Enqueue separately carries the resolved `queued | steering` placement captured by the producer at acceptance time, so observers and reconnect mirrors never reconstruct routing from later status or session history. Injection never touches a FIFO and emits none of these. Every FIFO entry publishes an enqueue, including steering submitted by an `agent/turn-stopping` listener, so the ledger stays balanced with its later dequeue or discard. The `dsh-agent` invariant companion asserts FIFO conservation: a per-agent outstanding count that dequeue and discard can never drive negative. +**Inbox lifecycle events carry occurrence identities.** `agent/inbox/enqueue` (an item entered a FIFO), `agent/inbox/update` (a pending queued item was edited), `agent/inbox/dequeue` (the driver claimed one), and `agent/inbox/discard` (pending items were dropped) carry an `InboxItem`: an occurrence-local `InboxItemId`, the accepted `UserMessage`, and the resolved `queued | steering` placement captured at acceptance. The occurrence identity lets observers and reconnect mirrors distinguish repeated sends of the same `MessageId` without reconstructing routing from later status or session history. Injection never touches a FIFO and emits none of these. Every FIFO entry publishes one enqueue and exactly one terminal dequeue or discard; updates are non-terminal. The `dsh-agent` invariant companion asserts this FIFO conservation. **Admission accepts next-step input without becoming a turn.** The loop opens a private next-step acceptance window before `agent/prompt-submit`, keeps it open through the turn, and closes it before `turn/end`. Steering and injection received during admission therefore remain together in the outbox and join an allowed turn. If admission blocks or fails, a context-only caller batch takes idle injection's immediate append, while steering and context staged beside it remain available to retry; neither path writes the rejected prompt. When a later prompt is admitted, retained outbox input enters its turn before that prompt, while input accepted during the current admission remains after the prompt. Closing the window before `turn/end` preserves the rule that reentrant late steering becomes an independent queued turn. `Agent.acceptsNextStep` exposes whether a `next-step` send would currently join this window; `status` remains the broader activity signal rather than a routing predicate. -**One accepted message keeps one representation.** Durable user-role input and additional model-facing context both use `UserMessageData { content, source }` directly; public `AgentMessage` extends it with the correlation `id`, and the loop-private `PendingMessage` extends that with `wakeup`. The loop clones and freezes `UserMessageData` before publication, queueing, or immediate append, so later caller or observer mutation cannot change the accepted value. A queued message that becomes steering enters the outbox as the same `PendingMessage` object, while injected and tool-produced context enters as plain `UserMessageData`. The outbox therefore stores their union directly instead of wrapping steering beside a duplicate copy of its content and source. Provider-native assistant messages remain adapter-owned output types and do not participate in this input hierarchy. +**One accepted message keeps one representation.** Durable user-role input and additional model-facing context both use the identified, frozen `UserMessage` directly. The loop stores that value beside private routing state rather than copying its identity, content, or source into another public shape. A queued message that becomes steering keeps the same message value in the outbox, while injected and tool-produced context each carry their own identified message. The [identified immutable message decision](2026-07-28-identified-immutable-message-values.md) supersedes this note's former `UserMessageData`/`AgentMessage` hierarchy and extends the representation to assistant and tool-result messages. **Idle wakeup follows acceptance.** Before publishing enqueue, a waking queued send installs quiescence ownership and schedules driver admission for a microtask that runs after the id returns. Every send in one synchronous caller stack therefore resolves placement against the same pre-admission state, while reentrant cancellation or teardown cannot retire before the scheduled admission settles.

One durable message type serves prompts, injected context, and goal rounds, so the surface projection and every "human prompt?" check simplify to a `source` test. The `Agent` contract remains an interface, so alternate implementations and object-literal test fakes implement the same minimal structural surface.

Direct project references from `tsconfig.host.json` and `tsconfig.client.json` determine a package's face membership, while `package.json#exports` defines its public boundary. Cross-face relationships come only from explicit imports or re-exports in source and remain separate links; external npm types are recorded as External without reading or copying their declarations. + +PackageModel recognizes Cordis services, events, `@typert object` reference objects, and `@typert schema` data roots. Services and objects expose only public instance members, excluding constructors and static, private, and protected members; inheritance edges remain in TypeGraph instead of being copied into flattened members. When a public property, parameter, or return type lacks an annotation, `check` mode reports an error, while `write` mode writes the checker-inferred result, rebuilds the project, and analyzes it again in strict mode. + +[`dsh-typert-registry`](../../../../packages/typert/registry/README.md) provides `ctx.typert` and handles runtime registration only: one contribution atomically carries package-face reflection and an optional Zod schema, and Cordis effect disposal revokes it. The registry neither analyzes TypeScript nor merges the two faces. JSON Schema is an on-demand projection of registered Zod schemas. + +Package artifact publication is explicit opt-in. When invoked, `WorkspaceTypertGenerator` validates that each requested host face exposes the user-facing subpath `package/typert` from the root artifact `package/lib/typert.host.{js,d.ts}`, or that each requested client face exposes `package/client/typert` from `package/lib/typert.client.{js,d.ts}`. It neither edits exports nor runs as part of the ordinary root build or typecheck, so those commands do not generate whole-workspace Typert artifacts. Generated declarations keep `TYPERT` typed as `unknown`, so business packages do not depend on the registry. + +At build time, `CordisCatalogProjector` consumes the analyzed `FaceModel` and `TypeGraph` once to generate `docs/cordis-catalog/events.md`, `docs/cordis-catalog/services.md`, and the static `SERVICE_API`, `EVENT_API`, and `TYPE_API` catalog committed for `tool-cordis`. `tool-cordis` reads that static catalog and has no runtime dependency on `ctx.typert`. [`dsh-typert-loader`](../../../../packages/typert/loader/README.md) and the registry remain an independent runtime path: the loader follows Cordis Loader entry lifecycle events, imports an explicitly published `./typert` host artifact, and registers it through `ctx.typert`; neither component supplies the current `cordis_inspect` catalog. + +## Verification contract + +A small two-face project in the repository snapshots the complete type model, including its source declaration index. Batched workspace analysis and direct focused analysis must produce model-equivalent `FaceModel` and `TypeGraph` results for the same faces. Compile-time exhaustive maps and runtime set comparisons ensure that every node, target, declaration, and member discriminant is exercised by source-authored TypeScript syntax; a field-semantics matrix covers every keyword, type operator, and literal value category, plus every state of generics, parameters, tuples, mapped modifiers, import attributes, abstract forms, predicates, and enum initializers. + +For every property in `SyntaxZoo`, the TypeScript printer normalizes the source type, which must exactly match the TypeGraph rendering; TypeScript then recompiles every rendered declaration. This layer checks that each node's internal information is preserved losslessly, including no-substitution template literals, type queries with type arguments, and constrained `infer`, without substituting discriminant coverage or code coverage for structural equivalence. + +Boundary cases pin explicit package imports within and across faces, cross-face named re-exports, exact export aliases, qualified `import()` links, and the External classification of global `@types` declarations; they reject TypeScript diagnostics originating in package-owned files, relative-path boundary crossings, references outside `package.json#exports`, and cross-face namespace re-exports without a model target. Interface declaration merging explicitly preserves every authored part; other merges that cannot be represented losslessly fail. + +For each supported node kind and literal category, Zod emitter tests run both successful and failing parses; for each unsupported kind, they assert an explicit `TypertEmitError`. Emitter fixtures snapshot generated Zod JavaScript and `.d.ts` text, execute the JavaScript, and typecheck the declarations. `dsh-typert-registry` tests pin atomic registration, queries, JSON Schema, and effect disposal; `dsh-typert-loader` tests also prove delayed mounting, unloading, and disposal while a dynamic import remains pending. A real `dsh-tools` vertical slice generates a contribution from the model, loads it through the runtime registry, and compares its service, event, and related-type records with the committed static `SERVICE_API`, `EVENT_API`, and `TYPE_API`. A full-workspace projector test regenerates the two Cordis catalog documents and the `tool-cordis` API catalog and requires all three texts to be byte-for-byte identical to the committed artifacts. + +## Alternatives considered + +**Retain the TypeScript AST directly.** The AST preserves source syntax, but it would make every consumer depend on the compiler lifecycle, node identity, and checker context, preventing a stable architectural boundary. It is therefore used only during extraction. + +**Generate final types from the checker.** A flattened `ts.Type` is easy to traverse directly, but it loses the developer's expression of generics, conditional and mapped types, and alias applications, so it cannot support reflection and later generation needs. + +**Merge the host/client projects or duplicate host types.** Merging would contaminate Cordis declaration merging; duplication would create a second source of truth for types. Independent faces with explicit cross-face links preserve project isolation and actual reference relationships. + +**Make `dsh-typert-registry` responsible for type resolution and cross-package composition.** That would recouple the TypeScript compiler, Cordis lifecycle, and a specific schema policy. The registry remains a lifecycle container for generated artifacts, while the build-time model retains complex analysis. + +## Consequences + +New generation targets and static checks can reuse the same TypeGraph, and business categories can extend PackageModel without parsing the AST again. Preserving pre-evaluation types and independent faces makes the model more complex than a flattened schema; emitters must explicitly declare their supported scope and fail on missing capabilities. + +Explicit opt-in keeps artifact publication and package exports under package ownership, while ordinary root builds and typechecks incur no whole-workspace Typert generation phase. The static Cordis catalogs remain reproducible from the canonical model without coupling `tool-cordis` to runtime registry state. `ctx.typert` reflects only artifacts mounted in the current runtime, and unloading does not control Zod instances that consumers retain after importing them directly. diff --git a/.agents/notes/implemented/architecture/2026-07-27-compiler-independent-typert-model.zh.md

A browser turns the operator into a confused deputy against such a local API in two classic ways: a malicious page fires a "simple" cross-site POST (`text/plain` — sent without a CORS preflight) whose side effects execute even though the response stays unreadable, and a DNS-rebound origin talks to the socket as if same-origin, making CORS inapplicable entirely, with only the `Host` header betraying the attacker's domain. Before this decision the system's only browser-trust check (`isTrustedNativeDialogRequest`: loopback socket + same-origin + loopback Host) guarded exactly one cosmetic route — `host.pickDirectory`, whose native dialog pops on the host's screen — while every consequential method was unguarded.

Deliberately no shortcut for unmarked requests: over plain HTTP a browser attaches neither `Origin` nor Fetch-Metadata to reads (EventSource, images, navigations — those headers go only to trustworthy destinations), so an unmarked request may be a rebound browser read whose response the page can read, and Host is the one header rebinding cannot forge; non-browser clients pass via loopback, the derived LAN IP literals, or a declared authority. An attached `Origin` must equal the Host authority; `sec-fetch-site: cross-site` is refused outright.

The hidden phase therefore removes only tool traffic. + +**Keep resume restricted to one workspace or infer cwd after boot.** Rejected: the restriction forces manual relaunch, while restored header cwd does not control filesystem and shell resolution. The target directory must cross the host seam before process replacement. + +**Drop the TUI exit pill or remove model-facing exit markers.** Rejected: the pill is the scannable UI status, while the text marker is the model's status signal. The presenter consumes the marker when constructing the structured view so both audiences receive one representation. + +## Consequences + +The transcript reads as colored status headers over recessed detail, context presentation is stable for arbitrary prose, and one shortcut controls transcript density. The public `TuiTheme.muted` role is removed; extensions use `dim`. The palette and `renderUnknownXml` contracts are stricter, adding small compile-time friction in exchange for preventing silent style loss. + +Cross-workspace resume can move every path-resolving tool to another directory. A missing or inaccessible cwd prevents handoff. The broader picker also makes concurrent access to a shared session store easier to reach; cross-process session locking remains separate work. + +The terminal presenter still treats a final output line exactly matching its exit-marker grammar as structured status, so a command that intentionally prints such a line can lose it from the card body. This residual is documented by `dsh-tool-bash`. + +## Testing + +TUI unit and keyless terminal snapshots cover palette enumeration, light/dark roles, legal and illegal style composition, uniformly dim card bodies, semantic diff colors, marker-free terminal output with one exit pill, prose-preserving context frames, content-independent folding, the three-state Ctrl+O cycle, model filtering, and both resume scopes. CLI handoff tests cover passing the re-read cwd and rejecting directory-entry failure before teardown.

That shape cannot serve remote deployments — no OS dialog reaches a browser on another machine — and the planned in-app directory browser (Figma `Harness` 802-56979) needs listing/creation primitives, which are a different interaction contract, not a different implementation of the same one. Swapping interactions required editing gateway source, against the repo's everything-is-a-plugin stance. + +## Decision + +A three-package capability seam in `packages/host/` — `directory-picker` (interface), `directory-picker-native`, `directory-picker-browse` (backends) — with one contract method: `capability()` returns a **discriminated union**, `{ kind: 'native', pick(signal) }` or `{ kind: 'browse', list(path?), createDirectory(path, name) }`. The gateway (`dsh-host-apiproxy`) injects `directoryPicker`, serves the matching RPCs, and answers `directory-picker-unavailable` for the other kind. The union is discriminated because the backends differ in *interaction shape* — flattening them into one method set would force every backend to fake the other's shape. + +**The client side is slot-composed, not advertisement-branched.** ui-workspace's two trigger surfaces each declare a `single` directory-flow hole (`conversation.hero.workspace.directoryFlow` / `sidebar.workspaces.directoryFlow`; two keys because a hole has exactly one declaring slot entry — same owner contract, same occupant). Backend packages are **dual-face**: the browser half registers the matching interaction into both holes — `-native` a renderless occupant driving `host.pickDirectory`, `-browse` the in-app Select Workspace Directory dialog. The hole's owner conversation (`open`/`busy`/`onPicked`/`onCancel`/`onError`) carries the whole exchange: ui-workspace keeps the trigger (menu entry rendered only while the hole is occupied) and the adoption (`createWorkspace({path})`, conflict/error dialog, Choose again), the occupant owns everything between `open` and the picked path. One `cordis.yml` row therefore swaps the host capability and the client flow together; a mismatch is impossible by construction, and mounting two flow packages fails at client load (`single` hole). The earlier `host.describe.directoryPicker` advertisement and the client's kind branching are deleted — with composition wiring both sides, a wire fact for the client to branch on had no remaining consumer. The hole registry (`ctx.slots.entries`) replaces it as the per-menu-open occupancy read. + +Placement and policy rulings folded into this decision: + +- **Not the `ctx.fs` seam.** `packages/fs/` is the model/session-facing storage stack (policy events, sandbox-swappable backends). Riding it would couple GUI browsing to the model's confinement backend — swapping `fs-sandbox` for the model must never change GUI behavior — and OS facts (home anchoring, hidden conventions) are not storage primitives. The picker seam stays presentation-free and model-free; `packages/host/` is its consumer-domain home. +- **Dependency survey (hand-roll vs adopt).** Node's stdlib *is* the maintained cross-platform OS layer (`readdir(withFileTypes)`, `homedir`, path semantics); surveyed alternatives fail the dependency bar — file-manager packages (`node-file-manager`, `files-and-folders`, Syncfusion's provider) are whole HTTP apps (fit), drive-letter helpers (`drivelist` native addon, `windows-drive-letters` ~7y stale) fail health/proportionality. The browse backend is a thin adapter over stdlib. +- **Hidden entries: return-and-flag.** The host stamps `hidden` (POSIX dot convention) and returns everything; the client filters. Display policy stays client-side, and the show-hidden toggle shipped as exactly that client-only change: a fixed-label footer toggle whose state lives in the pressed presentation (`aria-pressed` + check glyph), a dot-led path-draft prefix reveals the hidden entries it names, and the current selection is exempt from both the hidden and the prefix filter (it anchors the two-pane view). Windows' `FILE_ATTRIBUTE_HIDDEN` is not exposed by dirents — documented limitation until a native probe pays for itself. +- **Path-editor cancel scope: the dialog card.** The browse client's path editor cancels on Escape and on focus leaving the card, both observed at a card-scope wrapper rather than the input — after Tab parks focus on a filtered row the input is off the event path, yet Escape must collapse the editor (not the dialog) and a later focus departure must still cancel. Non-cancel exemptions: window/tab focus loss, in-card focus moves, and pointer paths (rows and the toggle suppress focus steal on mousedown while editing). Separators for seeding and draft-tail filtering are inferred from `listing.home`; the wire-field alternative below records the deferred authoritative form. Combobox semantics between the editor and the list it filters (`aria-expanded`/`aria-controls`/active-descendant, result announcements) are likewise deferred — today they read to assistive tech as separate widgets. +- **Navigation lands selection-anchored, quiet, and bounded.** Away from the display root (the same collapse the crumb header renders, so crumbs and pane shape never disagree), the landing is two-pane: the target's actual parent-level entry re-selected (platform case folding on Windows), its children on the right, so a crumb jump reads as stepping back one pane rather than collapsing to a single column. Target and parent legs land as **one frame** when the parent leg settles within the 200ms wait bound — the stale view keeps rendering until then, so navigation swaps the panes without an intermediate single-pane flash — and past the bound the target commits alone at once (an Enter-submitted navigation is never held hostage by a stalled parent) with the late parent leg upgrading the landing in place. The parent leg runs under the landing's supersession scope and is aborted on the wire by any newer intent (Escape inside the landing window therefore withdraws the whole navigation); a failed parent leg, or a truncated parent window lacking the target, leaves the single-pane landing — the upgrade must never orphan the selection it exists to anchor. The loading indicator follows the same quiet rule: it floats over the content's bottom-right corner (never a layout-shifting row; the truncated/error rows own the bottom left and keep rendering through a scan) and only once a scan outlives a 300ms silence window, so a local listing swaps with nothing shown at all. Row picks are deliberately exempt from the one-frame rule: a pick's immediate pane split is its selected-state feedback (aria-current, crumbs following), while a navigation has nothing to acknowledge the click but the swap itself. Both timing constants are calibrated for local enumeration; a remote deployment (one RPC per level, commonly 100–400ms) would sit inside the silence window with no pressed state on the crumbs — revisit the window or add pressed feedback when a remote consumer lands. +- **Symlinks: follow for enterability.** `stat` probes symlinks (broken/cyclic → skipped); crumbs keep the logical path the operator navigated, and `workspace.create` already canonicalizes via realpath at adoption. +- **Listing levels are bounded, and streamed.** One `list` call returns at most `maxEntries` rows (config, default 1000 — GitHub's web-UI directory-listing bound). The level streams via `opendir` into a name-sorted window of `maxEntries + 1` candidates, so memory stays O(maxEntries) and enterability probing touches only windowed candidates; the wire `DirectoryListing` carries a required `truncated` flag so the client states incompleteness instead of silently missing tail entries. A windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated. Window insertion is binary with an O(1) full-window tail rejection (an oversized level must not pay a window scan per dirent), and `list(path, signal)` threads the carrier's request signal so a scan of a stalled network directory cannot outlive a disconnected caller — every await in the scan (open, each read, each symlink probe) races the signal, an aborted exit abandons rather than awaits the close (Node queues close behind in-flight reads), and abandoned settlements are swallowed so cleanup can never surface as an unhandled rejection. An unbounded level is a memory/responsiveness hole for large or adversarial directories. +- **Whole-filesystem scope, no roots config.** `workspace.create` accepts arbitrary paths and the API serves bash-driving methods, so a browse root would be UX scoping, not a boundary; configurability without a consumer fails the evidence bar. Deferred until a deployment needs it. +- **The native backend stays.** Plugin-form was the point: multiple providers can serve the seam (an Electron shell would provide the `native` interaction through its own dialog API). Kind naming: `dialog` was the first pick and was dropped — the browse interaction also presents a dialog (the in-app modal), so the word failed to discriminate; `native` names where the chooser runs. + +## Alternatives considered + +- **Extend `ctx.fs` with browse methods.** Rejected: authority-domain coupling above; also a listing-for-display contract (hidden flags, crumbs, home anchor) does not belong on a storage seam. +- **One uniform seam method set (`pick(): path`).** Rejected: an in-app browser cannot be served behind a single host-side call — the browsing loop lives in the client and needs primitives on the wire; the native chooser cannot implement primitives. The interaction difference is irreducible, hence the discriminant. +- **Direct stdlib calls inside apiproxy (no seam).** Rejected: keeps the gateway the only swap point (source edits), loses fixture/test backends, and contradicts the plugin doctrine that motivated the work. +- **Adopting a file-manager/drive-enumeration dependency.** Rejected per the survey above; recorded here as the dependency policy requires. +- **A flip-label show-hidden toggle ("Hide hidden files").** Rejected: a flipping action label is ambiguous between state and action and doubles the negative; the fixed label with a pressed presentation states both at once. +- **Pure relatedTarget blur cancellation (no mousedown suppression).** Rejected: Safari does not focus buttons on pointer down, so a click's focusout carries a null `relatedTarget` and would cancel the editor before the click lands; editing-scoped mousedown suppression plus the card-anchored relatedTarget guard covers pointer and keyboard paths together. +- **A wire `separator` field on `DirectoryListing` (host stamps `path.sep`).** Deferred, not rejected: it is the authoritative form — a POSIX home directory containing a backslash defeats the `listing.home` heuristic — but it touches the seam type and every backend; the browse client's `separatorOf` carries a TODO pointing at this alternative until a wire change is next scheduled. + +## Consequences + +- `cordis.yml` chooses the interaction; `apps/cli` mounts `-browse` (the shipped default — remote-capable picking out of the box), one row having swapped backend and UI together; `-native` remains the host-display alternative. +- The wire gains `host.listDirectory`/`host.createDirectory` and four error codes; the connection fixture serves a deterministic browse tree and a deterministic `pickDirectory` path for keyless assembled tests. +- A future interaction (or an Electron provider of the `native` interaction) is one dual-face backend package — no gateway surgery, no ui-workspace edits. +- `ApiProxyDefaults.pickDirectory` (test-only injection) is gone; tests provide a stub `ctx.directoryPicker` like any other service. diff --git

createDirectory(path, name) }`。网关（`dsh-host-apiproxy`）注入 `directoryPicker`，提供对应的 RPC，另一种 kind 的调用以 `directory-picker-unavailable` 应答。联合之所以可辨识，是因为后端差异在**交互形态**——压平成统一方法集会逼每个后端伪装另一方的形态。 + +**client 侧靠 slot 组合，而非按广播分支。** ui-workspace 的两个触发表层各自声明一个 `single` 目录流洞（`conversation.hero.workspace.directoryFlow`／`sidebar.workspaces.directoryFlow`；之所以是两个 key，是因为一个洞只有一个声明它的 slot entry——owner 契约相同、占用者相同）。后端包是**双面包**：browser half 把匹配的交互注册进两个洞——`-native` 是驱动 `host.pickDirectory` 的无渲染占用者，`-browse` 是应用内的选择工作区目录对话框。洞的 owner 会话（`open`/`busy`/`onPicked`/`onCancel`/`onError`）承载整个交换：ui-workspace 保留触发（菜单入口仅在洞被占用时渲染）与接纳（`createWorkspace({path})`、冲突／错误对话框、重新选择），占用者持有从 `open` 到所选路径之间的一切。因此一行 `cordis.yml` 同时切换宿主能力与 client 流程；错配在构造上不可能，同时挂两个流程包会在 client 加载期失败（`single` 洞）。早先的 `host.describe.directoryPicker` 广播与客户端 kind 分支被删除——组合已经接好两侧后，供客户端分支用的 wire 事实不再有任何消费者。洞注册表（`ctx.slots.entries`）取而代之，成为每次打开菜单的占用读取。 + +并入本决策的位置与策略裁决： + +- **不用 `ctx.fs` seam。** `packages/fs/` 是面向模型／会话的存储栈（policy 事件、sandbox 可换后端）。骑上去会把 GUI 浏览耦合进模型的限制后端——为模型换 `fs-sandbox` 绝不能改变 GUI 行为——而 OS 事实（home 锚定、隐藏约定）也不是存储原语。picker seam 保持无展示、无模型；`packages/host/` 是它消费方域的家。 +- **依赖调研（手写 vs 引入）。** Node 标准库本身就是维护中的跨平台 OS 层（`readdir(withFileTypes)`、`homedir`、路径语义）；调研过的替代品都过不了依赖门槛——文件管理器包（`node-file-manager`、`files-and-folders`、Syncfusion 的 provider）是整套 HTTP 应用（契合度不过），盘符工具（原生插件 `drivelist`、约七年未更的 `windows-drive-letters`）健康度／比例失当。browse 后端是标准库上的薄适配。 +- **隐藏条目：返回并打标。** 宿主标注 `hidden`（POSIX 点前缀约定）并返回全部条目；客户端过滤。展示策略留在客户端，"显示隐藏"开关正是作为这一纯客户端改动落地：标签固定的 footer 开关，其状态由按下态呈现承载（`aria-pressed` + 勾选符号）；以点开头的路径草稿前缀会显出它所指名的隐藏条目；当前选中项则不受隐藏与前缀两种过滤影响（它锚定着双栏视图）。Windows 的 `FILE_ATTRIBUTE_HIDDEN` 不被 dirent 暴露——记为限制，直到原生探测值回其成本。 +- **路径编辑器的取消范围：对话框卡片。** browse 客户端的路径编辑器在按 Escape 与焦点离开卡片时取消，两者都在卡片范围的包装层而非输入框上监听——Tab 把焦点停到某个过滤命中的行之后，输入框已不在事件路径上，但 Escape 仍须收起编辑器（而非对话框），其后的焦点离开也仍须取消。不取消的豁免：窗口／标签页失焦、卡片内焦点移动，以及指针路径（编辑期间行与开关在 mousedown 时抑制焦点夺取）。预填与草稿末段过滤所用的分隔符从 `listing.home` 推断；下文的线上字段替代方案记录了被延期的权威形态。编辑器与其过滤的列表之间的 combobox 语义（`aria-expanded`／`aria-controls`／active-descendant、结果播报）同样被延期——目前二者在辅助技术看来是彼此独立的控件。 +- **导航以选中项为锚、安静且有界地落地。** 在展示根之外（与 crumb 头部渲染的是同一塌缩，因此 crumb 与分栏形态永不相左），落地即双栏：重新选中目标在父层级中的实际条目（Windows 上按平台惯例折叠大小写），右侧展示其子项，因此 crumb 跳转读作后退一栏，而不是塌缩成单列。父层级这一程在 200ms 等待上限内落定时，目标与父层级两程以**同一帧**落地——在此之前陈旧视图持续渲染，导航换栏时因此没有中间的单栏闪现——超出该上限则目标即刻单独提交（Enter 提交的导航绝不会被滞塞的父层级扣作人质），迟到的父层级这一程再就地升级这次落地。父层级这一程在落地的 supersession 范围下运行，任何较新的意图都会在线上将其中止（因此在落地窗口内按 Escape 即撤回整次导航）；父层级这一程失败，或被截断的父窗口缺少目标时，都保留单栏落地——升级的存在正是为了锚定选中项，绝不能反而让它悬空。加载指示器遵循同一安静规则：它浮于内容右下角（绝不是会挪动布局的一行；截断／错误行占据左下角，并在扫描期间持续渲染），且仅在扫描超出 300ms 静默窗口后才出现，因此本地列举切换时什么也不显示。行选取被刻意豁免于同一帧规则：选取后立即分栏本身就是其选中态反馈（aria-current、crumb 跟随），而导航除了换栏本身没有任何东西可确认这次点击。两个时序常量都按本地列举校准；远程部署（每层级一次 RPC，通常 100–400ms）会落在静默窗口之内、crumb 上却没有按下态——待远程消费方落地时，重新审视该窗口或补上按下反馈。 +- **符号链接：为可进入性而跟随。** 用 `stat` 探测符号链接（断链／循环→跳过）；面包屑保留操作者导航的逻辑路径，`workspace.create` 在接纳时本就做 realpath 规范化。 +- **列举层级有上限，且流式处理。** 单次 `list` 至多返回 `maxEntries` 行（配置项，默认 1000——GitHub 网页端目录列举的同一上限）。层级经 `opendir` 流入一个按名排序、容量 `maxEntries + 1` 的候选窗口，内存保持 O(maxEntries)，可进入性探测只触及窗口内候选；线上 `DirectoryListing` 携带必填的 `truncated` 标志，让客户端明示不完整而不是静默缺尾。窗口内的断链符号链接不从窗口外回填——发生过驱逐本身已把层级标记为截断。窗口插入为二分查找、满窗尾部单次比较即拒绝（超大层级不能为每个 dirent 付出一次全窗扫描），且 `list(path, signal)` 透传载体的请求信号，滞塞网络目录的扫描不会在调用方断连后继续存活——扫描中的每个 await（打开、每次读取、每次符号链接探测）都与信号赛跑，中止路径放弃而非等待 close（Node 会把 close 排在在飞读取之后），被放弃的 settlement 全部吞掉，清理不会以未处理拒绝的形式冒出。无上限的层级对超大或恶意构造的目录就是内存／响应性漏洞。 +- **全盘可浏览，不做 roots 配置。** `workspace.create` 接受任意路径且 API 本就提供驱动

The Cordis-config declaration gate (`verify-cordis-config`), the app-boot fail-loud plugin diagnostic, and the vendored `import type` marks remain current. + +## Problem + +The `dsh` source entry point originally used `tsx` to run `apps/cli/src/bin.ts`, with the same third-party loader implicitly handling both TypeScript transformation and the root tsconfig's `paths` resolution. With Node handling TypeScript natively, it does not apply tsconfig path mappings; resolving through package exports would instead mix potentially stale or nonexistent `lib/` artifacts into the source launch. + +Node's transform also does not perform type analysis.

The source graph therefore has to use explicit type-only imports and native ESM exports; a resolve hook cannot repair incompatible source syntax. + +Cordis configuration introduces a separate resolution boundary. Bare plugins in `cordis.yml` do not pass through TypeScript import analysis, so their resolver manifest may omit the required dependencies.

Test and E2E launchers retain their existing strategies, and the built `lib/bin.js` continues to run under ordinary Node. + +`scripts/tspath-loader.ts` registers only a module resolve hook. It uses `TSX_TSCONFIG_PATH` when set (resolving relative values from the invoking cwd) and otherwise reads the root `tsconfig.json`; `TsconfigPathsResolver` follows that config's `extends` chain through the repository's existing TypeScript development tool, selects exact or wildcard `paths` entries according to tsconfig rules, and maps matching workspace bare specifiers to `.ts`/`.mts`/`.cts` source files or directory index files. Node remains solely responsible for code transformation. The source-only loader is not part of the built CLI and `apps/cli` does not declare `typescript` as a runtime dependency. + +Source imports are redirected only when the target package is either the nearest package manifest's own name or one of that manifest's declared runtime dependencies. The Cordis Loader uses the configuration directory URL as the import parent; the resolver then searches upward for the workspace manifest that declares the plugin, so dependency ownership for the shipped `apps/cli/config/base.cordis.yml` plus its surface overlay lies with `apps/cli/package.json`. Specifiers that do not match tsconfig paths, refer to undeclared dependencies, or are not bare all fall back to Node's default resolution. + +`verify-cordis-config` performs a one-way completeness check on the resolver manifest: every bare plugin package in a configuration must appear in the corresponding manifest's `dependencies`, while the manifest may contain extra dependencies not referenced by that configuration. The root `AGENTS.md` makes updating the configuration and dependencies together a standing rule. + +After the Loader settles, the shared `dsh-app-boot` checks every enabled entry that has no fiber and rejects startup with `plugin(s) failed to load: ...; Cordis startup failed because these plugin(s) could not be resolved`, listing all failed plugins. This diagnostic lives at the app layer and does not change the vendored Loader's startup behavior. + +Node-compatible TypeScript is part of this source-launch contract. Vendored Cordis, Loader, Include, HMR, and Schemastery mark erased imports with `import type`. Schemastery uses a native ESM default export and declares `type: module`; its `.mjs` and `.cjs` build outputs retain the existing ESM-default and callable-`require()` behavior. These divergences are recorded in `vendor/README.md`; no runtime behavior is added to the vendored frameworks. + +## Alternatives considered + +**Continue using `tsx`.** Rejected because `tsx`/esbuild would continue to own TypeScript transformation, so this launch chain could not prove that Node's native transformation works. + +**Load the built `lib/` through package exports from the source entry point.** Rejected because this would mix the source plane with the artifact plane; a zero-build development launch could read stale artifacts or fail outright. + +**Apply the root tsconfig `paths` unconditionally.** Rejected because this would allow undeclared cross-package imports and Cordis plugins to keep resolving, hiding mismatches between the manifest and the actual runtime graph. + +**Transform imports inside the custom loader.** Rejected because type-aware source rewriting would reintroduce a compiler-style transform and make the loader, rather than Node, responsible for TypeScript execution.

Agent input acquired an inbox correlation id only when the loop accepted it, while durable user messages, assistant messages, tool results, and model-request messages could have no identity. Prompt admission therefore sat between creation and identity, and equivalent content was copied across live events, durable events, and model requests without one value that named the message throughout its lifetime. + +This made identity a routing side effect rather than a message invariant. Producers could not refer to a message before calling the agent, prompt hooks received content and source separately, and later projections had to reconstruct a message while deciding whether an id existed. Immutability also began at different boundaries: some inputs were frozen by the loop, some only by session append, and provider-produced assistant output used a separate provenance-bearing shape. + +## Decision + +`@deepseek-ai/dsh-llm` owns one `Message` value with required `id`, `role`, `content`, and `source`. `MessageId` is opaque and shared by user, assistant, and tool-result messages. A message receives its id at creation, before routing, prompt admission, durable append, or request projection. The same id survives every representation boundary. + +`createMessage(input)` is the canonical role-generic creation boundary. It mints a `MessageId`, detaches the supplied role, content, and source, and deep-freezes the complete value before returning it. `createUserMessage({ content, source })` fixes the user role for prompt and context producers. `createAssistantMessage({ content, source })` fixes both the assistant role and the model source kind, so model-output producers supply only content and model provenance. All creation helpers exclude an input id so callers cannot accidentally present creation as import. `freezeMessage(message)` is the separate import or transformation boundary: it detaches and deep-freezes a message whose identity already exists, without minting a replacement. + +The helpers live in `dsh-llm` beside the base message vocabulary because their complete contracts depend only on that vocabulary. `createToolResultMessage()` belongs with the other creation helpers: it couples a tool call id to the exact user-role tool-result block and source without depending on session state or events. `dsh-session` consumes complete messages rather than owning their construction. + +The `Agent` interface accepts a complete `UserMessage`. `send`, `followup`, `steer`, and `inject` never allocate or return identity; they freeze an imported value whose id the caller already holds. Prompt admission receives that message directly. A content rewrite creates a frozen replacement with the same id, while an additional context is a separately created `UserMessage` with its own id. + +Durable message-producing events store complete messages. `user/message` stores its `UserMessage` directly; `assistant/message`, `tool/result`, and `steering/message` wrap their role-specialized message beside event-local position, usage, failure, or presentation facts. Session derivation returns those frozen values instead of reconstructing anonymous messages. Assistant assembly creates a model-sourced message when a response completes, and tool execution creates a tool-sourced message when a result is committed. + +Any operation that changes only the representation of an existing semantic message preserves its id and returns another frozen value. An operation that creates a new semantic message mints a new id. Compaction content rewrites therefore preserve the rewritten tool-result identity, while a summary checkpoint is a new message. + +## Alternatives considered + +**Keep ids optional on the base message.** This would minimize fixture migration and allow provider or persistence shapes to remain anonymous. It would also preserve the original ambiguity: every consumer would need to branch on whether identity exists, and no type would prove that admission, logging, or projection retained it. + +**Let `Agent.send()` allocate the id.** This keeps identity scoped to inbox correlation but makes the agent call the earliest point at which a producer can name its own message. Prompt construction, UI attachments, and synchronous enqueue/discard coordination then need content matching or an out-of-band token before `send()` returns. + +**Let each durable event allocate a new id.** This gives persisted messages identities but deliberately breaks correlation with the live input and makes replayed requests appear to contain different messages. Identity belongs to the semantic value, not to each envelope that carries it. + +**Freeze only at agent or session admission.** This avoids a creation helper but leaves an identified mutable interval in which caller code can change the meaning associated with an id. The decision makes “has an id” and “is an immutable snapshot” coincide. + +## Consequences + +Every message producer must choose creation or import explicitly, and tests construct complete values rather than partial content/source records. UUID generation moves outward to the first semantic creation point, so deterministic fixtures that provide an existing id use `freezeMessage()` instead of `createMessage()`. + +Live inbox events, durable events, derived history, and model requests can correlate one message without content equality or envelope-specific ids. Prompt admission and UI attachment cleanup can compare `MessageId` before a turn exists.

With them went the loader's runtime rule of mapping a workspace import only for declared runtime dependencies — tsx applies the `paths` map unconditionally. Declaration completeness now rests on the static gates alone: `verify-cordis-config` for configured bare plugins, and workspace constraints for manifests. (That runtime rule found real bugs: `dsh-plan-mode` and `dsh-tool-tasks` imported `@deepseek-ai/dsh-llm` while declaring it only in devDependencies; fixed alongside this change.) + +The node-compat CI matrix (Node 22.19 and 26) gains `dsh-source-launch-smoke` (`apps/cli/tests/source-launch.compat.spec.ts`): a keyless piped-stdio launch of the exact production vector asserting the non-zero-exit TTY refusal.

The owner must either refuse to compact a log that is actually free (wedging the session) or proceed over one that is genuinely busy. + +Nothing in the log marked where inherited history ended. `session/created`, `session/disposed`, and `session/flush` are cordis runtime signals, not log events; `agent/session-start` is emit-only. `Session.firstLiveSeq` already held the answer exactly — the seq of this lifecycle's first own write — but only in memory, so a consumer reading stored bytes could not see it. + +Crash repair does not close the gap and must not: `interruptedTurnClosers` synthesizes turn, step, and tool boundaries because core owns that vocabulary, and `compact/*` belongs to the compaction seam. A core repair pass that closed plugin brackets would put every plugin's bracket semantics in core. + +## Decision + +`Session`'s constructor appends the log-only `session/end-seed` event immediately after a non-empty constructor seed, as the seeded session's first live write at the seq `firstLiveSeq` names. The event is the durable projection of that field: `firstLiveSeq` answers where this lifecycle's writes start for a consumer holding the object, while `session/end-seed` answers the same question for one holding only stored bytes. Its payload is empty — position and `time` carry the whole meaning — and it is not a `SurfaceEventType`, so it produces no message and cannot perturb derived history. + +A bracket owner reads it positionally: an unmatched opening marker before `session/end-seed` has a smaller seq, came from the constructor seed, and belongs to a lifecycle that has ended. Core writes the boundary and reads nothing from it; each bracket's vocabulary stays with its owning plugin, so no core predicate helper ships without a consumer to shape it. + +The constructor is the placement because it is the single waist every seeded session passes through. All six entry points reach it: `agents.resume()`, config-driven startup on a persisted id (`restoreOrCreateConfigured`), `sessions.fork()`, a subagent fork child, `coordinator.adopt()`'s live-prefix path, and a bare `sessions.create(id, {seed})`. A boundary written at persistence load would miss both fork paths — and a forked child inheriting a still-running parent's open `compact/start` is precisely the case that must be classifiable. A boundary written at loop start would miss `fork()` and `adopt()`, and would have to fire on `SessionStartSource: 'startup'`, which is what a fork child publishes, so that field would stop discriminating. + +Two guards keep the marker from becoming noise. An empty seed writes nothing because there is no seed to end. A seed already ending in one is not re-marked, which makes the write idempotent. Idempotence is load-bearing rather than tidiness — `agentFor()` resumes a cold session on first touch, so merely opening one in a client is a pickup, and without the guard browsing would grow a log by one event per visit. + +## Persistence needs no changes + +The constructor append happens before `enter()`, so the session has no store attachment: the marker never publishes on `session/event`, exactly like the seed events before it. It is instead part of the log `initFor` captures as the creation seed, and persists through the ordinary seed path — `onCreated`'s `createCore` + `appendCore`, or the ownerless-claim suffix write. A consumer that watches the firehose therefore never sees the boundary and must read it from the log. + +Consequences for the seam: `load()` stays a pure read, with no revision bump, no `commitRepair` on a balanced log, and no durable mark left by a rejected `append`. **Attaching is not a pure read**, though — a pickup now writes where nothing was written before, so a read-only or full disk fails at `session/created` rather than at the first real turn. That is the one cost this placement adds, and it is narrower than the load-path version's (which failed the load itself). + +A crash before the seed write reaches disk loses the boundary, and that costs nothing: the pending batch is written in order, so a lost boundary means every event after it is lost too. The next pickup reads the same bytes the previous one did, appends its own boundary, and classifies the bracket identically. In-process consumers should prefer `firstLiveSeq`, which is exact before any write. + +## Scope of the guarantee + +The predicate holds for a bracket *this* session inherited, not as a liveness signal about other writers. A concurrently live session may hold an open bracket over the same stored history while its own boundary sits elsewhere. A consumer that must tolerate concurrent writers needs a liveness signal beyond the log and cannot omit it on the strength of this event. + +## Alternatives considered + +**A boundary written by the persistence coordinator's cold-load path.** Built first, as the [`session/resumed` boundary](../../rejected/architecture/2026-07-29-session-resumed-log-boundary.md), and abandoned before merge. It covers no fork, which is the one case where the inherited bracket's owner may still be running. Because the marker was minted at load it also had to be a durable write on a read path, which spread cost across the seam: a revision bump on every cold load, a `commitRepair` batch on a balanced log with nothing to repair, a stored-time floor to keep the clamp monotonic, and a load that failed against a read-only store. + +**A boundary appended at loop start.** The loop calls `resumeWith`, so it covers the resume paths, but it misses `fork()` and `adopt()` entirely, and the event would have to fire on `'startup'` — the source a fork child publishes — so `SessionStartSource` would stop discriminating. It also publishes the session before the marker is appended, so a `session/created` listener could observe a seeded log with no boundary. + +**Reusing `header.seedLength`.** It is the durable *fork-lineage* boundary and deliberately keeps the original fork value across a resume, where the constructor seed is the whole stored log. The two facts differ and conflating them would lose both. + +**Crash repair closing `compact/*` alongside turn boundaries.** Rejected: it moves every plugin's bracket semantics into core's repair pass, and core cannot know what closing another package's bracket should record. + +## Consequences + +Bought: one boundary, written in one place, correct for all six seeded-start paths — including the fork gap the persistence-layer version could not reach. The persistence packages keep a pure read path. `firstLiveSeq` gains a durable twin rather than a second, competing notion of the same boundary. + +Cost: a seeded session's log is one event longer, which moved seq expectations in tests across nine packages (session, agent-loop, persistence contract, jsonl, session-query, session-title, subagent-inprocess, telemetry, token-meter). Two of those updates are load-bearing rather than mechanical: telemetry's adoption tests now assert the boundary IS exported, because it is this lifecycle's own write, and the property suite's replay invariant is restated as "seed reproduced verbatim, plus one log-only boundary" with idempotence added as its own property. + +`session/end-seed` joins the on-disk vocabulary. Under the pre-release stance (`SESSION_FORMAT_VERSION` pinned at `0`, no compatibility promise) older logs simply lack it, and a log without a boundary correctly classifies nothing as constructor-seed history. + +Not built here: no plugin reads the boundary yet. Wiring the compaction seam's staleness check to it is the follow-up that motivated this boundary; the predicate helper belongs with that seam, where a real consumer decides its shape, rather than shipping into core untested against one. diff --git a/.agents/notes/implemented/architecture/2026-07-30-session-end-seed-log-boundary.zh.md b/.agents/notes/implemented/architecture/2026-07-30-session-end-seed-log-boundary.zh.md new file mode 100644 index 0000000000..33680c1845 --- /dev/null +++ b/.agents/notes/implemented/architecture/2026-07-30-session-end-seed-log-boundary.zh.md @@ -0,0 +1,55 @@ +# Agent Note: 种子结束日志边界 + +Status: implemented + +[English](2026-07-30-session-end-seed-log-boundary.md) | 中文 + +## Problem + +拥有独立开／闭括号的插件无法区分一个已死的标记和一个存活的标记。`compact/start` … `compact/end` 就是已发布的实例：当接手一份日志、而它最后的压缩事件是一个未配对的 `compact/start` 时，"上一个写入方在压缩中途死掉了"与"此刻正有一次压缩在运行"在存储历史中是逐字节相同的。所有方只能二选一：拒绝压缩一份其实空闲的日志（把会话卡死），或者在一份确实繁忙的日志上继续压缩。 + +日志中没有任何东西标出继承历史在哪里结束。`session/created`、`session/disposed` 与 `session/flush` 是 cordis 运行时信号，不是日志事件；`agent/session-start` 只发射不落盘。`Session.firstLiveSeq` 本来就精确地持有这个答案——本生命周期第一次自有写入的 seq——但只存在于内存中，因此读取存储字节的消费方看不到它。 + +崩溃修复既没有填上这个缺口，也不应该去填：`interruptedTurnClosers` 合成轮次、步骤与工具边界，是因为核心拥有那套词汇表，而 `compact/*` 属于压缩 seam。一个会关闭插件括号的核心修复流程，等于把每个插件的括号语义都搬进核心。 + +## Decision + +`Session` 的构造函数紧接非空构造种子之后追加仅日志事件 `session/end-seed`，作为带种子会话的第一次实时写入，位置正是 `firstLiveSeq` 指出的 seq。该事件是那个字段的持久投影：`firstLiveSeq` 为持有对象的消费方回答本生命周期的写入从哪里开始，`session/end-seed` 则为只持有存储字节的消费方回答同一问题。它的 payload 为空——位置与 `time` 承载全部含义——并且不是 `SurfaceEventType`，因此不产生消息，也无法扰动派生历史。 + +括号所有方按位置读取它：在 `session/end-seed` 之前的未配对开启标记具有更小的 seq，来自构造种子，并且属于一个已结束的生命周期。核心写入该边界但不从中读取任何内容；每个括号的词汇表仍归其所属插件，因此在没有消费方来塑形之前，核心不会先发布谓词辅助函数。 + +选择构造函数，是因为它是每一个带种子会话都必经的唯一收窄处。全部六个入口都会到达它：`agents.resume()`、在已持久化 id 上的配置驱动启动（`restoreOrCreateConfigured`）、`sessions.fork()`、子代理 fork 子会话、`coordinator.adopt()` 的实时前缀路径，以及裸的 `sessions.create(id, {seed})`。在持久化加载时写入的边界会漏掉两条 fork 路径——而一个继承了仍在运行的父会话开放 `compact/start` 的 fork 子会话，恰恰是必须可判定的场景。在 loop 启动时写入的边界会漏掉 `fork()` 与 `adopt()`，并且不得不在 `SessionStartSource: 'startup'` 上触发——那正是 fork 子会话发布的取值，于是该字段将不再具有区分力。 + +两条守卫让这个标记不至于变成噪声。空种子不写入任何内容，因为没有种子需要结束。种子本身已以该事件结尾时不会重复标记，这让写入具备幂等性。幂等性是承重的，而不是为了整洁——`agentFor()` 会在首次触碰时恢复一个冷会话，因此在客户端里仅仅打开一个会话就是一次接手；没有这条守卫，浏览会让日志每访问一次就增长一个事件。 + +## 持久化无需任何改动 + +构造函数中的 append 发生在 `enter()` 之前，因此会话尚无 store attachment：该标记不会在 `session/event` 上发布，与它之前的种子事件完全一样。它属于 `initFor` 捕获的那份创建种子，并通过普通的种子路径落盘——`onCreated` 的 `createCore` + `appendCore`，或无主认领的后缀写入。因此监听 firehose 的消费方永远看不到这条边界，必须从日志中读取它。 + +对 seam 的影响：`load()` 仍是纯读取，没有 revision 递增，对平衡日志不走 `commitRepair`，被拒绝的 `append` 也不留下持久标记。但**接手不是纯读取**——如今一次拾起会在此前完全无写入的路径上产生写入，因此只读存储或磁盘写满会在 `session/created` 处报错，而不是在第一个真实轮次处。这是本放置方式新增的唯一成本，并且比加载路径方案的成本更窄（后者会让加载本身失败）。 + +若崩溃发生在种子写入到达磁盘之前，边界会丢失，而这没有代价：待处理批次按序写入，所以丢掉一个边界意味着它之后的每个事件也一起丢掉。下一次接手读到的字节与上一次相同，会追加自己的边界，并对括号作出完全相同的判定。进程内消费方应优先使用 `firstLiveSeq`，它在任何写入之前就是精确的。 + +## 保证的适用范围 + +该谓词对*本*会话继承的括号成立，而不是关于其他写入方的存活信号。一个并发存活的会话可能在同一段存储历史上持有开放括号，而它自己的边界在别处。必须容忍并发写入方的消费方需要日志之外的存活信号，不能仅凭这个事件就省掉它。 + +## Alternatives considered + +**由持久化协调器的冷加载路径写入边界。** 最先实现的方案，即 [`session/resumed` 边界](../../rejected/architecture/2026-07-29-session-resumed-log-boundary.md)，在合并前被放弃。它完全覆盖不到 fork，而 fork 恰恰是继承括号的所有方可能仍然存活的那一种情形。由于标记是在加载时铸造的，它还必须在读取路径上做持久写入，这把成本铺开到整个 seam：每次冷加载都递增 revision、对一份无需修复的平衡日志也要走 `commitRepair`、需要一个已存储时间下限来维持钳制的单调性，以及加载在只读存储上会失败。 + +**在 loop 启动时追加边界。** loop 调用 `resumeWith`，因此覆盖恢复路径，但完全漏掉 `fork()` 与 `adopt()`，而且事件不得不在 `'startup'` 上触发——那是 fork 子会话发布的来源——于是 `SessionStartSource` 将不再具有区分力。它还会在追加标记之前就发布会话，因此 `session/created` 监听方可能观察到一份没有边界的带种子日志。 + +**复用 `header.seedLength`。** 它是持久的 *fork 血缘*边界，并且刻意在恢复时保留原始 fork 取值——而恢复时构造种子是整份存储日志。这两个事实并不相同，混同会同时失去两者。 + +**让崩溃修复连同轮次边界一起关闭 `compact/*`。** 否决：这会把每个插件的括号语义搬进核心的修复流程，而核心无法知道关闭另一个包的括号应该记录什么。 + +## Consequences + +买到的：一条边界，在一处写入，对全部六条带种子启动路径都正确——包括持久化层方案触及不到的 fork 缺口。持久化各包保留纯读取路径。`firstLiveSeq` 获得一个持久孪生体，而不是关于同一边界的第二套彼此竞争的概念。 + +代价：带种子会话的日志长了一个事件，这在九个包（session、agent-loop、持久化契约、jsonl、session-query、session-title、subagent-inprocess、telemetry、token-meter）里挪动了 seq 期望。其中两处更新是承重的而非机械的：telemetry 的收养测试现在断言该边界*会*被导出，因为它是本生命周期的自有写入；而属性测试套件的重放不变式被重述为"种子逐字节复现，外加一个仅日志边界"，并把幂等性补成一条独立属性。 + +`session/end-seed` 加入了落盘词汇表。在预发布立场下（`SESSION_FORMAT_VERSION` 固定为 `0`，不作兼容承诺），更旧的日志只是没有它，而没有边界的日志会正确地判定没有任何内容属于构造种子历史。 + +此处未做：还没有任何插件读取该边界。把压缩 seam 的陈旧性检查接到它上面，是催生这条边界的后续工作；谓词辅助函数应当归属那个 seam——在那里由真实消费方决定它的形状——而不是未经真实消费方检验就先落进核心。 diff --git a/.agents/notes/implemented/bug-fix/2026-07-28-load-pre-identity-session-messages.i18n.yaml b/.agents/notes/implemented/bug-fix/2026-07-28-load-pre-identity-session-messages.i18n.yaml new file mode 100644 index 0000000000..56832b37e2 --- /dev/null +++ b/.agents/notes/implemented/bug-fix/2026-07-28-load-pre-identity-session-messages.i18n.yaml @@ -0,0 +1,6 @@ +# Bilingual-pair consistency record (docs/i18n/README.md): the git blob hash of each +# side as of the last confirmed-consistent state.

A defined token with no consumer is not a theme: every scrolling region rendered the user agent's own scrollbar, which knows nothing about the palette, so the dark theme showed a light native bar against dark surfaces. + +The visible symptom that surfaced the gap was elsewhere. The workspace browser's session list (`.list` in `WorkspaceBrowser.module.css`) is the sidebar's only scrolling region, and each row's trailing content sits flush against the row's 8px right padding — `.time` in `rows/Rows.module.css` is `flex: none`, as are the action buttons that replace it on hover. An overlaid scrollbar therefore painted on top of the relative timestamp. Reserving space in that one list would have left the bar itself unthemed, so the two halves are one change. + +## Decision + +`packages/client/ui-theme/src/styles/scrollbar.css` is the sole consumer of the four tokens, and the fifth ui-theme sheet in the shell's import chain (`packages/client/web/src/base.css`). It follows `design-platform.css` there because it reads that sheet's tokens. + +The rules sit on `body`, not `html`. `design-platform.css` declares the `--dsw-alias-*` tokens on `body`, with the dark overrides on `body[data-ds-dark-theme]`, and custom properties inherit only downward; an `html` rule resolves them to the guaranteed-invalid value, at which point `scrollbar-color` computes to `auto` and no theming happens at all. + +`scrollbar-width` and `scrollbar-color` are declared on `body, body *` rather than once at the top. Inheritance would pass down the color already substituted at `body`, so a descendant rebinding the indirection could not change its own scrollbar; re-declaring makes each element substitute the variable as it sees it. `scrollbar-width` is not an inherited property in the first place, so it needs the per-element declaration regardless. The `::-webkit-scrollbar*` pseudo-elements are likewise not inherited and are matched unscoped. + +The two renderings are mutually exclusive, and the exclusion is enforced rather than assumed. A non-`auto` `scrollbar-width` or `scrollbar-color` makes Chromium and Safari discard every `::-webkit-scrollbar*` rule for that element, `::-webkit-scrollbar-thumb:hover` included. Declaring both unconditionally therefore leaves the hover token rendering nowhere at all: the engines that implement the hover pseudo-element are exactly the ones the standard properties silence, and Firefox has no hover pseudo-element to fall back on. The standard properties consequently sit inside `@supports not selector(::-webkit-scrollbar)`, which is true only where the pseudo-element is unimplemented, so Firefox takes the standard path and WebKit-based engines take the pseudo-element path. The WebKit rules are not gated in turn: an engine without those pseudo-elements drops them as unknown selectors, so a gate would only restate what selector matching already does. An engine too old for the `selector()` function makes the condition invalid, which evaluates false and selects the pseudo-element path — the correct side for the pre-16.4 Safari that is the realistic case for that reading. + +Both paths read one indirection pair, `--dsh-scrollbar-thumb` and `--dsh-scrollbar-thumb-hover`, bound on `body` to the l1 (base-surface) tokens. **This is the rebinding contract, and it is the part the CSS alone does not state**: an elevated surface sets `--dsh-scrollbar-thumb: var(--dsw-alias-scrollbar-bg-l2)` and `--dsh-scrollbar-thumb-hover: var(--dsw-alias-scrollbar-hover-l2)` on its own container, and that one rebind reaches the standard properties and the WebKit pseudo-elements together. The pair is rebound as a pair; rebinding the resting thumb alone leaves the hover state on the base-surface token. The mechanically discoverable subset is owned by `packages/client/ui-theme/tests/scrollbar-styles.spec.ts`: any sheet that both scrolls and paints an elevated surface must rebind, so this note no longer maintains a complete surface inventory. Most declare the pair on the elevated card rather than on the scrolling descendant, because elevation belongs to the surface and custom properties inherit to whichever child actually scrolls. + +Four surfaces — `Menu`, `InputBar`, `QuestionComposer`, and `TodoPanel` — were missed in the first implementation and found in review, which is why the per-sheet rebinding contract is checked mechanically rather than by inspection. + +The elevated set is resolved from the palette's own dark elevation ladder — the surface tokens whose dark value lands on `bg-layer-2` or `bg-layer-3`, which is the step the l1/l2 split encodes. Deriving it instead from the sheets that already rebind was the first attempt and is unsound: such a set can only confirm what someone already remembered, and a surface nobody has rebound yet — exactly the case the check exists for — defines itself as unelevated. `--dsw-specific-tip` proved it, resolving to the menu surface's rung while the todo panel scrolled on it unrebound and the derived check stayed green. + +Scope is by token family, not by geometry: only `--dsw-alias-bg-*` and `--dsw-specific-*` name a surface. `--dsw-alias-button-*`, `--dsw-alias-interactive-*`, and `--dsw-alias-markdown-*` reach the same rungs while naming a control or an inline span that no scroll container renders its bar against. Shape cannot make that call, since a floating button legitimately carries a radius, a shadow, and a fixed size. The check is per sheet rather than per rule because the card and the descendant that scrolls are separate rules. That approximation cannot detect a scrolling component embedded in an elevated card painted by another package's stylesheet, as `DirectoryBrowser` inside `Modal` demonstrated; cross-sheet composition remains a review and assembled-UI responsibility. + +The track and the corner stay transparent, so the thumb reads against whatever surface scrolls under it; only the thumb and its hover state carry a token color. + +`.list` declares `scrollbar-gutter: stable`, which keeps the bar beside the rows instead of on top of them. `stable` rather than `auto` because `auto` reserves the gutter only while the list actually overflows: expanding a workspace group would then shift every row horizontally at the moment it starts scrolling. The reservation is unconditional and the rows never move. + +The gutter and the sheet's `::-webkit-scrollbar` width are jointly necessary against an overlay scrollbar, which is the configuration where the symptom exists at all. Measured on the running app by deleting each from the live cascade with the other left in force: either deletion alone takes the list's band from 8 to 0. The gutter states that space be reserved, and the pseudo-element width is what makes chromium treat the bar as occupying layout space rather than floating over the content. Neither half of this change is therefore optional for the reported bug, which is a second reason the two halves ship together. + +## Alternatives considered + +**Per-module `::-webkit-scrollbar` rules in each scrolling component sheet.** Rejected: the client has thirteen scrolling containers across nine packages, every one would carry the same block, and the fourteenth would ship unthemed with nothing failing. A skin driven by design tokens belongs in the package that owns the tokens. + +**An opt-in utility class that each scroll container adds.** Same duplication removed, but the failure mode stays: a new scroll container is themed only if its author remembers the class, and the omission is invisible in review. The `body, body *` form has no opt-in step to forget; a container that genuinely wants a different bar overrides the indirection, which is the same mechanism elevated surfaces use. + +**Bind the properties on `html`.** The natural place for a document-wide skin, and it fails measurably: with the rule on `html` a scroll container computes `scrollbar-color: auto` in chromium, because the alias tokens are not in scope there. + +**Declare the properties once and let them inherit.** Fewer matched elements, and it breaks the rebinding contract — inheritance carries the substituted color, not the variable reference, so an elevated surface could not retint its own scrollbar. It is also incomplete on its own terms, since `scrollbar-width` does not inherit. + +**Declare the standard properties and the pseudo-elements unconditionally, without the `@supports` gate.** This is what the change originally shipped, and review caught it. Measured in chromium on probe elements with `scrollbar-gutter: stable` so the band is observable: an 8px `::-webkit-scrollbar` alone reserved a 30px band (the sheet's width plus the UA's buttons), and adding `scrollbar-width: thin` to the same element dropped it to the 10px `thin` reserves — the pseudo-element rules were being discarded, not merged. Every `::-webkit-scrollbar-thumb:hover` rule went with them, so both hover tokens and all four elevated surfaces' hover rebinds were dead code on the engine most users run. + +**Gate the WebKit rules too, behind `@supports selector(::-webkit-scrollbar)`.** Symmetrical to read, and wrong in one direction: it would hide the rules from an engine that implements the pseudo-elements but not `selector()`, which is the pre-16.4 Safari the ungated form serves correctly. Unknown selectors are already dropped, so the gate adds no protection to pay for that. + +**Pad the rows instead of reserving the gutter (extra right padding on `.list`, or moving `.time` inward).** Rejected: padding applies whether or not a bar is present, so it costs horizontal room in the common short-list case, and it fixes exactly one container while leaving every other scrolling region's content under its bar. + +**`scrollbar-gutter: auto` on `.list`.** The reservation appears when the list overflows, which is when the bar exists. Rejected because the sidebar's lists grow and shrink as groups expand, so the reservation would appear and disappear under the user's cursor and shift the rows with it. + +## Consequences + +- Every scroll container in the client draws the themed thumb: `rgb(229, 229, 229)` on a light base surface, `rgb(60, 60, 61)` on a dark one, and `rgb(84, 85, 87)` for a dark elevated surface that rebinds to the l2 pair. +- The two renderings are separately specified, so a change to the thumb's geometry or hover behavior has to be made twice — once in `scrollbar-width`/`scrollbar-color`, once in the pseudo-elements. Routing both through the indirection pair confines that duplication to the properties Firefox and WebKit do not share. +- The hover tokens (`--dsw-alias-scrollbar-hover-l1`/`-l2`) render only on the pseudo-element path. Firefox states one thumb color through `scrollbar-color` and derives its own hover treatment, so a design change to the hover colors is visible in Chromium and Safari and not in Firefox. This is a limit of `scrollbar-color`, not of the sheet. +- `body *` matches every element, for two properties whose effect the user agent already limits to elements that actually scroll. The cost is a broad selector; the alternative was a rebinding contract that does not work. +- The workspace list is permanently narrower by the reserved band, at every list length. That is the trade the fix buys: stable row geometry instead of a timestamp that is legible only while the list is short. +- There is no track token in the palette, so a design that later wants an opaque track needs a new alias token rather than a literal color in this sheet. + +## Testing + +Three unit specs read the CSS text on disk. `ui-theme/tests/scrollbar-styles.spec.ts` scans the scrollbar token set out of `design-platform.css` rather than hardcoding it, so adding, renaming, or dropping a token moves the assertions with it, and checks that every token has a consumer and that each elevated surface rebinds a complete pair. It also pins the path split by source offset: the standard properties inside the gate block, the `::-webkit-scrollbar*` rules and every read of the hover indirection outside it. That split needs an offset assertion because the spec's rule parser flattens through at-rules, so a gate deleted or a declaration moved across it leaves every other assertion in the file green. + +`apps/web/tests/sidebar-scrollbar.e2e.ts` covers the facts only a real engine reports: the reserved band width, and which rendering path the engine took. It needs no model calls — the list only has to overflow — so it seeds cold sessions from an existing committed fixture read-only. + +That scenario also commits a golden, `snapshots/sidebar-scrollbar/geometry.expected.md`, holding the resolved scrollbar style and geometry in both palettes. The aria goldens the other web scenarios commit cannot carry a CSS-only change: it alters no DOM and no accessible name, so their normalized trees are byte-identical with and without it. Recording the resolved values instead makes an unintended shift in thumb colour, band width, or rendering path a reviewable diff rather than a threshold someone has to reason about. Absolute coordinates are deliberately excluded — `timeRight` and the two edges depend on the sidebar's laid-out width and on font metrics, so committing them would produce a fixture that has to be re-recorded per platform and would document the platform rather than the change. What is recorded is the band, the overlap, and two orderings, each a difference or a comparison that survives any layout preserving the reservation. + +Confirmed in headless chromium on the built client by reading computed values, which is what distinguishes a working token chain from a syntactically valid one: a scroll container computes the l1 thumb color in each palette, and a container that rebinds the indirection computes the l2 color, proving the rebind reaches the computed value rather than only the custom property. Firefox was verified the same way for the standard path, including the l1-to-l2 rebind on `scrollbar-color`; headless Firefox reports `scrollbar-width: none` on every element, styled or not, which is a headless artifact rather than an effect of the sheet. + +Two chromium measurement limits shape what the e2e can assert. The gate makes chromium report `scrollbar-width` and `scrollbar-color` as `auto`, so the substituted `scrollbar-color` is no longer the observable — the e2e asserts the `auto` reading deliberately, since a concrete value there would mean the gate leaked and silenced the pseudo-elements. And `getComputedStyle(el, '::-webkit-scrollbar-thumb')` folds in the `::-webkit-scrollbar-thumb:hover` rule, so it reports the hover color at rest and pins neither state; proven by deleting the hover rule through `CSSStyleSheet.deleteRule` in the live page, which flipped that same query from the hover color to the resting one. The e2e therefore reads the resting and hover colors as the indirection variables resolve on the list — one throwaway probe element per variable, because `getComputedStyle` returns a live declaration and a reused probe reports only the last value read — and reads the hover declaration out of the cascade as rule text. + +The gate itself has a negative control at the level it operates on: removing the `@supports` wrapper from the sheet, rebuilding `build:web`, and rerunning the e2e turns the `scrollbar-width: auto` assertion red with `thin`, which is the suppression the gate exists to prevent. + +Headless chromium draws overlay scrollbars, and that is the configuration in which the reported symptom exists, so the e2e reproduces the bug rather than approximating it: against clean master the list's band is 0 and the bar covers 7px of the relative time. A reserved gutter there does not shrink `clientWidth`, so an assertion comparing the time element's right edge against the client-area edge holds with and without the reservation and would pass or fail on the platform's scrollbar style rather than on the declaration under test. The two signals that do separate the states are the `offsetWidth - clientWidth` band and `timeCoveredBy`, the overlap measured against the bar's own width. + +Both are asserted because each catches a different regression, established by mutating one declaration at a time with the other assertions in that test silenced. Removing only the gutter leaves `timeCoveredBy` at 0 — the bar is then 8px and the row's right padding is also 8px, so it abuts the timestamp without covering it — and the band assertion is what fails. Removing the pseudo-element width as well, which is the actual master state, produces the overlap, and `timeCoveredBy` fails at 7. A headed run under xvfb cannot show the symptom in either state, because chromium paints a classic space-consuming bar there and `clientWidth` already excludes it. + +Verifying browser-visible plugin CSS needs a rebuild `pnpm run build:web` does not perform. `WorkspaceBrowser.module.css` never reaches `apps/web/dist`: ui-workspace loads as a runtime plugin and its CSS is inlined into `packages/client/ui-workspace/lib/client.js`, built by that package's own `bundle` script. A negative control that reruns only `build:web` therefore exercises a stale bundle and passes with the declaration removed, which reads as a vacuous test rather than as an invalid control. Rebuild with `pnpm --filter @deepseek-ai/dsh-client-ui-workspace run bundle`, confirm the artifact by grepping `lib/client.js` for the declaration, then `build:web`. + +`test:web` ran `build:web` alone, so every scroll-region or plugin-CSS change hit that trap; it now runs `build` first, which covers `packages/*/*` and so rebuilds the plugin bundles. `check-all` already ordered `build` before `build:web`, so CI was never exposed — only the local script was, which is exactly where a stale-bundle pass is most likely to be believed. diff --git

+暴露这一缺口的可见症状出在别处。工作区浏览器的会话列表（`WorkspaceBrowser.module.css` 中的 `.list`）是侧边栏里唯一的滚动区域，而每一行的尾部内容都紧贴该行 8px 的右内边距——`rows/Rows.module.css` 中的 `.time` 取 `flex: none`，hover 时取代它的操作按钮也是如此。于是覆盖式滚动条会画在相对时间戳之上。只在这一个列表里预留空间，滚动条本身仍然没有主题，因此两部分合为一次变更。 + +## 决策 + +`packages/client/ui-theme/src/styles/scrollbar.css` 是这四个 token 的唯一消费方，也是壳的导入链（`packages/client/web/src/base.css`）中第五张

处代入完成的颜色值，因此后代元素重新绑定这层间接变量也无法改变自己的滚动条；逐元素重新声明使每个元素按它自己看到的取值代入变量。`scrollbar-width` 本身就不是可继承属性，无论如何都需要逐元素声明。`::-webkit-scrollbar*` 伪元素同样不继承，因此以不加限定的选择器匹配。 + +两种渲染互斥，而这种互斥是被强制的，不是假定的。`scrollbar-width` 或 `scrollbar-color` 只要取非 `auto` 值，Chromium 与 Safari 就会丢弃该元素上的全部 `::-webkit-scrollbar*` 规则，`::-webkit-scrollbar-thumb:hover` 也在其中。因此无条件地同时声明会让 hover token 在任何地方都得不到渲染：实现了 hover 伪元素的引擎，恰恰就是被标准属性静音的那些，而 Firefox 没有 hover 伪元素可作退路。于是标准属性写在 `@supports not selector(::-webkit-scrollbar)` 之内，该条件只在伪元素未被实现处为真，因此 Firefox 走标准属性路径，WebKit 系引擎走伪元素路径。WebKit 规则不再反向加门禁：不实现这些伪元素的引擎会把它们当作未知选择器丢弃，因此加门禁只是重述选择器匹配本身已经做的事。对于旧到不支持 `selector()` 函数的引擎，该条件无效，从而求值为假并选中伪元素路径——对于这条判断下现实存在的 16.4 之前的 Safari，这正是正确的一侧。 + +两条路径都读取同一组间接变量 `--dsh-scrollbar-thumb` 与 `--dsh-scrollbar-thumb-hover`，它们在 `body` 上绑定到 l1（基础表面）token。**这就是重新绑定契约，也是单看 CSS 无法得知的部分**：抬升表面在自己的容器上设置 `--dsh-scrollbar-thumb: var(--dsw-alias-scrollbar-bg-l2)` 与 `--dsh-scrollbar-thumb-hover:

所有：任何既滚动又绘制抬升表面的样式表都必须重新绑定，因此本 note 不再维护完整的表面清单。多数把这组变量声明在抬升卡片上而非滚动的后代元素上，因为抬升层级属于这个表面，而自定义属性会继承到真正滚动的那个子元素。 + +`Menu`、`InputBar`、`QuestionComposer` 与 `TodoPanel`

之分所编码的层级差。最初的做法是从已经做了重新绑定的样式表反向推导，那是不成立的：这样得到的集合只能确认别人已经记得的部分，而尚无人重新绑定的表面——恰恰就是这项检查存在的理由——会把自己定义成「非抬升」。`--dsw-specific-tip` 证明了这一点：它解析到与菜单表面相同的那一档，待办面板在它上面滚动却没有重新绑定，而推导式的检查依然是绿的。 + +判定范围依据 token

只在列表确实溢出时才预留空位：那样展开一个工作区分组时，所有行会在列表开始滚动的那一刻发生水平位移。`stable` 的预留是无条件的，行不会移动。 + +面对覆盖式滚动条——也就是这个症状唯一存在的那种形态——空位声明与样式表里的 `::-webkit-scrollbar` 宽度是共同必要的。在运行中的应用上实测：保留其中一条、从活的层叠中删掉另一条，任意一次单独删除都会让列表的条带从 8 降到 0。空位声明表述的是「要预留空间」，而伪元素宽度才是让 chromium 把滚动条视为占据布局空间、而不是浮在内容之上的原因。因此对这个 bug 而言，本次变更的两半都不是可选项，这也是两半必须一起交付的第二个理由。 + +## 曾考虑的替代方案 + +**在每个滚动组件的样式表里各写一份 `::-webkit-scrollbar` 规则。** 之所以否决：客户端共有分布在九个包中的十三个滚动容器，每一个都要带上同一段规则，而第十四个会在没有任何门禁报错的情况下漏掉主题。由设计 token 驱动的皮肤应当归属于拥有这些 token 的包。 + +**提供一个工具类，由各滚动容器自行加上。** 重复同样被消除，但失败方式依旧存在：新的滚动容器只有在作者记得加类名时才有主题，而遗漏在评审中看不出来。`body, body *` 这种写法没有需要记住的启用步骤；确实想要不同滚动条的容器可以覆盖间接变量，这与抬升表面使用的机制相同。 + +**把这两个属性绑定在 `html` 上。** 这是文档级皮肤最自然的落点，而它的失败是可测量的：规则挂在 `html` 上时，chromium 中滚动容器计算出的 `scrollbar-color` 为 `auto`，因为别名 token 在那个作用域内不存在。 + +**只声明一次，靠继承下传。** 匹配的元素更少，但它破坏重新绑定契约——继承携带的是代入后的颜色，而不是变量引用，因此抬升表面无法给自己的滚动条换色。它本身也不完整，因为 `scrollbar-width` 不继承。 + +**不加 `@supports` 门禁，无条件同时声明标准属性与伪元素。** 这正是本次变更最初提交的形态，被评审发现。在 chromium 中于带 `scrollbar-gutter: stable`（使条带可观测）的探针元素上实测：单独一条 8px 的 `::-webkit-scrollbar` 预留出 30px 条带（样式表指定的宽度加上浏览器自带的按钮），而给同一元素加上 `scrollbar-width: thin` 后降到 `thin` 所预留的 10px——说明伪元素规则是被丢弃，而不是被合并。全部 `::-webkit-scrollbar-thumb:hover` 规则随之失效，因此两个 hover token 与四处抬升表面的 hover 重新绑定，在多数用户实际使用的引擎上都是死代码。 + +**给 WebKit 规则也加门禁，写成 `@supports selector(::-webkit-scrollbar)`。** 读起来对称，但在一个方向上是错的：它会对「实现了伪元素但不支持 `selector()`」的引擎隐藏这些规则，而那正是不加门禁时能被正确服务的 16.4 之前的 Safari。未知选择器本就会被丢弃，因此这道门禁不提供任何能抵偿该代价的保护。 + +**改用内边距而不是预留空位（给 `.list` 加右内边距，或把 `.time` 向内移）。** 之所以否决：内边距无论滚动条是否存在都生效，因此在常见的短列表情形下白白占用横向空间；而且它只修好一个容器，其余每个滚动区域的内容仍然压在滚动条之下。 + +**给 `.list` 用 `scrollbar-gutter: auto`。** 空位在列表溢出时出现，也就是滚动条存在的时候。之所以否决：侧边栏的列表会随分组展开与收起而伸缩，因此空位会在用户光标之下出现又消失，并带动行一起位移。 + +## 后果 + +- 客户端的每个滚动容器都绘制带主题的滑块：亮色基础表面为 `rgb(229, 229, 229)`，暗色基础表面为 `rgb(60, 60, 61)`，重新绑定到 l2 的暗色抬升表面为 `rgb(84, 85, 87)`。 +- 两种渲染分别指定，因此改动滑块的几何或 hover 行为需要改两处：一处在 `scrollbar-width`／`scrollbar-color`，一处在伪元素。让两者都经由这组间接变量，把这份重复限制在 Firefox 与 WebKit 不共用的那些属性上。 +- hover token（`--dsw-alias-scrollbar-hover-l1`／`-l2`）只在伪元素路径上渲染。Firefox 通过 `scrollbar-color` 只表述一个滑块颜色，其 hover 表现由引擎自行推导，因此对 hover 颜色的设计改动在 Chromium 与 Safari 上可见，在 Firefox 上不可见。这是 `scrollbar-color` 本身的限制，不是这张样式表的限制。 +- `body *` 匹配所有元素，涉及的两个属性其效果本就被浏览器限制在实际会滚动的元素上。代价是一个覆盖面很宽的选择器；另一种选择是一个不生效的重新绑定契约。 +- 工作区列表在任何列表长度下都永久少了预留空位那一条宽度。这正是该修复换来的代价：以稳定的行几何，换掉只在列表较短时才可读的时间戳。 +- 调色板中没有轨道 token，因此日后若设计需要不透明轨道，要新增一个别名 token，而不是在这张样式表里写字面颜色。 + +## 测试 + +三份单元测试读取磁盘上的 CSS 文本。`ui-theme/tests/scrollbar-styles.spec.ts` 从 `design-platform.css` 中扫描出滚动条 token 集合，而不是把它写死，因此新增、重命名或删除 token 时断言会随之变化；它检查每个 token 都有消费方，且每处抬升表面重新绑定的都是完整的一对。它还以源码偏移量锁定两条路径的划分：标准属性在门禁块之内，`::-webkit-scrollbar*` 规则与每一处对 hover 间接变量的读取都在门禁块之外。这个划分必须用偏移量断言，因为该测试文件的规则解析器会把 at-rule 拉平，所以删掉门禁或把某条声明移到门禁另一侧，文件里其余全部断言仍然是绿的。 + +`apps/web/tests/sidebar-scrollbar.e2e.ts` 覆盖只有真实渲染引擎才能报告的事实：预留条带的宽度，以及引擎实际走的是哪条渲染路径。它不需要任何模型调用——列表只要溢出即可——因此以只读方式复用一份既有的已提交 fixture（测试前置数据）来铺入冷会话。 + +这个场景还提交了一份 golden（期望产物）`snapshots/sidebar-scrollbar/geometry.expected.md`，记录两套调色板下解析后的滚动条样式与几何。其余 web 场景提交的 aria golden 承载不了纯 CSS 的改动：它不改变任何 DOM、也不改变任何无障碍名称，因此有无这次改动，它们规范化后的树都是逐字节相同的。改为记录解析后的取值，就让滑块颜色、条带宽度或渲染路径的意外变化成为可评审的 diff，而不是一条需要人去推敲的阈值断言。绝对坐标被特意排除——`timeRight` 与两条边缘取决于侧边栏排版后的宽度和字体度量，把它们提交进去会得到一份需要按平台重新录制的 fixture，那记录的是平台而不是这次改动。真正记录下来的是条带、重叠量与两个先后关系，每一项都是差值或比较，因此只要预留仍然成立，任何排版下都不变。 + +在构建产物客户端上于 headless chromium 中读取计算值确认，这正是区分「token 链真正生效」与「语法合法」的手段：滚动容器在两套调色板下分别计算出 l1 的滑块颜色，而重新绑定间接变量的容器计算出 l2 的颜色，证明重新绑定作用到了计算值，而不只是作用到自定义属性上。Firefox 的标准属性路径以同样方式做了验证，包含 `scrollbar-color` 上从 l1 到 l2 的重新绑定；headless Firefox 对任何元素（无论是否被样式命中）都报告 `scrollbar-width: none`，这是 headless 的产物，不是这张样式表造成的。 + +chromium 上有两处测量限制决定了 e2e 能断言什么。门禁使 chromium 报告的 `scrollbar-width` 与 `scrollbar-color` 都是 `auto`，因此代入后的 `scrollbar-color` 不再是可观测量——e2e 特意断言这个 `auto` 读数，因为此处出现具体值就意味着门禁泄漏、伪元素被静音。另外，`getComputedStyle(el, '::-webkit-scrollbar-thumb')` 会把 `::-webkit-scrollbar-thumb:hover` 规则一并折算进去，因此它在静止态就报告 hover 颜色，两种状态都锁不住；这一点由在运行中的页面里用 `CSSStyleSheet.deleteRule` 删掉 hover 规则得证——同一查询随之从 hover 颜色翻转为静止态颜色。因此 e2e 改为读取那组间接变量在列表上代入后的静止态与 hover 颜色（每个变量用一个一次性探针元素，因为 `getComputedStyle` 返回的是活的声明对象，复用探针只会报告最后一次读到的值），并把 hover 声明当作规则文本从层叠中读出。 + +门禁本身在它起作用的层面有反向对照：把样式表中的 `@supports` 包裹去掉、重新 `build:web`、再跑 e2e，`scrollbar-width: auto` 那条断言会以 `thin` 变红，而这正是门禁存在所要阻止的那种静音。 + +headless chromium 绘制的是覆盖式滚动条，而这恰好就是被报告症状存在的那种形态，因此这个 e2e 复现的是这个 bug 本身，而不是它的近似：在干净的 master 上，列表条带为 0，滚动条盖住相对时间 7px。其中预留空位不会缩小 `clientWidth`，因此把时间元素右边缘与内容区右边缘做比较的断言在有无预留的两种状态下都成立，它的通过或失败取决于平台的滚动条样式，而不是取决于被测的那条声明。真正能区分两种状态的两个量是 `offsetWidth - clientWidth` 条带，以及以滚动条自身宽度为基准量出的重叠量 `timeCoveredBy`。 + +两者都要断言，因为各自捕捉的是不同的回归；这一点通过每次只改动一条声明、并把同一个测试里的其余断言静音来确定。只删掉空位声明时 `timeCoveredBy` 仍为 0——此时滚动条是 8px，而行的右内边距也是 8px，于是它紧贴时间戳但并未盖住——失败的是条带那条断言。再把伪元素宽度也删掉（这才是 master 的真实状态）才会产生重叠，此时 `timeCoveredBy` 以 7 变红。在 xvfb 下的有头运行无论哪种状态都看不到这个症状，因为 chromium 在那里画的是经典占位滚动条，`clientWidth` 本来就已经把它排除了。 + +验证浏览器可见的插件 CSS 需要一次 `pnpm run build:web` 并不执行的重建。`WorkspaceBrowser.module.css` 从不进入 `apps/web/dist`：ui-workspace 以运行时插件方式加载，其 CSS 内联进 `packages/client/ui-workspace/lib/client.js`，由该包自己的 `bundle` 脚本构建。因此只重跑 `build:web` 的反向对照实际测的是旧产物，去掉声明后仍会通过，看起来像测试无效，实际是对照无效。正确做法是先 `pnpm --filter @deepseek-ai/dsh-client-ui-workspace run bundle`，用 grep 在 `lib/client.js` 中确认该声明确实存在或消失，然后再 `build:web`。 + +`test:web` 原先只运行 `build:web`，因此任何滚动区域或插件 CSS 的改动都会碰到这个陷阱；现在它先运行 `build`，而 `build` 覆盖 `packages/*/*`，从而会重建各插件产物。`check-all` 本来就把 `build` 排在 `build:web` 之前，所以 CI 从未受影响——受影响的只有本地脚本，而这恰恰是「产物过期却通过」最容易被当真的地方。 diff --git

Each bridge ignores unsupported events before group parsing, discards matcher fields on supported events without matcher subjects, validates the remaining runnable groups, and treats an invalid regex there as a whole-config load failure, with a stable dialect/pattern/event diagnostic; no hook listeners are registered. Runtime matching still contains an invalid regex as a non-match, so a direct library caller never throws into the loop. - **Execution** — `runHook(bash, hook, options)`. Runs a command hook through the `ctx.bash` seam rather than a bespoke `spawn`: the executor already provides the scrubbed-but-overridable env, process-group kills, and timeout the protocol needs, and `dsh-bash`'s `stdin`/`env` fields (added for exactly this) are the trusted-plugin surface an in-process bridge is allowed to use. It serializes the bridge-built payload to stdin (trailing newline iff CC), honors the hook's `timeoutSec` (else `DEFAULT_HOOK_TIMEOUT_MS`, the 10-minute reference default both dialects share), and never throws (an executor rejection becomes a non-blocking-error `HookOutput`). - **Decode** — `parseHookOutput(exit, stdout, stderr)`, the exit-code + structured-stdout codec, producing a dialect-neutral `HookOutput`.

The latest logged request header restores a used target; a selection that never reaches a request remains process-local. ### Terminal ownership diff --git a/.agents/notes/implemented/feature/2026-07-17-dedicated-full-screen-tui-front-door.zh.md b/.agents/notes/implemented/feature/2026-07-17-dedicated-full-screen-tui-front-door.zh.md index 6a0c2f1281..4624a4db3d 100644 --- a/.agents/notes/implemented/feature/2026-07-17-dedicated-full-screen-tui-front-door.zh.md +++ b/.agents/notes/implemented/feature/2026-07-17-dedicated-full-screen-tui-front-door.zh.md @@ -14,7 +14,7 @@ Status: implemented DeepSeek Harness 将 [`@deepseek-ai/dsh-tui`](../../../../packages/ui/tui/README.md) 作为独立的 Cordis 插件交付。该插件只负责终端输入与呈现；agent 生命周期、会话持久化、工具执行以及模型可见的提问工具仍由不同组合项负责。插件要求 stdin 和 stdout 均为 TTY；条件不满足时会失败，不会静默切换为逐行输出。 -应用组合层只有一个终端入口。`@deepseek-ai/dsh-tui-demo` 在已配置 agent 之前挂载 TUI，`examples/tui-agent` 直接拥有交互式 coding 组装及其 Code Mode overlay。非交互任务使用 `@deepseek-ai/dsh-cli-demo`；ACP 仍是独立的自动化协议。 +只有一个终端入口。`@deepseek-ai/dsh-tui` 在已配置 agent 之前挂载，而 `apps/cli/config/tui.cordis.yml`——叠加在共享 `base.cordis.yml` 之上的 overlay——拥有交互式 coding 组装。非交互任务使用官方 headless 界面；ACP 仍是独立的自动化协议，并拥有受支持的 Code Mode demo。 所选入口接收预创建 agent 使用的同一个新建或恢复 `SessionId`。入口先于 agent 组合挂载，等待相符的根 agent 出现，然后才进入全屏模式。因此，相符的 `agent-loop/config-start-failed` 事件会在接管屏幕前报告，并以状态码 1 退出。 @@ -24,7 +24,7 @@ TUI 从活跃的 `session.surface` 重建 transcript（文本记录），并在 agent 空闲时，编辑器输入调用 `agent.send()`；轮次运行中则调用 `agent.steer()`。取消、推理显隐、工具卡片展开、重绘、清空 transcript 和退出都只是终端控制。`/exit` 和 `/quit` 共用同一条退出路径：先取消进行中的轮次，等待 agent 空闲，然后恢复并关闭终端。空闲态页脚根据 `tokenMeter` 得出上下文占用率，并显示所选模型和显式选定的推理强度；agent 运行期间，该摘要会替换为带已用时长的活动指示和 Escape 中断提示。`/status` 在这两种状态下均可用，并会追加一份仅在终端显示的详细快照，其中包括会话标识与时间戳、所选模型、推理强度（或默认状态）及推理显隐状态、从事件日志归并得出的生命周期计数、与页脚一致的去重用量分项和 KV 缓存命中率，以及 `tokenMeter` 给出的上下文用量和所选模型公布的容量。插件注册共享的 `userInteraction` 提供方，在左下角宽幅键盘操作面板中呈现排队的问题，面板显示批次进度、带编号的选项和对齐的描述；面板的操作提示只列出在当前选项数量下有意义的操作，仅有一个选项时不显示导航项；agent 行为和答案日志仍由既有服务负责。 -`/model` 命令将建议性的 `ctx.llm` 目录呈现为键盘选择器，并且只更改当前 TUI 会话的目标；带参数的形式仍可直接选择目标。每个模型行都持有适配器公布的推理强度顺序和默认值：按 Shift+Tab 可循环切换该行的推理强度；如果适配器没有公布默认值，循环中还会包含提供方默认行为；没有可选元数据的模型则保持不变。agent 作用域内的 prompt 组装和请求两条 waterfall（瀑布式事件）会为每个步骤快照一次同一个提供方/模型/推理强度目标，因此即使命令在组装期间到达，`{{provider}}` / `{{model}}` 插值与请求路由也不会分裂。系统通过日志中最新的请求头恢复已经使用过的目标；未被请求使用的选择只保留在当前进程中。 +`/model` 命令将建议性的 `ctx.llm` 目录呈现为键盘选择器，并且只更改当前 TUI 会话的目标；带参数的形式仍可直接选择目标。选择器在列表上方设有一个过滤框：输入内容会按对每行 `provider/model` 标签、模型名称和描述的大小写不敏感子串匹配来缩小行集，并在原先高亮行仍通过过滤时保持其选中状态；Escape 会先清空非空的过滤内容，再次按 Escape 才取消选择器。每个模型行都持有适配器公布的推理强度顺序和默认值：按 Shift+Tab 可循环切换该行的推理强度；如果适配器没有公布默认值，循环中还会包含提供方默认行为；没有可选元数据的模型则保持不变。agent 作用域内的 prompt 组装和请求两条 waterfall（瀑布式事件）会为每个步骤快照一次同一个提供方/模型/推理强度目标，因此即使命令在组装期间到达，`{{provider}}` / `{{model}}` 插值与请求路由也不会分裂。系统通过日志中最新的请求头恢复已经使用过的目标；未被请求使用的选择只保留在当前进程中。 ### 终端所有权 diff --git a/.agents/notes/implemented/feature/2026-07-20-dsh-cli-personal-config.i18n.yaml b/.agents/notes/implemented/feature/2026-07-20-dsh-cli-personal-config.i18n.yaml index 76dd488060..11674d7747 100644 --- a/.agents/notes/implemented/feature/2026-07-20-dsh-cli-personal-config.i18n.yaml +++ b/.agents/notes/implemented/feature/2026-07-20-dsh-cli-personal-config.i18n.yaml @@ -1,6 +1,6 @@ # Bilingual-pair consistency record (docs/i18n/README.md): the git blob hash of each # side as of the last confirmed-consistent state.

On submit it loads the named skill and delivers one text block as a user turn — sent with `agent.send()` while idle and `agent.steer()` while running, the same rule as ordinary editor input. The block is `renderSkillInvocation(skill, instructions)`: a `` element wrapping the skill body, preceded by one resource-base line when the provider exposes one, with the user's trailing text appended after a blank line. The command is a TUI-only affordance; it adds no model-facing tool. Its visibility and loading policy comes from the shared [independent model and user skill invocation policy](2026-07-28-skill-invocation-policy.md). The TUI reads the skill service through `ctx.get('skills')`, not a declared injection, because skills mount conditionally: a deployment without the registry keeps a working front door, and `/skill:` there reports that skills are unavailable rather than failing to mount. `createTuiChat` is synchronous while `ctx.skills.list()` is async, so autocomplete seeds the static slash commands immediately and rebuilds the provider with `skill:` entries once the catalog resolves; a resolution that arrives after disposal is dropped, and a rejected lookup keeps the base commands. -Autocomplete lists only model-invocable skills — it is built from `list()`, which omits `disableModelInvocation` skills — while manual submission resolves through `get()`, which the skill registry documents as the trusted-caller path that returns disabled skills too. So a person can load any skill by typing its exact name, but the completion menu never advertises a skill the model is meant not to see. Each completion entry is labeled with its winning source's scope — `(project)` for the `project-` sources, `(user)` for every other source — in the slash-command argument-hint slot, which the menu shows but selection never inserts, so trailing instructions still follow the completed name. An unknown name, an empty name after the prefix, and a lookup failure each surface as a transcript notice without sending anything. +Autocomplete filters the invocation-neutral `list()` result with `isUserInvocable`, and manual submission applies the same predicate after trusted `get()` resolves the definition. A user-only skill can therefore appear and load even when model invocation is disabled, while a user-disabled skill is neither advertised nor loadable by exact name. Each completion entry is labeled with its winning source's scope — `(project)` for the `project-` sources, `(user)` for every other source — in the slash-command argument-hint slot, which the menu shows but selection never inserts, so trailing instructions still follow the completed name. An unknown name, an empty name after the prefix, a user-disabled name, and a lookup failure each surface as a transcript notice without sending anything. `renderSkillInvocation` and the resource-base line are the TUI's own, deliberately not reused from `dsh-tool-skill`'s `skill` tool result. The tool wraps a body in ``/``/`` for a *tool result*; a manual invocation is a *user turn*, and coupling the two renderers would force one model-facing shape to serve both surfaces. The cost is two renderers that both format a skill body; the benefit is that each surface's model-facing text evolves independently, and each is pinned where it is produced. ## Alternatives considered -**Add a `user-invocable` frontmatter field and enforce it in the registry.** Rejected for this change.

This change introduces the client goal verbs (runtime session methods over RPC) and the first goal UI together. Placement follows the redesign's premise that goal presence belongs to the composer's context: the goal is a property of the work the user is about to prompt, so its indicator belongs in the composer-context stack; the [composer context stack decision](../bug-fix/2026-07-30-composer-context-stack-order.md) owns its position among Goal, Todo, Queue, and the composer. The mock keeps only a sparkle, a phase word ("Ongoing/Paused/Blocked Goal"), the truncated objective, and edit/clear icon actions, with resume appearing only on a paused goal. + +## Decision + +`GoalBar` (`packages/client/ui-goal/src/client/GoalBar.tsx`) is a props-driven, self-contained component registered first in the composer's input-dock list. Its standalone 752px card follows the composer's horizontal geometry, and every visible state shares one fixed 36px height so switching phases never resizes it. Loading (`goal === undefined`), absent (`goal === null`), and `phase === 'complete'` render nothing — a completed goal is history, not chrome. + +Visibility drives the label and actions: active shows "Ongoing Goal" with pause/edit/clear; paused shows "Paused Goal" and swaps pause for a resume icon button; blocked shows "Blocked Goal" and carries `blockedReason.message` as the strip's `title` tooltip. Goal creation lives on the `/goal` command, not in the bar. The pencil swaps the strip for an inline edit form prefilled with the current objective: Enter or the check button saves through `GoalBarActions.onEdit(objective)`, Esc cancels, and an all-whitespace objective keeps save disabled. The form closes only when the edit succeeds; a failure preserves the draft and displays the error in the bar. Resume and clear failures are displayed there as well. Clear otherwise calls `onClear` directly with no confirmation — a clear keeps a durable tombstone, so nothing is unrecoverable. An effect keyed on the goal's id drops the edit form when the goal's identity changes, so a surviving draft can never be written over the goal that replaced it. + +`GoalBarActions` lives in ui-goal's slot contract (`packages/client/ui-goal/src/client/slots.ts`) and carries exactly the rendered verbs: `onEdit`/`onPause`/`onResume`/`onClear`. Each callback asynchronously returns an explicit success/failure result so `GoalBar` owns its transitions and error display. `apply.ts` wires them to the runtime session methods; the runtime session resolves the current goal's compare-and-set ref internally, so the UI passes no ref. + +The runtime session gains the goal surface the strip (and future UI) needs: `fetchGoal` populates the snapshot on open, and a live `context/message` carrying `goal/change` meta triggers a coalesced refetch — concurrent triggers share the in-flight `goal.get`, while a trigger received during that read schedules one coalesced trailing read so independently ordered notifications and GET responses cannot leave stale state. Window replays never refetch, and matching the meta kind (rather than a goal key) also catches clear tombstones written by other clients. The six mutation verbs fold transport failures into `{ ok: false }` results like every sibling session method, and a get result older than a mutation response that landed mid-flight is dropped. + +The strip's background is `--dsw-alias-interactive-bg-hover` rather than the mock's literal `#F5F6F7`: the translucent hover gray resolves to that value over the white light-theme base and lifts the strip off the composer card in dark mode, where a static light token would sink. All colors are `--dsw-*` tokens. + +## Testing + +`packages/client/ui-goal/tests/goalbar.spec.tsx` pins the behavior through props alone: loading/absent/complete render nothing, the active strip renders label/objective and fires clear, the edit form prefills, rejects empty, saves on Enter, cancels on Esc, and resets when the goal's identity changes, the active strip fires pause, the paused strip fires resume, and the blocked strip exposes the reason tooltip. Component failure-path cases prove that a failed edit preserves its draft and that edit/resume/clear errors remain visible in the bar. The skeleton specs mount `ConversationRoot` with and without `goalActions`; the undefined case is seeded with an active goal, so the missing gate — not the missing goal — is what hides the strip. Runtime session specs pin the folded-error results, the live-only in-flight-plus-trailing refetch, and the stale-read guard. A keyless real-browser smoke boots the assembled application through `boot → RPC → runtime → GoalBar` and records an inline snapshot of the rendered label, objective, and actions. + +## Alternatives considered + +- **Put the strip in the session header** — rejected because the redesign's premise is that goal presence belongs to the composer's context;

The web wire contract had already reserved the seats — `approval/requested`/`approval/resolved` mux frames, `POST /api/respond` with `ApprovalResponsePayload`, client-side `pendingBuffers` — but the host `respond` was a stub, no answerer bridged `ctx.approval` to the stream, no RPC exposed the permission select, and the PendingCard rendered approvals as visible-but-unanswerable. + +## Decision + +The web host composes the same sandboxed product path as the acp-agent composition: `dsh-sandbox-local`, `dsh-sandbox-policy`, `dsh-bash-sandbox`, `dsh-fs-sandbox`, `dsh-user-approval`, and `dsh-permission`, with `BootHostOptions.sandbox` supplying the deployment defaults (`mode`, default `workspace-write`; `approvalPolicy`, default `ask`). + +`createApiProxy` owns the approval pending registry.

A permission-less composition serves an empty select and clients hide the control. Idle switches are held last-write-wins in a proxy-side pending map and flushed on `agent/prompt-submit`, because knob events must stay turn-enclosed for durable replay; the shared `hasOpenTurn` fold moved to `dsh-session` and replaced the private copies in `dsh-user-approval`, the ACP bridge, and the proxy. + +Client-side, `Session` gained `permissions` and `setPermission`, and approval answering rides the runtime's `PendingWait` carrier. Per the designer draft, a pending approval takes over the composer: `ApprovalPanel` registers as a selector-routed entry of the conversation-declared `conversation.composer` chain (the ui-question pattern), replacing the InputBar with the justification headline, the paired command, and one-shot refuse/allow buttons; the `PendingApproval` domain face in ui-conversation's contract owns the `ApprovalResponsePayload` wire encoding over the carrier, and the broadcast resolved frame settles the wait and restores the composer. Question placeholders stay in the message flow. The sidebar mirrors the blocked state with an amber warning dot that outranks the running ring: the manager tracks per-session outstanding approvalIds (idempotent under mux-open replays, cleared per connection generation so the reopen replay is authoritative) rather than reading Session instances, so the dot lights for sessions never instantiated.

Publishing those intermediate observations as authoritative empty catalogs would be worse than retaining the last complete view. + +## Decision + +The skill capability separates catalog membership from instruction-body loading. `ctx.skills.snapshot()` returns summaries plus a completeness bit. `ctx.skills.registerProvider(factory)` gives the synchronous factory one registration-scoped `{ signal, invalidate }` control: `invalidate()` dirties only that exact active registration and discards completed catalog caches, while the signal aborts when registration fails or is disposed. Provider arrays are complete-discovery shorthand; an explicit incomplete observation can retain readable candidates for direct loads without becoming cacheable or authoritative for model-facing consumers. A provider or runtime generation change during discovery retries once; if the retry is also superseded, the latest candidates return as an incomplete, uncached observation. A late invalidation after disposal or replacement is a no-op because the capability has been revoked. + +`@deepseek-ai/dsh-skill-local` directly depends on Chokidar and observes catalog-relevant host paths. Existing roots watch direct skill bundle directories, flat Markdown entries, and direct `SKILL.md` entry files. Additions, removals, and directory changes invalidate membership; file changes support frontmatter `name` and `description` refresh. Resource files below a bundle are ignored. Events in one microtask batch coalesce to one invalidation. Project watchers use a bounded least-recently-observed set. + +A missing root is followed from its nearest existing ancestor one absent segment at a time with `fs.watchFile`, then handed to Chokidar once the real root exists. Before scanning, each discovery re-probes the retained root/ancestor mode. That independent probe re-establishes ancestor observation after deletion even when child removals invalidate and publish an authoritative empty catalog before, or without, a root `unlinkDir` event. Chokidar configuration exposes native-versus-polling mode, write stability, polling interval, symlink following, and project watcher capacity. First-party `write` and `edit` tool observations synchronously invalidate a relevant provider, so the next model step sees its own mutation without waiting for host delivery. Watch startup/runtime failures are logged and retried; discovery still returns readable candidates for direct loads but reports an incomplete observation. Teardown closes watchers and ignores late callbacks. + +`@deepseek-ai/dsh-tool-skill` injects the first non-empty complete catalog as a durable sourced `user/message` on the first complete `agent/step` that observes one. At every `agent/step` it applies exact `skill` tool visibility, hashes the exact rendered text between the `` tags, and scans the read-only session events backwards without copying them for the newest recognizable visible catalog from this plugin. A changed digest appends a durable, complete replacement through `agent.inject()`, including an explicit empty catalog when all skills disappear. If no catalog remains visible but a recognizable one exists in historical events, compaction hid it and the next complete observation re-establishes the current catalog, including an empty tombstone. A current empty catalog with no historical publication emits nothing, while an incomplete snapshot preserves the last-good model view. The backward scan normally stops at the newest visible catalog; when compaction hides every catalog it pays an O(session-events) scan to recover that fact. + +The TUI consumes the same invalidation as presentation state, not session history. `skills/change` carries no diff; the TUI refetches `snapshot()` for the active session cwd, applies only the latest complete result, and retains the previous commands across incomplete observations. A complete empty result clears stale completions. Because pi-tui closes autocomplete when its provider is replaced, a catalog that arrives while the user is typing a slash-command name also triggers a suggestion-only re-query of the current draft. + +Instruction bodies keep progressive disclosure. Every `skill(name)` call asks the provider to reread and parse the current file; there is no body cache, hash, revision, or proactive notification. Previously logged tool results remain unchanged. If the loaded frontmatter name no longer matches the selected candidate, the registry rejects the stale name and invalidates that provider so a later catalog observation can publish the new name. + +## Verification + +Registry tests pin registration-scoped invalidation, revocation, signal abort, contained observer failures, incomplete candidates, bounded generation retries, and stale-name rejection. Local-provider tests cover bundle and flat-file creation, removal, rename, root creation/deletion/recreation including an unobserved root `unlinkDir`, description changes, body-only edits, first-party observation, symlinks, polling options, persistent watcher failures with loadable candidates, event coalescing, bounded projects, teardown, and transient reads. Tool tests pin full replacement messages, empty tombstones, digest stability for body-only edits, incomplete-state retention, visibility, and resume metadata. TUI tests pin last-complete retention, authoritative empty removal, latest-wins refresh, teardown, and the already-open slash-draft race; a real Loader/PTY smoke adds a local skill after startup and observes its completion without restarting. A keyless assembled agent-spine snapshot creates a project skill through model-facing filesystem tools, observes its replacement catalog on the next request, and loads its current body with the real `skill` tool. + +## Alternatives considered + +- **Put the live catalog in World State** — rejected because catalog replacements are model-visible session inputs and must be reconstructable from the event log. Durable injected history already provides replay, resume, fork, and compaction semantics without another mutable state plane. +- **Rely only on `fs/observed`** — rejected because IDEs, Git, shell commands, and external processes do not cross that seam. The event remains a latency fast path for first-party tools, while host watching supplies coverage. +- **Hash or version every `SKILL.md` body** — rejected because the model initially sees only names and descriptions, and the provider already rereads the body on each tool call. Body revisions would create catalog traffic without changing routing and would not justify rewriting historical tool results. +- **Watch every bundle resource** — rejected because references, scripts, and assets are loaded on demand and do not affect the category list. Broad recursive watching would add invalidations, descriptor pressure, and platform variability without improving routing. +- **Publish partial or failed discovery as the new catalog** — rejected because a transient read failure is not evidence of deletion. The completeness bit lets the model-facing consumer preserve its last-good catalog until a full observation succeeds. +- **Keep `invalidateProvider(provider)` public** — rejected because it exposes a registry mutation method and makes callers resupply an identity the registry already owns. The factory-issued closure binds invalidation to one registration and becomes inert on disposal, so observers need neither registry access nor provider identity. +- **Extract a generic Cordis file-watching service now** — deferred until another consumer establishes the reusable service contract. The local provider marks its Chokidar and missing-root observation boundary for that extraction; skill-path filtering and the call to the provider's invalidation closure remain skill-specific. + +## Consequences + +- New, deleted, and renamed local skills become visible at model-step boundaries without restarting the agent, including when the skills root did not exist at startup. +- The TUI's `/skill:` completions converge on the same complete catalog without blocking each keystroke on discovery; an open slash-name draft refreshes when the catalog arrives. +- Catalog messages are append-only, logged, whole-list snapshots.

A user directing several panes wants the model to orient itself to its own location so instructions like "the pane below" or "this window" resolve. The location must reach the model as durable, reconstructable context, not a system-prompt value rewritten in place, and must cost nothing when the location has not changed. + +tmux exposes this without a daemon: `$TMUX_PANE` names the process's pane, and `tmux display-message -t "$TMUX_PANE" -p ''` prints any pane/window/session field. The open question was how to observe it — pull on each preparation, or push from a tmux hook — and how to avoid a per-step token cost and hidden process-local state. + +## Decision + +`@deepseek-ai/dsh-tmux-context` is an opt-in function plugin in `packages/context/tmux-context/`, alongside the other bounded request-context enrichments that define neither a tool nor a service. Shipped examples do not mount it because tmux-location disclosure and its token cost are deployment policy. + +**Pull on the first step of each turn, not a tmux push.** The plugin prepends an `agent/step` listener and acts only when `step === 1`. A pull model needs no background process, no hook installation in the user's tmux, and no teardown; it re-reads current state each turn so a moved, renamed, or re-laid-out pane is picked up naturally. Gating on the first step makes the reading per-turn: a location is stable within a turn, and re-querying every step would add cost without new information. A pane moved mid-turn is reflected on the next turn, which is the accepted tradeoff for the simpler design. + +**Read through the `ctx.bash` seam, never raw `child_process`.** The listener runs the tmux/`ps` read commands through `ctx.bash`, so the deployment's sandbox and policy apply and the plugin owns no subprocess code. Absent `ctx.bash`, absent tmux env, a wrong field count, or an empty pane id each make the attempt a no-op, matching how `workspace-context` no-ops without an `fs` provider. + +**Detect a real pane by tty, not by `$TMUX_PANE` alone.** `$TMUX_PANE` is inherited: a terminal launched from a tmux shell (a VS Code integrated terminal, a desktop launcher) carries `$TMUX`/`$TMUX_PANE` from that ancestor even though the process does not live in that pane, which otherwise injects a stale, wrong location. The command resolves this process's controlling terminal with `ps -o tty= -p ` (the agent's own pid, passed in-process) and compares it to the pane's `#{pane_tty}`; fields are emitted only on a match. A genuine pane owns this process's tty; an inherited environment names some other pane's tty and reads as "not in tmux". Checking `$TMUX` instead does not help — it is inherited identically. This is the definitive discriminator and needs no allowlist of terminal emulators. + +**Own location and layout only.** The queried fields are session name, window index/name, pane index/id, window/pane active flags, and `window_layout`. Pane and window pixel sizes are excluded (layout tree conveys structure; sizes are noisy and change on every terminal resize). Sibling-pane contents are never captured (`capture-pane`), keeping the reading small and avoiding scraping unrelated, possibly sensitive, output. + +**Inject only on change, with optional interval floor.** When due, the plugin calls `agent.inject()` for one `user/message` with source `{ kind: 'plugin', plugin: 'tmux-context' }`. Change suppression compares the rendered state block (everything after the turn preamble line) against the latest injection of this source, found by scanning raw durable session events — so the schedule survives compaction and process resume without a process-local cache. The optional `refreshIntervalMs` (manually validated as a non-negative safe integer at plugin load) additionally suppresses injections within that window of the latest one. + +### Text + +```text +tmux location (turn ): +session , window "", pane +window active=<0|1>, pane active=<0|1>, layout +``` + +The turn preamble is the volatile first line; the two-line state block below it is the unit compared for change suppression, so re-injection is driven by tmux state, not loop position. + +### Durability and request reconstruction + +Each reading is a normal surface node until compaction shadows it; the plugin contributes nothing to system-prompt assembly and `request/header` carries no tmux-context text. The reading records a preparation attempt, not a committed step: because the prepended listener runs first, its append may remain when a later `agent/step` listener cancels or fails the attempt, and the append-only log performs no rollback. + +The published `./invariant` companion registers no runtime check: a reading is a per-turn snapshot of external tmux state, so the session holds no cross-event relation to validate, and scheduling and format stay pinned by the package's pipeline tests. + +## Consequences + +An agent booted inside tmux now receives its own session/window/pane location and window layout as durable, source-attributed context, updated per turn when the location changes. Deployments opt in through cordis.yml; the default spine and shipped examples stay silent. Outside a real tmux pane — including a terminal that merely inherited `$TMUX`/`$TMUX_PANE` — or without a `ctx.bash` executor, the plugin is inert with no error, so composing it is safe everywhere. Because the reading is one durable `user/message`, it survives compaction as ordinary history, contributes nothing to system-prompt assembly or request headers, and costs at most one two-line message per changed turn. The pull model adds one `tmux display-message` subprocess (through the sandboxed bash seam) on the first step of each turn that is due. The optional interval floor is checked before the query and so suppresses both; an unchanged location is detected only by comparing the returned state, so it suppresses the injection while still paying for the query. + +## Testing + +Unit tests pin: first-step injection and source/surface metadata; the `$TMUX_PANE`-keyed command including its `#{pane_tty}`-vs-`ps -o tty=` guard; step-gating; change suppression across turns and re-injection on a moved pane; positive-interval suppression and threshold; every no-op path (no bash, nonzero exit, wrong field count, empty pane id, aborted signal, and a contained executor rejection from either `resolve()` or `run()` that warns instead of failing the turn); prepended ordering before ordinary `agent/step` listeners; resilience to a corrupt prior reading (non-text block, single-line text); and config rejection of negative and non-integer intervals. Per-file coverage is 100%. + +## Alternatives considered + +- **Push from a tmux hook / background watcher** — rejected: requires installing hooks in the user's tmux and a background process with teardown, to gain mid-step freshness that per-turn context does not need. +- **Run every step** — rejected: location is stable within a turn; re-querying adds token cost without new information. Gating on `step === 1` yields per-turn readings. +- **Raw `child_process`** — rejected: bypasses the sandbox/policy seam and hand-rolls subprocess code the `ctx.bash` executor already owns. +- **Include pane/window pixel sizes** — rejected: sizes churn on every resize and add noise; the layout tree already conveys structure. +- **Scrape sibling panes with `capture-pane`** — rejected: large, noisy, and privacy-sensitive; out of scope for "own location". +- **Dynamic system-prompt section** — rejected: replacing a value erases the earlier readings behind prior reasoning and is not reconstructable; one durable attributed message records each location where it became visible. +- **Trust `$TMUX_PANE` (or `$TMUX`) presence** — rejected: both are inherited by terminals launched from a tmux shell (VS Code integrated terminal), so a non-pane process injects a stale location. The pane `#{pane_tty}` vs. this process's controlling tty is the definitive check. +- **Denylist known terminal emulators (e.g. `TERM_PROGRAM=vscode`)** — rejected: a partial, ever-growing list that still misses other launchers; the tty match is exact and launcher-agnostic. +- **A runtime invariant validating each reading's turn, position, and format** — shipped initially, then removed: it re-derived the producer's own scheduling from the log and asserted a regex over text the same package had just rendered, so it restated `apply()` rather than checking an independent relation. Every failure it could report required an edit to this package, which its pipeline tests already catch. Reintroduce a companion check only for a relation the plugin does not itself compute — for example if readings gain cross-turn ordering or enclosure obligations that another package can violate. diff

Turn boundaries use a slightly heavier rule, the raw Turn id, and a continuous left rail; Request boundaries appear as small points integrated into that structure and use one chronological numbering space across ordinary and compaction requests. +- Event kind and content form the two stable columns. Role tags align toward the content, nested subtools receive a small indentation, and CSS truncation preserves the available preview width. Token usage and duration stay in the inspector. +- Product prose uses the existing sans stack. Turn ids, token counts, durations, tool calls, raw payloads, and other machine data use the existing code stack. +- Existing theme tokens own both light and dark rendering. Neutral borders and surfaces form the structure; distinct low-emphasis role hues support scanning without carrying success or failure meaning, while business blue identifies selection, links, and focus. +- The client runtime exposes a read-only history source independent from Session and SessionManager. Each activated source owns its raw entries, paging, live gap repair, and reconnect rebuild; the ordinary conversation snapshot remains the folded Chat projection. Trajectory subscribes to that source, exhausts its paging only while mounted, and lazily derives its event order, context lineage, schema index, and Requests instead of imposing those structures on every conversation consumer. +- Ordinary generation and compaction calls form one chronological Request projection, distinguished by purpose rather than separate collections. Effective prompt state and its change ride the Request that introduced them; compaction and prompt changes are not independent inspection entities. Complete history makes global Request numbering and cumulative usage session-wide rather than tail-window-relative. +- Call schemas come from the active recorded Request header. Keyless snapshot fixtures deliberately replace that catalog with the non-array `{{tools}}` token, which the durable inspection boundary treats as unavailable instead of attempting to project or fabricate schemas. +- Selecting a record or Request opens an inspector inside Trajectory. Tabs and Summary sections follow the selected entity: Markdown messages expose rendered, source, provenance, and hierarchy views; tools add JSON payload/result and schema views; Requests add options, usage, timing, and result navigation. Images render as media rather than serialized data. +- Turn folding removes all rows after its first record and replaces them with a compact step/tool-call count; Assistant folding applies the same interaction to its tool-call descendants. Global controls fold or expand both levels. +- The separate Waterfall tab is removed. A fixed Overview above the ledger projects every record with known `startedAt` onto three semantic timing lanes using its own duration. Dragging left or right commits an inclusive interval filter: any record whose active interval overlaps either boundary remains visible, records without known timing leave the focused ledger, and clearing the selection restores the full branch. The Overview keeps the full time domain while focused so the selection can be resized or cleared without losing orientation. +- This local inspector remains independent from the conversation-wide Chat details column. At narrow widths it overlays the ledger and remains dismissible by keyboard or pointer. + +## Alternatives considered + +**Copy Vite DevTools fonts, colors, glass surfaces, or component shapes.** Rejected: those choices express a different product identity. The implementation only adopts the transferable method: neutral structure, semantic accents, machine-data typography, dense scanning, and shadows reserved for floating layers. + +**Keep one card per Turn and Step.** Rejected: repeated card chrome reduced the number of visible records and made cross-step comparison slower. + +**Flatten every record without Turn or Request boundaries.** Rejected: a trajectory is not merely a log stream; those boundaries preserve the causal structure without consuming dedicated rows. + +**Reuse the global Chat details column.** Rejected: it would couple local inspection to conversation navigation and make a row click unexpectedly change another view's state. + +**Keep timing in a separate Waterfall tab.** Rejected: the placeholder summarized node counts rather than record timing and forced users to switch away from the rows they wanted to focus. A full-domain Overview keeps timing and filtered records in one visual context. + +**Change global theme tokens to match the reference.** Rejected: the existing theme already provides paired light and dark semantic layers, and a local redesign does not justify changing unrelated surfaces. + +## Consequences + +Trajectory shows more useful records per viewport while retaining Turn and Request orientation. Context rewrites and compactions remain inline with their surrounding history, while a rewind begins a successor branch that inherits only the retained prefix. The main ledger omits token usage and duration so content receives the available width; the local inspector exposes those facts together with full payloads, provenance, schemas, and request timing. The Overview uses recorded start/duration facts without fabricating live elapsed time, and its inclusive focus behavior matches the interaction users already know from Chrome DevTools Network. Focused component tests pin projection, folding, record and interval selection, entity-specific tabs, and running/error semantics; the assembled Web snapshot pins the ledger, Overview, and inspector through the real client composition. diff --git a/.agents/notes/implemented/feature/2026-07-27-trajectory-inspection-ledger.zh.md b/.agents/notes/implemented/feature/2026-07-27-trajectory-inspection-ledger.zh.md new file mode 100644 index 0000000000..6c5733046d --- /dev/null +++ b/.agents/notes/implemented/feature/2026-07-27-trajectory-inspection-ledger.zh.md @@ -0,0 +1,43 @@ +# Agent Note：轨迹检查记录表 + +Status: implemented + +[English](2026-07-27-trajectory-inspection-ledger.md) | 中文 + +## 问题 + +轨迹视图需要在同一视口内清晰呈现正文、机器载荷、token 用量、计时数据和嵌套工具活动。此前堆叠式的轮次与步骤卡片虽然保留了层级，却在重复界面框架上耗费了太多垂直空间；完全扁平化的表格又会抹去因果结构，而这种结构正是轨迹视图的价值所在。角色配色还可能借用成功与警告语义，使视觉装饰与运行时状态无法区分。 + +## 决策 + +**使用现有 DeepSeek 设计系统，渲染保留轮次结构的紧凑事件记录表，并提供局部记录检查器。** + +- 记录表在以 `rewind` 划分的分支内按会话事件顺序展示。轮次边界由稍粗的分割线、原始轮次 id 和连续的左侧竖线表示；请求边界以融入该结构的小圆点表示，普通请求与压缩（compaction）请求在整个时间序列中共用一套编号。 +- 事件类型与内容构成两个稳定列。角色标签朝内容侧对齐，嵌套子工具略微缩进，内容预览使用 CSS 截断以适应可用宽度。token 用量和耗时留在检查器中。 +- 产品正文使用现有无衬线字体栈。轮次 id、token 数、耗时、工具调用、原始载荷和其他机器数据使用现有代码字体栈。 +- 现有主题 token 同时负责亮色和暗色渲染。中性边框与表面构成整体结构；区分度较低的角色色帮助扫读而不表达成功或失败语义，业务蓝色则标识选择状态、链接和焦点。 +- 客户端 runtime 提供独立于 Session 和 SessionManager 的只读历史数据源。每个已激活的数据源自行拥有原始条目、分页、实时缺口修复和重连重建；普通会话快照仍然只是 Chat 所需的折叠投影。Trajectory 订阅该数据源，仅在挂载期间补齐全部历史，并按需派生事件顺序、上下文谱系、schema 索引和请求，避免让所有会话消费者承担这些结构。 +- 普通生成调用与压缩调用形成一条按时间排序的请求投影，以 purpose 区分而不是放入不同集合。生效的提示词状态及其变化附着在引入它们的请求上；压缩和提示词变化都不是独立检查实体。完整历史使全局请求编号和累计用量以整个会话为范围，而不是相对于末尾窗口。 +- 调用 schema 来自当前生效且已记录的请求头。无密钥快照 fixture（测试前置数据）有意将该目录替换为非数组 token `{{tools}}`，持久化检查边界会将其视为不可用，而不是尝试投影或虚构 schema。 +- 选择记录或请求后，轨迹视图内部会打开检查器，其标签页和概览区域随实体类型变化：Markdown 消息提供渲染、源码、来源和层级视图；工具提供 JSON 载荷／结果和 schema 视图；请求提供选项、用量、计时和结果跳转。图片以媒体形式渲染，而不是显示为序列化数据。 +- 折叠轮次时保留其第一条记录，将后续行替换为紧凑的步骤和工具调用数量；折叠助手时对其工具调用后代应用相同交互。全局控件可以分别折叠或展开这两个层级。 +- 移除独立的 waterfall（瀑布式事件）标签页。固定在记录表上方的 Overview 区域将所有 `startedAt` 已知的记录按各自耗时投影到三条语义计时轨道。向左或向右拖动会提交包含边界的区间筛选：任何活动区间与所选区间相交的记录都会保留，计时未知的记录会从聚焦后的记录表中移除，清除选择则恢复完整分支。聚焦后，Overview 区域仍保留完整时间范围，以便在不失去方位的情况下调整或清除选择。 +- 此局部检查器与会话级 Chat 详情栏相互独立。在窄屏下，检查器会覆盖记录表，并且仍可通过键盘或指针关闭。 + +## 曾考虑的替代方案 + +**照搬 Vite DevTools 的字体、颜色、玻璃表面或组件形状。** 不予采纳：这些选择表达的是另一种产品身份。实现仅吸收可迁移的方法，即中性结构、语义强调色、机器数据排版、紧凑扫读，以及只为浮层保留阴影。 + +**每个轮次和步骤保留一张卡片。** 不予采纳：重复的卡片框架减少了可见记录数量，并降低了跨步骤比较的速度。 + +**不使用轮次或请求边界，将所有记录完全扁平化。** 不予采纳：轨迹并非普通日志流；这些边界无需占用独立行，也能保留因果结构。 + +**复用全局 Chat 详情栏。** 不予采纳：这会让局部检查与会话导航耦合，还会使行点击意外改变另一个视图的状态。 + +**将计时保留在独立的 waterfall 标签页中。** 不予采纳：占位实现汇总的是节点数而非记录计时，并迫使用户离开想要聚焦的记录。保留完整时间范围的 Overview 区域让计时和筛选后的记录处于同一视觉上下文中。 + +**修改全局主题 token 以匹配参考设计。** 不予采纳：现有主题已经提供配对的亮色与暗色语义层，局部重新设计不足以成为修改无关表面的理由。 + +## 后果 + +轨迹视图在保留轮次与请求定位的同时，每个视口可以显示更多有效记录。上下文 `rewrite` 与压缩保持在周边历史中的原始位置，`rewind` 则建立仅继承保留前缀的后继分支。主记录表省略 token 用量和耗时，让内容获得可用宽度；局部检查器展示这些数据以及完整载荷、来源、schema 和请求计时。Overview 区域使用记录的开始时间与耗时数据，而不虚构实时流逝时间，其包含边界的聚焦行为与用户熟悉的 Chrome DevTools Network 交互一致。针对性组件测试锁定投影、折叠、记录与区间选择、实体特定标签页和运行／错误语义；组装后的 Web 快照则通过真实客户端组合锁定记录表、Overview 区域与检查器。 diff --git a/.agents/notes/implemented/feature/2026-07-27-tui-tool-card-header.i18n.yaml b/.agents/notes/implemented/feature/2026-07-27-tui-tool-card-header.i18n.yaml index 820645dc95..ed6406245e 100644 --- a/.agents/notes/implemented/feature/2026-07-27-tui-tool-card-header.i18n.yaml +++ b/.agents/notes/implemented/feature/2026-07-27-tui-tool-card-header.i18n.yaml @@ -2,5 +2,5 @@ # side as of the last confirmed-consistent state.

Two independent causes produced that limit, and fixing either alone changes nothing. + +Storage was the binding one. The shipped TUI composition defaulted its persistence root to a relative `./.sessions`, so each launch directory owned a disjoint JSONL root and a disjoint derived `session-query.db`. Sessions from another project were not filtered out of the listing — they were absent from the store the listing reads. The JSONL backend already partitions per-cwd *inside* one root, so the partitioning was doubled: once by root, once within it. + +The picker then filtered again. It dropped records whose `cwd` differed from the current session before display, and `summarizeResumeCandidate` independently marked a differing `cwd` as `disabledReason: 'different workspace'`, so a foreign session that did reach the store was both hidden and refused. + +Finally, resume never changed directory. The host re-execs `dsh --resume=` through `process.execve`, which inherits the cwd. Session *header* cwd is restored from the log, but process cwd is what `dsh-fs-local`, the bash executor, and glob/grep resolve against, so resuming a foreign session would have replayed its transcript while acting on the wrong project. + +## Decision + +The shared CLI configuration supplies one session root under the Harness home, the picker gains a workspace scope, and the handoff carries the target directory. + +**Storage.** The shared base owns the default in `apps/cli/config/base.cordis.yml`: its `session-persistence-jsonl` row resolves `sessions` beneath `DSH_HOME`, with the standard `~/.dsh` fallback when the environment has not been initialized. TUI, Web, and headless therefore consume one default without launcher patches or a boot slot. An overlay or personal patch that states an explicit root replaces that row's whole `config` and remains the deployment's authoritative choice. + +**Scope, not exclusion.** A workspace other than the current one is a display scope rather than a disabled reason. `showResume()` summarizes every record and the `ResumePicker` owns a `scope` of `'workspace' | 'all'`, defaulting to the current workspace so the common case is unchanged. Tab toggles; the scope line names the active scope and the count the other holds; each row in the all-workspaces scope reports its own workspace, and that label joins the searchable text only in the scope that shows it. A toggle clears the query and selection so the highlighted row always belongs to the visible list, and the per-row workspace line makes a row one terminal row taller in that scope, which the visible-count budget accounts for. + +`summarizeResumeCandidate` therefore drops `'different workspace'` and gains `'session has no recorded workspace'`. That is a real new refusal rather than a rename: a header without `cwd` names no directory for the host to enter, so it cannot be handed off even though its log is intact. + +**Handoff.** `TuiResumeHost.handoff` takes the target `cwd` beside the `SessionId`. `preflightResume` resolves both together and returns them, so the caller cannot re-derive a stale directory from the row it displayed — a record whose `cwd` moved between listing and preflight is resumed in the *re-read* directory, which is why the former "reject a moved cwd" behavior is now a handoff with the new path. The shipped host chdirs before disposing the app: an unreachable directory must reject while the caller can still restore the terminal, because after teardown no owner remains to report to. Resume always uses the default `dsh --resume` surface because `meta` rejects parent options; the handoff already enters the persisted target directory. + +## Alternatives considered + +**Patch `persistenceRoot` from the `dsh` launcher instead of changing the bundle default.** Rejected after finding that a loader patch assigns `config` wholesale. The personal `~/.dsh/config.yaml` overlay already patches the `tui-agent` row with a partial config, which is exactly why `persistenceRoot` was falling back to the bundle default in the first place; a launcher patch would either be erased by that overlay or have to win over it and make the overlay unable to set the field. Owning the default in the bundle survives any partial patch and keeps one home for the fact. + +**Keep `./.sessions` and additionally scan the Harness-home root.** Rejected: two roots means two SQLite indexes and a merged listing whose rows have different liveness and revision authorities, to preserve visibility of logs that the no-migration decision already gives up. + +**Migrate existing project-local logs into the shared root.** Rejected by the requester. Sessions under a project's `./.sessions` stay on disk and stay resumable by explicit `dsh --resume ` from that directory, but no longer appear in `/resume`. + +**One flat list of every workspace.** Rejected: it loses the "this project" default that the overwhelmingly common case wants, and in a busy home directory the current project's sessions would compete with unrelated ones. + +**Let the host infer the directory from the restored session header.** Rejected: the header is model- and prompt-facing state restored *after* boot, while the directory must be entered *before* `execve`. Passing it explicitly keeps the ordering visible at the seam. + +## Consequences + +- Sessions already stored under a project-local `./.sessions` disappear from `/resume`. This is the accepted cost of no migration. +- A resumed session can change the process's working directory, so a foreign resume is not a pure transcript restoration — every path-resolving tool moves with it. +- The Harness home now holds session logs for every project on the machine. Its growth is no longer bounded by one checkout, and no retention policy is introduced here. + +## Testing + +TUI tests cover the default scope hiding other workspaces while reporting their count, Tab revealing them with per-row workspace labels, Tab back clearing the query and selection, searching by workspace label, a cwd-less record staying visible but disabled, and the handoff receiving both the id and the workspace re-read at preflight. The former "reject a moved cwd" case now asserts the handoff carries the new directory. Built CLI PTY tests exercise the shared config default and the per-process derived query index. The keyless TUI snapshot pins both scopes of the selector, including the scope line, the per-row workspace lines, and the Tab hint in the footer.

The cwd *is* the workspace seam in the shipped tree: `examples/tui-agent/cordis.yml` derives the session cwd (`!!js process.cwd()`), the `./.sessions` persistence root, and the HMR watch root (`root: ['.']`) from it, so one chdir moves all three together and meta sessions land in the checkout's gitignored `.sessions/`. It runs after both `.env` layers are loaded — the bin's invoking-directory load and the personal one — so the ambient > project > personal precedence is untouched. `DEFAULT_CONFIG` and `SOURCE_ROOT` are absolute and TUI mode passes no snapshot mode, so config resolution is chdir-independent. + +`meta` accepts only `--resume `. `--config` would boot a foreign tree against the harness workspace, which is the `--config` case rather than this one; `-p` is not interactive.

Launched from `$HOME`, a `pwd` tool call reports the checkout, git resolves to its branch, the session log lands under the checkout's `.sessions/` (leaving `~/.sessions` untouched and the tree free of unignored residue), and plain `dsh` from another directory still uses the invoking one. + +`dsh meta --resume ` once started a *fresh* session instead of resuming — a pre-existing defect on the default surface, not one this mode introduced. [Launcher-owned resume identity](../architecture/2026-07-28-launcher-owned-resume-identity.md) found the cause and fixed it: a personal overlay had replaced the whole `tui-agent` config block, overwriting the shipped `resumeSessionId` intake with a read of an unset environment variable, so a valid id was silently ignored.

TUI unit coverage exercises those quadrants plus disposal races, while registry, local-parser, model-tool, and API-proxy tests cover defaults, supported boolean forms, malformed values, legacy-key rejection, exact-load enforcement, and the browser intersection. diff --git a/.agents/notes/implemented/feature/2026-07-28-skill-invocation-policy.zh.md b/.agents/notes/implemented/feature/2026-07-28-skill-invocation-policy.zh.md new file mode 100644 index 0000000000..1a7117a382 --- /dev/null +++ b/.agents/notes/implemented/feature/2026-07-28-skill-invocation-policy.zh.md @@ -0,0 +1,50 @@ +# Agent Note: 模型与用户彼此独立的 skill（技能）调用策略 + +Status: implemented + +[English](2026-07-28-skill-invocation-policy.md) | 中文 + +## 问题 + +skill 注册表最初将发现操作视为模型目录：`ctx.skills.list()` 会移除禁止模型调用的 skill，而 `ctx.skills.get()` 仍是不过滤内容的可信 loader。该设计足以支持由模型发起的加载，却无法表示与 Claude 兼容的四类 skill：仅向用户公开、仅向模型公开、同时向两者公开，或者两者均不公开。TUI 从面向模型过滤后的列表中生成用户自动补全，并允许通过 `get()` 加载任意精确名称，这进一步放大了两类调用策略不匹配的问题。 + +本地解析器还将一种内部驼峰式拼写暴露为 frontmatter。若要支持既有的负向字段 `disable-model-invocation` 和正向字段 `user-invocable`，需要建立持久且对称的领域表示，同时避免把所有可能出现的 YAML 键都变成跨包的无类型契约。 + +## 决策 + +`SkillSummary` 包含一个必填且类型明确的 `invocation: SkillInvocationPolicy` 对象，其 `modelInvocable: boolean` 和 `userInvocable: boolean` 字段为正向且对称。只有显式输入 seam 可以省略它：未提供策略的运行时 `SkillRegistration`，以及两个调用键均未提供的本地 frontmatter，都会在生成候选项或定义前解析为 `{ modelInvocable: true, userInvocable: true }`。未来的 frontmatter 键只有在具备消费方和执行契约后，才会进入领域模型；本地提供方仍将 frontmatter 解析为开放的 `Record`，然后只把已识别字段及其默认值投影到规范化的类型化策略中。 + +`ctx.skills.list()` 返回所有胜出的摘要，不再替任何调用接口选择策略。`isModelInvocable(skill)` 和 `isUserInvocable(skill)` 分别直接读取对应的正向字段。`ctx.skills.get()` 保持策略无关，因为可信内部调用方可能需要任意定义；对外消费方则必须在展示或加载 skill 之前执行自身对应的判定函数。模型工具和 TUI 会在调用 `get()` 前检查与调用策略无关的摘要，随后再次检查已加载的定义：被拒绝的名称绝不会进入定义加载流程，发现与加载之间发生策略变更也无法暴露该 skill 的正文。 + +本地提供方只接受拼写完全一致的 kebab-case frontmatter 键 `disable-model-invocation` 和 `user-invocable`。它接受 YAML 布尔值，以及不区分大小写的 `true`/`false`、`yes`/`no`、`on`/`off` 和 `1`/`0`，与 Claude skills 实际支持的布尔写法一致。它将 `disable-model-invocation` 映射为相反的正向字段，即使两个键都不存在，也会根据默认值填充两个正向字段。若使用外部驼峰式拼写或提供非布尔调用值，发现流程会丢弃整个 skill，并给出有针对性的警告；本仓库尚处于发布前阶段，因此不为磁盘格式保留兼容别名。调用数据校验遵循失败时默认拒绝原则，因为忽略这类数据会默认授予权限，可能使 skill 暴露在已禁用的接口上；与之不同，类型错误的可选 `whenToUse` 和 `metadata` 值会被省略，因为它们不参与调用判定。 + +面向模型的 `dsh-tool-skill` 目录和 loader 执行 `isModelInvocable`。TUI 的 `/skill:` 自动补全与精确名称 loader 在本地执行用户字段，因此仅允许用户调用的 skill 即使不出现在模型发现结果中，仍会在此处显示并可加载，同时不会将可选的 skill peer 变成运行时导入。由 launcher 预置、供引导式 `dsh migrate` 和 `dsh upgrade` 会话使用的初始 skill 沿用同一条 TUI 路径，因此必须保持允许用户调用。浏览器的 `skill.list` RPC 提供的是由用户选择、但仍要求模型加载的引用，因此只公开同时允许模型和用户调用的 skill；本次改动不新增让浏览器直接加载 skill 的 RPC。 + +这些规则允许以下四种组合： + +| 策略 | 模型侧接口 | 用户侧接口 | +|---|---|---| +| `{ modelInvocable: true, userInvocable: true }` | 包含 | 包含 | +| `{ modelInvocable: true, userInvocable: false }` | 包含 | 排除 | +| `{ modelInvocable: false, userInvocable: true }` | 排除 | 包含 | +| `{ modelInvocable: false, userInvocable: false }` | 排除 | 排除 | + +该决策扩展了 [skill 系统](2026-07-05-skill-system.md)，并取代 [TUI skill 斜杠命令](2026-07-21-tui-skill-slash-command.md)中记录的调用策略限制。 + +## 曾考虑的替代方案 + +**将所有 frontmatter 存入通用 `Map`，并在 `isModelInvocable` / `isUserInvocable` 中读取字符串键。** 不予采纳，因为拼写错误的键、非布尔值以及各消费方自行采用的类型转换都会越过包边界，且无法获得类型检查。解析器边界仍保持开放；领域模型则有意采用类型明确的窄接口。 + +**保持 `ctx.skills.list()` 仅返回允许模型调用的 skill，并另增一份用户列表。** 不予采纳，因为发现、重复项解析、缓存和排序都是与调用接口无关的工作。采用一份完整目录和显式判定函数，可以避免这些机制逐渐分化，并在各消费方边界清楚呈现其策略。 + +**在 `ctx.skills.get()` 内执行调用策略。** 不予采纳，因为 `get()` 无法判断调用方是模型工具、人类命令还是可信编排逻辑。在此处过滤还会使两个接口均禁止调用的组合无法被检查或管理。 + +**将驼峰式 frontmatter 作为别名处理。** 不予采纳，因为外部格式遵循采用 kebab-case 的 Claude skills 契约，而本仓库尚未发布，无需承担兼容义务。快速失败可以避免暗中保留不符合标准的拼写。 + +**增加由浏览器端直接调用 skill 的 RPC。** 本次改动不予采纳，因为现有浏览器流程插入的是模型引用，而非已经加载的指令正文。因此，该流程应当取模型与用户调用策略的交集；直接由用户加载的接口需要单独设计协议与日志记录方式。 + +## 后果 + +提供方与运行时注册对外提供小而类型明确的调用契约，同时本地 YAML 仍可扩展。每个新的发现消费方都必须明确选择模型判定函数、用户判定函数、两者的交集，或可信且不过滤的访问方式；如果遗漏这项选择，评审时可以直接看出问题，而不会再被注册表行为掩盖。 + +无密钥 ACP（Agent Client Protocol）快照固定了模型目录的变更：其中包含仅允许模型调用的 skill，并排除仅允许用户调用的 skill。组装后的无密钥 TUI 快照按精确名称发现并加载一个仅允许用户调用的 skill，随后在加载正文前拒绝一个仅允许模型调用的 skill；真实 Loader/PTY 冒烟测试通过随产品交付的终端进程证明了同一条仅允许用户调用的路径。真实宿主上的 Chromium 快照固定了浏览器在全部四种策略组合下的交集行为。TUI 单元测试覆盖这些组合以及资源释放竞态；注册表、本地解析器、模型工具和 API 代理测试则覆盖默认值、支持的布尔写法、格式错误的值、旧键拒绝、精确名称加载时的策略执行，以及浏览器侧的策略交集。 diff --git a/.agents/notes/implemented/feature/2026-07-28-todo-plan-clears-on-next-turn.i18n.yaml b/.agents/notes/implemented/feature/2026-07-28-todo-plan-clears-on-next-turn.i18n.yaml new file mode 100644 index 0000000000..b6390dffbf --- /dev/null +++ b/.agents/notes/implemented/feature/2026-07-28-todo-plan-clears-on-next-turn.i18n.yaml @@ -0,0 +1,6 @@ +# Bilingual-pair consistency record (docs/i18n/README.md): the git blob hash of each +# side as of the last confirmed-consistent state.

` with `white-space: pre-wrap; word-break: break-word`. Two defects followed from soft-wrapping and from having no height bound: multi-column output (`ls`, a table, box drawing) folded into a paragraph and lost the column alignment that is the whole point of that output, and a long single-column listing stretched the details panel to the length of the listing.
+
+## Decision
+
+`TerminalBlock` is a `ui-primitives` component that renders a shell command as a terminal surface, and both Web render sites for a bash call consume the terminal render intent through it: the chat tool row's expanded body and the details panel's Output section. `ui-conversation/src/client/contract/terminal-card-model.ts` is the single place that turns the snapshot's `callView`/`resultView` pair into the component's props, so the two sites cannot disagree about a command, its cwd, or its exit status. It returns null — the generic path — whenever neither side declares `card: 'terminal'`, including a `card` value this client version does not know, and whenever a settled call's result view is generic, which is how the bash tool's execution errors and background starts keep their existing rendering. Two duties the render-intent contract assigns to the UI bridge land here rather than in the tool: a settled result's `title` REPLACES the pending one, and the working directory resolves against the session workspace — an absolute view cwd is used as-is, a relative one joins under the workspace, and an omitted one IS the workspace, which is the common case for a bash call with no `workdir`. A pure presenter cannot see the session cwd, which is why the resolution belongs at this seam; each render site supplies the cwd off the session list row. Only a PRESENT call view can mean "omitted, so use the workspace": when the paging window drops the call head there is no cwd anywhere — the result view carries none — and the original call may have used an explicit workdir, so the prompt draws a bare `$` rather than naming a directory it cannot know. The resolved path also normalizes its `.`/`..` segments, because the bash executor resolves the workdir before running: a `..` against `/w/app` runs in `/w`, so the prompt label has to read `w` rather than `..`. A UNC path's `server` and `share` are part of its root rather than poppable segments, since Windows cannot climb above a share. The call view's `description` rides the same derivation, since the contract renders it above the card and it must outrank the row's args-derived summary. All three render sites draw it: both chat-row shapes and the details panel. An expanded row draws it itself, because the collapsed summary is hidden while a row is open — without that the description would only ever be visible collapsed, which is the opposite of what "above the card" means.
+
+The component's contract:
+
+- **Prompt lines, one per command line.** Each line of the command gets its own row: label, then that line verbatim. A `command` carrying two shell commands on two lines therefore reads as the two commands it is, instead of collapsing into one ellipsized row. The label is the cwd's last path segment, or `~` when the cwd equals the `home` prop — a browser has no `$HOME`, so the caller supplies the absolute home directory and the collapse simply does not apply without it. A view with no cwd renders a plain `$`. A trailing newline is a terminator, not an empty final command. Only the FIRST row carries the label: the view knows one working directory — where the call started — and a later line may run somewhere else entirely, since a `cd` in the command is enough to move it. Repeating the label down the rows would state a directory per line that nothing here knows, which is the same reason the run-state dot appears once. Later rows keep a bare `$` so they still read as prompts.
+- **One run-state dot for the call, on the first row.** `StateDot` in three of its four states: the chase while running, red for the exit status that also renders the pill, green for a clean settle — the same indicator a tool row's leading icon uses, so a row and its own card cannot disagree about one command. The dot exists because the first question a reader has about a shell command is whether it is still running, and without it that had to be inferred from the absence of output — which a settled command producing no output also looks like. It sits out of flow in a gutter the card reserves as its OWN left padding, so it neither indents its command nor depends on the command's text metrics to line up. The reservation is padding rather than margin because every render site rewrites `margin` wholesale to set its own indent, which silently cancelled a margin-based gutter and let a container clip the dot. Exactly one dot, whatever the line count: the exit status the view carries is the whole call's, and bash reports no per-command status, so a dot per line would assert of a line that succeeded inside a failing call that the line itself failed. The single visually hidden text label carries the same scope, since `StateDot` is `aria-hidden` and one label per row would read to assistive technology as several distinct outcomes.
+- **No soft wrapping.** Output lines are `white-space: pre` inside a horizontally scrolling box. Column alignment survives; a long line scrolls instead of folding.
+- **Height cap with an expand control.** Output longer than `DEFAULT_TERMINAL_MAX_LINES` (16) lines shows `ceil(max/2)` head lines plus the remaining tail lines, with a button in between that reports the hidden count and expands. The count is of parsed lines after the trailing output terminator is dropped, so an N-line output ending in a newline is N lines. The split arithmetic is the same as the TUI transcript's collapsed tool card (`packages/ui/tui/src/components/transcript.ts`), so one command's head and tail slices agree between the two front ends.
+- **ANSI color.** `anser` splits the SGR runs; `ui-primitives/src/ansi.ts` resolves each run into an inline style rendered as React spans. A foreground-only run maps the basic 16 colors onto `--dsw-*` theme tokens so authored color stays legible under both themes; a run that paints its own background keeps anser's literal rgb for both so its intended contrast survives, as do 256-palette, truecolor, and the two basic colors this design system has no token for. Sequences that carry no color (OSC strings, non-CSI escapes, inert C0 controls) are stripped before parsing so they never reach the DOM as literal characters. Cursor movements resolve before that strip, into a per-line column buffer rather than by string surgery, because carriage return and backspace only MOVE the cursor — neither erases anything, so what a reader sees is whatever each column last had written to it. `100%` then a carriage return and `OK` shows `OK0%`, since the redraw is shorter than the frame beneath it; a trailing `abc` plus a backspace still shows `abc`, since nothing overwrote the `c`; `abc` plus two backspaces and `XY` shows `aXY`. Each of these was checked against a real terminal, because the earlier truncate-and-delete approximations looked right and were not. SGR state is stamped per column as a terminal stores it per cell, so a partial overwrite keeps each surviving character's own color: red `bad`, three backspaces, then `ok` shows `okd` with the `d` still red. A CSI sequence occupies no column and changes only the state later writes are stamped with, which is also why a carriage return does not reset color, and why SGR state threads from one line to the next rather than closing at each newline. Erase-in-line is part of the same replay, because `\r\x1b[K` is the single idiom every spinner and progress bar writes — modelling the `\r` alone left the previous frame's tail standing, which is text the terminal never showed. Only `m` accumulates into a cell's style; a cursor or erase sequence must not, or the state string grows per redraw and emits boundaries anser has to discard. SGR is held per cell as a NORMALIZED record (foreground, background, attribute set), not as the sequence history: accumulating raw sequences made every state boundary re-emit the whole chain, so output that switches color without a full reset emitted O(n^2) characters — 3200 such cells produced 25 MB and a `RangeError` well under bash's own output cap. The record also lets the attribute closers every chalk-based tool writes (`39`, `49`, `22`, `24`, …) actually close their attribute, and each boundary emits one canonical sequence for the state it opens. A run also has to CLOSE: the replay converges to the state the scan ended in, not the last written cell's, because a reset after the final write changes no cell yet ends the run — without that a line finishing in `\x1b[0m` leaked its color onto every later line. The cursor advances by terminal columns, so a tab reaches the next 8-column stop, a wide character takes two (its spacer blanking rather than closing the gap once the lead cell is overwritten), and a combining mark takes none. Width follows emoji PRESENTATION rather than the U+2600-U+27BF block: `\u2713`, the check every progress line writes, is one column, so treating the block as wide misaligned exactly the output this card exists for. Writing over either half of a wide pair blanks the other, since a terminal cannot leave one cell of a two-cell glyph standing: `a\tb` then a redraw of `XY` shows `XY      b`, since a two-character redraw cannot reach column 8.
+- **Exit status and copy.** A non-zero exit code or a signal renders a status pill, matching the exit-status distinction the bash tool's own renderer draws; a clean exit renders none, and settled empty output renders a dimmed placeholder — judged on the parsed lines the card renders, not on the raw text, since output that is only escapes or control bytes survives a `trim()` yet parses to nothing visible and would otherwise draw blank rows plus a copy control for invisible bytes. The copy control copies the raw output text, not the rendered tree, so the prompt line and the pill stay out of the clipboard.
+
+Geometry, radius, and fonts mirror `CodeBlock`, so a terminal card and a fenced code block match visually; `white-space: pre` plus horizontal scroll is the deliberate divergence. The clipboard write both components need moved out of `CodeBlock` into a package-internal `src/clipboard.ts`, unexported so it stays an implementation detail of the two blocks.
+
+### Inline output in the chat row reverses a stated convention
+
+`chat/ToolRow.tsx` and `contract/tool-call-model.ts` asserted "no inline output ever — full results live in the details panel". Showing the terminal block in the row reverses that, on the owner's explicit decision.
+
+The reason the reversal holds: for a shell command the output *is* the result the user is reading, so routing it exclusively to a panel makes the common case a two-step interaction. A bounded, height-capped, non-wrapping terminal block in the row is what makes a bash-heavy transcript readable in one pass. The old rule's actual concern was a row whose height was unbounded by the length of the output, and the height cap plus expand control is what keeps that from returning.
+
+The remaining bound: the row caps at `CHAT_TERMINAL_MAX_LINES` (8), half the primitive's default, which the panel keeps — the message flow is a summary surface read across many calls, the panel is the single-call reading surface. Only the terminal intent renders inline; a generic tool's content is still panel-only.
+
+One premise of that split has since weakened: [tool rows stopped being details-panel click targets](2026-07-28-tool-call-file-open-in-os.md) and nothing replaced the gesture, so the panel is currently unreachable in the assembled application. The in-row cap is therefore the only surface a reader actually has for a long output, which the expand control covers. Restoring a panel entry point is that change's follow-up, not this one's — but until it lands, "the panel stays the place for the full output" is not true, and the row's expand control carries that load alone.
+
+## Alternatives considered
+
+**Render the terminal block only in the details panel.** This keeps the stated no-inline-output convention and needs no reversal to record. Rejected by the owner's explicit decision: a shell command's output is what the user came to read, and putting it one click away costs more than the convention buys. Recorded here as the owner's call, not as a conclusion derived from the codebase.
+
+**Reuse `CodeBlock` with a `console` language instead of a new primitive.** Rejected: `CodeBlock` soft-wraps, which is the defect being fixed, and it has no exit status, no cwd prompt line, no height cap, and no ANSI handling. Adding four terminal-specific concerns to the shared code-fence component would impose them on every markdown fence. The two components share their geometry and font tokens instead, which is the only part where one implementation is correct for both.
+
+**Hand-roll the SGR parser.** Rejected: an SGR parser is exactly the surface [prefer maintained dependencies over hand-rolling](../process/2026-07-26-dependencies-over-hand-rolling.md) says not to own — its edge cases (256-palette and truecolor forms, `reverse`, multi-parameter runs, unterminated sequences) each fail on output nobody produces in a test, so a hand-rolled version stays subtly wrong for a long time. Stated honestly against that policy's bar: `anser` does **not** delete existing owned code. It is a capability addition, which that note distinguishes from a net-deletion simplification; the health and boundary-fit halves of the bar are what it clears. What stays hand-rolled is the part `anser` does not cover: the theme-token color mapping, the non-CSI sanitizing, the carriage-return redraw, and the per-line span folding the height cap slices.
+
+## Consequences
+
+`anser` is a new runtime dependency of `packages/client/ui-primitives`, so every consumer of that package pays for it once. A bash row in the Web chat carries output, which is a deliberate density increase over a summary-only row; the cap is what keeps it bounded, and a tighter cap is a props change, not a redesign.
+
+`TerminalBlock` reads only the terminal view's fields, so it stays a pure function of what the render intent carries — no session lookups, replay-safe like the presenters that produce the view. A UI without the terminal capability still gets the bridge's fenced fallback; nothing about the tool's result shape changed.
+
+A `run_code` sub-dispatch does not reach a terminal card on the shipped wire: `session.ts` folds `tool/code-dispatch(-start)` with `callView: null`/`resultView: null`, and the host's `viewFor` presents only top-level `tool/call`/`tool/result`, so a nested bash call keeps the generic flattened form. Both arms are pinned — the resolution path with views injected, and the no-view shape the wire actually delivers — so the gap is recorded rather than implied. Carrying presenter views through the code-dispatch wire is that seam's own change.
+
+Inline rendering is licensed for the terminal intent alone. A future intent that wants it needs its own bound and its own decision, argued against the reason recorded here rather than against the panel-only convention on its own.
+
+## Testing
+
+`packages/client/ui-primitives/tests/ansi.spec.ts` pins the parse layer: token mapping for the basic colors, literal rgb for the values with no token, the background-run pair, every decoration and the `textDecoration` collision between two of them, the sanitizing of OSC strings and non-CSI escapes and inert controls, the cursor replay (redraws leaving a longer frame's tail standing, a trailing backspace erasing nothing, erase-in-line in all three parameter forms, tab stops, wide characters, SGR threading across lines, and a cursor/erase sequence never entering a cell style), and CRLF preservation. Each replay case was checked against a real terminal first. `packages/client/ui-primitives/tests/terminal-block.spec.tsx` pins the component: cwd shortening, the running/empty/settled arms, signal outranking exit code, the trailing-newline terminator rule, the head/tail cap with its `aria-expanded` toggle, the run-state dot across all three reachable states plus its position ahead of the prompt label, the one-row-per-command-line prompt and its single dot on the first row, and the copy control asserting raw output on both the accepted and refused clipboard paths, plus `writeClipboard` directly.
+
+`packages/client/ui-conversation/tests/terminal-card.spec.tsx` pins the wiring at every render site: `terminalCardModel`'s derivation and each of its null arms, the result title replacing the pending one, the cwd resolving against the session workspace across all four of its cases, the panel resetting the card's expand state when the selection changes, the chat row's expand-gated body against the panel's full-height one, `BashRow`'s resident card and its agreement with its own summary row's state dot, and the panel's Output section including the run_code sub-dispatch and the out-of-window head. That file is written against no gate pressure — `packages/client/ui-conversation/src/*` sits on the coverage `exclude` list in `vitest.config.ts`, so a coverage run over this package measures none of these files.
+
+`apps/web/tests/terminal-card.snapshot.ts` pins the assembled application over the built client bundles: the same render intent at both conversation render sites and in both chat-row shapes, because a bash call reaches a resident card only through the keyed `BashRow` registration and every other terminal-declaring tool name lands on the render-site fallback row, whose body is expand-gated. Fixture turn 65 was named `bash` and turn 60 left as `fx-bash` so one fixture covers both shapes, and turn 60's command was made two lines so the built-bundle snapshot pins the per-line prompt and its single dot (`dotsPerPromptRow: [1, 0]`). That terminal turn is ordered BEFORE the todo turn on purpose: the standing plan retires at the next `turn/start`, so appending it after would have emptied the dock's plan strip and taken the todo surfaces' own coverage with it; that turn also carries what turn 60's two prompt rows cannot — SGR runs resolved to `--dsw-*` tokens, output past the chat cap, a nested cwd, and a non-zero exit authored beside the sample. The sample's body deliberately carries NO `[exit code: N]` line: the real bash presenter consumes that marker out of the body precisely because the card shows the exit as its own pill, so leaving it in would pin a frame showing the exit twice — one the product path cannot produce.
+
+`apps/web/tests/navigation-panes.e2e.ts` adds the real-browser scenario over its existing `echo NAVIGATION_OK` bash call, asserting what jsdom cannot compute: squeezing the output pane below its content width leaves the line at one row and gives the pane horizontal overflow, the run-state dot resolves to the green success token rather than to a literal color (a `--dsw-*` var has no computed value at all without the real theme stylesheet) and sits inside the card box yet left of the prompt label, which is the invariant the gutter padding owns, and the copy control reaches the page's own async Clipboard API rather than the `execCommand` fallback. Its `terminal-card.expected.md` golden records the resolved workspace in the prompt row, which is what a bash call with no `workdir` must show instead of a bare `$`.

+# Agent Note: Web terminal card — the bash render intent reaches the browser
+
+Status: implemented
+
+[English](2026-07-28-web-terminal-card.md) | 中文
+
+## Problem
+
+bash 工具的调用与结果都声明 `card: 'terminal'`（[渲染意图联合类型](../architecture/2026-07-02-tool-render-intent-union.md)）：调用视图携带命令、一段可选的模型撰写描述以及工作目录，结果视图携带输出、退出码与终止信号。该视图早已抵达浏览器——host、connection 与 runtime 把它投递到 `ConversationSnapshot` 的 `callView`/`resultView` 上——TUI 也早已把它渲染为带 `$` 提示符的卡片，附退出行与首尾高度上限。
+
+Web client 却对它视而不见。`packages/client/ui-conversation/src/client/contract/tool-call-model.ts` 仅从原始工具参数推导每一行，`skeleton/DetailsPanel.tsx` 则把所有工具的内容块压平进一个 `
`，样式为 `white-space: pre-wrap; word-break: break-word`。软换行加上没有高度约束，带来两个缺陷：多列输出（`ls`、表格、制表符绘图）被折成一段文字，丢掉了这类输出赖以存在的列对齐；而单列的长列表会把详情面板拉长到与列表等长。
+
+## Decision
+
+`TerminalBlock` 是 `ui-primitives` 中把 shell 命令渲染为终端表面的组件，bash 调用在 Web 侧的两个渲染点都经由它消费 terminal 渲染意图：聊天工具行展开后的正文，以及详情面板的 Output 区。`ui-conversation/src/client/contract/terminal-card-model.ts` 是把快照上的 `callView`/`resultView` 这一对转换为该组件 props 的唯一位置，因此两个渲染点不可能在命令、cwd 或退出状态上产生分歧。当两侧都不声明 `card: 'terminal'` 时它返回 null，即走 generic 路径——包括本 client 版本不认识的 `card` 取值；当一个已落定调用的结果视图是 generic 时同样返回 null，这正是 bash 工具的执行错误与后台启动得以保持既有渲染的方式。渲染意图契约交给 UI 桥接层的两项职责也落在这里，而不在工具侧：已落定结果的 `title` **替换**待定标题；工作目录针对会话 workspace 解析——视图给出的绝对路径原样使用，相对路径在 workspace 之下拼接，省略则**就是** workspace，而这正是不带 `workdir` 的 bash 调用的常见情形。纯 presenter 看不到会话 cwd，因此该解析属于这道接缝；两个渲染点各自从会话列表行取出 cwd 传入。只有**存在**的调用视图才能表示「省略了 cwd，因此取 workspace」：当分页窗口丢掉调用头时，任何地方都不再有 cwd——结果视图并不携带它——而原调用完全可能使用过一个显式 workdir，因此提示行绘制一个裸 `$`，而不是命名一个它无法知晓的目录。解析后的路径还会归一化其 `.`／`..` 段，因为 bash 执行器在运行前就已解析 workdir：相对 `/w/app` 的 `..` 实际运行在 `/w`，因此提示标签必须读作 `w` 而不是 `..`。UNC 路径的 `server` 与 `share` 属于其根，而非可弹出的路径段，因为 Windows 无法越过一个共享向上。调用视图的 `description` 走同一处推导，因为契约把它渲染在卡片上方，且它必须优先于该行由参数推导出的摘要。三个渲染点都会绘制它：两种聊天行形态与详情面板。展开后的行自行绘制它，因为一行处于展开态时其折叠摘要是隐藏的——否则该描述将只在折叠时可见，这与「位于卡片上方」的含义正好相反。
+
+该组件的契约：
+
+- **提示符行，每条命令行一行。** 命令的每一行各占一行：标签，其后原样跟随该行。因此一个在两行上承载两条 shell 命令的 `command` 就读作它本身的两条命令，而不是被压成一行并省略号截断。标签取 cwd 的最后一段路径，当 cwd 等于 `home` prop 时取 `~`——浏览器没有 `$HOME`，因此由调用方提供绝对家目录，不提供时该折叠不生效。视图不带 cwd 时渲染一个纯 `$`。末尾换行是终止符，不是一条空的末命令。只有**第一行**携带该标签：视图只知道一个工作目录——调用开始处的那个——而后面的行完全可能在别处运行，命令里一个 `cd` 就足以改变它。把标签在各行重复，等于陈述一个此处无人知晓的逐行目录，这与运行状态点只出现一次是同一个理由。其余行保留一个裸 `$`，因此它们仍读作提示符。
+- **整次调用一枚运行状态点，位于第一行。** 它是 `StateDot` 四种状态中的三种：运行期间为追逐动画，与渲染状态徽章相同的退出状态为红色，干净落定为绿色——与工具行行首图标使用同一个指示器，因此一行与其自身的卡片不可能对同一条命令产生分歧。该状态点存在的理由是：读者对一条 shell 命令的第一个问题就是它是否仍在运行；没有它时，这一点只能从「没有输出」推断，而一条落定后无输出的命令看起来也一样。它以脱离文档流的方式落在卡片以**自身左内边距**预留的落区里，因此既不会缩进其命令，也不依赖命令自身的文本度量来与之对齐。该预留用 padding 而非 margin，是因为每个渲染点都会整条重写 `margin` 来设定自己的缩进——那会静默取消基于 margin 的落区，并让容器把状态点裁掉。无论有多少行，都只有一枚：视图携带的退出状态属于整次调用，而 bash 不报告逐条命令的状态，因此每行一枚状态点就等于在断言——一条在失败调用中其实成功了的命令行自身失败了。那一处视觉隐藏的文本标签具有相同的作用域，因为 `StateDot` 是 `aria-hidden`，而每行一个标签会被辅助技术读成好几个各自独立的结果。
+- **不软换行。** 输出行使用 `white-space: pre`，置于横向滚动的容器内。列对齐得以保留；长行滚动，而非折行。
+- **高度上限与展开控件。** 输出超过 `DEFAULT_TERMINAL_MAX_LINES`（16）行时，显示 `ceil(max/2)` 行首部加余下的尾部行数，中间是一个按钮，报告被隐藏的行数并可展开。计数针对的是剥除输出末尾终止符之后解析出的行，因此以换行结尾的 N 行输出就是 N 行。切分算法与 TUI transcript 折叠态工具卡片（`packages/ui/tui/src/components/transcript.ts`）完全一致，因此同一条命令的首尾切片在两个前端之间吻合。
+- **ANSI 颜色。** `anser` 切分 SGR 分段；`ui-primitives/src/ansi.ts` 把每段解析为内联样式，渲染成 React span。只设前景色的分段把基本 16 色映射到 `--dsw-*` 主题 token，使作者指定的颜色在两种主题下都可读；自行绘制背景的分段则前后景都保留 anser 给出的字面 rgb，以保住它意图中的对比度，256 色板、truecolor 以及本设计系统没有对应 token 的两种基本色同样如此。不承载颜色的转义序列（OSC 串、非 CSI 转义、无显示意义的 C0 控制符）在解析前被剥除，因此绝不会以字面字符抵达 DOM。光标移动在该剥除之前先行结算，且落在逐行的列缓冲里而不是靠字符串手术，因为回车与退格**只移动**光标——两者都不擦除任何东西，所以读者看到的就是每一列最后被写入的内容。`100%` 后接回车再接 `OK` 显示为 `OK0%`，因为这次重绘比它下面的帧更短；末尾 `abc` 加一个退格仍显示 `abc`，因为没有任何东西覆盖过那个 `c`；`abc` 加两个退格再接 `XY` 显示 `aXY`。这些用例都对照真实终端核实过，因为先前「截断加删除」的近似看起来是对的，实际并不对。SGR 状态按列打戳，与终端按单元格存储颜色的方式一致，因此部分覆盖会保留每个存活字符自身的颜色：红色 `bad`、三个退格、再写 `ok`，显示为 `okd` 且那个 `d` 仍是红的。CSI 序列不占列，只改变后续写入被打上的状态——这也正是回车不会重置颜色的原因，以及 SGR 状态会从一行延续到下一行、而不是在每个换行处关闭的原因。行内擦除属于同一次重放，因为 `\r\x1b[K` 是每个 spinner 与进度条都会写的同一个惯用法——只建模 `\r` 会让上一帧的尾巴留在原处，那是终端从未显示过的文本。只有 `m` 会累加进单元格样式；光标或擦除序列不能累加，否则状态串会随每次重绘线性增长，并发出 anser 只能丢弃的边界。SGR 按单元格以**归一化记录**保存（前景、背景、属性集合），而不是序列历史：累积原始序列会让每个状态边界重新发射整条链，因此不做完整 reset 的换色输出会发射 O(n^2) 个字符——3200 个这样的单元格产生 25 MB 并最终 `RangeError`，远低于 bash 自身的输出上限。该记录也让所有 chalk 系工具写出的属性闭合码（`39`、`49`、`22`、`24` 等）真正闭合其属性，且每个边界只为它开启的状态发射一条规范序列。一个分段也必须**收束**：重放收敛到扫描结束时的状态，而不是最后一个被写入单元格的状态——因为最后一次写入之后的 reset 不改变任何单元格，却结束了该分段；没有这一步，以 `\x1b[0m` 结尾的行会把颜色泄漏到其后所有行。光标按终端列推进，因此制表符前进到下一个 8 列制表位、宽字符占两列（其续列在首列被覆盖后变为空白而非合拢），组合标记不占列。宽度依据 emoji **presentation** 而非 U+2600–U+27BF 整个区块：`\u2713`——每条进度行都会写的对勾——只占一列，把该区块整体当作双宽恰好会错位这张卡片赖以存在的那类输出。写入宽字符对的任一半都会把另一半清成空白，因为终端无法让一个双格字形只留下一格：`a\tb` 之后用 `XY` 重绘显示为 `XY      b`，因为两个字符的重绘到不了第 8 列。
+- **退出状态与复制。** 非零退出码或信号渲染一枚状态徽章，与 bash 工具自身渲染器所作的退出状态区分一致；干净退出不渲染徽章，落定后的空输出渲染一处变暗的占位文字——该判定读的是卡片实际渲染的解析行，而非原始文本，因为只含转义或控制字节的输出能通过 `trim()` 却解析不出任何可见内容，否则就会画出一片空行外加一个把不可见字节写进剪贴板的复制控件。复制控件复制的是原始输出文本而非渲染后的树，因此提示符行与徽章不会进入剪贴板。
+
+几何尺寸、圆角与字体沿用 `CodeBlock`，因此终端卡片与围栏代码块在视觉上一致；`white-space: pre` 加横向滚动是有意的分歧。两个组件都需要的剪贴板写入从 `CodeBlock` 中提取到包内部的 `src/clipboard.ts`，不对外导出，因此它仍是这两个块的实现细节。
+
+### 聊天行内嵌输出推翻了一条既有约定
+
+`chat/ToolRow.tsx` 与 `contract/tool-call-model.ts` 都断言过「绝不内嵌输出——完整结果在详情面板」。在行内显示终端块推翻了这一点，依据是 owner 的明确决定。
+
+这次推翻成立的理由：对 shell 命令而言，输出**就是**用户要读的结果，把它专门收进面板会让最常见的情形变成两步交互。行内一个有界、限高、不换行的终端块，正是让 bash 密集的 transcript 一遍读完的条件。旧规则真正担心的是行高不受输出长度约束，而高度上限加展开控件正是防止其复现的机制。
+
+余下的约束：行内上限为 `CHAT_TERMINAL_MAX_LINES`（8），是组件默认值的一半，而面板沿用默认值——消息流是跨多次调用阅读的摘要表面，面板才是单次调用的阅读表面。只有 terminal 意图内嵌渲染；generic 工具的内容依旧只在面板中。
+
+这一划分的一个前提此后被削弱了：[工具行已不再是详情面板的点击目标](2026-07-28-tool-call-file-open-in-os.md)，且没有任何手势接替它，因此该面板在组装后的应用中当前不可达。于是行内上限成为读者实际拥有的唯一长输出表面，由展开控件承担。恢复面板入口属于那次改动的后续，而非本次改动——但在它落地之前，「面板仍是查看完整输出的地方」并不成立，行内的展开控件独自承担了这一职责。
+
+## Alternatives considered
+
+**只在详情面板渲染终端块。** 这样保留既有的「不内嵌输出」约定，也不需要记录任何推翻。已被 owner 的明确决定否决：shell 命令的输出正是用户来读的东西，把它挪到一次点击之外，代价高于该约定带来的收益。此处记录的是 owner 的裁决，而非从代码库推导出的结论。
+
+**复用 `CodeBlock` 并传入 `console` 语言，而不新建组件。** 已否决：`CodeBlock` 会软换行，而软换行正是本次要修的缺陷，且它没有退出状态、没有 cwd 提示符行、没有高度上限、也不处理 ANSI。把四项终端专属关注点加进共享的代码围栏组件，等于把它们强加给每一个 markdown 围栏。两个组件改为共享几何与字体 token，那是唯一一处「一套实现对两者都正确」的部分。
+
+**手写 SGR 解析器。** 已否决：SGR 解析器恰是[优先采用维护良好的依赖而非手写](../process/2026-07-26-dependencies-over-hand-rolling.md)所指明不该自持的那类实现——它的边界情形（256 色板与 truecolor 形式、`reverse`、多参数分段、未终止的序列）各自只在没人会写进测试的输出上失效，因此手写版本会在很长时间内一直微妙地出错。对照那条策略的门槛如实陈述：`anser` **并未**删除任何既有自持代码。它是一次能力增补，而那条 Agent Note 把这与净删除式的简化区分开来；它清过的是健康度与边界契合这两半门槛。`anser` 未覆盖而仍由我们手写的部分是：主题 token 的颜色映射、非 CSI 序列的剥除、回车重绘，以及供高度上限切片的逐行 span 折叠。
+
+## Consequences
+
+`anser` 成为 `packages/client/ui-primitives` 的一项新运行时依赖，因此该包的每个消费方都为它支付一次。Web 聊天中的 bash 行现在承载输出，相比只有摘要的行，这是有意提高的信息密度；上限是维持其有界的机制，而调紧上限是改一个 prop，不是重新设计。
+
+`TerminalBlock` 只读取 terminal 视图携带的字段，因此它始终是渲染意图内容的纯函数——不查会话状态，与产出该视图的 presenter 一样可安全回放。不具备终端能力的 UI 仍从桥接层拿到围栏式回退；工具的结果形态未作任何改动。
+
+在当前已交付的 wire 上，`run_code` 子派发不会得到终端卡片：`session.ts` 把 `tool/code-dispatch(-start)` 折叠为 `callView: null`／`resultView: null`，而 host 的 `viewFor` 只呈现顶层的 `tool/call`／`tool/result`，因此嵌套的 bash 调用保持通用的压平形式。两条分支都已钉住——注入视图后的解析路径，以及 wire 实际投递的无视图形态——因此这个缺口是被记录下来的，而非暗含的。把 presenter 视图贯穿 code-dispatch wire 属于那道接缝自身的改动。
+
+内嵌渲染的许可仅授予 terminal 意图。将来想要内嵌的意图需要有自己的边界与自己的决定，且需针对此处记录的理由来论证，而不是仅针对「只在面板」这条约定本身。

+`packages/client/ui-primitives/tests/ansi.spec.ts` 固定解析层：基本色的 token 映射、无对应 token 取值的字面 rgb、带背景分段的前后景配对、每一项装饰以及其中两项之间的 `textDecoration` 冲突、OSC 串与非 CSI 转义及无显示意义控制符的剥除、光标重放（较短重绘让上一帧尾巴留存、末尾退格不擦除任何东西、行内擦除的全部三种参数形式、制表位、宽字符、SGR 跨行延续，以及光标／擦除序列绝不进入单元格样式），以及 CRLF 的保留。每一条重放用例都先对照真实终端核实过。`packages/client/ui-primitives/tests/terminal-block.spec.tsx` 固定组件：cwd 缩短、运行中／空／已落定三条分支、信号优先于退出码、末尾终止符规则、首尾高度上限及其 `aria-expanded` 开关、运行状态点全部三种可达状态及其位于提示符标签之前的位置、每条命令行一行的提示区及其位于第一行的单枚状态点，以及复制控件在剪贴板接受与拒绝两条路径上都断言原始输出，另有对 `writeClipboard` 的直接固定。
+
+`packages/client/ui-conversation/tests/terminal-card.spec.tsx` 固定每个渲染点上的接线：`terminalCardModel` 的推导及其每一处 null 分支、结果标题替换待定标题、cwd 针对会话 workspace 解析的全部四种情形、切换选中调用时面板重置卡片展开态、对话行受展开控制的输出体与面板的全高输出体的对比、`BashRow` 的常驻卡片及其与自身摘要行状态点的一致性，以及面板 Output 区段（含 run_code 子派发与超出窗口的调用头）。该文件在没有门禁压力的情况下写成——`packages/client/ui-conversation/src/*` 位于 `vitest.config.ts` 的覆盖率 `exclude` 列表中，因此覆盖率运行不会统计其中任何文件。
+
+`apps/web/tests/terminal-card.snapshot.ts` 在构建后的客户端产物上固定组装完整的应用：同一渲染意图在两个对话渲染点、以及两种对话行形态下的表现——因为 bash 调用只有经由带键的 `BashRow` 注册才得到常驻卡片，而其他任何声明 terminal 的工具名都落到渲染点兜底行上，其输出体受展开控制。fixture 第 65 轮改名为 `bash`、第 60 轮保留 `fx-bash`，于是一份 fixture 覆盖两种形态，并把第 60 轮的命令改为两行，使构建产物快照钉住逐行提示区及其单枚状态点（`dotsPerPromptRow: [1, 0]`）。该终端轮有意排在 todo 轮**之前**：站立计划会在下一次 `turn/start` 时退役，若追加在其后就会让 dock 的计划条变空，并连带毁掉 todo 表面自身的覆盖；该轮还承载第 60 轮两个提示行无法覆盖的部分——解析到 `--dsw-*` token 的 SGR 分段、超出对话上限的输出、嵌套 cwd，以及在样本旁另行标注的非零退出码。样本正文有意**不含** `[exit code: N]` 行：真实的 bash presenter 正是因为卡片以徽章单独呈现退出状态，才把该标记从正文中消费掉；若保留它，钉住的将是一帧把退出状态显示两次的画面——而产品路径产不出这一帧。
+
+`apps/web/tests/navigation-panes.e2e.ts` 在其既有的 `echo NAVIGATION_OK` bash 调用上新增真实浏览器场景，断言 jsdom 无法计算的部分：把输出面板挤压到窄于内容宽度后，行仍保持单行且面板产生横向溢出；运行状态点解析为绿色的 success token，而不是字面颜色（没有真实主题样式表时，`--dsw-*` 变量根本不产生计算值），且它位于卡片盒之内、提示标签之左——这正是那道 gutter 内边距所拥有的不变量；复制控件走的是页面自身的异步 Clipboard API，而非 `execCommand` 兜底路径。其 `terminal-card.expected.md` 基准记录了提示行中已解析的 workspace——这正是不带 `workdir` 的 bash 调用应当显示的内容，而非一个裸 `$`。

+# Agent Note: Address pending queue occurrences for edit and removal
+
+Status: implemented
+
+English | [中文](2026-07-29-addressable-queue-operations.zh.md)
+
+## Problem
+
+The Web queue rendered pending messages but could not edit or delete one row. `MessageId` was insufficient as an address because callers may enqueue the same immutable message more than once. The browser also inferred queue retirement from turn and status events, so a row operation racing with driver claim had no authoritative outcome.
+
+## Decision
+
+**Each accepted FIFO occurrence has its own identity.** AgentLoop mints an opaque `InboxItemId` and publishes an `InboxItem` containing that id, the identified `UserMessage`, and its acceptance-time `queued | steering` placement. Reusing one `MessageId` creates distinct inbox identities. Injection bypasses the FIFOs and receives no inbox identity.
+
+**Mutation ends at driver claim.** `Agent.updateInbox(id, action)` synchronously searches the pending queued FIFO. Edit replaces frozen content while preserving `InboxItemId`, `MessageId`, source, wake policy, and position. Remove emits the occurrence’s terminal discard. Steering and driver-claimed occurrences return `not-found`, so queue operations never rewrite active-turn input or durable history.
+
+**The live ledger is authoritative.** `agent/inbox/enqueue`, `update`, `dequeue`, and `discard` maintain a Host mirror of queued occurrences. A synchronously re-entrant update or terminal event may reach the mirror before its outer enqueue listener; the mirror retains that unseen outcome for the current dispatch and folds it into the enqueue, so listener registration order cannot publish stale content or a ghost row. The wire sends complete `session/queue` snapshots rather than incremental guesses. Reconnect sends the current baseline, and every queued mutation or terminal event replaces it. The client applies no optimistic edit and never retires a row from durable turn events or status changes.
+
+**Queue addresses require a live Agent.** `session.updateQueue` queries only the mounted Agent registry and never resumes a cold session: an `InboxItemId` is process-local and cannot name work after restart or disposal. A missing Agent and a driver-claimed occurrence both return `queue-item-not-found`.
+
+**Web actions address Queue only.** The Host excludes pending steering from `session/queue`; steering retains its existing durable transcript path after consumption. QueueDock exposes edit and delete, but no send-now control. The UI derives queue row and mutation types from the runtime `SessionFace` contract rather than importing the connection plugin, so plugin cooperation continues through services and snapshots. Edit is available only when all content blocks are text; the editor cannot silently drop non-text blocks. An editing row exposes only save and cancel, with Enter and Escape as their keyboard equivalents. Delete removes the exact occurrence.
+
+## Alternatives considered
+
+**Address rows by `MessageId`.** Rejected because one immutable message may be sent repeatedly; editing or deleting by message identity would affect an ambiguous occurrence.
+
+**Apply optimistic browser mutations.** Rejected because driver claim and another client can win before the Host action. Waiting for the authoritative snapshot makes the ownership boundary visible and lets `queue-item-not-found` report a real race.
+
+**Include pending steering in the queue mutation protocol.** Rejected because QueueDock has no steering interaction, and editing or deleting active-turn input would widen this feature beyond its current consumer. A dedicated steering interaction owns that delivery contract.
+
+**Expose a protocol-only promotion operation.** Rejected because no product interaction reorders Queue. A public operation without a current consumer would add ordering semantics and tests for speculative use.
+
+**Resume a cold Agent for a queue operation.** Rejected because durable session identity does not preserve the process-local inbox capability. Resuming can only produce `not-found` after creating unrelated live state.
+
+## Verification
+
+AgentLoop contract tests hold prompt admission while editing and removing exact queued occurrences, reject mutations of steering occurrences, and verify the resulting independent turn and terminal lifecycle events. Host schema and proxy tests cover queued-only authoritative snapshots, synchronous re-entrant mutation order, reconnect, cold-Agent rejection, typed not-found errors, and the RPC transport. Client runtime and QueueDock tests cover non-optimistic projection, text-only editing, save and cancel affordances, removal, retirement races, and disabled mixed-content editing. Keyless browser scenarios drive the exposed edit and delete actions through the built Web composition and real HTTP/SSE wire.
+
+## Consequences
+
+Queued work gains precise row operations without becoming durable session history. Occurrence identity is a live process-local capability and disappears at claim, cancellation, disposal, or restart; reconnect recovers only queued items still held by the live Agent. Editing excludes mixed content until an editor can preserve every block, while pending steering remains outside this operation surface.
+
+The protocol now carries full queue snapshots on each change. Queues are expected to remain short, so deterministic recovery and multi-client convergence are preferred over an incremental mutation protocol.

+# Agent Note（agent 决策记录）：为待处理队列项提供编辑与移除操作
+
+Status: implemented
+
+[English](2026-07-29-addressable-queue-operations.md) | 中文
+
+## 问题
+
+Web 队列能够渲染待处理消息，但无法编辑或删除其中某一行。`MessageId` 不足以充当寻址标识，因为调用方可以多次将同一条不可变消息加入队列。浏览器还会根据轮次和状态事件推断队列项已退役，因此当行操作与驱动器认领发生竞态时，系统无法给出权威结果。
+
+## 决策
+
+**每次获准进入 FIFO 的项都有独立标识。** AgentLoop 会铸造不透明的 `InboxItemId`，并发布一个 `InboxItem`，其中包含该 id、已有标识的 `UserMessage`，以及接受时确定的 `queued | steering` 放置方式。复用同一个 `MessageId` 会创建不同的 inbox 标识。注入绕过 FIFO，因此不会获得 inbox 标识。
+
+**变更边界止于驱动器认领。** `Agent.updateInbox(id, action)` 会同步搜索待处理的 queued FIFO。编辑会替换已冻结的内容，同时保留 `InboxItemId`、`MessageId`、来源、唤醒策略和位置。移除会发出该次入队项的终态 discard。steering（中途引导）项和已被驱动器认领的项会返回 `not-found`，因此队列操作绝不会改写活动轮次输入或持久历史。
+
+**实时账本是权威状态。** `agent/inbox/enqueue`、`update`、`dequeue` 和 `discard` 共同维护 queued 入队项的 Host 镜像。同步可重入的 update 或终态事件可能先于外层 enqueue 监听器到达镜像；镜像会在当前分发期间保留这一尚不可见的结果，并在处理 enqueue 时把它合并进去，因此监听器注册顺序不会导致系统发布陈旧内容或不存在的行。协议发送完整的 `session/queue` 快照，而非增量猜测。重连会发送当前基线，每次 queued 变更或终态事件都会整体替换它。客户端不会进行乐观编辑，也绝不根据持久轮次事件或状态变化退役队列行。
+
+**Queue 寻址要求 Agent 存活。** `session.updateQueue` 只查询已挂载的 Agent 注册表，绝不恢复冷会话：`InboxItemId` 属于进程本地标识，无法在重启或资源释放后继续指向工作。Agent 缺失和单次入队项已被驱动器认领这两种情况都返回 `queue-item-not-found`。
+
+**Web 操作只面向 Queue。** Host 从 `session/queue` 中排除待处理 steering；steering 消费后仍沿用既有的持久 transcript（文本记录）路径。QueueDock 暴露编辑和删除，不提供立即发送控件。UI 从运行时 `SessionFace` 契约派生队列行与变更类型，而不是导入连接插件，因此插件仍通过服务和快照协作。仅当所有内容块都是文本时才提供编辑功能；编辑器不能静默丢弃非文本块。编辑中的行只展示保存和取消操作，对应的键盘操作分别是 Enter 和 Escape。删除会移除对应的精确入队项。
+
+## 考虑过的替代方案
+
+**通过 `MessageId` 寻址行。** 不予采纳，因为同一条不可变消息可以重复发送；按消息标识编辑或删除会无法确定应操作哪一次入队。
+
+**在浏览器中进行乐观变更。** 不予采纳，因为驱动器认领或另一个客户端可能先于 Host 操作完成。等待权威快照可以显式呈现所有权边界，并让 `queue-item-not-found` 报告真实竞态。
+
+**将待处理 steering 纳入队列变更协议。** 不予采纳，因为 QueueDock 没有 steering 交互，而编辑或删除活动轮次输入会把此功能扩展到当前消费方之外。应由专用 steering 交互负责该投递契约。
+
+**暴露仅协议层的前移操作。** 不予采纳，因为当前没有产品交互会重新排序 Queue。公开一个没有当前消费方的操作，会为了推测性用途引入排序语义和测试。
+
+**为队列操作恢复冷 Agent。** 不予采纳，因为持久会话标识不会保留进程本地的 inbox 寻址凭据。恢复只能在创建无关的实时状态后得到 `not-found`。
+
+## 验证
+
+AgentLoop 契约测试会在编辑和移除精确 queued 入队项时阻塞提示词接纳，拒绝对 steering 入队项的变更，并验证所得独立轮次及终态生命周期事件。Host schema 与代理测试覆盖仅含 queued 项的权威快照、同步可重入变更顺序、重连、拒绝冷 Agent、类型化 not-found 错误和 RPC 传输。客户端运行时和 QueueDock 测试覆盖非乐观投影、仅文本编辑、保存与取消入口、移除、退役竞态，以及禁用混合内容编辑。无密钥浏览器场景会通过构建后的 Web 组合和真实 HTTP／SSE 协议操作公开的编辑和删除。
+
+## 后果
+
+queued 工作获得精确的行操作，但不会因此成为持久会话历史。单次入队标识是进程本地的实时寻址凭据，会在认领、取消、dispose 或重启时消失；重连只能恢复仍由活跃 Agent 持有的 queued 项。编辑会排除混合内容，直至编辑器能够保留每个块；待处理 steering 则不属于此操作接口。
+
+现在，协议会在每次变更时携带完整队列快照。队列预期保持较短，因此系统优先选择确定性恢复和多客户端收敛，而非增量变更协议。

+# Agent Note: Ask-question Web presentation
+
+Status: implemented
+
+English | [中文](2026-07-29-ask-question-web-presentation.zh.md)
+
+## Problem
+
+The Web GUI could already collect answers through the `QuestionComposer` composer takeover, but the transcript around it was wrong on three counts. A pending question rendered twice: once as the composer takeover and once as the read-only `PendingCard` placeholder that predates the takeover. A settled `ask_user_question` call rendered as the generic "Tool call" row dumping raw args JSON, so the two composer verdicts — the user dismissing the whole set (`ASK_CANCELLED`) and a turn interrupt landing while the question was pending (`ASK_ABORTED`) — both read as anonymous red-dot failures. And the composer's own chrome copy (pager, buttons, placeholders, validation feedback) was hardcoded Chinese while the surrounding client is bilingual through `dsh-client-locale`.
+
+Separately, the composer visuals had drifted from the current design: an expand-to-open custom answer entry, no multi-select affordance beyond a trailing check, header-mounted paging, and a `（可多选）` title-suffix convention parsed out of model text.
+
+## Decision
+
+A pending question owns exactly two surfaces: the composer takeover collects the answers, and a dedicated `ask_user_question` toolview row in the transcript names the interaction outcome. The row registers into the keyed `conversation.chat.toolview` hole exactly like `todo_write` and composes the shared `ToolRow` (chrome, running sweep, leading expansion). Its summary is the interaction verdict rather than args: `waiting` while running, `N/M answered` from the result JSON once settled (a skipped answer — empty `selected`, no `custom` — stays out of the count), `cancelled` for `ASK_CANCELLED`, and `interrupted` with the shared amber stopped semantics for `ASK_ABORTED`. Malformed or truncated results fall back to the generic summary. `PendingCard` narrows to `PendingWait<'approval'>` and `ChatView` filters the pending list to approval waits, so the placeholder card now exists only for the approval takeover still on the roadmap.
+
+The composer redesign moves paging into the footer next to the actions, renders multi-select options with explicit checkboxes, keeps single-select numbered rows, and replaces the expand-to-open custom entry with an always-visible custom input row (textarea for optionless questions). The `parseQuestionTitle` multi-select suffix convention is deleted; `multi_select` is already structured metadata, so the title renders verbatim.
+
+Composer chrome copy becomes bilingual: the plugin registers zh/en dictionaries under the `question` namespace of `dsh-client-locale` and hands the entry a namespace-bound translator plus the locale snapshot as a hooks-compartment source through the slot inject face, so a locale flip re-renders a mounted composer. Validation feedback is stored as a dictionary key and re-translated on flip; carrier failure messages and all model-authored question/option text render verbatim.
+
+Two adjacent fixes ride along. All generic toolview leading icons (and the hover chevron) now inherit the single tertiary label color — the others-variant secondary override and the separate chevron color rule are deleted, leaving only the intentional cordis business-primary accent. And the client dev-watch bundler registers each CSS module with `addWatchFile`, because the virtual-module indirection previously hid css-only edits from the watcher.
+
+## Alternatives considered
+
+**Keep rendering questions through `PendingCard`.** Rejected: the card was a read-only placeholder from before the takeover existed, so a pending question showed the same content twice with one copy not answerable. The toolview row plus takeover covers both the transcript record and the collection surface.
+
+**Show the questions or answers inline in the transcript row.** Rejected: the composer takeover owns question rendering and answer collection, and the row convention (`todo_write`) is one line with details in the panel. The row therefore reports only the outcome, mirroring how the todo row reports counts while the panel owns the list.
+
+**Render `ASK_CANCELLED`/`ASK_ABORTED` through the generic error shape.** Rejected: dismissal is the user's own deliberate action and an interrupt is the shared stop gesture; both are expected outcomes, not tool failures. Naming the verdict (and keeping amber stopped semantics for the abort) matches how interrupted tool calls read elsewhere.
+
+**Translate the row verdicts now.** Deferred by explicit product decision: the row's `waiting`/`answered`/`cancelled`/`interrupted` strings stay English for this change; the composer chrome i18n landed because its Chinese-only copy was already wrong for the en locale.
+
+**Keep the title-suffix multi-select convention.** Rejected: `multi_select` is structured request metadata and the checkbox affordance now carries the signal, so parsing `（可多选）` out of model text was a fragile duplicate channel.
+
+## Consequences
+
+`ask_user_question` and `todo_write` now demonstrate the intended toolview pattern: compose `ToolRow`, summarize from call args or result JSON with shape-checked fallbacks, and register through the keyed slot. The bespoke `todo-row.module.css` is gone.
+
+The row verdict strings are the one remaining hardcoded-English surface of the question flow; localizing them is deferred follow-up. `PendingCard` remains a visible-but-not-answerable approval placeholder until the approval composer takeover ships.
+
+`ui-question` gains a `dsh-client-locale` dependency and an inject face where it previously had none; its contract (`QuestionComposerInjected`) lives with the consumer in `contract/slots.ts`.
+
+## Verification
+
+`ui-conversation` tests pin the row's waiting/answered/skipped/cancelled/interrupted/fallback matrix, the approval-only pending filter, and the slot registration; `ui-question` tests pin the redesigned composer (checkbox multi-select, always-visible custom row, footer pager, dictionary-key feedback re-translation, IME-safe Enter) and the plugin's dictionary registration plus inject face; `ui-primitives` tests pin the icon set. The assembled Web GUI was exercised against a live session covering answer, cancel, and turn-interrupt paths.

+# Agent Note：Ask-question Web 呈现
+
+Status: implemented
+
+[English](2026-07-29-ask-question-web-presentation.md) | 中文
+
+## 问题
+
+Web GUI 已经可以通过 `QuestionComposer` 的输入区接管收集回答，但其周边的会话记录呈现在三个方面是错的。待回答的问题会渲染两次：一次是输入区接管，一次是早于接管存在的只读 `PendingCard` 占位卡片。已结算的 `ask_user_question` 调用渲染为通用 "Tool call" 行并直接倾倒原始 args JSON，因此两种输入区裁决 —— 用户放弃整组问题（`ASK_CANCELLED`）与问题待回答期间轮次被打断（`ASK_ABORTED`）—— 都显示为无名的红点失败。而且输入区自身的界面文案（分页、按钮、占位符、校验反馈）是硬编码中文，而周边客户端已通过 `dsh-client-locale` 实现双语。
+
+另外，输入区视觉也偏离了当前设计：自定义回答需展开才能输入、多选除尾部对勾外没有可见标识、分页挂在头部、还有从模型文本里解析 `（可多选）` 标题后缀的约定。
+
+## 决定
+
+一个待回答的问题恰好拥有两个界面：输入区接管收集回答，会话记录中一个专门的 `ask_user_question` toolview 行陈述交互结果。该行与 `todo_write` 完全一样注册进带 key 的 `conversation.chat.toolview` 槽位，并复用共享的 `ToolRow`（外观、运行扫光、前导展开）。其摘要是交互裁决而非参数：运行中显示 `waiting`，结算后从结果 JSON 得出 `N/M answered`（被跳过的回答 —— `selected` 为空且无 `custom` —— 不计入），`ASK_CANCELLED` 显示 `cancelled`，`ASK_ABORTED` 显示 `interrupted` 并沿用共享的琥珀色 stopped 语义。畸形或截断的结果回退到通用摘要。`PendingCard` 收窄为 `PendingWait<'approval'>`，`ChatView` 将待处理列表过滤为仅审批等待，占位卡片从此只服务于仍在路线图上的审批接管。
+
+输入区重设计将分页移到底部操作区旁，多选选项渲染显式复选框，单选保留编号行，并用始终可见的自定义输入行取代展开式自定义入口（无选项问题用多行文本框）。删除 `parseQuestionTitle` 的多选后缀约定；`multi_select` 已是结构化元数据，标题原样渲染。
+
+输入区界面文案实现双语：插件在 `dsh-client-locale` 的 `question` 命名空间下注册中英词典，并通过槽位 inject face 向条目提供绑定命名空间的翻译器和作为 hooks 舱源的 locale 快照，语言切换时已挂载的输入区会重新渲染。校验反馈以词典 key 存储、切换时重新翻译；载体失败消息与所有模型撰写的问题/选项文本原样渲染。
+
+两个相邻修复随行。所有通用 toolview 前导图标（含悬停箭头）现在统一继承三级标签色 —— 删除了 others 变体的二级色覆盖和独立的箭头颜色规则，只保留有意为之的 cordis 业务主色强调。客户端 dev-watch 打包器用 `addWatchFile` 注册每个 CSS 模块，因为虚拟模块间接层此前使仅改 CSS 的编辑对 watcher 不可见。
+
+## 曾考虑的替代方案
+
+**继续通过 `PendingCard` 渲染问题。** 否决：该卡片是接管存在之前的只读占位，导致同一内容显示两份且其中一份不可作答。toolview 行加接管同时覆盖了记录与收集两个面。
+
+**在会话记录行内联显示问题或回答。** 否决：输入区接管拥有问题渲染与回答收集，而行的约定（`todo_write`）是单行、详情在面板。因此行只报告结果，正如 todo 行报告计数而面板拥有列表。
+
+**用通用错误形态渲染 `ASK_CANCELLED`/`ASK_ABORTED`。** 否决：放弃是用户自己的主动操作，打断是共享的停止手势；两者都是预期结果而非工具失败。命名裁决（且中止保持琥珀色 stopped 语义）与其他被打断的工具调用的呈现一致。
+
+**现在就翻译行内裁决文案。** 依明确的产品决定推迟：本次改动中行的 `waiting`/`answered`/`cancelled`/`interrupted` 字符串保持英文；输入区界面文案的国际化落地是因为其仅中文的文案在 en 语言下本就是错的。
+
+**保留标题后缀的多选约定。** 否决：`multi_select` 是结构化请求元数据且复选框标识已承载该信号，从模型文本解析 `（可多选）` 是脆弱的重复通道。
+
+## 后果
+
+`ask_user_question` 与 `todo_write` 现在共同示范预期的 toolview 模式：复用 `ToolRow`、从调用参数或结果 JSON 做带形状校验回退的摘要、通过带 key 的槽位注册。专用的 `todo-row.module.css` 已删除。
+
+行内裁决字符串是问题流程仅剩的硬编码英文面；将其本地化是推迟的后续工作。在审批输入区接管交付之前，`PendingCard` 仍是可见但不可操作的审批占位。
+
+`ui-question` 新增 `dsh-client-locale` 依赖和此前没有的 inject face；其契约（`QuestionComposerInjected`）与消费者一起放在 `contract/slots.ts`。
+
+## 验证

+# Agent Note: Persistent Bash and string-replacement editor tools
+
+Status: implemented
+
+English | [中文](2026-07-29-persistent-bash-str-replace-editor.zh.md)
+
+## Problem
+
+Some deployments need a one-call Bash schema whose shell state survives across model turns, while others need a Claude-style `str_replace_editor` independent of their terminal choice. Bundling the two tools or naming them after one benchmark would prevent reuse and blur configuration ownership.
+
+## Decision
+
+`@deepseek-ai/dsh-tool-bash-persistent` consumes `ctx.pty` and registers one `bash(command)` tool. It lazily creates one interactive shell per exact Agent and serializes that owner's calls. Cwd, exported variables, activated environments, functions, and background jobs persist. Random private markers delimit command output. Retained scrollback is paged backward to recover the command's original prefix; a dropped prefix is reported explicitly. A nonzero wrapped command appends `[exit code: N]`; a shell that dies before reporting that status instead appends `[shell exited: code N]`, `[shell killed by signal: SIG]`, or `[shell exited]` when the backend supplies neither. `maxOutputChars` bounds retained command output, while fixed diagnostics can extend the returned string. Timeout or cancellation closes the shell before another call can reuse uncertain state, and model-visible timeout/exit results disclose that reset. Cancellation always resets and discards the result, even when a complete status marker is already observable, so state changes the model never saw cannot survive. The configurable description defaults to persistence facts only, so network and package-mirror claims remain deployment-owned.
+
+`@deepseek-ai/dsh-tool-str-replace-editor` independently consumes `ctx.fs` and registers `str_replace_editor` with `view`, `create`, `str_replace`, and `insert`. It provides numbered text views, filtered two-level directory listings, unique literal replacement, canonical insertion boundaries, and bounded output. Paths are absolute; file views preserve content tabs so copied text remains valid literal replacement input; mutations preserve tabs outside the requested edit; and the public schema and failures use only `old_str`. The plugin can compose with persistent Bash, one-shot Bash, sandboxed Bash, or no shell.
+
+`dsh-system-prompt` accepts `includeHarnessIdentity: false`, while `dsh-agent-spine-demo` forwards that setting and accepts `toolBash: false`. A deployment can therefore own an exact persona and replace the spine's native Bash without duplicate prompt or tool registrations. Existing defaults remain unchanged.
+
+Both plugins are included in the Python runtime closure. The persistent Bash closure also includes the PTY service/local backend and the sandbox services required by that backend. Because `node-pty` executes a native `spawn-helper` on macOS, each packaged macOS runtime executable ships with a `-spawn-helper` sibling; Linux uses `forkpty` directly. A pinned `node-pty` patch checks `DSH_NODE_PTY_SPAWN_HELPER` first, so it remains a true override for a current external consumer that supplies a non-sibling helper. When the override is unset, the patch resolves the packaged executable sibling if present and otherwise preserves upstream lookup in ordinary Node runs. The macOS builders fail before publication when the helper is absent or not executable.
+
+## Alternatives considered
+
+**One combined compatibility plugin.** Rejected because neither tool requires the other and the combined name would tie reusable capabilities to one benchmark.
+
+**Reuse one-shot Bash.** Rejected because `bash -c` cannot preserve cwd or environment state across calls.
+
+**Expose terminal management tools.** Rejected because open/send/read/close is a different model action space from one persistent `bash` call.
+
+**Modify native read/write/edit.** Rejected because it would distort their general-purpose contracts instead of adding an independently composable editor.
+
+## Consequences
+
+Profiles can reproduce an external agent by configuring persona and descriptions while the underlying packages remain general. Persistent Bash requires an owning Agent and real PTY backend. Shell exit, timeout, or cancellation loses state. The editor delegates security and mutation policy to the mounted filesystem stack. Runtime-wheel consumers still need no Node installation; Linux wheels contain one executable, while macOS wheels also contain its private native helper.

+# Agent Note：持久 Bash 与字符串替换编辑器工具
+
+状态：已实现
+
+[English](2026-07-29-persistent-bash-str-replace-editor.md) | 中文
+
+## 问题
+
+部分部署需要只调用一次的 Bash schema，同时要求 shell 状态跨模型轮次保留；另一些部署需要与终端选择无关的 Claude 风格 `str_replace_editor`。把两个工具绑在一起或按某个基准命名，会阻碍复用并模糊配置归属。
+
+## 决策
+
+`@deepseek-ai/dsh-tool-bash-persistent` 消费 `ctx.pty` 并注册一个 `bash(command)` 工具。它为每个精确 Agent 惰性创建一个交互式 shell，并串行化该所有者的调用。Cwd、导出的变量、已激活环境、函数和后台任务会保留。随机私有标记划分命令输出；保留的 scrollback 会向前分页，以恢复命令真正的输出前缀，若前缀已被丢弃则明确告知。经封装的命令以非零状态结束时，会追加 `[exit code: N]`；若 shell 在报告该状态前终止，则改为追加 `[shell exited: code N]`、`[shell killed by signal: SIG]`，或在后端既未提供退出码也未提供信号时追加 `[shell exited]`。`maxOutputChars` 限制保留的命令输出，而固定诊断可能使返回字符串更长。超时或取消会先关闭 shell，避免下一次调用复用状态不确定的会话，模型可见的超时／退出结果也会说明该重置。取消始终会重置 shell 并丢弃结果，即使已经能观察到完整状态标记也是如此，从而不会让模型未曾看到的状态变更得以保留。可配置描述默认只声明持久性事实，因此网络和软件包镜像等声明仍归部署所有。
+
+`@deepseek-ai/dsh-tool-str-replace-editor` 独立消费 `ctx.fs`，注册包含 `view`、`create`、`str_replace` 与 `insert` 的 `str_replace_editor`。它提供带行号文本查看、过滤后的两层目录列表、唯一字面量替换、规范插入边界和有界输出。路径必须为绝对路径；文件查看会保留内容中的制表符，因此复制的文本仍可作为有效的字面量替换输入；变更会保留请求编辑范围之外的制表符；公开 schema 与错误则只使用 `old_str`。它可以与持久 Bash、一次性 Bash、沙箱 Bash 或无 shell 组合。
+
+`dsh-system-prompt` 接受 `includeHarnessIdentity: false`；`dsh-agent-spine-demo` 会转发该设置，并接受 `toolBash: false`。因此部署可以拥有精确 persona，并替换 spine 的原生 Bash，而不会重复注册提示词或工具。既有默认值不变。
+
+两个插件都进入 Python runtime 闭包。持久 Bash 的闭包还包含 PTY 服务／本地后端，以及该后端要求的沙箱服务。由于 `node-pty` 在 macOS 上会执行原生 `spawn-helper`，每个打包后的 macOS 运行时可执行文件都会携带一个 `-spawn-helper` 伴随文件；Linux 直接使用 `forkpty`。固定版本的 `node-pty` 补丁会先检查 `DSH_NODE_PTY_SPAWN_HELPER`，因此对当前提供非伴随 helper 的外部消费方而言，该变量仍是真正的覆盖项。未设置该覆盖时，补丁会在打包可执行文件的伴随文件存在时解析它，否则在普通 Node 运行中保留上游查找方式。若 helper 缺失或不可执行，macOS 构建器会在发布前失败。
+
+## 考虑过的替代方案
+
+**单一组合兼容插件。** 被拒绝，因为两个工具互不依赖，组合命名还会把可复用能力绑定到某个基准。
+
+**复用一次性 Bash。** 被拒绝，因为 `bash -c` 无法跨调用保留 cwd 或环境状态。
+
+**暴露终端管理工具。** 被拒绝，因为 open/send/read/close 与单个持久 `bash` 调用是不同的模型动作空间。
+
+**修改原生 read/write/edit。** 被拒绝，因为这会扭曲其通用契约，而不是增加一个可独立组合的编辑器。
+
+## 后果
+
+Profile 可以通过配置 persona 和描述复现外部 Agent，而底层包保持通用。持久 Bash 需要拥有它的 Agent 与真实 PTY 后端；shell 退出、超时或取消会丢失状态。编辑器把安全与变更策略委托给挂载的文件系统栈。运行时 wheel 包的消费方仍无需安装 Node；Linux wheel 包包含一个可执行文件，macOS wheel 包还包含其私有原生 helper。

+# Agent Note: Web message IconActions and clocks
+
+Status: implemented
+
+English | [中文](2026-07-29-web-message-icon-actions-and-clock.zh.md)
+
+## Problem
+
+The web chat user bubble already had copy / branch / edit IconActions but no clock. Finalized assistant narration had no under-body action chrome at all, even though the Harness design shows a copy / branch / clock row after the answer settles. Streaming replies must not flash that chrome mid-token. Memoized rows also keep stable props across midnight, so a one-shot `Date.now()` would leave yesterday's messages stuck on `HH:mm`.
+
+## Decision
+
+**User bubbles prepend a date-aware local clock to the existing IconActions row; finalized assistant *content* nodes (non-empty text blocks) append a copy / branch / clock row with `margin-top: 16px`; both seats stay visible whenever mounted and re-format at the next local midnight.**
+
+Both seats format `node.time` through `formatMessageClock`: same calendar day → `HH:mm`, earlier this year → `M月D日 HH:mm`, other years → `YYYY年M月D日 HH:mm`. `useCalendarDay` is a component-local day tick (timeout to the next local midnight) so memoized rows re-render when the calendar day changes without a new framework hook. `MessageItem` places the label before copy (figma `388:20051`). `AssistantMarkdown` places it after branch (figma `43:32997`) only when `streaming` is false, the event time is known, and the node has non-empty text content; Think-only nodes and the streaming tail omit the row. Copy writes joined text blocks. Branch stays a chrome stub. Clipboard write and the clock helpers live in `message-chrome.ts`. The assembled surface is pinned by `apps/web/tests/message-actions.e2e.ts` (cold-seeded history + aria golden); aria normalization collapses every clock shape to `{{clock}}`.
+
+## Alternatives considered
+
+**Show assistant IconActions during streaming.** Rejected: the request is to reveal the row only after output completes; mid-stream chrome would flicker and invite copying a partial answer.
+
+**Put IconActions under every finalized assistant node (including Think-only).** Rejected: copy has nothing useful to write without text content, and repeating the chrome under every step/Think row clutters the flow; only content output owns the seat.
+
+**Hover-reveal the action row on hover-capable pointers.** Rejected: once the row exists it should stay discoverable; opacity hiding made the chrome easy to miss and required parent hover selectors that duplicated the mount gate.
+
+**Wire branch to a real session fork.** Rejected for this change: same rationale as the archived [user IconActions note](../../archived/feature/2026-07-27-user-message-icon-actions.md) — the mutation path is unspecified; the button reserves the design seat.
+
+**Publish the calendar day through a chat store or inject hook.** Rejected: the day tick is presentation-only local state with no cross-entry consumers; a component-local timeout matches the client rule that behavioral hooks may own state that does not subscribe to an external source.
+
+## Consequences
+
+Settled assistant content answers expose copy and the event clock as soon as the row mounts; Think-only nodes stay chrome-free; branch stays a stub. User and assistant clocks share the same day/year widening rules and refresh after midnight without a message mutation. Per-message paging remains a deferred footer seat in the package README. Package tests pin the three clock shapes, the midnight widen, and the content-only assistant gate; the web e2e scenario pins the assembled IconActions chrome.

+# Agent Note: Web 消息 IconActions 与时钟
+
+Status: implemented
+
+[English](2026-07-29-web-message-icon-actions-and-clock.md) | 中文
+
+## 问题
+
+Web 聊天的用户气泡已有复制／分支／编辑 IconActions，但没有时钟。已定稿的 assistant 叙述下方完全没有操作栏，尽管 Harness 设计稿在回答结束后展示复制／分支／时钟。流式回复不得在 token 中途闪出该栏。经 memo 的行在跨午夜时仍保持稳定 props，因此一次性的 `Date.now()` 会让昨日消息一直卡在 `HH:mm`。
+
+## 决策
+
+**用户气泡在既有 IconActions 行前追加感知日期的本地时钟；已定稿的 assistant *内容*节点（非空 text 块）在正文下追加带 `margin-top: 16px` 的复制／分支／时钟；两边只要挂载就保持可见，并在下一个本地午夜重新格式化。**
+
+两边都通过 `formatMessageClock` 格式化 `node.time`：同一日历日 → `HH:mm`，同年更早 → `M月D日 HH:mm`，跨年 → `YYYY年M月D日 HH:mm`。`useCalendarDay` 是组件本地的日刻度（定时到下一个本地午夜），因此 memo 行在日历日变化时会重渲染，且不新增框架 hook。`MessageItem` 把标签放在复制之前（figma `388:20051`）。`AssistantMarkdown` 把它放在分支之后（figma `43:32997`），且仅在 `streaming` 为 false、已知事件时间、且节点含非空 text 内容时渲染；纯 Think 节点与流式尾部省略该行。复制写入拼接后的 text 块。分支仍是 chrome stub。剪贴板写入与时钟辅助函数放在 `message-chrome.ts`。组装面由 `apps/web/tests/message-actions.e2e.ts`（冷 seed 历史 + aria golden）钉住；aria 归一化把每种时钟形态折叠为 `{{clock}}`。
+
+## 曾考虑的方案
+
+**在流式过程中展示 assistant IconActions。** 否决：需求是输出完成后才展示该行；中途 chrome 会闪烁，并诱使复制半截回答。
+
+**给每个已定稿 assistant 节点（含纯 Think）都挂 IconActions。** 否决：没有 text 内容时复制没有可写内容，且在每一步／Think 下重复 chrome 会打乱流程；只有内容输出拥有该座位。
+
+**在具备 hover 能力的指针上用 hover 才揭示操作行。** 否决：行一旦存在就应保持可发现；用 opacity 隐藏容易漏看，且需要父级 hover 选择器重复挂载门控。
+
+**把分支接到真实的会话 fork。** 本次否决：与已归档的[用户 IconActions 笔记](../../archived/feature/2026-07-27-user-message-icon-actions.md)同一理由——变更路径尚未规定；按钮只预留设计座位。
+
+**通过 chat store 或 inject hook 发布日历日。** 否决：日刻度只是展示层本地状态，没有跨入口消费者；组件本地 timeout 符合「行为 hook 可拥有不订阅外部源的状态」这一客户端规则。
+
+## 后果
+
+已定稿的 assistant 内容回答在行挂载后立刻暴露复制与事件时钟；纯 Think 节点不带 chrome；分支仍为 stub。用户与 assistant 时钟共用同一套跨天／跨年加宽规则，并在午夜后无需消息变更即可刷新。逐消息分页仍是包 README 中的暂缓 footer 座位。包级测试钉住三种时钟形态、午夜加宽与 assistant 仅内容门控；Web e2e 场景钉住组装后的 IconActions chrome。

+# Agent Note: Web composer stats detail and input-zone polish
+
+Status: implemented
+
+English | [中文](2026-07-30-web-composer-stats-and-input-polish.zh.md)
+
+## Problem
+
+The web composer footer showed a single joined stats string (cache/tokens/turns/steps) in its own stack row, visually detached from the input card and missing the design's duration and token-split details. The input zone itself had accumulated per-entry spacing hacks: dock strips carried their own margins, the sticky seat sat on a solid fill that clipped the transcript hard, the back-to-bottom control cleared the composer by a hardcoded offset that broke as the draft grew, and the goal and todo strips disagreed on surface color and column width.
+
+## Decision
+
+**The stats line renders inside the InputBar's width column through a new `footer` owner prop and expands to the design's grouped detail row; the composer stack owns one 6px rhythm; the seat fades the transcript through a fixed 36px token-bound gradient; the back-to-bottom control follows a live `--dsh-composer-height`; goal, todo, and queue share one 752px tip-fill column.**
+
+- `'conversation.composer.dock'` entries reach the page as the `ComposerBarOwnerProps.footer` slot, rendered under the card inside the bar's `.root`, so the stats line and the card share one width constraint. `StatsLine` derives everything client-side from the snapshot: turns/steps, LLM wall time from assistant `timing` (`completedTime - stepStartTime`), tool wall time from tool-result `time - callTime` pairs, prompt/output token split with cache-read folded into input, and cache-hit percentage. Groups render pipe-separated and drop out whole when empty; `formatTokens` (517 / 12.2K / 1.2M) and `formatDuration` (45.2s / 2m42s) are exported for tests. Durations cover only in-window nodes — the README owns that limitation.
+- `.composerStack` carries the Figma composition matrix's 6px gap. Goal and Todo remain standalone cards; the terminal Queue entry subtracts that gap plus the named 5px layout overlap so the later composer card paints over only the queue edge. The [composer context stack decision](../bug-fix/2026-07-30-composer-context-stack-order.md) owns the order and overlap contract.
+- The sticky seat's background is a `linear-gradient` from `color-mix(bg-base 0%, transparent)` at 0px to solid `bg-base` at 36px — pixel stops, not the figma export's percentage, so a growing draft widens only the solid region; `color-mix` keeps both themes fading from their own base.
+- A `useCallback` ref on the seat attaches a ResizeObserver that publishes `--dsh-composer-height` on the scroll body; ChatView's back-to-bottom slot computes `bottom` from it (152px first-paint fallback) instead of the prior hardcoded 168px.
+- The textarea's 52px two-line floor applies to the hero variant only; the docked composer collapses to content height. Goal, Todo, and Queue panels use the 44px-gutter / 752px-cap column with `tip` fill and l1 border; the standalone Goal and collapsed Todo cards are 36px and 44px tall.
+
+## Alternatives considered
+
+**Percentage gradient stops (the figma export's 24%).** Rejected: the stop scales with seat height, so a tall draft stretches the fade band over most of the transcript; the fixed 36px band equals the design's 24% at the resting ~150px composer and stays constant as the composer grows.
+
+**A generic "bottommost entry tucks" contract.** Rejected because Goal and Todo are independent cards even when either is the last visible dock entry. Queue owns the one intentional composer overlap, while the stack owns its shared gap and overlap values.
+
+**Backend-supplied duration fields for the stats line.** Unnecessary: assistant `timing` and tool call/result pairs already reach the snapshot, so wall times fold client-side with no new session event or host projection.
+
+**Keeping the stats line as a composer-stack sibling.** Rejected: as a stack row it carried its own width constraint that drifted from the card's; as the bar's `footer` both share one column and the stats participate in the seat's sticky/gradient region by construction.
+
+## Consequences
+
+The stats row reads turns/steps, LLM and tool durations, cache hit, and input/output tokens at a glance, at the cost that durations cover only the loaded event window (README Known Limitation). The stack's fixed order keeps standalone context cards independent and makes Queue the only panel joined to the composer; a future dock entry must choose its order relative to those roles. The fade band is a constant 36px, so any future design retune is one stop value. `chat-stats-bash-sample.spec.tsx` pins the derivation (timing/tool folds, token split), both formatters, the grouped render, and the zero-renders-during-streaming acceptance.

+
+## Problem
+
+Web 编辑器页脚原本以独立 stack 行显示一条拼接的统计字符串（cache／tokens／turns／steps），视觉上与输入卡脱节，且缺少设计稿中的耗时与 token 拆分细节。输入区自身也积累了逐条目的间距补丁：dock 条各带自己的 margin，sticky 座位下是硬切消息流的纯色填充，「回到底部」控件用硬编码偏移躲避编辑器、草稿一长高就失效，goal 与 todo 条的底色和列宽也互不一致。
+
+## Decision
+

+
+## Alternatives considered
+
+**百分比渐变节点（figma 导出的 24%）。** 否决：节点随座位高度缩放，长草稿会把过渡带拉伸到消息流的大半；固定 36px 过渡带等于设计稿在静息 ~150px 编辑器下的 24%，且随编辑器长高保持恒定。
+
+**通用「最底条目贴卡」契约。** 不予采纳，因为 Goal 和 Todo 即使成为最后一个可见 dock 条目，也仍是独立卡片。Queue 拥有唯一一处有意的 composer 重叠，而 stack 拥有共享的间距和重叠量。
+
+**由后端为统计行提供耗时字段。** 不必要：assistant `timing` 与工具 call/result 配对已经到达快照，墙钟时间可在客户端折算，无需新的会话事件或 host 投影。
+
+**统计行保持为 composer stack 的兄弟节点。** 否决：作为 stack 行它携带独立的宽度约束、与卡片漂移；作为 bar 的 `footer`，两者共享一列，统计行也天然落在座位的 sticky／渐变区域内。
+
+## Consequences
+
+统计行现在一眼可读 turns／steps、LLM 与工具耗时、缓存命中和输入／输出 token，代价是耗时只覆盖已加载事件窗口（README 已知限制）。stack 的固定顺序使独立的上下文卡片彼此分离，并让 Queue 成为唯一与 composer 相接的面板；未来新增 dock 条目时，必须选择自己相对于这些角色的顺序。过渡带恒为 36px，未来设计调整只改一个节点值。`chat-stats-bash-sample.spec.tsx` 钉住推导（timing／工具折算、token 拆分）、两个格式化器、分组渲染，以及流式期间零重渲染的验收。

+# Agent Note: Web context injection disclosure
+
+Status: implemented
+
+English | [中文](2026-07-30-web-context-injection-disclosure.zh.md)
+
+## Problem
+
+The Web conversation rendered every logged non-user message through the generic `JsonBlock`. That presentation used a textual triangle, compact label typography, a bordered JSON panel, and unrelated spacing, so context injection did not match the Tool calls disclosure shown in the product design. Restyling the generic primitive would also change unknown events and attachment fallbacks.
+
+## Decision
+
+`MessageItem` routes context nodes to `ContextInjectionRow`. The row starts collapsed, names the presentation `上下文注入`, uses the existing browse glyph, and exposes the whole 24px header as one pointer and keyboard disclosure target. Its expanded body begins 4px below the header at the shared 22px content indent and renders the design's 141px scrollport with 8px radius, code-block background, 11/16 code text, and no border.
+
+`ContextInjectionRow` serializes both logged `content` and `source` into one inline JSON value, preserving provenance alongside model-visible material. The display remains bounded by the existing 20,000-character truncation policy. It changes no session event, runtime fold, or context-producing plugin.
+
+The package-internal `DisclosureRow` owns the header geometry, icon-to-chevron transition, controlled open state, and Enter/Space behavior shared by context and `ToolRow`. `ToolRow` remains the semantic owner of tool state, summaries, file links, and expanded tool bodies. Context does not enter the keyed toolview slot and gains no context-specific slot while all context sources share one presentation.
+
+## Verification
+
+Conversation component tests pin the collapsed default, browse glyph, whole-row pointer and keyboard toggles, inline JSON shape, truncation, and unchanged generic unknown-event rendering. The keyless assembled-Web history scenario injects context through the real Agent API, records the collapsed row in its ARIA golden, and measures the design's icon, header, indent, gap, scrollport, padding, radius, typography, color, and overflow in Chromium.
+
+## Alternatives considered
+
+**Restyle `JsonBlock` globally.** Unknown surface events and miscellaneous content blocks use that primitive for a separate generic fallback, so a global visual change would couple unrelated presentations.
+
+**Render context as a read tool.** Reusing `ToolRow` directly would add false tool semantics, state and keyed dispatch to a logged non-user message.
+
+**Add a keyed context-view slot.** Every current context source uses the same title and provenance body. A registration seam has no present consumer and can be added without changing the row if distinct source-owned presentations emerge.
+
+## Consequences
+
+Context injection matches the Tool calls visual language without changing its durable meaning. The shared disclosure header prevents the two rows from drifting, while the dedicated context body and generic `JsonBlock` remain independently evolvable. The fixed-height body trades automatic expansion for a stable transcript rhythm and requires scrolling to inspect long injected instructions.

+# Agent Note: Web 上下文注入展开项
+
+Status: implemented
+
+[English](2026-07-30-web-context-injection-disclosure.md) | 中文
+
+## 问题
+
+Web 会话原本通过通用 `JsonBlock` 渲染每条已记录的非用户消息。这种呈现使用文本三角符号、紧凑的标签字体、有边框的 JSON 面板和另一套间距，因此上下文注入与产品设计中的 Tool calls 展开项不一致。修改通用原语的样式还会影响未知事件和附件的兜底呈现。
+
+## 决策
+
+`MessageItem` 将上下文节点路由至 `ContextInjectionRow`。该行初始折叠，标题为 `上下文注入`，使用现有的浏览图标，并使整个 24px 标题栏成为可通过指针和键盘操作的展开目标。其展开主体从标题栏下方 4px 处开始，与共用的 22px 内容缩进对齐，并渲染设计规定的 141px 滚动区；滚动区采用 8px 圆角、代码块背景、11/16 代码文本且无边框。
+
+`ContextInjectionRow` 将已记录的 `content` 和 `source` 序列化为一个内联 JSON 值，在模型可见内容旁保留来源信息。显示内容继续受现有的 20,000 字符截断策略约束。该变更不修改任何会话事件、运行时折叠逻辑或上下文生成插件。
+
+包内部的 `DisclosureRow` 负责上下文行和 `ToolRow` 共用的标题栏几何、图标至折叠箭头的过渡、受控打开状态，以及 Enter／Space 操作。`ToolRow` 仍是工具状态、摘要、文件链接和展开后工具主体的语义 owner。所有上下文来源共用同一套呈现；上下文不会进入键控 toolview slot，也不会获得上下文专用 slot。
+
+## 验证
+
+会话组件测试固定验证初始折叠状态、浏览图标、整行的指针与键盘切换、内联 JSON 形状、截断，以及通用未知事件渲染保持不变。无密钥的组装后 Web 历史场景通过真实 Agent API 注入上下文，在 ARIA 预期输出中记录折叠行，并在 Chromium 中测量设计规定的图标、标题栏、缩进、间隙、滚动区、内边距、圆角、字体排版、颜色和溢出行为。
+
+## 考虑过的替代方案
+
+**全局重新设置 `JsonBlock` 样式。** 之所以否决：未知 surface 事件和其他内容块使用该原语作为独立的通用兜底呈现，全局视觉变更会把无关的呈现耦合起来。
+
+**将上下文渲染为 read 工具。** 之所以否决：直接复用 `ToolRow` 会为已记录的非用户消息添加错误的工具语义、状态和键控分发。
+
+**新增键控 context-view slot。** 之所以否决：当前所有上下文来源都使用相同的标题和来源信息主体，注册 seam 暂无消费方。如果将来出现由不同来源拥有的呈现，仍可在不更改该行的情况下添加此 seam。
+
+## 后果
+
+上下文注入与 Tool calls 采用一致的视觉语言，同时不改变其持久保存的语义。共用的展开项标题栏可以防止这两种行逐渐偏离，而专用的上下文主体与通用 `JsonBlock` 仍可独立演进。固定高度的主体以无法随内容自动增高为代价，为 transcript（文本记录）维持稳定的排版节奏；查看较长的注入指令时必须滚动。

 The repo shipped on **Yarn 4** with the `node-modules` linker — a deliberately conservative choice that behaves like npm's flat layout while giving us Yarn's workspaces and `yarn constraints`. It worked. But Yarn 4's Plug'n'Play heritage makes the `node-modules` linker the off-the-beaten-path mode, and the broader JS ecosystem — tooling defaults, CI actions, Corepack examples, contributor familiarity — increasingly centers on pnpm. For a repo that is built primarily by agents and read by occasional human contributors, "the package manager most tools and people expect" has real value: fewer surprises, better-trodden failure paths, more copy-pasteable answers.
 
-The switching cost is at its lowest right now. Nothing publishes from this repo yet (every package is `private: true`); dev/test/demo all run **unbuilt** via tsx, so the package manager only has to (a) resolve and link `node_modules`, (b) run the workspace scripts, and (c) enforce the workspace constraints. The one Yarn-specific asset is `yarn.config.cjs` (the `@yarnpkg/types` constraints engine), which is small and mechanical to re-express. This mirrors the reasoning in [the tsdown decision](../../archived/process/2026-06-11-tsdown-over-dumble.md): swap a load-bearing tool for the healthier-ecosystem option while the blast radius is still small.

 本仓库最初使用 **Yarn 4** 搭配 `node-modules` 链接器启动。这是一个刻意保守的选择：行为类似 npm 的扁平布局，同时享有 Yarn 的 workspaces 和 `yarn constraints`。它能正常工作。但 Yarn 4 源自 Plug'n'Play 的血统，使得 `node-modules` 链接器成为非主流模式；而更广泛的 JS 生态——工具默认值、CI action、Corepack 示例、贡献者的熟悉度——正日益以 pnpm 为中心。对于一个主要由 agent（智能体）构建、偶尔有人类贡献者阅读的仓库而言，「大多数工具和人所期望的包管理器」具有实际价值：更少的意外、更成熟的故障路径、更多可直接复用的解答。

 Context and agent-dispatch calls contribute only finite string-literal event sets. Direct `EventsService.dispatch()` calls recover the event slot through array literals, constant aliases, conditional branches, and resolved call sites of non-exported local helpers. Generic forwarding parameters are not concrete producers: attribution stays with the call sites that supply a closed event value.
 
+Semantic queries run only where a branch can consume them: calls are prefiltered by the closed event-API method-name set before receiver classification, and helper call sites are indexed on demand instead of eagerly resolving every call in every package source. The demand-driven index proves locality per helper — a helper that is non-exported, sits in a real ES module, and whose every same-file reference is a direct callee has all of its calls in that file by module scoping, so only that file is indexed. Any unproven premise (an export modifier, a global script file, an aliasing or otherwise unclassifiable reference) falls back to the original full package-source index, which is the unchanged original semantics; the proof affects cost, never results. A lazy single global index was rejected because the helper-parameter path is reached on the current tree, so it would still pay nearly the whole `getResolvedSignature` sweep.
+
 Every declared harness event must have a discovered producer. A missing producer fails generation as dead vocabulary or an unsupported semantic dispatch shape; listener-free extension points remain valid. `internal/dispatch` instrumentation is not treated as a subscription to every event it observes, so the matrix contains direct product listeners rather than manually asserted indirect relationships.

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.

 - 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.
+- Each distinct confirmed snapshot retains a content-addressed local ref and object. An abandoned re-record may therefore leave an extra durable pin, but it changes no branch or commit history; this local retention is the tradeoff that prevents garbage collection from invalidating an accepted pairing record.
 - `--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.

 - **Dependency**: `shiki/core` + `@shikijs/langs`, composed via `createHighlighterCoreSync` with `createJavaScriptRegexEngine({ forgiving: true })` — no oniguruma WASM, no async init, bundle-friendly. Grammar allowlist: `typescript` (embeds JS), `shellscript`, `json` — the languages the harness actually renders; everything else falls back to a geometry-identical plain block, never an error. Prior art: the VitePress site already renders all documentation code through shiki, and TextMate grammars materially beat regex highlighters on TypeScript — the payload that matters here.
 - **Singleton**: `ui-primitives/src/markdown/highlight.ts` creates one `HighlighterCore` per document and exposes `highlightToHtml(code, lang)` (undefined = render plain). Engine + grammar construction is a ~120-175ms long task, so the module pre-warms the singleton in a deferred task at plugin boot (the lazy path stays as the correctness fallback), keeping the cost off the render path where a stream's finalize swap would jank. The alias table is a `Map`, not an object: fence info strings are assistant-authored, so a label like `constructor` must miss instead of resolving an inherited property and crashing shiki. The shared `CodeBlock` component owns both arms; its shiki arm injects the generated span tree via `dangerouslySetInnerHTML` — sanctioned because shiki emits a static span tree computed from the code text (no user HTML passes through, no scripts/handlers), shiki's own documented consumption path.
 - **Theming**: shiki's `createCssVariablesTheme` routes every token color through `--shiki-*` custom properties; the VALUES live in a new `ui-theme/styles/shiki.css` token sheet (light on `:root`, dark on `body[data-ds-dark-theme]` — the same cascade as every other sheet), imported by the shell's `base.css` chain. Component CSS stays tokens-only; no literal color ever enters JS or component sheets. Background/foreground alias the existing markdown code-block tokens so highlighted and plain blocks agree.
-- **Surfaces**: markdown fences (`MarkdownText`'s `pre` component routes single-string fences through `CodeBlock`), the `run_code` expanded program body (ToolRow's code variant, `lang="typescript"`), and the details panel's Input args (`lang="json"`). Output stays plain deliberately — tool output is arbitrary text, and guessing a grammar would mis-highlight more than it helps.

+# Agent Note: Oxlint as the repository linter
+
+Status: implemented
+
+English | [中文](2026-07-29-oxlint-linter.zh.md)
+
+## Problem
+
+The repository needs type-aware TypeScript correctness rules, consistent formatting, and file-local duplicate-logic checks across its owned source. ESLint supplied those checks through a JavaScript parser, a project service, and multiple plugins, but a clean lint run spent about one minute on the local migration baseline and required an 8 GiB Node heap, CI result caches, and separately tuned ESLint concurrency.
+
+A faster runner cannot justify losing rules. The migration must preserve the strict type-checked preset, repository overrides, inline suppressions, @stylistic fixes, SonarJS checks, host/client TypeScript separation, and the vendor exclusion.
+
+## Decision
+
+The root [`.oxlintrc.json`](../../../../.oxlintrc.json) is the authoritative repository lint configuration. The `lint` package script, gate scheduler, CI, and lefthook invoke Oxlint through [`scripts/run-oxlint.ts`](../../../../scripts/run-oxlint.ts) for repository-wide, type-aware, or staged validation. The `lint:fix` script and lefthook first invoke the formatting-only [`eslint.format.config.mjs`](../../../../eslint.format.config.mjs), then run Oxlint. The direct `eslint` and `@typescript-eslint/parser` development dependencies exist only for this parser-without-project formatting pass; their exact versions pin the tested parser/fixer pairing, and that config contains no correctness or type-aware rules.
+
+`options.typeAware` enables `oxlint-tsgolint`. Its backend performs per-file TypeScript-project discovery: package sources use their package projects, host tests/examples/website use `tsconfig.host.json`, and client tests plus `scripts/client-bundle-purity.spec.ts` use `tsconfig.client.json`. The program-less root solution is never flattened. Oxlint's `--tsconfig` override affects import resolution but is ignored by type-aware linting, so this repository does not set it. The configuration explicitly carries the migrated strict-type-checked rules and repository overrides instead of enabling broad Oxlint categories whose contents may change. `typescript/no-unnecessary-condition` remains enabled from Oxlint's nursery set because it was an enforced repository rule before migration.
+
+Oxlint's JavaScript-plugin compatibility layer runs `@stylistic/eslint-plugin` and `eslint-plugin-sonarjs` so the existing formatting and file-local duplicate-logic rules remain enforced. The compatibility layer reports `@stylistic` violations but does not execute their fixers, so the formatting-only ESLint pass owns only the corresponding auto-fixes; an executable parity check keeps those fixable rule definitions aligned while `max-len` remains validation-only. Owned-source suppressions use `oxlint-*` directives and the `typescript/*` namespace, and unused directives remain warnings; vendored sources keep their upstream directives because Oxlint excludes `vendor/**`.
+
+CI does not restore or save a lint-result cache. `DSH_OXLINT_THREADS` makes the shared runner pass the same bound to Oxlint's `--threads` option and the type-aware backend's `GOMAXPROCS` environment variable; ordinary local runs use both defaults. Pre-commit applies the formatting-only ESLint fixes, runs Oxlint validation and native safe fixes, accepts selections containing only ignored files, and re-stages the result through lefthook.
+
+## Verification
+
+The migrated configuration reports the same clean owned-source baseline after resolving two analyzer differences: one redundant test assertion was removed, while one structural cast required by `tsc` carries a narrow Oxlint suppression. A one-time audit against the exact deleted ESLint configuration blob established source 88-to-88, examples 87-to-87, and tests 83-to-83 after the rule-name translations. The committed fingerprint pins those audited Oxlint profiles and the complete override shape; it neither executes the deleted configuration nor propagates later upstream preset changes. Evaluating `typescript-eslint@8.61.0` also confirms that `strictTypeChecked` did not enable `@typescript-eslint/no-empty-function`; the deleted tests-only `off` entry was inert.
+
+Executable contract tests require type-aware diagnostics from the package, host, and client projects; assert the client-only script's project; reject unmatched fallback analysis; and exercise the Stylistic, SonarJS, and nursery compatibility paths. They also pin unused-suppression reporting, ignored-only staged selections, formatter/validator rule parity, and final formatted bytes. Runner tests pin both worker controls, and typecheck confirms that migration-driven source edits preserve the TypeScript programs.
+
+## Alternatives considered
+
+**Run both linters repository-wide.** Every correctness rule is available through Oxlint's native rules, nursery rule, or JavaScript-plugin compatibility layer. A repository-wide ESLint fallback would preserve the slower project-service setup and two correctness configurations without adding a check; the retained ESLint pass is deliberately limited to project-free staged formatting.
+
+**Rely on compatibility-layer fixes.** The layer reports the established `@stylistic` rules but does not apply their fixes under either Oxlint fix mode. Keeping the narrow staged formatter preserves the contributor contract without broadening ESLint back into a repository linter.
+
+**Drop @stylistic or SonarJS rules that are not native.** This would remove dependencies but weaken the mechanical quality contract. The compatibility layer preserves those rules until native replacements can be evaluated as a separate decision.
+
+**Replace @stylistic with Oxfmt during the migration.** A formatter migration would change output beyond the lint-engine boundary and create a repository-wide formatting diff. Keeping the established rules makes this change reviewable and leaves formatter selection independent.
+
+## Consequences
+
+Local migration measurements reduced a clean type-aware lint run from about 61 seconds to about 8 seconds without a result cache. The exact ratio is host-dependent and is not a performance guarantee.
+
+Type-aware diagnostics now come from the TypeScript Go analyzer bundled through `oxlint-tsgolint`, so edge-case inference can differ from typescript-eslint even when `tsc` accepts the same program. Lint and typecheck remain separate required evidence.
+
+The JavaScript-plugin compatibility API and staged formatter are additional boundaries to maintain. Commits pay one project-free ESLint startup before Oxlint, and the root development graph retains ESLint plus the TypeScript parser. Repository-wide validation, type-aware analysis, cache policy, worker control, and inline directives remain Oxlint-owned.

+# Agent Note: 使用 Oxlint 作为仓库 linter
+
+Status: implemented
+
+[English](2026-07-29-oxlint-linter.md) | 中文
+
+## 问题
+
+仓库的自有源码需要类型感知的 TypeScript 正确性规则、一致的格式，以及文件内重复逻辑检查。ESLint 通过 JavaScript 解析器、项目服务和多个插件提供这些检查，但在本地迁移基线上，一次无问题的 lint 运行约需 1 分钟，并且需要 8 GiB Node 堆、CI 结果缓存和单独调优的 ESLint 并发度。
+
+不能以提高运行速度为由丢失规则。迁移必须保留严格类型检查预设、仓库覆盖配置、内联抑制指令、@stylistic 修复、SonarJS 检查、host/client TypeScript 隔离和 vendor 排除规则。
+
+## 决策
+
+根目录的 [`.oxlintrc.json`](../../../../.oxlintrc.json) 是仓库 lint 配置的权威来源。`lint` 包（package）脚本、门禁调度器、CI 和 lefthook 通过 [`scripts/run-oxlint.ts`](../../../../scripts/run-oxlint.ts) 调用 Oxlint，进行全仓库、类型感知或暂存验证。`lint:fix` 脚本和 lefthook 先调用仅用于格式化的 [`eslint.format.config.mjs`](../../../../eslint.format.config.mjs)，再运行 Oxlint。直接的 `eslint` 和 `@typescript-eslint/parser` 开发依赖仅用于这次不加载项目的格式化流程；其精确版本锁定经过测试的解析器与修复器配对，该配置不包含正确性规则或类型感知规则。
+
+`options.typeAware` 启用 `oxlint-tsgolint`。其后端按文件发现 TypeScript 项目：包源码使用各自的包项目，host 测试、示例和网站使用 `tsconfig.host.json`，client 测试及 `scripts/client-bundle-purity.spec.ts` 使用 `tsconfig.client.json`。不含程序的根解决方案绝不会被扁平化。Oxlint 的 `--tsconfig` 覆盖项会影响导入解析，但类型感知 lint 会忽略它，因此本仓库不设置该选项。该配置显式载入迁移后的严格类型检查规则和仓库覆盖配置，而不启用内容可能发生变化的 Oxlint 宽泛类别。`typescript/no-unnecessary-condition` 仍从 Oxlint 的 nursery 规则集中启用，因为它在迁移前就是仓库强制执行的规则。
+
+Oxlint 的 JavaScript 插件兼容层运行 `@stylistic/eslint-plugin` 和 `eslint-plugin-sonarjs`，从而继续强制执行现有的格式和文件内重复逻辑规则。兼容层会报告 `@stylistic` 违规，但不会执行其修复器，因此仅用于格式化的 ESLint 流程只负责相应的自动修复；一项可执行检查确保这些可修复规则定义保持一致，而 `max-len` 仅用于验证。自有源码中的抑制指令使用 `oxlint-*` 指令和 `typescript/*` 命名空间，未使用的指令仍作为警告报告；vendor 源码保留其上游指令，因为 Oxlint 会排除 `vendor/**`。
+
+CI 不恢复或保存 lint 结果缓存。`DSH_OXLINT_THREADS` 使共享运行器将同一上限传给 Oxlint 的 `--threads` 选项和类型感知后端的 `GOMAXPROCS` 环境变量；普通本地运行对两者均采用默认值。Pre-commit 应用仅用于格式化的 ESLint 修复，运行 Oxlint 验证和原生安全修复，接受仅含已忽略文件的文件选择，并通过 lefthook 重新暂存结果。
+
+## 验证
+
+解决两处分析器差异后，迁移后的配置报告与迁移前一致的自有源码无问题基线：移除了一项冗余测试断言，而 `tsc` 要求的一处结构性类型转换使用了窄范围的 Oxlint 抑制指令。以已删除 ESLint 配置的精确 blob 为基准进行的一次性审核在完成规则名映射后确认：源码为 88 项对 88 项，示例为 87 项对 87 项，测试为 83 项对 83 项。已提交的指纹锁定这些经审核的 Oxlint 规则配置及完整的覆盖结构；它既不执行已删除的配置，也不纳入后续的上游预设变更。对 `typescript-eslint@8.61.0` 的评估还确认，`strictTypeChecked` 并未启用 `@typescript-eslint/no-empty-function`；已删除、仅用于测试的 `off` 条目不起作用。
+
+可执行契约测试要求包、host 和 client 项目产生类型感知诊断，断言 client 专用脚本所用的项目，拒绝未匹配的回退分析，并检验 Stylistic、SonarJS 和 nursery 兼容路径。它们还锁定未使用抑制指令的报告行为、仅选择已忽略暂存文件的情况、格式化器与验证器之间的规则一致性，以及最终格式化后的字节。运行器测试锁定两项工作线程控制，类型检查则确认迁移引发的源码改动没有破坏 TypeScript 程序。
+
+## 考虑过的替代方案
+
+**在全仓库范围内同时运行两个 linter。** 所有正确性规则均可通过 Oxlint 原生规则、nursery 规则或 JavaScript 插件兼容层获得。在全仓库范围启用 ESLint 回退会保留较慢的项目服务初始化和两套正确性配置，却不会增加任何检查；保留的 ESLint 流程被刻意限制为不加载项目的暂存文件格式化。
+
+**依赖兼容层修复。** 兼容层会报告既有的 `@stylistic` 规则，但在 Oxlint 的两种修复模式下都不会应用这些规则的修复。保留窄范围的暂存文件格式化器，可以在不将 ESLint 扩张回仓库 linter 的情况下维持贡献者契约。
+
+**移除尚无原生实现的 @stylistic 或 SonarJS 规则。** 这会移除依赖，但也会削弱机械质量契约。兼容层会保留这些规则，直到能够通过单独决策评估原生替代规则。
+
+**迁移期间用 Oxfmt 替换 @stylistic。** 格式化器迁移会产生超出 lint 引擎边界的输出变化，并带来全仓库格式 diff。保留既有规则可使本次变更便于评审，并让格式化器选择保持独立。
+
+## 结果
+
+本地迁移测量显示，不使用结果缓存时，一次无问题的类型感知 lint 运行从约 61 秒缩短至约 8 秒。确切比例因主机而异，不构成性能保证。
+
+类型感知诊断现在来自通过 `oxlint-tsgolint` 捆绑的 TypeScript Go 分析器，因此即使 `tsc` 接受同一程序，边界场景下的类型推断也可能与 typescript-eslint 不同。lint 与类型检查仍是两项相互独立的必要证据。
+
+JavaScript 插件兼容 API 和暂存文件格式化器是需要维护的额外边界。每次提交在 Oxlint 之前需要启动一次不加载项目的 ESLint，根目录开发依赖图仍保留 ESLint 和 TypeScript 解析器。全仓库验证、类型感知分析、缓存政策、工作线程控制和内联指令仍由 Oxlint 负责。

-The TUI PTY smoke includes the Code Mode overlay composition, while `examples/cordis-agent/tests/keyless-smoke.e2e.ts` provides a minimal PTY boot over the real Cordis-agent Loader tree. The built `dsh` bin rejects a piped TUI launch before Loader boot and points at its one-shot `-p` mode; `apps/cli/tests/built-bin.e2e.ts` pins that path, while `cli-demo`'s built-bin suite runs text, JSON, and structurally parsed `stream-json` output under plain Node, persists fresh sessions, and rejects invalid arguments and missing config without contaminating stdout. Time-context integration uses the real Headless composition for two ordered turns, while its package tests own finer elapsed-time behavior.

+# Agent Note: Local JSON tree renderer
+
+Status: implemented
+
+English | [中文](2026-07-28-local-json-tree-renderer.zh.md)
+
+## Problem
+
+The read-only JSON inspector used by the [trajectory ledger](../feature/2026-07-27-trajectory-inspection-ledger.md) needs compact object and array previews, explicit array paths for copy actions, fixed-open and collapsible root modes, and keyboard navigation. `react-json-view-lite` exposes neither custom node rendering nor row identity, so satisfying those requirements through that dependency requires a package-manager patch against compiled distribution files and DOM traversal that reconstructs data paths from visible labels. The patch behaves as an untyped fork while its source maps and upstream source remain unchanged.
+
+## Decision
+
+`JsonTree` owns its recursive presentation in `dsh-client-ui-primitives`.
+
+- Each rendered row receives its value and property path directly. Object keys and array indexes extend that path during recursion, so copy actions never recover application data from rendered DOM text.
+- Expandable rows render the compact preview locally and mount child rows only while expanded. `expandTopLevel` selects between a fixed-open bracket frame and a collapsible root node without changing the public component contract.
+- The tree keeps one tabbable expander among visible nodes. Pointer activation claims that tab stop; Up and Down move it cyclically, while Left and Right collapse or expand the focused node.
+- `react-json-view-lite` is not a package dependency and has no pnpm patch. Focused component tests pin previews, expansion, keyboard focus, and array copy paths.
+
+## Alternatives considered
+
+**Keep the distribution patch.** Rejected because the application-specific renderer and array identity contract would remain hidden in generated third-party files, and every dependency update would require reviewing a fork without matching source maps.
+
+**Use the upstream renderer without previews.** Rejected because `{…}` and `[…]` discard the compact payload context that the trajectory inspector uses for scanning.
+
+**Inject previews and row metadata after render.** Rejected because effects or mutation observers would depend on the same private DOM structure while splitting one row between React ownership and imperative mutation.
+
+**Adopt a larger JSON viewer.** Rejected because editing, search, and theme systems are outside the current read-only contract; the added dependency surface would not remove the inspector-specific copy and layout code.
+
+## Consequences
+
+The JSON inspector has one source-level owner, explicit data flow, accurate array paths, and no patched dependency. The package now owns recursive rendering, expansion state, ARIA tree structure, and roving focus behavior, so changes to those semantics require focused component coverage. The implementation remains intentionally read-only and limited to the preview, navigation, and copy behavior used by current consumers.

+# Agent Note：本地 JSON 树渲染器
+
+Status: implemented
+
+[English](2026-07-28-local-json-tree-renderer.md) | 中文
+
+## 问题
+
+[轨迹检查记录表](../feature/2026-07-27-trajectory-inspection-ledger.md)使用的只读 JSON 检查器需要提供紧凑的对象和数组预览、供复制操作使用的明确数组路径、固定展开与可折叠两种根节点模式，以及键盘导航。`react-json-view-lite` 既不提供自定义节点渲染，也不提供行标识；要通过该依赖满足这些要求，就必须使用包管理器为编译后的发布文件打补丁，并遍历 DOM，从可见标签中还原数据路径。该补丁实际上相当于一个不受类型约束的 fork，但其源码映射与上游源码均未同步修改。
+
+## 决策
+
+`dsh-client-ui-primitives` 中的 `JsonTree` 自行负责递归呈现。
+
+- 每个渲染行都直接接收自身的值和属性路径。递归时，对象键和数组索引会附加到路径末尾，因此复制操作无需再从 DOM 渲染文本中反向还原应用数据。
+- 可展开行在本地渲染紧凑预览，仅在展开时挂载子行。`expandTopLevel` 可选择固定展开的括号框架或可折叠根节点，而不改变组件的公开契约。
+- 树中所有可见节点仅保留一个可通过 Tab 键聚焦的展开控件。使用指针激活控件后，该控件会成为 Tab 键焦点位置；上、下方向键循环移动焦点，左、右方向键折叠或展开当前焦点所在节点。
+- `react-json-view-lite` 不在 `dsh-client-ui-primitives` 的依赖项中，也没有 pnpm 补丁。针对性组件测试锁定预览、展开、键盘焦点和数组复制路径。
+
+## 曾考虑的替代方案
+
+**保留发布文件补丁。** 不予采纳：应用专用的渲染逻辑和数组标识契约仍会隐藏在生成的第三方文件中；每次更新依赖，都必须评审一个没有配套源码映射的 fork。
+
+**直接使用不提供预览的上游渲染器。** 不予采纳：`{…}` 和 `[…]` 会丢失轨迹检查器扫读时所需的紧凑载荷上下文。
+
+**渲染后注入预览和行元数据。** 不予采纳：Effect 或 MutationObserver 仍会依赖同一套私有 DOM 结构，同时使 React 和命令式变更机制分别负责同一行的不同部分。
+
+**采用更大型的 JSON 查看器。** 不予采纳：编辑、搜索与主题系统不在当前只读契约范围内；扩大依赖范围也无法去除检查器专用的复制和布局代码。
+
+## 后果
+
+JSON 检查器在源码层由单一实现负责，具有显式数据流和准确的数组路径，且没有经过补丁修改的依赖。`dsh-client-ui-primitives` 负责递归渲染、展开状态、ARIA 树结构和焦点循环移动行为，因此修改这些语义时必须提供针对性组件测试。实现有意保持只读，仅包含当前消费方使用的预览、导航与复制行为。

+# Agent Note: One shared base config with per-surface overlays
+
+Status: implemented
+
+English | [中文](2026-07-29-shared-base-config-overlays.zh.md)
+
+## Problem
+
+`dsh` shipped two full config trees that were 43 rows the same. `apps/cli/cordis.yml` composed the web surface as 74 flat rows, while the TUI booted `examples/tui-agent/cordis.yml`, whose single `@deepseek-ai/dsh-tui-demo` row mounted twelve plugins and re-declared their configuration as its own twenty-key pass-through `Config`.
+
+Neither file was what its location claimed. `examples/tui-agent` was not an example: `apps/cli/src/tui.ts` hardcoded it as the product's default config, and it owned the TUI PTY smoke, the eight terminal snapshot scenarios, and the PTY harness the `cordis-agent` leaf imported. `dsh-tui-demo` was not a demo either — it was the application, mounted by the shipped binary from `packages/examples/`.
+
+The duplication was the load-bearing problem. Of the 43 shared rows, 38 were byte-identical and 5 differed for a defensible per-surface reason, so every capability change had to be made twice and could silently drift. The bundle also inverted a default: `composeTuiApp` read `config.goals ?? {}`, so the shipped TUI mounted goals, `tool-goal`, `goal-session`, and `/goal` although no config key requested them.
+
+## Decision
+
+One shared base, one overlay per surface, composed as sibling patch lists.
+
+`apps/cli/config/base.cordis.yml` holds the 43 rows both surfaces mount. `apps/cli/config/tui.cordis.yml` and `apps/cli/config/web.cordis.yml` are **patch lists**, not trees: each states the handful of rows whose value is surface-specific and inserts its own rows. The launcher includes the base once and applies every overlay as a sibling patch list at **one** include level, because include patches never cross an include boundary — stacking overlays as nested includes would silently stop reaching base rows.
+
+Precedence is list order, last write winning per row: base, then the surface overlay, then either a `--config` overlay or the personal `~/.dsh/config.yaml`, then the launcher's own flag and profile patches.
+
+`--config ` now applies an overlay **instead of** the personal overlay, so a demo or test tree never inherits the user's provider and model. `--config-replace ` boots a file as the entire tree, bypassing base, surface overlay, and personal overlay alike; that is what the old `--config` did, so trees like `examples/web-cordis` moved to the new flag. Both flags survive the `/resume` execve handoff, or resuming would silently change the agent.
+
+A patch replaces its target row's whole `config` rather than merging, which shapes the split: a row whose value differs per surface lives in the overlays, never in the base, so no row is patched by three layers at once. Session identity therefore cannot ride a config key at all — it moved to `dsh-agent-loop`'s `CONFIGURED_AGENT_IDENTITIES_KEY`, as [the launcher-owned identity note](../architecture/2026-07-28-launcher-owned-resume-identity.md) now records.
+
+`examples/tui-agent`, `examples/cordis-agent`, `examples/code-mode`, and `packages/examples/tui-demo` are deleted. The TUI tests move to `apps/cli/tests/`, the cordis-toolset e2e to `packages/cordis/tool-cordis/tests/`, and the supported Code Mode demo remains the ACP overlay at `examples/acp-agent/code-mode.cordis.yml`.
+
+## Alternatives considered
+
+**Leave both trees flat and duplicated.** Rejected: 43 rows maintained twice is the defect, and a gate asserting they stay identical would freeze the duplication rather than remove it.
+
+**Nest the overlays as includes (`code-mode` → `tui` → `base`).** Rejected after testing the Loader: patches do not cross an include boundary, so the outer file's patches are dropped with only a warning. A three-level chain left `tools` unpatchable, and a base behind one include made every personal patch a silent no-op.
+
+**Put the union of all rows in the base and have each overlay disable what it does not want.** Rejected: the base stops meaning "shared", and each surface carries rows it exists only to switch off.
+
+**Keep the per-surface rows in the base and let overlays patch them.** Adopted only for the five rows that must exist in both trees, because a patch cannot create a row. Their base entries carry the plugin name and the config both surfaces share; each overlay states the rest.
+
+## Consequences
+
+An overlay or `--config` tree that named `@deepseek-ai/dsh-tui-demo`, or patched the `tui-agent` row, no longer resolves. Overlays now patch the row that owns each key: the model route on `agent-loop`, the persona on `system-prompt`, presentation on `tui`.
+
+A patch whose `id` matches no row stays a no-op rather than an error. That is deliberate: one personal overlay is shared across surfaces, and `insert` rows match nothing by design, so a row that exists only under `web` must not fail the TUI's boot.
+
+`dsh web` gains `--config`, threaded into `AppCLIEntry` as an extra overlay. Web keeps sandboxed Bash and filesystem providers plus approval, permission presets, directory picking, and browser permission UI; the overlay disables the shared local providers because patches can disable rows but cannot delete them. The TUI query index uses a unique process-local temporary database because the SQLite backend requires one writer owner. It is a disposable derived index rebuilt by each process; `/resume` lists the underlying corpus directly and does not depend on index reuse. `AppCLIEntry` reads both the base and its surface overlay when recovering row defaults for its own patch merge, since a flag override must preserve the overlay's other fields on the same row.

+Composition is checked by booting each tree through the real Loader and inspecting settled entries, not by reading YAML; both surfaces settle with zero unloaded rows, and Web starts its `httpServer` with sandboxed Bash and filesystem providers. Code Mode remains covered by the ACP overlay and programmatic TUI snapshots rather than a separate shipped TUI application.
+
+All eight terminal snapshot scenarios replay byte-identically after moving, and the 14-case PTY smoke passes, including two cases that assert a personal overlay reaches an **inserted** row — the behavior the vendored `plugin-include` fix enables ([`vendor/README.md`](../../../../vendor/README.md) local modification 8, covered by `packages/ui/app-boot/tests/config-reload.spec.ts`).
+
+Flattening surfaced three latent defects, each fixed here: the TUI captured the optional `sessionQuery` service once at construction and so could permanently disable `/resume` when it won the mount race; the shipped session-store root silently reverted to a project-local `./.sessions`; and `--config-replace` was dropped by the resume handoff.

+# Agent Note: 一份共享 base 配置加各 surface 的 overlay
+
+Status: implemented
+
+[English](2026-07-29-shared-base-config-overlays.md) | 中文
+
+## 问题
+
+`dsh` 交付了两棵完整的配置树，其中 43 个配置项完全相同。`apps/cli/cordis.yml` 以 74 个平铺配置项组合 web surface，而 TUI 启动的是 `examples/tui-agent/cordis.yml`——其中单独一行 `@deepseek-ai/dsh-tui-demo` 挂载了十二个插件，并把它们的配置重新声明为自己那份二十个键、仅作透传的 `Config`。
+
+这两份文件都名不副实。`examples/tui-agent` 并不是示例：`apps/cli/src/tui.ts` 把它硬编码为产品的默认配置；它还拥有 TUI 的 PTY 冒烟测试、八个终端快照场景，以及被 `cordis-agent` 叶节点 import 的 PTY harness。`dsh-tui-demo` 也不是 demo——它就是应用本身，由交付的二进制从 `packages/examples/` 中挂载。
+
+真正决定性的问题是重复。43 个共享配置项中，38 个逐字节相同，5 个因各 surface 的正当理由而不同；因此每次能力改动都必须改两处，而且可能无声漂移。该组合包还反转了一个默认值：`composeTuiApp` 读取 `config.goals ?? {}`，于是交付的 TUI 挂载了 goals、`tool-goal`、`goal-session` 和 `/goal`——尽管没有任何配置键要求它们。
+
+## 决策
+
+一份共享 base，每个 surface 一份 overlay，以平级 patch 列表的形式组合。
+
+`apps/cli/config/base.cordis.yml` 持有两个 surface 都会挂载的 43 个配置项。`apps/cli/config/tui.cordis.yml` 与 `apps/cli/config/web.cordis.yml` 是 **patch 列表**，不是配置树：各自声明少数取值因 surface 而异的配置项，并 insert 自己的配置项。启动器只 include base 一次，并把每个 overlay 作为**同一** include 层级上的平级 patch 列表应用——因为 include patch 不会跨越 include 边界，把 overlay 堆叠成嵌套 include 会使其静默地无法触达 base 配置项。
+
+优先级即列表顺序，逐配置项后写者胜：base，然后是 surface overlay，接着是 `--config` overlay 或个人 `~/.dsh/config.yaml`，最后是启动器自身的 flag 与 profile patch。
+
+`--config ` 现在应用一个 overlay 来**取代**个人 overlay，因此 demo 或测试用的树绝不会继承用户的 provider 与 model。`--config-replace ` 则把某个文件作为整棵树启动，同时绕过 base、surface overlay 与个人 overlay；这正是旧 `--config` 的行为，所以像 `examples/web-cordis` 这样的树改用了新 flag。两个 flag 都会在 `/resume` 的 execve 交接中保留，否则 resume 会静默更换 agent。
+
+patch 会整体替换目标配置项的 `config` 而不合并，这决定了拆分方式：取值因 surface 而异的配置项住在 overlay 中，绝不住在 base 里，从而没有任何配置项会被三层同时 patch。因此会话身份根本不能经由配置键传递——它迁移到了 `dsh-agent-loop` 的 `CONFIGURED_AGENT_IDENTITIES_KEY`，如[启动器持有身份的 note](../architecture/2026-07-28-launcher-owned-resume-identity.md) 现在所记录。
+
+`examples/tui-agent`、`examples/cordis-agent`、`examples/code-mode` 与 `packages/examples/tui-demo` 均被删除。TUI 测试迁往 `apps/cli/tests/`，cordis 工具集的 e2e 迁入 `packages/cordis/tool-cordis/tests/`，受支持的 Code Mode demo 则保留为 `examples/acp-agent/code-mode.cordis.yml` 中的 ACP overlay。
+
+## 备选方案
+
+**保留两棵平铺且重复的树。** 拒绝：43 个配置项维护两份正是缺陷本身，而用一个门禁断言二者保持一致只会固化重复，而非消除它。
+
+**把 overlay 嵌套成 include（`code-mode` → `tui` → `base`）。** 在对 Loader 实测后拒绝：patch 不会跨越 include 边界，因此外层文件的 patch 只会伴随一条告警被丢弃。三层链条使 `tools` 无法被 patch，而位于一层 include 之后的 base，会让每个个人 patch 都变成静默的空操作。
+
+**把所有配置项的并集放进 base，由各 overlay 禁用自己不需要的部分。** 拒绝：base 将不再意味着「共享」，而每个 surface 都要携带仅为将其关闭而存在的配置项。
+
+**把因 surface 而异的配置项留在 base 中，由 overlay 去 patch。** 仅对必须同时存在于两棵树中的那五个配置项采用，因为 patch 无法创建配置项。它们在 base 中的条目携带插件名与两个 surface 共享的配置，其余部分由各 overlay 声明。
+
+## 影响
+
+指名 `@deepseek-ai/dsh-tui-demo`、或 patch `tui-agent` 配置项的 overlay 与 `--config` 树将不再可解析。overlay 现在要 patch 拥有对应键的那一行：模型路由在 `agent-loop`，人设在 `system-prompt`，呈现设置在 `tui`。
+
+若某个 patch 的 `id` 不匹配任何配置项，Loader 仍只告警而不报错。这是有意为之：同一份个人 overlay 会跨 surface 共用，而 `insert` 配置项按设计本就不匹配任何目标，因此仅在 `web` 下存在的配置项不能让 TUI 启动失败。
+
+`dsh web` 新增 `--config`，作为一份额外 overlay 传入 `AppCLIEntry`。Web 保留沙箱化 Bash 与文件系统提供方，以及审批、权限预设、目录选择和浏览器权限界面；覆盖层会禁用共享的本地提供方，因为补丁可以禁用条目但不能删除条目。TUI 查询索引使用进程唯一的临时数据库，因为 SQLite 后端要求单写入者所有权。该索引是每个进程重新构建的可丢弃派生数据；`/resume` 直接列出底层语料，不依赖索引复用。`AppCLIEntry` 在为自身 patch 合并恢复配置项默认值时会同时读取 base 与其 surface overlay，因为 flag 覆盖必须保留同一配置项上 overlay 的其他字段。
+
+## 验证
+
+组合的正确性通过用真实 Loader 启动每棵树并检查已就绪的条目来核对，而不是靠阅读 YAML：两个界面都能稳定完成且没有未加载项；Web 会以沙箱化 Bash 与文件系统提供方启动 `httpServer`。Code Mode 继续由 ACP overlay 与程序化 TUI 快照覆盖，而不再维护独立交付的 TUI 应用。
+
+全部八个终端快照场景在迁移后逐字节重放一致，14 个用例的 PTY 冒烟测试全部通过，其中两个用例断言个人 overlay 能触达一个 **insert 进来的**配置项——这正是 vendored `plugin-include` 修复所启用的行为（[`vendor/README.md`](../../../../vendor/README.md) 本地修改第 8 条，由 `packages/ui/app-boot/tests/config-reload.spec.ts` 覆盖）。
+
+平铺过程暴露出三处潜伏缺陷，均在此一并修复：TUI 曾在构造时一次性捕获可选的 `sessionQuery` 服务，因此在挂载竞争中胜出时会永久禁用 `/resume`；交付的会话存储根目录曾静默退回项目本地的 `./.sessions`；`--config-replace` 曾在 resume 交接中被丢弃。

Prompt and tool bulk are scrubbed; one scenario per header class pins the remaining header sequence. The pin owns readable prompt and tool-schema sidecars by default, or names another pin as either source when the complete sequence is identical, so each distinct sidecar version is committed once. Fixture guards reject duplicate sidecar content, and record/refresh rejects shared claimants that generate different bytes. The original header-pinning rationale is preserved in the [header-pinning Agent Note](../../archived/testing/2026-07-06-pin-request-header-content-in-one-scenario.md).

 The surfaces are complementary: stdout covers the minimal automation wire, while JSONL covers loop, tool, and boundary structure that the wire intentionally omits.

The stdout expected output remains wire-shaped JSONL and every raw line must parse as JSON. Vitest updates only the stdout expected output; normalized session equality never overwrites the replay fixture.
+Normalization replaces session, cwd, protocol-id, timestamp, path, and process volatility while preserving deterministic sequence numbers.

 ## Consequences
 
-The tier adds reviewed per-scenario input, session, stdout, optional override, and optional workspace fixtures. Workspace seeds are copied into the generated cwd for both record and replay. In return the tier provides deterministic keyless coverage through the real Loader and tool composition. Most retained scenarios exercise the assembled backend rather than ACP; the [automation-only ACP decision](../simplification/2026-07-23-acp-automation-only-protocol.md#snapshot-boundary) keeps that corpus here and defers any move to a transport-neutral headless suite as an independent testing change (the suite-level FIXME marks it).

 This Agent Note relates to but does not supersede the [proposed determinism Agent Note](../../proposed/testing/2026-06-11-deterministic-and-stress-testing.md): that proposal's "universal replay fixture" re-derives session *message history* after every test (an internal-consistency invariant), whereas these snapshots pin assembled behavior plus the external automation output. They are complementary until the backend corpus moves off ACP.

 A plain shared-fixture module (the [testing-policy sanctioned shape](../../../../docs/testing.md)), not a package: the gate-worthy logic — replay derivation, session parsing, log scrubbing, persistence — lives in the gated packages `dsh-llm-replay`, `dsh-acp-snapshot`, and `dsh-session-persistence-jsonl`; what remains is boot wiring and browser glue, and chromium-driving code cannot hold per-file 100% coverage on the browserless coverage runners.
 
-`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.

 Keyless model displacement is the disabled adapter row plus `installLlmReplay` filling the open seam on the settled root ctx in providers-catalog mode — never catch-all: with the adapter row disabled no adapter exists, so catch-all would leave `resolveModelInfo` unroutable and `compact-basic`'s post-step pressure check would warn every step instead of being provably inert (the published 128k `contextWindow` keeps it inert for small fixtures). The direct install rather than an inserted replay plugin row is deliberate: it returns the `ReplayHandle` the teardown consumption check needs. A scenario with no fixture leaves the seam empty, so a stray stream fails loud with NO_ADAPTER.

 No single-shot transient-DOM assertions: every hop from replay yield to React commit can coalesce chunks, so sampling `[data-streaming]` is a race by construction. Streaming incrementality is asserted from the persisted `assistant/chunk` events (model-visible ⟺ logged makes the log the authoritative proof). `dsh-llm-replay`'s opt-in `paceMs` (default absent = burst) is a realism knob so the browser observes genuinely incremental SSE; correctness never leans on it, and abort during a pace wait cancels promptly.

No vitest retry on the lane; one chromium per file, fresh context per scenario, one host per scenario; viewport pinned; interaction selectors anchor on roles, `data-*` attributes, and visible text, while the frame and conversation-region captures use the existing CSS-module local-name anchors.

 ### CI stance
 
-The lane ships gate-exempt inside `pnpm run test:web`, exactly as that config's header records. Adding chromium to CI would reverse the "no browser infrastructure in CI" premise in the [GUI testing note](../process/2026-07-20-gui-testing-system.md) and therefore requires its own Agent Note cross-linked from there, staged as a non-required job first with measured promotion criteria (consecutive green runs, wall time, zero-retry flake budget, runner browser-cache strategy). `TODO(ci-browser)` marks the seam. Scenarios are POSIX-oriented (the lane is not in the Windows matrix).
+The lane is a required compare-only gate for Linux pull requests under the [browser snapshot CI decision](2026-07-30-web-browser-snapshot-ci-gate.md). The static job publishes `apps/web/dist` with the package build artifacts; the `node 24 / snapshots and artifacts` consumer job installs the lockfile-selected Chromium, restores its OS-and-lockfile-keyed cache, and runs the lane with `DSH_SNAPSHOT=replay`. This is an intentional plane split: the host and specs use the [tsx source-launch contract](../architecture/2026-07-29-dsh-source-launch-tsx-esm.md), while the browser consumes `apps/web/dist` and package `lib/client.js` artifacts, so the gate depends on `built-package-invariants` for those client artifacts. The hosted and self-hosted default-branch Linux serial jobs run the same gate; the hosted job produces the browser cache consumed by pull requests, while the persistent self-hosted pool needs no hosted cache. CI never records or refreshes goldens. Scenarios remain POSIX-oriented and stay outside the Windows and macOS matrices.

 ## Consequences
 
-The web surface gains its record-once/replay-forever tier: the real chromium → SSE → apiproxy → loop → tools → persistence chain runs keylessly in ~10-30s, deterministic across repeat runs, with fixtures owned and re-recordable by the lane itself. Costs accepted: every intentional conversation-UI change ends with a keyless `DSH_SNAPSHOT=refresh` (golden churn is reviewed diff, anchors keep semantic green); the aria format is Playwright-owned — the one committed snapshot format the repo does not control — so playwright version bumps must be deliberate bump-and-refresh commits (the dependency floats `^1.49.0` in `apps/web/package.json`; pin exactly if churn bites); replay's first-call-order binding constrains scenarios to one prompting session each, with the consumption assertion as the tripwire; `compact-basic` shares the session's replay cursor and stays inert only under the published 128k catalog window; and the lane guards regressions only where it runs (locally, `test:web`) until the CI reversal is separately decided.

+# Agent Note: Required CI gate for web browser expected outputs
+
+Status: implemented
+
+English | [中文](2026-07-30-web-browser-snapshot-ci-gate.zh.md)
+
+## Problem
+
+The [keyless web browser e2e lane](2026-07-24-web-gui-browser-e2e-lane.md) runs only under the local `pnpm run test:web` command, and PR CI does not compare `apps/web/tests/snapshots/**/*.expected.md`. A PR that changes user-visible web output can therefore remain green when its expected outputs are not refreshed; when any later branch explicitly runs `DSH_SNAPSHOT=refresh`, it backfills the earlier change and produces a diff unrelated to that branch. Ordinary local runs already default to read-only replay, so the gap is mandatory enforcement at the PR level, not a ban on writes in refresh mode.
+
+## Decision
+
+For Linux PRs, the `node 24 / snapshots and artifacts` job must run the full web browser replay/compare suite. `scripts/run-gates.ts` registers `test:web:built` as a `ci-consumers` gate and explicitly injects `DSH_SNAPSHOT=replay`; CI never runs in `record` or `refresh` mode, so when the committed goldens disagree with the currently assembled application, the tests fail directly instead of silently rewriting them on the runner and then passing.
+
+The static CI job already builds all publishable artifacts; it puts `apps/web/dist` and the package `lib/` directories in the built-tree artifact, which the consumer job reuses without rebuilding the entire repository. On hosted runners, CI installs Chromium and its system dependencies at the Playwright version in the lockfile. On the persistent failover VM, the image owns the Linux system packages and CI installs only Chromium, avoiding per-run `apt` mutation. The hosted default-branch Linux serial job runs the suite and produces the operating-system-and-lockfile-keyed browser cache; pull requests restore it without paying compression and upload on the required path, with an operating-system prefix fallback across lockfile changes. The self-hosted standby runs the same comparison without hosted cache actions.
+
+Local `pnpm run test:web` continues to build first and then run the full browser suite; `test:web:built` is the entry point for existing build artifacts. Developers explicitly run `DSH_SNAPSHOT=refresh pnpm run test:web` only after confirming that user-visible output changed intentionally, review every expected-output diff, and then verify again in replay mode that no files are written.
+
+For pull requests, the gate runs only in the Linux consumer job: these scenarios target POSIX, and the other PR jobs do not provision Chromium. The hosted and self-hosted default-branch Linux serial aggregates also include the comparison, while the macOS and Windows serial jobs remain browser-free. A PR's `all checks passed` verdict already depends on the consumer job, so a browser compare failure blocks the merge without requiring a new branch-protection check name.
+
+An observed self-hosted consumer run measured `web-snapshot` at 112.15 seconds and the full consumer aggregate at 114.97 seconds. The gate scheduler starts it as soon as `built-package-invariants` succeeds and runs independent gates concurrently, so it needs neither a dedicated job timeout nor a manual YAML ordering rule.
+
+## Alternatives considered
+
+**Continue requiring only local runs.** Rejected: execution depends on developer memory, which is precisely why stale goldens drift across PRs, and cannot guarantee that the PR introducing a behavior change carries its own expected-output diff.
+
+**Run CI in `refresh` mode and then check the working tree.** Rejected: checking after writing turns the assertion mechanism into a generator; if the working-tree check is wired incorrectly, it can turn a regression into a passing expected-output update. Replay compares the existing goldens directly and has a smaller failure surface.
+
+**Create a standalone browser job and rebuild the entire repository.** Rejected: it would duplicate dependency installation and the publishable build. The existing Linux consumer job already consumes the same built-tree artifact and is part of the unified required verdict.
+
+**Replace real Chromium with jsdom snapshots.** Rejected: jsdom does not cover the browser, HTTP/SSE carriage, or the composition of real client plugin bundles. It remains useful for fast lower-layer feedback, but cannot replace the assembled browser chain.
+
+## Consequences
+
+Before merge, every PR proves that the current web assembly matches all committed browser expected outputs, turning a missed refresh from an “unrelated change in a later PR” into a failure in the PR that introduced it. The cost is Chromium provisioning and one serial pass through the browser scenarios in the consumer job; built-artifact reuse and the browser cache avoid duplicate builds and downloads on reruns. The gate still makes no claim of cross-platform browser consistency, and if a Playwright/Chromium upgrade changes the ARIA format, the upgrade PR must explicitly refresh the expected outputs and review the churn.

+# Agent Note: Web 浏览器预期输出的必需 CI 门禁
+
+Status: implemented

+
+## 问题
+
+[无密钥 Web 浏览器 e2e 车道](2026-07-24-web-gui-browser-e2e-lane.md)只由本地 `pnpm run test:web` 运行，PR CI 不比较 `apps/web/tests/snapshots/**/*.expected.md`。因此，改变用户可见 Web 输出的 PR 可以在漏刷预期输出时保持绿色；后来任意分支显式运行 `DSH_SNAPSHOT=refresh`，都会替前序变更补账并产生与本分支无关的 diff。普通本地运行已经默认使用只读 replay，缺口是 PR 级的强制执行，而不是禁止 refresh 写入。
+
+## 决策
+
+Linux PR 的 `node 24 / snapshots and artifacts` 必须运行完整 Web 浏览器 replay/compare。`scripts/run-gates.ts` 把 `test:web:built` 作为 `ci-consumers` 的一个 gate，并显式注入 `DSH_SNAPSHOT=replay`；CI 永不以 `record` 或 `refresh` 模式运行，因此提交的 golden 与当前组装应用不一致时测试直接失败，不会在 runner 内静默改写后通过。
+
+静态 CI job 已经构建全部发布产物；它把 `apps/web/dist` 和包的 `lib/` 目录放进 built-tree 产物，消费方 job 复用该产物而不重复全仓构建。在托管运行器上，CI 按锁文件中的 Playwright 版本安装 Chromium 及其系统依赖。在持久化故障切换 VM 上，镜像负责预装 Linux 系统软件包，CI 只安装 Chromium，避免每次运行都通过 `apt` 改动系统。托管的默认分支 Linux 串行 job 运行该套件，并生成以操作系统和锁文件为键的浏览器缓存；PR 恢复该缓存，使必需路径无需承担压缩和上传开销，并可在锁文件变化时按操作系统前缀回退。自托管热备运行相同的比较，但不执行托管缓存操作。
+
+本地 `pnpm run test:web` 仍先构建再运行浏览器全集；`test:web:built` 是已有构建产物的执行入口。开发者只在确认用户可见输出有意变化后显式运行 `DSH_SNAPSHOT=refresh pnpm run test:web`，评审每一处 expected diff，再以 replay 模式复验不再写文件。
+
+对 PR 而言，门禁仅在 Linux 消费方 job 中运行：这些场景面向 POSIX，其他 PR job 不供给 Chromium。托管和自托管的默认分支 Linux 串行聚合作业也包含该比较，而 macOS 和 Windows 串行 job 仍不使用浏览器。PR 的 `all checks passed` 已依赖消费方 job，因此浏览器比较失败会阻止合并，无需新增 branch-protection check 名称。
+
+一次自托管消费方运行中，`web-snapshot` 实测耗时 112.15 秒，完整消费方聚合实测耗时 114.97 秒。gate 调度器会在 `built-package-invariants` 成功后立即启动它，并发运行彼此独立的 gate，因此既不需要专用 job 超时，也不需要手动制定 YAML 顺序规则。
+
+## 曾考虑的替代方案
+
+**继续只要求本地运行。** 已否决：执行依赖开发者记忆，正是旧 golden 跨 PR 漂移的原因，不能保证产生行为变化的 PR 自己携带 expected diff。
+
+**让 CI 以 `refresh` 模式运行后检查工作树。** 已否决：写后比较把断言机制变成生成器，若工作树检查接线失效就会把回归更新成绿色；replay 直接比较已有 golden，失败面更小。
+
+**新建独立 browser job 并重新构建全仓。** 已否决：它会重复依赖安装和发布构建。现有 Linux consumer job 已消费同一 built-tree artifact，并已被统一的 required verdict 聚合。
+
+**用 jsdom 快照代替真实 Chromium。** 已否决：jsdom 不覆盖浏览器、HTTP/SSE 承载及真实 client plugin bundle 组合；它保留为快速的下层反馈，不能替代 assembled browser chain。
+
+## 后果
+
+每个 PR 都在合并前证明当前 Web 组装与所有已提交的浏览器 expected 一致，漏刷从“后续 PR 的无关变化”变成引入 PR 自己的失败。成本是消费方 job 需要供给 Chromium，并串行运行一轮浏览器场景；built artifact 复用与浏览器缓存避免重跑时重复构建和下载。门禁仍不声称跨平台浏览器一致性，Playwright/Chromium 升级若改变 aria 格式，升级 PR 必须显式 refresh 并评审 churn。

+# Agent Note: Session projections and command lifecycle logging
+
+Status: proposed
+
+English | [中文](2026-07-27-session-projection-and-command-log.zh.md)
+
+## Problem
+
+Three in-flight web features — todo (#497), goal (#527), and plan mode (#587) — each derive per-session state from the session log and surface it in the browser client, and each invented its own copy of the same machinery:
+
+- **The client core class absorbs every domain.** All three add private fields, fetch choreography, and event switches to the client runtime's `Session` class and project their values through `ConversationSnapshot`. Plan alone adds seven private fields and a three-layer fence (request version, event version, latest-live cache); goal adds a write-revision fence plus a coalesced refetch loop; todo adds a projection field and an event case. A fourth domain means editing the core class a fourth time.
+- **Three baseline channels.** Todo rides a `todos` field on the history tail page — computed by `backscanTodos` **inside api-proxy**, business folding living in the carrier; plan adds a dedicated `session.planMode` unary; goal adds `goals.get`. Same problem, three wire shapes.
+- **Command results are unrecoverable.** `/goal`, `/plan`, and every other slash command return their outcome only in the `command.execute` RPC response, surfaced as a transient composer notice on the issuing tab. Nothing reaches the session log: a refresh, another tab, resume, or fork loses the record that the command ever ran. The domain *state* changes are durable (goal commits `goal/change` metadata, plan commits `plan/mode`), but the command invocation and its verdict are not.
+
+The underlying gap is architectural: the client has no seam for a plugin to observe session events in a session's scope and keep its own derived state, and the host has no uniform way to hand a client the current value of log-derived state whose history may have been paged out of the client's window.
+
+## Proposal
+
+Four infrastructure pieces, then the domains become pure contributors.
+
+### Whole-value event rule
+
+A state-carrying log event MUST carry the complete post-change state, never a bare delta. All three domains already comply: `todo/write` is a whole-list snapshot, `plan/mode` a whole boolean, `goal/change` metadata a full `GoalSnapshot` (or a whole-value clear tombstone). The rule keeps every domain's transition trivially cheap (the framework drives it per event), keeps values self-describing on the wire, and lets any consumer treat the latest pushed value as final — out-of-order immunity by seq comparison, self-healing because a missed update is corrected by the next one.
+
+### Host projection registry (`dsh-session-projection`, new package)
+
+A light interface package: the merge-extensible type map, the registry service, zod at the boundary. Capability-seam three-way split: domain host plugins contribute, carriers consume, neither knows the other.
+
+What a domain registers is a **state-driven computation unit** — three pure functions plus declarations — never an opaque getter. The framework owns driving it (subscription, watermark, caching, and later checkpointing); the domain owns only the mathematics. Projections serve every business domain (session title, plan, goal, permission, todos); commands are merely one trigger path and hold no special position in this contract.
+
+```ts ignore-check
+export interface SessionProjectionMap {}   // the single type table for the whole chain
+
+export interface ProjectionDefinition {
+  key: K
+  schema: ZodType  // validates the payload before it leaves the host
+  /** State for the empty log. */
+  init(): S
+  /** Pure transition: previous state + one event → next state. The framework drives it; domains hold no subscriptions. */
+  apply(state: S, event: SessionEvent): S
+  /** State → wire payload (the read-side projection). */
+  view(state: S): SessionProjectionMap[K]
+  /** State must be plain JSON (persisted-cache precondition); bump to invalidate persisted rows. */
+  stateVersion: number
+}
+
+declare module 'cordis' {
+  interface Context { sessionProjections: SessionProjectionRegistry }
+}
+```
+
+- Values are wire JSON payloads; the same map typed end to end (host unit, wire block, React hook) via `import type` — no second DTO table, no separate client-side "views" map. How a value is *rendered* is the slot system's business, never the projection layer's.
+- **The host is the only place a projection is computed.** The framework drives every registered unit forward eagerly: each committed session event passes through `apply`; a unit uninterested in an event returns the same state reference, and an unchanged reference (`Object.is`) produces no downstream work. Clients never fold domain events — they receive finished values (baseline block + push frame below). This removes the double-implementation trap (plan's two-event fold written once, on the host) and any client-side domain code.
+- **State is always computed, never logged.** The log holds events only; the unit's state lives in the framework's per-session watermark cache (`{state, observedSeq}` per unit) and, in a later phase, in a **persisted projection cache** on the domain-KV storage seam: rows of `(sessionId, key, ver, seq, val)` (`ver` = the unit's `stateVersion`, `seq` = the watermark, `val` = the state JSON). A row is never wrong, only possibly stale — its `seq` says exactly how stale. The one read recipe, cold and live alike: take the cached state (or `init()`), forward-apply only the events past its watermark, `view` the result. Cold listings (every session's title across all workspaces) become an index read plus, at worst, a short tail replay; the session-persistence seam grows a read-from-seq primitive for that tail in the same later phase. Write policy: throttled (count/interval, configurable) plus two mandatory points — `turn/end` and detach (the live-to-cold moment). A crash between writes costs a longer tail replay, never a wrong value.
+- A domain's input event set is its own choice: todos folds `todo/write` alone; plan folds `plan/mode` plus its own `/plan` `command/run` records (see the plan section); goal folds `goal/change` metadata; session title folds its title events (retiring the bespoke `session/title` frame and the client's title-snapshot map — the fourth hand-rolled projection this seam absorbs).
+- Registration is an effect (disposer with the fiber): an unloaded plugin's key disappears from subsequent responses and the client reads it as capability absence — HMR semantics for free. Duplicate keys throw. Domain plugins register under `ctx.inject(['sessionProjections'], …)` so headless assemblies without the registry stay unaffected.
+- The package owns `./invariant` (every served key has a live registration).
+
+### Wire: projections block on the history tail page
+
+```ts ignore-check
+// session.history response, tail page only (beforeSeq absent):
+{ events, hasMore,
+  projections?: { asOfSeq: number, values: Partial } }
+```
+
+The api-proxy history handler, after slicing the tail page, synchronously walks the registry — no `await` anywhere, so every key's value and `asOfSeq` form one consistent cut. `asOfSeq` is the **last event's seq** (`session.seq - 1`; `-1` for an empty log, the same vocabulary as `session/subscribed.lastSeq`), so a push frame carrying the first post-baseline change always compares strictly greater. Api-proxy holds zero domain knowledge (the same carrier/contributor relationship as `viewFor` against `ctx.tools`).
+
+No new RPC method. The timing coincidence is exact: every moment the client needs a fresh baseline (open, reconnect resync, gap repair) already pulls the tail page, and the only path that never needs one (loadOlder) is the only path that passes `beforeSeq`. The client therefore has **no** independent "refetch the baseline" decision at all. Window content is never a signal: "no domain event in the window" is unanswerable there by construction, and only the baseline answers it.
+
+Retired by this block: `session.planMode` and `setPlanMode` (both sides — plan selection goes through the standard command channel, see the plan section), `goals.get` (read side; the six mutation RPCs stay, their responses no longer feed state — the mux event arrives anyway), the `todos` rider field, and `backscanTodos` in api-proxy (moves into the todo domain's unit, in `tool-todo`).
+
+### Push frame and the client value store (domains write zero client code)
+
+Because the host is the only computation site, finished values reach clients over one new mux frame:
+
+```ts ignore-check
+// MuxFrame union + schema branch:
+{ type: 'session/projection', sessionId, key: string, value: unknown, seq: number }
+```
+
+The framework emits it whenever a unit's state reference changes (`Object.is` gate above); `seq` is the unit's watermark at emission. This is live push state, never logged — the same posture as the tool-view `view` slot: replay recomputes on the host.
+
+The client object layer keeps one **generic value store** per session: `key → { value, seq }`, seeded by the tail page's projections block and updated by the frame, under the single rule **higher seq wins**. Replayed baselines cannot roll a newer frame back; a lost frame costs staleness until the next frame or baseline, never wrongness. No `fromEvent`, no per-domain cell registration, no client-side domain folding — a domain ships projection support with **zero client code** (the `SessionProjectionMap` merge serves both sides through the `/types` outlet). The bespoke `session/title` frame and the manager's title-snapshot map retire into this generic pair. All the per-domain fences (#587's three layers, #527's write revision) dissolve into the one seq rule.
+
+### Plan through the standard command channel (worked example)
+
+Plan mode demonstrates the full pattern — trigger path, run plane, and replay plane, cleanly separated:
+
+- **Trigger path**: the web plan toggle sends `/plan` / `/plan off` through `command.execute` like any other command; the dedicated `setPlanMode`/`planMode` RPCs are retired. The user's *request* is durably recorded as that command's `command/run { name: 'plan', args: 'off' | '' }` — structured fields, no line parsing.
+- **Run plane** (unchanged): the plan-mode service keeps its in-memory pending intent and flushes `plan/mode` at the next turn boundary. On cold start the service rebuilds its intent queue from the replay plane ("empty run state means the replay state").
+- **Replay plane**: plan's projection unit folds **two** event types — its own `command/run` records set `wanted`; `plan/mode` sets `active` and clears `wanted`; `view` derives `{ active, pending: wanted !== null && wanted !== active }`. Pending is thereby a pure replay quantity: host restarts recover it, other tabs fold the same events (cross-tab pending for free), and a cold read answering `{ active: false, pending: true }` is accurate ("an unfulfilled selection awaits resume").
+
+A domain's input event set is its own choice — that is the general rule this example instantiates. Whether "the user asked for X" appears in a projection (plan folds its command records) or only in the flow (the command node renders anyway) is per-domain semantics, never a framework concern.
+
+### React: `useProjection`, the fifth framework hook seat
+
+The existing four seats cannot host this state (store discipline bans business objects; inject bans hooks; `ConversationSnapshot` is being evacuated). `useProjection` becomes a framework seat, minted in web-react (the one hook constructor), delivered through the same standard-kit channel as `useSession` (`provideInfo` → SessionProvider → props):
+
+```ts ignore-check
+type UseProjection = {
+  (key: K): SessionProjectionMap[K] | undefined
+  (
+    key: K, selector: (v: SessionProjectionMap[K] | undefined) => S,
+    eq?: (a: S, b: S) => boolean): S
+}
+```
+
+`undefined` uniformly means capability absent (host plugin unmounted, or no baseline/frame has carried the key). The value store exposes bare per-key `{subscribe, getSnapshot}` faces; `bindSnapshotSelector` with per-key caching does the rest — reference stability holds because a key's value reference changes only when a frame or baseline lands. Write paths are unchanged: mutation callbacks stay in the inject share (callbacks out of inject, live state out of `useProjection`).
+
+The one existing violation of "no hooks through inject" — `DetailsInjected.useSelection` — is folded in with this change: selection is viewing state living in the chat store, so the details registration declares the shared store handle and the component reads `props.useStore(s => s.selection)`; `useSelection` leaves the inject contract.
+
+### Command lifecycle in the log
+
+Two log-only (non-surface, model-invisible) events, mirroring the `tool/call`/`tool/result` pairing:
+
+```ts ignore-check
+'command/run':  { commandId: string; name: string; args: string; source: CommandSource }
+'command/done': { commandId: string; kind: 'success' | 'error'; text?: string }
+```
+
+The host command executor (`packages/ui/commands`) appends `command/run` before invoking the handler and `command/done` at settlement — direct standalone appends on the receiving agent's session, in the same shape as every other plugin-owned log-only event after the [synthetic-turn removal](../../implemented/simplification/2026-07-28-remove-synthetic-log-only-turns.md): no turn wraps them (turns describe model-loop executions only), persistence drains them at ordinary checkpoints, and the commands package's own invariant companion enforces the run/done pairing. The payload is structured — `name` and `args` are the parser's own split (`parseCommand`'s name and rawInput), so a consumer (a projection unit folding its own command records, a rich command card) never re-parses a line. `text` is the handler's verbatim outcome — factual data of the same nature as `tool/result.content`, not presentation (how it is laid out remains client-computed at render time, satisfying the "presentation never enters the log" red line). Domains that want the model to know the outcome keep doing what they do today (plan's narration, goal's inject) — that is a domain decision, unchanged.
+
+Because committed events broadcast on the mux stream, refresh persistence, multi-tab sync, and fork/resume recovery all come for free. The `command.execute` RPC degrades to admission — `{ matched, commandId? }`: whether the line resolved, and the minted pairing id when it did, so the issuing client can correlate its request with the flow node the lifecycle events produce. The one-shot notice channel (`runDetached` → `noticeFor`) is retired.
+
+The client flow builder gains one generic command node (run/done paired by `commandId`; cross-window cuts soft-fall like tool pairs). Rendering goes through a new keyed slot `'conversation.chat.commandview'`, key = command name, **fallback = a generic command card** (zero registration required — the former notice text now renders durably in the flow). A domain upgrades by registering one row component, drawing on `command/run`'s structured fields and its own projection value (`useProjection`) — the same shape as tool rows after the toolview dissolution.
+
+## Delivery plan
+
+Infrastructure first; the three in-flight PRs are left untouched and re-target after the base lands (their migration mapping is the guide):
+
+1. **Host base**: `dsh-session-projection` (unit contract, eager drive, watermark cache) + api-proxy projections block + the `session/projection` push frame. Mergeable with zero domains registered (block and frames simply absent).
+2. **Client base**: the generic value store + `useProjection` seat; retire the per-domain cell machinery and, with title's unit registered, the `session/title` frame and title-snapshot map. Depends on 1 for the frame shape (fixtures feed synthetic frames meanwhile).
+3. **Command channel**: the two events, executor logging, generic node + keyed slot, notice retirement, `{matched, commandId?}` admission. Parallel with 1.
+4. **Domain re-targets** (after 1+2): todo (unit in `tool-todo`, drop the rider field), then plan (two-event unit, RPCs retired, toggle → `/plan`), then goal (`goal/change` unit, drop `goals.get`, move the six `Session` methods into the domain plugin's inject).
+5. **Persisted projection cache** (later phase, after the domain-KV storage seam): the `(sessionId, key, ver, seq, val)` rows, throttled writes with turn/end + detach mandatory points, and the persistence read-from-seq primitive for cold tail replay.
+
+## Alternatives considered
+
+**A dedicated `session.projections` RPC** — rejected: baseline-refresh moments coincide exactly with tail-page pulls, so a separate unary buys a second round-trip, a second seq to reconcile, and a client-side "when to refetch" decision that the rider design deletes outright.
+
+**An opaque `get(agent)` provider contract** — rejected after being the first draft: with the computation model hidden inside the domain, the framework can never checkpoint the state, serve cold sessions (no agent, no loaded log — `get` has nothing to run against), or resume from a mid-log position. Registering the `(init, apply, view)` unit hands the framework the drive and keeps the domain to pure mathematics; a domain with host-side behavioral needs still keeps its own service subscriptions independently of the projection unit.
+
+**A live-only overlay hook (`live?(agent, base)`) for plan's pending intent** — rejected: it existed solely because the user's plan *selection* was not in the log. Routing the selection through the standard command channel puts `command/run` on the account, pending becomes a pure replay quantity, and the projection contract stays exactly three pure functions.
+
+**Naming the seam `registerFold`** — superseded by the unit contract: the registered object now genuinely is a fold, but `fold*` in this repo names pure `(events) => state` helper functions while this seam registers a keyed, schema'd, versioned unit. Projection remains the event-sourcing term for the read-model role, and both #587's note title and #497's comments already use it.
+
+**Client-side folding (per-domain projection cells with a `fromEvent`)** — rejected after being the second draft: once plan's unit folds two event types, a client cell must duplicate the host's transition logic in the browser — the same fold written twice, evolving separately. Pushing finished values (the title-frame precedent, generalized) keeps one computation site and reduces the client to a generic seq-guarded value store; domains write zero client code.
+
+**Bounded reverse scan over the log tail (absorber declarations)** — rejected for now: nothing supports it today, it only serves domains whose every event carries the full folded state, and the persisted projection cache covers the same cold-read need uniformly (cache row + forward tail replay — the same recipe as the client's baseline + catch-up, and as paged loading). Revisit only if a real cold-read path emerges that checkpointing cannot serve.
+
+**An `invalidate`-style cell (mark dirty, refetch on domain events)** — rejected: it exists only to serve delta events. The whole-value rule makes every domain last-wins; goal's refetch loop, its coalescing, and its stale-read fence all disappear.
+
+**Hanging the registry off `ctx.apiProxy`** — rejected: session projections are not web-specific (TUI, ACP, headless are future consumers), and domain packages must not depend on the apiproxy package. The independent seam also deletes #587's type-only import edge from api-proxy into the plan package.
+
+**A separate client-side `SessionProjectionViews` type table** — rejected: one `SessionProjectionMap` typed end to end is the wire-passthrough discipline (no second DTO vocabulary); values are JSON payloads and rendering belongs to slots.
+
+**Event-broadcast collection instead of a registry walk** — rejected: async listeners cannot yield the single synchronous cut that makes `asOfSeq` one consistent snapshot across all keys; registries are this repo's shape for contributions (`ctx.tools`, prompt sections, slots).
+
+**A dedicated `plan/select` selection event (structured domain event instead of folding command records)** — rejected in favor of the command channel: `command/run`'s structured `{name, args}` already records the selection, the `/plan` grammar and its fold live in the same plugin (domain-internal coupling, not cross-domain), and one less event type. The handler must call `set()` before any failable path so the logged request and the run plane cannot diverge — a domain-internal ordering constraint, documented at the handler.
+
+**Keeping `setPlanMode` as a dedicated RPC** — rejected: plan selection is a user command like any other; the command channel gives it durable recording, flow rendering, multi-tab visibility, and admission semantics without a bespoke wire method. Web UI affordances (a toggle) compose the command line internally.
+
+**Making mutation RPC responses feed cell state** — rejected: the committed mux event arrives immediately and carries the same whole value with a seq; responses feeding state is what required #527's write-revision fence.
+
+## Acceptance criteria
+
+- A domain plugin ships per-session log-derived state to React by writing only: the whole-value event declaration, one host unit `register`, its `SessionProjectionMap` merge, and inject callbacks — zero client-side code, no edits to the client `Session` class, `ConversationSnapshot`, api-proxy, or the wire schema files.
+- The history tail page carries `projections` with `asOfSeq` equal to the window tail seq; loadOlder pages never carry it; a deployment without the registry serves histories without the block and clients treat every key as absent.
+- A stale baseline cannot overwrite a newer `session/projection` frame, and a replayed frame cannot regress the value store (higher-seq-wins tests on both paths).
+- A slash command executed on one tab renders a durable node in the flow on refresh, on a second tab, and after resume; unregistered commands render the generic card; the composer notice path for command outcomes is gone.
+- `useProjection` reaches components through the standard props kit; no hook crosses an inject contract (including `useSelection`).
+- Session titles ride the generic pair (baseline block + projection frame); the bespoke `session/title` frame and the client title-snapshot map are gone.
+
+## Risks
+
+- **Whole-value rule is load-bearing**: a future domain logging bare deltas cannot serve consumers from its latest event and complicates its own unit. Mitigation: the rule is stated here and in the projection package README; the unit contract makes the full state explicit at every transition.
+- **Synchronous unit discipline**: `init`/`apply`/`view` that await would tear the consistency cut. The registry documents and the invariant companion asserts synchronicity as far as practical; review owns the rest.
+- **Live registry churn is not pushed**: loading or unloading a domain plugin mid-session changes the key set, but no session event fires and no frame is pushed; open clients hold the stale key until the next tail pull (reconnect, gap repair, open). Accepted as a dev-only (HMR) staleness window — a registry-change push can be added to the change feed later without contract impact.
+- **Eager drive costs on busy sessions**: every committed event passes every registered unit's `apply`. Units are cheap per-event by construction (whole-value rule), non-matching events return the same reference, and the count of registered domains is small; if a hot path ever shows, per-unit event-type prefilters can be added without contract change.
+- **Projection payload growth**: every tail page carries every registered key. Payloads are whole values of UI-scale state (a todo list, a goal snapshot); if a future domain's value is large, per-key opt-out or lazy keys can be added to the request without changing the model.
+- **Command log volume**: two log-only events per slash command; bounded by human command frequency, negligible against chunk volume.
+- **Re-target churn**: three open PRs rebase onto a moved foundation. Accepted cost of infrastructure-first; the migration mapping section in the design ledger names each PR's keep/drop list.

+
+## Problem
+
+三个在途的 web 功能——todo（#497）、goal（#527）、plan mode（#587）——都要从会话日志推导按会话的状态并呈现到浏览器客户端，而三者各自发明了一套同样的机制：
+
+- **客户端核心类吸收每一个领域。** 三者都往客户端运行时的 `Session` 类里添加私有字段、拉取编排和事件 switch 分支，并经 `ConversationSnapshot` 投出各自的值。仅 plan 一家就加了七个私有字段和三层栅栏（请求版本、事件版本、最新活值缓存）；goal 加了写 revision 栅栏外加一个合并式重取循环；todo 加了一个投影（projection）字段和一条事件 case 分支。再来第四个领域，就要第四次改动核心类。
+- **三条基线通道。** todo 搭在历史尾页的 `todos` 字段上——由 **api-proxy 内部**的 `backscanTodos` 计算，业务折叠（fold）逻辑寄居在载体里；plan 加了一个专用的 `session.planMode` 一元 RPC；goal 加了 `goals.get`。同一个问题，三种协议格式（wire format）。
+- **命令结果不可恢复。** `/goal`、`/plan` 以及其余所有斜杠命令都只在 `command.execute` RPC 响应里返回结果，以一条转瞬即逝的 composer 通知呈现在发起命令的标签页上。会话日志里什么也留不下：刷新、另开标签页、恢复或 fork 都会丢掉「该命令曾经运行过」的记录。领域*状态*变更是持久的（goal 提交 `goal/change` 元数据，plan 提交 `plan/mode`），但命令调用本身及其结论不是。
+
+底层缺口是架构性的：客户端没有一个 seam 让插件在会话 scope 内观察会话事件并维护自己的派生状态；host 侧也没有统一的方式把日志派生状态的当前值交给客户端——而该状态的历史可能已被分页挤出客户端窗口之外。
+
+## Proposal
+
+先立四件基础设施，之后各领域都退化为纯贡献方。
+
+### 全量值事件规则
+
+携带状态的日志事件必须携带变更后的完整状态，绝不携带裸增量。三个领域现状已然合规：`todo/write` 是整表快照，`plan/mode` 是一个完整布尔值，`goal/change` 元数据是完整的 `GoalSnapshot`（或一个全量值清除墓碑）。该规则让每个领域的状态转移始终足够廉价（框架逐事件驱动它），让值在协议层自描述，并让任何消费方都可以把最近推送的值当作最终值——靠 seq 比较获得乱序免疫，且自愈：漏掉的更新会被下一次更新纠正。
+
+### host 侧投影注册表（`dsh-session-projection`，新包）
+
+一个轻量的接口包（package）：merge-extensible 类型表、注册表服务、边界上的 zod 校验。能力 seam 三方拆分：领域 host 插件负责贡献，载体负责消费，两侧互不相识。
+
+领域注册的是一个**状态驱动计算单元（state-driven computation unit）**——三个纯函数外加若干声明——绝不是一个不透明的 getter。驱动它是框架的职责（订阅、水位线（watermark）、缓存，以及后续的检查点机制），领域只负责数学本身。投影服务于所有业务领域（会话标题、plan、goal、权限、todos）；命令只是其中一条触发路径，在本契约中没有任何特殊地位。
+
+```ts ignore-check
+export interface SessionProjectionMap {}   // the single type table for the whole chain
+
+export interface ProjectionDefinition {
+  key: K
+  schema: ZodType  // validates the payload before it leaves the host
+  /** State for the empty log. */
+  init(): S
+  /** Pure transition: previous state + one event → next state. The framework drives it; domains hold no subscriptions. */
+  apply(state: S, event: SessionEvent): S
+  /** State → wire payload (the read-side projection). */
+  view(state: S): SessionProjectionMap[K]
+  /** State must be plain JSON (persisted-cache precondition); bump to invalidate persisted rows. */
+  stateVersion: number
+}
+
+declare module 'cordis' {
+  interface Context { sessionProjections: SessionProjectionRegistry }
+}
+```
+
+- 值就是协议层的 JSON 载荷；同一张类型表经 `import type` 端到端贯通（host 侧单元、协议块、React 钩子）——没有第二张 DTO 表，也没有独立的客户端「views」表。值如何*渲染*是 slot 体系的事，永远不归投影层管。
+- **host 是投影唯一的计算地点。** 框架正向驱动（eager drive）每个已注册的单元：每个已提交的会话事件都经过 `apply`；对某事件不感兴趣的单元返回同一个状态引用，而引用未变（`Object.is`）就不产生任何下游工作。客户端从不折叠领域事件——它们收到的是成品值（基线块 + 下文的推送帧）。这消除了双重实现陷阱（plan 的双事件折叠只在 host 写一遍），也消除了一切客户端侧领域代码。
+- **状态永远靠计算得出，绝不入日志。** 日志只存事件；单元的状态住在框架的按会话水位线缓存里（每单元一份 `{state, observedSeq}`），并在后续阶段进入 domain-KV 存储 seam 上的**持久投影缓存（persisted projection cache）**：形如 `(sessionId, key, ver, seq, val)` 的行（`ver` = 单元的 `stateVersion`，`seq` = 水位线，`val` = 状态 JSON）。一行永远不会是错的，至多是陈旧的——其 `seq` 精确说明陈旧到哪。冷读与活读共用同一套读取配方：取缓存状态（或 `init()`），只对超出其水位线的事件做正向 `apply`，再对结果做 `view`。冷列表（跨全部 workspace 列出每个会话的标题）变成一次索引读，至多外加一小段尾部回放；session-persistence seam 在同一后续阶段为这段尾部补一个按 seq 起读的原语。写入策略：节流（次数/间隔，可配置）外加两个强制点——`turn/end` 与 detach（由活转冷的时刻）。两次写入之间崩溃的代价是尾部回放更长一些，绝不会是值出错。
+- 领域的输入事件集由领域自己选择：todos 只折叠 `todo/write`；plan 折叠 `plan/mode` 外加它自己的 `/plan` `command/run` 记录（见 plan 一节）；goal 折叠 `goal/change` 元数据；会话标题折叠其标题事件（顺带下线专设的 `session/title` 帧与客户端的标题快照表——这是该 seam 收编的第四个手工投影）。
+- 注册是 effect（disposer 随 fiber 走）：插件卸载后其 key 从后续响应中消失，客户端将其读作能力缺失——HMR（热模块替换）语义随之自动成立。key 重复直接 throw。领域插件在 `ctx.inject(['sessionProjections'], …)` 下注册，因此不带注册表的 headless 组装完全不受影响。
+- 该包拥有 `./invariant`（每个被服务的 key 都有一条存活的注册）。
+
+### 协议层：历史尾页上的 projections 块
+
+```ts ignore-check
+// session.history response, tail page only (beforeSeq absent):
+{ events, hasMore,
+  projections?: { asOfSeq: number, values: Partial } }
+```
+
+api-proxy 的历史处理器切出尾页后同步遍历注册表——全程没有一个 `await`，因此所有 key 的值与 `asOfSeq` 构成同一个一致切面。`asOfSeq` 是**最后一个事件的 seq**（`session.seq - 1`；空日志为 `-1`，与 `session/subscribed.lastSeq` 同一套词汇），因此携带基线之后首个变更的推送帧在比较时恒严格更大。api-proxy 不持有任何领域知识（与 `viewFor` 面向 `ctx.tools` 是同一种载体/贡献方关系）。
+
+不新增 RPC 方法。时机上的重合是精确的：客户端每一个需要新基线的时刻（打开、重连重同步、缺口修补）本来就要拉尾页，而唯一永远不需要基线的路径（loadOlder）恰好是唯一传 `beforeSeq` 的路径。因此客户端**完全没有**独立的「重取基线」决策。窗口内容从不充当信号：「窗口里没有该领域的事件」这个问题在窗口内从构造上就无法回答，只有基线能回答它。
+
+随此块下线的旧通道：`session.planMode` 与 `setPlanMode`（读写两侧——plan 选择改走标准命令通道，见 plan 一节）、`goals.get`（读侧；六个变更 RPC 保留，但其响应不再喂状态——mux 事件反正会到）、`todos` 搭载字段，以及 api-proxy 里的 `backscanTodos`（移入 todo 领域的单元，落在 `tool-todo`）。
+
+### 推送帧与客户端值仓（领域零客户端代码）
+
+既然 host 是唯一计算地点，成品值经一个新的 mux 帧送达客户端：
+
+```ts ignore-check
+// MuxFrame union + schema branch:
+{ type: 'session/projection', sessionId, key: string, value: unknown, seq: number }
+```
+
+只要某单元的状态引用发生变化（上文的 `Object.is` 闸门），框架就发出该帧；`seq` 是发出时该单元的水位线。这是实时推送状态，绝不入日志——与 tool-view 的 `view` slot 同一姿态：回放时在 host 重新计算。
+
+客户端对象层为每个会话维护一个**通用值仓（value store）**：`key → { value, seq }`，由尾页的 projections 块播种、由该帧更新，唯一规则是 **seq 高者胜**。重放的基线无法把更新的帧往回滚；丢失一个帧的代价只是陈旧——到下一个帧或基线为止——绝不会出错。没有 `fromEvent`，没有按领域的 cell 注册，没有客户端侧领域折叠——领域交付投影支持只需**零客户端代码**（`SessionProjectionMap` merge 经 `/types` 出口同时服务两侧）。专设的 `session/title` 帧与 manager 的标题快照表都收编进这对通用机制。所有按领域自造的栅栏（#587 的三层、#527 的写 revision）都消融进这一条 seq 规则。
+
+### plan 走标准命令通道（完整示例）
+
+plan mode 完整演示了这套模式——触发路径、运行面、回放面，三者干净分离：
+
+- **触发路径**：web 的 plan 开关像任何其他命令一样经 `command.execute` 发送 `/plan` / `/plan off`；专设的 `setPlanMode`/`planMode` RPC 下线。用户的*请求*被持久记录为该命令的 `command/run { name: 'plan', args: 'off' | '' }`——结构化字段，无需解析行文本。
+- **运行面**（不变）：plan-mode 服务在内存里保持待定意图，并在下一个轮次边界落下 `plan/mode`。冷启动时服务从回放面重建其意图队列（「运行态为空即以回放态为准」）。
+- **回放面**：plan 的投影单元折叠**两**种事件——它自己的 `command/run` 记录设置 `wanted`；`plan/mode` 设置 `active` 并清除 `wanted`；`view` 推导出 `{ active, pending: wanted !== null && wanted !== active }`。待定态由此成为纯回放量：host 重启能恢复它，其他标签页折叠同样的事件（跨标签页待定态随之自动获得），冷读回答 `{ active: false, pending: true }` 也是准确的（「一个未兑现的选择正等待恢复」）。
+
+领域的输入事件集由领域自己选择——本示例落实的正是这条一般规则。「用户请求过 X」是出现在投影里（plan 折叠自己的命令记录），还是只出现在 flow 里（命令节点反正会渲染），属于各领域自己的语义，永远不是框架的关切。
+
+### React：`useProjection`，第五个框架钩子席位
+
+既有四个席位都装不下这份状态（store 纪律禁止业务对象；inject 禁止钩子；`ConversationSnapshot` 正在被清退）。`useProjection` 成为一个框架席位，在 web-react（唯一的钩子铸造点）铸造，经与 `useSession` 相同的标准套件通道（`provideInfo` → SessionProvider → props）送达：
+
+```ts ignore-check
+type UseProjection = {
+  (key: K): SessionProjectionMap[K] | undefined
+  (
+    key: K, selector: (v: SessionProjectionMap[K] | undefined) => S,
+    eq?: (a: S, b: S) => boolean): S
+}
+```
+
+`undefined` 统一表示能力缺失（host 插件未挂载，或尚无任何基线/帧携带过该 key）。值仓只暴露按 key 的裸 `{subscribe, getSnapshot}` 面；其余交给带逐 key 缓存的 `bindSnapshotSelector`——引用稳定性成立，因为一个 key 的值引用只在帧或基线落地时才变化。写路径不变：变更回调留在 inject 共享面（回调出自 inject，活状态出自 `useProjection`）。
+
+「钩子不得穿过 inject」的唯一既有违例——`DetailsInjected.useSelection`——随本变更一并收编：选中态是住在聊天 store 里的查看状态，因此 details 注册声明共享 store 句柄，组件改读 `props.useStore(s => s.selection)`；`useSelection` 退出 inject 契约。
+
+### 日志中的命令生命周期
+
+两个仅日志（非 surface、模型不可见）事件，镜像 `tool/call`/`tool/result` 的配对：
+
+```ts ignore-check
+'command/run':  { commandId: string; name: string; args: string; source: CommandSource }
+'command/done': { commandId: string; kind: 'success' | 'error'; text?: string }
+```
+
+host 侧命令执行器（`packages/ui/commands`）在调用处理器前追加 `command/run`，在结算时追加 `command/done`——在接收 agent 的会话上直接独立追加，与[合成轮次移除](../../implemented/simplification/2026-07-28-remove-synthetic-log-only-turns.md)之后所有插件自有 log-only 事件同一形状：没有轮次包裹它们（轮次只描述模型循环执行），持久化在常规检查点排空它们，run/done 配对由 commands 包自己的 invariant 伴生插件把守。载荷是结构化的——`name` 与 `args` 就是解析器自己的切分（`parseCommand` 的 name 与 rawInput），因此消费方（折叠自己命令记录的投影单元、富命令卡片）永远无需重新解析行文本。`text` 是处理器的原样结果——与 `tool/result.content` 同一性质的事实数据，不是呈现（版式如何编排仍由客户端在渲染时计算，满足「呈现永不入日志」这条红线）。想让模型知道结果的领域继续做它们今天在做的事（plan 的旁白、goal 的注入）——那是领域自己的决定，保持不变。
+
+由于已提交事件会在 mux 流上广播，刷新后仍在、多标签页同步、fork/恢复后可还原这三件事随之全部自动获得。`command.execute` RPC 退化为准入判定——`{ matched, commandId? }`：该行是否匹配命中，以及命中时新铸的配对 id，发起命令的客户端据此把自己的请求与生命周期事件产出的 flow 节点关联起来。一次性通知通道（`runDetached` → `noticeFor`）就此下线。
+
+客户端 flow 构建器新增一个通用命令节点（run/done 按 `commandId` 配对；跨窗口截断时与工具配对同样软降级）。渲染走一个新的 keyed slot `'conversation.chat.commandview'`，key = 命令名，**兜底 = 通用命令卡片**（零注册即可用——从前的通知文本现在持久地渲染在 flow 里）。领域要升级展示，只需注册一个行组件，取材于 `command/run` 的结构化字段与自己的投影值（`useProjection`）——与 toolview 解散之后的工具行同一形状。
+
+## Delivery plan
+
+基础设施先行；三个在途 PR（Pull Request）原样不动，待基座落地后重新对接（它们的迁移映射即指南）：
+
+1. **host 基座**：`dsh-session-projection`（单元契约、正向驱动、水位线缓存）+ api-proxy 的 projections 块 + `session/projection` 推送帧。零领域注册也可合入（此时块与帧直接缺席）。
+2. **客户端基座**：通用值仓 + `useProjection` 席位；下线按领域的 cell 机制，并在标题单元注册后一并下线 `session/title` 帧与标题快照表。帧的形状依赖 1（在此之前 fixture（测试前置数据）喂合成帧）。
+3. **命令通道**：两个事件、执行器落日志、通用节点 + keyed slot、通知通道下线、`{matched, commandId?}` 准入。与 1 并行。
+4. **领域重新对接**（在 1+2 之后）：先 todo（单元进 `tool-todo`，删掉搭载字段），再 plan（双事件单元、RPC 下线、开关改发 `/plan`），最后 goal（`goal/change` 单元，删掉 `goals.get`，把六个 `Session` 方法移入领域插件的 inject）。
+5. **持久投影缓存**（后续阶段，待 domain-KV 存储 seam 就绪后）：`(sessionId, key, ver, seq, val)` 行、带 turn/end 与 detach 强制点的节流写入，以及持久化侧供冷尾部回放用的按 seq 起读原语。
+
+## Alternatives considered
+
+**专设一个 `session.projections` RPC**——不予采纳：基线刷新时刻与尾页拉取精确重合，单独的一元 RPC 只会换来第二次往返、第二个待调和的 seq，以及一个客户端「何时重取」决策——而搭载设计把这个决策整个删掉了。
+
+**不透明的 `get(agent)` 提供方契约**——曾是第一稿，后被否决：计算模型藏在领域内部时，框架永远无法为状态做检查点、无法服务冷会话（没有 agent、没有已加载的日志——`get` 无处可跑）、也无法从日志中段续算。注册 `(init, apply, view)` 单元把驱动权交给框架，领域只留纯数学；有 host 侧行为需求的领域，其服务订阅照旧自持，与投影单元互不牵连。
+
+**为 plan 待定意图专设的仅实时叠加钩子（`live?(agent, base)`）**——不予采纳：它存在的唯一理由是用户的 plan *选择*不在日志里。让选择走标准命令通道后，`command/run` 上了账，待定态成为纯回放量，投影契约保持恰好三个纯函数。
+
+**把 seam 命名为 `registerFold`**——已被单元契约取代：注册对象如今确实是一个折叠，但本仓库里 `fold*` 专指纯 `(events) => state` 辅助函数，而该 seam 注册的是带 key、带 schema、带版本的单元。投影仍是事件溯源中指称读模型角色的术语，#587 的 Note 标题与 #497 的评论也都已在使用它。
+
+**客户端侧折叠（带 `fromEvent` 的按领域投影 cell）**——曾是第二稿，后被否决：一旦 plan 的单元要折叠两种事件，客户端 cell 就必须在浏览器里复刻 host 的状态转移逻辑——同一个折叠写两遍、各自演化。推送成品值（标题帧先例的泛化）保住唯一计算地点，并把客户端简化为一个由 seq 把守的通用值仓；领域零客户端代码。
+
+**对日志尾部的有界反向扫描（absorber 声明）**——暂不采纳：今天没有任何东西需要它，它只服务于「每个事件都携带完整折叠状态」的领域，而持久投影缓存以统一方式覆盖同一冷读需求（缓存行 + 正向尾部回放——与客户端的基线 + 追赶、与分页加载是同一套配方）。只有当出现检查点机制服务不了的真实冷读路径时才重议。
+
+**`invalidate` 式 cell（标脏，遇领域事件就重取）**——不予采纳：它的存在只为伺候增量事件。全量值规则让每个领域都是 last-wins；goal 的重取循环、合并逻辑、陈旧读栅栏随之全部消失。
+
+**把注册表挂到 `ctx.apiProxy` 名下**——不予采纳：会话投影并非 web 专属（TUI、ACP（Agent Client Protocol）、headless 都是未来消费方），且领域包不得依赖 apiproxy 包。独立 seam 还顺带删掉了 #587 从 api-proxy 指向 plan 包的 type-only 导入边。
+
+**独立的客户端 `SessionProjectionViews` 类型表**——不予采纳：一张 `SessionProjectionMap` 端到端贯通正是协议直通纪律（不设第二套 DTO 词汇）；值就是 JSON 载荷，渲染归 slot 管。
+
+**用事件广播收集、替代注册表遍历**——不予采纳：异步监听器给不出那个单一的同步切面，而正是它让 `asOfSeq` 成为横跨所有 key 的一致快照；注册表才是本仓库承接贡献的通行形状（`ctx.tools`、提示词片段、slot）。
+
+**专设 `plan/select` 选择事件（用结构化领域事件替代折叠命令记录）**——不予采纳，改用命令通道：`command/run` 的结构化 `{name, args}` 已经记录了选择，`/plan` 的语法与其折叠逻辑同住一个插件（领域内耦合，非跨领域），还少一种事件类型。处理器必须在任何可能失败的路径之前调用 `set()`，使已入日志的请求与运行面不可能分叉——这是领域内部的顺序约束，文档写在处理器处。
+
+**保留 `setPlanMode` 专用 RPC**——不予采纳：plan 选择就是一条普通的用户命令；命令通道给它持久记录、flow 渲染、多标签页可见性与准入语义，不需要专设协议方法。Web UI 的交互组件（一个开关）在内部拼出命令行即可。
+
+**让变更 RPC 的响应喂 cell 状态**——不予采纳：已提交的 mux 事件即刻到达，携带同一个全量值外加 seq；「响应喂状态」正是当初逼出 #527 写 revision 栅栏的根源。
+
+## Acceptance criteria
+
+- 领域插件把按会话的日志派生状态送达 React，只需写：全量值事件声明、一次 host 侧单元 `register`、自己那份 `SessionProjectionMap` merge、以及 inject 回调——零客户端侧代码，不改客户端 `Session` 类、`ConversationSnapshot`、api-proxy 或任何协议 schema 文件。
+- 历史尾页携带 `projections`，其 `asOfSeq` 等于窗口尾部 seq；loadOlder 页永不携带；未装注册表的部署照常返回不带该块的历史，客户端把所有 key 视为缺席。
+- 陈旧的基线不能覆盖更新的 `session/projection` 帧，重放的帧也不能让值仓倒退（两条路径都做 seq 高者胜测试）。
+- 在一个标签页执行的斜杠命令，刷新后、在第二个标签页上、恢复之后都在 flow 中渲染出持久节点；未注册的命令渲染通用卡片；命令结果的 composer 通知路径彻底移除。
+- `useProjection` 经标准 props 套件抵达组件；没有任何钩子穿过 inject 契约（包括 `useSelection`）。
+- 会话标题搭乘这对通用机制（基线块 + 投影帧）；专设的 `session/title` 帧与客户端标题快照表彻底移除。
+
+## Risks
+
+- **全量值规则是承重结构**：未来某个领域若只记裸增量，就无法凭其最新事件服务消费方，还会让自己的单元复杂化。缓解：该规则写明在本 Note 与投影包的 README 里；单元契约让完整状态在每次转移处都是显式的。
+- **单元的同步纪律**：`init`/`apply`/`view` 一旦 await 就会撕裂一致性切面。注册表在文档中申明这条纪律，invariant 配套在可行范围内断言同步性；其余由评审把关。
+- **注册表的实时增删不做推送**：会话中途加载或卸载领域插件会改变键集，但不会触发任何会话事件、也不会推任何帧；开着的客户端持有陈旧的 key 直到下次尾页拉取（重连、缺口修补、打开）。接受为仅开发期（HMR）的陈旧时窗——日后可以在变更流上加一个注册表变更推送，契约不受影响。
+- **忙碌会话上的正向驱动开销**：每个已提交事件都要过每个已注册单元的 `apply`。按构造，单元的逐事件开销很低（全量值规则），不匹配的事件返回同一引用，且已注册领域的数量很小；若真出现热点路径，可以加按单元的事件类型预过滤，契约不变。
+- **投影载荷膨胀**：每个尾页携带每个已注册的 key。载荷是 UI 量级状态的全量值（一张 todo 清单、一份 goal 快照）；将来若某领域的值很大，可以在请求上加逐 key 的 opt-out 或惰性 key，模型本身不用改。
+- **命令日志体量**：每条斜杠命令两个仅日志事件；上限由人敲命令的频率决定，相对分片体量可忽略不计。
+- **重新对接的返工**：三个未合入的 PR 要变基到挪动后的地基上。这是基础设施先行的既定代价；设计台账中的迁移映射一节逐一列出每个 PR 的保留/删除清单。

+# Agent Note: Storage root placement and derived-medium recovery
+
+Status: proposed
+
+English | [中文](2026-07-28-storage-root-and-derived-medium-recovery.zh.md)
+
+## Problem
+
+The persisted projection cache ([RFC](2026-07-27-session-projection-and-command-log.md), shipped as `dsh-session-projection-cache`) surfaced two gaps in the storage substrate it landed on. Both are properties of the domain-KV stack ([design](2026-07-24-domain-kv-storage-and-workspace.md)), not of the cache itself, and both bite the cache first because it is the first *derived* medium on that stack.
+
+**Where the files actually live.** The shipped Web overlay gives the json backend a relative root — `root: './.storages'` (`apps/cli/config/web.cordis.yml`) — while the shared base defaults the session store to the global harness home (`$DSH_HOME/sessions`, default `~/.dsh/sessions`); no equivalent global root exists for `storage-json`. `JsonStorageBackend` never resolves its root either — each unit open joins the still-relative path against whatever `process.cwd()` is at that moment (packages/storage/storage-json/src/index.ts) — the exact hazard the JSONL session backend resolves-once to prevent ("later process.cwd() changes cannot split one backend across roots", packages/session-persistence/session-persistence-jsonl/src/index.ts). Net effect: session logs are global across launch directories, but `workspace.json` and `session_projcache.json` land under `/.storages/`. Two launches from different directories share their sessions yet see different workspace registries and different projection caches — and the cache exists precisely to serve the cross-session cold listing, which now misses for every session last cached under another launch directory.
+
+**How recovery works today.** Inside a healthy medium the cache is fully self-healing by design: a `stateVersion`-mismatched row is discarded and refolded, a log shrunk below a row's watermark is detected by the anchored restore floor and answered with one full re-read, and every background write is fail-soft. But at the *medium* level there is no recovery at all: a truncated, hand-edited, or version-bumped `session_projcache.json` fails `openJsonUnit` with `malformed-medium`/`version-mismatch` (packages/storage/storage-json/src/format.ts), a schema-drifted record fails domain open with `invalid-record` (packages/storage/storage-domain/src/index.ts), the rejection propagates through `SessionProjectionCache[Service.init]`, and under the CLI's fail-loud boot the assembly refuses to start. A file whose entire content is rebuildable from session logs can brick boot. This contradicts the cache package's own stated stance ("a stale or unreadable cache costs a longer tail replay, never a wrong value") and the cache domain spec's JSDoc ("version bumps discard the whole medium"), which today describes an aspiration, not the implementation. The same fail-loud path is *correct* for `workspace.json` — workspace records are authoritative, not derivable — so the missing concept is a per-domain declaration of authority, not a global behavior change.
+
+## Proposal
+
+Two independent changes, one per gap.
+
+### One global storage root, resolved once
+
+- `AppCLIEntry.composePatches` Source 0 additionally patches `storage-json.root` to `join(resolveDshHome(), 'storages')` — `~/.dsh/storages` by default, beside `~/.dsh/sessions` — and `PROFILE_MAPPINGS` gains `storageRoot` → (`storage-json`, `root`), mirroring `persistenceRoot` exactly. The yml keeps `./.storages` as the raw-composition engineering default (tests and bare Loader boots are unaffected), same layering as the session root today.
+- `JsonStorageBackend` resolves its configured root once at construction (`resolve(config.root)`), adopting the JSONL backend's recorded rationale verbatim: a later `process.cwd()` change must not split one backend across roots. The SQLite storage backend already resolves its path.
+- Pre-release stance applies: no migration shim. A deployment that cached under `/.storages` re-derives everything (workspace re-bootstraps from the header index; the projection cache refolds lazily) or moves the two json files by hand once.
+
+### Declared derived media: reset instead of reject
+
+- `DomainSpec` gains `recovery?: 'reject' | 'reset'` (default `'reject'`). The spec object is already the single source of a domain's identity and layout; whether its medium is authoritative or derived is the same kind of fact and lives in the same place. `session_projcache` declares `'reset'`; `workspace` stays on the default.
+- `KvFacet` gains one primitive: `destroy(descriptor): Promise` — remove the unit's medium entirely (json: delete the file; sqlite: drop the unit's tables). Like `open`, it is a backend storage primitive, not policy.
+- `DomainFacility.open`, when a spec declares `'reset'` and the open fails with exactly a damage-class error — `StorageError('version-mismatch' | 'malformed-medium')` or `DomainError('invalid-record')` — logs one warning naming the domain and the discarded medium, calls `destroy`, and opens again empty. Every other failure (`backend-not-found`, `facet-unsupported`, `already-open`, I/O errors) stays loud regardless of the declaration: misconfiguration and environmental faults are not medium damage. The retry is single-shot — a second failure propagates, so a persistently failing medium cannot loop.
+- With this in place the cache domain spec's version field gains its intended meaning: bumping `version` (or letting zod reject drifted rows) genuinely discards the whole medium and the cache rebuilds through its normal write points and cold reads — the recovery ladder's outermost rung, matching the row-level rungs already shipped.
+
+## Alternatives considered
+
+**Keep per-launch-directory `.storages` (status quo)** — rejected: sessions are global, so every derived-from-sessions medium splits against its own source of truth; the cache's motivating scenario (one listing over all sessions) structurally misses rows, and the workspace registry indexes sessions it cannot see from another launch directory.
+
+**Patch only the projection cache's route to a global root, leave `workspace.json` per-cwd** — rejected: the workspace registry has the identical global-vs-cwd mismatch, and the user decision that shaped the cache placed it deliberately beside `workspace.json` — one hub root keeps the media co-located and the mental model single.
+
+**Cache-plugin-local recovery (catch damage errors in `SessionProjectionCache[Service.init]`, delete the file, reopen)** — rejected: the plugin cannot name the medium path without reaching around the backend abstraction, and every future derived domain would re-implement the same catch; the facility is the one place that already classifies open failures.
+
+**Fall back to an ephemeral in-memory domain on damage** — rejected: it silently degrades to memory-only for the life of the process and the damaged file never heals; the next boot fails the same way.
+
+**Rename the damaged medium aside (`.json.corrupt-`) instead of deleting** — not chosen: a derived medium's damaged bytes have no recovery value (the logs are the source of truth) and the litter accumulates unbounded; delete is the honest operation. Rename-aside remains the right choice if a future *authoritative* domain ever wants reset semantics — which is exactly why `recovery` is per-spec.
+
+**A blanket auto-reset for every domain (no spec field)** — rejected outright: `workspace.json` is authoritative user data; silently resetting it on a version bump would destroy workspaces. Authority is a property of the domain and must be declared by its owner.
+
+## Acceptance criteria
+
+- `dsh` launched from any directory reads and writes the same `$DSH_HOME/storages/*.json` (default `~/.dsh/storages`); the profile key `storageRoot` overrides it; a raw Loader boot of the yml still lands in `./.storages` relative to the boot cwd, resolved once at backend construction.
+- With a truncated, version-bumped, or schema-drifted `session_projcache.json`, the assembly boots clean: one warning names the discarded medium, the file is gone, the cache rebuilds through normal operation, and the cold listing column reappears as sessions are re-checkpointed.
+- The same damage to `workspace.json` still fails boot loudly.
+- Facility tests cover: each damage class resets a `'reset'` domain exactly once; non-damage failures stay loud on a `'reset'` domain; a `'reject'` domain propagates every failure; `destroy` removes the medium on both shipped backends.
+
+## Risks
+
+- **Auto-delete on a misclassified error destroys a healthy file.** Mitigated by the closed damage-class list: reset fires only on the three deterministic parse-time codes; ENOENT is already "empty unit", and every I/O error (EACCES, EIO) propagates loudly. The single-shot retry bounds the blast radius to one delete per open.
+- **Root relocation changes where existing checkouts look.** Accepted under the pre-release stance (backends reject old formats, no external consumers); the note above records the one-time manual move for anyone who cares about a per-cwd `workspace.json`'s content.
+- **`destroy` is a new destructive primitive on the storage seam.** Its only caller is the facility's declared-reset path; the backend contract documents it as facility-owned, and nothing model-facing or user-facing can reach it.

+# Agent Note：存储根目录落点与派生介质恢复
+
+Status: proposed
+
+[English](2026-07-28-storage-root-and-derived-medium-recovery.md) | 中文
+
+## Problem
+
+持久投影缓存（[RFC](2026-07-27-session-projection-and-command-log.md)，已作为 `dsh-session-projection-cache` 落地）暴露了它所依托的存储基座的两个缺口。二者都是 domain-KV 栈（[设计](2026-07-24-domain-kv-storage-and-workspace.md)）的属性而非缓存自身的问题，且都首先咬到缓存——因为它是这条栈上第一个*派生*介质。
+
+**文件到底存在哪。** 出厂 Web overlay 给 json 后端的是相对根目录——`root: './.storages'`（`apps/cli/config/web.cordis.yml`）——而共享 base 将会话存储默认为全局 harness home（`$DSH_HOME/sessions`，默认 `~/.dsh/sessions`）；`storage-json` 没有对应的全局根目录。`JsonStorageBackend` 自己也从不 resolve 根——每次打开 unit 都把仍然相对的路径 join 到当时的 `process.cwd()` 上（packages/storage/storage-json/src/index.ts）——这正是 JSONL 会话后端用「构造时 resolve 一次」防住的那个隐患（"later process.cwd() changes cannot split one backend across roots"，packages/session-persistence/session-persistence-jsonl/src/index.ts）。净效果：会话日志跨启动目录全局共享，但 `workspace.json` 和 `session_projcache.json` 落在 `<启动目录>/.storages/` 下。从两个不同目录启动，会话相同，工作区注册表和投影缓存却各是一份——而缓存存在的意义恰恰是跨会话冷列表，如今凡是上次在别的启动目录下缓存过的会话全部 miss。
+
+**现在是怎么恢复的。** 在健康介质内部，缓存按设计完全自愈：`stateVersion` 不匹配的行被丢弃重折，日志缩短到行水位以下由带锚的 restore floor 检出并以一次全量重读回答，每次后台写都是 fail-soft。但在*介质*层面完全没有恢复：被截断、被手改或版本被 bump 的 `session_projcache.json` 会让 `openJsonUnit` 以 `malformed-medium`/`version-mismatch` 失败（packages/storage/storage-json/src/format.ts），schema 漂移的记录让域 open 以 `invalid-record` 失败（packages/storage/storage-domain/src/index.ts），拒绝一路穿过 `SessionProjectionCache[Service.init]`，在 CLI 的 fail-loud 启动下整个组装拒绝启动。一个内容完全可从会话日志重建的文件能把启动搞死。这与缓存包自己声明的立场（"a stale or unreadable cache costs a longer tail replay, never a wrong value"）和缓存域 spec 的 JSDoc（"version bumps discard the whole medium"）相矛盾——后者今天描述的是愿望而非实现。同一条 fail-loud 路径对 `workspace.json` 却是*正确*的——工作区记录是权威数据，不可派生——所以缺的概念是按域声明权威性，而不是全局改行为。
+
+## Proposal
+
+两个独立改动，一个缺口一个。
+
+### 全局唯一存储根，构造时 resolve 一次
+
+- `AppCLIEntry.composePatches` 的 Source 0 追加把 `storage-json.root` patch 到 `join(resolveDshHome(), 'storages')`——默认 `~/.dsh/storages`，与 `~/.dsh/sessions` 并肩——并且 `PROFILE_MAPPINGS` 增加 `storageRoot` →（`storage-json`，`root`），与 `persistenceRoot` 完全镜像。yml 保留 `./.storages` 作为裸组合的工程默认（测试和裸 Loader 启动不受影响），分层方式与今天的会话根相同。
+- `JsonStorageBackend` 在构造时对配置根 `resolve` 一次，原样采纳 JSONL 后端已记录的理由：后续 `process.cwd()` 变化不得把一个后端劈到多个根下。SQLite 存储后端已经 resolve 其路径。
+- 适用 pre-release 立场：不做迁移垫片。曾在 `/.storages` 下缓存过的部署要么全部重新派生（工作区从 header 索引重新 bootstrap；投影缓存惰性重折），要么手动把两个 json 文件挪一次。
+
+### 声明派生介质：损坏时重置而非拒绝
+
+- `DomainSpec` 增加 `recovery?: 'reject' | 'reset'`（默认 `'reject'`）。spec 对象已经是一个域的身份与布局的单一来源；其介质是权威还是派生属于同类事实，落在同一处。`session_projcache` 声明 `'reset'`；`workspace` 保持默认。
+- `KvFacet` 增加一个原语：`destroy(descriptor): Promise`——整体移除该 unit 的介质（json：删文件；sqlite：drop 该 unit 的表）。与 `open` 一样，它是后端存储原语，不是策略。
+- `DomainFacility.open` 在 spec 声明 `'reset'` 且 open 恰以损坏类错误失败时——`StorageError('version-mismatch' | 'malformed-medium')` 或 `DomainError('invalid-record')`——记一条命名该域和被丢弃介质的警告，调用 `destroy`，再空开一次。其余一切失败（`backend-not-found`、`facet-unsupported`、`already-open`、I/O 错误）无论声明与否都保持大声：配置错误和环境故障不是介质损坏。重试单发——第二次失败原样传播，持续失败的介质不会成环。
+- 有了这个，缓存域 spec 的 version 字段才获得其本意：bump `version`（或让 zod 拒绝漂移行）真正丢弃整个介质，缓存经正常写点和冷读重建——恢复阶梯的最外一档，与已落地的行级各档对齐。
+
+## Alternatives considered
+
+**保持按启动目录的 `.storages`（现状）**——拒绝：会话是全局的，所以每个从会话派生的介质都与自己的真源劈叉；缓存的动机场景（一次列出全部会话）结构性丢行，工作区注册表索引着从另一个启动目录看不见的会话。
+
+**只把投影缓存的 route 指到全局根，`workspace.json` 留在 per-cwd**——拒绝：工作区注册表有一模一样的全局 vs per-cwd 错位，而且塑造缓存的用户决策就是刻意把它放在 `workspace.json` 旁边——一个 hub 根让介质同址、心智模型单一。
+
+**缓存插件本地恢复（在 `SessionProjectionCache[Service.init]` 捕获损坏错误、删文件、重开）**——拒绝：插件不越过后端抽象就叫不出介质路径，且未来每个派生域都要重抄同一段 catch；facility 是唯一已经在分类 open 失败的地方。
+
+**损坏时退到内存态临时域**——拒绝：进程余生静默降级为仅内存，损坏文件永不自愈；下次启动照样失败。
+
+**把损坏介质改名旁置（`.json.corrupt-`）而非删除**——未选：派生介质的损坏字节没有恢复价值（日志才是真源），残骸无界累积；删除才是诚实的操作。若未来某个*权威*域想要重置语义，旁置改名才是对的——这正是 `recovery` 按 spec 声明的理由。

+
+- 从任意目录启动 `dsh` 都读写同一份 `$DSH_HOME/storages/*.json`（默认 `~/.dsh/storages`）；profile 键 `storageRoot` 可覆盖；裸 Loader 启动 yml 仍落在相对启动 cwd 的 `./.storages`,并在后端构造时 resolve 一次。
+- `session_projcache.json` 被截断、版本 bump 或 schema 漂移时，组装干净启动：一条警告命名被丢弃的介质，文件消失，缓存经正常运转重建，冷列表列随会话重新 checkpoint 逐步回归。
+- 同样的损坏发生在 `workspace.json` 上仍大声拒绝启动。
+- facility 测试覆盖：每个损坏类恰好重置一次 `'reset'` 域；非损坏失败在 `'reset'` 域上保持大声；`'reject'` 域传播一切失败；`destroy` 在两个出厂后端上都移除介质。
+
+## Risks
+
+- **错误分类失误导致自动删除健康文件。** 由封闭的损坏类清单缓解：重置只在三个确定性解析期代码上触发；ENOENT 本来就是「空 unit」,一切 I/O 错误（EACCES、EIO）大声传播。单发重试把爆炸半径限定为每次 open 至多一删。
+- **根迁移改变既有 checkout 的查找位置。** 在 pre-release 立场下接受（后端拒绝旧格式、无外部消费者）；上文为在乎 per-cwd `workspace.json` 内容的人记录了一次性手动搬移。
+- **`destroy` 是存储 seam 上新增的破坏性原语。** 唯一调用方是 facility 的声明重置路径；后端契约将其记档为 facility 专属,任何面向模型或面向用户的路径都触不到它。

+# Agent Note: Record last activity in the session index
+
+Status: proposed
+
+English | [中文](2026-07-29-durable-last-activity-index.zh.md)
+
+## Problem
+
+A cold (persisted, unattached) session has no stored answer to "when was this last worked in". `dsh-host-apiproxy`'s `summarizeCold()` therefore approximates it with the log file's mtime where one exists — `locate()` resolves a per-session artifact for JSONL and `undefined` for SQLite, whose cold sessions fall back to `createdAt` — and the web client sorts its session tree by the resulting `updatedAt`. The two backends are wrong in opposite directions: JSONL reads too new, SQLite too old.
+
+mtime answers a different question: when the artifact was last written. Every durable write refreshes it, including writes that are not activity — a truncate-repair of a torn tail, the synthetic closers that balance an interrupted turn, and the [`session/end-seed` boundary](../../implemented/architecture/2026-07-30-session-end-seed-log-boundary.md) a seeded session appends. (A `flush` with nothing pending is not among them: the coordinator returns without reaching the backend.) The visible consequence is stable and wrong in one direction: a session touched without being worked in promotes itself above sessions the user actually worked in afterwards, and each touch re-promotes it. "Touched" is broader than "resumed" — `dsh-host-apiproxy`'s `agentFor()` resumes a cold session on first touch, and `sessions.history` reaches it when the web client merely opens one, so ordinary browsing is enough.
+
+The attached projection has a real fix — `lastActivityTime()` skips boundaries — but it needs the event log, and the cold path deliberately does not read one. Reading the log to compute `updatedAt` would defeat the header-only listing that keeps `list()` scaling with session count rather than log size.
+
+The [boundary change](../../implemented/architecture/2026-07-30-session-end-seed-log-boundary.md) raised the frequency of this defect, because a pickup now writes where nothing was written before; `dsh-host-apiproxy`'s README records it under Known Limitations. It did not introduce the approximation, and removing the approximation is a durable-format decision, which is why it is scoped here rather than there.
+
+## Proposal
+
+Store last-activity time where a listing already reads — the session index — so `summarizeCold()` can serve it without opening the log. The coordinator computes the value, because it sees every append and already owns per-id state; backends persist it. That makes it a new `PersistenceBackend` contract element rather than backend-local bookkeeping, and keeps one definition of "activity" shared with the in-log `lastActivityTime()`.
+
+The two shipped backends have opposite constraints, and the proposal is deliberately asymmetric about them:
+
+- **SQLite** gets a column on `sessions`, written in the same transaction as `appendBatch`, at the cost of a monotonic `SCHEMA_VERSION` bump.
+- **JSONL cannot host a mutable header field.** The header is line 1, written once during materialization, and the log is opened for append forever after; `jsonl.spec.ts` pins that committed bytes are never rewritten. A per-append header field would violate an asserted durability invariant, not merely complicate the writer. A per-session sidecar file is the shape to compare against leaving JSONL approximate.
+
+Three questions must be answered before implementation, and none of them is settled here:
+
+**Which events count as activity?** `lastActivityTime()` answers this for the log by excluding `session/end-seed`. A stored field encodes the rule at write time, where the writer sees one batch rather than the whole log. The two must not drift, or the attached and cold surfaces will disagree about the same session.
+
+**How do pre-field logs behave?** Existing artifacts have no value. Falling back to mtime keeps them at today's accuracy; falling back to `createdAt` is honest but reorders every existing session in the picker and the tree.
+
+**Is a sidecar acceptable for JSONL?** It reintroduces a second file per session that can disagree with the log, which the single-artifact design avoided.
+
+## Alternatives considered
+
+**Read the log on the cold path.** Correct by construction and needs no format change, but it defeats the header-only listing: `list()` would scale with total log size, and the web session tree fans out over every session in the store. This is the option the mtime approximation exists to avoid.
+
+**Keep mtime and exclude boundary writes from it.** Rejected as impossible rather than undesirable: mtime is the filesystem's, not the backend's. Nothing short of restoring the timestamp after every boundary write would preserve it, and that races any concurrent reader and lies about the artifact.
+
+**Write the boundary only when repair occurred.** Would reduce the frequency, and the [boundary note](../../implemented/architecture/2026-07-30-session-end-seed-log-boundary.md) already rejected it: the predicate must hold for an orderly restart too. Trading a correctness invariant for timestamp accuracy is the wrong direction.
+
+**Derive activity from a projection cache.** `session-projection-cache` already folds tails past a watermark, so a last-activity unit would ride existing machinery. Rejected as the primary shape because the cache is an optional composition entry; a listing served only when a cache plugin is mounted makes ordering depend on composition.
+
+## Acceptance criteria
+
+- `SessionSummary.updatedAt` for a cold session equals the same value the attached projection reports for that session, verified by resuming, quitting without a turn, and asserting the order is unchanged across both paths.
+- A resumed-then-abandoned session does not sort above a session worked in afterwards, in the web session tree and the TUI resume picker, pinned by an assembled snapshot rather than unit tests alone.
+- The activity rule has one definition: a test proves the stored field and `lastActivityTime()` agree over a log containing boundaries, closers, and a plain turn.
+- Pre-field artifacts load and list without error under the chosen fallback, with the fallback's ordering consequence asserted.
+- SQLite's `SCHEMA_VERSION` bump rejects the old on-disk version per the repo's no-migration stance.
+
+## Risks
+
+**Two definitions of activity drift.** The stored field is computed per batch, the projection over a whole log. A new event type classified one way at write time and the other at read time yields a session whose cold and attached orderings disagree — a bug that only appears after a restart, which is where it is hardest to notice.
+
+**A JSONL sidecar can disagree with its log.** A crash between the log append and the sidecar write leaves a stale value with no torn-tail marker to repair it. Every consumer would need to treat the sidecar as a hint, which is close to what mtime already is.
+
+**The fallback reorders existing sessions.** Whichever fallback is chosen, users with existing logs see their picker and tree reorder once on upgrade. `createdAt` makes that reordering large.
+
+**Cost may exceed the defect.** The defect is a misordering of abandoned sessions. If the honest answer for JSONL is "keep the approximation", this note's outcome may be documenting that decision rather than implementing a field — and that is an acceptable outcome.

+# Agent Note: 在会话索引中记录最后活动
+
+Status: proposed
+
+[English](2026-07-29-durable-last-activity-index.md) | 中文
+
+## 问题
+
+一个冷会话（已持久化、未附加）对「上次是什么时候在这里面工作过」没有任何已存储的答案。因此 `dsh-host-apiproxy` 的 `summarizeCold()` 在存在日志文件时用它的 mtime 来近似它——`locate()` 为 JSONL 解析出一个逐会话产物，为 SQLite 解析出 `undefined`，而 SQLite 的冷会话会回退到 `createdAt`——而 web 客户端就按由此得到的 `updatedAt` 为自己的会话树排序。这两个后端错的方向正好相反：JSONL 读出来偏新，SQLite 偏旧。
+
+mtime 回答的是另一个问题：这份产物上次是什么时候被写入的。每一次持久写入都会刷新它，包括那些并不是活动的写入：一次对撕裂尾部的截断修复、用来平衡被中断的轮次的那些合成 closer，以及带种子的会话会追加的 [`session/end-seed` 边界](../../implemented/architecture/2026-07-30-session-end-seed-log-boundary.md)。（没有待处理内容的 `flush` 不在其中：协调器在到达后端之前就返回了。）用户可见的后果是稳定的，而且只朝一个方向错：一个被触碰过却没有在里面工作过的会话，会把自己排到用户此后真正工作过的那些会话之前，而且每次触碰都会重新把它排上去一次。「触碰」比「恢复」的范围更宽——`dsh-host-apiproxy` 的 `agentFor()` 会在首次触碰时恢复一个冷会话，而 web 客户端仅仅打开一个会话时 `sessions.history` 就会到达它，因此普通的浏览就够了。
+
+已附加会话的那个投影有真正的修复办法（`lastActivityTime()` 会跳过边界），但它需要事件日志，而冷路径有意不去读日志。为计算 `updatedAt` 而读取日志，会让只读 header 的列举失去意义，而正是它让 `list()` 的开销随会话数量而非日志体量增长。
+
+[边界那次变更](../../implemented/architecture/2026-07-30-session-end-seed-log-boundary.md)提高了这个缺陷的出现频率，因为一次拾起如今会在此前完全无写入的路径上产生写入；`dsh-host-apiproxy` 的 README 已在 Known Limitations 中记录该项。它并没有引入这套近似做法，而移除这套近似是一项持久格式决策，因此它的范围划在本文，而不是那里。
+
+## 提案
+
+把最后活动时间存到列举本就会读取的地方，也就是会话索引，这样 `summarizeCold()` 无需打开日志就能给出答案。该值由协调器计算，因为它看得到每一次追加，而且本就拥有每 id 状态；由后端负责持久化。这样它就成为 `PersistenceBackend` 契约中新增的一个要素，而不是各后端本地的账目，同时让「活动」只保留一个定义，与日志内的 `lastActivityTime()` 共用。
+
+两个已交付的后端受到的约束正好相反，本提案对它们有意采取不对称的处理：
+
+- **SQLite** 在 `sessions` 表上得到一列，与 `appendBatch` 在同一个事务中写入，代价是一次单调的 `SCHEMA_VERSION` 递增。
+- **JSONL 无法承载一个可变的 header 字段。** header 就是第 1 行，在物化时一次写就，此后这份日志永远以追加方式打开；`jsonl.spec.ts` 钉住了「已提交的字节绝不重写」。一个每次追加都要改的 header 字段，违反的是一条被断言的持久性不变式，而不只是让写入方变复杂。要与「让 JSONL 保持近似」相比较的形态，是每会话一个伴随文件。
+
+实现之前必须回答三个问题，本文对它们都没有定论：
+
+**哪些事件算作活动？** 对日志而言，`lastActivityTime()` 通过排除 `session/end-seed` 回答了这个问题。一个已存储字段是在写入时编码这条规则的，而写入方在那里只看到一个批次，不是整份日志。两者不得发生漂移，否则已附加表层与冷表层会对同一个会话给出彼此矛盾的答案。
+
+**该字段引入之前的日志表现如何？** 既有产物里没有这个值。回退到 mtime 能让它们保持今天的准确度；回退到 `createdAt` 是诚实的，但会把选择器和会话树里每一个既有会话都重新排一次序。
+
+**对 JSONL 来说伴随文件可以接受吗？** 它重新引入了每会话第二个文件，而该文件可能与日志不一致，这正是单产物设计所避开的。
+
+## 考虑过的替代方案
+
+**在冷路径上读取日志。** 它按构造就是正确的，也不需要改动格式，但会让只读 header 的列举失去意义：`list()` 的开销将随日志总体量增长，而 web 会话树会扇出到存储中的每一个会话。mtime 近似的存在，正是为了避开这个选项。
+
+**保留 mtime，但把边界的写入排除在它之外。** 否决的理由是做不到，而不是不合意：mtime 属于文件系统，不属于后端。除了在每次边界写入之后把时间戳复原，没有别的办法能保住它，而那样做会与任何并发读取方产生竞态，也会对这份产物撒谎。
+
+**仅在确实发生了修复时才写入边界。** 这能降低出现频率，而[边界 Agent Note](../../implemented/architecture/2026-07-30-session-end-seed-log-boundary.md)已经否决过它：谓词对有序重启同样必须成立。用一条正确性不变式去换时间戳的准确度，方向是错的。
+
+**从投影缓存派生活动时间。** `session-projection-cache` 本就会折叠水位线之后的尾部，因此一个最后活动单元可以搭乘既有机制。它作为主形态被否决，因为该缓存是一个可选的组合项；只有挂载了缓存插件才提供的列举，会让排序取决于如何组合。
+
+## 验收标准
+
+- 冷会话的 `SessionSummary.updatedAt` 等于已附加会话的投影为同一个会话报告的那个值；验证方式是恢复、不跑轮次就退出，并断言两条路径上的顺序都没有变化。
+- 在 web 会话树和 TUI 恢复选择器中，一个恢复后即被弃置的会话不会排到此后工作过的会话之前；由一份组装后的快照钉住，而不是只靠单元测试。
+- 活动规则只有一个定义：一个测试证明，在一份同时包含边界、closer 和一个普通轮次的日志上，已存储字段与 `lastActivityTime()` 的结果一致。
+- 在选定的回退方案下，该字段引入之前的产物能够无错误地加载和列举，并且该回退在排序上的后果有断言覆盖。
+- 按本仓库不做迁移的立场，SQLite 的 `SCHEMA_VERSION` 递增会拒绝旧的磁盘版本。
+
+## 风险
+
+**「活动」的两个定义发生漂移。** 已存储字段按批次计算，而投影在整份日志上计算。一种新事件类型若在写入时按一种方式归类、在读取时按另一种方式归类，就会产生一个冷排序与已附加排序彼此矛盾的会话；这个缺陷只在重启之后才显现，而那正是最难被注意到的地方。
+
+**JSONL 的伴随文件可能与它的日志不一致。** 在日志追加与伴随文件写入之间发生崩溃，会留下一个陈旧的值，而且没有撕裂尾部标记可用来修复它。每个消费方都得把伴随文件当作一条提示来对待，而这与 mtime 今天的地位已经很接近了。
+
+**回退方案会让既有会话重新排序。** 无论选定哪种回退，持有既有日志的用户都会在升级时看到自己的选择器和会话树重新排一次序。选 `createdAt` 会让这次重排的幅度很大。
+
+**代价可能超过这个缺陷本身。** 该缺陷是被弃置会话的排序出错。如果对 JSONL 来说诚实的答案是「保留这套近似」，那么本文的结局可能是记录下这个决定，而不是实现一个字段，而这也是一个可以接受的结局。

+# Agent Note: Record the resume process boundary in the session log
+
+Status: rejected — the boundary belongs at the seeded-`Session` constructor, which also covers fork and replay; superseded by [the end-seed boundary](../../implemented/architecture/2026-07-30-session-end-seed-log-boundary.md)
+
+English | [中文](2026-07-29-session-resumed-log-boundary.zh.md)
+
+## Problem
+
+A session's durable log gave no evidence that it had changed processes. `session/created`, `session/disposed`, and `session/flush` are cordis runtime signals rather than `SessionEventMap` members, and `agent/session-start` carries a `SessionStartSource` but is emit-only and never logged. Reading a stored log therefore gave no hint that anything had been resumed.
+
+That gap makes one class of question unanswerable. A plugin that owns a standalone open/close pair in the log — compaction's `compact/start` … `compact/end` is the only one today — must distinguish an unmatched opening marker left by a process that died mid-operation from one an operation is holding right now. Those two states are **byte-identical in stored history**. Without a boundary the owner has to choose between refusing forever (an unmatched marker wedges the operation permanently, and because automatic compaction failure is warn-and-continue the user-visible result is that compaction silently stops working until the context window overflows) and proceeding always (which defeats the point of holding a lock).
+
+The pressure to fix this is immediate: moving `compact/start` to its real time point, before summarization, widens the crash window from a few microseconds of synchronous appends to the length of a whole model call, so orphaned brackets go from rare to routine.
+
+## Proposal
+
+`@deepseek-ai/dsh-session-persistence` declares one log-only `session/resumed` with an empty payload and appends exactly one at the end of every cold load, in the same `commitRepair` batch as any crash-repair closers and positioned after them — so every event before the boundary has a smaller seq and was written by a writer that is no longer tracking this log. Ownership lands narrowly on `loadCore()`, the cold-load path reached by `load()` and by `adopt()`. `loadLiveSnapshot()` appends nothing, and the non-mutating `inspect()`/`readFrom()` reads never write one.
+
+The predicate a bracket owner evaluates is purely a function of the log: an unmatched opening marker with a `session/resumed` after it is stale, and one with no `session/resumed` after it is live.
+
+`time` is `Date.now()` floored at the log's greatest `time`, deliberately unlike the synthetic closers, which reuse the last real event's timestamp so repair output stays a deterministic function of stored history. The wall clock is not monotonic — an NTP step, a VM restore, or a log copied from a machine that was ahead can put it behind events already stored — so the floor keeps every cross-boundary duration non-negative. The floor is durable, because the clamped boundary is stored and joins the log's maximum: one future-dated event pins every later boundary in that log to the same instant until wall time passes it.
+
+**The predicate distinguishes process succession, not concurrent writers.** `load()`'s liveness guard is `ctx.sessions.get(id)`, which only sees sessions live in *this* runtime, and no backend takes a cross-process per-session lock. So process B cold-loading a session A currently owns writes a boundary after A's still-open bracket. A consumer that must tolerate concurrent writers still needs a liveness signal beyond the log.
+
+## Why this was rejected
+
+Two reasons, found while reviewing where the marker belonged.
+
+**It covers no fork.** `sessions.fork()` and a subagent fork child construct a seeded session without touching persistence, so neither gets a boundary. A forked child inherits its parent's prefix verbatim — including an open `compact/start` the parent is still holding — which is the one case where the inherited bracket's owner is demonstrably alive. The predicate was unavailable exactly where it was most needed.
+
+**Minting the marker at load made a read path a durable write.** Every consequence the review surfaced traced to that: a revision bump on every cold load, a `commitRepair` batch on a balanced log with nothing to repair, the durable time floor above, a load that fails against a read-only store, and a marked log after a resume the caller then cancelled. None of these are wrong given the placement; they are the placement's cost.
+
+The successor keeps the problem statement and the concurrent-writer scope limit unchanged, and moves the write to `Session`'s constructor — the single waist all six seeded-start paths pass through, fork included. Because the marker then rides the ordinary seed-persistence path, the whole durable-write surface above disappears.
+
+## Alternatives considered
+
+**Use `Session.firstLiveSeq` as the staleness predicate.** Dismissed here on the grounds that it is documented as deliberately not persisted, so the same stored log yields different answers in different processes and a read-only reader cannot evaluate it at all. That reasoning was sound about the field and wrong about the conclusion: the fix is to persist a projection of it rather than to compute the boundary somewhere else. This is the alternative that became the successor.
+
+**Declare the event in core (`dsh-session`).** Rejected here because "the constructor cannot distinguish resume from fork or replay." That is true and turned out not to matter — the distinction is not needed, since inherited history is dead history in all three cases.
+
+**Teach `interruptedTurnClosers` to close `compact/*`.** Rejected: `compact/*` is plugin-owned vocabulary and core must not know it. Core closes turn, step, and tool boundaries — the relations it owns. The successor keeps this rejection.
+
+**Lazy self-repair: the owner appends a synthetic closing marker when it finds an orphan.** A write inside a read-shaped check, and it needs an invariant exception for a numbered owner whose turn has already closed.
+
+**A merge-extensible repair-contributor registry in core.** The right shape once a second consumer exists; with one consumer today, `packages/AGENTS.md` says not to split a seam preemptively.
+
+**Write the boundary only when repair actually occurred.** Rejected: the predicate must hold for an orderly restart too, where there is nothing to repair. The successor keeps this rejection.
+
+## Related
+
+The cold-session `updatedAt` skew this proposal documented is scoped in [the last-activity-index Agent Note](../../proposed/architecture/2026-07-29-durable-last-activity-index.md). That defect predates this proposal and survives its rejection: it is caused by mtime counting every durable write, not by any one boundary.

+# Agent Note: 在会话日志中记录恢复的进程边界
+
+Status: rejected — 边界应当落在带种子 `Session` 的构造函数上，那里同时覆盖 fork 与回放；由[种子结束边界](../../implemented/architecture/2026-07-30-session-end-seed-log-boundary.md)取代
+
+[English](2026-07-29-session-resumed-log-boundary.md) | 中文
+
+## Problem
+
+会话的持久日志此前无法证明它换过进程。`session/created`、`session/disposed` 和 `session/flush` 是 cordis 运行时信号，而不是 `SessionEventMap` 成员；`agent/session-start` 虽然携带 `SessionStartSource`，却只用于 emit，从不记录。因此，读取一份已存储日志得不到任何关于「曾经发生过恢复」的线索。
+
+这一空缺让一类问题无法回答。在日志中拥有独立开始／结束事件对的插件必须区分两种未匹配的起始标记：一种由某个在操作中途死亡的进程留下，另一种正被当前某项操作持有；今天符合这一形态的只有压缩的 `compact/start` … `compact/end`。这两种状态**在已存储历史中逐字节相同**。没有边界，所有方只能在两种做法之间选择：永远拒绝（一个未匹配的标记会永久卡住该操作，而自动压缩失败采取警告并继续的策略，因此用户可见的结果是压缩静默停止工作，直到上下文窗口溢出），或者始终继续（这让持有锁失去了意义）。
+
+修复它的压力是即刻的：把 `compact/start` 移到摘要生成之前这个真实的时间点，会把崩溃窗口从几微秒的同步追加扩大为一整次模型调用的时长，孤儿括号也就从罕见变为常态。
+
+## Proposal
+
+`@deepseek-ai/dsh-session-persistence` 声明唯一一个纯日志事件 `session/resumed`，其载荷为空，并在每次冷加载结束时恰好追加一条：与崩溃修复产生的 closers 同处一个 `commitRepair` 批次，且排在它们之后。因此，该边界之前的每个事件都有更小的 seq，并且都是由一个不再追踪这份日志的写入方写下的。所有权狭窄地落在 `loadCore()`，也就是 `load()` 与 `adopt()` 到达的冷加载路径。`loadLiveSnapshot()` 不追加任何内容，非变更性的 `inspect()`／`readFrom()` 读取也从不写入。
+
+括号所有方求值的谓词纯粹是日志的函数：未匹配的起始标记之后有 `session/resumed` 的就是陈旧的，之后没有的就是存活的。
+
+`time` 取 `Date.now()` 并以日志的最大 `time` 为下限，刻意区别于合成 closers——后者复用最后一个真实事件的时间戳，以便修复输出始终是已存储历史的确定性函数。挂钟并非单调：一次 NTP 跳变、一次虚拟机恢复，或一份从走快的机器上拷来的日志，都可能让它落在已存储事件之后，因此这个下限让跨边界的时长都非负。该下限是持久的，因为被钳制的边界本身会被存储并加入日志的最大值：一个未来时间的事件会把该日志中之后的每个边界都钉在同一时刻，直到挂钟时间越过它。
+
+**该谓词区分的是进程接替，不是并发写入方。** `load()` 的存活性守卫是 `ctx.sessions.get(id)`，它只看到*本*运行时中存活的会话，而且没有任何后端会取跨进程的按会话锁。因此，进程 B 冷加载一个 A 当前拥有的会话时，会在 A 仍然开放的括号之后写入一个边界。必须容忍并发写入方的消费方仍然需要日志之外的存活信号。
+
+## 为什么被否决
+
+两个原因，都是在复审标记应当落在何处时发现的。
+
+**它完全覆盖不到 fork。** `sessions.fork()` 与子代理 fork 子会话在不触及持久化的情况下构造带种子会话，因此两者都拿不到边界。fork 子会话会逐字节继承父会话的前缀——包括父会话仍然持有的开放 `compact/start`——而这恰恰是继承括号的所有方明显还活着的唯一情形。谓词偏偏在最需要它的地方不可用。
+
+**在加载时铸造标记，把读取路径变成了持久写入。** 复审暴露出的每一项后果都源于此：每次冷加载都递增 revision、对一份无需修复的平衡日志也要走 `commitRepair`、上文那个持久时间下限、加载在只读存储上会失败，以及调用方随后取消的恢复也已留下标记。这些在该放置方式下都不算错，它们就是该放置方式的成本。
+
+取代方案保留问题陈述与并发写入方的适用范围限制不变，并把写入移到 `Session` 的构造函数——全部六条带种子启动路径（含 fork）必经的唯一收窄处。由于标记随后走普通的种子持久化路径，上述整个持久写入面就消失了。
+
+## Alternatives considered
+
+**用 `Session.firstLiveSeq` 作为陈旧性谓词。** 此处以「文档明确它有意不做持久化，因此同一份已存储日志在不同进程中会给出不同答案，而只读读取方根本无法对它求值」为理由否决。这个推理对字段本身是成立的，但结论错了：正确的修法是持久化它的一个投影，而不是把边界挪到别处去算。这条替代方案正是后来的取代方案。
+
+**在核心（`dsh-session`）中声明该事件。** 此处以「构造函数无法把恢复与 fork 或回放区分开」为理由否决。这句话是对的，但事实证明它无关紧要——并不需要这种区分，因为在这三种情形下继承历史都是死历史。
+
+**教 `interruptedTurnClosers` 关闭 `compact/*`。** 否决：`compact/*` 是插件所属词汇，核心不得知道它。核心只关闭轮次、步骤和工具边界，也就是它自己拥有的关系。取代方案保留这条否决。
+
+**惰性自修复：所有方发现孤儿时自行追加一条合成的关闭标记。** 这是在一次形似读取的检查中执行写入，而且需要为一个带轮次编号、其轮次却已经关闭的所有方开一个不变式例外。
+
+**在核心中建一个可合并扩展的修复贡献方注册表。** 一旦出现第二个消费方，这就是正确的形状；今天只有一个消费方，而 `packages/AGENTS.md` 要求不要预先拆分 seam。
+
+**仅在确实发生了修复时才写入边界。** 否决：该谓词对有序重启同样必须成立，而那时没有任何东西需要修复。取代方案保留这条否决。
+
+## 相关
+
+本提案记录过的冷会话 `updatedAt` 偏斜，范围界定在[最后活动索引 Agent Note](../../proposed/architecture/2026-07-29-durable-last-activity-index.md)。该缺陷早于本提案存在，并且在本提案被否决后依然存在：它的成因是 mtime 会计入每一次持久写入，而不是某一个边界。

 ## Conventions
 
 - Every npm package is `@deepseek-ai/dsh-`; vendored packages keep upstream names and are `private: true`. `cordis` is a peerDependency (+ dev) of every harness package.
-- ESM everywhere (`"type": "module"`). Cross-package imports use package names; in-package relative imports include `.ts`. CI subprocesses that boot examples or Cordis configs run built `lib/` under plain Node; only explicit source-path regressions use tsx ([testing policy](docs/testing.md#test-subprocess-launch-modes)).
+- ESM everywhere (`"type": "module"`). Cross-package imports use package names; in-package relative imports include `.ts`. Config subprocesses run built `lib/` under plain Node; source regressions use their declared launcher ([testing policy](docs/testing.md#test-subprocess-launch-modes)). The `dsh` CLI source launch runs through tsx's ESM-only hook (`node --import tsx/esm`); modules it reaches must stay ESM (no CJS-only shapes) — Node's native TypeScript modes are unavailable across the engines range ([source-launch contract](.agents/notes/implemented/architecture/2026-07-29-dsh-source-launch-tsx-esm.md)). TUI/Web `cordis.yml` bare plugins must appear in their resolver manifest's `dependencies`; `verify-cordis-config` enforces it.
 - **Registrations are effects**: every contribution goes through `ctx.effect()` / `ctx.on()`; a registry's `register()` returns the disposer.
 - **Runtime invariants assert owned relationships.** Check authoritative event streams or mutable data, not service or method presence, plugin metadata or effects, or fixed pure examples. If a package has no plausible relationship, an explained empty companion is correct ([package contract](packages/AGENTS.md)).
 - **Typed events use declaration merging** and merge-extensible maps. Event JSDoc needs `@mode` and payload `@param`; scoped keys absent from payloads need `@dshScopeScan unsupported`. Public service methods document parameters and non-void returns.

 - **Testing policy** — [docs/testing.md](docs/testing.md). Every non-trivial model- or product-user-visible behavior change adds or updates a keyless snapshot through a real runnable example in the same PR; package tests, e2e-only assertions, and mock-only fixtures do not substitute for the assembled application transcript. Fixtures must replay on macOS/Linux; fix fixtures, not normalizers.
 - **A tool's UI render intent is part of its design**, decided up front (`generic`/`terminal`/`diff`, `locations`); presentation methods are pure functions of `args` ([cookbook](docs/cookbook/adding-a-tool.md)).

-The `dsh` command-line entry follows the `apps/` assembly tier: `apps/*` are product assemblies over `packages/*` libraries. Plain `dsh` boots the interactive TUI coding agent, `dsh -p "task"` runs one headless turn, and `dsh web` serves the browser UI.
 
-Argv is parsed once through a [Commander](https://github.com/tj/commander.js) adapter ([`src/args.ts`](src/args.ts)): one program whose default (no subcommand) is the TUI/headless surface (`--config`, `-p`/`--prompt`, `--resume`) and whose `web` subcommand is the browser UI. `src/bin.ts` switches on the resolved mode and dynamic-imports only that mode's module. `dsh --help` lists every mode and `dsh web --help` renders the web usage, `dsh --version` prints this app's version, and an unknown option or a mistyped `--resume` fails loud (stderr, exit 1) instead of misrouting. `dsh web`'s `--host`/`--port` are unvalidated pass-through overrides: the `dsh-host-webserver` schema is the single source of both the default (the shipped `cordis.yml` value when a flag is absent) and validity, and rejects a bad value at boot.
+Argv is parsed once through a [Commander](https://github.com/tj/commander.js) adapter ([`src/args.ts`](src/args.ts)): one program whose default (no subcommand) is the TUI/headless surface (`--config`, `-p`/`--prompt`, `--resume`), whose `meta` subcommand is the same TUI over this checkout, whose `upgrade` subcommand is an option-less guided-session entry, and whose `web` subcommand is the browser UI. `src/bin.ts` switches on the resolved mode and dynamic-imports only that mode's module. `dsh --help` lists every mode and `dsh web --help` renders the web usage, `dsh --version` prints this app's version, and an unknown option or a mistyped `--resume` fails loud (stderr, exit 1) instead of misrouting. Every subcommand that shares no option with the default surface — `upgrade`, `web`, `meta` — rejects a leaked `--config`/`-p`/`--resume` rather than running and dropping it. `dsh web`'s `--host`/`--port` are unvalidated pass-through overrides: the `dsh-host-webserver` schema is the single source of both the default (the shipped Web overlay value when a flag is absent) and validity, and rejects a bad value at boot. `--trusted-host` appends named authorities for the /api browser-trust fence; an all-interfaces bind additionally derives the machine's LAN IP literals itself ([`src/app-cli-entry.ts`](src/app-cli-entry.ts)), so the printed LAN URL works without flags.
 
 The TUI surface:
 
-- boots the shipped default config (`examples/tui-agent/cordis.yml`), or the tree named by `--config ` (the demo/test escape for booting an alternate example tree), through [`dsh-app-boot`](../../packages/ui/app-boot/README.md);
-- resumes a persisted session with `dsh --resume ` and, when the Node host exposes `process.execve`, supplies the TUI's in-place handoff host: after selector preflight and current-session flush, the host disposes the app and replaces the process with a normalized `dsh --resume `; runtimes without process replacement keep the displayed command fallback. The flag provides the id on the boot context under `RESUME_SESSION_ID_KEY` (no environment variable), which the shipped config reads through `!!js`, and a missing or unreadable id fails loud instead of creating a fresh session;
-- treats the **invoking directory** as the workspace — sessions, relative paths, and workspace instructions resolve from the cwd;
+- boots `base.cordis.yml` plus `tui.cordis.yml` through [`dsh-app-boot`](../../packages/ui/app-boot/README.md); `--config ` applies a patch-list overlay instead of the personal overlay, while `--config-replace ` boots that file as the complete tree;
+- resumes a persisted session with `dsh --resume ` and, when the Node host exposes `process.execve`, supplies the TUI's in-place handoff host: after selector preflight and current-session flush, the host disposes the app and replaces the process with a normalized resume invocation; runtimes without process replacement leave the session running and say so. This CLI owns session identity and the exit line rather than the config: it mints or selects the `main` session id and provides it, plus the exact command that reproduces this invocation, on the boot context ([`MAIN_SESSION_ID_KEY`](../../packages/ui/tui/README.md) and `TUI_GOODBYE_MESSAGE_KEY`). No `cordis.yml` key can drop resume, and a missing or unreadable id fails loud instead of creating a fresh session;
+- treats the **invoking directory** as the workspace — sessions, relative paths, and workspace instructions resolve from the cwd (`dsh meta` is the sole exception, below);
 - tells the agent where its own source lives: after boot it adds a prompt section naming this harness checkout, resolved from the launcher's real path so it holds under a PATH symlink and an arbitrary cwd, so the self-referential `cordis` toolset can read and modify it;
 - applies the personal overlay from `~/.dsh` (see [app-boot's Personal config](../../packages/ui/app-boot/README.md#personal-config)): `.env` fills environment gaps (ambient > project `.env` > personal `.env`), `config.yaml` patches the booted tree.
 
-The Web and headless surfaces boot one shared composition (`cordis.yml`): both treat the invoking directory as the default project and Workspace root, create named Workspaces beneath that root unless `--workspace-root ` overrides it, load applicable `AGENTS.md`/`CLAUDE.md` instructions into each agent-loop request prefix with a 65,536-byte render budget, and opt into first-message model titles. Headless differs only in listening on an OS-assigned port (parallel `dsh -p` runs never collide; the stderr-printed URL opens the live session in a browser). Both need the frontend dist and client bundles built (`pnpm run build && pnpm run build:web`).
+`dsh meta` is that same TUI with this harness checkout as the workspace, so working on dsh itself needs no `cd`. It chdirs to the checkout root — resolved from the launcher's real path, the same root the source-path prompt section names — after both `.env` layers are loaded, so environment precedence is unchanged while the session cwd and HMR watch root move together. Meta always starts a fresh session and accepts no default-surface options; use ordinary `dsh --resume ` to resume a persisted session.
+
+`dsh upgrade` is a guided fresh-session entry over the default TUI surface: it mints a fresh session in the invoking directory and seeds its first turn with the bundled `dsh-upgrade` skill, exactly as if the user typed `/skill:`. The launcher passes the skill name on the boot context ([`INITIAL_SKILL_KEY`](../../packages/ui/tui/README.md)), which the TUI auto-invokes once the chat is live. Both take no options — `--config`, `-p`, and `--resume` fail loud — and seed only on this first launch, so a later `dsh --resume ` of the session is an ordinary TUI session with no re-injection.
+
+
+The Web and headless surfaces boot `base.cordis.yml` plus `web.cordis.yml`, then apply `$DSH_HOME/config.yaml`; an explicit `--config ` replaces that personal overlay. Both surfaces otherwise share the same composition: both treat the invoking directory as the default project and Workspace root, create named Workspaces beneath that root unless `--workspace-root ` overrides it, load applicable `AGENTS.md`/`CLAUDE.md` instructions into each agent-loop request prefix with a 65,536-byte render budget, and opt into first-message model titles. Headless differs only in listening on an OS-assigned port (parallel `dsh -p` runs never collide; the stderr-printed URL opens the live session in a browser). Both need the frontend dist and client bundles built (`pnpm run build && pnpm run build:web`).
+
+The shipped TUI and Web compositions register the native DeepSeek adapter plus pi-ai OpenAI and Anthropic profiles. Credentials and endpoint overrides come from the provider-standard `DEEPSEEK_API_KEY` / `DEEPSEEK_BASE_URL`, `OPENAI_API_KEY` / `OPENAI_BASE_URL`, and `ANTHROPIC_API_KEY` / `ANTHROPIC_BASE_URL` pairs in the boot's layered environment.
 
 `DSH_TOOLS_MODE` selects the tool presentation mode for the whole Web/headless process: `native` (the schema default when unset), `code` (the `run_code`-only Code Mode wire), or `both`; any other value fails loud at boot through the `dsh-tools` config schema. It is a TEMPORARY seam — process-wide because Loader composition is static — and is removed once the web UI owns per-session tool-mode selection; the TUI surface ignores it (its config tree pins its own mode).

+Source launches run `apps/cli/src/bin.ts` through tsx's ESM-only hook (`node --import tsx/esm`), which transforms TypeScript and projects the root tsconfig `paths` map into module resolution. Node's native TypeScript modes are not used: Node 26 removed `--experimental-transform-types`, and strip-only mode rejects syntax the source graph relies on (vendored parameter properties, decorators, runtime enums/namespaces). The CJS hook stays off because the source graph is ESM-only and the CJS resolver adds ~0.4s of startup. `bin/dsh` pins `TSX_TSCONFIG_PATH` to the checkout's root tsconfig so resolution is cwd-independent, and the `dsh-source-launch-smoke` node-compat gate runs this exact launch vector on every supported Node line. tsx applies the `paths` map without checking dependency declarations, so declaration completeness rests on the static gates: the TUI configs resolve bare plugins through `examples/package.json`, the Web/headless `cordis.yml` through this package's `dependencies`, and `verify-cordis-config` requires every configured bare plugin to be declared, while allowing unrelated dependencies.

 `pnpm run dsh` runs the same entry from the repo root and forwards arguments directly, for example `pnpm run dsh -p "task"`. The built form (`lib/bin.js`, via `pnpm run build`) boots the same config under plain Node.

 TUI 界面：
 
-- 启动已交付的默认配置（`examples/tui-agent/cordis.yml`），或由 `--config ` 指定的树（演示／测试用于启动其他示例树的逃生口），并通过 [`dsh-app-boot`](../../packages/ui/app-boot/README.md) 完成启动；
-- 使用 `dsh --resume ` 恢复已持久化会话。当 Node 宿主公开 `process.execve` 时，还会提供 TUI 的原地移交宿主：选择器预检并刷新当前会话后，宿主会释放应用，并以规范化的 `dsh --resume ` 替换进程；不支持进程替换的运行时保留屏幕上显示的命令回退。该标志通过 `RESUME_SESSION_ID_KEY` 在启动上下文中提供 id（不使用环境变量），已交付的配置通过 `!!js` 读取它；缺失或无法读取的 id 会明确报错，而不会创建新会话；
-- 将 **调用目录** 视为 workspace：会话、相对路径和 workspace 指令都从 cwd 解析；

+- 将 **调用目录** 视为 workspace：会话、相对路径和 workspace 指令都从 cwd 解析（`dsh meta` 是唯一例外，见下文）；
 - 告知 agent 自身源码所在位置：启动后添加一个命名此 harness checkout 的提示词段。该路径从启动器的真实路径解析，因此在 PATH 符号链接和任意 cwd 下仍然有效，使自指的 `cordis` 工具集可以读取并修改它；
 - 应用 `~/.dsh` 中的个人覆盖（参见 [app-boot 的个人配置](../../packages/ui/app-boot/README.md#personal-config)）：`.env` 填补环境缺口（环境中已有的值 > 项目 `.env` > 个人 `.env`），`config.yaml` 则修补已启动的树。
 
-Web 和无头界面启动同一个共享组合（`cordis.yml`）：两者都将调用目录视为默认项目和 Workspace 根目录，除非通过 `--workspace-root ` 覆盖，否则会在该根目录下创建具名 Workspace；它们会把适用的 `AGENTS.md`/`CLAUDE.md` 指令加载到每个 agent-loop 请求前缀中，渲染预算为 65,536 字节，并选用首条消息模型标题。无头界面唯一的差异是监听操作系统分配的端口（并行 `dsh -p` 运行绝不冲突；stderr 打印的 URL 会在浏览器中打开实时会话）。两者都需要先构建前端 dist 和客户端 bundle（`pnpm run build && pnpm run build:web`）。
+`dsh meta` 是以本 harness checkout 为 workspace 的同一个 TUI，因此开发 dsh 自身无需 `cd`。它在两层 `.env` 都加载之后才 chdir 到 checkout 根目录（从启动器的真实路径解析，与源码路径提示词段所指的根目录相同），因此环境优先级不变，而会话 cwd 与 HMR 监视根目录会一并移动。Meta 始终创建新会话，不接受默认界面的任何选项；恢复已持久化会话应使用普通的 `dsh --resume `。
+
+`dsh upgrade` 是默认 TUI 界面之上的引导式全新会话入口：它在调用目录中创建一个全新会话，并以内置 `dsh-upgrade` skill 播种其首轮，效果等同于用户手动键入 `/skill:`。启动器将 skill 名称提供到启动上下文（[`INITIAL_SKILL_KEY`](../../packages/ui/tui/README.md)），TUI 在聊天就绪后自动调用它。两者都不接受任何选项——`--config`、`-p`、`--resume` 都会明确报错——且仅在首次启动时播种，因此之后 `dsh --resume ` 恢复该会话时是普通 TUI 会话，不会重复注入。

+Web 和无头界面启动 `base.cordis.yml` 与 `web.cordis.yml`，随后应用 `$DSH_HOME/config.yaml`；显式的 `--config ` 会替代该个人覆盖。除此之外，两者共享同一套组合：两者都将调用目录视为默认项目和 Workspace 根目录，除非通过 `--workspace-root ` 覆盖，否则会在该根目录下创建具名 Workspace；它们会把适用的 `AGENTS.md`/`CLAUDE.md` 指令加载到每个 agent-loop 请求前缀中，渲染预算为 65,536 字节，并选用首条消息模型标题。无头界面唯一的差异是监听操作系统分配的端口（并行 `dsh -p` 运行绝不冲突；stderr 打印的 URL 会在浏览器中打开实时会话）。两者都需要先构建前端 dist 和客户端 bundle（`pnpm run build && pnpm run build:web`）。

 `DSH_TOOLS_MODE` 为整个 Web／无头进程选择工具呈现模式：可选值为 `native`（未设置时的 schema 默认值）、`code`（仅含 `run_code` 的 Code Mode 协议接口）或 `both`；任何其他值都会经由 `dsh-tools` 配置 schema 在启动时明确报错。它是一个临时 seam：Loader 组合是静态的，因此该设置作用于整个进程；待 Web UI 负责逐会话工具模式选择后便会移除。TUI 界面会忽略该变量（其配置树固定了自身模式）。

+          You are in plan mode. Stay in plan mode until exit_plan_mode succeeds or the user switches the session mode. Imperative language to implement changes means plan the implementation, not execute it. A user's conversational agreement — including an answer confirming something you asked — approves nothing and does not end plan mode; fold the confirmed decision into the plan and submit it through exit_plan_mode.
+
+          Explore first. Use non-mutating reads, searches, static analysis, and checks to ground the plan in the actual repository. Do not edit or write files, change configuration, run formatters or code generation that rewrites tracked files, commit, or otherwise carry out the plan. Prefer existing functions and patterns over new machinery.
+
+          The tool catalog stays the same across modes for request-cache stability. These plan-mode rules override any later tool description or guidance that suggests using mutation tools; those tools remain listed only to keep the request shape stable. Do not use todo_write to track this planning phase: it tracks implementation after an approved plan, while the plan itself belongs in exit_plan_mode.
+
+          Resolve discoverable facts by inspection. Use ask_user_question only for user-owned choices or material ambiguity that inspection cannot answer. Do not ask the user where code lives or how current behavior works when you can find out.
+
+          Make the plan decision-complete: state the goal and success criteria; group implementation changes by subsystem; identify public API, schema, and data-flow changes; cover edge cases, failure modes, tests, acceptance criteria, and explicit assumptions. Keep it concise enough to review but detailed enough that another engineer can implement it without making design decisions.
+
+          When ready, call exit_plan_mode with the complete plan markdown, starting with a # title. Make exit_plan_mode the only and final tool call in that assistant response: it presents the plan for approval, and implementation begins only in a later step after approval. Do not paste the final plan as a plain reply or ask "should I proceed?" through prose or ask_user_question. If review rejects it, incorporate the feedback and present again. If the review channel is unavailable or aborted, stay in plan mode and ask the user to switch modes manually; do not proceed with implementation.

-    section: |
-          You are in plan mode. Stay in plan mode until exit_plan_mode succeeds or the user switches the session mode. Imperative language to implement changes means plan the implementation, not execute it. A user's conversational agreement — including an answer confirming something you asked — approves nothing and does not end plan mode; fold the confirmed decision into the plan and submit it through exit_plan_mode.
-
-          Explore first. Use non-mutating reads, searches, static analysis, and checks to ground the plan in the actual repository. Do not edit or write files, change configuration, run formatters or code generation that rewrites tracked files, commit, or otherwise carry out the plan. Prefer existing functions and patterns over new machinery.
-
-          The tool catalog stays the same across modes for request-cache stability. These plan-mode rules override any later tool description or guidance that suggests using mutation tools; those tools remain listed only to keep the request shape stable. Do not use todo_write to track this planning phase: it tracks implementation after an approved plan, while the plan itself belongs in exit_plan_mode.
-
-          Resolve discoverable facts by inspection. Use ask_user_question only for user-owned choices or material ambiguity that inspection cannot answer. Do not ask the user where code lives or how current behavior works when you can find out.
-
-          Make the plan decision-complete: state the goal and success criteria; group implementation changes by subsystem; identify public API, schema, and data-flow changes; cover edge cases, failure modes, tests, acceptance criteria, and explicit assumptions. Keep it concise enough to review but detailed enough that another engineer can implement it without making design decisions.
-
-          When ready, call exit_plan_mode with the complete plan markdown, starting with a # title. Make exit_plan_mode the only and final tool call in that assistant response: it presents the plan for approval, and implementation begins only in a later step after approval. Do not paste the final plan as a plain reply or ask "should I proceed?" through prose or ask_user_question. If review rejects it, incorporate the feedback and present again. If the review channel is unavailable or aborted, stay in plan mode and ask the user to switch modes manually; do not proceed with implementation.

+// Web e2e scenario: the sidebar session list's scrollbar as the browser
+// actually lays it out — the observable half of the themed-scrollbar change
+// (packages/client/ui-theme/src/styles/scrollbar.css plus the
+// `scrollbar-gutter: stable` reservation on WorkspaceBrowser's `.list`). The
+// ui-theme/ui-workspace unit specs read the CSS text; only a real engine
+// reports the reserved gutter width and the substituted `scrollbar-color`, so
+// those two facts live here.
+//
+// Zero model calls: the list only has to overflow, so the scenario seeds many
+// cold sessions from another spec's committed fixture (seeded-history's
+// seed.jsonl, reused read-only — this spec needs row count, not new recorded
+// content) and never launches a replay row. A stray stream would fail loud
+// with NO_ADAPTER.
+//
+// Headless-chromium caveats, load-bearing for what is asserted below.
+//
+// Headless chromium defaults to an OVERLAY scrollbar: one drawn on top of the
+// content, consuming no layout width unless something reserves space. That is
+// the mode in which the reported symptom exists at all, so this environment
+// reproduces it rather than merely approximating it — measured against clean
+// master, where the list's band is 0 and the bar covers 7px of the relative
+// time. (Under a classic space-consuming bar, `clientWidth` already excludes
+// the bar and nothing can be covered; a headed run under xvfb behaves that way
+// and cannot show the symptom.)
+//
+// The consequence for assertions: comparing the time element's right edge
+// against the list's CLIENT-area right edge holds in both states and proves
+// nothing, because with an overlay bar the client edge is the border edge. The
+// two signals that do separate the states are the reserved band width and
+// `timeCoveredBy`, which measures the overlap against the bar's own width.
+//
+// Both the `scrollbar-gutter: stable` reservation and the sheet's
+// `::-webkit-scrollbar` width are needed for that band, and neither suffices:
+// measured on the running app, deleting either one takes the band from 8 to 0
+// while the other stays in force. The gutter states that space be reserved; the
+// pseudo-element width is what makes chromium treat the bar as occupying layout
+// space in the first place.
+//
+// That conjunction is why `band` and `timeCoveredBy` are both asserted and
+// neither replaces the other. Removing only the gutter leaves `timeCoveredBy` at
+// 0, because the bar is then 8px wide and the row's right padding is also 8px,
+// so it abuts the timestamp without covering it; `band` catches that case.
+// Removing both — the actual master state — is what produces the reported
+// overlap, and `timeCoveredBy` measures it at 7. Each was mutation-checked with
+// the other assertions in its test silenced.
+//
+// Chromium also takes the `::-webkit-scrollbar*` path, not the standard
+// properties: scrollbar.css gates `scrollbar-width`/`scrollbar-color` behind
+// `@supports not selector(::-webkit-scrollbar)`, which is false here. The
+// resolved standard properties therefore read `auto`, and that reading is
+// asserted — a concrete value would mean the gate leaked and silenced the
+// pseudo-element rules. What the theme test measures instead is the pair the
+// pseudo-element rules read: the indirection variables as they resolve ON the
+// list, plus the `::-webkit-scrollbar-thumb:hover` declaration as it stands in
+// the cascade. The hover thumb colour is not observable any other way —
+// chromium folds the `:hover` rule into `getComputedStyle(el,
+// '::-webkit-scrollbar-thumb')`, so that query reports the hover colour at
+// rest and cannot pin either state (measured by deleting the hover rule live:
+// the same query flipped from the hover colour to the resting one).

+## `ctx.sessionProjectionCache` — `SessionProjectionCache`
+
+The persisted projection cache service. Opens the `session_projcache` domain at init, checkpoints live sessions on a throttled write-behind (count/interval triggers from Config) plus two mandatory points — `turn/end` and session disposal (the live-to-cold moment) — and serves the cold-read ladder: cached row, persistence `readFrom` tail, registry `restore`, durable write-back. Every durable write is fail-soft: failures log a warning and the cache self-heals on the next write or cold read.
+
+```ts cordis-catalog
+/**
+ * The zero-I/O listing read: whole values viewed straight from the stored
+ * rows (version-matching keys only), each cut carried with its watermark

+## `ctx.sessionProjections` — `SessionProjectionRegistry`
+
+`ctx.sessionProjections`: the projection unit table and its drive. The service subscribes to `session/event` once; every committed event passes every registered unit's `apply` (eager drive), and a changed state reference notifies the change feed with the schema-validated view. Cells build lazily — a unit registered after events flowed, or a session older than the registry, folds `init` over the in-memory log on first touch (event or read). Registration is an effect (disposer rides the calling fiber): an unloaded domain plugin's key disappears from snapshots and clients read it as capability absence. Duplicate keys throw. Domain plugins register under `ctx.inject(['sessionProjections'], …)` so headless assemblies without the registry stay unaffected.
+
+```ts cordis-catalog
+/**
+ * Register one domain's unit. The registration is an effect on the calling
+ * context's fiber: disposing the fiber (or calling the returned disposer)

 The cause is a TypeScript-enforced same-process input. An active `TurnCancellation` holder copies its discriminant into the runtime-only `AbortSignal.reason` and is retired before `turn/end` publication; the frozen `AbortSignal.reason` remains readable after that retirement. Only the loop reads the cause (`user`, `parent`, or lifecycle-only `disposed`) back off its own machine-private signal at settlement — there is no public reader, and a signal grants cooperating listeners no classification authority. Durable `turn/end` retains the coarse `{ kind: 'aborted' }` outcome; request provenance would require a separate durable event rather than overloading the terminal result.

Merge-extensible event relations belong to the plugin that declares them, so core does not reject an unknown event merely because no turn is open. See [the standalone-event decision](../../.agents/notes/implemented/simplification/2026-07-28-remove-synthetic-log-only-turns.md).
 
+## The end-seed boundary: `session/end-seed`
+
+A seeded session — resume, fork, or replay — appends this log-only event immediately after its constructor seed, as its first live write. Events before it have smaller seq values and came from the seed. It is the durable projection of `firstLiveSeq`: that field answers where this lifecycle's writes start for a consumer holding the object, while the event answers the same question for one holding only stored bytes. The payload is empty, so position and `time` carry the whole meaning, and it produces no message. `Session`'s constructor is the only legitimate writer.
+
+An empty seed writes nothing, and a seed already ending in `session/end-seed` is not re-marked, so reopening an untouched session does not grow its log per pickup. Locate the LAST `session/end-seed` in stored history rather than assuming one exists at `firstLiveSeq`: after a pickup with no work, the event has a smaller seq than the next lifecycle's `firstLiveSeq`.
+
+It exists because seed history and live work are otherwise byte-identical, which defeats any plugin owning a standalone open/close bracket: an unmatched `compact/start` reads the same whether the writer crashed mid-compaction or is compacting right now. An opening marker before `session/end-seed` came from the constructor seed and belongs to an ended lifecycle, whatever ended it (a crash, a succeeding process, or a fork out of a still-running parent), so its owner may treat it as dead. That covers only brackets *this* session inherited: a concurrently live session holding an open bracket over the same history has its own boundary elsewhere, so tolerating concurrent writers needs a liveness signal beyond the log. Core writes the boundary and reads nothing from it — a bracket's vocabulary stays with its owning plugin, which is why crash repair closes turn/step/tool boundaries and never `compact/*`.
+
+Activity ordering excludes the boundary through `lastActivityTime(events)`: picking a session up is not work, and lazy resume means browsing writes one, so a resume picker or session list ordering by log tail would float every opened session to the top.
+
 ## Plugin-contributed log-only events
 
 A plugin may declaration-merge extra `SessionEventMap` types. These are **log-only**: NOT `SurfaceEventType`s (they carry no `surfaceOp` and contribute nothing to derived history). Their owner decides whether they belong to an open execution turn or may stand between turns, and enforces any relation in its own invariant companion. The full per-event enumeration — core and plugin-contributed alike, with payloads and provenance — is the generated [persistence log event catalog](../persistence-catalog.md); the compaction seam's `compact/*` semantics are discussed on [compaction.md](compaction.md).

 Skill lookup is cwd-sensitive because providers may expose workspace-local skills, and its optional signal cancels provider work for the caller. Providers receive the same readonly options object used for cache identity and loading. Cancellation is checked before and after catalog selection, including cache hits, and races both discovery and full-definition loading. If no git root is found, the local provider treats the supplied cwd itself as the project root.
 
+Full definitions are not cached by the registry. Each `get()` calls the winning provider with the selected candidate, so the local provider rereads the current body. A definition whose name no longer matches that candidate is rejected and invalidates the exact provider for rediscovery.

+Before each later model step, the consumer applies exact tool visibility and digests the exact rendered entries between the `` tags from a complete snapshot. It derives the comparison baseline from the same entries in the newest recognizable visible catalog message sourced by the plugin. A changed digest appends a durable full replacement through `agent.inject()`; deleting every skill appends an explicit empty replacement. Incomplete snapshots preserve the last-good model view. If compaction hides every historical catalog message, the next complete snapshot re-establishes the current catalog; an empty view with no prior catalog emits nothing. These catalog messages are session history, not World State.
+
+The model-facing `skill({ name })` tool validates the kebab-case name, finds the summary in the invocation-neutral catalog, rejects it before loading unless `isModelInvocable` permits access, then rereads the complete definition for the calling agent cwd and rechecks the policy before returning content. It reports an unresolved skill as unknown or no longer available and returns a tool result containing ``, ``, and ``. `resourceBase` resolves explicitly referenced scripts, references, and assets only as needed; the loaded result does not enumerate a skill directory. Body-only edits therefore change later tool calls without producing catalog messages or rewriting earlier tool results.

+- `pre-commit` applies formatting-only ESLint fixes, validates the staged files with Oxlint and applies its native fixes, checks the staged diff for whitespace errors, and runs the vendor manifest guard.
 - `pre-push` runs only the incremental repository typecheck (`tsc -b` over the root solution, covering both the host and client aggregates).
 
 The vendor manifest guard checks that changes under `vendor/*/src` are staged with the matching `vendor/README.md` manifest update. See `vendor/README.md` before editing vendored code.

-  Blob hashes, not commit hashes, so the record is computable for files edited in the same PR (`git hash-object foo.md`) and consistency is a pure content comparison.

+  Blob hashes, not commit hashes, so the record is computable for files edited in the same PR (`git hash-object foo.md`) and consistency is a pure content comparison. `--write` stores those snapshots in the local Git object database before recording them, including uncommitted working-tree contents, and pins every distinct stored blob under a content-addressed `refs/dsh/translation-pairing/snapshots/` ref so garbage collection cannot invalidate a recorded recovery pointer. The recorded hashes therefore recover the exact last-confirmed text of either side, so an out-of-sync pair is updated by patching the counterpart minimally against the edited side's diff — never by re-translating whole files. `pnpm run gen-translation-brief ` assembles that update's working set mechanically at the narrowest safely aligned granularity — changed Markdown units, then heading sections, then whole document — with the edited side's diff since last confirmation, each changed span's three-way text, the terminology rows the change touches, and the binding update rules; a change confined to the pair's byte-identical code fences is computed outright, and `--apply` splices it into the counterpart after structural validation ([briefed-updates Agent Note](../../.agents/notes/implemented/process/2026-07-26-briefed-minimal-translation-updates.md)).

 - **Language switcher.** Both files link to each other immediately after their H1 heading: the English file carries `English | [中文](foo.zh.md)` and the Chinese file carries `[English](foo.md) | 中文`.
 - **Structure mirrors the counterpart.** Heading depths and order, list kinds, ordered-list starts, list item counts, table row and column counts, link targets, and verbatim code blocks match one to one across the pair — see [translation-rules.md](translation-rules.md) for the full preservation rules. Existing Markdown gates apply to `.zh.md` files unchanged (`verify-md-wrap`, `verify-md-links`).

+  用 blob hash 而不是 commit hash，这样同一个 PR 里改动的文件也能算出记录（`git hash-object foo.md`），一致性是纯内容比较。`--write` 会先把这些快照存入本地 Git 对象库再写下记录，未提交的工作树内容也不例外；它还会在内容寻址的 `refs/dsh/translation-pairing/snapshots/` ref 下固定每个不同的已存 blob，使垃圾回收无法让已记录的恢复指针失效。因此记录的 hash 能还原任一侧上次确认时的确切文本，所以失去同步的配对是「按被改一侧的 diff 最小化地修补另一侧」，从不整篇重译。`pnpm run gen-translation-brief ` 会以能安全对齐的最窄粒度——先是有改动的 Markdown 单元，再是标题小节，最后是整篇文档——机械地汇集这次更新的工作集：被改一侧自上次确认以来的 diff、每个改动块的三方文本、改动触及的术语表行，以及有约束力的更新规则；仅落在配对中逐字节一致的围栏代码块内的改动可以直接算出，`--apply` 则经结构签名校验后把它拼接进对侧文件（[briefed-updates Agent Note](../../.agents/notes/implemented/process/2026-07-26-briefed-minimal-translation-updates.md)）。两侧对齐后，`pnpm run verify-translation-pairing --write ` 重新记录两个 hash；那份 yaml diff 就是「确认一致」这个动作本身，可以被评审，也正因如此，`--write` 要求点名你确认过的配对（`--write --all` 是显式的全语料形式）。
 - **语言切换行。** 两个文件在各自 H1 标题之后立即互链：英文文件带 `English | [中文](foo.zh.md)`，中文文件带 `[English](foo.md) | 中文`。
 - **结构与另一侧一一对应。** 标题深度与顺序、列表类型、有序列表起始编号、列表项数量、表格行列数、链接目标与逐字节一致的代码块在配对两侧一一对应；完整保持规则见 [translation-rules.md](translation-rules.md)。既有 Markdown 门禁对 `.zh.md` 文件原样生效（`verify-md-wrap`、`verify-md-links`）。

 - **Coverage gate** (`pnpm run test:coverage`): the gating run, per-file 100% on `packages/*/*/src`. An uncovered line is often dead code the gate is correctly flagging for deletion, not a missing test to bolt on. Line coverage is necessary, never sufficient — it proves lines ran, not that the feature works as shipped.
 - **Real-API e2e** (`pnpm run test:e2e`): with-key tests against live provider APIs — the DeepSeek model plus provider-specific smokes that gate on their own keys (`EXA_API_KEY`, `PERPLEXITY_API_KEY`, …); each suite self-skips without its key so keyless CI stays green ([real-API e2e Agent Note](../.agents/notes/implemented/testing/2026-06-19-real-api-e2e-ci.md)).
 - **Snapshot** (`pnpm run test:snapshot`): keyless expected outputs cover external behavior — transport contracts and presentation, while persisted logs pin assembled backend behavior. ACP boots the real automation-server example, replays a recorded session, and diffs normalized JSON-RPC plus the re-persisted log ([ACP snapshot Agent Note](../.agents/notes/implemented/testing/2026-06-19-acp-snapshot-tests.md)); headless pins `stream-json` through its real one-shot process. TUI journeys replay primary/child JSONL through the real loop and tools, then project ANSI into semantic terminal-state outputs; package snapshots retain transient states and a real PTY covers the process boundary ([TUI snapshot Agent Note](../.agents/notes/implemented/testing/2026-07-18-tui-terminal-state-snapshots.md)). Use `pnpm run test:snapshot:record` when a model transcript changes and `pnpm run test:snapshot:refresh` when replay input remains valid; review every JSONL and expected-output diff. One ACP scenario (`text-turn`) pins full system-prompt/tool-schema content; other fixtures tokenize it so an edit churns one line ([pinned-header Agent Note](../.agents/notes/archived/testing/2026-07-06-pin-request-header-content-in-one-scenario.md)).

+- **Web browser snapshot** (`pnpm run test:web`; required Linux PR gate): Chromium compares replayed browser output with `apps/web/tests/snapshots/`. CI forces read-only `DSH_SNAPSHOT=replay`, never writing expected outputs; record/refresh stay local and every diff is reviewed ([web e2e lane](../.agents/notes/implemented/testing/2026-07-24-web-gui-browser-e2e-lane.md), [CI gate decision](../.agents/notes/implemented/testing/2026-07-30-web-browser-snapshot-ci-gate.md)). `test:web` [builds first](../.agents/notes/implemented/bug-fix/2026-07-28-themed-scrollbars-and-reserved-gutter.md) for plugin CSS.
 
 Committed session-format JSONL uses the canonical packed-row layout, and the keyless snapshot gate discovers every such fixture by its `session` header. In-flight branches carrying older fixture edits merge current `master` and run the [temporary migrator](../scripts/migrate-packed-session-fixtures.ts) through `pnpm run migrate:packed-session-fixtures`; the [removal proposal](../.agents/notes/proposed/process/2026-07-26-remove-packed-session-fixture-migrator.md) retires that command and these links after all affected branches converge.

+# Typert Catalog Integration Design
+
+English | [中文](typert-catalog-integration-design.zh.md)
+
+## Current State and Problem
+
+Typert already provides separate host/client `FaceModel` instances, a `TypeGraph` with explicit cross-face references, and analysis support for services, events, `@typert object`, generics, inheritance, and External types. The TypeScript compiler API should only translate source code into this standard model; downstream consumers should not traverse the TypeScript AST again.
+
+The repository currently has two catalog pipelines that analyze TypeScript source directly: the static API catalog consumed by `tool-cordis`, and the generation and freshness gate for `docs/cordis-catalog/events.md` and `docs/cordis-catalog/services.md`. They analyze the same services, events, and related types, but maintain separate collection and rendering logic, so they cannot prove that the Typert model is sufficient to represent the existing domain semantics.
+
+The first phase makes both pipelines consume the Typert model while keeping the three committed artifacts character-for-character identical to their pre-migration versions:
+
+- `docs/cordis-catalog/events.md`
+- `docs/cordis-catalog/services.md`
+- `packages/cordis/tool-cordis/src/api-catalog.ts`
+
+This phase does not require product plugins to publish Typert subpaths, example applications to load Typert, or changes to the runtime dependencies of `tool-cordis`.
+
+## Options
+
+### Drive `tool-cordis` from the Runtime Registry
+
+Each plugin publishes and loads Typert artifacts, then `tool-cordis` reads the current runtime model from `ctx.typert`. This path reflects the set of plugins actually loaded, but it requires every product package represented in the catalog to add package exports, generated artifacts, registry contributions, and application assembly. That integration surface is much larger than the analysis capability being validated now.
+
+### Publish Typert Artifacts Repository-Wide, Then Aggregate Them Statically
+
+All product packages generate host/client JS and DTS during the normal build/typecheck process, then the catalog generator aggregates those artifacts. This path establishes the complete publication protocol up front, but it also changes many package manifests and the build topology at once, coupling catalog migration to repository-wide Typert publication.
+
+### Analyze at Build Time, Then Project the Catalog
+
+`WorkspaceAnalyzer` builds a `WorkspaceModel` and `TypeGraph` from the host TypeScript project. The repository-specific `CordisCatalogProjector` consumes only that model and generates the three texts. `tool-cordis` continues to import the committed static `api-catalog.ts`, so the runtime does not need the Typert service.
+
+This phase uses build-time projection. It directly verifies that the standard Typert model can replace the existing AST collector while leaving runtime publication and automatic loading to separate follow-up decisions.
+
+## Phase-One Architecture

+        ├── docs/cordis-catalog/services.md
+        └── packages/cordis/tool-cordis/src/api-catalog.ts
+```
+
+The objects have the following responsibilities:
+
+- `WorkspaceAnalyzer` analyzes packages, exports, services, events, type declarations, and reference relationships, and produces a compiler-independent model.
+- `WorkspaceModel` and `TypeGraph` are the standard data structures shared by all generation and scanning analyses. They preserve developer-authored generics, inheritance, and type trees without retaining the TypeScript AST.
+- The root entry point of `@deepseek-ai/dsh-typert-generator` exports `CordisCatalogProjector`, which performs model-driven selection, sorting, summary extraction, source location handling, JSDoc completeness checks, type-link closure, and rendering in three text formats. Its implementation remains in a dedicated Cordis catalog file, but it does not create another package subpath or embed a list of repository type names.
+- `scripts/gen-cordis-catalog.ts` provides `LINK_MAP`, `FOUNDATION_TYPE_NAMES`, `TYPE_LINK_EXEMPTIONS`, and the inherited Cordis list, injects them explicitly into the projector through `CordisCatalogPolicy`, and owns the write/check CLI behavior. The vendor Cordis core pages continue to be generated by a separate pinned-source projector.
+- `tool-cordis` imports only the static `api-catalog.ts` and does not depend on `typert-registry` or `typert-loader`.
+
+`CordisCatalogProjector` is a repository-specific downstream consumer and is not part of Typert's general-purpose model. When adding another category, first extend the standard model, then add the corresponding projector. The Typert analyzer must not absorb Cordis documentation formats or `tool-cordis` presentation logic.
+
+## Model Additions
+
+In addition to type structure, the catalog's character-for-character projection needs the declaration forms written by developers and exact source locations. The standard model therefore retains event/service locations, body-free text for events and members, parameter initializers, and the export status and canonical text of type declarations. `SourceDeclarationModel` also indexes top-level exported declarations for ambiguity checks and static type closure, without promoting them to domain graph roots.
+
+```ts
+interface SourceLocation {
+  readonly file: string
+  readonly line: number
+  readonly column: number
+}
+
+interface EventModel {
+  readonly location: SourceLocation
+  readonly text: string
+}
+```
+
+Repository-wide analysis supports building bounded `ts.Program` instances in package batches, then merging them through source-location-stable graph ids into a face model equivalent to monolithic analysis. This capability changes only the memory boundary of the compiler program; it does not change package, declaration, or type graph semantics.
+
+All information required by the projector must come from `WorkspaceModel` or `TypeGraph`. If a fact required for character-for-character compatibility cannot be expressed by the model, extend the standard model; do not reintroduce `ts.Node`, `ts.Symbol`, or `ts.TypeChecker` in the projector or script.
+
+## Character-for-Character Migration Oracle
+
+Before migration, retain the three texts produced by the old generator against the same source state. After migration, run the new analyzer and projector and require the three outputs to be byte-for-byte identical. Newlines, spaces, ordering, JSDoc, source pointers, and generated headers are all part of the comparison.
+
+`pnpm run verify-cordis-catalog` retains its `--check` mode, which reads the three committed artifacts and compares them directly with the newly computed results. A missing file or any differing character makes the artifact stale, and the error points to the single `pnpm run gen-cordis-catalog` repair command.
+
+Tests pin both of the following layers:
+
+- Typert fixture snapshots pin the `WorkspaceModel`, `TypeGraph`, JS, DTS, and Zod outputs, proving the behavior of the standard model and general-purpose emitters.
+- Cordis catalog tests or snapshots pin the projector's three complete texts, proving that the repository-specific product projection does not bypass the standard model and providing directly reviewable textual evidence.
+
+The three committed artifacts are the migration oracle between the old and new implementations and the continuing freshness oracle after migration. The old `gen-cordis-api` AST collector is removed. The scripts and commands with that name remain only as compatibility entry points for the unified projector because the generated file header itself contains the command; retaining the entry point preserves the character-for-character oracle without creating a second source of truth.
+
+## Exact Change List
+
+### Typert Generator
+
+- Add the locations, authored declaration text, parameter initializers, export status, and top-level source declaration index needed for character-for-character projection, with coverage in analyzer and model snapshots.
+- Support bounded package-batch analysis and prove that direct and batched models are equivalent.
+- Confirm that the catalog's required service declarations, public instance members, JSDoc, generics, inheritance, and referenced types are all available from the model.
+- Keep the TypeScript compiler API encapsulated within the analyzer; the public model and projector inputs do not expose compiler objects.
+
+### Cordis Catalog Projector
+
+- Select the complete set of Cordis services and events from the host `WorkspaceModel`.
+- Preserve the old generator's JSDoc rules: events must have `@mode` and payload `@param` tags; service methods must have a matching `@param` for every parameter; non-void returns must have `@returns`.
+- Compute the type links used by signatures and the transitive public type closure required by `tool-cordis` from the type graph.
+- Receive caller-maintained type classifications and the inherited surface through an explicit `CordisCatalogPolicy`; do not maintain the repository documentation taxonomy inside the generator package.
+- Preserve the existing output rules for source pointers, signatures, summaries, ordering, declaration truncation, and the inherited context catalog.
+- Project once and render the events Markdown, services Markdown, and TypeScript API catalog, preventing drift between documentation and tool data.
+
+### Commands and Consumers
+
+- `scripts/gen-cordis-catalog.ts` maintains repository policy data, assembles the analyzer and projector, and writes/checks all three artifacts together. Parsing, validation, and rendering logic lives in the generator's dedicated Cordis source file and is exported uniformly from the package root entry point.
+- Narrow `scripts/gen-cordis-api.ts` to a logic-free compatibility entry point for the unified CLI; the root `gen-cordis-api` and `verify-cordis-api` aliases point to that entry point.
+- Restore the static catalog default in `tool-cordis` and remove its dependencies on `ctx.typert`, `typert-registry`, and runtime package-model completeness.
+- `gen-doc-graphs` obtains the projector's model-level result once and reuses its services and events; it must not continue to import the AST collector or analyze the repository again.
+
+### Narrow the Scope of Phase-One Changes
+
+- Remove the newly added `./typert` and `./client/typert` exports and `lib/typert.*` files from product plugin package.json files.
+- Remove `typert-registry` and `typert-loader` assembly from examples.
+- Normal build/typecheck does not run repository-wide `gen-typert` or require product-package Typert artifacts to exist before it runs on a clean tree.
+- Retain `packages/typert/generator`, `packages/typert/registry`, and `packages/typert/loader`, along with their independent fixture, emitter, and runtime registration tests.
+
+## Future Extensions
+
+The runtime registry remains the receiving and query layer for generated JS/Zod, and the loader remains the automatic loading mechanism; neither supplies data to the first-phase static catalog. When product packages need runtime reflection, they can opt in by publishing `package/typert` and `package/client/typert`, which the loader then registers with `ctx.typert`.
+
+Future integration does not change the phase-one layering: only the analyzer handles TypeScript, the standard model serves both static generation and scan analysis, and the emitter produces runtime artifacts from that same model. Whether to extend publication to more packages, enable the loader by default, or extend the runtime registry's query capabilities are separate review decisions and remain decoupled from the Cordis catalog migration.

+# Typert catalog 接入设计

+
+## 现状与问题
+
+Typert 已经具备独立的 host/client `FaceModel`、可显式跨 face 引用的 `TypeGraph`，以及 service、event、`@typert object`、泛型、继承和 External 类型的分析能力。TypeScript compiler API 只应负责把源码转换成这套标准模型；后续消费者不应再次遍历 TypeScript AST。
+
+仓库目前有两条直接分析 TypeScript 源码的 catalog 链路：`tool-cordis` 使用的静态 API catalog，以及 `docs/cordis-catalog/events.md`、`docs/cordis-catalog/services.md` 的生成与 freshness gate。它们分析的是同一批 service、event 和相关类型，却分别维护收集与渲染逻辑，不能证明 Typert 模型足以承载现有业务语义。
+
+第一阶段的目标是让这两条链路共同消费 Typert 模型，并保持三份已提交产物与迁移前字符级一致：
+
+- `docs/cordis-catalog/events.md`
+- `docs/cordis-catalog/services.md`
+- `packages/cordis/tool-cordis/src/api-catalog.ts`
+
+本阶段不要求业务插件发布 Typert 子路径，不要求示例应用加载 Typert，也不改变 `tool-cordis` 的运行时依赖关系。
+
+## 可选路径
+
+### 运行时 registry 驱动 `tool-cordis`
+
+每个插件发布并加载 Typert 产物，`tool-cordis` 再从 `ctx.typert` 读取当前运行时模型。这条路径可以反映实际加载的插件集合，但会要求所有参与 catalog 的业务包增加 package exports、生成产物、registry contribution 和应用装配，接入面远大于当前要验证的分析能力。
+
+### 全仓发布 Typert 产物后静态汇总
+
+所有业务包在普通 build/typecheck 中生成 host/client JS 与 DTS，再由 catalog 生成器汇总这些产物。这条路径能够提前建立完整的发布协议，但会同时修改大量 package manifest 和构建拓扑，使 catalog 迁移与 Typert 的全仓发布绑定。
+
+### 构建期分析后投影 catalog
+
+`WorkspaceAnalyzer` 从 host TypeScript project 构建 `WorkspaceModel` 与 `TypeGraph`，仓库专用的 `CordisCatalogProjector` 只消费该模型并生成三份文本。`tool-cordis` 继续导入已提交的静态 `api-catalog.ts`，运行时不需要 Typert service。
+
+本阶段采用构建期投影。它直接验证 Typert 标准模型能否替代现有 AST collector，同时把运行时 publication 和自动加载留在独立的后续决策中。

+```
+
+各对象的职责如下：
+
+- `WorkspaceAnalyzer` 负责 package、export、service、event、类型声明和引用关系的分析，并产生 compiler-independent model。
+- `WorkspaceModel` 与 `TypeGraph` 是所有生成和扫描分析共用的标准数据结构，保留开发者写出的泛型、继承和类型树，不保存 TypeScript AST。
+- `@deepseek-ai/dsh-typert-generator` 根入口导出的 `CordisCatalogProjector` 负责模型驱动的选择、排序、摘要、源位置、JSDoc 完整性、类型链接闭包和三种文本格式；实现仍单独放在 Cordis catalog 专用文件中，但不形成额外的 package subpath，也不内置仓库类型名单。
+- `scripts/gen-cordis-catalog.ts` 提供 `LINK_MAP`、`FOUNDATION_TYPE_NAMES`、`TYPE_LINK_EXEMPTIONS` 和 inherited Cordis 清单，通过 `CordisCatalogPolicy` 显式注入 projector，并负责 write/check 的命令行行为；vendor Cordis core 页面仍由独立的 pinned-source projector 生成。
+- `tool-cordis` 只导入静态 `api-catalog.ts`，不依赖 `typert-registry` 或 `typert-loader`。
+
+`CordisCatalogProjector` 是仓库业务消费者，不进入 Typert 通用模型。新增其他类别时，先扩展标准模型，再增加对应 projector；Typert analyzer 不吸收 Cordis 文档格式或 `tool-cordis` 展示逻辑。
+
+## 模型补充
+
+Catalog 的字符级投影除了类型结构，还需要开发者写下的声明形式和精确源码位置。标准模型因此保留 event/service location、event/member 的 body-free text、parameter initializer，以及 type declaration 的 export 状态和 canonical text；`SourceDeclarationModel` 另外索引顶层导出声明，供歧义检查和静态类型闭包使用，但不把它们提升为业务 graph root。
+
+```ts
+interface SourceLocation {
+  readonly file: string
+  readonly line: number
+  readonly column: number
+}
+
+interface EventModel {
+  readonly location: SourceLocation
+  readonly text: string
+}
+```
+
+全仓分析支持按 package 分批构建有界 `ts.Program`，再依靠源码位置稳定的 graph id 合并为与一次性分析等价的 face model。该能力只改变 compiler program 的内存边界，不改变 package、declaration 或 type graph 语义。
+
+projector 所需信息必须来自 `WorkspaceModel` 或 `TypeGraph`。如果字符级兼容需要的事实无法从模型表达，应补充标准模型；不得在 projector 或脚本中重新引入 `ts.Node`、`ts.Symbol` 或 `ts.TypeChecker`。
+
+## 字符级迁移 oracle
+
+迁移前，在同一份源码状态下保留旧生成器产生的三份文本。迁移后运行新的 analyzer 与 projector，要求三份输出逐字节相等；换行、空格、排序、JSDoc、source pointer 和生成头都属于比较内容。
+
+`pnpm run verify-cordis-catalog` 的 `--check` 模式继续读取三份 committed artifact，并与本次计算结果直接比较。任一文件缺失或任一字符不同都视为 stale，错误信息指向统一的 `pnpm run gen-cordis-catalog` 修复命令。
+
+测试同时固定以下两层：
+
+- Typert fixture snapshots 固定 `WorkspaceModel`、`TypeGraph`、JS、DTS 与 Zod 输出，证明标准模型和通用 emitter 的行为。
+- Cordis catalog 测试或 snapshot 固定 projector 的三份完整文本，证明仓库业务投影没有绕过标准模型，并给出可直接评审的文本证据。
+
+三份 committed artifact 是旧实现与新实现的迁移 oracle，也是迁移完成后的持续 freshness oracle。旧 `gen-cordis-api` AST collector 被删除；同名脚本和命令只作为统一 projector 的兼容入口保留，因为生成文件头本身包含该命令，保留入口可以维持字符级 oracle 而不产生第二套真源。
+
+## 精确改造清单
+
+### Typert generator
+
+- 补齐字符级投影所需的 location、authored declaration text、parameter initializer、export 状态和顶层 source declaration index，并在 analyzer 与 model snapshots 中覆盖。
+- 支持有界 package batch 分析，并证明 direct 与 batched model 等价。
+- 确认 catalog 所需的 service 声明、public instance member、JSDoc、泛型、继承和引用类型均可从 model 读取。
+- 保持 TypeScript compiler API 封装在 analyzer 内；公共 model 和 projector 输入不暴露 compiler 对象。
+
+### Cordis catalog projector
+
+- 从 host `WorkspaceModel` 选择完整的 Cordis service/event 集合。
+- 保留旧生成器的 JSDoc 规则：event 必须有 `@mode` 和 payload `@param`，service method 必须有参数对应的 `@param`，非 void 返回必须有 `@returns`。
+- 从 type graph 计算签名涉及的类型链接和 `tool-cordis` 所需的传递 public type closure。
+- 通过显式 `CordisCatalogPolicy` 接收调用方维护的类型分类和 inherited surface，不在 generator 包内维护仓库文档 taxonomy。
+- 保留 source pointer、签名、摘要、排序、声明截断和 inherited context catalog 的既有输出规则。
+- 一次投影并渲染 events Markdown、services Markdown 与 TypeScript API catalog，避免文档和工具数据漂移。
+
+### 命令与消费方
+
+- `scripts/gen-cordis-catalog.ts` 维护仓库 policy 数据、组装 analyzer/projector，并同时 write/check 三份产物；解析、校验和渲染逻辑位于 generator 的 Cordis 专用源文件，并统一从 package 根入口导出。
+- 将 `scripts/gen-cordis-api.ts` 收窄为统一 CLI 的无逻辑兼容入口；根目录的 `gen-cordis-api`、`verify-cordis-api` aliases 指向该入口。
+- `tool-cordis` 恢复静态 catalog 默认值，移除对 `ctx.typert`、`typert-registry` 和运行时 package model 完整性的依赖。
+- `gen-doc-graphs` 一次取得 projector 的 model-level 结果并复用 services/events，不能继续导入 AST collector 或重复分析全仓。
+
+### 收窄本阶段改动面
+
+- 撤销业务插件 package.json 中新增的 `./typert`、`./client/typert` exports 和 `lib/typert.*` files。
+- 撤销 examples 中的 `typert-registry`、`typert-loader` 装配。
+- 普通 build/typecheck 不运行全仓 `gen-typert`，也不要求 clean tree 预先存在业务包 Typert artifact。
+- 保留 `packages/typert/generator`、`packages/typert/registry`、`packages/typert/loader` 及其独立 fixture、emitter 和 runtime registration 测试。
+
+## 后续扩展
+
+Runtime registry 继续作为生成 JS/Zod 后的接收与查询层，loader 继续作为自动装载机制；两者不承担第一阶段静态 catalog 的数据来源。业务包需要运行时反射时，可以按 package opt-in 发布 `package/typert` 与 `package/client/typert`，再由 loader 注册到 `ctx.typert`。
+
+后续接入不改变本阶段的分层：TypeScript 只进入 analyzer，标准模型同时服务静态生成与扫描分析，runtime artifact 由 emitter 从同一模型产生。是否把更多 package 接入 publication、是否默认启用 loader，以及 runtime registry 最终提供哪些查询能力，分别评审，不与 Cordis catalog 迁移捆绑。

+## CLI overlays

+The TUI composes `base.cordis.yml` and `tui.cordis.yml`, then applies one optional patch list. By default that final list is `~/.dsh/config.yaml`; `dsh --config ` replaces the personal list with the named overlay. `dsh --config-replace ` instead boots the named file as the complete tree, without shipped or personal layers. `dsh web --config ` adds its overlay after the shared base and Web surface defaults and before Web profile and CLI-flag patches.
+
+A patch replaces a row's entire `config` value; it does not deep-merge keys. For example, patching `llm-deepseek` with only `config: { thinking: disabled }` also removes that row's configured `apiKey` and `baseURL`, so restate every key the row must retain.

+Stdout 只携带以换行分隔的 ACP JSON-RPC。`@deepseek-ai/dsh-acp-demo` 不安装 stdout logger；该叶节点新增的组件必须使用 stderr 输出诊断信息。
 
 自动化契约（支持的方法、基线提示词内容、已提交文本输出，以及有意缺少的 UI 界面）位于 [`@deepseek-ai/dsh-acp`](../../packages/acp/acp/README.md)。
 
 ## 会话 workspace 与权限
 
-每次 `session/new` 都提供一个绝对 `cwd`。受沙箱限制的 bash 与文件系统变更会根据该会话 cwd 解析 `workspace-write`，因此并发会话可以使用不同的项目根目录；平台临时根目录仍是共享可写暂存空间（参见[沙箱契约](../../packages/sandbox/sandbox/README.md)）。`DSH_PERMISSION_MODE` 在部署和测试中选择 `workspace-write` 或 `danger-full-access`。

 ## 快照测试
 
-此示例拥有 ACP 快照套件。它会启动真实自动化服务器，通过 `dsh-llm-replay` 回放已提交的模型流，并比较规范化后的协议输出与重新持久化的会话日志。录制使用真实模型；刷新会复用已提交的回放输入。覆盖场景包括抛出／挂起行为，可选 `workspace/` fixture（测试前置数据）则为外部状态检查预置环境。

 大多数场景锁定后端行为，而非 ACP 专用行为；[仅面向自动化的 ACP 决策](../../.agents/notes/implemented/simplification/2026-07-23-acp-automation-only-protocol.md#snapshot-boundary)说明了为何该覆盖仍与传输层耦合。

-You are an AI agent powered by the DeepSeek Harness SDK.
-
-You are a coding assistant powered by the deepseek-v4-flash model. Your working directory is {{cwd}}.
-
-Verify your work by running the code or tests. Keep answers brief and factual.
-
-
-Use the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.
-
-Use the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.
-
-Use the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.
-
-Check the [exit code: N] marker on every bash result; investigate failures before moving on.
-
-Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
-
-Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
-
-Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`).
-
-
-Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
-
-Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.
-
-## Writing code for run_code
-
-Pass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:
-
-- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools["my-tool"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.
-- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.
-- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.
-- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.
-
-The available tools:
-
-```ts
-type JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }
-
-interface ToolArgsMap {
-  /** Execute a bash command (`bash -c`) and return its stdout/stderr. Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under  mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later. */

-  /** Run a JavaScript workflow script that orchestrates subagents at scale. Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them. The run executes in the foreground: this call returns when the whole script finishes. */

-You are an AI agent powered by the DeepSeek Harness SDK.
-
-You are a coding assistant powered by the deepseek-v4-flash model. Your working directory is {{cwd}}.
-
-Verify your work by running the code or tests. Keep answers brief and factual.
-
-
-Use the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.
-
-Use the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.
-
-Use the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.
-
-Check the [exit code: N] marker on every bash result; investigate failures before moving on.
-
-Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
-
-Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
-
-Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`).
-
-
-Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
-
-Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.
-
-## Writing code for run_code
-
-Pass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:
-
-- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools["my-tool"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.
-- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.
-- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.
-- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.

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

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them. The run executes in the foreground: this call returns when the whole script finishes. */

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

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them. The run executes in the foreground: this call returns when the whole script finishes.",

-You are an AI agent powered by the DeepSeek Harness SDK.
-
-You are a coding assistant powered by the deepseek-v4-flash model. Your working directory is {{cwd}}. Your bash tool runs under a file sandbox — a `[sandbox: file access denied …]` result is policy, not a command bug.
-
-Verify your work by running the code or tests. Keep answers brief and factual.
-
-
-Use the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.
-
-Use the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.
-
-Use the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.
-
-Check the [exit code: N] marker on every bash result; investigate failures before moving on.
-
-Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
-
-Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
-
-Approval prompts are disabled in this session: actions that require approval are rejected automatically — do not request sandbox escalation (do not set `sandbox_permissions`).
-
-
-Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
-
-Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under  mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a task id immediately; read its output with `task_output` and stop it with `task_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later.",

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

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

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

-English | [中文](README.zh.md)
-
-The self-referential harness demo: the DeepSeek V4 coding spine on the full-screen TUI plus [`@deepseek-ai/dsh-tool-cordis`](../../packages/cordis/tool-cordis/README.md), which lets the model inspect the current DSH process, mount in-memory temporary Plugins, and unmount them. Temporary Plugins remain active across turns but disappear on unmount, toolset unload, or DSH restart; they create no files or configuration and may affect other sessions in the process. The `ctx.fs` and `ctx.web` services are provider-only capabilities available to those Plugins. The design lives in [the toolset Agent Note](../../.agents/notes/implemented/feature/2026-07-08-self-referential-cordis-toolset.md).
-
-## Run it
-
-```sh
-# repo root .env (gitignored) or exported env:
-#   DEEPSEEK_API_KEY=sk-…
-#   DEEPSEEK_BASE_URL=https://…   # optional; defaults to the public API
-pnpm run demo:cordis      # TUI (default)
-pnpm run demo:cordis web  # browser UI at http://127.0.0.1:3081
-pnpm run demo:cordis acp  # ACP server
-```
-
-The intended demo is staged — verify the listener link first, then let the agent extend itself:
-
-```
-> Mount a temporary Plugin that listens to the 'agent/status' event and logs every status change, then run `echo hi` with bash.
-  [tool call] cordis_mount({"code": "return { name: 'status-logger', apply(ctx) { ctx.on('agent/status', (agent, status) => console.log('status →', status)) } }"})
-  [tool result] Temporary Plugin dyn-1 is running (plugin "status-logger"; available until unmounted or DSH restarts).
-  [tool call] bash({"command": "echo hi"})
-[cordis:dyn-1] status → …            ← the temporary listener firing, live
-> Now give yourself a reverse_text tool and use it on "harness".
-  [tool call] cordis_mount({"code": "return { name: 'reverse-text', inject: ['tools'], apply(ctx) { ctx.tools.register(harness.defineTool({ name: 'reverse_text', … })) } }"})
-  [tool call] reverse_text({"text": "harness"})   ← a tool the agent built for itself, one step earlier
-> Unmount both temporary Plugins.
-  [tool call] cordis_unmount({"id": "dyn-1"})
-```
-
-Ask for `cordis_inspect` with `what: "api"` or `what: "events"` to see the generated service/event reference used to write Plugin code, and mount two cooperating temporary Plugins (`ctx.provide` in one, `inject` in the other) to watch Cordis park and revive the consumer.
-
-## End-to-end tests
-
-`tests/keyless-smoke.e2e.ts` boots the real `cordis.yml` through the Loader with a dummy key and asserts the banner, package-name resolution, and clean EOF exit. `tests/cordis-tools.e2e.ts` is the with-key smoke: a real model mounts a temporary status listener and the test verifies its tagged console line, creates and uses a `reverse_text` tool, and composes two temporary Plugins through provide/inject. [`packages/cordis/tool-cordis`](../../packages/cordis/tool-cordis) carries the unit coverage under the per-file 100% gate.

-# cordis-agent

-[English](README.md) | 中文
-
-自指 harness 演示：在全屏 TUI 上运行 DeepSeek V4 编码主干，并加载 [`@deepseek-ai/dsh-tool-cordis`](../../packages/cordis/tool-cordis/README.md)。后者让模型检查当前 DSH 进程、挂载仅存于内存的临时 Plugin，并再次卸载它们。临时 Plugin 可跨 turn 保持活跃，但会在卸载、工具集卸载或 DSH 重启后消失；它们不创建文件或配置，也可能影响同一进程中的其他 session。`ctx.fs` 和 `ctx.web` 是这些 Plugin 可用的 provider-only 能力。设计详见[工具集 Agent Note](../../.agents/notes/implemented/feature/2026-07-08-self-referential-cordis-toolset.md)。
-
-## 运行
-
-```sh
-# repo root .env (gitignored) or exported env:
-#   DEEPSEEK_API_KEY=sk-…
-#   DEEPSEEK_BASE_URL=https://…   # optional; defaults to the public API
-pnpm run demo:cordis      # TUI (default)
-pnpm run demo:cordis web  # browser UI at http://127.0.0.1:3081
-pnpm run demo:cordis acp  # ACP server
-```
-
-预期演示分阶段进行：先验证监听器链接，再让 agent 扩展自身：
-
-```
-> Mount a temporary Plugin that listens to the 'agent/status' event and logs every status change, then run `echo hi` with bash.
-  [tool call] cordis_mount({"code": "return { name: 'status-logger', apply(ctx) { ctx.on('agent/status', (agent, status) => console.log('status →', status)) } }"})
-  [tool result] Temporary Plugin dyn-1 is running (plugin "status-logger"; available until unmounted or DSH restarts).
-  [tool call] bash({"command": "echo hi"})
-[cordis:dyn-1] status → …            ← the temporary listener firing, live
-> Now give yourself a reverse_text tool and use it on "harness".
-  [tool call] cordis_mount({"code": "return { name: 'reverse-text', inject: ['tools'], apply(ctx) { ctx.tools.register(harness.defineTool({ name: 'reverse_text', … })) } }"})
-  [tool call] reverse_text({"text": "harness"})   ← a tool the agent built for itself, one step earlier
-> Unmount both temporary Plugins.
-  [tool call] cordis_unmount({"id": "dyn-1"})
-```
-
-请求 `cordis_inspect` 并使用 `what: "api"` 或 `what: "events"`，即可查看编写 Plugin 代码所用的生成服务／事件资料。还可挂载两个协作临时 Plugin（一个中调用 `ctx.provide`，另一个中使用 `inject`），观察 Cordis 如何暂停并恢复消费方。
-
-## 端到端测试
-
-`tests/keyless-smoke.e2e.ts` 使用虚拟密钥通过 Loader 启动真实 `cordis.yml`，并断言横幅、包名解析和 EOF 后干净退出。`tests/cordis-tools.e2e.ts` 是带密钥的冒烟测试：真实模型挂载一个临时状态 listener，测试验证其带标记的 console 行；然后创建并使用 `reverse_text` 工具，再通过 provide/inject 组合两个临时 Plugin。[`packages/cordis/tool-cordis`](../../packages/cordis/tool-cordis) 在每文件 100% 覆盖率门禁下承载单元覆盖。

-    persona: |
-      You are cordis-agent, a self-referential harness demo powered by the
-      {{model}} model.
-
-      You run INSIDE a cordis plugin runtime, and your cordis_* tools operate
-      on that live runtime: cordis_inspect to look around (its `api` and
-      `events` sections document the service methods, type shapes, and events
-      your Plugin code can use), cordis_mount to mount an in-memory temporary
-      Plugin (an event listener, a brand-new tool for yourself, or a service
-      another temporary Plugin injects), cordis_unmount to clean one up. These
-      Plugins remain across turns but disappear on unmount, toolset unload, or
-      DSH restart and may affect other sessions in this process. In Plugin code, NEVER use Node
-      built-ins (require/setTimeout/fetch) — use the runtime's cordis services
-      via inject: fs, web, bash, and timer (ctx.setTimeout). Prefer small
-      single-purpose plugins, prefer plain notification events over waterfall
-      events unless you intend to intercept, and unmount what you no longer
-      need. Report results briefly.

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

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.

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

Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files.

Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

BEFORE calling a service from your code, read cordis_inspect what:\"api\" — it lists method signatures AND the type shapes of their arguments/returns (do not guess a field's type; e.g. a bash run's stdout is an object, not a string). Inside `apply`, use the standard cordis API: `ctx.on(event, listener)` to observe events (see cordis_inspect what:\"events\"), or call `harness.registerTool(ctx, harness.defineTool({ name, description, parameters: { text: { type: 'string', required: true } }, output: { schema: { type: 'string' }, render(_args, value) { return [{ type: 'text', text: value }] } }, async execute(args) { return args.text } }))` to give yourself a new tool — it becomes callable on your NEXT step. Tool parameters: each key IS a property — { type: 'string'|'number'|'integer'|'boolean'|'null'|'object'|'array'|'json', required?: true, description?, enum?, const?, items?, properties? }; every direct DSL object declares additionalProperties: true|false, and oneOf: [schema, schema, ...] replaces type for an exact-one union. A raw JSON-Schema { type: 'object', properties, required?: […] } wrapper is also accepted with open-by-default objects. A tool's `execute` MUST return the lossless JSON value declared by `output.schema`; `output.render(args, value)` separately returns Native/model content blocks.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Your working directory is /tmp/advanced-headless.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

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

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

Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

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

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

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

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion.

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

Your working directory is /tmp/advanced-headless.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\nTrack every background task id you start.

Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.\n\nUse the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results.

Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

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

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn. The workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result. Script-body hooks: - `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly. - `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages. - `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`. - `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim. Misused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`. Constraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

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

Your working directory is {{cwd}}.\n\nVerify your work by running the code or tests. Keep answers brief and factual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files.

Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true.

Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.\n\n## Writing code for run_code\n\nPass `run_code` the body of an async TypeScript function (erasable syntax only — no `enum` or namespaces; type annotations are advisory, the code runs type-stripped). Inside the program:\n\n- Call tools as `await tools.name(args)` — quoted access for exotic names: `tools[\"my-tool\"](args)`. Every call resolves to the tool's typed canonical JSON value. Tool arguments must be lossless JSON.\n- A FAILED tool call rejects with `ToolCallError`, whose `toolName` identifies the failed tool and whose `message` is human-readable — `try/catch` it to handle and continue.\n- Independent read-only calls MAY overlap under `Promise.all` (safe calls run concurrently; mutating calls run alone, in submission order). Sequence dependent work with `await`.\n- Emit results with `return` and/or `console.log(...)`. ONLY what you print or return comes back to you — intermediate tool results never enter the conversation, so extract just what you need.\n\nThe available tools:\n\n```ts\ntype JsonValue = null | boolean | number | string | JsonValue[] | { [key: string]: JsonValue }\n\ninterface ToolArgsMap {\n  /** Execute a bash command (`bash -c`) and return its stdout/stderr.

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

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

Track every terminal session id and close sessions that no longer matter. An inferred_idle or timeout result does not prove the foreground command exited.\n\nTrack every background task id you start.

For one or two delegations, prefer plain subagent calls.\n\nUse the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution.

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

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

-# tui-agent
-
-English | [中文](README.zh.md)
-
-The full-screen interactive coding agent: DeepSeek V4, local bash and filesystem tools, compaction, subagents, workflows and fresh-agent Ralph iteration, plan mode (`/plan` enters and `exit_plan_mode` reviews the exit), timeout/spill policy, and JSONL persistence through [`@deepseek-ai/dsh-tui-demo`](../../packages/examples/tui-demo), loaded from `cordis.yml`. The sibling [`headless-agent`](../headless-agent/README.md) runs the same capability class as a one-shot pipe-friendly task, and [`acp-agent`](../acp-agent/README.md) serves it over JSON-RPC.
-
-## Run it
-
-```sh
-# repo root .env (gitignored) or exported env:
-#   DEEPSEEK_API_KEY=sk-…
-#   DEEPSEEK_BASE_URL=https://…   # optional; defaults to the public API
-pnpm run demo:tui
-```
-
-Both the demo script and the installable `dsh` CLI ([`apps/cli`](../../apps/cli/README.md)) boot this example's `cordis.yml` as the shipped default config; `dsh` additionally applies the personal overlay from `~/.dsh` and uses the invoking directory as the workspace.
-
-Type a coding task. The agent works through the `read`/`write`/`edit` filesystem tools for ordinary file operations and `bash` (+ the generic `task_output` / `task_list` / `task_kill` for background tasks) for shell commands, searches, and test runs, each in a fresh `bash -c` (the system prompt tells the model to pass `workdir` instead of `cd`). Both the fs tools and bash resolve relative paths against the session workspace. It can also delegate with `subagent`/`subagent_fork`.
-
-The `todo_write` task tracker is opt-in and not in the shipped config: add `@deepseek-ai/dsh-tool-todo` to `cordis.yml` (or a personal-config overlay under `~/.dsh`) to expose it. Once loaded, the model records a whole-list plan to the session log and the TUI renders it.
-
-The TUI renders Markdown history, reasoning, tool-owned terminal/diff/generic cards, token totals, and — when `todo_write` is loaded — the latest plan. Long tool bodies keep a head/tail preview; Ctrl+O expands or collapses every card. Enter submits or steers while the agent runs, Ctrl+R toggles reasoning, Escape cancels, and `/help` lists commands. `/plan` selects plan mode for the next step; `/plan ` also submits the message into that step, while `/plan off` selects the default mode without model input. `/status` expands the current session's identity, activity counts, exact token/cache buckets, context use, and timestamps without interrupting a running turn. `/model` opens a keyboard selector for the current provider catalog; use Up/Down to focus a model, Shift+Tab to cycle its advertised reasoning efforts, and Enter to select, or use `/model ` and `/model /` for direct selection. `ask_user_question` opens a wide bottom-left keyboard panel with batch progress and numbered options.
-
-### Resuming a prior session
-
-Each run starts a fresh session by default (its event log lands under `./.sessions/`). To **continue** a previous conversation, pass its id to the installed `dsh` CLI — the `main` agent then rehydrates the persisted log instead of starting fresh, so the model sees the earlier turns as history:
-
-```sh
-dsh --resume 
-```
-
-`/resume` opens a searchable keyboard selector with titles, activity, last-turn results, model route, durable goal phase, and live/persisted state. The installed `dsh` host flushes and disposes the current app, then replaces the process with `dsh --resume `. The TUI still prints that command on exit and shows it when a custom host cannot hand off. `dsh --resume ` provides the id on the boot context, which `cordis.yml` reads (`resumeSessionId: !!js "typeof resumeSessionId === 'string' ? resumeSessionId : undefined"`); with no flag the agent starts a new session. A missing or unreadable id starts no agent and emits `agent-loop/config-start-failed`: the TUI prints the failure and exits nonzero. The selector has no cross-process session lock, so deployments with concurrent hosts must coordinate session ownership separately.
-
-## Code Mode
-
-[`code-mode.cordis.yml`](code-mode.cordis.yml) overlays the same tree with the worker-thread runtime and `tools: { mode: code }`. The model receives one `run_code` transport plus a generated TypeScript SDK for the visible tools; only program output returns to model context. Use `mode: both` to expose native calls alongside `run_code`. See the [Code Mode Agent Note](../../.agents/notes/implemented/feature/2026-06-15-code-mode.md) for the execution contract.
-
-```sh
-pnpm run demo:code-mode        # this overlay under the TUI (default UI)
-pnpm run demo:code-mode acp    # the acp-agent example's same-shaped overlay
-```
-
-Try a task that spans several tool calls, e.g.:
-
-> Count the lines of every `*.md` file under docs/ and write the three largest to summary.txt.
-
-and watch the transcript: one `run_code` call, a program looping over tools, and a result the model curated instead of five round-trips of raw tool output.
-
-## What each leaf entry demonstrates
-
-This example is a thin leaf `cordis.yml`: it picks the swappable backends, loads one app package, and adds product tools that are intentionally outside the shared spine. The spine (sessions, system-prompt, tools, agents, invariants, `agent-loop`) and the front-door cluster (JSONL persistence, the pi-tui channel, the pre-created `main` agent) live inside the [`@deepseek-ai/dsh-tui-demo`](../../packages/examples/tui-demo) app and the [`@deepseek-ai/dsh-agent-spine-demo`](../../packages/examples/agent-spine-demo) bundle it loads; the leaf wires the backends and model-facing optional tools:
-
-| Entry | Demonstrates |
-|---|---|
-| `hmr` (`@cordisjs/plugin-hmr`) | the dev/demo edit-reload loop — a **leaf** entry (not baked into the app) because it depends on the Loader's internal module access |
-| `llm-deepseek` | the default native adapter |
-| `bash` (`dsh-bash-local`) | the executor implementation — the swappable half of the bash seam. The model-facing `bash` schema (`tool-bash`) and generic `task_*` controls (`tool-tasks`) come from `dsh-agent-spine-demo`, so only the executor is a leaf choice |
-| `tui-agent` (`@deepseek-ai/dsh-tui-demo`) | the app bundle: the agent-spine demo + JSONL persistence + the pi-tui channel + a pre-created `main` agent |
-| `subagent`, `subagent-spawn`, `subagent-fork` | the subagent provider registry plus the two in-process backends: a fresh child and a child seeded with the parent's completed-turn prefix |
-| `tool-subagent`, `tool-subagent-fork` | two model-facing `dsh-tool-subagent` loads, each bound to a different provider and exposed under a distinct tool name (`subagent`, `subagent_fork`) |
-| `workflow-workerthread`, `tool-workflow` | the worker-thread workflow engine and its model-facing `workflow` tool, with child calls routed through the spawn backend |
-| `plan-mode` | the plugin-owned `/plan [message]` entry and `/plan off` exit commands, plan-mode prompt policy, tool restrictions, and reviewed `exit_plan_mode` transition |
-| `fs-local`, `fs-policy`, `tool-fs` | the filesystem stack: the local `ctx.fs` provider, the read-before-write/edit policy gate (on the `fs/*` event gate), and the model-facing `read`/`write`/`edit` tools. Relative paths resolve against the session workspace |
-
-## End-to-end tests (`pnpm run test:e2e`)
-
-The UI-independent with-key suites assemble the full stack programmatically through `tests/harness.ts` (no PTY, no Loader):
-
-- `tests/full-loop.e2e.ts` — the canary: real model runs `echo e2e-ok` through the real bash tool; asserts `tool/call`/`tool/result` session events and the final answer.
-- `tests/coding-task.e2e.ts` — the swebench-style smoke: a temp dir holds `add.js` (with `a - b` where `a + b` belongs) and a failing `add.test.js`; the agent must fix the bug and verify. The test re-runs `node add.test.js` ITSELF and inspects the files — agent claims are not trusted.
-- `tests/resume.e2e.ts` — durable continuity across processes: run 1 tells the real model a secret code and persists the turn to a temp JSONL root, then the whole context is disposed; run 2 is a fresh context over the same root that RESUMES the session id and asks the model to recall the code. The recall can only come from the rehydrated log.
-- `tests/compaction.e2e.ts` — the compaction smoke: a real multi-step bash task runs with a deliberately tiny context window so the auto-compaction listener fires MID-SESSION. Verifies the WORLD — a `compact/start…end` pair landed in the real log, the surface shrank (a replace node shadowed older nodes), and the agent still produced a correct final answer after compaction.
-- `tests/todo-write.e2e.ts` — loads the opt-in `todo_write` tool, then a real model drives it and the test verifies the resulting `todo/write` session event.
-- `tests/code-mode.e2e.ts` — the with-key Code Mode proof: a real model, a two-tool task, asserting the wire tool list was exactly `[run_code]`, the `tool/code-dispatch` events landed under the parent call, and the curated answer came back.
-
-These self-skip without `DEEPSEEK_API_KEY`. The keyless `tests/tui-keyless-smoke.e2e.ts` boots the real Loader tree in a PTY (the one sanctioned PTY surface): the base boot + `/plan` + `/exit`, a scripted-LLM conversation with a question dialog and tool round-trip, the Code Mode overlay welcome line, and the resume-failure exit path.
-
-## Snapshot tests
-
-`tests/snapshots//session.jsonl` supplies recorded user prompts and model chunks; sibling child logs drive subagents and workflows. The keyless suite executes those scripts through the real loop and tool implementations, then compares readable expected terminal cell/style output. Use `pnpm run test:snapshot:refresh` for presentation-only changes and `pnpm run test:snapshot:record` with a DeepSeek key when a recorded model journey changes. The implemented [TUI snapshot Agent Note](../../.agents/notes/implemented/testing/2026-07-18-tui-terminal-state-snapshots.md) owns the scenario matrix and the split between recorded journeys, transient package snapshots, and PTY coverage.

-
-[English](README.md) | 中文
-
-全屏交互式编码 agent（智能体）：DeepSeek V4、本地 bash 与文件系统工具、压缩（compaction）、subagent、工作流与新 agent Ralph 迭代、plan mode（`/plan` 进入，`exit_plan_mode` 评审退出）、超时／溢出策略，以及通过 [`@deepseek-ai/dsh-tui-demo`](../../packages/examples/tui-demo) 提供的 JSONL 持久化；该应用从 `cordis.yml` 加载。同级 [`headless-agent`](../headless-agent/README.md) 以适合单次管道的任务形式运行同一能力类，[`acp-agent`](../acp-agent/README.md) 则通过 JSON-RPC 提供该能力。
-
-## 运行
-
-```sh
-# repo root .env (gitignored) or exported env:
-#   DEEPSEEK_API_KEY=sk-…
-#   DEEPSEEK_BASE_URL=https://…   # optional; defaults to the public API
-pnpm run demo:tui
-```
-
-演示脚本和可安装的 `dsh` CLI（[`apps/cli`](../../apps/cli/README.md)）都会作为已交付的默认配置启动此示例的 `cordis.yml`；`dsh` 还会应用 `~/.dsh` 中的个人覆盖，并将调用目录作为 workspace。
-
-输入一项编码任务。agent 使用 `read`/`write`/`edit` 文件系统工具处理常规文件操作，使用 `bash`（加上面向后台任务的通用 `task_output`/`task_list`/`task_kill`）执行 shell 命令、搜索和测试。每次操作都在新的 `bash -c` 中运行（系统提示词要求模型传递 `workdir`，而不是使用 `cd`）。fs 工具和 bash 都会根据会话 workspace 解析相对路径。agent 还可以通过 `subagent`/`subagent_fork` 委托。
-
-`todo_write` 任务跟踪器是选用的，不在已交付配置中：请将 `@deepseek-ai/dsh-tool-todo` 添加到 `cordis.yml`（或在 `~/.dsh` 下使用个人配置覆盖）以公开该工具。加载后，模型会把整表计划记录到会话日志，TUI 则渲染它。
-
-TUI 渲染 Markdown 历史、推理、工具所有的终端／diff／通用卡片、token 总量，以及加载 `todo_write` 时的最新计划。较长的工具正文保留首尾预览；Ctrl+O 展开或折叠所有卡片。Enter 用于提交，或在 agent 运行时进行 steering（中途引导）；Ctrl+R 切换推理，Escape 取消，`/help` 列出命令。`/plan` 为下一步骤选择 plan mode；`/plan ` 还会将消息提交到该步骤，`/plan off` 则在没有模型输入的情况下选择默认 mode。`/status` 会展开当前会话的标识、活动计数、精确 token／缓存 bucket、上下文用量和时间戳，而不中断正在运行的轮次。`/model` 打开当前提供方目录的键盘选择器；使用 Up/Down 聚焦模型，使用 Shift+Tab 循环切换为该模型公布的推理强度，再用 Enter 选择；也可以使用 `/model ` 和 `/model /` 直接选择。`ask_user_question` 会打开一个位于左下方的宽键盘面板，包含批次进度和编号选项。
-
-### 恢复早先的会话
-
-每次运行默认都会启动新会话（其事件日志落在 `./.sessions/` 下）。如需 **继续** 先前对话，请将其 id 传给已安装的 `dsh` CLI：此时 `main` agent 会重新水化持久日志，而不会从头开始，因此模型会将早先轮次视为历史：
-
-```sh
-dsh --resume 
-```
-
-`/resume` 打开可搜索键盘选择器，显示标题、活动、上一轮结果、模型路由、持久 goal 阶段和实时／已持久化状态。已安装的 `dsh` 宿主会刷新并释放当前应用，然后以 `dsh --resume ` 替换进程。TUI 仍会在退出时打印该命令，并在自定义宿主无法移交时显示它。`dsh --resume ` 在启动上下文中提供 id，`cordis.yml` 会读取它（`resumeSessionId: !!js "typeof resumeSessionId === 'string' ? resumeSessionId : undefined"`）；没有标志时，agent 会开始新会话。缺失或无法读取的 id 不会启动 agent，而会发出 `agent-loop/config-start-failed`：TUI 打印失败并以非零状态退出。选择器没有跨进程会话锁，因此拥有并发宿主的部署必须自行协调会话所有权。
-
-## Code Mode
-
-[`code-mode.cordis.yml`](code-mode.cordis.yml) 在同一树上覆盖 worker 线程运行时和 `tools: { mode: code }`。模型会收到一个 `run_code` 传输工具，加上一份为可见工具生成的 TypeScript SDK；只有程序输出会返回模型上下文。使用 `mode: both` 可在 `run_code` 旁同时公开原生调用。执行契约详见 [Code Mode Agent Note](../../.agents/notes/implemented/feature/2026-06-15-code-mode.md)。
-
-```sh
-pnpm run demo:code-mode        # this overlay under the TUI (default UI)
-pnpm run demo:code-mode acp    # the acp-agent example's same-shaped overlay
-```
-
-尝试一项横跨多个工具调用的任务，例如：
-
-> 统计 docs/ 下每个 `*.md` 文件的行数，并将最大的三个写入 summary.txt。
-
-然后观察 transcript（文本记录）：一次 `run_code` 调用、一个循环调用工具的程序，以及模型筛选后的结果，而不是五次原始工具输出往返。
-
-## 每个叶节点配置项所演示的内容
-
-此示例是轻量叶节点 `cordis.yml`：它选择可替换后端、加载一个应用包（package），并添加有意放在共享主干外的产品工具。主干（会话、系统提示词、工具、agent、不变式、`agent-loop`）和入口集群（JSONL 持久化、pi-tui 通道、预创建的 `main` agent）位于 [`@deepseek-ai/dsh-tui-demo`](../../packages/examples/tui-demo) 应用及其加载的 [`@deepseek-ai/dsh-agent-spine-demo`](../../packages/examples/agent-spine-demo) 组合包中；叶节点负责接线后端与面向模型的可选工具：
-
-| 配置项 | 演示内容 |
-|---|---|
-| `hmr` (`@cordisjs/plugin-hmr`) | 开发／演示的编辑-重载循环：它是 **叶节点** 配置项（不内置到应用），因为它依赖 Loader 的内部模块访问 |
-| `llm-deepseek` | 默认原生适配器 |
-| `bash` (`dsh-bash-local`) | 执行器实现：bash seam 的可替换一半。面向模型的 `bash` schema（`tool-bash`）和通用 `task_*` 控制（`tool-tasks`）由 `dsh-agent-spine-demo` 提供，因此叶节点只选择执行器 |
-| `tui-agent` (`@deepseek-ai/dsh-tui-demo`) | 应用组合包：agent-spine 演示 + JSONL 持久化 + pi-tui 通道 + 预创建的 `main` agent |
-| `subagent`, `subagent-spawn`, `subagent-fork` | subagent 提供方注册表加两个进程内后端：新子 agent，以及用父 agent 已完成轮次前缀播种的子 agent |
-| `tool-subagent`, `tool-subagent-fork` | 两次面向模型的 `dsh-tool-subagent` 加载，每次绑定不同提供方，并以不同工具名（`subagent`、`subagent_fork`）公开 |
-| `workflow-workerthread`, `tool-workflow` | worker 线程工作流引擎及其面向模型的 `workflow` 工具，子调用通过 spawn 后端路由 |
-| `plan-mode` | 插件拥有的 `/plan [message]` 进入命令和 `/plan off` 退出命令、plan-mode 提示词策略、工具限制，以及经评审的 `exit_plan_mode` 转换 |
-| `fs-local`, `fs-policy`, `tool-fs` | 文件系统栈：本地 `ctx.fs` 提供方、先读后写／编辑策略门禁（位于 `fs/*` 事件门禁），以及面向模型的 `read`/`write`/`edit` 工具。相对路径根据会话 workspace 解析 |
-
-## 端到端测试（`pnpm run test:e2e`）
-
-与 UI 无关的带密钥套件通过 `tests/harness.ts` 以程序方式组装完整栈（无 PTY、无 Loader）：
-
-- `tests/full-loop.e2e.ts`：canary 测试：真实模型通过真实 bash 工具运行 `echo e2e-ok`；断言 `tool/call`/`tool/result` 会话事件和最终答案。
-- `tests/coding-task.e2e.ts`：类 swebench 冒烟测试：临时目录包含 `add.js`（其中 `a - b` 写在本应是 `a + b` 的位置）和失败的 `add.test.js`；agent 必须修复错误并验证。测试会自行重新运行 `node add.test.js` 并检查文件，不信任 agent 的声称。
-- `tests/resume.e2e.ts`：跨进程持久连续性：第一次运行告诉真实模型一个密码并将轮次持久化到临时 JSONL 根目录，然后释放整个上下文；第二次运行在同一根目录上创建新上下文，恢复会话 id 并要求模型回忆密码。只有重新水化的日志能够提供该回忆。
-- `tests/compaction.e2e.ts`：压缩冒烟测试：一项真实多步 bash 任务在故意设得很小的上下文窗口中运行，使自动压缩监听器在会话中途触发。测试验证外部状态：真实日志中出现 `compact/start…end` 对，表层缩减（替换节点遮蔽旧节点），且 agent 在压缩后仍给出正确最终答案。
-- `tests/todo-write.e2e.ts`：加载选用 `todo_write` 工具，由真实模型驱动，测试验证产生的 `todo/write` 会话事件。
-- `tests/code-mode.e2e.ts`：带密钥 Code Mode 证明：使用真实模型和双工具任务，断言线上工具列表精确为 `[run_code]`，`tool/code-dispatch` 事件位于父调用下，且筛选后的答案已返回。
-
-这些测试在没有 `DEEPSEEK_API_KEY` 时自行跳过。无密钥 `tests/tui-keyless-smoke.e2e.ts` 通过 PTY 启动真实 Loader 树（唯一获准的 PTY 界面）：基础启动 + `/plan` + `/exit`，一次带问题对话框和工具往返的脚本 LLM 对话，Code Mode 覆盖欢迎行，以及恢复失败退出路径。
-
-## 快照测试
-
-`tests/snapshots//session.jsonl` 提供已录制的用户提示词和模型分片；同级子日志驱动 subagent 和工作流。无密钥套件通过真实循环和工具实现执行这些脚本，然后比较可读的预期终端单元格／样式输出。使用 `pnpm run test:snapshot:refresh` 刷新仅展示变更；已录制模型旅程改变时，使用 DeepSeek 密钥运行 `pnpm run test:snapshot:record`。已实现的 [TUI 快照 Agent Note](../../.agents/notes/implemented/testing/2026-07-18-tui-terminal-state-snapshots.md) 拥有场景矩阵，以及已录制旅程、瞬时包快照与 PTY 覆盖之间的分工。

-    section: |
-          You are in plan mode. Stay in plan mode until exit_plan_mode succeeds or the user switches the session mode. Imperative language to implement changes means plan the implementation, not execute it. A user's conversational agreement — including an answer confirming something you asked — approves nothing and does not end plan mode; fold the confirmed decision into the plan and submit it through exit_plan_mode.
-
-          Explore first. Use non-mutating reads, searches, static analysis, and checks to ground the plan in the actual repository. Do not edit or write files, change configuration, run formatters or code generation that rewrites tracked files, commit, or otherwise carry out the plan. Prefer existing functions and patterns over new machinery.
-
-          The tool catalog stays the same across modes for request-cache stability. These plan-mode rules override any later tool description or guidance that suggests using mutation tools; those tools remain listed only to keep the request shape stable. Do not use todo_write to track this planning phase: it tracks implementation after an approved plan, while the plan itself belongs in exit_plan_mode.
-
-          Resolve discoverable facts by inspection. Use ask_user_question only for user-owned choices or material ambiguity that inspection cannot answer. Do not ask the user where code lives or how current behavior works when you can find out.
-
-          Make the plan decision-complete: state the goal and success criteria; group implementation changes by subsystem; identify public API, schema, and data-flow changes; cover edge cases, failure modes, tests, acceptance criteria, and explicit assumptions. Keep it concise enough to review but detailed enough that another engineer can implement it without making design decisions.
-
-          When ready, call exit_plan_mode with the complete plan markdown, starting with a # title. Make exit_plan_mode the only and final tool call in that assistant response: it presents the plan for approval, and implementation begins only in a later step after approval. Do not paste the final plan as a plain reply or ask "should I proceed?" through prose or ask_user_question. If review rejects it, incorporate the feedback and present again. If the review channel is unavailable or aborted, stay in plan mode and ask the user to switch modes manually; do not proceed with implementation.

 - **在受管进程组之上应用配置预算**：`resolve()` 从配置补全 `workdir`／`timeoutMs`／`stdoutMaxBytes`，每次 spawn 都向服务传入显式的字节上限、spill 上限与 `graceMs`（默认 3 秒，沿用 OpenCode 的升级策略）。进程组终止、退出后的管道排空宽限期、尾部保留截断与有界 spill 文件是 [`dsh-subprocess-local`](../../subprocess/subprocess-local/README.md) 的机制。前台 `BashExecRequest.stdoutMaxBytes` 可为某个受信任调用方提高单次 stdout 捕获预算；stderr 和后台运行仍使用 `maxOutputBytes`。

+# client/ — web-GUI browser half
+
+English | [中文](README.zh.md)
+
+The browser side of the dsh web GUI: shell kernel, module system, wire consumer, React-free object services, the slot system, and the `ui-*` feature-plugin roster. Authoring rules live in [AGENTS.md](AGENTS.md); the host half is [`host/`](../host/README.md). All **product** packages, named `@deepseek-ai/dsh-client-`.
+
+| Package | Role | ctx key / slot |
+|---|---|---|
+| `web/` | Shell kernel: `AppWebEntry` runs the two-stage boot over the host-pushed entry graph | (boots the tree) |
+| `modules/` | Client module system: browser peer of Node's ESM loader as a lazy CJS table under the vendored cordis Loader | (module face) |
+| `web-react/` | Shell-side React glue: `createSlotRenderer` + `SessionProvider` render seats | (renderer install) |
+| `connection/` | Wire consumer both ends: browser `ctx.connection` (shared api client + stream loop) and the node half mounting the `/api` route with its browser-trust fence | `ctx.connection` |
+| `runtime/` | Client cordis boot and React-free object services: slots, Sessions, Workspaces, per-session bindings | `ctx.slots` `ctx.sessions` `ctx.workspaces` |
+| `hmr/` | Dev-only hot reload for fetch-arrival client plugins (`--dev` graphs) | (dev entry) |
+| `locale/` | Browser locale preference (`zh`/`en`) plus the ns×locale dictionary registry | `ctx.locale` |
+| `ui-slots/` | Slot registry pure core: SlotMap merging, single `register` API, the four-share props family | (types + core) |
+| `ui-theme/` | Theme preference over the `--dsw-*` token stylesheets (`light`/`dark`/`system`) | `ctx.theme` |
+| `ui-primitives/` | Pure React atoms: icons, Button/Pill/Menu/Modal/Input, markdown family | (component library) |
+| `ui-layout/` | Shell three-column AppFrame; declares `sidebar` / `conversation` / `details` / `conversation.empty` | `ctx.layout` |
+| `ui-sidebar/` | Sidebar shell: Workspace/session rail, search, collapse; declares `sidebar.workspaces` | (slot host) |
+| `ui-workspace/` | Shared Workspace picker: browser region + hero picker over the same creation flow | (fills `sidebar.workspaces`, `conversation.hero.workspace`) |
+| `ui-conversation/` | Conversation domain: skeleton, chat view, input dock, per-tool row slots | (slot host) |
+| `ui-trajectory/` | Trajectory/Waterfall view tabs; the minimal pure-consumer plugin exemplar | (fills `conversation.view`) |
+| `ui-command/` | Command surface: session-keyed directory cache, `/` source, three-kind dispatch | `ctx.command` |
+| `ui-slash/` | Input trigger pipeline: `/` and `@` detection, grouped candidate menu, source roster | `ctx.slash` |
+| `ui-skill/` | `/`-trigger skill reference source over the `skill.list` RPC | (registers into `ctx.slash`) |
+| `ui-subagent/` | `@`-trigger subagent reference source over the sessions snapshot | (registers into `ctx.slash`) |
+| `ui-model/` | Model selection: `/model` popupSelect + the composer model seat over `ModelService` | `ctx.models` |
+| `ui-question/` | Web `ask_user_question`: host half mounts the tool, browser half fills the composer seat | (fills `conversation.composer`) |
+| `ui-settings/` | Settings shell: trigger chrome + modal panel; declares the `settings.*` slots | (slot host) |
+| `ui-settings-general/` | Settings ownerless copy: chrome content + General section skeleton | (fills `settings.*`) |
+| `ui-models/` | Models settings nav entry (content column lands in a later phase) | (fills `settings.section`) |
+
+Feature UI composes only through the slot system (`ctx.slots.register`) — the [slot system standard](../../.agents/notes/implemented/architecture/2026-07-22-slot-type-chain-implementation.md) is the definitive model; the [web client architecture note](../../.agents/notes/implemented/architecture/2026-07-19-gui-web-client-architecture.md) owns the loading chain and object layer.

 Wire consumer layer: the client plugin's apply mounts `ctx.connection` (shared api client + single-consumer stream-loop starter); the export face carries the wire contract types, the `AbstractApiClient` seam, and the loop's sink/config types. The platform subclasses (WebApiClient/FixtureApiClient), the ConnectionController loop, and the fixture data source are package-internal — apply selects and drives them; tests reach them via src. Contract: api-contracts v3 §3.
 
+## /api browser-trust fence
+
+The node half guards every request under `/api` before bridging (`src/api-request-trust.ts`). Every request — browser-marked or not — must present a `Host` that is a loopback authority or matches a `trustedHosts` entry: exact on `host:port` entries, any port on port-less entries, both sides compared through WHATWG normalization (DNS-rebinding defense). There is deliberately no shortcut for requests without browser markers: over plain HTTP a browser attaches neither `Origin` nor Fetch-Metadata to reads (EventSource, images, navigations — those headers go only to trustworthy destinations), so an unmarked request may still be a rebound browser read with a readable response, and Host is the one header rebinding cannot forge; non-browser clients pass the same fence via loopback, the CLI-derived LAN IP literals, or a declared authority. When markers are present, an attached `Origin` must equal the Host authority, and an explicit `sec-fetch-site: cross-site` marker is refused. A `trustedHosts` entry that is not a bare, canonical `host[:port]` authority — one WHATWG parsing reads back exactly as written — fails the plugin load loudly: parsing would otherwise quietly authorize the hostname inside `harness.internal/path`, or broaden a dangling-colon or zero-padded port to an any-port grant. Failures answer plain 403 before any RPC dispatch. A non-loopback (`--host 0.0.0.0`) deployment therefore needs its serving authorities trusted: the dsh CLI derives the machine's LAN IP literals itself and its `--trusted-host` flag declares named ones, so `trustedHosts` in cordis.yml is for compositions the CLI does not boot. The fence is deliberately not an authentication layer — reachability policy stays with the webserver binding, and auth remains deferred work. Decision record: [the api browser-trust boundary Agent Note](../../../.agents/notes/implemented/architecture/2026-07-28-api-browser-trust-boundary.md).

 ## Keyless fixture
 
 Any `fixture` query parameter selects the in-memory carrier. `fixture=empty` starts with no Workspace or Session; `fixturePrompt=reject` rejects prompts before acceptance; `fixtureAttach=fail` publishes a Session but rejects its Workspace attachment; `fixtureSessionCreate=drop-response` publishes and frames a Session before dropping the create response; and `fixtureFrames=workspace-first` reverses the default session-first create-frame order. Workspace creation by name/path and caller-preallocated SessionIds remain deterministic enough for assembled Web tests to reconcile list and frame arrival.

 协议消费层：客户端插件的 apply 会挂载 `ctx.connection`（共享 API 客户端 + 单消费方流循环启动器）；导出表层携带协议契约类型、`AbstractApiClient` seam，以及循环的 sink／配置类型。平台子类（WebApiClient/FixtureApiClient）、ConnectionController 循环和 fixture 数据源都属于包内部：apply 负责选择并驱动它们，测试则通过 src 访问。契约：api-contracts v3 §3。
 
+## /api 浏览器信任栅栏
+
+node 半侧在桥接前守卫 `/api` 下的每个请求（`src/api-request-trust.ts`）。每个请求——无论是否带浏览器标记——`Host` 都必须是回环地址权威，或与某个 `trustedHosts` 条目匹配：带端口的 `host:port` 条目精确匹配，不带端口的条目匹配任意端口，两侧均经 WHATWG 归一化后比较（DNS rebinding 防御）。刻意不为无浏览器标记的请求开捷径：明文 HTTP 下浏览器的读取（EventSource、图片、导航——这些头只发给可信目标）既不带 `Origin` 也不带 Fetch-Metadata，因此无标记请求仍可能是被重绑页面发起的、响应可被读走的读取，而 Host 是重绑唯一伪造不了的请求头；非浏览器客户端经由回环地址、CLI 推导的 LAN IP 字面量或已声明的权威通过同一道栅栏。当标记存在时，`Origin` 必须与 Host 权威完全一致；显式的 `sec-fetch-site: cross-site` 标记一律拒绝。不是纯的、规范形 `host[:port]` 权威的 `trustedHosts` 条目——即 WHATWG 解析读回后与原文不完全一致的——会让插件加载大声失败：否则解析会悄悄授权 `harness.internal/path` 这类笔误里的 hostname，或把悬空冒号、补零端口放大成任意端口授权。失败在任何 RPC 分发之前以纯 403 应答。因此非回环（`--host 0.0.0.0`）部署需要让自己的服务权威被信任：dsh CLI 会自行推导本机的 LAN IP 字面量，其 `--trusted-host` flag 用于声明具名权威，所以 cordis.yml 中的 `trustedHosts` 面向 CLI 不参与引导的组合。这道栅栏刻意不承担认证职责——可达性策略归 webserver 绑定配置，认证仍是延期工作。决策记录：[api 浏览器信任边界 Agent Note](../../../.agents/notes/implemented/architecture/2026-07-28-api-browser-trust-boundary.md)。

 ## 无密钥 fixture
 
 任何 `fixture` 查询参数都会选择内存载体。`fixture=empty` 启动时不含 Workspace 或 Session；`fixturePrompt=reject` 在接受前拒绝提示词；`fixtureAttach=fail` 发布 Session 但拒绝将其附加到 Workspace；`fixtureSessionCreate=drop-response` 在丢弃创建响应前发布 Session 并为其发出帧；`fixtureFrames=workspace-first` 则反转默认的 Session 优先创建帧顺序。按名称／路径创建 Workspace 以及由调用方预先分配 SessionId，均具有足够的确定性，组装后的 Web 测试可以据此协调列表与帧的到达。
