 Ship **two** adapters against the one contract from the start, deliberately built on different internals:

- `dsh-llm-deepseek` — hand-rolled `fetch` + SSE parsing against the DeepSeek API.
+- `dsh-llm-deepseek` — direct `fetch` + in-repo translation against the DeepSeek API; SSE framing is delegated to `eventsource-parser` ([the SSE-parser swap](../simplification/2026-07-26-eventsource-parser-for-deepseek-sse.md)). The twin identity is owning the fetch/translate internals rather than delegating to a full provider SDK, not hand-rolling transport plumbing.
 - `dsh-llm-pi-ai` — the same endpoint through the `@earendil-works/pi-ai` library (its own event vocabulary).

-The rule they enforce: **anything the StreamChunk vocabulary cannot express for BOTH implementations is a core-vocabulary bug**, caught immediately rather than at the next provider. The pair pinned down conventions now documented on `StreamChunk` in `dsh-llm/src/types.ts`: usage emitted before finish, nothing after finish, tool-call `arguments` as raw JSON strings end-to-end, and the two sanctioned error paths (throw from `stream()` *or* end with `finish {kind:'error'|'aborted'}`) that a consumer must handle on both sides — a divergence the library-backed adapter surfaced that a single hand-rolled adapter would have hidden.

+# Agent Note: Adapter-owned reasoning effort capabilities
+
+Status: implemented

+
+## Problem
+
+Reasoning strength was adapter configuration only, so a conversation could not discover or change the selected model's supported levels between requests. Promoting one adapter's level union into `dsh-llm` would make every provider and model adopt names it may not support, while a provider-specific options bag would make the loop unable to validate or durably reconstruct the effective request.
+
+## Decision
+
+`dsh-llm` represents a reasoning effort as the opaque branded `ReasoningEffortId`. One adapter-owned `resolveModel(provider, model, signal?)` query returns `LlmResolvedModelInfo`: exact model identity plus optional context and reasoning metadata. `LlmService.resolveModelInfo()` validates and detaches that aggregate. When present, `reasoning.efforts` is a non-empty ordered list of ids with display metadata and may name one configured default. The core requires an explicit or configured effort to appear exactly in that list and never clamps or aliases a value.
+
+`LlmCallConfig` and `GenerateOptions` carry the optional effort. The agent loop prepares the post-`agent/request` config under the active turn signal before writing `request/header`, so defaults and dynamic changes are model-visible only after becoming durable facts. The prepared call retains the exact adapter registration across asynchronous exact-model resolution, durable header logging, and dispatch; direct `LlmService.stream()` calls likewise capture their final registration before awaiting resolution. A route with no registered adapter retains its proposed config so an `llm/stream` middleware can own and short-circuit it; terminal dispatch still rejects an unhandled route. A resumed loop retains the logged effort only when its initial provider/model route is unchanged; a route change discards the previous model's opaque id.
+
+The native DeepSeek adapter advertises `off`, `high`, and `max` when deployment policy permits thinking, and defaults to the configured effort or `high`. Its adapter-owned `off` maps to `thinking.type: disabled` with no `reasoning_effort`; `high` and `max` enable thinking and carry their official wire effort. A `thinking: disabled` deployment publishes only `off` and rejects attempts to enable thinking before provider I/O. The pi-ai adapter publishes each exact model's `getSupportedThinkingLevels()` result unchanged, including `off`, preserves an absent profile default as a provider default, and leaves provider wire-value mapping inside pi-ai. Its common stream options represent `off` by omitting `reasoning`, as required by pi-ai's own API.
+
+## Alternatives considered
+
+**Define the pi-ai `ThinkingLevel` union in core.** Rejected because current pi-ai canonical names are an adapter implementation detail; a future provider can expose a different identifier without requiring a core release.
+
+**Carry an untyped provider options object.** Rejected because the loop could neither validate a selected value nor put a stable provider-neutral fact in the request header.
+
+**Clamp unsupported levels.** Rejected because a silent substitution makes the user's selected control differ from the logged request intent and hides stale deployment configuration.
+
+**Normalize every adapter to a core-owned level list or remove `off`.** Rejected because the selectable vocabulary belongs to the exact model capability. A client can render an adapter's `off` option without requiring every adapter to expose it.
+
+## Consequences
+
+Clients can query one exact route once and render its identity, context capacity, and adapter-owned reasoning choices without knowing a global enum or synthesizing `off`. Adapter configuration remains the deployment-default and policy owner, while `agent/request` can replace the effective effort on each step within that policy. Invalid exact identity, context, or reasoning metadata fails with `INVALID_MODEL_INFO`, `INVALID_MODEL_CONTEXT`, or `INVALID_MODEL_REASONING`; unsupported explicit or configured values fail with `UNSUPPORTED_REASONING_EFFORT` before provider I/O.
+
+The aggregate exact-model query is asynchronous and may fail for adapters backed by authoritative catalogs. Its optional signal is the caller's cancellation boundary; an asynchronous adapter must settle promptly after abort so loop disposal can reach quiescence. Keyless service, adapter, loop, session, and request-header tests pin validation, defaulting, dynamic changes, logging, resume behavior, HMR registration ownership, and cancellation; runnable snapshots pin the resolved effort in real assembled request headers, while key-gated adapter tests exercise provider serialization.

+# Agent Note：适配器持有的推理强度能力
+
+Status: implemented
+
+[English](2026-07-24-adapter-owned-reasoning-effort-capabilities.md) | 中文
+
+## 问题
+
+推理强度过去只能在适配器中配置，因此对话无法在多次请求之间发现或更改所选模型支持的等级。若将某个适配器的等级联合类型提升到 `dsh-llm`，所有提供方和模型都必须采用一套自身可能并不支持的名称；若改用提供方特有的 options 对象，主循环又无法校验最终生效的请求，也无法通过持久化记录准确重建该请求。
+
+## 决策
+
+`dsh-llm` 使用不透明的品牌类型 `ReasoningEffortId` 表示推理强度。由适配器持有的单次 `resolveModel(provider, model, signal?)` 查询返回 `LlmResolvedModelInfo`，其中包含确切模型身份以及可选的上下文和推理元数据。`LlmService.resolveModelInfo()` 会校验该聚合结果并返回分离值。`reasoning.efforts` 存在时，是包含展示元数据的非空有序 ID 列表，并可指定一个由配置确定的默认值。核心要求显式指定或配置指定的推理强度与列表中的某个 ID 完全一致，且绝不自动调整或为值提供别名。
+
+`LlmCallConfig` 和 `GenerateOptions` 携带可选的推理强度。agent loop（智能体循环）在活跃轮次信号的控制下准备 `agent/request` 处理完成后的配置，再写入 `request/header`，因此默认值和动态变更只有成为持久化事实后才对模型可见。准备完成的调用在异步确切模型解析、请求头持久记录和分派全程保留同一项确切的适配器注册；直接调用 `LlmService.stream()` 时，也会在等待解析前捕获最终的适配器注册。没有已注册适配器的路由会保留原定配置，使 `llm/stream` 中间件可以接管并短路该请求；若仍未得到处理，最终分发会拒绝该路由。恢复后的主循环仅在初始提供方/模型路由未变时保留日志中记录的推理强度；如果路由发生变化，则丢弃上一模型的不透明 ID。
+
+当部署策略允许思考时，原生 DeepSeek 适配器声明 `off`、`high` 和 `max`，默认使用配置指定的推理强度，若未配置则使用 `high`。由适配器持有的 `off` 映射为 `thinking.type: disabled`，且不带 `reasoning_effort`；`high` 和 `max` 会启用思考并携带各自的官方协议强度值。配置为 `thinking: disabled` 的部署仅声明 `off`，并会在提供方 I/O 前拒绝启用思考的尝试。pi-ai 适配器原样发布每个确切模型的 `getSupportedThinkingLevels()` 结果，其中包括 `off`；profile 未指定默认值时保留提供方默认行为，并将提供方协议值的映射留在 pi-ai 内部。按照 pi-ai 自身 API 的要求，其通用流选项通过省略 `reasoning` 来表示 `off`。
+
+## 备选方案
+
+**在核心中定义 pi-ai 的 `ThinkingLevel` 联合类型。** 不予采纳：pi-ai 当前的规范名称属于适配器实现细节；未来的提供方可以暴露不同的标识符，而无需为此发布新的核心版本。
+
+**携带无类型约束的提供方 options 对象。** 不予采纳：主循环既无法校验选定值，也无法在请求头中写入稳定且与提供方无关的事实。
+
+**自动调整不支持的等级。** 不予采纳：静默替换会导致用户选定的控制项与日志记录的请求意图不一致，还会掩盖陈旧的部署配置。
+
+**将每个适配器规范化为核心持有的等级列表，或移除 `off`。** 不予采纳：可选值集合属于确切模型的能力。客户端可以渲染某个适配器的 `off` 选项，而无需要求所有适配器都暴露该选项。
+
+## 影响
+
+客户端只需查询一次确切路由，即可渲染其身份、上下文容量和由适配器持有的推理选项，而无需了解全局枚举或自行合成 `off`。适配器配置仍是部署默认值和策略的归属方，`agent/request` 则可以在该策略范围内为每个步骤替换实际生效的推理强度。确切身份、上下文或推理元数据无效时，分别抛出 `INVALID_MODEL_INFO`、`INVALID_MODEL_CONTEXT` 或 `INVALID_MODEL_REASONING`；显式指定或配置指定的值不受支持时，会在提供方 I/O 前抛出 `UNSUPPORTED_REASONING_EFFORT`。

+# Agent Note: Web client Agent-scope parity model and the provisioning channel (agents/scope / blank reuse / provide)
+
+Status: implemented
+
+English | [中文](2026-07-25-web-client-session-scope-and-provide-channel.zh.md)
+
+> Scope: the client Agent scope (actx) and targeted events, the client/host materialization parity model, the blank-session bit and reuse (`connectWorkspace`), the per-session provisioning channel (`sessions.provide`), the read-only queue mirror (`session/queued`), and the host wire smalls that carry these capabilities (the summary `blank` column, the `host/session-added` frame field, and the `host/commands-changed` frame). The input state machine and the slash pipeline live in the [input machine note](2026-07-25-web-input-machine-and-slash-pipeline.md); the command business surfaces live in the [command surfaces note](2026-07-25-web-command-surfaces-and-assembly.md).
+
+## Problem
+
+The web client had a single global session surface: slots all rendered from the root context, so plugins had no notion of "which agent/session is current"; the draft's true copy was buried inside the Session object, leaving any plugin that wanted to participate in input with nowhere to hook in. To support a command/input system, the platform layer first had to answer:
+
+- Who owns session interaction state (menus, popups, drafts, in-flight requests), and how two sessions are structurally isolated;
+- What a "new session" is before the host entity exists — whether the client must forge an independent life for it;
+- How session-scope components fetch their own session data, instead of props passed down layer by layer;
+- What a user-abandoned new session leaves behind on the host side, and who collects it.
+
+Hard constraints: the host is the single source of truth; every registration goes through a `ctx.effect` disposer; the scope mechanism matches the host's Agent scope architecture; model-visible ⟺ already in the session log.
+
+## Decision
+
+### The parity model: client and host share one root state axis
+
+Host-side `session.create(workspaceId)` produces Session + Agent + cwd in one piece (an atomic bundle, never split); the client side is the mirror of that birth — the instant a session row enters the list mirror, the client mints its Agent scope (actx + provide + the full input surface mounted):
+
+- Session identity is the host's true form from birth: the sessionId arrives via the `session.create` response / the `host/session-added` frame, and every client-side address (the scope tag, slot store keys, RPC addressing) uses that same id.
+- The materialization moment = the instant the user picks a Workspace (cwd settled): the client calls `session.create({workspaceId})` on the spot and receives the complete entity.
+- "New Session with no workspace picked" is a **pure view state** (a navigation position) corresponding to no session/scope entity; until the pick, the composer is locked whole (no slash, no plain text).
+- A "blank session" is just an ordinary materialized session whose log is still empty; to every Agent-scope plugin on the host (goal/plan/skill/…) it is indistinguishable from any session, so slash/plan are all naturally live.
+
+### Agent scope: the actx is the sole session carrier in the client-side cordis world
+
+The runtime's `agents/scope.ts` matches the host's `dsh-scope` at the mechanism layer (fiber + tag + filter; no value import: the host package carries the scoped-events `Events` merge, which would collide with the Context merge inside the client program):
+
+- `createScope(ctx, key)`: a no-op plugin fiber plus `extend({[kScope]: key, [Context.filter]: …})` — the filter lives directly on the actx: untagged listeners receive globally, tagged ones receive only their own scope.
+- Dispatch is the cordis primitives with thisArg = the actx itself: `actx.bail(actx, event, req)` / `actx.emit(actx, event, payload)`.
+- `Session.bindScope(actx)`: paired exactly once when resolve mints the scope (rebinding throws; dropScope unbinds), mirroring the host's `Agent.loopCtx` — the Session uses it to dispatch its own scoped events. The reverse actx→Session direction is one hop through `sessions.sessionOf(actx)` (mirroring host plugins' `agent.session` usage).
+
+Three deliberate divergences from the host dsh-scope:
+
+- The filter lives on the actx itself rather than a separate carrier: the host wrapper layer guards the business Agent subject against drifting from the scope key (host events inject the Agent itself as the first argument), while client event payloads carry only an id — there is no subject to protect.
+- Keys compare by branded `SessionId` value rather than object identity: on the host, agent.id === session id (1:1 on the same axis), agent identity directly reuses the `SessionId` brand, and a client scope's identity is its wire id.
+- The client scope is an **Agent identity** scope, not a live-object scope: during a cold session the host Agent object is already disposed while the client actx stays alive (in view) — the identity axis is in strict parity while object hot/cold is deliberately unsynchronized.
+
+id→ctx handoff is allowed in only three kinds of places (business providers never hand off):
+
+- Slot inject factories: the ctx never enters the render layer; the identity the slot framework hands a component is the sessionId, exchanged back into objects/controllers through service maps.
+- Root coordination services self-addressing: from a projection's sessionId back to the actx via `sessions.scope(id)`.
+- Root untagged listeners: looking up their own store by the payload's sessionId.
+
+### Scope lifecycle: anchored to the list mirror — birth is entering view, death is prune
+
+Session instances share the scope's lifecycle; liveness eligibility = host-listed (one criterion, shared by mint and prune):
+
+- Birth = a session row entering client view (the list baseline pull / the local `create()` echo / the `host/session-added` frame); a lazy first resolve mints the scope (resolution is a pure function, render-safe).
+- One prune tears down three things together: the Session instance, the scope fiber (cascading through every consumer hung on the actx), and the session-keyed slot store. The staged session (= `list.current`) is the exception: removed while still on stage, it keeps a frozen read-only view, torn down only once the stage moves away.
+- Reopening = lazily rebuilding the instance + `open()` pulling history (the host session log is the durable truth).
+- Remaining TODO: approval/question frames never enter history and cannot be recovered across a prune (the manager-level pendingBuffers cover only the never-instantiated window).
+
+### The blank bit: the empty session's visible projection, conversion, and reuse
+
+A session "materialized but with no first prompt" is governed by the summary-derived bit `blank` (a derived column, not a header field; SessionHeader stays immutable):
+
+- The host criterion: `session.events.length === 0` (zero log events = no user message yet). A live session reads `summarize()` straight from memory; a cold session is always `false` — the lazy-create contract guarantees a never-appended session never enters `persistence.list()` at all (both the JSONL and SQLite backends are verified truly lazy), so blank never touches disk.
+- The wire carries it in two places: the required `SessionSummary.blank` column, and the required `blank` field on the `host/session-added` frame (always true at creation, letting other tabs enter the same blank-session state into their mirrors).
+- The client mirror only lowers, never raises (monotonic), flipped from three sources, all reusing existing wire signals:
+  - The sender's own tab: the **successful response** to the first `prompt()` flips false (acceptance proves the user/message is already in the host log — this flip is confirmation, not optimism; `onEngaged` synchronously updates the list mirror, converting the current `New Session` row in place to an ordinary title, adding no list row). A rejected first prompt keeps the session blank: aligned with host authority, still shown as `New Session`, keeping its connectWorkspace reuse eligibility.
+  - Other tabs: the `host/session-status (running:true)` frame flips it — a blank session never runs, so the first running necessarily means no longer blank;
+  - Reconnect alignment: `session.list`'s summary.blank is authoritative, so a tab that missed frames aligns naturally on its next pull; a stale blank:true can never mark a converted session back to blank.
+- List discipline: the store retains every row; the Workspace browser's grouping, flat view, search, and counts share one visible projection — every non-blank session shows, while blank sessions show only the one with `session.id === sessions.current`, its title forced to `New Session`. After a Workspace switch, the old blank entity stays in the mirror but is hidden from the list while the target Workspace's current blank shows; the user-visible surface therefore holds at most one blank row globally.
+- The residue ledger takes zero GC: after a refresh, blank sessions come back with the bit intact and are reused on the next same-workspace connect, so the ordinary single-tab path keeps at most one per workspace; after a host restart, blanks leave no disk trace and simply evaporate; the extra empty shells from multi-tab races only become non-current hidden rows, digested by later reuse, with no coordination.
+
+### connectWorkspace: the sole entry point of New Session
+
+`workspaces.connectWorkspace(workspaceId): Promise<SessionId>` (owned by WorkspacesService — it holds both the workspace canonical path and the sessions reference):
+
+- The reuse arm: the list mirror is searched for `blank && cwd == workspace.path` (direct equality on the host realpath canonical form); a hit returns that id directly, creating nothing.
+- The create arm: on a miss, `session.create({workspaceId})` returns the new id.
+- An unknown workspaceId fails loud (never silently creating somewhere else).
+- The resolution guarantee (one contract for both arms): when the promise resolves, the returned id is already in the list store and `sessions.binding(id)` resolves synchronously — `SessionsService.create` projects the list synchronously after RPC success before resolving, so a draft mover can write text into the new scope's machine before open, without waiting for a notifier flush.
+- The caller takes the id and does its own `sessions.open`; sending the first prompt is an ordinary `session.prompt` — the session already exists, a failure is an ordinary prompt failure, the draft text is still in the machine, and a retry is simply sending again.
+- The global New Session button defaults to `recentWorkspaceId`: first comparing each Workspace's newest Session `updatedAt`, falling back to the Workspace `createdAt` when it has no Sessions, and keeping host order on ties; only with no Workspace at all does it `sessions.clear()` into the no-session view. Create actions inside a Workspace group still hit that Workspace explicitly.
+- At startup the runtime subscribes to the first complete baseline: a successfully restored current session is kept in place; otherwise it automatically calls `connectWorkspace(recentWorkspaceId)` and opens the returned blank session. The policy settles only once; a later user-initiated clear is never overridden by auto-selection again, and a connect failure waits for the next baseline projection to retry.
+- Re-picking the Workspace in the blank Hero also goes through `connectWorkspace`; when the target id differs from the current one, the current input machine's non-empty draft moves to the target scope first, then `sessions.open(nextId)`. The old blank entity is not deleted — it merely leaves the list by no longer being current.
+
+### Per-session provisioning: the `sessions.provide` standard-kit channel
+
+The sole provisioning path by which session slot components fetch their own session data. Plugins declare a fixed key map through the static descriptor `sessions.provide({hooks, props, resolve})` (a duplicate key throws at registration); `resolve(binding)` materializes values for a specific session and tears them down with the scope. Web-react's `standardKit` single loop binds the hooks compartment into `use<Name>` selector hooks (`observableHook`→uSES, anti-tearing) and passes the props compartment through as-is.
+
+Slot scope is the closed set `root | session-maybe | session`:
+
+- `root` receives only the global standard kit, with no session identity or provisioning.
+- `session-maybe` follows the current session, but the component instance does not change key when the id appears, disappears, or changes; with no session, `sessionId`, the results of `useSession`/`useInput`, and `inputActions` may all be absent. The unkeyed root `SessionMaybeProvider` drives these updates, while `SessionMaybeProvideInfo` uses the static key map to retain the complete hook/prop shape even with no session.
+- `session` guarantees that `sessionId`, every hook source, and every prop exist; each strict entry's error boundary is keyed by `sessionId`, so switching sessions recreates that entry and its session store.
+
+`conversation` is the resident `session-maybe` shell: `ConversationRoot`, HeroShell, the Workspace picker, the composer stack, and the overlay chain's fallback frame retain their React instances across the no-session → blank-session switch; `conversation.session` carries only the strict-session header/view, while the composer and every input slot also stay strict `session`. With no session, the composer stack places the presentation-only `DisabledInputBar` directly; once a session appears, the input body is swapped for the strictly bound InputBar; the textarea may be rebuilt, while the Hero and the layout skeleton are not. The blank → engaging/active transition stays inside the same strict-session subtree, and the InputBar is never rebuilt on a phase flip.
+
+- The runtime's first built-in entry: the `'session'` hook — `useSession` itself rides the same mechanism, no special-casing.
+- Concurrent discipline: the render plane reads only from the hooks compartment (uSES consistency guarantee); props-compartment callbacks are used only in event-handler space; descriptor resolution is render-safe (idempotent caching, with prune reaping residue from abandoned renders).
+- Third-party components take zero value dependencies; types are a one-line type-only import (declaration merging into `SessionStandardProps` / `SessionMaybeStandardProps`).
+
+### The read-only queue mirror
+
+- The MuxFrame `session/queued`: the Session holds a read-only inbox mirror (previews truncated; steering retired by source match); queue frames never enter history — pure stream state, cleared on reconnect and refilled from the new baseline; the never-instantiated window is buffered and replayed through the manager pendingBuffers.
+- Queue semantics: running does not lock input; ordinary messages queue through `session.prompt {mode:'queue'}`, and commands never queue.
+
+### Host wire smalls
+
+- The summary `blank` column and the `host/session-added` frame's `blank` field (see the blank bit above).
+- The SSE frame `host/commands-changed` (a pure invalidation signal); the client routes it into the typed events `commands/changed` and `connection/reset` (broadcast after each connection generation is established; wire-derived caches uniformly treat prior state as stale).
+- `command.list/execute` and `skill.list` are uniformly single-addressed by `sessionId` (a session always has an Agent; `agentFor`'s resume semantics come ready-made); the command-surface narrative lives in the [command surfaces note](2026-07-25-web-command-surfaces-and-assembly.md).
+- The `session.create` request shape: workspaceId/cwd as either-or, plus an optional caller-preallocated sessionId (a same-id same-cwd retry is idempotent; a different cwd reports `session-conflict`).
+
+## Alternatives considered
+
+| Rejected | One-line reason |
+|---|---|
+| A client-local Intent + materialize (published CAS / the pendingPrompt attach transaction / the before-create chain) | The client is forced to simulate the first half-life the host lacks, breeding a pile of state machinery — published CAS, the attach transaction, partial publication |
+| Host-reserved IDs (a draft Map) | The host merely acknowledges a number; the state machine stays on the client untouched |
+| A host draft Session (a Session without an Agent) | Every host surface that looks up the Agent must fork for drafts; core would need an attachAgent seam plus late-written header cwd |
+| Binding an Agent before cwd (ungrouped) | Overturns the readonly header.cwd "created in" invariant, plus the launch-dir side-effect product trap |
+| Passing session context down through React Context | Plugins should hold one mental model across host and client; the scope mechanism is isomorphic to the host dsh-scope |
+| A `scopeTarget` carrier + fused dispatcher (mirroring the host `agentEvents`) | The host wrapper layer guards the business Agent subject against drifting from the scope key; client events have no subject to guard — the filter on the actx plus cordis primitives covers every need |
+| Sessions not holding a ctx (a cordis-free object layer) | A red line born only so the filtering unit tests avoid importing cordis, at the cost of two-hop contribute callbacks plus mutable public fields; the host Agent already holds loopCtx |
+| Resident Session instances (resident-instance) | The host session log is the durable truth; residency is mere identity convenience, and its misalignment with the scope lifecycle is a source of complexity |
+| Components receiving wiring-callback bundles (two-layer inject→props pass-down) | The standard-kit channel lets components fetch their own; the public surface converges to hooks + stable props |
+| Swapping the no-session Hero view for the entire session Conversation | Even with the outer layout unchanged, the Hero, picker, and composer subtrees would remount together, making the whole UI region jump |
+| Making InputBar itself `session-maybe` | The input state machine, keyboard command surface, and actions would all have to accept absent values; replacing only the disabled input body keeps optionality at the shell boundary |
+| A dedicated conversion frame | `session-status(running:true)` semantically implies conversion (a blank session never runs); adding a frame buys zero information for one more wire type |
+
+## Consequences
+
+- Plugins gain session context isomorphic to the host's: per-session state hangs on the actx and mounts/tears down in one piece with the scope fiber, making leaks structurally impossible; two-session isolation is structurally guaranteed by the scope filter.
+- The client object layer converges to a wire mirror: session identity, lifecycle, and capability adjudication all defer to the host entity — the input system (the next layer) always faces a session with a real Agent, and providers like slash/skill uniformly address by sessionId directly.
+- Blank-session governance takes zero dedicated mechanisms: state rides one derived bit, visibility rides the unified list projection (only the current blank shows, as `New Session`), reclamation rides lazy persistence's existing contract (evaporation on restart), and the ordinary ceiling rides same-Workspace reuse.
+- The cost: the id→ctx handoff discipline and provide's Concurrent discipline are conventions rather than type-enforced, pinned by review and tests; fully disabled input while no workspace is picked is an experience cost the product surface accepts (the price of the single state axis).
+- Known gaps: approval/question recovery across prune (TODO); model selection returns in live-mutation shape (the host `selectModel` trio is ready-made, awaiting its own branch).

+
+## 问题
+
+web client 只有一张全局会话面：slot 全部从根 context 渲染，插件拿不到「当前是哪个 agent/session」的语境；draft 真身埋在 Session 对象里，任何要参与输入的插件都无处下手。要支撑命令/输入体系，平台层必须先回答：
+
+- 会话交互态（菜单、popup、草稿、在途请求）归谁持有，双会话如何结构性隔离；
+- 「新会话」在 host 实体存在之前是什么——client 要不要为它造一段独立生命；
+- session-scope 组件如何「自己拿会话数据」，而不是层层下传 props；
+- 用户放弃的新会话在 host 侧留下什么，谁来收。
+
+硬约束：host 是唯一真源；一切注册走 `ctx.effect` disposer；scope 机制与 host 的 Agent scope 架构一致；模型可见 ⟺ 已入 session log。
+
+## 决策
+
+### 对等模型：client 与 host 同一根状态轴
+
+host 侧 `session.create(workspaceId)` 一体产出 Session + Agent + cwd（原子大礼包，不拆）；client 侧就是这次出生的镜像——会话行进入 list mirror 的瞬间，client 为它铸 Agent scope（actx + provide + 输入面全套挂上）：
+
+- 会话身份自出生即为 host 真身：sessionId 由 `session.create` 响应 / `host/session-added` 帧带来，client 侧一切寻址（scope tag、slot store 键、RPC 地址）用的都是同一个 id。
+- 实体化时点 = 用户选定 Workspace（cwd 确定）的瞬间：client 当场调 `session.create({workspaceId})`，拿到完整实体。
+- 「New Session 且未选 workspace」是**纯视图态**（一个导航位置），不对应任何 session/scope 实体；选定之前 composer 整体锁死（无 slash、无纯文本）。
+- 「空会话」就是一个日志还空着的普通实体化会话；对 host 上所有 Agent-scope 插件（goal/plan/skill/…）它与任何会话无异，slash/plan 天然全活。
+
+### Agent scope：actx 是 client 侧 cordis 世界的唯一会话载体
+
+runtime `agents/scope.ts` 与 host `dsh-scope` 机制层一致（fiber + tag + filter 过滤；不 value-import：host 包携带 scoped-events 的 `Events` merge，进 client program 撞 Context merge）：
+
+- `createScope(ctx, key)`：no-op plugin fiber + `extend({[kScope]: key, [Context.filter]: …})`——filter 直接住 actx：untagged listener 全局可收，tagged 只收本 scope。
+- 派发就是 cordis 原语，thisArg = actx 本身：`actx.bail(actx, event, req)` / `actx.emit(actx, event, payload)`。
+- `Session.bindScope(actx)`：resolve 铸 scope 时单次配对（重复绑 throw；dropScope unbind），镜像 host `Agent.loopCtx`——Session 用它自行派发 scoped 事件。actx→Session 反向走 `sessions.sessionOf(actx)` 一跳（镜像 host 插件 `agent.session` 用法）。
+
+与 host dsh-scope 的有意分歧三条：
+
+- filter 住 actx 自身而非独立 carrier：host 包装层护的是「业务 Agent subject 与 scope key 不漂移」（host 事件首参注入 Agent 本体），client 事件 payload 只带 id、无 subject 可护。
+- key 用品牌 `SessionId` 值比较而非对象身份：host 里 agent.id === session id（1:1 同轴），agent 身份直接复用 `SessionId` 品牌，client scope 的身份即 wire id。
+- client 是 **Agent 身份** scope 而非活对象 scope：cold 会话期 host Agent 对象已 dispose 而 client actx 存活（视野内）——身份轴严格对等、对象冷热有意不同步。
+
+id→ctx 换乘只许三类位置（业务 provider 永不换乘）：
+
+- slot inject 工厂：ctx 不进渲染层，slot 框架交给组件的身份就是 sessionId，经服务 map 换回对象/controller。
+- root 协调服务自寻址：从投影的 sessionId 经 `sessions.scope(id)` 找回 actx。
+- root untagged listener：按 payload 的 sessionId 查自有 store。
+
+### scope 生命周期：挂靠 list mirror，出生即视野、死亡即 prune
+
+Session 实例与 scope 同生命周期，存活资格 = host listed（一个判据，mint 与 prune 共用）：
+
+- 出生 = 会话行进入 client 视野（list 基线拉取 / `create()` 本地回声 / `host/session-added` 帧），lazy 首次 resolve 铸 scope（resolution 纯函数、渲染安全）。
+- prune 一次同拆三样：Session 实例、scope fiber（级联挂在 actx 上的一切消费者）、session-keyed slot store。staged session（= `list.current`）例外：被移除仍在台上时保留冻结只读视图，stage 移走才拆。
+- 重开 = lazy 重建实例 + `open()` 拉 history（host session log 是持久真相）。
+- 遗留 TODO：approval/question 帧不进 history，跨 prune 不可恢复（manager 级 pendingBuffers 只覆盖「从未实例化」窗口）。
+
+### blank 位：空会话的可见投影、转正与复用
+
+「实体化但无首讯」的会话经 summary 派生位 `blank` 治理（派生列而非 header 字段，SessionHeader 保持不可变）：
+
+- host 判据：`session.events.length === 0`（零日志事件 = 尚无用户消息）。live 会话 `summarize()` 内存直读；cold 会话恒 `false`——lazy-create 契约保证 never-appended 会话根本不进 `persistence.list()`（JSONL/SQLite 两后端均已实证真 lazy），blank 从不落盘。
+- wire 承载两处：`SessionSummary.blank` 必填列；`host/session-added` 帧必填 `blank` 字段（创建时恒 true，供别的 tab 按同一空会话状态入镜像）。
+- client 镜像只降不升（单调），三来源翻转，全部复用既有 wire 信号：
+  - 发送方本地：首次 `prompt()` 的**成功响应**翻 false（受理即证明 user/message 已入 host 日志——此点翻转是确证而非乐观；`onEngaged` 同步更新列表镜像，当前 `New Session` 行原地转为普通标题，不新增列表行）。首讯被拒则会话保持 blank：与 host 权威对齐、继续显示为 `New Session`、保持 connectWorkspace 复用资格。
+  - 其他端：`host/session-status (running:true)` 帧翻转——blank 会话从不 running，首次 running 必然已非 blank；
+  - 重连对齐：`session.list` 的 summary.blank 是权威，错过帧的端下次拉取自然对齐；陈旧的 blank:true 不能把已转正的会话重新标回 blank。
+- 列表纪律：store 保留全部行；Workspace browser 的分组、平铺、搜索和计数共用同一可见投影——所有非 blank 会话都显示，blank 会话只显示 `session.id === sessions.current` 的一条，并强制标题为 `New Session`。切换 Workspace 后，旧 blank 实体仍在镜像中但从列表隐藏，目标 Workspace 的 current blank 显示；因此用户可见面全局至多一条 blank 行。
+- 残留账零 GC：刷新后 blank 会话带位回来，下次同 workspace 复用，普通单端路径使每个 workspace 至多保留一个；host 重启后 blank 无盘痕自然蒸发；多 tab 竞态多出的空壳只会成为非 current 隐藏行，后续复用消化，不做协调。
+
+### connectWorkspace：New Session 的唯一入口
+
+`workspaces.connectWorkspace(workspaceId): Promise<SessionId>`（归属 WorkspacesService——它同时持有 workspace 规范 path 与 sessions 引用）：
+
+- 复用臂：list mirror 中找 `blank && cwd == workspace.path`（host realpath 规范 canon 直等比较），命中直接返回该 id，不新建。
+- 新建臂：未命中则 `session.create({workspaceId})`，返回新 id。
+- 未知 workspaceId fail loud（不静默创建到别处）。
+- 解析保证（两臂同契约）：promise resolve 时返回的 id 已在 list store 且 `sessions.binding(id)` 同步可解析——`SessionsService.create` 在 RPC 成功后同步投影列表再 resolve，使 draft 搬运方可以在 open 之前往新 scope 的 machine 写文本，不等 notifier flush。
+- 调用方拿 id 自行 `sessions.open`；首讯发送就是普通 `session.prompt`——会话本来就在，失败即普通 prompt 失败，draft 文本还在 machine 里，重试即再次发送。
+- 全局 New Session 按钮默认取 `recentWorkspaceId`：先比较各 Workspace 内 Session 的最新 `updatedAt`，无 Session 时回退 Workspace `createdAt`，同值保持 Host 顺序；只有完全没有 Workspace 时才 `sessions.clear()` 进入无 session 视图。Workspace 分组内的创建动作仍显式命中该 Workspace。
+- runtime 启动时订阅首次完整基线：若已有恢复成功的 current session 则保持不动，否则自动 `connectWorkspace(recentWorkspaceId)` 并 open 返回的 blank session。该策略只结算一次；之后用户主动 clear 不会再次被自动选择覆盖，连接失败则等下一次基线投影重试。
+- blank Hero 中改选 Workspace 也走 `connectWorkspace`；若目标 id 与当前 id 不同，先把当前 input machine 的非空 draft 搬到目标 scope，再 `sessions.open(nextId)`。旧 blank 实体不删除，只因不再 current 而从列表隐藏。
+
+### per-session 供数：`sessions.provide` 标准件通道
+
+session slot 组件「自己拿 session 数据」的唯一供数路径。插件以静态描述符 `sessions.provide({hooks, props, resolve})` 声明固定键表（重名 key 注册时 throw），`resolve(binding)` 在确定 session 下物化值并随 scope 拆；web-react `standardKit` 统一循环把 hooks 格绑成 `use<Name>` 选择器 hook（`observableHook`→uSES，防 tearing）、props 格原样透传。
+
+slot scope 是闭集 `root | session-maybe | session`：
+
+- `root` 只拿全局标准件，不接收 session 身份或供数。
+- `session-maybe` 跟随 current session，但组件实例不因 id 有无或切换而换 key；无 session 时 `sessionId`、`useSession`/`useInput` 的选择结果及 `inputActions` 均可缺省。根部无 key 的 `SessionMaybeProvider` 驱动这条更新，`SessionMaybeProvideInfo` 靠静态键表在无 session 时仍保留完整 hook/prop 形状。
+- `session` 保证 `sessionId`、所有 hook source 与 props 均存在；每个严格 entry 的错误边界以 `sessionId` 为 key，切换 session 会重建该 entry 及其 session store。
+
+`conversation` 是 `session-maybe` 的常驻外壳：`ConversationRoot`、HeroShell、Workspace picker、composer stack 与 overlay chain 的 fallback 外框在无 session → blank session 的切换中保持 React 实例；`conversation.session` 只承载严格 session 的 header/view，composer 与各输入 slot 也保持严格 `session`。无 session 时 composer stack 直接放纯展示的 `DisabledInputBar`，session 出现后把输入体换成严格绑定的 InputBar；textarea 允许重建，Hero 与布局骨架不重建。blank → engaging/active 仍在同一严格 session subtree 内，InputBar 不因 phase 翻转而重建。
+
+- runtime 内建第一条：`'session'` hook——`useSession` 本身走同一机制，无特判。
+- Concurrent 纪律：渲染平面只从 hooks 格读（uSES 一致性保证）；props 格回调只在事件 handler 空间用；描述符解析 render-safe（幂等缓存、废弃渲染残留由 prune 收尸）。
+- 第三方组件值零依赖，类型一行 type-only import（declaration merging 进 `SessionStandardProps` / `SessionMaybeStandardProps`）。
+
+### 队列只读镜像
+
+- MuxFrame `session/queued`：Session 持只读 inbox 镜像（预览截断、steering 按 source 匹配退休）；queue 帧不进 history，纯 stream 态——重连清空、新基线重灌；未实例化窗口经 manager pendingBuffers 缓冲重放。
+- 队列语义：running 不锁输入；普通消息经 `session.prompt {mode:'queue'}` 排队，命令永不排队。
+
+### host wire 小件
+
+- summary `blank` 列与 `host/session-added` 帧 `blank` 字段（见上文 blank 位）。
+- SSE 帧 `host/commands-changed`（纯失效信号）；client 路由为类型事件 `commands/changed` 与 `connection/reset`（连接代建立后广播，wire 派生缓存一律视旧态为 stale）。
+- `command.list/execute`、`skill.list` 一律 `sessionId` 单址（会话恒有 Agent，`agentFor` 的 resume 语义现成）；命令面叙述见[命令业务面 note](2026-07-25-web-command-surfaces-and-assembly.md)。
+- `session.create` 请求形状：workspaceId/cwd 二选一 + 可选调用方预分配 sessionId（同 id 同 cwd 重试幂等，异 cwd 报 `session-conflict`）。
+
+## Alternatives considered
+
+| 弃案 | 一行理由 |
+|---|---|
+| client-local Intent + materialize（published CAS / pendingPrompt attach 事务 / before-create 链） | client 被迫模拟 host 缺失的前半段生命，养出 published CAS、attach 事务、部分发布一坨状态机 |
+| host 预留 ID（draft Map） | host 只认了个号，状态机原封留在 client |
+| host draft Session（有 Session 无 Agent） | 每个查 Agent 的 host 面都要为 draft 分叉；core 要开 attachAgent 缝 + header cwd 后写 |
+| 无 cwd 先绑 Agent（ungrouped） | header.cwd readonly "created in" 不变性被推翻 + launch-dir 副作用产品坑 |
+| React Context 层层传会话语境 | 插件在 host/client 两侧应是一个心智模型；scope 机制与 host dsh-scope 同构 |
+| `scopeTarget` carrier + 融合派发器（镜像 host `agentEvents`） | host 包装层护的是「业务 Agent subject 与 scope key 不漂移」，client 事件无 subject 可护；filter 住 actx + cordis 原语覆盖全部需求 |
+| Session 不持 ctx（对象层 cordis-free） | 只为筛选单测不引 cordis 而生的红线，代价是 contribute 两跳回调 + 可变公有字段；host Agent 本就持 loopCtx |
+| Session 实例常驻（resident-instance） | host session log 即持久真相；常驻仅为身份便利，与 scope 生命周期错位是复杂度之源 |
+| 组件收 wiring 回调包（inject→props 两层下传） | 标准件通道让组件自取；公共面收敛为 hooks + 稳定 props |
+| Hero 无 session 视图与 session Conversation 整支互换 | 即使外层 layout 不变，Hero、picker 与 composer 子树仍会一起重建，界面产生整块抖动 |
+| 让 InputBar 自身变成 `session-maybe` | 输入状态机、键盘命令面与动作都被迫接受缺省值；只替换 disabled 输入体能把可选性留在外壳边界 |
+| 专用「转正」帧 | `session-status(running:true)` 语义蕴含转正（blank 会话从不 running），加帧是 wire 多一型换零信息 |
+
+## 后果
+
+- 插件获得与 host 同构的会话语境：per-session 状态挂 actx、随 scope fiber 一次拆装，泄漏结构性不可能；双会话隔离由 scope filter 结构性保证。
+- client 对象层收敛为 wire 镜像：会话身份、生命周期、能力判别全部以 host 实体为准——输入体系（下一层）面对的永远是「有真 Agent 的会话」，slash/skill 等 provider 一律以 sessionId 直接寻址。
+- 空会话治理零专用机制：状态靠一个派生位，可见性靠统一列表投影（仅 current blank 以 `New Session` 展示），回收靠 lazy persistence 的既有契约（重启蒸发），常规上限靠同 Workspace 复用。
+- 代价：id→ctx 换乘纪律、provide 的 Concurrent 纪律都是约定而非类型强制，靠 review 与测试钉住；「未选 workspace」期间输入全禁是产品面接受的体验代价（单一状态轴换来的）。
+- 已知欠账：approval/question 跨 prune 恢复（TODO）；模型选择以 live-mutation 形状回归（host `selectModel` 三件套现成，等独立分支）。

+# Agent Note: Web command business surfaces and assembly (ui-command / ui-skill / ui-subagent)
+
+Status: implemented
+
+English | [中文](2026-07-25-web-command-surfaces-and-assembly.zh.md)
+
+> Scope: the command directory cache and three-kind dispatch (ui-command), the popup selection flow, the two skill / subagent reference sources, and fixture command routing plus assembly acceptance (the slash-flow snapshot). The carrying wire lives in the [session scope note](2026-07-25-web-client-session-scope-and-provide-channel.md); triggers, the menu, and the input machine live in the [input machine note](2026-07-25-web-input-machine-and-slash-pipeline.md).
+
+## Problem
+
+The pipeline was ready but command knowledge had no landing spot: host-side `ctx.commands` and `ctx.skills` were complete while the web channel had no command capability. The business layer had to answer:
+
+- Command UI takes more than one shape (execute on the spot, pop a select box, backfill and keep typing arguments) — how do business packages ship with zero skeleton changes;
+- When is the directory fetched: pulling on every menu open is too slow, while a resident cache needs invalidation and reconnect stories;
+- Sessions are always agent-backed (Session + Agent born in the same instant) — by what address does the client command surface honor the host's per-agent effective directory;
+- Assembly-level acceptance: with the layers split apart, how the user-visible main chain is pinned once they come together.
+
+## Decision
+
+### ui-command: a `CommandService` + a session-keyed `CommandDirectory` + a per-session `PopupSelectController`
+
+- The `ClientSessionContext { sessionId }` projection is self-held in the ui-slash contract (types.ts): sessions are always agent-backed, so session identity is the entire projection of command capability; the wire addresses by `{sessionId}` (both `command.list` and `command.execute`; the host resolves the Agent from the session header).
+- The directory is compartmented by `SessionId`, with per-key single-flight + an epoch guard (an old pull never overwrites newer state); `commands/changed` soft-invalidates every key (the old snapshot keeps serving while the repull runs in the background), `connection/reset` hard-invalidates every key and rewarms, Enter strong-waits on the current key, and a failure keeps the draft with no downgrade. Prewarming hangs on the source's `warm` hook — once over the full roster at scope birth, which covers the entire session lifecycle (session capability is constant from birth).
+- `register(contribution)` registers client commands (a descriptor + `available(projection)` + a popupSelect spec); candidate synthesis = the host directory + contribution availability filtering, then the query/position pass, and a host/contribution name clash fails loud.
+- The three command kinds derive from the registration surfaces; developers never declare positions: a host descriptor with `input` = **leadingInput** (backfill `/name ␣` + claim, keep typing arguments, leading position only); a client-registered popupSelect spec = **popupSelect** (the official select-box shell, business ships zero components); neither = **execute** (run on selection, zero UI).
+- The dispatch decision table: the menu can trigger all three kinds; Space recognizes only leadingInput (the misfire defense: irreversible side effects keep explicit entry points only); Enter runs execute / opens the shell only on a bare token, while leadingInput tolerates trailing arguments.
+- The popup from `popupFor(actx)`: search filters locally, select is single-flight, the projection is captured at open, onSelect consumes the token through the consume-token event only on success, a failure is retained for retry, and a session switch merely hides it. The popup shell is a transient layer (never in the state machine): the box holds focus, Enter/↑↓/Escape belong to it, and clicking outside the box dismisses (clicking the textarea also returns focus).
+
+### Reference sources (seeing only projections plus their own apply closures, on the root ctx)
+
+- **ui-skill**: `skill.list({sessionId})` addresses by session (the host resolves the project root from the session header); the directory cache is single-flight keyed by sessionId, prewarmed at birth by the `warm` hook and fully cleared by `connection/reset`. A pick produces a text outcome (the literal `/name ` text, Decision 21); `lexicon` supplies the roster from CatalogFetch's settled snapshot (`undefined` while not warm). No match hook (references never enter command adjudication). Skill references ride ordinary prompts as literal text (outside the command plane; tool-skill unchanged, with the session-prefix directory providing the cooperative association).
+- **ui-subagent**: candidates are zero-RPC (the sessions.list snapshot filtered by parentId/running); a pick produces a text outcome (the literal `@name ` text); `lexicon` derives from the same snapshot (the model-side representation awaits its business workstream).
+
+### Fixture command routing and assembly
+
+- The connection fixture adds command routing (fixture + fake-api): the keyless rig can run the complete command flow (directory, execution, popup selection).
+- The apps/cli assembly mounts all the new packages; the tsconfig path map / reference sets are filled in; catalogs/docs are regenerated with the wire and events.
+
+### Assembly-level acceptance: the slash-flow snapshot
+
+`apps/web/tests/slash-flow.snapshot.ts` pins the user-visible main chain (assembled keyless; package mocks are no substitute for the assembled transcript): the composer disabled with no session → creating a Workspace and entering an already-materialized blank session → picking the `/echo` leadingInput from the `/` menu → the command executes but the blank bit does not flip and the list still shows `New Session` → the first ordinary prompt's successful acceptance converts that same row; the same session-bound textarea holds across blank → active. `workspace-flow.snapshot.ts` separately pins blank-row creation/reuse, first-prompt rejection backfill, and — on a Workspace switch before the first prompt — the draft moving across input machines with the old blank row hidden.
+
+## Alternatives considered
+
+| Rejected | One-line reason |
+|---|---|
+| Inline prompt dispatch (command text riding the message into the host for parsing) | Conflates the command and message planes; command execution being independent of the message queue is existing host semantics |
+| A bridge materializing skills as commands | Skills have their own directory; N registrations would be a detour; the tag form naturally avoids the command plane |
+| A `skill.invoke` RPC | The host has no such operation; skill references are plain text riding prompts |
+| A new ContentBlock reference type | Full-chain cost (adapters/UI/compaction); text-as-truth plus structured occurrence records suffices |
+| Client packages self-reporting command directories | The host is the single source of truth; the client only reads descriptors, with `commands-changed` pushing invalidation |
+| The `requires: 'none' \| 'agent'` discriminant axis (an agentless directory + dual-addressed queries) | With sessions always agent-backed, the amphibious command has no owner; the whole axis reverts to master's shape, to be reopened on real demand |
+| Dedicated commandresult / commandpanel slots | Results go through notices; the popup shell is a skeleton-internal overlay; rich result cards sit in the ledger |
+| An agent-type directory as the `@` source | No type registry exists; the live-session snapshot already covers it |
+| A PickAction/EnterCommand class family (class-inheritance pick products) | Cross-package runtime values break client bundle purity; pure data interfaces plus closure methods are equivalent |
+
+## Consequences
+
+- Shipping a business command = a host registration plus one client `command.register` (popupSelect) or zero registration (execute/leadingInput derive automatically), with zero skeleton changes; the cost is that the three-kind semantics concentrate in ui-command, and a hypothetical fourth kind means changing it.
+- The resident directory cache plus push invalidation buys zero-latency menus and reliable enter adjudication; the cost is three invalidation paths (the change frame, reconnect, the epoch guard) that all need tests pinning them.
+- sessionId addressing puts the host's per-agent effective directory (global + scoped shadows) straight on the wire, with the client presenting it as-is.
+- Known gaps: the popupSelect shell has no shipped business consumer yet (model selection and its kin return with #600's host `selectModel` in live-mutation shape, serving as the onboarding template then); the queue's second cut (per-item Inbox operations), rich result cards, and roster configurability sit in the ledger awaiting their triggers.

+# Agent Note: Web 命令业务面与装配（ui-command / ui-skill / ui-subagent）
+
+Status: implemented
+
+[English](2026-07-25-web-command-surfaces-and-assembly.md) | 中文
+
+> 范围：命令目录缓存与三型判定（ui-command）、popup 选择流、skill / subagent 两个引用源、fixture 命令路由与装配验收（slash-flow 快照）。承载 wire 见[会话作用域 note](2026-07-25-web-client-session-scope-and-provide-channel.md)；触发/菜单/输入机器见[输入状态机 note](2026-07-25-web-input-machine-and-slash-pipeline.md)。
+
+## 问题
+
+管线就绪但没有命令知识的落点：host 侧 `ctx.commands` 与 `ctx.skills` 完整而 web 通道无命令能力。业务层要回答：
+
+- 命令 UI 不止一种形态（当场执行、弹选择框、回填后继续打参数）——业务包如何零骨架改动上架；
+- 目录何时拉取：每次开菜单现拉太慢，常驻缓存就要有失效与重连故事；
+- 会话恒 agent-backed（Session+Agent 同瞬出生），client 命令面以什么地址兑现 host 的 per-agent 有效目录；
+- 装配级验收：拆开的各层合起来，用户可见主链如何钉住。
+
+## 决策
+
+### ui-command：`CommandService` + session 键控 `CommandDirectory` + per-session `PopupSelectController`
+
+- 投影 `ClientSessionContext { sessionId }` 自持于 ui-slash 契约（types.ts）：会话恒 agent-backed，会话身份即命令能力的全部投影；wire 以 `{sessionId}` 寻址（`command.list` / `command.execute` 均是；host 从会话 header 解析 Agent）。
+- 目录按 `SessionId` 分格，per-key single-flight + epoch guard（旧拉取永不覆盖新态），`commands/changed` 全 key 软失效（旧快照继续服务、后台重拉）、`connection/reset` 全 key 硬失效并预热，Enter 强等当前 key、失败留草稿不降级。预热挂 source 的 `warm` 钩子——scope 出生时对全 roster 一次，即覆盖整个会话生命周期（会话能力自出生恒定）。
+- `register(contribution)` 注册 client 命令（descriptor + `available(projection)` + popupSelect spec）；候选合成 = host 目录 + contribution 可用性过滤，再过 query/position，host/contribution 重名 fail loud。
+- 命令三型按注册面派生，开发者不声明位置：host descriptor 带 `input` = **leadingInput**（回填 `/name ␣` + claim，继续打参数，仅限行首）；client 注册 popupSelect spec = **popupSelect**（官方选择框壳，业务零组件）；两者皆无 = **execute**（选中即执行，零 UI）。
+- 判定决策表：菜单可触发三型；Space 只认 leadingInput（误触发防线：不可逆副作用只留显式入口）；Enter 裸 token 才 execute/开壳、leadingInput 容忍尾随参数。
+- `popupFor(actx)` 的 popup：search 本地过滤、select single-flight、open 时捕获投影、onSelect 成功才经 consume-token 事件消 token、失败保留可重试、session 切换只隐藏。popup 壳是瞬态层（不进状态机）：框持焦点、Enter/↑↓/Escape 归它、点框外即 dismiss（点 textarea 同时归还焦点）。
+
+### 引用源（只见投影 + 自家 apply 闭包的 root ctx）
+
+- **ui-skill**：`skill.list({sessionId})` 按会话寻址（host 从会话 header 解析项目根）；目录缓存按 sessionId 键控 single-flight，`warm` 钩子出生预热、`connection/reset` 全清。pick 产出 text outcome（`/name ` 原文，决策 21）；`lexicon` 从 CatalogFetch 的 settled 快照给名录（未热 `undefined`）。无 match 钩子（引用不进命令裁决）。skill 引用以原文随普通 prompt 走（命令平面之外；tool-skill 不变，session-prefix 目录提供协作关联）。
+- **ui-subagent**：候选零 RPC（sessions.list 快照按 parentId/running 过滤）；pick 产出 text outcome（`@name ` 原文）；`lexicon` 同快照派生（模型侧表示待业务立项）。
+
+### fixture 命令路由与装配
+
+- connection fixture 补命令路由（fixture + fake-api）：keyless 台架可跑完整命令流（目录、执行、popup 选择）。
+- apps/cli 装配挂全部新包；tsconfig path map / reference 集补齐；catalog/docs 随 wire 与事件再生成。
+
+### 装配级验收：slash-flow 快照
+
+`apps/web/tests/slash-flow.snapshot.ts` 钉住用户可见主链（assembled keyless，包 mock 不替代装配转录）：无 session 时 composer 禁用 → 创建 Workspace 并进入已实体化的 blank session → `/` 菜单选 `/echo` leadingInput → 命令执行但 blank 位不翻转、列表仍显示 `New Session` → 首条普通 prompt 成功受理后同一行转正；同一 session-bound textarea 跨 blank → active 保持。`workspace-flow.snapshot.ts` 另钉住 blank 行创建/复用、首讯拒绝回填，以及首讯前切换 Workspace 时 draft 跨 input machine 搬运且旧 blank 行隐藏。
+
+## Alternatives considered
+
+| 弃案 | 一行理由 |
+|---|---|
+| prompt 内联派发（命令文本随消息进 host 解析） | 混淆命令/消息平面；命令执行独立于消息队列是既有 host 语义 |
+| skill 物化为 command 的桥 | skill 自有目录；N 笔注册是绕路；标签形式天然避开命令平面 |
+| `skill.invoke` RPC | host 无此操作；skill 引用是随 prompt 的普通文本 |
+| 新 ContentBlock 引用类型 | 全链路成本（adapter/UI/compaction）；文本即真身 + 结构化 occurrence 记录已足够 |
+| client 各包自报命令目录 | host 是唯一真源；client 只读 descriptor，`commands-changed` 推失效 |
+| `requires: 'none' \| 'agent'` 判别轴（agentless 目录 + 双址查询） | 会话恒 agent-backed 后两栖命令无 owner；整轴回退 master 形状，待真需求重开 |
+| 专用 commandresult / commandpanel 坑位 | 结果走 notice；popup 壳是骨架内浮层；富结果卡入台账 |
+| agent-type 目录做 `@` 源 | 无类型注册表；live-session 快照已覆盖 |
+| PickAction/EnterCommand 类族（类继承 pick 产物） | 跨包运行时值破坏 client bundle 纯度；纯数据接口 + 闭包方法等价 |
+
+## 后果
+
+- 业务命令上架 = host 注册 + client 一笔 `command.register`（popupSelect）或零注册（execute/leadingInput 自动派生），零骨架改动；代价是三型语义集中在 ui-command，假想的第四型意味着改它。
+- 常驻目录缓存 + 推失效换来菜单零延迟与回车裁决可靠；代价是三条失效路径（change 帧、重连、epoch guard）都需测试钉住。
+- sessionId 寻址让 host 的 per-agent 有效目录（全局 + scoped shadows）直接上 wire，client 原样呈现。
+- 已知欠账：popupSelect 壳暂无已上架业务消费者（模型选择等 #600 的 host `selectModel` 以 live-mutation 形态回归，届时作接入样板）；队列第二刀（逐项 Inbox 操作）、富结果卡、roster 可配置性入台账待触发。

+# Agent Note: Web input state machine, composer slots, and the slash pipeline (ui-conversation input / ui-slash)
+
+Status: implemented
+
+English | [中文](2026-07-25-web-input-machine-and-slash-pipeline.zh.md)
+
+> Scope: the input state machine (the occurrence table + claim watch + the submit transaction), the hub/facade and send orchestration, the three scoped bail events for cross-plugin input rewrites, `/` and `@` trigger detection and the menu pipeline (ui-slash), and the slot system around the composer. It depends on the [session scope note](2026-07-25-web-client-session-scope-and-provide-channel.md)'s sctx / provide / session-maybe and blank entity model; command knowledge (the three kinds, the directory, popups) is untouched here — that is the [command surfaces note](2026-07-25-web-command-surfaces-and-assembly.md)'s territory.
+
+## Problem
+
+Two composers, each a law unto itself: hero (EmptyState, the controlled chain writing straight into the Session) and the in-conversation InputBar (a plain controlled textarea) — behavior, draft ownership, and send path all inconsistent. To bring the three trigger families — `/` commands, skill references, `@` references — onto the input surface, these had to be answered:
+
+- How the three trigger families layer, and who holds knowledge of "commands" versus who stays zero-knowledge;
+- How the input box expresses "command mode" — derived from the draft text or explicit state? What do backspace, enter, space, and pasting a whole line each mean;
+- Submission is an asynchronous transaction (an RPC round trip) — how are stale-result backwash, session switching, and React concurrent replay defended;
+- How reference chips are represented on a plain textarea, and who owns undo / clipboard / paste matching / model serialization;
+- How cross-plugin input rewrites (menu backfill, reference insertion, token consumption) achieve dependency inversion;
+- Which React shells must be reused across no session → blank session, and which strict-session input bodies may be replaced.
+
+Hard constraints: components mount through slots only; presentation artifacts never enter the session log; the keyboard path is IME-safe throughout.
+
+## Decision
+
+### The input state machine (`InputMachine`)
+
+A pure state machine, events in / effects out, clock injected. Four phases (plain / adjudicating / claimed / submitting). Command mode is **never derived from the draft**; the pick paths establish it explicitly at discrete moments; the claim is watched by `draft.startsWith(token)`, with a backspace break releasing automatically; the claim shape is `{token, hint?}` (hint feeds ghost text).
+
+The event surface (`dispatch(ev)` is the single write entry; one transaction per event):
+
+- `draft-changed {draft, editRange?}` — the textarea's full draft; editRange narrows the occurrence-shift computation, defaulting to a shared prefix/suffix scan.
+- `newline {selection}` — the Ctrl+Enter line break (not via the browser's execCommand: under self-managed undo a browser write forks two histories).
+- `begin-command {claim, span}` / `insert-ref {reference, span}` / `consume-token {guard}` — the machine side of the three bail events; span CAS = draftRev equality.
+- `set-invalid {invalidIds}` — the style bit for owner-resolution results (not a transaction).
+- `undo` / `redo` — the self-managed transaction log (a ring of 100; single-character typing merges within injected-clock windows; a successful submit clears the log).
+- `paste-begin {text, selection, components?, generation?}` — the paste plus hot-snapshot synchronously matched components in one transaction (one Undo returns to before the paste); opens a PasteMatchAttempt.
+- `paste-upgrade {attemptId, span, reference}` — an asynchronous match upgrade as its own transaction (Undo in two steps); the attempt stays current, and insertedRange shrinks with each upgrade.
+- `invalidate-paste` — attempt-ending gestures observed at the DOM layer (caret/selection operations and the like).
+- `enter {mode}` / `adjudicated` / `adjudication-failed` / `submit-settled` / `release` — the submit-transaction plane: a SubmitAttempt (seq + AbortSignal) blocks backwash; success commits and clears the draft; failure rolls back under the drift guard (the enter-time snapshot is backfilled only while the live draft still equals it; if the user has typed again, only a notice fires).
+
+The effect surface (executed by the shell): `adjudicate` (calls SlashController.adjudicate), `begin-submit` (the claim.submit transaction), `default-sink` (ordinary messages, hub-orchestrated), `notice`.
+
+The occurrence table and the chip's three projections:
+
+- Each reference occupies one `U+FFFC` in the draft; a table entry is `{occurrenceId, source, ref, offset, label, clipboardText, invalid?}`; same-named chips stay independent through occurrenceId.
+- Every edit updates the draft and the table in one transaction: ranges shift; a deletion/replacement intersecting a placeholder acts on the whole chip.
+- The single-character placeholder makes keyboard atomicity mostly hold natively (the caret has no interior position; Backspace / arrow keys / Shift extension natively take the whole chip); a mouse click on a chip goes backdrop hit → whole-chip setSelectionRange.
+- The visual projection = label: the backdrop renders the chip at the placeholder offset (the textarea glyph is invisible), with invalid taking the invalid style.
+- The clipboard/persistence projection = clipboardText: copy/cut expands placeholders inside the selection; the draft-persistence mirror writes the same projection (the chat store always holds plain text; the refresh seed semantics = select-all copy → reopen → paste, with chips degrading to text across a refresh).
+- The model projection = generated per chip at submit through the source's `codec.serialize` (owned by the submit attempt's signal and stale guard; a missing owner / failure / cancel means no send, never a downgrade to `/name`).
+
+### Cross-plugin input rewrites: three scoped bail events
+
+The contract is declared in ui-slash (the bottom of the dependency chain); producers dispatch via `sctx.bail(sctx, ...)`, and the only consuming side is the three listeners the hub hangs on the sctx when building the shell; returning `true` ⟺ the machine passed the phase and CAS guards and actually rewrote (emitting the event ≠ a successful modification; whether Space gets `preventDefault` follows the return value):
+
+- `slash/input-begin-command` `{claim, span}` — backfill of the command claim adjudicated from a menu pick / Space (dispatched by the SlashController).
+- `slash/input-insert-reference` `{reference, span}` — reference chip insertion (dispatched by the SlashController).
+- `slash/input-consume-token` `{guard: span | bare-token}` — consuming the command token after business success (dispatched by the downstream command surfaces).
+
+Calls that stay un-evented (registry registration → explicit call → await): Input's own draft/submit, asynchronous Enter adjudication, the reference serializer, the asynchronous paste matcher. `@mode bail` has entered the JSDoc parser and the cordis catalog gate (scripts/jsdoc.ts).
+
+### The slash pipeline (ui-slash: a root `SlashService` + a per-session `SlashController`)
+
+A trigger/menu/pick pipeline with zero knowledge of "commands":
+
+- The service holds only the source registry (`SlashSource{trigger: '/'|'@', name, candidates, onPick, matchSpace?, matchEnter?}`; (trigger,name) unique, registration order = group order = polling order) and `sessionOf(sctx)`. Implementing a match hook IS the declaration of participation in space/enter adjudication; the pipeline polls in registration order, the first non-undefined answer wins, and no claimant means the default sink. matchSpace is synchronous (space fires mid-keystroke; hot cache only); matchEnter is asynchronous (it may await the source's own warmup, and a warmup failure rejects).
+- The controller holds the single authoritative hit (span included; retained for Space after the menu closes), the per-session menu store, the candidate-fetch generation, keyboard arbitration (combobox mode: focus stays in the textarea, ↑↓/Enter/Escape are intercepted and all pass the IME composition guard, with the single exception Shift+Enter unconditionally going first), and pick orchestration (outcome → self-dispatched bail events); at each session scope's birth it runs `warm(projection)` once over the source roster — within that scope the projection holds only the stable sessionId, with no published/capability transitions; the scope disposer tears down the controller.
+- Trigger-detection word boundaries (`user@host` and URL `/` never trigger) and the guard tiers (plain: `/` everywhere + `@` inline / claimed: `/` suppressed, `@` live / frozen: none) are the frozen pure core.
+
+### hub / facade: the resident shell and the strict-session input body
+
+- The hub (trigger/decoration registries + send orchestration) takes the slash/command services as optional `ctx.get()` dependencies: without ui-slash or the command surfaces, input still sends and receives normally — graceful degradation.
+- Each materialized Session has exactly one `SessionInputShell` (the facade), created and torn down with the session scope; with no session, no input machine is built. `ConversationRoot` is itself the `session-maybe` resident shell, holding HeroShell, the Workspace picker, the composer stack, and the chain-fallback frame.
+- With no session the shell renders the presentation-only `DisabledInputBar`; once `connectWorkspace` returns a blank session, only the input body is swapped for the strict-session InputBar. The textarea may be rebuilt here, while `ConversationRoot`, the Hero, and the layout skeleton hold; blank → engaging/active stays the same session-bound InputBar, with the textarea never rebuilt on a phase flip.
+- ConversationRoot's Hero criterion is `sessionId === undefined || (composerPhase === 'blank' && (openState === 'open' || openState === 'loading'))`. The first submit enters engaging synchronously, and a failure keeps the composer and the error context rather than falling back to the blank Hero; the sidebar's blank bit flips false only after a prompt is successfully accepted.
+- Sending unifies in the hub defaultSink: after an optimistic draft clear it goes only through `session.prompt {mode:'queue'|'steer'}`; backfill happens only when it fails and the live draft is still empty — a user who has kept typing is never overwritten. No Draft materialize or attach transaction exists.
+- When the blank Hero re-picks the Workspace, the shell calls `connectWorkspace`; if the target session differs, the non-empty draft moves from the current shell to the target shell before the new id is opened, and the old blank session survives but is no longer current.
+- The Notifier's two-bit contract: `dirty` (snapshot freshness, clearable by an `ensureFresh` pull) and `notifyPending` (notification debt, cleared only by a flush) are mutually independent — a pull must not swallow a push, and object-layer push subscribers (watchTransaction) depend on this guarantee.
+
+### Plain-text references (Decision 21): text outcomes and lexicon decoration
+
+skill/@subagent references skip the placeholder + occurrence identity chain — a pick inserts the literal `/name ` `@name ` text straight into the draft, with the chip visual purely derived:
+
+- PickOutcome gains a `{text}` arm; the new scoped bail event `slash/input-insert-text` `{text, span}` (the same contract as the other three: draftRev CAS, returning true ⟺ an actual rewrite); facade.insertText goes through setDraft concatenation — zero machine changes.
+- Sources get an optional `lexicon?(session)` hook: a synchronous hot-snapshot name roster, with `undefined` = data not warm — zero decoration, never triggering a fetch (the render path stays synchronous and side-effect-free); the controller aggregates it into the `lexicon()` public surface.
+- `decorations.scanTextRefs`: a word-boundary scan of the draft (`/name`, `@name` at line start / after whitespace; `x/name` never hits) against the roster; a hit gets the `.textRef` mark (a pure range highlight on the backdrop, same as hlToken); an edit breaking the match shape simply disappears on the next scan.
+- Sending is the literal text (no more `<skill>` serialization); on the bubble side MessageItem decorates both shapes (the legacy `<skill>` tag + plain-text tokens).
+- The old occurrence/paste/serialize chain stays on disk in full, undeleted (additive; deletion is a separate future cut). Known limitation kept as-is: with the lexicon not warm at paste / cold start there is no decoration — it lights up only after typing `/` opens the menu once.
+
+### Per-session provide contributions and the private keyboard surface
+
+- ui-conversation (the hub doubling as a contributor) supplies through `sessions.provide` the `'input'` hook (machine state + the queue overlay) plus the `inputActions` prop (`setDraft`/`submit`, stable void callbacks).
+- The public/private boundary: the public provide carries only React-vocabulary members; the keyboard/DOM command surface (track/arbitrate/space/undo/redo/paste/dismissPopup/bindMirror — synchronous return values, disposer semantics) is InputBar-exclusive, passed privately in-package through the InputBar entry's own inject, never leaving the plugin boundary.
+
+### The slot system
+
+`conversation` is itself session-maybe; its session content and the composer input slots are strict session, while the Hero Workspace picker stays root. The child slots are all declared by ui-conversation's conversation registration:
+
+- `conversation.session` (single) — the strict-session header, view ring, and chat store; rebuilt when the session id switches.
+- `conversation.composer.bar` (single) — the slot for the InputBar itself: the InputBar is a true slot entry (self-registered into its own slot) and the content of the composer chain's fallback; it is not a chain entry — the chain's single election would unmount it on a takeover, breaking textarea DOM survival.
+- `conversation.input.overlay` — the floating-overlay anchor inside the input card; registrants' inject resolves each one's own per-session controller by the slot sessionId.
+- `conversation.input.dock` — the stacked strip above the input (QueueDock's read-only queue list lands here), ordered by `order`.
+- `conversation.composer.dock` — the stats band on the composer's top edge.
+- `conversation.input.left` / `conversation.input.right` — the tool-row left and right regions.
+- `conversation.input.plan` / `conversation.input.model` (single) — the tool row's two named control seats; the bar passes only `locked` (owner props), each stays empty until its owning plugin registers, no placeholder fallback.
+- `conversation.hero.workspace` (root scope) — the Workspace picker shared by the no-session and blank Hero; a pick reuses or creates the target blank session through `connectWorkspace`, moving the draft where necessary before switching current.
+
+### Testing discipline
+
+The state machine's entire behavior is covered by pure-JS unit tests (event sequences in, asserting state and effects, zero browser DOM); the interaction matrix is projection-tested row by row. This requirement is precisely what forced the pure-core + service-shell layering.
+
+## Alternatives considered
+
+| Rejected | One-line reason |
+|---|---|
+| An ActiveCommand intermediate state / a registerMode mode registry / deriving command mode from the draft | Claims are established explicitly by the pick paths — no table, no derivation |
+| Direct bindTarget/bindDraft object wiring | Reverse coupling plus root-singleton cross-session mispairing; scoped bail events preserve dependency inversion with structurally correct routing |
+| A unified slash/input-apply, or eventing everything | Three independent payloads cover the cross-plugin rewrites; asynchronous paths stay registry-based explicit calls |
+| contenteditable / a rich-text tree | Poor compatibility; textarea + U+FFFC + the occurrence table covers the full interaction contract |
+| Dual draft persistence {text, occurrences} | The mirror writing the clipboard projection adds zero new concepts; chip degradation across refresh is acceptable |
+| The native textarea undo stack | Unreliable under controlled + programmatic writes; the paste two-step undo semantics can only be self-managed |
+| The InputBar receiving a 16-member wiring-callback bundle | The consumption matrix proved 11 members InputBar-exclusive and 1 a dead member; the standard-kit channel lets components fetch their own, with the keyboard surface passed privately in-package |
+| Space adjudication also claiming execute-kind commands | The misfire defense: after a space the whole line is an ordinary prompt; irreversible side effects keep explicit entry points only |
+| A generic tokenPattern decoration mechanism | Structured occurrence records replace pattern scanning |
+| A placeholder select resident in the tool row | Named seats stay empty until registration; a placeholder clashing with the real implementation is two sources of truth |
+| All references through U+FFFC chips (the pre-Decision-21 line) | Plain text + derived decoration carries zero identity state; the literal text IS the model projection, sparing undo/clipboard any special cases; the chip chain is kept for scenarios needing indivisible atomicity |
+
+## Consequences
+
+- One resident conversation shell carries no-session/blank/active: no session → blank guarantees only the outer frame's React identity, allowing the disabled textarea to be replaced by the strict InputBar; the same blank session → engaging/active keeps the InputBar and the textarea. EmptyState and the controlled intent chain (`sessions.updateIntent`/`updatePendingPrompt`/`workspaces.sendSession`) are deleted along with their last consumer.
+- The input surface's zero knowledge of commands plus optional dependencies: pure input works without the command packages; `@` references and skill references get free reuse of the same menu/pick pipeline. The cost is that space/enter adjudication is a per-source polling protocol whose answer semantics (sync/async, the meaning of undefined) are a frozen contract.
+- Transactionalized submission (attempt seq + the drift guard) makes the three defect classes — stale-result backwash, session switching, concurrent replay — structurally impossible, pinned by the matrix tests.
+- Known gaps: chip fidelity across refresh (paste matching is reusable for it) has no workstream yet; the subagent reference's model representation awaits its business workstream.

+# Agent Note: Web 输入状态机、composer 坑位与 slash 管线（ui-conversation input / ui-slash）
+
+Status: implemented
+
+[English](2026-07-25-web-input-machine-and-slash-pipeline.md) | 中文
+
+> 范围：输入状态机（occurrence 表 + claim 看护 + 提交事务）、hub/facade 与发送编排、跨插件输入改写的三个 scoped bail 事件、`/` 与 `@` 触发检测与菜单管线（ui-slash）、composer 周边坑位体系。依赖[会话作用域 note](2026-07-25-web-client-session-scope-and-provide-channel.md)的 sctx / provide / session-maybe 与 blank 实体模型；命令知识（三型、目录、popup）零涉——那是[命令业务面 note](2026-07-25-web-command-surfaces-and-assembly.md)的领地。
+
+## 问题
+
+两个各自为政的 composer：hero（EmptyState，受控链直写 Session）与会话内 InputBar（普通受控 textarea），行为、draft 所有权、发送路径全不一致。要让 `/` 命令、skill 引用、`@` 引用三类触发进入输入面，必须回答：
+
+- 三类触发如何分层，谁对"命令"有知识、谁零知识；
+- 输入框如何表达"命令态"——从 draft 文本推导还是显式状态？退格、回车、空格、整行粘贴各是什么语义；
+- 提交是异步事务（RPC 往返）——晚到结果回灌、会话切换、React concurrent 重放如何防御；
+- 引用 chip 在纯 textarea 上如何表示，undo/剪贴板/粘贴匹配/模型序列化各归谁；
+- 跨插件的输入改写（菜单回填、引用插入、token 消费）如何做到依赖倒置；
+- 无 session → blank session 时哪些 React 外壳必须复用，哪些严格 session 输入体允许替换。
+
+硬约束：组件一律经 slots 挂载；呈现物不进 session log；键盘路径全程 IME 安全。
+
+## 决策
+
+### 输入状态机（`InputMachine`）
+
+纯状态机，事件进/效果出，注入时钟。四相 phase（plain / adjudicating / claimed / submitting）。命令态**永不从 draft 推导**，由 pick 路径在离散时刻显式建立；claim 由 `draft.startsWith(token)` 看护、退格破坏自动 release；claim 形状 `{token, hint?}`（hint 供 ghost text）。
+
+事件面（`dispatch(ev)` 单写入口，每个事件一个 transaction）：
+
+- `draft-changed {draft, editRange?}`——textarea 全量草稿；editRange 缩小 occurrence 平移计算，缺省前后缀共扫。
+- `newline {selection}`——Ctrl+Enter 换行（不经浏览器 execCommand：自管 undo 下浏览器写入会分叉双历史）。
+- `begin-command {claim, span}` / `insert-ref {reference, span}` / `consume-token {guard}`——三个 bail 事件的机器侧；span CAS = draftRev 相等。
+- `set-invalid {invalidIds}`——owner resolution 结果的样式位（非 transaction）。
+- `undo` / `redo`——自管 transaction log（环形 100；单字符打字按注入时钟窗合并；提交成功清 log）。
+- `paste-begin {text, selection, components?, generation?}`——粘贴 + 热快照同步匹配组件同 transaction（Undo 一次回粘贴前）；打开 PasteMatchAttempt。
+- `paste-upgrade {attemptId, span, reference}`——异步匹配升级为独立 transaction（Undo 两段）；attempt 保持 current，insertedRange 随升级收缩。
+- `invalidate-paste`——DOM 层观察到的 attempt 终结手势（caret/selection 操作等）。
+- `enter {mode}` / `adjudicated` / `adjudication-failed` / `submit-settled` / `release`——提交事务平面：SubmitAttempt（seq + AbortSignal）防回灌，成功 commit 清稿，失败带漂移守卫 rollback（回车时快照仅当 live draft 仍等于它才回填；用户已再输入则只发 notice）。
+
+效果面（shell 执行）：`adjudicate`（调 SlashController.adjudicate）、`begin-submit`（claim.submit 事务）、`default-sink`（普通消息，hub 编排）、`notice`。
+
+occurrence 表与 chip 三投影：
+
+- 每颗引用在 draft 中占一个 `U+FFFC`；表项 `{occurrenceId, source, ref, offset, label, clipboardText, invalid?}`；同名 chip 因 occurrenceId 独立。
+- 一切编辑同 transaction 更新 draft 与表：区间平移；与占位符相交的删除/替换作用于整颗。
+- 单字符占位使键盘原子性大半原生成立（caret 无内部位；Backspace/方向键/Shift 扩选原生即整颗）；鼠标点 chip 由 backdrop 命中 → 整颗 setSelectionRange。
+- 视觉投影 = label：backdrop 在占位符 offset 渲染 chip（textarea 字形不可见），invalid 走失效样式。
+- 剪贴板/持久化投影 = clipboardText：copy/cut 把选区内占位符展开；draft 持久化 mirror 写同一投影（chat store 里永远是普通文本，刷新 seed 语义 = 全选复制→重开→粘贴，chip 跨刷新降级为文本）。
+- 模型投影 = submit 时经 source `codec.serialize` 逐颗生成（归 submit attempt 的 signal 与 stale guard；owner 缺失/失败/取消则不发送，不降级为 `/name`）。
+
+### 跨插件输入改写：三个 scoped bail 事件
+
+契约声明在 ui-slash（依赖最底层），生产者经 `sctx.bail(sctx, ...)` 派发，唯一消费侧是 hub 建 shell 时挂在 sctx 上的三个 listener；返回 `true` ⟺ 机器过 phase + CAS 守卫并实际改写（发出事件 ≠ 修改成功，Space 是否 `preventDefault` 以返回值为准）：
+
+- `slash/input-begin-command` `{claim, span}`——菜单 pick / Space 裁决出的命令 claim 回填（SlashController 派发）。
+- `slash/input-insert-reference` `{reference, span}`——引用 chip 插入（SlashController 派发）。
+- `slash/input-consume-token` `{guard: span | bare-token}`——业务成功后消费命令 token（下游命令面派发）。
+
+不事件化的调用（registry 注册 → 显式调用 → await）：Input 自身的 draft/submit、Enter 异步裁决、reference serializer、异步 paste matcher。`@mode bail` 已入 JSDoc parser 与 cordis catalog 门禁（scripts/jsdoc.ts）。
+
+### slash 管线（ui-slash：root `SlashService` + per-session `SlashController`）
+
+对"命令"零知识的触发/菜单/pick 管线：
+
+- service 只有 source 注册表（`SlashSource{trigger: '/'|'@', name, candidates, onPick, matchSpace?, matchEnter?}`；(trigger,name) 唯一、注册序 = 组序 = 轮询序）与 `sessionOf(sctx)`。实现 match 钩子即参与空格/回车裁决的声明；管线按注册序轮询，首个非 undefined 应答胜出，无人认领落 default sink。matchSpace 同步（空格在击键中触发，只许热缓存）；matchEnter 异步（可 await 源自身预热，预热失败即 reject）。
+- controller 持有唯一权威 hit（含 span；菜单关闭后为 Space 保留）、per-session menu store、候选 fetch generation、键盘仲裁（combobox 模式：焦点始终在 textarea，↑↓/Enter/Escape 拦截且全程过 IME composition 守卫，唯一例外 Shift+Enter 无条件先行）、pick 编排（outcome → 自派 bail 事件）；每个 session scope 出生时对 source roster 做一次 `warm(projection)`，projection 在该 scope 内只有稳定的 sessionId，无 published/能力跃迁；scope disposer 拆除 controller。
+- 触发检测词边界（`user@host`、URL `/` 永不触发）、守卫分档（plain：`/` 到处 + `@` 行内 / claimed：`/` 抑制、`@` 活 / frozen：全无）为冻结纯核。
+
+### hub / facade：常驻外壳与严格 session 输入体
+
+- hub（trigger/decoration 注册表 + 发送编排）对 slash/command 服务是可选 `ctx.get()` 依赖：无 ui-slash/命令面时输入正常收发，优雅降级。
+- 每个实体 Session 只有一个 `SessionInputShell`（facade），随 session scope 创建和拆除；无 session 时不造 input machine。`ConversationRoot` 自身是 `session-maybe` 常驻外壳，持有 HeroShell、Workspace picker、composer stack 与 chain fallback 外框。
+- 无 session 时外壳渲染纯展示的 `DisabledInputBar`；`connectWorkspace` 返回 blank session 后，仅输入体换成严格 session 的 InputBar。这里允许 textarea 重建，`ConversationRoot`、Hero 与布局骨架保持；blank → engaging/active 仍是同一 session-bound InputBar，textarea 不因 phase 翻转而重建。
+- ConversationRoot 的 Hero 判据是 `sessionId === undefined || (composerPhase === 'blank' && (openState === 'open' || openState === 'loading'))`。首次 submit 同步进入 engaging，失败也保留 composer 与错误上下文，不退回 blank Hero；sidebar 的 blank 位只在 prompt 成功受理后翻 false。
+- 发送统一在 hub defaultSink：乐观清稿后只走 `session.prompt {mode:'queue'|'steer'}`；失败且 live draft 仍为空才回填，用户已经继续输入则不覆盖。不存在 Draft materialize 或 attach 事务。
+- blank Hero 改选 Workspace 时，外壳调用 `connectWorkspace`；目标 session 不同时把非空 draft 从当前 shell 搬到目标 shell，再 open 新 id，旧 blank session 留存但不再 current。
+- Notifier 双位契约：`dirty`（快照新鲜度，`ensureFresh` 拉取可清）与 `notifyPending`（通知欠账，只有 flush 清）各自独立——拉取不得吞推送，对象层推订阅者（watchTransaction）依赖这一保证。
+
+### 纯文本引用（决策 21）：text outcome 与 lexicon 装饰
+
+skill/@subagent 引用不走占位符 + occurrence 身份链——pick 直接把 `/name ` `@name ` 原文插进 draft，chip 视觉纯派生：
+
+- PickOutcome 增 `{text}` arm；新 scoped bail 事件 `slash/input-insert-text` `{text, span}`（与另三个同契约：draftRev CAS、返回 true ⟺ 实际改写）；facade.insertText 走 setDraft 拼接，机器零改动。
+- source 可选 `lexicon?(session)` 钩子：同步热快照名录，`undefined` = 数据未热——零装饰、永不触发 fetch（渲染路径保持同步无副作用）；controller 聚合为 `lexicon()` 公面。
+- `decorations.scanTextRefs`：词边界扫描 draft（行首/空白后的 `/name`、`@name`，`x/name` 永不命中）对照名录，命中即 `.textRef` mark（backdrop 纯 range 高亮，同 hlToken）；编辑破坏匹配形状下次扫描自然消失。
+- 发送即原文（不再 `<skill>` 序列化）；气泡侧 MessageItem 双形状装饰（legacy `<skill>` 标签 + 纯文本 token）。
+- 旧 occurrence/paste/serialize 链全部保留在盘未删（additive；删除另成将来一刀）。已知局限维持现状：粘贴/冷启动时 lexicon 未热不装饰，输 `/` 开一次菜单后才亮。
+
+### per-session 供数贡献与键盘私面
+
+- ui-conversation（hub 兼贡献者）经 `sessions.provide` 供 `'input'` hook（机器状态 + queue overlay）+ `inputActions` prop（`setDraft`/`submit`，稳定 void 回调）。
+- 公私分界：公共 provide 只放 React 语汇成员；键盘/DOM 命令面（track/arbitrate/space/undo/redo/paste/dismissPopup/bindMirror——同步返回值、disposer 语义）是 InputBar 独占，走 InputBar entry 自己的 inject 包内私递，不出插件边界。
+
+### 坑位体系
+
+`conversation` 本身是 session-maybe；其会话内容与 composer 输入坑位严格 session，Hero Workspace picker 保持 root。子坑均由 ui-conversation 的 conversation 注册声明：
+
+- `conversation.session`（single）——严格 session 的 header、view ring 与 chat store；session id 切换时重建。
+- `conversation.composer.bar`（single）——InputBar 本体的坑位：InputBar 是真 slot entry（自家坑自注册），composer chain fallback 的内容；不做 chain entry——chain 单选举会在 takeover 时卸载它，破坏 textarea DOM 存活。
+- `conversation.input.overlay`——输入卡内浮层锚点；注册者 inject 按 slot sessionId 解析各自 per-session controller。
+- `conversation.input.dock`——输入上方堆叠条（QueueDock 的队列只读列表落此），order 定序。
+- `conversation.composer.dock`——composer 上沿统计带。
+- `conversation.input.left` / `conversation.input.right`——工具行左右区。
+- `conversation.input.plan` / `conversation.input.model`（single）——工具行两具名控制位；bar 只传 `locked`（owner props），空到 owning 插件注册为止，无占位 fallback。
+- `conversation.hero.workspace`（root scope）——无 session / blank Hero 共用的 Workspace picker；pick 经 `connectWorkspace` 复用或创建目标 blank session，必要时搬运 draft 后切 current。
+
+### 测试纪律
+
+状态机全部行为由纯 JS 单测覆盖（事件序列进、断言状态与效果，零浏览器 DOM）；交互矩阵逐行投影测试。这一要求正是纯核 + 服务壳分层的成因。
+
+## Alternatives considered
+
+| 弃案 | 一行理由 |
+|---|---|
+| ActiveCommand 中间态 / registerMode 模式注册表 / 从 draft 推导命令态 | claim 由 pick 路径显式建立——无表、无推导 |
+| bindTarget/bindDraft 对象直连 | 反向耦合 + root 单例跨会话误配；scoped bail 事件保依赖倒置且路由结构性正确 |
+| 统一 slash/input-apply 或全事件化 | 三个独立 payload 覆盖跨插件改写；异步链路保持 registry 显式调用 |
+| contenteditable / 富文本树 | 兼容性差；textarea + U+FFFC + occurrence 表覆盖全部交互契约 |
+| draft 双持久化 {text, occurrences} | mirror 写剪贴板投影零新概念；chip 跨刷新降级可接受 |
+| 原生 textarea undo 栈 | 受控 + 程序化写入下不可靠；粘贴两段 undo 语义只能自管 |
+| InputBar 收 16 员 wiring 回调包 | 消费矩阵实证 11 员 InputBar 独占、1 员死成员；标准件通道让组件自取，键盘面包内私递 |
+| 空格裁决也认领即执行型命令 | 误触发防线：空格后整行是普通 prompt；不可逆副作用只留显式入口 |
+| 通用 tokenPattern 装饰机制 | 结构化 occurrence 记录取代模式扫描 |
+| 占位 select 常驻工具行 | 具名坑位空到注册为止；占位件与真实现冲突时是双真相源 |
+| 引用一律走 U+FFFC chip（决策 21 前旧线） | 纯文本 + 派生装饰零身份状态；原文即模型投影，undo/剪贴板免特判；chip 链保留给需要不可分原子性的场景 |
+
+## 后果
+
+- 一个常驻 conversation 外壳承接 no-session/blank/active：无 session → blank 只保证大框架 React identity，允许 disabled textarea 替换为严格 InputBar；同一 blank session → engaging/active 保持 InputBar 与 textarea。EmptyState 与受控 intent 链（`sessions.updateIntent`/`updatePendingPrompt`/`workspaces.sendSession`）随最后消费者一并删除。
+- 输入面对命令零知识 + 可选依赖：无命令包时纯输入可用；`@` 引用与 skill 引用免费复用同一菜单/pick 管线。代价是空格/回车裁决是逐 source 轮询协议，其应答语义（同步/异步、undefined 含义）为冻结契约。
+- 提交事务化（attempt seq + 漂移守卫）使晚到结果回灌、会话切换、concurrent 重放三类缺陷结构性不可能，由矩阵测试钉住。
+- 已知欠账：chip 跨刷新保真（可复用粘贴匹配）未立项；subagent 引用的模型表示待业务立项。

+# Agent Note: Web todo display — snapshot side-effect channel + two render surfaces
+
+Status: implemented
+
+English | [中文](2026-07-23-web-todo-display.zh.md)
+
+## Problem
+
+`todo_write` appends `todo/write` whole-list snapshots to the session log; the TUI renders a persistent plan panel (the automation-only ACP bridge deliberately omits todo presentation). The web client dropped the event entirely: the host mux stream already forwards every session event, but `todo/write` is not a surface type (it never folds into `ConversationSnapshot.nodes`), and no side-effect branch accumulated it — the browser had no consumption point and no display surface.
+
+## Decision
+
+Consume `todo/write` as a Session side effect, not a surface node, and render it on two surfaces matching the split the TUI already draws.
+
+### Side-effect channel, converging with window replay
+
+`applyEventSideEffects` gains a `todo/write` case (whole list, last write wins). Unlike partial/openCalls, `rebuildDerivedFromWindow` deliberately does NOT reset it: the value is session-level — taken from the tail history page's full-log projection — and an arbitrary window may not contain the latest write, so an older-page prepend keeps it and only an in-window or live write overwrites it. Every `installWindow` caller is a tail request (`doOpen`, its gap re-pull, `repairGap`; `loadOlder` prepends without it), which the host answers with the projection or omits it only when the full log holds no `todo/write` — so an absent field is the authoritative empty list and is assigned as such. That distinction matters on rollback: a live write whose host crashed before persisting leaves the log empty, and preserving the prior value instead would strand the rolled-back plan on screen indefinitely. `ConversationSnapshot.todos` is the read surface. This follows the event's own contract ("log-only UI state; never derived history"): surfacing each write as a conversation node would render superseded lists as if they were still standing.
+
+### TodoPanel: the durable list as a persistent strip
+
+The panel mounts through the `conversation.input.dock` slot (a plain registrant plugin, `todoDockEntry`, the QueueDock posture: `inject: ['slots', 'conversation']` as the load-order seam, `order: -1` above the queue rows), hidden while empty, collapsible to a header of title + `"<done>/<total> tasks · <n> in progress"` (no in-progress content hint when collapsed). Status glyphs are the figma todo set (green check ring / blue fading ring / dashed pending ring) on a tip-surface card (`--dsw-specific-tip`, 14px radius, `width: calc(100% - 88px)` / `max-width: 776px` centered; InputBar top pad 6px is the gap to the composer card). It reads `snapshot.todos` via the standard-kit `useSession` hook the dock entry receives — no store, no service, no ctx. The inner component stays props-complete and framework-free; the dock adapter is a one-line wrapper.
+
+### TodoRow: the per-call row through the keyed toolview slot
+
+The dedicated `todo_write` chat row is a plain registrant plugin (`todoToolview`, mounted from `apply`) that registers into the keyed `conversation.chat.toolview` slot via `ctx.slots.register` — the same seam and load-order posture as the bash sample (`inject: ['slots', 'conversation']`), but a product registration. The summary derives from call args (`N/M done · active item`); unparseable args fall back to the generic row summary; clicking opens the details column with the raw args. No `ToolEventView` is added for todo — presentation is client-owned, and the durable list renders from the session event, not the tool card.
+
+## Alternatives considered
+
+- **Fold todo writes into `nodes` as surface entries** — replayed windows would render every superseded list; the event is deliberately not a surface type.
+- **Hardcoding the panel inside `ConversationRoot`** — the original landing spot before the input-dock slot existed; the dock is the architecture's home for always-on strips above the composer, and a hardcode bypasses the slot registry's disposal and ordering.
+- **Details column for the panel** — the details slot is single-occupant and selection-driven, a different lifetime than an always-on strip.
+- **Host-computed view (a todo `ToolEventView`)** — presentation belongs to the client; the wire already carries the whole snapshot in the event payload.
+
+## Consequences
+
+Replay correctness is owned by one code path: any future change to window rebuild keeps todos consistent for free, and the fixture (fx-alpha turn 65) plus the assembled keyless snapshot (`apps/web/tests/todo-display.snapshot.ts`) pin the full chain (row summary and state, dock panel content, collapse round-trip) over the built client graph. `todos` is a required `ConversationSnapshot` field, so scripted fakes in specs must carry it. The TUI panel is untouched (the automation-only ACP bridge deliberately omits todo presentation); the web surfaces render the same event, adding one wire field and no new event type. That field is how cold-load reconstruction stays host-backed: the tail history page carries `todos` — the full-log latest `todo/write`, computed independently of the page window (the same backscan posture the view pairing uses) — so a reopened session restores the plan even when the last write precedes the window; that value survives an older-page prepend, is overwritten by any later write, and resets to empty when a tail response carries no projection.

+# Agent Note: Web todo 展示——快照副作用通道 + 两个渲染面
+
+Status: implemented
+
+[English](2026-07-23-web-todo-display.md) | 中文
+
+## Problem
+
+`todo_write` 把 `todo/write` 的整份列表快照追加进会话日志；TUI 渲染一块常驻的 plan 面板（自动化专用的 ACP 桥接刻意不做 todo 呈现）。Web 客户端把这个事件整个丢弃了：host mux 流本已转发每一个会话事件，但 `todo/write` 不是 surface 类型（它从不 fold 进 `ConversationSnapshot.nodes`），也没有任何副作用分支累积它——浏览器既无消费点，也无展示面。
+
+## Decision
+
+把 `todo/write` 当作 Session 副作用消费，而非 surface 节点，并在两个面上渲染它，这两个面正对应 TUI 已经绘制的那套划分。
+
+### 副作用通道，与窗口回放收敛
+
+`applyEventSideEffects` 新增一个 `todo/write` 分支（整份列表，后写覆盖先写）。与 partial/openCalls 不同，`rebuildDerivedFromWindow` 刻意不重置它：该值是会话级的——取自尾页 history 携带的全量 log 投影——而任意窗口未必包含最近一次写入，因此往前翻页保留它，只有窗口内或实时的写入才会覆盖。`installWindow` 的每个调用方都是尾页请求（`doOpen`、其补洞重拉、`repairGap`；`loadOlder` 只往前拼接、不走它），而 host 对尾页请求要么带上投影、要么仅在全量 log 没有任何 `todo/write` 时省略——因此字段缺失就是权威的空列表，直接照此赋值。这个区分在回滚场景上要紧：实时写入若在 host 持久化前崩溃，log 里就是空的，此时保留旧值会让已回滚的计划永远留在屏幕上。`ConversationSnapshot.todos` 是读取面。这遵循事件自身的契约（「仅日志 UI 状态，绝非派生历史」）：把每次写入作为对话节点呈现，会让已被取代的列表看起来仍然有效。
+
+### TodoPanel：长驻列表作为一条常驻横条
+
+面板经 `conversation.input.dock` slot 挂载（普通注册者插件 `todoDockEntry`，QueueDock 同款姿势：`inject: ['slots', 'conversation']` 载序 seam，`order: -1` 排在队列条上方），空列表时隐藏，可折叠为标题加 `"<已完成>/<总数> tasks · <n> in progress"` 的表头（折叠态不再附带进行中条目正文）。状态图标为 figma todo 套件（绿色勾选环／蓝色渐隐环／虚线未开始环），卡片使用 tip 表面（`--dsw-specific-tip`、14px 圆角、`width: calc(100% - 88px)`／`max-width: 776px` 居中；InputBar 顶部 6px 内边距是到输入卡的间距）。它经 dock entry 收到的标准件 `useSession` hook 读取 `snapshot.todos`——无 store、无 service、无 ctx。内部组件保持 props 完备且框架无关；dock 适配件只是一行包装。
+
+### TodoRow：经 keyed toolview slot 的逐调用行
+
+专用的 `todo_write` 对话行是一个普通注册者插件（`todoToolview`，由 `apply` 挂载），经 `ctx.slots.register` 注册进 keyed 的 `conversation.chat.toolview` slot——与 bash 样例同一接缝、同一载序姿态（`inject: ['slots', 'conversation']`），但属产品级注册。摘要由调用 args 推导（`N/M done · active item`）；无法解析的 args 回退到通用行摘要；点击会以原始 args 打开 details 列。todo 不新增任何 `ToolEventView`——呈现归客户端所有，常驻列表从会话事件渲染，而非工具卡。
+
+## Alternatives considered
+
+- **把 todo 写入作为 surface 条目折叠进 `nodes`**——回放的窗口会渲染每一份已被取代的列表；该事件被刻意设计成非 surface 类型。
+- **面板硬编码进 `ConversationRoot`**——input-dock slot 出现之前的原始落点；dock 是本架构给"composer 上方常开横条"安排的家，硬编码绕开了 slot 注册表的 disposal 与定序。
+- **面板放进 details 列**——details slot 单占用且由选中驱动，生命周期不同于一条常开横条。
+- **host 计算的视图（一个 todo `ToolEventView`）**——呈现属于客户端；协议已在事件载荷里携带整份快照。
+
+## Consequences
+
+回放正确性由一条代码路径掌管：未来对窗口重建的任何改动都免费保持 todos 一致；fx-alpha 第 65 轮的 fixture（测试前置数据）加 assembled keyless snapshot（`apps/web/tests/todo-display.snapshot.ts`）在构建产物客户端全图上钉住整条链（行摘要与状态、dock 面板内容、折叠往返）。`todos` 是 `ConversationSnapshot` 的必填字段，所以 spec 里脚本化的 fake 必须带上它。TUI 面板未受改动（自动化专用的 ACP 桥接刻意不做 todo 呈现）；Web 各面渲染同一个事件，只新增一个协议字段，不新增事件类型。冷加载重建正是靠这个字段由 host 兜底：history 尾页附带 `todos`——全量 log 上最新一次 `todo/write` 的投影，独立于分页窗口计算（与 view 配对同一种 backscan 姿势）——因此重开会话时即使最后一次写入落在窗口之前，计划也照常恢复；该值跨往前翻页保留，之后的任何写入照常覆盖，而尾页响应不带投影时复位为空。

+English | [中文](2026-07-27-user-message-icon-actions.zh.md)
+
+## Problem
+
+The chat user bubble had no under-bubble action chrome. The Harness design (figma `User_Bubble/message_container`) shows three IconActions — copy, branch in new chat, and edit — right-aligned under the bubble, matching the product action-bar pattern used elsewhere.
+
+## Decision
+
+`MessageItem` owns the actions for `kind: 'user'` only. Layout is a column (`align-items: flex-end`, 6px gap): bubble, then a 28px action row with 10px gaps and 28px circular icon buttons (`IconCopyOutline16`, `IconBranchOutline16`, `IconEditOutline16`). Tooltips carry Chinese labels. Actions stay visible by default; `@media (hover: hover)` hides them until the row is hovered or focus-within, so touch / `hover: none` devices keep discoverable controls (opacity alone still hit-tests).
+
+Copy writes the bubble's joined text blocks to the clipboard (`navigator.clipboard.writeText`, with an `execCommand` fallback). Branch and edit are present chrome with no handlers yet — they reserve the design seats without inventing session-fork or edit-resubmit behavior.
+
+Steering bubbles keep the badge-only form and do not show these actions.
+
+## Alternatives considered
+
+**Wire branch/edit to real session fork and draft-edit now.** Rejected for this change: those product flows are not specified; shipping inert buttons matches the requested scope and avoids half-built mutation paths.
+
+**Always hide with `opacity: 0` outside hover.** Rejected for touch: without `@media (hover: hover)`, idle opacity still hit-tests while looking empty. Hover-capable pointers keep the fade; others keep the actions visible.

+# Agent Note: Workspace Registration Deletion
+
+Status: implemented
+
+English | [中文](2026-07-27-workspace-registration-deletion.zh.md)
+
+## Problem
+
+A Workspace registers an existing code directory so the GUI can name it and order its Sessions. That record has no reliable provenance proving that Harness created or owns the directory, and the Session log is an independent persistence object. Treating the row's Delete action as recursive source deletion or Session deletion would destroy data outside the record's ownership boundary.
+
+The existing visual-only menu row also left deletion semantics undefined across durable order, the Workspace table, Host streams, concurrent browser tabs, reconnect baselines, and a list request racing the mutation.
+
+## Decision
+
+`ctx.workspace.delete(id)` deletes only the Workspace registration: its id leaves durable `workspaceIds`, its `workspaces` table row and entity-cache entry disappear, and its ordered `sessionIds` account disappears with that row. It never calls filesystem removal or `SessionPersistence`; the directory, every user file, every live Session, and every persisted Session log remain. Because sidebar grouping is the complement of all surviving Workspace accounts, those Sessions immediately appear under Ungrouped, including the current Session.
+
+Unknown ids return `false` at the domain seam. `workspace.delete({ workspaceId })` maps that distinction to `workspace-not-found`; success returns `{ deleted: true }`. `workspace.list` remains the reconnect baseline.
+
+## Durable commit and publication
+
+Registry operations serialize create and delete. Deletion first writes the Workspace order without the id, then removes the entity from the cache, then deletes the table row. The table deletion is the notification commit point: the package invariant accepts it only after the cache stopped publishing the entity, and the Host emits `host/workspace-removed` only from that committed deletion. A table-write failure restores the cache and prior durable order; no removal frame is published.
+
+The Host stream keeps its committed-id set through the preceding global-order write and removes the id only on the table deletion. Create rollback therefore emits no false removal, while every connected tab receives exactly the id needed to delete its projection.
+
+Create and delete write a durable `pendingMutation` before their record/order pair can diverge. Startup completes only the named create or delete and clears the marker; it never infers crash provenance from an orphan row alone. Unmarked order/table divergence therefore retains the registry's fail-loud corruption behavior. A deletion whose table write committed but marker cleanup failed still reports success—the requested state and removal frame are already committed—and the next startup clears that marker idempotently.
+
+## Client convergence
+
+`WorkspaceManager` treats both `host/workspace-changed` and `host/workspace-removed` as ordered deltas replayed over an in-flight `workspace.list` response. A successful unary delete removes the row immediately instead of waiting for its own stream echo. Removal is idempotent, and a process-local tombstone rejects late changed frames or stale baseline rows for the never-reused Workspace id. A reconnect still refreshes from `workspace.list`; Session state is never pruned by a Workspace delta.
+
+The delete confirmation remains pending until the React Workspace projection has committed the removed id, so the next create gesture cannot observe one stale list frame. During create, duplicate-name validation is suppressed while the request is pending because the committed `host/workspace-changed` frame may publish the newly created Workspace before its unary response; after failure returns the form to editing, validation uses the latest list again.
+
+## Confirmation interaction
+
+The existing Workspace row menu opens a shared `Modal` before deletion. The text states all three consequences: the Workspace leaves the list, the folder and session logs remain, and its Sessions appear under Ungrouped. While the request is pending, the confirm and Cancel controls are disabled, duplicate confirmation is ignored, and Escape or Close cannot dismiss the operation. Failure keeps the Modal open with the error; Cancel, Escape, and Close before submission never delete.
+
+The menu, Modal, and buttons retain their existing structure and design tokens. Session deletion remains visual-only and outside this decision.
+
+## Alternatives considered
+
+**Cascade-delete Sessions.** Rejected because Workspace registration does not own Session persistence and the product requirement is to preserve histories under Ungrouped. Session deletion needs its own lifecycle, running checks, descendant semantics, and explicit UI.
+
+**Move the folder to Trash.** Rejected because the record cannot prove directory ownership. A future destructive filesystem action must be separately named, separately confirmed, and enforce explicit safety boundaries.
+
+**Delete the table row and repair order later.** Rejected because a crash or write failure would leave an initialized registry whose order and table disagree. The registry updates both under one serialized operation and restores the prior order on table failure.
+
+**Delete every unreferenced row at startup.** Rejected because the same shape can come from unexplained order corruption; silently discarding it could lose Workspace metadata and Session accounting. Recovery requires the explicit pending marker written by the owning mutation.
+
+**Refetch both lists after success.** Rejected because the committed removal frame plus immediate unary echo is sufficient, preserves the current Session object, and avoids turning a local mutation into two list requests. Reconnect baselines remain the repair path.
+
+## Verification
+
+Workspace package tests pin successful metadata-only deletion, same-path re-registration, unknown-id idempotence, table-failure rollback, explicit-marker restart recovery, unexplained-corruption rejection, and cache/table invariant behavior. Apiproxy and carrier tests pin the schema, handler, `workspace-not-found`, retained Session/folder, fresh-id re-registration, and committed `host/workspace-removed` frame. Client tests pin unary direct echo, duplicate removal, late changed frames, and deletion racing an in-flight baseline. Component tests pin confirmation, projection-settled closing, pending-state duplicate suppression, success-frame-before-unary ordering, failure, Cancel, Escape, and Close. The browser scenario observes every transient alert, slot error, console error, and page error while reusing a deleted title for a different directory.

+The assembled keyless Web scenario registers an existing temporary project directory, accounts a persisted Session, makes that Session current, confirms deletion in Chromium, and verifies the Workspace group disappears while Ungrouped retains the current Session. It checks the user file and JSONL log before and after deletion and repeats the UI, directory, and log assertions after reload.
+
+## Consequences
+
+Deleting a Workspace is intentionally reversible by registering the same directory again with a fresh id, although its prior manual Session order is gone; re-registration does not automatically re-adopt existing Sessions after bootstrap. The operation gives up a one-click cleanup of Session histories or source directories in exchange for a deletion boundary that matches what the record actually owns.

+# Agent Note（agent 决策记录）：删除 Workspace 注册记录
+
+Status: implemented
+
+[English](2026-07-27-workspace-registration-deletion.md) | 中文
+
+## Problem
+
+Workspace 注册已有代码目录，使 GUI 能够为目录命名，并对其会话排序。该记录没有可靠的来源信息来证明 Harness 创建或拥有该目录，会话日志也是独立的持久化对象。若将行内 Delete 操作视为递归删除源码或删除会话，就会破坏该记录所有权边界之外的数据。
+
+现有菜单行仅提供视觉效果，因此持久顺序、Workspace 表、Host 流、并发浏览器标签页、重连基线，以及列表请求与变更并发时的删除语义也没有定义。
+
+## Decision
+
+`ctx.workspace.delete(id)` 只删除 Workspace 注册记录：其 id 会从持久 `workspaceIds` 中移除，`workspaces` 表行与实体缓存条目会消失，有序 `sessionIds` 账本也随该行一并消失。它绝不调用文件系统移除操作或 `SessionPersistence`；目录、所有用户文件、所有实时会话和所有持久化会话日志都会保留。侧边栏分组是所有存续 Workspace 账本的补集，因此这些会话（包括当前会话）会立即出现在 Ungrouped 下。
+
+未知 id 在 domain seam 返回 `false`。`workspace.delete({ workspaceId })` 将该结果映射为 `workspace-not-found`；成功时返回 `{ deleted: true }`。`workspace.list` 仍是重连基线。
+
+## 持久提交与发布
+
+注册表操作会串行执行创建与删除。删除时先写入移除该 id 后的 Workspace 顺序，再从缓存中移除实体，最后删除表行。表删除是通知提交点：只有缓存停止发布该实体后，包不变量才接受该删除；Host 也只根据这次已提交的删除发出 `host/workspace-removed`。表写入失败时，系统会恢复缓存和此前的持久顺序，且不会发布移除帧。
+
+Host 流在前一笔全局顺序写入期间继续保留其已提交 id 集合，只在删除表行时移除该 id。因此，创建回滚不会发出错误的移除帧，而每个已连接标签页都能收到从自身投影中删除该记录所需的准确 id。
+
+Create 与 delete 会在记录／顺序对可能分叉之前写入持久 `pendingMutation`。启动时只补全其中明确命名的 create 或 delete，并清除该标记；系统绝不会仅凭孤立表行的形状推断崩溃来源。因此，没有标记的顺序／表分叉仍会保持注册表原有的损坏直接失败语义。如果删除的表写入已经提交、但标记清理失败，操作仍会报告成功——请求状态和移除帧都已经提交——下一次启动会以幂等方式清除该标记。
+
+## 客户端收敛
+
+`WorkspaceManager` 将 `host/workspace-changed` 与 `host/workspace-removed` 都视为有序增量，并在进行中的 `workspace.list` 响应之上回放。成功的一元删除会立即移除行，无需等待本次操作自己的流回显。移除操作具有幂等性；由于 Workspace id 永不复用，进程本地删除标记会拒绝延迟到达的 changed 帧或陈旧基线行。重连仍从 `workspace.list` 刷新；Workspace 增量绝不会剪除会话状态。
+
+删除确认框会保持待处理，直到 React Workspace 投影已经提交目标 id 的移除，因此下一次创建操作不会读到一帧陈旧列表。创建请求进行中会暂停重复名称校验，因为已提交的 `host/workspace-changed` 帧可能先于一元响应发布刚创建的 Workspace；如果请求失败并让表单回到可编辑状态，系统会重新使用最新列表执行校验。
+
+## 确认交互
+
+现有 Workspace 行菜单会在删除前打开共享 `Modal`。文案明确说明三项后果：Workspace 会从列表中移除，文件夹和会话日志会保留，相关会话会出现在 Ungrouped 下。请求待处理期间，确认与 Cancel 控件均被禁用，重复确认会被忽略，Escape 或 Close 也无法关闭此次操作。失败时 `Modal` 保持打开并显示错误；提交前使用 Cancel、Escape 或 Close 绝不会触发删除。
+
+菜单、`Modal` 和按钮保留现有结构与设计 token。会话删除仍仅提供视觉效果，不在本决策范围内。
+
+## Alternatives considered
+
+**级联删除会话。** 不予采纳，因为 Workspace 注册记录不拥有会话持久化，且产品需求是将历史记录保留在 Ungrouped 下。会话删除需要自己的生命周期、运行状态检查、后代对象的处理语义和明确 UI。
+
+**将文件夹移到废纸篓。** 不予采纳，因为该记录无法证明目录所有权。未来的破坏性文件系统操作必须使用单独名称、单独确认，并实施明确的安全边界。
+
+**先删除表行，之后再修复顺序。** 不予采纳，因为崩溃或写入失败会使已初始化注册表的顺序与表不一致。注册表会在同一串行操作内更新二者，并在表操作失败时恢复此前顺序。
+
+**启动时删除所有未引用表行。** 不予采纳，因为来源不明的顺序损坏也会呈现相同形状；静默丢弃可能损失 Workspace 元数据和 Session 账本。恢复必须依赖拥有该变更的操作预先写入的明确待处理标记。
+
+**成功后重新拉取两个列表。** 不予采纳，因为已提交的移除帧与即时一元回显已足够，既能保留当前会话对象，也避免将局部变更扩大为两次列表请求。重连基线仍是修复路径。
+
+## Verification
+
+Workspace 包测试固定了仅删除元数据的成功路径、同路径重新注册、未知 id 的幂等行为、表操作失败回滚、明确标记的重启恢复、来源不明损坏的拒绝，以及缓存／表不变量行为。Apiproxy 与载体测试固定了 schema、处理器、`workspace-not-found`、保留会话／文件夹、使用新 id 重新注册，以及已提交的 `host/workspace-removed` 帧。客户端测试固定了一元直接回显、重复移除、延迟到达的 changed 帧，以及删除与进行中基线并发的行为。组件测试固定了确认交互、投影稳定后关闭、待处理状态下抑制重复提交、成功帧先于一元响应、失败、Cancel、Escape 与 Close。浏览器场景会在为不同目录复用已删除名称时，观测每一次瞬时 alert、slot error、console error 与 page error。
+
+组装后的无密钥 Web 场景会注册一个已有临时项目目录，将持久化会话计入账本，把该会话设为当前会话，在 Chromium 中确认删除，并验证 Workspace 分组消失，而 Ungrouped 保留当前会话。该场景在删除前后检查用户文件和 JSONL 日志，并在刷新后重复验证 UI、目录与日志。
+
+## Consequences
+
+删除 Workspace 后仍可使用新 id 重新注册同一目录，因此该操作有意设计为可逆；但此前的手动会话顺序会丢失，重新注册后，系统也不会在 bootstrap 结束后自动重新收编现有会话。该操作放弃一键清理会话历史或源码目录，以换取与记录实际所有权一致的删除边界。

 ## Decision

 - **Paired sibling files with equal authority.** A documentation pair is three sibling files: English `foo.md`, Chinese `foo.zh.md`, and a consistency record `foo.i18n.yaml`. Neither language is canonical — a document may be authored and reviewed Chinese-first and translated to English afterwards, or the reverse; what binds the pair is that both sides must say the same thing, and pairs merge whole (both languages plus the record, never one alone). Policy: [docs/i18n/README.md](../../../../docs/i18n/README.md); translation rules: [docs/i18n/translation-rules.md](../../../../docs/i18n/translation-rules.md); terminology source of truth: [docs/i18n/terminology.md](../../../../docs/i18n/terminology.md).
- **A sidecar record of both blob hashes makes consistency checkable.** `foo.i18n.yaml` holds the full git blob hash of each side as of the last confirmed-consistent state. An edit to either side without re-confirming the pair is then mechanically detectable as a pure content comparison — no history lookup — and the hashes are computable for files edited in the same PR, which a commit-hash record is not. Re-recording (`verify-translation-pairing --write`) produces a reviewable yaml diff: confirming consistency is an explicit, visible act in the PR.
+- **A sidecar record of both blob hashes makes consistency checkable.** `foo.i18n.yaml` holds the full git blob hash of each side as of the last confirmed-consistent state.

 - **`verify-translation-pairing` joins `doc-sync`.** The gate ([scripts/verify-translation-pairing.ts](../../../../scripts/verify-translation-pairing.ts)) enforces: every discovered, non-excluded source has a complete pair; every existing pair is complete (all three files) and consistent (both hashes match, switcher links both ways, structural signatures identical); and excluded generated, instruction, or bilingual-by-construction files stay unpaired. [scripts/translation-pairing.manifest.json](../../../../scripts/translation-pairing.manifest.json) contains only explicit exclusions, so no requirement can bypass discovery and receive a weaker check. Source-oriented code gates consume a `.zh.md` fence sequence as a derivative only when its unsuffixed sibling has the same tracked fences in the same order with byte-identical bodies; an incomplete, reordered, reclassified, or changed sequence stays independent, so the owning code gate or pairing gate reports the mismatch.
 - **One corpus-wide requirement.** Every document in scope requires a complete pair from creation; the policy has no per-file rollout state, date cutoff, or README-specific class. README discovery covers every case-insensitive README basename outside vendored, dependency, and ignored build-output trees, including future top-level directories. A site-published pair uses `pairedPages()` so the root locale projects `.zh.md` and `/en/` projects `.md`; creating a counterpart alone does not publish it.
 - **Pairing records are metadata, not Cordis Loader configuration.** Cordis configuration discovery accepts actual `.cordis.yml` and `.cordis.yaml` files while excluding `*.i18n.yaml`, even when the document name contains `cordis`. This preserves validation of executable Loader entries without parsing translation hashes as configuration.

Pull requests run consolidated Linux and Windows jobs plus the Node compatibility and Python contracts on standard GitHub-hosted capacity. A push to `master` skips those jobs and runs four explicit references: `serial / linux`, `serial / macos`, and `serial / windows` on standard hosted runners, plus `serial / linux (self-hosted standby)` on the in-house `vm-backup` pool — the hot-standby drill that continuously re-proves the failover target described in the [failover runbook](2026-07-26-ci-failover-runbook.md).

The reference jobs may run beside one another, but each host's repository gates are serial and complete. Linux installs bubblewrap before replaying snapshots, and Windows enables Developer Mode before installing the symlinked workspace.

 Platform ownership remains explicit inside that complete aggregate. `pty-local` supports Linux and macOS and therefore owns its unit and per-file coverage contract on POSIX rather than loading a backend that rejects `win32`; the Windows run still executes every portable package. Portable fixtures derive native paths through `node:path`, compare canonical identities with the same native realpath implementation as production, and use filenames legal on every host. ACP snapshot runs also pass both JavaScript and native realpath spellings of their generated cwd to the normalizer, which replaces aliases longest-first so Windows short and long paths cannot churn shared fixtures.

 The macOS reference runs the ordinary Vitest project in forked processes. Node 24 on macOS arm64 has aborted in its CJS lexer from a worker thread; the process boundary contains that external runtime failure without removing any test from the aggregate, while Linux and Windows retain the lower-overhead thread pool. Repository-owned races are fixed at their observation boundaries: dev bundle polling stages each candidate table, graph, and watch-baseline map before publishing a rescan, and a missing bundle remains dirty until a successful content hash. PTY readiness retains a prompt candidate while polling checks foreground ownership; the ordinary silence bound covers inherited markers from interactive children. Real PTY fixtures assemble synchronization tokens at runtime so the interactive shell's input echo cannot satisfy a child-readiness wait. The live-link package-manager e2e preserves the workflow-prepared Corepack home and pnpm metadata/store caches while isolating the other managers' mutable caches, so it does not discard reusable package-manager state before the install.

 macOS 参考流程使用 fork 进程运行常规 Vitest 项目。macOS arm64 上的 Node 24 曾在工作线程中执行 CJS 词法分析器时异常终止；进程边界能够隔离这一外部运行时故障，且无需从聚合流程中删除任何测试，而 Linux 与 Windows 仍使用开销更低的线程池。仓库自身引入的竞态均在相应的观测边界修复：开发构建产物的轮询逻辑每次发布重新扫描结果前，都会先暂存候选表、候选图和候选监视基线映射；构建产物缺失后会一直保持脏状态，直到成功计算内容哈希。PTY 就绪检测会在轮询检查前台进程组归属期间保留提示符候选项；常规静默时限也适用于交互式子进程继承提示符标记的情况。真实 PTY fixture 会在运行时拼接同步标记，使就绪等待逻辑不会把交互式 shell 的输入回显误判为子进程已就绪。实时链接场景下的包管理器 e2e 会保留由工作流预先准备的 Corepack 主目录、pnpm 元数据缓存和 store 缓存，同时隔离其他包管理器的可变缓存，因此不会在安装前丢弃可复用的包管理器状态。

It is a hot-standby drill, not a required check: each run re-proves that the persistent VM can execute the complete unsharded aggregate. The actual switch is pre-wired: the three required Linux jobs resolve their pool through the writer-manageable `DSH_CI_FAILOVER` repository variable, so an outage response is setting one variable and re-running — no merge, which would be deadlocked behind the failing checks themselves ([runbook](2026-07-26-ci-failover-runbook.md)). The standby lane is push-triggered, so it always executes the base branch's workflow definition.

 ## Alternatives considered

 **Keep the three coarse primary Linux lanes.** The core, CPU, and production-site jobs met the latency targets, but they paid three setup waves and left primary Node work sharded after larger runners were available.

+# Agent Note: Briefed minimal translation updates
+
+Status: implemented

+
+## Problem
+
+The [bilingual pairing contract](2026-07-02-bilingual-docs-and-pairing-gate.md) already prescribed minimal counterpart updates — diff the edited side against its last-confirmed state, patch the counterpart, never re-translate — but the committed workflow made every update pay whole-document overheads. The translating subagent loaded the full guidance corpus (skill, pairing contract, translation rules, the 192-line terminology table, style samples, prose standard) before touching a two-line diff; it re-derived the last-confirmed diff by hand through `git cat-file`; and each iteration re-ran the corpus-wide pairing gate, which parses every pair in the tree to validate one. A small English prose edit routinely cost tens of times its proportional share of tokens and minutes, which taxes exactly the behavior the contract wants — bringing the counterpart along in the same PR.
+
+## Decision
+
+Pair updates run on a generated briefing instead of the guidance corpus; only new pairs still run the whole-document workflow, which is unchanged.
+
+- **`pnpm run gen-translation-brief [--apply] [pair...]`** ([scripts/gen-translation-brief.ts](../../../../scripts/gen-translation-brief.ts), assembly in [scripts/translation-brief.ts](../../../../scripts/translation-brief.ts)) prints, per out-of-sync pair, the authored side's diff from its recorded last-confirmed blob to the working tree plus the change mapped at the narrowest safely aligned granularity, deterministically widening on mapping failure: a change confined to the pair's byte-identical code fences is computed outright (`--apply` splices it into the counterpart and validates the result against the pairing gate's structural signature before writing); otherwise changed Markdown units (headings, paragraphs, table rows, list items, code fences, block quotes, HTML blocks, thematic breaks, link definitions — matched by container-scoped kind sequences) each carry their last-confirmed source, current source, and current counterpart text with line numbers; units that do not align fall back to depth-matched heading sections; and when sections do not align either, or both sides drifted, the briefing says so and withholds the mapping instead of guessing. Terminology rows are matched against the changed spans only (word-boundary English matching with plural inflections), and for Chinese targets the briefing tracks each relevant term's document-wide first occurrence — when an edit moves it, the vacated and receiving spans join the briefing with an explanatory note, since the 首次出现 annotation must move with it. The unit mapping, code splice, and first-occurrence mechanics adopt the planner design from the [incremental prompt-pipeline work](https://github.com/deepseek-harness/deepseek-harness/pull/684), whose provider-backed bake-off independently validated the same scope ladder for the automated pipeline. The briefing is the translator's whole working set; the full sources of truth remain the escalation path for decisions the briefing cannot answer.
+- **The update path in [dsh-translate-docs](../../../skills/dsh-translate-docs/SKILL.md)** consumes the briefing: mechanical (code-fence-only) changes are applied with `--apply`, no subagent; prose diffs go to a subagent whose prompt is the briefing, not the corpus; verification is clause-by-clause on the changed spans, not the whole document.
+- **The pairing gate takes pair arguments.** `verify-translation-pairing [pair...]` checks just the named pairs (any of a pair's three files, or the bare stem, names it); the corpus-wide sweep remains the no-argument form that `doc-sync` and CI run. `--write` now requires naming the confirmed pairs — bare `--write` refuses, and re-recording everything is an explicit `--write --all` — because the old bare form silently blessed every drifted pair in the tree, including ones the caller never looked at, and a prose-only drift would then stay green forever. Each record's comment names its own scoped command.
+
+## Benchmark
+
+The decision followed a controlled replay of ten real pair updates from this repo's history (July 2026; 1-64 changed English lines each, READMEs, RFCs, Agent Notes, and user docs). Each example was reconstructed in a scratch repo at its true last-confirmed state with the English edit uncommitted, then run through competing workflows with fresh subagents: the status-quo corpus-loading path, the briefed path, a no-guidance control, whole-document re-translation, the briefed path on a small model, and a three-pairs-per-agent batch. Outputs were gated mechanically and scored blind by judges who also received the real historical update and the untouched stale counterpart as controls.
+
+- The briefed path matched the status-quo path on judged faithfulness, preservation, and fluency — both at or above the real historical updates — while spending roughly a third of the tokens and wall clock on the stall-free examples (medians across all ten: 276k vs 595k relative token-cost units, 14 vs 32 turns).
+- Re-translation was confirmed harmful, not merely wasteful: judged preservation collapsed (4.4/10 vs 9.8) because it discards reviewed phrasing, it drifted established terminology the update arms kept (the counterpart's own text carries the renderings), and it was the most expensive arm.
+- The no-guidance control held quality too — the binding context for an update is the diff plus the counterpart's own reviewed text, not the corpus — but the briefing buys a fixed working set, inline terminology, and the both-sides-drifted warning at negligible cost over it.
+- On the briefing, a small model performed at parity with the large one, so the update path no longer assumes a frontier translator.
+- Batching three pairs into one subagent showed no reliable saving over three briefed runs and couples unrelated failures; it was rejected.
+
+A second head-to-head replay on the same ten examples compared this note's shipped briefing against its earlier section-only form (no unit tier, no computed mechanical path, counterpart-only context, no first-occurrence tracking). Prose quality and cost were at parity — pairwise blind verdicts split with only stylistic margins — and the shipped form won on two objective outcomes: the two code-fence-only examples were completed byte-identical to the human-reviewed historical updates in under a second with no model tokens, and on the example whose edit moved a term's document-wide first occurrence, the shipped briefing's flagged move reproduced the human-reviewed gloss relocation while the section-only form left a 首次出现 violation for review to catch.
+
+## Alternatives considered
+
+- **Keep the workflow, just scope the gate** — the gate scan was the smaller cost; the corpus loads and archaeology dominated. Scoping alone would have left the ~3x overhead in place.
+- **Whole-document re-translation as the update path** (what a naive pipeline does) — rejected on benchmark evidence: preservation collapse, terminology drift, highest cost. The contract's minimal-update rule survives with data behind it.
+- **Batching several pairs per subagent** — rejected: no measured saving (briefings already deduplicate the fixed content), and one stalled or confused pair holds the others hostage.
+- **Per-paragraph translation-memory records in the sidecar** (segment hashes instead of whole-file hashes) — rejected: paragraph boundaries may legitimately differ across the pair, either side can be authored first, and the records would bloat and conflict in merges. Span mapping computed on demand from the existing whole-file hashes recovers the same alignment when it is trustworthy and says so when it is not.
+- **An update mode in the automated prompt pipeline (prompt-v5)** — deferred, not designed here: nothing drives [scripts/translation-prompt.ts](../../../../scripts/translation-prompt.ts) today, and the agent path was the live cost center. The pipeline keeps its whole-document v4 contract until it has a consumer.
+
+## Consequences
+
+- A small prose edit's counterpart update now costs a briefing generation plus one small focused task — no corpus reads, no archaeology, no corpus-wide scans inside the loop — and the same PR obligation holds; the cheap path and the correct path point the same way.
+- The briefing generator is a second consumer of the consistency records: recorded blob hashes now also drive diff recovery and section mapping, strengthening the incentive to keep records honest.
+- `--write` without arguments no longer works; muscle-memory callers must name pairs or pass `--all`. That is the point — the bulk bless is now a visible, deliberate act.
+- Scoped checks mean an update loop can be green while an unrelated pair elsewhere is red; the corpus-wide check in `doc-sync`/CI still owns the tree-level invariant.
+- Span mapping trusts an alignment only when the kind sequences match across the last-confirmed source, current source, and current counterpart; a mapping failure widens deterministically (units → sections → whole document) rather than guessing, so a restructured document gets an explicit "locate the regions yourself" briefing, never a wrong map.
+- A first-occurrence move can enlarge a briefing beyond the directly changed spans; that cost is an explicit consequence of the 首次出现 contract, not an alignment heuristic.
+
+## Testing
+
+[scripts/translation-brief.spec.ts](../../../../scripts/translation-brief.spec.ts) pins unit and section span extraction (container-scoped kinds, depth-only section alignment so translated heading text still maps, preamble), alignment and changed-index detection, the mechanical code splice and each of its refusal conditions, terminology row matching in both directions with word-boundary and plural-inflection discipline, first-occurrence movement tracking, fence escalation, and the rendered briefing's contract (unit bundles with three-way context, mechanical/sections/document scopes, per-direction digests, scoped finish commands). [scripts/translation-pairing.spec.ts](../../../../scripts/translation-pairing.spec.ts) pins argument normalization (any pair file or bare stem to the anchor) and the CLI matrix: scoped check, bare `--write` refusal, `--write <pair>`, `--write --all`, `--list` exclusivity, unknown flags.

+## 问题
+
+[双语配对契约](2026-07-02-bilingual-docs-and-pairing-gate.md)早已规定对侧文件按最小幅度更新：把被改的一侧与其上次确认状态做 diff，据此修补对侧文件，绝不整篇重译；但仓库内置的工作流让每次更新都付出整篇文档级别的开销。负责翻译的 subagent 在动手处理一个两行的 diff 之前，要先加载完整的指导语料（guidance corpus），即 skill（技能）、配对契约、翻译规则、192 行的术语表、语体样例与行文标准；要通过 `git cat-file` 手工重新推导上次确认状态以来的 diff；每轮迭代还要重跑全语料配对门禁，而该门禁为校验一个配对要解析整棵树里的每一个配对。一次小的英文行文修改，动辄花掉数十倍于其应得份额的 token 用量与分钟数，被惩罚的恰恰是契约想要的行为：在同一个 PR（Pull Request）里把对侧文件一并带上。
+
+## 决策
+
+配对更新基于生成的简报（briefing）运行，而非基于指导语料；只有新建配对仍走整篇文档工作流，后者保持不变。
+
+- **`pnpm run gen-translation-brief [--apply] [pair...]`**（[scripts/gen-translation-brief.ts](../../../../scripts/gen-translation-brief.ts)，组装逻辑在 [scripts/translation-brief.ts](../../../../scripts/translation-brief.ts)）针对每个失去同步的配对，打印被改一侧从其记录在案的上次确认 blob 到当前工作区的 diff，并附上以能安全对齐的最窄粒度映射的这次改动，映射失败时粒度确定性地逐级放宽：仅落在配对中逐字节一致的围栏代码块内的改动会直接算出（`--apply` 会把它拼接进对侧文件，并在写入前用配对门禁的结构签名校验所得结果）；否则，每个有改动的 Markdown 单元（标题、段落、表格行、列表项、围栏代码块、块引用、HTML 块、分隔线、链接定义；匹配依据是以容器为作用域的种类序列）都带上各自的上次确认源文、当前源文与当前对侧文本及行号；无法对齐的单元回退到按深度匹配的标题章节；当章节也无法对齐或两侧同时漂移时，简报会明说这一点并省略映射，而不是靠猜。术语表行只与改动块匹配（英文术语按词边界匹配，含复数变形）；当目标侧是中文时，简报还会跟踪每个相关术语在整篇文档中的首次出现：一旦某次编辑使其移位，腾出的与接收的两处区间就会附一条解释性说明加入简报，因为「首次出现」括注必须随之移动。单元映射、代码拼接与首次出现机制采纳了[增量提示词流水线工作](https://github.com/deepseek-harness/deepseek-harness/pull/684)中的规划器设计；该项工作中接入提供方的对比评测，已为自动流水线独立验证了同一套范围阶梯。简报就是译者的全部工作集；简报回答不了的决策，仍以完整的真源文档作为升级求证路径。
+- **[dsh-translate-docs](../../../skills/dsh-translate-docs/SKILL.md) 中的更新路径**消费这份简报：机械类改动（只涉及围栏代码块）用 `--apply` 应用，不动用 subagent；行文类 diff 交给 subagent，其提示词就是简报本身，而非指导语料；核验只对改动块逐句进行，不覆盖整篇文档。
+- **配对门禁接受配对参数。**`verify-translation-pairing [pair...]` 只检查被点名的配对（配对三个文件中的任意一个，或其裸词干，都能指代该配对）；全语料扫描仍是 `doc-sync`（文档同步门禁）与 CI 运行的无参数形式。`--write` 现在要求点名已确认的配对：裸 `--write` 会拒绝执行，重新记录全部配对必须显式写 `--write --all`；原因是旧的裸形式会默默为树中每一个漂移的配对背书，包括调用者从未看过的那些，纯行文层面的漂移于是可以永远保持绿灯。每份记录的注释都写明针对该配对自身的按对命令。
+
+## 基准测试
+
+该决策来自对本仓库历史上十次真实配对更新的受控回放（2026 年 7 月；每例改动 1 到 64 行英文，涵盖 README、RFC、Agent Note（agent 决策记录）与用户文档）。每个样例都在临时仓库中重建到其真实的上次确认状态，英文改动保持未提交，再用全新的 subagent 分别跑过相互竞争的各条工作流：维持现状的语料加载路径、简报路径、无指导对照组、整篇重译、小模型上的简报路径，以及每个 agent（智能体）一次处理三对文档的批量方案。产出先经机械门禁把关，再由评委盲评打分；评委还同时收到真实的历史更新与原样未动的陈旧对侧文件作为对照。
+
+- 简报路径在盲评的忠实性、保留度与流畅度上与现状路径打平（两者都达到或超过真实历史更新的水平），而在未发生停滞的样例上只花费约三分之一的 token 用量与墙钟时间（全部十例的中位数：相对 token 成本单位 276k 对 595k，轮次数 14 对 32）。
+- 整篇重译被证实有害，而不只是浪费：它丢弃经评审的措辞，盲评保留度因此崩塌（4.4/10 对 9.8）；它还使各更新组保持住的既定术语发生漂移（既定译法本就写在对侧文件自身的正文里）；而且它是成本最高的一组。
+- 无指导对照组的质量同样立得住（对一次更新有约束力的上下文，是 diff 加上对侧文件自身经评审的正文，而非指导语料），但简报以几乎可忽略的额外成本，换来固定的工作集、内联的术语，以及两侧同时漂移的警告。
+- 以简报为输入，小模型的表现与大模型持平，因此更新路径不再假定翻译必须由前沿模型完成。
+- 把三对文档合并给同一个 subagent，相比三次各自带简报的运行没有可靠的节省，还把互不相关的失败耦合在一起；该方案被否决。
+

+## 曾考虑的替代方案
+
+- **保留原工作流，只让门禁支持按对检查**：门禁扫描本是较小的开销，大头在语料加载与翻查历史。只收窄检查范围，约 3 倍的开销仍会原地保留。
+- **把整篇重译作为更新路径**（朴素流水线的做法）：依据基准测试证据否决，理由是保留度崩塌、术语漂移、成本最高。契约的最小更新规则得以延续，且从此有数据支撑。
+- **每个 subagent 批量处理多对文档**：否决。没有实测出节省（简报本身已对固定内容做了去重），而且一对文档停滞或陷入混乱会把其余配对一并拖住。
+- **在伴随记录中保存逐段的翻译记忆条目**（用分段 hash 取代整文件 hash）：否决。配对两侧的段落边界可以合理地不同，任一侧都可能先撰写，这类条目还会不断膨胀并在合并时产生冲突。基于现有整文件 hash 按需计算的区间映射，在对齐可信时能恢复同样的对齐关系，不可信时会明确说明。
+- **给自动提示词流水线加一个更新模式（prompt-v5）**：推迟，本文不做设计。今天没有任何调用方在驱动 [scripts/translation-prompt.ts](../../../../scripts/translation-prompt.ts)，实际的成本中心是 agent 路径。流水线在拥有消费方之前，维持其整篇文档的 v4 契约。
+
+## 后果
+
+- 一次小的行文修改，其对侧更新如今只需生成一份简报，外加一个小而聚焦的任务（不读指导语料、不翻查历史、循环内不做全语料扫描），同一 PR 内完成更新的义务保持不变；低成本的路径与正确的路径指向同一个方向。
+- 简报生成器成为一致性记录的第二个消费方：记录的 blob hash 如今还驱动 diff 还原与章节映射，这进一步强化了如实维护记录的动机。
+- 不带参数的 `--write` 不再可用；靠肌肉记忆的调用者必须点名配对或传 `--all`。这正是目的所在：批量背书如今是一个可见的、有意为之的动作。
+- 按对检查意味着一个更新循环可以在别处某个无关配对处于红灯时自己保持绿灯；`doc-sync`/CI 中的全语料检查仍然承载树级不变式。
+- 区间映射只在上次确认源文、当前源文与当前对侧文本三方的种类序列一致时才信任一处对齐；映射失败时粒度确定性地逐级放宽（单元 → 章节 → 整篇文档）而不是靠猜，因此被重构过的文档拿到的是一份明确写着「请自行定位相关区域」的简报，绝不会是一张错误的地图。
+- 「首次出现」的一次移位可能让简报扩大到直接改动块之外；这一成本是「首次出现」契约的明确后果，而非对齐启发式。

+# Agent Note: CI failover runbook — hosted pools → in-house pool
+
+Status: implemented
+
+English | [中文](2026-07-26-ci-failover-runbook.zh.md)
+
+## Problem
+
+The three required Linux worker jobs in [CI](../../../../.github/workflows/ci.yml) (`node 24 / static`, `node 24 / coverage`, `node 24 / snapshots and artifacts`) run on the hosted enterprise 32-core pools; the required verdict job that aggregates them (`all checks passed`) runs on standard `ubuntu-latest`. When the enterprise pools degrade — jobs queue indefinitely or the enterprise labels vanish — every open pull request becomes unmergeable, and the ordinary recovery of merging a fix is itself deadlocked behind the very required checks that cannot run. **Scope: this switch recovers an enterprise Linux-pool outage.** The verdict's other required dependencies (`node-compat`, `python-sdk`, `windows`) stay on standard hosted runners by design (the portable boundary); in a broader GitHub-hosted capacity failure that also takes out the standard pools, those dependencies still block `all checks passed`, and only the Windows leg has no in-house substitute at all — during the 2026-07-27 outage the standard pools recovered first, which is the ordering this design bets on. An outage therefore needs a switch any responder with repository write access can throw without merging anything.
+
+## Decision
+
+Each of the three required Linux worker jobs — and the `all checks passed` verdict job, which would otherwise stay queued on the failed pool even after every worker passed — resolves its runner pool through the `DSH_CI_FAILOVER` repository variable. Unset (normal), they run on the hosted enterprise pools. Set to `selfhosted` by any repository writer, all four retarget onto the in-house self-hosted `vm-backup` pool, coverage and snapshot concurrency drop to shared-VM bounds, and the hosted-path pnpm cache restores are skipped. The switch is writer-manageable repository state, not a merge, so it works while every check is red. The in-house pool's readiness is continuously re-proven by the `serial / linux (self-hosted standby)` lane, which runs the complete unsharded aggregate on every master push.
+
+### What the in-house pool is
+
+`vm-backup`: one 64-core VM, six always-on systemd-managed runner instances. Check the latest `serial / linux (self-hosted standby)` run before switching: a green standby is verified-yesterday capacity.
+
+### Switch (any repository writer, ~1 minute, no merge)
+
+1. Repository **Settings → Secrets and variables → Actions → Variables → New repository variable**: name `DSH_CI_FAILOVER`, value `selfhosted`.
+2. Retrigger the required jobs so they re-resolve their pool. Jobs already **queued** for the hosted labels do not retarget and cannot be re-run in place, so for the documented indefinite-queue outage, cancel the stuck run and re-run all jobs, or push a new commit; "Re-run failed jobs" only helps once a job has actually failed rather than queued.
+3. That is the entire switch. Under failover the workflow also, automatically: drops `DSH_COVERAGE_MAX_WORKERS` to 8 and `DSH_SNAPSHOT_MAX_CONCURRENCY` to 12 (sized for six always-on instances: worst case 6 × 8 = 48 coverage workers on the 64-core VM) (shared-VM contention bounds), and skips the hosted-path pnpm cache restores (the VM's persistent store serves warm installs).
+
+#**Dependabot exception.** All four selectors deliberately exclude `dependabot[bot]`: under failover, Dependabot PRs stay queued for the hosted pool rather than executing dependency-supplied code on the persistent VM. A Dependabot PR that remains queued during an outage is expected behavior, not a failed switch; it completes when the hosted pool recovers.
+
+**Who can flip the variable.** GitHub's API lets any collaborator with write access manage repository variables, so the switch is writer-level, not strictly admin-only. In this repository's trust model that is not an escalation: the runner group admits all workflows of this private, fork-disabled repository (a deliberate trade to make PR-ref failover possible at all), so any writer could already reach the VM by pushing a branch workflow. The boundary against untrusted code is repository membership; the variable only routes work for members.
+
+## Capacity during failover
+
+Six always-on instances absorb normal PR traffic (the pool's steady-state load is one serial standby job per master push, so failover capacity is effectively the full pool). If queues still build, register additional instances with an org registration token (org Settings → Actions → Runners → New runner). Clone an existing runner directory **excluding its identity files** — `rsync -a --exclude '.runner*' --exclude '.credentials*' --exclude '_diag' --exclude '_work' <src>/ <dst>/` (the globs also catch `.runner_migrated`/`.credentials_migrated`, which GitHub writes on migrated runners and which equally trigger the already-configured refusal) — then run `config.sh` (copying `.runner`/`.credentials` verbatim makes it refuse with "already configured"), and **start the listener**: `sudo ./svc.sh install ubuntu && sudo ./svc.sh start`. Registration alone leaves the runner offline; only a started service adds capacity. About a minute per instance.
+
+
+### Switch back
+
+Delete the `DSH_CI_FAILOVER` variable (or set it to anything other than `selfhosted`). New runs resolve back to the hosted enterprise pools. Remove any extra instances that were registered during the incident.
+
+### Trust boundary
+
+The variable is writer-manageable repository state; a pull request event itself can neither set it nor read a different value into effect, and the selector expressions live in workflow definitions. Note that under failover, `pull_request` runs execute the PR merge ref's own workflow definition — the boundary against untrusted code is repository membership (private, forking disabled, Dependabot excluded by the selectors), not the variable. Note on runner-group policy: pinning the runner group to the master-ref workflow is **incompatible** with this failover — the four failover jobs are `pull_request` runs evaluated from PR merge refs, and a master-pinned group leaves them queued (observed live on 2026-07-27; the group was widened to all workflows of this repository to unblock the switch). A stricter runner-side policy therefore costs PR failover; the shipped posture accepts repository-scoped, all-workflow group access.
+
+## Alternatives considered
+
+**Merge a workflow change to switch pools.** Rejected because the outage that motivates the switch is exactly the state in which no PR can merge: the required checks are the ones failing. A repository variable is writer-manageable state that takes effect on re-run without a merge.
+
+**Keep the self-hosted pool always in the required path.** Rejected because it trades hosted-pool availability for the in-house VM's, moving a single point of failure rather than adding a fallback. The variable keeps the hosted pools primary and the self-hosted pool a proven, one-action standby.
+
+## Consequences
+
+Recovering from a hosted-pool outage is a single variable (any writer) plus a re-run, with no merge on the critical path. The cost is a second runner topology to keep working: the standby lane exercises it on every master push so the failover target never goes stale, and the concurrency and cache-restore branches in `ci.yml` carry a `selfhosted` leg that must stay in step with the hosted leg.

+# Agent Note: CI 故障切换手册 — 托管池 → 自有池
+
+Status: implemented
+
+[English](2026-07-26-ci-failover-runbook.md) | 中文
+
+## 问题
+
+[CI](../../../../.github/workflows/ci.yml) 中三个必需的 Linux 工作作业（`node 24 / static`、`node 24 / coverage`、`node 24 / snapshots and artifacts`）运行在托管的企业级 32 核池上；聚合它们的必需判定作业（`all checks passed`）运行在标准 `ubuntu-latest` 上。当企业池发生故障——作业无限排队或企业标签消失——所有开启的拉取请求都无法合并，而"合并一个修复"这一常规恢复手段本身正被那些无法运行的必需检查死锁。**适用范围：本切换恢复的是企业级 Linux 池故障。**判定作业的其余必需依赖（`node-compat`、`python-sdk`、`windows`）按设计留在标准托管运行器上（可移植边界）；若更大范围的 GitHub 托管容量故障连标准池一并击倒，这些依赖仍会阻塞 `all checks passed`，且只有 Windows 这条腿完全没有自有替代——2026-07-27 的故障中标准池率先恢复，本设计押注的正是这一顺序。因此故障需要一个任何具备仓库写权限的响应者都能在不合并任何代码的情况下触发的开关。
+
+## 决策
+
+三个必需的 Linux 工作作业——以及 `all checks passed` 判定作业（若不随切换，即使全部工作作业通过，它仍会滞留在故障池的队列中）——各自通过仓库变量 `DSH_CI_FAILOVER` 解析运行器池。变量不存在（正常）时它们运行在托管企业池上；由任何具备写权限的协作者设为 `selfhosted` 时，四者全部切换到公司自有的自托管 `vm-backup` 池，coverage 与 snapshot 的并发降到共享虚拟机上限，并跳过托管路径的 pnpm 缓存恢复。这个开关是写者可管理的仓库状态而非一次合并，因此在所有检查都是红色时仍然有效。自有池的就绪状态由 `serial / linux (self-hosted standby)` 通道持续验证——每次 master 推送都在其上运行完整的未分片聚合流程。
+
+### 自有池是什么
+
+`vm-backup`：一台 64 核虚拟机，6 个常驻 systemd 管理的运行器实例。切换前先看 `serial / linux (self-hosted standby)` 最近一次运行：绿色 = 这套环境昨天刚被全量验证过。
+
+### 切换步骤（任何具备写权限的协作者，约 1 分钟，无需合并）
+
+1. 仓库 **Settings → Secrets and variables → Actions → Variables → New repository variable**：名称 `DSH_CI_FAILOVER`，值 `selfhosted`。
+2. 重新触发必需作业，使其重新解析运行器池。已经为托管标签**排队**的作业不会重定向，也无法原地 re-run，因此对于本手册所述的无限排队故障，应取消卡住的运行并 re-run all jobs，或推送一个新提交；“Re-run failed jobs”只有在作业真正失败（而非仍在排队）时才有用。
+3. 切换到此完成。故障切换状态下工作流还会自动：把 `DSH_COVERAGE_MAX_WORKERS` 降为 8、`DSH_SNAPSHOT_MAX_CONCURRENCY` 降为 12（按 6 个常驻实例定容：最坏 6 × 8 = 48 个覆盖率工作进程对 64 核）（共享虚拟机的争抢上限），并跳过托管路径的 pnpm 缓存恢复（虚拟机的持久 store 直接提供热安装）。
+
+#**Dependabot 例外。**四个选择器都刻意排除了 `dependabot[bot]`：故障切换期间，Dependabot 拉取请求继续在托管池排队，而不是把依赖方提供的代码放到持久化虚拟机上执行。故障期间 Dependabot PR 持续排队是预期行为而非切换失败；托管池恢复后它会自行完成。
+
+**谁能扳动这个变量。**GitHub 的 API 允许任何具有写权限的协作者管理仓库变量，因此该开关实际是写者级而非严格的管理员级。在本仓库的信任模型下这并不构成越权：runner group 接纳本私有、禁 fork 仓库的全部工作流（这是让 PR 引用的故障切换得以成立的刻意取舍），因此任何写者本就可以通过推送分支工作流触达这台虚拟机。抵御不可信代码的边界是仓库成员资格；变量只是为成员路由工作。
+
+## 切换期间的容量
+
+6 个常驻实例可承接正常 PR 流量（该池平时唯一的稳态负载是每次 master 推送一个串行热备作业，故障切换时几乎全池可用）。若仍出现排队，用组织级注册 token（组织 Settings → Actions → Runners → New runner）追加注册实例。复制现有 runner 目录时**必须排除身份文件**——`rsync -a --exclude '.runner*' --exclude '.credentials*' --exclude '_diag' --exclude '_work' <src>/ <dst>/`（通配同时排除 `.runner_migrated`/`.credentials_migrated`——GitHub 会在迁移过的运行器上写入这些文件，它们同样会触发 already-configured 拒绝）——再跑 `config.sh`（原样拷贝 `.runner`/`.credentials` 会使其以 "already configured" 拒绝），然后**启动监听器**：`sudo ./svc.sh install ubuntu && sudo ./svc.sh start`。仅注册不会上线；只有启动了服务的 runner 才会增加容量。每个约一分钟。
+
+
+### 切回
+
+删除 `DSH_CI_FAILOVER` 变量（或改为 `selfhosted` 以外的任何值），新的运行即解析回托管企业池。若故障期间追加注册过实例，将其移除。
+
+### 信任边界
+
+该变量是写者可管理的仓库状态；`pull_request` 事件本身既不能设置它，也不能让不同的值生效，选择器表达式存在于工作流定义中。需要注意：故障切换期间，`pull_request` 运行执行的是 PR merge 引用自带的工作流定义——抵御不可信代码的边界是仓库成员资格（私有、禁 fork、选择器排除 Dependabot），而非该变量。关于 runner group 策略的说明：把 runner group 绑定到 master 引用的工作流与本故障切换机制**不兼容**——四个故障切换作业是从 PR merge 引用求值的 `pull_request` 运行，master 绑定的组会让它们持续排队（2026-07-27 实际故障中亲历；当时将组放宽为本仓库全部工作流才疏通了切换）。更严格的运行器侧策略以牺牲 PR 故障切换为代价；当前采用的形态是仓库范围、全工作流的组访问。
+
+## 曾考虑的替代方案
+
+**通过合并一次工作流改动来切换池。** 否决，因为触发切换的故障状态恰恰是任何 PR 都无法合并的状态：必需检查正是失败的那些。仓库变量是写者可管理的状态，重跑即生效，无需合并。
+
+**让自托管池长期处于必需路径中。** 否决，因为这是拿托管池的可用性去换自有虚拟机的可用性，只是搬移了单点故障而非增加回退。该变量让托管池保持主路径，自托管池作为一个经过验证、一步即可启用的热备。
+
+## 后果
+
+从托管池故障中恢复只需一个变量（任何写者可设）加一次重跑，关键路径上没有合并。代价是要维护第二套运行器拓扑：热备通道在每次 master 推送时都运行它，使故障切换目标永不失效；而 `ci.yml` 中的并发与缓存恢复分支带有一条 `selfhosted` 支路，必须与托管支路保持同步。

+# Agent Note: Wine-run Windows blocking gates on Linux runners
+
+Status: implemented
+
+English | [中文](2026-07-27-wine-windows-gates-experiment.zh.md)
+
+## Problem
+
+The pull-request Windows lane exists to prove the two blocking win32 surfaces — the workspace build and the production site — and it ran on hosted `windows-2025`, the slowest job in the required matrix: 7–9 minutes against 1.5–2.5 for the Linux jobs, so the Windows VM's boot, setup, and filesystem costs dominated every pull request's critical path.
+
+The question the experiment answered: can a plain Linux runner produce an equivalent win32 signal for the blocking surfaces at Linux wall clock, so no Windows VM sits on the pull-request path at all?
+
+## Decision
+
+The required pull-request `windows` job in [ci.yml](../../../../.github/workflows/ci.yml) (`windows node 24 / wine blocking`) runs the blocking gate commands on `ubuntu-latest` under Wine with real Windows binaries: a checksum-verified win-x64 Node.js executes `tsc -b`, `tsdown`, and the VitePress production build, so the win32 branches of the toolchain — backslash path handling, `CreateProcess` spawn semantics, PE loading of `@esbuild/win32-x64`, and the rolldown/rollup MSVC `.node` addons — actually execute. The master `serial-windows` job is untouched: the complete native-kernel inventory, including the observational portability gates this lane does not run, still executes on real `windows-2025` on every master push.
+
+Dependencies install natively on Linux with `supportedArchitectures` extended to win32-x64, which materializes the Windows platform packages in the same store; the cmd-shim layer is bypassed by invoking each tool's JavaScript entrypoint directly, the same processes `run-gates` ultimately spawns. `nodeLinker: hoisted` is load-bearing, not stylistic: the independent prototype in [PR #689](https://github.com/deepseek-harness/deepseek-harness/pull/689) kept pnpm's default isolated layout — including a faithful offline Windows-pnpm re-install over a Linux-prefetched store — and Windows Node under Wine still could not resolve `@esbuild/win32-x64` or load the koffi prebuild through the isolated symlink chain, failing before any repository gate ran. A flat layout with real files is what makes the gates reachable at all; #689's checksum pinning is adopted, while its Windows-pnpm-installs-the-tree goal is explicitly given up (the install contract stays Linux-tested here).
+
+The lane holds the wall clock of the Linux CI jobs through four levers: the master-refreshed pnpm store cache (restore-only, same key as the Linux jobs), Wine provisioning (apt install, Windows Node download, `wineboot`) running concurrently with `pnpm install`, the two blocking surfaces running concurrently — the same shape `run-gates` gives them on native Windows — and an apt-archive cache keyed on the runner image, seeded from master by the `wine apt cache` job so every pull request restores from the default-branch scope.
+
+Four environment constraints shape the job, each found as a red run: Ubuntu's `wine64` package alone puts nothing on PATH (install `wine`, the dispatcher); Node under Wine cannot attach stdio to the Actions runner's pipes (`Socket open EBADF` at bootstrap — every invocation routes stdio through a file); Wine does not realpath pnpm's isolated-layout Unix symlinks (the hoisted layout above); and Wine cannot create Windows symlinks (`ENOTSUP` from VitePress's `linkVue` — the `vue` link is laid down host-side before the gate).
+
+## Measured results
+
+Measured on 2026-07-27, warm caches, pull-request trigger, standard 2-core `ubuntu-latest`: 2m46s end-to-end — setup and cache restores ~17s, concurrent install+provision 33s, concurrent gates 110s — against 1.5–2.5 minutes for the Linux CI jobs and 7–9 minutes for the replaced `windows-2025` job. A cold-cache run pays roughly one extra minute. An 8-core benchmark leg was defined during the experiment but never left the restricted `dsh-ubuntu-*` pool's queue; the standard-runner number met the target, so no larger box is used.
+
+## Alternatives considered
+
+**Keep the hosted `windows-2025` pull-request job (status quo).** Nothing wrong with its signal, only its latency: 7–9 minutes for two build commands, the slowest required job in the matrix. It survives as the master serial reference, where completeness matters more than latency.
+
+**A full Windows guest under QEMU/KVM inside the Linux runner.** Real NT kernel, so full fidelity including case-insensitive NTFS and ConPTY — but tens of minutes of image download and unattended install before the first gate runs (40m19s measured end-to-end on the sibling experiment branch `exp/kvm-windows-ci`). Promotable only with disk-image caching that pressures the Actions cache budget.
+
+**Windows pnpm performing the install under Wine ([PR #689](https://github.com/deepseek-harness/deepseek-harness/pull/689)).** The higher-fidelity variant of this same idea: MinGit and pnpm staged into the prefix, a Linux prefetch filling the store, then `pnpm install --offline` run by Windows Node so the install contract itself executes as win32. It reached the install but not the gates — Wine's networking could not reach the registry directly, and the isolated `node_modules` layout defeated resolution of the Windows platform packages even after a clean offline install. This lane trades that fidelity away (hoisted layout, Linux-side install) to reach the gates; the two records are complementary halves of the same verdict.
+
+**Filesystem-semantics lanes on Linux (casefolded ext4, filename lint).** Catches the highest-frequency Windows breakage class for near-zero cost but proves nothing about win32 binaries. Explored as the sibling experiment branch `exp/casefold-windows-ci`; complementary to, not competitive with, this lane.
+
+**Windows containers.** Not possible: Windows containers require a Windows host kernel; a hosted Linux runner cannot run them.
+
+**Dropping the Windows lane.** Rejected — win32 is a first-class product target: the koffi-backed DACL and durable-namespace modules, ConPTY-based PTY sessions, and Windows path policy all ship in `packages/`.
+
+## Consequences
+
+Every pull request's Windows verdict now arrives in Linux-job time on free standard capacity, and no Windows VM allocation sits on the pull-request critical path; `all checks passed` consumes the same `windows` job id it always did.
+
+What the trade costs: Wine reimplements Win32 over a case-sensitive ext4 — NTFS case-insensitivity, real DACLs, ConPTY, and crash-durability semantics are not proved here, and the observational portability inventory (duplication, publint, node-next types, built-package invariants on win32) no longer runs on pull requests at all. The master `serial-windows` reference owns all of that: a Wine-green pull request can still fail the native-kernel master run, and that failure mode is accepted as post-merge. The lane also inherits Wine-specific divergences as permanent job structure — file-routed stdio, the host-side `vue` link, the hoisted layout — so a future toolchain change that depends on isolated-layout semantics or in-process symlink creation will surface here first as a Wine failure rather than a product failure, and triage must classify it as such. If Wine reds ever recur without product cause, the recorded fallback is reverting the `windows` job to the pre-Wine `windows-2025` definition preserved in git history.

+# Agent Note: 在 Linux runner 上用 Wine 运行 Windows 阻断门禁
+
+Status: implemented
+

+
+## 问题
+
+Pull request 的 Windows 通道存在的意义是证明两个阻断性 win32 表面——workspace 构建与生产站点——它此前运行在托管 `windows-2025` 上，是必需矩阵中最慢的作业：7–9 分钟，对照 Linux 作业的 1.5–2.5 分钟，因此 Windows VM 的启动、准备与文件系统开销主导了每个 pull request 的关键路径。
+
+实验回答的问题是：一台普通 Linux runner 能否以 Linux 墙钟为阻断表面产出等效的 win32 信号，让 pull request 路径上完全没有 Windows VM？
+
+## 决策
+
+[ci.yml](../../../../.github/workflows/ci.yml) 中必需的 pull request `windows` 作业（`windows node 24 / wine blocking`）在 `ubuntu-latest` 上通过 Wine 用真实 Windows 二进制运行阻断门禁命令：校验和验证过的 win-x64 Node.js 执行 `tsc -b`、`tsdown` 与 VitePress 生产构建，因此工具链的 win32 分支——反斜杠路径处理、`CreateProcess` 派生语义、`@esbuild/win32-x64` 的 PE 加载、以及 rolldown/rollup 的 MSVC `.node` 插件——都真正执行。master 的 `serial-windows` 作业原封不动：完整的原生内核清单，包括本通道不运行的观察性可移植性门禁，仍在每次 master push 时于真实 `windows-2025` 上执行。
+
+依赖在 Linux 上原生安装，`supportedArchitectures` 扩展到 win32-x64，使 Windows 平台包物化进同一个 store；通过直接调用各工具的 JavaScript 入口绕开 cmd-shim 层，这正是 `run-gates` 最终派生的那些进程。`nodeLinker: hoisted` 是承重的，不是风格问题：[PR #689](https://github.com/deepseek-harness/deepseek-harness/pull/689) 的独立原型保留了 pnpm 默认的 isolated 布局——包括在 Linux 预取的 store 上忠实地用 Windows pnpm 离线重装——而 Wine 下的 Windows Node 依然无法穿过 isolated 符号链接链解析 `@esbuild/win32-x64` 或加载 koffi 预编译产物，在任何仓库门禁运行前就失败了。扁平的真实文件布局才让门禁变得可达；本通道采纳了 #689 的校验和固定，同时明确放弃其"Windows pnpm 安装依赖树"的目标（安装契约在此仍由 Linux 侧验证）。
+
+该通道靠四个杠杆保持 Linux CI 作业的墙钟：master 刷新的 pnpm store 缓存（只恢复，与 Linux 作业同键）、Wine 供给（apt 安装、Windows Node 下载、`wineboot`）与 `pnpm install` 并发运行、两个阻断表面并发运行——与 `run-gates` 在原生 Windows 上给它们的形状相同——以及按 runner 镜像为键的 apt 归档缓存，由 master 的 `wine apt cache` 作业播种，使每个 pull request 都能从默认分支作用域恢复。
+
+四条环境约束塑造了该作业，每条都以一次红色运行被发现：Ubuntu 的 `wine64` 包本身不往 PATH 放任何东西（要装 `wine` 调度器）；Wine 下的 Node 无法把 stdio 接到 Actions runner 的管道上（引导期 `Socket open EBADF`——所有调用都经文件中转 stdio）；Wine 不对 pnpm isolated 布局的 Unix 符号链接做 realpath（即上文的 hoisted 布局）；Wine 无法创建 Windows 符号链接（VitePress 的 `linkVue` 报 `ENOTSUP`——`vue` 链接在门禁前由宿主侧铺好）。
+
+## 实测结果
+
+2026-07-27 实测，热缓存，pull request 触发，标准 2 核 `ubuntu-latest`：端到端 2 分 46 秒——准备与缓存恢复约 17 秒，并发安装+供给 33 秒，并发门禁 110 秒——对照 Linux CI 作业的 1.5–2.5 分钟与被替换的 `windows-2025` 作业的 7–9 分钟。冷缓存约多付一分钟。实验期间定义过 8 核基准腿，但它从未离开受限 `dsh-ubuntu-*` 池的队列；标准 runner 的数字已达标，故不使用更大的机器。
+
+## 考虑过的替代方案
+
+**保留托管 `windows-2025` 的 pull request 作业（现状）。** 其信号没有问题，问题只在延迟：为两条构建命令花 7–9 分钟，是必需矩阵中最慢的作业。它作为 master 串行参照存续——在那里完整性比延迟更重要。
+
+**在 Linux runner 内用 QEMU/KVM 跑完整 Windows 客户机。** 真实 NT 内核，保真度完整，包括大小写不敏感的 NTFS 与 ConPTY——但首个门禁运行前要花数十分钟下载镜像并做无人值守安装（兄弟实验分支 `exp/kvm-windows-ci` 实测端到端 40 分 19 秒）。只有配上会挤压 Actions 缓存预算的磁盘镜像缓存才可晋升。
+
+**在 Wine 下由 Windows pnpm 执行安装（[PR #689](https://github.com/deepseek-harness/deepseek-harness/pull/689)）。** 同一想法的更高保真度变体：把 MinGit 与 pnpm 放进 prefix，用 Linux 预取填充 store，再由 Windows Node 运行 `pnpm install --offline`，让安装契约本身以 win32 身份执行。它到达了安装但没到达门禁——Wine 的网络无法直接访问 registry，且 isolated 的 `node_modules` 布局即便在干净的离线安装后也挫败了 Windows 平台包的解析。本通道用掉这份保真度（hoisted 布局、Linux 侧安装）来换取门禁可达；两份记录是同一裁决互补的两半。
+
+**Linux 上的文件系统语义通道（casefold ext4、文件名 lint）。** 以近零成本捕获最高频的 Windows 破坏类别，但对 win32 二进制什么也证明不了。作为兄弟实验分支 `exp/casefold-windows-ci` 探索；与本通道互补而非竞争。
+
+**Windows 容器。** 不可行：Windows 容器要求 Windows 宿主内核；托管 Linux runner 无法运行。
+
+**砍掉 Windows 通道。** 已否决——win32 是一等产品目标：基于 koffi 的 DACL 与持久命名空间模块、基于 ConPTY 的 PTY 会话、以及 Windows 路径策略都随 `packages/` 交付。
+
+## 结果
+
+每个 pull request 的 Windows 裁决现在以 Linux 作业的时间在免费标准容量上到达，pull request 关键路径上不再有任何 Windows VM 分配；`all checks passed` 消费的仍是原来的 `windows` 作业 id。
+
+这笔交易的代价：Wine 在大小写敏感的 ext4 之上重实现 Win32——NTFS 大小写不敏感、真实 DACL、ConPTY 与崩溃持久性语义在此都未被证明，且观察性可移植性清单（duplication、publint、node-next 类型、win32 上的构建包不变量）完全不再于 pull request 上运行。master 的 `serial-windows` 参照拥有这一切：Wine 绿灯的 pull request 仍可能在原生内核的 master 运行上失败，该失败模式被接受为合并后处理。该通道还把 Wine 特有的分歧继承为永久的作业结构——文件中转的 stdio、宿主侧的 `vue` 链接、hoisted 布局——因此未来依赖 isolated 布局语义或进程内符号链接创建的工具链变更会先在这里以 Wine 失败而非产品失败的形式浮现，分诊必须如此归类。若 Wine 红灯在无产品原因的情况下反复出现，记录在案的退路是把 `windows` 作业还原为 git 历史中保存的 Wine 之前的 `windows-2025` 定义。

+# Agent Note: Consolidate gate scripts on already-present deps and builtins
+
+Status: implemented
+
+English | [中文](2026-07-26-consolidate-gate-scripts-on-existing-deps.zh.md)
+
+## Problem
+
+The `scripts/` gates mostly used the right tools (`node:fs` `globSync` in 15+ gates, mdast/micromark in the markdown gates), but a handful of stragglers hand-rolled what a sibling gate already did with an existing dependency or builtin:
+
+- **Duplicated fence scanners.** `scripts/md-fences.ts` (~55 lines, consumed by `doc-typecheck.ts`) and `extractEquivBlocks` in `scripts/verify-type-equiv.ts` (~39 lines) were two copies of the same regex line-scanner for fenced code blocks, while `scripts/verify-mermaid.ts` already extracted fences by visiting mdast `code` nodes — and `markdownProseLines` in `scripts/markdown.ts` itself parsed to mdast but then hand-tracked fence state with a second regex. The regex scanners only recognized backtick fences at column 0, so they silently disagreed with the mdast-based gates on tilde and indented fences.
+- **Hand-rolled argv parsing.** `parseOptions` in `scripts/publint-all.ts` and its near-identical copy in `scripts/verify-built-package-invariants.mjs` (~26 lines) stepped argv indexes manually, while sibling scripts (`verify-runtime-closure.ts`, `build-exe-for-python-sdk.ts`, `packages/sdk/scripts/src/args.ts`) already used the `node:util` `parseArgs` builtin.
+- **Hand-rolled directory walks.** Five sites re-derived nested `readdirSync` walks that `globSync` covers: `verify-runtime-closure.ts` (packages + vendor manifests), `dev-web.ts` `discoverPluginDirs`, `verify-package-paths.ts` `realPackageNames`, `verify-client-domain-graph.ts` `listSources`, and `publint-all.ts` `addPath` (~55–65 lines total). `scripts/package-invariants.ts` shows the one-line `globSync` template.
+
+No new dependency was needed anywhere; every replacement is an existing devDep or a Node builtin.
+
+## Decision
+
+- A shared mdast fence helper, `markdownFences` in `scripts/markdown.ts`, visits `code` nodes for the language, full info string, body, and 1-based opening-fence line; `doc-typecheck.ts` and `verify-type-equiv.ts` extract fences through it. `md-fences.ts` and the duplicated `extractEquivBlocks` scanner are deleted, and `markdownProseLines` derives fenced lines from the parsed `code` nodes' positions instead of a second regex.
+- Both CLIs parse argv via `parseArgs`; unknown options and missing values still fail loud, with `parseArgs`'s own error text instead of the bespoke usage strings.
+- The five straggler walks use `globSync`. The walks in `check-workspace-constraints.ts` and `clean.ts` stay: they need dirent-level detail to diagnose malformed trees, which glob-by-pattern cannot report.
+
+## Alternatives considered
+
+- **A new glob/walking dependency (`tinyglobby`, `fdir`).** Rejected: the builtin already won repo-wide; these were stragglers, not a gap.
+- **`p-map` for `publint-all.ts`'s ~19-line ordered worker pool.** Deliberately left out: one new devDep for one small deletion is at the edge of the [dependency policy](../process/2026-07-26-dependencies-over-hand-rolling.md) bar, and the pool's requirements (bounded workers, deterministic order, env override) are documented in the [parallel-gates note](../process/2026-07-06-parallel-pre-push-gates.md). Fold it in only if `p-map` earns a second consumer.
+- **Leaving the fence scanners.** Rejected: two drifting copies of a parser beside a third correct implementation is exactly the duplication the shared `markdown.ts` helper exists to prevent, and the column-0-backtick-only limitation was a latent inconsistency between sibling gates.
+
+## Consequences
+
+- One fence parser: every markdown gate now classifies fences through mdast, so tilde, indented, and 4-backtick container fences behave identically everywhere. The docs tree contained no fence shape the regex scanners mishandled, so gate results are unchanged on the tree that landed the swap: `pnpm run doc-sync` and each rewritten gate ran before and after with byte-identical output (`doc-typecheck` block/opt-out counts, `verify-type-equiv` match counts, `publint`, `verify-built-package-invariants`, `verify-runtime-closure`, `verify-package-paths`, `verify-client-domain-graph`, and both package-README prose gates).
+- `verify-type-equiv` still rejects an unterminated type-equivalence fence: mdast silently closes an unterminated block at end-of-file (its comparisons could then pass), so the shared helper reports whether a closing delimiter exists and the gate errors on an unclosed block, preserving the removed scanner's rejection. The `doc-typecheck` scanner never had that error path.
+- `parseArgs` keeps the last value of a duplicated option instead of erroring — a dev-tool edge case the tests don't pin, accepted in exchange for deleting the two bespoke parsers. (Strict mode still rejects a `--`-prefixed token where a value is expected, matching the replaced parsers.)

+# Agent Note: 把门禁脚本统一到已有依赖与内置模块上
+
+Status: implemented
+
+[English](2026-07-26-consolidate-gate-scripts-on-existing-deps.md) | 中文
+
+## 问题
+
+`scripts/` 下的门禁大多本已在用正确的工具（15 个以上的门禁使用 `node:fs` 的 `globSync`，markdown 门禁使用 mdast/micromark），但少数几个掉队的脚本曾手写同类门禁早已用既有依赖或内置模块完成的事情：
+
+- **重复的围栏扫描器。**`scripts/md-fences.ts`（约 55 行，由 `doc-typecheck.ts` 消费）和 `scripts/verify-type-equiv.ts` 中的 `extractEquivBlocks`（约 39 行）曾是同一个围栏代码块正则行扫描器的两份拷贝，而 `scripts/verify-mermaid.ts` 早已通过访问 mdast `code` 节点来提取代码围栏；`scripts/markdown.ts` 自己的 `markdownProseLines` 也曾先解析成 mdast，再用第二个正则手工跟踪围栏状态。这两个正则扫描器只识别第 0 列的反引号围栏，因此在波浪线围栏和缩进围栏上与基于 mdast 的门禁悄悄不一致。
+- **手写的 argv 解析。**`scripts/publint-all.ts` 中的 `parseOptions` 和 `scripts/verify-built-package-invariants.mjs` 中与之几乎相同的拷贝（约 26 行）曾手工推进 argv 下标，而同类脚本（`verify-runtime-closure.ts`、`build-exe-for-python-sdk.ts`、`packages/sdk/scripts/src/args.ts`）早已在使用 `node:util` 的内置 `parseArgs`。
+- **手写的目录遍历。**五处代码曾各自重写 `globSync` 已覆盖的嵌套 `readdirSync` 遍历：`verify-runtime-closure.ts` 对 packages 与 vendor manifest（元数据清单）的扫描、`dev-web.ts` 的 `discoverPluginDirs`、`verify-package-paths.ts` 的 `realPackageNames`、`verify-client-domain-graph.ts` 的 `listSources`，以及 `publint-all.ts` 的 `addPath`（合计约 55–65 行）。`scripts/package-invariants.ts` 展示了一行式的 `globSync` 模板。
+
+所有替换都不需要引入新依赖；每一处替换用的都是既有的 devDependency 或 Node 内置模块。
+
+## 决策
+
+- `scripts/markdown.ts` 中的共享 mdast 围栏辅助函数 `markdownFences` 访问 `code` 节点，读取语言、完整 info string、块体以及以 1 起始的开围栏行号；`doc-typecheck.ts` 和 `verify-type-equiv.ts` 通过它提取代码围栏。`md-fences.ts` 和重复的 `extractEquivBlocks` 扫描器已删除，`markdownProseLines` 也改为从解析出的 `code` 节点位置推导围栏内的行，而不再用第二个正则。
+- 两个 CLI 都改用 `parseArgs` 解析 argv；未知选项和缺失取值仍然大声失败，只是错误文案换成了 `parseArgs` 自带的文本，而非原先手写的用法字符串。
+- 那五处掉队的目录遍历改用 `globSync`。`check-workspace-constraints.ts` 和 `clean.ts` 中的遍历保留：它们需要 dirent 级别的细节来诊断结构异常的目录树，按模式匹配的 glob 报告不了这些信息。
+
+## 曾考虑的替代方案
+
+- **新的 glob/目录遍历依赖（`tinyglobby`、`fdir`）。**不予采纳：内置模块已在全仓库范围内胜出；这几处只是掉队者，不是能力缺口。
+- **用 `p-map` 替换 `publint-all.ts` 中约 19 行的有序 worker 池。**刻意未纳入：为一次小删除引入一个新 devDependency，正处在[依赖策略](../process/2026-07-26-dependencies-over-hand-rolling.md)门槛的边缘，而且该池的需求（worker 数量有界、确定性顺序、环境变量覆盖）已记录在[并行 pre-push 门禁决策记录](../process/2026-07-06-parallel-pre-push-gates.md)中。仅当 `p-map` 赢得第二个消费方时再顺带纳入。
+- **保留这两个围栏扫描器。**不予采纳：在第三个正确实现旁边放着两份逐渐漂移的解析器拷贝，正是共享的 `markdown.ts` 辅助函数要防止的那种重复；「只认第 0 列反引号」的限制也是同类门禁之间的潜在不一致。
+
+## 后果
+
+- 只剩一个围栏解析器：所有 markdown 门禁现在都经由 mdast 归类代码围栏，因此波浪线围栏、缩进围栏和四反引号容器围栏在各处的行为完全一致。文档树中不存在正则扫描器处理有误的围栏形态，所以在落地这次替换的代码树上门禁结果不变：`pnpm run doc-sync` 及每个被改写的门禁在改动前后各跑一遍，输出逐字节相同（`doc-typecheck` 的块数/opt-out 计数、`verify-type-equiv` 的匹配计数、`publint`、`verify-built-package-invariants`、`verify-runtime-closure`、`verify-package-paths`、`verify-client-domain-graph`，以及两个包 README 散文门禁）。
+- `verify-type-equiv` 仍然拒绝未闭合的类型等价围栏：mdast 会在文件末尾静默闭合未闭合的代码块（其比较随后可能通过），因此共享辅助函数会报告闭合定界符是否存在，门禁在块未闭合时报错，保留了被删扫描器的这条拒绝路径。`doc-typecheck` 的扫描器本来就没有这条错误路径。
+- `parseArgs` 对重复出现的选项保留最后一个值而不报错——一个测试未固定的开发工具边缘用例，作为删除两份手写解析器的交换被接受。（严格模式下，需要取值处遇到以 `--` 开头的 token 仍会拒绝，与被替换的解析器行为一致。）

+# Agent Note: Replace the hand-rolled SSE parser in llm-deepseek with eventsource-parser
+
+Status: implemented
+
+English | [中文](2026-07-26-eventsource-parser-for-deepseek-sse.zh.md)
+
+## Problem
+
+`packages/llm/llm-deepseek/src/sse.ts` hand-implemented Server-Sent Events parsing: a streaming `TextDecoder`, event-block splitting on `\r?\n\r?\n`, `data:` payload extraction and joining, comment/field skipping, the `[DONE]` sentinel, a `STREAM_CLOSED` error on EOF without it, and a flush of a final unterminated event block. The file was ~67 lines with ~108 lines of dedicated tests (`tests/sse.spec.ts`) re-proving SSE spec behavior — UTF-8 split across chunks, CRLF handling, multi-`data:` joining, no-space-after-colon — that a maintained parser already guarantees. Its only consumer is `adapter.ts` (`yield* translate(parseSse(response.body))`).
+
+This is exactly the surface `eventsource-parser` owns: the de-facto standard SSE parser (it underlies the Vercel AI SDK and the MCP SDK), zero-dependency, actively maintained, and already present in this repo's lockfile transitively via `@modelcontextprotocol/sdk` — so adopting it directly adds no new supply-chain surface in practice.
+
+## Decision
+
+`sse.ts` delegates SSE framing to `EventSourceParserStream` from `eventsource-parser/stream`: `parseSse` pipes the response body through `new TextDecoderStream()` then `new EventSourceParserStream()` and keeps only the DeepSeek protocol shim — yield each event's `data`, terminate on `[DONE]`, and throw `LlmError('STREAM_CLOSED')` when the stream ends without the sentinel. All required builtins (`TextDecoderStream`, `pipeThrough`, async-iterable `ReadableStream`) exist at the Node ^22.19 engine floor. The spec-conformance tests are gone; `tests/sse.spec.ts` pins only the `[DONE]`/`STREAM_CLOSED`/EOF contract. `eventsource-parser` is `llm-deepseek`'s second runtime dependency after schemastery. The [twin-adapters note](../architecture/2026-06-13-twin-llm-adapters.md) and the `dsh-llm` JSDoc that branded this adapter "hand-rolled fetch + SSE parsing" now describe it as direct fetch with library-framed SSE.
+
+The library also strips a leading BOM (the hand-rolled parser would fail to match `data:` after one) and offers `maxBufferSize` hardening the hand-rolled parser lacked.
+
+## Alternatives considered
+
+- **Keep the hand-rolled parser.** Defensible under the [twin-adapters decision](../architecture/2026-06-13-twin-llm-adapters.md): the adapter is deliberately the hand-rolled design-verification twin of the pi-ai adapter. But that note's load-bearing distinction is owning the fetch/translate internals versus delegating to a full provider SDK; a ~700-byte SSE micro-parser is transport plumbing, not the design under verification. The twin-adapters note now states that reading explicitly.
+- **`createParser({onEvent})` callback API instead of the stream.** Works fed by a manual `TextDecoder` loop, but the `pipeThrough` composition deletes more of the hand-rolled code.
+
+## Consequences
+
+- The remaining shim only encodes the DeepSeek `[DONE]`/`STREAM_CLOSED` protocol; SSE framing edge cases are eventsource-parser's contract and are no longer re-proven here.
+- One deliberate robustness deviation is dropped: the hand-rolled parser flushed a final event block that lacked its terminating blank line, so a trailing `data: [DONE]` without `\n\n` still yielded DONE. eventsource-parser is spec-strict and only dispatches on the blank line, so that shape is now `STREAM_CLOSED`. Real providers and `dsh-llm-mock-server` always terminate events properly — the flush was a robustness nicety, not an observed provider shape — and `tests/sse.spec.ts` pins the new truncation verdict for that tail.
+- The documented "hand-rolled" identity of the twin adapter narrows to the fetch/translate internals; the twin-adapters note was updated in the same change rather than leaving the claim stale.

+# Agent Note: 用 eventsource-parser 替换 llm-deepseek 中手写的 SSE 解析器
+
+Status: implemented
+
+[English](2026-07-26-eventsource-parser-for-deepseek-sse.md) | 中文
+
+## 问题
+
+`packages/llm/llm-deepseek/src/sse.ts` 曾手写实现 SSE（Server-Sent Events）解析：一个流式 `TextDecoder`、按 `\r?\n\r?\n` 切分事件块、提取并拼接 `data:` 载荷、跳过注释与其他字段、`[DONE]` 哨兵、在未见哨兵即 EOF 时抛出 `STREAM_CLOSED` 错误，以及对最后一个未终结事件块的 flush。该文件约 67 行，另有约 108 行专属测试（`tests/sse.spec.ts`）重复验证 SSE 规范行为——UTF-8 字符被切分到多个分片、CRLF 处理、多条 `data:` 拼接、冒号后无空格——而这些行为，持续维护的解析器早已有保证。它唯一的消费方是 `adapter.ts`（`yield* translate(parseSse(response.body))`）。
+
+这恰好是 `eventsource-parser` 负责的接口面：事实标准的 SSE 解析器（Vercel AI SDK 和 MCP SDK 都构建在它之上），零依赖，持续维护，并且已通过 `@modelcontextprotocol/sdk` 作为传递依赖出现在本仓库的 lockfile 中——因此直接采用它实际上不增加新的供应链接触面。
+
+## 决策
+
+`sse.ts` 将 SSE 分帧委托给 `eventsource-parser/stream` 的 `EventSourceParserStream`：`parseSse` 把响应 body 依次管道接入 `new TextDecoderStream()` 和 `new EventSourceParserStream()`，只保留 DeepSeek 协议垫层——逐个产出事件的 `data`，遇到 `[DONE]` 终止，流在未见哨兵时结束则抛出 `LlmError('STREAM_CLOSED')`。所需的全部内置能力（`TextDecoderStream`、`pipeThrough`、可异步迭代的 `ReadableStream`）在 Node ^22.19 引擎下限即已存在。规范符合性测试已删除；`tests/sse.spec.ts` 只固定 `[DONE]`/`STREAM_CLOSED`/EOF 契约。`eventsource-parser` 是 `llm-deepseek` 继 schemastery 之后的第二个运行时依赖。曾把该适配器标为「手写 fetch + SSE 解析」的[孪生适配器 Agent Note（agent 决策记录）](../architecture/2026-06-13-twin-llm-adapters.md)与 `dsh-llm` JSDoc，现在将其描述为直接 fetch 加库分帧的 SSE。
+
+该库还会剥离开头的 BOM（手写解析器在 BOM 之后会无法匹配 `data:`），并提供手写解析器缺少的 `maxBufferSize` 加固能力。
+
+## 曾考虑的替代方案
+
+- **保留手写解析器。** 依据[孪生适配器决策](../architecture/2026-06-13-twin-llm-adapters.md)，这一选择有辩护余地：该适配器有意作为 pi-ai 适配器的手写设计验证孪生体。但那份 Agent Note 起支撑作用的区分在于「自行持有 fetch/translate 内部实现」与「委托给完整的提供方 SDK」；一个约 700 字节的 SSE 微型解析器属于传输层管道，不是被验证的设计本身。孪生适配器 Agent Note 现已明确写出这一解读。
+- **改用 `createParser({onEvent})` 回调 API 而非流。** 配合手动的 `TextDecoder` 循环可以工作，但 `pipeThrough` 组合方式能删除更多手写代码。
+
+## 后果
+
+- 剩下的垫层只编码 DeepSeek 的 `[DONE]`/`STREAM_CLOSED` 协议；SSE 分帧边界情形属于 eventsource-parser 的契约，不再在这里重复验证。
+- 放弃了一处有意为之的健壮性偏离：手写解析器会 flush 缺少终结空行的最后一个事件块，因此末尾的 `data: [DONE]` 即使没有 `\n\n` 也仍产出 DONE。eventsource-parser 严格遵循规范，只在空行处分发事件，所以这种形态现在是 `STREAM_CLOSED`。真实提供方和 `dsh-llm-mock-server` 总是正确终结事件——该 flush 只是健壮性上的锦上添花，并非实际观测到的提供方形态——`tests/sse.spec.ts` 固定了对该尾部的新截断判定。
+- 孪生适配器有文档记录的「手写」身份收窄到 fetch/translate 内部实现；孪生适配器 Agent Note 在同一次变更中更新，而不是让声明陈旧下去。

+# Agent Note: Replace tool-web's regex HTML-to-markdown converter with turndown
+
+Status: implemented
+
+English | [中文](2026-07-26-turndown-for-tool-web-html-markdown.zh.md)
+
+## Problem
+
+`dsh-tool-web`'s `src/html.ts` (~86 lines, ~40 lines of dedicated tests; deleted by this change) converted fetched HTML to markdown with regexes: strip script/style/noscript/comments, convert `<a>`/`<h1-6>`/`<li>`, decode numeric entities plus a 12-entry named-entity table, collapse whitespace. The module's own JSDoc said "A richer converter can replace it without changing the seam or tool schema", and the README's Known Limitations documented it as "a minimal regex converter, not an HTML parser — tables, images, and nested formatting are lost." The [web capability seam note](../architecture/2026-06-24-web-capability-seam.md) assigns HTML→markdown to this package as presentation, so the swap point was exactly here. The converter's output is model-visible on every fetched HTML page; no keyless snapshot exercised `web_fetch`, so no expected outputs pinned it.
+
+## Decision
+
+`packages/web/tool-web/src/fetch.ts` owns a module-level [`turndown`](https://github.com/mixmark-io/turndown) instance (`headingStyle: 'atx'`, `codeBlockStyle: 'fenced'`, `bulletListMarker: '-'` — fixed model-facing presentation, not deployment tunables) with `@joplin/turndown-plugin-gfm`'s composite `gfm` plugin for tables/strikethrough and `remove(['script', 'style', 'noscript'])` replacing the old wholesale drops. `formatFetchOutput` limits both the source prefix converted synchronously and the complete rendered output with `fetchMaxOutputChars` (default 200,000), so a custom provider cannot make conversion work unbounded before the output cap applies. The HTML arm then guards conversion twice: a conservative linear lexical pass treats comment contents conservatively, skips raw-text bodies, honors quoted tag text, and passes a body through raw when its stack crosses 512 levels; a try/catch also falls back to raw HTML when turndown rejects markup the guard cannot model. The GFM cell rule is overridden to ignore `colspan`, which Markdown cannot represent, rather than letting an untrusted numeric attribute synthesize arbitrary empty cells. `html.ts` and its conversion tests are deleted; the source/output bounds, fallback, and status-header/truncation-footer formatting are tested in `tests/tool-web.spec.ts`, and the README's Known Limitations trades the regex-converter caveat for the bounded degradation cases. The gfm plugin ships no types; `src/turndown-plugin-gfm.d.ts` declares the one imported export over `@types/turndown` (a devDependency).
+
+The dependency-weight question the proposal flagged resolves in favor of the swap: `@deepseek-ai/dsh-tool-web` is in the single-file-executable closure ([single-exe note](../architecture/2026-07-10-single-file-executable-sdk-runtime-distribution.md)), and the exe's asset globs would pack ~7.9 MB of the three packages as published — but ~6 MB of that is `@mixmark-io/domino`'s test corpus (`test/**`), with runtime `lib/` at ~550 KB against a ~174 MB artifact, under 0.5% either way.
+
+## Snapshot coverage
+
+The previously-missing keyless `web_fetch` snapshot ships with the change as the acp-agent scenario `web-fetch`: `examples/acp-agent/web.cordis.yml` composes the web seam, the real `dsh-web-fetch-local` provider, `tool-web` with `search: false`, and `web-fetch-fixture-server.mjs` — a loopback HTTP fixture on a fixed port (the fetched URL is part of the recorded transcript) serving deterministic HTML with named entities, a GFM table, and nested formatting. Recording and keyless replay both drive the real HTTP fetch and conversion; the pinned tool result is the turndown output, and the scenario pins the `web` header class (the `web_fetch` schema and guidance).
+
+## Alternatives considered
+
+- **`@mozilla/readability` + a DOM.** Solves a different problem (content extraction, not conversion) and drags a heavier DOM dependency; the seam only asks for markdown rendering of whatever the fetch returned.
+- **Keep the regex converter.** It was an explicit v1 placeholder per its own JSDoc; keeping it meant model-visible quality (tables, images, nested formatting) stayed lost for the cost of maintaining bespoke entity tables.
+- **The minimal `entities`-only variant.** The proposal's fallback position: replace only the entity-decoding third of `html.ts` with the zero-dependency `entities` package, deleting less but avoiding the dependency-weight question. Not taken because the closure math above made the weight immaterial while the full swap deletes the whole hand-rolled converter and its documented quality gaps.
+- **`turndown-plugin-gfm` (the original) instead of `@joplin/turndown-plugin-gfm`.** The original is unmaintained (last publish 2018); the Joplin fork is current against turndown 7 and actively released.
+
+## Consequences
+
+- **Bought**: standards-based model-visible markdown — ordinary tables, images, strikethrough, nested emphasis, fenced code blocks, and the complete named-entity set — plus the deletion of the bespoke converter and its entity tables.
+- **Paid**: two runtime dependencies (`turndown` → `@mixmark-io/domino`) enter tool-web and therefore the exe closure (~550 KB of runtime code as measured above); overlong input is converted only through a bounded prefix, pathological nesting falls back to raw HTML, and spanning table cells are flattened because GFM has no corresponding syntax.
+- Model-visible output changed on every fetched HTML page; nothing pinned the old output, and the new snapshot pins the new one.
+
+## Testing
+
+- `packages/web/tool-web/tests/tool-web.spec.ts` covers the turndown conversion surface (entities, links, tables, nesting, script/style/noscript removal), ignored table spans, source-prefix and complete-output bounds, fast raw-HTML passthrough for deep or deceptively closed nesting, linear handling of malformed tags, the residual converter-throw fallback, and exact and tiny output budgets; per-file coverage on the package src is 100%.
+- The `web-fetch` acp-agent snapshot pins the assembled behavior keylessly end to end (real Loader composition, real HTTP fetch, real conversion).

+# Agent Note: 用 turndown 替换 tool-web 的正则 HTML 转 markdown 转换器
+
+Status: implemented
+
+[English](2026-07-26-turndown-for-tool-web-html-markdown.md) | 中文
+
+## 问题
+
+`dsh-tool-web` 的 `src/html.ts`（约 86 行，另有约 40 行专属测试；已由本变更删除）曾用正则表达式把抓取到的 HTML 转成 markdown：剥离 script、style、noscript 标签与注释，转换 `<a>`/`<h1-6>`/`<li>`，解码数字实体外加一张 12 项的命名实体表，并折叠空白。该模块自身的 JSDoc 写明「A richer converter can replace it without changing the seam or tool schema」，README 的 Known Limitations 章节也把它记载为「a minimal regex converter, not an HTML parser — tables, images, and nested formatting are lost」。[web 能力 seam 决策记录](../architecture/2026-06-24-web-capability-seam.md)把 HTML 转 markdown 作为呈现职责划归本包（package），因此替换点恰好就在这里。每个抓取到的 HTML 页面上，该转换器的输出都对模型可见；此前没有任何无密钥快照执行到 `web_fetch`，因此没有预期输出固定它的行为。
+
+## 决策
+
+`packages/web/tool-web/src/fetch.ts` 持有一个模块级 [`turndown`](https://github.com/mixmark-io/turndown) 实例（`headingStyle: 'atx'`、`codeBlockStyle: 'fenced'`、`bulletListMarker: '-'`——固定的面向模型呈现方式，不是部署可调项），配合 `@joplin/turndown-plugin-gfm` 的组合 `gfm` 插件提供表格／删除线支持，并用 `remove(['script', 'style', 'noscript'])` 替代旧实现的整体剥离。`formatFetchOutput` 通过 `fetchMaxOutputChars`（默认 200,000）同时限制同步转换的源前缀和完整渲染输出，因此自定义提供方无法在输出上限生效前造成无界的转换工作。随后，HTML 分支对转换做双重防护：保守的线性词法扫描会保守处理注释内容，跳过原始文本元素的内容，正确处理标签内的引号文本，并在栈深超过 512 层时将主体作为原始 HTML 直接透传；当 turndown 拒绝守卫无法建模的标记时，try/catch 同样回退为原始 HTML。GFM 单元格规则被覆写为忽略 `colspan`；Markdown 无法表示它，这也避免了不受信任的数值属性凭空合成任意数量的空单元格。`html.ts` 及其转换测试已删除；源／输出上限、回退以及状态头／截断页脚格式化均在 `tests/tool-web.spec.ts` 中有测试覆盖，README 的 Known Limitations 用有界降级情形替换了正则转换器警示。gfm 插件不带类型声明；`src/turndown-plugin-gfm.d.ts` 基于 `@types/turndown`（devDependency）声明了唯一被导入的导出。
+
+提案标记的依赖体积问题的裁决结果支持替换：`@deepseek-ai/dsh-tool-web` 在单文件可执行文件闭包内（[single-exe 决策记录](../architecture/2026-07-10-single-file-executable-sdk-runtime-distribution.md)），可执行文件的资产 glob 会把这三个包按发布原样打入约 7.9 MB——但其中约 6 MB 是 `@mixmark-io/domino` 的测试语料（`test/**`），运行时 `lib/` 仅约 550 KB，相对约 174 MB 的产物，两种口径都不到 0.5%。
+
+## 快照覆盖
+
+此前缺失的无密钥 `web_fetch` 快照随本变更以 acp-agent 场景 `web-fetch` 落地：`examples/acp-agent/web.cordis.yml` 组合了 web seam、真实的 `dsh-web-fetch-local` 提供方、`search: false` 的 `tool-web`，以及 `web-fetch-fixture-server.mjs`——一个固定端口（抓取的 URL 是录制 transcript（文本记录）的一部分）上的回环 HTTP fixture，提供包含命名实体、GFM 表格与嵌套格式的确定性 HTML。录制与无密钥回放都驱动真实的 HTTP 抓取与转换；固定住的工具结果就是 turndown 的输出，该场景同时固定 `web` header 类（`web_fetch` 的 schema 与指引）。
+
+## 曾考虑的替代方案
+
+- **`@mozilla/readability` 加一个 DOM。** 它解决的是另一个问题（内容提取，而非格式转换），还会拖入更重的 DOM 依赖；这个 seam 只要求把抓取返回的内容渲染成 markdown。
+- **保留正则转换器。** 按其自身 JSDoc 的说法，它本来就是明确的 v1 占位实现；保留它意味着模型可见的质量（表格、图片、嵌套格式）继续缺失，代价还是维护一套自制实体表。
+- **仅引入 `entities` 的最小变体。** 提案中的退守方案：只用零依赖的 `entities` 包替换 `html.ts` 中的实体解码部分，删得更少但完全避开依赖体积问题。未采纳：上述闭包测算表明体积无关紧要，而完整替换能删掉整个手写转换器及其记录在案的质量缺口。
+- **用原版 `turndown-plugin-gfm` 而非 `@joplin/turndown-plugin-gfm`。** 原版已无人维护（最后发布于 2018 年）；Joplin 分叉与 turndown 7 保持同步并持续发布。
+
+## 后果
+
+- **收益**：基于标准的模型可见 markdown——普通表格、图片、删除线、嵌套强调、围栏代码块以及完整的命名实体集——并删除了自制转换器及其实体表。
+- **代价**：两个运行时依赖（`turndown` → `@mixmark-io/domino`）进入 tool-web 进而进入可执行文件闭包（如上实测约 550 KB 运行时代码）；超长输入只转换有界前缀，病态嵌套回退为原始 HTML，跨列表格单元格会被展平，因为 GFM 没有对应语法。
+- 每个抓取到的 HTML 页面上模型可见的输出都已变化；旧输出本无任何固定，新快照固定了新输出。
+
+## 测试
+
+- `packages/web/tool-web/tests/tool-web.spec.ts` 覆盖 turndown 转换面（实体、链接、表格、嵌套、script/style/noscript 移除）、被忽略的表格跨列、源前缀与完整输出上限、深层或带欺骗性闭合嵌套的快速原始 HTML 透传、畸形标签的线性处理、残余的转换器抛错回退，以及恰好达到上限和极小的输出预算；该包 src 的逐文件覆盖率为 100%。

 `launchWebScaffold()` boots the real web composition from the shipped `apps/cli/cordis.yml` through the vendored Loader's include mechanism — the same tree and mechanism `AppCLIEntry` drives for `dsh web`. Divergences ride include patches over that tree, the ACP `cordis.snapshot.yml` pattern expressed in-process: temp `persistenceRoot`, `workspace-context` disabled (recorded fixtures must not embed this repo's AGENTS.md), `session-title-llm` disabled (its fire-and-forget title call would race the loop for the session's replay cursor), the webserver row pinned to port 0 with the built dist, and in keyless modes `llm-deepseek` disabled. A patch id that stops matching a row fails the boot sweep loudly instead of drifting. The boot runs `chdir`'d to the temp workspace so the api-gateway's `process.cwd()` session default, tool cwds, and fixtures agree; the `dsh web` bin's own glue (argv, profile json, AppCLIEntry) stays held by the keyless CLI smokes in `smoke-real.e2e.ts`. Setup rollback and ordinary close both dispose the Cordis tree before removing the two owned temp roots, attempt every cleanup independently, and report cleanup failures without masking the setup failure.

The direct install rather than an inserted replay plugin row is deliberate: it returns the `ReplayHandle` the teardown consumption check needs.

 - **Path canon**: the stored value = `fs.realpath(input)` (trailing slashes, `..`, and symlinks all resolved); uniqueness = string equality after normalization (a symlink resolving to the same directory counts as a collision). A missing directory makes create reject outright (realpath fails — a workspace must point at an existing directory; "Create new = make the directory" is upper-layer interaction: mkdir first, then create). The session cwd in attach checks follows the same canon. Single-valued cwd + unique path ⇒ one session structurally belongs to at most one workspace; double bookkeeping is impossible on the write side.
 - **Title**: a display name, defaults to `basename(path)`, mutable, duplicates allowed. Ownership is never derived from cwd as a fallback — cwd cannot express ordering, and ownership is a workspace-side fact; sessions started headless belong to no workspace.
 - Consumers see only the `Workspace` interface; `WorkspaceEntity` stays inside the package (a single implementation does not pre-split a seam). Entities are unique per id (registry cache); the record snapshot is swapped in place after each write, and the outside sees getters only. Every write funnels through the entity's internal `mutate(fn)` → `table.update`, with `updatedAt` refreshed inside mutate. Domain objects never cross RPC; next phase the wire layer projects records into zod wire schemas.
- **Workspace deletion is future work as a whole** (settled 2026-07-24): the registry ships no delete method this phase — the half-measure "delete the record, keep the sessions" is not exposed; deletion and the session cascade (`recursive` parameter, running checks, bottom-up order, crash-rerun convergence) land as one complete semantic together with the session delete primitive; the order then is delete sessions one by one → prune the ledger → delete the workspace record.

-# Agent Note: Consolidate gate scripts on already-present deps and builtins
-
-Status: proposed
-
-English | [中文](2026-07-26-consolidate-gate-scripts-on-existing-deps.zh.md)
-
-## Problem
-
-The `scripts/` gates mostly use the right tools (`node:fs` `globSync` in 15+ gates, mdast/micromark in the markdown gates), but a handful of stragglers hand-roll what a sibling gate already does with an existing dependency or builtin:
-
- **Duplicated fence scanners.** `scripts/md-fences.ts` (~55 lines, consumed by `doc-typecheck.ts`) and `extractEquivBlocks` in `scripts/verify-type-equiv.ts` (~39 lines) are two copies of the same regex line-scanner for fenced code blocks, while `scripts/verify-mermaid.ts` already extracts fences by visiting mdast `code` nodes via the shared `scripts/markdown.ts` helpers — and `markdownProseLines` in `markdown.ts` itself parses to mdast but then hand-tracks fence state with a second regex. The regex scanners only recognize backtick fences at column 0, so they silently disagree with the mdast-based gates on tilde and indented fences.
- **Hand-rolled argv parsing.** `parseOptions` in `scripts/publint-all.ts` and its near-identical copy in `scripts/verify-built-package-invariants.mjs` (~26 lines) step argv indexes manually, while sibling scripts (`verify-runtime-closure.ts`, `build-exe-for-python-sdk.ts`, `packages/sdk/scripts/src/args.ts`) already use the `node:util` `parseArgs` builtin.
- **Hand-rolled directory walks.** Five sites re-derive nested `readdirSync` walks that `globSync` covers: `verify-runtime-closure.ts` (packages + vendor manifests), `dev-web.ts` `discoverPluginDirs`, `verify-package-paths.ts` `realPackageNames`, `verify-client-domain-graph.ts` `listSources`, and `publint-all.ts` `addPath` (~55–65 lines total). `scripts/package-invariants.ts` shows the one-line `globSync` template.
-
-No new dependency is needed anywhere; every replacement is an existing devDep or a Node builtin.
-
-## Proposal
-
- Extract a shared ~10–15-line mdast fence helper (visiting `code` nodes for `lang`, `meta`, `value`, `position.start.line`) into `scripts/markdown.ts`; rewrite `doc-typecheck.ts` and `verify-type-equiv.ts` onto it; delete `md-fences.ts` and the duplicated scanner; drop the redundant fence regex in `markdownProseLines`.
- Replace both `parseOptions` copies with `parseArgs`.
- Replace the five straggler walks with `globSync`. Keep the walks in `check-workspace-constraints.ts` and `clean.ts`: they need dirent-level detail to diagnose malformed trees, which glob-by-pattern cannot report.
-
-## Alternatives considered
-
- **A new glob/walking dependency (`tinyglobby`, `fdir`).** Rejected: the builtin already won repo-wide; these are stragglers, not a gap.
- **`p-map` for `publint-all.ts`'s ~19-line ordered worker pool.** Deliberately left out: one new devDep for one small deletion is at the edge of the [dependency policy](../../implemented/process/2026-07-26-dependencies-over-hand-rolling.md) bar, and the pool's requirements (bounded workers, deterministic order, env override) are documented in the [parallel-gates note](../../implemented/process/2026-07-06-parallel-pre-push-gates.md). Fold it in only if `p-map` earns a second consumer.
- **Leaving the fence scanners.** Rejected: two drifting copies of a parser beside a third correct implementation is exactly the duplication the shared `markdown.ts` helper exists to prevent, and the column-0-backtick-only limitation is a latent inconsistency between sibling gates.
-
-## Acceptance criteria
-
- `md-fences.ts` is gone; `doc-typecheck` and `verify-type-equiv` extract fences through `scripts/markdown.ts`; `pnpm run doc-sync` passes with unchanged results on the current tree (any delta traces to a fence shape the regex scanners mishandled).
- Both CLIs parse via `parseArgs`; unknown options still fail loud.
- The five walk sites use `globSync`; the gates they feed pass unchanged.
-
-## Risks
-
- Behavioral deltas on pathological markdown: mdast honors tilde/indented fences the regex scanners ignored, so `doc-typecheck`'s opt-out ratio could shift if any stray fence shape exists in the docs tree; verify by running `doc-sync` before/after.
- `parseArgs` keeps the last value of a duplicated option instead of erroring — a dev-tool edge case the tests don't pin. (Strict mode still rejects a `--`-prefixed token where a value is expected, matching the current parsers.)

-
-Status: proposed
-
-[English](2026-07-26-consolidate-gate-scripts-on-existing-deps.md) | 中文
-
-## 问题
-
-`scripts/` 下的门禁大多已经在用正确的工具（15 个以上的门禁使用 `node:fs` 的 `globSync`，markdown 门禁使用 mdast/micromark），但少数几个掉队的脚本仍在手写同类门禁早已用既有依赖或内置模块完成的事情：
-
- **重复的围栏扫描器。**`scripts/md-fences.ts`（约 55 行，由 `doc-typecheck.ts` 消费）和 `scripts/verify-type-equiv.ts` 中的 `extractEquivBlocks`（约 39 行）是同一个围栏代码块正则行扫描器的两份拷贝，而 `scripts/verify-mermaid.ts` 已经通过共享的 `scripts/markdown.ts` 辅助函数访问 mdast `code` 节点来提取代码围栏；`markdown.ts` 自己的 `markdownProseLines` 也是先解析成 mdast，再用第二个正则手工跟踪围栏状态。这两个正则扫描器只识别第 0 列的反引号围栏，因此在波浪线围栏和缩进围栏上与基于 mdast 的门禁悄悄不一致。
- **手写的 argv 解析。**`scripts/publint-all.ts` 中的 `parseOptions` 和 `scripts/verify-built-package-invariants.mjs` 中与之几乎相同的拷贝（约 26 行）手工推进 argv 下标，而同类脚本（`verify-runtime-closure.ts`、`build-exe-for-python-sdk.ts`、`packages/sdk/scripts/src/args.ts`）已经在使用 `node:util` 的内置 `parseArgs`。
- **手写的目录遍历。**五处代码各自重写了 `globSync` 已覆盖的嵌套 `readdirSync` 遍历：`verify-runtime-closure.ts` 对 packages 与 vendor manifest（元数据清单）的扫描、`dev-web.ts` 的 `discoverPluginDirs`、`verify-package-paths.ts` 的 `realPackageNames`、`verify-client-domain-graph.ts` 的 `listSources`，以及 `publint-all.ts` 的 `addPath`（合计约 55–65 行）。`scripts/package-invariants.ts` 展示了一行式的 `globSync` 模板。
-
-所有替换都不需要引入新依赖；每一处替换用的都是既有的 devDependency 或 Node 内置模块。
-
-## 提案
-
- 在 `scripts/markdown.ts` 中提取一个约 10–15 行的共享 mdast 围栏辅助函数（访问 `code` 节点，读取 `lang`、`meta`、`value`、`position.start.line`）；把 `doc-typecheck.ts` 和 `verify-type-equiv.ts` 改写到它上面；删除 `md-fences.ts` 和重复的扫描器；去掉 `markdownProseLines` 中冗余的围栏正则。
- 用 `parseArgs` 替换两份 `parseOptions` 拷贝。
- 用 `globSync` 替换那五处掉队的目录遍历。保留 `check-workspace-constraints.ts` 和 `clean.ts` 中的遍历：它们需要 dirent 级别的细节来诊断结构异常的目录树，按模式匹配的 glob 报告不了这些信息。
-
-## 曾考虑的替代方案
-
- **新的 glob/目录遍历依赖（`tinyglobby`、`fdir`）。**不予采纳：内置模块已在全仓库范围内胜出；这几处只是掉队者，不是能力缺口。
- **用 `p-map` 替换 `publint-all.ts` 中约 19 行的有序 worker 池。**刻意未纳入：为一次小删除引入一个新 devDependency，正处在[依赖策略](../../implemented/process/2026-07-26-dependencies-over-hand-rolling.md)门槛的边缘，而且该池的需求（worker 数量有界、确定性顺序、环境变量覆盖）已记录在[并行 pre-push 门禁决策记录](../../implemented/process/2026-07-06-parallel-pre-push-gates.md)中。仅当 `p-map` 赢得第二个消费方时再顺带纳入。
- **保留这两个围栏扫描器。**不予采纳：在第三个正确实现旁边放着两份逐渐漂移的解析器拷贝，正是共享的 `markdown.ts` 辅助函数要防止的那种重复；「只认第 0 列反引号」的限制也是同类门禁之间的潜在不一致。
-
-## 验收标准
-
- `md-fences.ts` 已删除；`doc-typecheck` 与 `verify-type-equiv` 通过 `scripts/markdown.ts` 提取代码围栏；`pnpm run doc-sync` 在当前代码树上通过且结果不变（如有差异，必须能追溯到正则扫描器处理有误的某种围栏形态）。
- 两个 CLI 都改用 `parseArgs` 解析；未知选项仍然大声失败。
- 五处遍历代码改用 `globSync`；它们供给的门禁保持原样通过。
-
-## 风险
-
- 病态 markdown 上的行为差异：mdast 会承认正则扫描器忽略的波浪线围栏和缩进围栏，因此如果文档树中存在任何零散的此类围栏形态，`doc-typecheck` 的 opt-out 比例可能变化；应在改动前后分别运行 `doc-sync` 加以验证。
- `parseArgs` 对重复出现的选项保留最后一个值而不报错——一个测试未固定的开发工具边缘用例。（严格模式下，需要取值处遇到以 `--` 开头的 token 仍会拒绝，与现有解析器行为一致。）

-# Agent Note: Replace the hand-rolled SSE parser in llm-deepseek with eventsource-parser
-
-Status: proposed

-English | [中文](2026-07-26-eventsource-parser-for-deepseek-sse.zh.md)
-
-## Problem
-
-`packages/llm/llm-deepseek/src/sse.ts` hand-implements Server-Sent Events parsing: a streaming `TextDecoder`, event-block splitting on `\r?\n\r?\n`, `data:` payload extraction and joining, comment/field skipping, the `[DONE]` sentinel, a `STREAM_CLOSED` error on EOF without it, and a flush of a final unterminated event block. The file is ~67 lines with ~108 lines of dedicated tests (`tests/sse.spec.ts`) re-proving SSE spec behavior — UTF-8 split across chunks, CRLF handling, multi-`data:` joining, no-space-after-colon — that a maintained parser already guarantees. Its only consumer is `adapter.ts` (`yield* translate(parseSse(response.body))`).
-
-This is exactly the surface `eventsource-parser` owns: the de-facto standard SSE parser (it underlies the Vercel AI SDK and the MCP SDK), zero-dependency, actively maintained, and already present in this repo's lockfile transitively via `@modelcontextprotocol/sdk` — so adopting it directly adds no new supply-chain surface in practice.
-
-## Proposal
-
-Replace `sse.ts` with `EventSourceParserStream` from `eventsource-parser/stream`: `response.body.pipeThrough(new TextDecoderStream()).pipeThrough(new EventSourceParserStream())`, keeping only the DeepSeek protocol shim (~10–25 lines): yield each event's `data`, terminate on `[DONE]`, and throw `LlmError('STREAM_CLOSED')` when the stream ends without the sentinel. All required builtins (`TextDecoderStream`, `pipeThrough`, async-iterable `ReadableStream`) exist at the Node ^22.19 engine floor. Delete the spec-conformance tests; keep the `[DONE]`/`STREAM_CLOSED`/EOF contract tests. Add `eventsource-parser` to `llm-deepseek`'s dependencies (its second runtime dep after schemastery). Update the [twin-adapters note](../../implemented/architecture/2026-06-13-twin-llm-adapters.md) and the `dsh-llm` JSDoc that brand this adapter "hand-rolled fetch + SSE parsing" in the same PR.
-
-The library also strips a leading BOM (the hand-rolled parser would fail to match `data:` after one) and offers `maxBufferSize` hardening the current parser lacks.
-
-## Alternatives considered
-
- **Keep the hand-rolled parser.** Defensible under the [twin-adapters decision](../../implemented/architecture/2026-06-13-twin-llm-adapters.md): the adapter is deliberately the hand-rolled design-verification twin of the pi-ai adapter. But the note's load-bearing distinction is owning the fetch/translate internals versus delegating to a full provider SDK; a ~700-byte SSE micro-parser is transport plumbing, not the design under verification. Whether that reading stands is the twin-note owner's call — this proposal explicitly needs their sign-off.
- **`createParser({onEvent})` callback API instead of the stream.** Works fed by a manual `TextDecoder` loop, but the `pipeThrough` composition deletes more of the hand-rolled code.
-
-## Acceptance criteria
-
- `sse.ts`'s parsing internals are gone; the remaining shim only encodes the DeepSeek `[DONE]`/`STREAM_CLOSED` protocol.
- `llm-deepseek` unit tests and the real-API e2e suite pass; keyless snapshots are unchanged (parsing is transport-internal and payload extraction is equivalent).
- The twin-adapters note and `dsh-llm` JSDoc no longer claim hand-rolled SSE parsing.
-
-## Risks
-
- One deliberate robustness deviation is lost: the hand-rolled parser flushes a final event block that lacks its terminating blank line, and `tests/sse.spec.ts` pins that a trailing `data: [DONE]` without `\n\n` still yields DONE. eventsource-parser is spec-strict and only dispatches on the blank line, so that shape becomes `STREAM_CLOSED`. Real providers and `dsh-llm-mock-server` always terminate events properly, so the pinned behavior is a robustness nicety, not an observed provider shape — drop the test, or keep a tiny buffer-tail check if the deviation is judged load-bearing.
- Dilutes the documented "hand-rolled" identity of the twin adapter; mitigated by updating the note in the same change rather than leaving the claim stale.

-## 问题
-
-`packages/llm/llm-deepseek/src/sse.ts` 手写实现了 SSE（Server-Sent Events）解析：一个流式 `TextDecoder`、按 `\r?\n\r?\n` 切分事件块、提取并拼接 `data:` 载荷、跳过注释与其他字段、`[DONE]` 哨兵、在未见哨兵即 EOF 时抛出 `STREAM_CLOSED` 错误，以及对最后一个未终结事件块的 flush。该文件约 67 行，另有约 108 行专属测试（`tests/sse.spec.ts`）重复验证 SSE 规范行为——UTF-8 字符被切分到多个分片、CRLF 处理、多条 `data:` 拼接、冒号后无空格——而这些行为，持续维护的解析器早已有保证。它唯一的消费方是 `adapter.ts`（`yield* translate(parseSse(response.body))`）。
-
-这恰好是 `eventsource-parser` 负责的接口面：事实标准的 SSE 解析器（Vercel AI SDK 和 MCP SDK 都构建在它之上），零依赖，持续维护，并且已通过 `@modelcontextprotocol/sdk` 作为传递依赖出现在本仓库的 lockfile 中——因此直接采用它实际上不增加新的供应链接触面。
-
-## 提案
-
-用 `eventsource-parser/stream` 的 `EventSourceParserStream` 替换 `sse.ts`：`response.body.pipeThrough(new TextDecoderStream()).pipeThrough(new EventSourceParserStream())`，只保留 DeepSeek 协议垫层（约 10–25 行）：逐个产出事件的 `data`，遇到 `[DONE]` 终止，流在未见哨兵时结束则抛出 `LlmError('STREAM_CLOSED')`。所需的全部内置能力（`TextDecoderStream`、`pipeThrough`、可异步迭代的 `ReadableStream`）在 Node ^22.19 引擎下限即已存在。删除规范符合性测试；保留 `[DONE]`/`STREAM_CLOSED`/EOF 契约测试。将 `eventsource-parser` 加入 `llm-deepseek` 的依赖（这是它继 schemastery 之后的第二个运行时依赖）。在同一个 PR（Pull Request）中更新[孪生适配器 Agent Note（agent 决策记录）](../../implemented/architecture/2026-06-13-twin-llm-adapters.md)以及 `dsh-llm` 中把该适配器标为「手写 fetch + SSE 解析」的 JSDoc。

-
-## 曾考虑的替代方案
-
- **保留手写解析器。** 依据[孪生适配器决策](../../implemented/architecture/2026-06-13-twin-llm-adapters.md)，这一选择有辩护余地：该适配器有意作为 pi-ai 适配器的手写设计验证孪生体。但那份 Agent Note 起支撑作用的区分在于「自行持有 fetch/translate 内部实现」与「委托给完整的提供方 SDK」；一个约 700 字节的 SSE 微型解析器属于传输层管道，不是被验证的设计本身。这一解读是否成立由孪生 Agent Note 的所有者裁定——本提案明确需要其签署确认。
- **改用 `createParser({onEvent})` 回调 API 而非流。** 配合手动的 `TextDecoder` 循环可以工作，但 `pipeThrough` 组合方式能删除更多手写代码。
-
-## 验收标准

- `sse.ts` 的解析内部实现消失；剩下的垫层只编码 DeepSeek 的 `[DONE]`/`STREAM_CLOSED` 协议。
- `llm-deepseek` 单元测试与真实 API 的 e2e 套件通过；无密钥快照不变（解析属于传输层内部，载荷提取等价）。
- 孪生适配器 Agent Note 与 `dsh-llm` 的 JSDoc 不再声称手写 SSE 解析。
-
-## 风险
-
- 会失去一处有意为之的健壮性偏离：手写解析器会 flush 缺少终结空行的最后一个事件块，`tests/sse.spec.ts` 固定了「末尾的 `data: [DONE]` 即使没有 `\n\n` 也仍产出 DONE」这一行为。eventsource-parser 严格遵循规范，只在空行处分发事件，因此这种形态会变成 `STREAM_CLOSED`。真实提供方和 `dsh-llm-mock-server` 总是正确终结事件，所以被固定的行为只是健壮性上的锦上添花，并非实际观测到的提供方形态：可以删除该测试；若判定该偏离确有支撑作用，也可以保留一个小型的缓冲区尾部检查。

-# Agent Note: Replace tool-web's regex HTML-to-markdown converter with turndown
-
-Status: proposed
-
-English | [中文](2026-07-26-turndown-for-tool-web-html-markdown.zh.md)
-
-## Problem
-
-`packages/web/tool-web/src/html.ts` (~86 lines, ~40 lines of dedicated tests) converts fetched HTML to markdown with regexes: strip script/style/noscript/comments, convert `<a>`/`<h1-6>`/`<li>`, decode numeric entities plus a 12-entry named-entity table, collapse whitespace. The module's own JSDoc says "A richer converter can replace it without changing the seam or tool schema", and the README's Known Limitations documents it as "a minimal regex converter, not an HTML parser — tables, images, and nested formatting are lost." The [web capability seam note](../../implemented/architecture/2026-06-24-web-capability-seam.md) assigns HTML→markdown to this package as presentation, so the swap point is exactly here. The converter's output is model-visible on every fetched HTML page; no keyless snapshot currently exercises `web_fetch`, so no expected outputs pin it.
-
-## Proposal
-
-Replace `htmlToMarkdown` with `turndown` (`new TurndownService().turndown(html)`), optionally with `turndown-plugin-gfm` for tables. The consumer switch in `fetch.ts` and the status-header/truncation-footer formatting stay. Wrap the call in try/catch falling back to the raw text path: the regex version could never throw; turndown on pathological HTML could. Delete `html.ts` and its conversion tests; keep tests for the fallback and the surrounding formatting. Update the README's Known Limitations to drop the regex-converter caveat.
-
-If the "deliberately minimal fallback" stance is preferred instead, a minimal variant still deletes the worst part: replace the entity-decoding third of the file (~30 lines: `decodeEntities`, `NAMED_ENTITIES`, `safeFromCodePoint`) with the zero-dependency `entities` package (already in the lockfile transitively), erasing the documented "about a dozen entities" limitation at near-zero risk.
-
-## Alternatives considered
-
- **`@mozilla/readability` + a DOM.** Solves a different problem (content extraction, not conversion) and drags a heavier DOM dependency; the seam only asks for markdown rendering of whatever the fetch returned.
- **Keep the regex converter.** It was an explicit v1 placeholder per its own JSDoc; keeping it means model-visible quality (tables, images, nested formatting) stays lost for the cost of maintaining bespoke entity tables.
- **The minimal `entities`-only variant.** Kept in the proposal as the fallback position; it deletes less but avoids the dependency-weight question entirely.
-
-## Acceptance criteria
-
- `web_fetch` renders tables/nested formatting via turndown (or, minimal variant: decodes all named entities), with the README limitation updated.
- Unit tests cover the fallback path; `pnpm run test` passes for the package.
- A keyless snapshot exercising `web_fetch` markdown rendering is added per testing policy (the missing snapshot coverage is part of the change, and it pins the new output).
-
-## Risks
-
- Model-visible output changes on every fetched HTML page — transcript drift is acceptable pre-release, and nothing currently pins the old output.
- Dependency weight: turndown's one dependency (`@mixmark-io/domino`) is a ~200 KB DOM that would enter the single-file-executable closure if tool-web ships in it ([single-exe note](../../implemented/architecture/2026-07-10-single-file-executable-sdk-runtime-distribution.md)); the minimal `entities` variant avoids this if closure size is the deciding factor.

-`packages/web/tool-web/src/html.ts`（约 86 行，另有约 40 行专属测试）用正则表达式把抓取到的 HTML 转成 markdown：剥离 script、style、noscript 标签与注释，转换 `<a>`/`<h1-6>`/`<li>`，解码数字实体外加一张 12 项的命名实体表，并折叠空白。该模块自身的 JSDoc 写明「A richer converter can replace it without changing the seam or tool schema」，README 的 Known Limitations 章节也把它记载为「a minimal regex converter, not an HTML parser — tables, images, and nested formatting are lost」。[web 能力 seam 决策记录](../../implemented/architecture/2026-06-24-web-capability-seam.md)把 HTML 转 markdown 作为呈现职责划归本包（package），因此替换点恰好就在这里。每个抓取到的 HTML 页面上，该转换器的输出都对模型可见；当前没有任何无密钥快照执行到 `web_fetch`，因此没有预期输出固定它的行为。
-
-## 提案
-
-用 `turndown` 替换 `htmlToMarkdown`（`new TurndownService().turndown(html)`），可选择配合 `turndown-plugin-gfm` 支持表格。`fetch.ts` 中的消费方分支与状态头、截断页脚的格式化保持不变。把调用包在 try/catch 中，失败时回退到原始文本路径：正则版本从不可能抛异常，而 turndown 处理病态 HTML 时可能抛出。删除 `html.ts` 及其转换测试；保留回退路径与外围格式化的测试。更新 README 的 Known Limitations 章节，移除正则转换器的警示说明。
-
-如果更倾向于「刻意保持最小回退实现」的立场，最小变体仍能删掉最糟的部分：用零依赖的 `entities` 包（已通过传递依赖存在于 lockfile 中）替换文件中占三分之一的实体解码部分（约 30 行：`decodeEntities`、`NAMED_ENTITIES`、`safeFromCodePoint`），以近乎为零的风险抹掉文档记载的「about a dozen entities」限制。
-
-## 曾考虑的替代方案
-
- **`@mozilla/readability` 加一个 DOM。** 它解决的是另一个问题（内容提取，而非格式转换），还会拖入更重的 DOM 依赖；这个 seam 只要求把抓取返回的内容渲染成 markdown。
- **保留正则转换器。** 按其自身 JSDoc 的说法，它本来就是明确的 v1 占位实现；保留它意味着模型可见的质量（表格、图片、嵌套格式）继续缺失，代价还是维护一套自制实体表。
- **仅引入 `entities` 的最小变体。** 已作为退守方案保留在提案中；它删得更少，但完全避开了依赖体积问题。
-
-## 验收标准
-
- `web_fetch` 经由 turndown 渲染表格与嵌套格式（或在最小变体下：解码全部命名实体），README 中的限制说明同步更新。
- 单元测试覆盖回退路径；该包的 `pnpm run test` 通过。
- 按测试政策补充一个执行 `web_fetch` markdown 渲染的无密钥快照（缺失的快照覆盖是本变更的一部分，它同时固定新输出）。
-
-## 风险
-
- 模型可见的输出在每个抓取到的 HTML 页面上都会变化：预发布阶段的 transcript（文本记录）漂移可以接受，且当前没有任何东西固定旧输出。
- 依赖体积：turndown 的唯一依赖（`@mixmark-io/domino`）是一个约 200 KB 的 DOM 实现，若 tool-web 进入单文件可执行文件，它会一并进入闭包（[single-exe 决策记录](../../implemented/architecture/2026-07-10-single-file-executable-sdk-runtime-distribution.md)）；若闭包体积是决定因素，最小的 `entities` 变体可以避开这一点。

 - **YAML consolidation (`js-yaml` vs `yaml`)**: the repo carries both parsers, with the `!!js` tag defined four times on js-yaml (vendored include, app-boot, apps/cli, `scripts/verify-cordis-config.ts`) and twice on `yaml` (sdk-telemetry's `ScalarTag`, sdk-helper's comment-preserving Document editing). The direction is forced — js-yaml cannot replace `yaml` (sdk-helper needs the Document API) — but migrating the js-yaml sites cannot retire the library either (the vendored include pins it) and would put two parsers in charge of one dialect that must agree exactly, against the [personal-config note](../../implemented/feature/2026-07-20-dsh-cli-personal-config.md)'s deliberate load-only-copy parity. Deletable: ~20–25 lines of duplicate tag definitions and two `@types/js-yaml` entries. The consolidation moment is a future include sync, not now.
