 A fresh registry-assigned Symbol provides collision-free execution identity without a WeakSet membership registry. Callers cannot supply the execution's own token through `ToolExecutionInput`; they only receive the pipeline-owned `ToolExecution` after the registry creates it.

 After post-execute or outer pipeline normalization, the registry losslessly snapshots the candidate result, converting a snapshot failure into an ordinary error, invokes the call's snapshotted optional `ToolDefinition.finalizeContent` callback, then materializes and freezes the accepted final result once. The callback may replace only content, so structured error identity, contexts, and metadata remain registry-owned even when a tool enforces a last-mile result bound. Every synchronous `tools/result` observer receives that exact committed object, and observer failures are contained individually.

 There is no component registration model besides slots — the former view and tool rings both dissolved into it. Conversation views are entries of the `'conversation.view'` list slot ui-conversation declares, tab metadata rides the registration options (`id`/`order`/`label`), and per-view chrome lives inside the view components themselves. Final Chat business Nodes dispatch through the keyed/session `'conversation.chat.node'` slot; ui-tool owns its `tool-call` entry, recursively renders the supplied `subCalls`, and declares the keyed/session `'tool.call.toolview'` child slot. The key space stays runtime-open (SlotMap declares slots, never keys), and roots and descendants dispatch by `entryKey: toolName` with `GenericToolCard` as the fallback. Business packages register atomic views through `ctx.slots.inject('tool.call.toolview', () => ctx.slots.register({ name: 'tool.call.toolview', key: '<tool>' }, Row))`; the declaration is the load and reload dependency ([decision](2026-08-05-slot-declaration-injection.md)). ui-conversation separately delegates the selected call's details body through `'conversation.details.tool'`, so ui-tool's card models remain the single presentation owner without making conversation import Tool components. The target-neutral event and view registries are data assembly seams rather than parallel component registries ([decision](2026-08-09-client-conversation-node-assembly.md)).

 ## Problem
 
-Tool bodies previously authored model-facing `ContentBlock[]` directly, optionally wrapping it with opaque `meta`. Native function calling therefore had a usable human projection, but a programmatic caller had no stable domain value: Code Mode flattened the blocks back into a string, dynamic tools repeated the content shape, and policy could replace presentation without any way to distinguish that change from replacing the operation's result. Several capability seams already returned richer provider values only to discard them at their model-facing tool boundary.

Several capability seams already returned richer provider values only to discard them at their model-facing tool boundary.
 
 The durable session contract made that presentation authoritative for replay, but persisting every rich intermediate value would enlarge logs, expose implementation data to compaction and migration, and incorrectly turn an execution-local API into session format. The foundation instead needs one typed value during execution and an explicit projection into the existing durable/model-facing content.

 `tools/post-execute` has two mutually exclusive successful projections. Replacing `content` changes only Native/model presentation and preserves the canonical value and metadata. Replacing `value` revalidates the replacement and recomputes both presentation projections. A block removes the value and becomes a failure. Content replacement is therefore not a confidentiality mechanism: policy that must prevent programmatic access blocks the call or replaces the value.
 
-Canonical values are execution-local. The agent loop persists `tool/result` with only `content`, `error`, and optional `meta`; Code Mode's `tool/code-dispatch` persists the sub-call's rendered `content` and `isError`. Neither event stores the canonical intermediate value, so replay reproduces presentation but cannot reconstruct the programmatic result. When a tool declares `presentationMeta`, it is computed only for a direct surface call; a nested Code dispatch gets no metadata or result card. The outer `run_code` card instead reads final post-policy content and declares no presentation metadata. Generic and tool-owned spill projections similarly skip nested dispatches, whose canonical value never enters model context.

 **Host side — compose the graph.**
 
 1. The composing app (`apps/cli`) ships the roster as ordinary rows in its `cordis.yml` config tree — client plugin packages are entry rows like every host plugin, including the always-mounted `client-hmr` row. A roster row that fails to import is caught by `assertEntriesLoaded`; a row whose fiber rejects is reported with its original stack by `assertEntriesActivated` ([host boot decision](2026-07-24-web-config-tree-boot-and-transport-layering.md)).

The row's three optional fields come from manifests, never hand-copied. Composition orders requested dynamic rows before their consumers, rejects synchronous request cycles, and assigns every row to exactly one initial batch. It refuses declared plugins without built `./client` bundles and groups their package/path rows under one required source-build instruction; malformed declaration fields also fail activation, and the Host audit reports either error from the FAILED fiber.
-3. Scanning is incremental per package — there is no full-rescan code path. Each cordis `internal/plugin` emission marks the fiber's entry name dirty (entry-less fibers drop O(1)); a microtask flush reconciles each dirty name against live loader entries, with package metadata (including the negative "not a client package" verdict) cached per name forever and bundle re-hashing reachable only through `rebuilt(id)`. The activation pass seeds the same dirty set from current entries and flushes synchronously, so first scan and steady state share one implementation. Initial rows receive an opaque process nonce plus sequence without hashing their artifacts; startup combo revisions hash the combined script inputs plus indexed map, and the rows plus batch descriptors hash into `graph.rev`. The graph types are single-sourced in the modules package's `./client` export — the webserver knows nothing about the graph, while modules registers the combo route and contributes structured index-injection rows.
+2. The `dsh-client-modules` node half (the package is dual-face: its browser half is the module table) resolves each live Loader entry through the same `name` and owning-tree `baseUrl` inputs that imported its Host face, then reads the nearest owning package.json `dsh.client` declaration and composes `window.__DSH_BOOT__`: `{ rev, entries: [{ id, url, rev, inject?, immediately?, external? }], batches: [{ phase, url, rev, entries }] }`. The manifest package name is the browser module identity even when an overlay names a relative source or built entry file. Distinct active Loader sources resolving to one package name fail composition; after one source unloads, the surviving source supplies the row without a fiber restart. The row's three optional fields come from manifests, never hand-copied. Composition orders requested dynamic rows before their consumers, rejects synchronous request cycles, and assigns every row to exactly one initial batch. It refuses declared plugins without built `./client` bundles and groups their package/path rows under one required source-build instruction; malformed declaration fields also fail activation, and the Host audit reports either error from the FAILED fiber.

 Why is the roster yml rows and not a scan? Because which plugins compose into a deployment is a composition decision, not a package property — a package declaring `dsh.client` in the repo does not mean this deployment mounts it, so discovery-by-scan cannot make that call; the node half scans only what the tree actually mounted.

The Host retains per-plugin bundle/map snapshots, generated one-resource responses, current startup combo responses, and one previous startup generation, so memory scales as several copies of the composed client artifacts.

 - **Authority fence (dsh-client-connection, `src/api-request-trust.ts`)**: every request must present a `Host` that is loopback or matches a `trustedHosts` entry (exact on `host:port`, any port on port-less entries, WHATWG-normalized; rebinding defense). 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. A `trustedHosts` entry that is not a bare, canonical authority fails the plugin load — WHATWG parsing would otherwise quietly authorize the hostname inside a typo or broaden an exact-port grant. `host.pickDirectory` loses its bespoke guard and rides the same fence.
 
 Reachability is the webserver binding's policy (`host: 127.0.0.1 | 0.0.0.0`), and this fence is a confused-deputy defense rather than identity. Connection applies the separate [browser token authentication](2026-08-24-browser-token-authentication.md) after the fence. The fence does not inspect peer socket addresses: binding expresses reachability, `trustedHosts` names accepted authorities, and the socket address adds nothing the Host/Origin checks need.

 可达性由 webserver 的绑定配置（`host: 127.0.0.1 | 0.0.0.0`）控制，这道栅栏是混淆代理人防御，而不是身份。Connection 在栅栏之后应用独立的[浏览器令牌认证](2026-08-24-browser-token-authentication.zh.md)。栅栏不检查对端 socket 地址：绑定表达可达性，`trustedHosts` 点名接受的 authority，socket 地址提供不了 Host/Origin 校验需要的额外信息。

The gateway (`dsh-host-apiproxy`) injects `directoryPicker`, serves the matching RPCs, and answers `directory-picker-unavailable` for the other kind.

Being the only non-replayable class on the mux stream is what broke it. Host and mux are independent SSE streams with no cross-stream ordering, so a request emitted before a removal could arrive after `host/session-removed` and revive a dead session's telemetry, while a legitimate request for a new lifecycle reusing the same id could be fenced by a late removal. `session/subscribed` is not lifecycle proof — it says a queue began subscribing to an id, not that a new in-memory session replaced an older one — and `lastSeq` is a durable watermark two lifecycles can share. A correct fix required a monotonic lifecycle generation on the frame, on subscription, and on removal, plus a client watermark comparison.

-**Wire domains on the compiled RPC map, rejections as codes, owner events forwarded verbatim.** `settings.describe/openDocument/update/replace/mutate`, `credentials.describe/set/unset`, `llm.providers`, and `llm.models` join `RpcMethodMap`, so the compiler-locked wiring sites keep schema, handler, and client in lockstep. Seam rejections fold into `settings-rejected {ns}` / `credential-rejected {ref}` business errors, while clients subscribe to forwarded settings, credentials, and LLM owner events and converge without polling ([forwarded Remote events](2026-08-10-remote-event-delivery.md)). Connection authenticates settings reads, native actions, writes, `pickDirectory`, `openPath`, and every other Host operation with one browser session; Host/Origin failures still return 403 before identity is checked.
+**Configuration calls use their owning wire implementation, rejections as codes, and owner events forwarded verbatim.** `@deepseek-ai/dsh-api-settings-controller` owns generated Remote methods for `settings/describe`, `settings/update`, `settings/replace`, `settings/mutate`, `settings/openSettingsDocument`, `settings/openAgentPresetDirectory`, and `credentials/describe|set|unset`; `@deepseek-ai/dsh-llm` owns `llm/listProviders`, `llm/listConfigurableProviders`, and `llm/discoverModels`. Provider absence retains the configuration API's actionable `internal` diagnostic, while seam rejections retain `settings-rejected {ns}` / `settings-conflict {ns, expected, actual}` / `credential-rejected {ref}`.

Connection authenticates generated Remote methods and API Proxy fallbacks with the same browser session; Host/Origin failures still return 403 before identity is checked.
 
 **`describe()` grows layers and structural secret redaction.** `SettingsDescriptor` carries `base`/`user` beside the effective value, so the form marks "overridden" by presence in the user layer, not value inequality (an override *equal* to the base is still an override). `describe({ redactSecrets: true })` — mandatory at every wire face — strips `role('secret')` subtrees from all three layers via a pure structural walk of the schema (object/dict/array containers; a secret-role subtree is one opaque leaf) and enumerates the stripped slots as `{path, set}`, so a page can render write-only inputs without ever receiving a value.
 
-**The Host identifies and opens the local settings document.** The settings seam exposes optional `documentPath` provider metadata and a `prepareDocument()` operation; `settings-file` returns its fully resolved custom or `$DSH_HOME/settings.yaml` filename and exclusively creates an absent empty document with owner-only permissions, while non-file providers retain the base `undefined`. The browser-authenticated `settings.describe` response carries only the boolean `hasDocument` capability beside the redacted namespace views. `ui-settings-general` registers a `settings.action` entry only on loopback pages, shows it only after the metadata confirms that a provider-owned local document can be prepared, and invokes pathless `settings.openDocument`; the Host resolves the provider path again before a text-document handoff (`open -t` on macOS so an arbitrary YAML file association cannot redirect the gesture, `xdg-open` on desktop Linux, `Invoke-Item` on Windows, and `wslpath -w` followed by that Windows handoff on WSL). Generic workspace paths retain the default intent, including its browser preference for browser-renderable documents. The browser neither derives `$DSH_HOME` nor receives a filesystem target; non-loopback pages retain the Client policy that makes no Host settings read for this action.

 **Authoring a preset is an RPC, and a privileged one.** A composition is a file, but "edit it on the filesystem" is not a browser affordance, so the roster gained `read`/`write`/`remove` beside `select`. Connection authenticates authoring, `list`, `select`, and the complete Host API with one browser session: a composition names the plugins a session runs, so reading one is reconnaissance and writing one is arbitrary capability, while choosing a preset grants nothing `session.create` with `agentPreset` did not already grant. The capability is not the preset's to grant either: the deployment's own default already carries `bash` and the filesystem tools, so any caller that may start a session at all can already run commands as this process. Containment is a property of the id (`[a-z0-9][a-z0-9-]*`), checked before it becomes a directory name rather than by inspecting the joined path afterwards; the text is parsed with the loader's own schema and dialect, so a save cannot leave a file no session could load. Shipped presets are refused for writes and deletes, because the deployment's copy is what a broken local preset is compared against — which also makes "duplicate, then edit" the authoring path rather than an afterthought.
 
-**A service with a consumer outside the agent plane cannot move into a preset.** The aggressive split moved the `subagents` registry and its spawn/fork backends into the delegation group's entry-local realm, and `dsh web` then failed to boot: `dsh-host-apiproxy` is a HOST row that injects `subagents` to answer the browser's cross-session queries (`listChildren`, `followup`), so it waited forever for a service only sessions now provided. A per-session copy is wrong twice over — a provider name registers once, so the second session would have collided anyway. The registry and every shared backend, including the [fixed Codex and Claude Code product providers](2026-08-10-product-subagent-providers-in-shared-host.md), are host-plane; a preset contributes whichever delegation TOOLS its agent should see, and those tools resolve the host registry. `workflows` stays entry-local because nothing outside an agent reads it. Grepping injectors is what should have caught this and did not: the search has to include the host packages, not just the agent-plane ones.

 **A preset's package names must resolve from the harness, not from the preset.** `EntryTree.import()` resolves a row against its own tree's `baseUrl`, which `Include` sets to the composition's directory. That is right for a relative specifier and fatal for a package name: a locally authored preset lives under the user's home, where Node's upward `node_modules` walk never reaches the installed harness, so every `@deepseek-ai/dsh-*` row fails to import and the whole preset is unmountable. The shipped presets hid this — they sit inside the install. The mount records the host composition's base before plugging the subtree and sends bare specifiers there, leaving relative paths resolving from the preset so its own files still travel with it. The real-composition test writing a preset into a temp root is what found it.

 **The choice belongs to the screen where it still works.** The composer seat spent almost its whole life disabled, since the preset is fixed once a turn has run. It moved to the new-session screen beside the workspace picker, where the pick is *staged*: that screen precedes the session it applies to, and the stage lands when a session becomes current and is still blank — covering both the session a workspace connect creates and the blank one it reuses, which riding `sessions.create` would miss. It is spent on first use, matching the workspace picker beside it. What a running session runs is then a read-only label in its header: a control there would promise a switch the host refuses outright.
 
-**A preset multiplies a cost the host was already paying: nothing disposes an agent.** Measured against the shipped compositions with `--expose-gc`, one live agent holds ~0.17 MB on `minimal` and ~1.31 MB on `standard`/`cordis`, mounting in ~38 ms and ~135 ms; the first agent of a process costs ~7 MB more as Node imports the modules, which every later mount then shares. Growth is strictly linear — 10, 30 and 50 agents give the same per-agent delta — and disposal reclaims essentially all of it (50 `standard` agents held 57.8 MB and returned it). So the object graph does not leak; the lifecycle does. `dsh-host-apiproxy` discards the `AgentHandle` it creates, `archiveSession` only edits the workspace registry, `AgentRegistry` has no eviction, and the sole disposal site in the host is the JSON-RPC server's own shutdown. A web host therefore retains every session it has touched, at ~1.3 MB each once presets are composed rather than ~0.2 MB before. Note that pruning the mount registry does not help here: it drops records whose fiber `uid` has cleared, and an agent that never dies never clears one.

 消除逐 child 扫描的出路有三类：把 mode/label 提升进 header（写路承担）；为投影建持久派生（checkpoint 阶梯，或随查询索引重建落值、读端对账）；读时现算（live 走水位缓存，cold 一次整读）。本记录取第三条。「值随查询索引落库」已整体退役：查询基础设施被迫认识领域词汇，而唯一消费方读时现算即可满足——live child 的零读由 session-projection 既有水位缓存白拿，cold child 的一次整读被「算完即止」显式接受。前两条与退役理由详见考虑过的替代方案一节。
 
 要点：
 
 - **subagent 列表不依赖 session-query**：枚举由 subagent 自管的 live-preferred 合并完成，mode/label 经 `ctx.sessionProjections` 取值；没有 query backend 的部署照常列表。
-- **取值三级「算完即止」阶梯**：live child 读 `sessionProjections.snapshot()`（注册表既有水位缓存，零日志读）；cold child 先读可选 `sessionProjectionCache.cachedSnapshot(header)`，values 含非 null 且过 seq 门（`seq >= seedLength ?? 0`）的 `subagent` 身份即直接用；否则一次 `persistence.inspect` 整读加 `registry.restore({}, events, 0)` 折叠；再没有就没有——不自建缓存、无回写、无索引。
-- **`subagent` projection unit 是折叠规则唯一权威**：live snapshot、cold restore、GUI history 的 detached 折叠全部经 registry 计算，不存在第二份描述符解释逻辑。
+- **取值三级「算完即止」阶梯**：live child 读 `sessionProjections.snapshot(session, ['subagent'])`（注册表既有水位缓存，零日志读）；cold child 先读可选 `sessionProjectionCache.cachedSnapshot(header, ['subagent'])`，非 null 身份通过 seq 门（`seq >= seedLength ?? 0`）即直接使用；否则执行一次完整 Session 观察，再经注册的 `subagent` unit 折叠；再没有就没有——不自建缓存、无回写、无索引。
+- **`subagent` projection unit 是折叠规则唯一权威**：live 与 cold 快照都运行同一份已注册 unit，不存在第二份描述符解释逻辑。
 - **header、描述符（v2）、session-persistence、session-projection(-cache)、session-query(-sqlite) 全部零改动**；存量数据第一次被列表时一次 `inspect` 现算获得精确值，无 unknown 降级态、无迁移。
 
 与既有记录的关系：
 
 - 本记录取代 [durable-subagent-catalog](../feature/2026-07-22-durable-subagent-catalog-and-list-agents.zh.md) 中列表读路径的两项设计：经 `sessionQuery.traceSession` 枚举，与逐 child 读取描述符事件（`listEvents` 加精确 `readEvent` 双读、就地诊断分类）。diagnostic 行语义保留，分类改由列表按投影值缺席与 activity 派生；描述符事件仍是 mode/label 的唯一持久权威与折叠输入，恢复鉴权与激活约定不动。属部分取代，两记录保持交叉链接。
-- [session-projection RFC](../../proposed/architecture/2026-07-27-session-projection-and-command-log.zh.md) 的 registry 约定（`ProjectionDefinition`、`snapshot`、`restore`）零改动，本记录只为其新增 `subagent` 身份 unit 一个注册项，并成为 snapshot（live）与 restore（cold）两处既有读法的又一消费实例——GUI history 的冷读已是同款。折叠规则只在 registry 注册一份；任何消费面都经 registry 计算，不存在第二份折叠逻辑。
+- [session-projection RFC](../../proposed/architecture/2026-07-27-session-projection-and-command-log.zh.md) 是 registry 约定的权威，其后由 [state-and-client-views 记录](2026-08-19-session-projection-state-and-client-views.zh.md)拆分为 host 状态与客户端视图；本记录新增客户端可见的 `subagent` 身份 unit，并经 live 与 cold 快照消费它。折叠规则只在 registry 注册一份；任何消费面都经这一份已注册 unit 计算，不存在第二份折叠逻辑。

 ## Problem
 
-The `headless` product contract is one local task with final assistant text on stdout, a success-sensitive exit code, no listening port, and the stderr reasoning projection owned by [headless reasoning progress](../feature/2026-08-21-headless-reasoning-progress.md). A composition containing Workspace Host services, ApiProxy, HTTP, the Web runtime, or browser plugins contradicts that contract and makes local completion depend on an unrelated transport tree.
+The `headless` product contract is one local task with final assistant text on stdout, a success-sensitive exit code, no listening port, and the stderr reasoning projection owned by [headless reasoning progress](../feature/2026-08-21-headless-reasoning-progress.md). A composition containing Workspace Host services, browser RPC, HTTP, the Web runtime, or browser plugins contradicts that contract and makes local completion depend on an unrelated transport tree.
 
 The direct entry point still needs the same deployment model state as Web-created Agents. A separate provider/model default would give one deployment two answers, while deriving completion before the Agent and Session persistence are quiescent permits stdout and the exit code to observe incomplete state.
 
 ## Decision
 
-The shipped `headless` profile contains `dsh-base` and `dsh-headless`. The base supplies the disabled module-HMR default; the headless bundle supplies its persona and tool mode, mounts the Code Mode worker explicitly, and inserts `headless-runner` without overriding that policy. Its tree contains no `@deepseek-ai/dsh-host-*` package, ApiProxy, HTTP server, Web runtime, or browser client. Code Mode and Session persistence are one-shot Agent capabilities independent of Web presentation.
+The shipped `headless` profile contains `dsh-base` and `dsh-headless`. The base supplies the disabled module-HMR default; the headless bundle supplies its persona and tool mode, mounts the PTC mode worker explicitly, and inserts `headless-runner` without overriding that policy. Its tree contains no browser Connection, HTTP server, Web runtime, or browser client. PTC mode and Session persistence are one-shot Agent capabilities independent of Web presentation.
 
 `headless-runner` is a direct core entry point. After Loader settlement, it reads `ctx.agentDefaultModel.currentSelection()`, creates a fresh persisted Agent through `ctx.agents.create`, installs that `ModelSelection` in the Agent scope, waits for startup quiescence, anchors the Session sequence, submits one ordinary user message, and waits for quiescence again. It awaits `ctx.sessions.flush`, folds its durable event interval for the last non-empty assistant text and final `turn/end` reason, writes the text plus one newline to stdout, and requests bounded launcher shutdown with exit 0 exactly when the reason is `completed`. [Headless reasoning progress](../feature/2026-08-21-headless-reasoning-progress.md) owns the live stderr projection; a terminal `error` reason writes its durable code and message there, and unexpected driver failures also use stderr and exit 1.
 
-`@deepseek-ai/dsh-agent-default-model` owns the transport-independent default used for an Agent without a session-local selection. `AgentDefaultModelConfig` provides `ctx.agentDefaultModel` and registers the `agent-default-model` Settings section. Composition config supplies `{provider, model}`; user settings may also supply `reasoningEffort`. `currentSelection()` returns the live complete selection and `saveSelection()` writes it as a complete section, so a selection without an effort clears any stored effort. `dsh-base` supplies the composition entry. Direct and ApiProxy entry points consume this service; ApiProxy alone owns session-local precedence, model validation, and persistence of accepted Web selections.

Direct creation and Session Controller Remote calls consume this service; the Session Controller owns session-local precedence, model validation, and persistence of accepted Web selections.
 
 `loadProfile` recognizes the exact installation-owned headless tuple (`dsh-base`, `dsh-web-app`, `dsh-headless`) and normalizes it to the shipped headless template while preserving every other manifest field. Extra, missing, or reordered bundle lists are user-owned and remain untouched.

-`dsh --profile headless` provides a local Agent task rather than browser observation, Host APIs, or HTTP. Users who need those capabilities choose `dsh web`. Text-only successful runs leave stderr empty, reasoned runs stream the provider-reported content there, completion follows durable flush, and the persisted Session remains available to later tooling. Its initial user message records `source.kind: 'user'` and therefore carries no ApiProxy `rpcId`.

 直接入口仍需要与 Web 所创建 Agent 相同的部署模型状态。独立的提供方／模型默认值会让同一部署产生两种答案，而在 Agent 与会话持久化完全停稳之前推导完成状态，会让 stdout 与退出状态观察到不完整状态。

 `headless-runner` 是直接使用核心服务的入口。Loader 完全加载后，它读取 `ctx.agentDefaultModel.currentSelection()`，通过 `ctx.agents.create` 创建一个新的持久化 Agent，在 Agent 作用域中安装该 `ModelSelection`，等待启动工作完全停稳，锚定会话事件序号，提交一条普通用户消息，再次等待完全停稳。随后，它等待 `ctx.sessions.flush`，折叠自身持有的持久事件区间，以取得最后一条非空 assistant 文本和最终 `turn/end` 结束原因，将文本连同一个换行写入 stdout，并且仅在结束原因为 `completed` 时请求启动器以退出状态 0 有界关闭。[Headless 推理进度](../feature/2026-08-21-headless-reasoning-progress.zh.md)负责实时 stderr 投影；结束原因为 `error` 时，其持久化错误码与消息写入 stderr，驱动器的意外失败也写入 stderr 并以 1 退出。

Four consumers (`ui-settings-general`, `ui-settings-models`, `ui-permission`, and `ui-commands`) reference API Remotes' Client face, which cannot compile until Host tsdown generates `@deepseek-ai/dsh-goal/remote`. That forms a build-order cycle: Host tsc needs API Remotes Client, which needs generated `goal/remote`, which Host tsdown emits after Host tsc.

+# Agent Note: Place unary browser operations on owning Remote services
+
+Status: implemented
+
+English | [中文](2026-08-10-unary-apiproxy-remote-migration.zh.md)
+
+## Problem
+
+The Host API Proxy duplicated simple unary operations across business Services, API Proxy interfaces, Zod schemas, route tables, client stubs, and Client callers. [Typert Remote calls](2026-08-02-typert-remote-method-calls.md) already let a business package own this class of call, but moving an endpoint without its lifecycle and projection policy could change observable behavior.
+
+Agent-bound calls require particular care. Shared lookup policy reuses live Agents, resumes ordinary cold Sessions with their recorded presets, deduplicates concurrent resumes, and rejects subagent-owned identities. Skill listing instead must inspect a Session without activating its Agent. Settings and preset operations keep their Host-owned document paths out of browser requests; Session file links preserve their caller-resolved path behavior.
+
+## Decision
+
+Simple unary operations live on their natural business Remote owner. The business package owns the Remote signature and Host adaptation; `@deepseek-ai/dsh-api-remotes/client` selects its generated contribution; the Client package owns presentation joins. Connection owns the transport envelope and exact Fetch route registry, and no API Proxy service remains.
+
+| Former API Proxy operation | Destination | Owner and preserved behavior |
+|---|---|---|
+| `session.rename` | `sessionTitle/rename` | `SessionTitleService` resolves the Session through the shared lookup policy and returns the title event sequence. |
+| `command.list`, `command.execute` | `commands/list`, `commands/execute` | `CommandRuntime` preserves Agent lookup, unmatched commands, and caller cancellation. |
+| `llm.providers` | `llm/listProviders`, `llm/listConfigurableProviders` | `LlmRuntime` owns provider facts; Clients join live and configurable rows. |
+| `llm.discoverModels` | `llm/discoverModels` | `LlmRuntime` preserves provider discovery, cancellation, and sanitized failures. |
+| `llm.models` | `session/modelCatalog` | `SessionController` owns the Host-generation catalog, default selection, and isolated provider failures. |
+| `credentials.describe`, `credentials.set`, `credentials.unset` | `credentials/describe`, `credentials/set`, `credentials/unset` | `CredentialsController` preserves reference validation, field projection, provider diagnostics, and refusal mapping. |
+| `settings.describe`, `settings.update`, `settings.replace`, `settings.mutate` | Equivalent `settings/*` methods | `SettingsController` preserves redaction, mutation semantics, revision checks, and provider failures. |
+| `settings.openDocument` | `settings/openSettingsDocument` | `SettingsController` prepares the provider-owned document and opens it with text-editor intent. |
+| `agentPreset.read`, `agentPreset.copy`, `agentPreset.remove` | Equivalent `agentPresets/*` methods | `AgentPresetService` owns document reads, copies, and removals. |
+| `agentPreset.openDocument` | `settings/openAgentPresetDirectory` | `SettingsController` resolves the preset directory and returns its path when native opening is unavailable. |
+| `subagent.interrupt` | `subagents/interruptByParent` | The subagent service preserves parent authority without activating either Agent. |
+| `workspace.list`, `workspace.insertSessionBefore`, `workspace.archiveSession` | Equivalent `workspace/*` methods | The Workspace registry owns detached snapshots and serialized mutations. |
+| `skill.list` | `skills/list` | `SessionSkillCatalog` observes the Session and its recorded preset, uses a live Agent only when one already exists, and never activates an Agent for listing. |
+| `fileReferences/list` | `fileReferences/list` | `SessionFileReferences` supplies the Session Controller's established Agent lookup to the provider; cold lookup behavior remains unchanged. |
+| `host.openPath` | `session/openWorkspacePath` | The Session-aware Client resolves relative paths against the known workspace before `SessionController` hands them to the native opener. |
+| `host.describe` | `$events` ready frame plus capability queries | API Remotes sends the Host home with generation readiness; Settings and Session controllers report their native-open capabilities when the corresponding page appears. Unused process metadata is not sent. |
+| `session.export` | `GET`/`HEAD /api/session.export` | `session-log-export` registers an exact Connection Fetch route and streams the ZIP without a JSON Remote envelope. |
+
+The shared Agent and Session resolver remains the authority for endpoints that accept those objects. It provides the same live reuse, cold restoration, concurrent deduplication, preset setup, persistence failures, and subagent ownership fence that legacy API Proxy calls used. `TypertLookupFailure` preserves resolver-owned RPC errors instead of collapsing them into `internal`.
+
+The native path implementation lives in `@deepseek-ai/dsh-native-command`. Settings controllers select Host-owned targets, while Session-aware Clients resolve workspace paths before calling `SessionController`; the utility only performs platform detection, WSL translation, browser preference, text-editor intent, and shell-free command execution.
+
+## Browser authentication
+
+Connection authenticates the complete `/api` request before choosing a Typert endpoint or exact Fetch route. Remote calls and Session-log downloads therefore require the same browser session and Host/Origin checks.
+
+## Verification
+
+Focused Host and Client tests cover Remote calls, lookup and no-activation policy, native opening, error projection, and removal of legacy routes. The repository build generates and consumes the selected Remote contributions before building the Web application.
+
+## Alternatives considered
+
+**Keep simple calls in the API Proxy.** Rejected because it preserves duplicate interfaces, schemas, route rows, stubs, and result projections after a business owner exists.
+
+**Keep `host.describe`.** Rejected because one bootstrap call coupled Connection readiness to unrelated process and business facts. The generation-ready frame carries the only lifecycle fact needed immediately, and capability-owning pages query their domains when shown.
+
+**Publish every business capability in the generation-ready frame.** Rejected because those values have no common update lifecycle. Only the stable Host home belongs to Connection; each business owner answers its own current capability.
+
+**Represent Session export as a Remote.** Rejected because the browser download manager consumes a streamed HTTP response rather than a JSON result. An exact registered Fetch route keeps ownership in the feature package without adding a second gateway.
+
+**Put native opening in one controller.** Rejected because Session and Settings select different authorized targets. A Host utility avoids controller-to-controller imports without making the browser authoritative for filesystem targets.
+
+## Consequences
+
+Business owners and Client consumers each define one side of a unary operation, while Connection owns authentication, transport, response envelopes, exact Fetch routes, and generation state. Removing the legacy client timeout is the accepted observable transport change; business results, cancellation, lifecycle policy, filtering, and native-path authority remain owned by their existing domains.
+
+Generated Remote artifacts and the explicit API Remotes assembly become required whenever a Remote signature or selected package changes.

+# Agent Note: 将一元浏览器操作放到所属 Remote 服务
+
+Status: implemented
+
+[English](2026-08-10-unary-apiproxy-remote-migration.md) | 中文
+
+## 问题
+
+Host API Proxy 曾在业务 Service、API Proxy interface、Zod schema、路由表、Client stub 与 Client 调用方之间重复定义简单一元操作。[Typert Remote 调用](2026-08-02-typert-remote-method-calls.zh.md)已经允许业务包持有这类调用，但如果迁移 endpoint 时没有一并保留生命周期与投影策略，就会改变可观察行为。
+
+与 Agent 绑定的调用需要格外谨慎。共享 lookup 策略会复用 live Agent、用记录的 preset 恢复普通冷 Session、对并发恢复去重，并拒绝由 subagent 持有的 identity。skill 列表则必须检查 Session 而不激活 Agent。Settings 与 preset 操作不会把 Host 持有的文档路径放进浏览器请求；Session 文件链接保留由调用方解析路径的行为。
+
+## 决策
+
+简单一元操作归属其自然的业务 Remote owner。业务包持有 Remote 签名与 Host 适配；`@deepseek-ai/dsh-api-remotes/client` 选择其生成贡献；Client 包持有呈现联接。Connection 持有传输 envelope 与精确 Fetch 路由注册表，不再存在 API Proxy 服务。
+
+| 原 API Proxy 操作 | 目标 | Owner 与保留行为 |
+|---|---|---|
+| `session.rename` | `sessionTitle/rename` | `SessionTitleService` 通过共享 lookup 策略解析 Session，并返回标题事件序号。 |
+| `command.list`、`command.execute` | `commands/list`、`commands/execute` | `CommandRuntime` 保留 Agent lookup、未匹配命令与调用方取消。 |
+| `llm.providers` | `llm/listProviders`、`llm/listConfigurableProviders` | `LlmRuntime` 持有 provider 事实；Client 联接 live 与 configurable 行。 |
+| `llm.discoverModels` | `llm/discoverModels` | `LlmRuntime` 保留 provider 发现、取消与净化后的失败。 |
+| `llm.models` | `session/modelCatalog` | `SessionController` 持有 Host generation 的目录、默认选择与隔离后的 provider 失败。 |
+| `credentials.describe`、`credentials.set`、`credentials.unset` | `credentials/describe`、`credentials/set`、`credentials/unset` | `CredentialsController` 保留引用校验、字段投影、provider 诊断与拒绝映射。 |
+| `settings.describe`、`settings.update`、`settings.replace`、`settings.mutate` | 对应的 `settings/*` 方法 | `SettingsController` 保留脱敏、mutation 语义、revision 校验与 provider 失败。 |
+| `settings.openDocument` | `settings/openSettingsDocument` | `SettingsController` 准备 provider 持有的文档，并按文本编辑器意图打开。 |
+| `agentPreset.read`、`agentPreset.copy`、`agentPreset.remove` | 对应的 `agentPresets/*` 方法 | `AgentPresetService` 持有文档读取、复制与删除。 |
+| `agentPreset.openDocument` | `settings/openAgentPresetDirectory` | `SettingsController` 解析 preset 目录，并在原生打开不可用时返回其路径。 |
+| `subagent.interrupt` | `subagents/interruptByParent` | subagent 服务保留 parent 权限，且不激活任何一方的 Agent。 |
+| `workspace.list`、`workspace.insertSessionBefore`、`workspace.archiveSession` | 对应的 `workspace/*` 方法 | Workspace registry 持有脱离可变对象的 snapshot 与串行 mutation。 |
+| `skill.list` | `skills/list` | `SessionSkillCatalog` 观察 Session 及其记录的 preset，仅在 live Agent 已存在时使用它，列表查询绝不激活 Agent。 |
+| `fileReferences/list` | `fileReferences/list` | `SessionFileReferences` 向 provider 提供 Session Controller 的既有 Agent lookup；冷 lookup 行为保持不变。 |
+| `host.openPath` | `session/openWorkspacePath` | Session-aware Client 先基于已知 workspace 解析相对路径，再由 `SessionController` 交给原生打开器。 |
+| `host.describe` | `$events` ready frame 与 capability 查询 | API Remotes 随 generation readiness 发送 Host home；Settings 与 Session controller 在对应页面显示时报告各自的原生打开能力。不发送无人使用的进程元数据。 |
+| `session.export` | `GET`/`HEAD /api/session.export` | `session-log-export` 注册精确的 Connection Fetch 路由，并在没有 JSON Remote envelope 的情况下流式传输 ZIP。 |
+
+共享 Agent 与 Session resolver 仍是接收这些对象的 endpoint 的权威。它提供与旧 API Proxy 调用相同的 live 复用、冷恢复、并发去重、preset setup、持久化失败与 subagent ownership fence。`TypertLookupFailure` 保留 resolver 持有的 RPC error，而不把它们归并为 `internal`。
+
+原生路径实现在 `@deepseek-ai/dsh-native-command` 中。Settings controller 选择 Host 持有的目标，Session-aware Client 则在调用 `SessionController` 前解析 workspace 路径；该工具仅负责平台探测、WSL 转换、浏览器偏好、文本编辑器意图与无 shell 命令执行。
+
+## 浏览器认证
+
+Connection 在选择 Typert endpoint 或精确 Fetch 路由前认证完整的 `/api` 请求。因此 Remote 调用与 Session 日志下载要求相同的浏览器会话和 Host/Origin 校验。
+
+## 验证
+
+聚焦的 Host 与 Client 测试覆盖 Remote 调用、lookup 与不激活策略、原生打开、错误投影和 legacy 路由移除。仓库构建会先生成并消费所选 Remote contribution，再构建 Web 应用。
+
+## 考虑过的替代方案
+
+**将简单调用留在 API Proxy。** 否决，因为业务 owner 已存在后，这仍会保留重复的 interface、schema、路由行、stub 与结果投影。
+
+**保留 `host.describe`。** 否决，因为一次 bootstrap 调用会把 Connection readiness 与互不相关的进程和业务事实耦合起来。generation-ready frame 只携带立即需要的生命周期事实，各 capability owner 页面在显示时查询自己的当前能力。
+
+**在 generation-ready frame 中发布所有业务 capability。** 否决，因为这些值没有共同的更新生命周期。只有稳定的 Host home 属于 Connection；各业务 owner 回答自己的当前 capability。
+

+# Agent Note: Session projections as a required reader seam
+
+Status: implemented
+
+English | [中文](2026-08-19-session-projection-mandatory-seam.zh.md)
+
+## Problem
+
+An optional projection registry lets a plugin whose host behavior reads projected state activate without that state. Unless the reader rejects the missing registry or key, the host behavior or subagent catalog fields can silently disappear. Batch-only reads also materialize every client view when a consumer needs one host value. Some contributor sites intentionally retain optional `ctx.inject` registration, so their readers need an explicit missing-state rule.
+
+## Decision
+
+This decision builds on the split between host projection state and client views in [Session projection state and client views](2026-08-19-session-projection-state-and-client-views.md).
+
+Every host reader treats the projection registry and its required key as mandatory state. A plugin either declares `sessionProjections` as a required injection or resolves the registry and key explicitly and throws on the first dependent access. Official compositions mount the registry before those plugins. `ApiProxyService` follows the required-injection form; the lower-level `createApiProxy` factory remains tolerant for isolated tests and diagnostics.
+
+A domain contributor may register its unit through `ctx.inject(['sessionProjections'], ...)`. Optional registration controls the child lifecycle only; it does not authorize a reader to substitute a default when the registry or key is absent.
+
+The registry provides `stateOf(session, key)` for one typed host state and keeps `snapshot()` for batch carriers. Client views contain only consumed fields; host readers use `stateOf` for richer state.
+
+`onChanged` publishes client-visible value changes only. Unit registration and removal remain effect-scoped registry lifecycle; `register()` returns the exact Cordis disposer so a composite domain owner can finish cleanup against projected state before removing its unit. Registration changes do not create a second Host event stream or client tombstone protocol. A later authoritative history or list baseline reflects the active key set.
+
+## Alternatives considered
+
+- **Default missing projected state.** This preserves more partial compositions but makes missing host state indistinguishable from a valid empty value. Rejected because official profiles mount the registry and configuration errors must fail explicitly.
+- **Require every contributor at activation.** This makes the key set uniform but unnecessarily couples contribution lifecycle to service activation. Explicit first-access failure preserves the optional registration form without allowing silent degradation.
+- **Use `snapshot()` for every read.** This keeps one method but computes unrelated wire views and encourages consumers to depend on batch transport data for host logic. Rejected in favor of typed single-key state reads.
+- **Send full host values to clients.** This avoids separate view types but exposes provenance and policy knobs that no client consumes. Rejected in favor of explicit cropped views.
+- **Broadcast registry additions and removals across Host and mux streams.** The streams have no shared ordering, so clients need tombstones, buffered frames, and baseline retries to reconcile them. Rejected because plugin-key churn does not justify a second synchronization protocol.
+
+## Consequences
+
+- Missing projection composition fails either during activation or at the first dependent host access; it never degrades to a default value.
+- Host consumers avoid repeated whole-registry snapshots and log scans.
+- Wire payloads exclude host-only fields and per-key watermark wrappers; ordinary baselines communicate the active key set.

+# Agent Note: 会话投影作为必需的读取 seam
+
+Status: implemented
+
+[English](2026-08-19-session-projection-mandatory-seam.md) | 中文
+
+## 问题
+
+可选的投影注册表会让 host 行为读取投影状态的插件在缺少该状态时仍然激活。除非读取方拒绝缺失的注册表或 key，否则 host 行为或 subagent 目录字段可能静默消失。只有批量读取也会在消费方只需要一个 host 值时物化每个客户端 view。部分贡献位置有意保留可选的 `ctx.inject` 注册形式，因此其读取方需要明确的缺失状态规则。
+
+## 决策
+
+本决策建立在[会话投影的 host 状态与客户端视图](2026-08-19-session-projection-state-and-client-views.zh.md)所定义的拆分之上。
+
+每个 host 读取方都把投影注册表及其所需 key 视为必需状态。插件要么把 `sessionProjections` 声明为必需注入，要么显式解析注册表与 key，并在第一次依赖它们的访问时抛错。正式组合在这些插件之前挂载注册表。`ApiProxyService` 采用必需注入形式；较低层的 `createApiProxy` factory 对隔离测试和诊断保持容错。
+
+领域贡献方可以通过 `ctx.inject(['sessionProjections'], ...)` 注册单元。可选注册只控制子功能生命周期；它并不允许读取方在注册表或 key 缺失时替换为默认值。
+
+注册表提供 `stateOf(session, key)` 来读取一个类型化 host 状态，并为批量 carrier 保留 `snapshot()`。客户端 view 只包含消费方使用的字段；host 读取方通过 `stateOf` 取得更丰富的状态。
+
+`onChanged` 只发布客户端可见值的变化。单元注册和移除仍是绑定 effect 的注册表生命周期；`register()` 返回 Cordis 的原始 disposer，使组合式领域 owner 可以先依据投影状态完成清理，再移除自身单元。注册变化不会创建第二条 Host 事件流或客户端 tombstone 协议。后续权威 history 或 list 基线会反映活跃 key 集。
+
+## 考虑过的替代方案
+
+- **为缺失的投影状态提供默认值。** 这会保留更多不完整组合，但缺失 host 状态将无法与合法空值区分。正式 profile 已挂载注册表，配置错误必须显式失败，因此否决。
+- **要求每个贡献方都在激活时强依赖。** 这会统一 key 集，却会让贡献生命周期与服务激活产生不必要的耦合。首次访问时显式失败既能保留可选注册形式，也不会允许静默降级。
+- **每次读取都使用 `snapshot()`。** 这只保留一个方法，但会计算无关 wire view，并鼓励消费方让 host 逻辑依赖批量传输数据。改用类型化单 key 状态读取。
+- **向客户端发送完整 host 值。** 这避免单独的 view 类型，但会暴露客户端不消费的来源信息和策略旋钮。改用显式裁剪的 view。
+- **跨 Host 和 mux stream 广播注册表新增和移除。** 两条 stream 没有共享顺序，客户端因此需要 tombstone、缓冲帧和基线重试来协调。插件 key 变化不值得引入第二套同步协议。
+
+## 后果
+
+- 缺少投影组合会在激活期间或第一次依赖它的 host 访问时失败，绝不会降级为默认值。
+- host 消费方避免重复的全注册表快照和日志扫描。
+- 协议负载排除 host 内部字段和逐 key 水位包装；普通基线会传达活跃 key 集。

-A unit whose key also appears in `SessionProjectionMap` supplies `wire.viewSchema` and `wire.view`. Every unit's state is checkpointed — client-visible and host-only alike; the `persist` opt-in is gone, so no unit can silently skip the durable cache. Snapshot APIs return only `SessionProjectionMap`, so internal states cannot enter API payloads. Host code reads one current state through `stateOf(session, key)`; the returned reference is borrowed and must not be mutated.
+A unit whose key also appears in `SessionProjectionMap` supplies `wire.viewSchema` and `wire.view`. Every unit's state is checkpointed — client-visible and host-only alike; the `persist` opt-in is gone, so no unit can silently skip the durable cache. Snapshot APIs enumerate only definitions with `wire`, so omitting an audience flag cannot place internal state in an API payload. Host code reads one current state through `stateOf(session, key)`; the returned reference is borrowed and must not be mutated.
 
 ## Consequences
 
-Projection state and client values are independently typed and validated without introducing a second client DTO vocabulary. A unit may expose a compact or compatibility-preserving client value while retaining richer host state. Malformed cached state cannot seed `viewCheckpoint`; restore rejects malformed state and the cache's existing full-read fallback rebuilds it from the log. Host consumers can replace private log scans with the same incremental fold used by carriers.

+
+Status: implemented
+
+English | [中文](2026-08-23-cross-realm-cdp-inspector.zh.md)
+
+## Problem
+
+Host diagnostics, browser Client observations, and JavaScript debugging originate in different JavaScript realms. A debugger transport implemented on the Host main thread cannot deliver `Debugger.resume` while that thread is paused, and a design that lets each producer emit CDP directly duplicates protocol state and couples application instrumentation to Chrome's presentation protocol.
+
+## Decision
+
+`@deepseek-ai/dsh-experimental-inspector` is one private Client/Host Cordis plugin package. Its Host face starts a Node Worker; its Client face connects directly to that Worker. Cordis owns composition, service publication, bootstrap injection, and disposal only. The source protocol, Worker state, CDP server, V8 bridge, and domain adapters do not inspect Cordis runtime data.
+
+The Worker is the sole CDP endpoint and the sole owner of CDP state. Host and Client producers send validated observations under a versioned internal protocol; Client Runtime, Console, Sources, and semantic queries use separate typed frame families on the same authenticated carrier. A realm registry gives every DevTools connection the same Runtime, Console, Sources, and Debugger capability slots, while explicit unsupported members preserve different Host and Client support levels.
+
+## Realm ownership
+
+The Host main thread owns application objects and `globalThis.fetch`. It sends observations over a dedicated `MessagePort` and never constructs CDP messages.
+
+The Client page owns browser observations, evaluated values, and Client object handles. It exchanges JSON frames directly with the Worker over an authenticated ingest WebSocket, so a paused Host does not stop Client delivery or Runtime execution.
+
+The Inspector Worker owns HTTP discovery, both WebSocket routes, source generations, retention, realm sessions, CDP sessions, and domain adapters. Each DevTools connection opens one backend session for the Host and every connected Client realm. V8 object ids remain inside the Node Runtime backend. Client object handles remain inside the typed Client protocol. One connection-local object table maps either backend handle to CDP object ids and projects the same RemoteObject, property, exception, Console, and paused-frame types.
+
+Chrome DevTools consumes one page-type target. Runtime methods route by execution context or object id. Debugger source methods route by script id; Host scripts retain native debugging, while Client scripts expose read-only content and reject active debugging. `Profiler` and `HeapProfiler` remain Host-only. `Network` and the minimal page-target scaffold run inside the Worker.
+
+## Source protocol
+
+Both MessagePort and WebSocket carriers use the same JSON value set and discriminated frames. A source identifies one logical producer and one connection generation, declares capabilities and topics, sends an initial replacement, then appends sequence-numbered batches. The Worker rejects malformed, oversized, stale-generation, and undeclared-topic frames before reading domain fields.
+
+Delivery is ordered and best-effort. Producers never wait for an acknowledgement on an application path. A bounded producer queue reports dropped prefixes through sequence gaps; the Host MessagePort carrier permits one append batch in flight and sends the next after the Worker acknowledges consumption. The Worker requests a new snapshot after an unexplained gap. Domain stores retain bounded state and explicitly close unfinished operations when a source disconnects.
+
+Runtime frames use closed command and result unions instead of method strings with untyped parameter records. Every request carries a source id, source generation, DevTools Runtime session id, request id, and command. Every result repeats those identities and the command discriminant. Console lifecycle/events, chunked source reads, and non-CDP semantic queries have separate correlated frame families. RemoteObject values, previews, property descriptors, call arguments, exceptions, Console events, debugger frames, scripts, and errors have dedicated exact decoders.
+
+## Client Runtime, Console, and Sources
+
+`Runtime.enable` publishes the Host's real execution context and one negative-id synthetic execution context for each connected Client source that declares the Runtime capability. An omitted context continues to mean Host. Client source replacement destroys the old context and creates a new context with a new generation and unique id.
+
+The Client Runtime subset covers `Runtime.evaluate`, `Runtime.getProperties`, `Runtime.callFunctionOn`, `Runtime.awaitPromise`, `Runtime.releaseObject`, `Runtime.releaseObjectGroup`, and `Runtime.globalLexicalScopeNames`. The Client executes commands in its page realm and retains live objects in a table isolated by DevTools Runtime session. It returns opaque handles and JSON-safe metadata; the Worker validates the result and assigns a connection-local CDP object id. An object argument may be used only by the same Client source generation and DevTools session. Closing the source, disabling Runtime, closing DevTools, releasing an object, or releasing an object group removes the corresponding handles.
+
+JavaScript exceptions are successful Runtime responses carrying `exceptionDetails`; transport failures use a separate error union. A Worker deadline sends request-scoped cancellation to the Client. Handles allocated for a response remain provisional until the Worker acknowledges that response, so cancellation and late responses cannot leave unreachable objects. Finite command deadlines, object counts, property counts, source bytes, and frame bytes bound retained or returned state.
+
+The Client Console observer preserves the original page call and asynchronously emits one event per enabled DevTools session. Each session serializes arguments into its own `console` object group, so disconnect, Runtime disable, or `Runtime.discardConsoleEntries` can release one connection without invalidating another. Context and Fiber arguments use the same semantic reference and DOM reverse mapping as evaluation results.
+
+The Client discovers this package's `lib/client.js` URL from the assembled web boot graph. `Debugger.enable` reads metadata through a typed source operation, and `Debugger.getScriptSource` reassembles bounded base64 chunks; the source map remains available at the advertised URL. Client-script breakpoint, step, and call-frame operations remain explicitly unsupported because page JavaScript cannot pause its own realm and continue servicing control messages. Target-wide pause and resume continue to control the Host debugger.
+
+## Host debugging
+
+The Worker attaches each DevTools connection to the Host main isolate through its own Node inspector Session. Node Runtime, Console, Sources, and Debugger backends normalize native values and events into the same realm model used by Client backends. The common projector allocates connection-local object ids for evaluation results, Console arguments, paused scopes, and call-frame results. Breakpoint requests are translated back to native backend handles before reaching Node. The default context may receive the display name `Host` while retaining its real id and metadata.
+
+The Worker event loop, DevTools socket, Client ingest socket, and Node inspector Session remain runnable while Host JavaScript is paused. Host observations naturally stop until resume.
+
+## Fetch capture
+
+Fetch capture wraps `globalThis.fetch` and is enabled by default. Every later fetch records its complete URL, headers, request body, response headers, response body, timing, cancellation, and error. No field is redacted by default; using the inspector grants local DevTools access to those secrets.
+
+The wrapper passes a normalized Request to the original fetch, reads request and response clones on independent capture tasks, and returns the original Response as soon as fetch resolves. Capture failure never changes the caller's fetch result. Finite per-body and journal budgets prevent unbounded retention; exceeding a budget preserves the captured prefix and reports truncation.
+
+## Alternatives considered
+
+**Run the CDP server on the Host main thread.** Rejected because a breakpoint freezes the socket responsible for delivering `Debugger.resume`.
+
+**Relay Client observations through the Host web server.** Rejected because the relay also freezes at a Host breakpoint and makes the Client data path depend on Host responsiveness.
+
+**Let producers emit CDP messages.** Rejected because producer code would own Chrome-specific request ids, replay, enable state, and ordering instead of domain observations.
+
+**Share one Node inspector Session across DevTools clients.** Rejected because object ids, object groups, enable state, and debugger operations belong to one protocol session; sharing requires an error-prone virtual-session layer.
+
+**Send live Client objects or CDP object ids over WebSocket.** Rejected because JSON cannot preserve identity or behavior, and a CDP object id belongs to one DevTools session. Client-local handles plus a Worker-owned per-connection mapping preserve both ownership rules.
+
+**Use one untyped Runtime RPC method.** Rejected because method strings and arbitrary parameter objects cannot enforce command/result correlation, object-reference ownership, or exhaustive evolution as Runtime, Sources, and Debugger support grows.
+
+**Split protocol, Host, and Client into separate packages.** Rejected for the experimental phase. One package keeps the capability deployable as one Client/Host plugin while source directories and build entries preserve realm boundaries.
+
+**Use Undici diagnostics channels as the complete fetch source.** Rejected because they observe transport lifecycle but cannot provide complete request and response bodies without consuming application streams. They may later augment transport-level timing.
+
+## Verification
+
+- A real Worker accepts Host MessagePort and Client WebSocket sources and exposes both through one CDP target.
+- Malformed, oversized, stale-generation, and sequence-gap frames cannot corrupt another source or the Worker.
+- Console evaluates in the Host context and receives Host console events.
+- Console lists Host and Client contexts; Client evaluation, properties, function calls, promise awaiting, and release operations preserve RemoteObject identity without sharing objects across realms or DevTools connections.
+- Host and Client Console events use the same projector; Client arguments remain isolated by DevTools connection and Cordis arguments resolve to Elements nodes.
+- Sources receives Host scripts and the built Client bundle; Client source reads are chunked and active debugging fails explicitly, while a breakpoint can pause the Host, evaluate a call frame, and resume.
+- Host paused scopes and call-frame results use the same connection-local RemoteObject table as Runtime evaluation.
+- Network replays requests that predate `Network.enable` and streams later requests without loss or duplication.
+- Successful, failed, aborted, redirected, textual, binary, streaming, and truncated fetches preserve caller behavior and expose the configured captured data.
+- Disposal stops capture, closes admission, disconnects V8 sessions, closes sockets, and waits for Worker exit before completing.
+
+## Consequences
+
+The Worker-owned endpoint keeps DevTools control responsive while Host JavaScript is paused and gives Host and Client observations one CDP state owner. That ownership adds the following security, resource, and compatibility costs.
+
+Full fetch capture intentionally exposes credentials and payloads to any local process that can attach to the CDP endpoint. Loopback binding is mandatory but is not authentication.
+
+Cloning request and response streams adds CPU, memory, and I/O pressure. Finite limits bound retained bytes but cannot make full capture free.
+
+A page-type synthetic target depends on a small set of Chrome DevTools compatibility responses outside Node's native inspector domains. Each no-op must be named and covered because silently accepting every unknown method hides protocol drift.
+
+Client Runtime execution uses page JavaScript evaluation, so page Content Security Policy may reject it and native DevTools command-line or REPL semantics are not promised. Read-only Client Sources do not imply active Client debugging; adding that capability requires an execution agent that remains responsive while the inspected page realm is paused.

+# Agent Note: 跨 realm CDP Inspector
+
+Status: implemented
+
+[English](2026-08-23-cross-realm-cdp-inspector.md) | 中文
+
+## Problem
+
+Host 诊断、浏览器 Client 观测和 JavaScript 调试来自不同 JavaScript realm。Host 主线程上的 debugger transport 无法在该线程暂停时投递 `Debugger.resume`；若每个 producer 直接生成 CDP，又会重复协议状态，并把应用观测逻辑绑到 Chrome 呈现协议。
+
+## Decision
+
+`@deepseek-ai/dsh-experimental-inspector` 是一个私有 Client/Host 双面 Cordis 插件包。Host 面启动 Node Worker，Client 面直接连接该 Worker。Cordis 只负责组合、服务发布、bootstrap 注入与 dispose；source 协议、Worker 状态、CDP server、V8 bridge 和 domain adapter 不检查 Cordis 运行时数据。
+
+Worker 是唯一 CDP endpoint，也是 CDP 状态的唯一 owner。Host 与 Client producer 通过有版本的内部协议发送验证后的观测记录；Client Runtime、Console、Sources 和语义查询在同一条鉴权 carrier 上使用相互独立的类型化帧。realm registry 为每条 DevTools 连接提供相同的 Runtime、Console、Sources 和 Debugger capability slot，并用明确的 unsupported 成员保留 Host 与 Client 的支持差异。
+
+## Realm 所有权
+
+Host 主线程拥有应用对象和 `globalThis.fetch`。它通过专用 `MessagePort` 发送观测记录，绝不构造 CDP 消息。
+
+Client 页面拥有浏览器观测、求值得到的值和 Client object handle。它通过带鉴权的 ingest WebSocket 直接与 Worker 交换 JSON 帧，因此 Host 暂停不会阻断 Client 投递或 Runtime 执行。
+
+Inspector Worker 拥有 HTTP discovery、两条 WebSocket route、source generation、保留历史、realm session、CDP session 和 domain adapter。每条 DevTools 连接为 Host 和每个已连接 Client realm 分别建立一套 backend session。V8 object id 只留在 Node Runtime backend 内。Client object handle 只留在类型化 Client 协议内。单个 connection-local object table 把两类 backend handle 映射成 CDP object id，并投影同一种 RemoteObject、property、exception、Console 与 paused-frame 类型。
+
+Chrome DevTools 消费一个 page 类型 target。Runtime 方法按 execution context 或 object id 路由；Debugger source 方法按 script id 路由。Host script 保留原生调试，Client script 只暴露只读内容，并拒绝 active debugging。`Profiler` 与 `HeapProfiler` 仍然只属于 Host；`Network` 与最小 page-target scaffold 在 Worker 内执行。
+
+## Source 协议
+
+MessagePort 与 WebSocket carrier 使用同一组 JSON 值和判别联合帧。source 标识一个逻辑 producer 和一个连接 generation，声明 capability 与 topic，发送初始 replace，再追加带 sequence 的 batch。Worker 在读取 domain 字段前拒绝畸形、超限、旧 generation 和未声明 topic 的帧。
+
+投递有序且尽力而为。producer 不在应用路径上等待 acknowledgement。有界 producer 队列通过 sequence gap 报告被丢弃的前缀；Host MessagePort carrier 同时只允许一个 append batch 在途，并在 Worker 确认消费后发送下一批。无法解释的 gap 会让 Worker 请求新 snapshot。domain store 只保留有界状态，并在 source 断开时明确关闭未完成操作。
+
+Runtime 帧使用封闭的 command 与 result 联合，而不是 method 字符串加无类型 parameter record。每个 request 携带 source id、source generation、DevTools Runtime session id、request id 和 command；每个 result 重复这些身份与 command 判别符。Console lifecycle/event、分块 source 读取和非 CDP 语义查询使用各自独立的关联帧。RemoteObject value、preview、property descriptor、call argument、exception、Console event、debugger frame、script 与 error 都有独立的精确 decoder。
+
+## Client Runtime、Console 与 Sources
+
+`Runtime.enable` 发布 Host 的真实 execution context，并为每个声明 Runtime 能力的已连接 Client source 发布一个负数 id synthetic execution context。不指定 context 仍然表示 Host。Client source replacement 会销毁旧 context，并以新的 generation 与 unique id 创建新 context。
+
+Client Runtime 子集包括 `Runtime.evaluate`、`Runtime.getProperties`、`Runtime.callFunctionOn`、`Runtime.awaitPromise`、`Runtime.releaseObject`、`Runtime.releaseObjectGroup` 和 `Runtime.globalLexicalScopeNames`。Client 在页面 realm 中执行命令，并在按 DevTools Runtime session 隔离的表中保留实时对象。Client 只返回不透明 handle 与 JSON-safe metadata；Worker 验证结果并分配连接私有的 CDP object id。对象参数只能由同一 Client source generation 与 DevTools session 使用。source 断开、Runtime disable、DevTools 关闭、释放对象或释放 object group 都会移除对应 handle。
+
+JavaScript exception 是携带 `exceptionDetails` 的成功 Runtime response；transport failure 使用独立的 error 联合。Worker deadline 会向 Client 发送 request-scoped cancellation。response 分配的 handle 在 Worker 确认该 response 前保持 provisional，因此 cancellation 和 late response 不会留下无法访问的对象。有限的命令 deadline、对象数、属性数、source 字节数与帧字节数约束保留或返回的状态。
+
+Client Console observer 保持原始页面调用行为，并为每个已启用的 DevTools session 异步发出一份 event。每个 session 把 argument 序列化到自己的 `console` object group，因此断联、Runtime disable 或 `Runtime.discardConsoleEntries` 可以释放一条连接而不使其他连接失效。Context 与 Fiber argument 使用和求值结果相同的语义引用及 DOM 反向映射。
+
+Client 从组装后的 web boot graph 发现本包 `lib/client.js` 的 URL。`Debugger.enable` 通过类型化 source operation 读取 metadata，`Debugger.getScriptSource` 重组有界 base64 chunk；source map 保持在公布的 URL 上可用。Client script breakpoint、step 与 call-frame 操作明确不受支持，因为页面 JavaScript 无法暂停自身 realm 后继续处理控制消息。target-wide pause 与 resume 继续控制 Host debugger。
+
+## Host 调试
+
+Worker 为每条 DevTools 连接建立独立 Node inspector Session，并连接 Host 主 isolate。Node Runtime、Console、Sources 与 Debugger backend 把原生 value 和 event 归一化成 Client backend 使用的同一种 realm model。公共 projector 为求值结果、Console argument、paused scope 和 call-frame result 分配 connection-local object id。breakpoint request 到达 Node 前会反向转换成原生 backend handle。默认 context 可以改显示名为 `Host`，但保留真实 id 和 metadata。
+
+Host JavaScript 暂停时，Worker event loop、DevTools socket、Client ingest socket 与 Node inspector Session 仍可运行。Host 观测自然暂停到 resume。
+
+## Fetch 采集
+
+fetch 采集包装 `globalThis.fetch`，并默认开启。之后每次 fetch 都记录完整 URL、headers、请求体、响应 headers、响应体、时间、取消与错误。默认不脱敏任何字段；启用 Inspector 即把这些秘密交给本机 DevTools。
+
+wrapper 把标准化 Request 交给原 fetch，通过独立采集任务读取 request/response clone，并在 fetch resolve 后立即把原始 Response 交给调用方。采集失败不得改变调用方的 fetch 结果。有限的单体与 journal 预算阻止无界保留；超过预算时保留已采集前缀并报告截断。
+
+## Alternatives considered
+
+**在 Host 主线程运行 CDP server。** 拒绝，因为断点会冻结负责投递 `Debugger.resume` 的 socket。
+
+**经 Host web server 中转 Client 观测。** 拒绝，因为 Host 断点同样冻结中转，并使 Client 数据路径依赖 Host 响应。
+
+**让 producer 直接生成 CDP 消息。** 拒绝，因为 Chrome 专用 request id、回放、enable 状态和排序会落入 producer，而不是领域观测。
+
+**多个 DevTools client 共用一个 Node inspector Session。** 拒绝，因为 object id、object group、enable 状态与 debugger 操作属于单个协议 session；共享需要易错的虚拟 session 层。
+
+**通过 WebSocket 发送 Client 实时对象或 CDP object id。** 拒绝，因为 JSON 无法保留对象身份或行为，而 CDP object id 只属于一条 DevTools session。Client-local handle 加 Worker 所有的逐连接映射同时维护这两条所有权规则。
+
+**使用一个无类型 Runtime RPC method。** 拒绝，因为 method 字符串和任意 parameter object 无法保证 command/result 关联、对象引用所有权，也无法在 Runtime、Sources 与 Debugger 支持增长时做穷尽演进。
+
+**把 protocol、Host 与 Client 拆成多个包。** 实验阶段拒绝。一个包保持能力以一个 Client/Host 插件部署，同时由源码目录与构建入口维护 realm 边界。
+
+**用 Undici diagnostics channel 作为完整 fetch 数据源。** 拒绝，因为它能观察 transport lifecycle，却无法在不消费应用 stream 的前提下提供完整 request/response body。后续可以用它补充 transport 级 timing。
+
+## Verification
+
+- 真实 Worker 同时接收 Host MessagePort 与 Client WebSocket source，并通过一个 CDP target 暴露两者。
+- 畸形、超限、旧 generation 与 sequence gap 帧不会破坏其他 source 或 Worker。
+- Console 在 Host context 求值并接收 Host console event。
+- Console 列出 Host 与 Client context；Client 求值、属性、函数调用、Promise await 与释放操作维持 RemoteObject 身份，且不在 realm 或 DevTools 连接之间共享对象。
+- Host 与 Client Console event 使用相同 projector；Client argument 按 DevTools 连接隔离，Cordis argument 可以解析到 Elements node。
+- Sources 接收 Host script 与构建后的 Client bundle；Client source 读取采用分块传输，active debugging 明确失败，而 Host 仍可被断点暂停、求值 call frame 并 resume。
+- Host paused scope 与 call-frame result 使用和 Runtime 求值相同的 connection-local RemoteObject table。
+- Network 回放 `Network.enable` 前的请求，并无遗漏、无重复地推送后续请求。
+- 成功、失败、取消、重定向、文本、二进制、流式与截断 fetch 都保持调用方行为，并暴露配置允许的完整采集数据。
+- dispose 停止采集、关闭入口、断开 V8 session、关闭 socket，并等待 Worker exit 后完成。
+
+## Consequences
+
+Worker 所有的 endpoint 在 Host JavaScript 暂停时仍保持 DevTools 控制可响应，并让 Host 与 Client 观测共享唯一 CDP 状态 owner。这项所有权带来以下安全、资源与兼容性成本。
+
+完整 fetch 采集会有意把 credential 和 payload 暴露给任何能连接 CDP endpoint 的本机进程。loopback 监听是强制要求，但不是鉴权。
+
+clone request/response stream 会增加 CPU、内存与 I/O 压力。有限预算能约束保留字节，不能让完整采集没有成本。
+
+page 类型 synthetic target 依赖 Node 原生 inspector domain 之外的一组 Chrome DevTools 兼容响应。每个 no-op 都必须明确命名并有测试；统一吞掉未知方法会掩盖协议漂移。
+
+Client Runtime 执行使用页面 JavaScript 求值，因此页面 Content Security Policy 可能拒绝它，也不承诺原生 DevTools command-line 或 REPL 语义。只读 Client Sources 不代表 active Client debugging；增加该能力需要一个在被检查页面 realm 暂停时仍能响应的执行 agent。

+# Agent Note: Cordis runtime tree inspection
+
+Status: implemented
+
+English | [中文](2026-08-24-cordis-runtime-tree-inspection.zh.md)
+
+## Problem
+
+The Inspector needs to present each Host and Client Cordis runtime as a tree in Chrome DevTools Elements. A Cordis Context or Fiber selected in Elements must also behave as a live Runtime object, while a Cordis object printed in Console must be revealable as the same semantic node. CDP identifiers cannot be the source model: `NodeId`, `BackendNodeId`, and `RemoteObjectId` have different owners and lifetimes, and a future model-facing runtime query must consume the same Cordis data without translating CDP.
+
+Host and Client run the same Cordis abstractions in different JavaScript realms. Tree discovery and classification must therefore be one browser-safe implementation, while object resolution remains realm-local and only opaque references cross MessagePort or WebSocket boundaries.
+
+## Decision
+
+The Inspector uses one serialized Cordis tree model and keeps CDP as one adapter over it. The package separates live-object discovery, immutable snapshots, Worker-owned storage, and consumers:
+
+The existing [cross-realm Inspector decision](../../implemented/architecture/2026-08-23-cross-realm-cdp-inspector.md) owns the Worker, source carriers, Runtime routing, and security model. This note owns only the Cordis semantic data and its consumers.
+
+```text
+Host Context/Fiber ─┐
+                    ├─ CordisTreeCollector ─ CordisTreeSnapshot ─ source transport ─ CordisTreeStore ─┬─ CDP DOM adapter
+Client Context/Fiber┘                                                                                 └─ future model adapter
+```
+
+`CordisTreeCollector` and its identity registry are browser-safe modules compiled into both package faces. Host and Client instantiate that same code against their own `ctx.root`; neither side carries a second classification implementation.
+
+## Cordis tree model
+
+`CordisTreeSnapshot` is a CDP-independent, lossless-JSON value with a schema version, monotonically increasing revision, object-registry id, truncation flag, and one nested root Context. Context nodes contain an opaque object handle and ordered Context/Fiber children. Fiber nodes contain their Cordis `uid`, an opaque object handle, and exactly one Context child representing `fiber.ctx`. Host and Client publish this same realm-tree type. No generated Context id, plugin metadata, service data, arbitrary property value, or object preview enters the tree.
+
+The inspection tree starts at the root Context and omits the Cordis root Fiber. For every other plugin, its parent Context contains the Fiber and that Fiber contains its owned Context. A Context created by `extend()`, `isolate()`, or `intercept()` without a new Fiber remains a direct Context child. Nesting expresses parentage without generated node ids and preserves both object identities without introducing the `Fiber.ctx` / `Context.fiber` cycle.
+
+The collector starts from the root, every live registry Fiber, and every event hook's owning Context. It follows Context prototype links back to the inspected root, unwraps Cordis shadow contexts, deduplicates by object identity, and excludes disposed fibers. `internal/plugin` and `internal/status` events schedule one microtask-coalesced replacement snapshot. Node-count and encoded-byte limits remove complete trailing branches, so every retained node still has its parent and every retained Fiber still has its owned Context.
+
+## Identity and lifetime
+
+The identities are intentionally distinct:
+
+- Fiber `uid` comes from Cordis. Context currently has no Cordis-owned id and the Inspector does not expose a generated substitute.
+- `InspectorObjectReference` is an opaque realm-local handle resolving a tree node to its live Context or Fiber. Snapshots carry the handle for routing, never as a semantic id or DOM attribute.
+- `BackendNodeId` is assigned by the Worker to one retained `(source id, source generation, object reference)` and is shared by DevTools connections while that generation's snapshot is retained.
+- `NodeId` is assigned per DevTools connection when a node enters that frontend's document. It remains stable while the corresponding backend node is retained and is discarded when that node leaves the tree, on the rare full-document fallback, or when the connection closes.
+- `RemoteObjectId` is assigned by the selected Runtime session when `DOM.resolveNode` exposes the live object. It remains scoped to that DevTools connection and object group.
+
+`sourceId` identifies one browser-tab Client runtime and is retained in that tab's `sessionStorage`, so automatic transport reconnects and page refreshes reuse it. Before opening the transport, a Client with Web Locks claims that id for its page lifetime; a simultaneously live tab copied from the same storage state cannot claim it and persists a fresh id instead. Browsers without Web Locks retain storage-backed refresh identity but cannot arbitrate copied live tabs. `generation` identifies one WebSocket admission and always rotates. Disconnect removes the synthetic context from the Console with `Runtime.executionContextDestroyed`. Reconnection announces a fresh CDP execution-context id because the destroyed id and its RemoteObjects cannot be reused, but this does not imply that the browser's underlying JavaScript realm was recreated.
+
+Standard CDP does not place a `RemoteObjectId` field on `DOM.Node`. `DOM.Node` carries `nodeId` and `backendNodeId`; `DOM.resolveNode` returns the corresponding `Runtime.RemoteObject`, and `DOM.requestNode` performs the reverse mapping. The implementation keeps these three CDP identities correlated without adding non-standard DOM fields.
+
+## Realm object bridge
+
+Each collector registers a realm-local object table under a private global symbol. The table maps opaque handles to live objects and can identify a currently retained object by identity. Replacing a snapshot removes handles absent from the new tree; disposing the observer unregisters the table.
+
+For Host nodes, the Worker uses that DevTools connection's private `node:inspector.Session` to evaluate a lookup in the Host table, producing a native V8 `RemoteObjectId`. For Client nodes, the Worker routes the same lookup through the existing typed Client Runtime channel and maps the returned Client handle to a connection-local CDP object id. No live object or engine object id crosses a source transport.
+
+Client Runtime values carry an optional validated `InspectorObjectReference`, while Host Runtime values are probed through their native V8 object id. The common CDP adapter changes recognized evaluation results, properties, exceptions, Console arguments, and paused-frame objects to `subtype: "node"`, records the object-id-to-backend-node relation, and supplies the Cordis element description. This gives both directions: Elements can expose a live object, and a Context or Fiber returned or printed in Console can be revealed in Elements.
+
+## Worker repository and updates
+
+Sources publish the Cordis tree as retained state rather than an event history. Host MessagePort and Client WebSocket publishers keep the latest state record and include it in `source/replace` after admission, reconnection, or a resnapshot request. Live replacements still use the ordinary sequenced append path. The Worker validates every snapshot for exact fields, bounded node count and depth, unique object handles and Fiber uids, a Context root, and exactly one Context child per Fiber before atomically replacing the prior tree.
+
+`CordisTreeStore` owns validated realm snapshots and source lifecycle only. Its internal reader retains live object routes for Runtime and DOM, while its public reader projects a detached `{ host, clients }` tree without transport or CDP ids. Host and Client `ctx.inspector.cordis.getTree()` calls use the same correlated query protocol and Worker reader without creating a CDP session. `CordisDomBackend` adds Worker-global backend ids, while each `CordisDomSession` owns frontend node ids, searches, enabled state, and RemoteObject correlations. A model adapter can consume the public reader without depending on DOM serialization or debugger activation.
+
+Closing a source changes its stored tree from connected to disconnected instead of deleting the last snapshot. Object lookup excludes disconnected trees, so the snapshot remains inspectable as data without retaining or reviving a live Context, Fiber, or Runtime object. A replacement from the same source id and a new transport generation atomically restores the connected state. The configurable disconnected-tree limit evicts the oldest retained snapshots.
+
+Accepted source snapshots rebuild the connection-neutral document and are diffed by stable backend node identity. A revision-only replacement emits no DOM event. Child insertion and removal use `DOM.childNodeInserted` and `DOM.childNodeRemoved`; attribute changes use their corresponding DOM events; sibling reorder falls back to `DOM.setChildNodes` for that parent only. Reusing one backend identity for a different node kind is the sole `DOM.documentUpdated` fallback. A disconnect invalidates object routes without changing the retained DOM tree, preserving expansion and selection; retention eviction removes only the evicted `<client>` node.
+
+## CDP projection
+
+The synthetic document has a `<host>` container and a `<clients>` container. `<host>` contains the Host root Context. `<clients>` contains one `<client>` per Client source, and each `<client>` contains that realm's root Context. These structural elements have no Runtime object or attributes. Context elements have no attributes. Fiber elements expose only `uid`, copied without reinterpretation from Cordis. Connected Context and Fiber elements resolve to live RemoteObjects; disconnected snapshots retain their DOM nodes but object resolution fails.
+
+Standard CDP has no backend-controlled frozen, locked, or dimmed state for a node in the ordinary Elements tree. Chromium's detached-node presentation is frontend-local to the Memory panel's `DOM.getDetachedDomNodes` flow. No connection-state attribute or non-standard `DOM.Node` field is added until its presentation is decided.
+
+The read-only adapter implements document retrieval, child requests, node description, attributes, outer HTML, search, backend-id pushes, node resolution, and reverse object lookup. Mutating DOM methods fail explicitly. Layout, CSS, accessibility, and browser DOM geometry are outside this semantic tree and return empty or unsupported responses only where Chrome DevTools requires a compatibility response.
+
+## Alternatives considered
+
+**Build CDP DOM nodes directly in each realm.** Rejected because Host and Client would duplicate classification, frontend ids would leak into source protocols, and a model consumer would need to reverse a presentation protocol back into Cordis concepts.
+
+**Send live objects or V8 object ids to the Worker.** Rejected because structured clone and JSON do not preserve identity or behavior, and engine object ids belong to one inspector session.
+
+**Generate an Inspector Context id.** Rejected because Cordis Context has no intrinsic id and a presentation adapter must not make an implementation key look like framework identity. Nested children express parentage; opaque object handles remain routing data.
+
+**Use one id for Fiber uid, backend nodes, and frontend nodes.** Rejected because source reconnection, multiple DevTools connections, document refresh, and Runtime object release have independent lifetimes.
+
+**Expose only Contexts and treat each Fiber-owned Context as the Fiber.** Rejected because it loses one of the two live objects, makes Console identity ambiguous, and prevents later Fiber-specific properties from having a stable owner.
+
+**Put the model-facing API on the CDP adapter.** Rejected because model access would inherit Chrome-specific node serialization, per-connection ids, and enable state. The Worker repository is the shared source; CDP and model access are sibling adapters.
+
+**Remove a realm tree when its source disconnects.** Rejected because transport loss would discard the last useful topology and collapse the user's Elements inspection state. Keeping old object handles usable was also rejected: a new connection generation cannot prove that any prior live object still exists.
+
+## Verification
+
+- The same collector implementation produces Host and Client snapshots from equivalent Cordis runtimes.
+- Elements shows `<host>` and `<clients>/<client>` containers with each realm's root Context directly beneath its container.
+- Context elements have no attributes; Fiber elements expose only their Cordis `uid`; the root Fiber is absent.
+- Every connected Context and Fiber has a connection-local frontend node id, a Worker backend node id, and a resolvable connection-local Runtime object id without exposing them as attributes.
+- `DOM.resolveNode` and `DOM.requestNode` round-trip Context and Fiber identities without sharing object ids across DevTools connections or source generations.
+- A Context or Fiber returned by Runtime evaluation is node-branded and can be revealed in Elements.
+- Disconnect destroys the Client execution context and its RemoteObjects while retaining the last Elements tree unchanged; a new transport generation replaces it after a complete snapshot arrives.
+- Reconnect and resnapshot replay the latest tree state; unchanged snapshots emit no DOM mutation, while structural changes update only their affected parent or node. Malformed or oversized replacements do not replace the last valid snapshot.
+- The stored snapshot and query API contain no CDP types and can support a future model-facing adapter unchanged.
+
+## Consequences
+
+Cordis exposes no complete global Context registry. The collector can recover contexts reachable from live fibers and event hooks; a context that is created, never used, and retained only by application code is intentionally absent.
+
+Object recognition adds a Runtime round trip for each Host object that requires semantic identification. An annotation failure leaves an ordinary RemoteObject rather than breaking Runtime or Debugger delivery. Client Console observation preserves the original method result and schedules serialization afterward; each enabled DevTools session receives independently retained handles, so recognition never blocks the page call or shares objects between connections.
+
+Sources continue to publish complete snapshots, keeping one shared Host/Client collector and allowing recovery after dropped observations. The Worker pays the snapshot comparison cost, then emits incremental CDP DOM mutations so unchanged revisions do not reset the Elements document. Node and byte limits preserve a valid prefix and report truncation; a later source delta protocol can replace the transport without changing the snapshot model or CDP projection.
+
+The object table intentionally keeps every object in the current visible tree strongly reachable until the next replacement or observer disposal. This is bounded by the retained snapshot and must not become a general-purpose object registry.
+
+The Worker retains only serialized metadata for a disconnected snapshot; any still-running source owns its realm-local object registry independently and disposal releases that registry. `maxDisconnectedCordisTrees` bounds Worker snapshot memory, and eviction removes the corresponding retained Client subtree.

+# Agent Note: Cordis 运行时树检查
+
+Status: implemented
+
+[English](2026-08-24-cordis-runtime-tree-inspection.md) | 中文
+
+## Problem
+
+Inspector 需要在 Chrome DevTools Elements 中把每个 Host 和 Client Cordis 运行时呈现为一棵树。在 Elements 中选中的 Cordis Context 或 Fiber 也必须表现为实时 Runtime 对象，而 Console 中打印出的 Cordis 对象必须能定位回同一个语义节点。CDP id 不能成为源模型：`NodeId`、`BackendNodeId` 与 `RemoteObjectId` 的 owner 和生命周期不同，并且未来面向模型的运行时查询必须使用同一份 Cordis 数据，而不是再反向解析 CDP。
+
+Host 与 Client 在不同 JavaScript realm 中运行相同的 Cordis 抽象。因此，树发现与分类必须只有一份浏览器安全实现；对象解析仍留在各自 realm 内，跨 MessagePort 或 WebSocket 只传递不透明引用。
+
+## Decision
+
+Inspector 使用一套序列化 Cordis 树模型，并把 CDP 作为它的一个适配器。包内分离实时对象发现、不可变快照、Worker 存储与消费方：
+
+现有的[跨 realm Inspector 决策](../../implemented/architecture/2026-08-23-cross-realm-cdp-inspector.zh.md)负责 Worker、source carrier、Runtime 路由与安全模型；本 Note 只负责 Cordis 语义数据及其消费方。
+
+```text
+Host Context/Fiber ─┐
+                    ├─ CordisTreeCollector ─ CordisTreeSnapshot ─ source transport ─ CordisTreeStore ─┬─ CDP DOM adapter
+Client Context/Fiber┘                                                                                 └─ future model adapter
+```
+
+`CordisTreeCollector` 及其身份注册表是浏览器安全模块，同时编入包的两个运行面。Host 与 Client 针对各自的 `ctx.root` 实例化同一份代码；任何一侧都不维护第二套分类实现。
+
+## Cordis tree model
+
+`CordisTreeSnapshot` 是与 CDP 无关的无损 JSON 值，包含 schema 版本、单调递增 revision、对象注册表 id、截断标志和一棵以 Context 为根的嵌套树。Context 节点包含不透明 object handle 与有序的 Context/Fiber children。Fiber 节点包含 Cordis `uid`、不透明 object handle，以及唯一一个表示 `fiber.ctx` 的 Context child。Host 与 Client 发布同一种 realm-tree 类型。生成的 Context id、插件 metadata、服务数据、任意属性值与对象 preview 都不进入树。
+
+inspection tree 从 root Context 开始，不包含 Cordis root Fiber。对其他每个插件，其 parent Context 包含 Fiber，该 Fiber 再包含它拥有的 Context。通过 `extend()`、`isolate()` 或 `intercept()` 创建且未创建新 Fiber 的 Context 仍是直接 Context 子节点。嵌套结构无需生成 node id 即可表达 parent，并保留两类对象身份，同时避免把 `Fiber.ctx` / `Context.fiber` 环写入序列化树。
+
+collector 从 root、注册表中的每个 live Fiber，以及每个 event hook 的 owner Context 开始。它沿 Context prototype 链回溯到被检查的 root，解开 Cordis shadow Context，按对象身份去重，并排除已 dispose 的 Fiber。`internal/plugin` 与 `internal/status` 事件调度一次 microtask 合并后的 replacement snapshot。节点数和编码字节数限制会移除完整的尾部 branch，因此每个保留节点仍有 parent，每个保留 Fiber 仍有其 owned Context。
+
+## Identity and lifetime
+
+各类身份刻意保持独立：
+
+- Fiber `uid` 来自 Cordis。Context 当前没有 Cordis 自有 id，Inspector 不会暴露一个生成值来替代。
+- `InspectorObjectReference` 是 realm 本地的不透明 handle，用于把树节点解析成实时 Context 或 Fiber。snapshot 携带该 handle 只为完成路由，不把它当成语义 id 或 DOM attribute。
+- `BackendNodeId` 由 Worker 为一条保留的 `(source id, source generation, object reference)` 分配，并在该 generation 的 snapshot 被保留期间由所有 DevTools 连接共享。
+- `NodeId` 在节点进入某个 frontend document 时按 DevTools 连接分配；对应 backend node 被保留期间保持稳定，并在节点离开树、少见的整 document fallback 或连接关闭时丢弃。
+- `RemoteObjectId` 在 `DOM.resolveNode` 暴露实时对象时由选定的 Runtime session 分配；它只属于该 DevTools 连接和 object group。
+
+`sourceId` 标识一个浏览器 tab 的 Client runtime，并保存在该 tab 的 `sessionStorage` 中，因此自动重连 transport 与页面刷新都会复用它。Client 在打开 transport 前会在 Web Locks 可用时独占该 id，直至页面结束；从同一存储状态复制出的另一个同时存活 tab 无法取得该锁，因而会持久化一个新 id。缺少 Web Locks 的浏览器仍保留基于存储的刷新身份，但无法仲裁复制出的 live tab。`generation` 标识一次 WebSocket 接纳且每次都会轮换。断联通过 `Runtime.executionContextDestroyed` 从 Console 移除 synthetic context。重连会发布新的 CDP execution-context id，因为已销毁的 id 及其 RemoteObject 不能复用；这并不表示浏览器底层 JavaScript realm 被重新创建。
+
+标准 CDP 不会在 `DOM.Node` 上放置 `RemoteObjectId` 字段。`DOM.Node` 携带 `nodeId` 与 `backendNodeId`；`DOM.resolveNode` 返回对应的 `Runtime.RemoteObject`，`DOM.requestNode` 执行反向映射。实现会关联这三类 CDP 身份，而不添加非标准 DOM 字段。
+
+## Realm object bridge
+
+每个 collector 都在私有 global symbol 下注册一个 realm 本地对象表。该表把不透明 handle 映射到实时对象，并能按身份识别当前保留的对象。替换快照时会移除新树中不存在的 handle；dispose observer 时注销该表。
+
+对 Host 节点，Worker 使用该 DevTools 连接私有的 `node:inspector.Session` 在 Host 对象表中执行查询，从而生成原生 V8 `RemoteObjectId`。对 Client 节点，Worker 通过已有的类型化 Client Runtime channel 路由同一查询，再把返回的 Client handle 映射为连接本地 CDP object id。实时对象和引擎 object id 都不会穿过 source transport。
+
+Client Runtime value 携带一个可选、已验证的 `InspectorObjectReference`，Host Runtime value 则通过原生 V8 object id 探测。公共 CDP adapter 把已识别的 evaluation result、property、exception、Console argument 和 paused-frame object 改成 `subtype: "node"`，记录 object-id 到 backend-node 的关系，并提供 Cordis element description。这样两个方向都成立：Elements 可以暴露实时对象，Console 中返回或打印的 Context 与 Fiber 也能定位到 Elements。
+
+## Worker repository and updates
+
+source 把 Cordis 树作为保留状态发布，而不是事件历史。Host MessagePort 与 Client WebSocket publisher 保留最新状态记录，并在接纳、重连或收到 resnapshot 请求后把它放入 `source/replace`。实时 replacement 仍走普通的有序 append 路径。Worker 在原子替换旧树前验证 snapshot 的精确字段、节点数与深度限制、object handle 与 Fiber uid 唯一性、Context root，以及每个 Fiber 恰好拥有一个 Context child。
+
+`CordisTreeStore` 只拥有已验证 realm snapshot 和 source 生命周期。内部 reader 为 Runtime 与 DOM 保留 live object route；公共 reader 则投影一棵不含 transport 或 CDP id 的 detached `{ host, clients }` tree。Host 与 Client 的 `ctx.inspector.cordis.getTree()` 通过同一套关联查询协议读取同一个 Worker reader，不创建 CDP session。`CordisDomBackend` 增加 Worker 全局 backend id，每个 `CordisDomSession` 则拥有 frontend node id、搜索、enable 状态和 RemoteObject 关联。模型 adapter 可以消费公共 reader，而不依赖 DOM 序列化或 debugger activation。
+
+source 关闭时，存储的树从 connected 变为 disconnected，而不是删除最后一份 snapshot。对象查询会排除 disconnected 树，因此 snapshot 仍可作为数据检查，但不会保留或复活实时 Context、Fiber 或 Runtime object。同一 source id 的新 transport generation 提交 replacement 后，会原子恢复 connected 状态。可配置的 disconnected tree 数量上限会淘汰最早保留的 snapshot。
+
+每个被接受的 source snapshot 都会重建 connection-neutral document，并按稳定的 backend node identity 比较差异。只改变 revision 的 replacement 不发送 DOM event；子节点增删使用 `DOM.childNodeInserted` 与 `DOM.childNodeRemoved`，attribute 变化使用对应 DOM event，兄弟节点重排只对该 parent 使用 `DOM.setChildNodes`。只有同一 backend identity 被复用为不同 node kind 时才回退到 `DOM.documentUpdated`。断联只会使 object route 失效，不改变保留的 DOM tree，因此保留展开与选择；达到保留上限时只移除被淘汰的 `<client>` 节点。
+
+## CDP projection
+
+synthetic document 包含一个 `<host>` container 和一个 `<clients>` container。`<host>` 包含 Host root Context；`<clients>` 为每个 Client source 包含一个 `<client>`，每个 `<client>` 再包含该 realm 的 root Context。这些结构 element 没有 Runtime object 或 attribute。Context element 没有 attribute。Fiber element 只暴露从 Cordis 原样复制的 `uid`。connected Context 与 Fiber 可以解析为 live RemoteObject；disconnected snapshot 保留 DOM node，但对象解析失败。
+
+标准 CDP 没有可由 backend 控制、用于普通 Elements 树节点的 frozen、locked 或 dimmed 状态。Chromium 的 detached-node 展示只存在于 Memory 面板的 `DOM.getDetachedDomNodes` 流程，并由 frontend 本地设置。在展示方式明确前，不增加 connection-state attribute 或非标准 `DOM.Node` 字段。
+
+只读适配器实现 document 获取、子节点请求、节点描述、属性、outer HTML、搜索、backend-id push、节点解析和对象反向查询。修改型 DOM 方法明确失败。layout、CSS、accessibility 与浏览器 DOM geometry 不属于这棵语义树；仅在 Chrome DevTools 需要兼容响应时返回空结果或 unsupported。
+
+## Alternatives considered
+
+**在每个 realm 直接构建 CDP DOM node。** 拒绝，因为 Host 与 Client 会重复分类，frontend id 会泄漏进 source 协议，模型消费方还必须把展示协议反向解析成 Cordis 概念。
+
+**把实时对象或 V8 object id 发送给 Worker。** 拒绝，因为 structured clone 与 JSON 无法保留身份或行为，而且引擎 object id 只属于一个 inspector session。
+
+**由 Inspector 生成 Context id。** 拒绝，因为 Cordis Context 没有自身 id，展示适配器不能把实现 key 伪装成框架身份。嵌套 children 表达 parent，不透明 object handle 只作为路由数据。
+
+**Fiber uid、backend node 与 frontend node 共用一个 id。** 拒绝，因为 source 重连、多条 DevTools 连接、document refresh 与 Runtime object release 的生命周期彼此独立。
+
+**只暴露 Context，并把每个 Fiber 拥有的 Context 当成 Fiber。** 拒绝，因为这会丢失两类实时对象中的一类，使 Console 身份产生歧义，并让后续 Fiber 专属属性失去稳定 owner。
+
+**把模型访问 API 放在 CDP 适配器上。** 拒绝，因为模型访问会继承 Chrome 专用 node 序列化、逐连接 id 和 enable 状态。Worker repository 是共享数据源，CDP 与模型访问是并列适配器。
+
+**source 断联时移除 realm 树。** 拒绝，因为传输中断会丢失最后一份有用拓扑，并折叠用户在 Elements 中的检查状态。继续使用旧 object handle 同样不可接受：新的连接 generation 无法证明任何先前实时对象仍然存在。
+
+## Verification
+
+- 同一个 collector 实现能从等价 Cordis 运行时生成 Host 和 Client 快照。
+- Elements 显示 `<host>` 与 `<clients>/<client>` container，每个 realm 的 root Context 直接位于其 container 下。
+- Context element 不含 attribute；Fiber element 只暴露 Cordis `uid`；root Fiber 不出现。
+- 每个 connected Context 与 Fiber 都有一个连接本地 frontend node id、一个 Worker backend node id 和一个可解析的连接本地 Runtime object id，且它们都不作为 attribute 暴露。
+- `DOM.resolveNode` 与 `DOM.requestNode` 能往返映射 Context/Fiber 身份，且不会跨 DevTools 连接或 source generation 共享 object id。
+- Runtime evaluation 返回的 Context 或 Fiber 会被标记为 node，并能在 Elements 中定位。
+- 断联会销毁 Client execution context 与 RemoteObject，同时原样保留最后一棵 Elements 树；新的 transport generation 在完整 snapshot 到达后替换它。
+- 重连和 resnapshot 会重放最新树状态；无变化的 snapshot 不发送 DOM mutation，结构变化只更新受影响的 parent 或 node。畸形或超限 replacement 不会替换最后一个有效快照。
+- 存储的 snapshot 与查询 API 不包含 CDP 类型，可以不加修改地支持未来的模型适配器。
+
+## Consequences
+
+Cordis 不提供完整的全局 Context registry。collector 能恢复从 live fiber 与 event hook 可达的 Context；一个已创建、从未使用且只由应用代码保留的 Context 会有意缺席。
+
+需要语义识别的每个 Host object 都会增加一次 Runtime round trip。annotation 失败时保留普通 RemoteObject，不破坏 Runtime 或 Debugger 投递。Client Console observation 保留原始 method result，并在之后调度序列化；每个已启用 DevTools session 独立保留 handle，因此识别既不阻塞页面调用，也不在连接间共享对象。
+
+source 仍发布完整 snapshot，从而复用同一套 Host/Client collector，并能在 observation 丢失后恢复。Worker 承担 snapshot 比较成本，再发送增量 CDP DOM mutation，使无变化的 revision 不会重置 Elements document。节点数与字节数限制会保留有效前缀并报告截断；以后可以替换 source delta 协议，而不修改 snapshot model 或 CDP projection。
+
+对象表会有意强引用当前可见树中的每个对象，直到下一次 replacement 或 observer dispose。该集合受保留快照限制，不能扩展成通用对象注册表。
+

+# Agent Note: Rename code-mode to ptc — the transport is named PTC, user-facing copy says PTC mode
+
+Status: implemented
+
+English | [中文](2026-08-25-rename-code-mode-to-ptc.zh.md)
+
+## Problem
+
+The tool-registry presentation mode that exposes tools through a generated SDK and the `run_code` transport shipped under the name Code Mode, while the client preset that selects it already shipped as "PTC mode" (locale `presetPtcName: 'PTC mode'`, zh `PTC 模式`). One feature had two names: config values, plugin and event names, files, and documentation said `code`/`code-mode`, and the user-facing name said "PTC mode". A pre-release rename must update every reference together — no compatibility aliases.
+
+## Decision
+
+The feature is renamed to PTC (programmatic tool calls). Code identifiers use `ptc` — the transport is not a sibling of plan-mode, so the identifier does not carry `-mode`. User-facing prose keeps "PTC mode" (EN) / "PTC 模式" (zh), matching the shipped preset name.
+
+Renamed in this PR:
+
+- config value `tools.mode: 'code'` → `'ptc'` (`ToolPresentationMode` and the zod unions in `dsh-tools` and `dsh-agent-tool-presentation`)
+- preset directory `presets/code/` → `presets/ptc/` (preset id `ptc`)
+- source and test files `code-mode.ts` → `ptc.ts` and friends; root demo `demo:code-mode` → `demo:ptc` (`scripts/demo-ptc.mjs`)
+- the dispatch waterfall `tools/code-dispatch-log` → `tools/ptc-dispatch-log` and types `CodeDispatch*` → `PtcDispatch*`
+- prompt rule `tools:code-only` → `tools:ptc-only`
+- prose "Code Mode" → "PTC mode" / "PTC 模式" in docs, READMEs, and the eight implemented Agent Notes whose topic names the feature (those files were renamed in place)
+
+Deferred to the stacked persistence PR: the session-persistent vocabulary — the durable event types `tool/code-dispatch` / `tool/code-dispatch-start`, the logged plugin name `tools-code-mode`, and the sub-call id segment `:code:`. That PR is blocked until the `SESSION_FORMAT_VERSION` v0→v1 migration lands with it.
+
+Kept unchanged: `run_code` and its `code` parameter (they name the program payload, not the mode), `CodeSdkLanguage`, `CodeRunFailedError`, the `dsh-code-runtime*` package family, the third-party `codex-code-mode-host` binary name, and every frozen archived note.
+
+## Alternatives considered
+
+- **`ptc-mode` identifiers** — rejected: PTC is a tool-presentation transport, not a mode in the plan-mode sense, and the identifier should not claim that kinship.
+- **Surface-only rename** — rejected: the pre-release stance updates every reference together.
+- **Renaming `run_code` too** — rejected: the tool name describes running a program, not the mode, and is model-facing API surface.
+- **Renaming the durable event vocabulary in this PR** — rejected: renaming `tool/code-dispatch*` without a format bump would make pre-rename session logs unreadable; that rename belongs to the stacked persistence PR that lands together with the v0→v1 migration.
+
+## Consequences
+
+Configs with `mode: code` and preset ids `code` are unsupported on this build. The session-persistent vocabulary still says `tool/code-dispatch*`, `tools-code-mode`, and `:code:`, so existing session logs load unchanged and no `SESSION_FORMAT_VERSION` bump is needed yet. The stacked persistence PR renames that vocabulary and is blocked until the v0→v1 migration lands with it (the version mechanics are the [session-event-vocabulary note](../simplification/2026-08-25-fail-closed-session-event-vocabulary.md)). Keyless snapshot refreshes carry this PR's vocabulary; the persistence PR refreshes the dispatch-bearing fixtures. The shipped decision this note renames is [the PTC foundation note](../feature/2026-06-15-ptc.md).

+# Agent Note: 将 code-mode 重命名为 ptc——传输层命名为 PTC，用户文案使用 PTC mode
+
+Status: implemented
+
+[English](2026-08-25-rename-code-mode-to-ptc.md) | 中文
+
+## 问题
+
+通过生成的 SDK 与 `run_code` 传输层向模型呈现工具的注册表模式，发布时用的名字是 Code Mode；而选择该模式的客户端预设早已以「PTC mode」发布（locale `presetPtcName: 'PTC mode'`，中文 `PTC 模式`）。同一功能有两套名字：配置值、插件与事件名、文件与文档写的是 `code`／`code-mode`，用户可见的名字却是「PTC mode」。预发布阶段的更名必须一次性更新所有引用——不加任何兼容别名。
+
+## 决策
+
+该功能更名为 PTC（programmatic tool calls，程序化工具调用）。代码标识符使用 `ptc`——该传输层并非 plan-mode 的同类模式，因此标识符不带 `-mode`。用户可见文案沿用「PTC mode」（英文）／「PTC 模式」（中文），与已发布的预设名一致。
+
+本 PR 完成的重命名包括：
+
+- 配置值 `tools.mode: 'code'` → `'ptc'`（`ToolPresentationMode` 以及 `dsh-tools`、`dsh-agent-tool-presentation` 中的 zod union）
+- 预设目录 `presets/code/` → `presets/ptc/`（预设 id 为 `ptc`）
+- 源文件与测试文件 `code-mode.ts` → `ptc.ts` 等；根 demo `demo:code-mode` → `demo:ptc`（`scripts/demo-ptc.mjs`）
+- 分发 waterfall `tools/code-dispatch-log` → `tools/ptc-dispatch-log`，类型 `CodeDispatch*` → `PtcDispatch*`
+- 提示词规则 `tools:code-only` → `tools:ptc-only`
+- 文档、README 与八个以该功能命名的 implemented Agent Note 中的文案 "Code Mode" → "PTC mode"／"PTC 模式"（这些 Note 文件一并就地改名）
+
+延后到堆叠的持久化 PR：会话持久词汇——持久事件类型 `tool/code-dispatch`／`tool/code-dispatch-start`、日志中的插件名 `tools-code-mode`、子调用 id 段 `:code:`。该 PR 被阻塞，直到 `SESSION_FORMAT_VERSION` v0→v1 迁移与其一同落地。
+
+保持不变：`run_code` 及其 `code` 参数（它们描述程序载荷，而非模式）、`CodeSdkLanguage`、`CodeRunFailedError`、`dsh-code-runtime*` 包族、第三方二进制名 `codex-code-mode-host`，以及所有冻结的 archived Note。
+
+## 备选方案
+
+- **使用 `ptc-mode` 标识符**——否决：PTC 是工具呈现传输层，不是 plan-mode 意义上的模式，标识符不应宣示这种亲缘关系。
+- **仅重命名表面**——否决：预发布立场要求一次性更新所有引用。
+- **连 `run_code` 一起改名**——否决：该工具名描述的是运行程序，不是模式，而且是对模型可见的 API 表面。
+- **在本 PR 中一并重命名持久事件词汇**——否决：在没有格式版本提升的情况下重命名 `tool/code-dispatch*` 会让更名前的会话日志无法读取；该重命名属于与 v0→v1 迁移一同落地的堆叠持久化 PR。
+
+## 后果
+
+配置中写 `mode: code`、预设 id 为 `code`，在本构建上不再受支持。会话持久词汇仍为 `tool/code-dispatch*`、`tools-code-mode` 与 `:code:`，因此既有会话日志照常读取，无需 `SESSION_FORMAT_VERSION` 提升。堆叠的持久化 PR 负责重命名该词汇，并被阻塞到 v0→v1 迁移与其一同落地（版本机制见 [session event 词汇 Note](../simplification/2026-08-25-fail-closed-session-event-vocabulary.zh.md)）。无密钥的 snapshot refresh 携带本 PR 的词汇；持久化 PR 刷新包含分发的夹具。本 Note 所更名的已发布决策是 [PTC 基础 Note](../feature/2026-06-15-ptc.zh.md)。

+# Agent Note: Inspector execution realms and protocol planes
+
+Status: implemented
+
+English | [中文](2026-08-26-inspector-execution-realms-and-protocol-planes.zh.md)
+
+## Problem
+
+The Inspector package executes code in three JavaScript environments: the browser Client, the Host Node main thread, and an Inspector Worker thread. Without execution-oriented directories, feature names alone do not establish where code runs or which identifiers it may own.
+
+This ambiguity is risky because Host and Client support intentionally differs while their architecture must remain comparable. Host Runtime and Debugger delegate to Node's inspector protocol; Client Runtime and Console simulate the same backend semantics over an internal bridge. If their files, interfaces, and unsupported operations diverge structurally, each new protocol method encourages a second routing model. Likewise, consumers that only need the Cordis runtime tree must not inherit debugger activation, Chrome connection state, or CDP identifiers.
+
+The [cross-realm CDP inspector decision](2026-08-23-cross-realm-cdp-inspector.md) owns Worker, transport, Runtime, debugger, and security behavior. The [Cordis runtime tree inspection decision](2026-08-24-cordis-runtime-tree-inspection.md) owns Cordis tree semantics, object routing, and DOM projection. This decision owns source placement, dependency direction, and the separation between domain data, backend semantics, internal transport, and Chrome CDP state.
+
+## Decision
+
+Top-level source directories identify execution ownership. `client/` contains only browser Client code, `host/` only Host Node-main-thread code, `worker/` only Worker-thread code, and `shared/` code that is safe in every environment. A module that executes in the Worker on behalf of a Client belongs under `worker/`, not `client/`.
+
+The repository-required `src/index.ts` and `src/invariant.ts` discovery entries are the only root-level source exceptions. They expose the Host package entry and its service type or register the invariant companion, contain no Inspector runtime implementation, and remain at fixed paths for repository tooling.
+
+```text
+src/
+  shared/   environment-independent data and interfaces
+  client/   browser Client producer and adapters
+  host/     Host Node-main-thread producer and adapters
+  worker/   Worker transport, repositories, realm backends, and CDP endpoint
+```
+
+`client/` and `host/` have the same relative directories and filenames. Their common roles are plugin entry, bridge lifecycle and RPC, Cordis and network inspection, and CDP-oriented Runtime, Console, Debugger, Sources, Profiler, and HeapProfiler adapters. Support may differ: an unavailable operation remains in the corresponding mirrored module and returns the shared capability-unavailable or typed-unsupported result. Mirroring standardizes where a capability is implemented; it does not claim equal engine support.
+
+Worker-side realm adapters use the same rule under `worker/realms/client/` and `worker/realms/host/`. These adapters normalize Client simulation and Node inspector behavior behind shared CDP-oriented backend interfaces. They do not own Chrome wire messages or connection-local CDP identifiers.
+
+## Execution ownership
+
+`client/` owns page-realm observation, Client object handles, browser evaluation, browser Console interception, Client source publication, and its direct authenticated bridge to the Worker. It may use browser APIs but not Node or Worker implementation modules.
+
+`host/` owns Cordis plugin composition on the Node main thread, Worker startup and disposal, Host object observation, fetch capture, Node inspector notification forwarding, and the Host side of the Worker bridge. It may use Node APIs but does not construct Chrome CDP responses.
+
+`worker/bridge/` owns source admission, transport endpoints, connection generations, frame dispatch, correlation, and routing between source producers and Worker consumers. `worker/inspection/` owns retained Cordis and network observations plus transport-independent queries. `worker/realms/` owns the normalized Host and Client runtime backends. `worker/cdp/` owns HTTP discovery, DevTools sessions, Chrome method dispatch, domain enable state, and every connection-local Chrome identifier.
+
+The Worker remains the sole Chrome CDP wire and state owner. Client code simulates shared backend operations, not the CDP wire. Host code delegates supported backend operations to Node inspector, but Node protocol identifiers are translated inside the Worker Host realm before common domain projection.
+
+## Data and identifier ownership
+
+`shared/cordis/` contains the CDP-independent semantic model, immutable snapshots, collection and observation, realm-local object registration, projections, and reader interfaces. `model.ts` contains no transport handles or CDP identifiers. `snapshot.ts` may carry a realm-local opaque object reference because a live object query needs that route, but consumers can project it away.
+
+`shared/network/` contains fetch and network observations, captured body representation, and header normalization. These records describe observed activity and do not contain CDP request ids or domain enable state.
+
+`shared/cdp/` contains normalized backend interfaces and values for realm capabilities, Runtime, Console, Debugger, Sources, Profiler, HeapProfiler, and typed unsupported results. Backend handles in these interfaces are opaque and realm-owned. They are not Chrome `RemoteObjectId`, `ExecutionContextId`, `ScriptId`, or `CallFrameId` values.
+
+`shared/bridge/` contains the versioned internal carrier: source and generation identifiers, envelopes, codecs, validation, bounded publication, RPC correlation, dispatch interfaces, and domain-specific message unions. Its message modules may transport Cordis snapshots, network observations, Console events, Runtime operations, source reads, debugger operations, and semantic queries without turning those values into CDP messages.
+
+`worker/cdp/ids.ts` is the only owner of Chrome connection-local identifiers such as `RemoteObjectId`, `ExecutionContextId`, `ScriptId`, `NodeId`, and `CallFrameId`. Worker domain sessions allocate and release them and map them to realm backend handles or inspection records. Source, generation, sequence, request, Cordis Fiber uid, realm object reference, backend handle, and Chrome id remain distinct types because their owners and lifetimes differ.
+
+## Dependency rules
+
+The domain modules `shared/cordis/`, `shared/network/`, and `shared/cdp/` do not import `shared/bridge/` or any execution-specific directory. `shared/bridge/` may import those domain types when defining internal messages. No module under `shared/` imports Node-only or browser-only APIs.
+
+Top-level `client/` and `host/` import `shared/` but never each other or `worker/`. Equivalent roles use equivalent shared interfaces. Environment-specific transport and engine behavior stays in the mirrored implementation file rather than entering a shared conditional implementation.
+
+`worker/realms/` and `worker/inspection/` import shared interfaces but do not import `worker/cdp/`; normalized backend results and stored observations cannot contain Chrome connection state. `worker/cdp/` may consume realm and inspection interfaces to project CDP. `worker/bridge/` routes shared messages and invokes Worker services without becoming an owner of Cordis, network, Runtime, or Chrome state.
+
+The package remains one `@deepseek-ai/dsh-experimental-inspector` package with explicit Client and Host compiler faces. Directory separation is an execution and dependency rule, not a package split.
+
+## Verification
+
+- Every runtime implementation has an unambiguous execution owner through `shared/`, `client/`, `host/`, or `worker/`; only the repository-required package and invariant forwarding entries remain at the source root.
+- Top-level Client and Host trees, and Worker Client and Host realm trees, have identical relative implementation paths; unequal capability support is explicit and typed.
+- Cordis and network readers are usable without importing debugger, source, transport, or CDP session modules.
+- Internal messages contain source-level identities and validated domain values but no Chrome connection-local ids.
+- Normalized realm backend interfaces support Host delegation and Client simulation without either implementation constructing Chrome CDP messages.
+- Only Worker CDP modules allocate Chrome ids and own DevTools connection enable, object, script, node, and call-frame state.
+- Host Runtime and debugging, Client Runtime and Console, Network capture, Cordis Elements projection, disconnect retention, and semantic query behavior have focused coverage.
+- Compiler faces, import checks, and the structural layout test reject environment leaks and Client/Host mirror drift.
+
+## Alternatives considered
+
+**Organize every file by feature domain.** Rejected because a Runtime or Cordis feature spans three environments with different available APIs. Feature-only paths conceal execution constraints and make accidental browser-to-Node imports difficult to review.
+
+**Put Worker Client and Host adapters in top-level `client/` and `host/`.** Rejected because those adapters execute in the Worker and own different resources from page and Node-main-thread producers. A directory name must answer where code runs before it answers which remote realm it represents.
+
+**Allow Client and Host trees to contain only currently supported files.** Rejected because asymmetric layout obscures missing capability decisions and lets equivalent routing roles acquire unrelated interfaces. Explicit unsupported implementations keep evolution exhaustive without pretending support exists.
+
+**Keep one shared protocol directory.** Rejected because internal carrier identities, Cordis semantic data, normalized Runtime values, and Chrome wire identifiers have different consumers and lifetimes. A single directory encourages domain models to depend on transport and CDP presentation.
+
+**Split Client, Host, protocol, and Worker into separate packages.** Rejected for the experimental phase. The deployment unit remains one Client/Host Cordis plugin, and package boundaries would add build and release coordination without improving the required execution separation.
+
+## Consequences
+
+Exact mirroring adds small adapter files for unsupported capabilities. Those files are intentional compatibility points between implementations, but they must stay thin and must not manufacture fake behavior.
+
+Moving types without changing behavior can still expose hidden dependency cycles, especially where Runtime object annotation reaches Cordis repositories. The dependency rules require inversion through shared interfaces rather than a temporary import from a lower-level module.
+
+`shared/cdp/` can become a second copy of the Chrome protocol if normalized types are added indiscriminately. A shared type belongs there only when both realm implementations or a common Worker projector consume it; Chrome session bookkeeping and wire-only fields remain under `worker/cdp/`.
+
+Explicit Client and Host compiler faces and focused behavior tests add maintenance work, but they keep environment leaks and mirror drift visible.

+# Agent Note: Inspector 执行环境与协议平面
+
+Status: implemented
+
+[English](2026-08-26-inspector-execution-realms-and-protocol-planes.md) | 中文
+
+## Problem
+
+Inspector 包的代码运行在三个 JavaScript 环境中：浏览器 Client、Host Node 主线程和 Inspector Worker thread。只按功能命名目录时，文件路径无法说明代码在哪里运行，也无法说明它可以持有哪些标识符。
+
+这种含糊会带来风险，因为 Host 与 Client 的支持能力有意不同，但架构必须保持可比较。Host Runtime 与 Debugger 委托 Node inspector protocol；Client Runtime 与 Console 通过内部 bridge 模拟同一套 backend 语义。如果两边的文件、接口与 unsupported operation 在结构上分叉，每增加一种协议方法都容易产生第二套路由模型。同样，只需要 Cordis 运行时树的消费方不应继承 debugger activation、Chrome 连接状态或 CDP 标识符。
+
+现有的[跨 realm CDP Inspector 决策](2026-08-23-cross-realm-cdp-inspector.zh.md)负责 Worker、transport、Runtime、debugger 与安全行为。[Cordis 运行时树检查决策](2026-08-24-cordis-runtime-tree-inspection.zh.md)负责 Cordis 树语义、对象路由与 DOM projection。本决策负责源码位置、依赖方向，以及领域数据、backend 语义、内部 transport 和 Chrome CDP 状态之间的分隔。
+
+## Decision
+
+顶层源码目录标识执行归属。`client/` 只包含浏览器 Client 代码，`host/` 只包含 Host Node 主线程代码，`worker/` 只包含 Worker thread 代码，`shared/` 只包含在所有环境中都安全的代码。即使某个模块代表 Client，只要它实际在 Worker 中执行，就仍属于 `worker/`，而不是 `client/`。
+
+仓库要求的 `src/index.ts` 与 `src/invariant.ts` 发现入口是仅有的源码根目录例外。它们暴露 Host package entry 及其 service type，或注册 invariant companion，不包含 Inspector 运行时实现，并为仓库工具保留在固定路径。
+
+```text
+src/
+  shared/   environment-independent data and interfaces
+  client/   browser Client producer and adapters
+  host/     Host Node-main-thread producer and adapters
+  worker/   Worker transport, repositories, realm backends, and CDP endpoint
+```
+
+`client/` 与 `host/` 拥有相同的相对目录和文件名。共同角色包括 plugin entry、bridge lifecycle 与 RPC、Cordis 和 network inspection，以及面向 CDP 的 Runtime、Console、Debugger、Sources、Profiler 和 HeapProfiler adapter。支持程度可以不同：不可用的操作仍保留在对应的镜像模块中，并返回共享的 capability-unavailable 或类型化 unsupported 结果。镜像结构统一的是能力实现位置，而不是宣称两个引擎支持相同功能。
+
+Worker 侧 realm adapter 在 `worker/realms/client/` 与 `worker/realms/host/` 下遵守相同规则。这些 adapter 通过共享的面向 CDP backend 接口规范化 Client 模拟行为与 Node inspector 行为。它们不拥有 Chrome wire message 或连接局部的 CDP 标识符。
+
+## Execution ownership
+
+`client/` 负责 page realm observation、Client object handle、浏览器求值、浏览器 Console interception、Client source publication 以及到 Worker 的直接鉴权 bridge。它可以使用浏览器 API，但不能导入 Node 或 Worker 实现模块。
+
+`host/` 负责 Node 主线程上的 Cordis plugin composition、Worker 启动与 dispose、Host object observation、fetch capture、Node inspector notification forwarding，以及 Worker bridge 的 Host 一侧。它可以使用 Node API，但不构造 Chrome CDP response。
+
+`worker/bridge/` 负责 source admission、transport endpoint、connection generation、frame dispatch、correlation，以及 source producer 与 Worker consumer 之间的路由。`worker/inspection/` 负责保留的 Cordis 与 network observation，以及不依赖 transport 的 query。`worker/realms/` 负责规范化的 Host 与 Client runtime backend。`worker/cdp/` 负责 HTTP discovery、DevTools session、Chrome method dispatch、domain enable 状态与所有连接局部的 Chrome 标识符。
+
+Worker 继续作为唯一的 Chrome CDP wire 与状态 owner。Client 代码模拟共享 backend operation，而不是模拟 CDP wire。Host 代码把支持的 backend operation 委托给 Node inspector，但 Node protocol 标识符在 Worker Host realm 内转换后才进入公共 domain projection。
+
+## Data and identifier ownership
+
+`shared/cordis/` 包含与 CDP 无关的语义模型、不可变 snapshot、collection 与 observation、realm-local object registration、projection 与 reader interface。`model.ts` 不包含 transport handle 或 CDP 标识符。`snapshot.ts` 可以携带 realm-local opaque object reference，因为实时对象查询需要该路由信息，但消费方可以在 projection 中移除它。
+
+`shared/network/` 包含 fetch 与 network observation、采集 body 表示及 header normalization。这些记录描述已观测活动，不包含 CDP request id 或 domain enable 状态。
+
+`shared/cdp/` 包含 realm capability、Runtime、Console、Debugger、Sources、Profiler、HeapProfiler 的规范化 backend 接口和值，以及类型化 unsupported 结果。这些接口中的 backend handle 是不透明且由 realm 持有的。它们不是 Chrome `RemoteObjectId`、`ExecutionContextId`、`ScriptId` 或 `CallFrameId`。
+
+`shared/bridge/` 包含带版本的内部 carrier：source 与 generation 标识符、envelope、codec、validation、有限 publication、RPC correlation、dispatch interface 及分领域的 message union。其 message 模块可以传输 Cordis snapshot、network observation、Console event、Runtime operation、source read、debugger operation 与语义 query，但不会把这些值转换成 CDP message。
+
+`worker/cdp/ids.ts` 是 Chrome 连接局部标识符的唯一 owner，包括 `RemoteObjectId`、`ExecutionContextId`、`ScriptId`、`NodeId` 与 `CallFrameId`。Worker domain session 分配并释放这些 id，把它们映射到 realm backend handle 或 inspection record。source、generation、sequence、request、Cordis Fiber uid、realm object reference、backend handle 与 Chrome id 必须保持为不同类型，因为它们的 owner 和生命周期不同。
+
+## Dependency rules
+
+领域模块 `shared/cordis/`、`shared/network/` 与 `shared/cdp/` 不导入 `shared/bridge/` 或任何执行环境专属目录。`shared/bridge/` 在定义内部 message 时可以导入这些领域类型。`shared/` 下的任何模块都不导入 Node-only 或 browser-only API。
+
+顶层 `client/` 与 `host/` 可以导入 `shared/`，但不能互相导入，也不能导入 `worker/`。等价角色使用等价的共享接口。环境专属 transport 与 engine 行为保留在对应镜像实现文件中，不进入带条件分支的共享实现。
+
+`worker/realms/` 与 `worker/inspection/` 可以导入共享接口，但不导入 `worker/cdp/`；规范化 backend result 和已存 observation 不能包含 Chrome connection state。`worker/cdp/` 可以消费 realm 与 inspection interface 来生成 CDP projection。`worker/bridge/` 路由共享 message 并调用 Worker service，但不成为 Cordis、network、Runtime 或 Chrome 状态的 owner。
+
+本能力继续保留在同一个 `@deepseek-ai/dsh-experimental-inspector` 包中，并使用显式 Client 与 Host compiler face。目录分隔是执行与依赖规则，不是拆包方案。
+
+## Verification
+
+- 每个运行时实现都通过 `shared/`、`client/`、`host/` 或 `worker/` 拥有明确的执行 owner；只有仓库要求的 package 与 invariant 转发入口留在源码根目录。
+- 顶层 Client/Host 树与 Worker Client/Host realm 树分别拥有相同的相对实现路径；不同能力支持使用显式类型表示。
+- Cordis 与 network reader 无需导入 debugger、source、transport 或 CDP session 模块即可使用。
+- 内部 message 包含 source 层 identity 与已验证领域值，但不包含 Chrome 连接局部 id。
+- 规范化 realm backend interface 同时支持 Host 委托与 Client 模拟，且两种实现都不构造 Chrome CDP message。
+- 只有 Worker CDP 模块分配 Chrome id，并持有 DevTools 连接的 enable、object、script、node 与 call-frame 状态。
+- Host Runtime 与 debugging、Client Runtime 与 Console、Network capture、Cordis Elements projection、断联保留与语义 query 行为均有聚焦测试覆盖。
+- compiler face、import check 与结构测试能够拒绝环境泄漏和 Client/Host 镜像漂移。
+
+## Alternatives considered
+
+**所有文件都按功能领域组织。** 拒绝，因为一个 Runtime 或 Cordis 功能会跨越三个可用 API 不同的环境。只有功能信息的路径会隐藏执行限制，也让 browser 到 Node 的意外导入难以审查。
+
+**把 Worker Client 与 Host adapter 放入顶层 `client/` 和 `host/`。** 拒绝，因为这些 adapter 实际运行在 Worker 中，持有的资源也不同于 page 与 Node 主线程 producer。目录名应先回答代码在哪里运行，再回答它代表哪个远端 realm。
+
+**Client 与 Host 目录只保留当前支持的文件。** 拒绝，因为不对称目录会隐藏缺失能力决策，并允许等价路由角色形成无关接口。显式 unsupported 实现既保证穷尽演进，也不虚构已支持行为。
+
+**保留一个共享 protocol 目录。** 拒绝，因为内部 carrier identity、Cordis 语义数据、规范化 Runtime value 与 Chrome wire identifier 的消费方和生命周期不同。单一目录会诱导领域模型依赖 transport 和 CDP presentation。
+
+**把 Client、Host、protocol 与 Worker 拆成多个包。** 实验阶段拒绝。部署单元仍是一个 Client/Host Cordis plugin；包边界会增加构建和发布协作，却不能改善所需的执行环境分隔。
+
+## Consequences
+
+严格镜像会为不支持的能力增加小型 adapter 文件。这些文件是两个实现之间有意保留的兼容点，但必须保持轻薄，也不能制造虚假行为。
+
+即使只移动类型而不改变行为，也可能暴露隐藏的依赖环，尤其是 Runtime object annotation 访问 Cordis repository 的位置。依赖规则要求通过共享接口反转依赖，不能临时从较低层模块反向导入。
+
+如果不加约束地添加规范化类型，`shared/cdp/` 可能变成第二份 Chrome protocol。只有两个 realm 实现或公共 Worker projector 会消费的类型才属于这里；Chrome session bookkeeping 与 wire-only field 保留在 `worker/cdp/`。
+
+显式 Client/Host compiler face 与聚焦行为测试增加了维护工作，但会持续暴露环境泄漏和镜像结构漂移。
