When external clients submit more top-level delegations than the local running limit, return their Thread identity immediately with status: queued and start them in FIFO order as slots become free. Existing messages and child delegations continue immediately. The limit is off by default and is synchronized to the local Host from Desktop settings.

Native Codex tasks queue their first Turn inside real Threads created up front. Reads, history, watches, cancellation and restart recovery keep those identities and preserve Threads that a user has already started. Persisted queue adoption is serialized across processes.

Depends on #783 for activity/ancestry tracking. The capacity change is one commit above that dependency; focused diff.

Validation: typecheck, lint, Renderer build, focused Host/queue/Renderer tests, and two Playwright settings tests passed. CI passed on Linux x64, Linux ARM64, macOS and Windows.

Summary

Summary by CodeRabbit

  • 新功能

    • 设置中新增默认关闭的委派并发上限，可将同时运行的顶层线程数设为 1–32。达到上限后，委派按顺序排队，并在有空位时自动启动；队列可在运行时重启后恢复。
    • thread watch 和启用监视的委派支持可选卡住提醒。线程达到设定的静默时长后会发出提醒，但监视继续；活动恢复后，后续静默时段可再次提醒。
    • 排队线程可查看状态和位置、等待、监视或取消；向尚未启动的排队线程发送消息会失败。

  • 文档

    • 补充并发上限、排队行为、恢复规则及卡住提醒的说明。

新增可选的委派并发上限。达到上限时，符合条件的委派按序排队，并可在 Host Runtime 重启后恢复。thread watch 和 delegate start --watch 新增可选静默提醒。Renderer 设置页支持配置并同步容量设置。

Changes: 委派容量与观察行为

Layer / File(s) Summary
容量设置与 Renderer 同步
packages/shared-contracts/*, packages/renderer-extension/src/renderer-*, packages/renderer-extension/src/settings/*, packages/renderer-extension/src/versioned-renderer-adapter.ts, packages/renderer-extension/test/*, tests/e2e/renderer-delegation-capacity.spec.ts		 新增默认关闭、范围为 1–32 且默认值为 4 的容量设置。Renderer 保存偏好并向本机 Host 同步，设置页提供开关、上限输入框和同步状态。
Host 容量队列与排队线程集成
packages/host-runtime/src/delegation-capacity-*, packages/host-runtime/src/delegation-control-registry.ts, packages/host-runtime/src/app-server-host.ts, packages/host-runtime/src/harness-delegation-coordinator.ts, packages/host-runtime/src/delegation-types.ts, packages/host-runtime/src/desktop-thread-routing.ts, packages/host-runtime/src/external-thread-repository.ts, packages/host-runtime/src/run-host-runtime.ts, packages/host-runtime/src/shared-thread-bridge.ts, packages/host-runtime/src/remote-delegation-read.ts		 新增容量准入、FIFO 排队、文件持久化和 Runtime 接管。排队 Thread 支持读取、列表、等待、取消和队列位置查询；排队或创建中的 Thread 不接受发送消息。原生 Codex 排队 Thread 支持恢复及 Turn 接管。
静默提醒与活动跟踪
packages/host-runtime/src/thread-activity.ts, packages/host-runtime/src/delegation-watch.ts, packages/host-runtime/src/delegation-watch-store.ts, packages/host-runtime/src/delegation-control-server.ts, packages/host-runtime/src/external-client-mcp.ts, packages/host-runtime/src/external-client-events.ts		 watch 增加 stallAfterMs 与 stalled 提醒。Host 跟踪 Thread 与已知祖先的活动；达到静默阈值时发送提醒，活动恢复后重新计时，观察继续运行。
CLI、文档与规格
packages/host-runtime/src/delegation-cli*, docs/architecture/*, docs/index.md, openspec/changes/*		 CLI 和外部客户端接口说明新增队列状态、队列位置及静默阈值参数。架构文档和 OpenSpec 文件记录设置、排队、恢复及提醒规则。
测试
packages/host-runtime/test/*delegation-capacity*, packages/host-runtime/test/*watch*, packages/host-runtime/test/thread-activity.test.ts, packages/host-runtime/test/harness-delegation-coordinator.test.ts, packages/host-runtime/test/remote-delegation-read.test.ts, packages/renderer-extension/test/*delegation-capacity*, tests/e2e/renderer-delegation-capacity.spec.ts, tests/e2e/renderer-idle-release.spec.ts		 新增测试覆盖容量准入、队列恢复、原生 Thread 交错、静默提醒、活动传播、Renderer 同步和设置页行为。另删除了一个验证持久化失败时删除原生 Codex Thread 的旧测试。

1814-1826: 这些行已经修复了上一轮评论指出的问题，所以这条评论是重复的。#rewriteOfficialDelegationMentions 抛错时，catch 块会以 rejected 结算认领，排队任务保持可启动。

新代码仍有一个小问题。#claimQueuedOfficialStart 先于 try 执行，并已写入 #pendingQueuedClaims。现有 catch 路径覆盖了认领之后的失败，所以不需要再改动。

1740-1740: LGTM!

# Repository Guidelines

## Testing & Completion

- For core logic or major feature changes, update the corresponding feature document in `docs/`, creating one only when needed. Describe current behavior and key constraints; prefer maintaining an existing document over adding a change report. Minor fixes and local refactors need no documentation changes.

packages/host-runtime/src/delegation-watch.ts: 1

387-400: Low value

需要确认：stalled 提醒记录在投递失败后会被永久保留，且未持久化。

alert 是内存中的 pendingDelivery 记录，#persist 对它直接返回。如果 #deliver 失败且结果为 rejected，记录会一直重试到 deliveryDeadline（6 小时）。在此期间，#tick 每次都会对同一 notifyThreadId 重复调用 #deliver。同时，stallNotified 已设置，所以不会产生重复告警。这个行为本身一致。

但 alert 复制了 persisted(watch)。harnessId 和 refs 在此时才由 #observe 写入 watch，已被复制，没有问题。

建议补充一项测试：stalled 告警在 notifyThreadId 忙碌（THREAD_BUSY）时保持 pending，并在恢复后只投递一次。

取消排队中的原生 Thread 后，应拒绝 thread send。

原生 Thread 即使没有 Turn，Delegation 记录仍会使 #neverStarted 将它视为已被持有。取消后，send 可以继续启动一条新 Turn，而不是按规格返回 THREAD_NOT_FOUND。

当已结束的原生排队 Thread 没有 Turn 时，返回 THREAD_NOT_FOUND。保留原生 Thread，并继续允许已有 Turn 的 Thread 接收后续消息。

Return a queued native start to the queue when rewriting its delegation
