+# Mod prompt.submit in headless runs
+
+Design: [docs/design/2026-10-30-mod-prompt-submit.md](../../docs/design/2026-10-30-mod-prompt-submit.md).
+
+## Setup
+
+- Build the CLI and bundle it: `npm run build && npm run bundle`.
+- Use an isolated `HOME` whose `.qwen/settings.json` sets `experimental.mods` to `true`, selects `openai` auth and points `OPENAI_BASE_URL` at a loopback OpenAI-compatible fixture that answers `OK` and records every request.
+- Install a guard Mod with `qwen extensions install ./guard-mod --consent`. Its `hooks/register.js`:
+
+```javascript
+export function register(on) {
+  on('prompt.submit', async ($, e, next) => {
+    $.ui.log('submit:' + JSON.stringify(e));
+    if (/AKIA[0-9A-Z]{16}/.test(e.text)) return { drop: 'the prompt holds an AWS access key' };
+    if (e.text === 'boom') throw new Error('guard broke');
+    if (e.text === 'mine') return { text: 'answered without next' };
+    const entered = await next({
+      ...e,
+      text: e.text.replace(/\bprod\b/g, 'production'),
+      context: [
+        ...(e.context ?? []),
+        e.text.startsWith('note') ? 'Mod note: ' + e.text : 'Mod context: <be brief>',
+      ],
+    });
+    $.ui.log('entered:' + JSON.stringify(entered));
+    return entered;
+  }).catch(($, e, next) => (next.called ? next(e) : { drop: 'the guard failed' }));
+  on('turn.start', ($, e, next) => {
+    $.ui.log('turn.start:' + e.text);
+    return next(e);
+  });
+}
+```
+
+## Test groups
+
+### Rewrite and context
+
+- `qwen -p 'deploy prod now' --output-format json`: exit 0. The model reads `deploy production now` followed by the hidden block `Mod context: &lt;be brief&gt;`. `turn.start` hears `deploy production now`. The transcript user record has `displayText: "deploy production now"` and the block as `hookContext`.
+
+### Drop
+
+- `qwen -p 'key AKIAABCDEFGHIJKLMNOP' --output-format json`: exit 1, no model request, error result `Prompt dropped by a hook: the prompt holds an AWS access key`.
+- The same prompt in text output: exit 1, the reason on stderr.
+- `-p boom`, where the guard throws and its `.catch` drops: exit 1, no model request, `Prompt dropped by a hook: the guard failed`.
+- `-p mine`, where the guard answers without `next`: exit 1, no model request, `Prompt not submitted: a hook answered without passing the prompt on`.
+
+### stream-json
+
+- A message holding a key, then `ship prod`: the first message ends with the error result, the session goes on, and the second reaches the model as `ship production`.
+- A message `[text 'ship prod', image block]`: the model reads `ship production` with the serialized image block after it, and the transcript `displayText` keeps the block after the rewritten text, the same shape it has without a rewrite.
+
+### Context sent once per context
+
+Add a settings `UserPromptSubmit` command hook that prints `settings-note`, then send `note one`, `note two`, `note two` in one stream-json session:
+
+- `note one`: block `Mod note: note one\n\nsettings-note`.
+- `note two`: block `Mod note: note two` only; the unchanged `settings-note` is not sent again.
+- `note two` again: no block; both contexts are already in the conversation.
+
+## Results (2026-11-02, branch head after merging main)
+
+Built CLI, real fixture server, all groups above pass:
+
+| Run | Result |
+| --- | --- |
+| rewrite (json) | exit 0, model reads `deploy production now` + context block, transcript `displayText` rewritten |
+| drop (json / text) | exit 1, 0 model requests, drop reason as error result / on stderr |
+| guard throws, `.catch` drops | exit 1, 0 model requests, `the guard failed` |
+| answer without `next` | exit 1, 0 model requests, `Prompt not submitted: ...` |
+| stream-json drop then rewrite | first message error, second sent as `ship production` |
+| stream-json rewrite with an image block | transcript `displayText` = `ship production\n{"type":"image",...}` |
+| context sent once per context | blocks `["Mod note: note one\n\nsettings-note"]`, `["Mod note: note two"]`, `[]` |
+
+## Baseline
+
+`main` at `619a601b39`, bundled locally, skips every `prompt.submit` hook at startup (`Hooks for unsupported events will not run: prompt.submit`): the key prompts reach the model with exit 0, and `turn.start` hears the original text. The global `qwen` 0.25.1 on this machine is a standalone binary, which the fixture driver (it starts the CLI with `node`) cannot run, so the baseline comes from the `main` bundle.

+- Adds an "Add to Split View" option to eligible sidebar session menus in web shell, making it easier to open sessions side by side. ([#15956](https://github.com/QwenLM/qwen-code/pull/15956)) by @4ekuct25
+- Adds request success rate, output speed, per-model success indicators, and distinct model colors to the Web Shell token usage panel. ([#16108](https://github.com/QwenLM/qwen-code/pull/16108)) by @qqqys
+- Web Shell composer shows a dismissible Workflow chip that turns Workflow mode off, warns when tools are unavailable, and summarizes the mode in the + menu. ([#16107](https://github.com/QwenLM/qwen-code/pull/16107)) by @qqqys
+- Web Shell Token Usage now plots per-request output speed, first-token latency, and failure details by model, making session performance and errors easier to inspect. ([#16111](https://github.com/QwenLM/qwen-code/pull/16111)) by @qqqys
+- With experimental.unifiedAgentLoop enabled, more ACP turns, including channel prompts and Goal-proposal approvals, run on the shared loop. ([#15902](https://github.com/QwenLM/qwen-code/pull/15902)) by @qqqys
+- Mods can now run prompt.submit hooks in headless runs for -p prompts and stream-json user messages, allowing prompt inspection or rewriting before submission. ([#15905](https://github.com/QwenLM/qwen-code/pull/15905)) by @qqqys
+- Desktop releases now publish Fedora 44 and RHEL 10 x64 RPM installers alongside existing Linux packages. ([#16060](https://github.com/QwenLM/qwen-code/pull/16060)) by @yiliang114
+- feat(web-shell): make GitHub channel configuration usable ([#16096](https://github.com/QwenLM/qwen-code/pull/16096)) by @wenshao
+- feat(verify-pr): inherit --publish consent on same-session re-verification ([#16112](https://github.com/QwenLM/qwen-code/pull/16112)) by @wenshao
+- feat(ci): let the PR review canary cohort carry its own endpoint ([#16130](https://github.com/QwenLM/qwen-code/pull/16130)) by @yiliang114
+
+#### Bug Fixes

+- OAuth refresh lock cleanup now removes the lock only when the current process owns it, preventing exiting processes from deleting active refresh locks. ([#15661](https://github.com/QwenLM/qwen-code/pull/15661)) by @2SinceJuly
+- MCP tool discovery now skips duplicate tool names but keeps all uniquely named tools, preventing one name collision from hiding an entire server's tools. ([#15757](https://github.com/QwenLM/qwen-code/pull/15757)) by @2SinceJuly
+- The Web Shell Plugins page now shows a back control when the navigation rail is unavailable, letting users return to chat from compact layouts. ([#15651](https://github.com/QwenLM/qwen-code/pull/15651)) by @2SinceJuly
+- LSP code-navigation queries now fail with an explicit reason when no language server is ready instead of returning empty results. ([#15946](https://github.com/QwenLM/qwen-code/pull/15946)) by @404khai
+- The verify report now counts targeted gate test-suite results separately from a round's scripted assertions, making assertion totals reflect only round checks. ([#16013](https://github.com/QwenLM/qwen-code/pull/16013)) by @wenshao
+- Makes long /btw answers scroll in a bounded panel with mouse wheel, Shift+Up/Down, PageUp/PageDown, and a scrollbar, while short answers remain unchanged. ([#15982](https://github.com/QwenLM/qwen-code/pull/15982)) by @2SinceJuly
+- Fixes verify-pr to count each suite run as one assertion and handle skip notices on closed PRs so review rounds are not rejected with zero assertions. ([#16050](https://github.com/QwenLM/qwen-code/pull/16050)) by @wenshao
+- Fixes Kimi K3 generation recognition so supported IDs use the 1,000,000-token context window, while k3-256k keeps its 256K window. ([#16048](https://github.com/QwenLM/qwen-code/pull/16048)) by @wenshao
+- Fixes review command so plain-language re-review requests target the intended PR and do not misread resume flags or file-like tokens. ([#15998](https://github.com/QwenLM/qwen-code/pull/15998)) by @wenshao
+- Installs DejaVu fonts in the sandbox so capture cards use the intended monospace font and render legibly. ([#16032](https://github.com/QwenLM/qwen-code/pull/16032)) by @yiliang114
+- Moves the Workflow mode toggle from the composer toolbar into the composer “+” menu to reduce toolbar clutter while keeping it accessible. ([#16047](https://github.com/QwenLM/qwen-code/pull/16047)) by @qqqys
+- Improves managed-agent recovery accuracy by blocking gap fills without child ledger evidence and clarifying unknown or never-started states. ([#16015](https://github.com/QwenLM/qwen-code/pull/16015)) by @wenshao
+- Fixes managed-agent child result delivery status so consumed child results are no longer marked pending. ([#16074](https://github.com/QwenLM/qwen-code/pull/16074)) by @wenshao
+- Fixes AI attribution notes for loosely spelled git commit --amend commands so they diff against the amended commit, not earlier commits. ([#16073](https://github.com/QwenLM/qwen-code/pull/16073)) by @yiliang114
+- Makes loop-protection reminder delivery and telemetry settle only when the model request carrying the reminder is accepted, preventing premature clearing or logging. ([#15559](https://github.com/QwenLM/qwen-code/pull/15559)) by @suzhiguo7
+- fix(core): don't treat fd duplication (2>&1) as a file write in shell permission checks ([#15681](https://github.com/QwenLM/qwen-code/pull/15681)) by @Suaroman
+- Sanitizes goal approval text and edit-diff file paths in Web Shell by escaping control and bidi characters so displayed approval content cannot carry hidden controls. ([#16080](https://github.com/QwenLM/qwen-code/pull/16080)) by @yiliang114
+- Shows Managed Session list failures as a localized Retry notice with request details and avoids the empty state until loading succeeds. ([#16082](https://github.com/QwenLM/qwen-code/pull/16082)) by @yiliang114
+- Fixes invalid Javadoc left after the module split so the managed-agent release profile can build documentation again. ([#16099](https://github.com/QwenLM/qwen-code/pull/16099)) by @doudouOUC
+- Moves the Web Shell managed session list failure notice below the Sessions / Archived tabs and prevents its request id from being cut off. ([#16104](https://github.com/QwenLM/qwen-code/pull/16104)) by @yiliang114

+## Daemon Mode
+
+Run Qwen Code as a long-lived service when you want browser, editor, SDK, and automation clients to share agent sessions without each starting a separate process. The daemon provides the built-in Web Shell and an HTTP + SSE API, supports multiple workspaces, and lets clients reconnect to active sessions.
+
+Start it in the foreground and open the Web Shell:
+
+```bash
+qwen serve --open
+```
+
+The default address is `http://127.0.0.1:4170`. To run and manage it in the background instead:
+
+```bash
+qwen daemon start
+qwen daemon status
+qwen daemon logs -f
+qwen daemon stop
+```
+
+By default, the daemon listens on loopback without bearer authentication; any local process that can reach it can use the full API, including code execution. On shared or untrusted hosts, set `QWEN_SERVER_TOKEN` and use `--require-auth`. See the [Daemon guide](./docs/users/qwen-serve.md) for workspaces, authentication, remote access, and the API.
+
 ## Capabilities
 
 If you know Claude Code, you already know Qwen Code — and then some. We've put significant effort into [bringing Qwen Code to feature parity with Claude Code](https://github.com/wenshao/codeagents/blob/main/docs/comparison/qwen-code-improvement-report.md), improving both breadth and reliability across the board.

 Integration regressions proved that model request preparation failures preserve admitted, unsettled inputs through both the ordinary prompt route and the wake driver, and that interrupted channel settlement confirms the original cleanup owner only after its terminal and file-history retirement. A first release failure retained the cleanup fence; passive resident attachment then released the same binding/generation and added one confirmation without a second terminal. A separate Spring/H2 probe passed the bounded-retraction/replay-floor combination: readers remained usable while the snapshot was rebuilding, and old cursors expired again after snapshot coverage caught up.

 一条付出了一个 flake 的 fixture 教训：60 s 的事件轮询/心跳间隔（为强制 live hub 承载投递而设）可把 WebShell 续传压住一个完整轮询周期，而 monitor watch 的空闲窗口必须长过它 —— 空闲超时设 30 s 时，watch 在断流中途把顶在门边的生产者空闲杀掉，用例就吊死在一扇永不再开的门上。watch 以 `idle_timeout_ms` = 180 s 运行。同一轮询也限制续传 observer 追平已提交台账的速度 —— 在重放读取与 relay 停止之间提交的行要晚一个轮询周期才到，所以追平等待设为 120 s，长过两个周期。第二条纪律：monitor producer 绝不自然退出 —— 打过最后一个 mark 后空转，配额停表的 kill 是唯一出路。自然退出会关闭作用域，其 cancel 写入与配额结算赛跑，胜出时把记录翻折成 `stop_requested` 而不是 `max_events`（lane 上实测两次）。

 every committed event, resumes only after JDBC proves events committed
 beyond its cursor, and the client's whole view (the cut frames, then the
 resumed ones) must be one sequence from 1 with no gap and no duplicate,

 Re-measured with the class-wide lease on JDK 21, MySQL 8.4.6 and Linux aarch64: the class passes 9/9 twice (104.4 s and 105.9 s). The R1-1 cell takes 10.8–11.4 s against its recorded 11.4–11.9 s, and every other case stays within its earlier range, so the budget entries above stand. Those runs predate the writer-scoped expiry; with it the class passes 9/9 again (104.8 s, and 107.8 s once it also checks that the leases lapsed), the Harness-kill cases at 11.9–13.4 s. The expiry is asserted rather than inferred from timings: without it each Harness-kill case would still pass, but only after waiting out the full 30 s lease (about 27 s longer per case in a review run).
 
 `HostedMcpStoreFaultGatesIT` is outside this change and still exposed. Three of its cells run the same close preamble (`prepareClose()`: `admitClose`, then `effects` on a live Harness) at a 3 s writer lease, and it has not been measured. Its five Harness kills expire nothing, so a longer lease there has to come with the same dead-writer expiry, or each kill case waits out the lease. The residual is recorded on #15011.

+Decisions:
+
+1. **One class, per-case config.** `HostedMcpRestartFaultGatesIT` adds `fixture2` only for this method's boot; `baseline(session, 2)` waits for both configurations to settle. No new class, no new profile, and the artifact root stays `target/fg12-cases/fg12d/`.
+2. **Two pins, two configurations.** The session's `mcpServers` carries `mcpPin(1)` and `mcpPin("fixture2", 3)`; the Harness installs one configuration per server. Revision 3 distinguishes the second server's fixture events from `fixture`'s revision 1.
+3. **The same-id retry is the claim.** The first 503 and the next 200 carry the same `${configurationId}:release` id; the third 200 carries the other configuration's id. The second configuration is reached only after the first settles.
+
+Mutation witness: `drainConfigurations` iterates `configurations.slice(0, 1)` in a copy of the packaged CLI. The two-server case is red at `settle must complete` because the second configuration stays active; the one-server case stays green, so this case is the one that pins the second configuration. The restored bundle is green.
+
+Budget: the two-server case measures 16.16–16.24 s standalone (two runs) on JDK 21, MySQL 8.4.6 and Linux x86_64; the ten-case class is 81.6 s. It adds 32 s (2×) to the shared healthy sum (11504 → 11536 s), so the `hosted-harness-mysql` fork moves to 11536 s and the Verify step to 203 minutes (12136 s of fork plus wrap); the job ceiling moves to 326 (293 + 33).

+
+Decisions:
+
+1. **The Harness detach route is the gate.** The control-plane lifecycle close is exercised by the R1-1 and two-server cells; this cell calls `POST /session/{id}/detach` directly, which is the production detach that reaches `HostedMcpSession.close()`.
+2. **The unknown is permanent, not a timed window.** The stdio fixture is killed with an `ext://hold` read in flight, so the operation can only settle through a conclusive answer from its original Runtime generation. The detach has no window to race.
+3. **The refusal is one of the documented close answers.** The test accepts 409 `hosted_turn_active` (MCP busy/recovering) and 503 `managed_session_close_failed` / `hosted_mcp_recovery_required`; it rejects 200/204 and asserts no release control and an unchanged unknown record.
+
+Mutation witness: wrap `session.mcp?.close()` in the close path of a packaged CLI copy in `try { … } catch {}`; detach answers 204 and the case is red at the status assertion. The restored bundle is green.
+
+Budget: the case measures 27.4 s worst of two runs (27.4 s and 17.4 s) on JDK 21, MySQL 8.4.6 and Linux x86_64; booked at 55 s (2×). The `hosted-harness-mysql` fork moves to 11591 s, the Verify step to 204 minutes and the job ceiling to 327 (294 + 33).

+2. **两个 pin，两个配置。** Session 的 `mcpServers` 带 `mcpPin(1)` 与 `mcpPin("fixture2", 3)`；Harness 为每个 server 安装一个配置。revision 3 把第二个 server 的 fixture 事件与 `fixture` 的 revision 1 区分开。
+3. **同 id 重试是承重断言。** 第一个 503 与随后的 200 带同一个 `${configurationId}:release` id；第三个 200 带另一个配置的 id。只有第一个配置 settled 之后才会到达第二个配置。
+
+变异见证：在打包 CLI 的副本中让 `drainConfigurations` 只遍历 `configurations.slice(0, 1)`。两个 server 的用例在 `settle must complete` 处变红，因为第二个配置保持 active；一个 server 的用例仍绿，因此是这个用例钉住了第二个配置。还原后的 bundle 复绿。

+
+1. **以 Harness detach 路由为门禁。** 控制面 lifecycle close 已由 R1-1 与两 server 用例覆盖；本格直接调 `POST /session/{id}/detach`，即生产 detach 到达 `HostedMcpSession.close()` 的路径。

 ### ACP prompt turns on the shared round (PR 2a)
 
-PR 2 moves ACP in steps. PR 2a moves the model round of a fresh user prompt: one that is not a retry, a continue or a restore, and not a Goal, channel or goal-proposal approval turn. The round is the loop's own `runModelRound`: one `LlmClient.sendMessageStream` call whose events go to ACP and whose terminal events become stop reasons. ACP keeps its tool step (`runToolCalls`, the next message after tools, the daemon tool-loop guards) and everything around the turn. PR 2b moves the tool batch of these turns onto the scheduler, and PR 2c-1 their stop point onto the client's chain. PRs 2c-2 to 2c-4 then move the other turns, so each of ACP's loop bodies changes once.

+### ACP turns that re-enter a prompt, and channel and Goal-proposal turns (PR 2c-2)
+
+PR 2c-2 puts five more kinds of ACP turn on the shared round, the shared tool batch and the client's stop point. Two are fresh prompts PR 2a left out: channel prompts and Goal-proposal approval turns. Three re-enter a turn the session already has: a retry, a continue of an interrupted turn and the restore of an unanswered `ask_user_question`. Goal turns, cron and background notifications move in PRs 2c-3 and 2c-4.

+| retry                          | ACP strips the failed attempt and puts it back if the retry never sends, as today; the first round is a `Retry` with `historyPromptId`, the attempt's identity, and UserPromptSubmit's verdict from `admitUserPrompt`               |
+| continue                       | ACP strips the interrupted run, or closes the interrupted calls, as today; the first round is a `Retry` with `historyPromptId` and no UserPromptSubmit; a first request that never goes out puts the interrupted run back as it was |
+| restore of `ask_user_question` | ACP asks the question again with its own tool step; the answer is the first round, a `Retry`; later batches run on the shared batch                                                                                                 |
+
+A re-entered turn's first round is a `Retry`, not a `ToolResult`, even when it carries tool results: a `ToolResult` does not start the client's interaction, so the previous prompt's loop-detector counts would carry over and UserPromptSubmit would run on the results. Headless continues an interrupted turn with a `ToolResult` because each of its runs is a new process. A `Retry` gets no system reminders from the client, so ACP adds its plan, arena and output-style reminders to it as today, and the todo reminder ACP takes is the one the client would take.
+
+The restored question keeps ACP's tool step: the shared batch records every result, and a question left unanswered on a timeout must stay unrecorded so a later load can ask it again.
+
+Whether a re-entered turn's first request went out is read from the chat's push count when the round ends, on every exit. A request in history replaces what the turn stripped and carries the restore's notices, even when its response then fails; a request that never went out leaves history as the turn found it, and the notices stay pending.
+
+The core changes of this step: `userTurnRecordedByHost` also covers a `Retry`, whose todo work chain the host started; `promptAdmission` is accepted on a `Retry`; and the new input `historyPromptId`, the history identity a `Retry`'s request carries, spent by its first request.

+重新进入的轮次即使带着工具结果，第一轮也是 `Retry` 而不是 `ToolResult`：`ToolResult` 不会开启 client 的一次交互，上一个 prompt 的循环检测计数会延续下来，UserPromptSubmit 也会在这些结果上运行。headless 用 `ToolResult` 继续被打断的轮次，是因为它每次运行都是一个新进程。client 不给 `Retry` 加系统提醒，所以 ACP 和现在一样为它加上 plan、arena 和 output-style 提醒；ACP 取走的 todo 提醒就是 client 会取的那一条。
+
+被恢复的问题保留 ACP 的工具步骤：共享工具批会记录每一个结果，而因超时没有回答的问题必须保持未记录，之后加载时才能再次提问。
+
+重新进入的轮次的第一条请求是否已经发出，在模型轮结束时按 chat 的推送计数判断，每条退出路径都一样。已进入历史的请求替换轮次剥离的内容，并带上 restore 的提醒，即使随后响应失败也是如此；一直没有发出的请求让历史保持轮次开始时的样子，提醒保持待发。
+
+这一步对 core 的改动：`userTurnRecordedByHost` 也覆盖 `Retry`，表示宿主已经启动了它的 todo 工作链；`Retry` 也接受 `promptAdmission`；新增输入 `historyPromptId`，即 `Retry` 的请求在历史中带的标识，由第一条请求使用。

 Spring resolves `qwen.managed-agent.runtime-broker.state-directory` from many places: the variable the server's `application.yml` maps, `QWEN_MANAGED_AGENT_RUNTIME_STATE_DIRECTORY`; every configuration file in Spring's default locations and the launcher's `SPRING_CONFIG_ADDITIONAL_LOCATION`; the files an import or a profile brings in; `SPRING_APPLICATION_JSON`; system properties; command-line arguments; and every relaxed spelling of the property. Earlier rounds of this command read that list itself and refused on what it recognized, and each round found a source it missed. Its configuration resolution has no closed list, so the command no longer reads it.
 
-Instead, `check` and `backup` ask the server. The server jar has a main class, `ResolvedConfiguration`, that prepares the environment the way `SpringApplication` does before it creates a context: the arguments, the process environment and every environment post-processor on the class path, which load the configuration files, imports and profiles. It then binds the server's properties and prints the state directory, made absolute in the working directory as the server does, where it came from, the auth mode and the trusted actor header, on one line after a fixed prefix. It starts no context, logs nothing and opens no connection.

-The command runs it through `systemd-run` as the control-plane unit runs the server: the unit's account, working directory, environment files and `Environment=` assignments, the `java` on the unit's `PATH`, and the launcher's one default, `config/application.yml` when `SPRING_CONFIG_ADDITIONAL_LOCATION` is unset or empty. It runs this release's jar, copied where the service account can read it wherever the archive was extracted, through `PropertiesLauncher` with `loader.main`, so an older jar without the class fails rather than starting a server. `verify`, which runs after `install`, uses the installed jar and reads the auth mode from the same output. The admin launcher runs the same class as `resolved-configuration`, for the manual procedure on other layouts.

The admin launcher runs the same class as `resolved-configuration`, for the manual procedure on other layouts.
 
 Two cases stay with the operator. The jar can fail to resolve the configuration, as when an import names a missing file, which the server would refuse too. And `systemctl show` prints `ExecStart` arguments joined by spaces, unquoted, so the command cannot pass on arguments the unit gives the launcher. In either case `backup` refuses until `--runtime-state <directory>` names the directory, or `--runtime-state none` declares a deployment that keeps no Runtime state. A backup without the Runtime state the database refers to cannot be restored consistently, so a backup that silently left it out would be worse than a refusal. When the configuration names no directory, as on a deployment without the tool path, `backup` archives none and prints that.
 
+### Listener URLs
+
+`start` waits for the Harness's port and for the control plane's health endpoint, and `verify` probes that endpoint and reads the API. Each address can be set where `server.env` does not show it: `server.port` in `config/application.yml`, a relaxed `SERVER_ADDRESS`, an argument, or a `management.server.port` that moves the actuator to a listener of its own. Read from `server.env` alone, `start` would wait out `--timeout` on a port nothing serves. So both phases take the URLs from the same `ResolvedConfiguration` output:
+
+- **Control plane:** the address `server.address` binds, the port `server.port` binds and `https` when `server.ssl` is enabled. A wildcard bind is reached on the loopback interface of its family, and any other address as bound.
+- **Health endpoint:** Spring Boot's rules for the management port (`ManagementPortType`). Unset or equal to the server's port, it shares the server's listener. A negative one turns the HTTP endpoints off. Any other one opens a listener on `management.server.address`, which binds every interface when unset, under `management.server.base-path`, keeping the server's TLS unless `management.server.ssl` replaces it. `management.endpoints.web.base-path` and the `health` path mapping apply either way, and a blank mapping keeps the name `health`, as Spring Boot ignores it.
+- **Harness:** `qwen.managed-agent.harness.base-url`, the URL the control plane dials.
+
+A port of 0, picked at start, or a negative one leaves no URL to wait on, so both phases refuse until `--server-url` names one. They refuse as well when a URL cannot name the listener, as for a link-local IPv6 address, which keeps its zone, or a `--server-url` that is not a URL, rather than wait out `--timeout` on probes that cannot be sent. `--server-url` still names the control plane, for example behind a proxy, and the health endpoint is then `<url>/actuator/health`; `verify`, which does not reach the Harness, then resolves the configuration only for `--tenant`. When the configuration does not resolve, in the two cases above, the two phases use the URLs `server.env` names, as the command did before, and print a line that says which: a wrong guess then costs a `--timeout`, where refusing would stop an upgrade that the guess serves.

 有两种情况留给运维处理。一是 jar 无法解析配置，例如 import 指向的文件不存在，这时服务端同样会拒绝启动。二是 `systemctl show` 打印 `ExecStart` 参数时用空格拼接且不加引号，命令无法准确地转交 unit 传给 launcher 的参数。这两种情况下，`backup` 都会拒绝执行，直到 `--runtime-state <目录>` 指明目录，或用 `--runtime-state none` 表示部署不保存 Runtime 状态。缺少数据库所引用的 Runtime 状态的备份无法一致地恢复，因此悄悄漏掉状态的备份比拒绝更糟。配置中没有指定目录时（例如未开启工具路径的部署），`backup` 不归档 Runtime 状态，并打印说明。
 
+### 监听 URL
+
+`start` 等待 Harness 的端口和控制面的健康端点，`verify` 探测该端点并读取 API。这些地址都可能设置在 `server.env` 看不到的地方：`config/application.yml` 中的 `server.port`、relaxed 形式的 `SERVER_ADDRESS`、命令行参数，或者把 actuator 移到独立监听上的 `management.server.port`。只从 `server.env` 推算时，`start` 会在一个无人监听的端口上等满 `--timeout`。因此两个阶段都从同一份 `ResolvedConfiguration` 输出中取得 URL：
+
+- **控制面：** `server.address` 绑定的地址、`server.port` 绑定的端口；启用 `server.ssl` 时用 `https`。通配地址经其地址族的回环接口访问，其他地址按绑定的地址访问。
+- **健康端点：** 遵循 Spring Boot 关于 management 端口的规则（`ManagementPortType`）。未设置或与服务端端口相同时，它与服务端共用监听；为负数时关闭 HTTP 端点；其他值则在 `management.server.address` 上打开独立监听（未设置时绑定所有接口），位于 `management.server.base-path` 之下，并沿用服务端的 TLS，除非 `management.server.ssl` 替换它。两种情况下都应用 `management.endpoints.web.base-path` 和 `health` 的路径映射；路径映射为空白时 Spring Boot 会忽略它，仍使用名称 `health`。
+- **Harness：** `qwen.managed-agent.harness.base-url`，即控制面访问它所用的 URL。
+
+端口为 0（启动时选取）或负数时没有可等待的 URL，因此两个阶段都会拒绝执行，直到 `--server-url` 指定一个。URL 无法表示该监听时（例如保留了 zone 的 IPv6 链路本地地址），或者 `--server-url` 不是 URL 时，两个阶段同样拒绝执行，而不是在根本发不出去的探测上等满 `--timeout`。`--server-url` 仍可指定控制面的地址，例如位于代理之后，此时健康端点为 `<url>/actuator/health`；`verify` 不访问 Harness，这时只为 `--tenant` 解析配置。无法解析配置时（即上文的两种情况），两个阶段与以前一样使用 `server.env` 中给出的 URL，并打印一行说明用了哪些：猜错的代价是等满一次 `--timeout`，而拒绝执行会挡住猜对时本可以完成的升级。

+# Mod prompt submission
+
+[English](2026-10-30-mod-prompt-submit.md) | [简体中文](2026-10-30-mod-prompt-submit.zh-CN.md)
+
+Status: proposed. This stage follows the turn events in #15443 and is tracked in #13749. It follows the Claude Code 2.1.310 plugin API declarations of `prompt.submit` and `$.prompt.submit`.
+
+## Problem and current behavior
+
+Mods written for Claude Code act on the prompts a person sends:
+
+- A guard drops a prompt that holds a credential, with `{ drop: reason }`.
+- A Mod rewrites a prompt, for example to expand a shorthand, with `next({ ...e, text })`.
+- A Mod attaches context the model reads beside the prompt and the person never sees, with `next({ ...e, context: [...] })`.
+- A Mod sends a prompt of its own once the session is idle, with `$.prompt.submit`.
+
+Qwen Code skips `prompt.submit` hooks at load and reports `Hooks for unsupported events will not run: prompt.submit`. A guard written there silently does not run.
+
+## Goals and non-goals
+
+Goals, in four pull requests:
+
+1. Core and headless runs: the event, its rules and its context. This document lands with it.
+2. The Ink terminal.
+3. The OpenTUI terminal.
+4. `$.prompt.submit`.
+
+Non-goals:
+
+- Slash commands, which Claude Code raises with `command`. They come with a later step on command rows.
+- Prompts the person did not type: background notifications, scheduled prompts, teammate messages, goal continuations and the continuation of an interrupted turn. Claude Code marks some of these with `isMeta`.
+- Prompts typed while a turn runs that steer it at a model boundary.
+- `attachments` and `$.prompt.media`.
+
+## Proposed changes
+
+### 1. When it fires
+
+`prompt.submit` fires for each prompt a person submits, after the host has its text and before anything reads it: before UserPromptSubmit, before `@` references are read and before the user message is recorded or shown. Only a host that raises the event loads its hooks; any other host skips them at startup with the usual line, so a guard is never silently bypassed. Step 1 raises it in headless runs, for the `-p` prompt and each stream-json user message.
+
+### 2. Input
+
+| Field     | Value                                                                                          |
+| --------- | ---------------------------------------------------------------------------------------------- |
+| `text`    | the prompt as submitted, with pasted text expanded; for a stream-json message, its text blocks |
+| `context` | absent as the host raises it                                                                   |
+| `wait`    | `false`                                                                                        |
+| `origin`  | `{ kind: 'sdk' }` in headless runs; `{ kind: 'composer' }` in the terminals                    |
+| `turnId`  | absent until a terminal raises the event for a prompt typed during a turn                      |
+
+A hook passes `text` and `context` on to `next`; `origin`, `wait` and `turnId` are pinned. `context` is a list of texts.
+
+### 3. What enters
+
+The prompt that enters is the one that arrives beneath the hooks, as in Claude Code: the worker records the `text` and `context` that reach the bottom of the chain. `next(e)` resolves to them with the origin. What a hook answers after its `next` resolved changes nothing, and only a drop there is checked.
+
+The chain settles one of three ways:
+
+- the prompt arrived beneath the hooks: it enters with its text and context;
+- a hook answered `{ drop: reason }`: the prompt is dropped by a hook;
+- the chain settled without reaching the bottom, because a hook answered `{ text }` without `next`: the prompt is not submitted, as Claude Code's `a hook answered without passing the prompt on`.
+
+A hook that answers a drop after calling `next` fails, as in Claude Code: its `.catch` is asked, or it is skipped and its last `next` stands. A hook that fails or times out is skipped, and a failed worker lets the prompt through unchanged, so a broken plugin never blocks a prompt.
+
+### 4. Rewrite and context
+
+A rewritten text replaces the prompt everywhere the host keeps it: the text sent to the model, the text `@` processing reads, the `turn.start` text, the transcript record and its display text. A stream-json message that also has blocks other than text reaches the model as text with those blocks serialized; the hooks hear only its text blocks, and a rewrite replaces them, with the other blocks after it, in the model's text and in the transcript alike, as without a rewrite.
+
+The context joins UserPromptSubmit's `additionalContext` in the hidden block core already appends after the prompt, ahead of it, escaped the same way. The client takes it as a new send option, `promptContext`, which only the prompt's own UserQuery spends. The transcript records the block as hook context, so resume hides it and compaction keeps it the way it keeps UserPromptSubmit's.
+
+### 5. Drop
+
+A drop stops the prompt before UserPromptSubmit and before any model request, and starts no turn. The reason is one line, kept to its first 4,096 characters with an ellipsis after, as Claude Code keeps it. Headless runs end with the error result `Prompt dropped by a hook: <reason>`, or `Prompt not submitted: a hook answered without passing the prompt on`, and exit code 1. A stream-json session goes on to its next message.
+
+### 6. Limits
+
+A prompt longer than half a Mod payload (128 KiB as JSON) reaches no hook, and the line `prompt.submit hook skipped: the prompt is too long for a Mod payload` appears where transcript logs do. Claude Code passes it whole. A rewrite or context that makes a hook's answer larger than a Mod payload fails that hook.
+
+## Design decisions
+
+- **The host raises the event.** Each host already holds the submitted text before it expands or records it. Raising the event there keeps the rewrite ahead of every use of the text without changing core's send.
+- **UserPromptSubmit runs after the Mod hooks, in core.** Claude Code runs both in one admission and lets a settings hook's block beneath turn `next(e)` into `{ drop }`. Here the bottom of the chain does not wait for UserPromptSubmit, which runs later in the send and can take as long as its commands. A Mod that must know whether UserPromptSubmit blocked a prompt can read `turn.start`, which only an admitted prompt raises.
+- **Hosts opt in.** The load request says whether the host raises `prompt.submit`, as it names the sites it draws for `ui.render`, so each step enables only the host it adds.
+- **The context shares the hook context block.** It reaches the model, the transcript and resume the way UserPromptSubmit's context does, so no new record kind is needed. A context the conversation already holds word for word is not sent again, as for UserPromptSubmit. Each Mod context and UserPromptSubmit's count on their own, so a Mod context that changes every turn does not make an unchanged UserPromptSubmit context repeat.
+
+## Differences from Claude Code
+
+These go into the user guide:
+
+- Until steps 2 and 3, only headless runs raise `prompt.submit`.
+- Slash commands and prompts the person did not type raise none, so `command` and `isMeta` never appear.
+- `attachments` never appears, and `$.prompt.media` does not exist.
+- A UserPromptSubmit block does not turn `next(e)` into `{ drop }`, and `next(e)` resolves before the turn starts.
+- A context the conversation already holds word for word is not sent again, each Mod context and UserPromptSubmit's on its own.
+- A prompt longer than 128 KiB as JSON reaches no hook.
+- A headless drop is an error result with exit code 1.
+
+## Validation and acceptance
+
+- Real QuickJS worker tests:
+  - which plugins hear the event, and a host that raises none skipping its hooks;
+  - the prompt and context that arrive beneath the hooks, and an answer after `next` that changes nothing;
+  - a hook's drop, and a hook that answers without `next`;
+  - a downstream drop's reason survives a post-next text answer across plugins, within one plugin, and during recovery; a caught late drop does not replace a later local continuation's outcome or mark a host continuation as called;
+  - a drop after `next`, a changed `origin` or `wait`, a context that is not a list, a wrong answer and a throw, each skipped;
+  - a `.catch` that drops for a failed guard.
+- Mod session tests: no hooks, the origin, a rewrite with context, a drop's one line and its 4,096 characters, a failed worker, a cancelled prompt, and a prompt too long for a payload.
+- Client test: the Mods' context ahead of UserPromptSubmit's, escaped, with and without UserPromptSubmit hooks, and only for a new prompt.
+- Headless tests: the rewritten prompt and its context reaching the send and `turn.start`, a drop in JSON and text, and no event for a slash command or a notification.
+- The built CLI against a fixture server in headless JSON, text and stream-json: a rewrite that the model request and the transcript both hold, context in the hidden block, a drop, and a guard whose `.catch` drops.
+
+## Risks and open questions
+
+- A slow hook delays the prompt by up to its budget, 10 seconds a hook.
+- Masking a slash command's arguments needs `command.run` today; `prompt.submit` with `command` comes later.

+# Mod 提示提交
+
+[English](2026-10-30-mod-prompt-submit.md) | [简体中文](2026-10-30-mod-prompt-submit.zh-CN.md)
+
+状态：提议中。本阶段接在 #15443 的回合事件之后，由 #13749 跟踪。依据是 Claude Code 2.1.310 插件 API 对 `prompt.submit` 和 `$.prompt.submit` 的声明。
+
+## 问题与现状
+
+为 Claude Code 写的 Mod 会处理用户发出的提示：
+
+- 守卫用 `{ drop: reason }` 拦下含有凭据的提示。
+- Mod 用 `next({ ...e, text })` 改写提示，例如展开缩写。
+- Mod 用 `next({ ...e, context: [...] })` 附上模型能读到、用户看不到的上下文。
+- Mod 用 `$.prompt.submit` 在会话空闲后发出自己的提示。
+
+Qwen Code 在加载时跳过 `prompt.submit` hook，并提示 `Hooks for unsupported events will not run: prompt.submit`。写在这里的守卫不会运行。
+
+## 目标与非目标
+
+目标，分四个 PR：
+
+1. core 和 headless：事件本身、规则和上下文。本文随它合入。
+2. Ink 终端。
+3. OpenTUI 终端。
+4. `$.prompt.submit`。
+
+非目标：
+
+- 斜杠命令。Claude Code 对它们带 `command` 触发，留到后续处理命令行的步骤。
+- 不是用户输入的提示：后台通知、定时提示、队友消息、goal 续跑、中断回合的续跑。Claude Code 对其中一部分标 `isMeta`。
+- 回合进行中输入、在模型边界插入当前回合的提示。
+- `attachments` 和 `$.prompt.media`。
+
+## 方案
+
+### 1. 触发时机
+
+用户每提交一个提示，在宿主拿到文本之后、任何地方读取它之前触发 `prompt.submit`：在 UserPromptSubmit 之前，在读取 `@` 引用之前，在记录或显示用户消息之前。只有会触发该事件的宿主才加载它的 hook；其他宿主在启动时照常跳过并给出提示，守卫不会被悄悄绕过。第 1 步在 headless 运行中触发：`-p` 的提示和 stream-json 的每条用户消息。
+
+### 2. 输入
+
+| 字段      | 值                                                           |
+| --------- | ------------------------------------------------------------ |
+| `text`    | 提交的提示，粘贴内容已展开；stream-json 消息只取其文本块     |
+| `context` | 宿主触发时不带                                               |
+| `wait`    | `false`                                                      |
+| `origin`  | headless 为 `{ kind: 'sdk' }`；终端为 `{ kind: 'composer' }` |
+| `turnId`  | 不带，直到终端为回合进行中输入的提示触发该事件               |
+
+hook 可以把改过的 `text` 和 `context` 传给 `next`；`origin`、`wait`、`turnId` 不可改。`context` 是文本列表。
+
+### 3. 最终提交什么
+
+和 Claude Code 一样，提交的是穿过所有 hook 到达链底的提示：worker 记录到达链底的 `text` 和 `context`。`next(e)` 解析为它们，外加 origin。hook 在 `next` 返回之后再给出的答复不起作用，这时只检查它是不是 drop。
+
+链的结果有三种：
+
+- 提示到达链底：带着它的文本和上下文提交；
+- 某个 hook 答复 `{ drop: reason }`：提示被 hook 丢弃；
+- 链没有到达链底就结束了，因为某个 hook 没调 `next` 就答复了 `{ text }`：提示没有提交，对应 Claude Code 的 `a hook answered without passing the prompt on`。
+
+和 Claude Code 一样，调过 `next` 之后再答复 drop 的 hook 算失败：先问它的 `.catch`，否则跳过它，保留它最后一次 `next` 的结果。失败或超时的 hook 被跳过；worker 出错时提示原样通过。坏掉的插件不会拦住提示。
+
+### 4. 改写与上下文
+
+改写后的文本在宿主保存提示的每一处都替换掉原文：发给模型的文本、`@` 处理读取的文本、`turn.start` 的文本、transcript 记录及其显示文本。stream-json 消息若还带有非文本块，这些块会序列化后随文本发给模型；hook 只听到其中的文本块，改写替换的也是文本块，其他块接在改写后的文本之后；发给模型的文本和 transcript 都是这样，与没有改写时一致。
+
+上下文并入 core 已有的隐藏块，即追加在提示之后、存放 UserPromptSubmit `additionalContext` 的那一块，排在后者之前，转义方式相同。client 通过新的发送选项 `promptContext` 接收它，只有该提示自己的 UserQuery 会用掉它。transcript 把这一块记作 hook 上下文，因此恢复会话时它仍然隐藏，压缩时也和 UserPromptSubmit 的上下文一样保留。
+
+### 5. 丢弃
+
+drop 在 UserPromptSubmit 和任何模型请求之前拦下提示，不开始回合。原因只保留一行，最多 4,096 个字符，超出部分以省略号结尾，与 Claude Code 相同。headless 运行以错误结果 `Prompt dropped by a hook: <reason>`（或 `Prompt not submitted: a hook answered without passing the prompt on`）结束，退出码为 1。stream-json 会话继续处理下一条消息。
+
+### 6. 限制
+
+超过 Mod 负载一半（JSON 128 KiB）的提示不经过任何 hook，并在 transcript 日志出现的位置给出 `prompt.submit hook skipped: the prompt is too long for a Mod payload`。Claude Code 会完整传递。改写或上下文让 hook 的答复超过 Mod 负载时，该 hook 算失败。
+
+## 设计决策
+
+- **由宿主触发事件。** 每个宿主在展开或记录提示之前就已拿到提交的文本。在这里触发，改写就能先于文本的每一次使用，且不必改 core 的发送流程。
+- **UserPromptSubmit 在 Mod hook 之后、在 core 里运行。** Claude Code 把两者放在同一次准入里，下层设置 hook 的拦截会让 `next(e)` 变成 `{ drop }`。这里链底不等 UserPromptSubmit：它在发送流程更靠后的位置运行，耗时取决于它的命令。需要知道 UserPromptSubmit 是否拦下提示的 Mod 可以看 `turn.start`，只有获准的提示才会触发它。
+- **宿主自行声明。** 加载请求说明宿主是否触发 `prompt.submit`，就像它为 `ui.render` 列出绘制的位置一样。每一步只为它新增的宿主开启。
+- **上下文共用 hook 上下文块。** 它到达模型、进入 transcript、在恢复时的处理都和 UserPromptSubmit 的上下文一致，不需要新的记录类型。会话里已有一字不差的同一上下文时不再发送，与 UserPromptSubmit 相同。每条 Mod 上下文和 UserPromptSubmit 的上下文分别判断，所以每轮都变的 Mod 上下文不会让没变的 UserPromptSubmit 上下文重复发送。
+
+## 与 Claude Code 的差异
+
+以下内容写进用户指南：
+
+- 第 2、3 步之前，只有 headless 运行触发 `prompt.submit`。
+- 斜杠命令和不是用户输入的提示不触发它，所以不会出现 `command` 和 `isMeta`。
+- 不会出现 `attachments`，也没有 `$.prompt.media`。
+- UserPromptSubmit 的拦截不会让 `next(e)` 变成 `{ drop }`；`next(e)` 在回合开始之前就返回。
+- 会话里已有一字不差的同一上下文时不再发送，每条 Mod 上下文和 UserPromptSubmit 的上下文分别判断。
+- 超过 JSON 128 KiB 的提示不经过任何 hook。
+- headless 的 drop 是错误结果，退出码为 1。
+
+## 验证与验收
+
+- 真实 QuickJS worker 测试：
+  - 哪些插件收到该事件，以及不触发它的宿主跳过它的 hook；
+  - 到达链底的提示和上下文，以及 `next` 之后的答复不起作用；
+  - hook 的 drop，以及不调 `next` 就答复的 hook；
+  - 跨插件、同一插件内和恢复路径中，`next` 返回后的文本答复都保留下层 drop 的原因；被捕获的迟到 drop 不覆盖后续本地 continuation 的结果，也不把宿主 continuation 标记为已调用；

+# Hosted A6 — block on uncertain producer evidence
+
+Status: implemented. Slice of Issue #14481 (G3 Step 3 recovery matrix), row **A6**
+("MCP/Hook/child uncertainty"). Per the parent design's §9.1, A6 stays focused or
+integration evidence: this slice adds focused behavioural evidence, guards every
+recovery writer against uncertain child evidence, and keeps a bounded cancel
+escape for the resulting block. No new CI arm, no new continuation support, no
+change to the Hook/MCP refusal policy itself.
+
+Parent: [G3 Step 3 recovery](2026-10-09-hosted-g3-step3-recovery.md).
+中文版：[2026-10-31-hosted-a6-uncertainty-evidence.zh-CN.md](2026-10-31-hosted-a6-uncertainty-evidence.zh-CN.md).
+
+## Problem
+
+A6 requires three observations: missing or unknown producer evidence blocks; no
+external call is recreated; no Workspace lease is silently released. An
+investigation of main `35daec35ea` (two parallel code surveys, key claims
+re-verified by hand) shows the second and third clauses are already thickly
+guarded and tested, while the first clause has three concrete evidence gaps:
+
+- **G1 — the Hook/MCP saved-batch refusal arm has zero tests.**
+  `resumeSavedNativeBatch` refuses a non-commandStep plan owned by a Hook/MCP
+  session with `HostedToolRecoveryRequiredError('Unsupported saved batch owner.')`
+  (`hosted-workspace-tool-turn.ts:3508-3517`). The string appears nowhere in any
+  test; the approval-continuation fixtures never construct a hooks/mcp resume.
+  Deleting the clause is predicted to keep every suite green.
+- **G2 — the extensions-enabled entry combination is unpinned.** The takeover
+  continuation entry (`hosted-harness-session.ts:7124-7129`) admits sessions with
+  `session.extensions?.enabled` even when `session.hooks || session.mcp`; the only
+  backstop for a non-commandStep plan is G1's untested clause. (Resolution scope:
+  this slice pins the tool-turn backstop in both gate directions; the entry's
+  `extensions?.enabled` clause itself is a route-level surface recorded as a
+  follow-up below — a focused fixture cannot reach it without a full
+  hooks-session takeover, and a row that cannot fail is worse than no row.)
+- **G3 — an unavailable child ledger is answered as proven absence.**
+  `fillParkedRoundAgentGaps` folds `gapText` for a stranded call when
+  `children === undefined || admitted === undefined`
+  (`hosted-runtime-recovery.ts:1505-1517`). The two arms are not the same evidence:
+  with the ledger present, no `child_run` record is positive never-started proof
+  (`admitLaunch` commits the record before `dispatchStarted`,
+  `hosted-child-agent-session.ts:1383-1415`); with the ledger absent, nothing is
+  known — yet the fold asserts "the call never ran"
+  (`HOSTED_AGENT_CALL_NOT_REACHED_TEXT`, `hosted-workspace-tool-turn.ts:1660-1661`).
+  The ledger family is `agent` AND `workflow`: the module's other readers already
+  treat the two names as one (`hosted-runtime-recovery.ts:790, 1913`,
+  `JOURNAL_ONLY_ANSWERABLE_TOOLS`), and workflow admission requires the child
+  funnel. `session.childAgents` is rebuilt deterministically from persisted
+  session configuration at load (`hosted-harness-session.ts:6265-6307`), so the
+  absent arm is unreachable for a stable configuration that never had the agent
+  tool — but it is reachable across child-lane configuration/version drift
+  between the crashed generation and the recovering one (reproducible at route
+  level via `suppressChildAgents` on a version-0 lane), exactly when an admitted
+  child may still be running. No test distinguishes the two arms.
+
+## Verified code facts (main 35daec35ea)
+
+- Producer evidence is durable and pre-dispatch for all three producers: Hook
+  `hook_execution` records and MCP `mcp_operation` records run
+  `intent → dispatch_started → settled | outcome_unknown | not_started_proven`,
+  with `dispatch_started` committed before the physical dispatch
+  (`hosted-hook-session.ts:1187-1193, 1362-1378`;
+  `hosted-mcp-session.ts:865-882`); child runs commit `child_run` before dispatch.
+- Uncertain Hook/MCP results are lookup-only (`hook-status` / status polling);
+  non-settled lookups commit `recovery_blocked / outcome_unknown` and throw the
+  family recovery error. No path recreating an uncertain external call was found
+  (dispatch only from `intent`; `reconcileEffects` cancels intents, never
+  redispatches; child admission is evidence-idempotent).
+- Clause 3 is guarded by persistent evidence, not tool lists: Java release
+  refuses while any execution row is non-terminal
+  (`JdbcToolExecutionRepository.hasActiveByRuntimeSession`), descendant half
+  evidence blocks retirement (`ManagedRuntimeRetentionGuard.childRunUnsettled`),
+  and the CLI fast-settle path requires a non-empty all-settled list. Tested
+  witnesses include `hosted-mcp-session.test.ts:846, 1762` (unknown outcome keeps
+  the owner / blocks replacement), `hosted-hook-session.test.ts:892` (unknown
+  result keeps the mount), and `HostedMonitorRunFaultGatesIT` (uncertain worker →
+  `runtime_session_held`, binding stays READY).
+
+## Changes
+
+- **G1/G2 (tests only).** A five-row owner-gate matrix in
+  `hosted-approval-continuation.test.ts`: a non-commandStep saved plan under a
+  hooks-owned and under an mcp-owned turn is refused with the
+  `'Unsupported saved batch owner.'` cause; a hooks owner with
+  `extensionConfig` and no commandStep is refused by the same first arm; a
+  commandStep plan whose `configRevision` no longer matches the turn's
+  `extensionConfig.revision` is refused by the gate's second arm; and a
+  matching-revision commandStep plan under a hooks owner proceeds PAST the gate
+  (its rejection is the wrapped transport failure, never the owner cause) —
+  pinning the over-blocking direction that keeps the A3 commandStep follow-up
+  working. The gap is demonstrated first: deleting the owner-gate clause keeps
+  the pre-change suites green.
+- **G3 (recovery writers + a bounded cancel escape).** On a live signal, an
+  owed fold for a ledger-family call (`agent` or `workflow`) with
+  `children === undefined` refuses in `fillParkedRoundAgentGaps`,
+  `fillParkedRoundCommandGaps`, and the hosted resumed-turn answer. The common
+  `HostedChildLedgerRecoveryRequiredError` subtype marks exactly this evidence
+  block for the route. Already-journaled gaps stay silent, non-family gaps keep
+  their existing answers, and a present ledger's missing record remains positive
+  never-started proof. Pre-aborted terminating fills and the `'all'` settlement
+  write `HOSTED_CHILD_LEDGER_UNKNOWN_TEXT` with `executionStatus: 'unknown'`,
+  never a fabricated never-ran or cancelled outcome. Route witnesses build the
+  drift into the load (`suppressChildAgents` on the orphan parked shape):
+  continue blocks retriably with no fabricated fold, then managed-runtime cancel
+  settles that same blocked Turn, writes the cancelled terminal, clears the
+  recovery block, and lets the public cancel replay answer 204. A different
+  recovery block still refuses cancel with 409 `turn_blocked`.
+
+## Design decisions
+
+- **Block, not fold, for an unavailable ledger.** A6's first clause is about
+  evidence semantics: "unknown" must not be laundered into "proven absent". The
+  fold is durable and answers the model; a wrong never-ran claim can strand a
+  live child's effect with no owed response.
+- **The ledger family, not just `agent`.** `workflow` launches ride the same
+  child-run ledger (the module's other readers treat the two names as one
+  family), so the same unavailable-evidence block covers both. Other stranded
+  calls keep the existing gap answer, so the guard cannot regress sessions
+  that legitimately have no child funnel.
+- **Abort exemption for the terminating routes.** Cancel and the interrupted
+  settle funnel deliberately pre-abort the fill ("settles at once … instead of
+  holding the cancel hostage"); the guard exempts an already-aborted signal so
+  those paths always terminate. Their ledger-less family folds say the outcome
+  is unknown and retain the record; they never claim the call never ran or was
+  observed cancelled.
+- **A bounded terminal escape after the block.** Only the A6 subtype arms
+  `recoveryCancelPromptId`; only that Turn's managed-runtime cancel bypasses
+  the blocked refusal. The failed continue's admission is removed so it cannot
+  replay as a cancellation, and the block lifts only after a cancelled terminal
+  is durable. Other recovery blocks keep their 409 refusal and lease behavior.
+- **No packaged arm, no continuation support.** §9.1 classifies A6 as focused or
+  integration evidence, and native continuation refuses Hook/MCP sessions by
+  design (the commandStep follow-up is A3's other half). Packaging a Hook/MCP
+  crash arm would need new e2e fixtures and is a separate slice.
+- **Lease-side observations stay out of scope.** Hook/MCP-profile Turns do not
+  enter the HOSTED_CLEANUP debt protocol (`!hooks && !mcp` gates), so the C3
+  scanner does not re-drive their leases; that is a cleanup-coverage question
+  (a stuck lease is not a silent release), recorded here as an adjacent
+  observation for a future C3 slice, not an A6 defect.
+
+## Files affected
+
+- `packages/cli/src/serve/hosted-runtime-recovery.ts` (G3 writer guards and the
+  A6 error subtype)
+- `packages/cli/src/serve/hosted-harness-session.ts` (the bounded cancel escape)
+- `packages/cli/src/serve/hosted-child-wait-recovery.test.ts` (G3 fill-level cases)
+- `packages/cli/src/serve/hosted-background-launch-recovery.test.ts` (the
+  journal-only workflow/ledger refusal)
+- `packages/cli/src/serve/hosted-harness-session.test.ts` (G3 route-level cases)
+- `packages/cli/src/serve/hosted-approval-continuation.test.ts` (G1/G2 matrix)
+- this design doc (both languages); the parent §9.1 status note is updated when
+  the focused evidence lands.
+
+## Acceptance criteria
+
+- G1/G2: the owner-gate deletion survives the pre-change suites (demonstrated
+  gap) and reds the refusal rows afterwards; removing `!plan.commandStep &&`
+  reds exactly the matching-revision acceptance row; removing the second
+  (revision) arm reds exactly the stale-revision row. The harness entry's
+  `extensions?.enabled` clause is NOT claimed as pinned (follow-up below).
+- G3: the absent-ledger counterexample folds "never ran" before the guard and
+  throws with no fold written after it, for both `agent` and `workflow`; the
+  ledger-present/no-record arm still folds the honest answer; a non-family gap
+  call is unchanged; a journaled gap replays silently. Pre-aborted fills and the
+  `'all'` settlement write the unknown outcome; the settlement's own answering
+  pass pins `executionStatus: 'unknown'`. At route level under built-in drift:
+  continue blocks retriably (409) with no fabricated fold, then cancel settles
+  that same Turn and clears the block; an unrelated recovery block still
+  refuses cancel. Each new guard or escape clause has a delete-control that
+  reds its named case.
+- Focused suites green under a sanitized environment (agent-session env vars
+  stripped), typecheck/ESLint/Prettier green; production changes stay limited to
+  the recovery writers and the bounded cancel escape.
+
+## Open questions
+
+- Pinning the harness takeover entry's `session.extensions?.enabled` clause at
+  route level (needs a hooks-session takeover fixture with a durable v3
+  continuation; the tool-turn backstop it gates is already pinned both ways).
+- Whether a later slice packages an A6 fault arm once Hook/MCP e2e fixtures
+  exist (out of scope here).
+- Whether Hook/MCP-profile Turn leases should join the cleanup-debt protocol
+  (adjacent C3-scope observation above).
+
+## R2 review round (4 Suggestions — all fixed)
+
+- **Sibling writers (R2-1)**: the same never-ran fabrication survived at two
+  sibling writers on the recovery paths. `answerAbandonedTurnCalls` (hosted
+  mode, the continue route's resumed-turn answer) now refuses a ledger-less
+  family call — its caller's family catch maps the refusal to the retriable
+  block; the terminating `'all'` settlement keeps folding but on the honest
+  wording (below). `fillParkedRoundCommandGaps` (which never reads the
+  ledger) refuses the same shape on a live signal; its continue-route caller
+  passes the live signal, the cancel and settle callers pre-abort.
+- **Honest exempted wording (R2-3)**: the exempted (pre-aborted) folds and the
+  `'all'` settlement answer a ledger-less family call with a new dedicated
+  `HOSTED_CHILD_LEDGER_UNKNOWN_TEXT` — "outcome is unknown … record is
+  retained", `executionStatus: 'unknown'` — never "never ran" and never
+  "cancelled". The funnels still terminate without throwing.
+- **One family fact (R2-4)**: `CHILD_LEDGER_TOOL_NAMES = new Set(['agent',
+'workflow'])` lives in `hosted-workspace-tool-turn.ts` beside the answer
+  constants; all six former inline two-name literals (four in recovery, two
+  in the tool-turn mount-validation arms) read `.has(name)` from it. Not
+  `JOURNAL_ONLY_ANSWERABLE_TOOLS` — that set also holds the team names whose
+  gap answer is their own funnel.
+- **The extensions row (R2-2)**: the owner-gate matrix gained the row its
+  comment claimed — a Hook owner with `extensionConfig` and NO `commandStep`
+  is refused by the first arm; smuggling `&& !this.extensionConfig` into the
+  gate reds exactly that row.
+
+R2 delete-controls (quiet tree, failure-list adjudication): the family
+constant hollowed to `agent`-only at the fill guard; the resumed-answer
+refusal removed; the `'all'` settlement's unknown wording reverted; the
+command-gaps refusal removed; the extensions exemption smuggled into the
+gate — every row KILLED at exactly its named case, restores byte-identical.
+
+## R3 verification round (1 Major + 3 Suggestions — all fixed)
+
+- **Terminal escape (F1)**: the new route sequence was reproduced red before
+  the fix — continue blocks, then managed-runtime cancel answers 409. Only the
+  A6 subtype now arms a same-Turn cancel exemption; the failed continue's
+  admission is deleted so it cannot replay as a cancel, and a durable cancelled
+  terminal lifts the block. The witness asserts the unknown fold, cancelled
+  terminal, cleared status, and public-cancel 204. The pre-existing generic
+  recovery-block control still answers 409 `turn_blocked`.
+- **Settlement status (F2)**: the settle case now selects `call-3` — the call
+  answered by the settlement's own pass, not a sibling fill — and asserts its
+  `executionStatus: 'unknown'`.
+- **Debug residue (F3)**: the command-wait case's projection `console.log` is
+  removed.
+- **Stale description (F4)**: the PR body and both design versions describe
+  the five-row matrix, all recovery writers, honest unknown folds, and the
+  bounded cancel escape rather than the pre-R2 single-guard shape.
+
+R3 delete-controls (quiet tree, one selected test per row): the first blocked
+gate, second blocked gate, continue-admission deletion, terminal block lift,
+and A6 subtype each red the block-then-cancel witness; broadening the marker
+to every family error reds exactly the generic blocked-cancel control;
+reverting the settlement status reds exactly the `call-3` case. All 7 rows
+KILLED, every restore sha256-identical.
+
+Gates: 8 focused suites, 1587/1587 (the harness file's 686 tests completed in
+two explicit groups, 175 + 511, after the default full-file run reached the
+10-minute runner limit without a test failure); typecheck RC=0; ESLint and
+Prettier green.
+
+## R4 verification follow-up (1 Suggestion — fixed)
+
+- **Journal-only workflow refusal**: the verifier's sole surviving mutation,
+  M12, narrowed `settleJournalOnlyInterruptedTurn`'s family test to
+  `call.name === 'agent'`. The existing `parkYoloWithOwedCall` fixture now has
+  a workflow sibling: with no child ledger, the takeover must keep
+  `{kind: 'declined', reason: 'model_start'}` and leave the input unsettled.
+  This is test-only; production code is unchanged.
+- M12 now reds exactly that case (`1 failed | 11 passed`, received
+  `{kind: 'inapplicable'}`), and the restored suite is 12/12. The cumulative
+  focused evidence is 9 suites, 1599 tests (the previous 1587 plus this 12-test
+  journal-only suite).

+
+父文档：[G3 Step 3 恢复](2026-10-09-hosted-g3-step3-recovery.zh-CN.md)。
+English: [2026-10-31-hosted-a6-uncertainty-evidence.md](2026-10-31-hosted-a6-uncertainty-evidence.md).
+
+## 问题
+
+A6 要求三个观察：缺失或未知的 producer 证据必须阻塞；不重建外部调用；不静默
+释放 Workspace 租约。对 main `35daec35ea` 的调查（两路并行代码调研，关键主张
+已手工复核）表明：第二、三子句已有厚实守卫与测试，第一子句存在三个具体证据
+缺口：
+
+- **G1 — Hook/MCP 保存批次拒绝臂零测试。** `resumeSavedNativeBatch` 对
+  Hook/MCP 会话拥有的非 commandStep 计划抛
+  `HostedToolRecoveryRequiredError('Unsupported saved batch owner.')`
+  （`hosted-workspace-tool-turn.ts:3508-3517`）。该字符串在任何测试中都不出现；
+  approval-continuation 夹具从不构造 hooks/mcp 的 resume。预计删掉该子句后所有
+  套件仍绿。
+- **G2 — extensions 开启的入口组合未钉。** 接管续接入口
+  （`hosted-harness-session.ts:7124-7129`）在 `session.extensions?.enabled` 时
+  即使 `session.hooks || session.mcp` 也放行；非 commandStep 计划的唯一兜底就是
+  G1 那条未测子句。（解决范围：本切片双向钉住 tool-turn 兜底；入口的
+  `extensions?.enabled` 子句本身是路由级表面，记录为下方后续工作——定向夹具
+  无法在不构造完整 hooks 会话接管的情况下触达它，而一个无法失败的用例比没有
+  更糟。）
+- **G3 — 不可得的 child 账本被当作「证明缺席」应答。**
+  `fillParkedRoundAgentGaps` 在 `children === undefined || admitted === undefined`
+  时对滞留调用折叠 `gapText`（`hosted-runtime-recovery.ts:1505-1517`）。两臂的
+  证据语义不同：账本在场时，无 `child_run` 记录是「从未启动」的肯定证据
+  （`admitLaunch` 先提交记录再 `dispatchStarted`，
+  `hosted-child-agent-session.ts:1383-1415`）；账本缺席时一无所知——折叠却断言
+  「the call never ran」（`HOSTED_AGENT_CALL_NOT_REACHED_TEXT`，
+  `hosted-workspace-tool-turn.ts:1660-1661`）。账本家族是 `agent` 与 `workflow`
+  两者：本模块其他读取点已把两个名字视为一家
+  （`hosted-runtime-recovery.ts:790, 1913`、`JOURNAL_ONLY_ANSWERABLE_TOOLS`），
+  且 workflow 准入要求 child funnel。`session.childAgents` 在加载时由
+  持久会话配置确定性重建（`hosted-harness-session.ts:6265-6307`），因此对从未
+  拥有 agent 工具的稳定配置，缺席臂不可达——但在崩溃代与恢复代之间发生
+  child 通道配置/版本漂移时可达（路由级可用 version-0 通道上的
+  `suppressChildAgents` 复现），而那恰恰可能有一个已 admit 的 child 仍在运行。
+  没有测试区分这两臂。
+
+## 已核实的代码事实（main 35daec35ea）
+
+- 三类 producer 的证据都是持久且先于 dispatch 的：Hook `hook_execution` 与 MCP
+  `mcp_operation` 记录走
+  `intent → dispatch_started → settled | outcome_unknown | not_started_proven`，
+  `dispatch_started` 在物理 dispatch 之前提交
+  （`hosted-hook-session.ts:1187-1193, 1362-1378`；
+  `hosted-mcp-session.ts:865-882`）；child run 先提交 `child_run` 再 dispatch。
+- 不确定的 Hook/MCP 结果只走 lookup（`hook-status`/状态轮询）；非 settled 的
+  lookup 提交 `recovery_blocked / outcome_unknown` 并抛家族恢复错误。未发现任何
+  重建不确定外部调用的路径（dispatch 仅从 `intent`；`reconcileEffects` 只取消
+  intent、绝不重发；child admission 证据幂等）。
+- 第三子句由持久证据而非工具列表守卫：Java 释放在任何执行行非终态时拒绝
+  （`JdbcToolExecutionRepository.hasActiveByRuntimeSession`）；后代半证据阻塞
+  退役（`ManagedRuntimeRetentionGuard.childRunUnsettled`）；CLI 快速结清要求
+  非空且全 settled 的列表。已有测试见证包括
+  `hosted-mcp-session.test.ts:846, 1762`（未知结果保留 owner/阻断替换）、
+  `hosted-hook-session.test.ts:892`（未知结果保留 mount）、
+  `HostedMonitorRunFaultGatesIT`（不确定 worker → `runtime_session_held`，
+  binding 保持 READY）。
+
+## 改动
+
+- **G1/G2（仅测试）。** 在 `hosted-approval-continuation.test.ts` 增加五行
+  owner 门矩阵：hooks 拥有与 mcp 拥有的 turn 恢复非 commandStep 保存计划时以
+  `'Unsupported saved batch owner.'` cause 拒绝；Hook owner 带
+  `extensionConfig` 且无 commandStep 也被第一臂拒绝；`configRevision` 与 turn 的
+  `extensionConfig.revision` 不再匹配的 commandStep 计划由门的第二臂拒绝；
+  版本匹配的 commandStep 计划在 hooks owner 下越过该门（其拒绝是被包装的
+  传输失败，绝非 owner cause）——钉住保住 A3 commandStep 后续可用的过度阻塞
+  方向。先实证缺口：删除 owner 门子句后改动前的套件仍绿。
+- **G3（恢复写入点 + 有边界的 cancel 出口）。** 在存活信号下，仍欠折叠的
+  账本家族调用（`agent` 或 `workflow`）若 `children === undefined`，
+  `fillParkedRoundAgentGaps`、`fillParkedRoundCommandGaps` 与 hosted
+  resumed-turn 应答都拒绝。共同的
+  `HostedChildLedgerRecoveryRequiredError` 子类型只为这种证据阻塞做路由标记。
+  已入日志缺口保持静默，非家族缺口保留既有应答，账本在场但无记录仍是
+  「从未启动」的肯定证据。预中止的终止性填充与 `'all'` 结算写入
+  `HOSTED_CHILD_LEDGER_UNKNOWN_TEXT` 和 `executionStatus: 'unknown'`，绝不伪造
+  never-ran 或 cancelled 结果。路由见证把漂移建进加载（orphan 停靠形状 +
+  `suppressChildAgents`）：continue 可重试地阻塞且无伪造折叠，随后
+  managed-runtime cancel 结算同一个被阻塞 Turn、写入 cancelled 终态、清除恢复
+  阻塞，公开 cancel 重放应答 204。其他恢复阻塞仍以 409 `turn_blocked` 拒绝
+  cancel。
+
+## 设计决定
+
+- **账本不可得时阻塞而非折叠。** A6 第一子句是证据语义问题：「未知」不得被
+  洗成「证明缺席」。折叠是持久的、要回答模型的；错误的 never-ran 断言会让一个
+  存活 child 的效果搁浅且无人欠它应答。
+- **账本家族，不止 `agent`。** `workflow` 启动走同一本 child-run 账本（本模块
+  其他读取点已把两个名字视为一家），因此同一不可得证据阻塞覆盖两者。其他
+  滞留调用保留既有缺口应答，守卫不会回归合法没有 child funnel 的会话。
+- **终止路由的 abort 豁免。** cancel 与中断结算漏斗刻意预中止该填充
+  （「立刻结算……而不是把 cancel 扣为人质」）；守卫豁免已中止信号，使这两条
+  路径永远可终止。无账本家族折叠明确说结果未知并保留记录，绝不声称调用从未
+  运行或已观察到取消。
+- **阻塞后的有边界终止出口。** 只有 A6 子类型会设置
+  `recoveryCancelPromptId`，也只有该 Turn 的 managed-runtime cancel 能越过
+  blocked 拒绝。失败的 continue admission 被删除，不能冒充 cancel 重放；只有
+  cancelled 终态持久化后才解除阻塞。其他恢复阻塞保留 409 拒绝与租约行为。
+- **不打包臂、不加续接支持。** §9.1 把 A6 归为定向或集成证据，且 native
+  continuation 按设计拒绝 Hook/MCP 会话（commandStep 后续是 A3 的另一半）。
+  打包 Hook/MCP 崩溃臂需要新的 e2e 夹具，属独立切片。
+- **租约侧观察留在范围外。** Hook/MCP profile 的 Turn 不入 HOSTED_CLEANUP 债务
+  协议（`!hooks && !mcp` 门），C3 扫描器不代还其租约；这是清理覆盖问题
+  （租约卡住不等于静默释放），在此记录为未来 C3 切片的相邻观察，而非 A6 缺陷。

+- G1/G2：owner 门删除在改动前的套件中存活（已实证的缺口），改动后使拒绝行
+  变红；移除 `!plan.commandStep &&` 恰好使版本匹配接受行变红；移除第二
+  （版本）臂恰好使版本过期行变红。不声称钉住 harness 入口的
+  `extensions?.enabled` 子句（见下方后续工作）。
+- G3：缺席账本反例在守卫前折叠「never ran」，守卫后对 `agent` 与 `workflow`
+  均抛错且不写任何折叠；账本在场/无记录臂仍折叠诚实应答；非家族缺口调用
+  不变；已入日志缺口静默重放；预中止填充与 `'all'` 结算写入未知结果，并在
+  结算自己的应答臂上钉住 `executionStatus: 'unknown'`。路由级内建漂移下：
+  continue 可重试地阻塞（409）且无伪造折叠，随后 cancel 结算同一 Turn 并解除
+  阻塞；无关恢复阻塞仍拒绝 cancel。每个新增守卫或出口子句都有使命名用例变红
+  的删除对照。
+- 定向套件在净化环境（剥离 agent 会话环境变量）下绿；typecheck/ESLint/Prettier
+  绿；生产改动只涉及恢复写入点与有边界的 cancel 出口。
+
+## 开放问题
+
+- 在路由级钉住 harness 接管入口的 `session.extensions?.enabled` 子句（需要
+  带持久 v3 续接的 hooks 会话接管夹具；它所把守的 tool-turn 兜底已双向钉住）。
+- 待 Hook/MCP e2e 夹具存在后，是否由后续切片打包 A6 故障臂（此处范围外）。
+- Hook/MCP profile Turn 的租约是否应加入清理债务协议（上文相邻 C3 范围观察）。
+
+## R2 评审轮（4 条建议——全部修复）
+
+- **兄弟写入点（R2-1）**：同一 never-ran 伪造在恢复路径的两个兄弟写入点上仍然存活。`answerAbandonedTurnCalls`（hosted 模式，即 continue 路由的 resumed-turn 应答）现在对无账本家族调用直接拒绝——调用方的家族 catch 把拒绝映射为可重试阻塞；终止性的 `'all'` 结算继续折叠，但使用诚实措辞（见下）。从不读账本的 `fillParkedRoundCommandGaps` 在存活信号下拒绝同一形状；其 continue 调用方传存活信号，cancel 与 settle 调用方预中止。
+- **诚实的豁免措辞（R2-3）**：被豁免（预中止）的折叠与 `'all'` 结算对无账本家族调用改用新的专用 `HOSTED_CHILD_LEDGER_UNKNOWN_TEXT`——「结果未知……记录保留」、`executionStatus: 'unknown'`——绝不写「never ran」也绝不写「cancelled」。漏斗仍不抛错、照常终止。
+- **家族单一事实源（R2-4）**：`CHILD_LEDGER_TOOL_NAMES = new Set(['agent', 'workflow'])` 定义在 `hosted-workspace-tool-turn.ts` 的应答常量旁；原先六处内联双名字字面量（recovery 四处、tool-turn 挂载校验两处）全部改读 `.has(name)`。不复用 `JOURNAL_ONLY_ANSWERABLE_TOOLS`——那套还包含团队名，其缺口应答是各自的 funnel。
+- **extensions 行（R2-2）**：owner 门矩阵补上了注释所声称的那一行——Hook owner + `extensionConfig` + 无 `commandStep` 被第一臂拒绝；向门里偷运 `&& !this.extensionConfig` 恰好使该行变红。
+
+R2 删除对照（安静树、完整失败清单判定）：把家族常量在守卫处挖空为仅 `agent`；移除 resumed-answer 拒绝；把 `'all'` 结算的 unknown 措辞改回；移除 command-gaps 拒绝；向门里偷运 extensions 豁免——每行恰好杀于命名用例，还原逐字节一致。
+
+## R3 验证轮（1 条 Major + 3 条建议——全部修复）
+
+- **终止出口（F1）**：修复前按新路由顺序实证变红——continue 阻塞后，
+  managed-runtime cancel 应答 409。现在只有 A6 子类型会为同一 Turn 设置
+  cancel 豁免；失败的 continue admission 被删除，不能冒充 cancel 重放；
+  cancelled 终态持久化后才解除阻塞。见证断言未知结果折叠、cancelled 终态、
+  状态清锁与公开 cancel 204。既有普通 recovery-block 对照仍应答 409
+  `turn_blocked`。
+- **结算状态（F2）**：结算用例现在精确选择 `call-3`——由结算自己的应答臂
+  处理、而非兄弟填充处理的调用——并断言其 `executionStatus: 'unknown'`。
+- **调试残留（F3）**：删除命令等待用例的 projection `console.log`。
+- **过期描述（F4）**：PR 正文与双语设计文档都改为描述五行矩阵、全部恢复
+  写入点、诚实未知折叠与有边界的 cancel 出口，不再是 R2 之前的单守卫形状。
+
+R3 删除对照（安静树、每行只选一个用例）：第一道 blocked 门、第二道
+blocked 门、continue admission 删除、终态清锁与 A6 子类型各自使
+「先阻塞再 cancel」见证变红；把标记扩大到所有家族错误恰好只使普通
+blocked-cancel 对照变红；回退结算状态恰好只使 `call-3` 用例变红。7 行全部
+KILLED，每次还原 sha256 一致。
+
+门禁：8 个定向套件 1587/1587（harness 文件的 686 个用例在默认全文件运行
+无断言失败但达到 10 分钟执行上限后，分成 175 + 511 两个显式组完成）；
+typecheck RC=0；ESLint 与 Prettier 绿。
+
+## R4 验证跟进（1 条建议——已修复）
+
+- **journal-only workflow 拒绝**：验证者唯一存活的变异 M12 把
+  `settleJournalOnlyInterruptedTurn` 的家族判断缩为
+  `call.name === 'agent'`。现有 `parkYoloWithOwedCall` 夹具现在增加 workflow
+  兄弟用例：没有 child 账本时，接管必须保持
+  `{kind: 'declined', reason: 'model_start'}` 且输入仍未结算。这是纯测试补钉，
+  生产代码不变。
+- M12 现在恰好只使该用例变红（`1 failed | 11 passed`，实际收到
+  `{kind: 'inapplicable'}`），还原后套件 12/12。累计定向证据为 9 个套件、
+  1599 个用例（此前 1587 + 本 journal-only 套件 12）。

+  Session contexts and Binding validation/invalidation helpers. The source
+  audit corrected the original three-map sketch: `bindingOperations` had to
+  move with Binding lifecycle operations, whereas execution-keyed
+  `reconciliations` stayed with `ExecutionObservationCooldown` and moved in
+  the later reconciliation slice. In the Registry slice the service retained
+  provisioning, drain, recovery, execution settlement, renewal and scheduler
+  lifecycle. This
+  established a concrete owner without injecting service callbacks. The M6
+  stamp-before-slot-removal coverage gap is addressed by the blocked-stamp
+  regression in the [execution workflow extraction](2026-11-01-runtime-execution-workflows.md),
+  which implements reconciliation, takeover scans and cancellation after
+  the Registry. The Registry slice itself does not claim that coverage.
+  See the linked bilingual designs for concurrency, cleanup and acceptance

 - Apply the same treatment to `ManagedSessionStore` and

+# Managed Runtime backend modules
+
+[English](2026-10-31-managed-runtime-backend-modules.md) | [简体中文](2026-10-31-managed-runtime-backend-modules.zh-CN.md)
+
+Status: implemented; Java acceptance pending. Based on main `73474ef094ea1c6bb2a95a9a2a33a28b0ec58e9e`, including its Store constructor injection. Scope narrowed on 2026-11-02 to independently consumable Maven backends and their assembly. The existing shared local Java verification budget is exhausted at 599.048/600 seconds; earlier Local/External results do not certify the revised SPI and module graph.
+
+## Objective and boundaries
+
+After #15871, backend implementations still share the adapters artifact and server assembly directly constructs them. SSH additionally requires a Local provider. Split Local, SSH, Kubernetes, External and Static into independent Maven artifacts so another service can depend on the server and explicitly install only its chosen backend. Preserve the default full executable and operator distributions.
+
+Backend availability comes from the application's trusted classpath; enabled selection comes from existing configuration. No live JAR loading, automatic download or untrusted-plugin isolation is introduced. Selective standalone builds, variant archives, deployment examples and their CI matrix are deferred. Kubernetes scratch, Session/Turn prewarm changes and further database/Harness/messaging dependency trimming are outside this change.
+
+## Module boundaries
+
+Modules remain reactor siblings with the same parent version and release process. Each production Java package has one artifact owner; package-private tests move with their classes.
+
+| Module               | Responsibility                                                           | Internal dependencies                                      |
+| -------------------- | ------------------------------------------------------------------------ | ---------------------------------------------------------- |
+| `contracts`          | Runtime settings, identities and construction/access ports               | None                                                       |
+| `runtime-local`      | Local Worker, persistent state, factory and offline recovery             | `contracts`, `runtime-http`, `runtime-host`                |
+| `runtime-ssh`        | SSH Worker, connections/tunnels and factory                              | `contracts`, `runtime-http`, `runtime-host`                |
+| `runtime-kubernetes` | Kubernetes client, resident/CSI provisioning, protection and reclamation | `contracts`, `runtime-http`                                |
+| `runtime-external`   | External Runtime client, scratch/workspace providers and factory         | `contracts`, `runtime-http`                                |
+| `runtime-static`     | Preconfigured endpoint/lease and factory                                 | `contracts`                                                |
+| `runtime-http`       | Shared HTTP transport                                                    | `contracts`                                                |
+| `runtime-host`       | Shared process/file exchange and host identity/state utilities           | `contracts`                                                |
+| `runtime-broker`     | Lease/execution coordination and backend-neutral routing                 | `contracts`                                                |
+| `adapters`           | Harness, filesystem and other non-provider adapters                      | Shared modules; no backend implementation                  |
+| `server`             | Selection, SQL-backed wiring, HTTP and operator entry points             | Application/shared modules; five optional runtime backends |
+| `verification`       | Tests and independent classpath/embedding fixtures; unpublished          | All production modules                                     |
+
+The five backends never depend on one another. Routing belongs to `runtime-broker`; process/file exchange shared by Local and SSH belongs to `runtime-host`, which does not install a Local provider. SQL stores, reservation transactions, retirement authorization and shared CSI application-store wiring remain in their original layers. Kubernetes Harness discovery remains a separate Harness concern. New modules declare directly used libraries and participate in the existing compilation, architecture, Checkstyle, SpotBugs, source/Javadoc and aggregate coverage gates.
+
+## Factory and dependency contracts
+
+Each backend registers `RuntimeProviderFactory` through `META-INF/services`. The registry rejects duplicate/reserved kinds, checks the selected factory and verifies the returned provider's kind. Factory construction and discovery are inert; validation checks configuration only. Preflight keeps common listener, credential and Workspace checks, then delegates provider diagnostics. Remote providers do not require a local workspace directory. Existing Local executable/state checks and External workspace warnings remain.
+
+Creation uses `create(settings, transport, dependencies)`. `RuntimeProviderDependencies` has exactly four named ports: `bindings()` for the original Broker repository, `externalStorage()` for the lazy SQL storage adapter, `csiReservations()` for the original datasource/transaction authority, and `ssh()` for borrowed node/storage lookup and connections. A backend requests only its required ports. Kubernetes retains JDBC repository, datasource identity, transaction manager and Workspace execution checks before reservation construction.
+
+The discovered SSH factory also supplies connection construction through `SshRuntimeSupport`; the Kubernetes factory supplies operator/client/protection construction through `KubernetesRuntimeSupport` and the typed `WorkspaceCsiRuntimeSpec`. These are capabilities of the same factory, with no second discovery mechanism. The internal SPI and moved implementation imports require same-version recompilation. Persisted kinds, identity bytes, SQL schema, wire protocol and recovery algorithms do not change. Only `kubernetes-workspace` is registered; `kubernetes-scratch` remains unregistered and `kubernetes` remains rejected.
+
+An additional trusted provider can implement the contract, register its factory and use `provider-options` without another server selection branch. It must preserve existing fencing, identity and HTTP contracts. Discovery does not establish whether a saved resource can be recovered; existing durable checks remain authoritative.
+
+## Selection, admission and resource lifetime
+
+`RuntimeBackendSelection` computes the enabled set before resource allocation. Disabled Broker means an empty set with no discovery or connections. SSH primary requires configured nodes and selects SSH alone. Local primary with nodes selects Local+SSH; any other primary with nodes is rejected. Otherwise only the primary backend is enabled. All selected factories and configuration are checked before clients, connections or Worker state are created.
+
+SSH-only constructs no Local provider/state or routing wrapper. Local+SSH retains its shared endpoint resolver and original node identity, while the Local delegate uses its direct HTTP transport. SSH-only refuses unbound Session execution, Local workspace settings and historical Local path resolution. Static retains directory preflight; Kubernetes retains credentials, resident registration and physical-retirement authorization.
+
+`ssh.enabled` still governs new registrations, bindings, Sessions and file access. When false, already-admitted work can execute, close, recover and perform permitted idempotent replay with its original node identity. When SSH is absent from the enabled set, historical registration queries remain available but do not claim or dispatch work, and parked acceptance stays unknown rather than becoming FAILED.
+
+Online file-upload reconciliation checks the backend of the saved target before exchange or status dispatch. A historical Local upload after switching to SSH-only stays pending and retains its storage holder without executing the saved Local command. Restoring the backend resumes reconciliation. This guard does not disable independent offline storage maintenance.
+
+Spring exclusively closes the shared SSH connections bean; providers and `SshWorkspaceService` borrow it, and the service closes only its executor. Failed startup and normal shutdown must release controller ownership. Factories close partially constructed resources; resident assembly closes earlier delegates if a later registration fails.
+
+## Maven consumption and maintenance
+
+The server declares five `optional` dependencies with `runtime` scope. Library consumers receive none transitively and explicitly add their chosen same-version backend artifacts. For example, Kubernetes requires the ordinary server and `qwen-managed-agent-runtime-kubernetes`; Local+SSH requires both corresponding artifacts. A disabled Broker needs no backend. Including several artifacts does not enable arbitrary composition or fallback.
+
+The standalone build still includes all five backends. Keep the fixed `exec` classifier, existing operator classifiers and Central-release policy, application YAML/configuration metadata and Lombok exclusion. The ordinary library contains no standalone application YAML. Keep the reference packager and release names unchanged; no backend selector or variant metadata is added. Update only module-related Maven cache exclusions and their CI meta-tests.
+
+Maintenance requests capabilities per action: missing Kubernetes rejects CSI `serve`, protection rendering and physical retirement, while CSI `text`/`retire` and SQL-only resident `inspect`/`begin` remain available. Local-dependent recovery requires Local before persistent side effects. Online validation belongs to normal configuration and explicit preflight, not shared properties initialization used by the SQL-only maintenance context. Missing capabilities never fall back to another backend.
+
+## Verification and remaining risks
+
+Keep independent compilation and bytecode dependency checks. Isolated classpaths cover absent backends, each single backend, Local+SSH, full and an independent contract-only provider; the ordinary Maven embedding fixture checks that no optional backend leaks transitively. Default executable packaging checks all five JARs and service registrations, configuration resources and operator launchers. These checks do not claim seven standalone variant products.
+
+Retain regressions for unused-provider initialization, missing/duplicate factories before side effects, SSH admission, pending upload/registration recovery, failed-startup controller lock reacquisition and partial-construction cleanup. Preserve the existing full unit/H2, Checkstyle, SpotBugs, embedding, MySQL and Hosted/fault CI gates. Real enabled SSH/Kubernetes and complete cross-platform acceptance remain required; mocked connections or H2 do not establish that evidence.
+
+New and revised Java tests await CI because the shared local budget is closed. Root script/workflow tests, formatting, link checks and static review cover the scope reduction; prior root build/typecheck/bundle evidence applies only while its inputs are unchanged. Detailed results remain in `.qwen/e2e-tests/runtime-provider-plugins.md`. Retain an owning backend until its work drains, or deliberately keep pending operations and storage claims until it is restored. No unresolved design decision blocks this scope.

+状态：已实现，Java 验收待完成。基于 main `73474ef094ea1c6bb2a95a9a2a33a28b0ec58e9e`，包含其中的 Store 构造注入改动。2026-11-02 将范围收敛为可独立引用的 Maven 后端及其装配。既有共享本地 Java 验证预算已消耗 599.048/600 秒；此前 Local/External 结果不能证明修订后的 SPI 和模块图正确。
+
+## 目标与边界
+
+#15871 之后，后端实现仍共用 adapters 产物，server 装配直接构造实现，SSH 还依赖 Local provider。将 Local、SSH、Kubernetes、External 和 Static 拆为独立 Maven 产物，使其他服务能引用 server 并显式安装所需后端。保留默认完整可执行包和运维分发。
+
+后端是否可用由应用可信 classpath 决定，启用哪个后端由现有配置决定。不引入实时 JAR 加载、自动下载或不可信插件隔离。选择性独立构建、变体归档、部署示例及其 CI 矩阵后置。Kubernetes scratch、Session/Turn 预热调整，以及进一步裁剪数据库/Harness/消息依赖不在本次范围内。
+
+## 模块边界
+

+
+五个后端互不依赖。路由属于 `runtime-broker`；Local 与 SSH 共用的进程/文件交换属于 `runtime-host`，不会安装 Local provider。SQL 存储、预留事务、退休授权及共享 CSI application-store 装配保留在原层。Kubernetes Harness 发现仍是独立的 Harness 职责。新模块直接声明使用的库，并接入既有编译、架构、Checkstyle、SpotBugs、源码/Javadoc 及聚合覆盖率检查。
+
+## 工厂与依赖契约
+
+每个后端通过 `META-INF/services` 注册 `RuntimeProviderFactory`。注册表拒绝重复/保留 kind，检查选中工厂并核对返回 provider 的 kind。工厂构造与发现不分配资源；validation 只检查配置。预检保留公共监听、凭据及 Workspace 检查，再委派后端诊断。远程后端不要求本机 Workspace 目录。保留原 Local 可执行文件/状态检查和 External workspace 警告。
+
+创建接口为 `create(settings, transport, dependencies)`。`RuntimeProviderDependencies` 只有四个具名接口：`bindings()` 提供原 Broker 仓储，`externalStorage()` 延迟提供 SQL 存储适配器，`csiReservations()` 提供原数据源/事务权威，`ssh()` 提供借用的节点/存储查询和连接。各后端只获取所需接口。Kubernetes 在构造预留存储前保留 JDBC 仓储、数据源身份、事务管理器及 Workspace 执行检查。
+
+已发现的 SSH 工厂通过 `SshRuntimeSupport` 提供连接构造；Kubernetes 工厂通过 `KubernetesRuntimeSupport` 和类型明确的 `WorkspaceCsiRuntimeSpec` 提供运维/客户端/保护构造。这些是同一工厂的能力，不增加第二套发现机制。内部 SPI 和已移动的实现 import 需要按同版本重新编译。持久化 kind、身份字节、SQL schema、协议及恢复算法不变。只注册 `kubernetes-workspace`；`kubernetes-scratch` 仍未注册，`kubernetes` 仍被拒绝。
+
+其他可信 provider 可以实现契约、注册工厂并使用 `provider-options`，无需增加 server 选择分支；它必须遵守既有 fencing、身份和 HTTP 契约。发现成功不能证明可恢复已有资源，原持久化检查仍具有决定权。
+
+## 选择、准入与资源生命周期
+
+`RuntimeBackendSelection` 在分配资源前计算启用集合。Broker 停用时集合为空，不发现工厂、不创建连接。SSH 主后端要求配置节点，只选择 SSH。Local 主后端配置节点时选择 Local+SSH；其他主后端与节点组合提前拒绝。其余情况只启用主后端。所有选中工厂及配置均在创建客户端、连接或 Worker 状态前检查。
+
+SSH-only 不构造 Local provider/状态或路由包装。Local+SSH 保留共享 endpoint resolver 及原节点身份，Local delegate 使用直接 HTTP transport。SSH-only 拒绝未绑定 Session 的执行、Local workspace 设置和历史 Local 路径解析。Static 保留目录预检；Kubernetes 保留凭据、常驻注册及物理退休授权。
+
+`ssh.enabled` 继续控制新注册、绑定、Session 和文件访问。设为 false 时，已接纳任务仍可按原节点身份执行、关闭、恢复及进行获准的幂等重放。SSH 不在启用集合时，历史注册仍可查询，但不 claim 或分发任务，暂停的 acceptance 保持 unknown，不改写为 FAILED。
+
+在线文件上传对账在交换或状态分发前检查已保存目标所属的后端。切到 SSH-only 后，历史 Local 上传保持 pending 和存储占用，不执行已保存的 Local 命令；恢复后端后可继续对账。该限制不禁用独立离线存储维护。
+
+Spring 唯一负责关闭共享 SSH connections bean；provider 与 `SshWorkspaceService` 仅借用，service 只关闭自己的 executor。启动失败与正常关闭均须释放 controller 所有权。工厂关闭部分构造的资源；常驻装配在后续注册失败时关闭此前 delegate。
+
+## Maven 引用与运维
+
+server 声明五个 `optional`、`runtime` 依赖。library 使用方不会传递引入任何后端，需要显式添加同版本的所选后端产物。例如，Kubernetes 使用方引用普通 server 和 `qwen-managed-agent-runtime-kubernetes`；Local+SSH 使用方引用对应的两个产物。Broker 停用时无需后端。安装多个产物不代表允许任意组合或回退。
+
+独立应用构建仍包含五个后端。保留固定 `exec` classifier、现有运维 classifier 及 Central 发布策略、应用 YAML/配置元数据和 Lombok 排除。普通 library 不含独立应用 YAML。保持参考打包器及发布名称不变，不增加后端选择器或变体元数据。CI 仅更新模块相关的 Maven 缓存排除及配套元测试。
+
+运维按 action 获取能力：缺少 Kubernetes 时拒绝 CSI `serve`、保护渲染和物理退休，但保留 CSI `text`/`retire` 及纯 SQL 的 resident `inspect`/`begin`。依赖 Local 的恢复在持久化副作用前要求 Local。在线校验属于正常配置及显式预检，不放入纯 SQL 维护上下文使用的共享 properties 初始化。缺少能力时不回退到其他后端。
+
+## 验证与剩余风险
+
+保留独立编译及字节码依赖检查。隔离 classpath 覆盖无后端、五种单后端、Local+SSH、full 及独立的 contract-only provider；普通 Maven 嵌入夹具检查 optional 后端不会传递泄漏。默认可执行包检查五个 JAR 及服务注册、配置资源和运维启动器。这些检查不宣称交付七种独立分发产品。
+
+保留未选 provider 初始化、缺失/重复工厂在副作用前拒绝、SSH 准入、pending 上传/注册恢复、启动失败后 controller 锁重新获取及部分构造清理的回归。保留既有完整 unit/H2、Checkstyle、SpotBugs、embedding、MySQL 和 Hosted/fault CI 检查。真实启用的 SSH/Kubernetes 及完整跨平台验收仍是必需项；模拟连接或 H2 不能替代。
+
+共享本地预算已关闭，新增及修订后的 Java 测试等待 CI。根目录脚本/工作流测试、格式、链接检查和静态审查覆盖此次收敛；仅当输入未变化时复用此前根目录 build/typecheck/bundle 证据。详细结果保留在 `.qwen/e2e-tests/runtime-provider-plugins.md`。移除后端前应排空其工作，或明确保留 pending 操作及存储占用直到原后端恢复。当前范围没有待用户决定的设计问题。

+# Runtime Binding Registry
+
+[English](2026-10-31-runtime-binding-registry.md) | [简体中文](2026-10-31-runtime-binding-registry.zh-CN.md)
+
+- Status: First implementation slice; verification results are recorded separately. Subsequent workflow extraction is described in the [execution workflow design](2026-11-01-runtime-execution-workflows.md).
+- Date: 2026-10-31
+- Source baseline: `cf7e77810efa776f29b52a3dc4bf24f17d5e80f8`.
+- Scope: module-internal extraction in `packages/managed-agent-server/runtime-broker`.
+
+## Problem and current state
+
+`RuntimeBrokerService` combines placement, acquire, execution, reconciliation, cancellation, recovery and shutdown in approximately 6,300 lines. Extracting reconciliation alone would require passing its mutable maps and numerous lifecycle callbacks into another class. The [structure review](2026-10-31-managed-agent-structure-review.md) therefore requires a state owner first.
+
+The source audit refines that proposal: `bindingOperations` belongs with Binding state because provisioning, recovery, reclamation and drain all reserve the same Binding ID. `reconciliations` belongs with execution reconciliation because its execution-ID reservation must be released only after stamping `ExecutionObservationCooldown`. Moving these two maps in the opposite direction would retain the coupling we want to remove.
+
+## Goals and boundaries
+
+Establish one module-internal owner for local Binding and Runtime Session state, migrate all production consumers, and preserve observable behavior. This slice changes no public interface, HTTP route, schema, dependency, authentication rule or protocol byte. It does not change when `warm` runs; the separate on-demand Runtime proposal is outside this change.
+
+Provisioning, attestation, drain, Session acquisition/release, execution settlement, recovery scans and renewal scheduling remain orchestrated by the service. They may use Registry operations, but the Registry never calls back into the service. Do not introduce an interface, generic operation runner, event bus or configurable lifecycle framework for this one owner.
+

Acquire, execution/control, reconciliation, cancellation, release and drain use these contexts. |
+| `reconciliations` and `ExecutionObservationCooldown`                         | Service, then a future reconciliation collaborator | Execution-ID deduplication and the existing stamp-before-reservation-removal ordering move together in a later slice.                                                                                                                              |

+
+`BindingContext` is an immutable record and lease pair used between orchestration steps. `SessionContext` retains its `ReentrantLock`: callers' compound decisions and the context's accessors use the same guard, including when repository calls block on JDK 21 virtual threads. The first slice preserves the background-process set's existing guarded use rather than changing settlement ownership at the same time.
+
+## Registry operations
+
+The Registry is package-private in the existing service package. It receives the Binding repository, provisioner, Broker owner ID, operation lease duration and clock directly. These are its concrete dependencies for the existing validation/invalidation operations; it has no scheduler and no service reference.
+
+- Look up, reserve and conditionally remove Binding-operation futures. A caller keeps the future it installed; cleanup removes that exact reservation, so an old completion cannot drop a replacement.
+- Look up, register and remove Session futures. Failed acquire/adoption removes its exact future. Successful release retains the existing removal points after durable release or an already-`RELEASED` read.
+- Register or forget a locally attested Binding, match its generation and complete lease identity, and require that local route before use.
+- Validate that an execution's original persisted generation remains `READY` or `DRAINING`. This read remains separate from local lease validation and from tenant, Harness and admission checks at their existing call sites.
+- Invalidate an unusable Binding and reject unusable Session leases with the existing error codes.
+- Cancel pending Binding and Session futures during service shutdown. The service continues to cancel dispatch and execution-reconciliation futures, stop both schedulers and close the provisioner.
+
+Raw maps never escape. Futures and contexts are operation handles, not new durable state. The Registry does not start work, refresh authorization, acquire a replacement generation or manufacture a Session on a read path.
+
+## Concurrency, leases and cleanup
+
+Preserve these source-order contracts:
+
+1. Provisioning/adoption persists readiness under the repository claim before registering the attested lease locally. Cached readiness must match generation, Runtime instance ID, endpoint, token, lease ID and epoch; a stale endpoint never becomes a fallback route.
+2. Reserve a Binding ID with `putIfAbsent` before starting the corresponding local operation. Existing callers either join or receive the same operation-specific refusal as before. Conditional reservation removal precedes completion of its owned future, preserving synchronous continuation behavior.
+3. Reserve a Session future before acquire. On failure, remove that future before completing it exceptionally. Existing Session identity/admission checks, mount-claim replacement, control counters and release guards retain their locations and lock boundaries.
+4. Invalidation first revokes the local route, then attempts a repository operation claim and the existing `READY` to `LOST` CAS. A failed claim or write must not restore the route. Release the claim in `finally`, using the exact Broker owner and operation generation; a failed best-effort release expires naturally. Invalidation alone proves neither loss evidence nor stopped writers and does not release Sessions or physical resources.
+5. Physical Session release still follows durable `RELEASING` admission, worker acknowledgement and durable release completion. Failed/negative release resets the existing latch for retry. No local cache move bypasses active-execution or background-hold checks.
+6. Service close sets the existing atomic fence before canceling Registry futures, then cancels the other operation futures, shuts down schedulers and closes the provisioner. Registry cancellation introduces no separate closed flag, teardown order or physical cleanup policy.
+
+Binding IDs name durable physical generations; repository operation generations independently fence successive owners of a claim. The extraction preserves both identities and all repository checks. Process-local futures only coalesce work inside one Broker and cannot establish cross-process exclusivity.
+
+## Implementation and follow-up sequence
+
+The first slice adds `RuntimeBindingRegistry`, moves its maps, local context types and Binding validation/invalidation helpers, and migrates every service call site. Test-only context installation follows the new owner through `BrokerServiceTestAccess`; production gains no test hook. Update both versions of the structure review to reference the corrected ownership boundary.
+
+The [subsequent workflow design and implementation](2026-11-01-runtime-execution-workflows.md) follows this sequence:
+
+1. Execution reconciliation, taking its execution-ID reservations and cooldown ordering together. Pin stamp-before-reservation-removal at that seam; this Registry slice does not claim to close the existing coverage gap; the subsequent extraction adds the blocked-stamp regression.
+2. Recovery scanning and its background-process settlement dependencies, after the reconciliation seam exists.
+3. Cancellation and its original-generation routing and durable intent handling.
+
+Each follow-up has its own diff and acceptance evidence. Moving all workflows into this Registry would merely recreate the large service under a new name.
+
+## Validation and acceptance
+
+The change is an internal refactor, so use the existing Java service and HTTP regressions instead of inventing a global CLI baseline or a new behavior E2E plan. Run focused Registry tests for full lease matching, persistent-generation eligibility, invalidation order and claim cleanup, reservation replacement and shutdown. Existing service tests cover concurrent warm/acquire/release, changed leases, stale provisioning completion, claim renewal, reconciliation routing and close fencing. Include the affected HTTP tests whose context fixtures move, durable recovery tests, the virtual-thread guard regression and module architecture checks within the module's shared local verification budget.
+
+Preflight JDK 21, Maven >= 3.8.9 and a source-matching SDK in the task's isolated Maven repository. Use the module's focused Maven test/Checkstyle command and record the exact selected classes, source state, results and omissions. Full Java/SpotBugs, MySQL and Hosted/fault gates remain CI work. Selected in-memory or H2 cases do not establish MySQL, real-process recovery or production acceptance. If the relevant real-process path cannot run locally within budget, record it as pending rather than replacing it with a fixture claim.
+
+Acceptance requires no raw Registry maps or context definitions in the service, no service dependency or injected callbacks in the Registry, unchanged external contracts and repository algorithms, meaningful focused regression evidence, two clean self-audit passes, synchronized bilingual documents and the required CI gates on the accepted revision. Local completion of the extraction alone does not mean CI acceptance.
+
+## Risks and resolved questions
+
+The main risks are changed completion order, accidental weakening of local lease checks, altered exception classification and loss of the shared context guard. Mitigate them with mechanical moves, caller-by-caller comparison and the focused tests above. Keep existing unconditional Session removal and Binding retirement points; changing their policy would be a separate behavior change.
+
+Resolved: Registry owns Binding-operation reservations, not execution reconciliation reservations. The service owns renewal and shutdown. Durable admission remains at the original repository call sites. No open product decision is required for this slice; the subsequent collaborator APIs and validation are specified in the linked workflow design.

+# Runtime Binding Registry
+
+[English](2026-10-31-runtime-binding-registry.md) | [简体中文](2026-10-31-runtime-binding-registry.zh-CN.md)
+
+- 状态：首个实现切片；验证结果单独记录。后续流程抽取见[执行流程设计](2026-11-01-runtime-execution-workflows.zh-CN.md)。
+- 日期：2026-10-31
+- 源码基线：`cf7e77810efa776f29b52a3dc4bf24f17d5e80f8`。
+- 范围：`packages/managed-agent-server/runtime-broker` 模块内部抽取。
+
+## 问题与当前状态
+
+`RuntimeBrokerService` 在约 6,300 行中混合了放置、acquire、执行、对账、取消、恢复和关闭。单独抽取对账需要向新类传递可变 map 和大量生命周期回调。因此，[结构评审](2026-10-31-managed-agent-structure-review.zh-CN.md) 要求先明确状态持有者。
+
+源码审计修正了原提案：`bindingOperations` 应与 Binding 状态归于同一持有者，因为供应、恢复、回收和排空都预留同一个 Binding ID。`reconciliations` 则属于执行对账，因为必须先写入 `ExecutionObservationCooldown`，再释放按 execution ID 预留的槽位。反向迁移这两张 map 会保留本次要解除的耦合。
+
+## 目标与边界
+
+为本地 Binding 和 Runtime Session 状态建立唯一的模块内部持有者，迁移全部生产调用方，并保持可观察行为。首片不改变公共接口、HTTP 路由、schema、依赖、认证规则或协议字节。不改变 `warm` 的调用时机；按需启动 Runtime 的独立提案不在本次范围内。
+
+供应、身份核验、排空、Session 获取/释放、执行结算、恢复扫描和续租调度仍由服务编排。它们可以调用 Registry，但 Registry 不得回调服务。不为这一个持有者引入接口、通用操作运行器、事件总线或可配置生命周期框架。

+
+`BindingContext` 是编排步骤间传递的不可变 record 与 lease 对。`SessionContext` 保留 `ReentrantLock`：调用方的复合决策与 context 访问器使用同一把锁，包括 repository 调用在 JDK 21 虚拟线程上阻塞的场景。首片保持后台进程集合现有的加锁使用方式，不同时修改结算归属。
+
+## Registry 操作
+
+Registry 是现有 service package 中的 package-private 类。直接接收 Binding repository、provisioner、Broker owner ID、operation lease duration 和 clock。这些是现有校验/失效操作的具体依赖；它没有 scheduler 或 service 引用。
+
+- 查找、预留并有条件地移除 Binding 操作 future。调用方保留自己安装的 future；清理只移除该预留项，旧操作完成不能删除替代项。
+- 查找、登记和移除 Session future。acquire/接管失败时只移除自己的 future。成功释放保留持久化释放完成或读到已 `RELEASED` 后的现有移除位置。
+- 登记或移除本地已核验的 Binding，匹配代际及完整租约身份，并在使用前要求这条本地路由存在。
+- 验证 execution 的原持久化代际仍为 `READY` 或 `DRAINING`。该读取继续独立于本地租约校验，以及原位置的 tenant、Harness 与准入检查。
+- 将不可用 Binding 标为失效，并按现有错误码拒绝不可用的 Session lease。
+- 服务关闭时取消未完成的 Binding 与 Session future。服务继续取消分发与执行对账 future、停止两个 scheduler 并关闭 provisioner。
+
+不暴露原始 map。future 和 context 是操作句柄，不是新的持久状态。Registry 不启动工作、不刷新授权、不获取替代代际，也不在读取路径上制造 Session。
+
+## 并发、租约与清理
+
+保留下列源码顺序契约：
+
+1. 供应/接管在 repository claim 下持久化就绪后，才在本地登记核验后的 lease。缓存就绪必须匹配代际、Runtime instance ID、endpoint、token、lease ID 和 epoch；过期 endpoint 不能成为回退路由。
+2. 用 `putIfAbsent` 预留 Binding ID 后才启动相应本地操作。现有调用方继续 join 或收到原有的操作特定拒绝。有条件移除预留项先于完成其持有的 future，保持同步 continuation 行为。
+3. acquire 前先预留 Session future。失败时先移除该 future，再异常完成。现有 Session 身份/准入检查、mount claim 替换、control 计数和 release guard 保留原位置与锁边界。
+4. 失效处理先撤销本地路由，再尝试 repository 操作 claim 与现有 `READY` 到 `LOST` 的 CAS。claim 或写入失败不得恢复路由。在 `finally` 中以准确的 Broker owner 和 operation generation 释放 claim；尽力释放失败时由租约自然过期。失效本身不构成丢失证据或 writer 停止证明，也不释放 Session 或物理资源。
+5. 物理 Session 释放仍按持久化 `RELEASING` 准入、worker 确认、持久化释放完成的顺序执行。失败/否定回复重置现有 latch 以便重试。本地缓存迁移不得绕过活跃 execution 或后台 hold 检查。
+6. 服务 close 先设置现有原子屏障，再取消 Registry future，随后取消其他操作 future、关闭 scheduler 和 provisioner。Registry 取消操作不引入独立 closed 标志、拆除顺序或物理清理策略。
+
+Binding ID 标识持久的物理代际；repository operation generation 独立隔离同一 claim 的历次 owner。抽取保留两种身份和全部 repository 检查。进程内 future 仅合并同一 Broker 中的工作，不能建立跨进程互斥。
+
+## 实现与后续顺序
+
+首片新增 `RuntimeBindingRegistry`，迁移其 map、本地 context 类型及 Binding 校验/失效 helper，并迁移全部 service 调用点。测试通过 `BrokerServiceTestAccess` 按新持有者安装 context；生产代码不新增测试入口。同时更新两个语言版本的结构评审，引用修正后的归属边界。
+
+[后续流程设计与实现](2026-11-01-runtime-execution-workflows.zh-CN.md) 遵循以下顺序：
+
+1. 执行对账，同时迁移按 execution ID 预留的槽位和 cooldown 顺序。在该边界固定先 stamp 后移除预留项的测试；Registry 首片不宣称补齐现有覆盖缺口；后续抽取增加阻塞 stamp 的回归。
+2. 对账边界具备之后，再拆恢复扫描及其后台进程结算依赖。
+3. 取消执行及其原代际路由和持久取消意图处理。
+
+每项后续工作独立提供 diff 和验收证据。把所有流程搬进 Registry，只会换一个名字重新形成大服务。
+
+## 验证与验收
+
+本次是内部重构，复用现有 Java service 与 HTTP 回归，不构造全局 CLI 基线或新的行为 E2E 计划。定向 Registry 测试覆盖完整 lease 匹配、持久代际资格、失效顺序与 claim 清理、预留项替换和关闭。现有 service 测试覆盖并发 warm/acquire/release、租约变化、过期供应完成、claim 续租、对账路由和关闭屏障。在模块共享本地验证预算内，包括 context 夹具迁移所影响的 HTTP 测试、持久恢复测试、虚拟线程 guard 回归和模块架构检查。
+
+预检 JDK 21、Maven >= 3.8.9，以及任务隔离 Maven 仓库中匹配源码的 SDK。按模块要求运行定向 Maven test/Checkstyle，记录准确的测试类、源码状态、结果和遗漏。完整 Java/SpotBugs、MySQL 和 Hosted/fault 门禁交由 CI。选定的内存或 H2 用例不构成 MySQL、真实进程恢复或生产验收。相关真实进程路径若无法在本地预算内运行，记录为待验证，不以 fixture 结果替代。
+
+验收要求：service 不再持有 Registry 的原始 map 或 context 定义；Registry 不依赖 service 或注入回调；外部契约和 repository 算法保持不变；具备有意义的定向回归证据；完成两轮干净自审；双语文档同步；被验收版本通过必要 CI 门禁。本地抽取完成不表示 CI 已验收。
+
+## 风险与已决问题
+
+主要风险是完成顺序变化、本地 lease 校验被意外削弱、异常分类改变，以及丢失共享 context guard。通过机械迁移、逐调用方对比和上述定向测试控制风险。保留现有无条件移除 Session 和退役 Binding 的位置；更改该策略属于独立行为变更。
+
+已决：Registry 持有 Binding 操作预留项，不持有执行对账预留项。续租与关闭归服务。持久准入保留在原 repository 调用位置。首片没有待定产品决策；后续协作者 API 和验证已在所链接的流程设计中明确。

+
+## Problem and current state
+
+The [structure review](2026-10-31-managed-agent-structure-review.md) identifies seven public setters on the Session store. Three are required Spring dependencies (`WorktreeFiles`, `ManagedSessionSkills`, `ExtensionPackages`); four are optional (`WorkspaceLifecycleStore`, `ManagedAgentDefinitionStore`, `SessionWorktreeStore`, `JournalEventTransport`). The constructor also creates a standalone skills store which Spring subsequently replaces. The object can therefore exist before its dependency assignment is complete.
+
+There is an eighth injected dependency: optional, lazy `ManagedExtensionRecordStore` field injection. It has a real cycle back through `AgentStateStore`. The skills store also has its own existing lazy resource-store dependency. The other immediate dependency constructors have no eager edge back to the Session store: lifecycle uses providers for runtime resources, definitions is JDBC/digests, worktrees uses JDBC/registry/storage guard, extension packages uses its catalog/registry/archive dependencies, and journal transport uses its messaging dependencies.
+
+## Goals and boundaries
+
+Make all eight dependency references final, assign them through construction and remove all seven setters and the injected field. Preserve required/optional Spring resolution, the lazy record-store cycle boundary, qualifiers, transactions, SQL, protocol bytes and feature-disabled behavior. Do not change adjacent stores' injection, split business logic, change schema/routes or introduce a dependency container, builder or generic provider abstraction in production.
+
+## Construction design
+
+Use one explicitly `@Autowired` constructor containing the existing seven inputs, the three required dependencies and the five optional dependencies. Required dependencies remain ordinary constructor parameters so missing Spring beans still fail startup. Optional dependencies use `@Nullable` and retain the existing null guards in business methods. Inject the record store as `@Lazy @Nullable`: the lazy proxy remains unresolved during construction, preserving the original lazy field behavior and avoiding eager resolution of its `AgentStateStore` back-reference. Do not resolve that proxy or call a dependency from the constructor.
+
+The constructor stores the injected skills instance directly; it no longer manufactures a temporary replacement. Preserve the existing qualified JDBC, mapper and clock parameters and every settings-derived field. The optional definitions, lifecycle, worktree and transport references remain concrete objects, avoiding providers whose repeated resolution could change the current null checks or dependency identity.
+
+Keep the existing seven-argument standalone constructor because two production private-CSI helpers construct a minimal store outside Spring. It delegates once to the complete constructor, supplies the same standalone skills implementation and leaves integrations absent as before. Spring selects only the annotated complete constructor. This is an existing concrete use case, not a new compatibility ladder: no setter bridge or further constructor overload is added.
+
+## Consumers and test fixtures
+
+Production component scanning continues to construct the store; the private-CSI helpers retain their existing standalone construction. The test fixture that previously added local worktree files after construction becomes a constructor factory. Its default form constructs the same standalone skills behavior and local worktree adapter. A second test-only form accepts the definitions and lifecycle objects actually configured by existing tests; those callers now provide them before construction. Keep the same transactional wrapper, settings, JDBC instance and test assertions.
+
+Migrate every `VerificationFixtures.configure(new ManagedAgentStore(...))` call to that factory. Bare standalone constructors used by read-only/private fixtures remain valid. Move the few definitions/lifecycle setup statements before factory construction; when a lifecycle fixture uses a result-store provider back-reference, register the result store after constructing the Session store, as required by that existing provider graph. Do not mutate final fields reflectively or rebuild a constructed store to emulate a setter.
+
+Spring `@Bean` factories are a separate construction path: Spring previously applied the removed setters after receiving the returned object, but it does not rerun the annotated constructor on that object. The close, retention and action test factories must therefore receive all collaborators through their method parameters and invoke the complete constructor directly, preserving required parameters, nullable optional parameters and the lazy record-store parameter. Keep their existing properties, clock and publisher choices. The standalone test factory is only for manually assembled fixtures and must not substitute for Spring assembly.
+
+## Validation
+
+Add real Spring context tests with circular references disabled. Cover all required dependencies present, each required dependency missing, optional dependencies absent, the actual record-store/Session-store cycle, lazy target resolution and transaction-proxy identity. Assert the store has no injected fields or dependency-mutating methods and that all eight dependency fields are final. Required-bean checks must exercise Spring resolution, not just constructor annotations.
+
+Load each of the three actual test factory configurations in a Spring context and verify its injected collaborator identities, deferred record-store initialization and back-reference to the completed transaction proxy. Run the existing close, retention and action scenarios as behavioral regression coverage, including the retention guard cases affected by uncaught background cleanup failures in the original CI run.
+
+Reuse the application-context admission and skills tests, definition/approval tests and lifecycle fixtures affected by setup migration. Include a representative existing complete application context so the real component assembly is exercised alongside the minimal context. Keep SQL/repository algorithms unchanged and compare method bodies outside the constructors and removed setters. Run focused Java tests and Checkstyle under the module's shared 10-minute local verification budget using JDK 21 and a source-matching SDK; full Java/SpotBugs and platform/integration qualification remain CI work. This internal assembly refactor needs no global CLI baseline or TypeScript build.
+
+Documentation verification checks both complete language versions, relative links and formatting. Self-audit the complete diff, including mechanically migrated fixtures, until two consecutive clean passes. Record selected tests and unrun gates separately; local context/H2 passes do not establish MySQL, Hosted or production acceptance.
+
+## Risks, acceptance and open questions
+
+The principal risks are making an optional bean required, eagerly resolving the record-store cycle, injecting a raw early reference instead of the transactional proxy, or changing manual fixture behavior. Preserve the lazy annotation rather than replacing it with eager `getIfAvailable`, and pin the runtime bean graph in tests. The standalone constructor's deliberately absent integrations are unchanged; the complete Spring constructor still requires its three beans.
+
+Acceptance requires all seven public setters and field injection gone, eight final dependency fields, no change to business method bodies or SQL, migrated direct callers, successful required/optional/cycle/proxy context tests and affected regression tests, complete synchronized bilingual designs and two clean self-audit passes. No product decision is open; full CI acceptance remains pending until its required gates run on the accepted revision.

+- 状态：本地已实现，定向验证通过；完整 CI 验收仍待完成。
+- 日期：2026-11-01
+- 基线：`06c1f989715fa812fc26258525ef97627c15b855`。
+- 范围：`ManagedAgentStore` 依赖装配及直接验证夹具，独立于 PR #16029。
+
+## 问题与当前状态
+
+[结构评审](2026-10-31-managed-agent-structure-review.zh-CN.md) 指出了 Session store 的七个公开 setter。其中三个是 Spring 必需依赖（`WorktreeFiles`、`ManagedSessionSkills`、`ExtensionPackages`），四个可选（`WorkspaceLifecycleStore`、`ManagedAgentDefinitionStore`、`SessionWorktreeStore`、`JournalEventTransport`）。构造器还会创建一个 standalone skills store，随后由 Spring 替换。因此，对象可以在依赖尚未装配完整时存在。
+
+另有第八处注入：可选且延迟的 `ManagedExtensionRecordStore` 字段注入。它经 `AgentStateStore` 存在真实回环。skills store 自身也有现存的延迟 resource-store 依赖。其余直接依赖的构造器不立即回调 Session store：lifecycle 经 provider 获取 runtime 资源，definitions 依赖 JDBC/digests，worktrees 依赖 JDBC/registry/storage guard，extension packages 依赖 catalog/registry/archive，journal transport 依赖消息组件。
+
+## 目标与边界
+
+将八个依赖引用全部改为 final，经构造赋值，移除七个 setter 与注入字段。保留 Spring 必需/可选解析、延迟 record-store 回环边界、qualifier、事务、SQL、协议字节和功能关闭行为。不修改相邻 store 的注入，不拆业务逻辑，不改 schema/路由，也不在生产代码引入依赖容器、builder 或通用 provider 抽象。
+
+## 构造设计
+
+使用一个显式 `@Autowired` 构造器，包含现有七个输入、三个必需依赖和五个可选依赖。必需依赖使用普通构造参数，缺少 Spring bean 时继续启动失败。可选依赖使用 `@Nullable`，业务方法保留原空值判断。record store 使用 `@Lazy @Nullable` 注入：构造期间不解析延迟代理，保留原延迟字段行为，避免立即解析其 `AgentStateStore` 回引。构造器不解析该代理，也不调用依赖。
+
+构造器直接保存注入的 skills 实例，不再制造随后被替换的临时对象。保留现有 JDBC、mapper、clock 的 qualifier，以及全部根据 settings 推导的字段。可选 definitions、lifecycle、worktree 和 transport 仍是具体对象，避免 provider 的重复解析改变当前空值判断或依赖身份。
+
+保留已有七参数 standalone 构造器，因为两个生产 private-CSI helper 在 Spring 外构造最小 store。它只委托一次到完整构造器，提供同样的 standalone skills 实现，并像以前一样不配置集成依赖。Spring 只选择带注解的完整构造器。这是已有的具体用途，不新增兼容重载链：不保留 setter 桥，也不继续添加构造器重载。
+
+## 调用方与测试夹具
+
+生产环境继续由组件扫描构造 store；private-CSI helper 保留已有 standalone 构造。原先在构造后补 local worktree files 的测试夹具改为构造工厂。默认形式构造相同的 standalone skills 行为和本地 worktree adapter。第二种仅测试形式接收已有测试实际配置的 definitions 与 lifecycle 对象，这些调用方改为构造前提供。保留相同的事务包络、settings、JDBC 实例和测试断言。
+
+将所有 `VerificationFixtures.configure(new ManagedAgentStore(...))` 调用迁到该工厂。只读/private 夹具使用的裸 standalone 构造继续有效。少量 definitions/lifecycle 配置语句移到工厂构造前；若 lifecycle 夹具通过 result-store provider 回引，则按原 provider 图在 Session store 构造后登记 result store。不通过反射修改 final 字段，不重建已构造 store 来模拟 setter。
+
+Spring `@Bean` 工厂是另一条构造路径：以前 Spring 会对工厂返回的对象继续执行已移除的 setter，但不会对该对象重新执行带注解的构造器。因此，close、retention 和 action 测试工厂必须通过方法参数接收全部协作者，直接调用完整构造器，保留必需参数、可空的可选参数和延迟 record-store 参数。各工厂原有的 properties、clock 和 publisher 选择保持不变。standalone 测试工厂只用于手工装配的夹具，不能代替 Spring 装配。
+
+## 验证
+
+新增禁用循环引用的真实 Spring context 测试。覆盖必需依赖全部存在、分别缺少各必需依赖、可选依赖缺席、实际 record-store/Session-store 回环、延迟 target 解析及事务代理身份。断言 store 没有注入字段或修改依赖的方法，八个依赖字段全部 final。必需 bean 检查必须验证 Spring 解析行为，不能只检查构造器注解。
+
+在 Spring context 中逐一加载三个实际测试工厂配置，验证注入协作者的身份、record store 的延迟初始化，以及其回引的是完成装配后的事务代理。运行已有 close、retention 和 action 场景作为行为回归覆盖，并包含原 CI 中被后台清理未捕获异常影响的 retention guard 用例。
+
+复用应用 context 准入与 skills 测试、definition/approval 测试及装配迁移影响的 lifecycle 夹具。包括一个有代表性的现有完整应用 context，以便最小 context 之外也覆盖真实组件装配。SQL/repository 算法不变，对比构造器和已删除 setter 之外的方法体。在模块共享的 10 分钟本地验证预算内，以 JDK 21 和匹配源码的 SDK 运行定向 Java 测试与 Checkstyle；完整 Java/SpotBugs 及平台/集成验收交给 CI。该内部装配重构不需要全局 CLI 基线或 TypeScript 构建。
+
+文档验证覆盖两个完整语言版本、相对链接和格式。对包含机械迁移夹具的完整 diff 进行自审，直到连续两轮干净。分别记录选中测试与未运行门禁；本地 context/H2 通过不构成 MySQL、Hosted 或生产验收。
+
+## 风险、验收与待定问题
+
+主要风险是把可选 bean 变成必需、立即解析 record-store 回环、注入原始早期引用而非事务代理，或改变手动夹具行为。保留延迟注解，不用立即 `getIfAvailable` 替换，并用测试固定运行时 bean 图。standalone 构造器刻意缺席的集成依赖保持不变；完整 Spring 构造器继续要求其三个 bean。
+
+验收要求：移除七个公开 setter 与字段注入；八个依赖字段 final；业务方法体和 SQL 不变；直接调用方迁移完成；必需/可选/回环/代理 context 测试和受影响回归通过；双语设计完整同步；两轮自审干净。没有待定产品决策；在目标修订通过所需门禁前，完整 CI 验收仍待完成。

+# Runtime execution dispatcher ownership
+
+[English](2026-11-01-runtime-execution-dispatcher.md) | [简体中文](2026-11-01-runtime-execution-dispatcher.zh-CN.md)
+
+- Status: implemented locally; focused verification passed; full CI acceptance pending.
+- Date: 2026-11-01
+- Baseline: `2aa908dc70785e38299a43964e064dbafaf7b878`, after #16029.
+
+## Problem and current state
+
+The execution workflows have explicit owners, but `RuntimeBrokerService` still owns dispatch reservations, physical invocations, dispatch-lease renewal and completion. Cancellation receives the invocation set and a per-call service callback. Moving just the transport call would leave the state and cleanup decisions split between owners.
+
+This increment extracts one package-private `RuntimeExecutionDispatcher` inside the existing runtime-broker module. It preserves the current algorithms, admission boundaries, synchronous exceptions, asynchronous completion and shutdown order. It introduces no public API, HTTP route, SQL/schema, configuration, dependency or product behavior change.
+
+The earlier full-tier run for #16029 contains an unresolved `WorkspaceCsiHostedFilesTest` cold-recovery failure before its MySQL integration phase. Preserve that evidence separately. Developing this extraction does not establish that the baseline failure is fixed or that the merged refactor has complete integration acceptance.
+
+## Ownership and consumers
+
+| Owner                          | Responsibility                                                                                                                                                                    | Direct consumers                                      |
+| ------------------------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------- |
+| `RuntimeExecutionDispatcher`   | Dispatch reservations, physical invocation membership, claim-to-EXECUTING transition, dispatch renewal, transport invocation, v3 result waiting and persisted SSH acknowledgement | Service execution/start and drain paths; cancellation |
+| `RuntimeExecutionState`        | Existing durable execution ownership, fenced settlement, UNKNOWN conversion and background-sibling settlement                                                                     | Dispatcher and existing execution workflows           |
+| `RuntimeExecutionCancellation` | Durable cancellation intent, physical cancellation and prepared-provider confirmation                                                                                             | Service cancellation facade                           |
+| `RuntimeBindingRegistry`       | Existing local Session contexts, route identity and Binding invalidation                                                                                                          | Service and execution collaborators                   |
+| `RuntimeBrokerSupport`         | Existing shared rules plus unchanged detached/no-start receipt projections and renewal-delay calculation                                                                          | Service and dispatcher                                |
+| `RuntimeBrokerService`         | Public admission and payload/grant validation, provisioning, Session/drain/stop orchestration, shared close flag, both executors and provisioner lifecycle                        | Existing adapters and assembly                        |
+
+The dispatcher borrows the existing repositories, Registry, execution state, provisioner, transport, publication verifier, clock, lease/window settings, executors and close flag. Dependencies remain explicit constructor arguments; no general context container, interface or Spring bean is added.
+
+The complete direct-consumer audit is the service's creation and two start families, its drain acknowledgement sweep and close sequence, cancellation's two invocation checks and unsent-dispatch branch, and `BrokerServiceTestAccess.pollDelay`. Other service receipt paths retain the shared `sshNoStartReceipt` and `isDetachedCapture` projections through Support. Repository and transport contracts remain unchanged.
+
+## Dispatch admission and execution
+
+Move all three `beginDispatch` overloads, `dispatch`, `enterExecuting`, reference/capture projection and `DispatchRenewal` together. Private CSI restrictions, Harness admission and deferred-payload refusal stay in their original order before reservation acquisition. Existing Session-context lock regions remain at callers; the dispatcher adds no lock around admission or dispatch.
+
+The reservation map uses `putIfAbsent` and conditional `remove(executionId, exactFuture)` on synchronous failure and asynchronous completion. It covers claim/fencing work as well as physical invocation. The distinct invocation set starts only immediately before calling transport, after renewal starts. Cancellation observes that set through `isInvoking(executionId)` rather than receiving mutable state.
+
+Preserve claim, fenced EXECUTING transition, owner/generation checks, usable-lease validation, renewal start and transport invocation in that order. A cancelled unsent execution still settles through the existing dispatcher path. Do not replace it with a new cancellation settlement algorithm or replay UNKNOWN work.
+
+On completion, remove the physical invocation marker before persisting either the settled result or UNKNOWN outcome. Preserve background-sibling settlement and best-effort SSH acknowledgement after the durable write. A transport/null-result or ordinary settlement failure retains the existing UNKNOWN mapping. Synchronous `RuntimeBrokerException` values remain unchanged; other synchronous runtime/JVM failures retain `runtime_execution_dispatch_failed` wrapping and reservation cleanup.
+
+## V3 results and SSH acknowledgement
+
+V3 result waiting is part of the dispatch call closure and moves unchanged. Keep publication-first evidence reads, dispatch/Binding identity checks, lease/deadline refusal, explicit `not_started`, detached results, non-retryable error handling and 100 ms doubling backoff capped at 2 s. The test-only backoff accessor points to the new owner.
+
+Move `acknowledgePersistedTools` into the dispatcher because dispatch completion and the service's drain sweep both consume it. Drain and physical Runtime stop remain service orchestration. Move the shared stateless `sshNoStartReceipt`, `isDetachedCapture` and `renewalDelayMillis` helpers to existing Support; do not duplicate their policies or introduce another collaborator.
+
+## Cancellation and shutdown
+
+Cancellation receives the concrete dispatcher. Replace the raw invocation-set reads with `isInvoking` and the `BiConsumer` callback with `beginDispatch(context, requested)`. Keep ownership reads, durable intent, admission refusals, control guards and physical cancellation order unchanged.
+
+The service remains the sole writer of `closed` and the owner of both executors and the provisioner. Its shutdown sequence stays: set the close fence; cancel Registry operations; cancel dispatcher reservation futures; cancel reconciler operations; shut down coordination and renewal executors; close the provisioner.
+
+`cancelPendingOperations` cancels only the existing reservation-wrapper futures. It does not cancel underlying transport stages, clear physical invocation markers or shut down borrowed resources. Do not add a new close check inside `beginDispatch`; changing the handling of already-admitted operations is outside this extraction.
+
+## Files and migration
+
+Add `RuntimeExecutionDispatcher`; update service construction/delegation, cancellation, shared Support and the test-only backoff accessor. Add focused dispatcher tests and retain the existing service, HTTP, SSH and protocol regressions. Link this design from both execution-workflow documents and update their current ownership description together.
+
+Implement after the baseline dry-run: move state and the complete dispatch closure; wire the dispatcher before cancellation; replace all direct consumers; update tests and both design languages. Keep migration mechanical and review the complete diff for accidental algorithm or exception-boundary changes.
+
+## Verification and acceptance
+
+Follow `packages/managed-agent-server/AGENTS.md`, including the shared 10-minute local verification budget, JDK 21, matching source-built SDK and isolated Maven repository. An internal Java extraction has no meaningful global-CLI behavioral probe: record the installed `qwen --version` as environment evidence only, and establish the baseline through the existing Java fixtures. No model call or JavaScript build is needed for those selected fixtures.
+
+The focused plan is recorded under `.qwen/e2e-tests/runtime-execution-dispatcher.md`. Pin reservation deduplication, synchronous-failure cleanup, invocation removal before settlement/UNKNOWN and shutdown that preserves the underlying invocation and borrowed resources. Reuse `RuntimeBrokerServiceTest`, `RuntimeSshAcknowledgementTest`, `Issue13183RegressionTest` and `RuntimeBrokerHttpServerTest` for cancellation/fencing, v3/private CSI, receipt and HTTP integration behavior. Run compilation, both Checkstyle goals and the selected tests; check actual report counts and skips.
+
+The baseline passed 280 selected tests. After extraction, the same suites plus five dispatcher cases passed 285 tests with no failures, errors or skips; both Checkstyle goals passed. Verification used JDK 21 on macOS with the source-matching SDK and isolated Maven repository. Setup, the initial unused-import Checkstyle failure and the corrected run used 252.587 seconds of the shared local budget. The cancellation witness proves preservation of the physical invocation and borrowed resources; exact wrapper cancellation is checked by source equivalence rather than a private-state test accessor.
+
+Acceptance requires one dispatch-state owner; no cancellation callback or raw invocation-set injection; unchanged public contracts/schema and dispatch algorithms; preserved close/completion order; focused regressions passing; synchronized bilingual docs; and two clean self-audit passes. Full MySQL 8.4, bundled Hosted/fault, cross-platform and full SpotBugs gates remain CI work. Local fixtures do not establish those results, and an isolated pass does not clear the earlier wider failure.
+
+## Risks and open questions
+
+The material risks are moving the invocation marker relative to settlement, changing reservation cleanup, losing original-generation routing, changing v3 deadline/receipt precedence, or taking over executor/transport cancellation. Preserve method bodies and caller lock envelopes, then exercise the existing witnesses and the new owner-focused tests.
+
+There is no open product decision. Further provisioning, Session lifecycle or persistence extraction is outside this increment. The unresolved baseline cold-recovery failure remains a separate investigation and acceptance gap.

+# Runtime 执行分发器状态归属
+
+[English](2026-11-01-runtime-execution-dispatcher.md) | [简体中文](2026-11-01-runtime-execution-dispatcher.zh-CN.md)
+
+- 状态：本地已实现，定向验证通过；完整 CI 验收待完成。
+- 日期：2026-11-01
+- 基线：`2aa908dc70785e38299a43964e064dbafaf7b878`，位于 #16029 之后。
+
+## 问题与当前状态
+
+执行流程已有明确持有者，但 `RuntimeBrokerService` 仍持有分发预留项、实际在途调用、分发租约续期及完成处理。取消流程接收在途集合和逐调用传入的 service 回调。如果只搬运 transport 调用，状态和清理决策仍会分散在多个持有者中。
+
+本增量在现有 runtime-broker 模块内抽取一个 package-private 的 `RuntimeExecutionDispatcher`。保留当前算法、准入边界、同步异常、异步完成及关闭顺序，不修改公共 API、HTTP 路由、SQL/schema、配置、依赖或产品行为。
+
+#16029 的早期完整门禁中，`WorkspaceCsiHostedFilesTest` 冷恢复用例在该任务进入 MySQL 集成阶段前失败，尚未完成根因定位。单独保留这份证据。开发本次抽取不代表已修复基线失败，也不代表已合并重构完成了完整集成验收。
+
+## 归属与消费方
+
+| 持有者                         | 职责                                                                                                                  | 直接消费方                                         |
+| ------------------------------ | --------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------- |
+| `RuntimeExecutionDispatcher`   | 分发预留项、实际 invocation 集合、claim 到 EXECUTING 的转换、分发续租、transport 调用、v3 结果等待和持久 SSH 回执确认 | service 的 execution/start 与 drain 路径；取消流程 |
+| `RuntimeExecutionState`        | 已有持久执行归属、带 fencing 的结算、UNKNOWN 转换和后台同胞行结算                                                     | 分发器及现有执行流程                               |
+| `RuntimeExecutionCancellation` | 持久取消意图、物理取消和 prepared provider 确认                                                                       | service 取消门面                                   |
+| `RuntimeBindingRegistry`       | 已有本地 Session context、路由身份和 Binding 失效                                                                     | service 与执行协作者                               |
+| `RuntimeBrokerSupport`         | 已有共享规则，以及不变的 detached/no-start 回执投影和续租间隔计算                                                     | service 与分发器                                   |
+| `RuntimeBrokerService`         | 公共准入及 payload/grant 校验、供应、Session/drain/stop 编排、共享关闭屏障、两个 executor 及 provisioner 生命周期     | 现有 adapter 与装配                                |
+
+分发器借用现有 repository、Registry、执行状态、provisioner、transport、publication verifier、clock、租约/窗口参数、executor 和关闭屏障。依赖保持为显式构造参数，不增加通用 context 容器、接口或 Spring bean。
+
+完整直接消费方清单为：service 的创建与两个 start 入口族、drain 确认扫描和关闭顺序；取消流程的两次 invocation 检查与未发送分发分支；测试辅助入口 `BrokerServiceTestAccess.pollDelay`。service 的其他回执路径通过 Support 继续使用共享的 `sshNoStartReceipt` 与 `isDetachedCapture` 投影。Repository 与 transport 契约保持不变。
+
+## 分发准入与执行
+
+将三个 `beginDispatch` 重载、`dispatch`、`enterExecuting`、reference/capture 投影及 `DispatchRenewal` 一起迁移。私有 CSI 限制、Harness 准入和 deferred payload 拒绝保留原先顺序，均在取得预留项之前执行。现有 Session context 锁区域继续位于调用方；分发器不为准入或分发新增锁。
+
+预留 map 使用 `putIfAbsent`，同步失败和异步完成时使用 `remove(executionId, exactFuture)` 条件移除。它覆盖 claim/fencing，也覆盖实际调用。独立 invocation 集合只在续租开始后、调用 transport 前登记。取消通过 `isInvoking(executionId)` 观察该集合，不再接收可变集合。
+
+保留 claim、带 fencing 的 EXECUTING 转换、owner/代际校验、可用租约校验、启动续租和 transport 调用的顺序。已取消但尚未发送的执行继续经原分发路径结算，不使用新的取消结算算法，也不重放 UNKNOWN 工作。
+
+完成时先移除实际 invocation 标记，再持久化终态结果或 UNKNOWN。保留后台同胞行结算，以及持久写入之后 best-effort 的 SSH 确认。transport 失败、空结果或普通结算异常继续映射为 UNKNOWN。同步 `RuntimeBrokerException` 原样保留；其他同步运行时/JVM 失败保留 `runtime_execution_dispatch_failed` 包装及预留项清理。
+
+## V3 结果与 SSH 确认
+
+v3 结果等待属于分发调用闭包，原样迁移。保留 publication 证据优先读取、dispatch/Binding 身份校验、租约/截止时间拒绝、显式 `not_started`、detached 结果、不可重试错误处理，以及从 100 ms 翻倍、上限 2 s 的退避。仅供测试的退避访问器改为引用新持有者。
+
+将 `acknowledgePersistedTools` 迁入分发器，因为分发完成和 service 的 drain 扫描都消费它。drain 与物理 Runtime stop 仍由 service 编排。共享且无状态的 `sshNoStartReceipt`、`isDetachedCapture` 和 `renewalDelayMillis` 迁入已有 Support，不复制规则，也不新增协作者。
+
+## 取消与关闭
+
+取消接收具体分发器，将直接读取 invocation 集合改为 `isInvoking`，将 `BiConsumer` 回调改为 `beginDispatch(context, requested)`。归属读取、持久意图、准入拒绝、control guard 和物理取消顺序保持不变。
+
+service 继续是 `closed` 的唯一写入方，并持有两个 executor 和 provisioner。关闭顺序保持为：设置关闭屏障；取消 Registry 操作；取消分发预留 future；取消对账操作；关闭协调与续租 executor；关闭 provisioner。
+
+`cancelPendingOperations` 只取消已有预留包装 future，不取消底层 transport stage，不清空实际 invocation 标记，也不关闭借用资源。不给 `beginDispatch` 增加新的关闭检查；改变已准入操作的处理方式超出本次抽取范围。
+
+## 文件与迁移
+
+新增 `RuntimeExecutionDispatcher`；更新 service 构造与委托、取消流程、共享 Support，以及仅供测试的退避访问器。新增分发器定向测试，保留现有 service、HTTP、SSH 和协议回归。为执行流程文档的两种语言加入本设计链接，同步更新当前状态归属说明。
+
+基线 dry-run 后开始实现：迁移状态与完整分发闭包；在取消流程之前装配分发器；替换全部直接消费方；更新测试及双语设计。保持机械迁移，审阅完整 diff，检查是否意外改变算法或异常边界。
+
+## 验证与验收
+
+遵循 `packages/managed-agent-server/AGENTS.md`，包括共享的 10 分钟本地验证预算、JDK 21、匹配源码构建的 SDK 和隔离 Maven 仓库。内部 Java 抽取没有有效的全局 CLI 行为探针：只记录已安装 `qwen --version` 作为环境证据，通过现有 Java fixture 建立基线。所选 fixture 不需要模型调用或 JavaScript 构建。
+
+定向计划记录在 `.qwen/e2e-tests/runtime-execution-dispatcher.md`。固定预留去重、同步失败清理、在结算/UNKNOWN 之前移除 invocation，以及关闭时保留底层调用与借用资源。复用 `RuntimeBrokerServiceTest`、`RuntimeSshAcknowledgementTest`、`Issue13183RegressionTest` 和 `RuntimeBrokerHttpServerTest` 覆盖取消/fencing、v3/私有 CSI、回执及 HTTP 集成行为。执行编译、两组 Checkstyle 和选定测试，检查实际报告数量及跳过情况。
+
+基线选定的 280 个测试通过。抽取后，同一批测试加上五个分发器用例，共 285 个测试通过，无失败、错误或跳过；两组 Checkstyle 均通过。验证在 macOS 上使用 JDK 21、匹配源码的 SDK 和隔离 Maven 仓库。环境准备、首次无用 import 的 Checkstyle 失败及修正后验证共使用本地共享预算 252.587 秒。取消用例证明实际调用及借用资源得到保留；包装 future 的准确取消动作通过源码等价核对确认，不新增访问私有状态的测试入口。
+
+验收要求：分发状态只有一个持有者；取消没有 service 回调或可变 invocation 集合注入；公共契约/schema 与分发算法不变；关闭/完成顺序不变；定向回归通过；双语设计同步；两轮干净自审。完整 MySQL 8.4、打包 Hosted/fault、跨平台及完整 SpotBugs 门禁继续由 CI 负责。本地 fixture 不构成这些结果，单独一次通过也不能消除此前更广范围的失败。
+
+## 风险与待定问题
+
+主要风险包括 invocation 标记与结算顺序改变、预留清理改变、丢失原代际路由、改变 v3 截止时间/回执优先级，以及接管 executor/transport 的取消。保留方法实现与调用方锁区域，再使用现有行为测试和新增持有者测试验证。
+
+没有待定产品决策。进一步的供应、Session 生命周期或持久化抽取不在本增量内。未解决的基线冷恢复失败继续作为独立排查项和验收缺口保留。

+# Runtime Execution Workflow Decomposition
+
+[English](2026-11-01-runtime-execution-workflows.md) | [简体中文](2026-11-01-runtime-execution-workflows.zh-CN.md)
+
+- Status: Implemented locally with focused validation passing; full CI qualification remains pending.
+- Date: 2026-11-01
+- Prerequisite: the local [Runtime Binding Registry](2026-10-31-runtime-binding-registry.md) slice on baseline `cf7e77810efa776f29b52a3dc4bf24f17d5e80f8`.
+
+## Problem, goals and scope
+
+The Registry gives Binding and Session state an owner, but execution reconciliation, takeover scans and cancellation still live in `RuntimeBrokerService`. Their shared execution reads, fenced settlement and background-hold settlement make a three-way copy of private helpers unsafe. Extract the three workflows with direct module-internal collaborators and one shared execution-state boundary. Preserve current observable behavior, including failure timing, async continuations, writer fencing and cleanup order.
+
+No public interface, HTTP route, schema, protocol, dependency or Runtime launch policy changes. Provisioning, Binding recovery/drain, Binding renewal scheduling and physical Session release stay in the service. This is structural work; full integration acceptance remains separate from implementation completion.
+
+This document records the workflow extraction merged in #16029. The [Dispatcher follow-up](2026-11-01-runtime-execution-dispatcher.md) moves dispatch reservations, invocations and completion together and replaces the original cancellation callback. The ownership table and cancellation wiring below reflect that follow-up.
+
+## Ownership and dependencies
+
+| Component                      | Owns                                                                                                                                   | Consumers                                                                                   |
+| ------------------------------ | -------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------- |
+| `RuntimeBindingRegistry`       | Existing local Binding/Session maps and contexts; READY/historical Session validation                                                  | Service and all three execution workflows                                                   |
+| `RuntimeExecutionState`        | Existing execution ownership reads, fenced dispatch settlement/UNKNOWN transitions, lapsed-claim fencing and background-row settlement | Dispatch, reconciliation, recovery, cancellation and existing acknowledgement/control paths |
+| `RuntimeExecutionReconciler`   | Execution-ID lookup reservations, `ExecutionObservationCooldown`, evidence validation and reconciliation CAS                           | Service observation endpoints and takeover scanner                                          |
+| `RuntimeExecutionRecovery`     | Bounded takeover scan and background-hold observation/sweep workflows                                                                  | Acquire/adoption, routine/drain release, background observation and task stop               |
+| `RuntimeExecutionCancellation` | Durable cancellation intent and physical cancellation/confirmation workflow                                                            | Service cancellation endpoint                                                               |
+| `RuntimeExecutionDispatcher`   | Dispatch reservations/invocations, claim transition, dispatch renewal, v3 result waiting, completion and persisted SSH acknowledgement | Service execution/start and drain paths; cancellation                                       |
+| `RuntimeBrokerSupport`         | Unchanged stateless future/error mapping, payload/reference validation, status/receipt projection and renewal-delay calculation        | The extracted collaborators and service                                                     |
+| Service                        | Public facade, `closed`, schedulers, provisioner lifetime, Binding/Session lifecycle orchestration                                     | Existing adapters and assembly                                                              |
+
+All classes remain package-private in the existing runtime-broker service package; no new interface or Spring wiring is needed. Repositories remain the sole durable authority. Context locks still belong to the Registry, and every compound read/admit/release decision retains its current lock region. The support class shares existing rules across several real callers; it is not a configurable workflow framework.
+
+## Reconciliation design
+
+Move `reconcileExecution`, automatic `observeExecution`, the context-based lookup, its execution-ID future map, the cooldown and result absorption into `RuntimeExecutionReconciler`. The service keeps the public signatures and delegates. The reconciler receives the Registry, execution-state collaborator, execution repository, provisioner, transport, publication verifier, clock, lookup duration, shared close fence and existing cooldown instance. It owns no executor and never calls the service.
+
+Keep this sequence: validate caller IDs; read owned execution; return non-UNKNOWN/terminal answers before requiring a live Session; consult a finished v3 publication if available; otherwise require the original persisted generation and locally attested route; perform a bounded status lookup. Only validated settled evidence resolves UNKNOWN, and a racing cancellation is reread before CAS. UNKNOWN or unreachable is never proof of `not_started`, never dispatches work and never provisions a Runtime.
+
+Explicit reconciliation remains fresh. Automatic observation consults cooldown first. Concurrent requests join the existing execution-ID reservation. On completion, stamp cooldown before removing that exact reservation, then complete its future; JVM Errors do not become cached UNRESOLVED answers. This order prevents a sequential caller between removal and stamping from issuing another worker request. Service close cancels the reconciler's pending reservations at the same point in the original shutdown order.
+
+Takeover lookup retains its extra close checks, original-generation routing, unresolved handling of ordinary failures/invalid status and refusal to swallow an Error. Background `not_started` settlement goes through the shared execution-state collaborator, avoiding a dependency cycle with the scanner.
+
+## Recovery scan and hold design
+
+Move `scanExecutions` into `RuntimeExecutionRecovery`, together with durable background-row pagination, fire-and-forget scan observations, routine/drain sweeps, physical hold control and the existing background observation/task-stop entry points. The dependency set is Registry, execution state, execution/session repositories, transport, reconciler and the shared close fence. It has no service callback or scheduler.
+
+The scan still reads 100-row pages scoped to the saved Session and generation, rereads each candidate before observation and yields through `thenComposeAsync` between candidates/pages. It does not claim dispatch, resend tools or isolate a record merely because it is old. Acquire waits for the execution scan but never for background maintenance observations. Listing/control failures in the background scan remain isolated from acquire.
+
+Both scan and release use the same durable background-row reader. A scan observes without `activeControls`; ordinary controls/sweeps keep their original guard accounting. The routine release sweep only observes, whereas drain alone follows status → stop → status. Only proven exit or no-start evidence settles the hold. Unknown evidence and per-row errors preserve the hold. Backfill/snapshot/removal of the context's background index retain the same lock regions. Physical Session release and its durable transitions remain in the service and call the recovery collaborator before their existing busy check.
+
+Task stop keeps tenant/Harness ownership validation and the original Session route. It may stop only the invocation's own `:process` row. No recovery path creates a replacement Binding or Session.
+
+## Cancellation design
+
+Move cancellation admission, prepared-provider confirmation, physical cancel and cancellation-result validation into `RuntimeExecutionCancellation`. It uses Registry, execution state, execution repository, transport, the concrete dispatcher, coordination scheduler, cancellation duration and close fence. Cancellation queries `isInvoking` and calls `beginDispatch` for the unsent DISPATCHING branch. It receives neither a mutable invocation set nor a per-call service callback. Do not store a service reference or pass maps/private lifecycle helpers as callbacks.
+
+Preserve terminal-receipt ownership reads before requiring a live Session. A prepared provider's cancelled receipt still requires original-worker confirmation when that worker may retain the preparation. Nonterminal cancellation persists intent before sending a worker request. Hold rows and authorized private CSI calls retain their existing refusals. An invocation still running here may receive cancellation after lease lapse; an invocation absent here first follows the repository-clock dispatch fence. UNKNOWN remains UNKNOWN until reconciliation evidence resolves it.
+
+An unsent DISPATCHING record still goes through the existing dispatcher, which reads its durable cancellation intent before deciding whether to execute; replacing that branch with a new direct settlement algorithm would change behavior. Physical cancellation status is validated and settled with the original dispatch owner/generation. A late result after claim lapse is fenced, and live-claim conflicts remain errors. Prepared-provider cancellation retains its bounded result future, 25 ms observation schedule, control accounting and refusal to treat forgotten state as confirmation.
+
+## Shared state, files and migration order
+
+`RuntimeExecutionState` moves the existing owned-execution checks, `settleExecution`, `markUnknown`, `fenceLapsedClaim`, UNKNOWN-on-closed-admission mapping and background settlement CAS loops without changing their algorithms. It receives the three repositories, Broker owner, dispatch lease and clock. `RuntimeBindingRegistry` additionally receives the existing Session repository and resolver for the READY/historical checks used across workflows; non-managed historical reads still revalidate the resolved scope, while managed history uses its saved parent identity. No resolver/admission check is dropped or moved to a cache-only path.
+
+Implement in order: shared unchanged helpers/state and Registry queries; reconciler; recovery and hold maintenance; cancellation; facade wiring and shutdown. The five new implementation files above, the existing service/Registry/cooldown documentation, test constructors and focused reconciliation regression are the affected code surfaces. Update both Registry and structure-review design pairs to link this design and distinguish the earlier slice from the new implementation. The existing contract/schema/adapters remain unchanged.
+
+## Validation and acceptance
+
+Add a deterministic reconciler-level regression for stamp-before-reservation-removal: block cooldown stamping, submit another observation during that interval and assert that it joins without a second worker lookup. Cover both an ordinary status and an ordinary lookup failure, then release the stamp and verify completion/cooldown. The witness must fail if reservation removal is moved before stamping.
+
+Reuse the existing service regressions for explicit versus automatic lookup, timeouts, malformed status, JVM Errors, publication results, concurrent cancellation and shutdown. Recovery regressions must cover multi-page takeover, generation/Session isolation, asynchronous background observations, durable-only holds and routine versus drain release. Cancellation regressions cover terminal ownership, prepared confirmation, unsent dispatch, lapsed claims, sticky intent, cross-Harness refusal and hold/CSI refusals. Keep their assertions and original ordering expectations when moving code.
+
+Within the module's shared 10-minute local verification budget, reuse the source-matching SDK and JDK 21/Maven environment, run affected Java suites with Checkstyle and the minimum subprocess path, and inspect the actual selected reports. Full MySQL 8.4, bundled Hosted/fault recovery and SpotBugs remain required CI qualification; fixture/H2 or test-worker subprocess passes do not establish those results. No JavaScript build is required because this change has no TypeScript/shared-contract change.
+
+Acceptance: all three facade entry families delegate to their named collaborators; lookup reservations and cooldown share one owner; no collaborator reaches back into service internals; cancellation uses the dispatcher without a service callback or raw invocation set; no SQL/schema/public-contract diff; moved algorithms retain their semantics; the ordering witness and focused regressions pass; bilingual documents and two clean self-audit passes are complete. CI acceptance is pending until its required gates run on the accepted revision.
+
+## Risks and open questions
+
+The main risks are altered synchronous exception mapping, completion ordering, guard accounting and cross-generation routing. Mechanical moves and unchanged call-site envelopes reduce these risks, while the existing integration tests exercise them through the public service facade. Shared immutable dependencies are passed directly rather than hidden in a generic context object.
+
+The original #16029 slice deliberately limited its callback exception to cancellation's unsent-dispatch branch. The Dispatcher follow-up replaces it with a concrete collaborator while preserving cancellation semantics and moving dispatch state and completion together. No product decisions remain open. Further provisioning or Session lifecycle extraction is outside this increment.

+- 状态：本地已实现，定向验证通过；完整 CI 验收仍待完成。
+- 日期：2026-11-01
+- 前置条件：基于 `cf7e77810efa776f29b52a3dc4bf24f17d5e80f8` 的本地 [Runtime Binding Registry](2026-10-31-runtime-binding-registry.zh-CN.md) 切片。
+
+## 问题、目标与范围
+
+Registry 明确了 Binding 与 Session 状态持有者，但执行对账、接管扫描与取消仍在 `RuntimeBrokerService` 中。它们共享执行读取、带 fencing 的结算和后台 hold 结算，不能安全地把私有 helper 复制三遍。用直接依赖的模块内部协作者拆出三个流程，并建立一个共享执行状态边界。保留当前可观察行为，包括失败时机、异步 continuation、writer fencing 和清理顺序。
+
+不修改公共接口、HTTP 路由、schema、协议、依赖或 Runtime 启动策略。供应、Binding 恢复/排空、Binding 续租调度和物理 Session 释放仍在服务中。这是结构调整；完整集成验收与实现完成分别记录。
+
+本文记录 #16029 已合并的执行流程拆分。[Dispatcher 后续设计](2026-11-01-runtime-execution-dispatcher.zh-CN.md) 将分发预留项、在途调用和完成处理一起迁移，并替换原有取消回调。下方归属表和取消装配说明反映该后续实现。
+
+## 归属与依赖

+| 组件                           | 持有职责                                                                                 | 调用方                                              |
+| ------------------------------ | ---------------------------------------------------------------------------------------- | --------------------------------------------------- |
+| `RuntimeBindingRegistry`       | 已有本地 Binding/Session map 与 context；READY/历史 Session 校验                         | 服务与全部三个执行流程                              |
+| `RuntimeExecutionState`        | 已有 execution 归属读取、带 fencing 的分发结算/UNKNOWN 转换、过期 claim 隔离和后台行结算 | 分发、对账、恢复、取消及现有确认/control 路径       |

+| `RuntimeExecutionRecovery`     | 有界接管扫描与后台 hold 观察/清理流程                                                    | acquire/接管、普通/排空 release、后台观察与任务停止 |
+| `RuntimeExecutionCancellation` | 持久取消意图与物理取消/确认流程                                                          | 服务取消入口                                        |
+| `RuntimeExecutionDispatcher`   | 分发预留项/在途调用、claim 转换、分发续租、v3 结果等待、完成处理和持久 SSH 确认          | 服务的 execution/start 与 drain 路径；取消流程      |
+| `RuntimeBrokerSupport`         | 不变的无状态 future/错误映射、payload/reference 校验、status/回执投影和续租间隔计算      | 抽出的协作者与服务                                  |
+| 服务                           | 公共门面、`closed`、scheduler、provisioner 生命周期、Binding/Session 生命周期编排        | 现有 adapter 与装配                                 |
+
+全部类保留在现有 runtime-broker service package 内，采用 package-private，不新增接口或 Spring 装配。Repository 仍是唯一持久权威。context 的锁继续归 Registry，每个复合读取/准入/释放决策保留当前锁区域。support 类只共享多个真实调用方已有的规则，不引入可配置流程框架。
+
+## 对账设计
+
+将 `reconcileExecution`、自动 `observeExecution`、基于 context 的查询、按 execution ID 索引的 future map、cooldown 和结果吸收迁入 `RuntimeExecutionReconciler`。服务保留公共签名并委托。对账器接收 Registry、执行状态协作者、execution repository、provisioner、transport、publication verifier、clock、查询时限、共享关闭屏障和现有 cooldown 实例。不持有 executor，不调用服务。
+
+保留以下顺序：校验调用方 ID；读取属于调用方的 execution；在要求活跃 Session 之前返回非 UNKNOWN/终态结果；若存在已完成的 v3 publication，则读取它；否则要求原持久代际与本地已核验路由，再执行有时限的 status 查询。只有合法的 settled 证据才能结算 UNKNOWN，并在 CAS 前重新读取并发取消。UNKNOWN 或不可达绝不构成 `not_started` 证明，不触发分发或 Runtime 供应。
+
+显式对账继续读取新状态，自动观察先读 cooldown。并发请求加入已有 execution ID 预留项。完成时先 stamp cooldown，再移除准确的预留项，最后完成 future；JVM Error 不得缓存为 UNRESOLVED。这样可防止顺序调用方在移除与 stamp 之间发起第二次 worker 查询。服务关闭在原有关闭顺序的同一位置取消对账器待完成的预留项。
+
+接管查询保留额外的关闭检查、原代际路由、普通失败/非法 status 的 unresolved 处理，以及不吞掉 Error 的规则。后台 `not_started` 结算经共享执行状态协作者执行，避免与扫描器形成依赖环。
+
+## 恢复扫描与 hold 设计
+
+把 `scanExecutions` 连同持久后台行分页、后台扫描观察、普通/排空清理、物理 hold control 和现有后台观察/任务停止入口迁入 `RuntimeExecutionRecovery`。依赖为 Registry、执行状态、execution/session repository、transport、对账器和共享关闭屏障。不回调服务，也不持有 scheduler。
+
+扫描继续按已存 Session 与代际读取每页 100 行，观察前重读候选行，并通过 `thenComposeAsync` 在候选项/页面之间让出执行。它不 claim dispatch、不重发工具，也不因记录久远就隔离它。acquire 等待 execution 扫描，但不等待后台维护观察。后台扫描的列举/control 失败仍与 acquire 隔离。
+
+扫描与 release 共用持久后台行读取。扫描观察不持有 `activeControls`，普通 control/清理保持原 guard 计数。普通 release 清理仅观察，只有 drain 执行 status → stop → status。仅已证明退出或未启动的证据能结算 hold；未知证据与逐行错误保留 hold。context 后台索引的回填、快照和移除保留原锁区域。物理 Session 释放及其持久转换仍归服务，在已有 busy 检查前调用恢复协作者。
+
+任务停止保留 tenant/Harness 归属校验和原 Session 路由，只能停止该 invocation 自己的 `:process` 行。任何恢复路径都不创建替代 Binding 或 Session。
+
+## 取消设计
+
+把取消准入、prepared provider 确认、物理取消与结果校验迁入 `RuntimeExecutionCancellation`。它使用 Registry、执行状态、execution repository、transport、具体分发器、协调 scheduler、取消时限和关闭屏障。取消流程通过 `isInvoking` 查询在途调用，并在未发送的 DISPATCHING 分支调用 `beginDispatch`，不再接收可变 invocation 集合或逐调用传入的 service 回调。不保存 service 引用，不把 map/私有生命周期 helper 作为回调传递。
+
+保留在要求活跃 Session 前读取终态回执归属的顺序。若原 worker 可能仍保留 preparation，prepared provider 的已取消回执仍需原 worker 确认。非终态取消先持久化意图，再发送 worker 请求。hold 行和已授权的私有 CSI 调用保留原拒绝规则。租约过期后，本进程仍运行的 invocation 可继续接收取消；本进程未运行的 invocation 先按 repository 时钟执行 dispatch fence。UNKNOWN 只在对账证据足够时才能结算。
+
+未发送的 DISPATCHING 记录继续走已有 dispatcher，由它读取持久取消意图后决定是否执行；用新的直接结算算法替代该分支会改变行为。物理取消 status 按原 dispatch owner/generation 校验并结算。claim 过期后的迟到结果被隔离，活跃 claim 冲突继续报错。prepared provider 取消保留有时限的结果 future、25 ms 观察调度、control 计数，以及不把已遗忘状态当作确认的规则。
+
+## 共享状态、文件与迁移顺序
+
+`RuntimeExecutionState` 原样迁移 execution 归属检查、`settleExecution`、`markUnknown`、`fenceLapsedClaim`、准入关闭时保留 UNKNOWN 的映射和后台结算 CAS 循环，不改变算法。接收三个 repository、Broker owner、dispatch lease 和 clock。`RuntimeBindingRegistry` 额外接收现有 Session repository 与 resolver，以提供跨流程使用的 READY/历史检查；非 managed 历史读取继续重验解析的 scope，managed 历史使用已存父身份。不删除 resolver/准入检查，也不把它们改成仅依赖缓存的路径。
+
+实现顺序：共享的不变 helper/状态与 Registry 查询；对账器；恢复与 hold 维护；取消；门面装配和关闭。受影响代码为上面的五个新实现文件、已有 service/Registry/cooldown 说明、测试构造器和定向对账回归。同时更新 Registry 与结构评审的两组双语设计，链接本设计并区分早期切片与本次实现。现有 contract/schema/adapter 不变。
+
+## 验证与验收
+
+增加确定性的对账器级先 stamp 后移除预留项回归：阻塞 cooldown stamp，在该窗口内再次观察，断言加入已有操作且不产生第二次 worker 查询。覆盖普通 status 与普通查询失败，再放开 stamp 并验证完成/cooldown。把预留项移除移到 stamp 前时，该测试必须失败。
+
+复用 service 回归覆盖显式/自动查询、超时、非法 status、JVM Error、publication 结果、并发取消与关闭。恢复回归须覆盖多页接管、代际/Session 隔离、异步后台观察、仅持久存在的 hold 和普通/排空 release 差异。取消回归覆盖终态归属、prepared 确认、未发送分发、过期 claim、粘性取消意图、跨 Harness 拒绝和 hold/CSI 拒绝。迁移代码时保留这些断言及原顺序预期。
+
+在模块共享的 10 分钟本地验证预算内，复用匹配源码的 SDK 和 JDK 21/Maven 环境，运行受影响 Java 测试、Checkstyle 和最小子进程路径，并检查真实选中的报告。完整 MySQL 8.4、打包 Hosted/fault 恢复和 SpotBugs 仍需 CI 验收；fixture/H2 或测试 worker 子进程通过不构成这些结果。本次无 TypeScript/共享契约变化，不需要 JavaScript 构建。
+
+验收要求：三个公共入口族委托给对应协作者；查询预留项与 cooldown 归同一持有者；协作者不访问 service 内部；取消流程直接使用分发器，不接收 service 回调或可变 invocation 集合；SQL/schema/公共契约无 diff；迁移算法语义不变；顺序回归与定向测试通过；双语文档及两轮干净自审完成。在被验收版本运行所需门禁前，CI 验收仍待完成。
+
+## 风险与待定问题
+
+主要风险是同步异常映射、完成顺序、guard 计数和跨代际路由改变。通过机械迁移和保留调用点包络降低风险，现有集成测试继续经公共服务门面验证它们。共享的不可变依赖直接传递，不隐藏在通用 context 对象中。
+
+原 #16029 切片刻意将回调例外限制在取消的未发送分发分支。Dispatcher 后续实现用具体协作者替换它，保持取消语义，并将分发状态与完成处理一起迁移。没有待定产品决策。进一步拆分供应或 Session 生命周期不在本增量范围内。

+# ManagedAgentStore and ManagedSessionStore decomposition
+
+[English](2026-11-02-managed-store-decomposition.md) | [简体中文](2026-11-02-managed-store-decomposition.zh-CN.md)
+
+## Status and scope
+
+This is the implementation contract for the accepted Store decomposition. The baseline is main `e3c7a6d7efc6df6c58ffa8ddd9c42dbb0e1784c4`. R0 ([#16061](https://github.com/QwenLM/qwen-code/pull/16061)) merged as `1bdad7d4b7949a6f8370c95965ec55901e75f67a`; its [full gate](https://github.com/QwenLM/qwen-code/actions/runs/41322812090) was still running when R1 preparation began. Merge and qualification are separate evidence. [#16029](https://github.com/QwenLM/qwen-code/pull/16029) is merged and adds no prerequisite work.
+
+R1 delivers this complete bilingual contract, the entry/transaction/caller inventory below and a lock-order audit that follows collaborators across source files. A1–A9 and B0–B6 merged together in [#16090](https://github.com/QwenLM/qwen-code/pull/16090) as `d9d6fc4a4b8e654d405dbb1d01bf3404e6435a1c`, retaining the stage ownership and acceptance checklist below. Both facades remain stable; implementation stays inside persistence. The configured full Managed Agent gate passed for its head `66d23ceb1a5bee7e9cb6362cfc238eb64297f3e6`; Store-specific macOS/Windows functional qualification remains uncovered. The cleanup follow-up below has separate acceptance evidence.
+
+Related designs: [structure review](2026-10-31-managed-agent-structure-review.md), [Agent constructor wiring](2026-11-01-managed-agent-store-wiring.md), [Maven boundaries](2026-10-29-managed-agent-maven-modules.md).
+
+## Problem and decisions
+
+The two Stores mix transaction entry points with SQL, mutable business state and several unrelated operation state machines. Moving methods by name would conceal side effects and can disable the existing single-file lock-order audit. Stable facades and explicit component ownership keep transaction behavior and callers reviewable throughout the extraction.
+
+Keep public business interfaces, DTOs, exception mapping and package-visible compatibility bridges. New collaborators are package-private `final` classes in the same package, constructed once by the facade. Add no Spring beans, Maven modules, public business interfaces, mutable dependency setup or generic Context/Support container. Existing worktree, definition and skills components retain their responsibilities.
+
+Dependencies use concrete types in one direction. Do not introduce facade callbacks or bundles of constructor functions to escape a cycle. Existing lazy Spring cycles, per-call fencing callbacks and compatibility value types keep their current meaning. If an extraction needs a shared rule, move its actual dependency closure with the first consumer; do not build unused helper frameworks.
+
+## Agent responsibility ownership
+
+| Slice | Component                  | Responsibility                                                                                                           |
+| ----- | -------------------------- | ------------------------------------------------------------------------------------------------------------------------ |
+| A1    | `AgentSessionQueries`      | Ordinary Session/Turn reads, paging, batch summaries, worktree descriptions and lifecycle presentation views             |
+| A2    | `AgentEventJournal`        | Public event writes, sequence and identity, deduplication, event reads and commit notifications                          |
+| A3    | `AgentMessageProjection`   | Materialization, message pages, coverage, replay floor and repair after retraction                                       |
+| A4    | `AgentSessionPolicies`     | Model, approval, MCP and extension admission/configuration constraints                                                   |
+| A5    | `AgentSessionCommands`     | Turn input/cancel commands, rename, general Session mutation, command receipts and settlement                            |
+| A6    | `AgentSessionAdmissions`   | Ordinary/workspace/child/internal/CSI Session admission and replay; definition, skills and worktree preparation          |
+| A7    | `AgentLifecycleOperations` | Close/archive/delete/unarchive, delivery scans and shared operation claim/retry/completion                               |
+| A8    | `AgentExecutionOperations` | Cwd, context compression, task cancellation and unknown-acceptance settlement, including compression projection backfill |
+| A9    | `AgentTurnExecution`       | Dispatch, leases, Harness admission/events, recovery wait, retries and Turn terminal state                               |
+
+`AgentStoreRows` owns shared Session/Turn row mapping and locked row reads. Commands owns shared receipts/settlement, EventJournal owns event identity and notification, and MessageProjection owns projection repair. Higher-level admission, lifecycle and execution workflows depend on these concrete lower-level collaborators. Move operation scans with their state machines.
+
+Queries must not become a facade-shaped dependency of every writer. Writers use Rows for shared row access. `contextCompressionState(s)` performs projection backfill and belongs to ExecutionOperations. `deliverableRenames` changes delivery state and belongs to Commands. Preserve unannotated writes such as `markRenameSubmitted` as unannotated entries.
+
+The worktree presentation entries `findSessionWorktree(s)` and `listSessions` can persist BLOCKED through the existing `SessionWorktreeStore` verification and its `REQUIRES_NEW` quarantine transaction. Exclude these three names from A1's pure-query slice; keep their complete implementation until A6 moves the worktree collaboration into the intended Queries presentation path. Keep that path explicitly side-effecting, reuse the existing worktree component and add no duplicate wrapper or new transaction. A1's boundary is smaller than the final Queries responsibility.
+
+## Journal responsibility ownership
+
+| Slice | Component                       | Responsibility                                                                                       |
+| ----- | ------------------------------- | ---------------------------------------------------------------------------------------------------- |
+| B0    | Existing facade construction    | Replace eight injection setters/nine references with construction-time assembly                      |
+| B1    | `JournalWriterLifecycle`        | Acquire, renew, seal, quiesce, release, block recovery and live-writer checks                        |
+| B2    | `JournalLifecycleAuthorization` | Ordinary/lifecycle authorization, approval selection and lifecycle dispatch authorization            |
+| B3    | `JournalHistoryQueries`         | Restore, paged/recent transactions, command transaction lookup and initial-journal integrity         |
+| B4    | `JournalResourceWrites`         | Instructions, skills, inherited resources, tool-result publication and resource writes inside commit |
+| B5    | `JournalResourceReads`          | Ordinary/snapshot/owner reads, verification updates, quarantine, read leases and receipts            |
+| B6    | `JournalCommit`                 | Ordinary/lifecycle commit, CSI terminal preflight/commit, associated projections and notifications   |
+
+`JournalStoreRows` owns shared row access/mapping and the integrity checks required to interpret those rows. B1 already needs activation/head checks and resource-receipt validation: migrate `activationLeaseRow`, `restoreHead`, `verifyStoredResource` and its `toolResultLimit` dependency with their first consumer. The validation can issue read-only capture/quarantine lookups; it does not stream objects, acquire read leases, quarantine objects or update verification timestamps. Those side effects remain in ResourceReads. Move other helpers only when actually used.
+
+`JournalFencing` owns credentials, writer and CSI fencing, plus bounded lock-wait error mapping. Keep its checks at their existing small-grained call sites. WriterLifecycle, LifecycleAuthorization and resource operations use Rows/Fencing; Commit depends on the concrete resource/authorization collaborators it actually calls. Do not invert the graph by making WriterLifecycle call back through the facade to HistoryQueries or ResourceReads.
+
+The existing `ensureSessionRoot` is also shared by writer acquisition and lifecycle authorization. Put this explicit, narrow root initialization in Rows when B1 first uses it: preserve its root lock and event-stream INSERT. Rows is therefore a row-access boundary, not a read-only service. Do not move writer or operation state machines into it.
+
+## Transactions, locks and atomicity
+
+Every facade entry retains its original transaction manager, propagation, isolation, read-only flag and absence of an annotation. This includes `MANDATORY`, `NOT_SUPPORTED` and `READ_COMMITTED`. Ordinary collaborator objects create no transaction proxy and introduce no `REQUIRES_NEW`. Existing programmatic transactions keep their original placement and timeout.
+
+For paths locking both Session and Turn, Session remains first. Placement, retention, root and head locks retain each path's existing order. CSI continuation exceptions and bounded lock-wait/deadlock mapping remain explicit; do not impose a new universal order.
+
+Commit resource changes, extension/action/message projections, journal transaction and head update atomically. Preserve duplicate-return positions, writer/CSI rechecks, configuration read timing and notification timing. Rollback and replay must not add notifications; standalone behavior without synchronization remains unchanged.
+
+Resource reads are not plain queries. Ordinary and snapshot reads retain their distinct verification/quarantine behavior and retention lease handling. Owner reads continue to reject an ambient transaction and use short admission transaction, object read, short recheck/receipt/cleanup transaction. Compression projection backfill keeps its programmatic transaction.
+
+Existing external `REQUIRES_NEW` boundaries remain: worktree quarantine and the snapshot caller's isolated `READ_COMMITTED` template. The ban is on introducing new transaction boundaries, not deleting those already required by callers.
+
+Do not change SQL, digests, JSON or protocol bytes, schema, HTTP/OpenAPI contracts or algorithms while extracting.
+
+## Construction and compatibility
+
+B0 resolves required dependencies at construction while retaining standalone defaults. The optional lifecycle pair remains disabled as a pair when either member is absent. CSI bindings still accept only a JDBC repository using the same data source. Update both maintenance entry points, manually assembled fixtures and factory-created Spring beans together. Verify missing required/optional dependencies, the real lazy cycle, proxy identity, actual `@Bean` factories and standalone construction.
+
+Preserve publication/snapshot methods, `PublicationWriter`, `TerminalCandidate`, same-data-source checks and existing static lock tools on the original facade. CSI terminal credential checks, preflight and commit must use the same physical connection bound to the caller's authorization. Agent CSI admission/credential bridges and static binding mapping also remain compatible. Exact bridge ownership is listed in the entry inventory.
+
+## Lock-audit implementation
+
+Keep the JDK parse-tree audit and its bounded resolution model. Load the facade with the same-package `Agent*.java` or `Journal*.java` collaborator family, rather than depending on a manually updated per-class allowlist. Other persistence files retain their existing boundary scan. New SQL-bearing files must still change the exactly pinned sibling populations visibly.
+
+Harvest members across the selected files using owner, name and parameter types. Keep source-specific imports and constant environments separate; qualify shared constants so one file cannot overwrite another file's SQL spelling. Cross-check parsed members against compiled classes for every selected source, including collaborators and nested types.
+
+Follow a field receiver only when the reference is final and its declared class is a parsed concrete final type. Resolve each field type in its declaring class. Support bare fields and explicit `this.field`; parameters/locals shadow bare fields without shadowing explicit field access. An external imported type must not borrow members or SQL constants from a same-named parsed collaborator. Keep unresolved, polymorphic, overload-ambiguous, generic/local-class and deferred-body cases fail-closed when a candidate reaches a Session lock or Turn row. Do not broaden ambiguity exemptions or delete population assertions to make moved code pass.
+
+Retain current facade entry sets, transaction checks, sibling boundary sets and ambiguity/deferred-body assertions. Collect entry populations under their facade owner so a same-named collaborator cannot satisfy them; order, ambiguity and compiled-member checks still cover the whole source family. Regression examples must cover a multi-file transitive delegate, moving the Session lock after Turn access, removing the lock entirely (caught by the pinned locker population), hiding it behind an unresolved receiver, shadowing, ambiguous overloads and file-specific constants/imports.
+
+The audit establishes source-level ordering, not transaction runtime semantics or database deadlock freedom. Each implemented stage still needs its relevant runtime and MySQL evidence.
+
+## Implementation checklist
+
+This table is the sole stage checklist, mirrored completely in the Chinese version. The entry inventory is its method-level detail, not another independent status list. Update both languages with each stage's implementation, exact tested revision, relevant evidence and remaining gaps. The stages are delivered together; none is accepted merely because its code has moved.
+

+## Validation and release criteria
+
+R1 has no CLI/HTTP behavior change: a global CLI baseline and model calls do not exercise this source audit. Use synthetic multi-file fixtures and the real persistence source tree, compile the verification module, run `SessionRowLockOrderTest` and reactor Checkstyle. Check bilingual structure, links, formatting and the complete diff. Follow the module's shared local Java budget, preserve failures and reuse only unchanged inputs; a new SHA or continuation does not reset it. Prior 272-case wiring evidence does not qualify this changed checker.
+
+Historical local evidence is retained under `.qwen/investigations/managed-store-split-implementation/`: R1 passed 56 focused lock-audit cases and eight reactor Checkstyle checks; A1–A9/B0–B6 passed 260 distinct cases in 17 completed suites after two wiring-fixture repairs. Both later bounded Maven commands timed out, and the original shared ledger remains 598.655/600 seconds. Those local commands are not relabeled as successful; their then-pending checks are addressed by the subsequent baseline CI evidence below. Historical R0 failures remain archived without independent reclassification.
+
+The [full Managed Agent gate](https://github.com/QwenLM/qwen-code/actions/runs/41426848917) passed for #16090 head `66d23ceb1a5bee7e9cb6362cfc238eb64297f3e6`. Its actual test merge was `61979c75f943e7383748c75beed02cf1dde977e5`; all 86 changed blobs matched the head. Unit/H2: 6,098 cases, 17 skipped; MySQL 8.4.6: 1,242 cases, no skips; Hosted: 167 cases, four skipped; fault: 45 cases, no skips; Hosted process gates: two cases, no skips; O4: 59 cases, no skips. All completed with zero failures/errors. The 59 lock-audit cases, six production SpotBugs checks, eight reactor Checkstyle checks, Hosted failover and both EventTransport profiles passed. Skipped cases are not passes. The macOS/Windows lanes compiled the reactor and ran SDK/Runtime Broker tests, not Store functional suites; that platform gap remains explicit. This evidence qualifies the merged baseline's configured gates and does not qualify later cleanup changes, real clusters or deployment.
+
+The cleanup follow-up starts from main `73474ef094ea1c6bb2a95a9a2a33a28b0ec58e9e`. It removes 18 redundant collaborator default overloads and three unused internal methods. Facade entries supply exactly the original defaults directly to the full-parameter collaborator methods, preserving signatures, transaction attributes and dispatch through the collaborator rather than another facade overload. Message rows map directly to `ItemRecord`; `List.copyOf` preserves the previous immutable page list. The optional Rows forwarding cleanup remains deferred. Architecture guards reject Spring meta-annotations including `@Service`/`@Repository` and SQL keywords regardless of case, with negative fixtures; a paging assertion protects list immutability. Only the deleted `beginLifecycle/9` member and `ItemRow.toRecord/0` exemption leave the lock audit; facade populations, compiled-member coverage and fail-closed negative cases remain intact.
+
+Cleanup local verification passed 232 cases across 14 selected suites with zero failures, errors or skips, including all 59 lock-audit cases and five decomposition cases. All eight reactor Checkstyle checks passed. Static substitution checks confirm the same 18 canonical default paths and 633 other parsed member bodies unchanged; these checks are not runtime evidence. The initial trailing-blank-line Checkstyle failure was repaired and retained in the cleanup investigation. Later source edits only adjust comments and call wrapping; final Checkstyle and default-path checks cover those edits. Full verify, SpotBugs, real MySQL, Hosted/fault and the new revision's full gate remain pending CI; Store-specific macOS/Windows functional qualification remains uncovered. The cleanup is a separately requested change after #16090 merged, with its own shared 600-second local budget; the original PR's ledger and evidence remain unchanged and do not qualify the new inputs.
+
+Qualification of each implemented stage must cover tenant/actor isolation, cursor semantics and batch query counts; admission/replay including definition/skills/worktree; sequence/dedup/projection gaps/retraction/replay floor; after-commit notification and rollback/replay silence; lease generation/token/expiry and unknown-acceptance non-redispatch; atomic journal rollback/replay; resource corruption/read-lease invalidation and owner-read cleanup; publication/snapshot lock order and CSI same-connection atomicity.
+
+Use real MySQL evidence for SQL/concurrency paths. CI owns full verify, SpotBugs, complete MySQL, Hosted/fault and cross-platform checks. The current push-time fast tier omits required qualification; the full Managed Agent gate on the accepted revision is the release criterion. Keep every unrun gate explicit.
+
+Each slice needs two consecutive clean complete-diff self-audits and independent review. At final completion both facades contain only assembly, transaction entries and compatible forwarding, with no business SQL or state machine. Collaborator instance dependencies are acyclic; public contracts and all path-specific transaction semantics are preserved. A green focused test is not full acceptance.
+
+## Risks and open decisions
+
+The accepted architectural direction has no outstanding product decision. The main implementation risks are hidden query side effects, shared receipt/resource validation, lazy construction cycles, moved transaction boundaries and source-audit blind spots. Resolve an unexpected dependency in the smallest affected slice and update both language versions before changing the design. Do not silently absorb an algorithm, SQL, storage or protocol redesign into a movement PR.
+
+## Implemented dependency boundaries
+
+The facade evaluates the same settings and catalog validation once, in the original order, then supplies the same values and dependency instances to final collaborator fields. Agent construction is Rows → Queries/EventJournal → Policies/Projection → Commands → Admissions/Lifecycle/TurnExecution → ExecutionOperations. Journal construction is Rows → Fencing → WriterLifecycle/HistoryQueries/LifecycleAuthorization/ResourceWrites/ResourceReads → Commit. No collaborator receives a facade or a constructor callback bundle.
+
+Shared Session/Turn point reads live in Rows; Queries forwards its three compatible point-read entries to those implementations. Policies owns shared admission predicates, while Rows owns their existing key encoders and database-time reads. The nine-argument default Session admission remains the original interface-default forwarding entry on the facade, preserving virtual dispatch and its transaction boundary. Resource row verification remains separate from object IO, leases and quarantine. Commit calls the extracted lifecycle-dispatch authorization block at its original location, with the existing call-local resource reader.
+
+Session construction now resolves all nine former setter references. The required Spring dependencies remain required; standalone constructors retain their original null/in-process/unbound defaults. Either missing lifecycle dependency disables both. Only a same-data-source JDBC runtime binding repository enables CSI. Maintenance entry points and fixtures supply dependencies before constructing downstream consumers; actual Spring factory construction is covered separately.
+
+The lock audit keeps its facade populations and pins the 23 remaining migrated private-helper overloads by owner/name/arity after deleting the unused `beginLifecycle/9`. Companion sources are analyzed with their complete family and retain separate, explicit SQL-owner boundary populations. Compiled-member coverage, fail-closed receiver resolution and the original negative regressions remain required. The original-line inventories below refer to the recorded baseline, not the new source locations.
+
+## Agent entry inventory
+
+Source: `packages/managed-agent-server/persistence/src/main/java/com/alibaba/qwen/code/managedagent/persistence/ManagedAgentStore.java`.
+
+Transaction legend: **T** = exact plain `@Transactional` (default REQUIRED, DEFAULT isolation, readOnly false), facade class retains `@Qualifier("managedAgentTransactionManager")`; **M** = same with explicit MANDATORY; **RR** = explicit transactionManager `managedAgentTransactionManager`, readOnly true, REPEATABLE_READ; **N** = no declarative transaction on the current entry. N is not a promise of read-only behavior or permission to add a transaction. The worktree rows separately name their existing verification/quarantine transaction.
+
+All overloads are listed by their source lines. Two constructors remain facade assembly; public static `readBinding` stays available at the facade and may forward to rows. Typed production callers below were cross-checked against actual receiver declarations, with the CSI local `var` construction path checked separately; an empty entry is explicitly marked rather than implying that the method can be removed. Tests remain consumers even where production does not currently call a compatibility entry.

+
+Inventory covers **136 distinct entry names / 153 declarations**, including two package-private CSI bridge methods and one public static mapper, excluding two constructors.
+
+### Worktree display decision and side effects
+
+The worktree display entries are NOT pure reads. `findSessionWorktree` / `findSessionWorktrees` call `SessionWorktreeStore.descriptor(s)` (107-145), and `listSessions` calls `descriptors` after its batched page SQL (4645). `verifiedDescriptor` (112-120) verifies filesystem identity and reads the current branch; on `ManagedAgentException` it calls `blockIdentity` (368-378), which opens an EXISTING `TransactionTemplate` with `PROPAGATION_REQUIRES_NEW`, changes READY to BLOCKED and increments revision. The separate transaction deliberately survives a caller's failed admission rollback. Final decision: exclude these three entry names from the first A1 pure-query slice and retain their original facade implementation until A6. In A6 they move to the existing AgentSessionQueries component as explicitly side-effecting compatibility display paths, reusing SessionWorktreeStore validation/quarantine and its existing transaction. Do not add readOnly, omit verification, copy quarantine code, remove the existing transaction, or add another worktree wrapper.
+
+The same existing worktree verification path appears in policy/execution admission through `requireCwdChangeRegistryFacts` (3894): `SessionWorktreeStore.requireReady` then `hasExecutionRegistryFacts`. Preserve worktree verification before the creator/binding facts check, including its persisted quarantine semantics.
+
+### Transaction and bridge exceptions
+
+- `findWorkspaceCreateReplay` (555) has no declaration; `replayWorkspaceSessionCommand` (570) has plain `@Transactional`. Both re-check replay digest, internal-team-lead identity, workspace binding and current read permission. Do not normalize the two transaction modes.
+- `insertCsiSessionCommand` (582) is package-private, has no transaction annotation, explicitly requires an active transaction, and rejects journal event transport. `requireCsiRequest` (633) preserves the same transport isolation, locks Session plus runtime-request key and validates the CSI profile/request identity. The caller `WorkspaceCsiSessionCommands.create` (19-47) rejects an ambient transaction, starts a fresh 10-second TransactionTemplate, checks its original physical transaction connection, locks placement then retention, verifies registration, then calls both Store bridges on that connection. This caller uses the standalone `var sessions = new ManagedAgentStore(...)` construction path.
+- `requireCsiRequest` is also called by `WorkspaceCsiRuntimeAccess.request` (183-190); preserve all pre-existing continuation/retention lock behavior in that caller. Keep its facade method/package visibility and the seven-argument standalone constructor available.
+- `readBinding` (7569) is public static and directly used by `WorkspaceMigrationMain`, `WorkspaceMigrationStore` and `WorkspaceFileStore`; keep a facade forwarding entry even after moving actual mapping into rows.
+- `requireMcpSettingsCommit` (1215) and `requireConfigurationCommit` (1266) are MANDATORY. `requireContextCompressionCommit` (3200) has NO annotation; it is called from `ManagedExtensionRecordStore` in an existing commit flow, and must not acquire an invented MANDATORY/REQUIRES_NEW wrapper.
+- `findMessagePage` overloads (5234/5242) explicitly use managedAgentTransactionManager, readOnly true and REPEATABLE_READ. Ordinary Query entries are unannotated and must remain so.
+- `deliverableRenames` (1933) is a transactionally mutating scan: it parks expired SUBMITTED claims and resets expired PREPARING ones before selecting work. `markRenameSubmitted` (1979) is a guarded write with no declarative transaction. Keep both in Commands and preserve the difference.
+- `contextCompressionState` (3005) calls `ensureCompactionProjection` (3066); a missing projection opens a default TransactionTemplate with a DataSourceTransactionManager and replays journal rows. Batch `contextCompressionStates` (3020) may fall back to this write path and marks unavailable states. Both belong in A8, with the same programmatic transaction, rather than A1.
+- `publishAfterCommit` (7489) publishes only after synchronization commit; if no synchronization exists it publishes immediately. Empty events do nothing. The EventJournal extraction must retain the standalone fallback and avoid replay/rollback notifications.
+
+### Actual lock families (do not replace them with one global order)
+
+- Row helper `requireSessionForUpdate` (7061/7066) locks the PUBLIC Session row first and reads/locks its event-stream counters only AFTER that lock. The list mapper and the strict single-session mapper have different missing-stream behavior. `requireTurnForUpdate` (7106) then locks a Turn where that path needs both; its NOT_FOUND mapping must survive extraction.
+- Many admission/mutation/policy entrypoints begin `WorkspaceMigrationAdmission.lockTenant`, then Session/stream, then Turn/receipt/operation as required. MCP/extension idle rechecks (1340) specifically use fresh locking reads in this order: Session plan -> active Turn -> unsettled child-run record -> requested action records -> active operation/rename/receipt. Existing journal snapshots are the reason these may not become ordinary consistent reads.
+- Lifecycle admission `beginLifecycle` (2695) locks migration tenant, conditionally retention tenant, then Session/stream; it preserves failed-operation replay/resume, authorizes state, checks idle journal, writes operation/fence/head and event in original order. `completeOperation` (4143) first applies the legacy CSI guard, then conditionally placement and bounded retention, then deletion lock either before or after Session according to lifecycle protocol, then operation claim. Do not normalize its branches.
+- `ManagedLegacySessionGuard.requireLegacyMutation` itself performs the indexed CSI root locking read through `ManagedSessionStore.namedRootDeadlock`, with a 10-second query timeout. Some Turn lease paths use this guard plus a guarded UPDATE, while admission/terminal paths take a full Session/stream lock and then Turn. Retain that distinction; a generic row-helper transaction/lock would change semantics.
+- Materialization and replay-floor advancement lock Session/stream before inspecting Turn evidence or updating coverage. Retraction repair `rebuildTurnText` (6172) locks stream coverage and message rows only after the enclosing Turn workflow has acquired its existing owner/epoch locks.
+
+### A1 dependency closure and boundaries
+
+The A1 ordinary subset needs JdbcTemplate, configured ObjectMapper, HarnessRules (approval-rule decoding), the construction-time immutable modelCatalog snapshot and Session/Turn mappers. WorktreeFiles and the three worktree display entries are deferred to the A6 -> AgentSessionQueries delivery. Shared row work is `readSession`, sessionMapper/sessionListMapper, turnMapper/turnSummaryMapper, readBinding, nullable/additive column helpers, StreamCounters and the existing locked Session/Turn readers; move each only when first actually needed, preserving strict-vs-list stream behavior and all schema projections. JSON decoding is only shared where a concrete row mapper needs it, not by introducing a generic Support/Context object.
+
+`findLatestTurns` selects by last turn.accepted event rather than latest gmt_create. The A6 `listSessions` migration must preserve tenant/actor grants, archive/title/cursor filters, limit+1 semantics, batched worktree metadata and validation/quarantine; keep query counts, ordering and byte representation. `findSessionById` is an existing cross-tenant lookup for runtime resolution; do not silently add tenant filtering or expose it as a new HTTP operation.

+Point read/display views can live in Queries; operation WORK SCANS remain with their state machine (rename -> Commands, materialization/replay floor -> Projection, compression/task cancel/parked -> ExecutionOperations, lifecycle dispatch -> LifecycleOperations, Turn dispatch/recovery -> TurnExecution). Read-only Session busy predicates shared across policies/commands/lifecycle should be given one narrow owner when first migrated; do not force a component to call the facade simply to reuse them.
+
+### Concrete one-way seams for later slices
+
+- A2 EventJournal owns appendEvent/appendEvents, event identity/source-key handling, eventMapper and after-commit publishing; it can depend on Rows, not on workflow components. It does not perform message materialization synchronously.
+- A3 MessageProjection owns projection scan/materialization/replay-floor state and the `rebuildTurnText` repair helper. Its dependency on event reads is one-way toward EventJournal/Rows. Public `retractContinuationOutput` (6009) and both `retractHarnessTurnOutput` overloads (6079/6087) remain A9 workflow entries: owner/lease/epoch checks and event/identity deletion happen before A3 repair, in the same facade transaction. Do not give Projection a callback to TurnExecution or to the facade.
+- A4 policy transactions have their own existing actor-scoped SET_MODEL/SET_APPROVAL replay protocol, using ManagedReceipts directly (4790 onward, 4954 onward). They do not call generic insertCommand/settleTurnCommand. Preserve those scopes and existing result JSON rather than rewriting them onto a new generic receipt flow. A4 may use Queries/Rows/EventJournal and existing definitions/skills; later Commands/Admissions use the policy checks in one direction.
+- A5 Commands owns common `insertCommand` (7156/7163/7170), `settleTurnCommands` (2477), `settleTurnCommand` (2532), turn command operation inserts (2416), command replay and receipts. A9 recordAdmission/recordRecoveryAdmission/recordHarnessEvents and terminal paths call this settlement seam. A8 accepted-outcome reconciliation must use the same command/rename settlement semantics; no reverse callback from Commands to A8/A9.
+- A6 Admissions depends on lower policy/command/event/row components plus existing definitions/skills/worktree components. It must preserve replay-before-new-resolution timing, creator/child scope, definition pinning and rollback behavior.
+- A7 LifecycleOperations owns operation point reads, replay/claim/lease/retry/completion and the operation mapper. Current shared APIs are used by SessionLifecycleCoordinator plus ActionResponseCoordinator and TaskCancelCoordinator. Keep their facade routing stable. A8 calls A7's operation lookup/common claim primitives where needed: for example claimContextCompression (3186) writes its specialized CAS then reads findOperation; requireContextCompressionCommit (3200) checks the same operation through that lookup. The coordinator already chooses whether to call generic completion or specialized cwd/task-cancel settlement; A7 must NOT become a dispatcher calling A8/A9.
+- A8 ExecutionOperations owns specialized cwd/compaction/task-cancel/unknown-acceptance state machines and their scans, with downward dependencies on Rows/Queries/Policies/Commands/EventJournal and A7's shared operation primitives. Generic claim/retry does not acquire a callback for specialized outcomes.
+- A9 TurnExecution needs Rows/Queries, common Commands settlement, EventJournal and Projection repair. It has no reason to depend on LifecycleOperations merely because coordinators separately call lifecycle APIs. Preserve that separation rather than installing a cycle.
+- Acyclic instance construction is an explicit acceptance test for each extraction, not a claim proven by these broad labels. In particular, shared predicate helpers such as hasOpenOperation/hasOpenExecutionOperation/hasPendingRenameDelivery and existing schema key encoders must not produce Policies -> Commands -> Policies or Commands -> Lifecycle -> Commands cycles; migrate the actual dependency closure and use the existing schema/receipt helpers directly where appropriate. No constructor function bundle, facade callback or mutable setter is needed.

+## Journal entry inventory
+
+Baseline: `e3c7a6d7efc6df6c58ffa8ddd9c42dbb0e1784c4` (2026-11-02). `M:<line>` below refers to `packages/managed-agent-server/persistence/src/main/java/com/alibaba/qwen/code/managedagent/persistence/ManagedSessionStore.java`, which has 3,931 lines. Other unqualified class filenames refer to the same persistence package; the controller is in server and the Hosted connector is in adapters. This inventory defines migration boundaries; it does not establish that subsequent slices are implemented or accepted.
+
+### 1. Decisions and boundaries
+
+- The implementation has 27 public business signatures under 22 names, all declared by the existing contracts `repository.ManagedSessionStore`. It also has three constructors, eight assembly setters holding nine references, 17 package-private methods, two package-private records and one lock-timeout constant. All are accounted for below.
+- This Store has no `MANDATORY` method. Do not assign the overall design's `MANDATORY` requirement to a Journal entry that does not have it. Journal's explicit transaction exceptions are the two `READ_COMMITTED` history queries and the `NOT_SUPPORTED` initial-journal check, plus resource reads and package bridges without declarative transactions.
+- New internal objects must not call the facade. Resource-row integrity checks and activation-row mapping needed by B1 move into `JournalStoreRows` with their first actual consumers, so B1 requires neither future B3/B5 components nor facade callbacks. Object reads, leases, verification-time updates and quarantine remain outside Rows.
+- Preserve the public business interface, package entry points, `PublicationWriter`, `TerminalCandidate`, static lock helpers and constant on the facade. Exposing internal helpers within the package supports explicit typed dependencies; it must not introduce a generic Context or Support object.
+- Preserve path-specific lock sequences. Ordinary heartbeats do not acquire tenant guards; CSI continuations lock the root before placement/retention guards; publication and snapshot paths have their own preceding legacy probes and caller-held locks. Do not replace these paths with one enforced global sequence.
+
+### 2. Transaction legend
+
+`T`: the original method has `@Transactional`. Preserve manager resolution through the class-level `@Qualifier("managedAgentTransactionManager")` (M:82); the method annotation does not name a manager explicitly. Propagation is `REQUIRED`, isolation `DEFAULT`, `readOnly=false`, with default timeout and rollback rules. Preserve the annotation on each overload; an existing self-call does not create another proxy boundary.
+
+`RO`: the same manager, `REQUIRED` / `DEFAULT` / `readOnly=true`.
+
+`RC`: the same manager, `REQUIRED` / `READ_COMMITTED` / `readOnly=true`. Internal calls to `restore` are currently self-calls and must not acquire a new transaction after extraction.
+
+`NS`: the same manager, `NOT_SUPPORTED` / `DEFAULT` / `readOnly=true`; suspend an ambient transaction without opening a new one.
+
+`N`: no declarative transaction. Extraction must not add a proxy or annotation. An existing caller determines whether a transaction is active. Standalone construction never automatically applies Spring method transactions.
+
+`P`: an `N` outer method with the programmatic owner-read flow described in section 6.
+
+Lock traces below retain existing order and branches. Repeated acquisition of an already-held lock is abbreviated, not authorized for removal. In lock columns, `P` means the placement tenant guard; `Tg` the output-publication retention tenant guard; `R` the session root; `H` the managed-session head; `D` the harness drain head; and `C` the CSI binding/slot/retirement/progress lock closure on the original connection. Bounded tenant waits remain five seconds. `namedRootDeadlock` continues to translate only its existing deadlock cases.

+
+All constructors and these eight setters originally have no declarative transaction (`N`). The three existing constructors at M:177/181/187 are `(JdbcTemplate)`, which creates extensionRecords; `(JdbcTemplate, extensionRecords)`, which uses actions=null; and Spring's `(qualified JdbcTemplate, extensionRecords, actions)`, whose three dependencies are required. Their constructor chain creates one DataSourceTransactionManager for the existing ToolPublicationRetentionStore and ownerReads template, with ownerReads timeout=10. Preserve both programmatic transaction objects and their configuration; do not replace them with new Spring beans or an additional global transaction-manager dependency.
+
+There are only two production manual callers: `server/.../maintenance/WorkspaceCsiRuntimeMain:106–107`, using bare construction plus same-DataSource CSI bindings, and `WorkspaceCsiWorkerAckMain:53–54`, using bare construction plus SdkHarnessRules. Their defaults and use cases differ; do not replace both with a common fixture that enables additional dependencies.
+
+The central manual-test path is `VerificationFixtures.configure(ManagedSessionStore):40–46`, which currently assigns only HarnessRules and StorageReadPolicy. B0 replaces it with an explicit construction factory, as with Agent wiring; do not mutate final fields reflectively, rebuild an already-created instance, or merely rename setters. The current scan covers 52 files and 150 construction points, consisting of two production and 148 verification calls, plus 16 explicit setter calls in 11 files. Check each constructor argument, original setter condition and fixture construction order during migration. Refresh the inventory during implementation: eliminating old assembly calls proves only their removal, not behavioral correctness.
+
+No current explicit `@Bean` factory returning ManagedSessionStore was found. `ToolPublicationAsyncVerificationTest:317` does have `.withBean(ManagedSessionStore.class, () -> fixture.sessions)`, in a context that also supplies HarnessRules, StorageReadPolicy, credentials, bindings and object storage. Migrate the constructed fixture rather than relying on postprocessing to apply removed setters. Add an actual @Bean factory regression in B0 to prevent recurrence of #16061's missing-dependency failure.
+
+Dependency inspection: ManagedToolResultStore:40 depends on EventProjectionStore, implemented by the Agent facade; WorkspaceExecutionStore:38 depends on jdbc, transaction manager, WorkspaceStorageGuard and settings; LiteTopicEventTransport:45 depends only on producer/provider/topic. These edges do not justify adding a new lazy cycle for B0. Preserve the existing Agent→records and skills→records lazy edges. Full Spring context, transaction-proxy and actual factory tests remain required.
+
+### 6. Actual resource-read effects and transactions
+
+#### Ordinary and snapshot reads
+
+The shared implementation at M:1930 first validates scope, credential, resource identity, head and read grant. The read grant itself reads retention state and database time. `outputRetention.read` (ToolPublicationRetentionStore:379) uses its existing TransactionTemplate, with default REQUIRED/DEFAULT/readOnly=false, to execute Tg→R→H through lockGenericSession and insert a 120-second `ma_read_lease`. It joins an existing ambient transaction. The outer resource method has no NOT_SUPPORTED annotation; do not add one.
+
+Ordinary reads use findResource with lock=true, verify the row, update last_verified_at (M:1953), and read an object stream for TOOL_PUBLICATION. Length/digest failures quarantine capture/resource state. Snapshot reads use lock=false, do not update verification time and do not quarantine, but still insert, conditionally renew, check and close retention leases. Neither belongs in a pure-query component. `verifyStoredResource` itself does not perform those effects; see section 8.
+
+The snapshot caller's existing isolated template at `ManagedNativeJournalSnapshots:56–61` uses REQUIRES_NEW + READ_COMMITTED. Its admission/basis (:89), build (:92), lease close (:94) and resource read (:520) retain that template. **Preserve this existing REQUIRES_NEW behavior.** The prohibition on introducing REQUIRES_NEW forbids additional boundaries; it does not authorize deleting this one or copying it into the new components.
+
+#### Owner reads
+
+M:1978 rejects both `isActualTransactionActive()` and an already-bound jdbc DataSource resource. Non-CSI traffic at M:1995 still falls back to the ordinary reader. The CSI path remains:
+
+1. The ownerReads template at M:197–200 uses the same-DataSource manager, REQUIRED/DEFAULT/readOnly=false and a ten-second timeout. Admission runs lockCsiContinuation→original admission or DRAINING checkpoint-continuation check→R/H→read grant→resource metadata FOR UPDATE. Require inline storage, construct identity evidence, recheck CSI/read lease, insert the OPEN CSI_RESOURCE_READ receipt, recheck again, insert ma_read_lease with generation=0, and retain the receipt.
+2. After leaving that transaction, fetchNativeResource at M:2172 obtains a separate DataSource connection to SELECT the complete inline bytes with a ten-second statement timeout. This independent reading stage must not hold the admission transaction or reuse its physical connection.
+3. finishNativeRead at M:2199 opens another short ownerReads transaction. Relock continuation/original→R/H→read receipt FOR UPDATE; changed identity/receipt is rejected. Unknown fetch failure records UNKNOWN / jdbc_fetch_unknown and retains the lease under the existing path. On a returned fetch, lock/check the read lease, lock resource metadata, compare row identity/bytes/hash, recheck CSI/read grant, update verification time, record RETURNED with verified or the refusal code, and delete the lease only after the final recheck. Existing early fencing failures roll back rather than forcing settlement; do not replace this with unconditional finally cleanup.
+4. A RuntimeException/Error during fetch attempts completion and attaches completion failure as suppressed before rethrowing the original error. Do not wrap owner IO in a large transaction or collapse repeated current-time/read-grant checks.
+
+### 7. Commit atomicity, CSI rechecks and notification
+
+Ordinary/lifecycle commit at M:1118–1459 retains one complete entry transaction. Command replay at M:1176–1214 returns before new resource/projection writes. CSI replay first validates the current writer, activation replay and current time; ordinary replay still rejects a v2 lifecycle claim. Duplicates emit no event.
+
+A new commit validates the head/generation/lease, performs native preflight when required for commitFileHistory, toolIntent or commitCheckpoint, then reads database time again to recheck the writer (M:1228–1245). `commitResources` at M:2809 executes its supplied writeFence after reading each existing resource and before writing. This is an existing call-scoped callback and may remain; it must not become a constructor-supplied collection of functions.
+
+The same transaction then applies the declared-resource census, checkpoint/history/Hosted closure validation, HostedCleanupReferences, lifecycle-dispatch authorization at M:1313 using the paired execution/session dependencies, extensionRecords.apply/applyNative, CSI acceptCommit plus another writer check at M:1343–1367, and actions.apply. requireCsiWriterCurrent runs before journal INSERT (M:1378) and again before head UPDATE (M:1421), followed by tool-result capture and ManagedUserMessageStore.capture. Resource, projection, journal and head writes must not acquire separate commits.
+
+`publishJournalAfterCommit` at M:1466 is called only at the end of a new commit (M:1455). Null transport does nothing. Without synchronization, standalone operation publishes immediately; with synchronization, register afterCommit. Rollbacks and replays do not notify. CSI continuation/terminal requires isolated journals through requireCsiJournalIsolation (M:3245), rejecting transport, so terminal commit has no notification. Do not add one to unify commit paths.
+
+The three connection-aware CSI terminal bridges use the existing ten-second transaction created by `WorkspaceCsiApplicationStore.tx:402–410` and its physical connection's bounded proxy. Preserve the authority's connection identity, DataSourceUtils.getTargetConnection and isConnectionTransactional checks; a new connection, same-URL check or helper-owned transaction is not equivalent. Preflight also verifies same-DataSource JdbcRuntimeBindingRepository. commitCsiTerminal compares frozen bytes, repeats preflight, executes authority-time/writer fencing for every resource, fences again before journal INSERT and SEALED-head CAS, and checks authority time before returning. Preserve TerminalCandidate's request, proof and token-hash values.
+
+### 8. Shared closure and one-way dependencies
+
+`JournalStoreRows` is limited to existing row access, mapping, integrity checks required when reading rows, fixed key/byte constraints, and the explicitly listed narrow row initialization below. It is not purely read-only and must not become generic business Support.

+
+B1 Fencing owns credentials, writer/read grants, placement, CSI continuation/current-time/lease/history-owner checks and lock-error mapping. `checkLifecycleWriter` (M:266), `requireNoLifecycleClaim` (M:482), `requireOrdinaryAdmission` (M:490), and lifecycleFenced/protocolFenced (M:498/510) are shared low-level gates used by writer/resource/commit paths and move into Fencing with their first consumers. B2 LifecycleAuthorization owns the three business authorization entries and the commit policy that authorizes a new lifecycle effect for dispatch; it does not call back into WriterLifecycle. ensureSessionRoot is explicitly assigned to Rows' narrow initialization boundary for its two existing consumers. Do not create Support or move writer state machines there.
+
+The final instance dependency graph is: Rows at the bottom; Fencing→Rows; WriterLifecycle→Rows/Fencing; LifecycleAuthorization→Rows/Fencing plus the existing paired execution/session dependencies; HistoryQueries→Rows/Fencing; ResourceWrites→Rows/Fencing; ResourceReads→Rows/Fencing plus existing retention/object storage; Commit→Rows/Fencing/LifecycleAuthorization/ResourceWrites plus existing extensionRecords/actions/toolResults/transport. Commit's reader callback calls Rows.storedResource directly; writeFence retains its existing call-scoped form. The facade constructs each new object once with final fields. Do not pass the facade or introduce Spring beans. Existing external static lock calls through facade compatibility symbols do not introduce instance callbacks.
+
+commitResources belongs to B4's commit-internal resource writing boundary. Share ValidatedResource through a narrow package-visible value type, including an equivalent nested type if appropriate, without changing its shape. validateCommit remains B6 protocol/full-commit validation; the shared resource value type does not justify moving it early into generic Rows. During B4, the existing facade commit calls ResourceWrites for the complete resource closure; ResourceWrites must not call back into the facade for queries or locks.

+# ManagedAgentStore 与 ManagedSessionStore 拆分设计
+
+[English](2026-11-02-managed-store-decomposition.md) | [简体中文](2026-11-02-managed-store-decomposition.zh-CN.md)
+
+## 状态与范围
+
+本文是已接受 Store 拆分方案的实施契约。基线为 main `e3c7a6d7efc6df6c58ffa8ddd9c42dbb0e1784c4`。R0（[#16061](https://github.com/QwenLM/qwen-code/pull/16061)）已作为 `1bdad7d4b7949a6f8370c95965ec55901e75f67a` 合入；R1 准备开始时，其 [full gate](https://github.com/QwenLM/qwen-code/actions/runs/41322812090) 仍在运行。合并和验收是两份独立证据。[#16029](https://github.com/QwenLM/qwen-code/pull/16029) 已合入，没有额外前置工作。
+
+R1 交付完整双语契约、下文入口/事务/调用者清单及跨文件锁检查。A1–A9 与 B0–B6 已在 [#16090](https://github.com/QwenLM/qwen-code/pull/16090) 中一并合入，合并提交为 `d9d6fc4a4b8e654d405dbb1d01bf3404e6435a1c`，保留下文逐阶段归属和验收清单。两个 facade 保持稳定，实现仍位于 persistence 内。其 head `66d23ceb1a5bee7e9cb6362cfc238eb64297f3e6` 已通过配置内的 full Managed Agent gate；Store 专项 macOS/Windows 功能资格仍未覆盖。下文精简后续改动单独记录验收证据。
+
+相关设计：[结构评审](2026-10-31-managed-agent-structure-review.zh-CN.md)、[Agent 构造装配](2026-11-01-managed-agent-store-wiring.zh-CN.md)、[Maven 边界](2026-10-29-managed-agent-maven-modules.zh-CN.md)。
+
+## 问题与决策
+
+两个 Store 把事务入口、SQL、可变业务状态和多个不同的操作状态机混在一起。按方法名称搬移会掩盖副作用，也可能使原有单文件锁顺序检查失效。保留稳定 facade 和明确组件归属，使整个提取过程中的事务行为和调用者可以逐项评审。
+
+保留公共业务接口、DTO、异常映射及包可见兼容桥接。新增协作者均为同包、包可见的 `final` 类，由 facade 构造一次。不增加 Spring Bean、Maven 模块、公开业务接口、可变依赖装配或通用 Context/Support 容器。已有 worktree、definition 和 skills 组件继续承担原职责。
+
+组件通过明确类型单向依赖。不为绕开回环新增 facade 回调或构造函数集合。现有 lazy Spring 回环、调用内 fencing 回调和兼容值类型保持原语义。提取需要共享规则时，随首个实际消费者迁移完整依赖闭包，不提前建设未使用的 helper 框架。
+
+## Agent 职责归属
+
+| 切片 | 组件                       | 职责                                                                                  |
+| ---- | -------------------------- | ------------------------------------------------------------------------------------- |
+| A1   | `AgentSessionQueries`      | 普通 Session/Turn 读取、分页、批量摘要、worktree 描述及生命周期展示视图               |
+| A2   | `AgentEventJournal`        | 公共事件写入、序号与 identity、去重、事件读取及提交通知                               |
+| A3   | `AgentMessageProjection`   | 物化、消息分页、覆盖进度、replay floor 及撤回后的修复                                 |
+| A4   | `AgentSessionPolicies`     | model、approval、MCP、extension 的准入与配置提交约束                                  |
+| A5   | `AgentSessionCommands`     | Turn 输入/取消命令、rename、一般 Session mutation、命令回执与结算                     |
+| A6   | `AgentSessionAdmissions`   | 普通/workspace/child/内部/CSI Session 准入和重放；definition、skills 与 worktree 准备 |
+| A7   | `AgentLifecycleOperations` | close/archive/delete/unarchive、投递扫描及共用 operation claim/retry/completion       |
+| A8   | `AgentExecutionOperations` | cwd、context compression、task cancel 和接受结果未知的结算，含 compression 投影补写   |
+| A9   | `AgentTurnExecution`       | dispatch、租约、Harness admission/events、恢复等待、重试及 Turn 终态                  |
+
+`AgentStoreRows` 持有共享 Session/Turn 行映射与加锁读取。Commands 持有共享回执/结算，EventJournal 持有事件 identity 和通知，MessageProjection 持有投影修复。高层准入、生命周期和执行工作流依赖这些明确的下层协作者。操作扫描与对应状态机一起迁移。
+
+Queries 不能成为每个 writer 都依赖的另一个 facade。writer 通过 Rows 共享行访问。`contextCompressionState(s)` 会补写投影，归 ExecutionOperations。`deliverableRenames` 会更新投递状态，归 Commands。保留 `markRenameSubmitted` 等写入口原本没有事务注解的行为。
+
+worktree 展示入口 `findSessionWorktree(s)` 和 `listSessions` 会通过已有 `SessionWorktreeStore` 校验及其 `REQUIRES_NEW` 隔离事务持久化 BLOCKED。这三个名称不进入 A1 的纯查询首片；完整实现保留到 A6 将 worktree 协作迁入既定 Queries 展示路径。明确该路径具有副作用，复用现有 worktree 组件，不新增同用途包装或事务。A1 的边界小于最终 Queries 职责。
+
+## Journal 职责归属
+
+| 切片 | 组件                            | 职责                                                                       |
+| ---- | ------------------------------- | -------------------------------------------------------------------------- |
+| B0   | 现有 facade 构造装配            | 将八个注入 setter 涉及的九个引用改为构造确定                               |
+| B1   | `JournalWriterLifecycle`        | acquire、renew、seal、quiesce、release、block recovery 及 live-writer 检查 |
+| B2   | `JournalLifecycleAuthorization` | ordinary/lifecycle 授权、approval selection 及生命周期派发授权             |
+| B3   | `JournalHistoryQueries`         | restore、分页/近期事务、command transaction 查询及初始 journal 完整性      |
+| B4   | `JournalResourceWrites`         | instructions、skills、继承资源、tool result 发布及 commit 内资源写入       |
+| B5   | `JournalResourceReads`          | 普通/snapshot/owner 读取、验证更新、隔离、读取租约与回执                   |
+| B6   | `JournalCommit`                 | 普通/lifecycle commit、CSI terminal 预检/提交、关联投影与通知              |
+
+`JournalStoreRows` 持有共享行访问/映射，以及解释这些行所需的完整性检查。B1 已需要 activation/head 检查和资源回执校验：`activationLeaseRow`、`restoreHead`、`verifyStoredResource` 及其 `toolResultLimit` 依赖随首个消费者迁移。这些校验可以进行只读 capture/quarantine 查询，但不读取对象流、不获取读取租约、不隔离对象，也不更新验证时间戳；这些副作用留在 ResourceReads。其他 helper 仅在实际使用时迁移。
+
+`JournalFencing` 持有凭据、writer 和 CSI fencing，以及有界锁等待错误映射。检查保留在原有的小粒度调用点。WriterLifecycle、LifecycleAuthorization 和资源操作使用 Rows/Fencing；Commit 依赖实际调用的明确资源/授权组件。不让 WriterLifecycle 经 facade 回调 HistoryQueries 或 ResourceReads 来倒置依赖图。
+
+现有 `ensureSessionRoot` 同时被 writer 获取和生命周期授权使用。B1 首次需要时，将此明确且窄的 root 初始化放入 Rows，保留 root 锁及 event-stream INSERT。因此 Rows 是行访问边界，不是只读服务；不把 writer 或 operation 状态机放进去。
+
+## 事务、锁与原子性
+
+每个 facade 入口保留原 transaction manager、传播方式、隔离级别、readOnly 及无注解行为，包括 `MANDATORY`、`NOT_SUPPORTED` 和 `READ_COMMITTED`。普通协作者不创建事务代理，不引入 `REQUIRES_NEW`。原程序式事务的位置和超时保持不变。
+
+同时锁 Session 和 Turn 的路径继续 Session 在前。placement、retention、root、head 保留各路径的现有顺序。CSI continuation 例外和有界锁等待/死锁映射单独保留，不引入新的统一全局顺序。
+
+资源变更、extension/action/message 投影、journal transaction 和 head 更新原子提交。保留重复提交返回位置、writer/CSI 复核、配置读取时点和通知时点。回滚和重放不新增通知，无同步上下文的 standalone 行为不变。
+
+资源读取不是纯查询。普通和 snapshot 读取保留各自的验证/隔离行为及 retention 租约。owner read 继续拒绝环境事务，保持短事务准入、对象读取、短事务复核/回执/收尾。compression 投影补写保留程序式事务。
+
+保留已有外部 `REQUIRES_NEW` 边界：worktree 隔离及 snapshot 调用者的独立 `READ_COMMITTED` 模板。禁止的是新增事务边界，不是删除调用者已经依赖的边界。
+
+提取过程中不改变 SQL、摘要、JSON 或协议字节、schema、HTTP/OpenAPI 契约及算法。
+
+## 构造装配与兼容
+
+B0 在构造时解析必需依赖，并保留 standalone 默认值。可选 lifecycle 双依赖任一缺失时仍两者均不启用。CSI bindings 仍只接受同一数据源上的 JDBC repository。两个维护入口、手工夹具和工厂创建的 Spring Bean 一起迁移。验证必需/可选依赖缺失、真实 lazy 回环、代理身份、实际 `@Bean` 工厂及 standalone 构造。
+
+publication/snapshot 方法、`PublicationWriter`、`TerminalCandidate`、同数据源检查和已有静态锁工具继续从原 facade 提供。CSI terminal 凭据检查、预检和提交必须使用调用方授权绑定的同一物理连接。Agent CSI 准入/凭据桥接及静态 binding 映射也保持兼容。精确桥接归属见入口清单。
+
+## 锁检查器实现
+
+保留基于 JDK 语法树的检查及有界解析模型。加载 facade 与同包的 `Agent*.java` 或 `Journal*.java` 协作类族，不依赖手工逐类更新的允许列表。其他 persistence 文件保留已有边界扫描。新增包含 SQL 的文件仍须显式改变精确固定的 sibling 集合。
+
+跨选定文件按 owner、名称和参数类型采集成员。各文件的 import 和常量环境独立；共享常量使用限定名，避免一个文件覆盖另一文件的 SQL 文本。每个选定源文件及嵌套类的解析成员都与编译后的类交叉核对。
+
+只追踪引用为 final、声明类型是已解析的具体 final 类的字段接收者。字段类型按声明它的类解析。支持裸字段及显式 `this.field`；参数/局部变量遮蔽裸字段时不能遮蔽显式字段访问。外部导入类型不能借用同名已解析协作类的成员或 SQL 常量。不可解析、多态、重载歧义、泛型/局部类和延迟执行体只要候选涉及 Session 锁或 Turn 行，继续按失败处理。不通过扩大歧义豁免或删除集合断言让搬移后的代码通过。
+
+保留现有 facade 入口集合、事务检查、sibling 边界集合，以及歧义/延迟执行体断言。入口集合按所属 facade 采集，不能由协作类的同名方法满足；锁顺序、歧义及编译成员覆盖仍检查整个协作类族。回归覆盖多文件传递委托、把 Session 锁移到 Turn 访问之后、完全删除锁（由固定的 locker 集合捕获）、隐藏到不可解析接收者、遮蔽、歧义重载及文件独立的常量/import。
+
+检查器证明源码层面的顺序，不证明运行时事务语义或数据库无死锁。后续切片仍需相应运行时及 MySQL 证据。
+
+## 实施清单
+
+此表为唯一阶段清单，英文版本完整同步。入口清单是其方法级明细，不另立独立状态表。两种语言同步记录各阶段实现、精确验证版本、相关证据和未完成项。各阶段一起交付；代码已迁移不代表已验收。

+## 验证与交付标准
+
+R1 不改变 CLI/HTTP 行为，全局 CLI baseline 或模型调用无法验证此源码检查器。使用多文件合成夹具和真实 persistence 源码树，编译 verification 模块，运行 `SessionRowLockOrderTest` 及 reactor Checkstyle。检查双语结构、链接、格式和完整 diff。遵守模块共享本地 Java 预算，保留失败记录，只复用输入未变的证据；新 SHA 或继续会话不会重置预算。此前 272 个装配用例不能验收改动后的检查器。
+
+历史本地证据保存在 `.qwen/investigations/managed-store-split-implementation/`：R1 的 56 个定向锁审计用例及八个 reactor Checkstyle 通过；A1–A9/B0–B6 修复两项装配夹具失败后，17 个已完成测试类中的 260 个不同用例通过。后期两次受限 Maven 调用均超时，原共享账本保持 598.655/600 秒。这些本地命令不改判为成功；当时待补的检查由下文后续基线 CI 证据覆盖。历史 R0 失败仍归档保留，不单独重新归因。
+
+[#16090 的 full Managed Agent gate](https://github.com/QwenLM/qwen-code/actions/runs/41426848917) 已通过，head 为 `66d23ceb1a5bee7e9cb6362cfc238eb64297f3e6`。实际测试 merge 为 `61979c75f943e7383748c75beed02cf1dde977e5`，全部 86 个变更 blob 与 head 一致。unit/H2：6,098 个用例，跳过 17 个；MySQL 8.4.6：1,242 个用例，无跳过；Hosted：167 个用例，跳过四个；fault：45 个用例，无跳过；Hosted process gates：两个用例，无跳过；O4：59 个用例，无跳过。已完成测试的失败和错误均为零。59 个锁审计用例、六个生产模块 SpotBugs、八个 reactor Checkstyle、Hosted failover 及两个 EventTransport profile 均通过。跳过项不算通过。macOS/Windows 车道编译 reactor 并运行 SDK/Runtime Broker 测试，没有运行 Store 功能套件，该平台缺口继续保留。这些证据验收已合入基线的配置内检查，不验收后续精简改动、真实集群或部署。
+
+精简后续改动从 main `73474ef094ea1c6bb2a95a9a2a33a28b0ec58e9e` 开始，删除 18 个协作类重复默认重载及三个无调用内部方法。facade 入口直接向全参数协作类方法传入原默认值，保留签名、事务属性以及经协作类分派的行为，不转调另一个 facade 重载。消息行直接映射为 `ItemRecord`，通过 `List.copyOf` 保持原分页列表不可变性。可选的 Rows 转发精简继续后置。架构检查通过反例覆盖拒绝 `@Service`/`@Repository` 等 Spring 元注解和任意大小写的 SQL 关键字；分页断言保护列表不可变性。锁审计仅移除已删除的 `beginLifecycle/9` 成员与 `ItemRow.toRecord/0` 豁免，保留 facade 集合、编译成员覆盖和失败关闭反例。
+
+精简改动本地验证的 14 个选定测试类共 232 个用例全部通过，失败、错误、跳过均为零，包含全部 59 个锁审计用例及五个拆分检查用例。八个 reactor Checkstyle 均通过。静态参数替换核对确认 18 条默认路径到达相同的全参数实现，其他 633 个已解析成员正文未变；这些静态检查不是运行时证据。首次末尾空行 Checkstyle 失败已修复，并保留在本次调查记录中。后续源码编辑仅调整注释及调用换行，由最终 Checkstyle 和默认路径核对覆盖。新版本的完整 verify、SpotBugs、真实 MySQL、Hosted/fault 和 full gate 仍待 CI；Store 专项 macOS/Windows 功能资格仍未覆盖。本次精简是 #16090 合入后用户单独选择的新改动，使用自己的共享 600 秒本地预算；原 PR 账本和证据保持原状，不作为新输入的验收证明。
+
+各已实现阶段的验收需覆盖 tenant/actor 隔离、游标语义和批量查询次数；含 definition/skills/worktree 的准入/重放；序号/去重/投影缺口/撤回/replay floor；提交后通知及回滚/重放不通知；租约 generation/token/到期及接受结果未知时不重复派发；journal 原子回滚/重放；资源损坏/读取租约失效/owner read 收尾；publication/snapshot 锁顺序和 CSI 同连接原子性。
+
+SQL/并发路径需要真实 MySQL 证据。CI 承担完整 verify、SpotBugs、完整 MySQL、Hosted/故障及跨平台检查。当前 push 的 fast tier 缺少必需资格项，接受版本的 full Managed Agent gate 才是交付标准。所有未运行项都单独列明。
+
+每片均需完整 diff 连续两轮干净自审及独立评审。最终两个 facade 只保留装配、事务入口和兼容转发，不包含业务 SQL 或状态机。协作者实例依赖无环，公共契约和各路径事务语义保持一致。定向测试通过不等于完整验收。
+
+## 风险与待决事项
+
+已接受的架构方向没有未决产品问题。主要实施风险是隐蔽查询副作用、共享回执/资源校验、lazy 构造回环、事务边界搬移和源码检查盲区。发现意外依赖时，在最小受影响切片内解决，并在改变设计前同步两个语言版本。不把算法、SQL、存储或协议重设计悄然并入搬移 PR。
+
+## 已实现的依赖边界
+
+facade 按原顺序只计算一次配置和 catalog 校验，再把相同值和依赖实例传给协作类的 final 字段。Agent 构造顺序为 Rows → Queries/EventJournal → Policies/Projection → Commands → Admissions/Lifecycle/TurnExecution → ExecutionOperations。Journal 构造顺序为 Rows → Fencing → WriterLifecycle/HistoryQueries/LifecycleAuthorization/ResourceWrites/ResourceReads → Commit。协作类不接收 facade 或构造器回调集合。
+
+共享 Session/Turn 单点读取位于 Rows；Queries 的三个兼容读取入口转发至这些实现。Policies 持有共享准入谓词，Rows 持有它们已有的 key 编码和数据库时间读取。九参数 Session 准入默认方法仍在 facade 上按原样转发到接口默认实现，保留虚分派和事务边界。资源行校验与对象 IO、租约、隔离分别保留。Commit 在原位置调用提取出的生命周期派发授权块，传入已有的调用内资源 reader。
+
+Session 构造现在确定原 setter 涉及的全部九个引用。Spring 必需依赖仍必需；standalone 构造保留原 null/in-process/unbound 默认值。生命周期双依赖任一缺失时，两者均不启用。CSI 仅接受同数据源 JDBC runtime binding repository。维护入口与夹具在创建下游消费者前传入依赖；实际 Spring 工厂构造另有覆盖。
+
+锁检查保留 facade 入口集合，并按 owner/name/arity 钉住删除未使用的 `beginLifecycle/9` 后剩余的 23 个已迁移 private helper 重载。协作类与完整源文件族一起分析，同时逐文件保留显式 SQL 归属边界集合。编译成员覆盖、不可解析接收者的拒绝规则和原有反例仍为必需。下文原行号清单指记录的基线，不指迁移后位置。
+
+## Agent 入口清单
+
+源码：`packages/managed-agent-server/persistence/src/main/java/com/alibaba/qwen/code/managedagent/persistence/ManagedAgentStore.java`。
+
+事务图例：**T** = 保留原始普通 `@Transactional`（默认 REQUIRED、DEFAULT 隔离级别、readOnly false），facade 类保留 `@Qualifier("managedAgentTransactionManager")`；**M** = 在上述基础上显式使用 MANDATORY；**RR** = 显式 transactionManager `managedAgentTransactionManager`、readOnly true、REPEATABLE_READ；**N** = 当前入口没有声明式事务。N 不代表只读，也不授权新增事务。worktree 行另行标明其现有的验证/隔离事务。
+
+所有重载均按源码行号列出。两个构造器保留为 facade 装配；public static `readBinding` 继续在 facade 提供，可转发到行组件。下列生产调用者已按实际接收者声明核对，并单独检查了 CSI 本地 `var` 构造路径；未发现调用的入口明确注明，不意味着可以删除该方法。即使生产代码当前未调用某个兼容入口，测试仍是其消费者。

+| `readBinding` (7569) | N    | WorkspaceFileStore, WorkspaceMigrationMain, WorkspaceMigrationStore |
+
+清单覆盖 **136 个不同入口名 / 153 个声明**，包括两个包可见的 CSI 桥接方法和一个 public static 映射器，不包括两个构造器。
+
+### worktree 展示路径的决定与副作用
+
+worktree 展示入口不是纯读取。`findSessionWorktree` / `findSessionWorktrees` 调用 `SessionWorktreeStore.descriptor(s)`（107-145），`listSessions` 在批量分页 SQL 后调用 `descriptors`（4645）。`verifiedDescriptor`（112-120）验证文件系统身份并读取当前分支；遇到 `ManagedAgentException` 时调用 `blockIdentity`（368-378），后者通过已有的 `TransactionTemplate` 和 `PROPAGATION_REQUIRES_NEW` 将 READY 改为 BLOCKED 并增加 revision。该独立事务特意保证调用方准入失败回滚后，隔离结果仍然保留。最终决定：首个 A1 纯查询切片排除这三个入口名，保留其 facade 原实现直到 A6。A6 将它们迁入既定 AgentSessionQueries 组件，作为明确带副作用的兼容展示路径，复用 SessionWorktreeStore 验证/隔离及其现有事务。不得添加 readOnly、跳过验证、复制隔离代码、删除现有事务，也不增加另一层 worktree 包装。
+
+策略/执行准入也会通过 `requireCwdChangeRegistryFacts`（3894）进入同一条 worktree 验证路径：先执行 `SessionWorktreeStore.requireReady`，再执行 `hasExecutionRegistryFacts`。必须保留 worktree 验证先于 creator/binding 事实检查的顺序，包括持久化隔离语义。
+
+### 事务与桥接例外
+
+- `findWorkspaceCreateReplay`（555）没有事务声明；`replayWorkspaceSessionCommand`（570）带普通 `@Transactional`。二者都会重新检查重放摘要、internal-team-lead 身份、workspace 绑定和当前读取权限。不得统一这两种事务模式。
+- `insertCsiSessionCommand`（582）为包可见方法，没有事务注解，显式要求活动事务并拒绝 journal event transport。`requireCsiRequest`（633）保留相同的 transport 隔离，锁定 Session 和 runtime-request key，并验证 CSI profile/request 身份。调用方 `WorkspaceCsiSessionCommands.create`（19-47）拒绝环境事务，创建新的 10 秒 TransactionTemplate，检查原始物理事务连接，先锁 placement 再锁 retention，验证 registration，随后在该连接上调用两个 Store 桥接入口。此调用方使用 standalone 的 `var sessions = new ManagedAgentStore(...)` 构造路径。
+- `requireCsiRequest` 也由 `WorkspaceCsiRuntimeAccess.request`（183-190）调用；该调用方原有的 continuation/retention 锁行为全部保留。保留 facade 方法的包可见性和七参数 standalone 构造器。
+- `readBinding`（7569）是 public static 方法，由 `WorkspaceMigrationMain`、`WorkspaceMigrationStore` 和 `WorkspaceFileStore` 直接使用；实际映射迁入行组件后，仍需保留 facade 转发入口。
+- `requireMcpSettingsCommit`（1215）和 `requireConfigurationCommit`（1266）使用 MANDATORY。`requireContextCompressionCommit`（3200）没有注解；它在 `ManagedExtensionRecordStore` 的已有提交流程中被调用，不得额外增加 MANDATORY/REQUIRES_NEW 包装。
+- `findMessagePage` 重载（5234/5242）显式使用 managedAgentTransactionManager、readOnly true 和 REPEATABLE_READ。普通 Query 入口没有注解，应继续保持。
+- `deliverableRenames`（1933）是事务内的修改型扫描：先停放过期的 SUBMITTED claim、重置过期的 PREPARING claim，再选择待处理工作。`markRenameSubmitted`（1979）是没有声明式事务的带条件写入。二者均归 Commands，并保留该差异。
+- `contextCompressionState`（3005）调用 `ensureCompactionProjection`（3066）；缺少投影时，通过 DataSourceTransactionManager 创建默认 TransactionTemplate 并重放 journal 行。批量方法 `contextCompressionStates`（3020）可能回落到此写路径，并标记不可用状态。二者归 A8，保留同一程序式事务，不归 A1。
+- `publishAfterCommit`（7489）仅在事务同步提交后发布；没有同步上下文时立即发布。空事件不执行任何操作。EventJournal 提取必须保留 standalone 回退行为，不得增加重放或回滚通知。
+
+### 实际锁路径（不统一为一个全局顺序）
+
+- 行 helper `requireSessionForUpdate`（7061/7066）先锁 PUBLIC Session 行，仅在取得该锁后才读取并锁定对应 event-stream 计数器。列表映射器与严格单 Session 映射器对缺少 stream 的处理不同。需要同时锁二者的路径随后通过 `requireTurnForUpdate`（7106）锁 Turn；提取后保留其 NOT_FOUND 映射。
+- 许多准入、修改和策略入口首先执行 `WorkspaceMigrationAdmission.lockTenant`，然后按路径依次处理 Session/stream、Turn/receipt/operation。MCP/extension 的 idle 复核（1340）专门按此顺序进行新鲜加锁读取：Session plan -> 活动 Turn -> 未结算 child-run record -> requested action records -> 活动 operation/rename/receipt。已有 journal 快照是这些读取不能改成普通一致性读取的原因。
+- 生命周期准入 `beginLifecycle`（2695）先锁 migration tenant，按条件锁 retention tenant，再锁 Session/stream；保留失败操作的重放/恢复、状态授权和 idle journal 检查，按原顺序写 operation/fence/head 及事件。`completeOperation`（4143）先执行 legacy CSI guard，再按条件锁 placement 和 bounded retention，随后根据生命周期协议在 Session 之前或之后加 deletion 锁，最后处理 operation claim。不得统一其分支顺序。
+- `ManagedLegacySessionGuard.requireLegacyMutation` 本身通过 `ManagedSessionStore.namedRootDeadlock` 进行使用索引的 CSI root 加锁读取，查询超时为 10 秒。一些 Turn lease 路径采用此 guard 加带条件 UPDATE，准入/终态路径则取得完整 Session/stream 锁后再处理 Turn。保留差异；通用的行 helper 事务或锁会改变语义。
+- 物化和 replay-floor 推进在检查 Turn 证据或更新 coverage 之前先锁 Session/stream。撤回修复 `rebuildTurnText`（6172）只在外层 Turn 工作流已经取得原有 owner/epoch 锁之后，才锁 stream coverage 和 message 行。
+
+### A1 依赖闭包与边界
+
+A1 普通查询子集需要 JdbcTemplate、已配置的 ObjectMapper、HarnessRules（用于审批规则解码）、构造时固定的 modelCatalog 快照及 Session/Turn 映射器。WorktreeFiles 和三个 worktree 展示入口推迟到 A6 -> AgentSessionQueries 交付。共享行职责包括 `readSession`、sessionMapper/sessionListMapper、turnMapper/turnSummaryMapper、readBinding、nullable/additive 列 helper、StreamCounters 和已有的加锁 Session/Turn 读取器；各项只在首次实际需要时迁移，保留严格读取与列表读取的 stream 差异及全部 schema projection。JSON 解码仅在具体行映射器确实需要时共享，不引入通用 Support/Context 对象。
+
+`findLatestTurns` 按最后一个 turn.accepted 事件选择，而非最新 gmt_create。A6 迁移 `listSessions` 时，必须保留 tenant/actor 授权、archive/title/cursor 过滤、limit+1 语义、批量 worktree 元数据及验证/隔离；查询次数、顺序和字节表示不变。`findSessionById` 是运行时解析已有的跨 tenant 查询，不得擅自增加 tenant 过滤，也不得将其暴露为新的 HTTP 操作。
+
+单点读取和展示视图可以归 Queries；操作任务扫描跟随其状态机（rename -> Commands、materialization/replay floor -> Projection、compression/task cancel/parked -> ExecutionOperations、lifecycle dispatch -> LifecycleOperations、Turn dispatch/recovery -> TurnExecution）。策略、命令和生命周期共享的只读 Session busy 谓词，应在首次迁移时确定唯一的窄职责持有者，不得为了复用它们而让组件回调 facade。
+
+### 后续切片的具体单向协作边界
+
+- A2 EventJournal 持有 appendEvent/appendEvents、event identity/source-key 处理、eventMapper 和提交后发布；可以依赖 Rows，不依赖工作流组件。它不执行同步消息物化。
+- A3 MessageProjection 持有投影扫描、物化、replay-floor 状态及 `rebuildTurnText` 修复 helper。事件读取依赖单向指向 EventJournal/Rows。public `retractContinuationOutput`（6009）和两个 `retractHarnessTurnOutput` 重载（6079/6087）仍是 A9 工作流入口：owner/lease/epoch 检查以及 event/identity 删除先于 A3 修复，并处于同一 facade 事务。不得给 Projection 添加指向 TurnExecution 或 facade 的回调。
+- A4 策略事务拥有现有的 actor 作用域 SET_MODEL/SET_APPROVAL 重放协议，直接使用 ManagedReceipts（4790 起、4954 起）。它们不调用通用 insertCommand/settleTurnCommand。保留这些作用域和原有 result JSON，不将其重写到新的通用 receipt 流程。A4 可以使用 Queries/Rows/EventJournal 和既有 definitions/skills；后续 Commands/Admissions 单向使用策略检查。
+- A5 Commands 持有共同的 `insertCommand`（7156/7163/7170）、`settleTurnCommands`（2477）、`settleTurnCommand`（2532）、Turn command operation 插入（2416）、命令重放和回执。A9 的 recordAdmission/recordRecoveryAdmission/recordHarnessEvents 和终态路径调用此结算边界。A8 接受结果对账必须使用相同的命令/rename 结算语义；Commands 不反向回调 A8/A9。
+- A6 Admissions 依赖下层 policy/command/event/row 组件和既有 definitions/skills/worktree 组件。保留先重放、再进行新准入解析的时点，以及 creator/child 作用域、definition 固定和回滚行为。
+- A7 LifecycleOperations 持有 operation 单点读取、重放、claim/lease/retry/completion 和 operation 映射器。当前共享 API 由 SessionLifecycleCoordinator、ActionResponseCoordinator 和 TaskCancelCoordinator 使用；facade 路由保持不变。A8 按需调用 A7 的 operation 查询及共同 claim 原语，例如 claimContextCompression（3186）完成专用 CAS 后读取 findOperation；requireContextCompressionCommit（3200）通过同一查询检查操作。协调器已经负责选择通用 completion 或专用 cwd/task-cancel 结算；A7 不得变成调用 A8/A9 的派发器。
+- A8 ExecutionOperations 持有专用 cwd/compaction/task-cancel/unknown-acceptance 状态机和对应扫描，向下依赖 Rows/Queries/Policies/Commands/EventJournal 及 A7 共同 operation 原语。通用 claim/retry 不接收用于专用结果处理的回调。
+- A9 TurnExecution 需要 Rows/Queries、共同 Commands 结算、EventJournal 和 Projection 修复。不能仅因协调器另行调用生命周期 API 就让它依赖 LifecycleOperations，应保留两者分离，避免形成环。
+- 实例构造无环是每次提取的显式验收项，不能仅凭这些职责标签宣称已证明。尤其是 hasOpenOperation/hasOpenExecutionOperation/hasPendingRenameDelivery 等共享谓词和已有 schema key 编码器，不得形成 Policies -> Commands -> Policies 或 Commands -> Lifecycle -> Commands 环。应迁移真实依赖闭包，并在适当位置直接使用现有 schema/receipt helper。无需构造器函数集合、facade 回调或可变 setter。
+
+## Journal 入口清单
+
+基线：`e3c7a6d7efc6df6c58ffa8ddd9c42dbb0e1784c4`（2026-11-02）。下文 `M:<line>` 指 `packages/managed-agent-server/persistence/src/main/java/com/alibaba/qwen/code/managedagent/persistence/ManagedSessionStore.java`，共 3931 行。同包文件简称均指该 persistence 目录；Controller 位于 server，Hosted connector 位于 adapters。本清单只定义迁移边界，不代表后续切片已实现或通过验收。
+
+### 1. 结论与边界
+
+- 实现公开业务方法共 27 个签名、22 个名称，全部来自现有 contracts `repository.ManagedSessionStore`。构造器 3 个，装配 setter 8 个、引用 9 个；另有包内方法 17 个、包内 record 2 个、锁等待常量 1 个。下面全部列出。
+- 该 Store 没有 `MANDATORY` 方法。不能把整体方案提到的 `MANDATORY` 错填到 Journal 入口；Journal 的显式特殊事务是两个 `READ_COMMITTED` history 查询和 `NOT_SUPPORTED` 的 initial-journal 检查，外加无声明式事务的资源读取及包内桥接。
+- 新增内部对象不要调用 facade。B1 所需的资源行完整性检查、activation 行映射随首次实际使用进入 `JournalStoreRows`，因此 B1 不需要等待 B3/B5 或回调 facade。对象读取、lease、更新验证时间和 quarantine 均不进入 Rows。
+- 公开业务接口、既有包内入口、`PublicationWriter`、`TerminalCandidate`、静态锁工具与常量继续从 facade 提供；内部 helper 的包可见化只为显式类型依赖，不能新增通用 Context/Support。
+- 锁顺序按路径保留：普通 heartbeat 不获取 tenant guard，CSI continuation 先锁 root 再获取 placement/retention；publication/snapshot 又有自身先行 legacy guard/probe 和调用者锁。不要把这些路径概括成一个强制全局顺序。
+
+### 2. 事务图例
+
+`T`：原方法 `@Transactional`；manager 由类上 `@Qualifier("managedAgentTransactionManager")`（M:82）保持现有解析，注解未指定显式 manager；传播 `REQUIRED`，隔离 `DEFAULT`，`readOnly=false`，默认 timeout/rollback。两个 overload 的注解分别保留，原 self-call 不产生额外代理边界。
+
+`RO`：同一 manager，`REQUIRED` / `DEFAULT` / `readOnly=true`。
+
+`RC`：同一 manager，`REQUIRED` / `READ_COMMITTED` / `readOnly=true`。内部调用 `restore` 目前是 self-call，不能迁移成额外事务。
+
+`NS`：同一 manager，`NOT_SUPPORTED` / `DEFAULT` / `readOnly=true`；挂起调用者事务，自己不创建事务。
+
+`N`：无声明式事务；不得因为提取而新增代理或注解。是否在事务内取决于现有调用者。特别是 standalone 构造器从来不会自动建立 Spring 方法事务。
+
+`P`：`N` 外壳，程序式 owner-read 流程，见第 6 节。
+
+以下锁轨迹记录原有顺序及分支，省略重复取得同一已持有锁，不表示可以删除这些重复调用。`P`（锁列内）= placement tenant guard；`Tg`= output-publication retention tenant guard；`R`= session root；`H`= managed-session head；`D`= harness drain head；`C`= CSI binding/slot/retirement/progress 原连接锁闭包。所有 bounded tenant 等待继续 5 秒，namedRootDeadlock 仅映射其现有死锁集合。

+
+以下构造器及八个 setter 原本均无声明式事务（N）。已有 3 个构造器 M:177/181/187：`(JdbcTemplate)` → 新建 extensionRecords；`(JdbcTemplate, extensionRecords)` → actions=null；Spring 当前 `(qualified JdbcTemplate, extensionRecords, actions)` 三者 required。三个构造链创建同一个 DataSourceTransactionManager，分别给 ToolPublicationRetentionStore 和 ownerReads（timeout=10）；保留这两个原程序式事务对象的配置，不把它们换成新增 Spring Bean 或全局事务 manager 参数。
+
+生产手工调用者只有两个：`server/.../maintenance/WorkspaceCsiRuntimeMain:106–107`（裸构造 + 同 datasource CSI bindings）；`WorkspaceCsiWorkerAckMain:53–54`（裸构造 + SdkHarnessRules）。两者使用场景和默认值不同，不能用一个有额外 enabled 依赖的统一 fixture 替代。
+
+手工测试的中心路径是 `VerificationFixtures.configure(ManagedSessionStore)` :40–46，目前只赋 HarnessRules / StorageReadPolicy。B0 应像 Agent wiring 那样改成明确构造工厂，避免 final 字段反射、先造后重建及 setter 变名。当前构造调用扫描覆盖 52 文件、150 处（2 处生产、148 处 verification），另有 11 文件、16 处显式 setter 调用。B0 迁移逐点核对构造参数、原 setter 条件及 fixture 创建顺序；实施时刷新清单，扫描结果归零只能证明旧装配调用已移除，不能代替行为验证。
+
+扫描当前源文件未发现显式返回 ManagedSessionStore 的 `@Bean` 工厂；有 `ToolPublicationAsyncVerificationTest:317` 的 `.withBean(ManagedSessionStore.class, () -> fixture.sessions)` 路径，其 context 同时提供 HarnessRules、StorageReadPolicy、credentials、bindings 和对象存储。不能依赖 bean postprocessing 继续补已移除 setter，应迁移其已构造 fixture；B0 新增 @Bean 工厂回归验证，避免重演 #16061 漏洞。
+
+依赖图审查：ManagedToolResultStore:40 依赖 EventProjectionStore（Agent facade），WorkspaceExecutionStore:38 依赖 jdbc/transactionManager/WorkspaceStorageGuard/settings；LiteTopicEventTransport:45 只依赖 producer/provider/topic。没有理由为 B0 增加新的 lazy 回环；Agent→records、skills→records 的既有 lazy 边仍原样保留。Spring constructor injection 的 full-context、事务代理和实际工厂测试仍必需。
+
+### 6. 资源读取的实际副作用与事务
+
+#### ordinary / snapshot
+
+M:1930 共享实现先做 scope/credential/resource id/head/read grant；readGrant 自己查 retention live 和 DB now。`outputRetention.read`（ToolPublicationRetentionStore:379）用其现有 `TransactionTemplate`（默认 REQUIRED、DEFAULT、readOnly=false）执行 Tg→R→H 的 `lockGenericSession`，再插入 120 秒 `ma_read_lease`。这会加入既有环境事务；外层方法没有 NOT_SUPPORTED，不能新增。
+
+ordinary 的 findResource `lock=true`，然后 verifyStoredResource，再写 last_verified_at（M:1953），TOOL_PUBLICATION 时读取 object stream；digest/length 错会 quarantine capture/resource。snapshot 的 findResource `lock=false`、不更新 verified、不 quarantine，但 retention lease 仍会插入、按需续期、检查和关闭。两者不是只读组件。`verifyStoredResource` 本身不做这些副作用，见第 8 节。
+
+snapshot 调用者 `ManagedNativeJournalSnapshots:56–61` 既有 isolated template 为 REQUIRES_NEW + READ_COMMITTED；:89 admission/basis、:92 build、:94 lease close、:520 resource read 都沿用该模板。**必须保留这里已经存在的 REQUIRES_NEW**；“不引入 REQUIRES_NEW”只禁止新增，不能删除或复制到新组件。
+
+#### owner
+
+M:1978 同时拒绝 `isActualTransactionActive()` 或已绑定 jdbc datasource 的 resource。非 CSI（M:1995）仍回退 ordinary read。CSI 路径：
+
+1. ownerReads template（M:197–200；同 datasource manager、REQUIRED/DEFAULT/readOnly=false、timeout 10 秒）开启 admission。lockCsiContinuation → original admission 或 DRAINING checkpoint continuation → R/H → read grant → resource metadata FOR UPDATE。校验 inline-only；生成 identity evidence → CSI/read-lease复核 → INSERT `CSI_RESOURCE_READ` OPEN receipt → 再复核 → INSERT ma_read_lease（generation=0）→保存回执。
+2. 退出事务后 `fetchNativeResource` M:2172 使用 DataSource.getConnection() 自己取新连接，仅 SELECT 完整 inline bytes、statement timeout=10。这里才是独立读取阶段，不能持有 admission 事务或复用其物理连接。
+3. `finishNativeRead` M:2199 再开 ownerReads 短事务：重锁 continuation/original→R/H→read receipt FOR UPDATE；身份/receipt变化直接拒绝。fetch 未知异常时记录 UNKNOWN / jdbc_fetch_unknown，原路径不删除 lease；正常返回时检查 read lease FOR UPDATE、metadata FOR UPDATE、row bytes/hash，复核 CSI/read grant，更新 verified，记录 RETURNED（verified 或具体拒绝码），最后复核后删 lease。某些早期 fencing 异常仍回滚而不强行结算，不能“优化”成 finally 删除。
+4. fetch 的 RuntimeException/Error 路径尝试收尾，收尾异常作为 suppressed，原异常继续抛。不能把 owner IO 包成大事务，不能把多次 current-time/read-grant 合并成一次。
+
+### 7. Commit 原子性、CSI 复核和通知
+
+普通/lifecycle commit（M:1118–1459）完整保持一个入口事务。command replay（M:1176–1214）发生在新 resource/projection 写入之前；CSI replay 同样先核验当前 writer、activation replay 和 current time，ordinary replay 仍拒绝 v2 lifecycle claim。duplicate 路径不发事件。
+
+新 commit 先 validateHead / generation / lease，再在需要时对 native `commitFileHistory`/`toolIntent`/`commitCheckpoint` 做 preflight，并重新读 DB time 检验 writer（M:1228–1245）。`commitResources` M:2809 每个 resource 在查 existing 之后、写资源之前执行传入 writeFence；这是已有调用内 callback，可原样保留，禁止把它改成构造器函数集合。
+
+随后同事务完成 declared-resource census、checkpoint/history/hosted closure 校验、HostedCleanupReferences、lifecycle dispatch authorization（M:1313；用成对 execution/session 依赖）、extensionRecords.apply/applyNative、CSI acceptCommit + 再次 writer 检查（M:1343–1367）、actions.apply。journal INSERT 前 requireCsiWriterCurrent（M:1378），head UPDATE 前又 requireCsiWriterCurrent（M:1421），继续 capture tool result events、ManagedUserMessageStore.capture。不能把 resource/projection/journal/head 任一部分分成独立提交。
+
+`publishJournalAfterCommit` M:1466 只由新 commit 尾部 M:1455 调用。transport null 不做事；无 synchronization（standalone）立即 publishCommitted；有 synchronization 注册 afterCommit。rollback 不通知，replay 不通知。CSI continuation/terminal 明确 `requireCsiJournalIsolation`（M:3245）拒绝 transport，因此 terminal 分支没有通知；不要为了统一 commit 加上通知。
+
+CSI terminal 三个桥接方法使用 `WorkspaceCsiApplicationStore.tx` :402–410 创建的既有 10 秒事务和该事务物理连接的 bounded proxy。authority 持有的 connection identity、`DataSourceUtils.getTargetConnection` 和 `isConnectionTransactional` 不可替换为新连接、仅 same URL 判断或单独 helper transaction。preflight 还检查同 datasource JdbcRuntimeBindingRepository。commitCsiTerminal 在冻结字节比较后再次 preflight，每 resource 执行 authority time + writer fence，journal INSERT 前再 fence，head SEALED CAS 前再 fence，返回前再 authority time。`TerminalCandidate` 中 request/proof/token hash 原样保留。
+
+### 8. 共享闭包与单向依赖
+
+`JournalStoreRows` 的允许闭包限于原来的行访问、映射、读取时必要的完整性验证、固定键/字节约束，以及下表显式列出的窄行初始化。它不是纯只读组件，也不能扩展成通用业务 Support：

+# Activity view
+
+[English](activity-view.md) | [简体中文](activity-view.zh-CN.md)
+
+## Problem and evidence
+
+The sidebar lists projects and conversations but offers no single queue for
+approval, input, errors, unread updates and running work. Completion dots are
+currently ephemeral. The reference desktop application implements an activity
+snapshot rather than continuously sorting a filtered list. Its bundled code
+was decompiled and inspected alongside the supplied report and screenshots; it is behavioral
+reference material, not a dependency or source to copy.
+
+## Scope and decisions
+
+Implement a complete activity mode for the Web Shell's daemon workspace
+conversations. Respect the existing host, locked-workspace and trust boundaries.
+The activity directory follows the selected daemon host; it does not aggregate
+other hosts or standalone conversations without a workspace. Managed-agent and
+live-voice surfaces keep their own navigation. Unsupported sources must not be
+silently treated as workspace conversations. Qwen has no
+equivalent of ChatGPT's account history or explicit silent-heartbeat flag; do
+not invent those sources or suppress ordinary background work.
+
+Activity is an alternative mode of the existing conversation surface, not an
+additional list beside it. While open, it replaces the ordinary workspace
+navigation, session search and conversation groups in that surface, including
+the rail layout's Home column. The top-level New session action remains outside
+that surface and stays available when enabled by the host. Close activity with
+the bell or Cmd/Ctrl+Alt+U to restore ordinary navigation; Escape also closes it
+when a dialog or menu does not own that key.
+
+The entry requires the daemon's existing `session_organization` capability,
+the default conversation surface (no host-supplied `sessionContent`), and no
+special section view. There is no additional read-state capability requirement.
+Without these conditions the activity entry and shortcut are unavailable and
+the existing navigation remains in use.
+
+Use the existing directory, live-state feed, transcript page reads and archive
+APIs. No new directory database, model-generated summaries or per-row polling.
+Reuse the sidebar's existing in-memory `completedUnreadIds` for unread state.
+A conversation becomes unread when the page observes its running-to-finished
+transition while it is not the current conversation. Activity rows and the
+existing blue dots share this state; historical conversations are not initially
+unread merely because they lack a read record. Do not add backend read fields,
+capabilities or write requests. Refreshing or remounting the sidebar clears the
+record, completions while the page is closed cannot be reconstructed, and
+separate tabs or clients do not synchronize reads. These are intentional limits
+of preserving the existing completion-dot semantics. Preview reads do not
+change unread state.
+
+## Comparison with the earlier persisted-read design
+
+The current design preserves the existing completion-dot behavior. It reuses
+the daemon's existing organization capabilities and introduces no read-state
+backend version gate. Marking read is a local state update, so it has no receipt
+request failures, retries or cross-client synchronization races. Its limits
+are deliberate: refresh loses unread records, offline completions cannot be
+reconstructed, and each tab or client has independent read state.
+
+The earlier design added `lastReadActivityAt` and required the new
+`session_activity_read_state` capability and an upgraded daemon. It could retain
+read state across reloads and share it through directory refresh. It used the
+observed `updatedAt`, with monotonic writes to prevent older requests from
+overwriting newer acknowledgements. Those guards did not make a session update
+equivalent to a completed assistant turn, and persistence alone did not recover
+every offline completion. Treating historical conversations with no receipt as
+unread also changed the old behavior undesirably. Receipt failures, retries and
+late responses added asynchronous state that this revision removes.
+
+The retained optional `hasTurnError` live-state field is separate from unread
+state. Older daemons can still support activity through existing capabilities,
+but without this field error presentation is best effort: an error may be absent
+or remain stale until other session data refreshes. A future persisted design
+could improve continuity if it defines completion or turn identities, migration
+of unknown historical read state, and whether read ownership belongs to a user
+or a shared daemon. Those decisions are outside this revision.
+
+## Interaction and state
+
+- A bell and Cmd/Ctrl+Alt+U toggle activity. Escape closes it. The bell indicates
+  unread or actionable states, not running work alone.
+  Its selected state uses the existing theme blue with a faint blue background,
+  consistently in the expanded sidebar and navigation rail. Both entries use a
+  pointer cursor in their selected and unselected states.
+- The list starts with its first category, without a separate Activity heading.
+  Exactly one options trigger belongs to the first displayed category: Priority
+  when enabled, otherwise Pinned or the first recent date. An empty list uses a
+  Today heading so the options remain reachable. The options trigger reuses the
+  existing workspace overflow button, vertical ellipsis, right inset and
+  standard auto-width dropdown rather than activity-specific menu styling.
+  Category headings use the normal sidebar's spacing, typography and controls.
+  Activity participates in the existing session-list layout without an extra
+  padded container; groups reuse the normal pinned-session list so headings,
+  row titles, status indicators and action buttons align with normal mode.
+  Expanded empty categories use that same list container and bottom spacing;
+  the priority empty-state message is rendered inside it.
+  Pinned shares its expanded
+  state and chevron interaction with the normal sidebar. Priority also has a
+  collapse toggle, local to the open activity view; date headings remain static.
+  Collapsed category rows are not rendered, do not load previews and consume no
+  visible-row budget. Pinned uses the normal sidebar's ordering, with newly
+  pinned conversations appended rather than placed first.
+- Initial priority order is input/approval/error, unread, running, then idle;
+  ties use descending activity time and stable identity. Child sessions are
+  excluded unless pinned; archived and inaccessible sessions are excluded.
+- Opening records a snapshot. Existing priority entries retain their relative
+  order and remain after reading or completion; new eligible entries merge in.
+  Closing discards the snapshot. Clear read removes settled read entries only.
+- Priority is enabled by default, a separate pinned section and scheduled tasks
+  are disabled. Preferences persist. Reset restores these defaults.
+  The options menu begins with a Display label. When preferences differ from the
+  defaults, an accessible reset icon appears at the right of that label instead
+  of a separate reset menu row. Reset keeps the menu open and recomputes the
+  activity snapshot; it does not change read state or pinned expansion.
+- Recent conversations cover seven local calendar days including today, grouped
+  by date. Priority has no age cutoff. Sections never duplicate identities.
+  A shared budget starts at ten and expands by ten.
+- Rows use the normal sidebar's `renderSessionRow` directly, preserving its
+  selection, keyboard handling, status indicators, inline actions, context menu,
+  rename, pin and archive behavior with the same capability checks. There is no
+  activity-specific row layout, styling, idle dot or always-visible workspace
+  suffix. The existing hover details popover shows time, workspace and other
+  available context, including branch, pull requests and session identity.
+  Assistant previews are capped at 600 Unicode code points and use the normal
+  row's existing snippet slot and styles. Visible rows load bounded transcript
+  pages without attaching or starting sessions. Preview failures use the shared
+  notice layout and can be retried; loading and partial failure remain
+  distinguishable from an empty queue.
+- Selecting a conversation clears its existing completion dot through the
+  sidebar's shared state. Mark all read removes the priority section's unread
+  identities from that same in-memory set; it neither clears the snapshot nor
+  changes unrelated conversations. Closing activity discards only its snapshot,
+  not the sidebar's unread set.
+- Bulk archive applies to priority, excluding recent and pinned-only entries.
+  Confirmation explains when running work will stop. The existing atomic
+  close-and-archive API performs the operation; successes disappear, failures
+  remain, and undo restores successful archives without restarting work.
+  Operations are bounded to eight concurrent requests. Navigation leaves an
+  archived current conversation only after confirmed success.
+  Pending operations, result messages and the undo offer belong to the sidebar,
+  so closing and reopening activity does not discard them, including when a
+  request finishes while the view is closed. Changing the host/workspace scope
+  discards this operation state; late results from an earlier scope cannot
+  populate the new scope, even after switching back. List suppression and
+  restoration overlays remain local to the activity view and follow the
+  authoritative directory when it remounts.
+
+## Implementation boundaries
+
+Unread state stays in the existing sidebar component; the activity model accepts
+the derived unread flag and the catalog controller handles directory reads,
+previews and archive operations. Each identity has one completion observer:
+only while activity is open do its covered conversations transfer to the
+activity observer and leave the legacy scans. With activity closed, the existing
+ordinary-sidebar observers retain their visibility and freshness rules. This
+preserves normal collapsed-rail reminders and prevents duplicate observers from
+recreating a completion already marked read.
+Core organization metadata, Bridge summaries
+and daemon organization routes gain no read-state fields. Live-state includes
+turn errors. Existing workspace routes must use resolved runtime storage,
+including failure paths. Web Shell adds an activity model, controller and view
+under `components/sidebar`, reuses shared UI primitives, and integrates the bell
+with the sidebar. The activity view owns grouping, budgets and preview loading;
+the sidebar supplies its existing session renderer, so ordinary row features
+and styling have one implementation. English and Chinese messages remain
+aligned.
+
+## Validation and acceptance
+
+Test ranking, snapshot stability, date boundaries, filtering, identity,
+pagination, first-category menu placement and empty fallback, priority collapse,
+shared pinned collapse state and ordering, collapsed-row budget, normal/activity
+header and row alignment, shared row actions and hover context, reset icon
+visibility and keyboard access, observed
+completion transitions, shared blue-dot/read behavior,
+refresh reset, absence of read-state writes, stale async responses, partial
+failures, archive scope and undo. Verify that activity replaces workspace/search
+navigation, preserves the enabled top-level New session action, and restores the
+ordinary surface through each exit; also verify the `session_organization`
+capability gate. Run a baseline against global `qwen`
+and browser fixtures before implementing, then focused tests, browser E2E,
+build, typecheck and bundle. Read the full diff in two clean audit passes and
+perform an independent review. Test only isolated conversations; never archive
+the user's real reference chats. There are no product decisions awaiting user
+approval; implementation and verification findings may refine this document.
+
+## Related work and visual evidence
+
+Issue [#16020](https://github.com/QwenLM/qwen-code/issues/16020) tracks this
+feature. Existing unread persistence work in
+[#11451](https://github.com/QwenLM/qwen-code/issues/11451) and
+[#12672](https://github.com/QwenLM/qwen-code/pull/12672) remains separate; this
+feature does not resolve offline or reload continuity. The latter proposes
+browser localStorage, not backend receipts, and overlapping sidebar changes
+will need reconciliation if it lands first.
+
+The screenshots below use synthetic daemon fixtures, not personal conversations.

+
+## 问题与证据
+
+侧栏目前展示项目和会话，但缺少统一处理审批、输入、错误、未读更新和运行中任务的
+入口。完成提示点只保存在内存中。参考桌面应用使用活动快照，而不是持续重排的过滤
+列表。已结合交接报告和截图反编译并检查其打包代码；这些材料仅作为行为参考，不作为依赖，
+也不直接复制代码。
+
+## 范围与决策
+
+为 Web Shell 的 daemon 工作区会话实现完整活动模式，遵守已有主机、锁定工作区和
+信任边界。活动目录跟随当前选中的 daemon 主机，不聚合其他主机或无工作区的独立
+会话。Managed-agent 和实时语音保留自身导航。不把不支持的来源偷偷当成工作区
+会话。Qwen 没有 ChatGPT 账号历史或明确的静默心跳标记，因此不虚构这些来源，也不
+隐藏普通后台任务。
+
+活动是既有会话区域的替代模式，不是在旁边增加另一份列表。打开时，它替换该区域中的
+普通工作区导航、会话搜索和会话分组，包括 rail 布局的 Home 列。顶部“新任务”操作
+位于该区域之外，在宿主启用时仍可使用。点击铃铛或按 Cmd/Ctrl+Alt+U 关闭活动后恢复
+普通导航；没有对话框或菜单占用 Escape 时，也可用 Escape 退出。
+
+入口要求 daemon 已有的 `session_organization` 能力、默认会话区域（宿主没有提供
+自定义 `sessionContent`），且当前不是特殊分区视图。不额外要求已读状态能力。
+不满足这些条件时，活动入口及快捷键不可用，继续使用原有导航。
+
+复用既有目录、实时状态、会话记录分页和归档接口，不新增目录数据库、模型摘要或
+逐行轮询。未读状态复用侧栏原有的内存集合 `completedUnreadIds`。页面观察到非当前
+会话从运行中变为结束时，将它记为未读。活动条目和原有蓝点共享这份状态；历史会话
+不会因为没有已读记录而默认未读。不新增后端已读字段、能力声明或写入请求。刷新
+页面或重新挂载侧栏会清空记录，无法还原页面关闭期间的完成情况，不同标签页或客户端
+之间也不同步已读。这些限制是保留原有完成提示点语义的明确选择。预览读取不改变
+未读状态。
+
+## 与此前持久化已读方案的比较
+
+当前方案保留原有完成提示点的行为，复用 daemon 已有的会话组织能力，不新增已读状态
+所需的后端版本门槛。标为已读只更新本地状态，不涉及回执请求失败、重试或跨客户端
+同步竞争。其限制是明确的：刷新后丢失未读记录，无法还原离线期间的完成情况，每个
+标签页或客户端独立维护已读状态。
+
+此前方案增加了 `lastReadActivityAt`，要求新增的 `session_activity_read_state`
+能力及升级后的 daemon。它可以在刷新后保留已读状态，并通过目录刷新共享状态。
+回执使用已观察到的 `updatedAt`，通过单调写入防止旧请求覆盖较新的确认。但这些保护
+并不能让会话更新等同于助手回合完成，单靠持久化也无法恢复所有离线完成事件。将没有
+回执的历史会话视为未读，还不必要地改变了原有行为。回执失败、重试和延迟响应增加了
+异步状态处理，本次修订将这些逻辑移除。
+
+保留的可选实时状态字段 `hasTurnError` 与未读状态无关。旧 daemon 仍可凭已有能力
+支持活动视图，但缺少该字段时错误展示只能尽力提供：错误可能未显示，或直到其他
+会话数据刷新前仍然过期。未来如果重新设计持久化，可以通过明确完成事件或回合身份、
+未知历史已读状态的迁移，以及已读状态属于用户还是共享 daemon，改善跨页面连续性。
+这些决策不在本次修订范围内。
+
+## 交互与状态
+
+- 铃铛和 Cmd/Ctrl+Alt+U 切换活动模式，Escape 关闭。铃铛提示未读或需要处理的状态，
+  单纯运行中不会点亮关注提示。
+  激活时使用既有主题蓝色图标和淡蓝背景，展开侧栏与导航栏入口保持一致。
+  两个入口在激活和未激活时均使用手形指针。
+- 更多入口复用工作区的竖向三点图标、按钮和右侧间距，下拉菜单使用普通菜单的
+  自适应宽度，不定义活动专用的更多菜单样式。
+- 列表直接从首个分类开始，不单独显示固定的“活动”标题。选项按钮只出现一次，位于
+  首个显示分类的标题上：启用优先事项时位于优先事项，否则位于置顶或首个最近日期。
+  空列表使用“今天”标题，确保选项仍可访问。选项按钮复用既有工作区菜单的竖向省略号、
+  右侧缩进和标准自适应宽度下拉菜单，不使用活动专用菜单样式。分类标题沿用普通侧栏
+  的间距、文字样式和控件。活动视图直接参与既有会话列表布局，不增加带内边距的外层
+  容器；分组复用普通置顶会话列表，使标题、行文本、状态标识和操作按钮与普通模式
+  对齐。展开的空分类也使用同一列表容器及底部间距，优先事项的空状态提示放在该容器内。
+  置顶与普通侧栏共享展开状态及箭头交互。优先事项同样支持折叠，其展开状态
+  保留在本次打开的活动视图内；日期标题不折叠。折叠后的分类行不渲染、不加载预览，
+  也不占用可见行预算。置顶沿用普通侧栏的排序，新置顶会话追加在末尾，而非排在最前。
+- 初始优先顺序为输入/审批/错误、未读、运行中、空闲，同级按活动时间降序和稳定身份
+  排序。子会话除非置顶否则排除；归档和无权访问的会话排除。
+- 打开时建立快照，已有优先条目保持相对顺序，阅读或完成后暂留，新符合条件的条目
+  增量合并。关闭清除快照。“清除已读”仅移除已经结束且已读的条目。
+- 默认显示优先事项，不单独显示置顶，不包含定时任务。偏好持久化，可恢复默认。
+  选项菜单顶部显示“显示”标签。偏好偏离默认值时，标签右侧出现具有无障碍名称的
+  重置图标，不再单独占用重置菜单行。重置后菜单保持打开并重新计算活动快照，不改变
+  已读状态或置顶展开状态。
+- 最近会话包含今天在内的七个本地自然日，按日期分组。优先事项不受时间窗口限制。
+  各分区不重复。共享首屏预算为十条，每次增加十条。
+- 会话行直接复用普通侧栏的 `renderSessionRow`，保留相同能力检查下的选择、键盘、
+  状态标识、行内操作、上下文菜单、重命名、置顶和归档行为。不另建活动行布局或
+  样式，不添加空闲状态点，也不常驻显示工作区后缀。时间、工作区和其他可用上下文
+  通过既有悬浮详情展示，包括分支、PR 和会话身份。助手预览最多 600 个 Unicode
+  码点，复用普通行已有的摘要槽位及样式。可见行按需读取有界会话记录页，不附加或
+  启动会话。预览失败复用通用提示布局并支持重试；加载中和部分失败不能伪装成空列表。
+- 选择会话时，通过侧栏共享状态清除原有完成提示点。“全部标为已读”从同一内存集合
+  中移除优先分区的未读身份，不清除快照，也不改变无关会话。关闭活动视图只丢弃
+  活动快照，不清空侧栏的未读集合。
+- 批量归档仅作用于优先事项，不影响最近会话和仅在置顶分区的条目。确认框明确提示
+  运行中的工作将停止，复用现有原子关闭并归档接口。成功项移除，失败项保留，撤销
+  恢复成功归档的会话但不重启任务。最多八个请求并发。当前会话确认归档成功后才
+  导航离开。
+  进行中的操作、结果提示及撤销入口由侧栏持有，因此关闭并重新打开活动不会丢失，
+  请求在关闭期间完成时也如此。切换主机或工作区作用域会丢弃这些操作状态；即使随后
+  切回原作用域，之前请求的延迟结果也不能写入新作用域。列表临时隐藏和恢复覆盖仍
+  属于活动视图本地状态，重新挂载时以实际目录为准。
+
+## 实现边界
+
+未读状态保留在既有侧栏组件中，活动模型接收由其派生的未读标记，目录控制器负责目录
+读取、预览和归档。每个会话身份只有一个完成状态观察器：仅活动打开时，其覆盖的会话
+才交给活动观察器并退出原有扫描。活动关闭时，普通侧栏观察器继续沿用原有可见性与
+数据新鲜度规则，保留正常折叠条提醒，并避免双观察器重新标记已经清除的未读。
+Core 组织元数据、Bridge 摘要和
+daemon 组织修改路由不增加已读
+字段。实时状态补充回合错误。既有工作区路由的所有路径（包括失败）都使用已解析
+运行时的存储。Web Shell 在 `components/sidebar` 下新增活动模型、控制器和视图，
+复用共享 UI 基础组件，并在侧栏接入铃铛。活动视图负责分组、预算和预览加载，侧栏
+提供既有会话行渲染器，使普通行的功能与样式只有一份实现。中英文文案保持一致。
+
+## 验证与验收
+
+覆盖排序、快照稳定性、日期边界、过滤、身份、分页、首分类菜单位置与空态回退、优先
+事项折叠、共享置顶折叠状态与排序、折叠行预算、普通与活动模式的标题及行对齐、共享
+行操作与悬浮上下文、重置图标显示及键盘访问、观察到的
+完成状态转换、蓝点与
+已读行为共享、刷新重置、不发送已读写入、过期异步结果、部分失败、归档范围和撤销。
+验证活动会替换工作区及搜索导航、保留已启用的顶部“新任务”操作，并通过各退出方式
+恢复普通区域；同时验证 `session_organization` 能力门槛。
+实现前对全局 `qwen` 和浏览器夹具记录基线；
+实现后运行针对性测试、浏览器 E2E、build、typecheck 和 bundle。完整 diff 进行两轮
+连续干净自查，并独立审查。仅操作隔离测试会话，不归档用户真实参考聊天。目前没有
+等待用户批准的产品决策；实现和验证结果可以进一步修订本文。

+# Channel Request Owner Approval
+
+[English](channel-request-owner-approval.md) | [简体中文](channel-request-owner-approval.zh-CN.md)
+
+## Problem
+
+Text permission commands currently require shared-session operator privileges
+before locating the request. An admitted user can therefore start a turn and
+receive a tool confirmation they cannot answer, including in a direct message
+using `sessionScope: "single"`. Group request owners encounter the same failure.
+
+## Decision
+
+Allow an admitted sender to use `/approve` (allow once) and `/deny` for their
+own pending request in their current attended turn. This applies to direct and
+group conversations, independently of the `operators` list, including an empty
+list. Ownership of one request does not grant shared-session management rights.
+
+Retain the existing operator requirements for `/approve-always`, approvals of
+another sender's text request, `/cancel`, `/clear`, `/who`, `/status`, `/loop`,
+`/btw`, loop tools, and steering. Existing native-card owner checks remain in
+place. This change does not broaden native-card delegation or persistent grants.
+
+## Implementation and Boundaries
+
+Keep session routing and the shared-session operator predicate unchanged. Record
+the active run ID with a pending permission. For a caller without shared-session
+operator rights, filter lookup candidates to requests whose sender, current
+attended run, chat, and thread match the caller. A missing, cancelled,
+unattended, or superseded run cannot supply owner authority. Apply this filter
+before producing ambiguity lists or permission titles, including explicit IDs.
+
+Operators retain the existing lookup rules and normal conversation admission.
+Named-task selection, native-card ownership, permission options, and settlement
+continue to use the existing paths. Do not infer operators from pairing or
+automatically rewrite configuration.
+
+## Validation and Acceptance
+
+- In `single`, `chat_thread`, and group `thread` sessions, the current request
+  owner can approve once or deny without operator membership.
+- A real privately paired sender can answer their own direct-message request.
+- Another ordinary member cannot answer or list another sender's requests; the
+  denied attempt leaves the request available for its owner.
+- Cross-chat and cross-thread explicit IDs, requests without an attended owner,
+  cancelled turns, and requests belonging to an earlier run are rejected.
+- A non-operator owner cannot gain persistent permission with `/approve-always`
+  in a shared session or clear the shared conversation.
+- Existing operator delegation and native-card request settlement keep working.
+- Run focused and full ChannelBase tests, build, typecheck, and bundle; distinguish
+  local harness checks from live IM acceptance, which requires a deployed build.
+
+## Risks
+
+This intentionally separates request authority from session management: an empty
+`operators` list continues to disable shared-session management and delegation,
+but no longer prevents an attended request owner from approving once or denying.
+The request must use the active run's sender snapshot, rather than the initial
+owner of a `single` session shared across senders.

+# Channel 请求发起者审批
+
+[English](channel-request-owner-approval.md) | [简体中文](channel-request-owner-approval.zh-CN.md)
+
+## 问题
+
+文字权限命令目前在查找请求前就要求共享会话操作员权限。因此，通过准入的用户可以
+发起轮次并收到工具确认，却无法回答，使用 `sessionScope: "single"` 的私聊也会
+遇到此问题。群聊中的请求发起者同样受影响。
+
+## 决策
+
+允许通过准入的发送者对自己当前交互轮次的待审批请求使用 `/approve`（仅允许
+本次）和 `/deny`。该规则覆盖私聊和群聊，不依赖 `operators` 名单，空名单也适用。
+拥有某个请求的审批权，不代表获得共享会话管理权。
+
+`/approve-always`、代答其他发送者的文字请求、`/cancel`、`/clear`、`/who`、
+`/status`、`/loop`、`/btw`、loop 工具及 steer 保留现有操作员权限要求。
+现有原生卡片的发起者校验保持不变，不扩大卡片代审或持久授权权限。
+
+## 实现及边界
+
+保持会话路由和共享会话操作员判定不变。在待审批请求中记录当前 run ID。
+对于没有共享会话操作员权限的调用者，查找时仅保留发送者、当前交互轮次、聊天及
+线程均匹配的请求。缺失、已取消、无人值守或已被替换的轮次不能提供发起者权限。
+在生成歧义列表或显示请求标题之前应用筛选，显式请求 ID 也遵循此规则。
+
+操作员保留现有查找规则，并仍需通过正常会话准入。命名任务选择、原生卡片归属、
+权限选项和请求结算复用已有路径。不从 pairing 推导操作员，也不自动改写配置。
+
+## 验证与验收
+
+- 在 `single`、`chat_thread` 和群聊 `thread` 会话中，当前请求的发起者无需
+  操作员身份即可仅批准本次或拒绝。
+- 真实通过私聊配对的发送者能够回答自己在私聊中触发的请求。
+- 其他普通成员不能回答或列出别人的请求；拒绝代答后，请求仍可由发起者回答。
+- 拒绝跨聊天或线程的显式 ID、没有交互发起者的请求、已取消轮次和旧轮次请求。
+- 共享会话中的非操作员发起者不能通过 `/approve-always` 获取持久权限，也不能
+  清空共享对话。
+- 现有操作员代审和原生卡片请求结算继续正常工作。
+- 运行定向及完整 ChannelBase 测试、构建、类型检查和打包；区分本地测试与需要
+  部署新构建后才能进行的真实 IM 验收。
+
+## 风险
+
+本次有意区分请求审批权和会话管理权：空 `operators` 继续禁用共享会话管理和
+代审，但不再阻止当前交互请求的发起者仅批准本次或拒绝。请求必须使用当前轮次的
+发送者快照，不能使用跨发送者共享的 `single` 会话最初记录的归属。

+# Add a sidebar session to Split View
+
+[English](sidebar-session-split-view.md) | [简体中文](sidebar-session-split-view.zh-CN.md)
+
+## Problem and current behavior
+
+Issue #14775 requests an “Add to Split View” action in a sidebar session's
+context menu. Today users must open Split View from the footer, then use its
+session picker. App owns the pane list; SplitView already supports adding
+sessions, deduplication, and a six-pane limit.
+
+## Proposed changes
+
+- Sidebar adds a dropdown-only `split` action to its default action list,
+  with English and Simplified Chinese labels. It follows the existing action
+  allowlist, screen-size capability, busy state, and workspace eligibility
+  checks. Only default workspace sessions (including legacy sessions without
+  source metadata) offer the action, matching the split session directory.
+  Archived, channel, standalone, Live, unknown, and untrusted sessions do not
+  offer this action.
+- App appends the selected session when Split View is open. When it is
+  closed, the menu opens the selected session alongside the current workspace
+  session when available, without restoring the old pane list. The footer
+  retains its existing behavior of restoring that list.
+  Opening reuses the existing split opener and classification. Additions made
+  while opening is pending are combined within the current classification
+  generation; navigation cancels that pending selection. Appending
+  uses the same synchronous pane update as the existing picker: Sidebar
+  already limits targets to eligible active workspace sessions. This
+  preserves existing panes and unsent attachments. Embedded hosts
+  controlling the pane list receive the existing change callback and retain
+  ownership of applying the change. Pending additions include only IDs the host
+  has already accepted through its controlled props.
+- Repeated sessions are not duplicated. At six panes, adding another session
+  is disabled with the existing limit explanation; existing panes are kept.
+- SplitView reveals a newly added external pane by clearing maximization
+  and making that pane active, matching its existing session picker.
+
+## Design decisions and scope
+
+Keep Sidebar → App → SplitView ownership intact. The menu emits an intent;
+App combines IDs; SplitView renders and manages pane focus. Reuse the
+existing workspace classification, providers, Radix menu, and portal.
+No daemon, SDK, desktop Rust, CSS, keyboard shortcut, transport, or archive
+lifecycle changes are required. The desktop app loads the same Web Shell.
+Existing split transport limitations are outside this feature.
+
+## Affected files
+
+- `packages/web-shell/client/components/sidebar/WebShellSidebar.tsx`
+- `packages/web-shell/client/App.tsx`
+- `packages/web-shell/client/components/SplitView.tsx`
+- `packages/web-shell/client/i18n.tsx`
+- Adjacent component tests and Web Shell browser tests.
+
+## Validation and acceptance criteria
+
+Verify the real menu opens current + selected sessions, appends without
+replacing panes, ignores duplicates, and respects the six-pane limit.
+After leaving a full split, the menu must still open current + selected.
+Verify the new pane is visible after another pane was maximized. Check
+delayed standalone classification, pane identity, and consecutive additions,
+including the first opening, deduplication, capacity, and navigation cancellation.
+Check English/Chinese labels, action allowlists, archived and ineligible sessions,
+trusted secondary workspaces, small screens, controlled embedding, and the
+existing footer/picker behavior.
+
+Run focused unit and browser tests, build, typecheck, bundle, and repeat the
+relevant tests in local Docker Linux. Record baseline and verification
+evidence in `.qwen/e2e-tests/14775/`.
+
+## Open questions
+
+None. Duplicate selection is a no-op; capacity does not evict existing panes.

+# 从侧边栏将会话添加到分屏视图
+
+[English](sidebar-session-split-view.md) | [简体中文](sidebar-session-split-view.zh-CN.md)
+
+## 问题与当前行为
+
+Issue #14775 希望在侧边栏会话菜单中增加“添加到分屏视图”。
+目前用户必须先通过底部入口打开分屏，再使用会话选择器。
+App 持有面板列表；SplitView 已支持添加会话、去重和六个面板的上限。
+
+## 拟议改动
+
+- Sidebar 默认动作列表新增仅在下拉菜单出现的 `split` 动作，
+  提供英文和简体中文文案。沿用现有动作白名单、屏幕大小能力、
+  忙碌状态与工作区资格检查。只允许普通工作区会话（包括缺少来源元数据
+  的旧会话），与分屏会话目录一致。归档、渠道、独立、Live、未知工作区及
+  不可信工作区的会话不提供此动作。
+- App 在分屏打开时追加选中会话；分屏关闭时，菜单打开选中会话，
+  并在当前会话属于工作区时将其一起加入，不恢复旧面板列表。
+  底部入口仍保持恢复旧列表的既有行为。打开时复用现有分屏打开流程与会话分类。
+  等待打开期间的添加操作合并到当前分类代次的选择中；导航离开会取消待处理选择。
+  追加时沿用面板内选择器的同步面板更新：Sidebar 已将目标限制为符合资格
+  的活跃工作区会话，因此可以保持现有面板及未发送附件。
+  对于控制面板列表的嵌入宿主，通过现有变更回调提出请求，
+  仍由宿主决定何时应用变更。等待分类期间只合并宿主已通过受控属性接受的会话 ID。
+- 重复会话不会重复添加。已有六个面板时禁用添加新会话，
+  并显示现有限制说明；保留已有面板。
+- SplitView 收到外部新增面板时退出最大化并激活新面板，
+  与现有会话选择器的行为一致。
+
+## 设计决策与范围
+
+保留 Sidebar → App → SplitView 的职责分工。菜单发送操作意图，
+App 组合会话 ID，SplitView 渲染并管理面板焦点。
+复用已有工作区分类、provider、Radix 菜单及 portal。
+无需修改 daemon、SDK、桌面 Rust、CSS、快捷键、传输机制或归档生命周期。
+桌面端加载同一个 Web Shell。已有分屏传输限制不属于本功能范围。
+
+## 涉及文件
+
+- `packages/web-shell/client/components/sidebar/WebShellSidebar.tsx`
+- `packages/web-shell/client/App.tsx`
+- `packages/web-shell/client/components/SplitView.tsx`
+- `packages/web-shell/client/i18n.tsx`
+- 相邻组件测试和 Web Shell 浏览器测试。
+
+## 验证与验收标准
+
+通过真实菜单验证当前与选中会话一起打开、追加时不替换已有面板、
+重复添加无效以及六面板上限。验证另一面板最大化后新增面板仍可见。
+离开已有六个面板的分屏后，菜单仍应打开当前与选中会话。
+验证独立会话分类延迟、面板身份保持以及连续追加，包括首次打开期间的
+连续添加、去重、容量限制及导航取消。
+检查中英文文案、动作白名单、归档及不符合资格的会话、可信次工作区、
+小屏幕、受控嵌入，以及原有底部入口和选择器行为。
+
+运行定向单元测试和浏览器测试、构建、类型检查、打包，并在本地
+Docker Linux 中重跑相关测试。基线与验证结果保存在
+`.qwen/e2e-tests/14775/`。
+
+## 未决问题
+
+无。重复选择无操作；达到容量上限时不移除已有面板。

Keep actual shares, including an over-reported source above 100%, without silently clamping the displayed number. Keep the bar row's top margin, model-list gap and model-heading bottom margin at zero. All fonts remain fixed during sidebar resizing.

+# Token usage trend and model colors
+
+[English](token-usage-trend.md) | [简体中文](token-usage-trend.zh-CN.md)
+
+## Status and scope
+
+Implemented in two steps:
+
+- **Step 1 (#16108, frontend only):** request success rate, session output speed, a categorical model palette and a per-model share bar.
+- **Step 2 (this change):** per-request timing samples and failure records in core and on the daemon stats route, plus a speed and first-token timeline in Web Shell Token Usage.
+
+This design builds on [Per-model generation timing](model-generation-timing.md) and [Token usage hierarchy](token-usage-hierarchy.md). CLI `/stats` is out of scope.
+
+## Problem
+
+1. Each model showed only its average output speed. A slowdown in the middle of a session, a few slow outliers, and a steady low speed all produced the same number.
+2. The daemon counted failed API calls per model (`api.totalErrors`), but the panel never showed them. A model that kept hitting 429s or timeouts looked healthy.
+3. Models were hard to tell apart. The first two palette colors were both blue (`#4b67ff` / `#4f94e7`, OKLab ΔE 12.3 for normal vision, below the 15 floor). Every share bar faded from the same blue, and the cards had no other color.
+
+## Design
+
+### D1 — Success rate (step 1)
+
+Success rate = `(totalRequests − totalErrors) / totalRequests`, for the session and per model. Every failed attempt counts, retries included, which matches the existing counter. Internal prompts stay included, as in `totalRequests`. A tooltip on the label states this. Rates below 100% never round up to 100%: anything between 99.95% and 100% shows as 99.9%. Status: 100% shows a check, below 100% a warning, below 90% an error. Each status comes with an icon and text, never color alone, and uses the theme's `--success-color`, `--warning-color` and `--error-color`.
+
+### D2 — Model colors (step 1)
+
+Six categorical colors with separate steps for light and dark: blue, orange, aqua, violet, magenta, yellow. Light: `#2a78d6 #eb6834 #1baf7a #6250d6 #e87ba4 #eda100`. Dark: `#3987e5 #d95926 #199e70 #9085e9 #d55181 #c98500`. Adjacent pairs keep OKLab ΔE ≥ 9 under protanopia, deuteranopia and tritanopia, and ≥ 15 for normal vision. A model's slot is the order it was first used, which is the daemon's key order for `models`, not its rank by tokens. A model therefore keeps its color when the ranking changes. The seventh and later models share a neutral gray instead of a generated hue. Color marks identity only: share bar segments, the legend swatch, the card's left strip, and the timeline's dots and lines. All text keeps the text colors.
+
+### D3 — Per-request samples in core (step 2)
+
+`StatsModelMetrics` gains two optional fields, filled only in session buckets that feed the stats route:
+
+- `timingSamples`: one entry per timed, non-internal response, under the same rules as `generation`: `{ at, ttftMs, generationMs, outputTokens, source? }`, oldest first. Only the latest `MAX_TIMING_SAMPLES` (200) are kept.
+- `failures`: `byKind` counts every failed call by HTTP status code, else error type, else `unknown`. `recent` holds the latest `MAX_FAILURE_SAMPLES` (50) as `{ at, kind, source? }`. `byKind` is a null-prototype map, and stays one after snapshot/restore.
+
+`at` comes from the event's `event.timestamp`, which falls back to the current time. Session replay feeds stored `ui_telemetry` events back through `addEvent`, so a resumed session rebuilds its timeline from history. Events recorded before `generation_ms` existed still carry no timing, as before. As with `generation`, neither field is added to `models`, which is also written to managed usage records with closed key sets.
+
+### D4 — Stats route fields (step 2)
+
+`GET /session/:id/stats` copies `timingSamples` (when non-empty) and `failures` into `models[name]`. `ServeSessionStatsModelMetrics` and `DaemonSessionStatsModelMetrics` declare both as optional. Older daemons omit them, and the panel then shows no timeline or spread. A full poll every 2 s carries at most 200 timing and 50 failure entries per model.
+
+### D5 — Speed timeline (step 2)
+
+When any model has samples or failures, a "Speed over time" card appears between the overview and "By model":
+
+- The x-axis is wall-clock time. Each request is a dot in its model's color, and a line traces the median of its five neighbors to show the trend without following every outlier.
+- A toggle switches the y-axis between output speed (tok/s) and first-token latency (s). The chart has one axis at a time. Responses whose generation window is below 100 ms appear in the first-token view only.
+- Failed requests appear as red × marks in a strip under the plot, in both views.
+- Hovering or touching shows the nearest request in a tooltip, with crosshair and highlight: model, time, subagent, speed, first token, output tokens and generation time; for a failure, its kind.
+- With two or more models, a legend doubles as a series toggle. Hiding the last visible series shows all again.
+- The SVG's accessible name summarizes the metric and each visible model's median.
+
+### D6 — Card spread and failure kinds (step 2)
+
+Each model card with at least two rate-measurable samples shows a dot strip of every sample's output speed. It has a p10–p90 band and a p50 tick, on one scale shared by all cards, followed by `p50 · p10–p90 tok/s`. The existing average output speed in the timing grid stays. A model with failures lists them by kind, for example `Failed: 429 ×2 · timeout ×1`, most frequent first.
+
+## Compatibility
+
+- All new fields are optional and additive. Older daemons render as before step 2.
+- The timeline holds the most recent 200 timed responses per model. Older ones still count toward every aggregate.
+- A managed session restored through `restoreSessionModelMetrics` does not get samples back, the same as per-model timing.
+
+## Out of scope
+
+- Separating retries from final failures, and excluding internal prompts from the success rate.
+- Incremental (`since`) polling of samples.
+- Timelines in CLI `/stats`.
+
+## Validation
+
+- **Core:** samples are recorded with event time, subagent source and the 200 cap; untimed, internal and session-less events are skipped; failures are keyed by status code, then error type, then `unknown`, including `__proto__`, and capped at 50 while the counts keep growing; `byKind` stays null-prototype after snapshot/restore.
+- **CLI:** the stats extension method returns `timingSamples` and `failures`, and omits them when empty.
+- **Web Shell unit:** dots per model in each view, the 50 ms window excluded from speed, failure marks, the accessible summary, legend toggling, nearest-point and failure tooltips, card spread quantiles, failure kinds in Chinese, and no timeline without samples.
+- **Web Shell E2E (Chromium):** 1200px/390px, en/zh-CN, light/dark. The timeline renders with the model colors, the tooltip opens on hover and tap, and the ×-mark count matches the failures.

+# Token 消耗趋势与模型颜色
+
+[English](token-usage-trend.md) | [简体中文](token-usage-trend.zh-CN.md)
+
+## 状态与范围
+
+分两步实现：
+
+- **第一步（#16108，只改前端）：** 请求成功率、会话输出速度、模型分类色和按模型的占比条。
+- **第二步（本次改动）：** core 和 daemon stats 路由提供逐次请求的耗时样本和失败记录，Web Shell Token 消耗面板新增输出速度与首 token 时间线。
+
+本设计基于[按模型的生成耗时](model-generation-timing.zh-CN.md)和 [Token 消耗层级](token-usage-hierarchy.zh-CN.md)。CLI `/stats` 不在范围内。
+
+## 问题
+
+1. 每个模型只显示平均输出速度。会话中途变慢、少数几次特别慢、始终偏慢，这三种情况得到的是同一个数字。
+2. daemon 一直按模型统计失败的 API 调用（`api.totalErrors`），但面板从未显示。一个模型反复遇到 429 或超时，看起来也一切正常。
+3. 多个模型很难区分。调色板前两个颜色都是蓝色（`#4b67ff` / `#4f94e7`，色觉正常时 OKLab ΔE 只有 12.3，低于 15 的及格线）。所有占比条都从同一个蓝色开始渐变，卡片上也没有其他颜色。
+
+## 设计
+
+### D1 — 成功率（第一步）
+
+成功率 = `(totalRequests − totalErrors) / totalRequests`，会话整体和每个模型各算一个。每次失败的尝试都计入，包括重试，与现有计数口径一致。内部请求仍然计入，和 `totalRequests` 一致。标签的提示里写明了这一口径。低于 100% 的值不会四舍五入成 100%：介于 99.95% 和 100% 之间的显示为 99.9%。状态：100% 显示 ✓，低于 100% 显示警告，低于 90% 显示错误。每种状态都同时有图标和文字，不只靠颜色区分，颜色使用主题的 `--success-color`、`--warning-color` 和 `--error-color`。
+
+### D2 — 模型颜色（第一步）
+
+6 个分类色，浅色和深色主题各有一套：蓝、橙、青绿、紫、粉、黄。浅色：`#2a78d6 #eb6834 #1baf7a #6250d6 #e87ba4 #eda100`；深色：`#3987e5 #d95926 #199e70 #9085e9 #d55181 #c98500`。相邻两色在红色盲、绿色盲和蓝色盲下 OKLab ΔE ≥ 9，色觉正常时 ≥ 15。模型的颜色按首次使用的顺序分配（即 daemon 返回的 `models` 键顺序），不按 token 排名分配，因此排名变化时颜色不变。第 7 个及以后的模型共用一个中性灰色，不再生成新颜色。颜色只用来标识模型，出现在占比条分段、图例色块、卡片左侧色条，以及时间线的点和线上。所有文字仍使用正文颜色。
+
+### D3 — core 中的逐次请求样本（第二步）
+
+`StatsModelMetrics` 新增两个可选字段，只写入供 stats 路由使用的会话桶：
+
+- `timingSamples`：每次有计时数据、非内部的响应记一条，规则与 `generation` 相同：`{ at, ttftMs, generationMs, outputTokens, source? }`，按时间从旧到新，只保留最近 `MAX_TIMING_SAMPLES`（200）条。
+- `failures`：`byKind` 按 HTTP 状态码统计所有失败调用，没有状态码时用错误类型，都没有时记为 `unknown`。`recent` 保留最近 `MAX_FAILURE_SAMPLES`（50）条，格式为 `{ at, kind, source? }`。`byKind` 是无原型的 map，快照/恢复后仍是。
+
+`at` 取自事件的 `event.timestamp`，没有时取当前时间。会话回放会把存储的 `ui_telemetry` 事件重新传给 `addEvent`，所以恢复的会话会从历史记录重建时间线。`generation_ms` 字段出现之前记录的事件仍然没有计时数据，与之前一样。和 `generation` 一样，这两个字段都不加到 `models` 上，因为 `models` 也会写入键集合固定的 managed 用量记录。
+
+### D4 — stats 路由字段（第二步）
+
+`GET /session/:id/stats` 把 `timingSamples`（非空时）和 `failures` 复制到 `models[name]`。`ServeSessionStatsModelMetrics` 和 `DaemonSessionStatsModelMetrics` 把这两个字段声明为可选。旧版 daemon 不返回它们，面板就不显示时间线和分布条。每 2 秒一次的全量轮询中，每个模型最多带 200 条计时样本和 50 条失败记录。
+
+### D5 — 速度时间线（第二步）
+
+只要有任一模型有样本或失败记录，就在概览和「按模型」之间显示一张「速度趋势」卡片：
+
+- 横轴是实际时间。每次请求是一个点，颜色与所属模型一致；一条线连接相邻 5 次的中位数，反映趋势而不随每个离群点波动。
+- 切换按钮在输出速度（tok/s）和首 token 延迟（秒）之间切换纵轴，图表任何时候只有一个纵轴。生成窗口不足 100 ms 的响应只出现在首 token 视图中。
+- 失败的请求在图表下方的一条带上用红色 × 标出，两个视图都显示。
+- 鼠标悬停或触摸时，提示框显示最近的那次请求，同时显示十字线和高亮：模型、时间、子 agent、速度、首 token、输出 token 和生成耗时；如果是失败的请求，则显示失败类型。
+- 有两个及以上模型时，图例同时是显示/隐藏开关。隐藏最后一个可见的模型时，所有模型重新显示。
+- SVG 的无障碍名称概括当前指标和每个可见模型的中位数。
+
+### D6 — 卡片上的分布条和失败类型（第二步）
+
+至少有两个可计算速率样本的模型卡片会显示一条分布条：每个样本的输出速度是一个点，并标出 p10–p90 区间和 p50 刻度，所有卡片使用同一刻度；后面跟着 `p50 · p10–p90 tok/s`。计时网格中原有的平均输出速度保留不变。有失败记录的模型按类型列出失败次数，例如 `失败：429 ×2 · timeout ×1`，次数多的在前。
+
+## 兼容性
+
+- 所有新字段都是可选、增量的。旧版 daemon 下的显示与第二步之前相同。
+- 时间线只保留每个模型最近 200 次计时响应，更早的响应仍计入所有汇总值。
+- 通过 `restoreSessionModelMetrics` 恢复的 managed 会话不会恢复样本，和按模型的计时数据一样。
+
+## 不在范围内
+
+- 区分重试和最终失败，以及从成功率中排除内部请求。
+- 样本的增量（`since`）轮询。
+- CLI `/stats` 中的时间线。
+
+## 验证
+
+- **core：** 样本记录事件时间、子 agent 来源，并遵守 200 条上限；跳过没有计时数据的事件、内部请求和没有会话 ID 的事件；失败依次按状态码、错误类型、`unknown` 分类（包括 `__proto__`），`recent` 保持 50 条上限而计数继续增长；`byKind` 在快照/恢复后仍是无原型的。
+- **CLI：** stats 扩展方法返回 `timingSamples` 和 `failures`，为空时省略。
+- **Web Shell 单测：** 两个视图中每个模型的点数、50 ms 窗口不计入速度、失败标记、无障碍摘要、图例切换、最近点和失败的提示框、卡片分布条的分位数、中文失败类型，以及没有样本时不显示时间线。
+- **Web Shell E2E（Chromium）：** 1200px/390px、中英文、浅色/深色。时间线按模型颜色渲染，悬停和点击时提示框打开，× 标记的数量与失败数一致。
+
+## 未决问题
+
+无。

+# Channel Request Owner Approval Implementation Plan
+
+**Goal:** Allow an admitted request owner to approve once or deny in direct and
+group shared sessions while retaining operator-only management and delegation.
+
+**Architecture:** Keep shared-session routing and operator predicates unchanged.
+Record each permission's active run and filter non-operator lookup results by
+that run's attended owner before exposing any request details.
+
+**Tech stack:** TypeScript, existing ChannelBase relay, Vitest.
+
+**Spec:** [Request owner approval](../design/channel-request-owner-approval.md).
+
+## Constraints and Review Focus
+
+- No new public configuration, dependency, route, or automatic migration.
+- Explicit operators, including `[]`, still control shared-session management.
+- Cross-sender, cross-chat, cross-thread, unattended and stale-run IDs must not
+  become owner approvals or leak request titles through ambiguity reporting.
+- `/approve-always` does not gain the shared-session owner exception.
+- Preserve named selection, operator delegation and native-card settlement.
+
+## Task: Request-Scoped Owner Authority
+
+Files: `packages/channels/base/src/ChannelBase.ts`, its collocated tests,
+channel overview and synchronized English/Chinese design documents.
+
+- [x] Add regressions exercising attended owners and denied delegation; run
+      `cd packages/channels/base && npx vitest run src/ChannelBase.test.ts -t 'request owner approval'`
+      and observe owner approvals fail against the existing operator-only gate.
+- [x] Add the private run snapshot and owner filtering; keep all other shared
+      commands on the existing operator predicate.
+- [x] Run the regression subset, then the complete ChannelBase test file.
+- [x] Update the channel overview's request-vs-session permission contract.
+- [x] Run changed-file formatting and lint checks, package compilation, and
+      independent compiled-code reproduction verification.
+- [x] Complete whole-repository build, typecheck, and bundle after synchronizing
+      the installed dependencies and sibling build outputs with this checkout.
+- [x] Read the full diff in two clean self-audit passes, then obtain a fresh
+      code review and fix correctness findings before reporting completion.
+
+The user subsequently requested full verification, an issue following the
+community template, and a linked PR before finishing the full checks. Track the
+reported failure in [#16086](https://github.com/QwenLM/qwen-code/issues/16086).
+Submission does not authorize a release, merge, or deployment.
+
+## Verification Evidence
+
+- The first 28 owner regressions failed against the original operator gate,
+  then passed after the fix. The complete updated file passed 783 tests.
+- `npm run build` from `packages/channels/base` passed; changed-file ESLint,
+  Prettier and whitespace checks passed.
+- Independent compiled ChannelBase inbound/event verification passed 33
+  scenarios, including a real isolated PairingStore. This is not live IM E2E.
+- After refreshing pinned dependencies and synchronizing main, root
+  `npm run build`, `npm run bundle`, and
+  `NODE_OPTIONS=--max-old-space-size=6144 npm run typecheck` passed. The refreshed
+  ChannelBase test file passed all 783 tests again.
+- Independent concurrent-session verification passed 13 scenarios, including
+  ordinary-member isolation and the existing operator delegation behavior.
+- A fresh bundled CLI, isolated extension transport, real ACP child, local
+  OpenAI-compatible fixture, and real edit tool passed five end-to-end cases:
+  direct approval, group approval after another member's rejection, group
+  denial, persistent/management rejection followed by one-time approval, and
+  privately paired approval. Approved edits changed files; denial preserved
+  the file and completed the attended lifecycle without a second request.
+- CI static checks, TUI snapshots, and no-AK integration passed on the tested
+  production head. Full Linux unit and Web Shell smoke jobs were still running
+  when this evidence was recorded. No live IM or all-platform acceptance is
+  claimed.
+- Independent review found no actionable correctness or security defects. Its
+  suggested original-owner-versus-current-sender regression was added and
+  included in the final 783-test run. An active unattended loop/webhook case
+  remains outside the independent integration coverage; the owner filter and
+  existing automation authorization were inspected without broadening them.

 | `security.allowedInsecureVoiceBaseUrls` | array of strings | Complete voice provider base URLs that may use HTTP or resolve to private-network addresses. Each entry must include an explicit `http://` or `https://` scheme and the full path (for example, `/v1`); only URL serialization and trailing slashes are normalized. Wildcards are not supported; metadata, link-local, local-use NAT64, 6to4, and Teredo addresses remain blocked even when listed, as do hostnames that resolve to loopback; IPv4-mapped, IPv4-compatible, and well-known NAT64 (`64:ff9b::/96`) literals are classified by their embedded IPv4 address. Only User, System, and SystemDefaults scopes are honored. Use only for trusted endpoints in managed private networks. Cleartext HTTP also exposes the provider API key transmitted in the Authorization header. An allowlisted hostname is only as trustworthy as its DNS; prefer IP-literal entries when the gateway address is stable. The exact match covers the batch request URL; streaming transports connect to a WebSocket URL derived from it (same scheme, host, and port, `/api-ws/v1/...` path), not to the allowlisted path itself. | `[]`        |

+## Submitted prompts
+
+In headless runs, `prompt.submit` fires for each prompt a person submits, before
+UserPromptSubmit hooks and before `@` references are read. A hook can rewrite the
+prompt, attach context the model reads beside it, or drop it:
+
+```javascript
+export function register(on) {
+  on('prompt.submit', ($, e, next) => {
+    if (/AKIA[0-9A-Z]{16}/.test(e.text))
+      return { drop: 'the prompt holds an AWS access key' };

+      context: [...(e.context ?? []), 'Answer in British English.'],
+    });
+  });
+}
+```
+
+The hook receives:
+
+| Field     | Value                                                                                 |

+`origin`, `wait` and `turnId` are pinned. The prompt that enters is the one that
+arrives beneath the hooks: `next(e)` resolves to `{text, context?, origin}`, and
+what a hook answers after its `next` resolved changes nothing. The rewritten text
+is what the model reads, what `turn.start` hears and what the transcript keeps.
+In a stream-json message with blocks other than text, the rewrite replaces its
+text blocks and the other blocks follow it.
+The context goes to the model after the prompt, in the block that holds
+UserPromptSubmit's context, ahead of it, and is never shown as part of the
+prompt.
+
+`{drop: reason}` stops the prompt before UserPromptSubmit and before any model
+request. The run ends with the error result `Prompt dropped by a hook: <reason>`
+and exit code 1; a stream-json session goes on to its next message. The reason
+is one line, kept to its first 4,096 characters. A hook that answers without
+calling `next` and without a drop also stops the prompt, with the result
+`Prompt not submitted: a hook answered without passing the prompt on`. A hook
+that calls `next` and then answers a drop fails, and its `next` stands.
+
+A hook that fails or times out is skipped, so a broken guard never blocks a
+prompt. Give a guard a `.catch` that drops instead:
+
+```javascript
+on('prompt.submit', guard).catch(($, e, next) =>
+  next.called ? next(e) : { drop: 'the guard failed' },
+);
+```
+
+A prompt longer than 128 KiB as JSON reaches no hook, and the line

+where transcript logs do.
+
+These differ from Claude Code:
+
+- `prompt.submit` runs only in headless runs; the Ink and OpenTUI terminals skip

+- Slash commands, background notifications and the continuation of an

+- `attachments` never appears, and `$.prompt.media` does not exist.
+- A UserPromptSubmit hook that blocks the prompt beneath does not turn `next(e)`

Other members' messages queue instead of steering. Sessions that are not shared belong to their own sender, who may always use them.
+
+An admitted sender may use `/approve` (allow once) or `/deny` for their own pending tool request in their current attended turn, in direct messages and groups. This request-specific authority does not depend on `operators`, even when the list is empty. Another ordinary member cannot answer it, and an attempt from another chat or thread is rejected. Operators may still answer another sender's text permission request in the same chat and thread; native interactive cards retain their existing owner checks.
 
 Set `operators` to the user IDs allowed to manage shared sessions. Omitted or empty `operators` grants nobody this role. Private allowlists, user pairing, group pairing, and group member lists never imply operator permissions. Operators must still pass normal conversation admission.

 Two things to know. With only the built-in target default, a continuation keeps the interrupted run's recorded **effort**. An explicit `--effort`, a project-remembered level, the operator `review.effort` setting, or an effective `--comment` supplies a required level; if it differs from the interrupted run, resume is refused and a fresh run starts at that level, because different effort is different work. And if the PR head moved while the review was down, the resume refuses (`head-moved`) and the fresh run reviews the new commits — which is what you want, and it counts as this review's one restart.
 
+`--resume` is **not** the flag for a re-review after the PR gained commits: just run `/review 123` again. At high effort a plain re-review reads the previous round's anchor and scopes itself to the new commits (plus the files that import them); lower efforts review the full diff. At high and medium effort it also rules on every finding the previous round posted; a `low` pass reads no ledger, so it neither re-rules nor carries those findings. After a completed round there is nothing to resume — cleanup removes the run's state, so `--resume` refuses as `no-report` and costs nothing. `worktree-gone` is a different shape: the attempt's report survived but its worktree vanished — nothing to continue, and no restart charged either. The `head-moved` refusal (and its one-restart cost) applies only when an interrupted attempt's state survived.

 ## Findings as Data
 
 Confirmed findings are canonicalized into `.qwen/tmp/qwen-review-<target>-findings.json` before anything else consumes them — the terminal report, the saved Markdown report, and the PR review JSON all read that one artifact instead of re-typing the list. Each finding carries a unique `id` (what outcomes and resolved anchors join on), `severity`, `confidence`, `source`, `summary`, a `shortSummary` capped at 60 characters for list rendering, `failureScenario`, and one or more `locations` — a pattern-aggregated finding keeps **one location per occurrence**, so each still gets its own inline comment.

It is also not the flag for a re-review after the PR gained commits — see **Resuming an interrupted review** above for what a plain re-review does at each effort and which refusal each surviving state produces.
 
 A time-budgeted run can also export a **soft** deadline so the review stops its open-ended reverse-audit loop while there is still time to verify, compose and post: `QWEN_REVIEW_DEADLINE_EPOCH` is the Unix-seconds moment the run will be killed, and `QWEN_REVIEW_DEADLINE_RESERVE_SECONDS` (default 4800; `0` keeps only the round estimate) is the tail that must remain for the last round's verification, `compose-review` and submission. When the remaining budget no longer fits another round plus that tail, the round builder refuses to build it, and the composed verdict discloses the truncated audit (an otherwise-Approve verdict is capped at Comment). Without that variable the review uses the wall its plan recorded at capture: `--deadline <minutes>` on `qwen review fetch-pr` / `capture-local` / `plan-diff`, or by default **8 hours** on a small (Step 3A) diff, **12** on a large (3B) one and **16** on a huge one — sized by the diff's own lines, so a critical-posture fix-audit round keeps the wall its delta's size earns even though it fans out per territory and takes the chunked round cap. That default is a liveness bound — sized above what a healthy run at the round cap spends — so it ends a loop that has stopped converging and leaves a run that keeps working untouched; it is charged in elapsed time, idle included, so a session left overnight spends it, and because the next round is priced from the previous round's admission, a multi-hour pause between rounds can stop a run with time still on the wall (a `--resume` from a new session restarts both the wall and the pricing; **Review Deadline** below gives the ceilings). It stops the loop at the next round admission or verify build; it does not interrupt a build already running. A plan-recorded wall keeps a third of itself (capped at 4800 seconds, floored at the compose floor) as the tail reserve unless the reserve variable is set; a `--deadline` that cannot hold a convergence (two rounds plus that reserve — at or under ninety minutes, or more when the shell's reserve or compose-floor overrides raise the bar; that second leg is skipped while the environment exports a well-formed epoch, since the flag is inert then, and the wall it records is priced again in whatever shell a later env-less `--resume` runs in) is refused up front, and a wall just above it can still stop before round 1 once the fan-out and verification have spent it. When the wall can no longer admit a rebuild the coverage check would otherwise prescribe (a reverse-audit round, or a verifier shard under the compose floor), `compose-review` withholds that `FIX:` line and prints a `NOTE:` line saying so, with the gate's arithmetic; the gap is still disclosed in the posted body. The plan wall bounds the round builder and the verifier; two readers stay on the environment alone — the generated review workflow's launch allowance, and `qwen review run`'s own `--timeout-minutes` kill, which is not exported as a deadline. The plan stores the wall as a duration from the attempt's start, so a `--resume` from a new session renews it (a same-session resume continues the attempt and its wall; the flag itself is ignored on a resumed run — only its grammar and the default rule are checked — and the run says what wall the plan holds and how much of it is left, or that it has run out, and which builds the gates will now refuse; a wall can only run out on a same-session resume, or when the ledger failed to record the attempt, so the cheapest way past it is to resume from a new session, which renews the wall and keeps the worktree; a fresh review without `--resume` records a new wall too, and `--deadline none` on that fresh capture records none). `--deadline none` records no wall and leaves the loop bounded by the round cap alone — unless the environment exports an epoch, which clocks the run regardless. The `/review` slash command does not take the flag: it warns and drops it together with a value that could be one (whole minutes, or `none` — so a PR number typed right after it is dropped too), while any other value after it is disposed of like an invalid `--effort` value (a PR URL becomes the target; a typo is reported, and survives only as a sole file-shaped token), and a skill-driven run always uses the default. The huge tier's round reduction (3 rounds instead of 5) keys on an explicit deadline only — the environment's or the flag's — never on the default. A malformed environment deadline falls through to the plan's wall; a malformed plan field leaves the review ungated — the outer timeout still bounds the run.

 ### Maintenance commands
 
-`bin/qwen-managed-agent-admin <command> [arguments]` runs the offline maintenance entry points, such as `storage-registration`, `workspace-migration` and the CSI commands, from the server jar through Spring Boot's `PropertiesLauncher`. Run it without arguments to list the commands, and run a command without arguments for its usage. Like the server launcher, it uses `config/application.yml` when that file exists and `SPRING_CONFIG_ADDITIONAL_LOCATION` is not set. Most commands that open the database take their own credentials rather than `server.env`'s `SPRING_DATASOURCE_*`: the Workspace commands read `W1_JDBC_URL`, `W1_JDBC_USER` and `W1_JDBC_PASSWORD`, and the CSI commands read `K2_JDBC_URL`, `K2_JDBC_USER` and `K2_JDBC_PASSWORD`. Two are exceptions: `operator-recovery` and `resident-retirement` start the server's Spring configuration and use its datasource, so they read `SPRING_DATASOURCE_URL`, `SPRING_DATASOURCE_USERNAME` and `SPRING_DATASOURCE_PASSWORD`, together with the other control-plane settings, from the environment and `config/application.yml`; run them with `server.env` loaded. `csi-protection` opens no database, and neither does `resolved-configuration`, which prints the Runtime state directory, auth mode and trusted actor header that the server's configuration resolves to in the environment it runs in; the upgrade command runs it the same way to find the Runtime state. Each command is an offline procedure with its own preconditions, documented with it; meet them before running it. `bin/qwen-managed-agent-operator-recovery` remains the entry for the Hosted Shell recovery procedure, and `bin/qwen-managed-agent-admin operator-recovery` runs the same command.

 ### Upgrade

   - `check` and `backup` take the Runtime state directory from the server's own configuration. They run the new release's server jar as the control-plane unit runs the server: with its account, working directory and environment, and the launcher's default `config/application.yml` when `SPRING_CONFIG_ADDITIONAL_LOCATION` is unset or empty. The jar prepares Spring's environment the way the server does, so every configuration file, import and profile counts, as do `SPRING_APPLICATION_JSON`, system properties from `JAVA_TOOL_OPTIONS` and relaxed names, and a relative directory is resolved in the unit's working directory. It starts nothing and opens no connection. When it cannot resolve the configuration, or the unit passes the launcher arguments, which `systemctl` does not print exactly, `backup` refuses until `--runtime-state <directory>` names the directory the server uses, or `--runtime-state none` says it keeps none. Without a configured directory, as on a deployment without the tool path, `backup` archives no Runtime state and says so.
 - `install --backup <directory>` refuses a backup of another release, a backup file that changed, a backup the control plane has started since, and a backup of another database than the unit's `SPRING_DATASOURCE_URL` names. It copies the release to `<distribution>-releases/<version>`, such as `/opt/qwen-managed-agent-releases/<version>` (`--releases` names another directory; pass the same one to every phase), copies operator files from the installed `config/` with their owner and mode, and points the distribution path at the new release with one rename. The copy's own files, those `SHA256SUMS` lists, are made readable by every account, so the service account can run a release extracted with a restrictive umask. The first run moves the installed directory to `<releases>/<old version>` and puts a link in its place, so the units keep their paths. The previous release stays where it is. An existing `<releases>/<version>`, such as the archive extracted there, is used only when its `SHA256SUMS` is the new distribution's and its files match it, and its listed files are made readable the same way; a copy that fails is removed. A crash between the first run's two renames leaves `<distribution>.upgrade-<suffix>` beside the missing distribution path; every phase then names the `mv -T` that finishes the install. An install killed at another step can leave a partial copy `.<version>.partial-<suffix>` in the releases directory, an `<distribution>.upgrade-<suffix>` link beside the distribution path, or an operator file's `.tmp-<suffix>` copy in the new release's `config/`; the `layout` row lists them, and the next `install` removes them. The suffix is the eight hexadecimal digits `install` generates, so an operator's own `<distribution>.upgrade-backup` is left alone. Run again once the release is installed, as after an interrupted session, `install` says so and points at `start`.
 - `start` refuses before `install`, and while the Harness Broker settings still need step 5 below. It starts the Harness, or restarts one that an earlier `start` left running so that it reads what was fixed since, runs `bin/qwen-managed-agent-server --check` as the service account with the unit's environment, starts the control plane only when that passes, and waits for a healthy actuator (`--timeout`, 300 seconds by default; one probe waits at most 5 seconds). Flyway migrates the schema during this start. A control plane that exits before it is healthy is stopped and reported, even one that systemd's `Restart=on-failure` would bring up when it runs it again: an exit during the start that migrates the schema is worth reading in the journal before `start` runs again. One that is still not healthy at the timeout keeps running; read its journal, then run `verify`, or `stop` and `start` again.
+  - `start` and `verify` find the Harness, the control plane and its health endpoint the same way, so a port or address set where `server.env` does not show it counts: in a configuration file, on the command line or in `SPRING_APPLICATION_JSON`. The Harness is where `qwen.managed-agent.harness.base-url` says. The control plane is where `server.port`, `server.address` and `server.ssl` bind it, with a wildcard address reached on the loopback interface, and the health endpoint follows Spring Boot's management settings: a `management.server.port` of its own moves it to that port, on `management.server.address` and under `management.server.base-path`. `--server-url <url>` names the control plane instead, for example behind a proxy, and the health endpoint is then `<url>/actuator/health`. A port of 0 or below gives no URL to wait on, so both phases refuse until `--server-url` names one; they also refuse a listener no URL can name, such as a link-local IPv6 address with its zone. When the configuration does not resolve, or the unit passes the launcher arguments, they use the URLs `server.env` names and print a line that says so.
 - `verify` runs `--check --online` the same way and reads the actuator, waiting up to `--timeout` (300 seconds by default) for its answer. With `--tenant <id>`, it reads the tenant's most recent Session and its Items, before `--turn` creates one; `--turn` creates a Session and waits for one Turn, which calls the model, polling past a `5xx` answer or a dropped connection; when the Session read is skipped, the `turn` row says so. No request outlasts `--timeout`. A request without an actor lists only Sessions outside Workspaces; `--actor <id>` sends one through the header `QWEN_MANAGED_AGENT_TRUSTED_ACTOR_HEADER` names. `verify` reads the auth mode the way `backup` reads the Runtime state directory, and signed authentication skips both reads; read a Session through the ingress instead.
 
 The command starts and stops units only. It never stops ingress, installs Qwen Code, edits environment or unit files, or deletes a release. When `check` warns that a unit template changed, carry the change over to the installed unit and run `systemctl daemon-reload` before `start`.

 - `install --backup <目录>` 拒绝其他版本的备份、内容有变化的备份文件、控制面在备份之后又启动过的备份，以及所导出的数据库与 unit 的 `SPRING_DATASOURCE_URL` 不同的备份。它把新版本复制到 `<分发路径>-releases/<version>`，例如 `/opt/qwen-managed-agent-releases/<version>`（用 `--releases` 指定其他目录，并在每个阶段都传同一个），把已安装版本 `config/` 中的运维文件连同属主和权限复制过去，再用一次 rename 把分发路径指向新版本。副本中属于版本自身的文件（即 `SHA256SUMS` 列出的文件）会设为所有账号可读，所以即使解压时用了严格的 umask，服务账号也能运行该版本。第一次运行会把已安装的目录移到 `<releases>/<旧版本>`，并在原位置放一个链接，因此 unit 中的路径不变。旧版本保留在原处。已存在的 `<releases>/<version>`（例如直接解压到那里的发行包）只有在其 `SHA256SUMS` 与新分发产物相同、且文件与之相符时才会被使用，其中列出的文件同样会设为所有账号可读；复制失败时会删除复制出的内容。如果第一次运行在两次 rename 之间崩溃，分发路径会缺失，旁边留下 `<分发路径>.upgrade-<后缀>`；此后每个阶段都会给出完成安装所需的 `mv -T` 命令。在其他步骤被杀掉的 install，可能在版本目录里留下部分副本 `.<version>.partial-<后缀>`，在分发路径旁留下 `<分发路径>.upgrade-<后缀>` 链接，或在新版本的 `config/` 里留下运维文件的 `.tmp-<后缀>` 副本；`layout` 行会列出它们，下一次 `install` 会删除它们。后缀是 `install` 生成的 8 位十六进制数，因此运维自己的 `<分发路径>.upgrade-backup` 之类不会被删除。版本安装完成后再次运行（例如会话中断后），`install` 会说明已经安装并提示运行 `start`。
 - `install` 之前，以及 Harness 的 Broker 配置仍需按下文第 5 步修改时，`start` 会拒绝执行。它先启动 Harness（如果之前某次 `start` 留下了正在运行的 Harness，则重启它，以读入此后修改过的内容），再以服务账号、按 unit 的环境运行 `bin/qwen-managed-agent-server --check`，通过后才启动控制面，并等待 actuator 报告健康（`--timeout`，默认 300 秒；单次探测最多等待 5 秒）。Flyway 在这次启动中迁移 schema。控制面在健康之前退出时会被停止并报告，即使 systemd 的 `Restart=on-failure` 再次运行它就能起来也是如此：迁移 schema 的这次启动中出现了退出，应先查看日志，再重新运行 `start`；超时仍未健康时控制面保持运行，请查看其日志，然后运行 `verify`，或先 `stop` 再重新 `start`。
+  - `start` 和 `verify` 以同样的方式确定 Harness、控制面及其健康端点的位置，因此在 `server.env` 看不到的地方设置的端口或地址也会生效：配置文件、命令行或 `SPRING_APPLICATION_JSON`。Harness 的位置由 `qwen.managed-agent.harness.base-url` 决定。控制面的位置由 `server.port`、`server.address` 和 `server.ssl` 决定，通配地址经回环接口访问；健康端点遵循 Spring Boot 的 management 设置：单独设置的 `management.server.port` 会把它移到该端口，绑定 `management.server.address`，并位于 `management.server.base-path` 之下。`--server-url <url>` 可改为指定控制面的地址，例如位于代理之后，此时健康端点为 `<url>/actuator/health`。端口为 0 或负数时没有可等待的 URL，因此两个阶段都会拒绝执行，直到用 `--server-url` 指定一个；URL 无法表示的监听（例如带 zone 的 IPv6 链路本地地址）同样会被拒绝。无法解析配置，或者 unit 给 launcher 传了参数时，它们使用 `server.env` 中给出的 URL，并打印一行说明。
 - `verify` 以同样方式运行 `--check --online` 并读取 actuator，最多等待 `--timeout`（默认 300 秒）让它应答。指定 `--tenant <id>` 时，它在 `--turn` 创建 Session 之前读取该租户最近的 Session 及其 Item；`--turn` 会创建一个 Session 并等待一个 Turn 完成，这会调用模型，轮询遇到 `5xx` 应答或连接中断时会继续；跳过 Session 读取时，`turn` 行会说明这一点。任何请求都不会超过 `--timeout`。不带 actor 的请求只能列出 Workspace 之外的 Session；`--actor <id>` 通过 `QWEN_MANAGED_AGENT_TRUSTED_ACTOR_HEADER` 指定的请求头带上一个 actor。`verify` 按 `backup` 读取 Runtime 状态目录的方式读取认证模式；使用签名认证时两项读取都跳过，请通过入口读取 Session。
 
 该命令只启动和停止 unit，不会停止入口流量、安装 Qwen Code、修改环境文件或 unit 文件，也不会删除任何版本。`check` 提示 unit 模板有变化时，请在 `start` 之前把变化同步到已安装的 unit，并执行 `systemctl daemon-reload`。

+The path and filename above are examples for these service-manager templates, not a built-in location that Qwen Code discovers automatically. Daemons started through `qwen daemon start` can instead opt into the built-in `--save-token` sidecar and `qwen daemon token` command; see [Inspect and control a local daemon](./qwen-serve.md#inspect-and-control-a-local-daemon). The systemd and launchd templates below still pass the token explicitly because they invoke `qwen serve` directly. See [Authentication](./qwen-serve.md#authentication) for the token-selection rules.
 
 > **Scope this `export` to the current shell session only.** Don't add it to `~/.bashrc` / `~/.zshrc` — a profile-level export exposes the bearer token to every process spawned from that shell (IDE subprocesses, browser debuggers, `npm` scripts from unrelated projects). For long-running setups, use the systemd `EnvironmentFile=` / launchd `EnvironmentVariables` mechanisms below — both scope the token to just the daemon process.

-> **🚧 v0.16-alpha**: `qwen serve` first ships to npm in v0.16-alpha as **text-only chat / coding** with **local-only deployment**. Image / file attachments on the prompt path, containerized deployment (Docker / k8s / nginx reverse-proxy), and remote / multi-daemon hardening land in a follow-up patch when an enterprise pilot is committed. See [v0.16-alpha known limits](#v016-alpha-known-limits) for the full deferred list.

-> **Status:** Stage 1 (experimental). The protocol surface is locked at the §04 routes table from issue [#3803](https://github.com/QwenLM/qwen-code/issues/3803). Stage 1.5 (`qwen --serve` flag — TUI co-hosts the same HTTP server) and Stage 2 (in-process refactor + `mDNS`/OpenAPI/WebSocket/Prometheus polish) are immediately downstream.
->
-> **Scope honesty:** Stage 1 is sized for **developers prototyping clients against the protocol surface** and for **local single-user / small-team collaboration**. Production-grade multi-client / long-running / network-flaky workloads (mobile companions, IM bots reaching 1000+ chats) need Stage 1.5+ guarantees that aren't in this release. See [Stage 1.5+ runtime guarantees](#stage-15-runtime-guarantees) for the full gap list and #3803 for the convergence roadmap.

   - **Known limit — token-cost amplification:** the route is a pure-cost endpoint (each call is an LLM side-query, no state benefit) and the daemon has no per-route rate limit in v1. On a no-token loopback default a buggy or malicious local client can spam it to burn tokens. Configure `--token` (and optionally `--require-auth`) on shared dev hosts before exposing the daemon.
   - **Concurrent recap safety:** two simultaneous `/recap` calls on the same session run two independent side-queries. `generateSessionRecap` reads a snapshot of the chat history via `GeminiClient.getChat().getHistory()` and feeds it to a separate `BaseLlmClient.generateText` call (via `runSideQuery`); it never appends to or mutates the session's `GeminiChat`. Safe to call from multiple clients without coordination.
 
-## v0.16-alpha known limits
+## Deployment and security notes
 
-The first npm release of `qwen serve` (v0.16-alpha) is intentionally narrow — text-only chat / coding for developers running the daemon on their own machine. The list below makes the deferred surface explicit so adopters can plan around it; everything here is on the v0.16.x patch roadmap or a near-term follow-up release.
-
-**Product surface — text-only:**
-
-- ✅ Text prompts and text responses (chat, coding, tool calls, MCP integration)
-- ❌ **Image / file attachments on the prompt path** — `MessageEmitter` currently only renders text; multimodal echo lands when an alpha target with image needs is committed (#4175 chiga0 #27 P0 item)
-- ❌ **Streaming uploads** — same gating as multimodal
-
-**Deployment surface — local-only:**
-
-- ✅ Loopback (`127.0.0.1`, default) — no auth required, suitable for dev workstations
-- ✅ Local launch via `systemd` / `launchd` / `nohup &` / `tmux` — see [Local launch templates](./qwen-serve-deploy-local.md)
-- ✅ Bring-your-own bearer token via `QWEN_SERVER_TOKEN` env var ([Authentication](#authentication) for setup)
-- ❌ **Containerized deployment** — Docker / Compose / Kubernetes / nginx reverse-proxy with TLS termination NOT in v0.16-alpha. Defers to v0.16.x once an enterprise pilot is committed (would otherwise rot from no-one-validating).
-- ❌ **Multi-daemon coordination on one host** — one daemon can host several explicitly registered workspaces, but daemons do not coordinate with each other. Cross-host federation, instance-path token keying, and stale-token cleanup defer to v0.16.x.
-- ✅ **Revocable Local Control pairing tokens** — `--local-control` mints a separate LAN pairing token owned by the daemon. General daemon token storage remains BYO-token.
-
-**Hardening — minimum viable for local single-user:**
-
-- ✅ Boot-time security gate (non-loopback binds always carry a bearer token — operator-supplied or generated at startup; explicitly empty sources still refuse to boot, [PR 15 / #4236](https://github.com/QwenLM/qwen-code/pull/4236))
-- ✅ Mutation-route auth gate, session-scoped permission routing (Wave 4 PRs)
-- ✅ MCP guardrails + multi-client permission coordination (F2 / F3)
-- ✅ **Prompt absolute deadline + SSE writer idle timeout** — opt-in via `--prompt-deadline-ms` and `--writer-idle-timeout-ms`; advertised through `prompt_absolute_deadline` and `writer_idle_timeout` when enabled.
-- ✅ **HTTP rate limiting** — opt-in via `--rate-limit` and per-tier thresholds; advertised through `rate_limit` when enabled.
-- ⏸️ **Prometheus metrics + load test harness** — defers to v0.17 F4 Phase-1 scale instrumentation when 30-50 active sessions becomes a real target.
-- ⏸️ **`--max-body-size` CLI flag** — daemon enforces `express.json({ limit: '10mb' })` by default which comfortably covers text-only prompts (model context windows are well under 10 MiB of chars). Tunable via flag in v0.16.x.
+- **Loopback is trusted by default** — `127.0.0.1:4170` starts without bearer authentication, and every local process that can reach it receives full API authority, including code execution as the daemon user. Use a stable `QWEN_SERVER_TOKEN` with `--require-auth` on shared or untrusted hosts.
+- **Non-loopback listeners always carry a bearer token** — supply your own token or use the ephemeral token printed at startup. Generated tokens rotate on restart, so reusable clients need a stable token. HTTP is unencrypted; configure TLS before crossing untrusted networks.
+- **Background launch has two paths** — use `qwen daemon start` for built-in local lifecycle management, or the [systemd / launchd / tmux / nohup templates](./qwen-serve-deploy-local.md) when you need service-manager supervision or startup after reboot.
+- **Token persistence is opt-in** — `qwen daemon start --save-token` stores an explicitly supplied bearer in an owner-only sidecar for `qwen daemon token`; ordinary `qwen serve` and generated tokens do not use that sidecar. See [Inspect and control a local daemon](#inspect-and-control-a-local-daemon).
+- **Multi-workspace is single-operator** — registered workspaces share the daemon's bearer token, listener, quotas, and process fault boundary. Use separate daemons and an external orchestrator for independent users or security principals; see [Multi-session & multi-workspace deployment](#multi-session--multi-workspace-deployment).
 
 For the deeper "what we won't fix in Stage 1" enumeration (single-host session-state mutation model + N parallel sessions sharing one ACP child inside each workspace runtime), see [Stage 1 scope boundaries](#stage-1-scope-boundaries--what-we-wont-fix-in-stage-15) below.

 `qwen daemon start` spawns `qwen serve` detached, waits for its discovery record, and prints the bound URL, PID, log path, and stop command. It drops the launching session's identifiers and private capability bindings so the child is a fresh daemon, keeps the operator's model/auth environment, and passes `--no-token-qr` so the startup log cannot contain a token. Workspaces are canonicalized, relative runtime directories are pinned to the launching directory before spawn, and Windows drive-relative roots are resolved against the launching drive. A non-loopback bind requires `QWEN_SERVER_TOKEN`; use `qwen serve` directly if you want an ephemeral token. The startup log is `0600` and is removed after a successful start. `--wait` waits until the runtime is serving (no `daemon_runtime_starting` issue and not `error`); a timeout keeps the startup log and exits non-zero.
 
+For an authenticated background daemon with a reusable local credential, supply a stable token through the environment and opt in to the token sidecar:
+
+```bash
+export QWEN_SERVER_TOKEN="$(openssl rand -hex 32)"
+qwen daemon start --require-auth --save-token --wait
+qwen daemon token --port 4170          # print the saved bearer; treat the output as a secret
+qwen daemon token --port 4170 --remove # delete only the local sidecar
+```
+
+Prefer `QWEN_SERVER_TOKEN` over `--token`, which is visible in the shell process list. `--save-token` requires an explicitly supplied token and refuses to spawn without one. The sidecar is `daemon/daemon-<port>-<pid>.token` under the same runtime directory as the discovery record; it is `0600` on POSIX and is never included in the discovery record or daemon log. `qwen daemon stop` removes it, while `qwen daemon restart` carries it to the replacement instance. `qwen daemon token --remove` deletes the local copy but does not change or revoke the running daemon's credential; stop and start the daemon with a new token to rotate it. Ordinary `qwen serve`, including `--open-with-auth`, does not write this sidecar.
+
 `qwen daemon restart` stops one registered daemon through `daemon stop` and starts it again through `daemon start --wait` on its recorded port and hostname, with its recorded startup workspaces, Web Shell mode, and `--require-auth` setting; `--web`/`--no-web` and `--require-auth`/`--no-require-auth` override the record. Persisted workspace registrations are restored by the new daemon itself, not replayed as `--workspace`. Every other `qwen serve` option (for example `--profile`, `--channel`, `--allow-origin`, or rate limits) resets to its default, so relaunch a daemon configured with those through `qwen serve`. Before stopping anything, restart refuses an HTTPS daemon, a startup workspace that no longer exists, a run from inside a shell the daemon hosts (such as its Web Shell terminal), and a bearer daemon without `--token` or `QWEN_SERVER_TOKEN`; a running bearer daemon must accept the token, so restart never rotates the credential. A token kept only in a workspace `.env` or settings file is not read by `qwen daemon`. `--force` is forwarded to `daemon stop` only when you pass it. If the recorded port is taken, the daemon starts on the next free port and restart exits non-zero.

@@ -1361,3 +1361,19 @@ A scripted deep verification of the round-3 head (50/55 assertions, 17 mutants)
 **The option-injection fence was not observable.** The round-3 injection test asserted only that no config reached the runner — an observable git's own rejection of a malformed option produces identically, so deleting the hex guard survived the mutation run (M15, the only survivor of 17). The fence is now pinned directly with a spawn spy: a non-hex merge base must never spawn git at all, and a hex-shaped nonexistent one must (positive control) — the guard, not git, is the thing under test.
 
 The verification also corrected the record on the bot review's second example: the `$/` prepare-release-runner ignore in the base config is precautionary — no workflow at this head uses the form (the bot's "8 release/build workflows" claim does not hold); the `queue` exception is the one reachable path-scoped case, at line 485 of the workflow named above.
+
+### The prose re-review request
+
+On 2026-10-31 a maintainer asked what happens when, after a completed round, the PR gains commits and the user types "有更新了，重新评审". Reading the entry path surfaced two gaps, neither visible from the pipeline side.
+
+First, the parser does not refuse prose. `classifyToken`'s fallback classifies every non-flag, non-integer, non-URL token as a FILE target, and target selection took the first classifiable token — so the sentence becomes a file path and the round dies capturing it, and, worse, prose typed _beside_ a PR number steals the target while the number is demoted to `extraTokens` with only an "Ignoring extra argument(s)" warning. Reproduced as a red unit test before the fix (`有更新了，重新评审 6711` classified as `file`). The fix is deliberately not a prose heuristic — Unicode paths are legitimate file targets, and guessing which token is a "sentence" is the same guessing the parser exists to eliminate. Instead: PR-shaped tokens now outrank file-shaped ones regardless of arrival order (an explicit `./6711` spelling is not PR-shaped and stays a file target when no PR-shaped token is present; beside one, the PR wins and the path is disclosed), and a Step 1 intent-routing clause handles the no-target case — resolve the PR from the conversation, copy the explicitly named number or URL into a parser input file of the run's own, keep the CLI's args file as the record of what was asked, and ask when no unique PR is recoverable. The clause is the one sanctioned departure from the copy-verbatim rule, scoped to inputs carrying no classifiable target at all, so the transcribed-argument defense above stays intact.
+
+Second, `--resume` read as "re-review". Its description said "continue an interrupted review … instead of starting over" with nothing excluding the updated-PR case, and a resume refused with `head-moved` spends the run's one head-movement restart without a word about either fact. The description and the resume verdict bullet now name the exclusion (a re-review after new commits is a plain run whose delta the incremental check scopes), and the refusal stderr teaches the same at the moment of misuse. The restart-bound semantics are deliberately unchanged: the fresh fall-through run IS the post-head-movement restart, and charging it is the existing design, not a defect this incident established.
+
+The first review round (#15998) then caught two defects in the routing clause itself, both reproduced against the exact commit before fixing. **Option-only hijack:** the clause's condition — non-empty, no classifiable target — literally matches `/review --fix` and `/review --effort low`, supported local invocations; resolving the conversation's last PR into them would retarget a working-tree run and disarm `--fix` (effective only on local/file targets). The clause now names both non-intent shapes explicitly — bare and option-only — and leaves them to the parser verbatim. **Authorization break:** the clause promised that a `--comment` carried through the resolution "keeps its posting authority", but the write gate re-parses the CLI's verbatim record on purpose — a model-written resolution is exactly the untrusted source that design refuses — so a prose record ends the run at `submit` with `unbound` after the whole review ran. The promise was false and is gone: posting is now the resolution's hard boundary. When the resolved verdict has `comment.effective` true, the skill presents the resolved invocation and asks the user to re-invoke it explicitly — that invocation's CLI record authorises normally — instead of running a review whose submission is already refused. Making the resolution itself an authorization source would mean trusting a model-written file at the write gate, which is the one thing the gate exists to refuse; the boundary, not a new trust channel, is the fix. Both shapes are pinned: the parser contract for option-only invocations, the gate's `unbound` refusal of a prose record beside the explicit re-invocation's acceptance, and the clause's boundary sentences. The round's non-blocking nit also proved real once pinned as a test: the PR-shape reorder moved a malformed URL behind the assigned target, where it lost its specific "not a PR/CR URL" diagnostic to the generic extra-argument line — a small regression the reorder introduced. The invalid-url refusal is now hoisted ahead of the target-assigned branch, so the diagnostic is position-independent, and a test pins both its presence and the absence of the generic line beside it.
+
+The deep-verification round (head `ef86b03a99`) then measured one more hole in the same class and one overclaim. **F1 — prose local-write hijack:** the option-only exclusion named the flags-alone spelling, but "review my local changes --fix" is prose with no classifiable target, so it still matched the trigger and resolution would disarm `--fix` exactly as before — one prose word past the fixed boundary. The fix is keyed on the parser verdict, not on wording: the clause now parses the verbatim input first and never resolves a PR into a verdict with `fix.effective: true` (a local-write invocation whatever its prose says); prose asking for a LOCAL review is excluded even without `--fix`. The same round's `#15998` cell exposed a copy ambiguity — the hash form is not PR-shaped, and "copy it, do not reconstruct it" left the `#` undecided — so the clause now states that a `#` prefix is reference decoration, not part of the target. **F2 — scoping overclaim:** "a plain re-review scopes the delta" is true only at high effort (the incremental cache is high-only); the docs, the resume bullet, the `--resume` help, and the head-moved stderr now all carry the high-effort qualification. The `./` escape-hatch wording gained the same precision the sibling cells measured: it holds when no PR-shaped token is present, not unconditionally.
+
+The `/review` lane's round on `6a5372d6e4` then filed five suggestions, all verified against the code before fixing. **R1-1:** the routing clause's rationale described the prose-steals-target behavior in the present tense — behavior this same PR's parser preference removes; a prompt read on every run must not re-derive a closed bug, so the sentence now marks that half as pre-fix and keeps the live half (prose alone dies at capture) as the rationale. **R1-2/R1-3:** the head-moved guidance was gated on a refusal a re-review after a COMPLETED round never reaches — `assessResume` checks the report's existence (`no-report`) before it compares heads, and Step 9's cleanup deleted that report — and its "gained commits" wording also misdescribed a rebase or force-push, which lands on the same SHA inequality. The guidance now covers the re-review family (`head-moved`, `no-report`, `worktree-gone`) with cause-appropriate wording ("new or rewritten commits", delta scoping conditional on the anchor surviving), and the restart-cost sentence stays with `head-moved` alone, the only reason `recordRestart` runs for. **R1-4** asked for the guidance to stay OFF `no-report`, contradicting R1-3's ask to put it ON; the resolution is the family split above — present where the fresh run really is a re-review, absent for interruption-state refusals (`diff-hash-mismatch`, `worktree-dirty`, …), with positive AND negative pins so dropping the gate goes red. **R1-5:** a bare count inside a sentence ("review the last 3 commits --comment") is indistinguishable from a PR id at the classifier, and the promotion also flips `--comment` from ignored to effective — the write gate then authorises posting to a PR the user never named. The parser now warns when a bare number is promoted with non-PR tokens AFTER it in the original order (the mid-sentence shape; the canonical number-at-end rescue stays silent), and the clause treats that warning as ask-before-running, never posting silently.
+
+The sandboxed CI round and the second local verification round (head `a73c62d94a`) then proved the warning was disclosure, not a fix, and measured four more gaps. **R2-1 (Critical) — a positional guess granted a public write:** `--comment the 2 follow-ups to 15998` promotes the count "2" to PR #2, `comment.effective` flips true, and the write gate — re-parsing the same record — authorises posting to a PR the sentence never named; the sentence-final count (`review the last 3 --comment`) promoted silently, and the `review.comment` setting needed no flag at all. One warning per word order cannot enumerate prose. The fix withdraws the authority instead: `comment.effective` is false whenever the PR target is a promoted bare number (`promotedNumberTarget` marks the verdict), so the gate refuses with a promotion-specific cause; an explicitly typed number or a PR URL keeps its authority, and a non-posting re-review on the promoted target may still run. **R2-2:** the warning moved after the URL preference, decided from the token that actually became the target and fired exactly when the promotion withheld a requested posting authority — a demoted number never draws it, and a courtesy particle after an unposted re-review costs no confirmation. **R2-3:** the routing guard keyed on "no classifiable target" excluded the only input it exists for — prose parses to a file target indistinguishable from a path — so the clause now judges by what the user SPELLED (no bare integer, no URL, no path-shaped token), the local-intent move is executable (ask or re-invoke bare; prose never parses to local), and the hash form has an operational resolution. **R2-4:** a PR number carrying the sentence's trailing punctuation (`6711。`) was not PR-shaped; classification now normalises trailing sentence marks for the integer test only, keeping the original spelling in extras and warnings. **R1-2/R1-3 (fix-induced):** `worktree-gone` requires a SURVIVING report — it is an interrupted attempt that lost its tree, not a completed round's cleanup — so the docs and the stderr give it its own cause-neutral sentence; the no-report wording asserts no cause (first-ever resume and corrupt reports reach it too); every arm carries the anchor condition; the restart-cost sentence prints where `recordRestart` actually runs, in the past tense; and the ruling promise is scoped to high/medium (low reads no ledger). The worktree-gone arm and the reverse-order malformed-URL cell gained the positive pins whose absence let mutants survive.

+**Route conversational intent, guarded by the parser.** A request like "有更新了，重新评审" / "re-review after the update" is intent, not arguments: it carries no target the parser could classify, and the parser will not refuse it — every non-flag, non-number, non-URL token classifies as a FILE target, so prose ALONE becomes a file path and the round dies capturing the user's sentence — the live half this clause exists for. Before the PR-shape preference in parse-args, prose typed beside a PR number also arrived first and stole the target while the number was demoted to `extraTokens`; that half is closed by the parser, and this paragraph must not be read as describing current behavior (measured; DESIGN.md — The prose re-review request). Resolution is for requests to review a PULL REQUEST again, and it is guarded, not free: run the parser on the verbatim input first, and resolve only when the input is such a request and spells no target of its own — no bare integer (with or without trailing sentence punctuation), no PR/CR URL, and no path-shaped token (`./x`, `../x`, an absolute path, or a token that exists on disk). Judge by what the user SPELLED, not by the verdict's target type: the parser's fallback file verdict over a sentence is prose, not a target — that fallback is exactly the shape this clause rescues, and a model that skips resolution because "the verdict is a file path" re-creates the incident. Three shapes never reach resolution: a bare `/review` with no arguments is a local review (the empty-stdin rule below owns it); an option-only invocation — flags and their values alone, like `/review --fix` or `/review --effort low` — is a supported local review the parser owns verbatim; and the mechanical guard — when the original verdict has `fix.effective: true`, the input is a local-write invocation whatever its prose says ("review my local changes --fix" is the measured shape), so ask which target the user means or re-invoke the local review bare (`/review --fix`), and never resolve a PR into it: `--fix` is effective only on a non-PR target, and resolution would disarm it. Prose that asks for a LOCAL review is not re-review intent even without `--fix` — ask, or re-invoke `/review` bare; prose never parses to a local target, so "run it as parsed" is not a move available here. When the verdict marks the target as a promoted bare number (`promotedNumberTarget`), confirm the target with the user before running — a count may be wearing a PR id's shape — and never post on it silently. When resolution does apply, resolve the target from the conversation (the PR this session last reviewed), announce the resolution in the output language, and run the parser on the resolved invocation — the target plus any flags the input already carries: write that invocation to a file of your own under `.qwen/tmp/`, keep the CLI's args file untouched (it is the record of what was asked), pipe your file to the parser, remove it once the parser has read it (no Step 9 sweep knows that name), and say you did. The resolved target is a number or URL the conversation explicitly names — copy it, do not reconstruct it; a `#` prefix is reference decoration, not part of the target, so an input like `/review #15998` names PR 15998: resolve to the bare number (or ask for it) — the parser deliberately leaves the hash form non-PR-shaped. This is the one sanctioned departure from the copy-verbatim rule below, and it is narrow: verbatim governs the arguments the user gave FOR a review, and any input already carrying a number, URL, or path goes to the parser untouched. When the conversation names no unique PR, ask which one — never guess, and never review the prose as a file path. **Posting is the resolution's hard boundary.** Step 7's write gate re-parses the CLI's verbatim record on purpose — a model-written resolution is not an authorization source — so a prose record cannot authorise posting even when the resolved invocation carries `--comment`. The parser itself enforces the sharpest edge of this: a promoted bare number never carries posting authority (`comment.effective` stays false and `promotedNumberTarget` marks the verdict), because a positional guess must never grant a public write. Read the verdict after parsing: when `comment.effective` is true (the request carries `--comment`, or the `review.comment` setting is on), do not run a review whose submission is already refused — present the resolved invocation (e.g. `/review <n> --comment`) and ask the user to re-invoke it explicitly; that invocation's record authorises normally. When the request asked for comments but the verdict withholds them (a promoted number, or a prose record), say so and present the same explicit invocation. A non-posting re-review runs end-to-end on the resolved target. A re-review after new commits is a plain run: at high effort the incremental check below scopes the delta (lower efforts review the full diff), and `--resume` is never the flag for it — that continues an interrupted run at an UNMOVED head.
+
 **Do not parse the arguments yourself — run the parser. And do not retype them — they are already in a file.** The flag grammar (`--comment`, `--effort <level>`, `--effort=<level>`) and the target disambiguation are deterministic, and three separate parsing bugs shipped while they lived here as prose. The tested implementation is a subcommand, and it reads the argument string **on stdin from a file — never as a positional shell argument, and never inline in shell syntax**: a raw string that begins with a flag (`/review --effort low`) is eaten by the CLI's own argument parsing before the subcommand runs (`Unknown argument: effort low`); one containing a quote or `$(...)` is mangled by the shell; and a heredoc is not safe either — the delimiter is recognized inside the content, so a raw string carrying that exact line would terminate the heredoc early and hand the rest to the shell as commands. A file crosses the boundary with zero shell parsing of the content.
 
 **The CLI has already written that file for you.** When `/review` is invoked with arguments, they are saved verbatim to a session-private file before this prompt reaches you, and the `<skill-args>` note at the end of your instructions gives you its **exact path** — it is under `.qwen/tmp/s-<session>/`, so do not guess the name, read the path the note states. Read from that file. Do **not** `write_file` the arguments yourself: that is a transcription, and a transcription is a recall. A transcribed argument has already turned a PR review into a silent no-op (measured; DESIGN.md — The transcribed argument file).

 - `target` — `{type: "pr-number", number}` | `{type: "pr-url", url, host, owner, repo, number}` | `{type: "file", path}` | `{type: "local"}`. A `pr-url` arrives validated and canonicalized (scheme/host lowercased, query and fragment dropped, the number required to end its path segment — `/pull/42oops` is not PR 42) with host/owner/repo/number extracted; do not re-classify tokens by hand. A token that merely looks like a URL is refused with a warning and reported in `extraTokens`, never guessed into a target.
 - `effort` + `effortSource` — the resolved level after remembered/configured defaults (**high** for PR targets, **medium** for local/file) and the `--comment` override (an **effective** `--comment` forces `high`; an ignored one on a non-PR target changes nothing). `last_used` means the project reused the last level the user explicitly typed, and it outranks `review.effort`. Two `settings.json` keys feed the configured defaults: `review.effort` replaces the built-in target default when neither an explicit nor remembered level applies (`effortSource: "configured"`), and `review.comment: true` makes every PR review behave as if `--comment` was passed — the forcings above still apply. Both resolve from operator scopes only (system/user); a repository's `.qwen/settings.json` cannot set them. Do not re-derive it.
-- `comment.requested` / `comment.effective` — `effective` is what gates Step 7 (true also when only the `review.comment` setting is on); `requested && !effective` means the user asked on a non-PR target, and the warning for that is already in `warnings`.
+- `comment.requested` / `comment.effective` — `effective` is what gates Step 7 (true also when only the `review.comment` setting is on); `requested && !effective` means the user asked on a non-PR target, used `--topology minimal`, or requested posting on a PR target whose bare number was promoted from prose, and the warning for the actual cause is already in `warnings`.
 - `fix.requested` / `fix.effective` — `--fix` is `--comment` reflected, and gated on the opposite target. `--comment` writes to a **pull request**, so it needs one; `--fix` writes to a **working tree**, so it needs one that outlives the review. A PR review's tree is the ephemeral worktree `fetch-pr` creates and Step 9 deletes, so `--fix` on a PR target is ignored with a warning — edits there are discarded minutes later, and reporting findings as "fixed" into a directory that no longer exists is worse than not fixing them. `effective` is what gates Step 6B. An effective `--fix` also floors the effort at **medium**: it edits the user's files, and low runs no verification, so applying an unverified finding is the same mistake as posting one, aimed at their working tree instead of a pull request. It does not force **high** — medium's findings are verified, and the reverse audit high adds hunts for findings that are _missing_, which is not what deciding whether to apply one turns on.
 - `severityFloor` + `severityFloorSource` — the posting floor for a PR review: `critical` posts only Criticals (otherwise-postable high-confidence Suggestions are recorded and deferred — Step 6's convergence posture — and so is the one Critical shape the floor defers by its axes, fails-closed on new surface; low-confidence and Nice-to-have findings stay terminal-only as ever), `suggestion` posts Criticals and Suggestions at every round, and `auto` — the default — is the **round-adaptive rule you resolve in Step 6**, where the round is known: `suggestion` through round 5, `critical` from round 6 — **or `critical` from any round once the recovered ledger's `flatRounds` streak has reached its bar** (Step 6's signal-driven trigger: the first-time-finding rate has not fallen for that many consecutive rounds, so the loop is re-deriving the same set and the floor stems it early). The parser cannot resolve `auto` itself (the round comes from the previous posted round's ledger, not fetched yet), so carry the verdict's value forward and resolve it there. Explicit flag beats the `review.severityFloor` setting beats `auto`; a non-PR target has no rounds, so the flag warns and is ignored there. The floor governs what the review **posts**, never what it finds, verifies, or reports in the terminal.
 - `topology` + `topologySource` — the shape of the run. `auto` (the default) runs the standing effort-driven pipeline described below. `minimal` runs the single-pass A/B comparison arm (Step 3M) instead — and when it is set, it OVERRIDES the effort dispatch entirely. In this step you run `parse-args` and the **diff capture only** (`fetch-pr` for a same-repo PR, the lightweight `fetch-diff` for a cross-repo PR, or the local capture for a local/file target — exactly as below), then jump straight to **Step 3M**. You SKIP the rest of Step 1's setup — the rules load, `pr-context`, `comment-status`, and the incremental-cache check — and you skip the fan-out, verification, reverse audit, and posting. `minimal` is terminal-only; the parser has already forced `comment.effective`, `fix.effective`, and `resume.effective` to false, and its warnings for that are in `warnings`. There is no configured topology — it is only ever an explicit flag.
-- `resume.requested` / `resume.effective` — `--resume` continues an interrupted run of the same PR instead of starting over. `effective` is what gates the resume branch below, and it is a TARGET-SHAPE gate rather than a promise: a cross-repo `pr-url` with no matching remote is `effective: true` but routes to lightweight mode, which never calls `fetch-pr` — item 3 below owns telling the user the flag is inert there. `requested && !effective` means a local or file target, or `--topology minimal` (a fresh single pass neither continues nor consumes an interrupted run), already warned in `warnings`. The resolved effort source controls continuity: a target default is omitted so the interrupted run stays pinned to its recorded level; an explicit, remembered, configured, or comment-forced level is passed through, and a mismatch makes `fetch-pr` refuse the resume and run fresh at that required level.

On a round the capture resolved to the **critical posting posture** the report also carries `incremental.posture: "critical"` with its `postureCause` (`round`, `flat-trend`, or `explicit` — the same facts Step 6's floor resolution reads, predicted from the side file and the CLI-recorded invocation), and the round runs the **fix-audit shape**: see Step 1's topology note and Step 5's posture narrowing. **Also read the cache's `findings` ledger** (older caches have none — then there is nothing to track): these are the previous round's findings with their ids, and Step 6 owes each of them a ruling this round. (Reachable only under a matching identity: the gate inside the command is what keeps a cross-model anchor from scoping anything.)
     - `upToDate: true` **and** `comment.effective` is false (no `--comment` flag, and `review.comment` not enabled in settings) → inform the user "No new changes since last review" (this branch consumes no plan, so it holds even when `diffPath` is null). **Before the cleanup, write the stop sidecar** so `qwen review run` reads the round as DECIDED instead of exiting 1 "Review did not complete" over it: when the environment carries `QWEN_REVIEW_RUN_ID`, write `.qwen/tmp/qwen-review-pr-<n>-stop.json` containing exactly `{"reason": "<up-to-date|empty-diff>", "runId": "<the QWEN_REVIEW_RUN_ID value>"}` — the same reason+runId contract `capture-local` writes for local stops, runId copied verbatim (the parent's reader is nonce-fenced and discards any other stamp); without that variable no parent is reading and the file is not written. `cleanup` deliberately KEEPS this run's sidecar (it spares a `stop.json` whose `runId` matches the environment) so the parent can still read the decision after the child exits — do not remove it by hand; the next run's cleanup collects it. Then run `"${QWEN_CODE_CLI:-qwen}" review cleanup pr-<n>` to remove the worktree just created, and stop. **This branch does not apply on a resumed run** (`resumed: true` from the resume branch below): a continuation's `incremental` field is the interrupted attempt's history, not this run's decision, and taking the stop/cleanup here would destroy the very state `--resume` reused.
     - `upToDate: true` **but** `comment.effective` is true (the `--comment` flag or the `review.comment` setting) → run the full review anyway — the report already holds the full-range diff and plan for exactly this flow, unless `diffPath` is null, which is the ordinary degraded state (partial coverage, disclosed) rather than a scoping fact. Inform the user: "No new code changes. Running review to post inline comments."
     - `reason: cross-model-anchor` → the cached anchor was certified by another identity, so it was not used. Continue on the full-range plan (or, when `diffPath` is null, on the degraded state its siblings name). The command already said which identity certified it and which is running; repeat that to the user rather than restating it from the cache.
     - `effective: false` → the anchor was refused and the report says why. **Every reason names a CAUSE** — `not-an-ancestor` (a rebase or force-push); `unknown-commit`; `behind-merge-base` (the base moved past the anchor, e.g. a partial merge landed, and scoping to it would review base history the PR does not contain); `nothing-to-narrow` (the narrowing found nothing it could publish — all deterministic and all safe, because the round keeps the full range: an ordinary "undo per feedback" revert that puts lines back the way the base had them, so the PR's own diff no longer displays the undone FILE at all (a file the PR still displays does not refuse — the join fails closed and publishes its section whole instead); a capture on either side whose bytes do not survive a UTF-8 round trip; a delta the parser cannot read; and a fail-closed refusal where the two captures key the same change differently — a path or a rename git resolves differently across the two ranges — so narrowing would drop a change the PR's diff displays); `base-untrusted` (the base could not be fetched, so the clamp that keeps an anchor from scoping wider than the PR's diff could not be ruled); `capture-failed` (a capture threw, or the base fetch or merge-base resolution failed); `partition-failed` (the diff would not tile). **Whether a PLAN exists is a separate field: `diffPath`.** Non-null → the diff and plan are the full range; continue as a full review. Null → no diff exists at all: that is the `diffPath: null` degraded state (partial coverage, disclosed), whatever the reason says. Do not read one field for both facts — a reason that meant "planless" as well as "why" is what put deterministic refusals into the retry class below. The previous round's ledger is still owed its rulings in every refusal.
 
-  - **When the cache has no anchor, the PR itself carries one** (high effort only, same as the cache). The file being absent is the NORMAL state everywhere except the machine that ran the last review — CI, another clone, a colleague's checkout — and it used to mean the incremental range silently degraded to the full diff every time, which is precisely the cost incremental review exists to avoid. The anchor now rides the posted review: the machine ledger's marker carries `sha`, the head the last clean round reviewed, and `pr-context` writes it into the side file `qwen-review-pr-<n>-prev-ledger.json` with the rest of the ledger. So when the cache had no anchor to pass — including the case where it HELD one that the cache-path gate withheld, because `lastModelId` was another model's: the marker may carry an anchor THIS model certified, and a round that stops at the cache would never look — **or the anchor it passed was refused** (`incremental.effective: false` — a rebase or force-push retires a cached anchor exactly when another environment may have posted a newer round whose marker still holds a valid one): proceed with the setup batch as usual, and when the side file lands with a `sha` — **different from the one already refused, OR the same sha when the refusal was infrastructure** (`base-untrusted`, `capture-failed`: the anchor was never ruled invalid, and the component that failed — a base fetch, a merge-base resolution, a capture — is re-run by the re-run. One shape of `capture-failed` retries ONCE, not forever: a base-less refusal (a null `mergeBaseSha`) means the base fetch failed (`baseFetchFailed: true`) and no local base ref remained, or `git merge-base` itself failed on a non-answer exit. The failed component IS re-run by the re-run, but the exit status cannot split the members — git exits 128 identically for a transient fetch fault and for a deterministic refusal (the base branch deleted on the remote — the refspec fetch fails every time), and the merge-base probe folds its surface failures the same way — so a second refusal of the same shape on the same sha is the deterministic member. Retry that one, once. Every other reason is deterministic for the same sha and must NOT be retried: a validity refusal re-refuses; a planless `partition-failed` always carries a `mergeBaseSha` — with no base nothing is captured and an empty diff cannot fail to tile — so both ranges were in hand and both refused to tile, which the re-run reproduces exactly, do not retry it; `nothing-to-narrow` re-narrows identically: the same two captures select the same hunks, and a capture that failed a UTF-8 round trip fails it again — and its base-less shape (a null `mergeBaseSha` with `baseFetchFailed: false`) is NOT retryable: the fetch succeeded and `git merge-base` found no common ancestor at all (a cross-fork PR with unrelated history), which a re-run reproduces exactly) —, **re-run the `fetch-pr` command from above with `--since <sha>` — REPLACING any `--since` it already carries, never appending a second one** (a repeated flag is one flag with two values; the CLI takes the last, but a command that reads as two anchors is a command nobody can check) — the PR ref is already fetched so the re-run is cheap, and it rebuilds the worktree, diff and chunk plan scoped to the delta, with the validation the old flow asked you to hand-run (`cat-file`, `merge-base --is-ancestor`) inside the command where it cannot be skipped. Then act on the new report's `incremental` field exactly as the cache path above does (**the same-model gate on this path is RULED FOR YOU, not left to you to apply**: the marker carries `model` beside its `sha` — the identity that certified the range — and `pr-context`'s ledger section states the verdict outright, either "the same-model contract HOLDS" or "**Do NOT pass the anchor above as `--since`**". Obey that sentence and do not compare the two identities yourself: the marker's `model` is a PROVIDER-QUALIFIED identity (`<model>@<digest>`) while `{{model}}` above is the bare model id, so they are not the same kind of string — comparing them by hand either never matches, which throws away this whole recovery path, or matches loosely, which accepts another provider's same-named model and scopes past code it never reviewed. A ledger section that states no verdict — because the side file survived from an earlier round the recovery could not re-vouch — is a mismatch: review the full range. The ledger's round is used only for precedence, and an `upToDate` anchor from the side file stops only when `comment.effective` is false **and the side file carries no `anchorFromRound`** — a grafted anchor that resolves to the head means the round it was carried for closed at a head its source had already certified, so `sha..HEAD` re-covers nothing, and the stop would abandon that round's owed work list without a ruling, with every later round at the same head repeating the same stop: proceed instead as when `comment.effective` is true (the re-run report already holds the full-range diff and plan) and rule every ledger entry). The decision lands AFTER the setup batch but BEFORE any agent launches, which is where the money is (a same-SHA stop still runs `cleanup`; it just fires three cheap commands later than the cache's fast path would have). An anchor that fails validation falls back to the full diff with the reason in the report, exactly as a rebased cache sha does. Two edges, both decided for you: if the side file's `round` is **higher** than the cache's, prefer the side file's sha — the cache is stale by a round some other environment posted; and a side file with no `sha` field means no anchor is recoverable. When the last posted round was fail-closed (`compose-review` withholds the anchor then — Step 8 names the conditions) and its work list survived whole, `pr-context` grafts the anchor forward from the most recent EARLIER own marker that carries one — the withhold is about the fail-closed round's own range, while the earlier round's "clean up to `sha`" stays true, and scoping `sha..HEAD` re-covers the gap (the ledger section says "anchoring at", never "reviewed at", when the anchor was carried forward this way, and names the round it was carried from). So a missing `sha` means a shape the graft refuses or cannot reach — the winning work list was truncated by the marker's size caps (a partial work list must not certify a range — the dropped entries would fall outside the grafted scope and retire silently), the only anchored own marker is the winner's own round (one round cannot both certify and withhold), the winner ran at the same head the candidate sha certifies (grafting it would hand Step 1 a same-sha stop that abandons the work list the winner still owes), every own round on the PR closed without an anchor, the only markers are other accounts' (the sha never crosses accounts), or the markers predate the field — and the review is full-range. (The side file may also carry `commitId` — the previous review's own `commit_id`. That is Step 6's **age reference** for the convergence posture, present even on fail-closed rounds; it is never an anchor, and scoping the diff to it would skip exactly the range a fail-closed round could not certify.)

   - **Resuming an interrupted run (`--resume`)**: when `parse-args` reported `resume.effective: true`, append `--resume` to the `fetch-pr` command above (when the plan's wall is the clock — not under the environment's epoch — `fetch-pr` then notes on stderr how much of that wall this continuation has left, or that it has run out, and which builds the gates will now refuse — information about the run ahead, not an instruction: never drop `--resume` or add `--deadline` over it), and decide `--effort` off `effortSource`, not off whether the word `--effort` was typed. Pass the resolved level whenever `effortSource` is `explicit`, `last_used`, `configured`, or `forced-by-comment` (the `--comment` flag or the `review.comment` setting forces high — parse-args announces "running at high effort"); omit it ONLY when `effortSource` is `default`. `fetch-pr` cannot tell a passed-through default from a chosen level: the interrupted run may have recorded a different one, and handing it the resolved default refuses the resume (`effort-mismatch`) whose fresh fall-through discards the very state `--resume` exists to save — blaming an effort nobody asked for. Omitted, the continuation pins to the recorded level. A level this invocation actually requires — a user's explicit `--effort`, the project's remembered level, a configured `review.effort`, or the high that `--comment` forces — that differs from the recorded one is NOT a passed-through default: pass it, so a mismatch refuses the resume (`effort-mismatch`) and runs fresh at the level this invocation needs. That is right — different effort is different work, and posting authority raising the required depth is different work too, never a silent pin. Omitting a `forced-by-comment` high is the trap: `fetch-pr` has no `--comment` input and reads `requestedEffort` only from `--effort`, so the null would pin the continuation at the recorded sub-high level while `--comment` stays effective — the "effective comment at medium effort" state the medium-tier rules call impossible, posting nothing (medium skips posting) or posting from a pipeline missing the high-only passes the forcing exists to guarantee. `fetch-pr` rules on the interrupted attempt's on-disk state itself (worktree still at `fetchedSha` and clean, diff bytes unchanged, PR head unmoved, the same model identity running — `model-mismatch` otherwise — and resume cap unspent — every probe is a fact it gathers, none is yours to assert) and prints one JSON line on stdout. Branch on it:
     - **`{"resumed": true, ...}`** — this run continues the interrupted one. The report at the `--out` path is the PREVIOUS attempt's, deliberately left untouched (its mtime is the run epoch every downstream fence keys on); read it for the worktree, plan and diff, which are all reused. The report's `incremental` field is now HISTORY, not a decision to re-take: a resumed run proceeds on the reused plan and does NOT re-enter the incremental check above — in particular it never takes the `upToDate: true` stop/cleanup branch, which runs `cleanup pr-<n>` and would destroy the exact worktree and lease `--resume` just saved (the interrupted attempt was a `--comment` full review of an up-to-date PR; resuming it without `--comment` effective in THIS invocation would otherwise route it straight into "No new changes since last review" and abandon it).

 The first stable Tauri release may set `electron_bridge=true` to publish the macOS ZIPs and DMGs, Windows NSIS installer, x64 Linux AppImage, and their Electron `0.0.5` manifests. Leave the input disabled for later releases; the fixed `desktop-latest` release retains the bridge assets while `desktop-latest.json` advances independently.
 
+### Linux AppImage dependencies
+
+The AppImage bundles WebKitGTK and its application libraries, but it deliberately relies on the host for the baseline libraries in the [AppImage excludelist](https://github.com/AppImageCommunity/pkg2appimage/blob/master/excludelist): glibc and the C++ runtime, the OpenGL/DRM drivers, X11/xcb, fontconfig/freetype/harfbuzz, zlib, and their low-level dependencies. Bundling those copies breaks against the host's graphics drivers or ABI. Install the distribution packages for the GTK/WebKit stack when using the AppImage.
+
+The release smoke test extracts the AppImage, reads every ELF file's `DT_NEEDED` entries, and fails on any dependency that is neither inside the image nor on that host baseline list. A newly missing application library therefore blocks publication instead of surfacing as a runtime failure.
+
 The macOS workflow accepts either the Tauri-era `APPLE_*` certificate and notarization secrets or the existing `MAC_CSC_*` and `APPLE_NOTARY_*` secrets. `TAURI_SIGNING_PRIVATE_KEY` must match the public key in `src-tauri/tauri.conf.json`.

+Embedding imports `ManagedAgentConfiguration`; internal callbacks additionally import `ManagedAgentInternalConfiguration`. The standalone application also enables the public web configuration. Add the ordinary server artifact as the dependency; Maven resolves the shared modules transitively. All five backend providers are optional runtime dependencies: an embedding host must explicitly add its chosen `com.alibaba:qwen-managed-agent-runtime-{local,ssh,kubernetes,external,static}` coordinates at the same version. Maven still resolves all five when building the standalone server, but does not propagate them to library consumers. The verification module is never installed or deployed. The standalone application YAML is excluded from the ordinary library JAR.
+
+Runtime factories are discovered through `META-INF/services/com.alibaba.qwen.code.runtimebroker.spi.RuntimeProviderFactory`. The default executable and operator artifacts include all five backend JARs. A library host can omit all backends when its Broker is disabled, or select a single provider. `runtime-broker.provisioner` supports `local-process`, `ssh-process`, `kubernetes-workspace`, `external-scratch`, `external-workspace` and `static`; existing built-in settings and persisted identities are unchanged. Only the selected factory validates its configuration and creates resources. Missing providers and duplicate kinds fail explicitly.
+
+Backend selection for embedding is ordinary Maven dependency selection. For example, a host using Kubernetes adds `qwen-managed-agent-server` and `qwen-managed-agent-runtime-kubernetes` at the same version; no exclusions for Local, SSH, External or Static are needed. A host using Local+SSH adds both corresponding backend artifacts. Packaged availability and enabled configuration are separate: only the configured backend is initialized, with Local+SSH as the supported routing combination. The default standalone and operator artifacts continue to contain every backend. Selective standalone builds and archives are outside this change.
+
+To add a compatible provider, compile its factory against `qwen-managed-agent-contracts`, implement `RuntimeProviderFactory`, register its fully qualified class name in that service file, and add the JAR to the host application's runtime classpath. Select its exact kind with `qwen.managed-agent.runtime-broker.provisioner`; bind additional string settings under `qwen.managed-agent.runtime-broker.provider-options`. For example, a provider that reads `getProviderOptions().get("endpoint")` can receive `qwen.managed-agent.runtime-broker.provider-options.endpoint=https://provider.example`. Factories must have inert constructors; validation is configuration-only, preflight may perform read-only diagnostics, and creation transfers the provider's close ownership to the Broker. A remote provider leaves `usesLocalWorkspace()` false. Plugins execute as trusted application code and must honor the existing identity, fencing and Runtime HTTP contracts. This supports classpath selection at startup; existing warmup behavior remains, with no live JAR reload or automatic download.
+
+The provider boundaries and acceptance criteria are in the [backend module design](../../docs/design/2026-10-31-managed-runtime-backend-modules.md).
 
 Server configuration accessors use Lombok through the server POM's annotation processor; enable annotation processing when compiling through an IDE. Keep accessors with normalization, copying or fallback logic explicit. Lombok is excluded from executable and maintenance JARs and is not a runtime dependency of embedding applications.
