 2. The `dsh-client-modules` node half (the package is dual-face: its browser half is the module table) scans loader entries' package.json `dsh.client` declarations and composes `window.__DSH_BOOT__`: `{ rev, entries: [{ id, url, rev, inject?, immediately? }] }`. The `inject` edges and the `immediately` mark come from manifests, never hand-copied. It refuses declared plugins without built `./client` bundles and groups their package/path rows under one required source-build instruction; malformed declaration fields also fail activation, and the host audit reports either error from the FAILED fiber.
 3. Scanning is incremental per package — there is no full-rescan code path. Each cordis `internal/plugin` emission marks the fiber's entry name dirty (entry-less fibers drop O(1)); a microtask flush reconciles each dirty name against live loader entries, with package metadata (including the negative "not a client package" verdict) cached per name forever and bundle re-hashing reachable only through `rebuilt(id)`. The activation pass seeds the same dirty set from current entries and flushes synchronously, so first scan and steady state share one implementation. Each bundle's content hash is its `rev` (cache busting + HMR diff anchor), the row set hashes into `graph.rev`, and every row is served as a script resource at `/plugins/<id>/client.js?rev=…`, with its source map at the same path plus `.map`. The graph types are single-sourced in the modules package's `./client` export — the webserver knows nothing about the graph (it is a plain route-registration plugin; modules registers the bundle route and taps the index render itself).

 ### Hot reload: one driver plugin, self-watched bundles
 
-Whether hot reload is active is a composition decision: dev compositions mount the `client-hmr` row (a normal plugin package, appended by `--dev`) whose node half brings the bundle watch and the SSE channel; prod compositions mount nothing and have neither.
+Hot reload is a composition decision: the web bundle mounts the `client-hmr` row (a normal plugin package) unconditionally; its node half brings the bundle watch and the SSE channel, and the chain stays idle until a rebuild watcher rewrites client bundles. A composition that must not expose it disables the row.
 
 How does a rebuilt bundle become a reload signal? The hmr node half observes it itself — no builder tells it. It reads bundle paths from `ctx.clientModuleHost.clientPath(id)`, and one HMR-owned interval stat-polls every current graph row. Adding a row is ordered as synchronous stat baseline, then immediate `clientModuleHost.rebuilt(id)`: a write after the module host's graph hash but before that baseline is caught by the immediate re-hash, while a write after the baseline leaves a stat delta for the next poll. This avoids `fs.watchFile`, whose asynchronous first baseline can silently absorb a construction-time rebuild. Watch membership follows `onGraphChanged`; vanished rows drop out, and a bundle missing at poll time keeps its row dirty so reappearance forces a re-hash even with identical metadata. On a mtime/size delta or dirty row, `clientModuleHost.rebuilt(id)` is the single re-hash entry point; when the `rev` actually changed, the node half broadcasts a `rebuilt` frame on `GET /plugins/events` — a system SSE channel that sends the full graph on connect and `rebuilt` frames on change, presentation-only wire that never enters the session log. Polling is deliberate because inotify does not fire on the weka network mount, the same reason the build-side watcher needs `--poll`; the interval is a validated config field (default 500ms), and disposal clears the one timer. Rebuilding bundles is any tsdown watch process's business — `scripts/dev-web.ts` remains the watch-build entry point, discovering its package list through `dsh.client` while scanning `packages/*/*/package.json` at startup — and builder and host share zero protocol. A torn read self-heals: stats keep changing while the write completes, so the next poll re-hashes and broadcasts the final rev.

Plugin packages have one shape, so the purity gate covers them all.

The drift classes stay structurally closed: share-list hand-sync, load-order coupling, cross-plugin imports, roster/tier double bookkeeping.

 Costs accepted: the vendored Loader carries idle machinery in the browser (EntryTree persistence is a no-op, groups/isolation unused); every plugin edit in dev pays a bundle rebuild plus fiber remount; graph `inject` rows are informational — activation truth is service-level — so a mismatch appears at the settled sweep, not at graph validation; the three not-yet-promoted libraries keep their static-import exports until their DI conversions land; every bundle gains a source-map artifact; and external-script failures provide only coarse URL diagnostics instead of the HTTP status available to an explicit fetch.

 重建好的 bundle 怎么变成重载信号？hmr 的 node 半自己观察——没有构建器来通知它。它从 `ctx.clientModuleHost.clientPath(id)` 读取图上各行的 bundle 路径，由 HMR 自持的单个定时器对当前图上的每一行做 stat 轮询。新增图行时，顺序固定为先同步取得 stat 基线，再立即调用 `clientModuleHost.rebuilt(id)`：在模块 host 算出图哈希之后、取得基线之前发生的写入会被这次立即重哈希捕获；取得基线之后发生的写入则会留下 stat 差异，供下一次轮询捕获。这避开了 `fs.watchFile`：它以异步首次 stat 建立基线，可能把构造期间的重建静默吸收进基线。监视集合的成员随 `onGraphChanged` 更新；消失的行撤下监视，轮询时缺失的 bundle 则让对应行保持标脏状态，文件重现时即使元数据相同也强制重哈希。mtime/size 变化或行处于标脏状态时，`clientModuleHost.rebuilt(id)` 是重哈希的唯一入口；当 `rev` 真的变了，node 半才在 `GET /plugins/events` 上广播 `rebuilt` 帧——这是一条系统级 SSE 通道，连接即发全量图，变更时发 `rebuilt` 帧，仅供呈现的 wire，永不进会话日志。轮询是刻意选择：inotify 在 weka 网络挂载上不触发，构建侧监视器需要 `--poll` 也是同一原因；轮询间隔是一个经校验的配置字段（默认 500ms），dispose（资源释放）会清掉那一个定时器。重建 bundle 则是任意一个 tsdown watch 进程的事——`scripts/dev-web.ts` 仍作为 watch 构建入口保留，其包清单在启动时扫描 `packages/*/*/package.json` 按 dsh.client 发现——构建器与 host 共享零协议。写一半的 bundle 被撕裂读取会自愈：写入完成期间 stat 持续变化，下一个轮询节拍会再次重哈希并广播最终的 rev。

No spine bundle: every plugin is one row and every config field is yml-editable. That stance later became repository-wide, with the rows both surfaces share factored into `apps/cli/config/base.cordis.yml` and each surface reduced to an overlay ([shared-base overlays](../simplification/2026-07-29-shared-base-config-overlays.md)). `--dev` appends the `dsh-client-hmr` row in code before the settle audit — prod and dev differ by exactly that row. Row order carries no load semantics; activation is service-availability driven. The shared audit rejects imports with no fiber, awaits only failed fibers to recover original activation errors, and reports services that leave a fiber `PENDING`; before throwing, it marks those exact rejection reasons through one process checkpoint so `installFailLoud` coalesces Loader's duplicate notification while unrelated unhandled rejections remain fatal. The Node app-boot artifact embeds `@cordisjs/plugin-include` while leaving `@cordisjs/plugin-loader` external, so the include's `EntryTree` and the host bind to one Loader peer instead of splitting a config tree across two Loader implementations.

 - **`link:` entries for in-box bundles**: pnpm cannot version, install, or update a `link:` into the installation, it embeds a machine path in a user file, and it breaks when the installation moves.

 Two further consequences. Loader mounts sibling rows concurrently, so one row can activate while another still mounts or while the whole boot is rolling back; the Web bundle therefore publishes its URL only after its own Loader tree settles. The Web bundle's runtime plugin owns the harness-source prompt section too, so `dsh web` and `dsh --profile web` boot identically without Web-specific launcher setup.

+Three framework facts shape the mechanism:
 
-- **A profile's rows arrive inside the root include's `patches` option.** Include is an entry-tree owner, so its static entry-config resolver interpolates Include's own options while preserving nested `!!js` nodes for their target rows instead of recursively evaluating them in the Include context.
+- **A profile's rows arrive inside the root include's `patches` option.** Include declares the `EntryGroup.key` tree-carrier marker (as Group does), so Loader keeps its config — entry and patch lists, including Include's own `path` — literal instead of recursively evaluating nested `!!js` nodes in the Include context; each expression resolves in its target row's fiber.
 - **Cordis activates a fiber only after all declared injections are active.** Immediately before each activation, Cordis runs the `internal/config` waterfall against the fiber's own context; Loader's listener interpolates the raw config after Cordis snapshots its injected services.
 - **Provider replacement and HMR must preserve the same contract.** Fiber reactivation re-runs the waterfall, HMR carries the raw config to the replacement fiber, and a pending row accepts option changes without prematurely evaluating expressions against absent services.
-- **A row cannot be inserted from inside a mounting plugin** — `tree.create` returns a prefixed id it then fails to resolve — so a conditional row ships `disabled: true` and an active row enables it (`dsh web --dev` and its reload chain). Enablement is an in-memory Loader override rather than an options rewrite, so Include reapplication cannot silently disable it. The Web bundle also starts client discovery only after enabling the optional row, ensuring the first browser graph already contains its HMR receiver.
 
 This leaves dependency ordering in Cordis activation and Loader interpolation, which own it. Rows keep their `inject` and config, Loader mounts the composition once, and the launcher only provides argv and process-lifecycle services.

 - An app's flags, help text, and usage errors live with the rows they configure; adding a flag to an installed plugin needs no launcher change.
-- The launcher still recognizes the headless runner for one-shot process lifetime and the telemetry row for its environment switch; neither path interprets app arguments.
+- The launcher recognizes no app row at all: the telemetry row remains its only composition probe (for the environment switch), SIGTERM exits 0 on every surface, every boot watches its user patch layers, and the one-shot runner exits through `ctx.appExit` like any other app.
 - `--help` leaves every row that depends on the provider's service pending and requests bounded exit; unrelated rows may activate concurrently before teardown.
 - An app-owned service has no statically declared provider: a bundle shipping consumer rows without that provider fails at settlement with pending entries naming the service, not at load.
 - A user patch that replaces a row's whole `config` drops its expressions, and with them the flag's precedence for that row.

+# Agent Note: Remote event delivery (ctx.remote.$on)
+
+Status: implemented

+
+## Problem
+
+[TypeRT Gateway targeted method calls](../../implemented/architecture/2026-08-02-typert-remote-method-calls.md) cover only the request/response shape and deliberately leave Session event streams and stateful interactions to separate designs. Every **one-way Host-to-consumer push** therefore still rides the legacy API Proxy.
+
+The Host owns a family of one-way events whose payloads are already JSON and whose emission never binds an AgentScope: `agent-preset/selected`, `commands/change`, `credentials/updated`, `llm/adapters-updated`, and `settings/document-updated`. Reaching one UI subscriber took four hops: the Host cordis event, a hand-written `HostFrame` variant plus its zod branch in apiproxy, a hand-written bridge in client/runtime that re-emitted it as a Client cordis event, and finally the consumer's `ctx.on(...)`. Adding one such event edited five places (frame union, zod union, host-stream listener, client bridge, a duplicated Client-side `Events` declaration), and not one of them stated a new fact: the name, the payload type, and the emission point were all declared by the owner package's cordis `Events` merge.
+
+That duplicated declaration is also **lossy**: the Client side restates it as `settings/changed(ns: string)`, flattening a branded type into bare `string` — the opposite of the Remote method contract, where a consumer type points at the business package's one canonical symbol.
+
+## Decision
+
+The consumer Remote surface carries one one-way subscription verb, `ctx.remote.$on(event, listener)`, driven by an allowlist and forwarding verbatim:
+
+- `packages/api/remotes/src/remote-events.ts` holds the allowlist of forwardable Host events, and it is the single control point over what a consumer may subscribe to. `src/types.ts` beside it derives the type projection and fills the selection seat, staying type-only per the package convention. Both files are listed in the `files` of **both** of this package's faces, so the Host forwarding loop and the consumer key surface read one declaration.
+- The wire event name **is** the Host cordis event name (`settings/document-updated`) with no `host/` prefix, and the payload **is** the Host argument list, element for element, with no projection, redaction, or renaming.
+- The carrier reuses the existing host stream: `HostFrame` gains one wrapper variant, `host/remote-event`. No new downlink.
+- Event **signatures** get no second table. Each owner package moves its cordis `Events` declaration into its client-safe, type-only `./types` export, so both faces read the same declaration and `$on`'s listener type is `Events[Event]` itself. "Verbatim" then holds by construction rather than by proof.
+- Only cordis's *type shape* is borrowed, not its event system: delivery semantics, the subscription registry, and failure containment belong to TypeRT.
+
+When an `Events` entry's signature reaches a Host-only symbol (a Service, `Agent`, a Context), the answer is to **split the code until the entry lands cleanly in `./types`** — never a declaration half-left in `index.ts`, and never a structurally equivalent shadow type in `./types`. None of the five packages needs that here: their entries reach only `SettingsNamespace`, `SettingsUpdateSource`, `CredentialRef`, and `SessionId`, all pure types. The agent-presets package renames its previous vocabulary module to `preset.ts`, leaving the exported `types.ts` dedicated to the client-safe event declaration.
+
+All five events ride this path, and their dedicated `HostFrame` variants or Client aliases are gone. Model consumers subscribe directly to both owner inputs, `llm/adapters-updated` and `settings/document-updated`; preset-derived consumers subscribe to `agent-preset/selected`. Frames that actually project or deduplicate data stay dedicated: `host/workspace-changed`/`-removed`/`host/archived-sessions-changed` (view derivation plus per-connection dedup state), and `host/session-added`/`-removed`/`host/session-status`/`host/agent-error` (live-object projection or frame-time derived fields).
+
+`skills/change`, `tools/change`, and `system-prompt/change` have the same shape but **no consumer today**; under "require a current owner and need" they stay out of the allowlist and are recorded here only as the extension seat.
+
+### Consumer contract (dsh-type-meta)
+
+type-meta gains one **shape predicate**, one **selection seat**, and **one** member on `TypeRTClientRemote`. No runtime code:
+
+```ts
+import type { Events } from '@deepseek-ai/cordis'
+
+/** Cordis events shaped for one-way remote delivery: no Scope binding, void return. */
+export type TypeRTForwardableEvent = {
+  [Event in keyof Events]: unknown extends ThisParameterType<Events[Event]>
+    ? ReturnType<Events[Event]> extends void ? Event : never
+    : never
+}[keyof Events]
+
+/** The Host assembly's forwarding selection; api/remotes' allowlist fills it, no other package does. */
+export interface TypeRTRemoteEventSelection {}
+
+/** `$on`'s legal keys: selected, and present in the current compilation face. */
+export type TypeRTRemoteEvent = Extract<keyof Events, keyof TypeRTRemoteEventSelection>
+```
+
+```ts ignore-check
+/** Subscribe to one forwarded Host event; the returned disposer belongs to the calling fiber. */
+$on<Event extends TypeRTRemoteEvent>(event: Event, listener: Events[Event]): () => void
+```
+
+`Events` resolves per program: the full Host vocabulary in the Host program, whatever the Client face can see in the Client program. The same predicate therefore holds on both sides without dragging Host declarations into the Client.
+
+**The surface separates the consumer verb from the carrier handoff**: consumers subscribe with `$on`, and whoever owns the Host frame sink hands each decoded frame over with `$dispatch`. It cannot be a module-level function reaching across Client plugins — the client bundle purity gate (`packages/client/tsdown.client.ts`) admits value imports only from `CLIENT_EXTERNALS`, the `INLINE_SAFE` wire layer, and generated `/remote` contributions, and inlining around it would copy `ClientRemoteService` into the runtime bundle, making `instanceof` permanently false. A cordis service method is the collaboration shape that gate prescribes:
+
+```ts ignore-check
+$dispatch(event: string, args: readonly unknown[]): void
+```
+
+client/runtime — the owner of the host frame sink — calls it directly, so the frame reaches the subscription table without an intermediate event to relay it. The `event` parameter is `string`, not `TypeRTRemoteEvent`: this is a wire boundary, and a name nobody subscribed to is dropped silently.
+
+Delivery shares no implementation with the cordis event system: one-way only, no waterfall/bail/parallel/serial modes and no `@mode` concept (`ReturnType extends void` is the static expression of that rule), no `this` binding, no `EventOptions`, `prepend`, or priority. Listeners run in registration order, and one that throws is contained and logged — it must never take down the frame pump (the same posture `ConnectionController` already applies to its sinks).
+
+### The allowlist: one declaration both faces read
+
+`packages/api/remotes/src/remote-events.ts` is listed in the `files` of both `tsconfig.host.json` and `tsconfig.client.json`, and is the allowlist's single home; `src/types.ts` derives its type face:
+
+```ts
+// remote-events.ts — the value
+export const API_REMOTE_FORWARDED_EVENTS = [
+  'agent-preset/selected',
+  'commands/change',
+  'credentials/updated',
+  'llm/adapters-updated',
+  'settings/document-updated',
+] as const
+
+// types.ts — the type face, derived
+export type ApiRemoteForwardedEvent = typeof API_REMOTE_FORWARDED_EVENTS[number]
+
+declare module '@deepseek-ai/dsh-type-meta' {
+  interface TypeRTRemoteEventSelection extends Record<ApiRemoteForwardedEvent, true> {}
+}
+```
+
+Forwarding one more event is therefore **one line in that array**: the type projection, `$on`'s key surface, and the Host forwarding loop all derive from it. `ctx.remote.$on('slots/changed', …)` (a Client-local event) and `$on('skills/change', …)` (declared but unselected) are both **compile errors**.
+
+The Host face adds one shape assertion, binding the Host event vocabulary to that same array:
+
+```ts ignore-check
+API_REMOTE_FORWARDED_EVENTS satisfies readonly TypeRTForwardableEvent[]
+```
+
+It is an expression statement rather than a named constant, which `noUnusedLocals` would reject (the underscore prefix exempts parameters only). It enforces three things: the **name is real** (the predicate is keyed on `keyof Events`), the event **binds no Scope** (`goal/changed` and kin have a `ThisParameterType` other than `unknown` and drop out — the static expression of "no AgentScope dependency"), and the event is **one-way** (a non-`void` return, i.e. a waterfall/bail shape, drops out).
+
+**"Verbatim" is proved nowhere because it holds by construction**: `$on`'s listener type comes from the one cordis `Events` declaration in the owner package's `./types`, and Host forwarding reads that same declaration. There is no second declaration that could drift.
+
+JSON-safety is a runtime concern: before forwarding, apiproxy validates each argument with `dsh-session`'s `isJsonValue` and **throws loudly** when one fails, because that is an allowlist composition mistake rather than untrusted input.
+
+### Wire contract (apiproxy)
+
+```ts ignore-check
+| { type: 'host/remote-event'; event: string; args: JsonValue[] }
+```
+
+The zod branch keeps `args: z.array(z.unknown())`: the frame arrives from `JSON.parse`, so every element is already a JSON value, and the structural contract belongs to the owner package's `Events` declaration — the same posture the existing `session/projection` frame takes with its `value`.
+
+`events.host()` subscribes by allowlist when the stream opens. Each stream owns its disposers, so no broadcast set or derived invalidation listener is needed.
+
+`api/events.ts` is a wire contract file the browser side also compiles, so every type it references must come from an owner package's **client-safe, type-only subpath**, never the package root. Evidence: importing one type from `@deepseek-ai/dsh-session` root drags the root's `declare module 'cordis' { interface Context { sessions: SessionStore } }` into the Client compilation face and overrides the Client's `ctx.sessions: ISessions`, producing 18 errors in the unrelated `ui-slash` and `ui-conversation`. `JsonValue` therefore needs a re-export from `dsh-session/src/types.ts`.
+
+### The apps/web browser e2e belong to the Host face
+
+The `apps/web/tests/**` e2e type-check in the root **`tsconfig.host.json`**: they boot a real harness in-process and read `ctx.apiProxy`, the Host `SessionStore`'s `get`/`create`/`flush`, and `ctx.sessionProjectionCache`. **Driving a browser at runtime does not make a file part of the Client program** — moving them into the Client aggregate immediately produces 21 errors, because one program cannot hold both faces' merges for the same Context key.
+
+That yields a discipline this design depends on: **when those tests import a value or a type from a Client package, they pull that package's whole project — and every project it references — into the Host build graph**. Four consumers (`ui-settings-general`, `ui-models`, `ui-permission`, `ui-command`) reference `api/remotes`' Client face, and that face cannot compile until Host tsdown has generated `@deepseek-ai/dsh-goal/remote`. The result is a build-order deadlock: Host tsc needs the Client face, which needs the generated artifact, which Host tsdown produces after Host tsc.
+
+The few Client-owned symbols are therefore **mirrored** on the test side (`scaffold.ts` exports the mirrored welcome-notice constants; the two chat e2e keep importing `dsh-client-runtime/client` because the `runtime` project is already in the Host graph), which lets those four consumers leave the Host graph. The 15 Client project references in `apps/cli/tsconfig.json` lost their owner-map role and are gone. Each mirrored value matches its source verbatim; a drift shows up as a missed selector or an unsuppressed notice, both loud failures.

+| Root `tsconfig.base.json` | Client-safe `paths` entries for settings, credentials, llm, agent-presets, and api-remotes types point at the **source** plane |
+| `dsh-commands` / `dsh-settings` / `dsh-credentials` / `dsh-llm` / `dsh-agent-presets` | Each forwarded `interface Events` member lives in the owner's client-safe `./types`; agent-presets moves its previous domain vocabulary to `preset.ts` so the exported file itself remains `types.ts` |
+| `host/apiproxy` | `HostFrame` gains `host/remote-event` and loses the five dedicated passthrough or invalidation variants with their zod branches; `events.host()` subscribes by allowlist and validates through `assertJsonArgs` |
+| `dsh-session` | `src/types.ts` re-exports `JsonValue` so wire contract files can use the client-safe subpath |
+| `client/runtime` | The five Client-event bridge branches collapse into `ctx.remote.$dispatch(frame.event, frame.args)`, adding a `remote` injection and deleting their duplicated `Events` declarations |
+| Seven consumers | ui-command / ui-model / ui-models / ui-settings-general / ui-permission / ui-agent-preset / ui-skill subscribe through `ctx.remote.$on(...)`, following `ui-goal`'s precedent for the type-only facade import and the `'remote'` injection |
+| `client/connection` | The fixture's `emitHost` produces `host/remote-event` |
+| `apps/web/tests` + `apps/cli` | Client symbols mirrored on the test side (see above); `apps/cli/tsconfig.json` drops its 15 Client project references |
+
+## Alternatives considered
+
+**Open a general downlink channel for Remote events** (the push counterpart of `ctx.connection.rpc`, a third WebSocket). This best matches "Connection owns the carrier, the Gateway never touches transport", but it means a new stream in the Host downlink, `WebApiClient`, `ConnectionController`, the fixture, and the web e2e — a cost out of proportion to this change. Reusing the host stream costs a temporary tenancy inside a legacy frame union; when that stream moves, the wrapper moves with it and the consumer contract does not change.
+
+**Declare a separate `TypeRTRemoteEventMap` in type-meta and let owner packages merge into it.** The consumer key set would equal exactly "events declared remotely deliverable", but every signature would be written a second time outside cordis `Events`, requiring a bidirectional `extends` proof to stop the two from drifting, plus a new type-meta dependency for three owner packages. Sharing the one `Events` declaration makes that equivalence structural, so the table is not created.
+
+**Have the typert generator project Host `Events` declarations** (codec, `.d.ts`, declaration map, like `/remote`). The generator already analyzes Host events, but it cannot see projection or redaction intent, and it would change the generator and the build surface. Verbatim forwarding needs no projection.
+
+**Give forwardable events a payload projection function** (a `{ name, project, zod }` forwarding table). This could fold the two model-directory inputs into one derived invalidation and also cover workspace view derivation, at the cost of hand-aligning projection logic with payload types — the central table the method side just removed.
+
+**Move the apps/web browser e2e into the Client aggregate.** "Client tests belong to the Client face" looks right and fails immediately with 21 errors: those tests use Host services, and in the Client program `ctx.sessions` is `ISessions`.
+
+**Split `directory-picker-browse`/`-native` into Host and Client faces** so no Client package reaches the Host graph. The direction is right — they are genuinely unsplit dual-half packages — but the change lands in another owner's packages and buys only a cleaner build graph; once this design mirrors the Client symbols on the test side, it no longer needs the split. **Assessed and declined.**
+
+## Verification
+
+What pins this behavior:
+
+- A real composition test puts one `host/remote-event` frame on the real host stream per Host emit, with `event` the Host name and `args` equal element for element.
+- Type-level negatives reject three candidate classes: a name that is not an event, a Scope-bound event (`goal/changed`), and an event whose return is not `void`. `$on('slots/changed', …)` (Client-local) and `$on('skills/change', …)` (declared but unselected) both fail to compile, so `$on`'s key surface equals the allowlist.
+- On the consumer side, `$on('settings/document-updated', …)` resolves `ns` as `SettingsNamespace`: the brand survives the wire.
+- `$on`'s disposer belongs to the calling fiber, and two registrations of one function object retire independently — a table keyed on listener identity would collapse them, so subscriptions are addressed by registration.
+- Delivery contains a listener that throws AND one that rejects a returned promise: the declared return is `void`, so nobody awaits an async listener, and its rejection would otherwise escape this containment entirely. Delivery iterates a snapshot, so subscribing or disposing mid-frame cannot change who receives that frame.
+- `assertJsonArgs` is unit-tested directly rather than by driving a malformed emit through the event bus: a typed `ctx.emit` cannot construct one, since every allowlisted event has a statically JSON-safe payload.
+- The five dedicated `HostFrame` variants, five Client-side aliases, and their bridge branches are absent. The model directories observe both owner inputs, while command, skill, and session-row consumers observe the preset owner's committed-selection event.
+
+## Consequences
+
+- **Tenancy inside a legacy frame union.** The contract lives in apiproxy's `HostFrame`, so a reader may assume apiproxy owns Remote events. The frame's JSDoc names `api-remotes` as the allowlist owner, and apiproxy's README records the tenancy under known limitations. When the host stream moves off that package, the wrapper moves with it and the consumer contract does not change.
+- **Two files break api/remotes' face-disjointness contract.** `src/remote-events.ts` and `src/types.ts` belong to both projects, so each emits an identical declaration into the shared `lib/types`. Content is byte-identical and the `.tsbuildinfo` files stay separate, so this is harmless in practice; the README's build-boundary section states the exception and its cause (the `paths` entry points at source).
+- **The carrier handoff is developer-visible.** Any Client plugin holding `ctx.remote` can call `$dispatch` and synthesize a forwarded event. That exposure predates the verb — `ctx.emit` was equally reachable while an internal event relayed the frame — and matches what `connection/reset` already allows for a fabricated reconnect; the Client is one trust domain. Tests pin the handoff-to-`$on` conversion and do not pretend the port authenticates its caller.
+- **A malformed argument fails in the emitter's containment, not at load.** `assertJsonArgs` throws inside the forwarding listener, so the emitting seam's listener containment logs it and drops that frame: loud in the Host log rather than at load or at the emit point.
+- **Mirrored test values can drift.** Nothing mechanically checks the Client constants mirrored in `apps/web/tests` against their source; the safety net is only that a drift misses a selector. The rule lives in `apps/web/tests/README.md` and is held by review — a grep-level gate was considered and deliberately skipped.
+- **Capabilities given up.** No projected or redacted payloads, no Scope-bound events (`agentCtx.remote.$on`), and no replay on reconnect — these are pure invalidation signals, and `connection/reset` already covers refetching after a reconnect. The mux stream's session events, answerable frames, and snapshot baselines stay out of scope.
+- **Client packages remain in the Host graph.** Twelve projects (`connection`, `runtime`, `ui-slots`, and kin) still reach it through the unsplit `directory-picker-browse`/`-native` pair and `api/gateway → client/connection`. They compile and no longer implicate api/remotes' Client face, so they did not block this change; splitting those packages would remove a few but was assessed and declined. The two chat e2e importing `dsh-client-runtime/client` rely on `runtime` already being in that graph — incidental, not a guarantee.
+- **The invariant companion holds no runtime check.** An earlier revision asserted the dispatch shape (`thisArg === null`, `mode === 'emit'`) over the live event bus, which coupled the companion to the allowlist value and made rolldown hoist it into a third bundle chunk the mechanical publication list does not carry. The Host face's `TypeRTForwardableEvent` assertion already refuses both deviations at compile time, so the companion is an explained empty installer.

+# Agent Note: Remote 事件投递（ctx.remote.$on）
+
+Status: implemented
+
+[English](2026-08-10-remote-event-delivery.md) | 中文
+
+## 问题
+
+[TypeRT Remote 方法调用](../../implemented/architecture/2026-08-02-typert-remote-method-calls.md)只覆盖「一次请求一个结果」的定向调用，明确把 Session 事件流与有状态交互留在别处；Host 向消费端的**单向事件推送**因此仍然全部压在遗留的 API Proxy 上。
+
+Host 拥有 `agent-preset/selected`、`commands/change`、`credentials/updated`、`llm/adapters-updated`、`settings/document-updated` 这五条单向事件；它们既不依赖 AgentScope，载荷也本来就是 JSON。过去每条都要穿过 host cordis 事件、apiproxy 手写帧、client/runtime 手写桥和 Client 事件别名才能抵达 UI，而这些层没有陈述 owner 事件之外的新事实。
+
+那份重复声明还是**有损**的：client 侧写成 `settings/changed(ns: string)`，brand 类型在这一跳被拍平成裸 `string`，与 Remote 方法侧「消费端类型指向业务包唯一符号」的既有契约相反。
+
+## 决策
+
+消费端 Remote 面持有一个单向事件订阅动词 `ctx.remote.$on(event, listener)`；**名单驱动、原样转发**：
+
+- `packages/api/remotes/src/remote-events.ts` 持有一份可转发 host 事件名单，它同时是「消费端能订阅什么」的唯一控制点。旁边的 `src/types.ts` 由它派生类型投影并填充 selection 座位，按包约定保持纯类型。两个文件**都同时列进本包 host 与 client 两个 face 的 `files`**，两侧读同一份。
+- wire 上的事件名 **就是 host cordis 事件原名**（`settings/document-updated`），不加 `host/` 前缀；载荷 **就是 host 的实参列表**，逐元素原样过 JSON，无投影、无脱敏、无改名。
+- 载体**寄生现有 host 流**：`HostFrame` 加一个包裹帧 `host/remote-event`，不新开下行通道。
+- 事件**签名**不另立表：owner 包把自己的 cordis `Events` 声明搬进 client-safe 的 `./types` 纯类型出口，两侧读**同一份**——`$on` 的 listener 类型就是 `Events[Event]` 本身。「原样」不需要证明，是构造性成立的。
+- 但**只借 cordis 的类型形状，不接 cordis 的事件系统**：投递语义、注册表、异常处置全归 TypeRT 自己。
+
+一条 `Events` 条目若签名里够到了 host-only 符号（Service、`Agent`、Context 等），处理方式是**把代码拆到能干净落进 `./types` 为止**；不接受「一半留 index、一半搬走」的分裂声明，也不接受在 `./types` 里造结构等价的影子类型。这五个包都不需要拆：它们的条目只够到纯类型。agent-presets 把原词汇模块改名为 `preset.ts`，让导出的 `types.ts` 专门承载 client-safe 事件声明。
+
+五条事件全部走这条路径，专用帧与 Client 别名都已删除。模型消费方直接订阅 `llm/adapters-updated` 和 `settings/document-updated`；preset 消费方订阅 `agent-preset/selected`。真正需要投影或去重的数据仍保留专用帧。
+
+`skills/change`、`tools/change`、`system-prompt/change` 是同形状的纯失效事件但目前**没有任何消费者**，按「每个抽象都要有当前 owner 与需求」不进名单，只作为扩展位记录在此。
+
+### 消费端契约（dsh-type-meta）
+
+type-meta 加一个**形状谓词**、一个**选择座位**和 `TypeRTClientRemote` 的**一个**成员；零运行时代码：
+
+```ts
+import type { Events } from '@deepseek-ai/cordis'
+
+/** Cordis events shaped for one-way remote delivery: no Scope binding, void return. */
+export type TypeRTForwardableEvent = {
+  [Event in keyof Events]: unknown extends ThisParameterType<Events[Event]>
+    ? ReturnType<Events[Event]> extends void ? Event : never
+    : never
+}[keyof Events]
+
+/** The Host assembly's forwarding selection; api/remotes' allowlist fills it, no other package does. */
+export interface TypeRTRemoteEventSelection {}
+
+/** `$on`'s legal keys: selected, and present in the current compilation face. */
+export type TypeRTRemoteEvent = Extract<keyof Events, keyof TypeRTRemoteEventSelection>
+```
+
+```ts ignore-check
+/** Subscribe to one forwarded Host event; the returned disposer belongs to the calling fiber. */
+$on<Event extends TypeRTRemoteEvent>(event: Event, listener: Events[Event]): () => void
+```
+
+`Events` 按程序解析：host 程序里是 host 事件全集，client 程序里是 client 编译面看得见的那些——同一个谓词在两侧各自成立，不需要把 host 声明拖进 client。
+
+**契约把消费动词与载体交接分开**：消费方用 `$on` 订阅，持有 host 帧 sink 的一方用 `$dispatch` 把解码后的帧交进来。它**不能**是一个跨插件的模块级函数：client bundle 纯度门禁（`packages/client/tsdown.client.ts`）只放行 `CLIENT_EXTERNALS`、`INLINE_SAFE` 那层 wire 契约与 `/remote` 生成物三类值导入，而靠 inline 绕过会把 `ClientRemoteService` 复制一份进 runtime bundle、令 `instanceof` 恒假。cordis 服务方法正是该门禁指定的协作形态：
+
+```ts ignore-check
+$dispatch(event: string, args: readonly unknown[]): void
+```
+
+持有 host 帧 sink 的 client/runtime 直接调用它，帧不经中转事件即到达订阅表。`event` 形参是 `string` 而非 `TypeRTRemoteEvent`：这是 wire 边界，收到无人订阅的名字即静默丢弃。
+
+投递语义与 cordis 事件系统不共用实现：只有单向投递，没有 waterfall / bail / parallel / serial 模式，也没有 `@mode` 概念（`ReturnType extends void` 是这条纪律的静态表达）；不绑 `this`；没有 `EventOptions`、`prepend`、优先级；按注册顺序逐个调用，单个 listener 抛错就地隔离并记日志——它绝不能拖垮帧泵（沿用 `ConnectionController` 对 sink 异常的既有处置）。
+
+### 名单：两个 face 共读的同一份声明
+
+`packages/api/remotes/src/remote-events.ts` 同时列进 `tsconfig.host.json` 与 `tsconfig.client.json` 的 `files`，是名单的**唯一家**；`src/types.ts` 由它派生类型面：
+
+```ts
+// remote-events.ts — the value
+export const API_REMOTE_FORWARDED_EVENTS = [
+  'agent-preset/selected',
+  'commands/change',
+  'credentials/updated',
+  'llm/adapters-updated',
+  'settings/document-updated',
+] as const
+
+// types.ts — the type face, derived
+export type ApiRemoteForwardedEvent = typeof API_REMOTE_FORWARDED_EVENTS[number]
+
+declare module '@deepseek-ai/dsh-type-meta' {
+  interface TypeRTRemoteEventSelection extends Record<ApiRemoteForwardedEvent, true> {}
+}
+```
+
+于是**加一个事件只改这一行数组**：类型投影、`$on` 的键面、host 的转发循环全部从它派生。`ctx.remote.$on('slots/changed', …)`（client 本地事件）或 `$on('skills/change', …)`（名单没开）都是**编译错误**。
+
+host 半再加一处形状断言，把 host 事件词汇的约束落到同一份名单上：
+
+```ts ignore-check
+API_REMOTE_FORWARDED_EVENTS satisfies readonly TypeRTForwardableEvent[]
+```
+
+写成表达式语句而不是命名常量：后者会被 `noUnusedLocals` 判为未使用（下划线前缀只豁免参数）。它卡住三件事：**名字合法**（谓词以 `keyof Events` 为基）、**不绑 Scope**（`goal/changed` 那族的 `ThisParameterType` 不是 `unknown`，被排除——「不依赖 AgentScope」的静态表达）、**单向**（非 `void` 返回的 waterfall/bail 形状被排除）。
+
+**「原样」不在任何地方证明，而是构造性成立**：`$on` 的 listener 类型取自 owner 包 `./types` 里那一份 cordis `Events` 声明，host 转发读的是同一份，不存在可以彼此偏离的第二份声明。
+
+载荷 JSON-safe 交给运行时：apiproxy 转发前用 `dsh-session` 的 `isJsonValue` 逐元素校验，不合格**抛错 fail loud**（这是名单配置错误，不是外部输入）。
+
+### 线协议（apiproxy）
+
+```ts ignore-check
+| { type: 'host/remote-event'; event: string; args: JsonValue[] }
+```
+
+zod 侧 `args: z.array(z.unknown())`：帧本身来自 `JSON.parse`，元素必然已是 JSON 值，结构契约由 owner 包的 `Events` 声明承担——与既有 `session/projection` 帧的 `value` 同 posture。
+
+`events.host()` 打开时按名单挂监听；每条流自持 disposers，无需新增广播集合或派生失效 listener。
+
+
+`api/events.ts` 是浏览器侧也要编译的 wire 契约文件，所以它引用的每个类型都必须走 owner 包的 **client-safe type-only 子路径**，绝不能走包根出口。实证：从 `@deepseek-ai/dsh-session` 根引一个类型，就把根出口的 `declare module 'cordis' { interface Context { sessions: SessionStore } }` 拖进 client 编译面、把 client 的 `ctx.sessions: ISessions` 顶掉，在完全无关的 `ui-slash` / `ui-conversation` 里炸出 18 条错。`JsonValue` 因此需要 `dsh-session/src/types.ts` 补一条 re-export。
+
+### apps/web 的 browser e2e 属于 Host 面
+
+`apps/web/tests/**` 那批 e2e 在**根 `tsconfig.host.json`** 做类型检查：它们在进程内起真 harness、直接摸 `ctx.apiProxy`、host `SessionStore.get/create/flush`、`ctx.sessionProjectionCache`。**运行时用浏览器 ≠ 类型上属于 client 程序**——把它们搬进 client 聚合会立刻报 21 条错，因为一个 program 装不下两个 face 对同一个 Context key 的合并。
+
+由此得到一条对本设计要紧的连带纪律：**这些测试从客户端包 import 值或类型，会把该包的整个 project——以及它引用的每个 project——拖进 Host 构建图**。`ui-settings-general`/`ui-models`/`ui-permission`/`ui-command` 四个消费者 references `api/remotes` 的 client face，而该 face 必须等 host tsdown 生成 `@deepseek-ai/dsh-goal/remote` 才能编译，于是形成构建期死锁：host tsc → api/remotes client face → `goal/remote` → host tsdown → 排在 host tsc 之后。
+
+所需的客户端符号在测试侧**镜像**了一份（`scaffold.ts` 导出镜像后的 welcome-notice 常量，两个 chat e2e 直接引 `dsh-client-runtime/client` 因为 `runtime` 工程本来就在 host 图里），从而让那 4 个消费者离开了 host 图；`apps/cli/tsconfig.json` 里 15 条 client 工程引用随之失去 owner-map 职责，已一并删除。镜像值与源逐字一致，漂移的表现是选择器失配或通知未被抑制，都是响亮失败。
+
+### 改动清单
+
+| 位置 | 改动 |
+|---|---|
+| `dsh-type-meta` | `src/types.ts` 加 `TypeRTForwardableEvent`、`TypeRTRemoteEventSelection`、`TypeRTRemoteEvent`；`TypeRTClientRemote` 增 `$on` 与 `$dispatch`。纯类型，零运行时 |
+| `api/gateway` client 半 | `ClientRemoteService` 实现 `$on`（订阅按注册项寻址、`ctx.effect` 归属调用方 fiber）与 `$dispatch`（快照后按注册顺序派发，收容抛出或拒绝的 listener） |
+| `api/remotes` | 新增 `src/remote-events.ts`（名单值）与 `src/types.ts`（类型投影 + 选择座位），两者都双列进两个 face 的 `files`；`./types` 出口 + `files` 补 `lib/types/**/*.js`；host 半加形状断言并 `import type {}` 三个 owner 包的 `./types`；client 半 `export type {}` 那三个 `./types` 与 `@deepseek-ai/dsh-api-gateway/client` |
+| 根 `tsconfig.base.json` | 加 `dsh-settings/types`、`dsh-credentials/types`、`dsh-api-remotes/types` 三条 `paths`，全部指向**源**平面 |
+| `dsh-commands` / `dsh-settings` / `dsh-credentials` | `interface Events` 子块移入各自 client-safe 的 `./types`（settings/credentials 新建该出口，brand 与纯类型一并移入，index 继续 re-export 并留住构造器；`files` 补 `lib/types/**/*.js`） |
+| `host/apiproxy` | `HostFrame` 增 `host/remote-event`、删除五个专用变体及其 zod；`events.host()` 按名单挂监听并通过 `assertJsonArgs` 校验 |
+| `dsh-session` | `src/types.ts` 补 `export type { JsonValue }`，让 wire 契约文件能走 client-safe 子路径 |
+| `client/runtime` | 五条 Client 事件桥分支收敛为 `ctx.remote.$dispatch(frame.event, frame.args)`，并删除重复声明 |
+| 5 个消费者 | ui-command / ui-models / ui-settings-general / ui-permission / ui-agent-preset 改订 `ctx.remote.$on(...)`；照 `ui-goal` 先例 type-only 引 `@deepseek-ai/dsh-api-remotes/client` 并把 `'remote'` 加进 `inject` |
+| `client/connection` | fixture 的 `emitHost` 造 `host/remote-event` |
+| `apps/web/tests` + `apps/cli` | 客户端符号镜像（见上节）；`apps/cli/tsconfig.json` 删 15 条 client 工程引用 |
+
+## 备选方案
+
+**给 Remote 事件新开一条通用下行通道**（`ctx.connection.rpc` 的推送对偶，第三条 WebSocket）。最符合「Connection 独占载体、Gateway 不碰传输」；但要同时改 host 下行、`WebApiClient`、`ConnectionController`、fixture 与 web e2e 各一条流，代价与本次收益不匹配。寄生 host 流的代价是新契约暂时寄居在 legacy 帧联合里——host 流将来整体搬家时它随之搬走，消费端契约不变。
+
+**在 type-meta 立一张独立的 `TypeRTRemoteEventMap`，让 owner 包 declare-merge 进去**。消费端键集会精确等于「被声明为可远程投递的事件」；代价是每条事件的签名要在 cordis `Events` 之外**再写一遍**，于是需要一条双向 `extends` 的等价性证明来防漂移，还要给三个 owner 包新增 type-meta 依赖。共用同一份 `Events` 声明让等价性变成构造性成立，这张表因此不立。
+
+**让 typert generator 从 host `Events` 声明生成事件投影**（codec + `.d.ts` + 声明映射，与 `/remote` 同族）。generator 已经在分析 host 事件；但它拿不到投影与脱敏语义，且要动生成器与构建面。原样转发这条路本就不需要投影。
+
+**给可转发事件加载荷投影函数**（`{ 事件名, 投影, zod }` 转发表）。能一举覆盖 `models-changed` 的 fan-in 与 workspace 的 view 派生；代价是投影逻辑与载荷类型手工对齐，回到方法侧刚刚消灭的中心表形态。
+
+**把 apps/web 的 browser e2e 搬进 client 聚合**。看似「客户端测试归客户端面」，实测立刻 21 条错：它们用 host 服务，而 client 程序里 `ctx.sessions` 是 `ISessions`。已否。
+
+**给 `directory-picker-browse`/`-native` 做 host/client 双 face 切分**，从根上让客户端包不进 host 图。方向正确（它们确实是未切分的双半包），但改动落在别人属地，而收益只是「构建图更干净」——本设计在测试侧镜像客户端符号之后已经不需要它。**已评估不做**。
+
+## 验证
+
+钉住该行为的东西：
+
+- 一个真组合测试：host 每 emit 一次，真实 host 流就出一帧 `host/remote-event`，`event` 为 host 原名、`args` 与实参逐元素相等。
+- 类型层负例拒绝三类候选：不是事件的名字、绑 Scope 的事件（`goal/changed`）、返回值非 `void` 的事件。`$on('slots/changed', …)`（client 本地事件）与 `$on('skills/change', …)`（已声明但未选中）都编译失败——因此 `$on` 的键面恰好等于名单。
+- 消费端 `$on('settings/document-updated', …)` 把 `ns` 解析为 `SettingsNamespace`：brand 穿过 wire 存活。
+- `$on` 的 disposer 归属调用方 fiber；同一个函数对象订阅两次时两条注册各自独立退订——按 listener 身份做键的表会把它们合并，所以订阅按注册项寻址。
+- 投递同时收容抛出的 listener 与拒绝所返回 promise 的 listener：声明返回值是 `void`，没人 await 异步 listener，其拒绝否则会完全逃出这层收容。投递遍历快照，因此派发中订阅或退订都不会改变本帧的接收者集合。
+- `assertJsonArgs` 直接单测，而不是从事件总线造畸形 emit：类型化的 `ctx.emit` 造不出来——名单内每条事件的载荷在静态上都是 JSON-safe 的。
+- 五个专用帧、五条 Client 别名及其桥分支都不存在；各消费方直接观察 owner 事件。
+
+## 后果
+
+- **寄居在 legacy 帧联合里**：契约住在 apiproxy 的 `HostFrame` 中，读者可能误以为 apiproxy 拥有 Remote 事件。该帧的 JSDoc 点名名单归 `api-remotes`，apiproxy README 在 known limitations 记录这项寄居。host 流将来整体搬家时，包裹帧随之搬走，消费端契约不变。
+- **两个文件打破了 api/remotes 的 face 互斥约定**：`src/remote-events.ts` 与 `src/types.ts` 同属两个工程，各自向共享的 `lib/types` 发射一份相同声明。内容逐字节相同、`.tsbuildinfo` 各自独立，实践上无害；README 的构建边界节陈述了这个例外及其成因（`paths` 指向源码面）。
+- **载体交接是开发者可见的**：任何持有 `ctx.remote` 的 client 插件都能调 `$dispatch` 合成一条转发事件。这个暴露面早于该动词存在——先前由内部事件中转帧时，`ctx.emit` 同样可达——与 `connection/reset` 可被伪造成重连同一量级（client 是单一信任域）。测试只钉「交接到 `$on` 的转换」，不假装该端口鉴别调用方。
+- **畸形实参在发射方的收容里失败，而非加载期**：`assertJsonArgs` 在转发监听内抛出，因此由发射 seam 自己的 listener 收容记录并丢弃该帧——响亮地出现在 host 日志里，而不是加载时或 emit 点。
+- **测试侧镜像值可能漂移**：没有任何机制核对 `apps/web/tests` 中镜像的 client 常量与其源；安全网只是漂移会让选择器失配。规则写在 `apps/web/tests/README.md`，由 review 守；grep 级门禁经评估后刻意不做。
+- **放弃的能力**：不支持投影或脱敏载荷、不支持 Scope 化事件（`agentCtx.remote.$on`）、重连不重放——这些都是纯失效信号，且 `connection/reset` 已覆盖重连后的重新拉取。mux 流的会话事件、可应答帧与快照基线不在范围内。
+- **仍有 client 包留在 host 图里**：12 个工程（`connection`、`runtime`、`ui-slots` 等）经未拆分的 `directory-picker-browse`/`-native` 与 `api/gateway → client/connection` 仍可达 host 图。它们都能编译且不再牵连 api/remotes 的 client face，因此没有阻塞本次改动；拆分那些包能减少几个，但经评估后不做。两个 chat e2e 直接引 `dsh-client-runtime/client` 依赖 `runtime` 本来就在图里——属偶然而非保证。
+- **invariant companion 不做运行期检查**：早先的修订曾在活事件总线上断言投递形状（`thisArg === null`、`mode === 'emit'`），这让 companion 与名单值耦合，并使 rolldown 把它提成第三个 bundle chunk——而机械推导的发布文件清单并不携带它。host 面的 `TypeRTForwardableEvent` 断言在编译期已拒绝这两种偏离，因此该 companion 是一个带说明的空 installer。

+# Agent Note: Trim the command-line seams to existing interfaces
+
+Status: implemented
+
+English | [中文](2026-08-11-cmdline-seam-trim.zh.md)
+
+## Problem
+
+The app-owned command line ([note](2026-08-06-app-owned-command-line.md)) shipped with three seams that were wider than their consumers needed: a vendored in-memory row-activation state machine (`Entry.enableRuntime` plus `enableRow` exported from `dsh-cmdline`, a command-line package owning a Loader concept) whose only purpose was the `--dev` conditional reload row, a vendored `EntryConfigResolver` protocol symbol whose only implementer was Include, and a launcher that still recognized the `headless-runner` row to pick SIGTERM exit codes, gate user-patch watching, and provide a `headlessIo` seam duplicating `ctx.appExit`.
+
+## Decision
+
+Express all three with interfaces that already exist:
+
+- **No conditional dev row.** The reload chain stops being conditional: `dsh-web-app` mounts the `client-hmr` row unconditionally and `--dev` is deleted, along with the web runtime's `mode` config, the mode-forked prompt contract, and the `DSH_WEB_MODE` bash variable. Without a rebuild watcher (`pnpm run dev:web`) rewriting client bundles, the chain polls unchanged files and stays idle, so the always-on row costs one stat-poll interval and an SSE route. `Entry.enableRuntime`, its two state fields, and `enableRow` are deleted with nothing replacing them.
+- **Tree-carrier config.** Include declares the existing `EntryGroup.key` marker instead of implementing `EntryConfigResolver`; the Loader hook keeps every tree carrier's config literal. Include's own `path` loses `!!js` support — no configuration ever used it, and the pinning test now asserts the literal tree-carrier contract instead.
+- **Launcher app-knowledge.** The launcher recognizes no app row. SIGTERM is a supervisor's ordinary stop request and exits 0 on every surface (SIGINT stays 130); the launcher cannot know whether the app considered its work complete, and the previous 143 depended on naming the headless row. Every boot watches its user patch layers — a one-shot surface exits through bounded shutdown, which disposes the watchers before the loop drains. The headless runner exits through `ctx.appExit` like any other app; its output streams are a package-internal `internals` test seam, and `ctx.headlessIo` is deleted.
+
+## Alternatives considered
+
+- **Keeping `enableRuntime` but moving `enableRow` out of `dsh-cmdline`**: relocation fixes the package boundary but keeps the vendored state machine whose semantics (survives reapplication, rollback on failure) must be re-derived at every upstream sync.
+- **`entry.update({ disabled: null })`**: mutates the entry's serialized options, so the next include reapplication restores `disabled: true` and unmounts the row mid-session.
+- **SIGTERM 143 for one-shot surfaces via an app-registered signal handler**: the launcher's own handler races it for the exit code; winning that race needs a new launcher interface, which is the cost this change removes.
+- **Keeping `--dev` with the row created at runtime**: an interim state of this change; it still needed a mode fork in the prompt contract, a `DSH_WEB_MODE` variable, and creation-versus-user-row arbitration, all to avoid an idle poll whose cost is negligible.
+
+## Consequences
+
+- A deployment that supervises `dsh --profile headless` with SIGTERM now observes exit 0 instead of 143; the caller sent the signal and sees no answer on stdout.
+- The reload chain runs in every `dsh web` process; a deployment that must not expose `/plugins/events` disables the `client-hmr` row in its patch layer.
+- One-shot runs mount the config-watch rows they previously skipped, costing a few milliseconds of startup.
+- The vendored Loader/Include divergence shrinks by one protocol symbol and one state machine, and `rescope-vendor:check` passes again (the modification log's rescope entry is restored to the position its exact-edit anchor requires).

+# Agent Note：把命令行接缝收窄到既有接口
+
+Status: implemented
+
+[English](2026-08-11-cmdline-seam-trim.md) | 中文
+
+## 问题
+
+应用自有命令行（[笔记](2026-08-06-app-owned-command-line.md)）交付时带着三条比其消费者所需更宽的接缝：一台 vendored 的内存行激活状态机（`Entry.enableRuntime`，外加从 `dsh-cmdline` 导出的 `enableRow` —— 一个命令行包拥有了 Loader 概念），其唯一用途是 `--dev` 条件重载行、一个只有 Include 一个实现者的 vendored `EntryConfigResolver` 协议符号，以及仍然识别 `headless-runner` 行的启动器 —— 用它选择 SIGTERM 退出码、门控用户 patch 监视，并提供与 `ctx.appExit` 重复的 `headlessIo` 接缝。
+
+## 决策
+
+三者全部改用已经存在的接口表达：
+
+- **不再有条件 dev 行。** 重载链不再是条件性的：`dsh-web-app` 无条件挂载 `client-hmr` 行，`--dev` 连同 web runtime 的 `mode` 配置、按模式分叉的提示词约定和 `DSH_WEB_MODE` bash 变量一并删除。没有重建 watcher（`pnpm run dev:web`）改写客户端 bundle 时，链路轮询到的文件从不变化、保持空闲，因此常开的行只花费一个 stat 轮询间隔和一条 SSE 路由。`Entry.enableRuntime`、它的两个状态字段和 `enableRow` 删除后无任何替代物。
+- **树载体配置。** Include 改为声明已有的 `EntryGroup.key` 标记，不再实现 `EntryConfigResolver`；Loader 钩子让每个树载体的配置保持字面值。Include 自己的 `path` 失去 `!!js` 支持 —— 从未有配置用过它，固定该行为的测试改为断言字面值树载体约定。
+- **启动器的应用知识。** 启动器不再识别任何应用行。SIGTERM 是监督进程的普通停止请求，在所有 surface 上以 0 退出（SIGINT 仍为 130）；启动器无从知道应用是否认为工作已完成，而之前的 143 依赖于点名 headless 行。每次启动都监视用户 patch 层 —— 一次性 surface 经由有界关闭退出，关闭会先 dispose 监视器再排空事件循环。headless runner 像任何应用一样经 `ctx.appExit` 退出；其输出流是包内 `internals` 测试接缝，`ctx.headlessIo` 删除。
+
+## 考虑过的替代方案
+
+- **保留 `enableRuntime` 但把 `enableRow` 移出 `dsh-cmdline`**：搬迁修正了包边界，却保留了 vendored 状态机，其语义（在重新应用后仍生效、失败时回滚）在每次上游同步时都要重新推导。
+- **`entry.update({ disabled: null })`**：改写条目的序列化选项，下一次 include 重新应用会恢复 `disabled: true` 并在会话中途卸载该行。
+- **通过应用注册的信号处理器为一次性 surface 保留 SIGTERM 143**：启动器自己的处理器会与它竞争退出码；要赢得竞争需要新的启动器接口，而这正是本次变更要移除的成本。
+- **保留 `--dev`、改为运行时创建该行**：本次变更的中间形态；它仍需要提示词约定里的模式分叉、`DSH_WEB_MODE` 变量，以及创建与用户自有行之间的仲裁，而这一切只为省下一个成本可忽略的空闲轮询。
+
+## 后果
+
+- 用 SIGTERM 监督 `dsh --profile headless` 的部署现在观察到退出码 0 而非 143；信号是调用方自己发的，且 stdout 上没有答案。
+- 重载链在每个 `dsh web` 进程中运行；不得暴露 `/plugins/events` 的部署应在其 patch 层禁用 `client-hmr` 行。
+- 一次性运行会挂载之前跳过的配置监视行，启动多花几毫秒。
+- vendored Loader/Include 偏差减少一个协议符号和一台状态机，`rescope-vendor:check` 重新通过（修改日志的 rescope 条目回到其精确编辑锚点要求的位置）。

 ## Decision
 
-The ordinary `dsh web` composition mounts the Web bundle's `web-runtime` plugin, which publishes one canonical loopback URL and its actual runtime mode as both model-visible orientation and managed shell facts. The `app:web-surface` prompt section says that unqualified references identify this GUI and names the URL; `DSH_WEB_URL` and `DSH_WEB_MODE=production|development` carry the same facts into every foreground or managed background bash call. The section preserves the no-implicit-DOM, route, or screenshot boundary and does not claim that a LAN alias equals the browser's literal address. A complete-prompt profile sets the row's `surfaceContext` to false and receives neither the prompt section nor the managed variables; the Web launcher uses the same setting to suppress its source-checkout prompt section.

Shell and other plain-package changes still require rebuild plus refresh. An agent in production mode explains both commands when a user requests no-refresh updates; it does not launch a replacement GUI unless asked.

 ## Verification

 Presets moved the rows that decide what a session's `/` menu contains. The Web composition disables host-plane `skill-local`, `tool-skill`, `plan-mode`, and `command-compact`; a preset supplies them, so which commands and skills exist is a property of the session's composition rather than of the deployment.
 
-Both browser catalogs cache per session — `CommandDirectory` in `dsh-client-ui-command`, the single-flight fetch map in `dsh-client-ui-skill` — and the composer warms both at scope birth, under whatever preset the session was created with. The hero chip then lets the user recompose the still-blank session, and neither cache had an invalidation edge for that: `commands/changed` is registry-wide and `connection/reset` needs a reconnect. `agentPresets.recompose` re-parents the agent's scope onto a standing mount that may already exist, so it registers nothing and the registry-wide signal never fires for it.

 The menu therefore kept serving the composition the session no longer ran. Switching down left `compact`, `plan`, and every project skill listed; switching up left the narrower catalog — the four host-plane rows and the client's own `model` contribution — with no skills at all, which is what the bug report described. The catalog only healed when an unrelated registry change or a reconnect happened to invalidate it.
 
 ## Decision
 
-The switch's commit point is the logged `agent-preset/selected` event. The host stream frames it as `host/session-preset-changed { sessionId, agentPreset }`, the browser runtime bridges that frame to the typed `session/preset-changed` ctx event beside the registry-invalidation bridges it already owns, and each catalog owner drops its own entry for that session: `ui-command` soft-refreshes the key (the old snapshot keeps serving the open menu until the new one lands), `ui-skill` invalidates it (aborting an in-flight prewarm, so a warm racing the switch cannot publish the stale catalog).
+The switch's commit point is the logged `agent-preset/selected` event. The preset owner re-emits that commit as the client-safe cordis owner event `agent-preset/selected(sessionId, agentPreset)`, the host stream forwards it verbatim, and each catalog subscribes directly through `ctx.remote.$on`: `ui-command` soft-refreshes the key (the old snapshot keeps serving the open menu until the new one lands), while `ui-skill` invalidates it (aborting an in-flight prewarm, so a warm racing the switch cannot publish the stale catalog).
 
-The frame is per session and carries no catalog, only the preset id — which the manager folds into the session row, because the `agentPresets.select` echo reaches only the client that issued the switch and the row is what the session header labels itself from (and what the hero chip compares the next pick against).

-Deriving the frame from the logged event rather than from the RPC handler's return keeps one authority for "this session's composition changed": every connected client observes the switch, not only the tab that issued it, and a client that is not the switcher never has to infer it from a registry signal that will not come.

 Pasted or dropped raster images are the Web composer's first consumer of a durable attachment capability. Unsent files remain temporary client-owned draft state. The host validates and durably commits every accepted user image before appending its message event. A provider adapter that produces structured image output must durably commit the output before appending its assistant block. Canonical user and assistant content contains only role-neutral `ImageBlock` references.
 
-Version one supports PNG, JPEG, WebP, and GIF paste and drag-and-drop, image-only or mixed prompts, historical user and assistant image rendering, and original-image preview on double-click. File picking, generic files, PDF, audio, video, image copying, and a custom context menu remain separate follow-ups.
+Version one supports PNG, JPEG, WebP, and GIF paste and drag-and-drop, image-only or mixed prompts, historical user and assistant image rendering, and original-image preview on a single click (display and interaction specifics superseded in part by the [attachment-display alignment note](2026-08-11-web-attachment-display-alignment.md)). File picking, generic files, PDF, audio, video, image copying, and a custom context menu remain separate follow-ups.
 
 ### Product behavior
 
 - Pasting or dropping one or more supported images adds ordered thumbnails above the textarea without inserting placeholder text. Dragging files over the composer highlights the drop target.
 - The same resident `InputBar` renders the rail in both blank-session Hero and active-session layouts. The rail is hidden when empty and scrolls horizontally instead of widening the composer.
-- Each approximately 72-by-72-pixel thumbnail has a remove action and opens its original draft image on double-click.
+- Each 64-by-64-pixel thumbnail carries a hover-revealed remove control inside the card and opens its original draft image on a single click; overflow pages with edge arrows instead of a visible scrollbar.
 - A prompt may contain text and images or images only. Pure text paste remains native browser behavior; mixed clipboard content inserts its text normally while adding its files to the rail, and file-only paste prevents default browser handling. File drops on the composer always prevent browser navigation and report unsupported files locally.
 - A failed send restores the complete text and image draft without clobbering text or images added while the request was in flight. Removal, successful send, session-scope disposal, rendered-history disposal, and application disposal revoke the object URLs they own.
 - Historical user and assistant images use one `MessageImage` control. Inline images preserve intrinsic aspect ratio, do not upscale, and stay within a 240-by-240-pixel box.
-- Double-clicking a message image opens the stored original in a viewport-bounded modal. Escape, the close control, and backdrop activation close it and restore focus.

 The Pi-AI adapter is the first visual-input route: it resolves `ctx.attachments` at request time, recursively converts each durable image reference including references nested inside tool results, and emits native image content only for models that declare image input. The shipped composition registers Pi-AI OpenAI and Anthropic routes alongside the text-only default DeepSeek route; selecting the active provider/model remains a host composition or profile concern rather than an image-input CLI feature. Request-time service resolution keeps Cordis load order from freezing optional attachment availability. The hand-written DeepSeek adapter throws typed `UNSUPPORTED_CONTENT` for an image anywhere in the request, including nested tool results. No adapter may flatten or skip an image.

 **Loopback acknowledgement is durable per Harness profile.** The Host half registers a `ui-onboarding` section in the user-settings seam, stored under the active `$DSH_HOME/settings.yaml`. The connection plugin publishes whether the current page uses a loopback authority as `ctx.connection.isLoopback`; hostname classification remains internal to the connection package, and other client plugins consume the service state instead of importing its implementation. A loopback browser shows the notice unless `welcomeNoticeVersion` equals the owner constant exactly. Continue applies one path mutation with the current version and calls `complete()` only after the Host commits it; a failed write leaves the notice open, and closing the page or process writes nothing. Bumping the constant intentionally makes every profile acknowledge the revised copy once. A non-loopback browser must not call the loopback-only settings API. It presents the same notice, but explicit Continue completes the step only in the current browser process; reload or a new process presents it again.
 
-**Concurrent loopback views converge without stale replacement.** The acknowledgement write omits `expectedRevision` deliberately: every loopback tab writes the same version to one path, so the operation is idempotent and preserves sibling fields instead of rebuilding the section. `settings/document-updated` becomes `host/settings-changed`; an already mounted loopback tab refetches and advances when another tab or an external editor commits the current version. The API proxy exposes this one product namespace through a closed allowlist beside configurable-provider namespaces, without treating its changes as model-catalog invalidations.

The API proxy exposes this one product namespace through a closed allowlist beside configurable-provider namespaces, without treating its changes as model-catalog invalidations.
 
 **Onboarding temporarily owns the viewport as one continuous stage.** A solid product surface replaces the complete application view through a body-level portal and marks the underlying app root inert; the exact required mask remains mounted behind that surface with `position:absolute`, zero left/right/bottom offsets, `top:80px`, `rgba(0, 0, 0, 0.24)`, and `backdrop-filter: blur(2px)`. Welcome and conditional credential setup render as successive pages in this stage instead of independent modals. Both pages reuse the Web UI's black `BrandWordmark`. The welcome page preserves the four authored paragraphs verbatim under the `内测声明` title; every paragraph uses one 16/28 body scale, and only the requested action clause inside the final paragraph receives a subtle 500 weight. A short staggered opacity/vertical entrance supplies pacing without blocking interaction and disappears under reduced motion. The title receives initial focus, Continue is the sole button, and no close, Escape, or mask-click path exists.

+# Agent Note: Goal command input projection
+
+Status: implemented
+
+English | [中文](2026-08-01-goal-command-input-projection.zh.md)
+
+## Problem
+
+Human commands execute outside the model turn and persist as `command/run` plus `command/done`. The Web transcript rendered only their result row. On a fresh session, `/goal` therefore cleared the composer and completed successfully while the page stayed on the empty hero; its result became visible only after later conversation content activated Chat. Appending an ordinary `user/message` from the handler would change model-visible history and command semantics.
+
+## Decision
+
+The command registry and durable command lifecycle remain unchanged. `command/run` records the parser-owned name, optional verbatim arguments, source, and invocation id; `command/done` records settlement. Neither event carries browser presentation intent.
+
+The `ui-goal` client plugin registers a Goal-owned Conversation Definition beside the generic command Definition. Both match the same `/goal` `command/run`: the generic Definition retains the durable result row, while the Goal Definition builds a separate `command-input` Chat Node at an earlier fractional anchor. The Goal plugin also registers the keyed React renderer for that Node. Its local component copies only the user bubble's right-aligned geometry and semantic tokens, uses 14px/22px monospace text, and mounts no timestamp, copy, or branch actions.
+
+`Session.composerPhase` treats visible non-command Chat Nodes as conversation content, so `command-input` activates the current conversation while a generic command row alone does not. The Host `summary.blank` bit remains turn-based, so list hiding and blank-session reuse do not change.
+
+The Goal Definition derives `/<name><args.trimEnd()>` from the structured run: separator and internal multiline input survive, while the claimed bare form whose arguments contain one space displays `/goal`. A history window containing only `command/done` has no matching Goal Context, so it keeps the generic result row without inventing an input bubble; loading the older run restores both Nodes.
+
+The model boundary is unchanged. The Goal projection creates no `user/message`, `turn/start`, `step/start`, or `request/header`. Accepted goal mutations reach the model only through the goal domain's existing `<goal_state>` snapshot or clear tombstone, independently of the command-input Node.
+
+## Verification
+
+Goal client tests pin the dual Definition output, ordering, other-command exclusion, bare and multiline text, done-only cuts, renderer semantics, disposal, and fresh-session phase selection. The keyless assembled Web scenario submits bare `/goal` in a fresh session with no model adapter, verifies both rows and the absence of model-surface events, then reloads and verifies the persisted transcript.
+
+## Alternatives considered
+
+**Append `user/message` in the `/goal` handler.** Rejected because the command would become model input and could trigger or alter a later request.
+
+**Add presentation intent to the command registry and durable event.** Rejected because one Goal view would widen the generic command interface and make Session, Chat, and every command fixture carry browser presentation state. The existing `command/run` name and arguments already let the composed Goal client reconstruct its own view.
+
+**Teach the generic command renderer about `/goal`.** Rejected because command-specific view construction belongs to the Goal client plugin. Composing that plugin out must remove the bubble without changing command execution or the generic result row.
+
+**Render every command input as a user bubble.** Rejected because existing control commands deliberately leave a fresh session on the hero; changing them would broaden interaction semantics without a feature-owned Conversation Definition.
+
+## Consequences
+
+One durable `/goal` run feeds two independently owned view Contexts without changing the command capability. Composing `ui-goal` out leaves ordinary command execution and its result row intact. Live tabs and cold reloads agree because both views derive from the same run. A page cut that retains only `command/done` temporarily shows only the result row; if that command is the session's only content, the hero hides the row until an older page restores the run. The session remains list-hidden and reusable until a model turn starts because Host blank semantics remain turn-based.

+# Agent Note: Goal 命令输入投影
+
+Status: implemented
+
+[English](2026-08-01-goal-command-input-projection.md) | 中文
+
+## 问题
+
+面向用户的命令在模型轮次之外执行，并持久化为 `command/run` 与 `command/done`。Web transcript（文本记录）此前只渲染结果行。因此，在新会话中，`/goal` 会清空编辑器并成功完成，但页面仍停留在空白 Hero；只有后续对话内容激活 Chat 后，结果才会显示。若处理器追加普通 `user/message`，将改变模型可见历史与命令语义。
+
+## 决策
+
+命令注册表与持久命令生命周期保持不变。`command/run` 记录由解析器提供的名称、可选的原样参数、来源和调用 id；`command/done` 记录结算。两条事件都不携带浏览器呈现意图。
+
+`ui-goal` 客户端插件会在通用命令 Definition 之外注册一个归 Goal 所有的 Conversation Definition。两者都匹配同一条 `/goal` `command/run`：通用 Definition 保留持久结果行，Goal Definition 则在更早的分数锚点构建独立的 `command-input` Chat Node。Goal 插件还为该 Node 注册 keyed React renderer。它的本地组件只复用用户气泡的右对齐几何形态和语义 token，使用 14px/22px 等宽字体文本，并且不挂载时间戳、复制或分支操作。
+
+`Session.composerPhase` 把可见的非命令 Chat Node 视为对话内容，因此 `command-input` 会激活当前对话，而仅有通用命令行时不会。Host 的 `summary.blank` 位仍以轮次为基础，因此列表隐藏和空白会话复用保持不变。
+
+Goal Definition 根据结构化 run 派生 `/<name><args.trimEnd()>`：分隔符与内部多行输入保持不变；在已认领的裸命令形式中，参数只有一个空格时显示 `/goal`。仅包含 `command/done` 的历史窗口没有匹配的 Goal Context，因此会保留通用结果行，而不会虚构输入气泡；加载包含更早 run 的页面后，两个 Node 都会恢复。
+
+模型边界保持不变。Goal 投影不会创建 `user/message`、`turn/start`、`step/start` 或 `request/header`。已接受的 goal 变更只会通过 goal 领域现有的 `<goal_state>` 快照或 clear tombstone 到达模型，与 `command-input` Node 无关。
+
+## 验证
+
+Goal 客户端测试固定双 Definition 输出、顺序、排除其他命令、裸命令与多行文本、仅含 done 的切分窗口、renderer 语义、资源释放和新会话 phase 选择。无密钥的完整组装 Web 场景在不含模型适配器的新会话中提交裸 `/goal`，验证两行都显示且不存在面向模型的事件，然后重新加载并验证持久化后的 transcript。
+
+## 备选方案
+
+**在 `/goal` 处理器中追加 `user/message`。**不予采纳，因为该命令会变成模型输入，并可能触发或改变后续请求。
+
+**向命令注册表与持久事件添加呈现意图。**不予采纳，因为一个 Goal 视图会扩大通用命令接口，并要求 Session、Chat 和每个命令 fixture（测试前置数据）都携带浏览器呈现状态。现有 `command/run` 的名称和参数已足以让组合后的 Goal 客户端重建自有视图。
+
+**让通用命令 renderer 识别 `/goal`。**不予采纳，因为命令专用视图的构建归 Goal 客户端插件所有。在组合中移除该插件后，气泡必须随之消失，且命令执行和通用结果行不能改变。
+
+**把每条命令输入都渲染为用户气泡。**不予采纳，因为现有控制命令会有意让新会话停留在 Hero；这样修改会在没有功能自有 Conversation Definition 的情况下扩大交互语义。
+
+## 后果
+
+一条持久 `/goal` run 会向两个各自独立归属的视图 Context 提供数据，而不改变命令能力。在组合中移除 `ui-goal` 后，普通命令执行及其结果行保持不变。实时标签页与冷重载会得到一致结果，因为两个视图都派生自同一条 run。页面切分只保留 `command/done` 时，会暂时只显示结果行；如果该命令是会话中的唯一内容，Hero 会隐藏该行，直到加载更早页面恢复 run。由于 Host 的 blank 语义仍以轮次为基础，会话在模型轮次开始前仍从列表中隐藏，并且可以复用。

+# Agent Note: Durable workflow runs in Chat
+
+Status: implemented
+
+English | [中文](2026-08-10-durable-workflow-runs-in-chat.zh.md)
+
+## Problem
+
+The ordinary workflow tool row owns the model call and final tool result, but those two records do not explain which members actually started, how they were grouped, whether each member completed, failed, or was cancelled, or what remained unfinished when a process stopped. Live `workflow/*` events expose those facts only inside the current process, so a refresh or later Session open loses the run history.
+
+The Web Client already assembles business-owned Conversation Nodes from durable Session events. Workflow history therefore needs a producer that can correlate one accepted run with its calling Session, a minimal durable protocol that remains meaningful as a prefix, and an independent renderer that does not take ownership away from the existing tool card.
+
+## Decision
+
+`dsh-tool-workflow` projects every top-level accepted run into the calling Agent's Session. `tool-workflow/run-start` records the stable `runId` and validated name; matching workflow member events record the member sequence, exact label, optional exact phase, child Session id, and outcome; `tool-workflow/run-end` records the stop reason only after the result exists and `run.dispose()` has reached quiescence. Nested transport executions run normally but write no workflow record because they do not own an independent Chat row.
+
+Recording is observational. The first failed Session append disables all later writes for that run, logs one warning, and never changes cancellation, result mapping, or disposal. Each possible failure leaves either no record or a legal continuous prefix: a started run may lack later members or its ending, and a started member may lack its ending. The package invariant rejects duplicate run starts, invalid or reused positive member sequences, unpaired or repeated member endings, a run ending while members remain open, and every update after a run ending on both cold load and live append.
+
+The workflow package exposes browser-safe run and observation vocabulary through `@deepseek-ai/dsh-workflow/types`; live `Agent` requests and control handles remain Host-only. `@deepseek-ai/dsh-tool-workflow/types` owns the four Session events. Client code imports only these type faces, so the Host and Client TypeScript programs share the durable contract without merging Host Cordis context.
+
+`ui-workflow-run` registers one `workflow-run` Conversation Definition and one keyed Chat renderer. Every event independently yields the same `runId`; run-start initializes State, later events update it in log order, and an update-only history tail remains pending until prepend supplies the unique start. The final node keeps the engine-owned key and anchors at run-start, placing it after the original tool call while preserving one React parent from running through terminal state.
+
+The renderer gives each level a distinct visual responsibility. The run uses a 32-pixel module-platform background row with persistent right/down chevrons and an inline state dot plus status text, without a badge. Phases use 32-pixel disclosure rows with title and member count in the flexible main area and a fixed precise aggregate-status tail, without another dot. Members use a 16-pixel dot slot, a truncating name area, and a fixed 64-pixel status column. Phases exist only when a member actually starts and group by the exact phase string; an omitted phase and the empty string retain distinct identities and localized names. Member settlement changes status without removing or reordering the member. A closed Turn or Step turns missing run or member endings into interrupted presentation; a durable ending remains authoritative when present.
+
+Navigation is derived from two current authorities rather than persisted. A member row is interactive only while its durable member state is running and the current ordinary Session list contains the same id with `origin: 'subagent'`, `parentId` equal to the displayed parent, and `running: true`. Underlined member text is the only visible affordance; keyboard focus draws a two-pixel business-primary ring around the name area, and the fixed status label remains the lifecycle word rather than an action instruction. The renderer invokes only the injected ordinary `sessions.open(id)` callback. Addressed-only, remote, wrong-parent, and terminal members remain visible but static.
+
+The [seven-state Figma reference](https://www.figma.com/design/tguwzZRmHCjbq58mfsqT0M?node-id=5-2) fixes the information hierarchy for running expanded/collapsed, completed history/expanded, failed plus cancelled, interrupted recovery, and dark narrow presentation. Repository `DisclosureRow`, `StateDot`, icons, semantic tokens, and keyed-node behavior remain the implementation authority; the reference introduces no runtime field or state owner.
+
+## Verification
+
+Package tests cover top-level and nested eligibility, zero-member and concurrent runs, disposal-before-ending order, all four append-failure prefixes, and cold/live invariant rejection. Conversation tests compare complete replace, update-only prepend, and live append; they cover exact phase identity, terminal and interrupted status, disclosure state, list-fact navigation, and HMR removal and re-registration. The shipped Web replay uses the existing workflow parent and child model fixtures to exercise the real worker, spawn provider, Session persistence, browser bundle, running child navigation, terminal retention, original tool-row coexistence, narrow dark tokens, and refresh reconstruction.
+
+## Alternatives considered
+
+**Append workflow content inside the existing tool card.** Rejected because `ui-tool` and the tool definition own that row's presentation and interaction. A workflow-specific appendix would couple two independently keyed business lifecycles and revive the removed post-tool attachment model.
+
+**Persist a server-side projection or add a workflow wire channel.** Rejected because Session events already provide persistence, live delivery, pagination, and gap repair. Another service, cache, or transport would duplicate the same facts and create a second lifecycle owner.
+
+**Render declared phases or infer a static workflow graph from script text.** Rejected because only member-start events prove work happened. `meta.phases`, `phase()` narration, branches, and script syntax do not describe one authoritative runtime topology.
+
+**Keep terminal child navigation.** Rejected because the workflow record proves historical identity, not current accessibility. Cold or remote Session opening needs a separate catalog and authorization contract; this node grants no such promise.
+
+## Consequences
+
+Workflow progress survives refresh and process recovery in the same log as its parent conversation, while execution ownership remains with the workflow run holder and the original tool card remains unchanged. The durable protocol adds four small events and one package-owned invariant; first-write failure intentionally sacrifices later observation rather than workflow correctness. Browser State is derived per loaded window, disclosure choices remain local, and navigation can disappear as list facts change. The design shows only actual runtime members and statuses, giving up static graph visualization, outputs, logs, controls, and terminal-member opening.

+# Agent Note: Chat 中的持久工作流运行
+
+Status: implemented
+
+[English](2026-08-10-durable-workflow-runs-in-chat.md) | 中文
+
+## 问题
+
+普通工作流工具行拥有模型调用与最终工具结果，但这两条记录无法说明哪些成员真正开始、如何分组、各成员是完成、失败还是取消，也无法说明进程停止时哪些工作尚未结束。实时 `workflow/*` 事件只存在于当前进程，因此刷新或稍后重新打开 Session 会丢失运行历史。
+
+Web Client 已经能够从持久 Session 事件组装由业务拥有的 Conversation Node。工作流历史因此需要：能够把一次已接受运行关联到调用 Session 的生产方、作为前缀也始终有意义的最小持久协议，以及不夺走现有工具卡所有权的独立 renderer。
+
+## 决策
+
+`dsh-tool-workflow` 把每个已接受的顶层运行投影到调用 Agent 的 Session。`tool-workflow/run-start` 记录稳定 `runId` 与已校验名称；匹配的工作流成员事件记录成员序号、精确标签、可选精确阶段、子 Session id 与结果；只有在结果已取得且 `run.dispose()` 完全停稳后，`tool-workflow/run-end` 才记录停止原因。嵌套 transport 执行照常运行，但不会写工作流记录，因为它不拥有独立 Chat 行。
+
+记录只供观察。任一次 Session append 首次失败后，本运行会停止所有后续写入、只记录一次告警，并且绝不改变取消、结果映射或 dispose。每种失败位置都留下空记录或合法连续前缀：已开始运行可以缺少后续成员或运行终点，已开始成员也可以缺少成员终点。包 invariant 会在冷加载与实时 append 时拒绝重复运行 start、无效或复用的正成员序号、无配对或重复成员 end、仍有开放成员时结束运行，以及运行结束后的任何更新。
+
+workflow 包通过 `@deepseek-ai/dsh-workflow/types` 提供浏览器安全的运行与观察词汇；包含活跃 `Agent` 的请求和控制句柄继续只属于 Host。`@deepseek-ai/dsh-tool-workflow/types` 拥有四类 Session 事件。Client 只导入这些类型 face，因此 Host 与 Client TypeScript 程序共享持久合同，而不会合并 Host Cordis Context。
+
+`ui-workflow-run` 注册一个 `workflow-run` Conversation Definition 和一个 keyed Chat renderer。每条事件都能独立给出同一 `runId`；run-start 初始化 State，后续事件按日志顺序更新；只有 update 的历史尾页会保持 pending，直到 prepend 补入唯一 start。最终节点保留引擎拥有的 key，并以 run-start 锚定在原工具调用之后，从运行中到终态始终保留同一个 React 父级。
+
+renderer 为每一层分配不同视觉职责。运行使用 32 像素 module-platform 背景行，常驻向右／向下 chevron，并以内联状态点加状态文字表达结局，不使用胶囊。阶段使用 32 像素 disclosure 行，在可伸缩主区显示标题与成员数，在固定尾部精确显示聚合状态且不重复状态点。成员使用 16 像素状态点槽、可省略名称区和固定 64 像素状态列。阶段只在成员真正开始时出现，并按精确阶段字符串分组；字段缺省与空字符串保留不同身份和本地化名称。成员结算只改变状态，不删除或重排成员。所属 Turn 或 Step 关闭时，缺少运行或成员终点会显示为已中断；存在持久终点时仍以它为权威。
+
+导航从两个当前权威派生，不写入持久记录。只有持久成员状态仍为运行中，且当前普通 Session 列表包含同一 id、`origin: 'subagent'`、`parentId` 等于当前父 Session、`running: true` 时，成员行才可交互。带下划线的成员文字是唯一可见提示；键盘聚焦时，名称区显示 2 像素 business-primary 焦点环，固定状态列继续只表达生命周期，而不写动作说明。renderer 只调用注入的普通 `sessions.open(id)` 回调。仅地址化、远程、父级不符或终态成员继续可见，但保持静态。
+
+[七状态 Figma 参考](https://www.figma.com/design/tguwzZRmHCjbq58mfsqT0M?node-id=5-2)固定运行展开／收起、完成历史／展开、失败与取消、恢复后中断以及暗色窄列的信息层级。仓库的 `DisclosureRow`、`StateDot`、图标、语义 token 和 keyed-node 行为仍是实现权威；参考稿不引入运行时字段或状态 owner。
+
+## 验证
+
+包测试覆盖顶层与嵌套准入、零成员与并发运行、先 dispose 后写终点的顺序、四个 append 失败前缀，以及冷／实时 invariant 拒绝。Conversation 测试比较完整 replace、只有 update 的 prepend 和实时 append，并覆盖精确阶段身份、终态与中断状态、disclosure 状态、列表事实导航、HMR 移除与重新注册。shipped Web replay 复用现有工作流父／子模型 fixture，驱动真实 worker、spawn provider、Session 持久化、浏览器 bundle、运行中子级导航、终态保留、原工具行并存、暗色窄列 token 与刷新重建。
+
+## 曾考虑的替代方案
+
+**把工作流内容附加到现有工具卡。** 拒绝，因为 `ui-tool` 与工具定义拥有该行的展示和交互。工作流专属 appendix 会耦合两个独立 keyed 业务生命周期，并恢复已移除的工具后附加模型。
+
+**持久化服务端 projection 或新增 workflow wire 通道。** 拒绝，因为 Session 事件已经提供持久化、实时传输、分页和 gap repair。另一个 service、cache 或 transport 会复制同一事实并建立第二个生命周期 owner。
+
+**展示声明阶段，或从脚本文本推断静态工作流图。** 拒绝，因为只有成员 start 事件能证明工作真正发生。`meta.phases`、`phase()` 叙述、分支和脚本语法都不是一次运行的权威拓扑。
+
+**保留终态子级导航。** 拒绝，因为工作流记录证明历史身份，不证明当前可访问性。冷 Session 或远程 Session 的打开需要独立目录与授权合同；本节点不作这种承诺。
+

 ## Decision
 
-- **The export is a host-only download, not an RPC**: `GET /api/session.export?sessionId=…&includeDescendants=true` streams one ZIP attachment. Every file is a session's **stored artifact text verbatim**: `readRaw` on the persistence service reads the backend's own durable bytes (the JSONL backend decodes its physical zstd frames, or returns plaintext) — never a reconstruction from parsed events, so packed-chunk rows, key order, and line breaks survive byte-for-byte — under its original base name (`session.jsonl` at the root, `subagents/<id>/session.jsonl` for descendants). Compression runs on the host with fflate's streaming `Zip`/`ZipDeflate` API, each entry deflated in bounded chunks as it is produced, so the response is chunked as it is generated and the host never holds the whole archive in one buffer (at most one descendant's artifact text beyond the preloaded root), and production yields whenever the response queue fills, so a slow consumer bounds the accumulation (fflate's callback is synchronous — the drain point is the only backpressure). No manifest is written — every file is byte-identical to the durable artifact and self-describing through its own header line.
-- **Error vocabulary is HTTP-native**: missing services → 500, missing root session → 404 (both decided before any byte streams), a descendant without a stored artifact → the stream errors (fail-loud, never silent under-export). The carrier (`toFetchHandler`) already applies the `/api` trust fence; the GET branch sits beside the existing SSE GET routes, and `ApiProxy.downloads.sessionLog` (host-only, no wire envelope, absent from `IApiClient`) implements it.
-- **The UI just downloads**: the 导出 button fetches the endpoint and saves the response; the `session.log` RPC that an earlier iteration shipped was removed — the download endpoint is its only consumer, and the repo rule is no public interface without a current owner. The client bundle no longer carries fflate (the earlier browser-entry-alias pitfall is moot).

The archive name is `dsh-session-<sanitized-id>.zip` and archive paths sanitize ids before they can shape entries.

+# Agent Note: Web attachment display aligns with DeepSeek Chat via attachment atoms
+
+Status: implemented
+
+English | [中文](2026-08-11-web-attachment-display-alignment.zh.md)
+
+## Problem
+
+The web composer's image surfaces missed basic usability (user feedback, issue #2248). The remove control hung outside each 72px thumbnail at `top/right: -6px`, so the rail's `overflow-x` box clipped it and clicks aimed at it often missed; previews opened only on double-click, an affordance nothing advertised except a tooltip; a rail wider than the composer produced a raw horizontal scrollbar inside the capsule; and image-intake rejections plus prompt failures (for example `attachment-error` when the selected model takes no image input) rendered as persistent inline red strips above the card. Every one of these surfaces already has a settled design in DeepSeek Chat that users know: single-click preview, an inside-the-card hover-revealed remove control, hidden-scrollbar arrow paging, and a transient top-center toast.
+
+The first multimodal ship recorded these surfaces in the [web multimodal note](2026-07-22-web-multimodal-image-input-and-durable-attachments.md); this note supersedes its display and interaction specifics (thumbnail geometry, click affordance, error presentation) while its attachment seam, admission, and durability decisions stand.
+
+All of this UI also lived inside `dsh-client-ui-conversation` — the rail inline in the 700-line `InputBar`, the history image and lightbox in `chat/` and `skeleton/` — with no seam that another surface could reuse and nothing enforcing the pure-props discipline the pieces already had.
+
+## Decision
+
+Attachment display lives in a new zero-cordis atoms package, `@deepseek-ai/dsh-client-ui-attachment` (`packages/client/ui-attachment`), patterned on `dsh-client-ui-primitives`: `AttachmentRail` (64px/16px-radius thumbnails, single-click `onOpen`, inside-the-card remove control revealed on hover or focus and permanent under `pointer: coarse`, hidden scrollbar with circular edge arrows recomputed from scroll geometry, vertical-wheel horizontal pan clamped to 60px/tick, end-reveal on growth), `MessageImage`/`ImageGallery` (single-click preview), and `ImageLightbox`. Strings arrive as label props; `ui-conversation` bridges its `conversation` dictionary through `src/client/image-labels.ts` and keeps the machine wiring (draft ids, preview state, intake callbacks). The cross-package import is sanctioned exactly because the package is an atoms library, not a client plugin: plugin-to-plugin component imports stay forbidden, and the composer's rail is composer-owned rendering, not a slot.
+
+Both overlays body-portal: the lightbox opened from a chat message sits under transformed ancestors that would trap `position: fixed` in their own box (the backdrop covered only the chat column), so `ImageLightbox` and `Toast` render through `createPortal(document.body)` and cover the viewport from every opener. The transient banner is a `ui-primitives` `Toast` atom (120px from the viewport top, horizontally centered over its optional anchor — the composer card, so it sits over the chat column — `role="alert"`, `pointer-events: none`, three-second hold then one-second fade, `onDone` unmount, keyed per show so identical repeated messages re-announce). `InputBar` routes both intake rejections (`addImages`'s returned reason) and `promptError` through it, replacing the inline strips, and `ModelSelect` routes rejected model selections through the same atom while its in-menu strip with Retry stays the catalog-load surface; the machine-notice strip is untouched. DeepSeek Chat's source (a local reference copy) provided the target behaviors: its `ImageThumbnailInInput` (64px cards, opacity-transition delete), `ScrollArrows` (sentinel-driven paging), and `useToast` usage.
+
+## Alternatives considered
+
+**Keep the components inside `ui-conversation` and only restyle.** Rejected by the user: the attachment surface is expected to grow (file cards, upload progress), and the repo's plugin discipline forbids other plugins importing `ui-conversation` internals, so growth inside the plugin builds an unreusable pile. The atoms package gives the same components a sanctioned import path.
+
+**A `ui-attachment` client plugin registering slots.** Rejected: the rail renders inside the composer the machine owns and the gallery inside chat nodes; neither is a composition hole another plugin should fill, and a plugin would force slot indirection for what are pure presentational components.
+
+**Toast inside `ui-conversation`.** Rejected: nothing about a transient banner is conversation-specific, and `ui-primitives` is the established home for zero-cordis atoms other surfaces may reuse.
+
+**Keep inline error strips and only add the toast for image intake.** Rejected: `promptError` (the `attachment-error` screenshot in the issue) is the surface users actually complained about, and two error presentations in one composer would leave the strip as the odd survivor.
+
+## Consequences
+
+The composer and history image surfaces now match DeepSeek Chat's interaction model, and the label-prop seam means the atoms render under any locale without reaching for one. The cost is a real package boundary: `ui-attachment` carries the standard scaffolding (invariant companion, bilingual README, tsconfig face, per-file 100% coverage) and item strings must be resolved by every future consumer rather than inherited. Error banners are now transient — a user who looks away for four seconds misses the message, the trade DeepSeek Chat itself makes. Non-image attachments remain unsupported; the rail's card model is ready for them but the composer's intake is image-only (tracked in the package README's limitations).

+# Agent Note: Web 附件展示经附件原子组件对齐 DeepSeek Chat
+
+Status: implemented
+
+[English](2026-08-11-web-attachment-display-alignment.md) | 中文
+
+## 问题
+
+Web 输入框的图片界面缺乏基本可用性（用户反馈，issue #2248）。删除按钮以 `top/right: -6px` 挂在 72px 缩略图外侧，被附件栏的 `overflow-x` 盒子裁切，点击经常落空；预览只能双击打开，除了 tooltip 没有任何提示这个操作；附件栏超出输入框宽度时在胶囊内部直接出现原生横向滚动条；图片接收被拒和发送失败（例如所选模型不支持图片输入时的 `attachment-error`）以常驻的内联红条显示在卡片上方。这些界面在 DeepSeek Chat 里都有用户熟悉的既定设计：单击预览、卡片内部悬停显示的删除按钮、隐藏滚动条的箭头翻页、顶部居中的短时 toast。
+
+首个多模态版本把这些界面记录在[Web 多模态 Note](2026-07-22-web-multimodal-image-input-and-durable-attachments.md)中；本 Note 取代其中的展示与交互细节（缩略图几何、点击方式、错误呈现），其附件服务边界、准入与持久化决策继续有效。
+
+这些 UI 还全部住在 `dsh-client-ui-conversation` 里——附件栏内联在 700 行的 `InputBar` 中，历史图片和灯箱分散在 `chat/` 与 `skeleton/`——没有其他界面可复用的接缝，纯 props 的纪律也无从约束。
+
+## 决定
+
+附件展示落位到新的零 cordis 原子组件包 `@deepseek-ai/dsh-client-ui-attachment`（`packages/client/ui-attachment`），模式照 `dsh-client-ui-primitives`：`AttachmentRail`（64px、16px 圆角缩略图，单击 `onOpen`，卡片内部的删除按钮悬停或聚焦显示、`pointer: coarse` 下常显，隐藏滚动条配两端圆形箭头并依滚动几何重算，纵向滚轮转横向平移且单次钳制 60px，新增条目滚到栏尾），`MessageImage`/`ImageGallery`（单击预览），以及 `ImageLightbox`。文案经 label props 传入；`ui-conversation` 通过 `src/client/image-labels.ts` 桥接 `conversation` 词典，并保留状态机接线（草稿 id、预览状态、接收回调）。跨包 import 之所以是被允许的路径，正因为它是原子组件库而非 client 插件：插件之间仍禁止互相 import 组件，且附件栏是输入框自有的渲染，不是插槽。
+
+两个浮层都 portal 到 body：从聊天消息打开的灯箱位于带 transform 的祖先之下，`position: fixed` 会被困在祖先的盒子里（遮罩只盖住聊天列），因此 `ImageLightbox` 与 `Toast` 经 `createPortal(document.body)` 渲染，从任何打开位置都覆盖整个视口。短时横幅是 `ui-primitives` 的 `Toast` 原子（距视口顶部 120px，水平中心跟随可选锚点——composer 卡片，因此横幅在聊天列上居中——`role="alert"`、`pointer-events: none`，停留三秒再一秒淡出，`onDone` 卸载，按展示序号作 key 使相同文案重新播报）。`InputBar` 把接收拒绝（`addImages` 返回的原因）和 `promptError` 都改走 toast，替换内联红条，`ModelSelect` 的模型选择被拒也走同一原子，其菜单内带 Retry 的错误条仍是目录加载的呈现面；状态机 notice 条不受影响。DeepSeek Chat 源码（本地参考副本）提供了目标行为：其 `ImageThumbnailInInput`（64px 卡片、透明度过渡的删除钮）、`ScrollArrows`（哨兵驱动的翻页）与 `useToast` 用法。
+
+## 备选方案
+
+**组件留在 `ui-conversation` 里只改样式。** 被用户否决：附件面预期还会长（文件卡片、上传进度），而仓库的插件纪律禁止其他插件 import `ui-conversation` 内部实现，在插件里生长只会堆出无法复用的一坨。原子组件包给了同样的组件一条被允许的 import 路径。
+
+**做成注册插槽的 `ui-attachment` client 插件。** 否决：附件栏渲染在状态机持有的输入框里，画廊渲染在聊天节点里，二者都不是该由其他插件填充的组合孔位，插件形态会为纯展示组件强加插槽间接层。
+
+**Toast 放在 `ui-conversation`。** 否决：短时横幅没有任何会话特有的东西，`ui-primitives` 是零 cordis 原子组件的既定归属，其他界面也可能复用。
+
+**保留内联红条，只给图片接收加 toast。** 否决：`promptError`（issue 截图里的 `attachment-error`）恰是用户实际抱怨的界面，一个输入框里存在两种错误呈现会让红条成为孤例。
+
+## 结果

 `scripts/project-doc-site.ts` projects the manifest into the ignored `website/.generated/` directory before VitePress starts or builds. The generated tree follows public routes so VitePress navigation, locale detection, and local search share the same route vocabulary.

+Locale home projections retain only the canonical YAML frontmatter. The repository-facing body keeps its H1 and bilingual source links, while the frontmatter implements the [locale-preserving quick-start redirect](../simplification/2026-08-11-quickstart-documentation-home.md) and the site navigation owns locale switching.
 
 The projector parses Markdown links without reserializing the document. A link to another published source becomes a site-relative route; a link to an unpublished repository file becomes a source link under the `deepseek-ai/deepseek-harness` repository home; a repository image is copied into the generated tree and referenced from there ([why](2026-08-06-doc-site-carries-its-images.md)). Missing relative targets fail projection. Unit tests pin these transformations, and `docs:check` runs the projector tests plus a production VitePress build as part of `doc-sync` and the parallel documentation gates.

+# Agent Note: Route documentation roots to quick start
+
+Status: implemented
+
+English | [中文](2026-08-11-quickstart-documentation-home.zh.md)
+
+## Problem
+
+A separate documentation landing page duplicates product positioning and feature summaries owned by the product landing page. Those parallel claims require synchronization and review without helping readers reach technical instructions.
+
+## Decision
+
+Each locale root is a redirect page. `/` sends readers to `./guide/quickstart`, and `/en/` resolves the same relative target to `/en/guide/quickstart`. The relative target preserves the configured `DOCS_BASE` when the site is hosted below an origin path.
+
+`docs/user/index.md` and `docs/user/index.zh.md` own the redirect as VitePress frontmatter. The [documentation-site projector](../process/2026-07-13-documentation-site-projection.md) publishes only that frontmatter for locale homes, so the canonical Markdown retains its bilingual switcher without rendering a second landing page. The projector test verifies that both locale roots use the same locale-relative quick-start target.
+
+Product positioning and feature summaries stay outside the documentation site. Guide, development, reference, search, and locale navigation remain available from the quick-start page.
+
+## Alternatives considered
+
+**Keep a documentation hero and synchronize its wording.** This preserves a promotional entry page but creates a second product narrative whose claims and terminology can drift from the product landing page.
+
+**Render a documentation index at the root.** An index repeats the navigation already provided by the site and inserts another choice before the first actionable guide.
+
+**Copy quick-start content to each locale root.** Two public routes would then own the same tutorial and require another synchronization mechanism.
+
+**Use origin-absolute redirect targets.** Paths such as `/guide/quickstart` ignore `DOCS_BASE` and fail when the documentation site is hosted below an origin path.
+
+## Consequences
+
+Readers entering either locale root immediately reach the quick-start tutorial in that locale. The documentation site gives up a promotional home surface, while the product landing page remains the single owner of positioning and feature summaries. The stable root routes remain valid entry points, and quick-start content retains one canonical source.

+
+## 问题
+
+单独的文档首页会重复产品首页所维护的产品定位和功能摘要。这些重复声明需要同步与评审，却不能帮助读者查阅技术操作说明。
+
+## 决策
+
+每个 locale 根路由都是重定向页面。`/` 将读者导向 `./guide/quickstart`，`/en/` 则把同一相对目标解析为 `/en/guide/quickstart`。当网站托管在源站的子路径下时，相对目标仍会保留配置的 `DOCS_BASE`。
+
+重定向由 `docs/user/index.md` 与 `docs/user/index.zh.md` 的 VitePress frontmatter 维护。对于 locale 首页，[文档网站投影器](../process/2026-07-13-documentation-site-projection.md)只发布这段 frontmatter，因此权威 Markdown 保留中英文语言切换行，且不会渲染第二个首页。投影器测试验证两个 locale 根路由都使用相对于各自 locale 的同一快速开始目标。
+
+文档网站不承载产品定位和功能摘要。快速开始页面仍提供指南、开发、参考、搜索和 locale 导航。
+
+## 考虑过的替代方案
+
+**保留文档 hero 并同步其文案。** 这样会保留一个推广入口页，但也会产生第二套产品叙事，其中的声明和术语可能与产品首页逐渐偏离。
+
+**在根路由渲染文档索引。** 索引会重复网站已有的导航，并在读者开始首篇操作指南之前插入一次额外选择。
+
+**把快速开始内容复制到每个 locale 根路由。** 这样会让两个公开路由同时维护同一篇教程，并需要另一套同步机制。
+
+**使用源站绝对路径作为重定向目标。** `/guide/quickstart` 等路径会忽略 `DOCS_BASE`，当文档网站托管在源站的子路径下时将失效。
+
+## 结果
+
+进入任一 locale 根路由的读者都会立即到达该 locale 的快速开始教程。文档网站放弃推广型首页，产品首页则继续作为产品定位和功能摘要的唯一归属。稳定的根路由仍是有效入口，快速开始内容仍由单一权威来源维护。

+Thank you for your interest in contributing to DeepSeek Harness!
+
+We deeply believe in the power of open source communities, and that belief has shaped this project from the very beginning.
+
+DeepSeek Harness is still at an early stage and under active development. We are sorry that we cannot accept external pull requests at the moment. However, contributing code to this repository is far from the only way to help. There are many other ways to get involved:
+
+- Identify and report issues or bugs in GitHub Discussions.
+  - Upvote discussions that you would like to bring to the team's attention. We are a very small team and may not be able to reply to every post, but we monitor them and consider them when allocating resources.
+- Contribute to the ecosystem:
+  - Create a plugin that excites you and share it with others.
+    - Associate your GitHub project with the `dsh-plugin` topic to help others discover your plugin.
+  - Write blog posts and how-to guides about DeepSeek Harness.
+  - Answer questions and help other members of the community.
+
+DeepSeek Harness is designed to be deeply customizable. We do not believe that packages in the official repository are inherently more important than packages created by the community. You may consider this repository an idea, an official showcase, and a source of inspiration, but not a mandate from us.
+
+We have already seen exciting projects emerge from the community, and we hope to see the ecosystem continue to grow in its own directions.
+
+Into the unknown.

 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 prints the text on stdout and exits 0 for `completed`, else 1. An invocation with no task is a usage error from that app. The shipped headless profile mounts no ApiProxy, Host, HTTP server, Web runtime, or browser client; a successful run writes nothing to stderr and opens no listening port.

+
+These tests boot the real web composition in-process and drive it with a real
+Chromium over real HTTP. The lane's mechanics — modes, fixtures, goldens, and
+the deliberate composition divergences from `dsh web` — are documented in
+[`scaffold.ts`](scaffold.ts) and the
+[browser e2e Agent Note](../../../.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.md).
+
+## These are Host-face tests
+
+They type-check in the root `tsconfig.host.json`, not in the Client aggregate,
+because they read Host services directly: `ctx.apiProxy`, the Host
+`SessionStore`, `ctx.sessionProjectionCache`. Driving a browser at runtime does
+not make a file part of the Client program — the two faces merge cordis
+`Context` under the same keys with different services, so one program cannot see
+both. Moving these files into the Client aggregate makes every Host-service
+access fail to compile.
+
+## Do not import `@deepseek-ai/dsh-client-*` here
+
+Importing a Client package — a value or a type — pulls its whole TypeScript
+project, and every project it references, into the **Host build graph**. That has
+bitten this lane once already: four Client consumer packages reference
+`api/remotes`' Client face, which cannot compile until Host tsdown has generated
+`@deepseek-ai/dsh-goal/remote`, so the Host build phase ended up waiting on an
+artifact it produces itself.
+
+When a scenario needs a Client-owned constant or pure function, mirror it here
+instead, next to the commented-out import that names the source module. A drift
+then surfaces as a missed selector or an unsuppressed notice — a loud failure,
+never a silent pass. `scaffold.ts` holds the mirrored welcome-notice values and
+exports them for the scenarios that assert on them.
+
+Two kinds of Client import stand. `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. Separately,
+the chat scenarios import `conversationContextKey` from
+`@deepseek-ai/dsh-client-runtime/client` because `client/runtime` is reachable
+through the unsplit `directory-picker` packages and pulls nothing further in.
+That reachability is incidental, not a guarantee — if it ever leaves the graph,
+mirror the helper like the rest.
+
+Nothing mechanically enforces this rule; keep it in review.

+这些测试在进程内启动真实的 web 组合，并用真实 Chromium 通过真实 HTTP 驱动它。该 lane
+的运行机制——模式、fixture、golden，以及与 `dsh web` 之间刻意保留的组合差异——记录在
+[`scaffold.ts`](scaffold.ts) 和
+[浏览器 e2e Agent Note](../../../.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.md)中。
+
+## 这些是 Host 面的测试
+
+它们在根 `tsconfig.host.json` 中做类型检查，而不在 Client aggregate 中，因为它们直接读取
+Host 服务：`ctx.apiProxy`、Host 侧 `SessionStore`、`ctx.sessionProjectionCache`。运行时驱动
+浏览器并不使一个文件成为 Client 程序的一部分——两个 face 在相同的键上以不同服务合并 cordis
+`Context`，因此单个程序无法同时看见两者。把这些文件挪进 Client aggregate 会让每一处
+Host 服务访问都无法编译。
+
+## 不要在此 import `@deepseek-ai/dsh-client-*`
+
+import 一个 Client 包——无论值还是类型——都会把它整个 TypeScript 工程、以及它引用的每个工程
+拉进 **Host 构建图**。这已经坑过本 lane 一次：四个 Client 消费方包引用了 `api/remotes` 的
+Client face，而该 face 必须等 Host tsdown 生成 `@deepseek-ai/dsh-goal/remote` 之后才能编译，
+于是 Host 构建阶段变成在等一个由它自己产出的产物。
+
+当某个场景需要 Client 持有的常量或纯函数时，改为在此处镜像一份，并紧挨着一条注释掉的
+import 点明源模块。这样漂移会表现为选择器未命中或提示未被抑制——是响亮的失败，绝不会是静默
+通过。`scaffold.ts` 持有镜像的 welcome-notice 取值，并导出给断言它们的场景使用。
+
+有两类 Client import 是长期成立的。`assembled-boot.ts` 驱动 shell 本身，因此它从
+`@deepseek-ai/dsh-client-web` import `AppWebEntry`、从
+`@deepseek-ai/dsh-client-modules/client` import boot manifest 类型：启动真实 shell 正是该
+harness 的用途，且这两个包本来就在 Host 图中。另外，chat 场景从
+`@deepseek-ai/dsh-client-runtime/client` import `conversationContextKey`，因为
+`client/runtime` 经未拆分的 `directory-picker` 包可达，且不会再牵入别的东西。这种可达性是
+偶然而非保证——一旦它离开该图，就像其余情形那样镜像该 helper。
+
+没有任何机制强制这条规则；靠 review 守住它。

 - A new package is registered in exactly one aggregate. Having both a Node loader entry and a browser entry is not a reason to split a package; an ordinary Client plugin produces both runtime artifacts during the Client build phase.

Its Host entry must participate in the Host TypeRT graph, while its Client entry imports `/remote` declarations that Host tsdown must generate first. The package-root `tsconfig.json` is therefore only a solution, and the two aggregates and direct consumers reference `tsconfig.host.json` or `tsconfig.client.json` respectively. The workspace `constraints` gate walks the reachable Project Reference graph and checks each referencing project's own compiler face: a single-config target remains valid from either face, while a split target must name the matching leaf rather than its solution root or opposite leaf.

 Generated English references and graphs participate in pairing when a reviewed Chinese counterpart is available. Their generators remain the English source of truth, and freshness and pairing gates enforce their respective invariants independently; regeneration that changes English leaves the pair out of sync until the reviewed Chinese counterpart is updated and re-recorded. Generated English sources omit the language switcher that ordinary authored sources carry, because adding it would make the generator stale; their Chinese counterparts still link back to the English source. A generated page's Chinese counterpart may rewrite only self-referential generation and maintenance statements that would otherwise be false for the reviewed translation; all technical content remains subject to the ordinary faithfulness rules.

 有经评审中文对侧的生成英文参考文档和图文档遵循配对规则。生成器仍是英文真源，新鲜度门禁与配对门禁各自独立强制其约束；重新生成导致英文变化后，配对会保持失去同步状态，直至经评审的中文对侧完成更新并重新记录。生成的英文源文件不含普通撰写文档所带的语言切换行，因为添加该行会使生成器新鲜度检查失败；中文对侧仍链接回英文源。生成页的中文对侧只能改写若直译便不再符合经评审译文事实的自指生成与维护说明；所有技术内容仍受普通忠实性规则约束。

 The `workflow/*` events (`workflow/start`, `workflow/phase`, `workflow/log`, `workflow/agent-start`, `workflow/agent-end`, `workflow/end` — see the [events catalog](#cordis-surface)) are **observe-only** emits carrying DATA SNAPSHOTS: every payload starts with `WorkflowRunInfo` (id + meta), never the live `WorkflowRun`, so a subscriber cannot gain `cancel`/`dispose`, and `workflow/end` deliberately omits the result value (a listener observing outcomes must not receive a mutable alias of the caller's result). Every emit is per-listener contained — a throwing subscriber is logged, never propagated, and cannot starve the listeners registered after it — and every listener receives its own payload clone, so mutating it corrupts neither the engine nor other listeners; the containment mirrors `subagent/start`/`subagent/end`.
 
+## Durable Chat records
+
+The top-level `dsh-tool-workflow` consumer projects display facts into its calling parent Session without changing execution ownership. It writes `tool-workflow/run-start` after a run is accepted, pairs member start and end by `runId + seq`, and writes `tool-workflow/run-end` only after the result is known and disposal reaches quiescence. Nested transport calls write no record. The first append failure disables later writes for that run, so the log remains empty or a legal continuous prefix and the tool result is unchanged.
+
+`dsh-tool-workflow/invariant` validates the same protocol before live commit and when a Session is loaded: one start per run, positive unique member sequences, paired member endings, no run ending with open members, and no updates after the run ending. A missing member ending or run ending at the log tail is valid interruption evidence rather than corruption.
+
+`dsh-client-ui-workflow-run` folds the four events through the Conversation Node engine into one `workflow-run` Chat node anchored at the run-start sequence, after the original workflow tool node. Phase groups come only from actual member starts and preserve exact strings, including the distinction between an omitted phase and `''`. Closed Locations turn missing terminal facts into interrupted presentation. The [UI package README](../../packages/client/ui-workflow-run/README.md) owns disclosure, status, and same-parent local navigation behavior.

Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse 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.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse 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.\n\nUse 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.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement an SDK Plugin or installable profile bundle through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:<id>]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` SHORT-CIRCUITS the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n  cordis_mount: {\n    /** JavaScript body returning a temporary Plugin; evaluated now and saved nowhere. */\n    code: string;\n  } & Record<string, JsonValue>;\n  /** Unmount a current-process temporary Plugin created by cordis_mount.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). 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. Script-body hooks: - `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. Resolves `null` when the child fails (filter with `.filter(Boolean)`). 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. - `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. - `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`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: 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.

Sections: `services` (every provided ctx service and the plugin fiber that owns it), `plugins` (all live plugin fibers with their lifecycle states), `tools` (the model-facing tools currently registered, i.e. what you can call), `temporary` (only temporary Plugins created by cordis_mount: id, name, state, provided services, awaited services, and lifetime), `api` (method signatures AND argument/return type shapes for every LIVE service — read this before writing plugin code that calls a service), `events` (every harness event with its dispatch mode and exact signature — pick listener targets here). Temporary Plugins exist only in memory, remain active across later turns, and disappear after cordis_unmount, toolset unload, or DSH restart; they are not restored automatically. The `temporary` section is a subset of `plugins`. Omit `what` to get all six sections. With `what:\"api\"` or `what:\"events\"`, pass an exact `name` to narrow to one service/event and include its original source JSDoc.","parameters":{"type":"object","properties":{"what":{"type":"string","description":"Limit the report to one section. Omit for all sections.","enum":["services","plugins","tools","temporary","api","events"]},"name":{"type":"string","description":"Exact service key or event name whose original JSDoc to include; valid only with what:\"api\" or what:\"events\"."}}}},{"name":"cordis_mount","description":"Mount a temporary Cordis Plugin in the current DSH process. This creates an in-memory runtime Plugin, not an installed or configured Plugin. It remains active across later turns until cordis_unmount, toolset unload, or DSH restart. It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement an SDK Plugin or installable profile bundle through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:<id>]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` SHORT-CIRCUITS the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"JavaScript body returning a temporary Plugin; evaluated now and saved nowhere."}},"required":["code"]}},{"name":"cordis_unmount","description":"Unmount a current-process temporary Plugin created by cordis_mount.

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.

Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order).

It does not create files, install a package, change cordis.yml or personal/project config, survive restart, or automatically become permanent. To keep it, ask the Agent to implement an SDK Plugin or installable profile bundle through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:<id>]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` SHORT-CIRCUITS the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n  cordis_mount: {\n    /** JavaScript body returning a temporary Plugin; evaluated now and saved nowhere. */\n    code: string;\n  } & Record<string, JsonValue>;\n  /** Unmount a current-process temporary Plugin created by cordis_mount.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). 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. Script-body hooks: - `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. Resolves `null` when the child fails (filter with `.filter(Boolean)`). 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. - `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. - `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`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: 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.

Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:<id>]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` SHORT-CIRCUITS the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime.","parameters":{"type":"object","properties":{"code":{"type":"string","description":"JavaScript body returning a temporary Plugin; evaluated now and saved nowhere."}},"required":["code"]}},{"name":"cordis_unmount","description":"Unmount a current-process temporary Plugin created by cordis_mount.

Resolves `null` when the child fails (filter with `.filter(Boolean)`). 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.

Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`.

To keep it, ask the Agent to implement an SDK Plugin or installable profile bundle through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:<id>]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`. Node APIs are DISABLED — do filesystem/network/timer work through the cordis services, never Node built-ins: `require`, `setTimeout`/`setInterval`, and `fetch` throw redirect errors; `process` and `Buffer` are undefined. Instead use inject: ['fs'] + ctx.fs for files, inject: ['web'] + ctx.web for HTTP, inject: ['bash'] + ctx.bash for processes, and inject: ['timer'] + ctx.setTimeout/ctx.setInterval for timing (fiber effects, auto-cleaned when unmounted) — cordis_inspect what:\"api\" shows what THIS runtime provides. Write PLAIN JavaScript, not TypeScript (no `as`, no type annotations). Cautions: (1) waterfall events (e.g. tools/pre-execute) hand the listener a trailing `next` callback which MUST be called — returning without `next()` SHORT-CIRCUITS the call; prefer plain notification events unless you intend to intercept. (2) Never await something that only resolves after the current turn (your code runs INSIDE a tool call of that turn — it would deadlock). (3) Your `ctx` is a restricted façade: you can register tools, observe events, provide/consume services, and use timers, but framework internals (ctx.root, ctx.fiber, ctx.extend, ctx.plugin, …) are withheld. It is not a security boundary though — the services you inject (e.g. ctx.bash) reach the real runtime. */\n  cordis_mount: {\n    /** JavaScript body returning a temporary Plugin; evaluated now and saved nowhere. */\n    code: string;\n  } & Record<string, JsonValue>;\n  /** Unmount a current-process temporary Plugin created by cordis_mount.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). 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. Script-body hooks: - `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. Resolves `null` when the child fails (filter with `.filter(Boolean)`). 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. - `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. - `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`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: 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.

To keep it, ask the Agent to implement an SDK Plugin or installable profile bundle through the regular development workflow. It may affect other sessions in the same process; the sandbox is not a security boundary, and injected services reach the real runtime. `code` runs now as the body of an async JavaScript function in an isolated sandbox and MUST `return` a plugin. Two forms: FUNCTION form `return (ctx) => { … }` — declares no inject, so it can register tools, listen to events, and provide services, but reaching ANY service (e.g. ctx.bash) throws; use it only when you need no services. OBJECT form `return { name?, inject: ['bash', 'llm', …], apply(ctx) { … } }` — declares dependencies, and cordis activates the plugin only after the services exist; PREFER this form. You may reach ONLY the services you list in inject: an undeclared service throws even if it exists, because an undeclared dependency would not be cleaned up if its provider is unmounted. BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks. Temporary Plugins can COMPOSE: one Plugin may `ctx.provide('name', value)` a service and another may declare `inject: ['name']` to consume it — the consumer stays pending until the provider exists and returns to pending when the provider is unmounted. Everything registered inside `apply` is cleaned up automatically by cordis_unmount. Sandbox globals: `console` (tagged `[cordis:<id>]`, writes through to the harness terminal), `harness.defineTool`, `harness.registerTool`, `btoa`, `atob`, `TextEncoder`, `TextDecoder`.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). 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. Resolves `null` when the child fails (filter with `.filter(Boolean)`). 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.

 Each call validates positional inputs, constructs the descriptor's exact named `args`, and sends it through `ctx.connection.rpc.call('/api', endpoint, ...)`. Generated cancellation-aware methods accept a final optional `AbortSignal`; the Client combines it with the contribution mount lifetime before calling Connection. The returned value is validated before reaching application code. Withdrawing a contribution removes its descriptors and methods together, aborts in-flight calls, and makes retained method handles reject.
 
+`ctx.remote.$on()` subscribes to one forwarded Host event. Its legal keys are exactly the Host assembly's forwarding selection, and the listener type is the owning package's own Cordis `Events` declaration, so no second signature can drift from it. Each subscription belongs to the calling fiber and disappears with it. Delivery is one-way and follows registration order; a listener that throws is logged and isolated from the remaining listeners, which never affects the frame pump. `ctx.remote.$dispatch()` is the other half of that surface, and it is the carrier's: the Client half owning the Host frame sink hands each decoded frame over, and an event name nobody subscribes to is dropped, since the wire carries whatever the Host selected. A consumer subscribes and never calls it.
+
 Generated declaration merges provide the TypeScript API through the shared `TypeRTClientRemote` contract. The Client entry contains no Host Service or Host Cordis interface merge, and method lookup and invocation use ordinary objects and functions rather than a JavaScript Proxy.

+The current Client assembly mounts only the Goal Remote contribution. Cordis effect ownership withdraws every contribution when this assembly unloads, while `@deepseek-ai/dsh-api-gateway/client` owns descriptor validation, traced namespace Services, direct and scoped methods, invocation, and cancellation. The Client entry consumes the shared `TypeRTClientRemote` interface through Cordis and does not import the concrete Gateway. It re-exports the Gateway Client face's declaration merges type-only, so a consumer reaching the forwarded-event vocabulary through this facade gains no runtime edge to the Gateway implementation.
 
 This package contains no transport or Host service discovery logic. Its Client face can be reused by Web or a future TUI that provides the same React-free `ctx.remote` contract.
 
+## Forwarded Host events
+
+`src/remote-events.ts` holds `API_REMOTE_FORWARDED_EVENTS`, the allowlist of Host cordis events this application forwards to consumers verbatim — no projection, no redaction, no renaming — and therefore the legal key set of `ctx.remote.$on`; the type-only `src/types.ts` derives its selection face. Forwarding one more event is an entry in that array and nothing else: the type projection, the consumer key face, and the Host forwarding loop all derive from it.
+
+The listener signature is not restated here. Each allowlisted event's cordis `Events` declaration lives in its owner package's client-safe `./types` export (`dsh-agent-presets`, `dsh-commands`, `dsh-credentials`, `dsh-llm`, `dsh-settings`), and both faces of this package pull those declarations in, so "forwarded verbatim" holds by construction rather than by proof. The Host face additionally asserts the list against `TypeRTForwardableEvent`, which rejects a name that is not a declared event, one that binds an AgentScope, and one whose shape is not one-way.
+
 ## Build boundary
 
 An ordinary repository package belongs to one TypeScript face: Host packages are registered in the root `tsconfig.host.json`, and Client packages in the root `tsconfig.client.json`. `api-remotes` is the only deliberate exception because its Host entry must participate in the Host TypeRT graph, while `src/client/index.ts` cannot compile until Host tsdown has generated the business packages' `/remote` declarations.
 
-This package's root `tsconfig.json` is only a solution that references `tsconfig.host.json` and `tsconfig.client.json`. The Host aggregate and direct Host consumers reference the former, while the Client aggregate and direct Client consumers reference the latter; the package-root solution must not enter either aggregate's dependency graph. The two projects own disjoint source files and `.tsbuildinfo` files but share the `lib/types` output directory.
+This package's root `tsconfig.json` is only a solution that references `tsconfig.host.json` and `tsconfig.client.json`. The Host aggregate and direct Host consumers reference the former, while the Client aggregate and direct Client consumers reference the latter; the package-root solution must not enter either aggregate's dependency graph. The two projects own disjoint source files and `.tsbuildinfo` files but share the `lib/types` output directory, with one deliberate exception: `src/remote-events.ts` and `src/types.ts` are listed in BOTH faces' `files`, because the forwarded-event allowlist is the single control point over what a consumer can receive, and the Host forwarding loop and the Client `ctx.remote.$on` key face must read one declaration rather than two that could drift.
+
+That exception is not just a `files` entry. The root `tsconfig.base.json` maps `@deepseek-ai/dsh-api-remotes/types` to `src/types.ts` — the source plane, like every other workspace subpath and unlike the generated `/remote` artifacts, which have no `paths` entry and resolve through `exports` to built output. Both faces therefore admit the same allowlist and type projection into their own programs and emit byte-identical `remote-events` and `types` outputs into `lib/types`; the `.tsbuildinfo` files stay independent. No gate enforces the faces' source-file disjointness — `scripts/project-reference-faces.ts` only checks that a reference into a split project names the matching face — so this paragraph records why the double listing is intentional.
 
 The package-local `clientBundle(..., { hostPhase: true })` makes Host tsdown bundle the Host entry and the later Client tsdown bundle only the browser entry. Ordinary Client plugins remain single Client projects and produce both their Node loader entry and browser bundle during Client tsdown; do not copy this package's split merely because a package has both `src/index.ts` and `src/client/index.ts`.

+
 
 本包不包含传输逻辑或 Host 服务发现逻辑。Web 或未来的 TUI 只要提供同一份不依赖 React 的 `ctx.remote` 约定，均可复用其 Client face。
 
+## 转发的 Host 事件
+
+`src/remote-events.ts` 持有 `API_REMOTE_FORWARDED_EVENTS`——本应用原样转发给消费端的 Host cordis 事件名单（无投影、无脱敏、无改名），它同时就是 `ctx.remote.$on` 的合法键集；只含类型的 `src/types.ts` 派生其选择面。多转发一个事件只需在该数组里加一行：类型投影、消费端键面与 Host 转发循环全部由它派生。
+
+监听器签名不在此处重写。名单内每条事件的 cordis `Events` 声明都住在其 owner 包 client-safe 的 `./types` 出口（`dsh-agent-presets`、`dsh-commands`、`dsh-credentials`、`dsh-llm`、`dsh-settings`），本包两个 face 都把那些声明纳入编译面，因此「原样转发」是构造性成立的，不需要另立证明。Host face 还额外把名单断言给 `TypeRTForwardableEvent`：未声明的事件名、绑定 AgentScope 的事件、以及形状不是单向的事件都会在此被拒绝。
+
 ## 构建边界
 
 仓库中的普通包只属于一个 TypeScript face：Host 包登记在根 `tsconfig.host.json`，Client 包登记在根 `tsconfig.client.json`。`api-remotes` 是唯一刻意拆分的特例，因为它的 Host 入口要参与 Host TypeRT 图，而 `src/client/index.ts` 必须等 Host tsdown 生成业务包的 `/remote` 声明后才能编译。
 
-本包根 `tsconfig.json` 只是引用 `tsconfig.host.json` 与 `tsconfig.client.json` 的 solution。Host aggregate 和 Host 直接消费方引用前者，Client aggregate 和 Client 直接消费方引用后者；禁止把包根 solution 放进任一 aggregate 的依赖图。两个 project 拥有互不重叠的源码和 `.tsbuildinfo`，但共享 `lib/types` 输出目录。
+本包根 `tsconfig.json` 只是引用 `tsconfig.host.json` 与 `tsconfig.client.json` 的 solution。Host aggregate 和 Host 直接消费方引用前者，Client aggregate 和 Client 直接消费方引用后者；禁止把包根 solution 放进任一 aggregate 的依赖图。两个 project 拥有互不重叠的源码和 `.tsbuildinfo`，但共享 `lib/types` 输出目录——只有一处刻意的例外：`src/remote-events.ts` 与 `src/types.ts` **同时**列进两个 face 的 `files`，因为转发事件名单是「消费端能收到什么」的唯一控制点，Host 转发循环与 Client 的 `ctx.remote.$on` 键面必须读同一份声明，而不是两份可能彼此漂移的声明。
+
+这条例外不止是一行 `files`。根 `tsconfig.base.json` 把 `@deepseek-ai/dsh-api-remotes/types` 映射到 `src/types.ts`——**源平面**，与其余所有 workspace 子路径一致，也与生成的 `/remote` 产物相反（后者没有 `paths` 条目，靠 `exports` 命中构建产物）。于是两个 face 都把同一份名单与类型投影收进各自的 program，并向 `lib/types` 发射逐字相同的 `remote-events` 与 `types` 输出；`.tsbuildinfo` 仍各自独立。没有任何门禁强制两个 face 的源文件互不重叠——`scripts/project-reference-faces.ts` 只校验「引用一个 split project 必须指到对应 face」——因此本段记录这次双列为何是有意的。
+
 
 包内 `clientBundle(..., { hostPhase: true })` 让 Host tsdown 打包 Host 入口，让后续 Client tsdown 只打包 browser 入口。普通 Client 插件仍使用单一 Client project，并在 Client tsdown 阶段一起生成 Node loader 入口和 browser bundle；不得因一个包同时存在 `src/index.ts` 与 `src/client/index.ts` 就复制本包的拆分。

 The private local implementation of [`@deepseek-ai/dsh-attachment`](../attachment). Objects land at `<DSH_HOME>/attachments/v1/objects/<sha256-prefix>/<sha256>` and are addressed by an opaque `sha256:` id. Each process proves a home durable once by syncing every ancestor entry to the filesystem root, so a directory another process created but has not yet synced is never mistaken for a safe boundary. Writes then use a private staging directory, owner-only files, a synced temporary file, an atomic exclusive hard-link publish, and directory syncs on the publication path (POSIX; Windows relies on filesystem metadata journaling) so the reported reference survives a crash. Write admission and reads fully decode the raster before accepting its format and dimensions; reads also re-check the digest and logged metadata. Byte and pixel limits are write-time admission policy, so a later policy reduction does not make already-admitted history unreadable.

 The durable attachment seam. `ctx.attachments` validates and atomically commits immutable image bytes, then returns a serializable `ImageAttachmentRef`; consumers never persist browser paths, object URLs, provider URLs, or base64 in session events.

 Loader defers a row's `!!js` interpolation until that row's declared injections are active, then evaluates against the row's plugin context. The example above can therefore read `ctx.webStartup` directly: Cordis has already populated that injected service before Loader asks for `webserver`'s config. Include trees preserve nested expression nodes until each target row reaches this point. Provider replacement and live patch reload repeat interpolation against the current injected services, so a launch flag cannot be silently reset.
 
-`enableRow(ctx, id)` turns on a row a bundle ships disabled because only some invocations want it (`dsh web --dev` and its client-plugin reload chain). The activation is an in-memory override: it does not rewrite the row's configured `disabled` value and survives config reapplication for that mounted entry. Loader applies the enabled row's ordinary injection ordering.

 ### Shared immutable arguments
 
 `get()` does not consume or mutate argv. Multiple plugins can parse the same snapshot and independently provide services. The launcher does not inspect the composition for a command-line owner; a profile with no reader simply ignores its app arguments.

-Hot reload for script-loaded client plugins. A static-arrival entry composed only into `--dev` graphs (`dsh web --dev`); production graphs omit the row, so the shell-bundled code stays inert.
+Hot reload for script-loaded client plugins. The web bundle mounts the row unconditionally; without a rebuild watcher (`pnpm run dev:web`) rewriting client bundles, the poll observes no changes and the chain stays idle.
 
 The browser half subscribes to the system SSE channel (`GET /plugins/events`) and reloads one plugin per `rebuilt` frame through a serialized queue. The sequence per frame — `invalidate`, `prefetch` (load and register the new bundle while the old fiber still serves), `registry.delete` (before the fiber: a bare fiber dispose trips the vendored Loader's self-dispose branch, which would mark the entry disabled), drain the old fiber, delete `entry.fiber`, remove owned `<style data-plugin>` tags, `entry.refresh()` re-imports and remounts, `fiber.await()` rethrows startup failures loud. Dependents reload through cordis itself: a fiber's activation epoch strings its service providers' uids, so replacing a provider's fiber cascades every dependent with zero client-side graph analysis. The node half detects rebuilds with one interval that stat-polls each graph bundle from a synchronous baseline, immediately re-hashes after adding a row, retains missing rows as dirty, and broadcasts only real rev changes; any tsdown watch process producing the bundle therefore triggers HMR with no builder→host channel.

-为通过脚本加载的客户端插件提供热重载。该静态加载配置项只组合进 `--dev` 图（`dsh web --dev`）；生产图省略该项，因此打包进 shell 的代码保持不活动。
+为通过脚本加载的客户端插件提供热重载。web 组合包无条件挂载该行；没有重建 watcher（`pnpm run dev:web`）改写客户端 bundle 时，轮询观察不到变化，链路保持空闲。
 
 浏览器侧订阅系统 SSE（Server-Sent Events）通道（`GET /plugins/events`），每个 `rebuilt` 帧重载一个插件，并通过队列串行执行。每帧的顺序是：`invalidate`、`prefetch`（旧 fiber 仍在服务时加载并注册新组合包）、`registry.delete`（在 fiber dispose（资源释放）之前执行：仅 dispose fiber 会触发 vendored Loader 的 self-dispose 分支，把配置项标为禁用）、排空旧 fiber、删除 `entry.fiber`、移除自身拥有的 `<style data-plugin>` 标签、通过 `entry.refresh()` 重新导入并挂载、通过 `fiber.await()` 直接重新抛出启动失败。依赖方由 Cordis 自身重载：fiber 的激活 epoch 会串联其服务提供方的 uid，因此替换提供方 fiber 会级联所有依赖方，无需客户端图分析。node 侧使用一个 interval 检测重建：从同步基线开始 stat-poll 每个图组合包；新增一行后立即重新计算 hash；缺失行保持 dirty；只广播真实 rev 变更。因此，任何生成组合包的 tsdown watch 进程都能触发 HMR（热模块替换），无需 builder→host 通道。

-Client cordis boot and React-free object services: SlotsService wraps SlotCore and supplies renderer data sources; SessionsService owns Session objects, list and scope state, and the shared event window and history paging used by registered conversation view targets. WorkspacesService depends on SessionsService and owns Workspace objects, list/actions, default-target derivation, and the New Session blank-reuse entry (`connectWorkspace`). The runtime fans the shared Host stream into Session and Workspace owners and bridges the registry-invalidation frames to typed ctx events (`commands/changed`, `session/preset-changed`, `settings/changed`, `credentials/changed`, `models/changed`) so surface caches refetch without touching the stream. `host/session-preset-changed` also folds its preset into the session row, because the switch's RPC echo reaches only the client that issued it. Client sessions are always Host-born (Session+Agent+cwd in one `session.create`); the client holds no pre-entity session state — a session's Agent scope (the client mirror of host dsh-scope, keyed by the shared agent/session id) is born when its row enters the list mirror and dies with the prune. Contract: api-contracts v3 §4. Each `Session` holds a generic `ProjectionValueStore` seeded from the history-tail `projections` block and updated by `session/projection` frames under higher-seq-wins; domain keys (including `todos`) are read via `projections.faceOf` / `useProjection`, not via `ConversationSnapshot`. The store also publishes one reference-stable whole-value map through `SessionSummary.projectionValues`, allowing global list consumers to reuse the same projections without creating per-session subscriptions.

WorkspacesService depends on SessionsService and owns Workspace objects, list/actions, default-target derivation, and the New Session blank-reuse entry (`connectWorkspace`).

 `bindSettingsScope` is the browser mirror of the Host-side settings owner seam for one domain-owned namespace. It subscribes before starting a nonblocking initial read, publishes a uSES snapshot (status, section value, revision, writability, host/memory mode), serializes `set` writes with the latest known namespace revision, suppresses stale publications, recovers a rejected latest write from Host state, and reaches quiescence on plugin disposal. The default decoder validates each section against the namespace's own serialized wire schema (rehydrated through dsh-client-schema-form), so a domain adds a decoder only to narrow beyond that schema. Loopback pages use the Host settings API; remote pages stay in memory mode. Domain packages own the namespace schema, default, and live service rather than putting product policy in runtime.

 `WorkspacesService.connectWorkspace(workspaceId)` resolves the session a New Session flow lands in: it reuses the workspace's existing blank session from the list mirror (`blank && cwd == workspace.path && sessionIds.includes(id)` — the host's own membership rule, never cwd alone, so a cwd-matching unaccounted blank session is never hijacked) or calls `session.create({workspaceId})`, returning the session id for the caller to open. `SessionSummary.blank` mirrors the host's derived empty-log bit and only ever lowers on the client: seeded by `session.list` / the `host/session-added` frame, flipped false by the first ACCEPTED local `prompt()` (on the RPC success response — acceptance proves the user message is in the host log; a rejected first prompt keeps the session blank and reusable) and by any `running: true` status frame, re-aligned by every list re-pull. List surfaces hide blank rows; the store carries every row. `SessionsService.create` accepts an optional caller-preallocated SessionId and throws `SessionCreateError` (carrying `requestedSessionId`) on failure.
 
+`Session.composerPhase` treats any visible non-command Chat Node as conversation content, so a client plugin can project durable human input without opening a turn while a window containing only generic command rows retains the Host blank posture. List hiding and blank-session reuse still follow the Host blank bit. A history window that lacks the plugin-owned input Node returns to that blank posture until an older page restores it.

 ## Pending queue projection
 
 `ConversationSnapshot.queue` is the Host's authoritative transient snapshot of `agent.inbox.nextTurn`; pending next-step steering stays outside this projection. Each row carries its `MessageId`, complete editable text when every content block is text, and a flattened preview. The Host derives whole `session/queue` snapshots from durable `agent/inbox/spliced` mutations and sends a baseline on reconnect; the message-local `agent/inbox/inserted`, `claimed`, and `discarded` notifications are not used to reconstruct this projection. `Session.updateQueue()` sends edit/remove operations through Host-side `Inbox.splice()` without optimistic client mutation, so the next Host snapshot is the sole visible commit and a claim race can surface `queue-item-not-found`.

+# @deepseek-ai/dsh-client-ui-attachment
+
+English | [中文](README.zh.md)
+
+Pure React attachment atoms (zero cordis): the composer draft-image rail (`AttachmentRail`), the chat-history image gallery (`MessageImage`/`ImageGallery`), and the original-image lightbox (`ImageLightbox`). Every string arrives through label props resolved by the owning plugin's own locale namespace, and nothing here reads application state; `@deepseek-ai/dsh-client-ui-conversation` is the current consumer, bridging its `conversation` dictionary through its `image-labels` module.
+
+## Attachment rail
+
+`AttachmentRail` renders pending draft images as fixed 64px thumbnails (16px radius) in one horizontally scrolling row whose scrollbar stays hidden. Overflow is announced by circular edge arrows instead: each pages one viewport (minus one card of context, floored at 200px) with smooth scrolling (instant under `prefers-reduced-motion: reduce`), and arrow visibility is recomputed from scroll geometry on scroll, item-count changes, and rail size changes (a ResizeObserver on the rail element, so sidebar and panel resizes count, not only window resizes). The rail scrolls horizontally only: a non-passive listener consumes every wheel tick with a vertical component — nothing scrolls the conversation behind the composer — converting a pure vertical wheel to a horizontal step (LINE/PAGE deltas normalized to pixels, per-tick travel clamped to 60px) and keeping a diagonal pan's horizontal intent, while purely horizontal pans stay native. A newly added item is revealed at the rail's end; removal keeps the scroll position, and a rail that mounts over an already-populated draft keeps its start position. Each thumbnail opens its original through `onOpen` on a single click, and its remove control sits inside the card's top-right corner, hidden until the card is hovered or the control keyboard-focused; coarse-pointer (touch) surfaces show it permanently because they have no hover. The owner decides mounting and renders the rail only while items exist.
+
+## Message images and the lightbox
+
+`MessageImage` renders one durable history image bounded to 240px on its longer edge, loading a session-authorized URL through the owner's `ImageLoader`; a failed load renders an explicit retry control, and a settled load answers a single click by opening `ImageLightbox` (clicks during loading are ignored). `ImageGallery` wraps a message's images in one aligned flex group (`end` for user messages, `start` for assistant messages) and renders nothing for an empty list. `ImageLightbox` is a document-level modal preview that closes on Escape, a backdrop press, or its close control, and restores focus to its opener on unmount.
+
+## Model Experience
+
+None, as the package renders pure React atoms in the browser; nothing here reaches a model request.
+
+#### KV Cache effect
+
+None; this package neither assembles nor sends a provider request.
+
+## Known Limitations and Deferred Work
+
+- **Images only** — non-image files have no rail card or history renderer yet; DeepSeek Chat-style file cards and upload-progress states wait until the composer accepts non-image attachments.
+- **No zoom or download in the lightbox** — the preview renders the original at fit-to-viewport size only.
+- **The lightbox does not trap focus** — it sets `aria-modal` and restores focus on close, but Tab can reach the page behind it (behavior carried over from the pre-package component).

+
+纯 React 附件原子组件（零 cordis）：输入框草稿图片栏（`AttachmentRail`）、聊天历史图片画廊（`MessageImage`/`ImageGallery`）与原图灯箱（`ImageLightbox`）。所有文案都由持有方插件在自己的语言命名空间中解析后经 label props 传入，此包不读取任何应用状态；当前消费者是 `@deepseek-ai/dsh-client-ui-conversation`，经其 `image-labels` 模块桥接 `conversation` 词典。
+
+## 附件栏
+
+`AttachmentRail` 将待发送草稿图片渲染为固定 64px（16px 圆角）的缩略图横排，滚动条始终隐藏，溢出改由两端的圆形箭头提示：每次翻页滚动一个视口宽度（减去一张卡片作为上下文，下限 200px）并平滑滚动（`prefers-reduced-motion: reduce` 下瞬时完成），箭头的显隐在滚动、条目数量变化和栏自身尺寸变化时依据滚动几何重算（rail 元素上的 ResizeObserver，因此侧栏、面板的宽度变化也计入，不只是窗口尺寸变化）。附件栏只允许横向滚动：非 passive 监听器消费所有带纵向分量的滚轮事件——不会滚动输入框背后的会话记录——纯纵向滚轮转为横向步进（LINE/PAGE 单位先归一化为像素，单次行程钳制在 60px 内），对角平移保留其横向分量，纯横向平移保持原生滚动。新增条目会滚动到栏尾展示，删除则保持原位，带着已有草稿重新挂载的栏保持起始位置。每张缩略图单击经 `onOpen` 打开原图，删除按钮位于卡片内部右上角，悬停卡片或键盘聚焦时才显示；粗指针（触屏）设备没有悬停，因此常显。是否挂载由持有方决定，仅在有条目时渲染。
+
+## 消息图片与灯箱
+
+`MessageImage` 渲染一张持久化历史图片，长边收敛到 240px，经持有方的 `ImageLoader` 加载会话授权 URL；加载失败渲染显式重试按钮，加载完成后单击打开 `ImageLightbox`（加载中的点击被忽略）。`ImageGallery` 将一条消息的图片包为一个对齐的弹性分组（用户消息 `end`，助手消息 `start`），空列表不渲染。`ImageLightbox` 是文档级模态预览，按 Escape、按下遮罩或点关闭按钮均可关闭，卸载时将焦点还给打开者。
+
+## 模型体验
+
+无。该包（package）在浏览器中渲染纯 React 原子组件；这里没有任何内容进入模型请求。
+
+#### KV Cache 影响
+
+无；该包既不组装也不发送提供方请求。
+
+## 已知限制与暂缓事项
+
+- **仅支持图片** — 非图片文件尚无附件栏卡片与历史渲染；DeepSeek Chat 风格的文件卡片和上传进度状态等输入框接受非图片附件后再做。
+- **灯箱无缩放与下载** — 预览仅以适配视口的尺寸渲染原图。
+- **灯箱不锁定焦点** — 它设置 `aria-modal` 并在关闭时归还焦点，但 Tab 仍可移动到背后的页面（沿袭入包前组件的行为）。

 `src/client/contract.ts` is the fixed business contract: `CommandServiceContract.register(name, spec)` and `decorate(name, spec)` are everything a business package consumes; `CommandUiSpec{options, onSelect}` keeps popup data self-contained — the shell component belongs to this package and business packages never see it. A contribution is a client-owned command (a host-name collision fails loud); a decoration adds a bare-invocation popup to an EXISTING host command. The host keeps its catalog row, argument claim (space / argued Enter), and lifecycle logging, and a decorated name with no host row in the session's directory never fires. Command kinds derive per dispatch, never per registration: a host descriptor with `input` is `leadingInput`, a registered `CommandUiSpec` is `popupSelect`, and everything else is `execute`.
 
-`CommandDirectory` (`src/client/directory.ts`) is the one wire-derived cache, keyed by session. Ordinary sessions fetch through `command.list({sessionId})`, and the source's scope-birth `warm` hook prewarms the session's entry. Catalog-addressed continuable children resolve an empty command directory locally: `command.list` is Agent-bound, so prewarming it would activate a child merely to view persisted history. Entries are soft-invalidated by the `commands/changed` typed event (old snapshot serves while the repull flies) and by `session/preset-changed` for that one session (recomposing an agent registers nothing, so the registry-wide signal never fires for it), hard-invalidated by `connection/reset`, epoch-guarded so a superseded pull can never overwrite a newer one. `matchSpace` answers synchronously from this cache only; `matchEnter` strong-waits it on the SubmitAttempt signal and rejects on warmup failure — a `/` line is never silently downgraded to a plain prompt.

 Menu queries fuzzy-match ordered, case-insensitive subsequences of command names. Prefixes rank first; separator boundaries, adjacent characters, and shorter gaps rank the remaining matches, with directory and contribution order breaking ties. This affects discovery only: space and Enter still require an exact command name. Rationale: [Web slash-command fuzzy discovery](../../../.agents/notes/implemented/feature/2026-08-04-web-slash-command-fuzzy-discovery.md).

 `src/client/contract.ts` 是固定的业务 API 约定：`CommandServiceContract.register(name, spec)` 与 `decorate(name, spec)` 是业务包消费的全部内容；`CommandUiSpec{options, onSelect}` 自己提供 popup 数据——外层组件归本包所有，业务包永远见不到它。contribution 是 client 自有命令（与 host 同名碰撞即 fail-loud）；decoration（装饰）则为**已存在的** host 命令添加裸调用 popup。host 保留目录行、带参 claim（space / 带参 Enter）与生命周期记账，被装饰的名字若在会话目录中无 host 行，则永不触发。命令类型按每次派发派生，绝不在注册时定型：带 `input` 的 host descriptor 是 `leadingInput`，注册了 `CommandUiSpec` 的是 `popupSelect`，其余全部是 `execute`。
 
-`CommandDirectory`（`src/client/directory.ts`）是唯一的 wire 派生缓存，以会话为 key。普通会话通过 `command.list({sessionId})` 拉取，source 的 scope 出生 `warm` 钩子会预热该会话的缓存项。由目录寻址的可继续子代理会在客户端解析为空命令目录：`command.list` 绑定 Agent，若预热它，就会仅因查看持久化历史而激活子代理。缓存项由 `commands/changed` 类型化事件软失效（重拉在途期间旧快照继续服务），也由 `session/preset-changed` 对该会话单独软失效（重组 agent 不产生任何注册，注册表级信号不会为它触发），由 `connection/reset` 硬失效，并以 epoch 把关，被取代的旧拉取永远无法覆盖更新的结果。`matchSpace` 只凭该缓存同步应答；`matchEnter` 在 SubmitAttempt 信号上强等缓存，预热失败即拒绝——`/` 开头的一行绝不会被静默降级为普通提示词。

 菜单查询会按顺序且不区分大小写地模糊匹配命令名的子序列。前缀排名最高；其余匹配项按分隔符边界优先、相邻字符优先、间隔越短越优先的规则排序，若仍同分，则以目录顺序和 contribution 顺序打破平局。此行为只影响命令发现：space 和 Enter 仍要求命令名精确匹配。原理：[Web 斜杠命令模糊发现](../../../.agents/notes/implemented/feature/2026-08-04-web-slash-command-fuzzy-discovery.md)。

 Goal surface plugin, browser half: the `GoalBar` strip is the second standalone card in the `conversation.input.dock` composer-context stack (order 10, after Todo and before Queue). The live goal arrives through `useProjection('goal')` — the host-computed whole value seeded by the history tail page and updated by `session/projection` frames — so the plugin owns no domain store, refresh chain, or event listener. The slot inject face carries only the four mutation verbs (edit / pause / resume / clear through `ctx.remote.goals` — an active goal offers the pause action, a paused one resume); each reads the CAS ref from the session's current projected value at call time and surfaces the rejected Remote error inline. The strip single-flights mutations synchronously because React's pending render cannot fence same-frame clicks; after a successful clear it immediately suppresses that exact goal id while the authoritative null projection catches up. Goal creation stays on the `/goal` host command; loading, absent, completed, and successfully cleared goals render nothing.
 
+The plugin separately projects each durable `/goal` `command/run` through its own Conversation Definition. It builds a `command-input` Chat Node before the generic command result Node and registers that Node's keyed renderer as a right-aligned 14px/22px monospace user-style bubble with the localized group name `Command input` / `命令输入` and no timestamp, copy, or branch actions. The visible non-command Node activates fresh Chat; reload reconstructs it from the run, while a history window containing only `command/done` keeps only the generic result row. This projection never creates `user/message` or a model turn.
+

 Goal 界面插件（浏览器端部分）：`GoalBar` 条带是 `conversation.input.dock` composer 上下文堆栈中的第二张独立卡片（order 10，位于 Todo 之后、Queue 之前）。活值经 `useProjection('goal')` 到达——host 计算的全量值由历史尾页播种、由 `session/projection` 帧更新——因此本插件不持有领域 store、不设刷新链、不挂事件监听。slot 注入面只携带四个变更动词（edit / pause / resume / clear，经 `ctx.remote.goals` 调用——active 的 goal 提供暂停动作，paused 的提供恢复）；每个动词在调用时从会话当前投影值读取 CAS ref，并将 Remote 调用的拒绝错误内联呈现。由于 React 的 pending 渲染无法拦住同一帧内的点击，横条会同步为变更建立 single-flight 防护；清除成功后，会立即抑制该 goal id 对应的目标显示，直到权威的 null 投影追上。goal 的创建仍归 `/goal` host 命令；加载中、无 goal、已完成和已成功清除的 goal 一律不渲染。
 
+该插件还会通过自有 Conversation Definition 投影每条持久 `/goal` `command/run`。它在通用命令结果 Node 之前构建一个 `command-input` Chat Node，并为该 Node 注册 keyed renderer；renderer 将其呈现为右对齐、使用 14px/22px 等宽字体的用户样式气泡，使用本地化分组名称 `Command input`／`命令输入`，且不含时间戳、复制或分支操作。可见的非命令 Node 会激活新 Chat；重新加载时会根据 run 重建该 Node，而仅包含 `command/done` 的历史窗口只保留通用结果行。该投影绝不会创建 `user/message` 或模型轮次。
+
 `/client` 的导出接口包括插件本体（`apply`/`inject`）、`GoalBar`/`GoalDock` 组件与注入动词面类型。

 Directories are per-session, resolved lazily through `ctx.models.directoryFor(sessionId)`, and disposed with the session scope. Addressed subagent sessions expose neither entry, and their directory rejects loads, selections, and reconnect refreshes, because ordinary Agent-bound model RPCs would activate persisted child history outside the direct-parent continuation path.
 
+Every resident directory refetches directly on forwarded `llm/adapters-updated` and `settings/document-updated` owner events. Provider topology, provider catalogs, and the default selection therefore converge without the Host or client runtime deriving a separate model-change alias.

 The DeepSeek step projects `deepseek-official` readiness from that same joined snapshot after earlier onboarding pages complete. It recognizes the official adapter through its `llm-deepseek` configurable-provider declaration, so an undeclared live route with the same provider id is not treated as repairable configuration. A configured credential reference completes the step without rendering, including a read-only launch-environment credential. Only a mounted, active adapter with a missing writable reference shows the page that opens Settings on Models, whose existing setup card exclusively owns key input and `credentials.set`; the step never holds a secret. An absent adapter, inactive route, failed join, read-only deployment, or unusable settings or credential capability completes the step without rendering so onboarding cannot block the product; Models remains the diagnostic surface.
 
-Every edit lands as `settings.mutate` path ops against the stored section — a set per changed field, an unset per cleared one, and a single unset for a deleted provider row. The page only ever holds the REDACTED descriptor, so it mutates the fields it can see rather than rebuilding a section. DeepSeek's `models` is one replace-by-value array: the editor shows inherited effective rows until the first model edit materializes the complete array in the user layer, while reset unsets that override. A row carries the model id and display name; its context window and output cap sit behind the row's own disclosure, with the same fields the pi-ai provider form uses. Either capacity is typed as a count with an optional decimal `K` or `M` suffix (`256K`, `1M`; `1M` is 1000K) and stored as the plain count, spelled back in the shortest form that round-trips. Empty ids, duplicate ids, empty explicit names, and unreadable, non-positive, or fractional capacities fail before any write. A typed API key is judged on its own field the same way: after trimming, it must be non-empty and every character must be printable ASCII (`[\x21-\x7E]`), which is exactly what an HTTP header value can carry — the twin of `normalizeApiKey` in `@deepseek-ai/dsh-llm`, mirrored here because the source-plane split forbids importing it. A value matching a pasted `NAME=value` environment line or wrapped in matching quotes is refused as the same format failure; that pasted-line check runs only in the browser, since a false positive in a resolver would leave the environment refusing the key as well. A field holding only whitespace fails rather than being silently dropped, while an empty field is not a failure at all: it means keep the stored key on an editor card, and authenticate some other way on a create card. A refused key blocks both the write and the endpoint interrogation, so the page never spends a round trip to be told what the field already says. Each settings write carries the card's current `revision`, so a concurrent write from another tab or an external `settings.yaml` edit is refused as `settings-conflict`; after settings commit, the card adopts the returned redacted user subtree and revision before storing the credential, which makes a failed credential stage retry only that stage. Deletion removes a configured, writable credential only when the profile names the page's derived `<ROUTE>_API_KEY` target, then unsets the profile; both operations are idempotent, and a partial failure remains in the identified confirmation dialog for retry. Environment credentials, custom references, and credentials whose target cannot be identified remain untouched. The page refetches on the pushed invalidations (`settings/changed`, `credentials/changed`, `models/changed`, and `connection/reset`) once it has loaded, so an external `settings.yaml` edit, a second tab, or a settings-born route converges without polling.
+Every edit lands as `settings.mutate` path ops against the stored section — a set per changed field, an unset per cleared one, and a single unset for a deleted provider row. The page only ever holds the REDACTED descriptor, so it mutates the fields it can see rather than rebuilding a section. DeepSeek's `models` is one replace-by-value array: the editor shows inherited effective rows until the first model edit materializes the complete array in the user layer, while reset unsets that override. A row carries the model id and display name; its context window and output cap sit behind the row's own disclosure, with the same fields the pi-ai provider form uses. Either capacity is typed as a count with an optional decimal `K` or `M` suffix (`256K`, `1M`; `1M` is 1000K) and stored as the plain count, spelled back in the shortest form that round-trips. Empty ids, duplicate ids, empty explicit names, and unreadable, non-positive, or fractional capacities fail before any write. A typed API key is judged on its own field the same way: after trimming, it must be non-empty and every character must be printable ASCII (`[\x21-\x7E]`), which is exactly what an HTTP header value can carry — the twin of `normalizeApiKey` in `@deepseek-ai/dsh-llm`, mirrored here because the source-plane split forbids importing it. A value matching a pasted `NAME=value` environment line or wrapped in matching quotes is refused as the same format failure; that pasted-line check runs only in the browser, since a false positive in a resolver would leave the environment refusing the key as well. A field holding only whitespace fails rather than being silently dropped, while an empty field is not a failure at all: it means keep the stored key on an editor card, and authenticate some other way on a create card. A refused key blocks both the write and the endpoint interrogation, so the page never spends a round trip to be told what the field already says. Each settings write carries the card's current `revision`, so a concurrent write from another tab or an external `settings.yaml` edit is refused as `settings-conflict`; after settings commit, the card adopts the returned redacted user subtree and revision before storing the credential, which makes a failed credential stage retry only that stage. Deletion removes a configured, writable credential only when the profile names the page's derived `<ROUTE>_API_KEY` target, then unsets the profile; both operations are idempotent, and a partial failure remains in the identified confirmation dialog for retry. Environment credentials, custom references, and credentials whose target cannot be identified remain untouched. Once loaded, the page subscribes directly to forwarded `settings/document-updated`, `credentials/updated`, and `llm/adapters-updated` owner events, plus local `connection/reset`, so an external `settings.yaml` edit, a second tab, or a settings-born route converges without polling.

 ## Hover cards
 
 `HoverCard` keeps its portaled preview reachable across the anchor gap with a pointer-leave grace. A consumer may also pass `copyText`: the card then exposes button semantics for pointer and keyboard activation, includes that value after the `copyLabel` prefix in its accessible name, writes the exact value through the package clipboard helper, and temporarily replaces its content with `copiedLabel` only after the host accepts the write. A non-collapsed text selection intersecting the card suppresses pointer-click activation, while success feedback retains the original card height and clears when the card closes or after one second. `copyLabel` and `copiedLabel` are label props because this zero-cordis atom cannot read the application locale; omitting `copyText` preserves the read/select-only card. Historical rationale: [the archived hover-card copy note](../../../.agents/notes/archived/feature/2026-07-31-hover-card-click-copy.md).
 
+## Toast
+
+`Toast` is the transient top banner: it slides in, holds at full opacity for three seconds, fades over one second, then calls `onDone` so the owner can unmount it. It renders `role="alert"` with an optional leading icon slot and takes its copy as a required prop (zero-cordis: the owner localizes). It body-portals with `pointer-events: none`, sits 120px from the viewport top, and centers horizontally over the optional `anchor` element (re-measured on window resizes) — the composer passes its card so the banner centers over the chat column rather than the whole window — falling back to the viewport center without one. Re-showing the same message requires a remount — owners key the element by a per-show sequence so an identical repeated message restarts the hold-and-fade cycle instead of silently reusing the faded banner. Under `prefers-reduced-motion: reduce` the slide-in is dropped and only the delayed fade remains. It layers above the ui-attachment image lightbox so a failure reported during a preview stays readable.
+
 ## Markdown rendering
 
 `MarkdownText` renders GFM and `$…$`, `$$…$$`, `\(…\)`, and `\[…\]` TeX math from untrusted assistant output through React elements, with math typeset by KaTeX and trusted commands disabled; block-level same-line `$$…$$` is display math, including `\tag{}`. A narrow micromark extension lets asterisk strong emphasis ending in punctuation close before adjacent CJK text, where prose normally omits the whitespace CommonMark requires; single-asterisk emphasis, non-CJK adjacency, escapes, code, and math retain upstream parsing. It omits raw HTML, neutralizes relative and non-HTTP(S)/mailto links, opens HTTP(S) links with safe external-link attributes, and renders absolute HTTP(S) images without a referrer; relative paths, absolute local paths, `file:` URLs, and unsupported schemes retain their alt text. Inline code whose complete value is an absolute HTTP(S) URL keeps its code styling and gains the same safe external anchor; commands, partial URLs, other schemes, and fenced code remain inert. An optional `fileMentions` resolver lets the owning view link inline code that names a real file: the token keeps code styling and gains a button wired to the resolved opener, with the resolver's accessible label and full-path `title`. The renderer never guesses at what looks like a path — an unresolved token stays inert, mentions apply to settled renders only (the streaming cache must not bake in handlers that could go stale), and a token inside an anchor stays inert because a button cannot nest there. While a reply streams, `MarkdownText` parses incrementally: all but the trailing two blocks freeze as cached React elements and only the source tail behind them re-parses per chunk, so per-chunk work tracks the tail instead of the whole reply ([mechanism and DOM-parity contract](../../../.agents/notes/implemented/architecture/2026-08-06-web-markdown-incremental-ast-renderer.md)). `MessageText` remains the literal-text primitive for user-authored content. `extractMarkdownPlainText` removes Markdown presentation markup for compact labels while preserving raw HTML as literal text. Element spacing, responsive images, tables, links, and inline code use the same `--dsw-alias-markdown-*` / `--dsw-font-markdown-*` tokens as deepsuite `@deepseek/md`. Fenced blocks render through `CodeBlock` (language banner, copy control, shiki for the registered grammars).

 ## 悬浮卡片
 
 `HoverCard` 通过指针离开宽限期，使采用 portal 渲染的预览在跨过与锚点之间的间隙时仍可触及。消费方还可传入 `copyText`：此时卡片为指针与键盘激活提供按钮语义，其无障碍名称会在 `copyLabel` 前缀后包含该值，通过包内剪贴板辅助函数原样写入该值，并且只有宿主接受写入后，才会临时将内容替换为 `copiedLabel`。与卡片相交的非折叠文本选区会阻止指针点击激活；成功反馈保持卡片原有高度，并随卡片关闭或在一秒后清除。`copyLabel` 和 `copiedLabel` 采用 label prop，是因为这个 zero-cordis 原子组件无法读取应用 locale；省略 `copyText` 时，卡片维持只读且可选择文本的行为。历史依据见[已归档的悬浮卡片复制 Agent Note](../../../.agents/notes/archived/feature/2026-07-31-hover-card-click-copy.md)。
 
+## Toast
+
+`Toast` 是顶部的短时横幅：滑入后满不透明度停留三秒，再用一秒淡出，随后调用 `onDone` 由持有方卸载。它渲染 `role="alert"`，带可选的前置图标插槽，文案是必填 prop（零 cordis，由持有方本地化）。它经 body portal 渲染且 `pointer-events: none`，距视口顶部 120px，水平中心跟随可选的 `anchor` 元素（窗口尺寸变化时重测）——composer 传入自己的卡片，横幅因此在聊天列而非整个窗口上居中——不传则回退到视口居中。重复展示同一条消息需要重新挂载，持有方用每次展示递增的序号作为 key，让相同文案重新走完停留与淡出，而不是静默复用已淡出的横幅。`prefers-reduced-motion: reduce` 下去掉滑入，只保留延迟淡出。它的层级高于 ui-attachment 的图片灯箱，预览打开时报出的失败仍然可读。
+
 ## Markdown 渲染
 
 `MarkdownText` 通过 React 元素渲染来自不受信任 assistant 输出的 GFM 与 `$…$`、`$$…$$`、`\(…\)` 和 `\[…\]` TeX 公式，公式由 KaTeX 排版并禁用受信任命令；块级同一行 `$$…$$` 是显示公式并支持 `\tag{}`。一个小范围的 micromark 扩展允许由星号标记、以标点结尾的粗体在紧邻的 CJK 文本前闭合，以适应 CJK 文本通常省略 CommonMark 所要求空格的写法；单星号强调、紧邻非 CJK 文本的情况、转义、代码与数学公式仍沿用上游解析行为。它会省略原始 HTML，使相对链接及非 HTTP(S)/mailto 链接失效，以安全的外部链接属性打开 HTTP(S) 链接，并在不发送 referrer 的情况下渲染采用绝对 HTTP(S) URL 的图片；相对路径、绝对本地路径、`file:` URL 与不受支持的 scheme 会保留其 alt 文本。完整内容为绝对 HTTP(S) URL 的行内代码会保留代码样式，并获得同样安全的外部链接；命令、非完整 URL、其他 scheme 与围栏代码仍不会成为链接。可选的 `fileMentions` 解析器让持有该组件的视图为命名真实文件的行内代码添加可点击入口：token 保留代码样式，并获得一个连接到解析所得 opener 的按钮，按钮带有解析器提供的无障碍标签和以完整路径为值的 `title`。渲染器绝不猜测哪些内容像路径：未解析的 token 保持不可交互；文件提及仅应用于已定稿的渲染（流式缓存不得固化可能过期的 handler）；锚点内的 token 也保持不可交互，因为按钮不能嵌套其中。回复流式输出期间，`MarkdownText` 增量解析：除末尾两个块外全部冻结为缓存的 React 元素，每个分片只重新解析其后的源文本尾部，因此每分片的工作量跟随尾部而非整个回复（[机制与 DOM 一致性约定](../../../.agents/notes/implemented/architecture/2026-08-06-web-markdown-incremental-ast-renderer.md)）。`MessageText` 仍是用户创作内容使用的字面文本原语。`extractMarkdownPlainText` 会移除 Markdown 呈现标记以用于紧凑标签，同时将原始 HTML 保留为字面文本。元素间距、响应式图片、表格、链接与行内代码使用与 deepsuite `@deepseek/md` 相同的 `--dsw-alias-markdown-*` / `--dsw-font-markdown-*` token。围栏代码块通过 `CodeBlock` 渲染（语言横幅、复制控件，以及对已注册语法使用 shiki）。

-Settings ownerless-copy and product-onboarding plugin: registers everything on the Settings surface that belongs to no single feature — the shell's trigger/header/close chrome content, the local configuration-file action, the General section and its `settings.general.item` slot, the `settings` dictionaries, and the first ordered welcome step. Feature-owned rows (Permission, Language, Appearance), sections (Models), and conditional onboarding steps stay with their feature packages.
+Settings shell, ownerless-copy, and product-onboarding plugin. It occupies `sidebar.settings` with the trigger chrome and modal settings panel, projects the `settings.section` ledger into the navigation and the `settings.onboarding` ledger into one mounted page at a time, and registers everything on the Settings pages that belongs to no single feature — the trigger/header/close chrome content, the local configuration-file action, the General section and its `settings.general.item` slot, the `settings` dictionaries, and the first ordered welcome step. The slot types it renders into belong to ui-settings, the settings domain base; only the shell's own contract types live here, because they reference ui-sidebar's slot type and the base layer must depend on no `ui-*` package. Feature-owned rows (Permission, Language, Appearance), sections (Models), and conditional onboarding steps stay with their feature packages.
+
+The shell ships no copy of its own — all text arrives from registrants. Nav labels may be locale-following thunks, so the nav projection resolves them through `resolveSlotLabel` and re-renders on the section ledger bump or the locale revision (an optional `ctx.get('locale')` read; no hard locale dependency). The onboarding ledger projects in ascending order and mounts exactly one page at a time; the takeover chrome (body-level stage, mask, app-root `inert`) belongs to the step itself through ui-primitives' `OnboardingSurface`, so a mounted step still resolving its private facts renders null and neither paints nor blocks anything — the shell shows no empty stage while a step decides. The active registrant receives its id, `complete()`, and an `openSection(id)` callback; completing or skipping transfers ownership to the next entry. Registrants own durable completion, capability readiness, copy, mutations, and the surface wrap, so independently registered flows cannot stack and the shell does not become a second configuration fact source.
 
 A loopback browser loads the provider's `hasDocument` capability through `settings.describe` and renders **Open configuration file** only when the Host confirms that a provider-owned local document can be prepared. The action sends the pathless, loopback-only `settings.openDocument` request; the Host resolves the provider path again, materializes an absent document, and hands it to a native text editor (`open -t` on macOS, bypassing a browser file association; the desktop file association on Linux and Windows; Windows association after `wslpath -w` translation on WSL). Open failures keep the action available and render a localized error. Reopening the dialog or reconnecting refreshes availability after a transient read failure or Host topology change. Remote browsers never register the action and never issue the privileged settings read.
 
-`src/onboarding-copy.ts` is the single editable owner of the complete notice plus `WELCOME_NOTICE_VERSION`; both supported GUI locales intentionally render the same Chinese copy. The Host half registers `ui-onboarding` in the user-settings seam. A loopback browser compares `welcomeNoticeVersion` for exact equality and writes the current value only after Continue succeeds. The path mutation is idempotent across tabs and preserves sibling settings, while `host/settings-changed` makes an externally acknowledged notice advance without a reload. A non-loopback browser cannot access the privileged settings API: it still presents the notice, but Continue advances only the current browser process and a reload presents the notice again. A different version deliberately presents the notice again. The welcome page preserves every authored paragraph, gives the requested clause in the final paragraph the sole emphasis, initially focuses the title, and has no close, Escape, mask-click, or secondary path. None of its copy or acknowledgement enters a Session log or model request. The notice identifies `DSH_TELEMETRY_DISABLED=1` as the telemetry opt-out.

-设置界面无特定功能归属的文案与产品引导插件：在设置界面注册所有不属于单一功能的内容，包括外壳的触发器、标题栏与关闭控件内容、本地配置文件操作，「通用」分区及其 `settings.general.item` slot、`settings` 字典，以及第一个有序欢迎步骤。归具体功能所有的行（「权限」、「语言」、「外观」）、分区（「模型」）和条件式首次使用引导步骤仍由各自的功能包提供。
+设置外壳、无特定功能归属文案与产品引导插件。它以触发控件和模态设置面板占用 `sidebar.settings`，把 `settings.section` 账本投影成导航、把 `settings.onboarding` 账本投影成每次只挂载一页的引导流程，并在设置页面上注册所有不属于单一功能的内容：触发器、标题栏与关闭控件内容、本地配置文件操作，「通用」分区及其 `settings.general.item` slot、`settings` 字典，以及第一个有序欢迎步骤。它渲染进的那些 slot 类型归 ui-settings——设置领域底座——所有；只有外壳自身的契约类型放在这里，因为它们引用 ui-sidebar 的 slot 类型，而底座不得依赖任何 `ui-*` 包。归具体功能所有的行（「权限」、「语言」、「外观」）、分区（「模型」）和条件式首次使用引导步骤仍由各自的功能包提供。
+
+外壳不自带文案：所有文本都来自注册方。导航 label 可以是跟随语言的 thunk，因此导航投影经 `resolveSlotLabel` 解析，并在分区账本更新或 locale revision 变化时重新渲染（`ctx.get('locale')` 可选读取，无硬 locale 依赖）。首次使用引导记录按升序投影，每次只挂载一个页面；接管界面框架（body 层级的展示层、遮罩、应用根节点 `inert`）经 ui-primitives 的 `OnboardingSurface` 由步骤自身持有，因此已挂载但仍在判定私有事实的步骤渲染 null 时不绘制也不阻塞任何内容——步骤判定期间外壳不会露出空白展示层。当前注册方会收到该条目的 id、`complete()` 和 `openSection(id)` 回调；完成或跳过当前页面后，所有权转交给下一项。持久化完成状态、能力就绪状态、文案、变更操作以及展示层包装均由注册方持有，因此独立注册的流程无法堆叠，外壳也不会成为第二个配置事实来源。
 
 回环浏览器通过 `settings.describe` 加载提供方的 `hasDocument` 能力，且只有在 Host 确认可准备好一份由提供方持有的本地文档时才渲染**打开配置文件**。该操作发送无路径参数且仅限回环访问的 `settings.openDocument` 请求；Host 会再次解析提供方路径、在文档缺失时将其创建出来，并交给原生文本编辑器（macOS 上使用 `open -t`，绕过浏览器文件关联；Linux 和 Windows 上使用桌面文件关联；WSL 上经 `wslpath -w` 转换后使用 Windows 文件关联）。打开失败时该操作仍可使用，并渲染本地化错误。临时读取失败或 Host 拓扑变化后，重新打开对话框或重新连接会刷新可用性。远程浏览器从不注册该操作，也从不发起这项特权设置读取。
 
-`src/onboarding-copy.ts` 是完整通知文案和 `WELCOME_NOTICE_VERSION` 的唯一可编辑来源；GUI 支持的两种 locale 都有意渲染同一份中文文案。宿主端在用户设置 seam 中注册 `ui-onboarding`。回环浏览器会比较 `welcomeNoticeVersion` 是否精确相等，仅在「继续」操作成功后写入当前值。该路径变更在不同标签页间幂等，并会保留同级设置；`host/settings-changed` 则让页面在通知被外部确认后，无需重新加载即可推进。非回环浏览器不能访问受保护的设置 API：它仍会显示通知，但「继续」只推进当前浏览器进程，重新加载后会再次显示通知。版本不同时，系统也会有意重新显示通知。欢迎页保留原文的每个段落，仅强调最后一段中指定的句段，初始焦点落在标题上，并且没有关闭操作、Escape、点击遮罩或次要操作路径。其文案和确认状态均不会进入会话日志或模型请求。通知明确以 `DSH_TELEMETRY_DISABLED=1` 作为遥测关闭方式。

-Settings shell plugin: a pure composition face. It occupies `sidebar.settings` with the trigger chrome and modal settings panel, and declares the slots registrants fill: `settings.trigger` / `settings.header` / `settings.close` (chrome content), `settings.action` (ordered content-header actions), `settings.section` (one page per feature), and `settings.onboarding` (ordered feature-owned pages in a full-viewport stage). The shell ships no copy of its own — all text arrives from registrants (ui-settings-general owns chrome, General, and the product notice; features own their actions, sections, rows, and conditional onboarding pages). Nav labels may be locale-following thunks, so the nav projection resolves them through `resolveSlotLabel` and re-renders on the section ledger bump or the locale revision (an optional `ctx.get('locale')` read; no hard locale dependency).
+The settings domain's base layer, with two roles and no presentation of its own. It provides `ctx.settingsScope`, the Host transport every preference row binds its durable namespace section through, and it declares the settings slot types registrants fill: `settings.trigger` / `settings.header` / `settings.close` (chrome content), `settings.action` (ordered content-header actions), `settings.section` (one page per feature), and `settings.onboarding` (ordered feature-owned pages). It depends on no `ui-*` presentation package, so any feature that owns a preference can reach it; the settings SHELL — the `sidebar.settings` occupant, its navigation, and the chrome — lives in ui-settings-general, because a shell dependency on ui-sidebar would close a reference graph cycle through ui-layout and ui-theme. The shell's own contract types live beside the shell for the same reason.
 
-The shell projects the onboarding ledger into ascending order and mounts exactly one page at a time; the takeover chrome (body-level stage, mask, app-root `inert`) belongs to the step itself through ui-primitives' `OnboardingSurface`, so a mounted step still resolving its private facts renders null and neither paints nor blocks anything — the shell shows no empty stage while a step decides. The active registrant receives its id, `complete()`, and an `openSection(id)` callback; completing or skipping transfers ownership to the next entry. Registrants own durable completion, capability readiness, copy, mutations, and the surface wrap, so independently registered flows cannot stack and the shell does not become a second configuration fact source.
+The plugin injects nothing and waits for nothing: `ctx.settingsScope.bind(spec)` resolves the wire face through the CALLER's context at call time, so the bound scope's disposer belongs to the calling fiber, and the caller injects `connection` for the transport and `remote` for the invalidation. Listeners exist before the first background read starts, so a row's activation never blocks on the settings transport. A bound scope reloads on the forwarded `settings/document-updated` event for its own namespace and on `connection/reset`. Writes carry one field path and the last known namespace revision as `expectedRevision`; a rejected or failed write re-reads unless a newer write already superseded it, and a stale read never publishes over a newer one. Without a `decode` in the spec, a section that is not a plain object, fails its rehydrated schema, or carries a schema envelope this client cannot rehydrate publishes no value at all, so a row renders its own absent state instead of a half-decoded one.

 ## Known Limitations and Deferred Work
 
-- **Panel is browser-preference scope only** — host-side settings surfaces (permission mode, tool-call mode) have no RPC backing yet; their skeletons live in ui-settings-general.
+- **Remote browsers get no durable settings** — the settings RPCs are loopback-only, so a scope bound in a non-loopback browser starts `unavailable` and never crosses the wire; every row it backs is inert there.
+- **One field per write** — `set` sends a single `set` op, so a row that must move two fields together has no transaction and publishes two revisions.

-设置外壳插件：一个纯组合表层。它以触发控件和模态设置面板占用 `sidebar.settings`，并声明由注册方填充的 slot：`settings.trigger`／`settings.header`／`settings.close`（界面框架内容）、`settings.action`（内容标题栏中的有序操作）、`settings.section`（每项功能一页）和 `settings.onboarding`（由各功能持有、显示在全视口展示层中的有序页面）。外壳不自带文案：所有文本都来自注册方（ui-settings-general 拥有界面框架、「通用」分区和产品声明；各功能拥有各自的操作、分区、行和条件式首次使用引导页面）。导航 label 可以是跟随语言的 thunk，因此导航投影经 `resolveSlotLabel` 解析，并在分区账本更新或 locale revision 变化时重新渲染（`ctx.get('locale')` 可选读取，无硬 locale 依赖）。
+设置领域的底座，承担两项职责，本身不含任何呈现内容。它提供 `ctx.settingsScope`——每个偏好设置行绑定自己那份持久化命名空间分区所用的宿主传输层；并声明由注册方填充的设置 slot 类型：`settings.trigger`／`settings.header`／`settings.close`（界面框架内容）、`settings.action`（内容标题栏中的有序操作）、`settings.section`（每项功能一页）和 `settings.onboarding`（由各功能持有的有序页面）。它不依赖任何 `ui-*` 呈现包，因此任何持有偏好设置的功能都能够到它；设置**外壳**——`sidebar.settings` 占位方、它的导航与界面框架——位于 ui-settings-general，因为外壳一旦依赖 ui-sidebar，就会经 ui-layout 与 ui-theme 闭合出一条引用图环路。外壳自身的契约类型出于同一原因与外壳放在一起。
 
-外壳将首次使用引导记录按升序投影，每次只挂载一个页面；接管界面框架（body 层级的展示层、遮罩、应用根节点 `inert`）经 ui-primitives 的 `OnboardingSurface` 由步骤自身持有，因此已挂载但仍在判定私有事实的步骤渲染 null 时不绘制也不阻塞任何内容——步骤判定期间外壳不会露出空白展示层。当前注册方会收到该条目的 id、`complete()` 和 `openSection(id)` 回调；完成或跳过当前页面后，所有权转交给下一项。持久化完成状态、能力就绪状态、文案、变更操作以及展示层包装均由注册方持有，因此独立注册的流程无法堆叠，外壳也不会成为第二个配置事实来源。
+该插件不注入任何服务、也不等待任何服务：`ctx.settingsScope.bind(spec)` 在调用时经**调用方**的 context 解析线路面，因此绑定所得 scope 的 disposer 归调用方 fiber 所有，而由调用方注入 `connection` 取得传输层、注入 `remote` 取得失效通知。监听器在首次后台读取启动之前就已存在，因此某一行的激活绝不会阻塞在设置传输层上。已绑定的 scope 会在收到属于自己命名空间的转发 `settings/document-updated` 事件时、以及在 `connection/reset` 时重新读取。写入携带单一字段路径以及最近已知的命名空间 revision 作为 `expectedRevision`；被拒绝或失败的写入会重新读取，除非已有更新的写入取代了它，而过期的读取绝不会覆盖发布更新的结果。若 spec 未提供 `decode`，则分区不是普通对象、未通过其重建后的 schema 校验、或携带本客户端无法重建的 schema 信封时，一律不发布任何值，于是行渲染自己的缺失状态，而不是一份半解码的值。

 ## 已知限制与暂缓事项
 
-- **面板仅涵盖浏览器偏好设置**：宿主侧设置表层（权限模式、工具调用模式）尚无 RPC 支撑；其骨架位于 ui-settings-general。
+- **远程浏览器没有持久化设置**：设置 RPC 仅限 loopback，因此在非 loopback 浏览器中绑定的 scope 以 `unavailable` 起步且从不跨线路，它支撑的每一行在那里都是无效的。
+- **每次写入仅一个字段**：`set` 只发送单个 `set` op，因此需要同时改动两个字段的行没有事务可用，会发布两个 revision。

Results filter by `startsWith(query)`.
 
 A pick lands the literal `/name ` text and the prompt ships the same literal ([slash-pipeline Agent Note](../../../.agents/notes/implemented/architecture/2026-07-25-web-input-machine-and-slash-pipeline.md)) — this source implements no adjudication hooks and no reference codec. Determinism lives host-side: the pre-step gesture boundary (`dsh-tool-skill`) recognizes whitespace-bounded `/name` tokens naming user-invocable skills anywhere in a user message and injects the rendered `<skill_content>` for every entry point, so a menu pick, a hand-typed token, and a TUI/ACP prompt all load the skill the same way. A name shared with a host command still resolves to the command: adjudication claims the line client-side before it ever becomes a prompt — deliberate precedence, matching peer products. The list RPC rides the plugin's root-context connection captured at registration — the source never reads services off a per-call argument; draft chip visuals derive from the `lexicon` scan.

-Trajectory renders a turn-aware event ledger with selectable User, Assistant, Tool, and nested Subtool records. Thick rules mark Turn boundaries, compact inline markers identify Steps, and the main ledger keeps only index, event, and content; selection opens a local inspector for token usage, duration, Input, Output, and Timing. Scrollable Summary regions keep their scrollbar thumbs transparent until the region is hovered or contains keyboard focus, without changing the reserved scroll geometry. A standalone compaction request appears chronologically in its own `Between turns` section, while a numbered compaction remains inside its owning turn. Long ledgers open at the current tail, load one older page when the user reaches the loaded range's top, and mount only the visible row window plus a small overscan; request-only separators share the next measurable virtual item, while semantic row keys and ARIA indexes survive prepends. Selection, timeline navigation, folding, search, and Request totals cover the currently loaded window. The ledger covers records with an explicit loading row until the initial tail is positioned and while an older page is pending. A fixed Overview above the ledger projects real record start/duration timing from left to right; when earlier records remain unloaded and the viewport includes the loaded domain's start, a neutral ellipsis control identifies the omitted prefix and loads one earlier page without assigning unknown history fabricated duration. Assistant spans divide recorded TTFT from decoding, and a 500 ms hover reveals exact clock and duration details. Dragging an interval focuses the ledger on every record active at any point in that inclusive range, while clearing the selection restores the full loaded ledger. Wheel gestures zoom the time domain. A right-button click clears the selected interval, while a right-button drag pans an already zoomed viewport without changing it. The initial view and streaming updates stay at the tail; scrolling upward suspends following so new records do not interrupt inspection of earlier rows. Content-only stream frames preserve virtual row keys and heights, reuse measurements, and do not issue repeated tail-scroll writes. The toolbar's Export button downloads the session log — the root plus every subagent descendant — as a ZIP streamed by the host (`GET /api/session.export`): every file is the session's stored artifact text verbatim (`session.jsonl` at the root, `subagents/<id>/session.jsonl` for descendants; no manifest, byte-identical to the backend's durable artifact), and every image any included log references sits under `media/<attachmentId>.<ext>`. Fixture mode (no host) answers 404 for the export. Completed replies retain assembled blocks, timing, and usage in Trajectory target State, while the shared Session window keeps the raw Events. Trajectory asks the conversation shell to float the composer over the full-height ledger, while its responsive vertical scrollers reserve the composer's live height so final rows remain reachable. Trajectory-owned Definitions assemble business records, including cancellation-frozen Assistant and Tool records, from the shared Session window, so Trajectory neither reads nor changes the Chat conversation snapshot.

+# @deepseek-ai/dsh-client-ui-workflow-run
+
+English | [中文](README.zh.md)
+
+The browser plugin that reconstructs durable top-level workflow runs as independent Chat nodes. It consumes the four `tool-workflow/*` Session events owned by [`dsh-tool-workflow`](../../workflow/tool-workflow/README.md), registers one `ConversationNodeDefinition`, and renders through the keyed `conversation.chat.node` slot without changing the existing workflow tool card.
+
+## Durable state and replay
+
+`tool-workflow/run-start` creates one Context keyed by `runId`; member starts, member endings, and the run ending update that Context in log order. A history tail containing only updates remains pending until an older page supplies the unique start, after which prepend, complete replay, and live append produce the same state. A closed Turn or Step with missing terminal events presents the affected run or members as interrupted without changing the tool result.
+
+Phase groups come only from members that actually started. Exact phase strings share a group, an omitted phase is distinct from the empty string, and settlement changes status without removing or reordering members.
+
+## Presentation and navigation
+
+The run and each phase have independent disclosure state. The run uses a 32-pixel `--dsw-alias-bg-module-platform` row with persistent right/down chevrons and an inline state dot plus status text, without a badge. Phases use 32-pixel disclosure rows with title and member count in the flexible main area and a fixed precise aggregate-status tail, without another dot. Members use a 16-pixel dot slot, a truncating name area, and a fixed 64-pixel status column. A running run initially expands; a terminal run loaded from history initially collapses. Local choices survive data updates while the keyed node remains mounted and reset only on a full remount.
+
+A member opens a child Session only while every current fact agrees: the member is running, the child id is in the ordinary Session list, the row has `origin: 'subagent'`, its `parentId` is the current Session, and the list row is still running. Underlined member text is the only visible navigation affordance; keyboard focus draws a two-pixel business-primary ring around the name area, while status copy remains `Running`. The component calls only the injected ordinary `sessions.open(id)` action; remote, addressed-only, wrong-parent, or terminal rows remain non-interactive.
+
+## Composition
+
+The package registers its Definition, locale dictionary, and `workflow-run` renderer as Cordis effects. Removing the client entry retracts all three contributions. The shipped Web bundle includes the plugin after `ui-conversation` and `ui-tool`.
+
+## Model Experience
+
+None, as this package renders durable Session facts for humans and adds no prompt, tool schema, request content, or model-visible result.
+
+#### KV Cache effect
+
+None.
+
+## Known Limitations and Deferred Work
+
+- Only top-level calls through `dsh-tool-workflow` produce these records; nested Code Mode calls and direct `WorkflowService` consumers do not.
+- Navigation is intentionally live-only. Terminal members remain visible for review but never expose a cold-session opener from this node.
+- The node shows run, phase, member identity, and status only; scripts, outputs, errors, logs, usage, static topology, and controls remain outside this surface.

+# @deepseek-ai/dsh-client-ui-workflow-run
+
+[English](README.md) | 中文
+
+这个浏览器插件把持久化的顶层工作流运行重建为独立 Chat 节点。它消费由 [`dsh-tool-workflow`](../../workflow/tool-workflow/README.md) 拥有的四类 `tool-workflow/*` Session 事件，注册一个 `ConversationNodeDefinition`，并通过 keyed `conversation.chat.node` slot 渲染，不改变现有工作流工具卡。
+
+## 持久状态与回放
+
+`tool-workflow/run-start` 以 `runId` 创建唯一 Context；成员开始、成员结束和运行结束事件按日志顺序更新该 Context。只有 update 的历史尾页会保持 pending，直到更早页面补入唯一 start；此后 prepend、完整回放和实时 append 得到相同状态。若所属 Turn 或 Step 已关闭但终点事件缺失，界面把相应运行或成员显示为已中断，而不改写工具结果。
+
+阶段组只来自真正开始过的成员。完全相同的阶段字符串归入同一组，字段缺省与空字符串保持不同身份；成员结算只改变状态，不删除或重排成员。
+
+## 展示与导航
+
+运行和每个阶段分别拥有本地 disclosure 状态。运行使用 32 像素 `--dsw-alias-bg-module-platform` 背景行，常驻向右／向下 chevron，并以内联状态点加状态文字表达结局，不使用胶囊。阶段使用 32 像素 disclosure 行，在可伸缩主区显示标题与成员数，在固定尾部精确显示聚合状态且不重复状态点。成员使用 16 像素状态点槽、可省略名称区和固定 64 像素状态列。运行中记录首次挂载时展开，从历史加载的终态记录首次挂载时折叠。只要 keyed 节点仍挂载，本地选择就在数据更新时保持；只有完整 remount 才重新初始化。
+
+只有所有实时事实同时成立时，成员才可打开子 Session：成员仍在运行、子 id 位于普通 Session 列表、列表行为 `origin: 'subagent'`、`parentId` 等于当前 Session，且列表行仍标记运行。带下划线的成员文字是唯一可见导航提示；键盘聚焦时，名称区显示 2 像素 business-primary 焦点环，右侧状态仍只显示“运行中”。组件只调用注入的普通 `sessions.open(id)`；远程、仅地址化、父级不符或终态的行都不可交互。
+
+## 装配
+
+本包把 Definition、locale 字典和 `workflow-run` renderer 都注册为 Cordis effect；移除客户端 entry 会撤销三者。shipped Web bundle 在 `ui-conversation` 与 `ui-tool` 之后装配该插件。
+
+## Model Experience
+
+无，因为本包只为人类展示持久 Session 事实，不增加 prompt、工具 schema、请求内容或模型可见结果。
+
+#### KV Cache effect
+
+无。
+
+## Known Limitations and Deferred Work
+
+- 只有经 `dsh-tool-workflow` 发起的顶层调用会生成这些记录；嵌套 Code Mode 调用和直接 `WorkflowService` 消费方不会生成。
+- 导航刻意只面向实时运行。终态成员继续保留供复盘，但本节点永不为其提供冷 Session 入口。
+- 节点只显示运行、阶段、成员身份与状态；脚本、输出、错误、日志、用量、静态拓扑和控制操作都不属于本界面。

Ambient process-environment changes are not observable and never emit. Consumers do not need the event (they re-resolve per operation); it exists for configuration UIs refreshing a "configured" badge. Its declaration lives in the client-safe `./types` subpath export together with the `CredentialRef` type it names (the package root re-exports the type), so a consumer outside the Host compilation face reads the very signature the Host emits instead of restating it.
 
 The shadowing rule on `set`/`unset` is deliberate fail-loud: when a read-only source (the live process environment, in the local provider) currently supplies the reference, a write would appear to succeed while resolution keeps returning the shadowing value — the seam rejects instead, and `describe().writable` lets a UI render the reference read-only up front.

 `session.history`'s tail page (`beforeSeq` absent) additionally carries an optional `projections` block — the watermark snapshot of every unit registered on `ctx.sessionProjections` (`@deepseek-ai/dsh-session-projection`), with `asOfSeq` = the last event seq the values reflect (`-1` on an empty log). The gateway also subscribes to the registry's change feed and mints a `session/projection` mux frame per changed unit (`{sessionId, key, value, seq}` — live push state, never logged; clients hold one generic per-session value store under higher-seq-wins). The carrier holds zero domain knowledge (each value passed its unit's own schema inside the registry; the wire schemas keep `values`/`value` wide); loadOlder pages never carry the block, and a composition without the registry serves histories without either surface.
 
-Session-log export is a host-only download surface, not an RPC: `GET /api/session.export?sessionId=…&includeDescendants=true` streams a ZIP whose files are each session's stored artifact text verbatim (the persistence backend's `readRaw` — exact durable bytes decoded from the physical encoding, never a reconstruction from parsed events), root under its original base name plus each subagent descendant under `subagents/<id>/`, and every image any included log references under `media/<attachmentId>.<ext>` (read and verified from the attachment store; a shared image appears once). Compression runs on the host with fflate's streaming Zip API, so the response is chunked as it is produced and the host never holds the whole archive in one buffer, and production yields whenever the response queue fills, so a slow consumer bounds the accumulation (fflate's callback is synchronous — the drain point is the only backpressure). It requires the persistence, session-query, and attachment services: a deployment without any answers 500, a missing root session 404, and a descendant without a stored artifact or a referenced image that cannot be read fails the stream (fail-loud, never silent under-export). The carrier mounts the endpoint; `ApiProxy.downloads.sessionLog` implements it.
+Session-log export is a host-only download surface, not an RPC: `GET /api/session.export?sessionId=…&includeDescendants=true` streams a ZIP whose files are each session's stored artifact text verbatim (the persistence backend's `readRaw` — exact durable bytes decoded from the physical encoding, never a reconstruction from parsed events), root under its original base name plus each subagent descendant under `subagents/<id>/`, and every image any included log references under `media/<attachmentId>.<ext>` (read and verified from the attachment store; a shared image appears once). Each live root or descendant crosses the authoritative `SessionStore.flush` durability barrier immediately before its raw artifact read; cold sessions have no in-memory work to flush. Compression runs on the host with fflate's streaming Zip API at validated `sessionExportCompressionLevel` 0–9 (default 6), so deployments can trade CPU and latency against archive size; the response is chunked as it is produced and the host never holds the whole archive in one buffer. Once the response queue reaches its 64 KiB byte high-water mark, production waits until consumer pull restores positive capacity; fflate's synchronous callback can overshoot that bound only by the output of one bounded input push. Request abort and response-body cancellation stop lineage and artifact work, terminate the active compressor, and propagate as cancellation rather than an HTTP 500. It requires the persistence, session-query, and attachment services: a deployment without any answers 500, a persistence backend without per-session raw artifacts answers 501, a missing root session answers 404, and a descendant without a stored artifact or a referenced image that cannot be read fails the stream (fail-loud, never silent under-export). The carrier mounts the endpoint; `ApiProxy.downloads.sessionLog` implements it.
 
 Session titles ride the generic projection pair like every other domain — the history-tail `projections` block plus `session/projection` frames under the `title` key. Titles do not join `session.list`; cold sessions remain metadata-only there until opening or resuming attaches their logs. `session.rename` accepts an explicit user title (resuming a cold session first), delegating to `ctx.sessionTitle.rename` — the accepted `session/title` event pins the title against automatic regeneration — and returns the normalized title plus its event seq so a client settles its `title` projection cell ahead of the push frame; a title that normalizes to empty returns `title-invalid`.

 `agentPreset.read`, `copy`, `openDocument`, and `remove` manage the compositions themselves. `read` reports the text with its `trust`, for the read-only viewer. Authoring is copy-only: `copy` takes `{ from, agentPreset, name? }` — two ids the Host resolves against its own roots plus an optional display name — and copies the source's whole directory, so no composition text crosses the wire and a copy is exactly as loadable as its source; an uncontainable or already-taken id answers `agent-preset-invalid`, and `remove` refuses a shipped preset as `agent-preset-read-only`. `openDocument` hands one locally authored preset's DIRECTORY to the platform opener — the request carries an id, never a path, so no browser payload can select an arbitrary filesystem target; where the deployment has no native opener the reply is `{ opened: false, path }` for the surface to show as text, a shipped preset is refused like `remove`, and the gateway's `nativeOpen` config pins the capability where platform detection (`canOpenNativePath`) would mislead. These four are loopback-pinned in [`dsh-client-connection`](../../client/connection/README.md): a composition names the plugins a session runs, so reading one is reconnaissance, and copy/remove/openDocument manage the roster and drive the host desktop. `list` and `select` stay ordinary — the roster carries ids and trust and every preset picker needs it, and choosing a preset grants nothing `session.create`'s own `agentPreset` did not, over a default that already carries bash. `list` reports two path-free capability flags: `authorable`, whether the deployment configures a root a new preset could be copied to, and `hasDocument`, whether `openDocument` would open natively rather than answer a path.
 
-The `command.*` and `skill.*` domains expose the host command registry and skill catalog to clients. Every method addresses one session's agent by `sessionId` (a served session always has an Agent; `command.*` resumes cold sessions through the same path as `session.*`, while `skill.list` resolves the project root from the session header without touching the Agent registry). `skill.list` serves the composer's menu: it returns every user-invocable skill with its `modelInvocable` flag, so menus can mark user-only (`disable-model-invocation`) entries whose only invocation path is the slash gesture. Listing is the skill domain's only RPC — invocation itself is an ordinary `session.prompt` whose whitespace-bounded `/name` tokens `dsh-tool-skill` recognizes at the pre-step boundary and answers with injected `<skill_content>` context, so every entry point (Web, TUI, and ACP) shares one deterministic path—including for hand-typed text—with no dedicated invocation wire. `command.execute` runs a slash-command line host-side with pure admission semantics: the response reports whether the line resolved to a handler plus the minted lifecycle `commandId` when it did (correlating the acknowledgment with the flow node), while the outcome rides the durably logged `command/run`/`command/done` lifecycle pair broadcast on the mux stream. Command handlers may legitimately outlast the 30-second transport health deadline, so `command.execute` carries only caller/connection cancellation; that signal cancels the running handler. `host/commands-changed` is the registry-wide catalog invalidation frame: clients refetch `command.list` instead of diffing. `host/session-preset-changed` is its per-session counterpart, framed off the logged `agent-preset/selected` commit: recomposing a blank session's agent re-parents its scope without registering anything, so both catalogs that session's composition decides (`command.list`, `skill.list`) go stale with no registry change to announce it.

-The `settings.*`, `credentials.*`, and `llm.*` domains are the configuration-page wire. The settings domain serves the namespaces addressed by registered configurable providers (`ctx.llm.listConfigurableProviders()`) plus a small explicit allowlist — the Web preferences `locale`, `permission`, `ui-conversation`, and `ui-theme`, and the product-owned `ui-onboarding`; adding a Settings registration alone never makes it remotely readable or writable. Any other namespace answers `settings-not-exposed` — the same answer an unregistered namespace gets, so no caller can enumerate the registry by probing. `settings.describe` returns each exposed namespace's serialized schemastery schema, redacted layered values (resolved/`base`/`user` — a field's presence in `user` marks it user-overridden), the `secrets` slot list, the section's `revision`, and the boolean `hasDocument` capability flag. The browser receives no Host path: pathless `settings.openDocument` asks the provider to materialize its document and then hands the Host-resolved result to the native opener, so no browser payload can select any filesystem target. `settings.update`/`settings.replace` write the user layer; `settings.mutate` applies path ops (`set`/`unset`) against the section as stored, which is the removal path for a client holding the redacted view — rebuilding a section from it and replacing wholesale would delete the secrets the wire never returned.

The browser carrier restricts the whole configuration plane, reads and native actions included (`settings.describe`/`openDocument`/`update`/`replace`/`mutate`, `credentials.describe`/`set`/`unset`), to loopback same-origin requests — the `host.pickDirectory` privileged set. A composition without a settings or credential provider answers those domains with an actionable `internal` error naming the missing plugin.
+The `settings.*`, `credentials.*`, and `llm.*` domains are the configuration-page wire. The settings domain serves the namespaces addressed by registered configurable providers (`ctx.llm.listConfigurableProviders()`) plus a small explicit allowlist — the Web preferences `locale`, `permission`, `ui-conversation`, and `ui-theme`, and the product-owned `ui-onboarding`; adding a Settings registration alone never makes it remotely readable or writable. Any other namespace answers `settings-not-exposed` — the same answer an unregistered namespace gets, so no caller can enumerate the registry by probing. `settings.describe` returns each exposed namespace's serialized schemastery schema, redacted layered values (resolved/`base`/`user` — a field's presence in `user` marks it user-overridden), the `secrets` slot list, the section's `revision`, and the boolean `hasDocument` capability flag. The browser receives no Host path: pathless `settings.openDocument` asks the provider to materialize its document and then hands the Host-resolved result to the native opener, so no browser payload can select any filesystem target. `settings.update`/`settings.replace` write the user layer; `settings.mutate` applies path ops (`set`/`unset`) against the section as stored, which is the removal path for a client holding the redacted view — rebuilding a section from it and replacing wholesale would delete the secrets the wire never returned. Any write may carry `expectedRevision`; a stale one answers `settings-conflict` with both revisions rather than overwriting the writer that landed first, and every other seam refusal folds into `settings-rejected`. Secret-role values never ride any response in any layer; a secret crosses the wire in exactly one direction — inside an `update`/`mutate` payload or `credentials.set`. `credentials.describe` returns value-free views (`configured`/`source`/`writable`), and `credentials.set`/`credentials.unset` map a shadowed-reference refusal onto `credential-rejected`. `llm.providers` merges the configurable-provider directory with live routes (dormant entries carry `active: false`; undeclared live routes append with no settings address) and `llm.models` is the session-independent catalog. `llm.discoverModels` interrogates a provider endpoint the page is still drafting: `settingsNs` selects the adapter family that knows how to read the listing, and the endpoint, protocol, and key come from the form rather than from storage.

Invalidations keep every surface converged without polling. `settings/document-updated` and `credentials/updated` ride the verbatim forwarded-event frame (see below), so a raw settings change whose resolved value is unchanged still reaches clients, and a credential invalidation still carries reference names only, never values. `llm/adapters-updated` is forwarded beside `settings/document-updated`; concrete model consumers subscribe to both owner events directly because topology commits and settings documents can independently change their directories. The browser carrier restricts the whole configuration plane, reads and native actions included (`settings.describe`/`openDocument`/`update`/`replace`/`mutate`, `credentials.describe`/`set`/`unset`), to loopback same-origin requests — the `host.pickDirectory` privileged set.

 ## Known Limitations and Deferred Work
 
+- **Forwarded Remote events are parasitic on this legacy frame union** — `host/remote-event` lives in `HostFrame` so the delivery path could reuse the existing host stream instead of opening a third downlink, which makes it read as if this package owned the Remote event contract. It does not: the allowlist is `dsh-api-remotes`' and the consumer verb is `ctx.remote.$on`. When the host stream moves off this package, the frame moves with it and the consumer contract is unaffected ([rationale](../../../.agents/notes/implemented/architecture/2026-08-10-remote-event-delivery.md)).
 - **Pending-interaction state is host-side** — the wire uses POST `/api/respond` plus `RpcReceipt`; the table in `src/api-proxy.ts` handles questions only and has no approval entries.
 - **Reserved seams stay out of `RpcMethodMap`** — `prompt.mode: 'inject'`, `task.list`, and a describe `hostInstanceId` are documented reservations; model discovery uses `llm.models`. An unknown method fails loud at envelope parse rather than getting a not-implemented code.
 - **No protocol version field** — client and host ship together; `host.describe` gains a version negotiation field only when an independently released client exists.

 - **Bound storage identity.** Lookup requires one matching session directory across the readable project directories, then verifies that the header id equals the requested id and that the header's id/cwd derive the selected transcript path. Listing applies the same path check and rejects duplicate ids. Identity failures occur before repair or append.
 - **Lazy materialization.** `create(meta)` writes nothing; on the first `append`, the backend writes and `fsync`s the encoded header and first batch in a temporary file. POSIX publishes it without overwrite via a hard link and `fsync`s the parent directory. Windows publishes it without overwrite via `MoveFileExW(..., MOVEFILE_WRITE_THROUGH)` and creates missing directories through the same write-through pattern. A created-but-never-appended session leaves nothing on disk and is absent from `list`.
 - **Append-only.** Flushed events are never rewritten. Subsequent raw batches append lines; compressed batches append one frame. Both paths `fsync`, and a caught write or sync failure rolls the file back to its prior byte length.
-- **Crash recovery — preserve valid tail work.** `load` validates every complete compressed frame and scans their decompressed JSONL. If the last frame is structurally incomplete, the reader keeps its complete decoded records, truncates from that frame's start, and re-encodes those records with the synthetic tool, step, and turn closers required by the shared [persistence contract](../../../.agents/notes/implemented/architecture/2026-06-14-session-persistence.md). Raw mode truncates from its first incomplete line. A checksum/decompression failure in a complete frame, or a defect at or before the last committed `turn/end`, is corruption and rejects.

Raw mode truncates from its first incomplete line. An existing compressed artifact with no complete header frame, a checksum/decompression failure in a complete frame, or a defect at or before the last committed `turn/end` is corruption and rejects.
 - **Non-mutating inspection.** `inspect()` returns an immutable balanced logical view and may synthesize recovery closers in memory, without truncating an incomplete tail or changing the lightweight revision.
 - **Contiguous-seq.** `append` rejects a batch whose first `seq` does not continue the stored log, and rejects non-JSON-serializable `event.data` naming the offending event type.
 - **Lightweight revisions.** `listSnapshots(signal?)` identifies a log by its device, inode, size, and nanosecond timestamps, avoiding a full-log parse while changing after append, repair, replacement, or store changes. A full-prefix read requires the same identity before and after reading the bytes, and `readStoredRevision()` uses that identity to validate retained preparations without loading the log. Snapshot listing forwards the exact signal through artifact discovery and checks cancellation around every `stat`; because filesystem `stat` is not interruptible, cancellation waits for the active call to settle, then rejects without starting another.

 `settings/document-updated (ns, revision)` fires whenever the RAW user section changes, whether or not the resolved value did. Configuration surfaces need this one: storing an override equal to the composition base leaves the resolved value alone but changes what the document says (the field is now overridden, not inherited) and moves the revision every open editor is holding. Listener containment matches `settings/updated`.
 
+Both declarations live in the client-safe `./types` subpath export, together with the `SettingsNamespace` and `SettingsUpdateSource` types their signatures name; the package root re-exports those types. A consumer outside the Host compilation face therefore reads the very signature the Host emits instead of restating it.

 ## Model Experience
 
 Indirectly, through consumer plugins that resolve model-affecting values (for example a default model route) from their namespaces; each consumer's own surface documents the effect.

 `settings/document-updated (ns, revision)` 在**原始**用户分节发生变化时触发，无论解析值是否随之改变。配置界面需要的是这一个：存入一个与组合 `base` 相同的覆盖值不会改变解析值，却改变了文档的说法（该字段从继承变成了覆盖），也推进了每个已打开编辑器所持有的 revision。监听器的收容方式与 `settings/updated` 相同。
 
+两条声明都住在 client-safe 的 `./types` 子路径出口，与其签名点名的 `SettingsNamespace`、`SettingsUpdateSource` 类型同处一处；包根继续 re-export 这些类型。于是 Host 编译面之外的消费方读到的正是 Host 发射的那一份签名，而不必再写一遍。

 ## 模型体验
 
 间接生效：消费插件从各自 namespace 解析影响模型的值（例如默认模型路由）；效果由各消费者自己的文档描述。

+The Host assembly extends `TypeRTRemoteEventSelection` with the Host events it forwards to consumers, which narrows the `ctx.remote.$on` key face; `TypeRTForwardableEvent` states the shapes a one-way delivery can carry at all, excluding Scope-bound and answered events. `TypeRTClientRemote` carries both roles of that surface: consumers subscribe through `$on`, and the Client half owning the host frame sink hands frames over through `$dispatch`.
+
 Lookup and Context packages own both sides of their contract: declaration merging supplies the static association, while runtime providers register identity resolution with `ctx.typert`. A lookup or Host Context provider supplies the stable declaration and default resolver, while Host composition may separately configure a synchronous or asynchronous resolver; policy rejections may use `TypeRTLookupFailure` to carry a failure value owned by the boundary adapter. Strict codecs carry generated schemas; `src-json` codecs identify the weaker source-launch path.

A non-`completed` stop reason maps to an `isError` result reporting the reason—never partial output as success; a parse/meta failure thrown synchronously by `start()` becomes an `isError` the model can correct from.

+For a root transport execution (`exec.parent` absent), the tool also projects the run into the calling Agent's Session: run-start after `start()` returns, matching member starts and endings filtered by `run.id`, then run-end only after `run.result` is available and `dispose()` has reached quiescence. Nested transport calls execute normally but write no workflow record. The first failed Session append disables later recording for that run, emits one warning, and leaves either no record or a legal continuous prefix without changing the tool result or cleanup.

 - **父级轮次会阻塞到整个工作流结算**：没有后台启动/轮询接口，取消会把局部输出作为错误丢弃。
 - **`args` 必须是对象，Native 结果文本有界**：调用方把顶层数组/标量包装到字段中；规范工作流结果保持完整，超过 `maxResultChars` 的 JSON 会在面向模型的投影中截断，而不是存储在检索句柄背后。
 - **每次工具注册的工作流策略固定**：提供方选择、上限和工具名称属于部署配置，不是模型调用参数。
+- **持久记录只覆盖顶层且只供观察**：嵌套 Code Mode dispatch 不记录；记录故障会刻意退化为不完整前缀，而不改变执行。

 `@deepseek-ai/dsh-workflow-workerthread` is the current engine and `@deepseek-ai/dsh-tool-workflow` is the model-facing consumer. A future process or sandbox engine can replace the implementation without changing the tool.
 
+The package root is the Host face. The browser-safe `@deepseek-ai/dsh-workflow/types` subpath contains run identities, metadata, results, and observe-only lifecycle payloads without importing `Agent`, Cordis services, or Host context declarations; Host-only `WorkflowStartRequest` and `WorkflowRun` live behind the package root.
+
 ## Service and run contract
 
 `WorkflowService.start(request): WorkflowRun` validates enough synchronously to reject a malformed meta block, unparseable script, unavailable provider route, or unsupported per-run limit before a run exists. Once returned, `WorkflowRun.result` never rejects: execution failures resolve with `stopReason: 'error'`, and cancellation resolves with `cancelled` within the engine's bounded grace.

 `@deepseek-ai/dsh-workflow-workerthread` 是当前引擎，`@deepseek-ai/dsh-tool-workflow` 是面向模型的消费方。未来的进程或沙箱引擎可以替换实现，而无需更改工具。
 
+包根是 Host face。浏览器安全的 `@deepseek-ai/dsh-workflow/types` 子路径包含运行身份、元数据、结果和仅供观察的生命周期 payload，不导入 `Agent`、Cordis service 或 Host Context 声明；Host 专用的 `WorkflowStartRequest` 与 `WorkflowRun` 只从包根提供。

 ## 服务与运行约定
 
 `WorkflowService.start(request): WorkflowRun` 会同步完成足够多的校验，在运行创建前拒绝格式错误的 meta 块、无法解析的脚本、不可用的提供方路由或不受支持的单次运行限制。返回后，`WorkflowRun.result` 绝不拒绝：执行失败以 `stopReason: 'error'` 兑现，取消则在引擎有限的宽限时间内以 `cancelled` 兑现。

-        "content": "# Development guide\n\nEnglish | [中文](development.zh.md)\n\nThe setup tutorial takes a new contributor from prerequisites to a checked checkout. The contributor reference that follows covers repository layout, daily workflow, and CI organization. Design rationale and implementation details belong to the linked Agent Notes and scripts.\n\n## Setup tutorial\n\n### Prerequisites\n\n- Node.js supports 22.19+ and 24+. CI covers 22.19, 24, and 26; see the [Node engine floor Agent Note](../.agents/notes/implemented/process/2026-07-06-node-engine-floor.md).\n- Corepack-enabled pnpm. The repo pins `pnpm@11.7.0` in `package.json`; run `corepack enable` if `pnpm --version` does not resolve through Corepack.\n- Git 2.26 or newer; hook setup enables Git's worktree-specific configuration extension.\n- Optional: a DeepSeek API key for the Web, headless, and ACP automation demos and real-API e2e tests.\n\n### First-time setup\n\nInstall dependencies from the repo root:\n\n```sh\npnpm install\n```\n\nThe install also configures worktree-local Lefthook hooks and the `dsh-translation-pairing` Git merge driver through `scripts/install-lefthook.mjs`. The [worktree-local hooks Agent Note](../.agents/notes/implemented/process/2026-07-27-worktree-local-lefthook.md) owns the hook-path safety contract; the [automatic pairing merges Agent Note](../.agents/notes/implemented/process/2026-08-08-automatic-translation-pairing-merges.md) owns the merge driver.\n\nIf either integration is missing because dependencies were restored from cache or `postinstall` was skipped, install them manually:\n\n```sh\nnode scripts/install-lefthook.mjs\n```\n\nIf the wrapper rejects existing Git configuration or reports a stale lock, follow its diagnostic and the linked Agent Note rather than editing worktree metadata speculatively. After moving a checkout, rerun the wrapper to regenerate the owned path.\n\nRun typecheck once after a fresh clone:\n\n```sh\npnpm run typecheck\n```\n\nSetup is complete when `pnpm run typecheck` exits successfully.\n\n## Contributor reference\n\n### TypeScript project layout\n\nThe repository uses isolated Host and Client aggregates. An ordinary package is registered in exactly one aggregate: Host packages in `tsconfig.host.json` and Client packages in `tsconfig.client.json`.\n\n| File | Role | Forms a program? |\n|---|---|---|\n| `tsconfig.json` | Solution root: `extends` base, `files: []`, and references to the two aggregates. It is the tsserver discovery entry and the entry for explicitly running the complete Project Reference graph; through the inherited `paths`, it is also the resolution config for tsx running `examples/` and `scripts/`. | No |\n| `tsconfig.host.json` | Host aggregate: Host packages, examples, tests, scripts, website, and the exceptional Host project of `api/remotes`. | Yes |\n| `tsconfig.client.json` | Client aggregate: `packages/client/*` packages and their tests, `apps/web`, and the exceptional Client project of `api/remotes`. | Yes |\n| `tsconfig.base.json` | Shared compilerOptions and the source `paths` map. Also the resolution facade the vitest configs point vite-tsconfig-paths at: it has no `include`, so its `paths` apply to every importer. | No |\n| `tsconfig.base.client.json` | Browser compiler settings (`jsx`, DOM libs, `types: []`) extended by the Client aggregate and every `packages/client/*` package. | No |\n\nHost and Client stay two aggregate programs because both sides declaration-merge the cordis `Context` interface under the same keys with different services; one program seeing both merges reports a collision. The collision exists only inside a `ts.Program` — module resolution never triggers it — which is why the solution may reference both aggregates and one paths facade may span both sides. Three disciplines follow:\n\n- `tsconfig.base.json` never gains `include` or `files`: they would leak into every extending package project and narrow the facade's match-all scope.\n- A script that builds a repo-wide `ts.Program` seeds `tsconfig.host.json` or `tsconfig.client.json` explicitly — never the root solution, because flattening both aggregates into one program collides the `Context` merges.\n- A new package is registered in exactly one aggregate. Having both a Node loader entry and a browser entry is not a reason to split a package; an ordinary Client plugin produces both runtime artifacts during the Client build phase.\n\n`api/remotes` is the repository's only package with split Host and Client tsconfigs. Its Host entry must participate in the Host TypeRT graph, while its Client entry imports `/remote` declarations that Host tsdown must generate first. The package-root `tsconfig.json` is therefore only a solution, and the two aggregates and direct consumers reference `tsconfig.host.json` or `tsconfig.client.json` respectively. The workspace `constraints` gate walks the reachable Project Reference graph and checks each referencing project's own compiler face: a single-config target remains valid from either face, while a split target must name the matching leaf rather than its solution root or opposite leaf. Do not copy this structure to other packages; the [`api-remotes` README](../packages/api/remotes/README.md) explains the Host/Client split and build order.\n\nThe root build follows the generated dependency order:\n\n```sh\ntsc -b tsconfig.host.json\ntsdown --env.DSH_BUILD_FACE host\ntsc -b tsconfig.client.json\ntsdown --env.DSH_BUILD_FACE client\npnpm run build:web\n```\n\nBoth tsdown passes use the same complete workspace match. They neither scan build artifacts to discover Client packages nor maintain a Host/Client package filter list. Package-local tsdown configs select entries for the current phase through `DSH_BUILD_FACE`: an ordinary Client plugin produces both its Node loader and browser bundle during the Client phase; `api-remotes` uses `hostPhase: true` to produce its Host entry early and only its browser bundle during the Client phase. Tsdown consumes only the JavaScript emitted to `lib/types` by the preceding tsc phase.\n\nTypeRT runs only during Host tsdown, seeded by `tsconfig.host.json`. It analyzes Host types and generates both Host reflection artifacts and the Host-for-Client Remote projection; Client tsdown does not start TypeRT. Consequently, `pnpm run typecheck` runs the complete Host lib phase before Client tsc, while `pnpm run build` continues through Client tsdown and the Web build. The [API Remotes generated-contract build note](../.agents/notes/implemented/process/2026-08-08-api-remotes-generated-contract-build.md) records this ordering decision.\n\nStatic analysis and tests resolve workspace imports through the base `paths` map to `src` and must pass on a clean tree; gates that consume built `lib/` output declare that dependency explicitly. Generated Host-for-Client Remote declarations are the deliberate exception: the public `typecheck`, `lint`, and `doc-typecheck` commands generate them first, while internal `*:contracts-ready` scripts assume that an invoking public command or scheduler gate already depends on the TypeRT contract-generation pass or the complete build. See the [solution-root note](../.agents/notes/implemented/process/2026-07-22-tsconfig-solution-root-two-aggregates.md) for the two-aggregate setup, the [ts-build-config note](../.agents/notes/implemented/process/2026-06-17-ts-build-config.md) for tsc-first emit ownership, and the [TypeRT Remote note](../.agents/notes/implemented/architecture/2026-08-02-typert-remote-method-calls.md) for the gate-preparation contract.\n\nBusiness services declare callable methods on the Host with `@Remote` or `@RemoteScope`; the Host build generates Host-for-Client types and runtime contributions, and the Client's `api-remotes` composition loads those contributions under `ctx.remote` and scoped `agentCtx.remote` namespaces. See [API Gateway](api-gateway.md) for the generated artifacts on both sides, their assembly relationships, the SRC development fallback, and the Web build order.\n\nIf a relevant local check consumes built package output, build once first:\n\n```sh\npnpm run build\n```\n\n`pnpm run hygiene` includes `publint`, which validates package entrypoints against the built `lib/*.js` files, and `verify-node-next-types`, which validates built declarations against a temporary NodeNext consumer. A fresh worktree has no bundled JS or declarations until `pnpm run build` runs; ordinary commits and pushes do not require that build unless their selected checks consume it.\n\n### Environment variables\n\nThe real DeepSeek adapter and key-backed agent demos read credentials from the environment or from a gitignored `.env` at the repo root:\n\n```sh\nDEEPSEEK_API_KEY=sk-...\nDEEPSEEK_BASE_URL=https://... # optional\n```\n\n`DEEPSEEK_BASE_URL` is optional and defaults to the public API. Never commit real credentials. The real-API e2e suites self-skip when `DEEPSEEK_API_KEY` is not set.\n\n### Git integrations\n\nThe pairing merge driver derives a conflicted `.i18n.yaml` record from the confirmed ancestor, current, and other owner blobs when both language files use Git's default text strategy and merge cleanly. It fails closed on owner conflicts, non-text merge configuration, or invalid records; after an already-stopped merge, run `pnpm run resolve-translation-pairing-conflicts`, which stages every safe pairing record and exits unsuccessfully if other pairing conflicts still need manual work. See the [bilingual documentation contract](i18n/README.md#the-pairing-contract) for the exact files and states the driver accepts.\n\nThe installer probes the exact Node/tsx driver entrypoint before publishing its worktree configuration. If that runtime later becomes unavailable, the Node-independent launcher writes Git's ordinary text result, leaves the sidecar unresolved, and prints the recovery path; restore dependencies and run `pnpm run resolve-translation-pairing-conflicts`, or run `git merge --abort`. If `pre-merge-commit` rejects an otherwise clean merge, Git leaves the complete result staged without a commit; repair the failure and run `git commit`, or abort. The [automatic pairing merges Agent Note](../.agents/notes/implemented/process/2026-08-08-automatic-translation-pairing-merges.md#failure-contract) owns the exact index and `MERGE_HEAD` states.\n\nlefthook is configured in `lefthook.yml` as a fast local checkpoint:\n\n- `pre-commit` verifies staged pairing records against the staged owner blobs, validates staged files with the project-free `.oxlintrc.staged.json` profile and applies Oxlint fixes with one bounded retry, regenerates `THIRD_PARTY_NOTICES.md` when a staged file is one of its inputs, checks the staged diff for whitespace errors, and runs the vendor manifest guard.\n- `pre-merge-commit` performs the same index-backed pairing check before Git creates an automatic merge commit.\n- `pre-push` runs `pnpm run typecheck`, which completes the Host lib phase, including generated TypeRT contracts, before the Client TypeScript check.\n\nThe vendor manifest guard checks that changes under `vendor/*/src` are staged with the matching `vendor/README.md` manifest update. See `vendor/README.md` before editing vendored code.\n\nApart from the scoped staged-record verification, the hooks intentionally do not run tests, snapshots, documentation checks, builds, or hygiene. Contributors run the [checks relevant to the changed behavior](../AGENTS.md#run-relevant-checks-locally) once; CI owns exhaustive coverage, built-artifact smokes, and the Node 22.19, 24, and 26 compatibility matrix.\n\nContributors can opt into the comprehensive local gate set with `pnpm run check:all`. The command is independent of the Git hooks and is not an agent instruction.\n\n### CI gates\n\nThe keyless [CI workflow](../.github/workflows/ci.yml) groups independent gates into broad lanes and runs a smaller compatibility signal across supported Node versions. Artifact consumers wait for one build within their lane. The separate real-API workflow runs `pnpm run test:e2e` with its configured worker bound. See [scripts/run-gates.ts](../scripts/run-gates.ts) and the workflow files for the current gate and job inventory.\n\n### Daily commands\n\nThe root [contributor instructions](../AGENTS.md#commands) summarize common commands, while [`package.json`](../package.json) and [scripts/run-gates.ts](../scripts/run-gates.ts) own the current script and gate inventories. Select the smallest checks that cover the changed surface. Documentation changes use `pnpm run doc-sync`; package-public behavior changes also update the owning README or JSDoc, and built-artifact checks require `pnpm run build` first.\n\n### Demos\n\nThe one-shot Headless coding agent needs `DEEPSEEK_API_KEY` in the environment or repo-root `.env`:\n\n```sh\npnpm dsh --profile headless \"summarize this workspace\"\n```\n\nThe self-referential cordis demo can inspect and modify its live plugin runtime and needs the same credentials (`web` by default, or `acp`):\n\n```sh\npnpm run demo:cordis\n```\n\nThe ACP automation server exposes fresh agent sessions over JSON-RPC stdio and also needs `DEEPSEEK_API_KEY`:\n\n```sh\npnpm run demo:acp\n```\n\n### TODO markers\n\nUse one of three comment tags to flag known issues in the code, ordered by urgency:\n\n- `FIXME` — an issue that should block a new release. A release should not ship with an open `FIXME` unless reviewers explicitly agree the change can be merged anyway.\n- `TODO` — an issue that should be fixed soon, once we have the resources.\n- `XXX` — an issue that we may fix someday; lowest priority, no commitment.\n\nPick the tag that matches the urgency so anyone scanning the code can tell a release blocker from a someday-maybe.\n\n### Documenting types verbatim (`ts type-equiv`)\n\nThe [subsystems](subsystems/README.md) pages paste source-equivalent declarations together with their original JSDoc so a reader sees the exact type definition and source contract. To keep a paste from drifting when source changes, fence it as ` ```ts type-equiv ` (instead of ` ```ts `) and register it in `scripts/type-equiv.manifest.json` with the source file and symbol it mirrors:\n\n```json\n{ \"doc\": \"docs/subsystems/session.md\", \"symbol\": \"SessionEvent\", \"source\": \"packages/core/session/src/types.ts\" }\n```\n\n`pnpm run verify-type-equiv` (part of `doc-sync`) then extracts that symbol's declaration and attached JSDoc from source via the TypeScript parser and asserts the block matches both. For a class whose implementation bodies do not belong in the catalog, use ` ```ts public-api ` and set `\"projection\": \"public-api\"`; the checked projection retains the public fields, constructor, accessors, methods, and original class/member JSDoc while omitting bodies and private or protected members. Comparison ignores whitespace and non-JSDoc comments but requires every original JSDoc comment, including member documentation, so readers see the source contract beside the exact type definition. The gate enforces a 1:1 correspondence by document, symbol, and projection between primary blocks and manifest entries; a paired `.zh.md` block reuses its unsuffixed sibling's entry only when the whole tracked fence sequence is byte-identical and ordered identically. `doc-typecheck` applies the same derivative rule to compilable fences, while skipping both source-equivalence fence kinds from compilation and its opt-out ratio. When you change a documented declaration or its JSDoc, the gate fails until you update the paste; when you add or remove a primary block, update the manifest in the same change.\n"
+        "content": "# Development guide\n\nEnglish | [中文](development.zh.md)\n\nThe setup tutorial takes a new contributor from prerequisites to a checked checkout. The contributor reference that follows covers repository layout, daily workflow, and CI organization. Design rationale and implementation details belong to the linked Agent Notes and scripts.\n\n## Setup tutorial\n\n### Prerequisites\n\n- Node.js supports 22.19+ and 24+. CI covers 22.19, 24, and 26; see the [Node engine floor Agent Note](../.agents/notes/implemented/process/2026-07-06-node-engine-floor.md).\n- Corepack-enabled pnpm. The repo pins `pnpm@11.7.0` in `package.json`; run `corepack enable` if `pnpm --version` does not resolve through Corepack.\n- Git 2.26 or newer; hook setup enables Git's worktree-specific configuration extension.\n- Optional: a DeepSeek API key for the Web, headless, and ACP automation demos and real-API e2e tests.\n\n### First-time setup\n\nInstall dependencies from the repo root:\n\n```sh\npnpm install\n```\n\nThe install also configures worktree-local Lefthook hooks and the `dsh-translation-pairing` Git merge driver through `scripts/install-lefthook.mjs`. The [worktree-local hooks Agent Note](../.agents/notes/implemented/process/2026-07-27-worktree-local-lefthook.md) owns the hook-path safety contract; the [automatic pairing merges Agent Note](../.agents/notes/implemented/process/2026-08-08-automatic-translation-pairing-merges.md) owns the merge driver.\n\nIf either integration is missing because dependencies were restored from cache or `postinstall` was skipped, install them manually:\n\n```sh\nnode scripts/install-lefthook.mjs\n```\n\nIf the wrapper rejects existing Git configuration or reports a stale lock, follow its diagnostic and the linked Agent Note rather than editing worktree metadata speculatively. After moving a checkout, rerun the wrapper to regenerate the owned path.\n\nRun typecheck once after a fresh clone:\n\n```sh\npnpm run typecheck\n```\n\nSetup is complete when `pnpm run typecheck` exits successfully.\n\n## Contributor reference\n\n### TypeScript project layout\n\nThe repository uses isolated Host and Client aggregates. An ordinary package is registered in exactly one aggregate: Host packages in `tsconfig.host.json` and Client packages in `tsconfig.client.json`.\n\n| File | Role | Forms a program? |\n|---|---|---|\n| `tsconfig.json` | Solution root: `extends` base, `files: []`, and references to the two aggregates. It is the tsserver discovery entry and the entry for explicitly running the complete Project Reference graph; through the inherited `paths`, it is also the resolution config for tsx running `examples/` and `scripts/`. | No |\n| `tsconfig.host.json` | Host aggregate: Host packages, examples, tests, scripts, website, and the exceptional Host project of `api/remotes`. | Yes |\n| `tsconfig.client.json` | Client aggregate: `packages/client/*` packages and their tests, `apps/web`, and the exceptional Client project of `api/remotes`. | Yes |\n| `tsconfig.base.json` | Shared compilerOptions and the source `paths` map. Also the resolution facade the vitest configs point vite-tsconfig-paths at: it has no `include`, so its `paths` apply to every importer. | No |\n| `tsconfig.base.client.json` | Browser compiler settings (`jsx`, DOM libs, `types: []`) extended by the Client aggregate and every `packages/client/*` package. | No |\n\nHost and Client stay two aggregate programs because both sides declaration-merge the cordis `Context` interface under the same keys with different services; one program seeing both merges reports a collision. The collision exists only inside a `ts.Program` — module resolution never triggers it — which is why the solution may reference both aggregates and one paths facade may span both sides. Three disciplines follow:\n\n- `tsconfig.base.json` never gains `include` or `files`: they would leak into every extending package project and narrow the facade's match-all scope.\n- A script that builds a repo-wide `ts.Program` seeds `tsconfig.host.json` or `tsconfig.client.json` explicitly — never the root solution, because flattening both aggregates into one program collides the `Context` merges.\n- A new package is registered in exactly one aggregate. Having both a Node loader entry and a browser entry is not a reason to split a package; an ordinary Client plugin produces both runtime artifacts during the Client build phase.\n\n`api/remotes` is the repository's only package with split Host and Client tsconfigs. Its Host entry must participate in the Host TypeRT graph, while its Client entry imports `/remote` declarations that Host tsdown must generate first. The package-root `tsconfig.json` is therefore only a solution, and the two aggregates and direct consumers reference `tsconfig.host.json` or `tsconfig.client.json` respectively. The workspace `constraints` gate walks the reachable Project Reference graph and checks each referencing project's own compiler face: a single-config target remains valid from either face, while a split target must name the matching leaf rather than its solution root or opposite leaf; it discovers split packages from the presence of both leaf configs, so a new split joins the gate automatically. Do not copy this structure to other packages; the [`api-remotes` README](../packages/api/remotes/README.md) explains the Host/Client split and build order.\n\nThe root build follows the generated dependency order:\n\n```sh\ntsc -b tsconfig.host.json\ntsdown --env.DSH_BUILD_FACE host\ntsc -b tsconfig.client.json\ntsdown --env.DSH_BUILD_FACE client\npnpm run build:web\n```\n\nBoth tsdown passes use the same complete workspace match. They neither scan build artifacts to discover Client packages nor maintain a Host/Client package filter list. Package-local tsdown configs select entries for the current phase through `DSH_BUILD_FACE`: an ordinary Client plugin produces both its Node loader and browser bundle during the Client phase; `api-remotes` uses `hostPhase: true` to produce its Host entry early and only its browser bundle during the Client phase. Tsdown consumes only the JavaScript emitted to `lib/types` by the preceding tsc phase.\n\nTypeRT runs only during Host tsdown, seeded by `tsconfig.host.json`. It analyzes Host types and generates both Host reflection artifacts and the Host-for-Client Remote projection; Client tsdown does not start TypeRT. Consequently, `pnpm run typecheck` runs the complete Host lib phase before Client tsc, while `pnpm run build` continues through Client tsdown and the Web build. The [API Remotes generated-contract build note](../.agents/notes/implemented/process/2026-08-08-api-remotes-generated-contract-build.md) records this ordering decision.\n\nStatic analysis and tests resolve workspace imports through the base `paths` map to `src` and must pass on a clean tree; gates that consume built `lib/` output declare that dependency explicitly. Generated Host-for-Client Remote declarations are the deliberate exception: the public `typecheck`, `lint`, and `doc-typecheck` commands generate them first, while internal `*:contracts-ready` scripts assume that an invoking public command or scheduler gate already depends on the TypeRT contract-generation pass or the complete build. See the [solution-root note](../.agents/notes/implemented/process/2026-07-22-tsconfig-solution-root-two-aggregates.md) for the two-aggregate setup, the [ts-build-config note](../.agents/notes/implemented/process/2026-06-17-ts-build-config.md) for tsc-first emit ownership, and the [TypeRT Remote note](../.agents/notes/implemented/architecture/2026-08-02-typert-remote-method-calls.md) for the gate-preparation contract.\n\nBusiness services declare callable methods on the Host with `@Remote` or `@RemoteScope`; the Host build generates Host-for-Client types and runtime contributions, and the Client's `api-remotes` composition loads those contributions under `ctx.remote` and scoped `agentCtx.remote` namespaces. See [API Gateway](api-gateway.md) for the generated artifacts on both sides, their assembly relationships, the SRC development fallback, and the Web build order.\n\nIf a relevant local check consumes built package output, build once first:\n\n```sh\npnpm run build\n```\n\n`pnpm run hygiene` includes `publint`, which validates package entrypoints against the built `lib/*.js` files, and `verify-node-next-types`, which validates built declarations against a temporary NodeNext consumer. A fresh worktree has no bundled JS or declarations until `pnpm run build` runs; ordinary commits and pushes do not require that build unless their selected checks consume it.\n\n### Environment variables\n\nThe real DeepSeek adapter and key-backed agent demos read credentials from the environment or from a gitignored `.env` at the repo root:\n\n```sh\nDEEPSEEK_API_KEY=sk-...\nDEEPSEEK_BASE_URL=https://... # optional\n```\n\n`DEEPSEEK_BASE_URL` is optional and defaults to the public API. Never commit real credentials. The real-API e2e suites self-skip when `DEEPSEEK_API_KEY` is not set.\n\n### Git integrations\n\nThe pairing merge driver derives a conflicted `.i18n.yaml` record from the confirmed ancestor, current, and other owner blobs when both language files use Git's default text strategy and merge cleanly. It fails closed on owner conflicts, non-text merge configuration, or invalid records; after an already-stopped merge, run `pnpm run resolve-translation-pairing-conflicts`, which stages every safe pairing record and exits unsuccessfully if other pairing conflicts still need manual work. See the [bilingual documentation contract](i18n/README.md#the-pairing-contract) for the exact files and states the driver accepts.\n\nThe installer probes the exact Node/tsx driver entrypoint before publishing its worktree configuration. If that runtime later becomes unavailable, the Node-independent launcher writes Git's ordinary text result, leaves the sidecar unresolved, and prints the recovery path; restore dependencies and run `pnpm run resolve-translation-pairing-conflicts`, or run `git merge --abort`. If `pre-merge-commit` rejects an otherwise clean merge, Git leaves the complete result staged without a commit; repair the failure and run `git commit`, or abort. The [automatic pairing merges Agent Note](../.agents/notes/implemented/process/2026-08-08-automatic-translation-pairing-merges.md#failure-contract) owns the exact index and `MERGE_HEAD` states.\n\nlefthook is configured in `lefthook.yml` as a fast local checkpoint:\n\n- `pre-commit` verifies staged pairing records against the staged owner blobs, validates staged files with the project-free `.oxlintrc.staged.json` profile and applies Oxlint fixes with one bounded retry, regenerates `THIRD_PARTY_NOTICES.md` when a staged file is one of its inputs, checks the staged diff for whitespace errors, and runs the vendor manifest guard.\n- `pre-merge-commit` performs the same index-backed pairing check before Git creates an automatic merge commit.\n- `pre-push` runs `pnpm run typecheck`, which completes the Host lib phase, including generated TypeRT contracts, before the Client TypeScript check.\n\nThe vendor manifest guard checks that changes under `vendor/*/src` are staged with the matching `vendor/README.md` manifest update. See `vendor/README.md` before editing vendored code.\n\nApart from the scoped staged-record verification, the hooks intentionally do not run tests, snapshots, documentation checks, builds, or hygiene. Contributors run the [checks relevant to the changed behavior](../AGENTS.md#run-relevant-checks-locally) once; CI owns exhaustive coverage, built-artifact smokes, and the Node 22.19, 24, and 26 compatibility matrix.\n\nContributors can opt into the comprehensive local gate set with `pnpm run check:all`. The command is independent of the Git hooks and is not an agent instruction.\n\n### CI gates\n\nThe keyless [CI workflow](../.github/workflows/ci.yml) groups independent gates into broad lanes and runs a smaller compatibility signal across supported Node versions. Artifact consumers wait for one build within their lane. The separate real-API workflow runs `pnpm run test:e2e` with its configured worker bound. See [scripts/run-gates.ts](../scripts/run-gates.ts) and the workflow files for the current gate and job inventory.\n\n### Daily commands\n\nThe root [contributor instructions](../AGENTS.md#commands) summarize common commands, while [`package.json`](../package.json) and [scripts/run-gates.ts](../scripts/run-gates.ts) own the current script and gate inventories. Select the smallest checks that cover the changed surface. Documentation changes use `pnpm run doc-sync`; package-public behavior changes also update the owning README or JSDoc, and built-artifact checks require `pnpm run build` first.\n\n### Demos\n\nThe one-shot Headless coding agent needs `DEEPSEEK_API_KEY` in the environment or repo-root `.env`:\n\n```sh\npnpm dsh --profile headless \"summarize this workspace\"\n```\n\nThe self-referential cordis demo can inspect and modify its live plugin runtime and needs the same credentials (`web` by default, or `acp`):\n\n```sh\npnpm run demo:cordis\n```\n\nThe ACP automation server exposes fresh agent sessions over JSON-RPC stdio and also needs `DEEPSEEK_API_KEY`:\n\n```sh\npnpm run demo:acp\n```\n\n### TODO markers\n\nUse one of three comment tags to flag known issues in the code, ordered by urgency:\n\n- `FIXME` — an issue that should block a new release. A release should not ship with an open `FIXME` unless reviewers explicitly agree the change can be merged anyway.\n- `TODO` — an issue that should be fixed soon, once we have the resources.\n- `XXX` — an issue that we may fix someday; lowest priority, no commitment.\n\nPick the tag that matches the urgency so anyone scanning the code can tell a release blocker from a someday-maybe.\n\n### Documenting types verbatim (`ts type-equiv`)\n\nThe [subsystems](subsystems/README.md) pages paste source-equivalent declarations together with their original JSDoc so a reader sees the exact type definition and source contract.

For a class whose implementation bodies do not belong in the catalog, use ` ```ts public-api ` and set `\"projection\": \"public-api\"`; the checked projection retains the public fields, constructor, accessors, methods, and original class/member JSDoc while omitting bodies and private or protected members.

与 24+。CI 覆盖 22.19、24 和 26；见 [Node 引擎下限 Agent Note](../.agents/notes/implemented/process/2026-07-06-node-engine-floor.md)。\n- 启用了 Corepack 的 pnpm。仓库在 `package.json` 中固定使用 `pnpm@11.7.0`；如果 `pnpm --version` 无法通过 Corepack 解析，请先运行 `corepack enable`。\n- Git 2.26 或更高版本；钩子设置会启用 Git 的 worktree 专属配置扩展。\n- 可选：一个 DeepSeek API key，用于 Web、headless 和 ACP（Agent Client Protocol）自动化 agent（智能体）演示以及真实 API 的 e2e 测试。\n\n### 首次搭建\n\n在仓库根目录安装依赖：\n\n```sh\npnpm install\n```\n\n安装过程还会通过 `scripts/install-lefthook.mjs` 配置 worktree 本地的 Lefthook 钩子和 `dsh-translation-pairing` Git 合并驱动。[worktree 本地钩子 Agent Note](../.agents/notes/implemented/process/2026-07-27-worktree-local-lefthook.md) 负责钩子路径的安全约定；[自动配对合并 Agent Note](../.agents/notes/implemented/process/2026-08-08-automatic-translation-pairing-merges.md) 负责合并驱动。\n\n如果依赖是从缓存恢复或 `postinstall` 被跳过而导致任一集成缺失，请手动安装：\n\n```sh\nnode scripts/install-lefthook.mjs\n```\n\n如果包装脚本拒绝现有 Git 配置或报告陈旧锁，请遵循其诊断和所链接的 Agent Note，不要凭猜测编辑 worktree 元数据。移动检出目录后，请重新运行包装脚本以重新生成自有路径。\n\n新克隆后请先运行一次类型检查：\n\n```sh\npnpm run typecheck\n```\n\n`pnpm run typecheck` 成功退出即表示搭建完成。\n\n## 贡献者参考\n\n### TypeScript 项目布局\n\n仓库使用相互隔离的 Host 与 Client aggregate。普通 package 只登记进其中一个 aggregate；Host 包进入 `tsconfig.host.json`，Client 包进入 `tsconfig.client.json`。\n\n| 文件 | 角色 | 是否构成 program？ |\n|---|---|---|\n| `tsconfig.json` | solution 根：`extends` base、`files: []`、引用两个 aggregate。它是 tsserver 发现入口，也是显式执行整张 Project Reference 图时的入口；经继承的 `paths` 充当 tsx 运行 `examples/` 与 `scripts/` 时的解析配置。 | 否 |\n| `tsconfig.host.json` | Host aggregate：Host package、示例、测试、脚本和 website，以及 `api/remotes` 的 Host 特例 project。 | 是 |\n| `tsconfig.client.json` | Client aggregate：`packages/client/*` package 及其测试、`apps/web`，以及 `api/remotes` 的 Client 特例 project。 | 是 |\n| `tsconfig.base.json` | 共享 compilerOptions 与源码 `paths` 映射。同时是各 vitest 配置让 vite-tsconfig-paths 指向的解析门面：它没有 `include`，因此其 `paths` 适用于任何 importer。 | 否 |\n| `tsconfig.base.client.json` | 浏览器编译设置（`jsx`、DOM lib、`types: []`），由 Client aggregate 和每个 `packages/client/*` package extends。 | 否 |\n\nHost 与 Client 保持两个 aggregate program，是因为两侧在相同键下以不同服务对 cordis `Context` 接口做声明合并；单一 program 同时看到两份合并会报冲突。这种冲突只存在于 `ts.Program` 内部——模块解析永远不会触发它——所以 solution 可以同时引用两个 aggregate，一个 paths 门面也可以横跨两侧。由此推出三条纪律：\n\n- `tsconfig.base.json` 永不添加 `include` 或 `files`：它们会泄漏进每个 extends 它的包项目，并收窄门面的全匹配范围。\n- 构造全仓 `ts.Program` 的脚本显式种子 `tsconfig.host.json` 或 `tsconfig.client.json`——永不种子根 solution，因为把两个 aggregate 展平进一个 program 会撞上 `Context` 合并冲突。\n- 新 package 只登记进一个 aggregate。包同时具有 Node loader 入口和 browser 入口并不构成拆分理由；普通 Client plugin 的两份运行时产物都在 Client 构建阶段生成。\n\n`api/remotes` 是唯一拆分 Host/Client tsconfig 的仓库特例。它的 Host 入口必须进入 Host TypeRT 图，而 Client 入口导入 Host tsdown 才会生成的 `/remote` 声明，因此本包根 `tsconfig.json` 只作为 solution，两个 aggregate 和直接消费方分别引用 `tsconfig.host.json` 或 `tsconfig.client.json`。workspace `constraints` 门禁遍历可达的 Project Reference 图，并按各引用 project 自身的 compiler face 检查：只有单一配置的目标可由任一 face 引用，拆分配置的目标则必须引用匹配的 leaf，不得引用 solution 根或另一侧 leaf。不要把该结构推广到其他包；[`api-remotes` README](../packages/api/remotes/README.md) 说明 Host/Client 拆分与构建顺序。\n\n根构建按生成依赖排序：\n\n```sh\ntsc -b tsconfig.host.json\ntsdown --env.DSH_BUILD_FACE host\ntsc -b tsconfig.client.json\ntsdown --env.DSH_BUILD_FACE client\npnpm run build:web\n```\n\n两次 tsdown 都使用同一组完整 workspace 匹配，不扫描构建产物来发现 Client package，也不维护 Host/Client package 过滤表。包内 tsdown 配置根据 `DSH_BUILD_FACE` 决定当前阶段的入口：普通 Client plugin 在 Client 阶段同时生成 Node loader 与 browser bundle；`api-remotes` 通过 `hostPhase: true` 提前生成 Host 入口，再在 Client 阶段只生成 browser bundle。tsdown 只消费 `lib/types` 中由前置 tsc 发射的 JavaScript。\n\nTypeRT 只在 Host tsdown 中以 `tsconfig.host.json` 为种子运行。它分析 Host 类型并生成 Host 反射产物及 Host-for-Client Remote 投影；Client tsdown 不启动 TypeRT。`pnpm run typecheck` 因此先执行完整 Host lib 阶段，再运行 Client tsc；`pnpm run build` 继续执行 Client tsdown 和 Web 构建。该顺序的决策记录见 [API Remotes 生成约定构建 Note](../.agents/notes/implemented/process/2026-08-08-api-remotes-generated-contract-build.md)。\n\n静态分析和测试通过 base 的 `paths` 映射把工作区 import 解析到 `src`，且必须在干净树上通过；消费构建产物 `lib/` 的门禁显式声明该依赖。生成的 Host-for-Client Remote 声明是有意设置的例外：公共 `typecheck`、`lint` 和 `doc-typecheck` 命令会先生成这些声明，而内部 `*:contracts-ready` 脚本假定调用它的公共命令或调度器门禁已经依赖 TypeRT 约定生成阶段或完整构建。两个 aggregate 的设置见 [solution-root Note](../.agents/notes/implemented/process/2026-07-22-tsconfig-solution-root-two-aggregates.md)，tsc-first 发射职责见 [ts-build-config Note](../.agents/notes/implemented/process/2026-06-17-ts-build-config.md)，门禁准备约定见 [TypeRT Remote Agent Note](../.agents/notes/implemented/architecture/2026-08-02-typert-remote-method-calls.md)。\n\n业务 Service 在 Host 使用 `@Remote` 或 `@RemoteScope` 声明可调用方法；Host 构建生成 Host-for-Client 类型与运行时贡献，Client 的 `api-remotes` 组合加载这些贡献并挂到 `ctx.remote` 与作用域 `agentCtx.remote` namespace。两侧的生成产物、装配关系、SRC 开发回退和 Web 构建顺序见 [API Gateway](api-gateway.md)。\n\n如果相关的本地检查需要使用构建后的包产物，请先构建一次：\n\n```sh\npnpm run build\n```\n\n`pnpm run hygiene` 包含 `publint`（用构建出的 `lib/*.js` 文件校验 package 入口点）和 `verify-node-next-types`（用一个临时的 NodeNext 消费方校验构建出的声明文件）。新 worktree 在 `pnpm run build` 运行之前没有打包的 JS 和声明文件；普通提交和推送无需构建，除非所选检查会使用这些产物。\n\n### 环境变量\n\n真实的 DeepSeek 适配器和需要密钥的 agent 演示从环境变量或仓库根目录一个被 gitignore 的 `.env` 文件读取凭证：\n\n```sh\nDEEPSEEK_API_KEY=sk-...\nDEEPSEEK_BASE_URL=https://... # optional\n```\n\n`DEEPSEEK_BASE_URL` 可选，默认为公开 API。请勿提交真实凭证。未设置 `DEEPSEEK_API_KEY` 时，真实 API 的 e2e 套件会自动跳过。\n\n### Git 集成\n\n当两种语言的文件都使用 Git 默认文本策略且能干净合并时，配对合并驱动会根据已确认的祖先、当前和另一侧的配对文档 blob，推导出发生冲突的 `.i18n.yaml` 记录。配对文档发生冲突、存在非文本合并配置或记录无效时，它会拒绝处理并保留冲突；如果合并已经因冲突而停止，请运行 `pnpm run resolve-translation-pairing-conflicts`，该命令会暂存每份可安全生成的配对记录；如果其他配对冲突仍需手工处理，则以非零状态退出。[双语文档约定](i18n/README.md#the-pairing-contract)列出该驱动接受的确切文件和状态。\n\n安装脚本在发布 worktree 配置前，会探测确切的 Node/tsx 驱动入口点。如果该运行时之后变得不可用，不依赖 Node 的启动器会写入 Git 的普通文本合并结果、让伴随文件保持未解决状态，并打印恢复路径；请恢复依赖后运行 `pnpm run resolve-translation-pairing-conflicts`，或运行 `git merge --abort`。如果 `pre-merge-commit` 拒绝原本能干净完成的合并，Git 会把完整结果留在暂存区但不创建提交；请修复失败后运行 `git commit`，或中止合并。确切的索引与 `MERGE_HEAD` 状态由[自动配对合并 Agent Note](../.agents/notes/implemented/process/2026-08-08-automatic-translation-pairing-merges.md#failure-contract)负责记录。\n\nlefthook 在 `lefthook.yml` 中配置，作为快速的本地检查点：\n\n- `pre-commit` 对照暂存的配对文档 blob 校验暂存的配对记录，使用不加载项目的 `.oxlintrc.staged.json` 配置验证暂存文件，并通过一次有界重试应用 Oxlint 修复，在暂存文件属于 `THIRD_PARTY_NOTICES.md` 的输入时重新生成该文件，然后检查暂存 diff 中的空白错误，并运行 vendor manifest（元数据清单）守卫；\n- `pre-merge-commit` 在 Git 创建自动合并提交前执行同样以索引为准的配对检查；\n- `pre-push` 运行 `pnpm run typecheck`；该命令会先完成包含 TypeRT 约定生成的完整 Host lib 阶段，再运行 Client TypeScript 检查。\n\nvendor manifest 守卫检查 `vendor/*/src` 下的改动是否连同对应的 `vendor/README.md`

与 24+。CI 覆盖 22.19、24 和 26；见 [Node 引擎下限 Agent Note](../.agents/notes/implemented/process/2026-07-06-node-engine-floor.md)。\n- 启用了 Corepack 的 pnpm。仓库在 `package.json` 中固定使用 `pnpm@11.7.0`；如果 `pnpm --version` 无法通过 Corepack 解析，请先运行 `corepack enable`。\n- Git 2.26 或更高版本；钩子设置会启用 Git 的 worktree 专属配置扩展。\n- 可选：一个 DeepSeek API key，用于 Web、headless 和 ACP（Agent Client Protocol）自动化 agent（智能体）演示以及真实 API 的 e2e 测试。\n\n### 首次搭建\n\n在仓库根目录安装依赖：\n\n```sh\npnpm install\n```\n\n安装过程还会通过 `scripts/install-lefthook.mjs` 配置 worktree 本地的 Lefthook 钩子和 `dsh-translation-pairing` Git 合并驱动。[worktree 本地钩子 Agent Note](../.agents/notes/implemented/process/2026-07-27-worktree-local-lefthook.md) 负责钩子路径的安全约定；[自动配对合并 Agent Note](../.agents/notes/implemented/process/2026-08-08-automatic-translation-pairing-merges.md) 负责合并驱动。\n\n如果依赖是从缓存恢复或 `postinstall` 被跳过而导致任一集成缺失，请手动安装：\n\n```sh\nnode scripts/install-lefthook.mjs\n```\n\n如果包装脚本拒绝现有 Git 配置或报告陈旧锁，请遵循其诊断和所链接的 Agent Note，不要凭猜测编辑 worktree 元数据。移动检出目录后，请重新运行包装脚本以重新生成自有路径。\n\n新克隆后请先运行一次类型检查：\n\n```sh\npnpm run typecheck\n```\n\n`pnpm run typecheck` 成功退出即表示搭建完成。\n\n## 贡献者参考\n\n### TypeScript 项目布局\n\n仓库使用相互隔离的 Host 与 Client aggregate。普通 package 只登记进其中一个 aggregate；Host 包进入 `tsconfig.host.json`，Client 包进入 `tsconfig.client.json`。\n\n| 文件 | 角色 | 是否构成 program？ |\n|---|---|---|\n| `tsconfig.json` | solution 根：`extends` base、`files: []`、引用两个 aggregate。它是 tsserver 发现入口，也是显式执行整张 Project Reference 图时的入口；经继承的 `paths` 充当 tsx 运行 `examples/` 与 `scripts/` 时的解析配置。 | 否 |\n| `tsconfig.host.json` | Host aggregate：Host package、示例、测试、脚本和 website，以及 `api/remotes` 的 Host 特例 project。 | 是 |\n| `tsconfig.client.json` | Client aggregate：`packages/client/*` package 及其测试、`apps/web`，以及 `api/remotes` 的 Client 特例 project。 | 是 |\n| `tsconfig.base.json` | 共享 compilerOptions 与源码 `paths` 映射。同时是各 vitest 配置让 vite-tsconfig-paths 指向的解析门面：它没有 `include`，因此其 `paths` 适用于任何 importer。 | 否 |\n| `tsconfig.base.client.json` | 浏览器编译设置（`jsx`、DOM lib、`types: []`），由 Client aggregate 和每个 `packages/client/*` package extends。 | 否 |\n\nHost 与 Client 保持两个 aggregate program，是因为两侧在相同键下以不同服务对 cordis `Context` 接口做声明合并；单一 program 同时看到两份合并会报冲突。这种冲突只存在于 `ts.Program` 内部——模块解析永远不会触发它——所以 solution 可以同时引用两个 aggregate，一个 paths 门面也可以横跨两侧。由此推出三条纪律：\n\n- `tsconfig.base.json` 永不添加 `include` 或 `files`：它们会泄漏进每个 extends 它的包项目，并收窄门面的全匹配范围。\n- 构造全仓 `ts.Program` 的脚本显式种子 `tsconfig.host.json` 或 `tsconfig.client.json`——永不种子根 solution，因为把两个 aggregate 展平进一个 program 会撞上 `Context` 合并冲突。\n- 新 package 只登记进一个 aggregate。包同时具有 Node loader 入口和 browser 入口并不构成拆分理由；普通 Client plugin 的两份运行时产物都在 Client 构建阶段生成。\n\n`api/remotes` 是唯一拆分 Host/Client tsconfig 的仓库特例。它的 Host 入口必须进入 Host TypeRT 图，而 Client 入口导入 Host tsdown 才会生成的 `/remote` 声明，因此本包根 `tsconfig.json` 只作为 solution，两个 aggregate 和直接消费方分别引用 `tsconfig.host.json` 或 `tsconfig.client.json`。workspace `constraints` 门禁遍历可达的 Project Reference 图，并按各引用 project 自身的 compiler face 检查：只有单一配置的目标可由任一 face 引用，拆分配置的目标则必须引用匹配的 leaf，不得引用 solution 根或另一侧 leaf；该门禁按「两个 leaf 配置同时存在」自动发现拆分包，所以新拆分的包会自动纳入管辖。不要把该结构推广到其他包；[`api-remotes` README](../packages/api/remotes/README.md) 说明 Host/Client 拆分与构建顺序。\n\n根构建按生成依赖排序：\n\n```sh\ntsc -b tsconfig.host.json\ntsdown --env.DSH_BUILD_FACE host\ntsc -b tsconfig.client.json\ntsdown --env.DSH_BUILD_FACE client\npnpm run build:web\n```\n\n两次 tsdown 都使用同一组完整 workspace 匹配，不扫描构建产物来发现 Client package，也不维护 Host/Client package 过滤表。包内 tsdown 配置根据 `DSH_BUILD_FACE` 决定当前阶段的入口：普通 Client plugin 在 Client 阶段同时生成 Node loader 与 browser bundle；`api-remotes` 通过 `hostPhase: true` 提前生成 Host 入口，再在 Client 阶段只生成 browser bundle。tsdown 只消费 `lib/types` 中由前置 tsc 发射的 JavaScript。\n\nTypeRT 只在 Host tsdown 中以 `tsconfig.host.json` 为种子运行。它分析 Host 类型并生成 Host 反射产物及 Host-for-Client Remote 投影；Client tsdown 不启动 TypeRT。`pnpm run typecheck` 因此先执行完整 Host lib 阶段，再运行 Client tsc；`pnpm run build` 继续执行 Client tsdown 和 Web 构建。该顺序的决策记录见 [API Remotes 生成约定构建 Note](../.agents/notes/implemented/process/2026-08-08-api-remotes-generated-contract-build.md)。\n\n静态分析和测试通过 base 的 `paths` 映射把工作区 import 解析到 `src`，且必须在干净树上通过；消费构建产物 `lib/` 的门禁显式声明该依赖。生成的 Host-for-Client Remote 声明是有意设置的例外：公共 `typecheck`、`lint` 和 `doc-typecheck` 命令会先生成这些声明，而内部 `*:contracts-ready` 脚本假定调用它的公共命令或调度器门禁已经依赖 TypeRT 约定生成阶段或完整构建。两个 aggregate 的设置见 [solution-root Note](../.agents/notes/implemented/process/2026-07-22-tsconfig-solution-root-two-aggregates.md)，tsc-first 发射职责见 [ts-build-config Note](../.agents/notes/implemented/process/2026-06-17-ts-build-config.md)，门禁准备约定见 [TypeRT Remote Agent Note](../.agents/notes/implemented/architecture/2026-08-02-typert-remote-method-calls.md)。\n\n业务 Service 在 Host 使用 `@Remote` 或 `@RemoteScope` 声明可调用方法；Host 构建生成 Host-for-Client 类型与运行时贡献，Client 的 `api-remotes` 组合加载这些贡献并挂到 `ctx.remote` 与作用域 `agentCtx.remote` namespace。两侧的生成产物、装配关系、SRC 开发回退和 Web 构建顺序见 [API Gateway](api-gateway.md)。\n\n如果相关的本地检查需要使用构建后的包产物，请先构建一次：\n\n```sh\npnpm run build\n```\n\n`pnpm run hygiene` 包含 `publint`（用构建出的 `lib/*.js` 文件校验 package 入口点）和 `verify-node-next-types`（用一个临时的 NodeNext 消费方校验构建出的声明文件）。新 worktree 在 `pnpm run build` 运行之前没有打包的 JS 和声明文件；普通提交和推送无需构建，除非所选检查会使用这些产物。\n\n### 环境变量\n\n真实的 DeepSeek 适配器和需要密钥的 agent 演示从环境变量或仓库根目录一个被 gitignore 的 `.env` 文件读取凭证：\n\n```sh\nDEEPSEEK_API_KEY=sk-...\nDEEPSEEK_BASE_URL=https://... # optional\n```\n\n`DEEPSEEK_BASE_URL` 可选，默认为公开 API。请勿提交真实凭证。未设置 `DEEPSEEK_API_KEY` 时，真实 API 的 e2e 套件会自动跳过。\n\n### Git 集成\n\n当两种语言的文件都使用 Git 默认文本策略且能干净合并时，配对合并驱动会根据已确认的祖先、当前和另一侧的配对文档 blob，推导出发生冲突的 `.i18n.yaml` 记录。配对文档发生冲突、存在非文本合并配置或记录无效时，它会拒绝处理并保留冲突；如果合并已经因冲突而停止，请运行 `pnpm run resolve-translation-pairing-conflicts`，该命令会暂存每份可安全生成的配对记录；如果其他配对冲突仍需手工处理，则以非零状态退出。[双语文档约定](i18n/README.md#the-pairing-contract)列出该驱动接受的确切文件和状态。\n\n安装脚本在发布 worktree 配置前，会探测确切的 Node/tsx 驱动入口点。如果该运行时之后变得不可用，不依赖 Node 的启动器会写入 Git 的普通文本合并结果、让伴随文件保持未解决状态，并打印恢复路径；请恢复依赖后运行 `pnpm run resolve-translation-pairing-conflicts`，或运行 `git merge --abort`。如果 `pre-merge-commit` 拒绝原本能干净完成的合并，Git 会把完整结果留在暂存区但不创建提交；请修复失败后运行 `git commit`，或中止合并。确切的索引与 `MERGE_HEAD` 状态由[自动配对合并 Agent Note](../.agents/notes/implemented/process/2026-08-08-automatic-translation-pairing-merges.md#failure-contract)负责记录。\n\nlefthook 在 `lefthook.yml` 中配置，作为快速的本地检查点：\n\n- `pre-commit` 对照暂存的配对文档 blob 校验暂存的配对记录，使用不加载项目的 `.oxlintrc.staged.json` 配置验证暂存文件，并通过一次有界重试应用 Oxlint 修复，在暂存文件属于 `THIRD_PARTY_NOTICES.md` 的输入时重新生成该文件，然后检查暂存 diff 中的空白错误，并运行 vendor manifest（元数据清单）守卫；\n- `pre-merge-commit` 在 Git 创建自动合并提交前执行同样以索引为准的配对检查；\n- `pre-push` 运行 `pnpm run typecheck`；该命令会先完成包含 TypeRT 约定生成的完整 Host lib 阶段，再运行 Client TypeScript 检查。\n\nvendor manifest 守卫检查 `vendor/*/src` 下的改动是否连同对应的 `vendor/README.md` manifest 更新一起暂存。请在编辑 vendor 代码前先阅读 `vendor/README.md`。\n\n除限定范围的暂存记录校验外，这些钩子有意不运行测试、快照、文档检查、构建或 `hygiene`。贡献者只运行一次[与改动行为相关的检查](../AGENTS.md#run-relevant-checks-locally)；CI 负责全量覆盖率门禁、构建产物冒烟测试，以及 Node

         "role": "user",
-        "content": "# Bilingual documentation\n\nEnglish | [中文](README.zh.md)\n\nThis repo's documentation is read by people and agents both inside and outside the company, so every document in scope is maintained in English and Simplified Chinese. This page defines the pairing contract, checks, scope, and exclusions; [translation-rules.md](translation-rules.md) defines how to translate; [terminology.md](terminology.md) is the terminology source of truth. Routine agent work follows the lightweight path in [docs/AGENTS.md](../AGENTS.md); the extended [.agents/skills/dsh-translate-docs](../../.agents/skills/dsh-translate-docs/SKILL.md) workflow is available only through explicit user invocation.\n\n## The pairing contract\n\n- **Both languages carry equal authority.** A document may be authored and reviewed in either language first — a Chinese-first Agent Note is as legitimate as an English-first one — and the counterpart is translated from it. Neither file outranks the other; what binds them is that they must say the same thing.\n- **A pair is three sibling files.** The English `foo.md`, the Chinese `foo.zh.md`, and a consistency record `foo.i18n.yaml`, all in the same directory. No locale directories, no separate translation repo, no interleaved bilingual files. Pairs merge whole: a PR never lands one language without the other two files.\n- **The consistency record.** `foo.i18n.yaml` holds the full git blob hash of each side as of the last time the two were confirmed to say the same thing:\n\n  ```yaml\n  foo.md: 3f786850e387550fdab836ed7e6dc881de23001b\n  foo.zh.md: 89e6c98d92887913cadf06b2adb97f26cde4849b\n  ```\n\n  Blob hashes, not commit hashes, so the record is computable for files edited in the same PR (`git hash-object foo.md`) and consistency is a pure content comparison. `--write` stores those snapshots in the local Git object database before recording them, including uncommitted working-tree contents, and pins every distinct stored blob under a content-addressed `refs/dsh/translation-pairing/snapshots/` ref so garbage collection cannot invalidate a recorded recovery pointer. The recorded hashes therefore recover the exact last-confirmed text of either side, so an out-of-sync pair is updated by patching the counterpart minimally against the edited side's diff — never by re-translating whole files. Routine work makes that patch directly; when the user explicitly invokes the extended workflow, `pnpm run gen-translation-brief <pair>` can instead assemble the update at the narrowest safely aligned granularity and `--apply` can splice a code-fence-only change after structural validation ([briefed-updates Agent Note](../../.agents/notes/implemented/process/2026-07-26-briefed-minimal-translation-updates.md)). After bringing the pair back in line, `pnpm run verify-translation-pairing --write <pair>` re-records both hashes; that yaml diff is the reviewable act of confirming consistency, which is why `--write` requires naming the pairs you confirmed (`--write --all` is the explicit corpus-wide form).\n\n  When two branches contain valid confirmations of the same pair, the installed `dsh-translation-pairing` Git merge driver composes a new record only if Git's default text merge succeeds for both recorded owner-blob triplets and the merged pair retains its required switchers and structural signature. The Chinese file must retain its English backlink; an authored English source must retain its Chinese link, while a listed generated English source is exempt. Any structure the driver cannot verify remains an ordinary conflict; `pnpm run resolve-translation-pairing-conflicts` applies the same fail-closed operation to a merge that has already stopped, stages every safe pairing record, and exits unsuccessfully when other pairing conflicts remain. The [automatic pairing merges Agent Note](../../.agents/notes/implemented/process/2026-08-08-automatic-translation-pairing-merges.md) owns the mechanism and alternatives.\n- **Language switcher.** The Chinese file always links back immediately after its H1 heading with `[English](foo.md) | 中文`. An authored English file reciprocates there with `English | [中文](foo.zh.md)`; a listed generated English source omits that line so it remains byte-identical to generator output.\n- **Structure mirrors the counterpart.** Heading depths and order, list kinds, ordered-list starts, list item counts, table row and column counts, link targets, and verbatim code blocks match one to one across the pair — see [translation-rules.md](translation-rules.md) for the full preservation rules. Existing Markdown gates apply to `.zh.md` files unchanged (`verify-md-wrap`, `verify-md-links`).\n\n## The gate: verify-translation-pairing\n\n`pnpm run verify-translation-pairing` (part of `doc-sync`, which contributors run locally for documentation changes and CI runs exhaustively) enforces the contract mechanically:\n\n1. Every document in scope has a complete pair. README discovery is case-insensitive on the basename, so `missions/readme.md` is in scope alongside the other documentation roots.\n2. Every pair artifact that exists at all is complete and consistent: all three files present, each side's current blob hash equals the recorded one (editing either side without re-confirming the pair goes red), the Chinese side and every authored English source carry their language switchers (listed generated English sources are exempt), and the structural signatures match in order — heading depths, verbatim code blocks (info string and content), table row and column counts, list kinds, ordered-list starts, item counts, and every link target apart from the switcher.\n3. Files listed as `excluded` have no `.zh.md` and no `.i18n.yaml` at all. Frozen Agent Notes under `.agents/notes/archived/` are outside this evolving gate; their dedicated verifier requires and seals the complete existing triplet instead.\n\nSource-oriented code gates consume an exact `.zh.md` fence sequence as a derivative of its unsuffixed sibling instead of compiling or manifesting the same code twice. The sequence must match in length, order, fence kind, and byte-exact body; otherwise both copies remain independently checked and the pairing gate reports the structural mismatch.\n\n`pnpm run verify-translation-pairing --list` prints the current pairing state of every document in scope — missing, out-of-sync, or ok. It never fails; `missing` and `out-of-sync` rows identify violations that the normal check rejects.\n\n`pnpm run verify-translation-pairing <pair...>` checks just the named pairs — any of a pair's three files (or its bare stem) names it — so an update loop verifies its own pair in seconds instead of re-scanning the corpus. The no-argument corpus-wide form is what `doc-sync` and CI run; a scoped green never substitutes for it at PR level.\n\nThe practical rule this gate creates: **when a PR edits either side of a paired document, the same PR updates the counterpart directly in one terminology-guided pass and re-records the pair with `--write <pair>`**, exactly like the repo's existing doc-sync rule for code and READMEs. A PR that leaves a pair out of sync goes red in CI.\n\nThe gate's limit, stated plainly: **a green gate means the pair was confirmed consistent at these exact contents, not that the confirmation was sound.** It checks hashes and Markdown structure; it cannot judge whether the two sides actually say the same thing, or whether the wording is accurate, well-termed, and natural — that is the reviewer's half of the contract, per [translation-rules.md](translation-rules.md). A re-recorded pair with a sloppy counterpart passes the gate; it must not pass review.\n\n## Scope and exclusions\n\n**Scope**: every non-vendor README, plus every active document under `.agents/notes/**`, `docs/**`, and `python/**`. README matching is case-insensitive on the basename and covers future directories without another manifest edit. Dependency and ignored build-output trees and the frozen `.agents/notes/archived/` tree are discovery exclusions, not evolving translation source.\n\nGenerated English references and graphs participate in pairing when a reviewed Chinese counterpart is available. Their generators remain the English source of truth, and freshness and pairing gates enforce their respective invariants independently; regeneration that changes English leaves the pair out of sync until the reviewed Chinese counterpart is updated and re-recorded. Generated English sources omit the language switcher that ordinary authored sources carry, because adding it would make the generator stale; their Chinese counterparts still link back to the English source. A generated page's Chinese counterpart may rewrite only self-referential generation and maintenance statements that would otherwise be false for the reviewed translation; all technical content remains subject to the ordinary faithfulness rules.\n\n**Excluded** (never paired, and the gate rejects a `.zh.md` or `.i18n.yaml` for them):\n\n- [cordis-api/inherited.md](../cordis-api/inherited.md) — generated without a reviewed Chinese counterpart, so both website locales project the English source.\n- `docs/AGENTS.md`, `.agents/notes/**/AGENTS.md`, and their `CLAUDE.md` instruction symlinks — agent instructions, maintained in English only like the root `AGENTS.md`.\n- `docs/i18n/terminology.md` and [style-samples.md](style-samples.md) — both are bilingual by construction.\n- [translation-prompt.md](translation-prompt.md) — the automated pipeline's prompt template; its body is machine-consumed verbatim, so a paired translation would change pipeline behavior.\n- `.agents/notes/archived/` — frozen historical triplets. [`verify-archived-agent-notes`](../../scripts/verify-archived-agent-notes.ts) validates their completeness and content seals; translation maintenance must never rewrite them.\n\n**Universal requirement**: every current or future document in scope must merge as a complete bilingual pair. [scripts/translation-pairing.manifest.json](../../scripts/translation-pairing.manifest.json) contains only explicit exclusions; there is no per-file rollout list, date cutoff, or README-specific policy class.\n\n## Division of labor\n\nRoutine counterparts are updated directly by the working agent in one shot and one pass after it loads [terminology.md](terminology.md); it does not invoke a translation skill, generate a briefing, run a separate translation-review pass, or delegate to a subagent. The extended [dsh-translate-docs](../../.agents/skills/dsh-translate-docs/SKILL.md) workflow retains those heavier mechanisms for explicit user invocation. The gate checks pair completeness, recorded hashes, the Chinese backlink and authored-source switcher (with the documented generated-source exception), and its documented structural signature. Review still owns translation quality, terminology, and structural requirements that the signature does not encode. The prompt contract is executable: [scripts/translation-prompt.ts](../../scripts/translation-prompt.ts) renders the committed template (terminology injected; the template carries its own calibrated rules) into either direction and parses the three-section response, while `verify-translation-prompt` exercises both render directions and the checked-in example in `doc-sync`.\n"
+        "content": "# Bilingual documentation\n\nEnglish | [中文](README.zh.md)\n\nThis repo's documentation is read by people and agents both inside and outside the company, so every document in scope is maintained in English and Simplified Chinese. This page defines the pairing contract, checks, scope, and exclusions; [translation-rules.md](translation-rules.md) defines how to translate; [terminology.md](terminology.md) is the terminology source of truth. Routine agent work follows the lightweight path in [docs/AGENTS.md](../AGENTS.md); the extended [.agents/skills/dsh-translate-docs](../../.agents/skills/dsh-translate-docs/SKILL.md) workflow is available only through explicit user invocation.\n\n## The pairing contract\n\n- **Both languages carry equal authority.** A document may be authored and reviewed in either language first — a Chinese-first Agent Note is as legitimate as an English-first one — and the counterpart is translated from it. Neither file outranks the other; what binds them is that they must say the same thing.\n- **A pair is three sibling files.** The English `foo.md`, the Chinese `foo.zh.md`, and a consistency record `foo.i18n.yaml`, all in the same directory. No locale directories, no separate translation repo, no interleaved bilingual files. Pairs merge whole: a PR never lands one language without the other two files.\n- **The consistency record.** `foo.i18n.yaml` holds the full git blob hash of each side as of the last time the two were confirmed to say the same thing:\n\n  ```yaml\n  foo.md: 3f786850e387550fdab836ed7e6dc881de23001b\n  foo.zh.md: 89e6c98d92887913cadf06b2adb97f26cde4849b\n  ```\n\n  Blob hashes, not commit hashes, so the record is computable for files edited in the same PR (`git hash-object foo.md`) and consistency is a pure content comparison. `--write` stores those snapshots in the local Git object database before recording them, including uncommitted working-tree contents, and pins every distinct stored blob under a content-addressed `refs/dsh/translation-pairing/snapshots/` ref so garbage collection cannot invalidate a recorded recovery pointer. The recorded hashes therefore recover the exact last-confirmed text of either side, so an out-of-sync pair is updated by patching the counterpart minimally against the edited side's diff — never by re-translating whole files. Routine work makes that patch directly; when the user explicitly invokes the extended workflow, `pnpm run gen-translation-brief <pair>` can instead assemble the update at the narrowest safely aligned granularity and `--apply` can splice a code-fence-only change after structural validation ([briefed-updates Agent Note](../../.agents/notes/implemented/process/2026-07-26-briefed-minimal-translation-updates.md)). After bringing the pair back in line, `pnpm run verify-translation-pairing --write <pair>` re-records both hashes; that yaml diff is the reviewable act of confirming consistency, which is why `--write` requires naming the pairs you confirmed (`--write --all` is the explicit corpus-wide form).\n\n  When two branches contain valid confirmations of the same pair, the installed `dsh-translation-pairing` Git merge driver composes a new record only if Git's default text merge succeeds for both recorded owner-blob triplets and the merged pair retains its required switchers and structural signature. The Chinese file must retain its English backlink; an authored English source must retain its Chinese link, while a listed generated English source is exempt. Any structure the driver cannot verify remains an ordinary conflict; `pnpm run resolve-translation-pairing-conflicts` applies the same fail-closed operation to a merge that has already stopped, stages every safe pairing record, and exits unsuccessfully when other pairing conflicts remain. The [automatic pairing merges Agent Note](../../.agents/notes/implemented/process/2026-08-08-automatic-translation-pairing-merges.md) owns the mechanism and alternatives.\n- **Language switcher.** The Chinese file always links back immediately after its H1 heading with `[English](foo.md) | 中文`. An authored English file reciprocates there with `English | [中文](foo.zh.md)`; a listed generated English source omits that line so it remains byte-identical to generator output.\n- **Structure mirrors the counterpart.** Heading depths and order, list kinds, ordered-list starts, list item counts, table row and column counts, link targets, and verbatim code blocks match one to one across the pair — see [translation-rules.md](translation-rules.md) for the full preservation rules. Existing Markdown gates apply to `.zh.md` files unchanged (`verify-md-wrap`, `verify-md-links`).\n\n## The gate: verify-translation-pairing\n\n`pnpm run verify-translation-pairing` (part of `doc-sync`, which contributors run locally for documentation changes and CI runs exhaustively) enforces the contract mechanically:\n\n1. Every document in scope has a complete pair. README discovery is case-insensitive on the basename, so `missions/readme.md` is in scope alongside the other documentation roots.\n2. Every pair artifact that exists at all is complete and consistent: all three files present, each side's current blob hash equals the recorded one (editing either side without re-confirming the pair goes red), the Chinese side and every authored English source carry their language switchers (listed generated English sources are exempt), and the structural signatures match in order — heading depths, verbatim code blocks (info string and content), table row and column counts, list kinds, ordered-list starts, item counts, and every link target apart from the switcher.\n3. Files listed as `excluded` have no `.zh.md` and no `.i18n.yaml` at all. Frozen Agent Notes under `.agents/notes/archived/` are outside this evolving gate; their dedicated verifier requires and seals the complete existing triplet instead.\n\nSource-oriented code gates consume an exact `.zh.md` fence sequence as a derivative of its unsuffixed sibling instead of compiling or manifesting the same code twice. The sequence must match in length, order, fence kind, and byte-exact body; otherwise both copies remain independently checked and the pairing gate reports the structural mismatch.\n\n`pnpm run verify-translation-pairing --list` prints the current pairing state of every document in scope — missing, out-of-sync, or ok. It never fails; `missing` and `out-of-sync` rows identify violations that the normal check rejects.\n\n`pnpm run verify-translation-pairing <pair...>` checks just the named pairs — any of a pair's three files (or its bare stem) names it — so an update loop verifies its own pair in seconds instead of re-scanning the corpus. The no-argument corpus-wide form is what `doc-sync` and CI run; a scoped green never substitutes for it at PR level.\n\nThe practical rule this gate creates: **when a PR edits either side of a paired document, the same PR updates the counterpart directly in one terminology-guided pass and re-records the pair with `--write <pair>`**, exactly like the repo's existing doc-sync rule for code and READMEs. A PR that leaves a pair out of sync goes red in CI.\n\nThe gate's limit, stated plainly: **a green gate means the pair was confirmed consistent at these exact contents, not that the confirmation was sound.** It checks hashes and Markdown structure; it cannot judge whether the two sides actually say the same thing, or whether the wording is accurate, well-termed, and natural — that is the reviewer's half of the contract, per [translation-rules.md](translation-rules.md). A re-recorded pair with a sloppy counterpart passes the gate; it must not pass review.\n\n## Scope and exclusions\n\n**Scope**: the root CONTRIBUTING document, every non-vendor README, and every active document under `.agents/notes/**`, `docs/**`, and `python/**`. README matching is case-insensitive on the basename and covers future directories without another manifest edit. Dependency and ignored build-output trees and the frozen `.agents/notes/archived/` tree are discovery exclusions, not evolving translation source.\n\nGenerated English references and graphs participate in pairing when a reviewed Chinese counterpart is available. Their generators remain the English source of truth, and freshness and pairing gates enforce their respective invariants independently; regeneration that changes English leaves the pair out of sync until the reviewed Chinese counterpart is updated and re-recorded. Generated English sources omit the language switcher that ordinary authored sources carry, because adding it would make the generator stale; their Chinese counterparts still link back to the English source. A generated page's Chinese counterpart may rewrite only self-referential generation and maintenance statements that would otherwise be false for the reviewed translation; all technical content remains subject to the ordinary faithfulness rules.\n\n**Excluded** (never paired, and the gate rejects a `.zh.md` or `.i18n.yaml` for them):\n\n- [cordis-api/inherited.md](../cordis-api/inherited.md) — generated without a reviewed Chinese counterpart, so both website locales project the English source.\n- `docs/AGENTS.md`, `.agents/notes/**/AGENTS.md`, and their `CLAUDE.md` instruction symlinks — agent instructions, maintained in English only like the root `AGENTS.md`.\n- `docs/i18n/terminology.md` and [style-samples.md](style-samples.md) — both are bilingual by construction.\n- [translation-prompt.md](translation-prompt.md) — the automated pipeline's prompt template; its body is machine-consumed verbatim, so a paired translation would change pipeline behavior.\n- `.agents/notes/archived/` — frozen historical triplets. [`verify-archived-agent-notes`](../../scripts/verify-archived-agent-notes.ts) validates their completeness and content seals; translation maintenance must never rewrite them.\n\n**Universal requirement**: every current or future document in scope must merge as a complete bilingual pair. [scripts/translation-pairing.manifest.json](../../scripts/translation-pairing.manifest.json) contains only explicit exclusions; there is no per-file rollout list, date cutoff, or README-specific policy class.\n\n## Division of labor\n\nRoutine counterparts are updated directly by the working agent in one shot and one pass after it loads [terminology.md](terminology.md); it does not invoke a translation skill, generate a briefing, run a separate translation-review pass, or delegate to a subagent. The extended [dsh-translate-docs](../../.agents/skills/dsh-translate-docs/SKILL.md) workflow retains those heavier mechanisms for explicit user invocation. The gate checks pair completeness, recorded hashes, the Chinese backlink and authored-source switcher (with the documented generated-source exception), and its documented structural signature. Review still owns translation quality, terminology, and structural requirements that the signature does not encode. The prompt contract is executable: [scripts/translation-prompt.ts](../../scripts/translation-prompt.ts) renders the committed template (terminology injected; the template carries its own calibrated rules) into either direction and parses the three-section response, while `verify-translation-prompt` exercises both render directions and the checked-in example in `doc-sync`.\n"

会把仓库内置的模板（注入术语表；模板自带经人工校准的规则）渲染为英译中或中译英两个方向的提示词，并解析三段式响应；`doc-sync` 中的 `verify-translation-prompt` 会检查两个渲染方向与仓库内示例。\n"

@@ -44,10 +44,9 @@ Keep this log exhaustive — every divergence from upstream must be listed.
 12. **`include/src/index.ts` serialized child-tree mutation and `hmr/src/index.ts` main-watcher initial-scan suppression**: every Include child-tree mutation (initial apply, refresh, `internal/update` patch re-application) runs through one per-Include queue, because the group's transactional `update` is not reentrant — two concurrent applies interleave create and rollback on the same entries and strand the Include fiber without ever settling. The HMR main watcher passes `ignoreInitial: true`: the initial scan re-announced files boot had just consumed, and its `add` for a config file refreshed an Include mid-initial-apply; once serialized, a failing initial apply's rollback disposed HMR, whose teardown drain waited on the queued refresh sitting behind that same apply — a deadlock that exited 13 with no diagnostic. `registerConfig()` keeps its own `ignoreInitial: false` watcher because a user patch layer present at registration must apply once. Covered by the patch-overlay boot-failure built-bin case in `apps/cli/tests/built-bin.e2e.ts`.
 13. **`include/src/index.ts` `writeTask` type**: widened the optional `writeTask?: NodeJS.Timeout` property to `NodeJS.Timeout | undefined` — the debounced writer assigns `undefined` on flush, which `exactOptionalPropertyTypes` rejects on a plain optional. Type-only; no behavior change.
 14. **`include/src/index.ts` durable debounced writes**: serialized and tracked config-file writes, retried transient `EACCES`/`EBUSY`/`EPERM` rename failures with a bounded backoff, observed asynchronous timer rejections, and drained the latest write during Include teardown. Windows can briefly retain a destination handle after a Loader child disposes; the upstream fire-and-forget rename escaped as an unhandled rejection and could lose the persisted `disabled` state. A terminal failure is logged by the asynchronous writer and remains on the queue so `Include.stop()` rethrows it instead of silently declaring persistence complete; Cordis's ordinary fiber teardown retains its separate error-containment contract. Covered by `packages/host/directory-picker-auto/tests/loader-composition.spec.ts` with injected transient and terminal rename failures.
-15. **Lazy Loader config resolution across `cordis/src/{events,fiber}.ts`, `loader/src/{index,config/entry}.ts`, `include/src/index.ts`, and `hmr/src/index.ts`**: ports [cordiverse/cordis#41](https://github.com/cordiverse/cordis/pull/41), retaining raw fiber config and resolving it through `internal/config` only after declared injections are active. Provider replacement re-resolves the raw expression, pending updates retain it, and HMR transfers it. Resolution applies only to the entry root, so child plugins mounted by a row keep caller-owned config identity. Include adds a static entry-config resolver so its own options interpolate while nested row `!!js` nodes remain deferred. Deferred failures retain the owning row diagnostic, and tree teardown does not persist failure-driven self-disposal. Covered by `packages/boot/app-boot/tests/{app-boot,user-patches}.spec.ts`, `packages/boot/cmdline/tests/cmdline.spec.ts`, `apps/cli/tests/web-agent-presets.e2e.ts`, and the built custom-profile cases in `apps/cli/tests/built-bin.e2e.ts`.
-16. **In-memory Loader entry activation in `loader/src/config/entry.ts`**: an invocation can activate a row shipped with `disabled: true` without mutating its serialized options. The override belongs to the mounted entry object, survives Include config reapplication, respects disabled ancestors, and disappears with the entry. Covered by `packages/boot/cmdline/tests/cmdline.spec.ts` and `apps/web/tests/hmr-live.e2e.ts`.

Provider replacement re-resolves the raw expression, pending updates retain it, and HMR transfers it. Resolution applies only to the entry root, so child plugins mounted by a row keep caller-owned config identity. Include declares the `EntryGroup.key` tree-carrier marker (as Group does): its config is entry and patch lists, so interpolation keeps it literal and a `!!js` expression inside a nested row's config resolves lazily in that row's own fiber (Include's own `path` therefore stays literal too). Deferred failures retain the owning row diagnostic, and tree teardown does not persist failure-driven self-disposal. Covered by `packages/boot/app-boot/tests/{app-boot,user-patches}.spec.ts`, `packages/boot/cmdline/tests/cmdline.spec.ts`, `apps/cli/tests/web-agent-presets.e2e.ts`, and the built custom-profile cases in `apps/cli/tests/built-bin.e2e.ts`.
+16. **`cordis/package.json` publishes `src`**: added `src` to the `files` list, joining the other eight vendored packages. Cordis declares `"./src/*": "./src/*"` in its exports, so a tarball without `src` publishes an export map pointing at absent files; the release change judgement also reads `files` to decide whether a diff reaches the payload, and a package whose only published paths are build output has no tracked path to match.
 17. **`@deepseek-ai` rescope**: every vendored manifest `name`, every internal dependency entry among the vendored set, and every module specifier that reaches them use the scoped names in the manifest table's `npm name` column. Directory names, version numbers, and dependency ranges are unchanged, and no upstream runtime identifier is renamed — `Symbol.for('schemastery')` and Schemastery's `vendor:` metadata field keep their upstream values. Re-apply with `pnpm run rescope-vendor --apply` after a sync; the table's two name columns are the mapping, restated for consumers in [docs/rescope.md](../docs/rescope.md).
