+# Agent Note: todo event types belong to their producer
+
+Status: implemented
+
+English | [中文](2026-07-20-todo-event-ownership.zh.md)
+
+## Problem
+
+`SessionEventMap` is merge-extensible so each plugin can add durable records without making the core session package depend on every event producer. `todo/write` and its `TodoItem` payload are produced and interpreted by the todo domain, while core session only provides the generic append, replay, surface, and invariant extension mechanisms. Declaring todo-specific types or relationships in core would make the session spine own a plugin vocabulary it cannot produce or validate completely.
+
+## Decision
+
+`@deepseek-ai/dsh-tool-todo` declares `TodoItem` and merges `todo/write` into `@deepseek-ai/dsh-session/types` from its type-only outlet. The package root and `/client` entrypoint re-export `TodoItem`, so host and browser consumers share one declaration without loading the todo plugin.
+
+Consumers that inspect todo records use type-only imports plus explicit package dependencies and TypeScript project references. The emitted JavaScript has no todo import, and a composition does not need to mount the todo tool merely to search, transmit, or render a log that may contain `todo/write`.
+
+The todo invariant companion owns both the payload rules and the event's relationship to an open turn. Core session's merge-extensible switch falls through for `todo/write`, while the todo companion rejects malformed snapshots and snapshots outside an open turn before append. It validates existing and newly announced sessions in one pass and advances a committed per-session turn trace for later events. Todo-specific append, replay, projection, and enclosure tests live with the todo package. The model-facing behavior remains owned by the [`todo_write` feature decision](../feature/2026-06-29-todo-write-tool.md).
+
+## Verification
+
+Focused todo tool, invariant, projection, integration, and Loader-composition tests exercise the producer and its companion. Session-query extraction and client runtime/connection tests prove type-only consumers retain semantic todo handling. Workspace typecheck proves declaration merging through the explicit project graph; generated event, persistence, API, and module catalogs record the declaration site and dependency edges.
+
+## Alternatives considered
+
+- **Keep the payload type in core as shared UI vocabulary** — rejected because rendering reuse does not make core the producer or semantic owner of the durable event.
+- **Narrow `todo/write` structurally in each consumer** — rejected because duplicate payload declarations can drift and bypass the merge-extensible event map.
+- **Require every consumer to mount the todo plugin** — rejected because reading a durable record is a type and data dependency, not authorization to install a model-facing tool.
+
+## Consequences
+
+The core session package does not export `TodoItem` or enforce todo relationships. A package that names or narrows `todo/write` declares a type-only dependency on `dsh-tool-todo`; consumers that treat unknown merged events generically need no dependency. The todo package is the single source for the event payload, client type, runtime validation, and open-turn rule.

+# Agent Note: todo 事件类型归其生产方所有
+
+Status: implemented
+
+[English](2026-07-20-todo-event-ownership.md) | 中文
+
+## 问题
+
+`SessionEventMap` 可通过声明合并扩展，使每个插件都能添加持久记录，而无需让核心会话包依赖所有事件生产方。`todo/write` 及其 `TodoItem` payload 由 todo 领域生产和解释；核心会话只提供通用的追加、回放、surface 与不变量扩展机制。在核心中声明 todo 专属类型或关系，会让会话主干拥有一个它既不生产、也无法完整校验的插件词汇。
+
+## 决策
+
+`@deepseek-ai/dsh-tool-todo` 在其仅类型出口中声明 `TodoItem`，并通过 `@deepseek-ai/dsh-session/types` 的声明合并加入 `todo/write`。包根入口和 `/client` 入口重新导出 `TodoItem`，使 host 与浏览器消费方共享同一处声明，而无需加载 todo 插件。
+
+检查 todo 记录的消费方使用仅类型导入，并声明显式包依赖与 TypeScript 项目引用。产出的 JavaScript 不含 todo 导入；组合仅为了搜索、传输或渲染可能含有 `todo/write` 的日志时，无需挂载 todo 工具。
+
+todo 不变量配套插件同时拥有 payload 规则和事件必须位于开放轮次内的关系。核心会话的可合并扩展 switch 对 `todo/write` 走默认分支；todo 配套插件会在追加前拒绝格式错误或位于开放轮次之外的快照。它会单次校验现有会话与新发布的会话，并为后续事件推进逐会话的已提交轮次追踪状态。todo 专属的追加、回放、投影和轮次封闭测试与 todo 包放在一起。面向模型的行为仍由 [`todo_write` 功能决策](../feature/2026-06-29-todo-write-tool.zh.md)负责。
+
+## 验证
+
+聚焦的 todo 工具、不变量、投影、集成和 Loader 组合测试覆盖生产方及其配套插件。session-query 提取与客户端 runtime/connection 测试证明仅类型消费方仍能保留 todo 的语义处理。全工作区类型检查证明声明合并通过显式项目图生效；重新生成的事件、持久化、API 与模块目录记录声明位置和依赖边。
+
+## 曾考虑的替代方案
+
+- **把 payload 类型留在核心中作为共享 UI 词汇**——拒绝：渲染复用并不会让核心成为持久事件的生产方或语义所有方。
+- **让每个消费方各自按结构收窄 `todo/write`**——拒绝：重复的 payload 声明会漂移，并绕过可合并扩展的事件表。
+- **要求每个消费方都挂载 todo 插件**——拒绝：读取持久记录是类型和数据依赖，并不构成安装面向模型工具的授权。
+
+## 后果
+
+核心会话包不导出 `TodoItem`，也不强制 todo 关系。命名或收窄 `todo/write` 的包声明对 `dsh-tool-todo` 的仅类型依赖；只把未知合并事件作通用处理的消费方无需依赖它。todo 包是事件 payload、客户端类型、运行时校验和开放轮次规则的唯一来源。

Code Mode and Session persistence are one-shot Agent capabilities independent of Web presentation.
 
 `headless-runner` is a direct core entry point. After Loader settlement, it reads `ctx.agentDefaultModel.currentSelection()`, creates a fresh persisted Agent through `ctx.agents.create`, installs that `ModelSelection` in the Agent scope, waits for startup quiescence, anchors the Session sequence, submits one ordinary user message, and waits for quiescence again. It awaits `ctx.sessions.flush`, folds its durable event interval for the last non-empty assistant text and final `turn/end` reason, writes the text plus one newline to stdout, and requests bounded launcher shutdown with exit 0 exactly when the reason is `completed`. A terminal `error` reason writes its durable code and message to stderr; unexpected driver failures also use stderr and exit 1.

 ## 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.
+[Typert Remote method calls](../../implemented/architecture/2026-08-02-typert-remote-method-calls.md) initially cover targeted calls with one result per request and deliberately leave Session streams and stateful interactions elsewhere. Host-to-consumer events need a delivery mechanism that is not owned by the API Proxy domain.
 
-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/reference-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.
+The Host owns one-way events such as `agent-preset/selected`, `commands/change`, `credentials/reference-updated`, `llm/adapters-updated`, and `settings/document-updated`. They do not depend on AgentScope, and their payloads are already JSON. Requiring every event to cross a handwritten API Proxy frame, a handwritten Client Runtime bridge, and a Client event alias adds no fact beyond the owner event declaration.
 
-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.
+That duplicate declaration is also lossy: the Client side restates an event as `settings/changed(ns: string)`, flattening a branded type to bare `string`, contrary to the Remote-method rule that consumer types point to the business package's one canonical symbol.
 
 ## Decision
 
-The consumer Remote surface carries one one-way subscription verb, `ctx.remote.$on(event, listener)`, driven by an allowlist and forwarding verbatim:
+The consumer Remote surface has one event-subscription verb, `ctx.remote.$on(event, listener)`, with allowlist-driven, verbatim forwarding:
 
-- `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 `$on`'s listener type is `Events[Event]` itself. "Verbatim" then holds by construction rather than by proof.
-- Only cordis's *type shape* is borrowed, not its event system: delivery semantics, the subscription registry, and failure containment belong to Typert.
+- `packages/api/remotes/src/remote-events.ts` owns one list of forwardable Host events with explicit `emit`/`waterfall` modes. It is also the sole control point for what consumers may subscribe to. Adjacent `src/types.ts` derives the type projection and fills the selection seat while remaining type-only. Both files appear in the `files` of the package's Host and Client faces, so both read one declaration.
+- The event name on the wire is the original Host Cordis name (`settings/document-updated`) without a `host/` prefix. The payload is the Host argument list, element for element through JSON, without projection, redaction, or renaming.
+- `api/remotes` registers the Host source with API Gateway. Gateway reserves internal logical endpoint `$events` on the existing `/api/remote.mux`, adding no physical connection and giving API Proxy no event interpretation. Waterfall results return through HTTP unary endpoint `$events/result`.
+- Event signatures have no second table. Owner packages place their Cordis `Events` declarations in Client-safe, type-only `./types` exports so both faces read the same declaration. `$on` listener parameters, result, and `next()` derive from `Events[Event]`; verbatim correspondence holds by construction.
+- Only Cordis's type declarations are shared. Delivery semantics, registration, and failure handling 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.
+When an `Events` member reaches a Host-only symbol such as a Service, `Agent`, or Context, the code is split until the declaration can live cleanly in `./types`. A declaration is never split between `index.ts` and `types.ts`, and `types.ts` does not invent a structurally equivalent shadow type. Every current owner exposes its selected event declaration from a Client-safe type export.
 
-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).
+All allowlisted events use this path, and dedicated frames and Client aliases are removed. Model consumers subscribe directly to `llm/adapters-updated` and `settings/document-updated`; preset consumers subscribe to `agent-preset/selected`; stateless Session and dynamic-Cordis notifications use `emit`; Approval and Question use Agent-scoped `waterfall`. Data that needs a baseline, projection, or deduplication retains a dedicated Remote stream.
 
-`skills/change`, `tools/change`, and `system-prompt/change` have the same shape but **no shipped consumer**; under "require a current owner and need" they stay out of the allowlist and are recorded here only as the extension seat.
+`skills/change`, `tools/change`, and `system-prompt/change` have the same pure invalidation form but no shipped consumer. The rule that every abstraction needs a current owner and need keeps them outside the allowlist; they remain only an extension point recorded here.

+`Events` resolves per program: the complete Host event vocabulary in a Host program and only declarations visible to the Client compilation face in a Client program. The same predicate therefore holds on both sides without bringing 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 the implicit `PLATFORM_MODULES` plus `PRELOADED_CLIENT_EXTERNALS` baseline, the package's `dsh.client.external` requests, the `INLINE_SAFE` wire layer, and generated `/remote` contributions. 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:
+**The contract exposes only the consumer verb.** `ClientRemoteService` registers the one internal `$events` pump as a Connection generation source when it activates, independently of whether any `$on` subscription exists. Browsers open `$events` through the shared Remote mux; in-process compositions open the same logical stream through `connection.rpc.open`. Decoding, exact item validation, and Cordis dispatch are private Gateway Client implementation. `TypertClientRemote` exposes no producer operation, so a business plugin cannot synthesize a Host event.
 
-```ts ignore-check
-$dispatch(event: string, args: readonly unknown[]): void
-```
+Each time the Host opens `$events`, the API Remotes source factory installs every allowlist listener synchronously. Gateway then yields the opening `{ type: 'ready' }` before iterating the event source. `ConnectionController` waits for that ready item and `host.describe` in parallel and publishes `connected` only after both succeed, so baseline reads cannot race ahead of incremental listeners.
 
-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.
+A physical mux disconnect ends the logical stream with `RemoteStreamCarrierError`. A Host Remote stream error, unexpected normal completion, non-ready opening item, or malformed event item also ends the current generation. Connection withdraws that generation's `hostDescription` and reopens `$events` and `host.describe` after backoff; Gateway mux only rebuilds the physical WebSocket. Ordinary events are not replayed. State whose correctness requires recovery must provide a query, cursor, or opening baseline and cannot treat `$on` as a reliable journal.
 
-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 Client dispatches on a Cordis key private to each Remote instance. Ordinary `emit` uses `parallel()` and contains listener failures; Agent-scoped `waterfall` uses `waterfall()` on the resolved Agent Context and allows a result, rejection, or `next()` delegation. Both registration kinds belong to the calling fiber, and Host events do not trigger same-named Client-local events.

 ```
 
-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 `$on('skills/change', …)` (declared but unselected) are both **compile errors**.
+Adding an event is therefore one array entry: type projection, the `$on` key set, Host dispatch mode, and the forwarding loop all derive from it. `ctx.remote.$on('slots/changed', …)` for a Client-local event and `$on('skills/change', …)` for a declared but unselected event are compile errors.
 
-The Host face adds one shape assertion, binding the Host event vocabulary to that same array:
+The declaration's trailing `satisfies` applies Host event-vocabulary and mode constraints to the same allowlist:
 
 ```ts ignore-check
-API_REMOTE_FORWARDED_EVENTS satisfies readonly TypertForwardableEvent[]
+API_REMOTE_FORWARDED_EVENTS satisfies readonly TypertForwardableEventEntry[]
 ```
 
-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).
+It enforces three properties: the name exists because the predicate is keyed by `keyof Events`; the selected mode matches the signature; and the signature is either an unscoped `void` notification or a waterfall with top-level Agent scope, a same-result `next()`, and a Promise return. Other Scope, bail, parallel, and serial forms are excluded.
 
-**"Verbatim" is proved nowhere because it holds by construction**: `$on`'s listener type comes from the one cordis `Events` declaration in the owner package's `./types`, and Host forwarding reads that same declaration. There is no second declaration that could drift.
+Verbatim correspondence is not proved separately because it holds by construction. `$on`'s listener type and Host forwarding both read the owner package's one Cordis `Events` declaration, so no second declaration can 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.
+JSON safety remains a runtime concern. Before queueing, the API Remotes Host source checks every argument with `dsh-session`'s `isJsonValue` and fails loudly when one is invalid, because this is an allowlist composition error rather than untrusted input.
 
-### Wire contract (apiproxy)
+### Wire protocol (API Gateway Remote mux)
 
 ```ts ignore-check
-| { type: 'host/remote-event'; event: string; args: JsonValue[] }
+ready     { type, clientId }
+emit      { type, event, args }
+waterfall { type, event, eventId, agentId, request }
+cancel    { type, eventId }
 ```
 
-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`.
+The Client opens internal logical stream `$events` with payload `{ args: {} }`. Gateway rejects extra parameters, a missing Host source, and duplicate source registration. Withdrawing a source aborts every stream opened by that registration. Each Client stream owns an independent queue and allowlist listener set in `api/remotes`, so disconnecting one Client neither consumes nor withdraws another Client's events.
 
-`events.host()` subscribes by allowlist when the stream opens. Each stream owns its disposers, so no broadcast set or derived invalidation listener is needed.
+The Client requires an opening `ready` item with a non-empty `clientId`; every later item is checked for exact fields by discriminant. An ordinary `emit` with an unknown but structurally valid event name is dropped when there is no subscriber. Waterfalls use `eventId` to correlate `$events/result` and `agentId` to select a Client Agent Context. The Client returns only values representable as lossless JSON; transport does not reinterpret business fields.
 
-`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-input-trigger` and `ui-conversation`. `JsonValue` therefore needs a re-export from `dsh-session/src/types.ts`.
+`$events` is an internal Gateway endpoint. It does not enter a generated Typert Remote descriptor or become `ctx.remote.<namespace>`. Application selection exists only in the API Remotes allowlist and Host source; Gateway owns registration, payload validation, and physical transport only.
 
-### The apps/web browser e2e belong to the Host face
+### The `apps/web` browser e2e belongs 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.
+The `apps/web/tests/**` e2e files typecheck in root `tsconfig.host.json`: they boot a real harness in process and directly access `ctx.apiProxy`, Host `SessionStore.get/create/flush`, and `ctx.sessionProjectionCache`. Driving a browser at runtime does not place a file in the Client TypeScript program. Moving these tests to the Client aggregate 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-settings-models`, `ui-permission`, `ui-commands`) 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.
+This implies one build rule needed by the design: importing a value or type from a Client package in those tests brings that package's whole project and all its project references into the Host build graph. Four consumers (`ui-settings-general`, `ui-settings-models`, `ui-permission`, and `ui-commands`) reference API Remotes' Client face, which cannot compile until Host tsdown generates `@deepseek-ai/dsh-goal/remote`. That forms a build-order cycle: Host tsc needs API Remotes Client, which needs generated `goal/remote`, which Host tsdown emits 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.

Each mirror is byte-identical to its source; drift produces a selector mismatch or an unsuppressed notice and fails loudly.

-| `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.$dispatch(frame.event, frame.args)`, adding a `remote` injection and deleting their duplicated `Events` declarations |
-| Seven consumers | ui-commands / ui-model-selection / ui-settings-models / ui-settings-general / ui-permission / ui-agent-preset / ui-skill subscribe through `ctx.remote.$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 |
+| `dsh-typert-protocol` | `src/types.ts` provides forwardable-mode derivation, selection, and Client-listener projection; `TypertClientRemote` exposes only `$on`. Types only, no runtime |
+| `api/gateway` | Host provides one Remote event source, `$events`, pending-waterfall coordination, and `$events/result`; Client registers the private pump as the Connection generation source and owns frame validation and Cordis dispatch |
+| `api/remotes` | `src/remote-events.ts` (mode-bearing allowlist value) and `src/types.ts` (key projection and selection) belong to both faces; Host registers each Client source and validates JSON before queueing; Client continues to compose generated Remote contributions |
+| Root `tsconfig.base.json` | Adds source-plane `paths` entries for `dsh-settings/types`, `dsh-credentials/types`, and `dsh-api-remotes/types` |
+| `dsh-commands` / `dsh-settings` / `dsh-credentials` | Moves each `interface Events` member to the owner's Client-safe `./types`; settings and credentials add that export, move brands and pure types with it, retain constructors in index, and include `lib/types/**/*.js` in published files |
+| `host/apiproxy` | Contains no `HostFrame`, `events.host()`, or other Host downlink carrier; API Proxy does not participate in Host events or Connection generation |
+| `dsh-session` | Exposes `isJsonValue` for validation of every event argument by the API Remotes Host source |
+| `client/runtime` | Removes the bridge from Host frames to the Remote subscription table; it only publishes `connection/reset` after a Connection generation is established |
+| Consumers | Client plugins subscribe directly through `ctx.remote.$on(...)`, import owner event declarations type-only, and inject `'remote'` |
+| `client/connection` | Provides the one generation-source registration point; `ConnectionController` combines `$events` ready with `host.describe`, and the fixture emits events from the same source |
+| `apps/web/tests` + `apps/cli` | Mirrors Client symbols on the test side as described above and removes 15 Client project references from `apps/cli/tsconfig.json` |
 
 ## 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.
+**Continue using API Proxy's Host downlink.** This reuses Connection generation and `connection/reset` but leaves the Remote event allowlist, queue, schema, and Client Runtime bridge in API Proxy and prevents domain transports from sharing the lifecycle of other Remote streams. With API Gateway's resident `/api/remote.mux`, `$events` adds only one internal logical stream and belongs naturally in Gateway.
 
-**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.
+**Open a third physical WebSocket or duplex stream for Remote events.** An independent channel could own connection state but would duplicate authenticated upgrade, multiplexing, cancellation, error mapping, and reconnect backoff already provided by Gateway mux. Internal `$events` retains an independent logical stream, while waterfall results reuse HTTP unary calls.
 
-**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.
+**Declare a separate `TypertRemoteEventMap` in type metadata and let owner packages declaration-merge into it.** The consumer key set would exactly equal remotely deliverable events, but every signature would be written again outside Cordis `Events`, requiring a bidirectional equivalence proof and new type-metadata dependencies for owner packages. Sharing one `Events` declaration makes equivalence structural, so the second map is not created.
 
-**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.
+**Have the Typert generator project Host `Events` declarations.** The generator already analyzes Host events, but it cannot infer projection or redaction intent and would expand the generator and build surface. Verbatim forwarding needs no projection.
 
-**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`.
+**Give forwardable events a payload projection function.** A `{ event, project, zod }` table could combine model-directory inputs and derive Workspace views, but would manually align projection logic with payload types and recreate the central table removed from Remote methods.
 
-**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.**
+**Move the `apps/web` browser e2e into the Client aggregate.** The intuition that browser tests belong to the Client face fails with 21 errors because the tests use Host services while the Client program's `ctx.sessions` is `ISessions`.
 
-## Verification
+**Split `directory-picker-browse`/`-native` into Host and Client faces.** This would remove Client packages from the Host graph, but changes another owner's packages for only a cleaner build graph. Mirroring the required Client symbols on the test side removes the need for that split.
 
-What pins this behavior:
+## Verification
 
-- 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.
-- `$on`'s disposer belongs to the calling fiber, and two registrations of one function object retire independently — a table keyed on listener identity would collapse them, so subscriptions are addressed by registration.
-- Delivery contains a listener that throws AND one that rejects a returned promise: the declared return is `void`, so nobody awaits an async listener, and its rejection would otherwise escape this containment entirely. Delivery iterates a snapshot, so subscribing or disposing mid-frame cannot change who receives that frame.
-- `assertJsonArgs` is unit-tested directly rather than by driving a malformed emit through the event bus: a typed `ctx.emit` cannot construct one, since every allowlisted event has a statically JSON-safe payload.
-- The five dedicated `HostFrame` variants, five Client-side aliases, and their bridge branches are absent. The model directories observe both owner inputs, while command, skill, and session-row consumers observe the preset owner's committed-selection event.
+- A real Host-source composition test proves that two Client streams each receive `{ event, args }`, disconnecting one does not affect the other, and non-JSON arguments fail loudly without poisoning later valid delivery.
+- Type negatives reject unselected events, non-`void` unscoped events, non-Agent-scoped waterfalls, and allowlist modes that disagree with signatures. `$on('slots/changed', …)` and `$on('skills/change', …)` both fail to compile, so `$on`'s key set equals the allowlist.
+- Consumer `$on('settings/document-updated', …)` resolves `ns` as `SettingsNamespace`, preserving the brand across the wire.
+- A `$on` disposer belongs to the calling fiber, and registering the same function object twice produces independently removable registrations; subscriptions are addressed by registration rather than listener identity.
+- Ordinary notifications contain both a throwing listener and a listener returning a rejected Promise. Waterfall tests pin Client result, `next()`, rejection, cancellation, first claim across multiple Clients, and reconnect replay of a pending request.
+- Gateway tests cover missing, duplicate, and withdrawn sources; payload rejection; ready-before-event ordering; and browser and in-process carriers. Client tests cover generation-source registration, description/increment readiness order, reopen after physical failure, Host errors and unexpected completion, non-ready opening items, malformed event items, `$events/result` failure, and disposal quiescence.
+- `host/remote-event`, public `$dispatch`, the Client Runtime bridge, and API Proxy's allowlist dependency are absent; consumers observe owner events directly.
 
 ## 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.$on`), and no replay on reconnect — these are pure invalidation signals, and `connection/reset` already covers refetching after a reconnect. The mux stream's session events, answerable frames, and snapshot baselines stay out of scope.
-- **Client packages remain in the Host graph.** Twelve projects (`connection`, `runtime`, `ui-slots`, and kin) still reach it through the unsplit `directory-picker-browse`/`-native` pair and `api/gateway → client/connection`. They compile and no longer implicate api/remotes' Client face, so they did not block this change; splitting those packages would remove a few but was assessed and declined. The two chat e2e importing `dsh-client-runtime/client` rely on `runtime` already being in that graph — incidental, not a guarantee.
-- **The invariant companion holds no runtime check.** An earlier revision asserted the dispatch shape (`thisArg === null`, `mode === 'emit'`) over the live event bus, which coupled the companion to the allowlist value and made rolldown hoist it into a third bundle chunk the mechanical publication list does not carry. The Host face's `TypertForwardableEvent` assertion already refuses both deviations at compile time, so the companion is an explained empty installer.
+- **Gateway has one non-generated endpoint.** `$events` has no business namespace and does not enter the Typert descriptor. It is the internal connection point between Gateway and API Remotes and defines the Client Connection generation lifetime. Strict empty-payload validation, opening-ready validation, and single-source registration prevent it from becoming another handwritten business API.
+- **Two files break API Remotes' face-disjointness rule.** `src/remote-events.ts` and `src/types.ts` belong to both projects and emit identical declarations into shared `lib/types`. Their content is byte-identical and `.tsbuildinfo` files remain separate, so this is safe in practice; the README records why source-plane `paths` require the exception.
+- **Producer operations remain private.** Business plugins can call only `$on`. Host-source registration and Client dispatch are absent from `TypertClientRemote`; test doubles drive subscriptions through their own `emit` operations rather than impersonating a production API.
+- **Malformed arguments fail at emit.** An API Remotes listener throws before queueing, so Host `ctx.emit` immediately observes an allowlist composition error and the queue can still deliver subsequent valid events.
+- **Test-side mirrors can drift.** No mechanism compares mirrored Client constants under `apps/web/tests` with their source. Drift instead produces a selector mismatch. `apps/web/tests/README.md` records the review rule; a grep-level gate is deliberately omitted.
+- **Capabilities deliberately omitted.** Payload projection and redaction are unsupported, scopes other than Agent are unsupported, and ordinary notifications are not replayed. Recoverable state needs a query, cursor, or opening baseline; a waterfall is replayed only while its original Host invocation remains pending.
+- **Some Client packages remain in the Host graph.** Twelve projects, including `connection`, `runtime`, and `ui-slots`, remain reachable through unsplit `directory-picker-browse`/`-native` and `api/gateway → client/connection`. They compile and no longer pull in API Remotes' Client face, so this change does not split them. Direct `dsh-client-runtime/client` imports in two chat e2e files rely on Runtime's current presence in that graph rather than a general guarantee.
+- **The invariant companion intentionally has no runtime check.** A prior revision asserted delivery form on the live event bus, coupling the companion to the allowlist and causing Rolldown to emit a third bundle chunk omitted by the mechanically derived publication list. The Host-face `TypertForwardableEventEntry` assertion already rejects those mismatches at compile time, so the companion is an explained empty installer.

+**契约只公开消费动词。**`ClientRemoteService` 激活时就把内部唯一的 `$events` pump 注册为 Connection generation source，与当前有无 `$on` 订阅无关；浏览器通过共享 Remote mux 打开 `$events`，进程内组合通过 `connection.rpc.open` 打开同一 logical stream。解码、精确 item 校验和订阅表派发都是 Gateway Client 的私有实现，`TypertClientRemote` 不暴露生产方方法，因此业务插件不能伪造一条 Host 事件。

+每次 Host 打开 `$events` 时，API Remotes source factory 先同步挂载所有 allowlist listener，Gateway 随后产出首项 `{ type: 'ready' }`，再开始迭代事件 source。`ConnectionController` 并行等待该 ready 与 `host.describe`，只有两者都成功才发布 `connected` 并允许 baseline 读取。这个顺序保证 baseline 不会跑在增量 listener 前面。

-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）。
+Client 以 Remote 实例私有 Cordis key 分发。普通 `emit` 使用 `parallel()` 并隔离 listener 失败；Agent-scoped `waterfall` 在解析出的 Agent Context 上使用 `waterfall()`，允许结果、拒绝或 `next()` 委托。两类注册都归属调用方 fiber，且 Host 事件不会触发 Client 本地同名事件。

-**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。
+**继续寄生 API Proxy 的 Host downlink。**这样可以复用 Connection generation 和 `connection/reset`，但会让 API Proxy 保留 Remote 事件 allowlist、队列、schema 和 Client Runtime bridge，领域传输也无法随其他 Remote stream 共用生命周期。API Gateway 已有常驻 `/api/remote.mux` 后，`$events` 只增加一个 internal logical stream，不需要第三条 WebSocket，因此转移到 Gateway 的成本和所有权都更合理。
+
+**给 Remote 事件另开第三条物理 WebSocket 或 duplex stream。**独立通道能拥有自己的连接状态，但会重复 Gateway mux 已经提供的认证升级、复用、取消、错误映射和退避重连。内部 `$events` endpoint 保留独立 logical stream，waterfall 结果复用 HTTP 一元调用。
 
 **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。

-- 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 `$on` 的键面恰好等于名单。
+- Host source 真组合测试：两个 Client stream 各自收到 host emit 的 `{ event, args }`，其中一个断开不会影响另一个；非 JSON 实参会响亮拒绝且不会毒化后续合法事件。
+- 类型层负例拒绝未选择事件、非 `void` 的无 scope 事件、非 Agent-scoped waterfall，以及声明 mode 与签名不符的条目。`$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。
+- 普通通知同时收容抛出的 listener 与拒绝所返回 Promise 的 listener；waterfall 测试固定 Client result、`next()`、拒绝、取消、多 Client 首个 claim 和重连重放 pending request。
+- Gateway 测试覆盖 source 缺失、重复注册、撤销中止、payload 拒绝、ready 先于事件，以及浏览器与进程内两种 carrier；Client 测试覆盖 generation source 注册边界、描述与增量就绪顺序、物理失败后重开、Host 错误与意外结束、非 ready 首项、畸形事件项、`$events/result` 失败和 dispose quiescence。
+- `host/remote-event`、公开 `$dispatch`、Client Runtime bridge 和 API Proxy 的 allowlist 依赖都不存在；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。
+- **Gateway 有一个非生成 endpoint**：`$events` 不对应业务 namespace，也不进入 Typert descriptor；它是 Gateway 与 `api/remotes` 之间的内部连接点，同时定义 Client Connection generation 的存活期。严格的空 payload 校验、opening ready 校验和单 source 注册限制它不会演化成第二个手写业务 API。
 - **两个文件打破了 api/remotes 的 face 互斥约定**：`src/remote-events.ts` 与 `src/types.ts` 同属两个工程，各自向共享的 `lib/types` 发射一份相同声明。内容逐字节相同、`.tsbuildinfo` 各自独立，实践上无害；README 的构建边界节陈述了这个例外及其成因（`paths` 指向源码面）。
-- **载体交接是开发者可见的**：任何持有 `ctx.remote` 的 client 插件都能调 `$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 `$on` 的转换」，不假装该端口鉴别调用方。
-- **畸形实参在发射方的收容里失败，而非加载期**：`assertJsonArgs` 在转发监听内抛出，因此由发射 seam 自己的 listener 收容记录并丢弃该帧——响亮地出现在 host 日志里，而不是加载时或 emit 点。
+- **生产方保持私有**：业务插件只能调用 `$on`；Host source 注册和 Client 派发都不在 `TypertClientRemote` 上暴露，测试 double 以自己的 `emit` 方法驱动订阅，不伪装成生产接口。
+- **畸形实参在 emit 点失败**：`api/remotes` listener 在入队前抛出，因此调用 Host `ctx.emit` 的操作立即看到名单配置错误；队列仍可继续投递后续合法事件。
 - **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。
+- **放弃的能力**：不支持投影或脱敏载荷，不支持 Agent 以外的 Scope，也不为普通通知提供重放。需要可靠恢复的状态必须拥有查询、cursor 或 opening baseline；waterfall 只重放仍处于同一次 Host 调用生命周期内的 pending request。
 - **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: Session history, control state, and Remote event transport
+
+Status: implemented
+
+English | [中文](2026-08-18-session-history-and-event-transport.zh.md)
+
+## Problem
+
+The browser consumes three kinds of data with different lifecycles: persistable, paginated Session logs; process-local state that needs an opening baseline to converge after reconnect; and immediate notifications that need no replay.
+
+These kinds of data cannot share one recovery rule. Session logs have stable sequence numbers and persistence, so a cursor can fill gaps; queue, jobs, and Workspace lists need a complete snapshot to replace an old mirror; ordinary notifications only promise delivery within the current Connection generation.
+
+Observing Session history, lists, and projections must allow cold reads. If transport performs a general Typert lookup whenever an argument contains a Session or Agent, opening a page, switching tabs, or reconnecting the network implicitly resumes an Agent, so observation gains execution side effects.
+
+Commands such as prompt, create, fork, and model selection do need to create or resume an Agent according to their own semantics. Activation authority must belong to each Remote method, not be decided implicitly by the carrier, parameter types, or a shared lookup.
+
+The legacy API Proxy all-Session mux, `HostFrame`, and Workspace notifications encode domain data, baselines, errors, and connection lifecycle in one handwritten protocol. Each additional state duplicates frame declarations, a Client bridge, reconnect handling, and cleanup logic, while API Proxy cannot return to owning only business methods that have not yet migrated.
+
+Host-to-Client Cordis events also have two invocation modes. Ordinary notifications only need broadcast delivery; Agent-scoped waterfalls such as Approval and Question must let a Client claim, delegate through `next()`, return a result, or reject while preserving one Host invocation identity across multiple Clients, disconnects, and cancellation.
+
+These requirements need one general transport lifecycle without making Gateway understand Session, Workspace, Approval, or Question business data.
+
+## Decision
+
+API Gateway owns Remote transport, stream lifecycles, and Remote Event coordination. Session Controller and Workspace Controller own their Host APIs, wire types, and Client domain adapters. Client Runtime only composes and consumes these objects; it does not implement another carrier state machine.
+
+Current ownership is:
+
+```text
+[client/connection]
+|-- Host description
+|-- Connection generation
+`-- unary RPC transport
+
+[api/gateway/client]
+|-- RemoteStream
+|-- RemoteSnapshotStream
+|-- RemoteJournalStream
+`-- ctx.remote.$on + $events pump
+
+[api/session-controller]
+|-- ctx.remote.session unary commands
+|-- session.control snapshot stream
+|-- session.page + session.follow journal
+`-- Session Client adapters
+
+[api/workspace-controller]
+|-- ctx.remote.workspace unary commands
+|-- workspace.follow snapshot stream
+`-- Workspace Client model and adapter
+
+[api/remotes]
+`-- application Remote Event allowlist and Host Cordis source
+
+[client/runtime]
+`-- compose Session and Workspace domain state for consumers
+```
+
+API Proxy owns neither the Session or Workspace Remote namespace nor the Host downlink event carrier. `/api/events.host`, `HostFrame`, `stream/error`, `ServerRequest`, and their WebSocket/SSE branches do not participate in this data path.
+
+### Connection generation and physical connections
+
+The browser's Client Remote plugin starts `RemoteStreamMuxClient` idempotently on activation and connects to `/api/remote.mux` immediately. The physical WebSocket remains resident even when there is no business logical stream.
+
+After an initial connection failure or the loss of a connected socket, the mux rebuilds the physical connection with capped jittered backoff. Logical streams not yet opened share that reconnect loop; streams already open end their current physical generation with `RemoteStreamCarrierError`.
+
+In-process `connection.rpc.open` uses the same logical endpoint semantics while bypassing the browser WebSocket mux.
+
+The Gateway-internal `$events` logical stream is the sole generation source for `ConnectionHandle`. It does not depend on whether any business `$on` subscription exists, so connection health does not vary with the number of UI listeners.
+
+The Host event source installs incremental listeners synchronously before returning its first frame. Gateway then sends `{ type: 'ready' }` with a `clientId`; this frame proves that the current generation can receive increments.
+
+`ConnectionController` waits for `$events` readiness and `host.describe` in parallel. It publishes `connected` only after both complete, so a Session or Workspace baseline cannot be read before Host incremental listeners are ready.
+
+Unexpected normal completion of `$events`, a Host error, a malformed opening frame, or a carrier failure ends the current Connection generation. Connection withdraws `hostDescription`, then re-establishes `$events` and `host.describe` after backoff.
+
+Gateway stream generation, Connection generation, and a Session business open epoch are three independent counters: the first identifies physical replacement of one logical stream, the second identifies a Host-availability handshake, and the last prevents an obsolete Session open from writing into current state.
+
+Plugin disposal stops backoff, cancels candidate and active sockets, ends logical streams, and awaits quiescence of background loops and consumers.
+
+### General Remote stream model
+
+Gateway Client provides three React-independent, single-consumer lifecycle objects:
+
+```text
+RemoteStream<Item>
+|-- RemoteSnapshotStream<Snapshot, Delta>
+`-- RemoteJournalStream<Page, Entry, Cursor>
+```
+
+Domain Controllers use them through composition or thin adapters; Session and Workspace do not inherit a common Controller base class that knows domain frames.
+
+#### `RemoteStream`
+
+`ctx.remote.$stream(options)` returns a `RemoteStream<Item>` responsible for reopening, cancellation, and disposal of one logical stream across physical generations.
+
+Each item carries a monotonic generation, that generation's `AbortSignal`, and `accept()`. A domain consumer calls `accept()` only after validating the opening cursor or baseline.
+
+Only `RemoteStreamCarrierError` permits retry. When the Host remains available, one independent reopen is allowed; otherwise the stream waits for a new Connection generation. Business errors, protocol errors, and opening failures terminate immediately.
+
+`restart()` replaces only the current physical generation and preserves the logical stream. `dispose()` permanently ends the logical stream, pending retry, and iterator, then waits for quiescence.
+
+`RemoteStream` does not understand baselines, deltas, pages, cursors, sequence numbers, or any domain frame.
+
+#### `RemoteSnapshotStream`
+
+`RemoteSnapshotStream<Snapshot, Delta>` requires each generation to start with exactly one complete snapshot, followed only by deltas.
+
+An update before the snapshot or a second snapshot in the same generation is a terminal protocol error.
+
+The generation is accepted only after its snapshot has been applied successfully. The previously published state remains readable while the carrier reconnects, and the new generation's snapshot replaces the old mirror atomically.
+
+The domain adapter supplies frame discrimination, snapshot replacement, a delta reducer, carrier state, and a terminal failure sink. The general layer parses no Session or Workspace fields.
+
+Session control and Workspace state each use an independent `RemoteSnapshotStream`.
+
+#### `RemoteJournalStream`
+
+`RemoteJournalStream<Page, Entry, Cursor>` combines one live follow with a page method in the same namespace. It applies to an append-only journal with a stable order, paginated history, and a live tail.
+
+Initial opening establishes follow and obtains its opening cursor before reading the initial page. Live entries produced while the page request is pending already enter the follow queue, closing the race between reading history and subscribing afterward.
+
+The general layer removes overlap between the page and queued entries by cursor, verifies continuity, and publishes one complete window after the page covers the opening cursor.
+
+Contiguous live entries publish `append`; older history pages publish `prepend`. Reconnect, cursor jumps, or continuity that cannot be proven trigger a tail-page repair.
+
+The old window remains readable during repair. The page and live entries accumulated during that read form a continuous window and publish one `replace`, never exposing a half-repaired state.
+
+If a page request is canceled with its physical carrier generation, the journal waits for the next generation's opening cursor and rereads the page at that cursor. This cancellation does not leak to the domain object as a terminal page failure.
+
+`RemoteJournalStream` owns the opening cursor, resume cursor, pagination, reconnect catch-up, overlap removal, and gap repair. A domain Session object does not copy these state machines.
+
+### Session Controller
+
+`packages/api/session-controller` provides Host `ctx.sessionController` and the generated `ctx.remote.session` namespace.
+
+It owns Session list, search, create, models, selectModel, rename, fork, prompt, attachment, updateQueue, cancel, page, follow, and control.
+
+The package separates agent, commands, control, history, and list controllers internally, but Session identity resolution, activation policy, subagent ownership, and Remote error projection have one public owner.
+
+Other Host Remote namespaces reuse the same identity rules through `ctx.sessionController.inspect()` or `resolveAgent()`; they do not retain a second Session resolver.
+
+#### Activation policy
+
+Session Remote methods pass `SessionId` or `SessionAddress`; parameter types do not trigger a general Typert Session lookup.
+
+Each method explicitly selects a cold inspection, live-only lookup, or resume-capable resolution:
+
+| Operation | Source or result without a live Agent | Activation rule |
+|---|---|---|
+| `session.list`, `search` | persistence, projection cache, or cold log | Never resumes an Agent |
+| `session.page(address)` | attached Session or persistence log | Never resumes an Agent |
+| `session.follow(address)` | cold-read current cursor, then wait for future appends | Neither opening nor waiting resumes an Agent |
+| `session.control()` | current attached Agents, pending registry, and process-local registries | Baseline and reconnect do not resume an Agent |
+| `session.attachment`, fork source read | authorized durable Session data | A read does not resume an Agent |
+| `session.updateQueue`, `cancel` | only the current live Agent | Does not resume vanished state |
+| `models`, `selectModel`, `rename`, `prompt` | command resolves the target Session | Resumes only when the method explicitly permits it |
+| `create` and fork target | new Session/Agent | The user command supplies creation authority |
+
+Reading titles, lists, and projections does not require an Agent. An observation operation cannot inherit resume authority merely because another Remote endpoint uses Agent lookup.
+
+#### Session journal
+
+`session.page` returns a history window clipped on message boundaries with contiguous internal sequence numbers. Every request must carry an explicit `throughSeq`; this value comes from the corresponding `session.follow` generation's opening cursor and fixes the read at the same log cut. A tail page without `beforeSeq` must end exactly at `throughSeq`, where `-1` denotes an empty log. `beforeSeq` only selects an older page before that cut and cannot replace the synchronization cursor. `maxMessages` limits user/assistant message count without dropping chunks, tools, or state events between those messages.
+
+The tail page also carries a projection baseline no later than `throughSeq`; older pages carry only historical entries. The Client merges pages and subsequent live control updates by projection watermark.
+
+Ordinary Sessions and direct subagents use one `SessionAddress` protocol. A direct-subagent address carries parent Session, child Session, and mode; a cold Host read verifies durable ownership and descriptor rather than authorizing access from the child id alone.
+
+`session.follow` installs `session/event` and `session/created` listeners before checking an attached Session or persistence, then reads the current cursor.
+
+The first follow response is `{ type: 'opened', cursor }`. A generation with `afterSeq` first replays the missing suffix from the authoritative log, then emits commits buffered during the read in sequence order.
+
+A cold Session can open history immediately and keep follow waiting. Future events appear only after another explicit command resumes the Agent.
+
+Client `SessionEventStream` extends `RemoteJournalStream` and supplies only `session.follow`, `session.page`, the Session sequence algorithm, and repair requests. The general layer first obtains opening cursor `C`, then calls `session.page({ throughSeq: C })`; entries `C + 1...` received during the read remain in the follow queue, and the page must cover exactly through `C` before the layer merges and publishes a continuous sequence.
+
+```text
+ctx.remote.session.follow(address, afterSeq?) --------|
+                                                       |[]> SessionEventStream
+ctx.remote.session.page(address, throughSeq, pageArgs) -|    |-- replace(window)
+                                                            |-- prepend(history)
+                                                            `-- append(live entry)
+```
+
+Each Client Session owns only one current `events: SessionEventStream | undefined`. The read-only `SessionEventSource` gives the materialized event window to Conversation consumers.
+
+A Session's `openGeneration` only prevents an asynchronous result retired by resync, address replacement, or disposal from writing into current state. It does not participate in transport retry.
+
+A terminal failure from the initial page, repair page, or follow enters the current Session's `openError`. A stale business epoch or stale stream cannot overwrite newer state.
+
+#### Session live control
+
+`session.control()` is a Host-wide snapshot stream. One browser can observe transient state for all current live Sessions without opening a journal for every transcript.
+
+Each generation emits a complete baseline first, followed by queue, jobs, and projection deltas. The baseline reads attached Agents and process-local registries without resuming cold Agents.
+
+Queue and jobs use complete replacement values and apply last-wins. Agent attach, detach, Session disposal, and owner disposal can all clear a stale mirror through an empty value or a new baseline.
+
+The original `approval/request` and `user-questions/request` events are forwardable waterfalls. If an Agent-scoped Client listener claims a request, it returns directly. If all delivered Clients call `next()`, the original Cordis waterfall continues to later Host listeners. Session control neither stores nor replays these requests.
+
+The projection baseline and a tail page's log cut are produced independently. The Client always retains the value with the higher sequence number. Subscribing to live projection does not start an Agent merely to obtain a value.
+
+Session added, removed, activity, running status, and Agent error without a turn position do not enter the stateful control stream; they are `ctx.remote.$on` notifications that are either repairable from a list baseline or need no replay.
+
+Session-list `updatedAt` is `max(header.createdAt, sessionListMetadata.lastPromptAt)`. Only a user-originated `user/message` updates `lastPromptAt`; it can be recovered from a cold projection and does not depend on whether a browser follows that Session.
+
+### Workspace Controller
+
+`packages/api/workspace-controller` provides Host `ctx.workspaceController` and the generated `ctx.remote.workspace` namespace.
+
+It owns create, rename, delete, insertBefore, insertSessionBefore, archiveSession, and `follow`. Workspace registry remains the durable source of truth; the Controller owns Remote commands, projection, and error mapping.
+
+`WorkspaceFeed` synchronously observes storage `domain/changed`, and each follow generation emits a complete baseline before `upsert`, `remove`, `order`, and `archived` deltas.
+
+A complete `order` frame is authoritative for Workspace ordering. It avoids having the Client infer display order from upsert arrival order and converges after a reconnect baseline.
+
+`createWorkspaceStateStream()` assembles `workspace.follow` as a `RemoteSnapshotStream`. Client Runtime only starts and owns that stream.
+
+`ClientWorkspaceModel` lives on Workspace Controller's Client face. It owns baseline/increment parsing, the materialized list, the archived set, command-result echo, and merge rules for races between unary and stream arrivals.
+
+A successful unary command can update the local model immediately; a later stream commit still corrects state with the Host projection and complete order. Deleted Workspace ids are recorded so a delayed result cannot reinsert them.
+
+```text
+ctx.remote.workspace.follow() -|[]> RemoteSnapshotStream
+                                      |-- replace(baseline)
+                                      |-- upsert/remove(view)
+                                      |-- replace(order)
+                                      `-- replace(archived ids)
+```
+
+Workspace Remote methods, state feed, and Client data model do not pass through API Proxy or depend on `host/workspace-*` notifications.
+
+### Remote Event
+
+Remote Event reuses owner packages' Cordis `Events` declarations. The original Host event is the sole business signature, and Client `ctx.remote.$on(event, listener)` derives its parameters, waterfall result, and `next()` from that declaration.
+
+The allowlist in `packages/api/remotes` is the sole source of application selection. Each entry explicitly marks `emit` or `waterfall`; this mode determines Host listening, the legal Client key set, and the wire frame type together.
+
+The system declares no `RemoteInvocationMap`, requires no second Client `@Remote`, and does not infer invocation mode by checking whether the final runtime argument is a function.
+
+Remote Event downlink frames form an explicit discriminated union:
+
+```text
+ready     { type, clientId }
+emit      { type, event, args }
+waterfall { type, event, eventId, agentId, request }
+cancel    { type, eventId }
+```
+
+Both WebSocket JSON and in-process carrier entry points start from `unknown` and validate the discriminant plus exact fields. Dispatch after validation accepts only the typed union. TypeScript static types do not replace wire validation.
+
+Ordinary `emit` arguments must be lossless JSON. The Client calls `parallel()` on a Cordis key private to each Remote instance, preserving registration order, calling-fiber ownership, and listener-error isolation.
+
+The private key prevents Host events and same-named Client-local Cordis events from triggering one another. Client Remote maintains neither its own subscription registry nor a handwritten listener chain.
+
+Returning waterfalls currently support Agent scope only. The event signature must contain one request with a direct `agent` field followed by a `next()` returning the same result type, and the whole event returns a Promise.
+
+The Host projects only top-level `agent` and `signal` fields from the request: `agent` becomes top-level `agentId` in the frame, `signal` becomes the delivery lifetime, and all remaining fields must be lossless JSON as a whole.
+
+The Client synchronously resolves or materializes an Agent Context from `agentId`, restores the current delivery signal into the request's direct `signal` field, and invokes Cordis `waterfall()` on the target Context's private key. Before the first successful Session-list baseline, the Session-backed adapter lets transport materialize a scope; after that baseline, the list lifecycle owns scope liveness.
+
+The system does not scan arbitrarily deep objects, transmit path arrays or placeholders, deep-clone/restore Context and AbortSignal, or wait for a future Agent Context.
+
+When no Client adapter is registered, its resolver returns no Context, or resolution throws, that Client immediately returns `next`. It does not subscribe to a registry, recheck races after resolution, or create a temporary Fiber for one delivery.
+
+Gateway Host retains `eventId`, the Host continuation, and delivered Client generations for every unfinished waterfall. A new Client generation receives a replay of the same pending event.
+
+Each generation's queue guarantees one delivery, so the Client stores no `seen` set. `clientId + eventId` binds a result to the current generation; a reply from an old connection cannot complete delivery on a new one.
+
+When several Clients receive a waterfall, the first result or rejection completes the Host invocation and sends `cancel` to the other Clients. Gateway continues the original Cordis chain only after every delivered Client returns `next`.
+
+Host caller-signal cancellation, Agent Context disposal, Client-generation completion, and losing-Client cancellation all terminate their corresponding waits.
+
+The Client returns `next`, result, or rejection through the existing HTTP unary RPC `$events/result`; downlink events continue to share the Remote WebSocket mux, with no duplex WebSocket for responses.
+
+Gateway only verifies that a waterfall return value has a lossless JSON representation; it does not interpret business fields. Semantics such as whether a Question answer belongs to an offered option remain owned by the requester or UI domain and are not revalidated by transport.
+
+When `UserQuestionService` observes that the caller's `AbortSignal` was canceled during a request and the provider threw an ordinary error, it normalizes that failure to `UserQuestionError` with `ASK_ABORTED` while retaining the original error as `cause`. A domain error already supplied by the provider preserves its identity.
+
+A failure of `$events/result` fails the current Connection generation. Host withdraws that Client's delivery with the generation, the pending event is replayed in the next generation, and Client maintains no second result-retry queue.
+
+Ordinary `$on` notifications are not replayed after disconnect. State whose correctness depends on recovery must have a query, cursor, or opening baseline and cannot rely on eventual Remote Event delivery.
+
+An event is not replayed when its Client listener registers after arrival. HMR has no dedicated redelivery semantics.
+
+### API Proxy's remaining boundary
+
+Session Controller and Workspace Controller provide generated Remote namespaces directly; API Remotes and API Gateway provide Host-to-Client events directly.
+
+Client Connection maintains only Host generation, description, and generic RPC. It does not parse domain frames.
+
+Client Runtime only receives domain changes produced by Controller adapters. It recognizes no `HostFrame`, `session/subscribed`, `session/event` mux frame, or `host/workspace-*` frame.
+
+API Proxy carries only independent business APIs it owns. Session, Workspace, Remote Event, and Connection generation do not depend on it.
+
+## Alternatives considered
+
+**Resume an Agent whenever any Session stream opens.** Viewing history, reading a title, reconnecting a tab, or observing background state would gain execution side effects, and multiple browsers could trigger duplicate resumes. Cold logs and projections already have persistence sources.
+
+**Permit `session.follow` only for live Agents.** The first transcript render would have to resume an Agent or reintroduce the race between unary history and live subscription. Following by identity before a cold read covers both history and future explicit activation.
+
+**Split Session transport and Session commands into two public packages.** Both depend on Session address, Agent activation policy, subagent ownership, error mapping, and Client mount ordering. One public Controller preserves unified ownership while internal classes can evolve independently.
+
+**Move queue, jobs, projection, Workspace, and logs to ordinary `$on`.** Ordinary events have no reconnect baseline, cursor, or gap repair, so one missed delivery leaves permanently stale state. Only notifications that need no recovery, can be repaired by an independent query, or carry their own lifetime as a waterfall fit `$on`.
+
+**Make every domain Controller inherit a page/follow/retry base class.** Session journals and Workspace snapshots have different opening, recovery, and ordering rules. Gateway's three compositional stream objects reuse transport lifecycle while domain adapters declare only their own frame semantics.
+
+**Declare a separate Client invocation map for Remote Event.** A second map or Client `@Remote` would copy owner Cordis event signatures and create a drift point. Deriving `$on` listeners and results from the same `Events` declaration preserves equivalence by construction.
+
+**Project Agent scope through arbitrary object depth.** Recursive Context and AbortSignal scans need path, placeholder, clone, and restore protocols and turn incidental object structure into a wire promise. Top-level `agent` and `signal` cover current waterfalls.
+
+**Wait for a Client Agent Context or adapter before dispatching.** Registry waiters, post-resolution race checks, and temporary delivery Fibers add lifecycle to a Client that can synchronously resolve or materialize its target. Returning `next` when the resolver cannot provide a target immediately preserves Cordis waterfall semantics.
+
+**Use an independent physical WebSocket or duplex stream for Remote Event.** Gateway mux already provides authenticated upgrade, multiplexing, cancellation, error mapping, and reconnect. Downlink `$events` plus HTTP `$events/result` expresses request/response without a third connection.
+
+**Retain API Proxy's Host mux.** This keeps the handwritten union, schema, response envelope, and second stream lifecycle, and prevents Session and Workspace Controllers from owning their data protocols independently.
+
+**Update Session list time from aggregate `session/event`.** List correctness would depend on which Sessions a browser consumes and would mistake arbitrary plugin events for user activity. The durable `lastPromptAt` projection expresses the ordering fact directly.
+
+## Verification
+
+Gateway mux tests pin connection without logical streams, idle residency, initial-failure and disconnect recovery, active-stream carrier failure, cancellation, and no reconnect after disposal.
+
+Connection tests pin missing, duplicate, and withdrawn generation sources; the race between `$events` ready and `host.describe`; and description withdrawal and rebuilding after generation failure.
+
+`RemoteStream` tests pin single consumption, retry reset after opening acceptance, generation-only `restart()`, no retry for terminal errors, and disposal quiescence.
+
+`RemoteSnapshotStream` tests pin exactly one opening snapshot per generation, rejection of an update before a snapshot, rejection of duplicate snapshots, and reconnect replacement.
+
+`RemoteJournalStream` tests pin follow-before-page, opening-overlap removal, contiguous append, historical prepend, reconnect catch-up, gap repair, and one atomic replacement.
+
+Session Host tests pin cold page/follow without increasing attached Agents, contiguous events reaching a cold follow after an explicit prompt, direct-subagent ownership, message-aligned pagination, and terminal-error projection.
+
+Session control tests pin baseline-first delivery, no cold-Session resume, attach/detach cleanup, queue and jobs replacement, and the projection watermark.
+
+Session Client tests pin one journal owner per Session, no writeback from stale open epochs, independent cancellation of control and journal, and retaining the published window during carrier retry.
+
+Workspace Host tests pin baseline-first delivery, upsert/remove, authoritative order, archived set, and follower disposal.
+
+Workspace Client tests pin snapshot replacement, unary/stream races, no resurrection after delete, stable ordering, and terminal failure.
+
+Remote Event type tests reject unselected events, non-void unscoped events, non-Agent-scoped waterfalls, and modes that disagree with signatures.
+
+Remote Event Host tests pin listener-before-ready, payload validation, pending replay, first result across multiple Clients, all-next delegation, rejection, Host cancellation, Context release, and losing-Client cancellation.
+
+Remote Event Client tests pin instance-private keys, Cordis registration order, Agent Context resolution, `next`, result, rejection, cancellation, rejection of stale-generation replies, and Connection-generation failure when `$events/result` fails. User Question tests pin normalization of in-progress signal cancellation and preservation of its cause.
+
+Missing, duplicate, and withdrawn sources; non-ready first items; unknown discriminants; extra fields; and non-JSON values all fail loudly at their respective wire entries.
+
+Static checks pin that API Proxy exports no Session/Workspace Host-frame carrier and Client Runtime contains no corresponding bridge.
+
+## Consequences
+
+The browser can read and follow a durable Session while its Agent is stopped. Observation does not implicitly resume execution; only explicitly authorized Session commands create or resume Agents according to their own rules.
+
+Durable logs repair a missing suffix by sequence number and page; Session control and Workspace state converge through opening snapshots; ordinary Remote Events promise no replay. Recovery semantics follow the data kind instead of imitating one another.
+
+Gateway owns only transport, generation, pending waterfalls, and strict wire validation, not Session or Workspace business fields. A domain Controller supplies only openers, cursor rules, baseline reducers, and error presentation.
+
+Session and Workspace Host APIs, stream adapters, and Client data models each have an explicit owner. API Proxy is no longer their intermediary.
+
+The general stream objects add three explicit layers while deleting the retry, cancellation, generation, baseline, and gap-repair shells previously duplicated by each Controller.
+
+Remote waterfalls preserve first claim across multiple Clients, continuation of the Host chain after every Client calls `next`, reconnect replay of pending calls, and end-to-end cancellation. The current protocol supports only top-level Agent scope and lossless-JSON requests and results.
+
+This decision extends the allowlist and single Cordis-signature design from [Remote event delivery](2026-08-10-remote-event-delivery.md): ordinary notifications use `emit`, while Agent-scoped async waterfalls use the same `ctx.remote.$on` surface with explicit `waterfall` mode. It creates no second invocation map.
+
+This decision takes over the Session, Workspace, and Host-event carriers retained by [simple unary API Proxy migration](../../proposed/architecture/2026-08-10-unary-apiproxy-remote-migration.md) while preserving the complete jobs snapshot, process-local lifecycle, and “observation does not resume an Agent” semantics required by [background job display](../feature/2026-08-08-web-background-job-display.md).

+
+## 问题
+
+浏览器同时消费三类生命周期不同的数据：可持久化并分页的 Session 日志、需要 opening baseline 才能在重连后收敛的进程内状态，以及无需重放的即时通知。
+
+这三类数据不能共用一种恢复规则。Session 日志有稳定 seq 和 persistence，可以按 cursor 补齐缺口；queue、jobs、Workspace 列表等状态需要以完整 snapshot 替换旧镜像；普通通知只保证当前 Connection generation 内投递。
+
+观察 Session 历史、列表和投影必须允许冷读取。若 transport 因参数中出现 Session 或 Agent 就触发通用 Typert lookup，打开页面、切换标签或网络重连都会隐式恢复 Agent，观察操作因此产生执行副作用。
+
+prompt、create、fork、模型选择等命令又确实需要按各自语义创建或恢复 Agent。激活权限必须属于具体 Remote 方法，而不能由 carrier、参数类型或共享 lookup 暗中决定。
+
+旧 API Proxy 的全 Session mux、`HostFrame` 与 Workspace 通知把领域数据、baseline、错误和连接生命周期编码进同一手写协议。每增加一种状态都要复制帧定义、Client bridge、重连和清理逻辑，API Proxy 也无法退回只承接尚未迁移的业务方法。
+
+Host 向 Client 的 Cordis 事件还有两种调用语义。普通通知只需要广播；Approval 与 Question 一类 Agent-scoped waterfall 必须允许 Client claim、调用 `next()` 委托、返回结果或拒绝，并在多 Client、断线和取消下保持一次 Host 调用的身份。
+
+这些需求需要一个通用 transport 生命周期，但不能让 Gateway 理解 Session、Workspace、Approval 或 Question 的业务数据。
+
+## 决定
+
+API Gateway 拥有 Remote transport、stream 生命周期和 Remote Event 协调；Session Controller 与 Workspace Controller 拥有各自的 Host API、wire 类型和 Client 领域 adapter；Client Runtime 只装配并消费这些对象，不再实现另一套 carrier 状态机。
+
+当前所有权如下：
+
+```text
+[client/connection]
+|-- Host description
+|-- Connection generation
+`-- unary RPC transport
+
+[api/gateway/client]
+|-- RemoteStream
+|-- RemoteSnapshotStream
+|-- RemoteJournalStream
+`-- ctx.remote.$on + $events pump
+
+[api/session-controller]
+|-- ctx.remote.session unary commands
+|-- session.control snapshot stream
+|-- session.page + session.follow journal
+`-- Session Client adapters
+
+[api/workspace-controller]
+|-- ctx.remote.workspace unary commands
+|-- workspace.follow snapshot stream
+`-- Workspace Client model and adapter
+
+[api/remotes]
+`-- application Remote Event allowlist and Host Cordis source
+
+[client/runtime]
+`-- compose Session and Workspace domain state for consumers
+```
+
+API Proxy 不拥有 Session 或 Workspace Remote namespace，也不拥有 Host 下行事件 carrier。`/api/events.host`、`HostFrame`、`stream/error`、`ServerRequest` 及其 WebSocket／SSE 分支不参与这条数据链路。
+
+### Connection generation 与物理连接
+
+浏览器的 Client Remote 插件激活时幂等启动 `RemoteStreamMuxClient`，并立即连接 `/api/remote.mux`。没有业务 logical stream 时物理 WebSocket 仍保持常驻。
+
+首次建连失败或已连接 socket 丢失后，mux 使用有上限的抖动退避重建物理连接。尚未打开的 logical stream 共享该重连循环；已经打开的 stream 以 `RemoteStreamCarrierError` 结束当前物理 generation。
+
+进程内 `connection.rpc.open` 使用同一 logical endpoint 语义，但绕过浏览器 WebSocket mux。
+
+Gateway 内部 `$events` logical stream 是 `ConnectionHandle` 唯一的 generation source。它不依赖是否已有业务 `$on` 订阅，因此连接健康状态不会随 UI listener 数量变化。
+
+Host event source 在返回首帧前同步安装增量 listener。Gateway 随后发送带 `clientId` 的 `{ type: 'ready' }`，该帧证明当前 generation 已经能够接收增量。
+
+`ConnectionController` 并行等待 `$events` ready 与 `host.describe`。两者都完成后才发布 `connected`，所以 Session 或 Workspace baseline 不会在 Host 增量 listener 就绪前开始读取。
+
+`$events` 正常意外结束、Host 错误、畸形首帧或 carrier 失败都会结束当前 Connection generation。Connection 撤回 `hostDescription`，退避后重新建立 `$events` 与 `host.describe`。
+
+Gateway stream、Connection generation 与 Session 业务 open epoch 是三个独立计数：前者表示某条 logical stream 的物理替换，第二个表示 Host 可用性握手，最后一个防止已淘汰的 Session open 写回当前状态。
+
+插件销毁会停止退避，取消候选与活动 socket，终止 logical stream，并等待后台循环和 consumer 静默退出。
+
+### 通用 Remote stream 模型
+
+Gateway Client 提供三个不依赖 React、只允许一个 consumer 的生命周期对象：
+
+```text
+RemoteStream<Item>
+|-- RemoteSnapshotStream<Snapshot, Delta>
+`-- RemoteJournalStream<Page, Entry, Cursor>
+```
+
+领域 Controller 通过组合或薄 adapter 使用它们；Session 与 Workspace 不继承一个知道领域帧的共同 Controller 基类。
+
+#### `RemoteStream`
+
+`ctx.remote.$stream(options)` 返回 `RemoteStream<Item>`，负责一个 logical stream 跨物理 generation 的重开、取消和 dispose。
+
+每个 item 携带单调 generation、该 generation 的 `AbortSignal` 与 `accept()`。领域 consumer 只有在验证 opening cursor 或 baseline 后才调用 `accept()`。
+
+只有 `RemoteStreamCarrierError` 可触发重试。Host 仍可用时允许一次独立重开；否则等待新的 Connection generation。业务错误、协议错误和 opening 失败直接终止。
+
+`restart()` 只淘汰当前物理 generation，保留 logical stream；`dispose()` 永久结束 logical stream、pending retry 与 iterator，并等待 quiescence。
+
+`RemoteStream` 不理解 baseline、delta、page、cursor、seq 或任何领域 frame。
+
+#### `RemoteSnapshotStream`
+
+`RemoteSnapshotStream<Snapshot, Delta>` 要求每个 generation 恰好以一份完整 snapshot 开始，之后只能出现 delta。
+
+update 早于 snapshot 或同 generation 出现第二份 snapshot 都是 terminal protocol error。
+
+snapshot 成功应用后才接受该 generation。carrier 重连期间保留上一份已发布状态，新 generation 的 snapshot 一次性替换旧镜像。
+
+领域 adapter 提供 frame 判别、snapshot replacement、delta reducer、carrier 状态和 terminal failure sink；通用层不解析 Session 或 Workspace 字段。
+
+Session control 与 Workspace state 各使用一个独立的 `RemoteSnapshotStream`。
+
+#### `RemoteJournalStream`
+
+`RemoteJournalStream<Page, Entry, Cursor>` 组合一个 live follow 与同 namespace 的 page 方法，适用于有稳定顺序、可分页历史和 live tail 的 append-only journal。
+
+首次打开先建立 follow 并取得 opening cursor，再读取 initial page。page 请求期间产生的 live entries 已进入 follow 队列，因此不会落在“先读历史、后订阅”的竞态窗口中。
+
+通用层按 cursor 去除 page 与 queued entries 的重叠，验证连续性，并在 page 覆盖 opening cursor 后发布一份完整 window。
+
+连续 live entry 发布 `append`，更早的历史页发布 `prepend`。重连、cursor 跳跃或无法证明连续性时触发 tail page repair。
+
+repair 期间旧 window 保持可读；page 与期间积累的 live entries 拼成连续窗口后只发布一次 `replace`，不会把半修复状态暴露给消费者。
+
+若 page 请求随物理 carrier generation 一起取消，journal 等待下一 generation 的 opening cursor，再以新 cursor 重读 page；该取消不会作为 terminal page failure 泄漏给领域对象。
+
+`RemoteJournalStream` 拥有 opening cursor、resume cursor、分页、重连 catch-up、重叠去重和 gap repair。领域 Session 对象不复制这些状态机。
+
+### Session Controller
+
+`packages/api/session-controller` 提供 Host `ctx.sessionController` 与生成的 `ctx.remote.session` namespace。
+
+它拥有 Session list、search、create、models、selectModel、rename、fork、prompt、attachment、updateQueue、cancel、page、follow 与 control。
+
+包内的 agent、commands、control、history 与 list controller 分开实现，但 Session 身份解析、激活策略、subagent ownership 和 Remote 错误投影只有一个公开 owner。
+
+其他 Host Remote namespace 通过 `ctx.sessionController.inspect()` 或 `resolveAgent()` 复用同一身份规则，不保留第二份 Session resolver。
+
+#### 激活策略
+
+Session Remote 方法传递 `SessionId` 或 `SessionAddress`，不靠参数类型触发通用 Typert Session lookup。
+
+每个方法显式选择冷检查、live-only 查找或允许 resume 的解析方式：
+
+| 操作 | 无 live Agent 时的数据来源或结果 | 激活规则 |
+|---|---|---|
+| `session.list`、`search` | persistence、投影缓存或冷日志 | 永不恢复 Agent |
+| `session.page(address)` | attached Session 或 persistence 日志 | 永不恢复 Agent |
+| `session.follow(address)` | 冷读当前 cursor，等待将来的 append | 建联和等待都不恢复 Agent |
+| `session.control()` | 当前 attached Agent、pending registry 与进程内 registry | baseline 与重连不恢复 Agent |
+| `session.attachment`、fork 源读取 | 已授权的持久 Session 数据 | 读取不恢复 Agent |
+| `session.updateQueue`、`cancel` | 仅命中当前 live Agent | 不为已消失状态恢复 Agent |
+| `models`、`selectModel`、`rename`、`prompt` | 命令解析目标 Session | 仅按方法约定显式恢复 |
+| `create` 与 fork 目标 | 新 Session／Agent | 用户命令提供创建授权 |
+
+读取 title、列表和投影不要求 Agent。观察操作不能因为另一个 Remote endpoint 使用了 Agent lookup 而继承其恢复权限。
+
+#### Session 日志
+
+`session.page` 返回一段按消息边界裁剪、内部 seq 连续的历史窗口。每个请求必须显式携带 `throughSeq`；该值来自对应 `session.follow` generation 的 opening cursor，并把本次读取固定在同一个日志切点。无 `beforeSeq` 的 tail page 必须精确结束于 `throughSeq`，其中 `-1` 表示空日志；`beforeSeq` 只选择该切点之前的更早页面，不能替代同步 cursor。`maxMessages` 限制 user／assistant 消息数，不丢弃这些消息之间的 chunk、tool 或状态事件。
+
+tail page 同时携带不晚于 `throughSeq` 的 projection baseline；旧页只携带历史 entries。Client 以 projection watermark 合并 page 与后续 live control 更新。
+
+普通 Session 与 direct subagent 使用同一个 `SessionAddress` 协议。direct subagent 地址同时携带父 Session、子 Session 与 mode，Host 冷读时验证持久 ownership 和 descriptor，不能只凭 child id 越权读取。
+
+`session.follow` 在检查 attached Session 或 persistence 前先安装 `session/event` 与 `session/created` listener，再读取当前 cursor。
+
+首次 follow 返回 `{ type: 'opened', cursor }`。带 `afterSeq` 的 generation 先从权威日志重放缺失后缀，再按 seq 排出读取期间缓存的 commit。
+
+冷 Session 可以立即打开历史并保持 follow 等待。只有另一条显式命令恢复 Agent 后，后续事件才会出现。
+
+Client 的 `SessionEventStream` 继承 `RemoteJournalStream`，只提供 `session.follow`、`session.page`、Session seq 算法与 repair request。通用层先取得 opening cursor `C`，再调用 `session.page({ throughSeq: C })`；读取期间收到的 `C + 1...` entries 留在 follow 队列中，page 精确覆盖至 `C` 后才按连续 seq 合并并发布。
+
+```text
+ctx.remote.session.follow(address, afterSeq?) --------|
+                                                       |[]> SessionEventStream
+ctx.remote.session.page(address, throughSeq, pageArgs) -|    |-- replace(window)
+                                                            |-- prepend(history)
+                                                            `-- append(live entry)
+```
+
+每个 Client Session 只持有一个当前 `events: SessionEventStream | undefined`。只读 `SessionEventSource` 把已物化 event window 交给 Conversation consumer。
+
+Session 的 `openGeneration` 只阻止被 resync、地址替换或 dispose 淘汰的异步结果写回；它不参与 transport retry。
+
+initial page、repair page 或 follow 的 terminal failure 进入当前 Session 的 `openError`。旧业务 epoch 或旧 stream 的失败不能覆盖新状态。
+
+#### Session live control
+
+`session.control()` 是 Host 范围的 snapshot stream，一个浏览器可观察所有当前 live Session 的瞬态状态，而不必为每个 transcript 打开 journal。
+
+每个 generation 先发完整 baseline，再发 queue、jobs 与 projection 增量帧。baseline 读取 attached Agent 和进程内 registry，不恢复冷 Agent。
+
+queue 与 jobs 使用完整 replacement 值并按 last-wins 应用。Agent attach、detach、Session disposal 与 owner disposal 都能用空值或新 baseline 清除陈旧镜像。
+
+原始 `approval/request` 与 `user-questions/request` 是可转发 waterfall。若某个 Agent-scoped Client listener claim，请求直接返回；若所有已投递 Client 都调用 `next()`，原 Cordis waterfall 继续到后续 Host listener。Session control 不保存或重放这些请求。
+
+projection baseline 与 tail page 的日志切点独立产生，Client 总是保留较高 seq 的值。订阅 live projection 不会为取得值而启动 Agent。
+
+Session added、removed、activity、running status 与无 turn 位置的 Agent error 不进入 stateful control stream；它们是可由列表 baseline 修复或无需重放的 `ctx.remote.$on` 通知。
+
+Session 列表的 `updatedAt` 取 `max(header.createdAt, sessionListMetadata.lastPromptAt)`。`lastPromptAt` 只由用户来源的 `user/message` 更新，可从冷 projection 恢复，不依赖浏览器是否正在跟随该 Session。
+
+### Workspace Controller
+
+`packages/api/workspace-controller` 提供 Host `ctx.workspaceController` 与生成的 `ctx.remote.workspace` namespace。
+
+它拥有 create、rename、delete、insertBefore、insertSessionBefore、archiveSession 与 `follow`。Workspace registry 仍是持久事实来源，Controller 负责 Remote 命令、投影和错误映射。
+
+`WorkspaceFeed` 同步观察 storage `domain/changed`，并为每个 follow generation 先发送完整 baseline，再发送 `upsert`、`remove`、`order` 与 `archived` 增量。
+
+完整 `order` frame 是 Workspace 排序的权威值。它避免 Client 根据 upsert 到达顺序猜测展示顺序，也能在重连 baseline 后收敛。
+
+`createWorkspaceStateStream()` 把 `workspace.follow` 装配为 `RemoteSnapshotStream`。Client Runtime 只负责启动和持有该 stream。
+
+`ClientWorkspaceModel` 位于 Workspace Controller 的 Client 面，拥有 baseline／increment 解析、已物化列表、归档集合、命令结果回显及 unary 与 stream 到达竞态的合并规则。
+
+成功的 unary 命令可以立即更新本地模型；后到的 stream commit 仍以 Host projection 与完整 order 校正状态。已删除 Workspace 的 id 被记录，延迟结果不能把它重新插回列表。
+
+```text
+ctx.remote.workspace.follow() -|[]> RemoteSnapshotStream
+                                      |-- replace(baseline)
+                                      |-- upsert/remove(view)
+                                      |-- replace(order)
+                                      `-- replace(archived ids)
+```
+
+Workspace Remote 方法、状态 feed 和 Client 数据模型均不经过 API Proxy，也不依赖 `host/workspace-*` 通知。
+
+### Remote Event
+
+Remote Event 复用 owner 包的 Cordis `Events` 声明。Host 原事件是唯一业务签名，Client `ctx.remote.$on(event, listener)` 从同一声明推导参数、waterfall 结果与 `next()`。
+
+`packages/api/remotes` 的 allowlist 是应用选择的唯一来源。每项显式标注 `emit` 或 `waterfall`，该 mode 同时决定 Host 监听方式、Client 合法键集和 wire frame 类型。
+
+系统不声明 `RemoteInvocationMap`，不要求 Client 再写一份 `@Remote`，也不以最后一个运行时参数是否为函数来猜测调用模式。
+
+Remote Event 下行帧是显式 discriminated union：
+
+```text
+ready     { type, clientId }
+emit      { type, event, args }
+waterfall { type, event, eventId, agentId, request }
+cancel    { type, eventId }
+```
+
+WebSocket JSON 与进程内 carrier 的入口都从 `unknown` 开始按 `type` 和精确字段验证；验证完成后的分发只接收 typed union。TypeScript 静态类型不替代 wire 校验。
+
+普通 `emit` 参数必须是无损 JSON。Client 在每个 Remote 实例私有的 Cordis key 上调用 `parallel()`，保留注册顺序、调用方 fiber 所有权和 listener 错误隔离。
+
+私有 key 防止 Host 事件与 Client 本地同名 Cordis 事件互相触发。Client Remote 不维护自己的 subscription registry 或手写 listener chain。
+
+可返回的 waterfall 当前只支持 Agent scope。事件签名必须是一个含直接 `agent` 字段的 request，加一个返回同类型结果的 `next()`，整体返回 Promise。
+
+Host 只投影 request 一级的 `agent` 与 `signal`：`agent` 变为 frame 的一级 `agentId`，`signal` 成为 delivery lifetime，其余字段必须整体为无损 JSON。
+
+Client 用 `agentId` 同步解析或物化 Agent Context，把当前 delivery signal 放回 request 的直接 `signal` 字段，再在目标 Context 的私有 key 上调用 Cordis `waterfall()`。Session-backed adapter 在首个成功 Session 列表 baseline 到达前允许 transport 先物化 scope；baseline 到达后由列表生命周期接管 scope 存活判断。
+
+系统不扫描任意深度对象，不传 path array 或 placeholder，不 deep clone／restore Context 和 AbortSignal，也不等待未来出现的 Agent Context。
+
+Client adapter 未注册、resolver 未返回 Context 或解析抛错时，本 Client 立即返回 `next`。它不订阅 registry、不做 resolve 后竞态复查，也不为一次 delivery 创建临时 Fiber。
+
+Gateway Host 为每个未完成 waterfall 保存 `eventId`、Host continuation 与已投递 Client generation。新 Client generation 会收到同一 pending event 的重放。
+
+每个 generation 的队列保证一次投递，因此 Client 不保存 `seen` 集合。`clientId + eventId` 绑定结果与当前 generation，旧连接的回包不能完成新连接上的 delivery。
+
+多 Client 同时接收 waterfall 时，第一个 result 或 rejection 完成 Host 调用，并向其余 Client 发送 `cancel`。只有所有已投递 Client 都返回 `next` 时，Gateway 才继续原 Cordis chain。
+
+Host caller signal 取消、Agent Context 释放、Client generation 结束和 losing-client cancellation 都会终止对应的等待。
+
+Client 通过现有 HTTP unary RPC `$events/result` 回送 `next`、result 或 rejection；下行事件仍复用 Remote WebSocket mux，不为应答建立 duplex WebSocket。
+
+Gateway 只验证 waterfall 返回值能无损表示为 JSON，不解释业务字段。Question 回答的 option 归属等语义由请求方或 UI 领域承担，transport 不重复校验。
+
+`UserQuestionService` 在请求期间观察到调用方 `AbortSignal` 已取消、且 provider 抛出普通错误时，将其归一为 `UserQuestionError` 的 `ASK_ABORTED`，并把原错误保留为 `cause`；provider 已给出的领域错误保持不变。
+
+`$events/result` 失败会令当前 Connection generation 失败。Host 随 generation 撤销该 Client 的 delivery，pending event 在下一 generation 重放，Client 不维护第二套结果重试队列。
+
+普通 `$on` 通知在断线后不重放。凡正确性依赖恢复的数据必须有 query、cursor 或 opening baseline，不能依赖 Remote Event 恰好送达。
+
+Client listener 晚于事件到达才注册时不补送；HMR 也没有专用补投语义。
+
+### API Proxy 的剩余边界
+
+Session Controller 与 Workspace Controller 直接提供生成 Remote namespace；API Remotes 与 API Gateway 直接提供 Host-to-Client 事件。
+
+Client Connection 只维护 Host generation、description 与通用 RPC，不解析领域 frame。
+
+Client Runtime 只接收 Controller adapter 产出的领域变更，不识别 `HostFrame`、`session/subscribed`、`session/event` mux frame 或 `host/workspace-*` frame。
+
+API Proxy 只承接自身拥有的独立业务 API，不是 Session、Workspace、Remote Event 或 Connection generation 的依赖。
+
+## 备选方案
+
+**建立任意 Session stream 时自动恢复 Agent。** 这会让查看历史、读取 title、重连标签页或观察后台状态产生执行副作用，也会让多个浏览器触发重复恢复；冷日志和投影已有 persistence 来源。
+
+**只允许 live Agent 使用 `session.follow`。** 这会迫使 transcript 首屏恢复 Agent，或重新引入 unary history 与 live subscription 之间的竞态；按 identity 先 follow 再冷读能同时覆盖历史和未来的显式激活。
+
+**把 Session transport 与 Session commands 拆成两个公开包。** 两者共同依赖 Session address、Agent 激活策略、subagent ownership、错误映射和 Client 挂载顺序；一个公开 Controller 保持统一所有权，内部 class 仍可独立演化。
+
+**把 queue、jobs、projection、Workspace 与日志都改成普通 `$on`。** 普通事件没有 reconnect baseline、cursor 或 gap repair，漏掉一次推送就会留下永久陈旧状态；只有无需恢复、可由独立查询修复，或以 waterfall 本身持有请求生命周期的通知适合 `$on`。
+
+**让每个领域 Controller 继承一个 page／follow／retry 基类。** Session journal 与 Workspace snapshot 的 opening、恢复和排序规则不同；Gateway 的三个组合式 stream 对象复用 transport 生命周期，同时让领域 adapter 只声明自己的 frame 语义。
+
+**给 Remote Event 新建一份 Client invocation 声明。** 第二张 map 或 Client `@Remote` 会复制 owner Cordis 事件签名并形成漂移点；从同一 `Events` 声明推导 `$on` listener 和结果类型可以构造性地保持一致。
+
+**把 Agent scope 做成任意深度对象投影。** 递归扫描 Context 与 AbortSignal 需要 path、placeholder、clone 和 restore 协议，并把偶然对象结构升级成 wire 约定；一级 `agent` 与 `signal` 足以覆盖当前 waterfall。
+
+**等待 Client Agent Context 或 adapter 后再分发。** registry waiter、竞态复查和临时 delivery Fiber 会为一个可同步解析或物化目标的 Client 增加额外生命周期；resolver 当下不能提供目标时立即 `next` 保持 Cordis waterfall 语义。
+
+**给 Remote Event 使用独立物理 WebSocket 或 duplex stream。** Gateway mux 已提供认证升级、复用、取消、错误映射和重连；下行 `$events` 加上 HTTP `$events/result` 足以表达 request／response，不需要第三条连接。
+
+**继续保留 API Proxy 的 Host mux。** 这会保留手写 union、schema、响应 envelope 和第二套 stream 生命周期，并使 Session 与 Workspace Controller 不能独立拥有自己的数据协议。
+
+**从聚合 `session/event` 更新 Session 列表时间。** 列表正确性会依赖浏览器正在消费哪些 Session，并把任意插件事件误判为用户活跃；持久 `lastPromptAt` 投影直接表达排序事实。

+# Agent Note: Client Session, Conversation, and UI ownership layers
+
+Status: implemented
+
+English | [中文](2026-08-20-client-session-conversation-ownership.zh.md)
+
+## Problem
+
+The Web Client once placed Session and Workspace objects, event windows, Conversation assembly, React hooks, the Slot registry, and the Store engine in one general Runtime. Protocol state, business projections, React bindings, and page presentation shared one dependency hub, so a change in any layer could spread across the entire frontend.
+
+Session snapshots could also accumulate data they did not own, including event arrays, Conversation Views, Chat Nodes, and pending interactions. Ordinary consumers then had to understand event replay and concrete views, while adding a Conversation target could require changes to Session, Runtime, and the renderer.
+
+Without an explicit interface between React and Session lifetimes, binding release, Hook source replacement, and Slot store cleanup became dedicated callback protocols. Approval and Question both affect sidebar state and composer takeover; independently maintained state could make those surfaces select different pending requests.
+
+The Client needs one-way dependencies between data owners, React adapters, generic rendering machinery, and concrete views while preserving application behavior.
+
+## Decision
+
+The Client uses the layering “Controller and domain object → UI adapter → renderer → Slot component.” Controllers and domain objects publish React-free observable sources; their `ui-*` packages declare standard props and register sources; `ui-renderer` creates selector hooks at Slot binding points; components read data and actions only from Slot props.
+
+```text
+[Remote / Controller / domain object]
+                  |
+                  | bare observable source
+                  v
+             [ui-* adapter]
+                  |
+                  | standard source registration
+                  v
+              [ui-renderer]
+                  |
+                  | selector hook binding
+                  v
+            [Slot component]
+```
+
+Client Session and Workspace objects belong to `api/session-controller/client` and `api/workspace-controller/client`, respectively. Target-neutral Conversation data structures and assembly belong to `client/ui-conversation`; Chat and Trajectory belong to `client/ui-chat` and `client/ui-trajectory`, respectively.
+
+The React adapters for Session and Workspace belong to `client/ui-session` and `client/ui-workspace`. The Store engine belongs to `client/store`; the Slot registry, scope materialization, and observable-to-hook binding belong to `client/ui-renderer`.
+
+The system has no aggregate `client/runtime` package and no replacement central facade. [Session history and event transport](2026-08-18-session-history-and-event-transport.md) defines Session history, Remote streams, pagination cursors, and reconnect continuity; this note starts from the Client objects and sources published by Controllers.
+
+## Layering principles
+
+### Controllers are React-free logic owners
+
+A Controller may be installed as a Cordis service, but it does not own React Contexts, React hooks, Slot props, or components. A Controller snapshot contains only facts that it owns, and its commands change only Host or domain-object state.
+
+The UI layer may read multiple Controllers for one navigation decision, but it does not write the combined result back into any Controller snapshot. A UI adapter does not duplicate a Controller command's business implementation.
+
+### UI adapters own React integration
+
+Each standard hook belongs to the `ui-*` package closest to its data semantics.
+
+| Hook | Owner | Source |
+| --- | --- | --- |
+| `useSessions` | `client/ui-session` | Session Controller global list |
+| `useSession` | `client/ui-session` | Current Session snapshot |
+| `useProjection` | `client/ui-session` | Current Session keyed projection |
+| `useSessionPendingInteraction` | `client/ui-session` | Aggregated pending domains |
+| `useWorkspaces` | `client/ui-workspace` | Workspace Controller list |
+| `useConversation` | `client/ui-conversation` | Conversation binding snapshot |
+| `useChat` | `client/ui-chat` | `chat` target source |
+| `useTrajectory` | `client/ui-trajectory` | `trajectory` target source |
+
+`ui-renderer` implements only generic binding. It does not import Session, Workspace, Conversation, Chat, or Trajectory business types or values.
+
+### Slot scopes and standard props are separate
+
+`ui-slots` declares root, session, and session-maybe scopes plus declaration-merge-extensible standard prop types. It does not decide which hooks each scope installs.
+
+`ui-renderer` implements generic scope adapters and source materialization. `ui-session` installs the Session scope and supplies its built-in sources; other domain packages register only their own sources and the Slot entries that consume them.
+
+Adding a target does not add a branch to the renderer or Session Controller. The data owner handles state identity, updates, errors, and release; the UI adapter owns the hook; the presentation owner owns target-specific projections and interaction state.
+
+## Package ownership
+
+| Package | Owns | Explicitly does not own |
+| --- | --- | --- |
+| `api/session-controller/client` | Session objects, list, selection, commands, projections, queue, event windows, and Agent Contexts | Conversation targets, React, Slots, Workspace |
+| `api/workspace-controller/client` | Workspace objects, ordering, archive state, commands, and snapshots | React, Session navigation policy, directory UI |
+| `client/ui-session` | Session scope, standard sources, `SessionProvider`, and pending-interaction aggregation | Session transport, Conversation assembly, Approval/Question results |
+| `client/ui-workspace` | Workspace hook, browser UI, and cross-Controller navigation policy | Workspace transport, copies of Session data |
+| `client/ui-conversation` | Conversation core, registries, bindings, shell, input, composer, queue, and View navigation | Session transport, Chat/Trajectory snapshots |
+| `client/ui-chat` | Chat target, Node definitions, renderers, selection, details, locale, and historical images | Session lifecycle, generic View navigation, Trajectory |
+| `client/ui-trajectory` | Trajectory target, event-record projection, and inspection view | Session snapshots, Chat snapshots |
+| `client/ui-approval` | Pending Approval, Remote listener, composer, and approval UI | Session control, generic composer election |
+| `client/ui-user-questions` | Pending Question, Remote listener, composer, and question UI | Session control, generic composer election |
+| `client/store` | React-free Store contract and implementation | Domain objects, React hooks, Slot lifetimes |
+| `client/ui-renderer` | SlotRegistry, scope binding, selector hooks, outlets, and React root | Session, Workspace, and Conversation business logic |
+
+## Overall data flow
+
+Session data reaches the UI through this path:
+
+```text
+[ctx.remote.session]
+          |
+          v
+[api/session-controller/client]
+  |-- SessionListState --------------------------> [ui-session] -> useSessions
+  |-- SessionSnapshot ----------------------------> [ui-session] -> useSession
+  |-- ProjectionValueSource ----------------------> [ui-session] -> useProjection
+  `-- per-Session SessionEventSource
+                    |
+                    v
+             [client/ui-conversation]
+                    |
+                    | assemble
+                    v
+             ConversationSnapshot ----------------> useConversation
+                    |
+          |---------+----------|
+          v                    v
+      [ui-chat]           [ui-trajectory]
+          |                    |
+       useChat            useTrajectory
+```
+
+Workspace data enters the Workspace Controller from `ctx.remote.workspace`, then `ui-workspace` exposes it as `useWorkspaces`. For cross-domain navigation, `ui-workspace` temporarily reads the Session Controller and issues a selection or command.
+
+Approval and Question arrive from the Host waterfall through `ctx.remote.$on` at their respective UI owners. Each owner publishes a Pending object; `ui-session.pendingInteractions` then supplies that same object to Session navigation state and Conversation composer selection.
+
+## Session Controller Client
+
+### Scope of SessionSnapshot
+
+`SessionSnapshot` represents control and lifecycle facts belonging to a Session. It may contain identity, running, removed, blank, subagent address, open phase, history phase, prompt error, agent error, and queue state.
+
+It does not contain:
+
+- a raw event array;
+- Conversation Views;
+- Chat Nodes;
+- Trajectory rows;
+- pending Approval or Question objects;
+- presentation state that requires callers to traverse events.
+
+Whether a field derives from an event, control frame, or local command does not automatically determine its owner; consumption semantics determine ownership. `composerPhase` depends on both Session lifecycle and Conversation target activity, so `ui-conversation` composes it instead of placing it in `SessionSnapshot`.
+
+### Three read faces
+
+The Session Controller exposes three distinct read faces:
+
+1. The global Session list and current-selection source, used by navigation and `useSessions`.
+2. A logical binding for each Session containing `sessionId`, a `SessionSnapshot` source, commands, and projection sources.
+3. A Conversation-facing `SessionEventSource` used only by the Conversation assembly core.
+
+Ordinary UI components do not read `SessionEventSource` directly. `ui-session` does not read private event windows, and the `ui-conversation` core receives neither React bindings nor Slot APIs.
+
+### SessionEventSource
+
+`SessionEventSource` exposes a materialized event window, not a transport.
+
+The window carries ordered `entries`, `hasMore`, a monotonic `revision`, and a `replace | prepend | append` change description. Append links an immutable segment in constant time; a consumer that needs the complete `entries` array materializes and caches it for that snapshot.
+
+Initial open, reconnect, gap repair, and updates whose continuity cannot be proven publish `replace`; history pagination publishes `prepend`; a continuous live event publishes `append`. The Conversation core selects incremental update or complete rebuild from the revision and change.
+
+`MutableSessionEventSource` is the Session Controller's internal write face. Consumers depend only on the read-only `SessionEventSource`.
+
+### Session binding lifecycle
+
+Each Session binding owns a Cordis Context and Fiber. The Session Controller creates and releases the binding.
+
+Objects that depend on a Session register cleanup through `binding.ctx.effect()`. Releasing a binding cleans up Conversation bindings, UI materializations, and scoped Slot stores without a dedicated `onBindingRelease` or `onRelease` callback protocol.
+
+This cleanup does not require the Session Controller to know the roster of upper-layer consumers.
+
+## UI Session
+
+### Service responsibilities
+
+`client/ui-session` is the sole Session adapter between the Session Controller and the React/Slot system. It provides `ctx.uiSession` and:
+
+- observes the Session list, current selection, and per-Session bindings;
+- installs the session and session-maybe scope adapters;
+- supplies `SessionProvider` rendering semantics;
+- supplies built-in Session snapshot, projection, and sessionId sources;
+- accepts Session-scoped source contributions from other domain packages;
+- aggregates pending interactions registered by business packages.
+
+It does not own Session transport, event folding, Conversation targets, or concrete business results.
+
+### Standard source registration
+
+A domain package calls `ctx.uiSession.provide()` to register a bare source. The descriptor statically declares its hook, keyed-hook, and prop rosters; `resolve(binding)` returns exactly those values for one Session binding. For example, `ui-conversation` registers each binding's snapshot as the `conversation` hook source.
+
+The renderer converts an ordinary source into `use<Name>`. Open key spaces such as projections use a keyed-hook resolver, while stable values use props.
+
+The runtime rejects undeclared, missing, or duplicate standard props. `ui-session` materializes its own built-ins through the same mechanism, so the renderer has no Session-specific name branches.
+
+### Scope binding
+
+session and session-maybe use the same adapter with different binding semantics:
+
+- a strict session scope refuses to render without a current binding;
+- session-maybe uses a stable absent binding to preserve hook call order;
+- changing the current Session rebuilds the strict Session subtree under the `sessionId` key;
+- root and session-maybe entries may remain mounted across Session changes.
+
+Each real materialized binding retains the Controller binding's Context. `ui-session` removes the cache entry and withdraws the current binding through `binding.ctx.effect()`.
+
+Changing the contribution roster rematerializes existing bindings and publishes a new source set. Source identity remains stable within one binding lifetime, as required by `useSyncExternalStore` caching.
+
+### SessionProvider
+
+`SessionProvider` is a standard seat derived by `PropsRenderSlots` from a session-scoped child declaration, not a React Context imported directly by business components.
+
+It accepts ordinary `ReactNode` children rather than a `(sessionId) => ReactNode` render function; callers wrap `renderSlot('details', {})` directly.
+
+Session identity comes from the scope binding and standard `sessionId` prop. The Provider handles only the absent branch and subtree isolation by Session identity; components do not obtain Session data through a Provider callback.
+
+### Pending interactions
+
+Business packages extend `SessionPendingInteractionMap` through declaration merging. Every pending object carries at least a stable `key`, domain `kind`, and `sessionId`; `ui-session` does not import concrete Approval or Question types.
+
+A business plugin calls `registerPendingInteraction(precedence)` in `apply()` to create a stable registration for its pending domain. The returned per-request publication function publishes one exact object together with its waterfall-delegation callback and returns an idempotent disposer for that object. Plugin teardown removes all published objects before invoking and awaiting their delegation callbacks, so active Host requests cannot remain suspended after their Client answerer unloads.
+
+Concurrent objects with the same key are rejected; replacement requests use a new key. One Session may hold multiple domains or requests at once.
+
+`ui-session` selects each Session's effective object using domain precedence. Higher precedence wins; at equal precedence, the later valid object in traversal order wins.
+
+The aggregate is published as `pendingInteractions: ObservableSnapshot<ReadonlyMap<SessionId, SessionPendingInteraction>>`; `useSessionPendingInteraction` is its React read face.
+
+Session navigation state and composer takeover read the same effective object. They do not maintain separate status maps or takeover rosters.
+
+## Workspace Controller and UI Workspace
+
+### Scope of WorkspaceSnapshot
+
+`WorkspaceSnapshot` contains only Host-authoritative data owned by the Workspace Controller, including Workspace rows, order, archive set, follow phase, and errors. A Workspace row's `sessionIds` is an association field, not a copy of Session objects in the Workspace snapshot.
+
+These combined facts do not enter `WorkspaceSnapshot`:
+
+- whether the Workspace and Session baselines are both ready;
+- the most recent Workspace derived from Session update times;
+- whether the current Session is cleared because it was archived;
+- which blank Session New Session should reuse;
+- which Session initial startup should select.
+
+### UI Workspace composition responsibilities
+
+`client/ui-workspace` registers the Workspace list source as the root standard source `workspaces`, from which the renderer provides `useWorkspaces`.
+
+Initial selection, blank-Session reuse, new-session navigation, concurrent-create coalescing, and navigation after archival are UI navigation policy. That policy may read both `ctx.workspaces` and `ctx.sessions` at decision time, but it issues only Controller commands and selection actions and does not publish a combined snapshot.
+
+Directory pickers, directory browsing, and `openPath` are separate directory capabilities and do not enter the Workspace Controller.
+
+## UI Conversation
+
+### Assembly core
+
+`client/ui-conversation` contains both the React-free Conversation assembly core and the React adapter for the same domain.
+
+The core owns `ConversationSnapshot`, the Definition registry, the View registry, the event assembler, the location index, per-Session bindings, target sources, and target activity.
+
+The core obtains `SessionEventSource` from a Session binding. Append and prepend changes with continuous revisions use incremental assembly; replace changes or revision gaps rebuild from the complete window.
+
+Definition or View roster changes rebuild only the Conversation binding; they do not rebuild a Session or reopen a Remote stream. The core does not import React and can test event folding, incremental updates, and registry lifetimes independently.
+
+`ConversationSnapshot` does not copy `SessionSnapshot` or expose raw events. It publishes only the target-neutral View roster, target activity, and target-source lookup.
+
+`useSession` and `useConversation` come from separate sources and are not guaranteed to publish atomically in one React commit. Components that read both compute purely from their current snapshots and do not treat notification order as business causality.
+
+### Definition and View registries
+
+`UiConversation.events` is the sole registry for event Definitions, and `UiConversation.views` is the sole registry for target snapshot builders.
+
+The registries reject duplicate keys, preserve registration order, and return idempotent disposers. Existing Conversation bindings rebuild from their current event windows when a roster changes; changes in one synchronous registration turn are coalesced into one microtask rebuild.
+
+A target package extends snapshot and location-data maps through declaration merging, then registers its Definitions, builder, and View. Registrations follow Cordis effect disposal.
+
+`ui-conversation` does not import concrete target packages.
+
+### Conversation React adapter
+
+The React adapter registers each Conversation binding snapshot as the Session standard source `conversation`, from which the renderer provides `useConversation`.
+
+The package also owns the shell, input, composer chain, queue UI, drafts, View navigation, and phase composition. The core reads no React Context, Slot props, or component state.
+
+View selection order is a valid persisted selection, registered `chat`, then no View. An invalid selection does not overwrite the persisted value, and the system does not fall back to the first registered View.
+
+Without `ui-chat`, the shell can still activate and mount but does not implicitly select Trajectory or another target.
+
+The shell phase is a pure composition of Session lifecycle and Conversation target activity. An active Session or any target reporting visible content produces active; a failed first prompt remains engaging.
+
+### Input and composer
+
+The composer chain belongs to `ui-conversation`; a concrete takeover belongs to its business package. `ConversationRoot` reads the current Session's effective object through `useSessionPendingInteraction` and supplies it to chain selectors as `ComposerChainProps.pendingInteraction`.
+
+A selector is a pure function of owner currency. Its non-null result reaches the selected component as `matched`. A stable composer entry and the default composer remain mounted together, while the chain selects one effective presentation.
+
+Draft and input state belong to Conversation UI and do not enter the Session snapshot. Queue commands use a Session-scoped service for addressing and do not write queue UI into the Conversation core.
+
+## Chat and Trajectory targets
+
+### Chat owner
+
+`client/ui-chat` registers target id `chat` and owns the Chat snapshot builder, Conversation Node definitions, keyed node renderers, selection, details, statistics, locale, Tool-inspection collaboration, and historical-image cache.
+
+It registers the `chat` target source through `ctx.uiSession.provide()`. `ChatNodeSeat` and internal Chat consumers use `useChat` instead of passing `useConversation(snapshot => snapshot.views.get('chat'))`.
+
+Only visible non-command Chat Nodes activate Chat. Ordinary command-only history keeps the Hero visible; the `/goal` `command-input` Node activates a fresh Conversation.
+
+The historical-image cache's Session key, pending promise, generation guard, blob URL, and disposer all belong to `ui-chat`; draft images remain part of Conversation input.
+
+### Trajectory owner
+
+`client/ui-trajectory` registers `trajectory` through the same target protocol. It owns event-record projection, timelines, virtual rows, selection, and the inspection view, and exposes `useTrajectory` through a standard source.
+
+Session lifecycle reads `useSession`, while Trajectory data reads `useTrajectory`. Trajectory does not obtain its own data through a Session or Chat snapshot.
+
+Other targets use the same registration flow without modifying the renderer, Session Controller, or ui-session.
+
+## Approval and Question
+
+### Stable registration
+
+Approval and Question plugin installation separates stable registrations from per-request handling. `apply()` registers locale data, calls `registerPendingInteraction()` once for its pending domain, and registers one stable entry in `conversation.composer`.
+
+The stable Approval entry also declares its detail child Slot. Concurrent requests and Session count do not add composer entries or redeclare Slots, and every registration follows plugin-fiber disposal.
+
+### One waterfall request
+
+A Remote Event listener resolves the Session from its own Agent Context. Without a Session scope it calls `next()` to continue the waterfall; with a Session scope it creates a `PendingApproval` or `PendingQuestion`.
+
+The listener publishes the object through the registered domain publication function, waits for user completion, cancellation, or request-signal abortion, and removes the exact object in `finally`.
+
+One request does not register a Slot, create another lifecycle effect, or mutate the Session snapshot.
+
+Approval exposes allow and reject; Question exposes answer and cancel. User cancellation of a Question returns `ASK_CANCELLED`; interruption of a pending request by `AbortSignal` returns `UserQuestionError(ASK_ABORTED)` rather than leaking the carrier's `AbortError` or an ordinary `Error`.
+
+The Gateway requires only that Remote Event arguments and results are valid JSON transport values. It does not duplicate domain validation of Question options.
+
+### One pending projection
+
+The Sidebar and composer consume the same `pendingInteractions` snapshot. Navigation displays approval, plan-review, or question state from the effective object's `kind`; each composer entry selects its own panel by object identity.
+
+The same request identity drives both UI surfaces. A request that replaces another request of the same type uses a new key, so selectors and subscribers observe the identity change.
+
+`ui-session` implements only cross-domain precedence and does not interpret Approval or Question fields.
+
+## UI Renderer and Store
+
+### UI Renderer
+
+`client/ui-renderer` owns the `SlotRegistry` service and React renderer. It is responsible for:
+
+- `ctx.slots.register()`, `inject()`, `renderSlot()`, and declaration lifetimes;
+- root, session, and session-maybe scope adapters;
+- binding standard observable sources to selector hooks;
+- Slot outlets, error isolation, root mount, and hydration;
+- managing Slot store instance lifetimes by scope key.
+
+The renderer may know generic scope names and binding protocols but does not read domain services. Rendering Session scope without an installed adapter is an assembly error that fails immediately.
+
+### Store
+
+`client/store` is a plain React-free library owning `ObservableSnapshot`, `SnapshotStore`, `defineStore`, `createSnapshotStore`, and `shallowEqual`.
+
+`ui-slots` references the Store contract; `ui-renderer` manages Store instances and supplies `useStore`.
+
+Stores hold viewing and interaction state such as drafts, View selection, Chat selection, inspection requests, and panel size. Session, Workspace, Conversation, Remote streams, and connection generations do not enter Stores.
+
+### Registration and release order
+
+When one plugin provides both a source and a Slot entry, it registers the source first and the entry second. Reverse Cordis disposal then removes the entry before the source, so a mounted entry never briefly loses a required hook.
+
+Releasing a Session binding cleans up UI materialization and scoped Stores through `binding.ctx.effect()`. Releasing a plugin fiber cleans up sources, listeners, and Slot entries through registration disposers.
+
+Every disposer is idempotent and depends on no implicit callback outside the Cordis lifecycle.
+
+## Composition and dependency direction
+
+The application bundle explicitly installs the required Controller, adapter, target, and renderer plugins. Each owner's `apply()` installs only its own service, listener, and contributions.
+
+Runtime consumption flows as `session-controller → ui-session → ui-conversation → target UI`, `workspace-controller → ui-workspace`, and `store → ui-slots → ui-renderer`; Approval and Question depend only on the pending-registration point exposed by `ui-session`.
+
+Arrows in this description represent runtime consumption and do not include type-only declaration-merge edges. Controllers do not depend back on UI adapters, the renderer does not depend back on domain packages, and the Conversation core does not depend on a concrete target.
+
+UI components do not receive `ctx`. Cross-package collaboration uses Cordis services, standard sources, or Slot registrations without introducing an aggregate facade.
+
+## Developer guidance
+
+### Choose the data owner first
+
+Before adding state, choose its sole owner from its consumption semantics: Host communication, commands, and entity lifecycle belong to an API Controller; data assembled from Session events but independent of a target belongs to the Conversation core; projections serving only one View belong to that target package; drafts, selections, and panel state belong to the UI package that owns the interaction.
+
+The same fact must not be retained simultaneously in a Controller snapshot, Conversation snapshot, and Store. A cross-domain decision reads multiple sources and immediately issues a command; it does not create a joined snapshot or cache another domain's object.
+
+These are signs of incorrect ownership: a Controller imports React; the renderer branches on business types; a component traverses Session events; a Store holds Session or Workspace entities; changing one target requires changing the Session Controller.
+
+### Add Session-scoped data
+
+1. Provide a React-free observable source in the domain owner.
+2. Declaration-merge the standard prop type in the owning UI adapter.
+3. Declare a fixed roster through `ctx.uiSession.provide()` and resolve its source from a Session binding.
+4. Let the Slot component receive the generated hook through `PropsRuntime`; do not pass `ctx` to a component.
+5. Attach each binding resource's cleanup to `binding.ctx.effect()` and leave registration cleanup to the plugin fiber.
+6. Test missing values, duplicate names, roster replacement, Session changes, and binding disposal.
+
+Only open key spaces use keyed hooks. Finite stable sources use ordinary hooks, and immutable identifiers use props. Do not hard-code business names in the renderer to save one registration.
+
+### Add a Conversation target
+
+1. Extend the Conversation snapshot or location-data map in the target package.
+2. Register the required event Definitions with `UiConversation.events`.
+3. Register the snapshot builder, target id, View, and activity rule with `UiConversation.views`.
+4. Expose the target's standard selector hook through `ctx.uiSession.provide()`.
+5. Register the renderer, locale, and target-specific Slot entries in the same package.
+6. Verify that unloading the target rebuilds only the Conversation binding without changing the Session, other targets, or Remote stream.
+
+A target must not use another target's snapshot as its data source. Optional collaboration uses a narrow port or Slot; when a target is absent, the shell remains bootable and does not guess a fallback.
+
+### Add a pending-interaction domain
+
+1. Define the Pending object and its completion, cancellation, and interruption semantics in the business package.
+2. Add the object to `SessionPendingInteractionMap` through declaration merging.
+3. Call `registerPendingInteraction()` once in `apply()` and register one stable composer entry.
+4. Resolve the Session from the Agent Context in the Remote waterfall listener; call `next()` when the listener cannot handle the request.
+5. When it can handle the request, create the Pending object, publish it through the publication function, await its result, and remove it in `finally`.
+6. Test concurrent keys, precedence, user cancellation, transport abort, plugin disposal, and delegation without a Session.
+
+A request does not register Slots, declare child Slots, mutate the Session snapshot, or create a separate state index. Sidebar and composer both read one effective object from `useSessionPendingInteraction`.
+
+### Review checks
+
+- Every new source, registry contribution, listener, and cache has an explicit Cordis-fiber or Session-binding owner.
+- Every public hook traces to one React-free source; no selector is forwarded through layers only to pass arguments.
+- Every component obtains data and actions from standard props or the owning Slot's inject face.
+- Every target has defined behavior when absent, dynamically registered, and unloaded.
+- Every cross-layer import advances in the one-way Controller, adapter, renderer, component direction.
+- Each error is classified by the earliest owner that can explain its semantics; carrier errors do not leak directly as business errors.
+
+## Verification
+
+Tests owned by each layer pin Controller bindings and event sources, UI scopes and pending precedence, incremental Conversation assembly and View fallback, target projections, waterfall results, and renderer scope/Store lifetimes. Application-composition tests cover both the complete roster and startup without a concrete target; component tests do not replace object-layer, replay, and lifecycle tests.
+
+## Alternatives considered
+
+- **Keep a Runtime facade.** One entry point would retain the dependency hub and let new code bypass domain owners, so the system provides neither the facade nor a compatibility export.
+- **Put all Client state in API Controllers.** Protocol objects would then own React, Views, and presentation policy, so Controllers retain only React-free domain state.
+- **Let Controllers provide React hooks directly.** Non-React consumers could not reuse the same objects, and transport and renderer lifetimes would become interdependent.
+- **Put Conversation in SessionSnapshot.** This would expand the Session API and force ordinary Session consumers to understand event folding and target rosters.
+- **Let Chat and Trajectory replay Session events independently.** Ordering, locations, and registry rebuild would be duplicated, so the shared assembly core stays in `ui-conversation`.
+- **Extract the Conversation core into another non-UI package.** The core and adapter currently evolve together and have no other non-UI package consumer; directory separation within one package keeps the core React-free.
+- **Combine Workspace and Session into one snapshot.** This would create another cross-domain owner, so cross-domain logic remains an immediate decision in `ui-workspace`.
+- **Build every standard hook into the renderer.** Generic infrastructure would need to know every domain, so standard-source registration keeps the renderer independent from business types.
+- **Dynamically register a composer entry for every pending request.** This would redeclare child Slots and make concurrent requests compete through registration order, so stable entries are separate from request publication.
+- **Write pending interactions into a Session projection.** An unanswered waterfall is not a committed durable Session fact; Remote Event replay restores it after refresh, so it remains in a business UI source.
+- **Add a dedicated release callback to bindings.** This would duplicate the Cordis lifecycle; `binding.ctx.effect()` already attaches consumer cleanup to the same owner.
+- **Pass the Session id from SessionProvider through a render function.** This would create another data-injection path; ordinary children and the standard `sessionId` prop retain one entry for scoped data.
+- **Keep Store in the renderer.** The Store contract does not depend on React and is reused by objects and test infrastructure, so `client/store` keeps the engine separate from rendering lifetimes.
+
+## Consequences
+
+Session, Workspace, Conversation, and each concrete target own one authoritative state. Non-React consumers can reuse Controllers and the assembly core directly. A new Conversation target registers its Definition, builder, View, standard source, and Slot entries; a new pending-interaction domain declares its type, registers its domain, and provides one stable composer entry.
+
+The renderer and Session Controller gain no branch for a new business domain, while Session bindings and plugin fibers provide two explicit, composable release paths. The UI can observe independent Session and Conversation source publications, and consumers cannot depend on their notification order.
+
+Composition packages must explicitly load the required adapter and target plugins. The shell remains operational without a concrete target but neither creates nor guesses that target's View. More packages and explicit registrations add assembly work, while dependency direction, test scope, and failure ownership become locally identifiable.

+# Agent Note: Client Session、Conversation 与 UI 所有权分层
+
+Status: implemented
+
+[English](2026-08-20-client-session-conversation-ownership.md) | 中文
+
+## 问题
+
+Web Client 曾由一个通用 Runtime 同时承载 Session 与 Workspace 对象、事件窗口、Conversation 组装、React hooks、Slot 注册表和 Store 引擎。协议状态、业务投影、React 绑定和页面呈现共享同一个依赖汇点，任何一层的变化都可能扩大到完整前端。
+
+Session 快照也容易混入事件数组、Conversation View、Chat Node 和待处理交互等并非 Session 自身拥有的数据。普通消费者由此需要理解事件重放与具体视图，新增一个 Conversation target 也可能要求修改 Session、Runtime 和 renderer。
+
+React 生命周期与 Session 生命周期之间缺少明确接口时，binding 释放、Hook source 替换和 Slot store 清理会演变为互相回调的专用协议。Approval 与 Question 同时影响侧边栏状态和 composer takeover；若两处各自维护状态，它们还可能选择不同的待处理请求。
+
+需要把数据 owner、React adapter、通用渲染机制和具体视图拆成单向依赖，同时保持既有应用行为。
+
+## 决定
+
+Client 采用“Controller 与领域对象 → UI adapter → renderer → Slot component”的分层。Controller 和领域对象发布不依赖 React 的 observable source；所属 `ui-*` package 声明标准 props 并注册 source；`ui-renderer` 在 Slot binding 点生成 selector hook；组件只从 Slot props 读取数据与操作。
+
+```text
+[Remote / Controller / domain object]
+                  |
+                  | bare observable source
+                  v
+             [ui-* adapter]
+                  |
+                  | standard source registration
+                  v
+              [ui-renderer]
+                  |
+                  | selector hook binding
+                  v
+            [Slot component]
+```
+
+Session 与 Workspace 的 Client 对象分别归 `api/session-controller/client` 和 `api/workspace-controller/client`。Conversation 的 target-neutral 数据结构和组装归 `client/ui-conversation`，Chat 与 Trajectory 分别归 `client/ui-chat` 和 `client/ui-trajectory`。
+
+Session 与 Workspace 的 React 适配分别归 `client/ui-session` 和 `client/ui-workspace`。Store engine 归 `client/store`，Slot registry、scope materialization 和 observable-to-hook 绑定归 `client/ui-renderer`。
+
+系统不提供聚合式 `client/runtime` package，也不设置替代它的总控 facade。Session history、Remote stream、分页 cursor 和重连连续性由 [Session 历史与事件传输](2026-08-18-session-history-and-event-transport.zh.md) 定义；本 Note 从 Controller 发布的 Client 对象与 source 开始。
+
+## 分层原则
+
+### Controller 是无 React 的逻辑 owner
+
+Controller 可以作为 Cordis service 安装，但不拥有 React Context、React hook、Slot props 或组件。Controller snapshot 只包含自身拥有的事实，命令只改变 Host 或领域对象状态。
+
+UI 层可以同时读取多个 Controller 做一次导航决定，但不得把组合结果写回任一 Controller snapshot。UI adapter 也不复制 Controller 命令的业务实现。
+
+### UI adapter 拥有 React 接入
+
+每个标准 hook 归最接近其数据语义的 `ui-*` package。
+
+| Hook | Owner | Source |
+| --- | --- | --- |
+| `useSessions` | `client/ui-session` | Session Controller 全局列表 |
+| `useSession` | `client/ui-session` | 当前 Session snapshot |
+| `useProjection` | `client/ui-session` | 当前 Session keyed projection |
+| `useSessionPendingInteraction` | `client/ui-session` | pending domain 聚合结果 |
+| `useWorkspaces` | `client/ui-workspace` | Workspace Controller 列表 |
+| `useConversation` | `client/ui-conversation` | Conversation binding snapshot |
+| `useChat` | `client/ui-chat` | `chat` target source |
+| `useTrajectory` | `client/ui-trajectory` | `trajectory` target source |
+
+`ui-renderer` 只实现通用绑定，不 import Session、Workspace、Conversation、Chat 或 Trajectory 的业务类型和值。
+
+### Slot scope 与标准 props 分离
+
+`ui-slots` 声明 root、session 和 session-maybe scope，以及可通过 declaration merge 扩展的标准 props 类型；它不决定每个 scope 安装哪些 hook。
+
+`ui-renderer` 实现通用 scope adapter 与 source materialization。`ui-session` 安装 Session scope 并提供内建 source，其他领域 package 只注册自己的 source 和消费它的 Slot entry。
+
+新增 target 不要求 renderer 或 Session Controller 增加分支。数据 owner 负责状态身份、更新、错误和释放；UI adapter 负责 hook；显示 owner 负责 target-specific projection 与交互状态。
+
+## Package 所有权
+
+| Package | 拥有内容 | 明确不拥有 |
+| --- | --- | --- |
+| `api/session-controller/client` | Session 对象、列表、选择、命令、projection、queue、事件窗口和 Agent Context | Conversation target、React、Slot、Workspace |
+| `api/workspace-controller/client` | Workspace 对象、顺序、归档、命令和 snapshot | React、Session 导航策略、目录 UI |
+| `client/ui-session` | Session scope、标准 source、`SessionProvider`、pending interaction 聚合 | Session transport、Conversation 组装、Approval/Question 结果 |
+| `client/ui-workspace` | Workspace hook、浏览器 UI 和跨 Controller 导航策略 | Workspace transport、Session 数据副本 |
+| `client/ui-conversation` | Conversation core、registry、binding、shell、input、composer、queue 和 View 导航 | Session transport、Chat/Trajectory snapshot |
+| `client/ui-chat` | Chat target、Node definitions、renderer、selection、details、locale 和历史图片 | Session 生命周期、通用 View 导航、Trajectory |
+| `client/ui-trajectory` | Trajectory target、事件记录投影和检查视图 | Session snapshot、Chat snapshot |
+| `client/ui-approval` | Pending Approval、Remote listener、composer 和审批 UI | Session control、通用 composer election |
+| `client/ui-user-questions` | Pending Question、Remote listener、composer 和问题 UI | Session control、通用 composer election |
+| `client/store` | React-free store contract 与实现 | 领域对象、React hook、Slot 生命周期 |
+| `client/ui-renderer` | SlotRegistry、scope binding、selector hook、outlet 和 React root | Session、Workspace 与 Conversation 业务逻辑 |
+
+## 总体数据流
+
+Session 数据按以下路径进入 UI：
+
+```text
+[ctx.remote.session]
+          |
+          v
+[api/session-controller/client]
+  |-- SessionListState --------------------------> [ui-session] -> useSessions
+  |-- SessionSnapshot ----------------------------> [ui-session] -> useSession
+  |-- ProjectionValueSource ----------------------> [ui-session] -> useProjection
+  `-- per-Session SessionEventSource
+                    |
+                    v
+             [client/ui-conversation]
+                    |
+                    | assemble
+                    v
+             ConversationSnapshot ----------------> useConversation
+                    |
+          |---------+----------|
+          v                    v
+      [ui-chat]           [ui-trajectory]
+          |                    |
+       useChat            useTrajectory
+```
+
+Workspace 数据从 `ctx.remote.workspace` 进入 Workspace Controller，再由 `ui-workspace` 暴露为 `useWorkspaces`；需要跨域导航时，`ui-workspace` 临时读取 Session Controller 并发出选择或命令。
+
+Approval 与 Question 从 Host waterfall 经 `ctx.remote.$on` 到达各自 UI owner。Owner 发布 Pending 对象，`ui-session.pendingInteractions` 再把同一对象送往 Session 导航状态和 Conversation composer selection。
+
+## Session Controller Client
+
+### SessionSnapshot 的范围
+
+`SessionSnapshot` 表示 Session 自身的控制与生命周期事实。它可以包含 identity、running、removed、blank、subagent address、open phase、history phase、prompt error、agent error 和 queue 状态。
+
+它不包含以下数据：
+
+- raw event array；
+- Conversation View；
+- Chat Node；
+- Trajectory row；
+- Approval 或 Question 的待处理对象；
+- 要求调用者遍历 event 才能解释的呈现状态。
+
+字段由 event、control frame 或本地命令推导，并不自动决定其 owner；消费语义决定 owner。`composerPhase` 同时依赖 Session lifecycle 与 Conversation target activity，因此由 `ui-conversation` 合成，不进入 `SessionSnapshot`。
+
+### 三个读取面
+
+Session Controller 对外提供三个互不替代的读取面：
+
+1. 全局 Session list 与 current selection source，供导航和 `useSessions` 使用。
+2. 每个 Session 的逻辑 binding，包含 `sessionId`、`SessionSnapshot` source、commands 与 projection sources。
+3. Conversation-facing `SessionEventSource`，只供 Conversation assemble core 使用。
+
+普通 UI component 不直接读取 `SessionEventSource`。`ui-session` 不读取私有 event window，`ui-conversation` core 也不接收 React binding 或 Slot API。
+
+### SessionEventSource
+
+`SessionEventSource` 暴露已经物化的事件窗口，而不是 transport。
+
+窗口携带有序 `entries`、`hasMore`、单调 `revision`，以及 `replace | prepend | append` 变更描述。Append 以常数时间连接不可变片段；需要完整 `entries` 数组的消费者才为该 snapshot 物化并缓存数组。
+
+首次打开、重连、gap repair 和无法证明连续性的更新发布 `replace`；历史分页发布 `prepend`；连续 live event 发布 `append`。Conversation core 依据 revision 与 change 选择增量更新或完整 rebuild。
+
+`MutableSessionEventSource` 是 Session Controller 内部写端，消费者只依赖只读的 `SessionEventSource`。
+
+### Session binding 生命周期
+
+每个 Session binding 持有自己的 Cordis Context 与 Fiber。Session Controller 创建 binding，也负责释放它。
+
+依赖 Session 的对象把清理注册到 `binding.ctx.effect()`。Binding 释放会触发 Conversation binding、UI materialization 和 scoped Slot store 的清理，不存在额外的 `onBindingRelease` 或 `onRelease` 回调协议。
+
+这种清理方式不要求 Session Controller 了解上层消费者名册。
+
+## UI Session
+
+### 服务职责
+
+`client/ui-session` 是 Session Controller 与 React/Slot 系统之间唯一的 Session adapter。它提供 `ctx.uiSession`，并负责：
+
+- 观察 Session list、current selection 和 per-Session binding；
+- 安装 session 与 session-maybe scope adapter；
+- 提供 `SessionProvider` 的呈现语义；
+- 内建 session snapshot、projection 和 sessionId source；
+- 接收其他领域 package 的 Session-scoped source contribution；
+- 聚合业务 package 注册的 pending interaction。
+
+它不拥有 Session transport、event folding、Conversation target 或具体业务结果。
+
+### 标准 source 注册
+
+领域 package 调用 `ctx.uiSession.provide()` 注册 bare source。Descriptor 静态声明 hooks、keyedHooks 和 props 名册，`resolve(binding)` 为一个 Session binding 返回完全对应的值；例如 `ui-conversation` 把每个 binding 的 snapshot 注册为 `conversation` hook source。
+
+普通 source 被 renderer 转换成 `use<Name>`，Projection 等开放 key 空间通过 keyed hook resolver 暴露，稳定值通过 props 暴露。
+
+运行时拒绝未声明、缺失或重复的标准 prop。`ui-session` 自身也走相同 materialization，renderer 不为 Session 名字写特殊分支。
+
+### Scope binding
+
+session 与 session-maybe 使用同一个 adapter，但绑定语义不同：
+
+- strict session scope 在没有 current binding 时拒绝渲染；
+- session-maybe 使用稳定 absent binding，保持 hook 调用顺序；
+- current Session 切换以 `sessionId` 为 key 重建严格 Session subtree；
+- root 与 session-maybe entry 可以跨 Session 切换常驻。
+
+每个真实 materialized binding 保留 Controller binding 的 Context。`ui-session` 通过 `binding.ctx.effect()` 删除缓存项并撤销 current binding。
+
+Contribution roster 变化会重建已 materialize 的 binding 并发布新的 source 集合。同一 binding 生命周期内，source identity 保持稳定，以满足 `useSyncExternalStore` 的缓存要求。
+
+### SessionProvider
+
+`SessionProvider` 是 `PropsRenderSlots` 根据 session-scoped child 声明派生的标准席，不是业务 component 直接 import 的 React Context。
+
+它接收普通 `ReactNode` children，不接收 `(sessionId) => ReactNode` render function；调用方直接用它包裹 `renderSlot('details', {})`。
+
+Session identity 通过 scope binding 和标准 `sessionId` prop 提供。Provider 只负责 absent branch 与按 Session identity 隔离 subtree，组件不得借助 Provider 回调取得 Session 数据。
+
+### Pending interaction
+
+`SessionPendingInteractionMap` 由业务 package declaration merge 扩展。每个 pending object 至少携带稳定 `key`、领域 `kind` 和 `sessionId`；`ui-session` 不 import Approval 或 Question 的具体类型。
+
+业务 plugin 在 `apply()` 中调用 `registerPendingInteraction(precedence)`，为自己的 pending domain 建立稳定注册。该调用返回逐请求 publication function；publication function 同时发布精确对象及其 waterfall 委托回调，并返回移除该对象的幂等 disposer。Plugin teardown 会先移除所有已发布对象，再调用并等待其委托回调，避免 Client 回答者卸载后 Host 请求继续悬挂。
+
+相同 key 的并发对象被拒绝，替换请求必须使用新 key。同一 Session 可以同时存在多个领域或多个请求。
+
+`ui-session` 使用各 domain 的 precedence 选出每个 Session 当前生效的对象。较高 precedence 胜出，相同 precedence 下后遍历到的有效对象胜出。
+
+聚合结果发布为 `pendingInteractions: ObservableSnapshot<ReadonlyMap<SessionId, SessionPendingInteraction>>`，`useSessionPendingInteraction` 是其 React 读取面。
+
+Session 导航状态和 composer takeover 必须读取同一个 effective object，不得分别维护 status map 或 takeover roster。
+
+## Workspace Controller 与 UI Workspace
+
+### WorkspaceSnapshot 的范围
+
+`WorkspaceSnapshot` 只包含 Workspace Controller 拥有的 Host-authoritative 数据，包括 Workspace rows、顺序、archive set、follow phase 和错误。Workspace row 的 `sessionIds` 是关联字段，不等于把 Session 对象复制进 Workspace snapshot。
+
+以下组合事实不进入 `WorkspaceSnapshot`：
+
+- Workspace 与 Session 两条 baseline 是否同时 ready；
+- 根据 Session 更新时间推导的最近 Workspace；
+- 当前 Session 是否因归档而清除；
+- New Session 应复用哪个 blank Session；
+- 首次启动应选择哪个 Session。
+
+### UI Workspace 的组合职责
+
+`client/ui-workspace` 把 Workspace list source 注册为 root 标准 source `workspaces`，renderer 由此提供 `useWorkspaces`。
+
+初始选择、blank Session 复用、新建导航、并发创建合并和归档后导航属于 UI navigation policy。该 policy 可以在决定时同时读取 `ctx.workspaces` 与 `ctx.sessions`，但只调用 Controller command 和 selection action，不发布联合 snapshot。
+
+目录 picker、目录浏览和 `openPath` 属于独立目录能力，不进入 Workspace Controller。
+
+## UI Conversation
+
+### Assemble core
+
+`client/ui-conversation` 同时包含不依赖 React 的 Conversation assemble core 和同领域的 React adapter。
+
+Core 拥有 `ConversationSnapshot`、Definition registry、View registry、event assembler、location index、每 Session binding、target source 和 target activity。
+
+Core 从 Session binding 取得 `SessionEventSource`。连续 revision 的 append 与 prepend 使用增量组装；replace 或 revision 断档从完整窗口 rebuild。
+
+Definition 或 View roster 变化只重建 Conversation binding，不重建 Session 或重开 Remote stream。Core 不 import React，可独立测试事件折叠、增量更新和 registry lifecycle。
+
+`ConversationSnapshot` 不复制 `SessionSnapshot`，也不暴露 raw events；它只发布 target-neutral 的 View 名册、target activity 和 target source lookup。
+
+`useSession` 与 `useConversation` 来自两个 source，不承诺在同一个 React commit 原子发布。同时读取两者的组件按当前 snapshot 纯计算，不把通知顺序解释为业务因果。
+
+### Definition 与 View registry
+
+`UiConversation.events` 是 event Definition 的唯一 registry，`UiConversation.views` 是 target snapshot builder 的唯一 registry。
+
+Registry 拒绝重复 key，保持注册顺序并返回幂等 disposer。Roster 变化时，现有 Conversation binding 使用当前 event window 重建；同一同步注册轮次中的变化会合并为一次 microtask 重建。
+
+Target package 通过 declaration merge 扩展 snapshot 与 location data map，再向 registry 注册自己的 Definition、builder 和 View。注册随 Cordis effect 释放。
+
+`ui-conversation` 不 import 具体 target package。
+
+### Conversation React adapter
+
+React adapter 把每个 Conversation binding 的 snapshot 注册为 Session 标准 source `conversation`，renderer 由此提供 `useConversation`。
+
+同包还拥有 shell、input、composer chain、queue UI、draft、View navigation 和 phase 合成；Core 不读取 React Context、Slot props 或 component state。
+
+View 选择顺序固定为：有效的持久化 selection、已注册的 `chat`、无 View。无效 selection 不覆盖持久化值，系统不 fallback 到第一个已注册 View。
+
+没有 `ui-chat` 时 shell 仍能激活和 mount，但不会隐式选择 Trajectory 或其他 target。
+
+Shell phase 由 Session lifecycle 与 Conversation target activity 纯合成。Session 已 active 或任一 target 报告可见内容时显示 active；首条 prompt 失败仍保持 engaging。
+
+### Input 与 composer
+
+Composer chain 属于 `ui-conversation`，具体 takeover 属于业务 package。`ConversationRoot` 从 `useSessionPendingInteraction` 读取当前 Session 的 effective object，并作为 `ComposerChainProps.pendingInteraction` 交给 chain selector。
+
+Selector 是 owner currency 的纯函数，非 null 结果作为 `matched` 传给获选 component。Stable composer entry 与默认 composer 可以同时常驻，chain 只选择一个有效呈现。
+
+Draft 与输入状态属于 Conversation UI，不进入 Session snapshot。Queue command 通过 Session-scoped service 寻址，不把 queue UI 写入 Conversation core。
+
+## Chat 与 Trajectory target
+
+### Chat owner
+
+`client/ui-chat` 注册 target id `chat`，并拥有 Chat snapshot builder、Conversation Node definitions、keyed node renderers、selection、details、stats、locale、tool inspection 协作和历史图片 cache。
+
+它通过 `ctx.uiSession.provide()` 注册 `chat` target source。`ChatNodeSeat` 和 Chat 内部消费者使用 `useChat`，不再传递 `useConversation(snapshot => snapshot.views.get('chat'))`。
+
+Chat activity 只由可见且非 command 的 Chat Node 激活。普通 command-only history 保持 Hero，`/goal` 的 `command-input` Node 激活 fresh Conversation。
+
+历史图片 cache 的 Session key、pending promise、generation guard、blob URL 和 disposer 同属 `ui-chat`；Draft 图片仍属于 Conversation input。
+
+### Trajectory owner
+
+`client/ui-trajectory` 通过相同 target 协议注册 `trajectory`。它拥有事件记录、时间线、虚拟行、selection 和 inspection view，并通过标准 source 提供 `useTrajectory`。
+
+Session 生命周期读取 `useSession`，Trajectory 数据读取 `useTrajectory`。Trajectory 不通过 Session snapshot 或 Chat snapshot 取得自己的数据。
+
+其他 target 使用同一注册流程，不修改 renderer、Session Controller 或 ui-session。
+
+## Approval 与 Question
+
+### 稳定注册
+
+Approval 和 Question 的 plugin 安装分为稳定注册与单次请求处理。`apply()` 注册 locale、调用 `registerPendingInteraction()` 注册本领域 pending domain，并向 `conversation.composer` 注册唯一稳定 entry。
+
+Approval 的 detail child Slot 也由稳定 entry 声明。并发请求和 Session 数量不会增加 composer entry 或重复声明 Slot，所有注册随 plugin fiber 释放。
+
+### 单次 waterfall 请求
+
+Remote Event listener 从自身 Agent Context 解析 Session。没有 Session scope 时调用 `next()` 继续 waterfall；存在 Session scope 时创建 `PendingApproval` 或 `PendingQuestion`。
+
+Listener 通过已注册 domain 的 publication function 发布对象，等待用户完成、取消或请求 signal 中止，并在 `finally` 中精确移除对象。
+
+单次请求不注册 Slot，不创建第二套 lifecycle effect，也不修改 Session snapshot。

+
+同一请求 identity 同时驱动两处 UI。新请求替换同类型旧请求时使用新 key，因此 selector 与订阅者都观察到身份变化。
+
+`ui-session` 只实现跨领域 precedence，不解释 Approval 或 Question 的字段。
+
+## UI Renderer 与 Store
+
+### UI Renderer
+
+`client/ui-renderer` 拥有 `SlotRegistry` service 和 React renderer。它负责：
+
+- `ctx.slots.register()`、`inject()`、`renderSlot()` 与声明生命周期；
+- root、session 和 session-maybe scope adapter；
+- 标准 observable source 到 selector hook 的绑定；
+- Slot outlet、错误隔离、root mount 与 hydration；
+- 按 scope key 管理 Slot store instance 生命周期。
+
+Renderer 可以认识通用 scope 名称和 binding 协议，但不读取领域 service。渲染 Session scope 而没有安装 adapter 是装配错误，并立即失败。
+
+### Store
+
+`client/store` 是 React-free 普通库，拥有 `ObservableSnapshot`、`SnapshotStore`、`defineStore`、`createSnapshotStore` 和 `shallowEqual`。
+
+`ui-slots` 引用 store contract，`ui-renderer` 管理 store instance 并提供 `useStore`。
+
+Store 只承载 draft、View selection、Chat selection、inspection request 和面板尺寸等观看或交互状态。Session、Workspace、Conversation、Remote stream 和 connection generation 不进入 Store。
+
+### 注册与释放顺序
+
+一个 plugin 同时提供 source 与 Slot entry 时，先注册 source，再注册 entry。Cordis 反向 disposal 先移除 entry，再移除 source，仍挂载的 entry 因而不会短暂失去必需 hook。
+
+Session binding 释放通过 `binding.ctx.effect()` 清理 UI materialization 与 scoped store。Plugin fiber 释放通过 registration disposer 清理 source、listener 和 Slot entry。
+
+所有 disposer 都可重复调用，不依赖 Cordis 生命周期以外的隐式回调。
+
+## 组合与依赖方向
+
+应用 bundle 显式安装所需 Controller、adapter、target 和 renderer plugin。每个 owner 的 `apply()` 只安装自己的 service、listener 和 contribution。
+
+运行时消费方向是 `session-controller → ui-session → ui-conversation → target UI`、`workspace-controller → ui-workspace` 和 `store → ui-slots → ui-renderer`；Approval 与 Question 只依赖 `ui-session` 提供的 pending 注册点。
+
+图中的箭头表示运行时消费关系，不覆盖 type-only declaration merge 边。Controller 不反向依赖 UI adapter，renderer 不反向依赖领域 package，Conversation core 不依赖具体 target。
+
+UI component 不接收 `ctx`。跨 package 协作使用 Cordis service、standard source 或 Slot registration，不新增聚合 facade。
+
+## 开发者遵循方式
+
+### 先确定数据 owner
+
+新增状态前先按消费语义确定唯一 owner：Host 通信、命令和实体生命周期归 API Controller；由 Session events 形成且与 target 无关的数据归 Conversation core；只服务一种 View 的投影归对应 target package；草稿、选择和面板状态归拥有该交互的 UI package。
+
+同一事实不得同时保存在 Controller snapshot、Conversation snapshot 和 Store。需要跨域决策时读取多个 source 并立即发出 command，不创建联合 snapshot，也不缓存另一领域的对象副本。
+
+以下信号表示 owner 选择错误：Controller 开始 import React；renderer 出现业务类型分支；组件遍历 Session events；Store 保存 Session 或 Workspace 实体；一个 target 的变化要求修改 Session Controller。
+
+### 新增 Session-scoped 数据
+
+1. 在领域 owner 中提供 React-free observable source。
+2. 在所属 UI adapter 中 declaration-merge 标准 prop 类型。
+3. 通过 `ctx.uiSession.provide()` 声明固定 roster，并从 Session binding 解析 source。
+4. 让 Slot component 从 `PropsRuntime` 获得生成的 hook，不向组件传 `ctx`。
+5. 把每个 binding 的资源清理挂到 `binding.ctx.effect()`，把 registration 清理留给 plugin fiber。
+6. 测试缺失值、重复名字、roster 替换、Session 切换和 binding disposal。
+
+只有开放 key 空间使用 keyed hook；有限且稳定的 source 使用普通 hook；不会变化的标识使用 prop。不得为了减少一次注册而把业务名称硬编码进 renderer。
+
+### 新增 Conversation target
+
+1. 在 target package 中扩展 Conversation snapshot 或 location data map。
+2. 向 `UiConversation.events` 注册所需 event Definition。
+3. 向 `UiConversation.views` 注册 snapshot builder、target id、View 与 activity 规则。
+4. 通过 `ctx.uiSession.provide()` 暴露该 target 的标准 selector hook。
+5. 在同一 package 中注册 renderer、locale 和 target-specific Slot entry。
+6. 验证 target 卸载只重建 Conversation binding，不改变 Session、其他 target 或 Remote stream。
+
+Target 不得读取另一个 target 的 snapshot 作为自己的数据源。可选协作通过窄 port 或 Slot 完成；缺失 target 时，shell 必须保持可启动且不得猜测 fallback。
+
+### 新增 pending-interaction 业务
+
+1. 业务 package 定义 Pending 对象及其完成、取消和中止语义。
+2. 通过 declaration merge 把对象加入 `SessionPendingInteractionMap`。
+3. 在 `apply()` 中调用 `registerPendingInteraction()` 一次，并注册唯一稳定的 composer entry。
+4. Remote waterfall listener 从 Agent Context 解析 Session；无法处理时调用 `next()`。
+5. 可处理时创建 Pending 对象，使用 publication function 发布，等待结果，并在 `finally` 中移除。
+6. 测试并发 key、precedence、用户取消、transport abort、plugin disposal 和无 Session delegation。
+
+单次请求不得注册 Slot、声明 child Slot、修改 Session snapshot 或另建状态索引。Sidebar 与 composer 都从 `useSessionPendingInteraction` 读取同一个 effective object。
+
+### Review 检查点
+
+- 每个新 source、registry contribution、listener 和 cache 都有明确 Cordis fiber 或 Session binding owner。
+- 每个公共 hook 能追溯到唯一 React-free source；不存在只为传参而层层转发的 selector。
+- 每个 component 的数据与 action 都来自标准 props 或所属 Slot inject face。
+- 每个 target 在缺席、动态注册和卸载时都有定义明确的结果。
+- 每个跨层 import 都沿 Controller、adapter、renderer、component 的单向关系前进。
+- 每个错误由最早能解释其语义的 owner 归类；载体错误不直接泄漏成业务错误。
+
+## 验证
+
+各 owner 的测试分别固定 Controller binding 与 event source、UI scope 与 pending precedence、Conversation 增量组装与 View fallback、target projection、waterfall 结果以及 renderer 的 scope/store 生命周期。应用组装测试同时覆盖完整 roster 和缺少具体 target 的启动；组件测试不替代对象层、重放和生命周期测试。
+
+## 备选方案
+
+- **保留 Runtime facade。** 它维持单一入口，却继续形成依赖汇点并允许新代码绕过领域 owner；系统因此不保留 facade 或兼容出口。
+- **把所有 Client 状态放进 API Controller。** 这会让协议对象承担 React、View 和 presentation policy；Controller 因而只保留无 React 的领域状态。
+- **让 Controller 直接提供 React hooks。** 这会阻止非 React 消费者复用同一对象，也使 transport 与 renderer 生命周期相互依赖。
+- **把 Conversation 放进 SessionSnapshot。** 这会扩大 Session API，并迫使普通 Session 消费者理解 event folding 与 target roster。
+- **让 Chat 和 Trajectory 各自重放 Session events。** 这会重复维护顺序、location 和 registry rebuild；共享 assemble core 因而留在 `ui-conversation`。
+- **把 Conversation core 拆成额外的非 UI package。** Core 与 adapter 当前共同演化且没有其他非 UI package 消费者；同包目录隔离足以保持 React-free core。
+- **把 Workspace 与 Session 合成联合 snapshot。** 这会制造新的跨域 owner；跨域逻辑保留为 `ui-workspace` 的即时决策。
+- **让 renderer 内建所有标准 hook。** 这会要求通用基础设施认识每个领域；standard source registration 保持 renderer 与业务类型解耦。
+- **让每个 pending 请求动态注册 composer entry。** 这会重复声明 child Slot，并让并发请求竞争注册顺序；稳定 entry 与请求期对象发布保持分离。
+- **把 pending interaction 写回 Session projection。** 待回答 waterfall 不是已提交的持久 Session 事实，刷新恢复由 Remote Event replay 负责，因此它留在业务 UI source。
+- **为 binding 增加专用 release callback。** 这会重复 Cordis 生命周期；`binding.ctx.effect()` 已能把消费者清理挂到同一 owner。
+- **让 SessionProvider 通过 render function 传 Session id。** 这会产生另一条数据注入路径；普通 children 与标准 `sessionId` prop 保持 scope 数据只有一个入口。
+- **把 Store 留在 renderer。** Store contract 不依赖 React，并被对象与测试基础设施复用；独立 `client/store` 保持 engine 与渲染生命周期分离。
+
+## 后果
+
+Session、Workspace、Conversation 与具体 target 各自拥有一份权威状态，非 React consumer 可以直接复用 Controller 和 assemble core。新增 Conversation target 只需注册 Definition、builder、View、标准 source 和 Slot entry；新增 pending-interaction 业务只需声明类型、注册 domain 并提供稳定 composer entry。
+
+Renderer 和 Session Controller 不因新增业务领域而增加分支，Session binding 与 plugin fiber 则提供两条明确且可组合的释放路径。UI 可以观察到 Session 与 Conversation source 的独立发布，消费者不得依赖二者的通知顺序。
+
+组合包必须显式装载所需 adapter 与 target plugin。缺失具体 target 时 shell 仍可运行，但不会生成或猜测该 target 的 View。更多 package 和显式注册增加了装配工作，但依赖方向、测试范围与故障 owner 均可局部确定。

 ## Problem
 
-Provider-side diagnosis needs the exact active plugin package versions that produced an official DeepSeek request. The existing browser-facing plugin inventory reports configured Loader rows and lifecycle phases but owns neither package-manifest resolution nor the requesting agent's standing preset composition.
+The canonical Session log contains request boundaries, raw response chunks, assembled messages, tool activity, plugin events, and failure facts that the model message list does not preserve. The OTel session-telemetry path projects and batches that log independently of model requests, uses deployment-selected sharing modes, and intentionally drops most assistant chunks. DeepSeek's official API therefore cannot reconstruct the complete harness trajectory from its ordinary request messages or the telemetry feed.
 
-This metadata belongs only on the official DeepSeek adapter path. Adding it to `GenerateOptions` or the provider-neutral LLM seam would expose a DeepSeek wire concept to pi-ai and every future adapter.
+Provider-side diagnosis also needs the exact active plugin package versions that produced a request. The existing browser-facing plugin inventory reports configured Loader rows and lifecycle phases but owns neither package-manifest resolution nor the requesting agent's standing preset composition.
 
-The adapter also needs one plugin-owned extension point. Importing Loader, preset, and package-manifest logic directly into `llm-deepseek` would make the transport own metadata discovery and prevent independent request fields from evolving as plugins.
+Both values belong only on the official DeepSeek adapter path. Adding them to `GenerateOptions` or the provider-neutral LLM seam would expose DeepSeek wire concepts to pi-ai and every future adapter.
 
 ## Decision
 
-`@deepseek-ai/dsh-deepseek-llm-api-extensions` registers `ctx.deepseekLlmApiExtensions`, an additive registry of top-level fields for `deepseek-official` request bodies. A contributor claims one declaration-merged field with `register()`. The adapter invokes `prepare()` after serializing the exact wire messages, passes the request cancellation signal, rejects preparation or base-field collision before HTTP, merges the detached fields, and calls the captured `accept()` transaction after HTTP 2xx. The registry stops awaiting preparation after cancellation even if a contributor ignores the signal. Acceptance failures remain request failures under `REQUEST_EXTENSION`; transport and non-2xx failures never accept a contribution. A composition without the registry retains the reusable base adapter.

+## Incremental session-log field
+
+`@deepseek-ai/dsh-session-log-deepseek` owns `dsh_session_log` as an explicit opt-in. When enabled, each request carrying a live Session id sends the contiguous canonical event suffix after the greatest durable `session-log-deepseek/delivery-accepted` watermark for that same Session identity. The field includes the immutable Session header and complete event envelopes. A 2xx appends a new watermark for the transmitted `throughSeq`; that event enters the following request's suffix. Forked logs retain parent watermark ids, so a child starts from sequence zero under its own identity. Concurrent acceptances may arrive out of order, and the maximum watermark remains authoritative. A process-local fold scans each Session event once and incrementally consumes later appends; a new Session object or HMR generation rebuilds the fold from durable history.
+
+The failure direction is at least once. A transport or provider rejection records no watermark. A crash after remote acceptance but before the watermark persists causes replay after resume, never a skipped sequence. Existing session checkpoints persist the event; the upload plugin owns no second store.
+
+The `events` array contains complete canonical `SessionEvent` objects directly. The sender copies every present event member without projection or redaction; the field is self-contained and requires no reconstruction against `messages`.

 ## Alternatives considered

+**Add generic metadata to `GenerateOptions` or `ctx.llm`.** Rejected because the values and acceptance timing are DeepSeek wire semantics; a provider-neutral request would make every adapter understand or ignore foreign fields.
+
+**Hard-wire the two producers into `llm-deepseek`.** Rejected because the adapter would import Session, Loader, preset, package-manifest, and cursor logic. The registry keeps transport responsible only for field merge and HTTP acceptance.
+
+### Why not request-relative message references?
+
+A recursive tagged representation could replace exact event-string ranges with paths and UTF-8 byte offsets into the containing request's `messages`. Measurement used Node v24.16.0 on macOS arm64 and the three largest available local Zstandard Session artifacts, whose compressed artifact sizes were 2,437,052, 572,602, and 118,811 bytes. Late-enable replay used each final completed request boundary; steady replay covered 411 completed boundaries. The byte counts cover complete minified DeepSeek requests.

+| Steady state | 389,295,815 B | 387,180,848 B | 0.54% | 285.0 s total |
+
+The three late-enable calls took 470.5, 29.4, and 0.158 seconds. Only 701 of 115,071 events (0.61%) selected references. A hypothetical level-6 whole-request gzip comparison reduced raw request bytes by 89.38% for late enable and 73.42% for steady state; message references added 21.68% and 0.59% respectively after gzip.
+
+The receiver would also need to traverse the tagged tree, resolve paths into the exact request messages, validate UTF-8 ranges, and reconstruct every referenced event. Even treating that receiver cost as zero, the steady-state byte saving, synchronous sender cost, and dependence on another request field do not justify a versioned wire format.
+
+### Why not omit assistant chunks or overlapping event data?
+
+About 98% of the measured real-session events were `assistant/chunk`. Omitting chunks after reference encoding reduced the complete identity JSON by another 84.79% for late enable and 6.49% for steady state, but it prevents lossless canonical-log reconstruction and leaves `assistant/message.sourceEventSeqs` pointing to absent events. Fuzzy or normalized substitutions have the same reconstruction defect.
+
+**Keep the upload cursor only in memory.** Rejected because a normal process restart would resend the entire Session. A canonical acceptance event makes restart recovery best-effort durable without another storage backend; the remaining crash window produces allowed duplicates.
 
 **Inventory every live Cordis fiber.** Rejected because programmatic and in-memory fibers have no authoritative npm package provenance. Loader-backed host and preset entries provide exact resolvable package identity.

 ## Consequences
 
-Official DeepSeek requests carry active package versions to their resolved `baseURL`, including configured gateways. The field is model-hidden and adds no prompt tokens or KV-cache changes. Manifest resolution, field collision, acceptance handling, or provider schema rejection fails the model request rather than silently dropping metadata.
+Official DeepSeek requests carry active package versions to their resolved `baseURL`, including configured gateways. An explicit Session-log opt-in also carries the complete newly unaccepted Session suffix. The fields are model-hidden and add no prompt tokens or KV-cache changes, but can substantially increase HTTP body size. Manifest resolution, field collision, acceptance logging, or provider schema rejection fails the model request rather than silently dropping metadata.

+The `delivery-accepted` event becomes part of the canonical log and is itself delivered on a later request. Crash recovery can duplicate a suffix but does not infer acceptance from assistant output or create a second local cursor store.

-Direct calls without a live Agent still carry the host package inventory. The [DeepSeek request-identity decision](../feature/2026-08-11-deepseek-request-user-id-header.md) continues to own user/session headers, which remain outside the body.

+# Agent Note: One dsh launcher for application profiles
+
+Status: implemented
+
+English | [中文](2026-08-22-single-dsh-application-launcher.zh.md)
+
+## Problem
+
+DeepSeek Harness application processes need one owner for composition, plugin resolution, environment discovery, shutdown, and user customization. A dedicated app bin with a complete `cordis.yml` creates a second lifecycle beside profile launch: plugins installed into a profile do not reach it, behavior drifts from `dsh-base`, and SDK callers learn arbitrary process argv instead of the product's composition model.
+
+The Python SDK distributes a native executable and three platform wheels whose embedded direct-config runtime cannot change launch architecture without rebuilding and validating the complete VFS closure. That distribution needs an explicit temporary exception, not a second general Node application pattern.
+
+## Decision
+
+### Launch scope
+
+Every supported Node application starts through the `dsh` CLI and one named profile. The shipped application commands are `dsh web`, `dsh --profile headless`, `dsh --profile sdk`, and `dsh --profile acp`; `dsh web` is the deliberate convenience alias for `--profile web`, not another application entry.
+
+Vendor CLIs, build-only and test-only executables, direct in-process plugin mounting, and the private browser WebWorker preview are outside the application-launch inventory. A package app bin or root demo that launches a package entry is not an accepted extension point.
+
+### Profile applications
+
+`@deepseek-ai/dsh-sdk-app` and `@deepseek-ai/dsh-acp-app` compose the protocol applications over `@deepseek-ai/dsh-base`. The SDK bundle adds the JSON-RPC server plus app-owned help and stdio lifetime; the ACP bundle adds the automation-only ACP server plus the same application responsibilities. Both adopt the base model, tools, persistence, settings, credentials, policy, and environment behavior.
+
+Profile manifests own patch reload:
+
+| Profile | `patchReload` |
+|---|---|
+| `web` | `live` |
+| `headless` | `startup` |
+| `sdk` | `startup` |
+| `acp` | `startup` |
+
+Custom profiles default to `live`. A startup profile still applies its bundle, profile, home-level, and invocation `--patch` layers, but it does not watch them after boot. `dsh-base` inserts the module-HMR row disabled; a profile with a tested source-module reload lifecycle must enable it explicitly. None of the shipped profiles enable server module HMR: `patchReload: live` uses the launcher's config-only watcher while the startup profiles install no watcher. SDK and ACP cannot safely replace their server, agents, persistence, or tool registry inside one owned stdio connection.
+
+The shipped protocol profiles reserve stdout for protocol frames, expose help without starting transport, and route stdin EOF and signals through bounded root disposal. ACP remains automation-only. The SDK JSON-RPC methods, notification fields, and `initialize.serverInfo.name` remain stable. Model-visible tool and persistence defaults come from `dsh-base`, and runnable snapshots own those assembled application outputs.
+
+### TypeScript SDK customization
+
+`@deepseek-ai/dsh-sdk-client` depends on the same-version `@deepseek-ai/dsh` package, resolves its installed CLI module, runs it through the current Node executable, and selects `sdk` by default. Both client layers expose `dshBin`, `profile`, ordered `patches`, `dshHome`, process cwd, environment, and timeouts; arbitrary command/argv launch remains an internal fake-runtime adapter.
+
+SDK users customize plugins through profiles. `dsh plugin --profile <name> ...` manages persistent dependencies and bundle order, the profile's `cordis.patch.yml` owns persistent row changes, and launch `patches` supply ordered ephemeral overrides. A custom profile must retain `@deepseek-ai/dsh-sdk-app` or another SDK server row. Relative CLI-module, patch, explicit home, and process-cwd paths become absolute before spawn, and initialization has a finite bound whose diagnostic names the selected profile.
+
+Direct SDK use follows normal Harness-home resolution: explicit `dshHome`, inherited `DSH_HOME`, then `~/.dsh`. `subagent-dsh-sdk` instead requires an explicit absolute home, so a nested runtime cannot discover a person's profiles, installed plugins, credentials, or sessions through the operating-system home. DSH-specific ACP child examples also pass an isolated home; the ACP backend itself remains generic for non-DSH agents.
+
+### Python exception and names
+
+The Python SDK's direct-config application lives in the private `packages/sdk/python-runtime` package named `@deepseek-ai/dsh-sdk-python-runtime`. Its only packaged executable entry is `lib/packaged-bin.js`, consumed by the private `dsh-sdk-python-runtime-closure` deploy root. It has no public npm bin. The runnable direct Python example is `examples/python-sdk-agent`.
+
+Python-observable behavior remains fixed: Python API, SDK wire, default `cordis.yml`, environment variables, wheel distribution names, packaged executable names, sidecar names, explicit runtime options, zero-config behavior, and supported platforms. The stable SDK family remains `@deepseek-ai/dsh-sdk-client`, `@deepseek-ai/dsh-sdk-protocol`, `@deepseek-ai/dsh-sdk-jsonrpc-server`, and wire identity `deepseek-harness-sdk-runtime`; `@deepseek-ai/dsh-acp` remains the ACP protocol plugin. There is no compatibility package, forwarding executable, fallback parser, or SDK/ACP launcher alias.
+
+### Enforcement
+
+`verify-application-entrypoints` scans application/package manifests, executable sources, and root demo scripts. The allowlist classifies the `dsh` product bin, vendor-excluded scope, the private WebWorker build tool, test support, and the private Python carrier. An unclassified shebang, a new package bin, or a demo wrapper that bypasses `apps/cli/src/bin.ts` fails hygiene and the primary/static CI aggregates.
+
+## Deferred Python migration
+
+The Python runtime follow-up must move the packaged process through `dsh --profile sdk`, preserve the wheel's closed dependency and native sidecar behavior, and delete `@deepseek-ai/dsh-sdk-python-runtime`. Only after those conditions pass on Linux x64, Linux arm64, and macOS arm64 does the executable family change from `dsh-jsonrpc-agent-pkg-<platform>-<arch>` to `deepseek-harness-sdk-runtime-<platform>-<arch>`. The temporary carrier and current artifact names make that obligation visible without weakening current Python compatibility.
+
+## Existing decisions and supersession
+
+This decision supersedes the application-launch and package-name facts in [profile plugin bundles](2026-08-05-profile-plugin-bundles.md), [TypeScript SDK client and subagent backend](../feature/2026-07-27-typescript-sdk-and-sdk-subagent-backend.md), [remove the SDK project toolchain](../simplification/2026-08-11-remove-sdk-project-toolchain.md), and [single-file Python SDK runtime distribution](2026-07-10-single-file-executable-sdk-runtime-distribution.md). Those notes retain independent authority for profile layering, client/wire semantics, deleted project tooling, and native packaging.
+
+The [ACP automation-only protocol](../simplification/2026-07-23-acp-automation-only-protocol.md) remains authoritative for ACP wire and interaction scope. The [repository naming contract](2026-08-11-repository-naming-contract-and-rename-ledger.md) remains authoritative for role-based package names. No active note is fully superseded or eligible for archival.
+
+## Alternatives considered
+
+**Keep direct bins and state that profiles are preferred.** Rejected: documentation cannot make profiles own plugin installation, environment loading, shutdown, and tests while a supported executable bypasses them.
+
+**Keep forwarding compatibility bins.** Rejected: a forwarding executable remains another public launch name and compatibility promise. The pre-release repository can move callers directly to profiles.
+
+**Put complete standalone Cordis trees behind profile wrappers.** Rejected: that centralizes argv without centralizing application composition. `dsh-base` plus thin app bundles gives shared policy one owner while retaining protocol-specific negative guarantees.
+
+**Accept inline plugins or a complete `cordis.yml` in the TypeScript constructor.** Rejected: the SDK would become another package installer and application composer. Named profiles and patch files already provide persistent and per-launch customization through one resolution model.
+
+**Resolve `dsh` only from `PATH`.** Rejected: ordinary Node processes do not reliably inherit a project-local `.bin` path. A same-version package dependency provides a deterministic runtime.
+
+**Enable module HMR in `dsh-base` and make unsafe profiles disable it.** Rejected: the shared base also underlies custom profiles, so an enabled default makes every new application remember to opt out of source-module replacement. A disabled base makes module HMR an explicit profile capability while leaving `patchReload: live` config watching available.
+
+**Hot-reload protocol profiles.** Rejected: replacing a protocol server or its dependencies can invalidate pending frames and SDK-owned agents. Process restart is the adoption boundary for SDK and ACP configuration changes.
+
+**Move the Python executable through profiles without a separate packaging proof.** Rejected: the native VFS closure, three platform wheels, ripgrep and spawn-helper sidecars, default config discovery, and clean-install behavior require their own migration evidence.
+
+## Verification
+
+- Source and built CLI acceptance cover `sdk` and `acp` help, transport startup, stdout purity, EOF, signals, and root disposal.
+- Bundle configuration tests pin module HMR disabled in `dsh-base` and absent from shipped mode overrides; the custom live-profile e2e pins config reload through the launcher's watch-only fallback.
+- Focused unit suites cover profile launch resolution, initialization bounds, SDK retries, server readiness, and nested isolated homes with 100% coverage on the changed runtime sources.
+- Keyless ACP and SDK snapshots boot real `dsh` profiles and pin protocol output plus persisted logs; the nested SDK composition boots a second real profile runtime.
+- The real-API workflow caps file parallelism at four because one profile e2e file can own several complete `dsh` subprocess trees; workflow tests pin that resource bound.
+- The Python suite exercises exe and node carriers; all packaged-runtime scenarios, native macOS executable construction, both wheels, and clean-wheel default/MCP smokes retain the existing artifact names.
+- `verify-application-entrypoints` includes invalid fixtures for package bins, executable sources, package-launching demo wrappers, and unclassified demos.
+
+## Consequences
+
+- A user changes an SDK application's plugin composition through a named profile and ordered patches, using the same installation and resolution model as every other dsh application.
+- A custom profile receives live config watching without server module HMR and opts into source-module replacement only through an explicit row override.
+- SDK and ACP share the complete base application and one set of policy and tools; snapshots present intentional assembled differences explicitly.
+- Adding `@deepseek-ai/dsh` increases the TypeScript client's install size in exchange for a deterministic same-version runtime.
+- Trusted user patches can add a plugin that writes to stdout and corrupt their own protocol stream; shipped profiles guarantee purity, not arbitrary third-party composition.
+- Python keeps a visibly private, narrowly allowed direct-config carrier until its platform artifact migration is independently proven.

+# Agent Note: 由一个 dsh 启动应用 profile
+
+Status: implemented
+
+[English](2026-08-22-single-dsh-application-launcher.md) | 中文
+
+## Problem
+
+DeepSeek Harness 应用进程需要由同一个机制负责组合、插件解析、环境发现、关闭和用户自定义。带完整 `cordis.yml` 的专用应用 bin 会在 profile 启动之外形成第二套生命周期：安装到 profile 的插件无法到达它，行为会与 `dsh-base` 偏离，SDK 调用方还需要学习任意进程 argv，而不是产品的组合模型。
+
+Python SDK 分发一个原生可执行文件和三个平台 wheel 包；其中嵌入的直读配置运行时只有在重建并验证完整 VFS 闭包后才能改变启动架构。该分发需要一个明确的临时例外，而不是另一种通用 Node 应用模式。
+
+## Decision
+
+### 启动范围
+
+所有受支持的 Node 应用都通过 `dsh` CLI 与一个具名 profile 启动。随附应用命令是 `dsh web`、`dsh --profile headless`、`dsh --profile sdk` 与 `dsh --profile acp`；`dsh web` 是刻意为 `--profile web` 保留的便捷别名，不是另一个应用入口。
+
+Vendor CLI、仅用于构建和测试的可执行文件、进程内直接挂载插件以及私有浏览器 WebWorker 预览都不属于应用启动清单。包应用 bin 或直接启动包入口的根 demo 都不是可接受的扩展点。
+
+### Profile 应用
+
+`@deepseek-ai/dsh-sdk-app` 与 `@deepseek-ai/dsh-acp-app` 在 `@deepseek-ai/dsh-base` 之上组合协议应用。SDK 组合包增加 JSON-RPC 服务器、应用自有帮助和 stdio 生命周期；ACP 组合包增加仅用于自动化的 ACP 服务器与相同的应用职责。两者都采用 base 层的模型、工具、持久化、settings、credentials、策略和环境行为。
+
+Profile manifest 负责 patch 重载：
+
+| Profile | `patchReload` |
+|---|---|
+| `web` | `live` |
+| `headless` | `startup` |
+| `sdk` | `startup` |
+| `acp` | `startup` |
+
+自定义 profile 默认为 `live`。`startup` profile 仍会应用组合包、profile、home 级与调用时 `--patch` 各层，但启动后不会监视这些文件。`dsh-base` 插入的模块 HMR（热模块替换）配置项默认禁用；具有经过验证的源码模块重载生命周期的 profile 必须显式启用它。随附 profile 均不启用服务器模块 HMR：`patchReload: live` 使用启动器的仅配置 watcher，`startup` profile 则不安装 watcher。SDK 与 ACP 无法在一个自有 stdio 连接内安全替换其服务器、agent、持久化或工具注册表。
+
+随附协议 profile 将 stdout 保留给协议帧，显示帮助时不启动 transport，并通过有界根节点 dispose（资源释放）处理 stdin EOF 与信号。ACP 继续仅用于自动化。SDK JSON-RPC 方法、通知字段与 `initialize.serverInfo.name` 保持稳定。模型可见工具与持久化默认值来自 `dsh-base`，可运行快照负责钉住这些已组装的应用输出。
+
+### TypeScript SDK 自定义
+
+`@deepseek-ai/dsh-sdk-client` 依赖同版本的 `@deepseek-ai/dsh` 包，解析其已安装 CLI 模块，通过当前 Node 可执行文件运行该模块，并默认选择 `sdk`。两层客户端都暴露 `dshBin`、`profile`、有序 `patches`、`dshHome`、进程 cwd、环境和超时；任意 command/argv 启动只保留为 fake-runtime 测试的内部适配器。
+
+SDK 用户通过 profile 自定义插件。`dsh plugin --profile <name> ...` 管理持久依赖与组合包顺序，profile 的 `cordis.patch.yml` 负责持久配置项变更，启动时 `patches` 提供有序临时覆盖。自定义 profile 必须保留 `@deepseek-ai/dsh-sdk-app` 或另一个 SDK 服务器配置项。相对 CLI 模块、patch、显式 home 与进程 cwd 路径会在 spawn 前变为绝对路径；初始化具有有限时限，诊断会写明所选 profile。
+
+直接使用 SDK 时遵循普通 Harness home 解析：显式 `dshHome`、继承的 `DSH_HOME`，最后是 `~/.dsh`。`subagent-dsh-sdk` 则要求显式绝对 home，因此嵌套运行时不会通过操作系统 home 发现个人 profile、已安装插件、凭据或会话。DSH 专用 ACP 子进程示例同样传入隔离 home；ACP 后端自身继续适用于非 DSH agent。
+
+### Python 例外与命名
+
+Python SDK 的直读配置应用位于私有 `packages/sdk/python-runtime` 包，名称是 `@deepseek-ai/dsh-sdk-python-runtime`。它唯一的打包可执行入口是 `lib/packaged-bin.js`，由私有 `dsh-sdk-python-runtime-closure` 部署根消费。它没有公开 npm bin。可运行的直启 Python 示例是 `examples/python-sdk-agent`。
+
+Python 可观察行为保持不变：Python API、SDK 协议格式、默认 `cordis.yml`、环境变量、wheel 包分发名称、打包可执行文件名称、伴随文件名称、显式运行时选项、零配置行为与支持平台。稳定 SDK 包族继续是 `@deepseek-ai/dsh-sdk-client`、`@deepseek-ai/dsh-sdk-protocol`、`@deepseek-ai/dsh-sdk-jsonrpc-server`，协议 identity 继续是 `deepseek-harness-sdk-runtime`；`@deepseek-ai/dsh-acp` 继续作为 ACP 协议插件。仓库不保留兼容包、转发可执行文件、后备解析器或 SDK／ACP 启动别名。
+
+### 强制校验
+
+`verify-application-entrypoints` 扫描应用／包 manifest、可执行源码和根 demo 脚本。允许清单对 `dsh` 产品 bin、排除的 vendor 范围、私有 WebWorker 构建工具、测试支持以及私有 Python 载体进行分类。未分类的 shebang、新包 bin 或绕过 `apps/cli/src/bin.ts` 的 demo wrapper 都会使 hygiene 与 primary／static CI 聚合失败。
+
+## 暂缓的 Python 迁移
+
+Python 运行时后续工作必须把打包进程迁移到 `dsh --profile sdk`，保持 wheel 包的封闭依赖与原生伴随文件行为，并删除 `@deepseek-ai/dsh-sdk-python-runtime`。只有这些条件在 Linux x64、Linux arm64 与 macOS arm64 全部通过后，可执行文件族才会从 `dsh-jsonrpc-agent-pkg-<platform>-<arch>` 改名为 `deepseek-harness-sdk-runtime-<platform>-<arch>`。临时载体与当前产物名称使这项义务清晰可见，同时不削弱当前 Python 兼容性。
+
+## 既有决策与取代关系
+
+本决策取代 [profile 插件组合包](2026-08-05-profile-plugin-bundles.zh.md)、[TypeScript SDK 客户端与 SDK subagent 后端](../feature/2026-07-27-typescript-sdk-and-sdk-subagent-backend.zh.md)、[移除 SDK 项目工具链](../simplification/2026-08-11-remove-sdk-project-toolchain.zh.md)和[单文件 Python SDK 运行时分发](2026-07-10-single-file-executable-sdk-runtime-distribution.zh.md)中的应用启动与包名事实。这些 Note 对 profile 分层、客户端／协议语义、已删除的项目工具链与原生打包仍分别具有独立权威。
+
+[ACP 仅自动化协议](../simplification/2026-07-23-acp-automation-only-protocol.zh.md)继续负责 ACP 协议格式与交互范围。[仓库命名约定](2026-08-11-repository-naming-contract-and-rename-ledger.zh.md)继续负责基于角色的包名。没有任何活跃 Note 被完全取代，也没有 Note 符合归档条件。
+
+## 考虑过的替代方案
+
+**保留直启 bin，只声明推荐 profile。** 拒绝：只要受支持的可执行文件仍然绕过 profile，文档就无法让 profile 真正负责插件安装、环境加载、关闭和测试。
+
+**保留转发兼容 bin。** 拒绝：转发可执行文件仍然形成另一个公开启动名称与兼容承诺。预发布仓库可以让调用方直接迁移到 profile。
+
+**把完整独立 Cordis 树放到 profile wrapper 后面。** 拒绝：这只集中 argv，没有集中应用组合。`dsh-base` 加轻量应用组合包让共享策略只有一个归属，同时保留协议专属的负面保证。
+
+**在 TypeScript 构造函数中接受内联插件或完整 `cordis.yml`。** 拒绝：SDK 会因此成为另一个包安装器和应用组合器。具名 profile 与 patch 文件已通过统一解析模型提供持久与逐次启动自定义。
+
+**只从 `PATH` 解析 `dsh`。** 拒绝：普通 Node 进程不一定继承项目本地 `.bin` 路径。同版本包依赖可以提供确定的运行时。
+
+**在 `dsh-base` 中启用模块 HMR，再由不安全的 profile 逐一禁用。** 拒绝：共享 base 同样承载自定义 profile；默认启用会要求每个新应用都记得退出源码模块替换。base 默认禁用会让模块 HMR 成为显式的 profile 能力，同时保留 `patchReload: live` 配置监视。
+
+**热重载协议 profile。** 拒绝：替换协议服务器或其依赖可能破坏待处理协议帧与 SDK 自有 agent。进程重启是 SDK 与 ACP 配置变更的采用边界。
+
+**不做独立打包证明就把 Python 可执行文件迁移到 profile。** 拒绝：原生 VFS 闭包、三个平台 wheel 包、ripgrep 与 spawn-helper 伴随文件、默认配置发现和干净安装行为都需要自己的迁移证据。
+
+## 验证
+
+- 源码与构建后 CLI 验收覆盖 `sdk` 和 `acp` 的帮助、transport 启动、stdout 纯净性、EOF、信号与根节点 dispose。
+- 组合包配置测试钉住 `dsh-base` 默认禁用模块 HMR，随附模式覆盖层不再重复该策略；自定义 live profile 的 e2e 钉住启动器仅监视 fallback 提供的配置重载。
+- 聚焦单元套件覆盖 profile 启动解析、初始化时限、SDK 重试、服务器就绪和嵌套隔离 home，并对变更后的运行时源码实现 100% 覆盖率。
+- 免密钥 ACP 与 SDK 快照启动真实 `dsh` profile，并钉住协议输出与持久化日志；嵌套 SDK 组合会启动第二个真实 profile 运行时。
+- 真实 API 工作流把文件并行度限制为 4，因为一个 profile e2e 文件可能拥有多个完整 `dsh` 子进程树；工作流测试会钉住该资源上限。
+- Python 套件同时测试 exe 与 node 载体；全部打包运行时场景、原生 macOS 可执行文件构建、两个 wheel 包以及干净 wheel 默认／MCP 冒烟测试都保留既有产物名称。
+- `verify-application-entrypoints` 包含包 bin、可执行源码、直启包的 demo wrapper 与未分类 demo 等非法 fixture（测试前置数据）。
+
+## 影响
+
+- 用户通过具名 profile 与有序 patch 更改 SDK 应用的插件组合，使用与其他所有 dsh 应用相同的安装与解析模型。
+- 自定义 profile 可以在不启用服务器模块 HMR 的情况下获得实时配置监视，只有显式覆盖配置项才会启用源码模块替换。
+- SDK 与 ACP 共享完整 base 应用和同一份策略与工具；快照以显式差异呈现刻意采用的组装变化。
+- 增加 `@deepseek-ai/dsh` 会扩大 TypeScript 客户端的安装体积，换来确定的同版本运行时。
+- 受信任用户 patch 可以增加写入 stdout 的插件并破坏自己的协议流；随附 profile 保证纯净，不为任意第三方组合提供保证。
+- Python 保留一个清晰可见的私有直读配置载体，直到其平台产物迁移得到独立证明。

+
+## Problem
+
+Typed locale namespaces and bilingual dictionary parity proved that registered dictionaries were complete, but they could not prove that presentation code used them. JSX text, accessibility attributes, formatter returns, and zero-Cordis primitive defaults could bypass `t` while every locale check remained green. The deferred and supposedly language-neutral exceptions recorded in the [initial full-rollout decision](2026-07-30-client-locale-full-rollout.md) accumulated into a mixed-language UI, especially in trajectory inspection and generic Tool cards.
+
+## Decision
+
+**Locale dictionaries own all product-authored client UI wording.** Visible text, accessibility names, tooltips, placeholders, empty states, status labels, units, and formatting templates reach presentation through a typed `t` seat or an already-localized prop. A value authored by a user, model, provider, plugin, wire peer, or operating system remains data and renders verbatim; protocol tags, tool names, paths, URLs, JSON/JavaScript literals, and stable internal ids are not translated.
+
+**Cordis-free primitives require complete localized copy props and own no language fallback.** `MarkdownText`, `JsonTree`, `TerminalBlock`, `DiffBlock`, `ReadBlock`, `SearchBlock`, `WebBlock`, `CodeBlock`, `JsonBlock`, `HoverCard`, and `ConnectionBanner` receive their chrome from the feature render site. This preserves the primitive package's runtime independence while making omission a type error instead of silently selecting Chinese or English. Shared words live in the `common` namespace; feature-specific phrases stay with the feature that decides their meaning.
+
+**Localized display text is never an identity.** Models and stores retain discriminants, stable ids, and non-display markers. Renderers translate after matching, and request maps carry stable group membership into the trajectory ledger. A client-synthesized error that must survive in a view model uses a stable marker and is translated only when displayed. Language switching therefore changes wording without changing selection, grouping, search identity, or lifecycle state.
+
+**`verify-client-ui-i18n` enforces source ownership.** The TypeScript-AST check discovers every package `src/client` tree that contains TSX, all helper TS files under `packages/client/ui-*`, and the web app source. It rejects natural-language JSX text, copy-bearing attributes and component props, literal JSX branches, label/copy data, named copy helpers, string-returning display formatters, and destructuring defaults. Locale dictionary owners and immutable language tokens are the narrow syntactic exclusions. Discovery refuses a narrowed corpus, unit fixtures pin admitted and excluded forms, and the check runs in the static CI and `hygiene` graphs. Dictionary-key parity remains a separate check: one gate proves copy enters the locale path, while the other proves both shipped languages implement that path.
+
+The product-authored error and design-literal exclusions, primitive defaults, and trajectory deferral in the [initial rollout](2026-07-30-client-locale-full-rollout.md) are superseded by this decision. Its label-thunk, typed-seat, browser-locale, date-formatting, and search-placeholder decisions remain active.
+
+## Verification
+
+The AST check's own Vitest spec pins direct JSX, template branches, semantic copy props, label data, formatter returns, locale-key calls, structural attributes, and dictionary owners. Locale dictionary parity pins identical `zh`/`en` keys. Client component suites exercise both direct translated seats and locale-prop adapters, and the assembled web replay plus the required real-server GIF demonstrate the shipped locale switch on the actual trajectory surface.
+
+## Alternatives considered
+
+**Rely on review and AGENTS.md alone.** Rejected because the existing rule and typed dictionaries coexisted with hundreds of bypasses; reviewers need a source-level failure at the introducing line.
+
+**Use a text regex or ban every string literal.** Rejected because TypeScript and JSX contain imports, CSS classes, discriminants, event names, SVG data, and user/wire values. Syntax-aware contexts provide useful signal without an ever-growing file allowlist, while the minimum discovery count prevents a falsely green narrowed scan.
+
+**Keep primitive fallback copy for convenient direct use.** Rejected because a fallback is itself an implicit locale choice. Required label props keep primitives framework-free and make each product render site name its copy owner.
+
+**Translate every string that reaches the DOM.** Rejected because authored data and protocol/code tokens are not product wording. Translating them corrupts evidence, identifiers, commands, paths, URLs, and provider diagnostics; only surrounding product chrome belongs to the locale system.
+
+## Consequences
+
+- Adding or changing client UI copy requires a typed dictionary key in both locales and behavior evidence for the affected render path.
+- Pure primitives have larger explicit prop types, and tests provide deliberate label fixtures; this cost prevents hidden locale behavior.
+- The AST check catches authored literal bypasses but cannot prove that an arbitrary dynamic string prop was translated. Types, dictionary parity, component tests, and review still own that semantic distinction.
+- Boot markup that renders before the locale service and externally authored runtime data remain outside the dictionary path; product UI replaces boot copy after locale activation.

+# Agent Note: locale 归属的 client UI 文案
+
+Status: implemented
+
+[English](2026-08-23-locale-owned-client-ui-copy.md) | 中文
+
+## Problem
+
+typed locale namespace 与双语字典对等性可以证明已注册字典完整，却无法证明展示代码使用了字典。JSX 文本、无障碍属性、格式化函数返回值和 zero-Cordis 原子组件默认值都可能绕过 `t`，而全部 locale 检查仍保持绿色。[最初的全量接入决策](2026-07-30-client-locale-full-rollout.zh.md)中缓做或假定为语言无关的例外逐渐形成混合语言 UI，trajectory 检查面和通用工具卡尤为明显。
+
+## Decision
+
+**所有产品编写的 client UI 措辞都由 locale 字典持有。** 可见文本、无障碍名称、tooltip、placeholder、空状态、状态标签、单位和格式模板必须经 typed `t` 席位或已本地化 prop 到达展示层。由用户、模型、提供方、插件、wire 对端或操作系统编写的值仍是数据并原样渲染；协议 tag、工具名称、路径、URL、JSON/JavaScript 字面量和稳定内部 id 不翻译。
+
+**Cordis-free 原子组件要求完整的本地化文案 prop，且自身不持有语言回落值。** `MarkdownText`、`JsonTree`、`TerminalBlock`、`DiffBlock`、`ReadBlock`、`SearchBlock`、`WebBlock`、`CodeBlock`、`JsonBlock`、`HoverCard` 与 `ConnectionBanner` 的 chrome 均由功能渲染点传入。这样既保留原子组件包的运行时独立性，也让遗漏成为类型错误，而不是静默选择中文或英文。共享用词进入 `common` namespace；功能专属短语留在决定其语义的功能侧。
+
+**本地化展示文本绝不承担身份。** 模型与存储保留判别字段、稳定 id 和非展示 marker。渲染器先匹配再翻译，请求映射通过稳定的组成员关系进入 trajectory ledger。必须保存在视图模型中的 client 合成错误使用稳定 marker，只在展示时翻译。因此语言切换只改变措辞，不改变选择、分组、搜索身份或生命周期状态。
+
+**`verify-client-ui-i18n` 强制源码归属。** 基于 TypeScript AST 的检查会发现每个包含 TSX 的 package `src/client` 目录树、`packages/client/ui-*` 下的所有辅助 TS 文件和 web 应用源码；它拒绝自然语言 JSX 文本、承载文案的属性与组件 prop、JSX 字面量分支、label/copy 数据、具名文案辅助函数、返回字符串的展示格式化函数和解构默认值。locale 字典 owner 与不可变语言 token 是严格的语法级排除项。发现范围缩窄会直接失败，单元 fixture 固定纳入与排除形态，检查加入静态 CI 与 `hygiene` 图。字典 key 对等性仍由独立检查负责：一道门禁证明文案进入 locale 路径，另一道门禁证明两种发布语言都实现该路径。
+
+[最初接入决策](2026-07-30-client-locale-full-rollout.zh.md)中的产品自产错误与设计字面量例外、原子组件默认文案和 trajectory 缓做均由本决定取代；其 label thunk、typed 席位、浏览器 locale、日期格式化和搜索占位行决定仍有效。
+
+## Verification
+
+AST 检查自身的 Vitest spec 固定直接 JSX、模板分支、语义文案 prop、label 数据、格式化函数返回值、locale key 调用、结构属性和字典 owner。locale 字典对等性固定 `zh`/`en` key 一致。client 组件测试同时覆盖直接翻译席位与 locale prop 适配器；组装 web 回放和规定的真实服务器 GIF 在实际 trajectory 界面上展示发布的语言切换。
+
+## Alternatives considered
+
+**只依赖评审与 AGENTS.md。** 否决。既有规则和 typed 字典与数百个绕过点同时存在；评审者需要在引入行收到源码级失败。
+
+**使用文本正则，或禁止所有字符串字面量。** 否决。TypeScript 与 JSX 中包含 import、CSS class、判别值、事件名、SVG 数据和用户/wire 值。按语法上下文检查可在不扩张文件 allowlist 的情况下保持有效信号，而最小发现数量可防止扫描范围缩小后伪绿。
+
+**为方便直接使用而保留原子组件回落文案。** 否决。回落值本身就是隐式 locale 选择。必填 label prop 让原子组件保持框架无关，并迫使每个产品渲染点明确文案 owner。
+
+**翻译所有进入 DOM 的字符串。** 否决。外部编写的数据和协议/代码 token 并非产品措辞。翻译会破坏证据、标识符、命令、路径、URL 和提供方诊断；只有其周围的产品 chrome 属于 locale 系统。
+
+## Consequences
+
+- 新增或修改 client UI 文案时，必须在两种 locale 中添加 typed 字典 key，并为受影响渲染路径提供行为证据。
+- 纯原子组件的显式 prop 类型变大，测试需提供有意选择的 label fixture；这项成本换来无隐藏 locale 行为。
+- AST 检查可以抓到产品编写的字面量绕过，却无法证明任意动态字符串 prop 已翻译。类型、字典对等性、组件测试和评审仍共同负责这一语义区分。
+- locale 服务之前渲染的 boot 标记和外部编写的运行时数据仍在字典路径之外；locale 激活后，产品 UI 会替换 boot 文案。

 The lane's Chromium cannot synthesize any non-wheel device scrolling, which bounds what the e2e can drive for real: `Input.synthesizeScrollGesture` with a touch source and hand-rolled `Input.dispatchTouchEvent` sequences deliver DOM events but never move a scroller (headless and headed-under-Xvfb alike); the `default` gesture source synthesizes wheel events; and compositor scrollbars ignore synthetic mouse input entirely, with a gutter visible only when `--hide-scrollbars` is removed. Keyboard is the one working non-wheel primitive, so it carries the real-input-pipeline proof, and the fling scenario replays touch's signature — per-frame decaying displacements the component never authored — through the scrollport directly.

+# Agent Note: Win32 folder-picker paths stop truncating at U+XX00 code units
+
+Status: implemented
+
+English | [中文](2026-08-23-win32-utf16-nul-truncation.zh.md)
+
+## Problem
+
+`readUtf16` in `packages/host/directory-picker-native/src/win32-dialog-bindings.ts` translated the `IFileOpenDialog` result buffer by scanning for a zero byte with `bytes[end] !== 0`. UTF-16LE encodes NUL as two zero bytes, so any BMP code unit whose low byte is zero — U+XX00, such as 开 (U+5F00) — ended the scan early. Selecting a folder like `C:\Users\XIAOPAN\Desktop\安卓开发` returned `C:\Users\XIAOPAN\Desktop\安卓`, and the workspace-creation call failed with `workspace-invalid-path ... ENOENT`.
+
+## Decision
+
+The scan ends only when both bytes of a code unit are zero, still advancing two bytes at a time over the same 32KiB `koffi.view` buffer. A regression test drives `readUtf16` through the existing fake koffi COM world with a path containing 安卓开发 (U+5F00), so the termination rule is proven without a real Windows host.
+
+The fix is adopted verbatim from the community patch series on the `fix/win32-utf16-nul-truncation` branch of the ericcaiwx-star fork — [c8aac14703](https://github.com/ericcaiwx-star/deepseek-harness/commit/c8aac14703a517b8db1573f9ca4ed94dc58e276b) for the scan fix and [e1d6265cb9](https://github.com/ericcaiwx-star/deepseek-harness/commit/e1d6265cb930a0a74cba03c40e73ed872a83575f) for the fixture cleanup — reported in [discussion #580](https://github.com/deepseek-ai/deepseek-harness/discussions/580) (earlier reported in [discussion #563](https://github.com/deepseek-ai/deepseek-harness/discussions/563)). Both cherry-picks retain the original author, ericcaiwx-star; the upstream fork is the source of record for the patch.
+
+## Alternatives considered
+
+**Reject the community patch and rewrite the scan locally.** Rejected: the patch is minimal, fits the dialog's existing test approach, and a byte-identical cherry-pick preserves provenance and credit.
+
+**Decode the whole buffer with `toString('utf16le')` and split at `\0`.** Rejected: it copies the entire buffer instead of scanning, and the split would still depend on the same two-zero-byte rule.
+
+**Ask COM or koffi for a string length.** Rejected: the binding surface provides no length; the double-zero scan is the standard UTF-16LE NUL test.
+
+## Consequences
+
+- Any path containing a U+XX00 code unit survives the picker translation; paths with such characters (for example Chinese folder names) can be selected and used to create workspaces.
+- The fix changes no ABI usage, buffer size, or dialog flow; the COM child-process architecture in the [Win32 folder dialog note](../feature/2026-08-02-win32-in-process-folder-dialog.md) is untouched.
+- Real-dialog rendering and selection remain a manual Windows check; this change's regression test exercises only the byte-to-string translation against the fake COM world. The fixture path is synthetic (`C:\fixture\安卓开发`) so no real user path appears in the repository.

+
+Status: implemented

+[English](2026-08-23-win32-utf16-nul-truncation.md) | 中文
+
+## 问题
+
+`packages/host/directory-picker-native/src/win32-dialog-bindings.ts` 的 `readUtf16` 用 `bytes[end] !== 0` 扫描 `IFileOpenDialog` 结果缓冲区来寻找零字节。UTF-16LE 真正的 NUL 是两个零字节，因此任何低字节为 0 的 BMP 码元——U+XX00，例如「开」(U+5F00)——都会提前结束扫描。选择 `C:\Users\XIAOPAN\Desktop\安卓开发` 这类目录会得到 `C:\Users\XIAOPAN\Desktop\安卓`，随后创建工作区的调用以 `workspace-invalid-path ... ENOENT` 失败。
+
+## 决策
+
+扫描只有在一个码元的两个字节都为零时才结束，仍按每次两个字节在同一个 32KiB `koffi.view` 缓冲区上推进。回归测试通过既有的假 koffi COM 世界驱动 `readUtf16`，路径包含「安卓开发」(U+5F00)，从而不依赖真实 Windows 主机验证终止规则。
+
+修复逐字采用 ericcaiwx-star fork 的 `fix/win32-utf16-nul-truncation` 分支上的社区补丁系列——[c8aac14703](https://github.com/ericcaiwx-star/deepseek-harness/commit/c8aac14703a517b8db1573f9ca4ed94dc58e276b) 是扫描修复，[e1d6265cb9](https://github.com/ericcaiwx-star/deepseek-harness/commit/e1d6265cb930a0a74cba03c40e73ed872a83575f) 是 fixture 清理——在 [discussion #580](https://github.com/deepseek-ai/deepseek-harness/discussions/580) 报告（更早在 [discussion #563](https://github.com/deepseek-ai/deepseek-harness/discussions/563) 报告）。两次 cherry-pick 均保留原作者 ericcaiwx-star；上游 fork 是补丁的记录来源。
+
+## 考虑过的替代方案
+
+**拒绝社区补丁，本地重写扫描。** 拒绝：补丁极小，与目录选择器现有测试方式一致；逐字节一致的 cherry-pick 保留来源与署名。
+
+**用 `toString('utf16le')` 解码整个缓冲区再按 `\0` 切分。** 拒绝：复制整个缓冲区而非扫描，且切分仍依赖同一「双零字节」规则。
+
+**向 COM 或 koffi 索取字符串长度。** 拒绝：绑定面不提供长度；双零扫描是标准的 UTF-16LE NUL 判定。
+
+## 后果
+
+- 任何含 U+XX00 码元的路径组件都能通过选择器转译；含这类字符的路径（例如中文目录名）可以选中并用于创建工作区。
+- 修复不改变 ABI 用法、缓冲区大小或对话框流程；[Win32 目录选择器 note](../feature/2026-08-02-win32-in-process-folder-dialog.zh.md) 中的 COM 子进程架构不受影响。
+- 真实对话框渲染与选择仍是手动 Windows 检查；本次回归测试只针对假 COM 世界中的字节到字符串转译。fixture 路径为合成路径（`C:\fixture\安卓开发`），仓库中不出现真实用户路径。

 A deployment can combine depth and filtering, but the numeric cap does not synthesize a filter. The delegation tool stays visible at the cap because authorization may depend on runtime state; every attempted start checks the calling agent's current durable and runtime depth, and a rejected start returns an errored tool result without publishing a child. A deployment may separately deny delegation tools in children when its visibility policy is static. Neither choice changes the provider's conversation-history behavior.

 ## Consequences
 
-- TUI exposes one Codex-shaped `/goal` command supplied by a removable plugin.
+- TUI and non-Web base compositions expose one Codex-shaped `/goal` command supplied by a removable plugin; Web presets expose it only where they mount the producer.
 - Human status distinguishes durable phase from live activation and reports the exact goal-round cap.
 - Direct pause, resume, clear, creation, and edit consume no model turn while their accepted mutations remain reconstructable from the session log.
 - Restored sessions wait for a human decision; `/goal resume` is the literal command path, while an ordinary prompt in any language may authorize the model tool path.

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

The launch interface resolves the same-version `@deepseek-ai/dsh` dependency and selects a named profile, with optional `dshBin`, ordered patches, an explicit Harness home, process cwd, environment, and timeouts; arbitrary command/argv launch remains an internal fake-runtime adapter. A clean checkout without `lib/bin.js` uses that package's source entry through an absolute `tsx/esm` loader and an internal patch that omits build-generated Typert contribution loading, which the SDK protocol does not consume. `env` replaces rather than merges and is read when `start()` spawns, so callers own credential policy and can finish preparing it before first use. `RunResult` carries the structured `reason` (Python exposes only `status`); teardown walks a private stdin-EOF → SIGTERM → SIGKILL ladder to actual exit (the client runs outside any harness context, so it cannot ride `ctx.subprocess`).

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

 ## Testing
 
 Four tiers, per [testing policy](../../../../docs/testing.md):
 
 - **Keyless unit** — `sdk-client` drives a scripted fake runtime (`tests/fake-runtime.ts`, env-scripted, protocol-only — the Python `test_client.py` pattern) over real stdio; `subagent-dsh-sdk` drives the same fake through the real provider. 100% per-file coverage on all three packages.
-- **Keyless Loader composition** — `subagent-dsh-sdk/tests/loader-composition.e2e.ts` boots a test-only cordis.yml (`examples/jsonrpc-agent/tests/fixtures/subagent/subagent-dsh-sdk/`) where the child is a REAL second harness runtime with its own cordis.yml; asserts the parent tool result and the child's own persisted transcript both carry the parent session's cwd. The child launch resolves through `resolveExampleLaunch`, so src/lib modes both hold.
-- **Keyless snapshot** — `examples/jsonrpc-agent/tests/sdk.snapshot.ts` is the jsonrpc example's first snapshot suite: the real `dsh-jsonrpc-agent` runtime driven through the real `dsh-sdk-client`, replaying recorded fixtures via `llm-replay` behind the new `cordis.snapshot.yml` overlay (passed explicitly through `DSH_CORDIS_CONFIG`; the jsonrpc bin performs no snapshot config swap of its own). Three scenarios — text turn, bash tool, spawn subagent — each pinning the normalized notification stream, the SDK turn result, and the persisted parent+child logs. This also closes the protocol-tier gap the single-exe note's Python-side snapshot left on the vitest side.
+- **Keyless Loader composition** — `subagent-dsh-sdk/tests/loader-composition.e2e.ts` boots a test-only cordis.yml (`examples/python-sdk-agent/tests/fixtures/subagent/subagent-dsh-sdk/`) where the child is a real second `dsh --profile sdk` runtime with its own isolated home and ordered patch; asserts the parent tool result and the child's own persisted transcript both carry the parent session's cwd.

-`mux()` subscribes `ctx.jobs.onJobsChanged` and pushes `session/jobs`; the subscription baseline rides next to the existing `session/subscribed` control frames, so a reconnecting client is current before it renders.

Every physical reconnect opens a new generation, so the client replaces its process-local mirror before applying further changes.
 
 Four rules the carrier keeps:
 
-- **Never resume.** A change push reads `jobs.list(owner)` with the exact `Agent` the listener supplied, which stays correct even while that owner's scope is tearing down and a lookup by id would already miss. The baseline instead reads `ctx.jobs.list(ctx.agents.get(session.id))` — the non-resuming registry read, where a session with no live Agent correctly yields only the unowned tasks. Neither path touches the [`api-remotes` Agent resolver](../../../../packages/api/remotes/src/agent-lookup.ts), which resumes a cold session as a side effect of lookup; listing must never revive a session the user merely scrolled past.
-- **Fan out unowned changes.** An `undefined` owner pushes a fresh snapshot to every subscribed session, because unowned tasks are visible to every caller.
-- **Stay optional.** The carrier reads `ctx.get('jobs')`. A composition without the registry emits no frames, and the client renders no entry point — the posture `sessionProjections` already has in this file.
-- **Say nothing about nothing.** The baseline is pushed only for sessions whose list is non-empty, and an absent key on the client means an empty list. A change that empties a list still pushes `[]`, because that one transition is the only thing the client cannot infer from absence.

 It lives on the list mirror rather than on `Session` for three reasons: the header action already reads list state through `useSessions`, nothing needs the pre-instantiation buffering `session/queue` requires (no composer behavior depends on tasks), and a later sidebar indicator gets the data without opening a second channel.
 
-Two clears keep it honest. On re-subscribe the manager drops the session's mirror — the rule `session/queue` already follows, because a fresh baseline is arriving and this generation sends none for an empty set, so a retained list would survive as a phantom. On `host/session-removed` it drops the mirror again: owner disposal already removed the records registry-side, but that lands on the mux stream while the removal frame rides the host stream, so the two have no relative order.

This is what the subagent catalog does, and the cost is visible in [`SessionManager`](../../../../packages/client/runtime/src/client/sessions/manager.ts): `catalogInflight` for single-flight, `catalogStale` for a trailing re-pull when a membership frame lands mid-request, `updateCatalogActivity` patching loaded rows in place *and* writing into the in-flight request so a response older than the frame gets overwritten, `parentAvailableOverride` replaying a stale `false`, and a reconnect path re-pulling every open catalog. That apparatus exists because the catalog's authority is split — durable lineage from a projection, liveness sampled at response time — and tasks have no durable half to justify inheriting it. It also fails specifically at the moment the output phase cares about: a task settles, its output stream closes immediately, but status only arrives after debounce plus round-trip, so the UI shows a running task with a dead stream for that window.

-- **绝不 resume。** 变更推送用监听器给出的确切 `Agent` 调 `jobs.list(owner)`，即使该 owner 的 scope 正在拆除、按 id 查找已经查不到，它依然正确。baseline 则读 `ctx.jobs.list(ctx.agents.get(session.id))`——不触发 resume 的注册表读法，没有活体 Agent 的会话正确地只得到无主任务。两条路径都不碰 [`api-remotes` 的 Agent 解析器](../../../../packages/api/remotes/src/agent-lookup.ts)，那个解析器会把查询变成复活冷会话的副作用；列个任务不该让用户随手划过的会话活过来。
-- **无主变更要扇出。** `owner` 为 `undefined` 时向每一个已订阅会话推一份新快照，因为无主任务对所有调用方可见。
-- **保持可选。** 载体读 `ctx.get('jobs')`。没有挂注册表的组合不发任何帧，客户端也就不渲染入口——`sessionProjections` 在这个文件里已经是这个姿态。
-- **没有就不说。** baseline 只为列表非空的会话推送，客户端上键缺失即表示空列表。把列表清空的那次变更仍然推 `[]`，因为这一个转换是客户端唯一无法从「缺失」推断出来的东西。

+One drift gate per pi-ai compat type — keyed `Record<keyof OpenAICompletionsCompat | …, CompatDisposition>` — classifies every upstream field as `offer` or `withhold`.

 `PiAiCompatProfile` stays an explicit interface with per-field JSDoc — it is what a configuration surface renders and what `docs/config-catalog.md` pastes — and a type-level `AssertNever` over the symmetric difference proves it names exactly the offered set. The schemastery schema is declared `z<PiAiCompatProfile>`, and `exactOptionalPropertyTypes` is what makes that annotation load-bearing in both directions, so the four faces lock together: an upstream field added, a gate entry missing, an interface field forgotten, or a schema key omitted each fails compilation. Field *types* are derived from upstream rather than restated, and a second proof pins the profile assignable to the upstream compat types, so a widened value union cannot silently narrow what configuration accepts — the cast to `ModelCompat` at materialization would otherwise hide it.
 
-Protocol applicability is per field, and grouping follows the compat *type* rather than the protocol name: pi-ai gives `openai-responses`, `azure-openai-responses`, and `openai-codex-responses` one `OpenAIResponsesCompat`, so a switch settable on one is settable on all three. Keying by protocol name alone refused two shipped catalog routes the fields their own models declare. The protocol set is derived from `Model.compat`'s own conditional, so a release that gives a further protocol a compat type fails the gate list by name. A model-level switch its protocol does not take fails resolution naming what that protocol does offer; a route-level one lands on the models that read it and skips the rest, and is refused only when no model on the route could read it. `chatTemplateKwargs` is offered, which is what makes the two `chat-template` thinking formats nameable; nothing cross-checks that pairing, because the format in force may come from the catalog entry or from pi-ai's detection, neither of which resolution can read.

-Three kinds of `compat` key are refused where they are written rather than dropped: one no protocol declares, one a gate withholds, and one written with no value. The check runs over every key before any protocol resolves, so a misspelling fails even on a route whose models never reach the protocol that would have taken it. It reads raw keys deliberately: a withheld or undeclared name is absent from the schema, so schemastery cannot have materialized it and a person wrote it. The valueless case is the one that has to fail rather than be ignored — schemastery passes a YAML bare key through as null, and carrying it forward writes null over the installed catalog's value, leaving pi-ai's `??` reaching for its baseURL detection with the catalog layer skipped entirely. Fields carrying a value are then filtered separately, because schemastery materializes an absent dict as `{}` and `chatTemplateKwargs` is present on every parsed profile whether or not anyone wrote one.

 - Unknown compat keys join every other configuration error's failure model. The improvement over the previous silent drop is bounded by the settings seam: an external file edit still keeps its last good value and warns, so the operator's signal is a restart rather than the write.
 - **Deferred, not closed:** a route that repoints `api` and configures no compat at all keeps the installed entry's `compat` through the model literal's `...base` spread, in the *other* protocol's shape. Fields several compat types share (`supportsLongCacheRetention`, `sendSessionAffinityHeaders`) therefore cross protocols. It predates this surface — the early return it rides existed before — and is left for its own change.
 - **Deferred, not closed:** `publish()` reports a rejected stored section only through `ctx.logger.warn`, with no user-visible channel. It affects every settings namespace and is owned by `dsh-settings`.

+# Agent Note: Fire-and-forget webhook Sessions
+
+Status: implemented
+
+English | [中文](2026-08-22-fire-and-forget-webhook-sessions.zh.md)
+
+## Problem
+
+External repository events need to start ordinary DSH work without making every provider adapter understand Agent presets, Workspace attachment, titles, permissions, and callback teardown. GitHub pull requests becoming ready for review are the first use: a signed event may create a review Session that users can browse under the repository Workspace.
+
+Turning this into a durable automation engine would introduce a second lifecycle beside Sessions: delivery records, execution states, retry and deduplication policy, crash recovery, and an answer to whether HTTP acceptance, prompt admission, Agent idle, or model output means completion. The requested capability needs none of those meanings.
+
+## Decision
+
+`@deepseek-ai/dsh-webhook` owns a two-operation Host runtime: rules register through `register()`, and authenticated provider adapters call `dispatch()`. Each matching callback runs independently as arbitrary trusted code and returns `null` or one Workspace-backed Session request. Dispatch returns before callbacks settle, while effect disposal aborts and drains only the calls it owns.
+
+The runtime stores no provider delivery or execution record. It does not retry, deduplicate, resume callback work, observe Agent status, or collect a result. A repeated delivery may create another Session. `WebhookDeliveryId` remains available to a rule that deliberately implements idempotency through its own state.
+
+## Provider adapters
+
+Authentication belongs to provider adapters. `@deepseek-ai/dsh-webhook-github` registers one exact route on an injected WebServer, bounds the untouched UTF-8 body, resolves its secret reference per request, verifies `X-Hub-Signature-256` before parsing, and passes a signed lossless-JSON object to the runtime. `202` means only verified in-memory dispatch; it precedes rule matching, external calls, and Session creation.
+
+The normal Web composition keeps its UI/API WebServer separate. The GitHub example mounts another WebServer and its adapter in a group that isolates only `webServer`, so a reverse proxy can expose the webhook port without exposing `/api`, WebSockets, or frontend files.
+
+Patch loading anchors relative plugin names in inserted rows to the patch file. The same `./github-ready-review-rule.mjs` entry therefore works from a development `--patch` overlay and from a permanent profile patch without changing the rule into a package.
+
+## Session creation
+
+A rule result names a local Workspace path, title, text prompt, agent preset, permission preset, and optional explicit provider/model route with an output cap. Without that route, the runtime snapshots the complete live default, including reasoning effort, until the first request records its durable header. It validates presets before mutation, resolves or creates the canonical Workspace, creates the Agent with that path as Session cwd, mounts the preset before publication, and attaches the Session before admitting the prompt.
+
+The initial follow-up is an ordinary durable user-role message with webhook provider, source, delivery, and rule provenance. Its inbox insertion is the webhook operation's last boundary. Ordinary Session persistence and Agent lifecycle own later work; the runtime neither flushes specially nor waits for a turn.
+
+## Alternatives considered
+
+**Persist deliveries and execution states.** Rejected because `pending`, `admitted`, `running`, and `settled` require retry, deduplication, crash, and completion semantics that the current capability does not consume.
+
+**Acknowledge GitHub after Session creation.** Rejected because arbitrary rules may call external systems and exceed the provider's HTTP window; a valid delivery should not couple transport availability to later rule work.
+
+**Register the route on the main WebServer.** Rejected because operators need to expose webhook ingress without also exposing the browser API. An isolated second instance reuses the existing HTTP module without creating another server implementation.
+
+**Restrict rules to a declarative predicate language.** Rejected because programmatic rules explicitly need arbitrary external calls. Trusted Cordis plugins already provide the required authority and lifecycle.
+
+**Let each adapter create Sessions directly.** Rejected because Workspace, preset, permission, title, rollback, and provenance logic would spread across provider packages.
+
+## Verification
+
+Package tests pin independent callback execution, fire-and-forget HTTP timing, cancellation and quiescent disposal, request validation, Workspace attachment before prompt admission, rollback, GitHub HMAC and body limits, credential rotation, and exact Loader composition. The assembled Web example sends a signed ready-for-review delivery to an isolated second listener and records the resulting ordinary Workspace conversation.
+
+A real-API e2e test starts the built `dsh web` CLI with the webhook overlay and isolated listener, synthesizes only the signed inbound GitHub delivery, observes Workspace attachment and durable provenance through the public Web API, and waits for the real DeepSeek response. No DSH service, model adapter, or provider call is replaced by a test double.
+
+Source audits keep execution records, retry timers, dedupe maps, completion events, and Agent-status listeners absent.
+
+## Consequences
+
+- Provider adapters stay small and provider-specific while Session creation has one owner.
+- Users receive ordinary titled Sessions under Web Workspaces rather than a second automation UI.
+- HTTP success intentionally says nothing about downstream matching or Agent success.
+- Crashes and repeated deliveries retain simple at-most-process-lifetime semantics; deployments needing durable automation must add a separately designed subsystem rather than reinterpret this runtime.

+# Agent Note: Fire-and-forget webhook Session
+
+Status: implemented
+
+[English](2026-08-22-fire-and-forget-webhook-sessions.md) | 中文
+
+## Problem
+
+外部仓库事件需要启动普通 DSH 工作，同时不能让每个提供方适配器都理解 Agent preset、Workspace 附加、标题、权限与回调 teardown。GitHub pull request 变为 ready for review 是第一个用途：签名事件可以创建一个评审 Session，用户能在仓库 Workspace 下浏览它。
+
+如果把它变成持久自动化引擎，就会在 Session 旁引入第二套生命周期：交付记录、执行状态、重试与去重策略、崩溃恢复，以及 HTTP 接受、提示词接纳、Agent idle 或模型输出中究竟哪个表示完成。所请求能力不需要其中任何含义。
+
+## Decision
+
+`@deepseek-ai/dsh-webhook` 拥有只有两个操作的 Host runtime：规则通过 `register()` 注册，已验证身份的提供方适配器调用 `dispatch()`。每个匹配回调都作为任意受信任代码独立运行，并返回 `null` 或一个基于 Workspace 的 Session 请求。dispatch 会在回调结算前返回，而 effect disposer 只中止并排空自己拥有的调用。
+
+runtime 不存储提供方交付或执行记录。它不重试、不去重、不恢复回调工作、不观察 Agent 状态，也不收集结果。重复交付可能创建另一个 Session。`WebhookDeliveryId` 仍可供有意通过自有状态实现幂等性的规则使用。
+
+## Provider adapters
+
+身份验证属于提供方适配器。`@deepseek-ai/dsh-webhook-github` 会在注入的 WebServer 上注册一条精确路由，限制未改动的 UTF-8 body，为每次请求解析密钥引用，在解析前验证 `X-Hub-Signature-256`，并把签名无损 JSON 对象交给 runtime。`202` 只表示已验证的内存分发；它先于规则匹配、外部调用和 Session 创建。
+
+普通 Web 组合保持其 UI/API WebServer 独立。GitHub 示例会把另一个 WebServer 及其适配器挂载到只隔离 `webServer` 的 group 中，因此反向代理可以暴露 webhook 端口，而不暴露 `/api`、WebSocket 或前端文件。
+
+Patch 加载会把插入行中的相对插件名锚定到 patch 文件。因而同一个 `./github-ready-review-rule.mjs` 条目既可用于开发环境的 `--patch` overlay，也可用于永久 profile patch，而无需把规则改成软件包。
+
+## Session creation
+
+规则结果会指定本地 Workspace 路径、标题、文本提示词、agent preset、permission preset，以及可选的明确提供方／模型路由与输出上限。没有明确路由时，runtime 会快照包含推理强度的完整实时默认选择，直到首个请求记录其持久 header。runtime 会在变更状态前验证 preset，解析或创建规范 Workspace，以该路径作为 Session cwd 创建 Agent，在发布前挂载 preset，并在接纳提示词前附加 Session。
+
+初始 follow-up 是普通持久 user-role 消息，并携带 webhook 提供方、来源、交付和规则来源信息。它的 inbox 插入是 webhook 操作的最后边界。之后的工作由普通 Session persistence 与 Agent 生命周期拥有；runtime 既不执行特殊 flush，也不等待轮次。
+
+## Alternatives considered
+
+**持久化交付与执行状态。** 否决，因为 `pending`、`admitted`、`running` 与 `settled` 需要当前能力没有消费方的重试、去重、崩溃和完成语义。
+
+**在 Session 创建后再向 GitHub 确认。** 否决，因为任意规则可能调用外部系统并超过提供方 HTTP 时间窗；有效交付不应把传输可用性与后续规则工作耦合。
+
+**在主 WebServer 上注册路由。** 否决，因为操作者需要暴露 webhook 入口而不同时暴露浏览器 API。隔离的第二个实例会复用现有 HTTP 模块，而不会创建另一套服务器实现。
+
+**把规则限制为声明式谓词语言。** 否决，因为程序化规则明确需要任意外部调用。受信任 Cordis 插件已经提供所需权限与生命周期。
+
+**让每个适配器直接创建 Session。** 否决，因为 Workspace、preset、权限、标题、rollback 与来源信息逻辑会散布到各提供方包。
+
+## Verification
+
+包级测试固定独立回调执行、fire-and-forget HTTP 时序、取消与静止态释放、请求验证、提示词接纳前的 Workspace 附加、rollback、GitHub HMAC 与 body 限制、凭据轮换和精确 Loader 组合。组装 Web 示例会向隔离的第二监听器发送签名 ready-for-review 交付，并记录所得普通 Workspace 对话。
+
+真实 API e2e 测试会通过带 webhook overlay 与隔离监听器的构建产物启动 `dsh web` CLI（命令行界面），只合成带签名的入站 GitHub 交付，通过公开 Web API 观察 Workspace 附加与持久来源信息，并等待真实 DeepSeek 响应。测试不会用 test double 替换任何 DSH 服务、模型适配器或提供方调用。
+
+源码审计会保持执行记录、重试 timer、去重 map、完成事件与 Agent 状态监听器不存在。
+
+## Consequences
+
+- 提供方适配器保持小而且只含提供方逻辑，Session 创建只有一个 owner。
+- 用户在 Web Workspace 下获得普通带标题 Session，而不是第二套自动化 UI。
+- HTTP 成功刻意不说明下游匹配或 Agent 成功。
+- 崩溃与重复交付保持简单的进程生命周期内语义；需要持久自动化的部署必须增加单独设计的子系统，而不是重新解释此 runtime。
