs/subsystems/shell.zh.md)。
+当 seam 约定不够用时阅读以下页面。它们从共享子系统参考逐步进入具体执行器与面向模型的工具。
 
-`stdin` 与普通 `env` 由同进程插件（hooks 桥接、原生插件）设置，用于向 hook 命令提供其 JSON payload 和 `CLAUDE_PROJECT_DIR`／`CLAUDE_PLUGIN_ROOT` 值。`dshEnv` 是受类型限制、仅允许受管 key 的独立受信任 overlay；导出的 `DSH_ENV_PREFIX` 是该 namespace、其 `DshEnvironmentKey` 模板类型、执行器清理、注册表验证、派生内置名称与模型指引的统一来源。模型 bash 使用 `ctx.shellEnv` 收集的当前快照。实现会移除继承的受管 key，再在普通 `env` 之后合并 `dshEnv`，因此省略的当前事实不会回退到陈旧环境状态，`env` 条目也无法顶掉受管值。面向模型的工具不将这三者中的任何一个公开为参数。这三者在已解析 spec 上仍然可选；缺失表示没有输入／overlay。详见 [bash-stdin-env Agent Note](../../../.agents/notes/implemented/architecture/2026-06-30-bash-stdin-env-trusted-plugin-api.zh.md) 与 [会话环境 Agent Note](../../../.agents/notes/implemented/feature/2026-07-10-agent-session-identity-and-log-location.zh.md)。
+- [Bash 执行器子系统](../../../docs/subsystems/shell.zh.md) —— 请求/spec 词汇、结果与完整的服务约定。
+- [bash-local](../bash-local/README.zh.md) —— 默认 POSIX 执行器：全新的 `bash -c` 进程、预算与 deadline。
+- [bash-sandbox](../bash-sandbox/README.zh.md) —— 受限执行器：沙箱模式、拒绝与升权。
+- [tool-bash](../tool-bash/README.zh.md) —— 基于该 seam 的面向模型 `bash` 工具。
+- [能力 seam 笔记](../../../.agents/notes/implemented/architecture/2026-06-13-capability-seams.zh.md) —— 本 seam 遵循的 Service Definition / Provider / Consumer 拆分。
 
-导出的 `parseExitStatus`（连同 `ParsedExitStatus`）是 shell 工具共享渲染约定的另一半：`dsh-tool-bash` 的 `renderResult` 与 `dsh-tool-pwsh` 的 `renderPwshResult` 追加的 `[exit code: N]`／`[killed by signal: X]` marker 的逆解析。两个工具的 `presentResult` 都用它把渲染文本拆成 terminal 卡的输出正文与其退出状态 pill；它放在 Service Definition 中，两个工具便永远不会在 marker 约定上漂移。

-Model-facing `bash(command)` backed by one owner-scoped `ctx.terminals` shell. The package owns the tool contract and shell reuse; deployments select the PTY backend and sandbox policy.
+## Summary
 
-## Config
+`dsh-tool-bash-persistent` gives the agent a `bash` tool whose shell state persists across calls for the owning agent: cwd, exported variables, functions, and background jobs survive between commands. Each agent gets its own shell backed by an owner-scoped PTY session from the terminal service, and commands for the same agent run one at a time. Configuration selects the PTY backend and the wall-clock limit for one command; a timeout or an explicit `exit` closes the shell, and the next call starts fresh. It complements the one-shot `dsh-tool-bash` tool — choose it when work needs cross-call state. Mount it together with a terminal backend such as `dsh-terminal-bash` and the `ctx.terminals` service.
 
-| Key | Default | Meaning |
-|---|---:|---|
-| `backendType` | `shell` | Registered PTY backend used for each Agent shell. |
-| `timeoutMs` | `300000` | Wall-clock limit for one command; timeout closes the shell. |
-| `maxOutputChars` | `16000` | Maximum retained command-output characters; fixed diagnostics are added afterward. |
-| `description` | Persistent-shell description | Model-facing environment contract. |

+## Use this package
+
+Load this plugin in any composition where the agent should keep shell state between commands — for example long build sessions, activated environments, or scripts that export variables for later steps. It registers the `bash` tool and requires the `ctx.tools` and `ctx.terminals` services plus an owning agent session at execution time.
+
+### When to choose it
+
+Choose the persistent tool when work depends on cross-call state: a one-shot `dsh-tool-bash` call cannot remember a `cd` or an exported variable. Choose the one-shot tool when every command should start from a known, clean environment, or when the command is short and self-contained. Commands that need interactive stdin are unsupported here — a foreground child that reads input blocks until the command timeout — so interactive work belongs to the terminal tools.
+
+### Minimal configuration
+
+The default `shell` backend starts an interactive bash through `dsh-terminal-bash`; deployments may register another PTY backend and select it by name.
+
+```yaml
+- name: '@deepseek-ai/dsh-terminal'
+- name: '@deepseek-ai/dsh-terminal-bash'
+- name: '@deepseek-ai/dsh-tool-bash-persistent'
+```
+
+| Field | Default | Meaning |
+|---|---|---|
+| `backendType` | `shell` | Registered PTY backend used for each agent's shell |
+| `timeoutMs` | `300,000` | Wall-clock limit for one command; timeout closes the shell |
+| `maxOutputChars` | `16,000` | Maximum retained command-output characters; fixed diagnostics are added afterward |
+| `description` | `Run commands in a persistent bash shell. State, including the current directory and exported environment variables, persists across calls for this agent.` | Model-facing environment contract; deployments may describe their environment |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-tool-bash-persistent) is the exhaustive source for every accepted field and its JSDoc.
+
+### What the agent can rely on
+
+Commands share one shell per agent, so state persists until an `exit`, a timeout, or a reset — each of which closes the shell and tells the agent the next call starts from the workspace with a fresh directory and environment. Results exclude the private completion markers; a non-zero wrapped command appends `[exit code: N]`, and a shell that exits before reporting that status instead appends `[shell exited: code N]`, `[shell killed by signal: SIG]`, or `[shell exited]`, then resets. Long output keeps the earliest retained prefix plus a clipping notice; if the terminal has already dropped that prefix, the result says so explicitly rather than presenting a tail as complete output.
+
+### What can go wrong
+
+A call without an owning agent session fails with `bash requires an owning agent session`, and a composition without a PTY backend activates the tool but fails its first call with `no PTY backend registered for "shell"`. An interactive foreground child (for example a REPL) returns early with partial output only where the backend proves its stdin wait; elsewhere the call runs to `timeoutMs`, which closes the uncertain shell and reports the reset. Cancellation also resets and discards the result, even when a complete status marker is already observable.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the tool and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+- **One shell per owner, nothing shared.** The shell registry keys every session by the calling `Agent`, so concurrent agents never share state, and commands for the same agent are serialized through a per-owner queue.
+- **Marker-anchored extraction.** Each command is wrapped with unique start/end markers carrying the exit status; the tool polls the PTY scrollback and extracts the span between the real markers, so prompts and echoed input never leak into results.
+- **Reset, never repair.** Any uncertain state — an explicit `exit`, a timeout, a send failure, an abort — closes the shell and starts the next call fresh, because a half-known shell is worse than a clean one.
+- **Owner-scoped lifecycle.** Shells are created lazily on first use and killed on plugin disposal or owner teardown; the owner-scoped `ctx.terminals` service fences every operation to the owning agent.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: shell registry, command wrapping, scrollback polling, extraction and rendering |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; shell reuse is observable through tool execution) |
+
+### Command flow
+
+A first command spawns the shell through `ctx.terminals.spawn`, disables input echo (`stty -echo`), and waits for readiness. Each command is then wrapped into one physical line — a printf of the start marker, the command body escaped with `$'…'`, and a printf of the end marker plus `$?` — so embedded newlines cannot leak terminal prompts into the result. The tool polls the scrollback in 1,000-line pages until the end marker appears, extracts the span, and renders it with any status marker. A timeout aborts the deadline, captures the partial output, and resets the shell.

-模型可见的 `bash(command)`，底层复用一个按所有者隔离的 `ctx.terminals` shell。该包拥有工具约定和 shell 复用；PTY 后端与沙箱策略由部署选择。
+## 概述
 
-## 配置

+## 使用本包
+
+在 agent 需要在命令之间保持 shell 状态的任何组合中加载本插件——例如长时间构建会话、已激活的环境，或为后续步骤导出变量的脚本。它注册 `bash` 工具，需要 `ctx.tools` 与 `ctx.terminals` 服务，并在执行时需要拥有者 agent 会话。
+
+### 何时选择
+
+当工作依赖跨调用状态时选择持久工具：一次性 `dsh-tool-bash` 调用无法记住 `cd` 或导出的变量。当每条命令都应从已知、干净的环境开始，或命令又短又独立时，选择一次性工具。这里不支持需要交互 stdin 的命令——读取输入的前台子进程会一直阻塞到命令超时——因此交互工作属于 terminal 工具。
+
+### 最小配置
+
+默认的 `shell` 后端通过 `dsh-terminal-bash` 启动交互式 bash；部署方可以注册其他 PTY 后端并按名称选择。
+
+```yaml
+- name: '@deepseek-ai/dsh-terminal'
+- name: '@deepseek-ai/dsh-terminal-bash'
+- name: '@deepseek-ai/dsh-tool-bash-persistent'
+```
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `backendType` | `shell` | 用于每个 agent shell 的已注册 PTY 后端 |
+| `timeoutMs` | `300,000` | 单条命令的墙钟上限；超时关闭 shell |
+| `maxOutputChars` | `16,000` | 保留的命令输出字符上限；固定诊断信息在其后追加 |
+| `description` | `Run commands in a persistent bash shell. State, including the current directory and exported environment variables, persists across calls for this agent.` | 面向模型的环境约定；部署方可描述自己的环境 |
+
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-tool-bash-persistent)是每个受支持字段及其 JSDoc 的穷尽式真源。
+
+### agent 可以依赖什么
+
+命令共享每个 agent 一个 shell，因此状态一直保留到 `exit`、超时或重置——每一种都会关闭 shell 并告诉 agent 下一次调用从工作区的新目录与环境开始。结果排除私有完成标记；非零的包装命令追加 `[exit code: N]`，而在报告该状态前就退出的 shell 改为追加 `[shell exited: code N]`、`[shell killed by signal: SIG]` 或 `[shell exited]`，然后重置。长输出保留最早的已保留前缀并附裁剪通知；若 terminal 已经丢弃该前缀，结果会明确说明，而不是把尾部当作完整输出呈现。
+
+### 可能出什么问题
+
+没有拥有者 agent 会话的调用会以 `bash requires an owning agent session` 失败，没有 PTY 后端的组合会激活该工具，但首次调用以 `no PTY backend registered for "shell"` 失败。交互式前台子进程（例如 REPL）只有在后端证明其 stdin 等待时才提前返回部分输出；否则调用一直运行到 `timeoutMs`，随后关闭不确定的 shell 并报告重置。取消也会重置并丢弃结果，即使完整状态标记已经可观察。

+
+### 设计理念
+
+- **每个 owner 一个 shell，互不共享。** shell 注册表按调用方 `Agent` 为每个会话建键，因此并发 agent 永不共享状态，同一 agent 的命令通过按 owner 的队列串行化。
+- **标记锚定提取。** 每条命令都用携带退出状态的唯一起止标记包装；工具轮询 PTY scrollback 并提取真实标记之间的区间，因此提示词与回显输入永不泄漏进结果。
+- **重置，而非修复。** 任何不确定状态——显式 `exit`、超时、发送失败、中止——都会关闭 shell 并让下一次调用从全新状态开始，因为半知情的 shell 不如干净的 shell。
+- **按 owner 的生命周期。** shell 在首次使用时惰性创建，在插件释放或 owner 拆除时终止；按所有者隔离的 `ctx.terminals` 服务把每个操作都围栏到拥有它的 agent。

 # @deepseek-ai/dsh-tool-bash
 
 English | [中文](README.zh.md)
 
-The model-facing `bash` tool registered over the `ctx.shell` executor seam. Foreground execution stays behind that seam; a background process handle is registered with the generic `ctx.jobs` runtime and controlled through `job_output`, `job_list`, and `job_kill` from `@deepseek-ai/dsh-tool-jobs`.
+## Summary
 
-Requires a loaded executor Service Provider (e.g. `@deepseek-ai/dsh-bash-local`) and the [`@deepseek-ai/dsh-shell-env`](../shell-env/README.md) registry; the plugin stays pending until every injected service exists (`inject: ['tools', 'bash', 'systemPrompt', 'bashEnv']`). The tool contract is bash-dialect — mount a bash-parsing executor.
+`dsh-tool-bash` gives the agent a `bash` tool that runs commands through the mounted shell executor and returns stdout, stderr, and exit markers. Each call runs in a fresh shell — no cwd, variables, or functions survive — and `run_in_background` turns long-running commands into background jobs the agent collects with `job_output` and stops with `job_kill`. Every call runs with the managed `DSH_*` environment from `dsh-shell-env`, and under a sandboxing executor a denied command may be retried once with a wider `sandbox_permissions` mode plus a `justification` through user approval. Non-zero exits are reported, not failed, so the agent decides how to react. Mount it together with an executor provider such as `dsh-bash-local` or `dsh-bash-sandbox` and the `dsh-shell-env` plugin.
 
-The package root exposes only the Cordis plugin contract (`name`, `inject`, `Config`, `apply`); result rendering and background-process adaptation remain package-internal.
+## Table of Contents
 
-The plugin also contributes the `tool:bash` prompt section (first-party order 1000): check the `[exit code: N]` marker on every result and investigate failures before moving on.

-## Tools
+-----
 
-### `bash`
+<a id="use-this-package"></a>
+## Use this package
 
-| Arg | Type | Notes |
+Load this plugin in any composition where the agent should run bash commands: it registers the `bash` tool once an executor provider and the `dsh-shell-env` registry are mounted, and stays pending until the `tools`, `shell`, `systemPrompt`, and `shellEnv` services exist.
+
+### Minimal configuration
+
+The common path is an executor provider, the environment registry, and this tool; add the job runtime when the agent may run commands in the background.
+
+```yaml
+- name: '@deepseek-ai/dsh-bash-local'
+- name: '@deepseek-ai/dsh-shell-env'
+- name: '@deepseek-ai/dsh-tool-bash'
+
+# Optional: background jobs
+- name: '@deepseek-ai/dsh-jobs-local'
+- name: '@deepseek-ai/dsh-tool-jobs'
+```
+
+The single config field toggles background support.
+
+| Field | Default | Meaning |
 |---|---|---|
-| `command` | string (required) | Run via `bash -c`. No state persists between calls — use `workdir`, not `cd`. |
-| `description` | string (required) | One-line, active-voice summary of the command (5-10 words), for UI/log display only — no effect on execution. |
-| `timeoutMs` | number | Timeout override in milliseconds. The executor applies its configured default and cap. |
-| `workdir` | string | Working directory for this call. Defaults to the filesystem identity of the calling agent's session cwd (`session.header.cwd`) so each session runs in its own workspace; a relative `workdir` is resolved against that same identity. |
-| `run_in_background` | boolean | Return a job id immediately; no timeout applies. |
-| `sandbox_permissions` | string enum | ADVERTISED ONLY when the mounted executor sandboxes (`ctx.shell.sandboxMode` reports a confining default): the wider mode a denied command needs, from the closed target vocabulary `workspace-write`/`danger-full-access` (never cut down to the executor's default — the effective mode is per-session; strict widening is checked at execution against it, and a non-widening request fails without prompting anyone). |
-| `justification` | string | Required together with `sandbox_permissions` (each without the other is a validation error): one sentence for the user explaining why this exact command needs the wider access. |
+| `enableRunInBackground` | `true` | Expose `run_in_background`; when `false`, forced background calls are rejected |
 
-`command`, `workdir`, and `timeoutMs` are resolved against the executor's config defaults via `ctx.shell.resolve()` before execution, so the Service Definition (`ShellExecSpec`) receives explicit `workdir`/`timeoutMs` values. The workdir default is applied in the tool layer from the calling agent's `session.header.cwd` BEFORE `resolve()` — the per-session cwd must come from `exec.agent`, since N sessions share one executor; only when no session cwd is available does the executor fall back to its own config / `process.cwd()`. When sandbox policy is present, the tool reuses its already-canonical `workspaceRoot` as the workdir base so confinement and process launch cannot resolve the same session spelling differently.
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-tool-bash) is the exhaustive source for every accepted field and its JSDoc; the generated [tool catalog](../../../docs/tool-catalog.md#deepseek-aidsh-tool-bash) carries the full argument schema.
 
-### Managed shell environment
+### Running a command
 
-Every foreground and background model bash call receives a freshly collected trusted `DSH_*` environment through the shared [`dsh-shell-env`](../shell-env/README.md) registry: `DSH_HOME` (the absolute Harness home), `DSH_SHELL=1`, the agent's `DSH_SESSION_ID`, and `DSH_SESSION_JSONL` when the active persistence backend locates one. The registry contract — contributor registration, loud duplicate/undeclared-key failure, the built-in reservations, and the contributor example — lives in that package's README. The snapshot passes through the dedicated `ShellExecRequest.dshEnv` channel; the local executor removes all inherited `DSH_*` before merging it, so nested harnesses and concurrent parent/child agents cannot leak stale identities, and `process.env` is never modified. The tool description teaches the generic `$DSH_*` convention rather than naming persistence-specific variables or adding a permanent system-prompt section.
+The tool executes `bash -c <command>` and returns the combined output. Commands run in a fresh shell every call, so state never persists — pass `workdir` instead of `cd`. A non-zero exit is reported as `[exit code: N]` for the agent to interpret, not surfaced as a tool error. A `description` in active voice (5–10 words) labels the call in the UI; `timeoutMs` overrides the executor's default and cap. Output beyond the executor's stream caps is truncated to its tail, with the full output saved to a spill file whose path is reported.
 
-Result text contains stdout, an optional `[stderr]` section, then applicable sandbox-denial, timeout, signal, exit-code, and truncation markers. Timeout is reported independently of final exit status; nonzero exit remains a model-interpreted result rather than `isError`. Truncation links a safe complete spill file or reports it unavailable. Only infrastructure failures such as spawn errors and aborts produce `isError`.
+### Running long commands in the background
 
-The canonical success is `{ kind: 'foreground', ...ShellRunResult }` for a completed foreground process or `{ kind: 'background', jobId }` for a published task. The Native renderer preserves the text above, including exactly `started background job <id>`; programmatic consumers use the typed fields without parsing those strings. Executor stream caps remain acquisition limits on `ShellRunResult` and carry their spill paths.
+Passing `run_in_background: true` returns a job id immediately and no timeout applies; the command keeps running while the agent works on something else. The agent reads its output with `job_output` (non-blocking unless `wait: true`), lists jobs with `job_list`, and stops it with `job_kill`; a finished job notifies the owning agent in-session. Background support needs the generic job runtime (`dsh-jobs-local`) and its control tools (`dsh-tool-jobs`) mounted.
 
-When `run_in_background` is true, this plugin preflights `ctx.jobs.start()` before spawning, registers the calling agent as owner, and adapts the returned `ShellProcess` handle into generic cancel/done/incremental-output hooks. The job runtime owns ids, cross-session isolation, completion notices, waiting, and disposal cleanup; this plugin only maps bash exit/sandbox facts into job output and outcome detail. `enableRunInBackground: false` removes the parameter and rejects a forced background call at execution time.
+### Sandboxed execution and escalation
 
-## UI presentation
+When the mounted executor confines commands (for example `dsh-bash-sandbox`), a blocked file operation is reported as `[sandbox: file access denied under <mode> mode]` — a policy denial, not a command failure. The model may then retry the exact same command once in the same turn with `sandbox_permissions` (the narrowest wider mode that suffices) and a one-sentence `justification`; the approval prompt raised by that retry is how the user consents. Escalation is never speculative: a request with no real prior denial, or one that is not strictly wider than the current mode, fails closed without running anything, and a rejected escalation is final for that command.
 
-The tool owns its `presentCall`/`presentResult` render intent. A foreground call is a terminal card carrying command, description, cwd, output, and parsed exit status. Because the card shows the exit as its own pill, the `[exit code: N]` / `[killed by signal: …]` marker the parse consumes leaves the output; every other marker (truncation, timeout, sandbox) stays in it. A background start is a generic execute card because it returns only a job id; the generic `job_*` tools own their own cards. These presenters are pure and replay-safe.
+### What can go wrong
 
-## The tool builds its request from named args only
+A composition with no executor provider never activates the tool. Background calls without the job runtime fail with `background jobs unavailable: load @deepseek-ai/dsh-jobs and @deepseek-ai/dsh-tool-jobs`, and `sandbox_permissions` without a sandboxing executor fails with `sandbox_permissions is not available in this composition (no sandboxing executor to escalate)`. `enableRunInBackground: false` removes the parameter and rejects a forced background call at execution time.
 
-`ShellExecRequest` carries optional `stdoutMaxBytes`, `stdin`, ordinary `env`, and managed `dshEnv`, used by trusted in-process plugins and this tool's environment registry. The model-facing tool exposes none of `stdoutMaxBytes`, `stdin`, or `env`: it builds requests from named command/workdir/timeout/signal/sandbox fields plus the registry-collected `dshEnv`. Extra model keys are ignored and cannot replace managed values. Shell syntax provides equivalent command-level behavior, while the local executor scrubs ambient credentials and stale `DSH_*` values. See the [stdin/env Agent Note](../../../.agents/notes/implemented/architecture/2026-06-30-bash-stdin-env-trusted-plugin-api.md).
+-----
 
-## Permissions and escalation
+<a id="understand-the-implementation"></a>
+## Understand the implementation
 
-Commands run with the executor's full authority unless a sandboxing executor ([`dsh-bash-sandbox`](../bash-sandbox/)) confines them — the deny-only sandbox reports denials as result facts, rendered here as the denial marker; per-call allow/deny/ask policy is the `tools/pre-execute` waterfall (see docs/architecture.md).
+<details>
+<summary>Implementation internals — click to expand</summary>
 
-Escalating bash calls resolve `ctx.approval` before execution. `allowed-once` applies the requested mode only to that call; rejection, cancellation, unavailability, or missing approval context executes nothing and returns a distinct error. On a real denial, the model may retry the same command once in the same turn with the narrowest sufficient mode and justification; the approval prompt itself is the consent step. Escalation is never speculative, and a disabled or rejected approval is final. The [sandbox Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md) owns the rationale.
+This section explains the design decisions behind the tool and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
 
-## Per-session mode switching
+### Design philosophy
 
-For sandboxing executors, each call resolves mode as one-shot escalation, then session override, then executor default. Non-sandboxing and agent-less calls carry no session override. The policy owner contributes the current capability-neutral standing mode; denial results still own the operation-specific effective mode and retry guidance. See the [`dsh-shell` fold](../shell/README.md) and [sandbox switching contract](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.md).
+- **Model-facing consumer of the shell seam.** The tool is the Consumer role of the bash capability: it registers the `bash` schema, renders results, and resolves per-call policy, while the executor seam owns process mechanics.
+- **Request from named args only.** The tool never exposes `stdin`, `env`, or `stdoutMaxBytes`; it builds each request from command/workdir/timeout/signal fields plus the registry-collected `dshEnv`, so model-supplied keys cannot replace managed values ([bash stdin/env Agent Note](../../../.agents/notes/implemented/architecture/2026-06-30-bash-stdin-env-trusted-plugin-api.md)).
+- **Non-zero exits are reported, not errored.** Only infrastructure failures (spawn errors, aborts) surface as tool errors; the model interprets exit codes and markers.
+- **Background work belongs to the job runtime.** A background call registers a process handle with `ctx.jobs`; ids, ownership, completion notices, and disposal are the runtime's, and this tool only maps bash exit and sandbox facts into job output.
 
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: tool registration, prompt section, arg validation, escalation, request assembly |
+| [`src/background.ts`](src/background.ts) | Map a settled background process onto generic job outcome vocabulary |
+| [`src/render.ts`](src/render.ts) | Model-facing result text: streams, markers, truncation notices |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; execution relations are owned by the capability seam) |
+
+### Request resolution
+
+The tool resolves the workdir before `ctx.shell.resolve()` runs: an explicit relative `workdir` is resolved against the session cwd, and a sandbox policy's canonical workspace root wins so confinement and launch use the same identity. Sandbox policy resolves per call through `ctx.sandboxPolicy`; an escalation request goes through `ctx.approval` before anything executes, and the tool fails at load if the executor confines but no policy service is mounted.
+
+### Rendering story
+
+The result text is stdout, then a marked `[stderr]` section, then conditional markers: truncation notice, sandbox denial (plus the same-turn escalation hint when the composition advertises escalation), timeout, signal, and exit code — each on its own line. The exit marker doubles as the UI card's exit-status pill: the shared `parseExitStatus` from `dsh-shell` consumes it from the output body, so replay shows the pill without duplicating the marker.

-模型侧 `bash` 工具，注册在 `ctx.shell` 执行器 seam 上。前台执行始终位于该 seam 之后；后台进程句柄会注册到通用 `ctx.jobs` 运行时，并通过 `job_output`、`job_list` 和 `job_kill` 控制；这些工具由 `@deepseek-ai/dsh-tool-jobs` 提供。
+## 概述
 
-需要加载执行器 Service Provider（例如 `@deepseek-ai/dsh-bash-local`）与 [`@deepseek-ai/dsh-shell-env`](../shell-env/README.zh.md) 注册表；在每个注入服务就绪之前，插件会保持等待状态（`inject: ['tools', 'bash', 'systemPrompt', 'bashEnv']`）。工具约定是 bash 方言——请挂载能解析 bash 的执行器。
+`dsh-tool-bash` 为 agent 提供 `bash` 工具，通过已挂载的 shell 执行器运行命令并返回 stdout、stderr 与退出标记。每次调用都运行在全新 shell 中——cwd、变量或函数都不会保留——而 `run_in_background` 把长时间运行的命令变成后台任务，agent 用 `job_output` 收集、用 `job_kill` 停止。每次调用都运行在来自 `dsh-shell-env` 的受管 `DSH_*` 环境中；在沙箱执行器下，被拒绝的命令可以携带更宽的 `sandbox_permissions` 模式和一句 `justification`，经用户审批后在同一轮次内重试一次。非零退出只会被报告、不会失败，因此由 agent 决定如何应对。请与 `dsh-bash-local` 或 `dsh-bash-sandbox` 等执行器提供方以及 `dsh-shell-env` 插件一起挂载。
 
-包根只公开 Cordis 插件约定（`name`、`inject`、`Config`、`apply`）；结果渲染和后台进程适配仍保留在包内部。
+## 目录
 
-插件还会提供 `tool:bash` 提示词段落（first-party 顺序 1000）：检查每个结果中的 `[exit code: N]` 标记，发现失败时先调查原因再继续。

-## 工具

-### `bash`
+<a id="use-this-package"></a>
+## 使用本包
 
-| 参数 | 类型 | 说明 |
+在 agent 需要运行 bash 命令的任何组合中加载本插件：一旦挂载执行器提供方与 `dsh-shell-env` 注册表，它就注册 `bash` 工具，并在 `tools`、`shell`、`systemPrompt` 与 `shellEnv` 服务就绪之前保持等待。
+
+### 最小配置
+
+常用路径是执行器提供方、环境注册表与本工具；当 agent 需要后台运行命令时，再添加任务运行时。
+
+```yaml
+- name: '@deepseek-ai/dsh-bash-local'
+- name: '@deepseek-ai/dsh-shell-env'
+- name: '@deepseek-ai/dsh-tool-bash'
+
+# Optional: background jobs
+- name: '@deepseek-ai/dsh-jobs-local'
+- name: '@deepseek-ai/dsh-tool-jobs'
+```
+
+唯一的配置字段用于开关后台支持。
+
+| 字段 | 默认值 | 含义 |
 |---|---|---|
-| `command` | string（必填） | 通过 `bash -c` 运行。调用之间不保留状态；请使用 `workdir`，不要使用 `cd`。 |
-| `description` | string（必填） | 用一行主动语态概述命令（5～10 个词），仅用于 UI／日志显示，不影响执行。 |
-| `timeoutMs` | number | 以毫秒为单位覆盖超时时间。执行器会应用其配置的默认值和上限。 |
-| `workdir` | string | 本次调用的工作目录。默认为调用方 agent（智能体）会话 cwd 的文件系统标识（`session.header.cwd`），使每个会话都在自己的工作区中运行；相对 `workdir` 也以同一标识为基准解析。 |
-| `run_in_background` | boolean | 立即返回 job id；不应用超时。 |
-| `sandbox_permissions` | string enum | 仅当已挂载的执行器启用沙箱时才会公开（`ctx.shell.sandboxMode` 报告一个具有限制作用的默认值）：被拒命令所需的更宽模式，取自封闭的目标词汇 `workspace-write`/`danger-full-access`（绝不能缩减为执行器默认值；有效模式按会话确定，执行时会基于它检查是否严格拓宽，未拓宽的请求直接失败，不会向任何人发起提示）。 |
-| `justification` | string | 必须与 `sandbox_permissions` 一同提供（缺少任一项都会产生验证错误）：用一句话向用户解释此命令为何需要这项更宽权限。 |
+| `enableRunInBackground` | `true` | 暴露 `run_in_background`；为 `false` 时拒绝强制后台调用 |
 
-执行前，`command`、`workdir` 和 `timeoutMs` 会通过 `ctx.shell.resolve()` 依据执行器配置默认值完成解析，因此 Service Definition（`ShellExecSpec`）收到显式的 `workdir`/`timeoutMs` 值。工具层会根据调用方 agent 的 `session.header.cwd` 应用工作目录默认值，然后才调用 `resolve()`：由于 N 个会话共享一个执行器，逐会话 cwd 必须来自 `exec.agent`；只有无法取得会话 cwd 时，执行器才回退到自身配置／`process.cwd()`。存在沙箱策略时，工具会复用已经规范化的 `workspaceRoot` 作为工作目录基准，防止限制逻辑与进程启动过程对同一个会话路径拼写产生不同解析结果。
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-tool-bash)是每个受支持字段及其 JSDoc 的穷尽式真源；生成的[工具目录](../../../docs/tool-catalog.zh.md#deepseek-aidsh-tool-bash)携带完整参数 schema。
 
-### 托管 shell 环境
+### 运行命令
 
-每次模型发起的前台或后台 bash 调用都会通过共享的 [`dsh-shell-env`](../shell-env/README.zh.md) 注册表收到新收集的一组可信 `DSH_*` 环境变量：`DSH_HOME`（Harness home 绝对路径）、`DSH_SHELL=1`、agent 的 `DSH_SESSION_ID`，以及当活跃持久化后端能定位时的 `DSH_SESSION_JSONL`。注册表约定——贡献方注册、重复键／未声明键的显式报错机制、内置项保留与贡献方示例——载于该包的 README。快照通过专用的 `ShellExecRequest.dshEnv` 通道传递；本地执行器会先删除继承的所有 `DSH_*` 再合并，因此嵌套 harness 和并发的父／子 agent 不会泄漏陈旧身份，且绝不修改 `process.env`。工具说明只教授通用 `$DSH_*` 约定，不会点名持久化专用变量，也不会添加永久的系统提示词段落。
+工具执行 `bash -c <command>` 并返回合并后的输出。命令每次调用都运行在全新 shell 中，因此状态从不保留——请传 `workdir` 而不是 `cd`。非零退出以 `[exit code: N]` 报告给 agent 解读，而不是作为工具错误抛出。主动语态的 `description`（5–10 个词）在 UI 中标注该调用；`timeoutMs` 覆盖执行器的默认值与上限。超出执行器流上限的输出会被截断为尾部，完整输出保存到 spill 文件并报告其路径。
 
-结果文本依次包含 stdout、可选的 `[stderr]` 段落和适用的沙箱拒绝、超时、信号、退出代码及截断标记。超时与最终退出状态分别报告；非零退出仍是由模型解释的结果，不会成为 `isError`。截断结果会链接安全的完整 spill 文件，或报告文件不可用。只有 spawn 错误和中止等基础设施故障才会产生 `isError`。
+### 后台运行长时间命令
 
-已完成前台进程的规范成功值为 `{ kind: 'foreground', ...ShellRunResult }`，已发布任务则为 `{ kind: 'background', jobId }`。Native renderer 保留上述文本，包括精确的 `started background job <id>`；程序化消费方使用带类型字段，无需解析这些字符串。执行器的流上限仍是 `ShellRunResult` 的采集限制，并携带其 spill 路径。
+传入 `run_in_background: true` 会立即返回 job id，不应用超时；命令继续运行，agent 同时处理其他事情。agent 用 `job_output` 读取输出（除非 `wait: true`，否则非阻塞）、用 `job_list` 列出任务、用 `job_kill` 停止任务；完成的任务会在会话内通知拥有它的 agent。后台支持需要挂载通用任务运行时（`dsh-jobs-local`）及其控制工具（`dsh-tool-jobs`）。
 
-当 `run_in_background` 为 true 时，此插件会在 spawn 前预检 `ctx.jobs.start()`，把调用方 agent 注册为持有者，并将返回的 `ShellProcess` 句柄适配为通用的取消／完成／增量输出钩子。任务运行时负责 job id、跨会话隔离、完成通知、等待和 dispose（资源释放）清理；此插件只把 bash 退出／沙箱事实映射为任务输出和结果详情。`enableRunInBackground: false` 会移除该参数，并在执行时拒绝强制后台调用。
+### 沙箱执行与升权
 
-## UI 展示
+当已挂载的执行器约束命令（例如 `dsh-bash-sandbox`）时，被阻止的文件操作会报告为 `[sandbox: file access denied under <mode> mode]`——这是策略拒绝，不是命令失败。模型随后可以在同一轮次中用 `sandbox_permissions`（满足需要的最窄更宽模式）与一句 `justification` 重试完全相同的命令一次；该重试引发的审批提示就是用户同意的方式。升权绝不能预先推测：没有真实拒绝依据的请求，或没有严格宽于当前模式的请求，会在不运行任何东西的情况下失败关闭，被拒绝的升权对该命令即为最终结果。
 
-工具持有自己的 `presentCall`/`presentResult` 渲染意图。前台调用是终端卡片，包含命令、说明、cwd、输出和解析后的退出状态。由于卡片以独立的 pill 展示退出状态，解析所消耗的 `[exit code: N]` / `[killed by signal: …]` 标记会从输出中移除；其他所有标记（截断、超时、沙箱）都保留在输出中。后台启动只返回 job id，因此使用通用执行卡片；通用 `job_*` 工具持有各自的卡片。这些 presenter 是纯函数，可安全回放。
+### 可能出什么问题
 
-## 工具仅使用具名参数构建请求
+没有执行器提供方的组合永远不会激活该工具。没有任务运行时的后台调用会以 `background jobs unavailable: load @deepseek-ai/dsh-jobs and @deepseek-ai/dsh-tool-jobs` 失败；没有沙箱执行器时的 `sandbox_permissions` 会以 `sandbox_permissions is not available in this composition (no sandboxing executor to escalate)` 失败。`enableRunInBackground: false` 会移除该参数，并在执行时拒绝强制后台调用。
 
-`ShellExecRequest` 携带可选的 `stdoutMaxBytes`、`stdin`、普通 `env` 和托管 `dshEnv`，供可信进程内插件及此工具的环境注册表使用。模型侧工具不公开 `stdoutMaxBytes`、`stdin` 或 `env`：它使用具名的命令／工作目录／超时／信号／沙箱字段，加上从注册表收集的 `dshEnv` 来构建请求。额外模型键会被忽略，无法替换托管值。Shell 语法可以提供等价的命令级行为，而本地执行器会清除环境中的凭据和陈旧 `DSH_*` 值。参见 [stdin/env Agent Note](../../../.agents/notes/implemented/architecture/2026-06-30-bash-stdin-env-trusted-plugin-api.zh.md)。
+-----
 
-## 权限与升权
+<a id="understand-the-implementation"></a>
+## 理解实现
 
-除非启用沙箱的执行器（[`dsh-bash-sandbox`](../bash-sandbox/)）限制命令，否则命令以执行器的完整权限运行。仅拒绝型沙箱会把拒绝作为结果事实报告，并在此渲染为拒绝标记；逐调用的允许／拒绝／询问策略由 `tools/pre-execute` waterfall（瀑布式事件）负责（参见 docs/architecture.md）。
+<details>
+<summary>实现细节——点击展开</summary>
 
-需要升权的 bash 调用会在执行前解析 `ctx.approval`。`allowed-once` 只对该次调用应用请求模式；审批被拒、取消、不可用或缺少审批上下文时，命令完全不会执行，并返回不同的错误。发生真实拒绝后，模型可以在同一轮次中使用满足需要的最窄模式和理由重试同一命令一次；审批提示本身就是征求同意的步骤。升权绝不能预先推测，禁用或拒绝审批即为最终结果。其理由见 [沙箱 Agent Note](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.zh.md)。
+本节解释工具背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
 
-## 逐会话模式切换
+### 设计理念
 
-对于启用沙箱的执行器，每次调用依次按单次升权、会话覆盖、执行器默认值解析模式。未启用沙箱以及没有 agent 的调用不携带会话覆盖。策略归属方贡献当前且不区分具体能力的常驻模式；拒绝结果仍负责特定于该操作的有效模式与重试引导。参见 [`dsh-shell` 折叠计算](../shell/README.zh.md)和[沙箱切换约定](../../../.agents/notes/implemented/feature/2026-07-06-sandbox.zh.md)。
+- **shell seam 的模型侧消费方。** 本工具是 bash 能力的 Consumer 角色：它注册 `bash` schema、渲染结果并解析每次调用的策略，进程机制归执行器 seam 所有。
+- **请求只来自命名参数。** 工具从不暴露 `stdin`、`env` 或 `stdoutMaxBytes`；它只用命令／workdir／超时／信号字段加上注册表收集的 `dshEnv` 构建每个请求，因此模型提供的键无法替换受管值（[bash stdin/env Agent Note](../../../.agents/notes/implemented/architecture/2026-06-30-bash-stdin-env-trusted-plugin-api.zh.md)）。
+- **非零退出只报告、不失败。** 只有基础设施故障（spawn 错误、中止）才会作为工具错误暴露；模型解读退出码与标记。
+- **后台工作归任务运行时。** 后台调用把进程句柄注册到 `ctx.jobs`；job id、所有权、完成通知与释放都是运行时的职责，本工具只把 bash 退出与沙箱事实映射为任务输出。

+
+### 请求解析
+
+工具在 `ctx.shell.resolve()` 运行前解析 workdir：显式的相对 `workdir` 相对会话 cwd 解析，沙箱策略的规范化 workspace root 优先，使约束与启动使用同一身份。沙箱策略通过 `ctx.sandboxPolicy` 按调用解析；升权请求在任何执行前经由 `ctx.approval`，若执行器会约束命令却没有挂载策略服务，工具在加载时失败。
+
+### 渲染故事
+
+结果文本为 stdout，然后是带标记的 `[stderr]` 区段，再是条件标记：截断通知、沙箱拒绝（组合声明升权时附带同轮次升权提示）、超时、信号与退出码——每个占一行。退出标记同时充当 UI 卡片的退出状态 pill：`dsh-shell` 共享的 `parseExitStatus` 会从输出体中消费它，因此回放显示 pill 而不重复标记。

-Model-facing `pwsh(command)` backed by one owner-scoped `ctx.terminals` shell. The package owns the tool contract and shell reuse; deployments select the terminal backend (a `terminal-bash` instance configured with `shellDialect: pwsh`) and sandbox policy. It is the Windows counterpart of `tool-bash-persistent`: same persistent-state contract, PowerShell dialect.
+## Summary
 
-## Config
+`dsh-tool-pwsh-persistent` gives the agent a `pwsh` tool whose PowerShell state persists across calls for the owning agent: cwd, `$env:` variables, functions, and background jobs survive between commands. It is the Windows counterpart of `dsh-tool-bash-persistent` — the same persistent-state contract in PowerShell dialect. Each agent gets its own shell backed by an owner-scoped PTY session with a pwsh-dialect backend, and commands for the same agent run one at a time. Configuration selects the backend and the wall-clock limit for one command; a timeout or an explicit `exit` closes the shell, and the next call starts fresh. Mount it with a pwsh-dialect terminal backend (Windows ConPTY or a POSIX pwsh) and the `ctx.terminals` service.
 
-| Key | Default | Meaning |
-|---|---:|---|
-| `backendType` | `shell` | Registered terminal backend used for each Agent shell. |
-| `timeoutMs` | `300000` | Wall-clock limit for one command; timeout closes the shell. |
-| `maxOutputChars` | `16000` | Maximum retained command-output characters; fixed diagnostics are added afterward. |
-| `description` | Persistent-shell description | Model-facing environment contract. |

+## Use this package
+
+Load this plugin in any composition where the agent should keep PowerShell state between commands — the persistent counterpart of `dsh-tool-pwsh` for work that needs cross-call state. It registers the `pwsh` tool and requires the `ctx.tools` and `ctx.terminals` services plus an owning agent session at execution time.
+
+### When to choose it
+
+Choose the persistent tool when work depends on cross-call PowerShell state, and choose `dsh-tool-pwsh` when every command should start from a known, clean environment. Commands that need interactive stdin are unsupported here — a foreground child that reads input blocks until the command timeout, which resets the shell — so interactive work belongs to the terminal tools.
+
+### Minimal configuration
+
+The default `shell` backend starts a PowerShell shell through a `dsh-terminal-bash` instance configured with `shellDialect: pwsh`; deployments may register another pwsh-dialect PTY backend and select it by name.
+
+```yaml
+- name: '@deepseek-ai/dsh-terminal'
+- name: '@deepseek-ai/dsh-terminal-bash'
+  config:
+    shellDialect: pwsh
+- name: '@deepseek-ai/dsh-tool-pwsh-persistent'
+```
+
+| Field | Default | Meaning |
+|---|---|---|
+| `backendType` | `shell` | Registered PTY backend used for each agent's shell |
+| `timeoutMs` | `300,000` | Wall-clock limit for one command; timeout closes the shell |
+| `maxOutputChars` | `16,000` | Maximum retained command-output characters; fixed diagnostics are added afterward |
+| `description` | `Run commands in a persistent PowerShell shell. State, including the current directory and exported environment variables, persists across calls for this agent.` | Model-facing environment contract; deployments may describe their environment |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-tool-pwsh-persistent) is the exhaustive source for every accepted field and its JSDoc.
+
+### What the agent can rely on
+
+Commands share one shell per agent, so cwd, `$env:` variables, functions, and background jobs persist across calls. Results exclude the private completion markers, the shell prompt, and the echoed input line. A non-zero wrapped command appends `[exit code: N]` — the exact native exit code when the command ran a native program, `1` for a terminating PowerShell error. A shell that exits before reporting that status instead appends `[shell exited: code N]`, `[shell killed by signal: SIG]`, or `[shell exited]` (Windows forced termination reports exit 1 without a signal), then resets and tells the agent the next call starts fresh. Long output keeps the earliest retained prefix plus a clipping notice; if the terminal has already dropped that prefix, the result says so explicitly.
+
+### What can go wrong
+
+A call without an owning agent session fails with `pwsh requires an owning agent session`, and a composition without a pwsh-dialect PTY backend activates the tool but fails its first call with `no PTY backend registered for "shell"`. A model redefinition of the `prompt` function removes the readiness marker, and the shell then settles on the silence tier instead of the marker fast path. Raw ESC characters inside a command are consumed by PSReadLine before execution and are unsupported. A timeout or cancellation closes the uncertain shell, discards the result, and reports the reset.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the tool and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+- **A deliberate twin of `dsh-tool-bash-persistent`.** The session registry, polling loop, and reset contract mirror the persistent bash tool by design ([pwsh persistent PTY Agent Note](../../../.agents/notes/implemented/architecture/2026-08-11-pwsh-persistent-pty.md)).
+- **Prompt-function readiness.** The tool installs its own `prompt` function that prints a BEL-terminated OSC marker plus a printable prompt; the OSC marker carries the last exit code and the printable prompt settles every command, so a model redefinition of `prompt` degrades readiness to the silence tier.
+- **PSReadLine echo stripped by anchoring.** PowerShell renders submitted input back into the stream; the marker-anchored extraction and a wrapper-source strip remove the echo, and a wrapper that wraps across the terminal width may leave a partial echo in partial-output results.
+- **Reset, never repair.** Any uncertain state — an explicit `exit`, a timeout, a send failure, an abort — closes the shell and starts the next call fresh.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: shell registry, prompt setup, command wrapping, scrollback polling, extraction and rendering |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; shell reuse is observable through tool execution) |
+
+### Command flow
+
+A first command spawns the shell through `ctx.terminals.spawn`, installs the `prompt` override, and waits for readiness. Each command is wrapped into one physical line — `Write-Output` of the start marker, the body escaped with backtick escapes into a double-quoted string, and `Write-Output` of the end marker plus the exit status — so PSReadLine's echo of a wrapped line cannot fabricate completion. The tool polls the scrollback in 1,000-line pages until the end marker or a completed prompt appears, extracts the span, strips the echoed wrapper and prompts, and renders it with any status marker. A timeout aborts the deadline, captures the partial output, and resets the shell.

 ## Known Limitations and Deferred Work
 
-- The tool requires an owning Agent and a real terminal backend with a pwsh dialect (Windows ConPTY or a POSIX pwsh).
-- **Input echo is unavoidable**: PowerShell's PSReadLine renders submitted input back into the terminal stream, and there is no `stty -echo` equivalent. The marker-anchored extraction excludes the echo in complete results; the wrapper-source strip covers fallback paths, but a wrapper that wraps across the terminal width may leave a partial echo in partial-output results, bounded by `maxOutputChars`.
-- Raw ESC characters inside model commands are unsupported: PSReadLine consumes them before execution. The wrapper escapes the control bytes it needs (`[char]27`-built OSC markers, backtick escapes for the body).
-- A model redefinition of the `prompt` function removes the readiness marker; the shell then settles on the silence tier instead of the marker fast path.
-- There is no interactive stdin during a command: a foreground command that reads input blocks until the readiness timeout, which resets the shell.
-- SIGTSTP/SIGHUP are unavailable on Windows (backend-rejected); SIGINT is delivered as a console-wide Ctrl-C input write, which at a prompt cancels the pending line instead of signalling a process.
-- Under the Windows ACL sandbox's read-only mode, pwsh starts in ConstrainedLanguage, which may deny the bootstrap's `[Console]::` encoding pin and prompt marker. Commands can still settle through the printable prompt and silence tier, but non-ASCII output may follow the host code page.

+## 使用本包
+
+在 agent 需要在命令之间保持 PowerShell 状态的任何组合中加载本插件——它是 `dsh-tool-pwsh` 的持久对应物，用于依赖跨调用状态的工作。它注册 `pwsh` 工具，需要 `ctx.tools` 与 `ctx.terminals` 服务，并在执行时需要拥有者 agent 会话。
+
+### 何时选择
+
+当工作依赖跨调用 PowerShell 状态时选择持久工具；当每条命令都应从已知、干净的环境开始时选择 `dsh-tool-pwsh`。这里不支持需要交互 stdin 的命令——读取输入的前台子进程会一直阻塞到命令超时，随后重置 shell——因此交互工作属于 terminal 工具。
+
+### 最小配置
+
+默认的 `shell` 后端通过配置了 `shellDialect: pwsh` 的 `dsh-terminal-bash` 实例启动 PowerShell shell；部署方可以注册其他 pwsh 方言 PTY 后端并按名称选择。
+
+```yaml
+- name: '@deepseek-ai/dsh-terminal'
+- name: '@deepseek-ai/dsh-terminal-bash'
+  config:
+    shellDialect: pwsh
+- name: '@deepseek-ai/dsh-tool-pwsh-persistent'
+```
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `backendType` | `shell` | 用于每个 agent shell 的已注册 PTY 后端 |
+| `timeoutMs` | `300,000` | 单条命令的墙钟上限；超时关闭 shell |
+| `maxOutputChars` | `16,000` | 保留的命令输出字符上限；固定诊断信息在其后追加 |
+| `description` | `Run commands in a persistent PowerShell shell. State, including the current directory and exported environment variables, persists across calls for this agent.` | 面向模型的环境约定；部署方可描述自己的环境 |
+
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-tool-pwsh-persistent)是每个受支持字段及其 JSDoc 的穷尽式真源。
+
+### agent 可以依赖什么
+
+命令共享每个 agent 一个 shell，因此 cwd、`$env:` 变量、函数与后台任务都会跨调用保留。结果排除私有完成标记、shell 提示词与回显的输入行。非零的包装命令追加 `[exit code: N]`——命令运行原生程序时给出确切原生退出码，PowerShell 终止错误则为 `1`。在报告该状态前就退出的 shell 改为追加 `[shell exited: code N]`、`[shell killed by signal: SIG]` 或 `[shell exited]`（Windows 强制终止报告 exit 1 且没有信号），然后重置并告诉 agent 下一次调用从全新状态开始。长输出保留最早的已保留前缀并附裁剪通知；若 terminal 已经丢弃该前缀，结果会明确说明。
+
+### 可能出什么问题
+
+没有拥有者 agent 会话的调用会以 `pwsh requires an owning agent session` 失败，没有 pwsh 方言 PTY 后端的组合会激活该工具，但首次调用以 `no PTY backend registered for "shell"` 失败。模型重定义 `prompt` 函数会移除就绪标记，shell 随后在静默层级而非标记快路径上结算。命令内的原始 ESC 字符会在执行前被 PSReadLine 消费，不受支持。超时或取消会关闭不确定的 shell、丢弃结果并报告重置。

+### 设计理念
+
+- **`dsh-tool-bash-persistent` 的刻意孪生。** 会话注册表、轮询循环与重置约定按设计镜像持久 bash 工具（[pwsh 持久 PTY Agent Note](../../../.agents/notes/implemented/architecture/2026-08-11-pwsh-persistent-pty.zh.md)）。
+- **prompt 函数就绪。** 工具安装自己的 `prompt` 函数，打印 BEL 结尾的 OSC 标记加可打印提示词；OSC 标记携带最后的退出码，可打印提示词让每条命令都能结算，因此模型重定义 `prompt` 会把就绪降级到静默层级。
+- **PSReadLine 回显靠锚定剥离。** PowerShell 会把提交的输入渲染回流中；标记锚定提取与包装源码剥离移除回显，而跨终端宽度换行的包装可能在部分输出结果中留下部分回显。
+- **重置，而非修复。** 任何不确定状态——显式 `exit`、超时、发送失败、中止——都会关闭 shell 并让下一次调用从全新状态开始。

+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；shell 复用可通过工具执行观察） |
+
+### 命令流程
+
+首条命令通过 `ctx.terminals.spawn` 生成 shell，安装 `prompt` 覆盖，并等待就绪。随后每条命令都包装成一行物理文本——`Write-Output` 起始标记、用反引号转义进双引号字符串的命令体、`Write-Output` 结束标记加退出状态——因此 PSReadLine 对换行包装的回显无法伪造完成。工具以 1,000 行一页轮询 scrollback，直到出现结束标记或完成的提示词，提取区间、剥离回显的包装与提示词，并连同任何状态标记一起渲染。超时会中止截止时间、捕获部分输出并重置 shell。

 # @deepseek-ai/dsh-tool-pwsh
 
 English | [中文](README.zh.md)
 
-The model-facing `pwsh` tool registered over the `ctx.shell` executor seam. Intended for Windows compositions where a PowerShell executor (e.g. `@deepseek-ai/dsh-pwsh-local`) backs `ctx.shell`; the tool contract is PowerShell-dialect: native `C:\...` paths and `$env:NAME` variables. Behavior mirrors `dsh-tool-bash` call-for-call — foreground and `run_in_background` execution through the generic job runtime, the managed `DSH_*` environment through the shared `shell-env` registry, the sandbox denial rendering with the same-turn `sandbox_permissions` escalation surface, and the bash marker/truncation rendering story (a clean exit produces no marker).
+## Summary
 
-Requires a loaded executor implementation and the `shell-env` plugin; the tool stays pending until both exist (`inject: ['tools', 'bash', 'systemPrompt', 'bashEnv']`).
+`dsh-tool-pwsh` gives the agent a `pwsh` tool that runs PowerShell commands through the mounted shell executor — the Windows counterpart of `dsh-tool-bash`, mirroring it call-for-call. Each call runs in a fresh pwsh process, so no state survives; `run_in_background` turns long-running commands into background jobs. Commands are PowerShell-dialect: native `C:\...` paths and `$env:NAME` variables, with no dialect translation. Every call runs with the managed `DSH_*` environment, and under a sandboxing executor the tool teaches and enforces the Windows-specific language-mode and named-pipe contracts. Mount it with a PowerShell executor such as `dsh-pwsh-local` and the `dsh-shell-env` plugin.
 
-The package root exposes only the Cordis plugin contract (`name`, `inject`, `Config`, `apply`); result rendering (`src/render.ts`) and background-job adaptation (`src/background.ts`) mirror the bash tool's structure and stay reachable through the package's `./src/*` export.
+## Table of Contents
 
-The plugin also contributes the `tool:pwsh` prompt section (first-party order 1010): non-zero exits are reported as `[exit code: N]` markers, and Windows interruption settles as exit 1 without a signal marker.

+## Use this package
 
-| Arg | Type | Notes |
+Load this plugin in any composition where the agent should run PowerShell commands — typically a Windows composition whose `ctx.shell` is backed by a PowerShell executor. It registers the `pwsh` tool once the executor provider and the `dsh-shell-env` registry are mounted.
+
+### When to choose it
+
+Choose the pwsh tool when commands must be written in PowerShell — native paths and `$env:` variables — or when the deployment is Windows-native. Choose `dsh-tool-bash` when the command set is bash-dialect; there is no translation between the two. When work needs cross-call state (cwd, variables), the persistent counterpart [`dsh-tool-pwsh-persistent`](../tool-pwsh-persistent/README.md) keeps one owner-scoped shell alive.
+
+### Minimal configuration
+
+The common path is a PowerShell executor provider, the environment registry, and this tool.
+
+```yaml
+- name: '@deepseek-ai/dsh-pwsh-local'
+- name: '@deepseek-ai/dsh-shell-env'
+- name: '@deepseek-ai/dsh-tool-pwsh'
+```
+
+The single config field toggles background support.
+
+| Field | Default | Meaning |
 |---|---|---|
-| `command` | string (required) | Run via `pwsh -Command`. No state persists between calls — use `workdir`, not `cd`. |
-| `description` | string (required) | One-line, active-voice summary of the command (5-10 words), for UI/log display only — no effect on execution. |
-| `timeoutMs` | number | Timeout override in milliseconds. The executor applies its configured default and cap. |
-| `workdir` | string | Working directory for this call. Defaults to the calling agent's session cwd (`session.header.cwd`) so each session runs in its own workspace; a relative `workdir` is resolved against that same identity. |
-| `run_in_background` | boolean | Return a job id immediately; no timeout applies. |
-| `sandbox_permissions` | string enum | Advertised only when a sandboxing executor is mounted (`ctx.shell.sandboxMode` defined). The wider sandbox mode for a one-shot retry of a command the sandbox just denied — the narrowest wider mode that suffices, requiring `justification` and user approval through `ctx.approval` BEFORE execution. A non-widening or unapprovable request fails closed without running anything. |
-| `justification` | string | Required with `sandbox_permissions`: one sentence for the user explaining why this exact command needs the wider access. |
+| `enableRunInBackground` | `true` | Expose `run_in_background`; when `false`, forced background calls are rejected |
 
-`command`, `workdir`, and `timeoutMs` are resolved against the executor's config defaults via `ctx.shell.resolve()` before execution. The workdir default is applied in the tool layer from the calling agent's `session.header.cwd` BEFORE `resolve()` — the per-session cwd must come from `exec.agent`, since N sessions share one executor; only when no session cwd is available does the executor fall back to its own config / `process.cwd()`.
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-tool-pwsh) is the exhaustive source for every accepted field and its JSDoc; the generated [tool catalog](../../../docs/tool-catalog.md#deepseek-aidsh-tool-pwsh) carries the full argument schema.
 
-### Managed shell environment
+### Running a command
 
-Every foreground and background model pwsh call receives a freshly collected trusted `DSH_*` environment through the shared [`dsh-shell-env`](../shell-env/) registry: `DSH_HOME` (the absolute Harness home), `DSH_SHELL=1`, the agent's `DSH_SESSION_ID`, and `DSH_SESSION_JSONL` when the active persistence backend locates one. Plugins contributing `DSH_*` facts to `ctx.shellEnv` apply to pwsh calls exactly as they do to bash calls. The snapshot passes through the dedicated `ShellExecRequest.dshEnv` channel; `process.env` is never modified. The description teaches the generic `$env:DSH_*` convention rather than naming persistence-specific variables.
+The tool executes `pwsh -Command <command>` and returns the combined output. Commands run in a fresh pwsh process every call, so state never persists — pass `workdir` instead of `cd`. Paths use native Windows form and environment variables are read with `$env:NAME`. A non-zero exit is reported as `[exit code: N]`; on Windows a force-killed command settles as `[exit code: 1]` without a signal marker, so the agent treats a bare exit 1 after an interruption as a termination, not a command failure. Background runs, output truncation, and the `description`/`timeoutMs`/`workdir` arguments behave exactly as in `dsh-tool-bash`.
 
-Result text contains stdout, an optional `[stderr]` section, then applicable truncation, sandbox-denial (with the same-turn escalation hint when the composition advertises escalation), timeout, signal, and exit markers. A clean exit (0, no signal) produces no marker; an empty body renders as `(no output)`. Truncation links a safe complete spill file or reports it unavailable. Timeout is reported independently of final exit status; nonzero exit remains a model-interpreted result rather than `isError`. Windows reports forced termination as exit 1 without a signal, so `[killed by signal: …]` is POSIX-only there. Only infrastructure failures — spawn errors and aborts (`tool call aborted`) — produce `isError`.
+### Windows-specific sandbox behavior
 
-The canonical success is `{ kind: 'foreground', ...ShellRunResult }` for a completed foreground process (with the executor's `sandbox` facts — `mode`/`denied`, optional `enforcement`/`runnerFailed` — projected when present) or `{ kind: 'background', jobId }` for a published task. The renderer preserves exactly `started background job <id>` for background acks; programmatic consumers use the typed fields without parsing the rendered text.
+Under a sandboxing executor, denied commands report `[sandbox: file access denied under <mode> mode]`, and the same one-shot escalation path applies: retry the exact command once with `sandbox_permissions` plus a `justification` through user approval. The tool also teaches two Windows-restricted-token contracts in its description: read-only pwsh runs in ConstrainedLanguage (`.NET` static calls, `Add-Type`, COM, and reflection fail with "only core types" errors), and in both confined modes programs cannot open named pipes, so a command that captures another program's output through piped stdio fails with EPERM — escalate the exact command once or restructure it to avoid capturing output.
 
-When `run_in_background` is true, this plugin preflights `ctx.jobs.start()` before spawning, registers the calling agent as owner, and adapts the returned `ShellProcess` handle into generic cancel/done/incremental-output hooks. The job runtime owns ids, cross-session isolation, completion notices, waiting, and disposal cleanup; this plugin only maps pwsh exit facts into job output and outcome detail. `enableRunInBackground: false` removes the parameter and rejects a forced background call at execution time.
+### What can go wrong
 
-## UI presentation
+A composition with no PowerShell executor never activates the tool, and the injected services (`tools`, `shell`, `systemPrompt`, `shellEnv`) must all exist. Background calls without the job runtime fail with `background jobs unavailable: load @deepseek-ai/dsh-jobs and @deepseek-ai/dsh-tool-jobs`, and `sandbox_permissions` without a sandboxing executor fails with `sandbox_permissions is not available in this composition (no sandboxing executor to escalate)`.
 
-The tool owns its `presentCall`/`presentResult` render intent. A foreground call is a `terminal` card carrying command, description, and optional cwd; a `run_in_background` call is a `generic` card with the raw command, mirroring the bash tool's background presentation. A completed foreground result is a `terminal` card too: the exit marker becomes the card's exit-status pill (`exitCode`/`signal`), and the marker-free body is the card's output — exactly the bash tool's terminal-card story, via the shared exit-status parse from `@deepseek-ai/dsh-shell`. Background acks and execution errors stay `generic` cards with the rendered output in a `console` fence. These presenters are pure and replay-safe.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the tool and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+- **A deliberate twin of `dsh-tool-bash`.** Foreground and background execution, the managed environment, the sandbox escalation surface, and the marker/truncation rendering mirror the bash tool call-for-call, so consumers of one accept the other's wire shape ([pwsh tool and executor Agent Note](../../../.agents/notes/implemented/feature/2026-08-01-pwsh-tool-and-executor.md)).
+- **PowerShell-dialect contract.** The tool contract is PowerShell: native paths and `$env:` variables, executed via `pwsh -Command` with no intermediate shell.
+- **Windows sandbox facts taught in the description.** The ConstrainedLanguage and named-pipe contracts are Windows-restricted-token behavior; the gate for teaching them is "any confining executor is mounted", which is safe because every shipped pairing is win32-only.
+- **Non-zero exits are reported, not errored.** Only infrastructure failures (spawn errors, aborts) surface as tool errors, matching the bash story.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: tool registration, prompt section, arg validation, escalation, request assembly |
+| [`src/background.ts`](src/background.ts) | Map a settled background process onto generic job outcome vocabulary |
+| [`src/render.ts`](src/render.ts) | Model-facing result text: streams, markers, truncation notices (bash twin) |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; execution relations are owned by the capability seam) |
+
+### Rendering and exit markers
+
+The renderer shares the bash tool's structure and the `parseExitStatus` marker contract from `dsh-shell`: a clean exit (0, no signal) produces no marker; the UI card consumes the exit marker as its exit-status pill. Windows forced termination settles as exit 1 without a signal, so `[killed by signal: …]` is POSIX-only there. The `tool:pwsh` prompt section (first-party order 1010) teaches the exit-marker convention and the Windows exit-1-after-interruption reading.

+These limits define when the tool is a poor fit or needs special care. They are current package constraints, not a task backlog.
+
 - **Language mode and named-pipe capture under the Windows sandbox** — under the [Windows ACL sandbox](../../sandbox/sandbox-windows-acl/README.md), read-only pwsh starts in ConstrainedLanguage because its temp write denial makes PowerShell's AppLocker probe fail closed: `Add-Type`, non-core .NET statics (`[System.IO.*]::`, `[math]::`), COM objects, and reflection fail with "only core types" errors, and the mode cannot be lifted from inside. Workspace-write's private temp lets the probe complete, so it stays in FullLanguage unless host policy says otherwise. Both confined modes deny named-pipe opens, so a piped-stdio spawn inside a confined command fails with EPERM. The tool description teaches both contracts to the model; the backend README owns the full limitations.
-- **No persistent shell** — every call starts a fresh `pwsh -Command`; the persistent-shell counterpart is [`@deepseek-ai/dsh-tool-pwsh-persistent`](../tool-pwsh-persistent/README.md), which keeps one owner-scoped pwsh alive across calls on Windows (ConPTY) and POSIX hosts with pwsh.

 - **PowerShell-dialect contract** — the model must write PowerShell (native paths, `$env:` variables), not bash; there is no dialect translation.
 - **Session-cwd identity is not canonicalized** — the workdir base is the session header cwd as-is, unlike the bash tool's sandbox-root-canonicalized identity. Under a confining executor the policy's workspace root IS canonicalized (by the shared policy service), so the workdir and the confinement root can diverge when the raw session cwd differs from its canonical form — a parity gap deferred to the shared shell-tool base extraction.

 [English](README.md) | 中文
 
-注册在 `ctx.shell` 执行器 seam 之上的面向模型的 `pwsh` 工具。面向由 PowerShell 执行器（如 `@deepseek-ai/dsh-pwsh-local`）支撑 `ctx.shell` 的 Windows 组合；工具约定是 PowerShell 方言：原生 `C:\...` 路径与 `$env:NAME` 变量。行为与 `dsh-tool-bash` 逐调用对齐——通过通用任务运行时执行前台与 `run_in_background`、通过共享 `shell-env` 注册表管理 `DSH_*` 环境、sandbox 拒绝渲染与同轮次 `sandbox_permissions` 升级面、以及 bash 的 marker/截断渲染故事（干净退出不产生 marker）。
+## 概述
 
-需要已加载的执行器实现与 `shell-env` 插件；两者都存在前工具保持 pending（`inject: ['tools', 'bash', 'systemPrompt', 'bashEnv']`）。
+`dsh-tool-pwsh` 为 agent 提供 `pwsh` 工具，通过已挂载的 shell 执行器运行 PowerShell 命令——它是 `dsh-tool-bash` 的 Windows 对应物，逐调用镜像。每次调用都运行在全新 pwsh 进程中，因此状态不会保留；`run_in_background` 把长时间运行的命令变成后台任务。命令是 PowerShell 方言：原生 `C:\...` 路径与 `$env:NAME` 变量，不做方言翻译。每次调用都运行在受管 `DSH_*` 环境中；在沙箱执行器下，工具会教授并执行 Windows 特有的语言模式与命名管道约定。请与 `dsh-pwsh-local` 等 PowerShell 执行器以及 `dsh-shell-env` 插件一起挂载。
 
-包根只导出 Cordis 插件约定（`name`、`inject`、`Config`、`apply`）；结果渲染（`src/render.ts`）与后台任务适配（`src/background.ts`）镜像 bash 工具的结构，并可通过包的 `./src/*` 导出访问。
+## 目录
 
-插件还贡献 `tool:pwsh` 提示词段落（first-party 顺序 1010）：非零退出以 `[exit code: N]` marker 报告，Windows 上的中断以无 signal 的 exit 1 结算。

+## 使用本包
 
-| Arg | Type | Notes |
+在 agent 需要运行 PowerShell 命令的任何组合中加载本插件——通常是 `ctx.shell` 由 PowerShell 执行器支撑的 Windows 组合。一旦挂载执行器提供方与 `dsh-shell-env` 注册表，它就注册 `pwsh` 工具。
+
+### 何时选择
+
+当命令必须用 PowerShell 编写——原生路径与 `$env:` 变量——或部署是 Windows 原生时，选择 pwsh 工具。当命令集是 bash 方言时选择 `dsh-tool-bash`；两者之间没有翻译。当工作依赖跨调用状态（cwd、变量）时，持久对应物 [`dsh-tool-pwsh-persistent`](../tool-pwsh-persistent/README.zh.md) 会保持一个按所有者隔离的 shell 存活。
+
+### 最小配置
+
+常用路径是 PowerShell 执行器提供方、环境注册表与本工具。
+
+```yaml
+- name: '@deepseek-ai/dsh-pwsh-local'
+- name: '@deepseek-ai/dsh-shell-env'
+- name: '@deepseek-ai/dsh-tool-pwsh'
+```
+
+唯一的配置字段用于开关后台支持。
+
+| 字段 | 默认值 | 含义 |
 |---|---|---|
-| `command` | string (required) | 通过 `pwsh -Command` 运行。调用之间不保留状态——用 `workdir`，不要用 `cd`。 |
-| `description` | string (required) | 命令的一行主动语态摘要（5-10 词），仅用于 UI/日志展示——不影响执行。 |
-| `timeoutMs` | number | 超时覆盖值（毫秒）。执行器应用其配置的默认值与上限。 |
-| `workdir` | string | 本次调用的工作目录。默认取调用 agent（智能体）的会话 cwd（`session.header.cwd`），使每个会话在自己的工作区运行；相对 `workdir` 基于同一身份解析。 |
-| `run_in_background` | boolean | 立即返回 job id；不适用超时。 |
-| `sandbox_permissions` | string enum | 仅当已挂载 sandbox 执行器时才会公开（`ctx.shell.sandboxMode` 已定义）。用于对刚被 sandbox 拒绝的命令做一次性重试的更宽 sandbox 模式——取刚好足够的最窄更宽模式，要求 `justification` 并在执行**之前**经 `ctx.approval` 获得用户批准。未拓宽或无法获批的请求 fail-closed，不运行任何内容。 |
-| `justification` | string | 必须与 `sandbox_permissions` 一同提供：用一句话向用户解释为何正是这条命令需要更宽的访问。 |
+| `enableRunInBackground` | `true` | 暴露 `run_in_background`；为 `false` 时拒绝强制后台调用 |
 
-`command`、`workdir` 与 `timeoutMs` 在执行前经 `ctx.shell.resolve()` 按执行器配置默认值解析。workdir 默认值在工具层于 `resolve()` 之前从调用 agent 的 `session.header.cwd` 取得——每次会话的 cwd 必须来自 `exec.agent`，因为 N 个会话共享一个执行器；仅当没有会话 cwd 时执行器才回退到自己的配置 / `process.cwd()`。
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-tool-pwsh)是每个受支持字段及其 JSDoc 的穷尽式真源；生成的[工具目录](../../../docs/tool-catalog.zh.md#deepseek-aidsh-tool-pwsh)携带完整参数 schema。
 
-### Managed shell environment
+### 运行命令
 
-每次前台与后台模型 pwsh 调用都会通过共享的 [`dsh-shell-env`](../shell-env/) 注册表收到一份新收集的受信任 `DSH_*` 环境：`DSH_HOME`（Harness 主目录绝对路径）、`DSH_SHELL=1`、agent 的 `DSH_SESSION_ID`，以及活跃持久化后端定位到 JSONL 时的 `DSH_SESSION_JSONL`。向 `ctx.shellEnv` 贡献 `DSH_*` 事实的插件对 pwsh 调用与 bash 调用一视同仁。快照通过专用的 `ShellExecRequest.dshEnv` 通道传递；`process.env` 永不被修改。描述只教授通用的 `$env:DSH_*` 约定，而不是点名持久化相关的变量。
+工具执行 `pwsh -Command <command>` 并返回合并后的输出。命令每次调用都运行在全新 pwsh 进程中，因此状态从不保留——请传 `workdir` 而不是 `cd`。路径使用原生 Windows 形式，环境变量用 `$env:NAME` 读取。非零退出以 `[exit code: N]` 报告；在 Windows 上，强制终止的命令以 `[exit code: 1]` 结算且没有信号标记，因此 agent 把中断后的裸 exit 1 当作终止而非命令失败。后台运行、输出截断以及 `description`／`timeoutMs`／`workdir` 参数的行为与 `dsh-tool-bash` 完全一致。
 
-结果文本包含 stdout、可选的 `[stderr]` 段，然后是适用的截断、sandbox 拒绝（组合公开升级能力时带同轮次升级提示）、超时、signal 与退出 marker。干净退出（0、无 signal）不产生 marker；空体渲染为 `(no output)`。截断会链接一个安全的完整 spill 文件，或报告其不可用。超时独立于最终退出状态报告；非零退出仍是模型解读的结果而非 `isError`。Windows 上强制终止以无 signal 的 exit 1 结算，因此 `[killed by signal: …]` 仅适用于 POSIX。只有基础设施失败——spawn 错误与中止（`tool call aborted`）——产生 `isError`。
+### Windows 特有的沙箱行为
 
-规范成功形态是已完成前台进程的 `{ kind: 'foreground', ...ShellRunResult }`（存在时投影执行器的 `sandbox` 事实——`mode`/`denied`、可选的 `enforcement`/`runnerFailed`）或已发布任务的 `{ kind: 'background', jobId }`。渲染器对后台 ack 精确保留 `started background job <id>`；编程消费者使用类型化字段而不解析渲染文本。
+在沙箱执行器下，被拒绝的命令会报告 `[sandbox: file access denied under <mode> mode]`，并适用相同的单次升权路径：用 `sandbox_permissions` 加一句 `justification`，经用户审批后重试完全相同的命令一次。工具还会在其描述中教授两条 Windows 受限令牌约定：只读 pwsh 运行在 ConstrainedLanguage 中（`.NET` 静态调用、`Add-Type`、COM 与反射会以 "only core types" 错误失败）；两种受限模式下程序都无法打开命名管道，因此通过管道 stdio 捕获另一程序输出的命令会以 EPERM 失败——请升权该确切命令一次，或重构命令以避免捕获输出。
 
-当 `run_in_background` 为 true 时，本插件在 spawn 前预检 `ctx.jobs.start()`，把调用 agent 注册为 owner，并将返回的 `ShellProcess` 句柄适配为通用的 cancel/done/增量输出钩子。任务运行时负责 job id、跨会话隔离、完成通知、等待和 dispose（资源释放）清理；本插件只把 pwsh 退出事实映射进任务输出与结果明细。`enableRunInBackground: false` 会移除参数并在执行时拒绝强制的后台调用。
+### 可能出什么问题
 
-## UI presentation
+没有 PowerShell 执行器的组合永远不会激活该工具，且注入的服务（`tools`、`shell`、`systemPrompt`、`shellEnv`）必须全部存在。没有任务运行时的后台调用会以 `background jobs unavailable: load @deepseek-ai/dsh-jobs and @deepseek-ai/dsh-tool-jobs` 失败；没有沙箱执行器时的 `sandbox_permissions` 会以 `sandbox_permissions is not available in this composition (no sandboxing executor to escalate)` 失败。
 
-工具拥有自己的 `presentCall`/`presentResult` 呈现意图。前台调用是携带命令、描述与可选 cwd 的 `terminal` 卡；`run_in_background` 调用是携带原始命令的 `generic` 卡，镜像 bash 工具的后台呈现。完成的前台结果同样是 `terminal` 卡：退出 marker 变成卡片的退出状态 pill（`exitCode`/`signal`），去 marker 的正文成为卡片输出——与 bash 工具的 terminal 卡故事完全一致，经由 `@deepseek-ai/dsh-shell` 的共享退出状态解析。后台 ack 与执行错误保持 `generic` 卡，以 `console` 围栏包裹渲染输出。这些 presenter 是纯函数且可重放。

 # skill/ — skill capability family
 
 English | [中文](README.zh.md)
 
-This family discovers reusable agent instructions and exposes them to the model through a provider-neutral catalog and loader.
+## Summary
+
+The skill group gives agents and users access to reusable, task-specific instructions on demand. Providers contribute skills — from local project or user directories, bundled packages, or remote services — and the registry merges their catalogs and resolves the winning skill for each name. A consumer publishes the available skills as a durable session catalog and exposes a model-facing `skill` loader tool, so the model sees sorted skill names and descriptions and can load the full instructions of any listed skill; users can also invoke a skill directly with `/name`. Provider type does not change what the model sees, because all model-facing rendering lives in one consumer package. Mount the packages you need: the registry plus at least one provider, and the consumer for model access.

+skill 组让 agent（智能体）和用户按需使用可复用的任务专项指令。提供方贡献 skill——来自本地项目或用户目录、随包分发或远程服务——注册表合并它们的目录，并为每个名称解析出胜出的 skill。一个消费方把可用 skill 发布为持久的会话目录，并提供面向模型的 `skill` 加载工具，因此模型看到排序后的 skill 名称与简短描述，并能加载任一列出 skill 的完整指令；用户也可以用 `/name` 直接调用 skill。提供方类型不会改变模型看到的内容，因为所有面向模型的渲染都集中在一个消费方包中。按需挂载各包：注册表加至少一个提供方，再加消费方以获得模型访问。

-Optional bundled skill provider that contributes `dsh-badge` to `ctx.skills`. The skill supplies the official “powered by dsh” Markdown snippets and the packaged PNG for systems that cannot import a remote image reliably.
+## Summary
 
-Mount the plugin to enable the provider. It has no configuration. The shipped CLI composition includes the plugin as `disabled: true`; users must explicitly enable its `skill-badge` row before the skill enters a catalog.
+Agents can load the official "powered by dsh" badge skill from this bundled provider and follow its instructions for adding attribution badges to documents, pull requests, and other content produced with DeepSeek Harness. The provider has no configuration, and the shipped CLI composition includes the plugin disabled, so deployments enable it explicitly. The skill ships both Markdown snippets and a packaged PNG for systems that cannot reliably import remote images.
 
-The provider exposes its packaged `assets/` directory as the skill resource base. `dsh-badge.png` is the 726×120 source asset, and consumers render it at 121×20.

+## Use this package
+
+Enable the plugin to make the `dsh-badge` skill available in the session skill catalog; the model can then load it like any other skill and follow its instructions for adding a "powered by dsh" badge.
+
+### When to choose it
+
+Choose this provider when content produced with DeepSeek Harness should carry official attribution badges, and the deployment wants the badge skill available to agents without storing it in a local skill directory. Skip it when the badge is irrelevant to the deployment — the plugin is disabled by default and adds nothing until enabled.
+
+### Enable the plugin
+
+The plugin has no configuration. Add its composition row to a composition; the shipped CLI composition carries the row as `disabled: true`, so enable it explicitly there.
+
+```yaml
+- name: '@deepseek-ai/dsh-skill-badge'
+```
+
+After enabling, `dsh-badge` appears in the available skills of the session catalog. The skill covers remote Markdown badges (Shields.io-based) and a packaged PNG badge asset for targets that cannot fetch remote images reliably.
+
+### What the badge skill provides
+
+- **Markdown snippets.** Instructions for embedding the official badge markup in documents, pull requests, and merge requests.
+- **Packaged PNG asset.** A `dsh-badge.png` resource (726×120 source, rendered at 121×20) that works where remote images cannot be imported.
+
+### Observable success and failures
+
+Enabling the plugin makes `dsh-badge` appear in the catalog and loadable by name; disabling or omitting the row keeps it out of every catalog. Because the provider is immutable, discovery always succeeds with exactly one skill and never reports partial results.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the bundled provider is wired; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The provider is an immutable, synchronously registered skill source: it registers one fixed candidate at the bundled skill rank (600) under the provider name `dsh-badge`, exposes its packaged `assets/` directory as the skill's directory resource base, and reads the skill body from the packaged `assets/dsh-badge.md` file on every load.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry and the immutable provider: one candidate, resource base, body load |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion |
+| [`assets/`](assets/) | Packaged skill body (`dsh-badge.md`) and PNG asset (`dsh-badge.png`) |

-Local filesystem provider for the `ctx.skills` registry.
+## Summary
 
-This package implements one skill source. It scans local project, custom, and user skill roots, parses `SKILL.md` or flat Markdown skill files, and registers the provider on `ctx.skills`. The registry remains in `@deepseek-ai/dsh-skill`; the durable session catalogs and model-facing loader tool remain in `@deepseek-ai/dsh-tool-skill`.
+Agents can use local skills from the repository, a custom directory, or the user's agent configuration: author a skill as a directory bundle with a `SKILL.md` or a flat `<name>.md` file under any scanned root, and it appears in the session catalog. The provider discovers the project, custom, and user roots, parses each skill's YAML frontmatter, and watches the directories, so new, renamed, or deleted skills reach agents without a restart. Choose it when skills live on disk — the registry (`dsh-skill`) accepts any provider, and another provider can supply skills from elsewhere.

+## Use this package
 
-## Discovery
+Mount the plugin to make local skills available to agents. It scans the project, custom, and user skill roots below, parses each skill's frontmatter into a catalog entry, and loads the body on demand; it also watches the roots so new, renamed, or deleted skills reach the next catalog without a restart.
 
-Default roots are resolved in this provider's rank order:
+### When to choose it
+
+Use this provider when skills live on disk — in the repository, a custom directory, or the user's agent configuration. Avoid it when skills come from a remote registry or embedded plugin data: the registry accepts any provider, and this package is one implementation.
+
+### Skill format
+
+A skill is either a directory bundle `<name>/SKILL.md` or a flat file `<name>.md` at the top level of a scanned root; nested `**/SKILL.md` files are deliberately not discovered. The file starts with YAML frontmatter: required `name` and `description`, plus optional `whenToUse`, `metadata`, `disable-model-invocation`, and `user-invocable`.
+
+`disable-model-invocation: true` keeps the skill out of model-facing catalogs and loaders; `user-invocable: false` keeps it out of human-facing commands, and omitted fields default to permitting their surface. The two keys accept YAML booleans plus the case-insensitive `true`/`false`, `yes`/`no`, `on`/`off`, and `1`/`0` forms; a rejected spelling or a non-boolean value drops the whole skill with a warning rather than silently permitting a surface.
+
+The catalog and the body have separate lifecycles: discovery parses frontmatter into the catalog entry, and every load re-reads the current file, so editing a skill body needs no versioning or cache invalidation.

-The project root is the nearest ancestor containing `.git`; without one, the current cwd is used. The user DSH root skips its `.system` child so system-owned directories are not treated as normal user skills. `includeDefaultRoots: false` omits the project and user rows and the `$DSH_BUNDLED_SKILL_DIR` environment default while retaining explicitly configured custom and bundled roots, allowing several uniquely named isolated providers to see only their own roots. This provider supplies project and user skills; another provider may supply built-in system skills.
+The project root is the nearest ancestor containing `.git`; without one, the current cwd is used. The user DSH root skips its `.system` child. `includeDefaultRoots: false` omits the project and user rows plus the `$DSH_BUNDLED_SKILL_DIR` default so an isolated provider sees only its own configured roots; `bundledSkillDir` adds a bundled root at rank 600.
 
-When `ctx.fs` is available, discovery lists roots through `ctx.fs.listDir`, reads skill files through `ctx.fs.readText`, and probes `.git` through the filesystem service. Full skill loads forward the lookup abort signal to filesystem metadata and content reads. Without a filesystem service, the provider falls back to abortable Node filesystem I/O so minimal local contexts can still load skills. Confirmed missing paths are valid empty state, malformed or non-text entries warn and skip, and unexpected discovery/read failures make the registry snapshot incomplete rather than replacing a last-good model catalog with a misleading deletion.
+### Mount and configure
 
-## Catalog Change Detection
+Load the plugin alongside the skill registry; it requires `ctx.skills`.
 
-Existing skill roots are watched with Chokidar. Before opening a native watcher, the provider realpaths the existing root or ancestor and restores the next missing segment; when `watchFollowSymlinks` is false and the root itself is a symbolic link, it preserves that final link so Chokidar can enforce the configured boundary. Discovery and diagnostics retain the configured path, while Windows cannot otherwise mix an 8.3 alias with long-form libuv events. The provider observes direct bundle directory additions/removals, flat Markdown additions/removals, and direct `SKILL.md` additions/removals/changes; `change` exists to rediscover catalog frontmatter such as `name` and `description`. Changes below `references`, `scripts`, `assets`, or other bundle resources do not invalidate the catalog. Events delivered in the same microtask batch collapse to one provider invalidation.
+```yaml
+- name: '@deepseek-ai/dsh-skill'
+- name: '@deepseek-ai/dsh-skill-filesystem'
+```
 
-A root that does not exist is followed from the nearest existing ancestor one missing path segment at a time. The next segment is probed with `fs.watchFile`; once `.agents`, `skills`, or the configured root appears, observation advances until Chokidar can attach to the real root. Root deletion reverses this process, so deleting and recreating an entire skills directory remains observable. Project-scoped watchers are bounded by `watchMaxProjects`; revisiting an evicted project reattaches observation during discovery.
+| Field | Default | Meaning |
+|---|---|---|
+| `providerName` | `filesystem` | Unique provider name registered on `ctx.skills` |
+| `includeDefaultRoots` | `true` | Include project and user roots around `customSkillDirs` |
+| `dshHome` | `$DSH_HOME` or `~/.dsh` | Harness config root; its `skills` subdirectory is scanned |
+| `agentsHome` | `$DSH_AGENTS_HOME` or `~/.agents` | Shared agent config root scanned for compatible skills |

+| `bundledSkillDir` | — | Bundled skill root scanned at rank 600 when configured |
 
-The first-party filesystem `write` and `edit` tools also synchronously invalidate the provider through `fs/observed` when their target could affect a watched skill entry. This fast path makes the next model step observe its own filesystem mutation without waiting for the host watcher. External IDE, Git, shell, and process changes rely on Chokidar or the missing-path probe. Existing-root watchers remain persistent until effect teardown so Chokidar owns asynchronous native error events; startup/runtime watcher failures are logged and retried. Discovery still scans readable roots and returns their candidates for direct loading, but marks the observation incomplete so it is not cached or published as an authoritative model catalog. Effect teardown closes every watcher and contains late callbacks.
+The remaining `watch*` fields tune Chokidar behavior — polling, stability window, interval, project cap, and symlink following. The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-skill-filesystem) is the exhaustive source for every field.
 
-## Skill Format
+### Change detection
 
-Skills can be single-level directory bundles (`<name>/SKILL.md`) or flat Markdown files (`<name>.md`). Nested `**/SKILL.md` discovery is deliberately excluded. Frontmatter is parsed as an open YAML object with the `yaml` package; this provider interprets required `name` and `description`, plus optional `whenToUse`, `metadata`, `disable-model-invocation`, and `user-invocable`. Names must be kebab-case.
+Existing roots are watched, so adding, renaming, or deleting a skill (or editing its frontmatter) triggers a catalog refresh for the next model step; edits below `references`, `scripts`, `assets`, and other bundle resources do not. The first-party `write` and `edit` tools invalidate the provider directly when their target could affect a watched skill, so the model observes its own filesystem mutation without waiting for the host watcher. External IDE, Git, and shell changes are picked up by the host watcher, and a root that does not exist yet is probed until it appears.
 
-The two invocation fields accept YAML booleans and the case-insensitive forms `true`/`false`, `yes`/`no`, `on`/`off`, and `1`/`0`. `disable-model-invocation: true` excludes the skill from model-facing catalogs and loaders; `user-invocable: false` excludes it from human-facing commands. Each omitted field defaults to permitting its surface, and the provider always emits both positive internal policy values, including when both keys are absent. A rejected camel-case spelling or a non-boolean invocation value drops the entire skill from discovery with a warning instead of discarding only that field or falling back to a permissive default. Invocation policy fails closed because ignoring invalid data could expose a skill on a disabled surface; wrong-typed optional `whenToUse` and `metadata` values are omitted because neither currently grants invocation.
+### Observable success and failures
 
-The catalog and body have separate lifecycles. Discovery parses frontmatter to produce the summary. Every `skill(name)` load rereads and reparses the current file, so body edits need no hash, revision, cache invalidation, or proactive model notification. A frontmatter rename between discovery and loading rejects the stale name and invalidates the provider; the next catalog observation publishes the new name.
+A valid skill under any scanned root appears in the session catalog sorted by name, and loading it returns the current file body. A file without valid frontmatter, an invalid name, or an invalid invocation value is skipped with a warning, so the model catalog receives no per-skill diagnostic and cannot distinguish an absent skill from an invalid one. Unexpected discovery or read failures leave the catalog observation incomplete rather than replacing the last-good view with a misleading deletion.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how discovery and watching are organized; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The provider is built on two separations. First, catalog versus body: discovery parses frontmatter into summaries, while every load re-reads the file, so body edits need no hash, revision, or cache invalidation. Second, discovery versus watching: `list()` scans roots and resolves the project root through `ctx.fs` when a filesystem service is present (falling back to abortable Node I/O), while a separate watch manager owns Chokidar handles, missing-root probes, and invalidation.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry, provider, root resolution, frontmatter parsing, watch manager |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion |
+
+### Discovery flow
+
+Discovery resolves the root list for the lookup cwd, asks the watch manager to attach to each root, then scans each root's direct entries: directory bundles resolve `<name>/SKILL.md`, flat files resolve `<name>.md`. Each file is parsed for frontmatter — `name` must be kebab-case, `description` is required, and the invocation keys resolve through the strict boolean grammar — and candidates carry the root's source label and rank so the registry can merge them with other providers. Confirmed missing paths are valid empty state; malformed or non-text entries warn and skip.
+
+### Watching and invalidation
+
+Existing roots are watched by Chokidar at depth 1; a root that does not exist is followed from its nearest existing ancestor one missing segment at a time using `fs.watchFile`. Relevant events — direct bundle add/remove, flat `.md` add/remove, and direct `SKILL.md` add/remove/change — coalesce into one provider invalidation per microtask batch, while resource-subtree changes are ignored. The watch manager is bounded by `watchMaxProjects`, logs and retries failed startup, and closes every handle at teardown. First-party `write`/`edit` mutations invalidate synchronously through the `fs/observed` event.

+
+
+These limits define when the provider is a poor fit or needs special operational care. They are current package constraints, not a task backlog.
+
 - **Discovery is one level deep** — only `<root>/<name>/SKILL.md` and `<root>/<name>.md` are recognized; nested skill trees and package manifests are ignored.
 - **Project scope is the nearest `.git` ancestor** — workspaces without that marker fall back to the supplied cwd, with no alternate project-root marker or monorepo subproject selection.
 - **Malformed entries disappear with a warning** — the model catalog receives no per-skill diagnostic and cannot distinguish an absent skill from an invalid one; unexpected I/O failures preserve the last-good catalog instead.
 - **Missing-root observation polls one path segment** — roots absent at startup use `fs.watchFile` at `watchPollIntervalMs` until Chokidar can attach, trading bounded detection latency for reliable creation detection across IDE, Git, and shell workflows.
 - **No body revision protocol** — a loaded body is ordinary retained tool history; later file edits affect later calls but neither rewrite old results nor announce that the body changed.

+挂载插件即可让本地 skill 对 agent 可用。它扫描下方的项目、自定义与用户 skill 根目录，把每个 skill 的 frontmatter 解析为目录条目，并按需加载正文；它还会监视这些根目录，使新增、改名或删除的 skill 无需重启即可进入下一次目录。
 
-默认根按该提供方的 rank 顺序解析：
+### 何时选择
+
+当 skill 存放在磁盘上——仓库、自定义目录或用户的 agent 配置中——时，使用此提供方。当 skill 来自远程注册表或嵌入式插件数据时，请避免使用：注册表接受任意提供方，本包只是其中一种实现。
+
+### skill 格式
+
+skill 可以是被扫描根目录顶层的目录 bundle `<name>/SKILL.md`，也可以是平铺文件 `<name>.md`；刻意不支持发现嵌套的 `**/SKILL.md`。文件以 YAML frontmatter 开头：必填 `name` 与 `description`，另有可选 `whenToUse`、`metadata`、`disable-model-invocation` 与 `user-invocable`。
+
+`disable-model-invocation: true` 会把 skill 从面向模型的目录和 loader 中排除；`user-invocable: false` 会把它从面向用户的命令中排除，省略的字段默认允许对应接口调用。这两个键接受 YAML 布尔值，以及不区分大小写的 `true`/`false`、`yes`/`no`、`on`/`off` 和 `1`/`0` 形式；被拒绝的拼写或非布尔值会让整个 skill 随警告一起被丢弃，而不会静默允许某个接口。
+
+目录与正文具有独立的生命周期：发现阶段把 frontmatter 解析进目录条目，每次加载都会重新读取当前文件，因此编辑 skill 正文无需版本化或缓存失效。

-## 目录变更检测
+与 skill 注册表一起加载该插件；它需要 `ctx.skills`。
 
-现有 skill 根由 Chokidar 监视。打开原生 watcher 前，提供方会对现有根或祖先执行 realpath 解析，并拼回下一个缺失路径段；当 `watchFollowSymlinks` 为 false 且根本身是符号链接时，提供方不会展开最后这一级链接，使 Chokidar 能够强制执行配置边界。发现与诊断仍保留配置路径，从而避免 Windows 在 libuv 内部混用 8.3 别名与长格式事件路径。提供方会观察直属 bundle 目录的添加／移除、平铺 Markdown 文件的添加／移除，以及直接 `SKILL.md` 的添加／移除／变更；`change` 事件用于重新发现 `name`、`description` 等目录 frontmatter。`references`、`scripts`、`assets` 或其他 bundle 资源下的变更不会使目录失效。同一微任务批次内送达的事件会合并为一次提供方失效。

-不存在的根会从最近的现有祖先开始，每次沿一个缺失路径段跟踪。系统使用 `fs.watchFile` 探测下一段；当 `.agents`、`skills` 或已配置的根出现后，观察会逐级推进，直至 Chokidar 可以附加到真实根。根删除时，该过程反向执行，因此删除再重建整个 skills 目录仍可被观察到。按项目划分的 watcher 数量受 `watchMaxProjects` 限制；再次访问已被驱逐的项目时，发现阶段会重新附加观察。

-如果第一方文件系统 `write` 和 `edit` 工具的目标可能影响受监视的 skill 条目，它们还会通过 `fs/observed` 同步使提供方失效。这条快速路径让模型的下一个步骤无需等待宿主 watcher，即可观察到自身的文件系统变更。外部 IDE、Git、shell 和进程产生的变更依赖 Chokidar 或缺失路径探测。现有根的 watcher 会保持持久状态直至 effect 释放，使 Chokidar 能够接管异步原生错误事件；watcher 启动或运行时失败会被记录并触发重试。发现过程仍会扫描可读根目录，并返回其候选项供直接加载，但会将观测标记为不完整，因此不会缓存，也不会作为权威模型目录发布。effect 释放会关闭所有 watcher，并收束延迟回调。

+现有根目录会被监视，因此新增、改名或删除 skill（或编辑其 frontmatter）会在下一个模型步骤触发目录刷新；`references`、`scripts`、`assets` 等 bundle 资源下的编辑不会触发。当第一方 `write` 与 `edit` 工具的目标可能影响受监视的 skill 时，它们会直接使提供方失效，因此模型无需等待宿主 watcher 即可观察到自身的文件系统变更。外部 IDE、Git 与 shell 变更由宿主 watcher 捕获；尚不存在的根目录会被探测，直至其出现。
 
-这两个调用字段接受 YAML 布尔值，以及不区分大小写的 `true`/`false`、`yes`/`no`、`on`/`off` 和 `1`/`0`。`disable-model-invocation: true` 会从面向模型的目录和 loader 中排除该 skill；`user-invocable: false` 会从面向用户的命令中排除该 skill。每个省略的字段都默认为允许对应接口调用；提供方始终输出两个正向内部策略值，即使两个键都不存在也不例外。若使用驼峰拼写或提供非布尔调用值，系统会记录警告并从发现结果中排除整个 skill，而不是只丢弃该字段或回退到宽松的默认值。调用策略校验遵循失败时默认拒绝原则，因为忽略无效数据可能会在已禁用的接口上暴露 skill；类型错误的可选 `whenToUse` 和 `metadata` 值则会被省略，因为这两个字段目前都不授予调用权限。
+### 可观察的成功与失败
 
-目录与正文具有独立的生命周期。发现阶段解析 frontmatter 以生成概述。每次 `skill(name)` 加载都会重新读取并解析当前文件，因此正文编辑不需要 hash、修订号、缓存失效或主动通知模型。若在发现与加载之间更改 frontmatter 中的名称，系统会拒绝陈旧名称并使提供方失效；下一次目录观察会发布新名称。
+任一被扫描根目录下的有效 skill 都会按名称排序出现在会话目录中，加载它即可返回当前文件正文。缺少有效 frontmatter、名称无效或调用值无效的文件会随警告被跳过，因此模型目录不会收到逐 skill 诊断，也无法区分缺失的 skill 与无效的 skill。意外的发现或读取失败会让目录观测保持不完整，而不会用看似发生删除的结果替换最后一份可用视图。

+
+本节解释发现与监视如何组织；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+该提供方建立在两个分离之上。第一，目录与正文分离：发现阶段把 frontmatter 解析为摘要，而每次加载都重新读取文件，因此正文编辑无需 hash、修订号或缓存失效。第二，发现与监视分离：`list()` 在存在文件系统服务时通过 `ctx.fs` 扫描根目录并解析项目根（否则回退到可中止的 Node I/O），而独立的监视管理器负责 Chokidar 句柄、缺失根探测与失效。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口、提供方、根解析、frontmatter 解析、监视管理器 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件 |
+
+### 发现流程
+
+发现过程先为查找 cwd 解析根列表，让监视管理器附加到每个根，再扫描每个根的直接条目：目录 bundle 解析为 `<name>/SKILL.md`，平铺文件解析为 `<name>.md`。每个文件都会解析 frontmatter——`name` 必须为 kebab-case，`description` 必填，调用键按严格布尔语法解析——候选项携带根目录的来源标签与 rank，供注册表与其他提供方合并。已确认缺失的路径属于有效空状态；格式错误或非文本条目会随警告跳过。
+
+### 监视与失效
+
+现有根目录由 Chokidar 以深度 1 监视；不存在的根会从最近的现有祖先开始，借助 `fs.watchFile` 每次沿一个缺失路径段跟踪。相关事件——直属 bundle 添加/移除、平铺 `.md` 添加/移除、直接 `SKILL.md` 添加/移除/变更——会在每个微任务批次合并为一次提供方失效，资源子树下的变更则被忽略。监视管理器受 `watchMaxProjects` 限制，会记录并重试失败的启动，并在释放时关闭所有句柄。第一方 `write`/`edit` 变更通过 `fs/observed` 事件同步失效。

-Pure agent skill provider registry.
+## Summary
 
-This package owns the `ctx.skills` interface. It does not know whether skills come from local files, embedded plugin data, HTTP, or another backend; providers register those sources with `ctx.skills.registerProvider(...)`. The shipped local implementation is [`@deepseek-ai/dsh-skill-filesystem`](../skill-filesystem).
+Agents and users can access reusable, task-specific instructions through one lookup no matter where the instructions come from: any provider can contribute skills from local directories, embedded plugin data, or a remote service, and every consumer receives one merged catalog with the winning skill for each name and can load any skill's full instructions on demand. Mount this plugin when skills should be loadable from more than one source or from a non-filesystem source, and skip it when a composition loads no skills. It ships no skill content of its own — pair it with at least one provider (the shipped `dsh-skill-filesystem`), and with `dsh-tool-skill` when agents should load skills.
 
-The registry is host+per-scope layered over [`@deepseek-ai/dsh-scope`](../../core/scope), the shape the tools registry established: a registration files into the layer of its calling context's scope — host rows and repository plugins land in the global layer, a plugin mounted by an agent preset's standing composition lands in that preset's layer — and a read merges the global layer with the viewing scope's chain, the nearest layer winning a duplicate name outright while rank decides duplicates only within one layer.

-### Public API
+-----
 
-- `ctx.skills.registerProvider(create): () => void` Calls a synchronous provider factory with `{ signal, invalidate }`, then registers its readonly result by `provider.name`, unique within the calling context's layer. Duplicate names in one layer throw, `runtime` is reserved, and failed registration aborts the signal. The exact Cordis disposer unregisters the provider, aborts the signal, and preserves ordered composite teardown.
-- `ctx.skills.snapshot({ cwd?, signal?, scope? })` Returns the invocation-neutral `{ skills, complete }` observation for the viewing scope's merged layers. `complete` is false when any provider rejects or explicitly reports incomplete discovery, or when a second catalog revision races the bounded retry; candidates supplied by that observation remain in this result, which is never cached.
-- `ctx.skills.list({ cwd?, signal?, scope? })` Borrows the readonly view options, then returns every winning summary for the current workspace, merged across the global layer and the viewing scope's chain and sorted by name. Consumers apply `isModelInvocable(skill)` or `isUserInvocable(skill)` at their own boundary.
-- `ctx.skills.get(name, { cwd?, signal?, scope? })` Uses the same readonly options and winning candidate for discovery and loading, rechecks cancellation after discovery or a cache hit, races provider loading against the signal, validates the loaded definition, then returns it regardless of invocation policy.
-- `ctx.skills.register(skill): () => void` Registers a readonly runtime embedded skill into the calling context's layer, adding the all-invocable policy and `provider: "runtime"` when omitted. Same-name runtime registrations in one layer are first-wins: a duplicate logs a warning and gets a no-op disposer. Successful registrations return the exact Cordis disposer for ordered composite teardown.
+<a id="use-this-package"></a>
+## Use this package
 
-### Events
+Mount the plugin to give a composition one skill registry. Skill sources (providers) and consumers (the model-facing catalog and loader, or your own code) all talk to `ctx.skills`; the registry merges everything any provider reports, so one lookup sees skills from every source.
 
-- `skills/change` is an unfiltered invalidation notification emitted after a provider or runtime contribution is registered or disposed and after an active provider's registration control invalidates. It carries no catalog or diff: each consumer refetches `snapshot()` with its own lookup options. Listener throws and rejected promises are logged and cannot veto the registry mutation or starve later listeners.
+### When to choose it
 
-### Config
+Use `dsh-skill` when agents should load skills from more than one source through one interface, or when the source of skills is not the local filesystem. Avoid it when a composition needs no skill loading at all — the plugin adds a service and a per-lookup discovery cost. The shipped local provider (`dsh-skill-filesystem`) and the model-facing consumer (`dsh-tool-skill`) are separate packages; mount them alongside when the deployment wants local skills and model access.
+
+### Mount and configure
+
+Load the plugin like any Cordis plugin. The only configuration limits how many completed provider catalogs are kept in memory; everything else is provider behavior.
+
+```yaml
+- name: '@deepseek-ai/dsh-skill'
+```
 
 | Field | Default | Meaning |
 |---|---|---|
-| `collectCacheMaxEntries` | `128` | Maximum completed cwd/provider catalogs kept in memory. |
+| `collectCacheMaxEntries` | `128` | Completed cwd/provider catalogs kept in memory |
 
-### Invocation policy
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-skill) is the exhaustive source for every accepted field.
 
-`SkillSummary.invocation` is a required typed policy object whose positive booleans `modelInvocable` and `userInvocable` describe the two surfaces independently. Providers return this resolved shape on every candidate and definition; only the `SkillRegistration` input may omit it, in which case `register()` supplies `{ modelInvocable: true, userInvocable: true }`. The registry keeps all four combinations so one discovery result can serve model-facing tools, human-facing commands, and trusted internal callers without conflating their catalogs.
+### What the registry gives you
+
+- **One merged catalog.** A consumer asks for the current catalog of a workspace and receives every winning skill summary from every provider, sorted by name — no provider-specific ordering or deduplication to do.
+- **On-demand loading.** Asking for one skill by name returns the full instruction body from whichever provider owns the winning candidate; the registry re-validates the loaded definition and rejects a stale selection whose name changed between discovery and load.
+- **Embedded skills.** Plugins register an in-memory skill with `ctx.skills.register(...)`; the registry fills in a default invocation policy and the `runtime` provider label. Same-name runtime registrations in one layer are first-wins with a warning.
+- **Provider registration.** A provider contributes its catalog with `ctx.skills.registerProvider(...)`; registration is synchronous, and the returned disposer removes the provider. `runtime` is a reserved provider name.
+
+An invocation policy on every skill decides which surfaces may advertise and load it: `modelInvocable` for model-facing tools and catalogs, `userInvocable` for human-facing commands. The registry keeps all four combinations, so one discovery result can serve both surfaces without conflating their catalogs.

-### Shared model-facing rendering
+### Observable success and failures
 
-`renderSkillContent(skill)` renders one loaded skill as the canonical `<skill_content>` block (escaped `name` attribute, resource hints, verbatim body). It is the single truth for both loading paths: `dsh-tool-skill` returns it as the `skill` tool result and injects it at the user-explicit gesture boundary, so the model sees one shape regardless of who initiated the load. `escapeText` is exported beside it for consumers embedding prose in the same markup frame. The package also declares the `skill-invocation` `MessageSource` kind ({ name, form: 'instructions' }) that user-explicit injection stamps on its messages — transcript consumers present the invocation from this metadata instead of re-parsing the body.
+A skill that any provider reports appears in the merged catalog, and loading it by its exact kebab-case name returns the body; an invalid name returns no skill rather than throwing. A provider that fails discovery is logged and skipped, and the observation is reported incomplete so consumers keep their last-good catalog; an explicit incomplete observation still contributes its candidates. A malformed candidate fails fast — the registry validates names, descriptions, invocation booleans, and provider ownership before caching or returning anything.
 
-`isModelInvocable(skill)` and `isUserInvocable(skill)` read the matching positive field directly. `ctx.skills.get()` remains the trusted, policy-neutral loading primitive, so every user- or model-facing consumer must enforce the predicate that matches its surface before exposing or loading a skill.
+-----
 
-## Provider Contract
+<a id="understand-the-implementation"></a>
+## Understand the implementation
 
-A provider factory runs synchronously and receives one registration-scoped control. `control.signal` aborts when registration fails or is disposed; `control.invalidate()` clears completed catalogs only while that exact registration remains active, so late callbacks cannot affect a replacement with the same name. Immutable providers may ignore the control. Remote setup, authentication, and discovery belong in the provider's awaited `list(options)` call. An array return is shorthand for complete discovery; a provider that collected usable candidates but could not establish an authoritative observation returns `{ candidates, complete: false }`. Provider objects, lookup options, candidates, and definitions are borrowed readonly rather than cloned or rebound. Providers should honor `options.signal`; the registry also stops awaiting uncooperative discovery or loading after cancellation.
+<details>
+<summary>Implementation internals — click to expand</summary>
 
-The registry validates candidates before caching and definitions before returning them. The winning provider receives the same candidate and opaque `locator` it returned from `list()`, allowing backend-specific file, URL, id, or version handles. Callers and providers must preserve the readonly contract.
+This section explains how the registry merges, caches, and invalidates provider catalogs; the observable behavior is fully covered in [Use this package](#use-this-package).
 
-Contract violations fail fast. A rejected provider `list()` is treated as a transient source failure and omitted. An explicit incomplete observation still contributes its candidates for `list()` and `get()`, but makes the aggregate snapshot incomplete and uncacheable. A provider or runtime revision change discards an in-flight result and retries once. If the retry is also superseded, its candidates are returned incomplete and uncached so a continuously invalidating provider cannot monopolize the caller. Within one layer, duplicate names resolve by rank, provider registration order, then provider-local order; across layers the nearest scope's entry wins the name. Summaries are sorted by skill name.
+### Design concept
 
-Definitions remain progressively loaded. `get()` asks the winning provider for the body on every call rather than caching it in this registry. If the returned definition has a different name from the selected candidate, the stale selection is rejected and the registry internally invalidates that exact provider so the next snapshot rediscovers its catalog.
+The package is built on one separation: the registry owns merging, winning resolution, and validation, while providers own where skills come from. A provider is a borrowed same-process object with a `list()` that returns candidates and a `get()` that loads a body; the registry never inspects skill content beyond validating its semantic fields.
 
-## Runtime Skills
+The registry is host+per-scope layered, the shape the tools registry established: a registration files into the layer of its calling context's scope — host rows and repository plugins land in the global layer, a plugin mounted by an agent preset's standing composition lands in that preset's layer. A read merges the global layer with the viewing scope's chain; the nearest layer wins a duplicate name outright, and within one layer duplicates resolve by rank, provider registration order, then provider-local order.
 
-`ctx.skills.register(...)` is a convenience for embedded runtime skills. Runtime skills use rank `250`: project providers can override them, while they override the shipped local provider's custom and user roots. Runtime definitions and nested resource metadata are borrowed readonly; the service materializes one top-level definition to supply omitted invocation and provider defaults. Registration is first-wins within runtime contributions, so a duplicate contribution cannot remove the active one through its disposer.
+### Source map
 
-## Consumer boundary
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry, `SkillRegistry` service, candidate and definition validation, shared model-facing rendering |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion |
 
-The registry does not render model guidance or register model-facing tools. [`@deepseek-ai/dsh-tool-skill`](../tool-skill) consumes `ctx.skills` to provide durable session catalogs and the `skill` tool, so providers remain independent of model-facing behavior.
+### Catalog collection
 
+A read (`list`/`snapshot`) collects each layer's candidates: runtime skills first, then each provider's `list()` result, awaiting providers sequentially and containing failures. Candidates are validated, deduplicated within the layer, and merged across layers; summaries sort by name. Completed collections are cached per cwd, scope chain, and revision up to `collectCacheMaxEntries`; an in-flight collection retries once when a provider or runtime mutation bumps the revision mid-read, and a second change returns the latest candidates as an incomplete, uncached observation.
+
+### Loading and staleness
+
+`get()` selects the winning candidate, races the provider's load against the lookup's abort signal, and rechecks cancellation after selection or a cache hit. The returned definition must match the selected candidate's name; a mismatch invalidates the cached catalogs so the next snapshot rediscovers the provider's skills. Definitions are never cached — every load asks the provider for the current body.
+
+### Invalidation
+
+The registry has no TTL: only a provider calling its registration-scoped `invalidate()`, or a runtime registration or disposal, clears completed catalogs. Each invalidation bumps a revision, clears the cache, and emits the unfiltered `skills/change` event; consumers refetch with their own lookup options. `invalidate()` takes effect only while the exact registration that received it is still active, so a late callback cannot disturb a replacement provider with the same name.

-纯 agent skill（智能体技能）提供方注册表。
+## 概述
 
-该包负责 `ctx.skills` 接口。它不知道 skill 来自本地文件、嵌入式插件数据、HTTP 还是其他后端；提供方通过 `ctx.skills.registerProvider(...)` 注册这些来源。已发布的本地实现是 [`@deepseek-ai/dsh-skill-filesystem`](../skill-filesystem)。
+agent（智能体）和用户可以通过单一查找使用可复用的任务专项指令，无论指令来自何处：任意提供方都可以从本地目录、嵌入式插件数据或远程服务贡献 skill（技能），每个消费方都会收到一份合并目录——每个名称对应胜出的 skill——并能按需加载任一 skill 的完整指令。当组合需要从多个来源或非文件系统来源加载 skill 时，请挂载本插件；当组合完全不加载 skill 时，请跳过。它自身不携带任何 skill 内容——请至少搭配一个提供方（随附的 `dsh-skill-filesystem`）；需要 agent 加载 skill 时，再搭配 `dsh-tool-skill`。
 
-注册表基于 [`@deepseek-ai/dsh-scope`](../../core/scope) 采用宿主 + 按 scope 的分层结构，即工具注册表确立的形态：注册落入调用方上下文 scope 对应的层——宿主行与 repository 插件落入全局层，由 agent preset 常驻组合挂载的插件落入该 preset 的层——读取时将全局层与观察 scope 的链合并，最近层直接赢得重名，rank 只在单层内裁决重名。

+## 使用本包
 
-### 事件
+挂载插件即可让组合拥有一个统一的 skill 注册表。skill 来源（提供方）和消费方（面向模型的目录与 loader，或你自己的代码）都通过 `ctx.skills` 交互；注册表合并任意提供方报告的一切内容，因此一次查找就能看到所有来源的 skill。
 
-- `skills/change` 是一条不带过滤条件的失效通知，在提供方或运行时贡献注册或释放后，以及活动提供方的注册控制触发失效后发出。它不携带目录或 diff；每个消费方都使用自身的查找选项重新获取 `snapshot()`。监听器抛错或 Promise 拒绝会被记录，既不能否决注册表变更，也不能阻止后续监听器执行。
+### 何时选择
 
-### 配置
+当 agent 需要通过同一个接口从多个来源加载 skill，或 skill 来源并非本地文件系统时，选择 `dsh-skill`。当组合完全不需要加载 skill 时，请避免使用——插件会增加一个服务以及每次查找的发现成本。随附的本地提供方（`dsh-skill-filesystem`）和面向模型的消费方（`dsh-tool-skill`）是独立包；部署需要本地 skill 和模型访问时，请一并挂载。
+
+### 挂载与配置

+### 注册表提供什么
+
+- **合并后的单一目录。** 消费方查询工作区的当前目录，即可收到来自所有提供方的全部胜出 skill 摘要，并按名称排序——无需自行做提供方特有的排序或去重。
+- **按需加载。** 按名称查询某个 skill，会从拥有胜出候选项的提供方返回完整指令正文；注册表会重新验证加载的定义，并拒绝在发现与加载之间名称发生变化的陈旧选择。
+- **嵌入式 skill。** 插件可用 `ctx.skills.register(...)` 注册内存中的 skill；注册表会补入默认调用策略与 `runtime` 提供方标签。同层同名运行时注册采用先到先得，并记录警告。
+- **提供方注册。** 提供方用 `ctx.skills.registerProvider(...)` 贡献目录；注册是同步的，返回的 disposer（资源释放）会移除该提供方。`runtime` 是保留的提供方名称。

-### 共享的面向模型渲染
+### 可观察的成功与失败
 
-`renderSkillContent(skill)` 把一个已加载 skill 渲染为规范的 `<skill_content>` 块（转义后的 `name` 属性、资源提示、原样正文）。它是两条加载路径的唯一真源：`dsh-tool-skill` 将其作为 `skill` 工具结果返回，并在用户显式的手势边界将其注入，因此无论加载由谁发起，模型看到的都是同一种形态。`escapeText` 随之一并导出，供要在同一标记框架中嵌入文案的消费方使用。该包还声明 `skill-invocation` 这个 `MessageSource` kind（{ name, form: 'instructions' }），用户显式注入会把它打在自己的消息上——transcript（文本记录）消费方依据这份元数据呈现该次调用，而不是重新解析正文。
+任意提供方报告的 skill 都会出现在合并目录中，按其精确 kebab-case 名称加载即可返回正文；无效名称返回无结果而非抛错。发现失败的提供方会被记录并跳过，观测被标记为不完整，因此消费方保留其最后一份可用目录；显式的不完整观测仍会贡献其候选项。格式错误的候选项会快速失败——注册表在缓存或返回任何内容之前，会先验证名称、描述、调用布尔值与提供方归属。
 
-`isModelInvocable(skill)` 和 `isUserInvocable(skill)` 分别直接读取对应的正向字段。`ctx.skills.get()` 仍是受信且与策略无关的加载原语，因此每个面向用户或模型的消费方都必须先执行与自身接口匹配的判定，再暴露或加载 skill。
+-----
 
-## 提供方约定
+<a id="understand-the-implementation"></a>
+## 理解实现
 
-提供方工厂同步运行，并接收一项注册作用域内的控制能力。注册失败或释放时，`control.signal` 会中止；仅当该精确注册仍处于活动状态时，`control.invalidate()` 才会清除已完成目录，因此延迟回调无法影响同名替代项。不可变提供方可以忽略该控制能力。远程设置、身份验证和发现应在提供方的 `list(options)` 调用中完成，该调用会被等待。返回数组是完整发现的简写形式；若提供方已收集到可用候选项，却无法建立权威观测，则返回 `{ candidates, complete: false }`。提供方对象、查找选项、候选项和定义都以只读方式借用，而不是克隆或重新绑定。提供方应遵守 `options.signal`；取消后，注册表也会停止等待不协作的发现或加载。
+<details>
+<summary>实现细节——点击展开</summary>
 
-注册表在缓存前验证候选项，在返回前验证定义。胜出提供方会收到同一候选项和不透明 `locator`，两者都是它从 `list()` 返回的内容，从而支持后端专用文件、URL、id 或版本句柄。调用方和提供方必须保持只读约定。
+本节解释注册表如何合并、缓存并失效提供方目录；可观察行为已在[使用本包](#use-this-package)中完整说明。
 
-违反约定时会快速失败。`list()` 返回的 Promise 被拒绝会被视为瞬时来源失败，并省略其结果。显式的不完整观测仍会为 `list()` 和 `get()` 提供其候选项，但会使聚合快照不完整且不可缓存。提供方或运行时修订发生变化时，会丢弃正在进行的结果并重试一次。如果这次重试也被后续修订取代，则返回其候选项，并将结果标为不完整且不予缓存，以免持续触发失效的提供方一直占用调用方。单层内重复名称依次按 rank、提供方注册顺序和提供方本地顺序解决冲突；跨层则由最近 scope 的条目赢得名称。摘要按 skill 名称排序。
+### 设计理念
 
-定义仍采用渐进式加载。`get()` 每次调用都会向胜出提供方请求正文，而不是在此注册表中缓存正文。若返回定义的名称不同于所选候选项，系统会拒绝该陈旧选择，并由注册表在内部使该精确提供方失效，以便下一次快照重新发现其目录。
+本包建立在一个分离之上：注册表负责合并、胜出解析与验证，提供方负责 skill 来自哪里。提供方是借用的同进程对象，其 `list()` 返回候选项、`get()` 加载正文；注册表除验证语义字段外，从不检查 skill 内容。
 
-## 运行时 skill
+注册表采用宿主 + 按 scope 的分层结构，即工具注册表确立的形态：注册落入调用方上下文 scope 对应的层——宿主行与 repository 插件落入全局层，由 agent preset 常驻组合挂载的插件落入该 preset 的层。读取时将全局层与观察 scope 的链合并；最近层直接赢得重名，单层内重名则依次按 rank、提供方注册顺序与提供方本地顺序裁决。
 
-`ctx.skills.register(...)` 是嵌入式运行时 skill 的便利接口。运行时 skill 使用 rank `250`：项目提供方可覆盖它们，它们则覆盖已发布本地提供方的自定义根目录和用户根目录。运行时定义和嵌套资源元数据均以只读方式借用；服务只物化一个顶层定义，以补入省略的调用策略和 `provider` 默认值。运行时贡献内的注册使用先到先得，因此重复贡献无法通过其 disposer 移除当前生效的贡献。
+### 源码地图
 
-## 消费方边界
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口、`SkillRegistry` 服务、候选项与定义验证、共享的面向模型渲染 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件 |
 
-注册表不渲染模型指引，也不注册面向模型的工具。[`@deepseek-ai/dsh-tool-skill`](../tool-skill) 消费 `ctx.skills` 以提供持久会话目录和 `skill` 工具，因此提供方仍与模型接口独立。
+### 目录收集
 
+读取（`list`/`snapshot`）会收集每一层的候选项：先是运行时 skill，再是各提供方的 `list()` 结果，提供方依次等待、失败被包含。候选项经验证后在层内去重，跨层合并；摘要按名称排序。完成的收集按 cwd、scope 链与 revision 缓存，上限为 `collectCacheMaxEntries`；读取中途提供方或运行时变更使 revision 递增时，进行中的收集会重试一次，第二次变更则返回最新候选项并标记为不完整、不予缓存。
+
+### 加载与陈旧
+
+`get()` 选择胜出候选项，让提供方加载与查找的中止信号竞速，并在选择或缓存命中后重新检查取消。返回的定义必须与所选候选项同名；名称不符会使缓存目录失效，以便下一次快照重新发现该提供方的 skill。定义从不缓存——每次加载都向提供方请求当前正文。
+
+### 失效
+
+注册表没有 TTL：只有提供方调用其注册作用域内的 `invalidate()`，或发生运行时注册或释放时，才会清除已完成的目录。每次失效都会递增 revision、清空缓存，并发出不带过滤条件的 `skills/change` 事件；消费方用各自的查找选项重新获取。`invalidate()` 仅当接收它的那条精确注册仍处于活动状态时才生效，因此延迟回调无法干扰同名替代提供方。

-The model-facing skill catalog and `skill` tool.
+## Summary
 
-Requires `ctx.agents`, `ctx.tools`, and `ctx.skills` (`inject: ['agents', 'tools', 'skills']`).
+Agents can discover and load skills during a session: before the first request they receive a durable catalog of every available skill's name and capped description, and they can load any listed skill's full instructions by name through the `skill` loader tool. A user can also invoke a skill directly with a `/name` token, which injects that skill's instructions into the step. The catalog stays current: membership, description, or visibility changes append a complete replacement catalog, and a deleted skill is explicitly retired. Mount it alongside the skill registry (and at least one provider) when agents should load skills; its only configuration caps catalog description length.
 
-## Catalog lifecycle
+## Table of Contents
 
-At every eligible `agent/pre-step`, the plugin calls `ctx.skills.snapshot()` for the calling session's cwd, forwards the pre-step abort signal to discovery, applies exact `skill` tool visibility, and renders the ordered `name` and `description` entries. When no prior catalog exists and that view is non-empty, it adds an initial durable user-role `<system-reminder>` to a downstream `enter` decision. Catalog messages contain only those summaries; skill bodies, paths, sources, providers, and `whenToUse` hints remain outside the catalog.

+- [Further Exploration](#further-exploration)

+- [Known Limitations and Deferred Work](#known-limitations-and-deferred-work)
+- [Dev Note](#dev-note)
 
-Every catalog message carries the `skill-catalog` source: a `catalog`-form context whose `entries` record exactly the `name` and `description` pairs it published, plus `update` on a replacement. The digest covers those durable entries, not the rendered prose, so the surrounding `<system-reminder>` framing cannot decide whether a republish is needed and consumers never re-parse the `<available_skills>` block. The plugin scans durable session events backwards without copying them and derives the comparison baseline from the newest visible `skill-catalog` message it can read; unreadable and foreign records are skipped. When the digest changes, the downstream `enter` decision receives a durable user-role message containing the complete replacement catalog; an empty replacement explicitly retires earlier names. If no catalog remains visible but a recognizable historical catalog exists, compaction hid it and the next complete observation re-establishes the current catalog. An incomplete provider snapshot emits nothing and preserves the last-good model view for retry at the next pre-step. If no prior catalog exists and the current view is empty, no tombstone is necessary.
+-----
 
-The catalog is omitted when no model-invocable skills are initially available, and also when that agent's tool view restricts away the shipped `skill` tool or resolves a same-name scoped shadow instead. Identity is compared against the definition this plugin registered rather than a lookup of its own name, so the plugin works mounted globally or inside one agent's composition, where `register()` files into that agent's layer alone. Visibility changes participate in the digest, keeping prompt guidance, model-visible schema, and executable dispatch aligned.

-`catalogDescriptionMaxLength` controls normalized catalog descriptions; rendering XML-escapes them. Its default is `500` and values must be integers of at least `3`, which reserves room for a truncation ellipsis. The [skill catalog hot-refresh Agent Note](../../../.agents/notes/implemented/feature/2026-07-27-skill-catalog-hot-refresh.md) owns the durable initial catalog and replacement lifecycle.
+Mount the plugin alongside the skill registry to give agents a session skill catalog and the `skill` loader tool. It requires `ctx.agents`, `ctx.tools`, and `ctx.skills`.
 
-## Tool: `skill`
+### When to choose it
 
-| Arg | Type | Notes |
+Use it when agents should discover and load skills during a session. Skip it when skill loading is handled by another consumer or not needed at all — without it, providers and the registry still work, but nothing renders a catalog or a tool for the model.
+
+### Mount and configure
+
+Load the plugin together with the skill registry and at least one provider. The only configuration caps the normalized description length rendered in the catalog.
+
+```yaml
+- name: '@deepseek-ai/dsh-skill'
+- name: '@deepseek-ai/dsh-skill-filesystem'
+- name: '@deepseek-ai/dsh-tool-skill'
+```
+
+| Field | Default | Meaning |
 |---|---|---|
-| `name` | string (required) | Exact kebab-case skill name from the available skills listing. |
+| `catalogDescriptionMaxLength` | `500` | Maximum normalized description length rendered in the session catalog; minimum 3 |
 
-Execution uses the calling agent's `session.header.cwd` so workspace-sensitive providers resolve the winning skill. A successful call returns canonical `{ name, provider, resourceBase?, content }`, excluding catalog ranking and provider-internal machinery; its Native renderer produces one text result containing `<skill_content name="...">`, `<skill_resources>`, and `<skill_instructions>`.
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-tool-skill) is the exhaustive source for every accepted field.
 
-Resource guidance resolves only paths or URLs explicitly referenced by the instructions against `resourceBase`; scripts, references, and assets load on demand, and the result does not enumerate a skill directory. Local providers may supply a directory, while remote or embedded providers may supply a URL or opaque loading guidance.
+### What the model gets
 
-An unresolved name reports that the skill is unknown or no longer available. Invalid names and skills whose `invocation.modelInvocable` is `false` produce distinct error results. `invocation.userInvocable` does not restrict this model-facing tool.
+- **A session catalog.** When model-invocable skills exist and the `skill` tool is visible, the agent receives a durable user-role message before its first request, listing each skill's name and a capped description; the message tells the model to load a skill with the tool before acting on it, and never to infer instructions from the summary alone.
+- **A loader tool.** The model calls `skill` with the exact skill name and receives the full instruction body plus resource guidance in a canonical `<skill_content>` block; the result is retained as ordinary tool history.
+- **Explicit user invocation.** A `/name` token in direct user input that names a user-invocable skill injects that skill's instructions into the step, without the model having to load it.
+- **Live catalog updates.** Later membership, description, or visibility changes append a complete replacement catalog; removing every skill appends an empty catalog that retires older names.
 
-Tool execution does not add a synthetic context message. Its freshly loaded result is already recorded as the tool result and becomes available to the next model step without duplicating the body. Only the catalog projection adds replacement summaries.
+### Observable success and failures
 
+Loading a listed skill returns its full instructions; the model sees one canonical shape whether the load came from the tool or from a user's explicit invocation. An invalid name reports `Error: invalid skill name "<name>"`, an unknown name reports the skill is unknown or no longer available, and a skill disabled for model invocation reports it is not available for model invocation. The catalog is omitted entirely only when no model-invocable skills exist and none was ever published; a later visibility loss — the `skill` tool hidden or shadowed by a same-name scoped tool — instead appends an empty retirement catalog, as when every skill is removed.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the catalog and the invocation boundary are built; the observable behavior is fully covered in [Use this package](#use-this-package) and the Model Experience section below.
+
+### Design concept
+
+The package is built on two ideas. First, the catalog is a durable projection, diffed by a digest over the published entries rather than the rendered prose, so the `<system-reminder>` framing can never force a republish and consumers never re-parse the `<available_skills>` block. Second, one canonical rendering serves both load paths — the tool result and the user-explicit injection — through `renderSkillContent` shared from `dsh-skill`, so the model sees the same `<skill_content>` shape regardless of who initiated the load.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: tool registration, catalog and gesture pre-step listeners, rendering and digest |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion |
+
+### Catalog lifecycle
+
+At each eligible `agent/pre-step`, the plugin snapshots the calling session's skill catalog, applies exact `skill` tool visibility, filters to model-invocable skills, and compares a digest of the entries against the newest visible `skill-catalog` message in the session log. When the digest changed, it hands the `enter` decision a durable user-role message containing the complete replacement catalog; an empty replacement explicitly retires earlier names. An incomplete provider snapshot emits nothing and preserves the last-good view for the next pre-step. The visibility check compares against the exact tool definition this plugin registered, so a scoped same-name shadow removes both the schema and its guidance; the plugin works mounted globally or inside one agent's composition.
+
+### Invocation boundary
+
+The `/name` gesture listener scans only claimed user messages: a whitespace-bounded token naming a user-invocable skill in the workspace catalog injects the same `<skill_content>` rendering as a `user`-role instructions context appended after every other injection. Unknown names and user-disabled skills stay ordinary prose. This is the only entry point for `disable-model-invocation` skills, which the catalog and the `skill` tool never expose.

 ## Model Experience
 
 ### Session catalog
 
 #### What the model sees
 
-If model-invocable skills exist and this exact `skill` tool is visible, the agent receives the catalog template below as a durable user-role message before the first request, with one data-dependent entry per sorted skill. Later membership, description, or visibility changes append a complete replacement using the same `<available_skills>` envelope; deleting every skill appends an empty envelope with an explicit instruction not to use older names. The template's closing sentence is the rule against double-loading: the user-explicit gesture boundary (the pre-step listener below) injects the same `renderSkillContent` output (shared from `@deepseek-ai/dsh-skill`) inline, and the catalog tells the model to follow that block instead of re-loading the skill through the tool; the replacement-catalog template carries the same sentence in both arms, including the emptied catalog.

 ## Known Limitations and Deferred Work
 
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define when the catalog or the loader is a poor fit. They are current package constraints, not a task backlog.
+
 - **The catalog omits `whenToUse`, source, and provider metadata** — routing is based only on name and a capped description; `whenToUse` remains provider metadata and is not rendered by the loaded wrapper either.
 - **Loaded instruction bodies have no size cap** — a provider can return a skill large enough to consume substantial next-step context; only catalog descriptions are truncated.
 - **Resources are guidance, not attachments** — the tool reports a base directory/URL/opaque hint but neither enumerates nor fetches referenced files for the model.
 - **Loading is one-shot text** — there is no partial, streaming, or cached-content handle when a remote provider is slow or a skill body is large.
-- **Catalog replacement is whole-list** — one changed name or description appends every currently visible summary; this keeps stale-name retirement explicit but costs tokens proportional to the catalog.
+- **Catalog replacement is whole-list** — one changed name or description appends every visible summary; this keeps stale-name retirement explicit but costs tokens proportional to the catalog.

-面向模型的 skill（技能）目录和 `skill` 工具。
+## 概述
 
-需要 `ctx.agents`、`ctx.tools` 和 `ctx.skills`（`inject: ['agents', 'tools', 'skills']`）。
+agent（智能体）可以在会话期间发现并加载 skill（技能）：在首次请求前，它们会收到一份持久目录，列出每个可用 skill 的名称与有长度上限的描述，并可通过 `skill` 加载工具按名称加载任一列出 skill 的完整指令。用户也可以用 `/name` token 直接调用某个 skill，把该 skill 的指令注入当轮次。目录保持最新：成员关系、描述或可见性变化会追加完整的替换目录，被删除的 skill 会被显式停用。当 agent 需要加载 skill 时，请把它与 skill 注册表（以及至少一个提供方）一起挂载；它唯一的配置项限制目录描述长度。
 
-## 目录生命周期
+## 目录
 
-每次符合条件的 `agent/pre-step`，该插件都会使用调用会话的 cwd 调用 `ctx.skills.snapshot()`，将 pre-step 中止信号转发到发现流程，应用 `skill` 工具的精确可见性，并按顺序渲染 `name` 和 `description` 条目。如果先前不存在目录且该视图非空，插件会向下游 `enter` 决策添加初始的持久用户角色 `<system-reminder>`。目录消息只包含这些摘要；skill 正文、路径、来源、提供方和 `whenToUse` 提示仍位于目录之外。

-每条目录消息都携带 `skill-catalog` 来源，也就是 `catalog` 形态的上下文。它的 `entries` 精确记录本次发布的 `name` 与 `description` 对，替换目录另带 `update`。digest 覆盖这些持久条目，而不是渲染后的正文，因此 `<system-reminder>` 包装不会影响是否需要重新发布，消费方也不需要重新解析 `<available_skills>` 块。插件从后向前扫描持久会话事件且不复制，并以最新一条仍可见且可读的 `skill-catalog` 消息作为比较基线；不可读和外来的记录都会跳过。digest 变化时，下游 `enter` 决策会收到一条包含完整替换目录的持久用户角色消息；空替换会显式停用较早的名称。如果已无目录可见，但历史中存在可识别目录，则说明压缩（compaction）已将其遮蔽，下一次完整观察会重新建立当前目录。提供方快照不完整时，插件不会发送任何内容，并会保留最后一次完整的模型视图，在下一次 pre-step 重试。若不存在先前目录且当前视图为空，则不需要 tombstone。
+-----
 
-如果最初没有模型可调用 skill，则省略目录；如果该 agent（智能体）的工具视图排除了随附的 `skill` 工具，或解析出同名的作用域内遮蔽项，也会省略目录。身份比对针对本插件所注册的那个定义，而非按自身名字回查，因此本插件既可全局挂载，也可挂在单个 agent 的组装内——在后者中 `register()` 只注册到该 agent 的层中。可见性变更参与 digest 计算，使提示词指引、模型可见 schema 和可执行分派保持对齐。
+<a id="use-this-package"></a>
+## 使用本包
 
-`catalogDescriptionMaxLength` 控制规范化后的目录描述，渲染时会对其执行 XML 转义。其默认值是 `500`，且必须是不小于 `3` 的整数，以便为截断省略号保留空间。[skill 目录热刷新 Agent Note](../../../.agents/notes/implemented/feature/2026-07-27-skill-catalog-hot-refresh.zh.md) 负责定义持久初始目录和替换目录的生命周期。
+与 skill 注册表一起挂载该插件，即可让 agent 拥有会话 skill 目录和 `skill` 加载工具。它需要 `ctx.agents`、`ctx.tools` 与 `ctx.skills`。
 
-## 工具：`skill`
+### 何时选择
 
-| 参数 | 类型 | 说明 |
+当 agent 应在会话期间发现并加载 skill 时使用它。当 skill 加载由其他消费方处理或完全不需要时，请跳过——没有它，提供方与注册表仍可工作，但不会有任何东西为模型渲染目录或工具。
+
+### 挂载与配置
+
+与 skill 注册表和至少一个提供方一起加载该插件。唯一配置项限制目录中渲染的规范化描述长度。
+
+```yaml
+- name: '@deepseek-ai/dsh-skill'
+- name: '@deepseek-ai/dsh-skill-filesystem'
+- name: '@deepseek-ai/dsh-tool-skill'
+```
+
+| 字段 | 默认值 | 含义 |
 |---|---|---|
-| `name` | string（必填） | 可用 skill 列表中精确的 kebab-case skill 名称。 |
+| `catalogDescriptionMaxLength` | `500` | 会话目录中渲染的规范化描述最大长度；最小为 3 |
 
-执行使用调用 agent 的 `session.header.cwd`，使结果随工作区变化的提供方能够解析出胜出的 skill。成功调用返回规范形式的 `{ name, provider, resourceBase?, content }`，其中不包含目录排名和提供方内部机制；其 Native 渲染器会生成一个文本结果，其中包含 `<skill_content name="...">`、`<skill_resources>` 和 `<skill_instructions>`。
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-tool-skill)是每个受支持字段的穷尽式真源。
 
-资源指引只会根据 `resourceBase` 解析指令显式引用的路径或 URL；脚本、参考资料和资源文件按需加载，结果不会列举 skill 目录。本地提供方可以提供目录，而远程或嵌入式提供方可以提供 URL 或不透明加载指引。
+### 模型得到什么
 
-无法解析的名称会报告 skill 未知或已不可用。无效名称和 `invocation.modelInvocable` 为 `false` 的 skill 会产生不同的错误结果。`invocation.userInvocable` 不限制这个面向模型的接口。
+- **会话目录。** 当存在模型可调用 skill 且 `skill` 工具可见时，agent 会在首次请求前收到一条持久的用户角色消息，列出每个 skill 的名称与有长度上限的描述；该消息告诉模型在着手任务前先用工具加载 skill，且绝不能仅凭摘要推断指令。
+- **加载工具。** 模型以精确的 skill 名称调用 `skill`，并收到完整指令正文以及规范的 `<skill_content>` 块中的资源指引；该结果作为普通工具历史保留。
+- **用户显式调用。** 直接用户输入中的 `/name` token 若指名某个用户可调用 skill，会把该 skill 的指令注入当轮次，而无需模型自行加载。
+- **实时目录更新。** 后续成员关系、描述或可见性变化会追加完整的替换目录；删除全部 skill 时会追加空目录，停用较早的名称。
 
-工具执行不会添加合成上下文消息。新加载的结果已作为工具结果记录，并在下一个模型步骤可用，无需重复正文。只有目录投影会添加替换摘要。
+### 可观察的成功与失败
 
+加载列出的 skill 会返回其完整指令；无论加载来自工具还是用户的显式调用，模型看到的都是同一种规范形态。无效名称会报告 `Error: invalid skill name "<name>"`，未知名称会报告该 skill 未知或已不可用，被禁用模型调用的 skill 会报告其不可用于模型调用。只有不存在模型可调用 skill 且从未发布过目录时，目录才会被整体省略；此后的可见性丧失——`skill` 工具被隐藏或被同名作用域工具遮蔽——会改为追加空目录来停用旧名称，与删除全部 skill 时相同。

+
+本节解释目录与调用边界如何构建；可观察行为已在[使用本包](#use-this-package)和下方模型体验章节中完整说明。
+
+### 设计理念
+
+本包建立在两个想法之上。第一，目录是一种持久投影，按已发布条目的 digest 而非渲染后的正文做差异比较，因此 `<system-reminder>` 包装永远不会强制重新发布，消费方也不需要重新解析 `<available_skills>` 块。第二，一条规范渲染服务两条加载路径——工具结果与用户显式注入——经由共享自 `dsh-skill` 的 `renderSkillContent`，因此无论加载由谁发起，模型看到的都是同一种 `<skill_content>` 形态。

+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件 |
+
+### 目录生命周期
+
+在每次符合条件的 `agent/pre-step`，插件都会快照调用会话的 skill 目录，应用 `skill` 工具的精确可见性，过滤出模型可调用的 skill，并把条目 digest 与会话日志中最新可见的 `skill-catalog` 消息做比较。digest 变化时，它把包含完整替换目录的持久用户角色消息交给 `enter` 决策；空替换会显式停用较早的名称。提供方快照不完整时不发送任何内容，并为下一次 pre-step 保留最后一份可用视图。可见性检查针对本插件所注册的精确工具定义，因此作用域内同名的遮蔽项会同时移除 schema 及其指引；该插件既可全局挂载，也可挂在单个 agent 的组合内。
+
+### 调用边界
+
+`/name` 手势监听器只扫描已认领的用户消息：若某个以空白为界、指名工作区目录中用户可调用 skill 的 token 出现，则把同一份 `<skill_content>` 渲染作为 `user` 角色的指令上下文注入，追加在该步骤所有其他注入之后。未知名称与用户不可调用的名称保持为普通行文。这是 `disable-model-invocation` skill 唯一的入口，目录与 `skill` 工具永不暴露这类 skill。

 # spill/ — tool-output spill capability family
 
 English | [中文](README.zh.md)
 
-This family persists oversized tool output and replaces the inline result with a bounded preview and retrieval locator.
+## Summary
+
+The `spill/` group keeps oversized tool output out of the model's context without losing it: when a tool result exceeds a deployment's byte cap, the full text is saved to a spill artifact and the model sees a bounded preview plus a locator it can read or search later. The family splits into three packages — the storage service in `spill/`, the local filesystem backend in `spill-local/`, and the result policy in `spill-policy/` that decides when a final tool result is too large. Spilling is opt-in and best-effort: the policy acts only when `maxInlineBytes` is configured, and a storage failure leaves the original result visible. The group owns storage and result replacement only; preview mechanics live in `dsh-output-retention`, and provider resource caps remain separate.

 # spill/：工具输出 spill 能力家族
 
 [English](README.md) | 中文
 
-本家族持久化过大的工具输出，并以有界预览和取回定位信息替换内联结果。
+## 概述
+
+`spill/` 组在不丢失超大工具输出的前提下把它们挡在模型上下文之外：当某个工具结果超过部署配置的字节上限时，完整文本会保存到 spill 产物中，模型只看到有界预览和一个稍后可以读取或搜索的定位信息。该家族拆分为三个包——`spill/` 中的存储服务、`spill-local/` 中的本地文件系统后端，以及 `spill-policy/` 中决定最终工具结果何时过大并触发 spill 的结果策略。spill 是可选且尽力而为的：只有配置了 `maxInlineBytes` 时策略才会生效，存储失败时原始结果仍然可见。本组只负责存储与结果替换；预览机制归 `dsh-output-retention` 所有，提供方资源上限保持独立。

 # @deepseek-ai/dsh-spill-local
 
 English | [中文](README.zh.md)
 
-The **local-filesystem** implementation of the [`@deepseek-ai/dsh-spill`](../spill) storage seam. Registers as `ctx.spillStore` and persists a tool's oversized text to a private, session-scoped file; its locator is the file path and its retrieval hint tells the model to use `read` or `grep` on that path.
+## Summary
 
-## Storage layout
+`dsh-spill-local` saves a tool's oversized text to a private, session-scoped file on the host filesystem and returns that file's path as the locator, with retrieval guidance telling the model to read or grep it. Mount it whenever a composition needs spill storage on the same machine the agent runs on. Files are private to the current user, names are unpredictable, and each session's files group under a stable directory, so a shared root cannot leak output or be redirected by a planted symlink. Configuration selects the root and the startup-cleanup retention period; previews and spill decisions live in other packages.
 
-Files land at `<root>/session-<hash>/​<random>-<safeName>`:
+## Table of Contents
 
-- **`root`** — the config `root` (resolved to absolute), or a lazily-created private (0700) per-process directory under the OS temp dir when omitted. A predictable, world-readable root would let other local users read spilled tool output or plant symlinks.
-- **`session-<hash>`** — a short `sha256(sessionId)` prefix, so a session's spill files group together and a future cleanup can drop them per session.
-- **`<random>-<safeName>`** — an unpredictable hex prefix (defeats symlink planting in a shared root) plus the caller's `suggestedName` sanitized to one safe path segment (traversal-proof; mirrors the JSONL persistence backend's `encodeSegment`). The write is exclusive + owner-only (`open(path, 'wx', 0o600)`): it fails on any pre-existing path, symlink or not, so a planted target cannot redirect it.

-## Config
+-----
 
-| Key | Default | Meaning |
+<a id="use-this-package"></a>
+## Use this package
+
+Mount this backend in a composition that spills tool output to the local filesystem. It registers as the `ctx.spillStore` service that the `dsh-spill-policy` plugin and other callers use.
+
+### Minimal configuration
+
+Loading the plugin with no config is safe: files land in a lazily-created private (0700) per-process directory under the OS temp directory. Set `root` when the files must live under a known location.
+
+```yaml
+- name: '@deepseek-ai/dsh-spill-local'
+  config:
+    root: /absolute/path/to/spill
+    cleanupPeriodDays: 30
+```
+
+| Field | Default | Meaning |
 |---|---|---|
-| `root` | private 0700 temp dir | Root directory for spill files. Set to keep them under a known location. |
-| `cleanupPeriodDays` | `30` | Age in days after which a spill file is eligible for the one-shot startup cleanup sweep. `0` disables cleanup. |
+| `root` | private 0700 temp dir | Root directory for spill files; set to keep them under a known location |
+| `cleanupPeriodDays` | `30` | File age in days before the one-shot startup cleanup may delete it; `0` disables cleanup |
 
-## Startup cleanup
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-spill-local) is the exhaustive source for every accepted field.
 
-The backend never deletes a spill on the write path — a persisted, resumed, or forked session may still reference an older locator, so immediate deletion would break retrieval. Instead, one best-effort sweep runs **once after activation**: it does not delay service availability, is owned by the plugin fiber, and is awaited on disposal (no sweep I/O outlives the fiber). There is no recurring timer and no separate process, so a long-lived deployment is not swept again until its next restart.
+### What you get back
 
-The sweep scans the configured `root` **and** any earlier default `dsh-spill-*` temp roots that prior default-root runs left under the OS temp dir. It resolves each root to its filesystem identity, so a configured alias of a discovered root remains the active, non-prunable root. Within each root, the sweep deletes regular files whose `mtime` is strictly older than `now − cleanupPeriodDays` and prunes every empty session directory; only an empty discovered prior-default root is itself removed. A write recreates a session directory if cleanup races it. The sweep never follows or deletes a symlink and skips unrelated entries.
+Each `saveText` call writes the full text to a fresh file and returns three fields: `locator` (the file path), `bytes` (the exact UTF-8 byte count), and `retrievalHint` — "Use read with offset/limit, or grep this path to search within it." A consumer shows that hint to the model, which can then read or search the file with its ordinary file tools.
 
-On POSIX, cleanup admits only roots owned by the current user, not writable by group or others, and protected from replacement through their ancestor path; a writable sticky temporary directory such as `/tmp` is permitted. Session directories must satisfy the same ownership and write restrictions. Unsafe paths are skipped with a warning, which prevents an untrusted local process from redirecting path-based deletion outside the spill root. Every filesystem or warning-sink failure is contained, so cleanup cannot fail activation or a concurrent spill write. Retention is deliberate: an old model-visible locator goes stale only once it ages past the cutoff.
+### Where files land
 
-`saveText` rejects on a real storage failure (permissions, ENOSPC); the spill policy treats a rejection as best-effort and keeps the inline result. See the seam README for the vocabulary and the [tool output spill Agent Note](../../../.agents/notes/implemented/architecture/2026-07-08-tool-output-spill-files.md) for the design, and the [startup-cleanup Agent Note](../../../.agents/notes/implemented/architecture/2026-07-17-local-spill-startup-cleanup.md) for the sweep.
+Files are stored at `<root>/session-<hash>/<random>-<safeName>`, where `session-<hash>` is a short hash of the owning session id (so one session's files group together) and `<random>-<safeName>` pairs an unpredictable hex prefix with the caller's suggested name sanitized to one safe path segment. A relative `root` resolves from the process working directory.
 
+### Startup cleanup
+
+One best-effort sweep starts after activation without delaying service availability. It scans the configured root and prior default `dsh-spill-*` roots under the OS temp directory, deletes regular files whose modification time is strictly older than the configured cutoff, prunes empty session directories, and removes only empty prior-default roots. A long-lived process does not sweep again until restart. Disposal waits for the sweep, and a concurrent write recreates a session directory if cleanup removes it.
+
+The sweep resolves filesystem identities, never follows or deletes symlinks, and skips unrelated entries. On POSIX it admits only roots and session directories owned by the current user, not writable by group or others, and protected from replacement through their ancestor path; writable sticky temporary directories such as `/tmp` are permitted. Unsafe paths produce a warning and remain untouched. Filesystem and warning-sink failures are contained, so cleanup cannot fail activation or a concurrent spill write.
+
+### Failures and recovery
+
+A real storage failure — permissions, no space left, an unwritable root — rejects the `saveText` call; the caller decides how to degrade. The shipped policy treats the rejection as best-effort and keeps the original inline result.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the backend; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The backend owns storage details only, on one principle: **a spilled tool result must be private and unredirectable**. The root is private (0700), the session directory is a stable hash, the leaf name is unpredictable, and the write is exclusive and owner-only. The storage mechanics live in a Cordis-free module so they are unit-testable without a context.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `Config`, the `LocalSpillStore` service, cleanup lifecycle, locator and retrieval-hint assembly |
+| [`src/cleanup.ts`](src/cleanup.ts) | One-shot age sweep, filesystem-identity checks, symlink and ownership safeguards |
+| [`src/store.ts`](src/store.ts) | Cordis-free storage mechanics: private root, session directory, safe-name encoding, exclusive write |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; contracts are enforced at the seam) |
+
+### File naming and write
+
+`suggestedName` is untrusted input, so `encodeSegment` escapes every character outside `[A-Za-z0-9._-]` (and `~` itself) into a `~XXXX` form, making the mapping injective over all JS strings: separators, `../`, NUL, and absolute paths can never escape one segment, and the whole-segment tokens `.`/`..` are escaped too. The write is `open(path, 'wx', 0o600)` — it fails on any existing path, symlink or not, so a pre-planted target cannot redirect it. Two saves of the same suggested name get distinct random prefixes.

 [English](README.md) | 中文
 
-[`@deepseek-ai/dsh-spill`](../spill) 存储 seam 的**本地文件系统**实现。它注册为 `ctx.spillStore`，将工具产生的过大文本持久化到私有的会话级文件；定位信息是文件路径，取回指引会告诉模型对该路径使用 `read` 或 `grep`。
+## 概述
 
-## 存储布局
+`dsh-spill-local` 把工具的超大文本保存到宿主文件系统中私有的会话级文件，并以该文件路径作为定位信息返回，同时给出告诉模型读取或搜索它的取回指引。只要组合需要在与 agent 相同的机器上进行 spill 存储，就挂载它。文件对当前用户私有、名称不可预测，且每个会话的文件归入稳定的目录，因此共享根目录既不会泄露输出，也不会被预置的符号链接重定向。配置选择根目录与启动清理保留期；预览与 spill 决策由其他包负责。
 
-文件存放在 `<root>/session-<hash>/​<random>-<safeName>`：
+## 目录
 
-- **`root`**：使用配置中的 `root`（解析为绝对路径）；如果省略，则在操作系统临时目录下延迟创建每进程私有（0700）目录。可预测且任何用户均可读取的根目录会让其他本地用户读取 spill 工具输出，或在其中预置符号链接。
-- **`session-<hash>`**：截短的 `sha256(sessionId)` 前缀，用于将同一会话的 spill 文件归在一起，以便未来的清理操作可按会话删除。
-- **`<random>-<safeName>`**：不可预测的十六进制前缀（防止在共享根目录中预置符号链接），加上经过清理的调用方 `suggestedName`，使其成为单个安全路径段（防路径遍历；与 JSONL 持久化后端的 `encodeSegment` 一致）。写入操作采用排他方式，且权限仅限所有者（`open(path, 'wx', 0o600)`）：如果路径已经存在，无论是否为符号链接，操作都会失败，因此预置的目标无法重定向写入。

-## 启动清理
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-spill-local)是每个受支持字段的穷尽式真源。
 
-后端不会在写入路径上删除 spill，因为已持久化、已恢复或 fork 后的会话仍可能引用较旧的定位信息，立即删除会使其无法取回。后端会改为在激活后**仅运行一次**尽力而为的扫描：扫描不延迟服务可用性，由插件 fiber 拥有，并在 dispose 期间被等待（不会有扫描 I/O 存活至 fiber 之后）。它既不使用周期性定时器，也不运行独立进程，因此长期运行的部署要到下次重启才会再次扫描。
+### 你会得到什么
 
-扫描会检查配置的 `root` **以及**先前使用默认根目录的运行在操作系统临时目录下留下的所有 `dsh-spill-*` 临时根目录。它会把每个根目录解析为文件系统身份，因此当配置路径是某个已发现根目录的别名时，该目录仍会作为不可删除的活动根目录处理。在每个根目录中，扫描会删除 `mtime` 严格早于 `now − cleanupPeriodDays` 的常规文件并修剪所有空会话目录；只有发现的先前默认根目录会在变空后被删除。如果清理与写入发生竞争，写入操作会重新创建会话目录。扫描绝不会跟随或删除符号链接，并会跳过无关条目。
+每次 `saveText` 调用都会把完整文本写入一个新文件，并返回三个字段：`locator`（文件路径）、`bytes`（精确的 UTF-8 字节数）与 `retrievalHint`——"Use read with offset/limit, or grep this path to search within it."。消费方把该提示展示给模型，模型随后可以用其常规文件工具读取或搜索该文件。
 
-在 POSIX 上，清理只接受由当前用户拥有、组用户和其他用户不可写、且祖先路径可防止他人替换的根目录；`/tmp` 这类带 sticky 位的可写临时目录仍然允许使用。会话目录必须满足相同的所有权和写权限限制。不安全路径会被跳过并记录警告，从而防止不受信任的本地进程把基于路径的删除重定向到 spill 根目录之外。所有文件系统故障和警告接收方故障都会被兜底，因此清理无法使激活或并发 spill 写入失败。保留是刻意的：旧的模型可见定位信息只有超过截止时间后才会失效。
+### 文件存放位置
 
-`saveText` 在发生真实存储故障（权限、ENOSPC）时返回拒绝；spill 策略会按尽力而为原则处理该拒绝，并保留内联结果。词汇见 seam README，设计见[工具输出 spill Agent Note](../../../.agents/notes/implemented/architecture/2026-07-08-tool-output-spill-files.zh.md)，扫描机制见[启动清理 Agent Note](../../../.agents/notes/implemented/architecture/2026-07-17-local-spill-startup-cleanup.zh.md)。
+文件存放在 `<root>/session-<hash>/<random>-<safeName>`：`session-<hash>` 是所属会话 id 的短哈希（让同一会话的文件归在一起），`<random>-<safeName>` 把不可预测的十六进制前缀与清理为单个安全路径段的调用方建议名配对。相对 `root` 从进程工作目录解析。
 
+### 启动清理
+
+一次尽力而为的扫描会在激活后启动，不延迟服务可用性。它扫描配置的根目录和操作系统临时目录下先前的默认 `dsh-spill-*` 根目录，删除修改时间严格早于配置截止时间的常规文件，修剪空会话目录，并只删除已经变空的先前默认根目录。长期运行的进程要到重启时才会再次扫描。dispose 会等待扫描结束；如果清理移除了会话目录，并发写入会重新创建它。
+
+扫描会解析文件系统身份，绝不跟随或删除符号链接，并跳过无关条目。在 POSIX 上，它只接受当前用户拥有、组用户和其他用户不可写、且祖先路径能防止替换的根目录与会话目录；`/tmp` 等带 sticky 位的可写临时目录仍然允许使用。不安全路径会产生警告并保持不变。文件系统和警告接收方故障都会被兜底，因此清理无法使激活或并发 spill 写入失败。
+
+### 故障与恢复
+
+真实存储故障——权限不足、磁盘已满、根目录不可写——会让 `saveText` 调用以拒绝结束；由调用方决定如何降级。随附策略把拒绝当作尽力而为处理并保留原始内联结果。

+
+本节解释此后端背后的设计决策；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+后端只负责存储细节，建立在一个原则之上：**spill 工具结果必须私有且不可重定向**。根目录私有（0700）、会话目录是稳定哈希、文件名不可预测、写入采用排他且仅所有者模式。存储机制放在与 Cordis 无关的模块中，以便无需上下文即可单元测试。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：`Config`、`LocalSpillStore` 服务、清理生命周期、定位信息与取回提示的组装 |
+| [`src/cleanup.ts`](src/cleanup.ts) | 一次性按年龄扫描、文件系统身份检查、符号链接和所有权保护 |
+| [`src/store.ts`](src/store.ts) | 与 Cordis 无关的存储机制：私有根目录、会话目录、安全名称编码、排他写入 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；约定在 seam 处强制执行） |
+
+### 文件命名与写入
+
+`suggestedName` 是不可信输入，因此 `encodeSegment` 会把 `[A-Za-z0-9._-]`（以及 `~` 本身）之外的每个字符转义成 `~XXXX` 形式，使映射对所有 JS 字符串都是单射：分隔符、`../`、NUL 与绝对路径永远无法逃出单个路径段，整段 token `.`/`..` 也会被转义。写入采用 `open(path, 'wx', 0o600)`——任何已存在路径（无论是否符号链接）都会失败，因此预置目标无法重定向写入。对同一建议名的两次保存会得到不同的随机前缀。

 # @deepseek-ai/dsh-spill-policy
 
 English | [中文](README.zh.md)
 
-The **tool-result spill policy**: a `tools/post-execute` transformer that keeps oversized plain-text tool results out of the model's context. When a final result exceeds `maxInlineBytes`, it saves the FULL text through [`ctx.spillStore`](../spill) and replaces the model-facing result with a bounded head/tail preview plus the backend's locator and retrieval hint.
+## Summary
 
-This plugin registers **no service** and owns no storage or preview mechanics: preview is [`@deepseek-ai/dsh-output-retention`](../../util/output-retention) (`TextRetainer`), storage is `ctx.spillStore`. It only decides WHEN to spill and composes the notice.
+`dsh-spill-policy` keeps oversized plain-text tool results out of the model's context: when a final result exceeds `maxInlineBytes`, it saves the full text through `ctx.spillStore` and replaces the model-facing result with a bounded head/tail preview plus the backend's locator and retrieval guidance, which the model can use to read or grep the spill file. It registers no service and owns no storage or preview mechanics — storage is the mounted `SpillStore` backend and previews come from `dsh-output-retention`; it only decides when to spill and composes the notice. It is opt-in and best-effort: omitted `maxInlineBytes` disables it entirely, and a spill failure leaves the original result visible. A second arm applies the same cap to the durable log copy of `run_code` sub-call results, so replay and UIs never grow unbounded either.

+## Use this package
+
+Mount the policy alongside a spill backend to cap how much of a tool's plain-text result the model sees. The cap applies to final results after the tool has run; results the policy leaves alone still pass through unchanged.
+
+### Minimal configuration
+
+Load the policy with a `maxInlineBytes` budget, in UTF-8 bytes, and a spill backend:
+
+```yaml
+- name: '@deepseek-ai/dsh-spill-local'
+- name: '@deepseek-ai/dsh-spill-policy'
+  config:
+    maxInlineBytes: 50000
+```
+
+| Field | Default | Meaning |
 |---|---|---|
-| `maxInlineBytes` | *(omitted)* | Model-facing context cap for a plain-text result, in UTF-8 bytes (a non-negative integer; validated at load). **Omitted disables the policy entirely** (the plugin registers nothing). When set, a larger result is spilled and replaced with a preview derived from the same budget (head/tail split). |
+| `maxInlineBytes` | omitted | Model-facing context cap for a plain-text result, in UTF-8 bytes; omitted disables the policy entirely |
 
-## Behavior
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-spill-policy) is the exhaustive source for every accepted field. A negative or fractional cap fails plugin load rather than corrupting per-call behavior.
 
-1. Let the tool run (delegates via `next()`, so it bounds whatever a downstream hook accepted).
-2. Skip nested executions (`exec.parent` is present — their DURABLE copy is bounded by the dispatch-log arm below), accepted value replacements (the registry must revalidate and rerender them), `read` (avoids a `read → spill → read again` loop), and any non-`accept` decision (a `block`'s corrective feedback passes through).
-3. Flatten the accepted content only when it is **plain text** (all `text` blocks); a result with any non-text block is left untouched.
-4. If its UTF-8 size is `≤ maxInlineBytes`, leave it unchanged.
-5. Otherwise save the full text and replace the result with a preview + this notice, sized so the whole replacement (preview + blank line + notice) stays within `maxInlineBytes` — the notice's byte cost is reserved out of the budget, so the preview shrinks to fit and the model-facing result never exceeds the cap:
+### What the model sees
 
-   ```text
-   <retained head/tail preview>
+An oversized plain-text result is replaced by a preview plus a notice inside the same budget, so the whole replacement never exceeds `maxInlineBytes`:
 
-   (Omitted N bytes. Full formatted result stored at: /…/session-…/…-web_fetch.txt. Use read with offset/limit, or grep this path to search within it.)
-   ```
+```text
+<retained head/tail preview>
 
-   When the notice alone fills the budget (a tiny cap or a long locator) the preview is empty and only the notice is returned. If even that notice-only replacement would exceed `maxInlineBytes`, the policy keeps the inline result — it never emits a replacement over the cap (and a within-cap replacement is always smaller than the original, so this also means spilling never adds bytes).
+(Omitted N bytes. Full formatted result stored at: /…/session-…/…-web_fetch.txt. Use read with offset/limit, or grep this path to search within it.)
+```
 
-**Best-effort:** no session owner, no `ctx.spillStore` backend, or a `saveText` rejection ⇒ the policy logs a warning and returns the original result. A spill failure never turns a successful call into an `isError` or hides the inline result. A successful replacement changes only `content`; the canonical programmatic value is preserved.
+When the notice alone fills the budget (a tiny cap or a long locator), the preview is empty and only the notice is returned; if even that would exceed the cap, the policy keeps the original inline result — a within-cap replacement is always smaller than the original. The full text stays available in the spill file, and a successful replacement changes only the model-facing copy, never the canonical programmatic result.
 
-**The dispatch-log arm:** a second listener on `tools/code-dispatch-log` applies the same cap, replacement pipeline, and best-effort fallbacks to the DURABLE copy of each `run_code` sub-call result (artifact label `dispatch`, keyed by the sub-call id). The program's value is untouched — it already crossed the worker boundary whole — and `read` sub-calls are bounded too: a log copy is not model context, so the read-again loop cannot occur, and `read` is precisely the tool that produces huge logs ([rationale](../../../.agents/notes/implemented/feature/2026-07-26-code-dispatch-log-spill.md)).
+### Which results are affected
 
-## Scope
+The policy shapes only final, accepted, plain-text results. Results at or below the cap, results containing any non-text block, nested composite calls, `read` results, blocked decisions, and accepted value replacements all pass through unchanged. Provider-level truncation that already happened (for example `web-fetch-http.maxBodyChars`) cannot be recovered here — the spill file holds what the tool actually returned.
 
-The policy sees only the FINAL formatted model-facing result—not a tool's internal resource or canonical value. If a provider already truncated (e.g. `web-fetch-http.maxBodyChars`), the spill artifact holds the full formatted result the tool returned, not the full original source. Provider/resource caps stay mandatory and separate. `glob`/`grep` own item-level presentation spill because their complete acquired values still exist before rendering; bash streams own acquisition-time spill. The generic policy prepends its waterfall listener, then delegates, so ordinary tool-owned asynchronous projections complete before generic byte bounding regardless of plugin load order. See the [tool output spill Agent Note](../../../.agents/notes/implemented/architecture/2026-07-08-tool-output-spill-files.md).
+### Best-effort failure behavior
 
+A missing session owner, a missing `ctx.spillStore` backend, or a `saveText` rejection logs a warning and returns the original result. A spill failure never turns a successful call into an error and never hides the inline result.
+
+### The durable log copy
+
+The same cap also bounds the session-log copy of each `run_code` sub-call result: the program still receives the complete value, only the log's copy is replaced with the preview and locator. Oversized `read` sub-call results are bounded here too, since a log copy is not model context.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the policy; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The policy is deliberately narrow: it only decides **when** to spill and composes the notice. It registers no service, owns no storage, and owns no preview mechanics — `TextRetainer` from `dsh-output-retention` builds the head/tail preview. Two invariants shape the code: the model-facing replacement never exceeds `maxInlineBytes` (the notice's byte cost is reserved out of the budget first), and a spill failure never changes the tool call's outcome.
+
+### The two arms
+
+A `tools/post-execute` waterfall listener (registered with `prepend`, delegating via `next()`) bounds the model-facing result; a `tools/code-dispatch-log` listener bounds the durable log copy of each `run_code` sub-call. Both share one replacement helper so the two projections are byte-identical. The post-execute arm skips `read` to avoid a read → spill → read loop; the dispatch-log arm bounds `read` sub-calls because a log copy is not model context.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `Config` validation, the two waterfall listeners, the shared replacement helper |
+| [`src/types.ts`](src/types.ts) | `SpillPolicyExec`: the minimal structural view of a tool execution the policy reads for the owning session id |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; contracts are enforced at the seam) |
+
+### Failure modes
+
+Best-effort degradation applies to both arms: no session owner, no backend, a save rejection, or no within-cap replacement logs a warning and keeps the original content. Load-time validation rejects a negative or fractional `maxInlineBytes` so a bad config fails the deployment, not every oversized call.

+## 使用本包
+
+把策略与 spill 后端一起挂载，以限制模型看到的工具纯文本结果大小。上限作用于工具运行后的最终结果；策略放过的结果仍会原样通过。
+
+### 最小配置
+
+以 UTF-8 字节计的 `maxInlineBytes` 预算加载策略，并同时挂载 spill 后端：
+
+```yaml
+- name: '@deepseek-ai/dsh-spill-local'
+- name: '@deepseek-ai/dsh-spill-policy'
+  config:
+    maxInlineBytes: 50000
+```
+
+| 字段 | 默认值 | 含义 |
 |---|---|---|
-| `maxInlineBytes` | *（省略）* | 面向模型的纯文本结果上下文上限，以 UTF-8 字节数计（在加载时验证为非负整数）。**省略时完全禁用该策略**（插件不注册任何内容）。设置后，超过该上限的结果会被 spill，并替换为从同一预算派生的预览（首尾拆分）。 |
+| `maxInlineBytes` | 省略 | 纯文本结果面向模型的上下文上限（UTF-8 字节）；省略时完全禁用该策略 |
 
-## 行为
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-spill-policy)是每个受支持字段的穷尽式真源。负数或小数上限会让插件加载失败，而不是破坏每次调用的行为。
 
-1. 允许工具运行（通过 `next()` 委托，因此可以限制任何下游钩子接受的结果）。
-2. 跳过嵌套执行（存在 `exec.parent`——其持久化副本由下方的 dispatch-log 分支设界）、已接受的值替换（注册表必须重新验证并重新渲染它们）、`read`（避免 `read → spill → read again` 循环）以及任何非 `accept` 决策（`block` 的纠正反馈会原样通过）。
-3. 仅在已接受的内容为**纯文本**（全部都是 `text` 块）时才将其展平；包含任何非文本块的结果都保持不变。
-4. 如果 UTF-8 大小为 `≤ maxInlineBytes`，则保持不变。
-5. 否则，保存完整文本，并将结果替换为预览和以下通知。系统会调整大小，使整个替换内容（预览、空行和通知）不超过 `maxInlineBytes`：先从预算中保留通知所需字节，再缩小预览以适配剩余空间，因此面向模型的结果绝不会超过上限：
+### 模型看到什么
 
-   ```text
-   <retained head/tail preview>
+过大的纯文本结果会在同一预算内被替换为预览加通知，因此整个替换内容永远不会超过 `maxInlineBytes`：
 
-   (Omitted N bytes. Full formatted result stored at: /…/session-…/…-web_fetch.txt. Use read with offset/limit, or grep this path to search within it.)
-   ```
+```text
+<retained head/tail preview>
 
-   当通知本身已占满预算时（上限极小或定位信息很长），预览为空，只返回通知。如果仅通知的替换内容仍会超过 `maxInlineBytes`，策略将保留内联结果；它绝不会发出超过上限的替换内容（而且上限内的替换内容总比原结果更小，因此这也意味着 spill 绝不会增加字节数）。
+(Omitted N bytes. Full formatted result stored at: /…/session-…/…-web_fetch.txt. Use read with offset/limit, or grep this path to search within it.)
+```
 
-**尽力而为**：没有会话所有者、没有 `ctx.spillStore` 后端，或 `saveText` 返回拒绝 ⇒ 策略记录警告并返回原始结果。spill 失败绝不会将成功调用变为 `isError`，也不会隐藏内联结果。成功替换时只会更改 `content`；规范的程序化值保持不变。
+当通知本身已占满预算（上限极小或定位信息很长）时，预览为空，只返回通知；如果连这也会超过上限，策略会保留原始内联结果——上限内的替换内容总比原始结果小。完整文本仍保留在 spill 文件中，成功的替换只改变面向模型的副本，绝不改变规范的程序化结果。
 
-**dispatch-log 分支：**注册在 `tools/code-dispatch-log` 上的第二个监听器，把同一套上限、替换流水线与尽力而为的回退应用到每个 `run_code` 子调用结果的持久化副本上（产物标签为 `dispatch`，按子调用 id 归档）。程序的值不受影响，因为它早已完整跨过 worker 边界；`read` 子调用同样设界：日志副本不是模型上下文，因此不会发生 read-again 循环，而 `read` 恰恰是最容易产生巨型日志的工具（[原理](../../../.agents/notes/implemented/feature/2026-07-26-code-dispatch-log-spill.zh.md)）。
+### 哪些结果会受影响
 
-## 范围
+策略只作用于最终、已接受且纯文本的结果。不超过上限的结果、包含任何非文本块的结果、嵌套复合调用、`read` 结果、被阻止的决策与已接受的值替换都会原样通过。此前已经发生的提供方级截断（例如 `web-fetch-http.maxBodyChars`）无法在此恢复——spill 文件保存的是工具实际返回的内容。
 
-该策略只能看到最终格式化的呈现结果，看不到工具的内部资源或规范值。如果提供方已经截断内容（例如 `web-fetch-http.maxBodyChars`），spill 产物保存的是工具返回的完整格式化结果，而非完整原始源。提供方／资源上限仍然是必需的，并且与该策略相互独立。`glob`/`grep` 负责对项级呈现结果执行 spill，因为渲染前仍然存在完整的已获取值；bash 流负责在获取时 spill。通用策略预先注册自己的 waterfall（瀑布式事件）监听器，然后再委托，因此无论插件加载顺序如何，普通工具自身的异步投影都会在通用字节限制之前完成。详见[工具输出 spill Agent Note](../../../.agents/notes/implemented/architecture/2026-07-08-tool-output-spill-files.zh.md)。
+### 尽力而为的故障行为
 
+缺少会话所有者、缺少 `ctx.spillStore` 后端或 `saveText` 拒绝时，会记录警告并返回原始结果。spill 失败绝不会把成功的调用变成错误，也绝不会隐藏内联结果。
+
+### 持久日志副本
+
+同样的上限也约束每个 `run_code` 子调用结果的会话日志副本：程序仍会收到完整值，只有日志副本被替换为预览与定位信息。过大的 `read` 子调用结果在此同样设界，因为日志副本不是模型上下文。

+
+本节解释该策略背后的设计决策；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+该策略刻意保持狭窄：它只决定**何时** spill，并组合通知。它不注册服务、不负责存储、也不负责预览机制——`dsh-output-retention` 的 `TextRetainer` 负责构建首尾预览。两个不变式塑造了代码：面向模型的替换永远不会超过 `maxInlineBytes`（先为通知预留字节成本），且 spill 失败永远不会改变工具调用的结果。
+
+### 两条分支
+
+`tools/post-execute` waterfall（瀑布式事件）监听器（以 `prepend` 注册、通过 `next()` 委托）约束面向模型的结果；`tools/code-dispatch-log` 监听器约束每个 `run_code` 子调用的持久日志副本。两者共享同一个替换辅助函数，因此两个投影字节一致。post-execute 分支跳过 `read` 以避免 read → spill → read 循环；dispatch-log 分支约束 `read` 子调用，因为日志副本不是模型上下文。

-The **`SpillStore`** (`ctx.spillStore`) defines WHAT a spill backend does — persist a tool's oversized text and return a model-facing locator plus retrieval guidance — without saying HOW.
+## Summary
 
-This package is one third of the spill capability, split so each concern evolves (and swaps) independently:
+`dsh-spill` lets any plugin or tool save oversized text through `ctx.spillStore` and receive an opaque locator, the exact byte count, and retrieval guidance the model can act on. It defines what a spill backend does, not how it stores — a deployment mounts a backend such as `dsh-spill-local` for real persistence, and the `dsh-spill-policy` plugin decides when a tool result is too large. Choose it when a deployment must keep oversized tool output retrievable without flooding the model's context. The service owns storage only: no retention policy, no tool-result replacement, and no retrieval or search API. A real storage failure rejects loudly, so the caller decides how to degrade.

+<a id="use-this-package"></a>
+## Use this package
+
+A composition that spills tool output mounts one spill backend — this package alone stores nothing — and the `dsh-spill-policy` plugin decides when to spill. Plugin and tool authors call `ctx.spillStore.saveText()` directly to persist text under the current session.
+
+### When to choose it
+
+Choose spill storage when a deployment needs to keep oversized tool output retrievable after the model has only seen a bounded preview — for example a fetched page body the model may want to read or grep later. You do not need this package when no tool in the composition produces results large enough to matter, or when the deployment has no local filesystem the model's tools can read; a backend whose locator is meaningful in that environment is a prerequisite.
+
+### Smallest working composition
+
+Mount a backend and the policy together; with `maxInlineBytes` set, any oversized plain-text tool result becomes a preview plus a locator automatically.
+
+```yaml
+- name: '@deepseek-ai/dsh-spill-local'
+- name: '@deepseek-ai/dsh-spill-policy'
+  config:
+    maxInlineBytes: 50000
+```
+
+### Saving text
+
+With a backend mounted, call `ctx.spillStore.saveText()` with the owning session, a source description, a suggested file name, and the full text:
+
+```text
+const ref = await ctx.spillStore.saveText({
+  owner: { sessionId: 'session-1' },
+  source: { toolName: 'web_fetch', callId: 'call-1', label: 'result' },
+  suggestedName: 'web_fetch.txt',
+  content: fullText,
+})
+```
+
+The returned `SpillRef` carries three fields: `locator`, an opaque model-facing handle the backend produces (a local file path for `dsh-spill-local`, possibly a URI or key for another backend); `bytes`, the exact UTF-8 byte count written; and `retrievalHint`, the guidance a consumer shows the model — for the local backend, read or grep the path. Consumers render the locator with the hint and never parse the locator itself.
+
+### Ownership and boundaries
+
+Storage is grouped by the owning session: forked sessions inherit existing locators from the seeded log without copying or re-owning them, and new spills after a fork use the child session id. `suggestedName` is only a hint — backends sanitize it to one safe segment and never trust it as a path. The service deliberately excludes what other packages own: retention and preview decisions (`dsh-output-retention`), when to spill (`dsh-spill-policy`), and retrieval or search (the backend's `retrievalHint` tells the model what to do with the locator).
+
+### Failures and recovery
+
+`saveText` rejects only on a real storage failure — permissions, no space left, or a backend that is down. The caller decides how to degrade: the shipped policy treats a rejection as best-effort, logs a warning, and keeps the original inline result, so a spill failure never turns a successful tool call into an error or hides content. If no backend is mounted, there is nothing to save; load `dsh-spill-local` or another backend in the composition.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the service; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The package is built on one separation and a deliberate minimum:
+
+- **Contract, implementation, and policy stay separate.** This package defines what a backend does (`saveText`); `dsh-spill-local` implements it; `dsh-spill-policy` decides when. Each concern evolves and swaps independently.
+- **One method, nothing else.** The seam owns no retention policy, no result replacement, and no retrieval or search API — those have owning packages.
+- **Reject, never silently degrade at the seam.** The caller owns degradation; the seam reports real storage failures.
+
+### Source map
+
+| File | Role |
 |---|---|
-| `@deepseek-ai/dsh-spill` (this) | Service Definition: abstract service + vocabulary types |
-| `@deepseek-ai/dsh-spill-local` | Service Provider: private session-scoped files on the host filesystem |
-| `@deepseek-ai/dsh-spill-policy` | Consumer: the tool-result policy that spills oversized final results |
+| [`src/index.ts`](src/index.ts) | Plugin entry: the abstract `SpillStore` service and its `saveText` contract |
+| [`src/types.ts`](src/types.ts) | Vocabulary: `SaveTextSpill`, `SpillRef`, branded `SpillLocator`, `SpillOwner`, `SpillSource` |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; contracts are enforced at the seam) |
 
-The split mirrors the shell/fs seams. A future remote or virtual backend (e.g. a `spill://…` URI, a database key, or a backend-specific retrieval tool) implements this Service Definition without touching the policy plugin.
+### Data model
 
-## Service API (`ctx.spillStore`)
+`SaveTextSpill` (owner, source, suggestedName, content) is the request; `SpillRef` (locator, bytes, retrievalHint) is the result. `SpillLocator` is a branded string so consumers cannot treat it as a path without the backend's intent; `SpillOwner.sessionId` is the save-time storage namespace, and `SpillSource` records the producing tool, call id, and label for readable filenames — descriptive only, never access control.
 
-| Member | Semantics |
-|---|---|
-| `saveText(input)` | Persist `input.content` verbatim; resolves with a `SpillRef` (opaque locator, exact bytes written, and retrieval hint). **Rejects on a real storage failure** (permissions, ENOSPC, backend unavailable) — the caller decides how to degrade. |
+### Lifecycle
 
-Storage is grouped by the request's `owner` session as a save-time namespace; the backend chooses its own private representation and may derive names from — never trust as a path — the caller's `suggestedName`. The seam owns storage only: NO retention policy (that is [`@deepseek-ai/dsh-output-retention`](../../util/output-retention)), NO tool-result replacement (that is `@deepseek-ai/dsh-spill-policy`), NO retrieval/search API (the backend's `retrievalHint` tells the model what to do with the locator).
+A backend subclasses `SpillStore` and loads as a plugin, registering as `ctx.spillStore`; one implementation per context, and a second load fails. Disposal releases the service. The abstract class itself registers nothing — this package contributes the contract and vocabulary only.
 
-## Vocabulary
+</details>
 
-`SaveTextSpill` (owner, source, suggestedName, content) is the request; `SpillRef` (locator, bytes, retrievalHint) is the result. `SpillLocator` is [branded](../../util/brand) and rendered to the model as an opaque string — a local path for `dsh-spill-local`, but a future backend may return a URI, key, or command token without changing policy/tool consumers. `SpillOwner.sessionId` is the save-time storage namespace: forked sessions inherit existing locators from the seeded log without copying or re-owning them, and new spills after the fork use the child session id. `SpillSource` records the producing `toolName`, `callId`, and `label` for backend naming and inspection, not access control. See `src/types.ts` for the full contracts.

+
+#### Future: executor spill-file integration
+
+The seam has only `saveText`; a save-file or link/copy path for existing executor spill files (for example normalizing bash temp files) and tool-owned spill for subagent rollouts remain deferred, per the [tool output spill decision](../../../.agents/notes/implemented/architecture/2026-07-08-tool-output-spill-files.md).

+#### Future: non-local backends and cleanup
+
+Remote or database backends for ACP or remote environments, and a cleanup or retention policy for old spill files (likely tied to session cleanup), remain open. A predictable, world-readable spill root would let other local users read spilled tool output, which is why the shipped backend keeps files private.

+## 使用本包
+
+需要 spill 工具输出的组合会挂载一个 spill 后端——仅本包本身不存储任何内容——并由 `dsh-spill-policy` 插件决定何时 spill。插件与工具作者直接调用 `ctx.spillStore.saveText()`，在当前会话下持久化文本。
+
+### 何时选择
+
+当部署需要在模型只看到有界预览之后仍可检索超大的工具输出时，选择 spill 存储——例如模型稍后可能想读取或搜索的抓取页面正文。当组合中没有工具会产生大到值得处理的输出，或部署没有模型工具可读取的本地文件系统时，你不需要本包；此时需要的是一个在该环境中定位信息有明确含义的后端。
+
+### 最小可用组合
+
+把后端与策略一起挂载；设置 `maxInlineBytes` 后，任何过大的纯文本工具结果都会自动变成预览加定位信息。
+
+```yaml
+- name: '@deepseek-ai/dsh-spill-local'
+- name: '@deepseek-ai/dsh-spill-policy'
+  config:
+    maxInlineBytes: 50000
+```
+
+### 保存文本
+
+挂载后端后，用所属会话、来源描述、建议文件名与完整文本调用 `ctx.spillStore.saveText()`：
+
+```text
+const ref = await ctx.spillStore.saveText({
+  owner: { sessionId: 'session-1' },
+  source: { toolName: 'web_fetch', callId: 'call-1', label: 'result' },
+  suggestedName: 'web_fetch.txt',
+  content: fullText,
+})
+```
+
+返回的 `SpillRef` 携带三个字段：`locator`，后端产生的不透明模型面向句柄（对 `dsh-spill-local` 是本地文件路径，对其他后端可能是 URI 或键）；`bytes`，写入的精确 UTF-8 字节数；`retrievalHint`，消费方展示给模型的指引——对本地后端而言是读取或搜索该路径。消费方按指引渲染定位信息，绝不自行解析定位信息。
+
+### 归属与边界
+
+存储按所属会话分组：fork 后的会话从种子日志继承既有定位信息，无需复制或更改归属，fork 后新产生的 spill 使用子会话 id。`suggestedName` 只是提示——后端会把它清理成单个安全路径段，绝不把它当作可信路径。该服务刻意排除其他包负责的内容：保留与预览决策（`dsh-output-retention`）、何时 spill（`dsh-spill-policy`），以及取回或搜索（后端的 `retrievalHint` 会告诉模型如何处理定位信息）。
+
+### 故障与恢复
+
+`saveText` 只在真实存储故障时拒绝——权限不足、磁盘已满或后端不可用。由调用方决定如何降级：随附策略把拒绝当作尽力而为处理，记录警告并保留原始内联结果，因此 spill 失败绝不会把成功的工具调用变成错误或隐藏内容。如果没有挂载后端，就没有可保存的目标；请在组合中加载 `dsh-spill-local` 或其他后端。

+
+- **约定、实现与策略保持分离。** 本包定义后端做什么（`saveText`）；`dsh-spill-local` 实现它；`dsh-spill-policy` 决定何时触发。各项关注点独立演进与替换。
+- **只有一个方法，别无其他。** 该 seam 不负责保留策略、结果替换或取回/搜索 API——那些都有各自的归属包。
+- **在 seam 处拒绝，绝不静默降级。** 降级由调用方负责；seam 报告真实存储故障。

+`SaveTextSpill`（owner、source、suggestedName、content）是请求；`SpillRef`（locator、bytes、retrievalHint）是结果。`SpillLocator` 是带品牌类型的字符串，消费方无法在未获后端意图的情况下把它当作路径；`SpillOwner.sessionId` 是保存时存储命名空间，`SpillSource` 记录产生 spill 的工具、调用 id 与标签，用于可读文件名——仅作描述，绝非访问控制。
 
-| 成员 | 语义 |

+### 生命周期
 
-存储操作以请求的 `owner` 会话作为保存时命名空间进行分组；后端自行选择私有表示，并可以从调用方的 `suggestedName` 派生名称，但绝不能将其当作可信路径。该 seam 只负责存储：不提供保留策略（由 [`@deepseek-ai/dsh-output-retention`](../../util/output-retention) 负责），不替换工具结果（由 `@deepseek-ai/dsh-spill-policy` 负责），也不提供取回/搜索 API（后端的 `retrievalHint` 会告诉模型如何使用定位信息）。
+后端继承 `SpillStore` 并以插件方式加载，注册为 `ctx.spillStore`；每个上下文只有一个实现，第二次加载会失败。dispose 会释放该服务。抽象类本身不注册任何内容——本包只提供约定与词汇。
 
-## 词汇
+</details>
 
-`SaveTextSpill`（owner、source、suggestedName、content）是请求；`SpillRef`（locator、bytes、retrievalHint）是结果。`SpillLocator` 是[带品牌类型](../../util/brand)的值，并以不透明字符串的形式呈现给模型；对 `dsh-spill-local` 而言它是本地路径，但未来的后端可以返回 URI、键或命令 token，无需修改策略／工具消费方。`SpillOwner.sessionId` 是保存时存储命名空间：fork 后的会话会从种子日志继承现有定位信息，无需复制或更改其归属；fork 后新产生的 spill 使用子会话 id。`SpillSource` 记录产生该 spill 的 `toolName`、`callId` 和 `label`，供后端命名和检查使用，不用于访问控制。完整约定见 `src/types.ts`。

-This family persists application data other than session event logs through named backends and typed data forms.
+## Summary
+
+The storage group gives a composition durable storage for everything that is not a session event log: workspace records, session sidecars, and other host-side application data. With it, host packages can persist typed records through a schema-validated domain form, choose between a human-readable JSON backend and a point-update SQLite backend, and receive a change event after every durable write. The family is optional and host-side only: it registers no tools, injects no prompts, and writes no session events, so the model and the agent loop never see it. Use it when the product keeps application state that must survive restarts; a composition with no such data can omit the whole group.

+存储组为组合提供会话事件日志以外一切数据的持久存储：工作区记录、会话伴随数据，以及其他宿主侧应用数据。借助它，宿主包可以经 schema 校验过的领域数据形式持久化类型化记录，在人类可读的 JSON 后端与支持定点更新的 SQLite 后端之间选择，并在每次持久写入后收到变更事件。本家族是可选项，且只面向宿主侧：它不注册工具、不注入提示词，也不写入会话事件，因此模型与 agent loop（智能体循环）永远不会看到它。当产品需要跨重启保留应用状态时使用它；没有任何此类数据的组合可以省略整个组。

 English | [中文](README.zh.md)
 
-Domain data form for the DeepSeek Harness storage hub: exposes the injectable `ctx.storageDomain` service and the matching `ctx.storage.domain` projection after every configured backend is registered. A domain is declared once with `defineDomain` (zod record schemas, `z.infer`-derived types), opened through `DomainFacility.open`, and served from authoritative in-memory state — reads are synchronous, writes serialize on one per-domain chain, reach durability on the routed backend first, then update memory and emit `domain/changed`. The opening consumer owns the handle's lifecycle and releases it with `Domain.close()` (idempotent; typically its own `ctx.effect` disposer); domains still open when the plugin unmounts are closed by the facility.
+## Summary
 
-Design rationale, open semantics, and the storage/domain layer split live in the [Agent Note](../../../.agents/notes/proposed/architecture/2026-07-24-domain-kv-storage-and-workspace.md).
+`dsh-storage-domain` is the typed way to use the storage family: an owning package declares a domain once — its name, format version, and zod record schemas — and host consumers open it over a routed backend and read and write records through `ctx.storageDomain`. Reads are synchronous from authoritative in-memory state; every write is durable before it resolves and emits a `domain/changed` event, so reads never diverge from the stored medium. It is the only consumer of the backend contract — product packages never touch backends directly. The layer is host-side only: it registers no tools, injects no prompts, and appends no session events, so the model and the agent loop never see it.

+## Use this package
+
+Use this package when a host package keeps durable, schema-validated records — workspace records, session sidecar metadata. The owning package declares the domain once; consumers open it and get synchronous reads and durable, change-emitting writes without ever touching a backend.
+
+### When to use it
+
+Choose it for any host-side data that must survive restarts and stay valid against a schema: the domain form validates every stored record at open, and every write is durable before it resolves. Avoid it when the data belongs in a session event log — the session persistence seam owns that surface.
+
+### Declaring a domain
+
+The owning package declares the domain once with `defineDomain` — name, version, and zod record schemas — and exports it. `defineDomain` fails loud at module load on a bad name, a non-integer version, or a global schema that accepts `null`.
+
+```text
+// Owning package, once:
+const workspaceSpec = defineDomain({
+  name: 'workspace',
+  version: 1,
+  tables: { workspaces: domainTable(workspaceRecordSchema) },
+})
+```
+
+### Opening and using a domain
+
+A consumer opens the declared domain through `ctx.storageDomain` and keeps the returned handle; reads are synchronous, writes are durable:
+
+```text
+const domain = await ctx.storageDomain.open(workspaceSpec)
+await domain.table('workspaces').put(id, { path: '/work/demo' })
+const record = domain.table('workspaces').get(id) // synchronous, from memory
+domain.table('workspaces').update(id, (r) => ({ ...r, path: newPath }))
+```
+
+The caller owns the handle's lifecycle and releases it with `domain.close()` when the feature shuts down (typically its own `ctx.effect` disposer); domains still open when the plugin unmounts are closed by the facility.
+
+### Routing domains to backends
+
+The domain plugin's configuration decides which backend serves which domain — never the hub. `backend` names the default route; `routes` overrides it per domain name. A route naming an unregistered backend fails loud at open with `backend-not-found`.
+
+| Field | Default | Meaning |
+|---|---|---|
+| `backend` | required | Default backend name for every domain without an explicit route |
+| `routes` | `{}` | Per-domain overrides: domain name → backend name |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-storage-domain) is the exhaustive source for every accepted field and its JSDoc.
+
+### Observable behavior and failures
+
+Every write resolves only after the backend acknowledges durability, and each emits one `domain/changed` event in write order. Failures carry stable `DomainError` codes: `already-open` (the name is open or still closing), `facet-unsupported` (the routed backend serves no `kv` facet), `invalid-record` (a stored record or global fails its schema, naming the table and key), `missing-key` (an `update` on an absent record), and `closed` (any use after close). Backend failures such as `version-mismatch` pass through unchanged.
+

+
+<a id="understand-the-implementation"></a>
+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+The domain layer is a single implementation, not an abstracted seam: consumers depend on this package and never touch backends directly, which concentrates all domain logic — schema validation, write serialization, change events — in one place instead of doubling it per backend.
+
+### Design concept
+
+- **The spec object is the single source of truth.** `defineDomain` pins the spec's literal types and validates its fields at the owning package's module load, before any medium is touched. Record schemas are zod so `z.infer` keeps consumer types un-duplicated; plugin `Config` stays schemastery.
+- **Memory is authoritative; the medium is the durable projection.** Reads are synchronous from validated in-memory state. Every write queues on one per-domain write chain: backend durability first, then memory mutation, then `domain/changed` — a rejected backend write leaves memory untouched, so reads never diverge from the medium.
+- **One write chain per domain.** `put`, `delete`, `update`, and `global.set` all queue on it; `update`'s transform runs at its chain slot, so concurrent updates never interleave. Records are plain immutable data — returned values are the stored objects themselves and must not be mutated in place.
+- **Writes emit after the commit point.** `domain/changed` is a notification, not a transaction participant: a throwing listener is contained with a logged warning rather than rejecting the already-durable write.
+
+### Open sequence
+
+`DomainFacility.open(spec)` runs a strict sequence, each step failing the whole call: reject a name already open or still closing (`already-open`); resolve the route (`backend-not-found`); require the `kv` facet (`facet-unsupported`); open the unit (backend `version-mismatch`/`malformed-medium` pass through); load and validate every stored record and the global against the spec's schemas (`invalid-record`); construct the domain. The caller owns the handle; the facility closes any domain left open when it unmounts, and a closed domain's name frees for reopening only after teardown completes.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `DomainFacility`, routing, `Config`, form mounting |
+| [`src/spec.ts`](src/spec.ts) | Domain declarations: `defineDomain`, `domainTable`, descriptor projection |
+| [`src/domain.ts`](src/domain.ts) | Open-domain runtime: write chain, table and global handles, close |
+| [`src/events.ts`](src/events.ts) | The `domain/changed` event vocabulary |
+| [`src/error.ts`](src/error.ts) | `DomainError` codes |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion: every `domain/changed` agrees with in-memory state |
+
+### Invariant
+
+The `storage-domain-invariant` companion registers the owned relationship: every `domain/changed` event must agree with the emitting domain's authoritative in-memory state at emission — a divergence means a write path skipped the chain or emitted a stale value.

+## 使用本包
+
+当宿主包需要持久、经过 schema 校验的记录——工作区记录、会话伴随元数据——时使用本包。由所属包声明一次领域；消费方打开它，即可获得同步读取与持久、发出变更事件的写入，而无需触碰任何后端。
+
+### 何时使用
+
+任何必须跨重启保留、并始终符合 schema 的宿主侧数据都适合它：领域数据形式在打开时校验每条已存记录，且每次写入在 resolve 前都已持久。当数据属于会话事件日志时请避免使用它——那是会话持久化 seam 的领域。
+
+### 声明领域
+
+所属包用 `defineDomain` 声明一次领域——名称、版本与 zod 记录 schema——并导出它。名称非法、版本不是非负整数、或全局 schema 接受 `null` 时，`defineDomain` 会在模块加载时明确报错。
+
+```text
+// Owning package, once:
+const workspaceSpec = defineDomain({
+  name: 'workspace',
+  version: 1,
+  tables: { workspaces: domainTable(workspaceRecordSchema) },
+})
+```
+
+### 打开并使用领域
+
+消费方通过 `ctx.storageDomain` 打开已声明的领域并持有返回的句柄；读取是同步的，写入是持久的：
+
+```text
+const domain = await ctx.storageDomain.open(workspaceSpec)
+await domain.table('workspaces').put(id, { path: '/work/demo' })
+const record = domain.table('workspaces').get(id) // synchronous, from memory
+domain.table('workspaces').update(id, (r) => ({ ...r, path: newPath }))
+```
+
+调用方拥有句柄的生命周期，并在功能关闭时用 `domain.close()` 释放它（通常作为其自身的 `ctx.effect` 资源释放函数）；插件卸载时，设施会关闭仍处于打开状态的领域。
+
+### 把领域路由到后端
+
+哪个后端服务哪个领域由领域插件的配置决定——绝非枢纽。`backend` 指定默认路由；`routes` 按领域名覆盖。路由到未注册后端的领域会在打开时以 `backend-not-found` 明确报错。
+

+## 理解实现
+
+<details>
+<summary>实现细节——点击展开</summary>
+
+领域层是单一实现，而非抽象化的 seam：消费方依赖本包、绝不直接触碰后端，这把所有领域逻辑——schema 校验、写入串行化、变更事件——集中在一处，而不是在每个后端重复一遍。
+
+### 设计理念
+
+- **spec 对象是唯一真源。** `defineDomain` 固定 spec 的字面类型，并在所属包的模块加载时、任何介质被触碰之前校验其字段。记录 schema 使用 zod，因此 `z.infer` 不会重复消费方类型；插件 `Config` 仍由 schemastery 负责。
+- **内存具有最终决定权；介质是持久投影。** 读取同步取自经过校验的内存状态。每次写入都在每个领域一条的写入链上排队：先到达后端持久状态，再变更内存，然后发出 `domain/changed`——被拒绝的后端写入不会触碰内存，因此读取永远不会与介质分叉。
+- **每个领域一条写入链。** `put`、`delete`、`update` 与 `global.set` 都在其上排队；`update` 的变换在链上自己的槽位运行，因此并发更新绝不会交错。记录是普通不可变数据——返回值就是已存对象本身，绝不能原地修改。
+- **写入在提交点之后发出。** `domain/changed` 是通知，不是事务参与者：抛异常的监听器会被兜住并记录警告，而不会让已经持久的写入被拒绝。
+
+### 打开顺序
+
+`DomainFacility.open(spec)` 按严格顺序执行，任一步骤失败都会让整个调用失败：拒绝已打开或仍在关闭的名称（`already-open`）；解析路由（`backend-not-found`）；要求 `kv` 分面（`facet-unsupported`）；打开单元（后端 `version-mismatch`／`malformed-medium` 透传）；加载并根据 spec 的 schema 校验每条已存记录与全局（`invalid-record`）；构造领域。调用方持有句柄；设施会在卸载时关闭任何仍打开的领域，已关闭领域的名称只在 teardown 完成后才能重新打开。
+

 # @deepseek-ai/dsh-storage-json

-JSON backend for the [storage hub](../storage/README.md), registered as backend `json`, serving two unit layouts:
+## Summary
 
-- **`single` (default)** — one human-readable `<unit>.json` file per unit under a configured root.
-- **`per-record`** — one version-stamped document per record at `<root>/<unit>/<table>/<key>.json` (plus `global.json`), so one write replaces one record instead of the whole unit; the unit is stateless (the directory is the state; `loadAll` re-reads the tree). Record keys must be path-safe (`[a-zA-Z0-9_-]+`); an unsafe key rejects.
+`dsh-storage-json` stores domain data as readable JSON under a configured root and registers as backend `json`. Its default `single` layout keeps one complete `<unit>.json` file per unit; its `per-record` layout keeps one version-stamped document per record. Both layouts publish each changed file atomically, while the domain layer orders calls. Choose it when operators need inspectable files and the selected layout fits the write volume; choose SQLite for larger or highly concurrent data. The backend is host-side only and contributes no prompt, tool, or schema.

-- `single` layout: the in-memory unit state is authoritative; every write primitive republishes the whole file via temp-write + fsync + atomic `rename()` replace. A unit file is always the complete current net state — legibility is this backend's reason to exist; scale is the SQLite backend's job.
-- A missing file (or unit directory, for `per-record`) opens as an empty unit and materializes on the first write. In `single` layout a foreign or unparsable file rejects with `malformed-medium`, and a stored version differing from the descriptor rejects with `version-mismatch` (no migration, pre-release stance). In `per-record` layout the contract is per record instead: a document that is malformed or stamped with another version reads as an absent record, so one bad or stale file never bricks the unit, and a version bump discards stale records rather than rejecting the whole unit.
-- An empty `per-record` tree bootstraps its declared-table records from a legacy `<unit>.json` whole-unit file and retains that file unchanged. Any new-layout document path in a declared table, or `global.json` for a declared global, suppresses the bootstrap for the whole unit even when the document is unreadable or stale; absent records remain absent instead of being filled from legacy state.
-- Write ordering across calls belongs to the caller (the domain layer's write chain); each single call is atomic and durable once resolved.

-## Config
+<a id="use-this-package"></a>
+## Use this package
 
-| Key | Type | Default | Meaning |
-| --- | --- | --- | --- |
-| `root` | string | required — no default (a cwd fallback would scatter files) | Directory holding unit files; created `0o700` on demand |
+Use this package when a composition needs readable, editable JSON storage. Route the relevant domains to backend `json`; each domain specification selects the `single` or `per-record` layout.
 
+### When to choose it
+
+Choose the default `single` layout for small units that benefit from one complete, pretty-printed file. Choose `per-record` when point writes should replace only one record document. Choose the SQLite backend when data is large, writes are frequent, or multiple records need transactional updates.
+
+### Configuration
+
+The only plugin field is `root`, which holds the unit files and directories. It is required because the backend does not fall back to `process.cwd()`. The backend creates the root with mode `0o700` on demand. A domain specification selects its layout; this plugin has no layout override.
+
+```yaml
+- name: '@deepseek-ai/dsh-storage'
+- name: '@deepseek-ai/dsh-storage-json'
+  config:
+    root: /var/lib/dsh/data
+- name: '@deepseek-ai/dsh-storage-domain'
+  config:
+    backend: json
+```
+
+| Field | Default | Meaning |
+|---|---|---|
+| `root` | required | Directory holding `<unit>.json` files and `<unit>/` trees; created `0o700` on demand |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-storage-json) is the exhaustive source for every accepted field and its JSDoc.
+
+### Observable behavior
+
+A missing `single` file or `per-record` directory opens as an empty unit and materializes on the first write. In `single`, malformed content rejects with `malformed-medium`, and a different stored version rejects with `version-mismatch`. In `per-record`, each malformed, unreadable, or differently versioned document reads as an absent record, so one bad document does not reject the unit. Record keys must match `[a-zA-Z0-9_-]+`; an unsafe key rejects before any file operation. Every resolved write is durable, and operations after close reject with `closed`.
+
+An empty `per-record` tree can initialize its declared tables from a valid `<root>/<unit>.json` whole-unit document. The backend leaves that source file unchanged. Any document path in a declared table, or a declared `global.json`, suppresses this initialization for the complete unit, even if that document is unreadable or stale.
+

+<a id="understand-the-implementation"></a>
+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+The two layouts share atomic publication but assign state ownership differently. `single` owns an in-memory unit projection; `per-record` treats its directory tree as authoritative.
+
+### Design concept
+
+- **`single` keeps memory authoritative.** Each write changes the in-memory unit, serializes its complete state, and atomically replaces `<unit>.json`. A failed publish restores the prior in-memory value.
+- **`per-record` keeps the directory authoritative.** Each put or delete changes one `<unit>/<table>/<key>.json` document, and `loadAll()` rereads the tree. Each document stamps the unit version and carries one record value.
+- **Publication is durable per call.** A write uses a temporary file, fsync, atomic `rename()` replacement, and a parent-directory fsync on POSIX. The domain layer's write chain supplies ordering across calls.
+
+### File formats
+
+A `single` document carries the unit identity, global singleton, and all tables:
+
+```json
+{
+  "unit": { "name": "workspace", "version": 1 },
+  "global": null,
+  "tables": { "workspaces": { "<key>": { "path": "/work/demo" } } }
+}
+```
+
+A `per-record` table document at `<root>/<unit>/<table>/<key>.json` has the form `{ "version": 1, "record": <value> }`; the optional global value uses `<root>/<unit>/global.json`. The format version comes from the domain specification.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: backend registration, `root` config, unit open/close table |
+| [`src/single-unit.ts`](src/single-unit.ts) | One `single` unit: authoritative memory, write primitives, publish rollback |
+| [`src/per-record-unit.ts`](src/per-record-unit.ts) | One `per-record` unit: tree reads, path-safe records, and one-document writes |
+| [`src/format.ts`](src/format.ts) | Whole-unit and record serialization with version validation |
+| [`src/atomic.ts`](src/atomic.ts) | Atomic file replacement: temp write, fsync, rename, directory fsync |

The mitigation is configuration — point `routes` at the SQLite backend — not a change to this package.

-- **`per-record`**——每个记录一个带版本戳的文档，位于 `<root>/<unit>/<table>/<key>.json`（外加 `global.json`），一次写入只替换一条记录而不是整个单元；该单元无状态（目录即状态，`loadAll` 重扫目录树）。记录键必须路径安全（`[a-zA-Z0-9_-]+`）；不安全键会被拒绝。
+`dsh-storage-json` 在配置的根目录下把领域数据存为可读 JSON，并注册为后端 `json`。默认的 `single` 布局为每个单元保存一份完整的 `<unit>.json` 文件；`per-record` 布局为每条记录保存一份带版本戳的文档。两种布局都以原子方式发布每个变更文件，领域层负责安排调用顺序。当运维方需要可检查文件且所选布局适合写入量时选择它；对于更大或高并发的数据则选择 SQLite。本后端只面向宿主侧，不贡献提示词、工具或 schema。

-- `single` 布局：内存中的单元状态具有最终决定权；每个写入原语都会通过临时文件写入 + fsync + 原子 `rename()` 替换重新发布整个文件。单元文件始终是完整的当前状态：可读性是该后端存在的理由，规模问题则属于 SQLite 后端。
-- 缺失文件（`per-record` 时是缺失单元目录）会作为空单元打开，并在第一次写入时物化。`single` 布局下外来或无法解析的文件以 `malformed-medium` 拒绝；已存版本与描述符不同时以 `version-mismatch` 拒绝（预发布立场，不迁移）。`per-record` 布局的契约改为按记录：畸形或版本戳不符的文档读作"无此记录"，单个坏文件或过期文件不会拖垮整个单元，版本升级按记录丢弃过期行而不是拒绝整个单元。
-- 空的 `per-record` 目录树会从旧 `<unit>.json` 整单元文件引导其已声明表的记录，并原样保留旧文件。已声明表中只要存在任意新布局文档路径，或已声明 global 对应的 `global.json` 存在，就会对整个单元禁用引导，即使该文档不可读或版本陈旧；缺失记录仍保持缺失，不从旧状态补入。

-| --- | --- | --- | --- |
-| `root` | string | 必填，无默认值（cwd 回退会让文件散落各处） | 保存单元文件的目录；按需以 `0o700` 创建 |
+当组合需要可读、可编辑的 JSON 存储时使用本包。把相关领域路由到 `json` 后端；每个领域规范选择 `single` 或 `per-record` 布局。
 
+### 何时选择
+
+小型单元需要一份完整、美化打印的文件时，选择默认的 `single` 布局。定点写入只应替换一份记录文档时，选择 `per-record`。当数据量大、写入频繁或多条记录需要事务更新时，选择 SQLite 后端。
+
+### 配置
+
+唯一的插件字段是 `root`，用于保存单元文件与目录。它是必填项，因为本后端不回退到 `process.cwd()`。后端按需以 `0o700` 模式创建根目录。领域规范选择其布局；本插件不提供布局覆盖项。
+
+```yaml
+- name: '@deepseek-ai/dsh-storage'
+- name: '@deepseek-ai/dsh-storage-json'
+  config:
+    root: /var/lib/dsh/data
+- name: '@deepseek-ai/dsh-storage-domain'
+  config:
+    backend: json
+```
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `root` | 必填 | 保存 `<unit>.json` 文件与 `<unit>/` 目录树的目录；按需以 `0o700` 创建 |
+
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-storage-json)是每个受支持字段及其 JSDoc 的穷尽式真源。
+
+### 可观察行为
+
+缺失的 `single` 文件或 `per-record` 目录会作为空单元打开，并在第一次写入时物化。在 `single` 中，畸形内容以 `malformed-medium` 拒绝，不同的已存版本以 `version-mismatch` 拒绝。在 `per-record` 中，每份畸形、不可读或版本不同的文档都读作记录不存在，因此单个坏文档不会使单元被拒绝。记录键必须匹配 `[a-zA-Z0-9_-]+`；不安全的键在任何文件操作前被拒绝。每次已完成的写入都已持久化，关闭后的操作以 `closed` 拒绝。
+
+空的 `per-record` 目录树可以从有效的 `<root>/<unit>.json` 整单元文档初始化其已声明表。后端保持该源文件不变。已声明表中只要存在任意文档路径，或存在已声明的 `global.json`，就会对整个单元禁止该初始化，即使该文档不可读或版本陈旧。

+## 理解实现
+
+<details>
+<summary>实现细节——点击展开</summary>
+
+两种布局共享原子发布机制，但以不同方式确定状态所有权。`single` 拥有一份内存单元投影；`per-record` 把目录树视为权威状态。
+
+### 设计理念
+
+- **`single` 以内存为权威状态。** 每次写入都会更改内存单元、序列化其完整状态，并以原子方式替换 `<unit>.json`。发布失败会恢复先前的内存值。
+- **`per-record` 以目录为权威状态。** 每次 put 或 delete 都会更改一个 `<unit>/<table>/<key>.json` 文档，`loadAll()` 则重新读取目录树。每份文档都带有单元版本戳与一条记录值。
+- **每次调用都持久发布。** 写入过程使用临时文件、fsync、原子 `rename()` 替换，并在 POSIX 上 fsync 父目录。领域层写入链负责安排跨调用的顺序。
+
+### 文件格式
+
+`single` 文档携带单元标识、全局单例与所有表：
+
+```json
+{
+  "unit": { "name": "workspace", "version": 1 },
+  "global": null,
+  "tables": { "workspaces": { "<key>": { "path": "/work/demo" } } }
+}
+```
+
+`per-record` 表文档位于 `<root>/<unit>/<table>/<key>.json`，形式为 `{ "version": 1, "record": <value> }`；可选的全局值使用 `<root>/<unit>/global.json`。格式版本来自领域规范。

 English | [中文](README.zh.md)
 
-SQLite backend for the [storage hub](../storage/README.md): registers as backend `sqlite`, serving the `kv` facet over one `node:sqlite` database file (or `:memory:`). Design and trade-offs: [domain KV storage Agent Note](../../../.agents/notes/proposed/architecture/2026-07-24-domain-kv-storage-and-workspace.md).
+## Summary
 
-## Storage model
+`dsh-storage-sqlite` is a storage backend that hosts every routed unit in one SQLite database file, storing each record as one JSON document per row, registered as backend `sqlite`. A single record update touches exactly one row, which is what makes this the right medium for high-frequency, point-sized writes. Choose it when a domain's data changes often or the deployment prefers one queryable database; choose the JSON backend when the data should be readable as plain files. The backend is host-side only: it contributes no prompt, tool, or schema, so the model and the agent loop never see it.
 
-Document-per-row: each unit table becomes a physical `"u_<unit>_<table>" (key TEXT PRIMARY KEY, value TEXT)` STRICT table whose `value` is the record's JSON text, so one key updates one row (the reason to route a high-churn domain here instead of the JSON backend). Unit identity lives in two metadata tables — `units` stamps each unit's format version at first open and rejects a differing descriptor with `version-mismatch`; `unit_globals` holds each unit's global singleton row. The physical layout version lives in `PRAGMA user_version`; any other stamped value rejects (unreleased format, no migrations). Unit and table names are validated against the hub's `UNIT_NAME_RE` before they reach DDL, so no external input is ever interpolated into SQL identifiers.
+## Table of Contents
 
-Every write primitive is a single prepared statement — SQLite's per-statement atomicity satisfies the KV contract without explicit transactions, and write ordering stays the caller's responsibility (the domain layer's write chain). Missing directories and database files are created owner-only (`0o700`/`0o600`), matching the session-persistence SQLite backend.

-## Configuration (schemastery)
+-----
 
-```ts
-interface Config {
-  path: string   // SQLite database file path, or ':memory:' for an in-process DB
-  journalMode?: 'wal' | 'delete' | 'truncate' | 'persist'   // journal_mode pragma; default 'wal'
-}
+<a id="use-this-package"></a>
+## Use this package
+
+Use this package when a composition keeps frequently updated domain data in one database: route the relevant domains to this backend and each unit materializes as tables in the configured database file.
+
+### When to choose it
+
+Choose it when writes are frequent and point-sized — each key maps to exactly one row, so updating one record touches one row instead of rewriting a whole file. Choose the JSON backend when humans inspect or edit the stored data as plain files. The synchronous `node:sqlite` driver blocks the JavaScript thread for the duration of each single-statement call, which is fine at domain-data scale but worth accounting for at high write rates.
+
+### Configuration
+
+Two fields: the database path and the journal mode. `:memory:` opens an in-process database whose contents disappear with the process.
+
+```yaml
+- name: '@deepseek-ai/dsh-storage'
+- name: '@deepseek-ai/dsh-storage-sqlite'
+  config:
+    path: /var/lib/dsh/data.db
+- name: '@deepseek-ai/dsh-storage-domain'
+  config:
+    backend: sqlite
 ```
 
+| Field | Default | Meaning |
+|---|---|---|
+| `path` | required | SQLite database file path, or `:memory:` |
+| `journalMode` | `wal` | Journal mode: `wal`, `delete`, `truncate`, or `persist` |
+
+`wal` suits local disks; a rollback-journal mode (`delete`/`truncate`/`persist`) fits filesystems where WAL's shared-memory files do not work, such as network mounts. The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-storage-sqlite) is the exhaustive source for every accepted field and its JSDoc.
+
+### Observable behavior
+
+Missing directories and database files are created owner-only (`0o700`/`0o600`); an existing database keeps its modes. A unit whose stored format version differs from its descriptor rejects `version-mismatch`, and a database stamped with a physical layout version other than the current one rejects outright — no migration, pre-release stance. Failures carry stable `StorageError` codes, and writes are durable once resolved.
+
+-----
+
+<a id="understand-the-implementation"></a>
+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+The backend is a document-per-row layout over one `node:sqlite` connection, designed so a per-key update is a single prepared statement.
+
+### Design concept
+
+- **Document per row.** Each unit table becomes a physical STRICT table `u_<unit>_<table> (key TEXT PRIMARY KEY, value TEXT)` whose `value` column holds the record's JSON text; the global singleton lives in a shared `unit_globals` table. One key update touches exactly one row — the reason to route a high-churn domain here.
+- **Single-statement atomicity.** Every write primitive is one prepared statement, so SQLite's per-statement atomicity satisfies the KV contract without explicit transactions; write ordering stays the caller's responsibility (the domain layer's write chain).
+- **Names validated before DDL.** Unit and table names must match `UNIT_NAME_RE` before they reach DDL, so no external input is ever interpolated into SQL identifiers.
+- **Versions fail loud.** The physical layout version lives in `PRAGMA user_version` (fresh databases stamp it last); unit format versions live in the `units` table. Any other stamped value rejects — no migrations.
+
+### Open sequence
+
+Opening the database mirrors the session-persistence SQLite backend: `mkdir` the parent `0o700`, exclusively create a missing file `0o600`, apply `PRAGMA foreign_keys = ON` and the journal mode, check `user_version`, create the `units` and `unit_globals` metadata tables, and stamp fresh databases last so a failure leaves the medium unstamped.
+

-[存储中心](../storage/README.zh.md)的 SQLite 后端：注册为后端 `sqlite`，通过一个数据库提供 `kv` facet；该数据库由 `node:sqlite` 操作，可以是单个文件，也可以是 `:memory:`。设计与取舍见[领域 KV 存储 Agent Note](../../../.agents/notes/proposed/architecture/2026-07-24-domain-kv-storage-and-workspace.zh.md)。
+## 概述
 
-## 存储模型
+`dsh-storage-sqlite` 是一个存储后端：把每个已路由单元托管在同一个 SQLite 数据库文件中，每条记录按行存储一份 JSON 文档，注册为后端 `sqlite`。单条记录更新恰好触碰一行，这正是它适合高频定点写入的原因。当领域数据变动频繁、或部署偏好单一可查询数据库时选择它；当数据需要以纯文本文件形式可读时选择 JSON 后端。本后端只面向宿主侧：它不贡献提示词、工具或 schema，因此模型与 agent loop（智能体循环）永远不会看到它。
 
-每行一个文档：每个单元表都会成为一个物理 STRICT 表 `"u_<unit>_<table>" (key TEXT PRIMARY KEY, value TEXT)`，其中 `value` 是记录的 JSON 文本，因此一个 key 只更新一行（高频变更领域路由到这里而非 JSON 后端的原因）。单元标识位于两个元数据表中：`units` 在单元首次打开时标记其格式版本，描述符不同时以 `version-mismatch` 拒绝；`unit_globals` 保存每个单元的全局单例行。物理布局版本位于 `PRAGMA user_version`；其他任何标记值都会被拒绝（未发布格式，不迁移）。单元名和表名在进入 DDL 之前依据中心的 `UNIT_NAME_RE` 进行验证，因此不会把外部输入插值到 SQL 标识符中。
+## 目录
 
-每个写入原语都是一条预处理语句：SQLite 的逐语句原子性无需显式事务即可满足 KV 约定，写入顺序仍由调用方负责（领域层写入链）。缺失目录和数据库文件会以仅所有者可访问的权限创建（`0o700`／`0o600`），与会话持久化 SQLite 后端一致。

-## 配置（schemastery）
+-----
 
-```ts
-interface Config {
-  path: string   // SQLite database file path, or ':memory:' for an in-process DB
-  journalMode?: 'wal' | 'delete' | 'truncate' | 'persist'   // journal_mode pragma; default 'wal'
-}
+<a id="use-this-package"></a>
+## 使用本包
+
+当组合把频繁更新的领域数据保存在一个数据库中时使用本包：把相关领域路由到此后端，每个单元即作为表物化在配置的数据库文件中。
+
+### 何时选择
+
+当写入频繁且为定点更新时选择它——每个键恰好映射到一行，因此更新一条记录只触碰一行，而不是重写整个文件。当人类需要以纯文本文件查看或编辑已存数据时选择 JSON 后端。同步的 `node:sqlite` 驱动会在每条单语句调用期间阻塞 JavaScript 线程，这在领域数据规模下可以接受，但高写入率时值得纳入考量。
+
+### 配置
+
+两个字段：数据库路径与 journal mode。`:memory:` 打开一个进程内数据库，其内容随进程消失。
+
+```yaml
+- name: '@deepseek-ai/dsh-storage'
+- name: '@deepseek-ai/dsh-storage-sqlite'
+  config:
+    path: /var/lib/dsh/data.db
+- name: '@deepseek-ai/dsh-storage-domain'
+  config:
+    backend: sqlite
 ```
 
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `path` | 必填 | SQLite 数据库文件路径，或 `:memory:` |
+| `journalMode` | `wal` | Journal mode：`wal`、`delete`、`truncate` 或 `persist` |
+
+`wal` 适合本地磁盘；回滚日志模式（`delete`／`truncate`／`persist`）适合 WAL 共享内存文件不可用的文件系统，例如网络挂载。生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-storage-sqlite)是每个受支持字段及其 JSDoc 的穷尽式真源。
+
+### 可观察行为
+
+缺失的目录与数据库文件会以仅所有者可访问的权限创建（`0o700`／`0o600`）；已有数据库保持其既有模式。已存格式版本与描述符不同的单元拒绝 `version-mismatch`，盖有非当前物理布局版本的数据库会直接拒绝——不做迁移，预发布立场。失败携带稳定的 `StorageError` 代码，写入 resolve 后即已持久。

+
+### 设计理念
+
+- **每行一份文档。** 每个单元表都变成一张物理 STRICT 表 `u_<unit>_<table> (key TEXT PRIMARY KEY, value TEXT)`，其 `value` 列保存记录的 JSON 文本；全局单例存放在共享的 `unit_globals` 表中。一个键的更新恰好触碰一行——这就是把高频变更领域路由到这里的原因。
+- **单语句原子性。** 每个写入原语都是一条预处理语句，因此 SQLite 的逐语句原子性无需显式事务即可满足 KV 约定；写入顺序仍由调用方负责（领域层的写入链）。
+- **名称在 DDL 之前校验。** 单元名与表名在进入 DDL 之前必须匹配 `UNIT_NAME_RE`，因此任何外部输入都不会被插值进 SQL 标识符。
+- **版本明确报错。** 物理布局版本存放在 `PRAGMA user_version`（全新数据库最后盖戳）；单元格式版本存放在 `units` 表中。任何其他已标记值都会被拒绝——不做迁移。

+### 打开顺序
+

-Storage hub (`ctx.storage`) for non-session data: a named backend registry plus mounted data-form facilities. The hub performs no IO itself — backends own media, and data forms own semantics. The [storage family overview](../README.md) maps those packages; the [domain KV storage Agent Note](../../../.agents/notes/proposed/architecture/2026-07-24-domain-kv-storage-and-workspace.md) records the design rationale.
+## Summary
 
-## Shape
+Mount `dsh-storage` to give a composition durable, non-session storage: it is the hub where backends and data forms connect, so host packages can read and write typed records through `ctx.storageDomain`. The hub performs no IO itself — backends own the medium (a file-tree root, a database file), and data forms own semantics — so a composition pairs it with one or more backends and the domain form. It is optional and host-side only: it registers no tools, injects no prompts, and writes no session events, so the model and the agent loop never see it. Choose it whenever any package in the composition needs durable data that is not a session event log; a composition with no such data can omit the whole group.
 
-- `ctx.storage.backend` — name → backend table. Multiple backends stay mounted side by side (`json`, `sqlite`); which backend serves a consumer is that consumer's configuration (the domain layer's route table), never a hub-global choice. `register()` returns the disposer; duplicate names and unknown lookups fail loud.
-- `ctx.storage.mount(form, facility)` / `ctx.storage.form(form)` — data-form mounting. `StorageForms` is merge-extensible; the domain layer merges `domain` and is reached as `ctx.storage.domain`.
-- A backend owns one medium and exposes the data-shape facets it supports. `kv` is the current facet; `src/backend.ts` owns its exact contract.

+### When to use it
+
+Mount the hub whenever any package in the composition persists data that is not a session event log — workspace records, session sidecars. It is required by the domain form and both shipped backends, so the storage rows of a composition are `storage` plus a backend plus `storage-domain`. Skip the whole group when nothing stores such data; the agent loop never needs it.
+
+### A minimal composition
+
+```yaml
+- name: '@deepseek-ai/dsh-storage'
+- name: '@deepseek-ai/dsh-storage-json'
+  config:
+    root: /var/lib/dsh/data
+- name: '@deepseek-ai/dsh-storage-domain'
+  config:
+    backend: json
+```
+
+With these rows, the `json` backend registers itself and the `domain` data form mounts; a consumer such as `dsh-workspace` then opens its domain over the routed backend and reads and writes records through `ctx.storageDomain`. Several backends can stay mounted side by side; which backend serves which domain is the domain form's configuration, never a hub-wide choice.
+
+### What you get
+
+- A mounted backend resolves by name, so a composition with both shipped backends can route each domain to either medium by configuration.
+- A mounted data form resolves as `ctx.storage.<form>`; the domain form is additionally served directly as `ctx.storageDomain`.
+- Misconfiguration fails loud with a stable `StorageError` code instead of silently deferring: an unknown backend name, a form read before its owner mounts, or a duplicate registration all throw.
+
+### Failures and recovery
+
+- `backend-not-found` — the domain form routes to a backend that is not mounted; add the backend package. The form waits for every configured backend to register, so row order is not a failure mode.
+- `form-not-mounted` — a consumer reads `ctx.storage.domain` before `dsh-storage-domain` loads; mount the domain row before the consumer.
+- `duplicate-backend` / `duplicate-mount` — the same name or form registers twice; that is a composition bug and fails loud.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+The hub is a pure registration table with two faces, designed so backends and data forms stay replaceable without the hub knowing their internals.
+
+### Design concept
+
+- **Backends own media, data forms own semantics.** The hub never performs IO; it only holds the name → backend table and the form-name → facility map. Backend packages register their medium owner, data-form packages mount their facility, and neither needs the other's details.
+- **Multiple backends stay side by side.** Which backend serves which consumer is the consumer's configuration (the domain form's route table), never a hub-global either-or.
+- **Registration and mounting are effects.** `register()` and `mount()` return disposers; disposal removes only that registration's contribution, and does not close the backend — the owning plugin closes it after unregistering.
+- **Activation cannot race registration.** Each backend plugin also publishes a lifecycle-only service key (`storage.backend.<name>`); form providers inject those keys, so the domain form activates only after every configured backend registers, while callers still resolve backends by name through the hub.
+
+### The backend contract
+
+[`src/backend.ts`](src/backend.ts) is the normative contract for backend implementers, checked clause by clause by the shared conformance suite in `tests/contract.ts`. A backend owns exactly one medium and exposes optional data-shape facets; `kv` is the only facet, and opening a unit yields a versioned, globally-singleton schema handle whose single calls are atomic and durable once resolved. Unit and table names must match `UNIT_NAME_RE`; record keys are arbitrary strings that never reach file paths. The unit does not serialize concurrent writes — ordering belongs to the caller — and a stored version differing from the descriptor rejects `version-mismatch` (no migration).
+
+### Source map

-非会话数据的存储中心（`ctx.storage`）：具名后端注册表加已挂载的数据形式设施。中心自身不执行 IO：后端拥有介质，数据形式拥有语义。[存储家族概述](../README.zh.md)列出了这些包；[领域 KV 存储 Agent Note](../../../.agents/notes/proposed/architecture/2026-07-24-domain-kv-storage-and-workspace.zh.md)记录了设计理由。
+## 概述
 
-## 结构
+挂载 `dsh-storage` 即可为组合提供持久的非会话存储：它是后端与数据形式交汇的枢纽（hub），宿主包因此可以通过 `ctx.storageDomain` 读写类型化记录。枢纽自身不执行任何 IO——后端拥有介质（一个文件树根目录、一个数据库文件），数据形式拥有语义——因此组合会把它与一个或多个后端以及领域数据形式一起挂载。它是可选项，且只面向宿主侧：不注册工具、不注入提示词，也不写入会话事件，因此模型与 agent loop（智能体循环）永远不会看到它。只要组合中任何包需要会话事件日志以外的持久数据就选择它；没有任何此类数据的组合可以省略整个组。
 
-- `ctx.storage.backend`：名称 → 后端表。多个后端并排保持挂载（`json`、`sqlite`）；为消费方提供服务的后端由该消费方自身的配置决定（领域层的路由表），绝非中心的全局选择。`register()` 返回资源释放函数；注册重复名称或查找未知名称时都会明确报错。
-- `ctx.storage.mount(form, facility)`／`ctx.storage.form(form)`：数据形式挂载。`StorageForms` 可通过合并扩展；领域层合并 `domain`，并通过 `ctx.storage.domain` 访问。
-- 后端拥有一种介质，并公开其支持的数据形状**分面**。当前分面为 `kv`；`src/backend.ts` 负责定义其确切约定。

+## 使用本包
+
+使用本包为组合提供持久的非会话存储：把它与后端和数据形式包一起挂载，宿主包即可通过 `ctx.storageDomain` 读写经过校验的记录。枢纽自身不增加任何可观察行为——它是让整个家族运转起来的交汇点——以下内容就是组合从它得到的一切。
+
+### 何时使用
+
+当组合中任何包需要持久化会话事件日志以外的数据——工作区记录、会话伴随数据——时就挂载枢纽。领域数据形式与两个内置后端都依赖它，因此组合的存储行是 `storage` 加一个后端加 `storage-domain`。没有任何此类数据的组合可以省略整个组；agent loop 永远不需要它。
+
+### 最小组合
+
+```yaml
+- name: '@deepseek-ai/dsh-storage'
+- name: '@deepseek-ai/dsh-storage-json'
+  config:
+    root: /var/lib/dsh/data
+- name: '@deepseek-ai/dsh-storage-domain'
+  config:
+    backend: json
+```
+
+这些行加载后，`json` 后端注册自身、`domain` 数据形式挂载；诸如 `dsh-workspace` 之类的消费方随后在已路由后端上打开自己的领域，并通过 `ctx.storageDomain` 读写记录。多个后端可以并排保持挂载；哪个后端服务哪个领域由领域数据形式的配置决定，绝非枢纽的全局选择。
+
+### 你能得到什么
+
+- 已挂载的后端按名称解析，因此同时挂载两个内置后端的组合可以把每个领域按配置路由到任一种介质。
+- 已挂载的数据形式解析为 `ctx.storage.<form>`；领域数据形式还直接以 `ctx.storageDomain` 对外服务。
+- 错误配置会以稳定的 `StorageError` 代码明确报错，而不是静默推迟：未知的后端名称、在其所有者挂载前读取数据形式、或重复注册都会抛出异常。
+
+### 失败与恢复
+
+- `backend-not-found`——领域数据形式路由到未挂载的后端；请添加后端包。数据形式会等待所有已配置后端注册，因此行序不会造成失败。
+- `form-not-mounted`——消费方在 `dsh-storage-domain` 加载前读取 `ctx.storage.domain`；请把领域行放在消费方之前。
+- `duplicate-backend`／`duplicate-mount`——同一名称或形式注册了两次；这是组合错误，会明确报错。
+
+-----
+
+<a id="understand-the-implementation"></a>
+## 理解实现
+
+<details>
+<summary>实现细节——点击展开</summary>
+
+枢纽是一张纯注册表，拥有两个面，设计目标是后端与数据形式可以独立替换，而枢纽无需了解它们的内部实现。
+
+### 设计理念
+
+- **后端拥有介质，数据形式拥有语义。** 枢纽从不执行 IO；它只持有名称 → 后端表和形式名 → 设施表。后端包注册其介质所有者，数据形式包挂载其设施，双方都不需要对方的细节。
+- **多个后端并排共存。** 哪个后端服务哪个消费方由消费方自身的配置决定（领域数据形式的路由表），绝非枢纽全局的二选一。
+- **注册与挂载都是 effect。** `register()` 与 `mount()` 返回资源释放函数；释放只移除该次注册的贡献，且不会关闭后端——由所属插件在注销后关闭。
+- **激活不会与注册竞争。** 每个后端插件还会发布一个仅用于生命周期的服务键（`storage.backend.<name>`）；数据形式提供方注入这些键，因此领域数据形式只在所有已配置后端注册后激活，而调用方仍通过枢纽按名称解析后端。
+
+### 后端约定
+
+[`src/backend.ts`](src/backend.ts) 是后端实现者的规范性约定，由 `tests/contract.ts` 中的共享一致性套件逐条款检查。一个后端只拥有一种介质，并暴露可选的数据形状分面；`kv` 是唯一的分面，打开单元即可获得一个带版本、全局单例的 schema 句柄，其每次单独调用都是原子的，且 resolve 后即已持久。单元名与表名必须匹配 `UNIT_NAME_RE`；记录键是任意字符串，绝不进入文件路径。单元不对并发写入做串行化——顺序由调用方负责——介质上记录的版本与描述符不同时拒绝 `version-mismatch`（不做迁移）。

 # subagent/ — subagent capability family
 
 English | [中文](README.zh.md)
 
-This family lets an agent delegate work to child agents. Multiple named providers may coexist in one context.
+## Summary
+
+The subagent group is the delegation family: it lets an agent hand a task to a child agent, wait for or continue the child's work, and keep every child discoverable. One contract (`ctx.subagents`) serves any number of named providers, so a single composition can mix in-process children (fresh, or forked from the parent's completed history) with out-of-process children — an ACP agent, a real Codex or Claude Code installation, or a complete Harness runtime over the SDK. The model-facing tools expose delegation, follow-up, and listing to agents, and a parent can always see which children exist and whether they are live or stored. This page maps the group; each package README owns its package contract.

-The Codex and Claude Code packages are independent optional Profile Bundles. Install either or both with `dsh plugin --profile <name> add @deepseek-ai/dsh-subagent-codex @deepseek-ai/dsh-subagent-claude-code`, then restart that Profile; each package registers only its dormant Host provider. To grant a tool, copy a complete Agent Preset, remove `disabled` from each matching tool row, and start a new Session. Removing one package withdraws only that provider and its private runtime closure on the next Profile start.

-本家族允许一个 agent（智能体）将工作委派给子 agent。多个具名提供方可在同一上下文中共存。
+## 概述
+
+subagent 组是委派能力家族：它让 agent（智能体）把任务交给子 agent，等待或继续子 agent 的工作，并让每个子 agent 随时可被发现。一个约定（`ctx.subagents`）服务任意数量的具名提供方，因此单个组合可以混合进程内子 agent（全新启动，或从父级已完成历史派生）与进程外子 agent——ACP agent、真实 Codex 或 Claude Code 安装，或经 SDK 运行的完整 Harness 运行时。面向模型的工具向 agent 公开委派、后续消息与列举，父级总能看到存在哪些子级、它们在线还是仅存于存储。本页是组的映射；各包 README 负责各自的包约定。

-The ACP provider runs each subagent in a fresh subprocess and drives it as an Agent Client Protocol client. It is the out-of-process alternative to spawn and fork: the child has its own runtime, session, model configuration, and tools.
+## Summary
 
-## Start and ownership
+`dsh-subagent-acp` runs each delegated child in a fresh subprocess and drives it as an Agent Client Protocol client: the child gets its own runtime, session, model configuration, and tools, and it can be any ACP-compatible agent, not just Harness. It is the out-of-process alternative to the in-process spawn and fork backends, sharing only the parent session's working directory with the child. Each run spawns a fresh process, initializes an ACP session, sends the task, and collects the streamed final answer; permission prompts are auto-answered by configuration, so no human is needed. The parent receives only the child's final answer or a safe error — no intermediate messages or tool traffic crosses the boundary. Choose it when the child must be fully isolated from the parent harness and can speak ACP.
 
-`start(request)` resolves the child's working directory, then performs `spawn` → ACP `initialize` → `newSession` before it fulfills. Fulfillment therefore means a remote session is ready and ownership has transferred to the caller. A spawn, initialization, new-session, or pre-publication cancellation failure ordinarily rejects after the subprocess is reaped; when cleanup itself rejects, ordered safe facts preserve startup plus teardown for an ordinary failure, or teardown alone after cancellation, without claiming whole-tree quiescence. A working-directory resolution failure rejects before anything is spawned. Non-cancellation rejections expose only fixed provider, stage, and category facts in their Error message; the original failure remains on the internal cause chain and in Host diagnostics.
+## Table of Contents
 
-The working directory is the configured `cwd` override when set, else the delegating parent session's cwd — never the server process's own cwd, because one server process serves sessions from many workspaces. The parent-derived value must be an absolute path naming a directory the harness can enter (search permission — what a subprocess cwd needs), and the same resolved path becomes both the subprocess cwd and the ACP `session/new` workspace.

+- [Known Limitations and Deferred Work](#known-limitations-and-deferred-work)
+- [Dev Note](#dev-note)
 
-The returned run id is minted in the parent namespace. The child server's session id remains private to ACP wire calls because ACP guarantees it only within that fresh child process; using it as the parent lifecycle id could collide with another remote run or a local agent.
+-----
 
-After publication, the provider sends the prompt and collects streamed `agent_message_chunk` text into `SubagentResult.output`. A prompt/transport or early-process failure resolves with `stopReason: 'error'` and a safe `SubagentResult.diagnostic`; local cancellation resolves as `aborted` without failure detail. Partial assistant text remains in `output`, separate from the diagnostic.
+<a id="use-this-package"></a>
+## Use this package
 
-`dispose()` is idempotent. It removes the signal listener, requests ACP cancellation when possible, then runs this backend's own teardown ladder (`disposeAcpChild`) over the seam's verbs: close stdin and wait `disposeEofGraceMs` for cooperative quiescence, then invoke the handle's `terminate()` escalation (SIGTERM, the spawn grace, SIGKILL — Windows force-terminates directly) and await the subprocess owner's whole-tree exit proof. Every run uses a fresh process; process pooling is not implemented.
+Mount this provider when a composition needs a fully isolated, out-of-process child that speaks the Agent Client Protocol. The common path is explicit: mount the seam, mount this provider, and give it a command that starts an ACP agent.
 
-## Capabilities and context
+### When to choose it
 
-ACP advertises no start-time capabilities because this process cannot apply `request.agentOptions` or enforce the remote child's depth, tool filter, persona, or structured-output runtime. It also reports `inheritsParentContext: false`: the remote session starts fresh, and the only parent-derived input is the workspace cwd described above — no conversation context crosses the process boundary.
+Choose this backend when the child must run with its own runtime, model, and tools in a separate process — for example an ACP agent from another project — or when you want delegation that cannot touch the parent harness. Choose an in-process backend when the child must share the parent's composition or honor parent-enforced capabilities: this provider advertises no optional start-time capabilities, so the seam rejects requests for `agentOptions`, structured output, depth caps, tool filters, or personas rather than silently omitting them.

+### What you get
 
-| ACP | Harness | Additional diagnostic |
-|---|---|---|
-| `end_turn` | `completed` | None. |
-| `max_tokens` | `max-tokens` | Only a contributing permission decision. |
-| `refusal` | `refusal` | Only a contributing permission decision. |

-| `max_turn_requests` | `error` | `remote-limit` with the closed stop reason. |
-| unknown | `error` | Fixed `unknown`; the wire value is not copied. |
+A successful run returns the child's final streamed assistant text as the result output. The child's session, model, and tools come from the child process itself — the parent supplies only the task and the working directory. The stop reason maps `end_turn` to `completed`, `max_tokens` to `max-tokens`, `refusal` to `refusal`, `cancelled` to `aborted`, and every other value to `error`. A failed published run preserves partial assistant text in `output` and returns safe structured detail separately in `diagnostic`.
 
-## Failure diagnostics
+### Failure and recovery
 
-Failure diagnostics for generic error paths have a fixed field order:
+A spawn, initialization, or new-session failure rejects before publication, ordinarily after the child process is reaped. If cleanup also fails, the rejection preserves ordered safe startup and teardown facts without claiming whole-tree quiescence. Non-cancellation errors expose only fixed provider, stage, and category facts; the original failure stays on the internal cause chain and in Host diagnostics. After publication, a prompt, transport, or early-process failure resolves as `error` with a safe diagnostic, while local cancellation resolves as `aborted` without failure detail.
 
-```text
-Subagent failure (provider: ACP; stage: <stage>; category: <category>; stop reason: <reason>; exit code: <code>; signal: <signal>)
-```
+### Safe diagnostics
 
-Unavailable optional fields are omitted. The provider derives `initialize`, `new-session`, `prompt`, `process`, or `teardown` at the operation that owns the failure. Categories distinguish configuration, protocol or transport failure, process start/exit, remote limits, and the fixed unknown fallback. Exit code and signal come only from the managed subprocess outcome; stderr, exception messages, task text, tool input, paths, environment values, credentials, and protocol payloads never enter the diagnostic. The shared result boundary limits the complete text to 4096 UTF-8 bytes.
+A generic diagnostic uses one fixed line: `Subagent failure (provider: ACP; stage: <stage>; category: <category>; ...)`. Optional stop reason, exit code, and signal come only from closed protocol or managed-process facts. Stderr, exception text, task content, tool input, paths, environment values, credentials, and protocol payloads never enter the diagnostic; the shared result boundary limits it to 4096 UTF-8 bytes. A non-completed run that requested permission can add one fixed policy, tool-kind, and decision line. Successful runs and local cancellation omit it.
 
-When a run requested permission and did not complete, a fixed permission line records the configured policy, the ACP closed tool kind, and whether the provider allowed or denied it. Tool titles, raw input, locations, and option text are excluded. For `max-tokens`, `refusal`, or remote `aborted`, this is the complete diagnostic because the public stop reason already carries the terminal fact; generic error paths put it after the failure line. Successful results and local cancellation omit it. A permission-diagnosed remote `aborted` result remains `aborted`; foreground presentation includes its diagnostic, while the one-shot Job adapter classifies that diagnostic-bearing remote abort as failed instead of conflating it with local cancellation.

-The child spawns through the [`dsh-subprocess`](../../subprocess/subprocess/README.md) seam: credential-shaped ambient variables and ambient `DSH_*` names are removed by the shared scrub, then explicit `config.env` values merge after it (an intended `DEEPSEEK_API_KEY` survives, and a `DSH_*` deployment fact such as `DSH_PERMISSION_MODE` reaches the child the same way — the scrub drops only its stale ambient namesake), stderr is inherited to the parent's own stream, and disposal applies this plugin's EOF window before the subprocess-owned SIGTERM→SIGKILL escalation and whole-tree join. The ACP wire is the real serialization boundary; same-process subagent values are not defensively cloned.

-The package has no default export. Cordis loader unwrapping would otherwise hide the named `inject` metadata; see [postmortem 0001](../../../docs/postmortem/0001-acp-default-export-drops-inject.md).
+This section explains how the backend drives a child over ACP and where the observable behavior comes from; the full contract lives in [Use this package](#use-this-package).
 
+### Design concept
+
+- **Full process isolation.** Each child runs in a fresh subprocess with its own session, model, and tools; only the resolved working directory crosses from the parent.
+- **One process per run.** Every run spawns a new process; there is no process pooling.
+- **The ACP wire is the serialization boundary.** Same-process subagent values are not defensively cloned; the protocol is where hostile input is validated.
+
+### Start and ownership flow
+
+A start resolves the child's working directory (the configured `cwd` override, else the parent session's cwd), spawns the command through the subprocess seam, performs the ACP `initialize` and `newSession` handshake, and only then publishes the run. Fulfillment means a remote session is ready and ownership has transferred to the caller. Disposal is idempotent: it closes stdin and waits a configured grace for cooperative quiescence, then escalates through SIGTERM to SIGKILL and awaits whole-tree exit. Cleanup failures remain observable as ordered safe facts and never claim quiescence.
+
+### Stop-reason mapping
+
+The run outcome maps the ACP terminal into the shared stop-reason vocabulary (`completed`, `max-tokens`, `refusal`, `aborted`, or `error`) in [`src/run.ts`](src/run.ts).
+
+### Process boundary
+
+The child spawns through the subprocess seam: credential-shaped ambient variables are scrubbed, then explicit `config.env` values merge after the scrub. Stderr is inherited to the parent's stream, and disposal applies this provider's EOF window before the shared termination escalation.

-ACP（Agent Client Protocol）提供方会在全新的子进程中运行每个 subagent，并作为 Agent Client Protocol 客户端驱动它。这是 spawn 与 fork 的进程外替代方案：子 agent（智能体）拥有自己的运行时、会话、模型配置和工具。
+## 概述
 
-## 启动与所有权
+`dsh-subagent-acp` 在全新的子进程中运行每个被委派的子 agent，并作为 Agent Client Protocol 客户端驱动它：子 agent（智能体）拥有自己的运行时、会话、模型配置和工具，可以是任何兼容 ACP 的 agent，而不只是 Harness。它是进程内 spawn 与 fork 后端的进程外替代方案，只与子 agent 共享父会话的工作目录。每次运行都会 spawn 全新进程、初始化 ACP 会话、发送任务并收集流式最终答案；权限提示由配置自动应答，因此无需人工参与。父级只收到子 agent 的最终答案或安全错误——中间消息与工具流量不会跨越边界。当子 agent 必须与父 harness 完全隔离且能说 ACP 时，选择它。
 
-`start(request)` 先解析子 agent 的工作目录，再依次执行 `spawn` → ACP `initialize` → `newSession`，然后才兑现。因此，兑现表示远程会话已就绪，所有权也已转移给调用方。spawn 失败、初始化失败、新建会话失败或因发布前取消而失败时，通常会在子进程已回收后拒绝；若清理自身也拒绝，有序的安全事实会在普通失败时保留 startup 与 teardown，在取消后只保留 teardown，且不会宣称整棵进程树已经完全停稳。工作目录解析失败则会在尚未 spawn 任何进程时拒绝。非取消拒绝的 Error 消息只公开固定的 provider、stage 与 category 事实；原始失败仍保留在内部 cause 链和 Host 诊断中。
+## 目录
 
-工作目录优先使用已配置的 `cwd` 覆盖值，否则使用执行委派的父会话 cwd，绝不使用服务器进程自身的 cwd，因为同一个服务器进程会服务来自多个工作区的会话。从父级取得的值必须是绝对路径，指向 harness 可以进入的目录（具备搜索权限，这是子进程 cwd 的要求）；解析后的同一路径同时作为子进程 cwd 和 ACP `session/new` 工作区。

+- [进一步探索](#further-exploration)
+- [模型体验](#model-experience)
+- [已知限制与延期工作](#known-limitations-and-deferred-work)
+- [开发备注](#dev-note)
 
-返回的运行 id 在父级命名空间中生成。子服务器的会话 id 只用于 ACP 协议调用，因为 ACP 只保证它在该全新子进程中唯一；若将其用作父级生命周期 id，可能与另一个远程运行或本地 agent 冲突。
+-----
 
-发布后，提供方发送提示词，并把流式 `agent_message_chunk` 文本收集到 `SubagentResult.output`。提示词/传输失败或进程提前退出会以 `stopReason: 'error'` 和安全的 `SubagentResult.diagnostic` 兑现；本地取消以 `aborted` 兑现，且不携带失败细节。部分 assistant 文本继续保留在 `output` 中，与诊断分开。
+<a id="use-this-package"></a>
+## 使用本包
 
-`dispose()` 是幂等的。它会移除信号监听器，在可行时请求 ACP 取消，然后使用该 seam 定义的操作运行本后端自有的拆卸阶梯（`disposeAcpChild`）：先关闭 stdin 并等待 `disposeEofGraceMs` 让子进程协作式完全停稳，再触发句柄的 `terminate()` 升级（SIGTERM、spawn 宽限期、SIGKILL——Windows 直接强制终止），并等待子进程责任方给出整棵进程树的退出证明。每次运行都使用全新进程；尚未实现进程池。
+当组合需要一个说 Agent Client Protocol 的完全隔离进程外子 agent 时，挂载本提供方。常用路径是显式的：挂载 seam、挂载本提供方，并给出一个启动 ACP agent 的命令。
 
-## 能力与上下文
+### 何时选择
 
-ACP 不声明任何启动时能力，因为当前进程无法应用 `request.agentOptions`，也无法强制执行远程子 agent 的深度、工具过滤、persona 或结构化输出运行时。它也报告 `inheritsParentContext: false`：远程会话从全新状态开始，唯一源自父级的输入是上述工作区 cwd；对话上下文不会跨越进程边界。
+当子 agent 必须在独立进程中运行、拥有自己的运行时、模型和工具时选择此后端——例如来自其他项目的 ACP agent——或者你希望委派完全无法触及父 harness 时。当子 agent 必须共享父级组合或遵守父级强制的能力时，请选择进程内后端：本提供方不声明任何可选启动时能力，因此 seam 会拒绝要求 `agentOptions`、结构化输出、深度上限、工具过滤或 persona 的请求，而不是静默省略。

-子进程经由 [`dsh-subprocess`](../../subprocess/subprocess/README.zh.md) seam spawn：共享的凭据清除先移除疑似凭据的环境变量和环境中已有的 `DSH_*` 名称，显式 `config.env` 值在清除之后合并（有意转发的 `DEEPSEEK_API_KEY` 会保留下来，`DSH_PERMISSION_MODE` 这类 `DSH_*` 部署事实也以同样的方式到达子进程——清除只丢弃其陈旧的同名环境值），stderr 会继承到父进程自身的流，dispose 则先应用本插件的 EOF 时间窗，再由子进程责任方执行 SIGTERM→SIGKILL 升级并等待整棵进程树退出。ACP 协议格式（wire format）是真正的序列化边界；同进程 subagent 值不会为防御目的而克隆。

+本节解释后端如何经 ACP 驱动子 agent，以及可观察行为从何而来；完整约定见[使用本包](#use-this-package)。
 
+### 设计理念
+
+- **完全进程隔离。** 每个子 agent 在全新子进程中运行，拥有自己的会话、模型与工具；只有解析后的工作目录从父级跨越。
+- **每次运行一个进程。** 每次运行都 spawn 新进程；没有进程池。
+- **ACP 协议格式（wire format）是序列化边界。** 同进程 subagent 值不会为防御目的克隆；协议才是校验不可信输入的地方。
+
+### 启动与所有权流程
+
+一次启动先解析子 agent 的工作目录（配置的 `cwd` 覆盖值，否则取父会话 cwd），经子进程 seam spawn 命令，完成 ACP `initialize` 与 `newSession` 握手，然后才发布运行。兑现意味着远程会话已就绪、所有权已转移给调用方。dispose（资源释放）是幂等的：先关闭 stdin 并按配置的宽限等待协作式完全停稳，再经 SIGTERM 升级到 SIGKILL，并等待整棵进程树退出。清理失败会作为有序的安全事实保持可观察，且绝不声称已经完全停稳。
+
+### 停止原因映射
+
+运行结果会把 ACP 终态映射进共享的停止原因词汇（`completed`、`max-tokens`、`refusal`、`aborted` 或 `error`），实现见 [`src/run.ts`](src/run.ts)。
+
+### 进程边界
+
+子进程经子进程 seam spawn：先清除疑似凭据的环境变量，再合并显式 `config.env` 值。stderr 继承到父级流，dispose 先应用本提供方的 EOF 窗口，再执行共享的逐级终止。

-This package registers a Profile-named Claude Code subagent provider whose default name is `claude-code`. Each accepted run invokes the official Claude Agent SDK in the delegating Session's workspace, lets the pinned SDK select its installed platform CLI, submits one self-contained text task, and returns either the strict final answer or a separate safe failure diagnostic through the shared [`dsh-subagent`](../subagent/README.md) result contract.
+## Summary
 
-## Start and ownership
+`dsh-subagent-claude-code` registers a Profile-named Claude Code subagent provider (default `claude-code`) that runs a real Claude Code CLI child in the delegating session's workspace through the official Agent SDK. Each accepted run submits one self-contained text task and returns the strict final answer — or a separate safe failure diagnostic — through the shared subagent result contract. The provider ships as an optional Profile Bundle: installing it brings the pinned Agent SDK and one compatible platform CLI payload, while the registered provider stays dormant until a bound tool calls it. Native Claude settings and authentication remain authoritative, and the Profile-selected `permissionMode` decides how the unattended query handles permission checks. Choose it when the child should be a genuine Claude Code product session, fully isolated from the parent harness.
 
-`start(request)` accepts only a non-empty sequence of text blocks and derives the child cwd from the parent Session. It creates one private `AbortController`, calls the official SDK `query()`, and publishes the run only after the SDK's `spawnClaudeCodeProcess` hook has supplied a live CLI handle owned by [`dsh-subprocess`](../../subprocess/subprocess/README.md). A failure or cancellation before publication closes the query, terminates any acquired process tree, waits for it to exit, and rejects `start()`.
+## Table of Contents
 
-The SDK receives the exact concatenated text task. The provider iterates the complete SDK message stream and accepts only a `result` message with `subtype: "success"`, `is_error: false`, and a nonblank `result`, followed by normal iterator completion. Every failure still maps to `error`: turn, budget, and structured-output limits use `limit`; execution failures use `product-error`; error-marked, blank, or missing results use `invalid-result`; an early CLI exit uses `process`; and unclassified failures use `unknown`. The diagnostic also names the current `query-start`, `query-run`, `process`, or `teardown` stage and independently includes an observed exit code and signal. The provider produces neither `max-tokens` nor `refusal`.

+- [Further Exploration](#further-exploration)

+- [Known Limitations and Deferred Work](#known-limitations-and-deferred-work)
+- [Dev Note](#dev-note)
 
-Local cancellation wins the result race and maps to `aborted` without a failure diagnostic. `dispose()` is idempotent: it aborts the run, asks the SDK query to close, invokes the shared process-tree termination escalation, and waits for whole-tree exit. SDK graceful close expresses protocol intent; the subprocess handle remains the authority for process quiescence. Startup and teardown rejections expose the same fixed safe stage and process facts through their Error message, while the original product or Host error remains on the internal cause chain and in the Provider's Host log. Result failure and independent teardown failure remain separate.
+-----
 
-## Native settings and interaction
+<a id="use-this-package"></a>
+## Use this package
 
-The provider deliberately omits the SDK `settingSources` option. The official SDK therefore reads the host's normal user, project, and local Claude settings relative to the parent Session cwd, including native account state and product configuration. The provider neither copies nor filters those files and does not create or modify login state. A configured `model` is passed unchanged to that Provider instance's queries; when it is omitted, the Provider leaves `Options.model` absent and native settings remain authoritative. The Profile-selected `permissionMode` always decides how the unattended query handles permission checks, while Claude Code still owns model interpretation, settings, and sandbox behavior.
+Mount this provider when a delegation should run as a real Claude Code session in the parent's workspace. The common path is explicit: install the Bundle into a Profile, optionally configure the provider row, and expose it to the model through a delegation tool row.
 
-Each query sets `persistSession: false` and disables `AskUserQuestion`. Except in bypass mode, `canUseTool` immediately denies requests that still require human approval. Plan mode also places `ExitPlanMode` in the SDK's `disallowedTools`, so native settings cannot pre-approve a transition back to execution and the model must return the completed plan as its final answer. MCP elicitation is declined, the known refusal fallback dialog is cancelled, and undeclared dialog kinds use the SDK's no-dialog failure behavior. These decisions never wait for a user interface. When both facts contribute to a failed run, `SubagentResult.diagnostic` contains the structured failure line first and the latest safe permission decision second; the shared result boundary limits the complete text to 4096 UTF-8 bytes. Successful and locally cancelled runs expose neither captured fact.
+### Installing the Bundle
 
-## Capabilities and context
-
-The provider advertises no optional start-time capabilities and reports `inheritsParentContext: false`. The shared service rejects `request.agentOptions` for this provider. Claude Code receives the standalone text task and the parent Session cwd, but not the parent conversation, persona, tool filter, depth policy, or structured-output contract. Every run has an independent SDK query, cancellation controller, CLI process, and non-persisted product session.

-| `providerName` | `claude-code` | Non-empty registry name on `ctx.subagents`; each mounted instance needs a unique value. |

-| `env` | `{}` | Explicit SDK/CLI environment layered over the shared credential-scrubbed parent environment. |
-| `permissionMode` | `dontAsk` | Native non-interactive permission policy fixed for every run from this Provider instance. |
-| `disposeGraceMs` | `3000` | Positive finite grace in milliseconds, no greater than [`MAX_TIMER_DELAY_MS`](../../util/timeout/README.md), between the shared process-tree owner's termination tiers; disposal then waits for whole-tree exit. |
-
-| `permissionMode` value | Native behavior |
-|---|---|
-| `dontAsk` | Deny operations that are not already authorized instead of prompting. |
-| `acceptEdits` | Accept file edits; any remaining permission prompt is denied by the unattended callback. |
-| `auto` | Let Claude Code's native classifier allow or deny permission requests. |
-| `plan` | Run in native planning mode, deny execution approval, and return the completed plan as the final answer. |
-| `bypassPermissions` | Explicitly set the SDK's dangerous confirmation and bypass permission checks. |
-
-Production omits `pathToClaudeCodeExecutable`, so Agent SDK 0.3.241 selects the matching native `claude` or `claude.exe` from its own platform package and passes that absolute command through the custom-spawn hook to `dsh-subprocess`. The provider does not inspect `PATH`, implement platform selection, or fall back to a host `claude`. A configured `model` is a direct SDK override owned by the Provider instance; the provider does not discover model names, rewrite aliases, or set a fallback, and omission preserves native model selection. Native settings and authentication remain authoritative for every other product choice. The plugin does not create a product home, log in, or probe an account. Credential-shaped ambient variables are removed before the explicit `env` overlay is applied, so an API key or token intended for the child must be supplied there. Non-credential endpoint variables such as `ANTHROPIC_BASE_URL`, along with ordinary ambient values such as `PATH` and `HOME`, remain inherited unless overridden; `PATH` does not choose the Claude executable.
-
-This package is an optional Profile Bundle. Install it into the target Profile, then restart that Profile; installation brings the pinned Agent SDK and one compatible platform CLI payload into that Profile, while the declared `cordis.patch.yml` layer registers only the dormant `claude-code` Host provider and starts no Claude process. Removing the package withdraws that provider and its private runtime closure on the next Profile start.

The Bundle supplies the dormant default `claude-code` row; the Profile may replace that row's complete config or mount additional rows with distinct `providerName`, `model`, `permissionMode`, and `env` values.

-## Product compatibility and evidence
+The `one-shot` policy keeps omitted or `false` `run_in_background` calls in the foreground, while explicit `true` returns a parent-owned Job id for `job_output` or `job_kill`; the base host and full presets already provide the generic Job registry and controls.
 
-The runtime dependency is pinned to `@anthropic-ai/claude-agent-sdk@0.3.241`, whose eight platform packages carry Claude Code 2.1.241. A normal install selects one payload for the current OS, CPU, and Linux libc. For the current darwin-arm64 payload, `npm pack --dry-run --json` reports 92,295,035 packed bytes and 325,056,216 unpacked bytes; other platforms may differ, and these values are disclosure rather than an installation threshold. The keyless real-product test runs the SDK-selected CLI against a loopback Messages fixture and asserts that the shared subprocess argv begins with that platform package's native executable. It also proves that an omitted model comes from native settings and two named instances send their distinct configured models. Loader composition proves that installing the Bundle registers only dormant Claude Code providers and starts no product process.

-Installing with optional dependencies omitted, using an unsupported platform, or losing the selected payload leaves provider registration dormant but makes the first delegation fail at the SDK startup boundary. The caller receives the safe `query-start` / `unknown` failure fact; the native payload error remains only on the internal cause chain and in the Provider's Host log. The provider neither probes a host CLI nor retries with one.
+A foreground call gives the model the strict final Claude Code answer, or an error with the stop reason and optional safe diagnostic for a failed run. A background call first returns a Job id; the generic job controls later deliver a completion notice and expose the same final answer or failed status through `job_output`. Claude Code reasoning, tool activity, intermediate messages, stderr, and workspace diffs never enter the parent session.
 
-Loader composition proves that the Bundle default, two additional named Claude instances, and the existing Codex package coexist without starting either product.
+### Failure and recovery
 
-The project owner's identity-scoped distribution authorization covers the official SDK and the official CLI/platform payloads declared by each SDK version. [`THIRD_PARTY_NOTICES.md`](../../../THIRD_PARTY_NOTICES.md) discloses the current optional payload closure without classifying its declared terms as permissive; unrelated non-permissive runtime dependencies continue to fail the notices gate.
+An install that omits optional dependencies, uses an unsupported platform, or loses the selected payload leaves the provider dormant and fails the first delegation at the SDK startup boundary with a safe `query-start` / `unknown` failure fact; there is no host-CLI fallback. The original product error stays on the internal cause chain and in the provider's Host log. A cancelled run settles as `aborted`.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the provider drives a real Claude Code CLI and where the observable behavior comes from; the full contract lives in [Use this package](#use-this-package).
+
+### Design concept
+
+- **One fresh query per run.** Every run has an independent SDK query, cancellation controller, CLI process, and non-persisted product session; there is no continuation, resume, or pooling.
+- **Native settings are authoritative.** The provider deliberately omits the SDK `settingSources` option, so Claude Code reads the host's normal user, project, and local settings; an optional `model` and the required `permissionMode` are the only query-level overrides.
+- **Unattended by design.** `AskUserQuestion` is disabled and permission prompts are denied except in bypass mode, so the query never waits for a user interface.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: config schema, provider registration |
+| [`src/run.ts`](src/run.ts) | The SDK query lifecycle, result acceptance, and permission handling |
+| [`src/process.ts`](src/process.ts) | Process-tree termination escalation on disposal |
+| [`cordis.patch.yml`](cordis.patch.yml) | The Profile patch layer that registers the dormant provider |
+
+### Run flow
+
+A start accepts only a non-empty sequence of text blocks and derives the child cwd from the parent session. It creates a private `AbortController`, calls the official SDK `query()` with the exact concatenated task, and publishes the run only after the SDK's custom-spawn hook has supplied a live CLI handle owned by the subprocess seam. The provider iterates the complete message stream and accepts only a `result` message with `subtype: "success"`, `is_error: false`, and a nonblank `result`, followed by normal iterator completion. Every other outcome maps to a fixed-category `error` diagnostic naming the lifecycle stage and observed process outcome — the category set lives in [`src/run.ts`](src/run.ts). Local cancellation wins the result race and maps to `aborted` without a failure diagnostic.

 ## Known Limitations and Deferred Work

+These limits define when this provider is a poor fit or needs special operational care. They are current package constraints, not a general Claude Code comparison or a task backlog.
+
 - **One fresh query and process per run** — there is no continuation, resume, pooling, progress stream, or product-session persistence.
 - **Static instance selection** — Profile rows fix provider names, optional models, and tool bindings; calls cannot choose or change either a provider or model dynamically, and every exposed tool needs a unique `toolName`.
 - **Host settings are intentionally authoritative** — when `model` is omitted, project and user settings choose it; native settings always retain the remaining tools and behavior, and the provider does not provide a filtered or hermetic production mode.
 - **Authentication and account state remain native** — the Bundle supplies the CLI but does not create an account, log in, or rewrite Claude settings; configuration and authentication failures surface with their lifecycle stage and the safe `unknown` fallback rather than a separate public classification.
 - **The SDK platform payload is required at delegation time** — installs that omit optional dependencies, unsupported platforms, and missing or damaged payloads fail at the first query; there is no host-CLI fallback.
 - **No human interaction path** — `AskUserQuestion` is disabled, permission prompts are denied, MCP elicitation is declined, and blocking dialogs fail closed instead of suspending.
-- **Assistant payload is final text only** — a failed run may additionally expose the separate safe diagnostic; reasoning, intermediate messages, tool traffic, usage, stderr, and workspace diffs remain product-local, while generic Job ids, notices, and status come from the shared job runtime.
+- **Assistant payload is final text only** — reasoning, intermediate messages, tool traffic, usage, stderr, and workspace diffs remain product-local.
 - **No optional shared capabilities** — `agentOptions`, output schemas, child personas, tool filtering, and harness depth enforcement are rejected by the shared service for this provider.
 - **No wall-clock timeout or side-effect rollback** — the caller cancels long work, and files or external systems changed before cancellation are not restored.

-本包（package）注册由 Profile 命名、默认名称为 `claude-code` 的 Claude Code subagent 提供方。每次接受运行请求后，它都会在发起委托的会话工作区中调用官方 Claude Agent SDK，让锁定版本的 SDK 选择随包安装的平台 CLI，提交一个自包含的文本任务，并通过共享的 [`dsh-subagent`](../subagent/README.zh.md) 结果约定返回严格的最终答案或独立的安全失败诊断。
+## 概述
 
-## 启动与所有权
+`dsh-subagent-claude-code` 注册由 Profile 命名、默认名称为 `claude-code` 的 Claude Code subagent 提供方，它在发起委派的会话工作区中通过官方 Agent SDK 运行真实的 Claude Code CLI 子 agent（智能体）。每次接受的运行提交一个自包含文本任务，并通过共享的 subagent 结果约定返回严格的最终答案——或独立的安全失败诊断。该提供方作为可选的 Profile Bundle 发布：安装会带入锁定的 Agent SDK 与一个兼容的平台 CLI 载荷，而注册的提供方在绑定工具调用前保持休眠。原生 Claude 设置与身份验证继续是权威来源，Profile 选择的 `permissionMode` 决定这个无人值守 query 如何处理权限检查。当子 agent 应该是与父 harness 完全隔离的真实 Claude Code 产品会话时，选择它。
 
-`start(request)` 只接受非空的文本块序列，并根据父会话确定子级 cwd。它会创建一个私有 `AbortController`，调用官方 SDK 的 `query()`，并仅在 SDK 的 `spawnClaudeCodeProcess` 钩子已经提供由 [`dsh-subprocess`](../../subprocess/subprocess/README.zh.md) 管理的活动 CLI 句柄后发布此次运行。若在发布前发生失败或取消，它会关闭 query、终止所有已取得的进程树并等待其退出，然后拒绝 `start()` 调用。
+## 目录
 
-SDK 接收由文本块原样拼接成的任务。提供方会完整迭代 SDK 消息流，而且只接受满足以下条件的 `result` 消息：其 `subtype: "success"`、`is_error: false` 且 `result` 非空白，之后迭代器还须正常结束。所有失败仍映射为 `error`：轮次、预算与结构化输出限制使用 `limit`；执行失败使用 `product-error`；标记为错误、内容空白或缺失的结果使用 `invalid-result`；CLI 提前退出使用 `process`；未分类失败使用 `unknown`。诊断还会注明当前 `query-start`、`query-run`、`process` 或 `teardown` 阶段，并分别保留已观测到的退出码与信号。该提供方不会产生 `max-tokens` 或 `refusal`。

+- [已知限制与延期工作](#known-limitations-and-deferred-work)
+- [开发备注](#dev-note)
 
-本地取消会在结果竞态中胜出并映射为 `aborted`，且不附带失败诊断。`dispose()`（资源释放）具有幂等性：它会中止此次运行、请求 SDK query 关闭、调用共享的进程树逐级终止机制，并等待整棵进程树退出。SDK 的优雅关闭只表达协议意图；进程是否完全停稳仍以子进程句柄为准。启动与清理拒绝会在 Error 消息中公开同样固定的安全阶段和进程事实，而原始产品或 Host 错误只保留在内部 cause 链与提供方的 Host 日志中。结果失败与独立的清理失败仍彼此分离。
+-----
 
-## 原生设置与交互
+<a id="use-this-package"></a>
+## 使用本包
 
-提供方故意省略 SDK 的 `settingSources` 选项。因此，官方 SDK 会相对于父会话 cwd 读取宿主机常规的用户、项目和本地 Claude 设置，包括原生账户状态与产品配置。提供方既不复制也不过滤这些文件，也不会创建或修改登录状态。若配置了 `model`，提供方会把它原样传给该实例的每次 query；若省略，提供方不会设置 `Options.model`，原生设置继续拥有模型选择权。Profile 选择的 `permissionMode` 始终决定无人值守 query 如何处理权限检查，而模型解释、其他设置与沙箱行为仍由 Claude Code 负责。
+当委派应以父级工作区中的真实 Claude Code 会话运行时，挂载本提供方。常用路径是显式的：把 Bundle 安装进 Profile，可选地配置提供方行，并通过委派工具行把它暴露给模型。
 
-每次 query 都设置 `persistSession: false` 并禁用 `AskUserQuestion`。除 bypass 模式外，`canUseTool` 会立即拒绝仍需人工审批的请求。Plan 模式还会把 `ExitPlanMode` 放入 SDK 的 `disallowedTools`，因此原生 settings 无法预先放行回到执行模式的转换，模型必须把完整计划作为最终答案返回。MCP elicitation 会被拒绝，已知的拒绝回退对话会被取消，未声明的对话类型则使用 SDK 的无对话失败行为。这些决定都不会等待用户界面。当两类事实共同参与一次失败运行时，`SubagentResult.diagnostic` 会先写入结构化失败行，再写入最新的安全权限决定；共享结果边界会把完整文本限制在 4096 个 UTF-8 字节以内。成功运行与本地取消都不会公开已捕获的事实。
+### 安装 Bundle
 
-## 能力与上下文
-
-本提供方不声明任何可选的启动时能力，并报告 `inheritsParentContext: false`。共享服务会拒绝本提供方的 `request.agentOptions`。Claude Code 会接收独立文本任务和父会话 cwd，但不会接收父会话的对话、角色设定、工具筛选器、深度策略或结构化输出约定。每次运行都拥有独立的 SDK query、取消控制器、CLI 进程和不持久化的产品会话。

-| `bypassPermissions` | 显式设置 SDK 的危险确认并跳过权限检查。 |
-
-生产环境会省略 `pathToClaudeCodeExecutable`，因此 Agent SDK 0.3.241 会从自己的平台包中选择匹配的原生 `claude` 或 `claude.exe`，再通过 custom-spawn 钩子把该绝对命令交给 `dsh-subprocess`。提供方不会检查 `PATH`、重复实现平台选择，也不会回退到宿主 `claude`。已配置的 `model` 是由提供方实例拥有的直接 SDK 覆盖；提供方不会发现模型名称、改写别名或设置 fallback，省略该字段会保留原生模型选择。其余产品选择仍以原生设置与身份验证为权威来源。本插件不会创建产品主目录、执行登录或探测账户。具有凭证特征的环境变量会在显式 `env` 覆盖生效前被清除，因此供子进程使用的 API 密钥或 token 必须在该配置中显式提供。除非被覆盖，`ANTHROPIC_BASE_URL` 等非凭证端点变量以及 `PATH` 和 `HOME` 等普通环境变量仍会被继承；`PATH` 不参与选择 Claude 可执行文件。
-
-本包是可选的 Profile Bundle。将它安装进目标 Profile 后重启该 Profile；安装会把锁定的 Agent SDK 与一个兼容的平台 CLI 载荷带入该 Profile，而包所声明的 `cordis.patch.yml` 层只注册休眠的 `claude-code` Host provider，不会启动 Claude 进程。移除该包后，下一次 Profile 启动会撤回这一 provider 及其私有运行时闭包。

-运行时依赖精确锁定为 `@anthropic-ai/claude-agent-sdk@0.3.241`，其八个平台包都携带 Claude Code 2.1.241。普通安装会按当前操作系统、CPU 及 Linux libc 选择一个载荷。对于当前 darwin-arm64 载荷，`npm pack --dry-run --json` 报告压缩包为 92,295,035 字节、解包后为 325,056,216 字节；其他平台可能不同，这些数值只用于披露而不是安装阈值。无密钥真实产品测试会让 SDK 选择 CLI，通过回环 Messages fixture 运行它，并断言共享子进程 argv 的首项就是该平台包的原生可执行文件；它还证明省略 model 时使用原生设置，两个命名实例则发送各自配置的模型。Loader 组合证明安装该 Bundle 只会注册休眠的 Claude Code provider，不会启动产品进程。
+### 你会得到什么
 
-如果安装时省略 optional dependencies、当前平台不受支持，或所选载荷缺失，提供方注册仍保持休眠，但第一次委派会在 SDK 启动边界失败。调用方只会收到安全的 `query-start` / `unknown` 失败事实；原生载荷错误只保留在内部 cause 链和提供方 Host 日志中。提供方既不会探测宿主 CLI，也不会用它重试。
+前台调用会把严格的最终 Claude Code 答案交给模型；运行失败时则返回带停止原因与可选安全诊断的错误。后台调用先返回 Job id；随后通用作业控制面会送达完成通知，并通过 `job_output` 公开同一最终答案或失败状态。Claude Code 的推理、工具活动、中间消息、stderr 与工作区差异绝不会进入父级会话。
 
-Loader 组合证明 Bundle 默认实例、两个额外命名 Claude 实例与现有 Codex 包可以共存，而且不会启动任一产品。
+### 失败与恢复
 
-限定于项目所有者身份的分发授权涵盖官方 SDK 及每个 SDK 版本声明的官方 CLI／平台载荷。[`THIRD_PARTY_NOTICES.md`](../../../THIRD_PARTY_NOTICES.md) 会披露当前可选载荷闭包，但不会认定其中声明的条款属于宽松许可；其他无关的非宽松运行时依赖仍会使第三方声明门禁失败。
+省略 optional dependencies、当前平台不受支持或所选载荷缺失的安装会让提供方保持休眠，并在第一次委派时于 SDK 启动边界以安全的 `query-start` / `unknown` 失败事实失败；不存在宿主 CLI 回退。原始产品错误只保留在内部 cause 链与提供方 Host 日志中。被取消的运行以 `aborted` 结算。

 English | [中文](README.zh.md)
 
-This package registers a Profile-named Codex subagent provider whose default name is `codex`. Each accepted run starts the official package-local Codex wrapper with `app-server --stdio` in the delegating Session's workspace, creates one ephemeral Codex thread, submits one self-contained text task, and returns either the selected final answer or a separate safe failure diagnostic through the shared [`dsh-subagent`](../subagent/README.md) result contract.
+## Summary
 
-## Start and ownership
+`dsh-subagent-codex` registers a Profile-named Codex subagent provider (default `codex`) that runs a real Codex child through the official app-server protocol in the delegating session's workspace. Each accepted run starts the package-local Codex wrapper with `app-server --stdio`, creates one ephemeral Codex thread, submits one self-contained text task, and returns the selected final answer — or a separate safe failure diagnostic — through the shared subagent result contract. The provider ships as an optional Profile Bundle: installing it brings the official wrapper and one compatible native platform payload, while the registered provider stays dormant until a bound tool calls it. Native Codex configuration and authentication remain authoritative, and the Profile-selected `permissionMode` maps into the thread's approval, reviewer, and sandbox fields. Choose it when the child should be a genuine Codex session, fully isolated from the parent harness.
 
-`start(request)` accepts only a non-empty sequence of text blocks and derives the child cwd from the parent Session. It then spawns the fixed command through [`dsh-subprocess`](../../subprocess/subprocess/README.md), performs `initialize` → `initialized`, maps the Profile-selected mode and optional model into official `thread/start` fields beside `{ cwd, ephemeral: true }`, and publishes the run only after Codex returns a valid ephemeral thread. A failure or cancellation before publication closes the wire, terminates the managed process tree, waits for it to exit, and rejects `start()`. Non-cancellation rejections expose only the fixed `initialize` or `thread-start` stage plus an already observed process outcome; raw product and Host errors remain on internal cause chains.
+## Table of Contents
 
-The published `run.result` starts exactly one turn. It accepts only notifications for that run's thread and turn, then waits for the authoritative `turn/completed` terminal notification. The latest `agentMessage` with `phase: "final_answer"` wins; when Codex emits no explicit final phase, the latest message with `phase: null` is the compatibility fallback. Commentary never replaces either answer, and a successful turn with no nonblank answer settles as an error.

-For command and file approvals, the unattended provider selects a non-approval decision offered by the request, preferring `cancel`; the stable 0.149.1 request shape without an offered-decision list falls back to `decline`. It answers permission requests with an empty turn-scoped permission set, answers user-input requests with no answers, and declines MCP elicitation. A request with no legal unattended response, or any unknown server request, fails the run. The wire records only the effective mode, request category, decision, and fixed safe reason. It also recognizes declined command/file items and structured `sandboxError` terminals. Product stderr is forwarded unchanged to the Host but is never classified or copied into the diagnostic.
+-----
 
-Local cancellation wins the result race and maps to `aborted`. Failed turns use the coarse categories `limit`, `access-policy`, `service`, `transport`, `product-error`, `invalid-result`, or `unknown`; an early app-server exit uses `process`. Applicable connection and stream failures retain a numeric `httpStatusCode`. The diagnostic also names `turn-start`, `turn`, or `process` and independently includes available exit code and signal without copying raw fields. `contextWindowExceeded` remains `max-tokens`; every other remote interruption or failure remains `error`, and the provider produces no `refusal`. A contributing structured permission decision follows the failure line. Successful and locally cancelled runs omit both facts.
+<a id="use-this-package"></a>
+## Use this package
 
-`dispose()` is idempotent: it requests a best-effort `turn/interrupt` with both current ids when they are known, closes the JSON-RPC wire, ends stdin, invokes the shared process-tree termination escalation, waits for whole-tree exit, and detaches the stderr observer. Independent cleanup rejection uses the fixed `teardown` stage and any available process outcome. When startup and rollback both fail, the top-level aggregate message preserves both safe stage lines while the raw failures remain internal.
+Mount this provider when a delegation should run as a real Codex session in the parent's workspace. The common path is explicit: install the Bundle into a Profile, optionally configure the provider row, and expose it to the model through a delegation tool row.
 
-## Capabilities and context
+### Installing the Bundle
 
-The provider advertises no optional start-time capabilities and reports `inheritsParentContext: false`. The shared service rejects `request.agentOptions` for this provider. Codex receives the standalone text task and the parent Session cwd, but not the parent conversation, persona, tool filter, depth policy, or structured-output contract. The ephemeral Codex thread id and turn id stay private to this run and are never persisted in the parent Session.

-## Configuration
-
-| Key | Default | Meaning |
-|---|---|---|
-| `providerName` | `codex` | Non-empty registry name on `ctx.subagents`; each mounted instance needs a unique value. |
-| `model` | native Codex settings | Optional non-empty native model name fixed for every thread from this Provider instance; omission sends no app-server override. |
-| `env` | `{}` | Explicit child environment layered over the subprocess seam's credential-scrubbed parent environment. |
-| `permissionMode` | `never` | Native non-interactive approval and sandbox mode fixed for every thread from this Provider instance. |
-| `disposeGraceMs` | `3000` | Positive finite grace in milliseconds, no greater than [`MAX_TIMER_DELAY_MS`](../../util/timeout/README.md), between the shared process-tree owner's termination tiers; disposal then waits for whole-tree exit. |
-
-| `permissionMode` value | `thread/start` fields | Native behavior |
-|---|---|---|
-| `never` | `approvalPolicy: never`; sandbox omitted | Never ask for approval; execution failures return to the model under the native sandbox. |
-| `approve-for-me` | `approvalPolicy: on-request`, `approvalsReviewer: auto_review`, `sandbox: workspace-write` | Route permission requests through Codex automatic review without a human. |
-| `dangerously-bypass-approvals-and-sandbox` | `approvalPolicy: never`, `sandbox: danger-full-access` | Skip approval and sandbox enforcement; this value must be selected explicitly. |
-
-Production resolves the `codex` bin declared by its pinned `@openai/codex@0.149.1` dependency and launches that JavaScript wrapper with the current Node executable. The wrapper selects the matching native platform payload; the provider neither inspects nor falls back to a host `codex` on `PATH`. Native Codex configuration and authentication remain authoritative through the parent cwd, `HOME`, and `CODEX_HOME`. A configured `model` is passed unchanged on each ephemeral `thread/start`; omission leaves the field absent, and the Provider does not discover models, rewrite aliases, select `modelProvider` or `serviceTier`, or set a fallback. The selected permission mode remains the only other thread-level override. The plugin does not create `CODEX_HOME`, log in, or probe an account. Credential-shaped ambient variables are removed by the subprocess seam before the explicit `env` overlay is applied.
-
-This package is an optional Profile Bundle. Install it into the target Profile, then restart that Profile; installation brings the official wrapper and one compatible native platform payload into that Profile, while the declared `cordis.patch.yml` layer registers only the dormant `codex` Host provider and starts no Codex process. Removing the package withdraws that provider and its private runtime closure on the next Profile start.

-Installation controls Host availability, not model permission. The Bundle supplies the dormant default `codex` row; the Profile may replace that row's complete config or mount additional rows with distinct `providerName`, `model`, `permissionMode`, and `env` values. Loading an instance starts no Codex process until a bound tool calls it. Each `dsh-tool-subagent` row names one provider and needs its own `toolName`, so the model sees static tools rather than a dynamic provider or model selector. Full Agent Presets carry a matching default product tool row with `disabled: true`; copy a preset and remove that field to expose `subagent_codex` only to agents composed from the copy. Its `one-shot` policy keeps omitted or `false` `run_in_background` calls in the foreground, while explicit `true` returns a parent-owned Job id for `job_output` or `job_kill`. The base host and full presets already provide the generic Job registry and controls.

-## Product compatibility and evidence
+The `one-shot` policy keeps omitted or `false` `run_in_background` calls in the foreground, while explicit `true` returns a parent-owned Job id for `job_output` or `job_kill`; the base host and full presets already provide the generic Job registry and controls.
 
-The production wire intentionally implements only the app-server methods required by this one-shot contract. The runtime dependency and all six optional-dependency aliases are pinned to `@openai/codex@0.149.1` / `codex-cli 0.149.1`. A normal install selects one payload for the current OS and CPU. For the current darwin-arm64 payload, `npm pack --dry-run --json @openai/codex@0.149.1-darwin-arm64` reports 114,152,335 packed bytes and 282,491,555 unpacked bytes. That package contains native `codex`, `codex-code-mode-host`, `rg`, and `zsh` resources; other platforms may differ, and these values are disclosure rather than an installation threshold.
+### What you get
 
-Generated schema evidence pins the optional `ThreadStartParams.model` field, while package tests cover representative error groups, applicable HTTP status, six lifecycle stages, process outcomes, stop-reason mapping, unknown fallback, sanitization, structured permission ordering, cancellation, concurrency, and cleanup aggregation. The keyless real-product test drives the package wrapper against a loopback Responses fixture and observes the package-local argv, omitted-model inheritance, two explicit instance models, exact Bearer key, original task, byte-exact final answer, thread-level `never` overriding ambient `on-request`, automatic-review startup, unattended rejection without file side effects, a real service failure, explicit dangerous-bypass writing in suite-owned temporary storage, process/protocol failure with safe exit facts, and wrapper/native quiescence.
+A foreground call gives the model the selected final Codex answer, or an error with the stop reason and optional safe diagnostic for a failed run. A background call first returns a Job id; the generic job controls later deliver a completion notice and expose the same final answer or failed status through `job_output`. Codex commentary, reasoning, tool activity, raw stderr, and workspace diffs never enter the parent session.
 
-Installing with optional dependencies omitted, using an unsupported platform, or losing the selected payload makes the first delegation fail at `initialize` with the safe `unknown` category and any observed process outcome. Raw wrapper text remains on Host stderr; the provider neither probes a host CLI nor retries with one. An isolated wrapper fixture separately proves the native payload failure and absence of host fallback.
+### Failure and recovery
 
+An install that omits optional dependencies, uses an unsupported platform, or loses the selected payload leaves the provider dormant and fails the first delegation at `initialize` with a safe `unknown` category and any observed process outcome; there is no host-CLI fallback. Raw wrapper text stays on Host stderr. A cancelled run settles as `aborted`.

+- **One fresh process, thread, and turn per run.** Every run spawns a fresh app-server, creates one ephemeral thread, and executes exactly one turn; there is no continuation, resume, or pooling.
+- **Native configuration is authoritative.** Codex configuration and authentication stay native through the parent cwd, `HOME`, and `CODEX_HOME`; the provider overrides only the optional model and the thread's approval, reviewer, and sandbox fields.

The published result starts exactly one turn, accepts only notifications for that run's thread and turn, and waits for the authoritative `turn/completed` terminal. The latest `agentMessage` with `phase: "final_answer"` wins; when Codex emits no explicit final phase, the latest message with `phase: null` is the compatibility fallback. A successful turn with no nonblank answer settles as an error.

-`start(request)` 只接受非空的文本块序列，并根据父会话确定子级 cwd。随后，它通过 [`dsh-subprocess`](../../subprocess/subprocess/README.zh.md) spawn 固定命令，依次执行 `initialize` → `initialized`，把 Profile 选择的模式与可选模型映射为官方 `thread/start` 字段并与 `{ cwd, ephemeral: true }` 一起发送，且仅在 Codex 返回有效的临时线程后才发布此次运行。若在发布前发生失败或取消，它会关闭通信链路、终止受管进程树并等待其退出，然后拒绝 `start()` 调用。非取消拒绝只公开固定的 `initialize` 或 `thread-start` 阶段及已经观测到的进程结果；原始产品与 Host 错误只保留在内部 cause 链中。
+## 目录
 
-已发布的 `run.result` 恰好启动一个轮次。它只接受与此次运行的线程和轮次匹配的通知，随后等待权威的终止通知 `turn/completed`。以最后一条 `phase: "final_answer"` 的 `agentMessage` 为准；若 Codex 没有发出明确的最终阶段，则以最后一条 `phase: null` 的消息作为兼容性回退。过程说明绝不会取代上述任一答案；成功完成的轮次若没有非空白答案，结果也会判为错误。

-对于命令与文件审批，无人值守的提供方会从请求给出的决策选项中选择一项不予批准的决策，并优先选择 `cancel`；稳定的 0.149.1 请求形态没有决策选项列表，因此回退到 `decline`。它对权限请求返回作用域限于当前轮次的空权限集，不向用户输入请求提供任何答案，并拒绝 MCP elicitation。若请求在无人值守模式下没有合法响应，或是未知服务器请求，此次运行就会失败。wire 只记录有效模式、请求类别、决定与固定的安全原因，也会识别被拒绝的命令／文件 item 和结构化 `sandboxError` 终态。产品 stderr 会原样转发给 Host，但绝不会被分类或复制进诊断。
+-----
 
-本地取消会在结果竞态中胜出并映射为 `aborted`。失败轮次使用粗粒度类别 `limit`、`access-policy`、`service`、`transport`、`product-error`、`invalid-result` 或 `unknown`；app-server 提前退出使用 `process`。适用的连接与 stream 失败会保留数值 `httpStatusCode`。诊断还会注明 `turn-start`、`turn` 或 `process`，分别包含可用的退出码与信号，且不复制原始字段。`contextWindowExceeded` 仍映射为 `max-tokens`；其他任何远端中断或失败仍映射为 `error`，且该提供方不会产生 `refusal`。参与失败的结构化权限决定会跟在失败行之后。成功与本地取消都不附带这两类事实。

+## 使用本包
 
-`dispose()`（资源释放）具有幂等性：如果当前的两个标识符均已知，它会尽力请求 `turn/interrupt`，关闭 JSON-RPC 通信链路，结束标准输入，调用共享的进程树逐级终止机制，等待整棵进程树退出，并移除 stderr observer。独立清理拒绝使用固定的 `teardown` 阶段与可用进程结果。当启动与回滚同时失败时，顶层聚合消息会保留两条安全阶段说明，而原始失败仍只在内部可见。

-## 能力与上下文
+### 安装 Bundle
 
-本提供方不声明任何可选的启动时能力，并报告 `inheritsParentContext: false`。共享服务会拒绝本提供方的 `request.agentOptions`。Codex 会接收独立文本任务和父会话 cwd，但不会接收父会话的对话、角色设定、工具筛选器、深度策略或结构化输出约定。临时 Codex 线程 ID 与轮次 ID 仅在此次运行内部可见，绝不会持久化到父会话。

-生产环境的协议层有意只实现这一单次执行约定所需的 app-server 方法。运行时依赖与六个 optional-dependency alias 均锁定到 `@openai/codex@0.149.1` / `codex-cli 0.149.1`。普通安装会按当前操作系统与 CPU 选择一个载荷。对于当前 darwin-arm64 载荷，`npm pack --dry-run --json @openai/codex@0.149.1-darwin-arm64` 报告压缩包为 114,152,335 字节、解包后为 282,491,555 字节。该包包含原生 `codex`、`codex-code-mode-host`、`rg` 与 `zsh` 资源；其他平台可能不同，这些数值只用于披露而不是安装阈值。
+### 你会得到什么

+前台调用会把选定的最终 Codex 答案交给模型；运行失败时则返回带停止原因与可选安全诊断的错误。后台调用先返回 Job id；随后通用作业控制面会送达完成通知，并通过 `job_output` 公开同一最终答案或失败状态。Codex 的过程说明、推理、工具活动、原始 stderr 与工作区差异绝不会进入父级会话。
 
-如果安装时省略 optional dependencies、当前平台不受支持，或所选载荷缺失，第一次委派会在 `initialize` 阶段以安全 `unknown` 类别和已观测到的进程结果失败。原始 wrapper 文本只保留在 Host stderr；提供方既不会探测宿主 CLI，也不会用它重试。独立 wrapper fixture 会另行证明原生载荷失败与不存在宿主回退。
+### 失败与恢复

+本节解释提供方如何驱动真实 Codex app-server，以及可观察行为从何而来；完整约定见[使用本包](#use-this-package)。
+
+### 设计理念
+
+- **每次运行一个全新进程、线程与轮次。** 每次运行都会 spawn 全新 app-server、创建一个临时线程并恰好执行一个轮次；没有续接、恢复或池化。
+- **原生配置是权威。** Codex 配置与身份验证经父级 cwd、`HOME` 与 `CODEX_HOME` 保持原生；提供方只覆盖可选模型以及线程的 approval、reviewer 与 sandbox 字段。
+- **刻意无人值守。** 审批、用户输入与 MCP 请求都会在无人参与的情况下被应答或拒绝；未知服务器请求会使运行失败。

 ### 父级调度与结果（间接）
 
-#### 模型看到的内容
+#### 模型看到什么
 
 通过 `dsh-tool-subagent`，前台调用会让父级模型看到选定的 Codex 最终答案；若结果未完成，错误中会包含终止原因和可选的安全诊断。该诊断可以区分粗粒度行动类别、协议阶段、适用的数值 HTTP status 和已观测的进程结果，而不复制产品正文或 stderr。后台调用会先返回 Job id；随后通用作业控制面会送达完成通知，通过 `job_output` 公开同一最终答案或失败状态 detail，并允许 `job_kill` 请求取消。Codex 的过程说明、推理（reasoning）、工具活动、原始 stderr、工作区差异、用量信息、产品标识符、命令、路径和协议载荷均不会复制到父会话。
 
-#### 对 token 的影响
+#### Token 影响
 
 前台输入会增加工具结果中保留的最终答案或错误内容。后台输入还会包含启动确认、完成通知，以及 `job_output`、`job_kill` 或后续状态结果；子任务 token 仍不会进入父级上下文。本提供方自身不添加父级工具 schema。
 
-#### 对 KV Cache 的影响
+#### KV Cache 影响
 
 仅追加：前台会在可复用的父请求前缀后增加一个结果，后台则会继续追加 Job 启动确认、通知以及后续控制或收集结果。后台调度可能增加一个由通知唤醒的轮次，但这些消息都不会改写更早的前缀。

 # @deepseek-ai/dsh-subagent-dsh-sdk
 
 English | [中文](README.zh.md)
 
-The SDK provider runs each subagent as a complete DeepSeek Harness runtime in a fresh subprocess, driven over stdio JSON-RPC through the [TypeScript SDK client](../../sdk/client/README.md). It is the second out-of-process backend beside [`subagent-acp`](../subagent-acp/README.md), differing in the wire and child application: the ACP backend drives any Agent Client Protocol agent; this backend launches the same-version `dsh --profile sdk` application, so the child has its own profile-and-patch composition, session persistence, model route, and tools.
+## Summary
 
-## Start and ownership
+`dsh-subagent-dsh-sdk` runs each delegated child as a complete DeepSeek Harness runtime in a fresh subprocess, driven over stdio JSON-RPC through the TypeScript SDK client. It is the second out-of-process backend beside the ACP provider, differing in the wire and the child contract: the child is a full peer harness with its own `cordis.yml`-decided composition, session persistence, model route, and tools. Each run spawns the child runtime (the resolved `@deepseek-ai/dsh` CLI under Node, or the configured `dshBin`), completes an `initialize` handshake with the configured provider and model route, submits the task, and reads the answer from the child's session events. The parent receives only the child's final assistant text or a safe error — no intermediate messages or tool traffic crosses the boundary. Choose it when the child should be a genuine Harness runtime, fully isolated from the parent harness.
 
-`start(request)` rejects an already-aborted request, then resolves the child's working directory and one process-wide SDK route before spawning. Each declared `request.agentOptions` field (`provider`, `model`, `reasoningEffort`, or `maxTokens`) overrides the matching provider-instance default; omission preserves the configured provider/model and optional cap, while reasoning effort remains omitted unless the request supplies it. The provider then spawns through `DeepSeekHarness` and completes the child runtime's `initialize` handshake, including exact-model and effort validation, before it fulfills. Fulfillment therefore means the child runtime is ready and ownership has transferred to the caller. A route, spawn, handshake, or pre-publication cancellation failure ordinarily rejects after the subprocess is reaped; when cleanup itself rejects, ordered safe facts preserve initialize plus shutdown for an ordinary failure, or shutdown alone after cancellation, without claiming complete process quiescence. A working-directory resolution failure rejects before anything is spawned. Non-cancellation rejections expose only fixed provider, stage, and category facts in their Error message; the original SDK failure remains on the internal cause chain and in Host diagnostics.
+## Table of Contents
 
-The working directory resolves exactly like the ACP backend, through the seam's shared out-of-process helpers ([`dsh-subagent`](../subagent/README.md)): the configured `cwd` override when set (validated once at load), else the delegating parent session's cwd — never the server process's own cwd. The resolved path becomes the child process cwd and the workspace cwd of its SDK session. `dshHome` is separately required as an absolute path so a nested runtime cannot accidentally share its parent's profiles, plugin installation, or session storage.

-The returned run id is minted in the parent namespace; the child runtime's session id exists only inside the child process. After publication the provider owns one SDK activity and reads the child's answer from its session events: the last complete non-empty `assistant/message` (an empty-content message that records usage is skipped), or the accumulated `text-delta` stream when no such message exists. Partial output remains available after cancellation or an error, separate from any `SubagentResult.diagnostic`.
+-----
 
-`dispose()` is idempotent: it settles the result locally as `aborted` (there is no wire-level prompt cancel), then closes the runtime — a bounded protocol `shutdown` request followed by the shared stdin-EOF → SIGTERM → SIGKILL ladder to actual exit.
+<a id="use-this-package"></a>
+## Use this package
 
-## Stop-reason mapping
+Mount this provider when a delegation should run as a complete Harness runtime in its own process. The common path is explicit: mount the seam, mount this provider, and give it a command that starts an SDK runtime with its own `cordis.yml`.
 
-The SDK client returns an owned child activity rather than a prompt result. The provider reads the last durable `turn/end` inside that activity and preserves the existing seam stop reason while adding detail only where it changes the next action.
+### When to choose it
 
-| Child turn reason | Harness | Additional diagnostic |
+Choose this backend when the child must be a full harness peer — its own composition, session persistence, model route, and tools — rather than an agent that shares the parent's process. Choose an in-process backend when the child must share the parent's composition or honor parent-enforced non-route capabilities: this provider accepts agent route options but rejects structured output, depth caps, tool filters, and personas rather than silently omitting them.
+
+The provider advertises `agentOptions: true`, with `outputSchema`/`depthLimit`/`toolFilter`/`persona` false, and `inheritsParentContext: false`. Its immutable `agentRouteDefaults` publish the configured provider/model baseline to `dsh-tool-subagent` before model overrides and exact-route preflight; `start()` independently applies the same configuration defaults for direct callers and `maxTokens`. Agent route values cross the SDK wire as an explicit whitelist; the child remains a fresh runtime in another process, and the only value derived from the parent agent itself is the workspace cwd. `dsh-tool-subagent` deployments over this provider set `maxDepth: 'provider-managed'` — the child harness owns its own recursion budget.

-## Failure diagnostics
-
-The first line follows the shared fixed form:
-
-```text
-Subagent failure (provider: DSH SDK; stage: <stage>; category: <category>)
-```
-
-The shared result boundary limits the complete text to 4096 UTF-8 bytes. The provider derives `initialize`, `session-run`, or `shutdown` at the operation that owns the failure. During initialize or session run, `SdkProtocolError` and JSON-RPC error responses map to `protocol`, `TransportClosedError` maps to `transport`, and other exceptions use `unknown`. A shutdown rejection uses `unknown`: the SDK client keeps protocol-shutdown failures in Host diagnostics, so only runtime-process disposal can reject `close()`. Classification never reads an error message, so the stderr tail carried by `TransportClosedError`, paths, task content, environment values, credentials, and protocol payloads remain Host-only. Request timeout classification is deferred until this provider configures or propagates a request timeout; the current SDK launch waits indefinitely for ordinary requests.
-
-Successful results and local cancellation omit diagnostics. Startup and shutdown rejections use the same safe line in their Error message while retaining the original cause internally. A diagnostic-bearing child `aborted` result remains `aborted`; the one-shot Job adapter classifies it as failed, while diagnostic-free local cancellation remains killed.
-
-## Capabilities and context
-
-The provider advertises `agentOptions: true`, with `outputSchema`/`depthLimit`/`toolFilter`/`persona` false, and `inheritsParentContext: false`. Its immutable `agentRouteDefaults` publish the configured provider/model baseline to `dsh-tool-subagent` before model overrides and exact-route preflight; `start()` independently applies the same Config defaults for direct callers and maxTokens. Agent route values cross the SDK wire as an explicit whitelist; the child remains a fresh runtime in another process, and the only value derived from the parent Agent itself is the workspace cwd. `dsh-tool-subagent` deployments over this provider set `maxDepth: 'provider-managed'` — the child harness owns its own recursion budget.
-
-## Configuration
-
-| Key | Default | Meaning |
-|---|---|---|
-| `providerName` | `dsh-sdk` | Registry name on `ctx.subagents`. |
-| `dshBin` | same-version SDK dependency | Explicit dsh CLI module override. A relative path resolves at plugin load and must name an existing file. Ordinary deployments omit it. |
-| `profile` | `sdk` | Named dsh profile launched for each child. The profile must include the SDK app. |
-| `patches` | `[]` | Ordered per-launch profile patch files. Relative paths resolve at plugin load, and every path must name an existing file. |
-| `dshHome` | required | Absolute isolated dsh home for the nested runtime's profiles, installed plugins, and session data. |
-| `cwd` | parent session cwd | Working-directory override; same validation as [`subagent-acp`](../subagent-acp/README.md). |
-| `provider` | `deepseek-official` | Provider route sent in the child's `initialize`. |
-| `model` | `deepseek-v4-flash` | Model sent in the child's `initialize`. |
-| `maxTokens` | adapter/provider route default | Per-request output-token cap sent in the child's `initialize`; it applies to the child root agent and its in-process descendants. |
-| `env` | `{}` | Explicit child environment layered over a credential-scrubbed parent environment, such as the child's own `DEEPSEEK_API_KEY`. |
-| `shutdownTimeoutMs` | `1000` | Bound on the protocol `shutdown` exchange during dispose. |
-| `disposeEofGraceMs` | `6000` | Grace after stdin EOF before platform termination. |
-| `disposeGraceMs` | `3000` | Exit-confirmation grace after termination; POSIX also waits this long after SIGTERM before SIGKILL. |

-## Process boundary
+### What you get
 
-The child environment is the [`dsh-subprocess`](../../subprocess/README.md) seam's `scrubbedParentEnv()` base — ambient credential-shaped and `DSH_*` names dropped — with explicit `config.env` values merged after the scrub. The child is spawned by the SDK client rather than through `ctx.subprocess` (the subprocess README's documented exception for SDK-managed transports), which is why this backend applies the scrub itself. The JSON-RPC wire is the real serialization boundary.
+A successful run returns the child's final assistant text (or accumulated partial text after cancellation) as result output. The child's model route, tools, and session come from the child runtime itself — the parent supplies the task, working directory, and `initialize` route. The child's last durable `turn/end` maps into the seam vocabulary: `completed` and `max-tokens` pass through, `blocked` becomes `refusal`, and an unexpected or missing terminal becomes `error`. An `aborted` result stays aborted; only a child-side `disposed` cause adds a `child-disposed` diagnostic.
 
-The package has no default export. Cordis loader unwrapping would otherwise hide the named `inject` metadata; see [postmortem 0001](../../../docs/postmortem/0001-acp-default-export-drops-inject.md).
+### Failure and recovery
 
+An already-aborted request fails before path resolution or spawn. A route, spawn, handshake, or pre-publication cancellation failure ordinarily rejects only after the subprocess is reaped. If initialization and cleanup both fail, the ordered safe facts preserve both failures without claiming quiescence. A child runtime that fails after publication settles through the run rather than rejecting it; partial output stays separate from the safe diagnostic. Diagnostics expose only the provider plus `initialize`, `session-run`, or `shutdown` stage and a fixed category. They never copy SDK messages, stderr, paths, task content, environment values, credentials, or protocol payloads.

+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the backend drives a child Harness runtime and where the observable behavior comes from; the full contract lives in [Use this package](#use-this-package).
+
+### Design concept
+
+- **Full harness peer.** Each child is a complete Harness runtime in its own process — own composition, session, model route, and tools; only the resolved working directory and the `initialize` route cross from the parent.
+- **One runtime per run.** Every run spawns a fresh runtime process; there is no pooling.
+- **The JSON-RPC wire is the serialization boundary.** Same-process subagent values are not defensively cloned; the protocol is where hostile input is validated.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: config schema, provider registration |
+| [`src/run.ts`](src/run.ts) | The SDK run lifecycle, answer extraction, and stop-reason mapping |
+
+### Run flow
+
+A start resolves the child's working directory and one process-wide SDK route before spawning. Each declared `request.agentOptions` field (`provider`, `model`, `reasoningEffort`, or `maxTokens`) overrides the matching provider-instance default; omission preserves the configured provider/model and optional cap, while reasoning effort remains absent unless the request supplies it. The provider spawns the runtime through the SDK client and completes the `initialize` handshake, including exact-model and effort validation, before it fulfills. A route, spawn, handshake, or pre-publication cancellation failure rejects only after the subprocess is reaped; a working-directory resolution failure rejects before spawning. After publication the provider owns one SDK activity and reads the child's answer from its session events: the last complete non-empty `assistant/message` (an empty-content message that records usage is skipped), or the accumulated `text-delta` stream when no such message exists. Disposal is idempotent: it settles the result locally as `aborted`, sends a bounded protocol `shutdown` request, then escalates through stdin EOF → SIGTERM → SIGKILL to actual exit.
+
+### Stop-reason mapping
+
+The child's last `turn/end` reason maps into the shared stop-reason vocabulary in [`src/run.ts`](src/run.ts).
+
+### Process boundary
+
+The child environment is the subprocess seam's credential-scrubbed parent environment with explicit `config.env` values merged after the scrub. The child is spawned by the SDK client rather than through `ctx.subprocess` — the documented exception for SDK-managed transports — which is why this backend applies the scrub itself.

 [English](README.md) | 中文
 
-SDK 提供方会在全新的子进程中把每个 subagent 作为完整的 DeepSeek Harness 运行时运行，并经由 [TypeScript SDK 客户端](../../sdk/client/README.zh.md) 通过 stdio JSON-RPC 驱动。它是 [`subagent-acp`](../subagent-acp/README.zh.md) 之外的第二个进程外后端，差异在协议格式（wire format）和子应用：ACP（Agent Client Protocol）后端能驱动任何 Agent Client Protocol agent（智能体）；本后端启动同版本的 `dsh --profile sdk` 应用，因此子进程拥有自己的 profile 与 patch 组合、会话持久化、模型路由和工具。
+## 概述
 
-## 启动与所有权
+`dsh-subagent-dsh-sdk` 在全新的子进程中把每个被委派的子 agent（智能体）作为完整的 DeepSeek Harness 运行时运行，并经由 TypeScript SDK 客户端通过 stdio JSON-RPC 驱动。它是 ACP 提供方之外的第二个进程外后端，差异在协议格式（wire format）与子进程约定：子进程是完整的对等 harness，拥有由 `cordis.yml` 决定的组合、会话持久化、模型路由与工具。每次运行都会 spawn 子运行时（Node 下解析出的 `@deepseek-ai/dsh` CLI，或配置的 `dshBin`），以配置的提供方与模型路由完成 `initialize` 握手、提交任务，并从子进程的会话事件中读取答案。父级只收到子进程最终的 assistant 文本或安全错误——中间消息与工具流量不会跨越边界。当子进程应该是与父 harness 完全隔离的真实 Harness 运行时时，选择它。
 
-`start(request)` 会先拒绝已经取消的请求，再在 spawn 前解析子进程工作目录与一条进程级 SDK 路由。`request.agentOptions` 中每个已声明字段（`provider`、`model`、`reasoningEffort` 或 `maxTokens`）都会覆盖对应的提供方实例默认值；省略时保留已配置的提供方／模型与可选上限，而推理强度只有在请求提供时才会出现。随后，提供方通过 `DeepSeekHarness` spawn 运行时，并在履行前完成子运行时的 `initialize` 握手，其中包括确切模型与推理强度校验。因此，履行意味着子运行时已就绪、所有权已移交给调用方。路由、spawn、握手或发布前取消失败通常会在子进程被回收后拒绝；若清理自身也拒绝，有序的安全事实会在普通失败时保留 initialize 与 shutdown，在取消后只保留 shutdown，且不会宣称进程已经完全停稳。工作目录解析失败则会在尚未 spawn 任何内容时拒绝。非取消拒绝的 Error 消息只公开固定的 provider、stage 与 category 事实；原始 SDK 失败仍保留在内部 cause 链和 Host 诊断中。
+## 目录
 
-工作目录的解析与 ACP 后端完全一致，并使用 seam 共享的进程外辅助工具（[`dsh-subagent`](../subagent/README.zh.md)）：设置了 `cwd` 覆盖值时使用该值（加载时校验一次），否则使用发起委派的父会话 cwd，绝不使用服务器进程自身的 cwd。解析出的路径同时成为子进程 cwd 和其 SDK 会话的工作区 cwd。`dshHome` 必须另外指定为绝对路径，使嵌套运行时不会意外共享父运行时的 profile、插件安装或会话存储。

+- [进一步探索](#further-exploration)
+- [模型体验](#model-experience)
+- [已知限制与延期工作](#known-limitations-and-deferred-work)
+- [开发备注](#dev-note)
 
-返回的 run id 在父级命名空间中生成；子运行时的会话 id 只存在于子进程内部。发布后，提供方拥有一段 SDK 活动，并从子会话事件中读取答案：最后一条完整且非空的 `assistant/message`（记录 usage 的空内容消息会被跳过）；若没有这类消息，则取累积的 `text-delta` 流。取消或发生错误后，部分输出仍然可用，并与 `SubagentResult.diagnostic` 分开。
+-----
 
-`dispose()`（资源释放）是幂等的：先在本地把结果确定为 `aborted`（协议层面没有提示词取消机制），再关闭运行时，即先发出一次有界的协议 `shutdown` 请求，随后通过共享的 stdin-EOF → SIGTERM → SIGKILL 阶梯使进程实际退出。
+<a id="use-this-package"></a>
+## 使用本包
 
-## 停止原因映射
+当委派应以完整 Harness 运行时在独立进程中运行时，挂载本提供方。常用路径是显式的：挂载 seam、挂载本提供方，并给出一个启动带有自身 `cordis.yml` 的 SDK 运行时的命令。
 
-SDK 客户端返回自有子活动，而不是提示词结果。提供方读取该活动内最后一个已持久化的 `turn/end`，保留既有 seam 结束原因，并只在会改变下一步动作时附加细节。
+### 何时选择
 
-| 子轮次原因 | Harness | 附加诊断 |
+当子进程必须是完整的 harness 对等体——拥有自己的组合、会话持久化、模型路由与工具——而不是共享父进程的 agent 时，选择此后端。当子进程必须共享父级组合或遵守父级强制的非路由能力时，请选择进程内后端：本提供方接受 agent 路由选项，但会拒绝结构化输出、深度上限、工具过滤或 persona，而不是静默省略。
+
+提供方声明 `agentOptions: true`，同时保持 `outputSchema`/`depthLimit`/`toolFilter`/`persona` 为 false，并且 `inheritsParentContext: false`。不可变的 `agentRouteDefaults` 会在模型覆盖与确切路由预检前，把配置的 provider／model 基线公开给 `dsh-tool-subagent`；`start()` 则为直接调用方与 `maxTokens` 独立应用同一份配置默认值。Agent 路由值通过显式白名单跨越 SDK 协议；子进程仍是另一进程里的全新运行时，唯一从父 agent 本身派生的值是工作区 cwd。基于本提供方的 `dsh-tool-subagent` 部署应设置 `maxDepth: 'provider-managed'`——子 harness 拥有自己的递归预算。
+

-## 失败诊断
-
-首行遵循共享固定格式：
-
-```text
-Subagent failure (provider: DSH SDK; stage: <stage>; category: <category>)
-```
-
-共享结果边界会把完整文本限制在 4096 个 UTF-8 字节以内。提供方从实际拥有失败的操作派生 `initialize`、`session-run` 或 `shutdown`。在 initialize 或 session run 期间，`SdkProtocolError` 与 JSON-RPC 错误响应映射为 `protocol`，`TransportClosedError` 映射为 `transport`，其他异常使用 `unknown`。shutdown 拒绝使用 `unknown`：SDK 客户端会把协议 shutdown 失败留在 Host 诊断中，因此只有运行时进程释放能让 `close()` 拒绝。分类绝不读取错误消息，因此 `TransportClosedError` 携带的 stderr tail、路径、任务内容、环境值、凭证与协议 payload 都只留在 Host。请求超时分类会推迟到本提供方实际配置或传播 request timeout 时；当前 SDK launch 会无限等待普通请求。
-
-成功结果与本地取消会省略诊断。启动和 shutdown 拒绝会在 Error 消息中使用同一安全行，同时把原始 cause 留在内部。带诊断的子 `aborted` 结果仍保持 `aborted`；一次性 Job adapter 会把它判为 failed，而不带诊断的本地取消仍是 killed。
-
-## 能力与上下文
-
-提供方声明 `agentOptions: true`，同时保持 `outputSchema`/`depthLimit`/`toolFilter`/`persona` 为 false，并且 `inheritsParentContext: false`。不可变的 `agentRouteDefaults` 会在模型覆盖与确切路由预检前，把配置的 provider／model 基线公开给 `dsh-tool-subagent`；`start()` 则为直接调用方与 maxTokens 独立应用同一份 Config 默认值。Agent 路由值通过显式白名单跨越 SDK 协议；子进程仍是另一进程里的全新运行时，唯一从父 Agent 本身派生的值是工作区 cwd。基于本提供方的 `dsh-tool-subagent` 部署应设置 `maxDepth: 'provider-managed'`——子 harness 拥有自己的递归预算。

+本节解释后端如何驱动子 Harness 运行时，以及可观察行为从何而来；完整约定见[使用本包](#use-this-package)。
+
+### 设计理念
+
+- **完整 harness 对等体。** 每个子进程都是独立进程中的完整 Harness 运行时——拥有自己的组合、会话、模型路由与工具；只有解析后的工作目录与 `initialize` 路由从父级跨越。
+- **每次运行一个运行时。** 每次运行都 spawn 全新运行时进程；没有进程池。
+- **JSON-RPC 协议格式是序列化边界。** 同进程 subagent 值不会为防御目的克隆；协议才是校验不可信输入的地方。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：config schema、提供方注册 |
+| [`src/run.ts`](src/run.ts) | SDK 运行生命周期、答案提取与停止原因映射 |
+
+### 运行流程
+
+一次启动会在 spawn 前解析子进程工作目录与一条进程级 SDK 路由。`request.agentOptions` 中每个已声明字段（`provider`、`model`、`reasoningEffort` 或 `maxTokens`）都会覆盖对应的提供方实例默认值；省略时保留已配置的提供方／模型与可选上限，而推理强度只有在请求提供时才会出现。随后，提供方通过 SDK 客户端 spawn 运行时，并在履行前完成 `initialize` 握手，其中包括确切模型与推理强度校验。路由、spawn、握手或发布前取消失败时，只会在子进程被回收后拒绝；工作目录解析失败则会在尚未 spawn 任何内容时拒绝。发布后，提供方拥有一段 SDK 活动，并从子会话事件中读取答案：最后一条完整且非空的 `assistant/message`（记录 usage 的空内容消息会被跳过）；若没有这类消息，则取累积的 `text-delta` 流。dispose（资源释放）是幂等的：先在本地把结果确定为 `aborted`，发出有界的协议 `shutdown` 请求，再经 stdin EOF → SIGTERM → SIGKILL 升级到实际退出。
+
+### 停止原因映射
+
+子进程最后一个 `turn/end` 的原因会映射进共享的停止原因词汇，实现见 [`src/run.ts`](src/run.ts)。
+
+### 进程边界
+
+子进程环境以子进程 seam 的已清理凭据父环境为基础，并在清除之后合并显式 `config.env` 值。子进程由 SDK 客户端 spawn，而不是经由 `ctx.subprocess`——这是 SDK 托管传输的文档化例外——因此本后端会自行执行环境清理。

-The fork provider creates an in-process child seeded with the parent's completed conversation turns. It shares all run mechanics with spawn; the session seed is the only behavioral difference.
+## Summary
 
-## Seed boundary
+`dsh-subagent-fork-in-process` is an in-process subagent backend that seeds each child with the parent's completed conversation turns: the child sees every finished turn and none of the in-flight one, so follow-up work builds on the conversation without duplicating it. A delegation tool reaches it under the `fork` provider name, and its behavior matches the spawn backend except for the session seed. Choose it when a subtask continues this conversation; choose spawn when the child must stand alone. The seed is a one-time snapshot taken at fork time: later parent turns never reach the child.
 
-The parent's current tool-calling turn is still open when a subagent starts: its log contains the assistant tool call but not the matching tool result or `turn/end`. Copying that raw log would give the child an invalid, unbalanced session.
+## Table of Contents
 
-Fork therefore computes the contiguous prefix ending at the last `turn/end`. The child sees all completed parent turns and none of the in-flight turn. If the parent has not completed a turn yet, the seed is empty and the child behaves like a fresh spawn.

+- [Further Exploration](#further-exploration)
+- [Model Experience](#model-experience)
+- [Known Limitations and Deferred Work](#known-limitations-and-deferred-work)
+- [Dev Note](#dev-note)
 
-The seed transfers conversation history only. The child still receives a fresh flat registration scope; it does not inherit the parent's tool restrictions or authority.
+-----
 
-## Start and capabilities
+<a id="use-this-package"></a>
+## Use this package
 
-`start(request)` passes the completed-turn seed to [`startInProcessRun`](../subagent-in-process-driver/README.md) and awaits child publication. The shared driver owns cancellation, depth, customization, result reading, and disposal.
+Mount this backend when delegated work must build on the parent's conversation. The common path mirrors spawn: load the subagent service and this backend, then point a delegation tool such as `dsh-tool-subagent` at the `fork` provider.
 
-Fork advertises `{ agentOptions: true, outputSchema: true, depthLimit: true, toolFilter: true, persona: true }`, identical to spawn.
+### When to choose it
 
-## Config
+Choose fork when the child needs the conversation's completed turns — a follow-up analysis, a review, a continuation. Choose spawn when the child should start clean, or an out-of-process backend when the child must not share this process. The seed carries conversation history only: the child still gets a fresh tool scope and none of the parent's authority.
 
-| Key | Meaning |
+### Seed boundary
+
+The seed ends at the parent's last completed turn. A parent's current tool-calling turn is still open when a subagent starts, so that in-flight turn is never included; before the first completed turn the seed is empty and the child behaves like a fresh spawn.
+
+### Minimal configuration
+
+Load the subagent service and this backend, then configure a delegation tool. This composition exposes a `subagent` tool backed by fork:
+
+```yaml
+- name: '@deepseek-ai/dsh-subagent'
+- name: '@deepseek-ai/dsh-subagent-fork-in-process'
+- name: '@deepseek-ai/dsh-tool-subagent'
+  config:
+    provider: fork
+```
+
+| Field | Default | Meaning |
+|---|---|---|
+| `providerName` | `fork` | Provider name registered on `ctx.subagents` |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-subagent-fork-in-process) is the exhaustive source for every accepted field and its JSDoc.
+
+### What a fork delegation does
+
+One tool call starts one child seeded with the completed turns and waits for its result: the child sees the conversation up to the parent's last completed turn, works in its own session, and the parent receives only its final output — or an errored tool result for cancellation, refusal, token-limit truncation, or startup rejection. The seed is captured once at start; later parent turns never reach the child.
+

+
+<a id="understand-the-implementation"></a>
+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the backend and where the behavior in [Use this package](#use-this-package) comes from.
+
+### Design concept
+
+One difference from spawn, expressed as data: the backend computes the balanced completed-turn prefix of the parent's log and hands it to the shared in-process driver as the child's session seed. Because live sequence numbers equal array indexes, the prefix stays a valid seed beginning at sequence zero, and the driver records its length so the result reader never mistakes a seeded parent message for child output.
+
+### Source map
+
+| File | Role |
 |---|---|
-| `providerName` | Registry name on `ctx.subagents` (default `fork`). |
-See [`dsh-subagent-spawn-in-process`](../subagent-spawn-in-process/README.md) for the run lifecycle, model inheritance, and depth tracking — all shared.
+| [`src/index.ts`](src/index.ts) | Provider registration: prefix computation, `Config` schema, capability declaration |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion |
 
+### Run flow
+
+On `start`, the prefix is sliced from the parent's event log up to and including the last `turn/end`; the shared driver then creates the child with that seed, applies the same persona, tool-filter, and structured-output setup, drives one task, reads the child's own final output, and disposes quiescently. The provider advertises `agentOptions` plus the same output, depth, filter, and persona capabilities as spawn. `prepareContinuable` captures the prefix once, at creation, because it becomes part of the child's own durable transcript.
+
+### One-shot binding
+
+The base bundle and ACP/headless examples bind this provider to `backgroundMode: one-shot`: a continuable fork child carries the child-scoped `report` tool and its prompt section before the inherited history, defeating byte-identical prefix reuse. The CLI presets retain `continuable` fork and accept that prefix loss ([cache-preserving fork Agent Note](../../../.agents/notes/implemented/architecture/2026-08-10-fork-children-stay-one-shot.md)).

 ## Model Experience
 
 ### Child-agent history and envelope
 
 #### What the model sees
 
-The child receives the parent's balanced completed-turn surface prefix, then the new task content verbatim. A configured persona shadows prompt text in the child's fresh scope; a tool restriction filters its global wire schemas, executable lookup, and Code Mode SDK bindings but not standalone guidance. The parent's tool view and authority are not inherited. An optional structured-output request adds its child-only contract. The parent's current in-flight turn is excluded.

 #### Token effect
 
-Forking duplicates retained completed history into separate child requests; the child then accumulates its own tokens independently. Persona changes repeated prompt cost, filtering changes schema or generated SDK cost, and a first-turn fork has no inherited history.

 #### KV Cache effect
 
-The child may reuse the inherited byte-identical prefix under the same provider and model. Persona, tool-filter, generated-SDK, or route changes may invalidate reuse before inherited history; later child history is append-only. The base bundle and ACP/headless examples bind this provider to `backgroundMode: one-shot`, because a continuable child additionally carries the child-scoped `report` tool and its prompt section — deltas that precede the inherited history and so invalidate all of it. The CLI presets retain `continuable` fork and therefore accept that prefix loss ([the cache-preserving fork Agent Note](../../../.agents/notes/implemented/architecture/2026-08-10-fork-children-stay-one-shot.md)).

-fork 提供方会创建一个进程内子 agent（智能体），并以父 agent 已完成的对话轮次作为初始内容。它与 spawn 共用全部运行机制；唯一的行为差异是会话初始内容。
+## 概述
 
-## 初始内容边界
+`dsh-subagent-fork-in-process` 是一个进程内 subagent 后端：它以父级已完成的对话轮次作为每个子 agent（智能体）的初始内容——子 agent 能看到所有已完成轮次，但看不到进行中的轮次，因此后续工作可以在对话基础上继续，而无需复制对话。委派工具以 `fork` 提供方名称找到它，其行为与 spawn 后端一致，唯一差异是会话初始内容。当子任务延续当前对话时选择它；当子 agent 必须独立运行时选择 spawn。初始内容是 fork 时的一次性快照：此后父级记录的任何内容都不会到达子 agent。
 
-subagent 启动时，父 agent 当前的工具调用轮次仍未结束：其日志包含 assistant 工具调用，但尚无匹配的工具结果或 `turn/end`。直接复制这份原始日志会给子 agent 一个无效且不平衡的会话。
+## 目录
 
-因此，fork 会计算截至最后一个 `turn/end` 的连续前缀。子 agent 能看到父 agent 所有已完成轮次，但看不到进行中的轮次。如果父 agent 尚未完成任何轮次，初始内容为空，子 agent 的行为与全新 spawn 相同。

-## 启动与能力
+<a id="use-this-package"></a>
+## 使用本包
 
-`start(request)` 将已完成轮次的初始内容传给 [`startInProcessRun`](../subagent-in-process-driver/README.zh.md)，并等待子 agent 发布。共享驱动器负责取消、深度、定制、结果读取和 dispose（资源释放）。
+当委派的工作必须建立在父级对话之上时，挂载此后端。常用路径与 spawn 相同：加载 subagent 服务与本后端，再把 `dsh-tool-subagent` 之类的委派工具指向 `fork` 提供方。
 
-fork 声明 `{ agentOptions: true, outputSchema: true, depthLimit: true, toolFilter: true, persona: true }`，与 spawn 相同。
+### 何时选择
 
-## 配置
+当子 agent 需要对话的已完成轮次时——后续分析、审查、延续——选择 fork。当子 agent 应全新开始时选择 spawn；当子 agent 不能共享本进程时选择进程外后端。初始内容只传递对话历史：子 agent 仍获得全新的工具作用域，且不继承父级的任何权限。

+一次工具调用启动一个以已完成轮次为初始内容的子 agent，并等待其结果：子 agent 能看到截至父级最后一个已完成轮次的对话，在自有会话中工作，父级只接收其最终输出——取消、拒绝、token 上限截断或启动被拒时则收到出错的工具结果。初始内容在启动时只捕获一次；此后的父级轮次绝不会到达子 agent。

+
+本节解释后端背后的设计决策，以及[使用本包](#use-this-package)中行为的来源。
+
+### 设计理念
+
+与 spawn 的差异只有一处，且以数据表达：后端计算父级日志的已配平已完成轮次前缀，并把它作为子 agent 的会话初始内容交给共享进程内驱动器。由于实时序号等于数组下标，前缀始终是自序号零开始的合法初始内容；驱动器记录其长度，使结果读取器不会把作为初始内容的父级消息误认为子 agent 输出。
+
+### 源码地图
+
+| 文件 | 职责 |
 |---|---|
-| `providerName` | `ctx.subagents` 上的注册表名称（默认 `fork`）。 |
-运行生命周期、模型继承与深度跟踪均为共享行为，见 [`dsh-subagent-spawn-in-process`](../subagent-spawn-in-process/README.zh.md)。
+| [`src/index.ts`](src/index.ts) | 提供方注册：前缀计算、`Config` schema、能力声明 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件 |
 
+### 运行流程
+
+`start` 时，从父级事件日志中截取截至最后一个 `turn/end` 的前缀；共享驱动器随后以该初始内容创建子 agent，应用相同的 persona、工具过滤器与结构化输出设置，驱动一项任务，读取子 agent 自身的最终输出，并完全停稳地 dispose。该提供方声明 `agentOptions`，以及与 spawn 相同的输出、深度、过滤与 persona 能力。`prepareContinuable` 在创建时只捕获一次前缀，因为它会成为子 agent 自身持久 transcript（文本记录）的一部分。
+
+### 一次性绑定
+
+base bundle 与 ACP/headless 示例在委派工具上把本提供方绑定为 `backgroundMode: one-shot`：可继续 fork 子 agent 会在继承历史之前携带子级作用域的 `report` 工具及其提示词 section，从而破坏逐字节前缀复用。CLI preset 保留可继续 fork，并接受该前缀损失（见[保持 fork 缓存的 Agent Note](../../../.agents/notes/implemented/architecture/2026-08-10-fork-children-stay-one-shot.zh.md)）。

-This package is the shared run driver for the two in-process providers. Spawn passes no session seed; fork passes the parent's completed-turn prefix. Everything else—depth, child creation, optional child customization, result reading, cancellation, and disposal—has one implementation here.
+## Summary
 
-## Start contract
+`dsh-subagent-in-process-driver` is the shared run driver behind the two in-process subagent backends: it creates one child agent through the host's agent factory, applies per-child customization, drives one task to completion, and returns the child's own final output with a single quiescent disposal path. Spawn calls it with no session seed; fork calls it with the parent's completed-turn prefix. It is a library, not a standalone feature: provider backends call `startInProcessRun`, and nothing in a composition configures it. Read this page to understand the run lifecycle both in-process backends share.
 
-`startInProcessRun(request, options): Promise<SubagentRun>` fulfills only after the child is published in `ctx.agents`. A rejected start has already quiesced the agent factory's unpublished creation transaction, so the caller never receives a half-created handle.

+## Use this package
+
+You reach this package through a provider backend, not a composition: `dsh-subagent-spawn-in-process` and `dsh-subagent-fork-in-process` each call `startInProcessRun(request, options)` and own everything around it. This page documents the lifecycle both share so you can read one backend's behavior and reason about the other.
+
+### What one run provides
+
+One call starts and drives one one-shot child. Fulfillment means the child is already published in `ctx.agents` and the caller owns the returned run; a rejected start has already quiesced the unpublished creation, so no half-created child survives. The run exposes the child's id and live agent, a `result` promise, and a `dispose()` that stops the loop, removes the agent and session, and unwinds scoped registrations.
+
+### The one input
+
+`InProcessRunOptions` is `{ seed?: SessionEvent[] }` — a fork seed of balanced parent events. Spawn omits it; fork supplies the completed-turn prefix and records its length so the result reader never mistakes seeded parent messages for child output.
+
+### What the child gets
+
+The child receives the parent's working-directory/session lineage and inherits the parent provider, model, reasoning effort, and output-token cap unless `request.agentOptions` overrides them. It gets a fresh flat registration scope: parent tool restrictions and authority are not imported. A run carries the parent's explicit sandbox override and `'never'` approval pin into the child and appends a per-run descriptor inside the child's initial turn.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the driver's lifecycle contract and the structured-output runtime; the observable behavior is covered in [Use this package](#use-this-package).
+
+### Start contract
 
 The driver follows this sequence:
 
 1. Validate the parent depth and optional absolute `maxDepth`, then derive child depth as parent depth plus one and persist it in the child session header.
-2. Call `parent.ctx.agents.create` directly, passing the required request signal into the factory's creation transaction.
+2. Create the child through the host agent factory with the caller's required signal threaded into the creation transaction.
 3. During that transaction's unpublished setup window, install the requested persona, tool restriction, and structured-output runtime.
-4. Publish the child, retain the returned `AgentHandle`, and drive one task with `child.followup(prompt)` followed by `child.whenIdle()`.
-5. Read the child's own output — its last non-empty assistant message (an empty-content message that records usage is skipped), or its accumulated assistant text when no such message exists — and the final durable turn reason from the complete owned child run, excluding any fork seed.
+4. Publish the child, retain the returned handle, and drive one task.
+5. Read the child's own output — its last non-empty assistant message, or its accumulated assistant text when none exists — and the final durable turn reason from the complete owned run, excluding any fork seed.
 
-The child gets the parent's working-directory/session lineage and inherits the parent provider, model, reasoning effort, and output-token cap unless `request.agentOptions` overrides them. It gets a fresh flat registration scope: parent ownership does not import parent tool restrictions or establish an authority subset.
+### Cancellation and ownership
 
-This result boundary is valid because the provider owns an isolated child lifecycle from publication through quiescence. Steering submitted during that lifecycle belongs to the child run; the provider does not pretend the initial follow-up alone owns its output.
+The required request signal covers both startup and the live run. Before publication, the creation transaction observes it, rolls back, and rejects; the driver re-checks once after publication to close the handoff race, then installs a minimal live-run listener. After fulfillment the caller owns the run: provider unload does not revoke it, and `dispose()` removes the abort listener, records cancellation, and delegates to the handle's memoized quiescence transaction, which stops the loop, removes the agent and session, and unwinds scoped registrations. Cancellation owns every non-completed in-flight outcome and reports `aborted`; an already-completed turn remains completed.
 
-The driver applies the seam's [delegated policy](../subagent/README.md#delegated-policy) through the shared child-agent helpers: it captures the parent's explicit sandbox override and the `'never'` approval pin before child creation and appends the source-tagged events during unpublished setup, after any fork history and before session publication. See the [delegation-policy decision](../../../.agents/notes/implemented/feature/2026-07-25-subagent-policy-inheritance.md).
+### Structured output
 
-## Cancellation and ownership
+`attachStructuredRuntime(childCtx, schema)` installs the whole contract in the child's scope: a `structured_output` tool validates and stages the model's value against the requested schema; a trailing first-party order-9900 system-prompt section tells the child the tool call is the terminal answer; a `tools/result` observer commits a staged value only after the authoritative final tool result succeeds, including the enclosing `run_code` result for Code Mode sub-dispatch; and a monotonic tool guard blocks later calls after capture. A clean turn that never commits the required value reports `error`; the driver does not re-prompt. All registrations ride the child fiber and disappear with it.
 
-The required request signal covers both startup and the live run. Before publication, `AgentCreationTransaction` observes it, rolls back, and rejects. The factory detaches that creation-only listener before returning; the driver immediately checks the signal once more before installing a minimal live-run listener, closing the handoff race. After publication, abort cancels the child.
+### Source map
 
-After fulfillment, the caller owns the run. Provider-plugin unload does not revoke it. `dispose()` removes the live abort listener, records cancellation, and delegates to the returned `AgentHandle.dispose()`, whose memoized quiescence transaction stops the loop, removes the agent and session, and unwinds scoped registrations. Cancellation owns every non-completed in-flight outcome and reports `aborted`; an already-completed turn remains completed.

-## Spawn and fork inputs
+</details>
 
-`InProcessRunOptions` is `{ seed?: SessionEvent[] }`. Spawn omits it. Fork supplies a balanced completed-turn prefix and records its length so the result reader never mistakes a seeded parent message for child output.
+-----
 
-Depth enforcement is internal to `startInProcessRun`: it reads the parent depth via `delegationDepthOf` (the persisted `SessionHeader.delegationDepth` is authoritative; runtime `AgentOptions.subagentDepth` may deepen but never lower it, so a resumed child keeps its budget), treats absence as top-level depth zero, rejects malformed stored values, and reports an attempted child depth above `maxDepth`. An unrepresentable depth above the safe-integer domain is a `RangeError`. The child depth is written to the child header, so it survives persistence and resume.

+## Further Exploration
 
-## Structured output
+Read these pages when the package-level contract is not enough; they move from the shared subagent model to the backends built on this driver and the delegation-policy decision.
 
-`attachStructuredRuntime(childCtx, schema)` installs the whole contract in the child's scope:

-- A `structured_output` tool registered with the requested schema validates and stages the model's value.
-- A trailing first-party order-9900 system-prompt section tells the child that the tool call is the terminal answer.
-- Both contributions are ordinary child-scoped registrations. An expert `system-prompt/assemble` listener may replace them and therefore owns preserving the structured-output protocol for that child.
-- A `tools/result` observer commits a staged value only after that execution's authoritative final tool result succeeds, including the enclosing `run_code` result for Code Mode sub-dispatch.
-- A monotonic tool guard blocks later calls after capture, and the structured-output execution's `concludeTurn()` marker ends the turn after the result commits.

-本包是两个进程内提供方共用的运行驱动器。spawn 不传入会话初始内容；fork 传入父 agent（智能体）已完成轮次的前缀。其余机制，包括深度、子 agent 创建、可选的子 agent 定制、结果读取、取消和 dispose（资源释放），都在此共用同一套实现。
+## 概述
 
-## 启动约定
+`dsh-subagent-in-process-driver` 是两个进程内 subagent 后端共用的运行驱动器：它通过宿主的 agent 工厂创建一个子 agent，应用按子 agent 的定制，把一项任务驱动到完成，并以单一完全停稳的 dispose（资源释放）路径返回子 agent 自身的最终输出。spawn 调用它时不传入会话初始内容；fork 调用它时传入父级已完成轮次的前缀。它是库而非独立功能：提供方后端调用 `startInProcessRun`，组合中没有任何东西配置它。阅读本页可理解两个进程内后端共享的运行生命周期。
 
-`startInProcessRun(request, options): Promise<SubagentRun>` 只在子 agent 发布到 `ctx.agents` 后才兑现。启动被拒绝时，agent 工厂的未发布创建事务已经完全停稳，因此调用方绝不会收到创建到一半的句柄。

+## 使用本包
+
+你通过提供方后端而非组合到达本包：`dsh-subagent-spawn-in-process` 与 `dsh-subagent-fork-in-process` 各自调用 `startInProcessRun(request, options)` 并拥有其外围的一切。本页记录两者共享的生命周期，使你读懂一个后端的行为后即可推断另一个。
+
+### 一次运行提供什么
+
+一次调用启动并驱动一个一次性子 agent。调用兑现意味着子 agent 已发布到 `ctx.agents`，调用方拥有返回的运行；启动被拒绝时，未发布的创建已经完全停稳，因此不会有创建到一半的子 agent 存活。运行暴露子 agent 的 id 与在线 agent、一个 `result` promise，以及一个 `dispose()`——它会停止循环、移除 agent 与会话，并撤销作用域内的注册。
+
+### 唯一输入
+
+`InProcessRunOptions` 的形态为 `{ seed?: SessionEvent[] }`——fork 的已配平父级事件初始内容。spawn 省略该值；fork 提供已完成轮次前缀并记录其长度，使结果读取器不会把作为初始内容的父级消息误认为子 agent 输出。
+
+### 子 agent 获得什么
+
+子 agent 获得父级的工作目录/会话谱系，除非 `request.agentOptions` 覆盖，否则继承父级的提供方、模型、推理等级与输出 token 上限。它获得全新的扁平注册作用域：父级工具限制与权限不会被导入。一次运行会把父级显式的沙箱覆盖项与 `'never'` 审批钉定带入子 agent，并在子 agent 的初始轮次内追加一份按运行的描述符。

-1. 校验父 agent 深度和可选的绝对 `maxDepth`，然后把子 agent 深度推导为父 agent 深度加一，并将其持久化到子 agent 会话 header。
-2. 直接调用 `parent.ctx.agents.create`，把必需的请求信号传入工厂的创建事务。
-3. 在该事务未发布的设置窗口中，安装请求的 persona、工具限制和结构化输出运行时。
-4. 发布子 agent，保留返回的 `AgentHandle`，并通过先调用 `child.followup(prompt)`、再调用 `child.whenIdle()` 来驱动一项任务。
-5. 从完整的自有子运行中读取子 agent 自身的输出——最后一条非空 assistant 消息（记录 usage 的空内容消息会被跳过），若没有这类消息则取其累积的 assistant 文本——以及最终持久化的轮次原因，并排除任何 fork 初始内容。

 English | [中文](README.zh.md)
 
-The spawn provider creates a fresh child `Agent` in the current process. The child has its own session, sees no parent conversation history, and reuses the host's agent factory and LLM/tool services.
+## Summary
 
-## Behavior
+`dsh-subagent-spawn-in-process` is an in-process subagent backend: it runs each delegated task in a fresh child agent that shares this process and its agent factory, LLM, and tool services. The child starts with an empty conversation, so a task prompt must stand alone; it inherits the parent's working directory, session lineage, provider, model, reasoning effort, and output-token limit unless `request.agentOptions` overrides them. A delegation tool or API call reaches it under the `spawn` provider name. Choose it for the cheapest delegation transport; choose the fork backend when the child must build on the parent's completed conversation turns.
 
-`start(request)` delegates to [`startInProcessRun`](../subagent-in-process-driver/README.md) with no seed and awaits publication before returning. The child receives parent working-directory/session lineage and inherits the parent provider, model, reasoning effort, and output-token limit unless `request.agentOptions` overrides them, but starts with an empty conversation.
+## Table of Contents
 
-The shared driver owns depth checking, persona and tool-filter setup, structured output, required-signal cancellation, one-shot execution, result reading, and quiescent disposal. A startup rejection leaves no published child; provider unload after fulfillment does not revoke the holder-owned run.

-## Capabilities
+-----
 
-Spawn advertises `{ agentOptions: true, outputSchema: true, depthLimit: true, toolFilter: true, persona: true }` because it controls the child's creation window and can enforce all five features.
+<a id="use-this-package"></a>
+## Use this package
 
-## Config
+Mount this backend in a composition that delegates work to fresh in-process children. The common path is explicit: load the subagent service and this backend, then point a delegation tool such as `dsh-tool-subagent` at the `spawn` provider.
 
-| Key | Meaning |
+### When to choose it
+
+Choose the spawn backend when the child needs no parent conversation and running in this process is acceptable. Avoid it when the child must build on completed parent turns — the fork backend seeds that history — or when the child must run outside this process, which the out-of-process backends provide. Because the child inherits the parent's working directory and LLM selection by default, a self-contained prompt behaves exactly as written.
+
+### Minimal configuration
+
+Load the subagent service and this backend, then configure one delegation tool per target. This is the smallest composition that exposes a `subagent` tool backed by spawn:
+
+```yaml
+- name: '@deepseek-ai/dsh-subagent'
+- name: '@deepseek-ai/dsh-subagent-spawn-in-process'
+- name: '@deepseek-ai/dsh-tool-subagent'
+  config:
+    provider: spawn
+```
+
+| Field | Default | Meaning |
+|---|---|---|
+| `providerName` | `spawn` | Provider name registered on `ctx.subagents` |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-subagent-spawn-in-process) is the exhaustive source for every accepted field and its JSDoc.
+
+### What a delegation does
+
+One tool call starts one child and waits for its result: the child works in its own session and the parent receives only its final output, or an errored tool result when the run is cancelled, refused, truncated by its token limit, or rejected at startup. A rejected start leaves no published child; a completed run is disposed after its result is collected.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the backend is built and where the behavior in [Use this package](#use-this-package) comes from; the shared mechanics belong to the in-process driver.
+
+### Design concept
+
+One separation: this backend contributes only the provider registration and the decision to start fresh, while every run mechanic — depth checking, child creation, per-child customization, structured output, cancellation, result reading, and disposal — lives in `dsh-subagent-in-process-driver`. The agent factory's creation transaction owns the unpublished setup window and its rollback; after publication the caller owns the run.
+
+### Source map
+
+| File | Role |
 |---|---|
-| `providerName` | Registry name on `ctx.subagents` (default `spawn`). |
+| [`src/index.ts`](src/index.ts) | Provider registration: `Config` schema, capability declaration, `start()` |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion |
 
+### Run flow
+
+A start request resolves through the subagent service, then the shared driver validates depth, mints a child session id, creates the child through the host agent factory with the caller's signal, applies persona, tool filter, and structured output inside the creation window, publishes the child, drives one task, reads the child's own final output, and disposes the handle quiescently.
+
+### Ownership and scope
+
+The child gets a fresh flat registration scope: parent tool restrictions and authority are never imported, and the filter the tool applies is composition, not a parent-derived grant. The backend advertises all five start-time capabilities, including `agentOptions`, because it controls the child's creation window and can enforce each one.

 ### Child-agent request
 
 #### What the model sees
 
-The fresh child receives the standalone task content verbatim, inherits the parent provider, model, reasoning effort, output-token limit, and workspace by default, and sees the global prompt with any configured child-scoped persona shadow. A tool filter removes global wire schemas, executable lookup, and Code Mode SDK bindings for that child but leaves independently registered guidance. It receives zero parent conversation messages; the filter is visibility/composition, not an authority grant inherited from the parent.

No parent conversation message is included; the filter is composition, not an inherited authority grant.
 
 #### Token effect
 
-The child pays for a new independent context and history; no parent-history tokens are duplicated. Persona changes this child's repeated prompt cost, while filtering changes its schema or generated SDK cost.

-spawn 提供方会在当前进程中创建一个全新的子 `Agent`。子 agent（智能体）有自己的会话，看不到父 agent 的对话历史，并复用宿主的 agent 工厂及 LLM（大语言模型）/工具服务。
+## 概述
 
-## 行为
+`dsh-subagent-spawn-in-process` 是一个进程内 subagent 后端：它在当前进程中运行每个委派任务，子 agent（智能体）是一个全新子 `Agent`，复用宿主的 agent 工厂及 LLM（大语言模型）/工具服务。子 agent 以空对话开始，因此任务提示词必须自足；除非 `request.agentOptions` 覆盖，否则它继承父 agent 的工作目录、会话谱系、提供方、模型、推理等级与输出 token 上限。委派工具或 API 调用以 `spawn` 提供方名称找到它。需要成本最低的委派传输时选择它；需要子 agent 建立在父级已完成对话轮次之上时，请选择 fork 后端。
 
-`start(request)` 不传入 seed，直接委托给 [`startInProcessRun`](../subagent-in-process-driver/README.zh.md)，并在子 agent 发布后才返回。子 agent 获得父 agent 的工作目录/会话谱系；除非 `request.agentOptions` 覆盖，否则还会继承父 agent 的提供方、模型、推理强度与输出 token 上限，但以空对话开始运行。
+## 目录
 
-共享驱动器负责深度检查、persona 与工具过滤器设置、结构化输出、通过必需的信号执行取消、单次执行、结果读取和完全停稳后的 dispose（资源释放）。启动遭拒不会留下已发布的子 agent；启动调用兑现后卸载提供方，也不会撤销由持有方拥有的运行。

+## 使用本包
 
-## 配置
+在需要把工作委派给全新进程内子 agent 的组合中挂载此后端。常用路径是显式的：加载 subagent 服务与本后端，再把 `dsh-tool-subagent` 之类的委派工具指向 `spawn` 提供方。
 
-| 键 | 含义 |
+### 何时选择
+
+当子 agent 不需要父级对话、且可以接受在本进程内运行时，选择 spawn 后端。当子 agent 必须建立在已完成父级轮次之上时——fork 后端会提供这些历史——或必须在本进程之外运行时（进程外后端提供此能力），请避免使用它。由于子 agent 默认继承父级的工作目录与 LLM 选择，自足的提示词会按原样生效。
+
+### 最小配置
+
+先加载 subagent 服务与本后端，再为每个目标配置一个委派工具。这是暴露由 spawn 支撑的 `subagent` 工具的最小组合：
+
+```yaml
+- name: '@deepseek-ai/dsh-subagent'
+- name: '@deepseek-ai/dsh-subagent-spawn-in-process'
+- name: '@deepseek-ai/dsh-tool-subagent'
+  config:
+    provider: spawn
+```
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `providerName` | `spawn` | 注册到 `ctx.subagents` 的提供方名称 |
+
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-subagent-spawn-in-process)是每个受支持字段及其 JSDoc 的穷尽式真源。
+
+### 一次委派会做什么
+
+一次工具调用启动一个子 agent 并等待其结果：子 agent 在自有会话中工作，父级只接收其最终输出；若运行被取消、拒绝、被 token 上限截断或在启动时被拒，则收到出错的工具结果。被拒绝的启动不会留下已发布的子 agent；完成的运行在结果收集后即被 dispose（资源释放）。

+一个分离：本后端只贡献提供方注册与「全新开始」的决定，其余全部运行机制——深度检查、子 agent 创建、按子 agent 定制、结构化输出、取消、结果读取与 dispose——都在 `dsh-subagent-in-process-driver` 中。agent 工厂的创建事务拥有未发布设置窗口及其回滚；发布之后，调用方拥有该运行。

-The subagent seam lets one agent delegate work to a child through a named provider. Callers use one service API (`ctx.subagents`); providers decide whether the child runs in this process, in another process, or through a future transport.
+## Summary
 
-The [subagent family overview](../README.md) maps implementations and model-facing consumers. This package owns the provider registry, shared request and result contracts, durable descriptors, and continuable-child orchestration. Multiple named providers may coexist behind that contract.
+`dsh-subagent` is the service behind child-agent delegation: an agent hands a task to a named child, collects the finished result, and — for continuable children — keeps sending follow-up work across turns. Multiple providers coexist under one contract, so a single composition can offer in-process children, out-of-process ACP or SDK children, and real Codex or Claude Code children side by side. Children come in two shapes: one-shot runs that settle with a single result, and continuable children whose durable session accepts later messages and can be interrupted. The same service answers discovery questions — which children exist, their mode, activity, and lineage — without loading or resuming them. Mount it with at least one provider backend and a delegation tool; the backends and the model-facing tools live in sibling packages.

+## Use this package
+
+This package is the contract every delegation setup shares. You enable it by mounting the service together with one or more provider backends and the model-facing delegation tool; from then on, an agent can delegate work and the service routes each request to the named provider.
+
+### Enabling delegation
+
+Mount the service with a provider and the delegation tool. The provider registers under the name you configure (the in-process spawn backend defaults to `spawn`); the tool row names that provider so the model sees a static tool. A minimal one-shot setup:
+
+```yaml
+- name: '@deepseek-ai/dsh-subagent'
+- name: '@deepseek-ai/dsh-subagent-spawn-in-process'
+- name: '@deepseek-ai/dsh-tool-subagent'
+  config:
+    provider: spawn
+    toolName: subagent
+```
+
+An agent that calls the tool gets the child's final answer as the tool result. Mounting the service alone changes nothing: nothing can delegate until a provider and a tool are composed.
+
+### One-shot and continuable children
+
+One-shot children run once and settle with a single result, plus an optional structured output and a safe diagnostic on failure. A start request may override the child Agent's provider, model, reasoning effort, and output-token limit through `agentOptions`; every requested option requires the provider's matching capability. Continuable children keep a durable session and accept later messages in order: the caller receives a stable child id, sends follow-ups, and can interrupt the current turn without destroying the child. The tool row's `backgroundMode` picks the shape (`one-shot` by default, or `continuable` on providers that support it).
+
+### Following up, interrupting, and discovering
+
+Continuable children answer follow-up messages as their next turns, and the parent can interrupt a running turn or list its children at any time. Discovery covers both shapes: the service lists direct children and the full descendant tree — mode, activity, and lineage — reading live session state and optional persistence, without loading any child.
+
+### Failure and recovery
+
+Requests that need a capability the chosen provider lacks fail loudly at start rather than being silently ignored. A failed child run returns a stop reason, and provider backends add a safe diagnostic; a cancelled request settles as `aborted`. Children are isolated: a crashed or misbehaving child cannot corrupt the parent's session.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the service is built and where the observable behavior comes from; the full contract lives in [Use this package](#use-this-package).
+
+### Design concept
+
+- **One service, many providers.** The service is a named-provider registry; each backend registers under a unique name and a request picks one by name.
+- **Two child shapes.** One-shot runs transfer ownership at publication; continuable children keep a durable Session and at most one process-local Activation.
+- **Fulfillment is publication.** A provider's `start()` fulfills only after a real child exists, so the caller always owns a live run or nothing.
+- **Trusted same-process values.** Requests, descriptors, and results are borrowed immutable; serialization and hostile-input validation belong at process and wire boundaries.
+
+### Source map
+
+| File | Role |
 |---|---|
-| `registerProvider(provider)` | Register one trusted same-process implementation by name. Registration is effect-scoped; removing it prevents new starts but does not revoke runs already returned to callers. Duplicate names fail loud. |
-| `getProvider(name)` | Return the provider, or `undefined` when absent. |
-| `list()` | Return provider names in insertion order. |
-| `start(name, request)` | Validate an ordinary caller request, resolve its detached `one-shot` descriptor, then await the provider until a real one-shot child is published. Fulfillment returns a holder-owned `SubagentRun`; rejection means the provider has already cleaned every unpublished startup resource, while post-publication turn or infrastructure faults settle through the run. Continuable children never enter through this operation. |
-| `startContinuable(spec)` | Establish one durable continuable child and deliver its initial prompt. Resolves with `{ childId, messageId }` when the child's inbox accepts that prompt, without waiting for the turn to start or for the message to reach the Session log; any earlier failure rejects with no ids and rolls the child back entirely. A caller-reserved `childId` is rejected when the live registries or configured persistence already own it. Requires `ctx.agents`, session persistence, and a provider with the `prepareContinuable` capability. |
-| `followup(parent, childId, content, { source, signal })` | Deliver one later message from the exact live direct parent as the child's next FIFO turn, matching `Agent.followup()` terminology, and return the accepted `MessageId`. A resident child's inbox accepts it directly (waking a waiting Activation); an absent one cold-resumes from its persisted Session. Requires `ctx.agents`; cold resume also requires session persistence. |
-| `interrupt(targetSessionId, authority)` | Interrupt one live continuable child's current turn under a human durable parent address (`{ kind: 'user', parentSessionId }`) or an exact live ancestor Agent (`{ kind: 'ancestor', agent }`). Admission is synchronous and the effect asynchronous: it issues `Agent.cancel(cause, { keepInbox: true })` and returns without waiting for the target to observe the signal. Unclaimed pending inbox work, the Activation, and published descendants are preserved; work already claimed into the interrupted turn is not requeued. An absent target is an accepted no-op; a wrong parent address or a stale, self-targeting, or non-ancestor caller rejects with `UNAUTHORIZED`. |
-| `reportFrom(child, content, { delivery, signal })` | Deliver one selected message from the exact live continuable child to its exact live direct parent and return the accepted stable `MessageId`. Quiet delivery injects next-step context without waking; next-step delivery steers and wakes the parent. |
-| `registerContinuableSetup(contribution)` | Compose an optional deployment capability into each continuable child's unpublished scope, with immediate revocation from resident children. |
-| `drainContinuableDescendants(parents)` | Close admission below exact live host-owned parent Agents, stop only their visible continuable descendants, await materializations admitted below those roots through publication or rollback, then release the selected forests child-first. The cutoff lasts until each exact parent leaves the registry; unrelated parent forests and manager-wide admission remain live. |
-| `drainContinuableChildren(parent, childIds)` | Release only the named resident continuable direct children of one exact live parent, recursively and child-first. It does not close admission or touch siblings, accepts absent ids as no-ops, and rejects a resident child owned by another parent. This is teardown, so unlike `interrupt()` it does not preserve pending inbox work. |
-| `listChildren(parentSessionId, signal?)` | List direct session-backed subagents with their `one-shot`/`continuable` mode, `running`/`inactive` activity, origin-classified one-level `hasChildren` hint, and per-child diagnostics, ordered by `createdAt` then id, without loading or resuming them. Reads the live session store and optional session persistence directly (live-only enumeration when persistence is absent) and requires the mounted `sessionProjections` registry; it does not require `ctx.agents`, the continuation manager, or any query service. |
-| `listDescendants(rootSessionId, signal?)` | Flatten the root's complete session tree in stable pre-order from the same live-preferred corpus, adding each subagent entry's durable `parentId` and root-relative `depth`. Ordinary sessions and one-shot children remain traversal nodes so continuable descendants below them are discovered. Identity, diagnostics, dependencies, and cancellation follow `listChildren()`. |
+| [`src/index.ts`](src/index.ts) | Service entry: provider registry, start and continuation API, lifecycle events |
+| [`src/continuation.ts`](src/continuation.ts) | Continuable children: identity reservation, Activation residency, follow-up, interrupt, settlement |
+| [`src/types.ts`](src/types.ts) | Public request, result, and provider contracts |
+| [`src/descriptor.ts`](src/descriptor.ts) | Versioned `subagent/descriptor` session-event vocabulary |
+| [`src/child-agent.ts`](src/child-agent.ts) | Child composition, delegated policy, depth helpers |
+| [`src/list-children.ts`](src/list-children.ts) | Discovery over the live session store and optional persistence |
 
-`SubagentStartRequest.label` is an optional short durable display label for a session-backed one-shot child. Model-facing delegation supplies its existing `description`; lower-level callers need not invent presentation metadata. Continuable starts always carry their own required label. `signal` is required and is the canonical cancellation channel for a one-shot `start`. An abort before publication makes `start()` reject after rollback; an abort after publication cancels the returned run's remaining turn work without hiding its id. The request may also override the host Agent's provider, model, reasoning effort, and token limit, require structured output, cap delegation depth, restrict child tools, or set a child persona. Every requested optional feature requires its matching provider capability. For a continuable start or follow-up, the caller signal owns lookup, materialization, and admission only until inbox acceptance; afterward the manager owns the Activation independently, so later caller cancellation neither cancels the accepted turn nor disposes the child.
+### One-shot flow
 
-Follow-up authority comes from the exact live direct parent recorded in the child's durable header. Cold resume checks that authority before reconstruction and again in the final no-await inbox-admission span, so a parent unregistered or replaced during materialization cannot authorize delivery. The `source` on a follow-up records who supplied the delivered message and grants no authority.
+A request is validated against the provider's advertised capabilities, a durable descriptor is snapshotted, and the provider builds the child. Both in-process providers advertise `agentOptions`: child creation merges requested fields over the provider, model, and reasoning effort in the parent's latest logged request, falls back to creation options before the first request, and retains the configured token limit. A route change without an explicit effort clears the inherited route-owned effort so the selected model resolves its default. DSH SDK also advertises this capability and publishes immutable `agentRouteDefaults`, which supply its instance provider/model defaults before exact-route preflight; `start()` still owns direct callers and the output cap. ACP, Codex, and Claude Code reject agent-route overrides rather than silently ignoring them. On success the run is published and ownership transfers to the caller; on failure the provider rolls back every unpublished resource. The result carries the child's final output, an optional structured value, a stop reason, and an optional safe diagnostic.
 
-Same-process requests, descriptors, results, and event payloads are trusted typed values borrowed as immutable. The service does not clone or freeze them; serialization and hostile-input validation belong at actual process, worker, persistence, and model boundaries.
+### Continuable flow
 
-## Capabilities
+The manager reserves a child identity, resolves the durable descriptor, creates (or cold-resumes) the child Agent, installs it in an Activation, and submits the prompt. Later messages become FIFO turns through the child's own inbox; an absent Activation cold-resumes from the persisted session. When a resident Activation settles, the manager tells the child's direct parent in the parent's own turn stream.
 
-Start-time features are advertised in `provider.capabilities` because the service must reject an unsupported one-shot request before child creation:
+### Ownership and invariants
 
-- `agentOptions` — apply host-Agent provider, model, reasoning-effort, and output-token overrides.
-- `outputSchema` — enforce a structured final result.
-- `depthLimit` — enforce `maxDepth`.
-- `toolFilter` — apply the requested child tool restriction.
-- `persona` — apply a per-child persona.
+- **Publication is the boundary** — before it the provider owns the setup and must roll back on failure; after it the caller owns the run and must dispose it.
+- **Registration is effect-scoped** — removing a provider blocks new starts but never revokes accepted runs.
+- **Continuation authority is exact identity** — follow-ups require the exact live direct parent; reports require the exact live child.
+- **The descriptor is log-only** — a session event absent from model history and retained across compaction; a continuable descriptor records the resolved child provider, model, and reasoning effort explicitly for cold resume.
 
-Both in-process providers advertise `agentOptions`: child creation merges requested fields over the provider, model, and reasoning effort in the parent's latest logged request, falling back to its creation options before the first request and retaining its configured token limit. A route change without an explicit effort clears the inherited route-owned effort so the selected model resolves its default. DSH SDK also advertises the capability and publishes immutable `agentRouteDefaults` so its provider/model instance defaults become the Consumer's merge baseline before exact-route preflight; `start()` remains authoritative for direct callers and the output cap. ACP, Codex, and Claude Code advertise the capability as unsupported, so their transports reject configured or model-selected overrides instead of silently ignoring them.
+</details>
 
-Every in-process child is composed by one call, `applyChildComposition(childCtx, parent, composition)`, which joins the parent's agent-preset composition before applying the child's own persona and tool filter. The join is what gives the child its capabilities: with every model-facing row on the agent plane, a child that joined nothing would reach the model with an empty tool registry ([`dsh-agent-presets`](../../preset/agent-presets/README.md)). Taking the parent as a parameter is deliberate — it makes composing a child WITHOUT that join unrepresentable at the call sites, which is the defect the one call exists to prevent. A deployment composing no preset roster joins nothing and needs nothing: its model-facing rows sit in the host composition, where the child already resolves them through the tool registry's global layer.
+-----
 
-`childSessionMeta()` records the joined preset id on the child's durable header for the same reason a top-level session records its own: the preset decides the tool schemas and prompt sections the model saw, so a cold read of the child's history has to rebuild that composition rather than the deployment default. It is read from the parent's live scope chain, not from the parent header, because a parent that switched preset while blank runs on the newer composition while its header still names the older one.
+<a id="further-exploration"></a>
+## Further Exploration
 
-Continuable creation is the optional `SubagentProvider.prepareContinuable?()` method: its presence is the capability check, so the service rejects a configured continuable start on a provider without it, while a provider that has it may still serve ordinary one-shot delegations. The method returns only a detached `ContinuableCreateSpec` (`{ seed? }`) — data, never a capability: it carries no Agent, `AgentHandle`, prompt delivery, result, disposal, or resume operation, because the continuation manager owns identity reservation, composition, Agent creation, prompt delivery, cold resume, ownership, and disposal after preparation. A one-shot `SubagentRun` represents one disposable foreground delegation with one result and no cold-resume operation. The service may invoke one provider concurrently for distinct siblings: each start or preparation owns its mutable state and cancellation path, and one operation's failure, result, or cleanup must not settle or release another. A provider may queue its own capacity internally without changing that independence contract.
+Read these pages when the package-level contract is not enough. They move from the shared seam to the backends, the model-facing tools, and the design decisions.
 
-## The durable descriptor
+- [Subagent subsystem](../../../docs/subsystems/subagent.md) — the service contract, provider contract, and terminal result semantics.
+- [Subagent capability seam](../../../.agents/notes/implemented/feature/2026-06-21-subagent-capability-seam.md) — the design record for the delegation capability family.
+- [Continuable background subagents](../../../.agents/notes/implemented/feature/2026-07-21-continuable-background-subagents.md) — durable children that accept follow-up turns.
+- [In-process spawn backend](../subagent-spawn-in-process/README.md) — the simplest provider to compose.
+- [Out-of-process ACP backend](../subagent-acp/README.md) — children with their own runtime over the Agent Client Protocol.
+- [Merged subagent control service](../../../.agents/notes/implemented/simplification/2026-07-26-merge-subagent-control-service.md) — the follow-up, interrupt, and listing surface.
 
-The Service Definition owns the versioned `subagent/descriptor` session event vocabulary (`src/descriptor.ts`): `snapshotSubagentDescriptor()` validates and detaches the record before provider work, and `foldSubagentDescriptor()` validates the complete current-version payload before recovering it from a loaded child log. Every local session-backed start appends one descriptor with the provider name and lifecycle `mode`. A `one-shot` descriptor optionally carries the caller-owned durable display `label`; a `continuable` descriptor requires its durable creation label and additionally records resolved child `agentOptions.provider`/`model`/`reasoningEffort` and optional `persona`/`toolFilter` for cold resume. These are explicit fields, never the merge-extensible `AgentOptions` object, so an unrelated extension value cannot break continuation. The descriptor omits `subagentDepth` (the persisted header's `delegationDepth` is the monotone floor) and `outputSchema` (an Activation's result contract). The event is log-only: no `surfaceOp`, absent from model history, and retained by the append-only log across compaction. Malformed current-version payloads are corrupt; unsupported versions cannot be classified by this runtime.
-
-## Delegation depth
-
-The seam owns the depth vocabulary shared by Service Providers and Consumers: the `AgentOptions.subagentDepth` declaration, `assertSubagentMaxDepth`, and `delegationDepthOf(agent)`. The persisted `SessionHeader.delegationDepth` is authoritative and monotone — runtime options may deepen the count but never lower it, so a resumed child cannot be re-counted as top-level.
-
-`inheritsParentContext` is descriptive rather than enforceable. It says only whether the child sees completed parent conversation history (`fork` does; `spawn` and the out-of-process one-shot providers do not), not whether it inherits tools, services, or authority.
-
-## Delegated policy
-
-Both in-process delegation paths fix the child's permission scope at the delegation boundary through the shared child-agent helpers. `captureDelegatedPolicyOverrides(parent)` snapshots the parent session's explicit sandbox override (`sandboxPolicy.overrideOf()`) and pins the child's approval policy to `'never'` whenever the approval capability is composed — regardless of the parent's own policy — so a delegated child acts only within its inherited sandbox scope and every ask (for example a `sandbox_permissions` escalation) is rejected deterministically instead of waiting on a prompt no one is watching (both services are optional `ctx.get` consumers). `appendDelegatedPolicyOverrides()` writes each value onto the child's own log as a `source: 'delegation'` `sandbox/mode` or `approval/policy` event during unpublished setup, after any fork seed — so fresh policy wins stale seed state and the child's effective policy stays reconstructable from its log alone. The sandbox deployment default is never copied: an unswitched parent stamps no `sandbox/mode` and its child follows the deployment default dynamically. A continuable start captures before its first await and seeds only fresh materialization; a cold resume replays the persisted delegation events instead of re-capturing the parent, so a parent switch after creation never retroactively changes a durable child. Every in-process child also receives a scoped runtime-context statement (`subagent:delegation`) telling it the scope is fixed and that a task needing wider access ends with a reported limitation, not retries. See the [one-shot](../../../.agents/notes/implemented/feature/2026-07-25-subagent-policy-inheritance.md) and [continuable](../../../.agents/notes/implemented/feature/2026-08-10-continuable-subagent-policy-inheritance.md) delegation-policy Agent Notes.
-
-## One-shot ownership and lifecycle
-
-`provider.start(request): Promise<SubagentRun>` is the ownership-transfer boundary; the delegation tool also uses it inside its one-shot Task-backed background path. Before fulfillment, the provider owns setup and must cancel, roll back, and quiesce unpublished resources on every failure. After fulfillment, the caller owns the run and must call `dispose()` on every path; remaining prompt and turn work belongs to `SubagentRun.result`.
-
-`SubagentRun.result` resolves to `{ output, structured?, diagnostic?, stopReason }`. Child-level failures resolve with a non-`completed` reason; only an infrastructure fault that the seam cannot represent may reject. A provider may add a safe `diagnostic` to a non-completed result after removing tool inputs, file contents, environment values, credentials, and raw protocol payloads and limiting the complete text to 4096 UTF-8 bytes. The common result type does not define provider categories or lifecycle stages: an out-of-process provider may derive fixed display text from its version-pinned structured product facts and an observed process outcome, while consumers render that text without parsing it. The field is not assistant output: consumers present it separately, and it does not enter `subagent/end.lastAssistantMessage`. `dispose()` is idempotent, cancels remaining work, and waits for both result settlement and child-resource quiescence. A result rejection remains on `result`; `dispose()` rejects only for an independent resource-release failure. `output` and the `subagent/end` event's `lastAssistantMessage` use the exported `AssistantOutputFold`/`finalAssistantOutput` helpers to select the child's last non-empty assistant message, or its accumulated assistant text when no such message exists. `output` is `[]` and the event field is absent when the child produced neither ([`SubagentResult`](../../../docs/subsystems/subagent.md#the-terminal-result-subagentresult) owns the terminal result contract).
-
-A local run publishes an ordinary child agent/session before `start()` fulfills, returns that shared session id as `SubagentRun.id`, exposes the exact child as `SubagentRun.localAgent`, records `request.parent.session.id` in the child's `parentSession` header, and appends the resolved descriptor inside its initial turn. Remote providers instead mint a parent-scoped lifecycle id and return `localAgent: undefined`; without a local child session, their one-shot runs are not part of trace-backed enumeration.
-
-## Continuable children and Activations
-
-A continuable child has one durable Session and at most one process-local **Activation** — one residency epoch for a reconstructed child Agent, not a request, result, cancellation, or Task boundary. The Agent inbox is the only turn queue, so the continuation manager owns residency while the Agent loop owns all turn ordering and execution. No continuable path creates a Task or an intermediate result-bearing wrapper.
-
-The manager derives three internal residency conditions from Agent quiescence and the owned-child set rather than maintaining a second state machine: running (an active admission, open turn, or waking inbox work), waiting (quiescent but still owning at least one undisposed child), and settled (quiescent with every owned child disposed, so the manager disposes the `AgentHandle` and removes the Activation). Every continuation message uses `Agent.followup()` and becomes one FIFO turn with no steering of the current turn. Routing depends only on residency: running enqueues, waiting wakes the same Agent, and an absent Activation cold-resumes a new one.
-
-The manager reserves the child identity, resolves the durable descriptor, calls `ctx.agents.create()` (or `ctx.agents.resume()` for cold resume) through a private activation-owner scope, installs the returned `AgentHandle` in the Activation, establishes any continuable-parent ownership, and then submits the prompt. Cold resume never dispatches through a provider because the persisted Session already holds the initial prefix and the folded descriptor is the whole reconstruction input.
-
-### Settlement delivery
-
-When a resident Activation settles, the manager tells the child's durable direct parent, in the parent's own turn stream, that the child produced everything it is going to. Delivery is unconditional for every child whose id a caller actually received: it does not consider whether the child called `report`, because the endings that most need an account — a token ceiling, a model failure, cancellation, teardown — are exactly the ones where the child never got to choose. A materialization rolled back before its first accepted message stays silent, since that caller was told the child was not established. The message carries the epoch's stop reason, its final assistant content when it produced any, and durable provenance `{ kind: 'subagent-settled', form: 'notice', senderSessionId: <child-id> }` — a different source kind from a child-authored `subagent-report`, so a transcript never credits the child with words the runtime wrote.
-
-Two ordering rules make the delivery reliable rather than lucky, and both are why this belongs to the manager instead of an external `subagent/end` listener. First, the send happens **before** the child's ownership release, while the parent still counts the child and is therefore structurally unable to be judged settled. Second, a parent that is itself a resident Activation receives the message through the same waking-admission accounting as a report, so the window between the synchronous send and the microtask that admits it is not mistaken for quiescence — `Agent.status` folds context maintenance into `idle`, and a waking send behind maintenance only arms a deferred wake. Without either rule the parent can be disposed with the notice still in an inbox that `cancel()` clears, which loses it silently.
-
-An idle parent receives the notice as one ordinary later turn. A busy parent is steered into its nearest step boundary instead, so several children settling together cost one step rather than one turn each; steering rather than injecting also means a driver that retires between the status read and the send still claims the message. A parent whose own lineage is already draining receives the notice by injection, with no wake at all: `Agent.followup()` on a quiescent parent starts a turn and `cancel()` does not arm against a later one, so waking during teardown would spend a model request on an Agent its host is about to dispose — once per tree layer, since each layer's notice then wakes the layer above it. The injected message reaches a parent that is still reading its inbox, and the log records the account either way, but it does not outlive that parent's own disposal: `AgentHandle.dispose()` is a `keepInbox: false` cancel, which durably cancels an unclaimed notice. A resumed parent therefore has no pending notice to read: `list_agents` tells it which children exist and whether each is live or stored, while the outcome itself stays in the child's own Session, which a `send_message` reaches by resuming that child. A parent that has left the registry is not an error: the notice is dropped and the child's own Session remains the durable record. Delivery never blocks or fails teardown — a rejected send is logged, because retaining a child to retry a notice would pin its whole ancestry in `waiting` forever.
-
-A continuation-managed parent Activation records each child Session id in an `ownedChildren` set before the child can run and disposes only after every owned child Activation completes `AgentHandle` disposal (child-first). Teardown propagates Agent cancellation top-down before awaiting slow descendants, while handle release remains child-first. Top-level and other non-continuation Agents have no Activation and stay outside this waiting graph. Final settlement awaits a best-effort `ctx.sessions.flush(child.session)` before handle disposal. A listener rejection is logged without failing the Activation because listener participation does not identify a persistence backend; the persisted state may therefore be missing or stale on resume.
-
-## Lifecycle events
-
-The service emits a `subagent/start`/`subagent/end` pair for each one-shot run and each resident continuable Activation epoch, so continuable children are observable with the same vocabulary as one-shot runs without exposing whether the manager materialized, woke, or cold-resumed them. For a one-shot start it attaches the result observer before the synchronous `subagent/start`, so even an already-settled child still produces `subagent/start` before `subagent/end`; a continuable epoch that fails before residency emits neither edge. The pair shares a service-minted `runId`; the `local` flag is snapshotted from the provider's exact `localAgent` (always true for a continuable child), so observers never infer run identity or locality from reusable provider/session names. The `provider` field contains the provider name recorded when the child was first created rather than claiming current registration: an accepted one-shot run may settle after provider removal, and a cold-resumed epoch reads the initial provider name from its descriptor without calling or registering that provider.
-
-Run events are scoped to the delegating parent. Every listener is independently contained: a synchronous throw or rejected returned promise is logged without starving peer listeners or changing the run.
-
-Provider additions and removals also emit `subagent/provider-added` and `subagent/provider-removed`. Consumers such as the model-facing tool use those events because Cordis may load sibling plugins concurrently; configuration order does not prove registration order.
-
-Continuable children do not create `SubagentRun` or Jobs. The continuation manager directly owns one process-local Activation and retained `AgentHandle` per resident child Session, uses the Agent inbox as the only FIFO, and cold-resumes from the durable descriptor. Exact live direct-parent identity authorizes parent-to-child delivery. Exact live child identity authorizes reports; the manager derives the recipient from durable `parentSession`, and `MessageSource` records the sender without granting authority. Interrupt authority is deliberately wider than delivery authority: a human presents the durable direct-parent address so a live child stays stoppable while its parent Agent is offline, and any exact live ancestor recorded in the Activation's materialization lineage may stop its descendant, because stopping a turn is idempotent and delivers no content.
-
-When `ctx.sessionProjections` is available, the service registers two projection units. `subagentTiming` resets at each descriptor so a fork seed's ancestor work cannot enter the child's total, then accumulates `turn/start` → `turn/end` active time and retains same-cut `active.since` and `active.through` bounds for an open turn; while that turn remains open, `active.through` follows the latest folded event, giving an inactive consumer a conservative crash bound without mixing in newer session metadata. `subagent` folds the durable identity — mode plus creation label — from `subagent/descriptor` events with the same last-wins reset discipline, so a fork seed's ancestor descriptor stands only until the child's own overrides it; a malformed or unrecognized-version payload folds to the serializable `null` sentinel — indistinguishable from a log with no descriptor, and surviving every JSON push frame so a consumer replaces a stale identity instead of keeping it — and never throws.
-
-`registerContinuableSetup()` lets optional packages add child-scoped capabilities without teaching the continuation manager their names. Contributions install synchronously before Activation publication, roll back with failed setup, and are released with the child scope. New grants wait for the next Activation, while contribution removal revokes every resident installation immediately.
-
-## Collection model
-
-The model-facing tool collects synchronously by default: it awaits the child result and disposes the run before returning. One-shot background delegation registers a plain Task in the tool, whose generic status, collection, and cancellation tools own later interaction, and persists its model-supplied `description` as the optional display label. Continuable background delegation calls `ctx.subagents.startContinuable()` and returns only the durable child id; the child owns its own turns from inbox acceptance, so there is no Task and no result promise — a caller sends later work with the `send_message` follow-up tool, and `interrupt()` stops only the current turn without disposing the child, and the durable child Session remains the source of the child's detailed output. The continuation manager exists only while `ctx.agents` is available, and session persistence is resolved per continuation operation. Independently, `listChildren()` enumerates the live-preferred merge of the live session store and optional session persistence — live-only when persistence is absent, since a cold child cannot be resumed then either — and serves each child's durable mode/label from the registered `subagent` projection unit: the registry's watermark snapshot for a live child; for a cold one, a durable projection-cache row when it serves an own-suffix identity — its `seq` gate proves the value postdates the fork seed, where a child's own descriptor is immutable once appended — else one bounded-concurrency persistence inspection folded through the registry, whose result must still name the enumerated lifecycle (a re-published id degrades to a `corrupt` diagnostic). A throwing cache read renders no verdict — the cache is derived data — and silently falls through to that authoritative re-fold. The projection fold is the single classification authority; listing parses no descriptor itself. A served identity produces a child row; a settled candidate whose fold served no identity is a `corrupt` diagnostic, a failed inspection is a transient `unavailable` retried on the next listing, and a running candidate without an identity yet is omitted (the creation window before its descriptor is appended). It never consults the continuation manager, Agent registrations, Activations, or providers. Each child row derives its read-time `hasChildren` hint from merged headers carrying durable `origin: 'subagent'`; it does not read descendant event logs, and the descriptor-backed child catalog remains authoritative when expanded. Service consumers such as a UI can retain both modes and choose a fallback for an unlabeled one-shot child; the model-facing `list_agents` tool projects only `continuable` entries and refines status through the live Agent registry and maps storage-only to its resumable-not-terminal `ready` (`running`/`idle`/`ready`) and walks `listDescendants()` for its `descendants` scope. The listing forwards the caller's signal to every persistence read, checks cancellation around each of those awaits, and reports every observed abort as `SubagentError` code `CANCELLED`; an unmounted projection registry fails loud with `SUBAGENT_CONTROL_PROJECTIONS_UNAVAILABLE`, and a missing session store with `SUBAGENT_CONTROL_SESSION_STORE_UNAVAILABLE`. See the [background subagent tasks Agent Note](../../../.agents/notes/implemented/feature/2026-07-08-background-subagent-tasks.md), the [continuable background subagents Agent Note](../../../.agents/notes/implemented/feature/2026-07-21-continuable-background-subagents.md), the [durable catalog Agent Note](../../../.agents/notes/implemented/feature/2026-07-22-durable-subagent-catalog-and-list-agents.md), the [merged-service Agent Note](../../../.agents/notes/implemented/simplification/2026-07-26-merge-subagent-control-service.md), the [capability-seam Agent Note](../../../.agents/notes/implemented/feature/2026-06-21-subagent-capability-seam.md), and `src/types.ts` for the complete contracts.
-
-Continuable Activations await a best-effort final session flush without treating listener participation as durability confirmation. One-shot runs retain best-effort session checkpointing, so a completed one-shot child is discoverable after disposal only when its session actually reached persistence; the service does not invent a catalog entry from Task history when that checkpoint is absent.

 ## Known Limitations and Deferred Work
 
-- **ACP children remain one-shot and are not trace-enumerable** — an ACP run has no local child session in the parent's session corpus. An ACP `prepareContinuable` requires persisting the remote session id in provider-specific descriptor data and a per-child continuation advertisement, since ACP `loadSession` support is negotiated per child rather than established by the method's presence. Remote providers also require a separate Activation ownership contract with equivalent authenticated control and child-first quiescence before they support continuable children.
-- **No host-user continuation** — `followup()` requires the exact live direct parent. Only `interrupt()` accepts a durable parent-address user authority, because stopping a turn is idempotent and delivers no content; a future host adapter needs a concrete authenticated interaction before the seam gains a user delivery capability.
-- **Continuation messages never steer** — parent-to-child continuation messages enqueue later child turns. Child-to-parent reports are independent next-step input and may extend the parent's open turn.
-- **Wake gap during cancellation convergence** — a waking follow-up accepted after the interrupt signal is issued but before the active driver becomes idle remains queued until another waking send. Issue #1838 owns the agent-loop wake latch, which also affects ordinary session cancellation.
-- **Process-local residency** — the Activation inbox and ownership graph do not coordinate two harness processes; concurrent access to one persistence store still requires a durable mailbox and cross-process lease protocol.
-- **No replay of accepted-but-unlogged messages** — only messages written to the child Session log are reconstructable with the source that supplied them. A crash may lose an accepted initial prompt or follow-up that never reached the log; a later authorized message can cold-resume the child, but the lost message is not replayed automatically.
-- **No durable report mailbox** — reports require a live direct parent and provide acceptance identity rather than exactly-once delivery or a read receipt.

-subagent seam 允许一个 agent（智能体）通过具名提供方把工作委派给子 agent。调用方统一使用 `ctx.subagents` 服务 API；提供方决定子 agent 在当前进程、其他进程，还是通过未来的传输方式运行。
+## 概述
 
-[subagent 家族概述](../README.zh.md)列出了实现和面向模型的消费方。本包负责提供方注册表、共享请求和结果约定、持久描述符以及可继续子级编排。多个具名提供方可以在该约定背后共存。
+`dsh-subagent` 是子 agent 委派背后的服务：agent（智能体）把任务交给具名子 agent，收集完成的结果，并且——对可继续子 agent 而言——跨轮次持续发送后续工作。多个提供方在同一约定下共存，因此单个组合可以并排提供进程内子 agent、进程外 ACP 或 SDK 子 agent，以及真实 Codex 或 Claude Code 子 agent。子 agent 有两种形态：一次性运行以单个结果结算，可继续子 agent 的持久会话则接受后续消息并可被中断。同一服务还回答发现类问题——存在哪些子级、它们的模式、活动状态与血缘——而不加载或恢复它们。把它与至少一个提供方后端和一个委派工具一起挂载；后端与面向模型的工具位于兄弟包中。

+## 使用本包
+
+本包是每个委派组合都共享的约定。你通过把服务与一个或多个提供方后端以及面向模型的委派工具一起挂载来启用它；此后 agent 即可委派工作，服务会把每个请求路由到具名提供方。
+
+### 启用委派
+
+把服务与一个提供方和委派工具一起挂载。提供方以你配置的名称注册（进程内 spawn 后端默认为 `spawn`）；工具行指名该提供方，让模型看到一个静态工具。一个最小的一次性配置：
+
+```yaml
+- name: '@deepseek-ai/dsh-subagent'
+- name: '@deepseek-ai/dsh-subagent-spawn-in-process'
+- name: '@deepseek-ai/dsh-tool-subagent'
+  config:
+    provider: spawn
+    toolName: subagent
+```
+
+调用该工具的 agent 会把子 agent 的最终答案作为工具结果收到。只挂载服务本身不会改变任何行为：在组合出提供方和工具之前，什么都不能委派。
+
+### 一次性与可继续子级
+
+一次性子 agent 只运行一次，并以单个结果结算，可附带可选的结构化输出与失败时的安全诊断。启动请求可以通过 `agentOptions` 覆盖子 Agent 的提供方、模型、推理等级与输出 token 上限；每个请求的选项都要求提供方声明对应能力。可继续子 agent 保留持久会话并按顺序接受后续消息：调用方收到稳定的子 agent id、发送后续消息，并可中断当前轮次而不销毁子 agent。工具行的 `backgroundMode` 选择形态（默认 `one-shot`，或在支持的提供方上使用 `continuable`）。
+
+### 后续消息、中断与发现
+
+可继续子 agent 把后续消息作为下一个轮次回答，父级随时可以中断运行中的轮次或列举自己的子级。发现覆盖两种形态：服务列举直接子级与完整后代树——模式、活动状态与血缘——直接读取在线会话状态与可选持久化，不加载任何子 agent。
+
+### 失败与恢复
+
+需要所选提供方不具备的能力的请求会在启动时响亮失败，而不会被静默忽略。失败的子 agent 运行会返回停止原因，提供方后端还会附加安全诊断；被取消的请求以 `aborted` 结算。子 agent 相互隔离：崩溃或行为异常的子 agent 无法破坏父级会话。

+
+本节解释服务的构建方式以及可观察行为从何而来；完整约定见[使用本包](#use-this-package)。
+
+### 设计理念
+
+- **一个服务，多个提供方。** 服务是具名提供方注册表；每个后端以唯一名称注册，请求按名称选择一个。
+- **两种子级形态。** 一次性运行在发布时转移所有权；可继续子级保留持久 Session，且同一时刻至多一个进程内 Activation。
+- **兑现即发布。** 提供方的 `start()` 只有在真实子 agent 存在后才兑现，因此调用方要么拥有一段在线运行，要么一无所有。
+- **同进程值可信。** 请求、描述符与结果按不可变约定借用；序列化与不可信输入校验属于进程与协议边界。

+
+| 文件 | 职责 |
 |---|---|
-| `registerProvider(provider)` | 按名称注册一个可信的同进程实现。注册受 effect 作用域约束；移除注册会阻止新的启动，但不会撤销已返回给调用方的运行。重复名称会明确报错。 |
-| `getProvider(name)` | 返回提供方；不存在时返回 `undefined`。 |
-| `list()` | 按插入顺序返回提供方名称。 |
-| `start(name, request)` | 校验普通调用方请求，解析其已分离的 `one-shot` 描述符，然后等待提供方发布真正的一次性子 agent。兑现时返回由持有方拥有的 `SubagentRun`；如果调用被拒绝，提供方已经清理所有尚未发布的启动资源。发布后的轮次故障或基础设施故障则通过该 run 结算。可继续子 agent 绝不通过此操作进入。 |
-| `startContinuable(spec)` | 建立一个持久化的可继续子 agent，并投递其初始提示词。子 agent 的 inbox 一接受该提示词，调用就会兑现为 `{ childId, messageId }`，无需等待轮次开始，也无需等待消息写入会话日志。在此之前发生的任何失败都会使调用被拒绝，不返回任何 id，并完全回滚该子 agent。如果在线注册表或已配置的持久化已经占用调用方预留的 `childId`，则拒绝该身份。要求 `ctx.agents`、会话持久化以及具备 `prepareContinuable` 能力的提供方。 |
-| `followup(parent, childId, content, { source, signal })` | 将来自确切在线直接父级的一条后续消息作为子 agent 的下一个 FIFO 轮次投递，术语与 `Agent.followup()` 一致，并返回被接受的 `MessageId`。驻留中的子 agent 由其 inbox 直接接受（唤醒处于 waiting 的 Activation）；不驻留的则从其持久化会话冷恢复。要求 `ctx.agents`；冷恢复还要求会话持久化。 |
-| `interrupt(targetSessionId, authority)` | 凭人类出示的持久化父级地址 `{ kind: 'user', parentSessionId }`，或确切在线的祖先 Agent `{ kind: 'ancestor', agent }` 进行授权，中断一个在线可继续子级的当前轮次。准入判定同步完成，但取消异步生效：该操作发出 `Agent.cancel(cause, { keepInbox: true })` 后立即返回，不等待目标观察到信号。尚未领取的待处理 inbox 工作、Activation 和已发布的后代均会保留；已经领取到被中断轮次中的工作不会重新入队。目标不存在时视为已接受的空操作；错误的父级地址，或陈旧、指向自身、并非祖先的调用方，会以 `UNAUTHORIZED` 被拒绝。 |
-| `reportFrom(child, content, { delivery, signal })` | 从确切在线可继续 child 向其确切在线直接 parent 投递一条选中消息，并返回已接受的稳定 `MessageId`。静默投递会注入不唤醒的 next-step 上下文；next-step 投递会 steering 并唤醒 parent。 |
-| `registerContinuableSetup(contribution)` | 把一项可选部署能力组合到每个可继续 child 尚未发布的作用域中，并支持从驻留 child 立即撤销。 |
-| `drainContinuableDescendants(parents)` | 在由 host 拥有的确切在线父级 Agent 之下关闭准入，只停止这些父级可见的可继续后代；等待已在这些根节点下获准的物化过程完成发布或回滚后，再按子级优先顺序释放所选的各棵树。该截止状态会持续到每个确切父级离开注册表；无关的父级树仍在线，管理器全局准入仍保持开放。 |
-| `drainContinuableChildren(parent, childIds)` | 只释放一个确切在线父级的具名驻留可继续直接子级，并递归保持子级优先顺序。它不关闭准入、不影响同级子级，缺失的 id 视为空操作；若驻留子级属于其他父级，则拒绝。这是拆卸操作，因此与 `interrupt()` 不同，它不会保留待处理的 inbox 工作。 |
-| `listChildren(parentSessionId, signal?)` | 按 `createdAt`、再按 id 的顺序列出由会话支撑的直接 subagent，包括其 `one-shot`／`continuable` 模式、`running`／`inactive` 活动状态、根据 origin 分类得出的一层 `hasChildren` 提示，以及每个子级的诊断信息，且不会加载或恢复它们。该操作直接读取在线会话存储和可选的会话持久化（没有持久化时只枚举在线子级），并要求已挂载 `sessionProjections` 注册表；不要求 `ctx.agents`、继续执行管理器或任何查询服务。 |
-| `listDescendants(rootSessionId, signal?)` | 从同一份在线优先语料按稳定 pre-order 展平根的完整会话树，并为每个 subagent 条目附加持久 `parentId` 与相对根的 `depth`。普通会话与一次性 child 仍作为遍历节点，因此其下的可继续后代仍可发现。身份、diagnostic、依赖与取消约定均沿用 `listChildren()`。 |
+| [`src/index.ts`](src/index.ts) | 服务入口：提供方注册表、启动与继续 API、生命周期事件 |
+| [`src/continuation.ts`](src/continuation.ts) | 可继续子级：身份预留、Activation 驻留、后续消息、中断、结算 |
+| [`src/types.ts`](src/types.ts) | 公开的请求、结果与提供方约定 |
+| [`src/descriptor.ts`](src/descriptor.ts) | 版本化的 `subagent/descriptor` 会话事件词汇 |
+| [`src/child-agent.ts`](src/child-agent.ts) | 子级组装、委派策略、深度辅助函数 |
+| [`src/list-children.ts`](src/list-children.ts) | 基于在线会话存储与可选持久化的发现 |
 
-`SubagentStartRequest.label` 是由会话支撑的一次性 child 所使用的可选简短持久化显示标签。面向模型的委派会提供其已有的 `description`；底层调用方无需凭空构造展示元数据。可继续启动始终携带自身的必填标签。`signal` 是必填项，也是一次性 `start` 的规范取消通道。发布前中止会使 `start()` 在回滚后拒绝；发布后中止会取消已返回 run 的剩余轮次工作，但不会隐藏其 id。请求还可以覆盖宿主 Agent 的提供方、模型、推理强度与 token 上限、要求结构化输出、限制委派深度、约束子 agent 工具或设置子 agent persona。每个被请求的可选特性都要求匹配的提供方能力。对于可继续启动或后续操作，调用方信号只负责 inbox 接受前的查找、物化和准入；此后，Activation 由管理器独立拥有，因此调用方取消既不会取消已接受的轮次，也不会 dispose（资源释放）子 agent。
+### 一次性流程
 
-后续操作的权限来自子 agent 持久化 header 中记录的确切在线直接父级。冷恢复会在重建前检查该权限，并在最终无 await 的 inbox 准入区间再次检查，因此在物化期间被注销或替换的 parent 无法授权投递。后续操作上的 `source` 记录谁提供了所投递的消息，不授予任何权限。
+请求先对照提供方声明的能力进行校验，随后对持久化描述符做快照，再由提供方构建子 agent。两个进程内提供方都声明 `agentOptions`：创建子级时把请求字段叠加到父级最新已记录请求的提供方、模型与推理等级之上；父级还没有请求时回退到创建选项，并保留配置的 token 上限。更改路由而不显式指定推理等级时，会清除继承的路由自有等级，使所选模型解析自己的默认值。DSH SDK 也声明该能力并公开不可变的 `agentRouteDefaults`，使其实例持有的提供方／模型默认值在确切路由预检前成为基线；`start()` 仍负责直接调用方与输出上限。ACP、Codex 与 Claude Code 会拒绝 agent 路由覆盖，而不是静默忽略。成功时运行被发布、所有权转移给调用方；失败时提供方回滚每个尚未发布的资源。结果携带子 agent 的最终输出、可选的结构化值、停止原因与可选的安全诊断。
 
-同进程请求、描述符、结果和事件 payload 都是可信的类型值，并按不可变约定借用。服务不会克隆或冻结它们；序列化和不可信输入校验属于真实的进程、worker、持久化和模型边界。
+### 可继续流程
 
-## 能力
+管理器预留子 agent 身份、解析持久化描述符、创建（或冷恢复）子 agent、把它安装进 Activation 并提交提示词。后续消息经子 agent 自己的 inbox 成为 FIFO 轮次；没有 Activation 时从持久化会话冷恢复。当驻留 Activation 结算时，管理器会在父级自身的轮次流中告知该子级的直接父级。
 
-启动时功能通过 `provider.capabilities` 声明，因为服务必须在创建子 agent 前拒绝不受支持的一次性请求：
+### 所有权与不变式
 
-- `agentOptions`：应用宿主 Agent 提供方、模型、推理强度与输出 token 上限覆盖；
-- `outputSchema`：强制执行结构化最终结果；
-- `depthLimit`：强制执行 `maxDepth`；
-- `toolFilter`：应用请求的子 agent 工具限制；
-- `persona`：应用每个子 agent 独立的 persona。
+- **发布即边界**——发布前提供方拥有设置并须在失败时回滚；发布后调用方拥有运行并须 dispose（资源释放）它。
+- **注册受 effect 作用域约束**——移除提供方会阻止新启动，但绝不撤销已接受的运行。
+- **继续执行权限基于确切身份**——后续消息要求确切在线直接父级；上报要求确切在线子级。
+- **描述符仅进日志**——它是会话事件，不进入模型历史，并跨压缩（compaction）保留；可继续描述符会显式记录解析后的子级提供方、模型与推理等级，用于冷恢复。
 
-两个进程内提供方都会声明 `agentOptions`：创建子 agent 时，请求字段会覆盖父级最新记录请求中的提供方、模型与推理强度；首个请求之前回退到其创建选项，并保留其中配置的 token 上限。更换路由但没有显式指定强度时，会清除继承的路由所属强度，使所选模型解析自己的默认值。DSH SDK 也声明该能力，并公开不可变的 `agentRouteDefaults`，使其实例持有的 provider／model 默认值在确切路由预检前成为 Consumer 的合并基线；`start()` 仍对直接调用方与输出上限负责。ACP、Codex 与 Claude Code 声明不支持该能力，因此它们的传输会拒绝配置或模型选择的覆盖，而不会静默忽略。
+</details>
 
-每个进程内子 agent 都通过一次 `applyChildComposition(childCtx, parent, composition)` 调用完成组装：先加入父级的 agent-preset 组合，再应用子 agent 自己的 persona 和工具限制。加入父级组合正是子 agent 获得能力的途径：所有面向模型的行都位于 agent 平面，完全没有加入任何组合的子 agent 抵达模型时会看到空的工具注册表（见 [`dsh-agent-presets`](../../preset/agent-presets/README.zh.md)）。将父级作为参数是刻意设计：这让“组装子 agent 却不做该加入”在各调用点无法表达，而这正是这一次调用所要杜绝的缺陷。未组装 preset roster 的部署不加入任何组合、也不需要加入；其面向模型的行位于宿主组合中，子 agent 已能通过工具注册表的全局层解析到它们。
+-----
 
-`childSessionMeta()` 把所加入的 preset id 记在子 agent 的持久化 header 上，理由与顶层会话记录自己的那一个相同：preset 决定了模型所见的工具 schema 与提示段，因此冷读子 agent 的历史时必须重建那份组装，而不是部署默认值。该值从父方**活着的** scope 链读取，而不是从父方 header 读取，因为在空白期切换过 preset 的父方运行在更新的那份组装上，而它的 header 仍写着旧的那个。

-可继续创建对应可选的 `SubagentProvider.prepareContinuable?()` 方法：方法是否存在就是能力检查，因此服务会在没有该方法的提供方上拒绝已配置的可继续启动，而具备该方法的提供方仍可服务普通一次性委派。该方法只返回已分离的 `ContinuableCreateSpec`（`{ seed? }`）。它只是数据，不携带任何能力：不包含 Agent、`AgentHandle`、提示词投递、结果、dispose 或恢复操作。准备完成后，身份预留、组合、Agent 创建、提示词投递、冷恢复、所有权和 dispose 均由继续执行管理器负责。一次性 `SubagentRun` 表示一次可 dispose 的前台委派，只有一个结果，且没有冷恢复操作。服务可以针对不同的同级子 agent 并发调用同一提供方：每次启动或准备都拥有各自的可变状态和取消路径，一项操作的失败、结果或清理不得使另一项操作结算或释放。提供方可以在内部按自身容量排队，但不得改变这项独立性约定。

-该 Service Definition 拥有版本化的 `subagent/descriptor` 会话事件词汇（`src/descriptor.ts`）：`snapshotSubagentDescriptor()` 会在提供方工作之前校验并分离记录，`foldSubagentDescriptor()` 则会在从已加载子 agent 日志中恢复描述符之前，校验当前版本的完整 payload。每次由本地会话支撑的启动都会追加一个带有提供方名称与生命周期 `mode` 的描述符。`one-shot` 描述符可以携带调用方拥有的可选持久化显示 `label`；`continuable` 描述符要求其持久化创建标签，并另外记录已解析的子 agent `agentOptions.provider`／`model`／`reasoningEffort`，以及用于从持久化存储恢复的可选 `persona`／`toolFilter`。这些是显式字段，绝不是可通过合并扩展的 `AgentOptions` 对象，因此无关的扩展值不会破坏继续执行。描述符省略 `subagentDepth`（持久化 header 的 `delegationDepth` 是单调下界）和 `outputSchema`（单次 Activation 的结果约定）。该事件只进入日志：不含 `surfaceOp`，不进入模型历史，并由仅追加日志跨压缩（compaction）保留。格式错误的当前版本 payload 属于损坏；本运行时无法对不受支持的版本进行分类。
-
-## 委派深度
-
-该 seam 拥有 Service Provider 和 Consumer 共享的深度词汇：`AgentOptions.subagentDepth` 声明、`assertSubagentMaxDepth` 和 `delegationDepthOf(agent)`。持久化的 `SessionHeader.delegationDepth` 具有权威性且单调：运行时选项可以增大委派深度，但绝不能将其降到这个下界以下，因此恢复后的子 agent 不会被重新计为顶层。
-
-`inheritsParentContext` 只用于描述，不能强制执行。它仅说明子 agent 是否能看到父级已完成的对话历史（`fork` 可以；`spawn` 和各进程外一次性提供方不可以），不表示是否继承工具、服务或权限。
-
-<a id="delegated-policy"></a>
-
-## 委派策略
-
-两条进程内委派路径都会通过共享的子 agent 辅助函数，在委派边界固定子 agent 的权限范围。`captureDelegatedPolicyOverrides(parent)` 会为父会话的显式沙箱覆盖项（`sandboxPolicy.overrideOf()`）创建快照，并在审批能力已组合时将子 agent 的审批策略固定为 `'never'`，无论父级自身采用何种策略。这样，被委派的子 agent 只能在继承的沙箱范围内行动，每次审批请求（例如 `sandbox_permissions` 升权）都会被确定性拒绝，而不会等待无人处理的提示（这两个服务都是可选的 `ctx.get` 消费方）。`appendDelegatedPolicyOverrides()` 则在未发布的设置阶段、在任何 fork 种子之后，把每个值作为一条 `source: 'delegation'` 的 `sandbox/mode` 或 `approval/policy` 事件写入子 agent 自己的日志。因此，新捕获的策略会覆盖种子中的陈旧状态，而子 agent 的生效策略始终可以仅凭其日志重建。沙箱的部署默认值绝不复制：未切换的父级不会记录 `sandbox/mode`，其子 agent 会动态跟随部署默认值。可继续启动会在第一次 await 前捕获策略，并且只为全新物化写入这些委派事件；冷恢复只会重放已持久化的委派事件，不会重新捕获父级策略，因此创建之后的父级切换绝不会追溯性地改变持久化子 agent。每个进程内子 agent 还会收到一条作用域内的运行时上下文声明（`subagent:delegation`），告知其权限范围已固定，需要更宽访问的任务应以上报限制收尾，而不是重试。参见[一次性](../../../.agents/notes/implemented/feature/2026-07-25-subagent-policy-inheritance.zh.md)与[可继续](../../../.agents/notes/implemented/feature/2026-08-10-continuable-subagent-policy-inheritance.zh.md)两篇委派策略 Agent Note。
-
-## 一次性所有权与生命周期
-
-`provider.start(request): Promise<SubagentRun>` 是所有权转移边界；委派工具也会在其由 Task 支撑的一次性后台路径中使用它。兑现前，提供方拥有设置过程，并且在任何失败路径上都必须取消、回滚并使尚未发布的资源完全停稳。兑现后，run 的所有权转移给调用方；调用方必须在每条路径上调用 `dispose()`。剩余提示词和轮次工作属于 `SubagentRun.result`。
-
-`SubagentRun.result` 兑现为 `{ output, structured?, diagnostic?, stopReason }`。子 agent 级失败会以非 `completed` 原因兑现；只有 seam 无法表示的基础设施故障才可以拒绝。提供方可以为非完成结果附加安全的 `diagnostic`：它会先排除工具输入、文件内容、环境值、凭证与原始协议载荷，并把完整文本限制在 4096 个 UTF-8 字节以内。共享结果类型不定义提供方类别或生命周期阶段：进程外提供方可以从锁定版本产品提供的结构化事实与已观测的进程结果派生固定展示文本，而消费方只负责原样呈现，不解析该文本。该字段不是 assistant 输出；消费方会将它分开呈现，它也不会进入 `subagent/end.lastAssistantMessage`。`dispose()` 是幂等的，会取消剩余工作，并等待结果结算以及子 agent 资源完全停稳。result 的拒绝只通过 `result` 本身报告；只有独立的资源释放失败，才会使 `dispose()` 被拒绝。`output` 与 `subagent/end` 事件的 `lastAssistantMessage` 使用导出的 `AssistantOutputFold`／`finalAssistantOutput` 辅助函数选取子 agent 最后一条非空 assistant 消息；若没有这类消息，则选取其累积的 assistant 文本。子 agent 两种输出均未产生时，`output` 为 `[]`，该事件字段缺省（终态结果约定归 [`SubagentResult`](../../../docs/subsystems/subagent.zh.md#the-terminal-result-subagentresult) 所有）。
-
-本地运行会在 `start()` 兑现前发布普通的子 agent／会话，把该共享会话 id 作为 `SubagentRun.id` 返回，以 `SubagentRun.localAgent` 公开准确的子 agent，把 `request.parent.session.id` 记录到子 agent 的 `parentSession` header，并在其初始轮次内追加已解析的描述符。远程提供方则生成 parent 作用域的生命周期 id，并返回 `localAgent: undefined`；由于没有本地 child 会话，其一次性运行不会进入基于追踪的枚举结果。
-
-## 可继续子 agent 与 Activation
-
-每个可继续子 agent 都有一个持久化 Session，并且同一时刻至多有一个进程内 **Activation**。Activation 表示重建后的子 agent 的一次驻留时段，不是请求、结果、取消或 Task 的边界。Agent inbox 是唯一的轮次队列，因此驻留归继续执行管理器，所有轮次排序与执行归 agent loop（智能体循环）。任何可继续路径都不会创建 Task 或中间的承载结果的包装层。
-
-管理器根据 Agent 的完全停稳状态和所拥有的子级集合推导三种内部驻留状态，而不维护第二套状态机：running 表示存在正在进行的准入、尚未结束的轮次，或会唤醒 Agent 的 inbox 工作；waiting 表示 Agent 已完全停稳，但仍拥有至少一个尚未 dispose 的子级；settled 表示 Agent 已完全停稳且所有拥有的子级均已 dispose，此时管理器会 dispose `AgentHandle` 并移除 Activation。每条后续消息都使用 `Agent.followup()` 并成为一个 FIFO 轮次，且不会对当前轮次进行 steering（中途引导）。路由只取决于驻留状态：running 入队、waiting 唤醒同一 Agent，无 Activation 时则冷恢复一个新的。
-
-管理器预留子 agent 身份、解析持久化描述符，通过私有的 activation-owner 作用域调用 `ctx.agents.create()`（冷恢复时为 `ctx.agents.resume()`），把返回的 `AgentHandle` 安装到 Activation 中，建立任何可继续父级所有权，然后提交提示词。冷恢复绝不通过提供方分发，因为持久化会话已持有初始前缀，折叠后的描述符即是全部重建输入。
-
-### 结算投递
-
-当一个驻留 Activation 结算时，管理器会在父级自身的轮次流中告知该子级持久化的直接父级：这个子级已经产出它将产出的全部内容。对于每个已经向调用方返回过 id 的子级，管理器都会无条件投递结算通知，不考虑该子级是否调用过 `report`。最需要说明结局的终止情形，包括达到 token 上限、模型失败、取消或拆卸，恰恰是子级根本没有机会选择的那些情形。在第一条消息被接受之前就回滚的物化保持静默，因为那位调用方已被告知该子级未建立。消息会携带该 epoch 的终止原因、它产出过的最终 assistant 内容，以及持久化来源 `{ kind: 'subagent-settled', form: 'notice', senderSessionId: <child-id> }`——与子级自撰的 `subagent-report` 是不同的来源 kind，因此 transcript（文本记录）绝不会把运行时写下的话算到子级头上。
-
-有两条顺序规则让这条投递可靠而非侥幸，它们也正是这件事属于管理器而非外部 `subagent/end` listener 的原因。第一，发送发生在子级所有权释放**之前**，此时父级仍然计入该子级，因此在结构上不可能被判定为已结算。第二，如果父级本身也是驻留 Activation，该消息会采用与 report 相同的唤醒准入记账。这样，从同步发送消息到负责准入该消息的 microtask 运行之间的窗口，不会被误判为完全停稳——`Agent.status` 会把上下文维护折叠成 `idle`，而维护期间的唤醒发送只会预置一次延后唤醒。缺少其中任一条规则，父级都可能在通知仍留在 inbox 时被 dispose，而 `cancel()` 会清空该 inbox，于是通知被静默丢失。
-
-空闲父级会以一个普通的后续轮次收到该通知。繁忙父级则被 steer 到其最近的 step 边界，因此同时结算的多个子级只消耗一个 step，而不是各自一个轮次；采用 steer 而非 inject 还意味着：即便驱动在状态读取与发送之间退出，该消息仍会被认领。如果父级所在的谱系已经开始排空，该通知会通过 inject 投递，且完全不会唤醒父级。对已经完全停稳的父级调用 `Agent.followup()` 会开启新轮次，而 `cancel()` 不会预先阻止之后开启的轮次；因此在拆卸期间唤醒父级，会让宿主即将 dispose 的 Agent 多执行一次模型请求，而且树的每一层各一次，因为每层自己的通知又会唤醒上一层。被 inject 的消息会送达仍在读取自身 inbox 的父级，而无论如何日志都会记录这份记账；但它不会比该父级自身的 dispose 活得更久：`AgentHandle.dispose()` 是一次 `keepInbox: false` 的 cancel，会持久地取消尚未被认领的通知。因此 resume 后的父级没有待处理通知可读：`list_agents` 只告诉它有哪些子级、各自是在线还是仅存于存储；结局本身留在子级自己的 Session 里，一次 `send_message` 会通过 resume 该子级把它取回。已离开注册表的父级不算错误：通知被丢弃，子级自身的 Session 仍是持久记录。投递绝不会阻塞或使拆卸失败——发送被拒只会记录日志，因为为了重试一条通知而保留子级，会把它的整条祖先链永久钉在 `waiting` 上。
-
-受继续执行管理的父级 Activation 会在子 agent 能够运行之前，把每个子 agent 的会话 id 记录到 `ownedChildren` 集合中，并且只有在每个所拥有的子 agent Activation 完成 `AgentHandle` dispose 之后才会 dispose（子先于父）。拆卸会先自顶向下传播 Agent 取消，再等待缓慢的后代，而 handle 释放仍保持 child-first。顶层及其他非继续执行的 Agent 没有 Activation，处于该等待图之外。最终结算会在 dispose handle 前等待 best-effort 的 `ctx.sessions.flush(child.session)`。监听器拒绝会被记录，但不会使 Activation 失败，因为监听器参与本身不能标识持久化后端；因此恢复时的持久化状态仍可能缺失或陈旧。
-
-## 生命周期事件
-
-服务会为每次一次性运行以及每个已驻留的可继续 Activation 时段发出一对 `subagent/start`/`subagent/end`，因此可继续子 agent 可用与一次性运行相同的词汇观察，且不会暴露管理器是物化、唤醒还是冷恢复了它们。对于一次性启动，它会在同步的 `subagent/start` 之前附加结果观察器，因此即使子 agent 已经结算，也仍会先产生 `subagent/start`，再产生 `subagent/end`；在驻留前失败的可继续时段不会发出这对生命周期事件中的任何一个。这对事件共享由服务生成的 `runId`；`local` 标志根据提供方返回的确切 `localAgent` 是否存在取得快照（可继续子级恒为 true），因此观察器不会根据可复用的提供方名称或会话名称推断运行身份或本地性。`provider` 字段包含子 agent 初次创建时记录的提供方名称，不表示该提供方当前仍在注册：已接受的一次性 run 可在提供方移除后才结算；冷恢复时段会从描述符读取初始提供方名称，不会调用或注册该提供方。
-
-运行事件受执行委派的父级作用域约束。每个监听器都独立隔离：同步抛出或返回的 promise 被拒绝时，只会记录日志，不会阻塞同级监听器或改变运行。
-
-提供方新增和移除还会发出 `subagent/provider-added` 与 `subagent/provider-removed`。面向模型的工具等消费方使用这些事件，因为 Cordis 可能并发加载同级插件；配置顺序不能证明注册顺序。
-
-可继续子级不会创建 `SubagentRun` 或 Task。继续执行管理器为每个驻留子会话直接拥有一个仅存在于当前进程的 Activation 和一个留存的 `AgentHandle`，使用 Agent inbox 作为唯一 FIFO，并从持久化描述符冷恢复。父到子投递由确切在线的直接父级身份授权。上报则由确切在线的子级身份授权；管理器根据持久化的 `parentSession` 推导接收方，`MessageSource` 记录发送方，但不授予权限。中断权限被刻意设计得比投递权限更宽：人类出示持久化直接 parent 地址，因此即使 parent Agent 离线，在线 child 仍可被停止；Activation 物化时记录的任何确切在线 ancestor 也可以停止其后代，因为停止一个轮次是幂等的，且不投递任何内容。
-
-当 `ctx.sessionProjections` 可用时，服务会注册两个投影单元。`subagentTiming` 会在每个描述符处重置，使 fork 种子中的祖先工作不会计入 child 总量，随后累加 `turn/start` → `turn/end` 活跃时间，并为未结束的轮次保留同一切面的 `active.since` 和 `active.through` 边界；在该轮次保持未结束期间，`active.through` 会跟随最近折叠的事件，从而为 inactive 消费方提供保守的崩溃上界，又不会混入更新的会话元数据。`subagent` 以同样的 last-wins 重置纪律从 `subagent/descriptor` 事件折叠持久化身份——模式与创建标签——因此 fork 种子中的祖先描述符只在 child 自身的描述符覆盖之前有效；畸形或版本无法识别的载荷折叠为可序列化的 `null` 哨兵——与没有描述符的日志不可区分，且能完好通过每个 JSON 推送帧，让消费方以之替换掉手中的陈旧身份而非继续保留该身份——绝不抛错。
-
-`registerContinuableSetup()` 允许可选包添加子级作用域能力，而无需让继续执行管理器知道这些能力的名称。贡献会在 Activation 发布前同步安装，在设置失败时一并回滚，并随子级作用域释放。新授权须等到下一个 Activation，移除贡献则会立即撤销每个驻留安装项。
-
-## 收集模型
-
-面向模型的工具默认同步收集：先等待子 agent 结果，再 dispose 运行，然后才返回。一次性后台委派会在工具中注册普通 Task，其通用状态、收集和取消工具负责后续交互，并将模型提供的 `description` 持久化为可选显示标签。可继续后台委派会调用 `ctx.subagents.startContinuable()`，只返回持久化子 agent id；子 agent 自 inbox 接受起就拥有自己的轮次，因此没有 Task、也没有结果 promise——调用方通过 `send_message` 后续操作工具发送后续工作，`interrupt()` 只停止当前轮次而不 dispose 子 agent，而持久化子 agent 会话仍是子 agent 详细输出的来源。只有 `ctx.agents` 可用时，继续执行管理器才会存在，而会话持久化按每项继续执行操作解析。与此独立，`listChildren()` 枚举在线会话存储与可选会话持久化的在线优先合并——持久化缺席时仅枚举在线 child，因为那时冷 child 本就无法恢复——并由已注册的 `subagent` 投影单元供给每个 child 的持久化模式与标签：在线 child 取注册表的水位快照；冷 child 先取可选投影缓存的持久化行，且仅当其 `seq` 门证明该值折叠自 child 自身后缀（fork 种子之后——自有描述符一经追加即不可变）才直接采用，否则经一次有界并发的持久化 inspect 再经注册表折叠，且 inspect 结果必须仍指向枚举时的生命周期（同 id 被重新发布的会话降级为 `corrupt` diagnostic）。缓存读取抛出异常时，不会据此作出分类判断，因为缓存只是派生数据；静默落到该权威重折。分类结果完全以投影折叠为准；列表操作本身不解析描述符。取得身份值即产出 child 行；已定局而折叠未产出身份的候选是 `corrupt` diagnostic，inspect 失败是瞬时的 `unavailable`（下次列表重试），运行中而暂无身份值的候选整行省略（描述符尚未追加的创建窗口）。它不查询继续执行管理器、Agent 注册信息、Activation 或提供方。每个 child 行都会根据合并结果中携带持久化 `origin: 'subagent'` 的 header 派生读取时的 `hasChildren` 提示；它不会读取后代事件日志，展开后仍以描述符支撑的 child 目录为权威依据。UI 等服务消费方可以保留两种模式，并为无标签的一次性 child 选择回退展示；面向模型的 `list_agents` 工具只投影 `continuable` 条目，通过在线 Agent 注册表细化状态，并把仅存于存储的状态映射为可恢复而非终态的 `ready`（`running`／`idle`／`ready`），并在 `descendants` scope 下遍历 `listDescendants()`。列表操作会把调用方的取消信号转发到每次持久化读取，在这些 await 前后检查取消，并将每次检测到的中止报告为 `SubagentError` 错误码 `CANCELLED`；投影注册表未挂载则以 `SUBAGENT_CONTROL_PROJECTIONS_UNAVAILABLE` 响亮失败，会话存储缺失则以 `SUBAGENT_CONTROL_SESSION_STORE_UNAVAILABLE` 响亮失败。完整约定见[后台 subagent 任务 Agent Note](../../../.agents/notes/implemented/feature/2026-07-08-background-subagent-tasks.zh.md)、[可继续后台 subagent Agent Note](../../../.agents/notes/implemented/feature/2026-07-21-continuable-background-subagents.zh.md)、[持久化目录 Agent Note](../../../.agents/notes/implemented/feature/2026-07-22-durable-subagent-catalog-and-list-agents.zh.md)、[服务合并 Agent Note](../../../.agents/notes/implemented/simplification/2026-07-26-merge-subagent-control-service.zh.md)、[能力 seam Agent Note](../../../.agents/notes/implemented/feature/2026-06-21-subagent-capability-seam.zh.md)和 `src/types.ts`。
-
-可继续 Activation 会等待 best-effort 的最终会话 flush，但不会把 listener 参与视为持久性确认。一次性运行保留尽力执行的会话检查点，因此已完成的一次性 child 只有在其会话确实进入持久化存储时，才可在 dispose 后继续被发现；如果该检查点缺失，服务不会根据 Task 历史虚构目录条目。

-- **ACP 子 agent 仍为一次性，且无法通过追踪枚举**：ACP 运行在 parent 会话语料中没有本地 child 会话。ACP 的 `prepareContinuable` 需要在提供方专用描述符数据中持久化远端会话 id，以及逐子 agent 的继续执行能力声明，因为 ACP 的 `loadSession` 支持按子 agent 协商，而不是通过方法是否存在来确定。远程提供方还需要一份独立的 Activation 所有权约定，具备等效的经认证控制和子先于父的完全停稳保证，才能支持可继续子 agent。
-- **无 host-user 继续执行**：`followup()` 要求确切在线直接父级。只有 `interrupt()` 接受持久化 parent 地址形式的用户授权，因为停止一个轮次是幂等的且不投递任何内容；未来 host 适配器需要具体的经认证交互，才能让该 seam 获得用户投递能力。
-- **继续执行消息绝不 steering**：parent 到 child 的继续执行消息会排入后续 child 轮次。child 到 parent 的 report 是独立的 next-step 输入，可能延长 parent 已打开的轮次。
-- **取消收敛期间存在唤醒缺口**：中断信号发出后、活动 driver 进入 idle 前被接受的唤醒型 follow-up 会保持排队，直到另一条唤醒发送到达。Issue #1838 负责 agent-loop 的唤醒锁存；普通会话取消也受此影响。
-- **驻留仅限进程内**：Activation inbox 与所有权图不会在两个 harness 进程之间协调；对单个持久化存储的并发访问仍然需要持久化邮箱和跨进程租约协议。
-- **不回放已接受但未记录的消息**：只有写入子 agent 会话日志的消息才能连同提供该消息的来源一起重建。崩溃可能丢失从未写入日志、已被接受的初始提示词或后续消息；此后一条经授权的消息可以冷恢复该子 agent，但丢失的消息不会自动回放。
-- **没有持久化的上报 mailbox**：上报需要在线直接父级，提供的是接受标识，不保证恰好一次投递，也不提供已读回执。

 # @deepseek-ai/dsh-tool-subagent-control
 
 English | [中文](README.zh.md)
 
-The optional, globally named `send_message`, `interrupt_agent`, and `list_agents` tools are thin adapters over `ctx.subagents`. Provider-bound `@deepseek-ai/dsh-tool-subagent` instances register distinct delegation tools per transport; this separately loaded package registers shared control tools once, so multiple delegation tools never register duplicate global controls. The root plugin registers `send_message` and `interrupt_agent` and requires only `subagents`; the separately loadable `./list-agents` plugin registers `list_agents` and declares `subagents` plus `agents` as load-time dependencies. Its catalog reads additionally require the session store and projection registry at call time, but no query service. A deployment can keep the root tools while omitting the list tool. No tool's presence determines whether a delegation tool starts continuable work. These tools own only the parent-to-child direction; the independently installed [`@deepseek-ai/dsh-tool-subagent-report`](../tool-subagent-report/README.md) owns the child-to-parent direction.
+## Summary
 
-The tool performs no lifecycle routing — residency and cold resume belong to the subagent service. It passes `exec.agent` as the exact live parent that authorizes delivery and records every message source as `{ kind: 'coordinator', senderSessionId: parent.id }`, which the service retains but never treats as authority. Every message becomes the subagent's next FIFO turn through `Agent.followup()`: if the child is still working, the message waits until its current turn finishes, so it cannot redirect work already underway. The tool forwards its execution signal, which owns admission only until inbox acceptance; once the child accepts the message the accepted turn cannot be cancelled through this tool. This call returns no child reply — its transcript by that id is the source of what it did — and a child with `report` sends content on its own initiative as a separate parent message. A delivery failure becomes an errored tool result stating the message was not delivered.
+`dsh-tool-subagent-control` adds the global control tools for continuable children: `send_message` delivers a follow-up message that becomes the child's next turn, `interrupt_agent` stops a child's current turn while keeping its queue and descendants intact, and `list_agents` (from the separately loadable `list-agents` plugin) lists continuable children by durable id and label. The tools are global, so any number of delegation tools never duplicates them. These tools cover only the parent-to-child direction; the child-to-parent direction belongs to the independently installed `dsh-tool-subagent-report`. No tool's presence decides whether a delegation tool starts continuable work.
 
-`interrupt_agent(agent_id)` passes `exec.agent` as the exact live ancestor authority for `ctx.subagents.interrupt()`: the target may be a direct child or a deeper descendant, and the service — never this tool — verifies the caller against the target Activation's recorded lineage. Only the target's current turn stops (`keepInbox`): queued messages stay parked until a later `send_message`, published descendants keep running, and the child stays available for follow-ups. The call returns as soon as the stop request is accepted, without waiting for target quiescence; an absent or already-settled target is an accepted no-op, while self, sibling, stale, and non-ancestor callers become errored results.
+## Table of Contents
 
-`list_agents` takes one optional `scope` argument, derives the root id from the calling agent, and projects the service catalog to continuable children without a cursor. The default `children` scope reads `ctx.subagents.listChildren()`; `descendants` reads `ctx.subagents.listDescendants()`, whose one-corpus walk crosses ordinary sessions and one-shot children and renders surviving rows in stable pre-order with `parent=<id> depth=<n>`. The `parent` annotation is the durable direct-parent session id and may name an ordinary session omitted from the output. For the calling agent, only depth-1 child entries are `send_message` candidates; deeper child entries are `interrupt_agent` candidates only. Status comes from the live Agent registry: `running` (active driver), `idle` (resident between turns, possibly waiting on agents it started), or `ready` (storage only and resumable rather than terminal). The service result also contains one-shot session-backed subagents for consumers such as a UI, but those entries are omitted from this model tool because they cannot accept `send_message`. Diagnostics remain visible, with positions in the descendants scope. Durable identity and mode come from each child's descriptor, while delivery-time authority and Activation ownership checks remain the service's.

+## Use this package
+
+Mount this package in any composition with continuable children the model should message, interrupt, or list. The root plugin needs only the subagent service; the list tool is a separate plugin a deployment can omit.
+
+### Minimal configuration
+
+Load the subagent service, a backend, the delegation tool, and this package. Adding the separate list plugin exposes all three tools:
+
+```yaml
+- name: '@deepseek-ai/dsh-subagent'
+- name: '@deepseek-ai/dsh-subagent-spawn-in-process'
+- name: '@deepseek-ai/dsh-tool-subagent'
+  config:
+    provider: spawn
+    backgroundMode: continuable
+- name: '@deepseek-ai/dsh-tool-subagent-control'
+- name: '@deepseek-ai/dsh-tool-subagent-control/list-agents'
+```
+
+This package takes no configuration: the root plugin provides `send_message` and `interrupt_agent`, and the list plugin provides `list_agents`.
+
+### send_message
+
+Sends a message that becomes the child's next FIFO turn: a working child finishes its current turn first, so a message cannot redirect work already underway. The call returns only acceptance (the accepted message's stable `messageId`), never the child's reply — the child's transcript by its id is the source of what it did. A failure — an unauthorized or unknown child, a descriptor-less child that cannot be resumed, or rejected admission — states the message was not delivered.
+
+### interrupt_agent
+
+Stops only the target's current turn: queued messages stay parked until a later `send_message`, descendants keep running, and the child stays available for follow-ups. The call returns when the stop request is accepted, not when the target is quiet; interrupting an already-finished agent is an accepted no-op, and self, sibling, stale, and non-ancestor callers get errored results.
+
+### list_agents
+
+Lists the continuable children below the calling agent: `children` (default) shows direct children, `descendants` walks the whole tree in stable pre-order, annotating each entry with its durable direct-parent session id and depth. Status comes from the live Agent registry — `running`, `idle`, or `ready`. One-shot children are intentionally absent because they cannot accept `send_message`, and unreadable candidates appear as diagnostics.

+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains what the tools delegate to the subagent service; the observable behavior is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+Thin adapters over `ctx.subagents.followup()`, `interrupt()`, and the list projections; the tools perform no lifecycle routing. Residency, cold resume, and interrupt authorization belong to the service, and the tools pass the exact live calling agent (`exec.agent`) as the authority the service verifies against the target's recorded lineage.
+
+### Delivery and signal ownership
+
+The tool forwards its execution signal, which owns admission only until inbox acceptance. Once the child accepts a message, the accepted turn cannot be cancelled through this tool. Every message is recorded with the coordinator source `{ kind: 'coordinator', senderSessionId: parent.id }`, which the service retains but never treats as authority.
+
+### Listing projection
+
+`list_agents` derives the root id from the calling agent, reads the service catalog without a cursor, refines each candidate's status through the live Agent registry, and omits one-shot children because they cannot accept `send_message`. Diagnostics keep their positions in the descendants scope and never expose descriptor contents.

 ## Known Limitations and Deferred Work
 
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define what the control tools cannot observe or steer; they are current package constraints.
+
 - **A queued message has no independent result** — acceptance returns only its inbox `messageId`; the child's work lands in the durable child Session and is never collected through this tool. A child granted `report` may send selected content back separately, but that message is not this call's result.
 - **No steering of the current turn** — every message opens a later FIFO turn, so a message sent while the child is working runs only after its current turn finishes and cannot redirect it.
 - **Listing is a snapshot, not a delivery promise** — it may race publication, disposal, or a later message, and another process may activate a child this process reports as `ready`; cross-process accuracy requires a shared lease. `interrupt_agent` performs the authoritative live-lineage check itself, so discovery staleness cannot grant authority.
 - **No pagination or deletion** — the complete stably ordered set is returned, and persisted children remain listed for as long as their sessions remain in persistence; a service-level bound or delete operation is a later product decision.

 # @deepseek-ai/dsh-tool-subagent-control
 
 [English](README.md) | 中文
 
-可选的全局具名 `send_message`、`interrupt_agent` 与 `list_agents` 工具是 `ctx.subagents` 之上的轻量适配器。绑定提供方的 `@deepseek-ai/dsh-tool-subagent` 实例会为每种传输注册不同的委派工具；这个单独加载的包只注册一次共享控制工具，因此多个委派工具绝不会重复注册全局控制工具。根插件注册 `send_message` 与 `interrupt_agent`，且只要求 `subagents`；可单独加载的 `./list-agents` 插件注册 `list_agents`，并将 `subagents` 与 `agents` 声明为加载时依赖。其目录读取在调用时还要求会话存储与投影注册表，但不要求任何查询服务。部署可保留根插件工具并省略列表工具。是否加载这些工具不会决定委派工具是否启动可继续工作。这些工具只负责父到子的方向；单独安装的 [`@deepseek-ai/dsh-tool-subagent-report`](../tool-subagent-report/README.zh.md) 负责子到父的方向。
+## 概述
 
-本工具不执行生命周期路由：驻留与冷恢复归 subagent 服务所有。它将 `exec.agent` 作为授权投递的确切在线父级传入，并把每条消息的来源记录为 `{ kind: 'coordinator', senderSessionId: parent.id }`；服务会保留该来源，但绝不将其视为权限。每条消息都会通过 `Agent.followup()` 成为 subagent 的下一个 FIFO 轮次：如果子 agent（智能体）仍在工作，该消息会等待其当前轮次结束，因此无法重定向已经在进行的工作。本工具会转发其执行信号，该信号只在 inbox 接受之前掌管准入；一旦子 agent 接受消息，已接受的轮次便无法再通过本工具取消。本次调用不会返回子 agent 的回复；通过该 id 查看其 transcript（文本记录），才是了解它完成了哪些工作的真源。拥有 `report` 的子 agent 会自行把内容作为一条单独的父级消息发回。投递失败会变为出错的工具结果，并明确说明消息未送达。
+`dsh-tool-subagent-control` 为可继续子级添加全局控制工具：`send_message` 投递一条成为子级下一轮次的后续消息，`interrupt_agent` 停止子级当前轮次但保留其队列与后代，`list_agents`（来自可单独加载的 `list-agents` 插件）按持久化 id 与标签列出可继续子级。这些工具是全局的，因此任意数量的委派工具都不会产生重复。这些工具只覆盖父到子方向；子到父方向属于独立安装的 `dsh-tool-subagent-report`。是否加载这些工具不会决定委派工具是否启动可继续工作。
 
-`interrupt_agent(agent_id)` 将 `exec.agent` 作为 `ctx.subagents.interrupt()` 的确切在线 ancestor 授权传入：目标可以是直接 child 或更深的后代，由服务——而不是本工具——依据目标 Activation 记录的 lineage 校验调用方。只有目标的当前轮次会停止（`keepInbox`）：已排队的消息保持暂停直到之后的 `send_message`，已发布的后代继续运行，child 也仍可接受后续消息。调用在停止请求被接受后立即返回，不等待目标完全停稳；目标不存在或已结算是被接受的 no-op，而 self、sibling、陈旧与非 ancestor 调用方会成为出错结果。
+## 目录
 
-`list_agents` 接受一个可选的 `scope` 参数，会从调用它的 agent 推导根 id，并且不使用 cursor，将服务目录投影为可继续 child。默认的 `children` scope 读取 `ctx.subagents.listChildren()`；`descendants` 读取 `ctx.subagents.listDescendants()`，其单份语料的遍历会穿过普通会话与一次性 child，并按稳定 pre-order 以 `parent=<id> depth=<n>` 渲染保留下来的条目。`parent` 注释是持久化直接 parent 会话 id，可能指向输出中省略的普通会话。对于调用本工具的 agent，只有 depth-1 child 条目可作为 `send_message` 候选；更深的 child 条目只能作为 `interrupt_agent` 候选。状态来自在线 Agent 注册表：`running`（driver 活跃）、`idle`（驻留但处于轮次之间，可能在等待它启动的 agent）或 `ready`（仅存于存储，表示可恢复而非终态）。服务结果还包含由会话支撑的一次性 subagent，以供 UI 等消费方使用；但这些条目无法接受 `send_message`，因此会从这个模型工具中排除。diagnostic 仍然可见，并在 descendants scope 中带有位置。持久化身份和模式来自每个子 agent 的描述符，消息送达时的鉴权和 Activation 所有权检查仍归服务负责。

+## 使用本包
+
+在模型需要对可继续子级发消息、中断或列出的任何组合中挂载本包。根插件只需要 subagent 服务；列表工具是独立插件，部署方可以省略。
+
+### 最小配置
+
+先加载 subagent 服务、一个后端、委派工具与本包。加上独立的列表插件即可公开全部三个工具：
+
+```yaml
+- name: '@deepseek-ai/dsh-subagent'
+- name: '@deepseek-ai/dsh-subagent-spawn-in-process'
+- name: '@deepseek-ai/dsh-tool-subagent'
+  config:

+    backgroundMode: continuable
+- name: '@deepseek-ai/dsh-tool-subagent-control'
+- name: '@deepseek-ai/dsh-tool-subagent-control/list-agents'
+```
+
+本包不接收任何配置：根插件提供 `send_message` 与 `interrupt_agent`，列表插件提供 `list_agents`。
+
+### send_message
+
+发送一条消息，使之成为子级的下一 FIFO 轮次：正在工作的子级会先完成其当前轮次，因此消息无法重定向已经进行的工作。调用只返回接受结果（被接受消息的稳定 `messageId`），绝不返回子级的回复——通过其 id 查看子级 transcript（文本记录）才是它完成了哪些工作的真源。失败——未授权或未知子级、缺少描述符而无法恢复的子级，或准入被拒——会明确说明消息未送达。
+
+### interrupt_agent
+
+只停止目标当前轮次：已排队消息保持暂停直到之后的 `send_message`，后代继续运行，子级仍可接受后续消息。调用在停止请求被接受后立即返回，不等待目标完全停稳；中断已结束的 agent 是被接受的 no-op，而 self、sibling、陈旧与非 ancestor 调用方会收到出错结果。
+
+### list_agents
+
+列出调用 agent 下方的可继续子级：`children`（默认）只显示直接子级，`descendants` 按稳定 pre-order 遍历整棵树，并为每个条目标注其持久化直接父级会话 id 与深度。状态来自在线 Agent 注册表——`running`、`idle` 或 `ready`。一次性子级因无法接受 `send_message` 而被有意排除，无法读取的候选项以 diagnostic 呈现。

+
+### 投递与信号所有权
+
+工具转发其执行信号，该信号只在 inbox 接受之前掌管准入。子级一旦接受消息，已接受的轮次便无法再通过本工具取消。每条消息都记录协调者来源 `{ kind: 'coordinator', senderSessionId: parent.id }`；服务会保留该来源，但绝不将其视为权限。
+
+### 列表投影
+
+`list_agents` 从调用 agent 推导根 id，不使用 cursor 读取服务目录，通过在线 Agent 注册表细化每个候选的状态，并省略无法接受 `send_message` 的一次性子级。diagnostic 在 descendants scope 中保留其位置，且绝不暴露描述符内容。

 # @deepseek-ai/dsh-tool-subagent-report
 
 English | [中文](README.zh.md)
 
-The optional child-scoped `report` tool is a thin adapter over `ctx.subagents.reportFrom()`. It gives every continuable in-process child a return channel to the Agent that started it, and installs the prompt section that instructs the child to use it. The package registers a continuable-child setup contribution instead of a global tool, so the tool and its guidance exist only inside those children. Roots, one-shot subagents, remote subagent providers, sibling scopes, and agentless tool execution never present or execute it. Installing this package grants only that child-scoped capability; the parent-to-child direction remains the independent [`@deepseek-ai/dsh-tool-subagent-control`](../tool-subagent-control/README.md), and continuable mode depends on neither package.
+## Summary
 
-The child-scoped `tool:report` prompt section instructs the child to call `report` once before finishing, with a self-contained answer, and earlier whenever a partial finding changes what the parent should do next. The instruction is guidance, not enforcement: the mechanism still accepts zero or many calls in one turn, and no runtime path rejects a child that never reports. A successful call neither concludes the turn, settles the Activation, nor prevents later parent follow-ups, and finishing a turn never reports automatically. The tool accepts no recipient: `exec.agent` is the sender's exact live Agent and the authority credential, and the service derives the sole recipient from that child's durable `parentSession`. Success returns the stable `MessageId` of the parent-accepted message, not a read receipt, an inbox-occurrence id, a parent-log acknowledgement, a turn-completion receipt, or a persistence flush. A parent absent from the registry fails the call with `direct parent is not live; report was not delivered` — registry presence governs parent resolution, and a registered parent already in host-owned disposal still accepts while its log admits appends. The service performs no injection, parent cold resume, or offline mailbox write; the durable child transcript remains the recovery source, and a failed tool call does not prove non-delivery (a later `tools/post-execute` veto can fail a call whose report was already accepted).
+`dsh-tool-subagent-report` gives every continuable in-process child a return channel to the agent that started it: it installs a child-scoped `report` tool plus the prompt guidance that tells the child to use it. The tool and its guidance exist only inside those children — roots, one-shot subagents, remote providers, and sibling scopes never see them. Accepted reports reach the parent as ordinary parent messages, framed as `Background subagent <child-id> reported:`. Continuable mode depends on neither this package nor the control package; this one owns only the child-to-parent direction.
 
-`reportDelivery` selects parent scheduling for every accepted report. `next-step` (the default) uses `parent.steer()`: a running parent receives the report at its nearest safe step boundary, while an idle parent starts a turn. Reports accepted in sequence share the next-step FIFO, including the later manager-authored settlement notice, so the parent cannot observe settlement before an earlier report; reports waiting together enter one claimed batch. `quiet` uses `parent.inject()`, adding the same next-step context without waking a parked parent. This is deployment scheduling policy, so the model-facing schema cannot select or override it per call.
+## Table of Contents
 
-Scope-local registration deliberately survives the child's global `toolFilter`, so a delegation allow-list cannot remove the only return channel. A deployment that requires a child with no return channel omits this package.

+## Use this package
+
+Mount this package in a composition with continuable in-process children whose findings the parent should see before they finish. The tool and its guidance appear automatically inside each continuable child; no per-child configuration is needed.
+
+### Minimal configuration
+
+Load the subagent service, a backend, the delegation tool in `continuable` mode, and this package:
+
+```yaml
+- name: '@deepseek-ai/dsh-subagent'
+- name: '@deepseek-ai/dsh-subagent-spawn-in-process'
+- name: '@deepseek-ai/dsh-tool-subagent'
+  config:
+    provider: spawn
+    backgroundMode: continuable
+- name: '@deepseek-ai/dsh-tool-subagent-report'
+```
+
+| Field | Default | Meaning |
+|---|---|---|
+| `reportDelivery` | `next-step` | Parent scheduling for accepted reports: `next-step` wakes the parent at its nearest step boundary; `quiet` adds the same context without waking it |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-tool-subagent-report) is the exhaustive source for every accepted field and its JSDoc.
+
+### What the child gets
+
+Each continuable child gets a `report` tool whose only parameter is `output` — a self-contained answer for the parent — and a prompt section telling it to call `report` once before finishing, and earlier whenever a partial finding changes what the parent should do next. The instruction is guidance, not enforcement: a child may call zero or many times in one turn, and finishing a turn never reports automatically. A successful call neither ends the turn nor settles the child's Activation.
+
+### What the parent sees
+
+An accepted report becomes one user-role parent message framed as `Background subagent <child-id> reported:` followed by the child's exact output, with a durable source naming the child. `next-step` delivery wakes an idle parent or joins a running parent's nearest step boundary; `quiet` delivery adds the same context without waking the parent. The tool takes no recipient: the service derives the sole recipient from the child's durable `parentSession`.
+
+### Scope and direction
+
+The report tool deliberately survives the child's global `toolFilter`: a delegation allow-list cannot remove the only return channel. A deployment that requires a child with no return channel omits this package. The parent-to-child direction remains the independently installed control package, and continuable mode depends on neither package.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the tool is installed and scheduled; the observable behavior is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The package registers a continuable-child setup contribution rather than a global tool, so the tool and its guidance are installed inside each child's unpublished scope and vanish with it. The same registrations are ordinary child-scoped contributions, so an expert `system-prompt/assemble` listener could replace them and would then own preserving the reporting protocol for that child.
+
+### Delivery scheduling
+
+`next-step` uses `parent.steer()`: a running parent receives the report at its nearest safe step boundary, an idle parent starts a turn, and reports accepted in sequence share the next-step FIFO. `quiet` uses `parent.inject()`, adding the same next-step context without waking a parked parent. Both are deployment policy: the model-facing schema cannot select or override delivery per call.
+
+### Exported contribution
+
+`installReportTool(childCtx, ctx, delivery)` installs the tool and guidance into a minted child scope and returns one disposer revoking both. The generated tool catalog uses this path because the global registry cannot expose a scope-local schema; production composition still enters through `apply()`.

 ## Known Limitations and Deferred Work
 
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define what an accepted report does and does not guarantee; they are current package constraints.
+
 - **A parent whose host-owned disposal already started can still accept** — `AgentHandle.dispose()` cancels, awaits quiescence, and only then unwinds the scope and leaves the registry; it exposes no signal for "disposal started." A report accepted in that window is appended to the parent's transcript, but that parent will not act on it in this process. A continuation-manager-owned parent rejects forest teardown through the manager's admission boundary.
 - **Acceptance is weaker than durable delivery** — there is no durable mailbox, idempotency key, delivery receipt, retry protocol, or exactly-once claim. A process failure after one side recorded acceptance leaves the outcome ambiguous, and an external retry may duplicate the report.
 - **A staged quiet report is not immediately reconstructable** — acceptance returns its stable `MessageId`, but the parent Session reconstructs the framed content only after pending context reaches its ordinary log boundary.
 - **Granting waits for the next Activation; revocation is immediate** — installing this package after a child becomes resident grants `report` and its guidance only on that child's next Activation, while removing the package revokes both from resident children immediately.
 - **Nested reporting reaches exactly one edge upward** — a grandchild reports to its direct child parent, never to the top-level coordinator, which must explicitly report a derived update later.
 - **No rate limiting** — the default `next-step` mode can amplify model work when nested children report frequently, although reports waiting together share one step; a deployment that accepts unread reports over that amplification selects `quiet`.

 # @deepseek-ai/dsh-tool-subagent-report
 
 [English](README.md) | 中文
 
-可选的子级作用域 `report` 工具是 `ctx.subagents.reportFrom()` 之上的轻量适配器。它为每个可继续的进程内子级提供一条返回通道，指向启动该子级的 Agent（智能体），并安装指示子级使用该通道的提示词 section。本包注册的是可继续子级设置贡献，而不是全局工具，因此该工具及其指引只存在于这些子级内部。根 Agent、一次性 subagent、远程 subagent 提供方、同级作用域以及不关联 Agent 的工具执行都不会提供或执行它。安装本包只授予这项子级作用域能力；父到子方向仍由独立的 [`@deepseek-ai/dsh-tool-subagent-control`](../tool-subagent-control/README.zh.md) 负责，可继续模式不依赖这两个包中的任一个。
+## 概述
 
-子级作用域的 `tool:report` 提示词 section 要求子级在结束前调用一次 `report` 并给出自足的答案，并在部分发现会改变父级下一步动作时提前上报。该指令是引导而非强制：机制本身仍接受一个轮次中调用零次或多次，也没有任何运行时路径会拒绝从不上报的子级。调用成功既不会结束轮次或结算 Activation，也不会阻止父级后续消息；轮次结束也绝不会自动上报。该工具不接受接收方参数：`exec.agent` 是发送方确切在线的 Agent，也是权限凭据；服务根据该子级持久化的 `parentSession` 推导唯一接收方。成功时返回父级已接受消息的稳定 `MessageId`，不表示已读回执、inbox 中该次出现的 id、父级日志确认、轮次完成回执或持久化刷盘。父级解析由注册表中的存在性决定：父级不在注册表时，调用失败并返回 `direct parent is not live; report was not delivered`；已开始由宿主管理的 dispose（资源释放）但仍在注册表中的父级在其日志仍接受追加时仍会接受。服务不会执行注入、父级冷恢复或离线 mailbox 写入；持久化子级 transcript（文本记录）仍是恢复依据，且工具调用失败不能证明未送达（后续 `tools/post-execute` 否决可能让报告已被接受的调用以失败结束）。
+`dsh-tool-subagent-report` 为每个可继续的进程内子级提供一条返回通道，指向启动它的 agent（智能体）：它安装子级作用域的 `report` 工具，以及指示子级使用该工具的提示词指导。工具及其指导只存在于这些子级内部——根 agent、一次性 subagent、远程提供方与同级作用域永远看不到它们。被接受的报告会以普通父级消息到达父级，前缀为 `Background subagent <child-id> reported:`。可继续模式不依赖本包，也不依赖控制包；本包只负责子到父方向。
 
-`reportDelivery` 为每条已接受的报告选择父级调度方式。`next-step`（默认值）使用 `parent.steer()`：运行中的父级会在最近的安全 step 边界收到报告，空闲父级则会启动一个轮次。按顺序接受的报告会共享 next-step FIFO，稍后由管理器撰写的结算通知也进入该队列，因此父级不会在更早的报告之前看到结算；一起等待的报告会进入同一个领取批次。`quiet` 使用 `parent.inject()`，添加相同的 next-step 上下文，但不会唤醒停驻的父级。这是部署调度策略，因此面向模型的 schema 不能在单次调用中选择或覆盖该策略。
+## 目录
 
-作用域局部注册有意不受子级全局 `toolFilter` 影响，因此委派允许列表无法移除唯一的返回通道。需要子级不具备返回通道的部署应省略本包。

+## 使用本包
+
+在包含可继续进程内子级、且父级应在子级结束前看到其发现的组合中挂载本包。工具及其指导会自动出现在每个可继续子级内部；无需任何按子级的配置。
+
+### 最小配置
+
+先加载 subagent 服务、一个后端、处于 `continuable` 模式的委派工具与本包：
+
+```yaml
+- name: '@deepseek-ai/dsh-subagent'
+- name: '@deepseek-ai/dsh-subagent-spawn-in-process'
+- name: '@deepseek-ai/dsh-tool-subagent'
+  config:
+    provider: spawn
+    backgroundMode: continuable
+- name: '@deepseek-ai/dsh-tool-subagent-report'
+```
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `reportDelivery` | `next-step` | 已接受报告的父级调度：`next-step` 在最近 step 边界唤醒父级；`quiet` 添加相同上下文但不唤醒 |
+
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-tool-subagent-report)是每个受支持字段及其 JSDoc 的穷尽式真源。
+
+### 子级获得什么
+
+每个可继续子级都会获得一个 `report` 工具，其唯一参数是 `output`——给父级的自足答案——以及一段提示词 section，指示子级在结束前调用一次 `report`，并在部分发现会改变父级下一步动作时提前调用。该指令是引导而非强制：一个轮次内子级可以调用零次或多次，结束轮次也绝不会自动上报。调用成功既不会结束轮次，也不会结算子级的 Activation。
+
+### 父级看到什么
+
+被接受的报告会成为一条用户角色的父级消息，以 `Background subagent <child-id> reported:` 开头，后接子级未经改动的输出，并带有指明子级的持久化来源。`next-step` 投递会唤醒空闲父级，或加入运行中父级最近的 step 边界；`quiet` 投递添加相同上下文但不唤醒父级。工具不接受接收方参数：服务根据子级持久化的 `parentSession` 推导唯一接收方。
+
+### 作用域与方向
+
+`report` 工具有意不受子级全局 `toolFilter` 影响：委派允许列表无法移除唯一的返回通道。要求子级不具备返回通道的部署应省略本包。父到子方向仍由独立安装的控制包负责，可继续模式不依赖这两个包中的任一个。

+
+本节解释工具的安装与调度方式；可观察行为已在[使用本包](#use-this-package)中说明。
+
+### 设计理念
+
+本包注册的是可继续子级设置贡献，而非全局工具，因此工具及其指导安装于每个子级未发布的作用域内部，并随其一同消失。这些注册都是普通的子级作用域贡献，因此专家级 `system-prompt/assemble` 监听器可以替换它们，替换后则由其负责为该子级保留上报协议。
+
+### 投递调度
+
+`next-step` 使用 `parent.steer()`：运行中的父级在最近的安全 step 边界接收报告，空闲父级启动一个轮次，按顺序接受的报告共享 next-step FIFO。`quiet` 使用 `parent.inject()`，添加相同的 next-step 上下文但不唤醒停驻的父级。两者都是部署策略：面向模型的 schema 不能在单次调用中选择或覆盖投递方式。
+
+### 导出的贡献
+
+`installReportTool(childCtx, ctx, delivery)` 把工具及其指导安装到新创建的子级作用域中，并返回同时撤销两者的唯一 disposer。生成工具目录使用这条路径，因为全局注册表无法公开作用域局部 schema；生产组合仍通过 `apply()` 进入。

-The model-facing delegation tool over one configured `ctx.subagents` provider. Changing the provider changes transport without changing the execution contract.
+## Summary
 
-## Provider selection and lifecycle
+`dsh-tool-subagent` is the model-facing delegation tool: it turns one configured `ctx.subagents` provider into a tool the agent can call to start a child agent. Changing the provider changes the transport without changing the execution contract, so one composition can expose several delegation tools, each bound to a different backend. Calls wait for the child by default under `one-shot` policy, or start work in the background by default under `continuable` policy, which returns a durable child id the model can message later. An eligible instance can also let the model discover and select the child's LLM provider, model, and reasoning effort. The tool's descriptions adapt to whether the child inherits the parent's completed turns, and failed runs surface as errored tool results rather than partial success.
 
-Each plugin instance binds one subagent transport `provider` to one `toolName`; the model cannot change that transport. Load another distinctly named instance to expose another transport. `enableModelSelection: true`, or an enabled Host preference when `modelSelectionSettings: true`, requires that provider's child `agentOptions` capability and exposes optional child LLM `provider`, `model`, and `reasoning_effort` fields without additional route configuration. A call may supply a complete provider/model pair, or only an effort when configured, parent, or provider-owned route defaults supply the effective route. Static `provider.agentRouteDefaults`, when present, form the provider/model baseline; tool config and model fields overlay it before route-aware effort merging and exact-route preflight. Providers without those defaults retain compatible missing values from the parent's latest logged request selection, falling back to its creation options before the first request and retaining its configured `maxTokens`. Changing provider or model without naming an effort clears the lower layer's route-owned effort so the selected model resolves its default.
+## Table of Contents
 
-The delegation tool registers only while its subagent provider exists, avoiding sibling load-order and provider-reload dependencies. When model selection is enabled, its optional fields remain visible without `ctx.llm`; a call that selects a route rejects if the service is unavailable. When disabled, the schema omits those fields and execution rejects a forced selection. Configured `agentOptions` remain deployment-owned child defaults independently of this model-facing switch. Adapter catalog and topology changes do not rewrite or re-register the tool. Its description follows `provider.inheritsParentContext`: fresh children require standalone prompts, while forked children already see completed parent turns.

-An enabled definition registers `list_subagent_models`, which lists registered providers, one provider's advertised models, or one exact model's reasoning efforts at call time. At most one instance in a tool scope may enable selection because this discovery tool has a global name; duplicate owners fail registration. Shipped product compositions default the primary `subagent` (`spawn`) instance off and sample the Host `subagent-model-selection.enabled` preference when each new top-level session is composed. The enabled decision is logged as `subagent/model-selection-enabled`, inherited by child sessions, and retained on resume; later settings edits do not change a running session. Shipped compositions deliberately keep `subagent_fork` disabled so the fork inherits the parent's provider and model: changing that route would forfeit provider-side KV Cache reuse of the inherited conversation prefix and can make prefix recomputation dominate the delegated task's cost. This restriction remains even if discovery ownership is separated. Catalog membership remains advisory: an enabled delegation tool accepts an unlisted model id when its adapter does. The [model-selected route Agent Note](../../../.agents/notes/implemented/feature/2026-08-18-model-selected-subagent-routes.md) owns the rationale and reintroduction condition.
+-----
 
-A foreground call passes the execution signal through startup and execution, awaits `run.result`, and always awaits `run.dispose()` before returning. Only `completed` returns the canonical `{ kind: 'foreground', runId, output: JsonValue[] }`, rendered as the same final text. Abort, refusal, token limit, and other failures become errored tool results whose message contains the stop-reason headline, an optional provider-authored `SubagentResult.diagnostic`, and then any preserved partial assistant text. The diagnostic remains separate from `SubagentResult.output`, so a truncated answer is never reported as success or confused with infrastructure detail. If result collection and disposal both reject, the errored result preserves both failures.
+<a id="use-this-package"></a>
+## Use this package
 
-`backgroundMode` selects both the background route and the omitted `run_in_background` default. `one-shot` waits in the foreground by default; an explicit `true` registers a plain parent-owned Task and returns canonical `{ kind: 'background', jobId }`, rendered as `started background subagent job <id>`, even when the provider supports continuable children. Generic task tools own its later status, collection, cancellation, and notices; a failed Task keeps the stop reason and the same optional provider diagnostic in its detail. `continuable` runs in the background when the argument is omitted or `true`; an explicit `false` waits for the result in the foreground. Its background route requires a provider with the `prepareContinuable` capability, calls `ctx.subagents.startContinuable()`, and returns `{ kind: 'continuable', subagentId }`, rendered as `started subagent <childId>`. The route resolves at inbox acceptance: the child owns its own turns from there, so this call neither waits for nor collects a result. The child's transcript by that id remains the source of its detailed output, and the optional global `send_message` tool sends it more work. The continuation service delivers one settlement notice whenever the child's Activation ends, containing its outcome and any final assistant message independently of `report`. Starting continuable work does not require `send_message` to be loaded. See the [background subagent Agent Note](../../../.agents/notes/implemented/feature/2026-07-08-background-subagent-tasks.md), the [continuable subagents Agent Note](../../../.agents/notes/implemented/feature/2026-07-28-continuable-subagent-conversations.md), and the [background-first delegation Agent Note](../../../.agents/notes/implemented/feature/2026-08-11-background-first-continuable-delegation.md).
+Mount one instance per delegation target, each with a distinct `toolName`. The tool exists exactly while its provider does, so sibling load order and provider reloads never strand it.
 
-`toolFilter` changes the child's global tool layer but is not a parent-derived authority ceiling. See the [agent-scope security non-goal](../../../.agents/notes/implemented/architecture/2026-07-08-agent-scope-contexts.md#security-and-authority-are-non-goals).
+### Minimal configuration
 
-## Config
+Load the subagent service, an in-process or remote backend, and this tool; then name the provider. This composition exposes a `subagent` tool that delegates to the `spawn` backend:
 
-| Key | Meaning |
+```yaml
+- name: '@deepseek-ai/dsh-subagent'
+- name: '@deepseek-ai/dsh-subagent-spawn-in-process'
+- name: '@deepseek-ai/dsh-tool-subagent'
+  config:
+    provider: spawn
+    toolName: subagent
+```
+
+| Field | Default | Meaning |
+|---|---|---|
+| `provider` | required | Provider name on `ctx.subagents` (e.g. `spawn`, `fork`, `acp`) |
+| `toolName` | `subagent` | Model-facing tool name; distinct for every loaded instance |
+| `enableModelSelection` | `false` | Statically expose child LLM selection fields and register `list_subagent_models`; requires provider `agentOptions` support |
+| `modelSelectionSettings` | `false` | Sample the Host preference for each new top-level Session; mutually exclusive with `enableModelSelection` and valid only in Agent scope |
+| `enableRunInBackground` | `true` | Expose `run_in_background`; disabling also rejects forced background calls |
+| `backgroundMode` | `one-shot` | Background policy: `one-shot` defaults calls to foreground; `continuable` defaults them to background and requires the provider's `prepareContinuable` capability |
+| `agentOptions` | — | Configured child `provider`, `model`, adapter-owned `reasoningEffort`, and positive `maxTokens` defaults; requires provider `agentOptions` support and overlays any provider-owned route defaults |
+| `persona` | — | Per-child persona; requires the provider's `persona` capability |
+| `toolFilter` | — | Per-child global-tool restriction; requires the `toolFilter` capability |
+| `maxDepth` | `3` | Absolute delegation-depth cap (`0` forbids delegation); `'provider-managed'` sends no cap to an out-of-process provider |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-tool-subagent) is the exhaustive source for every accepted field and its JSDoc.
+
+### Foreground and background modes
+
+Under `one-shot` policy, an omitted `run_in_background` waits in the foreground and returns the child's final text; `run_in_background: true` starts a plain parent-owned background job and returns `started background subagent job <id>`, collected with `job_output` and stopped with `job_kill`.
+
+Under `continuable` policy, an omitted or `true` `run_in_background` starts a durable child and returns `started subagent <childId>` without waiting for a result; the runtime delivers one settlement notice when the child's Activation ends, and the optional `send_message` tool sends it more work. Set `run_in_background: false` to wait for the result in the foreground.
+
+`maxDepth` caps recursion (default `3`; `0` forbids delegation) and requires a provider with the `depthLimit` capability; `'provider-managed'` leaves the budget to an out-of-process provider. `persona` and `toolFilter` configure every child when the provider supports them, and the tool stays visible at the cap — each attempted start checks the calling agent's current depth and rejects with an errored result.
+
+### Selecting a child LLM
+
+Set `enableModelSelection: true` to expose optional `provider`, `model`, and `reasoning_effort` fields and register the shared `list_subagent_models` tool. Alternatively, set `modelSelectionSettings: true` to sample the Host's `subagent-model-selection.enabled` preference when each top-level Session is composed. That decision is recorded in the Session, inherited by child Sessions, and unchanged by later settings edits. These modes are mutually exclusive and require a backend that advertises `agentOptions`; ACP, Codex, and Claude Code reject them, while DSH SDK supports route selection.
+
+A call supplies `provider` and `model` together, or supplies only an effort when configured, parent, or provider-owned defaults provide the route. Static `provider.agentRouteDefaults`, when present, form the provider/model baseline; tool configuration and model fields overlay it before route-aware effort merging and exact-route preflight. Providers without these defaults use compatible values from the parent's latest logged request, then the parent's creation options before its first request, while retaining the configured `maxTokens`. Changing the route without an explicit effort clears the inherited route-owned effort, so the selected model resolves its default. The live LLM adapter validates the effective route before child creation. Catalog membership remains advisory, so a model can use an unlisted id when its adapter accepts it.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the tool mirrors provider lifecycle and settles runs; the observable behavior is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+One instance is one provider plus one tool name. The plugin mirrors provider lifecycle: it registers the tool when the named provider appears and disposes it when the provider leaves, so sibling load order and HMR replacement cannot strand a dangling tool. A numeric `maxDepth` or configured LLM selection the provider cannot enforce fails the mount instead of the first delegation. At most one instance in a tool scope may own model selection because `list_subagent_models` has a global name.
+
+### Foreground settlement
+
+A foreground call awaits `run.result`, maps every non-completed stop reason to an error headline, appends the provider diagnostic and any preserved partial assistant text, and always awaits `run.dispose()` before returning; when result collection and disposal both reject, the errored result preserves both failures.
+
+### Background routes
+
+One-shot background registers a plain parent-owned Task whose done channel settles the start and keeps the stop reason and optional provider diagnostic in its detail. Continuable background calls `ctx.subagents.startContinuable()`, which resolves at inbox acceptance: the child owns its own turns from there, so the call neither waits for nor collects a result.
+
+### Context-sensitive wording
+
+The tool's description derives from `provider.inheritsParentContext`: a fresh child gets "it does not see this conversation" wording, a forked child gets "it does not see the current in-flight turn" wording, so the model never restates or omits context that does not exist.
+
+### Source map
+
+| File | Role |
 |---|---|
-| `provider` (required) | Provider name (`spawn`, `fork`, `acp`, ...). |
-| `toolName` | Model-facing name, default `subagent`; distinct for every loaded instance. |
-| `enableModelSelection` | Exposes and accepts model-facing child LLM selection fields and registers the shared `list_subagent_models` tool, default `false`. It requires the subagent provider's `agentOptions` capability. At most one instance in a tool scope may enable it; the discovery schema remains registered without `ctx.llm`, while discovery and selected-route calls reject until that optional service is available. Configured `agentOptions` remain available when this switch is disabled. |
-| `modelSelectionSettings` | Samples the Host `subagent-model-selection` preference while composing an Agent, records an enabled decision in its Session, and inherits that decision in child Sessions. Default `false`; mutually exclusive with `enableModelSelection` and valid only in an Agent-scoped composition. The preference defaults off and changes only subsequently composed top-level Sessions. |
-| `enableRunInBackground` | Exposes background mode, default `true`; disabling also rejects forced background calls. |
-| `backgroundMode` | Background lifecycle policy, default `one-shot`. `one-shot` defaults calls to foreground; `continuable` defaults them to background, requires the provider's `prepareContinuable` capability, and returns a durable child id without requiring the follow-up tool. |
-| `agentOptions` | Configured child LLM `provider`, `model`, adapter-owned `reasoningEffort`, and positive `maxTokens`; requires the subagent provider's `agentOptions` capability. Static provider route defaults, when present, are merged before tool config and model overrides; otherwise in-process providers merge explicit values over the parent's latest logged request selection, or its creation options before the first request. An inherited effort survives only while the effective provider/model route is unchanged; changing the route without an explicit effort lets the selected model supply its default. A configured provider, model, or effort is checked through the optional `ctx.llm` service before child creation even when the call omits model-selection fields; a missing service or invalid value rejects the call. |
-| `persona` | Per-child persona; requires provider `persona` capability. |
-| `toolFilter` | Per-child global-tool restriction; requires `toolFilter` capability. |
-| `maxDepth` | Absolute delegation-depth cap, default `3` (`0` forbids delegation); a numeric cap requires the `depthLimit` capability and fails the mount without it. `'provider-managed'` sends no cap for an out-of-process provider whose budget belongs to the child harness. The tool stays visible at the cap; each attempted start checks the calling agent's current depth and returns an errored tool result when rejected. |

-## Concurrency
+</details>
 
-Foreground and background calls are concurrency-safe: sibling delegations in one assistant message overlap under the loop's rolling pool (`maxParallelToolCalls`), and results still commit in model order. Children work in their own sessions and a run never mutates the parent session; the one-shot background form's one parent-owned write — registering a Task — is a synchronous, commutative insertion that tolerates concurrent dispatch, so overlapping background calls acquire their job ids in dispatch-race order. Coordinating sibling workspace effects belongs to the model, exactly as it already does for background and continuable children. See the [parallel subagent Agent Note](../../../.agents/notes/implemented/feature/2026-08-09-parallel-subagent-delegations.md) and the [parallel tool-call Agent Note](../../../.agents/notes/implemented/feature/2026-07-10-parallel-tool-call-execution.md).

 ### Tool schema
 
 #### What the model sees
 
-The generated default [`subagent` schema](../../../docs/tool-catalog.md#deepseek-aidsh-tool-subagent) under this instance's configured name while its provider exists. `enableModelSelection` adds `provider`, `model`, and `reasoning_effort` plus inheritance and selection guidance; the provider must support `agentOptions`. Provider context inheritance changes the tool and prompt descriptions. Enabled background mode adds `run_in_background`: continuable mode documents its `true` default, runtime settlement notice, and explicit foreground override, while one-shot mode documents its `false` default and the job id collected with `job_output` or stopped with `job_kill`. While the tool is visible in an assembly's scope, a `tool:<toolName>` system-prompt section tells the model to start independent continuable delegations together, keep working while they run, and choose foreground only when its next action depends on the result; a tool restriction removes both its schema and this guidance.

-An instance with static `enableModelSelection: true`, or a settings-controlled instance whose Session decision is enabled, exposes the child LLM selection fields and `list_subagent_models`. Calls reject while the optional `ctx.llm` service is unavailable. With no arguments the discovery tool returns registered provider ids and names; with `provider` it returns that adapter's advertised models; with `provider` and `model` it resolves the exact model and returns its advertised reasoning efforts and default. The result is read-only runtime metadata, not an authorization list.

 ## Known Limitations and Deferred Work
 
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define what this tool does not return or enforce; they are current package constraints.
+
 - **Background runs expose no result through this tool** — a one-shot task's final output is collected through the generic task surface, and a continuable child's output stays in its own session, read by its subagent id. The settlement notice states how that child ended and carries any final assistant message, but it is not this call's return value and cannot be awaited here.
 - **Duplicate names across waiting one-shot instances are detected late** (`TODO(subagent-dup-toolname)`) — continuable instances reserve their prompt-section name during plugin application, but preventing provider-registration rollback for waiting one-shot instances requires a registry of intended names.
-- **Shipped fork tools cannot select a child LLM route** — they inherit the parent's provider and model to keep the copied conversation prefix eligible for KV Cache reuse. Re-enable the fields only when route changes preserve reuse or expose a bounded recomputation cost.
-- **Non-routing child policy is fixed per instance** — another persona, tool filter, or depth cap requires another distinctly named tool. LLM provider/model/reasoning-effort selection requires static enablement or an enabled per-Session preference and a subagent provider that advertises `agentOptions`; ACP, Codex, and Claude Code reject it rather than ignore it.

+`dsh-tool-subagent` 是面向模型的委派工具：它把一个已配置的 `ctx.subagents` 提供方变成 agent 可以调用来启动子 agent（智能体）的工具。更换提供方只会改变传输，不会改变执行约定，因此一个组合可以暴露多个委派工具，各自绑定不同的后端。`one-shot` 策略下，调用默认在前台等待子 agent；`continuable` 策略下，调用默认在后台启动工作，并返回模型之后可以发消息的持久化子 agent id。合适的实例还可让模型发现并选择子 agent 的 LLM 提供方、模型与推理等级。工具的描述会随子 agent 是否继承父级已完成轮次而调整，失败的运行以出错的工具结果呈现，而非部分成功。
 
-每个插件实例把一个 subagent 传输 `provider` 绑定到一个 `toolName`；模型不能改变该传输。如需公开另一种传输，请加载另一个名称不同的实例。`enableModelSelection: true`，或 `modelSelectionSettings: true` 时已启用的 Host 偏好，都要求该提供方具备子级 `agentOptions` 能力，并且无需额外路由配置即可公开可选的子 agent LLM `provider`、`model` 与 `reasoning_effort` 字段。调用可以提供完整的提供方／模型对；当配置值、父 Agent 值或提供方持有的路由默认值能够提供生效路由时，也可以只提供推理强度。静态的 `provider.agentRouteDefaults` 在存在时构成 provider／model 基线；工具配置与模型字段会在路由相关强度合并和确切路由预检前覆盖它。没有这些默认值的提供方会从父 Agent 最新记录的请求选择中保留兼容的缺失值；首个请求之前回退到其创建选项，并保留其中配置的 `maxTokens`。如果更换提供方或模型但没有指定强度，则清除下层路由所属的强度，使所选模型解析自己的默认值。
+## 目录
 
-委派工具只在其 subagent 提供方存在时注册，从而避免对同级加载顺序和提供方重新加载的依赖。启用模型选择时，即使没有 `ctx.llm`，可选字段仍然可见；选择路由的调用会在该服务缺失时失败。禁用时，schema 会省略这些字段，执行阶段也会拒绝强制传入的选择。配置的 `agentOptions` 仍是部署方所有的子级默认值，不受这个面向模型的开关影响。adapter 目录和拓扑变化不会改写或重新注册工具。工具描述遵循 `provider.inheritsParentContext`：新建子 agent（智能体）需要独立提示词，而 fork 子 agent 已能看到父级已完成轮次。

-启用的定义会注册 `list_subagent_models`，它会在调用时列出已注册提供方、某个提供方公布的模型，或某个精确模型的推理强度。因为发现工具使用全局名称，一个工具作用域最多只能由一个实例启用选择；多个持有方会使注册失败。随附产品组合默认关闭主 `subagent`（`spawn`）实例，并在每个新的顶层会话完成组合时读取 Host 的 `subagent-model-selection.enabled` 偏好。启用决定记录为 `subagent/model-selection-enabled`，由子会话继承并在恢复时保留；之后修改设置不会改变运行中的会话。组合会刻意在 `subagent_fork` 上保持禁用，使 fork 继承父级的提供方与模型：更改该路由会失去继承对话前缀的提供方侧 KV Cache 复用，重新计算前缀的成本可能超过委派任务本身。即使分离发现工具的持有权，该限制也仍然成立。目录条目仍只提供建议：如果适配器接受未列出的模型 ID，启用选择的委派工具也会接受。理由与重新开放条件由[模型选择路由 Agent Note](../../../.agents/notes/implemented/feature/2026-08-18-model-selected-subagent-routes.zh.md)负责。
+-----
 
-前台调用会让执行信号贯穿启动和执行，等待 `run.result`，并且在返回前总会等待 `run.dispose()`。只有 `completed` 会返回规范值 `{ kind: 'foreground', runId, output: JsonValue[] }`，并渲染为相同的最终文本。中止、拒绝、token 上限和其他失败都会变成出错的工具结果，其消息依次包含终止原因标题、可选的提供方 `SubagentResult.diagnostic`，以及子 agent 保留下来的部分 assistant 文本。诊断与 `SubagentResult.output` 保持分离，因此被截断的回答不会被报告为成功，也不会与基础设施说明混淆。如果结果收集与 dispose（资源释放）都 reject，出错结果会保留两项失败。

+## 使用本包
 
-`backgroundMode` 同时选择后台路由与省略 `run_in_background` 时的默认行为。`one-shot` 默认在前台等待；显式传入 `true` 时，它会注册一个归父级所有的普通 Task，并返回规范值 `{ kind: 'background', jobId }`，渲染为 `started background subagent job <id>`，即使提供方支持可继续子 agent 也不例外。通用 Task 工具负责其后续状态、收集、取消和通知；失败 Task 的 detail 会保留终止原因与同一份可选提供方诊断。`continuable` 在参数省略或为 `true` 时于后台运行；显式传入 `false` 时则在前台等待结果。其后台路由要求提供方具备 `prepareContinuable` 能力，调用 `ctx.subagents.startContinuable()`，并返回 `{ kind: 'continuable', subagentId }`，渲染为 `started subagent <childId>`。该路由在 inbox 接受时结算：子 agent 自此拥有自己的轮次，因此该调用既不等待也不收集结果。通过该 id 查看其 transcript（文本记录）仍是其详细输出的来源，可选的全局 `send_message` 工具则向其发送更多工作。每当子 agent 的 Activation 结束，继续执行服务都会投递一条结算通知，其中包含结束结果及可能存在的最终 assistant 消息，且这项投递不依赖 `report`。启动可继续工作不要求加载 `send_message`。见[后台 subagent Agent Note](../../../.agents/notes/implemented/feature/2026-07-08-background-subagent-tasks.zh.md)、[可继续的 subagent Agent Note](../../../.agents/notes/implemented/feature/2026-07-28-continuable-subagent-conversations.zh.md)和[后台优先委派 Agent Note](../../../.agents/notes/implemented/feature/2026-08-11-background-first-continuable-delegation.zh.md)。
+每个委派目标挂载一个实例，且每个实例的 `toolName` 必须不同。工具与其提供方同时存在、同时消失，因此同级加载顺序与提供方重新加载都不会让工具悬空。
 
-`toolFilter` 会改变子 agent 的全局工具层，但不是从父级派生的权限上限。见 [agent 作用域的安全非目标](../../../.agents/notes/implemented/architecture/2026-07-08-agent-scope-contexts.zh.md#security-and-authority-are-non-goals)。
+### 最小配置
 
-## 配置
+先加载 subagent 服务、一个进程内或远程后端与本工具，然后指定提供方名称。此组合暴露一个委派给 `spawn` 后端的 `subagent` 工具：
 
-| 键 | 含义 |
+```yaml
+- name: '@deepseek-ai/dsh-subagent'
+- name: '@deepseek-ai/dsh-subagent-spawn-in-process'
+- name: '@deepseek-ai/dsh-tool-subagent'
+  config:
+    provider: spawn
+    toolName: subagent
+```
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `provider` | 必填 | `ctx.subagents` 上的提供方名称（如 `spawn`、`fork`、`acp`） |
+| `toolName` | `subagent` | 面向模型的工具名称；每个已加载实例必须不同 |
+| `enableModelSelection` | `false` | 静态公开子级 LLM 选择字段并注册 `list_subagent_models`；要求提供方支持 `agentOptions` |
+| `modelSelectionSettings` | `false` | 为每个新顶层 Session 读取宿主偏好；与 `enableModelSelection` 互斥，且只在 Agent 作用域内有效 |
+| `enableRunInBackground` | `true` | 公开 `run_in_background`；禁用时也会拒绝强制后台调用 |
+| `backgroundMode` | `one-shot` | 后台策略：`one-shot` 默认前台调用；`continuable` 默认后台调用，并要求提供方具备 `prepareContinuable` 能力 |
+| `agentOptions` | — | 配置的子级 `provider`、`model`、适配器所有的 `reasoningEffort` 与正整数 `maxTokens` 默认值；要求提供方支持 `agentOptions`，并会覆盖提供方持有的路由默认值 |
+| `persona` | — | 每个子 agent 独立的 persona；要求提供方具备 `persona` 能力 |
+| `toolFilter` | — | 每个子 agent 独立的全局工具限制；要求提供方具备 `toolFilter` 能力 |
+| `maxDepth` | `3` | 绝对委派深度上限（`0` 禁止委派）；`'provider-managed'` 不向进程外提供方发送上限 |
+
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-tool-subagent)是每个受支持字段及其 JSDoc 的穷尽式真源。
+
+### 前台与后台模式
+
+`one-shot` 策略下，省略 `run_in_background` 会在前台等待并返回子 agent 的最终文本；`run_in_background: true` 会启动一个归父级所有的普通后台任务，并返回 `started background subagent job <id>`，可用 `job_output` 收集、用 `job_kill` 停止。
+
+`continuable` 策略下，省略或为 `true` 的 `run_in_background` 会启动一个持久化子 agent，并返回 `started subagent <childId>`，不等待结果；子 agent 的 Activation 结束时，运行时投递一条结算通知，可选的 `send_message` 工具会向它发送更多工作。把 `run_in_background` 设为 `false` 可在前台等待结果。
+
+`maxDepth` 限制递归深度（默认 `3`；`0` 禁止委派），并要求提供方具备 `depthLimit` 能力；`'provider-managed'` 把预算留给进程外提供方。当提供方支持时，`persona` 与 `toolFilter` 会配置每个子 agent；工具在达到上限时仍然可见——每次尝试启动都会检查调用 agent 的当前深度，被拒绝时返回出错的工具结果。
+
+### 选择子级 LLM
+
+设置 `enableModelSelection: true` 可公开可选的 `provider`、`model` 与 `reasoning_effort` 字段，并注册共享的 `list_subagent_models` 工具。也可以设置 `modelSelectionSettings: true`，在组合每个顶层 Session 时读取宿主的 `subagent-model-selection.enabled` 偏好。该决定会记录进 Session、由子 Session 继承，后续设置编辑不会改变它。这两种模式互斥，且要求后端声明 `agentOptions`；ACP、Codex 与 Claude Code 会拒绝它们，DSH SDK 则支持路由选择。
+
+一次调用需同时提供 `provider` 与 `model`；当配置值、父 agent 值或提供方持有的默认值能提供路由时，也可只提供推理等级。静态的 `provider.agentRouteDefaults` 在存在时构成提供方／模型基线；工具配置与模型字段会在路由相关强度合并和确切路由预检前覆盖它。没有这些默认值的提供方会使用父 agent 最新已记录请求中的兼容值，再使用父级首次请求前的创建选项，并保留配置的 `maxTokens`。更改路由但未显式提供推理等级时，会清除继承的路由自有等级，使所选模型解析自己的默认值。实时 LLM 适配器在创建子 agent 前校验有效路由。目录成员资格只提供建议，因此适配器接受时，模型可以使用未列出的 id。

+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释工具如何镜像提供方生命周期并结算运行；可观察行为已在[使用本包](#use-this-package)中说明。
+
+### 设计理念
+
+一个实例就是一个提供方加一个工具名称。插件镜像提供方生命周期：具名提供方出现时注册工具，提供方离开时释放工具，因此同级加载顺序与 HMR 替换不会让工具悬空。提供方无法执行的数值型 `maxDepth` 或已配置 LLM 选择会在挂载时失败，而不是在首次委派时失败。每个工具作用域内最多一个实例可以拥有模型选择，因为 `list_subagent_models` 使用全局名称。
+
+### 前台结算
+
+前台调用会等待 `run.result`，把每个非完成终止原因映射为错误标题，追加提供方诊断与任何保留下来的部分 assistant 文本，并在返回前始终等待 `run.dispose()`；当结果收集与 dispose（资源释放）都 reject 时，出错结果会保留两项失败。
+
+### 后台路由
+
+一次性后台模式会注册一个归父级所有的普通 Task，其 done 通道结算启动，并在 detail 中保留终止原因与可选提供方诊断。可继续后台模式调用 `ctx.subagents.startContinuable()`，该调用在 inbox 接受时结算：子 agent 自此拥有自己的轮次，因此该调用既不等待也不收集结果。
+
+### 随上下文变化的措辞
+
+工具描述源自 `provider.inheritsParentContext`：全新子 agent 得到「it does not see this conversation」措辞，fork 子 agent 得到「it does not see the current in-flight turn」措辞，因此模型既不会复述、也不会省略并不存在的上下文。
+
+### 源码地图

-| `modelSelectionSettings` | 组合 Agent 时读取 Host 的 `subagent-model-selection` 偏好，把启用决定记录进其 Session，并让子 Session 继承该决定。默认为 `false`；与 `enableModelSelection` 互斥，且只能用于 Agent 作用域组合。该偏好默认关闭，只影响之后组合的新顶层 Session。 |
-| `enableRunInBackground` | 公开后台模式，默认 `true`；禁用时也会拒绝强制后台调用。 |
-| `backgroundMode` | 后台生命周期策略，默认 `one-shot`。`one-shot` 默认前台调用；`continuable` 默认后台调用，要求提供方具备 `prepareContinuable` 能力，并返回持久化子 agent ID，且不要求加载后续消息工具。 |

-## 并发
+</details>
 
-前台调用和后台调用均并发安全：同一条 assistant 消息中的同级委派会在循环的滚动池（`maxParallelToolCalls`）下重叠执行，结果仍按模型顺序提交。子 agent 在各自的会话中工作，一次运行绝不变更父会话；一次性后台形态对父级拥有状态的唯一写入是注册一个 Task——这是一次同步、可交换、能容忍并发分发的插入，因此重叠的后台调用按分发竞态顺序获得各自的 job id。协调同级工作区效果由模型负责，正如模型已经对后台和可继续子 agent 所承担的那样。见 [并行 subagent Agent Note](../../../.agents/notes/implemented/feature/2026-08-09-parallel-subagent-delegations.zh.md) 和 [并行工具调用 Agent Note](../../../.agents/notes/implemented/feature/2026-07-10-parallel-tool-call-execution.zh.md)。

 # subprocess/ — subprocess capability family
 
 English | [中文](README.zh.md)
 
-The shared process substrate for one execution world: executable lookup, fully-specified managed child-process trees with raw or collected stdio, and one deep terminal-process primitive that owns PTY allocation, foreground groups, and provider-observable session cleanup. Command defaulting, shell semantics, deadlines, protocol framing, readiness, and presentation stay with consumers — the [bash executors](../shell/README.md), [LSP host](../lsp/README.md), [PTY shell backend](../terminal/README.md), and [ACP subagent backend](../subagent/README.md). See the [subprocess seam Agent Note](../../.agents/notes/implemented/architecture/2026-07-26-subprocess-seam.md).
+## Summary
 
-| Package | ctx key | Role |
+Every child process and terminal session the harness runs — bash commands, language servers, persistent shells, and out-of-process subagent backends — starts, observes, and terminates through one shared service (`ctx.subprocess`), with a local provider running them on the host machine. It is not a standalone product feature: the consuming capability seams decide what each process means, and command semantics, deadlines, and model-facing presentation stay with them. The group provides executable lookup, bounded output capture with spill recovery, whole-tree termination, and a scrubbed starting environment for every child.

 English | [中文](README.zh.md)
 
-Local Service Provider for the [`@deepseek-ai/dsh-subprocess`](../subprocess/README.md) seam. `LocalSubprocessRuntime` resolves local executables, spawns ordinary detached process trees with explicit stdio, and implements terminal processes through `node-pty` plus platform process inspection. It has no config: every disposition, limit, terminal dimension, grace, and directory arrives from the calling capability seams ([`dsh-bash-local`](../../shell/bash-local/README.md), [`dsh-lsp-stdio`](../../lsp/lsp-stdio/README.md), and [`dsh-terminal-bash`](../../terminal/terminal-bash/README.md)).
+## Summary
 
-## Behavior
+Mount `dsh-subprocess-local` in any composition that runs child processes on the host: it resolves local executables, spawns detached process trees with explicit stdio, and provides real terminal sessions through `node-pty`. It has no configuration, so every disposition, limit, terminal size, and grace arrives on the spawn request from the calling capability seam. Output collection keeps a bounded in-memory tail with optional spill files for full-stream recovery, children start from a scrubbed environment, and disposal terminates and joins every running tree.
 
-- **Detached process trees with platform-correct signalling** — POSIX children are spawned `detached` (own process group) and signalled by negative pgid with a direct-child fallback; Windows terminates the tree via `taskkill /PID <pid> /T /F`. `terminate()` — the handle's only termination verb — sends SIGTERM then SIGKILL after the spec's grace (OpenCode's escalation; pipelines and subshells die with the parent) and is a no-op once the tree is gone; `waitForExit()` polls whole-tree liveness so consumer teardown confirms real quiescence. After the leader exits, still-open pipes receive the same bounded drain grace so a surviving descendant cannot hold the outcome open indefinitely. ESRCH is tolerated; daemons that re-parent away from the group can still survive.
-- **Per-stream dispositions** — `'pipe'` hands the raw stream to the caller untouched (protocol framing stays consumer-owned); `'inherit'` passes the parent descriptor through; collect mode keeps the in-memory TAIL beyond its cap (errors and results cluster at the end — pi/OpenCode rationale) while the FULL stream is appended to a private temp file when a spill cap is configured — omitting `spill` keeps only the tail, the diagnostic shape. A stream larger than the spill cap discards its now-incomplete spill and returns only the marked truncated tail; spill fds are sealed at settlement, and a failed final close withholds the path rather than advertising an incomplete file. Spill files are `0600` with random names under a lazily-created `0700` per-process directory.
-- **Credential scrub + explicit merge** — `process.env` minus credential-shaped vars (`*KEY*`/`*PASSWORD*`/`*SECRET*`/`*TOKEN*`) and all ambient `DSH_*` names; the spec's explicit `env` merges after that scrub with no namespace validation, so a deliberately supplied credential or current `DSH_*` fact wins while stale nested-harness identity cannot leak in ambiently. Supplied stdin is written and closed; otherwise fd 0 is `/dev/null`. See the [stdin/env Agent Note](../../../.agents/notes/implemented/architecture/2026-06-30-bash-stdin-env-trusted-plugin-api.md) and [managed environment Agent Note](../../../.agents/notes/implemented/feature/2026-07-10-agent-session-identity-and-log-location.md).
-- **Offset-based reads** — collect-mode readers return deltas in whole-stream byte coordinates; the service never holds a cursor, so consumer-owned cursors (the bash background read path) and full-stream re-reads coexist, before and after settlement.
-- **Executable lookup** — `resolveExecutable` checks absolute files or searches the scrubbed effective PATH with platform-aware executable extensions; relative paths containing separators are rejected at the seam, and relative PATH entries resolve from the host process cwd.
-- **Terminal-process ownership** — `spawnTerminal` allocates `node-pty`, bridges UTF-8 terminal text, inspects and signals the current foreground process group, and exposes one awaited termination operation that sweeps descendants before and after terminating the top-level shell. Linux reports an exact input wait only when the waiting thread's own fd 0 identifies the shell's controlling terminal, including the `/dev/tty` alias, so a pipeline reader blocked on `pipe:[…]` cannot publish terminal readiness. The syscall probe admits supported runtime architectures and matches every supported kernel ABI so user-mode emulation cannot hide the wait. When Linux denies `/proc/<pid>/task/<tid>/syscall`, the inspector reports no exact wait and leaves the higher PTY backend to its configured idle inference; process sleep state never substitutes for syscall evidence. Each foreground inspection retains exact identities from the rooted tree; Linux also enumerates the POSIX session after its leader exits. A previously observed macOS descendant and any same-session Linux member therefore remain fenced after reparenting, while pid/start identity prevents cleanup from following PID reuse. On Windows the koffi-backed inspector enumerates the process table through Toolhelp32, combines GetProcessTimes start identities with zero-time process-handle waits for liveness, reports the shell pid as the pseudo foreground group (Windows has no POSIX groups), and teardown verifies the shell's termination because externally taskkilled shells may never fire node-pty's exit notification. The higher PTY backend owns prompt readiness, buffers, and model-facing operations.
-- **Terminate-and-join disposal** — the service retains live handles so its own disposal can escalate every running tree and await its exit; quiescent and spawn-failed handles leave the live set after whole-tree or terminal-session cleanup finishes.
-- **Synchronous host-exit finalization** — while the service effect is active, a Node `exit` listener force-terminates every ordinary tree and observable terminal session still in the same live sets. The local-only operations send POSIX SIGKILL to the managed group, run Windows `taskkill /T /F`, and synchronously signal captured/current terminal identities around the PTY root kill; they create no promise or timer, preserve the host's exit code and diagnostic, contain each target's failure, and do not claim quiescence. Normal disposal keeps the awaited graceful path above. See the [host-exit cleanup decision](../../../.agents/notes/implemented/bug-fix/2026-08-11-synchronous-subprocess-exit-cleanup.md).

+## Use this package
+
+Mount the provider beside its consumers and start processes exactly as the subprocess service specifies; this package decides only how those processes run on the host.
+
+### Mounting the provider
+
+Load the provider in the same composition as its consumers. It has no config fields: every choice arrives on the spawn request, so deployment-varying decisions stay with the caller's configuration.
+
+```yaml
+- name: '@deepseek-ai/dsh-subprocess-local'
+- name: '@deepseek-ai/dsh-bash-local'
+```
+
+### Resolving executables
+
+Absolute executable paths are verified; bare names resolve against the scrubbed PATH with platform-aware executable extensions (`.COM`/`.EXE`/`.BAT`/`.CMD` on Windows). Relative paths containing separators are rejected — provide an absolute path or a bare PATH name — and relative PATH entries resolve from the host process cwd.
+
+### Collecting output
+
+Collect mode keeps the last `maxBytes` of a stream in memory — errors and final results cluster at the end — and, when a `spill` cap is configured, appends the complete stream to a private file under a per-process directory in the OS temp dir (a `0700` directory, `0600` random-named files). A stream larger than the spill cap discards its incomplete spill and returns only the marked truncated tail. Reads are offset-based and non-consuming, so background and batch readers coexist before and after exit.
+
+### Running terminal sessions
+
+`spawnTerminal` allocates a real PTY and bridges UTF-8 text; you can inspect and signal the current foreground process group and await a `terminate()` that settles every session member the provider can still observe. On Linux, an exact input wait requires a foreground thread whose fd 0 identifies the shell's controlling terminal and whose current syscall waits on that fd. If the kernel denies the syscall probe, the provider reports no exact wait and leaves the higher PTY backend to its idle inference; process sleep state is not evidence. On Windows, SIGINT is delivered as a Ctrl-C input write, SIGTSTP and SIGHUP are unsupported, and teardown verifies the shell's termination through the process table because an externally killed shell may never fire the PTY exit notification.
+
+### Shutdown behavior
+
+Normal disposal terminates every running tree and terminal and awaits their exit. During a JavaScript-observable host exit — direct `process.exit()`, default uncaught exceptions, default unhandled rejections — a synchronous finalization force-terminates everything still owned (SIGKILL to the group, `taskkill /T /F` on Windows) without creating promises or timers. Unhandled `SIGTERM`/`SIGINT`/`SIGHUP`, `SIGKILL`, fatal OOM, native crashes, and power loss need an external supervisor.
+
+### What can go wrong
+
+An executable that cannot be resolved fails loud with a stable error; a spawn that never starts rejects `done`. A read past the retained tail is `lossy` and points at the spill file when one exists. A daemonized descendant that leaves the tree or terminal session can outlive cleanup — see the limitations below.
+

+
+<a id="understand-the-implementation"></a>
+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the provider and points at the code that realizes them; the observable behavior is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The provider treats the process tree as the unit of lifetime. POSIX children spawn detached (their own process group) so the whole tree is signalled by negative group id with a direct-child fallback; Windows terminates by root pid through `taskkill /T`. Signalling, escalation, and teardown guard on tree liveness rather than direct-child settlement, so a TERM-trapping helper cannot outlive the handle unnoticed.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Service wiring: live-handle sets, disposal, host-exit finalization, executable lookup |
+| [`src/spawn.ts`](src/spawn.ts) | Process plumbing: detached spawn, tail-keep collection, spill files, escalation, tree-exit observer |
+| [`src/terminal.ts`](src/terminal.ts) | `node-pty` terminal handle: foreground inspection, session cleanup, Windows teardown |
+| [`src/process-inspector.ts`](src/process-inspector.ts) | POSIX process-tree and session inspection |
+| [`src/windows-inspector.ts`](src/windows-inspector.ts) | Windows Toolhelp32 process-table inspection via koffi |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; the seam owns the contract) |
+
+### Main flow
+
+A spawn builds the scrubbed child environment, starts the detached process, attaches collectors to the collected streams, and returns a handle. `done` settles at process close after a bounded pipe-drain grace, so a surviving descendant that inherited a pipe cannot hold the outcome open indefinitely; the escalation timer survives direct-child settlement so SIGKILL still reaches tree survivors. Terminal cleanup sweeps descendants by exact identity, stops the shell, re-sweeps, and verifies absence through the process table.
+
+### Safety invariants
+
+Spill files are opened `0600` with `O_EXCL` and random names under a `0700` per-process directory, defeating symlink planting in shared temp dirs; a failed final close withholds the spill path. Process identities carry start times, so cleanup never follows PID reuse. Host-exit finalization creates no promises or timers, preserves the host exit code and diagnostic, contains each target's failure, and does not claim quiescence.

-- **Windows tree support is best-effort** — termination routes through `taskkill /PID <pid> /T /F` with all outcomes contained (absent tree, races, missing binary), and liveness falls back to the direct-child boundary.
-- **Windows terminal signalling is console-wide** — SIGINT is delivered as a `\x03` Ctrl-C input write that conhost turns into a console-wide CTRL_C event; SIGTSTP and SIGHUP are rejected as unavailable; a `taskkill` without `/F` does not terminate console processes, so the teardown TERM tier is a grace wait before the `/F` escalation. Windows readiness has no exact stdin-wait tier: the prompt-marker fast path compares the shell pid as the pseudo foreground group, and silence/timing tiers cover the rest.
-- **A daemonized terminal descendant can still escape the observable boundary** — on macOS, a child that reparents before any foreground-inspection snapshot is no longer discoverable from the `node-pty` root; on Linux, a child that calls `setsid` leaves both the tree and owned terminal session. The local provider does not add a continuous process-table monitor.
-- **In-process cleanup requires a JavaScript-observable exit** — direct `process.exit()`, default uncaught exceptions, and default unhandled rejections emit Node's synchronous `exit` event. The default OS disposition for an unhandled `SIGTERM`, `SIGINT`, or `SIGHUP` bypasses that event; an application covers those signals only by installing a handler that performs normal disposal or calls `process.exit()`. `SIGKILL`, fatal OOM, `process.abort()`, native crashes, power loss, and any failure that cannot run JavaScript require an external supervisor, container init, or equivalent OS owner.
-- **The credential scrub is a name heuristic** — `*KEY*`/`*PASSWORD*`/`*SECRET*`/`*TOKEN*` only; differently-named secrets (e.g. `*PASSPHRASE*`) pass through, and a whitelist for over-scrubbed vars is noted future work.
-- **Completed spill files are not deleted** — bounded full-output recovery files (and the private per-process spill dir) accumulate under the OS tmpdir until something external cleans them; oversize incomplete spills are discarded and deletion is attempted immediately, but a cleanup failure can leave a bounded file behind.

+在需要于宿主机上运行子进程的组合中挂载 `dsh-subprocess-local`：它解析本地可执行文件、以显式 stdio 运行 detached 进程树，并通过 `node-pty` 提供真实终端会话。它没有任何配置，因此每项处置方式、限制、终端尺寸与宽限期都随 spawn 请求来自调用方能力 seam。输出收集在内存中保留一段有界尾部，并可选地用 spill 文件恢复完整流；子进程从清理后的环境起步；dispose（资源释放）会终止并等待每棵仍在运行的进程树退出。
 
-- **以适合平台的方式发送信号的 detached 进程树**：POSIX 子进程使用 `detached` spawn（拥有独立进程组），信号以负 pgid 发送并以直接子进程作为回退；Windows 通过 `taskkill /PID <pid> /T /F` 终止进程树。`terminate()`（句柄唯一的终止操作）先发送 SIGTERM，经过 spec 的宽限期后再发送 SIGKILL（沿用 OpenCode 的升级策略；流水线与子 shell 会随父进程一起结束），进程树消亡后为空操作；`waitForExit()` 轮询整棵进程树的存活状态，使消费方的拆卸能确认真正的完全停稳。组长进程退出后，仍然打开的管道也只获得同样有界的排空宽限期，因此存活的后代进程无法无限期地拖住结果不结算。系统会容忍 ESRCH；重新指定父进程并脱离该组的 daemon 仍可能存活。
-- **按流划分的处置方式**：`'pipe'` 把原始流原样交给调用方（协议分帧仍归消费方所有）；`'inherit'` 直通父进程的描述符；收集模式（collect）在输出超过上限后于内存中保留尾部（错误与结果通常聚集在末尾，沿用 pi/OpenCode 的理由），并在配置了 spill 上限时把完整流追加到一个私有临时文件；省略 `spill` 则只保留用于诊断的尾部。某条流大于 spill 上限时，会丢弃已不完整的 spill，仅返回带截断标记的尾部；spill 文件描述符在结算时封存，最终关闭失败时则不公布路径，以免声称存在不完整的文件。spill 文件权限为 `0600`、名称随机，位于按需创建、权限为 `0700` 的每进程目录之下。
-- **凭据清除 + 显式合并**：以 `process.env` 为基础，移除形似凭据的变量（`*KEY*`／`*PASSWORD*`／`*SECRET*`／`*TOKEN*`）和所有环境中已有的 `DSH_*` 名称；spec 的显式 `env` 在该清除之后合并且不做命名空间校验，因此有意提供的凭据或当前 `DSH_*` 事实会胜出，而陈旧的嵌套 harness 身份无法从环境中隐式漏入。提供的 stdin 会被写入后关闭；否则 fd 0 指向 `/dev/null`。参见 [stdin/env Agent Note](../../../.agents/notes/implemented/architecture/2026-06-30-bash-stdin-env-trusted-plugin-api.zh.md)与[受管环境 Agent Note](../../../.agents/notes/implemented/feature/2026-07-10-agent-session-identity-and-log-location.zh.md)。
-- **基于偏移量的读取**：收集模式的读取器按完整流的字节坐标返回增量；服务自身从不持有游标，因此消费方自有的游标（bash 的后台读取路径）与完整流重读可以共存，结算前后皆然。
-- **可执行文件查找**：`resolveExecutable` 检查绝对文件，或根据平台可执行文件扩展名在清理后的有效 PATH 中搜索；含分隔符的相对路径在该 seam 处被拒绝，相对 PATH 条目从宿主进程 cwd 解析。
-- **终端进程所有权**：`spawnTerminal` 分配 `node-pty`，桥接 UTF-8 终端文本，检查当前前台进程组并向其发送信号，还会公开一项须等待的终止操作，在终止顶层 shell 前后清理后代进程。Linux 只有在等待线程自身的 fd 0 标识 shell 的控制终端（包括 `/dev/tty` 别名）时才报告精确输入等待，因此阻塞于 `pipe:[…]` 的流水线读取端无法发布终端就绪状态。syscall 探针会准入受支持的运行时架构并匹配每个受支持的内核 ABI，使用户态模拟无法隐藏该等待。当 Linux 拒绝读取 `/proc/<pid>/task/<tid>/syscall` 时，检查器不会报告精确等待，而是由上层 PTY 后端按配置执行 idle 推断；进程休眠状态绝不会代替 syscall 证据。每次前台检查都会保留根进程树中的精确身份；Linux 还会在 POSIX 会话 leader 退出后枚举该会话。因此，之前观察到的 macOS 后代以及同会话 Linux 成员在重新设定父进程后仍受围栏保护，pid/start 身份则防止清理跟随 PID 复用。在 Windows 上，基于 koffi 的检查器通过 Toolhelp32 枚举进程表，把 GetProcessTimes 启动身份与进程句柄零时等待结合起来判断存活状态，并把 shell pid 作为伪前台进程组（Windows 没有 POSIX 进程组）。拆卸会验证 shell 已终止，因为被外部 taskkill 的 shell 可能永远不会触发 node-pty 的退出通知。上层 PTY 后端负责提示符就绪、缓冲区与面向模型的操作。
-- **先终止再等待退出的 dispose（资源释放）**：服务保留存活句柄，使自身的 dispose 能对每个仍在运行的进程树执行升级并等待其退出；完全停稳与 spawn 失败的句柄会在整棵进程树或 terminal session 清理完成后离开存活集合。
-- **同步宿主退出最终清理**：服务 effect 仍有效时，Node `exit` listener 会强制终止同一组存活集合中仍存在的每棵普通进程树和可观察 terminal session。这些仅供本地实现使用的操作会向受管 POSIX 进程组发送 SIGKILL、在 Windows 运行 `taskkill /T /F`，并在终止 PTY root 前后同步向已捕获及当前可观察的 terminal 身份发送信号；它们不会创建 Promise 或 timer，不改变宿主退出码与诊断，会分别包含每个目标的失败，也不会声称已经完全停稳。正常 dispose 仍使用上面的须等待温和路径。参见[宿主退出清理决策](../../../.agents/notes/implemented/bug-fix/2026-08-11-synchronous-subprocess-exit-cleanup.zh.md)。

+## 使用本包
+
+把提供方与它的消费方挂载在同一组合中，并完全按子进程服务的规定启动进程；本包只决定这些进程在宿主机上如何运行。
+
+### 挂载提供方
+
+在与消费方相同的组合中加载本提供方。它没有任何配置字段：每项选择都随 spawn 请求到达，因此随部署变化的决策留在调用方的配置里。
+
+```yaml
+- name: '@deepseek-ai/dsh-subprocess-local'
+- name: '@deepseek-ai/dsh-bash-local'
+```
+
+### 解析可执行文件
+
+绝对可执行文件路径会被验证；裸名称根据清理后的 PATH 并以平台感知的可执行文件扩展名（Windows 上为 `.COM`/`.EXE`/`.BAT`/`.CMD`）解析。含分隔符的相对路径会被拒绝——请提供绝对路径或裸 PATH 名称——相对 PATH 条目从宿主进程 cwd 解析。
+
+### 收集输出
+
+收集模式在内存中保留一条流的最后 `maxBytes`——错误与最终结果通常聚集在末尾——并在配置了 `spill` 上限时把完整流追加到 OS 临时目录下每进程目录中的私有文件（`0700` 目录、`0600` 随机命名文件）。某条流大于 spill 上限时，会丢弃不完整的 spill，只返回带截断标记的尾部。读取基于偏移量且从不消费，因此后台读取与批量读取在退出前后都可以共存。
+
+### 运行终端会话
+
+`spawnTerminal` 分配真实 PTY 并桥接 UTF-8 文本；你可以检查当前前台进程组并向其发送信号，还可以等待一次 `terminate()`，让提供方仍可观察到的每个会话成员完全停稳。在 Linux 上，精确输入等待要求前台线程的 fd 0 标识 shell 的控制终端，且线程当前的 syscall 正在等待该 fd。如果内核拒绝 syscall 探测，提供方不会报告精确等待，而由上层 PTY 后端使用空闲推断；进程睡眠状态不能作为证据。在 Windows 上，SIGINT 以 Ctrl-C 输入写入投递，SIGTSTP 与 SIGHUP 不受支持，拆卸会通过进程表验证 shell 已终止，因为被外部终止的 shell 可能永远不会触发 PTY 退出通知。
+
+### 关闭行为
+
+正常 dispose 会终止每棵仍在运行的进程树与终端并等待其退出。在 JavaScript 可观察的宿主退出期间——直接 `process.exit()`、默认未捕获异常、默认未处理 rejection——同步最终清理会强制终止所有仍归本包所有的对象（对进程组发送 SIGKILL，Windows 上运行 `taskkill /T /F`），且不创建任何 Promise 或定时器。未处理的 `SIGTERM`/`SIGINT`/`SIGHUP`、`SIGKILL`、fatal OOM、native crash 与断电则需要外部 supervisor。
+
+### 可能出错的地方
+
+无法解析的可执行文件会以稳定的错误快速失败；从未启动成功的 spawn 会让 `done` reject。越过保留尾部的读取是 `lossy` 的，并在 spill 文件存在时指向它。脱离进程树或终端会话的 daemon 化后代可能比清理更长寿——见下文限制。

+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释提供方背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中说明。
+
+### 设计理念
+
+本提供方把进程树视为生命周期单元。POSIX 子进程以 detached 方式 spawn（拥有独立进程组），因此整棵进程树以负进程组 id 发送信号，并以直接子进程作为回退；Windows 通过 `taskkill /T` 按根 pid 终止。信号发送、升级与拆卸都以进程树存活状态为守卫，而非以直接子进程结算为准，因此拦截 TERM 的辅助进程无法在无人察觉的情况下比句柄更长寿。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 服务接线：存活句柄集合、dispose、宿主退出最终清理、可执行文件查找 |
+| [`src/spawn.ts`](src/spawn.ts) | 进程管道：detached spawn、保尾收集、spill 文件、升级、进程树退出观察器 |
+| [`src/terminal.ts`](src/terminal.ts) | `node-pty` 终端句柄：前台检查、会话清理、Windows 拆卸 |
+| [`src/process-inspector.ts`](src/process-inspector.ts) | POSIX 进程树与会话检查 |
+| [`src/windows-inspector.ts`](src/windows-inspector.ts) | 经 koffi 的 Windows Toolhelp32 进程表检查 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；约定归 seam 所有） |
+
+### 主流程
+
+一次 spawn 会构建清理后的子进程环境、启动 detached 进程、把收集器挂到收集模式的流上，然后返回句柄。`done` 在进程关闭后、经过一段有界管道排空宽限期才结算，因此继承了管道的存活后代无法无限期拖住结果；升级定时器在直接子进程结算后依然存活，使 SIGKILL 仍能到达进程树幸存者。终端清理按精确身份清扫后代、停止 shell、再次清扫，并通过进程表验证其已不存在。
+
+### 安全不变式
+
+spill 文件以 `0600` 权限、`O_EXCL` 与随机名称在 `0700` 每进程目录下创建，可抵御共享临时目录中的符号链接植入；最终关闭失败时不公布 spill 路径。进程身份携带启动时间，因此清理绝不会跟随 PID 复用。宿主退出最终清理不创建 Promise 或定时器，保留宿主退出码与诊断，分别包含每个目标的失败，也不会声称已经完全停稳。

-The subprocess seam (`ctx.subprocess`) is the process half of one execution world. The abstract `SubprocessRuntime` exposes executable lookup, ordinary managed `spawn`, and one terminal-process primitive; its vocabulary covers raw/collected stdio, process and terminal handles, exit facts, tree/session cleanup, and the managed `DSH_*` environment namespace. The local implementation lives in [`dsh-subprocess-local`](../subprocess-local/README.md).
+## Summary
 
-## Contract
+Any composition that runs child processes can start a fully specified child process or a real terminal session through `ctx.subprocess`, receive a live handle with streams and exit facts, and terminate the whole process tree on demand. The service provides executable lookup, the shared environment scrub, and bounded output capture, while every default — argv, deadlines, shell semantics — stays explicit on the request, so the consuming capability seams decide what a process means. A composition mounts one provider implementation (such as `dsh-subprocess-local`) that registers the service; the seam package itself is an abstract contract, not a loadable plugin. Nothing here reaches a model directly: process output and lifecycle are rendered by the consuming tools.
 
-- `spawn(spec)` returns immediately with a live handle; `done` resolves at process close with exit facts (`SubprocessOutcome` carries no output and no cause classification) and rejects only for spawn-level failures.
-- Spawn working directories and executable paths belong to the provider's execution world. `resolveExecutable(command, env?, signal?)` verifies absolute commands or resolves bare names against that world's scrubbed PATH plus explicit overrides.
-- The spec is fully explicit — argv, cwd, per-stream stdio dispositions, grace — because deployment-varying defaults belong to the caller's config, not to a hidden subprocess-service default (the `dsh-shell` request/spec split is the owning template). `argv` is never shell-interpreted; a consumer that wants a shell passes `['bash', '-c', command]` itself.
-- Stdio is Node-shaped per stream: `'pipe'` hands the caller the raw stream for its own protocol framing (LSP JSON-RPC, ACP ndjson), `'inherit'` passes the parent descriptor through for diagnostics, and collect mode (`{ maxBytes, spill? }`) buffers a bounded tail with an optional full-stream spill file. Collect readers take whole-stream byte offsets and never consume, so independent readers cannot steal one another's deltas; a read whose offset slid out of the in-memory tail is `lossy` and points at the spill file when one exists. Collected output stays readable after settlement.
-- Termination is tree-scoped on every platform (POSIX detached groups with direct-child fallback; Windows `taskkill /T`): `terminate()` — the only termination verb — escalates SIGTERM→grace→SIGKILL (idempotent, driven by the spec's abort signal too, a no-op once the tree is gone), and `waitForExit(signal?)` observes whole-tree liveness so a consumer-owned teardown ladder holds each tier on real quiescence — the manager reacts but never classifies why (callers own deadlines, teardown ladders, and cause classification).
-- `spawnTerminal(spec)` is the only non-pipe primitive. Its handle owns a real PTY, UTF-8 text I/O, foreground-process-group inspection/signalling, and one awaited `terminate()` operation that reaches quiescence for every session member the provider can still observe and settles in-flight handle calls; providers document substrate-specific observability limits. The spec signal cancels allocation only; the published handle owns its lifetime. The output stream ends after queued output when the top-level process exits, and a live transport failure rejects `done`. These operations remain one substrate primitive because ordinary pipes cannot allocate a controlling terminal or clean terminal-session members; readiness, scrollback, and owner policy remain in the PTY consumer.
-- `scrubbedParentEnv()` / `SENSITIVE_ENV_PATTERN` are the one shared scrub definition: ambient credential-shaped and `DSH_*` names are dropped, and explicit `env` merges after the scrub. The local ordinary and terminal spawns both apply it; SDK-managed transports that own their spawn may import it directly.
-- Disposal of the service terminates all still-running managed processes and awaits their exit.

+## Use this package
+
+Mount a subprocess provider in any composition that must run child processes, and call `ctx.subprocess` from the capability that owns the command. The common path is explicit: resolve the executable, spawn with a fully specified request, read the output you asked for, and terminate the tree when the work is done.
+
+### Mounting the service
+
+One provider registers `ctx.subprocess` per composition; load it beside the consumers that spawn through it — the bash executors, the LSP host, the PTY shell backend, or an out-of-process subagent backend. Loading a second provider fails loudly (one service per context, cordis standard).
+
+```yaml
+- name: '@deepseek-ai/dsh-subprocess-local'
+- name: '@deepseek-ai/dsh-bash-local'
+```
+
+### Starting a managed process
+
+The request is fully explicit: the program and arguments, the working directory, one stdio disposition per stream, a termination grace, an optional abort signal, and optional environment overrides. `done` resolves with exit facts (`exitCode` and `signal`) when the process closes and rejects only for spawn-level failures; collected output stays readable after exit.
+
+```text
+const executable = await ctx.subprocess.resolveExecutable('bash')
+const handle = ctx.subprocess.spawn({
+  argv: [executable, '-c', 'echo hello'],
+  cwd: '/workspace',
+  stdio: { stdin: 'ignore', stdout: { maxBytes: 64 * 1024 }, stderr: 'inherit' },
+  graceMs: 5000,
+})
+const { exitCode, signal } = await handle.done
+const output = handle.collected.stdout?.readFrom(0)
+```
+
+### Choosing how output is delivered
+
+- `'pipe'` hands you the raw stream for your own protocol framing — JSON-RPC for the LSP host, ndjson for the ACP backend.
+- `'inherit'` lets the child write to the parent's own stream, for pass-through diagnostics.
+- A collect object buffers a bounded in-memory tail; add a `spill` cap and the complete stream is also recoverable from a spill file.
+
+Reads are offset-based and non-consuming: a background reader and a final batch read can share one stream without stealing each other's bytes.
+
+### Managing process lifetime
+
+Termination is tree-scoped everywhere: `terminate()` escalates SIGTERM → grace → SIGKILL (Windows force-terminates immediately), is idempotent, and is a no-op once the tree is gone. The request's abort signal starts the same escalation, so a consumer-owned deadline can cancel a whole tree. `waitForExit()` resolves only when the entire tree has exited, not just the direct child, so a still-running helper is observable before teardown returns. Callers own deadlines and cause classification; the service only reacts.
+
+### Running a terminal session
+
+For interactive programs, `spawnTerminal` allocates a real PTY: write text, read UTF-8 output, inspect and signal the current foreground process group, and await one `terminate()` that settles every session member the provider can still observe. Readiness, scrollback, and prompt policy stay with the PTY consumer.
+
+### Environment every child starts from
+
+Children never inherit the harness's ambient secrets: credential-shaped names and ambient `DSH_*` facts are scrubbed, and the caller's explicit `env` merges after that scrub. A deliberately forwarded credential or a current `DSH_*` deployment fact still reaches the child; an explicit `undefined` tombstone removes an ordinary ambient entry.
+
+### What can go wrong
+
+An executable that cannot be resolved fails loud with a stable error. A spawn that never starts rejects `done`; there is no buffered output for a process that never ran. A daemonized child that leaves its tree or session can outlive termination — provider READMEs document their observability limits. When a transport owns its own spawn (the SDK client, MCP), route around the service and import `scrubbedParentEnv` directly so environment policy stays single-sourced.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the seam and points at the code that realizes them; the observable behavior is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The seam is built on one separation: the service owns process coordinates and lifetime; consumers own what a process means and every default that shapes one. That is why the spawn request is fully explicit — no hidden subprocess-service default — and why `SubprocessOutcome` carries exit facts only: callers own deadlines, teardown ladders, and cause classification. The `dsh-shell` request/spec split is the owning template.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: abstract `SubprocessRuntime`, `ctx.subprocess` registration, the shared `scrubbedParentEnv` scrub |
+| [`src/types.ts`](src/types.ts) | Vocabulary: spawn spec, stdio modes, handles, readers, outcomes, `DSH_*` namespace |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; providers own observations) |
+
+### Data model and flow
+
+A spawn returns a live handle immediately; the request's abort signal drives the same termination escalation as `terminate()`. Collected readers are cursor-free: offsets are whole-stream byte coordinates the caller owns, so independent readers cannot consume one another's output, and a read whose offset slid out of the in-memory tail is `lossy` and points at the spill file when one exists. `spawnTerminal` is one deep primitive because ordinary pipes cannot allocate a controlling terminal or clean terminal-session members.
+
+### Lifecycle and invariants
+
+One implementation registers per context; loading a second throws (cordis standard). Disposal of the service terminates every still-running managed process and awaits its exit, so process lifetime survives consumer reloads. `argv` is never shell-interpreted; a consumer that wants a shell passes `['bash', '-c', command]` itself. Terminal allocation cancellation (the spec signal) is separate from the published handle's lifetime.

 # @deepseek-ai/dsh-subprocess
 
 [English](README.md) | 中文
 
-子进程 seam（`ctx.subprocess`）是一个执行世界的进程部分。抽象的 `SubprocessRuntime` 公开可执行文件查找、普通受管 `spawn` 和一项终端进程原语；其词汇涵盖原始／收集式 stdio、进程与终端句柄、退出事实、进程树／会话清理，以及受管的 `DSH_*` 环境命名空间。本地实现位于 [`dsh-subprocess-local`](../subprocess-local/README.zh.md)。
+## 概述
 
-## 约定
+任何需要运行子进程的组合都可以通过 `ctx.subprocess` 启动完全明确指定的子进程或真实终端会话，收到带流与退出事实的活动句柄，并按需终止整棵进程树。本服务提供可执行文件查找、共享的环境清理与有界输出捕获，而每一项默认值——argv、时限、shell 语义——都显式留在请求上，由消费方能力 seam 决定进程的含义。组合只需挂载一个提供方实现（如 `dsh-subprocess-local`）来注册该服务；seam 包本身是抽象约定，不是可直接加载的插件。本包不直接接触模型：进程输出与生命周期的渲染由消费方工具负责。
 
-- `spawn(spec)` 立即返回一个活动句柄；`done` 在进程关闭时以退出事实 resolve（`SubprocessOutcome` 不携带输出，也不携带原因分类），仅在 spawn 层面失败时 reject。
-- spawn 工作目录和可执行文件路径属于提供方的执行世界。`resolveExecutable(command, env?, signal?)` 验证绝对命令，或根据该执行世界清理后的 PATH 加显式覆盖来解析裸名称。
-- spec 完全显式（argv、cwd、按流划分的 stdio 处置方式（disposition）、宽限期），因为随部署变化的默认值属于调用方的配置，而不属于某个隐藏的子进程服务默认值（`dsh-shell` 的 request/spec 拆分是这条规则的所属模板）。`argv` 绝不经过 shell 解释；需要 shell 的消费方自行传入 `['bash', '-c', command]`。
-- stdio 按流采用 Node 风格：`'pipe'` 把原始流交给调用方做自己的协议分帧（LSP 的 JSON-RPC、ACP（Agent Client Protocol）的 ndjson），`'inherit'` 直通父进程描述符以承载诊断输出，收集模式（collect）`{ maxBytes, spill? }` 则缓冲一段有界尾部，外加可选的完整流 spill 文件。收集模式的读取器接受全流字节偏移量且从不消费，因此独立的读取器不会抢走彼此的增量；偏移量滑出内存尾部窗口的读取标记为 `lossy`，并在 spill 文件存在时指向它。收集到的输出在结算后仍可读取。
-- 终止在每个平台上都以进程树为范围（POSIX 用 detached 进程组并以直接子进程回退；Windows 用 `taskkill /T`）：`terminate()`（唯一的终止动词）执行 SIGTERM→宽限期→SIGKILL 升级（幂等，也由 spec 的 abort 信号驱动，进程树消亡后为空操作）；`waitForExit(signal?)` 观察整棵进程树的存活状态，使消费方自有的拆卸阶梯能在真正完全停稳后才进入下一层。管理器只响应中止，但绝不判定原因（deadline、拆卸阶梯与原因分类归调用方所有）。
-- `spawnTerminal(spec)` 是唯一的非管道原语。其句柄负责真实 PTY、UTF-8 文本 I/O、前台进程组检查／信号发送，以及一项须等待的 `terminate()` 操作；该操作会使提供方仍可观察到的每个会话成员完全停稳，并结算在途句柄调用；提供方会记录执行基底特有的可观察性限制。spec 信号只取消分配；句柄一经发布，便负责自身生命周期。顶层进程退出时，输出流在已排队输出之后结束；仍处于活动状态的传输若发生故障，会使 `done` 拒绝。这些操作保留为一项执行基底原语，因为普通管道无法分配控制终端或清理终端会话成员；就绪状态、scrollback 和所有者策略仍归 PTY 消费方所有。
-- `scrubbedParentEnv()` / `SENSITIVE_ENV_PATTERN` 是唯一一份共享的环境清理定义：环境中形似凭据的名称与 `DSH_*` 名称都会被丢弃，显式 `env` 在清除之后合并。本地的普通 spawn 与终端 spawn 都应用该定义；拥有自身 spawn 的 SDK 管理传输可直接导入它。
-- 服务自身的 dispose（资源释放）会终止所有仍在运行的受管进程并等待其退出。

+## 使用本包
+
+在需要运行子进程的组合中挂载一个 subprocess 提供方，并从拥有该命令的能力包调用 `ctx.subprocess`。常用路径是显式的：解析可执行文件、用完全明确的请求 spawn、读取你要的输出，并在工作完成时终止进程树。
+
+### 挂载服务
+
+每个组合由唯一一个提供方注册 `ctx.subprocess`；把它与经由它 spawn 的消费方放在一起加载——bash 执行器、LSP 主机、PTY shell 后端或进程外 subagent 后端。加载第二个提供方会快速失败（每个上下文只有一个服务，这是 cordis 的标准行为）。
+
+```yaml
+- name: '@deepseek-ai/dsh-subprocess-local'
+- name: '@deepseek-ai/dsh-bash-local'
+```
+
+### 启动受管进程
+
+请求完全明确：程序与参数、工作目录、每条流一种 stdio 处置方式、终止宽限期、可选的中止信号与可选的环境覆盖。进程关闭时，`done` 以退出事实（`exitCode` 与 `signal`）resolve，且只在 spawn 层面失败时 reject；收集输出在退出后仍可读取。
+
+```text
+const executable = await ctx.subprocess.resolveExecutable('bash')
+const handle = ctx.subprocess.spawn({
+  argv: [executable, '-c', 'echo hello'],
+  cwd: '/workspace',
+  stdio: { stdin: 'ignore', stdout: { maxBytes: 64 * 1024 }, stderr: 'inherit' },
+  graceMs: 5000,
+})
+const { exitCode, signal } = await handle.done
+const output = handle.collected.stdout?.readFrom(0)
+```
+
+### 选择输出投递方式
+
+- `'pipe'` 把原始流交给你做自己的协议分帧——LSP 主机用 JSON-RPC，ACP 后端用 ndjson。
+- `'inherit'` 让子进程直接写父进程自己的流，用于直通诊断输出。
+- collect 对象缓冲一段有界的进程内尾部；加上 `spill` 上限后，完整流还可以从 spill 文件中恢复。
+
+读取基于偏移量且从不消费：后台读取与最终批量读取可以共享同一条流，而不会抢走彼此的字节。
+
+### 管理进程生命周期
+
+终止在任何平台上都以进程树为范围：`terminate()` 执行 SIGTERM → 宽限期 → SIGKILL 升级（Windows 上立即强制终止），幂等，进程树消亡后为空操作。请求的中止信号会启动同样的升级，因此消费方自有的 deadline 可以取消整棵进程树。`waitForExit()` 只有在整棵进程树都退出后才会 resolve，而非只看直接子进程，因此在拆卸返回之前仍可观察到仍在运行的辅助进程。时限与原因分类归调用方所有；服务只做响应。
+
+### 运行终端会话
+
+对于交互式程序，`spawnTerminal` 分配真实 PTY：写入文本、读取 UTF-8 输出、检查当前前台进程组并向其发送信号，以及等待一次 `terminate()`，让提供方仍可观察到的每个会话成员完全停稳。就绪状态、scrollback 与提示符策略仍归 PTY 消费方所有。
+
+### 每个子进程起步时的环境
+
+子进程永远不会隐式继承 harness 的环境秘密：形似凭据的名称与环境中的 `DSH_*` 事实都会被清除，调用方显式的 `env` 在该清除之后合并。有意转发的凭据或当前的 `DSH_*` 部署事实仍会到达子进程；显式的 `undefined` 墓碑值则移除一个普通的环境项。
+
+### 可能出错的地方
+
+无法解析的可执行文件会以稳定的错误快速失败。从未启动成功的 spawn 会让 `done` reject；从未运行过的进程没有任何缓冲输出。脱离进程树或会话的 daemon 化子进程可能比终止更长寿——提供方 README 会记录各自的可观察性限制。当传输拥有自己的 spawn（SDK 客户端、MCP）时，请绕开本服务并直接导入 `scrubbedParentEnv`，让环境策略保持单一来源。

+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释 seam 背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中说明。
+
+### 设计理念
+
+本 seam 建立在一个分离之上：服务负责进程坐标与生命周期；消费方负责定义进程的含义，以及决定塑造该进程的每一项默认值。正因如此，spawn 请求完全明确——没有任何隐藏的子进程服务默认值——`SubprocessOutcome` 也只携带退出事实：时限、拆卸阶梯与原因分类归调用方所有。`dsh-shell` 的 request/spec 拆分是这条规则的所属模板。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：抽象 `SubprocessRuntime`、`ctx.subprocess` 注册、共享的 `scrubbedParentEnv` 清除 |
+| [`src/types.ts`](src/types.ts) | 词汇：spawn spec、stdio 模式、句柄、读取器、结果、`DSH_*` 命名空间 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；观察由提供方负责） |
+
+### 数据模型与流程
+
+spawn 立即返回活动句柄；请求的中止信号驱动与 `terminate()` 相同的终止升级。收集模式的读取器无游标：偏移量是调用方拥有的全流字节坐标，因此独立读取器不会消费彼此的输出，偏移量滑出内存尾部的读取标记为 `lossy`，并在 spill 文件存在时指向它。`spawnTerminal` 是一项底层原语，因为普通管道无法分配控制终端或清理终端会话成员。
+
+### 生命周期与不变式
+
+每个上下文只注册一个实现；加载第二个会抛错（cordis 标准行为）。服务自身的 dispose（资源释放）会终止所有仍在运行的受管进程并等待其退出，因此进程生命周期在消费方重载后依然延续。`argv` 绝不经过 shell 解释；需要 shell 的消费方自行传入 `['bash', '-c', command]`。终端分配的取消（spec 信号）与已发布句柄的生命周期相互独立。

+
 - **Windows-only native loading** — importing the generic types is portable, but resolving the binding table loads Windows DLLs and fails on other hosts. Cross-platform tests inject a binding table instead of loading native APIs.
 - **No public process service** — the package intentionally does not wrap its primitives in Cordis or Node streams. A consumer must own its policy, async scheduling, output limits, cancellation, and final handle closure.
 - **Inherited environment only** — process creation passes a null environment block. The sandbox establishes changes through `SetEnvironmentVariableW` first because passing an explicit block through Koffi makes `CreateProcessAsUserW` fail with `ERROR_INVALID_PARAMETER`. Other callers that need environment changes must establish them before invoking the primitive or use their own runner process.
 - **Restricted-token consumer only** — ordinary `CreateProcessW`, exact `applicationName`, parent-stdio release, and whole-Job settlement are absent until an ordinary process consumer requires them.
 - **Create-to-assignment interruption** — the target starts suspended and cannot execute before Job assignment, but an external termination of the runner in the narrow interval between process creation and assignment can leave the suspended target behind. The package does not claim atomic Job attachment.
 - **Header evidence is architecture-specific** — the committed ABI probe and layout constants cover the repository's current 64-bit Windows targets. A new pointer width or incompatible Windows ABI requires updating the probe before support is claimed.

 - **仅在 Windows 原生加载** — 导入通用类型可跨平台进行，但解析绑定表会加载 Windows DLL，并在其他宿主失败。跨平台测试注入绑定表，不加载原生 API。

 - **只继承环境** — 进程创建传入空环境块。sandbox 会先通过 `SetEnvironmentVariableW` 建立改动，因为经 Koffi 传入显式环境块会使 `CreateProcessAsUserW` 以 `ERROR_INVALID_PARAMETER` 失败。其他需要改写环境的调用方必须在调用原语前建立环境，或使用自己的 runner 进程。

 # terminal/ — persistent PTY capability family
 
 English | [中文](README.zh.md)
 
-`PTY` stands for **pseudo-terminal**. This capability provides persistent, owner-scoped terminal sessions for workflows that require state across tool calls or interactive stdin. PTY complements the one-shot bash and filesystem tools; it does not replace their stronger per-operation contracts.
+## Summary
+
+The `terminal/` group gives agents persistent, owner-scoped terminal sessions: shell and REPL state — cwd, exported variables, activated environments, running interactive children — survives across tool calls. Three packages cover the family: `terminal/` provides the owner-scoped session service behind `ctx.terminals` (sessions get opaque ids, and every operation stays fenced to the owning agent); `terminal-bash/` starts an interactive bash or pwsh shell under the shared sandbox policy; and `tool-terminal/` exposes six model-facing tools with bounded results. A terminal complements the one-shot bash and filesystem tools: use it when work needs interactive stdin or cross-call state. Sessions are process-local and do not survive a harness restart.

 # terminal/：持久 PTY 能力家族
 
 [English](README.md) | 中文
 
-`PTY` 的全称是 **pseudo-terminal（伪终端）**。这项能力提供持久且限定所有者范围的终端会话，适用于需要跨工具调用保留状态或使用交互式 stdin 的工作流。PTY 是单次 bash 与文件系统工具的补充，不会取代后两者更严格的逐操作约定。
+## 概述
 
-| 包 | 职责 | ctx 键 |
+`terminal/` 组为 agent 提供持久且限定所有者范围的终端会话：shell 与 REPL 状态——cwd、导出的变量、激活的环境、正在运行的交互式子进程——都能跨工具调用存活。三个包共同覆盖整个家族：`terminal/` 提供限定所有者范围的 `ctx.terminals` 会话服务（会话获得不透明 id，每个操作都限制在所属 agent 内）；`terminal-bash/` 在共享沙箱策略下启动交互式 bash 或 pwsh shell；`tool-terminal/` 提供 6 个结果有界的面向模型工具。终端是单次 bash 与文件系统工具的补充：仅在需要交互式 stdin 或跨调用状态时使用。会话只存在于进程本地，harness 重启后不会恢复。

 # @deepseek-ai/dsh-terminal-bash
 
 English | [中文](README.zh.md)
 
-Persistent shell backend for `ctx.terminals` over `ctx.subprocess.spawnTerminal`. It starts an interactive shell under the shared `ctx.sandboxPolicy`, retains bounded line-oriented output, and detects readiness while the subprocess provider owns PTY allocation, environment scrubbing, foreground process groups, signalling, and complete terminal-session cleanup. The same PTY backend therefore composes with local or remote execution-world providers.
+## Summary
 
-## Plugin (`terminal-bash`)
+`dsh-terminal-bash` starts a persistent interactive shell under the deployment's sandbox policy: the session stays alive across tool calls, readiness for input is detected, and bounded line-oriented output is retained for reads. It provides the `shell` backend type and supports bash on POSIX and pwsh on Windows through a `shellDialect` setting. The same backend composes with local or remote execution worlds through the mounted subprocess provider. Full-screen terminal applications are outside its line-oriented contract.
 
-The plugin injects `pty`, `sandboxPolicy`, and `subprocess`, then registers the configured backend type (`shell`). `danger-full-access` starts the shell directly without requiring a sandbox provider; confined modes require a same-world `ctx.sandbox` and wrap the exact shell argv through it, failing before spawn when none is mounted. At spawn, one `ctx.sandboxPolicy.resolve({ session })` call supplies both the effective mode and the session workspace root; the same root is the default shell cwd when the caller omits one. A change to a different effective mode is rejected before its `sandbox/mode` event commits while that owner has an open PTY or a spawn in progress; the fence is attached to the exact owner and therefore outlives a provider reload that retains existing sessions. Wait for creation to settle and close the sessions before changing modes, so a terminal opened with wider access cannot survive a downgrade.
+## Table of Contents
 
-`shellDialect` selects the shell stack (`bash` default, `pwsh`): it picks the default `shellPath`/`shellArgs` (bash `--noprofile --norc -i`; pwsh `-NoLogo -NoProfile` through the shared `dsh-pwsh-local` resolver) and the startup contract. The bash dialect installs its prompt through the environment (`PS1` plus an OSC `133;D;`-terminated `PROMPT_COMMAND`). pwsh cannot install a prompt from the environment, so the backend writes a `prompt` function through the session and accepts startup only after the backend reports `stdin_read`; echoed setup text cannot publish the shell. One `timeoutMs` deadline starts before the complete pwsh startup loop, so an `inferred_idle` follow-up send does not restart the bound. Its environment drops the bash-only markers and adds `NO_COLOR`, while the first send prefixes the shared `dsh-pwsh-local` encoding preamble, pinning `[Console]::OutputEncoding` and `$OutputEncoding` to UTF-8 before anything runs. A zero-scrollback `@xterm/headless` instance consumes the raw PTY stream and writes terminal-protocol replies, including cursor-position reports required by Unix pwsh, through the same terminal handle. The backend drains those replies before every caller input and samples foreground state only after the protocol state stayed quiet throughout inspection. It keeps one parser write active and coalesces later raw chunks into the next batch, so high-volume output does not schedule one parser task per chunk. The line-oriented sanitizer and bounded buffers remain the only output projection. Both dialects emit the same BEL-terminated OSC marker, so the readiness machinery and consumers are dialect-agnostic.

-Readiness combines a foreground-verified private bash prompt marker, provider-reported foreground stdin-wait facts, silence fallback, and absolute timeout. A marker is not ready until the printable tail after the latest owned marker exactly equals the controlled `PS1`, including when the OSC marker and prompt are split across data callbacks; echoed input or output following an earlier prompt therefore cannot settle the current send. The controlled `PROMPT_COMMAND` re-asserts that `PS1` before every prompt, so an in-shell prompt override cannot degrade later sends to silence readiness. Prompt and silence evidence collected before the provider write, including while pre-write foreground inspection is pending, is discarded at the write boundary. When bash prints the marker before the terminal provider publishes its return to the foreground process group, polling retains the candidate for `handoffGraceMs` past the ordinary silence bound so a coincident handoff can win. An interactive child that inherits `PROMPT_COMMAND` therefore cannot suppress inferred-idle readiness until the absolute timeout. Unknown foreground state is never a positive exact-idle signal. A foreground group's stdin wait that existed before a send is likewise not post-write readiness: the same group must be observed outside that wait before a later wait can settle the send, while a changed foreground group is new evidence. During unpublished startup, a fallback requires observed output; zero-output silence cannot publish an empty session, and timeout rejects the spawn. Cancellation closes the unpublished shell and rejects with the caller's exact abort reason; `TerminalBackendCleanupError` separately preserves a cleanup failure. The caller's signal is forwarded for terminal allocation and readiness initialization; after publication the handle owns its lifetime. Incomplete terminal-control sequences are bounded by `maxReadBytes` and discarded through their terminator after crossing that limit; malformed UTF-8 terminal output uses replacement characters, and a trailing carriage return is carried across callbacks so split CRLF becomes one newline.
+-----
 
-Send cancellation marks queued input as canceled before asking the terminal handle to signal the current foreground process group with a real `SIGINT`; if asynchronous pre-write inspection later settles, it cannot execute that input. If a provider write is already in flight, signalling waits for it to settle; a rejected write sends no signal. The canceled send retains its slot until the write and foreground signalling settle, so a successor cannot receive either late bytes or that signal. A provider write or signal that never settles therefore retains the slot indefinitely; closing the session (`terminal_close`) is the recovery. The absolute deadline remains armed while cancellation waits. A signal failure is a terminal transport failure and rejects the active send. Cancellation never emulates interruption by writing `\x03`, so raw-mode programs remain cancellable. Close rejects new public signals, stops readiness polling, and awaits the handle's provider-owned complete-session termination before settling the active send as `session_exit`.
+<a id="use-this-package"></a>
+## Use this package
 
+Mount this backend when a composition needs persistent shell sessions — state such as cwd, exported variables, functions, or running interactive children must survive across tool calls. It is the default `shell` type: a composition that mounts `@deepseek-ai/dsh-terminal` without it has no sessions to open.
+
+### When to choose it
+
+Choose this backend when work needs an interactive shell or REPL whose state persists: stepping a debugger, exploring in a Python or Node REPL, or returning to a shell after interrupting a foreground command. Choose the one-shot bash tool for bounded commands that should start and end in one call. The bash dialect targets POSIX; the pwsh dialect targets Windows hosts where `dsh-pwsh-local` can resolve a pwsh executable.
+
+### Composition
+
+Mount the terminal service, a subprocess provider, the sandbox and policy services, this backend, and a tool package:
+
+```yaml
+- name: '@deepseek-ai/dsh-terminal'
+- name: '@deepseek-ai/dsh-subprocess-local'
+- name: '@deepseek-ai/dsh-sandbox-local'
+- name: '@deepseek-ai/dsh-sandbox-policy'
+- name: '@deepseek-ai/dsh-terminal-bash'
+- name: '@deepseek-ai/dsh-tool-terminal'
+```
+
+`danger-full-access` starts the shell directly. Confined modes require a same-world `ctx.sandbox` provider: without one, the spawn fails before the shell starts.
+
+### Configuration
+
+| Field | Default | Meaning |
+|---|---|---|
+| `backendType` | `shell` | Backend type registered on `ctx.terminals` |
+| `shellDialect` | `bash` | Interactive shell stack: `bash` or `pwsh` |
+| `shellPath` / `shellArgs` | per dialect | Shell executable and arguments; empty selects the dialect defaults |
+| `maxReadBytes` | `262144` | Maximum UTF-8 bytes returned by one read or settled send |
+| `timeoutMs` | `30000` | Absolute bound on one send wait |
+| `disposeGraceMs` | `3000` | Grace before teardown escalates to `SIGKILL` |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-terminal-bash) is the exhaustive source for every field, including the readiness timings (`pollIntervalMs`, `exactProbeAfterMs`, `idleSilenceMs`, `handoffGraceMs`), terminal size (`rows`, `cols`), and scrollback bounds (`scrollbackLines`, `scrollbackMaxBytes`).
+
+### Shell dialects and readiness
+
+Both dialects expose the same readiness contract, so consumers are dialect-agnostic. A send settles when the shell is ready again: after the controlled prompt is verified, after the foreground process group provably waits on stdin (Linux), after output silence (`inferred_idle`), or at the absolute `timeoutMs`. An `inferred_idle` or `timeout` result does not prove the foreground command exited.
+
+### Sandboxing and safe operation
+
+The shell runs under the effective sandbox boundary for its whole life. Changing the effective sandbox mode is rejected while the owner still has open sessions or a spawn in progress — wait for creation to settle and close the sessions first, so a terminal opened with wider access cannot survive a downgrade. The backend supplies only terminal-specific environment overrides; the subprocess provider applies its shared credential scrub.
+
+### Observable outcomes and failures
+
+An open returns the session id and a bounded startup message. Sends settle with one of the four wait reasons and a session status; `session_exit` means the top-level shell exited. Setup failures reject the open: a missing sandbox provider in a confined mode, a shell that exits during startup, a shell that fails to reach readiness before the startup timeout, or caller cancellation. Cleanup failures reject the close instead of claiming success.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design behind the backend and points at the code that realizes it; the observable behavior is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+One backend serves both dialects: bash and pwsh share the same session machinery — sanitizer, bounded buffers, readiness polling, cancellation, and teardown — and differ only in argv, environment, and prompt installation. Bash receives a private marker through `PS1` plus `PROMPT_COMMAND`. Pwsh writes a prompt function, pins UTF-8 console encoding, and publishes startup only after the backend reports `stdin_read`; echoed setup text cannot publish the shell. A zero-scrollback `@xterm/headless` instance consumes raw PTY data and returns terminal-protocol replies through the same handle, while the line sanitizer remains the only output projection.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Backend registration, sandbox-mode fence, argv and environment assembly, startup sequence |
+| [`src/config.ts`](src/config.ts) | Dialect resolution, defaults, and validation of every timing field |
+| [`src/session.ts`](src/session.ts) | `LocalPtySession`: send lifecycle, readiness polling, scrollback, signals, close |
+| [`src/sanitize.ts`](src/sanitize.ts) | Streaming control-sequence sanitizer and line normalization |
+
+### Readiness model
+
+Three bounded tiers settle a send: exact stdin-wait evidence from the subprocess provider (Linux only), the verified private prompt marker with an exact printable tail, and output silence (`inferred_idle`); an absolute timeout always bounds the wait. Pwsh startup uses one deadline across its complete setup loop, so an `inferred_idle` follow-up does not restart the bound. Evidence collected before the provider write is discarded at the write boundary, a stdin wait that predates the write is not post-write readiness, and unknown foreground state is never a positive exact-idle signal.
+
+### Send cancellation and teardown
+
+Cancellation marks queued input as canceled, then signals the current foreground process group with a real `SIGINT` after any in-flight provider write settles; it never emulates interruption by writing `\x03`. Closing stops readiness polling, terminates the provider-owned process tree, awaits quiescence, and settles the active send as `session_exit`.
+
+### Sandbox-mode fence
+
+A write that would change the effective sandbox mode is rejected before the `sandbox/mode` event commits while that owner has an open session or a spawn in progress. The fence is attached to the exact owner and outlives a provider reload that retains existing sessions.

 ## Known Limitations and Deferred Work
 
-- A headless xterm instance maintains control-sequence state only for terminal-protocol replies. Returned output remains line-oriented and normalized; full-screen alternate-buffer interaction is unsupported.
-- Exact stdin-wait detection depends on the mounted subprocess provider; providers that cannot prove it use prompt-marker and silence/timeout readiness. Windows is such a provider: the shell pid is the pseudo foreground group and there is no exact stdin-wait tier, so a marker-less child settles on the silence bound.
-- The pwsh bootstrap writes through `[Console]::` (the UTF-8 encoding pin and the prompt function), which the Windows ACL sandbox's read-only mode (ConstrainedLanguage) may deny. When that prevents marker readiness, startup rejects at `timeoutMs` instead of publishing a shell whose setup did not complete.
-- Cleanup guarantees are those of `SubprocessTerminalHandle`; provider-specific gaps belong to that implementation's contract rather than this PTY consumer.
-- Sessions do not survive harness process exit.
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define where the backend is a poor fit or needs special operational care. They are current package constraints, not a general shell comparison or a task backlog.
+
+- **Line-oriented output only** — a headless xterm maintains control-sequence state only for terminal-protocol replies. Returned output remains normalized to lines, and full-screen alternate-buffer interaction is unsupported.
+- **Readiness is heuristic without an exact tier** — exact stdin-wait detection depends on the mounted subprocess provider; providers that cannot prove it (macOS, Windows) settle on prompt-marker and silence/timeout readiness.
+- **pwsh bootstrap in a constrained sandbox** — the prompt function and UTF-8 pin write through `[Console]::`, which the Windows ACL sandbox's read-only mode may deny. When that prevents marker readiness, startup rejects at `timeoutMs` instead of publishing an incomplete shell.
+- **Cleanup guarantees belong to the provider** — process-tree teardown is the `SubprocessTerminalHandle` contract, not this backend's.

-这是一个基于 `ctx.subprocess.spawnTerminal`、为 `ctx.terminals` 提供的持久 shell 后端。它在共享 `ctx.sandboxPolicy` 下启动交互式 shell，保留有界的逐行输出并检测就绪状态；进程管理提供方则负责 PTY 分配、环境清理、前台进程组、信号发送和完整终端会话清理。因此，同一个 PTY 后端可以与本地或远程执行世界提供方组合。
+## 概述
 
-## 插件（`terminal-bash`）
+`dsh-terminal-bash` 在部署的沙箱策略下启动持久交互式 shell：会话跨工具调用存活，检测 shell 何时可以接收输入，并保留有界的逐行输出供读取。它提供 `shell` 后端类型，并通过 `shellDialect` 设置在 POSIX 上支持 bash、在 Windows 上支持 pwsh。通过已挂载的子进程提供方，同一个后端既可以与本地执行世界组合，也可以与远程执行世界组合。全屏终端应用不在其逐行约定的范围内。
 
-该插件注入 `pty`、`sandboxPolicy` 和 `subprocess`，然后注册所配置的后端类型（`shell`）。`danger-full-access` 无需沙箱提供方即可直接启动 shell；受限模式要求同一执行世界中存在 `ctx.sandbox`，并通过它包装确切的 shell argv，未挂载时会在 spawn 前失败。spawn 时，一次 `ctx.sandboxPolicy.resolve({ session })` 调用会同时给出实际模式与会话工作区根目录；调用方省略 cwd 时，同一根目录也是 shell 的默认 cwd。当某个所有者存在开放的 PTY 或正在进行 spawn 时，如果配置变更会得到不同的实际模式，系统会在对应 `sandbox/mode` 事件提交前拒绝该变更。该限制绑定到确切所有者，因此即使提供方重新加载并保留现有会话，它仍然有效。更改模式前，请等待创建完成并关闭会话，避免以更宽权限打开的终端在权限降级后继续存在。

-`shellDialect` 选择 shell 栈（默认 `bash`，或 `pwsh`）：它决定默认的 `shellPath`／`shellArgs`（bash 为 `--noprofile --norc -i`；pwsh 经共享的 `dsh-pwsh-local` 解析器得到 `-NoLogo -NoProfile`）与启动契约。bash 方言通过环境安装提示符（`PS1` 加 OSC `133;D;` 终结的 `PROMPT_COMMAND`）。pwsh 无法从环境安装提示符，因此后端通过会话写入 `prompt` 函数，并且只在后端报告 `stdin_read` 后才接受启动；回显的引导文本不能发布 shell。系统会在完整的 pwsh 启动循环之前启动一条 `timeoutMs` 绝对超时计时器，因此 `inferred_idle` 后续 send 不会重新计时。其环境去掉 bash 专属标记并加 `NO_COLOR`，同一条首发送还会带上共享的 `dsh-pwsh-local` 编码前缀，在一切运行之前把 `[Console]::OutputEncoding` 与 `$OutputEncoding` 钉为 UTF-8。一个不保留 scrollback 的 `@xterm/headless` 实例会消费原始 PTY 流，并通过同一终端句柄写回终端协议响应，包括 Unix pwsh 所需的光标位置报告。后端会在每次调用方输入前排空这些响应，并且只使用协议状态在整次检查期间保持静止后采样的前台状态。它只保留一个活跃 parser 写入，并把后来到达的原始 chunk 合并为下一批，因此高输出量不会为每个 chunk 分别调度 parser 任务。逐行 sanitizer 与有界缓冲区仍是唯一的输出投影。两种方言发出相同的 BEL 终结 OSC 标记，因此就绪机制与消费方与方言无关。

-就绪检测结合以下机制：由前台状态验证的私有 bash 提示符标记、提供方报告的前台 stdin 等待事实、静默回退和绝对超时。只有最新自有标记之后的可打印尾部与受控 `PS1` 完全相等，标记才算就绪；即使 OSC 标记和提示符被拆到多个数据回调中也一样。因此，较早提示符之后的回显输入或输出无法使当前 send 完成。受控 `PROMPT_COMMAND` 会在每次输出提示符前重新设定该 `PS1`，因此在 shell 内覆盖提示符不会使后续 send 退化到静默就绪。提供方写入前收集的提示符与静默证据，包括写入前前台检查仍在等待时收集的证据，都会在写入边界丢弃。如果 bash 在终端提供方发布其重新取得前台进程组的状态前打印标记，轮询会在普通静默上限之后再保留该候选状态 `handoffGraceMs`，使恰好同时发生的前台交接有机会胜出。因此，继承 `PROMPT_COMMAND` 的交互式子进程无法一直抑制推断空闲就绪直至绝对超时。未知的前台状态绝不会作为精确空闲的正向信号。同样，一次 send 之前就已存在的前台进程组 stdin 等待并不代表写入后就绪：必须先观察到同一进程组脱离该等待，之后再次进入等待才能使该次 send 完成；前台进程组发生变化则构成新的证据。尚未发布的启动过程中，回退路径要求已经观察到输出；零输出静默不能发布空会话，超时则拒绝 spawn。取消操作会关闭尚未发布的 shell，并以调用方提供的确切中止原因拒绝；`TerminalBackendCleanupError` 会单独保留清理失败。调用方的 signal 会转发给终端分配与就绪初始化；发布后，句柄负责其生命周期。未完成的终端控制序列受 `maxReadBytes` 限制；超过上限后，系统会丢弃内容直到其终止符。格式错误的 UTF-8 终端输出使用替换字符；末尾的回车会跨回调保留，使拆分的 CRLF 合并为一个换行。
+-----
 
-取消发送时，系统会先把排队输入标记为已取消，再要求终端句柄向当前前台进程组发送真正的 `SIGINT`；异步写入前检查即使随后结算，也无法执行该输入。如果提供方写入已在途，信号发送会等待其结算；写入被拒绝时不会发送信号。已取消的 send 会保留其位置，直到写入与前台信号发送都结算，因此后继 send 不会收到延迟字节或该信号。因此，永不结算的提供方写入或信号会无限期保留该位置；恢复手段是关闭会话（`terminal_close`）。取消等待期间，绝对 deadline 仍保持启用。信号发送失败是终端传输失败，会拒绝活跃 send。取消绝不会通过写入 `\x03` 模拟中断，因此，即使程序运行在 raw 模式下，也仍可取消。关闭操作会拒绝新的公开信号、停止就绪轮询，并等待由句柄提供方负责的完整会话终止，然后才把活跃 send 结算为 `session_exit`。

+## 使用本包
 
+当组合需要持久 shell 会话时挂载此后端——cwd、导出的变量、函数或正在运行的交互式子进程等状态必须跨工具调用存活。它是默认的 `shell` 类型：组合只挂载 `@deepseek-ai/dsh-terminal` 而不挂载它时，将没有任何会话可打开。
+
+### 何时选择
+
+当工作需要状态持续存在的交互式 shell 或 REPL 时选择此后端：逐步调试 gdb、在 Python 或 Node REPL 中探索，或中断前台命令后回到 shell。对于应当一次调用即开始并结束的有界命令，请选择单次 bash 工具。bash 方言面向 POSIX；pwsh 方言面向 `dsh-pwsh-local` 能解析出 pwsh 可执行文件的 Windows 主机。
+
+### 组合方式
+
+挂载终端服务、子进程提供方、沙箱与策略服务、此后端以及一个工具包：
+
+```yaml
+- name: '@deepseek-ai/dsh-terminal'
+- name: '@deepseek-ai/dsh-subprocess-local'
+- name: '@deepseek-ai/dsh-sandbox-local'
+- name: '@deepseek-ai/dsh-sandbox-policy'
+- name: '@deepseek-ai/dsh-terminal-bash'
+- name: '@deepseek-ai/dsh-tool-terminal'
+```
+
+`danger-full-access` 直接启动 shell。受限模式要求同一执行世界中存在 `ctx.sandbox` 提供方：缺少时，spawn 会在 shell 启动前失败。
+
+### 配置
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `backendType` | `shell` | 注册到 `ctx.terminals` 的后端类型 |
+| `shellDialect` | `bash` | 交互式 shell 栈：`bash` 或 `pwsh` |
+| `shellPath` / `shellArgs` | 按方言 | shell 可执行文件与参数；为空时选择方言默认值 |
+| `maxReadBytes` | `262144` | 一次读取或一次结算发送返回的最大 UTF-8 字节数 |
+| `timeoutMs` | `30000` | 一次发送等待的绝对上限 |
+| `disposeGraceMs` | `3000` | 清理升级到 `SIGKILL` 前的宽限时间 |
+
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-terminal-bash)是每个字段的穷尽式真源，包括就绪计时（`pollIntervalMs`、`exactProbeAfterMs`、`idleSilenceMs`、`handoffGraceMs`）、终端尺寸（`rows`、`cols`）与 scrollback 上限（`scrollbackLines`、`scrollbackMaxBytes`）。
+
+### shell 方言与就绪
+
+两种方言暴露相同的就绪约定，因此消费方与方言无关。当 shell 再次就绪时发送即结算：受控提示符被验证之后、前台进程组被证明在等待 stdin（Linux）之后、输出静默（`inferred_idle`）之后，或到达绝对 `timeoutMs`。`inferred_idle` 或 `timeout` 结果并不证明前台命令已退出。
+
+### 沙箱与安全运行
+
+shell 在整个生命周期内运行在有效的沙箱边界之下。当所有者仍有打开的会话或进行中的 spawn 时，改变有效沙箱模式会被拒绝——请先等待创建完成并关闭会话，避免以更宽权限打开的终端在权限降级后继续存在。后端只提供终端专属的环境覆盖；共享凭据清理由子进程提供方负责。
+
+### 可观察结果与失败
+
+打开会返回会话 id 与有界启动消息。发送以四种等待原因之一与一个会话状态结算；`session_exit` 表示顶层 shell 已退出。设置失败会拒绝打开：受限模式下缺少沙箱提供方、shell 在启动期间退出、shell 未能在启动超时前达到就绪，或调用方取消。清理失败会拒绝关闭，而不是声称成功。

+
+本节解释后端背后的设计并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中说明。
+
+### 设计理念
+
+一个后端服务两种方言：bash 与 pwsh 共享同一套会话机制——清理器、有界缓冲区、就绪轮询、取消与关闭——只在 argv、环境与提示符安装方式上不同。bash 通过 `PS1` 加 `PROMPT_COMMAND` 接收私有标记。pwsh 会写入提示符函数、钉住 UTF-8 控制台编码，并只在后端报告 `stdin_read` 后发布启动；回显的设置文本不能发布 shell。一个不保留 scrollback 的 `@xterm/headless` 实例会消费原始 PTY 数据，并通过同一句柄返回终端协议响应；逐行 sanitizer 仍是唯一输出投影。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 后端注册、沙箱模式限制、argv 与环境组装、启动序列 |
+| [`src/config.ts`](src/config.ts) | 方言解析、默认值与每个计时字段的校验 |
+| [`src/session.ts`](src/session.ts) | `LocalPtySession`：发送生命周期、就绪轮询、scrollback、信号、关闭 |
+| [`src/sanitize.ts`](src/sanitize.ts) | 流式控制序列清理器与行规范化 |
+
+### 就绪模型
+
+三个有界档位结算一次发送：来自子进程提供方的精确 stdin 等待证据（仅 Linux）、带精确可打印尾部的受控私有提示符标记，以及输出静默（`inferred_idle`）；绝对超时始终限制等待。pwsh 启动的完整设置循环共用一条 deadline，因此 `inferred_idle` 后续发送不会重新计时。提供方写入前收集的证据会在写入边界丢弃，早于写入的 stdin 等待不算写入后就绪，未知的前台状态绝不是精确空闲的正向信号。
+
+### 发送取消与关闭
+
+取消先把排队输入标记为已取消，再在任何在途的提供方写入结算后向当前前台进程组发送真正的 `SIGINT`；它绝不会通过写入 `\x03` 模拟中断。关闭会停止就绪轮询、终止提供方拥有的进程树、等待完全停稳，并把活跃发送结算为 `session_exit`。
+
+### 沙箱模式限制
+
+当所有者存在打开的会话或进行中的 spawn 时，凡是会改变有效沙箱模式的写入都会在 `sandbox/mode` 事件提交前被拒绝。该限制绑定到确切所有者，并在保留现有会话的提供方重新加载后依然有效。

-Owner-scoped persistent PTY seam. `TerminalSessionService` registers as `ctx.terminals`, mints opaque session ids, routes creation through named backends, fences every operation to the exact live `Agent`, and awaits backend quiescence when that agent or the service disposes.
+## Summary
 
-## Contract
+`dsh-terminal` provides persistent, owner-scoped terminal sessions to the harness: a session keeps shell or REPL state across tool calls, and every operation is fenced to the exact agent that created it. It provides the `ctx.terminals` service, which mints opaque session ids, routes session creation through registered backends, and waits for quiescent cleanup when an owner or the service disposes. It defines no terminal mechanics itself: backends such as the shipped `dsh-terminal-bash` own spawning and readiness, and the model-facing tools in `dsh-tool-terminal` own presentation. Sessions are process-local: they do not survive a harness restart.
 
-- Backends register one stable `type` and return an unpublished `TerminalBackendSession`; failed or cancelled setup must clean partial resources, and a failed cleanup rejects with `TerminalBackendCleanupError` so the registry can retain it across cancellation.
-- Spawn cancellation preserves the caller's exact abort reason. Service disposal and owner loss remain distinct machine-routable failures after backend setup.
-- Owner and service disposal abort unpublished setup through a service-owned signal and await backend settlement plus rollback before returning.
-- A rollback-close or backend-reported startup cleanup failure rejects the disposing lifecycle instead of claiming quiescence. Caller-triggered cancellation still receives its exact reason; lifecycle-triggered rollback failure also rejects the pending spawn.
-- A backend cleanup failure that follows caller cancellation remains owner activity until owner or service disposal consumes and reports it, so lifecycle policy cannot mistake failed cleanup for quiescence.
-- `hasOwnerActivity(owner)` spans unpublished setup through final close, so lifecycle policy can fence the exact owner without a publication race.
-- A successful spawn publishes one `TerminalSessionId`. The optional `name` is owner-local display metadata, never authority.
-- One session accepts at most one live send operation. Reads and signals may observe it; another send fails until the operation settles.
-- `TerminalSendResult.waitReason` and `sessionStatus` are independent. `session_exit` describes the top-level PTY process, not an arbitrary foreground command.
-- `kill()` and disposal resolve only after the backend's captured process tree is quiescent. A cleanup failure rejects instead of claiming success and clears the matching backend and registry fences so a later close can retry without disturbing a newer attempt.

+## Use this package
+
+Mount `@deepseek-ai/dsh-terminal` whenever a composition needs terminal sessions whose state survives across tool calls. The service alone does nothing useful: pair it with a backend such as `@deepseek-ai/dsh-terminal-bash` and a tool package such as `@deepseek-ai/dsh-tool-terminal`, and load all three in one composition.
+
+### When to choose it
+
+Choose persistent terminals for work whose state lives in the terminal rather than a file: stepping a debugger, exploring in a Python or Node REPL, or returning to a shell after interrupting its foreground command. Choose the one-shot bash, read, write, and edit tools for bounded operations — they keep stronger validation, approval, output-bound, and replay contracts. Sessions are process-local: they disappear when the harness process exits, so durable work belongs in files or another persistent system.
+
+### Composition
+
+Load the session service together with a backend and a tool package:
+
+```yaml
+- name: '@deepseek-ai/dsh-terminal'
+- name: '@deepseek-ai/dsh-terminal-bash'
+- name: '@deepseek-ai/dsh-tool-terminal'
+```
+
+A backend provides one stable type — the shipped shell backend provides `shell` — and the tools open sessions by that type. The shell backend additionally requires the sandbox, sandbox-policy, and subprocess providers; see its [README](../terminal-bash/README.md) for the full composition.
+
+### What sessions give you
+
+Once a session exists, consumers can open a session and receive its id and bounded startup output, send text (optionally submitting Enter) and wait until the shell is ready again or the send times out, read bounded retained output, deliver one allowed signal to the foreground process group, close a session and wait for its process tree to end, and list the sessions a caller owns. Exactly one send can be active per session at a time; a second send fails until the first settles.
+
+### Ownership and isolation
+
+Every session is owned by the exact agent that opened it. Operations that name a session are rejected when the caller is not that agent, so the model cannot reach another agent's terminal even if it learns the id. An optional session `name` is owner-local display metadata — labels such as `main` or `gdb` — and is unique only within its owner.
+
+### Observable outcomes and failures
+
+A successful open returns the session id, type, pid when the backend has one, status, and a bounded startup message. Sends settle with a wait reason: `stdin_read` (the shell is waiting for input), `inferred_idle` (output silence), `timeout`, or `session_exit` (the top-level shell exited). Failures carry stable machine-routable codes: a missing backend type (`NO_BACKEND`), an unknown session (`NO_SESSION`), another agent's session (`FOREIGN_SESSION`), a second concurrent send (`SEND_ACTIVE`), or an owner that is no longer live (`OWNER_NOT_LIVE`). Backend setup failures reject the open before anything is published, and a failed cleanup rejects the close rather than claiming success.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design behind the service and points at the code that realizes it; the observable behavior is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The service owns everything except terminal mechanics: session identity, publication, authorization, and cleanup. Backends own how a session starts, detects readiness, retains output, and shuts down; the service publishes a session only after backend setup succeeds. The split keeps one registry usable with different terminal substrates.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | `TerminalSessionService`: backend registry, spawn/send/read/signal/kill/list, owner cleanups, disposal |
+| [`src/types.ts`](src/types.ts) | Shared contracts: backend interface, session types, wait reasons, signal set, error codes |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; the registries are private mutable state) |
+
+### Data model and lifecycle
+
+Each published session is a record of its id, owner, optional name, backend type, and backend session, plus the one active send. Unpublished spawns are tracked per owner as reservations with a service-owned abort signal. Disposal aborts pending spawns, awaits their settlement and rollback, then closes every owned session and awaits quiescence before running owner detachers; a cleanup failure rejects the lifecycle instead of claiming success.
+
+### Ownership and cleanup rules
+
+- Fencing uses the exact `Agent` object: `hasOwnerActivity(owner)` spans unpublished setup through final close with no publication gap, so lifecycle policy can fence the owner precisely.
+- A backend that cannot clean partial startup resources rejects with `TerminalBackendCleanupError`; the service retains that failure as tracked owner activity until owner or service disposal consumes and reports it.
+- Caller cancellation keeps its exact `AbortSignal.reason`; `kill()` and disposal resolve only after the backend's captured process tree is quiescent.
+
+### Send reservation
+
+The service reserves a session synchronously for one active send before returning the operation, including before a background job id becomes visible; a second send fails with `SEND_ACTIVE`, so output and cancellation never cross operation ownership.

-限定所有者范围的持久 PTY seam。`TerminalSessionService` 注册为 `ctx.terminals`，生成不透明的会话 id，通过具名后端路由创建操作，将每个操作限制在完全相同的活跃 `Agent` 内，并在该 agent（智能体）或服务 dispose（资源释放）时等待后端完全停稳。
+## 概述
 
-## 约定
+`dsh-terminal` 为 harness 提供持久且限定所有者范围的终端会话：会话让 shell 或 REPL 状态跨工具调用存活，且每个操作都被限制在创建它的那个确切 agent（智能体）内。本包提供 `ctx.terminals` 服务，负责生成不透明的会话 id、通过已注册的后端路由会话创建，并在所有者或服务 dispose（资源释放）时等待完全停稳的清理。它本身不定义任何终端机制：`dsh-terminal-bash` 之类的后端负责启动与就绪检测，`dsh-tool-terminal` 中的面向模型工具负责呈现。会话只存在于进程本地：harness 重启后不会恢复。
 
-- 后端注册一个稳定的 `type`，并返回尚未发布的 `TerminalBackendSession`；失败或取消的设置过程必须清理部分资源。若清理失败，则以 `TerminalBackendCleanupError` 拒绝，使注册表能在取消后继续保留该清理失败。
-- spawn 取消会保留调用方提供的确切中止原因。后端设置完成后，服务 dispose 与所有者消失仍分别对应可供机器路由的不同失败。
-- 所有者与服务的 dispose 会通过服务持有的信号中止尚未发布的设置，并等待后端结算和回滚后才返回。
-- 如果回滚关闭失败，或后端报告启动清理失败，dispose 生命周期会以拒绝结束，不会声称已经完全停稳。调用方触发的取消仍收到其确切原因；生命周期触发的回滚失败也会拒绝待完成的 spawn。
-- 调用方取消后发生的后端清理失败仍算作所有者活动，直到所有者或服务 dispose 并消费、报告该失败，避免生命周期策略把失败的清理误判为完全停稳。
-- `hasOwnerActivity(owner)` 覆盖从尚未发布的设置到最终关闭的全过程，使生命周期策略能精确限制对应所有者，不受发布竞态影响。
-- 成功的 spawn 会发布一个 `TerminalSessionId`。可选的 `name` 只是所有者本地的显示元数据，绝不代表权限。
-- 一个会话最多接受一个活跃的发送操作。读取和信号操作可以观察该发送；在当前操作结算前，另一项发送会失败。
-- `TerminalSendResult.waitReason` 与 `sessionStatus` 相互独立。`session_exit` 描述顶层 PTY 进程，而不是任意前台命令。
-- `kill()` 与 dispose 只会在后端捕获的进程树完全停稳后完成。清理失败会以拒绝结束，而非声称成功；同时它会清除匹配的后端和注册表限制，使后续关闭能够重试，且不会干扰较新的尝试。

+## 使用本包
+
+当组合需要状态跨工具调用存活的终端会话时，挂载 `@deepseek-ai/dsh-terminal`。单独的服务本身没有用处：请与 `@deepseek-ai/dsh-terminal-bash` 之类的后端、`@deepseek-ai/dsh-tool-terminal` 之类的工具包配对，并在同一个组合中一起加载。
+
+### 何时选择
+
+当工作状态存在于终端而非文件时，选择持久终端：逐步调试 gdb、在 Python 或 Node REPL 中探索，或中断前台命令后回到 shell。对于有界操作，请选择单次 bash、read、write 与 edit 工具——它们保留更强的校验、审批、输出上限与回放约定。会话只存在于进程本地：harness 进程退出时它们会消失，因此需要持久的工作应写入文件或其他持久系统。
+
+### 组合方式
+
+将会话服务与后端、工具包一起加载：
+
+```yaml
+- name: '@deepseek-ai/dsh-terminal'
+- name: '@deepseek-ai/dsh-terminal-bash'
+- name: '@deepseek-ai/dsh-tool-terminal'
+```
+
+后端提供一个稳定类型——随附的 shell 后端提供 `shell`——工具按该类型打开会话。shell 后端还额外要求沙箱、沙箱策略与子进程提供方；完整组合见其 [README](../terminal-bash/README.zh.md)。
+
+### 会话能做什么
+
+会话存在后，消费方可以：打开会话并获得其 id 与有界启动输出；发送文本（可选地提交 Enter）并等待 shell 再次就绪或发送超时；读取有界保留输出；向前台进程组投递一个允许的信号；关闭会话并等待其进程树结束；以及列出调用方拥有的会话。每个会话同一时间最多有一个活跃发送；第二次发送会失败，直到第一次结算。
+
+### 所有权与隔离
+
+每个会话都由打开它的确切 agent 拥有。凡是指名会话的操作，只要调用方不是该 agent 就会被拒绝，因此即使模型获知另一个 agent 的 id，也无法操作其终端。可选的会话 `name` 是所有者本地的显示元数据——例如 `main` 或 `gdb` 这样的标签——并且只在所有者范围内唯一。
+
+### 可观察结果与失败
+
+成功打开会返回会话 id、类型、后端存在时的 pid、状态与有界启动消息。发送以等待原因结算：`stdin_read`（shell 正在等待输入）、`inferred_idle`（输出静默）、`timeout` 或 `session_exit`（顶层 shell 已退出）。失败携带稳定的机器可路由错误码：后端类型缺失（`NO_BACKEND`）、会话未知（`NO_SESSION`）、属于其他 agent 的会话（`FOREIGN_SESSION`）、并发第二次发送（`SEND_ACTIVE`），或所有者不再存活（`OWNER_NOT_LIVE`）。后端设置失败会在发布任何内容之前拒绝打开；清理失败会拒绝关闭，而不是声称成功。

+
+本节解释服务背后的设计并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中说明。
+
+### 设计理念
+
+服务拥有终端机制以外的一切：会话身份、发布、授权与清理。后端负责会话如何启动、检测就绪、保留输出与关闭；服务只在后端设置成功后发布会话。这个拆分让同一个注册表可用于不同的终端基底。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | `TerminalSessionService`：后端注册表、spawn/send/read/signal/kill/list、所有者清理与 dispose |

+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；注册表是私有可变状态） |
+
+### 数据模型与生命周期
+
+每个已发布会话是一条记录，包含其 id、所有者、可选名称、后端类型、后端会话，以及当前唯一的活跃发送。未发布的 spawn 按所有者以预留形式跟踪，并持有服务拥有的中止信号。dispose 会中止待完成的 spawn、等待其结算与回滚，然后关闭每个拥有的会话并等待完全停稳，最后运行所有者分离器；清理失败会拒绝生命周期，而不是声称成功。
+
+### 所有权与清理规则
+
+- 限制基于确切的 `Agent` 对象：`hasOwnerActivity(owner)` 覆盖从尚未发布的设置到最终关闭的全过程，没有发布竞态，因此生命周期策略可以精确限制所有者。
+- 无法清理部分启动资源的后端会以 `TerminalBackendCleanupError` 拒绝；服务会将该失败保留为受跟踪的所有者活动，直到所有者或服务 dispose 消费并报告它。
+- 调用方取消保留其确切的 `AbortSignal.reason`；`kill()` 与 dispose 只在后端捕获的进程树完全停稳后完成。
+
+### 发送预留
+
+服务在返回操作之前同步为一个活跃发送预留会话，包括在后台 job id 可见之前；第二次发送会以 `SEND_ACTIVE` 失败，因此输出与取消永远不会跨操作所有权。

 # @deepseek-ai/dsh-tool-terminal
 
 English | [中文](README.zh.md)
 
-Six model-facing tools over `ctx.terminals`: `terminal_open`, `terminal_send`, `terminal_read`, `terminal_signal`, `terminal_close`, and `terminal_list`. Every operation requires the exact initiating `Agent`, so a model cannot address another agent's terminal even if it learns the id.
+## Summary
 
-`terminal_send(run_in_background: true)` reuses `ctx.jobs`; job preflight and the PTY service's exclusive per-session send reservation occur before the job id is returned, completion is collected with `job_output`, and `job_kill` delivers `SIGINT` to the foreground process group. Foreground sends use terminal call/result cards. Background sends use a generic execute card; open, read, signal, close, and list use generic `execute`, `read`, `execute`, `delete`, and `read` cards respectively. None declares source locations.
+`dsh-tool-terminal` gives the model six tools over persistent terminal sessions: `terminal_open`, `terminal_send`, `terminal_read`, `terminal_signal`, `terminal_close`, and `terminal_list`. Every call is fenced to the exact agent that opened the session, so a model cannot operate another agent's terminal even if it learns the id. Sends run in the foreground (returning bounded output with a wait reason) or in the background through the jobs service (returning a job id collected with `job_output` and stopped with `job_kill`). Results are capped by `maxResultBytes` and stay in session history until compaction. A short guidance section tells the model to prefer one-shot tools unless a terminal's persistent state or interactive stdin is genuinely needed.

-Both values are validated at load. The minimum result cap keeps every registry-issued session or job id visible in its creation acknowledgement. When a result exceeds `maxResultBytes`, rendering reserves space for control metadata and a truncation marker when they fit; cuts preserve UTF-8 boundaries. Each terminal definition's final-content callback applies the same cap after normalized pre-, around-, and post-execute policy failures, denials, short-circuits, replacements, or blocks; a structured multi-block policy result retains its shape.

+<a id="use-this-package"></a>
+## Use this package
+
+Enable these tools when the composition mounts a terminal backend and the model should be able to use terminal state across calls — stepping a debugger, exploring in a REPL, or returning to a shell after interrupting a foreground command. The guidance section steers the model toward the one-shot bash, read, write, and edit tools for bounded operations.
+
+### The six tools
+
+| Tool | What it does | Result |
+|---|---|---|
+| `terminal_open` | Creates an owner-scoped session from a backend type | Session id, name, type, pid, status, and bounded startup output |
+| `terminal_send` | Writes text, optionally submitting Enter, and waits for readiness — or starts a background job | Bounded output plus wait and session status, or a job id |
+| `terminal_read` | Reads a bounded page of retained output without sending input | Text with line pagination metadata |
+| `terminal_signal` | Delivers one allowed signal to the foreground process group | `delivered` plus the target process group id |
+| `terminal_close` | Closes a session and waits for its process tree to end | Closed or already-closing outcome |
+| `terminal_list` | Lists the caller's live sessions | Owner-scoped session summaries |
+
+### Composition
+
+```yaml
+- name: '@deepseek-ai/dsh-terminal'
+- name: '@deepseek-ai/dsh-terminal-bash'
+- name: '@deepseek-ai/dsh-tool-terminal'
+```
+
+The tools need `ctx.terminals` — a backend must be mounted — and the system-prompt service for the guidance section. Background sends additionally require the jobs service and its model-facing controller (`@deepseek-ai/dsh-tool-jobs`).
+
+### Configuration
+
+| Field | Default | Meaning |
+|---|---|---|
+| `enableRunInBackground` | `true` | Expose and accept `run_in_background`; `false` removes the schema field and rejects the argument |
+| `maxResultBytes` | `262144` | UTF-8 cap (minimum `64`) for each complete terminal result after wait, session, pagination, truncation, and job-status metadata |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-tool-terminal) and [tool catalog](../../../docs/tool-catalog.md#deepseek-aidsh-tool-terminal) are the exhaustive sources for config fields and schemas.
+
+### Background sends
+
+`terminal_send(run_in_background: true)` returns a job id immediately instead of waiting. The job is collected with `job_output`, which waits and reads incremental output, and stopped with `job_kill`, which delivers a real `SIGINT` to the foreground process group. Background mode fails before writing input when the jobs surface is absent.
+
+### Observable outcomes and failures
+
+A foreground send returns the terminal's new output plus `wait: <reason>` and the session status; `session_exit` means the top-level shell exited, while `inferred_idle` or `timeout` never proves the foreground command exited. Opening a session with an unregistered backend type fails. Results larger than `maxResultBytes` are truncated at a UTF-8 boundary with a marker.

+
+This section explains the design behind the tools and points at the code that realizes it; the observable behavior is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The package is a thin adapter: the six tools forward to `ctx.terminals` with the executing agent as the owner, and the presentation layer renders bounded results. Background sends register the in-flight operation on `ctx.jobs` so the generic job surface owns waiting, incremental reads, and `SIGINT` delivery.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Six tool definitions, schemas, guidance section, background-job integration |
+| [`src/render.ts`](src/render.ts) | Result rendering and the complete-result UTF-8 cap |
+
+### Result bounding
+
+Every terminal-owned single-text result is capped by `maxResultBytes` after normalized tool or pipeline errors, policy denials and short-circuits, replacements and blocks, and generic job-status text; cuts preserve UTF-8 boundaries and reserve room for a truncation marker. Structured multi-block policy results retain their shape. The minimum cap of 64 bytes keeps every registry-issued session or job id visible in its creation acknowledgement.
+
+### UI render intents
+
+Foreground sends use terminal call and result cards; background sends and the other five tools use generic `execute`, `read`, or `delete` cards. None of the tools emits source locations.

-基于 `ctx.terminals` 提供 6 个面向模型的工具：`terminal_open`、`terminal_send`、`terminal_read`、`terminal_signal`、`terminal_close` 和 `terminal_list`。每项操作都要求提供完全相同的发起 `Agent`，因此即使模型获知另一个 agent（智能体）的 id，也无法操作其终端。
+## 概述
 
-`terminal_send(run_in_background: true)` 会复用 `ctx.jobs`；任务预检和 PTY 服务对每个会话的独占发送预留都发生在返回 job id 之前。系统通过 `job_output` 收集完成结果，`job_kill` 则向前台进程组发送 `SIGINT`。前台发送使用终端调用／结果卡片。后台发送使用通用执行卡片；打开、读取、发送信号、关闭和列出操作则分别使用通用 `execute`、`read`、`execute`、`delete` 和 `read` 卡片。所有操作都不声明源位置。
+`dsh-tool-terminal` 基于持久终端会话为模型提供 6 个工具：`terminal_open`、`terminal_send`、`terminal_read`、`terminal_signal`、`terminal_close` 与 `terminal_list`。每次调用都被限制在打开该会话的那个确切 agent（智能体）内，因此即使模型获知另一个 agent 的 id，也无法操作其终端。发送可以前台运行（返回带等待原因的有界输出），也可以通过任务服务后台运行（返回 job id，用 `job_output` 收集、用 `job_kill` 停止）。结果受 `maxResultBytes` 限制，并保留在会话历史中直到压缩（compaction）。一段简短指引会告诉模型：除非确实需要终端的持久状态或交互式 stdin，否则优先使用单次工具。

+## 使用本包
+
+当组合挂载了终端后端、且模型应当能跨调用使用终端状态时启用这些工具——逐步调试 gdb、在 REPL 中探索，或中断前台命令后回到 shell。指引章节会引导模型对确有界操作使用单次 bash、read、write 与 edit 工具。
+
+### 六个工具
+
+| 工具 | 作用 | 结果 |
+|---|---|---|
+| `terminal_open` | 按后端类型创建限定所有者范围的会话 | 会话 id、名称、类型、pid、状态与有界启动输出 |
+| `terminal_send` | 写入文本，可选地提交 Enter，并等待就绪——或启动后台任务 | 有界输出加等待与会话状态，或一个 job id |
+| `terminal_read` | 不发送输入，读取一页有界保留输出 | 带行分页元数据的文本 |
+| `terminal_signal` | 向前台进程组投递一个允许的信号 | `delivered` 加目标进程组 id |
+| `terminal_close` | 关闭会话并等待其进程树结束 | 已关闭或正在关闭的结果 |
+| `terminal_list` | 列出调用方的活跃会话 | 限定所有者范围的会话摘要 |
+
+### 组合方式
+
+```yaml
+- name: '@deepseek-ai/dsh-terminal'
+- name: '@deepseek-ai/dsh-terminal-bash'
+- name: '@deepseek-ai/dsh-tool-terminal'
+```
+
+工具需要 `ctx.terminals`——必须挂载一个后端——以及用于指引章节的系统提示词服务。后台发送还额外要求任务服务及其面向模型的控制器（`@deepseek-ai/dsh-tool-jobs`）。

+
+### 设计理念
+
+本包是薄适配层：6 个工具以执行 agent 作为所有者转发到 `ctx.terminals`，呈现层渲染有界结果。后台发送把在途操作注册到 `ctx.jobs`，由通用任务接口面负责等待、增量读取与 `SIGINT` 投递。

+### 结果上限
+
+每个终端自身的单文本结果都会在规范化后的工具或流水线错误、策略拒绝与短路、替换与阻止、以及通用任务状态文本之后，受 `maxResultBytes` 限制；截断保留 UTF-8 边界并为截断标记预留空间。结构化的多块策略结果保留其结构。64 字节的最小上限保证注册表签发的每个会话或 job id 都出现在创建确认中。
+
+### UI 呈现意图

+`dsh-agent-loop-testkit` mounts the standard prerequisite services a test needs before loading the concrete `AgentLoop` — the LLM runtime, session store, system-prompt registry, tool registry, and agent registry — in dependency order, with one call. The loop itself, adapters, optional plugins, agents, and teardown stay in the test's hands, so each scenario keeps its own load order and topology. Use it when a test's subject is loop behavior rather than service wiring; tests that probe injection failures or partial topologies mount their dependencies directly. It registers no model-facing behavior of its own.

-Tests of injection failures, partial topology, service load order, or service teardown mount their dependencies directly instead of using this helper.
+The helper activates the LLM, session, system-prompt, tool, and agent services in dependency order and returns before the loop is mounted. System-prompt and tool-registry configuration can be forwarded through `options`; the helper provides no test defaults beyond those the services own.
 
+### When to use it
+
+Use the helper for tests whose subject is the loop: load order, retries, tool execution, or session behavior on a real prerequisite stack. Mount dependencies directly when a test probes service load order, injection failures, partial topologies, or teardown — the helper hides exactly the wiring such tests must control.
+
+### What can go wrong
+
+A plugin-load failure rejects the helper call; services activated earlier in the sequence remain owned by your context and unwind with it. The context owns every mounted service, so dispose it after the test.

+
+This section explains the design of the helper; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design
+
+The helper is one function, `mountAgentLoopTestDependencies`, that mounts five service plugins in a fixed dependency order — LLM, session, system-prompt, tool registry, then agent registry — and deliberately stops before `AgentLoop` itself, so the caller controls loop load order and the topology under test. Ownership stays with the caller's context: every mounted service is context-owned, a plugin-load failure rejects the promise, and earlier services unwind with the context. The implementation lives in [`src/index.ts`](src/index.ts); the [`src/invariant.ts`](src/invariant.ts) companion declares no runtime invariant because the package owns no production event stream or mutable data — consuming test suites exercise its behavior.

-jsdom slot test runtime for client feature specs: a real Cordis `Context`, the renderer-owned `SlotRegistry`, and the production `UiSession` adapter assembled around typed Session and Workspace Controller doubles. Feature suites exercise declaration, registration, scope, store, injection, rendering, updates, and disposal without copying production renderer or adapter logic.
+## Summary
 
-The doubles implement the owner interfaces consumed through Cordis: `TestSessions implements ISessions`, `TestWorkspaces implements IWorkspaces`, each fixture Session is a `FixtureSession implements SessionFace`, and `stubSettingsScope` implements `SettingsScope`. The runtime mounts `UiSession`, which derives renderer standard sources from Controller bindings. Fixtures publish Session lifecycle state through `updateSessionSnapshot`, Workspace state through `TestWorkspaces.update`, projection values through the Session face, and Conversation input through the Session event feed. Unstubbed `ISession` behavior fails with the missing method name.
+`dsh-client-test-runtime` gives a browser feature spec a real jsdom test bench: it assembles a Cordis context, the renderer-owned slot registry, and the production `UiSession` adapter around typed Session and Workspace Controller doubles. Feature suites exercise declaration, registration, scoping, stores, injection, rendering, updates, and disposal without copying production renderer or adapter logic. Suites publish Session lifecycle state, Workspace state, projection values, and Conversation events through typed fixtures, then use local DOM snapshot roots, scoped Testing Library queries, and fail-loud service checks. It is not part of the product plugin graph (no `dsh.client`); feature packages depend on it in `devDependencies` only.
 
-Local DOM snapshots: `declare(children)` registers an auto frame whose per-key `<div data-slot>` wrappers are snapshot roots; `renderSlot(key, owner)` returns the slot-local view (container, scoped Testing Library queries, in-place `update(owner)`); a registered snapshot serializer folds CSS-module class hashes (`_frame_a1b2c3` → `frame`) to keep `.snap` files structural and collapses `<svg>` internals to a `data-content` fingerprint. Suites needing a custom page frame use `root.declare(children, Frame)` instead; `mount(plugin)` runs a real fiber with fail-loud service prechecks, and `dispose()` tears down views, feature fibers, minted scopes, and persisted store state on one axis.

+## Use this package
+
+This package gives a browser feature spec a real runtime to mount against: create the bench, declare the slots your feature occupies, mount the feature plugin, render a slot, assert on the local view, and dispose — with no second implementation of production logic.
+
+### Setting up a feature spec
+
+`SlotTestRuntime.create()` assembles the runtime, `declare(children)` registers an auto frame whose per-key `<div data-slot>` wrappers become snapshot roots, `mount(plugin)` runs the feature on a real fiber, and `renderSlot(key, owner)` returns the slot-local view with scoped queries and in-place updates:
+
+```text
+const runtime = await SlotTestRuntime.create()
+await runtime.declare({ 'feature-slot': {} })
+const handle = await runtime.mount(FeaturePlugin)
+const view = runtime.renderSlot('feature-slot', { owner: props })
+expect(view.container).toMatchSnapshot()
+await runtime.dispose()
+```
+
+`mount` prechecks required services and fails loud when one is missing — `provide(name, value)` supplies an extra service first. `storeOf(key, scopeKey)` returns the live store instance the renderer hands a slot's component for identity and action-driven-write assertions.
+
+### Local DOM snapshots
+
+A registered snapshot serializer folds CSS-module class hashes (`_frame_a1b2c3` → `frame`) so `.snap` files stay structural, and collapses `<svg>` internals to a `data-content` fingerprint. Suites needing a custom page frame use `root.declare(children, Frame)` instead of the auto frame; `dispose()` tears down views, feature fibers, minted scopes, and persisted store state on one axis and is idempotent.
+
+### When to use it
+
+Use the bench for feature suites that exercise slots, stores, rendering, and disposal under a real runtime — the production `SlotRegistry`, renderer, and provide-bundle materialization are mounted, never reimplemented. It is browser-side test infrastructure: it never reaches a model request, and feature packages depend on it in `devDependencies` only.
+
+### What can go wrong
+
+- **A declared service is not provided** — `mount` fails loud with the missing names; `provide()` them first.
+- **A render is attempted before `declare`** — `renderSlot` fails loud; declare the key first.
+- **A spec calls an unstubbed verb on a session behavior stub** — fixture stubs fail loud by design, so a missing stub surfaces at the call site rather than silently passing.

+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design of the bench; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design
+
+The bench copies no production logic: it mounts the production `SlotRegistry`, production renderer, and `UiSession` adapter. `TestSessions` and `TestWorkspaces` implement the owner interfaces that features consume through Cordis, each fixture Session implements `SessionFace`, and `stubSettingsScope` implements `SettingsScope`. `UiSession` derives standard renderer sources from those Controller bindings. Unstubbed `ISession` behavior fails with the missing method name.

+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; the mounted production packages own theirs) |
+
+### Lifecycle
+
+`create()` builds a fresh context, mounts the slot and conversation registries, installs the renderer, and provides the session/workspace doubles. `mount` checks every declared injection against the context before starting the fiber, so a missing provider fails loud instead of suspending forever. `dispose()` unmounts React trees first, then disposes feature fibers, releases the root registration, disposes minted session scopes, and clears persisted store state; every public mutator is act-wrapped, so tests never handle SlotCore microtask batching or React `act` themselves.

-面向客户端功能测试的 jsdom slot 测试运行时：真实 Cordis `Context`、renderer 所有的 `SlotRegistry` 与生产 `UiSession` adapter，围绕带类型的 Session 和 Workspace Controller 测试替身组装。功能套件无需复制生产 renderer 或 adapter 逻辑，即可测试声明、注册、scope、store、注入、渲染、更新与销毁。
+## 概述
 
-替身实现通过 Cordis 消费的 owner 接口：`TestSessions implements ISessions`、`TestWorkspaces implements IWorkspaces`，每个 fixture Session 是 `FixtureSession implements SessionFace`，`stubSettingsScope` 实现 `SettingsScope`。运行时挂载 `UiSession`，由它从 Controller binding 派生 renderer 标准 source。fixture 通过 `updateSessionSnapshot` 发布 Session 生命周期状态，通过 `TestWorkspaces.update` 发布 Workspace 状态，通过 Session face 发布 projection 值，并通过 Session event feed 提供 Conversation 输入。未打桩的 `ISession` 行为会在错误中指出缺失方法。
+`dsh-client-test-runtime` 让浏览器功能测试拥有真实的 jsdom 测试台：它把 Cordis 上下文、渲染器拥有的 slot 注册表与生产 `UiSession` 适配器组装在带类型的 Session 和 Workspace Controller 替身周围。功能套件无需复制生产渲染器或适配器逻辑，即可检验声明、注册、作用域、store、注入、渲染、更新与销毁。套件通过带类型 fixture 发布 Session 生命周期状态、Workspace 状态、projection 值与 Conversation 事件，再使用局部 DOM 快照根、限定范围的 Testing Library 查询与自明的服务缺失检查。它不属于产品插件图（无 `dsh.client`）；feature 包仅以 `devDependencies` 依赖之。
 
-局部 DOM 快照：`declare(children)` 注册自动 frame，逐 key 的 `<div data-slot>` 包裹层即快照根；`renderSlot(key, owner)` 返回该 slot 的局部视图（container、限定范围的 Testing Library 查询、原位 `update(owner)`）；注册的快照序列化器把 CSS-module 哈希类名折回语义名（`_frame_a1b2c3` → `frame`）保持 `.snap` 只含结构，并把 `<svg>` 内部折叠为 `data-content` 指纹。需要自定义页面 frame 的套件改用 `root.declare(children, Frame)`；`mount(plugin)` 在真实 fiber 上运行并对缺失服务先行报错；`dispose()` 沿单一轴拆除视图、feature fiber、已铸 scope 与持久化 store 状态。

+## 使用本包
+
+本包让浏览器功能测试拥有可挂载的真实运行时：创建测试台，声明你的功能所占用的 slot，挂载功能插件，渲染一个 slot，在局部视图上断言，然后 dispose（资源释放）——全程不存在生产逻辑的第二份实现。
+
+### 搭建功能测试
+
+`SlotTestRuntime.create()` 组装运行时，`declare(children)` 注册一个自动 frame，其逐 key 的 `<div data-slot>` 包裹层成为快照根，`mount(plugin)` 在真实 fiber 上运行功能，`renderSlot(key, owner)` 返回带限定查询与原位更新的 slot 局部视图：
+
+```text
+const runtime = await SlotTestRuntime.create()
+await runtime.declare({ 'feature-slot': {} })
+const handle = await runtime.mount(FeaturePlugin)
+const view = runtime.renderSlot('feature-slot', { owner: props })
+expect(view.container).toMatchSnapshot()
+await runtime.dispose()
+```
+
+`mount` 会预检必需服务，缺失时自明报错——先用 `provide(name, value)` 提供额外服务。`storeOf(key, scopeKey)` 返回渲染器交给 slot 组件的实时 store 实例，用于身份与动作驱动写入断言。
+
+### 局部 DOM 快照
+
+注册的快照序列化器把 CSS-module 哈希类名折回语义名（`_frame_a1b2c3` → `frame`），使 `.snap` 文件只含结构，并把 `<svg>` 内部折叠为 `data-content` 指纹。需要自定义页面 frame 的套件改用 `root.declare(children, Frame)` 而非自动 frame；`dispose()` 沿单一轴拆除视图、feature fiber、已铸 scope 与持久化 store 状态，且幂等。
+
+### 何时使用
+
+当功能套件要在真实运行时下检验 slot、store、渲染与销毁时使用本测试台——生产 `SlotRegistry`、渲染器与 provide bundle 物化都会被挂载，绝不重实现。它是浏览器侧测试基础设施：永远不触及模型请求，feature 包仅以 `devDependencies` 依赖之。
+
+### 可能出什么问题
+
+- **已声明服务未提供**——`mount` 自明报错并列出缺失名称；请先用 `provide()` 提供。
+- **在 `declare` 之前尝试渲染**——`renderSlot` 自明报错；请先声明该 key。
+- **测试调用会话行为桩上未打桩的动词**——fixture 桩按设计自明报错，缺失的桩会在调用点浮现，而非静默通过。

+
+### 设计
+
+测试台不复制生产逻辑：它挂载生产 `SlotRegistry`、生产渲染器与 `UiSession` 适配器。`TestSessions` 与 `TestWorkspaces` 实现功能通过 Cordis 消费的 owner 接口，每个 fixture Session 实现 `SessionFace`，`stubSettingsScope` 实现 `SettingsScope`。`UiSession` 从这些 Controller binding 派生标准渲染器 source。未 stub 的 `ISession` 行为会携缺失方法名失败。

-A scriptable OpenAI-compatible HTTP/SSE server for exercising real LLM adapters, the agent loop, and recovery policy without a provider key. It accepts `POST /chat/completions` and `POST /v1/chat/completions`; each accepted request consumes one configured behavior in arrival order. Invalid methods, paths, bearer tokens, and JSON do not consume the script.
+## Summary
 
-The library entry exports `startMockLlmServer(options)`, behavior and telemetry types, the default random stress weights, the accepted Node timer bound, and a running handle with the bound `baseURL`, generated or configured `randomSeed`, captured requests, and idempotent `close()`. Closing force-terminates stalled connections.
+`dsh-llm-mock-server` stands in for a real model provider during tests as a scriptable OpenAI-compatible HTTP/SSE server: you script a sequence of wire behaviors — stream resets, stalls, malformed chunks, rate limits, server errors, successful completions, tool calls — and each accepted `/chat/completions` request consumes the next one. It serves the shipping DeepSeek adapter and the agent loop over real HTTP, so recovery policy such as retries, backoff, and timeouts is exercised against a genuine wire boundary without a provider key. A CLI (`pnpm run mock:llm`) runs the server standalone; the library entry `startMockLlmServer` embeds it in tests and returns captured requests. A `random` behavior with seeded weights mixes failures for open-ended stress runs.

-## Timing and content controls
+### Timing and content controls
 
 The CLI exposes `--success-text`, `--partial-text`, `--reasoning-text`, `--chunk-size`, `--chunk-delay-ms`, `--disconnect-delay-ms`, `--retry-after-ms`, `--request-id`, `--tool-name`, and `--tool-arguments`. Millisecond delays are bounded integers within Node's timer range; `retryAfterMs` must also be positive. The library accepts the same camel-case options. An optional exact `apiKey` validates `Authorization: Bearer <token>`; omission accepts any token.
 
+### What can go wrong
+
+- **The script runs out** — exhaustion returns a structured HTTP 500; set `--repeat-last` or lengthen the sequence when a run needs more requests.
+- **Random weights without a positive concrete behavior are rejected** — every entry must name an existing behavior and at least one must carry positive weight.
+- **Invalid requests do not consume the script** — wrong methods, paths, bearer tokens, and malformed JSON get ordinary 4xx responses, so a misconfigured client can burn retries without advancing the sequence.

+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design of the server; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design
+
+The server is built on one rule: each accepted chat-completions request consumes exactly one behavior from an arrival-ordered FIFO cursor, and the server never retries or interprets harness policy. Validation happens before the cursor advances — only a `POST` whose path ends in `/chat/completions`, with a valid bearer token when one is configured and a parseable JSON body, consumes the script; everything else receives an ordinary 4xx. `random` entries resolve at request time through a seeded PRNG over the configured weights, so a run is reproducible from its printed seed.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | `startMockLlmServer`: listener, behavior table, seeded randomness, telemetry, captured request records |
+| [`src/cli.ts`](src/cli.ts) | `--sequence` and timing/content option parsing, JSONL stdout telemetry |
+| [`src/bin.ts`](src/bin.ts) | The `pnpm run mock:llm` source entry |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; wire behavior is exercised through HTTP tests) |
+
+### Wire flow
+
+A request enters the handler, is validated, and selects a behavior: a concrete script entry runs directly, `random` draws one, and an exhausted script reports `script_exhausted` as a structured 500. `runBehavior` then executes the wire result — socket destroy, SSE stream, JSON error, or completion — while every request and outcome is recorded in arrival order on the returned handle for test assertions. `close()` stops accepting requests and force-terminates stalled connections.

+These limits define when the server needs special care. They are current package constraints, not a task backlog.
+
 - **Random weights model test pressure, not production incidence** — callers that want an environment-specific distribution must provide measured weights and record the emitted seed.
 - **Request scripts are arrival-ordered** — concurrent callers share one cursor, so deterministic per-session fault assignment requires separate server instances.
 - **True connection refusal is a listener lifecycle phase** — the CLI delay must overlap the client attempt; request-level random selection can only reset an accepted connection.

 # @deepseek-ai/dsh-llm-replay
 
 English | [中文](README.zh.md)
 
-A replay LLM plugin for keyless snapshot tests. It yields model streams reconstructed from a recorded **session JSONL** fixture, so a test can boot the real agent against a fixed model transcript with no API key. With `providers` configured it registers a replay-only adapter whose catalog is available to scenarios that exercise model discovery; without `providers` it installs the catch-all `llm/stream` waterfall used by tests that do not need discovery.
+## Summary
 
-Its consumers are the ACP and headless `stream-json` snapshot suites plus the Web browser e2e lane. Loader-driven suites mount this plugin in place of a real LLM adapter; the Web lane installs it directly to retain the teardown consumption handle.
+`dsh-llm-replay` makes snapshot tests run without an API key: it installs a replay LLM adapter that serves model streams reconstructed from a recorded session JSONL fixture, so a test boots the real agent against a fixed transcript. The fixture is a projection of the persisted session log — `assistant/chunk` events group into per-call chunk sequences, and an explicitly marked local compaction call replays as one canonical stream. A `replay.override.json` sidecar covers what a log cannot reconstruct: a throw before any chunk, a cancel/hang, or an injected retry. Live sessions bind to recorded scripts by first-call order, so parent-and-subagent scenarios each get their own script. It is the model source behind the ACP and headless snapshot suites and the Web browser e2e lane.
 
-## How the fixture works
+## Table of Contents
 
-The fixture is a projection of a persisted session log (`<scenario>/session.jsonl`): it keeps the header and every event payload, but omits body `seq`/`time` envelopes (`seq0`/`time0` for packed rows). Replay restores contiguous synthetic envelopes while parsing; one file must contain either projected body rows or complete persisted body rows, never both. Runtime persistence still writes the complete log. The fixture's `assistant/chunk` events carry every `StreamChunk`, so grouping them by `(turn, step)` reconstructs each agent-loop `stream()` call's chunk sequence. A successful compaction summarizer is logged differently: when `compaction/summary` carries `llmStreamCall: true` and its complete `rawOutput`, replay reconstructs a canonical successful stream at that event's position using one `block-start`/`block-end` pair per block, the recorded usage when present, and a terminal `stop`. Exact provider delta partitioning is not part of the durable compaction result. `rawOutput` without the marker does not imply a local LLM call because template and remote summarizers may retain complete output without using this context's adapter.

+- [Further Exploration](#further-exploration)
+- [Model Experience](#model-experience)
+- [Known Limitations and Deferred Work](#known-limitations-and-deferred-work)
+- [Dev Note](#dev-note)
 
-Recording is therefore "run the real agent once and harvest the `.jsonl`", done by the snapshot harness — this plugin does not record. A fixture may carry its `request/header` content tokenized to `{{system}}`/`{{tools}}` (the harness pins that content in one scenario and scrubs the rest); replay is indifferent — derivation reads only `assistant/chunk` and `compaction/summary` events plus the line-0 session header.
+-----
 
-When replay serves `deepseek-official` in a composition carrying `ctx.deepseekLlmApiExtensions`, it prepares and accepts those fields after selecting a valid script entry and before yielding its first chunk. This mirrors the live adapter's post-2xx commit point, so durable acceptance watermarks and SDK event notifications remain identical between recording and replay. Replay supplies a synthetic `{ messages: [] }` base body: it proves acceptance side effects, not prepared field bytes. An extension whose acceptance action depends on the serialized provider body needs dedicated fixture support before this replay path can represent it. Other provider routes and compositions without the optional registry are unchanged.
+<a id="use-this-package"></a>
+## Use this package
 
-Two failure modes are not reconstructable from `assistant/chunk` alone — a pure throw before any chunk (e.g. an HTTP 401, where the log holds only a `turn/end {error}` and no chunks) and a cancel/hang (timing, not chunk content). A scenario that needs those supplies an optional sidecar (`<scenario>/replay.override.json`) that either replaces the derived script (a bare `ReplayEntry[]`) or augments it (`{ patches: [{ at, entry }] }`: keep every JSONL-derived call and swap the named 0-based call indexes; `at` equal to the derived length appends the retry attempt after an injected transient throw). Patch indexes must be unique. A `throw` entry accepts DeepSeek request extensions when it has prefix chunks; a zero-chunk throw defaults to pre-2xx non-acceptance and can set `accepted: true` for a post-2xx failure without chunks. The override document, each patch and entry, and every chunk discriminant are validated when the file loads. A `hang` entry may name `readyFile`; replay writes that empty marker after its prefix chunks reach the loop and before it waits for cancellation, so an external driver can cancel deterministically without observing a presentation update.
+This package gives a keyless test a real agent with a fixed model transcript: mount it in place of a real LLM adapter, point it at a recorded fixture, and run the scenario exactly as if the model had produced the recorded output.
 
-A scripted string may embed `{{fromRequest:<regex>}}` to fill a value no static sidecar can know — for example a randomly minted goal id the model must echo back into `update_goal`. At stream time every placeholder resolves against the live request: the corpus is every string leaf of the request messages joined by newlines, the pattern's LAST corpus match wins, and its first capture group (or the whole match without one) substitutes in place. A pattern that matches nothing, an invalid pattern, and an unterminated placeholder each fail loud. The last two braces of a consecutive `}` run terminate the placeholder, so a pattern may end with a brace quantifier (`[0-9a-f]{4}`) but cannot contain `}}` followed by further pattern content. Resolution applies to every scripted entry, including ones derived from the recorded JSONL — a recorded fixture whose text legitimately contains the literal marker must be expressed through a sidecar without it.
+### Mounting it
 
-## Nested agents: per-session keying
-
-A scenario where a parent agent delegates to in-process subagents records more than one log: the parent (`session.jsonl`) plus one per child (`session.1.jsonl`, …). Each agent runs as its own `Session` on the same context, so replay must serve each one its own script.
-
-Replay keys every call by its calling session id (`GenerateOptions.sessionId`, stamped by the agent loop). Live session ids are freshly random each run and never equal the recorded ones, so a live session binds to a recorded script by **first-call order**: scripts are ordered by header `createdAt` (parent first — it streams before it can delegate), and the first live session to make any call claims the first script, the next new session the next, and so on. Each session then advances its own cursor. A call with no `sessionId` is one anonymous session bound to the primary script. More distinct live sessions than recorded scripts fails loud.

-| `providers` | `ReplayProviderConfig[]` | — | Optional replay-only provider and model catalog. Each provider may set `retryPolicy`, and each model may publish `contextWindow`, an `inputModalities` array containing only `text` and `image`, and a positive-integer `imageRequestTokens` flat visual-token price the route declares for every retained request image (its model must also declare the `image` modality); invalid modalities, a non-positive price, or visual pricing on a text-only model fail during plugin loading. Configured routes dispatch through the replay adapter and never perform provider I/O. |
-| `paceMs` | number | — (burst) | Optional per-chunk delay in ms so downstream transports (e.g. the web SSE mux observed by a real browser) see genuinely incremental delivery. A realism knob only — tests must not depend on it for correctness. Non-negative integer; abort during a pace wait cancels the stream promptly. |

-- `installLlmReplay(ctx, config)` — install the configured replay adapter or catch-all `llm/stream` listener; returns a `ReplayHandle` (`dispose()` for HMR safety plus `assertConsumed()`, the teardown check that every recorded script bound to a live session and every bound cursor drained — turning a scenario that silently drove fewer model calls than recorded into a crisp diagnostic). Use this in tests to drive replay without the Loader or env vars.
-- `loadSessionScripts(config)` — resolve the ordered `SessionScript[]` (primary + children) for a scenario, ready to bind to live sessions in first-call order.
-- `loadReplayScript(config)` — resolve the `ReplayEntry[]` for the primary session only (validated sidecar replacement/patches if present, else derived from the JSONL; fail-loud if the fixture is missing).
-- `deriveReplayScript(events)` / `parseSessionLog(text)` / `parseSessionHeader(text)` / `resolveScriptedEntry(entry, messages)` — the pure helpers that turn ordinary loop chunks and explicitly marked local compaction outputs in a persisted or projected session log into a script, read its header `id`/`createdAt`, and resolve `{{fromRequest:...}}` placeholders against one live request. A derived assistant group must end in a `finish` chunk; a group without one is the fingerprint of a thrown `stream()` and must instead be expressed via an override sidecar.
-- Types `ReplayEntry` / `ReplayOverrideDoc` / `ReplayOverridePatch` / `SessionScript` / `ReplayConfig` / `ReplayProviderConfig` / `ReplayModelConfig` / `ReplayHandle` / `Config`.
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-llm-replay) is the exhaustive source for every accepted field and its JSDoc.
 
-## Plugin export shape
+### How the fixture works
 
-Named `name` / `inject` / `Config` / `apply`, with **no default export**: the cordis Loader's `unwrapExports` does `exports.default ?? exports`, so a stray default would collapse the module to the bare function and drop the `inject` namespace (see [docs/postmortem/0001](../../../docs/postmortem/0001-acp-default-export-drops-inject.md)).
+The fixture is a projection of a persisted session log (`<scenario>/session.jsonl`) produced by running the real agent once — this plugin does not record. It keeps the header and every event payload but omits body `seq`/`time` envelopes (`seq0`/`time0` for packed rows); replay restores contiguous synthetic envelopes while parsing, and one file cannot mix projected and complete body rows. Runtime persistence continues to write complete logs. Replay derives each model call's chunk sequence from `assistant/chunk` events, so a recorded fixture replays the same logical stream the live model produced. A fixture may carry its `request/header` content tokenized to `{{system}}`/`{{tools}}`; replay is indifferent because derivation reads only the chunk and summary events plus the line-0 session header.
 
+### Nested agents
+
+A scenario where a parent agent delegates to in-process subagents records one log per session: the parent (`session.jsonl`) plus one per child (`session.1.jsonl`, …). Live session ids are freshly random each run, so replay binds each live session to a recorded script by first-call order: the first live session to make a model call claims the first script, the next new session the next, and so on, with each session advancing its own cursor. More distinct live sessions than recorded scripts fails loud.
+
+### Failure modes and overrides
+
+When replay serves `deepseek-official` with `ctx.deepseekLlmApiExtensions`, it prepares and accepts those fields after selecting a valid script entry and before yielding the first chunk. This mirrors the live adapter's post-2xx commit point, so durable acceptance watermarks and SDK event notifications behave the same in recording and replay. Replay supplies a synthetic `{ messages: [] }` base body: it proves acceptance side effects, not prepared field bytes.
+
+Two failure modes are not reconstructable from `assistant/chunk` alone — a pure throw before any chunk (for example an HTTP 401, where the log holds only a `turn/end {error}`) and a cancel/hang. A scenario that needs those supplies an optional sidecar (`<scenario>/replay.override.json`) that either replaces the derived script with a bare `ReplayEntry[]` or augments it with `{ patches: [{ at, entry }] }`, which keeps every derived call and swaps the named 0-based call indexes; `at` equal to the derived length appends the retry attempt after an injected transient throw. A `throw` entry accepts DeepSeek request extensions when it has prefix chunks; a zero-chunk throw defaults to pre-2xx non-acceptance and may set `accepted: true` for a post-2xx failure. A `hang` entry may name `readyFile`, which replay writes before waiting for cancellation so an external driver can cancel deterministically.
+
+### What can go wrong
+
+- **The fixture is not fully consumed** — `assertConsumed()` at teardown turns a scenario that silently drove fewer model calls than recorded into a crisp diagnostic; call it when installing replay directly in a test.
+- **An unrecorded session makes a call** — replay fails loud and tells you to re-record the scenario.
+- **A scripted placeholder matches nothing** — `{{fromRequest:<regex>}}` resolution validates the pattern and the request corpus and fails loud on no match, an invalid pattern, or an unterminated placeholder.

+## Understand the implementation

+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design of the replay plugin; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design
+
+Replay is built on one idea: the projected session log is the fixture. `deriveReplayScript` parses the JSONL header (for `id`/`createdAt` ordering facts) and splits `assistant/chunk` events at every `finish` chunk, keyed by `(turn, step)`, so each recorded `stream()` call becomes one `chunks` entry; an assistant group without a `finish` chunk is the fingerprint of a thrown `stream()` and must be expressed through an override sidecar. A `compaction/summary` carrying `llmStreamCall: true` and a complete `rawOutput` replays as one canonical successful stream at that event's position. Scripted strings may embed `{{fromRequest:<regex>}}`; at stream time each placeholder resolves against the live request's string leaves, taking the pattern's last match and its first capture group (or the whole match) in place.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Types, fixture derivation, override validation, placeholder resolution, session binding, `installLlmReplay`, and the plugin export |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; the stream grammar is checked by the LLM companion and derivation tests) |
+
+### Binding and stream flow
+
+`installLlmReplay` loads the ordered scripts, then installs either a routed replay adapter (when `providers` is non-empty) or a catch-all `llm/stream` waterfall listener. Each live `stream()` call is keyed by its calling session id: a new session claims the next unclaimed script (parent first, because it streams before it can delegate), and calls without a `sessionId` share one anonymous session bound to the primary script. The returned `ReplayHandle` carries a disposer for HMR safety and `assertConsumed()`, which throws unless every recorded script bound to a live session and every bound cursor drained.

 # @deepseek-ai/dsh-llm-replay
 
 [English](README.md) | 中文
 
-用于无密钥快照测试的 LLM（大语言模型）回放插件。它根据已记录的**会话 JSONL** fixture（测试前置数据）重建模型流，使测试无需 API 密钥即可针对固定的模型 transcript（文本记录）启动真实 agent（智能体）。配置 `providers` 后，它会注册仅用于回放的适配器，其模型目录可供测试模型发现功能的场景使用；未配置 `providers` 时，它会安装无需模型发现功能的测试所用 catch-all `llm/stream` waterfall（瀑布式事件）。
+## 概述
 
-其消费方包括 ACP（Agent Client Protocol）与 headless `stream-json` 快照套件，以及 Web 浏览器 e2e 流水线。Loader 驱动的套件使用此插件替代真实 LLM 适配器；Web 流水线直接安装它，以保留清理阶段的消费检查句柄。
+`dsh-llm-replay` 让快照测试无需 API 密钥即可运行：它安装一个回放 LLM（大语言模型）适配器，从已记录的会话 JSONL fixture（测试前置数据）重建模型流，使测试针对固定 transcript（文本记录）启动真实 agent（智能体）。fixture 是持久化会话日志的投影——`assistant/chunk` 事件按调用分组为分片序列，显式标记的本地压缩（compaction）调用回放为一条规范流。`replay.override.json` 伴随文件覆盖日志无法重建的情况：任何分片之前就抛出、取消/挂起，或注入重试。实时会话按首次调用顺序绑定到已记录脚本，因此父会话与 subagent 场景各自获得自己的脚本。它是 ACP 与 headless 快照套件以及 Web 浏览器 e2e 流水线的模型来源。
 
-## fixture 的工作方式
+## 目录
 
-fixture 是持久化会话日志（`<scenario>/session.jsonl`）的投影：它保留 header 与每个事件 payload，但省略正文的 `seq`/`time` envelope（打包行使用 `seq0`/`time0`）。回放在解析时恢复连续的 synthetic envelope；同一文件的正文必须全部采用投影行或完整持久化行，不能混用。运行时持久化仍写入完整日志。fixture 的 `assistant/chunk` 事件包含每个 `StreamChunk`，因此按 `(turn, step)` 分组即可重建每次 agent loop（智能体循环）的 `stream()` 调用的分片序列。压缩（compaction）摘要器成功时，日志记录方式有所不同：当 `compaction/summary` 携带 `llmStreamCall: true` 和完整的 `rawOutput` 时，回放会在该事件的位置重建一条规范成功流，其中每个块各使用一对 `block-start`/`block-end`，带上已记录的用量（如有），并以 `stop` 终止。提供方增量的精确切分不属于持久压缩结果。不带该标记的 `rawOutput` 并不意味着发生了本地 LLM 调用，因为模板摘要器和远程摘要器即使未使用此上下文的适配器，也可能保留完整输出。

-因此，录制就是「运行一次真实 agent 并收集 `.jsonl`」，由快照 harness 完成；该插件本身不录制。fixture 的 `request/header` 内容可能被标记化为 `{{system}}`/`{{tools}}`（harness 会在一个场景中固定该内容，并清除其余场景中的内容）；回放不受影响，因为派生过程只读取 `assistant/chunk` 和 `compaction/summary` 事件以及第 0 行的会话 header。
+-----
 
-当回放在带有 `ctx.deepseekLlmApiExtensions` 的组合中提供 `deepseek-official` 时，它会在选中有效脚本条目后、产出第一个分片前准备并接受这些字段。这会复现实时适配器的 2xx 后提交点，使持久接受水位与 SDK 事件通知在录制和回放之间保持一致。回放会提供合成的 `{ messages: [] }` 基础正文：它证明的是接受副作用，而不是已准备字段的字节内容。如果某个扩展的接受操作依赖序列化后的提供方正文，该扩展需要专用 fixture 支持，此回放路径才能表示它。其他提供方路由以及未挂载该可选注册表的组合不受影响。
+<a id="use-this-package"></a>
+## 使用本包
 
-有两种失败模式无法仅根据 `assistant/chunk` 重建：在产生任何分片前直接抛出异常（例如 HTTP 401，此时日志只有 `turn/end {error}` 而没有分片），以及取消或挂起（差异在时序，而非分片内容）。需要这些行为的场景可提供伴随文件（`<scenario>/replay.override.json`）：它可以替换派生脚本（裸 `ReplayEntry[]`），也可以增补派生脚本（`{ patches: [{ at, entry }] }`：保留所有从 JSONL 派生的调用，只替换指定的从 0 开始计数的调用索引；当 `at` 等于派生长度时，则在注入瞬态异常后的重试位置追加一次调用）。补丁索引不得重复。带前缀分片的 `throw` 条目会接受 DeepSeek 请求扩展；零分片 `throw` 默认为 2xx 前不接受，无分片的 2xx 后失败可显式设置 `accepted: true`。文件加载时会校验覆写文档、每个补丁和条目，以及每个分片的判别标签。`hang` 条目可以指定 `readyFile`；当前缀分片到达循环后、开始等待取消前，回放会写入这个空标记，使外部驱动程序无需观察展示层更新即可确定性地取消。
+本包让无密钥测试拥有带固定模型 transcript 的真实 agent：把它挂载到真实 LLM 适配器的位置，指向已记录的 fixture，然后就像模型真的产生了已记录输出那样运行场景。
 
-脚本字符串可以内嵌 `{{fromRequest:<regex>}}`，用来填入静态伴随文件不可能预知的值——例如模型必须原样回填到 `update_goal` 的随机生成 goal id。回放时每个占位符针对实时请求解析：语料是请求消息的所有字符串叶子按换行拼接的结果，取该模式在语料中的最后一次匹配，用其第一个捕获组（无捕获组时用整个匹配）原位替换。模式匹配不到内容、模式非法、占位符未闭合都会明确报错。连续右花括号串的最后两个花括号才是占位符结束符，因此模式可以以花括号量词收尾（如 `[0-9a-f]{4}`），但不能在 `}}` 之后还有后续模式内容。解析作用于所有脚本条目，包括从已记录 JSONL 派生的条目——若录制文本本身合法地含有该字面量标记，需改用不含标记的伴随文件表达。
+### 挂载它
 
-## 嵌套 agent：每会话键控
-
-父 agent 委托给进程内 subagent 的场景会记录多个日志：父会话使用 `session.jsonl`，每个子会话各使用一个日志（`session.1.jsonl` 等）。每个 agent 都在同一上下文中作为独立的 `Session` 运行，因此回放必须为每个 agent 提供各自的脚本。
-
-回放根据发起调用的会话 id 为每次调用建立键（`GenerateOptions.sessionId` 由 agent loop 写入）。实时会话 id 每次运行时都会重新随机生成，绝不会等于记录中的 id，因此实时会话按**首次调用顺序**绑定到已记录脚本：脚本按 header 中的 `createdAt` 排序（父会话在前，因为它必须先开始流式输出才能委托）；第一个发起调用的实时会话取得第一个脚本，下一个新会话取得下一个脚本，以此类推。此后每个会话分别推进自己的游标。没有 `sessionId` 的调用视为一个绑定主脚本的匿名会话。不同实时会话的数量超过已记录脚本数时会明确报错。

+
+本节解释回放插件的设计；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计
+
+回放建立在一个想法之上：投影后的会话日志就是 fixture。`deriveReplayScript` 解析 JSONL header（用于 `id`/`createdAt` 排序事实），并按 `(turn, step)` 键在每次 `finish` 分片处切分 `assistant/chunk` 事件，使每次已记录的 `stream()` 调用成为一条 `chunks` 条目；没有 `finish` 分片的 assistant 分组是 `stream()` 抛出异常的指纹，必须通过 override 伴随文件表达。携带 `llmStreamCall: true` 与完整 `rawOutput` 的 `compaction/summary` 会在该事件位置回放为一条规范成功流。脚本字符串可以内嵌 `{{fromRequest:<regex>}}`；流式输出时每个占位符针对实时请求的字符串叶子解析，取该模式的最后一次匹配，用其第一个捕获组（无捕获组时用整个匹配）原位替换。

-Shared subprocess harness for tests that boot an app and `cordis.yml` through the Cordis Loader. `resolveExampleLaunch` selects local `src` mode (tsx and root tsconfig paths) or CI `lib` mode (plain Node and package exports) from an explicit mode or `DSH_EXAMPLE_MODE`.
+## Summary
 
-`runLoaderSmoke` accepts bin and config paths, optional complete bin arguments, environment overrides, stdin, pre-run setup, and pre-cleanup inspection. It owns the isolated cwd, DSH homes, diagnostics, deadline, termination, EOF, and cleanup; it returns both streams after a zero exit and rejects with both streams on failure.
+`dsh-loader-smoke` runs a real application bin and its `cordis.yml` through the Cordis Loader inside an isolated temporary directory, capturing stdout and stderr, so a smoke test exercises the true composition path — plugin loading, service wiring, and the agent loop — rather than a hand-built test context. `runFixtureTurn` drives one task through the composition's single root agent and returns the final assistant text and accumulated token usage. The package also provides the mode-aware launch resolver (`src` under tsx for zero-build dev, built `lib` under plain Node for CI) shared by package-local subprocess harnesses. It is support-tier test infrastructure, not a product API.
 
-`runFixtureTurn` drives one task through exactly one configured root agent, forwards canonical events after that task reaches the durable inbox, flushes the session, and returns the final assistant text plus accumulated usage. Example-local drivers retain configuration, rendering, and assertion ownership.

+## Use this package
+
+This package boots an application fixture the way an installed consumer would and lets a test watch the result: choose source or built mode, launch the bin with its config from an isolated cwd, and either wait for a clean exit or drive one task through the root agent.
+
+### Booting an application fixture
+
+`runLoaderSmoke` takes bin and config paths, optional complete bin arguments, environment overrides, stdin, pre-run setup, and pre-cleanup inspection. It owns the isolated cwd, DSH homes, diagnostics, deadline, termination, EOF, and cleanup, and returns both streams after a zero exit or rejects with both streams on failure:
+
+```text
+const result = await runLoaderSmoke({
+  label: 'acp-agent',
+  tempDirPrefix: 'acp-smoke-',
+  binScript: '/abs/path/to/src/bin.ts',
+  configPath: '/abs/path/to/cordis.yml',
+  tsconfigPath: '/abs/path/to/tsconfig.json',
+})
+```
+
+Set `expectedExitCode` when the scenario pins a designed failure surface — a one-shot turn ending in an error result — and a run that exits any other way, including succeeding, still fails the smoke.
+
+### Driving a fixture turn
+
+`runFixtureTurn(ctx, options)` drives one task through exactly one configured root agent: it waits for the task to reach the durable inbox, forwards canonical events to your observer, flushes the session, and returns the final assistant text plus accumulated usage. Example-local drivers keep configuration, rendering, and assertion ownership.
+
+### Source or built mode
+
+`resolveExampleLaunch` picks the artifact an example bin boots from. `src` mode runs the bin under tsx with `TSX_TSCONFIG_PATH` set, so workspace imports resolve through the tsconfig `paths` map — the zero-build dev path. `lib` mode runs the built `lib/` bin under plain Node, so bare package plugins resolve through real package `exports`, exactly as an installed consumer resolves them. The mode comes from an explicit value or `DSH_EXAMPLE_MODE` (CI sets `lib`, dev leaves it unset); anything else fails loud.
+
+### What can go wrong
+
+- **The process never exits** — the smoke enforces a deadline and reports the captured streams in the failure; a faulty fixture that spawns its own process tree can outlive the smoke and needs external cleanup.
+- **Built mode needs a prior build** — run `pnpm run build` before selecting `DSH_EXAMPLE_MODE=lib`; the owning package manifest must also declare every package named by the config.
+- **Captured output is bounded by execa's default 100 MB `maxBuffer`** — a runaway child is terminated at that ceiling rather than at a smoke-chosen budget.

+
+This section explains the design of the harness; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design
+
+The harness is built on one separation: the smoke runs in a child process under an isolated world, and the test process only observes and asserts. `runLoaderSmoke` creates a temporary cwd, prepares world state there, spawns the resolved bin with isolated DSH homes (`DSH_HOME`, `DSH_AGENTS_HOME` under the temp cwd), closes stdin immediately, and awaits a clean exit within the deadline before inspecting and cleaning up on every outcome. `runFixtureTurn` stays in-process: it looks up the composition's single root agent, follows the task from its durable inbox receipt through whole-agent idle, sums per-step usage, and flushes the session before returning.

+## 使用本包
+
+本包以已安装消费方的方式启动应用 fixture，并让测试观察结果：选择源模式或构建模式，从隔离 cwd 用其配置启动可执行文件，然后要么等待干净退出，要么让一项任务通过根 agent。
+
+### 启动应用 fixture
+
+`runLoaderSmoke` 接受可执行文件与配置路径、可选的完整可执行文件参数、环境覆盖、标准输入、运行前准备与清理前检查。它负责隔离工作目录、DSH 主目录、诊断、截止时间、终止、EOF 与清理；进程以零状态退出后返回两个流，失败时则拒绝并附带两个流：
+
+```text
+const result = await runLoaderSmoke({
+  label: 'acp-agent',
+  tempDirPrefix: 'acp-smoke-',
+  binScript: '/abs/path/to/src/bin.ts',
+  configPath: '/abs/path/to/cordis.yml',
+  tsconfigPath: '/abs/path/to/tsconfig.json',
+})
+```
+
+当场景固定一个设计好的失败面——例如一次性轮次以错误结果结束——时设置 `expectedExitCode`；以任何其他方式退出（包括成功退出）都会使冒烟测试失败。
+
+### 驱动 fixture 轮次
+
+`runFixtureTurn(ctx, options)` 让一项任务通过恰好一个已配置的根 agent：它等待任务进入持久收件箱，把规范事件转发给你的观察器，刷写会话，并返回最终 assistant 文本与累计用量。示例本地的 driver 继续负责配置、渲染与断言。
+
+### 源模式或构建模式
+
+`resolveExampleLaunch` 选择示例可执行文件从哪个产物启动。`src` 模式在 tsx 下运行可执行文件并设置 `TSX_TSCONFIG_PATH`，使工作区导入通过 tsconfig `paths` 映射解析——这是零构建开发路径。`lib` 模式在普通 Node 下运行构建后的 `lib/` 可执行文件，使裸包插件通过真实包 `exports` 解析，与已安装消费方的解析方式完全一致。模式来自显式值或 `DSH_EXAMPLE_MODE`（CI 设置 `lib`，开发时保持未设置）；其他任何值都会明确报错。
+
+### 可能出什么问题
+
+- **进程永不退出**——冒烟测试强制执行截止时间，并在失败信息中报告捕获的流；生成自身进程树的有故障 fixture（测试前置数据）可能比冒烟测试存活更久，需要外部清理。
+- **构建模式需要事先构建**——选择 `DSH_EXAMPLE_MODE=lib` 前先运行 `pnpm run build`；拥有该配置的包 manifest 还必须声明配置中点名的每个包。
+- **捕获输出受 execa 默认 100 MB `maxBuffer` 约束**——失控子进程在该上限处被终止，而不是在冒烟测试自选的预算处。

-Session-log snapshot support for the keyless snapshot tier (`pnpm run test:snapshot`, [testing policy](../../../docs/testing.md)). Transport-neutral manifests, typed identity redaction, normalization, write-back, and fixture invariants are shared by the headless, SDK, ACP, and Web adapters. Their tests launch or compose the shipped `dsh` profile surface; the support package does not provide another application entrypoint.
+## Summary
 
-Every recorded-session directory carries a closed `snapshot.yml` manifest. `scenario` repeats the directory name for move diagnostics, `profile` names the shipped `dsh` controller, `composition` groups scenarios under one profile patch and request-header pin, `recording` distinguishes live-recordable sessions from deliberately authored scripts, and `header` records pin and sidecar ownership. `replay`, `platform`, `permission`, `environment`, `workspace`, and `input` hold only facts the completed session cannot reconstruct; inline attachment bytes are the standard exceptional input. A directory owns its local `session.jsonl` unless `session.source` names another scenario's read-only canonical recording. Unknown fields, JavaScript YAML tags, malformed names and indexes, absolute paths, and platform-specific separators fail during collection.
+`dsh-session-snapshot` provides the shared support behind keyless recorded-session tests (`pnpm run test:snapshot`): closed manifests, typed identity redaction, normalization, workspace comparison, fixture guards, and protocol adapters for headless, SDK, ACP, and Web owners. The ACP adapter launches the tested profile as a real subprocess, drives a deterministic input script, and registers the complete record, replay, and refresh suite. Every scenario owns enough committed evidence to prove model-visible output and filesystem effects without trusting the agent's report. The package entry imports vitest and is therefore available only inside a vitest run.
 
-`workspace/` contains scenario-local initial files. A scenario that changes its cwd sets `workspace.final: true` and commits the complete user-visible result under `workspace.expected/`; an otherwise-empty result keeps an ignored `.empty` marker so Git retains the directory. Replay compares files, binary bytes, links, and empty directories after the controlled interface settles. Record and refresh never rewrite this independent expected state, so a transcript that merely claims a mutation still fails.
+## Table of Contents
 
-Committed sessions use typed first-seen tokens such as `{{session:1}}`, `{{message:4}}`, and `{{approval:1}}`. One map covers the primary and every child so parent links, relays, and repeated message identities stay test-visible. Arbitrary user and tool prose is unchanged unless it contains a value already identified by a typed field. Request system prompts and tool schemas never remain in session JSONL; each composition/header class has one structural pin, while identical prompt or schema bytes reference one readable sidecar owner.

-The current ACP adapter has four importable layers:
+-----
 
-- **`launchAcpTestAgent` (launcher)** — boots a source entry under tsx or a built `lib` entry under plain Node from a supplied cwd, connects the SDK client over a raw-byte stdout tee, collects session updates and stderr, surfaces asynchronous spawn failures through startup, fails closed on unhandled permission requests, and owns graceful or signalled shutdown. Product suites name a `dsh` profile: the launcher passes the base and selected scenario patches through `--patch`, selects the scenario's sibling `*cordis.snapshot.yml` in replay, and materializes temporary copies whose relative plugin modules become absolute file URLs. Test-only fake bins may omit the profile and retain their own config grammar. Shutdown waits for process exit, inherited stdio closure, and ACP parser exhaustion before resolving or propagating a child error, so captures are complete and callers can remove owned paths after either outcome.
-- **`runScenario` (harness)** — drives ACP JSON-RPC stdio from a deterministic `input.json` script through the launcher, tees raw stdout for the expected-output and purity checks, and harvests every persisted raw JSONL session log (parent and subagent children, primary-first) after graceful stdin EOF. `AgentUnderTest` supplies absolute `binScript`, optional `libBinScript`, `configPath`, and `tsconfigPath` paths because the subprocess cwd is outside the repo; `workspaceParent` may move the generated child cwd from the platform temp directory when that grant is itself under test. Startup failures preserve captured agent stderr in the rejected diagnostic.
-- **Normalizers** — pure functions turning captured surfaces into stable text or portable fixtures: `normalizeStdout` (JSON-RPC ids → first-seen sequence; UUIDs and every native/JavaScript filesystem spelling of the generated cwd → tokens, longest-first; cwd-rooted separators selected as canonical `/` or host-native; doubles as the stdout-purity check), `normalizeSessionLog` (sequence envelopes retained, times zeroed, the same cwd-path policy), `normalizeSessionSnapshot` (session-log normalization followed by request-header scrubbing and body-envelope projection), `tokenizeSessionFixtureCwd` (the generated workspace and its filesystem aliases → one canonical `{{cwd}}`, including an already-tokenized macOS `/private` alias; authored temp paths unchanged), `scrubSystemPrompts` (prompt text → `{{system}}`), `scrubToolSchemas` (schema bulk → `{{tools}}`), `scrubRequestHeaders` (all header bulk → `{{system}}`/`{{tools}}`/`{{messagePrefix}}` outside each pin, structure kept — [pinned-header Agent Note](../../../.agents/notes/archived/testing/2026-07-06-pin-request-header-content-in-one-scenario.md)), and `stabilizeFixtureMessageIds` (committed UUIDs carried into unchanged, mutually unique messages by structurally rewriting only complete surface and durable-inbox message ID fields across any recorder's fixture-ready parent/child logs).
-- **`defineAcpSnapshotSuite` (factory)** — registers the whole describe/it tree for a scenario table: per-scenario expected-output and re-persisted-log comparisons, record/refresh fixture write-back, rejection of structured `UNKNOWN_TOOL` results, a tokenized pin per header class composed with independently shared `system-prompt.expected.md` and `tool-schemas.expected.json` sidecars, and a live uniformity guard. Its fixture guards reject orphan scenario dirs, missing files, multiple pins for one class, duplicate sidecar content, noncanonical macOS-prefixed cwd tokens, unscrubbed JSONL headers, and malformed pinning headers. Before record or refresh writes fixtures, an unchanged complete message retains its committed UUID only when both its ID and identity-free fingerprint are unique across the scenario's fixture-ready parent/child logs; the session package's authoritative surface-type predicate selects surface carriers, correlated `agent/inbox/spliced` copies join the same mapping, and only validated `id` fields in those carriers are rewritten. New, changed, malformed, and graph-ambiguous messages keep fresh UUIDs. Refresh evaluates fresh leaves with the harvested run's ids, cwd, and every cwd alias, then reuses normalized-equivalent leaves only when the complete logical-record layout aligns and volatile string replacements form a bijection; complete message IDs in surface or inbox carriers are excluded because the later structural pass owns them, ambiguous logs keep fresh strings, and fresh semantic values remain authoritative. It also expands packed timing envelopes before aligning event times, so switching between packed and unpacked layouts cannot shift later records. A newly inserted `session/title` receives its preceding event's time so feature-driven insertions do not churn the remainder of a fixture. Each scenario directory's `session.jsonl` plus contiguous `session.<n>.jsonl` siblings are the ordered primary/child inventory; the scenario table does not duplicate their count. Must be called at vitest collection time.
+<a id="use-this-package"></a>
+## Use this package
 
-Committed session fixtures retain their complete session header and event payloads but omit ordinary `seq`/`time` and packed-row `seq0`/`time0` envelopes. Replay synthesizes those envelopes in memory; runtime persistence remains unchanged. Fixtures also use canonical packed rows; the [temporary repository migrator](../../../scripts/migrate-packed-session-fixtures.ts) (`pnpm run migrate:packed-session-fixtures`) rewrites older fixture layouts, and its [removal proposal](../../../.agents/notes/proposed/process/2026-07-26-remove-packed-session-fixture-migrator.md) owns its deletion.
+This package turns a shipped profile scenario into a keyless snapshot suite: write a scenario table and a fixtures directory, call the matching adapter once, and the kit owns launching or composing the profile, driving the scenario, comparing normalized output, and guarding the committed fixtures.

-A scenario booting a differently composed profile sets its own `configPath` patch (its basename still ends in `cordis.yml`, so the launcher finds the sibling `*cordis.snapshot.yml`) and, when that composition changes the request header, its own `headerClass` with its own pinning scenario; the top-level profile corpora contain the current templates. Default generated workspaces are stored in session fixtures as `{{cwd}}` so platform temp roots and random basenames do not affect recordings; `workspaceParent` moves the generated cwd outside the platform temp area when temporary-directory grants are themselves under test, keeps that explicit path in the fixture, and remains parent-owned while the harness removes only the generated child. A scenario's committed `workspace/` is copied into that child first, then `prepareWorkspace` runs against the generated cwd before the agent starts. Reserve this hook for fixtures Git cannot represent portably, keep ordinary seeds in `workspace/`, and pair it with `posixOnly` when the generated paths are invalid on Windows.
+Each recorded-session directory carries a closed `snapshot.yml` manifest plus its `session.jsonl` and contiguous `session.<n>.jsonl` child logs. The manifest names the scenario, shipped profile, composition/header class, recording source, and only the replay, platform, permission, environment, workspace, or input facts the completed session cannot reconstruct. The adapter registers expected-output, session-log, and optional `workspace.expected/` comparisons; guards reject orphan directories, missing files, absolute paths, malformed manifests, and platform-specific separators.
 
-A pin owns its generated `system-prompt.expected.md` or `tool-schemas.expected.json` by default; `systemPromptSource` and `toolSchemasSource` name another pin when the complete corresponding sequence is identical, so each distinct version is committed once. The pin's `session.jsonl` stores `"system":"{{system}}","tools":"{{tools}}"` while retaining config, reason, and any model-visible prefix. A pin with legitimate mid-run header changes declares `expectedHeaderChanges`; a shared source must declare the same count, and record/refresh rejects claimants that generate different bytes.
+`normalizeSessionSnapshot` retains the complete session header and event payloads but omits ordinary `seq`/`time` and packed-row `seq0`/`time0` envelopes from committed fixtures after normalizing paths and scrubbing request headers. Replay synthesizes the envelopes in memory, while runtime persistence continues to write complete logs. Fixtures use canonical packed rows; the [temporary repository migrator](../../../scripts/migrate-packed-session-fixtures.ts) (`pnpm run migrate:packed-session-fixtures`) rewrites older layouts, and its [removal proposal](../../../.agents/notes/proposed/process/2026-07-26-remove-packed-session-fixture-migrator.md) owns its deletion.
 
-A child session whose own scope composes a different request declares it per fixture index: `pinsChildToolSchemas` moves that child's tool sequence into `tool-schemas.<n>.expected.json`, and `pinsChildSystemPrompts` moves its prompt into `system-prompt.<n>.expected.md`. Each names the `session.<n>.jsonl` fixture it describes, leaves every other request-header field to the class pin, and requires its sidecar to exist exactly when declared. A child prompt sidecar must also differ from its class pin, so a redundant copy fails instead of drifting. A continuable child carrying the scope-local `report` tool and its guidance section is the shipped case for both.
+### Record, replay, and refresh
 
-Every scenario compares `stdout.expected.jsonl` with cwd-rooted separators canonicalized to `/`. On Windows, `pinsNativeWindowsStdout` additionally compares the complete `stdout.expected.windows.jsonl` after the shared expected output and requires that sidecar exactly when enabled. A scenario requiring a non-Windows host declares `posixOnly`, which skips its run test on Windows while the fixture guards keep covering its committed files everywhere; examples include POSIX process semantics (e.g. cancelling a live bash call kills a detached process group) and generated paths Windows cannot represent. A scenario whose composition needs a usable `pwsh` declares `pwshOnly`; the caller-supplied `hasPwsh` probe (the shipped acp-agent suite follows the executor's own resolution, so Program Files installs count) skips the run test when no usable `pwsh` resolves while the fixture guards keep covering its committed files everywhere.
+`pnpm run test:snapshot:record` calls the live LLM and rewrites recorded model fixtures; `pnpm run test:snapshot:refresh` stays keyless, runs the replay overlay, and rewrites stdout, comparable session-log expected outputs, and owned prompt and tool-schema sidecars from committed model scripts. Each composition owner keeps its replay patch beside its live patch; top-level `snapshots/` owns session-driven scenarios, while other expected outputs stay beside their owning package. [`dsh-llm-replay`](../llm-replay/README.md) serves the recorded streams selected through `DSH_SNAPSHOT_*` environment values.
 
-Each composition owner ships a `cordis.snapshot.yml` replay patch next to its live patch. The launcher applies the live base patch and the selected replay sibling under `DSH_SNAPSHOT=replay` ([single-source replay config Agent Note](../../../.agents/notes/archived/testing/2026-07-04-single-source-acp-replay-config.md)); [`dsh-llm-replay`](../llm-replay/README.md) serves fixtures named by the `DSH_SNAPSHOT_*` environment values. `pnpm run test:snapshot:record` calls the live LLM and rewrites the recorded scenarios' model fixtures; `pnpm run test:snapshot:refresh` stays keyless, runs the replay patch, and rewrites stdout, comparable session-log expected outputs, and owned prompt and tool-schema sidecars from the committed model scripts. Fixture roles, record/replay/refresh semantics, and scenario-table fields are documented on `Scenario` and in the [snapshot Agent Note](../../../.agents/notes/implemented/testing/2026-06-19-acp-snapshot-tests.md).
+### Pinning request headers
 
-Constraints: `suite.ts` and `harness.ts` import vitest (the harness polls its durable-boundary waits through `vi.waitFor`), so the package entry is importable only inside a vitest run (the launcher and normalizers have no such dependency but ship from the same entry). The launcher and suite factory are ACP-specific by design — the launcher speaks the SDK's `ClientSideConnection` — while the normalizers are transport-neutral session-log/text helpers also consumed by the JSON-RPC and Web snapshot recorders. Input scripts cover initialization, fresh-session creation, shorthand text prompts, exact structured ACP prompt blocks, cancellation, expected RPC failures, and durable turn-boundary waits. Permission round-trips are a FIFO queue of option-kind selections (`allow_once`, `reject_once`, …) mapped to the agent-issued `optionId`; an absent or exhausted queue answers `cancelled`, and an unoffered kind rejects the run.
+A pin owns its generated `system-prompt.expected.md` or `tool-schemas.expected.json` sidecar by default; `systemPromptSource` and `toolSchemasSource` name another pin when the complete corresponding sequence is identical, so each distinct version is committed once. The pin's `session.jsonl` stores `"system":"{{system}}","tools":"{{tools}}"` while retaining config, reason, and any model-visible prefix. A child session whose own scope composes a different request declares it per fixture index with `pinsChildToolSchemas` and `pinsChildSystemPrompts`. A scenario that changes the request header mid-run declares `expectedHeaderChanges`.
 
+### Platform and composition variants
+
+A scenario requiring a non-Windows host declares `posixOnly`, which skips its run test on Windows while the fixture guards keep covering its committed files everywhere; a scenario whose composition needs a usable `pwsh` declares `pwshOnly`. `workspaceParent` moves the generated child cwd outside the platform temp directory when temporary-directory grants are themselves under test; a scenario's committed `workspace/` is copied into that child first, then `prepareWorkspace` runs against the generated cwd before the agent starts. Default generated workspaces are stored in session fixtures as `{{cwd}}`, so platform temp roots and random basenames do not affect recordings.
+
+### What can go wrong
+
+- **A fixture guard rejects the committed files** — orphan scenario dirs, missing files, multiple pins for one header class, duplicate sidecar content, unscrubbed JSONL headers, and malformed pinning headers all fail the suite before comparisons run.
+- **The session harvest needs raw JSONL mode** — snapshot configs set the JSONL backend's `compression: 'none'`; compressed JSONL and SQLite compositions have no snapshot-harvest path.
+- **Built mode needs current artifacts** — run `pnpm run build` before selecting `DSH_EXAMPLE_MODE=lib`; source mode remains the zero-build path.

+
+This section explains the design of the kit; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design
+
+The shared core owns manifests, workspace setup/comparison, typed identity mapping, normalizers, and fixture invariants. The ACP adapter adds four composable layers: launcher, scenario harness, normalizers, and suite factory. `launchAcpTestAgent` boots a source profile under tsx or a built `lib` profile under plain Node, connects the SDK client over a raw-byte stdout tee, collects session updates and stderr, fails closed on unhandled permission requests, and owns shutdown. `runScenario` drives ACP JSON-RPC stdio and harvests every persisted raw JSONL session log. The pure normalizers replace cwd paths and typed identities with stable tokens, zero times, and scrub request-header bulk. `defineAcpSnapshotSuite` registers comparisons, fixture write-back, and the live uniformity guard.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/launcher.ts`](src/launcher.ts) | Subprocess/client launcher and shutdown ownership |
+| [`src/harness.ts`](src/harness.ts) | Scripted scenario driver and session-log harvest |
+| [`src/manifest.ts`](src/manifest.ts) | Closed `snapshot.yml` schema, collection, and ownership rules |
+| [`src/identity.ts`](src/identity.ts) | Typed first-seen identity tokenization across parent and child logs |
+| [`src/normalize.ts`](src/normalize.ts) | Pure normalizers and scrubbing helpers |
+| [`src/workspace.ts`](src/workspace.ts) | Scenario workspace setup and complete expected-state comparison |
+| [`src/suite.ts`](src/suite.ts) | Scenario-table suite factory, fixture guards, record/refresh write-back |
+| [`src/index.ts`](src/index.ts) | Package entry re-exporting the four layers |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; consuming test suites exercise the kit) |
+
+### Data flow
+
+A scenario runs the agent under the launcher, feeds it the input script through the harness, and captures stdout plus the persisted logs. The normalizers canonicalize those captures — ids to first-seen sequence, generated cwd to `{{cwd}}`, header bulk to `{{system}}`/`{{tools}}` — so recorded and fresh runs compare structurally. The factory then compares normalized stdout and re-persisted logs against committed fixtures, or writes them back in record/refresh mode, and its guards reject malformed or drifting fixtures before any comparison result is trusted.

-无密钥快照层（`pnpm run test:snapshot`，见[测试策略](../../../docs/testing.zh.md)）的会话日志快照支持。与传输无关的 manifest、带类型身份脱敏、规范化、回写和 fixture（测试前置数据）不变量由 headless、SDK、ACP（Agent Client Protocol）和 Web 适配器共享。对应测试启动或组装随附的 `dsh` profile 表层；本支持包不提供另一个应用入口。
+## 概述
 
-每个录制会话目录都包含一个封闭的 `snapshot.yml` manifest。`scenario` 重复目录名以便诊断移动，`profile` 指名随附的 `dsh` 控制器，`composition` 把场景归入同一组 profile patch 与请求头 pin，`recording` 区分可通过真实模型录制的会话和特意手写的脚本，`header` 记录 pin 与 sidecar 的所有权。`replay`、`platform`、`permission`、`environment`、`workspace` 和 `input` 只保存已完成会话无法重建的事实；内联附件字节是标准的例外输入。除非 `session.source` 指向另一个场景的只读规范录制，否则目录拥有本地 `session.jsonl`。收集期间会拒绝未知字段、JavaScript YAML tag、格式错误的名称和索引、绝对路径及平台专用分隔符。
+`dsh-session-snapshot` 提供无密钥已记录会话测试（`pnpm run test:snapshot`）背后的共享支持：封闭 manifest、类型化身份脱敏、规范化、workspace 比较、fixture 保护，以及 headless、SDK、ACP 与 Web owner 使用的协议适配器。ACP 适配器以真实子进程启动被测 profile，驱动确定性输入脚本，并注册完整的录制、回放与刷新套件。每个场景都提交足够证据来证明模型可见输出与文件系统效果，不依赖 agent 自述。包入口会导入 vitest，因此只能在 vitest 运行中使用。
 
-`workspace/` 保存场景本地的初始文件。会改变 cwd 的场景设置 `workspace.final: true`，并在 `workspace.expected/` 下提交完整的用户可见结果；结果为空时使用被忽略的 `.empty` 标记，使 Git 保留该目录。受控接口结束后，回放会比较文件、二进制字节、符号链接和空目录。record 与 refresh 绝不改写这份独立预期，因此只在 transcript 中声称完成变更的场景仍会失败。
+## 目录
 
-提交的会话使用 `{{session:1}}`、`{{message:4}}` 和 `{{approval:1}}` 等按首次出现编号的带类型 token。主会话及其所有子会话共用一张映射，因此父级链接、中继消息和重复消息身份仍然可测试。任意用户或工具正文保持不变，除非其中包含已由带类型字段识别的同一值。请求系统提示词和工具 schema 绝不保留在会话 JSONL 中；每个组合与请求头类别有一个结构 pin，而字节相同的提示词或 schema 引用同一个可读 sidecar 所有者。

-当前 ACP 适配器包含四个可单独导入的层：
+-----
 
-- **`launchAcpTestAgent`（启动器）**：从指定 cwd 在 tsx 下启动源码入口，或在普通 Node 下启动已构建 `lib` 入口；通过原始字节 stdout tee 连接 SDK 客户端，收集会话更新和 stderr，在启动阶段报告异步 spawn 失败，默认拒绝未处理的权限请求，并负责优雅或带信号关闭。产品套件指定一个 `dsh` profile：启动器通过 `--patch` 传入基础 patch 与所选场景 patch，在 replay 时选择场景同级的 `*cordis.snapshot.yml`，并把相对插件模块改写成绝对 file URL 后物化为临时副本。测试专用 fake bin 可以省略 profile 并保留自己的配置语法。关闭会等待进程退出、继承 stdio 关闭和 ACP parser 耗尽，然后才完成关闭或传播子级错误，使捕获内容完整，且调用方可在任一结果后移除自有路径。
-- **`runScenario`（harness）**：通过启动器从确定性 `input.json` 脚本驱动 ACP JSON-RPC stdio，将原始 stdout tee 给预期输出和纯度检查，并在优雅 stdin EOF 后收集每个持久化原始 JSONL 会话日志（父会话和 subagent 子会话，主会话优先）。`AgentUnderTest` 提供绝对 `binScript`、可选 `libBinScript`、`configPath` 和 `tsconfigPath` 路径，因为子进程 cwd 位于仓库外。当生成子级 cwd 的授权本身是测试对象时，`workspaceParent` 可以将它从平台临时目录移出。启动失败会在拒绝诊断中保留已捕获 agent stderr。
-- **规范化器**：将已捕获内容转换为稳定文本或可移植 fixture 的纯函数：`normalizeStdout`（JSON-RPC id → 首次出现序列；UUID 以及生成 cwd 的每种原生／JavaScript 文件系统写法 → token，按最长优先；根据 cwd 的分隔符选择规范 `/` 或宿主原生形式；同时作为 stdout 纯度检查）、`normalizeSessionLog`（保留序号 envelope、将时间归零，并使用同一 cwd 路径策略）、`normalizeSessionSnapshot`（依次执行会话日志规范化、request header 清理和正文 envelope 投影）、`tokenizeSessionFixtureCwd`（生成的 workspace 及其文件系统别名，包括已进行 token 化的 macOS `/private` 别名 → 单一规范 `{{cwd}}`；手工编写的临时路径保持不变）、`scrubSystemPrompts`（提示词文本 → `{{system}}`）、`scrubToolSchemas`（schema bulk → `{{tools}}`）、`scrubRequestHeaders`（每个 pin 之外的所有 header bulk → `{{system}}`/`{{tools}}`/`{{messagePrefix}}`，保留结构；见[header 固定 Agent Note](../../../.agents/notes/archived/testing/2026-07-06-pin-request-header-content-in-one-scenario.md)）和 `stabilizeFixtureMessageIds`（针对任意录制器已准备写入 fixture 的父级/子级日志，通过结构化方式仅改写 surface 和持久 inbox 中完整消息的 ID 字段，将已提交 UUID 带入未变化且双向唯一匹配的消息）。
-- **`defineAcpSnapshotSuite`（工厂）**：为场景表注册完整 describe/it 树：每场景预期输出与重新持久化日志比较、录制/刷新 fixture 回写、拒绝结构化 `UNKNOWN_TOOL` 结果、每个 header 类别一个 token 化 pin（由可独立共享的 `system-prompt.expected.md` 和 `tool-schemas.expected.json` 伴随文件组合而成），以及实时一致性保护。其 fixture 保护会拒绝遗留场景目录、缺失文件、一个类别包含多个 pin、重复的伴随文件内容、带非规范 macOS 前缀的 cwd token、未擦除的 JSONL header，以及格式错误的 pin header。在录制或刷新模式写入 fixture 前，仅当一条未变化完整消息的 ID 及其去除身份后的指纹在场景可写入 fixture 的父级/子级日志中均唯一时，该消息才会保留已提交的 UUID；会话包的权威 surface 类型谓词负责选择 surface 载体，与其关联的 `agent/inbox/spliced` 副本也纳入同一映射，且仅改写这些载体中通过验证的 `id` 字段。新增、发生变化、格式错误以及图关系存在歧义的消息保留本次生成的 UUID。刷新会使用收集所得本次运行的 id、cwd 及全部 cwd 别名评估本次生成的叶值；只有完整逻辑记录布局对齐且易变字符串替换形成双射时，才会复用归一化后等价的叶值；surface 或 inbox 载体中的完整消息 ID 不参与此路径，因为后续结构化处理负责这些 ID；有歧义的日志保留本次生成的字符串，而本次生成的语义值仍为权威数据。它还会在对齐事件时间前展开打包时序 envelope，因此切换打包/非打包布局无法移动后续记录。新插入的 `session/title` 使用前一个事件的时间，因此功能驱动的插入不会扰动 fixture 余下部分。每个场景目录的 `session.jsonl` 和连续 `session.<n>.jsonl` 同级文件构成有序的主会话／子会话清单；场景表不重复其数量。必须在 vitest 收集时调用。

-启动不同 profile 组合的场景会设置自己的 `configPath` patch（其 basename 仍以 `cordis.yml` 结尾，使启动器可找到同级 `*cordis.snapshot.yml`）；当该组合改变请求 header 时，还会设置自己的 `headerClass` 和 pin 场景，顶层各 profile 语料包含当前模板。默认生成的 workspace 在会话 fixture 中存储为 `{{cwd}}`，使平台临时根目录和随机 basename 不影响录制结果；当临时目录授权自身待测时，`workspaceParent` 将生成 cwd 移出平台临时区域，在 fixture 中保留该显式路径，并仍归父级所有，而 harness 只移除生成的子级。场景签入的 `workspace/` 会先复制到该子级，随后 `prepareWorkspace` 在 agent 启动前针对生成 cwd 运行。此 hook 仅用于 Git 无法跨平台表示的 fixture；普通种子应留在 `workspace/` 中，而生成路径在 Windows 上无效时还必须搭配 `posixOnly`。
+每个已记录会话目录携带封闭的 `snapshot.yml` manifest，以及自身的 `session.jsonl` 与连续的 `session.<n>.jsonl` 子会话日志。manifest 指名场景、随附 profile、组合／header 类别、录制来源，以及已完成会话无法重建的 replay、平台、权限、环境、workspace 或输入事实。适配器注册预期输出、会话日志与可选 `workspace.expected/` 比较；保护会拒绝遗留目录、缺失文件、绝对路径、畸形 manifest 与平台专用分隔符。
 
-每个 pin 默认拥有其生成的 `system-prompt.expected.md` 或 `tool-schemas.expected.json`；当完整的对应序列相同时，`systemPromptSource` 和 `toolSchemasSource` 指定另一个 pin 作为来源，因此每个不同版本只提交一次。该 pin 的 `session.jsonl` 存储 `"system":"{{system}}","tools":"{{tools}}"`，同时保留配置、原因和任何模型可见前缀。具有合法运行中 header 变更的 pin 声明 `expectedHeaderChanges`；共享来源必须声明相同的 header 变更数量，录制/刷新会拒绝生成不同字节的共享引用方。

-自身作用域组合出不同请求的 child 会话按 fixture 索引单独声明：`pinsChildToolSchemas` 把该 child 的工具序列移入 `tool-schemas.<n>.expected.json`，`pinsChildSystemPrompts` 把其提示词移入 `system-prompt.<n>.expected.md`。两者都指名自己描述的 `session.<n>.jsonl` fixture，其余请求 header 字段仍归类别 pin 所有，并要求 sidecar 恰好在声明时存在。child 提示词 sidecar 还必须与其类别 pin 不同，因此冗余副本会直接失败，而不会悄悄漂移。携带作用域局部 `report` 工具及其指引 section 的可继续 child 是两者的随附用例。
+### 录制、回放与刷新
 
-每个场景都比较 `stdout.expected.jsonl`，其中以 cwd 为根的分隔符规范化为 `/`。在 Windows 上，`pinsNativeWindowsStdout` 还会在共享预期输出之后比较完整 `stdout.expected.windows.jsonl`，并且仅在启用时要求存在该伴随文件。需要非 Windows 主机的场景声明 `posixOnly`，在 Windows 上跳过运行测试，但 fixture 保护仍在所有平台覆盖其已提交文件；示例包括 POSIX 进程语义（例如取消正在运行的 bash 调用会终止一个已脱离的进程组）和 Windows 无法表示的生成路径。组合需要可用 `pwsh` 的场景声明 `pwshOnly`；调用方提供的 `hasPwsh` 探测（随附的 acp-agent 套件遵循执行器自身的解析，因此 Program Files 安装也计入）在解析不到可用 `pwsh` 时跳过运行测试，而 fixture 保护仍处处覆盖其已提交文件。

+- **构建 mode 需要当前产物**——选择 `DSH_EXAMPLE_MODE=lib` 前先运行 `pnpm run build`；源 mode 仍是零构建路径。

+本节解释工具包的设计；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计
+
+共享核心拥有 manifest、workspace 设置／比较、类型化身份映射、规范化器与 fixture 不变式。ACP 适配器增加四个可组合层：启动器、场景 harness、规范化器与套件工厂。`launchAcpTestAgent` 在 tsx 下启动源码 profile，或在普通 Node 下启动已构建 `lib` profile，通过原始字节 stdout tee 连接 SDK 客户端，收集会话更新与 stderr，默认拒绝未处理的权限请求，并负责关闭。`runScenario` 驱动 ACP JSON-RPC stdio，并收集每个持久化原始 JSONL 会话日志。纯规范化器把 cwd 路径与类型化身份变为稳定 token，将时间归零，并擦除请求 header bulk。`defineAcpSnapshotSuite` 注册比较、fixture 回写与实时一致性保护。

+### 数据流
+
+场景在启动器下运行 agent，通过 harness 向它喂入输入脚本，并捕获 stdout 与持久化日志。规范化器把捕获内容规范化——id 转为首次出现序列、生成 cwd 转为 `{{cwd}}`、header bulk 转为 `{{system}}`/`{{tools}}`——使已录制与本次运行可以结构化比较。随后工厂把规范化 stdout 与重新持久化日志同已提交 fixture 比较，或在录制/刷新模式下回写它们；其保护在任何比较结果被采信之前就拒绝畸形或漂移的 fixture。

-The model-facing todo capability. It is a single **product** package because one agent session owns the list; there is no replaceable provider contract.
+## Summary
+
+The todo group gives agents a session-level task list to plan with: add tasks, mark them in progress, and check them off, with the same list persisting across turns and reopened sessions. It is one product package that provides the `todo_write` tool; the list belongs to the agent session that created it, and each update replaces the whole list. Interactive hosts show the standing plan from the list, while the group itself ships no UI.

 # @deepseek-ai/dsh-tool-todo
 
 English | [中文](README.zh.md)
 
-The model-facing `todo_write` tool: the agent's whole task list, replaced wholesale on each call.
+## Summary
 
-## What it does
+`dsh-tool-todo` gives the agent a structured task list to plan with: break multi-step work into concrete tasks, mark the task you are working on, and check tasks off as they finish. The list survives across turns and reopened sessions, so the agent and the UI always see the latest plan. One configuration flag decides whether several tasks may be in progress at once, for agents that run work in parallel. Use it wherever an agent should keep a visible task list; each update replaces the whole list, and only the owning agent session can change it.
 
-Registers one tool, `todo_write(todos: [{ content, status }])`, on `ctx.tools`. The model sends the ENTIRE list every call — there are no partial updates or per-item edits. Each call appends a `todo/write` event (the full list snapshot) to the calling agent's session log via `agent.session.append('todo/write', { todos })`; the current list is the most recent such event (last-write-wins on replay).
+## Table of Contents
 
-`status` is one of `pending`, `in_progress`, or `completed`.

+- [Further Exploration](#further-exploration)
+- [Model Experience](#model-experience)
+- [Known Limitations and Deferred Work](#known-limitations-and-deferred-work)
+- [Dev Note](#dev-note)
 
-## Single owner
+-----
 
-The list belongs to the ONE agent session that called the tool. There is no subagent/shared/swarm scope: a non-agent caller (no `exec.agent`) has nowhere to write the list and is rejected. This is a deliberate scope limit — see the Agent Note.
+<a id="use-this-package"></a>
+## Use this package
 
-## Configuration
+Use this package when you want the agent to maintain a visible task list while it works: plan multi-step work, show what is active, and record completion. Mounting it with the parallelism flag is the only setup; the agent then updates the list through its own planning tool whenever the plan changes.
 
-`allowParallelInProgress` is required: every composition must choose whether several todos may be `in_progress` at once. It is a deployment choice, not a fixed rule: whether concurrent active tasks are legitimate depends on runtime concurrency the tool cannot observe. Use `true` for agents that may fan out work and `false` to enforce the single-active discipline.
+### When to choose it
 
-The flag moves the model-facing instruction and the accepted input together — `true` asks the model to mark every actively worked task and accepts any number, `false` asks for exactly one and rejects a call marking more with `Error: invalid todos: at most one task may be in_progress (got <n>)`. The durable-log invariant does NOT follow it: a log written while parallel work was allowed must still replay after a deployment tightens the policy, so the invariant stays silent on the active count.
+Choose it when one agent session should own the task list and whole-list updates are fine — the common shape for planning tools. Avoid it when several agents must share one list or when you need per-item edits: the list belongs to one agent and every update replaces the whole list. It needs an agent session to exist at all; automation-only surfaces that never run an agent cannot use it.
 
-## Validation
+### Minimal configuration
 
-Beyond the schema's type/required/enum checks, `execute` rejects an empty or duplicate `content`, and any item key beyond `content`/`status` — an extended item shape (ids, nesting) fails loud instead of silently flattening, keeping the logged snapshot equal to what the model believes it wrote. How many tasks may be `in_progress` at once is the deployment's call (§ Configuration): a composition that chooses `true` permits parallel work (concurrent subagents, background commands) to mark several tasks simultaneously. Ordering and the discipline of keeping the list current are left to the model via the tool description.
+`allowParallelInProgress` is required with no default: a composition that omits it fails at load, and a non-boolean value is rejected. Set `true` for agents that may run work concurrently (subagents, background commands, workflow fan-out) and `false` for the single-active discipline.
 
-This package's invariant companion validates every durable `todo/write` payload and requires the event to occur inside an open turn. It validates existing and newly announced sessions once, then advances a committed per-session turn trace for live appends. Core session treats declaration-merged events generically; the producing package owns these todo-specific rules ([event ownership](../../../.agents/notes/implemented/architecture/2026-07-20-todo-event-ownership.md)).
+```yaml
+- name: '@deepseek-ai/dsh-tool-todo'
+  config:
+    allowParallelInProgress: true
+```
 
-## Rendering
+| Field | Default | Meaning |
+|---|---|---|
+| `allowParallelInProgress` | required | Whether several todos may be `in_progress` at once; also selects the active-status clause of the model description |
 
-The canonical result is `{ todos, counts: { pending, inProgress, completed } }`; its Native renderer returns the compact update acknowledgement. The tool also writes the full `todo/write` session event. UIs subscribe to the event stream and render that durable list themselves: the [web client](../../client/ui-conversation) shows a plan strip plus a dedicated tool row off the standing plan — latest `todo/write` with no later `turn/start` ([display](../../../.agents/notes/implemented/feature/2026-07-23-web-todo-display.md), [lifetime](../../../.agents/notes/implemented/feature/2026-07-28-todo-plan-clears-on-next-turn.md)).
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-tool-todo) is the exhaustive source for the accepted field.
 
-## Session projection
+### What each call does
 
-When the composition mounts `ctx.sessionProjections` ([`@deepseek-ai/dsh-session-projection`](../../session/session-projection/README.md)), this package registers the `todos` projection unit under an injected child: `init` = `null` (no write yet), `apply` = take the whole list from each `todo/write` and clear to `null` on each `turn/start` (standing plan; `turn/end` keeps the finished checklist; every other event returns the same state reference), `view` = identity, `stateVersion` = 2. The key merges into `SessionProjectionMap` here (via the Service Definition package's `/types` outlet); the framework drives the unit and carriers serve the value on the history tail page and the `session/projection` push frame. Compositions without the registry are unaffected. Lifetime rationale: [todo plan clears on next turn](../../../.agents/notes/implemented/feature/2026-07-28-todo-plan-clears-on-next-turn.md).
+The agent sends the ENTIRE list on every update; the new list replaces the previous one, so there are no partial updates or per-item edits. Each item is a short task description plus a status of `pending`, `in_progress`, or `completed`. A successful update returns the new counts — `Updated todo list: <pending> pending, <inProgress> in progress, <completed> completed.` — and the UI shows the new plan. Updates fail visibly when a task description is empty or duplicated, when an item carries fields beyond the description and status, or — when parallel work is disabled — when more than one task is marked in progress.
 
-## Export shape
+### Single owner
 
-A function/namespace plugin: it exports `name` / `inject` / `apply` and NO default. Its type-only outlet declares `TodoItem` and the `todo/write` `SessionEventMap` member; the root and `/client` entrypoints both export `TodoItem`. A stray `export default` would collapse the module via the Loader's `unwrapExports` and drop `inject` (see [docs/postmortem/0001](../../../docs/postmortem/0001-acp-default-export-drops-inject.md)).
+The task list belongs to the one agent session that created it — subagents and other agents each keep their own list, and there is no way to share a list between agents. A call from outside an agent session is rejected, so the agent learns the update failed instead of silently writing nowhere. If you need a list shared across agents, this package does not provide it.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the tool and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The tool is built on four commitments:
+
+- **Whole-list replace, log-backed state.** The model resends the entire list; the `todo/write` snapshot lives on the event-sourced session log, so durability, replay, and resume reconstruction come from the log rather than a service.
+- **Single owner.** The list belongs to the calling agent session; there is no shared or swarm scope, and non-agent callers are rejected.
+- **Deployment policy, not a coded rule.** `allowParallelInProgress` is a required composition choice because the tool cannot observe runtime concurrency; the durable-log invariant deliberately stays silent on the active count so a log written under one policy still replays under another.
+- **Validation keeps the logged snapshot honest.** Schema-level rejection of unknown keys and `execute`-level rejection of empty or duplicate content keep the durable snapshot equal to what the model believes it wrote.
+
+The [todo_write tool Agent Note](../../../.agents/notes/implemented/feature/2026-06-29-todo-write-tool.md) records the original design and alternatives; the [parallel in-progress Agent Note](../../../.agents/notes/implemented/feature/2026-07-26-todo-parallel-in-progress.md) records the policy decision.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `Config` schema, tool registration, `todos` projection unit |
+| [`src/types.ts`](src/types.ts) | The one home of the `todos` projection-key declaration and its payload types |
+| [`src/client.ts`](src/client.ts) | Client-namespace re-export of the types outlet |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion: validates durable whole-list snapshots and open-turn ownership |
+
+### Export shape
+
+The plugin is a function/namespace plugin: it exports `name` / `inject` / `apply` and no default export. A stray `export default` would make the Loader's `unwrapExports` collapse the module and drop `inject` (see [postmortem 0001](../../../docs/postmortem/0001-acp-default-export-drops-inject.md)).
+
+### Session projection
+
+When the composition mounts `ctx.sessionProjections` ([`@deepseek-ai/dsh-session-projection`](../../session/session-projection/README.md)), this package registers the `todos` unit on an injected child: the projection is the standing plan — the latest whole `todo/write` list, `null` before the first write, cleared when the next turn starts while `turn/end` keeps the finished checklist visible. The key merges into `SessionProjectionMap` here; carriers serve the value on the history tail page and the `session/projection` push frame. Compositions without the registry are unaffected; see [src/index.ts](src/index.ts) for the unit registration. The lifetime rationale lives in the [todo plan clears on next turn Agent Note](../../../.agents/notes/implemented/feature/2026-07-28-todo-plan-clears-on-next-turn.md).
+
+### Durable-log invariant
+
+The invariant companion registers on `ctx.invariants`, validates existing and newly announced sessions once, and then advances a committed per-session turn trace for live appends. It rejects malformed entries, empty or duplicated content, unknown statuses, and any durable `todo/write` outside an open turn; core session treats declaration-merged events generically, while this producing package owns todo-specific rules. It deliberately says nothing about how many items are `in_progress`, because that is the tool's per-deployment policy, not a durable-data rule ([event ownership](../../../.agents/notes/implemented/architecture/2026-07-20-todo-event-ownership.md)).
+
+### Call mechanics
+
+Each call validates the submitted list against the schema, rejects incoherent input, and on success appends the full snapshot as a `todo/write` session event and returns the new counts; the current list is always the most recent `todo/write` in the log (last-write-wins on replay). See [src/index.ts](src/index.ts) for the exact validation and append steps.

+#### Future: cross-agent and shared lists
+
+The single-owner scope is a deliberate cut, and cross-agent or shared lists remain a separate future design: they would need per-item log deltas and explicit scope selection, and would change the model-visible contract. No design exists yet.

 [English](README.md) | 中文
 
-面向模型的 `todo_write` 工具：agent（智能体）的完整任务列表，每次调用都会整体替换。
+## 概述
 
-## 功能
+`dsh-tool-todo` 为 agent 提供一份可用于规划的结构化任务列表：把多步工作拆成具体任务、标记正在进行的任务、完成后逐项勾掉。列表跨轮次、跨重新打开的会话持续存在，agent 与 UI 始终看到最新计划。一个配置开关决定是否允许多个任务同时处于进行中，适用于并行开展工作的 agent。凡是希望 agent 维护可见任务列表的场景都可以使用它；每次更新整体替换列表，只有拥有该列表的 agent 会话才能修改。
 
-注册一个工具 `todo_write(todos: [{ content, status }])` 到 `ctx.tools`。模型每次调用都会发送完整列表，不存在部分更新或单项编辑。每次调用都会向调用 agent 的会话日志追加 `todo/write` 事件（完整列表快照），具体调用 `agent.session.append('todo/write', { todos })`；当前列表是最新的该类事件（回放时后写覆盖先写）。
+## 目录
 
-`status` 是 `pending`、`in_progress` 或 `completed` 之一。

-## 单一所有者
+-----
 
-该列表属于调用工具的唯一 agent 会话。不存在 subagent／共享／swarm scope：非 agent 调用方（没有 `exec.agent`）无处写入列表，因此会被拒绝。这是有意设置的 scope 限制，详见 Agent Note。
+<a id="use-this-package"></a>
+## 使用本包
 
-## 配置
+当你希望 agent 在工作时维护一份可见的任务列表时使用本包：规划多步工作、展示当前进行中的任务、记录完成情况。挂载它并设置并行开关是唯一的配置步骤；此后每次计划变化，agent 都会通过它自己的规划工具更新列表。
 
-`allowParallelInProgress` 是必填项：每个组合都必须选择是否允许多个 todo 同时处于 `in_progress`。这是部署层的选择而非固定规则：并发的活跃任务是否合理，取决于工具无法观测的运行时并发情况。可能并行展开工作的 agent 使用 `true`，`false` 则强制执行单活跃项纪律。
+### 何时选择
 
-该开关会同时改变面向模型的指令与接受的输入——`true` 要求模型标记每个正在推进的任务并接受任意数量；`false` 要求恰好一个，并以 `Error: invalid todos: at most one task may be in_progress (got <n>)` 拒绝标记更多的调用。持久日志不变式**不**跟随它：在允许并行时写下的日志，在部署收紧策略之后仍必须可回放，因此不变式对活跃数量保持沉默。
+当某个 agent 会话应当拥有任务列表、且整表更新即可满足需求时选择它——这是规划工具的常见形态。当多个 agent 必须共享同一份列表、或需要逐项编辑时，请避开：列表只属于一个 agent，每次更新都会替换整个列表。它要求环境中确实存在 agent 会话；从不运行 agent 的纯自动化表面无法使用它。
 
-## 验证
+### 最小配置
 
-除 schema 的类型／必填／枚举检查外，`execute` 还会拒绝空或重复的 `content`，以及 `content`/`status` 之外的任何条目键——扩展条目形状（id、嵌套）会明确报错而不是被静默压平，保证落日志的快照与模型自认为写入的内容一致。同时可以有多少任务处于 `in_progress` 由部署决定（见 § 配置）：选择 `true` 的组合允许并行工作（并发 subagent、后台命令）同时将多个任务标记为 `in_progress`。列表的顺序及及时更新由模型依照工具描述负责。
+`allowParallelInProgress` 是必填项、没有默认值：省略它的组合会在加载时失败，非布尔值也会被拒绝。可能并发运行工作的 agent（subagent、后台命令、workflow 扇出）设为 `true`，需要单活跃项纪律的设为 `false`。
 
-本包的不变量配套插件会校验每个持久 `todo/write` payload，并要求事件位于开放轮次内。它会各自单次校验现有会话与新发布的会话，随后为实时追加推进逐会话的已提交轮次追踪状态。核心会话只会通用处理声明合并事件，todo 专属规则由生产该事件的包负责（见[事件所有权](../../../.agents/notes/implemented/architecture/2026-07-20-todo-event-ownership.zh.md)）。
+```yaml
+- name: '@deepseek-ai/dsh-tool-todo'
+  config:
+    allowParallelInProgress: true
+```
 
-## 渲染
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `allowParallelInProgress` | 必填 | 是否允许多个 todo 同时处于 `in_progress`；同时选择模型描述中的活跃状态条款 |
 
-规范结果为 `{ todos, counts: { pending, inProgress, completed } }`；其 Native 渲染器返回精简的更新确认。工具还会写入完整 `todo/write` 会话事件。UI 订阅事件流，并自行渲染该持久化列表：[web 客户端](../../client/ui-conversation)基于当前有效计划（其后没有更晚 `turn/start` 的最近一次 `todo/write`）显示计划条和专属工具行（[展示](../../../.agents/notes/implemented/feature/2026-07-23-web-todo-display.zh.md)、[生命周期](../../../.agents/notes/implemented/feature/2026-07-28-todo-plan-clears-on-next-turn.zh.md)）。
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-tool-todo)是每个受支持字段的穷尽式真源。
 
-## 会话投影
+### 每次调用做什么
 
-当组合挂载了 `ctx.sessionProjections`（[`@deepseek-ai/dsh-session-projection`](../../session/session-projection/README.zh.md)）时，本包在一个注入的子插件中注册 `todos` 投影单元：`init` = `null`（尚无写入）、`apply` = 从每个 `todo/write` 取整表，并在每个 `turn/start` 清为 `null`（当前有效计划；`turn/end` 保留刚完成的清单；其余事件都返回同一个状态引用）、`view` = 恒等、`stateVersion` = 2。该键在本包中合并进 `SessionProjectionMap`（经 Service Definition 包的 `/types` 出口）；框架驱动该单元，载体通过历史尾页与 `session/projection` 推送帧提供该值。未挂载注册表的组合不受影响。生命周期理由见 [在下一轮次清空 todo 计划](../../../.agents/notes/implemented/feature/2026-07-28-todo-plan-clears-on-next-turn.zh.md)。
+agent 每次更新都发送完整列表；新列表替换旧列表，因此没有部分更新或逐项编辑。每个条目是一句简短的任务描述，外加 `pending`、`in_progress` 或 `completed` 状态。成功的更新会返回新的计数——`Updated todo list: <pending> pending, <inProgress> in progress, <completed> completed.`——UI 随即展示新计划。任务描述为空或重复、条目带有描述与状态之外的字段、或（禁用并行时）多个任务被标记为进行中，这些情况下更新都会明确失败。
 
-## 导出形状
+### 单一所有者
 
-函数／命名空间插件：导出 `name`/`inject`/`apply`，不提供默认导出。其仅类型出口声明 `TodoItem` 与 `todo/write` `SessionEventMap` 成员；包根入口和 `/client` 入口都导出 `TodoItem`。意外的 `export default` 会被 Loader 的 `unwrapExports` 折叠为默认导出，并导致 `inject` 丢失（参见 [docs/postmortem/0001](../../../docs/postmortem/0001-acp-default-export-drops-inject.zh.md)）。
+任务列表属于创建它的那一个 agent 会话——subagent 与其他 agent 各自维护自己的列表，不存在跨 agent 共享列表的方式。来自 agent 会话之外的调用会被拒绝，因此 agent 会得知更新失败，而不是被静默丢弃。如果你需要多个 agent 共享同一份列表，本包不提供该能力。

+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释工具背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+本工具建立在四项承诺之上：
+
+- **整表替换、日志承载状态。** 模型重新发送整个列表；`todo/write` 快照存放在事件溯源的会话日志上，持久性、回放与恢复重建都来自日志而非服务。
+- **单一所有者。** 列表属于调用 agent 会话；不存在共享或 swarm 作用域，非 agent 调用方会被拒绝。
+- **部署策略，而非编码规则。** `allowParallelInProgress` 是必填组合选择，因为工具无法观测运行时并发；持久日志不变式刻意不跟随它，因此一种策略下写入的日志在部署收紧另一种策略后仍可回放。
+- **校验让落库快照保持诚实。** schema 层拒绝未知键、`execute` 层拒绝空或重复 content，使持久快照与模型自认为写入的内容一致。

+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：`Config` schema、工具注册、`todos` 投影单元 |
+| [`src/types.ts`](src/types.ts) | `todos` 投影键声明及其载荷类型的唯一归属地 |

+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件：校验持久整表快照与开放轮次归属 |
+
+### 导出形状
+
+本插件是函数／命名空间插件：导出 `name` / `inject` / `apply`，没有默认导出。多余的 `export default` 会让 Loader 的 `unwrapExports` 折叠模块并丢弃 `inject`（参见 [postmortem 0001](../../../docs/postmortem/0001-acp-default-export-drops-inject.zh.md)）。
+
+### 会话投影
+
+当组合挂载 `ctx.sessionProjections`（[`@deepseek-ai/dsh-session-projection`](../../session/session-projection/README.zh.md)）时，本包在注入的子插件中注册 `todos` 单元：投影即有效计划——最新的整份 `todo/write` 列表，首次写入前为 `null`，下一轮次开始时清空，而 `turn/end` 保留刚完成的清单。该键在此处合并进 `SessionProjectionMap`；载体通过历史尾页与 `session/projection` 推送帧提供该值。未挂载注册表的组合不受影响；单元注册见 [src/index.ts](src/index.ts)。生命周期理由见 [todo 计划在下一轮次清空 Agent Note](../../../.agents/notes/implemented/feature/2026-07-28-todo-plan-clears-on-next-turn.zh.md)。
+
+### 持久日志不变式
+
+不变式伴生插件注册到 `ctx.invariants`，先分别校验既有会话与新公布会话一次，再为实时追加推进按会话提交的轮次轨迹。它会拒绝畸形条目、空或重复 content、未知状态，以及开放轮次之外的持久 `todo/write`；核心 session 通用处理声明合并事件，而本生产包拥有 todo 专用规则。它刻意不约束有多少条目处于 `in_progress`，因为那是工具按部署制定的策略，而非持久数据规则（见[事件归属](../../../.agents/notes/implemented/architecture/2026-07-20-todo-event-ownership.zh.md)）。
+
+### 调用机制
+
+每次调用都会先校验提交的列表是否符合 schema，拒绝不一致的输入，成功后把完整快照作为 `todo/write` 会话事件追加并返回新的计数；当前列表始终是日志中最近一次 `todo/write`（回放时后写覆盖先写）。确切的校验与追加步骤见 [src/index.ts](src/index.ts)。

-Typert separates source analysis, runtime storage, and Loader discovery.
+## Summary
 
-| Package | Role | Cordis key |
+With the typert group, Client environments can call Host capabilities as typed methods and share generated schemas and reflection without hand-written wire code. A build-time generator turns source type declarations into compiler-independent models and runtime artifacts, a runtime registry stores those artifacts, and a Loader integration registers them automatically in Loader compositions. A shared protocol package supplies the Remote-call declarations — decorators, wire descriptors, codecs, and provider contracts — that business packages, generated artifacts, the Host Gateway, and the Client API all consume. This page maps the four packages; each package README owns its configuration, usage, and limits.

+## 概述
 
-| 包 | 职责 | Cordis 键 |
+借助 typert 组，Client 环境能以类型化方法调用 Host 能力，并在无需手写协议代码的情况下共享生成的 schema 与反射信息。构建时生成器把源代码类型声明转换为与编译器无关的模型与运行时产物，运行时注册表保存这些产物，Loader 集成则在 Loader 组合中自动注册它们。共享的协议包提供 Remote 调用声明——装饰器、wire 描述符、编解码器与提供方约定——供业务包、生成产物、Host Gateway 与 Client API 共同消费。本页是四个包的索引；每个包的 README 负责各自的配置、用法与限制。

-TypeScript project analyzer and model-driven Typert generator. It converts the developer-authored source type tree into compiler-independent `FaceModel` and `TypeGraph` data before any artifact is rendered. Static analysis can consume that model without Cordis; emitters never receive TypeScript AST or checker objects.
+## Summary
 
-The analyzer can use independent `ts.Program` instances seeded from `tsconfig.host.json` or `tsconfig.client.json`. Direct project references establish compiler-face membership, while package subpaths establish Typert runtime-face contributions: an ordinary single-project package declaring `dsh.client` may contribute both Host and Client runtime models, and only a split project explicitly referenced through `tsconfig.host.json` or `tsconfig.client.json` is restricted to that corresponding face. `package.json#exports` establishes every cross-package public boundary, and source imports or re-exports are the only allowed cross-face edges. Types owned by NPM dependencies, including global declarations from `@types` packages, remain `external` references instead of being expanded.
+`dsh-typert-generator` turns source TypeScript into compiler-independent data and runnable artifacts at build time: it analyzes a workspace's package type trees, produces a `FaceModel` and type graph, and emits executable JavaScript with supported Zod schemas and a `TYPERT` reflection contribution, plus matching declarations. It is a build-time library, not a plugin — it never runs inside a live agent session. The repository's Host tsdown runs it automatically; a business package opts in by exporting `./typert` and `./client/typert` entries, and the generator validates those exports and published file lists. Static consumers can also call the analyzer directly for type inspection or catalog generation without publishing anything.
 
-## Analysis Model
+## Table of Contents
 
-Each face contains package exports, Cordis services and events, explicitly tagged objects and schemas, and a type graph for their reachable declarations. The graph preserves declaration identity, generic parameters and applications, explicit inheritance, conditional and mapped types, import attributes, abstract modifiers, and source JSDoc. Service and `@typert object` APIs expose public instance members only; constructors, static members, and non-public members are excluded.

-`WorkspaceAnalyzer` defaults to `check` mode and fails on TypeScript syntax or semantic diagnostics, missing reachable public annotations, private cross-package references, and reachable declaration merges that the model cannot retain losslessly. `write` mode inserts checker-derived annotations, rebuilds the program, and returns a clean check-mode model.
+-----
 
-## Emission and Opt-in Publication
+<a id="use-this-package"></a>
+## Use this package
 
-`FaceModelEmitter` consumes only the model. It emits executable JavaScript containing supported Zod schemas and a `TYPERT` contribution, plus a declaration file whose schemas are typed as `z.ZodType<SourceType>` through the package's public export. Unsupported Zod projections fail instead of flattening or weakening the source type.
+This package is for package and repository maintainers who wire Typert generation into a build or consume generated artifacts. Publication is opt-in: declare the export entries, run the build, and the artifacts appear in `lib/`; static analysis needs no artifact.
 
-`WorkspaceTypertGenerator` discovers contributors by walking package public exports reachable from Cordis `Context` or `Events` augmentations and explicit `@typert` declarations. When invoked for artifact publication, it requires host artifacts at `lib/typert.host.{js,d.ts}` exposed as `package/typert`, and client artifacts at `lib/typert.client.{js,d.ts}` exposed as `package/client/typert`. Generated declarations expose `TYPERT` as `unknown`, so contributing business packages do not depend on the runtime registry.
+### Publishing Typert artifacts from a package
 
-Publication is package opt-in, and business packages without the corresponding public entry do not need Typert artifacts. The repository's Host tsdown runs workspace Typert generation with `tsconfig.host.json` as its only program seed; it produces both Host reflection artifacts and the `typert.remote-client.*` projection of Host Remote contracts for the Client. The subsequent Client tsdown neither starts Typert nor analyzes `tsconfig.client.json`. Static consumers can still call `WorkspaceAnalyzer` directly, explicitly select a face and package subset, and process packages in batches without publishing or loading runtime artifacts.
+A contributing package declares the host-face artifact export in `package.json`; packages that contribute both faces also declare `./client/typert`, and packages with Remote methods declare `./remote`:
 
-## Repository-specific Cordis projection
+```yaml
+exports:
+  "./typert":
+    types: "./lib/typert.host.d.ts"
+    default: "./lib/typert.host.js"
+files:
+  - "lib/typert.host.js"
+  - "lib/typert.host.d.ts"
+```
 
-The root package export includes the model-driven extraction, completeness checks, and deterministic text renderers used by this repository's Cordis catalogs. They accept a `CordisCatalogPolicy`; repository-owned type links, foundation/exemption classifications, and inherited Cordis entries remain in `scripts/gen-cordis-catalog.ts` and are passed in explicitly. The generator package therefore contains projection mechanics, not a hidden copy of this repository's documentation taxonomy.
+After the build, `lib/typert.host.js` and `lib/typert.host.d.ts` exist and the [loader](../loader/README.md) registers the contribution in Loader compositions. The generated declaration file exposes `TYPERT` as `unknown`, so contributing packages never depend on the runtime registry. The generator fails the build when a declaration is missing, points at the wrong file, or publishes Remote artifacts without Remote methods; unsupported Zod projections fail with a `TypertEmitError` naming the construct instead of flattening or weakening the source type.
 
+### Analyzing a workspace statically
+
+Static consumers call `WorkspaceAnalyzer` directly against the workspace's `tsconfig.host.json` and `tsconfig.client.json` aggregates, select a face and package subset, and read the resulting `FaceModel` and type graph without emitting or loading runtime artifacts. `analyzeInBatches()` processes a large package selection through bounded compiler programs with the same model shape, and `discoverPackages()` finds contributing packages without building a type-checker program.
+
+### Running generation inside a tsdown build
+
+The package's `./tsdown` subpath provides `typertPlugin()` for the root tsdown config: it lowers standard decorators in TypeScript dependencies before bundling and emits the model-driven face artifacts at the package output root. In `package` mode it emits only the bundled package; in `workspace` mode it emits every explicit contributor once.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the generator reaches a compiler-independent model and what it emits; the observable build behavior is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The generator is built on one separation: extraction and emission are decoupled through the compiler-independent model. `WorkspaceAnalyzer` reads TypeScript programs seeded from the face aggregate tsconfigs and produces `FaceModel` and `TypeGraph` data; `FaceModelEmitter` consumes only that model and never receives compiler nodes. The model retains declaration identity, generic parameters and applications, explicit inheritance, conditional and mapped types, import attributes, abstract modifiers, and source JSDoc, and excludes constructors, static members, and non-public members.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Public API: analyzer, emitter, workspace generator, renderer, catalog projection |
+| [`src/analyzer.ts`](src/analyzer.ts) | `WorkspaceAnalyzer`: face programs, check/write modes, batching, discovery, source index |
+| [`src/model.ts`](src/model.ts) | Compiler-independent model types |
+| [`src/emitter.ts`](src/emitter.ts) | `FaceModelEmitter`: Zod schema and declaration emission, Remote declarations |
+| [`src/workspace.ts`](src/workspace.ts) | `WorkspaceTypertGenerator`: discovery, generation, export and files validation |
+| [`src/tsdown-plugin.ts`](src/tsdown-plugin.ts) | tsdown plugin face: decorator lowering and artifact emission |
+| [`src/cordis-catalog.ts`](src/cordis-catalog.ts) | Catalog projection used by the generated Cordis catalogs |
+
+### Analysis and faces
+
+Host and client are independent TypeScript programs. Direct project references establish compiler-face membership, while `dsh.client` package subpaths establish runtime-face contribution; `package.json#exports` marks every cross-package public boundary, and imports or re-exports are the only cross-face edges. `check` mode fails on syntax or semantic diagnostics, missing public annotations, private cross-package references, and reachable declaration merges the model cannot retain losslessly; `write` mode inserts checker-derived annotations and returns a clean check-mode model. Types owned by NPM dependencies remain `external` references instead of being expanded.
+
+### Emission and publication contract
+
+`FaceModelEmitter` emits executable JavaScript containing supported Zod schemas and the `TYPERT` contribution, plus a declaration file whose schemas are typed `z.ZodType<SourceType>` through the package's public export; unsupported Zod projections fail. The Host face with Remote methods additionally emits `typert.remote-client.*` projections of Host Remote contracts for the Client. `WorkspaceTypertGenerator` validates each contributor's `package.json`: `./typert` and `./client/typert` (and `./remote` when Remote methods exist) must point at the exact generated files, and the `files` list must include them.
+
+### Catalog projection
+
+The root export includes the model-driven extraction, completeness checks, and deterministic text renderers used by this repository's Cordis catalogs. They accept a `CordisCatalogPolicy`; repository-owned type links, foundation and exemption classifications, and inherited Cordis entries stay in `scripts/gen-cordis-catalog.ts` and are passed in explicitly, so this package contains projection mechanics, not a hidden copy of the repository's documentation taxonomy.

 ## Model Experience
 
-None, as this package runs at build or test time and never contributes to a model request.
+None, as the build-time generator runs outside any agent runtime and touches no model request.
 
 #### KV Cache effect
 
-None.
+No direct effect; generated artifacts reach a request only when a consumer places them in one.
 
 ## Known Limitations and Deferred Work
 
-- Package export patterns are skipped; contributing packages need concrete export targets.
-- Cross-face named and star re-exports produce links; namespace re-exports fail until `TypeTargetModel` can represent a module namespace without flattening it.
-- The Zod emitter supports a deliberate subset of the modeled TypeScript graph. Generic schema declarations and computed constructs such as conditional or mapped schema roots fail until a concrete schema-factory policy exists.
-- Cross-face links are represented for analysis, but no generated schema currently requires a runtime cross-face Zod import.
-- Discovery follows source files reachable from concrete public exports; declarations that are neither exported nor imported by that graph are intentionally outside the package model.
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define what the generator cannot model or emit; they are current package constraints, not a task backlog.
+
+- **Package export patterns are skipped** — contributing packages need concrete export targets; wildcard export patterns are not analyzed.

-TypeScript 项目分析器和模型驱动的 Typert 生成器。在生成任何产物之前，它会先将开发者编写的源类型树转换为独立于编译器的 `FaceModel` 和 `TypeGraph` 数据。静态分析无需 Cordis 即可消费该模型；各产物生成组件均不会接收 TypeScript 抽象语法树（AST）或类型检查器对象。
+## 概述
 
-分析器可以分别使用由 `tsconfig.host.json` 或 `tsconfig.client.json` 初始化的独立 `ts.Program`。直接项目引用确定编译器 face 的成员归属，而包子路径确定 Typert 运行时 face 的贡献：声明 `dsh.client` 的普通单项目包可以同时贡献 Host 与 Client 运行时模型；只有通过 `tsconfig.host.json` 或 `tsconfig.client.json` 显式引用的拆分项目，才会被限制在相应 face。`package.json#exports` 确定所有跨包公开边界，跨 face 的边只能来自源码导入或重新导出。NPM 依赖拥有的类型（包括 `@types` 包中的全局声明）继续以 `external` 引用表示，不会被展开。
+`dsh-typert-generator` 在构建时把源代码 TypeScript 转换为与编译器无关的数据与可运行产物：它分析工作区各包的类型树，生成 `FaceModel` 与类型图，并输出包含受支持 Zod schema 与 `TYPERT` 反射贡献的可执行 JavaScript，以及配套声明文件。它是构建时库而非插件——绝不会在实时 agent 会话中运行。仓库的 Host tsdown 会自动运行它；业务包通过导出 `./typert` 与 `./client/typert` 入口选择加入，生成器会校验这些导出与发布文件清单。静态消费方也可以直接调用分析器进行类型检查或目录生成，无需发布任何内容。
 
-## 分析模型
+## 目录
 
-每个 face 包含包导出、Cordis 服务与事件、显式标记的对象与 schema，以及涵盖其可达声明的类型图。类型图保留声明标识、泛型参数及应用、显式继承、条件类型与映射类型、导入属性、abstract 修饰符和源码 JSDoc。服务和 `@typert object` 对外接口仅暴露公共实例成员；构造函数、静态成员与非公共成员均被排除。

-`WorkspaceAnalyzer` 默认采用 `check` 模式，遇到 TypeScript 语法或语义诊断、可达公开声明缺少类型标注、跨包私有引用，以及模型无法无损保留的可达声明合并时，分析会失败。`write` 模式会插入类型检查器推导出的类型标注，重建该程序，并返回无诊断的检查模式模型。
+-----
 
-## 产物生成与选择性发布
+<a id="use-this-package"></a>
+## 使用本包
 
-`FaceModelEmitter` 只消费模型。它会生成可执行 JavaScript，其中包含受支持的 Zod schema 和一个 `TYPERT` contribution；同时生成声明文件，通过包的公开导出将其中的 schema 标注为 `z.ZodType<SourceType>`。遇到不支持的 Zod 投影时，生成会失败，不会展平或弱化源类型。
+本包供把 Typert 生成接入构建或消费生成产物的包维护者与仓库维护者使用。发布是选择加入的：声明导出入口、运行构建，产物即出现在 `lib/` 中；静态分析则不需要产物。
 
-`WorkspaceTypertGenerator` 会遍历从 Cordis `Context` 或 `Events` 扩充声明及显式 `@typert` 声明可达的包公开导出，以发现贡献方。发布产物时，它要求宿主侧产物位于 `lib/typert.host.{js,d.ts}` 并以 `package/typert` 暴露，客户端侧产物位于 `lib/typert.client.{js,d.ts}` 并以 `package/client/typert` 暴露。生成的声明将 `TYPERT` 暴露为 `unknown`，因此参与贡献的业务包无需依赖运行时注册表。
+### 从包中发布 Typert 产物
 
-各包可自行选择是否发布，未提供对应公开入口的业务包无需生成 Typert 产物。仓库的 Host tsdown 会以 `tsconfig.host.json` 为唯一 program 种子运行 workspace Typert 生成；它既生成 Host 反射产物，也把 Host Remote 约定投影为 Client 使用的 `typert.remote-client.*`。后续 Client tsdown 不启动 Typert，也不分析 `tsconfig.client.json`。静态消费方仍可直接调用 `WorkspaceAnalyzer`，显式选择 face 与包子集，并在不发布或加载运行时产物的情况下分批处理包。
+参与贡献的包在 `package.json` 中声明宿主侧产物导出；同时贡献两侧的包还要声明 `./client/typert`，含 Remote 方法的包还要声明 `./remote`：
 
-## 本仓库的 Cordis 投影
+```yaml
+exports:
+  "./typert":
+    types: "./lib/typert.host.d.ts"
+    default: "./lib/typert.host.js"
+files:
+  - "lib/typert.host.js"
+  - "lib/typert.host.d.ts"
+```
 
-包根导出中包含本仓库 Cordis 目录使用的模型驱动提取逻辑、完整性检查和确定性文本渲染器。它们接受 `CordisCatalogPolicy`；由仓库持有的类型链接、基础类型／豁免类型分类和继承的 Cordis 条目仍位于 `scripts/gen-cordis-catalog.ts`，并由调用方显式传入。因此，生成器包只包含投影机制，不会隐式复制本仓库的文档分类体系。
+构建完成后，`lib/typert.host.js` 与 `lib/typert.host.d.ts` 即存在，[loader](../loader/README.zh.md) 会在 Loader 组合中注册该贡献。生成的声明文件把 `TYPERT` 暴露为 `unknown`，因此参与贡献的包永远不会依赖运行时注册表。当声明缺失、指向错误文件，或在没有 Remote 方法的情况下发布 Remote 产物时，生成器会使构建失败；不支持的 Zod 投影会以 `TypertEmitError` 指明具体构造并失败，而不会展平或弱化源类型。
 
+### 静态分析工作区
+
+静态消费方直接以工作区的 `tsconfig.host.json` 与 `tsconfig.client.json` aggregate 调用 `WorkspaceAnalyzer`，选择 face 与包子集，并在不生成或加载运行时产物的前提下读取生成的 `FaceModel` 与类型图。`analyzeInBatches()` 通过有界的编译器程序处理大批量包选择，模型形态保持一致；`discoverPackages()` 无需构建类型检查程序即可找出参与贡献的包。
+
+### 在 tsdown 构建中运行生成
+
+包的 `./tsdown` 子路径为根 tsdown 配置提供 `typertPlugin()`：它在打包前降低 TypeScript 依赖中的标准装饰器，并在包输出根目录生成模型驱动的 face 产物。`package` 模式只生成当前打包的包；`workspace` 模式对每个显式贡献方各生成一次。

+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释生成器如何得到与编译器无关的模型以及它生成什么；可观察的构建行为已在[使用本包](#use-this-package)中说明。
+
+### 设计理念
+
+生成器建立在一个分离之上：提取与生成通过与编译器无关的模型解耦。`WorkspaceAnalyzer` 读取以 face aggregate tsconfig 为种子的 TypeScript 程序，产出 `FaceModel` 与 `TypeGraph` 数据；`FaceModelEmitter` 只消费该模型，绝不接收编译器节点。模型保留声明标识、泛型参数及应用、显式继承、条件类型与映射类型、导入属性、abstract 修饰符与源码 JSDoc，并排除构造函数、静态成员与非公共成员。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 公共 API：分析器、生成器、工作区生成器、渲染器、目录投影 |
+| [`src/analyzer.ts`](src/analyzer.ts) | `WorkspaceAnalyzer`：face 程序、check/write 模式、分批、发现、源码索引 |
+| [`src/model.ts`](src/model.ts) | 与编译器无关的模型类型 |
+| [`src/emitter.ts`](src/emitter.ts) | `FaceModelEmitter`：Zod schema 与声明生成、Remote 声明 |
+| [`src/workspace.ts`](src/workspace.ts) | `WorkspaceTypertGenerator`：发现、生成、导出与文件清单校验 |
+| [`src/tsdown-plugin.ts`](src/tsdown-plugin.ts) | tsdown 插件面：装饰器降低与产物生成 |
+| [`src/cordis-catalog.ts`](src/cordis-catalog.ts) | 生成 Cordis 目录所用的目录投影 |
+
+### 分析与 face
+
+Host 与 Client 是两个独立的 TypeScript 程序。直接项目引用确定编译器 face 的成员归属，`dsh.client` 包子路径则确定运行时 face 的贡献；`package.json#exports` 划定所有跨包公开边界，跨 face 的边只能来自导入或重新导出。`check` 模式遇到语法或语义诊断、缺失的公开类型标注、跨包私有引用，以及模型无法无损保留的可达声明合并时都会失败；`write` 模式插入类型检查器推导出的标注，并返回无诊断的 check 模式模型。NPM 依赖拥有的类型继续以 `external` 引用表示，不会被展开。
+
+### 生成与发布约定
+
+`FaceModelEmitter` 输出包含受支持 Zod schema 与 `TYPERT` 贡献的可执行 JavaScript，以及把 schema 通过包的公开导出标注为 `z.ZodType<SourceType>` 的声明文件；不支持的 Zod 投影会失败。含 Remote 方法的 Host face 还会额外为 Client 生成 Host Remote 约定的 `typert.remote-client.*` 投影。`WorkspaceTypertGenerator` 校验每个贡献方的 `package.json`：`./typert` 与 `./client/typert`（存在 Remote 方法时还有 `./remote`）必须指向精确的生成文件，且 `files` 清单必须包含它们。
+
+### 目录投影
+
+根导出包含本仓库 Cordis 目录使用的模型驱动提取逻辑、完整性检查与确定性文本渲染器。它们接受 `CordisCatalogPolicy`；由仓库持有的类型链接、基础类型／豁免分类与继承的 Cordis 条目仍位于 `scripts/gen-cordis-catalog.ts`，由调用方显式传入，因此本包只包含投影机制，不会隐式复制仓库的文档分类体系。

It then follows Cordis `internal/plugin` lifecycle notifications, resolves each entry package's `package.json`, imports `./typert` when exported, validates its `TYPERT` manifest, and registers the contribution until the entry or this plugin unmounts. An import that settles after either owner is gone is discarded.
+With `dsh-typert-loader` mounted, every package that mounts in a Loader composition automatically contributes its generated Typert reflection and schemas to the runtime registry — and withdraws them when the package or the plugin unmounts. Packages without the generated export are skipped, so adding the plugin to any composition is safe. An explicit `packages` list covers plugins nested behind another Loader entry, whose fibers carry no resolvable package specifier. It is a Node-only plugin and needs the config-tree resolution anchor to resolve packages.
 
-`packages` lists additional package artifacts to register for plugins nested behind another Loader entry. Cordis fibers do not retain those nested plugins' npm specifiers, so this boundary is explicit; every configured package must resolve from the config tree and export `./typert`.
+## Table of Contents
 
-Packages without the export are skipped. Package resolution and imported manifests are cached for the process lifetime, so adding an export requires a restart. A malformed artifact fails activation when already mounted; a later failure is logged without preventing unrelated packages from registering.

+## Use this package
+
+Mount this plugin in a Host Loader composition that loads packages publishing generated Typert artifacts. The registry itself comes from `dsh-typert-registry`; this plugin only discovers and registers.
+
+### Minimal configuration
+
+Load the registry and the loader; the loader defaults to discovering every Loader entry:
+
+```yaml
+- name: '@deepseek-ai/dsh-typert-registry'
+- name: '@deepseek-ai/dsh-typert-loader'
+```
+
+| Field | Default | Meaning |
+|---|---|---|
+| `packages` | `[]` | Additional package artifacts to register for plugins nested behind another Loader entry; each must resolve from the config tree and export `./typert` |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-typert-loader) is the exhaustive source for every accepted field.
+
+### What gets registered
+
+Each qualifying Loader entry contributes its generated host-face reflection and schemas to the runtime registry. Registration follows the entry lifecycle: it is withdrawn when the entry or the plugin unmounts, and a registration whose import settles after both are gone is discarded.
+
+### Observable behavior and failures
+
+Packages without the export are skipped silently. Resolution verdicts and imported manifests are cached for the process lifetime, so adding a `./typert` export requires a restart. A malformed artifact among already-mounted entries fails activation loudly; a later failure is logged per package without preventing unrelated packages from registering. An explicit `packages` entry that cannot be resolved from the config tree, or that lacks the export, fails loudly and names the package.

+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the loader scans, validates, and registers; the observable behavior is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The plugin is an incremental scanner mirroring the client-modules node half: every Cordis `internal/plugin` emission marks the fiber's entry name dirty, and a microtask flush reconciles each dirty name against the live Loader entries; the activation pass seeds the same dirty set with all current entries.
+
+### Manifest validation
+
+`validateTypertManifest()` is the module/file boundary: the manifest crosses from a build artifact into the typed registry, so every field is checked. The manifest must name the package that exports it, carry face `host`, hold zod v4 schema instances, and keep well-formed service, event, object, member, type, and documentation records; invocation descriptors must use strict codecs. Every failure names the package and the defect.
+
+### Caching and ownership
+
+Verdicts (resolvable specifier, export presence) and imported manifests are cached per package name and never expire. Registrations are keyed by entry name and withdrawn through the exact `ctx.typert.register()` disposer; in-flight tasks are tracked per entry so a late import cannot register a contribution after its owner is gone.

 [English](README.md) | 中文
 
-生成的 Typert 产物所用的 Loader 集成，仅支持 Node。该插件需要 `ctx.loader` 和 `ctx.typert`；它本身不提供注册表。
+## 概述
 
-激活时，该插件会扫描现有的 Loader 配置项。随后它会监听 Cordis `internal/plugin` 生命周期通知，解析每个配置项所属包的 `package.json`，在其导出 `./typert` 时导入该子路径，校验其 `TYPERT` manifest（元数据清单），并注册该贡献项，直到配置项或本插件卸载。如果导入操作在配置项或本插件卸载后才结束，系统会丢弃其结果。
+挂载 `dsh-typert-loader` 后，Loader 组合中每个挂载的包都会自动把其生成的 Typert 反射与 schema 贡献给运行时注册表——并在包或本插件卸载时自动撤销。没有该导出的包会被跳过，因此在任何 Loader 组合中挂载它都是安全的。显式 `packages` 用于覆盖嵌套在另一 Loader 配置项之下的插件，这些插件的 fiber 不携带可解析的包说明符。它是仅支持 Node 的插件，需要配置树解析锚点才能解析包。
 
-`packages` 用于列出需要为嵌套在另一 Loader 配置项下的插件额外注册的包产物。Cordis fiber 不会保留这些嵌套插件的 npm 包说明符，因此这里通过显式配置划定边界；配置中列出的每个包都必须能从配置树解析，并导出 `./typert`。
+## 目录
 
-未导出该子路径的包会被跳过。包解析结果和已导入的 manifest 会在整个进程生命周期内缓存，因此新增该导出后必须重启进程。插件激活时，如果已挂载 Loader 配置项对应的产物格式错误，激活会失败；之后才发生的失败只会记录到日志，不会阻止无关包完成注册。

+## 使用本包
+
+在加载发布生成 Typert 产物的包的 Host Loader 组合中挂载本插件。注册表本身来自 `dsh-typert-registry`；本插件只负责发现与注册。
+
+### 最小配置
+
+加载注册表与 loader；loader 默认发现每一个 Loader 配置项：
+
+```yaml
+- name: '@deepseek-ai/dsh-typert-registry'
+- name: '@deepseek-ai/dsh-typert-loader'
+```
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `packages` | `[]` | 为嵌套在另一 Loader 配置项下的插件额外注册的包产物；每个包都必须能从配置树解析，并导出 `./typert` |
+
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-typert-loader)是每个受支持字段的穷尽式真源。
+
+### 注册什么
+
+每个符合条件的 Loader 配置项都会把其生成的宿主侧反射与 schema 贡献给运行时注册表。注册跟随配置项生命周期：配置项或本插件卸载时撤销；在两者都已消失后才结束的注册会被丢弃。
+
+### 可观察行为与失败
+
+没有该导出的包会被静默跳过。解析结论与已导入的 manifest 会在整个进程生命周期内缓存，因此新增 `./typert` 导出后必须重启。已挂载配置项对应的产物格式错误时，激活会大声失败；之后才发生的失败按包记录日志，不会阻止无关包完成注册。无法从配置树解析、或缺少该导出的显式 `packages` 条目会大声失败并指名该包。

+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释 loader 如何扫描、校验与注册；可观察行为已在[使用本包](#use-this-package)中说明。
+
+### 设计理念
+
+本插件是一个增量扫描器，与 client-modules 的 Node 半实现对称：每次 Cordis `internal/plugin` 事件都会把该 fiber 的配置项名称标记为脏，微任务 flush 会针对实时 Loader 配置项逐一调和每个脏名称；激活阶段用所有当前配置项填充同一脏集合。
+
+### Manifest 校验
+
+`validateTypertManifest()` 是模块／文件边界：manifest 从构建产物进入类型化注册表，因此每个字段都会被检查。manifest 必须指名导出它的包、携带 `host` face、持有 zod v4 schema 实例，并保持服务、事件、对象、成员、类型与文档记录格式正确；调用描述符必须使用严格编解码器。每次失败都会指名包与缺陷。
+
+### 缓存与归属
+
+结论（可解析说明符、是否导出）与已导入的 manifest 按包名缓存且永不过期。注册按配置项名称键控，并通过 `ctx.typert.register()` 返回的同一资源释放函数撤销；进行中的任务按配置项跟踪，因此迟到的导入不可能在其所有者消失后注册贡献。

 # @deepseek-ai/dsh-typert-protocol
 
 English | [中文](README.zh.md)
 
-Compiler-independent declarations shared by business packages, generated Typert artifacts, the Host Gateway, and Client API. This package owns the Remote Service base, decorators, explicit binding fallback, merge-extensible protocol maps, invocation descriptors, codecs, and provider contracts; it does not run TypeScript analysis or register a concrete Cordis service.
+## Summary
 
-## Remote declarations
+With `dsh-typert-protocol`, business packages can expose Host methods to Remote clients: mark a method with `@Remote` (or `@RemoteScope` for scoped receivers), bind the service to a wire namespace, and associate Host objects and scoped Contexts with wire identities through the merge-extensible protocol maps. Generated artifacts, the Host Gateway, and the Client API consume the same invocation descriptors, codecs, and provider contracts, so one declaration set stays in sync across every face. The package registers no Cordis service and runs no TypeScript analysis; it declares types and decorator markers only.
 
-- `@Remote` marks a public instance method for direct invocation on its registered Cordis Service.
-- `@RemoteScope(key)` marks a method whose receiver is selected from a merge-declared scoped Context kind.
-- `TypertRemoteService` binds the Cordis key passed to `super(ctx, serviceKey, options?)` to the same default wire namespace.
-- `bindTypertRemote(this, serviceKey, options?)` provides the same visible, frozen binding for a Service that cannot inherit from `TypertRemoteService`.
-- `remoteMethods(service)` returns a detached declaration-order snapshot used by the Gateway's SRC fallback.
+## Table of Contents
 
-A Host method opts into cooperative cancellation by declaring `signal: AbortSignal` as its final parameter. `InvocationDescriptor.cancellation` records that reserved injection point; the signal never becomes a JSON parameter or lookup field. SRC recognizes the final parameter name, while strict generation also verifies the global `AbortSignal` type.

+- [Further Exploration](#further-exploration)
+- [Model Experience](#model-experience)
+- [Known Limitations and Deferred Work](#known-limitations-and-deferred-work)
+- [Dev Note](#dev-note)
 
-Decorator initializers retain markers in a module-private `WeakMap` keyed by the Service prototype. They do not add constructor symbols, prototype properties, parameter metadata, or runtime reflection fields. A `TypertRemoteService` exposes the same public readonly `typertRemote` binding that the explicit helper returns.
+-----
 
-## Typert protocol
+<a id="use-this-package"></a>
+## Use this package
 
-Business packages extend `TypertLookupMap` and `TypertContextMap` to associate Host objects or scoped Contexts with their wire identities. Generated artifacts extend `TypertRemoteMap`, `TypertRemoteScopeMap`, and `TypertRemoteNamespaceMap` so Client imports expose only selected Remote methods. `InvocationDescriptor` is the shared runtime form consumed by the registry, Gateway, and Client Remote.
+This package is for business-package and assembly maintainers who expose Host capabilities to Remote clients. It is a declarations library: mark methods, bind services, and let the generated pipeline and the Gateway do the rest.
 
-The Host assembly extends `TypertRemoteEventSelection` with the Cordis events it forwards to consumers, which narrows the `ctx.remote.$on` key face. `TypertForwardableEvent` accepts unscoped `void` notifications and scoped async waterfalls whose final `next()` callback returns the event's result type. `TypertClientEventListener` derives the Client listener from that same `Events` member: Host subject types declared under matching `TypertLookupMap` and `TypertContextMap` keys become Client `Context`, while `AbortSignal`, optional and readonly object fields, arrays, callbacks, and result types are preserved. `TypertClientRemote` exposes only `$mount()` and `$on()`; event transport is private to Gateway.
+### Exposing a Host method
 
-Lookup and Context packages own both sides of their contract: declaration merging supplies the static association, while runtime providers register identity resolution with `ctx.typert`. Host and Client Context adapters both map `Context -> wire identity` and `wire identity -> Context`; the Host adapter additionally supplies the stable wire declaration, and Host composition may override its synchronous or asynchronous resolver. Policy rejections may use `TypertLookupFailure` to carry a failure value owned by the boundary adapter. Strict codecs carry generated schemas; `src-json` codecs identify the weaker source-launch path.
+A business package marks a public instance method with `@Remote` (or `@RemoteScope(key)` when the receiver comes from a scoped Context), and the owning service either extends `TypertRemoteService` or declares a `typertRemote` binding through `bindTypertRemote()`:
 
+```text
+import { Remote, TypertRemoteService } from '@deepseek-ai/dsh-typert-protocol'
+
+export class GoalService extends TypertRemoteService {
+  @Remote
+  async create(agentId: string, objective: string): Promise<GoalResult> {
+    ...
+  }
+}
+```
+
+Generation turns the method into a wire endpoint under the service's namespace; Clients call it as a typed method through `ctx.remote` (see the [API Gateway reference](../../../docs/api-gateway.md)). A method opts into cooperative cancellation by declaring `signal: AbortSignal` as its final parameter — the signal is injected, never a JSON parameter or lookup field.
+
+### Associating Host objects and Contexts with wire identities
+
+Complex Host objects cannot cross the wire directly. A business package declares the association through the merge-extensible `TypertLookupMap` and `TypertContextMap`. Host and Client Context adapters both map `Context` to a wire identity and that identity back to `Context`; the Host adapter also owns the stable wire declaration. Host composition may override its synchronous or asynchronous resolver. A policy rejection can throw `TypertLookupFailure` to carry an adapter-owned failure value to the caller.
+
+### Receiving forwarded Host events on the Client
+
+The Host assembly extends `TypertRemoteEventSelection` with the Cordis events it forwards to consumers, which narrows the `ctx.remote.$on` key set. `TypertForwardableEvent` accepts unscoped `void` notifications and scoped async waterfalls whose final `next()` callback returns the event's result type. `TypertClientEventListener` derives the Client listener from that same `Events` member while preserving signals, optional and readonly fields, arrays, callbacks, and result types. `TypertClientRemote` exposes only `$mount()` and `$on()`; event transport remains private to Gateway.

+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the declarations stay compiler-independent and where each contract is enforced; the programming model is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The package keeps reflection out of the compiler: decorator initializers retain markers in a module-private `WeakMap` keyed by the Service prototype, with no constructor symbols, prototype properties, parameter metadata, or runtime reflection fields. Full parameter, result, lookup, and schema reflection is the Typert build pipeline's job, delivered through `InvocationDescriptor`.
+
+### Remote markers
+
+`@Remote` and `@RemoteScope` schedule an initializer that records the method name, an optional export name, and the invocation mode; `remoteMethods(service)` returns a detached declaration-order snapshot that the Gateway's source-mode fallback reads. Markers require public, non-static instance methods with string names, and conflicting markers on one method are rejected.
+
+### Protocol maps and descriptors
+
+The merge-extensible protocol maps keep static associations in the type system, while runtime providers register resolution with `ctx.typert`; the map names and shapes live in [`src/types.ts`](src/types.ts). `InvocationDescriptor` is the shared runtime form consumed by the registry, the Gateway, and the Client Remote, covering direct and Context receivers, JSON and lookup parameters, scope projections, cancellation, and result codecs.
+
+### Wire identity grammar
+
+Every namespace, method, lookup, and Context segment must satisfy `isTypertRemoteSegment()`, so generated names cross the shared RPC carrier unchanged. Strict codecs carry generated schemas; `src-json` codecs identify the weaker source-launch path.

-该包提供不依赖编译器的声明，由业务包、生成的 Typert 产物、宿主网关和客户端 API 共享。它负责 Remote 服务基类、装饰器、显式绑定回退、可通过声明合并扩展的协议映射、调用描述符、编解码器和提供方约定；它不执行 TypeScript 分析，也不注册具体 Cordis 服务。
+## 概述
 
-## Remote 声明
+借助 `dsh-typert-protocol`，业务包可以向 Remote 客户端暴露 Host 方法：用 `@Remote`（作用域接收者用 `@RemoteScope`）标记方法，把服务绑定到 wire 命名空间，并通过可合并扩展的协议映射把 Host 对象与作用域 Context 关联到 wire identity。生成产物、Host Gateway 与 Client API 消费同一套调用描述符、编解码器与提供方约定，因此一套声明在每个 face 上保持一致。本包不注册任何 Cordis 服务，也不运行 TypeScript 分析；它只声明类型与装饰器标记。
 
-- `@Remote` 将公开实例方法标记为可在其注册的 Cordis 服务上直接调用。
-- `@RemoteScope(key)` 标记接收者选自合并声明的作用域 Context 类型的方法。
-- `TypertRemoteService` 将传给 `super(ctx, serviceKey, options?)` 的 Cordis 键绑定到同一默认协议命名空间。
-- `bindTypertRemote(this, serviceKey, options?)` 为无法继承 `TypertRemoteService` 的服务提供同样可见且冻结的绑定。

-## Typert 协议
+<a id="use-this-package"></a>
+## 使用本包
 
-业务包扩展 `TypertLookupMap` 和 `TypertContextMap`，以关联宿主对象或作用域 Context 与其协议身份。生成的产物扩展 `TypertRemoteMap`、`TypertRemoteScopeMap` 和 `TypertRemoteNamespaceMap`，使客户端导入后仅暴露选定的 Remote 方法。`InvocationDescriptor` 是供注册表、网关和客户端 Remote 使用的共享运行时形式。
+本包供向 Remote 客户端暴露 Host 能力的业务包与装配维护者使用。它是一个声明库：标记方法、绑定服务，其余交给生成的流水线与 Gateway。
 
-Host 装配以转发给消费端的 Cordis 事件扩展 `TypertRemoteEventSelection`，从而收窄 `ctx.remote.$on` 的键面。`TypertForwardableEvent` 接受无作用域且返回 `void` 的通知，以及最后一个 `next()` 回调返回事件结果类型的异步作用域 waterfall。`TypertClientEventListener` 从同一条 `Events` 成员派生 Client listener：在 `TypertLookupMap` 与 `TypertContextMap` 中使用同名 key 声明的 Host subject 类型会变为 Client `Context`，同时保留 `AbortSignal`、可选与只读对象字段、数组、回调和结果类型。`TypertClientRemote` 只公开 `$mount()` 与 `$on()`；事件传输由 Gateway 私有持有。
+### 暴露 Host 方法
 
-查找包与 Context 包同时负责该约定的两侧：声明合并提供静态关联，运行时提供方向 `ctx.typert` 注册身份解析。Host 与 Client Context adapter 都提供 `Context -> wire identity` 和 `wire identity -> Context`；Host adapter 还提供稳定的 wire 声明，Host 组合可以覆盖其同步或异步 resolver。策略拒绝可用 `TypertLookupFailure` 携带由边界适配器拥有的失败值。严格编解码器携带生成的 schema；`src-json` 编解码器标识约束更弱的源码启动路径。
+业务包用 `@Remote`（当接收者来自作用域 Context 时用 `@RemoteScope(key)`）标记一个公开实例方法，所属服务要么继承 `TypertRemoteService`，要么通过 `bindTypertRemote()` 声明 `typertRemote` 绑定：
 
+```text
+import { Remote, TypertRemoteService } from '@deepseek-ai/dsh-typert-protocol'
+
+export class GoalService extends TypertRemoteService {
+  @Remote
+  async create(agentId: string, objective: string): Promise<GoalResult> {
+    ...
+  }
+}
+```
+
+生成会把方法变为服务命名空间下的 wire 端点；Client 通过 `ctx.remote` 以类型化方法调用它（见 [API Gateway 参考](../../../docs/api-gateway.zh.md)）。方法把 `signal: AbortSignal` 声明为最后一个参数即可选择协作式取消——该信号是注入的，绝不会成为 JSON 参数或查找字段。
+
+### 把 Host 对象与 Context 关联到 wire identity
+
+复杂的 Host 对象不能直接跨 wire 传输。业务包通过可合并扩展的 `TypertLookupMap` 与 `TypertContextMap` 声明关联。Host 与 Client Context adapter 都把 `Context` 映射为 wire identity，也把该 identity 映射回 `Context`；Host adapter 还拥有稳定 wire 声明。Host 组合可以覆盖其同步或异步 resolver。策略拒绝可以抛出 `TypertLookupFailure`，把适配器拥有的失败值带给调用方。
+
+### 在 Client 侧接收转发的 Host 事件
+
+Host 装配以转发给消费端的 Cordis 事件扩展 `TypertRemoteEventSelection`，从而收窄 `ctx.remote.$on` 的键集。`TypertForwardableEvent` 接受无作用域且返回 `void` 的通知，以及最后一个 `next()` 回调返回事件结果类型的异步作用域 waterfall。`TypertClientEventListener` 从同一条 `Events` 成员派生 Client listener，并保留 signal、可选和只读字段、数组、回调与结果类型。`TypertClientRemote` 只公开 `$mount()` 与 `$on()`；事件传输仍由 Gateway 私有持有。

 # @deepseek-ai/dsh-typert-registry
 
 English | [中文](README.zh.md)
 
-Runtime registry for generated Typert artifacts. A contribution carries one package face's business reflection and optional live Zod schemas; `ctx.typert` registers both atomically and withdraws them with the calling Cordis fiber. TypeScript analysis and code generation live in [`dsh-typert-generator`](../generator/README.md).
+## Summary
 
-Package reflection is keyed by `<package>#<face>`. Schemas are keyed by `<package>#<name>` and retain the producer's Zod instance. JSON Schema is computed on demand at the consumer edge.
+`dsh-typert-registry` makes generated Typert artifacts queryable at runtime: each package's reflection — services, events, and objects — its live Zod schemas, and Remote invocation descriptors live under stable keys that consumers can query or resolve on demand. Registrations are atomic and fiber-scoped: a contribution lands whole or not at all and is withdrawn automatically when the registering component unloads. The same service hosts the lookup and scoped-Context provider registries that Remote calls resolve through. It performs no TypeScript analysis and generates no schemas; the generator and the loader handle those.
 
-## Public API
+## Table of Contents
 
-- `TypertRegistry` is the default plugin and provides `ctx.typert`.
-- `ctx.typert.lookups.register()` registers the wire declaration and default resolver owned by the business package; `configure()` registers a resolver owned by Host composition that may run asynchronously. Their lifetimes are independent: configuration may precede the provider, and unloading the configuration restores the default policy.
-- `ctx.typert.contexts.registerHost()` installs one bidirectional Host Context adapter and its wire declaration; `configureHost()` can replace only its resolver. `registerClient()` installs the bidirectional Client adapter for the same merge-declared kind. `identifyHost(ctx)` asks the existing Host adapter set for the single kind and identity represented by a live Context and rejects ambiguous recognition.
-- `register(contribution)` rejects malformed identities and duplicate package-face or schema keys before committing anything, then returns the exact Cordis effect disposer.
-- `get(key)`, `resolve(key)`, and `list(filter?)` query live schemas. `resolve()` distinguishes a malformed key, an absent package, and a package that contributes no schema under that name.
-- `getPackage(packageName, face?)` and `listPackages(filter?)` query generated service, event, and object reflection; the default face is `host`.
-- `toJSONSchema(key, params?)` projects a live schema with `z.toJSONSchema()` without caching the result.
-- `typertKey()` and `typertPackageKey()` compose the two stable identity forms.

-The `@deepseek-ai/dsh-typert-registry/types` subpath contains the pure contribution and record contracts. [`dsh-typert-loader`](../loader/README.md) discovers and registers generated host artifacts in Loader compositions; direct `ctx.typert.register()` supports other composition owners.
+-----
 
+<a id="use-this-package"></a>
+## Use this package
+
+Mount the registry in any Host or Client composition that stores or consumes generated Typert artifacts; it provides `ctx.typert`. There is no configuration.
+
+### Minimal setup
+
+Load the registry plugin; the Client face is installed the same way by the Client runtime's own metadata, and both faces run the same implementation:
+
+```yaml
+- name: '@deepseek-ai/dsh-typert-registry'
+```
+
+### Querying schemas and reflection
+
+Consumers read schemas with `get(key)`, `resolve(key)`, or `list(filter?)` and package reflection with `getPackage(name, face?)` or `listPackages(filter?)`. `resolve()` distinguishes a malformed key, an absent package, and a registered package that contributes no schema under that name, each with its own error. `toJSONSchema(key)` projects a live Zod schema to JSON Schema without caching.
+
+### Registering a contribution
+
+Generated artifacts register through the [loader](../loader/README.md) in Loader compositions; any other owner calls `ctx.typert.register(contribution)` directly and receives the exact disposer that withdraws it. Duplicate package-face identities, schema keys, invocation ids, or endpoints reject the whole batch before anything is committed.
+
+### Lookup and Context providers
+
+Remote calls resolve Host objects and scoped Contexts through `ctx.typert.lookups` and `ctx.typert.contexts`. `registerHost()` installs one bidirectional Host Context adapter and its wire declaration, while `configureHost()` replaces only its resolver. `registerClient()` installs the bidirectional Client adapter for the same merge-declared kind. `identifyHost(ctx)` asks the Host adapters for the single kind and identity represented by a live Context and rejects ambiguous recognition.
+

+
+<a id="understand-the-implementation"></a>
+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the registry stores and owns contributions; the consumer API is covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The registry is built on one principle: a contribution is one atomic, fiber-owned commit. `register()` validates the package-face identity, schemas, and invocation descriptors first, then commits everything under a single Cordis effect whose disposer withdraws exactly that contribution. Duplicate identities fail at the owning operation boundary before any state changes.
+
+### Sub-registries
+
+- `ctx.typert.local` — current-environment invocation definitions, including `hasSeen()` history for source-mode fallback.
+- `ctx.typert.remotes` — consumer-selected contributions mounted in the calling fiber.
+- `ctx.typert.lookups` — lookup providers plus composition-owned resolver overrides per key.
+- `ctx.typert.contexts` — Host Context providers and Client Context binders per scoped key.
+
+Each sub-registry publishes `TypertRegistryChange` events to subscribed listeners; a throwing listener is logged and does not stop later listeners.
+
+### Identity and validation
+
+Keys are stable: `<package>#<face>` for reflection, `<package>#<name>` for schemas, and `<namespace>/<method>` for endpoints. Validation rejects names containing `#`, wire names outside the RPC segment grammar, duplicate keys, and lookup definitions whose wire declaration changes during the registry lifetime; strict codecs must carry a parseable schema.

-生成的 Typert 产物所用的运行时注册表。每个注册项包含某个包在一个 face 上的业务反射信息，以及可选的运行时 Zod schema；`ctx.typert` 会以原子方式同时注册两者，并在发起调用的 Cordis fiber 释放时一并移除它们。TypeScript 分析和代码生成由 [`dsh-typert-generator`](../generator/README.zh.md) 负责。
+## 概述
 
-包反射信息以 `<package>#<face>` 为键。schema 以 `<package>#<name>` 为键，并保留生成方的 Zod 实例。系统按需在消费方边界计算 JSON Schema。
+`dsh-typert-registry` 让生成的 Typert 产物在运行时可按需查询：每个包的反射——服务、事件与对象——其实时 Zod schema 与 Remote 调用描述符都保存在稳定键下，消费方可以按需查询或解析。注册是原子且按 fiber 作用域的：贡献要么整体落地要么完全不落地，并在注册组件卸载时自动撤销。同一服务还托管 Remote 调用所经由的 lookup 与作用域 Context 提供方注册表。它不执行 TypeScript 分析，也不生成 schema；这些由生成器与 loader 负责。
 
-## 公开 API
+## 目录
 
-- `TypertRegistry` 是默认插件，并提供 `ctx.typert`。
-- `ctx.typert.lookups.register()` 注册由业务包拥有的协议声明和默认解析器；`configure()` 注册由宿主组合拥有且可异步执行的解析器。两者的生命周期相互独立：配置可以先于提供方注册，卸载配置会恢复默认策略。
-- `ctx.typert.contexts.registerHost()` 安装双向 Host Context adapter 及其 wire 声明，`configureHost()` 只替换其中的 resolver。`registerClient()` 为同一个声明合并 kind 安装双向 Client adapter。`identifyHost(ctx)` 通过既有 Host adapter 集合识别活 Context 所代表的唯一 kind 与 identity，并拒绝多个 adapter 同时识别的歧义。
-- `register(contribution)` 会在提交任何内容之前拒绝格式错误的标识，以及重复的包与 face 组合键或 schema 键，随后返回 Cordis effect 提供的同一资源释放函数。
-- `get(key)`、`resolve(key)` 和 `list(filter?)` 查询当前有效的 schema。`resolve()` 能区分格式错误的键、未注册的包，以及已注册但未以该名称提供 schema 的包。
-- `getPackage(packageName, face?)` 和 `listPackages(filter?)` 查询生成的服务、事件和对象反射信息；默认 face 为 `host`。
-- `toJSONSchema(key, params?)` 使用 `z.toJSONSchema()` 投影当前有效的 schema，且不缓存结果。
-- `typertKey()` 和 `typertPackageKey()` 构造两种稳定的标识形式。

-`@deepseek-ai/dsh-typert-registry/types` 子路径包含注册项和记录的纯类型约定。[`dsh-typert-loader`](../loader/README.zh.md) 会在 Loader 组合中发现并注册生成的宿主侧产物；其他组合所有者可以直接调用 `ctx.typert.register()`。

+<a id="use-this-package"></a>
+## 使用本包
+
+在存储或消费生成 Typert 产物的任何 Host 或 Client 组合中挂载本注册表；它提供 `ctx.typert`。没有配置。
+
+### 最小设置
+
+加载注册表插件；Client face 由 Client 运行时自身的元数据以同样方式安装，两个 face 运行同一实现：
+
+```yaml
+- name: '@deepseek-ai/dsh-typert-registry'
+```
+
+### 查询 schema 与反射
+
+消费方用 `get(key)`、`resolve(key)` 或 `list(filter?)` 读取 schema，用 `getPackage(name, face?)` 或 `listPackages(filter?)` 读取包反射。`resolve()` 能区分格式错误的键、未注册的包，以及已注册但未以该名称提供 schema 的包，各自给出不同的错误。`toJSONSchema(key)` 把实时 Zod schema 投影为 JSON Schema，且不缓存结果。
+
+### 注册贡献
+
+生成产物在 Loader 组合中通过 [loader](../loader/README.zh.md) 注册；其他所有者直接调用 `ctx.typert.register(contribution)`，并获得撤销它的同一资源释放函数。重复的包与 face 组合键、schema 键、调用 id 或端点会在提交任何内容之前拒绝整个批次。
+
+### Lookup 与 Context 提供方
+
+Remote 调用通过 `ctx.typert.lookups` 与 `ctx.typert.contexts` 解析 Host 对象与作用域 Context。`registerHost()` 安装一个双向 Host Context adapter 及其 wire 声明，`configureHost()` 只替换其中的 resolver。`registerClient()` 为同一个 merge-declared kind 安装双向 Client adapter。`identifyHost(ctx)` 通过 Host adapter 识别活 Context 所代表的唯一 kind 与 identity，并拒绝歧义识别。

+
+本节解释注册表如何存储与拥有贡献；消费方 API 已在[使用本包](#use-this-package)中说明。
+
+### 设计理念
+
+注册表建立在一个原则之上：贡献是一次原子、由 fiber 拥有的提交。`register()` 先校验包与 face 组合键、schema 与调用描述符，再在单个 Cordis effect 下提交全部内容，该 effect 的资源释放函数精确撤销这一贡献。重复标识在拥有该操作的所有权边界失败，此时任何状态都未改变。
+
+### 子注册表
+
+- `ctx.typert.local`——当前环境的调用定义，含供源码模式回退使用的 `hasSeen()` 历史。
+- `ctx.typert.remotes`——在调用方 fiber 中挂载的、由消费方选中的贡献。
+- `ctx.typert.lookups`——lookup 提供方，以及按键配置的组合方解析器覆盖。
+- `ctx.typert.contexts`——按作用域键配置的 Host Context 提供方与 Client Context 绑定器。
+
+每个子注册表都会向已订阅的监听器发布 `TypertRegistryChange` 事件；抛异常的监听器会被记录日志，且不会阻止后续监听器。
+
+### 标识与校验
+
+键是稳定的：反射用 `<package>#<face>`，schema 用 `<package>#<name>`，端点用 `<namespace>/<method>`。校验会拒绝含 `#` 的名称、超出 RPC 端点段文法的 wire 名称、重复键，以及在其注册表生命周期内改变 wire 声明的 lookup 定义；严格编解码器必须携带可解析的 schema。

 English | [中文](README.zh.md)
 
-These zero-dependency packages provide small primitives shared by multiple capability families. Business semantics remain with each consuming capability.
+## Summary
+
+The `util/` group gives capability packages shared mechanical primitives instead of duplicate implementations. It covers atomic writes, branded ids, UUIDs, Harness-home paths, launch environments, native commands, output retention, and timeout handling. Every package here is a library: it registers no service or event, and the consuming capability retains the business semantics.

-Zero-dependency atomic file replacement shared by file-backed stores that must never leave partial, symlink-hijacked, or wider-than-intended content on disk — the user-settings document (`dsh-settings-file`) and the credentials store (`dsh-credentials-local`).
+## Summary
 
-## Surface
+`dsh-atomic-write` replaces a file's contents in one atomic step: readers of the target always observe either the complete old content or the complete new content, never a partial write. It also serializes read-modify-write cycles across processes with a writer lock, so concurrent writers of one file cannot resurrect each other's state. The caller states the permission bits for every replacement and the fresh inode carries them through the swap, so replacing a wider-permission file narrows it without a chmod race. It is a zero-dependency library shared by file-backed stores such as the user-settings document and the credentials store; a `cordis.yml` cannot load it, and crash durability is the caller's policy because there is no `fsync`.

+## Use this package
+
+Use `writeFileAtomic` when a file-backed store must replace one already-rendered string without ever exposing a partial, symlink-hijacked, or wider-permission state, and `withFileLock` when several processes read-modify-write the same file. The smallest path is one call with the final content and the replacement's permission bits.
+
+### Writing a file atomically
 
 ```ts
-import { withFileLock, writeFileAtomic } from '@deepseek-ai/dsh-atomic-write'
+import { writeFileAtomic } from '@deepseek-ai/dsh-atomic-write'
 
 declare const text: string
-declare const render: (previous: string) => string
-
 await writeFileAtomic('/home/u/.dsh/settings.yaml', text, { mode: 0o600 })
+```
+
+Parent directories are created as needed, and readers observe either the old or the new complete content. On any failure the temporary file is removed and the failure is rethrown, so a failed replacement leaves the target untouched.
+
+### Coordinating writers
+
+For a read-render-commit cycle that a bare atomic commit cannot make safe on its own, hold the writer lock around the operation:
+
+```text
+import { withFileLock, writeFileAtomic } from '@deepseek-ai/dsh-atomic-write'
+
+declare const render: (previous: string) => string
+declare const readCurrent: () => Promise<string>
 
-// Read-modify-write against the same file from several processes.
 await withFileLock('/home/u/.dsh/settings.yaml', async () => {
-  await writeFileAtomic('/home/u/.dsh/settings.yaml', render(text), { mode: 0o600 })
+  const previous = await readCurrent()
+  await writeFileAtomic('/home/u/.dsh/settings.yaml', render(previous), { mode: 0o600 })
 })
 ```
 
-`writeFileAtomic` commits one already-rendered string. The contract, in the order failures would exploit it:
+Only writers contend — readers never take the lock — and a contender backs off exponentially and fails with a timed-out error rather than blocking forever. How long a contender waits is stated per call through `waitMs`: the default is sized for file work alone, so a holder whose cycle includes a network round trip — a credential mutation that refreshes an expired token — states a longer one, because leaving the default would fail every other writer of that file for the duration. The retry cadence stays fixed. A contender never removes an existing lock, because file age cannot prove that its owner stopped.
 
-- **Exclusive-create temp** (`wx`, random suffix): the open refuses to follow a symlink planted at a guessable temp path.
-- **The fresh inode carries `mode` through the rename**: replacing a wider-permission file narrows it without a chmod race. `mode` is required so the permission decision stays visible at every call site (subject to the process umask, like every fresh inode).
-- **`rename` replaces a symlinked target itself**, never writing through to its referent.
-- **Same-directory sibling** keeps the rename on one filesystem, so the swap stays atomic.
-- Parent directories are created; on any failure the temp is removed and the failure rethrown; readers observe either the old or the new complete content.
+### Failures to plan for
 
-`withFileLock` serializes the writers of one file across processes, for the read-render-commit cycles a bare atomic commit cannot make safe on its own. The lock is a `wx`-created `<filename>.lock` sibling, so readers never contend; waiters back off exponentially and fail with a timeout rather than block forever. `EEXIST` identifies contention directly; `EPERM` does so only when a fresh `lstat` confirms that the lock path exists, covering Windows exclusive-create behavior without hiding an unrelated permission failure. A contender never removes the existing lock: age cannot distinguish a crashed owner from a paused live writer.
+The lock's parent directory must already exist, so `withFileLock` rejects an invalid parent hierarchy before running the operation. A process that exits while holding the lock leaves the lock sibling behind; later writers time out, and an operator removes it only after verifying that no writer still owns it.
 
-How long a contender waits is a property of the operation the holder runs, so it is stated per call through `waitMs`. The default is sized for file work alone; a holder whose cycle includes a network round trip — a credential mutation that refreshes an expired token — states a longer one, because leaving the default would fail every other writer of that file for the duration. The retry cadence stays fixed: it governs how often a contender asks, which no caller has a reason to vary.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+The package is built on one separation: the atomic commit owns the swap, and the writer lock owns cross-process ordering.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | `writeFileAtomic` and `withFileLock`, the package's whole surface |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; the replacement contract is exercised by unit tests) |
+
+### Write path
+
+`writeFileAtomic` writes a random-suffix sibling opened with exclusive create (`wx`), then renames it over the target. The exclusive open refuses to follow a symlink planted at a guessable temp path; the same-directory sibling keeps the rename on one filesystem; and the rename replaces a symlinked target itself instead of writing through to its referent.
+
+`withFileLock` creates a `<filename>.lock` sibling with `wx`. `EEXIST` identifies contention directly; `EPERM` does so only when a fresh `lstat` confirms the lock path exists, covering Windows exclusive-create behavior without hiding an unrelated permission failure. The lock records its creator's PID and is removed by the holder in a `finally`; contention backs off exponentially and fails when the per-call `waitMs` deadline (default two seconds) passes.
+
+### Why the swap stays safe
+
+- **Fresh inode, caller-stated mode** — the temp carries `mode` through the rename, so narrowing a wider-permission file has no chmod race. `mode` is required so the permission decision stays visible at every call site.
+- **Readers never contend** — the rename commit is atomic, so a reader needs no lock.
+- **A contender never deletes a lock** — age cannot distinguish a crashed owner from a paused live writer; recovery is an operator action.

-零依赖的原子文件替换，供绝不允许在磁盘上留下不完整、被符号链接劫持或权限过宽内容的文件型存储共用：用户设置文档（`dsh-settings-file`）与凭据存储（`dsh-credentials-local`）。
+## 概述
 
-## 接口面
+`dsh-atomic-write` 一步原子地替换文件内容：目标的读取方总是看到完整的旧内容或完整的新内容，绝不看到部分写入。它还通过写锁跨进程串行化读-渲染-提交循环，因此同一文件的并发写入方无法复活彼此替换掉的状态。调用方为每次替换声明权限位，全新 inode 会带着这些权限位走完交换，因此替换权限过宽的旧文件时会直接收窄，不存在 chmod 竞态。它是一个零依赖库，由用户设置文档与凭据存储这类文件型存储共享；`cordis.yml` 无法加载它，而且由于没有 `fsync`，崩溃持久性由调用方负责。

+## 使用本包
+
+当文件型存储必须替换一份已渲染好的字符串、且绝不允许暴露部分写入、符号链接劫持或权限过宽状态时，使用 `writeFileAtomic`；当多个进程读写同一文件时，使用 `withFileLock`。最小路径是一次调用，传入最终内容与替换 inode 的权限位。
+
+### 原子写入文件
 
 ```ts
-import { withFileLock, writeFileAtomic } from '@deepseek-ai/dsh-atomic-write'
+import { writeFileAtomic } from '@deepseek-ai/dsh-atomic-write'
 
 declare const text: string
-declare const render: (previous: string) => string
-
 await writeFileAtomic('/home/u/.dsh/settings.yaml', text, { mode: 0o600 })
+```
+
+父目录会按需创建，读取方只会观察到旧内容或完整的新内容。任何失败都会移除临时文件并重新抛出该失败，因此一次失败的替换不会改动目标文件。
+
+### 协调写入方
+
+对于单靠原子提交无法保证安全的读-渲染-提交循环，请在操作期间持有写锁：
+
+```text
+import { withFileLock, writeFileAtomic } from '@deepseek-ai/dsh-atomic-write'
+
+declare const render: (previous: string) => string
+declare const readCurrent: () => Promise<string>
 
-// Read-modify-write against the same file from several processes.
 await withFileLock('/home/u/.dsh/settings.yaml', async () => {
-  await writeFileAtomic('/home/u/.dsh/settings.yaml', render(text), { mode: 0o600 })
+  const previous = await readCurrent()
+  await writeFileAtomic('/home/u/.dsh/settings.yaml', render(previous), { mode: 0o600 })
 })
 ```
 
-`writeFileAtomic` 提交一份已经渲染好的字符串。约定按故障利用它的先后顺序列出：
+只有写入方会竞争——读取方从不取锁——竞争者按指数退避，超时即以错误失败，而不是无限阻塞。竞争者等待多久由每次调用经 `waitMs` 声明：默认值只按纯文件工作量级选定，因此持锁方循环若包含一次网络往返——例如刷新过期 token 的凭据变更——就应声明更长的值，否则该文件的其他写入方在这段时间内都会失败。退避节奏保持固定。竞争者绝不移除已有锁，因为文件存续时间无法证明其持有者已经停止。
 
-- **独占创建临时文件**（`wx` + 随机后缀）：open 拒绝跟随预先埋在可猜测临时路径上的符号链接。
-- **全新 inode 携带 `mode` 走完 rename**：替换权限过宽的旧文件时直接收窄，不存在 chmod 竞态。`mode` 为必填，让权限决策始终可见于每个调用点（与所有新建 inode 一样受进程 umask 影响）。
-- **`rename` 替换的是符号链接目标本身**，绝不写穿到其指向的文件。
-- **同目录兄弟文件**保证 rename 落在同一文件系统上，交换保持原子。
-- 自动创建父目录；任何失败都会移除临时文件并重新抛出该失败；读取方只会观察到旧内容或完整的新内容。
+### 需要规划的失败
 
-`withFileLock` 跨进程串行化同一文件的写入方，服务于单靠原子提交无法保证安全的读-渲染-提交循环。锁是以 `wx` 创建的同目录 `<filename>.lock`，因此读取方从不参与竞争；等待方按指数退避，超时即失败而非无限阻塞。`EEXIST` 直接表示竞争；只有一次新的 `lstat` 确认锁路径存在时，`EPERM` 才表示竞争，从而兼容 Windows 的独占创建行为，又不掩盖无关的权限故障。竞争者绝不移除现有锁：锁龄无法区分已经崩溃的所有者与被暂停但仍存活的写入方。
+锁的父目录必须已经存在，因此 `withFileLock` 会在运行操作之前拒绝无效的父目录层级。持锁进程退出时会把锁文件留在原地；后续写入方超时失败，操作者只有在确认没有写入方仍持有该锁后才会移除它。
 
-等待多久是持锁方所跑操作的属性，因此由每次调用经 `waitMs` 声明。默认值只按纯文件工作量级选定；若持锁方的循环包含一次网络往返——例如刷新过期 token 的凭据变更——就应声明更长的值，否则该文件的其他写入方会在这段时间内全部失败。退避节奏保持固定：它决定竞争者多久问一次，调用方没有理由改变它。

-The `Branded<B>` nominal-typing primitive — a tiny, **type-only** package (no runtime code, no harness-package dependency) shared by every package that owns a cross-boundary id.
+## Summary
 
-## What `Branded` is
+`dsh-brand` makes structurally identical strings non-interchangeable at the type level with its `Branded<B>` primitive: a `SessionId` cannot be passed where a `CallId` is expected even though both are plain `string`s at runtime. Comparison, logging, JSON serialization, and the wire format all behave exactly as for ordinary strings because the brand is erased at compile time. It is a type-only package with no runtime code and no dependency on other harness packages, so any package can brand the ids it owns without importing an unrelated capability package. Packages that own a cross-package id — `CallId` in `dsh-llm`, the shared agent/session `SessionId`, `JobId` in `dsh-jobs` — brand that id and construct it through a per-id factory.

+Brand the ids a package owns when they cross a package boundary and could plausibly be confused with another package's ids; not every string needs a brand.

-Construction goes through the per-id factory in the owning package. Comparison, logging, JSON serialization, and the wire format behave as for an ordinary string; the brand is erased at compile time.
+The factory is a plain cast with zero runtime cost. Once branded, the id flows through the codebase as an ordinary string: it compares, logs, serializes to JSON, and crosses the wire without any special handling.
 
-## Policy: brand ids that cross package boundaries
+### When to brand
 
-A package brands the ids it owns — `CallId` in `dsh-llm`, the shared agent/session `SessionId` in `dsh-session`, and `JobId` in `dsh-jobs`. Brand cross-package ids that could plausibly be confused; not every string needs one.

Do not brand every string: the cost is a factory at every construction site and a type import in every consumer, so ids that never leave their owning package do not earn it.

+
+The primitive is one intersection type: `string & { readonly [BRAND]: B }`, where `BRAND` is a module-private `unique symbol`.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | The `Branded<B>` type and the private `BRAND` symbol — the whole package |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; erasure is enforced by the compiler) |
+
+### How erasure works
+
+The symbol never exists at runtime: the type is erased during compilation, so a branded value is a plain string with no tag, no prototype, and no runtime check. Construction is a cast inside the owning package's factory, so a brand is only ever created where the owning package says it is.
+
+### Why it stays dependency-free
+
+Keeping `Branded` in its own package means `dsh-jobs` can brand `JobId` without importing an unrelated capability package just to reach the primitive, and the brand vocabulary has exactly one owner.

+## Summary
+
 Zero-dependency browser-safe UUID and byte-encoding helpers. UUID minting uses `crypto.getRandomValues`, the one random primitive every shipped context provides. `crypto.randomUUID` is a secure-context Web API: a page or worker served over plain HTTP on a LAN address (the browser preview deployment) has no such method, so code that must run there cannot call it. The repository-wide `no-restricted-properties` lint rule points `crypto.randomUUID` callers here; Node-only code importing `randomUUID` from `node:crypto` stays as it is.

-Shared filesystem path helpers for DeepSeek Harness user data.
+## Summary
 
-## DSH home
+`dsh-home-paths` resolves the single DeepSeek Harness home that all user data lives under, and joins child paths onto it, so every product package agrees on where its files go. Precedence is explicit: a configured path wins, then `$DSH_HOME`, then `~/.dsh`, and an empty or whitespace-only `$DSH_HOME` counts as unset. The package also expands `~`, `~/...`, and `~\...` prefixes against the operating-system home, and canonicalizes a watch target so a native filesystem watcher gets one stable path spelling even when the final components do not exist yet. It is a zero-dependency library that product packages import directly; a `cordis.yml` cannot load it.
 
-`resolveDshHome()` resolves the single-root DeepSeek Harness home. Precedence, highest first: an explicit configured path, `$DSH_HOME`, then `~/.dsh`. The harness keeps all user data under one root.
+## Table of Contents
 
-`dshHomePath(...segments)` joins child segments onto that resolved home with Node's platform path rules. With no segments it returns the home itself.

-`dshHomeDisplay()` names an active root symbolically for user-facing paths: `~/.dsh` for the default home, `$DSH_HOME` for any configured home. It never leaks an absolute machine path.
+-----
 
-`DSH_HOME_DIR_NAME` owns the default user-data directory name: `.dsh`.
+<a id="use-this-package"></a>
+## Use this package
 
-`defaultDshHome()` returns the default DeepSeek Harness home by joining the operating-system home directory with `.dsh`, using Node's platform path rules.
+Use these helpers wherever a package must agree with the rest of the harness about where user data lives: resolve the home once, then derive every child path from it.
 
-`expandHomePath()` expands `~`, `~/...`, and Windows-style `~\...` prefixes against the operating-system home directory. It leaves non-tilde paths and `~user/...` untouched.
+### Resolving the home
 
-## Watch paths
+```ts
+import { resolveDshHome, dshHomePath } from '@deepseek-ai/dsh-home-paths'
 
-`canonicalizeWatchPath()` gives a native filesystem watcher one stable spelling of its target. It resolves the deepest existing ancestor through `fs.realpath()` and restores any missing suffix, so a file or directory may still be watched before it is created. In particular, Windows 8.3 aliases cannot be mixed with the long paths emitted by the native watcher backend.
+const home = resolveDshHome()                // configured path, else $DSH_HOME, else ~/.dsh
+const settings = dshHomePath('settings')     // join one child onto the resolved home
+```
 
-This package is intentionally small and harness-dep-free so product packages can share user-data path conventions without depending on one another.
+An explicit configured path has the highest precedence, then `$DSH_HOME`, then the default `~/.dsh`. An empty or whitespace-only `$DSH_HOME` is treated as unset, so a blank override never resolves the home to the current working directory.
+
+### Displaying a home
+
+For user-facing paths, render the root symbolically rather than as a machine path: the default home displays as `~/.dsh` and any configured home displays as `$DSH_HOME`. The display form never leaks an absolute machine path.
+
+### Expanding user paths
+
+`expandHomePath` expands a leading `~`, `~/`, or `~\` against the operating-system home and leaves everything else untouched — non-tilde paths and named-user forms such as `~alice/...` pass through unchanged.
+
+### Canonicalizing watch paths
+
+`canonicalizeWatchPath` gives a native filesystem watcher one canonical spelling of its target: the deepest existing ancestor is resolved through `realpath` and any missing suffix is restored, so a file or directory can be watched before it is created. This prevents Windows from treating a regular-file ancestor as ordinary absence, and prevents 8.3 short-name aliases from mixing with the long paths the native watcher backend emits.

+`resolveDshHome` reads the explicit override, then `$DSH_HOME`, then falls back to the operating-system home joined with `.dsh`. The chosen value is tilde-expanded and normalized to an absolute path; `dshHomePath` joins child segments with Node's platform path rules. `dshHomeDisplay` compares the resolved path against the default root and returns the symbolic label, so a configured home never leaks its absolute path.
+
+### Canonicalization mechanics
+
+`canonicalizeWatchPath` walks up from the target until it finds an existing ancestor, resolves it with `realpath`, proves it is an enumerable directory, and restores the missing suffix. Errors other than absence propagate, and a missing-suffix ancestor that is not a directory is rejected.

-DeepSeek Harness 用户数据的共享文件系统路径辅助工具。
+## 概述
 
-## DSH 主目录
+`dsh-home-paths` 解析所有用户数据所在的统一 DeepSeek Harness 主目录，并把子路径拼接上去，让每个产品包都就文件存放位置达成一致。优先级是显式的：显式配置的路径优先，然后是 `$DSH_HOME`，最后是 `~/.dsh`；空或仅含空白的 `$DSH_HOME` 视为未设置。该包还针对操作系统主目录展开 `~`、`~/...` 与 `~\...` 前缀，并规范化监听目标，让原生文件系统 watcher 即使在最终路径段尚不存在时也能获得一种稳定的路径写法。它是一个零依赖库，由产品包直接导入；`cordis.yml` 无法加载它。
 
-`resolveDshHome()` 解析 DeepSeek Harness 的单根主目录。优先级从高到低为：显式配置的路径、`$DSH_HOME`、`~/.dsh`。harness 将所有用户数据保存在同一根目录下。
+## 目录
 
-`dshHomePath(...segments)` 使用 Node 的平台路径规则，将子路径段拼接到解析后的主目录下。不传入任何路径段时，返回主目录本身。
+- [使用本包](#use-this-package)
+- [理解实现](#understand-the-implementation)
+- [进一步探索](#further-exploration)
+- [已知限制与延期工作](#known-limitations-and-deferred-work)
+- [开发备注](#dev-note)
 
-`dshHomeDisplay()` 以符号方式表示当前根目录，用于面向用户的路径：默认主目录表示为 `~/.dsh`，任何已配置的主目录表示为 `$DSH_HOME`。它绝不会泄露机器的绝对路径。
+-----
 
-`DSH_HOME_DIR_NAME` 定义默认用户数据目录名：`.dsh`。
+<a id="use-this-package"></a>
+## 使用本包
 
-`defaultDshHome()` 使用 Node 的平台路径规则，将操作系统主目录与 `.dsh` 拼接，并返回默认 DeepSeek Harness 主目录。
+当包必须与 harness 的其他部分就用户数据存放位置达成一致时使用这些辅助函数：先解析一次主目录，再从中派生所有子路径。
 
-`expandHomePath()` 使用操作系统主目录展开 `~`、`~/...` 和 Windows 风格的 `~\...` 前缀。它会保留非波浪号路径和 `~user/...` 原样不变。
+### 解析主目录
 
-## 监听路径
+```ts
+import { resolveDshHome, dshHomePath } from '@deepseek-ai/dsh-home-paths'
 
-`canonicalizeWatchPath()` 为原生文件系统 watcher 提供一种稳定的目标路径表示。它通过 `fs.realpath()` 解析层级最深的现有祖先路径，再拼回缺失的后缀，因此即使文件或目录尚未创建也仍可监听。尤其是，Windows 8.3 别名不能与原生 watcher 后端发出的长路径混用。
+const home = resolveDshHome()                // configured path, else $DSH_HOME, else ~/.dsh
+const settings = dshHomePath('settings')     // join one child onto the resolved home
+```
 
-该包刻意保持规模小且不依赖 harness，以便产品包共享用户数据路径约定，而不必彼此依赖。
+显式配置的路径优先级最高，然后是 `$DSH_HOME`，最后是默认的 `~/.dsh`。空或仅含空白的 `$DSH_HOME` 视为未设置，因此空白的覆盖值绝不会把主目录解析到当前工作目录。
 
-## 已知限制与暂缓事项
+### 展示主目录
 
-- **展开范围刻意保持狭窄**：只有单独的 `~`、`~/...` 和 `~\...` 使用当前操作系统主目录；`~alice/...` 等指定用户的形式、环境变量和 shell 表达式保持不变。
-- **规范化会读取，但绝不修改**：`canonicalizeWatchPath()` 会执行 `realpath` 探测，并传播除路径不存在以外的错误；调用方仍负责目录创建、权限，以及对结果路径应用信任策略。
+面向用户的路径请以符号形式渲染根目录，而不是机器路径：默认主目录显示为 `~/.dsh`，任何已配置的主目录显示为 `$DSH_HOME`。展示形式绝不会泄露机器的绝对路径。
+
+### 展开用户路径
+
+`expandHomePath` 针对操作系统主目录展开开头的 `~`、`~/` 或 `~\`，其余内容原样保留——非波浪号路径以及 `~alice/...` 等指定用户的形式不做任何改动。
+
+### 规范化监听路径
+
+`canonicalizeWatchPath` 为原生文件系统 watcher 提供目标路径的一种规范化写法：先通过 `realpath` 解析层级最深的现有祖先，再拼回缺失的后缀，因此文件或目录在创建之前就可以被监听。这可以防止 Windows 把普通文件祖先当作普通缺失处理，也防止 8.3 短名别名与原生 watcher 后端发出的长路径混用。

-This run's environment as one immutable snapshot that remembers **which layer supplied each value**. Consumers resolve user-facing values against it instead of `process.env`, because the layers are not equally trusted and a flattened view cannot tell them apart.
+## Summary
 
-| Layer | Source id | What it is |
-|---|---|---|
-| Inherited process environment | `process` | What the launching shell, CI job, or container passed in — this run's explicit intent |
-| `<invocation cwd>/.env` | `project-env` | The project the harness was launched in, which the product trusts to configure its own agent |
-| `$DSH_HOME/.env` | `user-env` | The user's own machine-level defaults |
+`dsh-launch-environment` freezes this run's environment at launch into an immutable snapshot that records which layer supplied each value. Resolving a name searches the layers from most to least trusted — the inherited process environment, the invoking directory's `.env`, then the Harness home's `.env` — so the winning value always carries its source. A caller can also resolve from a named subset of layers, which is a refusal rather than a demotion: omitted layers are unreachable no matter how trust ordering changes later. Values still reach `process.env` for config expressions and third-party libraries, but nothing the harness resolves treats that flattened view as authoritative. It is a zero-dependency library that product packages import directly; a `cordis.yml` cannot load it.
 
-Values do also reach `process.env` — a user's `--config` tree and third-party libraries read it — but that flattened view is not the authority for anything the harness resolves.

-`get(name)` searches every layer, most trusted first. `getFrom(name, sources)` searches only the named layers without changing that trust order.
+-----
 
-**Omitting a layer is a refusal, not a demotion** — a caller that must never accept a layer leaves it out of the list, so no future reordering can let it back in. The provider adapters name all three, because the product trusts the project it runs in; the mechanism exists for the decisions where that is not true.
+<a id="use-this-package"></a>
+## Use this package
 
-Names match the way the platform matches them: exactly on POSIX, case-insensitively on Windows. A case-sensitive lookup there would rank the wrong layer — a shell's `deepseek_api_key` and a project `.env`'s `DEEPSEEK_API_KEY` are one variable to the OS, and treating them as two would let the project win.
+Resolve user-facing values through the snapshot instead of `process.env` whenever the layers are not equally trusted — for example a credential override a caller must never take from a project directory.
+
+### Resolving a value
 
 ```ts
-import type { Context } from '@deepseek-ai/cordis'
 import { launchEnvironmentOf } from '@deepseek-ai/dsh-launch-environment'
 
-declare const ctx: Context
+declare const ctx: import('@deepseek-ai/cordis').Context
 const endpoint = launchEnvironmentOf(ctx).get('DEEPSEEK_BASE_URL')?.value
 ```
 
-`launchEnvironmentOf(ctx)` returns the launcher's snapshot when the product CLI booted the tree, and otherwise the inherited environment as the only layer. That fallback does not weaken the rules: an SDK host or a bare `cordis.yml` discovered no files, so everything it has really is the environment it was launched with.
+`get(name)` searches every layer, most trusted first. `getFrom(name, sources)` searches only the named layers without changing that trust order — a caller that must never accept a layer leaves it out of the list, so no future reordering can let it back in.
+
+### How layers rank
+
+| Layer | What it is |
+|---|---|
+| Inherited process environment | What the launching shell, CI job, or container passed in — this run's explicit intent |
+| `<invocation cwd>/.env` | The project the harness was launched in, which the product trusts to configure its own agent |

+<details>
+<summary>Implementation internals — click to expand</summary>
+
+The snapshot is built on one separation: the launcher owns which files exist, and the snapshot owns how values rank.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | `createLaunchEnvironmentSnapshot`, `launchEnvironmentOf`, and the `ctx.launchEnvironment` slot |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; the snapshot is frozen before any fiber starts) |
+
+### How the snapshot stays frozen
+
+`createLaunchEnvironmentSnapshot` copies every layer's values at construction, so a later mutation of the source object cannot change the snapshot. Lookups walk a canonical trust order regardless of construction order; on Windows, names are folded to uppercase before storage so case variants cannot split precedence.
+
+### What omission means
+
+`getFrom` filters by the canonical order, never by the caller's list order. Omitting a layer is a refusal: the value is unreachable through that call, which is the mechanism a caller uses when a layer must never influence a specific decision.

 ## Known Limitations and Deferred Work

The product launcher's [`.env` contract](../../boot/app-boot/README.md#profiles) rejects bootstrap variables before materialization.
-- **No per-workspace layer** — the project layer is the *invoking* directory, fixed at launch. A workspace selected later in the Web UI contributes nothing, deliberately: following it would let a model's own workspace change the harness environment mid-session.

-把本次运行的环境冻结为一份不可变快照，并记住**每个值来自哪一层**。消费方用它而不是 `process.env` 解析面向用户的值，因为各层的可信程度并不相同，而压平后的视图无法区分它们。

-| `$DSH_HOME/.env` | `user-env` | 用户自己的机器级默认值 |
+`dsh-launch-environment` 在启动时把本次运行的环境冻结为一份不可变快照，并记录每个值来自哪一层。解析一个名字会按可信度从高到低搜索各层——继承的进程环境、调用目录的 `.env`、然后是 Harness 主目录的 `.env`——因此胜出的值总是携带其来源。调用方也可以只从命名的层子集中解析，这是拒绝而非降级：无论之后信任顺序如何变化，被省略的层都不可达。这些值仍会进入 `process.env` 供配置表达式与第三方库使用，但 harness 解析任何内容都不把那份压平视图当作依据。它是一个零依赖库，由产品包直接导入；`cordis.yml` 无法加载它。

-- **没有按工作区划分的层**：项目层是*调用*目录，在启动时固定。之后在 Web UI 中选择的工作区不贡献任何内容，这是刻意的：跟随它等于让模型自己的工作区在会话中途改变 harness 的环境。

 English | [中文](README.zh.md)
 
-A **zero-dependency no-shell `execFile` runner** shared by host-native OS integrations: one `runNativeCommand(command, args, signal)` call spawns the executable directly (never a shell string), captures utf8 stdout/stderr, propagates the caller's abort into child termination, and hides the transient console window on Windows. Failures reject with the exit `code` and both captured streams attached, so callers classify (missing tool, cancelled, real failure) without re-running anything.
+## Summary
 
-Its two consumers are the host-side native integrations: the [`directory-picker-native`](../../host/directory-picker-native/README.md) backend's OS chooser commands and the gateway's open-with-default-application hand-off ([`dsh-host-apiproxy`](../../host/apiproxy/README.md) `host.openPath`). The `NativeCommandRunner` type is their injectable command boundary.
+`dsh-native-command` runs a host executable directly — never through a shell string — and captures its utf8 stdout and stderr. The caller's abort signal terminates the child, and on Windows the transient console window stays hidden. A failed run rejects with the exit code and both captured streams attached, so callers classify a missing tool, a cancellation, or a real failure without re-running anything. The host-side consumers are the native directory chooser and the open-with-default-application hand-off. It is a library, not a plugin: no `ctx`, no state, no events.

+## Use this package
+
+Use this runner when a host-side integration must execute one native command and needs its output, its failure, or both — and must never involve a shell.
+
+### Running a command
 
 ```ts
-import { runNativeCommand, type NativeCommandRunner } from '@deepseek-ai/dsh-native-command'
+import { runNativeCommand } from '@deepseek-ai/dsh-native-command'
+
+declare const script: string
+declare const signal: AbortSignal
+const { stdout, stderr } = await runNativeCommand('osascript', ['-e', script], signal)
 ```
 
+On exit 0 the call resolves with captured stdout and stderr. On any failure it rejects with the exit `code` and both captured streams attached, so a caller can tell a missing tool (`ENOENT`), a cancellation (`ABORT_ERR`), and a real command failure apart without re-running the command.
+
+### Injecting the command boundary
+
+The `NativeCommandRunner` type is the injectable command boundary for host integrations: pass the function (or a wrapper) where the integration needs a testable seam, so tests can substitute a fake runner.
+
+-----
+
+<a id="understand-the-implementation"></a>
+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+The runner is a thin wrapper over Node's `execFile` with three fixed choices: utf8 encoding, abort propagation, and Windows console hiding.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | `runNativeCommand` and the `NativeCommandRunner` type — the whole package |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; each run is one stateless child-process round trip) |
+
+### What execFile gives the runner
+
+`execFile` spawns the executable directly with an argv array — no shell string, no shell interpretation of the arguments. The `signal` option terminates the child when the caller's abort fires; `windowsHide` suppresses the transient console window on Windows. On a non-zero exit or spawn error, the callback attaches `code`, `stdout`, and `stderr` to the rejected error and keeps the original error as `cause`.

-A dependency-light **retention** library: bounded model-facing output for tools that must cap how much context they return. A caller feeds items or text chunks into a bounded object, then gets the retained content plus exact omission metadata.
+## Summary
 
-The library owns **only** the mechanical question *"what did we keep, and what did we omit?"*. Tool-specific code keeps its business semantics: file grouping, line numbering, exit codes, provider error states, per-line preview truncation, spill files, and the model-facing prose. This is the boundary the [Agent Note](../../../.agents/notes/implemented/architecture/2026-07-06-tool-result-retention-library.md) draws.
+`dsh-output-retention` bounds how much context a tool returns to the model: a caller feeds items or text chunks into a retainer, then gets back the retained content plus exact omission metadata. `ItemRetainer` caps an ordered list of logical units (paths, matches, sources) at a head budget; `TextRetainer` caps a byte-oriented text stream with head, tail, or head-and-tail windows and keeps UTF-8 boundaries valid at every cut. A standardized omission clause and a notice formatter give tools a consistent "results capped" footer while the tool owns the recovery guidance. The library answers only the mechanical question of what was kept and what was omitted — grouping, line numbering, spill files, and provider error states stay in the tool. It is a dependency-light library that tool packages import directly; a `cordis.yml` cannot load it.
 
-It is a **library, not a service or plugin**: no `ctx`, registers nothing, emits no events. The only state is per-retainer (one accumulation), never cross-call. Tool packages import it directly.

+## Use this package
+
+Use a retainer wherever a tool must cap how much of its result reaches the model, and report honestly what was dropped. Choose `ItemRetainer` for ordered logical units and `TextRetainer` for byte-oriented streams.
+
+### Bounding a list of items
 
 ```ts
-import {
-  ItemRetainer, TextRetainer,
-  describeOmitted, formatRetentionNotice,
-} from '@deepseek-ai/dsh-output-retention'
-import type {
-  Omitted, PushDecision, RetainedItems, RetainedText,
-  ItemRetentionStrategy, TextRetentionStrategy, RetentionNotice,
-} from '@deepseek-ai/dsh-output-retention'
-```
+import { ItemRetainer } from '@deepseek-ai/dsh-output-retention'
 
-| Export | Role |
-|---|---|
-| `ItemRetainer<T>` | Bounds ordered logical units (paths, grep matches, sources). `head` only. `push()` → `PushDecision`; `finish()` → `RetainedItems<T>`. |
-| `TextRetainer` | Bounds a byte-oriented text stream. `head` / `tail` / `headTail`, UTF-8 boundaries preserved at `finish()`. `push()` → `PushDecision`; `finish()` → `RetainedText`. |
-| `describeOmitted(omitted, unit)` | Standardized omission clause (`exact` prints a count; `unknown` does not). |
-| `formatRetentionNotice(notice, recovery)` | Joins the standardized omission clause with the tool's own recovery guidance. |
-| `Omitted` | `none` / `exact` / `unknown` — how much was omitted. |
-| `PushDecision` | `{ kept, truncated }` — the per-push retention result. |
-
-## Resource Modes
-
-The two retainers are separate names, not one generic collector, because they differ in **resource model**.
-
-- **`ItemRetainer` bounds ordered logical units.** A search tool can collect a full result set for spill-file recovery while retaining only the first `maxItems` for the model-facing preview. The omission count is exact because the caller keeps feeding every observed item.
-- **`TextRetainer` bounds byte-oriented text.** `head`, `tail`, and `headTail` preserve UTF-8 boundaries at `finish()`; `headTail` is the shape `dsh-spill-policy` uses to build a bounded preview around a spill-file notice.
-
-## `truncated` is a budget fact, never "incomplete"
-
-`truncated` means *the retainer omitted otherwise-available content because of a budget*. It does **not** mean the upstream was incomplete. Permission failures, skipped binary files, provider partial failures, unreadable candidates, and invalid UTF-8 stay in tool-domain fields — never folded into `truncated`. Conflating the two is the bug this library's naming most invites; keep them separate.
-
-## Bytes, not characters
-
-Text caps and `omittedBytes` count **bytes**, for process/body safety (a child's pipe and an HTTP body are byte streams). A chunk that straddles a codepoint is handled: `finish()` trims a partial codepoint at each cut so the returned text never introduces a replacement char at the boundary, and the two sides are decoded separately so a codepoint is never reconstructed across the omitted middle. Character- or line-level preview budgets are a separate, tool-owned concern.
-
-## Tool mappings
-
-Current retention consumers use these mappings:
-
-| Tool | Retainer & strategy | Notes |
-|---|---|---|
-| `glob` | `ItemRetainer<FsGlobEntry>`, `head` | Collect the full sorted path list for a spill file while retaining the first page inline. Path mapping, skipped candidates, and `incomplete` stay outside. |
-| `grep` | `ItemRetainer<FlatGrepMatch>`, `head` | Collect matches for a spill file while retaining the first page inline. Per-match preview truncation, grouping, sorting, and `incomplete` stay outside. |
-| `bash` | `TextRetainer`, `tail` or `headTail` | Executor still owns spill files, exit status, signal, timeout, and background jobs. |
-| `web_fetch` | `TextRetainer`, `head` or `headTail` | Provider/resource caps stay provider facts; the retainer supplies only retained text and omission metadata. |
-| `web_search` | `ItemRetainer<WebSearchSource>`, `head` | Standardizes the "sources capped" notice when providers return more sources than the model-facing result should include. |
-
-`read` remains outside this generic library. Its `read-render` helper owns a file-specific pagination contract — `offset`/`limit`, line numbers, `totalLines`, offset-out-of-range errors, per-line preview truncation, and a byte cap over the selected window — which is a line-window renderer. A single `Omitted` count cannot represent both sides of that window.
-
-## Usage shape
-
-```ts ignore-check
-// glob: keep the first page inline while still collecting the full list for spill.
-const retainer = new ItemRetainer<FsGlobEntry>({ kind: 'head', maxItems: globMaxResults })
-const allEntries: FsGlobEntry[] = []
+declare const globMaxResults: number
+declare const candidates: AsyncIterable<{ path: string }>
+const retainer = new ItemRetainer<{ path: string }>({ kind: 'head', maxItems: globMaxResults })
 for await (const entry of candidates) {
-  allEntries.push(entry)
-  retainer.push(entry)
+  retainer.push(entry)          // keep draining past the cap for an exact count
 }
 const { items, truncated, omitted } = retainer.finish()
+```
+
+`push()` reports per item whether it was kept, and `finish()` returns the retained items plus `omitted` — an exact count when the caller kept feeding every observed unit. A search tool can collect the full result set for a spill file while retaining only the first page for the model.
+
+### Bounding a text stream
+
+```text
+import { TextRetainer } from '@deepseek-ai/dsh-output-retention'
 
-// bash: keep a head + tail, read to process exit.
 const out = new TextRetainer({ kind: 'headTail', headBytes: headCap, tailBytes: tailCap })
 child.stdout.on('data', (chunk: Buffer) => { out.push(chunk) })
 const { text, omittedBytes } = out.finish()
+```
+
+`head`, `tail`, and `headTail` count bytes, not characters or lines: a child's pipe and an HTTP body are byte streams. `finish()` trims a partial codepoint at each cut, so the returned text never carries a replacement character introduced by the cut, and a codepoint is never reconstructed across the omitted middle.
+
+### Building the omission footer
+
+```ts
+import { formatRetentionNotice } from '@deepseek-ai/dsh-output-retention'
+
+declare const grepMaxMatches: number
+declare const items: { length: number }
+import type { Omitted } from '@deepseek-ai/dsh-output-retention'
+
+declare const omitted: Omitted
 
-// A footer: the library standardizes the omission clause; the tool owns recovery words.
 const footer = formatRetentionNotice(
   { scope: 'grep', strategy: 'head', unit: 'items', limit: grepMaxMatches, kept: items.length, omitted },
   ({ kept }) => `Results capped at ${kept}. Narrow the pattern, path, or include to see more.`,
 )
 ```
 
+The library standardizes the omission clause (`Omitted 3 items.`) and joins it with the tool's own recovery guidance; only the tool knows the recovery action, so the tool supplies those words.
+
+### What `truncated` means
+
+`truncated` is a budget fact: the retainer omitted otherwise-available content because of a cap. It never means the upstream was incomplete — permission failures, skipped binary files, provider partial failures, and unreadable candidates stay in tool-domain fields, never folded into `truncated`.
+
+### How the current tools use it
+
+| Tool | Retainer | What the tool still owns |
+|---|---|---|
+| `glob` | `ItemRetainer`, `head` | Spill-file collection, path mapping, skipped candidates, `incomplete` |
+| `grep` | `ItemRetainer`, `head` | Spill-file collection, per-match preview truncation, grouping, sorting |
+| `bash` | `TextRetainer`, `tail` or `headTail` | Spill files, exit status, signal, timeout, background jobs |
+| `web_fetch` | `TextRetainer`, `head` or `headTail` | Provider and resource caps, error states |
+| `web_search` | `ItemRetainer`, `head` | The "sources capped" notice wording and provider facts |
+
+`read` stays outside this library: its line-window pagination (`offset`/`limit`, line numbers, `totalLines`) is a file-specific renderer that a single omission count cannot represent.
+

+
+The library is built on one separation: it owns the mechanical question of what was kept and what was omitted; tool packages own every business meaning.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | `ItemRetainer`, `TextRetainer`, `describeOmitted`, and `formatRetentionNotice` |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; the retention algebra is exercised by unit tests) |
+
+### Two retainers, two resource models
+
+`ItemRetainer` bounds ordered logical units and keeps only the first `maxItems`; the caller keeps pushing every observed unit so the omission count is exact. `TextRetainer` bounds bytes with one shared prefix/suffix accumulator: `head` is prefix-only, `tail` is suffix-only, `headTail` is both, and the accumulator holds at most `headBytes + tailBytes + one chunk` in memory, so a large stream does not accumulate unbounded.
+
+### How the budget facts stay honest
+
+`push()` returns `kept` (this unit or chunk fully retained) and `truncated` (anything dropped yet). `finish()` reports omission against the bytes actually returned, so a UTF-8 boundary trim that drops partial-codepoint bytes is counted too — a notice built from the budget alone would overstate the retained text. `describeOmitted` prints a count only for `exact`; `unknown` prints no count because the caller provided none.
+
+### The read-render exclusion
+
+`read`'s `offset`/`limit` pagination is a line-window renderer with its own byte cap over the selected window; a single `Omitted` value cannot represent both sides of that window, so it stays out of this library.

 - **Item retention supports `head` only** — tail, head/tail, pagination, grouping, and provider-completeness semantics remain tool-owned.

-一个轻依赖的**保留**库：为必须限制返回上下文量的工具提供有界的面向模型输出。调用方将项或文本分片送入有界对象，然后取回保留的内容和精确的省略元数据。
+## 概述
 
-该库**只**负责这个机制问题：*「我们保留了什么，又省略了什么？」*。工具专用代码保留其业务语义：文件分组、行号、退出码、提供方错误状态、每行预览截断、spill 文件以及面向模型的文案。这就是 [Agent Note](../../../.agents/notes/implemented/architecture/2026-07-06-tool-result-retention-library.zh.md) 划定的边界。
+`dsh-output-retention` 限制工具返回给模型的上下文量：调用方把项或文本分片送入 retainer，然后取回保留的内容与精确的省略元数据。`ItemRetainer` 以头部预算限制有序逻辑单元列表（路径、匹配项、来源）；`TextRetainer` 以 head、tail 或 head+tail 窗口限制面向字节的文本流，并在每个切割处保持 UTF-8 边界有效。标准化的省略子句与通知格式化器让工具获得一致的「结果已达上限」页脚，而恢复指引由工具自己提供。该库只回答「保留了什么、省略了什么」这个机制问题——分组、行号、spill 文件与提供方错误状态都留在工具侧。它是轻依赖库，由工具包直接导入；`cordis.yml` 无法加载它。
 
-它是**库，而非服务或插件**：没有 `ctx`，不注册任何内容，不发出任何事件。状态只存在于每个 retainer（一次累积）中，绝不跨调用。工具包直接导入它。

+## 使用本包
+
+凡是工具必须限制其结果到达模型的数量、并如实报告丢弃内容的地方，都使用 retainer。有序逻辑单元选 `ItemRetainer`，面向字节的流选 `TextRetainer`。
+
+### 限制项列表
 
 ```ts
-import {
-  ItemRetainer, TextRetainer,
-  describeOmitted, formatRetentionNotice,
-} from '@deepseek-ai/dsh-output-retention'
-import type {
-  Omitted, PushDecision, RetainedItems, RetainedText,
-  ItemRetentionStrategy, TextRetentionStrategy, RetentionNotice,
-} from '@deepseek-ai/dsh-output-retention'
-```
+import { ItemRetainer } from '@deepseek-ai/dsh-output-retention'
 
-| 导出项 | 职责 |
-|---|---|
-| `ItemRetainer<T>` | 限制有序逻辑单元（路径、grep 匹配项、来源）。只支持 `head`。`push()` → `PushDecision`；`finish()` → `RetainedItems<T>`。 |
-| `TextRetainer` | 限制面向字节的文本流。`head` / `tail` / `headTail`，并在 `finish()` 时保留 UTF-8 边界。`push()` → `PushDecision`；`finish()` → `RetainedText`。 |
-| `describeOmitted(omitted, unit)` | 标准化的省略子句（`exact` 输出数量；`unknown` 不输出）。 |
-| `formatRetentionNotice(notice, recovery)` | 将标准化的省略子句与工具自有的恢复指引连接起来。 |
-| `Omitted` | `none` / `exact` / `unknown`：省略了多少内容。 |
-| `PushDecision` | `{ kept, truncated }`：每次 push 的保留结果。 |
-
-## 资源模式
-
-两个 retainer 使用独立名称，而不是同一个通用收集器，因为它们的**资源模型**不同。
-
-- **`ItemRetainer` 限制有序逻辑单元**。搜索工具可收集完整结果集用于 spill 文件恢复，同时只为面向模型的预览保留前 `maxItems` 项。因为调用方会继续送入每个已观察到的项，所以省略数量是精确的。
-- **`TextRetainer` 限制面向字节的文本**。`head`、`tail` 和 `headTail` 在 `finish()` 时保留 UTF-8 边界；`headTail` 是 `dsh-spill-policy` 用于围绕 spill 文件通知构建有界预览的形态。
-
-## `truncated` 是预算事实，绝不表示「不完整」
-
-`truncated` 表示*因为预算限制，retainer 省略了本可获得的内容*。它**不**表示上游不完整。权限失败、跳过二进制文件、提供方部分失败、不可读候选项和无效 UTF-8 保留在工具领域字段中，绝不合并到 `truncated`。将两者混为一谈是该库命名最容易诱发的缺陷；务必保持分离。
-
-## 字节，而非字符
-
-文本上限和 `omittedBytes` 按**字节**计数，以保证进程/正文安全（子进程管道和 HTTP 正文都是字节流）。跨越码点的分片会被正确处理：`finish()` 会修剪每个切割位置的不完整码点，使返回文本绝不在边界引入替换字符；首尾两侧会分开解码，因此绝不会跨越被省略的中间部分重建码点。按字符或行限制的预览预算属于独立的工具职责。
-
-## 工具映射
-
-当前的保留机制消费方采用以下映射：
-
-| 工具 | Retainer 与策略 | 说明 |
-|---|---|---|
-| `glob` | `ItemRetainer<FsGlobEntry>`，`head` | 收集完整的已排序路径列表用于 spill 文件，同时在内联位置保留第一页。路径映射、已跳过候选项和 `incomplete` 保留在外部。 |
-| `grep` | `ItemRetainer<FlatGrepMatch>`，`head` | 收集匹配项用于 spill 文件，同时在内联位置保留第一页。每个匹配项的预览截断、分组、排序和 `incomplete` 保留在外部。 |
-| `bash` | `TextRetainer`，`tail` 或 `headTail` | 执行器仍负责 spill 文件、退出状态、信号、超时和后台任务。 |
-| `web_fetch` | `TextRetainer`，`head` 或 `headTail` | 提供方/资源上限保留为提供方事实；retainer 只提供保留文本和省略元数据。 |
-| `web_search` | `ItemRetainer<WebSearchSource>`，`head` | 当提供方返回的来源超过面向模型的结果应包含的数量时，标准化「来源已达上限」通知。 |
-
-`read` 仍不属于这个通用库。其 `read-render` 辅助工具负责文件专用的分页约定：`offset`/`limit`、行号、`totalLines`、偏移越界错误、每行预览截断，以及所选窗口的字节上限。该辅助工具是一个行窗口渲染器。单个 `Omitted` 数量无法表示该窗口两侧。
-
-## 使用形态
-
-```ts ignore-check
-// glob: keep the first page inline while still collecting the full list for spill.
-const retainer = new ItemRetainer<FsGlobEntry>({ kind: 'head', maxItems: globMaxResults })
-const allEntries: FsGlobEntry[] = []
+declare const globMaxResults: number
+declare const candidates: AsyncIterable<{ path: string }>
+const retainer = new ItemRetainer<{ path: string }>({ kind: 'head', maxItems: globMaxResults })
 for await (const entry of candidates) {
-  allEntries.push(entry)
-  retainer.push(entry)
+  retainer.push(entry)          // keep draining past the cap for an exact count
 }
 const { items, truncated, omitted } = retainer.finish()
+```
+
+`push()` 逐项报告该项是否被保留，`finish()` 返回保留的项与 `omitted`——当调用方持续送入每个已观察单元时，这是一个精确计数。搜索工具可以收集完整结果集用于 spill 文件，同时只为模型保留第一页。
+
+### 限制文本流
+
+```text
+import { TextRetainer } from '@deepseek-ai/dsh-output-retention'
 
-// bash: keep a head + tail, read to process exit.
 const out = new TextRetainer({ kind: 'headTail', headBytes: headCap, tailBytes: tailCap })
 child.stdout.on('data', (chunk: Buffer) => { out.push(chunk) })
 const { text, omittedBytes } = out.finish()
+```
+
+`head`、`tail` 与 `headTail` 按字节而非字符或行计数：子进程管道与 HTTP 正文都是字节流。`finish()` 会在每个切割处修剪不完整的码点，因此返回的文本绝不会携带由切割引入的替换字符，码点也绝不会跨被省略的中间部分重建。
+
+### 构建省略页脚
+
+```ts
+import { formatRetentionNotice } from '@deepseek-ai/dsh-output-retention'
+
+declare const grepMaxMatches: number
+declare const items: { length: number }
+import type { Omitted } from '@deepseek-ai/dsh-output-retention'
+
+declare const omitted: Omitted
 
-// A footer: the library standardizes the omission clause; the tool owns recovery words.
 const footer = formatRetentionNotice(
   { scope: 'grep', strategy: 'head', unit: 'items', limit: grepMaxMatches, kept: items.length, omitted },
   ({ kept }) => `Results capped at ${kept}. Narrow the pattern, path, or include to see more.`,
 )
 ```
 
+库负责标准化省略子句（`Omitted 3 items.`）并把它与工具自有的恢复指引拼接；只有工具知道恢复动作，因此这些措辞由工具提供。
+
+### `truncated` 意味着什么
+
+`truncated` 是预算事实：retainer 因上限而省略了本可获得的内容。它绝不表示上游不完整——权限失败、跳过二进制文件、提供方部分失败与不可读候选项都留在工具领域字段中，绝不并入 `truncated`。
+
+### 当前工具如何使用它
+
+| 工具 | Retainer | 工具仍负责什么 |
+|---|---|---|
+| `glob` | `ItemRetainer`，`head` | spill 文件收集、路径映射、已跳过候选项、`incomplete` |
+| `grep` | `ItemRetainer`，`head` | spill 文件收集、逐匹配预览截断、分组、排序 |
+| `bash` | `TextRetainer`，`tail` 或 `headTail` | spill 文件、退出状态、信号、超时、后台任务 |
+| `web_fetch` | `TextRetainer`，`head` 或 `headTail` | 提供方与资源上限、错误状态 |
+| `web_search` | `ItemRetainer`，`head` | 「来源已达上限」通知措辞与提供方事实 |
+
+`read` 不属于本库：它的行窗口分页（`offset`/`limit`、行号、`totalLines`）是文件专属渲染器，单个省略计数无法表示该窗口的两侧。

+
+### 两个 retainer，两种资源模型
+
+`ItemRetainer` 限制有序逻辑单元，只保留前 `maxItems` 个；调用方持续送入每个已观察单元，因此省略计数是精确的。`TextRetainer` 用同一个前缀/后缀累加器限制字节：`head` 只留前缀，`tail` 只留后缀，`headTail` 两者都留；累加器在内存中至多持有 `headBytes + tailBytes + 一个分片`，因此大流不会无界累积。
+
+### 预算事实如何保持诚实
+
+`push()` 返回 `kept`（该单元或分片是否完整保留）与 `truncated`（是否已丢弃任何内容）。`finish()` 按实际返回的字节报告省略，因此丢弃部分码点字节的 UTF-8 边界修剪也会被计入——仅按预算推导的通知会高估保留文本。`describeOmitted` 只为 `exact` 打印计数；`unknown` 不打印计数，因为调用方没有提供。
+
+### read 渲染的排除
+
+`read` 的 `offset`/`limit` 分页是行窗口渲染器，对所选窗口有自己的字节上限；单个 `Omitted` 值无法表示该窗口两侧，因此它不属于本库。

-The **timing-and-classification** half of a timeout — a zero-dependency library of pure functions (no runtime harness deps) shared by every capability that clamps a caller's timeout hint, arms a deadline, and later has to tell "timed out" apart from "cancelled".
+## Summary
 
-It owns **no termination**. The signal it hands out only *notifies*; actually stopping the work stays in each capability, because that mechanism differs — bash SIGKILLs an OS process group, web tears down a `fetch` socket — and no shared layer can own all of them. This is the boundary the [Agent Note](../../../.agents/notes/implemented/architecture/2026-07-06-timeout-deadline-library.md) draws: share the timing/classification, keep the hard kill local.
+`dsh-timeout` lets a capability run one unit of work under a caller-visible timeout and later tell a timeout apart from a cancellation. A caller's optional hint is clamped against a backend default and cap, and upstream cancellation fuses with the deadline into one `AbortSignal`. The deadline signal only notifies — each capability owns the mechanism that stops its work, so no shared layer needs to know how to stop anything. For streamed transports an idle watchdog arms a timeout only while a provider read is outstanding, so consumer think time never counts as idle. A `timeoutMs` of zero is the internal no-timeout sentinel for backend-owned background work, never a public disable switch; the zero-dependency library is shared by the bash, web, subprocess, and tool-timeout-policy consumers.
 
-It is a **library, not a service or plugin**: no `ctx`, registers nothing, holds no state, emits no events. A "timeout service" would have to understand how to stop every capability's work — exactly the knowledge a microkernel keeps out of shared layers.

+## Use this package
+
+Use `deadline` when a capability runs one unit of work under a caller-visible timeout, and `idleWatchdog` when it reads a streamed transport. Validate caller hints with `clampTimeout` first so the `timeoutMs` that reaches `deadline` is always positive and finite.
+
+### Clamping a timeout hint
 
 ```ts
-import { clampTimeout, deadline, idleWatchdog, MAX_TIMER_DELAY_MS, timeoutOf, TimeoutReason } from '@deepseek-ai/dsh-timeout'
+import { clampTimeout } from '@deepseek-ai/dsh-timeout'
+
+declare const requested: number | undefined
+declare const DEFAULT_TIMEOUT_MS: number
+declare const MAX_TIMEOUT_MS: number
+
+const timeoutMs = clampTimeout(requested, DEFAULT_TIMEOUT_MS, MAX_TIMEOUT_MS, 'bash-local: request.timeoutMs')
 ```
 
-| Export | Role |
-|---|---|
-| `clampTimeout(requested, def, max, name?)` | Validate the caller's optional positive-finite hint, fill from `def`, cap at `max`. Throws (with `name`) on a non-positive/non-finite hint. |
-| `deadline(upstream, timeoutMs, code)` | Fuse `upstream` cancellation with a timeout into one `AbortSignal` (`AbortSignal.any`); the timeout carries a `TimeoutReason`. `[Symbol.dispose]` clears the timer. |
-| `idleWatchdog(upstream, timeoutMs, code)` | Keep one stable fused signal and arm only while its guarded async-iterator `next()` is outstanding. Resolution disarms; later demand or `pulse()` activity rearms; disposal clears; concurrent demand rejects. |
-| `MAX_TIMER_DELAY_MS` | Largest delay Node schedules without clamping it to one millisecond (`2_147_483_647`). Timer-owning config must not exceed it. |
-| `timeoutOf(signal \| { reason }, code?)` | Recover the `TimeoutReason` from an aborted signal/error, else `undefined` — the timeout-vs-cancel classifier. Pass `code` to match only THIS deadline's timer (see nesting below). |
-| `TimeoutReason` | The internal reason (`code` + `timeoutMs`) stamped on a timeout abort. Not a public error — providers translate it into their own error/field. |
+`clampTimeout` fills the backend default when the hint is absent, caps the result at the backend maximum, and rejects a non-positive or non-finite hint with the caller-provided name. Zero is never accepted here: it is not a public disable-timeout value.
 
-## The `timeoutMs <= 0` sentinel
+### Running work under a deadline
 
-`0` is the **internal** "no timeout" value for backend-owned background work (bash `start()`): `deadline()` arms no timer and forwards only `upstream`; with no upstream either, it returns a never-aborting signal plus a no-op disposer, so every caller keeps one call shape. External request hints validate as **positive finite** via `clampTimeout` before they reach `deadline`, so `0` is never a model-/plugin-facing "disable timeout" value.
-
-## Usage shape
-
-```ts
+```text
 import { deadline, timeoutOf } from '@deepseek-ai/dsh-timeout'
 
-declare function runWork(options: { signal: AbortSignal }): Promise<unknown>
-
-// Scope-lifetime consumer (foreground bash, one fetch): `using` disposes the timer.
-export async function runWithDeadline(upstream: AbortSignal | undefined, timeoutMs: number): Promise<unknown> {
-  using d = deadline(upstream, timeoutMs, 'BASH_TIMEOUT')
-  const outcome = await runWork({ signal: d.signal })               // work listens on d.signal and terminates itself
-  const timedOut = timeoutOf(d.signal, 'BASH_TIMEOUT') !== undefined // classify the first abort, scoped to OUR code
-  const aborted = d.signal.aborted && !timedOut                     // mutually exclusive: timeout won, or cancel did
-  return { outcome, timedOut, aborted }
-}
+using d = deadline(upstream, timeoutMs, 'BASH_TIMEOUT')
+const outcome = await runWork({ signal: d.signal })   // work listens on d.signal and terminates itself
+const timedOut = timeoutOf(d.signal, 'BASH_TIMEOUT') !== undefined
+const aborted = d.signal.aborted && !timedOut
 ```
 
-The signal only *notifies* — the caller MUST attach its own termination (`d.signal.addEventListener('abort', kill)`, or hand `d.signal` to `fetch`). Racing a promise against a timer would resolve the tool-call while the child process or socket leaks on; handing out a signal forces a real termination path to exist.
+The signal only notifies: the caller must attach its own termination — hand `d.signal` to `fetch`, or listen for `abort` and kill the child. Racing a promise against a timer would resolve the tool call while the child process or socket leaks on.
 
-Pass your own `code` to `timeoutOf` so classification composes under nesting. When `upstream` is itself a deadline signal, `AbortSignal.any` preserves its `TimeoutReason` if that timer fires first. Scoping to your code makes a foreign timeout read as an ordinary upstream cancel instead of claiming that the local timer expired.
+### Classifying the outcome
 
-For a streamed transport, create one `idleWatchdog`, pass its stable `signal` into the transport, and call `watchdog.next(iterator)` for each provider read. Call `watchdog.pulse()` when transport activity does not yield an iterator value. The interval must be positive, finite, and no greater than `MAX_TIMER_DELAY_MS`; Node otherwise clamps it to one millisecond. It measures only outstanding demand, so no timer runs while downstream code renders or otherwise waits before asking for the next chunk. The primitive still only notifies, so the transport must observe the stable signal; the DeepSeek and pi-ai adapters prove that timeout closes their real response body or SDK request.
+`timeoutOf(signal, code)` recovers the timeout reason only when this deadline's timer fired first. Pass your own `code` so classification composes under nesting: when `upstream` is itself a deadline signal, a foreign timeout reads as an ordinary upstream cancellation instead of claiming that the local timer expired.
 
-## What does NOT get a timeout
+### Streaming with an idle watchdog
 
-Local file `read`/`write`/`edit` take no `timeoutMs`: file IO runs untimed because a deadline would kill work the OS will still finish. See [the filesystem subsystem page](../../../docs/subsystems/filesystem.md).
+```ts
+import { idleWatchdog } from '@deepseek-ai/dsh-timeout'
 
+declare const upstream: AbortSignal | undefined
+declare const idleMs: number
+declare const providerIterator: AsyncIterator<unknown>
+
+using watchdog = idleWatchdog(upstream, idleMs, 'LLM_STREAM_IDLE_TIMEOUT')
+const next = await watchdog.next(providerIterator)    // timer runs only while this read is outstanding
+```
+
+The timer is armed only while an iterator `next()` is outstanding and rearms on `pulse()` for transport activity that yields no value, so consumer think time between reads never counts as idle. The interval must be positive, finite, and no greater than `MAX_TIMER_DELAY_MS`.
+
+### What does not get a timeout

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+The library is built on one boundary: share the timing and classification, keep the hard kill local.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | `clampTimeout`, `deadline`, `idleWatchdog`, `timeoutOf`, `TimeoutReason`, `MAX_TIMER_DELAY_MS` |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; the timing algebra is exercised by unit tests) |
+
+### How a deadline fuses sources
+
+`deadline` arms one timer and fuses its abort with the upstream signal via `AbortSignal.any`, which adopts the reason of whichever source aborts first — so a race resolves to a single cause. The `TimeoutReason` carries the capability-owned `code` and the elapsed `timeoutMs`; `timeoutOf` reads it only when the timeout won, and upstream-wins leaves an ordinary abort reason. `[Symbol.dispose]` clears the timer.
+
+### The no-timeout sentinel
+
+`timeoutMs <= 0` arms no timer and forwards only the upstream signal — or a never-aborting signal when there is none — so every caller keeps one call shape. The sentinel exists for backend-owned background work; external request hints are validated positive and finite before they reach `deadline`.
+
+### Why an idle watchdog rearms
+
+`idleWatchdog` keeps one stable fused signal and arms the timer only while `next()` is outstanding; resolution disarms, later demand or `pulse()` rearms, disposal clears, and concurrent demand rejects. Only the transport observes the signal, so the provider's real read must listen to it — the DeepSeek and pi-ai adapters close their response body or SDK request on abort.

 ## Known Limitations and Deferred Work
 
-- **Notification only** — a deadline cannot stop work that ignores its signal; every capability still needs its own socket/process/task termination path.
-- **`timeoutMs <= 0` is internal vocabulary** — it disables the local timer only after an owning backend has resolved policy, never as a public model/plugin knob.

-超时的**时序与分类**部分：一个零依赖纯函数库（无运行时 harness 依赖），由每个需要限制调用方超时提示、启动 deadline，并在之后区分「已超时」与「已取消」的能力共享。
+## 概述
 
-它**不负责终止**。它发出的信号只会*通知*；真正停止工作仍由各能力负责，因为机制各不相同：bash 对操作系统进程组发送 SIGKILL，web 关闭 `fetch` 套接字，没有任何共享层能够承担全部终止机制。[Agent Note](../../../.agents/notes/implemented/architecture/2026-07-06-timeout-deadline-library.zh.md) 将边界划定为：共享时序/分类，将强制终止保留在本地。
+`dsh-timeout` 让能力在调用方可见的超时下运行一个工作单元，之后能把超时与取消区分开。调用方的可选提示会按后端默认值补齐、并按后端上限封顶，上游取消与截止时间融合为一个 `AbortSignal`。deadline 信号只负责通知——停止工作的机制由各能力自己拥有，因此没有任何共享层需要知道如何停止任何东西。对于流式传输，空闲 watchdog 只在提供方读取尚未完成时启动超时，因此消费方的思考时间绝不计入空闲。`timeoutMs` 为 0 是后端自有后台工作使用的内部「无超时」哨兵值，绝不是公开的禁用开关；这个零依赖库由 bash、web、subprocess 与 tool-timeout-policy 消费方共享。
 
-它是**库，而非服务或插件**：没有 `ctx`，不注册任何内容，不持有状态，也不发出事件。「超时服务」必须了解如何停止每项能力的工作，这正是微内核要排除在共享层之外的知识。

+## 使用本包
+
+当能力要在调用方可见的超时下运行一个工作单元时使用 `deadline`，读取流式传输时使用 `idleWatchdog`。先用 `clampTimeout` 验证调用方提示，确保到达 `deadline` 的 `timeoutMs` 总是正有限值。
+
+### 限制超时提示
 
 ```ts
-import { clampTimeout, deadline, idleWatchdog, MAX_TIMER_DELAY_MS, timeoutOf, TimeoutReason } from '@deepseek-ai/dsh-timeout'
+import { clampTimeout } from '@deepseek-ai/dsh-timeout'
+
+declare const requested: number | undefined
+declare const DEFAULT_TIMEOUT_MS: number
+declare const MAX_TIMEOUT_MS: number
+
+const timeoutMs = clampTimeout(requested, DEFAULT_TIMEOUT_MS, MAX_TIMEOUT_MS, 'bash-local: request.timeoutMs')
 ```
 
-| 导出项 | 职责 |
-|---|---|
-| `clampTimeout(requested, def, max, name?)` | 验证调用方可选的、值为正且有限的提示，从 `def` 填充，并限制在 `max` 以内。如果提示为非正数或非有限数，则抛出错误（包含 `name`）。 |
-| `deadline(upstream, timeoutMs, code)` | 将 `upstream` 取消与超时融合为一个 `AbortSignal`（`AbortSignal.any`）；超时携带 `TimeoutReason`。`[Symbol.dispose]` 清除 timer。 |
-| `idleWatchdog(upstream, timeoutMs, code)` | 保持一个稳定的融合信号，并且只在受保护的异步迭代器 `next()` 尚未完成时启动 timer。完成后停止 timer；后续需求或 `pulse()` 活动会重新启动 timer；dispose（资源释放）时清除；并发需求被拒绝。 |
-| `MAX_TIMER_DELAY_MS` | Node 在不将延迟限制为 1 毫秒时可调度的最大延迟（`2_147_483_647`）。负责 timer 的配置不得超过该值。 |
-| `timeoutOf(signal \| { reason }, code?)` | 从已中止的信号/错误中恢复 `TimeoutReason`，否则返回 `undefined`，即超时与取消的分类器。传入 `code` 可仅匹配这个 deadline 的 timer（见下文的嵌套）。 |
-| `TimeoutReason` | 标记在超时中止上的内部原因（`code` + `timeoutMs`）。它不是公开错误；提供方将其转换为自己的错误/字段。 |
+提示缺失时 `clampTimeout` 填入后端默认值，把结果限制在后端最大值以内，并以调用方提供的名字拒绝非正数或非有限值的提示。此处绝不接受 0：它不是公开的禁用超时值。
 
-## `timeoutMs <= 0` 哨兵值
+### 在 deadline 下运行工作
 
-`0` 是后端自有后台工作（bash `start()`）使用的**内部**「无超时」值。`deadline()` 不启动 timer，只转发 `upstream`；如果也没有 upstream，它将返回永不中止的信号和无操作 disposer，因此每个调用方都能保持同一种调用形态。外部请求提示会通过 `clampTimeout` 验证为**正有限数**，之后才进入 `deadline`，因此 `0` 绝不是面向模型/插件的「禁用超时」值。
-
-## 使用形态
-
-```ts
+```text
 import { deadline, timeoutOf } from '@deepseek-ai/dsh-timeout'
 
-declare function runWork(options: { signal: AbortSignal }): Promise<unknown>
-
-// Scope-lifetime consumer (foreground bash, one fetch): `using` disposes the timer.
-export async function runWithDeadline(upstream: AbortSignal | undefined, timeoutMs: number): Promise<unknown> {
-  using d = deadline(upstream, timeoutMs, 'BASH_TIMEOUT')
-  const outcome = await runWork({ signal: d.signal })               // work listens on d.signal and terminates itself
-  const timedOut = timeoutOf(d.signal, 'BASH_TIMEOUT') !== undefined // classify the first abort, scoped to OUR code
-  const aborted = d.signal.aborted && !timedOut                     // mutually exclusive: timeout won, or cancel did
-  return { outcome, timedOut, aborted }
-}
+using d = deadline(upstream, timeoutMs, 'BASH_TIMEOUT')
+const outcome = await runWork({ signal: d.signal })   // work listens on d.signal and terminates itself
+const timedOut = timeoutOf(d.signal, 'BASH_TIMEOUT') !== undefined
+const aborted = d.signal.aborted && !timedOut
 ```
 
-该信号只会*通知*；调用方必须接入自己的终止机制（`d.signal.addEventListener('abort', kill)`，或将 `d.signal` 传给 `fetch`）。让 promise 与 timer 竞速，会在子进程或套接字仍在泄漏时就让工具调用完成；发出信号则会强制要求存在真正的终止路径。
+该信号只负责通知：调用方必须接入自己的终止机制——把 `d.signal` 传给 `fetch`，或监听 `abort` 并杀死子进程。让 promise 与 timer 竞速，会在子进程或套接字仍在泄漏时就让工具调用完成。
 
-将你自己的 `code` 传给 `timeoutOf`，使分类可在嵌套场景中正确组合。当 `upstream` 本身是 deadline 信号时，如果该 timer 先触发，`AbortSignal.any` 会保留它的 `TimeoutReason`。将匹配范围限定为你的 code，会把外部超时视为普通的 upstream 取消，而不会声称本地 timer 已到期。
+### 分类结果
 
-对于流式传输，创建一个 `idleWatchdog`，将其稳定的 `signal` 传给传输层，并为提供方的每次读取调用 `watchdog.next(iterator)`。当传输活动不产生迭代器值时，调用 `watchdog.pulse()`。间隔必须为正有限数，且不得超过 `MAX_TIMER_DELAY_MS`；否则 Node 会将其限制为 1 毫秒。它只对尚未完成的读取请求计时，因此当下游代码进行渲染或在请求下一个分片前以其他方式等待时，timer 不会运行。该原语仍然只会通知，因此传输层必须观察稳定信号；DeepSeek 和 pi-ai 适配器证明，超时会关闭它们的真实响应正文或 SDK 请求。
+只有当本 deadline 的 timer 先触发时，`timeoutOf(signal, code)` 才恢复超时原因。传入你自己的 `code`，让分类在嵌套场景中正确组合：当 `upstream` 本身是 deadline 信号时，外部超时会被当作普通的上游取消，而不是声称本地 timer 已到期。
 
-## 哪些操作不设置超时
+### 用空闲 watchdog 处理流式传输
 
-本地文件 `read`/`write`/`edit` 不接受 `timeoutMs`：文件 IO 不设时限地运行，因为截止时间会中止操作系统仍会完成的工作。详见[文件系统子系统页面](../../../docs/subsystems/filesystem.zh.md)。
+```ts
+import { idleWatchdog } from '@deepseek-ai/dsh-timeout'
 
+declare const upstream: AbortSignal | undefined
+declare const idleMs: number
+declare const providerIterator: AsyncIterator<unknown>
+
+using watchdog = idleWatchdog(upstream, idleMs, 'LLM_STREAM_IDLE_TIMEOUT')
+const next = await watchdog.next(providerIterator)    // timer runs only while this read is outstanding
+```
+
+timer 只在某个迭代器 `next()` 尚未完成时启动，并会因不产生值的传输活动通过 `pulse()` 重新启动，因此读取之间的消费方思考时间绝不计入空闲。间隔必须为正有限数，且不得大于 `MAX_TIMER_DELAY_MS`。

+### deadline 如何融合来源
+
+`deadline` 启动一个 timer，并通过 `AbortSignal.any` 把它与上游信号融合；`AbortSignal.any` 采纳最先中止的来源的原因，因此竞争会归结为单一原因。`TimeoutReason` 携带能力自有的 `code` 与已流逝的 `timeoutMs`；只有当超时胜出时 `timeoutOf` 才读取它，上游胜出则保留普通的中止原因。`[Symbol.dispose]` 清除 timer。
+
+### 无超时哨兵值
+
+`timeoutMs <= 0` 不启动 timer，只转发上游信号——没有上游时返回永不中止的信号——因此每个调用方都保持同一种调用形态。该哨兵值服务于后端自有后台工作；外部请求提示在到达 `deadline` 之前先被验证为正有限值。
+
+### 空闲 watchdog 为何重新启动
+
+`idleWatchdog` 保持一个稳定的融合信号，只在 `next()` 尚未完成时启动 timer；完成后停止，后续需求或 `pulse()` 重新启动，dispose（资源释放）时清除，并发需求被拒绝。只有传输层观察该信号，因此提供方的真实读取必须监听它——DeepSeek 与 pi-ai 适配器会在中止时关闭响应正文或 SDK 请求。

+
 - **Resolution is lexical** — it recognizes POSIX absolute paths, Windows drive paths, and UNC paths but does not access a filesystem or canonicalize `.` and `..` segments.
 - **Home abbreviation is POSIX-only** — Windows paths remain unchanged because a portable browser cannot infer Windows home-path equivalence safely.

+# web/ — web access capability family
 
 English | [中文](README.zh.md)
 
-This family provides provider-neutral web search and fetch operations plus the model-facing tools that consume them.
+## Summary
+
+The `web/` group gives the harness web access — searching the web and fetching URLs — through one provider-neutral service (`ctx.web`) and the backends and tools that use it. A deployment mounts one or more backends — Exa, Perplexity, or DeepSeek for search, anonymous HTTP(S) for fetch — and the service picks a usable provider per operation, so the model-facing tools stay stable while backends come and go. Six packages split the family: the `web/` service that owns provider selection and errors, three search backends, one fetch backend, and `tool-web/`, which exposes `web_search` and `web_fetch` to the model. The group owns web access only: no browsing or extraction, no per-URL policy, and each backend keeps its own resource caps. Search and fetch deliberately share one service so selection, cancellation, errors, and configuration have a single owner.

-| [`tool-web/`](tool-web/README.md) | Exposes web search and fetch to the model | registers on `ctx.tools` |
+| [`web/`](web/README.md) | Search/fetch service: search and fetch URLs through interchangeable backends, one selection and error policy | `ctx.web` |

-| 包 | 职责 | ctx key |
+`web/` 组为 harness 提供 web 访问能力——搜索 web 与抓取 URL——通过一个与提供方无关的服务（`ctx.web`）以及使用它的后端和工具。部署可以挂载一个或多个后端——搜索用 Exa、Perplexity 或 DeepSeek，抓取用匿名 HTTP(S)——服务按操作挑选可用的提供方，因此后端来来去去，面向模型的工具保持稳定。六个包构成该家族：负责提供方选择与错误的 `web/` 服务、三个搜索后端、一个抓取后端，以及向模型公开 `web_search` 与 `web_fetch` 的 `tool-web/`。该组只拥有 web 访问本身：没有浏览或提取，没有逐 URL 策略，各后端保留自己的资源上限。搜索与抓取有意共用一项服务，使选择、取消、错误与配置只有一个归属方。

 English | [中文](README.zh.md)
 
-The model-facing web tool suite — `web_search` and `web_fetch` — over the [web capability seam](../web/README.md) (`ctx.web`). It owns model-facing concerns only: tool names, JSON schemas, snake_case argument names, prompt sections, the result-count bound, result formatting, HTML→markdown presentation, and the UI presentation projection — `presentCall`, `presentResult` (a `card: 'web'` result card discriminated by `kind: 'search' | 'fetch'`), and the `output.presentationMeta` that carries the structured search sources or the fetch summary the lossy render text cannot (see the [web-result-card Agent Note](../../../.agents/notes/implemented/feature/2026-07-30-web-result-card.md)). Every successful result labels provider-controlled text as external and untrusted; HTML conversion removes active and hidden elements before model presentation. All web access goes through `ctx.web`; this package never imports a concrete provider. Neither tool exposes a model-facing timeout — each tool's cooperative tool-call budget is declared here via config (`fetchTimeoutMs`/`searchTimeoutMs`, attached as `ToolDefinition.timeoutMs`) and enforced by [`@deepseek-ai/dsh-tool-call-timeout-policy`](../../guard/timeout-policy/README.md) (a `tools/execute` wrapper). Single operations forward `exec.signal`; a multi-query search fuses it with batch cancellation so a failed query aborts its siblings.
+## Summary
 
-Each tool is registered independently; a product that wants only one disables the other via config (`{ search: false }` / `{ fetch: false }`). Search guidance mentions `web_fetch` only when fetch is also config-enabled; a search-only composition instead tells the model to use returned snippets and cite their URLs.
+With `dsh-tool-web`, the model can search the web and fetch pages through the `web_search` and `web_fetch` tools, backed by the harness web service (`ctx.web`). Choose it when the model should search the web or fetch pages; the two tools register independently, so a product disables either via config. Every successful result labels provider-controlled text as external and untrusted, and HTML conversion removes active or hidden content. Tools stay visible even when their selected provider is missing or unavailable: execution then fails with a structured error the model can read. Neither tool exposes a model-facing timeout; per-tool budgets are deployment config enforced by the timeout policy.
 
-## Tools
+## Table of Contents
 
-| Tool | Args | Behavior |
-|---|---|---|
-| `web_search` | `queries` (required string[]) | Discovery. Returns an optional answer plus source URLs. It runs one to `searchMaxQueries` distinct searches concurrently and merges their sources in round-robin order before applying the combined `searchMaxResults` cap. A one-item array performs one search. Exact duplicate queries run once. Any failed search aborts the remaining batch, which settles before the call returns an error. Neither bound is model-facing. |
-| `web_fetch` | `url` (string) | Retrieves a specific URL. HTML bodies are filtered and rendered to markdown (turndown with GFM tables/strikethrough); text bodies pass through under an untrusted-content notice. A non-2xx status is reported, not an error. The tool-call timeout is deployment policy (`dsh-tool-call-timeout-policy`), not a model argument. |

-Both tools opt into concurrent scheduling because provider reads return content without mutating parent-agent state.
+-----
 
-The normalized service results are also the canonical tool values: `WebSearchResult` and `WebFetchResult`. Native renderers preserve the answer/source and fetched-body text below; provider search/body caps remain acquisition limits rather than presentation-only truncation.
+<a id="use-this-package"></a>
+## Use this package
 
-## Config
+Load the package in a composition that already mounts the web service and at least one search or fetch backend; it adds `web_search` and `web_fetch` to the model's toolset and their guidance to the system prompt.
 
-| Key | Default | Meaning |
-|---|---|---|
-| `search` | `true` | Register `web_search`. |
-| `fetch` | `true` | Register `web_fetch`. |
-| `searchMaxResults` | `8` | Upper bound on sources returned by one `web_search` call (the seam truncates each provider list; the tool also caps a combined multi-query list). |
-| `searchMaxQueries` | `4` | Upper bound on queries accepted by one `web_search` call. The configured value appears in its prompt guidance and schema descriptions. |
-| `fetchTimeoutMs` | `30000` | Cooperative tool-call timeout budget (ms) for `web_fetch`. |
-| `searchTimeoutMs` | `30000` | Cooperative tool-call timeout budget (ms) for `web_search`. |
-| `fetchMaxOutputChars` | `200000` | Cap on source characters converted synchronously and on one complete `web_fetch` output (header, rendered body, and footer); a cut body gets the truncation notice when it fits. |
+### When to choose it
 
-`searchMaxQueries` bounds the accepted array before exact-string deduplication, provider fan-out, and combined provider-answer growth; validation rejects an oversized array before any search starts, then dispatch keeps the first occurrence of each query. Together with each provider's own controls such as `maxUses`, these independent settings are the product's search budgets; the generic seam does not expose provider-internal native-search accounting. `fetchTimeoutMs`/`searchTimeoutMs` declare each tool's cooperative timeout budget (attached as `ToolDefinition.timeoutMs`), enforced by [`@deepseek-ai/dsh-tool-call-timeout-policy`](../../guard/timeout-policy/README.md); the model-facing schema exposes no timeout argument. `fetchMaxOutputChars` bounds both synchronous conversion work and the complete rendered result: only that many source characters are converted, and the header, converted prefix, and truncation notice are then capped together. The default leaves headroom above the local provider's 100,000-character body cap, but rendered expansion can still make the final bound truncate the result.
+Choose this package when the model should discover current information or read a specific page: `web_search` returns an optional answer plus source URLs, and `web_fetch` retrieves a page's content as text. A product that wants only one tool disables the other via config (`{ search: false }` or `{ fetch: false }`); search guidance mentions `web_fetch` only when fetch is also enabled, and a search-only composition instead tells the model to use returned snippets and cite their URLs.
+
+### Minimal configuration
+
+Load the web service, at least one backend, and this package; both tools register by default.
 
 ```yaml
-- id: tool-web
-  name: '@deepseek-ai/dsh-tool-web'

 ```
 
-## Stable registration
+| Field | Default | Meaning |
+|---|---|---|
+| `search` | `true` | Register `web_search` |
+| `fetch` | `true` | Register `web_fetch` |
+| `searchMaxResults` | `8` | Upper bound on sources returned by one `web_search` call |
+| `searchMaxQueries` | `4` | Upper bound on queries accepted by one `web_search` call; the value appears in prompt guidance and schema descriptions |
+| `fetchTimeoutMs` | `30000` | Cooperative tool-call timeout budget (ms) for `web_fetch` |
+| `searchTimeoutMs` | `30000` | Cooperative tool-call timeout budget (ms) for `web_search` |
+| `fetchMaxOutputChars` | `200000` | Cap on source characters converted synchronously and on one complete `web_fetch` output |
 
-Tool registration follows product **enablement**, not backend availability. A tool stays visible even when its selected provider is missing, misconfigured, ambiguous, or temporarily unavailable; the seam resolves the provider at execution time and execution fails with a structured `WebError` (e.g. `WEB_PROVIDER_UNAVAILABLE`, `WEB_PROVIDER_AMBIGUOUS`), which `ToolRuntime.execute()` turns into an error tool result the model can read and hooks/UI can route on. This keeps the model schema stable without making plugin load order, credential state, or HMR timing part of the model-facing contract. To remove a web tool entirely, disable it here in config.
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-tool-web) is the exhaustive source for every accepted field and its JSDoc. `searchMaxQueries` bounds the accepted array before exact-string deduplication and provider fan-out; validation rejects an oversized array before any search starts. The timeout budgets attach to each tool definition and are enforced by [`@deepseek-ai/dsh-tool-call-timeout-policy`](../../guard/timeout-policy/README.md); the model-facing schemas expose no timeout argument.
 
-The tool never calls a provider's `available()` and never enumerates providers — its only execution path is `ctx.web.search()` / `ctx.web.fetch()`, and provider unavailability reaches it as the structured `WebError` codes selection throws at execution time. Provider selection stays entirely inside the seam, with one owner.
+### Using web_search
 
+Call `web_search` with a `queries` array of one to `searchMaxQueries` non-empty strings. Exact duplicate queries run once; multiple queries run concurrently and their sources merge round-robin before the combined `searchMaxResults` cap applies. The result is an optional provider answer followed by `Sources:` with one line per source — `- [<title-or-url>](<url>)`, optionally with snippet and date — and a standing instruction to cite the URLs.
+
+```text
+web_search({ queries: ['deepseek harness documentation'] })
+```
+
+If any query in a multi-query call fails, `web_search` aborts the remaining searches, waits for every started search to settle, discards successful results, and returns `Error: <message>` for the first failure.
+
+### Using web_fetch
+
+Call `web_fetch` with one `url`. HTML bodies are filtered and rendered to markdown (GFM tables and strikethrough included); text bodies pass through under an untrusted-content notice. A non-2xx status is reported in the result, not thrown as an error. Truncated content appends `(Content truncated. Fetch a more specific URL or section for the full text.)`.
+
+```text
+web_fetch({ url: 'https://example.com' })
+```
+
+### Stable registration
+
+Tool registration follows product enablement, not backend availability: a tool stays visible even when its selected provider is missing, misconfigured, ambiguous, or temporarily unavailable. Execution then fails with a structured `WebError` — for example `WEB_PROVIDER_UNAVAILABLE` or `WEB_PROVIDER_AMBIGUOUS` — which becomes an error tool result the model can read and hooks or UI can route on. To remove a web tool, disable it here in config.
+
+### Failures and recovery
+
+Schema validation rejects an absent or non-array `queries` field, non-string array elements, an oversized array, or a blank URL before execution, with exact messages such as `Error: queries must contain at least one query` and `Error: url must be a non-empty string`. Provider-side failures surface as structured error tool results; the model can read them and decide the next step, for example fetching a cited URL or refining a query.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the tools; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The package is built on one separation and one registration rule:
+
+- **The consumer owns the model-facing contract.** Tool names, schemas, snake_case argument names, prompt sections, result bounds, formatting, and presentation all live here; provider selection stays entirely inside `ctx.web`. The tools never call a provider's `available()` and never enumerate providers — their only execution path is `ctx.web.search()` / `ctx.web.fetch()`.
+- **Enablement drives registration.** A tool registers when enabled in config, independent of backend availability, so plugin load order, credential state, and HMR timing never enter the model-facing contract.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: config schema, enablement, timeout budgets, tool registration |
+| [`src/search.ts`](src/search.ts) | The `web_search` tool: argument validation, query fan-out, merge, formatting, presentation meta |
+| [`src/fetch.ts`](src/fetch.ts) | The `web_fetch` tool: HTML→markdown conversion, output caps, formatting, presentation meta |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; contracts are enforced at the tools) |
+
+### Search flow
+
+`web_search` validates the arguments (non-empty array, count bound, non-blank strings), collapses exact duplicates to first occurrence, then runs one to `searchMaxQueries` distinct searches concurrently through `ctx.web`. A failure aborts the batch via a fused signal; the call waits for every started search to settle before returning the first failure. Successful results merge round-robin by rank, deduplicate by URL, cap at `searchMaxResults`, and format into the model-facing text.
+
+### Fetch flow
+
+`web_fetch` removes active and hidden HTML before a shared turndown converter renders GFM tables and strikethrough. A lexical nesting guard and conversion failures produce a fixed omission marker instead of returning unsafe raw HTML, and a synchronous conversion cap bounds DOM work. The complete output — header, untrusted-content notice, rendered body, and truncation footer — is then bounded as a whole. Conversion is memoized per result and cap so registry render and presentation share one parse.
+
+### Presentation
+
+Each tool attaches structured metadata to its result (`output.presentationMeta`) — the faithful search sources, or the fetch summary (final URL, status code, effective truncation) — so the UI can render `web` result cards and replay reproduces them without reparsing the lossy render text. A UI without the `web` capability falls back to the raw tool result, which is the same text.

 ## Known Limitations and Deferred Work
 
-- **There is no batch-wide native-search counter** — `searchMaxQueries` bounds `ctx.web.search` calls, but a provider may perform several native searches inside each call. For example, a model-backed provider configured with `maxUses` can permit up to `searchMaxQueries × maxUses` native searches; `searchMaxResults` limits only the combined sources returned to the caller. Deployments control cost through these independent consumer and provider settings because the generic seam does not know provider-internal search units.
-- **HTML→markdown conversion omits inputs it cannot safely represent** — [turndown](https://github.com/mixmark-io/turndown) (with GFM tables/strikethrough) converts at most `fetchMaxOutputChars` source characters through a real DOM. A conservative 512-level lexical guard and conversion exceptions produce a fixed omission marker rather than raw HTML, and table `colspan` is ignored because GFM has no spanning-cell representation; these bounds avoid blocking the event loop or expanding output from an untrusted numeric attribute ([archived dependency decision](../../../.agents/notes/archived/simplification/2026-07-26-turndown-for-tool-web-html-markdown.md)).

 [English](README.md) | 中文
 
-面向模型的 web 工具套件 `web_search` 与 `web_fetch`，构建于 [web 能力 seam](../web/README.zh.md)（`ctx.web`）之上。它只负责面向模型的事项：工具名称、JSON Schema、snake_case 参数名称、提示词区段、结果数量上限、结果格式、HTML→markdown 呈现，以及 UI 呈现投影——`presentCall`、`presentResult`（以 `kind: 'search' | 'fetch'` 区分的 `card: 'web'` 结果卡片），以及承载有损渲染文本无法携带的结构化搜索来源或抓取摘要的 `output.presentationMeta`（见 [web-result-card Agent Note](../../../.agents/notes/implemented/feature/2026-07-30-web-result-card.zh.md)）。每个成功结果都会把提供方控制的文本标记为外部不可信数据；HTML 转换会在向模型展示前移除主动内容和隐藏元素。所有 web 访问都通过 `ctx.web`；该包绝不导入具体提供方。两个工具都不公开面向模型的超时：每个工具的协作式工具调用超时预算通过配置在此声明（`fetchTimeoutMs`／`searchTimeoutMs`，附加为 `ToolDefinition.timeoutMs`），由 [`@deepseek-ai/dsh-tool-call-timeout-policy`](../../guard/timeout-policy/README.zh.md)（`tools/execute` 包装层）强制执行。单项操作会转发 `exec.signal`；多查询搜索会把它与批次取消信号融合，使失败查询能够中止其余查询。
+## 概述
 
-每个工具独立注册；只需要其中一个工具的产品可以通过配置禁用另一个（`{ search: false }`／`{ fetch: false }`）。仅当抓取也通过配置启用时，搜索指引才会提及 `web_fetch`；仅启用搜索的组合则会要求模型使用返回的 snippet 并引用其 URL。
+有了 `dsh-tool-web`，模型可以通过 `web_search` 与 `web_fetch` 工具搜索 web 或抓取页面，二者构建于 harness web 服务（`ctx.web`）之上。当模型需要搜索 web 或抓取页面时选择它；两个工具独立注册，因此产品可以通过配置禁用任一工具。每个成功结果都把提供方控制的文本标记为外部不可信数据，HTML 转换会删除活动或隐藏内容。即使选中的提供方缺失或不可用，工具仍保持可见：执行随后以模型可读的结构化错误失败。两个工具都不公开面向模型的超时；每个工具预算都是部署配置，由超时策略强制执行。
 
-## 工具
+## 目录
 
-| 工具 | 参数 | 行为 |
-|---|---|---|
-| `web_search` | `queries`（必填 string[]） | 用于发现信息。返回可选答案与来源 URL。它会并发执行 1 至 `searchMaxQueries` 个不同搜索，按轮询顺序合并来源，再应用组合后的 `searchMaxResults` 上限。单元素数组执行一次搜索。完全相同的查询只执行一次。任何搜索失败都会中止批次中的其余搜索；批次结算完毕后调用才返回错误。两个上限都不面向模型。 |
-| `web_fetch` | `url`（string） | 获取特定 URL。HTML 主体经过过滤后渲染为 markdown（turndown，带 GFM 表格／删除线）；文本主体在不可信内容提示后原样通过。非 2xx 状态会报告，而非报错。工具调用超时是部署策略（`dsh-tool-call-timeout-policy`），不是模型参数。 |

-两个工具都选择并发调度，因为提供方读取会返回内容，不会修改父 agent（智能体）的状态。
+-----
 
-规范化后的服务结果也是标准工具值：`WebSearchResult` 与 `WebFetchResult`。原生渲染器会保留下文所述的答案、来源和抓取正文文本；提供方对搜索结果数量和正文大小的上限仍属于获取限制，而非仅用于呈现的截断。
+<a id="use-this-package"></a>
+## 使用本包
 
-## 配置
+在已挂载 web 服务与至少一个搜索或抓取后端的组合中加载本包；它把 `web_search` 与 `web_fetch` 加入模型的工具集，并把对应指引加入系统提示词。
 
-| 配置键 | 默认值 | 含义 |
-|---|---|---|
-| `search` | `true` | 注册 `web_search`。 |
-| `fetch` | `true` | 注册 `web_fetch`。 |
-| `searchMaxResults` | `8` | 一次 `web_search` 调用返回的来源数量上限（seam 截断各提供方列表；工具还会限制多查询组合列表）。 |
-| `searchMaxQueries` | `4` | 一次 `web_search` 调用接受的查询数量上限。配置值会出现在提示词指引与 schema 描述中。 |
-| `fetchTimeoutMs` | `30000` | `web_fetch` 的协作式工具调用超时预算（ms）。 |
-| `searchTimeoutMs` | `30000` | `web_search` 的协作式工具调用超时预算（ms）。 |
-| `fetchMaxOutputChars` | `200000` | 同步转换的源字符数与单次完整 `web_fetch` 输出的上限（状态头、渲染后的主体与页脚合并计算）；主体被截断时，在能容纳的情况下附带截断提示。 |
+### 何时选择
 
-`searchMaxQueries` 在完全相同的字符串去重前限制可接受数组、提供方请求扇出与组合后的提供方答案增长；校验会在任何搜索开始前拒绝超限数组，随后分发只保留每个查询第一次出现的位置。该设置与各提供方自己的 `maxUses` 等控制项共同构成产品的搜索预算；通用 seam 不公开提供方内部的原生搜索计数。`fetchTimeoutMs`／`searchTimeoutMs` 声明每个工具的协作式超时预算（附加为 `ToolDefinition.timeoutMs`），由 [`@deepseek-ai/dsh-tool-call-timeout-policy`](../../guard/timeout-policy/README.zh.md) 强制执行；面向模型的 schema 不公开超时参数。`fetchMaxOutputChars` 同时限制同步转换工作量和完整渲染结果：只转换至多该数量的源字符，随后对状态头、转换后的前缀和截断提示合并设限。默认值为本地提供方的 100,000 字符主体上限留出余量，但渲染膨胀仍可能使最终上限截断结果。
+当模型需要发现当前信息或阅读特定页面时选择本包：`web_search` 返回可选的答案与来源 URL，`web_fetch` 以文本形式取回页面内容。只想要其中一个工具的产品通过配置禁用另一个（`{ search: false }` 或 `{ fetch: false }`）；仅当抓取也启用时，搜索指引才会提及 `web_fetch`，仅启用搜索的组合则会要求模型使用返回的 snippet 并引用其 URL。
+
+### 最小配置
+
+加载 web 服务、至少一个后端与本包；两个工具默认都会注册。

+| `fetchMaxOutputChars` | `200000` | 同步转换的源字符数与单次完整 `web_fetch` 输出的上限 |
 
-工具注册遵循产品**启用状态**，而非后端可用性。即使选中的提供方缺失、错误配置、存在歧义或暂时不可用，工具仍保持可见；seam 在执行时解析提供方，执行以结构化 `WebError`（例如 `WEB_PROVIDER_UNAVAILABLE`、`WEB_PROVIDER_AMBIGUOUS`）失败，`ToolRuntime.execute()` 会把它转为模型可读、钩子／UI 可路由的错误工具结果。这样无需把插件加载顺序、凭据状态或 HMR（热模块替换）时机纳入面向模型约定，也能保持模型 schema 稳定。要彻底移除 web 工具，请在此处通过配置将其禁用。
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-tool-web)是每个受支持字段及其 JSDoc 的穷尽式真源。`searchMaxQueries` 在完全相同的字符串去重与提供方请求扇出之前限制可接受的数组；校验会在任何搜索开始前拒绝超限数组。超时预算附加到每个工具定义，由 [`@deepseek-ai/dsh-tool-call-timeout-policy`](../../guard/timeout-policy/README.zh.md) 强制执行；面向模型的 schema 不公开超时参数。
 
-工具绝不会调用提供方的 `available()`，也不会枚举提供方；唯一执行路径是 `ctx.web.search()`／`ctx.web.fetch()`，提供方不可用时，选择机制会在执行阶段抛出结构化 `WebError`，其错误码由工具接收。提供方选择完全留在 seam 内，由单一主体负责。
+### 使用 web_search
 
+用包含 1 至 `searchMaxQueries` 个非空字符串的 `queries` 数组调用 `web_search`。完全相同的查询只执行一次；多个查询并发执行，来源按轮询顺序合并后再应用组合后的 `searchMaxResults` 上限。结果是可选的提供方答案，后接 `Sources:`，每行一个来源——`- [<title-or-url>](<url>)`，可选附 snippet 与日期——以及一句固定的引用 URL 指引。
+
+```text
+web_search({ queries: ['deepseek harness documentation'] })
+```
+
+多查询调用中的任何查询失败时，`web_search` 会中止其余搜索，等待所有已启动搜索结算，丢弃成功结果，并针对首次失败返回 `Error: <message>`。
+
+### 使用 web_fetch
+
+用一个 `url` 调用 `web_fetch`。HTML 主体经过过滤后渲染为 markdown（含 GFM 表格与删除线）；文本主体在不可信内容提示下原样通过。非 2xx 状态会在结果中报告，而不是作为错误抛出。截断内容会追加 `(Content truncated. Fetch a more specific URL or section for the full text.)`。
+
+```text
+web_fetch({ url: 'https://example.com' })
+```
+
+### 稳定注册
+
+工具注册遵循产品启用状态，而非后端可用性：即使选中的提供方缺失、错误配置、存在歧义或暂时不可用，工具仍保持可见。执行随后以结构化 `WebError` 失败——例如 `WEB_PROVIDER_UNAVAILABLE` 或 `WEB_PROVIDER_AMBIGUOUS`——它变成模型可读、钩子或 UI 可路由的错误工具结果。要移除 web 工具，请在此处通过配置将其禁用。
+
+### 失败与恢复
+
+schema 校验会在执行前拒绝缺失或非数组的 `queries` 字段、非字符串数组元素、超限数组或空白 URL，错误消息精确，例如 `Error: queries must contain at least one query` 与 `Error: url must be a non-empty string`。提供方侧失败以结构化错误工具结果呈现；模型可以读取并决定下一步，例如抓取被引用的 URL 或精化查询。

+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释工具背后的设计决策；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+本包建立在一个分离与一条注册规则之上：
+
+- **消费方拥有面向模型的约定。** 工具名称、schema、snake_case 参数名称、提示词区段、结果上限、格式化与呈现都定义在这里；提供方选择完全留在 `ctx.web` 内部。工具绝不会调用提供方的 `available()`，也绝不枚举提供方——唯一执行路径是 `ctx.web.search()`／`ctx.web.fetch()`。
+- **启用状态驱动注册。** 工具在配置启用时注册，与后端可用性无关，因此插件加载顺序、凭据状态与 HMR（热模块替换）时机永远不会进入面向模型的约定。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：配置 schema、启用状态、超时预算、工具注册 |
+| [`src/search.ts`](src/search.ts) | `web_search` 工具：参数校验、查询扇出、合并、格式化、呈现元数据 |
+| [`src/fetch.ts`](src/fetch.ts) | `web_fetch` 工具：HTML→markdown 转换、输出上限、格式化、呈现元数据 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；约定在工具处强制执行） |
+
+### 搜索流程
+
+`web_search` 校验参数（非空数组、数量上限、非空白字符串），把完全相同的重复查询折叠为首现位置，然后通过 `ctx.web` 并发执行 1 至 `searchMaxQueries` 个不同搜索。失败通过融合信号中止批次；调用会等待每个已启动搜索结算后才返回首次失败。成功结果按排名轮询合并、按 URL 去重、在 `searchMaxResults` 处截断，并格式化为面向模型的文本。
+
+### 抓取流程
+
+`web_fetch` 在共享 turndown 转换器渲染 GFM 表格与删除线之前删除活动和隐藏 HTML。词法嵌套守卫与转换失败会产生固定的省略标记，而不是返回不安全的原始 HTML；同步转换上限约束 DOM 工作量。完整输出——状态头、不可信内容提示、渲染正文与截断页脚——随后作为整体设界。转换按结果与上限记忆化，使注册表渲染与呈现共享一次解析。
+
+### 呈现
+
+每个工具都在其结果（`output.presentationMeta`）上附加结构化元数据——保真的搜索来源，或抓取摘要（最终 URL、状态码、有效截断）——使 UI 可以渲染 `web` 结果卡片，回放也能复现它们，而无需重新解析有损的渲染文本。不具备 `web` 能力的 UI 回退到原始工具结果，也就是同一份文本。

 # @deepseek-ai/dsh-web-fetch-http
 
 English | [中文](README.zh.md)
 
-An anonymous public HTTP(S) `WebFetchProvider` for the harness [web capability seam](../web/README.md) (`ctx.web`). It retrieves a concrete URL and returns a status code plus bounded decoded content.
+## Summary
 
-This is an **implementation** package: it registers a provider into `ctx.web`, it does not own the key and it does not register a model-facing tool. It is a function/namespace plugin (`inject: ['web']`).
+With `dsh-web-fetch-http`, the harness can fetch public HTTP(S) pages through the web service (`ctx.web`) and get their status code plus bounded, decoded content without sending credentials. Choose it when a composition needs safe retrieval with URL validation, public-address resolution, connection pinning, same-origin redirects, byte and character caps, and an explicit product `User-Agent`. It returns non-2xx responses as results rather than errors, and rejects non-public destinations, binary data, and unsupported content types. The model-facing `web_fetch` tool lives in `dsh-tool-web`, which renders this provider's bodies.
 
-## Responsibility split
+## Table of Contents
 
-The provider owns **safe resource retrieval**: URL validation, public-address resolution and connection pinning, HTTP transport, redirect policy, a resource-backstop timeout, abort propagation, byte caps, charset decoding, content-type classification, and binary rejection. `@deepseek-ai/dsh-tool-web` owns **presentation** (HTML→markdown, truncation formatting). A non-2xx HTTP response is a *result* (status code + decoded body), not an error; `WebError` is reserved for failures to safely retrieve or represent the resource.

+- [Further Exploration](#further-exploration)
+- [Model Experience](#model-experience)
+- [Known Limitations and Deferred Work](#known-limitations-and-deferred-work)
+- [Dev Note](#dev-note)
 
-The provider's `timeoutMs` is a resource backstop for direct `ctx.web.fetch()` callers and misconfigured deployments, not the model-facing tool-call budget. [`dsh-tool-call-timeout-policy`](../../guard/timeout-policy/README.md) owns the `web_fetch` tool-call budget by arming `exec.signal`.
+-----
 
-A shipping web-tool deployment sets the provider backstop above the tool budget, so model calls normally return `TOOL_TIMEOUT`. If the outer deadline reaches the provider first, the provider reports `WEB_ABORTED` and the outer policy replaces it with `TOOL_TIMEOUT`. `WEB_FETCH_TIMEOUT` therefore identifies a direct service caller whose provider budget elapsed.
+<a id="use-this-package"></a>
+## Use this package
 
-## Transport hygiene
+Mount the provider in a composition that already loads the web service; it registers as the `http` fetch provider, so `ctx.web.fetch()` resolves it automatically when it is the only usable fetch backend — or pin it with `fetchProvider: http`.
 
-- Accepts only `http:` and `https:` URLs; rejects credentials in URLs (`WEB_BLOCKED_URL`) and URLs over the fixed 2,048-character security limit or otherwise malformed (`WEB_INVALID_URL`).
-- Resolves each hostname once, rejects the complete answer set if any IPv4 or IPv6 destination is not public unicast (`WEB_BLOCKED_URL`), and pins the connection to that validated set. For IPv6 answers it discovers the active DNS64 prefix through `ipv4only.arpa` and rejects NAT64 translations to non-public IPv4. This blocks loopback, private, link-local, carrier-grade NAT, multicast, reserved, transition, translation, and private IPv4-mapped IPv6 destinations without resolving the target hostname twice.
-- Enforces the URL limit, response byte cap (`WEB_FETCH_TOO_LARGE`), decoded body character cap, timeout (`WEB_FETCH_TIMEOUT`), and redirect hop cap.
-- Propagates the caller's abort signal (`WEB_ABORTED`) into the network request and the streaming read.
-- Follows only **same-origin** redirects; each followed hop repeats public-address resolution and pinning, while a cross-origin redirect fails with `WEB_REDIRECT_BLOCKED` and requires a fresh tool call (the model of Claude Code's WebFetch).
-- Sends an explicit product `User-Agent`, never a browser disguise.
-- Rejects unsupported (e.g. binary) content types with `WEB_UNSUPPORTED_CONTENT_TYPE`.
+### When to choose it
 
-Direct `HttpFetchProvider` construction may inject an `HttpFetchResolver` for alternate trusted assemblies and deterministic tests. That resolver must reject every non-public destination before returning addresses; the shipped plugin always uses the built-in public-address resolver.
+Choose this backend when a deployment must fetch public pages with bounded output and safe transport: no credentials are sent, every resolved address must be public, each connection is pinned to the validated answer set, redirects cannot escape the origin, and every response is capped.
 
-## Config
+### Minimal configuration
 
-| Key | Default | Meaning |
+Load the web service and the provider; configurable limits have safe defaults and validate at plugin construction, so an invalid value fails loudly instead of building a provider with nonsensical caps. The URL security limit is fixed at 2,048 characters.
+
+```yaml
+- name: '@deepseek-ai/dsh-web'
+- name: '@deepseek-ai/dsh-web-fetch-http'
+```
+
+| Field | Default | Meaning |
 |---|---|---|
-| `maxResponseBytes` | `5_000_000` | Maximum response body size in bytes. |
-| `maxBodyChars` | `100_000` | Maximum decoded body length in characters. |
-| `timeoutMs` | `30_000` | Fetch timeout within Node's timer range — a resource backstop for direct `ctx.web.fetch()` callers, not the model-facing tool-call budget (that is `dsh-tool-call-timeout-policy`). |
-| `maxRedirects` | `5` | Maximum same-origin redirect hops (`0` follows none). |
-| `userAgent` | `deepseek-harness/…` | `User-Agent` header. |
+| `maxResponseBytes` | `5,000,000` | Maximum response body size in bytes |
+| `maxBodyChars` | `100,000` | Maximum decoded body length in characters |
+| `timeoutMs` | `30,000` | Fetch timeout — a resource backstop, not the model-facing tool budget |
+| `maxRedirects` | `5` | Maximum same-origin redirect hops (`0` follows none) |
+| `userAgent` | `deepseek-harness/…` | `User-Agent` header sent on every request |
 
-The configurable numeric limits are validated at plugin construction: every cap except `maxRedirects` must be a positive finite number, and `maxRedirects` must be a non-negative integer. An invalid value throws rather than silently constructing a provider with nonsensical limits.
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-web-fetch-http) is the exhaustive source for every accepted field and its JSDoc.
 
+### What a fetch returns
+
+A successful call yields a `WebFetchResult`: the final URL after allowed redirects, the HTTP status code, a decoded body classified as `html` or `text`, and a `truncated` flag. A non-2xx response is a result, not an error — the status code is part of the fetched resource state; `WebError` is reserved for failures to safely retrieve or represent the resource.
+
+```text
+const page = await ctx.web.fetch({ url: 'https://example.com' })
+// page.body.kind === 'html' | 'text'; page.statusCode === 200 | 404 | ...
+```
+
+### Transport behavior
+
+The provider keeps requests anonymous and bounded: it accepts only `http:` and `https:` URLs without embedded credentials and rejects URLs over 2,048 characters. It resolves each hostname once, rejects the complete result if any IPv4 or IPv6 address is not public unicast, and pins the connection to that validated set. IPv6 checks discover the active DNS64 prefix and reject translations to non-public IPv4. Each same-origin redirect repeats resolution and pinning; cross-origin redirects fail and require a fresh call. The provider also enforces byte, character, hop, and time caps, rejects unsupported content types, and sends an explicit product `User-Agent`.
+
+### Failures and recovery
+
+Failures throw `WebError` with a machine-routable code: `WEB_INVALID_URL`, `WEB_BLOCKED_URL`, `WEB_FETCH_TOO_LARGE`, `WEB_FETCH_TIMEOUT`, `WEB_REDIRECT_BLOCKED`, `WEB_UNSUPPORTED_CONTENT_TYPE`, `WEB_ABORTED`, or `WEB_PROVIDER_ERROR`. Direct callers can route on the code; the model-facing `web_fetch` tool surfaces the failure text to the model under its own error wrapper.

+## Understand the implementation

+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the provider; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The package is built on one separation and one layered timeout:
+
+- **Safe retrieval vs. presentation.** This provider owns URL validation, public-address enforcement, connection pinning, HTTP transport, redirect policy, caps, charset decoding, and binary rejection; `dsh-tool-web` owns HTML→markdown and truncation formatting. A non-2xx response is data, not failure.
+- **Two timeout layers.** The provider's `timeoutMs` is a resource backstop for direct `ctx.web.fetch()` callers; the model-facing tool-call budget belongs to `dsh-tool-call-timeout-policy`, which arms `exec.signal`. When the outer deadline fires first the provider reports `WEB_ABORTED` and the policy replaces it with `TOOL_TIMEOUT`; `WEB_FETCH_TIMEOUT` therefore identifies a direct service caller whose provider budget elapsed.

+
+### Read path
+
+A fetch validates the URL, resolves the hostname once, rejects the complete answer set when any address is not public, and pins the connection to the accepted addresses. It repeats that check for each same-origin redirect; a cross-origin redirect or non-public target fails before response bytes are accepted. The final response is classified by `Content-Type`, decoded from its declared charset, and read under the byte cap; the decoded text is then truncated to the character cap.

 # @deepseek-ai/dsh-web-fetch-http
 
 [English](README.md) | 中文
 
-一个匿名公共 HTTP(S) `WebFetchProvider`，用于 harness [web 能力 seam](../web/README.zh.md)（`ctx.web`）。它获取具体 URL，返回状态码和长度受限的解码内容。
+## 概述
 
-这是一个**实现**包：它向 `ctx.web` 注册提供方，不拥有该键，也不注册面向模型的工具。它是函数／命名空间插件（`inject: ['web']`）。
+有了 `dsh-web-fetch-http`，harness 可以通过 web 服务（`ctx.web`）抓取公共 HTTP(S) 页面，并在不发送凭据的情况下获得状态码与有界、解码后的内容。当组合需要 URL 校验、公开地址解析、连接固定、仅同源重定向、字节和字符上限及显式产品 `User-Agent` 时选择它。它把非 2xx 响应作为结果而非错误返回，并拒绝非公开目标、二进制数据与不受支持的内容类型。面向模型的 `web_fetch` 工具位于 `dsh-tool-web`，由它渲染本提供方的正文。
 
-## 职责拆分
+## 目录
 
-提供方拥有**安全资源获取**：URL 验证、公开地址解析与连接固定、HTTP 传输、重定向策略、资源兜底超时、中止传播、字节上限、charset 解码、内容类型分类与二进制拒绝。`@deepseek-ai/dsh-tool-web` 拥有**呈现**（HTML→markdown、截断格式）。非 2xx HTTP 响应是*结果*（状态码 + 解码主体），不是错误；`WebError` 只用于无法安全获取或表示资源的失败。

-提供方的 `timeoutMs` 是直接 `ctx.web.fetch()` 调用方和配置有误的部署所用的资源兜底，不是面向模型的工具调用预算。[`dsh-tool-call-timeout-policy`](../../guard/timeout-policy/README.zh.md) 拥有 `web_fetch` 工具调用预算，并让 `exec.signal` 在超时时触发，以强制执行该预算。
+-----
 
-已交付的 web 工具部署会把提供方兜底设为高于工具预算，因此模型调用通常返回 `TOOL_TIMEOUT`。如果外层截止期限先于提供方的兜底超时触发，提供方会报告 `WEB_ABORTED`，外层策略再将其替换为 `TOOL_TIMEOUT`。因此，`WEB_FETCH_TIMEOUT` 表明直接服务调用方的提供方预算已经耗尽。
+<a id="use-this-package"></a>
+## 使用本包
 
-## 传输卫生
+在已加载 web 服务的组合中挂载本提供方；它以 `http` 抓取提供方身份注册，因此当它是唯一可用的抓取后端时，`ctx.web.fetch()` 会自动解析到它——也可以用 `fetchProvider: http` 固定。
 
-- 只接受 `http:` 和 `https:` URL；拒绝 URL 中的凭据（`WEB_BLOCKED_URL`），也拒绝超过固定 2,048 字符安全上限或格式错误的 URL（`WEB_INVALID_URL`）。
-- 每个 hostname 只解析一次；如果完整解析结果中任一 IPv4 或 IPv6 目的地址不是公开单播地址，则以 `WEB_BLOCKED_URL` 拒绝；连接只使用这一组已验证地址。对于 IPv6 结果，它通过 `ipv4only.arpa` 发现当前 DNS64 前缀，并拒绝转换到非公开 IPv4 的 NAT64 地址。该策略会阻断 loopback、私有、link-local、运营商级 NAT、多播、保留、过渡、转换和映射到私有 IPv4 的 IPv6 地址，且不会对目标 hostname 进行第二次解析。
-- 强制执行 URL 上限、响应字节上限（`WEB_FETCH_TOO_LARGE`）、解码主体字符上限、超时（`WEB_FETCH_TIMEOUT`）和重定向跳数上限。
-- 把调用方的中止信号（`WEB_ABORTED`）传播到网络请求与流式读取。
-- 只跟随**同源**重定向；每个跟随的跳转都会再次执行公开地址解析与连接固定，跨源重定向则以 `WEB_REDIRECT_BLOCKED` 失败并要求发起新的工具调用（沿用 Claude Code 的 WebFetch 模式）。
-- 发送显式的产品 `User-Agent`，绝不伪装成浏览器。
-- 不受支持的内容类型（例如二进制）以 `WEB_UNSUPPORTED_CONTENT_TYPE` 拒绝。
+### 何时选择
 
-直接构造 `HttpFetchProvider` 时，可以为受信任的替代装配和确定性测试注入 `HttpFetchResolver`。该 resolver 必须先拒绝所有非公开目的地址，再返回地址；随产品交付的插件始终使用内置的公开地址 resolver。
+当部署必须以有界输出和安全传输抓取公共页面时选择此后端：不发送凭据，每个已解析地址必须是公共地址，每次连接都固定到已校验的地址集合，重定向无法逃出源站，每个响应都有上限。
 
-## 配置
+### 最小配置
 
-| 配置键 | 默认值 | 含义 |
+加载 web 服务与本提供方；可配置上限都有安全默认值，并在插件构造时验证，因此无效值会响亮地失败，而不是构造出上限荒谬的提供方。URL 安全上限固定为 2,048 个字符。
+
+```yaml
+- name: '@deepseek-ai/dsh-web'
+- name: '@deepseek-ai/dsh-web-fetch-http'
+```
+
+| 字段 | 默认值 | 含义 |
 |---|---|---|
-| `maxResponseBytes` | `5_000_000` | 响应主体最大字节数。 |
-| `maxBodyChars` | `100_000` | 解码主体最大字符数。 |
-| `timeoutMs` | `30_000` | Node 定时器范围内的抓取超时：直接 `ctx.web.fetch()` 调用方的资源兜底，而非面向模型的工具调用预算（后者属于 `dsh-tool-call-timeout-policy`）。 |
-| `maxRedirects` | `5` | 同源重定向最大跳数（`0` 表示完全不跟随）。 |
-| `userAgent` | `deepseek-harness/…` | `User-Agent` 标头。 |
+| `maxResponseBytes` | `5,000,000` | 响应主体最大字节数 |
+| `maxBodyChars` | `100,000` | 解码主体最大字符数 |
+| `timeoutMs` | `30,000` | 抓取超时——资源兜底，不是面向模型的工具预算 |
+| `maxRedirects` | `5` | 同源重定向最大跳数（`0` 表示不跟随） |
+| `userAgent` | `deepseek-harness/…` | 每次请求发送的 `User-Agent` 标头 |
 
-可配置的数值限制会在插件构造时验证：除 `maxRedirects` 外，每个上限都必须是正的有限数；`maxRedirects` 必须是非负整数。无效值会抛出异常，不会静默构造限制荒谬的提供方。
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-web-fetch-http)是每个受支持字段及其 JSDoc 的穷尽式真源。
 
+### 抓取返回什么
+
+成功调用产生 `WebFetchResult`：允许的重定向之后的最终 URL、HTTP 状态码、分类为 `html` 或 `text` 的解码正文，以及 `truncated` 标志。非 2xx 响应是结果而非错误——状态码是被抓取资源状态的一部分；`WebError` 只用于无法安全获取或表示资源的失败。
+
+```text
+const page = await ctx.web.fetch({ url: 'https://example.com' })
+// page.body.kind === 'html' | 'text'; page.statusCode === 200 | 404 | ...
+```
+
+### 传输行为
+
+提供方保持请求匿名且有界：只接受不含内嵌凭据且不超过 2,048 个字符的 `http:` 与 `https:` URL。它只解析一次主机名；只要结果中有任何 IPv4 或 IPv6 地址不是公共单播地址，就拒绝整个结果，并把连接固定到已校验的地址集合。IPv6 检查会发现活动 DNS64 前缀，并拒绝指向非公开 IPv4 的转换地址。每次同源重定向都会重复解析与固定；跨源重定向会失败并要求重新调用。提供方还强制执行字节、字符、跳数和时间上限，拒绝不支持的内容类型，并发送显式产品 `User-Agent`。
+
+### 失败与恢复
+
+失败抛出携带可按机器路由 code 的 `WebError`：`WEB_INVALID_URL`、`WEB_BLOCKED_URL`、`WEB_FETCH_TOO_LARGE`、`WEB_FETCH_TIMEOUT`、`WEB_REDIRECT_BLOCKED`、`WEB_UNSUPPORTED_CONTENT_TYPE`、`WEB_ABORTED` 或 `WEB_PROVIDER_ERROR`。直接调用方可以按 code 路由；面向模型的 `web_fetch` 工具会在自己的错误包装层内把失败文本呈现给模型。

+
+本节解释提供方背后的设计决策；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+本包建立在一个分离与一个分层超时之上：
+
+- **安全获取与呈现分离。** 本提供方拥有 URL 校验、公开地址强制规则、连接固定、HTTP 传输、重定向策略、上限、charset 解码与二进制拒绝；`dsh-tool-web` 拥有 HTML→markdown 与截断格式化。非 2xx 响应是数据，不是失败。
+- **两层超时。** 提供方的 `timeoutMs` 是直接 `ctx.web.fetch()` 调用方的资源兜底；面向模型的工具调用预算属于 `dsh-tool-call-timeout-policy`，由它触发 `exec.signal`。外层截止期限先到时，提供方报告 `WEB_ABORTED`，策略再以 `TOOL_TIMEOUT` 替换；因此 `WEB_FETCH_TIMEOUT` 标识的是提供方预算耗尽的直接服务调用方。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：配置 schema、上限验证、提供方注册 |
+| [`src/provider.ts`](src/provider.ts) | `HttpFetchProvider`：固定连接、重定向跟随、有界读取、charset 解码 |
+| [`src/network.ts`](src/network.ts) | 公开地址解析、DNS64 发现与连接固定 |
+| [`src/policy.ts`](src/policy.ts) | URL 校验、同源检查、内容类型分类、charset 解析 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；上限在提供方处强制执行） |
+
+### 读取路径
+
+抓取先校验 URL，只解析一次主机名，结果中只要有非公开地址就拒绝，并把连接固定到已接受地址。每次同源重定向都重复该检查；跨源重定向或非公开目标在接收响应字节前失败。最终响应按 `Content-Type` 分类、依声明的 charset 解码，并在字节上限内读取；解码后的文本再截断到字符上限。

 # @deepseek-ai/dsh-web-search-deepseek
 
 English | [中文](README.zh.md)
 
-A [DeepSeek](https://deepseek.com)-backed `WebSearchProvider` for the harness [web capability seam](../web/README.md) (`ctx.web`). It calls DeepSeek's **Anthropic-compatible Messages API** (`POST {baseURL}/messages`) with the native `web_search_20250305` server tool enabled, and maps the structured `web_search_tool_result` blocks DeepSeek returns into the seam's normalized `WebSearchResult`.
+## Summary
 
-This is an **implementation** package: it registers a provider into `ctx.web`, resolves its credential for each search through the optional `ctx.credentials` seam, records the auxiliary request in the initiating Agent session when one exists, and does not register a model-facing tool. Like `@deepseek-ai/dsh-llm-deepseek`, it is a function/namespace plugin (`inject: ['web']`). The Anthropic wire shape is a provider-private detail — it does **not** make this provider depend on `ctx.llm`.
+With `dsh-web-search-deepseek`, the harness searches the web through DeepSeek's native search using an existing `DEEPSEEK_API_KEY`. Choose it when a deployment wants DeepSeek native search and accepts that one search costs a full model turn in latency and tokens, because DeepSeek exposes no dedicated search endpoint. Results come from the structured search blocks DeepSeek returns, never from scraping text out of a reply. A missing credential fails the call with a structured error; a response without a search-result block fails loudly rather than degrading. The model-facing `web_search` tool lives in `dsh-tool-web`.
 
-## How it differs from a dedicated search endpoint
+## Table of Contents
 
-Exa and Perplexity expose dedicated search endpoints; DeepSeek does not. Instead this provider issues a **full Messages model call** carrying the `web_search` server tool, so one search costs a complete model turn in latency and tokens — heavier than a pure retrieval endpoint. DeepSeek runs the search server-side and returns **structured** `web_search_tool_result` blocks; the provider parses those blocks and **never scrapes URLs out of model prose**.

+- [Further Exploration](#further-exploration)
+- [Model Experience](#model-experience)
+- [Known Limitations and Deferred Work](#known-limitations-and-deferred-work)
+- [Dev Note](#dev-note)
 
-**Strict mode**: if the response carries no `web_search_tool_result` block (native search did not trigger), the provider throws `WebError` `WEB_PROVIDER_ERROR` rather than degrading to prose-scraping.
+-----
 
-It reuses the `DEEPSEEK_API_KEY` credential reference (no new secret) but **not** `$DEEPSEEK_BASE_URL`: the search endpoint is the Anthropic-compatible base (`https://api.deepseek.com/anthropic/v1`), distinct from the chat-completions base (`https://api.deepseek.com`) the LLM adapter uses. A mounted credentials service is authoritative; without one, the provider falls back to the launching process environment. The reference is resolved for each search, so a key stored or rotated by the Web Models page reaches the next call without a restart.
+<a id="use-this-package"></a>
+## Use this package
 
-## Config
+Mount the provider in a composition that already loads the web service; it registers as the `deepseek-official` search provider, so `ctx.web.search()` resolves it automatically when it is the only usable search backend — or pin it with `searchProvider: deepseek-official`.
 
-| Key | Default | Meaning |
-|---|---|---|
-| `apiKey` | omitted | Literal DeepSeek API key. Prefer `apiKeyEnv` so no secret enters configuration; a non-empty literal wins. |
-| `apiKeyEnv` | `DEEPSEEK_API_KEY` | Credential reference resolved for each search through `ctx.credentials`, or from the process environment when that seam is absent. A missing value fails the call as `WEB_PROVIDER_CREDENTIAL_MISSING`. |
-| `baseURL` | `https://api.deepseek.com/anthropic/v1` | Anthropic-compatible endpoint base; `/messages` is appended. Falls back to `$DEEPSEEK_SEARCH_BASE_URL` from any environment layer; do not reuse `$DEEPSEEK_BASE_URL`, which belongs to the chat-completions LLM adapter. An unparseable value makes the provider unavailable. |
-| `model` | `deepseek-v4-flash` | Anthropic-format model name. |
-| `apiVersion` | `2023-06-01` | `anthropic-version` header value. |
-| `maxTokens` | `4096` | Positive-integer upper bound on generated tokens for the Messages request. |
-| `maxUses` | `5` | Positive-integer maximum `web_search` server-tool uses per request. |
+### When to choose it
+
+Choose this backend when a deployment wants DeepSeek's native server-side web search and already holds a `DEEPSEEK_API_KEY` — the provider reuses that credential reference. One search is heavier than a dedicated retrieval endpoint: DeepSeek runs the search inside a full model turn, so expect one Messages call's latency and generated tokens per search, with up to `maxUses` server-side searches per request. Avoid it when per-search cost or latency dominates.
+
+### Minimal configuration
+
+Load the web service and the provider; the key resolves from `ctx.credentials` when that service is mounted, otherwise from the process environment. The search endpoint uses the Anthropic-compatible base (`https://api.deepseek.com/anthropic/v1`), distinct from the chat-completions base the LLM adapter uses — never reuse `$DEEPSEEK_BASE_URL`.
 
 ```yaml
-- id: web-search-deepseek
-  name: '@deepseek-ai/dsh-web-search-deepseek'
+- name: '@deepseek-ai/dsh-web'
+- name: '@deepseek-ai/dsh-web-search-deepseek'
   config:
     apiKeyEnv: DEEPSEEK_API_KEY
     baseURL: https://gateway.internal/anthropic/v1
 ```
 
-The entry above is the base layer of the `web-search-deepseek` Settings section: a user layer over it reaches the NEXT search, because the provider projects the section per call rather than capturing it at registration. The seam's provider selection therefore never flickers when an endpoint or model changes. `apiKey` carries `role('secret')`, so it never rides a `describe()` response in any layer — a configuration surface learns only whether the credentials domain holds a value for the reference `apiKeyEnv` names, never whether a layer carries a literal key.
+| Field | Default | Meaning |
+|---|---|---|
+| `apiKey` | omitted | Literal DeepSeek API key; prefer `apiKeyEnv` so no secret enters configuration. A non-empty literal wins |
+| `apiKeyEnv` | `DEEPSEEK_API_KEY` | Credential reference resolved for each search through `ctx.credentials`, or from the process environment when that service is absent. A missing value fails the call as `WEB_PROVIDER_CREDENTIAL_MISSING` |
+| `baseURL` | `https://api.deepseek.com/anthropic/v1` | Anthropic-compatible endpoint base; `/messages` is appended. Falls back to `$DEEPSEEK_SEARCH_BASE_URL`; an unparseable value makes the provider unavailable |
+| `model` | `deepseek-v4-flash` | Anthropic-format model name |
+| `apiVersion` | `2023-06-01` | `anthropic-version` header value |
+| `maxTokens` | `4096` | Positive-integer upper bound on generated tokens for the Messages request |
+| `maxUses` | `5` | Positive-integer maximum `web_search` server-tool uses per request |
 
-## Mapping
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-web-search-deepseek) is the exhaustive source for every accepted field and its JSDoc. The entry above is the base layer of the provider's Settings section; a user layer over it reaches the next search, because the provider projects the section per call rather than capturing it at registration.
 
-DeepSeek returns no provider-generated answer content this provider trusts as `content`, so `content` is omitted. `sources[]` comes from `web_search_result` items inside `web_search_tool_result` blocks: `url` ← `url`, `title` ← `title`, and `publishedAt` ← `page_age`. Snippets live separately as URL-keyed `cited_text` entries in a text block's `citations[]`; the provider joins them, leaving `snippet` absent when no excerpt exists.
+### What a search returns

It carries the resolved endpoint, API version, and the exact secret-free JSON body sent to DeepSeek; headers and credentials are excluded. Credential failures and cancellations before dispatch create no event, while later HTTP or response failures leave the attempted request durable.

+### Failures and recovery
 
+Failures throw `WebError` with a machine-routable code: a missing credential is `WEB_PROVIDER_CREDENTIAL_MISSING`, caller cancellation is `WEB_ABORTED`, and provider or transport failures — including a response with no `web_search_tool_result` block — are `WEB_PROVIDER_ERROR`. HTTP redirects are rejected before the `Location` target is contacted. The model-facing `web_search` tool surfaces failure text to the model under its own error wrapper.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the provider; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The provider is built on two commitments:
+
+- **Structured blocks only.** DeepSeek runs the search server-side and returns structured `web_search_tool_result` blocks; the provider parses those blocks and never scrapes URLs out of model prose. In strict mode, a response with no such block throws `WEB_PROVIDER_ERROR` instead of degrading.
+- **One credential, resolved per search.** The provider reuses the `DEEPSEEK_API_KEY` reference (no new secret) but not `$DEEPSEEK_BASE_URL`, because search speaks the Anthropic-compatible Messages API. A mounted credentials service is authoritative; without one the provider falls back to the launching process environment. Resolving per call means a key stored or rotated in the Web Models page reaches the next search without a restart.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: config schema, Settings section installation, per-search option projection |
+| [`src/provider.ts`](src/provider.ts) | The `DeepSeekSearchProvider`: Messages request dispatch, block parsing, citation joining, credential resolution |
+| [`src/types.ts`](src/types.ts) | Anthropic wire types for the search response |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; contracts are enforced at the service) |
+
+### Request flow
+
+Each search projects the current Settings section into provider options — endpoint, model, key reference, limits — then resolves the credential reference through `ctx.credentials` (or the environment), appends the log-only session event, and dispatches the Messages request with the native `web_search` server tool. The response's `web_search_tool_result` blocks become `sources[]`; `cited_text` entries from text blocks are joined to their URLs as snippets; results are deduplicated by URL; and the service enforces the requested source bound on the way back.

 - **One search costs a full Messages model turn** — latency plus generated tokens, with up to `maxUses` server-side searches; DeepSeek exposes no dedicated retrieval endpoint.
-- **Dynamic credential availability resolves inside the operation** — the synchronous `available()` contract can establish that a resolver exists but cannot query an asynchronous credential store. A selected keyless provider therefore fails the search with `WEB_PROVIDER_CREDENTIAL_MISSING`; the stable `web_search` schema remains registered. Caller cancellation races this preflight locally, but cannot force an arbitrary credential backend itself to stop work.
-- **Over-returned sources still cost tokens** — with no result-count knob on the wire, `maxResults` is enforced only post-hoc by seam truncation.
-- **Uncited results carry no `snippet`** — a source gains one only when a `text` block citation (`cited_text`) matches its URL.

 # @deepseek-ai/dsh-web-search-deepseek
 
 [English](README.md) | 中文
 
-由 [DeepSeek](https://deepseek.com) 支持的 `WebSearchProvider`，用于 harness [web 能力 seam](../web/README.zh.md)（`ctx.web`）。它调用 DeepSeek 的 **Anthropic 兼容 Messages API**（`POST {baseURL}/messages`），启用原生 `web_search_20250305` 服务器工具，并把 DeepSeek 返回的结构化 `web_search_tool_result` 块映射为 seam 规范化的 `WebSearchResult`。
+## 概述
 
-这是一个**实现**包：它向 `ctx.web` 注册提供方，通过可选的 `ctx.credentials` seam 为每次搜索解析凭据，若存在发起请求的 agent（智能体）会话，还会在其中记录该辅助请求，且不注册面向模型的工具。与 `@deepseek-ai/dsh-llm-deepseek` 一样，它是函数／命名空间插件（`inject: ['web']`）。Anthropic 协议格式（wire format）是提供方私有细节，并**不**使该提供方依赖 `ctx.llm`。
+有了 `dsh-web-search-deepseek`，harness 可以通过 DeepSeek 原生搜索检索 web，使用部署已有的 `DEEPSEEK_API_KEY`。当部署希望使用 DeepSeek 原生搜索、并接受一次搜索在延迟与 token 上消耗一个完整模型轮次时选择它，因为 DeepSeek 不提供专用搜索端点。结果来自 DeepSeek 返回的结构化搜索块，绝不会从回复文本中抓取。凭据缺失时调用以结构化错误失败；响应缺少搜索结果块时会响亮地失败，而非降级。面向模型的 `web_search` 工具位于 `dsh-tool-web`。
 
-## 与专用搜索端点的区别
+## 目录
 
-Exa 和 Perplexity 提供专用搜索端点，DeepSeek 则没有。该提供方改为发起一次携带 `web_search` 服务器工具的**完整 Messages 模型调用**，因此一次搜索会产生完整模型轮次的延迟与 token 开销，比纯检索端点更重。DeepSeek 在服务器侧执行搜索，返回**结构化** `web_search_tool_result` 块；提供方解析这些块，**绝不会从模型文本中抓取 URL**。

-**严格模式**：如果响应不含 `web_search_tool_result` 块（未触发原生搜索），提供方会抛出 `WebError` `WEB_PROVIDER_ERROR`，而非降级为文本抓取。
+-----
 
-它复用 `DEEPSEEK_API_KEY` 凭据引用（不增加密钥），但**不会**复用 `$DEEPSEEK_BASE_URL`：搜索端点使用 Anthropic 兼容基址（`https://api.deepseek.com/anthropic/v1`），不同于 LLM（大语言模型）适配器使用的 chat-completions 基址（`https://api.deepseek.com`）。已挂载的凭据服务具有权威性；没有该服务时，提供方会回退到启动进程的环境变量。每次搜索都会解析该引用，因此在 Web 的 Models 页中存储或轮换的密钥无需重启，即可用于下一次调用。

-| `baseURL` | `https://api.deepseek.com/anthropic/v1` | Anthropic 兼容端点基址；追加 `/messages`。缺省时回退到任一环境层中的 `$DEEPSEEK_SEARCH_BASE_URL`；禁止复用属于 chat-completions LLM 适配器的 `$DEEPSEEK_BASE_URL`。无法解析时提供方不可用。 |

+### 何时选择
+
+当部署希望使用 DeepSeek 原生服务端 web 搜索、且已持有 `DEEPSEEK_API_KEY` 时选择此后端——提供方复用该凭据引用。一次搜索比专用检索端点更重：DeepSeek 在完整模型轮次内执行搜索，因此每次搜索都要预期一次 Messages 调用的延迟与生成 token，每次请求最多 `maxUses` 次服务端搜索。当单次搜索的成本或延迟占主导时避免使用它。
+
+### 最小配置
+
+加载 web 服务与本提供方；密钥在已挂载 `ctx.credentials` 服务时从其解析，否则从进程环境解析。搜索端点使用 Anthropic 兼容基址（`https://api.deepseek.com/anthropic/v1`），不同于 LLM（大语言模型）适配器使用的 chat-completions 基址——绝不复用 `$DEEPSEEK_BASE_URL`。

     baseURL: https://gateway.internal/anthropic/v1
 ```
 
-上面的条目是 `web-search-deepseek` Settings 段的 base 层：叠加其上的用户层会作用于**下一次**搜索，因为提供方是按次投影该段，而不是在注册时固化它。因此端点或模型变化时，seam 的提供方选择不会闪断。`apiKey` 带有 `role('secret')`，所以它在任何一层都不会出现在 `describe()` 响应中——配置表层只能知道 credentials 领域是否为 `apiKeyEnv` 所命名的引用持有值，而无从知道某一层是否带着字面密钥。

+### 设计理念
+
+本提供方建立在两项承诺之上：
+
+- **只取结构化块。** DeepSeek 在服务端执行搜索并返回结构化的 `web_search_tool_result` 块；提供方解析这些块，绝不从模型文本中抓取 URL。严格模式下，没有此类块的响应会抛出 `WEB_PROVIDER_ERROR`，而非降级。
+- **一个凭据，逐次解析。** 提供方复用 `DEEPSEEK_API_KEY` 引用（不新增密钥），但不复用 `$DEEPSEEK_BASE_URL`，因为搜索使用 Anthropic 兼容 Messages API。已挂载的凭据服务具有权威性；没有该服务时回退到启动进程的环境。按次解析意味着在 Web 的 Models 页中存储或轮换的密钥无需重启，即可用于下一次搜索。

-An [Exa](https://exa.ai)-backed `WebSearchProvider` for the harness [web capability seam](../web/README.md) (`ctx.web`). It calls Exa's `POST /search` endpoint with highlight contents and maps the flat `results[]` into the seam's normalized `WebSearchResult`.
+## Summary
 
-This is an **implementation** package: it registers a provider into `ctx.web`, it does not own the `ctx.web` key and it does not register a model-facing tool (that is `@deepseek-ai/dsh-tool-web`). Like `@deepseek-ai/dsh-llm-deepseek`, it is a function/namespace plugin (`inject: ['web']`) that registers its backend, not a default-export service.
+With `dsh-web-search-exa`, the harness searches the web through Exa and gets vendor-native results with portable snippets and publication dates. Choose it when a deployment has an Exa API key and wants Exa's keyword or neural search. Exa returns no generated answer, so results carry no `content` — only citeable sources. A result with no non-blank highlight is dropped, so a call can return fewer sources than requested. The model-facing `web_search` tool lives in `dsh-tool-web`.

-| `baseURL` | `https://api.exa.ai` | Endpoint base; `/search` is appended. An unparseable value makes the provider unavailable. |
-| `searchType` | `auto` | Retrieval mode sent as Exa's `type`: `auto` (Exa decides), `keyword`, or `neural`. |
-| `numResults` | (unset) | Default result count when a request carries no `maxResults`. Unset sends no default. Must be a positive integer. |
-| `highlightsPerResult` | `1` | Highlight sentences requested per result (Exa's `highlightsPerUrl`). Must be a positive integer. |

+## Use this package
+
+Mount the provider in a composition that already loads the web service; it registers as the `exa` search provider, so `ctx.web.search()` resolves it automatically when it is the only usable search backend — or pin it with `searchProvider: exa`.
+
+### When to choose it
+
+Choose this backend when a deployment holds an Exa API key and wants Exa's keyword or neural search with per-result highlight snippets and publication dates. The provider is unavailable — and every search call fails with a structured error — when the key is empty or the endpoint base does not parse.
+
+### Minimal configuration
+
+Load the web service and the provider; the API key falls back to `$EXA_API_KEY` from the launch environment, and all other settings have safe defaults.
 
 ```yaml
-- id: web-search-exa
-  name: '@deepseek-ai/dsh-web-search-exa'
+- name: '@deepseek-ai/dsh-web'
+- name: '@deepseek-ai/dsh-web-search-exa'
   config:
     apiKey: !!js process.env.EXA_API_KEY
 ```
 
-## Mapping
+| Field | Default | Meaning |
+|---|---|---|
+| `apiKey` | `$EXA_API_KEY` | Exa API key; empty or absent makes the provider unavailable |
+| `baseURL` | `https://api.exa.ai` | Endpoint base; `/search` is appended. An unparseable value makes the provider unavailable |
+| `searchType` | `auto` | Retrieval mode sent as Exa's `type`: `auto`, `keyword`, or `neural` |
+| `numResults` | (unset) | Default result count when a request carries no `maxResults`; must be a positive integer |
+| `highlightsPerResult` | `1` | Highlight sentences requested per result (Exa's `highlightsPerUrl`); must be a positive integer |
 
-Exa returns a flat `results[]` and no generated answer, so `content` is omitted. Each result maps to a `WebSearchSource`: `url` ← `url`, `title` ← `title`, `snippet` ← the first non-empty `highlights[]` entry (a result with no highlight has no portable snippet and is dropped), `publishedAt` ← `publishedDate`. A request's `maxResults` wins over the configured `numResults` default and is sent as Exa's `numResults` for a cost/latency optimization; the final bound is enforced by the seam. Provider failures (HTTP errors, network failure, unparseable or wrong-shape bodies) surface as `WebError` `WEB_PROVIDER_ERROR`; an aborted request surfaces as `WEB_ABORTED`. HTTP redirects are rejected before the `Location` target is contacted and surface as `WEB_PROVIDER_ERROR`.
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-web-search-exa) is the exhaustive source for every accepted field and its JSDoc.
 
+### What a search returns
+
+Each Exa result maps to a `WebSearchSource`: `url`, `title`, the first non-blank highlight as `snippet`, and `publishedDate` as `publishedAt`; a result with no highlight has no portable snippet and is dropped. A request's `maxResults` wins over the configured `numResults` default and is sent to Exa as a cost and latency optimization — the final bound is enforced by the service, which truncates and flags. Exa returns no generated answer, so the result carries no `content`.
+
+### Failures and recovery
+
+Provider failures — HTTP errors, network failures, unparseable or wrong-shape bodies — surface as `WebError` `WEB_PROVIDER_ERROR`; an aborted request surfaces as `WEB_ABORTED`. HTTP redirects are rejected before the `Location` target is contacted and surface as `WEB_PROVIDER_ERROR`. Callers route on the code; the model-facing `web_search` tool surfaces failures to the model under its own error wrapper.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the provider; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The provider is a thin adapter over Exa's API with two deliberate rules:
+
+- **Portable snippets only.** A source gains a `snippet` only from a real highlight; inventing one from other fields would make the seam lie, so snippet-less results are dropped entirely.
+- **No invented answers.** Exa returns no generated answer, so `content` is omitted rather than fabricating provider prose the model might trust.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: config schema, environment fallback, provider registration |
+| [`src/provider.ts`](src/provider.ts) | The `ExaSearchProvider`: request dispatch, abort classification, result mapping |
+| [`src/types.ts`](src/types.ts) | Exa wire types: `ExaSearchResponse`, `ExaResult`, `ExaError` |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; contracts are enforced at the service) |
+
+### Request and mapping flow
+
+`search()` posts the query, retrieval mode, highlight request, and optional result count to `{baseURL}/search` with `redirect: 'error'`, so a redirect fails the request without contacting the target. The parsed `results[]` are mapped one by one, snippet-less entries dropped, and the service applies the final `maxResults` bound on the way back. An abort — a `DOMException` named `AbortError` — becomes `WEB_ABORTED`; anything else becomes `WEB_PROVIDER_ERROR`.

-- **A result with no non-blank highlight is dropped entirely** — no portable snippet to map, so fewer sources than the requested count can return.
-- **Only `searchType`/`numResults`/`highlightsPerResult` are exposed** — Exa's other controls (livecrawl, category, domain/date filters, full-text contents) wait on provider-neutral Service Definition fields ([seam Agent Note](../../../.agents/notes/implemented/architecture/2026-06-24-web-capability-seam.md)).

 # @deepseek-ai/dsh-web-search-exa
 
 [English](README.md) | 中文
 
-由 [Exa](https://exa.ai) 支持的 `WebSearchProvider`，用于 harness [web 能力 seam](../web/README.zh.md)（`ctx.web`）。它调用 Exa 的 `POST /search` 端点并请求高亮摘要内容，把扁平 `results[]` 映射为 seam 规范化的 `WebSearchResult`。
+## 概述
 
-这是一个**实现**包：它向 `ctx.web` 注册提供方，不拥有 `ctx.web` 键，也不注册面向模型的工具（后者属于 `@deepseek-ai/dsh-tool-web`）。与 `@deepseek-ai/dsh-llm-deepseek` 一样，它是函数／命名空间插件（`inject: ['web']`），负责注册后端，而非默认导出服务。
+有了 `dsh-web-search-exa`，harness 可以通过 Exa 搜索 web，获得带可移植 snippet 与发布日期的厂商原生结果。当部署持有 Exa API 密钥、并希望使用 Exa 的关键词或神经搜索时选择它。Exa 不返回生成答案，因此结果不携带 `content`——只产出可引用的来源。没有非空白高亮的来源会被丢弃，因此一次调用返回的来源可能少于请求数量。面向模型的 `web_search` 工具位于 `dsh-tool-web`。

+
+本节解释提供方背后的设计决策；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+该提供方是 Exa API 之上的薄适配器，遵循两条刻意的规则：
+
+- **只取可移植的 snippet。** 来源只有在真实高亮存在时才获得 `snippet`；用其他字段捏造会让 seam 说谎，因此没有 snippet 的结果被整个丢弃。
+- **不虚构答案。** Exa 不返回生成答案，因此省略 `content`，而不是编造模型可能信任的提供方文本。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：配置 schema、环境变量回退、提供方注册 |
+| [`src/provider.ts`](src/provider.ts) | `ExaSearchProvider`：请求分发、中止分类、结果映射 |
+| [`src/types.ts`](src/types.ts) | Exa 协议类型：`ExaSearchResponse`、`ExaResult`、`ExaError` |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；约定在服务处强制执行） |
+
+### 请求与映射流程
+
+`search()` 以 `redirect: 'error'` 把查询、检索模式、高亮请求与可选结果数 POST 到 `{baseURL}/search`，因此重定向会在不接触目标的情况下使请求失败。解析后的 `results[]` 逐项映射，没有 snippet 的条目被丢弃，服务在返回路径上应用最终的 `maxResults` 上限。中止——名为 `AbortError` 的 `DOMException`——变为 `WEB_ABORTED`；其余情况变为 `WEB_PROVIDER_ERROR`。

 # @deepseek-ai/dsh-web-search-perplexity
 
 English | [中文](README.zh.md)
 
-A [Perplexity](https://perplexity.ai)-backed `WebSearchProvider` for the harness [web capability seam](../web/README.md) (`ctx.web`). It calls Perplexity's OpenAI-compatible `POST /chat/completions` endpoint and maps the generated answer plus citations into the seam's normalized `WebSearchResult`.
+## Summary
 
-This is an **implementation** package: it registers a provider into `ctx.web`, it does not own the key and it does not register a model-facing tool. Like `@deepseek-ai/dsh-llm-deepseek`, it is a function/namespace plugin (`inject: ['web']`). The OpenAI-compatible wire shape is a provider-private detail — it does **not** make this provider depend on `ctx.llm`.
+With `dsh-web-search-perplexity`, the harness searches the web through Perplexity and gets a model-generated answer plus citeable sources in one call. Choose it when a deployment has a Perplexity API key and wants a generated answer. Perplexity has no result-count control, so the returned sources are truncated to the requested bound after the fact. When Perplexity omits structured result metadata, sources fall back to URL-only citations. The model-facing `web_search` tool lives in `dsh-tool-web`.
 
-## Config
+## Table of Contents
 
-| Key | Default | Meaning |
-|---|---|---|
-| `apiKey` | `$PERPLEXITY_API_KEY` | Perplexity API key. Empty/absent makes the provider unavailable. |

-| `model` | `sonar` | Search model name. |
-| `maxTokens` | `1024` | Upper bound on generated answer tokens (`max_tokens`). Must be a positive integer. |
-| `searchRecency` | (unset) | Recency window sent as `search_recency_filter`: `day`, `week`, `month`, or `year`. Unset sends no filter. |

+Choose this backend when a deployment holds a Perplexity API key and wants a model-generated answer plus citeable sources in one search. The provider is unavailable — and every search call fails with a structured error — when the key is empty or the endpoint base does not parse.
+
+### Minimal configuration
+
+Load the web service and the provider; the API key falls back to `$PERPLEXITY_API_KEY` from the launch environment, and all other settings have safe defaults.
 
 ```yaml
-- id: web-search-perplexity
-  name: '@deepseek-ai/dsh-web-search-perplexity'
+- name: '@deepseek-ai/dsh-web'
+- name: '@deepseek-ai/dsh-web-search-perplexity'
   config:
     apiKey: !!js process.env.PERPLEXITY_API_KEY
 ```
 
-## Mapping
+| Field | Default | Meaning |
+|---|---|---|
+| `apiKey` | `$PERPLEXITY_API_KEY` | Perplexity API key; empty or absent makes the provider unavailable |
+| `baseURL` | `https://api.perplexity.ai` | Endpoint base; `/chat/completions` is appended. An unparseable value makes the provider unavailable |
+| `model` | `sonar` | Search model name |
+| `maxTokens` | `1024` | Upper bound on generated answer tokens (`max_tokens`); must be a positive integer |
+| `searchRecency` | (unset) | Recency window sent as `search_recency_filter`: `day`, `week`, `month`, or `year`. Unset sends no filter |
 
-`content` ← `choices[0].message.content` (the generated answer). `sources[]` prefers the structured `search_results[]` (`url`, `title`, `snippet`, `publishedAt` ← `date`), falling back to the URL-only `citations[]` array only when `search_results` is absent — those sources carry just a `url`, which is why `title`/`snippet`/`publishedAt` are optional on the seam. Provider failures surface as `WebError` `WEB_PROVIDER_ERROR`; an aborted request surfaces as `WEB_ABORTED`. HTTP redirects are rejected before the `Location` target is contacted and surface as `WEB_PROVIDER_ERROR`. Perplexity has no result-count control, so `maxResults` is enforced by the seam (truncating `sources[]` and setting `truncated`).
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-web-search-perplexity) is the exhaustive source for every accepted field and its JSDoc.
 
+### What a search returns
+
+`content` carries Perplexity's generated answer. `sources[]` prefers the structured `search_results[]` (`url`, `title`, `snippet`, `publishedAt` from `date`) and falls back to the URL-only `citations[]` array only when `search_results` is absent — which is why `title`/`snippet`/`publishedAt` are optional on the service. Perplexity exposes no result-count control, so the service enforces `maxResults` by truncating and flagging.
+
+### Failures and recovery
+
+Provider failures — HTTP errors, network failures, unparseable or wrong-shape bodies — surface as `WebError` `WEB_PROVIDER_ERROR`; an aborted request surfaces as `WEB_ABORTED`. HTTP redirects are rejected before the `Location` target is contacted and surface as `WEB_PROVIDER_ERROR`. Callers route on the code; the model-facing `web_search` tool surfaces failures to the model under its own error wrapper.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the provider; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The provider is a thin adapter over Perplexity's chat-completions endpoint with two deliberate rules:
+
+- **The generated answer is trusted as `content`.** Unlike the other search backends, Perplexity returns a model-generated answer, and this provider passes it through as the normalized `content` field.
+- **Structured sources win; URL-only citations are the fallback.** `search_results[]` carries the portable fields; `citations[]` carries only URLs, and the service vocabulary makes those fields optional precisely for this case.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: config schema, environment fallback, provider registration |
+| [`src/provider.ts`](src/provider.ts) | The `PerplexitySearchProvider`: request dispatch, abort classification, answer and source mapping |
+| [`src/types.ts`](src/types.ts) | Perplexity wire types for the chat-completions response |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; contracts are enforced at the service) |
+
+### Request and mapping flow
+
+`search()` posts the query with the model, token cap, and optional recency filter to `{baseURL}/chat/completions` with `redirect: 'error'`. The response's `content` becomes `content`; `search_results[]` becomes `sources[]` when present, otherwise each `citations[]` entry becomes a URL-only source; and the service applies the final `maxResults` bound on the way back. An abort — a `DOMException` named `AbortError` — becomes `WEB_ABORTED`; anything else becomes `WEB_PROVIDER_ERROR`.

+## 概述
 
-这是一个**实现**包：它向 `ctx.web` 注册提供方，不拥有该键，也不注册面向模型的工具。与 `@deepseek-ai/dsh-llm-deepseek` 一样，它是函数／命名空间插件（`inject: ['web']`）。OpenAI 兼容协议格式（wire format）是提供方私有细节，并**不**使该提供方依赖 `ctx.llm`。
+有了 `dsh-web-search-perplexity`，harness 可以通过 Perplexity 搜索 web，一次调用同时获得模型生成的答案与可引用来源。当部署持有 Perplexity API 密钥、并希望获得生成答案时选择它。Perplexity 没有结果数量控制，因此返回的来源会在事后被截断到请求的上限。Perplexity 省略结构化结果元数据时，来源回退为只含 URL 的引用。面向模型的 `web_search` 工具位于 `dsh-tool-web`。

+该提供方是 Perplexity chat-completions 端点之上的薄适配器，遵循两条刻意的规则：
+
+- **生成答案作为 `content` 受到信任。** 与其他搜索后端不同，Perplexity 返回模型生成的答案，本提供方将其作为规范化 `content` 字段透传。
+- **结构化来源优先；只含 URL 的引用是回退。** `search_results[]` 携带可移植字段；`citations[]` 只携带 URL，服务词汇把这些字段设为可选，正是为了这种情况。

 # @deepseek-ai/dsh-web
 
 English | [中文](README.zh.md)
 
-The **`WebRuntime`** (`ctx.web`) defines WHAT web access the harness has — search the web, fetch a URL — over multiple providers, without binding the model contract to one vendor's API shape.
+## Summary
 
-This package owns the Service Definition role of the web capability. Unlike shell/fs it spans two operations (search and fetch) on one seam, with potentially multiple providers each:
+Any plugin or tool can search the web or fetch a URL through `dsh-web` (`ctx.web`) without binding to any vendor's API. Search and fetch providers plug in as backends, and the service picks one usable provider per operation, so callers never track which vendor runs behind a call. Choose it when building web tooling or another backend; the shipped model-facing tools (`dsh-tool-web`) mount it automatically. The service itself makes no network calls and registers no model-facing tool: a provider must be mounted before search or fetch can run. Search and fetch share one selection policy, one cancellation and error vocabulary, and one configuration surface, so "how this harness reaches the web" has a single owner.

+<a id="use-this-package"></a>
+## Use this package
+
+A composition that needs web access loads the `dsh-web` service and mounts at least one backend — a search provider and/or a fetch provider — and plugin or tool authors then call `ctx.web.search()` and `ctx.web.fetch()` directly. The service resolves the backend for each call, so callers never see provider ids unless they configured one.
+
+### When to choose it
+
+Choose the service when a plugin or tool must search or fetch without hard-coding a vendor; a deployment that only uses the shipped `web_search`/`web_fetch` tools gets it for free through `dsh-tool-web`. You do not need it when the composition never reaches the web. The service adds no network access of its own: without at least one usable provider, every call fails with a structured `WebError`.
+
+### Minimal configuration
+
+Load the service and let a single mounted backend auto-select, or pin a provider id with `searchProvider`/`fetchProvider`. The environment variables `$DSH_WEB_SEARCH_PROVIDER` and `$DSH_WEB_FETCH_PROVIDER` feed the same fields and are not a separate priority chain.
+
+```yaml
+- name: '@deepseek-ai/dsh-web'
+- name: '@deepseek-ai/dsh-web-search-exa'
+- name: '@deepseek-ai/dsh-web-fetch-http'
+```
+
+| Field | Default | Meaning |
+|---|---|---|
+| `searchProvider` | (unset) | Pinned search provider id; unset auto-selects when exactly one is usable |
+| `fetchProvider` | (unset) | Pinned fetch provider id; unset auto-selects when exactly one is usable |
+
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-web) is the exhaustive source for every accepted field and its JSDoc.
+
+### Searching and fetching
+
+`search()` runs one query and returns an optional provider answer plus a list of citeable sources; the service enforces `request.maxResults` by truncating `sources[]` and setting `truncated`. `fetch()` retrieves one URL and returns its final URL, status code, decoded body, and a truncation flag; a non-2xx response is a result, not an error.
+
+```text
+// Search the web; sources[] is capped to maxResults:
+const result = await ctx.web.search({ query: 'deepseek harness', maxResults: 8 })
+
+// Fetch one URL; a non-2xx response is a result, not an error:
+const page = await ctx.web.fetch({ url: 'https://example.com' })
+```
+
+Both calls accept an optional `AbortSignal` that is forwarded to the provider for cancellation. The normalized request and result shapes are the contract callers build on; the vocabulary section of the [web subsystem](../../../docs/subsystems/web.md) reference describes them exhaustively.
+
+### Provider selection
+
+Each call resolves its provider at execution time, and registration or load order never matters. A configured provider id wins when it is registered and usable; without a configured id, the service runs the single usable provider or fails clearly:
+
+| Situation | Outcome |
 |---|---|
-| `@deepseek-ai/dsh-web` (this) | Service Definition: the service, provider registries, selection policy, request/result vocabulary, the `WebError` taxonomy |
-| `@deepseek-ai/dsh-web-search-exa` | Search provider: Exa |
-| `@deepseek-ai/dsh-web-search-perplexity` | Search provider: Perplexity |
-| `@deepseek-ai/dsh-web-fetch-http` | Fetch provider: anonymous public HTTP(S) |
-| `@deepseek-ai/dsh-tool-web` | Consumer: the model-facing `web_search` / `web_fetch` tool schemas over `ctx.web` |
-
-Search and fetch share no request schema and no business logic, but they are deliberately one seam: `ctx.web` is a single web-access middle layer with one provider-selection policy owner, one abort/error vocabulary, and one product-facing "how this harness reaches the web" config surface. The `Search`/`Fetch` method pairs are deliberately parallel.
-
-## Service API (`ctx.web`)
-
-| Member | Semantics |
-|---|---|
-| `registerSearchProvider(provider)` / `registerFetchProvider(provider)` | Register a backend. Throws `WebError` `WEB_DUPLICATE_PROVIDER` on a duplicate id within that capability kind. Returns a disposer. Disposed with the calling fiber. |
-| `search(request, signal?)` | Resolve the search provider and run one search. Enforces `request.maxResults` on the result (truncates `sources[]`, sets `truncated`). Throws `WebError` when the capability cannot run. |
-| `fetch(request, signal?)` | Resolve the fetch provider and retrieve one URL. A non-2xx response is a result, not a throw. Throws `WebError` for failures to safely retrieve or represent the resource. |
-
-Providers register **capabilities**, not tools. `dsh-tool-web` is the only owner of model-facing names, descriptions, prompt guidance, JSON schemas, and presentation.
-
-## Selection
-
-Selection never depends on registration, config, or HMR order. A capability has an explicit provider id (config `searchProvider`/`fetchProvider`, or env `$DSH_WEB_SEARCH_PROVIDER`/`$DSH_WEB_FETCH_PROVIDER` feeding the same fields), or auto-selects when exactly one usable provider is registered. `search()`/`fetch()` resolve the provider at execution time:
-
-| Situation | Execution |
-|---|---|
-| configured id registered and `available()` | runs that provider |
+| configured id registered and usable | runs that provider |
 | configured id not registered | `WEB_PROVIDER_CONFIGURED_MISSING` |
 | configured id registered but unavailable | `WEB_PROVIDER_CONFIGURED_UNAVAILABLE` |
 | no id, exactly one registered usable provider | runs it |
 | no id, no usable provider | `WEB_PROVIDER_UNAVAILABLE` |
 | no id, multiple usable providers | `WEB_PROVIDER_AMBIGUOUS` |
 
-The failure branches throw `WebError`, whose structured code (plus message detail — the missing id, the ambiguous candidate set) is the direct callers route on. A provider's own `available()` is a cheap local check (credential presence, parseable config) that feeds this execution-time selection and **must not make network calls**; `dsh-tool-web` never calls it — the tool executes through `ctx.web.search()`/`fetch()` and routes on the thrown codes, so provider selection has one owner.
+A provider's availability is a cheap local check — for example whether its API key is present — and never makes network calls, so selection stays fast and deterministic.
 
-## Vocabulary
+### Failures and recovery
 
-`WebSearchRequest` (`query`, `maxResults?`) → `WebSearchResult` (`content?`, `sources[]`, `truncated`); each `WebSearchSource` has a required `url` and optional `title`/`snippet`/`publishedAt` (Perplexity citations may be URL-only). `WebFetchRequest` (`url`) → `WebFetchResult` (final `url`, `statusCode`, `body`, `truncated`); cancellation is a direct optional `AbortSignal` argument to `search()`/`fetch()`. `WebFetchBody` is a CLOSED discriminated union (`html` | `text`) owned here — consumers `switch` to exhaustiveness so a new kind breaks their compilation until handled. See `src/types.ts` for the full contracts and the `WebError` code taxonomy.
+Failures throw `WebError` with a stable, machine-routable code; the message adds detail such as the missing provider id or the ambiguous candidate set. Callers route on the code and decide how to degrade. To change which backend a call uses, reconfigure the pinned id, mount or unmount providers, or fix the provider's configuration so its availability check passes.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the service; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+The package is built on one deliberate separation:
+
+- **One seam, two independent operations.** Search and fetch share no request schema and no business logic, but they share one service so provider selection, cancellation, errors, and product configuration have a single owner. The parallel `Search`/`Fetch` method pairs are intentional.
+- **Selection is never order-dependent.** A capability either pins a provider id or auto-selects when exactly one usable provider is registered; `search()`/`fetch()` resolve the provider at execution time.
+- **The service owns the result bound.** `maxResults` is enforced by the seam after the provider returns, so an over-returning provider can never leak more sources than the caller asked for.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: the `WebRuntime` service, both provider registries, and execution-time selection |
+| [`src/types.ts`](src/types.ts) | Vocabulary: request/result types, the closed `WebFetchBody` union, and the `WebError` taxonomy |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; contracts are enforced at the service) |
+
+### Data model
+
+The request and result types define the normalized vocabulary callers build on — one `Search` pair and one `Fetch` pair — and the exhaustive fields and JSDoc live in [`src/types.ts`](src/types.ts) and the [web subsystem](../../../docs/subsystems/web.md) reference. Two deliberate choices shape them: `WebFetchBody` is a closed union (`html` | `text`) owned here, so adding a kind breaks compilation until every consumer handles it; `WebError` extends `HarnessError` with an open-string `code`, so consumers must tolerate provider-specific values. Source fields stay optional because not every provider returns all of them.
+
+### Selection flow
+
+At call time the service resolves the provider — configured id first, then the unique usable provider — and throws the matching `WebError` when no clear winner exists. A search result then passes through `capSources`, which truncates `sources[]` to `maxResults` and flags `truncated`. Registration is effect-based: providers register with the calling fiber and unregister when it disposes, and a duplicate id within a capability kind is rejected at registration.

-**`WebRuntime`**（`ctx.web`）定义 harness 具备哪些 web 访问能力（搜索 web、抓取 URL），并通过多个提供方实现，不把模型约定绑定到某个厂商的 API 形状。
+## 概述
 
-本包承担 web 能力的 Service Definition 角色。与 shell/fs 不同，它在一个 seam 上跨越搜索与抓取两种操作，每种操作都可能有多个提供方：
+任何插件或工具都可以通过 `dsh-web`（`ctx.web`）搜索 web 或抓取 URL，而无需绑定任何厂商的 API。搜索与抓取提供方以后端形式接入，服务按操作挑选一个可用的提供方，调用方无需追踪每次调用背后是哪家厂商。在构建 web 工具或其他后端时选择它；已交付的面向模型工具（`dsh-tool-web`）会自动挂载它。服务本身不发起网络调用、不注册面向模型的工具：搜索或抓取执行前必须已挂载提供方。搜索与抓取共用同一套选择策略、取消与错误词汇以及配置接口，因此「这个 harness 如何访问 web」只有一个归属方。

+## 使用本包
+
+需要 web 访问的组合会加载 `dsh-web` 服务并挂载至少一个后端——搜索提供方和／或抓取提供方——插件或工具作者随后直接调用 `ctx.web.search()` 与 `ctx.web.fetch()`。服务会为每次调用解析后端，因此除非调用方配置了提供方 id，否则它们看不到提供方 id。
+
+### 何时选择
+
+当插件或工具必须搜索或抓取、又不希望硬编码厂商时选择本服务；只使用已交付的 `web_search`／`web_fetch` 工具的组合会通过 `dsh-tool-web` 免费获得它。当组合从不访问 web 时，你不需要它。服务本身不增加任何网络访问能力：没有至少一个可用提供方时，每次调用都会以结构化 `WebError` 失败。
+
+### 最小配置
+
+加载服务并让唯一挂载的后端自动选择，或用 `searchProvider`／`fetchProvider` 固定提供方 id。环境变量 `$DSH_WEB_SEARCH_PROVIDER` 与 `$DSH_WEB_FETCH_PROVIDER` 提供相同字段，不是另一条优先级链。
+
+```yaml
+- name: '@deepseek-ai/dsh-web'
+- name: '@deepseek-ai/dsh-web-search-exa'
+- name: '@deepseek-ai/dsh-web-fetch-http'
+```
+
+| 字段 | 默认值 | 含义 |
+|---|---|---|
+| `searchProvider` | （未设置） | 固定的搜索提供方 id；未设置时仅在恰好一个可用时自动选择 |
+| `fetchProvider` | （未设置） | 固定的抓取提供方 id；未设置时仅在恰好一个可用时自动选择 |
+
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-web)是每个受支持字段及其 JSDoc 的穷尽式真源。
+
+### 搜索与抓取
+
+`search()` 执行一次查询，返回可选的提供方答案与可引用的来源列表；服务强制执行 `request.maxResults`：截断 `sources[]` 并设置 `truncated`。`fetch()` 获取一个 URL，返回其最终 URL、状态码、解码后的正文与截断标志；非 2xx 响应是结果，不是错误。
+
+```text
+// Search the web; sources[] is capped to maxResults:
+const result = await ctx.web.search({ query: 'deepseek harness', maxResults: 8 })
+
+// Fetch one URL; a non-2xx response is a result, not an error:
+const page = await ctx.web.fetch({ url: 'https://example.com' })
+```
+
+两个调用都接受可选的 `AbortSignal`，用于把取消转发给提供方。规范化的请求与结果形状是调用方赖以构建的约定；[web 子系统](../../../docs/subsystems/web.zh.md) 参考中的词汇章节对其有穷尽式描述。
+
+### 提供方选择
+
+每次调用都在执行时解析提供方，注册或加载顺序从不影响结果。已配置的提供方 id 在已注册且可用时优先；没有配置 id 时，服务运行唯一可用的提供方，或在情况不明时明确失败：
+
+| 情况 | 结果 |
 |---|---|
-| `@deepseek-ai/dsh-web`（本包） | Service Definition：服务、提供方注册表、选择策略、请求／结果词汇、`WebError` 分类体系 |
-| `@deepseek-ai/dsh-web-search-exa` | 搜索提供方：Exa |
-| `@deepseek-ai/dsh-web-search-perplexity` | 搜索提供方：Perplexity |
-| `@deepseek-ai/dsh-web-fetch-http` | 抓取提供方：匿名公共 HTTP(S) |
-| `@deepseek-ai/dsh-tool-web` | Consumer：面向模型的 `web_search`／`web_fetch` 工具 schema，构建于 `ctx.web` 之上 |
-
-搜索与抓取没有共享请求 schema 或业务逻辑，但有意共用一个 seam：`ctx.web` 是单一 web 访问中间层，拥有一项提供方选择策略、一套中止／错误词汇和一个面向产品的「该 harness 如何访问 web」配置接口。成对的 `Search`／`Fetch` 方法保持并行是有意为之。
-
-## 服务 API（`ctx.web`）
-
-| 成员 | 语义 |
-|---|---|
-| `registerSearchProvider(provider)`／`registerFetchProvider(provider)` | 注册后端。同一能力类型下 id 重复时抛出 `WebError` `WEB_DUPLICATE_PROVIDER`。返回 disposer。随调用 fiber 一并 dispose（资源释放）。 |
-| `search(request, signal?)` | 解析搜索提供方并运行一次搜索。在结果上强制执行 `request.maxResults`（截断 `sources[]`，设置 `truncated`）。能力无法运行时抛出 `WebError`。 |
-| `fetch(request, signal?)` | 解析抓取提供方并获取一个 URL。非 2xx 响应是结果，不会抛出异常。无法安全获取或表示资源时抛出 `WebError`。 |
-
-提供方注册的是**能力**而非工具。`dsh-tool-web` 是面向模型的名称、描述、提示词指引、JSON Schema 和呈现的唯一归属方。
-
-## 选择
-
-选择绝不依赖注册、配置或 HMR（热模块替换）顺序。能力要么具有显式提供方 id（配置 `searchProvider`／`fetchProvider`，或由环境变量 `$DSH_WEB_SEARCH_PROVIDER`／`$DSH_WEB_FETCH_PROVIDER` 提供相同字段），要么在恰好只注册一个可用提供方时自动选择。`search()`／`fetch()` 会在执行时解析提供方：
-
-| 情况 | 执行 |
-|---|---|
-| 已配置 id 已注册且 `available()` | 运行该提供方 |
+| 已配置 id 已注册且可用 | 运行该提供方 |
 | 已配置 id 未注册 | `WEB_PROVIDER_CONFIGURED_MISSING` |
 | 已配置 id 已注册但不可用 | `WEB_PROVIDER_CONFIGURED_UNAVAILABLE` |
-| 无 id，恰好一个已注册的可用提供方 | 运行该提供方 |
+| 无 id，恰好一个已注册的可用提供方 | 运行它 |
 | 无 id，没有可用提供方 | `WEB_PROVIDER_UNAVAILABLE` |
 | 无 id，多个可用提供方 | `WEB_PROVIDER_AMBIGUOUS` |
 
-失败分支会抛出 `WebError`；调用方按其结构化 code（加消息细节：缺失 id、歧义候选集合）路由。提供方自身的 `available()` 是便宜的局部检查（凭据是否存在、配置是否可解析），供执行时选择使用，且**禁止发起网络调用**；`dsh-tool-web` 永远不会调用它。工具通过 `ctx.web.search()`／`fetch()` 执行，并按抛出的 code 路由，因此提供方选择只有一个归属方。
+提供方的可用性是一项廉价的局部检查——例如其 API 密钥是否存在——并且从不发起网络调用，因此选择保持快速且确定。
 
-## 词汇
+### 失败与恢复
 
-`WebSearchRequest`（`query`、`maxResults?`）→ `WebSearchResult`（`content?`、`sources[]`、`truncated`）；每个 `WebSearchSource` 都有必填 `url` 与可选 `title`／`snippet`／`publishedAt`（Perplexity 引用可能只含 URL）。`WebFetchRequest`（`url`）→ `WebFetchResult`（最终 `url`、`statusCode`、`body`、`truncated`）；取消作为可选的直接 `AbortSignal` 参数传给 `search()`／`fetch()`。`WebFetchBody` 是这里拥有的封闭判别联合（`html` | `text`）；消费方使用 `switch` 实现穷尽检查，因此新增类型会导致编译失败，直到处理完毕。完整约定见 `src/types.ts`，其中也包含 `WebError` code 分类体系。
+失败抛出 `WebError`，携带稳定、可按机器路由的 code；消息补充细节，例如缺失的提供方 id 或歧义候选集合。调用方按 code 路由并决定如何降级。要改变一次调用使用的后端，请重新配置固定的 id、挂载或卸载提供方，或修正提供方配置使其可用性检查通过。

+
+本节解释服务背后的设计决策；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+本包建立在一个刻意的分离之上：
+
+- **一个 seam，两个独立操作。** 搜索与抓取没有共享请求 schema 或业务逻辑，但它们共用一个服务，使提供方选择、取消、错误与产品配置只有一个归属方。并行的 `Search`／`Fetch` 方法对是有意为之。
+- **选择绝不依赖顺序。** 能力要么固定提供方 id，要么在恰好注册一个可用提供方时自动选择；`search()`／`fetch()` 在执行时解析提供方。
+- **服务拥有结果上限。** `maxResults` 由 seam 在提供方返回后强制执行，因此超量返回的提供方绝不可能泄漏超出调用方要求的来源。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：`WebRuntime` 服务、两个提供方注册表与执行时选择 |
+| [`src/types.ts`](src/types.ts) | 词汇：请求／结果类型、封闭的 `WebFetchBody` 联合与 `WebError` 分类体系 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；约定在服务处强制执行） |
+
+### 数据模型
+
+请求与结果类型定义了调用方赖以构建的规范化词汇——一组 `Search` 对与一组 `Fetch` 对——穷尽式字段与 JSDoc 见 [`src/types.ts`](src/types.ts) 与 [web 子系统](../../../docs/subsystems/web.zh.md) 参考。两个刻意的选择塑造了它们：`WebFetchBody` 是这里拥有的封闭联合（`html` | `text`），因此新增类型会破坏编译，直到每个消费方都处理它；`WebError` 继承 `HarnessError`，携带开放的字符串 `code`，因此消费方必须容忍提供方专有的取值。来源字段保持可选，因为并非每个提供方都返回全部字段。
+
+### 选择流程
+
+执行时，服务先按配置 id、再按唯一可用提供方解析提供方，没有明确赢家时抛出对应的 `WebError`。搜索结果随后经过 `capSources`：把 `sources[]` 截断到 `maxResults` 并标记 `truncated`。注册基于 effect：提供方随调用 fiber 注册，fiber 释放时注销；同一能力类型下重复的 id 会在注册时被拒绝。

-This family runs model-authored orchestration workflows over subagents and exposes general and fixed-policy tools to the model.
+## Summary
+
+The workflow group lets an agent run a model-authored orchestration script that fans work out across many subagents and returns a final value. The `workflow` package provides the run service, the worker-thread package executes scripts in isolated threads, and two model-facing tools expose orchestration: the general `workflow` tool for scripted fan-out and the fixed `ralph` tool for fresh-agent iterative loops. The script coordinates agents with hooks while the agents do the actual work. The engine keeps a script's synchronous work off the host event loop but is containment, not a security boundary.

+## 概述
+
+workflow 组让 agent 可以运行一段由模型编写的编排脚本，把工作扇出到多个 subagent 并返回最终值。`workflow` 包提供运行服务，worker-thread 包在隔离线程中执行脚本，两个面向模型的工具公开编排能力：通用的 `workflow` 工具用于脚本化扇出，固定的 `ralph` 工具用于全新 agent 迭代循环。脚本用钩子协调 agent，实际工作由 agent 完成。引擎把脚本的同步工作移出宿主事件循环，但这只是隔离，不是安全边界。

 # @deepseek-ai/dsh-tool-ralph
 
 English | [中文](README.zh.md)
 
-The model-facing `ralph` tool runs a fixed foreground workflow that gives one immutable objective to a sequence of fresh child agents. It demonstrates a specialized orchestration policy as an ordinary plugin over [`ctx.workflowEngine`](../workflow/README.md) and [`ctx.subagents`](../../subagent/subagent/README.md): no Ralph mode or fresh-agent loop is added to `agent-loop`, and the same-session [goal domain](../../goal/goal/README.md) remains independent. The [Ralph Agent Note](../../../.agents/notes/implemented/feature/2026-07-19-fresh-agent-ralph-workflow-tool.md) owns the policy and deferred work.
+## Summary
 
-## Contract
+`dsh-tool-ralph` gives the model the `ralph` tool: a fixed foreground workflow that hands one immutable objective to a sequence of fresh child agents, each starting with no conversation seed and carrying only the previous bounded report. It is a specialized orchestration policy built on the workflow and subagent capabilities — no Ralph mode is added to the agent loop, and the same-session goal domain stays independent. The call returns when a worker reports completion or a concrete blocker, or at the round limit; completion and blockers are worker reports, not independent certification. Use it only when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution; ordinary long-running objectives belong to goal tools, and bounded delegation belongs to subagents or workflows.
 
-`ralph({ objective, maxRounds? })` waits for the entire run. The deployment config's `maxRounds` is both the default and a ceiling on a call override. Every Ralph round starts one child through `subagentProvider`; that provider must exist, support structured output, and report `inheritsParentContext: false`. The configured provider is carried as `WorkflowStartRequest.subagentProvider`, so the fixed script cannot inspect or change routing and the ordinary model-written `workflow` tool gains no provider selector. The resolved round cap is also carried as `WorkflowStartRequest.maxTotalAgents`, coordinating the fixed loop with the engine's total-child backstop; the engine rejects a Ralph cap above its deployment ceiling before publishing a run.
+## Table of Contents
 
-Each child receives only the immutable objective, its current Ralph round and cap, a shared-workspace-as-authority instruction, and the previous structured handoff. The workspace is long-term memory; parent conversation and prior child sessions are not seeded. Reports have `status: continue | complete | blocked`, a non-empty summary, evidence, next steps, and blocker text. Status-specific semantics and the serialized `maxHandoffChars` ceiling are validated inside the fixed workflow and again at the consumer boundary. Invalid, missing, or oversized reports fail the workflow instead of being truncated or mistaken for cap exhaustion.

+- [Further Exploration](#further-exploration)
+- [Model Experience](#model-experience)
+- [Known Limitations and Deferred Work](#known-limitations-and-deferred-work)
+- [Dev Note](#dev-note)
 
-The successful terminal tool result is `complete`, `blocked`, or `budget-limited`, with the last bounded report and number of rounds started. The canonical envelope is `{ runId, agentsStarted, result }`; completion and blocker labels in its Native renderer explicitly say that a worker reported the outcome, not independent certification. `maxResultChars` bounds only that rendered text including its truncation marker, without altering the validated report in the canonical value or the cross-round handoff.
+-----
 
-An ordinary child failure produces an error naming the failed round and retaining the last successful handoff when one exists. Ralph does not retry that round. Fatal provider-start, transport, worker, or workflow failures remain workflow errors and may settle before the fixed script can return a handoff. Cancellation is also an error; partial output is never success.
+<a id="use-this-package"></a>
+## Use this package
 
-## Lifecycle and cancellation
+The `ralph` tool runs a fixed foreground loop: one fresh child per round works on the immutable objective in the shared workspace, and only a bounded structured report crosses rounds. Use it only when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. For ordinary long-running same-session work, use goal tools; for bounded delegation and fan-out, use plain subagents or the `workflow` tool.
 
-The caller's agent is the parent of every fresh child, preserving cwd and lineage without copying its conversation. `exec.signal` enters the workflow engine and is also bridged to `run.cancel()` for implementation independence. The tool awaits `run.result` and calls `run.dispose()` in `finally`, so a cancelled parent step waits for the engine's bounded termination and child quiescence before returning.
+### Calling the tool
 
-## Render intent
+The model submits `{ objective, maxRounds? }` and the call blocks until the whole run settles. The deployment config's `maxRounds` is both the default and a ceiling on a call override. The terminal result is `complete`, `blocked`, or `budget-limited`, carrying the last bounded report and the number of rounds started; an ordinary child failure returns an error naming the failed round and retaining the last successful handoff when one exists.
 
-The pending call is a `generic` card titled `ralph`; the immutable objective is its `rawInput`. The result keeps the generic card. Both presentation functions depend only on tool arguments and the settled tool envelope.
+### What each round sees
 
-## Config
+Each child receives only the immutable objective, its current round and cap, a shared-workspace-as-authority instruction, and the previous structured handoff; parent conversation and prior child sessions are never seeded. The workspace is the long-term memory across rounds. Reports carry a status (`continue`, `complete`, or `blocked`), a non-empty summary, evidence, next steps, and blocker text; invalid or oversized reports fail the workflow instead of being truncated or mistaken for cap exhaustion.
 
-| Key | Default | Meaning |
+### Config
+
+| Field | Default | Meaning |
 |---|---|---|
 | `subagentProvider` | `spawn` | Fresh structured-output provider used for every round. |
 | `maxRounds` | `256` | Default and deployment ceiling for one Ralph run. |
 | `maxHandoffChars` | `16384` | Maximum serialized characters in one round report. |
 | `maxResultChars` | `16384` | Maximum characters in the complete successful parent result. |
 
-All config values are normalized and validated when the plugin applies, including direct application outside Loader schema normalization. Provider capabilities are resolved immediately before each call because provider registration can change under plugin lifecycle and HMR.
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-tool-ralph) is the exhaustive source for every accepted field. The configured provider must exist, support structured output, and report `inheritsParentContext: false`; a call against a provider that violates this fails loud before any round starts.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the fixed-script design and the validation and lifecycle mechanics; observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The loop is a deployment-owned fixed script: the model supplies data only and cannot alter the loop, provider route, schema, or handoff validation. The tool is an ordinary plugin over `ctx.workflowEngine` and `ctx.subagents` — no Ralph mode or fresh-agent loop is added to `agent-loop`, and the same-session goal domain stays independent. The [Ralph Agent Note](../../../.agents/notes/implemented/feature/2026-07-19-fresh-agent-ralph-workflow-tool.md) owns the policy and deferred work.
+
+### Fixed script and routing
+
+The configured provider is carried as `WorkflowStartRequest.subagentProvider`, so the fixed script cannot inspect or change routing and the ordinary model-written `workflow` tool gains no provider selector. The resolved round cap is carried as `WorkflowStartRequest.maxTotalAgents`, coordinating the fixed loop with the engine's total-child backstop; the engine rejects a cap above its deployment ceiling before publishing a run.
+
+### Report validation
+
+Status-specific semantics and the serialized `maxHandoffChars` ceiling are validated inside the fixed workflow and again at the consumer boundary: a continuing report needs next steps and an empty blocker, a completion report needs evidence and no next steps, and a blocked report needs a concrete blocker. Invalid, missing, or oversized reports fail the workflow.
+
+### Lifecycle and cancellation
+
+The caller's agent is the parent of every fresh child, preserving cwd and lineage without copying its conversation. `exec.signal` enters the workflow engine and is also bridged to `run.cancel()` for implementation independence. The tool awaits `run.result` and calls `run.dispose()` in `finally`, so a cancelled parent step waits for the engine's bounded termination and child quiescence before returning.
+
+### Render intent
+
+The pending call is a `generic` card titled `ralph` with the immutable objective as its `rawInput`; the result keeps the generic card. Both presentation functions depend only on tool arguments and the settled tool envelope, and the completion and blocker labels state that a worker reported the outcome, not independent certification.

+| [`src/index.ts`](src/index.ts) | Plugin entry: fixed script, provider routing, report validation, tool registration |

-面向模型的 `ralph` 工具运行固定的前台工作流，把一个不可变目标依次交给多个全新子 agent（智能体）。它展示如何把专用编排策略实现为基于 [`ctx.workflowEngine`](../workflow/README.zh.md) 和 [`ctx.subagents`](../../subagent/subagent/README.zh.md) 的普通插件：不会向 `agent-loop` 添加 Ralph 模式或全新 agent loop（智能体循环），同会话的[目标领域](../../goal/goal/README.zh.md)也保持独立。策略和暂缓事项由 [Ralph Agent Note（agent 决策记录）](../../../.agents/notes/implemented/feature/2026-07-19-fresh-agent-ralph-workflow-tool.zh.md)负责。
+## 概述
 
-## 契约
+`dsh-tool-ralph` 把 `ralph` 工具交给模型：一个固定的前台工作流，把一个不可变目标依次交给多个全新子 agent（智能体），每个子 agent 都没有对话种子，只携带上一份有界报告。它是构建在工作流与 subagent 能力之上的专用编排策略——不会向 agent loop 添加 Ralph 模式，同会话的 goal 领域也保持独立。调用在 worker 报告完成或具体阻塞、或达到 Round 上限时返回；完成与阻塞都是 worker 报告，不是独立认证。仅当直接用户明确要求 Ralph 循环或全新 agent 迭代执行时使用它；普通的长期同会话目标属于 goal 工具，有界委派属于 subagent 或工作流。
 
-`ralph({ objective, maxRounds? })` 会等待整个运行完成。部署配置中的 `maxRounds` 既是默认值，也是调用覆盖值的上限。每个 Ralph Round 通过 `subagentProvider` 启动一个子 agent；该提供方必须存在、支持结构化输出，并报告 `inheritsParentContext: false`。已配置的提供方以 `WorkflowStartRequest.subagentProvider` 传递，使固定脚本无法检查或更改路由，普通的模型编写 `workflow` 工具也不会因此获得提供方选择器。解析后的 Round 上限还会作为 `WorkflowStartRequest.maxTotalAgents` 传递，使固定循环与引擎的子 agent 总数后备上限协同；Ralph 上限超过引擎部署上限时，引擎会在发布运行前拒绝。
+## 目录
 
-每个子 agent 只接收不可变目标、当前 Ralph Round 及其上限、一条「共享工作区是权威状态」指令，以及上一个结构化交接内容。工作区是长期记忆；不会把父级对话或先前子 agent 会话作为初始内容。报告包含 `status: continue | complete | blocked`、非空摘要、证据、后续步骤和阻塞文本。固定工作流内部及消费方边界都会校验特定状态的语义和序列化后的 `maxHandoffChars` 上限。无效、缺失或过大的报告会使工作流失败，而不会被截断或误认为上限耗尽。

-成功的终态工具结果为 `complete`、`blocked` 或 `budget-limited`，并包含最后一份有界报告和已启动的 Round 数量。规范包络为 `{ runId, agentsStarted, result }`；Native 渲染器中的完成与阻塞标签会明确说明结果由 worker 报告，而非独立认证。`maxResultChars` 只限制包含截断标记的渲染文本，不会改变规范值中经过校验的报告或跨 Round 交接内容。
+-----
 
-普通子 agent 失败会产生错误，其中标明失败的 Round；如果已有上一次成功交接，也会保留它。Ralph 不会重试该 Round。致命的提供方启动、传输、worker 或工作流失败仍是工作流错误，并可能在固定脚本返回交接内容前结算。取消同样属于错误；局部输出绝不会视为成功。
+<a id="use-this-package"></a>
+## 使用本包
 
-## 生命周期与取消
+`ralph` 工具运行固定的前台循环：每个 Round 一个全新子 agent 在共享工作区中处理不可变目标，只有一份有界的结构化报告跨越 Round。仅当直接用户明确要求 Ralph 循环或全新 agent 迭代执行时使用它。普通的长期同会话工作请使用 goal 工具；有界委派与扇出请使用普通 subagent 或 `workflow` 工具。
 
-调用方 agent 是每个全新子 agent 的父级，因此会保留 cwd 和谱系，但不会复制其对话。`exec.signal` 进入工作流引擎，同时也桥接到 `run.cancel()`，以便不依赖具体实现。工具等待 `run.result` 并调用 `run.dispose()`，后一个调用位于 `finally` 中，因此取消的父级步骤会等到引擎完成有界终止且子 agent 完全停稳后才返回。
+### 调用工具
 
-## 渲染意图
+模型提交 `{ objective, maxRounds? }`，调用会阻塞到整个运行结算。部署配置中的 `maxRounds` 既是默认值，也是调用覆盖值的上限。终态结果为 `complete`、`blocked` 或 `budget-limited`，携带最后一份有界报告与已启动的 Round 数量；普通子 agent 失败会返回错误，其中标明失败的 Round，并在存在时保留上一次成功交接。
 
-待处理调用使用 `generic` 卡片，标题为 `ralph`；不可变目标作为其 `rawInput`。结果继续使用 generic 卡片。两个呈现函数都只依赖工具参数和已结算的工具包络。
+### 每个 Round 看到什么
 
-## 配置
+每个子 agent 只接收不可变目标、当前 Round 及其上限、一条「共享工作区是权威状态」指令与上一份结构化交接；父级对话与先前子 agent 会话绝不会作为种子。工作区是跨 Round 的长期记忆。报告携带状态（`continue`、`complete` 或 `blocked`）、非空摘要、证据、后续步骤与阻塞文本；无效或过大的报告会使工作流失败，而不会被截断或误认为上限耗尽。
 
-| 键 | 默认值 | 含义 |
+### 配置
+
+| 字段 | 默认值 | 含义 |
 |---|---|---|
 | `subagentProvider` | `spawn` | 每个 Round 使用的全新结构化输出提供方。 |
 | `maxRounds` | `256` | 一次 Ralph 运行的默认值和部署上限。 |
 | `maxHandoffChars` | `16384` | 一份 Round 报告序列化后的最大字符数。 |
 | `maxResultChars` | `16384` | 返回给父级的完整成功结果最大字符数。 |
 
-插件应用时会规范化并校验所有配置值，也包括绕过 Loader schema 规范化而直接应用的情况。每次调用前都会立即解析提供方能力，因为提供方注册可能随插件生命周期和热模块替换（HMR）变化。
+生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-tool-ralph)是每个受支持字段的穷尽式真源。配置的提供方必须存在、支持结构化输出，并报告 `inheritsParentContext: false`；针对违反此要求的提供方的调用会在任何 Round 开始前响亮失败。

+循环是部署方拥有的固定脚本：模型只提供数据，无法改变循环、提供方路由、schema 或交接校验。该工具是基于 `ctx.workflowEngine` 与 `ctx.subagents` 的普通插件——不会向 `agent-loop` 添加 Ralph 模式或全新 agent loop，同会话的 goal 领域也保持独立。[Ralph Agent Note](../../../.agents/notes/implemented/feature/2026-07-19-fresh-agent-ralph-workflow-tool.zh.md)拥有策略与暂缓事项。
+
+### 固定脚本与路由
+
+配置的提供方以 `WorkflowStartRequest.subagentProvider` 传递，因此固定脚本无法检查或更改路由，普通的模型编写 `workflow` 工具也不会因此获得提供方选择器。解析后的 Round 上限以 `WorkflowStartRequest.maxTotalAgents` 传递，使固定循环与引擎的子 agent 总数后备上限协同；上限超过引擎部署上限时，引擎会在发布运行前拒绝。
+
+### 报告校验
+
+特定状态的语义与序列化后的 `maxHandoffChars` 上限会在固定工作流内部及消费方边界各校验一次：继续报告需要后续步骤与空阻塞，完成报告需要证据且没有后续步骤，阻塞报告需要具体阻塞。无效、缺失或过大的报告会使工作流失败。
+
+### 生命周期与取消
+
+调用方 agent 是每个全新子 agent 的父级，因此会保留 cwd 与谱系，但不会复制其对话。`exec.signal` 进入工作流引擎，同时也桥接到 `run.cancel()`，以便不依赖具体实现。工具等待 `run.result` 并在 `finally` 中调用 `run.dispose()`，因此被取消的父级步骤会等到引擎完成有界终止且子 agent 完全停稳后才返回。
+
+### 渲染意图
+
+待处理调用使用 `generic` 卡片，标题为 `ralph`，不可变目标作为其 `rawInput`；结果继续使用 generic 卡片。两个呈现函数都只依赖工具参数与已结算的工具包络，完成与阻塞标签会说明结果由 worker 报告，而非独立认证。

 # @deepseek-ai/dsh-tool-workflow
 
 English | [中文](README.zh.md)
 
-The model-facing **`workflow` tool**: run a JavaScript orchestration script that fans out subagents, and return the script's final value. This package owns the model-facing schema and run lifecycle over [`ctx.workflowEngine`](../workflow/README.md); script parsing, execution, caps, and cancellation live behind the seam, while the consumer retains ownership of the parent-facing schema and result envelope.
+## Summary
 
-## What the model sees
+`dsh-tool-workflow` gives the model the `workflow` tool: call it with a JavaScript orchestration script, an identity block, and optional arguments, and it runs the script over `ctx.workflowEngine`, fanning work out across subagents until the script's final value returns. The tool owns the model-facing schema, the usage guidance in the system prompt, and the result envelope; script parsing, execution, caps, and cancellation live behind the engine. Execution is foreground: the parent turn blocks until the whole workflow settles, and a non-clean finish is an error, never partial output. Choose it when the user explicitly asks for workflow-style or large multi-agent orchestration; prefer plain subagent calls for one or two delegations.
 
-Three parameters: `meta` (required identity data: `name`, `description`, and optional progress annotations), `script` (required plain JavaScript body — no `export const meta` statement; the tool description carries the complete authoring contract), and `args` (optional JSON object exposed to the script as the `args` global; wrap a bare list in a field so the wire schema stays honest). The plugin also contributes a `tool:<toolName>` system-prompt section carrying the usage policy — use the tool only on an explicit user ask for a workflow / large orchestration; prefer plain subagent calls for one or two delegations — per the convention that tool guidance ships with the tool plugin, never in the deployment persona.

-Collection is synchronous (like [`dsh-tool-subagent`](../../subagent/tool-subagent/README.md)): `execute` starts a run and awaits `run.result` inside a `try/finally` that always disposes the run, so the script and its children reach quiescence on every path. `exec.signal` is bridged to `run.cancel()` (including the already-aborted-before-start case). A non-`completed` stop reason maps to an `isError` result reporting the reason—never partial output as success; a parse/meta failure thrown synchronously by `start()` becomes an `isError` the model can correct from. Completion returns canonical `{ runId, agentsStarted, result }`; the Native renderer preserves the meta name, agent count, and JSON value, truncating only that projection at `maxResultChars`.
+-----
 
-For a root transport execution (`exec.parent` absent), the tool also projects the run into the calling Agent's Session: run-start after `start()` returns, matching member starts and endings filtered by `run.id`, then run-end only after `run.result` is available and `dispose()` has reached quiescence. Nested transport calls execute normally but write no workflow record. The first failed Session append disables later recording for that run, emits one warning, and leaves either no record or a legal continuous prefix without changing the tool result or cleanup.
+<a id="use-this-package"></a>
+## Use this package
 
-The browser-safe `@deepseek-ai/dsh-tool-workflow/types` subpath owns these four log-only event payloads and their `SessionEventMap` declaration. The package invariant rejects duplicate starts, unpaired members, terminal events with open members, and updates after run-end on both cold load and live append while accepting missing terminal suffixes.
+The `workflow` tool runs a model-authored orchestration script that fans work out across many subagents and returns the script's final JSON value. Use it only when the user explicitly asks for a workflow or for large multi-agent orchestration — an audit over many files, a migration, multi-angle research; for one or two delegations, prefer plain subagent calls.
 
-## Render intent
+### Calling the tool
 
-Decided up front (per the [render-intent Agent Note](../../../.agents/notes/implemented/architecture/2026-07-02-tool-render-intent-union.md)): a `generic` card titled `workflow: <meta.name>`, read directly from `args.meta.name` (presentation is a pure function of args and does not ask the engine to parse); the script text rides as `rawInput`. The result keeps the generic card.
+The model submits three parameters: `meta` (required identity data: `name`, `description`, and optional `whenToUse` and `phases`), `script` (required plain JavaScript body — no `export const meta` statement; the tool description carries the complete authoring contract), and `args` (optional JSON object exposed to the script as the `args` global; wrap a bare list in a field so the wire schema stays honest).
 
-## Config
+Success returns the canonical envelope `{ runId, agentsStarted, result }`, rendered to the model as `workflow "<name>" completed (<count> agent<optional-s>).` followed by `Return value:` and the pretty-printed JSON. A workflow that cannot start — a script parse or meta validation failure — returns an error the model can correct from. Cancellation and execution failures return `Error: workflow run was cancelled` or `Error: workflow run failed: <error>`; partial output is never reported as success.
 
-| Key | Default | Meaning |
+### What to expect during a run
+
+While the script runs, the parent turn waits: the tool starts the run, awaits its result, and always disposes it, so the script and its children reach quiescence on every path — including cancellation, which is bridged from the parent step's abort signal. The model sees one final outcome, never intermediate child messages; the children's own work stays out of the parent conversation.
+
+### Config
+
+| Field | Default | Meaning |
 |---|---|---|
 | `toolName` | `workflow` | The model-facing tool name to register. |
 | `maxResultChars` | `50000` | Rendered-result ceiling; longer JSON is truncated with a notice. |
 
+The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-tool-workflow) is the exhaustive source for every accepted field.

+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the consumer is split from the engine and how the run lifecycle and records work; observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The consumer owns the model-facing schema, the `tool:<toolName>` system-prompt guidance, and the result envelope; script parsing, execution, caps, and cancellation live behind `ctx.workflowEngine`, so a hardened engine swaps in without changing what the model sees. Usage guidance ships with the tool plugin as a prompt section, never in the deployment persona.
+
+### Run lifecycle
+
+`execute` starts the run and awaits `run.result` inside a `try/finally` that always disposes the run. `exec.signal` is bridged to `run.cancel()`, including the already-aborted-before-start case. A non-`completed` stop reason maps to an `isError` result reporting the reason; completion renders `{ runId, agentsStarted, result }`, with the Native renderer truncating only that projection at `maxResultChars`.
+
+### Durable session records
+
+For a root transport execution (`exec.parent` absent), the tool projects the run into the calling Agent's Session with four log-only events: run-start after `start()` returns, member starts and endings filtered by `run.id`, then run-end only after the result is available and disposal reaches quiescence. Nested transport calls execute normally but write no record. The first failed Session append disables later recording for that run with one warning, leaving either no record or a legal continuous prefix without changing the tool result or cleanup. The package invariant rejects duplicate starts, unpaired members, terminal events with open members, and updates after run-end on both cold load and live append, while accepting missing terminal suffixes.

 [English](README.md) | 中文
 
-面向模型的 **`workflow` 工具**：运行一段扇出 subagent 的 JavaScript 编排脚本，并返回脚本的最终值。本包负责基于 [`ctx.workflowEngine`](../workflow/README.zh.md) 定义面向模型的 schema 和运行生命周期；脚本解析、执行、上限与取消位于 seam 之后，消费方仍负责面向父级的 schema 和结果包络。
+## 概述
 
-## 模型看到的内容
+`dsh-tool-workflow` 把 `workflow` 工具交给模型：以 JavaScript 编排脚本、身份块与可选参数调用它，它会在 `ctx.workflowEngine` 上运行脚本，把工作扇出到多个 subagent，直到脚本的最终值返回。该工具拥有模型侧 schema、系统提示词中的使用指导与结果包络；脚本解析、执行、上限与取消位于引擎之后。执行为前台：父级轮次会阻塞到整个工作流结算，非正常结束是错误，绝不是部分输出。仅当用户明确要求工作流式或大型多 agent 编排时选择它；一两项委派时优先使用普通 subagent 调用。
 
-工具有三个参数：`meta`（必需的身份数据：`name`、`description` 和可选的进度注解）、`script`（必需的纯 JavaScript 脚本体，不含 `export const meta` 语句；工具描述包含完整的编写约定）以及 `args`（可选 JSON 对象，作为全局变量 `args` 向脚本公开；裸列表应包装到字段中，使协议 schema 如实表达形态）。插件还会贡献一个 `tool:<toolName>` 系统提示词段，其中包含使用策略：只有用户明确要求工作流／大型编排时才使用该工具；一两项委派优先使用普通 subagent 调用。这遵循工具指导随工具插件交付、绝不放入部署 persona 的约定。

-收集是同步的（类似 [`dsh-tool-subagent`](../../subagent/tool-subagent/README.zh.md)）：`execute` 启动运行并等待 `run.result`；这些操作位于 `try/finally` 中，该结构总会 dispose（资源释放）运行，使脚本及其子 agent（智能体）在每条路径上完全停稳。`exec.signal` 会桥接到 `run.cancel()`，包括启动前已经中止的情况。非 `completed` 结束原因会映射为报告原因的 `isError` 结果，绝不会把局部输出当作成功；`start()` 同步抛出的解析／meta 失败会变成模型可据以修正的 `isError`。完成时返回规范值 `{ runId, agentsStarted, result }`；Native 渲染器保留 meta 名称、agent 数量和 JSON 值，只会在 `maxResultChars` 处截断该投影。
+-----
 
-对于根 transport 执行（`exec.parent` 缺省），工具还会把运行投影到调用 Agent 的 Session：`start()` 返回后写 run-start，只记录 `run.id` 匹配的成员开始与结束，并且只在 `run.result` 已取得且 `dispose()` 完全停稳后写 run-end。嵌套 transport 调用照常执行，但不写工作流记录。任一次 Session append 首次失败后，本运行会停止后续记录并只告警一次，留下空记录或合法连续前缀，同时不改变工具结果和清理。
+<a id="use-this-package"></a>
+## 使用本包
 
-浏览器安全的 `@deepseek-ai/dsh-tool-workflow/types` 子路径拥有这四类 log-only 事件 payload 及其 `SessionEventMap` 声明。包 invariant 会在冷加载和实时追加时拒绝重复 start、未配对成员、仍有开放成员的终点和 run-end 后更新，同时允许缺失终态后缀的连续前缀。
+`workflow` 工具运行由模型编写的编排脚本，把工作扇出到多个 subagent，并返回脚本的最终 JSON 值。仅当用户明确要求工作流或大型多 agent 编排时使用——例如跨多个文件的审计、一次迁移、多角度研究；一两项委派时优先使用普通 subagent 调用。
 
-## 渲染意图
+### 调用工具
 
-渲染意图预先确定（见[渲染意图 Agent Note](../../../.agents/notes/implemented/architecture/2026-07-02-tool-render-intent-union.zh.md)）：使用一个 `generic` 卡片，标题为 `workflow: <meta.name>`，直接从 `args.meta.name` 读取（呈现是参数的纯函数，不要求引擎解析）；脚本文本作为 `rawInput` 携带。结果继续使用 generic 卡片。
+模型提交三个参数：`meta`（必需的身份数据：`name`、`description`，以及可选的 `whenToUse` 与 `phases`）、`script`（必需的纯 JavaScript 脚本体——不含 `export const meta` 语句；工具描述携带完整的编写约定）与 `args`（可选 JSON 对象，作为全局变量 `args` 向脚本公开；裸列表应包装到字段中，使协议 schema 如实表达形态）。
 
-## 配置
+成功返回规范包络 `{ runId, agentsStarted, result }`，向模型渲染为 `workflow "<name>" completed (<count> agent<optional-s>).`，后接 `Return value:` 与美化打印的 JSON。无法启动的工作流——脚本解析或 meta 校验失败——返回模型可以修正的错误。取消与执行失败返回 `Error: workflow run was cancelled` 或 `Error: workflow run failed: <error>`；部分输出绝不会被报告为成功。
 
-| 键 | 默认值 | 含义 |
+### 运行期间的预期
+
+脚本运行期间，父级轮次会等待：工具启动运行、等待其结果，并始终 dispose（资源释放）它，因此脚本及其子 agent 在每条路径上完全停稳——包括从父级步骤中止信号桥接而来的取消。模型只看到最终结果，永远不会看到中间子 agent 消息；子 agent 自己的工作不会进入父级对话。
+
+### 配置
+
+| 字段 | 默认值 | 含义 |
 |---|---|---|
 | `toolName` | `workflow` | 要注册的面向模型工具名称。 |
 | `maxResultChars` | `50000` | 渲染结果上限；更长的 JSON 会被截断并附上提示。 |

+### 运行生命周期
+
+`execute` 启动运行，并在 `try/finally` 内等待 `run.result`；该结构总会 dispose 运行。`exec.signal` 会桥接到 `run.cancel()`，包括启动前已经中止的情况。非 `completed` 结束原因会映射为报告原因的 `isError` 结果；完成时渲染 `{ runId, agentsStarted, result }`，Native 渲染器只会在 `maxResultChars` 处截断该投影。
+
+### 持久会话记录
+
+对于根 transport 执行（`exec.parent` 缺省），工具会用四个 log-only 事件把运行投影到调用 Agent 的 Session：`start()` 返回后写 run-start，只记录 `run.id` 匹配的成员开始与结束，并且只在结果可用且 dispose 完全停稳后写 run-end。嵌套 transport 调用照常执行，但不写任何记录。任一次 Session append 首次失败后，本运行会停止后续记录并只告警一次，留下空记录或合法连续前缀，同时不改变工具结果和清理。包 invariant 会在冷加载与实时追加时拒绝重复 start、未配对成员、仍有开放成员的终点与 run-end 后更新，同时允许缺失终态后缀的连续前缀。
+
+### 渲染意图
+
+按[渲染意图 Agent Note](../../../.agents/notes/implemented/architecture/2026-07-02-tool-render-intent-union.zh.md)预先确定：使用 `generic` 卡片，标题为 `workflow: <meta.name>`，直接从 `args.meta.name` 读取——呈现是参数的纯函数——脚本文本作为 `rawInput` 携带。结果继续使用 generic 卡片。

-This package implements `WorkflowEngine` with one Node worker thread per run. The worker executes the orchestration script; child agents remain on the host and are reached through `ctx.subagents` over a typed host/worker protocol.
+## Summary
 
-The package root exports the default engine plugin and its `Config`; the worker protocol, runtime, and session modules stay private to the implementation. The operational `./worker` entry remains the engine's spawn target.
+`dsh-workflow-worker-thread` implements the workflow engine with one Node worker thread per run: the orchestration script executes inside a fresh worker while its `agent()` calls reach host subagents over a typed host/worker protocol. A synchronous script loop cannot block the harness event loop, and a script that ignores cancellation can be terminated with its worker. The isolation is containment, not a security boundary — a model-written script has the same trust premise as the model's existing bash access, and escaping the `node:vm` context recovers the worker's process authority. Mount this engine to give `ctx.workflowEngine` a concrete implementation; a composition that loads it with `dsh-tool-workflow` gives the model the `workflow` tool.
 
-The split has one primary purpose: a synchronous script loop cannot block the harness event loop, and a script that ignores cancellation can be terminated with its worker. It is not a security sandbox.

-Workflow scripts are model-written and have the same trust premise as the model's existing bash access. `node:vm` inside a worker is an API-shaping mechanism, not a security boundary: an escaped script can recover Node capabilities with the host process's privileges.
+-----
 
-The worker still provides useful containment:
+<a id="use-this-package"></a>
+## Use this package
 
-- Script CPU work and synchronous spins stay off the host event loop.
-- `worker.terminate()` gives disposal a real final stop.
-- The worker starts with an empty environment, except unbuilt loader plumbing, so ambient credentials do not cross through `process.env`.
-- Host/worker messages use structured-clone data, with plain-JSON validation at the script boundary.
+Mount this engine when a composition needs the workflow capability: each orchestration script runs in its own worker thread, off the host event loop, and the `workflow` and `ralph` tools in the shipped composition execute on it. Do not use it as a sandbox for genuinely untrusted scripts — hostile code needs a separate-process or container engine.
 
-A genuinely untrusted-script sandbox would require a different engine behind the same workflow seam.
+### Minimal configuration
 
-## Script contract
+Loading the engine registers `ctx.workflowEngine`; adding `dsh-tool-workflow` on top gives the model the `workflow` tool. Every config field is optional:
 
-The workflow's `meta` is host-provided data, not evaluated script text. The engine validates its required `name` and `description`, rejects unknown fields, and parse-checks the body before returning a run.
+```yaml
+- name: '@deepseek-ai/dsh-workflow-worker-thread'
+- name: '@deepseek-ai/dsh-tool-workflow'
+```
 
-Inside the worker, the script receives `args` and these hooks:
-
-- `agent(prompt, { label, phase, schema, model })` starts one host-side subagent. With a schema it returns the structured value; otherwise it returns final text. An ordinary failed child yields `null`.
-- `parallel(thunks)` runs thunks under the configured concurrency limit.
-- `pipeline(items, ...stages)` passes `(previous, item, index)` without a cross-stage barrier.
-- `phase(title)` and `log(message)` emit observer narration.
-
-Unknown options, malformed arguments, unsupported schemas, tripped caps, provider-start failures, and infrastructure result failures are fatal workflow errors. No timers, filesystem API, or Node globals are intentionally injected, though the trust caveat above still applies.
-
-## Run sequence
-
-`start()` validates meta, parses the body, resolves a registered normalized provider route, and resolves any per-run total-child cap before creating a worker or publishing `workflow/start`. A requested `maxTotalAgents` must be a positive safe integer no greater than the engine's configured deployment ceiling. Source mode installs TypeScript transforms through a data-URL bootstrap; built mode passes sibling `lib/worker.cjs` as a filesystem path because pkg's VFS hook expects CommonJS. Both work under ordinary Node. A ready/go handshake prevents a start-signal cancellation racing worker boot from executing the script's initial synchronous slice.
-
-For each `agent()` call:
-
-1. The worker sends `child-start` with a plain-data prompt and options.
-2. The host calls the start request's provider override, or otherwise the configured provider, through async `SubagentRuntime.start`, passing the workflow's parent and one canonical per-run abort signal. Provider choice applies to every child in that run and is not visible to the script.
-3. If start rejects, the host sends `child-start-error`; provider startup has already reached quiescence and no child lifecycle event is emitted.
-4. If start fulfills while the workflow still admits work, the host records the run, observes `result`, then sends `child-started`. Even an already-settled result is forwarded afterward, preserving start-before-result order.
-5. The worker emits paired `workflow/agent-start` and `workflow/agent-end` narration and requests child disposal after collection.
-
-Provider starts are tracked separately from published children. If cancellation, worker death, or normal workflow settlement closes admission while a start is pending, the shared signal aborts it. A provider that nevertheless fulfills after closure is disposed by the host and never announced to the worker.
-
-## Value boundary
-
-Values leaving the script pass through `materializeFromRealm`, which accepts plain, lossless JSON data and rejects exotic prototypes, functions, symbols, cycles, sparse arrays, non-finite numbers, and nested `undefined`. The walk runs in the worker, and defines object keys as data properties so `__proto__` cannot mutate a prototype.
-
-Child results are projected and snapshotted before crossing from the host to the worker. This is a real process-like serialization boundary; it is deliberately different from trusted same-process workflow and subagent event payloads, which are borrowed immutable values.
-
-## Cancellation and disposal
-
-`WorkflowRun.cancel()` records the first reason, tells the worker to cancel, aborts the one signal shared by every pending and published child, and arms the `disposeGraceMs` timer. Worker hooks then throw `CANCELLED` at their next await. If the run remains unsettled at the deadline, the host resolves it as cancelled, pairs stranded child lifecycle events, and terminates the worker.
-
-The subagent seam has one cancellation channel: the request signal. There is no separate child-cancel RPC. Published child teardown uses `run.dispose()`; pending provider starts remain provider-owned until their promise rejects or fulfills.
-
-Normal settlement also aborts pending starts and begins disposing any published fire-and-forget children before the result becomes externally settled. The host's quiescence condition includes both pending starts and published child disposals, so cleanup does not forget an async startup transaction.
-
-`dispose()` is idempotent. It cancels the run, starts host-driven disposal immediately, waits for result plus child quiescence up to the same grace, terminates the worker unconditionally, and performs a final survivor sweep. Per-child disposal is memoized so worker RPC, host cancellation, death cleanup, and public disposal all join one operation.
-
-## Outcome and event guarantees
-
-Terminal outcome is first-wins at host claim points. An accepted external cancellation overrides a later non-cancelled worker result; a result or worker death that claims first cannot be rewritten by reentrant cleanup callbacks.
-
-Worker error, message failure, or premature exit closes message admission before cleanup, then resolves `error` unless cancellation already owns the run. Late queued messages cannot create children or narrate after that logical boundary.
-
-The host keeps a ledger of forwarded child starts. A graceful worker supplies their ends; death or force termination synthesizes any missing end as cancelled. Every forwarded `workflow/agent-start` is therefore paired exactly once, although cleanup after an already-arrived workflow result may complete afterward.

The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-workflow-worker-thread) is the exhaustive source for every accepted field.
 
+### What a run gives you
+
+When a run starts, the script body executes in the worker with top-level `await` and the hooks `agent()`, `parallel()`, `pipeline()`, `phase()`, and `log()`; `meta` and `args` arrive as plain JSON data, never evaluated code. Every `agent()` call starts a host-side subagent under the configured provider, with the run's parent as the parent of every child. The run settles with the script's final JSON value; an ordinary child failure resolves `agent()` to `null` so the script can handle it.
+
+A malformed meta block, a body that does not parse, an unavailable provider route, or a per-run cap above the ceiling is rejected synchronously before a worker exists, so the caller sees a violation list and can correct the call. During execution, hook misuse and tripped caps kill the script with a fatal workflow error. Cancellation is bounded: a script that ignores it is force-settled as cancelled and its worker terminated after `disposeGraceMs`.
+
+### Trust expectations
+
+Script CPU work and synchronous spins stay off the host event loop, `worker.terminate()` gives disposal a real final stop, and the worker starts with a scrubbed environment — only platform temp paths and, in source mode, `TSX_TSCONFIG_PATH` — so ambient credentials do not cross through `process.env`. Host/worker messages use structured-clone data with plain-JSON validation at the script boundary.
+
+None of this is a security boundary: no timers, filesystem API, or Node globals are intentionally injected, but escaped code can still reach Node with the worker's process authority.

+This section explains the engine's isolation design and run mechanics; observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+One worker thread per run keeps a misbehaving script from stalling the host and makes force termination possible: the script runs in an escapable `node:vm` context inside the worker, and `agent()` calls cross a typed host/worker protocol back to `ctx.subagents`. The vm context shapes the script's API surface; it is not a security sandbox.

+
+### Run sequence
+
+`start()` validates the meta block, parses the body, resolves the provider route, and resolves the per-run total-child cap before creating a worker or publishing `workflow/start`. A ready/go handshake prevents a start-signal cancellation racing worker boot from executing the script's initial synchronous slice; source mode installs TypeScript transforms through a data-URL bootstrap, while built mode passes the sibling `lib/worker.cjs` bundle.
+
+For each `agent()` call the worker sends a `child-start`; the host starts the provider (the request's override, or the configured provider) through the subagent seam, attributes the child to the run's parent, and reports start or start-error back. Provider choice applies to every child in the run and is not visible to the script. Provider starts are tracked separately from published children, so a pending start is aborted by the shared signal when cancellation, worker death, or normal settlement closes admission.

+Open directions: a pooled or warm runtime and a cross-run script cache to avoid one worker per run; a genuine process or container engine for untrusted scripts behind the same seam. The built `./worker` entry ships as a CommonJS bundle because pkg's VFS hook expects CommonJS; source mode installs tsx transforms through a data-URL bootstrap.

 # @deepseek-ai/dsh-workflow-worker-thread
 
 [English](README.md) | 中文
 
-本包为 `WorkflowEngine` 提供实现，每次运行使用一个 Node worker thread。worker 执行编排脚本；子 agent（智能体）留在宿主上，脚本通过带类型的宿主／worker 协议经由 `ctx.subagents` 访问它们。
+## 概述
 
-包根目录默认导出引擎插件及其 `Config`；worker 协议、运行时和会话模块均为实现私有。操作入口 `./worker` 仍是引擎的 spawn 目标。
+`dsh-workflow-worker-thread` 以每次运行一个 Node worker thread 的方式实现工作流引擎：编排脚本在一个全新 worker 内执行，其 `agent()` 调用通过带类型的宿主／worker 协议触达宿主 subagent。同步脚本循环不会阻塞 harness 事件循环，忽略取消的脚本可以连同其 worker 一起终止。这种隔离只是 containment（隔离），不是安全边界——由模型编写的脚本与模型已有的 bash 访问具有相同的信任前提，逃逸 `node:vm` 上下文即可重新取得 worker 的进程权限。挂载本引擎即为 `ctx.workflowEngine` 提供具体实现；与 `dsh-tool-workflow` 一起加载的组合会把 `workflow` 工具交给模型。
 
-这种拆分只有一个主要目的：同步脚本循环不能阻塞 harness 事件循环，忽略取消的脚本可以连同其 worker 一起终止。它不是安全沙箱。

+-----
 
-worker 仍提供实用的隔离：
+<a id="use-this-package"></a>
+## 使用本包
 
-- 脚本 CPU 工作和同步自旋不会占用宿主事件循环；
-- `worker.terminate()` 为 dispose（资源释放）提供真实的最终停止手段；
-- 除未构建 loader 所需的衔接配置外，worker 以空环境启动，因此环境凭据不会通过 `process.env` 跨越边界；
-- 宿主/worker 消息使用结构化克隆数据，并在脚本边界执行普通 JSON 校验。
+当组合需要工作流能力时挂载本引擎：每个编排脚本都在独立 worker thread 中、宿主事件循环之外运行，已发布组合中的 `workflow` 与 `ralph` 工具都在其上执行。不要把它当作真正不可信脚本的沙箱——恶意代码需要独立进程或容器引擎。
 
-真正的不可信脚本沙箱需要在同一工作流 seam 背后采用不同引擎。
+### 最小配置
 
-## 脚本约定
+加载本引擎即注册 `ctx.workflowEngine`；在其上添加 `dsh-tool-workflow` 会把 `workflow` 工具交给模型。每个配置字段都是可选的：
 
-工作流的 `meta` 是宿主提供的数据，而不是待求值的脚本文本。引擎会校验必需的 `name` 和 `description`、拒绝未知字段，并在返回运行前检查脚本正文能否解析。
+```yaml
+- name: '@deepseek-ai/dsh-workflow-worker-thread'
+- name: '@deepseek-ai/dsh-tool-workflow'
+```
 
-在 worker 内，脚本会收到 `args` 以及以下钩子：
-
-- `agent(prompt, { label, phase, schema, model })` 启动一个宿主侧 subagent。提供 schema 时返回结构化值，否则返回最终文本。普通子 agent 失败会产生 `null`；
-- `parallel(thunks)` 在已配置的并发限制下运行 thunk；
-- `pipeline(items, ...stages)` 在没有跨阶段屏障的情况下传递 `(previous, item, index)`；
-- `phase(title)` 和 `log(message)` 发出观察器叙述。
-
-未知选项、格式错误的参数、不支持的 schema、超出上限、提供方启动失败和基础设施结果失败都属于致命工作流错误。有意不注入 timer、文件系统 API 或 Node 全局变量，但上述信任注意事项仍然适用。
-
-## 运行顺序
-
-`start()` 会校验 meta、解析脚本正文、解析一个已注册且规范化的提供方路由，并解析每次运行的子 agent 总数上限，然后才创建 worker 或发布 `workflow/start`。请求的 `maxTotalAgents` 必须是正安全整数，且不能超过引擎配置的部署上限。源代码模式通过 data URL bootstrap 安装 TypeScript 转换；构建模式把同级 `lib/worker.cjs` 作为文件系统路径传入，因为 pkg 的虚拟文件系统（VFS）钩子要求 CommonJS。两者都能在普通 Node 下运行。ready/go 握手可以避免启动信号取消与 worker 启动发生竞态，导致脚本最初的同步片段被执行。
-
-对于每次 `agent()` 调用：
-
-1. worker 发送 `child-start`，其中包含普通数据提示词和选项。
-2. 宿主通过异步 `SubagentRuntime.start` 调用启动请求中指定的提供方，否则调用已配置的提供方；调用会传入工作流父级和该次运行共用的唯一中止信号。提供方选择应用于该次运行的每个子 agent，对脚本不可见。
-3. 如果启动被拒绝，宿主会发送 `child-start-error`；提供方启动已经完全停稳，不会发出子 agent 生命周期事件。
-4. 如果启动兑现时工作流仍接纳工作，宿主会记录该运行、观察 `result`，然后发送 `child-started`。即使结果已经结算，也只会随后转发，以保持先启动、后结果的顺序。
-5. worker 发出成对的 `workflow/agent-start` 和 `workflow/agent-end` 叙述，并在收集后请求 dispose 子 agent。
-
-提供方启动与已发布子 agent 分开跟踪。如果启动仍在等待，而取消、worker 死亡或正常工作流结算关闭了接纳，共享信号会中止该启动。即便提供方随后兑现，宿主也会 dispose 它，且绝不向 worker 通知。
-
-## 值边界
-
-离开脚本的值会经过 `materializeFromRealm`；该函数接受普通的无损 JSON 数据，并拒绝特殊原型、函数、symbol、循环、稀疏数组、非有限数和嵌套 `undefined`。遍历在 worker 内执行，并把对象键定义为数据属性，使 `__proto__` 无法改变原型。
-
-子 agent 结果从宿主跨越到 worker 之前，会先投影并制作快照。这是真正近似进程的序列化边界；它有意不同于可信的同进程工作流和 subagent 事件 payload，后者以不可变方式借用值。
-
-## 取消与 dispose
-
-`WorkflowRun.cancel()` 会记录第一个原因、通知 worker 取消、中止每个待处理及已发布子 agent 共享的唯一信号，并启动 `disposeGraceMs` 定时器。worker 钩子会在下次 await 时抛出 `CANCELLED`。如果运行到期限仍未结算，宿主会将其以已取消状态兑现、为悬空的子 agent 生命周期事件配对，并终止 worker。
-
-subagent seam 只有一个取消通道：请求信号。不存在单独的子 agent 取消 RPC。已发布子 agent 使用 `run.dispose()` 清理；待处理的提供方启动在其 promise 拒绝或兑现前仍由提供方负责。
-
-正常结算也会中止待处理启动，并在结果对外结算前开始 dispose 所有已发布但无需等待的子 agent。宿主的完全停稳条件同时包括待处理启动和已发布子 agent 的 dispose，因此清理不会遗漏异步启动事务。
-
-`dispose()` 是幂等的。它会取消运行、立即启动宿主驱动的 dispose、在同一宽限时间内等待结果和子 agent 完全停稳、无条件终止 worker，并执行最后一次幸存项扫描。每个子 agent 的 dispose 都会记忆化，使 worker RPC、宿主取消、死亡清理和公开 dispose 都汇入同一操作。
-
-## 结果与事件保证
-
-在宿主的结果确认点，终态结果遵循先到者胜。已接受的外部取消会覆盖后到的非取消 worker 结果；先完成确认的结果或 worker 死亡不能被可重入清理回调改写。
-
-worker 错误、消息失败或提前退出会在清理前关闭消息接纳，然后以 `error` 兑现；如果取消已经接管该运行，则不覆盖取消。后到的排队消息无法在该逻辑边界后创建子 agent 或发出叙述。
-
-宿主会维护已转发子 agent 启动的台账。优雅退出的 worker 会提供对应的结束事件；死亡或强制终止会把缺失的结束事件合成为已取消。因此，每个已转发的 `workflow/agent-start` 都会且只会配对一次，不过已经到达的工作流结果之后的清理可能稍后才完成。

-负责该引擎的消费方可以为一次运行设置 `WorkflowStartRequest.subagentProvider` 和 `WorkflowStartRequest.maxTotalAgents`。它们属于引擎级策略，不是脚本钩子或面向模型的选项；普通 `workflow` 工具不会设置两者。每次运行的子 agent 总数上限可以降低、但绝不能提高已配置的 `maxTotalAgents` 上限。
+负责该引擎的消费方可以为一次运行设置 `WorkflowStartRequest.subagentProvider` 与 `WorkflowStartRequest.maxTotalAgents`——这是引擎级策略，不是脚本钩子；普通 `workflow` 工具两者都不设置，单次运行的子 agent 总数上限可以降低、但绝不能提高已配置的上限。生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-workflow-worker-thread)是每个受支持字段的穷尽式真源。
 
+### 运行会得到什么
+
+运行启动后，脚本正文在 worker 中以顶层 `await` 执行，并可使用钩子 `agent()`、`parallel()`、`pipeline()`、`phase()` 与 `log()`；`meta` 与 `args` 以普通 JSON 数据到达，绝不作为代码求值。每次 `agent()` 调用都会在配置的提供方下启动一个宿主侧 subagent，并以运行的父级作为每个子 agent 的父级。运行以脚本的最终 JSON 值结算；普通子 agent 失败会把 `agent()` 兑现为 `null`，由脚本处理。
+
+格式错误的 meta 块、无法解析的正文、不可用的提供方路由或高于上限的单次运行上限，都会在 worker 存在之前被同步拒绝，调用方因此看到违规清单并可以修正调用。执行期间，钩子误用与超出上限会用致命工作流错误终止脚本。取消是有界的：忽略取消的脚本会在 `disposeGraceMs` 后被强制以 cancelled 结算，其 worker 被终止。
+
+### 信任预期
+
+脚本的 CPU 工作与同步自旋不会占用宿主事件循环，`worker.terminate()` 为 dispose（资源释放）提供真实的最终停止手段，worker 以清理后的环境启动——只注入平台临时路径以及（源码模式下）`TSX_TSCONFIG_PATH`——因此环境凭据不会通过 `process.env` 跨越边界。宿主／worker 消息使用结构化克隆数据，并在脚本边界执行普通 JSON 校验。
+
+以上都不是安全边界：有意不注入 timer、文件系统 API 或 Node 全局变量，但逃逸代码仍可以 worker 的进程权限触达 Node。

+
+本节解释引擎的隔离设计与运行机制；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+每次运行一个 worker thread，让行为异常的脚本无法拖垮宿主，并使强制终止成为可能：脚本在 worker 内可逃逸的 `node:vm` 上下文中运行，`agent()` 调用通过带类型的宿主／worker 协议回到 `ctx.subagents`。vm 上下文塑造脚本的 API 表面；它不是安全沙箱。
+
+### 源码地图

+| [`src/host.ts`](src/host.ts) | 一次运行的宿主侧：worker 启动、子 agent 编排、结算、dispose |
+| [`src/worker.ts`](src/worker.ts) | worker 入口：脚本执行、钩子实现、值物化 |

+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；worker 测试覆盖该边界） |
+
+### 运行顺序
+
+`start()` 在创建 worker 或发布 `workflow/start` 之前校验 meta 块、解析正文、解析提供方路由并解析单次运行的子 agent 总数上限。ready/go 握手可以避免启动信号取消与 worker 启动发生竞态、导致脚本最初的同步片段被执行；源代码模式通过 data URL bootstrap 安装 TypeScript 转换，构建模式则传入同级 `lib/worker.cjs` 包。
+
+每次 `agent()` 调用，worker 都会发送 `child-start`；宿主通过 subagent seam 启动提供方（请求的覆盖值，或配置的提供方），把子 agent 归属于运行的父级，并回报启动成功或启动错误。提供方选择应用于该运行的每个子 agent，对脚本不可见。提供方启动与已发布子 agent 分开跟踪，因此当取消、worker 死亡或正常结算关闭接纳时，待处理启动会被共享信号中止。
+
+### 值边界
+
+离开脚本的值会经过 realm 物化；该过程接受普通无损 JSON 数据，拒绝特殊原型、函数、symbol、循环、稀疏数组、非有限数与嵌套 `undefined`。子 agent 结果在从宿主跨入 worker 之前先投影并快照——这是真正近似进程的序列化边界，刻意区别于同进程工作流事件以不可变方式借用的值。
+
+### 取消与 dispose
+
+`cancel()` 记录第一个原因、通知 worker 取消、中止所有待处理与已发布子 agent 共享的唯一信号，并启动 `disposeGraceMs` 定时器；worker 钩子随后在下次 await 时抛出 `CANCELLED`。如果运行到期限仍未结算，宿主会将其以 cancelled 兑现、为悬空的子 agent 生命周期事件配对，并终止 worker。
+
+`dispose()` 是幂等的：它取消运行、立即启动宿主驱动的 dispose、在同一宽限期内等待结果与子 agent 完全停稳、无条件终止 worker，并执行最后一次幸存项扫描。每个子 agent 的 dispose 都会记忆化，使 worker RPC、宿主取消、死亡清理与公开 dispose 都汇入同一操作。

 # @deepseek-ai/dsh-workflow
 
 English | [中文](README.zh.md)
 
-The workflow seam (`ctx.workflowEngine`) executes a model-written orchestration script that can fan out subagents. The seam defines the script, run, result, error, and event contracts; an engine decides how to isolate and execute the script.
+## Summary
 
-`@deepseek-ai/dsh-workflow-worker-thread` is the current engine and `@deepseek-ai/dsh-tool-workflow` is the model-facing consumer. A future process or sandbox engine can replace the implementation without changing the tool.
+`dsh-workflow` runs a plain-JavaScript orchestration script and gives the caller a live run whose result resolves with the script's final JSON value. The script can fan out subagents with `agent()`, combine independent work with `parallel()` and `pipeline()`, and narrate progress with `phase()` and `log()`; agents normally drive this through the `workflow` tool from `dsh-tool-workflow`. A run is holder-owned: its result never rejects, cancellation and disposal are bounded, and every child is attributed to the invoking agent. The package ships no execution engine — `dsh-workflow-worker-thread` is the current one — so a different isolation strategy can replace it without changing what callers or the model see.
 
-The package root is the Host face. The browser-safe `@deepseek-ai/dsh-workflow/types` subpath contains run identities, metadata, results, and observe-only lifecycle payloads without importing `Agent`, Cordis services, or Host context declarations; Host-only `WorkflowStartRequest` and `WorkflowRun` live behind the package root.

-`WorkflowEngine.start(request): WorkflowRun` validates enough synchronously to reject a malformed meta block, unparseable script, unavailable provider route, or unsupported per-run limit before a run exists. Once returned, `WorkflowRun.result` never rejects: execution failures resolve with `stopReason: 'error'`, and cancellation resolves with `cancelled` within the engine's bounded grace.
+-----
 
-A run is holder-owned. Engine-plugin unload prevents new starts but does not revoke accepted runs. The holder must call `dispose()` on every path; disposal cancels remaining work and reaches or abandons quiescence within the documented bound.
+<a id="use-this-package"></a>
+## Use this package
 
-`WorkflowStartRequest` contains `{ meta, script, args?, subagentProvider?, maxTotalAgents?, parent, signal? }`. `parent` attributes every child agent to the invoking agent. `subagentProvider` optionally routes every child in that run without exposing provider choice to the script; omission uses the engine's configured provider. `maxTotalAgents` optionally lowers the engine's deployment ceiling for one run and is likewise invisible to the script. An implementation rejects invalid routes and limits synchronously. `meta` and `args` are plain data, not script fragments.
+Run a workflow when a task decomposes into many independent pieces that one script should coordinate — an audit across many files, a migration, multi-angle research — and the model explicitly asks for workflow-style orchestration. For one or two delegations, prefer a plain subagent call.
 
-`WorkflowRun` exposes `{ id, meta, result, cancel(reason?), dispose() }`. `WorkflowResult` contains `{ value, stopReason, error?, agentsStarted }`; `value` is plain JSON data or `null`.
+### The model-facing path
 
-## Events
+The model reaches the capability through the `workflow` tool from `dsh-tool-workflow`, which owns the call schema and result envelope; the engine supplies the execution underneath. A tool call submits `meta`, `script`, and optional `args` and returns `{ runId, agentsStarted, result }` when the run completes. The tool blocks the parent turn until the whole workflow settles, so the model sees one final outcome, never intermediate child messages.
 
-Workflow events are observe-only. They carry `WorkflowRunInfo` (`id` plus `meta`) rather than the live run, so listeners cannot acquire cancellation or disposal authority.
+### Running a workflow script
 
-- `workflow/start` / `workflow/end` pair the run.
-- `workflow/phase` and `workflow/log` expose script narration.
-- `workflow/agent-start` / `workflow/agent-end` pair each child call by `seq`; a child whose async provider start rejects emits neither.
+An orchestration script is a plain JavaScript body (not TypeScript) that runs with top-level `await` and ends with `return <json-value>`. The `meta` identity block and any `args` arrive as plain JSON data — never evaluated code. During execution the script calls the provided hooks: `agent(prompt, opts)` starts one subagent and resolves with its final text or, with a schema, a validated structured value; `parallel()` and `pipeline()` combine independent work; `phase()` and `log()` narrate progress for observers.
 
-Same-process event payloads are borrowed immutable values. Every listener is independently contained: a synchronous throw or rejected returned promise is logged without starving peers or changing execution.

+  () => agent('Review src/a.ts for correctness'),
+  () => agent('Review src/b.ts for correctness'),
+])
+return { reviewed: reviews.length }
+```
 
-## Failure discipline
+When the script settles, the run's result resolves with the returned value, the stop reason, and the number of children started. A script that returns nothing yields `null`.
 
-`WorkflowError` carries a code and a `fatal` flag. Fatal errors always escape `parallel()` and `pipeline()` instead of becoming an ordinary per-item `null`:
+### Programmatic runs
 
-- `SCRIPT_PARSE` / `META_INVALID` — the workflow cannot start.
-- `INVALID_ARGUMENT` / `UNSUPPORTED_OPTION` / `UNSUPPORTED_SCHEMA` — a hook call violates the engine contract.
-- `AGENT_CAP` / `ITEM_CAP` — configured safety limits were exceeded.
-- `AGENT_START` — the provider's async start rejected.
-- `AGENT_RESULT` — a published child's result rejected with an infrastructure fault.
-- `RESULT_UNSERIALIZABLE` — a script/worker value is not plain JSON data.
-- `CANCELLED` — cancellation owns the run and pending/future hooks reject.
+Plugin consumers can start a run directly: `ctx.workflowEngine.start({ script, meta, args?, parent, signal? })`. `parent` attributes every child to the invoking agent; `signal` cancels the run when aborted. `start()` validates the meta block and parses the script before a run exists, so a malformed request fails immediately with a violation list.
 
-A child that resolves normally with a non-completed stop reason is not an infrastructure exception: `agent()` returns `null`, allowing the script to handle an ordinary child failure.
+A returned run exposes `id`, `meta`, `result`, `cancel(reason?)`, and `dispose()`. The result never rejects: a script failure resolves with `stopReason: 'error'`, cancellation with `'cancelled'`. The caller owns the run — call `dispose()` on every path; it cancels remaining work and waits for script and children to settle within a bounded grace.
 
+### Failures and recovery
+
+A script that does not parse, a malformed meta block, an unavailable provider route, or an unsupported per-run limit is rejected synchronously before a run exists; the `workflow` tool reports these as errors the model can correct from. During execution, hook misuse — bad arguments, unknown options, unsupported schemas, tripped caps — kills the script loudly rather than dissolving into a per-item `null`. An ordinary child failure is not an infrastructure error: `agent()` resolves `null` and the script decides how to handle it.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains how the capability is split and where the contracts live; observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design concept
+
+The package separates the script, run, result, and event contracts from execution: any engine can implement `ctx.workflowEngine` behind the same vocabulary, and one engine serves a context at a time — loading a second engine fails loud, so swapping engines means changing which engine plugin the composition loads. The `workflow/*` events are observe-only: payloads carry run identity snapshots, never the live run, so listeners cannot acquire cancellation or disposal authority.
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Service definition, `workflow/*` event declarations, `WorkflowError` and its fatal flag |
+| [`src/types.ts`](src/types.ts) | Browser-safe vocabulary: `WorkflowMeta`, `WorkflowResult`, run and agent event info |
+| [`src/runtime-types.ts`](src/runtime-types.ts) | Host-only `WorkflowStartRequest` and `WorkflowRun` handles |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion: event pairing and identity checks |
+
+### Lifecycle and ownership
+
+A run is holder-owned: engine-plugin unload prevents new starts but does not revoke accepted runs, and the caller must dispose every run it starts. `dispose()` cancels if needed and awaits script and child quiescence within the engine's documented bound, so a consumer awaiting `result` is never wedged past a cancellation.
+
+`workflow/start` and `workflow/end` pair the run; `workflow/phase` and `workflow/log` carry script narration; `workflow/agent-start` and `workflow/agent-end` pair each child call by `seq`. Every listener is independently contained: a throwing listener is logged without starving peers or changing execution, and each receives its own payload clone.
+
+### Failure discipline
+
+`WorkflowError` carries a machine-routable code and a `fatal` flag; every code is fatal, and `parallel()` and `pipeline()` re-throw fatal errors instead of mapping the item to `null` — a typo'd option must kill the script loudly. Codes cover start failures, contract violations, exceeded caps, provider and result faults, unserializable values, and cancellation; the exact set and meanings live in [`src/index.ts`](src/index.ts).
+
+The per-item `null` is reserved for child-run failures and ordinary in-stage script errors, so a child that resolves normally with a non-completed stop reason is not an infrastructure exception: `agent()` returns `null`, letting the script handle an ordinary child failure.

 ## Known Limitations and Deferred Work
 
+<a id="known-limitations-and-deferred-work"></a>
+
+
+These limits define what the capability does not yet support. They are current constraints, not a task backlog.
+
 - **Foreground collection only** — the caller owns one live run and awaits it; background start/poll, spill handles, and detached collection are deferred.
 - **No journaling or resume** — scripts, child progress, and intermediate values are not checkpointed, so a process restart cannot continue a run.
-- **No saved or nested workflows** — the seam starts caller-supplied scripts only, and a workflow script receives no `workflow()` hook for recursive orchestration.
-- **No token-budget vocabulary** — engines cap concurrency, items, and children, but neither the request nor result accounts for model tokens across children.
+- **No saved or nested workflows** — the capability starts caller-supplied scripts only, and a workflow script receives no `workflow()` hook for recursive orchestration.
+- **No token-budget vocabulary** — engines cap concurrency, items, and children, but neither the request nor the result accounts for model tokens across children.
 - **Runs are holder-owned, not service-tracked** — unloading the engine does not discover independent live handles; every consumer must dispose the run it started.

 # @deepseek-ai/dsh-workflow
 
 [English](README.md) | 中文
 
-工作流 seam（扩展点，`ctx.workflowEngine`）执行由模型编写、可扇出 subagent 的编排脚本。该 seam 定义脚本、运行、结果、错误和事件契约；引擎负责决定如何隔离并执行脚本。
+## 概述
 
-`@deepseek-ai/dsh-workflow-worker-thread` 是当前引擎，`@deepseek-ai/dsh-tool-workflow` 是面向模型的消费方。未来的进程或沙箱引擎可以替换实现，而无需更改工具。
+`dsh-workflow` 运行一段纯 JavaScript 编排脚本，并交给调用方一个活动运行，其 result 在脚本结算时以脚本的最终 JSON 值兑现。脚本可以用 `agent()` 扇出 subagent，用 `parallel()` 和 `pipeline()` 组合独立工作，用 `phase()` 和 `log()` 叙述进度；agent 通常通过 `dsh-tool-workflow` 的 `workflow` 工具驱动这一切。运行由持有方负责：其 result 绝不拒绝，取消与 dispose（资源释放）有界，每个子 agent 都归属于调用它的 agent。本包不附带执行引擎——当前引擎是 `dsh-workflow-worker-thread`——因此可以用不同的隔离策略替换它，而不改变调用方或模型看到的内容。
 
-包根是 Host face。浏览器安全的 `@deepseek-ai/dsh-workflow/types` 子路径包含运行身份、元数据、结果和仅供观察的生命周期 payload，不导入 `Agent`、Cordis service 或 Host Context 声明；Host 专用的 `WorkflowStartRequest` 与 `WorkflowRun` 只从包根提供。

-`WorkflowEngine.start(request): WorkflowRun` 会同步完成足够多的校验，在运行创建前拒绝格式错误的 meta 块、无法解析的脚本、不可用的提供方路由或不受支持的单次运行限制。返回后，`WorkflowRun.result` 绝不拒绝：执行失败以 `stopReason: 'error'` 兑现，取消则在引擎有限的宽限时间内以 `cancelled` 兑现。
+-----
 
-运行由持有方负责。引擎插件卸载会阻止新的启动，但不会撤销已接受的运行。持有方必须在每条路径上调用 `dispose()`；dispose（资源释放）会取消剩余工作，并在文档规定的期限内达到或放弃完全停稳。
+<a id="use-this-package"></a>
+## 使用本包
 
-`WorkflowStartRequest` 包含 `{ meta, script, args?, subagentProvider?, maxTotalAgents?, parent, signal? }`。`parent` 把每个子 agent（智能体）归属于调用 agent。`subagentProvider` 可以为该次运行的所有子 agent 指定路由，同时不向脚本公开提供方选择；省略时使用引擎配置的提供方。`maxTotalAgents` 可以为一次运行降低引擎的部署上限，同样对脚本不可见。实现会同步拒绝无效路由和限制。`meta` 与 `args` 是普通数据，不是脚本片段。
+当任务分解为许多独立部分、适合用一段脚本统一协调——例如跨多个文件的审计、一次迁移、多角度研究——且模型明确要求工作流式编排时，运行工作流。一两项委派时，优先使用普通 subagent 调用。
 
-`WorkflowRun` 公开 `{ id, meta, result, cancel(reason?), dispose() }`。`WorkflowResult` 包含 `{ value, stopReason, error?, agentsStarted }`；`value` 是普通 JSON 数据或 `null`。
+### 模型侧路径
 
-## 事件
+模型通过 `dsh-tool-workflow` 的 `workflow` 工具触达该能力；该工具拥有调用 schema 与结果包络，引擎提供其下的执行。一次工具调用提交 `meta`、`script` 与可选 `args`，运行完成时返回 `{ runId, agentsStarted, result }`。工具会阻塞父级轮次直到整个工作流结算，因此模型只看到最终结果，永远不会看到中间子 agent 消息。
 
-工作流事件只供观察。它们携带 `WorkflowRunInfo`（`id` 加 `meta`），而不是活动运行，因此监听器无法取得取消或 dispose 权限。
+### 运行工作流脚本
 
-- `workflow/start` / `workflow/end` 为运行配对；
-- `workflow/phase` 和 `workflow/log` 公开脚本叙述；
-- `workflow/agent-start` / `workflow/agent-end` 按 `seq` 为每次子 agent 调用配对；提供方的异步启动调用被拒绝时，该子 agent 不会发出其中任何一个事件。
+编排脚本是纯 JavaScript 脚本体（不是 TypeScript），以顶层 `await` 运行并以 `return <json-value>` 结尾。`meta` 身份块与任何 `args` 都以普通 JSON 数据到达——绝不作为代码求值。执行期间脚本调用提供的钩子：`agent(prompt, opts)` 启动一个 subagent，并以其最终文本、或在提供 schema 时以经过校验的结构化值兑现；`parallel()` 与 `pipeline()` 组合独立工作；`phase()` 与 `log()` 为观察者叙述进度。
 
-同进程事件 payload 是以不可变方式借用的值。每个监听器都独立隔离：同步抛出异常或返回的 promise 被拒绝时，只会记录日志，不会阻塞同级监听器或改变执行。
+```text
+// Script body — runs with top-level await, ends with a JSON return value:
+const reviews = await parallel([
+  () => agent('Review src/a.ts for correctness'),
+  () => agent('Review src/b.ts for correctness'),
+])
+return { reviewed: reviews.length }
+```
 
-## 失败纪律
+脚本结算时，运行的 result 以返回值、结束原因和已启动的子 agent 数量兑现。脚本不返回值时得到 `null`。
 
-`WorkflowError` 携带一个代码和 `fatal` 标志。致命错误总会逸出 `parallel()` 和 `pipeline()`，而不会变成普通的逐项 `null`：
+### 编程方式运行
 
-- `SCRIPT_PARSE` / `META_INVALID`：工作流无法启动；
-- `INVALID_ARGUMENT` / `UNSUPPORTED_OPTION` / `UNSUPPORTED_SCHEMA`：钩子调用违反引擎契约；
-- `AGENT_CAP` / `ITEM_CAP`：超过已配置的安全上限；
-- `AGENT_START`：提供方的异步启动调用被拒绝；
-- `AGENT_RESULT`：已发布子 agent 的结果因基础设施故障而被拒绝；
-- `RESULT_UNSERIALIZABLE`：脚本/worker 值不是普通 JSON 数据；
-- `CANCELLED`：取消会接管该运行，待处理和未来的钩子都会拒绝。
+插件消费方可以直接启动运行：`ctx.workflowEngine.start({ script, meta, args?, parent, signal? })`。`parent` 把每个子 agent 归属于调用它的 agent；`signal` 在中止时取消运行。`start()` 在运行存在之前校验 meta 块并解析脚本，因此格式错误的请求会立即以违规清单失败。
 
-子 agent 若以非完成的结束原因正常兑现，并不属于基础设施异常：`agent()` 返回 `null`，使脚本可以处理普通的子 agent 失败。
+返回的运行公开 `id`、`meta`、`result`、`cancel(reason?)` 与 `dispose()`。result 绝不拒绝：脚本失败以 `stopReason: 'error'` 兑现，取消以 `'cancelled'` 兑现。调用方拥有该运行——每条路径都要调用 `dispose()`；它会取消剩余工作，并在有界宽限期内等待脚本与子 agent 完全停稳。
 
+### 失败与恢复
+
+无法解析的脚本、格式错误的 meta 块、不可用的提供方路由或不受支持的单次运行限制，都会在运行存在之前被同步拒绝；`workflow` 工具把这些报告为模型可以修正的错误。执行期间，钩子误用——错误参数、未知选项、不支持的 schema、超出上限——会响亮地终止脚本，而不会溶解为逐项 `null`。普通子 agent 失败不是基础设施错误：`agent()` 以 `null` 兑现，由脚本决定如何处理。

+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释能力如何拆分、契约位于何处；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+本包把脚本、运行、结果与事件契约同执行分开：任何引擎都可以在同一词汇背后实现 `ctx.workflowEngine`，一个上下文同时只有一个引擎——加载第二个引擎会立即失败，因此更换引擎意味着更改组合所加载的引擎插件。`workflow/*` 事件只供观察：payload 携带运行身份快照，绝不携带活动运行，因此监听器无法取得取消或 dispose 权限。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 服务定义、`workflow/*` 事件声明、`WorkflowError` 及其 fatal 标志 |
+| [`src/types.ts`](src/types.ts) | 浏览器安全词汇：`WorkflowMeta`、`WorkflowResult`、运行与 agent 事件信息 |
+| [`src/runtime-types.ts`](src/runtime-types.ts) | 仅宿主的 `WorkflowStartRequest` 与 `WorkflowRun` 句柄 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件：事件配对与身份校验 |
+
+### 生命周期与归属
+
+运行由持有方负责：引擎插件卸载会阻止新的启动，但不会撤销已接受的运行，调用方必须 dispose 自己启动的每个运行。`dispose()` 在需要时取消，并在引擎文档规定的期限内等待脚本与子 agent 完全停稳，因此等待 `result` 的消费方绝不会因取消而卡死。
+
+`workflow/start` 与 `workflow/end` 为运行配对；`workflow/phase` 与 `workflow/log` 携带脚本叙述；`workflow/agent-start` 与 `workflow/agent-end` 按 `seq` 为每次子 agent 调用配对。每个监听器都独立隔离：抛错的监听器只记录日志，不会饿死同级监听器或改变执行，并且每个监听器都会收到自己的 payload 副本。
+
+### 失败纪律
+
+`WorkflowError` 携带机器可路由的 code 与 `fatal` 标志；每个 code 都是致命的，`parallel()` 与 `pipeline()` 会重新抛出致命错误，而不是把条目映射为 `null`——拼错的选项必须响亮地终止脚本。code 覆盖启动失败、契约违规、超出上限、提供方与结果故障、不可序列化值与取消；完整集合与含义见 [`src/index.ts`](src/index.ts)。
+
+逐项 `null` 只保留给子运行失败与阶段内普通脚本错误，因此以非完成结束原因正常结算的子 agent 不属于基础设施异常：`agent()` 返回 `null`，让脚本处理普通子 agent 失败。

-This family owns persistent workspaces: user directories with titles and ordered session membership.
+## Summary
+
+The workspace group provides the durable project list behind a host UI: one product package, `workspace`, that names user directories as projects, keeps them in a stable order, and groups each project's sessions under it. With it, a UI can show a sidebar of projects with their sessions, hide a session from the grouping without deleting it, and remove a project — removal never deletes the folder or the session histories, which become ungrouped. The group is host-side only: no tools, prompts, or session events, so the model and the agent loop never see it. Use it when the product shows a persistent workspace or project surface; it needs a session store and a persistence backend alongside it.

-Workspace entity registry (`ctx.workspaceRegistry`) for the DeepSeek Harness: durable workspace records, stable workspace order, and a newest-first candidate session index stored through the domain data form. Consumers see the `Workspace` interface; the entity implementation stays package-private.
+## Summary
 
-The entity/storage rationale lives in the [domain Agent Note](../../../.agents/notes/proposed/architecture/2026-07-24-domain-kv-storage-and-workspace.md); header-only bootstrap and GUI ordering live in the [Workspace UI product-flow Agent Note](../../../.agents/notes/implemented/feature/2026-07-25-workspace-ui-product-flow.md).
+`dsh-workspace` gives a host a persistent set of workspaces: named user directories, each with the sessions that ran in it, kept in a stable order across restarts. With it, a UI can show a sidebar of projects, attach sessions to the right project, hide a session from the grouping without losing it, and remove a project — removal never deletes the folder or the session histories, which become ungrouped. Use it in GUI or host compositions that need durable project grouping; headless and minimal runs can omit it entirely. The package is host-side only: the model, tools, and agent loop never see it, so it adds no tokens, prompts, or request context. It needs a session store and a persistence backend mounted alongside it; setup is a few composition rows.
 
-## Shape
+## Table of Contents
 
-- `ctx.workspaceRegistry.create(path, title?)` — canonicalizes `path` via `fs.realpath`, rejects a nonexistent or non-directory path, creates at most one record per canonical path, and prepends a new record to durable workspace order. Repeated calls for that path return the existing workspace without changing its title; different paths may share a display title.
-- `ctx.workspaceRegistry.get(id)` / `list()` / `resolveByPath(path)` — cache-served lookups. `list()` is synchronous and follows durable registry order; `resolveByPath` is async because it applies the same `realpath` canon and rejects a missing path rather than creating it.
-- `ctx.workspaceRegistry.insertBefore(id, before?)` — moves a registered Workspace within durable registry order, DOM-insertBefore-like: before the anchor, or appended when the anchor is omitted. A source or anchor absent from the registry rejects without writing; a self-anchor or move to the current position resolves without writing. The returned id list is the complete committed order.
-- `ctx.workspaceRegistry.delete(id)` — removes only the Workspace registration, its durable order entry, and its session account. Unknown ids return `false`; a removed record returns `true`. The directory, user files, live Sessions, and persisted session logs are never touched, so those Sessions become Ungrouped. A table-write failure restores the prior order and published entity.
-- `Workspace.attachSession(id)` — validates a live or persisted session header cwd against the workspace path and prepends a new id. Unknown sessions, absent/unresolvable/non-directory cwd values, and mismatches reject without writing. `detachSession` removes only the candidate index entry.
-- `Workspace.insertSessionBefore(id, before?)` — moves an accounted session within the manual order, DOM-insertBefore-like: before the anchor, or appended when the anchor is omitted. A session or anchor absent from the account rejects without writing; a move to the current position resolves without writing. Registry Workspace order never changes.
-- `ctx.workspaceRegistry.archiveSession(id)` / `archivedSessionIds` — the registry-global archive set, layered over workspace accounting: an archived session disappears from grouping surfaces but keeps its session log and its `sessionIds` slot, so a future unarchive restores its position. Archiving accepts any live or persisted session (accounted or Ungrouped), resolves without writing for an already archived id, and rejects an unknown id. State written before the field existed parses with an empty set.
-- `Workspace.sessionIds` — synchronous id-plus-canonical-cwd membership projection in durable candidate order. Missing headers, invalid cwd values, and mismatches are filtered; the next workspace mutation prunes them. A medium indexing one session under two workspaces, claiming one path from two records, or diverging from durable workspace order rejects at startup.
-- `Workspace.status()` — uncached directory check, `'ok' | 'missing-dir'`; a missing directory never mutates the record.

-`storageDomain` and `sessionPersistence` are required startup dependencies. An unavailable peer leaves the plugin pending and cannot commit an empty initialized marker. On the first successful start, the registry calls `SessionPersistence.list()` and uses only header `id`, `cwd`, and `createdAt` to group valid historical directories and persist initial order; it never reads event bodies. The initialized marker is written last, so partial bootstrap writes are reused safely after restart. Later cwd-only sessions remain Ungrouped.
+-----
 
-Create and delete persist an explicit pending-mutation marker before their record and order can diverge. Startup completes only the marked mutation, then clears the marker; an unmarked order/table mismatch remains unexplained corruption and fails loud. Deleting and re-registering the same path creates a fresh Workspace id and does not automatically re-adopt the retained Sessions.
+<a id="use-this-package"></a>
+## Use this package
 
+Use this package to give the product a project list: named directories the user works in, the sessions that ran in each, a stable order, and a way to hide sessions without losing them. The API contracts behind each action live in the implementation section.
+
+### When to use it
+
+Use it when the product shows a persistent workspace surface — a sidebar, session grouping, or automation that names directories and orders them. It is invisible to the model, so it adds no token or request cost. Skip it when there is no grouping surface; nothing else in the harness needs it.
+
+### Setting up
+
+The package takes no configuration of its own; it needs a session store, a session persistence backend, and the storage rows that keep its records. A minimal composition:
+
+```yaml
+- name: '@deepseek-ai/dsh-session'
+- name: '@deepseek-ai/dsh-session-persistence-jsonl'
+- name: '@deepseek-ai/dsh-storage'
+- name: '@deepseek-ai/dsh-storage-json'
+- name: '@deepseek-ai/dsh-storage-domain'
+  config:
+    backend: json
+- name: '@deepseek-ai/dsh-workspace'
+```
+
+With these rows mounted, creating a project shows up in the list immediately and survives a restart; the first start also groups existing sessions by the directory they ran in. If a required peer is missing, the workspace feature stays unavailable until it is mounted.
+
+### Creating and ordering projects
+
+Create a project from any directory that exists: give its path and an optional title, and the project appears in the list, newest first. A path that does not exist, or a file instead of a directory, is rejected and nothing changes; creating a project for a directory that already has one returns the existing project unchanged. Rename a project at any time, and move it to any position in the list:
+
+```text
+// Host consumer code, after the composition above is loaded:
+const project = await ctx.workspaceRegistry.create('/path/to/dir', 'My Project')
+await project.setTitle('Renamed')
+ctx.workspaceRegistry.list() // shows the project, newest first
+```
+
+### Grouping sessions under a project
+
+A session joins the project of the directory it runs in: create a session in a project's directory and it appears under that project, newest first. A session can only belong to one project. A session whose directory cannot be validated — no recorded directory, or a moved or deleted folder — cannot join and stays ungrouped.
+
+### Hiding sessions and removing projects
+
+Hide a session from the grouping when it should stop appearing there: it disappears from the visible list, while its session, history, and place in the project stay intact. Remove a project when it is no longer needed: it leaves the list, and its folder, files, and session histories are never touched — those sessions become ungrouped. Adding the same directory again afterwards starts a fresh project without the old sessions.

+## Understand the implementation
+
+<details>
+<summary>Implementation internals — click to expand</summary>
+
+This section explains the design decisions behind the feature and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
+
+### Design philosophy
+
+- **One record per canonical path.** `fs.realpath` is the single uniqueness canon: paths are stored canonicalized, so a symlink to an owned directory collides, and uniqueness is string equality of canonical paths.
+- **Membership is ownership plus a live cwd fact.** The record's ordered `sessionIds` is the ownership truth; the startup header index validates it, and `sessionIds` filters on read while the next mutation prunes durably.
+- **Header-only reads.** Bootstrap and attach validation read `SessionHeader` fields only; event bodies are never loaded.
+- **Two-write mutations with an explicit marker.** Create and delete persist a `pendingMutation` marker before the record/order pair can diverge, so startup completes exactly the interrupted operation and unmarked divergence fails loud as corruption.
+- **Serialized writes.** Registry operations run on one operation chain; entity mutations go through `table.update` on the domain write chain, stamping `updatedAt` and deciding membership at their chain slot.
+
+### API behavior
+
+The API is one small family with two owners: `WorkspaceRegistry` creates, orders, and deletes projects and manages their session accounting; the `Workspace` entity exposes the display title, directory status, and the session projection. Per-method contracts live in the code, not this README — see [src/index.ts](src/index.ts) and [src/entity.ts](src/entity.ts).
+
+### Source map
+
+| File | Role |
+|---|---|
+| [`src/index.ts`](src/index.ts) | Plugin entry: `WorkspaceRegistry` service, header index, bootstrap, operation serialization |
+| [`src/entity.ts`](src/entity.ts) | Package-private `Workspace` implementation and its single `mutate` write path |
+| [`src/spec.ts`](src/spec.ts) | Domain declaration: record schema, registry state, `defineDomain` spec |
+| [`src/types.ts`](src/types.ts) | Public `Workspace` interface and `WorkspaceId` brand |
+| [`src/paths.ts`](src/paths.ts) | The `realpath` uniqueness canon |
+| [`src/invariant.ts`](src/invariant.ts) | Invariant companion: the entity cache mirrors the durable table |
+
+### Durable shape
+
+The registry opens the `workspace` domain (version 2): a `workspaces` table keyed by `WorkspaceId` plus one global state holding `workspaceIds` (the authoritative display order), `archivedSessionIds`, and the optional `pendingMutation` marker. Records written before `archivedSessionIds` existed parse with an empty set through the schema default.
+
+### Lifecycle
+
+On start, the registry opens the domain, completes a marked mutation if one is pending, validates stored state — duplicate paths, duplicate session accounts, and order drift all fail loud — and, when not yet initialized, bootstraps history from persisted headers before writing the initialized marker last, so an interrupted bootstrap resumes safely. A fresh empty registry is real once initialized; it never re-bootstraps.
+
+### Failure and recovery
+
+A create or delete whose second write fails rolls the cache and the prior order back; when both the operation and its rollback fail, the durable marker still names the interrupted operation and the next startup completes or rolls it back. A committed delete whose marker cleanup fails still reports success, and the next startup clears the marker idempotently.
+
+### Invariant
+
+The `workspace-invariant` companion registers the owned relationship: every durable `domain/changed` for the `workspaces` table must name a record the entity cache already holds — a delete is valid only after the registry removed the entity from its cache, so a bypassing write path fails the invariant.

+- **External changes are seen late** — if another process deletes or damages a directory, the project reflects it only at the next refresh or restart.
+- **Archiving is one-way** — a hidden session keeps its history and its place, but no unarchive action exists yet; the archive set is a durable display filter.

-DeepSeek Harness 的 Workspace 实体注册表（`ctx.workspaceRegistry`）：通过领域数据形式存储持久 workspace 记录、稳定 workspace 顺序和按新到旧排列的候选会话索引。消费方看到 `Workspace` 接口；实体实现保持包私有。
+## 概述
 
-实体／存储理由见[领域 Agent Note](../../../.agents/notes/proposed/architecture/2026-07-24-domain-kv-storage-and-workspace.zh.md)；仅使用头部的引导初始化和 GUI 排序见 [Workspace UI 产品流 Agent Note](../../../.agents/notes/implemented/feature/2026-07-25-workspace-ui-product-flow.zh.md)。
+`dsh-workspace` 为宿主提供一组持久 workspace：命名用户目录，每个目录带有在其中运行的会话，并在重启之间保持稳定顺序。借助它，UI 可以显示项目侧边栏、把会话附加到正确的项目、把会话从分组中隐藏而不丢失它，以及移除项目——移除绝不会删除文件夹或会话历史，它们变成 Ungrouped。在需要持久项目分组的 GUI 或宿主组合中使用它；headless 与最小运行可以完全省略它。此包只面向宿主侧：模型、工具与 agent loop 永远不会看到它，因此不会增加任何 token、提示词或请求上下文。它需要会话存储与持久化后端一并挂载；设置只需几行组合配置。
 
-## 结构
+## 目录
 
-- `ctx.workspaceRegistry.create(path, title?)`：规范化 `path` 时使用 `fs.realpath`，拒绝不存在或非目录的路径，每个规范路径最多创建一条记录，并将新记录前置到持久 workspace 顺序。对同一路径重复调用会返回现有 workspace，且不改变其标题；不同路径可以共用显示标题。
-- `ctx.workspaceRegistry.get(id)`/`list()`/`resolveByPath(path)`：由缓存提供的查找。`list()` 为同步操作，并遵循持久注册表顺序；`resolveByPath` 为异步操作，因为它采用相同的 `realpath` 规范化方式，并会拒绝缺失路径，而不是创建路径。
-- `ctx.workspaceRegistry.insertBefore(id, before?)`：在持久注册表顺序内移动一个已注册 Workspace，语义类似 DOM 的 insertBefore：插到锚点之前，省略锚点则追加到末尾。来源或锚点不在注册表中时拒绝且不写入；以自身为锚点或移动到当前位置时直接完成且不写入。返回的 id 列表是完整的已提交顺序。
-- `ctx.workspaceRegistry.delete(id)`：只移除 Workspace 注册记录、对应的持久顺序条目及会话归属记录。未知 id 返回 `false`，成功移除记录则返回 `true`。目录、用户文件、活跃会话和持久化会话日志绝不受影响，因此相关会话会进入 Ungrouped。表写入失败时会恢复原顺序和此前发布的实体。
-- `Workspace.attachSession(id)`：对照 workspace 路径验证实时或已持久化的会话头 cwd，并将新 id 前置。未知会话、缺失／无法解析／非目录的 cwd 值和不匹配情况都会在不写入的前提下被拒绝。`detachSession` 只移除候选索引条目。
-- `Workspace.insertSessionBefore(id, before?)`：在手动顺序内移动一个已记账的会话，语义类似 DOM 的 insertBefore：插到锚点之前，省略锚点则追加到末尾。会话或锚点不在记账中时拒绝且不写入；移动到当前位置时直接完成且不写入。注册表中的 Workspace 顺序绝不改变。
-- `ctx.workspaceRegistry.archiveSession(id)`/`archivedSessionIds`：覆盖在 workspace 记账之上的注册表级全局归档集合：被归档的会话从各分组视图中消失，但其会话日志和 `sessionIds` 席位保持不变，未来取消归档时可恢复原位置。归档接受任何实时或已持久化的会话（无论已记账还是 Ungrouped），对已归档的 id 直接完成而不写入，并拒绝未知 id。在该字段出现之前写入的状态解析为一个空集合。
-- `Workspace.sessionIds`：按持久候选顺序提供同步 id 加规范 cwd 成员投影。缺失头部、无效 cwd 值和不匹配情况都被过滤；下一次 workspace 变更会剪除它们。如果同一存储介质将一个会话索引到两个 workspace 下、用两条记录声明同一路径，或偏离持久 workspace 顺序，启动会被拒绝。
-- `Workspace.status()`：未缓存的目录检查，返回 `'ok' | 'missing-dir'`；目录缺失绝不会改动记录。

-`storageDomain` 和 `sessionPersistence` 是启动必需依赖。任一依赖服务不可用时，插件保持待处理，且不能提交空的已初始化标记。首次成功启动时，注册表调用 `SessionPersistence.list()`，仅使用头部 `id`、`cwd` 和 `createdAt` 对有效历史目录分组并持久化初始顺序；它绝不读取事件正文。已初始化标记最后写入，因此重启后可安全复用引导初始化期间的部分写入。后续仅能通过 cwd 识别的会话仍属于 Ungrouped。
+-----
 
-创建和删除操作会在记录和顺序可能分叉之前，先持久化明确的待处理变更标记。启动时只补全该标记所指明的变更，随后清除标记；没有标记的顺序／表不一致仍属于来源不明的损坏，并会明确报错。删除后重新注册同一路径会生成新的 Workspace id，且不会自动重新接纳保留下来的会话。
+<a id="use-this-package"></a>
+## 使用本包
 
+使用此包为产品提供项目列表：用户工作的命名目录、每个目录中运行的会话、稳定顺序，以及在不丢失会话的前提下将其隐藏的能力。每项操作背后的 API 约定放在实现章节中。
+
+### 何时使用
+
+当产品展示持久 workspace 界面——侧边栏、会话分组或需要命名并排序目录的自动化——时使用它。它对模型不可见，因此不增加任何 token 或请求成本。没有分组界面时跳过它；harness 中没有其他包需要它。
+
+### 设置
+
+此包本身不声明任何配置；它需要会话存储、会话持久化后端，以及保存其记录的存储行。最小组合如下：
+
+```yaml
+- name: '@deepseek-ai/dsh-session'
+- name: '@deepseek-ai/dsh-session-persistence-jsonl'
+- name: '@deepseek-ai/dsh-storage'
+- name: '@deepseek-ai/dsh-storage-json'
+- name: '@deepseek-ai/dsh-storage-domain'
+  config:
+    backend: json
+- name: '@deepseek-ai/dsh-workspace'
+```
+
+挂载这些行之后，创建项目会立即出现在列表中并在重启后保留；首次启动还会按会话运行的目录对既有会话分组。如果缺少某个必需依赖，workspace 功能会一直不可用，直到它被挂载。
+
+### 创建与排序项目
+
+从任何存在的目录创建项目：给出路径和可选标题，项目即出现在列表中，新到旧排列。不存在的路径或文件而非目录会被拒绝，且不会有任何变化；为已有项目的目录再次创建会原样返回现有项目。你可以随时重命名项目，并把它移动到列表中的任意位置：
+
+```text
+// Host consumer code, after the composition above is loaded:
+const project = await ctx.workspaceRegistry.create('/path/to/dir', 'My Project')
+await project.setTitle('Renamed')
+ctx.workspaceRegistry.list() // shows the project, newest first
+```
+
+### 将会话归入项目
+
+会话加入它运行目录所在的项目：在项目目录中创建会话，它就会出现在该项目下，新到旧排列。一个会话只能属于一个项目。目录无法校验的会话——没有记录目录，或目录被移动、删除——无法加入，保持 Ungrouped。
+
+### 隐藏会话与移除项目
+
+当会话不应再出现在分组中时隐藏它：它会从可见列表中消失，但其会话、历史与在项目中的位置都保持不变。项目不再需要时移除它：它离开列表，而其文件夹、文件与会话历史绝不受影响——这些会话变成 Ungrouped。之后再次添加同一目录会从空项目开始，不会带回旧会话。

+
+<details>
+<summary>实现细节——点击展开</summary>
+
+本节解释此功能背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
+
+### 设计理念
+
+- **每个规范路径一条记录。** `fs.realpath` 是唯一的一套唯一性规范：路径以规范化形式存储，因此指向已被拥有目录的符号链接会与之冲突，唯一性即规范路径的字符串相等。
+- **成员资格是所有权加实时 cwd 事实。** 记录的 `sessionIds` 顺序是所有权真源；启动时的头部索引校验它，`sessionIds` 在读取时过滤，下一次变更持久剪除。
+- **仅读取头部。** 引导与 attach 校验只读取 `SessionHeader` 字段；事件正文绝不加载。
+- **两次写入的变更带显式标记。** 创建与删除在记录/顺序对可能分叉之前先持久化 `pendingMutation` 标记，因此启动只补全被中断的操作，未标记的分叉作为损坏明确报错。
+- **串行化写入。** 注册表操作跑在同一条操作链上；实体变更通过领域写链上的 `table.update` 执行，盖上 `updatedAt` 并在其链槽决定成员资格。
+
+### API 行为
+
+该 API 是一个由两个所有者构成的小家族：`WorkspaceRegistry` 负责创建、排序与删除项目并管理其会话记账；`Workspace` 实体暴露显示标题、目录状态与会话投影。各方法的精确约定在代码中，而非本 README——参见 [src/index.ts](src/index.ts) 与 [src/entity.ts](src/entity.ts)。
+
+### 源码地图
+
+| 文件 | 职责 |
+|---|---|
+| [`src/index.ts`](src/index.ts) | 插件入口：`WorkspaceRegistry` 服务、头部索引、引导、操作串行化 |
+| [`src/entity.ts`](src/entity.ts) | 包私有 `Workspace` 实现及其唯一的 `mutate` 写入路径 |
+| [`src/spec.ts`](src/spec.ts) | 领域声明：记录 schema、注册表状态、`defineDomain` 规范 |

+| [`src/paths.ts`](src/paths.ts) | `realpath` 唯一性规范 |
+| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件：实体缓存镜像持久表 |
+
+### 持久形态
+
+注册表打开 `workspace` 领域（版本 2）：一张以 `WorkspaceId` 为键的 `workspaces` 表，加上一个持有 `workspaceIds`（权威显示顺序）、`archivedSessionIds` 与可选 `pendingMutation` 标记的全局状态。在 `archivedSessionIds` 存在之前写入的记录会通过 schema 默认值解析为空集合。
+
+### 生命周期
+
+启动时，注册表打开领域、若存在标记则补全被标记的变更、校验已存状态——重复路径、重复会话账本与顺序漂移都会明确报错——并在尚未初始化时先凭持久化头部引导历史、最后写入已初始化标记，因此被中断的引导可以安全恢复。全新空注册表一旦初始化即为真，绝不会再次引导。
+
+### 失败与恢复

+创建或删除的第二次写入失败时，缓存与先前顺序会回滚；当操作与回滚都失败时，持久标记仍指明被中断的操作，下一次启动会补全或回滚它。已提交的删除即使标记清理失败仍报告成功，下一次启动会幂等地清除该标记。
+
+### 不变式
+
+`workspace-invariant` 伴生插件注册归属关系：`workspaces` 表的每个持久 `domain/changed` 都必须指向实体缓存已持有的记录——只有在注册表从缓存移除实体之后删除才有效，因此绕过注册表的写入路径会触发不变式失败。

+- **移除绝不删除数据**——移除项目会保留其文件夹、文件与会话历史；这些会话变成 Ungrouped，而会话删除与文件夹移除是彼此独立且尚未提供的功能（参见[决策记录](../../../.agents/notes/implemented/feature/2026-07-27-workspace-registration-deletion.zh.md)）。
+- **只有带记录目录的会话才能加入**——只有记录中带有可解析为项目路径的目录的会话才属于项目；没有目录的会话保持 Ungrouped，来自其他目录的会话无法移入。
+- **外部变更延迟可见**——如果另一进程删除或损坏目录，项目只能在下次刷新或重启后反映出来。
+- **归档是单向的**——被隐藏的会话保留其历史与位置，但目前没有取消归档操作；归档集合是持久的显示过滤器。
+- **重新添加目录从空开始**——移除后再次添加同一目录会创建空会话列表的新项目；旧会话不会自动回来。

 Separate runtime and SDK jobs let an SDK upload failure resume without resending immutable runtime files. They accept `publish=true` only when the workflow runs from the configured publisher repository at the matching `python-v*` tag and the protected `pypi-runtime` and `pypi` environments approve the runtime and SDK jobs, respectively. PyPI Trusted Publishing still supplies short-lived OIDC credentials, but public attestations are disabled because they would disclose the private publisher identity.

+# @deepseek-ai/dsh-agent-team-profile
+
+English | [中文](README.zh.md)
+
+Private profile bundle that enables [Agent Teams](../team/README.md) over `@deepseek-ai/dsh-base`. Its patch inserts the Team domain and scoped tools, disables the overlapping global continuable-child controls, and keeps the ordinary fresh and fork delegation tools as one-shot operations. Install this package explicitly into a source-checkout profile; it is excluded from official releases.
+
+## Profile installation
+
+From this repository checkout, add the package to an initialized profile:
+
+```sh
+pnpm dsh plugin --profile headless add ./packages/experimental/agent-team-profile
+pnpm dsh --profile headless "Use Agent Teams to split this task between two teammates, wait, and summarize."
+```
+
+The profile must already contain `@deepseek-ai/dsh-base`, whose Subagent services and provider rows this layer consumes. Removing the package with `dsh plugin --profile <name> remove @deepseek-ai/dsh-agent-team-profile` removes the bundle from the profile's ordered layer list.
+
+## Model Experience
+
+### Team policy and tools
+
+#### What the model sees
+
+The Team policy and schemas belong to [`@deepseek-ai/dsh-tool-team`](../tool-team/README.md). This bundle changes composition only: Team-scoped `list_agents` and `send_message` replace the disabled global continuable-child controls, while `subagent` and `subagent_fork` remain available as one-shot delegation tools.
+
+#### Token effect
+
+The bundle adds the Team policy and tool schemas described by `dsh-tool-team`; it adds no prompt text of its own.
+
+#### KV Cache effect
+
+The bundle's composition is prefix-stable while its patch, Team identity, and configured tool schemas remain unchanged.
+
+## Known Limitations and Deferred Work
+
+- **Source-checkout only** — this private package is not present in official npm, CLI, Web, or Python release payloads.
+- **Shared checkout** — every teammate observes the same working directory; this bundle adds no worktree isolation or filesystem locking.

+# @deepseek-ai/dsh-agent-team-profile
+
+[English](README.md) | 中文
+
+在 `@deepseek-ai/dsh-base` 之上启用 [Agent Teams](../team/README.md) 的私有 profile bundle。它的 patch 会插入 Team domain 与 scoped 工具、禁用名称重叠的全局 continuable-child control，并保留普通的一次性 fresh／fork delegation 工具。必须从源码 checkout 将本包显式安装到 profile；正式发布会排除本包。
+
+## Profile 安装
+
+在本仓库 checkout 中，将本包添加到已初始化的 profile：
+
+```sh
+pnpm dsh plugin --profile headless add ./packages/experimental/agent-team-profile
+pnpm dsh --profile headless "Use Agent Teams to split this task between two teammates, wait, and summarize."
+```
+
+profile 必须已经包含 `@deepseek-ai/dsh-base`，本层会使用其中的 Subagent service 与 provider 配置行。执行 `dsh plugin --profile <name> remove @deepseek-ai/dsh-agent-team-profile` 移除本包时，bundle 也会从 profile 的有序层列表中移除。
+
+## Model Experience
+
+### Team 策略与工具
+
+#### 模型会看到什么
+
+Team 策略与 schema 由 [`@deepseek-ai/dsh-tool-team`](../tool-team/README.md) 所有。本 bundle 只改变 composition：Team-scoped `list_agents` 与 `send_message` 会替代已禁用的全局 continuable-child control，而 `subagent` 与 `subagent_fork` 仍作为一次性 delegation 工具可用。
+
+#### Token 影响
+
+本 bundle 会加入 `dsh-tool-team` 描述的 Team 策略与工具 schema；它自身不增加提示词文本。
+
+#### KV Cache 影响
+
+只要 bundle patch、Team identity 与配置的工具 schema 不变，本 bundle 的 composition 就保持前缀稳定。
+
+## Known Limitations and Deferred Work
+
+- **仅限源码 checkout**：正式 npm、CLI、Web 与 Python 发布产物都不包含这个私有包。
+- **共享 checkout**：所有 teammate 都观察同一个工作目录；本 bundle 不提供 worktree 隔离或文件系统锁。

-Package tests cover identity, name and authority checks, provider selection, reserved-id persistence collisions, child-before-Lead flush ordering, durable provisioning failure and pending-inbox JSONL/SQLite reconciliation, concurrent target-local ordering, pending/history de-duplication, mailbox limits, post-flush notification, bounded disposal with in-flight creation and dispatch cancellation, failed-member cleanup, task CAS and DAG validation, write-scope warnings, wait cancellation/timeout, inbox-preserving interruption, ordinary-fork isolation, legacy-control shadowing, compact declared-schema result rendering, and scoped registration HMR at per-file 100% coverage. A keyless headless Loader snapshot assembles the real Team plugins and exercises two teammates, dependent tasks, peer delivery, waiting, completion, and Lead aggregation. A CLI product test loads the private Agent Teams profile bundle, starts `dsh run` through the real Loader and direct core front door, and verifies normal process exit with persisted Team and child logs.

 ## Decision
 
-`packages/experimental/agent-team` and `packages/experimental/tool-agent-team` are private workspace packages. The [experimental package naming decision](2026-08-19-experimental-package-name-prefix.md) owns their npm names and promotion rename; this note owns their placement, release exclusion, and dependency isolation.
+`packages/experimental/agent-team`, `packages/experimental/tool-agent-team`, and `packages/experimental/agent-team-profile` are private workspace packages. The [experimental package naming decision](2026-08-19-experimental-package-name-prefix.md) owns their npm names and promotion rename; this note owns their placement, release exclusion, and dependency isolation.
 
 The dsh pack and publish set and the local baseline publisher exclude every manifest below `packages/experimental/`. `release:dsh` still advances their manifest versions with the shared dsh version without creating release tags. Workspace constraints require each experimental package to set `private: true` and omit `publishConfig`. The same top-level check rejects `dependencies`, `optionalDependencies`, and `peerDependencies` from release packages, release apps, or the Python runtime to an experimental package. Experimental packages may depend on release packages and each other; tests may use them through `devDependencies`, and examples may load them explicitly.
 
 The generic caller-reserved continuable child identity and selective direct-child drain remain in the stable Subagent service. They own Subagent identity and Activation lifecycle without importing or naming Agent Teams; the experimental Team service consumes them in the permitted direction.
 
+The private Agent Teams profile bundle depends on the Team packages and applies after `dsh-base`. It inserts the Team rows, disables the global continuable-child controls whose model-visible names overlap the Team tools, and leaves the shipped base, CLI, Web, and Python runtime dependency graphs unchanged.
+
+Profile startup resolves selected bundles before healing module fallbacks. The shared fallback retains the dsh installation's carrier-specific entries: symlinks under plain Node and ESM proxies in a packaged executable. Missing packages from selected bundle closures are linked under the current profile's own `node_modules`, while pnpm-managed profile entries remain authoritative. Closure discovery starts from each explicit external bundle's real package directory and traverses every listed root even when an earlier dependency has the same package name. It excludes dsh-owned profile projections from later discovery, so a projected dependency cannot feed back into its own closure. Link ownership compares canonical parent paths so junction-normalized targets remain removable. A private profile layer can therefore carry experimental plugin rows without adding those plugins to a release app, requiring profile users to install transitive packages directly, weakening packaged-runtime module identity, or changing another profile's resolution.
+
 Experimental status changes publication and compatibility expectations only. The packages retain the repository's ordinary documentation, invariant, lifecycle, security, unit, real-composition, and snapshot requirements. Promotion requires review of the public contracts, limitations, test evidence, release payload, runtime dependents, and a named owner accepting stable-package obligations.

+Agent Teams can use the full repository graph and quality checks without entering official tarballs or becoming a supported runtime dependency. A release package cannot expose Team until the Team packages are promoted, so the CLI experiment installs an explicit private profile layer instead of changing shipped bundles. The generic profile launcher accepts that layer without making its plugin dependencies part of the dsh release closure.
 
 The product-role grouping is less direct while the packages incubate. Promotion creates path and npm-name churn as specified by the experimental package naming decision.

 dsh pack 与 publish 集合以及本地 baseline 发布器均排除 `packages/experimental/` 下的所有 manifest。`release:dsh` 仍会让这些 manifest 跟随 dsh 共享版本递增，但不会创建发布 tag。workspace 约束要求每个实验性包设置 `private: true` 并省略 `publishConfig`。同一个顶层检查会拒绝发布包、发布 app 或 Python runtime 通过 `dependencies`、`optionalDependencies` 或 `peerDependencies` 依赖实验性包。实验性包可以依赖发布包和其他实验性包；测试可以通过 `devDependencies` 使用它们，示例可以显式加载它们。
 
 通用的调用方预留 continuable child 身份和精确 direct-child drain 仍属于稳定 Subagent 服务。它们负责 Subagent 身份与 Activation 生命周期，不 import 或命名 Agent Teams；实验性 Team 服务沿允许的方向消费这些能力。
 
+私有 Agent Teams profile bundle 依赖 Team 包，并应用在 `dsh-base` 之后。它插入 Team 配置行，禁用模型可见名称与 Team 工具重叠的全局 continuable-child control，并保持已发布 base、CLI、Web 与 Python runtime 的依赖图不变。
+
+profile 启动会先解析所选 bundle，再修复模块 fallback。共享 fallback 保留 dsh 安装的载体专用条目：普通 Node 下使用 symlink，打包 executable 中使用 ESM proxy。仅由所选 bundle 闭包携带的缺失包会链接到当前 profile 自己的 `node_modules` 下，而 pnpm 管理的 profile 条目仍具有优先权。闭包发现从每个显式外部 bundle 的真实包目录开始；即使前一个依赖具有相同包名，也会遍历所有列出的根。后续发现会排除 dsh 所有的 profile projection，避免投影后的依赖重新进入自己的闭包。link ownership 通过规范化父路径比较，使 junction 规范化后的 target 仍可删除。因此，私有 profile 层可以携带实验性 plugin 配置行，而无需把这些 plugin 加入发布 app、要求 profile 用户直接安装传递依赖、破坏 packaged-runtime 的模块身份，或改变其他 profile 的解析结果。
+
 实验性状态只改变发布与兼容性预期。这些包仍须满足仓库的一般文档、不变式、生命周期、安全、单元测试、真实组合测试和快照要求。promotion 前必须评审公开约定、限制、测试证据、发布 payload、运行时依赖方，并由一名具名 owner 接受稳定包义务。

 - **Channel-neutral library.** The package carries no loader hooks and no dev-mode surface; the [`dsh` app](../../../apps/cli/README.md) owns its Node source-launch hook and consumes these helpers for the boot sequence, and built consumers use plain Node package resolution.
 - **Two Loader builtins.** `mountRootInclude` registers `cordis:include` and `cordis:group` as Loader builtins: a group row gives one `isolate` realm to a provider and its consumers together, and an agent preset outside this workspace cannot resolve `@deepseek-ai/cordis-plugin-group` by name. Both load through the ambient module pipeline rather than the included tree's own specifier resolution.
-- **Profile module fallback.** Bare plugin specifiers resolve through the Loader from the config directory. Plain Node maintains one symlink per package in the installation dependency closure. A packaged executable instead reads each installed export map with Node ESM conditions and writes real proxy packages that re-export virtual module URLs, because an operating-system symlink cannot enter pkg's `/snapshot` tree. Missing exports stay unavailable, malformed maps fail startup, and a cross-process writer lock replaces stale entries without exposing partial proxies.

Missing exports stay unavailable, malformed maps fail startup, and a cross-process writer lock replaces stale entries without exposing partial proxies. A selected external bundle absent from the installation closure receives a profile-local `.dsh-module-fallback` link; existing pnpm entries win, projected links are excluded from later closure discovery, and cleanup removes only dsh-owned links.
 - **One rejection checkpoint.** `assertEntriesActivated` keeps the exact reasons it folds into the boot diagnostic visible through the next process rejection checkpoint, so `installFailLoud` coalesces Loader's duplicate notification while unrelated unhandled rejections remain fatal.
 - **Two-stage failure labels.** `boot()` distinguishes `host preparation failed` — `prepare` threw before any config-tree entry mounted — from `plugin tree failed to load`, and appends the deepest plugin error's stack so the startup diagnostic preserves the original activation error instead of only the wrap chain.

 - **单一 rejection 检查点。** `assertEntriesActivated` 把折入启动诊断的确切原因保持到下一个进程级 rejection 检查点可见，使 `installFailLoud` 能合并 Loader 的重复通知，而所有无关的未处理 rejection 仍然致命。
 - **两阶段失败标签。** `boot()` 区分 `host preparation failed`（`prepare` 在任何配置树条目挂载前抛出）与 `plugin tree failed to load`（此后的一切失败），并追加最深层插件错误的堆栈，使启动诊断保留原始激活错误，而不只是包装链。

- * exports under ESM import conditions and writes small proxy packages because

- * partial proxies and carrier transitions remain serialized. Node's
- * parent-directory walk from any profile finds this
- * directory after the profile's own `node_modules`, so every in-box plugin
- * resolves without pnpm ever managing it — the exact "bundles come from the
- * installation" contract. The closure (not just direct dependencies) is
- * required for out-of-tree plugins: their peer dependencies name Service
- * Definition packages (`dsh-compaction`, `dsh-invariants`, ...) that the app
- * reaches only through its Service Provider packages. Both a symlink target
- * and a proxy's virtual target resolve transitive imports from the original
- * package directory, so each package needs one flat fallback entry.
- * Idempotent: correct entries are kept and changed installation targets are
- * rewritten; under plain Node, a stale dangling link stays until its name is
- * reused because resolution cannot discover it.
- * @param installAnchor - absolute path of the dsh app's package.json.
- * @param home - the Harness home; defaults to {@link resolveDshHome}.

+ * closure. Plain Node writes symlinks; a packaged executable writes ESM
+ * proxies under a cross-process lock because operating-system links cannot
+ * enter pkg's virtual filesystem. Missing packages carried only by selected
+ * bundles are linked through a profile-owned directory into that profile's
+ * `node_modules`; pnpm-managed entries remain authoritative, and another

-# Agent Note: Session log versioning — one integer, an upgrade chain, and a per-event ignorable marker
-
-Status: implemented
-
-English | [中文](2026-08-10-session-log-version-mechanism.zh.md)
-
-## Problem
-
-Session logs must be upgradable after release, and the runtime that ships first is the floor for every later decision: whatever refusal and degradation behavior is missing from the first released reader can never be added to the copies users already run. Release issue #1901 required at minimum that an old runtime reading a newer session format reports "unsupported" instead of misreading it. The pre-change reader did the opposite on both axes: `assertVersion` rejected any version mismatch with one direction-blind message, and the JSONL decoder passed unknown event types through untouched, so reconstruction silently skipped them — resuming a gutted session with no diagnostic at all.
-
-## Decision
-
-**One monotonic integer, no major/minor split.** Whether a version step is auto-upgradable is a property of that step — expressed by whether its upgrader exists — not something a two-level numbering scheme should promise in advance (you rarely know at design time whether the next change will turn out "major"). This matches the SQLite backend's `SCHEMA_VERSION` precedent.
-
-**The writer decides bumps, not the reader.** A bump is required exactly when an old runtime could no longer handle a new log with full semantic correctness. "Parses without error" is not the bar: silently skipping content that shapes reconstruction is a wrong read. Only structural changes qualify — header shape, event envelope, core event semantics, the surface mechanism (`SurfaceEventType` set, `SurfaceOp` variants). When unsure, bump: a near-identity upgrader is almost free, a missed bump silently corrupts old readers.
-
-**Read rules by direction.** Equal version: read normally. Newer than the reader: refuse, name the direction ("written by a newer harness — upgrade"), and point at the raw log artifact so the user can still see the text (`SessionFormatUnsupportedError`, distinct from `SessionPersistenceCorruptionError` because nothing is damaged). Older than the reader: convert in memory through the chain of n→n+1 upgraders for viewing; persist the converted log only when the session is actually continued (atomic temp-file replace, original kept as backup). A step whose upgrader cannot be written is left empty, which cuts off every version at or below it — those degrade to raw-text viewing.
-
-**A per-event `ignorable` marker covers vocabulary growth, so ordinary event additions never bump the version.** The event vocabulary is decided by which plugins are mounted, which a single version integer cannot describe. A reader meeting an unrecognized event type refuses to interpret the log unless the event carries `ignorable: true` in its envelope. The default is *required*: forgetting the marker over-refuses a resumable session (an inconvenience), while a default of ignorable would make the same mistake silently resume a gutted one (a safety failure). The architecture makes this sound: model-visible content flows only through the three `surfaceOp`-marked surface event types plus the `request/header`/`request/context` folds, so the dangerous unknowns are exactly the non-surface events that change how the rest of the log is read (`session/end-seed` is the existing example).
-
-## Consequences
-
-What shipped in v0 (release 0812): direction-aware refusal with the raw-log path; the unknown-event guard against a generated known-vocabulary list (`KNOWN_SESSION_EVENT_TYPES`, emitted by `gen-persistence-catalog` from every `SessionEventMap` merge and kept fresh by `verify-persistence-catalog`); the `ignorable` envelope field accepted by seed validation, both backends (a dedicated SQLite column, `SCHEMA_VERSION` 15), and the BFF wire schema. The upgrader chain itself is deferred until the first real v0→v1 step exists to test it against; writers do not yet set `ignorable` (no producer needs it), so `Session.append` gains that surface with its first user. Until a registration surface exists, an out-of-repo plugin's events refuse resume under first-party readers — the pre-release stance accepts that, and the refusal is loud rather than silent. The unknown-type guard is read-side only: `appendCore` keeps rejecting retired legacy shapes but does not vocabulary-check new types, because an append-time refusal would stall a live session's durability mid-flight, which costs more than a loud refusal at the log's next load. The JSONL backend additionally refuses a foreign version from the raw header line before validating this format version's header shape or decoding any event row, so a structurally different future format still reports the upgrade direction instead of "corrupt"; SQLite gates whole-file structure through its own `SCHEMA_VERSION` pragma first.
-
-## Alternatives considered
-
-- **Major/minor versioning** — the "is it convertible" bit lives on each step's upgrader, and pre-committing it into a number shape invites wrong promises.
-- **Default-ignorable unknown events** — inverts the failure mode of a forgotten marker from visible over-refusal into silent corruption.
-- **Auto-migrating on view** — rewriting the artifact on open turns a read into a destructive write: a converter bug corrupts logs at browse time, and a same-directory older runtime loses access because a newer one merely looked.
-- **Per-plugin runtime registration of known event types** — would make the known set composition-dependent, so a leaner same-version composition would refuse logs a fuller one wrote. The generated repo-wide list keeps same-version reads uniform; out-of-repo plugin events are outside it by construction, and a registration surface for them is deferred until such a consumer exists.

-# Agent Note: Session log 版本机制：单调整数、升级器链、逐事件可忽略标记
-
-Status: implemented

-## 问题
-
-Session log 在发布后必须能升级格式，而最先发布的运行时决定了此后一切的下限：第一个发布版的读取器缺少哪种拒绝和降级行为，用户手里已经装上的副本就永远补不上。发布 issue #1901 的最低要求是老运行时读到新 Session 格式时明确报不支持，而不是读错。改动前的读取器在两个方向上都做反了：`assertVersion` 对任何版本不匹配抛出同一条不区分方向的消息；JSONL 解码器把不认识的事件类型原样放行，重建时静默跳过，恢复出一个内容残缺的会话且没有任何诊断。
-
-## 决定
-
-**一个单调递增的整数，不分大小版本。**某一步能不能自动升级是那一步自己的属性，由它的升级器存在与否表达，不该由两级编号方案提前承诺（设计时很少能预知下一个变更算不算"大"）。这与 SQLite 后端 `SCHEMA_VERSION` 的先例一致。
-
-**升不升版本由写入方决定，与读取方能力无关。**当且仅当老运行时无法在语义上完全正确地处理新日志时才必须升版本。"解析不报错"不是标准：静默跳过影响重建的内容就是读错。只有结构性变更够得上这条线：header 形状、事件信封、核心事件语义、surface 机制（`SurfaceEventType` 集合、`SurfaceOp` 变体）。拿不准就升：近似恒等的升级器几乎没有成本，漏升一次会让老读取器静默读坏。
-
-**读取规则按方向区分。**版本相等：正常读。比读取器新：拒绝，说明方向（"由更新的 harness 写入，请升级"），并给出原始日志文件的路径，用户仍能看到文本（`SessionFormatUnsupportedError`，与 `SessionPersistenceCorruptionError` 区分，因为数据没有损坏）。比读取器旧：查看时经 n→n+1 升级器链在内存中逐级转换；只有会话真正被继续时才把转换落盘（临时文件原子替换，原文件留备份）。写不出升级器的那一步留空，这会切断该步及更早所有版本的升级路径，它们降级为只能看原文。
-
-**逐事件的 `ignorable` 标记吸收词汇表增长，普通的新增事件永远不用升版本。**事件词汇表由挂载了哪些插件决定，单个版本整数描述不了它。读取器遇到不认识的事件类型时拒绝解读日志，除非该事件的信封带 `ignorable: true`。默认为必需：忘写标记的后果是把一个本可恢复的会话拒绝过头（体验问题），而默认可忽略会让同样的疏忽静默恢复出残缺会话（安全事故）。架构保证了这条规则成立：模型可见内容只经三种带 `surfaceOp` 标记的 surface 事件加 `request/header`、`request/context` 折叠进入重建，危险的未知事件恰好是那些不进 surface 但改变日志其余部分解读方式的事件（`session/end-seed` 是现存例子）。
-
-## 影响
-
-v0（0812 发布）交付的内容：分方向的拒绝并带原始日志路径；基于生成的已知词汇清单（`KNOWN_SESSION_EVENT_TYPES`，由 `gen-persistence-catalog` 从所有 `SessionEventMap` 声明合并生成，`verify-persistence-catalog` 保证新鲜）的未知事件守卫；`ignorable` 信封字段被种子校验、两个后端（SQLite 专用列，`SCHEMA_VERSION` 升到 15）和 BFF 线上 schema 接受。升级器链本身推迟到第一个真实的 v0→v1 变更出现、有真实对象可测时再建；写入侧目前不写 `ignorable`（还没有生产者需要它），`Session.append` 的这一表面随第一个使用者一起落地。在注册表面出现之前，仓库外插件的事件在第一方读取器下无法恢复会话，预发布立场接受这一点，而且拒绝是显式的而非静默的。未知类型守卫只在读取侧生效：`appendCore` 继续拒绝已淘汰的 legacy 形状，但不对新类型做词汇检查，因为写入时拒绝会让活跃会话的持久化中途停摆，代价大于下次加载时的显式拒绝。JSONL 后端还会在校验本格式版本的 header 形状、解码任何事件行之前，直接从原始 header 行拒绝外来版本，因此结构完全不同的未来格式仍会报告升级方向而不是"损坏"；SQLite 则先由自己的 `SCHEMA_VERSION` pragma 把关整个文件的结构。
-
-## 曾考虑的替代方案
-
-- **大小两级版本号**：能否转换这一位信息属于每一步的升级器，把它预先固化进编号形状会做出错误承诺。
-- **未知事件默认可忽略**：把忘写标记的后果从可见的过度拒绝反转成静默损坏。
-- **查看时自动迁移落盘**：打开即改写把读操作变成破坏性写操作，转换器的 bug 会在浏览时损坏日志，同目录的旧版本运行时也会因为新版本只是看了一眼就失去访问能力。
-- **插件运行时注册已知事件类型**：会让已知集依赖插件组合，同版本的精简组合会拒绝完整组合写出的日志。生成的全仓库清单保证同版本读取行为一致；仓库外插件的事件按构造就在清单之外，为它们提供注册表面推迟到真有这样的消费者时再做。

-Schema 17 keeps ordinary ROWID tables and the composite `events(session_id, seq)` primary-key index. Scalar rows represent one logical event. Packed rows use the storage tags `text-chunks`, `reasoning-chunks`, and `tool-call-chunks`; the SQL `seq` and `time` columns hold the first logical member, and `data` holds the packed payload. Packed rows set `ignorable=0` as a physical discriminator and leave `source_event_seqs` and `surface_op` as `NULL`; scalar rows use `ignorable=1` only for logical ignorable events and `NULL` otherwise. A future ignorable logical event may therefore reuse a storage-tag name without being decoded as a packed row. The tags are storage vocabulary, not `SessionEventMap` members.

The tags are storage vocabulary, not `SessionEventMap` members.
 
-SQLite owns chunk encoding and validation inside the schema-17 package. Exact-field whitelisting means unknown fields, surface metadata, incompatible chunk identity, sequence gaps, and unsafe timestamps remain scalar rather than losing information. One packed row represents at most 1,024 events and 1 MiB of uncompressed UTF-8 `data`; the encoder partitions longer runs, and the decoder rejects rows outside those format limits.

 The `data` column accepts `TEXT` or `BLOB`. Serialized values below 4 KiB remain text. At or above the threshold, the writer uses Zstandard level 3 and retains the frame only when it is smaller than the text; the reader decompresses the blob before strict UTF-8 decoding and JSON parsing. The fixed moderate level and threshold limit frame overhead and synchronous CPU work while capturing the repeated payloads that dominate retained bytes.
 
-`source_event_seqs` remains the complete ordered list of earlier events cited by a surface node, including every streamed chunk behind an assembled assistant message. Schema 17 stores the first sequence as an unsigned varint and every subsequent signed difference as a ZigZag varint. This preserves arbitrary order and every sequence while exploiting the overwhelmingly consecutive lists produced by streaming. An empty list is an empty non-null blob, distinct from absent provenance.

 ### Transactional append packing
 
@@ -32,11 +32,11 @@ Normal append never deletes or replaces an earlier event row. Fixed write-behind
 
 Full reads decode each physical row as one all-or-nothing logical span and validate contiguous logical sequences. A reverse pass identifies the last valid `turn/end` without retaining a second decoded copy of the full physical scan; the forward pass decodes one row at a time into the required logical result. A malformed row or gap before that committed boundary is corruption; a malformed final physical row becomes the opaque repair marker at that row's base sequence. Recovery re-reads and validates that marker while holding the write lock, then deletes the whole physical row and any later rows before binding synthetic closers as scalar events. A stale repair cannot delete a newer writer's valid suffix.
 
-`readFrom(id, fromSeq)` examines packed predecessors only within the maximum schema-17 row span, then reads from the earliest candidate that may contain `fromSeq`. The decoder filters reconstructed members below `fromSeq`, so a suffix may begin inside a packed row without parsing an unrelated earlier scalar row. Reading from that candidate also exposes an overlapping scalar row to contiguity validation instead of letting it hide the packed member. Packed data exceeding the uncompressed format byte limit rejects before JSON parsing.

After selecting and verifying the journal mode, the provider pins `synchronous=FULL` and verifies it so SQLite build defaults cannot weaken committed-append durability. Package code loads every statement and fixed pragma from closed-name `.sql` resources and binds runtime values as parameters.

+# Agent Note: Require known session event types on read
+
+Status: implemented
+
+English | [中文](2026-08-25-fail-closed-session-event-vocabulary.zh.md)
+
+## Problem
+
+A session reader must not silently omit a durable event it does not understand. An unknown event can change later request reconstruction, policy state, recovery, or another plugin-owned projection, so successful JSON parsing is not enough to establish a faithful read. The reader before [issue #1901](https://github.com/deepseek-ai/deepseek-harness/issues/1901) passed unknown event types through while core folds ignored them, allowing a resumed session to lose semantics without a diagnostic.
+
+The first refusal mechanism combined a generated known-event set with an optional per-record `ignorable: true` assertion intended for informational event additions. No production writer used the assertion, and `Session.append()` did not expose a way to set it. Event types added after the mechanism remained required-on-read. The unused field nevertheless expanded the canonical event type, seed validation, persistence formats, SQLite schema, session transport, DeepSeek request extension, generated catalogs, documentation, and tests.
+
+## Decision
+
+Every session event type is required-on-read. After supported legacy records are normalized, `PersistenceCoordinator` compares each event type with `KNOWN_SESSION_EVENT_TYPES`, the generated set of every `SessionEventMap` member declared in this repository. Any unknown type refuses reconstruction with `SessionFormatUnsupportedError`; the diagnostic names the event and sequence, identifies the likely newer writer, and includes the raw artifact path when the backend has one. The guard remains read-side only because rejecting an append after a live event is committed would interrupt durability before the session can report the unsupported log on its next load.
+
+`SessionEvent` has no optional unknown-event skip field. JSONL continues to serialize the same event objects because no production append path emitted that field, and `SESSION_FORMAT_VERSION` remains `0`. The SQLite provider replaces the overloaded `ignorable` column with the schema-18 `is_packed` discriminator: scalar logical events store `0`, packed chunk rows store `1`, and an event name equal to a physical chunk tag remains unambiguous before the coordinator applies the known-type guard.
+
+`SESSION_FORMAT_VERSION` remains one monotonic integer. A writer bumps it when an older runtime cannot interpret a structural or semantic change with full correctness: session header fields, event envelope fields, core event semantics, or the `SurfaceEventType`/`SurfaceOp` mechanism. Adding an event type alone does not require a bump because an older reader refuses that exact unknown type instead of misreading the log. Equal versions read normally; unequal versions currently refuse with a directional diagnostic. The n→n+1 upgrader chain remains deferred until a real v0→v1 step provides an input and output to test. A future view upgrade belongs in memory, with durable replacement only when the user continues the session; a missing step leaves the source artifact available for raw viewing.
+
+Repository-external `SessionEventMap` members remain outside the generated set. They can run and persist during the live process, but a first-party persistence reader refuses them on reload until a real external-event consumer justifies a registration mechanism. This preserves the existing loud pre-release limitation without a composition-dependent known set.
+
+## Alternatives considered
+
+**Keep the per-record skip assertion.** Rejected because it has no production producer, is not expressible through `Session.append()`, and requires every storage and transport representation to preserve a speculative choice. A real need should first define which event type is safe to omit, then make the append implementation emit that classification consistently instead of relying on each call site.
+
+**Ignore every unknown event.** Rejected because a reader cannot infer that an unknown durable fact is informational. Silent omission can resume a session with incorrect model input or plugin state.
+
+**Bump the session format for every new event type.** Rejected because the generated type guard already makes older readers fail safely at the exact unsupported record, while newer readers continue to accept older logs. The format integer remains reserved for changes that alter how known records must be interpreted.
+
+**Register known event names from mounted plugins.** Rejected without a current external consumer because the same build would accept or reject one stored log according to runtime composition. A future registration design must distinguish required plugin state from genuinely optional records and preserve that distinction on disk.
+
+**Use major/minor versions or rewrite on view.** Rejected because upgrade availability is a property of each version step, not a promise encoded by two counters, and opening a session must not destructively rewrite its only artifact. A converter defect must not turn browsing into data loss or make an older runtime lose access merely because a newer one viewed the log.
+
+## Consequences
+
+An older build cannot resume a newer same-version log once that log contains any event type it does not know, even when the new event is informational. This is a deliberate loss of unused forward-degradation behavior in exchange for one event envelope and one failure rule. If a real producer later requires older readers to continue around an optional event, the design must classify the event type once, make `Session.append()` emit the persisted classification automatically, and cover both persistence backends and the wire representation.
+
+First-party JSONL session bytes remain unchanged, including packed rows and `SESSION_FORMAT_VERSION = 0`. Existing first-party JSONL sessions remain readable. SQLite is opt-in and follows the pre-release schema policy: schema 18 has no migration from schema 17, and incompatible databases refuse rather than being rewritten. The [SQLite physical compression decision](../architecture/2026-08-18-sqlite-physical-chunk-row-compression.md) owns that backend's packed-row representation.
+
+The assembled headless refusal test proves that a user sees the unknown type, sequence, newer-writer direction, and raw JSONL path. Core seed tests reject fields outside the current event envelope; persistence contract tests reject every unknown type; SQLite codec and differential tests cover scalar and packed discrimination, suffix reads, repair, and cross-backend logical equality. The generated persistence catalog and known-event module keep the reader's set synchronized with repository-owned declarations.

+# Agent Note: 读取时要求会话事件类型已知
+
+Status: implemented
+
+[English](2026-08-25-fail-closed-session-event-vocabulary.md) | 中文
+
+## 问题
+
+会话读取器不得静默省略自己无法理解的持久事件。未知事件可能改变后续请求重建、策略状态、恢复或其他插件所有的投影，因此 JSON 解析成功不足以证明读取保真。[问题 #1901](https://github.com/deepseek-ai/deepseek-harness/issues/1901) 之前的读取器会放行未知事件类型，而核心折叠会忽略它们，使恢复的会话可能在没有诊断的情况下丢失语义。
+
+最初的拒绝机制将生成的已知事件集合与可选的逐记录 `ignorable: true` 声明结合，该声明原本用于信息性新增事件。没有任何生产写入方使用该声明，`Session.append()` 也没有暴露设置方式。机制落地后新增的事件类型仍然都是读取必需项。但这个未使用字段仍然扩大了权威事件类型、seed 校验、持久化格式、SQLite schema、会话传输、DeepSeek 请求扩展、生成目录、文档与测试。
+
+## 决策
+
+每个会话事件类型都是读取必需项。受支持的 legacy 记录归一化后，`PersistenceCoordinator` 会将每个事件类型与 `KNOWN_SESSION_EVENT_TYPES` 比较；后者是从本仓库声明的所有 `SessionEventMap` 成员生成的集合。任何未知类型都以 `SessionFormatUnsupportedError` 拒绝重建；诊断会列出事件与序号，指明日志可能由更新的写入方生成，并在后端拥有独立原始产物时附上该路径。该守卫仍只在读取侧生效，因为在实时事件已提交后拒绝追加会中断持久化，使会话无法在下次加载时报告不受支持的日志。
+
+`SessionEvent` 没有可选的未知事件跳过字段。JSONL 继续序列化相同的事件对象，因为生产追加路径从未发出该字段，`SESSION_FORMAT_VERSION` 仍为 `0`。SQLite 提供方将被复用的 `ignorable` 列替换为 schema 18 的 `is_packed` 判别值：标量逻辑事件存储 `0`，打包分片行存储 `1`，与物理分片标签同名的事件在协调器应用已知类型守卫之前仍可明确解码。
+
+`SESSION_FORMAT_VERSION` 仍是单个单调整数。当较旧运行时无法完全正确地解释某项结构或语义变更时，写入方必须升版本：会话 header 字段、事件 envelope 字段、核心事件语义或 `SurfaceEventType`/`SurfaceOp` 机制。仅新增事件类型无需升版本，因为较旧读取器会拒绝该确切的未知类型，而不是误读日志。版本相等时正常读取；版本不等时当前以分方向诊断拒绝。n→n+1 升级器链仍推迟到第一个真实 v0→v1 步骤提供可测的输入和输出时建立。未来的查看升级属于内存转换，只有用户继续会话时才持久替换；缺失的步骤会保留源产物以供原始查看。
+
+仓库外的 `SessionEventMap` 成员仍不在生成集合内。它们可在实时进程中运行并持久化，但第一方持久化读取器在重新加载时会拒绝它们，直到真实的外部事件消费方证明需要注册机制。这保留了现有的预发布显式限制，同时避免已知集合依赖运行时组合。
+
+## 考虑过的替代方案
+
+**保留逐记录跳过声明。**不予采用，因为它没有生产使用方，无法通过 `Session.append()` 表达，并且要求每种存储与传输表示都保留一项推测性选择。真实需求应先定义可安全省略的事件类型，再让追加实现统一发出该分类，而不是依赖每个调用点。
+
+**忽略每个未知事件。**不予采用，因为读取器无法推断一项未知持久事实是否仅用于信息。静默省略可能使会话以错误的模型输入或插件状态恢复。
+
+**为每个新事件类型升级会话格式。**不予采用，因为生成的类型守卫已使较旧读取器在确切的不受支持记录处安全失败，而较新读取器仍可接受较旧日志。格式整数仍保留给会改变已知记录解读方式的变更。
+
+**从已挂载插件注册已知事件名称。**在没有当前外部消费方时不予采用，因为同一构建会根据运行时组合接受或拒绝同一份存储日志。未来的注册设计必须区分必需插件状态与真正可选的记录，并将该区分持久保存。
+
+**使用主版本／次版本或在查看时改写。**不予采用，因为升级可用性是每个版本步骤的属性，不是两个计数器编码的承诺；打开会话也不得破坏性地改写其唯一产物。转换器缺陷不得让浏览变成数据丢失，也不得仅因较新运行时查看过日志就使较旧运行时失去访问权。
+
+## 后果
+
+较旧构建在较新的同版本日志包含任何未知事件类型后都无法恢复该日志，即使新事件仅用于信息。这是对未使用的前向降级行为的有意放弃，换取单一事件 envelope 与单一失败规则。如果真实生产方以后需要较旧读取器跳过可选事件并继续会话，设计必须只对事件类型分类一次，让 `Session.append()` 自动发出持久分类，并覆盖两个持久化后端和线上表示。
+
+第一方 JSONL 会话字节保持不变，包括打包行与 `SESSION_FORMAT_VERSION = 0`。现有第一方 JSONL 会话仍可读。SQLite 是可选功能，并遵循预发布 schema 策略：schema 18 不从 schema 17 迁移，不兼容数据库会被拒绝而不是改写。[SQLite 物理压缩决策](../architecture/2026-08-18-sqlite-physical-chunk-row-compression.zh.md)拥有该后端的打包行表示。
+
+组装后的 headless 拒绝测试证明用户会看到未知类型、序号、更新写入方方向与原始 JSONL 路径。核心 seed 测试拒绝当前事件 envelope 以外的字段；持久化约定测试拒绝每个未知类型；SQLite codec 与差分测试覆盖标量与打包判别、后缀读取、修复与跨后端逻辑相等。生成的持久化目录与已知事件模块使读取器集合与仓库所有的声明保持同步。

 ## Format refusal — logs a build cannot faithfully read
 
-A backend refuses a log it cannot faithfully interpret with `SessionFormatUnsupportedError`, distinct from `SessionPersistenceCorruptionError` because nothing is damaged. A header `version` ahead of `SESSION_FORMAT_VERSION` names the direction ("written by a newer harness — upgrade the harness to open it"); one behind it states that this build ships no upgrade path. After legacy-shape normalization, an event type outside this build's generated vocabulary (`KNOWN_SESSION_EVENT_TYPES`, emitted by `gen-persistence-catalog`) refuses the same way unless the event's envelope carries `ignorable: true` — silently skipping an unrecognized required event could change how the rest of the log must be read. The message appends the raw log path when the backend keeps one artifact per session, so the refused text stays reachable. The JSONL backend refuses a foreign version straight from the raw header line, before validating this format version's header shape or decoding any event row — a structurally different future format still reports the upgrade direction, never "corrupt"; SQLite gates whole-file structure through its own `SCHEMA_VERSION` pragma first. Design rationale and the deferred upgrader chain live in the [session-log-version-mechanism note](../../.agents/notes/implemented/architecture/2026-08-10-session-log-version-mechanism.md).

Every statement and fixed pragma comes from packaged `.sql` resources in `resources/sql/`, and runtime values are bound as SQLite parameters, so package code never assembles query text.
 
 Each connection disables SQLite trusted schemas and memory-mapped I/O, verifies the requested journal mode, and pins `synchronous=FULL` so a resolved append remains durable across an OS crash or power loss. On POSIX, the database parent directory and file must belong to the current user, the parent must not be group/world-writable, and the file must grant no group or world permissions; Windows additionally rejects symbolic links and non-regular files, while ACL restriction stays the deployment's job. Path and ownership failures reject plugin initialization; Node's SQLite driver loads lazily on the first persistence operation. Ordinary `create` stays lazy until the first append, while `ensureMaterialized` writes a session metadata row with no event rows.

 - **Packing depends on batch boundaries** — a compatible run split by the write-behind window or an explicit flush stays split across physical rows; this avoids rewriting prior rows at the cost of a timing-dependent packing ratio.
 - **Synchronous SQLite and compression** — Node's SQLite driver and Zstandard calls block the JavaScript thread; the 4 KiB compression threshold bounds per-frame work for small records.
 - **Busy waits block the event loop** — SQLite waits inside synchronous calls; a competing writer can stall the thread for up to the configured `busyTimeoutMs`.

Automating transfer needs: an export format that preserves header lineage (`seedLength`, `parentSession`, `agentPreset`) and revision semantics; an upgrader chain for format and schema versions, the deferred chain from the [session-log-version-mechanism note](../../../.agents/notes/implemented/architecture/2026-08-10-session-log-version-mechanism.md); and a source-side guarantee that the log is readable and balanced before export — `load` already commits cold repair.

 **Compress every payload.** Rejected because small independent Zstandard frames add headers and synchronous CPU work while losing the cross-record dictionary opportunity of a whole-file stream. On the 105-session comparison corpus, a threshold sweep produced 75.01 MB at 4 KiB, versus 93.87 MB at 16 KiB and 60.92 MB at 1 KiB. The writer fixes level 3 rather than inheriting a library default, matching the moderate level used by [Codex cold-rollout compression](https://github.com/openai/codex/blob/main/codex-rs/rollout/src/compression.rs) while retaining independent row access.
 
-The final frozen comparison used 105 sessions, 2,507,860 logical events, 512-event durable batches, three independent builds per backend, and three read passes per build. SQLite used 75.01 MB, wrote in 8.58 s, read complete sessions at 3.95/21.58 ms p50/p95, read 50-event tails at 0.253/0.378 ms, and forked every session in 13.10 s. Zstandard JSONL used 30.65 MB and measured 28.21 s, 4.49/23.36 ms, 10.58/80.90 ms, and 14.48 s. The predecessor scalar SQLite layout used 709.57 MB and measured 10.64 s, 9.02/69.16 ms, 0.189/0.293 ms, and 19.30 s. The packed layout is 89.4% smaller than the predecessor, writes 19.4% faster, improves complete-read p50/p95 by 56.2%/68.8%, and reduces 2,507,860 physical event rows to 65,810. Scalar tail-50 and list micro-latency are lower, but the packed provider remains materially faster than JSONL on those paths and wins the dominant size, write, full-read, and fork costs. The 4 KiB threshold is the accepted balance rather than a strict dominance claim.

This comparison measured schema 17; schema 18 retains the chunk codec and bounds but changes the row discriminator, so the exact size and timing values remain schema-17 evidence until schema 18 is remeasured.
 
 **Store packed payloads under the logical `assistant/chunk` type.** Rejected because payload heuristics make malformed rows ambiguous and couple physical decoding to future logical payload fields. Explicit tags fail loudly.

+The packed layout trades disk space for speed and structure. The available benchmark measures schema 17, the packed predecessor with the same chunk codec but the former row discriminator; schema 18 has not been remeasured. On its corpus — 105 sessions, about 2.5 million events — the SQLite database used 75 MB against 31 MB for the default compressed JSONL logs: roughly 2.5× the on-disk size.
 
 The same measurements show writes finishing about 3× faster, 50-event suffix reads about 40× faster, full-session reads comparable or slightly faster, and about 2.5 million physical rows shrinking to roughly 66 thousand. Expect 2–3× the compressed JSONL footprint depending on session content; the full numbers and method live in the [SQLite physical chunk-row decision](../../../.agents/notes/implemented/architecture/2026-08-18-sqlite-physical-chunk-row-compression.md).

-语料为 105 个会话、2,507,860 个逻辑事件，按 512 个事件一批追加，因此具体比例取决于会话内容、流密度与批次边界。`SQLite（legacy）` 是标量布局——每个逻辑事件一行、不打包——其 709.57 MB 的占用正是打包行的动机。相对 JSONL，schema 17 磁盘占用约为 2.5 倍，但写入快约 3.3 倍，完整会话读取在两个分位上都更快，50 个事件尾部读取快约 40 倍；相对标量布局，它缩小约 89%、写入更快，并把 2,507,860 行缩减到 65,810 行，只有标量尾部读取仍略快（0.189 对 0.253 ms p50）。写入路径或 schema 变化时，请重跑或扩展该基准。
