+# Agent Note: Foreground activation for the Win32 picker via a synthesized Alt press
+
+Status: implemented
+
+English | [中文](2026-09-07-win32-picker-foreground-alt-key.zh.md)
+
+## Problem
+
+The web GUI host picks a workspace directory through the native Win32 folder dialog, which runs in a child process the host spawns (issue #3543). Windows grants the foreground only to the foreground process, to a process it started, or to a process that received recent input; a child of a background server process qualifies for none of these, so the dialog that `Show` opens sits behind every visible window even though it is the child's first window. The first-window activation assumption behind the spawn design ([archived feature note](../../archived/feature/2026-08-02-win32-in-process-folder-dialog.md)) holds only when the spawner chain owns the console foreground, as in a console-launched CLI.
+
+## Decision
+
+`runFolderDialog` calls a new `pressAltForForeground` binding between the `showing` notice and the blocking `Show`. The binding synthesizes one Alt press (`keybd_event` with `VK_MENU`, down then up) on the dialog thread, which makes Windows count this process as the most recent input owner — one of the documented grounds for foreground activation — so the dialog window `Show` creates activates as foreground. The bindings module already loads koffi's `user32`, so the change adds one function fetch and two invocations. The press is unconditional on Windows. When the process already holds foreground rights (a console-launched CLI), the dialog activates anyway and the press is inert; the window focused at that moment still receives the lone Alt and may briefly highlight its menu bar. Environments that suppress injected input (secure desktops, restricted remote sessions, an elevated foreground window) leave the dialog behind other windows, and the package README records that limit.
+
+## Alternatives considered
+
+**Custom URL protocol with a browser click gesture.** Draft PR #3544 granted the foreground by navigating the foreground browser to a registered `dsh-picker://` URL, which makes the shell launch the dialog process as a foreground descendant. The grant is deterministic by design, but the mechanism spans registry and VBS launcher files, a protocol entry point, a picker-result HTTP route with per-boot tokens, and a first-use browser confirmation, and it adds a server route the browser can reach. The synthesized press removes that entire surface.
+
+**AllowSetForegroundWindow from the clicker.** The API must be called by the current foreground process — the browser — and may name only one permitted process; the spawner cannot invoke it on the browser's behalf.
+
+**AttachThreadInput to the focused thread.** Attaching the dialog thread to the focused window's thread also bypasses the foreground restriction and avoids the keystroke side effect, but it is equally undocumented, needs the focused window's thread id at show time, and fails when the focused window belongs to a higher-integrity process; it was not prototyped.
+
+## Consequences
+
+The picker keeps its single spawned-child design and gains foreground behavior in the background-host case at the cost of one koffi call pair. The bindings spec pins the Alt down/up sequence and its position immediately before `Show` over the fake COM world; the logic spec pins the full showing → press → `Show` order. The Windows CI lane still opens and abort-closes a real dialog with the press present but asserts no activation. Validation on a Windows 11 machine with the foreground lock forced to its maximum reproduced the failure without the press (dialog behind other windows) and the foreground dialog with it in five of five repeat runs; Windows 10 is unverified. Synthesized input is consumed asynchronously by the raw input thread, so the activation grant is in principle race-prone; no miss appeared across the repeat runs, and fragile environments stay a documented package limitation rather than a second mechanism, because the browse backend remains the composition-level answer where native picking cannot be trusted.

+# Agent Note: 通过合成的 Alt 按键让 Win32 选择器获得前台激活
+
+Status: implemented
+
+[English](2026-09-07-win32-picker-foreground-alt-key.md) | 中文
+
+## Problem
+
+web GUI 宿主通过原生 Win32 文件夹对话框选择工作区目录，对话框运行在宿主 spawn 的子进程中（issue #3543）。Windows 只把前台授予前台进程、由前台进程启动的进程或最近收到输入的进程；后台服务器进程的子进程三者都不满足，因此 `Show` 打开的对话框即使属于子进程的首个窗口，也会落在所有可见窗口之后。spawn 设计背后的"首窗口即激活"假设（[归档功能记录](../../archived/feature/2026-08-02-win32-in-process-folder-dialog.md)）只在 spawn 链持有控制台前台时成立，例如控制台启动的 CLI。
+
+## Decision
+
+`runFolderDialog` 在 `showing` 通知与阻塞式 `Show` 之间调用新增的 `pressAltForForeground` 绑定。该绑定在对话框线程上合成一次 Alt 按键（`keybd_event` 携带 `VK_MENU`，先按下后抬起），使 Windows 把该进程计为最近的输入所有者——文档记载的允许前台激活的理由之一——于是 `Show` 创建的对话框窗口以前台方式激活。bindings 模块已经加载 koffi 的 `user32`，因此改动只增加一次函数获取与两次调用。该按键在 Windows 上无条件执行。当进程已经持有前台权利（控制台启动的 CLI）时，对话框本来就会激活，按键不起作用；此刻获得焦点的窗口仍会收到这一次单独的 Alt，可能短暂高亮其菜单栏。在合成输入被抑制的环境（安全桌面、受限远程会话、提权前台窗口）中，对话框仍会落在其他窗口后面，包 README 记录了该限制。
+
+## Alternatives considered
+
+**自定义 URL 协议加浏览器点击手势。** 草稿 PR #3544 通过让前台浏览器导航到已注册的 `dsh-picker://` URL 来授予前台，使 shell 把对话框进程作为前台进程的后代启动。该授权按设计具有确定性，但机制横跨注册表与 VBS 启动器文件、协议入口点、携带每次启动令牌的 picker-result HTTP 路由，以及首次使用时的浏览器确认，还增加了一条浏览器可达的服务端路由。合成按键删除了整个这一面。
+
+**由点击方调用 AllowSetForegroundWindow。** 该 API 必须由当前前台进程——浏览器——调用，并且只能点名一个被允许的进程；spawner 无法代替浏览器调用它。
+
+**对聚焦线程 AttachThreadInput。** 把对话框线程附着到焦点窗口所属线程同样能绕过前台限制且没有按键副作用，但同样没有文档契约，需要在显示时取得焦点窗口的线程 id，并在焦点窗口属于更高完整性进程时失败；未做原型验证。
+
+## Consequences
+
+选择器保持单一 spawn 子进程设计，并在后台宿主场景获得前台行为，代价是一次 koffi 调用对。bindings spec 在假 COM 世界上固定了 Alt 按下/抬起序列及其紧邻 `Show` 之前的位置；logic spec 固定完整的 showing → press → `Show` 顺序。Windows CI lane 仍会真实打开并中止关闭一个对话框（按键存在），但不断言激活。在一台把前台锁强制到最大值的 Windows 11 机器上做了验证：不加按键复现失败（对话框在其他窗口后面），加上按键后对话框获得前台，五轮重复全部成功；Windows 10 尚未验证。合成输入由 raw input thread 异步消费，因此激活授权原则上存在竞争窗口；重复运行中未出现错过，脆弱环境仍是记录的包限制而非第二套机制，因为浏览后端仍是原生选择不可信场景在组合层面的答案。

-# Automated review requests
+# Automated pull-request reviews
 
 ## Summary
 
-The [`request-review` workflow](../workflows/request-review.yml) reads the CODEOWNERS-compatible [ownership map](CODEOWNERS) from the trusted default branch. It classifies changed files, requests missing owners for reviewable code, and cancels its outstanding requests when a pull request becomes a draft. The ownership map is outside GitHub's native CODEOWNERS locations, so GitHub does not apply it directly.
+The [`request-review` workflow](../workflows/request-review.yml) requests owners for reviewable code. The [`weighted-approval` workflow](../workflows/weighted-approval.yml) publishes an approval score for branch rules. Both workflows execute policy from the trusted default branch.

+
+## Approval scoring
+
+The weighted approval workflow publishes the `weighted approval` commit status on the pull request head. Branch rules must require this status context. The status succeeds at two approval points, remains pending below two points or while the pull request is a draft, fails while a write-capable reviewer has an effective `CHANGES_REQUESTED` review, and reports an error when policy evaluation fails.
+
+Reviewers whose calculated base repository permission is `write` or `admin` count. The [approval policy](approval-policy.json) gives `@07akioni`, `@imccyu`, `@tianyicui`, `@tianyicui-bot`, `@turtle1999`, and `@turtle2099` two points each; every other write-capable reviewer gets one point. The pull-request author and reviewers without write permission do not count.
+
+Each reviewer contributes only the latest non-comment `APPROVED` or `CHANGES_REQUESTED` decision that GitHub returns. Comment-only and dismissed review records do not replace an effective decision. The workflow does not invalidate an approval by its review commit; the repository's native pull-request rules own stale-review and latest-push requirements.
+
+The workflow runs when a pull request opens, synchronizes, reopens, becomes ready, or becomes a draft, and when a review is submitted, edited, or dismissed. It fetches every review and resolves current repository permission before publishing the status. Permission changes take effect on the next subscribed pull-request or review event.

 ## Approval scoring
 
-The weighted approval workflow publishes the `weighted approval` commit status on the pull request head. Branch rules must require this status context. The status succeeds at two approval points, remains pending below two points or while the pull request is a draft, fails while a write-capable reviewer has an effective `CHANGES_REQUESTED` review, and reports an error when policy evaluation fails.
+The weighted approval workflow publishes the `weighted approval` commit status on the pull request head. Branch rules must require this status with GitHub Actions as its expected source; a context-only requirement can accept a same-named status from another integration. The status succeeds at two approval points, remains pending below two points or while the pull request is a draft, fails while a write-capable reviewer has an effective `CHANGES_REQUESTED` review, and reports an error when policy evaluation fails.
 
 Reviewers whose calculated base repository permission is `write` or `admin` count. The [approval policy](approval-policy.json) gives `@07akioni`, `@imccyu`, `@tianyicui`, `@tianyicui-bot`, `@turtle1999`, and `@turtle2099` two points each; every other write-capable reviewer gets one point. The pull-request author and reviewers without write permission do not count.
 
-Each reviewer contributes only the latest non-comment `APPROVED` or `CHANGES_REQUESTED` decision that GitHub returns. Comment-only and dismissed review records do not replace an effective decision. The workflow does not invalidate an approval by its review commit; the repository's native pull-request rules own stale-review and latest-push requirements.
+Each reviewer contributes only the current `APPROVED` or `CHANGES_REQUESTED` decision that GitHub returns. A `DISMISSED` record clears that reviewer's standing decision, including earlier approvals. Comment-only and pending records do not replace a decision. Reviews from deleted accounts and reviewers without current repository access do not count. The workflow does not invalidate an approval by its review commit; the repository's native pull-request rules own stale-review and latest-push requirements.
 
-The workflow runs when a pull request opens, synchronizes, reopens, becomes ready, or becomes a draft, and when a review is submitted, edited, or dismissed. It fetches every review and resolves current repository permission before publishing the status. Permission changes take effect on the next subscribed pull-request or review event.
+The publisher runs when a pull request opens, synchronizes, reopens, becomes ready, or becomes a draft. Review submissions, edits, and dismissals run the no-permission [`weighted-approval-review-event` workflow](../workflows/weighted-approval-review-event.yml); its validated run title supplies the pull-request number to the default-branch publisher. The publisher validates the current head, fetches every review, and resolves current repository permission before publishing the status. Permission changes take effect on the next subscribed pull-request or review event.

 **Locale dictionaries own all product-authored client UI wording.** Visible text, accessibility names, tooltips, placeholders, empty states, status labels, units, and formatting templates reach presentation through a typed `t` seat or an already-localized prop. A value authored by a user, model, provider, plugin, wire peer, or operating system remains data and renders verbatim; protocol tags, tool names, paths, URLs, JSON/JavaScript literals, and stable internal ids are not translated.
 
+Product-owned catalog descriptions follow the same rule. The client maps an exact built-in provider, model, and description to a locale key; a changed description or an external provider description remains provider data and renders verbatim.

 **Cordis-free primitives require complete localized copy props and own no language fallback.** `MarkdownText`, `JsonTree`, `TerminalBlock`, `DiffBlock`, `ReadBlock`, `SearchBlock`, `WebBlock`, `CodeBlock`, `JsonBlock`, `HoverCard`, and `ConnectionIndicator` receive their chrome from the feature render site. This preserves the primitive package's runtime independence while making omission a type error instead of silently selecting Chinese or English. Shared words live in the `common` namespace; feature-specific phrases stay with the feature that decides their meaning.
 
 **Localized display text is never an identity.** Models and stores retain discriminants, stable ids, and non-display markers. Renderers translate after matching, and request maps carry stable group membership into the trajectory ledger. A client-synthesized error that must survive in a view model uses a stable marker and is translated only when displayed. Language switching therefore changes wording without changing selection, grouping, search identity, or lifecycle state.

 ## Turn Process Folding
 
-Settings → General exposes a persisted `Normal` / `Compact` conversation-display preference in the `ui-chat` namespace; `Compact` is the default. Normal leaves process rows visible and renders no Turn-process control. In Compact mode, the System prompt remains independently visible before the opening User throughout the Turn. Context injection, reasoning, Assistant material, Tool rows, and Retry rows remain expanded while a Turn is open. At `turn/end`, its latest Step becomes the final-answer boundary only when it contains non-blank text, an image, or an unknown visible block—and no Tool-call block; preceding Context injection, reasoning, earlier Assistant material, Tool rows, and Retry rows then collapse by default. The control reports Turn-wide durable counts for non-subagent Tool calls, reply-bearing Assistant messages before the final answer, and subagent delegation calls; zero-valued segments are omitted, the Tool and subagent figures are mutually exclusive, and neither System prompt nor Context injection contributes a count. When all three counts are zero, the process still folds and the control reads `Thought for a while`. A full-width divider below the summary separates it from the answer or expanded process rows. User and steering messages, System prompt, error, max-token, and turn-tail rows stay outside, and a closed Turn with no final answer keeps all process evidence visible. A newly available process control is inserted without changing the relative order of existing rows: opening human input precedes the control and process rows from their first projection, while System prompt remains above that input. While older history remains available through Load earlier, process controls stay absent and no members are hidden; once history is complete, every eligible closed Turn uses the collapsed default immediately. Stable Chat Node Seats keep every renderer mounted, hidden members add no flow spacing, and a closed control sits 8px above its answer only when no independent input intervenes. Completion collapse does not depend on tail-follow position, so a reader above the tail may see the transcript reflow. An automatic collapse that would hide keyboard focus keeps the group open and leaves focus in place; a manual close focuses the process control before hiding its members. The session-scoped store records only manually expanded Turn-and-answer-Step generations; a different answer generation starts collapsed.

 ## Summary
 
-The **Plugin list** tab lets Web users inspect plugins without changing their configuration. It presents agent-preset compositions first and keeps the global inventory collapsed until needed. Cards expose enablement, provenance, runtime status, disabled conditions, and discovery failures; global entries supplied by presets are identified with the enabling presets. Search covers both groups and points to matches in other presets. The tab supports loading, empty, no-match, failure, and retry states without exposing transport details, and it still shows the global inventory when no preset roster is available.

 ### Reading a card
 
-Each collapsed card uses the short module name as its title and a small enablement tag; enabled entries also show a colored root-fiber status dot. Expanding one card reveals the declared entry id, the full module specifier, and the state facts: a preset row names the preset it comes from, its runtime status when the composition is live, and its disable condition when it carries one; a preset-provided global row explains that agent presets provide it per session, names the presets that enable it, and offers a jump into the preset group. Preset names resolve through the shared `presetDisplayText` fold (`dsh-agent-presets/display`) over [`ui-agent-preset`](../ui-agent-preset/README.md)'s dictionaries: shipped presets follow the active locale while user-authored ones keep their own metadata, so an English surface never echoes the preset files' Chinese names. Search filters both groups by module name and entry id.

-Row keys are scope-qualified (`global:`, `preset:<id>:<index>`), so one module appearing in both scopes keeps distinct disclosure state; an entry id is shown as detail only when the row declares one and is never classified by string shape. The preset-provided marking is derived client-side: a global entry carries it when it is disabled there while at least one preset row for the same module specifier is actually enabled, so a module every preset gates off (or declares only conditionally) stays plainly disabled rather than over-claiming provision.

The `mcp__` marker keeps MCP registrations out of the native tools' namespace and gives permission/telemetry rules a stable shape (`mcp__*`, `mcp__github__*`).
 
-1. On connect: drain `client.listTools()` pagination, derive every tool's `publicName`, then register each as a raw `ToolDefinition` via `ctx.tools.register()`. The MCP JSON Schema and description pass through unchanged (no `defineTool` DSL conversion); only the model-facing `name` is replaced.
+1. On connect: drain uncached `tools/list` pagination, derive every tool's `publicName`, then register each as a raw `ToolDefinition` via `ctx.tools.register()`. The MCP JSON Schema and description pass through unchanged (no `defineTool` DSL conversion); only the model-facing `name` is replaced.
 2. Listen for `notifications/tools/list_changed` → re-run the same sync (dispose previous generation, register new). Deterministic names mean unchanged tools keep their names across re-syncs.
 3. The executor closes over `rawName`; the public name is never sent to the server and never parsed to recover the raw name.
 4. No `presentCall`/`presentResult` — UI consumers use the provider-neutral generic-card fallback.
 5. Tools are transparent in the system prompt — no "[via MCP]" annotation beyond the name itself.
 
+Each synchronization rejects a repeated non-empty continuation cursor before requesting another page, retaining the previous tool generation. Empty pages cannot establish progress through tool-name uniqueness, so cursor history also detects cycles spanning several pages ([reported failure](https://github.com/deepseek-ai/deepseek-harness/discussions/3660)). Cursor history belongs to one synchronization: a later update may reuse the same cursors. Focused bridge and lifecycle tests cover cycle rejection, retained callable tools, strict startup failure, and notification recovery. This detects repeated cursors; it does not bound a server that continually returns distinct cursors.
+
 ### Public name normalization
 
 MCP allows tool names up to 128 characters including `.`; the DeepSeek function-name contract allows `[A-Za-z0-9_-]` and at most 64. Public names are normalized deterministically: invalid characters become `_`, and when replacement or truncation changed the name, a 12-hex-char SHA-256 hash of the `(serverName, rawName)` identity is appended so distinct MCP identities can never collapse into the same public name:

 ### 公开名称规范化
 
 MCP 允许工具名最长 128 字符且可包含 `.`；DeepSeek 的函数名约定允许 `[A-Za-z0-9_-]` 且最多 64 字符。公开名称按确定性规则规范化：非法字符替换为 `_`，当替换或截断改变了名称时，追加 `(serverName, rawName)` 标识的 12 位十六进制 SHA-256 hash，确保不同的 MCP 标识永远不会坍缩为同一个公开名称：

 A right-Sidebar tab body, a chat card, or any other slot component often needs live data it knows only by address: the file an agent just wrote, later a chat node or a terminal. Before the resource model each consumer fetched for itself — the text preview owned its own Remote call and refresh loop — so every mount re-read, two components showing one file held two copies, switching tabs unmounted the body and lost its content, and each new kind of content meant a new bespoke hook.
 
-The tab record set the constraint. A tab must survive undo, redo, reload, and hot module replacement without the code that opened it, so the record can hold only serializable data: an address and navigation parameters. The opener therefore cannot hand a body its data, and injection is the wrong tool — injection is a registration-time relation between a domain and a seat, while opening is a runtime event. A component has to find its data from the address alone, through something registered once by whoever owns that kind of data.

 ### Addresses
 
-A resource address is a `dsh-resource://<type>/…` URL. The host is the protocol key — the key of `ResourceProtocolMap` — and the path belongs to the protocol's owner. `RESOURCE_SCHEME = 'dsh-resource'` is the one scheme constant; `protocolOf(address)` parses the string with `new URL`, requires `protocol === 'dsh-resource:'`, and returns the lower-cased host, or `undefined` for a string the parser rejects, another scheme, or an empty host. `dsh-resource` is not one of the URL specification's special schemes, so the parser keeps the host's case and treats the path as opaque; the lower-casing is explicit, and each path segment is percent-encoded by the protocol that defines it. A protocol that needs a scope encodes it in the path: `dsh-resource://file/session/<sessionId>/<path relative to that session's workspace root>`, with `session/<sessionId>` naming the session whose root resolves the file, or `dsh-resource://file/absolute/<absolute path>`, which carries no session and is read through the current one ([grammar](../../../../packages/util/workspace-path/README.md)). Any other scheme — `sidebar://guide` — is a navigation address: it names a tab, not data, and the model answers `none` for it ([tab types and navigation](2026-09-05-sidebar-tab-types-and-navigation.md)).

 ### The hook
 
-`useResource` is declared on `GlobalStandardProps` in `ui-slots`, so every slot component has it whatever its scope, and the plugin provides it through `ctx.slots.provideRoot({ keyedHooks: { resource: address => resources.source(address) } })`, the same root keyed-hook path `useSessions` uses. It is not a session standard prop: a resource carries its own scope in its address, and components outside any session scope read resources too. `useResource<P>(address)` returns the snapshot: `none` when the address's protocol has no provider or the address is not a resource address, `loading` between the stream opening and its first frame, `live` with the latest `ok` value, `failed` with the latest frame's failure beside the last value. `reload()` asks the provider for a fresh frame and is a no-op when the protocol has no provider or no `reload`.

 ### Frames
 
-A provider yields `RemoteResult` frames: the current state first, one frame per later change. An `ok` frame makes the resource `live`, replaces the value, and clears the failure; an `ok: false` frame makes it `failed`, records the failure, and keeps the last value. Failure is data, not an exception: the Remote face already folds failures into `ok: false` and never rejects, providers pass those frames on, and the model neither catches nor wraps — a throw inside a provider's stream is a programming error left to surface. A stream that ends on its own keeps its last state; frames a provider yields after the release that aborted it are dropped and the iterator is returned. Streams carry metadata, not payload: the `file` value is `{ absolutePath, version, bytes?, changed }`, and a consumer reads content itself, by page, through the [Workspace Files service](2026-09-05-workspace-files-service.md).

 ### Lifecycle
 
-One record exists per address. Its holders are the hook's subscribers plus pins; the first holder opens the provider's stream under an `AbortController`, later holders share it and read the latest value at once, and the last release aborts the stream and resets the snapshot to idle — `loading` while a provider is registered, `none` otherwise. A provider that arrives while an address is already held opens that address's stream; one that leaves aborts it and the address reads `none`. Records are kept for the page lifetime so `source(address)` stays reference-stable across React's render-then-subscribe window and a StrictMode remount, where a recreated record would resubscribe and restart the stream on every render.

 The right Sidebar's Tab domain pins every open tab record's address for the record's life, so switching tabs unmounts a body without closing its stream and switching back reads the latest value; a record restored by undo is a new pin, and a resource the model already let go is read again ([tab types and navigation](2026-09-05-sidebar-tab-types-and-navigation.md)). `openResource(address)` accepts resource addresses only; pages such as the guide and the file tree are opened by kind and never enter the resource model.

 ## Consequences
 
-Any slot component reads live data by address and nothing else, so an opener passes data only and a body reconstructs itself from its record after undo, reload, or hot replacement. Two components showing one address share one stream, and a pinned address survives its body's unmount. A protocol's transport lives in exactly one provider, and adding a protocol is one declaration-merged type plus one registration.

A protocol's transport lives in exactly one provider, and adding a protocol is one declaration-merged type plus one registration.
 
 The costs are recorded here so they are not rediscovered. Records are never reclaimed: memory grows with the number of distinct addresses ever read, not with reads. Abort compliance rests with the provider; the model drops what a released stream still yields but cannot stop a provider that ignores the signal before its next frame. The failure type is the Remote face's `RemoteFailure`, so a provider whose source is not a Remote call has to mint one. A navigation address or a malformed string reads as `none` rather than an error, which keeps mixed address lists cheap to render but gives a misspelled protocol no diagnostic beyond the missing value.
 
 ## Testing
 
-`packages/client/resources/tests/resources.client.spec.ts` drives the registry with scripted feeds: protocol ownership and disposal, `none` for a protocol without a provider and for a navigation address, a provider arriving after a held address and leaving while it is held, registrations dropped with their fiber, open-on-first-holder and close-on-last, one source per address, pins including an already-aborted signal, a remount reading the latest value without reopening, reopening as a fresh stream, frames after abort dropped with the iterator returned, a stream ending on its own, failure frames beside the last value, and `reload` forwarding. `tests/apply.client.spec.ts` mounts the plugin in `SlotTestRuntime` and checks, through a root-scope probe component, that `useResource` reaches props, that rendering it opens the provider's stream, and that disposing the plugin withdraws both the service and the hook.

 - **`stat`** returns `WorkspaceFileStat { absolutePath, version, bytes? }`: the file's identity, its opaque freshness token, and its size when the backend reports one. It accepts a regular file only.
 - **`read`** returns one window of lines, `WorkspaceFileText = WorkspaceFileStat & { offset, text, lines, eof }`; `lines` counts the page's lines, so a page holding one empty line (`text: ''`, `lines: 1`) and a page past the end (`lines: 0`) read differently. `range.offset` is the 1-based first line and defaults to 1; `range.limit` is the largest number of lines and defaults to `maxLines`, which it may not exceed. Lines end at `\n` and a final `\n` terminates the last line rather than opening an empty one; `text` joins the page's lines with `\n` and carries no terminator; `eof` is true when the page includes the last line, and an offset past the end returns an empty page with `eof` true. The pager walks `streamText`, counts the lines before the window without keeping them, admits each in-window segment against `maxBytes` before buffering it, and returns at the first character past the window, so a file of any size costs one page of memory. The `version` and `bytes` on a page are the stat's, taken before the stream.
 - **`readBytes`** returns one window of raw bytes, `WorkspaceFileBytes = WorkspaceFileStat & { offset, data, eof }`. `range.offset` is the 0-based first byte and defaults to 0; `range.length` is the largest byte count and defaults to `maxBytes`, which it may not exceed. `data` is base64, shorter than `length` where the file ends and empty at or past it; `eof` is true when the window includes the last byte. Nothing is decoded and nothing is refused as binary. `read` pages by lines and never by bytes; a byte window is `readBytes`.
+- **`readAll` and `readRelated`** return complete `WorkspaceFileBytes` under `maxFileBytes`. `readRelated` resolves a relative filesystem path from the base file's directory; the Host checks both files under the same workspace rules. [Document Preview](2026-09-08-document-preview-operations.md) owns their loading and address semantics.
 - **`list`** returns `WorkspaceDirectoryListing { path, entries, truncated }`: the listed directory as a workspace path relative to the root (empty for the root), its direct children in the backend's stable name order as `{ name, type, size? }`, and whether `maxEntries` cut the list. `type` is `file`, `directory`, or `other`; a symlink child reports the type of what it points to and a dangling one is `other`, while opening such a child still fails the link gate below. Dotfiles are listed; nothing is filtered.
 - **`changes`** yields `WorkspaceFileWatchFrame`: `{ kind: 'ready' }` after the observation queue is registered and the workspace root resolves, followed by `{ kind: 'change', change }`. The `WorkspaceFileChange` payload is `{ absolutePath, version }` for a present file or `{ absolutePath, absent: true }` for one observed gone. Its source is `fs/observed` inside the workspace root, never an OS watcher. Observations after the first pull are queued, including during root resolution; cancellation or plugin disposal ends the generation.
 
 ### Paths on the wire
 
-Two path vocabularies leave the service, and each method uses exactly one. `read`, `readBytes`, `stat`, and `changes` name a file by `absolutePath`: its absolute path in the filesystem's execution world, symlinks resolved (`ctx.fs.processPath(target)`), so the Client provider matches a change frame to an open address by absolute path: the Client sends the address's path unchanged to the Host and binds the follower only to a successful `stat.absolutePath`, without reading a Session summary's cwd. `list` speaks workspace paths — the same syntax its `path` argument accepts, absolute or relative to the root — because its consumer is a tree rooted there. The field is called `absolutePath` and not `url` because it is not a resource address; the address grammar belongs to `dsh-util-workspace-path` and is described with the resource model. Input paths to `read`, `readBytes`, `stat`, and `list` are absolute or relative to the session's workspace root, never to the backend's own cwd.

 `version` is an opaque string a consumer compares for equality and never parses: the local backend derives it from device, inode, size, and nanosecond mtime and ctime, so a rewrite that leaves the content identical still changes it. `offset` means a line on `read` and a byte on `readBytes`; the two units never mix, and `eof` on either means the window reached the file's end.
 
 ### The four gates
 
-Every `read`, `readBytes`, `stat`, and `list` passes four gates in order, and the constraints are the service's own because the filesystem does not confine reads. The path is inspected before containment is decided, so a caller learns whether an outside path exists and what kind it is before `outside-workspace` refuses it; that is accepted because the caller is the Session's own owner, who can already read the Host through the Agent.

 1. **The path itself.** `lstat` inspects the path before anything follows it: a missing path is `not-found`, and a symlink — wherever it points, including back inside the workspace — is `not-regular-file` (kind `symlink`) for the file methods and `not-directory` for `list`. An empty path is a `gateway/bad-request`.
 2. **Containment.** The path resolves to a target and `ctx.fs.contains(root, target)` decides, where `root` is `sandboxPolicy.resolve({ session }).workspaceRoot` resolved the same way (the session's cwd, falling back to the policy's configured root). A `..` traversal or an absolute path outside the root is `outside-workspace`. A string-prefix comparison is never used: `resolve` realpaths, so a prefix test cannot see a link that leaves the root.
-3. **The caps.** A page or window above `maxBytes`, or a `read` asking for more than `maxLines`, is refused, never shortened, because a silently cut page reads as the whole page; a listing above `maxEntries` is cut and says so.

 4. **Text.** For `read` only: content that is not UTF-8 up to the end of the page, a NUL byte in the backend's 8 KiB opening sample, or a NUL byte anywhere in the page is `not-text`; bytes past the page are not inspected.
 
 After the gates the file methods `stat` the target once more, because the file may have gone or changed kind between the inspection and the read: a vanished file is `not-found` and a replaced one `not-regular-file` with the new kind. The gate order has one visible consequence: an entry outside the root whose type already disqualifies it reports its kind, not its position.

+- **The address names the file; its scope selects the Session.** A `session` address's relative or absolute path reaches the Host unchanged for resolution and containment against that Session's workspace root; Client cwd is not a prerequisite.

 - **One `changes` subscription per Session.** The first follower opens `remote.$stream`, the last release disposes it, and successor streams and plugin teardown await pending closes. The Client starts its first `stat` only after accepting Host `ready`; sending a local WebSocket request is not Host acknowledgement. A follower registers by address, queues changes before its path is known, then filters queued and live frames by the successful stat's `absolutePath`, normalizing backslashes to slashes. Any Session write can trigger a re-stat before the first successful binding. Gateway supervision reconnects carrier loss; Host end or terminal failure ends followers and retains their last metadata until reopened.
 - **Navigation parameters.** `SidebarRightResourceParamsMap.file` is `WorkspaceFileParams { line?: number }`, a 1-based line to reveal. A line travels as a navigation parameter and not as part of the address, because the file is one piece of content whether it opens at the top or at line 400.

 ## Consequences
 
 - Workspace file access belongs to the Host/Client faces of `api/workspace-files`; the Session Controller carries neither implementation, and compiler and runtime entries stay separate.
-- A file of any size opens: text by line page, anything by byte window, each costing one page or window of memory on the Host and never a whole file; the cost is that a consumer assembles pages itself and that a single line above `maxBytes` has no page at all, because pages are cut by lines.
+- A file of any size opens: text by line page, anything by byte window, each costing one page or window of memory on the Host; complete reads instead enforce `maxFileBytes`; the cost is that a consumer assembles pages itself and that a single line above `maxBytes` has no page at all, because pages are cut by lines.
 - Every filesystem provider now offers a windowed raw read. `fs-e2b` pays for it by transferring the skipped prefix, since its SDK cannot seek; `fs-local` seeks.
-- Paths on the wire are canonical: `absolutePath` and change frames spell a file with symlinks resolved. An address built from another spelling of the same file — a workspace root reached through a symlink — opens and stats it, but its change frames never match, so `changed` stays false until a reload.
+- Paths on the wire are canonical: `absolutePath` and change frames spell a file with symlinks resolved. A follower binds to successful `stat.absolutePath`, so another spelling of the same file — a workspace root reached through a symlink — uses that canonical change key.
 - Change frames report the agent's own operations only. A file edited by the user's editor, a shell, or a subprocess raises no frame; an agent merely reading a file that something else changed does raise one, because the read observes a new version.
 - The gate order reports kind before position, a page's `version` may be one write behind its content, and a stalled `changes` consumer grows Host memory, because a generation's queue is unbounded; each is a known trade-off recorded in the package README.
 - The `file` resource pushes change, not content, so a preview learns a file moved on without a payload and reads the pages it wants; a failed open keeps following the address, so the agent creating the file brings the tab live without user action.
-- `readBytes` has no shipped consumer yet: it is the wire form the image and binary previews build on.
+- `readBytes` has no shipped consumer yet; Document Preview uses `readAll` for complete-file formats.
 
 ## Testing
 
-Host specs in `packages/api/workspace-files/tests` exercise the paged read (whole file, nested path, empty file, multi-byte UTF-8, the line window's edges, defaults and refused limits, carriage returns kept), the byte window (defaults, a middle window with more following, tail windows exact and short, past-end and empty files, NUL and invalid UTF-8 round-tripping through base64, version parity with `stat`, the cap as `too-large`, bad ranges, a window of a file far above the cap, and `eof` inferred without a size), `stat`, `list` with truncation, symlink children, and `not-directory`, the `changes` stream driven by `fs/observed` and filtered by root, and every gate and code against a real local backend, because a fake filesystem would let a prefix test pass the symlink case the gate exists to catch. Client specs in `packages/api/workspace-files/tests` cover the provider's frames (opening stat, failure frames, writes without content, disappearance, reload, recovery, abort), the change feed (one stream per session, fan-out by normalized path, queued frames, ending on signal or Host close), the unsupported-address cases, and registration and disposal with the fiber. `fs/fs`, `fs-local`, and `fs-e2b` specs pin `readByteRange`'s range semantics — a middle window, a tail shorter than asked, past-end and zero-length windows, errors, aborts, and the e2b cancel — and `dsh-util-workspace-path` specs pin the file-address grammar. The connection fixture serves `stat`, paged `read`, `list`, and an opt-in `changes` frame for the web e2e suite.

 ## Deferred
 
-- A web e2e chain through the Sidebar: open a file, have the agent write it, see `changed`, reload.
-- Aliasing a follower under the Host's canonical spelling once the first `stat` reveals it, so a symlinked workspace root still receives change frames.
 - A bound on a `changes` generation's queue.
 - The shipped consumer of `readBytes` (image and binary previews) and any write, search, or media route; the service is read-only.
 - Scopes other than `session` in the file address; the grammar leaves room, the provider serves one.
-- Reload delivery per record: today `reload` re-stats every follower of the file's absolute path in the session, so two records naming one file — a `session` and an `absolute` address, or two readers with different addresses — clear each other's `changed` flag.

 过关之后文件方法再对目标 `stat` 一次，因为在检查与读取之间文件可能已消失或换了种类：消失者为 `not-found`，被替换者为带新种类的 `not-regular-file`。关的顺序有一个可见后果：根外条目若类型本身已不合格，报告的是其种类而不是其位置。

+# Agent Note: Document preview and file addresses
+
+Status: implemented
+
+English | [中文](2026-09-08-document-preview-operations.zh.md)
+
+## Problem
+
+File viewers need different loading policies and may offer several implementations for one extension. A change stream cannot also express an on-demand read without mixing live data with callable capabilities. HTML dependencies additionally need the Host's filesystem authorization and path resolution, not the browser's current directory.
+
+## Decision
+
+Document Preview separates resource observation from content reads. The [resource model](2026-09-05-client-resource-model.md) shares observations by address alone: `source(address)`, `pin(address, signal)`, and provider `open(address, { signal })` carry no consuming Session. Providers return `AsyncIterable<RemoteResult<ResourceProtocolMap[P]>>`; `useResource` exposes only `{ status, value, failure }`. Holds start and stop observation, not the underlying file or Session. Content reads use ordinary injected Preview callbacks.
+
+[Workspace Files](../../../../packages/api/workspace-files/README.md) retains Host line reads, byte windows, bounded complete reads, and bounded reads relative to another file's directory. Its Client `file` provider observes only `stat` and `changes`, with `ResourceProtocolMap.file` directly naming `WorkspaceFileStat`. The Host continues to resolve and confine every path under the [file-service decision](2026-09-05-workspace-files-service.md).
+
+Readable files use `dsh-resource://file/session/<sessionId>/<path>`. The path may be workspace-relative or absolute; an encoded absolute path retains its leading slash. `fileAddressFor` always emits this Session-address form. The provider and Preview RPC take the Session only from that address, never from the current selection, first holder, or owning tab. A Session-less `absolute` URI cannot be read; the provider reports `workspace-file/unknown-workspace`. Session authorization is a file-protocol rule, not an additional Resource identity.
+
+[Document Preview](../../../../packages/client/ui-sidebar-textpreview/README.md) owns format selection and loading policy. Metadata registers with `ctx.documentPreviews`; components register separately into the keyed `sidebar.right.tab.document` Slot. Extension registrations precede builtins, then longer suffixes and registration order decide. The toolbar lists matching alternatives and remembers a manual choice per tab; plain text is the fallback. The child receives accumulated text or complete native bytes, the original resource address, and the standard `useResource` and `useTabInfo` hooks. Preview calls existing `read`, `readAll`, and `readRelated` through ordinary injection and decodes bytes in its own `rpc.ts`. Refresh remains per tab, with no resource reload, shared `changed` acknowledgement, extra resource wrapper, or content Session.
+
+Markdown and code reuse the incremental primitives with cumulative paged text. HTML and PDF read complete `Uint8Array<ArrayBuffer>` data; Host transport remains base64. Published buffers are borrowed read-only and never persist into layout or Session JSON. PDF.js runs in an owned Worker with version-matched bundled font and decoder data, and copies input before transfer to preserve Preview's retained buffer. HTML runs in a Blob iframe with `sandbox="allow-scripts"`, without same-origin, popup, form, download, or top-navigation privileges. The browser retains its normal external-network rules. Bounded static local JS/CSS reads stay in the parent; the opaque frame creates its own asset Blobs, because it cannot load parent-origin Blobs. Replacing the document replaces the browsing context and revokes its root Blob.
+
+## Alternatives considered
+
+**Methods attached to an Iterator or its values.** This conflates observation with commands and repeats capability identity in data frames. Frames carry data and failures; explicit Preview RPC callbacks perform reads.
+
+**A core public-projection factory, or the same assembly inside `open`.** Separate stream values, operations bundles, and public interfaces add assembly without another current consumer that needs it. Preview's shared RPC adapter already keeps Session decoding and base64 out of renderers. Resource offers no provider-agnostic command interface or opening-bound command lifetime; adding either needs consumer evidence beyond file preview.
+
+**UI Session as extra Resource identity, or authorization from the first holder or current selection.** A retained tab can belong to a different Session from the selected one, and the UI location does not identify the addressed file. Encoding the required Session in the file address preserves Host authorization while letting all readers of one address share observation.
+
+**File-reading methods on every resource.** Chat and terminal resources have independent data and operation semantics; only observation registration and lifetime are common.
+
+**A preview resource wrapper, content Session, or second resource Hook.** These duplicate addressing, cancellation, subscriptions, and ownership already provided by Resource and Workspace Files. Loading policy belongs to the preview owner.
+
+**A local server, virtual host, or `file:` iframe.** These require extra hosting or filesystem authority. The preview is for static generated pages, not a complete application runtime; modules, dynamic filesystem requests, and arbitrary nested asset graphs are outside its support.
+
+## Consequences
+
+Renderers can be replaced without changing the tab or file protocol. Full-file formats pay bounded whole-file memory and PDF adds bundled Worker/font/decoder bytes. Format selection and view state are page-local, not durable Session data. Preview owns RPC cancellation and native buffers independently of metadata observation. A tab retains its read version and the observation version captured at read start; refreshing it neither discards another tab's content nor clears its change notice. File reads remain non-transactional, and opaque versions are compared for equality, not ordering. The [recorded browser scenario](../../../../apps/web/tests/document-preview.e2e.ts) exercises the shared toolbar, incremental text, isolated HTML dependencies, and PDF Worker rendering with retained page state.

+# Agent Note: 文档预览与文件地址
+
+Status: implemented
+
+[English](2026-09-08-document-preview-operations.md) | 中文
+
+## 问题
+
+文件预览器需要不同的加载策略，同一扩展名也可能对应多种实现。变更流无法同时表达按需读取而又不把实时数据与可调用能力混在一起。HTML 依赖还需要 Host 的文件系统授权和路径解析，而非浏览器的当前目录。
+
+## 决策
+
+Document Preview 将资源观察与内容读取分开。[资源模型](2026-09-05-client-resource-model.zh.md)只按地址共享观察：`source(address)`、`pin(address, signal)` 和提供方的 `open(address, { signal })` 均不携带消费 Session。提供方返回 `AsyncIterable<RemoteResult<ResourceProtocolMap[P]>>`；`useResource` 只暴露 `{ status, value, failure }`。持有只控制观察的启停，不控制底层文件或 Session 的生灭。内容通过普通注入的 Preview 回调读取。
+
+[Workspace Files](../../../../packages/api/workspace-files/README.zh.md) 保留 Host 的行读取、字节窗口、有上限的全文读取和相对另一文件目录的有界读取。Client `file` 提供方只观察 `stat` 与 `changes`，`ResourceProtocolMap.file` 直接为 `WorkspaceFileStat`。Host 继续按[文件服务决议](2026-09-05-workspace-files-service.zh.md)解析并限制每条路径。
+
+可读取的文件使用 `dsh-resource://file/session/<sessionId>/<path>`。路径可以相对工作区，也可以是绝对路径；编码后的绝对路径保留前导斜杠。`fileAddressFor` 始终生成这种 Session 地址。提供方与 Preview RPC 只从该地址取 Session，不取当前选择、首个持有者或 tab 所属 Session。不带 Session 的 `absolute` URI 无法读取；提供方报告 `workspace-file/unknown-workspace`。Session 授权是文件协议规则，不是额外的 Resource 身份。
+
+[Document Preview](../../../../packages/client/ui-sidebar-textpreview/README.zh.md) 负责格式选择和加载策略。元数据通过 `ctx.documentPreviews` 注册；组件单独注册到 keyed `sidebar.right.tab.document` Slot。扩展注册优先于内置注册，其次比较后缀长度和注册顺序。工具栏列出匹配候选，按 tab 记住手动选择；纯文本是兜底。子组件收到累积文本或完整原生字节、原始资源地址，以及标准 `useResource` 和 `useTabInfo` 钩子。Preview 经普通注入调用既有 `read`、`readAll` 与 `readRelated`，在自己的 `rpc.ts` 解码字节。刷新仍按 tab 独立进行，不引入资源 reload、共享 `changed` 确认、额外资源包装层或内容 Session。
+
+Markdown 和代码通过累积的分页文本复用增量渲染原语。HTML 和 PDF 读取完整 `Uint8Array<ArrayBuffer>` 数据；Host 传输保持 base64。发布后的缓冲区只读借用，绝不持久化进布局或 Session JSON。PDF.js 在自有 Worker 中运行，字体和解码数据以相同版本随包发布，转移输入前先复制，以保留 Preview 的缓冲区。HTML 在 Blob iframe 中运行，设置 `sandbox="allow-scripts"`，不授予同源、弹窗、表单、下载或顶层导航权限。浏览器保持正常的外部网络规则。有上限的静态本地 JS/CSS 读取由父页面负责；不透明源 iframe 创建自己的资源 Blob，因为它不能加载父源创建的 Blob。替换文档会替换浏览上下文，并撤销其根 Blob。
+
+## 考虑过的替代方案
+
+**把方法挂到 Iterator 或其值上。** 这会混淆观察与命令，并在数据帧中重复能力身份。帧携带数据和失败；显式 Preview RPC 回调负责读取。
+
+**核心公开投影工厂，或在 `open` 内做同样的组装。** 分开的流值、operations 组合与公开接口增加了组装步骤，没有另一个当前消费方需要它。Preview 的共享 RPC 适配已让渲染器无需解码 Session 和 base64。Resource 不提供与提供方无关的命令接口，也不提供绑定于打开实例的命令生命周期；增加任一种都需要文件预览之外的消费方证据。
+
+**把 UI Session 作为额外 Resource 身份，或由首个持有者、当前选择决定授权。** 保留的 tab 可以属于不同于当前选择的 Session，UI 所在位置也不能标识地址指向的文件。将所需 Session 编入文件地址，既保留 Host 授权，也让同地址的所有读者共享观察。
+
+**让所有资源提供文件读取方法。** Chat 与终端资源的数据和操作语义各自独立，只有观察的注册和生命周期是共用机制。
+
+**预览资源包装层、内容 Session 或第二个资源 Hook。** 这些方案重复了 Resource 和 Workspace Files 已提供的寻址、取消、订阅和归属。加载策略属于预览所有者。
+
+**本地服务器、虚拟主机或 `file:` iframe。** 这些方案需要额外托管或文件系统权限。预览面向静态生成页面，而非完整应用运行时；模块、动态文件系统请求和任意嵌套资源图不在支持范围内。
+
+## 影响
+
+替换渲染器不需要改变 Tab 或文件协议。全文格式承担有上限的整文件内存成本，PDF 增加随包发布的 Worker、字体和解码器字节。格式选择和查看状态仅属于当前页面，不是持久 Session 数据。Preview 独立于元数据观察，拥有 RPC 取消和原生缓冲区。tab 保留读取版本及读取开始时捕获的观察版本；刷新它既不丢弃其他 tab 的内容，也不清除其变更提示。文件读取仍非事务，不透明版本只比较相等性、不排序。[录制的浏览器场景](../../../../apps/web/tests/document-preview.e2e.ts) 覆盖共用工具栏、增量文本、隔离的 HTML 依赖，以及保留页码状态的 PDF Worker 渲染。

 ### State
 
+[Default pages and close protection](2026-09-08-sidebar-default-pages.md) supersedes explicit last-tab closing and default-guide reseeding here; moving tabs still settles emptied panes.
+
 `ui-sidebar-right` keeps one `SurfaceState` per session id — the layout, its history, and the mint counter — in a store declared at the seat registration. Every action mints the ids its intent needs, asks a kit planner for the operations, runs the settle planner over the result, and records the whole intent as one history entry before assigning the session's surface back; no action edits a layout in place. The settle step is the product's rule: a docked pane whose last tab is closed, moved out, or floated is merged away, and when only the root pane remains and it is empty, the guide tab is reseeded — there is always at least one tab and never an empty pane, so no pane-closing gesture exists. State is memory-only: a reload returns every session to the collapsed default, and switching sessions keeps each surface where it was. Layout is presentation state and never enters the session log.

 ### The guide
 
+[Default pages and close protection](2026-09-08-sidebar-default-pages.md) supersedes this section's default-guide selection; guide registration, replacement and uniqueness remain unchanged.
+
 The guide is what a pane shows before it holds content. Its registration is `{ id: '@deepseek-ai/dsh-client-ui-sidebar-right/guide', kind: 'guide', priority: 'builtin', title }` with no `patterns`: a guide views nothing, so it is opened by kind through `openTab` and recorded under the page address `sidebar://guide`, which is the registry's bookkeeping and never composed by a caller. The tab's title is `开始` / `Start`, captured into the layout record when the pane is seeded, so a later language change relabels the type and not tabs already open.
 
 The body is a centred column — a lead line (`侧栏用来放你想一直看着的东西。` / `The sidebar holds what you want to keep looking at.`), one line of copy (`会话里的文件和产物会开在这一栏，也可以从下面的入口打开。` / `Files and artifacts from the conversation open in this column; the entries below open more.`), and a grid of entry boxes at most 480px wide, each box at least 160px, filling as many columns as fit. The boxes are projected from every registered type's `guide[]` in `order`, through the registry's observable `guide()` list, so a type registering later appears without the guide knowing it. A box shows the contributing type's glyph, title, and description, and picking it calls `tabActions.openTab(entry.kind, { replaceTab: true })`: the picked type opens in the guide's own tab, and the guide is gone. The guide is a doorway, not a page that stays open beside what it opened.

 ### 引导页
 
+[默认页与关闭保护](2026-09-08-sidebar-default-pages.zh.md)取代本节的默认引导选择；引导页注册、替换和唯一性保持不变。
+
 引导页是 pane 承载内容之前显示的东西。它的注册定义是 `{ id: '@deepseek-ai/dsh-client-ui-sidebar-right/guide', kind: 'guide', priority: 'builtin', title }`，没有 `patterns`：引导页不查看任何东西，所以经 `openTab` 按 kind 打开，并记在页地址 `sidebar://guide` 之下——那是注册表自己的记账，调用方从不拼它。tab 标题是 `开始` / `Start`，在 pane 播种时捕获进布局记录，于是之后切换语言只重标类型，不改已开着的 tab。
 
 体是一根居中的列——一句引导语（`侧栏用来放你想一直看着的东西。` / `The sidebar holds what you want to keep looking at.`）、一行文案（`会话里的文件和产物会开在这一栏，也可以从下面的入口打开。` / `Files and artifacts from the conversation open in this column; the entries below open more.`），以及一组最宽 480px 的入口框栅格，每框至少 160px，能放几列放几列。入口框按 `order` 从每个已注册类型的 `guide[]` 投影而来，经注册表可观察的 `guide()` 列表，因此后注册的类型不用引导页知道就能出现。一个框显示贡献类型的图标、标题与说明；点选它调用 `tabActions.openTab(entry.kind, { replaceTab: true })`：被选的类型在引导页自己的 tab 里打开，引导页随之消失。引导页是一扇门，不是留在被打开者旁边的一页。

+# Agent Note: Sidebar default pages and close protection
+
+Status: implemented
+
+English | [中文](2026-09-08-sidebar-default-pages.zh.md)
+
+## Problem
+
+A guide with one registered entry adds a click without offering a choice. Hiding only the last tab's close button would let an added guide make the default file browser closable again.
+
+## Decision
+
+The Sidebar selects each default page from the registered guide-entry list. Exactly one entry opens that entry's page; zero or multiple entries open the guide. Resource viewers without guide entries do not affect this count. Explicitly adding a guide always opens a guide, and each pane holds at most one.
+
+A single-entry default is protected from explicit close for its record lifetime. Every pane's final tab is also protected; other tabs can close. The Sidebar stores protected record IDs and shares one close predicate between its store actions and docking controls. The generic docking kit accepts a presentation callback and has no file-browser or guide policy. Moving tabs still settles empty panes, and layout state remains memory-only.
+
+This replaces default-guide selection in [the shipped types](2026-09-05-sidebar-text-preview-and-file-tree.md) and explicit last-tab closing in [docking infrastructure](2026-09-04-right-sidebar-docking-infrastructure.md). Their registration, content-state, engine and layout ownership decisions remain active.
+
+## Alternatives considered
+
+**Count all registered tab types or currently open tabs.** Neither counts choices available on the guide; resource viewers need not contribute an entry.
+
+**Protect only the final tab.** Adding a guide would expose a close control on the single-entry default, violating its retained-entry behavior.
+
+## Consequences
+
+One-entry compositions open directly into their registered page without hardcoding Files. Guide selection can still replace its own tab, while ordinary close cannot empty a pane. Store and component tests cover registration counts and close protection; the assembled browser scenarios cover default Files, explicit guide creation, and returning to Files after closing the guide.

+# Agent Note: Sidebar 默认页与关闭保护
+
+Status: implemented
+
+[English](2026-09-08-sidebar-default-pages.md) | 中文
+
+## 问题
+
+只有一个注册入口的引导页增加一次点击，却不提供选择。若只隐藏最后一个 tab 的关闭按钮，新增引导页后，默认文件浏览页又会变得可关闭。
+
+## 决策
+
+Sidebar 从已注册的引导入口列表选择每个默认页。恰好一个入口时打开对应页面；没有入口或有多个入口时打开引导页。没有引导入口的资源查看器不影响计数。显式添加引导页始终打开引导，每个格最多持有一个。
+
+单入口默认页在记录生命周期内受到显式关闭保护。每个格的最后一个 tab 也受保护；其他 tab 可以关闭。Sidebar 保存受保护的记录 ID，store 动作与停靠控件共享一个关闭判定。通用停靠套件接收呈现回调，不拥有文件浏览器或引导页策略。移动 tab 仍会处理空格，布局状态仅存于内存。
+
+本决策取代[随包类型](2026-09-05-sidebar-text-preview-and-file-tree.zh.md)中的默认引导选择，以及[停靠基础设施](2026-09-04-right-sidebar-docking-infrastructure.zh.md)中的显式关闭最后一个 tab。它们的注册、内容状态、引擎与布局所有权决策继续有效。
+
+## 考虑过的替代方案
+
+**统计所有已注册 tab 类型或已打开的 tab。** 两者都不代表引导页提供的选择；资源查看器不一定贡献入口。
+
+**只保护最后一个 tab。** 新增引导页后，单入口默认页会出现关闭控件，违反保留该入口的行为要求。
+
+## 后果
+
+单入口组合直接打开已注册页面，不写死 Files。引导页选择仍可替换自身 tab，普通关闭则不能清空一个格。store 与组件测试覆盖注册数量和关闭保护；组装后的浏览器场景覆盖默认 Files、显式新增引导及关闭引导后返回 Files。

 ## Addresses
 
-A resource address is a `dsh-resource://<type>/…` URL. The host names the protocol and must be a key of `ResourceProtocolMap`; the path is the protocol's own, and its owner percent-encodes each segment. A protocol that needs a scope puts it in the path: the `file` protocol's addresses read `dsh-resource://file/session/<sessionId>/<path relative to that session's workspace root>` or `dsh-resource://file/absolute/<absolute path without its leading />`, built with `fileAddressFor(sessionId, cwd, path)` and read back with `parseFileAddress(address)` from [`dsh-util-workspace-path`](../../packages/util/workspace-path/README.md). The model itself reads only the scheme and the host: `protocolOf(address)` returns the lower-cased host of a `dsh-resource://` URL and `undefined` for anything else. Addresses under any other scheme — the Sidebar's `sidebar://guide` — name no resource and read as `none`.
+A resource address is a `dsh-resource://<type>/…` URL. The host names the protocol and must be a key of `ResourceProtocolMap`; the path is the protocol's own, and its owner percent-encodes each segment. A protocol that needs a scope puts it in the path: the `file` protocol's addresses read `dsh-resource://file/session/<sessionId>/<path>`, where path is workspace-relative or absolute with its leading slashes preserved, built with `fileAddressFor(sessionId, cwd, path)` and read back with `parseFileAddress(address)` from [`dsh-util-workspace-path`](../../packages/util/workspace-path/README.md).

+| `dsh-resource://file/absolute/home/me/notes.md` | `file` | parseable but fails with `workspace-file/unknown-workspace`: no authorizing Session, and neither current nor Tab Session is borrowed |
 | `DSH-RESOURCE://File/session/s1/a` | `file` | a distinct record: addresses compare as strings, and `openResource` accepts only the canonical lower-case spelling that `fileAddressFor` emits |
 | `sidebar://guide` | — | `none`: a navigation address |
 | `/home/me/notes.md` | — | `none`: not a URL |
 
 ## Registering a provider
 
-The owner of a protocol declares its value type on `ResourceProtocolMap` and registers one provider inside its own `ctx.effect`, so the protocol lives exactly as long as the plugin ([provide a protocol](../../packages/client/resources/README.md#provide-a-protocol)). `open(address, { signal })` returns a stream of `RemoteResult` frames — the current state first, then one frame per change — and must stop when `signal` aborts. A failure is an `ok: false` frame carrying a `RemoteFailure`; a throw inside the stream is a programming error and is not caught. `reload(address)` is optional and asks the open stream for a fresh frame.

 A resource is alive while it has a holder: a subscribed `useResource`, or a pin. `ctx.resources.pin(address, signal)` keeps a resource open without subscribing until `signal` aborts, and an already-aborted signal pins nothing; the right Sidebar pins every open tab record's address for the record's life, so switching tabs unmounts a body without closing its stream. The first holder opens the provider's stream; the last release aborts it, discards the value, and returns the snapshot to `loading` (provider present) or `none` (absent). A frame the provider yields after that release is dropped, and the iterator is returned. `ctx.resources.source(address)` is the bare observable behind the hook, reference-stable per address, for callers outside React; reading its snapshot does not hold the resource ([lifecycle](../../packages/client/resources/README.md#lifecycle)).

 A body, title and guide replacement receive the framework-injected `useTabInfo()`. It returns `{ sidebar, panel, tab }`: `sidebar` holds `expanded` and `fullscreen`, `panel.id` names the containing pane, and `tab` contains its record fields plus `visible`, `navigation`, `signal`, and `actions`. Docked bodies are visible only while expanded and active; docked titles need only expansion; floats stay visible. `signal` aborts when the record disappears or the plugin unloads, not on hiding or Session switching. `tab.actions` provides `openResource`, `openTab`, and `close`, bound to the tab's own Session. Open placement defaults to its current pane; `revealIfOpened` defaults to `true`, and `replaceTab: true` replaces this record in the same history entry. Menu entries retain plain `tab` and `dismiss` owner parameters.
 
 `navigation.revision` increments on every navigation to the tab whether or not `params` changed, so a body can act on "navigated again" alone; it is `1` for a tab opened by address and `0` for a record nobody opened by address — a seeded guide, or a tab restored by undo. The Tab domain holds one occurrence per open record: a record that appears is pinned in the resource model, so switching tabs unmounts a body without dropping its content; a record that vanishes is aborted and dropped; a record restored by undo is a new occurrence ([Tab domain](../../packages/client/ui-sidebar-right/README.md#the-tab-domain)).
 
+## Document renderers
+
+The `text` tab is the shared Document Preview owner. Its [root registration](../../packages/client/ui-sidebar-textpreview/src/client/index.ts) declares `sidebar.right.tab.document` and provides `ctx.documentPreviews`. A renderer registers `DocumentPreviewDefinition` metadata in its own effect, then waits through `ctx.slots.inject('sidebar.right.tab.document', ...)` and registers its component with `key: definition.id` and its locale namespace. Changing the renderer does not change the tab or resource address; the [extension decision](../../.agents/notes/implemented/architecture/2026-09-08-document-preview-operations.md) separates preview policy from resource ownership.
+
+The [registry](../../packages/client/ui-sidebar-textpreview/src/client/document/registry.ts) records unique `id`, `extensions`, localized `title()`, `loading`, optional `priority`, and optional `wrap`. Case-insensitive suffix matching ranks `extension` (the default) before `builtin`, then longer suffixes before shorter ones, then registration order. Unlike tab-kind replacement, the registry keeps all implementations available; the toolbar lists matching alternatives and remembers the selection per tab. Unknown extensions use plain text. `loading` is `text-pages` or `bytes-complete`; `wrap` advertises support for the shared source-wrap control.
+
+[`DocumentPreviewProps`](../../packages/client/ui-sidebar-textpreview/src/client/document/contract.ts) derives from `PropsRuntime<'sidebar.right.tab.document'>`. The owner supplies the original `resourceAddress`, `content`, and current `wrap`: text content is `{ kind: 'text', text, pages: [{ offset, text, lines }], eof }`, with cumulative `text`; complete bytes are `{ kind: 'bytes', data }`, with `Uint8Array<ArrayBuffer>` data. These transient buffers are borrowed read-only and must not enter durable layout or Session JSON. PDF copies the bytes before Worker transfer, preserving the owner's buffer. The child receives the same framework-bound `useTabInfo` and the global metadata-only `useResource`. The parent reads through ordinary inject callbacks to `remote.workspaceFiles.read`/`readAll` and owns page appends, per-tab refresh, and loading status. HTML's own inject callback uses `readRelated`; Host code resolves paths. Markdown and code retain one incremental renderer across appends and settle at EOF; HTML and PDF receive complete bytes.
+
+Preview records its loaded version and the version observed when a read starts. Refresh rereads only that tab, without changing shared metadata or another tab's content. Reads are non-transactional; versions are opaque equality tokens, not ordered timestamps ([resource observation and Preview RPC](../../.agents/notes/implemented/architecture/2026-09-08-document-preview-operations.md)).
+
 ## Resource model
 
-The model is documented in [Client Resources](client-resources.md); this section states what the Sidebar relies on. A resource is one address, and a resource address is a `dsh-resource://<type>/…` URL whose lower-cased host is the protocol key. The protocol's owning client package registers one provider with `ctx.resources.register(provider)` for its own lifetime; a second provider for the same protocol throws ([provide a protocol](../../packages/client/resources/README.md#provide-a-protocol)). A provider is `{ protocol, open(address, { signal }), reload?(address) }`: `open` yields `RemoteResult` frames — the current state first, one frame per later change — and stops when `signal` aborts; a failure is an `{ ok: false, error }` frame, never a throw, and a throw inside the stream is a programming error the model does not catch.

-`useResource<P>(address)` is a global standard prop on every slot component, whatever its scope. It returns `{ status, value, failure, reload }`: `none` when the address's protocol has no provider or the address is not a resource address (`sidebar://guide` names no resource), `loading` until the first frame, `live` with the latest `ok` value, `failed` with the latest frame's failure beside the last value. `reload()` asks the provider for a fresh frame and is a no-op without one ([read a resource](../../packages/client/resources/README.md#read-a-resource)).

([read a resource](../../packages/client/resources/README.md#read-a-resource)).
 
-A resource stays open while it has a holder — a subscribed `useResource` or a `ctx.resources.pin(address, signal)`; the first holder opens the provider's stream, later holders share it and read the latest value at once, and the last release aborts the stream and discards the value. Streams carry metadata, not content: the `file` value is `{ absolutePath, version, bytes?, changed }`, and a consumer reads file text itself, by page, through the Workspace Files service ([lifecycle](../../packages/client/resources/README.md#lifecycle)).

Streams carry metadata, not content: the `file` value is `{ absolutePath, version, bytes? }`, and a consumer reads file text itself, by page, through the Workspace Files service ([lifecycle](../../packages/client/resources/README.md#lifecycle)).
 
 ## Workspace Files
 
 The Host `ctx.workspaceFiles` service and the generated `workspaceFiles` Remote namespace answer for files inside the addressed Session's workspace root: `stat(path)` returns `{ absolutePath, version, bytes? }`; `read(path, { offset?, limit? })` returns one page of lines (`offset` 1-based, `limit` capped by the configured page size) as `{ …stat, offset, text, eof }`; `readBytes(path, { offset?, length? })` returns one raw byte window (`offset` 0-based, `length` capped by the configured byte limit) as base64 `{ …stat, offset, data, eof }` with no text decoding; `list(path)` returns a directory's direct children (`name`, `type: 'file' | 'directory' | 'other'`, `size?`) cut to the configured cap with `truncated` set; `changes()` yields `{ kind: 'ready' }` once subscribed, then `{ kind: 'change', change }` frames whose payload is `{ absolutePath, version }` or `{ absolutePath, absent: true }` ([README](../../packages/api/workspace-files/README.md#use-this-package)). Every call passes the same four gates — the path is inside the workspace root, symlinks are refused, page, window, and entry caps hold, `read`'s text is UTF-8 — and fails with a `workspace-file/*` error code otherwise ([failures](../../packages/api/workspace-files/README.md)).
 
-[`dsh-api-workspace-files`](../../packages/api/workspace-files/README.md) registers the `file` provider and declares `ResourceProtocolMap.file`. It sends a Session address's relative path unchanged to the Host and binds change filtering to the first successful `stat.absolutePath`. It waits for the Host's `ready` frame before stat, retaining changes delivered during that read. An absolute address uses the current Session; only its absence produces Client `workspace-file/unknown-workspace`. No Client `cwd` is required.
+[`dsh-api-workspace-files`](../../packages/api/workspace-files/README.md) registers the `file` provider, with `ResourceProtocolMap.file` directly naming `WorkspaceFileStat`. A Session address carries the authorizing Session and a relative or absolute path, passed unchanged to the Host for resolution. The provider waits for Host `ready` before stat and filters changes by `stat.absolutePath`. Bare `absolute` addresses have no authorizing Session and fail with `workspace-file/unknown-workspace`, without borrowing current or Tab Session. Any UI, including Global components, shares the observation for the same complete address. Preview's ordinary Remote callbacks use the Session in that address; Host `readAll` and `readRelated` remain, and Preview's `rpc.ts` decodes byte results.
 
 ## Shipped types
 
 - **`guide`** — `builtin`, opened as `openTab('guide')`. A centred title, one line, and one entry box per `guide` entry the registered types contributed, in `order`; picking a box opens the contributing type as a page in the guide tab's place. A pane holds at most one guide tab, every new pane is seeded with one, and the strip's add control appears only while its pane has none ([guide](../../packages/client/ui-sidebar-right/README.md#the-guide)).
-- **`text`** — `fallback`, `dsh-resource://file/**`. Reads metadata through `useResource<'file'>` and the file's lines by page through `read`; honours `params.line` on every navigation; keeps pages, scroll, and wrap in its own store ([README](../../packages/client/ui-sidebar-textpreview/README.md)).
+- **`text`** — `fallback`, `dsh-resource://file/**`, claiming Session addresses only. Document Preview observes metadata through `useResource<'file'>`, loads content through Remote callbacks, and owns renderer selection, the toolbar, per-tab refresh, scroll, and source navigation; unknown extensions render as plain text ([README](../../packages/client/ui-sidebar-textpreview/README.md)).
 - **`files`** — `builtin`, opened as `openTab('files')`. The workspace directory tree, listed lazily through `list`, opening a file with `tab.actions.openResource(fileAddressFor(sessionId, root, path))` into its own pane ([README](../../packages/client/ui-sidebar-files/README.md)).

 ## Summary
 
-Use this package to browse and inspect files within a Session's workspace from the web client. It reads UTF-8 text one page of lines at a time, reads raw bytes in bounded windows, reports file versions and sizes, lists direct directory children, and streams changes caused by Agent file operations. Every operation stays within the workspace root selected for the addressed Session, independent of the filesystem backend's working directory. Client components can also follow live file metadata and build the Sidebar file tree through the shared Remote API.

 ### Addressing and paths
 
-`read`, `stat`, and `list` accept a workspace path that is absolute or relative to the Session's workspace root. Two path vocabularies leave the service, and each method uses exactly one: `read`, `stat`, and `changes` report a file as its absolute path in the filesystem's execution world, symlinks resolved (`WorkspaceFileStat.absolutePath`, `WorkspaceFileChange.absolutePath`), because their consumer is the Client resource system, which follows changes by that path; `list` reports the listed directory as a workspace path relative to the root — empty for the root itself — because its consumer is a tree rooted there, and a child's path is that value joined with the entry name by `/`.

 ### The four gates
 
-Every read, stat, and listing passes four gates in this order. First, `lstat` inspects the path itself before anything follows it: a symlink, wherever it points, fails `read` and `stat` with `not-regular-file` and `list` with `not-directory`, each carrying the entry's `kind`. Second, containment: the path resolves to a target and `ctx.fs.contains(root, target)` decides, so a `..` traversal or an absolute path outside the root fails with `outside-workspace` — never a string-prefix comparison, which cannot see a realpath that leaves the root. Third, the caps: a page whose text exceeds `maxBytes` fails with `too-large` instead of arriving shortened — the file itself has no size cap — while `maxEntries` cuts a listing and sets `truncated`. Fourth, text: content that is not UTF-8 up to the end of the page, or a page that carries a NUL byte, fails with `not-text`; bytes past the page are not inspected. A missing path fails with `not-found`; an empty path is a `gateway/bad-request`.

 ### Client file resources
 
-The browser export registers the `file` provider into `ctx.resources` and requires `resources`, `remote`, `remote.workspaceFiles`, and `sessions`. The bundle's single `workspace-files` row supplies both faces; the Client has no separate configuration. A component follows a file through its standard `useResource<'file'>(address)` prop and reads `{ absolutePath, version, bytes?, changed }`; content is fetched separately through the paged methods.
+The browser export registers the `file` provider into `ctx.resources` and requires `resources`, `remote`, and `remote.workspaceFiles`. The bundle's single `workspace-files` row supplies both faces; the Client has no separate configuration. A component reads `WorkspaceFileStat { absolutePath, version, bytes? }` metadata through `useResource<'file'>(address)` and fetches content separately through Remote reads. Any UI, including Global components, shares the observation for the same complete address.
 
-A `session/<sessionId>/<path>` resource address sends its relative path unchanged to the Host, which resolves and confines it against that Session's workspace root; the Client needs no Session `cwd`. An `absolute/<path>` address reads through the current Session. Both use the `dsh-resource://file/` grammar in [workspace-path](../../util/workspace-path/README.md). An absolute address without a current Session produces `workspace-file/unknown-workspace`; an unsupported address produces `workspace-file/unsupported-address`. These Client failures end the stream and make reload a no-op.
+A `session/<sessionId>/<path>` address carries the authorizing Session and a relative or absolute path; leading slashes are preserved, as in `dsh-resource://file/session/s//etc/hosts`. The Host receives the path unchanged and owns resolution and access checks; the Client needs no Session `cwd`. `absolute/<path>` remains parseable but has no authorizing Session and fails with `workspace-file/unknown-workspace`, without borrowing current or Tab Session. Unsupported addresses fail with `workspace-file/unsupported-address`. [Workspace-path](../../util/workspace-path/README.md) owns the grammar; the generic Resource layer knows only the address and `signal`.
 
-The provider waits for the Host's `ready` frame before its first `stat`, queues changes during the read, then binds the follower to `stat.absolutePath`. Both queued and live changes match that Host-returned path. A new write version raises `changed` while retaining the last byte size; duplicate versions are ignored. An absent notice or reload re-stats the file. A failed stat keeps the address followed; a later write or reload can recover it, and any Session write can trigger a retry before the first successful path binding. Reload clears `changed`; a Host-triggered re-stat keeps it raised. Frames are `RemoteResult` values, and programming exceptions remain uncaught.

Frames are `RemoteResult` values, and programming exceptions remain uncaught.
 
 One supervised `changes` stream serves every followed file in a Session. Followers match absolute paths with backslashes normalized to slashes. Carrier loss reconnects through the Gateway supervisor; a Host-ended or terminally failed feed ends its followers and leaves their last metadata readable until reopened. The last follower leaving disposes the stream, a successor waits for that disposal, and plugin teardown awaits all pending closes. The provider declares `ResourceProtocolMap.file`; the text preview declares its Sidebar line-navigation parameters.

 - **`maxEntries` bounds the answer, not the listing** — `list` asks `ctx.fs.listDir` for every child and cuts the array afterwards, so a directory far above the cap still costs the Host the whole listing (on `fs-local`, one stat per child); bounding that work needs a limit on the filesystem seam's `listDir`.

 1. **Everything a render reads that can change outside React arrives through a framework hook** (rule 4 above). Event-handler code may read live snapshots (e.g. `keyboard.snapshot`); render code subscribes.
 2. **Business components contain no subscription machinery** — no `useSyncExternalStore`, no manual subscribe wiring, no mirroring an external snapshot into local state or a second store. Give each reactive fact its owning channel instead: registrant-private → the inject `hooks` compartment; cross-entry or remount-surviving → a declared store; per-session standard → `sessions.provide`.
 3. **Data-access ladder** — resolve needs in this order: framework hooks (standing seats + provide/inject-bound `use<Name>`) → a declared store (`useStore`/`actions`) → inject callbacks → anything else is a new framework extension point and needs main-thread arbitration.
-4. **UI domains share only JSON-compatible data and callbacks.** Owner props, injected values, store state, and provide contributions are plain serializable data or callbacks over such data. The injected `hooks` compartment is the only place for bare observables, and components never receive those sources directly. Route ReactNode content through a slot; do not add ReactNode-valued owner props or injected members (the composer's existing `accessory`/`overlay`/`leftItems`/`rightItems` fields remain until they move to slots).
+4. **UI domains share JSON-compatible data and callbacks.** Owner props, injected values, store state, and provide contributions use these values.

 5. **An observable source keeps two identities stable**: the source object itself (hook binding is cached per source), and its snapshot between changes (`getSnapshot` returns the same reference until the fact moves).
 6. **Whoever rebuilds a published value republishes it through the same source in the same step**, and a registration path that can run after consumers exist notifies the live consumers as part of registering.

 ### Read a resource
 
-Every slot component receives `useResource` in its props. `useResource<P>(address)` names the protocol as the type argument and returns `{ status, value, failure, reload }`: `none` when no provider is registered for the address's protocol (or the address is not a `dsh-resource://` URL), `loading` while the provider has not yielded, `live` with the latest `ok` frame's value, and `failed` when the latest frame reported a failure, with that failure beside the last value. `reload()` asks the provider for a fresh value and is a no-op without one. Subscribing through the hook is what holds the resource open; a component that mounts while another holder keeps the resource alive reads the latest value at once.

 ## The guide
 
-The guide tab is a centred title, one line under it, and one entry box per `guide` entry the registered types contributed, in `order`. Picking a box calls `tab.actions.openTab(entry.kind, { replaceTab: true })`, so the guide gives way to the page it opened. A pane holds at most one guide tab. The strip's add control is drawn only while its pane holds none and opens one there with `openTab('guide', { paneId, revealIfOpened: false })`, so a guide in another pane does not capture the click; opening the guide into a pane that already has one focuses it instead; a guide dragged, dropped, or docked into such a pane merges into it — the arriving guide closes and the pane's own is focused; `duplicateTab` on the guide records nothing. A split or an emptied root pane seeds a guide through the kit's factory, one per new pane. A plain `openTab('guide')` keeps the tree-wide reveal every open has. The product allows two horizontal panes, initially equal, with divider ratios limited to 20%–80%. Insufficient width blocks a new split; with two panes already present, a body drop moves the tab between panes instead of creating a third. At the two-pane limit, split controls are hidden; closing back to one pane restores them.
+Default pages depend on the number of registered guide entries, not the number of tab types or open tabs. Exactly one entry opens its page directly (Files in the shipped composition); zero or multiple entries open the guide. Each single-entry default remains non-closable when other tabs are added. Any pane's last tab is also non-closable; other tabs can close. The chip, context menu, and `close` API apply the same rule. Explicitly adding a guide still opens the guide, even with one entry.

+引导 tab 是一个居中标题、其下一行说明，以及各已注册类型贡献的每个 `guide` 条目一个入口框，按 `order` 排列。选中一个框会调用 `tab.actions.openTab(entry.kind, { replaceTab: true })`，于是引导页让位给它打开的页。一个格最多持有一个引导 tab。tab 条的添加控件只在该格没有引导 tab 时绘制，并以 `openTab('guide', { paneId, revealIfOpened: false })` 在该格打开一个，这样别的格里的引导页不会截走这次点击；把引导页开进已有引导页的格则改为聚焦它；把引导页拖入、放入或收回到这样的格会合并进去——来者关闭，该格自己的被聚焦；对引导页 `duplicateTab` 不记录任何东西。分栏或被清空的根格使用相同的默认页规则，每个新格一个 tab。普通的 `openTab('guide')` 保留每次打开都有的整树聚焦。产品最多保留左右两格，默认均分，分隔条限定20%～80%。宽度不足以容纳两格时不允许新分栏；已有两格时，正文拖放用于跨格移动，不再创建第三格。 达到两格上限时隐藏分栏控件；关闭回单格后恢复。

 ## Summary
 
-The right Sidebar's plain-text viewer: one workspace text file, read one page of lines at a time, with line navigation, wrap, and reload. It is the fallback type for every `file` resource address, and the template for a tab type shipped from outside `ui-sidebar-right`: every import from the Sidebar is a type, the file's metadata comes from the shared `file` resource, the text is the type's own business, and the type's controls live in its own body.
+Preview workspace documents in the right Sidebar and choose among registered renderers without opening another tab. Markdown and code receive accumulated text pages; PDF and HTML receive complete bytes; unknown file extensions use plain text. The tab owns loading, file status, renderer selection, wrap, and reload, while document bodies register through the same metadata registry and child slot. The Sidebar tab kind is `text`.

 ## What it registers
 
-- **The type** — `ctx.sidebarRightTabs.register(...)` with id `@deepseek-ai/dsh-client-ui-sidebar-textpreview` (this implementation's identity in the tab system, and the key its body registers under), kind `text`, pattern `dsh-resource://file/**`, band `fallback`. A type registered at the `extension` or `builtin` band for a narrower pattern (say `*.png`) takes those addresses; everything else lands here. The whole address is the content identity, so two files with one name in different directories, or one path under two sessions, are two tabs; the decoded basename is the tab title.
-- **The body** — the keyed `sidebar.right.pane.tab` seat under the type's id. Its header row shows the Host's absolute path and exposes its full value in a tooltip, with the type's two controls at its end: a wrap toggle (on by default; long lines wrap until the reader turns it off, per tab) and a reload button. The Sidebar's tab strip carries no controls of this type. The body takes the pane body's full height: the header row stays put and the file body below is the one scroller, so a short file leaves no unstyled space and a long file scrolls under a fixed path. Until metadata provides an absolute path, the header uses the requested path.
-- **One store and one face**, session-scoped and bucketed by tab id. The store holds the pages read so far (keyed by the 1-based line each starts at, with the file version they belong to), the end-of-file flag, the read in flight or its failure, and the view: scroll offset, wrap (initially on), and the navigation revision the body last answered. The face (`loadPage`, `reloadPages`) performs the reads and writes through the store's actions. The bucket is forgotten when the owner's `signal` aborts, which is when the tab record is gone.
+- **The type** — `ctx.sidebarRightTabs.register(...)` with id `@deepseek-ai/dsh-client-ui-sidebar-textpreview` (this implementation's identity in the tab system, and the key its body registers under), kind `text`, pattern `dsh-resource://file/**`, band `fallback`. `canOpen` accepts only Session addresses, whose paths may be relative or absolute; bare `absolute` addresses are not claimed. A type registered at the `extension` or `builtin` band for a narrower pattern (say `*.png`) takes those addresses; other supported files land here. The whole address is the content identity, so two files with one name in different directories, or one path under two sessions, are two tabs; the decoded basename is the tab title.
+- **The body** — the keyed `sidebar.right.pane.tab` seat under the type's id. Its fixed header shows the Host's absolute path when available, otherwise the requested path, and a dropdown for matching renderers plus plain text. A wrap toggle appears only when the selected renderer declares `wrap: true`; the per-tab preference starts on. Reload stays in this header, not the Sidebar's tab strip. The shared body below owns document scrolling.
+- **Shared loading and view state**, session-scoped and bucketed by tab id. The store holds accumulated pages or complete bytes, read and observed versions, loading/failure state, renderer choice, scroll offset, wrap, and the answered navigation revision. The ordinary inject face calls Remote readers and writes through declared store actions. Reloads and loading-mode changes retire older requests; the tab's abort signal forgets its state.
+
+Document implementations register metadata with `ctx.documentPreviews.register({ id, extensions, priority, title, loading, wrap? })` and a body under the same `id` in the keyed, Session-scoped `sidebar.right.tab.document` child slot. Own both registrations with effects and wait for the child slot through `ctx.slots.inject`. Bodies receive `resourceAddress`, prepared `content`, `wrap`, and the standard `useTabInfo`/`useResource` hooks; they do not receive a custom resource loader. Metadata declares `loading: 'text-pages'` or `'bytes-complete'`. The registry retains all matching alternatives: `extension` (the default) ranks above `builtin`, then longer suffixes rank first, then registration order. The dropdown preserves a selected implementation while it remains available; removing it selects the next candidate. Builtin bodies use these same registrations.

 ## Addresses
 
-A tab's address is `dsh-resource://file/session/<sessionId>/<path relative to that session's workspace root>` or `dsh-resource://file/absolute/<absolute path without its leading />` (a URI whose authority is the resource protocol, `file`, and whose path opens with the scope), built by `fileAddressFor` in `@deepseek-ai/dsh-util-workspace-path` and read back by `parseFileAddress`; every segment is component-encoded, and this package never splits the string itself. `hostFileOf` in `rpc.ts` turns the address into the session and path the endpoint takes: a `session` address reads under the session it names, with the relative path the Host resolves against that session's workspace root; an `absolute` address reads under the session the slot was mounted for, with the absolute path, and the Host's workspace confinement still applies. A malformed address throws, because the registry routes every `file` address to this type and a caller building one is expected to use the helper.
+A tab uses the Session address built by `fileAddressFor`, carrying a relative or absolute path. `hostFileOf(address)` takes the Session only from that address, with no external Session argument; neither current nor Tab Session is borrowed. The Host resolves file and related paths and enforces confinement. Metadata for the same complete address is shared by every UI, including Global components. The [Workspace Files README](../../api/workspace-files/README.md) owns these rules; renderer selection does not change the navigation address.
 
 <a id="how-it-reads"></a>
 ## How it reads
 
-The body reads its record, navigation and lifetime through `useTabInfo().tab`. Metadata and content come from different places:
+The body reads its record, navigation and lifetime through `useTabInfo().tab`. `useResource<'file'>(tab.contentId)` supplies metadata; ordinary inject callbacks supply content reads:
 
-- `useResource<'file'>(tab.contentId)`, the standard hook from `@deepseek-ai/dsh-client-resources`, yields `{ absolutePath, version, bytes, changed }` from the `file` provider in `@deepseek-ai/dsh-api-workspace-files`. The body reads `changed` and the failed state: when the agent wrote the file after the last `stat`, a bar announces it with a reload button, and when the resource is `failed` — the file gone, or the Host refusing it — a failure bar takes that place with the failure's line and the same reload button, ahead of any pending `changed`. Either way the pages already read stay on screen: the text is never replaced under the reader.
-- Pages come from `remote.workspaceFiles.read(sessionId, path, { offset }, signal)`, bound in `rpc.ts` and called by the face with the session and path the address names. The first mount reads the first page; a **Load more** button at the end of the loaded text reads the next until `eof`. Each page carries its line count (`lines`), which is how one empty line and a page past the end read differently. A first page from a newer file version replaces the pages of the older one; a later page from a newer version is not adopted — the walk restarts from the first page, so the body never mixes two versions. A failed page shows one sentence per `workspace-file/*` code (`not-found`, `outside-workspace`, `too-large` for a page over the byte cap, `not-text`, `not-regular-file`) or the transport's own message, with a retry for the same page.
-- **Reload** — the change bar's button and the header's reload control both call the resource's `reload()` (a fresh `stat`, which clears `changed`) and the face's `reloadPages` (drop the pages, read the first one again). A reload retires the reads still in flight — the face keeps a request generation per tab, and a page settling from an older generation writes nothing. The scroll offset is kept, so the reader stays where they were.
+- The resource snapshot contains only `status`, `value`, and `failure`; `value` is `WorkspaceFileStat` metadata. Content reads do not wait for the first metadata frame once the provider is available. Observation failures take precedence over Preview's change notice; neither automatically replaces loaded content.
+- **Text pages** — plain text, Markdown, and code read through an inject callback to `remote.workspaceFiles.read(sessionId, path, { offset }, signal)`. The first mount reads page one; scrolling to the body end or **Load more** requests the next page until `eof`. The owner delivers the accumulated prefix as `{ kind: 'text', text, pages, eof }`, including source offsets and line counts. Markdown and code render that prefix incrementally; they do not render each page as a separate document. A newer-version page past page one restarts from the beginning rather than mixing versions. Failures retain loaded content and offer a retry.
+- **Complete bytes** — PDF and HTML use an inject callback to `remote.workspaceFiles.readAll(sessionId, path, signal)`. `rpc.ts` decodes the wire base64 into `data: Uint8Array<ArrayBuffer>` for `{ kind: 'bytes', data }`. The Host's `maxFileBytes` cap rejects oversized files rather than truncating them. PDF copies retained bytes before worker transfer, keeping the Preview buffer usable. Bytes stay in transient view state, never persisted layouts or Session JSONL. Loading-mode changes retire previous results.
+- **Reload** — only the current Preview tab rereads through its Remote callbacks, preserving its scroll preference and retiring older requests. Its change notice compares the read version and the observation captured at read start with later `resource.value.version`; an already observed version does not become a new change after refresh. Reads neither refresh shared metadata nor clear another tab's notice.
 
-Copy comes from the `sidebarTextpreview` locale namespace.
+HTML runs in a Blob iframe with exactly `sandbox="allow-scripts"`, without `allow-same-origin`; scripts cannot access the parent application's origin or file reader. The renderer loads directly declared relative `.js` classic scripts and `.css` stylesheets through its ordinary inject callback to `remote.workspaceFiles.readRelated`, under the configured limits. Host code resolves the related path; `rpc.ts` decodes the returned bytes. Inside the renderer, base64 is used only to embed the iframe bootstrap payload in script text. A `<base href>` leaves dependency resolution to the browser, as do HTTPS resources. Local module imports, CSS `url()`/`@import`, and dynamic `fetch` do not use Host file access. Read failures, invalid UTF-8, or exceeded limits fail the preview rather than publishing a partial asset package. Replacing or unmounting the document releases its Blob URL.
+
+Shared copy comes from `sidebarTextpreview`; each builtin renderer owns its localized labels.
+
+Initial reads, additional pages, and HTML/PDF preparation share a loading indicator that respects reduced-motion preferences. Loaded pages stay visible while another page loads. Code previews show source line numbers by default without including them in copied text; plain text uses the same font size and line height as code.
 
 <a id="navigation"></a>
 ## Navigation
 
-`ctx.sidebarRight.openResource(address, { params: { line } })` — the `read` tool row passes its `offset` this way — arrives as `navigation.params`, which the body narrows to the `file` resource type's declared parameters (`SidebarRightResourceParamsMap['file']`, `{ line?: number }`, 1-based) without runtime validation: `params` is a typed same-process value. If the loaded pages do not reach that line, the body reads the next page, again, until they do or the file ends; then it scrolls the line to the top and marks it, once per `navigation.revision`. A body remounting for the same revision restores the reader's scroll offset instead. Opening the same file again without `revealIfOpened: false` focuses the existing tab and delivers the new parameters as a new revision.
+`ctx.sidebarRight.openResource(address, { params: { line } })` carries a 1-based source line through the `file` parameters. In `text-pages` mode, the owner loads sequential pages until that line or EOF, then locates a source-line anchor if the renderer supplies one; plain text supplies these anchors. Byte-mode renderers do not consume source-line navigation. Each navigation revision is answered once; remounting restores the shared scroll offset. Opening the same file without `revealIfOpened: false` focuses its existing tab and delivers a new revision.

 ## 概述
 
-右侧 Sidebar 的纯文本查看器：一个工作区文本文件，一次读一页行，带行号导航、换行与重新读取。它是每个 `file` 资源地址的兜底类型，也是 `ui-sidebar-right` 之外交付的 tab 类型的样板：来自 Sidebar 的每个 import 都是类型，文件的元数据来自共享的 `file` 资源，正文是类型自己的事，类型的控件住在自己的体里。
+在右侧 Sidebar 预览工作区文档，无需另开 tab 即可切换已注册的渲染器。Markdown 和代码接收累计文本页；PDF 和 HTML 接收完整字节；未知文件扩展名使用纯文本。tab 负责加载、文件状态、渲染器选择、换行和重新载入，文档正文通过同一元数据注册表与子 slot 注册。Sidebar tab 的 kind 为 `text`。

 ## 注册了什么
 
-- **类型** —— `ctx.sidebarRightTabs.register(...)`，id 为 `@deepseek-ai/dsh-client-ui-sidebar-textpreview`（这个实现在 tab 系统里的唯一键，也是其体注册所用的 key），kind `text`，pattern `dsh-resource://file/**`，档位 `fallback`。在 `extension` 或 `builtin` 档以更窄 pattern（比如 `*.png`）注册的类型接走那些地址；其余一切落到这里。整个地址就是内容身份，所以不同目录下同名的两个文件、或同一路径在两个会话之下，是两个 tab；解码后的 basename 是 tab 标题。
-- **体** —— keyed 坑位 `sidebar.right.pane.tab`，键为类型的 id。它的头部行显示 Host 的绝对路径，并在提示中保留完整值，末端是类型的两个控件：换行开关（默认开；长行折行直到读者关掉它，按 tab 记）与重新读取按钮。Sidebar 的 tab 条不承载这个类型的任何控件。体占满 pane 体的全部高度：头部行不动，其下的文件体是唯一的滚动者，于是短文件不留没有样式的空白，长文件在固定的路径下滚动。 元数据尚未提供绝对路径时，头部使用请求路径。
-- **一个 store 与一个 face**，会话作用域、按 tab id 分桶。store 持有已读的页（以每页起始的 1 起行号为键，连同它们所属的文件版本）、文件末尾标志、进行中的读取或其失败，以及视图：滚动位置、换行（初始为开）、体最近答过的导航 revision。face（`loadPage`、`reloadPages`）执行读取并经 store 的 action 写入。owner 的 `signal` abort 时——即 tab 记录消失时——桶被忘掉。
+- **类型** —— `ctx.sidebarRightTabs.register(...)`，id 为 `@deepseek-ai/dsh-client-ui-sidebar-textpreview`（这个实现在 tab 系统里的唯一键，也是其体注册所用的 key），kind `text`，pattern `dsh-resource://file/**`，档位 `fallback`。`canOpen` 只接受 Session 地址，其中路径可为相对或绝对路径；不认领裸 `absolute` 地址。在 `extension` 或 `builtin` 档以更窄 pattern（比如 `*.png`）注册的类型接走那些地址；其他受支持文件落到这里。整个地址就是内容身份，所以不同目录下同名的两个文件、或同一路径在两个会话之下，是两个 tab；解码后的 basename 是 tab 标题。
+- **正文** —— keyed slot `sidebar.right.pane.tab`，键为类型的 id。固定头部在可用时显示 Host 的绝对路径，否则显示请求路径，并提供匹配渲染器及纯文本的下拉选择。仅当所选渲染器声明 `wrap: true` 时显示换行开关；该偏好按 tab 保存，初始开启。重新载入仍在此头部，不放入 Sidebar 的 tab 条。下方的共享正文区域负责文档滚动。
+- **共享加载与视图状态**，会话作用域、按 tab id 分桶。store 持有累计页或完整字节、读取与观察版本、加载/失败状态、渲染器选择、滚动位置、换行和已响应的导航 revision。普通 inject face 调用 Remote 读取，并经声明的 store action 写入。重新载入和加载模式变化会淘汰旧请求；tab 的中止信号清理其状态。
+
+文档实现在 `ctx.documentPreviews.register({ id, extensions, priority, title, loading, wrap? })` 注册元数据，并以相同 `id` 向 keyed、Session 作用域的子 slot `sidebar.right.tab.document` 注册正文。两处注册都由 effect 持有，通过 `ctx.slots.inject` 等待子 slot。正文接收 `resourceAddress`、准备好的 `content`、`wrap` 和标准 `useTabInfo`/`useResource` 钩子，不接收自定义资源加载器。元数据声明 `loading: 'text-pages'` 或 `'bytes-complete'`。注册表保留所有匹配备选：`extension`（默认）优先于 `builtin`，随后按更长的后缀、再按注册顺序排列。所选实现仍可用时，下拉选择保持不变；移除后选择下一个候选。内置正文也使用相同注册方式。

 ## 地址
 
-tab 的地址是 `dsh-resource://file/session/<sessionId>/<相对该会话工作区根的路径>` 或 `dsh-resource://file/absolute/<去掉前导 / 的绝对路径>`（一个 URI，authority 是资源协议 `file`，路径以作用域开头），由 `@deepseek-ai/dsh-util-workspace-path` 的 `fileAddressFor` 构造、`parseFileAddress` 读回；每段都做 component 编码，本包从不自己拆这个串。`rpc.ts` 里的 `hostFileOf` 把地址变成端点所需的会话与路径：`session` 地址在它命名的会话下读取，相对路径由 Host 对该会话的工作区根解析；`absolute` 地址在坑位被挂载的会话下以绝对路径读取，Host 的工作区限制照样适用。畸形地址直接抛错，因为注册表把每个 `file` 地址都路由给这个类型，造地址的调用方本应使用助手。
+tab 使用 `fileAddressFor` 构造的 Session 地址，携带相对或绝对路径。`hostFileOf(address)` 仅从地址取得 Session，不接收外部 Session 参数，也不借用当前或 Tab Session。Host 解析文件及关联路径，并执行包含检查。任何 UI（包括 Global 组件）都共享同一完整地址的元数据。[Workspace Files README](../../api/workspace-files/README.zh.md)定义这些规则；渲染器选择不改变导航地址。

 ## 怎么读
 
-正文通过 `useTabInfo().tab` 读取记录、导航和生命周期。元数据与内容来自不同的地方：
+正文通过 `useTabInfo().tab` 读取记录、导航和生命周期。`useResource<'file'>(tab.contentId)` 提供元数据，普通 inject 回调提供内容读取：
 
-- `useResource<'file'>(tab.contentId)`——来自 `@deepseek-ai/dsh-client-resources` 的标准 hook——从 `@deepseek-ai/dsh-api-workspace-files` 的 `file` 提供方得到 `{ absolutePath, version, bytes, changed }`。体读 `changed` 与失败态：agent 在上次 `stat` 之后写了文件时，一条提示带着重新载入按钮出现；资源为 `failed` 时——文件没了，或 Host 拒绝——一条失败条占据同一位置，显示失败句与同一个重新载入按钮，并优先于尚未处理的 `changed`。两种情况下已读的页都留在屏幕上：正文绝不在读者眼前被替换。
-- 页来自 `remote.workspaceFiles.read(sessionId, path, { offset }, signal)`，在 `rpc.ts` 绑定、由 face 以地址所命名的会话与路径调用。首次挂载读第一页；已加载文本末尾的 **加载更多** 按钮读下一页直到 `eof`。每页带着自己的行数（`lines`），单个空行与越过文件末尾的页由此区分。来自更新文件版本的第一页替换旧版本的页；更新版本的后续页不被采用——从第一页重新走一遍，于是体永不混合两个版本。失败的页按 `workspace-file/*` 错误码各显示一句（`not-found`、`outside-workspace`、超过字节上限的页 `too-large`、`not-text`、`not-regular-file`）或传输层自己的消息，并带一个重读同一页的重试。
-- **重新载入** —— 变更提示条的按钮与头部的重新读取控件都调用资源的 `reload()`（重新 `stat`，清掉 `changed`）与 face 的 `reloadPages`（丢掉所有页，重读第一页）。重载淘汰仍在飞的读取——face 按 tab 记请求代次，旧代次结算的页什么也不写。滚动位置保留，读者停在原处。
+- 资源快照仅包含 `status`、`value` 和 `failure`；`value` 是 `WorkspaceFileStat` 元数据。提供方可用后，内容读取无需等待首个元数据帧。观察失败优先于 Preview 的变更提示显示；两者都不会自动替换已加载内容。
+- **文本页** —— 纯文本、Markdown 和代码通过 inject 回调调用 `remote.workspaceFiles.read(sessionId, path, { offset }, signal)`。首次挂载读取第一页；滚动到正文末尾或点击 **加载更多** 会读取下一页，直到 `eof`。owner 以 `{ kind: 'text', text, pages, eof }` 提供累计前缀，包含源码行偏移和行数。Markdown 和代码增量渲染此前缀，不把每页当成独立文档。第一页之后到达的更新版本页会使读取从头开始，避免混合版本。失败时保留已加载内容并提供重试。
+- **完整字节** —— PDF 和 HTML 通过 inject 回调调用 `remote.workspaceFiles.readAll(sessionId, path, signal)`。`rpc.ts` 将线路上的 base64 解码为 `data: Uint8Array<ArrayBuffer>`，供 `{ kind: 'bytes', data }` 使用。Host 的 `maxFileBytes` 上限拒绝超大文件，不截断。PDF 在传给 worker 前复制保留的字节，使 Preview 缓冲区仍可使用。字节仅保存在临时视图状态中，绝不进入持久布局或 Session JSONL。加载模式变化会淘汰先前结果。
+- **重新载入** —— 仅当前 Preview tab 通过自己的 Remote 回调重读，保留滚动偏好并淘汰旧请求。变更提示将读取版本及起读时的观察版本与后续 `resource.value.version` 比较；刷新前已观察到的版本不会被当成新变化。读取既不刷新共享元数据，也不清除其它 tab 的提示。
 
-文案来自 `sidebarTextpreview` locale 命名空间。
+HTML 在 Blob iframe 中运行，沙箱属性严格为 `sandbox="allow-scripts"`，不含 `allow-same-origin`；脚本无法访问父应用的源或文件读取接口。渲染器在配置上限内，通过普通 inject 回调调用 `remote.workspaceFiles.readRelated`，加载直接声明的相对 `.js` 经典脚本和 `.css` 样式表。Host 代码解析关联路径，`rpc.ts` 解码返回的字节。在渲染器内部，base64 仅用于把 iframe 引导载荷嵌入脚本文本。`<base href>` 将依赖解析交给浏览器，HTTPS 资源也由浏览器处理。本地模块 import、CSS `url()`/`@import` 和动态 `fetch` 不使用 Host 文件访问。读取失败、无效 UTF-8 或超出上限都使预览失败，不发布部分资源包。替换或卸载文档会释放其 Blob URL。
+
+共享文案来自 `sidebarTextpreview`；各内置渲染器拥有自己的本地化标签。
+
+首次读取、追加页及 HTML/PDF 准备共用加载指示器，并遵循减少动态效果偏好。下一页加载期间保留已显示的内容。代码预览默认显示源码行号，但复制文本不包含行号；纯文本与代码使用相同字号和行高。
 
 <a id="navigation"></a>
 ## 导航
 
-`ctx.sidebarRight.openResource(address, { params: { line } })`——`read` 工具行以此传它的 `offset`——以 `navigation.params` 到达，体把它收窄为 `file` 资源类型声明的参数（`SidebarRightResourceParamsMap['file']`，`{ line?: number }`，1 起），不做运行时校验：`params` 是同进程的类型化值。已加载的页够不到该行时，体读下一页，再读，直到覆盖它或文件结束；然后把该行滚到顶部并标记，每个 `navigation.revision` 一次。同一 revision 下重新挂载的体恢复读者的滚动位置而不再跳。不带 `revealIfOpened: false` 再次打开同一文件时聚焦已有 tab，并把新参数作为新 revision 送达。
+`ctx.sidebarRight.openResource(address, { params: { line } })` 通过 `file` 参数携带 1 起算的源码行号。在 `text-pages` 模式下，owner 顺序加载到该行或 EOF；渲染器提供源码行锚点时，再定位到对应锚点，纯文本提供这些锚点。字节模式渲染器不消费源码行导航。每个导航 revision 只响应一次；重新挂载恢复共享滚动位置。不带 `revealIfOpened: false` 打开同一文件时聚焦已有 tab，并送达新 revision。

 ## File addresses
 
-A resource address is `dsh-resource://<type>/…`, and the type — the URI host — is the resource protocol key (`file`, or one a plugin declares in `ResourceProtocolMap`); any other scheme is a navigation protocol, defined elsewhere. A file address has one of two scopes. `dsh-resource://file/session/<sessionId>/<path>` names a file by its path relative to that Session's workspace root (`dsh-resource://file/session/abc123/src/notes.txt`), which the Host resolves against the root it holds for the Session. `dsh-resource://file/absolute/<path>` names a file by its absolute path with the leading `/` dropped (`dsh-resource://file/absolute/home/ys/notes.txt` on POSIX, `dsh-resource://file/absolute/C:/x/y.txt` for a Windows drive, `dsh-resource://file/absolute//server/share/y.txt` for a UNC path, whose empty first segment keeps its identity); it carries no Session, so the reader's own Session resolves it, and the Host's workspace confinement still applies. The grammar lives in [`src/file-address.ts`](src/file-address.ts); the path helpers stay in [`src/index.ts`](src/index.ts), which re-exports it.
+A resource address is `dsh-resource://<type>/…`, and the type — the URI host — is the resource protocol key (`file`, or one a plugin declares in `ResourceProtocolMap`); any other scheme is a navigation protocol, defined elsewhere. `dsh-resource://file/session/<sessionId>/<path>` names the Session that authorizes the Host read and a workspace-relative or absolute path. Leading slashes remain part of the path: `/etc/hosts` is `dsh-resource://file/session/s//etc/hosts`, a Windows drive is `dsh-resource://file/session/s/C:/x/y.txt`, and UNC is `dsh-resource://file/session/s///server/share/y.txt`. The Host resolves paths and enforces access. The `absolute/<path>` form remains parseable but carries no authorizing Session, so the file provider cannot read it and Preview does not claim it; neither current nor Tab Session is borrowed. The grammar lives in [`src/file-address.ts`](src/file-address.ts); the path helpers stay in [`src/index.ts`](src/index.ts), which re-exports it.
 
-`sessionFileAddress(sessionId, relativePath)` and `absoluteFileAddress(absolutePath)` build one: `\` becomes `/`, a leading `./` or `/` is dropped, and every id and path segment is component-encoded with `:` kept literal, so `#`, `?`, and spaces in a name survive while a drive letter reads as written. `fileAddressFor(sessionId, cwd, path)` chooses the scope for a path as a caller holds it: a relative path, or an absolute path inside `cwd`, becomes `session`-relative; any other absolute path becomes `absolute`. `parseFileAddress(address)` reads one back through `new URL()`: the scheme must be `dsh-resource` and the host exactly `file`; a `session` address yields `{ scope, sessionId, path }` with the workspace-relative path, an `absolute` address yields `{ scope, path }` with the leading `/` restored (`//` for a UNC path) unless the path starts with a drive letter. It returns `undefined` for another type or scheme, an unknown scope, a missing id or path, a non-URL, or a malformed escape — the caller decides whether that is a failure.
+`sessionFileAddress(sessionId, path)` normalizes `\` to `/` and drops leading `./`, but preserves leading `/` characters. Every id and path segment is component-encoded with `:` kept literal. `fileAddressFor(sessionId, cwd, path)` always builds a Session address: paths inside `cwd` become relative; other absolute paths, including when `cwd` is unknown, stay absolute within that Session address. `absoluteFileAddress(absolutePath)` builds only the Session-less form. `parseFileAddress(address)` uses `new URL()` and returns `{ scope, sessionId, path }` for a Session address, preserving its relative or absolute path; the Session-less form returns `{ scope, path }` with its absolute path. Another type or scheme, an unknown scope, a missing id or path, a non-URL, or a malformed escape returns `undefined`.

-`sessionFileAddress(sessionId, relativePath)` 与 `absoluteFileAddress(absolutePath)` 构造地址：`\` 归一为 `/`，去掉前导 `./` 或 `/`，id 与每个路径段做组件编码但 `:` 保持字面，因此名字里的 `#`、`?`、空格都能保留，盘符也照原样可读。`fileAddressFor(sessionId, cwd, path)` 按调用方手里的路径选作用域：相对路径或落在 `cwd` 内的绝对路径成为 `session` 相对地址，其他绝对路径成为 `absolute` 地址。`parseFileAddress(address)` 用 `new URL()` 读回：scheme 必须是 `dsh-resource`、host 必须恰为 `file`；`session` 地址得到 `{ scope, sessionId, path }`（path 为工作区相对路径），`absolute` 地址得到 `{ scope, path }` 并还原前导 `/`（UNC 路径还原为 `//`），以盘符开头者除外。对其他 type 或 scheme、未知作用域、缺 id 或路径、非 URL、或转义格式错误的输入返回 `undefined`，是否算失败由调用方决定。
+`sessionFileAddress(sessionId, path)` 将 `\` 归一为 `/`，去掉前导 `./`，但保留前导 `/` 字符。id 和每个路径段都做组件编码，`:` 保持字面。`fileAddressFor(sessionId, cwd, path)` 始终构造 Session 地址：`cwd` 内的路径转为相对路径；其他绝对路径（包括 `cwd` 未知时）仍作为该 Session 地址内的绝对路径。`absoluteFileAddress(absolutePath)` 只构造不带 Session 的形式。`parseFileAddress(address)` 使用 `new URL()`，为 Session 地址返回 `{ scope, sessionId, path }`，保留其相对或绝对路径；不带 Session 的形式返回 `{ scope, path }`，其中 path 为绝对路径。其他 type 或 scheme、未知作用域、缺 id 或路径、非 URL 或错误转义都返回 `undefined`。

 Preview records its loaded version and the version observed when a read starts. Refresh rereads only that tab, without changing shared metadata or another tab's content. Reads are non-transactional; versions are opaque equality tokens, not ordered timestamps ([resource observation and Preview RPC](../../.agents/notes/implemented/architecture/2026-09-08-document-preview-operations.md)).

Its fixed header shows the Host's absolute path when available, otherwise the requested path, and a dropdown for matching renderers plus plain text. A wrap toggle appears only when the selected renderer declares `wrap: true`; the per-tab preference starts on. Reload stays in this header, not the Sidebar's tab strip. The shared body below owns document scrolling.
 - **Shared loading and view state**, session-scoped and bucketed by tab id. The store holds accumulated pages or complete bytes, read and observed versions, loading/failure state, renderer choice, scroll offset, wrap, and the answered navigation revision. The ordinary inject face calls Remote readers and writes through declared store actions. Reloads and loading-mode changes retire older requests; the tab's abort signal forgets its state.

 HTML runs in a Blob iframe with exactly `sandbox="allow-scripts"`, without `allow-same-origin`; scripts cannot access the parent application's origin or file reader. The renderer loads directly declared relative `.js` classic scripts and `.css` stylesheets through its ordinary inject callback to `remote.workspaceFiles.readRelated`, under the configured limits. Host code resolves the related path; `rpc.ts` decodes the returned bytes. Inside the renderer, base64 is used only to embed the iframe bootstrap payload in script text. A `<base href>` leaves dependency resolution to the browser, as do HTTPS resources. Local module imports, CSS `url()`/`@import`, and dynamic `fetch` do not use Host file access. Read failures, invalid UTF-8, or exceeded limits fail the preview rather than publishing a partial asset package. Replacing or unmounting the document releases its Blob URL.

 Initial reads, additional pages, and HTML/PDF preparation share a loading indicator that respects reduced-motion preferences. Loaded pages stay visible while another page loads. Code previews show source line numbers by default without including them in copied text; plain text uses the same font size and line height as code.

+A tab type registers in two stages, and the shipped guide type goes through exactly the same public path a type from another package does (`ui-sidebar-documentpreview` is the live proof). Both stages sit inside the type's own `ctx.effect`, so the registration lives exactly as long as the plugin that made it.
 
 1. **The type** — `ctx.sidebarRightTabs.register({ id, kind, patterns?, priority?, canOpen?, title, guide? })`, a static declaration with no runtime hook, returning a disposer. `id` is this implementation's identity in the tab system, unique across every registration (a package name is the natural value; the shipped guide is `@deepseek-ai/dsh-client-ui-sidebar-right/guide`): a kind is not unique once an extension may take a builtin's over, so the implementation names itself, and a second registration of an `id` throws. A resource type names `patterns`, globs over `dsh-resource://` addresses: one containing `:` matches the whole address (`dsh-resource://file/**`); one without matches the URI's path at any depth, ignoring case (`*.md`), and an address that is not a URI matches no such pattern. A page type — the guide, a file tree — names none and is opened by kind. `canOpen(address)` vetoes a match. `title(address)` is the tab chip's text, captured when the tab opens. `guide` lists entry boxes for the guide page; picking one opens the contributing type as a page. A `kind` carries at most one `builtin` and one `extension` registration (the extension is in force; the builtin resumes when it leaves); any other collision on a kind throws. The `id` is also the key the type's body and title register under, so an extension and the builtin it takes over hold distinct cells and the seat renders the one in force.
 2. **The body** — `ctx.slots.register({ name: 'sidebar.right.pane.tab', key: definition.id }, Body)` reads `{ sidebar, panel, tab }` through the framework-injected `useTabInfo()`. `sidebar` supplies expansion and fullscreen information; `panel.id` identifies its pane; `tab` contains the record fields, `visible`, `navigation`, `signal`, and `actions`. These are not parallel owner props; the type's own store still uses `useStore`/`actions`. Optional title registrations and guide replacements share this hook; an absent title registration uses the text captured at open time.

+tab 类型分两阶段注册，随包发布的引导类型走的正是别的包的类型走的同一条公开路径（`ui-sidebar-documentpreview` 是活的证明）。两个阶段都在类型自己的 `ctx.effect` 里，因此注册与创建它的插件同生共死。
 
 1. **类型**——`ctx.sidebarRightTabs.register({ id, kind, patterns?, priority?, canOpen?, title, guide? })`，一份没有运行时钩子的静态声明，返回 disposer。`id` 是这个实现在 tab 系统里的身份，在全部注册中唯一（包名是天然取值；随包引导页是 `@deepseek-ai/dsh-client-ui-sidebar-right/guide`）：一旦 extension 可以接管 builtin 的 kind，kind 就不再唯一，所以实现要自己命名，同一 `id` 的第二次注册会 throw。资源类型给出 `patterns`，即作用于 `dsh-resource://` 地址的 glob：含 `:` 的匹配整个地址（`dsh-resource://file/**`）；不含的匹配 URI 路径的任意深度且忽略大小写（`*.md`），不是 URI 的地址不匹配任何这类模式。页类型——引导页、文件树——不给出模式，按 kind 打开。`canOpen(address)` 否决一次命中。`title(address)` 是 tab chip 的文字，在 tab 打开时捕获。`guide` 列出引导页的入口框；选中一个即把贡献它的类型作为页打开。一个 `kind` 最多承载一份 `builtin` 与一份 `extension` 注册（extension 生效；它离开后 builtin 恢复）；kind 上的其它任何撞名都 throw。`id` 同时也是该类型正文与标题注册时用的 key，因此 extension 与它接管的 builtin 各占一个格位，席位渲染生效的那个。
 2. **正文**——`ctx.slots.register({ name: 'sidebar.right.pane.tab', key: definition.id }, Body)` 通过框架注入的 `useTabInfo()` 读取 `{ sidebar, panel, tab }`。`sidebar` 提供开合与全屏信息，`panel.id` 命名所在格，`tab` 包含原记录字段、`visible`、`navigation`、`signal` 和 `actions`。这些字段不再作为平铺owner props传入；类型自己的store仍使用 `useStore`/`actions`。可选标题注册及引导替换共享该hook；未注册标题时使用打开时保存的文本。

 Document Preview separates resource observation from content reads. The [resource model](2026-09-05-client-resource-model.md) shares observations by address alone: `source(address)`, `pin(address, signal)`, and provider `open(address, { signal })` carry no consuming Session. Providers return `AsyncIterable<RemoteResult<ResourceProtocolMap[P]>>`; `useResource` exposes only `{ status, value, failure }`. Holds start and stop observation, not the underlying file or Session. Content reads use ordinary injected Preview callbacks.
 
-[Workspace Files](../../../../packages/api/workspace-files/README.md) retains Host line reads, byte windows, bounded complete reads, and bounded reads relative to another file's directory. Its Client `file` provider observes only `stat` and `changes`, with `ResourceProtocolMap.file` directly naming `WorkspaceFileStat`. The Host continues to resolve and confine every path under the [file-service decision](2026-09-05-workspace-files-service.md).
+[Workspace Files](../../../../packages/api/workspace-files/README.md) retains Host line reads, byte windows, bounded complete reads, and bounded reads relative to another file's directory. Its Client `file` provider observes only `stat` and `changes`, with `ResourceProtocolMap.file` directly naming `WorkspaceFileStat`. The Host resolves every path through the Session filesystem; file reads inherit that backend's read authority, while directory listing and change observation stay workspace-scoped.
 
 Readable files use `dsh-resource://file/session/<sessionId>/<path>`. The path may be workspace-relative or absolute; an encoded absolute path retains its leading slash. `fileAddressFor` always emits this Session-address form. The provider and Preview RPC take the Session only from that address, never from the current selection, first holder, or owning tab. A Session-less `absolute` URI cannot be read; the provider reports `workspace-file/unknown-workspace`. Session authorization is a file-protocol rule, not an additional Resource identity.

The child receives accumulated text or complete native bytes, the original resource address, and the standard `useResource` and `useTabInfo` hooks.

Published buffers are borrowed read-only and never persist into layout or Session JSON. PDF.js runs in an owned Worker with version-matched bundled font and decoder data, and copies input before transfer to preserve Preview's retained buffer. HTML runs in a Blob iframe with `sandbox="allow-scripts"`, without same-origin, popup, form, download, or top-navigation privileges. The browser retains its normal external-network rules. Bounded static local JS/CSS reads stay in the parent; the opaque frame creates its own asset Blobs, because it cannot load parent-origin Blobs. Replacing the document replaces the browsing context and revokes its root Blob.

 ## Consequences
 
-Renderers can be replaced without changing the tab or file protocol. Full-file formats pay bounded whole-file memory and PDF adds bundled Worker/font/decoder bytes. Format selection and view state are page-local, not durable Session data. Preview owns RPC cancellation and native buffers independently of metadata observation. A tab retains its read version and the observation version captured at read start; refreshing it neither discards another tab's content nor clears its change notice. File reads remain non-transactional, and opaque versions are compared for equality, not ordering. The [recorded browser scenario](../../../../apps/web/tests/document-preview.e2e.ts) exercises the shared toolbar, incremental text, isolated HTML dependencies, and PDF Worker rendering with retained page state.

 可读取的文件使用 `dsh-resource://file/session/<sessionId>/<path>`。路径可以相对工作区，也可以是绝对路径；编码后的绝对路径保留前导斜杠。`fileAddressFor` 始终生成这种 Session 地址。提供方与 Preview RPC 只从该地址取 Session，不取当前选择、首个持有者或 tab 所属 Session。不带 Session 的 `absolute` URI 无法读取；提供方报告 `workspace-file/unknown-workspace`。Session 授权是文件协议规则，不是额外的 Resource 身份。

Every call passes the same four gates — the path is inside the workspace root, symlinks are refused, page, window, and entry caps hold, `read`'s text is UTF-8 — and fails with a `workspace-file/*` error code otherwise ([failures](../../packages/api/workspace-files/README.md)).
+The Host `ctx.workspaceFiles` service and generated `workspaceFiles` Remote namespace read files allowed by the Session filesystem backend: `stat(path)` returns `{ absolutePath, version, bytes? }`; `read(path, { offset?, limit? })` returns one page of lines (`offset` 1-based, `limit` capped by the configured page size) as `{ …stat, offset, text, eof }`; `readBytes(path, { offset?, length? })` returns one raw byte window (`offset` 0-based, `length` capped by the configured byte limit) as base64 `{ …stat, offset, data, eof }` with no text decoding. `list(path)` remains inside the workspace root and returns a directory's direct children (`name`, `type: 'file' | 'directory' | 'other'`, `size?`) cut to the configured cap with `truncated` set. `changes()` likewise remains workspace-scoped and yields `{ kind: 'ready' }` once subscribed, then `{ kind: 'change', change }` frames whose payload is `{ absolutePath, version }` or `{ absolutePath, absent: true }` ([README](../../packages/api/workspace-files/README.md#use-this-package)). File operations reject final symlinks and enforce transfer caps; `read` additionally requires UTF-8 text. Failures use `workspace-file/*` codes ([failures](../../packages/api/workspace-files/README.md)).
 
 [`dsh-api-workspace-files`](../../packages/api/workspace-files/README.md) registers the `file` provider, with `ResourceProtocolMap.file` directly naming `WorkspaceFileStat`. A Session address carries the authorizing Session and a relative or absolute path, passed unchanged to the Host for resolution. The provider waits for Host `ready` before stat and filters changes by `stat.absolutePath`. Bare `absolute` addresses have no authorizing Session and fail with `workspace-file/unknown-workspace`, without borrowing current or Tab Session. Any UI, including Global components, shares the observation for the same complete address. Preview's ordinary Remote callbacks use the Session in that address; Host `readAll` and `readRelated` remain, and Preview's `rpc.ts` decodes byte results.

 ## Summary
 
-Use this package to browse and inspect files within a Session's workspace from the web client. It reads UTF-8 text one page of lines at a time, reads raw bytes in bounded windows or complete files, resolves related files from a base file's directory, reports file versions and sizes, lists direct directory children, and streams changes caused by Agent file operations. Every operation stays within the workspace root selected for the addressed Session, independent of the filesystem backend's working directory. Client components can also follow live file metadata and build the Sidebar file tree through the shared Remote API.
+Use this package to preview files readable through a Session's filesystem from the web client. It reads UTF-8 text by page, reads bounded byte windows or complete files, resolves related files from a base file's directory, and reports file metadata. File reads may target paths outside the workspace; directory listing and Agent-write change observation remain workspace-scoped. The service exposes no mutation operation.

 ### Addressing and paths
 
-`read`, `stat`, and `list` accept a workspace path that is absolute or relative to the Session's workspace root. Two path vocabularies leave the service, and each method uses exactly one: `read`, `stat`, and `changes` report a file as its absolute path in the filesystem's execution world, symlinks resolved (`WorkspaceFileStat.absolutePath`, `WorkspaceFileChange.absolutePath`), because their consumer is the Client resource system, which follows changes by that path; `list` reports the listed directory as a workspace path relative to the root — empty for the root itself — because its consumer is a tree rooted there, and a child's path is that value joined with the entry name by `/`. `readRelated` resolves a relative filesystem path from the base file's directory, not a URL or absolute path; both files pass Host access checks.
+`read`, `readBytes`, `readAll`, `readRelated`, and `stat` accept an absolute path or one relative to the Session's workspace root. The composed filesystem decides whether the path is readable; the service does not impose workspace containment on file reads. `readRelated` resolves a relative filesystem path from the base file's directory, including when either file is outside the workspace. These methods report the file's absolute path in the filesystem's execution world. `list` remains workspace-scoped and reports the listed directory relative to that root. `changes` likewise reports only Agent observations inside the workspace root.
 
 ### Pages
 
@@ -49,9 +49,9 @@ Mount the package beside `dsh-fs`, `dsh-sandbox-policy`, and the Typert Gateway;
 
 `read` pages by lines and never by bytes; a byte window is `readBytes`. `range.offset` is the 0-based first byte and defaults to 0; `range.length` is the largest number of bytes in the window and defaults to `maxBytes`, which it may not exceed — a longer window fails with `too-large` instead of arriving shortened, and an offset or length that is not an integer in range is a `gateway/bad-request`. The window comes back as base64 `data`, shorter than `length` at the end of the file and empty at or past it; `eof` is true when the window includes the file's last byte. Nothing is decoded and nothing is refused as binary, so an image or a NUL-laden file reads where `read` fails with `not-text`. The same `version` and `bytes` ride along as on a page.
 
-### The four gates
+### File-read and directory checks
 
-Every read, stat, and listing passes four gates in this order. First, `lstat` inspects the path itself before anything follows it: a symlink, wherever it points, fails `read` and `stat` with `not-regular-file` and `list` with `not-directory`, each carrying the entry's `kind`. Second, containment: the path resolves to a target and `ctx.fs.contains(root, target)` decides, so a `..` traversal or an absolute path outside the root fails with `outside-workspace` — never a string-prefix comparison, which cannot see a realpath that leaves the root. Third, the caps: a page whose text exceeds `maxBytes` fails with `too-large` instead of arriving shortened — paged reads have no total file cap, while complete reads use `maxFileBytes` — while `maxEntries` cuts a listing and sets `truncated`. Fourth, text: content that is not UTF-8 up to the end of the page, or a page that carries a NUL byte, fails with `not-text`; bytes past the page are not inspected. A missing path fails with `not-found`; an empty path is a `gateway/bad-request`.
+Every operation first uses `lstat` to reject a missing path, a final symlink, or the wrong file kind. File operations then resolve and read through the composed filesystem without an additional workspace-containment check. `list` alone requires the resolved directory to remain inside the workspace root. The configured page, window, complete-file, and listing caps still apply. Text pages additionally reject invalid UTF-8 and NUL bytes; byte reads do not decode content. An empty path is a `gateway/bad-request`.

 ### Design concept
 
-Reads through `ctx.fs` are deliberately unconfined — the sandboxing backend fences writes and edits only — so every constraint here is the service's own. A page is cut from `streamText`, which decodes and rejects non-UTF-8 chunk by chunk: the cutter counts lines before the window without keeping them, admits each in-window segment against the byte cap before buffering it, and returns at the first character past the window, so neither a huge file nor one giant line can hold more than a page in memory; the NUL scan then runs on the page. One `stat` before the stream names the version and size the page reports. The path gate runs before containment on purpose: `lstat` is path-shaped and sees the link, while `resolve` follows it; the price is that an entry outside the root reports its own kind before its position.
+Reads through `ctx.fs` use the backend's read authority; the sandboxing backend fences writes and edits, not reads. The service adds regular-file checks and bounded transfer, while workspace containment belongs only to directory listing and change observation.

 The Web client needs to look at files inside a session's workspace from a browser that may not be on the Host machine: a file the agent produced, the path a `read` tool row names, later a file tree and previews of files that are neither small nor text. The one endpoint that read a workspace file over the wire lived on the Session Controller as `workspace-file.ts`, beside session lifecycle it had nothing to do with. It returned a whole file under one total byte cap, so a large log could not be looked at even in part and a binary could not be looked at at all; it had no `stat`, no listing, and no change signal, so a preview could not learn that the agent had rewritten the file without re-reading it; and its result named the file by a Host `url`, a spelling nothing on the Client used as an address.
 
-Two constraints frame any answer. Reads through `ctx.fs` are deliberately unconfined — the sandboxing backend fences writes and edits only and says so — so a web-facing read endpoint must own every fence itself, and the fences must survive a symlink that leaves the workspace, which a string-prefix test cannot see. And `dsh-fs` exposed one raw-byte read, `readBytes(target, signal, maxBytes)`, which refuses any file longer than its cap: correct for an image the model ingests whole, useless for one window of a large file.
+Two constraints frame the service. File reads through `ctx.fs` use the Session's composed filesystem backend, whose read authority may extend outside the workspace, while directory-tree and change-feed consumers are workspace-rooted. The service preserves the backend's read decisions for regular files while enforcing file-kind and bounded-buffer checks; `list` and `changes` retain workspace containment. And `dsh-fs` exposed one raw-byte read, `readBytes(target, signal, maxBytes)`, which refuses any file longer than its cap: correct for an image the model ingests whole, useless for one window of a large file.
 
 ## Decision
 
-`packages/api/workspace-files` (`@deepseek-ai/dsh-api-workspace-files`) owns the Host `ctx.workspaceFiles` service, the `workspaceFiles` Remote namespace, and the Client `file` provider that turns `stat` and `changes` into live metadata for the [resource model](2026-09-05-client-resource-model.md); [dual-face packaging](2026-09-07-workspace-files-dual-face-package.md) governs their package organization. Every method confines itself to the workspace root the sandbox policy resolves for the addressed session, names files by their absolute path in the filesystem's execution world, and bounds content by page, byte window, or complete-file cap. The byte window rides on a new `dsh-fs` seam, `FileSystem.readByteRange`, implemented by every provider. The Session Controller carries no workspace-file code.
+`packages/api/workspace-files` (`@deepseek-ai/dsh-api-workspace-files`) owns the Host `ctx.workspaceFiles` service, the `workspaceFiles` Remote namespace, and the Client `file` provider that turns `stat` and `changes` into live metadata for the [resource model](2026-09-05-client-resource-model.md); [dual-face packaging](2026-09-07-workspace-files-dual-face-package.md) governs their package organization. File methods resolve relative paths from the workspace root but inherit the Session filesystem backend's read authority; `list` and `changes` remain workspace-scoped. The [workspace file read authority](2026-09-09-workspace-file-read-authority.md) owns this split and its security consequences. Results name files by their absolute path in the filesystem's execution world, and content is bounded by page, byte window, or complete-file cap. The byte window rides on a new `dsh-fs` seam, `FileSystem.readByteRange`, implemented by every provider. The Session Controller carries no workspace-file code.

 - **`read`** returns one window of lines, `WorkspaceFileText = WorkspaceFileStat & { offset, text, lines, eof }`; `lines` counts the page's lines, so a page holding one empty line (`text: ''`, `lines: 1`) and a page past the end (`lines: 0`) read differently. `range.offset` is the 1-based first line and defaults to 1; `range.limit` is the largest number of lines and defaults to `maxLines`, which it may not exceed. Lines end at `\n` and a final `\n` terminates the last line rather than opening an empty one; `text` joins the page's lines with `\n` and carries no terminator; `eof` is true when the page includes the last line, and an offset past the end returns an empty page with `eof` true. The pager walks `streamText`, counts the lines before the window without keeping them, admits each in-window segment against `maxBytes` before buffering it, and returns at the first character past the window, so a file of any size costs one page of memory. The `version` and `bytes` on a page are the stat's, taken before the stream.
 - **`readBytes`** returns one window of raw bytes, `WorkspaceFileBytes = WorkspaceFileStat & { offset, data, eof }`. `range.offset` is the 0-based first byte and defaults to 0; `range.length` is the largest byte count and defaults to `maxBytes`, which it may not exceed. `data` is base64, shorter than `length` where the file ends and empty at or past it; `eof` is true when the window includes the last byte.

 `version` is an opaque string a consumer compares for equality and never parses: the local backend derives it from device, inode, size, and nanosecond mtime and ctime, so a rewrite that leaves the content identical still changes it. `offset` means a line on `read` and a byte on `readBytes`; the two units never mix, and `eof` on either means the window reached the file's end.
 
-### The four gates
+### File checks and workspace containment
 
-Every `read`, `readBytes`, `readAll`, `readRelated`, `stat`, and `list` passes four gates in order, and the constraints are the service's own because the filesystem does not confine reads. The path is inspected before containment is decided, so a caller learns whether an outside path exists and what kind it is before `outside-workspace` refuses it; that is accepted because the caller is the Session's own owner, who can already read the Host through the Agent.
+`read`, `readBytes`, `readAll`, `readRelated`, and `stat` share regular-file checks and then rely on the filesystem backend's read authority. `list` shares path inspection but also checks workspace containment, while `changes` filters observations to the workspace root. The service applies the following checks:
 
 1. **The path itself.** `lstat` inspects the path before anything follows it: a missing path is `not-found`, and a symlink — wherever it points, including back inside the workspace — is `not-regular-file` (kind `symlink`) for the file methods and `not-directory` for `list`. An empty path is a `gateway/bad-request`.
-2. **Containment.** The path resolves to a target and `ctx.fs.contains(root, target)` decides, where `root` is `sandboxPolicy.resolve({ session }).workspaceRoot` resolved the same way (the session's cwd, falling back to the policy's configured root). A `..` traversal or an absolute path outside the root is `outside-workspace`. A string-prefix comparison is never used: `resolve` realpaths, so a prefix test cannot see a link that leaves the root.
+2. **Workspace containment for `list`.** The directory resolves to a target and `ctx.fs.contains(root, target)` decides, where `root` is `sandboxPolicy.resolve({ session }).workspaceRoot` resolved the same way. A `..` traversal or an absolute directory outside the root is `outside-workspace`. `changes` applies the same backend containment predicate to observed targets.
 3. **The caps.** A page or window above `maxBytes`, or a `read` asking for more than `maxLines`, is refused, never shortened, because a silently cut page reads as the whole page; a listing above `maxEntries` is cut and says so. Complete and related-file reads are refused above `maxFileBytes`.
 4. **Text.** For `read` only: content that is not UTF-8 up to the end of the page, a NUL byte in the backend's 8 KiB opening sample, or a NUL byte anywhere in the page is `not-text`; bytes past the page are not inspected.
 
-After the gates the file methods `stat` the target once more, because the file may have gone or changed kind between the inspection and the read: a vanished file is `not-found` and a replaced one `not-regular-file` with the new kind. The gate order has one visible consequence: an entry outside the root whose type already disqualifies it reports its kind, not its position.

 - **The value is metadata**, `WorkspaceFileStat { absolutePath, version, bytes? }`; content never rides the stream because content can be arbitrarily large and a stream is for pushing change, not payload. A consumer reads pages with `read` (or windows with `readBytes`) and compares versions to know when they are stale; freshness and refresh belong to each consumer, not the shared observation.
-- **The address names the file; its scope selects the Session.** A `session` address's relative or absolute path reaches the Host unchanged for resolution and containment against that Session's workspace root; Client cwd is not a prerequisite. An `absolute` address has no Session and fails with `workspace-file/unknown-workspace`; no current or tab Session is borrowed. Unsupported grammar yields `workspace-file/unsupported-address`. These two Client errors end the stream.
+- **The address names the file; its scope selects the Session.** A `session` address's relative or absolute path reaches the Host unchanged; the workspace root supplies the base for a relative path, and the Session filesystem backend decides read access. Client cwd is not a prerequisite. An `absolute` address has no Session and fails with `workspace-file/unknown-workspace`; no current or tab Session is borrowed. Unsupported grammar yields `workspace-file/unsupported-address`. These two Client errors end the stream.
 - **The frames.** The first frame is a `stat` or its failure as an `ok: false` frame; the provider throws and catches nothing, because the Remote face never rejects and a throw inside a provider stream is a programming error left to surface. A Host write carrying a version the value does not hold yields that version with the byte count kept and no stat; a frame carrying the held version is dropped. A reported disappearance stats again — still there is fresh metadata, gone is a `not-found` frame with the previous value left for display. The follow is on the address, not the file: after a failed stat the stream continues, so the agent creating the file brings the resource live. Aborting the signal ends the stream silently.
 - **One `changes` subscription per Session.** The first follower opens `remote.$stream`, the last release disposes it, and successor streams and plugin teardown await pending closes. The Client starts its first `stat` only after accepting Host `ready`; sending a local WebSocket request is not Host acknowledgement. A follower registers by address, queues changes before its path is known, then filters queued and live frames by the successful stat's `absolutePath`, normalizing backslashes to slashes. Any Session write can trigger a re-stat before the first successful binding. Gateway supervision reconnects carrier loss; Host end or terminal failure ends followers and retains their last metadata until reopened.
 - **Navigation parameters.** `SidebarRightResourceParamsMap.file` is `WorkspaceFileParams { line?: number }`, a 1-based line to reveal. A line travels as a navigation parameter and not as part of the address, because the file is one piece of content whether it opens at the top or at line 400.

 ## Alternatives considered
 
-**Keeping the workspace file endpoint on the Session Controller.** The first form: one `read` under a total byte cap, registered as a sub-plugin of the Session Controller because that is where the wire entry already was. Rejected because a Workspace File service is its own capability — reading, statting, listing, and observing files inside a workspace root — and everything that queries workspace files belongs to it, while the Session Controller's concern is session lifecycle. The move also let the service grow to five methods without the Controller's file gaining a second purpose.

 **A dual-face package with reverse UI dependencies.** The split-package choice followed two project-reference cycles after `api/remotes` referenced the Client leaf: the resource model imported Remote assembly for result types, and the file provider imported Sidebar UI for its parameter map. TypeScript rejected these cycles with `TS6202`. [dual-face packaging](2026-09-07-workspace-files-dual-face-package.md) supersedes that split: result types come directly from the protocol package, and Sidebar parameter registration belongs to the text preview; both root aggregates retain explicit compiler entries.
 
 **Serving workspace files over HTTP.** Already rejected by [workspace file links](../feature/2026-07-31-web-workspace-file-links.md) on origin grounds and not revisited: `read` and `readBytes` carry plain text and base64 over the authenticated Remote carrier, so no document is served, no URL is minted, and no origin question arises.
 
-**Log-reachable authorization for the read.** The one precedent that sends file content over the wire, command attachments, authorizes only files that appear in the session log. Enough for produced files, but a typed path or a directory tree could never open. Path containment inside the workspace root was chosen, with the endpoint owning the constraints the filesystem's unconfined reads do not, and containment decided by `fs.contains` on resolved targets so a symlink cannot escape it.
+**Log-reachable or workspace-contained authorization for file reads.** The one precedent that sends file content over the wire, command attachments, authorizes only files that appear in the session log. That excludes typed paths, while workspace containment excludes readable files elsewhere on the Session backend. The [workspace file read authority](2026-09-09-workspace-file-read-authority.md) instead makes the backend's read decision authoritative and keeps containment only for workspace-shaped operations.
 
 **Whole-file read and slice for the byte window.** The interim form of `readBytes` read the file from its start to the window's end through `readBytes(target, signal, offset + length)` and sliced. It cannot read a window of a file longer than that end — the seam refuses such a file as too large — so no window could ever report `eof: false`, which contradicts the reason the method exists. Rejected in favour of the `readByteRange` seam, whose bound is the window.

Abstract, with every provider and double implementing it.
 
-**String-prefix containment.** Comparing resolved path strings against the root is simpler than `fs.contains`, but `resolve` realpaths, so a symlink that leaves the root resolves to a path outside it while a prefix test on the unresolved spelling passes; and a prefix test on the resolved spelling still needs the backend's notion of "same file".

 - Every filesystem provider now offers a windowed raw read. `fs-e2b` pays for it by transferring the skipped prefix, since its SDK cannot seek; `fs-local` seeks.
 - Paths on the wire are canonical: `absolutePath` and change frames spell a file with symlinks resolved. A follower binds to successful `stat.absolutePath`, so another spelling of the same file — a workspace root reached through a symlink — uses that canonical change key.
 - Change frames report the agent's own operations only. A file edited by the user's editor, a shell, or a subprocess raises no frame; an agent merely reading a file that something else changed does raise one, because the read observes a new version.

-### 四道关
+### 文件检查与工作区包含
 
-每次 `read`、`readBytes`、`readAll`、`readRelated`、`stat` 与 `list` 依次过四道关，而这些约束是服务自己的，因为文件系统并不限制读取。路径先被检视再判定是否在工作区内，因此调用方在 `outside-workspace` 拒绝之前就能得知工作区外的路径是否存在、是何种类；这一点被接受，因为调用方就是 Session 的所有者，本来就能经 Agent 读 Host。
+`read`、`readBytes`、`readAll`、`readRelated` 与 `stat` 共享普通文件检查，之后依赖文件系统后端的读取权限。`list` 共享路径检查，但还会检查工作区包含关系；`changes` 则把观察过滤到工作区根内。服务执行以下检查：
 
 1. **路径本身。** `lstat` 在跟随任何东西之前检查路径：缺失路径为 `not-found`；符号链接——不论指向哪里，包括指回工作区内——对文件方法为 `not-regular-file`（kind 为 `symlink`），对 `list` 为 `not-directory`。空路径是 `gateway/bad-request`。
-2. **包含关系。** 路径解析为目标，由 `ctx.fs.contains(root, target)` 判定，其中 `root` 是以同样方式解析的 `sandboxPolicy.resolve({ session }).workspaceRoot`（会话 cwd，退而取策略配置的根）。`..` 爬出或根外绝对路径为 `outside-workspace`。从不使用字符串前缀比较：`resolve` 会取 realpath，前缀测试看不见离开根的链接。
+2. **`list` 的工作区包含。** 目录解析为目标，由 `ctx.fs.contains(root, target)` 判定，其中 `root` 是以同样方式解析的 `sandboxPolicy.resolve({ session }).workspaceRoot`。`..` 爬出或根外绝对目录为 `outside-workspace`。`changes` 对观察到的目标使用相同的后端包含判定。
 3. **上限。** 超过 `maxBytes` 的页或窗口，或 `read` 索要超过 `maxLines` 的行数，一律拒绝、绝不截短，因为悄悄截短的页读起来就像整页；超过 `maxEntries` 的列表被截断并如实报告。全文及关联文件读取超过 `maxFileBytes` 时被拒绝。
 4. **文本。** 仅限 `read`：到页末为止不是 UTF-8 的内容、后端 8 KiB 开头样本里的 NUL 字节，或页内任何位置的 NUL 字节，都是 `not-text`；页之后的字节不检查。
 
-过关之后文件方法再对目标 `stat` 一次，因为在检查与读取之间文件可能已消失或换了种类：消失者为 `not-found`，被替换者为带新种类的 `not-regular-file`。关的顺序有一个可见后果：根外条目若类型本身已不合格，报告的是其种类而不是其位置。

+
+## Problem
+
+Workspace Files serves both file content and workspace navigation. Applying workspace containment to every operation creates a second read policy above the Session filesystem backend and prevents a user from previewing paths that the same Session can read outside its workspace. HTML preview also needs direct relative JavaScript and stylesheet files, including `..` paths, while its script-enabled document can use the browser network.
+
+## Decision
+
+`read`, `readBytes`, `readAll`, `readRelated`, and `stat` inherit the addressed Session filesystem backend's read authority. The workspace root is the base for relative input paths, not a read boundary; absolute paths and relative paths that leave the workspace are readable when the backend allows them. The service still requires regular files, refuses symlinks, and applies its text and byte caps.
+
+`list` and `changes` remain workspace-scoped because they expose workspace navigation and observation rather than a named file read. `list` rejects a directory outside the root, and `changes` filters observations through the backend's workspace-containment predicate.
+
+`readRelated` resolves a relative path from the base file's directory. A `..` path may therefore read JavaScript or CSS outside the workspace when the Session backend permits it. Document Preview packages bounded, statically declared local scripts and stylesheets into an HTML Blob iframe with `sandbox="allow-scripts"`; the opaque origin blocks parent access, but the browser retains normal network access. This exposure is an intentional security trade-off for rendering static generated HTML.
+
+The [Workspace Files service](2026-09-05-workspace-files-service.md) owns paging, file checks, listing, and observation. [Document Preview](2026-09-08-document-preview-operations.md) owns which related files are packaged and the iframe sandbox.
+
+## Alternatives considered
+
+**Contain every operation within the workspace.** This gives previews a narrower policy than the Session filesystem backend, blocks explicitly addressed readable files, and prevents HTML beside external assets from rendering. Workspace containment remains where the operation itself represents the workspace.
+
+**Permit outside reads but block all iframe networking.** A stricter CSP would reduce exfiltration risk, but it would also reject external assets and network behavior intentionally retained for the static-HTML preview. The opaque sandbox protects the parent application; it does not promise network isolation.
+
+## Consequences
+
+Any caller holding a valid Session file address can receive bytes from every regular file that the Session filesystem backend permits it to read, including files outside the workspace. A previewed HTML document can execute packaged local JavaScript and make network requests. Outside files do not produce `changes` frames, so their previews require explicit refresh to observe updates.

+# Agent Note: 工作区文件读取权限
+
+Status: implemented
+
+[English](2026-09-09-workspace-file-read-authority.md) | 中文
+
+## Problem
+
+Workspace Files 同时提供文件内容与工作区导航。对所有操作应用工作区包含限制，会在 Session 文件系统后端之上形成第二套读取策略，并阻止用户预览同一 Session 在工作区外可读的路径。HTML 预览还需要直接读取相对 JavaScript 与样式表文件，包括含 `..` 的路径，而启用脚本的文档可以使用浏览器网络。
+
+## Decision
+
+`read`、`readBytes`、`readAll`、`readRelated` 与 `stat` 继承被寻址 Session 的文件系统后端读取权限。工作区根是输入相对路径的基准，而不是读取边界；只要后端允许，就可以读取绝对路径和离开工作区的相对路径。服务仍要求普通文件、拒绝符号链接，并应用文本和字节上限。
+
+`list` 与 `changes` 仍限于工作区，因为它们暴露工作区导航和观察，而不是读取一个具名文件。`list` 拒绝根外目录，`changes` 通过后端的工作区包含判定过滤观察。
+
+`readRelated` 从基准文件所在目录解析相对路径。因此，只要 Session 后端允许，`..` 路径就可以读取工作区外的 JavaScript 或 CSS。Document Preview 把有界、静态声明的本地脚本与样式表打包进带 `sandbox="allow-scripts"` 的 HTML Blob iframe；不透明源阻止访问父应用，但浏览器保留正常网络访问。这种暴露是为渲染静态生成 HTML 而有意接受的安全取舍。
+
+[Workspace Files 服务](2026-09-05-workspace-files-service.zh.md)负责分页、文件检查、列举和观察。[Document Preview](2026-09-08-document-preview-operations.zh.md)负责选择要打包的关联文件及 iframe sandbox。
+
+## Alternatives considered
+
+**把所有操作限制在工作区内。** 这会让预览采用比 Session 文件系统后端更窄的策略，阻止读取明确寻址的可读文件，并使位于外部资源旁的 HTML 无法渲染。操作本身代表工作区时，仍保留工作区包含限制。
+
+**允许根外读取，但阻断 iframe 的全部网络。** 更严格的 CSP 可以降低数据外传风险，但也会拒绝静态 HTML 预览有意保留的外部资源与网络行为。不透明 sandbox 保护父应用，但不承诺网络隔离。
+
+## Consequences
+
+持有有效 Session 文件地址的调用方可以接收 Session 文件系统后端允许读取的每个普通文件的字节，包括工作区外文件。预览的 HTML 文档可以执行已打包的本地 JavaScript，并发起网络请求。工作区外文件不会产生 `changes` 帧，因此其预览需要显式刷新才能观察更新。

Its registration is `{ id: '@deepseek-ai/dsh-client-ui-sidebar-textpreview', kind: 'text', patterns: ['dsh-resource://file/**'], priority: 'fallback', title: basenameOf }`. The pattern contains `:` and so matches the whole address; `fallback` is the lowest band, so a type at `extension` or `builtin` with a narrower pattern (`*.png`, say) takes those addresses and everything else lands here, while the text type stays in the candidate list for any file. The `id` is the package name and doubles as the `key` of the body seat, so an extension that takes the `text` kind over cannot make the seat pick up this body by mistake. The title is the address's decoded last segment: the whole address stays the content identity — two files with one name in different directories, or one path under two sessions, are two tabs — and only the chip text is shortened.

Its registration is `{ id: '@deepseek-ai/dsh-client-ui-sidebar-documentpreview', kind: 'text', patterns: ['dsh-resource://file/**'], priority: 'fallback', canOpen, title: basenameOf }`. `canOpen` accepts only addresses whose parsed scope is `session`.

 A tab's address is `dsh-resource://file/session/<sessionId>/<path relative to that session's workspace root>` or `dsh-resource://file/absolute/<absolute path>` ([Workspace Files](../architecture/2026-09-05-workspace-files-service.md) owns the grammar and the `fileAddressFor` / `parseFileAddress` helpers in `dsh-util-workspace-path`). The preview never splits the string itself: `hostFileOf` in `rpc.ts` calls `parseFileAddress` and yields the `{ sessionId, path }` the endpoint takes — a `session` address reads under the session it names with the relative path the Host resolves, an `absolute` address reads under the session the slot was mounted for with the absolute path — and a malformed address throws, a programming error, because the registry routes every `file` address to this type and a caller building one is expected to use the helper.

 A resource address is `dsh-resource://<type>/…`, and the type — the URI host — is the resource protocol key (`file`, or one a plugin declares in `ResourceProtocolMap`); any other scheme is a navigation protocol, defined elsewhere. `dsh-resource://file/session/<sessionId>/<path>` names the Session that authorizes the Host read and a workspace-relative or absolute path. Leading slashes remain part of the path: `/etc/hosts` is `dsh-resource://file/session/s//etc/hosts`, a Windows drive is `dsh-resource://file/session/s/C:/x/y.txt`, and UNC is `dsh-resource://file/session/s///server/share/y.txt`. The Host resolves paths and enforces access. The `absolute/<path>` form remains parseable but carries no authorizing Session, so the file provider cannot read it and Preview does not claim it; neither current nor Tab Session is borrowed. The grammar lives in [`src/file-address.ts`](src/file-address.ts); the path helpers stay in [`src/index.ts`](src/index.ts), which re-exports it.

 ### The text preview
 
+The [Document Preview decision](../architecture/2026-09-08-document-preview-operations.md) supersedes this section's renderer, loading, and resource-observation details. The fallback tab registration, paged source navigation, and body-owned controls remain in force.
+
 `text` is the fallback viewer for Session-scoped files. Its registration is `{ id: '@deepseek-ai/dsh-client-ui-sidebar-documentpreview', kind: 'text', patterns: ['dsh-resource://file/**'], priority: 'fallback', canOpen, title: basenameOf }`. `canOpen` accepts only addresses whose parsed scope is `session`. The pattern contains `:` and so matches the whole address; `fallback` is the lowest band, so a type at `extension` or `builtin` with a narrower pattern (`*.png`, say) takes those addresses and everything else lands here, while the text type stays in the candidate list for any file. The `id` is the package name and doubles as the `key` of the body seat, so an extension that takes the `text` kind over cannot make the seat pick up this body by mistake. The title is the address's decoded last segment: the whole address stays the content identity — two files with one name in different directories, or one path under two sessions, are two tabs — and only the chip text is shortened.
 
 A tab's address is `dsh-resource://file/session/<sessionId>/<path relative to that session's workspace root>` or `dsh-resource://file/absolute/<absolute path>` ([Workspace Files](../architecture/2026-09-05-workspace-files-service.md) owns the grammar and the `fileAddressFor` / `parseFileAddress` helpers in `dsh-util-workspace-path`). The preview never splits the string itself: `hostFileOf` in `rpc.ts` calls `parseFileAddress` and yields the `{ sessionId, path }` the endpoint takes — a `session` address reads under the session it names with the relative path the Host resolves, an `absolute` address reads under the session the slot was mounted for with the absolute path — and a malformed address throws, a programming error, because the registry routes every `file` address to this type and a caller building one is expected to use the helper.

 A changed file is announced, not applied. When the `file` resource reports `changed` — the agent wrote the file through a tool after the last `stat` — a bar above the path row says `文件已被修改，显示的还是旧内容。` / `The file has changed; this is the older text.` with a `重新载入` / `Reload` button. Only the click does two things at once: `meta.reload()` (a fresh `stat`, which clears `changed`) and `reloadPages` (drop every page, read the first one again). The scroll offset is kept, so the reader stays where they were. Nothing else triggers a reload: the tree and the preview do not watch the filesystem, and an external edit is not announced. A resource that turns `failed` — the file deleted, or the Host refusing it — puts a failure bar in the same place, its line from `failure-line.ts` and the same reload button, ahead of any pending `changed`; the pages already read stay beneath it.
 
-The body's header is one row: the file's path as the address names it on the left (12px, tertiary colour, one line, ellipsis when it overflows, full path on hover) and two 24px controls at its right end — a wrap toggle (`自动换行` / `Wrap lines`, pressed state shown, **on by default** per tab: long lines wrap and never scroll horizontally until the reader turns it off, whereupon the file body scrolls horizontally on its own) and a reload button (`重新读取文件` / `Read the file again`) that does exactly what the change bar's button does. Neither control is ever disabled. The preview takes the pane body's full height (`height: 100%` against the pane body, which is a block scroller of definite height) so a short file leaves no separately styled space below it, and the file body — monospace, 13px, line height 1.6, 10px vertical padding — is the only scroller: the header and the change bar stay put while a long file scrolls under them.
+The body's header is one row: the full file path on the left and the matching-renderer menu, conditional wrap toggle, and reload button on the right. The [Document Preview README](../../../../packages/client/ui-sidebar-documentpreview/README.md) owns the current controls and renderer behavior. The preview takes the pane body's full height, and its document body is the scroller beneath the fixed header and change bar.
 
 A failed page keeps the pages already shown and adds one sentence at the end of the loaded text, in terms of the file rather than the transport, with a `重试` / `Retry` button that reads the same page again: `workspace-file/not-found` `这个文件不在了。可能已被移动或删除。` / `That file is gone. It may have been moved or deleted.`; `workspace-file/outside-workspace` `这个文件在工作区之外，侧栏不会读取它。` / `That file is outside the workspace, so the sidebar will not read it.`; `workspace-file/too-large` `这一页太大，侧栏不读取超过 {limit} 的页。` / `That page is too large; the sidebar does not read pages above {limit}.` with the byte cap rendered as `2 MB`; `workspace-file/not-text` `这不是文本文件，没法在这里查看。` / `That is not a text file, so it cannot be shown here.`; `workspace-file/not-regular-file` `这不是一个普通文件，没有可显示的文本。` / `That is not a regular file, so it has no text to show.`; any other failure, carrier or unclassified, `读取失败：{message}` / `Read failed: {message}` with the failure's own message. The mapping lives in `failure-line.ts`, apart from the component so it is testable on its own; a code the reader does not name falls to the generic line carrying the carrier's message. A directory or a binary file therefore shows one failure line and nothing else; an empty file shows the header and an empty body with no marker.

 `text` 是 Session 作用域文件的兜底查看器。它的注册定义是 `{ id: '@deepseek-ai/dsh-client-ui-sidebar-documentpreview', kind: 'text', patterns: ['dsh-resource://file/**'], priority: 'fallback', canOpen, title: basenameOf }`。`canOpen` 只接受解析后 scope 为 `session` 的地址。pattern 含 `:`，因此匹配整个地址；`fallback` 是最低档，所以 `extension` 或 `builtin` 档上一个 pattern 更窄的类型（比如 `*.png`）接走那些地址，其余一切落到这里，而 text 类型对任何文件都留在候选列表中。`id` 是包名，兼作体坑位的 `key`，于是一个接管了 `text` kind 的扩展不可能让坑位误拿到这个体。标题是地址解码后的最后一段：整个地址仍是内容身份——不同目录下同名的两个文件、或同一路径在两个会话之下，是两个 tab——只有 chip 上的文字被缩短。
 
 tab 的地址是 `dsh-resource://file/session/<sessionId>/<相对该会话工作区根的路径>` 或 `dsh-resource://file/absolute/<绝对路径>`（[Workspace Files](../architecture/2026-09-05-workspace-files-service.zh.md) 拥有这套语法及 `dsh-util-workspace-path` 里的 `fileAddressFor` / `parseFileAddress` 助手）。预览从不自己拆这个串：`rpc.ts` 里的 `hostFileOf` 调 `parseFileAddress` 得到端点所需的 `{ sessionId, path }`——`session` 地址在它命名的会话下以 Host 解析的相对路径读取，`absolute` 地址在坑位被挂载的会话下以绝对路径读取——畸形地址直接抛错，那是程序错误，因为注册表把每个 `file` 地址都路由给这个类型，而造地址的调用方本应使用助手。

 文件变了只提示，不应用。当 `file` 资源报告 `changed`——agent 在上次 `stat` 之后经工具写了该文件——路径行上方出现一条提示 `文件已被修改，显示的还是旧内容。` / `The file has changed; this is the older text.`，带一个 `重新载入` / `Reload` 按钮。只有点击才同时做两件事：`meta.reload()`（重新 `stat`，清掉 `changed`）与 `reloadPages`（丢掉所有页，重读第 1 页）。滚动位置保留，读者停在原处。没有别的东西触发重载：树和预览都不监听文件系统，外部编辑不会被提示。资源变为 `failed`——文件被删，或 Host 拒绝——时，同一位置出现一条失败条，句子来自 `failure-line.ts`，带同一个重新载入按钮，并优先于尚未处理的 `changed`；已读的页留在它下方。
 
-体的头部是一行：左边是地址所命名的文件路径（12px、三级色、单行、溢出省略号、悬停显示完整路径），右端是两个 24px 控件——换行开关（`自动换行` / `Wrap lines`，显示按下态，**默认开**、按 tab 记：长行折行、绝不横向滚动，直到读者关掉它，此后文件体自己横向滚动）与一个重新读取按钮（`重新读取文件` / `Read the file again`），做的恰是变更提示条按钮做的事。两个控件都永不禁用。预览占满 pane 体的全部高度（对 pane 体取 `height: 100%`；pane 体是高度确定的块级滚动容器），于是短文件下方不留另一块样式不同的空白，而文件体——等宽、13px、行高 1.6、上下 10px 内边距——是唯一的滚动者：长文件在头部与变更提示条之下滚动，二者不动。

It may have been moved or deleted.`；`workspace-file/outside-workspace` `这个文件在工作区之外，侧栏不会读取它。` / `That file is outside the workspace, so the sidebar will not read it.`；`workspace-file/too-large` `这一页太大，侧栏不读取超过 {limit} 的页。` / `That page is too large; the sidebar does not read pages above {limit}.`，字节上限渲染为 `2 MB` 这样的形式；`workspace-file/not-text` `这不是文本文件，没法在这里查看。` / `That is not a text file, so it cannot be shown here.`；`workspace-file/not-regular-file` `这不是一个普通文件，没有可显示的文本。` / `That is not a regular file, so it has no text to show.`；其余任何失败，无论载体层还是未分类，`读取失败：{message}` / `Read failed: {message}` 并带上失败自身的消息。映射住在 `failure-line.ts` 里，与组件分开以便单独测试；读者未命名的错误码落到带传输层消息的通用句。目录或二进制文件因此只显示一行失败说明；空文件显示头部与一个空的体，没有任何标记。

 Document implementations register metadata with `ctx.documentPreviews.register({ id, extensions, priority, title, loading, wrap? })` and a body under the same `id` in the keyed, Session-scoped `sidebar.right.tab.document` child slot. Own both registrations with effects and wait for the child slot through `ctx.slots.inject`. Bodies receive `resourceAddress`, prepared `content`, `wrap`, and the standard `useTabInfo`/`useResource` hooks; they do not receive a custom resource loader. Metadata declares `loading: 'text-pages'` or `'bytes-complete'`. The registry retains all matching alternatives: `extension` (the default) ranks above `builtin`, then longer suffixes rank first, then registration order. The dropdown preserves a selected implementation while it remains available; removing it selects the next candidate. Builtin bodies use these same registrations.

The Host's `maxFileBytes` cap rejects oversized files rather than truncating them. PDF copies retained bytes before worker transfer, keeping the Preview buffer usable. Bytes stay in transient view state, never persisted layouts or Session JSONL. Loading-mode changes retire previous results.
 - **Reload** — only the current Preview tab rereads through its Remote callbacks, preserving its scroll preference and retiring older requests. Its change notice compares the read version and the observation captured at read start with later `resource.value.version`; an already observed version does not become a new change after refresh.

 `text` is the fallback viewer for Session-scoped files. Its registration is `{ id: '@deepseek-ai/dsh-client-ui-sidebar-documentpreview', kind: 'text', patterns: ['dsh-resource://file/**'], priority: 'fallback', canOpen, title: basenameOf }`. `canOpen` accepts only addresses whose parsed scope is `session`. The pattern contains `:` and so matches the whole address; `fallback` is the lowest band, so a type at `extension` or `builtin` with a narrower pattern (`*.png`, say) takes those addresses and everything else lands here, while the text type stays in the candidate list for any file. The `id` is the package name and doubles as the `key` of the body seat, so an extension that takes the `text` kind over cannot make the seat pick up this body by mistake. The title is the address's decoded last segment: the whole address stays the content identity — two files with one name in different directories, or one path under two sessions, are two tabs — and only the chip text is shortened.
 
-A tab's address is `dsh-resource://file/session/<sessionId>/<path relative to that session's workspace root>` or `dsh-resource://file/absolute/<absolute path>` ([Workspace Files](../architecture/2026-09-05-workspace-files-service.md) owns the grammar and the `fileAddressFor` / `parseFileAddress` helpers in `dsh-util-workspace-path`). The preview never splits the string itself: `hostFileOf` in `rpc.ts` calls `parseFileAddress` and yields the `{ sessionId, path }` the endpoint takes — a `session` address reads under the session it names with the relative path the Host resolves, an `absolute` address reads under the session the slot was mounted for with the absolute path — and a malformed address throws, a programming error, because the registry routes every `file` address to this type and a caller building one is expected to use the helper.
+A tab uses `dsh-resource://file/session/<sessionId>/<path>`, where the path may be relative or absolute ([Workspace Files](../architecture/2026-09-05-workspace-files-service.md) owns the grammar and the `fileAddressFor` / `parseFileAddress` helpers). `hostFileOf` accepts only this Session scope and takes both Session and path from the address; a Session-less `absolute` address is not claimed. A malformed claimed address throws as a programming error.
 
-Metadata and content come from different places. `useResource<'file'>(tab.contentId)`, the global standard hook from the [client resource model](../architecture/2026-09-05-client-resource-model.md), yields `{ absolutePath, version, bytes, changed }` from the `file` provider; the body reads `changed` and the resource's failed state. Content is the type's own business, read one page of lines at a time through `remote.workspaceFiles.read(sessionId, path, { offset }, signal)` with no `limit`, so the page length is the Host's configured cap (`maxLines`, 5000 lines by default, and a page may not exceed `maxBytes`, 2 MB by default). The first mount reads the first page; a **Load more** button at the end of the loaded text reads the next page until `eof`, disabled and reading `正在读取…` / `Reading…` while a read is in flight, and absent once the file has ended or a page failed. Pages are appended in file order with no separators and no line numbers, each carrying its line count (`lines`) so one empty line and a page past the end read differently. A first page from a newer file version replaces the pages of the older one; a later page from a newer version is not adopted and the walk restarts from the first page, so the body never shows two versions at once. The face keeps a request generation per tab: a reload bumps it, and a page settling from an older generation writes nothing. A tab switched away from and back reads nothing, because the pages live in the store, not the body.
+Metadata and content come from different places. `useResource<'file'>(tab.contentId)`, the global standard hook from the [client resource model](../architecture/2026-09-05-client-resource-model.md), yields `WorkspaceFileStat`; the body compares that observed version with the version of its loaded content. The Preview face reads text through `remote.workspaceFiles.read` and complete bytes through `readAll`. A later text page from a newer version restarts from page one, and a retired request cannot write after reload or tab disposal. The [Document Preview decision](../architecture/2026-09-08-document-preview-operations.md) owns renderer-specific loading.
 
 The store is Slot-standard: one exclusive instance per session, bucketed by tab id, holding `{ version, pages, eof, loading, failure, scrollTop, wrap, revision }`. Bucketing by tab, not by file, is deliberate — two tabs of one file scroll independently. The face (`loadPage`, `reloadPages`) is the only asynchronous half: it marks a read in flight, awaits the Remote result, and writes a page or a failure through the store's actions, writing nothing if the owner's `signal` has fired. The `signal` also ends the bucket: the face arms one abort listener per tab at the tab's first read, and that listener forgets the bucket — not the body, which mounts and unmounts as tabs switch; a tab that never read has no bucket and no listener, and a record can end while its body is unmounted behind another tab. Scroll offset, wrap, and the navigation already answered therefore outlive the body: a tab comes back where the reader left it rather than re-reading or jumping again. Nothing persists across a page reload.
 
 Navigation is a `line`. The `read` tool row passes its 1-based `offset` as `openResource(address, { params: { line } })`, and the produced-file chip passes nothing; the body narrows `navigation.params` to `SidebarRightResourceParamsMap['file']` (`{ line?: number }`, declared by the `file` type's owner) without runtime validation, because caller and body meet at a typed same-process boundary. If the loaded pages do not reach the line, the body reads the next page, again, until they do or the file ends — pages load in order; there is no seek — then scrolls the line to the top of the body and highlights it, once per `navigation.revision`. The store records the answered revision, so a body remounting for the same revision restores the scroll offset instead of jumping, and a new `openResource` for the same file (revealed, not duplicated) arrives as a new revision and jumps again. A line past the end of the file stops silently at `eof`; a page that fails while walking stops the walk and shows the failure line.
 
-A changed file is announced, not applied. When the `file` resource reports `changed` — the agent wrote the file through a tool after the last `stat` — a bar above the path row says `文件已被修改，显示的还是旧内容。` / `The file has changed; this is the older text.` with a `重新载入` / `Reload` button. Only the click does two things at once: `meta.reload()` (a fresh `stat`, which clears `changed`) and `reloadPages` (drop every page, read the first one again). The scroll offset is kept, so the reader stays where they were. Nothing else triggers a reload: the tree and the preview do not watch the filesystem, and an external edit is not announced. A resource that turns `failed` — the file deleted, or the Host refusing it — puts a failure bar in the same place, its line from `failure-line.ts` and the same reload button, ahead of any pending `changed`; the pages already read stay beneath it.
+A changed file is announced, not applied. The body compares the loaded version and the observation captured at read start with later `WorkspaceFileStat.version`; a difference shows the change bar. Reload rereads only this tab through the Preview face and does not mutate shared resource metadata or another tab. A resource failure takes the same bar's place above any content already loaded.
 
 The body's header is one row: the full file path on the left and the matching-renderer menu, conditional wrap toggle, and reload button on the right. The [Document Preview README](../../../../packages/client/ui-sidebar-documentpreview/README.md) owns the current controls and renderer behavior. The preview takes the pane body's full height, and its document body is the scroller beneath the fixed header and change bar.
 
-A failed page keeps the pages already shown and adds one sentence at the end of the loaded text, in terms of the file rather than the transport, with a `重试` / `Retry` button that reads the same page again: `workspace-file/not-found` `这个文件不在了。可能已被移动或删除。` / `That file is gone. It may have been moved or deleted.`; `workspace-file/outside-workspace` `这个文件在工作区之外，侧栏不会读取它。` / `That file is outside the workspace, so the sidebar will not read it.`; `workspace-file/too-large` `这一页太大，侧栏不读取超过 {limit} 的页。` / `That page is too large; the sidebar does not read pages above {limit}.` with the byte cap rendered as `2 MB`; `workspace-file/not-text` `这不是文本文件，没法在这里查看。` / `That is not a text file, so it cannot be shown here.`; `workspace-file/not-regular-file` `这不是一个普通文件，没有可显示的文本。` / `That is not a regular file, so it has no text to show.`; any other failure, carrier or unclassified, `读取失败：{message}` / `Read failed: {message}` with the failure's own message. The mapping lives in `failure-line.ts`, apart from the component so it is testable on its own; a code the reader does not name falls to the generic line carrying the carrier's message. A directory or a binary file therefore shows one failure line and nothing else; an empty file shows the header and an empty body with no marker.
+A failed read keeps content already shown and adds a localized failure with a retry action. The Preview names actionable file failures and falls back to the carrier message for other codes; `outside-workspace` belongs to directory listing and is not a Preview-specific failure.

-tab 的地址是 `dsh-resource://file/session/<sessionId>/<相对该会话工作区根的路径>` 或 `dsh-resource://file/absolute/<绝对路径>`（[Workspace Files](../architecture/2026-09-05-workspace-files-service.zh.md) 拥有这套语法及 `dsh-util-workspace-path` 里的 `fileAddressFor` / `parseFileAddress` 助手）。预览从不自己拆这个串：`rpc.ts` 里的 `hostFileOf` 调 `parseFileAddress` 得到端点所需的 `{ sessionId, path }`——`session` 地址在它命名的会话下以 Host 解析的相对路径读取，`absolute` 地址在坑位被挂载的会话下以绝对路径读取——畸形地址直接抛错，那是程序错误，因为注册表把每个 `file` 地址都路由给这个类型，而造地址的调用方本应使用助手。
+tab 使用 `dsh-resource://file/session/<sessionId>/<path>`，其中路径可以是相对路径或绝对路径（[Workspace Files](../architecture/2026-09-05-workspace-files-service.zh.md)负责该语法与 `fileAddressFor` / `parseFileAddress` 辅助函数）。`hostFileOf` 只接受这种 Session scope，并从地址取得 Session 与路径；不认领不带 Session 的 `absolute` 地址。被认领的地址若格式错误，则作为程序错误抛出。
 
-元数据与内容来自不同的地方。`useResource<'file'>(tab.contentId)`——[client 资源模型](../architecture/2026-09-05-client-resource-model.zh.md)提供的全局标准 hook——从 `file` 提供者得到 `{ absolutePath, version, bytes, changed }`；体读 `changed` 与资源的失败态。内容是类型自己的事，经 `remote.workspaceFiles.read(sessionId, path, { offset }, signal)` 一次读一页行，不传 `limit`，因此页长就是 Host 配置的上限（`maxLines`，默认 5000 行；且一页不得超过 `maxBytes`，默认 2 MB）。首次挂载读第 1 页；已加载文本末尾的 **加载更多** 按钮读下一页直到 `eof`，读取进行中它禁用并显示 `正在读取…` / `Reading…`，文件读完或某页失败后消失。页按文件顺序追加，没有分隔也没有行号，每页带着自己的行数（`lines`），单个空行与越过文件末尾的页由此区分。来自更新文件版本的第一页替换旧版本的页；更新版本的后续页不被采用，从第一页重新走一遍，于是体永不同时显示两个版本。face 按 tab 记请求代次：重载递增它，旧代次结算的页什么也不写。切走再切回的 tab 什么都不读，因为页住在 store 里而不是体里。
+元数据与内容来自不同的地方。`useResource<'file'>(tab.contentId)`——[client 资源模型](../architecture/2026-09-05-client-resource-model.zh.md)提供的全局标准 hook——产生 `WorkspaceFileStat`；正文把其观察版本与已加载内容版本比较。Preview face 通过 `remote.workspaceFiles.read` 读取文本，通过 `readAll` 读取完整字节。后续文本页若来自更新版本，则从第一页重新开始；被重载或 tab 销毁淘汰的请求不能再写入。[Document Preview 决议](../architecture/2026-09-08-document-preview-operations.zh.md)负责各渲染器的加载方式。
 
 store 是 Slot 标准件：每会话一个独占实例，按 tab id 分桶，持有 `{ version, pages, eof, loading, failure, scrollTop, wrap, revision }`。按 tab 而非按文件分桶是有意的——同一文件的两个 tab 各自滚动。face（`loadPage`、`reloadPages`）是唯一的异步半边：它标记读取进行中，等待 Remote 结果，再经 store 的 action 写入一页或一次失败；若 owner 的 `signal` 已触发则什么也不写。`signal` 同时终结这个桶：face 在 tab 首次读取时挂一个 abort 监听器，由它忘掉桶——不是体，体随 tab 切换反复挂载卸载；从未读过的 tab 没有桶也没有监听器，而 tab 记录可能在其体被另一 tab 挡住而卸载时结束。因此滚动位置、换行与已答过的导航都活得比体久：tab 回来时停在读者离开的地方，而不是重读或再跳一次。刷新页面后什么都不保留。
 
 导航是一个 `line`。`read` 工具行把它 1 起的 `offset` 以 `openResource(address, { params: { line } })` 传来，产物 chip 什么都不传；体把 `navigation.params` 收窄为 `SidebarRightResourceParamsMap['file']`（`{ line?: number }`，由 `file` 类型的拥有者声明），不做运行时校验，因为调用方与体相遇在同进程的类型化边界上。已加载的页够不到该行时，体读下一页，再读，直到覆盖它或文件结束——页按顺序加载，没有 seek——然后把该行滚到体顶部并高亮，每个 `navigation.revision` 一次。store 记下已答过的 revision，于是同一 revision 下重新挂载的体恢复滚动位置而不再跳；对同一文件再次 `openResource`（聚焦而非复制）以新 revision 到来并再跳一次。超出文件末尾的行在 `eof` 处静默停下；补页途中失败的页终止补页并显示失败行。
 
-文件变了只提示，不应用。当 `file` 资源报告 `changed`——agent 在上次 `stat` 之后经工具写了该文件——路径行上方出现一条提示 `文件已被修改，显示的还是旧内容。` / `The file has changed; this is the older text.`，带一个 `重新载入` / `Reload` 按钮。只有点击才同时做两件事：`meta.reload()`（重新 `stat`，清掉 `changed`）与 `reloadPages`（丢掉所有页，重读第 1 页）。滚动位置保留，读者停在原处。没有别的东西触发重载：树和预览都不监听文件系统，外部编辑不会被提示。资源变为 `failed`——文件被删，或 Host 拒绝——时，同一位置出现一条失败条，句子来自 `failure-line.ts`，带同一个重新载入按钮，并优先于尚未处理的 `changed`；已读的页留在它下方。
+文件变了只提示，不应用。正文把已加载版本及读取开始时捕获的观察版本与后续 `WorkspaceFileStat.version` 比较；不同则显示变更提示。重新载入只通过 Preview face 重读当前 tab，不修改共享资源元数据或其他 tab。资源失败占用同一个提示位置，已加载内容仍保留在下方。
 
 正文头部为一行：左侧显示完整文件路径，右侧放匹配渲染器菜单、按条件出现的换行开关和重新载入按钮。[Document Preview README](../../../../packages/client/ui-sidebar-documentpreview/README.zh.md)负责当前控件与渲染器行为。预览占满 pane 正文的全部高度，其文档正文是固定头部与变更提示条下方的滚动区域。
 
-某页失败时，已显示的页保留，并在已加载文本末尾加一句以文件而非传输为主语的说明，带一个重读同一页的 `重试` / `Retry` 按钮：`workspace-file/not-found` `这个文件不在了。可能已被移动或删除。` / `That file is gone. It may have been moved or deleted.`；`workspace-file/outside-workspace` `这个文件在工作区之外，侧栏不会读取它。` / `That file is outside the workspace, so the sidebar will not read it.`；`workspace-file/too-large` `这一页太大，侧栏不读取超过 {limit} 的页。` / `That page is too large; the sidebar does not read pages above {limit}.`，字节上限渲染为 `2 MB` 这样的形式；`workspace-file/not-text` `这不是文本文件，没法在这里查看。` / `That is not a text file, so it cannot be shown here.`；`workspace-file/not-regular-file` `这不是一个普通文件，没有可显示的文本。` / `That is not a regular file, so it has no text to show.`；其余任何失败，无论载体层还是未分类，`读取失败：{message}` / `Read failed: {message}` 并带上失败自身的消息。映射住在 `failure-line.ts` 里，与组件分开以便单独测试；读者未命名的错误码落到带传输层消息的通用句。目录或二进制文件因此只显示一行失败说明；空文件显示头部与一个空的体，没有任何标记。
+读取失败时保留已显示的内容，并增加本地化失败说明与重试操作。Preview 为可处理的文件错误提供专用文案，其他代码使用载体消息兜底；`outside-workspace` 属于目录列举，不是 Preview 专用失败。

Subject: [PATCH 019/164] feat(feedback): open one feedback dialog from
 /feedback and Dislike, with categories and a toast

Dislike and a bare /feedback open the Session's feedback dialog, which
collects one of seven fixed categories and an optional description and
records through the messageFeedback put or the new sessionFeedback
Remote; Like records at once. A recorded rating shows the filled glyph
and every submission is acknowledged by a toast. feedback/record and
MessageFeedbackItem carry the optional category; the note popover, its
layout scenario, and the clearNote/clear verbs are removed. ui-commands
gains the action command kind the /feedback decoration runs as.

Closes #3515

+# Agent Note: Feedback dialog, categories, and the acknowledgement toast
+
+Status: implemented
+
+English | [中文](2026-09-08-feedback-dialog-and-categories.zh.md)
+
+## Problem
+
+The Web client had two disconnected feedback paths with no visible outcome. `/feedback <text>` recorded a Session remark and rendered an acknowledgement row in the transcript; the Like/Dislike pair recorded a rating at once, with a note popover anchored under the row for free text. Neither path told the user what was submitted or where it went, neither collected a category, and a Dislike, the case in which a user is most willing to explain, asked nothing. Issue #3515 and the design doc for it ask for one dialog reachable from the composer menu, from a bare `/feedback`, and from Dislike, with seven fixed categories, an optional description, a success toast, and a filled glyph for a recorded rating, while Like keeps recording at once.
+
+## Decision
+
+`command-feedback` owns the category taxonomy as the `FeedbackCategory` union and the `FEEDBACK_CATEGORIES` tuple in its client-safe `./types` export, and `feedback/record` becomes `{ text?, category? }`: blank text is recorded as absent, and an entry with neither member still records, because the log delivery that the feedback authorizes is the content. The same package publishes the `sessionFeedback.record` Remote through `TypertRemoteService`, resolving the live Session by id and calling the existing `recordFeedback` producer, so the dialog records the same event as the command without command bookkeeping. `message-feedback` adds the optional `category` to `MessageFeedbackItem` and `MessageFeedbackPutRequest`, validates stored values against the tuple, and counts a category change as a material edit.
+
+`ui-message-feedback` becomes the Web feedback surface. A per-session `FeedbackSurface` owns the message-feedback controller, a `FeedbackDialogController` for the draft, the submission, and the toast sequence, and the routing between them: a message target puts a negative judgment with the dialog's category and note through the message controller, the Session target records through `ctx.remote.sessionFeedback`. A `FeedbackDialog` entry of `conversation.input.overlay` renders the Modal and Toast primitives from the dialog store. A decoration on the Host's `feedback` command opens the dialog for the Session from a menu pick or a bare Enter while `/feedback <text>` still reaches the Host; it uses the `action` kind this PR adds to `CommandUiSpec`, a bare invocation that consumes the trigger token and runs a client callback without submitting anything. Dislike opens the same dialog for the message. Like calls `toggle`, which now reports the rating it committed, so the row acknowledges a recorded Like and stays silent on a retraction. The note popover, `clearNote`, and `clear` are removed: the dialog is the only note editor, a rating switch stores the bare judgment, and clicking a recorded rating retracts it.
+
+The dialog is the shared Modal card at the design's width; the design's checkbox for including the conversation log is not built, because the log travels with every feedback event and is not optional. An oversized description still fails on submit with `note-too-large`; the dialog stays open with the code.
+
+## Alternatives considered
+
+**Encode the category into the note text.** A prefix in free text is not filterable without parsing and would leak into the verbatim note that telemetry uploads; a durable id in the payload is what a consumer can group by.
+
+**Submit the dialog through the command plane as `/feedback <text>`.** The command rejects empty text, cannot carry a category, and writes an acknowledgement row the design replaces with a toast; the Remote records the same event with neither constraint.
+
+**Keep the note popover beside the dialog.** Two editors for one note with different reachability would leave the row two-line at some widths, the defect the popover was introduced to avoid, and the design shows only the thumbs.
+
+**A Toast per message control.** The composer overlay already mounts once per Session, and the dialog owns the toast sequence, so one owner serves the Like path and the dialog path alike.
+
+**A dialog kind in `CommandUiSpec`.** An action that consumes the token and runs a client callback is all the dialog needs; PR #3745 introduces the same `action` kind for its File row, so whichever lands second keeps one definition.
+
+## Consequences
+
+Adding a category means adding it to the union, to the Host tuple, to the dialog's chip record, and to the `feedback` dictionaries; the client bundle purity gate forbids a value import from a Host package, so the dialog restates the taxonomy as a `Record<FeedbackCategory, true>` whose key order is the chip order and whose completeness the compiler checks. The frozen released-v2 payload inventory still lists `feedback/record` as `text` only: it governs artifacts migrated from older generations, which cannot carry the new members, while equal-version restoration applies the installed vocabulary. The `message-feedback-layout` web scenario that pinned the popover's geometry is deleted with the popover. The message-feedback and feedback-release web goldens and the feedback subsystem doc changed in the same PR; the `/feedback <text>` command path and its SDK expected outputs are unchanged.

+# Agent Note: 反馈弹窗、分类与确认 toast
+
+Status: implemented
+
+[English](2026-09-08-feedback-dialog-and-categories.md) | 中文
+
+## 问题
+
+Web 客户端有两条互不相连的反馈路径，且都没有可见结果。`/feedback <text>` 记录一条 Session 备注并在转录里渲染一行确认；赞踩对立即记录评分，自由文本则通过锚定在该行下方的备注浮层填写。两条路径都不告诉用户提交了什么、去了哪里，都不收集分类，而点踩这个用户最愿意解释的场景什么也不问。Issue #3515 及其设计稿要求：一个弹窗，可从输入框菜单、不带文本的 `/feedback` 和点踩三处打开，带七个固定分类、可选描述、成功 toast，以及已记录评分的实心图标；点赞保持立即记录。
+
+## 决策
+
+`command-feedback` 在其客户端可用的 `./types` 导出中以 `FeedbackCategory` 联合类型与 `FEEDBACK_CATEGORIES` 元组拥有分类表，`feedback/record` 变为 `{ text?, category? }`：空白文本记为缺省，两个成员都没有的条目仍会记录，因为反馈所授权的日志投递本身就是内容。同一个包通过 `TypertRemoteService` 发布 `sessionFeedback.record` Remote，按 id 找到 live Session 后调用已有的 `recordFeedback` 生产方，因此弹窗记录的是与命令相同的事件，只是没有命令簿记。`message-feedback` 给 `MessageFeedbackItem` 与 `MessageFeedbackPutRequest` 加上可选 `category`，按元组校验已存值，并把分类变化算作实质编辑。
+
+`ui-message-feedback` 成为 Web 反馈界面。每个 Session 一个 `FeedbackSurface`，拥有消息反馈控制器、负责草稿、提交与 toast 序号的 `FeedbackDialogController`，以及两者之间的路由：消息目标经消息控制器 put 一条带弹窗分类与备注的差评，Session 目标经 `ctx.remote.sessionFeedback` 记录。`conversation.input.overlay` 的 `FeedbackDialog` 条目从弹窗 store 渲染 Modal 与 Toast 基元。宿主 `feedback` 命令上的装饰让菜单选中或不带参数的回车为 Session 打开弹窗，而 `/feedback <text>` 仍到达宿主；它使用本 PR 给 `CommandUiSpec` 新增的 `action` 种类：裸调用消费触发 token 后运行一个客户端回调，不提交任何内容。点踩为消息打开同一个弹窗。点赞调用 `toggle`，它现在会报告自己提交的评分，因此该行只对记录成功的点赞做确认，撤回时保持沉默。备注浮层、`clearNote` 与 `clear` 被移除：弹窗是唯一的备注编辑器，切换评分只存判断本身，再次点击已记录的评分即撤回。
+
+弹窗是共用的 Modal 卡片，宽度按设计稿；设计稿里「包括当前对话的日志」复选框不做，因为日志随每个反馈事件一起投递，不是可选项。超长描述仍在提交时以 `note-too-large` 失败；弹窗带着失败码保持打开。
+
+## 考虑过的替代方案
+
+**把分类编进备注文本。** 自由文本里的前缀不解析就无法过滤，还会混进遥测上传的原样备注；载荷里的持久 id 才是消费方能分组的东西。
+
+**让弹窗经命令平面以 `/feedback <text>` 提交。** 命令拒绝空文本、带不了分类，还会写一行设计稿已用 toast 取代的确认；Remote 记录同一个事件且没有这两个约束。
+
+**在弹窗之外保留备注浮层。** 同一条备注有两个可达性不同的编辑器，会让该行在某些宽度下变成两行，正是当初引入浮层要避免的缺陷，而且设计稿只有两个拇指。
+
+**每个消息控件各自一个 Toast。** 输入框浮层已经按 Session 挂载一次，弹窗又拥有 toast 序号，因此一个持有者同时服务点赞路径与弹窗路径。
+
+**在 `CommandUiSpec` 里新增 dialog 种类。** 一个消费 token 后运行客户端回调的 action 已经够用；PR #3745 为它的「文件」行引入了同一个 `action` 种类，后合并的一方保留一份定义即可。
+
+## 后果
+
+新增分类意味着把它加进联合类型、宿主元组、弹窗的标签记录和 `feedback` 词典；客户端打包纯度门禁止从宿主包做值导入，因此弹窗以 `Record<FeedbackCategory, true>` 重述分类表，键的顺序就是标签顺序，完整性由编译器检查。冻结的已发布 v2 载荷清单仍把 `feedback/record` 列为仅有 `text`：它管辖从旧代际迁移来的产物，那些产物不可能携带新成员，而同版本恢复应用的是已安装词汇。固定浮层几何的 `message-feedback-layout` Web 场景随浮层一起删除。message-feedback 与 feedback-release 的 Web 期望输出和反馈子系统文档在同一个 PR 中更新；`/feedback <text>` 命令路径及其 SDK 期望输出不变。

 ## Data and concurrency
 
-Current items are folded from canonical feedback events whose payload `sessionId` matches the owning Session. Each item carries a positive or negative rating, an optional note, Host-assigned `createdAt`/`updatedAt` timestamps, and its own opaque version. Versions are compared only for equality and only against the addressed message; callers do not order or synthesize them.

Versions are compared only for equality and only against the addressed message; callers do not order or synthesize them.
 
-`put` uses strict optimistic concurrency: every request for an existing item must match its current `ifVersion`, including a no-op. A conflict returns the authoritative current item (or `null`), so a caller can reconcile a lost response or a concurrent edit without another read. Deleting an already absent item succeeds. A per-Session queue serializes reads and mutations; cold mutations hold a persistence write handle across read, comparison, append, and flush. Matching no-ops append no event.

 The controls are the `feedback` entry (order 10) of the `conversation.chat.assistant-actions` list slot, which `ui-conversation` declares and renders inside the finalized assistant message's IconActions row. `AssistantMessageNode` carries the optional `messageId` from the `assistant/message` event. The field is absent on interruption-frozen partials, and the render site skips the slot when it is absent. The strip renders once per turn, on the closing assistant message: the Host accepts every append-origin step message as a target, but earlier steps of a multi-step turn render tool rows rather than a rateable body, so the UI exposes a narrower set than the Host contract allows.
 
 One `MessageFeedbackController` per Session backs every message control in that Session: a single `list` read seeds the whole transcript, deferred to first hover or focus rather than fired on mount. Each mutation sends the version that controller last observed as `ifVersion`; a `version-conflict` reply carries the authoritative item, so the controller reconciles from the reply instead of refetching. Mutations serialize per Session so a queued operation compares against the committed version. A `connection/reset` refreshes only Sessions already read.
 
+Like records the bare positive judgment at once and shows the acknowledgement toast. Dislike opens the Session's feedback dialog, the `feedback-dialog` entry of `conversation.input.overlay`: the shared Modal card with seven category chips and a detail box. Submit puts a negative judgment carrying the chosen category and the trimmed description, or neither. The same dialog opens for the Session from a bare `/feedback` — a decoration `ui-commands` routes as an `action` — and then records through `sessionFeedback.record`; `/feedback <text>` keeps the Host command path. Clicking a recorded rating retracts it.

 - The Web controller does not consume feedback log events, so a second tab's rating becomes visible on reconnect or on the next conflict reply rather than immediately.

 ## Summary
 
-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`.

 ## Summary
 
-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. Ratings and notes are log-only Session events: they never enter model context. Deletion retracts the current item without erasing its earlier log entries.
+This package is the Web GUI's feedback surface: the Like/Dislike pair in the finalized assistant message's action strip, the feedback dialog with its acknowledgement toast in the composer overlay, and a decoration that opens the dialog from a bare `/feedback`. Like records at once and shows the toast; Dislike opens the dialog, which collects a category and an optional description. One surface per Session backs every entry, so a single list read seeds the whole transcript and one dialog serves the Session and its messages. Ratings, categories, and notes are log-only Session events that never enter model context.

-Mount this plugin alongside `ui-conversation`; the Like/Dislike pair then appears in the action row of each turn's closing assistant message, between copy and branch. Clicking the recorded rating retracts the feedback; switching sides carries the existing note forward. The note editor is a dialog popover anchored under its trigger, so the row keeps its single line whether the editor is open or closed.
+Mount this plugin alongside `ui-conversation` and `ui-commands`; the Like/Dislike pair then appears in the action row of each turn's closing assistant message, between copy and branch, and the Feedback row of the composer menu opens the dialog. A recorded rating shows the filled glyph and stays visible without hover. Like records immediately and the toast thanks the user for the feedback. Dislike opens the dialog: seven category chips and a detail box, both optional; Submit records a negative judgment carrying whatever was filled in, and the conversation log travels with every feedback event. Clicking the recorded rating retracts it. A bare `/feedback`, picked from the menu or typed and sent without text, opens the same dialog for the Session; `/feedback <text>` keeps the Host command path and its acknowledgement row.
 
 ### Failures
 
-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 package contributes the `feedback` entry (order 10) of `conversation.chat.assistant-actions`, declared by ui-conversation and rendered inside the finalized assistant message's IconActions row. 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. 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. Mutations serialize per Session, so a queued operation always compares against the committed version.
+The package contributes the `feedback` entry (order 10) of `conversation.chat.assistant-actions`, declared by ui-conversation and rendered inside the finalized assistant message's IconActions row, and the `feedback-dialog` entry (order 2) of `conversation.input.overlay`, which renders the Modal and Toast primitives through body portals and centers the toast over the composer card it mounts inside. The `/feedback` decoration is an `action` registered through `ctx.commandUi.decorate`, so a menu pick or a bare Enter consumes the trigger token and opens the dialog while an argued line still reaches the Host command.
+
+Per Session, one `MessageFeedbackController` backs every message control and one `FeedbackDialogController` owns the dialog draft, the submission, and the toast sequence. The message controller reads `messageFeedback.list` once, deferred to the first hover or focus rather than fired on mount, and serializes mutations so each carries the version last observed; a `version-conflict` reply carries the authoritative item and reconciles the view without refetching. `toggle` reports the rating now committed, so the row acknowledges a recorded Like and not a retraction. The dialog controller submits by target: a message target puts a negative judgment with the dialog's note and category through the message controller, and the Session target records through `ctx.remote.sessionFeedback`. Success closes the draft and raises the toast; a late success from a superseded draft raises the toast without closing the new draft; a failure keeps the draft open with its code.

 ## 概述
 
-本包为 Web GUI 增加逐消息反馈：一对 Like/Dislike 按钮加一个可选备注，作为已定稿助手消息动作条的 `feedback` 条目贡献。它渲染在每个轮次的收尾助手消息上——多步骤轮次中较早的步骤产出工具行而非可评分正文。每个 Session 一个控制器支撑该 Session 内所有消息的控件，因此一次列表读取即可填充整段对话。评分与备注是仅写日志的 Session 事件：它们绝不进入模型上下文。删除会撤回当前条目，但不会抹除早先的日志记录。
+本包是 Web GUI 的反馈界面：已定稿助手消息动作条中的 Like/Dislike 对、输入框浮层中的反馈弹窗及其确认 toast，以及让不带文本的 `/feedback` 打开弹窗的装饰。点赞立即记录并显示 toast；点踩打开弹窗，弹窗收集分类与可选描述。每个 Session 一个 surface 支撑所有条目，因此一次列表读取即可填充整段对话，一个弹窗同时服务 Session 与其消息。评分、分类与备注是仅写日志的 Session 事件，绝不进入模型上下文。

-与 `ui-conversation` 一起挂载本插件；Like/Dislike 对随即出现在每个轮次收尾助手消息的动作行中，位于复制与分支之间。再次点击已记录的评分会撤回反馈；切换到另一侧会保留既有备注。备注编辑器是一个锚定在其触发按钮下方的对话框浮层，因此无论编辑器是否打开，该行都保持单行。

 ### 失败
 
-评分或列表加载失败在行内展示；备注保存失败在浮层内展示，面板保持打开以便修正草稿。只有已定稿的消息能到达该槽位——被中断冻结的部分输出不带 `messageId`，因此没有反馈控件。

 ## Summary
 
-`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. 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.
+`dsh-command-feedback` lets a user tell the harness what they think of a session. Typing `/feedback` plus a remark records it and acknowledges the session and anonymous user ids; the Web feedback dialog records a category and an optional description through the `sessionFeedback` Host Remote. Recording is immediate and never starts model work: the model neither sees the remark nor is interrupted by it. The package also owns the fixed category taxonomy every feedback surface files under. It ships with the standard `dsh` base and needs no configuration; headless, ACP, and JSON-RPC entry points provide no slash commands.

+### The Web feedback dialog
+
+In the Web client a bare `/feedback` — picked from the composer menu or typed and sent without text — opens the feedback dialog instead of the usage error. The dialog offers the seven categories below and a free-text box; every field is optional and an empty submission is accepted, and the conversation log travels with the recorded event as with every feedback event. It records through `sessionFeedback.record`, which appends the same `feedback/record` event without command bookkeeping and without an acknowledgement row; the dialog shows a toast instead.

 ### 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 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.
 
 ### 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).
+The producer trims the text, records blank text as absent, and writes one event into the session log even when the entry carries neither text nor category; the `/feedback` handler rejects empty input itself and is otherwise a thin wrapper over that same producer, and the `sessionFeedback.record` Remote resolves the live Session by id and calls it too, answering `session-not-found` when no live owner carries the id. Neither path starts model work. The write is eager but not flushed: the acknowledgement means the entry reached the log, not the disk. The first accepted command remark for a harness home also mints the anonymous user id the acknowledgement reports.

-- **没有反馈检索或管理 surface**——本包不为 `feedback/record` 提供检索、聚合、分类或面向模型的工具。

+- **没有反馈检索或管理 surface**——本包不为 `feedback/record` 提供检索、聚合或面向模型的工具。
+- **只有分类与文本**——一条条目至多携带一个分类和一个自由文本字符串，没有严重程度或关联事件链接。
+- **Remote 只服务 live Session**——没有 live 持有者的 Session，`sessionFeedback.record` 回答 `session-not-found`；弹窗打开期间 Session 退役时，Web 弹窗会报告该失败。
 - **不支持修改或撤回**——会话日志是仅追加的，本包也不新增 tombstone，因此错误的条目会一直保留在记录中，只能由后续条目取代。
 - **没有显式持久化屏障**——确认文本紧随追加而非 flush，因此紧临崩溃前记录的条目可能与其他未 flush 的尾部一同丢失。需要该保证的消费方可自行等待 `ctx.sessions.flush(session)`。
-- **新会话上没有可见的确认**——Web 转录只在会话激活后渲染命令行，因此在仍为空白的新会话上执行 `/feedback` 会记录事件但不会显示确认行。发送首条消息后再记录反馈即可正常渲染。
+- **新会话上没有可见的确认**——Web 转录只在会话激活后渲染命令行，因此在仍为空白的新会话上输入 `/feedback <text>` 会记录事件但不会显示确认行；弹窗的 toast 不依赖转录。

A put that repeats the stored rating, note, and category is a no-op: it returns the same item without appending an event. Deleting an absent item succeeds regardless of the supplied version, without appending an event. Recreating a deleted item starts a new creation time and ordering position.
 
 Targets must be non-empty assistant messages produced by append-origin events. User messages, empty assistant placeholders, and replacement-origin messages return `target-not-found`. Feedback survives restart; a fork starts without owned feedback even when its inherited prefix contains parent feedback.

 ## Consequences
 
-Adding a category means adding it to the union, to the Host tuple, to the dialog's chip record, and to the `feedback` dictionaries; the client bundle purity gate forbids a value import from a Host package, so the dialog restates the taxonomy as a `Record<FeedbackCategory, true>` whose key order is the chip order and whose completeness the compiler checks. The frozen released-v2 payload inventory still lists `feedback/record` as `text` only: it governs artifacts migrated from older generations, which cannot carry the new members, while equal-version restoration applies the installed vocabulary. The `message-feedback-layout` web scenario that pinned the popover's geometry is deleted with the popover. The message-feedback and feedback-release web goldens and the feedback subsystem doc changed in the same PR; the `/feedback <text>` command path and its SDK expected outputs are unchanged.

 A second hosted run of the same request implementation, [run 34033336246, job 101487216170](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34033336246/job/101487216170), records 145.644577, 144.204300, 143.072572, 145.985903, 146.834474 ms; median 145.644577 ms. It uses the same Ubuntu image and Node version but a different worker in Azure westus3 at merge commit `c366e49`. This faster run does not replace the eastus evidence or establish why the workers differ. The older self-hosted `VM-7-113-ubuntu-ci-9` run with Node 24.18.1 ([run 34021903421, job 101456015028](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34021903421/job/101456015028)) records 110.025154, 119.958978, 108.266860, 107.557950, 108.538902 ms; median 108.538902 ms. Its runner and Node version do not calibrate the standard hosted lane.
 
-The request-history CI expectation is 190 ms, rounded above this observed range. The enforced median budget is `ceil(190 × 1.25) = 238 ms`; the shared 2× reference-machine scale does not apply again to a CI measurement. This matches the direct-CI calibration method of the [63 ms Session-reopen budget](../../../../benchmarks/session-open/session-open.bench.ts), rather than relabeling the M4 reference as hosted evidence. The 238 ms budget remains below the isolated original implementation’s 246.130875 ms M4 median.
+The current request-history median limit is 297 ms. It is the largest integer within a 25% increase from the initial 238 ms limit: `floor(238 × 1.25) = 297`, an increase of 24.79%. This allowance belongs only to `agent-continuation/request-history`; the shared time scale, variance headroom, other time limits, memory limits, sample count, and workload remain unchanged.
 
-Deterministic controls call the same `assertRequestHistoryBudget` assertion as the timed case. They accept the recorded hosted median and maximum (185.042397 ms), reject the recorded original M4 median, and reject a synthetic 250 ms median from 248, 250, 252, 251, 249 ms inputs. The synthetic inputs model a material regression; they are not runtime measurements. Replaying recorded values verifies the assertion, not a new hosted run. The acceptance control fails at 175 ms before calibration; all three controls and the five request-freeze behavior tests pass at 238 ms.
+The standard GitHub Actions `ubuntu-24.04` runner group reports the same image `20260831.293.1` and Node 24.20.0 for the two release measurements below. The workers differ (`1000050430` and `1000050689`), but their hardware and resource conditions are not established by the logs. The request-history runtime and workload are identical between the two heads: 800 historical turns, four tools per historical turn, 40 live requests, and 13,925 final events. The earlier reference run supplies another slow observation.

+The first two jobs also differ across tool continuation (483.877/698.657 ms), catalog (612.127/1009.367 ms), and profile continuation (2438.362/3854.950 ms). These observations establish broad hosted execution-time variation; they do not identify a hardware fault or a runtime regression. Among these four continuation scenarios, only request history crosses its limit in the slower release run.
+
+A bounded profile of `a0a61a8237` on Apple M4 Pro / Node 24.19.0 retains five fresh-process totals: 70.198916, 67.432250, 65.151208, 66.473292, 71.049667 ms; median 67.432250 ms. Every sample completes the same 40 requests and 13,925 events. Sampling attributes 38.082 ms inclusive time to adapter dispatch, including 10.878 ms of required file-content traversal; system-node scanning takes 4.127 ms, while the one-time restored-event reversal takes 0.291 ms outside the timed turns. Removing the latter cannot explain the observed turn cost. Caching projected content or system nodes adds immutability or invalidation obligations beyond this bounded allowance. Runtime code is unchanged.
+
+Deterministic controls call the timed case's `assertRequestHistoryBudget`. They accept the recorded 185.042397 ms maximum and the two slower hosted medians, while rejecting a synthetic 310 ms median from 308, 310, 312, 311, 309 ms inputs. The slower-host acceptance control reproduces `265.796833 > 238` before the allowance; the complete owner file passes 11 tests at 297 ms. Replaying recorded values validates the assertion, not a new hosted run. The historical 250 ms synthetic case and the 246.130875 ms original M4 measurement fit this allowance and are no longer rejection controls; original/optimized M4 measurements remain evidence of the freeze implementation's gain.

+# Agent Note: User-patch transactions control filesystem event delivery
+
+Status: implemented
+
+English | [中文](2026-09-09-user-patch-hmr-test-delivery.zh.md)
+
+## Problem
+
+The [macOS Sandbox run](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34238200206/job/102101292119) times out while waiting for the first user-patch addition. Concurrent local reproductions show no filesystem notification reaching HMR. A polling variant also misses a subsequent edit while HMR has no pending refresh. These failures prevent the transaction assertions from exercising the parser, activation, and rollback behavior they own.
+
+## Decision
+
+The [user-patch transaction test](../../../../packages/boot/app-boot/tests/user-patches.spec.ts) writes real patch files and delivers their add, change, and unlink events through a Chokidar watcher without native watch handles. HMR registration, refresh serialization, Include recomposition, plugin activation, failure broadcasting, rollback, and recovery remain real. The fixture restores its watcher factory and disposes the Context even when setup fails before the local cleanup block.
+
+The separate [HMR config tests](../../../../packages/boot/app-boot/tests/hmr-config.spec.ts) own native notification delivery, including add/change/unlink, initially absent parents, and filesystem aliases. The transaction test does not establish operating-system delivery guarantees.
+
+## Alternatives considered
+
+**Native notifications for every transaction assertion.** Rejected because it repeats the native delivery dependency across each parser and activation state transition. A missing event obscures which downstream behavior is broken.
+
+**Polling and fixed settling delays.** Rejected because neither acknowledges delivery of the next edit. Chokidar readiness does not expose completion of Node's asynchronous initial polling baseline; a local polling reproduction still misses changes. Increasing the test deadline cannot recover an event that was never emitted.
+
+**Mock HMR registration or Include.** Rejected because the test must retain transactional recomposition and last-good-state assertions after activation and parse failures.
+
+## Consequences
+
+The transaction sequence retains every semantic assertion and removes fixed change-throttle sleeps. Independent concurrent processes exercise isolation, and a forced setup failure verifies watcher closure and factory restoration before the next case. Native watcher failures remain visible in their owning tests and require their own diagnosis.

+# Agent Note: 用户 patch 事务控制文件系统事件投递
+
+Status: implemented
+
+[English](2026-09-09-user-patch-hmr-test-delivery.md) | 中文
+
+## 问题
+
+[macOS Sandbox 运行](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34238200206/job/102101292119) 在等待首次用户 patch 新增时超时。本地并发复现表明，没有文件系统通知到达 HMR。轮询变体也会遗漏后续修改，此时 HMR 没有待执行的刷新。这些失败阻止事务断言执行其负责验证的解析、激活与回滚行为。
+
+## 决策
+
+[用户 patch 事务测试](../../../../packages/boot/app-boot/tests/user-patches.spec.ts) 写入真实 patch 文件，并通过不持有原生监听句柄的 Chokidar watcher 投递 add、change 和 unlink 事件。HMR 注册、刷新串行化、Include 重组、插件激活、失败广播、回滚与恢复仍使用真实实现。即使初始化在进入局部清理块前失败，夹具也会恢复 watcher 工厂并销毁 Context。
+
+独立的 [HMR 配置测试](../../../../packages/boot/app-boot/tests/hmr-config.spec.ts) 负责原生通知投递，包括 add/change/unlink、初始不存在的父目录和文件系统别名。事务测试不验证操作系统的投递保证。
+
+## 考虑过的替代方案
+
+**每个事务断言都使用原生通知。** 不采用，因为这会让每次解析器与激活状态转换都重复依赖原生投递。事件缺失会掩盖下游究竟哪个行为出现问题。
+
+**轮询与固定等待。** 不采用，因为两者都不能确认下一次修改已经投递。Chokidar 就绪状态不暴露 Node 异步初始轮询基线的完成时刻；本地轮询复现仍会遗漏修改。延长测试期限无法恢复从未发出的事件。
+
+**Mock HMR 注册或 Include。** 不采用，因为测试必须保留事务重组，以及激活和解析失败后的最后有效状态断言。
+
+## 影响
+
+事务序列保留所有语义断言，并移除固定的 change 节流等待。独立并发进程验证隔离性，强制初始化失败则验证 watcher 在下一用例前关闭、工厂在下一用例前恢复。原生 watcher 失败仍在其所属测试中可见，需要单独诊断。

The case retains its 15-second test limit and 30-second wall ceiling, registers Context and reply-timer cleanup, and leaves the hot-loop, decoy-dispatch, wall-ceiling, and abort controls at their existing limits. Production budgets remain unchanged.

 A small untimed fixture prerequisite verifies current migration, message preservation, immutable V0 bytes, and successor reopen. Worker failures retain the first and last ten stderr lines, or fatal heap diagnostics, so setup rejection remains distinguishable from a budget breach. The timed performance cases do not duplicate semantic assertions owned by functional tests; it requires only that the target call completes and reaches its measured endpoint. The Client-fold benchmark continues to use the real `ConversationNodeAssembler` and every Chat Definition, and requires both the large window's absolute time and its scaling relative to the small window to remain below fixed budgets.
 
-Budgets are calibrated per measured endpoint. Two repeated Node 24.19 x64 CI runs differ by at most 5.2% in their medians; their CPU-heavy wall times are 1.95–2.06× the Node 24.18 arm64 reference run. Except for current-generation `open`, source constants record expected reference-machine durations; `ciTimeBudget()` multiplies them by the measured 2× CI time scale and 1.25× variance headroom. Current-generation `open` uses a directly measured standard-runner expectation of 50 ms with only the 1.25× headroom, rounded up to a 63 ms budget. The retained-heap and Client-fold scaling budgets use only the 1.25× headroom because neither is a wall-clock duration. The 128 MB completion check remains an independent transient-allocation limit. The resulting first-open time limits, constrained-heap checks, and Client-fold limits all reject the known regressions. Pre-stack commit `0d7ea53743e273930a31e9e2b6ca682f21dd4ca5` is the fixed calibration and review reference; CI does not check out or execute the historical repository. Budgets are reviewed source constants and have no environment-variable override.

Except for current-generation `open` and first-open Agent resume, source constants record expected reference-machine durations; `ciTimeBudget()` multiplies them by the measured 2× CI time scale and 1.25× variance headroom. Current-generation `open` uses a directly measured standard-runner expectation of 50 ms with only the 1.25× headroom, rounded up to a 63 ms budget. First-open Agent resume uses a reviewed 562 ms hosted limit. The retained-heap and Client-fold scaling budgets use only the 1.25× headroom because neither is a wall-clock duration. The 128 MB completion check remains an independent transient-allocation limit. The resulting first-open time limits, constrained-heap checks, and Client-fold limits all reject the known regressions. Pre-stack commit `0d7ea53743e273930a31e9e2b6ca682f21dd4ca5` is the fixed calibration and review reference; CI does not check out or execute the historical repository. Budgets are reviewed source constants and have no environment-variable override.

 The [standard two-CPU run](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34023970384/job/101461539961) at `ca3ffe95dac2c55eefeb16ed9b61067bbd19ee90` uses Node 24.20.0 x64 and Ubuntu image `20260831.293.1`. Its five current-generation `open` samples are 49.2, 47.4, 49.1, 48.6, and 48.1 ms: median 48.6 ms, maximum 49.2 ms. The rounded 50 ms CI expectation gives a 63 ms limit without reapplying the 2× machine scale. The log identifies two available CPUs but not their model; it does not isolate hardware from the Node-version change. This is endpoint-specific runner calibration, not evidence of an application optimization or a new reference-machine measurement. Every other benchmark passes its existing budget. Deterministic controls reject the observed median at the historical 30 ms limit, accept it at 63 ms, reject a synthetic 75 ms reopen median, and reject a synthetic 4,000 ms first-open duration at its unchanged 550 ms limit. These controls verify budget enforcement, not a measured new regression.
 
-A cold-verifier packaging change removes runtime workspace-module loading without changing these budgets or the measured endpoint. On macOS arm64, Node 24.18.0, the same 127,400-event fixture at `ac48359b195558806ee5a2286697074fd1a52815` takes 164.2, 162.4, 159.7, 149.3, and 167.7 ms for first writable resume (median 162.4 ms). Bundling the verifier through the workspace build gives 119.8, 120.9, 121.9, 122.3, and 121.8 ms (median 121.8 ms, 25% lower). Retained heap stays at 5.4 MB; median peak RSS changes from 144.9 to 143.7 MB. Reopen medians are 27.5 and 27.1 ms, and all 16 Session cases, including the 128 MB completion checks, pass. A CPU profile attributes part of the old verifier cost to module resolution and compilation. The isolated-package built-worker test fails on the original worker because its workspace imports cannot resolve, and passes with the bundled worker, including rejection of an incorrect event count. These local results do not establish Linux runner timing; the existing 450 ms CI gate remains the acceptance check.

The code-equivalent [preceding run](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34263062688/job/102185561214) reports a 436.2 ms median; only the bilingual request-history README and its pairing record differ between those heads. The reviewed ceiling is 562 ms, `floor(450 × 1.25)`, a 24.89% increase that leaves 23.4% above the observed 455.4 ms median. Five fresh M4 Pro / Node 24.19 samples span 150.07–158.22 ms with a 152.57 ms median. A bounded main-thread profile identifies no obvious small optimization; it excludes verifier-thread CPU and does not establish the cause of hosted variation. Controls reject the recorded median at 450 ms, accept it at 562 ms, and reject 600 ms. The bundled-verifier improvement, workload, other time budgets, shared scaling, and memory limits remain intact.

 Interrogation is keyed by **settings namespace**, not by provider route:
 
 - `ctx.llm.registerModelDiscovery(settingsNs, discover)` lets an adapter plugin offer to interrogate endpoints for the namespace it owns, and `ctx.llm.discoverModels(settingsNs, request)` asks. There is no way to enumerate which namespaces registered: a surface that cannot interrogate learns it from the refusal, and a list nothing consumed would be a required wire field doing nothing. The namespace is the right key because a configuration surface already holds it from the configurable-provider directory, and because a provider being added has no route to name.
-- `LlmModelDiscoveryRequest` carries the draft — an optional `provider`, an optional `baseURL`, an optional `api`, an optional `apiKey`, and a signal — and needs at least one of `provider` or `baseURL` to have anything to answer about. `provider` exists because a route the adapter already describes is answered from its own registry with no network call at all; only a route it does not describe reaches an endpoint. Nothing in this path writes settings or credentials. A named configured route reads its stored credential and deployment-owned profile `headers` inside the Host: the credential is write-only and the curated Models page does not edit headers, so neither can be reconstructed from that page's draft. The typed key wins over the stored credential, while the profile headers still accompany the request.

The custom-provider card parses a non-empty `baseURL` and permits only HTTP or HTTPS before it calls this operation or writes the profile. Nothing in this path writes settings or credentials. A named configured route reads its stored credential and deployment-owned profile `headers` inside the Host: the credential is write-only and the curated Models page does not edit headers, so neither can be reconstructed from that page's draft. The typed key wins over the stored credential, while the profile headers still accompany the request.
 - `LlmDiscoveredModel` makes every field but `id` optional, because most listings disclose an id and nothing else. The reply is candidates, not a catalog: a surface adopting one still owes the capacities the adapter requires.
 - `llm.discoverModels` carries the same draft over the wire. Its `apiKey` is the third and last payload on which a secret may ride, alongside `settings.update`/`mutate` and `credentials.set`, and it is never stored or echoed back. It does ride the client's outgoing envelope like every other secret-bearing payload, where a `subscribeEnvelopes()` observer can see it; redacting that tap is a configuration-plane-wide change, not this method's to make alone. Connection authenticates the method with the complete Host API: it makes the host issue a GET to a caller-chosen URL and reports the outcome, which an anonymous caller must not receive. Every refusal 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.

-A person adding a gateway can ask it what it serves instead of hunting through its documentation, and the answer arrives as candidates they choose from rather than as configuration written behind their back.

The seam gained a registry that is deliberately small: one offer per namespace, no storage, no lifecycle beyond the fiber.
+A person adding a gateway can ask it what it serves instead of hunting through its documentation, and the answer arrives as candidates they choose from rather than as configuration written behind their back. A missing scheme, unsupported scheme, or malformed URL fails on the field without a Remote call; localhost, IPv4 and IPv6 literals, and custom ports remain valid. Provider and network failures remain distinct interrogation results. When an endpoint discloses richer metadata, adopting a candidate fills its id, name, context window, and output-token cap into the editable Web row. Search preserves hidden selections, selecting all adds the visible results, and deselecting all clears every result so a filtered picker cannot submit hidden models accidentally. An already-configured enterprise gateway uses the same deployment headers and Harness `User-Agent` for interrogation and model requests without adding a header injection field to the browser protocol. The seam gained a registry that is deliberately small: one offer per namespace, no storage, no lifecycle beyond the fiber.
 
 What it costs: the wire gained a third secret-carrying payload, so the configuration plane's write-only surface is now three methods rather than two. Discovery coverage remains protocol-shaped rather than provider-shaped, and an endpoint using an unsupported request contract must be filled in by hand. Because nothing re-runs the question, a model list is still only as current as its last edit; that is the same trade the layer below made deliberately.

 询问以 **settings namespace** 为键，而不是提供方路由：
 
 - `ctx.llm.registerModelDiscovery(settingsNs, discover)` 让适配器插件为自己拥有的 namespace 提供「询问端点」的能力，`ctx.llm.discoverModels(settingsNs, request)` 发起询问。没有任何办法枚举哪些 namespace 注册过：询问不了的界面会从那句拒绝里知道，而一份无人消费的列表只会变成一个什么都不做的必填协议字段。以 namespace 为键是对的，因为配置界面已经从可配置提供方目录里拿到了它，也因为正在新增的提供方没有路由可点名。

 代价是：协议层多了第三个承载机密的载荷，配置面的只写接口从两个方法变成三个。发现覆盖范围仍按协议而非按提供方划分，使用不受支持请求约定的端点仍须手工填写。由于没有任何环节会重跑该询问，模型列表的新鲜度依旧只到最近一次编辑为止；这与下层刻意做出的取舍是同一个。

 ### Controls and icons
 
-The catalog above lists what each export is for; this section covers the behavior that props alone do not show. The `ic_ds_*` icon set and `FishLogo`/`BrandWordmark` marks fill brand and inline-icon slots. `LinkIcon` draws the leading category glyph for clickable artifact links — globe, folder, code, image, document, or plain paper, all riding `currentColor` — and `classifyLinkPath` derives a file path's category from its extension. `ConnectionIndicator` renders a warning-colored disconnected action, a connecting label whose one-to-three dots advance every 500ms independently of retry timing, or a success-colored recovered status. Hover or keyboard focus shows only the reconnect action label, including while the connecting dots animate. Every state reserves the widest supplied label and uses fixed icon and text columns, so copy changes do not move or resize the control. Its owner supplies visibility, the recovery hold, localized labels, and the immediate-reconnect callback; the primitive uses no native title tooltip. `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. `Toast` holds for the window its owner names through `holdMs`, because how long a banner has to stay depends on how much there is to read; the same value drives its unmount timer and the stylesheet's fade delay, so the two cannot disagree. `rankByName` is the `/` menu's shared candidate ranker for the command and skill sources: the query must be a case-insensitive ordered subsequence of the name; prefix hits rank first, then alignment score, then source order.

Subject: [PATCH 036/164] feat(dockkit): refine strip and chip presentation,
 close policy, and room reading

Chip capsules with scroll fades and live titles, drop-zone hint cards, the
canCloseTab control policy with the quiet lone chip and self-dismissing empty
menu, and a room reading that stays independent of hidden split controls.

+## Problem
+
+The dockkit room rule measures each pane's tab strip after every commit to decide whether an equal split leaves two working halves. With `hideSplitWhenBlocked`, a width-blocked pane unmounts its split control — and the unmount changes the very strip the rule measured: the strip sheds the control's 28px box plus its 4px gap, the fixed part shrinks, and the same pane reads as fitting again. Remounting the control reverses the reading. Across a roughly 32px band of pane widths the two states alternate inside nested layout effects until React stops the update loop (error #185); the slot runtime catches the crash and unmounts the Sidebar's entry while the column still records itself expanded, so neither the panel nor the header's collapsed-only expand button renders. A grip drag on a squeezed viewport sweeps the panel through that band, which presented as the whole sidebar vanishing with no way back in.
+
+## Decision
+
+When the embedder hides blocked split controls, the room rule leaves the split control's footprint out of the strip's fixed part unconditionally, so the reading is the same whether the control is currently mounted or not. [`measurePaneFits`](../../../../packages/client/ui-dockkit/src/components/measure.ts) takes the embedder's `hideSplitWhenBlocked` choice, measures the rendered control's box plus the strip's column gap (`splitControlFootprint`), and passes it as [`PaneMeasure.splitControlWidth`](../../../../packages/client/ui-dockkit/src/engine/geometry.ts), which `halvesFit` subtracts from the fixed part. Excluding the footprint is also correct on its own terms: a half too narrow to split would hide its own control, so the footprint is not part of what a half must carry. Embedders that render blocked controls disabled pass nothing and keep the control in the fixed part, as before.
+
+## Alternatives considered
+
+**Hide only budget-blocked controls, render width-blocked ones disabled.** This is what the code did before `hideSplitAtCapacity` widened into `hideSplitWhenBlocked`: the budget is state-driven and cannot feed back through the measurement. It avoids the loop but forfeits the Sidebar's requested presentation — no disabled split control on panes that cannot split.
+
+**Debounce or freeze re-measurement during oscillation.** Damping hides the instability instead of removing it: the reading would still depend on the control's visibility, settle on an arbitrary one of the two states, and flip on the next resize.
+
+**Measure the control's footprint from a constant.** A hardcoded 32px drifts from the stylesheet; measuring the rendered control and the strip's real `column-gap` keeps the subtraction equal to what the strip actually sheds, which is the exact condition for a stable reading.
+
+## Consequences
+
+The room reading is a fixed point under control visibility, so `hideSplitWhenBlocked` embedders get hidden controls without feedback. Panes near the boundary now read as splittable slightly earlier than a disabled-control embedder would report, because the half being asked about would not carry the control. A [dockkit regression test](../../../../packages/client/ui-dockkit/tests/components.client.spec.tsx) emulates the strip shedding the control's footprint and fails with React's update-depth error on the unfixed code; a [Sidebar browser case](../../../../apps/web/tests/sidebar-right.e2e.ts) drags the panel grip past both clamps on a squeezed viewport and asserts the panel, its grip, and a clean console survive, because the crash surfaces only as a console error the scaffold tripwire does not watch.

+## Problem
+
+dockkit 的空间规则在每次 commit 后测量各 pane 的标签条，判断等分后的两半是否仍可用。开启 `hideSplitWhenBlocked` 时，宽度不足的 pane 会卸载自己的分屏控件——而这次卸载恰恰改变了规则所测量的标签条：标签条少了控件的 28px 盒子加 4px 间距，固定部分随之变小，同一个 pane 又被读成"够宽"。控件重新挂载后读数再次反转。在约 32px 的 pane 宽度区间内，两种状态在嵌套 layout effect 中来回切换，直到 React 中止更新循环（错误 #185）；slot 运行时捕获崩溃后卸载 Sidebar 的条目，而列状态仍记录为展开，于是面板和 header 上仅折叠时显示的展开按钮都不再渲染。在收窄的视口上拖动把手会让面板扫过该区间，表现为整个侧栏消失且无法再打开。
+
+## Decision
+
+当嵌入方选择隐藏被阻止的分屏控件时，空间规则无条件将分屏控件的占位排除在标签条固定部分之外，使读数与控件当前是否挂载无关。[`measurePaneFits`](../../../../packages/client/ui-dockkit/src/components/measure.ts) 接收嵌入方的 `hideSplitWhenBlocked` 选择，测量已渲染控件的盒子加标签条的列间距（`splitControlFootprint`），并作为 [`PaneMeasure.splitControlWidth`](../../../../packages/client/ui-dockkit/src/engine/geometry.ts) 传入，由 `halvesFit` 从固定部分中减去。排除该占位本身也是正确的：窄到无法分屏的一半会隐藏自己的控件，所以这份占位并不属于一半必须承载的内容。将被阻止控件渲染为禁用态的嵌入方不传该值，控件照旧计入固定部分。
+
+## Alternatives considered
+
+**只隐藏预算受限的控件，宽度受限的渲染为禁用态。** 这是 `hideSplitAtCapacity` 扩展为 `hideSplitWhenBlocked` 之前的做法：预算由状态驱动，不会经测量反馈回来。它避免了循环，但放弃了 Sidebar 想要的呈现——无法分屏的 pane 上不出现禁用的分屏控件。
+
+**在振荡期间对重新测量做防抖或冻结。** 阻尼只是掩盖不稳定而非消除它：读数仍依赖控件的可见性，会任意停在两种状态之一，并在下次 resize 时再次翻转。
+
+**用常量表示控件占位。** 硬编码的 32px 会与样式表漂移；测量实际渲染的控件和标签条真实的 `column-gap`，才能保证减去的量恰好等于标签条实际卸下的量，这正是读数稳定的确切条件。
+
+## Consequences
+
+空间读数在控件可见性变化下是不动点，`hideSplitWhenBlocked` 的嵌入方获得隐藏控件的呈现且无反馈循环。临界宽度附近的 pane 会比禁用态嵌入方的报告稍早读成可分屏，因为被询问的那一半不会承载控件。[dockkit 回归测试](../../../../packages/client/ui-dockkit/tests/components.client.spec.tsx) 模拟标签条卸下控件占位的反馈，在未修复的代码上以 React 更新深度错误失败；[Sidebar 浏览器用例](../../../../apps/web/tests/sidebar-right.e2e.ts) 在收窄视口上把面板把手拖过两侧钳位，断言面板、把手与干净的 console 均存活——崩溃只以 console error 形式出现，而脚手架的 tripwire 不监听它。

Hiding the add control moves nothing else in the strip, and a withheld close moves nothing in the chip — the close control paints over the title's end rather than beside it. A pane's lone chip whose close is withheld draws quiet — no capsule, no hover fill — since there is nothing to select against and nothing to do to it. The kit adds one policy of its own, the room rule below, which disables a pane's split control with `splitPaneNarrow`; `onRoom(fits)` reports its readings so an embedder splitting programmatically can honour the same rule.
 
-`dropZones="horizontal"` offers two half-pane hints; once budget or width forbids another split, the whole body accepts a move. `minPaneFraction` sets the preview minimum, and `planResizeSplit` accepts the same minimum for the committed operation. The Sidebar uses 0.2 and enforces two panes in its own store. The generic engine retains its tree and other split directions. `hideSplitAtCapacity` hides the split control at the pane budget; its default is false, and a width-blocked control remains disabled.
+`dropZones="horizontal"` offers two half-pane hints; once budget or width forbids another split, the whole body accepts a move. A hint is a dashed card inset 8px inside its region, showing the zone's glyph and `labels.dropZone[zone]`; the card under the pointer takes the accent and its neighbour stays a quiet outline. `minPaneFraction` sets the preview minimum, and `planResizeSplit` accepts the same minimum for the committed operation. The Sidebar uses 0.2 and enforces two panes in its own store. The generic engine retains its tree and other split directions. `hideSplitWhenBlocked` hides a blocked split control — pane budget spent or pane too narrow — instead of rendering it disabled; its default is false.
 
 A tab's `kind` is an opaque string. Seeded tabs are factories (`DockControllerOptions`), so what a fresh pane contains is the embedder's decision, not this package's. Content identity is the pair (`kind`, `contentId`): `findContentTab(state, contentId, kind?)` finds the tab showing it anywhere and `findPaneContentTab(state, paneId, contentId, kind?)` within one pane, and `planOpenContent` focuses that tab instead of opening another unless told `revealIfOpened: false`; an explicit `index` seats a new tab at a strip slot rather than at the end.

 These are not stylistic; each one fixes a defect found in a real browser.
 
 - **Capture the pointer** when a gesture starts. Without it any scroll container the pointer crosses can claim the gesture, which the browser reports as a cancelled pointer and an abandoned drag. Capture is hardening — the window listeners carry the gesture either way, so an environment without the API still works.
-- **The chips give way; the strip's end controls never do.** The chip box is the strip's one shrinking part (`flex: 0 1 auto; min-width: 0; overflow: hidden`); the add, split, and chrome controls are `flex: none`, so they keep their width and place in any pane at least as wide as they are (about 130px with the chrome, 72px without). The surface's `min-width: 0` and the pane's `overflow: hidden` stop a body's longest unwrapped line from widening the pane past its box, which is what carried the controls and the body's scrollbar off-screen.
-- **The chip box is not a scroll container.** A horizontal scroller claims press-and-move for itself; tabs shrink, ellipsize, and then clip instead.
-- **A split needs room for two working halves.** A pane splits into equal halves, so each half must hold what cannot shrink: the strip's fixed part — measured as the strip's width minus the chip box and the fill, which is the padding, the gaps, and every control that pane draws (its own chrome included, so the top-right pane asks more) — plus one chip at its minimum — `.tab` declares `min-width: 44px` on a content-box, so its footprint is 44px plus 10px + 5px of padding, 59px, read from a rendered chip's computed style (the stylesheet figure when none can be read); the divider between the halves takes its rendered thickness (4px). A column split, which only an edge drop makes, needs each half to hold the strip (36px) plus a 48px body: one 13px secondary line at 1.6 line-height inside the body's 12px padding. `halvesFit` in `geometry.ts` is the arithmetic; `measure.ts` reads the rectangles after every commit and whenever the surface resizes, because the layout state carries fractions, never pixels, and the engine's planners stay that way. A pane without room keeps its split control, disabled with `splitPaneNarrow`, and offers no edge drop zone for that axis (the release is then not a move). A pane the user narrows afterwards — a divider or the embedder's column dragged — keeps its size: the rule only decides its next split.
+- **The chips give way; the strip's end controls never do.** The chip box is the strip's one shrinking part (`flex: 0 1 auto; min-width: 0; overflow-x: auto`): chips shrink down to an 80px floor and then scroll on the wheel with no scrollbar drawn, and the box fades its chips out over 24px at each side that hides some (`data-dockkit-strip-scroll`, written from the box's scroll reading after each commit, scroll, and resize). Whenever the active tab or the row of chips changes, the box scrolls so the active chip stands clear of the fade band; a chip already in view moves nothing. A chip's title is never ellipsized: `TabTitle` reads its text against its box and sets `data-dockkit-tab-clipped` while the text is wider, which fades the text out over its last 16px. A chip's close control shows while the chip is active, hovered, or holds focus, over the title's last 14px, which fade under it, so the chip is the same width either way. The two slots beside the active chip draw no hairline, so the filled capsule stands between bare chips. The add, split, and chrome controls are `flex: none`, so they keep their width and place in any pane at least as wide as they are (about 130px with the chrome, 72px without). The surface's `min-width: 0` and the pane's `overflow: hidden` stop a body's longest unwrapped line from widening the pane past its box, which is what carried the controls and the body's scrollbar off-screen.
+- **The chip box scrolls, but never claims a gesture.** A horizontal scroller would take press-and-move for itself and cancel the pointer; the box, the chips, and the strip set `touch-action: none` and the gesture captures the pointer, so a press-and-move on a chip is a drag and only the wheel scrolls the box.
+- **A split needs room for two working halves.** A pane splits into equal halves, so each half must hold what cannot shrink: the strip's fixed part — measured as the strip's width minus the chip box and the fill, which is the padding, the gaps, and every control that pane draws (its own chrome included, so the top-right pane asks more) — plus one chip at its minimum — `.tab` declares `min-width: 80px` on a content-box, so its footprint is 80px plus 10px + 10px of padding, 100px, read from a rendered chip's computed style (the stylesheet figure when none can be read); the divider between the halves takes its rendered thickness (0 — its hairline paints over the seam without taking layout room, so a body's own rules run unbroken past it). A column split, which only an edge drop makes, needs each half to hold the strip (34px) plus a 48px body: one 13px secondary line at 1.6 line-height inside 12px of the body's own insets — the pane body itself is unpadded, so a tab's body reaches the strip's bottom edge and the pane's edges and draws its own. `halvesFit` in `geometry.ts` is the arithmetic; `measure.ts` reads the rectangles after every commit and whenever the surface resizes, because the layout state carries fractions, never pixels, and the engine's planners stay that way. A pane without room keeps its split control, disabled with `splitPaneNarrow` (hidden instead under `hideSplitWhenBlocked`), and offers no edge drop zone for that axis (the release is then not a move). Under `hideSplitWhenBlocked` the split control's own footprint — its box plus the strip's gap — is left out of the fixed part: hiding the control sheds exactly that footprint from the strip, so a reading that counted it would flip with the control's visibility and re-render forever; leaving it out is also what the half being asked about would carry, since a half too narrow to split hides its own control. A pane the user narrows afterwards — a divider or the embedder's column dragged — keeps its size: the rule only decides its next split.
 - **Focus lands on click, not on press.** A state change between `pointerdown` and the first `pointermove` rebuilds the pressed subtree, and a replaced element cancels the pointer. It also keeps a drag from recording a redundant focus operation first. Clicks on the chips, the strip's controls, and the embedder's chrome stop at the strip: the intent each reports already decides the active pane, or is the embedder's own, so the pane's click-to-focus records nothing extra. A floating panel's grip and corner report through their gesture the same way — a press released in place is a click that raises the panel, and a drag records only the move or resize, whose operation raises it — while a press on the panel's body raises it directly. A click on the pane that is active already, a click or key on that pane's selected chip, or a press on the panel that is active and on top already, changes nothing and records nothing.
 - **A control nested inside a draggable chip stops its own press.** Otherwise the press starts a drag, captures the pointer, and the nested control's click never lands.
-- **Emphasis takes the platform's accent, never `--dsw-alias-brand-primary`.** This platform binds `brand-primary` to its near-black (light) or near-white (dark) foreground, so a hovered divider, the drop caret, and the drop-zone hint use `--dsw-alias-brand-primary-new-colorprimary-new-color`, as the trajectory views do. A floating panel's border is the same `--dsw-alias-border-l2` hairline whether it is active or not: the active panel is already on top and casts the shadow; a darker frame around it read as a defect.

 ## Build shape
 
-Its static ESM retains third-party imports for the Web shell's Vite build; independent consumers supply its development dependencies ([dependency rules](../AGENTS.md#dependency-declaration)).
-
 The package is statically linked: tsdown's `staticLinked` preset emits one browser ESM bundle at `lib/index.js` (every bare specifier stays an import, sourcemaps chain to the sources) and ships the stylesheet under `lib/` at its `src`-relative path, and the Web shell resolves the package name and bundles that artifact itself, so vite stays the only owner of class hashing. One consequence is load-bearing — the kit keeps **one** stylesheet, `dockkit.module.css`, because a consumer de-duplicates injected sheets by file name and a collision would drop one silently.

Subject: [PATCH 037/164] feat(sidebar): last-tab close rules and collapsed
 expand button

The lone guide tab withholds its close and menu, any other lone tab closes
together with the column, and the expand button renders only while collapsed
so the corner seat costs the header nothing.

The settle step is the product's rule: a docked pane whose last tab is closed, moved out, or floated is merged away, and when only the root pane remains and it is empty, the guide tab is reseeded — there is always at least one tab and never an empty pane, so no pane-closing gesture exists.

 **Inline the kit through `packages/util` and the `INLINE_SAFE` list.** A build probe showed it works, but the util build chain has no CSS pipeline and the kit ships a stylesheet; the static-linked client package (the `ui-primitives` precedent) was chosen knowing that changing the kit means rebuilding the shell and reloading.

 - A pane holds at most one guide tab: a second one cannot be added, opened, duplicated, or moved in; the guide's uniqueness is per pane, so a split still seeds its new pane with a guide.
 - A pane may split only when each equal half can still hold what cannot shrink: the strip's fixed controls (its width minus the chip box and the fill, so the top-right pane's chrome counts on the half that hosts it) plus one chip at its minimum, measured in the component layer after every commit and on resize. Otherwise the split control stays, disabled with its own copy, the matching edge drop zones are withheld, and panes the user narrows keep their size; the product permits at most two horizontal panes, regardless of widening or divider movement.
 - The Sidebar panel never moves when the presentation switches, and its slide is the same in both presentations; the conversation is the only thing that animates on a switch. A hidden panel keeps its tabs mounted, so a preview survives a collapse.

+A guide with one registered entry adds a click without offering a choice.
 
 ## Decision
 
 The Sidebar selects each default page from the registered guide-entry list. Exactly one entry opens that entry's page; zero or multiple entries open the guide. Resource viewers without guide entries do not affect this count. Explicitly adding a guide always opens a guide, and each pane holds at most one.
 
-A single-entry default is protected from explicit close for its record lifetime. Every pane's final tab is also protected; other tabs can close. The Sidebar stores protected record IDs and shares one close predicate between its store actions and docking controls. The generic docking kit accepts a presentation callback and has no file-browser or guide policy. Moving tabs still settles empty panes, and layout state remains memory-only.
+The [last-tab close rule](2026-09-08-sidebar-last-tab-close-rules.md) owns close protection: the sole docked guide remains open, while any other sole tab closes together with the column.

+# Agent Note: Last-tab close rules on the Sidebar's docked surface
+
+Status: implemented
+
+English | [中文](2026-09-08-sidebar-last-tab-close-rules.zh.md)
+
+## Problem
+
+The settle planner guarantees the docked surface is never empty: closing the last tab reseeds the current default page. That guarantee made the last tab's close control a dead end in both directions. Closing the guide standing alone put the same guide straight back — a control that does nothing. Closing any other lone tab left the user with a column showing only the default page — after "close the last thing", an expanded panel with nothing in it is not what the gesture meant. The guide's chip also drew a hover capsule and a context menu whose only item was that no-op close.
+
+## Decision
+
+The docked surface's last tab carries one rule, decided in the Sidebar store's `closeTab` and mirrored to the kit through a new `canCloseTab(tabId)` control-policy prop (joining `canSplit` and `canAddTab`): the guide standing as the only docked tab is unclosable — no chip close control, no menu close item, and a programmatic close records nothing; any other lone tab closes together with the column in one history entry, so the settle planner prepares the current default page for the next expansion. `soleDockedTab(state, tabId)` in [stores.ts](../../../../packages/client/ui-sidebar-right/src/client/stores.ts) names the condition; floating panels take no part in it. Per the packages rule "enforce a decision in the operation that makes it", the store's `closeTab` is the enforcement and `canCloseTab` only mirrors it into the chrome. This rule supersedes the close-protection part of [the default-page decision](2026-09-08-sidebar-default-pages.md); its selection rule remains active.
+
+Two kit-side presentation rules complete it in [TabPanel.tsx](../../../../packages/client/ui-dockkit/src/components/TabPanel.tsx) and [TabMenu.tsx](../../../../packages/client/ui-dockkit/src/components/TabMenu.tsx): a pane's lone chip whose close is withheld draws quiet — no capsule, no hover fill — since there is nothing to select against and nothing to do to it; and a menu that would hold no item at all dismisses itself before the first paint, so a secondary press on such a chip shows nothing rather than an empty box.
+
+## Alternatives considered
+
+**Keep the guide closable and let settle reseed it.** The visible result is a close control that does nothing; the control lies about what a press will do.
+
+**Hide the close in the Sidebar's renderer instead of a kit prop.** The kit draws the chip's close and the menu's close item, so the embedder cannot withhold them without a seam; a CSS override would leave the menu item live and split one decision across two owners.
+
+**Collapse the column from the kit when the last tab closes.** The kit has no concept of the column or its expansion; the collapse is the embedder's intent, recorded by the store alongside the close in the same entry.
+
+## Consequences
+
+`canCloseTab` is a third control-policy prop every embedder may set; leaving it out keeps every tab closable. The quiet-chip and empty-menu rules are unconditional kit behavior keyed on the same policy, so any embedder withholding a lone tab's close gets the same presentation. Reopening the column after a lone-tab close shows the default page selected from the current guide entries. Kit specs cover the withheld control, the quiet chip, and the self-dismissing menu; Sidebar unit specs cover `closeTab`'s refusal and the close-with-column entry; a [browser case](../../../../apps/web/tests/sidebar-right.e2e.ts) walks the whole rule on the rendered panel.

+# Agent Note：Sidebar 停靠面最后一个 tab 的关闭规则
+
+Status: implemented
+
+[English](2026-09-08-sidebar-last-tab-close-rules.md) | 中文
+
+## 问题
+
+settle planner 保证停靠面永不为空：关掉最后一个 tab 会重新播种当前默认页。这条保证让最后一个 tab 的关闭控件在两个方向上都走进死胡同。独自留下的引导页被关闭后，同一个引导页立刻回来——一个什么也不做的控件。任何其它 tab 独自留下时被关闭，用户面前只剩一列只显示默认页的面板——在「关掉最后一个东西」之后，一块展开着却空无内容的面板不是这个手势的本意。引导页的 chip 还画着悬停胶囊，右键菜单里唯一的条目就是那个无效的关闭。
+
+## 决定
+
+停靠面的最后一个 tab 带一条规则，由 Sidebar store 的 `closeTab` 决定，并经新的控制策略 prop `canCloseTab(tabId)`（与 `canSplit`、`canAddTab` 并列）镜像给套件：作为唯一停靠 tab 的引导页不可关闭——chip 上没有关闭控件，菜单里没有关闭项，编程式关闭什么都不记录；任何其它 tab 独自留下时，关闭会连同整列一起收起，记为一条历史，于是 settle planner 为下次展开准备当前默认页。[stores.ts](../../../../packages/client/ui-sidebar-right/src/client/stores.ts) 里的 `soleDockedTab(state, tabId)` 命名这个条件；浮动面板不参与。按照 packages 规则「在做出决定的操作里执行它」，store 的 `closeTab` 是执行点，`canCloseTab` 只是把它镜像到界面。本规则取代[默认页决策](2026-09-08-sidebar-default-pages.zh.md)中的关闭保护部分；其默认页选择规则仍然有效。
+
+两条套件侧的呈现规则在 [TabPanel.tsx](../../../../packages/client/ui-dockkit/src/components/TabPanel.tsx) 与 [TabMenu.tsx](../../../../packages/client/ui-dockkit/src/components/TabMenu.tsx) 里补全它：某格仅剩的一个 chip 在关闭被收起时画成安静样式——没有胶囊底色，没有悬停填充——因为既没有别的 tab 可供选择，也没有任何可对它做的事；一个连一项都没有的菜单在首次绘制前自行消失，于是对这样的 chip 次键按下什么都不显示，而不是画一个空框。
+
+## 考虑过的替代方案
+
+**让引导页保持可关闭，由 settle 重新播种。** 可见的结果是一个什么也不做的关闭控件；这个控件在按下会发生什么这件事上撒谎。
+
+**在 Sidebar 的渲染器里藏掉关闭，而不加套件 prop。** chip 的关闭控件与菜单的关闭项都由套件绘制，没有接缝嵌入方就无法收起它们；CSS 覆盖会留下仍然生效的菜单项，把一个决定拆给两个所有者。
+
+**由套件在最后一个 tab 关闭时收起整列。** 套件没有「列」或「展开」的概念；收起是嵌入方的意图，由 store 在同一条历史里与关闭一并记录。
+
+## 后果
+
+`canCloseTab` 成为每个嵌入方都可设置的第三个控制策略 prop；不设置时每个 tab 都可关闭。安静 chip 与空菜单两条规则是套件的无条件行为，键在同一策略上，任何收起了独 tab 关闭的嵌入方都得到同样的呈现。独 tab 关闭后重新展开的列显示根据当前引导入口选出的默认页。套件 spec 覆盖收起的控件、安静 chip 与自行消失的菜单；Sidebar 单元 spec 覆盖 `closeTab` 的拒绝与「关闭连带整列」的历史条目；一个[浏览器用例](../../../../apps/web/tests/sidebar-right.e2e.ts)在渲染出的面板上走完整条规则。

+The docked surface's last tab carries one more rule, decided in the store's `closeTab` and mirrored to the kit through `canCloseTab`: the guide standing as the only docked tab draws no close control and no menu close item — its chip sits quiet, and with no extension item contributed a secondary press opens no menu — and a programmatic close of it records nothing; any other tab standing alone closes together with the column in one entry — the settle planner reseeds the current default page for the next expansion. Floating panels take no part in the rule: they render whether or not the column is expanded, and their tabs close freely.

Exactly one entry opens its page directly (Files in the shipped composition); zero or multiple entries open the guide. Each single-entry default remains non-closable when other tabs are added.

The strip's add control is drawn only while its pane holds none and opens one there with `openTab('guide', { paneId, revealIfOpened: false })`, so a guide in another pane does not capture the click; opening the guide into a pane that already has one focuses it instead; a guide dragged, dropped, or docked into such a pane merges into it — the arriving guide closes and the pane's own is focused; `duplicateTab` on the guide records nothing. A split or an emptied root pane uses the same default-page rule, one tab per new pane. A plain `openTab('guide')` keeps the tree-wide reveal every open has. The product allows two horizontal panes, initially equal, with divider ratios limited to 20%–80%.

 ## What it registers
 
-- **The type** — `ctx.sidebarRightTabs.register(...)` with id `@deepseek-ai/dsh-client-ui-sidebar-documentpreview` (this implementation's identity in the tab system, and the key its body registers under), kind `text`, pattern `dsh-resource://file/**`, band `fallback`. `canOpen` accepts only Session addresses, whose paths may be relative or absolute; bare `absolute` addresses are not claimed. A type registered at the `extension` or `builtin` band for a narrower pattern (say `*.png`) takes those addresses; other supported files land here. The whole address is the content identity, so two files with one name in different directories, or one path under two sessions, are two tabs; the decoded basename is the tab title.
-- **The body** — the keyed `sidebar.right.pane.tab` seat under the type's id. Its fixed header shows the Host's absolute path when available, otherwise the requested path, and a dropdown for matching renderers plus plain text. A wrap toggle appears only when the selected renderer declares `wrap: true`; the per-tab preference starts on. Reload stays in this header, not the Sidebar's tab strip. The shared body below owns document scrolling.

+- **The body** — the keyed `sidebar.right.pane.tab` seat under the type's id. Its fixed header shows the Host's absolute path when available, otherwise the requested path; directories use tertiary label colour, the name uses primary label colour, and a clipped path retains and fades toward its final segment while its tooltip exposes the full value. A dropdown selects among matching renderers and plain text. A wrap toggle appears only when the selected renderer declares `wrap: true`; its glyph describes the mode the click selects, and the per-tab preference starts on. Reload stays in this header, not the Sidebar's tab strip. The shared body below owns document scrolling.
 - **Shared loading and view state**, session-scoped and bucketed by tab id. The store holds accumulated pages or complete bytes, read and observed versions, loading/failure state, renderer choice, scroll offset, wrap, and the answered navigation revision. The ordinary inject face calls Remote readers and writes through declared store actions. Reloads and loading-mode changes retire older requests; the tab's abort signal forgets its state.
 
 Document implementations register metadata with `ctx.documentPreviews.register({ id, extensions, priority, title, loading, wrap? })` and a body under the same `id` in the keyed, Session-scoped `sidebar.right.tab.document` child slot. Own both registrations with effects and wait for the child slot through `ctx.slots.inject`. Bodies receive `resourceAddress`, prepared `content`, `wrap`, and the standard `useTabInfo`/`useResource` hooks; they do not receive a custom resource loader. Metadata declares `loading: 'text-pages'` or `'bytes-complete'`. The registry retains all matching alternatives: `extension` (the default) ranks above `builtin`, then longer suffixes rank first, then registration order. The dropdown preserves a selected implementation while it remains available; removing it selects the next candidate. Builtin bodies use these same registrations.

 The body reads its record, navigation and lifetime through `useTabInfo().tab`. `useResource<'file'>(tab.contentId)` supplies metadata; ordinary inject callbacks supply content reads:
 
 - The resource snapshot contains only `status`, `value`, and `failure`; `value` is `WorkspaceFileStat` metadata. Content reads do not wait for the first metadata frame once the provider is available. Observation failures take precedence over Preview's change notice; neither automatically replaces loaded content.
-- **Text pages** — plain text, Markdown, and code read through an inject callback to `remote.workspaceFiles.read(sessionId, path, { offset }, signal)`. The first mount reads page one; scrolling to the body end or **Load more** requests the next page until `eof`. The owner delivers the accumulated prefix as `{ kind: 'text', text, pages, eof }`, including source offsets and line counts. Markdown and code render that prefix incrementally; they do not render each page as a separate document. A newer-version page past page one restarts from the beginning rather than mixing versions. Failures retain loaded content and offer a retry.

A failure before any content fills the body with the file-type icon, explanation, and retry; a later failure retains loaded content and adds the retry below it.
 - **Complete bytes** — PDF and HTML use an inject callback to `remote.workspaceFiles.readAll(sessionId, path, signal)`. `rpc.ts` decodes the wire base64 into `data: Uint8Array<ArrayBuffer>` for `{ kind: 'bytes', data }`. The Host's `maxFileBytes` cap rejects oversized files rather than truncating them. PDF copies retained bytes before worker transfer, keeping the Preview buffer usable. Bytes stay in transient view state, never persisted layouts or Session JSONL. Loading-mode changes retire previous results.
 - **Reload** — only the current Preview tab rereads through its Remote callbacks, preserving its scroll preference and retiring older requests. Its change notice compares the read version and the observation captured at read start with later `resource.value.version`; an already observed version does not become a new change after refresh. Reads neither refresh shared metadata nor clear another tab's notice.

 - **Finite local HTML dependencies.** Only direct classic `.js` and stylesheet `.css` references are packed. Browser-resolved resources retain browser origin and network restrictions; no runtime file-read bridge is exposed to the iframe.

+- **Package-local wrap glyphs.** `IconWrapFill16` and `IconNowrapFill16` live in `src/client/icons.tsx` until the shared icon set carries them; their props already match the shared icon contract.
 - **Scroll writes are unthrottled.** Every scroll event records its offset in the store; the line blocks are memoized so the resulting re-render hands React the same elements back.

 文档实现在 `ctx.documentPreviews.register({ id, extensions, priority, title, loading, wrap? })` 注册元数据，并以相同 `id` 向 keyed、Session 作用域的子 slot `sidebar.right.tab.document` 注册正文。两处注册都由 effect 持有，通过 `ctx.slots.inject` 等待子 slot。正文接收 `resourceAddress`、准备好的 `content`、`wrap` 和标准 `useTabInfo`/`useResource` 钩子，不接收自定义资源加载器。元数据声明 `loading: 'text-pages'` 或 `'bytes-complete'`。注册表保留所有匹配备选：`extension`（默认）优先于 `builtin`，随后按更长的后缀、再按注册顺序排列。所选实现仍可用时，下拉选择保持不变；移除后选择下一个候选。内置正文也使用相同注册方式。

 ## What it registers
 
 - **The type** — `ctx.sidebarRightTabs.register(...)` with kind `files`, id `@deepseek-ai/dsh-client-ui-sidebar-files`, band `builtin`, no patterns, and one guide entry (order 10, titled from the `sidebarFiles` namespace) that opens the type.
-- **The body** — the keyed `sidebar.right.pane.tab` seat under that id: the tree, with its one control, reload, at the right of its header row.
+- **The body** — the keyed `sidebar.right.pane.tab` seat under that id: a header row under the strip, then the tree. The header row is the document preview's (`ui-sidebar-documentpreview`): the root path, its directories greyed and its last segment in full ink, never ellipsized (a path wider than the row keeps its end and fades its start), with the one control, reload, at its right. The row is copied rather than shared because a plugin bundle shares runtime code only through the platform modules; once the artifact and slot surfaces settle, one copy in `ui-primitives` could serve every pane header.

 ## The tree
 
-The root is the session's working directory, read from `useSessions().byId[sessionId].cwd`, and labelled by `workspaceTitleOf` from `@deepseek-ai/dsh-util-workspace-path`. Every level is keyed by absolute path; a child's path is its parent's joined with the entry name by `/`. A level is listed when it is first expanded, through `remote.workspaceFiles.list(sessionId, absolutePath)` on the `@deepseek-ai/dsh-api-workspace-files` namespace; the adapter keeps the listing's entries and truncation flag and drops its workspace-relative path. Rows are ordered directories first, then by natural, case-insensitive name; dotfiles are shown like any other entry.

 ## Summary
 
-`dsh-session-log-export` lets the Web interface 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. The package owns the Host archive stream, its authenticated Fetch route, and the browser controls and feedback. The browser chooses the download destination. Setup and usage come first; implementation details follow.

Subject: [PATCH 044/164] fix(sidebar): address review feedback on aria names,
 touch hits, and fullscreen close

- Split toggle aria-labels from their tooltips: the sidebar expand/collapse
  buttons announce "Open/Collapse right sidebar" so the two sidebars stay
  distinguishable, and the wrap toggle keeps an invariant "Line wrap" name
  beside aria-pressed while the tooltip keeps the action wording.
- A hidden tab close also takes no pointer events, so a touch press on the
  chip's trailing edge activates the tab instead of closing it; e2e closes
  hover the chip first, the way a reader would.
- Closing the last docked tab in fullscreen hands the mode back to push, so
  the next expand does not give the whole window to the start page.
- The drop scrim mixes from bg-base, not bg-layer-2, which dark mode binds
  to a lighter bluish step than the column beneath it.
- Document the menuitem probe in TabMenuExtras and the strip fade's known
  gap; match the open-in-app split-button comment to the 28px control row.

 ## Decision
 
-The docked surface's last tab carries one rule, decided in the Sidebar store's `closeTab` and mirrored to the kit through a new `canCloseTab(tabId)` control-policy prop (joining `canSplit` and `canAddTab`): the guide standing as the only docked tab is unclosable — no chip close control, no menu close item, and a programmatic close records nothing; any other lone tab closes together with the column in one history entry, so the settle planner prepares the current default page for the next expansion. `soleDockedTab(state, tabId)` in [stores.ts](../../../../packages/client/ui-sidebar-right/src/client/stores.ts) names the condition; floating panels take no part in it. Per the packages rule "enforce a decision in the operation that makes it", the store's `closeTab` is the enforcement and `canCloseTab` only mirrors it into the chrome. This rule supersedes the close-protection part of [the default-page decision](2026-09-08-sidebar-default-pages.md); its selection rule remains active.
+The docked surface's last tab carries one rule, decided in the Sidebar store's `closeTab` and mirrored to the kit through a new `canCloseTab(tabId)` control-policy prop (joining `canSplit` and `canAddTab`): the guide standing as the only docked tab is unclosable — no chip close control, no menu close item, and a programmatic close records nothing; any other lone tab closes together with the column in one history entry, resets fullscreen to push mode, and lets the settle planner prepare the current default page for the next expansion. `soleDockedTab(state, tabId)` in [stores.ts](../../../../packages/client/ui-sidebar-right/src/client/stores.ts) names the condition; floating panels take no part in it.

-Two kit-side presentation rules complete it in [TabPanel.tsx](../../../../packages/client/ui-dockkit/src/components/TabPanel.tsx) and [TabMenu.tsx](../../../../packages/client/ui-dockkit/src/components/TabMenu.tsx): a pane's lone chip whose close is withheld draws quiet — no capsule, no hover fill — since there is nothing to select against and nothing to do to it; and a menu that would hold no item at all dismisses itself before the first paint, so a secondary press on such a chip shows nothing rather than an empty box.

Subject: [PATCH 045/164] test(web): refresh goldens for the sidebar aria
 renames

The expand/collapse and wrap toggles' accessible names diverged from their
tooltips, and the replay harness now normalizes clientTimeZone in recorded
sessions; every golden holding the old names or the literal zone refreshes.

From c73dcecb961bb2f2d48f2a8ec9ac982f2ab3c81e Mon Sep 17 00:00:00 2001
From: Yif <877193178@qq.com>
Date: Wed, 9 Sep 2026 00:26:36 +0800
Subject: [PATCH 046/164] fix(textpreview): say a stat-and-read failure once
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A file whose stat and first page both fail — outside the workspace, gone —
showed the same line twice: the metadata bar above an identical centred body
failure. The bar now stands only over pages already loaded, and the centred
retry runs the full reload so one press clears both halves.

-# Agent Note: Exclude documentation and comment-only changes from review routing
-
-Status: implemented
-
-English | [中文](2026-09-08-comment-only-review-routing.zh.md)
-
-## Problem
-
-Directory ownership alone treats documentation and comment edits like executable changes. These edits do not require the automatic code-owner request that protects behavior changes.
-
-GitHub may omit or truncate a file patch. A scanner that assumes every patch is complete can miss executable changes that occur outside the supplied hunks.
-
-## Decision
-
-Review routing classifies every old and new path in this order: test, documentation, comment-only, then reviewable code. Test classification wins when a test path also has a documentation extension. Every filename ending in `.md` or `.yaml`, matched without case sensitivity, is documentation. A `.yml` file is not documentation under this rule.
-
-Comment-only classification applies only to files with `status: modified` and a declared source-comment syntax. The scanner reconstructs the before and after text for each patch hunk, removes comments outside quoted strings, removes empty lines left by comments, and requires the remaining text to be identical.
-
-The scanner counts added and deleted patch lines and compares them with GitHub's file record before accepting a comment-only result. A missing patch, a count mismatch, a rename, an unsupported extension, or a comment form that remains visible to the lexer keeps the file reviewable. This fail-safe result can request an unnecessary review but cannot suppress a known code change.
-
-The supported lexical rules cover C-style line and block comments, hash comments, SQL comments, CSS block comments, and HTML comments for an explicit extension set in the scanner. Comment directives such as JSDoc tags, lint controls, compiler controls, and coverage controls are comments for routing purposes.
-
-## Verification
-
-[Scanner tests](../../../../.github/review-ownership/request-review.test.mjs) cover documentation extensions, supported comment forms, quoted comment markers, executable token changes, incomplete patches, renames, unsupported extensions, exclusion precedence, and the no-request result when every file is excluded.
-
-## Alternatives considered
-
-**Keep every non-test file reviewable.** This requests code owners for documentation and comment maintenance even though the routing policy is intended to identify executable changes.
-
-**Infer arbitrary semantic equivalence.** Proving behavior equivalence across the repository's languages requires language toolchains and still cannot assign one stable meaning to generated files, configuration, or build directives. The scanner performs only lexical comment removal.
-
-**Trust every patch returned by GitHub.** GitHub can omit or truncate patches. Matching the patch's added and deleted line counts to the file record prevents a partial patch from producing a comment-only verdict.
-
-**Fetch and parse every complete file revision.** Per-file content requests multiply API traffic for large pull requests and still require the same language-specific parsing. The changed-file response already carries enough evidence for complete ordinary patches.
-
-## Consequences
-
-Documentation and proven comment-only changes request nobody. The workflow logs them separately from tests so maintainers can audit why owner matching ignored a file.
-
-Unsupported or incomplete inputs remain reviewable. Comment directives do not request owners even when another tool interprets them, because this policy classifies their lexical form rather than downstream tool behavior.

-# Agent Note: 从评审路由中排除文档和纯注释变更
-
-Status: implemented
-
-[English](2026-09-08-comment-only-review-routing.md) | 中文
-
-## 问题
-
-只按目录分配 owner 会把文档和注释编辑视为可执行变更。这些编辑不需要用于保护行为变更的自动代码 owner 请求。
-
-GitHub 可能省略或截断文件 patch。如果扫描器假定每个 patch 都完整，就可能漏掉位于已提供 hunk 之外的可执行变更。
-
-## 决策
-
-评审路由按测试、文档、纯注释、可评审代码的顺序对每个新旧路径分类。当测试路径同时具有文档扩展名时，测试分类优先。所有以 `.md` 或 `.yaml` 结尾的文件均视为文档，扩展名匹配不区分大小写；此规则不把 `.yml` 文件视为文档。
-
-纯注释分类只适用于 `status: modified` 且已声明源码注释语法的文件。扫描器重建每个 patch hunk 的变更前后文本，移除引号字符串外的注释和注释留下的空行，并要求其余文本完全相同。
-
-扫描器会统计 patch 的新增行和删除行，并在接受纯注释结果前与 GitHub 文件记录比较。缺失 patch、计数不符、重命名、不受支持的扩展名，或词法分析器仍能看到的注释形式都会使文件保持可评审状态。该保守结果可能产生不必要的评审请求，但不会隐藏已知代码变更。
-
-受支持的词法规则按扫描器中显式的扩展名集合覆盖 C 风格行注释和块注释、井号注释、SQL 注释、CSS 块注释及 HTML 注释。JSDoc 标签、lint 控制、编译器控制和覆盖率控制等注释指令在评审路由中仍属于注释。
-
-## 验证
-
-[扫描器测试](../../../../.github/review-ownership/request-review.test.mjs)覆盖文档扩展名、受支持的注释形式、引号内的注释标记、可执行 token 变更、不完整 patch、重命名、不受支持的扩展名、排除优先级，以及所有文件均被排除时不发出请求的结果。
-
-## 考虑过的替代方案
-
-**让每个非测试文件都保持可评审。** 这会为文档和注释维护请求代码 owner，但该路由策略的目标是识别可执行变更。
-
-**推断任意语义等价。** 证明仓库中多种语言的行为等价需要各语言工具链，而且仍然无法为生成文件、配置或构建指令提供一种稳定含义。扫描器只执行词法注释移除。
-
-**信任 GitHub 返回的每个 patch。** GitHub 可能省略或截断 patch。将 patch 的新增和删除行数与文件记录匹配，可以防止不完整 patch 产生纯注释结论。
-
-**获取并解析每个文件的完整修订版本。** 对于大型 PR，逐文件内容请求会增加多倍 API 流量，而且仍需相同的语言专用解析。普通完整 patch 所需的证据已包含在变更文件响应中。
-
-## 后果
-
-文档和确认的纯注释变更不会请求任何人。Workflow 会将它们与测试分开记录，以便维护者检查 owner 匹配忽略文件的原因。
-
-不受支持或不完整的输入仍需评审。即使其他工具会解释注释指令，这些指令也不会请求 owner，因为该策略按词法形式分类，而不是按下游工具行为分类。

-# Agent Note: Route reviews from trusted changed-file policy
-
-Status: implemented
-
-## Problem
-
-GitHub's native CODEOWNERS behavior requests reviewers whenever a matching path changes. It cannot apply this repository's distinction between reviewable implementation or documentation files and test-only evidence. A native CODEOWNERS file also makes GitHub, rather than an inspected repository program, responsible for the request decision.
-
-Review routing needs an observable changed-file input, explicit owner rules, complete test exclusions, and a write-capable workflow that remains safe for pull requests from forks.
-
-## Decision
-
-The repository keeps a CODEOWNERS-compatible map at [`.github/review-ownership/CODEOWNERS`](../../../../.github/review-ownership/CODEOWNERS), outside GitHub's native CODEOWNERS locations. The map accepts only explicit absolute directory patterns with one or two individual GitHub users. It rejects wildcards, hidden-directory patterns, teams, more than two owners, duplicate patterns, and duplicate owners. Later matching patterns replace earlier matches.
-
-The policy test counts non-test tracked lines in directories that match an ownership rule. It rejects a map in which `@turtle1999` owns more than one third of that eligible owned codebase.
-
-The [`request-review` workflow](../../../../.github/workflows/request-review.yml) runs on `pull_request_target` events for opened, synchronized, reopened, ready-for-review, and converted-to-draft pull requests. Its write-capable job checks out the default branch and executes only the default branch's scanner and ownership map. It does not check out pull-request code or read repository secrets.
-
-The scanner fetches every changed-file record before deciding. It fails if the pull request reports more than GitHub's 3,000-file API limit or if pagination returns an incomplete list. It normalizes repository paths, evaluates old and new paths of a rename independently, and escapes filenames before logging them.
-
-The scanner excludes test-only paths before owner matching. Excluded paths comprise directories named `test`, `tests`, `__tests__`, `__snapshots__`, `benches`, or `stress-tests`; the top-level `benchmarks` and `snapshots` trees; `packages/test-support`; `scripts/fixtures` and `scripts/snapshots`; filenames ending in `.bench.<ext>`, `.corpus.<ext>`, `.e2e.<ext>`, `.perf.<ext>`, `.snapshot.<ext>`, `.spec.<ext>`, `.stress.<ext>`, or `.test.<ext>`; and Python `test_*.py`, `*_test.py`, or `*_tests.py` files. Test infrastructure such as `vitest*.config.ts` and gate implementations remains reviewable because it changes how repository evidence is produced. The [comment-only routing decision](2026-09-08-comment-only-review-routing.md) owns the additional documentation and comment exclusions.
-
-The workflow prints the changed code paths, each exclusion class, per-file owner matches and changed LOC, aggregate owner relevance, approved owners omitted from new requests, current individual requests, the available counted slot after planned cancellations, and final reviewer actions before any review-request mutation. For a non-draft pull request, it fetches the complete chronological review list and reduces each owner's undismissed `APPROVED` and `CHANGES_REQUESTED` reviews to the latest decisive state; `COMMENTED` and `PENDING` reviews leave that state unchanged. It removes the pull-request author, owners with an active approval, and users who remain requested from the matched individual owners. An active approval remains sufficient after later synchronize events, while a later changes-requested review makes the owner eligible again. The review-list operation fails before mutation at 3,000 entries or on an invalid record.
-
-The workflow keeps at most one current individual review request other than `@turtle1999`. An existing request for `@turtle1999` does not consume that slot, but each workflow run adds at most one reviewer. An existing non-turtle request leaves no slot, so the workflow does not add anyone, including `@turtle1999`. Existing individual requests consume the slot even when they do not match the ownership map. An owner's relevance is the sum of GitHub-reported additions and deletions for each reviewable changed-file record whose current or previous path matches that owner. Each record contributes once per owner, including when both paths of a rename match the same owner. Higher changed LOC selects candidates first when the available slot cannot cover the remaining owners; login order resolves equal scores.
-
-When current review requests exist, the workflow reads the complete review-request timeline before mutation. A current reviewer is workflow-authored only when its latest matching `review_requested` event identifies `github-actions[bot]` as `review_requester`; a request without an attributable event is preserved. A non-draft run cancels workflow-authored reviewers that no longer match the current candidates and excess workflow-authored non-turtle reviewers above the counted limit; current relevance order selects which matching workflow reviewer remains. Planned cancellations release capacity before the workflow selects a new reviewer. A draft run cancels every current workflow-authored request. Requests made by people remain unchanged. An attributable event with invalid provenance and timelines above 3,000 events fail before mutation.
-
-## Verification
-
-[Scanner tests](../../../../.github/review-ownership/request-review.test.mjs) cover admitted ownership syntax, rejected syntax, each exclusion class, production-name negative controls, renames, last-match behavior, unmatched files, changed-LOC aggregation and ranking, complete pagination, file and review limits, approval-state reduction, approved-owner suppression and next-owner selection, log-before-mutation ordering, author and existing-reviewer filtering, non-draft reconciliation, draft cancellation provenance, and API failures. [Workflow tests](../../../../scripts/ci-workflow.spec.ts) pin the event set, least permissions, trusted default-branch checkout, absence of pull-request-head references and secrets, and executed command. The gate graph includes both suites in static CI and `check-all`.
-
-## Alternatives considered
-
-**Use native CODEOWNERS.** Native routing cannot ignore test-only changes and offers no repository-owned decision log before requesting reviewers.
-
-**Run under `pull_request` and check out the pull-request head.** A fork workflow does not receive a write-capable token, while granting a write token to code from an untrusted head is unsafe.
-
-**Execute the pull request's scanner or owner map under `pull_request_target`.** This lets an untrusted pull request choose its own write-capable behavior or owners.
-
-**Select capped candidates by login order.** Login order is stable but ignores how much reviewable code changed under each owner's directories. Changed LOC makes the limited requests follow the pull request's strongest ownership relevance while retaining login order for ties.
-
-**Cancel every reviewer that no longer matches.** A person may request a reviewer for reasons outside the ownership map. Only requests attributed to the workflow identity are safe for automated reconciliation.
-
-**Treat an empty current request as an owner who still needs review.** GitHub removes the pending request when the reviewer submits a review. Requesting an owner with an active approval again adds no ownership coverage and creates repeated notifications after later synchronize events.
-
-**Infer arbitrary semantic source changes from patches or language parsers.** GitHub can omit or truncate patches, and the repository spans many languages. The scanner does not try to prove that two programs behave identically. The later [comment-only routing decision](2026-09-08-comment-only-review-routing.md) adds a narrow lexical comparison only when changed-line counts prove that GitHub supplied the complete patch.
-
-## Consequences
-
-Reviewer mutations are reproducible from a trusted policy, the file classifications printed in the workflow log, and review-request provenance in the pull-request timeline. Excluded changes do not request owners, rule and changed-file updates remove obsolete workflow-authored requests on the next run, and draft pull requests do not retain workflow-authored requests. Ownership changes become effective only after merge, so the pull request that changes policy cannot apply its untrusted policy to itself.
-
-The workflow requests at most one reviewer per run, does not repeat a request while that owner has an active approval, keeps no more than one current individual reviewer other than `@turtle1999`, and prefers owners whose matched reviewable files carry more changed LOC. An existing `@turtle1999` request leaves the counted slot available; an existing non-turtle request prevents every additional request. Shared ownership gives each owner the same file-level relevance without counting one renamed file twice for the same owner. GitHub-generated review-request events may not start other workflows that depend on recursively triggered events from `GITHUB_TOKEN`; those workflows must not rely on this request as their only trigger.
-
-Any change that does not match an explicit exclusion remains eligible under an owned directory. Unmatched paths are logged and request nobody. Pull requests above the file, review, or timeline API limit fail without applying a partial reviewer mutation.

-## Routing
-
-Pull requests run the workflow when opened, synchronized, reopened, marked ready for review, or converted to a draft. The scanner fetches the complete pull-request file list, evaluates both paths of a rename, and fails instead of routing from a partial list. GitHub exposes at most 3,000 files for this API.
-
-For a non-draft pull request, the workflow keeps at most one current individual review request other than `@turtle1999`; an existing request for `@turtle1999` does not consume that slot. Each run adds at most one reviewer. An existing non-turtle request leaves no slot, so the workflow does not add anyone, including `@turtle1999`. Existing individual requests consume the slot even when made by people outside the ownership map. When more candidates remain than the available counted slot can cover, the workflow ranks them by the total GitHub-reported additions plus deletions in reviewable changed-file records that match each owner. A rename contributes its changed LOC once to an owner even when both paths match that owner. Higher changed LOC ranks first, and login order resolves ties.
-
-Before selecting a new reviewer, a non-draft run fetches the pull request's complete chronological review list. An owner's latest undismissed decisive review is `APPROVED` or `CHANGES_REQUESTED`; comments and pending reviews do not replace that decision. An approved owner remains omitted after later synchronize events, while a later changes-requested review makes the owner eligible again. The workflow fails before mutation when the list reaches the supported 3,000-review limit or contains an invalid record.
-
-On every run with current review requests, the workflow reads the pull-request timeline. A current reviewer is workflow-authored only when the latest matching `review_requested` event names `github-actions[bot]` as `review_requester`; a request without an attributable event is preserved. On a non-draft pull request, the workflow cancels workflow-authored reviewers that no longer match the current candidates and excess workflow-authored non-turtle reviewers above the counted limit. Current relevance order decides which matching workflow reviewer remains when the limit shrinks. It then fills any slot left by the planned cancellations. On a draft, it cancels every current workflow-authored request. Requests made by people remain unchanged in both states. An attributable event with invalid provenance fails before mutation, and the workflow also fails without cancellation when the timeline exceeds 3,000 events.
-
-The ownership map accepts explicit absolute directory patterns and one or two individual GitHub users per pattern. It rejects wildcards, hidden-directory patterns, teams, more than two owners, and duplicate patterns or owners. Matching follows CODEOWNERS last-match semantics. The scanner prints the changed code, excluded test, documentation, and comment-only files; per-file owner matches and LOC; the aggregate owner relevance ranking; approved owners omitted from new requests; current individual requests and the available counted slot after planned cancellations; and the reviewers it will request or cancel before it mutates review requests. Unmatched files remain visible in the log. The pull-request author, approved owners, and users who remain requested are omitted from new requests.
-
-The policy test measures non-test tracked lines under matched directories and requires `@turtle1999` to own no more than one third of that eligible owned codebase.

 ## Approval scoring

 The publisher runs when a pull request opens, synchronizes, reopens, becomes ready, or becomes a draft. Review submissions, edits, and dismissals run the no-permission [`weighted-approval-review-event` workflow](../workflows/weighted-approval-review-event.yml); its validated run title supplies the pull-request number to the default-branch publisher. The publisher validates the current head, fetches every review, and resolves current repository permission before publishing the status. Permission changes take effect on the next subscribed pull-request or review event.
 
-<a id="review-exclusions"></a>

-## Review exclusions
-
-Review routing excludes the repository's unit, end-to-end, expected-output, snapshot, benchmark, performance, stress, corpus, native, and Python test conventions. This includes `test`, `tests`, `__tests__`, `__snapshots__`, `benches`, and `stress-tests` directories; the top-level `benchmarks` and `snapshots` trees; `packages/test-support`; `scripts/fixtures` and `scripts/snapshots`; recognized test filename suffixes; and Python `test_*.py` or `*_test.py` files.
-
-Test infrastructure that can alter how evidence is produced remains reviewable, including `vitest*.config.ts` and gate implementations under `scripts`. A production file named `test.ts`, `spec.ts`, or `snapshot.ts` is not excluded solely by that name.
-
-Files ending in `.md` or `.yaml`, with case-insensitive extension matching, are documentation and never contribute owners. A `.yml` file remains reviewable unless another exclusion applies.
-
-For a modified file with a supported source extension, the scanner compares the pre-change and post-change text after removing parsed comments. It excludes the file only when GitHub supplies a patch whose counted additions and deletions prove that the patch is complete and the remaining code is identical. The parser recognizes C-style line and block comments, hash comments, SQL comments, CSS block comments, and HTML comments for their declared extensions. Renames, unsupported languages, missing or partial patches, and uncertain comment forms remain reviewable.
-
 <a id="security"></a>
 
 ## Security
 
-The write-capable jobs check out only the repository default branch. They do not check out or execute pull-request code and do not use repository secrets. The review-event workflow has no `GITHUB_TOKEN` permissions and passes only a decimal pull-request number in its run title. The publisher rejects an invalid run title and a number that does not resolve to the workflow run's current pull-request head. Pull-request filenames and reviews are treated as API data and escaped in logs.

+# Agent Note: CI tests observe completion instead of host speed
+
+Status: implemented
+

+
+## Problem
+
+The [reference CI run](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34206953049) rejects two asynchronous operations before their enclosing test budgets expire: a webhook-created Session is absent after the test’s one-second poll, and a background PowerShell command has emitted no output before its five-second read deadline. Neither API promises those latency bounds. A successful HTTP 202 response acknowledges webhook dispatch, not Session creation or model admission.
+
+## Decision
+
+The [GitHub review browser test](../../../../apps/web/tests/github-ready-review.e2e.ts) awaits the deterministic adapter’s first request before asserting exact Agent and request counts. A deferred Workspace-creation barrier proves that HTTP acceptance can precede both observations; the barrier delegates to the real method and is released and restored in `finally`. The original Workspace membership, prompt content, reply, and collapsed/expanded browser expectations remain authoritative.
+
+The [PowerShell executor tests](../../../../packages/shell/pwsh-local/tests/executor.spec.ts) await `done` before reading complete stdin/environment output. Startup and consuming-read checks hold the command at a private file barrier, so the running state and unread later output do not depend on a sleep or elapsed-time threshold. Partial-output polling inherits the lane budget. Every created Context is registered for teardown before use; subprocess disposal precedes private-directory removal. A six-second delayed command reproduces the five-second failure and passes after the completion wait on native Windows.
+
+The enclosing test timeout remains the watchdog. Completion assertions do not acquire a second, shorter performance requirement merely because an operation crosses a process, filesystem, or event-loop boundary. This extends the [subagent teardown budget decision](2026-09-07-subagent-teardown-test-budgets.md) without replacing its disposal ownership or native-platform verification requirements. The [browser e2e decision](2026-07-24-web-gui-browser-e2e-lane.md) continues to own the assembled browser lane and recorded expectations.
+
+The [Queue browser test](../../../../apps/web/tests/queue-actions.e2e.ts) observes the collapsed sidebar and completed frame animations after a narrow resize, then reads both card rectangles and the declared inset in one browser evaluation. Separate round trips can mix a pre-resize Queue coordinate with a post-resize composer coordinate even when their inset is correct in both frames. A controlled resize barrier reproduces that mismatch; the same control passes with the atomic observation.
+
+The [publint runner tests](../../../../scripts/publint-all.spec.ts) await asynchronous child closure under the lane budget instead of imposing a five-second synchronous spawn deadline. They check spawn errors and termination signals independently of exit status. Teardown captures children and fixture roots before awaiting, terminates unfinished children, and joins closure before deleting roots. A delayed startup reproduces the former null-status failure; a forced outer timeout verifies that the child is gone while its root still exists.
+
+### Built-client import classification
+
+The [master Windows run](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34204779455/job/101996934534) also rejects the intentional CSS import exposed by `ui-dockkit`. The [Node import sweep](../../../../packages/experimental/webworker-runtime/tests/compile/transform-corpus-check.ts) admits that exact bundle only when Node reports `ERR_UNKNOWN_FILE_EXTENSION` for its `dockkit.module.css`. Other errors at the same entry still fail, and an entry that imports successfully reports a stale exemption. This preserves the import sweep without requiring a browser-only component library to load its stylesheet under bare Node.
+
+## Alternatives considered
+
+- Increase production timeouts or add test retries: neither establishes which operation completed, and both change behavior unrelated to the failing assertion.
+- Replace the local deadline with a larger constant: this still overrides future lane budgets and leaves correctness dependent on host speed.
+- Accept HTTP 202 or process startup as success: neither proves the expected model request or command output.
+- Serialize the coverage or browser suite: the failures do not establish a shared-resource collision requiring suite-wide exclusion.
+
+## Consequences
+
+A controlled pause before Workspace creation reproduces the reference assertion with the original polling wait. Releasing the barrier and awaiting the request passes the same browser expectations without rewriting goldens. These controls prove the synchronization defect; they do not measure historical runner contention. Product behavior, production timing, and CI scheduling remain unchanged.

+# Agent Note: CI 测试观察完成状态而非主机速度
+
+Status: implemented
+
+[English](2026-09-08-ci-completion-observations.md) | 中文
+
+## Problem
+
+[参考 CI 运行](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34206953049)在外层测试预算耗尽前拒绝了两个异步操作：webhook 创建的 Session 在测试轮询一秒后仍不存在，后台 PowerShell 命令在五秒读取期限内尚未输出内容。两个 API 都没有承诺这些延迟上限。成功的 HTTP 202 响应只确认 webhook 已分发，不代表 Session 已创建或模型请求已接纳。
+
+## Decision
+
+[GitHub 评审浏览器测试](../../../../apps/web/tests/github-ready-review.e2e.ts)先等待确定性适配器收到首个请求，再断言 Agent（智能体）和请求的精确数量。Workspace 创建的延迟屏障证明 HTTP 接纳可以早于这两项观察；屏障委托真实方法，并在 `finally` 中释放和恢复。原有的 Workspace 成员关系、提示词内容、回复以及折叠和展开浏览器预期仍然是判定依据。
+
+[PowerShell 执行器测试](../../../../packages/shell/pwsh-local/tests/executor.spec.ts)先等待 `done`，再读取完整的 stdin 和环境变量输出。启动及消费式读取检查用私有文件屏障阻止命令结束，因此运行状态和未读的后续输出不依赖 sleep 或耗时阈值。部分输出轮询继承 lane 预算。每个创建的 Context 都在使用前登记清理；子进程释放先于私有目录删除。在原生 Windows 上，延迟六秒的命令复现五秒期限失败，而改用完成等待后通过。
+
+外层测试超时仍负责防止挂起。完成状态断言不会仅因操作跨越进程、文件系统或事件循环边界，就额外附带一个更短的性能要求。这扩展了 [subagent 清理预算决策](2026-09-07-subagent-teardown-test-budgets.zh.md)，但不替代其 dispose（资源释放）所有权和原生平台验证要求。[浏览器 e2e 决策](2026-07-24-web-gui-browser-e2e-lane.zh.md)继续负责完整组合浏览器 lane 和录制预期。
+
+[Queue 浏览器测试](../../../../apps/web/tests/queue-actions.e2e.ts)在缩窄视口后观察侧栏已折叠且框架动画已完成，再在一次浏览器执行中读取两张卡片的矩形和声明的内边距。分开的往返可能混合调整前的 Queue 坐标和调整后的输入框坐标，即使两个时刻的内边距都正确。受控的尺寸调整屏障复现了这种不匹配；改用原子观察后，相同对照通过。
+
+[publint 运行器测试](../../../../scripts/publint-all.spec.ts)在 lane 预算内等待异步子进程关闭，而不施加五秒同步 spawn 期限。测试独立检查 spawn 错误、终止信号和退出码。清理在等待前取得子进程和 fixture 根目录，终止尚未完成的子进程，并在删除根目录前等待关闭。延迟启动复现了原来的空退出码失败；强制触发外层超时则验证子进程已经结束，而其根目录仍然存在。
+
+### 已构建客户端的导入分类
+
+[master Windows 运行](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34204779455/job/101996934534)还拒绝了 `ui-dockkit` 有意暴露的 CSS 导入。[Node 导入检查](../../../../packages/experimental/webworker-runtime/tests/compile/transform-corpus-check.ts)仅在 Node 针对其 `dockkit.module.css` 报告 `ERR_UNKNOWN_FILE_EXTENSION` 时，才允许这个精确的 bundle。相同入口的其他错误仍然失败，成功导入则报告豁免已过期。这保留了导入检查，同时不要求仅面向浏览器的组件库在裸 Node 中加载样式表。
+
+## Alternatives considered
+
+- 增大生产超时或添加测试重试：两者都无法确定哪个操作已经完成，而且会改变与失败断言无关的行为。
+- 用更大的常量替换局部期限：这仍然覆盖未来的 lane 预算，并使正确性依赖主机速度。
+- 将 HTTP 202 或进程启动视为成功：两者都不能证明预期模型请求或命令输出已经发生。
+- 串行化覆盖率或浏览器套件：这些失败没有证明存在必须对整个套件互斥的共享资源冲突。
+
+## Consequences
+
+在 Workspace 创建前受控暂停，可以用原来的轮询等待复现参考断言。释放屏障并等待请求后，相同浏览器预期通过，无需改写 golden。这些对照证明了同步缺陷，但没有测量历史 runner 的资源争抢。产品行为、生产时序和 CI 调度保持不变。

+The GitHub webhook scenario awaits the deterministic model adapter’s first request before inspecting its created Session; HTTP 202 only acknowledges dispatch. Its controlled Workspace-creation barrier verifies that distinction without a short polling deadline.

 Acceptance lives in `apps/web/tests/preview-boot.e2e.ts`, which serves the real built pages and drives the pre-boot chooser plus Worker activation in headless Chromium. The empty selection exercises first-run startup. The `vfs-example` overlay supplies ordinary workspace files and plaintext persistence artifacts for cold Workspace/Session discovery, tool presentation, subagent navigation, and history paging without a model request. The fixture generator owns current-generation logs and the projection cache; committed predecessor logs remain byte-identical alongside them. The chooser reserves WebFS as a separate user-authorized source; that provider does not read the built-in fixture.

Its Dockkit exception accepts only Node’s unknown-extension error for the expected stylesheet; other failures and unexpectedly successful exempt imports remain errors.

 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-range exit. Cleanup failures remain observable as ordered safe facts and never claim quiescence.
 
+The [disposal tests](tests/subagent-acp.spec.ts) observe real child exit under the lane budget and distinguish POSIX signal escalation from Windows force termination; cleanup joins child exit before deleting marker directories. See the [teardown-test decision](../../../.agents/notes/implemented/testing/2026-09-07-subagent-teardown-test-budgets.md).

 ### 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).

 The parent bounds every child to 60 seconds, checks timeout, signal, exit, and report independently, awaits process close, and removes private roots after failures. Context and Agent teardown run in finally blocks. Seed processes cannot warm the measured process's caches.

 The [publint runner tests](../../../../scripts/publint-all.spec.ts) await asynchronous child closure under the lane budget instead of imposing a five-second synchronous spawn deadline. They check spawn errors and termination signals independently of exit status. Teardown captures children and fixture roots before awaiting, terminates unfinished children, and joins closure before deleting roots. A delayed startup reproduces the former null-status failure; a forced outer timeout verifies that the child is gone while its root still exists.
 
+The [Details Session-lifecycle test](../../../../apps/web/tests/details-session-lifecycle.e2e.ts) awaits the frame’s captured animation promises after closed state appears, then retains the zero-width assertion. Completed and cancelled transitions both reach that assertion; cancellation cannot make a persistent nonzero track pass. A paused real grid transition reproduces the close assertion failure and completes successfully only after release, while a persistent one-pixel track remains rejected.

 ### Built-client import classification
 
 The [master Windows run](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34204779455/job/101996934534) also rejects the intentional CSS import exposed by `ui-dockkit`. The [Node import sweep](../../../../packages/experimental/webworker-runtime/tests/compile/transform-corpus-check.ts) admits that exact bundle only when Node reports `ERR_UNKNOWN_FILE_EXTENSION` for its `dockkit.module.css`. Other errors at the same entry still fail, and an entry that imports successfully reports a stale exemption. This preserves the import sweep without requiring a browser-only component library to load its stylesheet under bare Node.

+The [GitHub review browser test](../../../../apps/web/tests/github-ready-review.e2e.ts) awaits the deterministic adapter’s first request before asserting exact Agent and request counts. A deferred Workspace-creation barrier proves that HTTP acceptance can precede both observations; the barrier delegates to the real method and is released and restored in `finally`, with independent `onTestFinished` cleanup if the request itself stalls beyond the test timeout. The original Workspace membership, prompt content, reply, and collapsed/expanded browser expectations remain authoritative.
 
 The [PowerShell executor tests](../../../../packages/shell/pwsh-local/tests/executor.spec.ts) await `done` before reading complete stdin/environment output. Startup and consuming-read checks hold the command at a private file barrier, so the running state and unread later output do not depend on a sleep or elapsed-time threshold. Partial-output polling inherits the lane budget. Every created Context is registered for teardown before use; subprocess disposal precedes private-directory removal. A six-second delayed command reproduces the five-second failure and passes after the completion wait on native Windows.

 The [Details Session-lifecycle test](../../../../apps/web/tests/details-session-lifecycle.e2e.ts) awaits the frame’s captured animation promises after closed state appears, then retains the zero-width assertion. Completed and cancelled transitions both reach that assertion; cancellation cannot make a persistent nonzero track pass. A paused real grid transition reproduces the close assertion failure and completes successfully only after release, while a persistent one-pixel track remains rejected.
 
+The [feedback-release test](../../../../apps/web/tests/feedback-release.e2e.ts) waits for the model menu to close after selection: its projected label can change while the selection response remains in flight. The [queued-image test](../../../../apps/web/tests/queue-image.e2e.ts) distinguishes the optimistic preview from the durable row’s attachment; thumbnail capture follows admission and the durable attachment response. Held-response controls pin both orderings, and independent test-finished cleanup releases intercepted requests even after timeout.
+
+The [wide-table test](../../../../apps/web/tests/markdown-wide-table.e2e.ts) waits for requested and rendered frame tracks to agree and for the conversation ResizeObserver to publish the current rendered width. Two identical intermediate table widths do not prove those inputs settled. Paused native transitions and delayed observer callbacks reproduce the stale breakout reading; an intentionally broken breakout still fails the unchanged geometry assertions.

 ### Built-client import classification
 
 The [master Windows run](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34204779455/job/101996934534) also rejects the intentional CSS import exposed by `ui-dockkit`. The [Node import sweep](../../../../packages/experimental/webworker-runtime/tests/compile/transform-corpus-check.ts) admits that exact bundle only when Node reports `ERR_UNKNOWN_FILE_EXTENSION` for its `dockkit.module.css`. Other errors at the same entry still fail, and an entry that imports successfully reports a stale exemption. This preserves the import sweep without requiring a browser-only component library to load its stylesheet under bare Node.

 The [wide-table test](../../../../apps/web/tests/markdown-wide-table.e2e.ts) waits for requested and rendered frame tracks to agree and for the conversation ResizeObserver to publish the current rendered width. Two identical intermediate table widths do not prove those inputs settled. Paused native transitions and delayed observer callbacks reproduce the stale breakout reading; an intentionally broken breakout still fails the unchanged geometry assertions.
 
+The [lifecycle command-menu snapshots](../../../../apps/web/tests/lifecycle-chrome.e2e.ts) wait for a catalog option before capturing English or Chinese output; a visible listbox can still contain a stable loading placeholder. The [detached-launch tests](../../../../packages/host/open-in-app/tests/launch-detached.spec.ts) drive watch time and late process events directly through the real launcher, checking that late success, failure, and error events neither unref twice nor kill the child. Real-process environment and early-exit cases remain separate. Sleeping after spawn cannot prove that a late callback ran before coverage collection.
+
+The [LSP backpressure test](../../../../packages/lsp/lsp-stdio/tests/instance.spec.ts) corks the real stdin stream at `didOpen`, writes the full document, and observes the pending write before aborting. The test observes query rejection immediately and joins disposal instead of relying on a short startup marker deadline or a sleep to infer backpressure.

 ### Built-client import classification
 
 The [master Windows run](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34204779455/job/101996934534) also rejects the intentional CSS import exposed by `ui-dockkit`. The [Node import sweep](../../../../packages/experimental/webworker-runtime/tests/compile/transform-corpus-check.ts) admits that exact bundle only when Node reports `ERR_UNKNOWN_FILE_EXTENSION` for its `dockkit.module.css`. Other errors at the same entry still fail, and an entry that imports successfully reports a stale exemption. This preserves the import sweep without requiring a browser-only component library to load its stylesheet under bare Node.

Every route asks the composition's `connection` service for a rejection first; the complete trust story — the Host/Origin fence and browser authentication — has one home in the [`src/index.ts`](src/index.ts) module comment. On top of that fence the open route validates its body at the wire: an `application/json` media type, a 64 KiB ceiling, a resolved-available catalog id, and an absolute path naming an existing directory. Resolution and icon commands run through [`@deepseek-ai/dsh-native-command`](../../util/native-command/README.md) (argv, never a shell) under their respective deadlines; PATH names go through `ctx.subprocess.resolveExecutable()` in-process.

 The [master Windows run](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34204779455/job/101996934534) also rejects the intentional CSS import exposed by `ui-dockkit`. The [Node import sweep](../../../../packages/experimental/webworker-runtime/tests/compile/transform-corpus-check.ts) admits that exact bundle only when Node reports `ERR_UNKNOWN_FILE_EXTENSION` for its `dockkit.module.css`. Other errors at the same entry still fail, and an entry that imports successfully reports a stale exemption. This preserves the import sweep without requiring a browser-only component library to load its stylesheet under bare Node.

 The [workspace-management test](../../../../apps/web/tests/workspace-management.e2e.ts) waits for restored composer focus before the next directory-dialog gesture, because workspace listing can render before Session restoration changes focus. Archive actions stay scoped to the seeded row rather than a captured fallback title that cold loading can replace; durable archive assertions retain the exact seed id.
 
+The [worker budget tests](../../../../packages/code-runtime/code-runtime-worker-thread/tests/budget.spec.ts) retain real worker execution and binding transport while controlling only host timers and event-loop-utilization samples. They prove that idle binding time can exceed the compute allowance, active time still expires with a binding pending, and the independent wall ceiling still expires. Real measured hot-loop tests remain; a small total active-time allowance cannot isolate idle accounting from worker bootstrap and host scheduling.

 ### Built-client import classification
 
 The [master Windows run](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34204779455/job/101996934534) also rejects the intentional CSS import exposed by `ui-dockkit`. The [Node import sweep](../../../../packages/experimental/webworker-runtime/tests/compile/transform-corpus-check.ts) admits that exact bundle only when Node reports `ERR_UNKNOWN_FILE_EXTENSION` for its `dockkit.module.css`. Other errors at the same entry still fail, and an entry that imports successfully reports a stale exemption. This preserves the import sweep without requiring a browser-only component library to load its stylesheet under bare Node.

 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.

 ## Problem
 
-The [reference CI run](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34206953049) rejects two asynchronous operations before their enclosing test budgets expire: a webhook-created Session is absent after the test’s one-second poll, and a background PowerShell command has emitted no output before its five-second read deadline. Neither API promises those latency bounds. A successful HTTP 202 response acknowledges webhook dispatch, not Session creation or model admission.
+The [reference CI run](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34206953049) reports a webhook-created Session absent after a one-second poll and empty PowerShell output before a five-second read deadline. HTTP acceptance, projected UI state, process startup, and durable completion are separate observations. Tests need an explicit completion condition and controls that prevent an intermediate state from satisfying it.
 
 ## Decision
 
-The [GitHub review browser test](../../../../apps/web/tests/github-ready-review.e2e.ts) awaits the deterministic adapter’s first request before asserting exact Agent and request counts. A deferred Workspace-creation barrier proves that HTTP acceptance can precede both observations; the barrier delegates to the real method and is released and restored in `finally`, with independent `onTestFinished` cleanup if the request itself stalls beyond the test timeout. The original Workspace membership, prompt content, reply, and collapsed/expanded browser expectations remain authoritative.
+The [GitHub review browser test](../../../../apps/web/tests/github-ready-review.e2e.ts) holds real Workspace creation after HTTP 202, verifies that neither the Agent nor the model request exists, then releases creation and awaits the matching Session's `turn/end`. Cleanup releases the barrier, restores the method, and removes the event listener even when the test times out. Workspace membership, request counts, prompt content, and browser expectations retain their original assertions.
 
-The [PowerShell executor tests](../../../../packages/shell/pwsh-local/tests/executor.spec.ts) await `done` before reading complete stdin/environment output. Startup and consuming-read checks hold the command at a private file barrier, so the running state and unread later output do not depend on a sleep or elapsed-time threshold. Partial-output polling inherits the lane budget. Every created Context is registered for teardown before use; subprocess disposal precedes private-directory removal. A six-second delayed command reproduces the five-second failure and passes after the completion wait on native Windows.
+The [PowerShell executor tests](../../../../packages/shell/pwsh-local/tests/executor.spec.ts) hold startup and consuming reads at private file barriers. The test controls when later output becomes available; final stdin/environment output is read after `done`. Polling uses the active test budget, and every constructed Context is registered before plugin initialization. Teardown captures Contexts and directories before awaiting disposal and removes directories only after that disposal completes.
 
-The enclosing test timeout remains the watchdog. Completion assertions do not acquire a second, shorter performance requirement merely because an operation crosses a process, filesystem, or event-loop boundary. This extends the [subagent teardown budget decision](2026-09-07-subagent-teardown-test-budgets.md) without replacing its disposal ownership or native-platform verification requirements. The [browser e2e decision](2026-07-24-web-gui-browser-e2e-lane.md) continues to own the assembled browser lane and recorded expectations.
+The [queued-image test](../../../../apps/web/tests/queue-image.e2e.ts) separately holds admission and attachment retrieval, then captures the admitted row's loaded thumbnail. Cleanup shares one promise, releases held requests, and drains their handlers before closing the browser.
 
-The [Queue browser test](../../../../apps/web/tests/queue-actions.e2e.ts) observes the collapsed sidebar and completed frame animations after a narrow resize, then reads both card rectangles and the declared inset in one browser evaluation. Separate round trips can mix a pre-resize Queue coordinate with a post-resize composer coordinate even when their inset is correct in both frames. A controlled resize barrier reproduces that mismatch; the same control passes with the atomic observation.
+The [Details Session-lifecycle test](../../../../apps/web/tests/details-session-lifecycle.e2e.ts) awaits the frame's captured animation promises after closed state appears, then checks the zero-width track. Cancelled transitions also reach that assertion; animation settlement cannot make a persistent nonzero track pass.
 
-The [publint runner tests](../../../../scripts/publint-all.spec.ts) await asynchronous child closure under the lane budget instead of imposing a five-second synchronous spawn deadline. They check spawn errors and termination signals independently of exit status. Teardown captures children and fixture roots before awaiting, terminates unfinished children, and joins closure before deleting roots. A delayed startup reproduces the former null-status failure; a forced outer timeout verifies that the child is gone while its root still exists.
+The [whole-queue steering test](../../../../apps/web/tests/steering.e2e.ts) waits for enabled steering actions and the composer's queue-steering hint. A model-stream barrier keeps the following question-composer takeover pending while the test observes steering. Teardown releases that barrier before browser closure.
 
-The [Details Session-lifecycle test](../../../../apps/web/tests/details-session-lifecycle.e2e.ts) awaits the frame’s captured animation promises after closed state appears, then retains the zero-width assertion. Completed and cancelled transitions both reach that assertion; cancellation cannot make a persistent nonzero track pass. A paused real grid transition reproduces the close assertion failure and completes successfully only after release, while a persistent one-pixel track remains rejected.
+The [workspace-management test](../../../../apps/web/tests/workspace-management.e2e.ts) waits for restored composer focus before the next directory-dialog gesture. Its archive case gives the known seed id an explicit user title through the Session controller, then uses that exact title to identify the row across reload. An unrelated restored row cannot satisfy that locator; the durable archive assertion still checks the seed id and retained log.
 
-The [feedback-release test](../../../../apps/web/tests/feedback-release.e2e.ts) waits for the model menu to close after selection: its projected label can change while the selection response remains in flight. The [queued-image test](../../../../apps/web/tests/queue-image.e2e.ts) distinguishes the optimistic preview from the durable row’s attachment; thumbnail capture follows admission and the durable attachment response. Held-response controls pin both orderings, and independent test-finished cleanup releases intercepted requests even after timeout.
+The [worker budget tests](../../../../packages/code-runtime/code-runtime-worker-thread/tests/budget.spec.ts) retain real worker execution and binding transport while controlling host timers and ELU samples. They acknowledge binding entry before exercising idle, active, and wall-clock decisions, so a bootstrap timeout cannot stand in for a budget decision during a binding. The [real-worker tests](../../../../packages/code-runtime/code-runtime-worker-thread/tests/runtime.spec.ts) independently retain actual ELU, idle-binding, and hot-loop coverage.
 
-The [wide-table test](../../../../apps/web/tests/markdown-wide-table.e2e.ts) waits for requested and rendered frame tracks to agree and for the conversation ResizeObserver to publish the current rendered width. Two identical intermediate table widths do not prove those inputs settled. Paused native transitions and delayed observer callbacks reproduce the stale breakout reading; an intentionally broken breakout still fails the unchanged geometry assertions.
+The [detached-launch tests](../../../../packages/host/open-in-app/tests/launch-detached.spec.ts) control watch time and deliver late process events through the real launcher's registered callbacks. They check one settlement, one unref, and no child kill. Real-process environment and early-exit cases remain in the [resolver tests](../../../../packages/host/open-in-app/tests/resolver.spec.ts).
 
-The [lifecycle command-menu snapshots](../../../../apps/web/tests/lifecycle-chrome.e2e.ts) wait for a catalog option before capturing English or Chinese output; a visible listbox can still contain a stable loading placeholder. The [detached-launch tests](../../../../packages/host/open-in-app/tests/launch-detached.spec.ts) drive watch time and late process events directly through the real launcher, checking that late success, failure, and error events neither unref twice nor kill the child. Real-process environment and early-exit cases remain separate. Sleeping after spawn cannot prove that a late callback ran before coverage collection.
-
-The [LSP backpressure test](../../../../packages/lsp/lsp-stdio/tests/instance.spec.ts) corks the real stdin stream at `didOpen`, writes the full document, and observes the pending write before aborting. The test observes query rejection immediately and joins disposal instead of relying on a short startup marker deadline or a sleep to infer backpressure.
-
-The [whole-queue steering test](../../../../apps/web/tests/steering.e2e.ts) waits for both enabled steering actions and the composer’s queue-steering hint before invoking the shortcut. Optimistic rows can already contain the expected text while the Host queue remains empty. A deferred model-stream barrier keeps question-composer takeover after steering; teardown releases that barrier before closing the browser.
-
-The [workspace-management test](../../../../apps/web/tests/workspace-management.e2e.ts) waits for restored composer focus before the next directory-dialog gesture, because workspace listing can render before Session restoration changes focus. Archive actions stay scoped to the seeded row rather than a captured fallback title that cold loading can replace; durable archive assertions retain the exact seed id.
-
-The [worker budget tests](../../../../packages/code-runtime/code-runtime-worker-thread/tests/budget.spec.ts) retain real worker execution and binding transport while controlling only host timers and event-loop-utilization samples. They prove that idle binding time can exceed the compute allowance, active time still expires with a binding pending, and the independent wall ceiling still expires. Real measured hot-loop tests remain; a small total active-time allowance cannot isolate idle accounting from worker bootstrap and host scheduling.
+The [LSP backpressure test](../../../../packages/lsp/lsp-stdio/tests/instance.spec.ts) preserves the real paused-reader fixture and large native pipe write. Before accepting the abort error, it verifies that the pending write callback settled and the captured subprocess completed; `instance.dead` alone can be true as soon as disposal starts.
 
 ### Built-client import classification
 
-The [master Windows run](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34204779455/job/101996934534) also rejects the intentional CSS import exposed by `ui-dockkit`. The [Node import sweep](../../../../packages/experimental/webworker-runtime/tests/compile/transform-corpus-check.ts) admits that exact bundle only when Node reports `ERR_UNKNOWN_FILE_EXTENSION` for its `dockkit.module.css`. Other errors at the same entry still fail, and an entry that imports successfully reports a stale exemption. This preserves the import sweep without requiring a browser-only component library to load its stylesheet under bare Node.
+The [Node import sweep](../../../../packages/experimental/webworker-runtime/tests/compile/transform-corpus-check.ts) admits the Dockkit bundle only when Node reports `ERR_UNKNOWN_FILE_EXTENSION` for its exact `dockkit.module.css` path. Other errors and unexpectedly successful exempt imports fail. Scoped resolve/load hooks exercise expected CSS failure, arbitrary failure, another stylesheet, another error code, and stale exemption without modifying shared build artifacts.
 
 ## Alternatives considered
 
-- Increase production timeouts or add test retries: neither establishes which operation completed, and both change behavior unrelated to the failing assertion.
-- Replace the local deadline with a larger constant: this still overrides future lane budgets and leaves correctness dependent on host speed.
-- Accept HTTP 202 or process startup as success: neither proves the expected model request or command output.
-- Serialize the coverage or browser suite: the failures do not establish a shared-resource collision requiring suite-wide exclusion.
+- Increase production timeouts, add retries, or serialize the suite: none establishes the missing completion observation.
+- Infer completion from HTTP 202, an optimistic image, or a projected label: each can precede the operation being asserted.
+- Replace real worker timing coverage with controlled samples: that would omit verification of Node's actual ELU and transport behavior.
 
 ## Consequences
 
-A controlled pause before Workspace creation reproduces the reference assertion with the original polling wait. Releasing the barrier and awaiting the request passes the same browser expectations without rewriting goldens. These controls prove the synchronization defect; they do not measure historical runner contention. Product behavior, production timing, and CI scheduling remain unchanged.
+Each fixture owns its clocks, barriers, callbacks, processes, and temporary paths. Controlled observations supplement real worker, subprocess, browser, and persistence paths. Product behavior, production timing, benchmark budgets, CI scheduling, and recorded expectations remain unchanged.

-## Problem
+## 问题
 
-[参考 CI 运行](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34206953049)在外层测试预算耗尽前拒绝了两个异步操作：webhook 创建的 Session 在测试轮询一秒后仍不存在，后台 PowerShell 命令在五秒读取期限内尚未输出内容。两个 API 都没有承诺这些延迟上限。成功的 HTTP 202 响应只确认 webhook 已分发，不代表 Session 已创建或模型请求已接纳。
+[参考 CI 运行](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34206953049)报告：轮询一秒后 webhook 创建的 Session 仍不存在，五秒读取期限内 PowerShell 输出为空。HTTP 接受、UI 投影状态、进程启动和持久化完成是不同的观察。测试需要明确的完成条件，并用对照阻止中间状态满足该条件。
 
-## Decision
+## 决策
 
-[GitHub 评审浏览器测试](../../../../apps/web/tests/github-ready-review.e2e.ts)先等待确定性适配器收到首个请求，再断言 Agent（智能体）和请求的精确数量。Workspace 创建的延迟屏障证明 HTTP 接纳可以早于这两项观察；屏障委托真实方法，并在 `finally` 中释放和恢复；如果请求本身挂起并超过测试超时，独立的 `onTestFinished` 清理仍会释放和恢复屏障。原有的 Workspace 成员关系、提示词内容、回复以及折叠和展开浏览器预期仍然是判定依据。
+[GitHub 评审浏览器测试](../../../../apps/web/tests/github-ready-review.e2e.ts)在 HTTP 202 后阻塞真实 Workspace 创建，验证 Agent 和模型请求均不存在，再释放创建并等待对应 Session 的 `turn/end`。即使测试超时，清理也会释放屏障、恢复方法并移除事件监听器。Workspace 归属、请求数量、提示词内容和浏览器预期保留原有断言。
 
-[PowerShell 执行器测试](../../../../packages/shell/pwsh-local/tests/executor.spec.ts)先等待 `done`，再读取完整的 stdin 和环境变量输出。启动及消费式读取检查用私有文件屏障阻止命令结束，因此运行状态和未读的后续输出不依赖 sleep 或耗时阈值。部分输出轮询继承 lane 预算。每个创建的 Context 都在使用前登记清理；子进程释放先于私有目录删除。在原生 Windows 上，延迟六秒的命令复现五秒期限失败，而改用完成等待后通过。
+[PowerShell 执行器测试](../../../../packages/shell/pwsh-local/tests/executor.spec.ts)用私有文件屏障控制启动与消费式读取。测试决定后续输出何时可用；最终 stdin／环境变量输出在 `done` 后读取。轮询使用当前测试预算，每个创建的 Context 都在插件初始化前登记。清理在等待释放前同时取得 Context 与目录，完成释放后才删除目录。
 
-外层测试超时仍负责防止挂起。完成状态断言不会仅因操作跨越进程、文件系统或事件循环边界，就额外附带一个更短的性能要求。这扩展了 [subagent 清理预算决策](2026-09-07-subagent-teardown-test-budgets.zh.md)，但不替代其 dispose（资源释放）所有权和原生平台验证要求。[浏览器 e2e 决策](2026-07-24-web-gui-browser-e2e-lane.zh.md)继续负责完整组合浏览器 lane 和录制预期。
+[排队图片测试](../../../../apps/web/tests/queue-image.e2e.ts)分别阻塞接纳和附件读取，再捕获已接纳行中加载完成的缩略图。清理共享一个 Promise，释放保留的请求，并在关闭浏览器前等待其 handler 完成。
 
-[Queue 浏览器测试](../../../../apps/web/tests/queue-actions.e2e.ts)在缩窄视口后观察侧栏已折叠且框架动画已完成，再在一次浏览器执行中读取两张卡片的矩形和声明的内边距。分开的往返可能混合调整前的 Queue 坐标和调整后的输入框坐标，即使两个时刻的内边距都正确。受控的尺寸调整屏障复现了这种不匹配；改用原子观察后，相同对照通过。
+[详情 Session 生命周期测试](../../../../apps/web/tests/details-session-lifecycle.e2e.ts)在关闭状态出现后等待框架已捕获的动画 Promise，再检查轨道宽度为零。取消的过渡同样进入该断言；动画结束不能让持续非零的轨道通过。
 
-[publint 运行器测试](../../../../scripts/publint-all.spec.ts)在 lane 预算内等待异步子进程关闭，而不施加五秒同步 spawn 期限。测试独立检查 spawn 错误、终止信号和退出码。清理在等待前取得子进程和 fixture 根目录，终止尚未完成的子进程，并在删除根目录前等待关闭。延迟启动复现了原来的空退出码失败；强制触发外层超时则验证子进程已经结束，而其根目录仍然存在。
+[整队列 steering 测试](../../../../apps/web/tests/steering.e2e.ts)等待 steering 操作可用以及 composer 显示队列 steering 提示。模型流屏障在测试观察 steering 时阻止后续问题 composer 接管。清理在关闭浏览器前释放该屏障。
 
-[详情 Session 生命周期测试](../../../../apps/web/tests/details-session-lifecycle.e2e.ts)在关闭状态出现后等待框架已捕获的动画 Promise，再保留宽度为零的断言。完成和取消的过渡都会进入该断言；取消不能让持续非零的轨道通过。暂停真实网格过渡可以复现关闭断言失败，只有释放后才成功完成，而持续一像素的轨道仍被拒绝。
+[Workspace 管理测试](../../../../apps/web/tests/workspace-management.e2e.ts)在下一次目录对话框操作前等待恢复后的 composer 焦点。归档用例通过 Session controller 为已知 seed id 设置显式用户标题，再用该精确标题跨重载定位行。无关的恢复行无法匹配该定位器；持久化归档断言仍检查 seed id 和保留的日志。
 
-[反馈释放测试](../../../../apps/web/tests/feedback-release.e2e.ts)在选择模型后等待菜单关闭：选择响应仍在传输时，投影标签就可能变化。[排队图片测试](../../../../apps/web/tests/queue-image.e2e.ts)区分乐观预览和持久化行的附件；缩略图捕获发生在接纳和持久化附件响应之后。受控响应屏障固定这两种顺序，独立的测试完成清理即使在超时后也会释放拦截的请求。
+[Worker 预算测试](../../../../packages/code-runtime/code-runtime-worker-thread/tests/budget.spec.ts)保留真实 worker 执行与绑定传输，只控制 Host 定时器和 ELU 样本。测试先确认绑定已进入，再检验 idle、active 和壁钟决策，使启动超时不能冒充绑定期间的预算决策。[真实 worker 测试](../../../../packages/code-runtime/code-runtime-worker-thread/tests/runtime.spec.ts)独立保留实际 ELU、空闲绑定和热循环覆盖。
 
-[宽表格测试](../../../../apps/web/tests/markdown-wide-table.e2e.ts)等待请求的框架轨道与渲染轨道一致，并等待会话 ResizeObserver 发布当前渲染宽度。两次相同的中间表格宽度不能证明这些输入已稳定。暂停原生过渡和延迟观察回调能够复现过期的溢出读数；故意破坏溢出布局时，未修改的几何断言仍然失败。
+[分离启动测试](../../../../packages/host/open-in-app/tests/launch-detached.spec.ts)控制观察时间，并通过真实 launcher 登记的回调发送迟到进程事件。测试检查仅完成一次、仅 unref 一次且不终止子进程。[Resolver 测试](../../../../packages/host/open-in-app/tests/resolver.spec.ts)保留真实进程的环境变量和提前退出用例。
 
-[生命周期命令菜单快照](../../../../apps/web/tests/lifecycle-chrome.e2e.ts)在捕获英文或中文输出前等待目录选项；可见列表框仍可能包含稳定的加载占位内容。[独立启动测试](../../../../packages/host/open-in-app/tests/launch-detached.spec.ts)通过真实启动器直接控制观察时间和延迟进程事件，检查延迟成功、失败及错误事件既不会重复 unref，也不会终止子进程。真实进程的环境和提前退出用例仍独立保留。spawn 后 sleep 无法证明延迟回调在覆盖率收集前已执行。
+[LSP 背压测试](../../../../packages/lsp/lsp-stdio/tests/instance.spec.ts)保留真实暂停读取的 fixture 与大型原生管道写入。接受 abort 错误前，测试验证待处理写入回调已完成、捕获的子进程也已结束；`instance.dead` 在释放开始时就可能为真。
 
-[LSP 背压测试](../../../../packages/lsp/lsp-stdio/tests/instance.spec.ts)在 `didOpen` 处 cork 真实 stdin 流，写入完整文档，并在中止前观察待完成写入。测试立即观察查询拒绝并等待释放，不依赖短启动标记期限，也不通过 sleep 推断背压。
+### 已构建 Client 的导入分类
 
-[整队转向测试](../../../../apps/web/tests/steering.e2e.ts)在触发快捷键前等待两个已启用的转向操作，以及输入框的队列转向提示。Host 队列仍为空时，乐观行可能已经包含预期文本。延迟模型流屏障使问题输入框在转向后才接管；清理在关闭浏览器前释放该屏障。
+[Node import sweep](../../../../packages/experimental/webworker-runtime/tests/compile/transform-corpus-check.ts)只有在 Node 针对准确的 `dockkit.module.css` 路径报告 `ERR_UNKNOWN_FILE_EXTENSION` 时才接受 Dockkit bundle。其他错误以及意外成功的豁免导入都会失败。限定范围的 resolve/load hook 覆盖预期 CSS 失败、任意失败、其他 stylesheet、其他错误码和过期豁免，不修改共享构建产物。
 
-[工作区管理测试](../../../../apps/web/tests/workspace-management.e2e.ts)在下一次目录对话框操作前等待恢复后的输入框焦点，因为工作区列表可能早于 Session 恢复引发的焦点变化完成渲染。归档操作始终限定在种子行内，不依赖冷加载可能替换的已捕获备用标题；持久化归档断言保留精确种子 id。
+## 考虑过的替代方案
 
-[worker 预算测试](../../../../packages/code-runtime/code-runtime-worker-thread/tests/budget.spec.ts)保留真实 worker 执行和绑定传输，只控制宿主定时器与事件循环利用率样本。测试证明空闲绑定时间可以超过计算额度、绑定待完成时活动时间仍会触发到期，以及独立壁钟上限仍会触发到期。真实计量的热循环测试仍保留；较小的总活动时间额度无法将空闲计费与 worker 启动及宿主调度隔离。
+- 增加生产超时、增加重试或串行化整个套件：均不能建立缺少的完成观察。
+- 从 HTTP 202、乐观图片或投影标签推断完成：它们均可能早于被断言的操作。
+- 用受控样本替换真实 worker 计时覆盖：会遗漏对 Node 实际 ELU 与传输行为的验证。
 
-### 已构建客户端的导入分类
+## 影响
 
-[master Windows 运行](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34204779455/job/101996934534)还拒绝了 `ui-dockkit` 有意暴露的 CSS 导入。[Node 导入检查](../../../../packages/experimental/webworker-runtime/tests/compile/transform-corpus-check.ts)仅在 Node 针对其 `dockkit.module.css` 报告 `ERR_UNKNOWN_FILE_EXTENSION` 时，才允许这个精确的 bundle。相同入口的其他错误仍然失败，成功导入则报告豁免已过期。这保留了导入检查，同时不要求仅面向浏览器的组件库在裸 Node 中加载样式表。
-
-## Alternatives considered
-
-- 增大生产超时或添加测试重试：两者都无法确定哪个操作已经完成，而且会改变与失败断言无关的行为。
-- 用更大的常量替换局部期限：这仍然覆盖未来的 lane 预算，并使正确性依赖主机速度。
-- 将 HTTP 202 或进程启动视为成功：两者都不能证明预期模型请求或命令输出已经发生。
-- 串行化覆盖率或浏览器套件：这些失败没有证明存在必须对整个套件互斥的共享资源冲突。
-
-## Consequences
-
-在 Workspace 创建前受控暂停，可以用原来的轮询等待复现参考断言。释放屏障并等待请求后，相同浏览器预期通过，无需改写 golden。这些对照证明了同步缺陷，但没有测量历史 runner 的资源争抢。产品行为、生产时序和 CI 调度保持不变。
+每个 fixture 拥有自己的时钟、屏障、回调、进程和临时路径。受控观察补充真实 worker、子进程、浏览器和持久化路径。产品行为、生产时序、基准预算、CI 调度和录制预期均保持不变。

 ## Completion observations
 
-The GitHub webhook scenario awaits the deterministic model adapter’s first request before inspecting its created Session; HTTP 202 only acknowledges dispatch. Its controlled Workspace-creation barrier verifies that distinction without a short polling deadline. See the [completion-observation decision](../../../.agents/notes/implemented/testing/2026-09-08-ci-completion-observations.md).
-
-Queue layout assertions wait for the responsive frame to settle and sample both related rectangles in one browser evaluation; separate round trips can observe different layout states. Details-panel close assertions await the frame’s running transitions before checking zero width; published closed state alone does not imply settled geometry.
-
-Feedback selection waits for menu closure, queued-image capture waits for the durable attachment after admission, and wide-table measurements wait for frame tracks and observer-published conversation width to agree with rendered geometry.
+State-sensitive cases use Workspace, admission, attachment, and model-stream barriers to separate visible intermediate states from completed operations. Details close waits for frame transitions; archive verification assigns an explicit title to the seeded Session and follows that identity across reload. See the [CI fixture synchronization decision](../../../.agents/notes/implemented/testing/2026-09-08-ci-completion-observations.md).

 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.

 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。

 `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。

 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()` terminates the provider-managed range; `done` settles when the direct command 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.
 
-The real-process tests await `done` before asserting complete output and use private file barriers for partial-output checks. Their polling inherits the execution lane’s budget, and Context disposal precedes temporary-directory removal; see the [completion-observation decision](../../../.agents/notes/implemented/testing/2026-09-08-ci-completion-observations.md).

 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-range exit. Cleanup failures remain observable as ordered safe facts and never claim quiescence.
 
-The [disposal tests](tests/subagent-acp.spec.ts) observe real child exit under the lane budget and distinguish POSIX signal escalation from Windows force termination; cleanup joins child exit before deleting marker directories. See the [teardown-test decision](../../../.agents/notes/implemented/testing/2026-09-07-subagent-teardown-test-budgets.md).

 ### 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).

 The [present tool](../../../../packages/fs/tool-present/README.md) declares existing regular files inside the calling Session's workspace. It records paths and optional descriptions without reading or copying contents. The [deliverables plugin](../../../../packages/client/ui-deliverables/README.md) opens current workspace sources in the Host's default application. Edits are visible on the next open; deletion or movement makes the declaration unavailable. File-content preservation and copy-on-write storage are deferred until a persistence design owns them.
 
+The tool description requires `present` after writing a file the user asked to receive and before the final response, including files created through Bash or code execution. A prose path reference does not replace the call. The recorded [SVG delivery scenario](../../../../snapshots/web/present-svg/snapshot.yml) uses a user request that does not name `present`, and checks the resulting file, delivery event, and card.
+
 The tool remains an ordinary package with shared filesystem and tool error classes. Its pure type entry owns the delivery event without importing Host code into the browser. The `standard`, `ptc`, and `cordis` presets mount it; `minimal` retains its two tools. Each plugin instance correlates its executions with successful final `tools/result` notifications before appending `deliverables/presented`. Native and nested calls share this rule. A later enclosing program failure does not revoke a completed nested declaration; blocked results publish none, and same-name scoped replacements cannot publish another instance's results.
 
-An authenticated POST selects a declaration by viewed Session, event sequence, and original file index. The event carries no owning Session ID; relative paths in inherited history resolve against the viewed Session's workspace. The Host rechecks canonical workspace containment and regular-file existence before native opening. Route disposal cancels and awaits pending commands. The existing produced-file row retains its separate text-preview behavior.

 The barrier stack for replay-mode browser assertions is, in order: (1) host-side `await agent.whenIdle()` under a timeout, keyed off the in-process `turn/end` — the idle flip follows the persistence flush, so one await covers turn completion and durability; (2) browser settled poll (streaming detached, final text visible). Record-mode log harvest runs after `whenIdle()` and before scaffold disposal while the live session remains available. An in-process `turn/end` listener alone is a wrong barrier (it fires before the SSE frame reaches the browser and before the fsync); polling persistence files as a turn-completion or durability barrier is banned (slow on NFS, superseded by `whenIdle`), while a tool-controlled temp readiness marker may be polled only as an interaction gate before that completion barrier; `networkidle` is banned outright (never resolves while an SSE stream is open). Navigation assertions arm both initial `session.list` and `workspace.list` responses before page load, then wait for the seeded DOM projection; the mounted shell alone is not readiness because late bootstrap can replace controlled state.
 
+Layout assertions wait for loaded fonts, completed frame transitions, and the Conversation width publication before measuring; a synthetic resize also waits for the scheduled React update before reading a portaled panel. Directory-tree reads use the same Remote-read budget for child and root listings. Workspace reload scenarios wait for restored Session selection and composer focus before opening another path editor, because that late focus can cancel its draft. Responsive file-chip scenarios keep their measured lane inside a container-query band with explicit margin for platform font metrics.
+
 No single-shot transient-DOM assertions: every hop from replay yield to React commit can coalesce chunks, so sampling `[data-streaming]` is a race by construction. Streaming incrementality is asserted through the ordered `agent/assistant-stream` follow path, while the final durable `assistant/message` or `assistant/attempt` embeds the exact stream used for replay. `dsh-llm-replay`'s opt-in `paceMs` (default absent = burst) is a realism knob so the browser observes genuinely incremental SSE; correctness never leans on it, and abort during a pace wait cancels promptly.
 
 Pagination drivers wait for the interactive load row to leave its pending state and record the pre-request row count before scrolling. An immediately committed resident page therefore remains observable instead of becoming the baseline for a request that the scroll gesture does not repeat.

It uses CSS container-width bands to show a responsive prefix of up to six file chips. Flexbox shrinks and ellipsizes basename text, while CSS selects the matching localized `+ N files` label for omitted paths; the full path remains available as the title, and the row performs no JavaScript layout observation or horizontal scrolling.

 The [present tool](../../../../packages/fs/tool-present/README.md) declares existing regular files inside the calling Session's workspace. It records paths and optional descriptions without reading or copying contents. The [deliverables plugin](../../../../packages/client/ui-deliverables/README.md) opens current workspace sources in the Host's default application. Edits are visible on the next open; deletion or movement makes the declaration unavailable. File-content preservation and copy-on-write storage are deferred until a persistence design owns them.
 
-The tool description requires `present` after writing a file the user asked to receive and before the final response, including files created through Bash or code execution. A prose path reference does not replace the call. The recorded [SVG delivery scenario](../../../../snapshots/web/present-svg/snapshot.yml) uses a user request that does not name `present`, and checks the resulting file, delivery event, and card.
+The tool description requires `present` after writing a file the user asked to receive and before the final response, including files created through Bash or code execution. A prose path reference does not replace the call. The recorded [SVG delivery scenario](../../../../snapshots/web/present-svg/snapshot.yml) uses a user request that does not name `present`, and checks the resulting file, delivery event, and card. Its UI snapshot covers the expanded Chat transcript; navigation and composer controls belong to their own scenarios, so unrelated chrome changes cannot invalidate file-delivery expectations.
 
 The tool remains an ordinary package with shared filesystem and tool error classes. Its pure type entry owns the delivery event without importing Host code into the browser. The `standard`, `ptc`, and `cordis` presets mount it; `minimal` retains its two tools. Each plugin instance correlates its executions with successful final `tools/result` notifications before appending `deliverables/presented`. Native and nested calls share this rule. A later enclosing program failure does not revoke a completed nested declaration; blocked results publish none, and same-name scoped replacements cannot publish another instance's results.
 
-An authenticated POST selects a declaration by viewed Session, event sequence, and original file index. The event carries no owning Session ID; relative paths in inherited history resolve against the viewed Session's workspace. The Host rechecks canonical workspace containment and regular-file existence before native opening. Route disposal cancels and awaits pending commands. The “Files changed this turn” row lists successful file-tool mutations and retains its separate text-preview behavior. Its Chinese label is “本轮文件改动”; neither label implies final delivery.

+The resident composer survives no-Session and Session transitions. Whitespace hides its placeholder; a whitespace-only draft without attachments cannot be sent.

Busy Enter behavior is stored in the Host-backed `ui-conversation` settings namespace.
 
 Default sends commit optimistically: Enter clears the draft, occurrence table, and undo history in the same transaction, keeps the composer in `plain`, and runs the send as a detached attempt, so typing and further sends continue during the flight. `sendSession` registers a Session submission echo (`session.beginSubmission`) with the delivery mode before serializing, preserving selected image and file order in `pendingSubmissions`; Session derives the placement from that mode and its current running state, so idle sends use the transcript, busy Queue sends use QueueDock, and busy Steer sends use the pending-steering surface. It then yields one paint, encodes images through the browser's native `FileReader` data-URL path, and cites staged file receipts. Command submissions use the same receipts for generic files, so sending `/goal` or `/plan` never reads those browser files again. The prompt reuses the submission `requestId`; queue and history observation by that `rpcId` retires the echo once. Concurrent failures are restored together in submission order until the user edits the restored content; command submissions keep the frozen `submitting` phase. Detached attempts retain their attachment ids through admission and Session scope disposal. An observed retirement immediately exposes each image preview through the durable cache, replaces it with the canonical URL after fetching the admitted attachment, revokes each URL after its use ends, and releases file cards. Selected generic files enter one FIFO background-upload queue; `maxConcurrentFileUploads` defaults to two active Worker transports, the Conversation service retains queued and active operations plus byte progress across Session navigation, and removing a draft skips its queued transfer or aborts its active transport. Continuable subagents disable attachment intake and skip local echoes because their transport does not preserve the browser request id.

+# Agent Note: Composer placeholder emptiness
+
+Status: implemented
+
+English | [中文](2026-09-09-composer-placeholder-whitespace.zh.md)
+
+## Problem
+
+Sharing the whitespace-trimmed submission check with placeholder rendering leaves guidance drawn over a draft containing spaces.
+
+## Decision
+
+The Composer hides its placeholder whenever the raw draft is nonempty. Submission keeps its trimmed-content check. Attachments and claimed commands retain their existing placeholder suppression.
+
+## Alternatives considered
+
+**Reuse the submission check.** Whitespace has no sendable message content, but it occupies the editor and moves its caret. A shared check conflates these two states.
+
+## Consequences
+
+All placeholder variants, including queued-message steering guidance, disappear after whitespace input and return after deletion. A whitespace-only draft without attachments remains unsendable. [Component tests](../../../../packages/client/ui-conversation/tests/input-bar.client.spec.tsx) cover visibility, composition, rerendering and submission; the [browser regression](../../../../apps/web/tests/composer-placeholder.e2e.ts) checks keyboard and clipboard gestures against built UI.

+# Agent Note: Composer 占位提示的判空规则
+
+Status: implemented
+
+[English](2026-09-09-composer-placeholder-whitespace.md) | 中文
+
+## Problem
+
+占位提示复用去除首尾空白后的提交判断，会让提示文字覆盖已经包含空格的草稿。
+
+## Decision
+
+原始草稿非空时，Composer 隐藏占位提示。提交仍检查去除首尾空白后的内容。附件和已认领指令沿用现有的占位提示隐藏规则。
+
+## Alternatives considered
+
+**复用提交判断。** 空白字符没有可发送的消息内容，但会占据编辑器并移动光标。共用判断会混淆这两种状态。
+
+## Consequences
+
+所有占位提示，包括排队消息的插话提示，都会在输入空白字符后隐藏，删除后恢复。没有附件的纯空白草稿仍无法发送。[组件测试](../../../../packages/client/ui-conversation/tests/input-bar.client.spec.tsx) 覆盖显示、输入法组合、重新渲染和提交；[浏览器回归](../../../../apps/web/tests/composer-placeholder.e2e.ts) 使用构建后的界面检查键盘和剪贴板操作。

 An authenticated POST selects a declaration by viewed Session, event sequence, and original file index. The event carries no owning Session ID; relative paths in inherited history resolve against the viewed Session's workspace. The Host rechecks canonical workspace containment and regular-file existence before native opening. Route disposal cancels and awaits pending commands. The “Files changed” row lists successful file-tool mutations and retains its separate text-preview behavior. Its Chinese label is “本轮文件改动”; neither label implies final delivery.
 
+File cards separate default-app opening from file-manager navigation. The Host selects the file in Finder or Explorer, or opens its containing folder through the default Linux file manager. Both actions resolve the same saved declaration and recheck workspace containment; neither accepts a browser-supplied replacement path. Host-derived desktop metadata keeps remote-browser labels and availability honest, and the route enforces the configured availability on each gesture. A split button preserves one-click default-app opening while keeping the folder action explicit.
+
 ## Alternatives considered
 
 **Immutable attachment snapshots and editable temporary copies** preserve delivered versions after source edits or deletion, but make desktop edits diverge from workspace files and introduce retention work without a current product requirement. This decision supersedes the [snapshot-delivery design](../../archived/feature/2026-09-08-web-explicit-file-delivery.md). Neither a download endpoint nor a fallback copy remains; both require an explicit future product decision.

 The Client journal validates exact V3 event envelopes before publishing follow snapshots, live entries, or history pages. It reuses the browser-safe Session validators for required surface markers, exact replacement endpoints, earlier unique source seqs, embedded Assistant provenance, request-header omissions, and tool-error consistency. Invalid records fail without field stripping or normalization; range membership and source existence remain durable-log checks on the Host.
 
-Each endpoint states its activation policy. List reads only stored headers and projection-cache rows: it never calls per-session stat or opens a cold Session body. A current-format cache identity may supply every list hint; a lifecycle-matching predecessor cache may supply only its version-compatible title as a stale display fact, never as an authoritative fold seed. Search, attachment, history pages, log following, skill discovery, and workspace-path opening can inspect persistence without activating an Agent; `canOpenWorkspacePath()` reports native-opening availability without addressing a Session. Queue mutation and cancellation require live state; model, rename, prompt, and file-reference operations may resolve or resume an ordinary Session. Prompt rejects content with neither non-whitespace text nor an attachment before resolving the Agent or appending Session events; queue edits accept only non-empty text content. Prompt admission consumes opaque receipts from the injected [`fileUploads`](../../client/file-upload/README.md) Host service and resolves every same-Agent receipt before sending the complete ordered content list through `ctx.attachments`. Prompt retries whose `requestId` is already queued or logged return the original acceptance without inserting another message. Create and fork are the only operations that create a new Agent directly. 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. Queue mutation has one narrow exception: a live child whose current projected identity is continuable and comes from its own non-seed suffix accepts the ordinary Edit, Remove, and QueueDock Steer actions across both inbox destinations. One-shot, missing, unknown, corrupt, seed-only, or cold children remain rejected without resume. The skill catalog uses a live Agent when present or the recorded preset's standing scope when cold, so listing never starts an Agent.

The skill catalog uses a live Agent when present or the recorded preset's standing scope when cold, so listing never starts an Agent. The authenticated delivery routes use `workspaceDesktop()` for the serving Host name and file-manager behavior. `openWorkspacePath({ path, action: "reveal" })` delegates file-manager navigation to the native adapter; omitting `action` opens the default application.
 
 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`, `append`, and `settle-assistant` changes, and repairs reconnect or sequence gaps through a tail page. Backwards paging has two verbs: `loadOlder()` pulls one 50-message page, and `loadThrough(seq)` — the turn-jump loader — loops 200-message pages until the window covers the target seq, lowering a shared target on repeated calls, stopping on a page that makes no progress, and reporting busy through the same `loadingOlder` snapshot bit. The Web adapter explicitly opts into cursorless Assistant frames: each opening carries the active attempt's `startedAfterSeq`, `nextIndex`, and compact stream, and every stream member becomes a Client-only `assistant/live-chunk` entry ordered between durable cursors. The Host captures a follower-local arrival ordinal with that baseline and suppresses buffered frames at or before the cut; a replacement Agent may restart frame revision at one. A durable `assistant/message` or `assistant/attempt` arriving after an active opening stays staged only when its seq follows `startedAfterSeq` and its Turn and Step match; the matching end type, seq, and index publishes one named settlement delta that retires the attempt's transient rows and adds the durable entry while earlier same-step retries remain visible. Revision, dense-index, or settlement gaps for a known attempt reopen follow, while a controller that missed the start ignores unknown-attempt frames and publishes their durable settlement normally. An abandoned end publishes a settlement delta without a durable entry so its transient rows retire immediately. A durable gap-repair page has no Assistant baseline, so its held notification reopens follow once for a paired page and baseline. Every history record covers exactly its event seq. 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. For each inbox change, the Host publishes the projection frame first and derives the queue replacement from that same validated post-fold value, so listener registration order cannot produce a stale queue frame.Client Agent contexts provide the identity used by the independent [`fileUpload`](../../client/file-upload/README.md) service; Session objects expose lifecycle, prompt, queue, and history operations rather than file transfer.

 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`、`append` 与 `settle-assistant` 变更，并通过 tail page 修复重连或 seq 缺口。向后分页有两个动词：`loadOlder()` 拉一页 50 条 message，而 `loadThrough(seq)`——轮次跳转加载器——按 200 条 message 一页循环拉取直到窗口覆盖目标 seq，重复调用会下调共享目标，遇到无进展的页即停止，忙碌状态复用同一个 `loadingOlder` 快照位。Web adapter 显式选择接收无 cursor 的 Assistant frame：每个 opening 携带活跃 attempt 的 `startedAfterSeq`、`nextIndex` 与紧凑 stream，每个 stream member 都成为排在持久 cursor 之间的 Client-only `assistant/live-chunk` 条目。Host 会随该 baseline 捕获 follower 本地到达序号，并抑制该 cut 及之前的 buffered frame；replacement Agent 可以从 revision 一重新开始。活跃 opening 之后到达的持久 `assistant/message` 或 `assistant/attempt` 只有在其 seq 晚于 `startedAfterSeq` 且 Turn 与 Step 匹配时才会保持暂存；匹配的 end type、seq 与 index 会发布一个具名 settlement delta，删除该 attempt 的瞬态 row、加入持久条目，并保留同一步骤中更早的 retry。已知 attempt 的 revision、密集 index 或 settlement 缺口会重新打开 follow；若 controller 错过 start，则忽略 unknown-attempt frame，并正常发布其持久 settlement。Abandoned end 会发布不含持久条目的 settlement delta，使瞬态 row 立即退出。持久缺口修复 page 不携带 Assistant baseline，因此 held notification 会重新打开 follow 一次，以取得配对的 page 与 baseline。每条历史 record 只覆盖自身的 event seq。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。每次 inbox 变更时，Host 会先发布 projection frame，再从同一份已校验的折叠后值派生 queue replacement，因此监听器注册顺序不会产生陈旧的 queue frame。Client Agent context 提供独立 [`fileUpload`](../../client/file-upload/README.zh.md) 服务使用的身份；Session 对象提供生命周期、prompt、queue 与历史操作，不提供文件传输。

 The Node half registers the static `ui:deliverable-file-references` system-prompt section asking the model to mention primary files from successful creation or modification calls and to write those and any other changed-file references as Markdown inline code. The browser half registers a wrapper around `ProducedFiles` and explicit deliveries into the chat view's `conversation.chat.turnTail` hole. `deliverablesDefinition` folds each Turn's successful first-party mutation calls into `DeliverablesTurnData` from the validated raw arguments of `write`, `edit`, and mutating `str_replace_editor` commands. Reads, deletes, unsupported tools, malformed calls, and failed results contribute nothing. A new mutation tool needs an explicit Client contribution before it joins the list. The package also provides the `chatFileMentions` service the chat view consults per closing message; composing the plugin out removes both surfaces and leaves the view's empty chain at zero cost.

 ### Controls and icons
 
-The catalog above lists what each export is for; this section covers the behavior that props alone do not show. The `ic_ds_*` icon set and `FishLogo`/`BrandWordmark` marks fill brand and inline-icon slots. `LinkIcon` draws the leading category glyph for clickable artifact links — globe, folder, code, image, document, or plain paper, all riding `currentColor` — and `classifyLinkPath` derives a file path's category from its extension. `FileTypeIcon` is the one glyph that does not ride `currentColor`: its sheet colour is the type's identity, so a consumer that wants it muted (an empty state) applies `filter: grayscale(1)` itself. `classifyFileType` and `classifyLinkPath` read one extension vocabulary (`file-extensions.ts`), so a path classifies consistently on a link and on a sheet; the sheet is the finer of the two. `ConnectionIndicator` renders a warning-colored disconnected action, a connecting label whose one-to-three dots advance every 500ms independently of retry timing, or a success-colored recovered status. Hover or keyboard focus shows only the reconnect action label, including while the connecting dots animate. Every state reserves the widest supplied label and uses fixed icon and text columns, so copy changes do not move or resize the control. Its owner supplies visibility, the recovery hold, localized labels, and the immediate-reconnect callback; the primitive uses no native title tooltip. `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. `Toast` holds for the window its owner names through `holdMs`, because how long a banner has to stay depends on how much there is to read; the same value drives its unmount timer and the stylesheet's fade delay, so the two cannot disagree. `rankByName` is the `/` menu's shared candidate ranker for the command and skill sources: the query must be a case-insensitive ordered subsequence of the name; prefix hits rank first, then alignment score, then source order.

Callers must authorize the absolute file path before invoking either operation. Platform dispatch is covered by injected-runner tests; native desktop verification belongs to the corresponding platform.

 ### Explicit deliveries
 
-The Web `standard`, `ptc`, and `cordis` presets expose `present` for final workspace files, including files created through Bash. Call it with `files: [{ path, description? }]` after creating the files. The [present tool](../../fs/tool-present/README.md) owns file-count limits and Session declarations. The closing turn shows responsive cards with file names, types, descriptions, workspace paths, and a split Open button. Its primary action opens the source in the Host’s default application; the menu offers Show in Finder on macOS, Show in File Explorer on Windows and WSL, or Open containing folder through the default Linux file manager. The menu names the serving Host, independently of the browser’s operating system. Matching inline-code references open the same source files without starting a browser download. Repeated declaration of a path selects its latest description before the closing reply.
+The Web `standard`, `ptc`, and `cordis` presets expose `present` for final workspace files, including files created through Bash. Call it with `files: [{ path, description? }]` after creating the files. The [present tool](../../fs/tool-present/README.md) owns file-count limits and Session declarations. The closing turn shows responsive cards with file names, types, descriptions, workspace-relative paths, and a split Open button. Hovering the path shows its full location. Its primary action opens the source in the Host’s default application; the menu offers Show in Finder on macOS, Show in File Explorer on Windows and WSL, or Open containing folder through the default Linux file manager. The menu names the serving Host, independently of the browser’s operating system. Matching inline-code references open the same source files without starting a browser download. Repeated declaration of a path selects its latest description before the closing reply.
 
 The `present` tool row shows running, delivered, failed, or interrupted status; expanding a settled row reveals its recorded result. File cards include every delivered file. Both actions share pending state and show progress, acknowledgement, or an action-specific retryable error. A missing desktop disables both actions; a failed desktop-information read offers Retry. It requires a desktop and a suitable default application on the serving Host; a remote browser does not open applications on its own device.

 ### 显式交付
 
-Web 的 `standard`、`ptc` 与 `cordis` preset 提供 `present` 用于声明交付最终工作区文件，包括通过 Bash 创建的文件。创建文件后，以 `files: [{ path, description? }]` 调用。[present 工具](../../fs/tool-present/README.zh.md)拥有文件数量限制和 Session 声明。收尾 turn 显示响应式卡片，包含文件名称、类型、说明、工作区路径和分段“打开”按钮。主按钮在 Host 默认应用中打开源文件；菜单在 macOS 上提供“在 Finder 中显示”，在 Windows 和 WSL 上提供“在文件资源管理器中显示”，在 Linux 上通过默认文件管理器“打开所在文件夹”。菜单显示实际提供服务的 Host 名称，不依赖浏览器的操作系统。匹配的行内代码引用打开相同源文件，不触发浏览器下载。同一路径重复声明时，选择收尾回复之前最近一次的说明。

 `present` 工具行显示正在交付、已交付、失败或中断状态；展开已结束的调用可查看其记录的结果。文件卡片展示全部交付文件。两个操作共享等待状态，并显示进度、请求确认或各自可重试的错误。Host 没有桌面时禁用两个操作；桌面信息读取失败时提供“重试”。服务 Host 必须具备桌面和合适的默认应用；远程浏览器不会打开其所在设备上的应用。

-Browser-safe path helpers shared by Workspace-facing client and controller packages. The package joins Workspace-relative paths, abbreviates POSIX home directories for display, derives Workspace titles from POSIX or Windows paths, splits a path into its directories and final segment for display, and owns the `dsh-resource://file/…` address grammar that names a workspace file across the Sidebar and the resource model. It has no Cordis service or runtime state.

 The Web `standard`, `ptc`, and `cordis` presets expose `present` for final workspace files, including files created through Bash. Call it with `files: [{ path, description? }]` after creating the files. The [present tool](../../fs/tool-present/README.md) owns file-count limits and Session declarations. The closing turn shows responsive cards with file names, types, descriptions, workspace-relative paths, and a split Open button. Hovering the path shows its full location. Its primary action opens the source in the Host’s default application; the menu offers Show in Finder on macOS, Show in File Explorer on Windows and WSL, or Open containing folder through the default Linux file manager. The menu names the serving Host, independently of the browser’s operating system. Matching inline-code references open the same source files without starting a browser download. Repeated declaration of a path selects its latest description before the closing reply.
 
-The `present` tool row shows running, delivered, failed, or interrupted status; expanding a settled row reveals its recorded result. File cards include every delivered file. Both actions share pending state and show progress, acknowledgement, or an action-specific retryable error. A missing desktop disables both actions; a failed desktop-information read offers Retry. It requires a desktop and a suitable default application on the serving Host; a remote browser does not open applications on its own device.

Two updates are load-bearing rather than mechanical: telemetry's adoption tests assert that capture begins with the current lifecycle's newly appended boundary and excludes the constructor seed, and the property suite's replay invariant is "seed reproduced verbatim, plus one log-only boundary" with idempotence as its own property.

 **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: every event-body operation first runs the complete adjacent chain in memory and leaves the source path, bytes, and inode unchanged. Read handles may consume that current logical result directly; a write open exclusively publishes the final current generation under its canonical versioned filename before append. Header-only listing remains non-mutating and reports the numerically highest canonical generation. Catalog generation and module initialization reject a missing adjacent step, so a published first-party build never exposes a partial historical chain. Retained lower generations are not automatic fallback or a downgrade compatibility promise.
 
-**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).

 A source inherited count can be unknown before EOF: V2 derives it from seed markers, and V1→V2 can change cardinality. The chain passes that absence to the next stage instead of fabricating a count. The [V2-to-V3 inheritance rules](../../../../packages/session/session-format-v2-to-v3/README.md#sequence-references) support this case; older stages that require a header-supplied count still refuse when it is absent. This permits seeded multi-hop restoration without retaining an intermediate artifact array.
 
-All structural changes compose in the one unreleased V2→V3 edge; feature or review order does not allocate extra Session format versions. V0, V1, and V2 generations remain byte-frozen, and migration publishes only the final V3 successor. The unreleased target can evolve until release, but an already-written V3 file does not rerun its incoming migration. Integration tests therefore require isolated disposable homes and unchanged historical inputs rather than rewriting committed generations.
+V3 is a released Session format: [dsh-v0.1.5-alpha.1](https://github.com/deepseek-harness/deepseek-harness/releases/tag/dsh-v0.1.5-alpha.1) ships a [V3 writer](https://github.com/deepseek-harness/deepseek-harness/blob/dsh-v0.1.5-alpha.1/packages/core/session/src/types.ts#L88). An alpha product release still establishes a released persistence format. V0 through V3 retain their released semantics; committed generations remain byte-preserved during migration. A subsequent structural change requires the next adjacent edge under the [versioning rule](2026-08-10-session-log-version-mechanism.md), not an amendment to V2→V3. Ordinary event additions follow that rule’s required-event refusal mechanism rather than automatically allocating a version. An existing V3 file does not rerun its incoming migration; integration tests use isolated disposable homes and unchanged historical inputs.
 
 The [committed-corpus inventory](../../../../packages/test-support/llm-replay/tests/session-format-corpus-inventory.ts) identifies deliberately unsupported historical conversions by source path, generation, and exact refusal reason. Retaining those artifacts must not force chronology-changing migration or permit a blanket skip: every listed artifact must still raise the typed migration refusal, and unlisted artifacts must restore. Native current-generation fixtures cannot be classified as unsupported, because they do not traverse an incoming edge. Headerless test-harness protocol examples remain a separate explicit class. The corpus test checks source bytes after both successful and refused restoration; it does not rewrite historical evidence to satisfy the current reader.

-Use this tutorial to introduce a structural Session log version without rewriting released data. The worked example adds V3 through one V2→V3 edge, then lets independently reviewed changes extend that unreleased edge. Start with a working contributor checkout and read the [package checklist](adding-a-package.md), [format library](../../packages/session/session-format/README.md), and [released-format decision](../../.agents/notes/implemented/architecture/2026-08-31-released-session-format-migrations.md).
+Use this tutorial to introduce a future structural Session log version without rewriting released data. V3 is released and frozen. The worked example proposes V4 through one V3→V4 edge; it does not describe a shipped V4 package or runtime.

Ordinary event additions do not require a bump; follow the [versioning rule](../../.agents/notes/implemented/architecture/2026-08-10-session-log-version-mechanism.md). Distinguish the Session format integer from package release versions, SQLite schema versions, projection-unit versions, and protocol-wrapper versions.
 
-Use a shared `release/*` integration base, such as `release/session-log-v3`. The base change adds the V3 writer, codec, catalog wiring, identity migration, and verification. Create each independent child branch from that base and target its PR at the release branch, not another independent child's branch. Each child adds its own structural transformation, validators, consumers, and tests to the same `session-format-v2-to-v3` package. Do not introduce V4 or V5 just to represent review order. Merge reviewed children into the release branch through PRs, then validate the combined result before release. Honor release-branch force-push and deletion protections; do not force-sync it.

-Follow the package checklist to create a library, not a mounted plugin. An identity body conversion is only an initial wiring scaffold; the integrated [V2-to-V3 specification](../../packages/session/session-format-v2-to-v3/README.md#v2-to-v3-specification) defines the actual transformations and preservation rules. Do not treat its structural conversion as an identity edge.

-Declare `dsh.sessionFormatMigration` in the package manifest with `from: 2`, `to: 3`, an export path, and the exported migration, source codec, target codec, target-header validator, and target restorer.

 ## Durability contract
 
-What a persistence backend relies on: the durable log persists every event losslessly, and every Assistant attempt is one `assistant/message` or `assistant/attempt` whose embedded compact stream preserves the original timed chunks. `seq` stays contiguous across these settlements and all interleaved events. A backend may choose its own storage framing for an event batch as long as a handle's `read()` returns the exact appended events; current JSONL v2 writes one row per event (see [persistence.md](persistence.md)). All `event.data` must be JSON-serializable; `Session.append` enforces this at the source (throwing on non-serializable data), so a bad event never enters the log and `session.snapshotEvents()` always equals what a backend can persist. Adding an event type that carries non-serializable data, corrupts core execution nesting, or violates its owner's declared relation is a breaking change to the on-disk format.

 A successful v1 `assistant/message` must cite its complete ordered attempt. The migration removes the cited top-level chunks and obsolete message provenance, compacts the chunks without joining token boundaries, and stores the stream on that message. An unclaimed attempt becomes one log-only `assistant/attempt` at its final chunk position. Unrelated interleaved events keep their relative order.

-The seam's shared helpers validate current logical v1 records, and appends write only the current format ([rationale](../../../.agents/notes/implemented/architecture/2026-08-31-released-session-format-migrations.md)).

 ### Reading a card
 
-Each collapsed card uses the short module name as its primary title, shows the stable entry id underneath, and carries a small enablement tag; enabled entries also show a colored root-fiber status dot. Long entry ids truncate in the row and remain available on hover. Expanding one card reveals the declared entry id, the full module specifier, and the state facts: a preset row names the preset it comes from, its runtime status when the composition is live, and its disable condition when it carries one; a preset-provided global row explains that agent presets provide it per session, names the presets that enable it, and offers a jump into the preset group. Preset names resolve through the shared `presetDisplayText` fold (`dsh-agent-presets/display`) over [`ui-agent-preset`](../ui-agent-preset/README.md)'s dictionaries: shipped presets follow the active locale while user-authored ones keep their own metadata, so an English surface never echoes the preset files' Chinese names. Search filters both groups by module name and entry id.

The preset-provided marking is derived client-side: a global entry carries it when it is disabled there while at least one preset row for the same module specifier is actually enabled, so a module every preset gates off (or declares only conditionally) stays plainly disabled rather than over-claiming provision.

 ### Tool filtering is one live global-view rule

An in-process provider installs `ToolRuntime.restrict()` in the child's scope before publication, and the registry's single resolver applies the same result to wire tool schemas, lookup, execution, and PTC mode SDK generation. Independently registered system-prompt sections are outside `ToolRuntime`, so filtering a tool does not remove that plugin's standalone guidance.
+The tool filter controls capability visibility and executable lookup together. An in-process provider installs `ToolRuntime.restrict()` in the child's scope before publication, and the registry's single resolver applies the same result to wire tool schemas, lookup, execution, and PTC mode SDK generation. Independently registered system-prompt sections remain owned by their plugins. The filesystem, search, and web tool plugins use the existing `PromptSection.text({ scope })` callback and `ctx.tools.get(name, scope)` to omit guidance for unavailable tools and select applicable cross-tool text. This keeps the original wording and ordering for a supported tool set and works for any agent scope, including underlying PTC capabilities whose wire presentation is `run_code`. It adds no section-ownership metadata or assembly pass; unrelated static prose is not automatically rewritten by `restrict()`.
 
 Resolution follows these rules:

-工具过滤同时控制能力可见性和可执行查找。进程内提供方在发布前于子 agent 作用域中安装 `ToolRuntime.restrict()`，注册表的单一解析器对协议格式（wire format）的工具 schema、查找、执行和 PTC mode SDK 生成施加相同的结果。独立注册的系统提示词段落不在 `ToolRuntime` 内，因此过滤一个工具不会移除该插件的独立指导文本。
+工具过滤同时控制能力可见性和可执行查找。进程内提供方在发布前于子 agent 作用域中安装 `ToolRuntime.restrict()`，注册表的单一解析器对协议格式（wire format）的工具 schema、查找、执行和 PTC mode SDK 生成施加相同的结果。独立注册的系统提示词段落仍由各插件负责。文件系统、搜索和 Web 工具插件使用已有的 `PromptSection.text({ scope })` 回调与 `ctx.tools.get(name, scope)`，省略不可用工具的指导，并选择适用的跨工具文本。这会保留受支持工具集合下的原有措辞与顺序，适用于任意 agent scope，也包括协议呈现为 `run_code` 的底层 PTC 能力。该方式不新增段落归属元数据或组装步骤；`restrict()` 不会自动改写其他静态文字。
 
 解析遵循以下规则：

+You are an AI agent powered by DeepSeek Harness.
+
+You are a coding assistant powered by the deepseek-v4-flash model. Your working directory is {{cwd}}. Your bash tool runs under a file sandbox — a `[sandbox: file access denied …]` result is policy, not a command bug.
+
+Verify your work by running the code or tests. Keep answers brief and factual.
+
+
+Check the [exit code: N] marker on every bash result; investigate failures before moving on.
+
+Use the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.
+
+Track every background job id you start. You are notified in-session when a job finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running job's work. Before giving a final answer, collect every still-relevant job with job_output (set wait: true only when you are genuinely blocked on it), and job_kill jobs that stopped mattering.
+
+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.
+
+Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
+
+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.

Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under <mode> mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a job id immediately; read its output with `job_output` and stop it with `job_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later.",

The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return <value>` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise<any>` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object.

Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise<any[]>` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise<any[]>` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

 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.

Call it with `files: [{ path, description? }]` after creating the files. The [present tool](../../fs/tool-present/README.md) owns file-count limits and Session declarations. The closing turn shows responsive cards with file names, types, descriptions, workspace-relative paths, and a split Open button. Hovering the path shows its full location. Its primary action opens the source in the Host’s default application; the menu offers Show in Finder on macOS, Show in File Explorer on Windows and WSL, or Open containing folder through the default Linux file manager. The menu names the serving Host, independently of the browser’s operating system. Matching inline-code references open the same source files without starting a browser download. Repeated declaration of a path selects its latest description before the closing reply.

The closing turn shows one delivery as a full-width card and multiple deliveries in a grid of at most two cards per row. A list longer than four files starts collapsed and provides a control that reveals or hides the complete list.

+# Agent Note: Blocked weighted approvals remain pending
+
+Status: implemented
+
+English | [中文](2026-09-09-blocked-weighted-approvals-remain-pending.zh.md)
+
+## Problem
+
+The weighted approval commit status must distinguish an unmet merge condition from a failed policy evaluation. An effective `CHANGES_REQUESTED` review from a write-capable reviewer prevents a pull request from satisfying the approval policy, but it is a reversible review state rather than an evaluation failure.
+
+Publishing `failure` for that review state conflates the approval decision with the health of the publisher. It also treats one unmet policy condition differently from a draft pull request or insufficient approval points, which remain pending while contributors can resolve them.
+
+## Decision
+
+A completed weighted approval evaluation publishes `pending` when the pull request is a draft, has fewer than the required approval points, or has an effective `CHANGES_REQUESTED` review from a write-capable reviewer. A blocking review dominates the point total, so the status remains pending even when counted approvals reach the threshold.
+
+The evaluation publishes `success` only when the pull request is ready, the point threshold is met, and no blocking review exists. The separate `weighted approval publisher` Actions job reports whether evaluation and status publication completed. An evaluation failure publishes an `error` commit status and fails that job.
+
+## Verification
+
+[Approval policy tests](../../../../.github/review-ownership/check-approval.test.mjs) pin the threshold-reaching blocker case and the exact published `pending` payload. [Workflow tests](../../../../scripts/ci-workflow.spec.ts) pin the separate publisher job name.
+
+## Alternatives considered
+
+**Publish `failure` for a blocking review.** This keeps a visibly failed status until the review changes, but it represents an unmet and reversible merge condition as a malfunction and conflates policy outcome with publisher health.
+
+**Let approval points override a blocking review.** This makes the score the only success condition, but it permits a successful status while a write-capable reviewer's effective decision still requests changes.
+
+## Consequences
+
+Required-status branch rules block a pull request because `pending` does not satisfy the required status. Contributors can distinguish review work that remains from a failed approval evaluation, while the publisher job and `error` status retain the operational failure signal.
+
+Consumers do not receive a failed commit status solely because a blocking review exists. They must inspect the status description or effective reviews when they need to distinguish a blocker from other pending approval conditions.

+# Agent Note: 阻塞中的加权批准保持 pending
+
+Status: implemented
+
+[English](2026-09-09-blocked-weighted-approvals-remain-pending.md) | 中文
+
+## 问题
+
+`weighted approval` commit status 必须区分尚未满足的合并条件与失败的策略评估。具有写权限的评审人所提交且仍然生效的 `CHANGES_REQUESTED` 评审会阻止 PR 满足批准策略，但它是一种可撤销的评审状态，而不是评估故障。
+
+为这种评审状态发布 `failure` 会混淆批准决策与 publisher 的健康状态。它还会让一个尚未满足的策略条件区别于 draft PR 或批准点数不足；后两种情况在贡献者能够解决问题期间会保持 pending。
+
+## 决策
+
+完成的加权批准评估会在 PR 为 draft、批准点数少于要求，或具有写权限的评审人存在仍然生效的 `CHANGES_REQUESTED` 评审时发布 `pending`。阻塞性评审的优先级高于点数总和，因此即使计入的批准已经达到阈值，状态仍保持 pending。
+
+只有在 PR 已进入 ready 状态、达到点数阈值且不存在阻塞性评审时，评估才发布 `success`。独立的 `weighted approval publisher` Actions job 报告评估和状态发布是否完成。评估故障会发布 `error` commit status，并使该 job 失败。
+
+## 验证
+
+[批准策略测试](../../../../.github/review-ownership/check-approval.test.mjs)锁定已达到阈值但仍有 blocker 的场景，以及准确发布的 `pending` payload。[工作流测试](../../../../scripts/ci-workflow.spec.ts)锁定独立的 publisher job 名称。
+
+## 考虑过的替代方案
+
+**为阻塞性评审发布 `failure`。** 该方案会在评审改变之前保持明显的失败状态，但它会把尚未满足且可撤销的合并条件表示为故障，并混淆策略结果与 publisher 的健康状态。
+
+**允许批准点数覆盖阻塞性评审。** 该方案会让分数成为唯一的成功条件，但也允许在具有写权限的评审人仍然有效地要求修改时发布成功状态。
+
+## 后果
+
+需要该状态的分支规则会阻止 PR，因为 `pending` 不满足必需状态。贡献者可以区分尚待处理的评审工作与失败的批准评估，而 publisher job 和 `error` 状态保留运行故障信号。
+
+消费方不会仅因存在阻塞性评审而收到失败的 commit status。如果需要区分 blocker 与其他 pending 批准条件，它们必须检查状态描述或仍然生效的评审。

 ## Approval scoring
 
-The weighted approval workflow exposes two pull-request checks. The `weighted approval publisher` Actions job reports whether evaluation and status publication completed, while the `weighted approval` commit status carries the approval decision on the pull request head. Branch rules must require only the commit status with GitHub Actions as its expected source; a context-only requirement can accept a same-named status from another integration. A completed evaluation returns `success` at two approval points and `pending` below two points, while the pull request is a draft, or while a write-capable reviewer has an effective `CHANGES_REQUESTED` review. If evaluation fails, the publisher writes an `error` status.

 Reviewers whose calculated base repository permission is `write` or `admin` count. The [approval policy](approval-policy.json) gives `@07akioni`, `@imccyu`, `@tianyicui`, `@tianyicui-bot`, `@turtle1999`, and `@turtle2099` two points each; every other write-capable reviewer gets one point. The pull-request author and reviewers without write permission do not count.

They remain when `read` is hidden: the policy still guards mutations, and another observing operation, such as `str_replace_editor` with `command: view`, can establish the same file observation. Tool visibility does not disable that precondition.

 An authenticated POST selects a declaration by viewed Session, event sequence, and original file index. The event carries no owning Session ID; relative paths in inherited history resolve against the viewed Session's workspace. The Host rechecks canonical workspace containment and regular-file existence before native opening. Route disposal cancels and awaits pending commands. The “Files changed” row lists successful file-tool mutations and retains its separate text-preview behavior. Its Chinese label is “本轮文件改动”; neither label implies final delivery.
 
-File cards use the same split-control pattern as the Session header. The card and the left Open segment preview the source in the right Sidebar; the chevron opens the standard menu for default-app and file-manager actions. The Host selects the file in Finder or Explorer, or opens its containing folder through the default Linux file manager. Both native actions resolve the same saved declaration and recheck workspace containment; neither accepts a browser-supplied replacement path. Host-derived desktop metadata keeps remote-browser labels and availability honest, and the route enforces the configured availability on each native gesture. One delivery spans the row; multiple deliveries use at most two columns, retain every declaration, and collapse after the first four cards until the user expands the list.

Desktop metadata is invalidated with the connection generation so an old Host cannot keep native actions disabled or supply the wrong file-manager labels. Old metadata requests are cancelled and cannot replace the new generation’s response.

 The Web `standard`, `ptc`, and `cordis` presets expose `present` for final workspace files, including files created through Bash. Call it with `files: [{ path, description? }]` after creating the files. The [present tool](../../fs/tool-present/README.md) owns file-count limits and Session declarations. The closing turn shows one delivery as a full-width card and multiple deliveries in a grid of at most two cards per row. A list longer than four files starts collapsed and provides a control that reveals or hides the complete list. Each card shows the basename and description, or the file type when no description exists; a trailing parenthesized suffix in the description is omitted, and hovering the card replaces that line with the Sidebar-preview action. Clicking the card or the left side of its split Open control previews the file in the right Sidebar. The chevron opens the standard menu for the Host default application plus Show in Finder on macOS, Show in File Explorer on Windows and WSL, or Open containing folder through the default Linux file manager. Matching inline-code references open the same source files without starting a browser download. Repeated declaration of a path selects its latest description before the closing reply.
 
-The `present` tool row shows running, delivered, failed, or interrupted status; expanding a settled row reveals its recorded result. The collapsible card grid retains every delivered file. Both menu actions share pending state and show progress, acknowledgement, or an action-specific retryable error. Desktop information is read when delivery cards appear. A missing desktop disables the Open menu; a failed desktop-information read offers Retry. It requires a desktop and a suitable default application on the serving Host; a remote browser does not open applications on its own device.

Both menu actions share pending state and show progress, acknowledgement, or an action-specific retryable error. Desktop information is read when delivery cards appear and invalidated on connection replacement; responses from a replaced connection cannot publish metadata.

 ### Controls and icons
 
-The catalog above lists what each export is for; this section covers the behavior that props alone do not show. The `ic_ds_*` icon set and `FishLogo`/`BrandWordmark` marks fill brand and inline-icon slots. `LinkIcon` draws the leading category glyph for clickable artifact links — globe, folder, code, image, document, or plain paper, all riding `currentColor` — and `classifyLinkPath` derives a file path's category from its extension. `FileTypeIcon` is the one glyph that does not ride `currentColor`: its sheet colour is the type's identity, so a consumer that wants it muted (an empty state) applies `filter: grayscale(1)` itself. `classifyFileType` and `classifyLinkPath` read one extension vocabulary (`file-extensions.ts`), so a path classifies consistently on a link and on a sheet; the sheet is the finer of the two. `ConnectionIndicator` renders a warning-colored disconnected action, a connecting label whose one-to-three dots advance every 500ms independently of retry timing, or a success-colored recovered status. Hover or keyboard focus shows only the reconnect action label, including while the connecting dots animate. Every state reserves the widest supplied label and uses fixed icon and text columns, so copy changes do not move or resize the control. Its owner supplies visibility, the recovery hold, localized labels, and the immediate-reconnect callback; the primitive uses no native title tooltip. `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. `Toast` holds for the window its owner names through `holdMs`, because how long a banner has to stay depends on how much there is to read; the same value drives its unmount timer and the stylesheet's fade delay, so the two cannot disagree. `rankByName` is the `/` menu's shared candidate ranker for the command and skill sources: the query must be a case-insensitive ordered subsequence of the name; prefix hits rank first, then alignment score, then source order. `Button.segment` joins the start and end controls of a split action without changing standalone button geometry. `Menu.autoFocus` focuses its first enabled item, supports Arrow Up/Down and Home/End navigation, and restores the trigger on Escape; it is opt-in for action menus.

 ## Summary
 
-Use this tutorial to introduce a future structural Session log version without rewriting released data. V3 is released and frozen. The worked example proposes V4 through one V3→V4 edge; it does not describe a shipped V4 package or runtime. Start with a working contributor checkout and read the [package checklist](adding-a-package.md), [format library](../../packages/session/session-format/README.md), and [released-format decision](../../.agents/notes/implemented/architecture/2026-08-31-released-session-format-migrations.md).
+Use this tutorial to introduce the next structural Session log version without rewriting released data. Let N be the latest released Session format, verified from release evidence and source, and N+1 the target. V3 is released and frozen; the concrete V3→V4 example assumes N=3.

Create each independent child branch from that base and target its PR at the release branch, not another independent child's branch.

-To implement the proposed V3→V4 edge, follow the package checklist to create a library, not a mounted plugin. An identity body conversion is only an initial wiring scaffold. The released [V2-to-V3 specification](../../packages/session/session-format-v2-to-v3/README.md#v2-to-v3-specification) is an example of explicit transformations and preservation rules, not an edge to extend or treat as an identity conversion.

-In the proposed package manifest, declare `dsh.sessionFormatMigration` with `from: 3`, `to: 4`, an export path, and the exported migration, source codec, target codec, target-header validator, and target restorer. Reuse `releasedV3SessionFormatCodec` from the existing V2→V3 package and depend on that package; do not copy or redefine the released V3 codec. Export the proposed V4 codec and validators from the new package. Add the new edge as a direct dependency of the catalog and add the workspace's TypeScript paths and project references.

+## Problem
+
+Client feature plugins can share React components only through `@deepseek-ai/dsh-client-ui-primitives`, but file cards had no shared file-type presentation. `LinkIcon` owned the only extension table and deliberately collapsed paths into six link categories, while attachment cards, sent-message attachments, queued files, and workspace file rows used one generic document glyph. Two of those consumers also carried separate extension-display helpers. Adding a precise file icon anywhere else would have required another extension table or a runtime import between feature plugins.
+
+## Decision
+
+`ui-primitives` owns one Cordis-free file classification and rendering API. `fileExtension(path)` applies the shared basename and final-dot semantics to either path separator. `classifyFileType(path)` matches without case sensitivity and returns the closed `FileType` union: the traditional `code`, `excel`, `folder`, `html`, `image`, `markdown`, `other`, `pdf`, `ppt`, `video`, and `word` categories plus the detailed `CodeFileType` set imported from the supplied `square-code-icons` map. Exact filenames, filename prefixes, filename suffixes, optional project context, and extensions run in that order. The path classifier returns every member except `folder`; callers use the explicit `FileTypeIcon` `type` override when they know an entry is a directory. Unknown extensions, missing extensions, and trailing dots resolve to `other`, except the shared table recognizes named files such as `Dockerfile`, `Makefile`, `package.json`, `.gitignore`, `README`, and `CHANGELOG`.
+
+`FileTypeIcon` accepts a path, shared `IconProps`, the optional explicit type, and an optional project-file snapshot. Traditional file types render the supplied 28px document and folder contours as inline SVG. Excel, Markdown, PDF, PPT, and Word foreground marks scale to 122% around their visual center; the remaining marked traditional glyphs use 112%, while the file body and folded corner retain their source geometry and the generic file has no invented center mark. The sheet is a solid category color, the foreground mark and ordinary folded corner are white, and the generic file has a darker grey corner. CSS assigns the supplied category palette through static design tokens: DeepSeek blue for code/HTML/Markdown, the lighter DeepSeek blue for Word, green for Excel, two amber steps for folder/PPT, red for PDF, and neutral grey for unknown files. Image and video share the supplied violet through a component-local variable because the design platform has no matching violet token. A caller may override a traditional sheet through `--dsh-file-type-icon-color`.
+
+Recognized code and configuration files render the corresponding 20px square artwork scaled to the requested icon size. These technology marks retain their embedded multicolor fills and are the explicit exception to the ordinary current-color icon rule. The map selects React before TypeScript/JavaScript, Angular filename suffixes before their base extension, Docker/Node/Git/Make/CMake by filename rules, and Flutter only when the optional project snapshot contains a `pubspec.yaml` whose text includes `flutter:`. Markdown and SVG remain owned by the traditional Markdown and image categories. Every traditional and technology SVG is `aria-hidden`, and the card, row, or button that owns the file identity supplies the accessible name.
+
+`LinkIcon` delegates extension classification to `classifyFileType` and folds the detailed result into its existing link vocabulary: code and HTML use `code`, images use `image`, PDF/Word/Excel/PPT use `document`, and Markdown/video/unknown files use `other`. Extensionless names remain `other` in link contexts, so the 14px clickable-link appearance defined by the [clickable-link decision](2026-09-04-web-clickable-link-styles.md) does not change.
+
+Attachment upload cards, sent-message file cards, queued-file rows, and workspace file rows render `FileTypeIcon`. The two metadata rows use `fileExtension` rather than local parsers; a leading-dot basename such as `.env` therefore displays `ENV`, while an absent or trailing suffix displays no extension label. Image content continues to render as a preview rather than a file-type glyph, and produced-file links and Markdown file mentions continue to use `LinkIcon` because they are link surfaces.
+
+## Alternatives considered
+
+**Use `LinkIcon` for every file surface.** Rejected. Its six categories and 14px outline drawings communicate link destinations at text size; a 28px file card has room for the supplied HTML, Markdown, PDF, Word, Excel, PPT, and video identities.
+
+**Keep a second extension table beside `LinkIcon`.** Rejected. The same path could drift to different categories as either list grows. One detailed table plus an explicit detailed-to-link adapter preserves both consumers' semantics.
+
+**Put the supplied traditional-file colors directly in each SVG path.** Rejected. Traditional SVG geometry stays reusable and follows the icon set's `currentColor` rule; the component stylesheet owns the default category palette, and render sites retain one CSS-variable override instead of rewriting path fills. The technology artwork is exempt because its embedded multicolor marks identify the language or tool rather than decorating a generic file silhouette.
+
+**Add archive, audio, and data categories for symmetry.** Rejected. The supplied artwork and current consumers require no such glyphs. New `FileType` members require a shipped render site and artwork that remains legible at the 28px seat.
+
+## Testing
+
+The `ui-primitives` specs cover case-insensitive suffixes, both path separators, leading-dot files, missing and trailing suffixes, common named files, unknown fallback, all detailed code mappings, rule priority, Flutter context, every supplied technology SVG, instance-safe gradient ids, `aria-hidden`, sizing/class forwarding, distinct artwork, the 112% and 122% foreground-mark transforms, and the traditional solid-sheet/contrast-mark layers without literal SVG colors. A stylesheet spec pins every traditional category-to-color mapping, the caller override, and the local violet value. The existing `LinkIcon` classification table pins its coarse output, including `Makefile` remaining `other`. Attachment, chat, queue, and sidebar component suites exercise the migrated render paths; their accessibility output does not change because the glyphs remain decorative.
+
+## Consequences
+
+- Client packages use one filename parser and one detailed file-type table instead of importing or recreating feature-local logic.
+- A new suffix joins the detailed table only when an existing glyph truthfully represents it. If its link category differs from the current adapter, the change must also decide whether the 14px link appearance changes.
+- Code and configuration artwork preserves its embedded palette and does not accept the traditional `--dsh-file-type-icon-color` override.
+- The primitive owns no copy but does own the default file-type palette. Consumers continue to own accessible labels and surrounding text, and may replace the category color through `--dsh-file-type-icon-color`.
+- The detailed category names describe presentation, not MIME validation. A suffix is a display hint and does not establish file contents or trust.

+# Agent Note: 共享文件类型图标
+
+Status: implemented
+
+[English](2026-09-08-shared-file-type-icons.md) | 中文
+
+## 问题
+
+客户端功能插件只能通过 `@deepseek-ai/dsh-client-ui-primitives` 共享 React 组件，但文件卡片没有共享的文件类型呈现。`LinkIcon` 拥有唯一一份扩展名表，并有意把路径折叠为六种链接类别；附件卡片、已发送消息附件、排队文件和工作区文件行则统一使用一个通用文档图形。其中两个消费方还各自带着一份扩展名展示辅助函数。在其他位置增加精细文件图标，需要再复制一份扩展名表或让功能插件之间产生运行时 import。
+
+## 决策
+
+`ui-primitives` 统一拥有一套 Cordis-free 的文件分类与渲染 API。`fileExtension(path)` 对两种路径分隔符采用共享的 basename 与最终点号语义。`classifyFileType(path)` 不区分大小写，并返回闭合的 `FileType` 联合：传统的 `code`、`excel`、`folder`、`html`、`image`、`markdown`、`other`、`pdf`、`ppt`、`video`、`word` 类别，以及从所提供 `square-code-icons` 映射接入的细分 `CodeFileType` 集合。解析按完整文件名、文件名前缀、文件名后缀、可选项目上下文、扩展名的顺序执行。路径分类器返回 `folder` 之外的全部成员；调用方确认条目是目录时，通过 `FileTypeIcon` 的显式 `type` 覆盖指定目录。未知扩展名、无扩展名和末尾点号回退到 `other`，但共享表识别 `Dockerfile`、`Makefile`、`package.json`、`.gitignore`、`README`、`CHANGELOG` 等具名文件。
+
+`FileTypeIcon` 接受路径、共享 `IconProps`、可选的显式类型和可选的项目文件快照。传统文件类型把所提供的 28px 文档与文件夹轮廓渲染为 inline SVG。Excel、Markdown、PDF、PPT、Word 的前景标记围绕自身视觉中心缩放至 122%，其余带标记的传统图形使用 112%；文件底板与折角保持源图几何，通用文件不凭空增加中心标记。底板使用实色分类颜色，前景标记与普通折角使用白色，通用文件使用较深的灰色折角。CSS 通过静态设计 token 分配所提供的分类调色板：code/HTML/Markdown 使用 DeepSeek 蓝，Word 使用较浅的 DeepSeek 蓝，Excel 使用绿色，folder/PPT 使用两档琥珀色，PDF 使用红色，未知文件使用中性灰。image 与 video 通过组件本地变量共用所提供的紫色，因为设计平台没有匹配的紫色 token。调用方可通过 `--dsh-file-type-icon-color` 覆盖传统底板颜色。
+
+已识别的代码与配置文件把对应的 20px 方形图稿缩放到请求的图标尺寸。这些技术标记保留自身内嵌的多色填充，是普通 current-color 图标规则的明确例外。映射让 React 优先于 TypeScript/JavaScript、Angular 文件名后缀优先于基础扩展名，并按文件名识别 Docker/Node/Git/Make/CMake；只有可选项目快照包含内容带 `flutter:` 的 `pubspec.yaml` 时才选择 Flutter。Markdown 与 SVG 仍由传统 Markdown 和图片类别拥有。所有传统与技术 SVG 都是 `aria-hidden` 的，拥有文件身份的卡片、行或按钮提供无障碍名称。
+
+`LinkIcon` 委托 `classifyFileType` 做扩展名分类，再把精细结果折叠进原有链接词汇：code 与 HTML 使用 `code`，图片使用 `image`，PDF/Word/Excel/PPT 使用 `document`，Markdown、video 与未知文件使用 `other`。无扩展名文件在链接语境中仍是 `other`，因此[可点击链接决策](2026-09-04-web-clickable-link-styles.zh.md)定义的 14px 外观不变。
+
+附件上传卡片、已发送消息文件卡片、排队文件行和工作区文件行渲染 `FileTypeIcon`。两处元数据行使用 `fileExtension`，不再保留本地解析器；`.env` 这样的前导点 basename 会显示 `ENV`，无后缀或末尾点号则不显示扩展名 label。图片内容继续渲染为预览而不是文件类型图形，产物文件链接与 Markdown 文件提及继续使用 `LinkIcon`，因为它们属于链接表面。
+
+## 备选方案
+
+**所有文件表面都使用 `LinkIcon`。** 否决。它的六种类别和 14px outline 图形用于在文字尺寸下表达链接目标；28px 文件卡片有空间表达所提供的 HTML、Markdown、PDF、Word、Excel、PPT 与 video 身份。
+
+**在 `LinkIcon` 旁保留第二份扩展名表。** 否决。任一列表增长后，同一路径可能漂移到不同类别。一份精细表加一个显式的精细到链接适配，能同时保住两类消费方的语义。
+
+**把所提供的传统文件颜色直接写入每一条 SVG path。** 否决。传统 SVG 几何保持可复用，并遵守图标集的 `currentColor` 规则；组件样式表拥有默认分类调色板，渲染点只需一个 CSS 变量即可覆盖颜色，不需要重写 path 填充。技术图稿是例外，因为其内嵌的多色标记用于识别语言或工具，而不是装饰通用文件轮廓。
+
+**为了对称增加 archive、audio 与 data 类别。** 否决。提供的图稿与当前消费方都不需要这些图形。新增 `FileType` 成员必须有已发布的渲染点，以及在 28px slot 中仍可辨认的图稿。
+
+## 测试
+
+`ui-primitives` 测试覆盖不区分大小写的后缀、两种路径分隔符、前导点文件、无后缀与末尾点号、常见具名文件、未知回退、全部细分代码映射、规则优先级、Flutter 上下文、每一份技术 SVG、实例安全的渐变 id、`aria-hidden`、尺寸/class 转发、不同图稿、112% 与 122% 前景标记变换，以及不含 SVG 字面颜色的传统实色底板/对比标记层。样式表测试钉住每一项传统类别到颜色的映射、调用方覆盖变量与本地紫色值。既有 `LinkIcon` 分类表钉住它的粗粒度输出，包括 `Makefile` 仍为 `other`。附件、聊天、队列和侧边栏组件测试覆盖迁移后的渲染路径；由于图形仍是装饰性的，其无障碍输出不变。
+
+## 后果
+
+- 客户端包使用一个文件名解析器与一份精细文件类型表，不再 import 或重新实现功能包本地逻辑。
+- 新后缀只在已有图形能准确表达它时加入精细表。若它的链接类别与当前适配不同，这次改动还必须决定是否改变 14px 链接外观。
+- 代码与配置图稿保留内嵌调色板，不接受传统图形的 `--dsh-file-type-icon-color` 覆盖。
+- primitive 不拥有文案，但拥有默认文件类型调色板。消费方继续拥有无障碍 label 与周围文字，并可通过 `--dsh-file-type-icon-color` 替换分类颜色。
+- 精细类别名称描述展示意图，不是 MIME 校验。后缀只是展示提示，不能证明文件内容或可信度。

 ### Controls and icons
 
-The catalog above lists what each export is for; this section covers the behavior that props alone do not show. The `ic_ds_*` icon set and `FishLogo`/`BrandWordmark` marks fill brand and inline-icon slots. `LinkIcon` draws the leading category glyph for clickable artifact links — globe, folder, code, image, document, or plain paper, all riding `currentColor` — and `classifyLinkPath` derives a file path's category from its extension. `FileTypeIcon` is the one glyph that does not ride `currentColor`: its sheet colour is the type's identity, so a consumer that wants it muted (an empty state) applies `filter: grayscale(1)` itself. `classifyFileType` and `classifyLinkPath` read one extension vocabulary (`file-extensions.ts`), so a path classifies consistently on a link and on a sheet; the sheet is the finer of the two. `ConnectionIndicator` renders a warning-colored disconnected action, a connecting label whose one-to-three dots advance every 500ms independently of retry timing, or a success-colored recovered status. Hover or keyboard focus shows only the reconnect action label, including while the connecting dots animate. Every state reserves the widest supplied label and uses fixed icon and text columns, so copy changes do not move or resize the control. Its owner supplies visibility, the recovery hold, localized labels, and the immediate-reconnect callback; the primitive uses no native title tooltip. `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. `Toast` holds for the window its owner names through `holdMs`, because how long a banner has to stay depends on how much there is to read; the same value drives its unmount timer and the stylesheet's fade delay, so the two cannot disagree. `rankByName` is the `/` menu's shared candidate ranker for the command and skill sources: the query must be a case-insensitive ordered subsequence of the name; prefix hits rank first, then alignment score, then source order.
+The catalog above lists what each export is for; this section covers the behavior that props alone do not show. The `ic_ds_*` icon set and `FishLogo`/`BrandWordmark` marks fill brand and inline-icon slots. `FileTypeIcon` renders the traditional 28px Excel, folder, HTML, image, Markdown, generic, PDF, PPT, video, and Word glyphs, and uses the full-color square technology artwork for recognized code and configuration files. `classifyFileType` applies exact filename, prefix, suffix, optional project-context, and extension rules in that order; React names win over TypeScript/JavaScript, Angular suffixes win over their base extension, and a Dart file becomes Flutter only when the supplied project files contain a `pubspec.yaml` with `flutter:`. Markdown and SVG remain traditional Markdown and image files. `fileExtension` exposes the same basename and final-dot parsing for adjacent metadata labels. Traditional glyphs use a solid category-colored sheet with a white mark and translucent white corner; the generic file uses a grey sheet and darker grey corner. Callers may override the sheet color through `--dsh-file-type-icon-color`. The full-color technology artwork is the deliberate exception and retains its embedded palette. All glyphs are decorative and carry no label. `LinkIcon` remains the smaller leading glyph for clickable artifact links — globe, folder, code, image, document, or plain paper — while `classifyLinkPath` folds the shared file types into that existing six-category vocabulary. `ConnectionIndicator` renders a warning-colored disconnected action, a connecting label whose one-to-three dots advance every 500ms independently of retry timing, or a success-colored recovered status. Hover or keyboard focus shows only the reconnect action label, including while the connecting dots animate.

Its owner supplies visibility, the recovery hold, localized labels, and the immediate-reconnect callback; the primitive uses no native title tooltip. `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. `Toast` holds for the window its owner names through `holdMs`, because how long a banner has to stay depends on how much there is to read; the same value drives its unmount timer and the stylesheet's fade delay, so the two cannot disagree. `rankByName` is the `/` menu's shared candidate ranker for the command and skill sources: the query must be a case-insensitive ordered subsequence of the name; prefix hits rank first, then alignment score, then source order.

 ## 概述
 
-使用 `dsh-client-ui-primitives`，通过共享 React UI 构建 Web 客户端控件并渲染 agent 输出。它提供标准控件、图标、锚定浮层，以及用于带 TeX 公式的 Markdown、终端输出、文件读取、差异、搜索、网页检索和 JSON 的渲染器。这些渲染器会丢弃原始 HTML、限制链接并解析 ANSI 转义序列，以处理不受信任的模型输出。调用方必须提供本地化 label；这些组件仅依赖 React 和 `--dsw-*` 设计 token。

 ### 控件与图标
 
-上面的目录说明每个导出的用途；本节讲 props 本身看不出来的行为。`ic_ds_*` 图标集与 `FishLogo`/`BrandWordmark` 标记填充品牌与行内图标 slot。`LinkIcon` 为可点击产物链接绘制前置分类图形——地球、文件夹、代码、图片、文档或纸张，全部随 `currentColor`——`classifyLinkPath` 按扩展名推导文件路径的类别。`FileTypeIcon` 是唯一不随 `currentColor` 的字形：纸片颜色就是类型的身份，需要压灰的使用方（空状态）自行加 `filter: grayscale(1)`。`classifyFileType` 与 `classifyLinkPath` 读同一份扩展名词表（`file-extensions.ts`），一条路径在链接上与纸片上的归类一致；纸片分得更细。`ConnectionIndicator` 可渲染警告色的断联操作、以独立于 retry 时序的 500ms 节奏推进一至三个点的连接中状态，或成功色的恢复状态。悬停或键盘聚焦时只显示重连操作文案，连接中的圆点动画也保持隐藏。所有状态都为最长的输入 label 预留空间，并使用固定的图标列和文字列，因此文案变化不会移动控件或改变其宽度。它的 owner 提供可见性、恢复驻留时间、本地化 label 与立即重连回调；该原语不使用原生 title tooltip。`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。 `Toast` 的停留时长由使用方通过 `holdMs` 指定，因为横幅该留多久取决于有多少内容要读；同一个值同时驱动它的卸载定时器与样式表的淡出延迟，两者不可能再错位。 `rankByName` 是 `/` 菜单命令源与 skill 源共享的候选排序器：查询必须是名字的不区分大小写的有序子序列；前缀命中排最前，其次按对齐分数，再按来源顺序。

 ## Decision
 
-The [present tool](../../../../packages/fs/tool-present/README.md) declares existing regular files inside the calling Session's workspace. It records paths and optional descriptions without reading or copying contents. The [deliverables plugin](../../../../packages/client/ui-deliverables/README.md) opens current workspace sources in the Host's default application. Edits are visible on the next open; deletion or movement makes the declaration unavailable. File-content preservation and copy-on-write storage are deferred until a persistence design owns them.
+The [present tool](../../../../packages/fs/tool-present/README.md) declares existing regular source files under the [Session filesystem access policy](2026-09-09-present-filesystem-access.md). It records paths and optional descriptions without reading or copying contents. The [deliverables plugin](../../../../packages/client/ui-deliverables/README.md) opens current workspace sources in the Host's default application. Edits are visible on the next open; deletion or movement makes the declaration unavailable. File-content preservation and copy-on-write storage are deferred until a persistence design owns them.
 
 The tool description requires `present` after writing a file the user asked to receive and before the final response, including files created through Bash or code execution. A prose path reference does not replace the call. The recorded [SVG delivery scenario](../../../../snapshots/web/present-svg/snapshot.yml) uses a user request that does not name `present`, and checks the resulting file, delivery event, and card. Its UI snapshot covers the expanded Chat transcript; navigation and composer controls belong to their own scenarios, so unrelated chrome changes cannot invalidate file-delivery expectations.
 
 The tool remains an ordinary package with shared filesystem and tool error classes. Its pure type entry owns the delivery event without importing Host code into the browser. The `standard`, `ptc`, and `cordis` presets mount it; `minimal` retains its two tools. Each plugin instance correlates its executions with successful final `tools/result` notifications before appending `deliverables/presented`. Native and nested calls share this rule. A later enclosing program failure does not revoke a completed nested declaration; blocked results publish none, and same-name scoped replacements cannot publish another instance's results.
 
-An authenticated POST selects a declaration by viewed Session, event sequence, and original file index. The event carries no owning Session ID; relative paths in inherited history resolve against the viewed Session's workspace. The Host rechecks canonical workspace containment and regular-file existence before native opening. Route disposal cancels and awaits pending commands. The “Files changed” row lists successful file-tool mutations and retains its separate text-preview behavior. Its Chinese label is “本轮文件改动”; neither label implies final delivery.

-File cards use the same split-control pattern as the Session header. The card and the left Open segment preview the source in the right Sidebar; the chevron opens the standard menu for default-app and file-manager actions. The Host selects the file in Finder or Explorer, or opens its containing folder through the default Linux file manager. Both native actions resolve the same saved declaration and recheck workspace containment; neither accepts a browser-supplied replacement path. Host-derived desktop metadata keeps remote-browser labels and availability honest, and the route enforces the configured availability on each native gesture. One delivery spans the row; multiple deliveries use at most two columns, retain every declaration, and collapse after the first four cards until the user expands the list. Desktop metadata is invalidated with the connection generation so an old Host cannot keep native actions disabled or supply the wrong file-manager labels. Old metadata requests are cancelled and cannot replace the new generation’s response.

+# Agent Note: Present follows Session filesystem access
+
+Status: implemented
+
+English | [中文](2026-09-09-present-filesystem-access.zh.md)
+
+## Problem
+
+Generated files commonly live outside the workspace, especially in `/tmp`. Workspace containment rejects files that the Session filesystem and Sidebar already allow. A provider process path may also name a remote file rather than a file on the serving Host.
+
+## Decision
+
+`present` accepts existing regular files accessible through its composed `ctx.fs`, with relative paths resolved against the Session working directory. There is no workspace containment check or special temporary-directory allowlist. Missing files, directories, final symbolic links, and provider failures reject the declaration. A sandbox's private temporary files remain unavailable when the filesystem provider cannot see them.
+
+Native actions resolve or resume the viewed Session's Agent and use its `workspaceFiles.stat`. The resulting canonical process path must map from a Host path back to the same process path through that Agent's filesystem. Absent or different mappings produce 422 and a localized Sidebar-preview suggestion. This conservatively supports Host paths that share their canonical process spelling; providers with only a nonidentity Host mapping can still serve previews. A same-named local file never substitutes for an unmapped provider file.
+
+This replaces the workspace-only access rule in the [source-file delivery decision](2026-09-08-present-workspace-source-files.md). That note continues to own content-free declarations, Session events, and editing current sources. The request still selects only saved Session/event/file coordinates, never an arbitrary browser-supplied path.
+
+## Alternatives considered
+
+A `/tmp` allowlist excludes other readable output locations and duplicates filesystem policy. Treating every provider process path as a Host path can open an unrelated local file. Adding a generic inverse path-mapping API or copying remote files expands provider and retention responsibilities beyond source-file delivery.
+
+## Consequences
+
+Workspace files, accessible temporary files, Downloads, and files in another project use the same declaration rules. Native opening requires both a serving desktop and a verified Host path. Metadata checks do not make a desktop application's later path lookup atomic.
+
+Focused tests cover external absolute and relative paths, final symbolic links, missing files, Session lookup failures, absent and mismatched Host mappings, and localized native-unavailable state. Existing recorded Web scenarios retain declaration, preview, native action, and content-free export coverage.

+# Agent Note：Present 遵循 Session 文件系统访问规则

+Status: implemented
+
+[English](2026-09-09-present-filesystem-access.md) | 中文
+
+## 问题
+
+生成文件经常位于工作区外，尤其是 `/tmp`。工作区包含检查会拒绝 Session 文件系统和侧栏已经允许访问的文件。提供方的进程路径也可能指向远端文件，而非服务 Host 上的文件。
+
+## 决策
+
+`present` 接受所组合的 `ctx.fs` 可访问的已有普通文件，相对路径按 Session 工作目录解析。不检查工作区包含关系，也不另设临时目录白名单。文件缺失、为目录、最终路径为符号链接或提供方出错时，声明失败。文件系统提供方不可见的沙箱私有临时文件仍不可用。
+
+原生操作查找或恢复当前查看的 Session 的 Agent，并调用其 `workspaceFiles.stat`。得到的规范化进程路径必须能通过该 Agent 的文件系统从 Host 路径映射回同一进程路径。映射缺失或不同会返回 422，并显示使用侧栏预览的本地化提示。这只支持规范化后与进程路径写法相同的 Host 路径；仅支持不同写法的 Host 映射的提供方仍可提供预览。没有映射时，本机同名文件不能替代提供方文件。
+
+本决策替代[源文件交付决策](2026-09-08-present-workspace-source-files.zh.md)中只允许工作区文件的访问规则。原说明继续负责不保存内容的声明、Session 事件和编辑当前源文件。请求仍只按已保存的 Session、事件和文件索引选择文件，不接受浏览器提供的任意路径。
+
+## 考虑过的替代方案
+
+`/tmp` 白名单会排除其他可读的输出位置，并重复文件系统策略。把所有提供方进程路径都视作 Host 路径可能打开不相关的本机文件。增加通用反向路径映射 API 或复制远端文件，会让提供方与文件保留承担源文件交付之外的职责。
+
+## 影响
+
+工作区文件、可访问的临时文件、Downloads 和其他项目中的文件使用相同的声明规则。原生打开同时要求服务主机有可用桌面和经过验证的 Host 路径。元数据检查不能使桌面应用随后按路径打开文件的操作具有原子性。
+
+定向测试覆盖工作区外的绝对和相对路径、最终符号链接、文件缺失、Session 查询失败、Host 映射缺失或不一致，以及本地化的原生操作不可用状态。已有的 Web 录制场景继续覆盖声明、预览、原生操作和不含文件内容的导出。

 ### Explicit deliveries
 
-The Web `standard`, `ptc`, and `cordis` presets expose `present` for final workspace files, including files created through Bash. Call it with `files: [{ path, description? }]` after creating the files. The [present tool](../../fs/tool-present/README.md) owns file-count limits and Session declarations. The closing turn shows one delivery as a full-width card and multiple deliveries in a grid of at most two cards per row. A list longer than four files starts collapsed and provides a control that reveals or hides the complete list. Each card shows the basename and description, or the file type when no description exists; a trailing parenthesized suffix in the description is omitted, and hovering the card replaces that line with the Sidebar-preview action. Clicking the card or the left side of its split Open control previews the file in the right Sidebar. The chevron opens the standard menu for the Host default application plus Show in Finder on macOS, Show in File Explorer on Windows and WSL, or Open containing folder through the default Linux file manager. Matching inline-code references open the same source files without starting a browser download. Repeated declaration of a path selects its latest description before the closing reply.

 The `present` tool row shows running, delivered, failed, or interrupted status; expanding a settled row reveals its recorded result. The collapsible card grid retains every delivered file. Both menu actions share pending state and show progress, acknowledgement, or an action-specific retryable error. Desktop information is read when delivery cards appear and invalidated on connection replacement; responses from a replaced connection cannot publish metadata. Selecting a native menu action returns keyboard focus to the available Sidebar Open button. Pending actions close the menu until another explicit gesture. A missing desktop disables the Open menu; a failed desktop-information read offers Retry. It requires a desktop and a suitable default application on the serving Host; a remote browser does not open applications on its own device.

 The Node half registers the static `ui:deliverable-file-references` system-prompt section asking the model to mention primary files from successful creation or modification calls and to write those and any other changed-file references as Markdown inline code. The browser half registers a wrapper around `ProducedFiles` and explicit deliveries into the chat view's `conversation.chat.turnTail` hole. `deliverablesDefinition` folds each Turn's successful first-party mutation calls into `DeliverablesTurnData` from the validated raw arguments of `write`, `edit`, and mutating `str_replace_editor` commands. Reads, deletes, unsupported tools, malformed calls, and failed results contribute nothing. A new mutation tool needs an explicit Client contribution before it joins the list. The package also provides the `chatFileMentions` service the chat view consults per closing message; composing the plugin out removes both surfaces and leaves the view's empty chain at zero cost.
 
-Native opening uses an authenticated POST addressed by the viewed Session, event sequence, and original file index. The Host resolves the declaration against that Session’s workspace and checks the current file exists within it before launching either native action. The same configured desktop availability governs metadata and execution. Edits affect subsequent opens; deletion returns an error. No file-content copy or attachment is created.

+Native opening uses an authenticated POST addressed by the viewed Session, event sequence, and original file index. The Host resolves or resumes that Session’s Agent and checks the declaration through its `workspaceFiles.stat`, using the same filesystem as Sidebar previews. Native actions require the canonical process path to map from a Host path back to that same process path. Providers without this mapping return 422 and the card directs the user to Sidebar preview; a same-named Host file is insufficient. The same configured desktop availability governs metadata and execution. Edits affect subsequent opens; deletion returns an error. No file-content copy or attachment is created.

 ### Controls and icons
 
-The catalog above lists what each export is for; this section covers the behavior that props alone do not show. The `ic_ds_*` icon set and `FishLogo`/`BrandWordmark` marks fill brand and inline-icon slots. `LinkIcon` draws the leading category glyph for clickable artifact links — globe, folder, code, image, document, or plain paper, all riding `currentColor` — and `classifyLinkPath` derives a file path's category from its extension. `FileTypeIcon` is the one glyph that does not ride `currentColor`: its sheet colour is the type's identity, so a consumer that wants it muted (an empty state) applies `filter: grayscale(1)` itself. `classifyFileType` and `classifyLinkPath` read one extension vocabulary (`file-extensions.ts`), so a path classifies consistently on a link and on a sheet; the sheet is the finer of the two. `ConnectionIndicator` renders a warning-colored disconnected action, a connecting label whose one-to-three dots advance every 500ms independently of retry timing, or a success-colored recovered status. Hover or keyboard focus shows only the reconnect action label, including while the connecting dots animate. Every state reserves the widest supplied label and uses fixed icon and text columns, so copy changes do not move or resize the control. Its owner supplies visibility, the recovery hold, localized labels, and the immediate-reconnect callback; the primitive uses no native title tooltip. `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. `Toast` holds for the window its owner names through `holdMs`, because how long a banner has to stay depends on how much there is to read; the same value drives its unmount timer and the stylesheet's fade delay, so the two cannot disagree. `rankByName` is the `/` menu's shared candidate ranker for the command and skill sources: the query must be a case-insensitive ordered subsequence of the name; prefix hits rank first, then alignment score, then source order. `Button.segment` joins the start and end controls of a split action without changing standalone button geometry. `Menu.autoFocus` focuses its first enabled item, supports Arrow Up/Down and Home/End navigation, and focuses the first button in the anchor on Escape; it is opt-in for action menus.

The `ic_ds_*` icon set and `FishLogo`/`BrandWordmark` marks fill brand and inline-icon slots. `LinkIcon` draws the leading category glyph for clickable artifact links — globe, folder, code, image, document, or plain paper, all riding `currentColor` — and `classifyLinkPath` derives a file path's category from its extension. `FileTypeIcon` is the one glyph that does not ride `currentColor`: its sheet colour is the type's identity, so a consumer that wants it muted (an empty state) applies `filter: grayscale(1)` itself. `classifyFileType` and `classifyLinkPath` read one extension vocabulary (`file-extensions.ts`), so a path classifies consistently on a link and on a sheet; the sheet is the finer of the two. `ConnectionIndicator` renders a warning-colored disconnected action, a connecting label whose one-to-three dots advance every 500ms independently of retry timing, or a success-colored recovered status. Hover or keyboard focus shows only the reconnect action label, including while the connecting dots animate. Every state reserves the widest supplied label and uses fixed icon and text columns, so copy changes do not move or resize the control. Its owner supplies visibility, the recovery hold, localized labels, and the immediate-reconnect callback; the primitive uses no native title tooltip. `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. `Toast` holds for the window its owner names through `holdMs`, because how long a banner has to stay depends on how much there is to read; the same value drives its unmount timer and the stylesheet's fade delay, so the two cannot disagree. `rankByName` is the `/` menu's shared candidate ranker for the command and skill sources: the query must be a case-insensitive ordered subsequence of the name; prefix hits rank first, then alignment score, then source order. `Menu.autoFocus` focuses its first enabled item, supports Arrow Up/Down and Home/End navigation, and focuses the first button in the anchor on Escape; it is opt-in for action menus.

 - **Append-only; a crashed turn is closed, never truncated.** Flushed events are never rewritten. The [semantic checkpoint policy](../../../../packages/session/session-checkpoint-policy/README.md) drains the request before model dispatch, a recorded top-level call before tool dispatch, and the complete response/result batch after a step; the loop drains the final turn boundary. Because one interrupted turn may contain substantial valid work, persistence returns its contiguous, parseable events unmodified; the reader owns balancing — resume computes risk-classified error results for unanswered assistant calls, a missing `step/end`, and `turn/end` with `{ kind: 'interrupted' }` (`interruptedTurnClosers`) and appends them through its write handle, while read-only observers add the same closers in memory. The synthetic results keep resumed provider transcripts valid. Only the incomplete fragment of a torn final append is discarded — complete records recovered from it are durably rewritten by the write path before its first new append; a parse error or sequence gap in the committed prefix is corruption and makes the session unloadable.
 - **The file backend is canonical while the service remains extensible.** `dsh-session-persistence-jsonl` is the sole first-party provider and passes `runPersistenceContract`; the abstract service remains available to out-of-tree providers. The [JSONL-only persistence decision](../simplification/2026-08-30-jsonl-only-session-persistence.md) owns removal of the first-party database provider and its deliberate compatibility cut.
 - **Metadata is out-of-log.** Format version, cwd, and lineage are storage concerns, not replayable conversation state, so they live in a `SessionHeader` owned by `dsh-session` and attached to a `Session` via a new readonly `session.header` — never in `SessionEventMap`, never reaching `deriveMessages()`. `createdAt` is non-negative safe-integer Unix epoch milliseconds: live creation and persistence registration reject fractional values, and JSONL validates the decoded header. The alternative (a merge-extensible `session/meta` event as log line 0) was rejected: an in-log event would ride along with a seeded/forked session for free, but metadata is not replayable state, so the explicit out-of-log header boundary is the cleaner cost. (The header was originally split into an immutable `SessionHeader` plus a mutable `SessionSummary` whose union was `SessionMeta`; the mutable summary was later removed as dead state — see [Drop the mutable session summary](../../archived/simplification/2026-06-19-drop-mutable-session-summary.md).)

 Each key choice above records its rejected alternative where the choice is stated: a **stream-filtered canonical log** — loses attempt evidence, while removing events without an explicit migration breaks contiguous sequence numbers; **truncating a crashed turn** — silently destroys a long autonomous run's real work; an **in-log `session/meta` event as log line 0** — metadata is not replayable state; **finite fractional `createdAt` values** — have no producer and diverge from integer Unix-millisecond storage; **hard-injecting `sessionPersistence` into the loop** — would pend non-persistent demos forever.
 
-Format versioning: the header carries a `version`; handles expose only `SESSION_FORMAT_VERSION = 2`. JSONL event-body reads compose the static v0-to-v1 and v1-to-v2 adjacent migration chain before returning a handle; the first edge owns bounded legacy normalization, while the second owns Assistant stream embedding and dense reference remapping. V0 remains at suffixless `session.jsonl[.zstd]`, while positive versions use immutable lowercase `session.vN.jsonl[.zstd]` names ([released Session migration](2026-08-31-released-session-format-migrations.md)).

 - **文件后端为规范实现，服务保持可扩展。** `dsh-session-persistence-jsonl` 是唯一 first-party provider，并通过 `runPersistenceContract`；抽象服务继续供仓库外 provider 使用。[JSONL-only 持久化决策](../simplification/2026-08-30-jsonl-only-session-persistence.zh.md)负责 first-party 数据库 provider 的删除及其明确 compatibility cut。
 - **元数据在日志之外。** 格式版本、cwd 和谱系是存储关注点，不是可回放的对话状态，因此它们存放在 `dsh-session` 拥有的 `SessionHeader` 中，并通过新的只读属性 `session.header` 附加到 `Session` 上——永远不进入 `SessionEventMap`，永远不到达 `deriveMessages()`。`createdAt` 是以 Unix epoch 毫秒表示的非负安全整数：运行时创建和持久化注册会拒绝小数值，JSONL 会验证解码后的 header。替代方案（一个可合并扩展的 `session/meta` 事件作为日志第 0 行）被否决：日志内事件会自然随 seed/fork 的会话携带，但元数据不是可回放状态，因此显式的日志外 header 边界是更清晰的取舍。（header 最初被拆分为不可变的 `SessionHeader` 加可变的 `SessionSummary`，二者的联合类型为 `SessionMeta`；可变 summary 后来因属于死状态而被移除——见 [移除可变会话摘要](../../archived/simplification/2026-06-19-drop-mutable-session-summary.md)。）

 The alpha v0-to-v1 edge owns a frozen complete released-v0 event and payload inventory. It refuses every unknown historical event type before target staging, including an event marked `ignorable: true`, and refuses unexpected members of known payloads except fields explicitly classified as owner-opaque JSON. Merge-extensible nested discriminants remain part of that explicit policy: unknown content-block types, message-source kinds, assistant finish-reason kinds, and turn-ending reason kinds are preserved as owner-opaque JSON, while known arms receive structural validation. The diagnostic names the event type, its sequence number, and the unchanged source generation.

Ordinary current-format reading retains the established envelope behavior: an unknown required event refuses, while an unknown event carrying `ignorable: true` remains readable.

 A source inherited count can be unknown before EOF: V2 derives it from seed markers, and V1→V2 can change cardinality. The chain passes that absence to the next stage instead of fabricating a count. The [V2-to-V3 inheritance rules](../../../../packages/session/session-format-v2-to-v3/README.md#sequence-references) support this case; older stages that require a header-supplied count still refuse when it is absent. This permits seeded multi-hop restoration without retaining an intermediate artifact array.
 
-V3 is a released Session format: [dsh-v0.1.5-alpha.1](https://github.com/deepseek-harness/deepseek-harness/releases/tag/dsh-v0.1.5-alpha.1) ships a [V3 writer](https://github.com/deepseek-harness/deepseek-harness/blob/dsh-v0.1.5-alpha.1/packages/core/session/src/types.ts#L88). An alpha product release still establishes a released persistence format. V0 through V3 retain their released semantics; committed generations remain byte-preserved during migration. A subsequent structural change requires the next adjacent edge under the [versioning rule](2026-08-10-session-log-version-mechanism.md), not an amendment to V2→V3. Ordinary event additions follow that rule’s required-event refusal mechanism rather than automatically allocating a version. An existing V3 file does not rerun its incoming migration; integration tests use isolated disposable homes and unchanged historical inputs.
+The [version and release-status reference](../../../../docs/session-format-status.md) owns the published-format record and identifies the code’s writer authority.

 The [committed-corpus inventory](../../../../packages/test-support/llm-replay/tests/session-format-corpus-inventory.ts) identifies deliberately unsupported historical conversions by source path, generation, and exact refusal reason. Retaining those artifacts must not force chronology-changing migration or permit a blanket skip: every listed artifact must still raise the typed migration refusal, and unlisted artifacts must restore. Native current-generation fixtures cannot be classified as unsupported, because they do not traverse an incoming edge. Headerless test-harness protocol examples remain a separate explicit class. The corpus test checks source bytes after both successful and refused restoration; it does not rewrite historical evidence to satisfy the current reader.

 A dsh verification installs the vendored family's pack output too. The harness packages declare the vendored framework as a peer, those packages live in another sequence, and the credential-free job cannot fetch them from a private registry — so the dsh `pack` job packs the vendored family for verification while publishing only the dsh set. The publish workflow (`release-publish.yml`) repacks the current tree and publishes only the dsh set.

Each fixture binds loopback port `0`, lets the operating system allocate and bind the port atomically, and maps the recorded URL or endpoint through the real provider to that listener.

Ordinary event additions do not require a bump; follow the [versioning rule](../../.agents/notes/implemented/architecture/2026-08-10-session-log-version-mechanism.md). Distinguish the Session format integer from package release versions, SQLite schema versions, projection-unit versions, and protocol-wrapper versions.
 
-For the V3→V4 example, use a shared `release/*` integration base, such as `release/session-log-v4`. The base change adds the V4 writer, codec, catalog wiring, identity migration, and verification. Create each independent child branch from that base and target its PR at the release branch, not another independent child's branch. Each child adds its structural transformation, validators, consumers, and tests to the example's `session-format-v3-to-v4` package. Do not introduce V5 or V6 just to represent review order. Merge reviewed children into the release branch through PRs, then validate the combined result before release. Honor release-branch force-push and deletion protections; do not force-sync it.

 Use disposable, isolated Harness homes for unreleased N+1 integration testing. An interim N+1 file already has the target writer version, so a later edit to N→N+1 will not migrate that file again. Re-run from unchanged historical input in a fresh test home; never repair this by rewriting a committed generation or reusing a real user's home.

-To implement the example V3→V4 edge, follow the package checklist to create a library, not a mounted plugin. An identity body conversion is only an initial wiring scaffold. The released [V2-to-V3 specification](../../packages/session/session-format-v2-to-v3/README.md#v2-to-v3-specification) is an example of explicit transformations and preservation rules, not an edge to extend or treat as an identity conversion.

-In the example package manifest, declare `dsh.sessionFormatMigration` with `from: 3`, `to: 4`, an export path, and the exported migration, source codec, target codec, target-header validator, and target restorer. Reuse `releasedV3SessionFormatCodec` from the existing V2→V3 package and depend on that package; do not copy or redefine the released V3 codec. Export the example's V4 codec and validators from the new package. Add the new edge as a direct dependency of the catalog and add the workspace's TypeScript paths and project references.

 Implement `transformEvent(event, context)`, `transformRun(run, context)`, and `finish(context)`. Emit synchronously through `context.emitEvent` or `context.emitRun`; a call can produce zero, one, or many outputs. Let a stage consume codec-owned compact runs directly, or iterate `run.expand()` without materializing an intermediate array. The caller owns scheduling, and the chain finishes upstream stages before downstream stages.
 
-Treat the inherited cut as a logical event count, not a physical row count. Expose `headerInheritedEventCount` only when it is known before EOF; `finish` returns the exact target cut. A preceding cardinality-changing edge can make that count unavailable at construction. Derive it from validated seed markers when required, and test the example's V0→V1→V2→V3→V4, V1→V2→V3→V4, and V2→V3→V4 chains with seeded Sessions, not just direct V3 input.

A change to structure or event positions requires classifying source events, payload members, and references, and explicitly deciding whether opaque data can remain valid.

+## Summary
+
+Use this reference to distinguish the checkout’s Session writer version from the latest published Session format. The code constant owns the writer version; the release record below owns the latest released format and its publication evidence. Other documentation links here instead of restating which version is current, next, or unreleased.

+## Sources of truth
+
+- **Checkout writer:** `SESSION_FORMAT_VERSION` in [core Session types](../packages/core/session/src/types.ts) is the only hand-maintained current-writer number in code. The [catalog generator](../scripts/gen-session-format-catalog.ts) derives codec ordering and checks that adjacent migrations reach it. A package version, codec export name, fixture filename, or projection-cache version is not the writer authority.
+- **Latest released format:** `latestReleasedVersion` in the following record identifies the published Session format. `evidenceTag` names a published product release whose tagged writer has that value; it need not be the first release carrying the format. The bilingual copy is checked against the same record, not maintained as a separate decision.
+- **Release status:** compare the writer constant with the verified release record. Equality means the writer format has shipped. A greater writer version is a development target beyond the recorded release. A lower writer version means this checkout predates that release. No separate released boolean is maintained. Before declaring a greater version unreleased, verify that no published release has advanced the record.
+
+An alpha, beta, or release-candidate product publication establishes released Session-format obligations. GitHub’s prerelease flag does not make persisted user data disposable. A missing release record is not evidence of non-publication. The [versioning rule](../.agents/notes/implemented/architecture/2026-08-10-session-log-version-mechanism.md) owns compatibility decisions; [released-format migration](../.agents/notes/implemented/architecture/2026-08-31-released-session-format-migrations.md) owns immutable generations and adjacent conversion.

+
+Evidence: [published release](https://github.com/deepseek-harness/deepseek-harness/releases/tag/dsh-v0.1.5-alpha.1) and [its tagged writer source](https://github.com/deepseek-harness/deepseek-harness/blob/dsh-v0.1.5-alpha.1/packages/core/session/src/types.ts).

+## Updating the record
+
+When a structural writer change is implemented, update the code constant and adjacent catalog together; do not advance this release record before publication. When a product release first publishes a higher Session format, confirm publication and its tagged writer, then advance this record and both evidence links in the same bilingual update. Later product releases carrying the same format do not require changing the record. Never lower it on the development trunk.
+
+The [documentation-standard test](../scripts/doc-standard.spec.ts) checks record structure, bilingual equality, evidence-link consistency, and that the documented release does not exceed the checkout writer. This keyless check does not query GitHub or prove that the record is up to date; publication verification remains part of the release update.
+
+Use “current format” and “next adjacent version” for general behavior. Keep explicit numbers for fixed migration inputs and outputs, wire schemas, historical evidence, and tests of those particular versions. The [format-version cookbook](cookbook/adding-a-session-format-version.md) uses N for the verified latest released format and N+1 for its successor.

+# Session 格式版本与发布状态
+
+[English](session-format-status.md) | 中文
+
+## 概述
+
+本参考区分工作区的 Session 写入器版本与最新已发布的 Session 格式。代码常量拥有写入器版本；下方发布记录拥有最新已发布格式及其发布证据。其他文档链接到这里，而不重复声明哪个版本是当前、下一个或尚未发布的版本。
+
+## 目录
+
+- [单一真源](#sources-of-truth)
+- [发布记录](#release-record)
+- [更新记录](#updating-the-record)
+- [开发备注](#dev-note)
+
+<a id="sources-of-truth"></a>
+## 单一真源
+
+- **工作区写入器：**[核心 Session 类型](../packages/core/session/src/types.ts)中的 `SESSION_FORMAT_VERSION` 是代码中唯一手工维护的当前写入器版本号。[目录生成器](../scripts/gen-session-format-catalog.ts)推导 codec 顺序，并检查相邻迁移是否到达该版本。包版本、codec 导出名称、fixture（测试前置数据）文件名或投影缓存版本都不是写入器版本的权威来源。
+- **最新已发布格式：**下方记录中的 `latestReleasedVersion` 标识已发布的 Session 格式。`evidenceTag` 指定一个已发布的产品版本，其标签对应的写入器具有该值；它不必是首次携带该格式的发布。双语副本按同一记录校验，不作为独立决策维护。
+- **发布状态：**比较写入器常量与已核实的发布记录。相等表示写入器格式已经发布。写入器版本更高表示它是超出记录中发布版本的开发目标。写入器版本更低表示该工作区早于该发布。不另行维护 released 布尔值。在声明更高版本尚未发布前，必须核实是否已有产品发布推进了记录。
+
+产品的 alpha、beta 或 release-candidate 发布都会确立已发布 Session 格式的义务。GitHub 的 prerelease 标记不会让持久化用户数据成为可丢弃数据。缺少发布记录不代表尚未发布。[版本规则](../.agents/notes/implemented/architecture/2026-08-10-session-log-version-mechanism.zh.md)拥有兼容性决策；[已发布格式迁移](../.agents/notes/implemented/architecture/2026-08-31-released-session-format-migrations.zh.md)拥有不可变代际与相邻转换规则。
+
+<a id="release-record"></a>
+## 发布记录
+
+```yaml session-format-release
+latestReleasedVersion: 3
+evidenceTag: dsh-v0.1.5-alpha.1
+```
+
+证据：[已发布产品版本](https://github.com/deepseek-harness/deepseek-harness/releases/tag/dsh-v0.1.5-alpha.1)及[对应标签的写入器源码](https://github.com/deepseek-harness/deepseek-harness/blob/dsh-v0.1.5-alpha.1/packages/core/session/src/types.ts)。
+
+<a id="updating-the-record"></a>
+## 更新记录
+
+实现结构性写入器变更时，一起更新代码常量与相邻迁移目录；不要在产品发布前推进此发布记录。当产品首次发布更高的 Session 格式时，确认发布事实及对应标签的写入器，然后在同一次双语更新中推进本记录与两个证据链接。后续携带相同格式的产品发布无需改变此记录。开发主干上的记录绝不降低。
+
+[文档标准测试](../scripts/doc-standard.spec.ts)检查记录结构、双语一致性、证据链接一致性，以及文档中的已发布版本不高于工作区写入器。这个无密钥检查不会查询 GitHub，也不能证明记录是最新的；核实发布事实仍属于发布更新的一部分。
+
+一般行为使用“当前格式”和“下一条相邻版本”等表述。固定迁移的输入与输出、协议 schema、历史证据及针对特定版本的测试保留明确版本号。[格式版本实操手册](cookbook/adding-a-session-format-version.zh.md)用 N 表示已核实的最新发布格式，用 N+1 表示其后继版本。

 A fresh fork constructor requires its seed to equal the inherited prefix and appends `session/end-seed { inherited: true }` at the exact durable cut. A restore retains that tagged marker and appends an ordinary `session/end-seed {}` only when its complete stored seed does not already end in a marker. Both forms are log-only and produce no message; `Session`'s constructor is the only legitimate writer.
 
-For fork lineage, locate the LAST marker whose payload carries `inherited: true`; v2 decoding requires it exactly when `SessionHeader.isSeeded` is true and derives `inheritedEventCount` from its seq.

 It exists because seed history and live work are otherwise byte-identical, which defeats any plugin owning a standalone open/close bracket: an unmatched `compaction/start` reads the same whether the writer crashed mid-compaction or is compacting right now. An opening marker before `session/end-seed` came from the constructor seed and belongs to an ended lifecycle, whatever ended it (a crash, a succeeding process, or a fork out of a still-running parent), so its owner may treat it as dead. That covers only brackets *this* session inherited: a concurrently live session holding an open bracket over the same history has its own boundary elsewhere, so tolerating concurrent writers needs a liveness signal beyond the log. Core writes the boundary and reads nothing from it — a bracket's vocabulary stays with its owning plugin, which is why crash repair closes turn/step/tool boundaries and never `compaction/*`.

 它之所以必要，是因为种子历史与实时工作在字节层面完全相同，这会让任何拥有独立开／闭括号的插件失效：一个未配对的 `compaction/start`，无论写入方是在压缩中途崩溃、还是此刻正在压缩，读起来都一样。在 `session/end-seed` 之前的开启标记来自构造种子，并且属于一个已结束的生命周期，无论结束原因为何（崩溃、进程接替，或从仍在运行的父会话 fork 出来），因此其所有方可以视之为已死。这只覆盖*本*会话继承的括号：另一个并发存活的会话可能在同一段历史上持有开放括号，而它自己的边界在别处，因此容忍并发写入方还需要日志之外的存活信号。核心写入该边界但不从中读取任何内容——括号的词汇表仍归其所属插件，这也正是崩溃修复只关闭轮次／步骤／工具边界而从不处理 `compaction/*` 的原因。

 - **Snapshot** (`pnpm run test:snapshot`): a top-level scenario's highest recorded parent generation supplies user input and model replay, then serves as the expected persisted result. Parent filenames are `session[.vN].jsonl`; child roles are `session.<ordinal>[.vN].jsonl`; v0 omits `.v0`, positive versions require lowercase `.vN`, and each filename must agree with its header. 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 for plugin CSS.
 
-Session fixtures retain headers and payloads but omit body sequence/time envelopes; replay synthesizes them. Replay, record, and refresh select each parent/child role's highest generation. Current V3 uses `.v3`, one row per event, and embedded compact Assistant streams.

 ## Summary
 
-`dsh-session-persistence-jsonl` stores each session in a current append-only JSONL log and retains immutable historical format generations — checksummed Zstandard frames by default, raw newline-delimited lines when compression is disabled. It serves the current logical `SessionEvent` stream through persistence handles, so format migration, compression, historical decoding, and crash recovery remain storage-internal details. Choose it when consumers need a per-session file on disk; the logs are readable as plain lines when `compression: 'none'` is selected. A root directory is the one required configuration; durability, lazy materialization, released-v0/v1 migration, and torn-tail crash recovery come with the backend.

 Each recorded-session directory carries a closed `snapshot.yml` manifest plus canonical parent and contiguous child roles. Parent filenames are `session[.vN].jsonl`; children are `session.<ordinal>[.vN].jsonl`; v0 omits `.v0`, positive versions use lowercase `.vN`, and every filename agrees with its header. A role may retain older generations, but the harness selects the numerically highest one. An owning manifest may declare `sessionFormat.version` plus one or more closed `coverage` names to keep that historical generation as an explicit migration fixture; absence tracks the current writer. The manifest also 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. Storage guards check tool results and portable paths in every selected parent and child role. Prompt/schema scrubbing, message identity, and prompt-before-request ordering apply to current generations; retained predecessors keep their historical representation. The adapter registers expected-output, Session-log, and optional `workspace.expected/` comparisons; guards reject orphan directories, missing roles, noncanonical names, absolute paths, malformed manifests, and platform-specific separators.
 
-`normalizeSessionSnapshot` retains the complete Session header and event payloads but omits top-level `seq`/`time` envelopes from committed fixtures after normalizing paths and scrubbing system-prompt text and tool schemas; it also normalizes embedded stream clocks and historical packed-row `seq0`/`time0` envelopes, and catalog child-creation clocks. Event order and source-event references are preserved. Replay synthesizes the top-level envelopes in memory, while runtime persistence continues to write complete logs. Multi-session comparison validates expected and harvested logs through the strict build-static Session format catalog before identity redaction and normalization; source filenames cannot alter format validation. A retained historical replay input is not the native V3 writer-output oracle: structural migration preserves request meaning but can produce a different event layout. Normalization preserves unexpected request-header fields, including `system`, so regressions remain visible. Versionless protocol-adapter unit fixtures remain outside the released Session format corpus. Current v3 fixtures use one row per event; retained v0/v1 fixtures may use canonical packed rows.

 Spill scenarios save through the real local provider under a private temporary root. Their fixture adapter exposes fixed-length logical locators and maps only this run’s saved locators back to real files for retrieval, preserving preview budgets without writing into a shared logical path. Known snapshot spill paths normalize to stable locator tokens, including paths quoted inside JSON omission notices with JSON-escaped Windows separators. Refresh extraction preserves the matched serialized path spelling for literal replacement. Normalization changes only the locator: saved byte lengths and omission counts remain comparison evidence.
 
-Retained historical scenarios keep their canonical Session files unchanged and selected for replay, with no canonical V3 sibling in the pinned directory. Their exact normalized native V3 output is recorded separately in `writer.expected.jsonl` for the parent and `writer.<ordinal>.expected.jsonl` for children; these are output oracles, not replay generations. Retained SDK scenarios use `notifications.current.expected.jsonl` for current protocol output. Comparisons neither project current events back into a historical format nor strip structural differences. Independent migration tests verify the official transform rather than treating native writer layout as its expected event sequence.

Scenarios with an explicit `sessionFormat` remain read-only in record mode. `pnpm run test:snapshot:refresh` stays keyless, runs the selected highest replay input, and writes stdout, owned prompt and tool-schema sidecars, and a fresh current-generation comparable Session output; retained historical scenarios write the separate writer-output oracles instead of a canonical V3 replay generation.

@@ -18,6 +18,12 @@ Session logs must be upgradable after release, and the runtime that ships first
 
 **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 four `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).
 
+### Writer and publication authority
+
+`SESSION_FORMAT_VERSION` owns the checkout writer number; the [release-status reference](../../../../docs/session-format-status.md) owns one bilingual `latestReleasedVersion` and `evidenceTag` record. Publication changes independently of source development, so status is derived by comparing those facts rather than maintaining a second `released` boolean. General documentation links to these authorities; fixed-version contracts and historical evidence keep their explicit numbers.
+
+The [documentation-standard check](../../../../scripts/doc-standard.spec.ts) validates record structure, bilingual equality, evidence-link consistency, and the local release/writer ordering without network access. It proves internal consistency, not publication or freshness. The release operator verifies publication and updates the record after a higher format ships, as required by the [release process](../process/2026-08-10-npm-release-sequences.md). This keeps compatibility review independent of credentials and GitHub availability while making the manual freshness obligation explicit.
+
 ## 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, JSONL, and the BFF wire schema. V1 adds the static adjacent catalog, the identity v0-to-v1 edge, header-only descriptors, exact-generation JSONL publication, and current-only restoration described in [Released Session formats](2026-08-31-released-session-format-migrations.md). [Historical Session read preparation](2026-09-05-read-only-session-migration-preparation.md) owns the JSONL timing between in-memory restoration and write publication. V2 keeps the physical codec neutral to ordinary event vocabulary and payload additions: the adjacent edge freezes its released source and target inventories, while equal-version restoration applies the installed known-event set and current payload semantics. First-party writers do not set `ignorable` through `Session.append`, while a repository-external plugin is a current consumer; equal-version retention lives in the [external-plugin retention decision](2026-08-30-retain-ignorable-external-session-events.md), and the stricter historical rule lives in the [alpha migration refusal decision](2026-08-31-alpha-historical-unknown-event-refusal.md). The unknown-type guard remains read-side because append-time vocabulary refusal would stall a live session's durability. JSONL classifies foreign versions from the minimal raw header before current-header or event parsing, so a structurally different future format reports the upgrade direction instead of "corrupt".
@@ -28,3 +34,5 @@ What shipped in v0 (release 0812): direction-aware refusal with the raw-log path
 - **Default-ignorable unknown events** — inverts the failure mode of a forgotten marker from visible over-refusal into silent corruption.
 - **Migrating during header-only listing** — makes cheap inventory mutate storage and requires event bodies to compute facts that a header cannot prove. Listing returns descriptors; event-body reads own publication.
 - **Per-plugin runtime registration of known event types** — rejected because it would make the known set composition-dependent and register event names without classifying whether omission is safe. The persisted `ignorable` marker keeps that classification with each record; the [external-plugin retention decision](2026-08-30-retain-ignorable-external-session-events.md) owns the current consumer constraint.
+- **Duplicate release flags or runtime status services** — introduce another mutable authority for a maintainer fact that does not control Session execution. The writer constant and publication record suffice.
+- **Network-dependent documentation gates or publication automation** — network queries would couple local documentation checks to credentials and GitHub availability; a runtime service or publication workflow change is unnecessary for record consistency. Publication verification remains an explicit release-operator obligation.

 **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：模型可见内容只经四种带 `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、JSONL 和 BFF 线上 schema 接受。V1 添加静态相邻 catalog、恒等 v0-to-v1 迁移边、仅 header descriptor、精确代际 JSONL 发布与[已发布 Session 格式](2026-08-31-released-session-format-migrations.zh.md)定义的当前专用恢复。[历史 Session 只读迁移准备](2026-09-05-read-only-session-migration-preparation.zh.md)负责内存恢复与写入发布之间的 JSONL 时序。V2 让物理 codec 对普通事件词汇与 payload 新增项保持中立：相邻迁移边冻结 released source 与 target 清单，同版本恢复则应用已安装的 known-event set 与当前 payload 语义。第一方 writer 不通过 `Session.append` 设置 `ignorable`，而一个仓库外插件仍依赖该字段；同版本保留由[外部插件保留决策](2026-08-30-retain-ignorable-external-session-events.zh.md)定义，更严格的历史规则由 [alpha 迁移拒绝决策](2026-08-31-alpha-historical-unknown-event-refusal.zh.md)定义。未知类型守卫仍只在读取侧生效，因为 append 时的词汇拒绝会中断活跃 Session 的持久化。JSONL 会在当前 header 或事件解析前从最小原始 header 分类外来版本，因此结构完全不同的未来格式会报告升级方向而不是"损坏"。

 Scenario-owned HTTP fixtures separate the stable authority recorded in the session from their transport listener. Each fixture binds loopback port `0`, lets the operating system allocate and bind the port atomically, and maps the recorded URL or endpoint through the real provider to that listener. Any process-global transport interception matches only the recorded endpoint, is owned by the fixture fiber, and is restored before the listener closes.

 The `present` tool row shows running, delivered, failed, or interrupted status; expanding a settled row reveals its recorded result. The collapsible card grid retains every delivered file. Both menu actions share pending state and show progress, acknowledgement, or an action-specific retryable error. Desktop information is read when delivery cards appear and invalidated on connection replacement; responses from a replaced connection cannot publish metadata. Selecting a native menu action returns keyboard focus to the available Sidebar Open button. Pending actions close the menu until another explicit gesture. A missing desktop disables the Open menu; a failed desktop-information read offers Retry. It requires a desktop and a suitable default application on the serving Host; a remote browser does not open applications on its own device.

Subject: [PATCH 098/164] feat(client): polish sidebar and file preview
 interactions

Seed sidebar default pages lazily on expansion, scope page-tab dedupe
to the target pane, let a sole tab split its own pane with a factory
backfill, close menus when focus enters a sandboxed iframe, and pin the
code preview copy banner while unifying its background with the pane.

+# Agent Note: Sidebar and preview interaction polish
+
+Status: implemented

+
+## Problem
+
+Five small interaction defects around the right Sidebar and the document preview. Every session's surface was born with a seeded default page, so a collapsed column the user never opened already held a page, and the first open into a fresh surface showed the seed beside the content it opened. Page tabs deduplicated surface-wide: opening a page whose tab sat in the other pane pulled focus across panes instead of opening it where asked. Dragging a pane's sole tab onto its own edge did nothing, though the user plainly asked for a split. A dropdown over the HTML preview did not dismiss on a click inside the sandboxed iframe, because that pointerdown never reaches the parent document. And the code preview's copy banner and card background scrolled away under horizontal scrolling, while the code kept the chat card's gray fill instead of sitting on the pane's own background.
+
+## Decision
+
+**Default pages seed lazily.** `createSurface` in [stores.ts](../../../../packages/client/ui-sidebar-right/src/client/stores.ts) mints a collapsed, empty surface; the store's `advance` passes the seed factory to `planSettle` only when the intent leaves the column expanded. The expansion that would first show an empty layout is what seeds the then-current default page, and closing the last closable tab collapses the column and leaves the layout empty until the next expansion. The [last-tab close rule](2026-09-08-sidebar-last-tab-close-rules.md) and [default-page selection](2026-09-08-sidebar-default-pages.md) stay as decided; only the seeding moment moved.
+
+**Page uniqueness is pane-scoped.** The guide-only merge generalized to every page kind (`pageKind`/`panePage`): opening a page focuses an existing tab only inside the pane the open targets, and a page dragged, dropped, or docked into a pane already showing that kind's page merges into the pane's own. Resource tabs keep the kit's surface-wide reveal.
+
+**A sole tab splits its own pane when a factory backfills it.** `planDropTab` in [planner.ts](../../../../packages/client/ui-dockkit/src/engine/planner.ts) takes an optional `TabFactory`; with one, the previously refused self-edge release splits, the factory's tab backfills the vacated pane before the move so the dragged tab ends focused. Without a factory the release still changes nothing.
+
+**Menus close on focus entering an iframe.** [Menu.tsx](../../../../packages/client/ui-primitives/src/Menu.tsx) adds a window `blur` listener gated on `document.activeElement instanceof HTMLIFrameElement` — the focus move is the only signal a pointerdown inside a cross-origin iframe leaves, and the gate keeps app or tab switches from closing the list.
+
+**The code preview pins its banner and drops the card fill.** With wrap off, [CodeBody.module.css](../../../../packages/client/ui-sidebar-documentpreview/src/client/code/CodeBody.module.css) sizes the renderer `max-content` so the sticky banner has the full scroll width to ride, and pins the banner `sticky; left: 0; width: 100cqw` against the document scroller (`container-type: inline-size` on the preview body). The shared CodeBlock's fill is routed through a new `--dsl-code-block-background` variable (default unchanged, so chat keeps its gray card) and the shared banner carries an inert `data-code-block-banner` hook; the preview sets the variable to `transparent` so code sits on the pane's own background.
+
+## Alternatives considered
+
+**Keep seeding at surface creation.** A collapsed column held a page nobody asked for, and the seed took slot 0 of every fresh surface ahead of the first real open.
+
+**Keep surface-wide page dedupe.** Focus jumped to the other pane on an explicit "open here", the exact complaint that started the change.
+
+**A bare window-blur close for menus.** Closes the list on every app or tab switch; the `activeElement` gate scopes the close to the one case the document cannot see.
+
+**An inner code scroller for the horizontal axis.** Restoring `overflow-x: auto` on the `pre` keeps the banner still, but puts the horizontal scrollbar at the bottom of the whole block — unreachable in a long file — and both axes deliberately live in the document owner's scroller.
+
+## Consequences
+
+`planDropTab`'s factory parameter is new kit API any embedder may pass; `planSettle` already accepted an absent factory, which now also names the Sidebar's collapsed-state behavior. The `--dsl-code-block-background` variable and `data-code-block-banner` attribute are the code block's owner-styling seam; no shared stylesheet rule targets the attribute. Kit planner specs cover the backfilled self-split and its focus order; Sidebar store, service, and seat specs cover lazy seeding, pane-scoped page merges, and the empty collapsed layout; a Menu spec covers the gated blur close. The `ui-sidebar-right`, `ui-dockkit`, and `ui-sidebar-documentpreview` READMEs restate the rules.

+# Agent Note: 侧边栏与文件预览交互打磨
+
+Status: implemented
+
+[English](2026-09-09-sidebar-and-preview-interaction-polish.md) | 中文
+
+## Problem
+
+右侧边栏与文档预览周边的五个小交互缺陷。每个会话的停靠面出生时就播种默认页，于是用户从未打开过的折叠列里已经躺着一个页面，向全新停靠面的第一次打开会让种子页出现在所开内容旁边。页 tab 在整个停靠面范围去重：打开一个页时，若它的 tab 在另一格里，焦点会被拽到那一格，而不是在被要求的格里打开。把一个格的唯一 tab 拖到本格边缘什么都不发生，尽管用户明明要的是分栏。HTML 预览上方的下拉菜单在点击沙箱 iframe 内部时不消失，因为那次 pointerdown 根本到不了父文档。代码预览的复制条和卡片背景会被横向滚动甩开，而且代码保留了会话卡片的灰色填充，而不是坐在分栏自身的背景上。
+
+## Decision
+
+**默认页惰性播种。**[stores.ts](../../../../packages/client/ui-sidebar-right/src/client/stores.ts) 的 `createSurface` 铸造一个折叠且为空的停靠面；store 的 `advance` 只在意图让列保持展开时才把种子工厂传给 `planSettle`。首次会展示空布局的那次展开播种彼时的默认页；关闭最后一个可关 tab 时收起整列，布局保持为空直到下次展开。[最后一个 tab 的关闭规则](2026-09-08-sidebar-last-tab-close-rules.zh.md)与[默认页选择](2026-09-08-sidebar-default-pages.zh.md)维持原决定；改变的只是播种时机。
+
+**页唯一性以格为界。**只对引导页的合并规则推广到每种页 kind（`pageKind`/`panePage`）：打开一个页只在这次打开的目标格内聚焦既有 tab；把页拖入、放入或收回到已展示该 kind 页的格会并入该格自己的 tab。资源 tab 保留套件的全停靠面聚焦。
+
+**有工厂回填时，唯一 tab 可对本格分栏。**[planner.ts](../../../../packages/client/ui-dockkit/src/engine/planner.ts) 的 `planDropTab` 接受可选 `TabFactory`：带工厂时，先前被拒绝的本格边缘释放会分栏，工厂的 tab 先于移动回填腾出的格，因此被拖的 tab 最终保持聚焦。不带工厂时该释放仍不改变任何东西。
+
+**焦点进入 iframe 时关闭菜单。**[Menu.tsx](../../../../packages/client/ui-primitives/src/Menu.tsx) 增加 window `blur` 监听，以 `document.activeElement instanceof HTMLIFrameElement` 为门：焦点移动是跨源 iframe 内 pointerdown 留下的唯一信号，这道门也让应用或标签页切换不会误关列表。
+
+**代码预览钉住复制条并去掉卡片填充。**关闭折行时，[CodeBody.module.css](../../../../packages/client/ui-sidebar-documentpreview/src/client/code/CodeBody.module.css) 把渲染器设为 `max-content`，让吸附的复制条拥有完整滚动宽度可骑行，并以 `sticky; left: 0; width: 100cqw` 把它钉在文档滚动区上（预览正文设 `container-type: inline-size`）。共享 CodeBlock 的填充改经新变量 `--dsl-code-block-background`（默认值不变，会话保持灰色卡片），共享复制条带上惰性的 `data-code-block-banner` 钩子；预览把变量设为 `transparent`，代码于是坐在分栏自身的背景上。
+
+## Alternatives considered
+
+**保留出生即播种。**折叠列里躺着没人要的页面，且种子占据每个新停靠面的 0 号位，排在第一次真实打开之前。
+
+**保留全停靠面的页去重。**显式"在这里打开"时焦点跳到另一格——正是引发这次改动的抱怨。
+
+**菜单用裸的 window blur 关闭。**每次应用或标签页切换都会关掉列表；`activeElement` 门把关闭收窄到父文档看不见的那一种情形。
+
+**代码横轴用内层滚动。**在 `pre` 上恢复 `overflow-x: auto` 能让复制条不动，但横向滚动条会落在整个代码块底部——长文件里够不着——而且两个轴本就有意放在文档 owner 的滚动区里。
+
+## Consequences
+
+`planDropTab` 的工厂参数是任何嵌入方都可传的新套件 API；`planSettle` 本就接受缺省工厂，如今它同时命名了侧边栏的折叠态行为。`--dsl-code-block-background` 变量与 `data-code-block-banner` 属性是代码块的 owner 定制接缝；共享样式表没有任何规则指向该属性。套件 planner 规格覆盖带回填的本格分栏及其聚焦顺序；侧边栏 store、service 与 seat 规格覆盖惰性播种、格内页合并与折叠后的空布局；一条 Menu 规格覆盖带门的 blur 关闭。`ui-sidebar-right`、`ui-dockkit` 与 `ui-sidebar-documentpreview` 的 README 重述了这些规则。

 - `applyOp(state, op)` returns the next state **and the operations that undo it**. Inverses are captured when an operation runs, because by undo time the pre-operation state is gone.
 - Every operation carries the ids it creates, so `replay(initial, ops)` reproduces the same tree. The engine reads no clock and no random source.
 - `Sequencer` keeps a linear history with one entry per intent: the operations one gesture or command produced step back and forward together, a run of consecutive focus-only entries steps as one, and a new entry after stepping back drops the forward branch.

+- `planSettle` is the opt-in rule that keeps every docked pane populated after an intent: panes an intent emptied are merged away, and an emptied root pane is reseeded through the embedder's factory — withholding the factory keeps the merge and leaves the root pane empty. An embedder that wants empty panes simply does not call it, or calls it without a factory. `planDropTab` takes the same factory: with one, a sole tab released on its own pane's edge splits and the factory's tab backfills the pane it vacates (the dragged tab stays focused); without one that release changes nothing.
 - `DockController` is the intent layer and an observable source (`subscribe` + `getSnapshot`, whose reference only changes when the layout does).
 
 **The components** render a layout snapshot and report settled intents — one per gesture, never a drag frame. A drag previews in local state while the gesture's own facts stay in its closure; on release the net result leaves through one `DockIntents` call — a strip release reports the caret slot as drawn, the dragged chip counted, and `planPlaceTab` turns that into the reorder or the move. That is what lets an embedder record exactly one history entry per gesture. The strip follows the WAI-ARIA tabs pattern with manual activation: the selected chip is in the tab order; Left and Right (wrapping), Home, and End move focus between chips without selecting; Enter or Space selects the focused chip through the same intent as a click. A chip is a capsule carrying one control, its close; the context menu (a secondary press on the chip) carries the same close plus the embedder's items — a menu that would hold no item at all never shows — and renders in a portal positioned against the chip because the chip box clips its overflow on purpose (see below). After the chips sits the add control, which asks the embedder (`DockIntents.addTab`) to seat its seeded tab; the embedder's `canAddTab(paneId)` decides per pane whether the control is drawn at all. Copying a tab has no kit control — it is the embedder's API — and floating is the drag released clear of the surface.

 - `applyOp(state, op)` 返回下一状态**以及撤销它的操作**。逆操作在操作执行时捕获，因为到撤销时操作前的状态已经不存在了。
 - 每个操作都携带它创建的 id，因此 `replay(initial, ops)` 能复现同一棵树。引擎不读时钟，也不读随机源。
 - `Sequencer` 维护一条线性历史，每个意图一条记录：一次手势或命令产生的操作一起后退、一起前进，连续的纯焦点记录作为一步，后退后的新记录会丢弃前进分支。

+- `planSettle` 是可选加入的规则，保证意图之后每个停靠格都有内容：被意图清空的格会被并掉，被清空的根格通过嵌入方的工厂重新播种——不传工厂则只并格、让根格保持为空。想要空格的嵌入方只需不调用它，或不带工厂调用。`planDropTab` 接受同一工厂：带工厂时，唯一 tab 放到本格边缘会分栏，工厂的 tab 回填它腾出的格（被拖的 tab 保持聚焦）；不带工厂时这种释放不改变任何东西。
 - `DockController` 是意图层，也是一个可观察源（`subscribe` + `getSnapshot`，其引用只在布局变化时才变）。
 
 **组件**渲染布局快照并上报已落定的意图——每次手势一条，绝不上报拖动帧。拖动过程中在本地状态里预览，手势自身的事实留在它的闭包里；松手时净结果通过一次 `DockIntents` 调用离开——在标签条上松手上报的是按绘制顺序数出的插入槽位（被拖的 chip 也计入），由 `planPlaceTab` 换算成重排或移动。正是这一点让嵌入方能为每次手势记录恰好一条历史。标签条遵循 WAI-ARIA tabs 模式的手动激活：选中的 chip 在 Tab 键序里；左右方向键（循环）、Home、End 只在 chip 之间移动焦点而不选中；Enter 或空格选中当前聚焦的 chip，走与点击相同的意图。chip 是一个胶囊，携带唯一的控件——它的关闭按钮；上下文菜单（在 chip 上的次键按下）携带同样的关闭项加上嵌入方的条目——一个连一项都没有的菜单绝不展示——并渲染在按 chip 定位的 portal 里，因为 chip 盒会故意裁掉溢出（见下文）。chip 之后是添加控件，它请嵌入方（`DockIntents.addTab`）安放其种子 tab；嵌入方的 `canAddTab(paneId)` 按格决定是否绘制该控件。复制 tab 没有套件控件——那是嵌入方的 API——而浮出就是把拖动松手在停靠区之外。

+After every action the kit's settle planner keeps the expanded surface populated: a docked pane whose last tab was moved out or floated is merged away, and an emptied root pane receives the default page. A collapsed surface holds no such backfill — a session starts collapsed and empty, and a close that collapses the column leaves it empty — the expansion that would first show an empty layout is what seeds the default page. Explicit closing follows [the default-page and close rules](#the-guide). While expanded there is always at least one tab, and never an empty pane — so there is no separate "close pane" gesture.
 
 The docked surface's last tab carries one more rule, decided in the store's `closeTab` and mirrored to the kit through `canCloseTab`: the guide standing as the only docked tab draws no close control and no menu close item — its chip sits quiet, and with no extension item contributed a secondary press opens no menu — and a programmatic close of it records nothing; any other tab standing alone closes together with the column in one entry — the settle planner reseeds the current default page for the next expansion. Floating panels take no part in the rule: they render whether or not the column is expanded, and their tabs close freely.

A resource address is a `dsh-resource://<type>/…` URI; without `options.kind` the registry claims it (globs and `canOpen`, best band wins), with it that kind's type in force opens it. A page is named by kind; the tab is recorded under an address this package composes and nobody else spells (`contract/seed.ts`).

Then the Tab domain records the navigation — `params` reach the body as `navigation.params`, with `revision` stepped — outside the layout history. `params` is typed by what is opened: a viewer for a resource type merges its entry into `SidebarRightResourceParamsMap` (the text preview declares `{ line?: number }`); a page type that takes parameters merges into `SidebarRightTabParamsMap` under its kind; values are JSON-shaped by convention, unchecked at run time.

 `close(tabId)` closes a tab; `active()` reads the active tab. `isExpanded()` and `toggleExpanded()` read and drive the column's expansion; the presentation switch is the panel's own control and not part of this face. Layout operations, for callers that arrange the column programmatically, each recorded like the gesture it stands in for: `focus(tabId)` focuses a tab and its pane; `split(paneId?)` splits a docked pane (the active one by default) under the same pane budget and room rule as the strip's control and returns the new pane's id, or `undefined` — recording nothing — when it cannot; `float(tabId, rect?)` takes a docked tab out into a panel; `dock(paneId)` returns a floating panel to the active docked pane. A tab or pane that does not exist, or already is where the call would put it, is left alone. The face exposes operations only: no layout snapshot, no operation log, no lookup by address. `_undo()` / `_redo()` step the mounted surface's history; they are `@internal` — the sequence has no user-facing control, and these exist for tests. Commands need a mounted session surface; with none, they throw rather than write into a surface nobody draws.

 Default pages depend on the number of registered guide entries, not the number of tab types or open tabs. Exactly one entry opens its page directly (Files in the shipped composition); zero or multiple entries open the guide. Explicitly adding a guide still opens the guide, even with one entry. The sole docked guide is the only tab that cannot close; closing any other sole tab also collapses the column. The chip, context menu, and `close` API apply the same rule.
 
-The guide tab is one entry capsule (a glyph and a title, nothing else) per `guide` entry the registered types contributed, in `order`, centred in the body; the guide has no words of its own. Picking a capsule calls `tab.actions.openTab(entry.kind, { replaceTab: true })`, so the guide gives way to the page it opened. A pane holds at most one guide tab. The strip's add control is drawn only while its pane holds none and opens one there with `openTab('guide', { paneId, revealIfOpened: false })`, so a guide in another pane does not capture the click; opening the guide into a pane that already has one focuses it instead; a guide dragged, dropped, or docked into such a pane merges into it — the arriving guide closes and the pane's own is focused; `duplicateTab` on the guide records nothing. A split or an emptied root pane uses the same default-page rule, one tab per new pane. A plain `openTab('guide')` keeps the tree-wide reveal every open has. The product allows two horizontal panes, initially equal, with divider ratios limited to 20%–80%. Insufficient width blocks a new split; with two panes already present, a body drop moves the tab between panes instead of creating a third.

 `api/remotes` and both root aggregates reference the matching Host/Client leaf. The package exports `.`, `./client`, `./types`, `./typert`, and `./remote`, with one `workspace-files` web-app row supplying both faces. The Client plugin injects `['resources', 'remote', 'remote.workspaceFiles']`; the resource model takes result types directly from the protocol package, and the text preview owns the Sidebar parameter declaration, so the Client compilation graph has no reverse dependency on Remote assembly or Sidebar UI.

The Gateway resolves it from the wire Session identity by reading the live Session header or, for a cold Session, `SessionPersistence.stat`; it never activates an Agent, reads the event body, or falls back to a parent Session.

 `read`, `readBytes`, `readAll`, `readRelated`, and `stat` share regular-file checks and then rely on the filesystem backend's read authority. `list` shares path inspection but also checks workspace containment, while `changes` filters observations to the workspace root. The service applies the following checks:
 
 1. **The path itself.** `lstat` inspects the path before anything follows it: a missing path is `not-found`, and a symlink — wherever it points, including back inside the workspace — is `not-regular-file` (kind `symlink`) for the file methods and `not-directory` for `list`. An empty path is a `gateway/bad-request`.
-2. **Workspace containment for `list`.** The directory resolves to a target and `ctx.fs.contains(root, target)` decides, where `root` is `sandboxPolicy.resolve({ session }).workspaceRoot` resolved the same way. A `..` traversal or an absolute directory outside the root is `outside-workspace`. `changes` applies the same backend containment predicate to observed targets.

 3. **The caps.** A page or window above `maxBytes`, or a `read` asking for more than `maxLines`, is refused, never shortened, because a silently cut page reads as the whole page; a listing above `maxEntries` is cut and says so. Complete and related-file reads are refused above `maxFileBytes`.
 4. **Text.** For `read` only: content that is not UTF-8 up to the end of the page, a NUL byte in the backend's 8 KiB opening sample, or a NUL byte anywhere in the page is `not-text`; bytes past the page are not inspected.

+- Workspace file access belongs to the Host/Client faces of `api/workspace-files`; the Session Controller carries neither implementation, and compiler and runtime entries stay separate. Header-only Session scope lets ordinary, subagent, live, and cold Sessions resolve their own relative paths without an Agent lifecycle or parent fallback.
 - A file of any size opens: text by line page, anything by byte window, each costing one page or window of memory on the Host; complete reads instead enforce `maxFileBytes`; the cost is that a consumer assembles pages itself and that a single line above `maxBytes` has no page at all, because pages are cut by lines.
 - Every filesystem provider now offers a windowed raw read. `fs-e2b` pays for it by transferring the skipped prefix, since its SDK cannot seek; `fs-local` seeks.
 - Paths on the wire are canonical: `absolutePath` and change frames spell a file with symlinks resolved. A follower binds to successful `stat.absolutePath`, so another spelling of the same file — a workspace root reached through a symlink — uses that canonical change key.

 ## Summary
 
-Use this package to preview files readable through a Session's filesystem from the web client. It reads UTF-8 text by page, reads bounded byte windows or complete files, resolves related files from a base file's directory, and reports file metadata. File reads may target paths outside the workspace; directory listing and Agent-write change observation remain workspace-scoped. The service exposes no mutation operation.

 ### Addressing and paths
 
-`read`, `readBytes`, `readAll`, `readRelated`, and `stat` accept an absolute path or one relative to the Session's workspace root. The composed filesystem decides whether the path is readable; the service does not impose workspace containment on file reads. `readRelated` resolves a relative filesystem path from the base file's directory, including when either file is outside the workspace. These methods report the file's absolute path in the filesystem's execution world. `list` remains workspace-scoped and reports the listed directory relative to that root. `changes` likewise reports only Agent observations inside the workspace root.

 ### Design concept
 
-Reads through `ctx.fs` use the backend's read authority; the sandboxing backend fences writes and edits, not reads. The service adds regular-file checks and bounded transfer, while workspace containment belongs only to directory listing and change observation. A page is cut from `streamText`, which decodes and rejects non-UTF-8 chunk by chunk: the cutter counts lines before the window without keeping them, admits each in-window segment against the byte cap before buffering it, and returns at the first character past the window. One `stat` before the stream names the version and size the page reports.
+Reads through `ctx.fs` use the backend's read authority; the sandboxing backend fences writes and edits, not reads.

 Remote calls run Client → Host over the application's shared Connection. API Gateway owns Remote transport, while the controller packages own Session, configuration-surface, and Workspace behavior. Feature packages register exact Connection Fetch routes for responses that do not fit Remote invocation, such as streamed downloads.

 ## Use this package
 
-Mount the package beside `dsh-fs`, `dsh-sandbox-policy`, the Session store, and the Typert Gateway; the bundle does so right after the Session Controller. Every method takes the Session identity on the wire, so a Client calls `remote.workspaceFiles.read(sessionId, path, range, signal)`, `stat(sessionId, path, signal)`, `readBytes(sessionId, path, range, signal)`, `list(sessionId, path, signal)`, or `changes(sessionId, signal)` and never names a root itself. The Host reads a live Session header or uses persistence `stat` for a cold Session; it does not activate an Agent, read the event body, or borrow a parent Session's root.

+# Agent Note: Mermaid previews in Chat code fences
+
+Status: implemented
+
+English | [中文](2026-09-07-web-mermaid-preview.zh.md)
+
+## Problem
+
+Assistant replies can describe diagrams in Mermaid code fences, but readers must interpret the source or copy it to another renderer. Rendering must handle incomplete streaming input and untrusted diagram content while remaining reusable outside Chat.
+
+## Decision
+
+Chat enables settled fence previews through `MarkdownLabels.mermaid`. The shared Markdown renderer uses the parsed fence language; streaming fences and consumers without those labels retain code display. The static [UI primitives package](../../../../packages/client/ui-primitives/README.md) owns `MermaidPreview`, which accepts source and localized labels without Session, file, or Cordis dependencies. `CodeBlock.preview` reuses the banner and copy action; copying always reads the source prop.
+
+Mermaid loads on demand. Its public render API serializes diagram work, and each call removes its temporary measurement DOM in `finally`. Strict security, disabled HTML labels, the neutral theme, and error-rendering policy cannot be overridden by diagram configuration. Generated SVG is displayed as an image without installing diagram links or scripts. Intrinsic dimensions come from the SVG viewBox; large diagrams shrink to fit, and the canvas stays light in both application themes.
+
+Source replacement and unmounting cancel result publication. Cancellation before runtime loading completes prevents rendering; an active Mermaid render finishes and releases its DOM but cannot publish to a cancelled component. Failures show a localized error and the original source. Replacing invalid source with a valid diagram recovers the preview.
+
+## Alternatives considered
+
+**Render each streamed chunk.** Incomplete diagrams are frequently invalid, and repeated layout work competes with text streaming. The existing message-settlement boundary provides a complete source value.
+
+**Put rendering inside Chat or add a general preview registry.** A shared primitive with plain props satisfies reuse without another registry or feature-plugin dependency. This follows the [shared-control rule](../architecture/2026-09-05-shared-client-control-primitives.md).
+
+**Insert interactive SVG into the message.** The requested preview needs diagram display and source access. Displaying the result as an image keeps diagram links and event handlers inactive.
+
+## Consequences
+
+The feature changes presentation without changing persisted messages, provider requests, tools, or Host APIs. Mermaid adds lazily loaded browser assets. Rendering still runs on the browser thread, and work already handed to the library cannot be interrupted. The initial feature has no editing, export, zoom controls, or interactive diagram links.
+
+Component tests cover delayed completion, stale success and failure, unmounting, source fallback, and copying. The keyless [browser scenario](../../../../apps/web/tests/markdown-mermaid.e2e.ts) exercises the assembled Chat with Chinese flowcharts, sequence diagrams, malformed source, configuration overrides, and English/Chinese UI snapshots.

+
+## 问题
+
+Assistant 回复可以在 Mermaid 代码 fence 中描述图表，但读者必须理解源码或把它复制到其他渲染器。渲染需要处理不完整的流式输入与不可信图表内容，同时保持在 Chat 之外的可复用性。

+Chat 通过 `MarkdownLabels.mermaid` 启用已定稿 fence 预览。共享 Markdown 渲染器使用解析后的 fence 语言；流式 fence 和未传入这些 label 的调用方保留代码显示。静态 [UI primitives 包](../../../../packages/client/ui-primitives/README.zh.md)拥有 `MermaidPreview`，它接收源码与本地化 label，不依赖 Session、文件或 Cordis。`CodeBlock.preview` 复用标题栏和复制操作；复制始终读取源码 prop。
+
+Mermaid 按需加载。它的公开 render API 串行执行图表工作，每次调用在 `finally` 中移除临时测量 DOM。图表配置无法覆盖严格安全模式、禁用 HTML label、中性主题和错误渲染策略。生成的 SVG 以图片显示，不安装图内链接或脚本。固有尺寸取自 SVG viewBox；大图缩小以适应宽度，画布在两种应用主题下均保持浅色。
+
+替换源码与卸载组件会取消结果发布。在运行时加载完成前取消可阻止渲染；已经开始的 Mermaid 渲染会完成并释放 DOM，但无法向已取消的组件发布结果。失败时显示本地化错误和原始源码。用有效图表替换非法源码可恢复预览。
+
+## 考虑过的替代方案
+
+**渲染每个流式分片。** 不完整的图表经常无效，反复布局也会与文本流式输出竞争。已有的消息定稿边界提供完整源码值。
+
+**把渲染放在 Chat 内或增加通用预览注册表。** 接收普通 prop 的共享原语无需另一套注册表或功能插件依赖即可满足复用。这遵循[共享控件规则](../architecture/2026-09-05-shared-client-control-primitives.zh.md)。
+
+**把可交互 SVG 插入消息。** 此次预览需求只需要图表显示与源码访问。将结果显示为图片后，图内链接和事件处理器不会生效。
+
+## 后果
+
+功能只改变展示，不改变持久化消息、提供者请求、工具或 Host API。Mermaid 增加按需加载的浏览器资源。渲染仍在浏览器线程上执行，已交给库的工作无法中断。首版不包含编辑、导出、缩放控件或可交互图内链接。
+
+组件测试覆盖延迟完成、过期成功与失败、卸载、源码回退和复制。无密钥[浏览器场景](../../../../apps/web/tests/markdown-mermaid.e2e.ts)通过完整 Chat 组合验证中文流程图、时序图、非法源码、配置覆盖以及英文／中文 UI 快照。

 Each nonempty appended `system/message` owns a collapsed prompt row, including a complete prompt at the start of a headerless window; the same-step header does not duplicate it. Chat also shows a collapsed `System prompt` row for a non-empty initial request, explicit message-series start, or `system/message` surface node replacement whose text differs, reading the last nonempty surviving system node in surface order at the `request/header`; a non-initial request whose preceding header is outside the loaded history window also shows one. A resume repeats the row even when its system text is unchanged, including after pagination supplies the preceding header and system node; same-series config-only or tool-only changes, tool steps, and retries create no repetition, and a `system/message` event is never rendered as a transcript message. 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 request whose system node is empty or outside the loaded window creates no row until the page holding the node arrives.

+## Mermaid previews
+
+Settled Assistant Markdown shows `mermaid` code fences as diagrams. Each fence offers Source/Preview switching and copies the original Mermaid source in either view. Streaming fences remain code until the message settles; invalid diagrams show an error and their source without disrupting other blocks. Chat enables the shared [Mermaid preview primitive](../ui-primitives/README.md) through localized labels. This is a presentation change and adds no model prompt, tool, or Session event.

 `MarkdownText` renders untrusted GFM and TeX math, blocks unsafe links and images, and can turn resolved file mentions into explicit controls. When the owner passes a `pathImages` vocabulary, image destinations that are local media paths rewrite to displayable URLs on settled renders only (the same streaming gate as file mentions); without a vocabulary, local destinations remain inert alt text. A load or decode failure replaces the image with its authored alt text, or the original destination when alt is empty. Changing the image source permits a fresh load. While a reply streams, it freezes completed blocks, advances a top-level open fence by completed lines, and highlights that fence from saved Shiki grammar state. Completed token lines enter fixed-size React groups, so later chunks reconcile only the growing group; an unchanged fence retains that DOM when the final full parse resolves cross-document syntax. `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 `projectUserText` projects sent user text into inline plain runs and reference chips for the message bubble and queue rows.
 
+`MermaidPreview` renders complete Mermaid source on a light canvas. Rendering loads Mermaid on demand, uses strict security, and exposes the generated SVG as an image with no diagram link handlers. A render failure shows the original source with the supplied error label; replacing the source discards late results from the previous render. The diagram keeps its intrinsic size and shrinks to fit the available width.
+
+Supply `MarkdownLabels.mermaid` to enable `mermaid` fence previews in a Markdown consumer; without it, fences remain code. Previews start after the message settles. `CodeBlock.preview` supplies an optional alternate body and localized Source/Preview switch labels while the existing Copy button always copies the source. [The Mermaid decision](../../../.agents/notes/implemented/feature/2026-09-07-web-mermaid-preview.md) records the rendering and reuse choices.

 ## Decision
 
-Chat enables settled fence previews through `MarkdownLabels.mermaid`. The shared Markdown renderer uses the parsed fence language; streaming fences and consumers without those labels retain code display. The static [UI primitives package](../../../../packages/client/ui-primitives/README.md) owns `MermaidPreview`, which accepts source and localized labels without Session, file, or Cordis dependencies. `CodeBlock.preview` reuses the banner and copy action; copying always reads the source prop.

The static [UI primitives package](../../../../packages/client/ui-primitives/README.md) owns `MermaidPreview`, which accepts source and localized labels without Session, file, or Cordis dependencies. `CodeBlock.preview` owns view switching and source copying. Previews omit the language banner and expose compact icon actions on hover or keyboard focus; touch devices keep those actions visible. Source and preview share the same focused toggle button, and copying always reads the source prop.
 
 Mermaid loads on demand. Its public render API serializes diagram work, and each call removes its temporary measurement DOM in `finally`. Strict security, disabled HTML labels, the neutral theme, and error-rendering policy cannot be overridden by diagram configuration. Generated SVG is displayed as an image without installing diagram links or scripts. Intrinsic dimensions come from the SVG viewBox; large diagrams shrink to fit, and the canvas stays light in both application themes.

 ## Alternatives considered
 
+**Keep the code banner above diagrams.** A language label and permanent text controls distract from the diagram. Overlay actions retain source access without reserving a title row.
+
 **Render each streamed chunk.** Incomplete diagrams are frequently invalid, and repeated layout work competes with text streaming. The existing message-settlement boundary provides a complete source value.
 
 **Put rendering inside Chat or add a general preview registry.** A shared primitive with plain props satisfies reuse without another registry or feature-plugin dependency. This follows the [shared-control rule](../architecture/2026-09-05-shared-client-control-primitives.md).

-Chat 通过 `MarkdownLabels.mermaid` 启用已定稿 fence 预览。共享 Markdown 渲染器使用解析后的 fence 语言；流式 fence 和未传入这些 label 的调用方保留代码显示。静态 [UI primitives 包](../../../../packages/client/ui-primitives/README.zh.md)拥有 `MermaidPreview`，它接收源码与本地化 label，不依赖 Session、文件或 Cordis。`CodeBlock.preview` 复用标题栏和复制操作；复制始终读取源码 prop。

 Mermaid 按需加载。它的公开 render API 串行执行图表工作，每次调用在 `finally` 中移除临时测量 DOM。图表配置无法覆盖严格安全模式、禁用 HTML label、中性主题和错误渲染策略。生成的 SVG 以图片显示，不安装图内链接或脚本。固有尺寸取自 SVG viewBox；大图缩小以适应宽度，画布在两种应用主题下均保持浅色。

 ## 考虑过的替代方案
 
+**在图表上方保留代码标题栏。** 语言标记和常驻的文字操作分散了对图表的注意力。浮层操作无需占用标题行即可保留源码入口。
+
 **渲染每个流式分片。** 不完整的图表经常无效，反复布局也会与文本流式输出竞争。已有的消息定稿边界提供完整源码值。
 
 **把渲染放在 Chat 内或增加通用预览注册表。** 接收普通 prop 的共享原语无需另一套注册表或功能插件依赖即可满足复用。这遵循[共享控件规则](../architecture/2026-09-05-shared-client-control-primitives.zh.md)。

 `MermaidPreview` renders complete Mermaid source on a light canvas. Rendering loads Mermaid on demand, uses strict security, and exposes the generated SVG as an image with no diagram link handlers. A render failure shows the original source with the supplied error label; replacing the source discards late results from the previous render. The diagram keeps its intrinsic size and shrinks to fit the available width.

 ## Decision
 
-Chat enables settled fence previews through `MarkdownLabels.mermaid`. The shared Markdown renderer uses the parsed fence language; streaming fences and consumers without those labels retain code display. The static [UI primitives package](../../../../packages/client/ui-primitives/README.md) owns `MermaidPreview`, which accepts source and localized labels without Session, file, or Cordis dependencies. `CodeBlock.preview` owns view switching and source copying. Previews omit the language banner and expose compact icon actions on hover or keyboard focus; touch devices keep those actions visible. Source and preview share the same focused toggle button, and copying always reads the source prop.
+Chat enables settled fence previews through `MarkdownLabels.mermaid`. The shared Markdown renderer uses the parsed fence language; streaming fences and consumers without those labels retain code display. The static [UI primitives package](../../../../packages/client/ui-primitives/README.md) owns `MermaidPreview`, which accepts source and localized labels without Session, file, or Cordis dependencies. `CodeBlock.preview` owns view switching and source copying. Previews omit the language banner and expose compact icon actions on hover or keyboard focus; devices with any touch input keep those actions visible below the diagram. Switching to source hides the mounted preview, so returning preserves completed rendering and pending work. Source and preview share the same focused toggle button, and copying always reads the source prop.
 
 Mermaid loads on demand. Its public render API serializes diagram work, and each call removes its temporary measurement DOM in `finally`. Strict security, disabled HTML labels, the neutral theme, and error-rendering policy cannot be overridden by diagram configuration. Generated SVG is displayed as an image without installing diagram links or scripts. Intrinsic dimensions come from the SVG viewBox; large diagrams shrink to fit, and the canvas stays light in both application themes.

 Mermaid 按需加载。它的公开 render API 串行执行图表工作，每次调用在 `finally` 中移除临时测量 DOM。图表配置无法覆盖严格安全模式、禁用 HTML label、中性主题和错误渲染策略。生成的 SVG 以图片显示，不安装图内链接或脚本。固有尺寸取自 SVG viewBox；大图缩小以适应宽度，画布在两种应用主题下均保持浅色。

 `MermaidPreview` renders complete Mermaid source on a light canvas. Rendering loads Mermaid on demand, uses strict security, and exposes the generated SVG as an image with no diagram link handlers. A render failure shows the original source with the supplied error label; replacing the source discards late results from the previous render. The diagram keeps its intrinsic size and shrinks to fit the available width.

 These limits define how the atoms behave at the edges; they are current package constraints, not a component roadmap.
 
+- **Mermaid rendering runs on the browser thread** — every mounted settled preview starts rendering, including off-screen diagrams. Mermaid serializes layouts; work already submitted to it cannot be interrupted. Preview virtualization and worker rendering are not provided.
 - **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.
 - **A long highlighted fence retains its complete token DOM** — streaming avoids re-parsing, re-tokenizing, and reconciling the completed prefix, but it does not discard old colors or virtualize token spans. Final DOM cardinality therefore still follows the fence's token count; nested/container fences and a pathological single long line remain on the general tail path.
 - **Glyph-level icons are redrawn approximations** — the fish logo and the sparkle mark 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.

+The [static fence preview decision](2026-09-09-markdown-static-previews.md) owns Graphviz, SVG, and HTML sandboxing and shared preview license distribution.
+
 ## Consequences
 
 The feature changes presentation without changing persisted messages, provider requests, tools, or Host APIs. Mermaid adds lazily loaded browser assets. Rendering still runs on the browser thread, and work already handed to the library cannot be interrupted. The initial feature has no editing, export, zoom controls, or interactive diagram links.

+
+## Problem
+
+Readers need to see DOT diagrams, SVG artwork, and HTML examples directly in Assistant replies. These sources are untrusted, and a renderer's npm license field may omit compiled components with separate distribution obligations.
+
+## Decision
+
+The shared Markdown renderer enables settled `graphviz`/`dot`, `svg`, and `html` fences through localized `MarkdownLabels.preview`. `CodeBlock.preview` owns default visualization, source switching, and verbatim copying. `SourcePreview` owns loading, failure, and cancellation of stale result publication for both these documents and the [Mermaid preview](2026-09-07-web-mermaid-preview.md). Consumers without preview labels and streaming messages retain code.
+
+HTML uses DOMPurify with navigation attributes and document-loading elements forbidden, followed by an opaque `sandbox=""` iframe. A trusted CSP precedes source markup and permits only inline CSS, data images, and data fonts. Scripts, external resources, child frames, form submission, and same-origin access are unavailable. SVG is parsed as XML and placed in an image inside the frame, so SVG scripts and links never become active. Frames have a fixed scrollable viewport: measuring their content would require additional origin access or trusted frame scripts. Mermaid keeps its existing strict renderer and inert image presentation.
+
+Graphviz uses the pinned, unmodified `@viz-js/viz` 3.30.0 WebAssembly distribution with the `dot` layout engine. Its npm MIT declaration covers the wrapper; its build provenance identifies Graphviz 16.0.0 (EPL-2.0), Expat 2.8.4 (MIT), and Emscripten 5.0.7 (MIT/NCSA). Distribution retains these component terms and the exact Graphviz source download under EPL-2.0 section 3.1. [Full preview notices](../../../../packages/client/ui-primitives/THIRD_PARTY_PREVIEW_NOTICES.txt) also retain Mermaid's MIT text and select Apache-2.0 for DOMPurify. The UI primitives package ships the notices and the Web build emits the same bytes alongside its assets. License review covers embedded payloads separately from the general permissive npm-metadata policy.
+
+## Alternatives considered
+
+**Execute HTML scripts in a frame.** Static chat examples do not need script execution. An empty sandbox plus sanitization and CSP gives the preview fewer capabilities and avoids introducing a frame messaging protocol.
+
+**Insert rendered markup into Chat.** HTML styles and executable SVG would share the application document. Iframes isolate layout and origin; SVG image mode additionally disables SVG behavior.
+
+**Treat Viz.js as MIT-only or use a remote Graphviz service.** The compiled Graphviz license still applies locally; a remote renderer would send conversation content off-device. The bundled renderer retains source availability and legal notices without network rendering.
+
+## Consequences
+
+No Session event, prompt, or tool changes. Inline HTML styles work, while interactive scripts, external assets, and links do not. Graphviz adds a lazy WebAssembly asset and synchronous browser-thread layout; source cancellation prevents publication but cannot preempt active layout. Mermaid's existing layout limitations remain documented in its owning note.
+
+Component tests cover source copying, default preview, fallback, cancellation, and recovery. The keyless [browser scenario](../../../../apps/web/tests/markdown-mermaid.e2e.ts) verifies opaque frames, real image decoding, source toggling, blocked script/navigation/resource attempts, locale snapshots, and served license text. Notices checks pin the reviewed wrapper and native provenance so upgrades require renewed review.

+# Agent Note: 静态 Markdown fence 预览
+
+Status: implemented

+[English](2026-09-09-markdown-static-previews.md) | 中文
+
+## Problem
+
+读者需要直接在 Assistant 回复中查看 DOT 图表、SVG 图像和 HTML 示例。这些源码不可信，而渲染器的 npm 许可证字段可能遗漏编译组件各自的分发义务。
+
+## Decision
+
+共享 Markdown 渲染器通过本地化的 `MarkdownLabels.preview` 启用定稿后的 `graphviz`/`dot`、`svg` 和 `html` fence。`CodeBlock.preview` 负责默认可视化、源码切换与原样复制。`SourcePreview` 为这些文档及 [Mermaid 预览](2026-09-07-web-mermaid-preview.zh.md)负责加载、失败和取消过期结果发布。未提供预览文案的调用方与流式消息保留代码显示。
+
+HTML 先由 DOMPurify 清理，禁止导航属性与文档加载元素，再进入不透明来源的 `sandbox=""` iframe。可信 CSP 位于源码标记之前，仅允许内联 CSS、data 图片与 data 字体。脚本、外部资源、子 iframe、表单提交与同源访问均不可用。SVG 按 XML 解析后作为图片放进 iframe，因此 SVG 脚本与链接不会激活。iframe 使用固定的可滚动视口：测量内容需要额外的来源访问权限或可信 iframe 脚本。Mermaid 保留既有的严格渲染器与不可执行图片展示。
+
+Graphviz 使用固定且未修改的 `@viz-js/viz` 3.30.0 WebAssembly 发布包，布局引擎为 `dot`。其 npm MIT 声明覆盖包装层；构建来源记录标明 Graphviz 16.0.0（EPL-2.0）、Expat 2.8.4（MIT）与 Emscripten 5.0.7（MIT/NCSA）。分发保留各组件条款，并按 EPL-2.0 第 3.1 节提供准确的 Graphviz 源码下载地址。[完整预览声明](../../../../packages/client/ui-primitives/THIRD_PARTY_PREVIEW_NOTICES.txt)还保留 Mermaid 的 MIT 文本，并为 DOMPurify 选择 Apache-2.0。UI primitives 包携带该声明，Web 构建在资源旁输出相同字节。内嵌产物的许可证检查独立于通用的宽松 npm 元数据策略。
+
+## Alternatives considered
+
+**在 iframe 内执行 HTML 脚本。** 静态聊天示例不需要脚本执行。空 sandbox、清理与 CSP 降低预览权限，也避免引入 iframe 消息协议。
+
+**把渲染标记插入 Chat。** HTML 样式和可执行 SVG 会与应用共享文档。iframe 隔离布局与来源，SVG 图片模式额外禁用 SVG 行为。
+
+**将 Viz.js 视为仅使用 MIT，或使用远程 Graphviz 服务。** 本地编译的 Graphviz 仍受其许可证约束；远程渲染会把对话内容发送到设备之外。内置渲染器保留源码可获取性与法律声明，无需网络渲染。
+
+## Consequences
+
+不改变 Session 事件、提示词或工具。HTML 内联样式可用，交互脚本、外部资源和链接不可用。Graphviz 增加按需加载的 WebAssembly 资源与浏览器线程同步布局；源码取消可以阻止结果发布，但无法抢占进行中的布局。Mermaid 既有布局限制仍记录在其所属决策中。
+
+组件测试覆盖源码复制、默认预览、回退、取消与恢复。无密钥[浏览器场景](../../../../apps/web/tests/markdown-mermaid.e2e.ts)验证不透明来源 iframe、真实图片解码、源码切换、脚本／导航／资源请求被阻止、本地化快照和已提供的许可证文本。声明检查固定已审查的包装层与原生构建来源，升级时须重新审查。

+The Markdown preview distribution also contains Graphviz 16.0.0 (EPL-2.0), Expat 2.8.4 (MIT), and Emscripten 5.0.7 runtime code (MIT/NCSA) inside `@viz-js/viz` 3.30.0.

HTML scripts, navigation, and remote resources are disabled. This is a presentation change and adds no model prompt, tool, or Session event.

 Supply `MarkdownLabels.mermaid` to enable `mermaid` fence previews in a Markdown consumer; without it, fences remain code. Previews start after the message settles. `CodeBlock.preview` supplies an optional headerless body with icon actions for source switching and copying. Actions appear on hover or keyboard focus, and stay visible below the diagram whenever a touchscreen is available, including with a mouse attached. Switching to source keeps the preview mounted, so returning reuses its result; copying always retains the source.

+Supply `MarkdownLabels.preview` to enable `graphviz`/`dot`, `svg`, and `html` fences. Each settled fence defaults to visualization and shares the source/copy controls. Graphviz loads `@viz-js/viz` on demand and renders DOT with the `dot` engine. SVG and Graphviz output are inert images inside opaque sandbox iframes; malformed SVG and DOT retain their source with an error. HTML accepts complete documents or fragments and preserves inline styles, but strips scripts and navigation. Frames have no sandbox permissions, and their Content Security Policy blocks external resources, embedded frames, forms, and scripts. Frames use a 400px scrollable viewport. Raw HTML outside a code fence remains ordinary Markdown input.

 ### Localizing copy
 
 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`, `ConnectionIndicator`, `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.

 - **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.
 - **A long highlighted fence retains its complete token DOM** — streaming avoids re-parsing, re-tokenizing, and reconciling the completed prefix, but it does not discard old colors or virtualize token spans. Final DOM cardinality therefore still follows the fence's token count; nested/container fences and a pathological single long line remain on the general tail path.
 - **Glyph-level icons are redrawn approximations** — the fish logo and the sparkle mark 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.

+    THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS ECLIPSE
+    PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION
+    OF THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
+
+1. DEFINITIONS
+
+"Contribution" means:
+
+  a) in the case of the initial Contributor, the initial content
+     Distributed under this Agreement, and
+
+  b) in the case of each subsequent Contributor:
+     i) changes to the Program, and
+     ii) additions to the Program;
+  where such changes and/or additions to the Program originate from
+  and are Distributed by that particular Contributor. A Contribution
+  "originates" from a Contributor if it was added to the Program by
+  such Contributor itself or anyone acting on such Contributor's behalf.
+  Contributions do not include changes or additions to the Program that
+  are not Modified Works.
+
+"Contributor" means any person or entity that Distributes the Program.
+
+"Licensed Patents" mean patent claims licensable by a Contributor which
+are necessarily infringed by the use or sale of its Contribution alone
+or when combined with the Program.
+
+"Program" means the Contributions Distributed in accordance with this
+Agreement.
+
+"Recipient" means anyone who receives the Program under this Agreement
+or any Secondary License (as applicable), including Contributors.
+
+"Derivative Works" shall mean any work, whether in Source Code or other
+form, that is based on (or derived from) the Program and for which the
+editorial revisions, annotations, elaborations, or other modifications
+represent, as a whole, an original work of authorship.
+
+"Modified Works" shall mean any work in Source Code or other form that
+results from an addition to, deletion from, or modification of the
+contents of the Program, including, for purposes of clarity any new file
+in Source Code form that contains any contents of the Program. Modified
+Works shall not include works that contain only declarations,
+interfaces, types, classes, structures, or files of the Program solely
+in each case in order to link to, bind by name, or subclass the Program
+or Modified Works thereof.
+
+"Distribute" means the acts of a) distributing or b) making available
+in any manner that enables the transfer of a copy.
+
+"Source Code" means the form of a Program preferred for making
+modifications, including but not limited to software source code,
+documentation source, and configuration files.
+
+"Secondary License" means either the GNU General Public License,
+Version 2.0, or any later versions of that license, including any
+exceptions or additional permissions as identified by the initial
+Contributor.
+
+2. GRANT OF RIGHTS
+
+  a) Subject to the terms of this Agreement, each Contributor hereby
+  grants Recipient a non-exclusive, worldwide, royalty-free copyright
+  license to reproduce, prepare Derivative Works of, publicly display,
+  publicly perform, Distribute and sublicense the Contribution of such
+  Contributor, if any, and such Derivative Works.
+
+  b) Subject to the terms of this Agreement, each Contributor hereby
+  grants Recipient a non-exclusive, worldwide, royalty-free patent
+  license under Licensed Patents to make, use, sell, offer to sell,
+  import and otherwise transfer the Contribution of such Contributor,
+  if any, in Source Code or other form. This patent license shall
+  apply to the combination of the Contribution and the Program if, at
+  the time the Contribution is added by the Contributor, such addition
+  of the Contribution causes such combination to be covered by the
+  Licensed Patents. The patent license shall not apply to any other
+  combinations which include the Contribution. No hardware per se is
+  licensed hereunder.
+
+  c) Recipient understands that although each Contributor grants the
+  licenses to its Contributions set forth herein, no assurances are
+  provided by any Contributor that the Program does not infringe the
+  patent or other intellectual property rights of any other entity.
+  Each Contributor disclaims any liability to Recipient for claims
+  brought by any other entity based on infringement of intellectual
+  property rights or otherwise. As a condition to exercising the
+  rights and licenses granted hereunder, each Recipient hereby
+  assumes sole responsibility to secure any other intellectual
+  property rights needed, if any. For example, if a third party
+  patent license is required to allow Recipient to Distribute the
+  Program, it is Recipient's responsibility to acquire that license
+  before distributing the Program.
+
+  d) Each Contributor represents that to its knowledge it has
+  sufficient copyright rights in its Contribution, if any, to grant
+  the copyright license set forth in this Agreement.
+
+  e) Notwithstanding the terms of any Secondary License, no
+  Contributor makes additional grants to any Recipient (other than
+  those set forth in this Agreement) as a result of such Recipient's
+  receipt of the Program under the terms of a Secondary License
+  (if permitted under the terms of Section 3).
+
+3. REQUIREMENTS
+
+3.1 If a Contributor Distributes the Program in any form, then:
+
+  a) the Program must also be made available as Source Code, in
+  accordance with section 3.2, and the Contributor must accompany
+  the Program with a statement that the Source Code for the Program
+  is available under this Agreement, and informs Recipients how to
+  obtain it in a reasonable manner on or through a medium customarily
+  used for software exchange; and
+
+  b) the Contributor may Distribute the Program under a license
+  different than this Agreement, provided that such license:
+     i) effectively disclaims on behalf of all other Contributors all
+     warranties and conditions, express and implied, including
+     warranties or conditions of title and non-infringement, and
+     implied warranties or conditions of merchantability and fitness
+     for a particular purpose;
+
+     ii) effectively excludes on behalf of all other Contributors all
+     liability for damages, including direct, indirect, special,
+     incidental and consequential damages, such as lost profits;
+
+     iii) does not attempt to limit or alter the recipients' rights
+     in the Source Code under section 3.2; and
+
+     iv) requires any subsequent distribution of the Program by any
+     party to be under a license that satisfies the requirements
+     of this section 3.
+
+3.2 When the Program is Distributed as Source Code:
+
+  a) it must be made available under this Agreement, or if the
+  Program (i) is combined with other material in a separate file or
+  files made available under a Secondary License, and (ii) the initial
+  Contributor attached to the Source Code the notice described in
+  Exhibit A of this Agreement, then the Program may be made available
+  under the terms of such Secondary Licenses, and
+
+  b) a copy of this Agreement must be included with each copy of
+  the Program.
+
+3.3 Contributors may not remove or alter any copyright, patent,
+trademark, attribution notices, disclaimers of warranty, or limitations
+of liability ("notices") contained within the Program from any copy of
+the Program which they Distribute, provided that Contributors may add
+their own appropriate notices.
+
+4. COMMERCIAL DISTRIBUTION
+
+Commercial distributors of software may accept certain responsibilities
+with respect to end users, business partners and the like. While this
+license is intended to facilitate the commercial use of the Program,
+the Contributor who includes the Program in a commercial product
+offering should do so in a manner which does not create potential
+liability for other Contributors. Therefore, if a Contributor includes
+the Program in a commercial product offering, such Contributor
+("Commercial Contributor") hereby agrees to defend and indemnify every
+other Contributor ("Indemnified Contributor") against any losses,
+damages and costs (collectively "Losses") arising from claims, lawsuits
+and other legal actions brought by a third party against the Indemnified
+Contributor to the extent caused by the acts or omissions of such
+Commercial Contributor in connection with its distribution of the Program
+in a commercial product offering. The obligations in this section do not
+apply to any claims or Losses relating to any actual or alleged
+intellectual property infringement. In order to qualify, an Indemnified
+Contributor must: a) promptly notify the Commercial Contributor in
+writing of such claim, and b) allow the Commercial Contributor to control,
+and cooperate with the Commercial Contributor in, the defense and any
+related settlement negotiations. The Indemnified Contributor may
+participate in any such claim at its own expense.
+
+For example, a Contributor might include the Program in a commercial
+product offering, Product X. That Contributor is then a Commercial
+Contributor. If that Commercial Contributor then makes performance
+claims, or offers warranties related to Product X, those performance
+claims and warranties are such Commercial Contributor's responsibility
+alone. Under this section, the Commercial Contributor would have to
+defend claims against the other Contributors related to those performance
+claims and warranties, and if a court requires any other Contributor to
+pay any damages as a result, the Commercial Contributor must pay
+those damages.
+
+5. NO WARRANTY
+
+EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, AND TO THE EXTENT
+PERMITTED BY APPLICABLE LAW, THE PROGRAM IS PROVIDED ON AN "AS IS"
+BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR
+IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR CONDITIONS OF
+TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR
+PURPOSE. Each Recipient is solely responsible for determining the
+appropriateness of using and distributing the Program and assumes all
+risks associated with its exercise of rights under this Agreement,
+including but not limited to the risks and costs of program errors,
+compliance with applicable laws, damage to or loss of data, programs
+or equipment, and unavailability or interruption of operations.
+
+6. DISCLAIMER OF LIABILITY
+
+EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, AND TO THE EXTENT
+PERMITTED BY APPLICABLE LAW, NEITHER RECIPIENT NOR ANY CONTRIBUTORS
+SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL,
+EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST
+PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN
+CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE)
+ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE
+EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+7. GENERAL
+
+If any provision of this Agreement is invalid or unenforceable under
+applicable law, it shall not affect the validity or enforceability of
+the remainder of the terms of this Agreement, and without further
+action by the parties hereto, such provision shall be reformed to the
+minimum extent necessary to make such provision valid and enforceable.
+
+If Recipient institutes patent litigation against any entity
+(including a cross-claim or counterclaim in a lawsuit) alleging that the
+Program itself (excluding combinations of the Program with other software
+or hardware) infringes such Recipient's patent(s), then such Recipient's
+rights granted under Section 2(b) shall terminate as of the date such
+litigation is filed.
+
+All Recipient's rights under this Agreement shall terminate if it
+fails to comply with any of the material terms or conditions of this
+Agreement and does not cure such failure in a reasonable period of
+time after becoming aware of such noncompliance. If all Recipient's
+rights under this Agreement terminate, Recipient agrees to cease use
+and distribution of the Program as soon as reasonably practicable.
+However, Recipient's obligations under this Agreement and any licenses
+granted by Recipient relating to the Program shall continue and survive.
+
+Everyone is permitted to copy and distribute copies of this Agreement,
+but in order to avoid inconsistency the Agreement is copyrighted and
+may only be modified in the following manner. The Agreement Steward
+reserves the right to publish new versions (including revisions) of
+this Agreement from time to time. No one other than the Agreement
+Steward has the right to modify this Agreement. The Eclipse Foundation
+is the initial Agreement Steward. The Eclipse Foundation may assign the
+responsibility to serve as the Agreement Steward to a suitable separate
+entity. Each new version of the Agreement will be given a distinguishing
+version number. The Program (including Contributions) may always be
+Distributed subject to the version of the Agreement under which it was
+received. In addition, after a new version of the Agreement is published,
+Contributor may elect to Distribute the Program (including its
+Contributions) under the new version.
+
+Except as expressly stated in Sections 2(a) and 2(b) above, Recipient
+receives no rights or licenses to the intellectual property of any
+Contributor under this Agreement, whether expressly, by implication,
+estoppel or otherwise. All rights in the Program not expressly granted
+under this Agreement are reserved. Nothing in this Agreement is intended
+to be enforceable by any entity that is not a Contributor or Recipient.
+No third-party beneficiary rights are created under this Agreement.

+===== Emscripten =====
+
+Emscripten is available under 2 licenses, the MIT license and the
+University of Illinois/NCSA Open Source License.
+
+Both are permissive open source licenses, with little if any
+practical difference between them.
+
+The reason for offering both is that (1) the MIT license is
+well-known, while (2) the University of Illinois/NCSA Open Source
+License allows Emscripten's code to be integrated upstream into
+LLVM, which uses that license, should the opportunity arise.
+
+The full text of both licenses follows.

+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"

-# Agent Note: Mermaid previews in Chat code fences
-
-Status: implemented
-
-English | [中文](2026-09-07-web-mermaid-preview.zh.md)
-
-## Problem
-
-Assistant replies can describe diagrams in Mermaid code fences, but readers must interpret the source or copy it to another renderer. Rendering must handle incomplete streaming input and untrusted diagram content while remaining reusable outside Chat.
-
-## Decision
-
-Chat enables settled fence previews through `MarkdownLabels.mermaid`. The shared Markdown renderer uses the parsed fence language; streaming fences and consumers without those labels retain code display. The static [UI primitives package](../../../../packages/client/ui-primitives/README.md) owns `MermaidPreview`, which accepts source and localized labels without Session, file, or Cordis dependencies. `CodeBlock.preview` owns view switching and source copying. Previews omit the language banner and expose compact icon actions on hover or keyboard focus; devices with any touch input keep those actions visible below the diagram. Switching to source hides the mounted preview, so returning preserves completed rendering and pending work. Source and preview share the same focused toggle button, and copying always reads the source prop.
-
-Mermaid loads on demand. Its public render API serializes diagram work, and each call removes its temporary measurement DOM in `finally`. Strict security, disabled HTML labels, the neutral theme, and error-rendering policy cannot be overridden by diagram configuration. Generated SVG is displayed as an image without installing diagram links or scripts. Intrinsic dimensions come from the SVG viewBox; large diagrams shrink to fit, and the canvas stays light in both application themes.
-
-Source replacement and unmounting cancel result publication. Cancellation before runtime loading completes prevents rendering; an active Mermaid render finishes and releases its DOM but cannot publish to a cancelled component. Failures show a localized error and the original source. Replacing invalid source with a valid diagram recovers the preview.
-
-## Alternatives considered
-
-**Keep the code banner above diagrams.** A language label and permanent text controls distract from the diagram. Overlay actions retain source access without reserving a title row.
-
-**Render each streamed chunk.** Incomplete diagrams are frequently invalid, and repeated layout work competes with text streaming. The existing message-settlement boundary provides a complete source value.
-
-**Put rendering inside Chat or add a general preview registry.** A shared primitive with plain props satisfies reuse without another registry or feature-plugin dependency. This follows the [shared-control rule](../architecture/2026-09-05-shared-client-control-primitives.md).
-
-**Insert interactive SVG into the message.** The requested preview needs diagram display and source access. Displaying the result as an image keeps diagram links and event handlers inactive.
-
-The [static fence preview decision](2026-09-09-markdown-static-previews.md) owns Graphviz, SVG, and HTML sandboxing and shared preview license distribution.
-
-## Consequences
-
-The feature changes presentation without changing persisted messages, provider requests, tools, or Host APIs. Mermaid adds lazily loaded browser assets. Rendering still runs on the browser thread, and work already handed to the library cannot be interrupted. The initial feature has no editing, export, zoom controls, or interactive diagram links.
-
-Component tests cover delayed completion, stale success and failure, unmounting, source fallback, and copying. The keyless [browser scenario](../../../../apps/web/tests/markdown-mermaid.e2e.ts) exercises the assembled Chat with Chinese flowcharts, sequence diagrams, malformed source, configuration overrides, and English/Chinese UI snapshots.

-# Agent Note: Chat 代码 fence 中的 Mermaid 预览
-
-Status: implemented
-
-[English](2026-09-07-web-mermaid-preview.md) | 中文
-
-## 问题
-
-Assistant 回复可以在 Mermaid 代码 fence 中描述图表，但读者必须理解源码或把它复制到其他渲染器。渲染需要处理不完整的流式输入与不可信图表内容，同时保持在 Chat 之外的可复用性。
-
-## 决策
-
-Chat 通过 `MarkdownLabels.mermaid` 启用已定稿 fence 预览。共享 Markdown 渲染器使用解析后的 fence 语言；流式 fence 和未传入这些 label 的调用方保留代码显示。静态 [UI primitives 包](../../../../packages/client/ui-primitives/README.zh.md)拥有 `MermaidPreview`，它接收源码与本地化 label，不依赖 Session、文件或 Cordis。`CodeBlock.preview` 拥有视图切换与源码复制。预览省略语言标题栏，悬停或键盘聚焦时显示紧凑的图标操作；具备任何触控输入的设备均在图表下方保持操作可见。切换到源码时隐藏已挂载的预览，因此返回时保留已完成的渲染与进行中的工作。源码与预览使用同一个已聚焦的切换按钮，复制始终读取源码 prop。
-
-Mermaid 按需加载。它的公开 render API 串行执行图表工作，每次调用在 `finally` 中移除临时测量 DOM。图表配置无法覆盖严格安全模式、禁用 HTML label、中性主题和错误渲染策略。生成的 SVG 以图片显示，不安装图内链接或脚本。固有尺寸取自 SVG viewBox；大图缩小以适应宽度，画布在两种应用主题下均保持浅色。
-
-替换源码与卸载组件会取消结果发布。在运行时加载完成前取消可阻止渲染；已经开始的 Mermaid 渲染会完成并释放 DOM，但无法向已取消的组件发布结果。失败时显示本地化错误和原始源码。用有效图表替换非法源码可恢复预览。
-
-## 考虑过的替代方案
-
-**在图表上方保留代码标题栏。** 语言标记和常驻的文字操作分散了对图表的注意力。浮层操作无需占用标题行即可保留源码入口。
-
-**渲染每个流式分片。** 不完整的图表经常无效，反复布局也会与文本流式输出竞争。已有的消息定稿边界提供完整源码值。
-
-**把渲染放在 Chat 内或增加通用预览注册表。** 接收普通 prop 的共享原语无需另一套注册表或功能插件依赖即可满足复用。这遵循[共享控件规则](../architecture/2026-09-05-shared-client-control-primitives.zh.md)。
-
-**把可交互 SVG 插入消息。** 此次预览需求只需要图表显示与源码访问。将结果显示为图片后，图内链接和事件处理器不会生效。
-
-[静态 fence 预览决策](2026-09-09-markdown-static-previews.zh.md)负责 Graphviz、SVG、HTML 的 sandbox 及共享预览许可证分发。
-
-## 后果
-
-功能只改变展示，不改变持久化消息、提供者请求、工具或 Host API。Mermaid 增加按需加载的浏览器资源。渲染仍在浏览器线程上执行，已交给库的工作无法中断。首版不包含编辑、导出、缩放控件或可交互图内链接。
-
-组件测试覆盖延迟完成、过期成功与失败、卸载、源码回退和复制。无密钥[浏览器场景](../../../../apps/web/tests/markdown-mermaid.e2e.ts)通过完整 Chat 组合验证中文流程图、时序图、非法源码、配置覆盖以及英文／中文 UI 快照。

+Readers need to see Mermaid and DOT diagrams, SVG artwork, and HTML examples directly in Assistant replies without interpreting source or copying it to another renderer. These sources are untrusted, and a renderer's npm license field may omit compiled components with separate distribution obligations.
 
 ## Decision
 
-The shared Markdown renderer enables settled `graphviz`/`dot`, `svg`, and `html` fences through localized `MarkdownLabels.preview`. `CodeBlock.preview` owns default visualization, source switching, and verbatim copying. `SourcePreview` owns loading, failure, and cancellation of stale result publication for both these documents and the [Mermaid preview](2026-09-07-web-mermaid-preview.md). Consumers without preview labels and streaming messages retain code.

Mermaid and Graphviz each supply a `.ts` renderer to that same component. Consumers without preview labels and streaming messages retain code.
 
-HTML uses DOMPurify with navigation attributes and document-loading elements forbidden, followed by an opaque `sandbox=""` iframe. A trusted CSP precedes source markup and permits only inline CSS, data images, and data fonts. Scripts, external resources, child frames, form submission, and same-origin access are unavailable. SVG is parsed as XML and placed in an image inside the frame, so SVG scripts and links never become active. Frames have a fixed scrollable viewport: measuring their content would require additional origin access or trusted frame scripts. Mermaid keeps its existing strict renderer and inert image presentation.

 Graphviz uses the pinned, unmodified `@viz-js/viz` 3.30.0 WebAssembly distribution with the `dot` layout engine. Its npm MIT declaration covers the wrapper; its build provenance identifies Graphviz 16.0.0 (EPL-2.0), Expat 2.8.4 (MIT), and Emscripten 5.0.7 (MIT/NCSA). Distribution retains these component terms and the exact Graphviz source download under EPL-2.0 section 3.1. [Full preview notices](../../../../packages/client/ui-primitives/THIRD_PARTY_PREVIEW_NOTICES.txt) also retain Mermaid's MIT text and select Apache-2.0 for DOMPurify. The UI primitives package ships the notices and the Web build emits the same bytes alongside its assets. License review covers embedded payloads separately from the general permissive npm-metadata policy.

+**Keep the code banner above diagrams.** A language label and permanent text controls distract from the diagram. Overlay actions retain source access without reserving a title row.

+
 **Execute HTML scripts in a frame.** Static chat examples do not need script execution. An empty sandbox plus sanitization and CSP gives the preview fewer capabilities and avoids introducing a frame messaging protocol.
 
-**Insert rendered markup into Chat.** HTML styles and executable SVG would share the application document. Iframes isolate layout and origin; SVG image mode additionally disables SVG behavior.

 **Treat Viz.js as MIT-only or use a remote Graphviz service.** The compiled Graphviz license still applies locally; a remote renderer would send conversation content off-device. The bundled renderer retains source availability and legal notices without network rendering.
 
 ## Consequences
 
-No Session event, prompt, or tool changes. Inline HTML styles work, while interactive scripts, external assets, and links do not. Graphviz adds a lazy WebAssembly asset and synchronous browser-thread layout; source cancellation prevents publication but cannot preempt active layout. Mermaid's existing layout limitations remain documented in its owning note.

 `MarkdownText` renders untrusted GFM and TeX math, blocks unsafe links and images, and can turn resolved file mentions into explicit controls. When the owner passes a `pathImages` vocabulary, image destinations that are local media paths rewrite to displayable URLs on settled renders only (the same streaming gate as file mentions); without a vocabulary, local destinations remain inert alt text. A load or decode failure replaces the image with its authored alt text, or the original destination when alt is empty. Changing the image source permits a fresh load. While a reply streams, it freezes completed blocks, advances a top-level open fence by completed lines, and highlights that fence from saved Shiki grammar state. Completed token lines enter fixed-size React groups, so later chunks reconcile only the growing group; an unchanged fence retains that DOM when the final full parse resolves cross-document syntax. `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 `projectUserText` projects sent user text into inline plain runs and reference chips for the message bubble and queue rows.

+Mermaid loads on demand. A shared queue serializes theme initialization with diagram work, and each call removes its temporary measurement DOM in `finally`. Strict security, disabled HTML labels, the application palette, and error-rendering policy cannot be overridden by diagram configuration. Generated SVG is displayed as an image without installing links or scripts. Intrinsic dimensions come from the SVG viewBox; large diagrams shrink to fit, and the canvas follows the code-block background. Mounted previews observe document theme attributes and regenerate only when resolved colors change; obsolete renders cannot publish. Graphviz default colors follow the same palette, while authored DOT, SVG, and HTML colors remain intact.
 
 HTML uses DOMPurify with navigation attributes and document-loading elements forbidden, followed by an opaque `sandbox=""` iframe. A trusted CSP precedes source markup and permits only inline CSS, data images, and data fonts. Scripts, external resources, child frames, form submission, and same-origin access are unavailable. SVG is parsed as XML and placed in an image inside the frame, so SVG scripts and links never become active. Frames have a fixed scrollable viewport: measuring their content would require additional origin access or trusted frame scripts.

 `MarkdownText` renders untrusted GFM and TeX math, blocks unsafe links and images, and can turn resolved file mentions into explicit controls. When the owner passes a `pathImages` vocabulary, image destinations that are local media paths rewrite to displayable URLs on settled renders only (the same streaming gate as file mentions); without a vocabulary, local destinations remain inert alt text. A load or decode failure replaces the image with its authored alt text, or the original destination when alt is empty. Changing the image source permits a fresh load. While a reply streams, it freezes completed blocks, advances a top-level open fence by completed lines, and highlights that fence from saved Shiki grammar state. Completed token lines enter fixed-size React groups, so later chunks reconcile only the growing group; an unchanged fence retains that DOM when the final full parse resolves cross-document syntax. `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 `projectUserText` projects sent user text into inline plain runs and reference chips for the message bubble and queue rows.
 
-Supply `MarkdownLabels.preview` to enable settled `mermaid`, `graphviz`/`dot`, `svg`, and `html` fences. Each language supplies localized preview states, and consumers without these labels retain code. Mermaid renders complete source on a light canvas. Rendering loads Mermaid on demand, uses strict security, and exposes the generated SVG as an image with no diagram link handlers. A render failure shows the original source with the supplied error label; replacing the source discards late results from the previous render. The diagram keeps its intrinsic size and shrinks to fit the available width.
+Supply `MarkdownLabels.preview` to enable settled `mermaid`, `graphviz`/`dot`, `svg`, and `html` fences. Each language supplies localized preview states, and consumers without these labels retain code. Mermaid and Graphviz use the active document palette on the code-block background and update mounted previews when the theme changes. Explicit colors in DOT, SVG, and HTML remain authored content. Rendering loads Mermaid on demand, uses strict security, and exposes the generated SVG as an image with no diagram link handlers. A render failure shows the original source with the supplied error label; replacing the source discards late results from the previous render. The diagram keeps its intrinsic size and shrinks to fit the available width.
 
 `CodeBlock.preview` supplies an optional headerless body with icon actions for source switching and copying. Actions appear on hover or keyboard focus, and stay visible below the diagram whenever a touchscreen is available, including with a mouse attached. Switching to source keeps the preview mounted, so returning reuses its result; copying always retains the source.
 
 Each settled fence defaults to visualization and shares the source/copy controls. Graphviz loads `@viz-js/viz` on demand and renders DOT with the `dot` engine. SVG and Graphviz output are inert images inside opaque sandbox iframes; malformed SVG and DOT retain their source with an error. HTML accepts complete documents or fragments and preserves inline styles, but strips scripts and navigation. Frames have no sandbox permissions, and their Content Security Policy blocks external resources, embedded frames, forms, and scripts. Frames use a 400px scrollable viewport. Raw HTML outside a code fence remains ordinary Markdown input.
 
+Internal render functions accept optional native `MermaidConfig` and Viz.js `RenderOptions` for developer customization. Attribute and theme-variable overrides merge with document defaults; Mermaid preview restrictions and Graphviz SVG output remain fixed. These parameters have no settings UI.
+
 [Preview license notices](THIRD_PARTY_PREVIEW_NOTICES.txt) ship with this package and the Web frontend. Mermaid is MIT; Viz.js is MIT but embeds Graphviz under EPL-2.0. The notices retain license texts and the exact Graphviz source download. Dependency upgrades require reviewing the embedded payload as well as npm metadata; the [preview decision](../../../.agents/notes/implemented/feature/2026-09-09-markdown-static-previews.md) records the distribution and sandbox choices.

 ## Decision
 
-`ui-primitives` owns one Cordis-free file classification and rendering API. `fileExtension(path)` applies the shared basename and final-dot semantics to either path separator. `classifyFileType(path)` matches without case sensitivity and returns the closed `FileType` union: the traditional `code`, `excel`, `folder`, `html`, `image`, `markdown`, `other`, `pdf`, `ppt`, `video`, and `word` categories plus the detailed `CodeFileType` set imported from the supplied `square-code-icons` map. Exact filenames, filename prefixes, filename suffixes, optional project context, and extensions run in that order. The path classifier returns every member except `folder`; callers use the explicit `FileTypeIcon` `type` override when they know an entry is a directory. Unknown extensions, missing extensions, and trailing dots resolve to `other`, except the shared table recognizes named files such as `Dockerfile`, `Makefile`, `package.json`, `.gitignore`, `README`, and `CHANGELOG`.

-`FileTypeIcon` accepts a path, shared `IconProps`, the optional explicit type, and an optional project-file snapshot. Traditional file types render the supplied 28px document and folder contours as inline SVG. Excel, Markdown, PDF, PPT, and Word foreground marks scale to 122% around their visual center; the remaining marked traditional glyphs use 112%, while the file body and folded corner retain their source geometry and the generic file has no invented center mark. The sheet is a solid category color, the foreground mark and ordinary folded corner are white, and the generic file has a darker grey corner. CSS assigns the supplied category palette through static design tokens: DeepSeek blue for code/HTML/Markdown, the lighter DeepSeek blue for Word, green for Excel, two amber steps for folder/PPT, red for PDF, and neutral grey for unknown files. Image and video share the supplied violet through a component-local variable because the design platform has no matching violet token. A caller may override a traditional sheet through `--dsh-file-type-icon-color`.

 Recognized code and configuration files render the corresponding 20px square artwork scaled to the requested icon size. These technology marks retain their embedded multicolor fills and are the explicit exception to the ordinary current-color icon rule. The map selects React before TypeScript/JavaScript, Angular filename suffixes before their base extension, Docker/Node/Git/Make/CMake by filename rules, and Flutter only when the optional project snapshot contains a `pubspec.yaml` whose text includes `flutter:`. Markdown and SVG remain owned by the traditional Markdown and image categories. Every traditional and technology SVG is `aria-hidden`, and the card, row, or button that owns the file identity supplies the accessible name.

 ## 决策
 
-`ui-primitives` 统一拥有一套 Cordis-free 的文件分类与渲染 API。`fileExtension(path)` 对两种路径分隔符采用共享的 basename 与最终点号语义。`classifyFileType(path)` 不区分大小写，并返回闭合的 `FileType` 联合：传统的 `code`、`excel`、`folder`、`html`、`image`、`markdown`、`other`、`pdf`、`ppt`、`video`、`word` 类别，以及从所提供 `square-code-icons` 映射接入的细分 `CodeFileType` 集合。解析按完整文件名、文件名前缀、文件名后缀、可选项目上下文、扩展名的顺序执行。路径分类器返回 `folder` 之外的全部成员；调用方确认条目是目录时，通过 `FileTypeIcon` 的显式 `type` 覆盖指定目录。未知扩展名、无扩展名和末尾点号回退到 `other`，但共享表识别 `Dockerfile`、`Makefile`、`package.json`、`.gitignore`、`README`、`CHANGELOG` 等具名文件。

 `FileTypeIcon` 接受路径、共享 `IconProps`、可选的显式类型和可选的项目文件快照。传统文件类型把所提供的 28px 文档与文件夹轮廓渲染为 inline SVG。Excel、Markdown、PDF、PPT、Word 的前景标记围绕自身视觉中心缩放至 122%，其余带标记的传统图形使用 112%；文件底板与折角保持源图几何，通用文件不凭空增加中心标记。底板使用实色分类颜色，前景标记与普通折角使用白色，通用文件使用较深的灰色折角。CSS 通过静态设计 token 分配所提供的分类调色板：code/HTML/Markdown 使用 DeepSeek 蓝，Word 使用较浅的 DeepSeek 蓝，Excel 使用绿色，folder/PPT 使用两档琥珀色，PDF 使用红色，未知文件使用中性灰。image 与 video 通过组件本地变量共用所提供的紫色，因为设计平台没有匹配的紫色 token。调用方可通过 `--dsh-file-type-icon-color` 覆盖传统底板颜色。

 ### Controls and icons
 
-The catalog above lists what each export is for; this section covers the behavior that props alone do not show. The `ic_ds_*` icon set and `FishLogo`/`BrandWordmark` marks fill brand and inline-icon slots. `FileTypeIcon` renders the traditional 28px Excel, folder, HTML, image, Markdown, generic, PDF, PPT, video, and Word glyphs, and uses the full-color square technology artwork for recognized code and configuration files. `classifyFileType` applies exact filename, prefix, suffix, optional project-context, and extension rules in that order; React names win over TypeScript/JavaScript, Angular suffixes win over their base extension, and a Dart file becomes Flutter only when the supplied project files contain a `pubspec.yaml` with `flutter:`. Markdown and SVG remain traditional Markdown and image files. `fileExtension` exposes the same basename and final-dot parsing for adjacent metadata labels. Traditional glyphs use a solid category-colored sheet with a white mark and translucent white corner; the generic file uses a grey sheet and darker grey corner. Callers may override the sheet color through `--dsh-file-type-icon-color`. The full-color technology artwork is the deliberate exception and retains its embedded palette. All glyphs are decorative and carry no label. `LinkIcon` remains the smaller leading glyph for clickable artifact links — globe, folder, code, image, document, or plain paper — while `classifyLinkPath` folds the shared file types into that existing six-category vocabulary. `ConnectionIndicator` renders a warning-colored disconnected action, a connecting label whose one-to-three dots advance every 500ms independently of retry timing, or a success-colored recovered status. Hover or keyboard focus shows only the reconnect action label, including while the connecting dots animate. Every state reserves the widest supplied label and uses fixed icon and text columns, so copy changes do not move or resize the control. Its owner supplies visibility, the recovery hold, localized labels, and the immediate-reconnect callback; the primitive uses no native title tooltip. `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. `Toast` holds for the window its owner names through `holdMs`, because how long a banner has to stay depends on how much there is to read; the same value drives its unmount timer and the stylesheet's fade delay, so the two cannot disagree. `rankByName` is the `/` menu's shared candidate ranker for the command and skill sources: the query must be a case-insensitive ordered subsequence of the name; prefix hits rank first, then alignment score, then source order. `Menu.autoFocus` focuses its first enabled item, supports Arrow Up/Down and Home/End navigation, and focuses the first button in the anchor on Escape; it is opt-in for action menus.

 - The docking surface itself no longer overflows its panel: `.surface` and `.pane` clamp to the column (`min-width: 0`, `overflow: hidden`), so a long unwrapped line scrolls inside the body and the strip's controls stay in view in every split.
 - Layout is undoable and per session, and it is memory-only; a reload starts every session collapsed. Undo is reachable only through `@internal` service methods; the product shows no history controls.
-- A pane cannot be left empty and the surface cannot be left tabless: closing, moving out, or floating a pane's last tab drops the pane, and emptying the last pane restores the current default page.
+- An expanded surface has no empty panes. Empty side panes merge away; an empty root receives the current default page only while expanded. New sessions and a collapsed surface whose last tab closed remain empty until expansion.
 - A pane holds at most one guide tab: a second one cannot be added, opened, duplicated, or moved in; the guide's uniqueness is per pane, so a split still seeds its new pane with a guide.
 - A pane may split only when each equal half can still hold what cannot shrink: the strip's fixed controls (its width minus the chip box and the fill, so the top-right pane's chrome counts on the half that hosts it) plus one chip at its minimum, measured in the component layer after every commit and on resize. Otherwise the split control stays, disabled with its own copy, the matching edge drop zones are withheld, and panes the user narrows keep their size; the product permits at most two horizontal panes, regardless of widening or divider movement.
 - The Sidebar panel never moves when the presentation switches, and its slide is the same in both presentations; the conversation is the only thing that animates on a switch. A hidden panel keeps its tabs mounted, so a preview survives a collapse.

-The docked surface's last tab carries one rule, decided in the Sidebar store's `closeTab` and mirrored to the kit through a new `canCloseTab(tabId)` control-policy prop (joining `canSplit` and `canAddTab`): the guide standing as the only docked tab is unclosable — no chip close control, no menu close item, and a programmatic close records nothing; any other lone tab closes together with the column in one history entry, resets fullscreen to push mode, and lets the settle planner prepare the current default page for the next expansion. `soleDockedTab(state, tabId)` in [stores.ts](../../../../packages/client/ui-sidebar-right/src/client/stores.ts) names the condition; floating panels take no part in it. Per the packages rule "enforce a decision in the operation that makes it", the store's `closeTab` is the enforcement and `canCloseTab` only mirrors it into the chrome. This rule supersedes the close-protection part of [the default-page decision](2026-09-08-sidebar-default-pages.md); its selection rule remains active.

Splitting an empty pane is a no-op: it mints no tabs, records no history, and reports no new pane.
 
 **Page uniqueness is pane-scoped.** The guide-only merge generalized to every page kind (`pageKind`/`panePage`): opening a page focuses an existing tab only inside the pane the open targets, and a page dragged, dropped, or docked into a pane already showing that kind's page merges into the pane's own. Resource tabs keep the kit's surface-wide reveal.

 After every action the kit's settle planner keeps the expanded surface populated: a docked pane whose last tab was moved out or floated is merged away, and an emptied root pane receives the default page. A collapsed surface holds no such backfill — a session starts collapsed and empty, and a close that collapses the column leaves it empty — the expansion that would first show an empty layout is what seeds the default page. Explicit closing follows [the default-page and close rules](#the-guide). While expanded there is always at least one tab, and never an empty pane — so there is no separate "close pane" gesture.
 
-The docked surface's last tab carries one more rule, decided in the store's `closeTab` and mirrored to the kit through `canCloseTab`: the guide standing as the only docked tab draws no close control and no menu close item — its chip sits quiet, and with no extension item contributed a secondary press opens no menu — and a programmatic close of it records nothing; any other tab standing alone closes together with the column in one entry — the settle planner reseeds the current default page for the next expansion. Floating panels take no part in the rule: they render whether or not the column is expanded, and their tabs close freely.

Then the Tab domain records the navigation — `params` reach the body as `navigation.params`, with `revision` stepped — outside the layout history. `params` is typed by what is opened: a viewer for a resource type merges its entry into `SidebarRightResourceParamsMap` (the text preview declares `{ line?: number }`); a page type that takes parameters merges into `SidebarRightTabParamsMap` under its kind; values are JSON-shaped by convention, unchecked at run time.

 `close(tabId)` closes a tab; `active()` reads the active tab. `isExpanded()` and `toggleExpanded()` read and drive the column's expansion; the presentation switch is the panel's own control and not part of this face. Layout operations, for callers that arrange the column programmatically, each recorded like the gesture it stands in for: `focus(tabId)` focuses a tab and its pane; `split(paneId?)` splits a docked pane (the active one by default) under the same pane budget and room rule as the strip's control and returns the new pane's id, or `undefined` — recording nothing — when it cannot; `float(tabId, rect?)` takes a docked tab out into a panel; `dock(paneId)` returns a floating panel to the active docked pane. A tab or pane that does not exist, or already is where the call would put it, is left alone. The face exposes operations only: no layout snapshot, no operation log, no lookup by address. `_undo()` / `_redo()` step the mounted surface's history; they are `@internal` — the sequence has no user-facing control, and these exist for tests. Commands need a mounted session surface; with none, they throw rather than write into a surface nobody draws.

 Default pages depend on the number of registered guide entries, not the number of tab types or open tabs. Exactly one entry opens its page directly (Files in the shipped composition); zero or multiple entries open the guide. Explicitly adding a guide still opens the guide, even with one entry. The sole docked guide is the only tab that cannot close; closing any other sole tab also collapses the column. The chip, context menu, and `close` API apply the same rule.
 
-The guide tab is one entry capsule (a glyph and a title, nothing else) per `guide` entry the registered types contributed, in `order`, centred in the body; the guide has no words of its own. Picking a capsule calls `tab.actions.openTab(entry.kind, { replaceTab: true })`, so the guide gives way to the page it opened. A pane holds at most one guide tab. The strip's add control is drawn only while its pane holds none and opens one there with `openTab('guide', { paneId, revealIfOpened: false })`, so a guide in another pane does not capture the click; opening the guide into a pane that already has one focuses it instead; a guide dragged, dropped, or docked into such a pane merges into it — the arriving guide closes and the pane's own is focused; `duplicateTab` on the guide records nothing. A split, an emptied root pane, and the pane a sole tab vacates by dropping on its own edge use the same default-page rule, one tab per new pane; the self-edge drop leaves the dragged tab focused. A plain `openTab('guide')` keeps the tree-wide reveal every open has. The product allows two horizontal panes, initially equal, with divider ratios limited to 20%–80%. Insufficient width blocks a new split; with two panes already present, a body drop moves the tab between panes instead of creating a third. At the two-pane limit, split controls are hidden; closing back to one pane restores them.

 `FileTypeIcon` accepts a path, shared `IconProps`, the explicit `kind`, and an optional project-file snapshot. Traditional file types render the supplied 28px document and folder contours as inline SVG. Excel, Markdown, PDF, PPT, and Word foreground marks scale to 122% around their visual center; the remaining marked traditional glyphs use 112%, while the file body and folded corner retain their source geometry and the generic file has no invented center mark. The sheet is a solid category color, the foreground mark and ordinary folded corner are white, and the generic file has a darker grey corner. CSS assigns the supplied category palette through static design tokens: DeepSeek blue for code/HTML/Markdown, the lighter DeepSeek blue for Word, green for Excel, two amber steps for folder/PPT, red for PDF, and neutral grey for unknown files. Image and video share the supplied violet through a component-local variable because the design platform has no matching violet token. A caller may override a traditional sheet through `--dsh-file-type-icon-color`.
 
-Recognized code and configuration files render the corresponding 20px square artwork scaled to the requested icon size. These technology marks retain their embedded multicolor fills and are the explicit exception to the ordinary current-color icon rule. The map selects React before TypeScript/JavaScript, Angular filename suffixes before their base extension, Docker/Node/Git/Make/CMake by filename rules, and Flutter only when the optional project snapshot contains a `pubspec.yaml` whose text includes `flutter:`. Markdown and SVG remain owned by the traditional Markdown and image categories. Every traditional and technology SVG is `aria-hidden`, and the card, row, or button that owns the file identity supplies the accessible name.

Both `.env` and names ending in `.env` use the environment glyph. Every traditional and technology SVG is `aria-hidden`, and the card, row, or button that owns the file identity supplies the accessible name.
 
 `LinkIcon` delegates extension classification to `classifyFileType` and folds the detailed result into its existing link vocabulary: code and HTML use `code`, images use `image`, PDF/Word/Excel/PPT use `document`, and Markdown/video/unknown files use `other`. Extensionless names remain `other` in link contexts, so the 14px clickable-link appearance defined by the [clickable-link decision](2026-09-04-web-clickable-link-styles.md) does not change.
 
-Attachment upload cards, sent-message file cards, queued-file rows, and workspace file rows render `FileTypeIcon`. Explicit delivery cards also use `FileTypeIcon` at 28px and `fileExtension` for their fallback metadata. The two metadata rows use `fileExtension` rather than local parsers; a leading-dot basename such as `.env` therefore displays `ENV`, while an absent or trailing suffix displays no extension label. Image content continues to render as a preview rather than a file-type glyph, and produced-file links and Markdown file mentions continue to use `LinkIcon` because they are link surfaces.

 `LinkIcon` 委托 `classifyFileType` 做扩展名分类，再把精细结果折叠进原有链接词汇：code 与 HTML 使用 `code`，图片使用 `image`，PDF/Word/Excel/PPT 使用 `document`，Markdown、video 与未知文件使用 `other`。无扩展名文件在链接语境中仍是 `other`，因此[可点击链接决策](2026-09-04-web-clickable-link-styles.zh.md)定义的 14px 外观不变。

+# Agent Note: Content-sized diagram previews
+
+Status: implemented
+
+English | [中文](2026-09-09-content-sized-diagram-previews.zh.md)
+
+## Problem
+
+Short Graphviz and SVG images leave large empty regions when displayed inside 400px frames. A 59px Graphviz diagram occupies a 400px preview even though its rendered dimensions are already available to the browser.
+
+## Decision
+
+Mermaid, Graphviz, and SVG share the inert image canvas in `SourcePreview`. The browser derives its height from the image, preserves aspect ratio when shrinking to the available width, and adds 16px padding. Source switching retains the image and copying reads the original code. Theme changes regenerate Graphviz colors without introducing a separate sizing observer.
+
+This replaces the diagram-frame choice in [Static Markdown fence previews](../feature/2026-09-09-markdown-static-previews.md); that note continues to own HTML isolation, rendering lifecycle, and license obligations. HTML retains its opaque, script-free, 400px frame. SVG image mode disables scripts, link interaction, and external resource loading without inserting source-controlled markup into the application document.
+
+## Alternatives considered
+
+**Set iframe height to auto.** An iframe does not derive its outer height from its inner document. This still reserves an unrelated viewport.
+
+**Add a frame measurement script or same-origin access.** A diagram already has image dimensions. Extra execution or origin permissions and resize messaging are unnecessary for that content.
+
+## Consequences
+
+Short diagrams occupy only their rendered height and canvas padding. The browser geometry regression compares image and container height in light and dark modes, then verifies proportional scaling in a narrow viewport. Browser security checks include SVG scripts, event handlers, nested HTML, and external images; copy and source toggling remain covered. HTML automatic height remains outside this change because arbitrary document layout has different measurement and isolation requirements.

+# Agent Note: 按内容定高的图表预览
+
+Status: implemented
+
+[English](2026-09-09-content-sized-diagram-previews.md) | 中文
+
+## Problem
+
+较矮的 Graphviz 与 SVG 图片显示在 400px iframe 中时，会留下大块空白。浏览器已经知道图片的渲染尺寸，但一张 59px 高的 Graphviz 图表仍占据 400px 的预览区域。
+
+## Decision
+
+Mermaid、Graphviz 与 SVG 共享 `SourcePreview` 的不可执行图片画布。浏览器根据图片决定高度，在可用宽度不足时按比例缩小，并添加 16px 内边距。源码切换保留图片，复制读取原始代码。主题变化重新生成 Graphviz 配色，无需单独的尺寸观察器。
+
+这替代了[静态 Markdown fence 预览](../feature/2026-09-09-markdown-static-previews.zh.md)中的图表 iframe 选择；该记录继续维护 HTML 隔离、渲染生命周期与许可证义务。HTML 保留不透明来源、禁用脚本的 400px iframe。SVG 图片模式禁用脚本、链接交互与外部资源加载，无需把源码控制的标记插入应用文档。
+
+## Alternatives considered
+
+**把 iframe 高度设为 auto。** iframe 不会根据内部文档决定外部高度，仍然会保留与内容无关的视口。
+
+**添加 iframe 测量脚本或同源访问。** 图表已经具备图片尺寸，不需要额外执行权限、来源权限或尺寸消息协议。
+
+## Consequences
+
+较矮图表只占据渲染高度与画布内边距。浏览器几何回归用例在浅色和深色下比较图片与容器高度，再验证窄视口中的等比例缩放。浏览器安全检查包含 SVG 脚本、事件处理器、嵌套 HTML 与外部图片，并保留复制和源码切换覆盖。HTML 自动高度不属于本次改动，因为任意文档布局具有不同的测量与隔离要求。

 Mermaid loads on demand. A shared queue serializes theme initialization with diagram work, and each call removes its temporary measurement DOM in `finally`. Strict security, disabled HTML labels, the application palette, and error-rendering policy cannot be overridden by diagram configuration. Generated SVG is displayed as an image without installing links or scripts. Intrinsic dimensions come from the SVG viewBox; large diagrams shrink to fit, and the canvas follows the code-block background. Mounted previews observe document theme attributes and regenerate only when resolved colors change; obsolete renders cannot publish. Graphviz default colors follow the same palette, while authored DOT, SVG, and HTML colors remain intact.
 
-HTML uses DOMPurify with navigation attributes and document-loading elements forbidden, followed by an opaque `sandbox=""` iframe. A trusted CSP precedes source markup and permits only inline CSS, data images, and data fonts. Scripts, external resources, child frames, form submission, and same-origin access are unavailable. SVG is parsed as XML and placed in an image inside the frame, so SVG scripts and links never become active. Frames have a fixed scrollable viewport: measuring their content would require additional origin access or trusted frame scripts.

 Graphviz uses the pinned, unmodified `@viz-js/viz` 3.30.0 WebAssembly distribution with the `dot` layout engine. Its npm MIT declaration covers the wrapper; its build provenance identifies Graphviz 16.0.0 (EPL-2.0), Expat 2.8.4 (MIT), and Emscripten 5.0.7 (MIT/NCSA). Distribution retains these component terms and the exact Graphviz source download under EPL-2.0 section 3.1. [Full preview notices](../../../../packages/client/ui-primitives/THIRD_PARTY_PREVIEW_NOTICES.txt) also retain Mermaid's MIT text and select Apache-2.0 for DOMPurify. The UI primitives package ships the notices and the Web build emits the same bytes alongside its assets. License review covers embedded payloads separately from the general permissive npm-metadata policy.

 `present` accepts existing regular files accessible through its composed `ctx.fs`, with relative paths resolved against the Session working directory. There is no workspace containment check or special temporary-directory allowlist. Missing files, directories, final symbolic links, and provider failures reject the declaration. A sandbox's private temporary files remain unavailable when the filesystem provider cannot see them.

This conservatively supports Host paths that share their canonical process spelling; providers with only a nonidentity Host mapping can still serve previews. A same-named local file never substitutes for an unmapped provider file.
+Native actions use the viewed Session header returned with the declaration to form the `workspaceFiles.stat` scope: its cwd, or the deployment workspace root when absent. The same composed filesystem serves Sidebar previews and native validation without activating an Agent, including for child Sessions. The resulting canonical process path must map from a Host path back to the same process path through that filesystem. Absent or different mappings produce 422 and a localized Sidebar-preview suggestion. This conservatively supports Host paths that share their canonical process spelling; providers with only a nonidentity Host mapping can still serve previews. A same-named local file never substitutes for an unmapped provider file.
 
 This replaces the workspace-only access rule in the [source-file delivery decision](2026-09-08-present-workspace-source-files.md). That note continues to own content-free declarations, Session events, and editing current sources. The request still selects only saved Session/event/file coordinates, never an arbitrary browser-supplied path.

 The Node half registers the static `ui:deliverable-file-references` system-prompt section asking the model to mention primary files from successful creation or modification calls and to write those and any other changed-file references as Markdown inline code. The browser half registers a wrapper around `ProducedFiles` and explicit deliveries into the chat view's `conversation.chat.turnTail` hole. `deliverablesDefinition` folds each Turn's successful first-party mutation calls into `DeliverablesTurnData` from the validated raw arguments of `write`, `edit`, and mutating `str_replace_editor` commands. Reads, deletes, unsupported tools, malformed calls, and failed results contribute nothing. A new mutation tool needs an explicit Client contribution before it joins the list. The package also provides the `chatFileMentions` service the chat view consults per closing message; composing the plugin out removes both surfaces and leaves the view's empty chain at zero cost.

+Native opening uses an authenticated POST addressed by the viewed Session, event sequence, and original file index. The Host reads the viewed Session header with the declaration and passes its cwd, or the deployment workspace root when absent, to `workspaceFiles.stat`. This uses the same composed filesystem as Sidebar previews and does not activate an Agent, including for child Sessions.

 The three primary Linux jobs (`node-24`, `node-24-coverage`, `node-24-consumers`), the three `node-compat` matrix entries, and `all-checks-passed` resolve through `DSH_CI_FAILOVER_LINUX`; the native Windows jobs resolve through `DSH_CI_FAILOVER_WINDOWS`. A platform switch does not redirect the other platform. Set to `selfhosted` by a repository writer, the applicable trusted jobs select `vm-backup` or `dsh-win-ci`; otherwise they retain their workflow-defined hosted fallbacks. Node compatibility jobs require a same-repository, non-fork head and a non-Dependabot author, use isolated runtime setup, and retain `ubuntu-latest` fallback. Linux failover bounds snapshot concurrency and skips hosted package-cache restores. The verdict follows its workers so it does not remain queued on an unavailable hosted pool. Each switch is writer-manageable repository state, not a merge, so it works while checks are red. The `serial / linux (self-hosted standby)` and `serial / windows (self-hosted standby)` lanes re-prove the complete unsharded aggregates on master pushes.
 
-`ci-master.yml` exempts exactly one event from `cancel-in-progress` (`${{ github.event_name != 'push' }}`), so one master push does not cancel the drill still running from the previous one. Each drill runs its complete unsharded aggregate with one gate worker, which takes longer than the interval between master merges; under unconditional cancellation a drill is superseded before reaching a verdict and the lane yields no readiness evidence for a responder to check.
-
-The exemption is narrower than "a drill always finishes", in two ways. GitHub keeps a single pending entry per group, so a newer pending run displaces an older one and intermediate push runs still end as `cancelled` during busy periods. And the expression is evaluated against the *newly triggered* run, so a run whose own event is not `push` — a benchmark dispatched on master within `ci-master.yml`, sharing its group `CI master-<ref>` — evaluates to `true` and does cancel a drill that is mid-flight. That is a rare manual action and the next master push restores the evidence, so it does not warrant further mechanism. What the carve-out buys is that the lane periodically reaches a verdict at all, which is what makes it usable as evidence.
-
-The decision belongs at workflow level because cancellation applies to the whole superseded run: a job-level `concurrency` group does not exempt its job. The negated form is load-bearing rather than cosmetic: naming `pull_request` alone would also stop cancelling `workflow_dispatch`, and each runner benchmark fans out to twelve larger runners for up to fifteen minutes inside this same group on master, so a re-dispatch would queue ahead of a drill instead of replacing a stale measurement. What bounds the cost is that a master push in `ci-master.yml` carries the [post-merge runtime and Wine checks](2026-09-06-master-only-platform-ci.md) and these two drills; the pull-request jobs live in the separate `ci.yml` (which does not see `push`), and the benchmarks are `workflow_dispatch`-gated within `ci-master.yml`. `scripts/ci-workflow.spec.ts` pins that push-reachable set — classifying by exact condition, since a negated event test mentions the event it excludes — so a new push-reachable job cannot quietly start accumulating uncancelled runs.
+The [superseded-CI cancellation policy](2026-09-09-cancel-superseded-ci.md) governs master pushes and manual runs in the same workflow/ref group, including standby drills. Rapid master updates can starve a drill before it reaches a verdict. Use the latest completed standby verdict and check its age and commit before treating it as readiness evidence; a cancelled or merely scheduled run is not proof of readiness.

 ## Consequences
 
-Recovering from a hosted-pool outage is flipping the affected platform's variable (any writer) plus a re-run, with no merge on the critical path. The cost is a second runner topology per platform to keep working: the standby lanes exercise them on every master push so the failover targets never go stale, and the snapshot-concurrency and cache-restore branches in `ci.yml` carry a `selfhosted` leg (Linux only) that must stay in step with the hosted leg. Splitting the switch by platform adds one more variable to manage but bounds the blast radius of each switch to the jobs of a single platform.

+# Agent Note: Cancel superseded CI validation
+
+Status: implemented
+
+English | [中文](2026-09-09-cancel-superseded-ci.zh.md)
+
+## Problem
+
+Validation of an obsolete PR revision or master commit consumes runner capacity without establishing the newest revision’s status. Unconditional aggregate verdicts and coverage-history uploads can also keep cancelled runs doing bookkeeping. Preserving older post-merge runs favors historical completion over current validation, especially on the shared self-hosted pools.
+
+## Decision
+
+Validation favors the newest run within each workflow/ref group. [CI](../../../../.github/workflows/ci.yml), [CI master](../../../../.github/workflows/ci-master.yml), [real-API e2e](../../../../.github/workflows/e2e.yml), and the credential-free [dsh](../../../../.github/workflows/release.yml) and [vendor](../../../../.github/workflows/release-vendor.yml) pack validations use `cancel-in-progress: true` with `${{ github.workflow }}-${{ github.ref }}`. Different PR refs and different workflows do not cancel each other. Event type is not part of the group: master pushes and manual benchmarks can supersede each other in CI master, and e2e pushes, scheduled runs, and manual runs can supersede each other on the same ref.
+
+The [reusable Python runtime builder](../../../../.github/workflows/build-exe-for-python-sdk.yml) uses `${{ !inputs.release }}`. Its `build-single-exe-${{ github.workflow }}-${{ github.ref }}` group remains distinct from its caller’s group, and the caller workflow name isolates ordinary CI from release-owned builds. Release-owned builds are exempt because they belong to an intentional publication transaction. Publication, deployment, and metadata workflows retain their own policies; this decision does not apply cancellation indiscriminately across workflows.
+
+The PR aggregate uses `${{ !cancelled() && github.event_name == 'pull_request' }}`. The explicit status function preserves evaluation after failed or skipped dependencies rather than accepting GitHub’s default success-only condition. The aggregate still fails on any failure, cancellation, or skip among its dependencies when the workflow itself is not cancelled; cancellation of the whole workflow suppresses its obsolete verdict. Coverage duration history uses `!cancelled()` too: failed coverage can still save useful measurements, but cancelled coverage does not upload them. Wine’s `always()` cleanup remains necessary resource cleanup rather than optional bookkeeping.
+
+This reverses the cancellation exemption in the [failover runbook](2026-07-26-ci-failover-runbook.md), [master-only platform CI](2026-09-06-master-only-platform-ci.md), and [real-API e2e decision](../testing/2026-06-19-real-api-e2e-ci.md). Those notes retain independent value for pool trust and switching, platform coverage, and secret exposure. The [release rehearsal decision](2026-09-06-release-rehearsal-selfhosted.md) retains runner selection and isolation ownership. None is fully superseded or archived.
+
+## Alternatives considered
+
+**Preserve running master-push drills.** The former `${{ github.event_name != 'push' }}` exemption favored periodic readiness evidence: each standby executes its complete unsharded aggregate with one gate worker and can outlast the interval between master merges. Even that policy did not guarantee every drill completed. GitHub retains one pending run per group, replacing intermediate pending pushes; cancellation is evaluated on the newly triggered run, so a manual benchmark sharing the master group could still cancel a drill. That rare manual interruption was accepted on the expectation of evidence from a subsequent push. The exemption’s cost was bounded by the master-only runtime checks, Wine, and two drills; PR jobs remained in a separate workflow, and exact-condition regression checks pinned the push-reachable job set. This policy is rejected in favor of freeing capacity for current validation, explicitly accepting standby starvation.
+
+**Protect a drill with job-level concurrency, or cancel only PR events.** A job-level group cannot exempt a job from cancellation of its entire workflow. A PR-only cancellation condition also exempts manual dispatch: a repeated runner benchmark can occupy twelve larger runners for up to fifteen minutes rather than replacing an obsolete measurement. Workflow-level cancellation covers both pushes and manual runs.
+
+**Keep every post-merge, nightly, and pack run.** Historical completion provides more per-commit and per-trigger evidence, but obsolete validation competes with the newest run. These validations do not publish packages, so preserving every run is not the same requirement as protecting an intentional publication transaction.
+
+**Replace every `always()` condition.** Failure aggregation and resource cleanup have different obligations. A success-only aggregate can hide failed dependencies behind a skipped required check; removing unconditional Wine cleanup can leave resources running. Only cancelled-run bookkeeping is suppressed.
+
+## Consequences
+
+Rapid master updates can repeatedly cancel the longer standby drills before they produce a verdict. Operators use the latest completed standby verdict, checking its age and commit before relying on it for failover readiness; a scheduled, running, or cancelled drill is not readiness evidence. The policy does not guarantee that every intermediate commit, nightly trigger, or benchmark completes. Different refs can still compete for shared host capacity.
+
+Cancellation is a request handled by GitHub Actions and its runners, not a guarantee of immediate termination or bounded queue delay. Cleanup can still take time. The policy makes obsolete validation cancellable; it does not promise a fixed runtime or cancellation latency.
+
+## Verification
+
+[Workflow regressions](../../../../scripts/ci-workflow.spec.ts) pin workflow/ref isolation, release-owned exemptions, aggregate status conditions, coverage-history cancellation, and retained Wine cleanup. [Platform routing regressions](../../../../scripts/tests/ci-master-platforms.spec.ts) preserve the master/PR target split and release matrix; [release rehearsal regressions](../../../../scripts/tests/ci-release-selfhosted.spec.ts) preserve cancellation alongside runner eligibility and publication isolation. These configuration checks do not reproduce GitHub scheduling or runner shutdown. Live supersession and completed standby evidence remain CI verification responsibilities.

+# Agent Note: 取消被取代的 CI 验证
+
+Status: implemented
+
+[English](2026-09-09-cancel-superseded-ci.md) | 中文
+
+## 问题
+
+验证已被取代的 PR（Pull Request）修订或 master 提交会消耗运行器容量，却不能确定最新修订的状态。无条件执行的聚合判定和覆盖率耗时历史上传，还可能让已取消的运行继续处理记账任务。保留旧的合并后运行，意味着优先完成历史验证而非当前验证，在共享自托管池上尤其如此。
+
+## 决策
+
+验证优先保留各工作流/引用组内最新的运行。[CI](../../../../.github/workflows/ci.yml)、[CI master](../../../../.github/workflows/ci-master.yml)、[真实 API e2e](../../../../.github/workflows/e2e.yml)，以及无凭据的 [dsh](../../../../.github/workflows/release.yml) 和 [vendor](../../../../.github/workflows/release-vendor.yml) 打包验证，均在 `${{ github.workflow }}-${{ github.ref }}` 组中使用 `cancel-in-progress: true`。不同 PR 引用和不同工作流不会相互取消。事件类型不参与分组：CI master 中的 master 推送与手动基准测试可以相互取代，e2e 的推送、定时运行和手动运行也可以在同一引用上相互取代。
+
+[可复用 Python 运行时构建器](../../../../.github/workflows/build-exe-for-python-sdk.yml)使用 `${{ !inputs.release }}`。其 `build-single-exe-${{ github.workflow }}-${{ github.ref }}` 组与调用方的组保持区分，调用方工作流名称将普通 CI 与发布所属的构建隔离。发布所属的构建获得豁免，因为它们属于一次有意发起的发布事务。发布、部署和元数据工作流保留各自的策略；本决策不会不加区分地对所有工作流应用取消。
+
+PR 聚合使用 `${{ !cancelled() && github.event_name == 'pull_request' }}`。显式状态函数使其在依赖失败或跳过后仍然求值，而非采用 GitHub 默认的仅成功条件。当工作流本身未被取消时，聚合仍会因任意依赖失败、取消或跳过而失败；整个工作流被取消时则抑制其已失去用途的判定。覆盖率耗时历史也使用 `!cancelled()`：覆盖率失败时仍可保存有用的测量数据，但被取消的覆盖率运行不上传。Wine 的 `always()` 清理仍是必要的资源清理，而非可选记账任务。
+
+本决策推翻[故障切换手册](2026-07-26-ci-failover-runbook.zh.md)、[仅 master 执行的平台 CI](2026-09-06-master-only-platform-ci.zh.md) 和[真实 API e2e 决策](../testing/2026-06-19-real-api-e2e-ci.zh.md)中的取消豁免。这些记录对运行器池信任与切换、平台覆盖和密钥暴露仍有独立价值。[发布演练决策](2026-09-06-release-rehearsal-selfhosted.zh.md)仍负责运行器选择与隔离。没有记录被完全取代或归档。
+
+## 曾考虑的替代方案
+
+**保留正在执行的 master 推送演练。** 原有 `${{ github.event_name != 'push' }}` 豁免优先保证周期性就绪证据：每条热备以单门禁工作进程执行完整的未分片聚合流程，耗时可能长于 master 合并间隔。即便该策略也不保证每次演练完成。GitHub 每个组仅保留一个待运行条目，会替换中间的待执行推送；取消条件针对新触发的运行求值，因此共享 master 组的手动基准测试仍可取消演练。当时接受了这种罕见的手动中断，期望后续推送提供证据。豁免成本被限定为仅 master 执行的运行时检查、Wine 和两条演练；PR 作业仍在独立工作流中，按精确条件匹配的回归检查固定推送可达作业集合。为释放容量给当前验证而否决该策略，明确接受热备因反复被取消而无法完成。
+
+**用作业级并发保护演练，或仅取消 PR 事件。** 作业级分组不能让作业免于整个工作流的取消。仅针对 PR 的取消条件还会豁免手动触发：重复派发的运行器基准测试可能占用十二台大型运行器长达十五分钟，而非替换陈旧的测量。工作流级取消同时覆盖推送和手动运行。
+
+**保留每次合并后、每夜和打包运行。** 完成历史运行能提供更多按提交和触发划分的证据，但已被取代的验证会与最新运行竞争。这些验证不发布包，因此保留每次运行与保护有意发起的发布事务并不是同一项要求。
+
+**替换每个 `always()` 条件。** 失败聚合与资源清理承担不同义务。仅成功时执行的聚合可能把依赖失败隐藏为跳过的必需检查；移除无条件 Wine 清理则可能留下仍在运行的资源。只有已取消运行的记账任务被抑制。
+
+## 后果
+
+master 快速更新可能反复取消耗时更长的热备演练，使其无法产出结论。运维人员使用最近一次已完成的热备结论，并在依赖它判断故障切换就绪状态前核对其时间和提交；已调度、正在执行或已取消的演练都不构成就绪证据。该策略不保证每个中间提交、每夜触发或基准测试都能完成。不同引用仍会竞争共享主机容量。
+
+取消是由 GitHub Actions 及其运行器处理的请求，不保证立即终止或限定排队时长。清理仍可能耗时。该策略让已被取代的验证可以被取消，但不承诺固定运行时长或取消延迟。
+
+## 验证
+
+[工作流回归测试](../../../../scripts/ci-workflow.spec.ts)固定工作流/引用隔离、发布所属构建豁免、聚合状态条件、覆盖率历史取消及保留的 Wine 清理。[平台路由回归测试](../../../../scripts/tests/ci-master-platforms.spec.ts)保留 master/PR 目标划分与发布矩阵；[发布演练回归测试](../../../../scripts/tests/ci-release-selfhosted.spec.ts)在验证取消策略的同时保留运行器准入与发布隔离。这些配置检查不重现 GitHub 调度或运行器停止过程。真实运行取代行为与已完成热备证据仍由 CI 负责验证。

+The job runs only `test:e2e` on Node 24; keyless gates and version compatibility belong to the main CI workflow. Tests run unbuilt through the workspace paths map with a bounded configurable worker pool, per-test retries, and a job timeout. The [superseded-CI cancellation policy](../process/2026-09-09-cancel-superseded-ci.md) cancels older runs in the same workflow/ref group across PR, push, schedule, and manual triggers; a post-merge or nightly trigger does not guarantee completion.
 
 The DeepSeek native `web_search` probe is registered but skipped. The live Anthropic-compatible endpoint can return a successful response without structured source blocks, so its positive-source assertion is not a reliable merge signal; unit coverage still pins response parsing, but CI does not prove the live source-block wire shape.

@@ -26,7 +26,7 @@ The browser worker host: the whole harness plugin tree runs inside one dedicated
 Three artifacts from one tsdown pipeline:
 
 - **`lib/index.js` (assembly library)** — `createWorkerHost`/`startWorkerHost` mount the base image and any ordered data overlays (`storage/`), install the module loader (`module-system/`) and the `process` shim, boot the tree through the image's own `dsh-app-boot`, and hand the tunnel its serving seams. Overlays may replace files only under `home/` and `workspace/`; they cannot replace the base manifest, configuration, or modules. The image layout contract (`image-layout.ts`: virtual root, config/manifest paths, empty directories, the `lowered` wrapper-contract gate) is shared with the packer. Boot patches force the deployment-shaped rows: frontend serving off, JSONL session logs on the plaintext path, preset roots onto the image's `config/agent-presets`.
-- **`lib/worker.js` (worker bundle)** — the assembly plus this package's Node-compatibility layer as one self-contained ES module. The module proxy table (`module-proxies.ts`) is the only platform fork: `node:*` builtins over VFS/tunnel/browser primitives, structural stubs that fail loud on the console for what a browser cannot do, and native/binary package replacements. `node:module` supplies `createRequire().resolve` and `.resolve.paths()` over the image package root, so unchanged packages can discover manifests without evaluating their modules. The global `process` shim carries Node detection fields including `title`, preventing Worker execution from entering DOM-only branches. The pack-time parser reports statically named module requests, including module-scope direct calls of the form `createRequire(import.meta.url)('pkg')` through a named `node:module` or `module` import, to the packer's reachability walk. Stored, CommonJS-obtained, and rebased `createRequire` calls require image entry seeds. VFS mutations drive `node:fs` callback, polling, and promise watchers; open descriptors retain file identity and access mode across rename, replacement, and unlink; `readable-stream` supplies the stream state machine used by file streams and unchanged image packages such as Chokidar and readdirp. AsyncLocalStorage carries sync-stack causality across `await` through the snapshot/restore faces the pack-time lowering injects. The worker holds no compiler: an image the packer did not lower is refused at mount.

VFS mutations drive `node:fs` callback, polling, and promise watchers; open descriptors retain file identity and access mode across rename, replacement, and unlink, and `FileHandle.stat({ bigint: true })` reports the same device and inode identity as a path stat while the name still refers to that file; `readable-stream` supplies the stream state machine used by file streams and unchanged image packages such as Chokidar and readdirp. AsyncLocalStorage carries sync-stack causality across `await` through the snapshot/restore faces the pack-time lowering injects. The worker holds no compiler: an image the packer did not lower is refused at mount.
 - **`src/shell/` (the worker's own process layer)** — a browser worker cannot fork, so `node:child_process` is not a stub but an implementation: `spawn` starts the command in its own Web Worker — this same bundle, told by its first frame to be a shell process — and reports it through the `ChildProcess` surface the subprocess service consumes. The command runs off the host's thread, `SIGKILL` terminates it whatever it is doing, and it reaches the VFS only by message (the host serves those frames). Worker platform executables preserve native-package protocols such as Landlock without replacing their JavaScript packages or coupling their implementations to `node:child_process`; ordinary commands use the package's evaluator and coreutils command table. The grammar is `@yarnpkg/parsers`' `parseShell`, while `execSync`/`fork` still refuse because they need a real process.
 - **`lib/client.js` (page half)** — startup has two independent stages. `chooseWorkerHostSource({ image?, fixtureManifest? })` optionally owns the boot barrier and fixture manifest: without `preview-fixture` it waits at the source chooser, while a valid query selects directly; either path returns ordered overlays. `connectWorkerHost(worker, { image?, overlays? })` remains the public base-runtime connector; callers that skip the chooser get an empty overlay list. `apps/web` invokes both and supplies its statically bundled Worker. The opening `init` frame carries the base and ordered overlay URLs, the boot payload delivers the structured index-injection table, and `applyIndexInjections` executes it before the shell entry runs. Script preload rows are advisory and skipped because `/plugins` resources resolve only through the tunnel; `loadBundle` fetches each combo on first demand, embeds its tunnel-only source map as a Base64 data URL, and executes the script as a Blob. The tunnel also exposes fetch-shaped transport, the independent file-upload carrier, and the API client. Request frames preserve Blob bodies through structured clone and transfer `ReadableStream<Uint8Array>` ownership. The Host Worker streams both forms into the route, so neither browser thread creates a complete byte array for a generic-file upload.

 一条 tsdown 管线出三个产物：
 
 - **`lib/index.js`（装配库）**——`createWorkerHost`/`startWorkerHost` 挂载基础镜像和按序排列的数据 overlays（`storage/`）、安装模块加载器（`module-system/`）与 `process` shim、经镜像自带的 `dsh-app-boot` 启动插件树，并把服务缝隙交给隧道。Overlay 只能替换 `home/` 与 `workspace/` 下的文件，不能替换基础 manifest、配置或模块。镜像布局契约（`image-layout.ts`：虚拟根、config/manifest 路径、空目录、`lowered` 包装契约门）与 packer 共享。boot patch 强制部署形态行：关前端静态服务、JSONL 会话日志走明文、preset 根指向镜像内 `config/agent-presets`。
-- **`lib/worker.js`（worker 束）**——装配库加本包的 Node 兼容层，合成一个自含 ES module。模块代理表（`module-proxies.ts`）是唯一平台叉口：`node:*` 内建走 VFS、隧道和浏览器原语，浏览器做不到的走结构化 stub（调用即在 console 报错并抛出），native/binary 包则替换执行后端。`node:module` 在镜像 package 根之上提供 `createRequire().resolve` 与 `.resolve.paths()`，使未修改的包无需执行目标模块即可发现 manifest。全局 `process` shim 带有包括 `title` 在内的 Node 环境识别字段，避免 Worker 执行误入仅适用于 DOM 的分支。pack 期解析器会把名称静态可知的模块请求报告给 packer 的可达性遍历，其中包括通过 `node:module` 或 `module` 具名导入在模块作用域直接发起的 `createRequire(import.meta.url)('pkg')` 调用。保存、经 CommonJS 获取或另设基准的 `createRequire` 调用需要镜像入口种子。VFS mutation 驱动 `node:fs` 的 callback、polling 和 promise watcher；打开的 descriptor 在 rename、replacement 和 unlink 后仍保留文件身份与访问模式；`readable-stream` 提供文件流以及 Chokidar、readdirp 等未修改镜像包所用的流状态机。AsyncLocalStorage 经 pack 时降低注入的 snapshot/restore 面在 `await` 间携带同步栈因果。worker 不带编译器：packer 未降低的镜像在挂载时被拒。

 - **`src/shell/`（worker 自己的进程层）**——浏览器 worker 无法 fork，所以 `node:child_process` 不是 stub 而是实现：`spawn` 把命令放进它自己的 Web Worker——就是这同一个束，由首帧告诉它「你是 shell 进程」——并以 subprocess 服务消费的 `ChildProcess` 面报告结果。命令不占宿主线程，`SIGKILL` 不管它在干什么都能终止它，而它只能靠消息触达 VFS（由宿主应答这些帧）。Worker 平台 executable 在不替换 JavaScript 包、也不把具体实现耦合进 `node:child_process` 的情况下保持 Landlock 等 native 包协议；普通命令使用本包的求值器与 coreutils 命令表。语法来自 `@yarnpkg/parsers` 的 `parseShell`，而 `execSync`/`fork` 依然拒绝，因为它们需要真进程。
 - **`lib/client.js`（页面半）**——启动分为相互独立的两段。`chooseWorkerHostSource({ image?, fixtureManifest? })` 可选地拥有 boot barrier 与 fixture manifest：没有 `preview-fixture` 时停在来源选择面板，合法 query 则直接选择；两条路径都返回按序排列的 overlays。`connectWorkerHost(worker, { image?, overlays? })` 仍是公开的基础运行态连接器；调用方跳过选择器时 overlay 列表为空。`apps/web` 调用这两段并提供静态打包的 Worker。开局 `init` 帧携带基础镜像与按序排列的 overlay URL，boot 载荷送达结构化 index 注入表，`applyIndexInjections` 在壳入口运行前逐行执行。脚本 preload 行只是提示，因此会被跳过：`/plugins` 资源只能经 tunnel 解析，`loadBundle` 会在首次需要时获取 combo、把仅 tunnel 可达的 sourcemap 内嵌为 Base64 data URL，再以 Blob 执行脚本。Tunnel 还暴露 fetch 形式的传输、独立文件上传载体和 API 客户端。请求帧通过结构化克隆保留 Blob 请求体，并转移 `ReadableStream<Uint8Array>` 的所有权。Host Worker 将两种请求体都逐块送入路由，因此通用文件上传不会在任何浏览器线程创建完整字节数组。

-`SessionWriteLease` (packages/session/session-persistence-jsonl/src/lease.ts) holds a kernel lock on `session.lock` beside the log for the whole life of a write handle: POSIX takes a non-blocking `flock(2)` through the prebuilt `@deepseek-ai/node-addon-system/flock` binding, and Windows holds a named kernel semaphore (count 1) derived from the canonical lock path (`CreateSemaphoreW` in src/win32.ts beside the existing koffi bindings) — a kernel object with no filesystem footprint, destroyed with its last handle. Contention maps to `SessionAlreadyOwnedError`; the kernel releases the lock when the holder's descriptor or handle closes, including on any process death, so a crashed holder never blocks a successor and no expiry bookkeeping exists. A live but wedged holder keeps the lock until its process exits: expropriating a stalled writer was rejected because its resumed appends would tear the log, and on POSIX removing the lock file remains the explicit forfeit for that case. Because a POSIX lock names an inode rather than a path, acquisition verifies the locked inode is still the file at the lock path and retries otherwise. The lock is taken at write-open of an existing artifact and, for a created session, only right before its first materializing write — an unmaterialized session leaves no filesystem footprint, and a handle that acquired the lock keeps it through close even when materialization fails; release never removes the lock file, preserving the stable inode later lockers verify against. The browser worker deployment stubs the flock entry to immediate success: it is single-process, so the in-process write claim already excludes every writer.

@@ -26,7 +26,7 @@ The browser worker host: the whole harness plugin tree runs inside one dedicated
 Three artifacts from one tsdown pipeline:
 
 - **`lib/index.js` (assembly library)** — `createWorkerHost`/`startWorkerHost` mount the base image and any ordered data overlays (`storage/`), install the module loader (`module-system/`) and the `process` shim, boot the tree through the image's own `dsh-app-boot`, and hand the tunnel its serving seams. Overlays may replace files only under `home/` and `workspace/`; they cannot replace the base manifest, configuration, or modules. The image layout contract (`image-layout.ts`: virtual root, config/manifest paths, empty directories, the `lowered` wrapper-contract gate) is shared with the packer. Boot patches force the deployment-shaped rows: frontend serving off, JSONL session logs on the plaintext path, preset roots onto the image's `config/agent-presets`.
-- **`lib/worker.js` (worker bundle)** — the assembly plus this package's Node-compatibility layer as one self-contained ES module. The module proxy table (`module-proxies.ts`) is the only platform fork: `node:*` builtins over VFS/tunnel/browser primitives, structural stubs that fail loud on the console for what a browser cannot do, and native/binary package replacements. `node:module` supplies `createRequire().resolve` and `.resolve.paths()` over the image package root, so unchanged packages can discover manifests without evaluating their modules. The global `process` shim carries Node detection fields including `title`, preventing Worker execution from entering DOM-only branches. The pack-time parser reports statically named module requests, including module-scope direct calls of the form `createRequire(import.meta.url)('pkg')` through a named `node:module` or `module` import, to the packer's reachability walk. Stored, CommonJS-obtained, and rebased `createRequire` calls require image entry seeds. VFS mutations drive `node:fs` callback, polling, and promise watchers; open descriptors retain file identity and access mode across rename, replacement, and unlink, and `FileHandle.stat({ bigint: true })` reports the same device and inode identity as a path stat while the name still refers to that file; `readable-stream` supplies the stream state machine used by file streams and unchanged image packages such as Chokidar and readdirp. AsyncLocalStorage carries sync-stack causality across `await` through the snapshot/restore faces the pack-time lowering injects. The worker holds no compiler: an image the packer did not lower is refused at mount.

The worker holds no compiler: an image the packer did not lower is refused at mount.
 - **`src/shell/` (the worker's own process layer)** — a browser worker cannot fork, so `node:child_process` is not a stub but an implementation: `spawn` starts the command in its own Web Worker — this same bundle, told by its first frame to be a shell process — and reports it through the `ChildProcess` surface the subprocess service consumes. The command runs off the host's thread, `SIGKILL` terminates it whatever it is doing, and it reaches the VFS only by message (the host serves those frames). Worker platform executables preserve native-package protocols such as Landlock without replacing their JavaScript packages or coupling their implementations to `node:child_process`; ordinary commands use the package's evaluator and coreutils command table. The grammar is `@yarnpkg/parsers`' `parseShell`, while `execSync`/`fork` still refuse because they need a real process.
 - **`lib/client.js` (page half)** — startup has two independent stages. `chooseWorkerHostSource({ image?, fixtureManifest? })` optionally owns the boot barrier and fixture manifest: without `preview-fixture` it waits at the source chooser, while a valid query selects directly; either path returns ordered overlays. `connectWorkerHost(worker, { image?, overlays? })` remains the public base-runtime connector; callers that skip the chooser get an empty overlay list. `apps/web` invokes both and supplies its statically bundled Worker. The opening `init` frame carries the base and ordered overlay URLs, the boot payload delivers the structured index-injection table, and `applyIndexInjections` executes it before the shell entry runs. Script preload rows are advisory and skipped because `/plugins` resources resolve only through the tunnel; `loadBundle` fetches each combo on first demand, embeds its tunnel-only source map as a Base64 data URL, and executes the script as a Blob. The tunnel also exposes fetch-shaped transport, the independent file-upload carrier, and the API client. Request frames preserve Blob bodies through structured clone and transfer `ReadableStream<Uint8Array>` ownership. The Host Worker streams both forms into the route, so neither browser thread creates a complete byte array for a generic-file upload.

 - **`src/shell/`（worker 自己的进程层）**——浏览器 worker 无法 fork，所以 `node:child_process` 不是 stub 而是实现：`spawn` 把命令放进它自己的 Web Worker——就是这同一个束，由首帧告诉它「你是 shell 进程」——并以 subprocess 服务消费的 `ChildProcess` 面报告结果。命令不占宿主线程，`SIGKILL` 不管它在干什么都能终止它，而它只能靠消息触达 VFS（由宿主应答这些帧）。Worker 平台 executable 在不替换 JavaScript 包、也不把具体实现耦合进 `node:child_process` 的情况下保持 Landlock 等 native 包协议；普通命令使用本包的求值器与 coreutils 命令表。语法来自 `@yarnpkg/parsers` 的 `parseShell`，而 `execSync`/`fork` 依然拒绝，因为它们需要真进程。
 - **`lib/client.js`（页面半）**——启动分为相互独立的两段。`chooseWorkerHostSource({ image?, fixtureManifest? })` 可选地拥有 boot barrier 与 fixture manifest：没有 `preview-fixture` 时停在来源选择面板，合法 query 则直接选择；两条路径都返回按序排列的 overlays。`connectWorkerHost(worker, { image?, overlays? })` 仍是公开的基础运行态连接器；调用方跳过选择器时 overlay 列表为空。`apps/web` 调用这两段并提供静态打包的 Worker。开局 `init` 帧携带基础镜像与按序排列的 overlay URL，boot 载荷送达结构化 index 注入表，`applyIndexInjections` 在壳入口运行前逐行执行。脚本 preload 行只是提示，因此会被跳过：`/plugins` 资源只能经 tunnel 解析，`loadBundle` 会在首次需要时获取 combo、把仅 tunnel 可达的 sourcemap 内嵌为 Base64 data URL，再以 Blob 执行脚本。Tunnel 还暴露 fetch 形式的传输、独立文件上传载体和 API 客户端。请求帧通过结构化克隆保留 Blob 请求体，并转移 `ReadableStream<Uint8Array>` 的所有权。Host Worker 将两种请求体都逐块送入路由，因此通用文件上传不会在任何浏览器线程创建完整字节数组。

 ## Problem
 
-Agent Teams needs the real Session log, subagent lifecycle, tools, examples, snapshots, and repository checks while its service and tool contracts continue to change. Placing those packages in a product-role group makes them members of the dsh release family and gives them the same publication expectation as stable packages.
+Agent Teams needs the real Session log, subagent lifecycle, tools, examples, snapshots, and repository checks while its service and tool contracts continue to change. Users also need to install the complete Team composition from npm without building a source checkout.
 
-An experimental directory without a current package previously imposed placement, dependency, promotion, and release rules on no consumer. Agent Teams supplies the concrete consumer, but the directory needs mechanical release exclusion and dependency isolation rather than a documentation-only status.
+Moving the packages into product-role groups would remove their experimental names and imply stable-package ownership. Publishing every package under `packages/experimental/` would instead expose unrelated internal prototypes. The release policy needs an explicit Agent Teams exception while preserving the private default.
 
 ## Decision
 
-`packages/experimental/agent-team`, `packages/experimental/tool-agent-team`, `packages/experimental/agent-team-profile`, `packages/experimental/client-ui-agent-team`, and `packages/experimental/agent-team-web-profile` are private workspace packages. The [experimental package rules](../../../../packages/experimental/AGENTS.md) own 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`, `packages/experimental/agent-team-profile`, `packages/experimental/client-ui-agent-team`, and `packages/experimental/agent-team-web-profile` are public workspace packages. They retain their existing `@deepseek-ai/dsh-experimental-*` names and join the dsh release family. The [experimental package rules](../../../../packages/experimental/AGENTS.md) own the private default, this exception, and later promotion.
 
-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 dsh pack and publish set and the local baseline publisher include exactly these five experimental package directories. Workspace constraints require them to omit `private`, set `publishConfig.access` to `public`, and keep the experimental npm prefix. Every other experimental package remains private and excluded from publication by default. Release packages and apps outside the experimental group, plus the Python runtime, cannot name experimental packages in `dependencies`, `optionalDependencies`, or `peerDependencies`; experimental packages may depend on release packages and each other.
 
 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 Host-side Agent Teams profile bundle depends on the Team packages and applies after `dsh-base`. It inserts the Team rows and disables the global continuable-child controls whose model-visible names overlap the Team tools. The separate private Web profile applies after `dsh-web-app` and the Host profile; it inserts the Team UI, which mounts the Remote contribution generated by the Team package. Both layers leave the shipped base, CLI, Web, and Python runtime dependency graphs unchanged.
+The published Host-side Agent Teams profile bundle depends on the Team packages and applies after `dsh-base`. It inserts the Team rows and disables the global continuable-child controls whose model-visible names overlap the Team tools. The separate published Web profile applies after `dsh-web-app` and the Host profile; it inserts the Team UI, which mounts the Remote contribution generated by the Team package. Both layers remain opt-in and leave 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.
+Profile installation resolves each published bundle and its dependencies through the profile's package manager. The generic profile launcher then applies the selected layers without adding them to any shipped profile 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.
+Experimental status changes compatibility and support expectations, not publication for these five packages. They retain the repository's ordinary documentation, invariant, lifecycle, security, unit, real-composition, and snapshot requirements. Promotion still requires review of the public contracts, limitations, test evidence, runtime dependents, and a named owner accepting stable-package obligations.
 
 ## Alternatives considered
 
-**Keep Agent Teams in a product-role group and describe it as opt-in.** Opt-in composition controls model behavior but does not exclude packages from publication or prevent stable packages from taking runtime dependencies on them.
+**Move Agent Teams into product-role groups.** This would remove the requested experimental npm names and imply stable-package ownership before the contracts have stabilized.
 
-**Reserve an empty experimental group.** A directory without a current package has no owner or release mechanism to test. The group exists only while concrete packages need its enforced treatment.
+**Keep Agent Teams private and source-checkout only.** This preserves the simplest experimental policy but prevents users from installing the complete opt-in composition from npm.
+
+**Publish every experimental package.** Unrelated prototypes remain internal-only and have not accepted a public package contract.
 
 **Move the Subagent prerequisites into the experimental directory.** Child identity allocation and Activation teardown belong to the Subagent owner and contain no Team-specific contract. Moving or duplicating them would invert the dependency or split one lifecycle across packages.
 
 ## Consequences
 
-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.
+Agent Teams publishes as five installable tarballs in the dsh release family without changing package names or enabling Team in a shipped profile. Public availability does not make the packages stable or supported by default, and stable release packages cannot take runtime dependencies on them.
 
-The product-role grouping is less direct while the packages incubate. Promotion creates path and npm-name churn as specified by the experimental package rules.
+The release family carries explicitly named experimental exceptions. Promotion still creates path and npm-name churn as specified by the experimental package rules.

 ## 问题

+Agent Teams 的服务与工具约定仍在变化，但它需要使用真实 Session 日志、subagent 生命周期、工具、示例、快照和仓库检查。用户还需要直接从 npm 安装完整 Team 组合，而无需构建源码 checkout。
 
-没有实际包的 experimental 目录曾经让没有消费方的放置、依赖、promotion 和发布规则长期存在。Agent Teams 提供了具体消费方，但该目录需要机械强制的发布排除与依赖隔离，不能只用文档标记状态。
+把这些包移入产品职责组会移除实验性名称，并暗示稳定包 owner 已经就位。发布 `packages/experimental/` 下的所有包又会暴露无关的内部原型。发布策略需要为 Agent Teams 设置显式例外，同时保留默认私有原则。
 
 ## 决策
 
-`packages/experimental/agent-team`、`packages/experimental/tool-agent-team`、`packages/experimental/agent-team-profile`、`packages/experimental/client-ui-agent-team` 与 `packages/experimental/agent-team-web-profile` 是私有 workspace 包。[实验性包规则](../../../../packages/experimental/AGENTS.md)负责其 npm 名和 promotion 重命名；本记录负责其目录归属、发布排除与依赖隔离。

-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。
+dsh pack 与 publish 集合以及本地 baseline 发布器只会纳入这五个实验性包目录。workspace 约束要求它们省略 `private`、设置 `publishConfig.access` 为 `public`，并保留实验性 npm 前缀。其他实验性包默认仍为私有且不发布。实验组外的发布包与 app 以及 Python runtime 不得通过 `dependencies`、`optionalDependencies` 或 `peerDependencies` 引用实验性包；实验性包可以依赖发布包和其他实验性包。

+公开发布的 Host 侧 Agent Teams profile bundle 依赖 Team 包，并在 `dsh-base` 之后应用。它会插入 Team 配置行，并禁用模型可见名称与 Team 工具重叠的全局 continuable-child control。独立公开发布的 Web profile 在 `dsh-web-app` 与 Host profile 之后应用；它会插入 Team UI，后者挂载 Team package 生成的 Remote contribution。两个层都保持显式启用，不改变随附 base、CLI、Web 与 Python runtime 的依赖图。
 
-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。

 ## 曾考虑的替代方案
 
-**把 Agent Teams 留在产品职责组，并标为显式启用。** 显式启用的组合可以控制模型行为，但不会阻止包发布，也不能阻止稳定包对其建立运行时依赖。
+**把 Agent Teams 移入产品职责组。** 这会移除要求保留的实验性 npm 名称，并在约定稳定前暗示已有稳定包 owner。
 
-**预留空的 experimental 组。** 没有实际包的目录没有 owner，也没有可供测试的发布机制。只有具体包需要这套强制处理时，该组才存在。
+**让 Agent Teams 保持私有且仅供源码 checkout 使用。** 这会保留最简单的实验性策略，但用户无法从 npm 安装完整 opt-in 组合。
+
+**发布所有实验性包。** 其他原型仍只供内部使用，也没有接受公开包约定。
 
 **把 Subagent 前置能力移入 experimental 目录。** child 身份分配与 Activation teardown 属于 Subagent owner，且不包含 Team 专用约定。移动或复制这些能力会反转依赖方向，或把同一个生命周期拆到多个包中。
 
 ## 后果
 
-Agent Teams 可以使用完整仓库依赖图与质量检查，而不进入正式 tarball，也不会成为受支持的运行时依赖。在 Team 包 promotion 前，发布包不能暴露 Team，因此 CLI 实验会安装显式的私有 profile 层，而不是修改已发布 bundle。通用 profile launcher 可以接受该层，而不会让它的 plugin 依赖进入 dsh 发布闭包。
+Agent Teams 会作为 dsh 发布系列中的五个可安装 tarball 发布，同时保持包名不变，也不会在随附 profile 中启用 Team。公开可用不代表这些包稳定或默认受支持，稳定发布包也不能对其建立运行时依赖。
 
-孵化期间的产品职责分组不够直接。promotion 会按照实验性包规则产生路径和 npm 名改动。

+Agent Teams needs an explicit opt-in composition while its public contracts remain experimental. The default tool catalog and simple-task behavior must remain unchanged, while an explicitly requested Team must survive child Activation settlement and mailbox delivery races long enough for the Lead to aggregate the result before process teardown.
 
 ## Decision
 
 Every ordinary runtime root is the implicit Lead of a Team identified by that root's `SessionId`. The Team has no creation event: its Lead pseudo-row exists by identity, while durable state begins with the first member, message, or task event. A roster is flat and contains at most the configured number of immutable lowercase-kebab-case names. Each teammate is a continuable direct child with a reserved Session id; only the Lead creates or interrupts teammates. Ordinary provider-owned subagents outside the roster are not Team members, and an ordinary fork is a new root whose inherited Team records are excluded by their ancestor `TeamId`.
 
-The implementation is split into `@deepseek-ai/dsh-experimental-agent-team`, which owns `ctx.agentTeams` and durable semantics, and `@deepseek-ai/dsh-experimental-tool-agent-team`, which owns scoped schemas and model guidance. Every Team tool declares its complete result schema and renders that value as compact JSON, so the compiler checks each `execute` against what the model is promised and no result spends tokens on indentation. Deployments mount both plugins explicitly and may disable legacy continuable controls with the same model-visible names. The explicit delegation policy permits Team creation only when the user asks for Agent Teams or teammates. Both packages are private members of `packages/experimental/`; the [experimental package decision](../architecture/2026-08-18-experimental-agent-teams-packages.md) owns release exclusion, dependency isolation, and promotion.

-- Every package here uses the `@deepseek-ai/dsh-experimental-*` npm prefix, sets `private: true`, and omits `publishConfig`; the workspace constraints gate enforces these declarations and the dsh release family excludes this directory.
-- Release packages and apps must not name packages here in `dependencies`, `optionalDependencies`, or `peerDependencies`. Experimental packages may depend on release packages and each other. Tests may use experimental packages through `devDependencies`; examples may load them explicitly.
+- Every package here uses the `@deepseek-ai/dsh-experimental-*` npm prefix.

+- Release packages and apps outside this group must not name experimental packages in `dependencies`, `optionalDependencies`, or `peerDependencies`. Experimental packages may depend on release packages and each other. Tests may use experimental packages through `devDependencies`; examples may load them explicitly.
 - Experimental status does not relax engineering, security, documentation, lifecycle, testing, invariant, or snapshot requirements.

 ## 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, the cross-realm Inspector, the CPython subprocess backend for the code-execution seam, and 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.
+The experimental group contains prototype capabilities whose contracts can change and carry no support promise.

 ## Summary
 
-`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.

It reads authoritative Team state through the generated `ctx.remote.agentTeams` contribution and keeps ordinary child-history navigation on the stable addressed-subagent path. Choose it for the experimental source-checkout Web profile; official releases exclude it.

 ## Summary
 
-This package lets the model create named teammates, send them messages, inspect availability, wait for progress, interrupt stuck work, and coordinate through a shared task board. Every team member receives the same nine tools and guidance for coordinating in a shared workspace. Choose it when the model should operate a team only after you explicitly request one. It replaces legacy subagent controls with the same tool names, so compositions that need both must disable the legacy definitions. The package is experimental, excluded from official releases, and provides no stability guarantee.

Subject: [PATCH 124/164] ci: add an opt-in canary value to the CI pool
 failover switches

The per-platform failover repository variables (DSH_CI_FAILOVER_LINUX and
DSH_CI_FAILOVER_WINDOWS) accept a third value alongside the existing
selfhosted routing. Set by a repository writer, the value retargets the
always-on pull-request and master lanes onto the matching hosted-runner
labels (16-core pools map to the 16-vCPU tier, standard legs to 4-vCPU);
unset or any other value keeps today's runners, so the leg is dormant until
a writer opts in - a canary path for capacity fallback, never the default.

Participating jobs: the three enterprise Linux workers, the node-compat
legs, the four Windows lanes, and the all-checks-passed verdict in ci.yml;
expected-filenames; the sandbox bwrap leg; and the two manual benchmark
matrices (4-32 vCPU tiers map to equivalents; 64/96-core rows keep the
fleet labels). Everything pinned to its own runner by spec, credential, or
host capability keeps it under every value, and the release-shaped chains
stay entirely hosted. request-review.yml was retired on master while this
work was in flight and the branch takes the deletion.

Specs pin the new branches: ci-workflow.spec.ts asserts the labels appear
in the extended selectors, and ci-compatible-selfhosted.spec.ts evaluates
the routing mode.

Subject: [PATCH 125/164] fix(scripts): enumerate repo files with a dirent
 walker instead of node fs.glob

Node's internal fs.glob, from some 24.x releases, lstat-probes
<matched>/<next segment> while expanding a ** pattern over a symlinked
file and throws ENOTDIR instead of skipping (observed on node 24.13.0
scanning snapshots/acp/image-compaction's symlinked
system-prompt.expected.md, which failed verify-md-wrap inside
check:ci:static). uniqueRepoFiles now walks with dirent types, never
probing a path under a file, and mirrors fs.glob's dot:false and
follow:false semantics: the four repo-files gate pattern sets enumerate
identically. Broken or cyclic symlinks fail loudly in the caller's
realpathSync, and pattern forms the walker does not model (metacharacters,
a trailing **, empty segments) are rejected up front. repo-files.spec.ts
pins the symlink, broken-link, and rejection behavior.

Subject: [PATCH 126/164] docs(ci): record the canary failover value and the
 glob fix across internal notes

The failover runbook, the node-compatibility note, the native-Windows note,
and the serial-reference note record the third variable value's scope and
exclusions (bilingual, pairing re-recorded); a new implemented process note
owns the value's participating set, the dormant-by-default canary posture,
and the walker-fix rationale. .github/AGENTS.md points at both notes.

Node compatibility jobs require a same-repository, non-fork head and a non-Dependabot author, use isolated runtime setup, and retain the `ubuntu-latest` fallback under unset and non-special values; the blacksmith branch carries none of those predicates.

 `ci-master.yml` exempts exactly one event from `cancel-in-progress` (`${{ github.event_name != 'push' }}`), so one master push does not cancel the drill still running from the previous one. Each drill runs its complete unsharded aggregate with one gate worker, which takes longer than the interval between master merges; under unconditional cancellation a drill is superseded before reaching a verdict and the lane yields no readiness evidence for a responder to check.

In this repository's trust model that is not an escalation: the runner groups admit all workflows of this private, fork-disabled repository (a deliberate trade to make PR-ref failover possible at all), so any writer could already reach the VMs by pushing a branch workflow. The boundary against untrusted code is repository membership; the variables only route work for members.

 The master-only `windows` job in [ci-master.yml](../../../../.github/workflows/ci-master.yml) runs `windows node 24 / wine` on `ubuntu-latest`. It retains the checksum-verified Windows Node, Wine apt and pnpm caches, a hoisted install confined to a workspace snapshot, and the [shared Wine gate script](../../../../scripts/wine-windows-gates.sh) that runs the workspace build and production site. Node distribution transfers use bounded retries; when nodejs.org stalls on the large archive, a range-capable transport mirror resumes the same bytes, but nodejs.org remains the version and SHA-256 authority and the archive is never promoted before that checksum passes. Wine is outside the PR aggregate under the [master-only platform policy](2026-09-06-master-only-platform-ci.md). The [archived Wine experiment](../../archived/process/2026-07-27-wine-windows-gates-experiment.md) preserves its measured trade-offs, while this note owns the current dual topology.

 `windows-build` and `windows-native-tests` are dependencies of `all checks passed`; their workspace-build and targeted native-process results are blocking. `windows-coverage` remains an ordinary job but is absent from aggregate `needs`, so its 100%-per-file result stays red and visible without delaying the required verdict. `windows-observational` is also absent from aggregate `needs` and uses `continue-on-error` because Linux owns the blocking static, documentation, package, and built-artifact verdicts.

The standard hosted fallback remains available. These predicates constrain this job, not every workflow admitted to the pool. Both repository identity and fork status remain explicit to preserve its trust restriction if repository settings change; existing sibling selectors are outside this migration. The `blacksmith` failover value's branch drops those predicates: it targets ephemeral Blacksmith runners, so repository identity and fork status do not gate it (see the [blacksmith failover leg note](2026-09-09-blacksmith-failover-leg.md)).
 
 The temporary tool cache trades repeated Node downloads for isolation across concurrent runners and Node versions. A setup-node-only [ESM preload](../../../../scripts/ci-compatible-toolcache.mjs) assigns the cache inside the action process: the Actions runner overwrites reserved environment variables after reading step configuration. An executed path check rejects installations outside runner temp; compatibility processes do not inherit the preload. pnpm keeps its existing private setup destination and persistent content-addressed store. Compile caches and node-gyp headers use runner temp before the first pnpm invocation. No global Node symlink or system package changes are introduced. Hosted jobs retain their tool and package caching; self-hosted jobs do not restore or upload hosted package caches. The runner owns temporary-directory cleanup between jobs, and the shared image supplies native npm packages’ compiler and Python prerequisites.

+# Agent Note: Blacksmith as a failover leg for CI pools
+
+Status: implemented
+
+English | [中文](2026-09-09-blacksmith-failover-leg.zh.md)
+
+## Problem
+
+The [failover runbook](2026-07-26-ci-failover-runbook.md) routes degraded enterprise-pool traffic onto the in-house `vm-backup` and `dsh-win-ci` pools, which are proven but bounded standbys. Blacksmith sells GitHub-hosted-style runners on demand, and its migration wizard proposed replacing the repository's `runs-on` labels wholesale, which would put credential-holding, benchmark, and spec-pinned jobs on third-party infrastructure as the default. The wholesale replacement is not acceptable as a default: it breaks the workflow contract specs, distorts benchmark and performance-budget measurements, and moves trust-boundary jobs without a decision record.
+
+## Decision
+
+`DSH_CI_FAILOVER_LINUX` and `DSH_CI_FAILOVER_WINDOWS` additionally accept the value `blacksmith`. When any repository writer sets it, the platform's participating jobs retarget onto Blacksmith's hosted runners at the vCPU size matching the pool each job replaces; any other value (or unset) keeps today's runner, and `selfhosted` keeps routing to the in-house pools. Like the existing values this is writer-manageable repository state — no merge, re-run the affected jobs — and it costs money only while set, which is why it is an explicit outage or experiment choice, never the default.
+
+Participating jobs under `blacksmith`: the three enterprise Linux workers, the `node-compat` legs, the `all-checks-passed` verdict, and the four Windows lanes in [ci.yml](../../../../.github/workflows/ci.yml) (16-core pools map to `blacksmith-16vcpu-ubuntu-2404` and `blacksmith-16vcpu-windows-2025`, standard-hosted legs to `blacksmith-4vcpu-ubuntu-2404`); `expected-filenames`; the sandbox bwrap leg; and the two manual benchmark matrices, whose 4-32 vCPU tiers map to Blacksmith equivalents while the 64/96-core rows keep the fleet labels because Blacksmith offers no such tier. The blacksmith branches carry no Dependabot exclusion: Blacksmith runners are ephemeral, so the persistent-VM rationale that keeps Dependabot on the hosted pool does not apply. The python-runtime builder stays hosted in full: its PR and master callers (`ci.yml`'s and `ci-master.yml`'s `python-runtime` jobs) pass real-API credentials (`DEEPSEEK_API_KEY_EXTERNAL`) into the reusable workflow, its macOS and arm64 single-exe legs need GitHub's images, and its wheel output feeds the PyPI publication chain. The docs-pages workflow is a tag-dispatched release publication, so it stays hosted too.
+
+Everything else keeps its own runner under every value: jobs pinned to standard hosted runners by workflow spec (`node-24-bench`, `python-sdk`, the master Wine gate, `release-publish` and `release-vendor-publish`, the Cloudflare preview, the weighted-approval pair); jobs that hold credentials (the real-API e2e lanes, the issue App-token jobs, the npm and PyPI publishers); jobs that need a host capability Blacksmith lacks (the Landlock legs and their pack verification, the Seatbelt leg, the linux-arm64 single-exe leg); and the release-shaped chains — the npm publishers, the PyPI publishers, the node-addon-system release chain, and the Pages deployment workflow — which stay entirely hosted because their artifacts feed published registry output. The release rehearsal jobs in `release.yml` and `release-vendor.yml` (`dependencies`, `pack`) keep their existing pre-change routing unchanged: they carry only the pre-existing `selfhosted` branch, so under `blacksmith` they fall back to their hosted `ubuntu-24.04` default exactly as under an unset variable, and they gain no `blacksmith` branch.
+
+## Alternatives considered
+
+Adopting the migration wizard wholesale. Rejected because it breaks the workflow contract specs, changes benchmark semantics and performance-budget calibration, and moves credential-holding and trust-boundary jobs to third-party infrastructure as the default; the earlier wizard migration (closed PR #3053) was rejected for cost and the same review findings.
+
+Keeping the in-house pools as the only failover target. Rejected as the sole option because they are a bounded standby; Blacksmith adds elastic capacity for the outage and experiment cases where the fleet itself is the degraded resource.
+
+## Consequences
+
+The blacksmith legs stay dormant until the value is set, so they are exercised only during an actual failover or an explicit experiment. The mirror trial ([PR #3841](https://github.com/deepseek-harness/deepseek-harness/pull/3841), closed) ran the participating set hardcoded onto the Blacksmith labels and confirmed that `blacksmith-4vcpu-ubuntu-2404`, `blacksmith-16vcpu-ubuntu-2404`, and `blacksmith-16vcpu-windows-2025` schedule and execute. Blacksmith registers its runners as self-hosted, so under the `blacksmith` value the `node-compat` legs run their toolcache-isolation and isolated-installation verification steps (gated on `runner.environment == 'self-hosted'`) rather than skipping them; all three legs passed on the trial image ([run 34322356689](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34322356689)). The same trial surfaced one environment finding that this change fixes: while expanding `**`, node 24.13's internal `fs.glob` lstat-probes `<matched>/<next segment>` for a symlinked file and throws ENOTDIR instead of skipping ([run 34319926270](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34319926270)), failing `verify-md-wrap` inside `check:ci:static` on Blacksmith until [repo-files.ts](../../../../scripts/repo-files.ts) replaced `globSync` with a dirent walker; the fixed static lane is green on the same image. The trigger is the lstat-probe of a path beneath a matched symlink, not `**` over symlinked trees in general: the other `globSync` `**` call sites that scan symlink-bearing trees stayed green on the same run and needed no change. The benchmark matrices' 8 and 32 vCPU labels (ubuntu-2404 and windows-2025) were not part of the trial and are inferred by naming symmetry from the verified 4 and 16 vCPU labels; confirm with a manual dispatch before first use. The Landlock, Seatbelt, and linux-arm64 exclusions still rest on the prose dispatch measurements of the earlier migration attempt (closed PR #3053), recorded here as a known gap; the trial could not exercise those legs by design. Workflow specs pin the new branches — `ci-workflow.spec.ts` asserts the Blacksmith labels appear in the extended selectors, and `ci-compatible-selfhosted.spec.ts` evaluates the `blacksmith` routing mode — so a future rewrite of the selectors fails the unit gates. Default cost posture is unchanged: nothing runs on Blacksmith unless the variable says so.

+# Agent Note: Blacksmith 作为 CI 池的故障切换支路
+
+Status: implemented
+
+[English](2026-09-09-blacksmith-failover-leg.md) | 中文
+
+## 问题
+
+[故障切换手册](2026-07-26-ci-failover-runbook.zh.md)把降级的企业池流量路由到自有的 `vm-backup` 与 `dsh-win-ci` 池——它们是经过验证但容量有界的备用池。Blacksmith 按需出售类似 GitHub 托管的运行器，其迁移向导提议整体替换仓库的 `runs-on` 标签，这会把持有凭据、基准与 spec 钉死的作业默认放到第三方基础设施上。整体替换不适合作为默认：它会打破 workflow 契约 spec、扭曲基准与性能预算测量，并在没有决策记录的情况下搬动信任边界作业。
+
+## 决策
+
+`DSH_CI_FAILOVER_LINUX` 与 `DSH_CI_FAILOVER_WINDOWS` 额外接受值 `blacksmith`。任何仓库写者设置它时，该平台参与切换的作业按与被替换池匹配的 vCPU 档位重定向到 Blacksmith 托管运行器；任何其它值（或未设置）保持今天的运行器，`selfhosted` 继续路由到自有池。与既有取值一样，这是写者可管理的仓库状态——无需合并，重跑受影响的作业即可——并且只在设置期间产生费用，这正是它作为明确的故障或实验选择、而非默认的原因。
+
+`blacksmith` 下参与切换的作业：[ci.yml](../../../../.github/workflows/ci.yml) 中三个企业级 Linux 工作作业、`node-compat` 各腿、`all-checks-passed` 判定作业与四条 Windows 通道（16 核池映射到 `blacksmith-16vcpu-ubuntu-2404` 与 `blacksmith-16vcpu-windows-2025`，标准托管腿映射到 `blacksmith-4vcpu-ubuntu-2404`）；`expected-filenames`；sandbox 的 bwrap 腿；以及两个手动基准矩阵——其 4-32 vCPU 档位映射到 Blacksmith 等价档，64/96 核行保留自有池标签，因为 Blacksmith 没有对应档位。blacksmith 分支不带 Dependabot 排除：Blacksmith 运行器是临时的，因此把 Dependabot 留在托管池的持久虚拟机理由不适用。python-runtime 构建器整体保持托管：其 PR 与 master 调用方（`ci.yml` 与 `ci-master.yml` 的 `python-runtime` 作业）会把真实 API 凭据（`DEEPSEEK_API_KEY_EXTERNAL`）传入该可复用工作流，其 macOS 与 arm64 单文件分支需要 GitHub 镜像，且其 wheel 产物供给 PyPI 发布链。docs-pages 工作流是 tag 派发的发布，因此同样保持托管。
+
+其余作业在任何取值下都保留自己的运行器：被 workflow spec 钉死在标准托管运行器上的作业（`node-24-bench`、`python-sdk`、master 的 Wine 门禁、`release-publish` 与 `release-vendor-publish`、Cloudflare preview、weighted-approval 一对）；持有凭据的作业（真实 API 的 e2e 通道、issue App token 作业、npm 与 PyPI 发布作业）；需要 Blacksmith 缺失的宿主能力的作业（Landlock 各腿及其打包校验、Seatbelt 腿、linux-arm64 单文件分支）；以及发布形态的链——npm 发布、PyPI 发布、node-addon-system 发布链与 Pages 部署工作流——它们整体保持托管，因为其产物供给已发布的 registry 输出。`release.yml` 与 `release-vendor.yml` 中的发布演练作业（`dependencies`、`pack`）保持改动前既有的路由不变：它们只带既有的 `selfhosted` 分支，因此在 `blacksmith` 取值下与变量未设置时一样回落到托管的 `ubuntu-24.04` 默认，并不新增 `blacksmith` 分支。
+
+## 备选方案
+
+整体采纳迁移向导。否决，因为它打破 workflow 契约 spec、改变基准语义与性能预算校准，并默认把持有凭据与信任边界的作业搬到第三方基础设施；更早的向导迁移（已关闭的 PR #3053）因成本与同样的 review 结论被否决。
+
+只把自有池作为唯一故障切换目标。作为唯一选项被否决，因为它是容量有界的备用；Blacksmith 为「故障对象正是自有池本身」的故障与实验场景提供弹性容量。
+

 [Document Preview](../../../../packages/client/ui-sidebar-documentpreview/README.md) owns format selection and loading policy. Metadata registers with `ctx.documentPreviews`; components register separately into the keyed `sidebar.right.tab.document` Slot. Extension registrations precede builtins, then longer suffixes and registration order decide. The toolbar lists matching alternatives and remembers a manual choice per tab; plain text is the fallback. The child receives accumulated text or complete native bytes, the original resource address, and the standard `useResource` and `useTabInfo` hooks. Preview calls existing `read`, `readAll`, and `readRelated` through ordinary injection and decodes bytes in its own `rpc.ts`. Refresh remains per tab, with no resource reload, shared `changed` acknowledgement, extra resource wrapper, or content Session.
 
-Markdown and code reuse the incremental primitives with cumulative paged text. HTML and PDF read complete `Uint8Array<ArrayBuffer>` data; Host transport remains base64. Published buffers are borrowed read-only and never persist into layout or Session JSON. PDF.js runs in an owned Worker with version-matched bundled font and decoder data, and copies input before transfer to preserve Preview's retained buffer. HTML runs in a Blob iframe with `sandbox="allow-scripts"`, without same-origin, popup, form, download, or top-navigation privileges. The browser retains its normal external-network rules. Bounded static local JS/CSS reads stay in the parent; the opaque frame creates its own asset Blobs, because it cannot load parent-origin Blobs. Replacing the document replaces the browsing context and revokes its root Blob.

They retain intrinsic CSS-pixel dimensions; auto margins centre images smaller than the shared scroller, while larger dimensions extend its horizontal or vertical scroll range. The renderer provides no zoom or drag-to-pan. SVG markup never enters the application DOM or an iframe, so scripts remain inert and cannot reach the parent page. Replacing HTML or an image revokes its root Blob URL.

 **A local server, virtual host, or `file:` iframe.** These require extra hosting or filesystem authority. The preview is for static generated pages, not a complete application runtime; modules, dynamic filesystem requests, and arbitrary nested asset graphs are outside its support.
 
+**Sanitize SVG into the application DOM or an iframe.** A sanitizer would add a second SVG parser and an evolving active-content policy before placing untrusted markup in an interactive document. The `<img>` static-image context preserves native SVG rendering and intrinsic dimensions without giving the markup a script-capable DOM.

 ## Consequences
 
-Renderers can be replaced without changing the tab or file protocol. Full-file formats pay bounded whole-file memory and PDF adds bundled Worker/font/decoder bytes. Format selection and view state are page-local, not durable Session data. Preview owns RPC cancellation and native buffers independently of metadata observation. A tab retains its read version and the observation version captured at read start; refreshing it neither discards another tab's content nor clears its change notice. File reads remain non-transactional, and opaque versions are compared for equality, not ordering. The [recorded browser scenario](../../../../apps/web/tests/document-preview.e2e.ts) exercises the shared toolbar, incremental text, isolated HTML dependencies, and lazy continuous PDF Worker rendering.

A Chromium probe against the built app recorded the fill and scroll numbers (`.artifacts/sidebar-tab-types/app-probe.log`, `ROUND3`): a short file's preview is the pane body's content height, a long file scrolls inside the preview body, and the pane body never scrolls. The file tree's `tests/` cover ordering, lazy loading, collapse memory, reload, the three entry types, truncation and failure rows, and forget-on-abort. `apps/web/tests/sidebar-right.e2e.ts` opens a produced file from the conversation into the preview over the real Remote carrier.

 - The resource snapshot contains only `status`, `value`, and `failure`; `value` is `WorkspaceFileStat` metadata. Content reads do not wait for the first metadata frame once the provider is available. Observation failures take precedence over Preview's change notice; neither automatically replaces loaded content.
 - **Text pages** — plain text, Markdown, and code read through an inject callback to `remote.workspaceFiles.read(sessionId, path, { offset }, signal)`. The first mount reads page one; scrolling to the body end or **Load more** requests the next page until `eof`. The owner delivers the accumulated prefix as `{ kind: 'text', text, pages, eof }`, including source offsets and line counts. Markdown and code render that prefix incrementally; they do not render each page as a separate document. A newer-version page past page one restarts from the beginning rather than mixing versions. A failure before any content fills the body with the file-type icon, explanation, and retry; a later failure retains loaded content and adds the retry below it.
-- **Complete bytes** — PDF and HTML use an inject callback to `remote.workspaceFiles.readAll(sessionId, path, signal)`. `rpc.ts` decodes the wire base64 into `data: Uint8Array<ArrayBuffer>` for `{ kind: 'bytes', data }`. The Host's `maxFileBytes` cap rejects oversized files rather than truncating them. PDF copies retained bytes before worker transfer, keeping the Preview buffer usable. Bytes stay in transient view state, never persisted layouts or Session JSONL. Loading-mode changes retire previous results.

The Host's `maxFileBytes` cap rejects oversized files rather than truncating them. PDF copies retained bytes before worker transfer, keeping the Preview buffer usable. Bytes stay in transient view state, never persisted layouts or Session JSONL. Loading-mode changes retire previous results.
 - **Reload** — only the current Preview tab rereads through its Remote callbacks, preserving its scroll preference and retiring older requests. Its change notice compares the read version and the observation captured at read start with later `resource.value.version`; an already observed version does not become a new change after refresh. Reads neither refresh shared metadata nor clear another tab's notice.
 
 HTML runs in a Blob iframe with exactly `sandbox="allow-scripts"`, without `allow-same-origin`; scripts cannot access the parent application's origin or file reader. The renderer loads directly declared relative `.js` classic scripts and `.css` stylesheets through its ordinary inject callback to `remote.workspaceFiles.readRelated`, with fixed safety limits of 4 MiB per asset, 32 MiB total, and 64 distinct assets. Host code resolves the related path; `rpc.ts` decodes the returned bytes. Inside the renderer, base64 is used only to embed the iframe bootstrap payload in script text. A `<base href>` leaves dependency resolution to the browser, as do HTTPS resources. Local module imports, CSS `url()`/`@import`, and dynamic `fetch` do not use Host file access. Read failures, invalid UTF-8, or exceeded limits fail the preview rather than publishing a partial asset package. Replacing or unmounting the document releases its Blob URL.
 
+PNG, JPEG, GIF, WebP, BMP, ICO, and SVG render through Blob URLs in an `<img>` static-image context. The image keeps its intrinsic CSS-pixel dimensions; a smaller image centres in the shared scroller, and larger dimensions scroll on either axis. The renderer provides neither zoom nor drag-to-pan. SVG markup never enters the application DOM or an iframe, so its scripts cannot execute or reach the parent page. Replacing or unmounting the image revokes its Blob URL.
+
 Shared copy comes from `sidebarDocumentPreview`; each builtin renderer owns its localized labels.
 
-Initial reads, additional pages, and HTML/PDF preparation share a loading indicator that respects reduced-motion preferences. Loaded pages stay visible while another page loads. PDF pages form one vertical, width-fitted sequence and render lazily near the viewport. Code previews show source line numbers by default without including them in copied text; plain text uses the same font size and line height as code. Code sits on the pane's own background rather than the chat card's fill, and with wrap off both axes scroll in the shared document scroller while the copy banner stays pinned to the visible width.

 [`@deepseek-ai/dsh-package-manifest`](../../../../packages/util/package-manifest/README.md) owns `DshManifest` and its member declarations in one type-only file. The package belongs to the existing utility group and exports no runtime values. Author declarations and launcher-generated module fallback metadata are explicitly distinguished.
 
+Author metadata stays under `package.json.dsh`: optional `manifestVersion` identifies format `1`, `categories` carries free-form discovery tags, and `engines.dsh` declares compatible host versions as a SemVer range. Npm package identity and Node requirements retain their top-level fields. Categories are extensible tags rather than a closed role enum, so labels such as `skills` and `tools` do not constrain package composition.
+
 Readers import the shared declarations directly. Boot retains profile loading, raw JSON checks, defaults, and resolved runtime data. Client modules retain their normalized boot graph. The image packer resolves declared paths into directories. The Session catalog generator derives a read-only validated entry with a resolved import path; raw inputs and discovery rules remain local.
 
 App-boot declares a production dependency because its published declarations reference the shared types. Client modules, the private packer, and root scripts use development dependencies because their published APIs do not expose these types. Every package consumer has a TypeScript project reference. External authors import from the utility package; app-boot provides no compatibility re-exports.

 Authors gain one public import path at the cost of a published package and explicit dependency edges. Existing app-boot manifest type imports must use the new package. The [profile composition design](2026-08-05-profile-plugin-bundles.md) continues to own runtime semantics; type extraction does not change configuration acceptance or model-visible behavior.
 
 Compiler and packaged NodeNext consumer checks cover public imports. Existing profile, client, image configuration, and Session catalog tests cover reader behavior; documentation checks cover the utility classification and generated package catalogs. Optional declaration fields still require deliberate consumer updates when added.
+
+Manifest format and host compatibility declarations have no enforcement in current installers or loaders. The type-only package supplies neither a SemVer parser nor an installation policy; its README records that limitation so an author declaration is not mistaken for a compatibility check.

-# Agent Note: Content-sized diagram previews
-
-Status: implemented
-
-English | [中文](2026-09-09-content-sized-diagram-previews.zh.md)
-
-## Problem
-
-Short Graphviz and SVG images leave large empty regions when displayed inside 400px frames. A 59px Graphviz diagram occupies a 400px preview even though its rendered dimensions are already available to the browser.
-
-## Decision
-
-Mermaid, Graphviz, and SVG share the inert image canvas in `SourcePreview`. The browser derives its height from the image, preserves aspect ratio when shrinking to the available width, and adds 16px padding. Source switching retains the image and copying reads the original code. Theme changes regenerate Graphviz colors without introducing a separate sizing observer.
-
-This replaces the diagram-frame choice in [Static Markdown fence previews](../feature/2026-09-09-markdown-static-previews.md); that note continues to own HTML isolation, rendering lifecycle, and license obligations. HTML retains its opaque, script-free, 400px frame. SVG image mode disables scripts, link interaction, and external resource loading without inserting source-controlled markup into the application document.
-
-## Alternatives considered
-
-**Set iframe height to auto.** An iframe does not derive its outer height from its inner document. This still reserves an unrelated viewport.
-
-**Add a frame measurement script or same-origin access.** A diagram already has image dimensions. Extra execution or origin permissions and resize messaging are unnecessary for that content.
-
-## Consequences
-
-Short diagrams occupy only their rendered height and canvas padding. The browser geometry regression compares image and container height in light and dark modes, then verifies proportional scaling in a narrow viewport. Browser security checks include SVG scripts, event handlers, nested HTML, and external images; copy and source toggling remain covered. HTML automatic height remains outside this change because arbitrary document layout has different measurement and isolation requirements.

-# Agent Note: 按内容定高的图表预览
-
-Status: implemented
-
-[English](2026-09-09-content-sized-diagram-previews.md) | 中文
-
-## Problem
-
-较矮的 Graphviz 与 SVG 图片显示在 400px iframe 中时，会留下大块空白。浏览器已经知道图片的渲染尺寸，但一张 59px 高的 Graphviz 图表仍占据 400px 的预览区域。
-
-## Decision
-
-Mermaid、Graphviz 与 SVG 共享 `SourcePreview` 的不可执行图片画布。浏览器根据图片决定高度，在可用宽度不足时按比例缩小，并添加 16px 内边距。源码切换保留图片，复制读取原始代码。主题变化重新生成 Graphviz 配色，无需单独的尺寸观察器。
-
-这替代了[静态 Markdown fence 预览](../feature/2026-09-09-markdown-static-previews.zh.md)中的图表 iframe 选择；该记录继续维护 HTML 隔离、渲染生命周期与许可证义务。HTML 保留不透明来源、禁用脚本的 400px iframe。SVG 图片模式禁用脚本、链接交互与外部资源加载，无需把源码控制的标记插入应用文档。
-
-## Alternatives considered
-
-**把 iframe 高度设为 auto。** iframe 不会根据内部文档决定外部高度，仍然会保留与内容无关的视口。
-
-**添加 iframe 测量脚本或同源访问。** 图表已经具备图片尺寸，不需要额外执行权限、来源权限或尺寸消息协议。
-
-## Consequences
-
-较矮图表只占据渲染高度与画布内边距。浏览器几何回归用例在浅色和深色下比较图片与容器高度，再验证窄视口中的等比例缩放。浏览器安全检查包含 SVG 脚本、事件处理器、嵌套 HTML 与外部图片，并保留复制和源码切换覆盖。HTML 自动高度不属于本次改动，因为任意文档布局具有不同的测量与隔离要求。

-# Agent Note: Static Markdown fence previews
-
-Status: implemented
-
-English | [中文](2026-09-09-markdown-static-previews.zh.md)
-
-## Problem
-
-Readers need to see Mermaid and DOT diagrams, SVG artwork, and HTML examples directly in Assistant replies without interpreting source or copying it to another renderer. These sources are untrusted, and a renderer's npm license field may omit compiled components with separate distribution obligations.
-
-## Decision
-
-The shared Markdown renderer enables settled `mermaid`, `graphviz`/`dot`, `svg`, and `html` fences through localized `MarkdownLabels.preview` and the parsed fence language. The [UI primitives package](../../../../packages/client/ui-primitives/README.md) owns `SourcePreview`, which accepts a renderer, source, and labels without Session, file, or Cordis dependencies. Mermaid and Graphviz each supply a `.ts` renderer to that same component. Consumers without preview labels and streaming messages retain code.
-
-`CodeBlock.preview` owns default visualization, source switching, and verbatim copying. Previews omit the language banner and expose compact icon actions on hover or keyboard focus; devices with any touch input keep actions visible below the diagram. Switching to source hides the mounted preview, preserving completed rendering and pending work. Both views use the same focused toggle button, and copying always reads the source prop.
-
-`SourcePreview` owns loading, failure, and cancellation of stale result publication. Source replacement and unmounting cancel publication; cancellation before runtime loading completes skips layout. Failures show a localized error and the original source, and replacing invalid source with valid input recovers the preview.
-
-Mermaid loads on demand. A shared queue serializes theme initialization with diagram work, and each call removes its temporary measurement DOM in `finally`. Strict security, disabled HTML labels, the application palette, and error-rendering policy cannot be overridden by diagram configuration. Generated SVG is displayed as an image without installing links or scripts. Intrinsic dimensions come from the SVG viewBox; large diagrams shrink to fit, and the canvas follows the code-block background. Mounted previews observe document theme attributes and regenerate only when resolved colors change; obsolete renders cannot publish. Graphviz default colors follow the same palette, while authored DOT, SVG, and HTML colors remain intact.
-
-HTML uses DOMPurify with navigation attributes and document-loading elements forbidden, followed by an opaque `sandbox=""` iframe. A trusted CSP precedes source markup and permits only inline CSS, data images, and data fonts. Scripts, external resources, child frames, form submission, and same-origin access are unavailable. SVG is parsed as XML and displayed with Graphviz output as inert images in a [content-sized canvas](../bug-fix/2026-09-09-content-sized-diagram-previews.md), so SVG scripts and links never become active. HTML frames have a fixed scrollable viewport: measuring their content would require additional origin access or trusted frame scripts.
-
-Graphviz uses the pinned, unmodified `@viz-js/viz` 3.30.0 WebAssembly distribution with the `dot` layout engine. Its npm MIT declaration covers the wrapper; its build provenance identifies Graphviz 16.0.0 (EPL-2.0), Expat 2.8.4 (MIT), and Emscripten 5.0.7 (MIT/NCSA). Distribution retains these component terms and the exact Graphviz source download under EPL-2.0 section 3.1. [Full preview notices](../../../../packages/client/ui-primitives/THIRD_PARTY_PREVIEW_NOTICES.txt) also retain Mermaid's MIT text and select Apache-2.0 for DOMPurify. The UI primitives package ships the notices and the Web build emits the same bytes alongside its assets. License review covers embedded payloads separately from the general permissive npm-metadata policy.
-
-## Alternatives considered
-
-**Keep the code banner above diagrams.** A language label and permanent text controls distract from the diagram. Overlay actions retain source access without reserving a title row.
-
-**Render each streamed chunk.** Incomplete diagrams are frequently invalid, and repeated layout work competes with text streaming. Message settlement provides complete source.
-
-**Put rendering inside Chat or add a general preview registry.** A shared primitive with plain props satisfies reuse without another registry or feature-plugin dependency. This follows the [shared-control rule](../architecture/2026-09-05-shared-client-control-primitives.md).
-
-**Execute HTML scripts in a frame.** Static chat examples do not need script execution. An empty sandbox plus sanitization and CSP gives the preview fewer capabilities and avoids introducing a frame messaging protocol.
-
-**Insert rendered markup into Chat.** The requested preview needs diagram display and source access; HTML styles and executable SVG would share the application document. Iframes isolate layout and origin; SVG image mode additionally disables SVG behavior.
-
-**Treat Viz.js as MIT-only or use a remote Graphviz service.** The compiled Graphviz license still applies locally; a remote renderer would send conversation content off-device. The bundled renderer retains source availability and legal notices without network rendering.
-
-## Consequences
-
-The feature changes presentation without changing persisted messages, provider requests, tools, or Host APIs. Inline HTML styles work, while interactive scripts, external assets, and links do not. Mermaid and Graphviz add lazy browser assets and run layout on the browser thread. Cancellation cannot preempt active layout; Mermaid finishes and releases its measurement DOM even when its result cannot be published. The previews have no editing, export, zoom controls, or interactive diagram links.
-
-Component tests cover source copying, default preview, delayed completion, stale success and failure, unmounting, fallback, cancellation, runtime loading failure, and recovery. The keyless [browser scenario](../../../../apps/web/tests/markdown-mermaid.e2e.ts) verifies Chinese Mermaid flowcharts, sequence diagrams, malformed source, configuration overrides, opaque frames, real image decoding, source toggling, blocked script/navigation/resource attempts, English/Chinese UI snapshots, and served license text. Notices checks pin the reviewed wrapper and native provenance so upgrades require renewed review.

-# Agent Note: 静态 Markdown fence 预览
-
-Status: implemented
-
-[English](2026-09-09-markdown-static-previews.md) | 中文
-
-## Problem
-
-读者需要直接在 Assistant 回复中查看 Mermaid 和 DOT 图表、SVG 图像和 HTML 示例，而不必解读源码或复制到其他渲染器。这些源码不可信，而渲染器的 npm 许可证字段可能遗漏编译组件各自的分发义务。
-
-## Decision
-
-共享 Markdown 渲染器通过本地化的 `MarkdownLabels.preview` 和解析后的 fence 语言启用定稿后的 `mermaid`、`graphviz`/`dot`、`svg` 和 `html` fence。[UI primitives 包](../../../../packages/client/ui-primitives/README.zh.md)拥有 `SourcePreview`，它接收渲染器、源码和文案，不依赖 Session、文件或 Cordis。Mermaid 与 Graphviz 各自向同一组件提供 `.ts` 渲染器。未提供预览文案的调用方与流式消息保留代码显示。
-
-`CodeBlock.preview` 负责默认可视化、源码切换与原样复制。预览省略语言横幅，在悬停或键盘聚焦时显示紧凑的图标操作；具有任何触控输入的设备始终在图表下方显示操作。切换到源码会隐藏已挂载的预览，保留完成的渲染和待完成的工作。两种视图使用同一个保持焦点的切换按钮，复制始终读取源码属性。
-
-`SourcePreview` 负责加载、失败和取消过期结果发布。替换源码和卸载组件会取消结果发布；在运行时加载完成前取消会跳过布局。失败时显示本地化错误与原始源码，用有效输入替换无效源码后可以恢复预览。
-
-Mermaid 按需加载。共享队列将主题初始化与图表渲染一起串行执行，每次调用都在 `finally` 中删除临时测量 DOM。图表配置无法覆盖严格安全模式、禁用 HTML 标签、应用配色和错误渲染策略。生成的 SVG 作为图片显示，不安装链接或脚本。固有尺寸来自 SVG viewBox；大图缩小以适应宽度，画布使用代码块背景。已挂载的预览观察文档主题属性，仅在解析后的配色变化时重新生成；过期渲染不能发布结果。Graphviz 的默认颜色采用同一配色，DOT、SVG 和 HTML 中明确指定的颜色保持原样。
-
-HTML 先由 DOMPurify 清理，禁止导航属性与文档加载元素，再进入不透明来源的 `sandbox=""` iframe。可信 CSP 位于源码标记之前，仅允许内联 CSS、data 图片与 data 字体。脚本、外部资源、子 iframe、表单提交与同源访问均不可用。SVG 按 XML 解析后，与 Graphviz 输出一同作为不可执行图片显示在[按内容定高的画布](../bug-fix/2026-09-09-content-sized-diagram-previews.zh.md)中，因此 SVG 脚本与链接不会激活。HTML iframe 使用固定的可滚动视口：测量内容需要额外的来源访问权限或可信 iframe 脚本。
-
-Graphviz 使用固定且未修改的 `@viz-js/viz` 3.30.0 WebAssembly 发布包，布局引擎为 `dot`。其 npm MIT 声明覆盖包装层；构建来源记录标明 Graphviz 16.0.0（EPL-2.0）、Expat 2.8.4（MIT）与 Emscripten 5.0.7（MIT/NCSA）。分发保留各组件条款，并按 EPL-2.0 第 3.1 节提供准确的 Graphviz 源码下载地址。[完整预览声明](../../../../packages/client/ui-primitives/THIRD_PARTY_PREVIEW_NOTICES.txt)还保留 Mermaid 的 MIT 文本，并为 DOMPurify 选择 Apache-2.0。UI primitives 包携带该声明，Web 构建在资源旁输出相同字节。内嵌产物的许可证检查独立于通用的宽松 npm 元数据策略。
-
-## Alternatives considered
-
-**在图表上方保留代码横幅。** 语言标签和常驻文字控件会分散对图表的注意力。浮层操作保留源码访问，不占用标题行。
-
-**渲染每个流式片段。** 未完成的图表通常无效，反复布局会与文本流式输出争用资源。消息定稿可提供完整源码。
-
-**在 Chat 内部渲染，或添加通用预览注册表。** 使用普通属性的共享基础组件即可满足复用，无需另加注册表或功能插件依赖。这遵循[共享控件规则](../architecture/2026-09-05-shared-client-control-primitives.zh.md)。
-
-**在 iframe 内执行 HTML 脚本。** 静态聊天示例不需要脚本执行。空 sandbox、清理与 CSP 降低预览权限，也避免引入 iframe 消息协议。
-
-**把渲染标记插入 Chat。** 所需预览只需显示图表和访问源码；HTML 样式和可执行 SVG 会与应用共享文档。iframe 隔离布局与来源，SVG 图片模式额外禁用 SVG 行为。
-
-**将 Viz.js 视为仅使用 MIT，或使用远程 Graphviz 服务。** 本地编译的 Graphviz 仍受其许可证约束；远程渲染会把对话内容发送到设备之外。内置渲染器保留源码可获取性与法律声明，无需网络渲染。
-
-## Consequences
-
-该功能改变呈现，不改变持久化消息、provider 请求、工具或 Host API。HTML 内联样式可用，交互脚本、外部资源和链接不可用。Mermaid 和 Graphviz 增加按需加载的浏览器资源，并在浏览器线程上执行布局。取消无法抢占进行中的布局；即使结果无法发布，Mermaid 仍会完成并释放测量 DOM。预览不提供编辑、导出、缩放控件或交互式图表链接。
-
-组件测试覆盖源码复制、默认预览、延迟完成、过期成功与失败、卸载、回退、取消、运行时加载失败与恢复。无密钥[浏览器场景](../../../../apps/web/tests/markdown-mermaid.e2e.ts)验证中文 Mermaid 流程图、时序图、无效源码、配置覆盖、不透明来源 iframe、真实图片解码、源码切换、脚本／导航／资源请求被阻止、中英文 UI 快照和已提供的许可证文本。声明检查固定已审查的包装层与原生构建来源，升级时须重新审查。

-The Markdown preview distribution also contains Graphviz 16.0.0 (EPL-2.0), Expat 2.8.4 (MIT), and Emscripten 5.0.7 runtime code (MIT/NCSA) inside `@viz-js/viz` 3.30.0. The wrapper's MIT metadata does not relicense these components. [Preview notices](packages/client/ui-primitives/THIRD_PARTY_PREVIEW_NOTICES.txt) preserve their full license texts and Graphviz source availability, together with Mermaid's MIT and DOMPurify's selected Apache-2.0 terms. The UI primitives npm package includes this file; the Web build emits it as `preview-third-party-notices.txt`.

 Each nonempty appended `system/message` owns a collapsed prompt row, including a complete prompt at the start of a headerless window; the same-step header does not duplicate it. Chat also shows a collapsed `System prompt` row for a non-empty initial request, explicit message-series start, or `system/message` surface node replacement whose text differs, reading the last nonempty surviving system node in surface order at the `request/header`; a non-initial request whose preceding header is outside the loaded history window also shows one. A resume repeats the row even when its system text is unchanged, including after pagination supplies the preceding header and system node; same-series config-only or tool-only changes, tool steps, and retries create no repetition, and a `system/message` event is never rendered as a transcript message. 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 request whose system node is empty or outside the loaded window creates no row until the page holding the node arrives.

-## Mermaid previews
-
-Settled Assistant Markdown shows `mermaid` code fences as diagrams. Diagrams have no language banner. Source/Preview and Copy icon actions appear on hover or keyboard focus and remain visible on touch devices; both views copy the original Mermaid source. Streaming fences remain code until the message settles; invalid diagrams show an error and their source without disrupting other blocks. Chat enables the shared [Mermaid preview primitive](../ui-primitives/README.md) through localized labels. Chat also previews `graphviz`/`dot`, `svg`, and static `html` fences in isolated iframes, with the same default visualization, source switching, and copying. HTML scripts, navigation, and remote resources are disabled. This is a presentation change and adds no model prompt, tool, or Session event.

 `MarkdownText` renders untrusted GFM and TeX math, blocks unsafe links and images, and can turn resolved file mentions into explicit controls. When the owner passes a `pathImages` vocabulary, image destinations that are local media paths rewrite to displayable URLs on settled renders only (the same streaming gate as file mentions); without a vocabulary, local destinations remain inert alt text. A load or decode failure replaces the image with its authored alt text, or the original destination when alt is empty. Changing the image source permits a fresh load. While a reply streams, it freezes completed blocks, advances a top-level open fence by completed lines, and highlights that fence from saved Shiki grammar state. Completed token lines enter fixed-size React groups, so later chunks reconcile only the growing group; an unchanged fence retains that DOM when the final full parse resolves cross-document syntax. `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 `projectUserText` projects sent user text into inline plain runs and reference chips for the message bubble and queue rows.
 
-Supply `MarkdownLabels.preview` to enable settled `mermaid`, `graphviz`/`dot`, `svg`, and `html` fences. Each language supplies localized preview states, and consumers without these labels retain code. Mermaid and Graphviz use the active document palette on the code-block background and update mounted previews when the theme changes. Explicit colors in DOT, SVG, and HTML remain authored content. Rendering loads Mermaid on demand, uses strict security, and exposes the generated SVG as an image with no diagram link handlers. A render failure shows the original source with the supplied error label; replacing the source discards late results from the previous render. The diagram keeps its intrinsic size and shrinks to fit the available width.
-
-`CodeBlock.preview` supplies an optional headerless body with icon actions for source switching and copying. Actions appear on hover or keyboard focus, and stay visible below the diagram whenever a touchscreen is available, including with a mouse attached. Switching to source keeps the preview mounted, so returning reuses its result; copying always retains the source.
-
-Each settled fence defaults to visualization and shares the source/copy controls. Graphviz loads `@viz-js/viz` on demand and renders DOT with the `dot` engine. SVG and Graphviz output are inert images in the same content-sized canvas as Mermaid; malformed SVG and DOT retain their source with an error. HTML accepts complete documents or fragments and preserves inline styles, but strips scripts and navigation. HTML frames have no sandbox permissions, and their Content Security Policy blocks external resources, embedded frames, forms, and scripts. Diagram canvases follow the rendered image height with 16px padding and shrink images proportionally to fit the available width. HTML frames use a 400px scrollable viewport. Raw HTML outside a code fence remains ordinary Markdown input.
-
-Internal render functions accept optional native `MermaidConfig` and Viz.js `RenderOptions` for developer customization. Attribute and theme-variable overrides merge with document defaults; Mermaid preview restrictions and Graphviz SVG output remain fixed. These parameters have no settings UI.
-
-[Preview license notices](THIRD_PARTY_PREVIEW_NOTICES.txt) ship with this package and the Web frontend. Mermaid is MIT; Viz.js is MIT but embeds Graphviz under EPL-2.0. The notices retain license texts and the exact Graphviz source download. Dependency upgrades require reviewing the embedded payload as well as npm metadata; the [preview decision](../../../.agents/notes/implemented/feature/2026-09-09-markdown-static-previews.md) records the distribution and sandbox choices.

-- **Diagram rendering runs on the browser thread** — every mounted settled preview starts rendering, including off-screen diagrams. Mermaid serializes layouts; Graphviz performs synchronous WebAssembly layout. Submitted layout work cannot be interrupted. Preview virtualization and worker rendering are not provided.
 - **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.
 - **A long highlighted fence retains its complete token DOM** — streaming avoids re-parsing, re-tokenizing, and reconciling the completed prefix, but it does not discard old colors or virtualize token spans. Final DOM cardinality therefore still follows the fence's token count; nested/container fences and a pathological single long line remain on the general tail path.
 - **Glyph-level icons are redrawn approximations** — the fish logo and the sparkle mark 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.

-
-    THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS ECLIPSE
-    PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION
-    OF THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
-
-1. DEFINITIONS
-
-"Contribution" means:
-
-  a) in the case of the initial Contributor, the initial content
-     Distributed under this Agreement, and
-
-  b) in the case of each subsequent Contributor:
-     i) changes to the Program, and
-     ii) additions to the Program;
-  where such changes and/or additions to the Program originate from
-  and are Distributed by that particular Contributor. A Contribution
-  "originates" from a Contributor if it was added to the Program by
-  such Contributor itself or anyone acting on such Contributor's behalf.
-  Contributions do not include changes or additions to the Program that
-  are not Modified Works.
-
-"Contributor" means any person or entity that Distributes the Program.
-
-"Licensed Patents" mean patent claims licensable by a Contributor which
-are necessarily infringed by the use or sale of its Contribution alone
-or when combined with the Program.
-
-"Program" means the Contributions Distributed in accordance with this
-Agreement.
-
-"Recipient" means anyone who receives the Program under this Agreement
-or any Secondary License (as applicable), including Contributors.
-
-"Derivative Works" shall mean any work, whether in Source Code or other
-form, that is based on (or derived from) the Program and for which the
-editorial revisions, annotations, elaborations, or other modifications
-represent, as a whole, an original work of authorship.
-
-"Modified Works" shall mean any work in Source Code or other form that
-results from an addition to, deletion from, or modification of the
-contents of the Program, including, for purposes of clarity any new file
-in Source Code form that contains any contents of the Program. Modified
-Works shall not include works that contain only declarations,
-interfaces, types, classes, structures, or files of the Program solely
-in each case in order to link to, bind by name, or subclass the Program
-or Modified Works thereof.
-
-"Distribute" means the acts of a) distributing or b) making available
-in any manner that enables the transfer of a copy.
-
-"Source Code" means the form of a Program preferred for making
-modifications, including but not limited to software source code,
-documentation source, and configuration files.
-
-"Secondary License" means either the GNU General Public License,
-Version 2.0, or any later versions of that license, including any
-exceptions or additional permissions as identified by the initial
-Contributor.
-
-2. GRANT OF RIGHTS
-
-  a) Subject to the terms of this Agreement, each Contributor hereby
-  grants Recipient a non-exclusive, worldwide, royalty-free copyright
-  license to reproduce, prepare Derivative Works of, publicly display,
-  publicly perform, Distribute and sublicense the Contribution of such
-  Contributor, if any, and such Derivative Works.
-
-  b) Subject to the terms of this Agreement, each Contributor hereby
-  grants Recipient a non-exclusive, worldwide, royalty-free patent
-  license under Licensed Patents to make, use, sell, offer to sell,
-  import and otherwise transfer the Contribution of such Contributor,
-  if any, in Source Code or other form. This patent license shall
-  apply to the combination of the Contribution and the Program if, at
-  the time the Contribution is added by the Contributor, such addition
-  of the Contribution causes such combination to be covered by the
-  Licensed Patents. The patent license shall not apply to any other
-  combinations which include the Contribution. No hardware per se is
-  licensed hereunder.
-
-  c) Recipient understands that although each Contributor grants the
-  licenses to its Contributions set forth herein, no assurances are
-  provided by any Contributor that the Program does not infringe the
-  patent or other intellectual property rights of any other entity.
-  Each Contributor disclaims any liability to Recipient for claims
-  brought by any other entity based on infringement of intellectual
-  property rights or otherwise. As a condition to exercising the
-  rights and licenses granted hereunder, each Recipient hereby
-  assumes sole responsibility to secure any other intellectual
-  property rights needed, if any. For example, if a third party
-  patent license is required to allow Recipient to Distribute the
-  Program, it is Recipient's responsibility to acquire that license
-  before distributing the Program.
-
-  d) Each Contributor represents that to its knowledge it has
-  sufficient copyright rights in its Contribution, if any, to grant
-  the copyright license set forth in this Agreement.
-
-  e) Notwithstanding the terms of any Secondary License, no
-  Contributor makes additional grants to any Recipient (other than
-  those set forth in this Agreement) as a result of such Recipient's
-  receipt of the Program under the terms of a Secondary License
-  (if permitted under the terms of Section 3).
-
-3. REQUIREMENTS
-
-3.1 If a Contributor Distributes the Program in any form, then:
-
-  a) the Program must also be made available as Source Code, in
-  accordance with section 3.2, and the Contributor must accompany
-  the Program with a statement that the Source Code for the Program
-  is available under this Agreement, and informs Recipients how to
-  obtain it in a reasonable manner on or through a medium customarily
-  used for software exchange; and
-
-  b) the Contributor may Distribute the Program under a license
-  different than this Agreement, provided that such license:
-     i) effectively disclaims on behalf of all other Contributors all
-     warranties and conditions, express and implied, including
-     warranties or conditions of title and non-infringement, and
-     implied warranties or conditions of merchantability and fitness
-     for a particular purpose;
-
-     ii) effectively excludes on behalf of all other Contributors all
-     liability for damages, including direct, indirect, special,
-     incidental and consequential damages, such as lost profits;
-
-     iii) does not attempt to limit or alter the recipients' rights
-     in the Source Code under section 3.2; and
-
-     iv) requires any subsequent distribution of the Program by any
-     party to be under a license that satisfies the requirements
-     of this section 3.
-
-3.2 When the Program is Distributed as Source Code:
-
-  a) it must be made available under this Agreement, or if the
-  Program (i) is combined with other material in a separate file or
-  files made available under a Secondary License, and (ii) the initial
-  Contributor attached to the Source Code the notice described in
-  Exhibit A of this Agreement, then the Program may be made available
-  under the terms of such Secondary Licenses, and
-
-  b) a copy of this Agreement must be included with each copy of
-  the Program.
-
-3.3 Contributors may not remove or alter any copyright, patent,
-trademark, attribution notices, disclaimers of warranty, or limitations
-of liability ("notices") contained within the Program from any copy of
-the Program which they Distribute, provided that Contributors may add
-their own appropriate notices.
-
-4. COMMERCIAL DISTRIBUTION
-
-Commercial distributors of software may accept certain responsibilities
-with respect to end users, business partners and the like. While this
-license is intended to facilitate the commercial use of the Program,
-the Contributor who includes the Program in a commercial product
-offering should do so in a manner which does not create potential
-liability for other Contributors. Therefore, if a Contributor includes
-the Program in a commercial product offering, such Contributor
-("Commercial Contributor") hereby agrees to defend and indemnify every
-other Contributor ("Indemnified Contributor") against any losses,
-damages and costs (collectively "Losses") arising from claims, lawsuits
-and other legal actions brought by a third party against the Indemnified
-Contributor to the extent caused by the acts or omissions of such
-Commercial Contributor in connection with its distribution of the Program
-in a commercial product offering. The obligations in this section do not
-apply to any claims or Losses relating to any actual or alleged
-intellectual property infringement. In order to qualify, an Indemnified
-Contributor must: a) promptly notify the Commercial Contributor in
-writing of such claim, and b) allow the Commercial Contributor to control,
-and cooperate with the Commercial Contributor in, the defense and any
-related settlement negotiations. The Indemnified Contributor may
-participate in any such claim at its own expense.
-
-For example, a Contributor might include the Program in a commercial
-product offering, Product X. That Contributor is then a Commercial
-Contributor. If that Commercial Contributor then makes performance
-claims, or offers warranties related to Product X, those performance
-claims and warranties are such Commercial Contributor's responsibility
-alone. Under this section, the Commercial Contributor would have to
-defend claims against the other Contributors related to those performance
-claims and warranties, and if a court requires any other Contributor to
-pay any damages as a result, the Commercial Contributor must pay
-those damages.
-
-5. NO WARRANTY
-
-EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, AND TO THE EXTENT
-PERMITTED BY APPLICABLE LAW, THE PROGRAM IS PROVIDED ON AN "AS IS"
-BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR
-IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR CONDITIONS OF
-TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR
-PURPOSE. Each Recipient is solely responsible for determining the
-appropriateness of using and distributing the Program and assumes all
-risks associated with its exercise of rights under this Agreement,
-including but not limited to the risks and costs of program errors,
-compliance with applicable laws, damage to or loss of data, programs
-or equipment, and unavailability or interruption of operations.
-
-6. DISCLAIMER OF LIABILITY
-
-EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, AND TO THE EXTENT
-PERMITTED BY APPLICABLE LAW, NEITHER RECIPIENT NOR ANY CONTRIBUTORS
-SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL,
-EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST
-PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN
-CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE)
-ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE
-EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-7. GENERAL
-
-If any provision of this Agreement is invalid or unenforceable under
-applicable law, it shall not affect the validity or enforceability of
-the remainder of the terms of this Agreement, and without further
-action by the parties hereto, such provision shall be reformed to the
-minimum extent necessary to make such provision valid and enforceable.
-
-If Recipient institutes patent litigation against any entity
-(including a cross-claim or counterclaim in a lawsuit) alleging that the
-Program itself (excluding combinations of the Program with other software
-or hardware) infringes such Recipient's patent(s), then such Recipient's
-rights granted under Section 2(b) shall terminate as of the date such
-litigation is filed.
-
-All Recipient's rights under this Agreement shall terminate if it
-fails to comply with any of the material terms or conditions of this
-Agreement and does not cure such failure in a reasonable period of
-time after becoming aware of such noncompliance. If all Recipient's
-rights under this Agreement terminate, Recipient agrees to cease use
-and distribution of the Program as soon as reasonably practicable.
-However, Recipient's obligations under this Agreement and any licenses
-granted by Recipient relating to the Program shall continue and survive.
-
-Everyone is permitted to copy and distribute copies of this Agreement,
-but in order to avoid inconsistency the Agreement is copyrighted and
-may only be modified in the following manner. The Agreement Steward
-reserves the right to publish new versions (including revisions) of
-this Agreement from time to time. No one other than the Agreement
-Steward has the right to modify this Agreement. The Eclipse Foundation
-is the initial Agreement Steward. The Eclipse Foundation may assign the
-responsibility to serve as the Agreement Steward to a suitable separate
-entity. Each new version of the Agreement will be given a distinguishing
-version number. The Program (including Contributions) may always be
-Distributed subject to the version of the Agreement under which it was
-received. In addition, after a new version of the Agreement is published,
-Contributor may elect to Distribute the Program (including its
-Contributions) under the new version.
-
-Except as expressly stated in Sections 2(a) and 2(b) above, Recipient
-receives no rights or licenses to the intellectual property of any
-Contributor under this Agreement, whether expressly, by implication,
-estoppel or otherwise. All rights in the Program not expressly granted
-under this Agreement are reserved. Nothing in this Agreement is intended
-to be enforceable by any entity that is not a Contributor or Recipient.
-No third-party beneficiary rights are created under this Agreement.
-
-Exhibit A - Form of Secondary Licenses Notice
-
-"This Source Code may also be made available under the following
-Secondary Licenses when the conditions for such availability set forth
-in the Eclipse Public License, v. 2.0 are satisfied: {name license(s),
-version(s), and exceptions or additional permissions here}."
-
-  Simply including a copy of this Agreement, including this Exhibit A
-  is not sufficient to license the Source Code under Secondary Licenses.
-
-  If it is not possible or desirable to put the notice in a particular
-  file, then You may include the notice in a location (such as a LICENSE
-  file in a relevant directory) where a recipient would be likely to
-  look for such a notice.
-
-  You may add additional accurate notices of copyright ownership.

-
-      "Object" form shall mean any form resulting from mechanical
-      transformation or translation of a Source form, including but
-      not limited to compiled object code, generated documentation,
-      and conversions to other media types.
-
-      "Work" shall mean the work of authorship, whether in Source or
-      Object form, made available under the License, as indicated by a
-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain
-      separable from, or merely link (or bind by name) to the interfaces of,
-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions
-      to that Work or Derivative Works thereof, that is intentionally
-      submitted to Licensor for inclusion in the Work by the copyright owner
-      or by an individual or Legal Entity authorized to submit on behalf of
-      the copyright owner. For the purposes of this definition, "submitted"

-      designated in writing by the copyright owner as "Not a Contribution."
-
-      "Contributor" shall mean Licensor and any individual or Legal Entity
-      on behalf of whom a Contribution has been received by Licensor and
-      subsequently incorporated within the Work.
-
-   2. Grant of Copyright License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-
-   END OF TERMS AND CONDITIONS
-
-   APPENDIX: How to apply the Apache License to your work.

 Bundle names resolve from the dsh installation first, then from the profile directory. In-box bundles (`@deepseek-ai/dsh-base`, `@deepseek-ai/dsh-web-app`, `@deepseek-ai/dsh-headless`, `@deepseek-ai/dsh-sdk-app`, `@deepseek-ai/dsh-sdk-minimal`, `@deepseek-ai/dsh-acp-app`) therefore always come from the same installation as the running `dsh`; out-of-tree bundles come from the profile's pnpm-managed `node_modules`. A bare plugin `name` in any patch row resolves through the profile directory's Node parent walk, which reaches the maintained installation fallback `$DSH_HOME/profiles/node_modules`. Plain Node installations place one healed symlink there per dependency-closure package. A pkg executable instead places a real ESM proxy that mirrors explicit exports and re-exports the virtual package URL, because operating-system symlinks cannot enter pkg's `/snapshot` filesystem. Every launch also links packages carried only by selected external bundles through a dsh-owned directory into the current profile's `node_modules`; existing pnpm entries win, and each profile owns its links independently.

 `dsh --profile <name> --from-default-profile <template>` initializes a new custom target from one of those five shipped templates before boot. The target name cannot be a shipped profile name, and its complete profile directory must not exist. The launcher claims that directory exclusively, so residual files and another concurrent creator are rejected without modification. It copies the template's current bundle list and `patchReload` value into a new manifest with empty dependencies and an empty user patch. It does not read the local profile named by `<template>`, copy its dependencies or patch, or persist an inheritance field; later template-list changes do not rewrite the new profile. The in-box bundles named by that copied list still resolve from the current dsh installation. A successful initialization adds no launcher output.

 A one-shot task (`dsh --profile headless "run the tests"`) creates one fresh persisted Agent through the core registry, submits the task, waits for quiescence, and flushes the Session before deriving the last non-empty assistant text and final `turn/end` reason from its durable interval. It streams non-empty provider reasoning deltas to stderr under a `dsh: reasoning:` heading, prints only the final text on stdout, and exits 0 for `completed`, else 1; a successful response with no reasoning leaves stderr empty. An invocation with no task is a usage error from that app. The shipped headless profile mounts no browser Connection, HTTP server, Web runtime, or browser client, and opens no listening port.

 The base bundle mounts the native DeepSeek adapter, settings and credential providers, stable `web_search` and `web_fetch`, the public-only HTTP fetch provider, opt-in DeepSeek session-log upload, and feedback-gated OTel upload for all users. 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`. Enabled fetch calls run in every sandbox and approval mode without per-call confirmation; the provider rejects non-public destinations before connecting. The Web app disables the base tool row and exposes the same tools through its `cordis`, `ptc`, and `standard` agent presets.
 
-Feedback is recorded in the Session log without starting model work. Enable the [DeepSeek session-log contributor](../../../packages/session/session-log-deepseek/README.md) to send complete unaccepted log suffixes with subsequent DeepSeek requests, including configured gateways. [OTel session upload](../../../packages/session/session-telemetry-otel/README.md) applies to all users and providers, including `deepseek-official`, without requiring a request header. The base defaults to `FEEDBACK_ONLY`: new own text feedback, message ratings, edits, and withdrawals release the complete canonical prefix through that event, including stored context; later records wait for the next explicit feedback. Inherited parent feedback does not authorize a fork. Requests, restoration, mount, and HMR do not trigger capture. SDK batching may finish an authorized upload without further interaction or model work. `DSH_TELEMETRY_MODE=DISABLED` disables OTel delivery; `FULL` is rejected, and any non-empty `DSH_TELEMETRY_DISABLED` disables its row. `DSH_TELEMETRY_OTLP_URL` selects the collector. Handoff is best-effort, not collector acceptance; no durable outbox or retry guarantee is provided. These OTel settings do not enable or disable the DeepSeek contribution.

 Install external plugin bundles through `dsh plugin --profile <name> add <package-or-git-spec>`. The installed package owns its dependencies and contributes its declared `cordis.patch.yml` layer. The CLI also ships `@deepseek-ai/dsh-mcp-client` as a dependency for patch layers, but no MCP server is enabled by default because each server command is trusted executable code outside the agent sandbox.

 ## 安装归属
 
-Electron 拥有保留 profile `$DSH_HOME/profiles/desktop`。其 manifest 通过 `dsh.profile.bundles` 列出内置与已安装插件 bundle，`node_modules` 则同时包含精确版本的 `@deepseek-ai/dsh`、与之匹配的私有 `@deepseek-ai/dsh-desktop-host` 和所有桌面插件。把 Electron 专用进程入口与 overlay 放入私有应用包，可以避免 Desktop 实现成为公共 CLI 包的一部分。CLI 不能启动或修改该 profile。Electron 始终调用自身内置的 Node.js 与 pnpm，并把 store 固定在 `$DSH_HOME/desktop/pnpm/store`；它绝不使用系统 pnpm 或调用方的 npm/pnpm 配置。

 dsh 主渲染进程只获得桌面协议标记。独立插件窗口获得结构化的列出、安装、移除、更新和更新检查操作；两个渲染进程都拿不到文件系统、原始 Electron IPC、shell 或任意 pnpm 参数。
 
-Electron 根据应用 locale 选择类型化的中英文字典，并以英文作为 fallback。菜单、原生对话框与插件管理渲染进程使用同一 locale 数据；仓库的 Client UI i18n gate 会检查这些桌面源文件。

 ### Seed 安装
 
-安装包内的 seed 是安装工具包，不是可以直接运行的 `node_modules` 目录。打包过程会生成锁文件，在禁用生命周期脚本的情况下在线物化生产依赖图，删除 `node_modules` 以及所有临时 pnpm cache、config 和 state 目录，然后只使用最终 store 完成一次完整离线安装，并验证私有 Desktop Host 的入口与 overlay 均存在。macOS 构建随后从 pnpm 内容寻址 store staging 每个 Mach-O 对象，最多并发四个 Developer ID 签名进程，并且只在所有签名成功后才更新受影响的 SHA-512 索引记录。再一次离线安装会在分片前证明重写后的 store；准备过程随后解包最终归档，并验证每个内嵌签名。签名 seed 保留发布身份、本地第一方 tarball 及其描述文件、项目元数据、锁文件、完整性清单，以及在用户机器上重复该安装所需的 pnpm store 内容。

+One kind of Client import stands. `assembled-boot.ts` drives the shell itself, so it imports `AppWebEntry` from `@deepseek-ai/dsh-client-web` and the boot-manifest type from `@deepseek-ai/dsh-client-modules/client`: booting the real shell is what that harness is for, and both packages are already in the Host graph. The chat scenarios mirror `conversationContextKey` in `support.ts` instead of importing its Client owner.
 
 Nothing mechanically enforces this rule; keep it in review.

 ## Summary
 
-`dsh-acp` lets trusted programs automate persistent DeepSeek Harness agents through the standard [Agent Client Protocol](https://agentclientprotocol.com): create or resume sessions, select a model and reasoning effort, attach MCP servers, submit or cancel work, receive semantic updates, and close sessions independently. Choose it for out-of-process subagents, test runners, and scripted controllers; it intentionally omits DSH-specific presentation data and interactive UI features. Persistence supports listing, resuming, and closing sessions across process restarts, but deletion, forks, transcript replay, and additional directories are unsupported. Run `pnpm dsh --profile acp` to start the server; use `dsh-subagent-acp` as the repository client.

 每次调用时，`ctx.typertGateway.invoke()` 都会解析当前的描述符和 Cordis 服务，校验具名参数是否完全匹配，解析已注册的对象或 Context 身份标识，调用公开的业务方法，并校验其结果。业务服务继承 [`dsh-typert-protocol`](../../typert/protocol/README.zh.md) 的 `TypertRemoteService`，并用 `@Remote` 或 `@RemoteScope` 标记方法；已有其他基类时仍可改用 `bindTypertRemote()`。

-`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。

 ### 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.

 ### 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。

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".

 ### 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 Loader specifier and owning-tree base URL until restart, while the resolved manifest package name identifies the browser module. Distinct active Loader sources resolving to one package name are rejected; removing the conflict promotes the remaining source without requiring its fiber to restart. Bundle content changes reach the graph only through `rebuilt()` (the HMR hook).

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.

 ### 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。

 ### 显式交付
 
-Web 的 `standard`、`ptc` 与 `cordis` preset 提供 `present` 用于声明交付最终工作区文件，包括通过 Bash 创建的文件。创建文件后，以 `files: [{ path, description? }]` 调用。[present 工具](../../fs/tool-present/README.zh.md)拥有文件数量限制和 Session 声明。收尾 turn 显示响应式卡片，包含文件名称、类型、说明和在 Host 默认应用中打开源文件的按钮。匹配的行内代码引用打开相同源文件，不触发浏览器下载。同一路径重复声明时，选择收尾回复之前最近一次的说明。

 `present` 工具行显示正在交付、已交付、失败或中断状态；展开已结束的调用可查看其记录的结果。文件卡片展示全部交付文件。打开时，卡片显示进度、成功确认或可重试的错误。服务 Host 必须具备桌面和合适的默认应用；远程浏览器不会打开其所在设备上的应用。

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.

 ## 概述
 
-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。

+本插件在 root slot 中组合侧边栏、主内容和右栏。侧边栏宽度为 264～420px，默认为 280px，收起后保留 56px 控制栏；窗口宽度低于 1024px 时自动收起，打开右侧面板也会收起手动展开的侧边栏。右侧面板首次打开时使用视口宽度的 45%，之后保留用户的像素宽度偏好，上限为 70%。为给中栏保留 400px，框架先将右侧面板缩减至 300px，再报告空间不足，使占用方将其关闭，最后才进一步压缩中栏。拖动没有过渡延迟；右侧手柄在关闭或全屏时不显示。
 
 全局面板占据 root 作用域的 `main` keyed slot；`conversation` 是为会话界面保留的 key。`ctx.layout.selectPanel(id)` 选中已注册面板，`null` 则选中会话界面，但不改变当前会话。默认组合不注册任何全局面板。

-使用 `dsh-client-ui-primitives`，通过共享 React UI 构建 Web 客户端控件并渲染 agent 输出。它提供标准控件、图标、锚定浮层，以及用于带 TeX 公式的 Markdown、终端输出、文件读取、差异、搜索、网页检索和 JSON 的渲染器。这些渲染器会丢弃原始 HTML、限制链接并解析 ANSI 转义序列，以处理不受信任的模型输出。调用方必须提供本地化 label；这些组件仅依赖 React 和 `--dsw-*` 设计 token。

 tab 类型分两阶段注册，随包发布的引导类型走的正是别的包的类型走的同一条公开路径（`ui-sidebar-documentpreview` 是活的证明）。两个阶段都在类型自己的 `ctx.effect` 里，因此注册与创建它的插件同生共死。
 
 1. **类型**——`ctx.sidebarRightTabs.register({ id, kind, patterns?, priority?, canOpen?, title, guide? })`，一份没有运行时钩子的静态声明，返回 disposer。`id` 是这个实现在 tab 系统里的身份，在全部注册中唯一（包名是天然取值；随包引导页是 `@deepseek-ai/dsh-client-ui-sidebar-right/guide`）：一旦 extension 可以接管 builtin 的 kind，kind 就不再唯一，所以实现要自己命名，同一 `id` 的第二次注册会 throw。资源类型给出 `patterns`，即作用于 `dsh-resource://` 地址的 glob：含 `:` 的匹配整个地址（`dsh-resource://file/**`）；不含的匹配 URI 路径的任意深度且忽略大小写（`*.md`），不是 URI 的地址不匹配任何这类模式。页类型——引导页、文件树——不给出模式，按 kind 打开。`canOpen(address)` 否决一次命中。`title(address)` 是 tab chip 的文字，在 tab 打开时捕获。`guide` 列出引导页的入口框；选中一个即把贡献它的类型作为页打开。一个 `kind` 最多承载一份 `builtin` 与一份 `extension` 注册（extension 生效；它离开后 builtin 恢复）；kind 上的其它任何撞名都 throw。`id` 同时也是该类型正文与标题注册时用的 key，因此 extension 与它接管的 builtin 各占一个格位，席位渲染生效的那个。
-2. **正文**——`ctx.slots.register({ name: 'sidebar.right.pane.tab', key: definition.id }, Body)` 通过框架注入的 `useTabInfo()` 读取 `{ sidebar, panel, tab }`。`sidebar` 提供开合与全屏信息，`panel.id` 命名所在格，`tab` 包含原记录字段、`visible`、`navigation`、`signal` 和 `actions`。这些字段不再作为平铺owner props传入；类型自己的store仍使用 `useStore`/`actions`。可选标题注册及引导替换共享该hook；未注册标题时使用打开时保存的文本。

 ## 引导页
 
 默认页取决于已注册的引导入口数，不取决于 tab 类型数或已打开的 tab 数。恰好一个入口时直接打开对应页面（随包组合中为 Files）；没有入口或有多个入口时打开引导页。单入口生成的默认页在增加其他 tab 后仍不可关闭。任何格的最后一个 tab 也不可关闭；其他 tab 可以关闭。chip、上下文菜单与 `close` API 使用同一规则。显式添加引导页始终打开引导，即使只有一个入口。
 
-引导 tab 是一个居中标题、其下一行说明，以及各已注册类型贡献的每个 `guide` 条目一个入口框，按 `order` 排列。选中一个框会调用 `tab.actions.openTab(entry.kind, { replaceTab: true })`，于是引导页让位给它打开的页。一个格最多持有一个引导 tab。tab 条的添加控件只在该格没有引导 tab 时绘制，并以 `openTab('guide', { paneId, revealIfOpened: false })` 在该格打开一个，这样别的格里的引导页不会截走这次点击；把引导页开进已有引导页的格则改为聚焦它；把引导页拖入、放入或收回到这样的格会合并进去——来者关闭，该格自己的被聚焦；对引导页 `duplicateTab` 不记录任何东西。分栏或被清空的根格使用相同的默认页规则，每个新格一个 tab。普通的 `openTab('guide')` 保留每次打开都有的整树聚焦。产品最多保留左右两格，默认均分，分隔条限定20%～80%。宽度不足以容纳两格时不允许新分栏；已有两格时，正文拖放用于跨格移动，不再创建第三格。 达到两格上限时隐藏分栏控件；关闭回单格后恢复。

 ### 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。

 ## Summary
 
-Use this package to browse every subagent conversation beneath a parent session, open any descendant, and see whether it is running together with its token use and active-turn duration. Completed one-shot conversations open as read-only execution records. Continuable conversations accept follow-up prompts in submission order while they run and provide Stop independently. The ordinary session sidebar omits subagent conversations, so the parent header catalog is their navigation entry point. The separate `@` source inserts a running child's label into a user message without resolving it into a continuation address.

 ### 样式表
 
-`src/styles/` 下有六张样式表，由 ui-theme 的动态客户端 entry 依次导入：`base.css`、`corner-shape.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。`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。

 `corner-shape.css` 平滑所有圆角：在 `@supports (corner-shape: superellipse(1.5))` 内定义 `--dsw-corner-shape`，并通过通配选择器应用到所有元素及其 `::before`/`::after`，因此不支持 `corner-shape` 的引擎保持普通圆弧。正圆形状——`border-radius: 50%` 的圆与胶囊半径——因超级椭圆会使其变形，须在所属组件样式表中把 `corner-shape: round` 与半径声明配对；corner-shape 样式表 spec 跨全部包样式表强制这一配对。
 
-`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。它同时派生低一档变量 `--dsh-content-font-size-secondary`（设置 ≤14 时为设置值 −1，>14 时为设置值 −2；默认设置下为 13px）及配套的 `--dsh-content-font-delta-secondary`，供表格变体与比正文低一档的流内行使用。紧凑的小号文本与代码变体保持固定字号。阶梯之外，用户气泡与 composer 草稿直接读取正文档变量对，流内行的标题及摘要读取低一档变量对。该表还持有阴影阶（`--dsw-shadow-lv*`）与 elevation token：`--dsw-elevation-stroke` 经可重绑的 `--dsw-elevation-stroke-color` 画 0.5px 发丝描边，`--dsw-elevation-panel`/`--dsw-elevation-prominent`/`--dsw-elevation-soft`（输入框专用的更大模糊、更低透明度档）在描边之上叠两层极淡柔光，因此高层级表面设 `border: 0`，不再有占布局的轮廓；派生 token 逐元素重声明，使表面对描边色的重绑真实生效。

 ### 重排序与视图选项
 
-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。

-`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.

Its package-internal `ReactLoopInbox` constructor registers the standard `inbox` projection on the agent scope, then uses that projection for structural commands and loop-only claims. Registry reference counting keeps the shared key active until the last agent scope unloads. 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. The driver assembles the prompt and tools, projects runtime context, and runs `agent/pre-step`. A rejected decision or empty first batch opens no step. On the first attempt after acceptance, `step/start` precedes the `agent/request` waterfall and `prepareCall()`; neither async phase sees the pending system prompt or accepted users committed to history, and cancellation during either commits neither. For every attempt, the loop then synchronously reconciles the rendered prompt against the surviving `system/message` nodes using the prepared call capability, appends the accepted `user/message` batch only on the first attempt, logs the header and context as needed, and derives and freezes the request before streaming through that bound prepared call.

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.
 
 Prompt admission uses the actual `prepareCall()` result, not the preceding `request/context`. With no system node, even an empty prompt is appended (reserving node 0 without a wire message). On an incapable route or at a new request series, a non-empty rendering is consolidated at the first system node: each non-empty later system node receives a logged per-node empty replacement, then the head is rewritten if needed. Dormant empty tails need no replacement and do not determine the effective text. Consolidation applies even when the latest effective text is unchanged. On a continuing `in-history` series, an unchanged effective prompt produces no event and a non-empty change appends. An empty rendering clears every non-empty later system node through a logged per-node empty replacement, then empties the head if needed, regardless of route or series state. No older instructions remain model-visible. An empty head with no active later system node means no prompt; repeated clears and resume leave it empty. A restored non-empty prompt follows the same route/series rule: a continuing capable route may append it, while an incapable route or new series refills the head. A step starts a series when the pre-step decision declares `startsRequestSeries`, when the surface replace generation changed since attachment or the last request (compaction or any replacement), or when visible tool schemas changed. Resume and a provider or model swap alone continue the series; the prepared route still governs admission. Per-node empty replacements preserve intervening history without a surface delete operation.

-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；等待分别传入上下文与 Agent 的可选 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。创建运行时子 Agent 的调用方设置 `options.parentAgent`；调用方 Context 则单独拥有事务和存活 handle。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、关闭会话的写路径、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。

 提示词准入依据实际的 `prepareCall()` 结果，而非先前的 `request/context`。没有系统节点时，即使提示词为空也追加（预留第 0 号节点，但不产生协议消息）。在不具备能力的路由上或新请求序列开始时，非空渲染文本归并到首个系统节点：每个非空的后续系统节点分别收到有日志记录的空内容替换，随后按需重写头节点。未生效的空尾节点无需替换，也不决定有效文本。即使最新有效文本未变，也执行归并。延续中的 `in-history` 序列在有效提示词不变时不产生事件，非空变更则追加。无论路由或序列状态如何，空渲染文本都会通过有日志记录的逐节点空内容替换清除每个非空的后续系统节点，再按需清空头节点。模型不会继续看到旧指令。空头节点且没有生效的后续系统节点表示没有提示词；重复清除与恢复会话都保持为空。重新提供的非空提示词遵循同一路由／序列规则：延续中的具备能力路由可以追加它，不具备能力的路由或新序列则重新填充头节点。以下情况开启序列：pre-step 决定声明 `startsRequestSeries`、surface 替换 generation 自附接或上次请求以来发生变化（压缩或任何替换）、可见工具 schema 变化。恢复与单纯的提供方或模型切换都延续序列；准入仍由已准备的路由决定。逐节点的空内容替换保留其间历史，无需 surface 删除操作。

-只要身份、persona、变量、段文本与顺序的渲染完全相同，前缀就保持稳定：渲染未变时系统节点保持不动，除非不具备能力的路由或新请求序列必须归并保留的历史内提示词。没有 `systemPromptUpdate` 时，非空提示词文本通过有日志记录的逐节点替换归并到首个系统节点，因此头节点重写会从首个变化的 token 起失去前缀复用；当已准备调用声明 `systemPromptUpdate: 'in-history'` 时，agent loop（智能体循环）会在同一请求序列延续期间把变化后的非空提示词追加到已缓存历史之后，因此直到该历史末尾的前缀仍可复用（[决策规则](../agent-loop/README.zh.md#understand-the-implementation)）。 模型、persona 前缀、工具与前置指令一致时，不同源码路径、本地 Web URL 或 persona 后缀值不会改变可复用的第一方前缀。Persona 前缀变化可能改变靠前的前缀。任何变更都可能从第一个变化的 token 起使复用失效；不保证提供方共享缓存或实际命中率。

 ## Summary
 
-Use `dsh-tools` to expose typed capabilities to models, validate calls, enforce allow/deny/ask policy, and return finalized results without ending a turn on ordinary tool failures. Choose native function calling, [PTC mode](#ptc-mode), or both with `mode`; an agent can override the default through `presentAs`. Tool authors use `defineTool` to declare typed parameters and outputs, cooperative timeouts, parallel-safety, and optional UI presentation. Models see each permitted tool's declared name, description, and parameter schema; per-agent restrictions can narrow that visible set.

 ### 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。

 - **`lib/worker.js`（worker 束）**——装配库加本包的 Node 兼容层，合成一个自含 ES module。模块代理表（`module-proxies.ts`）是唯一平台叉口：`node:*` 内建走 VFS、隧道和浏览器原语，浏览器做不到的走结构化 stub（调用即在 console 报错并抛出），native/binary 包则替换执行后端。`node:module` 在镜像 package 根之上提供 `createRequire().resolve` 与 `.resolve.paths()`，使未修改的包无需执行目标模块即可发现 manifest。全局 `process` shim 带有包括 `title` 在内的 Node 环境识别字段，避免 Worker 执行误入仅适用于 DOM 的分支。pack 期解析器会把名称静态可知的模块请求报告给 packer 的可达性遍历，其中包括通过 `node:module` 或 `module` 具名导入在模块作用域直接发起的 `createRequire(import.meta.url)('pkg')` 调用。保存、经 CommonJS 获取或另设基准的 `createRequire` 调用需要镜像入口种子。VFS mutation 驱动 `node:fs` 的 callback、polling 和 promise watcher；打开的 descriptor 在 rename、replacement 和 unlink 后仍保留文件身份与访问模式；`readable-stream` 提供文件流以及 Chokidar、readdirp 等未修改镜像包所用的流状态机。AsyncLocalStorage 经 pack 时降低注入的 snapshot/restore 面在 `await` 间携带同步栈因果。worker 不带编译器：packer 未降低的镜像在挂载时被拒。
 - **`src/shell/`（worker 自己的进程层）**——浏览器 worker 无法 fork，所以 `node:child_process` 不是 stub 而是实现：`spawn` 把命令放进它自己的 Web Worker——就是这同一个束，由首帧告诉它「你是 shell 进程」——并以 subprocess 服务消费的 `ChildProcess` 面报告结果。命令不占宿主线程，`SIGKILL` 不管它在干什么都能终止它，而它只能靠消息触达 VFS（由宿主应答这些帧）。Worker 平台 executable 在不替换 JavaScript 包、也不把具体实现耦合进 `node:child_process` 的情况下保持 Landlock 等 native 包协议；普通命令使用本包的求值器与 coreutils 命令表。语法来自 `@yarnpkg/parsers` 的 `parseShell`，而 `execSync`/`fork` 依然拒绝，因为它们需要真进程。
 - **`lib/client.js`（页面半）**——启动分为相互独立的两段。`chooseWorkerHostSource({ image?, fixtureManifest? })` 可选地拥有 boot barrier 与 fixture manifest：没有 `preview-fixture` 时停在来源选择面板，合法 query 则直接选择；两条路径都返回按序排列的 overlays。`connectWorkerHost(worker, { image?, overlays? })` 仍是公开的基础运行态连接器；调用方跳过选择器时 overlay 列表为空。`apps/web` 调用这两段并提供静态打包的 Worker。开局 `init` 帧携带基础镜像与按序排列的 overlay URL，boot 载荷送达结构化 index 注入表，`applyIndexInjections` 在壳入口运行前逐行执行。脚本 preload 行只是提示，因此会被跳过：`/plugins` 资源只能经 tunnel 解析，`loadBundle` 会在首次需要时获取 combo、把仅 tunnel 可达的 sourcemap 内嵌为 Base64 data URL，再以 Blob 执行脚本。Tunnel 还暴露 fetch 形式的传输、独立文件上传载体和 API 客户端。请求帧通过结构化克隆保留 Blob 请求体，并转移 `ReadableStream<Uint8Array>` 的所有权。Host Worker 将两种请求体都逐块送入路由，因此通用文件上传不会在任何浏览器线程创建完整字节数组。

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.

 ## Summary
 
-The goal group lets one agent session pursue a durable completion objective across restarts, resumes, and forks. Agents can create and update the objective, while people can inspect or control it directly with `/goal` without spending a model turn. An optional continuation package can keep active work moving through sequential rounds. Each session has only one current goal, and that goal records completion state rather than scheduling work; automatic continuation must therefore be enabled separately.

-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。

 - **`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; stop is observe-only and cannot block the subagent or feed it context. Stop 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. 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`, `permission_mode`, and `effort` where Claude Code would provide them, and `transcript_path` is never populated: it is always the empty string, because the persistence seam exposes no artifact paths and the default-zstd session log is not readable by hook scripts. `systemMessage` is logged + warned but not surfaced; `{"continue": false}` is recorded but does not halt the run; `suppressOutput`, `stopReason`, and `terminalSequence` are not applied.

Matching handlers run serially and are not deduplicated, whereas Claude Code runs them in parallel and deduplicates identical handlers. One process-level `configPath` is parsed once at load; Claude Code's layered project, user, plugin, and policy discovery and live reload are not implemented.

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 picking Remote controller maps onto wire failure codes.

 ## 概述
 
-`interaction/` 组覆盖用户引导运行中 agent 的各种方式。斜杠命令适合无需模型往返的即时操作；一次性审批用于敏感操作；权限预设可以同时选择沙箱与审批行为；当 agent 需要信息或决定时，它还可以向用户提问。交互式应用向用户提供这些能力；自动化则通过 ACP 处理自己的审批。下方包映射说明了每项能力的区别，并链接其完整行为与配置。

 ## Summary
 
-`ask_user_question` lets a model pause work and ask the human for confirmation, a choice, or missing information. It accepts one or more questions and returns their answers as compact JSON. The call waits until an answer is accepted or the turn is cancelled; if no answer handler accepts it, the model receives an error. Runtime-owned child agents cannot call this tool and must report unresolved questions in their final result. The package does not render or collect input, so callers must provide a compatible user interaction surface.

 - **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。

 ### 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。

 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。

 ### Observation cache
 
-`observeSession` builds point observations without a listing preflight. A live observation fixes its cut as the current log length and materializes `events` on first read, so header-, cursor-, or projection-only consumers never copy the log; the log only appends, so a late first read still yields exactly that prefix. The cold path stats the stored session first and consults an own bounded cache keyed by the persistence instance and the `stat` revision: an unchanged revision reuses the restored unpublished Session without re-reading the log; a changed revision, or a replaced persistence instance, reloads through the handle seam and replaces the entry. The cache holds `preparedSessionCacheSize` entries with least-recently-used eviction, entries pinned by active observation leases are never evicted, and a session that goes live mid-read retries the live path.

 ### 观察缓存
 
-`observeSession` 不经过列表预检直接构建定点观察。实时观察以当前日志长度固定 cut，并在首次读取时才物化 `events`，因此只需要 header、cursor 或 projection 的消费者永远不会复制日志；日志只会追加，所以延后的首次读取得到的仍然正好是该前缀。冷路径先对存储会话执行 `stat`，再查询自有的有界缓存，缓存键为持久化实例加 `stat` 修订：修订未变则复用已恢复的未发布 Session，不再重读日志；修订变化或持久化实例被替换则经 handle 缝重新加载并替换条目。缓存保留 `preparedSessionCacheSize` 个条目并按最久未用淘汰，被活跃观察租约钉住的条目从不被淘汰；读取中途转为实时的会话会重试实时路径。

 ## Summary
 
-Use this package with a session persistence backend to make work durable before a model request, before a top-level tool can cause external effects, and before the next agent step begins. After each checkpoint, a crash can resume from stored requests, tool calls, responses, and results instead of losing them. Checkpoint failures are fail-closed: a model adapter or top-level tool body does not run until the durable write succeeds. The package has no configuration and adds no prompt or tool schema; unfinished Assistant streams remain transient, and interrupted tool calls recover with an unknown outcome instead of an automatic retry.

 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 complete lifecycle identity (`formatVersion`, `createdAt`, `cwd`, `isSeeded`, and `inheritedEventCount`), so a row folded from another Session format generation or fork cut cannot seed the caller. The JSON backend stores each record at `<root>/session_projcache/sessions/<id>.json` in an owner-only directory tree.
 
-Upgrades never cost the boot or expose an unproven fold. Records stamped with a version in the spec's `compatibleVersions` remain structurally readable for a current checkpoint rewrite, but a missing or older `formatVersion` never matches a current Session and therefore cannot seed hydration. A lifecycle-matching predecessor title remains available only through the listing hint above because title text is invariant across the adjacent Session-format edges and its row still passes the current projection `stateVersion` and schema. Once the format matches, absent lineage fields decode as the unseeded lineage — exact for unseeded sessions, while a seeded caller fails the identity match and refolds cold. A stored record that still fails schema validation is moved aside as `<id>.json.bak.<stamp>` under the domain's `invalidRecords: 'backup-and-skip'` policy, logged with its cause, and rebuilt by the next checkpoint.

 #### What the model sees

 ## Summary
 
-Agents can discover and load skills during a session. Before the first request, they receive a durable catalog of available skill names and capped descriptions, and can use the `skill` tool to load full instructions. Users can invoke a skill with `/name`, which injects the same instructions into that step. Catalog changes append a complete replacement, including an empty catalog that retires old names; configure `catalogDescriptionMaxLength` to limit each description.

 ### 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.

-- **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.
+- **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` avoids duplicating consumer types; 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.

 ### 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。
+- **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` 可避免重复定义消费方类型；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。
+- **写入在提交点之后发出。** `domain/changed` 是通知，不是事务参与者：监听器抛出异常时，系统会隔离该异常并记录警告，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。

 ### 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。

-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、发送相邻 Agent 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`）。

 ## Summary
 
-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, provider-managed process ranges with disclosed weaker fallbacks, and a scrubbed starting environment for every child.

The group provides executable lookup, bounded output capture with spill recovery, provider-managed process ranges with disclosed weaker fallbacks, and a scrubbed starting environment for every child.

 ### 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()` 操作。在受支持的 Linux 宿主上，原始终端 argv 直接在 user-systemd scope 内运行；node-pty PID、session leader、控制终端、前台 `inputWaiting` 与就绪状态保持不变，而 scope 会拥有已重新设定父进程或调用 `setsid` 的后代。在 fallback 宿主上，清理会保留根进程树和可观察 session 中的精确身份，但无法重新发现每个已经逃逸的后代。Linux 的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，上层 PTY 后端会改用空闲推断。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。

 ### 设计理念
 
-每次 spawn 都为信号发送与完全停稳选择同一个 owner。受支持的 Linux 普通命令与终端启动使用临时 user-systemd scope，受支持的 Windows 普通命令使用由 helper 持有、关闭时终止成员的 Job。macOS、旧版或不可用的 user-systemd，以及不可用的 Windows 原生支持使用既有 detached 进程组、`taskkill` 或终端 session 观察，并只告警一次。native 路径可能已经启动命令后，本提供方绝不会通过 fallback 重放该命令。

 ### 主流程
 
-一次 spawn 会同步校验最终 argv、cwd 与环境，在用户命令可能运行前选择 containment，并在目标身份保持私有的情况下返回句柄。Linux 普通命令与终端启动使用私有的一次性请求；scope 内的 bootstrap 会恢复目标 cwd 与环境、解析可执行文件、清除 fd 0 至 fd 2 的 close-on-exec 标记，再以原始 argv 进入 libc `execve()`。Windows 普通命令会隔离 runner 的 fd 0 至 fd 2、把 fd 3 留给 IPC，并用 fd 4 至 fd 6 承载 target stdio；runner 把这些 CRT 描述符解析成 OS handle，以 suspended 状态创建 target，将其加入 Job、恢复运行，再只关闭 carrier 描述符。`done` 会在 direct command 及其 stdio 屏障结算后完成，`waitForExit()` 则分别等待所选 scope、Job、进程组或已观察 session 变空。

 - **native ownership 有明确宿主要求**——Linux 需要可读的 user manager 与 `systemd-run --expand-environment=no`；旧版 systemd 使用带告警的 PGID fallback。macOS 因没有受支持的公开 persistent owner，始终使用该 fallback。
-- **native 选择具有有界的每次 spawn 成本**——Linux 会重复检查 bootstrap 入口、libc `execve`/`fcntl` bindings、存活的 user manager 与 literal-argv scope 支持，直到这套完整探测首次成功；后续符合条件的普通命令或终端 spawn 只重新检查存活的 user manager。Windows 会在每次普通 spawn 前重新检查 runner 入口、bindings 与当前 Job 支持。Linux 深度探测的成功状态与 fallback 告警去重会在 provider 生命周期内持续保留。所有探测都会在用户命令可能运行前完成，子进程探测的超时为 5 秒。每次 Linux 启动都会创建私有请求目录，以 50 毫秒间隔检查尚未确定的 scope 建立状态；scope 已建立且仍 active 后，查询间隔按指数增长，最多为 5 秒。Windows 普通命令会保留一个 runner 与一条 IPC 通道，直到 Job 报告活动进程数为零。目标会直接继承标准句柄，不使用 named-pipe stdio 或结果文件。

 - **Windows Job inheritance 有明确排除项**——普通后代默认继承 Job，但 breakaway 进程不在保证范围。目标只在 Job 分配后启动；runner 若在 create-to-assignment 极窄区间遭外力终止，可能留下 suspended target。
 - **Windows 终端信号是控制台级的**——SIGINT 以 `\x03` Ctrl-C 输入写入投递，由 conhost 转为控制台级 CTRL_C 事件；SIGTSTP 与 SIGHUP 被拒绝（不可用）；不带 `/F` 的 `taskkill` 无法终止控制台进程，因此拆卸的 TERM 档是 `/F` 升级前的宽限等待。Windows 就绪没有精确的 stdin-wait 档：prompt-marker 快路径把 shell pid 作为伪前台进程组比较，其余由静默与计时档覆盖。
-- **fallback 终端 ownership 仍依赖观察**——在 macOS 或缺少可用 user-systemd 的 Linux 上，子进程如果在任何前台检查快照之前重新设定父进程，或离开自有终端 session，就可能逃出进程表扫描。本地提供方不会新增持续进程表监视器；受支持的 Linux native 模式改由 scope membership 持有这些后代。

 - **进程内清理要求退出阶段仍能执行 JavaScript**——直接 `process.exit()`、默认未捕获异常和默认未处理 rejection 会发出 Node 同步 `exit` 事件。未安装 handler 时，`SIGTERM`、`SIGINT` 或 `SIGHUP` 的默认 OS 处置不会发出该事件；应用只有安装执行正常 dispose 或调用 `process.exit()` 的 handler 才能覆盖这些信号。`SIGKILL`、fatal OOM、`process.abort()`、native crash、断电，以及任何无法运行 JavaScript 的故障，都需要外部 supervisor、容器 init 或等价的 OS owner 负责。
 - **凭据清除依赖名称启发式规则**——只匹配 `*KEY*`／`*PASSWORD*`／`*SECRET*`／`*TOKEN*`；名称不同的 secret（例如 `*PASSPHRASE*`）会继续传递，对误删变量引入白名单属于已记录的后续工作。
 - **不会删除已完成的 spill 文件**——有界的完整输出恢复文件会在 OS tmpdir 下累积，直到外部机制进行清理；每进程私有 spill 目录仅在未持有任何已完成 spill 文件时于 JavaScript 可观察的退出阶段删除。

-- **ordinary Job runner 原语** — `CurrentTokenProcessSpawnOptions` 要求已解析的 `applicationName`、完整 target 环境，以及三个专用于 target stdin、stdout 与 stderr 的 runner CRT 描述符。`spawnCurrentTokenJobProcess()` 通过 Node 导出的 `uv_get_osfhandle()` 把这些描述符映射为 OS handle，拒绝无效结果，临时把 handle 设为可继承，并通过 `STARTF_USESTDHANDLES` 传入。它使用 `CREATE_UNICODE_ENVIRONMENT` 传入排序后的 UTF-16LE 环境块，再以 suspended 状态通过 `CreateProcessW` 创建 target、把它分配给 unnamed kill-on-close Job，并只在分配后恢复。原始命令行 argv 项保持不变，runner 也可以关闭自己的 carrier 描述符，而不触碰 Node 自身的标准流。
-- **ordinary 停稳操作** — `pollProcessExit()` 单独发布 direct exit，`isJobEmpty()` 则读取 `QueryInformationJobObject(JobObjectBasicAccountingInformation)`，直到 `ActiveProcesses` 归零。带检查的 Job 终止与 handle 关闭使 runner 保持唯一 native owner。
-- **显式结算归属** — `waitForProcessExit()` 等待并关闭 sandbox process handle；ordinary runner 的 process polling、Job accounting 与 checked Job termination/closure 是独立操作。`drainPipe()` 在排空期间复用一个 native count slot，释放该分配并关闭管道读取句柄。每个调用方拥有自己的 result 组合与返回 handle。

 ## Summary
 
-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.

 ### 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. A relative import that resolves inside the referencing package is followed through that module's re-exports until a package specifier appears, so package-local forwarding modules keep their original declaration references; a relative import that resolves into another package fails. `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.

 ## 概述
 
-使用 `dsh-atomic-write` 替换文件时，不会暴露部分内容，也不会跟随指向临时路径的符号链接。它的写锁会跨进程串行化读-修改-写入循环，因此并发写入方不会用陈旧状态相互覆盖。每次替换都会在全新 inode 上使用调用方选择的权限位，从而安全地收窄现有文件的权限。这个零依赖库只接受字符串；它不提供 `cordis.yml` 插件，也不保证崩溃持久性，因为它不调用 `fsync`。

 ### 写入路径
 
-`writeFileAtomic` 先以独占创建（`wx`）打开一个随机后缀的同级文件并写入内容，然后 rename 到目标上。独占打开拒绝跟随预先埋在可猜测临时路径上的符号链接；同目录兄弟文件保证 rename 落在同一文件系统上；rename 替换的是符号链接目标本身，绝不写穿到其指向的文件。Windows 重试会保留同一份完整的兄弟文件，并采用有界指数退避，因此协作式写锁之外的软件瞬时占用目标时，不会让安全替换立即失败；已归档的[重试决策记录](../../../.agents/notes/archived/bug-fix/2026-08-29-windows-atomic-replace-retry.md)记录了最初的理由与被拒绝的替代方案。

 `withFileLock` 以 `wx` 创建 `<filename>.lock` 同级文件。`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。锁记录创建者的 PID，由持有者在 `finally` 中移除；竞争按指数退避，在每次调用声明的 `waitMs` 期限（默认两秒）过后失败。

 ## Summary
 
-Run a plain-JavaScript orchestration script that fans work out to subagents and returns the script's final JSON value. Scripts can use `agent()`, `parallel()`, `pipeline()`, `phase()`, and `log()`; models normally access them through the `workflow` tool. Each run belongs to its caller, attributes every child to the invoking agent, resolves failures and cancellation without rejecting its result, and stops disposal within a bounded grace period. The caller must supply an execution engine, allowing the isolation strategy to change without altering visible behavior.

-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.

-运行一段纯 JavaScript 编排脚本，将工作扇出给 subagent，并返回脚本的最终 JSON 值。脚本可以使用 `agent()`、`parallel()`、`pipeline()`、`phase()` 和 `log()`；模型通常通过 `workflow` 工具访问它们。每次运行都归调用方所有，将每个子 agent 归属于调用它的 agent，在失败或取消时以结果兑现而不拒绝，并在有界宽限期内完成 dispose。调用方必须提供执行引擎，因此可以更换隔离策略而不改变可见行为。

-**The code preview pins its banner and drops the card fill.** With wrap off, [CodeBody.module.css](../../../../packages/client/ui-sidebar-documentpreview/src/client/code/CodeBody.module.css) sizes the renderer `max-content` so the sticky banner has the full scroll width to ride, and pins the banner `sticky; left: 0; width: 100cqw` against the document scroller (`container-type: inline-size` on the preview body). The shared CodeBlock's fill is routed through a new `--dsl-code-block-background` variable (default unchanged, so chat keeps its gray card) and the shared banner carries an inert `data-code-block-banner` hook; the preview sets the variable to `transparent` so code sits on the pane's own background.
+**The code preview separates its banner from scrolling source and drops the card fill.** The shared CodeBlock wraps its rendered source in a stable `data-code-block-content` node that defaults to `display: contents`, so existing consumers keep their layout.

@@ -52,7 +52,7 @@ Everything host-specific arrives through props:
 
 `DockController` satisfies `DockIntents` as written, so the simplest embedding hands the controller straight to `DockSurface`. An embedder that routes through its own store implements the same method names instead. Three props carry control policy rather than gestures: `canSplit` (surface-wide, the pane budget; disables the split control with `splitPaneDisabled`), `canAddTab(paneId)` (per pane, omits the add control; leave it out to draw one in every pane), and `canCloseTab(tabId)` (per tab, withholds the chip's close control and the menu's close item together; leave it out to keep every tab closable). Hiding the add control moves nothing else in the strip, and a withheld close moves nothing in the chip — the close control paints over the title's end rather than beside it. A pane's lone chip whose close is withheld draws quiet — no capsule, no hover fill — since there is nothing to select against and nothing to do to it. The kit adds one policy of its own, the room rule below, which disables a pane's split control with `splitPaneNarrow`; `onRoom(fits)` reports its readings so an embedder splitting programmatically can honour the same rule.
 
-`dropZones="horizontal"` offers two half-pane hints; once budget or width forbids another split, the whole body accepts a move. A hint is a dashed card inset 8px inside its region, showing the zone's glyph and `labels.dropZone[zone]`; the card under the pointer takes the accent and its neighbour stays a quiet outline. `minPaneFraction` sets the preview minimum, and `planResizeSplit` accepts the same minimum for the committed operation. The Sidebar uses 0.2 and enforces two panes in its own store. The generic engine retains its tree and other split directions. `hideSplitWhenBlocked` hides a blocked split control — pane budget spent or pane too narrow — instead of rendering it disabled; its default is false.
+`dropZones="horizontal"` offers two half-pane hints; once budget or width forbids another split, the whole body accepts a move. A hint is a dashed card inset 8px inside its region, showing the zone's glyph and `labels.dropZone[zone]`; the preview layer covers all tab-body content, while the card under the pointer takes the accent and its neighbour stays a quiet outline. `minPaneFraction` sets the preview minimum, and `planResizeSplit` accepts the same minimum for the committed operation. The Sidebar uses 0.2 and enforces two panes in its own store. The generic engine retains its tree and other split directions. `hideSplitWhenBlocked` hides a blocked split control — pane budget spent or pane too narrow — instead of rendering it disabled; its default is false.
 
 A tab's `kind` is an opaque string. Seeded tabs are factories (`DockControllerOptions`), so what a fresh pane contains is the embedder's decision, not this package's. Content identity is the pair (`kind`, `contentId`): `findContentTab(state, contentId, kind?)` finds the tab showing it anywhere and `findPaneContentTab(state, paneId, contentId, kind?)` within one pane, and `planOpenContent` focuses that tab instead of opening another unless told `revealIfOpened: false`; an explicit `index` seats a new tab at a strip slot rather than at the end.

 `DockController` 原样满足 `DockIntents`，所以最简单的嵌入就是把 controller 直接交给 `DockSurface`。经由自己 store 路由的嵌入方则实现同名方法。有三个 props 承载的是控制策略而非手势：`canSplit`（整面有效，即格预算；用 `splitPaneDisabled` 禁用分栏控件）、`canAddTab(paneId)`（按格，省略添加控件；不传则每格都画）与 `canCloseTab(tabId)`（按 tab，把 chip 的关闭控件和菜单的关闭项一并收起；不传则每个 tab 都可关闭）。隐藏添加控件不会移动 tab 条里的其它任何东西，收起关闭也不会移动 chip 里的任何东西——关闭控件压在标题末端之上而非并排。某格仅剩的一个 chip 在关闭被收起时画成安静样式——没有胶囊底色，没有悬停填充——因为既没有别的 tab 可供选择，也没有任何可对它做的事。套件自己再加一条策略，即下文的空间规则，它用 `splitPaneNarrow` 禁用某格的分栏控件；`onRoom(fits)` 上报其读数，让以编程方式分栏的嵌入方能遵守同一规则。
 
-`dropZones="horizontal"` 提供左右两个半区提示；预算或宽度不允许再拆时，正文整格接收移动。提示是一张内缩 8px 的虚线卡片，显示该落区的图形和 `labels.dropZone[zone]`；指针所在的卡片取强调色，另一张保持安静的轮廓。`minPaneFraction` 控制预览的最小比例，`planResizeSplit` 接受相同最小值以约束提交；Sidebar使用0.2并在自己的store限制两格。通用引擎仍保留原有树与其它分割方向。 `hideSplitWhenBlocked` 在分栏被阻止时（窗格预算已满或格太窄）直接隐藏分栏控件而不是渲染禁用态，默认值为 false。

 tab 的 `kind` 是不透明字符串。种子 tab 是工厂（`DockControllerOptions`），因此新格里放什么由嵌入方决定，与本包无关。内容身份是二元组（`kind`、`contentId`）：`findContentTab(state, contentId, kind?)` 在任意位置找到展示它的 tab，`findPaneContentTab(state, paneId, contentId, kind?)` 在一个格内找；`planOpenContent` 会聚焦该 tab 而非再开一个，除非被告知 `revealIfOpened: false`；显式的 `index` 把新 tab 放到 tab 条的某个位置而非末尾。

 ## What it registers
 
 - **The type** — `ctx.sidebarRightTabs.register(...)` with id `@deepseek-ai/dsh-client-ui-sidebar-documentpreview` (this implementation's identity in the tab system, and the key its body registers under), kind `text`, pattern `dsh-resource://file/**`, band `fallback`. `canOpen` accepts only Session addresses, whose paths may be relative or absolute; bare `absolute` addresses are not claimed. A type registered at the `extension` or `builtin` band for a narrower pattern (say `*.png`) takes those addresses; other supported files land here. The whole address is the content identity, so two files with one name in different directories, or one path under two sessions, are two tabs; the decoded basename is the tab title, and the keyed `sidebar.right.pane.tab.title` seat places its extension-specific `FileTypeIcon` before that title.
-- **The body** — the keyed `sidebar.right.pane.tab` seat under the type's id. Its fixed header shows the Host's absolute path when available, otherwise the requested path; directories use tertiary label colour, the name uses primary label colour, and a clipped path retains and fades toward its final segment while its tooltip exposes the full value. A dropdown selects among matching renderers and plain text. A wrap toggle appears only when the selected renderer declares `wrap: true`; its glyph describes the mode the click selects, and the per-tab preference starts on. Reload stays in this header, not the Sidebar's tab strip. The shared body below owns document scrolling.

Reload stays in this header, not the Sidebar's tab strip. The body reaches every pane edge; each renderer owns its content inset and may own an inner scrollport.
 - **Shared loading and view state**, session-scoped and bucketed by tab id. The store holds accumulated pages or complete bytes, read and observed versions, loading/failure state, renderer choice, scroll offset, wrap, and the answered navigation revision. The ordinary inject face calls Remote readers and writes through declared store actions. Reloads and loading-mode changes retire older requests; the tab's abort signal forgets its state.
 
 Document implementations register metadata with `ctx.documentPreviews.register({ id, extensions, priority, title, loading, wrap? })` and a body under the same `id` in the keyed, Session-scoped `sidebar.right.tab.document` child slot. Own both registrations with effects and wait for the child slot through `ctx.slots.inject`. Bodies receive `resourceAddress`, prepared `content`, `wrap`, and the standard `useTabInfo`/`useResource` hooks; they do not receive a custom resource loader. Metadata declares `loading: 'text-pages'` or `'bytes-complete'`. The registry retains all matching alternatives: `extension` (the default) ranks above `builtin`, then longer suffixes rank first, then registration order. The dropdown preserves a selected implementation while it remains available; removing it selects the next candidate. Builtin bodies use these same registrations.

 - **Complete bytes** — PDF, HTML, and common images use an inject callback to `remote.workspaceFiles.readAll(sessionId, path, signal)`. `rpc.ts` decodes the wire base64 into `data: Uint8Array<ArrayBuffer>` for `{ kind: 'bytes', data }`. The Host's `maxFileBytes` cap rejects oversized files rather than truncating them. PDF copies retained bytes before worker transfer, keeping the Preview buffer usable. Bytes stay in transient view state, never persisted layouts or Session JSONL. Loading-mode changes retire previous results.
 - **Reload** — only the current Preview tab rereads through its Remote callbacks, preserving its scroll preference and retiring older requests. Its change notice compares the read version and the observation captured at read start with later `resource.value.version`; an already observed version does not become a new change after refresh. Reads neither refresh shared metadata nor clear another tab's notice.
 
-HTML runs in a Blob iframe with exactly `sandbox="allow-scripts"`, without `allow-same-origin`; scripts cannot access the parent application's origin or file reader. The renderer loads directly declared relative `.js` classic scripts and `.css` stylesheets through its ordinary inject callback to `remote.workspaceFiles.readRelated`, with fixed safety limits of 4 MiB per asset, 32 MiB total, and 64 distinct assets. Host code resolves the related path; `rpc.ts` decodes the returned bytes. Inside the renderer, base64 is used only to embed the iframe bootstrap payload in script text. A `<base href>` leaves dependency resolution to the browser, as do HTTPS resources. Local module imports, CSS `url()`/`@import`, and dynamic `fetch` do not use Host file access. Read failures, invalid UTF-8, or exceeded limits fail the preview rather than publishing a partial asset package. Replacing or unmounting the document releases its Blob URL.

 PNG, JPEG, GIF, WebP, BMP, ICO, and SVG render through Blob URLs in an `<img>` static-image context. The image keeps its intrinsic CSS-pixel dimensions; a smaller image centres in the shared scroller, and larger dimensions scroll on either axis. The renderer provides neither zoom nor drag-to-pan. SVG markup never enters the application DOM or an iframe, so its scripts cannot execute or reach the parent page. Replacing or unmounting the image revokes its Blob URL.
 
 Shared copy comes from `sidebarDocumentPreview`; each builtin renderer owns its localized labels.
 
-Initial reads, additional pages, and HTML/PDF/image preparation share a loading indicator that respects reduced-motion preferences. Loaded pages stay visible while another page loads. PDF pages form one vertical, width-fitted sequence and render lazily near the viewport. Code previews show source line numbers by default without including them in copied text; plain text uses the same font size and line height as code. Code sits on the pane's own background rather than the chat card's fill, and with wrap off both axes scroll in the shared document scroller while the copy banner stays pinned to the visible width.

 ## Navigation
 
-`ctx.sidebarRight.openResource(address, { params: { line } })` carries a 1-based source line through the `file` parameters. In `text-pages` mode, the owner loads sequential pages until that line or EOF. Plain-text and code renderers expose source-line anchors; Markdown does not. A navigation remains pending while its selected renderer has no anchor and runs if the user switches to plain text or code. Code navigation places the target below its sticky toolbar. Byte-mode renderers do not consume source-line navigation. Each completed navigation revision is answered once. Opening the same file without `revealIfOpened: false` focuses its existing tab and delivers a new revision.

 ## 注册了什么
 
 - **类型** —— `ctx.sidebarRightTabs.register(...)`，id 为 `@deepseek-ai/dsh-client-ui-sidebar-documentpreview`（这个实现在 tab 系统里的唯一键，也是其体注册所用的 key），kind `text`，pattern `dsh-resource://file/**`，档位 `fallback`。`canOpen` 只接受 Session 地址，其中路径可为相对或绝对路径；不认领裸 `absolute` 地址。在 `extension` 或 `builtin` 档以更窄 pattern（比如 `*.png`）注册的类型接走那些地址；其他受支持文件落到这里。整个地址就是内容身份，所以不同目录下同名的两个文件、或同一路径在两个会话之下，是两个 tab；解码后的 basename 是 tab 标题，keyed slot `sidebar.right.pane.tab.title` 会在标题前放置按扩展名选择的 `FileTypeIcon`。
-- **正文** —— keyed slot `sidebar.right.pane.tab`，键为类型的 id。固定头部在可用时显示 Host 的绝对路径，否则显示请求路径；目录使用三级标签色，文件名使用一级标签色，路径过长时保留末段并向开头淡出，提示中仍提供完整值。下拉菜单可在匹配的渲染器与纯文本间切换。仅当所选渲染器声明 `wrap: true` 时显示换行开关；图标表示点击后切换到的模式，该偏好按 tab 保存，初始开启。重新载入仍在此头部，不放入 Sidebar 的 tab 条。下方的共享正文区域负责文档滚动。

Subject: [PATCH 134/164] feat(sidebar): refine guide start page and quiet stat
 pill noise

The guide tab gains a compass hero, per-entry descriptions (shown while
at most four entries are listed), and a quieter cube placeholder for
entries that registered no glyph; the files entry registers its
description and folder glyph. Bundled stat fixes: the session usage
dialog drops the zero cache-write row, and the turn-time pill renders as
plain text when its dialog would only repeat the pill's own duration.

+# Agent Note: Guide start page and stat pill refinements
+
+Status: implemented

+
+## Problem
+
+The right Sidebar's guide tab was a bare list of entry capsules: no visual anchor above them, a capsule could only say its title, and an entry whose type registered no glyph rendered with no icon at all, so a mixed list read as broken rather than sparse. Separately, two chat stat surfaces showed noise: the session token-usage dialog under the composer printed a `Cache write 0 tok` row for sessions that never wrote cache, and the per-turn time pill always opened a dialog even when that dialog held a single row repeating the pill's own label — same formatter, same value — so the click bought nothing.
+
+## Decision
+
+**The guide is a compass over self-describing capsules.** [GuideBody.tsx](../../../../packages/client/ui-sidebar-right/src/client/tabs/guide/GuideBody.tsx) draws a muted 56px compass hero over the entry capsules and no heading, as a browser start page shows its doors without a caption. [`SidebarRightGuideEntry`](../../../../packages/client/ui-sidebar-right/src/client/tab-registry.ts) gains an optional thunked `description` — read fresh on every render like `title`, so language changes need no re-registration. A capsule shows its description under the title only while the guide lists at most `MAX_DESCRIBED_ENTRIES` (4) entries; a longer list drops every description to stay light, so a type must stand on its title. The glyph rides the capsule's height: 22px beside a bare title, 26px beside two lines.
+
+**Icon-less entries fall back to a shipped cube placeholder.** The fallback is decided at the render site (`entry.icon ?? CubeGlyph`), not at registration, so every contributor — builtin or extension — gets it uniformly and a chain replacement of the body replaces the rule with it. `CubeGlyph` lives beside `CompassGlyph` in [GuideTitle.tsx](../../../../packages/client/ui-sidebar-right/src/client/tabs/guide/GuideTitle.tsx): an isometric box in 1.1px straight strokes with rounded joins on `currentColor`, drawn on `--dsw-alias-label-tertiary` — one step quieter than a registered glyph's ink — to mark the slot as unclaimed. The files type registers a description and the shared folder glyph in [definition.tsx](../../../../packages/client/ui-sidebar-files/src/client/definition.tsx).
+
+**The session usage dialog drops the zero cache-write row.** [StatsPills.tsx](../../../../packages/client/ui-chat/src/client/chat/StatsPills.tsx) renders the `Cache write` row only when `cacheWriteTokens !== 0`, as the per-turn panel already drops its absent optional fields; the always-present buckets (input, cache read, output) keep their rows.
+
+**The turn-time pill goes static when its dialog would only repeat it.** [TurnUsagePanel.tsx](../../../../packages/client/ui-chat/src/client/chat/TurnUsagePanel.tsx)'s `TurnTimePanel` renders plain text — no hover, no dialog — exactly when both `tokensPerSecond` and `ttftMs` are undefined, because the dialog's only unconditional row is the duration the pill already shows through the same formatter. With either figure recorded the pill stays a button. The static variant rides the `.trigger` class for geometry and a `.static` class quiets its hover and pointer, keeping the narrow-viewport icon collapse.
+
+## Alternatives considered
+
+**Register the cube in `ui-primitives`.** Its `icons/index.tsx` is the imported figma `ic_ds_*` set, and the cube has a single consumer; `CompassGlyph` set the precedent of package-local guide glyphs.
+
+**Default the icon at registration time.** A `?? default` inside the registry would hide the fallback from the body and make "registered no glyph" undetectable, losing the quieter placeholder ink; explicit render-site fallback keeps registrations honest.
+
+**Show `Cache write 0`.** A session on a provider that never writes cache would carry the row forever; zero here means "not a thing", not a measurement.
+
+**Keep the one-row time dialog.** A dialog whose whole content duplicates its trigger label teaches users that the affordance is empty; hiding the affordance is the honest signal.
+
+## Consequences
+
+`description` is new pre-stable registry API; every consumer was updated (the files entry registers one). The 4-entry threshold is a shipped constant of the guide body, not configuration. Guide-body specs cover the placeholder (size and ink), the description threshold on both sides, and the registered-glyph path; chat-stats specs cover the dropped and present cache-write row; turn-usage-panel specs cover the static pill and both one-figure dialogs. The `ui-sidebar-right` and `ui-sidebar-files` READMEs restate the guide rules.

+# Agent Note: 引导起始页与统计 pill 的细化
+
+Status: implemented
+
+[English](2026-09-10-guide-start-page-and-stat-pill-refinements.md) | 中文
+
+## Problem
+
+右侧边栏的引导 tab 只是一列光秃秃的入口胶囊：上方没有视觉锚点，胶囊只能显示标题，而类型没注册图标的入口干脆不画图标，混合列表看起来像坏了而不是稀疏。另外两个聊天统计面有噪音：输入框下方的会话 token 用量弹窗给从未写入缓存的会话打印一行 `Cache write 0 tok`；turn 级用时 pill 总是可以点开弹窗，即使弹窗只有一行、且内容重复 pill 自己的标签——同一格式化函数、同一数值——点击毫无所得。
+
+## Decision
+
+**引导页是罗盘压着能自我说明的胶囊。** [GuideBody.tsx](../../../../packages/client/ui-sidebar-right/src/client/tabs/guide/GuideBody.tsx) 在入口胶囊上方画一枚弱化的 56px 罗盘，不加标题，如同浏览器起始页不给它的入口配说明文字。[`SidebarRightGuideEntry`](../../../../packages/client/ui-sidebar-right/src/client/tab-registry.ts) 新增可选的 thunk 化 `description`——与 `title` 一样每次渲染重新读取，语言切换无需重新注册。仅当引导页列出的入口不超过 `MAX_DESCRIBED_ENTRIES`（4）个时，胶囊才在标题下显示描述；更长的列表去掉所有描述以保持轻盈，所以类型必须靠标题立得住。图标随胶囊高度变化：单行标题旁 22px，两行旁 26px。
+
+**没有图标的入口回退到内置的立方体占位符。** 回退在渲染点决定（`entry.icon ?? CubeGlyph`）而不在注册时，因此每个贡献者——内置或扩展——得到统一的占位符，链式替换 body 时规则随之整体替换。`CubeGlyph` 与 `CompassGlyph` 一起放在 [GuideTitle.tsx](../../../../packages/client/ui-sidebar-right/src/client/tabs/guide/GuideTitle.tsx)：一只等距视角的盒子，1.1px 直线描边、圆角拼接、走 `currentColor`，用 `--dsw-alias-label-tertiary` 着色——比注册图标的墨色浅一档——标记这个槽位无人认领。files 类型在 [definition.tsx](../../../../packages/client/ui-sidebar-files/src/client/definition.tsx) 注册了描述和共享的文件夹图标。
+
+**会话用量弹窗去掉为零的缓存写入行。** [StatsPills.tsx](../../../../packages/client/ui-chat/src/client/chat/StatsPills.tsx) 仅当 `cacheWriteTokens !== 0` 时渲染 `Cache write` 行，与 per-turn 面板去掉缺失可选字段的做法一致；始终存在的桶（输入、缓存读取、输出）保留各自的行。
+
+**turn 用时 pill 在弹窗只会重复自己时变为静态。** [TurnUsagePanel.tsx](../../../../packages/client/ui-chat/src/client/chat/TurnUsagePanel.tsx) 的 `TurnTimePanel` 恰好在 `tokensPerSecond` 与 `ttftMs` 都缺失时渲染纯文本——无 hover、无弹窗——因为弹窗唯一无条件的行就是 pill 已经用同一格式化函数展示的时长。两者任一有记录时 pill 仍是按钮。静态形态复用 `.trigger` 类保持几何尺寸，再用 `.static` 类压掉 hover 和指针，窄视口的图标折叠行为保持不变。
+
+## Alternatives considered
+
+**把立方体注册进 `ui-primitives`。** 其 `icons/index.tsx` 是导入的 figma `ic_ds_*` 集合，而立方体只有一个消费者；`CompassGlyph` 已开了引导图标包内自持的先例。
+
+**在注册时默认图标。** 注册表内部的 `?? default` 会对 body 隐藏回退，让"没注册图标"无法辨认，浅色占位墨色随之丢失；显式的渲染点回退让注册保持诚实。
+
+**显示 `Cache write 0`。** 用不写缓存的 provider 的会话会永远挂着这一行；这里的零意味着"没有这回事"，不是一次测量。
+
+**保留单行的用时弹窗。** 全部内容都在重复触发器标签的弹窗会教用户认为这个交互是空的；隐藏交互本身才是诚实的信号。
+
+## Consequences
+
+`description` 是新的 pre-stable 注册表 API；所有消费者已同步更新（files 入口注册了一个）。4 个入口的阈值是引导 body 的内置常量，不是配置。guide-body 用例覆盖占位符（尺寸与墨色）、描述阈值两侧和已注册图标路径；chat-stats 用例覆盖缓存写入行的去除与保留；turn-usage-panel 用例覆盖静态 pill 和两种单数据弹窗。`ui-sidebar-right` 与 `ui-sidebar-files` 的 README 重述了引导页规则。

 - **The body** — the keyed `sidebar.right.pane.tab` seat under that id: a header row under the strip, then the tree. The header row is the document preview's (`ui-sidebar-documentpreview`): the root path, its directories greyed and its last segment in full ink, never ellipsized (a path wider than the row keeps its end and fades its start), with the one control, reload, at its right. The row is copied rather than shared because a plugin bundle shares runtime code only through the platform modules; once the artifact and slot surfaces settle, one copy in `ui-primitives` could serve every pane header.
 - **The chip title** — the keyed `sidebar.right.pane.tab.title` seat under that id: a shared `FileTypeIcon` folder glyph at 16px before the type's label. The tree's own rows never draw this sheet.
 
-Seven source files under `src/client/`: `definition.ts` (the type), `store.ts` (what it keeps), `face.ts` (how it lists, Remote binding included), `FilesBody.tsx` (what it draws, with its ordering and failure-line helpers), `FilesTitle.tsx` (the chip title), `locales.ts` (what it says), and `index.ts` (the wiring).

 Default pages depend on the number of registered guide entries, not the number of tab types or open tabs. Exactly one entry opens its page directly (Files in the shipped composition); zero or multiple entries open the guide. Explicitly adding a guide still opens the guide, even with one entry. The sole docked guide is the only tab that cannot close; closing any other sole tab also collapses the column. The chip, context menu, and `close` API apply the same rule.
 
-The guide tab is one entry capsule (a glyph and a title, nothing else) per `guide` entry the registered types contributed, in `order`, centred in the body; the guide has no words of its own. Picking a capsule calls `tab.actions.openTab(entry.kind, { replaceTab: true })`, so the guide gives way to the page it opened. A pane holds at most one guide tab. The strip's add control is drawn only while its pane holds none and opens one there with `openTab('guide', { paneId, revealIfOpened: false })`, so a guide in another pane does not capture the click; opening the guide into a pane that already has one focuses it instead; a guide dragged, dropped, or docked into such a pane merges into it — the arriving guide closes and the pane's own is focused; `duplicateTab` on the guide records nothing. A split, an expanded empty root pane, and the pane a sole tab vacates by dropping on its own edge use the same default-page rule, one tab per new pane; the self-edge drop leaves the dragged tab focused. A plain `openTab('guide')` opens or focuses the guide only within the active or named pane. Splitting an empty pane does nothing and returns no new pane. The product allows two horizontal panes, initially equal, with divider ratios limited to 20%–80%. Insufficient width blocks a new split; with two panes already present, a body drop moves the tab between panes instead of creating a third. At the two-pane limit, split controls are hidden; closing back to one pane restores them.
+The guide tab is a muted compass over one entry capsule per `guide` entry the registered types contributed, in `order`, centred in the body; the guide has no words of its own. A capsule shows the entry's glyph — or the guide's quieter cube placeholder when the entry registered none — and its title; while at most four entries are listed, an entry that registered a `description` shows it under the title, and a longer list drops every description.

Subject: [PATCH 135/164] fix(sidebar): pin the guide hero to the pure-gray
 ramp

The label-dimmed alias rides the bluish neutral ramp, whose cast shows
at the 56px compass; the hero now takes neutral-200 (light) and
neutral-700 (dark) from the pure-gray static ramp.

 循环在每个派生消息对象首次进入请求时执行深冻结，并且仅在同一 agent 内复用该证明。恢复的消息保留对象身份；构造请求不会冻结包含消息的事件包装对象。每个请求都会冻结本地规范化 header、新消息数组和请求封装，同时保留取消信号的可变性。[请求冻结决策](../../../.agents/notes/implemented/simplification/2026-09-06-agent-request-freeze-provenance.zh.md)解释了所有权与测量依据。

 ## What it registers
 
 - **The type** — `ctx.sidebarRightTabs.register(...)` with id `@deepseek-ai/dsh-client-ui-sidebar-documentpreview` (this implementation's identity in the tab system, and the key its body registers under), kind `text`, pattern `dsh-resource://file/**`, band `fallback`. `canOpen` accepts only Session addresses, whose paths may be relative or absolute; bare `absolute` addresses are not claimed. A type registered at the `extension` or `builtin` band for a narrower pattern (say `*.png`) takes those addresses; other supported files land here. The whole address is the content identity, so two files with one name in different directories, or one path under two sessions, are two tabs; the decoded basename is the tab title, and the keyed `sidebar.right.pane.tab.title` seat places its extension-specific `FileTypeIcon` before that title.
-- **The body** — the keyed `sidebar.right.pane.tab` seat under the type's id. Its fixed header shows the Host's absolute path when available, otherwise the requested path; directories use tertiary label colour, the name uses primary label colour, and a clipped path retains and fades toward its final segment while its tooltip exposes the full value. A dropdown selects among matching renderers and plain text. A wrap toggle appears only when the selected renderer declares `wrap: true`; its glyph describes the mode the click selects, and the per-tab preference starts on. Reload stays in this header, not the Sidebar's tab strip. The body reaches every pane edge; each renderer owns its content inset and may own an inner scrollport.

Reload stays in this header, not the Sidebar's tab strip. The body reaches every pane edge; each renderer owns its content inset and may own an inner scrollport. This intentionally differs from the Files tab's 2px right-side scrollbar offset: previews keep the full pane width so edge-to-edge HTML and code scrollports end at the pane edge.
 - **Shared loading and view state**, session-scoped and bucketed by tab id. The store holds accumulated pages or complete bytes, read and observed versions, loading/failure state, renderer choice, scroll offset, wrap, and the answered navigation revision. The ordinary inject face calls Remote readers and writes through declared store actions. Reloads and loading-mode changes retire older requests; the tab's abort signal forgets its state.
 
-Document implementations register metadata with `ctx.documentPreviews.register({ id, extensions, priority, title, loading, wrap? })` and a body under the same `id` in the keyed, Session-scoped `sidebar.right.tab.document` child slot. Own both registrations with effects and wait for the child slot through `ctx.slots.inject`. Bodies receive `resourceAddress`, prepared `content`, `wrap`, and the standard `useTabInfo`/`useResource` hooks; they do not receive a custom resource loader. Metadata declares `loading: 'text-pages'` or `'bytes-complete'`. The registry retains all matching alternatives: `extension` (the default) ranks above `builtin`, then longer suffixes rank first, then registration order. The dropdown preserves a selected implementation while it remains available; removing it selects the next candidate. Builtin bodies use these same registrations.

 ## 注册了什么
 
 - **类型** —— `ctx.sidebarRightTabs.register(...)`，id 为 `@deepseek-ai/dsh-client-ui-sidebar-documentpreview`（这个实现在 tab 系统里的唯一键，也是其体注册所用的 key），kind `text`，pattern `dsh-resource://file/**`，档位 `fallback`。`canOpen` 只接受 Session 地址，其中路径可为相对或绝对路径；不认领裸 `absolute` 地址。在 `extension` 或 `builtin` 档以更窄 pattern（比如 `*.png`）注册的类型接走那些地址；其他受支持文件落到这里。整个地址就是内容身份，所以不同目录下同名的两个文件、或同一路径在两个会话之下，是两个 tab；解码后的 basename 是 tab 标题，keyed slot `sidebar.right.pane.tab.title` 会在标题前放置按扩展名选择的 `FileTypeIcon`。
-- **正文** —— keyed slot `sidebar.right.pane.tab`，键为类型的 id。固定头部在可用时显示 Host 的绝对路径，否则显示请求路径；目录使用三级标签色，文件名使用一级标签色，路径过长时保留末段并向开头淡出，提示中仍提供完整值。下拉菜单可在匹配的渲染器与纯文本间切换。仅当所选渲染器声明 `wrap: true` 时显示换行开关；图标表示点击后切换到的模式，该偏好按 tab 保存，初始开启。重新载入仍在此头部，不放入 Sidebar 的 tab 条。正文贴合格的每条边，各渲染器自行提供内容留白，并可拥有内部滚动区。

 - **共享加载与视图状态**，会话作用域、按 tab id 分桶。store 持有累计页或完整字节、读取与观察版本、加载/失败状态、渲染器选择、滚动位置、换行和已响应的导航 revision。普通 inject face 调用 Remote 读取，并经声明的 store action 写入。重新载入和加载模式变化会淘汰旧请求；tab 的中止信号清理其状态。
 
-文档实现在 `ctx.documentPreviews.register({ id, extensions, priority, title, loading, wrap? })` 注册元数据，并以相同 `id` 向 keyed、Session 作用域的子 slot `sidebar.right.tab.document` 注册正文。两处注册都由 effect 持有，通过 `ctx.slots.inject` 等待子 slot。正文接收 `resourceAddress`、准备好的 `content`、`wrap` 和标准 `useTabInfo`/`useResource` 钩子，不接收自定义资源加载器。元数据声明 `loading: 'text-pages'` 或 `'bytes-complete'`。注册表保留所有匹配备选：`extension`（默认）优先于 `builtin`，随后按更长的后缀、再按注册顺序排列。所选实现仍可用时，下拉选择保持不变；移除后选择下一个候选。内置正文也使用相同注册方式。

 未打包产物包含四块相互独立的体积：Electron、离线 seed 存储分片与本地 dsh tarball、上游 Node.js 与 pnpm 运行时，以及很小的桌面壳应用。分片不压缩，使外层 DMG、ZIP 或 NSIS 压缩器与差分更新器可以处理稳定的数据区间。文件系统占用不等于安装包下载大小，因此必须分别测量。打包应用首次启动时还会先把 seed 存储解包到 `$DSH_HOME/desktop/pnpm/store`，再安装可写 profile，因此发布验证必须同时测量应用与 Harness home 的磁盘占用。

-Client journal 在发布 follow 快照、live entry 或历史页之前验证精确的 V3 事件 envelope。它复用浏览器安全的 Session validator，检查必需的 surface marker、精确的 replacement endpoint、更早且唯一的 source seq、内嵌 Assistant 来源、request header 可选字段的省略规则以及 工具错误一致性。无效 record 直接失败，不删除字段或归一化；范围成员与来源存在性仍由 Host 的持久日志检查。

 每个 endpoint 都声明自己的激活策略。列表只读取持久化 header 与 projection cache row，绝不调用逐 Session stat 或打开冷 Session body。当前格式 cache identity 可以提供全部列表 hint；生命周期匹配的 predecessor cache 只能提供版本兼容的 title，作为可能过时的展示事实，绝不能作为权威 fold seed。搜索、附件、历史页、日志跟随、skill 发现和工作区路径打开可以在不激活 Agent 的情况下检查 persistence；`canOpenWorkspacePath()` 无需指定 Session 即可报告原生打开能力。queue 变更与取消要求 live 状态；模型、重命名、prompt 和文件引用操作可以解析或恢复普通 Session。提示词会在解析 Agent 或追加 Session 事件前，拒绝既没有非空白文本也没有附件的 content；queue edit 只接受非空文本 content。prompt 准入从注入的 [`fileUploads`](../../client/file-upload/README.zh.md) Host 服务取得不透明凭证，在把完整有序内容列表交给 `ctx.attachments` 前解析每个属于同一 Agent 的凭证。`requestId` 已进入 queue 或日志时，prompt 重试直接返回原来的接受结果，不会重复插入消息。只有 create 与 fork 会直接创建新 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。Queue 变更只有一个狭窄例外：当前 projection identity 为 continuable 且来自自身非 seed suffix 的在线 child，可以在两个 inbox 目标上使用普通 Edit、Remove 与 QueueDock Steer action。One-shot、缺失、未知、损坏、仅含 seed identity 或冷 child 继续被拒绝，且不会恢复。skill 目录优先使用已有 live Agent，否则使用所记录 preset 的常驻 scope，因此列表查询绝不会启动 Agent。 经过鉴权的文件交付路由通过 `workspaceDesktop()` 获取提供服务的 Host 名称和文件管理器行为。`openWorkspacePath({ path, action: "reveal" })` 将文件管理器导航委托给原生适配器；省略 `action` 时打开默认应用。
 
-Client 适配器提供 `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`、`append` 与 `settle-assistant` 变更，并通过 tail page 修复重连或 seq 缺口。向后分页有两个动词：`loadOlder()` 拉一页 50 条消息，而 `loadThrough(seq)`——轮次跳转加载器——按每页 200 条消息循环拉取直到窗口覆盖目标 seq，重复调用会下调共享目标，遇到无进展的页即停止，忙碌状态复用同一个 `loadingOlder` 快照位。Web 适配器 显式选择接收无 cursor 的 Assistant frame：每个 opening 携带活跃 attempt 的 `startedAfterSeq`、`nextIndex` 与紧凑 stream，每个 stream member 都成为排在持久 cursor 之间的 Client-only `assistant/live-chunk` 条目。Host 会随该 baseline 捕获 follower 本地到达序号，并抑制该 cut 及之前的 buffered frame；replacement Agent 可以从 revision 一重新开始。活跃 opening 之后到达的持久 `assistant/message` 或 `assistant/attempt` 只有在其 seq 晚于 `startedAfterSeq` 且 轮次与步骤 匹配时才会保持暂存；匹配的 end type、seq 与 index 会发布一个具名 settlement delta，删除该 attempt 的瞬态 row、加入持久条目，并保留同一步骤中更早的 retry。已知 attempt 的 revision、密集 index 或 settlement 缺口会重新打开 follow；若 controller 错过 start，则忽略 unknown-attempt frame，并正常发布其持久 settlement。Abandoned end 会发布不含持久条目的 settlement delta，使瞬态 row 立即退出。持久缺口修复 page 不携带 Assistant baseline，因此 held notification 会重新打开 follow 一次，以取得配对的 page 与 baseline。每条历史 record 只覆盖自身的事件 seq。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持久事件。每次 inbox 变更时，Host 会先发布 projection frame，再从同一份已校验的折叠后值派生 queue replacement，因此监听器注册顺序不会产生陈旧的 queue frame。Client Agent 上下文提供独立 [`fileUpload`](../../client/file-upload/README.zh.md) 服务使用的身份；Session 对象提供生命周期、prompt、queue 与历史操作，不提供文件传输。

 Session 对象还承载本地提交回显：`session.beginSubmission` 在调用方序列化与提示词之前，同步把一条回显写入 `SessionSnapshot.pendingSubmissions`，会话 UI 因此能在点击提交的当帧显示消息。回显按顺序存放图片预览与持久文件引用。Session 根据当前运行状态与请求的投递模式推导其 `transcript`、`queued` 或 `steering` 位置，并在序列化期间保留该位置。提示词的 `requestId` 是关联标识：Host 把它回显为 durable user source 的 `rpcId`，queue occurrence 也把它投影为 `SessionQueuedItem.rpcId`。回显在观察到其 durable event 或 queue occurrence 后延迟一个动画帧退休，带标识的提示词失败或被放弃时立即退休，销毁时按 failed 退休。每次退休恰好触发一次 `onRetire`；observed 退休还会携带有序的持久附件引用，让 composer 释放成功卡片并保留失败草稿。回显只存在于 Client 内存；刷新与重连只从持久事件重建会话。

 ## 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 的注册表 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 位于独立包，由各自包注册 Definition、快照 builder、View 和 renderer。

-`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 事件源。

 适配器把每个 `SessionEventLikeEntry` 直接交给 assembler。外层 `type` 区分持久事件与 Client-only transient event，内部 `event` 则统一公开 `type`、`seq`、`time` 与 `data`；Definition 接收这个内部 `SessionEventLike`。replacement window 可以包含两种 entry，历史 prepend 携带持久 entry，实时 append 则可以携带任一种。两种事件都使用 Definition 的同一组 `match` 与 `update` 方法，`start` 只接收持久 event，assembler 会拒绝 transient start。不消费 Assistant delta 的 Definition 对 `assistant/live-chunk` 返回 `null`。replace window 或 revision 断档从完整已加载窗口重建；连续 revision 的 append、prepend 与 Assistant settlement 使用增量组装。settlement 只删除具名 attempt 的 transient match，应用可选持久 entry，并重放受影响的 Context 及其 dependent，不替换无关 target node。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`。

-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（文本记录）、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。每个完成结算的模型尝试 都会提交一个事件：`assistant/message` 携带组装后的模型可见 message 及其紧凑带时间 stream，`assistant/attempt` 则保留失败、重试、取消或 stream error attempt，且不添加模型历史。如果进程在 settlement 前硬中断，则不会留下持久 attempt stream。

 <a id="use-this-package"></a>
 ## Use this package
 
-Four artifacts from one tsdown pipeline:
+Three build artifacts and one source-owned process layer:
 
 - **`lib/index.js` (assembly library)** — `createWorkerHost`/`startWorkerHost` mount the base image and any ordered data overlays (`storage/`), install the module loader (`module-system/`) and the `process` shim, boot the tree through the image's own `dsh-app-boot`, and hand the tunnel its serving seams. Overlays may replace files only under `home/` and `workspace/`; they cannot replace the base manifest, configuration, or modules. The image layout contract (`image-layout.ts`: virtual root, config/manifest paths, empty directories, the `lowered` wrapper-contract gate) is shared with the packer. Boot patches force the deployment-shaped rows: frontend serving off, JSONL session logs on the plaintext path, preset roots onto the image's `config/agent-presets`.
 - **`lib/worker.js` (worker bundle)** — the assembly plus this package's Node-compatibility layer as one self-contained ES module. The module proxy table (`module-proxies.ts`) is the only platform fork: `node:*` builtins over VFS/tunnel/browser primitives, structural stubs that fail loud on the console for what a browser cannot do, and native/binary package replacements. `node:module` supplies `createRequire().resolve` and `.resolve.paths()` over the image package root, so unchanged packages can discover manifests without evaluating their modules. The global `process` shim carries Node detection fields including `title`, preventing Worker execution from entering DOM-only branches. The pack-time parser reports statically named module requests, including module-scope direct calls of the form `createRequire(import.meta.url)('pkg')` through a named `node:module` or `module` import, to the packer's reachability walk. Stored, CommonJS-obtained, and rebased `createRequire` calls require image entry seeds. VFS mutations drive `node:fs` callback, polling, and promise watchers; open descriptors retain file identity and access mode across rename, replacement, and unlink, `FileHandle.stat({ bigint: true })` reports the same device and inode identity as a path stat while the name still refers to that file, and `FileHandle.chmod()` updates the opened file identity; `readable-stream` supplies the stream state machine used by file streams and unchanged image packages such as Chokidar and readdirp. AsyncLocalStorage carries sync-stack causality across `await` through the snapshot/restore faces the pack-time lowering injects. The worker holds no compiler: an image the packer did not lower is refused at mount.

 ## 使用本包
 
-一条 tsdown 管线产出四项内容：
+一条 tsdown 管线产出三个构建产物，以及一层由源码维护的进程实现：
 
 - **`lib/index.js`（装配库）**——`createWorkerHost`/`startWorkerHost` 挂载基础镜像和按序排列的数据 overlays（`storage/`）、安装模块加载器（`module-system/`）与 `process` shim、经镜像自带的 `dsh-app-boot` 启动插件树，并把服务 seam 交给隧道。Overlay 只能替换 `home/` 与 `workspace/` 下的文件，不能替换基础 manifest、配置或模块。镜像布局契约（`image-layout.ts`：虚拟根、config/manifest 路径、空目录、`lowered` 包装契约门）与 packer 共享。boot patch 强制部署形态行：关前端静态服务、JSONL 会话日志走明文、preset 根指向镜像内 `config/agent-presets`。
 - **`lib/worker.js`（worker 束）**——装配库加本包的 Node 兼容层，合成一个自含 ES module。模块代理表（`module-proxies.ts`）是唯一平台叉口：`node:*` 内建走 VFS、隧道和浏览器原语，浏览器做不到的走结构化 stub（调用即在 console 报错并抛出），native/binary 包则替换执行后端。`node:module` 在镜像 package 根之上提供 `createRequire().resolve` 与 `.resolve.paths()`，使未修改的包无需执行目标模块即可发现 manifest。全局 `process` shim 带有包括 `title` 在内的 Node 环境识别字段，避免 Worker 执行误入仅适用于 DOM 的分支。pack 期解析器会把名称静态可知的模块请求报告给 packer 的可达性遍历，其中包括通过 `node:module` 或 `module` 具名导入在模块作用域直接发起的 `createRequire(import.meta.url)('pkg')` 调用。保存、经 CommonJS 获取或另设基准的 `createRequire` 调用需要镜像入口种子。VFS mutation 驱动 `node:fs` 的 callback、polling 和 promise watcher；打开的 descriptor 在 rename、replacement 和 unlink 后仍保留文件身份与访问模式，只要文件名仍指向该文件，`FileHandle.stat({ bigint: true })` 报告的 device 与 inode 身份就与路径 stat 相同，`FileHandle.chmod()` 则更新打开文件身份的权限；`readable-stream` 提供文件流以及 Chokidar、readdirp 等未修改镜像包所用的流状态机。AsyncLocalStorage 经 pack 时降低注入的 snapshot/restore 面在 `await` 间携带同步栈因果。worker 不带编译器：packer 未降低的镜像在挂载时被拒。

 Client 适配器提供 `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`、`append` 与 `settle-assistant` 变更，并通过 tail page 修复重连或 seq 缺口。向后分页有两个动词：`loadOlder()` 拉一页 50 条消息，而 `loadThrough(seq)`——轮次跳转加载器——按每页 200 条消息循环拉取直到窗口覆盖目标 seq，重复调用会下调共享目标，遇到无进展的页即停止，忙碌状态复用同一个 `loadingOlder` 快照位。Web 适配器显式选择接收无 cursor 的 Assistant frame：每个 opening 携带活跃 attempt 的 `startedAfterSeq`、`nextIndex` 与紧凑 stream，每个 stream member 都成为排在持久 cursor 之间的 Client-only `assistant/live-chunk` 条目。Host 会随该 baseline 捕获 follower 本地到达序号，并抑制该 cut 及之前的 buffered frame；replacement Agent 可以从 revision 一重新开始。活跃 opening 之后到达的持久 `assistant/message` 或 `assistant/attempt` 只有在其 seq 晚于 `startedAfterSeq` 且轮次与步骤匹配时才会保持暂存；匹配的 end type、seq 与 index 会发布一个具名 settlement delta，删除该 attempt 的瞬态 row、加入持久条目，并保留同一步骤中更早的 retry。已知 attempt 的 revision、密集 index 或 settlement 缺口会重新打开 follow；若 controller 错过 start，则忽略 unknown-attempt frame，并正常发布其持久 settlement。Abandoned end 会发布不含持久条目的 settlement delta，使瞬态 row 立即退出。持久缺口修复 page 不携带 Assistant baseline，因此 held notification 会重新打开 follow 一次，以取得配对的 page 与 baseline。每条历史 record 只覆盖自身的事件 seq。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持久事件。每次 inbox 变更时，Host 会先发布 projection frame，再从同一份已校验的折叠后值派生 queue replacement，因此监听器注册顺序不会产生陈旧的 queue frame。Client Agent 上下文提供独立 [`fileUpload`](../../client/file-upload/README.zh.md) 服务使用的身份；Session 对象提供生命周期、prompt、queue 与历史操作，不提供文件传输。

+一条 tsdown 管线产出三个构建产物；另有一层由源码维护的进程实现：
 
 - **`lib/index.js`（装配库）**——`createWorkerHost`/`startWorkerHost` 挂载基础镜像和按序排列的数据 overlays（`storage/`）、安装模块加载器（`module-system/`）与 `process` shim、经镜像自带的 `dsh-app-boot` 启动插件树，并把服务 seam 交给隧道。Overlay 只能替换 `home/` 与 `workspace/` 下的文件，不能替换基础 manifest、配置或模块。镜像布局契约（`image-layout.ts`：虚拟根、config/manifest 路径、空目录、`lowered` 包装契约门）与 packer 共享。boot patch 强制部署形态行：关前端静态服务、JSONL 会话日志走明文、preset 根指向镜像内 `config/agent-presets`。
 - **`lib/worker.js`（worker 束）**——装配库加本包的 Node 兼容层，合成一个自含 ES module。模块代理表（`module-proxies.ts`）是唯一平台叉口：`node:*` 内建走 VFS、隧道和浏览器原语，浏览器做不到的走结构化 stub（调用即在 console 报错并抛出），native/binary 包则替换执行后端。`node:module` 在镜像 package 根之上提供 `createRequire().resolve` 与 `.resolve.paths()`，使未修改的包无需执行目标模块即可发现 manifest。全局 `process` shim 带有包括 `title` 在内的 Node 环境识别字段，避免 Worker 执行误入仅适用于 DOM 的分支。pack 期解析器会把名称静态可知的模块请求报告给 packer 的可达性遍历，其中包括通过 `node:module` 或 `module` 具名导入在模块作用域直接发起的 `createRequire(import.meta.url)('pkg')` 调用。保存、经 CommonJS 获取或另设基准的 `createRequire` 调用需要镜像入口种子。VFS mutation 驱动 `node:fs` 的 callback、polling 和 promise watcher；打开的 descriptor 在 rename、replacement 和 unlink 后仍保留文件身份与访问模式，只要文件名仍指向该文件，`FileHandle.stat({ bigint: true })` 报告的 device 与 inode 身份就与路径 stat 相同，`FileHandle.chmod()` 则更新打开文件身份的权限；`readable-stream` 提供文件流以及 Chokidar、readdirp 等未修改镜像包所用的流状态机。AsyncLocalStorage 经 pack 时降低注入的 snapshot/restore 面在 `await` 间携带同步栈因果。worker 不带编译器：packer 未降低的镜像在挂载时被拒。

 ### 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 agent-preset roster is an optional peer resolved per call through `ctx.get('agentPresets')`: its `compositionInventory()` owns every preset read, and this package only maps root-fiber states onto the public phase vocabulary.

 ### 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.

Modal state lives in a snapshot store keyed by session, so the button and the command share one dialog per session.
 
 The Host route is a feature-owned exact Fetch contribution. Connection applies its Host/Origin and browser-session checks and bridges the streaming `Response`; this package owns query validation, live-session flushes, handle-based log reads and attachment reads, ZIP generation, and HTTP status semantics.

 `priority` is one of three literal bands, spelled as strings so that a type from another package needs no runtime import: `extension` is the band of a type from outside the product and the highest, so a type that declares nothing outranks every viewer shipped here; `builtin` is the ordinary band for shipped types; `fallback` is the plain-content position that anything more specific should beat, which VS Code's text editor holds implicitly and our text preview holds explicitly. `candidates(address)` returns every type whose globs match and whose `canOpen` does not veto, ranked by band, then by the length of the longest pattern that matched, then by registration order. `claim(address, kind?)` takes the best candidate, or the named kind's type in force when the caller overrides (its globs are not consulted; naming the type is the decision), and throws for an address nothing will open — a wiring mistake, not a user error. `get(kind)` returns the type in force; `entries()` and `guide()` list the types and their guide boxes in force; `subscribe` observes changes.

The tab's title is `开始` / `Start`, captured into the layout record when the pane is seeded, so a later language change relabels the type and not tabs already open.

The boxes are projected from every registered type's `guide[]` in `order`, through the registry's observable `guide()` list, so a type registering later appears without the guide knowing it. A box shows the contributing type's glyph, title, and description, and picking it calls `tabActions.openTab(entry.kind, { replaceTab: true })`: the picked type opens in the guide's own tab, and the guide is gone.

 The body is also the replacement seam. It renders the `sidebar.right.tab.guide` chain with the shipped guide as the chain's fallback, so a product that registers its own entry takes the whole body, and with no entry, or every entry declining, the shipped guide draws. Because the shipped guide is the fallback and not a chain entry, there is always exactly one body and it cannot be outvoted by accident.

 A failed read keeps content already shown and adds a localized failure with a retry action. The Preview names actionable file failures and falls back to the carrier message for other codes; `outside-workspace` belongs to directory listing and is not a Preview-specific failure.

Its registration is `{ kind: 'files', id: '@deepseek-ai/dsh-client-ui-sidebar-files', priority: 'builtin', title, guide: [{ order: 10, title, description, icon: IconFolderClose16 }] }` — no `patterns`, because nothing navigates *to* a file tree by address; the guide's entry box opens the type itself. `id` is the implementation's identity in the Tab system and doubles as the `key` of the body seat `sidebar.right.pane.tab`, so the same string names the type and the component that draws it. `register()` returns a disposer and goes through `ctx.effect`, as every registration does.

 The root is the session's working directory as the Host reports it in the session list (`useSessions().byId[sessionId].cwd`), labelled by `workspaceTitleOf` from `dsh-util-workspace-path` — the final non-empty path segment — with the root string itself as the label when the path is separator-only. A session without a working directory shows one line (`noWorkspace`) and issues no request. There is no root chooser and no way to browse upward: the Host's `list` refuses paths outside the Session's workspace root, so the one directory the client can list is the one it shows.

 ## Problem
 
-The right Sidebar's guide tab was a bare list of entry capsules: no visual anchor above them, a capsule could only say its title, and an entry whose type registered no glyph rendered with no icon at all, so a mixed list read as broken rather than sparse. Separately, two chat stat surfaces showed noise: the session token-usage dialog under the composer printed a `Cache write 0 tok` row for sessions that never wrote cache, and the per-turn time pill always opened a dialog even when that dialog held a single row repeating the pill's own label — same formatter, same value — so the click bought nothing.

A capsule shows its description under the title only while the guide lists at most `MAX_DESCRIBED_ENTRIES` (4) entries; a longer list drops every description to stay light, so a type must stand on its title. The glyph rides the capsule's height: 22px beside a bare title, 26px beside two lines.

The glyph rides the capsule's height: 22px beside a bare title, 26px beside two lines.
 
 **Icon-less entries fall back to a shipped cube placeholder.** The fallback is decided at the render site (`entry.icon ?? CubeGlyph`), not at registration, so every contributor — builtin or extension — gets it uniformly and a chain replacement of the body replaces the rule with it. `CubeGlyph` lives beside `CompassGlyph` in [GuideTitle.tsx](../../../../packages/client/ui-sidebar-right/src/client/tabs/guide/GuideTitle.tsx): an isometric box in 1.1px straight strokes with rounded joins on `currentColor`, drawn on `--dsw-alias-label-tertiary` — one step quieter than a registered glyph's ink — to mark the slot as unclaimed. The files type registers a description and the shared folder glyph in [definition.tsx](../../../../packages/client/ui-sidebar-files/src/client/definition.tsx).
 
-**The session usage dialog drops the zero cache-write row.** [StatsPills.tsx](../../../../packages/client/ui-chat/src/client/chat/StatsPills.tsx) renders the `Cache write` row only when `cacheWriteTokens !== 0`, as the per-turn panel already drops its absent optional fields; the always-present buckets (input, cache read, output) keep their rows.
-
-**The turn-time pill goes static when its dialog would only repeat it.** [TurnUsagePanel.tsx](../../../../packages/client/ui-chat/src/client/chat/TurnUsagePanel.tsx)'s `TurnTimePanel` renders plain text — no hover, no dialog — exactly when both `tokensPerSecond` and `ttftMs` are undefined, because the dialog's only unconditional row is the duration the pill already shows through the same formatter. With either figure recorded the pill stays a button. The static variant rides the `.trigger` class for geometry and a `.static` class quiets its hover and pointer, keeping the narrow-viewport icon collapse.

+`dsh-llm` defines `SystemPromptUpdate = 'in-history'` and carries it as an optional sibling field, `systemPromptUpdate`, on `LlmResolvedModelInfo` and `PreparedLlmCall`; `normalizeModelInfo` rejects any other value with an `LlmError` whose code is `INVALID_MODEL_INFO`. The DeepSeek adapter's catalog model (`DeepSeekCatalogModel.systemPromptUpdate`, validated by zod at load) and the replay provider's `ReplayModelConfig.systemPromptUpdate` declare it per model; absence means the model needs message 0 rewritten. The sole built-in entry in `dsh-llm-deepseek`, `deepseek-flash`, declares it alongside text and image input. This exact catalog entry records the model capability; names and protocol families do not imply support for other models. A deployment can replace the catalog through the `models` list in `cordis.yml`, and every `dsh-llm-pi-ai` route keeps the replace behaviour.
 
 The loop records the mode in the session: `RequestContext.systemPromptUpdate` joins provider, model, and capacity as a `request/context` field, logged whenever any of them differs from the latest snapshot. Admission reads `PreparedLlmCall.systemPromptUpdate` from the actual call prepared after `agent/request`; the preceding snapshot is not an admission input. First requests, resumed sessions, route changes, and same-route capability changes therefore use the capability of the bound adapter that will serve the call.

 循环把该模式记录进会话：`RequestContext.systemPromptUpdate` 与 provider、model、容量并列成为 `request/context` 的字段，其中任一项与最新快照不同时就记录一次。准入读取 `agent/request` 之后实际准备调用的 `PreparedLlmCall.systemPromptUpdate`；先前快照不是准入输入。因此首次请求、恢复的会话、路由变更以及同一路由的能力变更，都使用将服务该调用的绑定适配器的能力。

+# Agent Note: Public package manifest fields
+

+
+## Problem
+
+Plugin authors need npm identity, runtime requirements, and DSH declarations from one public import. Internal image-packaging, Session catalog, and generated proxy metadata do not define extension points for community plugins. Exposing those fields together makes internal mechanisms appear available to external authors.
+
+## Decision
+
+[`DshPackageManifest`](../../../../packages/util/package-manifest/src/types.ts) describes the package.json fields DSH uses, with required `name` and `version`. Its optional `dsh` member uses `DshManifest` for public composition and author metadata. The type is a selected npm field set, not a complete package.json schema. App-boot adapts it with `Partial` for local profiles, which need no published identity.
+
+Runtime requirements live at top-level `engines`: `dsh`, `node`, and `npm` are optional version strings, and other engine names are allowed. `dsh.manifestVersion` identifies declaration format `1`; `dsh.categories` carries free-form discovery tags without restricting package composition. Format and DSH compatibility declarations are not enforced by current installers or loaders.
+
+The image packer owns `configTrees`, the workspace catalog generator owns Session migration declarations, and app-boot owns generated module-fallback metadata. Their existing on-disk keys remain readable by those internal tools, but the public manifest types do not expose them. This scope refines the [shared declaration ownership decision](2026-09-05-package-manifest-types.md), whose package placement and dependency rules remain active.
+
+Each consumer owns JSON parsing, field validation, default resolution, and adaptation to runtime data. Interfaces do not validate parsed JSON. A helper belongs in the shared package only when multiple consumers need the same validation or normalization; getters that repeat property access add no shared policy.
+
+## Alternatives considered
+
+**Keep internal metadata in the public declaration.** A workspace-only migration catalog and an experimental image packer cannot offer public plugin behavior merely because their metadata is discoverable.
+
+**Put DSH compatibility under `dsh.engines`.** [VS Code](https://code.visualstudio.com/api/references/extension-manifest) places its host requirement in top-level `engines.vscode`. Top-level `engines.dsh` gives authors one location for runtime requirements; DSH still owns enforcement of its custom key.
+
+**Use peer dependencies as the sole host requirement.** Peer dependencies constrain installed npm packages, including the CLI package `@deepseek-ai/dsh`. They do not identify the currently running DSH process when plugins live in a separate profile project.
+
+**Parse every domain through one mandatory parser.** Existing readers consume different subsets and own different errors and defaults. Combining them would make a client reader validate unrelated profile declarations. The public types remain independent of filesystem access and parsing policy.
+
+## Consequences
+
+External authors gain a complete package-level declaration and a smaller DSH author API. Consumers of removed internal types must use their owning implementations. The packer and repository catalog no longer depend on the public declaration package; app-boot retains a production dependency because its published profile type references it.
+
+Compiler and built NodeNext import checks verify required package identity, partial profiles, top-level engine declarations, and the absence of internal fields from the public API. Existing profile, packer, and Session catalog tests retain coverage of their accepted files and malformed declarations. No Session format, plugin loading rule, or model-visible behavior changes.

+# Agent Note: 公共 package manifest 字段
+
+Status: implemented
+
+[English](2026-09-10-public-package-manifest.md) | 中文
+
+## 问题
+
+插件作者需要从统一的公共导入路径获取 npm 身份、运行时要求和 DSH 声明。内部镜像打包、Session 目录和生成的代理元数据不定义社区插件扩展点。将这些字段一起暴露，会让外部作者误以为内部机制也可供使用。
+
+## 决策
+
+[`DshPackageManifest`](../../../../packages/util/package-manifest/src/types.ts) 描述 DSH 使用的 package.json 字段，其中 `name` 和 `version` 必填。其可选的 `dsh` 成员使用 `DshManifest` 描述公共组合与作者元数据。该类型只选取所需 npm 字段，不是完整的 package.json schema（模式）。App-boot 通过 `Partial` 适配无需发布身份的本地 profile。
+
+运行时要求位于顶层 `engines`：`dsh`、`node` 和 `npm` 均为可选版本字符串，也允许其他 engine 名称。`dsh.manifestVersion` 标识声明格式 `1`；`dsh.categories` 承载自由发现标签，不限制包的组合。当前安装器和加载器不强制检查格式与 DSH 兼容性声明。
+
+镜像打包器拥有 `configTrees`，工作区目录生成器拥有 Session 迁移声明，app-boot 拥有生成的模块后备元数据。这些内部工具仍可读取既有磁盘字段，但公共 manifest 类型不暴露这些字段。此范围细化了[共享声明归属决策](2026-09-05-package-manifest-types.zh.md)，后者的包位置与依赖规则仍然有效。
+
+各消费方负责 JSON 解析、字段校验、默认值解析和运行时数据适配。接口不会校验已解析的 JSON。只有多个消费方需要相同校验或归一化时，helper 才属于共享包；重复属性访问的 getter 不提供共享策略。
+
+## 考虑过的替代方案
+
+**将内部元数据保留在公共声明中。** 仅限工作区的迁移目录和实验性镜像打包器，不会因为其元数据可被发现就提供公共插件行为。
+
+**将 DSH 兼容性放在 `dsh.engines` 下。** [VS Code](https://code.visualstudio.com/api/references/extension-manifest) 将宿主要求放在顶层 `engines.vscode`。顶层 `engines.dsh` 让作者在同一位置声明运行时要求；自定义键的检查仍由 DSH 负责。
+
+**仅用 peer dependency 声明宿主要求。** Peer dependency 约束已安装的 npm 包，包括 CLI 包 `@deepseek-ai/dsh`。插件位于独立 profile 项目时，它们无法标识当前运行的 DSH 进程。
+
+**通过统一的强制解析器解析所有领域。** 现有读取方消费不同字段子集，并各自拥有错误与默认值。合并它们会让客户端读取方校验无关的 profile 声明。公共类型保持独立于文件系统访问和解析策略。
+
+## 后果
+
+外部作者获得完整的包级声明和更小的 DSH 作者 API。已移除内部类型的消费方必须使用各自负责的实现。打包器与仓库目录不再依赖公共声明包；app-boot 保留生产依赖，因为其发布的 profile 类型引用该包。
+
+编译器和构建后的 NodeNext 导入检查验证包身份必填、部分 profile、顶层 engine 声明，以及公共 API 不含内部字段。现有 profile、打包器和 Session 目录测试继续覆盖其接受的文件与畸形声明。Session 格式、插件加载规则和模型可见行为均不改变。

 ### Profiles
 
-Import profile and bundle declaration types from [`@deepseek-ai/dsh-package-manifest`](../../util/package-manifest/README.md). App-boot owns profile loading, JSON validation, and resolved runtime data.
+Import profile and bundle declaration types from [`@deepseek-ai/dsh-package-manifest`](../../util/package-manifest/README.md). App-boot adapts `DshPackageManifest` to `ProfileManifest` with optional package identity because local profiles need no published version. App-boot owns profile loading, JSON validation, and resolved runtime data.
 
 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 --profile <name> --from-default-profile <template>` creates a custom profile at a new non-shipped name from one shipped template, while `dsh plugin` initializes a base-backed profile and manages its installed bundles. A missing bundle or one without a patch declaration fails startup loudly. Application-owned npm projects, such as Electron's reserved Desktop profile, use `loadProfileDirectory` to load an already initialized directory without exposing it through CLI profile lookup.

 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 --profile <name> --from-default-profile <template>` 从一个随附模板，在新的非内置名称处创建自定义 profile；`dsh plugin` 则初始化以 base 为基础的 profile，并管理其中安装的 bundle。缺失 bundle 或未声明 patch 的 bundle 会让启动明确失败。由应用持有的 npm 项目（例如 Electron 保留的 Desktop profile）通过 `loadProfileDirectory` 加载已经初始化的目录，而不会将它暴露给 CLI profile 查找。

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.

 ### Explicit deliveries
 
-The Web `standard`, `ptc`, and `cordis` presets expose `present` for final files accessible through the Session filesystem, including files created through Bash. Call it with `files: [{ path, description? }]` after creating the files. The [present tool](../../fs/tool-present/README.md) owns file-count limits and Session declarations. The closing turn shows one delivery as a full-width card and multiple deliveries in a grid of at most two cards per row. A list longer than four files starts collapsed and provides a control that reveals or hides the complete list. Each card uses the shared `FileTypeIcon` and shows the basename and description, or the file type when no description exists; a trailing parenthesized suffix in the description is omitted, and hovering the card replaces that line with the Sidebar-preview action. Clicking the card or the left side of its split Open control previews the file in the right Sidebar. The chevron opens the standard menu for the Host default application plus Show in Finder on macOS, Show in File Explorer on Windows and WSL, or Open containing folder through the default Linux file manager. Matching inline-code references open the same source files without starting a browser download. Repeated declaration of a path selects its latest description before the closing reply.

Repeated declaration of a path selects its latest description before the closing reply.
 
 The `present` tool row shows running, delivered, failed, or interrupted status; expanding a settled row reveals its recorded result. The collapsible card grid retains every delivered file. Both menu actions share pending state and show progress, acknowledgement, or an action-specific retryable error. Desktop information is read when delivery cards appear and invalidated on connection replacement; responses from a replaced connection cannot publish metadata. Selecting a native menu action returns keyboard focus to the available Sidebar Open button. Pending actions close the menu until another explicit gesture. A missing desktop disables the Open menu; a failed desktop-information read offers Retry. It requires a desktop and a suitable default application on the serving Host; a remote browser does not open applications on its own device.

+# Agent Note: Composer reference previews
+
+Status: implemented
+
+English | [中文](2026-09-10-composer-reference-previews.zh.md)
+
+## Problem
+
+Users need to inspect referenced files and skill instructions while composing a message and after sending it. File chips and editable slash tokens have different editing semantics, but both need recognizable preview gestures without changing what the next prompt sends.
+
+## Decision
+
+The [input-trigger source](../../../../packages/client/ui-input-trigger/README.md) owns optional reference activation. The editor routes atomic references by their source identity and editable tokens through the current source lexicon. File and skill sources open the existing right Sidebar file resource in the composing Session. Skill discovery retains the winning provider's optional instruction-file path, avoiding body loads and guesses based on skill names or directory conventions.
+
+The [composer](../../../../packages/client/ui-conversation/README.md) shares reference hover styles while preserving atomic file chips and editable `/name` text. Clicking does not serialize or submit the draft. Invalid chips, selection gestures, and unavailable source targets retain editor handling; virtual skills remain invocable without a file preview.
+
+Sent message bubbles retain their logged skill-invocation evidence for decoration. The [Chat target](../../../../packages/client/ui-chat/README.md) opens file paths in the viewed Session and routes loaded skill names through that Session's source. The shared user-text primitive renders these references as buttons with the existing prose file-link hover and focus style; it leaves session, directory, and command references inert.
+
+## Alternatives considered
+
+**Turning skill tokens into file chips** would change editing, clipboard, and prompt semantics to solve a presentation task. The existing editable token already identifies a skill through its source lexicon.
+
+**Resolving file and skill formats inside the composer** would couple the editor to provider catalog policy and preview services. Source-owned activation keeps those dependencies with the plugins that already own reference discovery.
+
+**Loading each skill body during discovery** would add work and provider side effects before the user requests a preview. Optional path metadata is sufficient for filesystem skills and preserves virtual providers.
+
+## Consequences
+
+Preview paths are transient discovery data, never added to Session messages. The skill plugin invalidates them with its existing per-Session catalog. Sidebar resource readers retain responsibility for current contents, missing-file errors, and access policy. The [workspace source-file decision](2026-09-08-present-workspace-source-files.md) remains the owner of delivered-file behavior; composer previews do not supersede it.
+
+Focused tests cover source routing, disposal, invalidation, quoted paths, selection, and unchanged draft text. The real Web composition exercises both previews, equal hover backgrounds, and deletion after opening; owner-local expected output records the skill document and a sent message. A replayed skill-invocation turn verifies both sent references after reloading history.

+# Agent Note: 输入框引用预览
+
+Status: implemented
+
+[English](2026-09-10-composer-reference-previews.md) | 中文
+
+## Problem
+
+用户需要在编写消息时和发送后查看引用文件和 skill 指令。文件标签与可编辑的斜杠文本具有不同的编辑语义，但都需要明确的预览手势，且不能改变下一条提示发送的内容。
+
+## Decision
+
+[输入触发来源](../../../../packages/client/ui-input-trigger/README.zh.md)负责可选的引用激活。编辑器按来源身份路由原子引用，按来源当前词表路由可编辑文本。文件和 skill 来源在编写消息的 Session 中打开现有右侧栏文件资源。Skill 发现保留胜出提供方可选的指令文件路径，避免加载正文或根据 skill 名称、目录惯例猜测路径。
+
+[输入框](../../../../packages/client/ui-conversation/README.zh.md)共用引用悬停样式，同时保留原子文件标签和可编辑的 `/name` 文本。点击不序列化或提交草稿。无效标签、选择手势及不可用的来源目标仍由编辑器处理；虚拟 skill 仍可调用，但没有文件预览。
+
+已发送消息的气泡保留日志中的 skill 调用证据作为装饰依据。[Chat 目标](../../../../packages/client/ui-chat/README.zh.md)在当前查看的 Session 中打开文件路径，并通过该 Session 的来源路由已加载的 skill 名称。共享用户文本组件将这些引用渲染为按钮，复用现有正文文件链接的悬停和聚焦样式；会话、目录和命令引用不提供导航。
+
+## Alternatives considered
+
+**将 skill 文本转换为文件标签**会为了展示需求而改变编辑、剪贴板和提示语义。现有可编辑文本已经能够通过来源词表标识 skill。
+
+**在输入框内解析文件和 skill 格式**会让编辑器依赖提供方目录策略及预览服务。由来源负责激活，使这些依赖留在已经负责引用发现的插件中。
+
+**发现时加载每个 skill 的正文**会在用户请求预览之前增加工作和提供方副作用。可选路径元数据足以支持文件系统 skill，并保留虚拟提供方。
+
+## Consequences
+
+预览路径是临时发现数据，不会加入 Session 消息。Skill 插件使用现有的按 Session 缓存机制使路径失效。侧栏资源读取器继续负责当前内容、文件缺失错误和访问策略。[工作区源文件决策](2026-09-08-present-workspace-source-files.zh.md)仍负责交付文件行为；输入框预览不取代该决策。
+
+针对性测试覆盖来源路由、释放、缓存失效、带引号路径、文本选择和草稿不变。真实 Web 组合验证两种预览、一致的悬停背景及打开后的删除操作；其所属的预期输出记录 skill 文档及已发送消息。回放的 skill 调用轮次验证刷新历史后两种已发送引用仍可预览。

 The Session object also carries local submission echoes: `session.beginSubmission` inserts one into `SessionSnapshot.pendingSubmissions` synchronously, before the caller serializes and prompts, so a conversation UI can show the message on the submit click's own frame. The echo stores ordered image previews and durable file references. Session derives its `transcript`, `queued`, or `steering` placement from the current running state and requested delivery mode, then retains that placement while serialization is in flight. The prompt's `requestId` is the correlation identity: the Host echoes it as the durable user source's `rpcId`, and queue occurrences project it as `SessionQueuedItem.rpcId`. An echo retires one animation frame after its durable event or queue occurrence is observed, immediately when its identified prompt fails or is abandoned, and as failed on disposal. Each retirement fires `onRetire` exactly once; an observed retirement includes the ordered durable attachment references so the composer can release successful cards while preserving failed drafts. Echoes are Client memory only; reload and reconnect rebuild the conversation from durable events alone.
 
 
+The user-invocable `skills/list` metadata includes the winning provider’s optional instruction-file `path`. The composer can preview that file without loading every skill body or activating a cold Agent.

 Disabled Send and Stop buttons suppress their tooltips, including a Stop button that becomes a disabled Send button when the turn ends. While a normal composer is running, its primary pointer action remains Stop when the draft is empty or input is unavailable. Actionable text or attachments switch the same seat to Send; clearing or successfully submitting the draft restores Stop. The busy-Enter setting selects the Queue or Steer delivery for ordinary Sessions and continuable children, and the running Send button delivers through the same mode plain Enter resolves to; while it is enabled (no upload pending) over a plain message draft its label names that mode (Queue message or Steer message), so the setting governs Enter and the button together while Cmd/Ctrl+Enter still uses the other mode, and idle sessions, empty drafts, and `/` command lines keep the plain Send label ([decision](../../../.agents/notes/implemented/bug-fix/2026-09-04-busy-send-button-follows-enter-setting.md)). Their QueueDock rows share Edit, Remove, and Steer, and an empty draft shares the steer-all chord. One-shot children remain read-only. Plan mode and active goals do not change attachment intake. Continuable children keep separate Send and Stop actions but expose no paperclip, paste, or drop intake; if their parent is offline, Send and the composer gestures lock while QueueDock controls for the live inbox remain available ([decisions](../../../.agents/notes/archived/bug-fix/2026-08-20-running-draft-primary-send.md), [inbox controls](../../../.agents/notes/implemented/feature/2026-08-27-continuable-subagent-human-inbox-control.md)).
 
+File chips and editable skill references share a whole-reference hover background. A single click delegates preview opening to the registered reference source; double-click and text-selection gestures retain editor handling. Previewing does not change the draft, its clipboard projection, or submission.

 The composer surface keeps focus while the menu is open: rows pick on mousedown, the highlight rides `aria-activedescendant`, and a pointer press outside both the menu and the composer card dismisses it. Space and Enter adjudication polls the optional `matchSpace`/`matchEnter` hooks in registration order; the first non-undefined answer wins, and a source can refuse a submission it cannot consume whole. Tab acts on the highlighted completion: a candidate declaring `drill: true` routes through `onPick` with `action: 'drill'`, while an ordinary candidate settles through `action: 'pick'`; without a highlight, Tab passes untouched so native focus traversal survives. A drillable row's trailing chevron exposes the same second verb to pointer users. A source implementing the optional `header` hook additionally publishes crumbs above its group: the pipeline re-polls it on every hit with the live query and whether a drill, rather than typing, produced it, and a crumb pick routes back through `onPick` with `action: 'drill'`.
 
+A source may implement `openReference(session, reference)` to open a draft reference without submitting it. Chips route by source name; editable tokens route through the current source lexicon. Returning `false`, a missing source, or a disposed controller leaves the editor gesture unchanged.

A load or decode failure replaces the image with its authored alt text, or the original destination when alt is empty. Changing the image source permits a fresh load. While a reply streams, it freezes completed blocks, advances a top-level open fence by completed lines, and highlights that fence from saved Shiki grammar state. Completed token lines enter fixed-size React groups, so later chunks reconcile only the growing group; an unchanged fence retains that DOM when the final full parse resolves cross-document syntax. `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 `projectUserText` projects sent user text into inline plain runs and reference chips for the message bubble and queue rows.

Completed token lines enter fixed-size React groups, so later chunks reconcile only the growing group; an unchanged fence retains that DOM when the final full parse resolves cross-document syntax. `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 `projectUserText` projects sent user text into inline plain runs and reference chips for the message bubble and queue rows. When supplied with `UserTextReferences`, file and skill references become keyboard-accessible preview buttons using the same hover and focus styling as prose file links; text selection does not open previews.

 A collapsed row renders the skill glyph, `Skill` title, and requested skill name; 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 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 stays stable when installed skills or their descriptions change.

 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.
 
+Skill summaries retain the winning provider’s optional instruction-file `path` for discovery consumers that offer file previews. Listing still reads no skill body, and model-facing catalogs continue to select only their owned routing fields.

 Disabled Send and Stop buttons suppress their tooltips, including a Stop button that becomes a disabled Send button when the turn ends. While a normal composer is running, its primary pointer action remains Stop when the draft is empty or input is unavailable. Actionable text or attachments switch the same seat to Send; clearing or successfully submitting the draft restores Stop. The busy-Enter setting selects the Queue or Steer delivery for ordinary Sessions and continuable children, and the running Send button delivers through the same mode plain Enter resolves to; while it is enabled (no upload pending) over a plain message draft its label names that mode (Queue message or Steer message), so the setting governs Enter and the button together while Cmd/Ctrl+Enter still uses the other mode, and idle sessions, empty drafts, and `/` command lines keep the plain Send label ([decision](../../../.agents/notes/implemented/bug-fix/2026-09-04-busy-send-button-follows-enter-setting.md)). Their QueueDock rows share Edit, Remove, and Steer, and an empty draft shares the steer-all chord. One-shot children remain read-only. Plan mode and active goals do not change attachment intake. Continuable children keep separate Send and Stop actions but expose no paperclip, paste, or drop intake; if their parent is offline, Send and the composer gestures lock while QueueDock controls for the live inbox remain available ([decisions](../../../.agents/notes/archived/bug-fix/2026-08-20-running-draft-primary-send.md), [inbox controls](../../../.agents/notes/implemented/feature/2026-08-27-continuable-subagent-human-inbox-control.md)).

 [`DshPackageManifest`](../../../../packages/util/package-manifest/src/types.ts) describes the package.json fields DSH uses, with required `name` and `version`. Its optional `dsh` member uses `DshManifest` for public composition and author metadata. The type is a selected npm field set, not a complete package.json schema. App-boot adapts it with `Partial` for local profiles, which need no published identity.
 
-Runtime requirements live at top-level `engines`: `dsh`, `node`, and `npm` are optional version strings, and other engine names are allowed. `dsh.manifestVersion` identifies declaration format `1`; `dsh.categories` carries free-form discovery tags without restricting package composition. Format and DSH compatibility declarations are not enforced by current installers or loaders.

 The image packer owns `configTrees`, the workspace catalog generator owns Session migration declarations, and app-boot owns generated module-fallback metadata. Their existing on-disk keys remain readable by those internal tools, but the public manifest types do not expose them. This scope refines the [shared declaration ownership decision](2026-09-05-package-manifest-types.md), whose package placement and dependency rules remain active.

+# Agent Note: DeepSeek image-token estimator on the v41 calculator
+
+Status: implemented
+
+English | [中文](2026-09-10-deepseek-image-token-calculator-v41.zh.md)
+
+## Problem
+
+`deepSeekImageTokens()` in `llm-deepseek` ported the provider's published image-token calculator in its `v4` configuration: a 384×384 scale-up floor, a 384-token cap, an 8:1 width clamp, a grid layout that adds a row for odd row counts and parity corrections, and a pad-to-4 alignment charged at its worst case. The provider's Vision guide now documents a different projection for the current Flash model: images below roughly 544×544 total pixels scale up, larger images scale down to roughly 1300×1300 total pixels, and one image costs at most 1024 tokens. The published calculator carries this as a `v41` configuration and the docs page instantiates that one. The old port therefore underpriced every retained image, an 800×800 request image by 73 tokens, so automatic compaction on image-dense sessions triggered late.
+
+## Decision
+
+`image-tokens.ts` is rewritten as a verbatim port of the `v41` configuration. The constants are a 14px patch, 3:1 per-axis downsampling, a 544×544 total-pixel floor, and a 1024-token cap. The grid formula is `rows × (cols + 1) + 2` with no odd-row extra row, no parity correction, and no even-row trimming in the solver. There is no alignment pad, so the estimate is exact rather than a worst-case upper bound, and there is no aspect-ratio clamp, so extreme aspect ratios reach the cap through the solver's one-row and one-column branches. The over-budget path is a single closed-form solve followed by the published assertion; the decrementing retry loop existed only for the odd-row layout. The provider's fixpoint iteration over the projected dimensions is unchanged.
+
+The test vectors are re-pinned from the published calculator. The request-pricing tests, package README, and this note carry the new numbers; the pixel budget the harness applies before pricing (`DEFAULT_REQUEST_IMAGE_PIXEL_BUDGET`, 640,000 total pixels) and the catalog model ids are unchanged.
+
+## Alternatives considered
+
+**Keep both configurations and select by model id.** The provider states that requests to the retired `deepseek-v4-flash-vision-exp` id are served by the current Flash model, so no reachable route prices under the old configuration. Two configurations would keep dead branches and their tests alive.
+
+**Keep the generic class with the `isNLayout`, pad, and ratio-clamp switches.** A one-configuration port has fewer unreachable branches to exclude from coverage and states the shipped rule directly; a future provider revision changes this one module and its pinned vectors either way.
+
+**Raise the harness pixel budget in the same change.** The provider now accepts roughly 1300×1300 total pixels per image, so the harness's 640,000-pixel projection discards detail the model could use. That is a request-content change with its own snapshot impact, separate from pricing what is actually sent.
+
+## Consequences
+
+Retained request images price higher, so image-dense DeepSeek sessions compact earlier and closer to the provider's real pressure. Under the harness's 640,000-pixel projection the ceiling for one image is 422 tokens at 800×800 rather than 349. The estimate no longer carries a three-token conservative margin; provider usage remains the authoritative anchor once a request completes. Sessions replayed through `llm-replay` use their fixture's `imageRequestTokens` and are unaffected.

+# Agent Note: DeepSeek 图片 token 估算器改用 v41 计算器
+
+Status: implemented
+
+[English](2026-09-10-deepseek-image-token-calculator-v41.md) | 中文
+
+## 问题
+
+`llm-deepseek` 中的 `deepSeekImageTokens()` 移植的是提供方公开图片 token 计算器的 `v4` 配置：384×384 放大下限、384 token 上限、8:1 宽度钳制、奇数行数额外加一行并做奇偶校正的网格布局，以及按最坏情况计价的 pad-to-4 对齐。提供方的图像理解指南现在为当前 Flash 模型记录了另一套投影规则：总像素小于约 544×544 的图片放大，更大的图片缩小到约 1300×1300 总像素，单张图片最多 1024 token。公开计算器以 `v41` 配置承载这套规则，文档页实例化的也是它。旧移植因此对每张保留图片都估低，一张 800×800 的请求图片低估 73 token，图片密集会话的自动压缩触发过晚。
+
+## 决策
+
+`image-tokens.ts` 重写为 `v41` 配置的逐句移植。常量为 14px patch、每轴 3:1 降采样、544×544 总像素下限、1024 token 上限。网格公式为 `rows × (cols + 1) + 2`，没有奇数行额外行、没有奇偶校正、求解器也不再把行数截成偶数。没有对齐 pad，所以估算值是精确值而非最坏情况上界；没有宽高比钳制，所以极端长宽比会经求解器的单行和单列分支到达上限。超预算路径是一次闭式求解加上公开的断言；逐步递减的重试循环只服务于奇数行布局。提供方对投影尺寸的定点迭代保持不变。
+
+测试向量按公开计算器重新固定。request-pricing 测试、包 README 和本 note 使用新数字；harness 在定价前应用的像素预算（`DEFAULT_REQUEST_IMAGE_PIXEL_BUDGET`，640,000 总像素）和 catalog 模型 id 不变。
+
+## 备选方案
+
+**保留两套配置并按模型 id 选择。** 提供方说明发往已下线的 `deepseek-v4-flash-vision-exp` 的请求由当前 Flash 模型承接，所以没有可达路由会按旧配置计价。两套配置会保留死分支及其测试。
+
+**保留带 `isNLayout`、pad 和宽高比钳制开关的通用类。** 单配置移植需要从覆盖率中排除的不可达分支更少，并直接陈述已上线的规则；提供方未来再修订时，两种写法都只改这一个模块和它固定的向量。
+
+**在同一改动中提高 harness 像素预算。** 提供方现在每张图接受约 1300×1300 总像素，harness 的 640,000 像素投影会丢弃模型本可利用的细节。那是请求内容的改动，有自己的快照影响，与为实际发送内容计价是两件事。
+
+## 后果
+
+保留的请求图片计价更高，图片密集的 DeepSeek 会话会更早压缩，更接近提供方的真实压力。在 harness 的 640,000 像素投影下，单张图片的上限是 800×800 时的 422 token，而非 349。估算值不再带 3 token 的保守余量；请求完成后，提供方 usage 仍是权威锚点。经 `llm-replay` 回放的会话使用各自 fixture 的 `imageRequestTokens`，不受影响。

 #### Token effect
 
-Provider tokenization governs exact text and image-token input. The adapter declares per-route `imageRequestPricing`: it reproduces oldest-first image offload from durable byte lengths and prices each retained image at its projected dimensions with the published v4 vision accounting (14px patch grid, 3:1 downsampling, 384-token cap, worst-case alignment pad). This lets the token meter price image pressure before a request; 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. `totalTokens` is the exact `prompt_tokens + completion_tokens` aggregate and is omitted if a supplied `total_tokens` disagrees.

+Preview paths are transient discovery data, never added to Session messages. The skill plugin invalidates them with its existing per-Session catalog. An uncached click awaits the shared catalog fetch and retains its Session address; invalidation and disposal cancel pending previews. Filesystem providers publish resolved instruction paths while retaining discovered reload locators and resource bases. Sidebar resource readers retain responsibility for current contents, missing-file errors, and access policy. The [workspace source-file decision](2026-09-08-present-workspace-source-files.md) remains the owner of delivered-file behavior; composer previews do not supersede it.
 
 Focused tests cover source routing, disposal, invalidation, quoted paths, selection, and unchanged draft text. The real Web composition exercises both previews, equal hover backgrounds, and deletion after opening; owner-local expected output records the skill document and a sent message. A replayed skill-invocation turn verifies both sent references after reloading history.

 Disabled Send and Stop buttons suppress their tooltips, including a Stop button that becomes a disabled Send button when the turn ends. While a normal composer is running, its primary pointer action remains Stop when the draft is empty or input is unavailable. Actionable text or attachments switch the same seat to Send; clearing or successfully submitting the draft restores Stop. The busy-Enter setting selects the Queue or Steer delivery for ordinary Sessions and continuable children, and the running Send button delivers through the same mode plain Enter resolves to; while it is enabled (no upload pending) over a plain message draft its label names that mode (Queue message or Steer message), so the setting governs Enter and the button together while Cmd/Ctrl+Enter still uses the other mode, and idle sessions, empty drafts, and `/` command lines keep the plain Send label ([decision](../../../.agents/notes/implemented/bug-fix/2026-09-04-busy-send-button-follows-enter-setting.md)). Their QueueDock rows share Edit, Remove, and Steer, and an empty draft shares the steer-all chord. One-shot children remain read-only. Plan mode and active goals do not change attachment intake. Continuable children keep separate Send and Stop actions but expose no paperclip, paste, or drop intake; if their parent is offline, Send and the composer gestures lock while QueueDock controls for the live inbox remain available ([decisions](../../../.agents/notes/archived/bug-fix/2026-08-20-running-draft-primary-send.md), [inbox controls](../../../.agents/notes/implemented/feature/2026-08-27-continuable-subagent-human-inbox-control.md)).

 The composer surface keeps focus while the menu is open: rows pick on mousedown, the highlight rides `aria-activedescendant`, and a pointer press outside both the menu and the composer card dismisses it. Space and Enter adjudication polls the optional `matchSpace`/`matchEnter` hooks in registration order; the first non-undefined answer wins, and a source can refuse a submission it cannot consume whole. Tab acts on the highlighted completion: a candidate declaring `drill: true` routes through `onPick` with `action: 'drill'`, while an ordinary candidate settles through `action: 'pick'`; without a highlight, Tab passes untouched so native focus traversal survives. A drillable row's trailing chevron exposes the same second verb to pointer users. A source implementing the optional `header` hook additionally publishes crumbs above its group: the pipeline re-polls it on every hit with the live query and whether a drill, rather than typing, produced it, and a crumb pick routes back through `onPick` with `action: 'drill'`.

 ### Rendering agent output
 
-`MarkdownText` renders untrusted GFM and TeX math, blocks unsafe links and images, and can turn resolved file mentions into explicit controls. When the owner passes a `pathImages` vocabulary, image destinations that are local media paths rewrite to displayable URLs on settled renders only (the same streaming gate as file mentions); without a vocabulary, local destinations remain inert alt text. A load or decode failure replaces the image with its authored alt text, or the original destination when alt is empty. Changing the image source permits a fresh load. While a reply streams, it freezes completed blocks, advances a top-level open fence by completed lines, and highlights that fence from saved Shiki grammar state. Completed token lines enter fixed-size React groups, so later chunks reconcile only the growing group; an unchanged fence retains that DOM when the final full parse resolves cross-document syntax. `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 `projectUserText` projects sent user text into inline plain runs and reference chips for the message bubble and queue rows. When supplied with `UserTextReferences`, file and skill references become keyboard-accessible preview buttons using the same hover and focus styling as prose file links; text selection does not open previews.

 A collapsed row renders the skill glyph, `Skill` title, and requested skill name; 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 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 stays stable when installed skills or their descriptions change.

+Hovering over `/name` highlights the entire reference. Clicking a known skill opens its provider-supplied `SKILL.md` path in the right Sidebar while keeping the token editable. An uncached click shares the per-Session catalog fetch and opens when it completes, retaining the clicked Session address. Preset changes, connection resets, and plugin disposal cancel pending previews; a later click fetches the current catalog again. Skills without a file path remain invocable but have no file preview.

 `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.
 
+Catalog entries and loaded skills expose the resolved instruction-file path, so symlinked directories and flat files can open as regular-file previews. Reload locators and resource bases retain the discovered paths, including symlinks.
+
 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.

 ## Problem
 
-`deepSeekImageTokens()` in `llm-deepseek` ported the provider's published image-token calculator in its `v4` configuration: a 384×384 scale-up floor, a 384-token cap, an 8:1 width clamp, a grid layout that adds a row for odd row counts and parity corrections, and a pad-to-4 alignment charged at its worst case. The provider's Vision guide now documents a different projection for the current Flash model: images below roughly 544×544 total pixels scale up, larger images scale down to roughly 1300×1300 total pixels, and one image costs at most 1024 tokens. The published calculator carries this as a `v41` configuration and the docs page instantiates that one. The old port therefore underpriced every retained image, an 800×800 request image by 73 tokens, so automatic compaction on image-dense sessions triggered late.

-Retained request images price higher, so image-dense DeepSeek sessions compact earlier and closer to the provider's real pressure.

Compaction pressure changes with the retained image dimensions. The 640,000-pixel budget does not imply a 422-token ceiling: an 8192×1 image stays within that pixel budget and costs 1024 tokens.

 Supported Linux ordinary and PTY launches and Windows ordinary launches retain descendants through process-group escape and direct-parent exit, while direct target results remain independent from range quiescence. The cost is a per-spawn Linux manager check and scope/request or Windows runner/IPC/Job lifecycle, plus explicit failure when the selected owner cannot prove settlement.

 Normal disposal terminates every running managed range and terminal session and awaits quiescence. During a JavaScript-observable host exit — direct `process.exit()`, default uncaught exceptions, default unhandled rejections — synchronous finalization asks a Linux scope to kill its members, kills each Windows runner so its sole Job handle closes, and uses the existing PGID, `taskkill`, or captured-identity operation for fallbacks. It creates no promises or timers and does not claim quiescence. The same exit removes the private per-process spill directory when it holds no completed spill file; completed spill files remain as full-output recovery artifacts until an external cleanup. Unhandled `SIGTERM`/`SIGINT`/`SIGHUP`, `SIGKILL`, fatal OOM, native crashes, and power loss need an external supervisor.
 
+Linux ordinary and terminal cancellation preserves the observed termination signal even before the bootstrap consumes its launch request. An unconsumed request still reports startup failure when no matching termination was requested; a recorded pre-exec error always takes precedence. `waitForExit()` independently proves the scope empty.
+
 ### What can go wrong
 
 An executable that cannot be resolved fails loud with a stable error. `done` rejects when spawn or provider failure prevents a direct outcome, and that rejection does not prove whether target execution began. `waitForExit()` rejects if the selected owner can no longer prove its range empty, and cleanup still attempts termination. A read past the retained tail is `lossy` and points at the spill file when one exists. A fallback process group or observed terminal session can miss a descendant that escapes before observation — see the limitations below.

+Linux 普通进程和终端进程即使在 bootstrap 消费启动请求前被取消，也会保留实际观察到的终止信号。如果没有请求对应的终止信号，未消费的请求仍会报启动失败；已记录的 pre-exec 错误始终优先。`waitForExit()` 独立证明 scope 已为空。
+
 ### 可能出错的地方
 
 无法解析的可执行文件会明确报出稳定错误。当 spawn 或提供方故障使 direct outcome 无法产生时，`done` 会 reject；该 rejection 不能证明 target 是否已经开始执行。若所选 owner 无法再证明其范围为空，`waitForExit()` 会 reject，清理仍会尝试终止。越过保留尾部的读取是 `lossy` 的，并在 spill 文件存在时指向它。fallback 进程组或已观察终端 session 可能遗漏在观察前逃逸的后代——见下文限制。

Subject: [PATCH 162/164] feat(web): gate agent preset selection behind a
 setting (#3870)

* feat(web): gate agent preset selection behind a setting

* refactor(web): trim preset visibility diff

* refactor(web): simplify agent preset selection policy

* test(web): cover agent preset policy branches

* refactor(web): tighten agent preset policy flow

* fix(web): preserve preset default across picker toggle

* docs(web): align agent preset picker docs with the blank-task sync

Both picker transitions carry the effective default to the current blank task; started and historical sessions keep their labels, compositions, and recorded history. The Host README states the client rule and links the Web switch; the Agent Note English side matches the Chinese at line 64. Three i18n pairs re-recorded; doc-sync 34/34.

* refactor(web): simplify agent preset picker policy

* test(web): cover preset policy recovery

* docs(web): clarify disabled preset default copy

* fix(web): reconcile preset policy races

* fix(web): satisfy preset load lint

* fix(web): serialize preset roster refreshes

* fix(web): release preset refresh before notifying waiters

 Mounting is per-session by default. Measured cost for a twelve-row composition is ~3ms and ~600KB per session, so isolation is the cheaper default than any sharing scheme, and a preset authored by a user or by an agent then has the smallest possible blast radius. A preset that genuinely owns an expensive singleton opts into sharing with Cordis's own `isolate` vocabulary: a named realm label is process-global, so two subtrees naming the same label resolve one instance.
 
-Which preset an unnamed session gets is a user setting (`agent-presets.default`) layered over the composition's own `default`, which becomes the `base`. Both layers are needed: the composition value is what a deployment ships and must keep working with no settings provider at all, and the setting is what a person changes without editing a `cordis.yml` they may not own.
+The `agent-presets` user-settings namespace carries `modeSelectionEnabled` and `default`. `modeSelectionEnabled` defaults to `true`: the existing new-session picker remains present and an unnamed session resolves to the saved user `default`, or the composition's deployment `default` when none exists. The Web Settings toggle changes only that policy: disabling selection temporarily uses the deployment default, while re-enabling it restores the saved user `default`. This is a deliberate exception to the ordinary user-over-composition settings precedence established in [#1539](https://github.com/deepseek-harness/deepseek-harness/pull/1539): hiding the chooser disables the user's mode-selection policy without deleting its saved value. The Host policy governs every later session whose caller omits a preset; explicitly named presets and existing sessions remain unchanged. The composition value also keeps the package working with no settings provider, while an enabled user override changes later sessions without editing a deployment-owned `cordis.yml`.
 
 ## Consequences
 
-**The effective default is read per resolution, never snapshotted.** A cached value would need a `watch` subscription and a reload path to stay honest, and the resolved scope already re-reads a hot-reloaded document. Reading through is also what makes the boundary correct rather than merely cheap: the new value applies to the next session created, and every running session keeps the composition it was built from. That invariant is the same one the session log enforces from the other side — the header records the id a session was CREATED with and an `agent-preset/selected` event records any later blank-session switch, so a reader resolves the pair (`resolveSessionPreset`) and never the header alone: a resume rebuilds the composition its history was produced under rather than the deployment default at resume time, a cold transcript's presenters resolve in that composition's layer, and the gateway rejects an attempt to adopt a live session under a preset other than the one it currently runs. A snapshot would make the two disagree at exactly the moment the setting changes.
+**The effective default is read per resolution, never snapshotted.** A cached value would need a `watch` subscription and a reload path to stay honest, and the resolved scope already re-reads a hot-reloaded document. The Host setting itself applies when an unnamed session is resolved afterwards. An explicit Web Settings action additionally routes its accepted effective default through the existing blank-session selection path only when the captured session id is still current and blank; it never recomposes a running session or rewrites that session's history. The session log enforces the same invariant from the other side — the header records the id a session was CREATED with and an `agent-preset/selected` event records any later blank-session switch, so a reader resolves the pair (`resolveSessionPreset`) and never the header alone: a resume rebuilds the composition its history was produced under rather than the deployment default at resume time, a cold transcript's presenters resolve in that composition's layer, and the gateway rejects an attempt to adopt a live session under a preset other than the one it currently runs.

 **A directly-plugged subtree is invisible to the boot audit.** It never links itself to an `Entry`, so it is absent from `ctx.loader.entries()` and `assertEntriesActivated` cannot see it. The mount audits its own rows instead, reading the tree through an `Include` subclass that publishes it.
 
@@ -61,11 +61,11 @@ Which preset an unnamed session gets is a user setting (`agent-presets.default`)
 
 **A preset's package names must resolve from the harness, not from the preset.** `EntryTree.import()` resolves a row against its own tree's `baseUrl`, which `Include` sets to the composition's directory. That is right for a relative specifier and fatal for a package name: a locally authored preset lives under the user's home, where Node's upward `node_modules` walk never reaches the installed harness, so every `@deepseek-ai/dsh-*` row fails to import and the whole preset is unmountable. The shipped presets hid this — they sit inside the install. The mount records the host composition's base before plugging the subtree and sends bare specifiers there, leaving relative paths resolving from the preset so its own files still travel with it. The real-composition test writing a preset into a temp root is what found it.
 
-**The preset id is model-visible and must be logged.** It determines the tool set and prompt, so a resumed session has to restore the same composition; recording it is a session fact, not runtime state. It rides the session header beside `cwd`, and the summary carries it so a picker shows what a session actually runs rather than the deployment's current default.

It rides the session header beside `cwd`, and the summary carries it so the client surfaces show what a session actually runs rather than the deployment's current default.
 
 **A durable header field is not durable until the provider writes it.** `agentPreset` landed on `SessionHeader` with the right rationale and the JSONL provider omitted it; the derived query index also maps header fields explicitly, so a resumed Session came back with no preset and the surfaces that name it fell silent. `summarizeCold` had the same form — it hand-built the cold list row instead of reusing the shared projection. A field declared durable needs a test that crosses a real store, not only the type that declares it.
 
-**The choice belongs to the screen where it still works.** The composer seat spent almost its whole life disabled, since the preset is fixed once a turn has run. It moved to the new-session screen beside the workspace picker, where the pick is *staged*: that screen precedes the session it applies to, and the stage lands when a session becomes current and is still blank — covering both the session a workspace connect creates and the blank one it reuses, which riding `sessions.create` would miss. It is spent on first use, matching the workspace picker beside it. What a running session runs is then a read-only label in its header: a control there would promise a switch the host refuses outright.
+**The choice belongs to the screen where it still works.** The control lives on the new-session screen beside the workspace picker, is present under the default-on Host policy, and disappears only after `modeSelectionEnabled` is disabled. Its pick is *staged*: that screen precedes the session it applies to, and the stage lands when a session becomes current and is still blank — covering both the session a workspace connect creates and the blank one it reuses, which riding `sessions.create` would miss. It is spent on first use, matching the workspace picker beside it; hiding the picker discards a stage that has not reached a session and returns the current blank session to the deployment default through the same selection path. What a running or historical session runs remains a read-only label in its header: a control there would promise a switch the host refuses outright.
 
 **A preset multiplies a cost the host was already paying: nothing disposes an agent.** Measured against the shipped compositions with `--expose-gc`, one live agent holds ~0.17 MB on `minimal` and ~1.31 MB on `standard`/`cordis`, mounting in ~38 ms and ~135 ms; the first agent of a process costs ~7 MB more as Node imports the modules, which every later mount then shares. Growth is strictly linear — 10, 30 and 50 agents give the same per-agent delta — and disposal reclaims essentially all of it (50 `standard` agents held 57.8 MB and returned it). So the object graph does not leak; the lifecycle does. `ApiSessionAgentController` discards the `AgentHandle` returned by the registry, `archiveSession` only edits the workspace registry, `AgentRegistry` has no eviction, and the sole disposal site in the host is the JSON-RPC server's own shutdown. A web host therefore retains every session it has touched, at ~1.3 MB each once presets are composed rather than ~0.2 MB before. Note that pruning the mount registry does not help here: it drops records whose fiber `uid` has cleared, and an agent that never dies never clears one.

 挂载默认按会话进行。实测一份十二行组装每会话约 3ms、约 600KB，因此隔离比任何共享方案都更划算；而由用户或 agent 写出的 preset 也因此拥有尽可能小的影响面。确实自带昂贵单例的 preset，可以用 Cordis 自身的 `isolate` 词汇显式选择共享：命名 realm 的 label 是进程级全局的，因此两棵子树只要写同一个 label 就解析到同一个实例。
 
-未指名 preset 的会话拿到哪一个，是一项用户设置（`agent-presets.default`），叠在组装自身的 `default` 之上——后者成为 `base`。两层都需要：组装里的值是部署交付的东西，在完全没有 settings 提供方时也必须照常工作；而设置是让人不必去改一份可能并不属于自己的 `cordis.yml` 就能调整的东西。
+`agent-presets` 用户设置命名空间同时携带 `modeSelectionEnabled` 与 `default`。`modeSelectionEnabled` 默认为 `true`：既有的新建会话选择器保持显示；未指名会话会解析到已保存的用户 `default`，尚未保存时则使用组装中 `default` 指定的部署默认值。Web 设置开关只改变该策略：关闭选择时临时使用部署默认值，再次开启时恢复已保存的用户 `default`。这是对 [#1539](https://github.com/deepseek-harness/deepseek-harness/pull/1539) 所确立“用户值覆盖组装值”这一普通 settings 优先级的有意例外：隐藏选择器会停用用户的模式选择策略，但不会删除其保存值。该 Host 策略适用于此后所有未显式指定 preset 的会话；显式指定及既有会话不受影响。组装值还使本包在没有 settings 提供方时照常工作；选择器开启后，用户可覆盖默认值来改变后续会话，而无需编辑部署所拥有的 `cordis.yml`。

-**有效默认值在每次解析时读取，绝不保存快照。** 缓存下来就需要一个 `watch` 订阅和一条重载路径才能保持诚实，而解析后的 scope 本来就会重读热重载过的文档。读穿也不只是省事，它让边界本身是对的：新值作用于**下一个新建的会话**，每个运行中的会话保持它被构建时的那份组装。这条不变量正是 session 日志从另一侧执行的同一条——header 记录会话**创建时**的 id，此后空白期的任何切换由 `agent-preset/selected` 事件记录，因此读取方解析的是两者之和（`resolveSessionPreset`）、绝不单看 header：恢复重建的是其历史所产出的那份组装而不是恢复时的部署默认值，冷读记录的 presenter 在那份组装的层里解析，网关也会拒绝把一个活着的会话收编到它当前运行的 preset 以外的 preset 之下。快照会让两者恰好在设置改变的那一刻各说各话。

 **preset 的包名必须从 harness 解析，而非从 preset 解析。** `EntryTree.import()` 按行所属树的 `baseUrl` 解析，而 `Include` 把它设为组装文件所在的目录。这对相对标识符是对的，对包名却是致命的：本地创作的 preset 位于用户主目录之下，Node 向上查找 `node_modules` 永远够不到已安装的 harness，因此每一个 `@deepseek-ai/dsh-*` 行都会导入失败，整个 preset 无法挂载。随部署提供的 preset 掩盖了这一点——它们本就在安装目录之内。挂载在插入子树之前先记录宿主组装的基址，并把裸标识符送往那里，同时让相对路径继续从 preset 解析，使它自带的文件仍随它一同迁移。发现它的正是那个把 preset 写入临时根目录的真实组装测试。

 **preset 放大的是宿主本来就在付的代价：没有任何东西会 dispose 一个 agent。** 用 `--expose-gc` 对随附组装实测：一个存活的 agent 在 `minimal` 上约占 0.17 MB、在 `standard`/`cordis` 上约 1.31 MB，挂载耗时分别约 38 ms 与 135 ms；进程里第一个 agent 另需约 7 MB，那是 Node 首次 import 模块的一次性成本，此后每次挂载共享。增长严格线性——10、30、50 个的单个增量一致——且 dispose 后基本全额回收（50 个 `standard` 占住 57.8 MB，释放后全部归还）。所以对象图并不泄漏，缺的是生命周期。`ApiSessionAgentController` 会丢弃注册表返回的 `AgentHandle`，`archiveSession` 只改工作区注册表，`AgentRegistry` 没有驱逐机制，而宿主里唯一一处 dispose 是 JSON-RPC 服务器自身的关停。于是一个 web 宿主会留住它接触过的每一个会话，组装 preset 之后每个约 1.3 MB，而在此之前约 0.2 MB。注意：剪枝挂载注册表在这里没有用——它丢弃的是 fiber `uid` 已清空的记录，而永不死亡的 agent 永远不会清空它。

 ## Summary
 
-Use this package to choose the agent preset for a new Web GUI session, see the active preset in the session header, and manage available presets in Settings. A preset is fixed when a session is created, so changing the selection or default affects only later sessions. If the deployment provides no presets, these controls stay hidden and every session uses the host composition.
+Use this package to choose the agent preset for a new Web GUI session, see the active preset in the session header, and manage available presets in Settings. The Agent mode picker is shown by default; Settings can hide it without changing running or historical sessions. A preset is fixed when a session is created, so changing the selection or default affects only later sessions.

 ## Use this package
 
-Mount this plugin alongside the settings and conversation packages; the preset surfaces then appear where their slots render. The new-session chip opens on the deployment default and stages a pick that lands on the next blank session; the stage is spent on first use, so the following new session opens on the default again.
+Mount this plugin alongside the settings and conversation packages; the management section then shows a visibility switch that is on by default. While it is off, the new-session chip is absent and the Host composes an unnamed session from the deployment default (`standard` in the shipped Web bundle). Turning it on restores the saved user default, or uses the deployment default when none has been saved, and carries that default to the current blank task; a chip pick itself is staged only once for the next blank session. Turning the picker off again returns the current blank task to the deployment default the same way and discards an unconsumed stage; started and historical sessions keep their labels, compositions, and recorded history.
 
 ### Managing the roster
 
-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. The card face still shows the preset's own description — a chooser cannot act on a package specifier there — and the host's reason rides the badge as a tooltip, plus a visually hidden alert that carries it to assistive technology, which a disabled card body cannot.
+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 visibility switch changes only whether the saved user default is active: the Host uses the deployment default while hidden and restores the saved default when the picker is shown again. While the picker is enabled, choosing a healthy non-default card writes a new user default for later sessions; if the current new-task surface already reuses a blank session, that explicit Settings action carries the same preset to that exact blank session through the existing selection path. Started and historical sessions remain unchanged. The switch is disabled while saving, and a failed write keeps the prior preference and shows an error. Hiding the picker disables default selection and the Creator launch but leaves roster viewing, copying, location, and deletion available. 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.

-The display options come from one `agentPresets/list` call — the roster already reports which id a session with no explicit choice gets, so no surface introspects the settings schema — and the default write, the settings section's make-default action, targets the `agent-presets` settings namespace's `default` field, which is what the host resolves at creation. The settings section queries `settings.canOpenAgentPresetDirectory()` when it first loads and joins that result with the roster; a failed query removes only the native-open affordance. 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. A refusal announces itself as a transient banner over the composer column, because the chip's label has already reverted and a preset the host refuses to mount is one discovery reported healthy — its roster card carries no reason to go back and read. Only a pick a person just made is announced; the applier that runs when a session becomes current is not. [`dsh-client-connection`](../connection/README.md) authenticates `agentPresets/read`, `agentPresets/copy`, `settings/openAgentPresetDirectory`, `agentPresets/deletePreset`, `agentPresets/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, delete, and the settings-owned directory opener manage the roster and drive the host desktop. The section re-reads on its own actions, `settings/document-updated`, and `connection/reset`, because composition files are edited outside the browser and nothing on the wire announces a file change.
+The settings section writes the Host's existing `agent-presets` namespace through `settings.update`. Its visibility switch sets only `modeSelectionEnabled`, and its make-default action writes `default` only while the picker is shown. After either write, the Host roster supplies the effective default, and the chip controller's `agentPresets/select` path carries it to the same still-blank session; that path is the only session-mutation API these surfaces use. Display options and Host-effective visibility come from `agentPresets/list` — the roster already marks the effective Host default and carries `modeSelectionEnabled`, so a non-loopback read-only client stays consistent without introspecting the settings schema. The settings section queries `settings.canOpenAgentPresetDirectory()` when it first loads and joins that result with the roster; a failed query removes only the native-open affordance. The new-session chip renders only while `modeSelectionEnabled` is true; hiding it drops a pending stage and local menu or refusal state, while the header label remains registered and reads each session's recorded preset. 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.

 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 `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:
+The required `default` config sets the deployment default. When a settings provider is composed, this plugin registers the `agent-presets` namespace with `{ default: config.default, modeSelectionEnabled: true }` as its base, so the existing new-session picker remains visible unless a user turns it off. The Host reads both fields on every default resolution: while `modeSelectionEnabled` is false, an omitted preset resolves to `config.default` even if the user document retains another `default`; while it is true, a user default may override the deployment value:
 
 ```yaml
 agent-presets:
+  modeSelectionEnabled: true
   default: minimal
 ```
 
-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.
+A client shows or hides selection by writing only `modeSelectionEnabled`; the [Web GUI settings switch](../../client/ui-agent-preset/README.md) does exactly that. The deployment default governs while selection is hidden; re-enabling it restores the saved user `default`, or keeps the deployment default when none has been saved. While mode selection stays enabled, choosing a default writes a user override for sessions created later. Because the Host owns the policy, it applies to every subsequently created session whose caller omits a preset, including Web, CLI, SDK, and headless callers; an explicitly named preset and every existing session remain unchanged.

Subject: [PATCH 163/164] feat(web): add hours to turn duration labels
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Turns running at or past 3600s now read 1小时05分03秒 / 1h 05m 03s in the
running clock, the settled Ran-for footer, and the turn-time dialog, which
share formatRunDuration. Below an hour the second and minute branches are
unchanged, and the hour rolls at the unit boundary so 60分00秒 never appears.

+# Agent Note: Turn duration labels gain an hour unit
+
+Status: implemented
+
+English | [中文](2026-09-09-turn-duration-hour-unit.zh.md)
+
+## Problem
+
+The Web chat's turn duration labels counted minutes without bound. `formatRunDuration` in [message-chrome.ts](../../../../packages/client/ui-chat/src/client/chat/message-chrome.ts) split elapsed milliseconds into seconds and minutes only, so a turn that ran for 90 minutes read `90分05秒` / `90m 05s` in all three places sharing the formatter: the `Deep diving...` running clock, the settled `Ran for {duration}` footer, and the turn-time dialog's total. The archived [turn run time decision](../../archived/feature/2026-08-03-web-turn-run-time.md) fixed the clock's anchor and the shared whole-second floor; it left the formatter at two units, which stops reading correctly once a turn crosses an hour.
+
+## Decision
+
+`formatRunDuration` carries an hour branch: elapsed time at or above 3600 seconds renders through `duration.hours` with zero-padded minutes and seconds — `1小时05分03秒` / `1h 05m 03s` — while everything below an hour keeps the existing second and minute branches unchanged. Hours appear only at or above 3600 seconds, so 3599 seconds still reads `59分59秒` and `60分00秒` never appears. Seconds are retained rather than dropped once hours appear, because the running clock ticks every second and a `1小时05分` label would sit still for a minute at a time. Negatives still clamp to zero and partial seconds still floor. `duration.hours` joins both dictionaries in [locale.ts](../../../../packages/client/ui-chat/src/client/locale.ts), and `RunDurationTranslate` widens to three keys.
+
+The change is confined to the turn formatter. `StatsPills.formatDuration` — the session-wide aggregate pill reading `45.2s` / `2m42s` — keeps its own two-unit format.
+
+## Alternatives considered
+
+**Pair hours with minutes only.** Dropping seconds at the hour boundary matches the `ui-jobs` job-duration format and keeps the label short. It loses the second-level figure from the settled footer, and it makes the live clock look frozen: the label would change once a minute while the turn is still running.
+
+**Three units while running, two once settled.** Rejected because both readings come from one function by design — the archived decision pins that — so the same turn would report different precision before and after it settles.
+
+**Change the aggregate pill in the same change.** `StatsPills.formatDuration` measures session-wide aggregates — LLM time, tool time, and average TTFT — from projections rather than one turn's boundaries. It can exceed an hour too, but folding it in would mix two independent formatters and their tests into one change.
+
+**Leave minutes unbounded.** `90分05秒` is technically correct and costs nothing to keep, but it is the reading that prompted this change and grows harder to parse the longer a turn runs.
+
+## Consequences
+
+Long turns now read in hours without new session events or new timing state; the labels remain derived from the logged `turn/start` and `turn/end` boundaries and keep the 15-second clock delay. The unit spec covers the 3599-second and 3600-second boundary plus the English template. No recorded-session snapshot changes: every shipped `Deep diving...` expectation is captured before the clock appears.

+# Agent Note: 回合耗时标签增加小时单位
+
+Status: implemented
+
+[English](2026-09-09-turn-duration-hour-unit.md) | 中文
+
+## 问题
+
+Web 聊天的回合耗时标签分钟数无界增长。[message-chrome.ts](../../../../packages/client/ui-chat/src/client/chat/message-chrome.ts) 里的 `formatRunDuration` 只把毫秒拆成秒和分两级，于是一个跑了 90 分钟的回合在共用一个格式化器的三处都读作 `90分05秒` / `90m 05s`：`Deep diving...` 后的实时计时、收尾的 `Ran for {duration}` 页脚，以及耗时详情弹窗里的总用时。已归档的[回合运行时长决策](../../archived/feature/2026-08-03-web-turn-run-time.md)确定了计时锚点和共用的整秒向下取整；它把格式化器留在两级单位，一旦回合跨过一小时就不再正确。
+
+## 决定
+
+`formatRunDuration` 增加小时分支：总时长达到或超过 3600 秒时经 `duration.hours` 渲染，分和秒补零——`1小时05分03秒` / `1h 05m 03s`——不足一小时的时长保持原有的秒、分两级不变。小时只在达到或超过 3600 秒时出现，因此 3599 秒仍读作 `59分59秒`，不会出现 `60分00秒`。出现小时后保留秒而不丢弃，因为实时计时每秒都在走，`1小时05分` 这样的标签会整整一分钟静止不动。负值仍然钳到 0，不足一秒仍然向下取整。[locale.ts](../../../../packages/client/ui-chat/src/client/locale.ts) 的两套字典都新增 `duration.hours`，`RunDurationTranslate` 扩为三个键。
+
+改动只限于回合计时器。`StatsPills.formatDuration`——会话级聚合胶囊，读作 `45.2s` / `2m42s`——保留自己的两级格式。
+
+## 考虑过的替代方案
+
+**小时只与分配对。** 在小时边界丢掉秒与 `ui-jobs` 的任务时长格式一致，标签也更短。代价是收尾页脚失去秒级数字，并且实时计时看起来像卡住了：回合还在跑，标签却每分钟才变一次。
+
+**运行中三单位、收尾两单位。** 拒绝，因为两处读数按设计来自同一个函数——归档决策锁定了这一点——同一个回合会在结束前后报告不同的精度。
+
+**在同一次改动里改聚合胶囊。** `StatsPills.formatDuration` 统计的是来自投影的会话级聚合值——LLM 耗时、工具耗时与平均 TTFT——而不是单个回合的边界。它同样可能超过一小时，但把它折进来会让两个独立的格式化器及其测试混进同一次改动。
+
+**保留分钟无界。** `90分05秒` 在技术上没错，保留也不花成本，但它正是引发这次改动的读数，而且回合跑得越久越难解析。
+
+## 后果
+
+长回合现在按小时展示，没有新增会话事件或计时状态；标签仍由日志中的 `turn/start` 与 `turn/end` 边界派生，并保留 15 秒后才出现计时的延迟。单元 spec 覆盖 3599 秒与 3600 秒的边界以及英文模板。录制会话快照没有变化：所有已发布的 `Deep diving...` 期望都在计时出现之前就被捕获。

+# Agent Note: Identify approval review workflows by file path
+
+Status: implemented
+
+English | [中文](2026-09-10-approval-review-workflow-identity.zh.md)
+
+## Problem
+
+GitHub can populate a workflow run's `name` with its expanded `run-name`. The approval review workflow includes the pull-request number in that title, so comparing `workflow_run.name` with the static workflow name rejects valid review events before refreshing the approval status.
+
+## Decision
+
+The [approval publisher](../../../../.github/review-ownership/check-approval.mjs) identifies the review-event workflow by its exact `workflow_run.path`. It also requires a successful `pull_request_review` run, parses the pull-request number from `display_title`, validates any supplied pull-request association, and compares the current pull-request head with the reviewed head before evaluating approvals.
+
+## Alternatives considered
+
+**Accept a name prefix.** A display name does not identify the workflow file; another workflow can use the same title.
+
+**Remove the numbered run title.** The title supplies the pull-request number when GitHub returns an empty `pull_requests` array. Removing it requires a different handoff mechanism.
+
+## Consequences
+
+Run-title expansion does not prevent approval refreshes, while an unexpected workflow file still fails validation. Moving the review-event workflow requires updating the publisher's expected path.
+
+[Approval policy tests](../../../../.github/review-ownership/check-approval.test.mjs) cover a numbered run name, invalid source paths and events, unsuccessful runs, invalid titles, and superseded heads. The [approval outcome policy](2026-09-09-blocked-weighted-approvals-remain-pending.md) continues to own pending and successful status semantics.

+# Agent Note: 按文件路径识别审批评审工作流
+
+Status: implemented
+
+[English](2026-09-10-approval-review-workflow-identity.md) | 中文
+
+## 问题
+
+GitHub 可能用展开后的 `run-name` 填充工作流运行的 `name`。审批评审工作流在该标题中包含拉取请求编号，因此将 `workflow_run.name` 与静态工作流名称比较，会在刷新审批状态前拒绝有效的评审事件。
+
+## 决策
+
+[审批发布器](../../../../.github/review-ownership/check-approval.mjs) 按精确的 `workflow_run.path` 识别评审事件工作流。它还要求该运行由 `pull_request_review` 触发且成功完成，从 `display_title` 解析拉取请求编号，验证提供的拉取请求关联，并在计算审批结果前将拉取请求当前的头提交与已评审的头提交进行比较。
+
+## 考虑过的替代方案
+
+**接受名称前缀。** 显示名称无法识别工作流文件；另一个工作流可以使用相同的标题。
+
+**删除带编号的运行标题。** 当 GitHub 返回空的 `pull_requests` 数组时，标题提供拉取请求编号。删除它需要另一种传递机制。
+
+## 影响
+
+运行标题的展开不会阻止审批刷新，而非预期的工作流文件仍无法通过验证。移动评审事件工作流时，需要更新发布器预期的路径。
+
+[审批策略测试](../../../../.github/review-ownership/check-approval.test.mjs) 覆盖带编号的运行名称、无效的来源路径和事件、未成功的运行、无效标题以及已被替代的头提交。[审批结果策略](2026-09-09-blocked-weighted-approvals-remain-pending.zh.md) 继续负责待定与成功状态的语义。

 ## Security
 
-The status-writing job checks out only the repository default branch. It does not check out or execute pull-request code and does not use repository secrets. The review-event workflow has no `GITHUB_TOKEN` permissions and passes only a decimal pull-request number in its run title. The publisher rejects an invalid run title and a number that does not resolve to the workflow run's current pull-request head. Pull-request reviews are treated as API data and escaped in logs.

 Approval policy changes take effect only after they merge into the default branch. This prevents an untrusted pull request from changing the program or policy for its own run.
