Summary

实现 openspec/changes/persist-thread-watches:

  • watch 记录持久化(新增 delegation-watch-store.ts),Host Runtime 重启后自动恢复观察和投递。
  • 被 Runtime 重启打断的 Turn 报告为 interrupted,而不是 completed(d5ab154)。
  • 更新 docs/architecture/thread-watch.md。

分支 HEAD:efa0ad5。

堆叠关系和合并顺序

Closes #720

Test plan

真实环境验收是在较早的 PR 2 分支提交 cf0877d 上做的(2026-11-03,包含 f814137,不包含 d5ab154):

  • 环境:macOS 27.0.1(26A434),Apple M1 Pro;Codex Desktop(ChatGPT.app)26.1027.61615(build 24141);node v22.23.2 / npm 11.21.0;workspace 0.17.0。
  • 通过:重启 Host Runtime 后 watch 被恢复,通知恰好投递 1 次。
  • 发现的问题:重启会终止正在运行的子 Turn,但 watch 事件的 outcome 是 completed(cursor-cli 和 claude-code 都能复现)。d5ab154 就是修这个问题,改为报告 interrupted。
  • 未验证:d5ab154 还没有在真实 Desktop 里复验;codex harness 本身额度用完,没有用它做这项验收。
  • 新增测试文件:packages/host-runtime/test/delegation-watch-restart.test.ts、packages/host-runtime/test/delegation-watch-store.test.ts,以 CI 结果为准。
  • 按 GitHub compare,分支落后 main 5 个 commit,这 5 个 commit 没有改到本 PR 的任何文件。

Add four OpenSpec changes:
- persist-thread-watches: watches survive a Host Runtime restart
- add-external-client-access: named clients, local listener, refs,
  event log with SSE and long-poll, MCP tools
- add-remote-client-access: scopes, tailnet and Funnel access, OAuth
  pairing, webhook adapters (Grok Bot first)
- add-local-design-preview: open local HTML in the built-in browser
  with live reload

Cap the post-restart grace at 5 minutes, hold restored notifications
until the notified Thread is reachable, and state that several Runtimes
sharing a data directory each own their watches and adopt only those
left by exited processes.

Watches were held only in Host Runtime memory, so a restart during a
long delegated stage silently dropped the notification that should wake
the parent Thread.

- Store each watch as a private per-watch record owned by the Runtime
  process; a starting Runtime adopts records of exited processes,
  claiming each with an atomic rename so only one Runtime takes it.
- Deadlines are absolute; restored watches wait up to 5 minutes for
  their sessions before read failures count, and restored notifications
  wait until the notified Thread is readable.
- A send is recorded as in progress before it starts, so a restart
  during the send delivers again (at least once across restarts). An
  unknown outcome while the Runtime runs is still not retried.

Claude-Session: https://claude.ai/code/session_01B9eUbyUAx81Drvbh5AWQEG
Acceptance on macOS showed that restarting the Host Runtime ends the
Harness processes it owns, and the Turn that was running then reads as
completed, so a restored watch told the parent the work was done.

The watch now records the Turn it last saw running (persisted when it
changes). After a restart, if the first read shows that same Turn as
terminal, the notification reports interrupted and says the restart
ended it. A later Turn, or the same Turn still running, is reported as
before. A Turn held by a long-running remote listener that genuinely
finished during the downtime is also reported as interrupted; the
notified side reads the Thread before acting either way.

Also log how many watches a Runtime restored.

Summary

Summary by CodeRabbit

  • 新功能
    • Thread 观察会在 Host Runtime 重启后自动恢复,无需重新注册;观察期限按绝对时间计算,停机时间也计入。
    • 恢复时会等待会话重新就绪;重启前仍在运行的 Turn 若无法恢复,会报告为中断。
    • Runtime 在通知投递过程中重启后会再次尝试投递,因此通知可能重复。观察记录仅当前操作系统用户可读写。
    • 首次保存观察失败时,不会保留未持久化的观察;委派仍会完成,并在结果中说明观察未注册及原因。
  • 文档
    • 更新了 Thread 观察帮助说明,补充重启恢复、中断状态及通知重试行为。

本 PR 实现 Thread Watch 文件持久化与 Runtime 重启恢复,并新增外部客户端访问、远程客户端访问和本地设计预览的 OpenSpec 提案与规范。

Merge Risk: Moderate · up to d21e7

Watch persistence and restart recovery mostly work, but a failed first save can leave an orphan record that later sends a notification, and a clock jump can cause two Runtimes to take over the same watch. Restart explanations are also lost after a second restart. Several spec and design inconsistencies in the added proposals are still open. Resolve or explicitly accept these before merging.

Explanation

依据:整体 PR(merge base 78106589 至 head d21e707)的变更摘要,以及 head 源码 packages/host-runtime/src/delegation-watch.ts 的读取结果。直接关联 Issue 为 #720(open)。本次评估不再引用 Desktop 人工验收,因其不属于编码要求。

  • 持久化 watch 记录 [#720]:FileDelegationWatchStore 位于 delegation-watch-store.ts。DelegationWatchService.watch() 在注册前调用 #persist。写入失败时,该方法撤销内存中的 watch 并抛出 INTERNAL_ERROR。该行为由 d21e707 新增,已在 head 源码中确认。
  • 重启后恢复观察与投递 [#720]:构造函数在存储存在时调用 #restore(),经 store.adopt() 读取记录并加入内存列表。
  • 绝对期限 [#720]:PersistedWatch.deadline 保存注册时的绝对时间。#restore() 不重算期限,因此停机时间计入期限。
  • 重新注册宽限 [#720]:恢复的 watching 记录设置 observeGraceUntil。宽限内的读取失败返回 undefined,不计入 unreadable。恢复的待投递记录设置 deliverGraceUntil。投递判定代码位于截断部分,本次未逐行确认其用法。
  • 停机时投递中断后重投 [#720]:#deliver() 在发送前设置 delivering 并持久化。#restore() 删除 delivering,待投递记录保持 pendingDelivery,因此恢复后会再次投递。该行为符合“至少一次、重复无害”的要求。
  • 运行期未知结果规则不变 [#720]:deliveryFailure() 对未知结果返回 unknown。#deliver() 将其标记为 undeliverable 且不重试。
  • 重启前 Turn 报告为 interrupted(PR 目标,非 #720 原文):#observe() 对重启前运行、恢复后首次读取已终态的 Thread,以及宽限后仍无法打开的 Thread,报告 interrupted 并附重启说明。

未确认项:本次未执行测试,也未取得 CI 结果。新增测试文件 delegation-watch-restart.test.ts、delegation-watch-store.test.ts 和 delegation-watch-store-race.test.ts 在 head 中存在,但其通过情况未经验证。PR 描述中的旧说明称本 PR 仅含 10 个文件。整体 diff 已包含 efa0ad5、0c14480 和 d21e707 的改动,PR 描述已过期。

Full details: Out of Scope Changes check

Explanation

与 #720 直接对应的变更包括:delegation-watch-store.ts、delegation-watch.ts、delegation-control-registry.ts、run-host-runtime.ts、delegation-cli-help.ts、docs/architecture/thread-watch.md、openspec/changes/persist-thread-watches/** 及三个 watch 相关测试文件。这些变更属于 #720 范围。

以下变更出现在整体 PR diff 中(merge base 78106589 至 head d21e707),且与 #720 无关:

  • openspec/changes/add-local-design-preview/**:已在整体 diff 中确认。proposal.md 为新增文件,描述 codexhost preview open 本地设计预览功能,影响 packages/host-runtime 的预览服务器与文件监听,不涉及 watch 持久化。
  • openspec/changes/add-external-client-access/**:外部客户端登记、MCP、事件日志等功能。与 watch 持久化无直接关系。
  • openspec/changes/add-remote-client-access/**:tailnet、Funnel、OAuth 与 webhook 等远程访问功能。与 watch 持久化无直接关系。

这些提案来自提案 PR #725 的 20c1d05。PR 描述说明它们属于堆叠关系,建议先合并 #725。该说明不改变 head 上的 diff 结论:这些文件仍由本 PR 引入,且与 #720 的功能没有连接。

未确认项:openspec/changes/add-copilot-native-harness/** 曾出现在 head 目录列表中。本次整体 PR 摘要未列出该目录,因此不将其计为已证实的越界变更。

Resolution

将 openspec/changes/add-local-design-preview/**、openspec/changes/add-external-client-access/** 与 openspec/changes/add-remote-client-access/** 移出本 PR 的 diff。若这些提案需要保留在堆叠中,应在 #725 合并后将本分支 rebase 到 main,使这些路径不再出现在本 PR 的整体 diff 中。保留 openspec/changes/persist-thread-watches/**、watch 持久化源码、测试和 docs/architecture/thread-watch.md。若 openspec/changes/add-copilot-native-harness/** 确实属于整体 PR 的变更,应按同一规则处理。同时更新 PR 描述中关于本 PR 文件范围的说明。

### 5. 事件日志

每个客户端一个追加写的 JSONL 文件,事件标识按客户端单调递增,并把当前最大标识持久化,以免重启后重复使用。保留期默认 7 天,按天分段文件,过期整段删除。写入在 watch 投递路径上完成:被通知方为客户端时,“投递”就是追加一行并 fsync;成功即视为送达,因此客户端 watch 没有忙碌重试。PR 1 的至少一次语义在这里表现为:重启后可能追加内容相同、标识不同的事件,客户端按 Thread 与来源 Turn 去重。

使用 watch 身份对重复事件去重。

同一个 Thread 的 Turn 长时间运行时,客户端可以先后注册两个 watch,并让它们分别超时。两个事件可能具有相同的 Thread 和来源 Turn,或者都没有来源 Turn。按这两个字段去重会丢弃第二次独立通知。

请为每次 watch 分配持久化的唯一标识,并在重启重投时保持该标识不变。客户端应按该标识去重。

如果客户端已读取事件 41,而日志清理后最早保留的事件是 42,after=41 仍可完整读取所有后续事件。当前条件却要求返回 CURSOR_EXPIRED。客户端若改用 after=42,又会跳过事件 42。

保留外部客户端的默认通知目标。

Line 15-16 只允许显式 --notify 或 CODEXHOST_THREAD_ID。外部客户端规范要求经外部监听调用且未提供 --notify 时,通知目标为当前客户端;thread watch <thread> 和客户端 Watch 也依赖此默认值。若实现遵循本文件,外部客户端的默认 Watch 会返回 INVALID_ARGUMENT,并且不会写入事件日志。(raw.githubusercontent.com)

请在本文件加入外部监听调用的客户端分支,并保留 --notify client:<name> 只能指向当前客户端的限制。

明确绝对观察期限与恢复宽限的优先级。

Line 71 要求 Runtime 恢复后,已超过绝对观察期限且 Thread 仍未停止时报告 timedOut。Line 75-76 又要求会话尚未重新注册期间不得报告 timedOut,并延后宽限计算。Runtime 停机时间超过观察期限、恢复后会话仍未注册时,这两条规则会产生相反结果。实现无法同时满足它们。(raw.githubusercontent.com)

请明确会话恢复宽限是否也延迟 timedOut。同时更新绝对期限场景和恢复未就绪场景,避免测试对同一状态要求不同结果。

persisted() 没有保存 endedByRestart。第二次重启后,通知会丢失中断原因。

#tick 在 Line 295 设置 watch.endedByRestart = true。设置后 watch 进入 pendingDelivery 状态,并被持久化。persisted() 不包含 endedByRestart,PersistedWatch 也没有这个字段。

可以这样触发:被通知的 Thread 处于 THREAD_BUSY,等待重试的时间最长可达 6 小时。如果 Runtime 在这段时间内再次重启,恢复后的记录仍是 outcome: "interrupted",但没有 endedByRestart。describe() 于是走默认分支,只输出 interrupted (Turn X).。通知会缺少 “The Host Runtime restarted while this Turn ran …” 这段说明。

父 Thread 会把这种情况误读为用户 Stop 导致的中断。docs/architecture/thread-watch.md Line 69 承诺“报告为 interrupted 并说明原因”,在这种情况下没有兑现。

lastReadError 也有同样的问题:重启后,unreadable 通知会显示为 unknown error。

修复方法:在 PersistedWatch 中加入可选字段 endedByRestart?: boolean,在 persisted() 中写出该字段,并在 parseWatchFile 中校验它的类型为 boolean。

🐛 建议修复(本文件部分)
     deliveryDeadline,
     delivering,
     runningTurnId,
+    endedByRestart,

@@
     ...(delivering ? { delivering } : {}),
     ...(runningTurnId ? { runningTurnId } : {}),
+    ...(endedByRestart ? { endedByRestart } : {}),
   };

delegation-watch-store.ts 需要同步修改:

// PersistedWatch
  /** The terminal Turn was ended by a restart, not by its Harness. */
  endedByRestart?: boolean;

// parseWatchFile
    (watch.endedByRestart !== undefined && typeof watch.endedByRestart !== "boolean") ||

同时删除 Watch 接口中重复声明的 endedByRestart。

更新 persisted()、PersistedWatch 和 parseWatchFile,持久化并校验 endedByRestart
可选布尔字段,确保重启恢复后仍能说明中断原因;同时检查并保留 lastReadError,使 unreadable 通知在重启后不会退化为 unknown
error。移除 Watch 中重复声明的 endedByRestart,并保留现有字段的序列化与解析行为。

The macOS re-test showed the previous check was not enough: claude-code
restored the cut-off Turn under a new Turn id, so it was still reported
completed, and cursor-cli could not reopen the session at all, so the
watch reported notFound after the grace period.

A watch that was observing a running Thread before a restart now
reports interrupted when the first successful read after the restart is
already terminal, whatever the Turn id, and also when the Thread still
cannot be opened once the restore grace ends. The notification says
what happened and what it read as, and the explanation is stored with
the watch so a further restart keeps it. A Thread still running on the
first read is reported normally when it stops. Tracking the running
Turn id is no longer needed and is removed.

统一停机期间的终态结果规则。

若被观察 Thread 在其他 Runtime 中继续运行,并在本 Runtime 停机期间完成,Line 74 要求报告实际终态 completed,这里却要求报告 interrupted。当前实现采用后者,架构文档也明确承认这一例外。请限定 Line 74 的适用条件,或在此处明确该例外,避免同一场景有两项相反的规范要求。(raw.githubusercontent.com)

As per coding guidelines,变更完成时“implementation, contracts, tests, and affected documentation agree”。

处理会话未重新注册时的读取错误。

若恢复宽限期结束后仍没有已注册会话,DelegationControlRegistry.#registrationForThread 抛出 PARENT_THREAD_AMBIGUOUS,并设置 matchingRuntimeCount: 0,而不是抛出 THREAD_NOT_FOUND。因此这个分支不会执行;watch 随后可能报告 unreadable,或在期限已过时报告 timedOut,而非本次变更要求的 interrupted。请在宽限期结束后识别该无会话状态,并为它保存相应的 restartNote。(raw.githubusercontent.com)

macOS 实机验收(2026-11-04)发现:Host Runtime 重启会结束正在运行的子 Turn。claude-code 恢复后换了 Turn id,结果被报成 completed;cursor-cli 恢复后找不到 Thread,结果被报成 notFound。已在 efa0ad5 修复:重启前处于观察中的 Thread,重启后第一次读取若已是终态,或宽限结束后仍无法打开,一律报 interrupted 并说明原因。等待复测。

Windows CI failed "lets only one of two concurrent adopters take a
record": both adopters returned the watch. An adopter read the exited
owner's record, another adopter claimed and re-saved it under its own
owner, and the first adopter's claim rename then took that live record
and adopted it again.

After the claim rename, compare the claimed file with what was read. If
it changed, hand it back with link (which never replaces a newer record)
and skip it. Claim names also get a random suffix so two stores in one
process never share a claim. A new test pauses the claim rename to
reproduce the interleaving deterministically.

packages/host-runtime/src/delegation-watch.ts:198-208
Major · Data Integrity & Integration · Quick win

首次持久化失败时不要返回 watching。

当 FileDelegationWatchStore.save 在写入记录前失败时,#write 会吸收错误。因此,watch() 会返回 state: "watching",但重启后没有记录可以恢复。对于 delegate start --watch,这也会阻止现有的 watchStartedTurn 返回 notRegistered 和失败原因。

让首次注册的持久化失败传播到 watch(),并移除未持久化的内存 watch。后续状态更新继续使用当前的尽力持久化策略。

使用不受墙钟跳变影响的所有者身份。

在 Linux 上,如果两个 Runtime 共用数据目录,且墙钟在它们启动之间跳变,例如 60 秒,ownerAlive() 会因 boot 差值过大而跳过 PID 检查。后启动的 Runtime 可以认领仍在运行的进程的 watch。两个进程随后可能重复投递通知,并覆盖同一记录。

使用不受墙钟调整影响的身份判断,同时保留重启后识别 PID 复用的能力。单纯放宽容差不能处理更大的时钟跳变。

防止首次持久化失败后留下孤立记录。

如果已有定时器运行,#tick 可以在首次持久化等待期间观察新 watch。如果首次写入失败,随后排队的状态保存仍可能成功。调用方会收到 INTERNAL_ERROR,但重启后该记录可能被恢复并发出通知;如果调用方已重试,也可能收到重复通知。

需要阻止失败的 watch 被后续观察操作保存,并清理已排队的保存。仅将 splice 替换为 #remove 不够:正在等待的 #observe 可能在删除排队后才返回并再次保存。

在新增 watch 的首次持久化失败路径中,确保该 watch 不会再被 #tick 或进行中的 #observe 保存,并清理已排队的状态保存;仅从
#watches 删除记录不足以处理 #observe 稍后恢复并再次保存的竞态。更新相关保存与观察流程,建立可靠的失效或同步机制,使清理完成后失败的
watch 无法复活或触发通知。
