From cdb4cc3c6889ab090713140f663a96e0f7d0fe1d Mon Sep 17 00:00:00 2001 From: _Kerman Date: Wed, 19 Aug 2026 21:02:30 +0800 Subject: [PATCH 01/50] feat(session-projection-cache): store one projection_cache.json per session MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the single global session_projcache domain with a per-session cache file inside the session's own persistence directory, resolved through sessionPersistence.locate(meta) — the persistence backend owns the session-directory layout, the cache service keeps every checkpoint and cold-read responsibility. - cachedSnapshot(meta) becomes async (one file read per session); coldSnapshot takes the session header so it can locate the file, with the stored log header remaining the identity witness. - Backends without a per-session directory (sqlite) disable the durable cache: writes no-op and cold reads fall to the full-log rung. An obsolete global cache is never read — derived data refolds on first cold read (no migration). - writeAtomic is exported from dsh-storage-json as the shared atomic whole-file replace primitive; api-proxy listing and subagent cold reads await the now-async cachedSnapshot. - READMEs and a new Agent Note document the per-session medium. --- ...ojection-cache-per-session-files.i18n.yaml | 6 + ...8-19-projection-cache-per-session-files.md | 28 ++ ...9-projection-cache-per-session-files.zh.md | 28 ++ apps/web/tests/agent-preset-selection.e2e.ts | 9 +- apps/web/tests/subagent-conversation.e2e.ts | 16 +- docs/subsystems/session-projection.i18n.yaml | 4 +- docs/subsystems/session-projection.md | 32 +- docs/subsystems/session-projection.zh.md | 32 +- .../extensions/tool-cordis/src/api-catalog.ts | 12 +- packages/host/apiproxy/src/api-proxy.ts | 16 +- .../apiproxy/tests/api-proxy-cold.spec.ts | 2 +- .../tests/api-proxy-projections.spec.ts | 2 +- .../session-projection-cache/README.i18n.yaml | 4 +- .../session-projection-cache/README.md | 15 +- .../session-projection-cache/README.zh.md | 7 +- .../session-projection-cache/package.json | 5 +- .../session-projection-cache/src/index.ts | 171 ++++++----- .../session-projection-cache/src/invariant.ts | 4 +- .../session-projection-cache/src/spec.ts | 31 +- .../tests/cache.spec.ts | 284 ++++++++++-------- .../session-projection-cache/tsconfig.json | 5 +- packages/storage/storage-json/src/index.ts | 1 + .../subagent/subagent/src/list-children.ts | 2 +- .../subagent/tests/list-children.spec.ts | 14 +- pnpm-lock.yaml | 6 +- 25 files changed, 431 insertions(+), 305 deletions(-) create mode 100644 .agents/notes/implemented/architecture/2026-08-19-projection-cache-per-session-files.i18n.yaml create mode 100644 .agents/notes/implemented/architecture/2026-08-19-projection-cache-per-session-files.md create mode 100644 .agents/notes/implemented/architecture/2026-08-19-projection-cache-per-session-files.zh.md diff --git a/.agents/notes/implemented/architecture/2026-08-19-projection-cache-per-session-files.i18n.yaml b/.agents/notes/implemented/architecture/2026-08-19-projection-cache-per-session-files.i18n.yaml new file mode 100644 index 0000000000..b53cdb34eb --- /dev/null +++ b/.agents/notes/implemented/architecture/2026-08-19-projection-cache-per-session-files.i18n.yaml @@ -0,0 +1,6 @@ +# Bilingual-pair consistency record (docs/i18n/README.md): the git blob hash of each +# side as of the last confirmed-consistent state.

The per-record unit is stateless — the directory is the state, loadAll re-reads the tree, and every write is a single durable file operation — while single keeps its authoritative in-memory state and whole-file publish. Records keys must be path-safe ([a-zA-Z0-9_-]+); an unsafe key rejects. A record document that is malformed or stamped with another version reads as an absent record: one bad or stale file never bricks the unit, and a version bump discards stale records instead of migrating them. DomainSpec and KvUnitDescriptor gain the optional layout field (defineDomain validates it, descriptorOf projects it). --- packages/storage/storage-domain/src/spec.ts | 17 ++ packages/storage/storage-json/src/format.ts | 41 +++- packages/storage/storage-json/src/index.ts | 21 +- .../storage-json/src/per-record-unit.ts | 206 ++++++++++++++++++ .../src/{unit.ts => single-unit.ts} | 23 +- packages/storage/storage/src/backend.ts | 13 +- 6 files changed, 302 insertions(+), 19 deletions(-) create mode 100644 packages/storage/storage-json/src/per-record-unit.ts rename packages/storage/storage-json/src/{unit.ts => single-unit.ts} (85%) diff --git a/packages/storage/storage-domain/src/spec.ts b/packages/storage/storage-domain/src/spec.ts index bf5de09a29..74348918aa 100644 --- a/packages/storage/storage-domain/src/spec.ts +++ b/packages/storage/storage-domain/src/spec.ts @@ -37,6 +37,14 @@ export interface DomainSpec { readonly name: string /** Domain format version; a medium stamped with a different version rejects at open. */ readonly version: number + /** + * Medium layout for the backend unit: `single` (the default) stores the + * whole unit as one document; `per-record` stores each record as its own + * document, for units whose records are large, sparse, or individually + * disposable — the projection cache — and scopes version bumps per record + * (a stale record document is discarded, never migrated). + */ + readonly layout?: 'single' | 'per-record' /** Optional global singleton slot. */ readonly global?: DomainGlobalSpec /** Table declarations keyed by table name; each name must match `UNIT_NAME_RE`. */ @@ -83,6 +91,14 @@ export function defineDomain(spec: S): S { if (!Number.isInteger(spec.version) || spec.version < 0) { throw new Error(`domain '${spec.name}' version must be a non-negative integer, got ${spec.version}`) } + if (spec.layout !== undefined) { + // Runtime boundary: the union type is compile-time only — a spec built + // from config could carry any value, and a bad one must fail loud here. + const layout: string = spec.layout + if (layout !== 'single' && layout !== 'per-record') { + throw new Error(`domain '${spec.name}' layout must be 'single' or 'per-record', got ${layout}`) + } + } for (const table of Object.keys(spec.tables)) { if (!UNIT_NAME_RE.test(table)) { throw new Error(`domain '${spec.name}' table name '${table}' must match ${UNIT_NAME_RE}`) @@ -108,5 +124,6 @@ export function descriptorOf(spec: DomainSpec): KvUnitDescriptor { version: spec.version, tables: Object.keys(spec.tables), hasGlobal: spec.global !== undefined, + ...spec.layout === undefined ? {} : { layout: spec.layout }, } } diff --git a/packages/storage/storage-json/src/format.ts b/packages/storage/storage-json/src/format.ts index 55efb830b7..045485eaba 100644 --- a/packages/storage/storage-json/src/format.ts +++ b/packages/storage/storage-json/src/format.ts @@ -1,7 +1,11 @@ /** * On-disk JSON unit format: the file is always the current net state, kept * human-readable (pretty-printed, stable key order from insertion) — that - * legibility is this backend's reason to exist. + * legibility is this backend's reason to exist. `single`-layout units are + * one document with a unit header; `per-record`-layout units are a directory + * with one version-stamped document per record (`

Reads and writes now share ONE coherent state: cachedSnapshot reads synchronously from the domain's in-memory tables, and every write is durability-first-then-memory, so a read can never go around the write chain to the medium. The hand-rolled write chains, in-flight tracking, per-session file paths, owner-only file modes, and the sqlite no-path special case are gone; Config.root is removed and the domain's version stamp makes a checkpointRecord bump discard stale sessions per record instead of rejecting the whole medium. The async ripple of the old file read is reverted: api-proxy's listing column and subagent's cold identity read go back to synchronous cachedSnapshot. --- packages/host/apiproxy/src/api-proxy.ts | 14 +- .../session-projection-cache/package.json | 10 +- .../session-projection-cache/src/index.ts | 178 +++++++----------- .../session-projection-cache/src/spec.ts | 29 ++- .../session-projection-cache/tsconfig.json | 5 +- .../subagent/subagent/src/list-children.ts | 2 +- 6 files changed, 110 insertions(+), 128 deletions(-) diff --git a/packages/host/apiproxy/src/api-proxy.ts b/packages/host/apiproxy/src/api-proxy.ts index 129c845dfa..597e757514 100644 --- a/packages/host/apiproxy/src/api-proxy.ts +++ b/packages/host/apiproxy/src/api-proxy.ts @@ -800,15 +800,15 @@ function projectionsFor(ctx: Context, session: Session): SessionProjectionsBlock * empty value set — yields an absent block: a listing without projections * is degraded, never broken. */ -async function listProjectionsFor( +function listProjectionsFor( ctx: Context, meta: SessionHeader, session: Session | undefined, -): Promise { +): SessionProjectionsBlock | undefined { try { const block = session !== undefined ? ctx.get('sessionProjections')?.snapshot(session) - : await ctx.get('sessionProjectionCache')?.cachedSnapshot(meta) + : ctx.get('sessionProjectionCache')?.cachedSnapshot(meta) return block !== undefined && Object.keys(block.values).length > 0 ? block : undefined } catch (error) { ctx.logger.warn(`session.list: projection column for "${meta.id}" failed (serving the row without it): ${String(error)}`) @@ -1674,15 +1674,15 @@ export function createApiProxy(ctx: Context, defaults: ApiProxyDefaults): ApiPro */ async function listVisibleSessionSummaries(signal?: AbortSignal): Promise { signal?.throwIfAborted() - const summarizeAttached = async (session: Session): Promise => { + const summarizeAttached = (session: Session): SessionSummary => { const agent = ctx.agents.get(session.id) - const projections = await listProjectionsFor(ctx, session.header, session) + const projections = listProjectionsFor(ctx, session.header, session) return { ...summarize(session, agent?.status === 'running'), ...projections === undefined ? {} : { projections }, } } - const items = await Promise.all(ctx.sessions.list().map(summarizeAttached)) + const items = ctx.sessions.list().map(summarizeAttached) signal?.throwIfAborted() const attached = new Set(items.map(item => item.sessionId)) const persistence = ctx.get('sessionPersistence') @@ -1697,7 +1697,7 @@ export function createApiProxy(ctx: Context, defaults: ApiProxyDefaults): ApiPro batch.map(async (meta) => { // Projection hints remain optional.

text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Cache README (EN/ZH): the medium is the session_projcache domain in per-record layout (one version-stamped document per session under the json backend root), reads are synchronous from the domain's in-memory tables, and the storage stack rides in base. storage-json README documents both layouts and their contracts; web-app README notes that storage and the projection cache live in the shared base. Regenerated: session-projection subsystem catalog (sync cachedSnapshot, domain medium), config-catalog (Config.root gone), module-graph (cache now depends on storage-domain, not session-persistence), cli composition (storage rows in base), and the projection-cache Agent Note — which now records the file-root revision and its revert as rejected alternatives. --- ...ojection-cache-per-session-files.i18n.yaml | 4 ++-- ...8-19-projection-cache-per-session-files.md | 17 ++++++------- ...9-projection-cache-per-session-files.zh.md | 17 ++++++------- apps/cli/composition.md | 15 +++++++++--- docs/config-catalog.i18n.yaml | 4 ++-- docs/config-catalog.md | 10 ++++---- docs/config-catalog.zh.md | 10 ++++---- docs/module-graph.i18n.yaml | 4 ++-- docs/module-graph.md | 3 +-- docs/module-graph.zh.md | 3 +-- docs/subsystems/session-projection.i18n.yaml | 4 ++-- docs/subsystems/session-projection.md | 24 ++++++++++--------- docs/subsystems/session-projection.zh.md | 24 ++++++++++--------- packages/bundle/web-app/README.i18n.yaml | 2 +- packages/bundle/web-app/README.md | 2 +- .../extensions/tool-cordis/src/api-catalog.ts | 12 +++++----- .../session-projection-cache/README.i18n.yaml | 4 ++-- .../session-projection-cache/README.md | 22 +++++++++-------- .../session-projection-cache/README.zh.md | 22 +++++++++-------- .../storage/storage-json/README.i18n.yaml | 4 ++-- packages/storage/storage-json/README.md | 11 ++++++--- packages/storage/storage-json/README.zh.md | 11 ++++++--- 22 files changed, 126 insertions(+), 103 deletions(-) diff --git a/.agents/notes/implemented/architecture/2026-08-19-projection-cache-per-session-files.i18n.yaml b/.agents/notes/implemented/architecture/2026-08-19-projection-cache-per-session-files.i18n.yaml index 7b6ad0fc3e..57f96906a8 100644 --- a/.agents/notes/implemented/architecture/2026-08-19-projection-cache-per-session-files.i18n.yaml +++ b/.agents/notes/implemented/architecture/2026-08-19-projection-cache-per-session-files.i18n.yaml @@ -2,5 +2,5 @@ # side as of the last confirmed-consistent state.

Deliberate asymmetries with Python: the launch spec is explicit `command`/`args` (no bundled-runtime resolution — that is a distribution concern with no TS consumer yet); `env` replaces rather than merges (callers own credential policy; `scrubbedParentEnv` from the subprocess seam is one import away); `TurnResult` carries the structured `reason` (Python exposes only `status`); teardown walks a private stdin-EOF → SIGTERM → SIGKILL ladder to actual exit (the client runs outside any harness context, so it cannot ride `ctx.subprocess`). -- **`@deepseek-ai/dsh-subagent-dsh-sdk`** (`packages/subagent/subagent-dsh-sdk/`) — the second out-of-process `SubagentProvider`, structured as `subagent-acp`'s sibling: same all-false capabilities and `inheritsParentContext: false`, same publish-after-handshake ownership transaction, same result-never-rejects flattening through an `onError` sink, same parent-namespace run id.

The provider reads the last durable `turn/end` inside that activity and maps it into the seam vocabulary: `completed` → `completed`, `max-tokens` → `max-tokens`, `aborted` → `aborted`; everything else — `error`, `interrupted`, `disposed`, a future variant, or an activity with no turn — maps to `error`, so an unclean stop is never reported as success.

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

Reachable child failures and SDK errors add the bounded safe diagnostic defined by the [out-of-process diagnostics decision](2026-08-21-out-of-process-subagent-minimal-diagnostics.md), using one category plus the current provider stage.

Process mechanics (spawn, env scrub, tree-scoped teardown) live in the `dsh-subprocess` seam; `subagent-acp` spawns through `ctx.subprocess`, while this backend spawns through the SDK client (the subprocess README's documented exception for SDK-managed transports) and applies the seam's `scrubbedParentEnv()` itself. `dsh-sdk-jsonrpc-server` keeps serving unchanged (the wire is byte-identical); `dsh-jsonrpc-agent-pkg` (the Python runtime closure) gains the `dsh-sdk-protocol` dependency line. @@ -23,7 +23,7 @@ Three packages, layered exactly like the existing Python stack, plus one Service Four tiers, per [testing policy](../../../../docs/testing.md): -- **Keyless unit** — `sdk-client` drives a scripted fake runtime (`tests/fake-runtime.ts`, env-scripted, protocol-only — the Python `test_client.py` pattern) over real stdio; `subagent-dsh-sdk` drives the same fake through the real provider, including child-reason, typed-error, startup, process, and shutdown diagnostics. 100% per-file coverage on all three packages. +- **Keyless unit** — `sdk-client` drives a scripted fake runtime (`tests/fake-runtime.ts`, env-scripted, protocol-only — the Python `test_client.py` pattern) over real stdio; `subagent-dsh-sdk` drives the same fake through the real provider, including reachable child reasons, typed errors, and initialize/session-run/shutdown diagnostics. 100% per-file coverage on all three packages. - **Keyless Loader composition** — `subagent-dsh-sdk/tests/loader-composition.e2e.ts` boots a test-only cordis.yml (`examples/jsonrpc-agent/tests/fixtures/subagent/subagent-dsh-sdk/`) where the child is a REAL second harness runtime with its own cordis.yml; asserts cwd inheritance and the model-visible child-error diagnostic with separate partial output.

When a background run settles, the runtime sends you a notice containing its outcome and any final assistant message. diff --git a/snapshots/session/workflow-run/session.jsonl b/snapshots/session/workflow-run/session.jsonl index 3c35405c52..97533bfe91 100644 --- a/snapshots/session/workflow-run/session.jsonl +++ b/snapshots/session/workflow-run/session.jsonl @@ -29,7 +29,8 @@ {"type":"step/end","data":{"turn":1,"step":1}} {"type":"step/start","data":{"turn":1,"step":2}} {"type":"assistant/chunk","data":{"turn":1,"step":2,"chunk":{"type":"block-start","index":0,"blockType":"reasoning"}}} -{"type":"reasoning-chunks","data":{"turn":1,"step":2,"index":0,"dt":[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0],"texts":["The"," workflow"," returned"," successfully"," with"," the"," reply"," \"","WF","_CH","ILD","_OK","\"."," Now"," I"," need"," to"," reply"," with"," exactly"," \"","WORK","FL","OW","_D","ONE","\""," and"," stop","."]}} +{"type":"reasoning-chunks","data":{"turn":1,"step":2,"index":0,"dt":[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],"texts":["The"," workflow"," returned"," successfully"," with"," the"," reply"," \"","WF","_CH","ILD","_OK","\"."," Now"," I"," need"," to"," reply"," with"," exactly"," \"","WORK","FL","OW","_D","ONE"]}} +{"type":"reasoning-chunks","data":{"turn":1,"step":2,"index":0,"dt":[0,1,0],"texts":["\""," and"," stop","."]}} {"type":"assistant/chunk","data":{"turn":1,"step":2,"chunk":{"type":"block-start","index":1,"blockType":"text"}}} {"type":"text-chunks","data":{"turn":1,"step":2,"index":1,"dt":[0,0,0,0],"texts":["WORK","FL","OW","_D","ONE"]}} {"type":"assistant/chunk","data":{"turn":1,"step":2,"chunk":{"type":"block-end","index":0,"block":{"type":"reasoning","text":"The workflow returned successfully with the reply \"WF_CHILD_OK\".
