fix(test): wait for interactive PTY sessions to end during cleanup

[qwen-code-dev-bot]

What this PR does

Makes the interactive test harness wait for each terminal session it ends, instead of signalling it and moving on. The rig already remembered every pseudo-terminal child it spawned and terminated the ones a test never closed; it now also blocks until each of those children has actually exited, within a bound that sits above the CLI's own shutdown ceiling so a child that refuses to die cannot hang teardown. The bound's timer leaves nothing behind that would keep the worker's event loop alive.

The regression test that covers this was strengthened in place rather than duplicated. Its stand-in for the CLI now behaves like the real one — it traps the termination signal and exits only after a delay — and it announces that it has finished booting before the harness is allowed to signal it. The test asserts on the wait itself, so it goes red when either half of the guard is removed: the signal, or the wait for it to take effect.

Why it's needed

The E2E Interactive - OpenTUI renderer (bun) leg keeps reddening main without naming a single failing test. It did so in six of the last nine runs, and one of those six was the very commit that landed #10971 to fix it — so that repair narrowed the class but did not close it. The failing step runs just as long as a healthy one, which says the suite completes and the process dies afterwards; and the log carries no failure line at all, which is what makes the detector file per commit instead of per test. A run that passes everything and still exits non-zero is an unhandled error.

#10971 correctly identified the mechanism: a session a test never closed stays alive to the end of the run, still forwarding every terminal byte into the worker's standard output because the same environment enables that verbose forwarding, and once vitest tears the worker down the reader end of that pipe is gone — the next write raises EPIPE, which Node escalates to an uncaught exception. What it missed is that signalling a session is not the same as ending it. The CLI traps the hangup signal for any interactive session, whatever the renderer, and exits only after an asynchronous shutdown chain has drained: chat-recording flush, MCP subprocess stop, telemetry shutdown, session-usage persisting, all bounded by a five-second wall clock. So the harness returned from teardown with the child still alive and still writing, and the window #10971 set out to close stayed open.

Both halves were measured rather than assumed. Against the real bundle, the child is still alive at the instant the kill call returns, and exits 83ms later with exit code 129 — the CLI's own code for a hangup it handled itself. And in a whole-leg run on the parent commit, watching the process table caught a CLI child being reparented to init at the moment its vitest worker exited, which is precisely the instant an EPIPE is fatal rather than harmless; its lifetime and its sibling's line up with the two test durations in the file that starts sessions and never closes them. After this change the same measurement finds no orphans at all, across two whole-leg runs, with an identical set of passing tests.

The reason the earlier witness did not catch this is worth recording, because it is the reason the fix shipped green once already. Its stand-in had no signal handler, so it died instantly on the default action, and it asserted through a poll with a ten-second timeout — a poll that is perfectly happy for the child to outlive teardown by up to ten seconds. The property that actually matters, "gone by the time teardown returns", was never pinned by anything.

Reviewer Test Plan

How to verify

The load-bearing claim is that no interactive session is still alive when teardown returns, and the regression test in the rig's own test file is the whole of it. On this branch it passes in about a second. Check out the parent commit, apply only the test change, and it fails reporting that teardown returned before the child exited — zero milliseconds measured against a 750ms floor. It needs no model credentials, no bun, and no network, because the stand-in is a short script rather than the CLI.

To confirm both halves of the guard are witnessed, delete each in turn and re-run that file. Removing the wait fails on the duration floor. Removing the kill fails on the survival poll, after the bound and the poll have both expired. Restoring either returns it to green.

The wider suite should be unchanged: run the interactive leg and compare against main, expecting the same ten files collected and the same eighteen tests passing with the same two skips, and no new ones. This matters most for the sessions that end by themselves — the Ctrl+C exit case and the mid-turn quit cases — since teardown now waits on children those tests already terminated, and for those the wait resolves immediately because the exit has already been observed.

It is also worth watching the process table while the leg runs, which is how the defect was caught. On main a CLI child outlives its worker and is reparented to init; on this branch none is.

The cost is small and measurable: the wait is each session's real shutdown, 35–42ms in measurement, and the one file that leaks a session grew by 38ms. Whole-leg wall clock is dominated by a live-model compression file whose individual tests swing between 71s and 107s run to run, so compare per-file timings rather than the total when judging whether this change slowed anything.

The OpenTUI leg itself is the final check and needs bun; it could not be run where this change was prepared. Because the failure is intermittent — the leg passed at the commit immediately after the one this issue was filed against, before any of this work — a single green run proves little on its own. The meaningful signal is whether the "exit code 1, no failing test" shape stops recurring over a run of merges.

Evidence (Before & After)

Non-UI change, so no screenshots. The measured before/after is the process table during a whole interactive-leg run:

• Before (parent commit): one CLI child reparented to init — ppid 2130 → 1 — at the last sample of the run, i.e. at worker teardown. Whole-leg result: 9 passed | 1 skipped (10) files, 18 passed | 2 skipped (20) tests, exit 0.
• After (this branch, two separate whole-leg runs): 0 orphans, 0 survivors fifteen seconds after the run. Whole-leg result identical: 9 passed | 1 skipped (10) files, 18 passed | 2 skipped (20) tests, exit 0.
• Direct measurement against the real bundle: alive immediately after kill(): true, then exited after 83ms exitCode=129 signal=0, where 129 is the CLI's own handled-hangup exit code.
• Regression test, wait removed: 1 failed | 6 passed (7) — cleanup() returned before the interactive CLI child exited: expected 0 to be greater than or equal to 750. Regression test, kill removed: 1 failed | 6 passed (7) — Matcher did not succeed in time. Both restored: 7 passed (7).

Environment (optional)

Linux (Node 22) inside a container, QWEN_SANDBOX=false, QWEN_E2E_RENDERER=ink, against the bundled dist/cli.js, with the runner-environment variable unset so unhandled errors stay fatal exactly as they are on the OpenTUI leg. The opentui leg was not run: bun is unavailable there and the renderer matrix throws without it. The defect and the fix are renderer-independent — the signal handler is installed for any interactive session, gated only on interactivity — but the leg that reddens is the one that could not be executed here.

Risk & Scope

• Main risk or tradeoff: teardown now blocks until each leaked session exits, so a child that never dies would add the full bound to that test's teardown, and hook time counts against the test timeout. The bound is deliberately above the CLI's own five-second shutdown ceiling, the measured reality is tens of milliseconds, and a child that ignores the signal entirely is not one this suite produces. Before the change such a child leaked silently and could redden the whole run without naming a test; now the worst case is bounded and visible. Sessions a test already closed cost nothing, because their exit has been observed before teardown runs.
• Not validated / out of scope: the OpenTUI leg under bun, and the sandbox:none shards, which need the self-hosted pool. Also deliberately untouched is whether github-hosted Linux should keep treating unhandled errors as fatal — that leg is the only Linux lane with the exemption off, so any other unhandled error is fatal there alone, and whether that is the right signal policy is a maintainer call, as fix(test): end interactive PTY sessions a test never closed #10971 also judged. This change removes one proven source; it is not a guarantee the leg stops reddening. Separately noted and not implemented: one interactive file carries its own copy of the launcher and never applies the renderer overlay, so on the OpenTUI leg it drives the CLI under node with the default renderer rather than under bun with the pinned one, sitting outside the guarantee the renderer matrix exists to enforce. It is not implicated here — it closes its own session and waits — and moving it onto bun would change what that file exercises. The second job named in the issue, a sandbox:none shard, was the documented transient shared-host pressure class whose one-shot retry was starved by a per-leg build that main has since removed; the same shard failing afterwards is tracked by Main CI failed: E2E Tests on d4e3e4fc8747 #10994.
• Breaking changes / migration notes: none. The change is confined to the test harness and adds no production behaviour.

中文说明

这个 PR 做了什么

让交互式测试框架等待它结束的每一个终端会话，而不是发个信号就走。rig 本来就会记住它生成的每一个伪终端子进程，并终止那些测试没有关闭的；现在它还会阻塞等待这些子进程真正退出，上界设在高于 CLI 自身关闭天花板的位置，因此一个拒绝死掉的子进程不会把 teardown 挂死。该上界使用的 timer 不会留下任何撑住 worker 事件循环的东西。

覆盖这一点的回归测试是就地加强的，而不是另写一个。它替代 CLI 的替身现在行为与真实 CLI 一致 —— 捕获终止信号，并且只在一段延迟之后退出 —— 并且在框架被允许向它发信号之前，先宣告自己已经启动完毕。测试断言的是"等待"本身，因此移除守卫的任意一半都会让它变红：发信号，或等待信号生效。

为什么需要它

E2E Interactive - OpenTUI renderer (bun) 这个 leg 一直在让 main 变红，却不指出任何一个失败的测试。最近九次运行里有六次如此，而这六次中有一次正是为修复它而合入 #10971 的那个 commit —— 所以那次修复收窄了这一类问题，却没有关闭它。失败步骤的耗时与健康步骤相当，说明套件是跑完了、之后进程才死掉；而日志里完全没有失败行，这正是检测器按 commit 而不是按测试来记录的原因。一个所有测试都通过却仍以非零码退出的 run，是 unhandled error。

#10971 正确识别了机制：测试没有关闭的会话会一直活到 run 结束，并且因为同样的环境设置开启了冗长转发，它仍在把每一个终端字节转发进 worker 的标准输出；一旦 vitest 拆除 worker，该管道的读取端就消失了 —— 下一次写入产生 EPIPE，Node 将其升级为未捕获异常。它漏掉的是：向会话发信号并不等于结束会话。CLI 对任何交互式会话都会捕获 hangup 信号，无论使用哪个渲染器，并且只有在一条异步关闭链排空之后才退出：chat-recording flush、MCP 子进程停止、telemetry shutdown、session-usage 持久化，全部由一个五秒的墙钟上界约束。因此框架从 teardown 返回时子进程仍然活着、仍在写入，#10971 想要关闭的那个窗口依然开着。

两部分都是实测得到的，不是假设。针对真实 bundle，子进程在 kill 调用返回的那一刻仍然活着，并在 83 毫秒后以退出码 129 结束 —— 那是 CLI 自己处理 hangup 时使用的退出码。而在父提交上的一次整 leg 运行中，监视进程表抓到了一个 CLI 子进程在其 vitest worker 退出的那一刻被 reparent 给 init，而那恰恰是 EPIPE 致命而非无害的瞬间；它的存活时长与它同胞进程的时长，与那个"启动会话却从不关闭"的文件里两个测试的耗时对得上。改动之后，同样的测量在两次整 leg 运行中都没有发现任何孤儿进程，且通过的测试集合完全一致。

早先那个 witness 为什么没抓到，值得记录下来，因为这正是一次修复已经"绿着"上线的原因。它的替身没有信号 handler，因此会以默认动作立刻死掉；而且它通过一个十秒超时的 poll 来断言 —— 这个 poll 完全乐意接受子进程比 teardown 多活最多十秒。真正要紧的性质"到 teardown 返回时已经消失"，从来没有任何东西把它固定下来。

Reviewer 测试计划

如何验证

承重的主张是：teardown 返回时没有任何交互式会话仍然活着，而 rig 自己测试文件里的回归测试就是它的全部。在本分支上它大约一秒通过。切到父提交，只应用测试改动，它会失败并报告 teardown 在子进程退出之前就返回了 —— 实测 0 毫秒，对照 750 毫秒的下限。它不需要模型凭据、不需要 bun、不需要网络，因为替身是一段短脚本而不是 CLI。

要确认守卫的两半都有 witness，逐个删除并重跑该文件。移除"等待"会在耗时下限上失败。移除"发信号"会在存活 poll 上失败，且是在上界与 poll 都到期之后。恢复任意一个都会回到绿色。

更大的套件应当保持不变：运行 interactive leg 并与 main 对比，期望收集到同样的十个文件、通过同样的十八个测试、跳过同样的两个，且没有新增跳过。这一点对那些本应自行结束的会话最为重要 —— Ctrl+C 退出用例，以及 mid-turn 的 quit 用例 —— 因为 teardown 现在会等待这些测试已经终止过的子进程，而对它们来说等待会立刻解除，因为退出早已被观察到。

也值得在该 leg 运行期间观察进程表，这正是缺陷被抓到的方式。在 main 上，一个 CLI 子进程比它的 worker 活得更久并被 reparent 给 init；在本分支上一个都没有。

代价很小且可测：等待就是每个会话真实的关闭耗时，实测 35–42 毫秒，而唯一泄漏会话的那个文件增长了 38 毫秒。整 leg 的墙钟时间由一个真实模型的压缩文件主导，它的单个测试在不同 run 之间会在 71 秒到 107 秒之间摆动，所以判断本改动是否拖慢了任何东西时，请对比各文件耗时而不是总时长。

OpenTUI leg 本身是最终检查，需要 bun；在准备这一改动的环境里无法运行。由于失败是间歇性的 —— 该 leg 在本 issue 所针对 commit 的下一个 commit 上、在这些工作开始之前就通过了 —— 单独一次绿色运行说明不了太多。有意义的信号是："退出码 1、无失败测试"这个形态是否在若干次合并之后不再复现。

证据（前后对比）

非 UI 改动，因此没有截图。测得的前后对比是整 interactive leg 运行期间的进程表：

• 修复前（父提交）：一个 CLI 子进程被 reparent 给 init —— ppid 2130 → 1 —— 出现在整个 run 的最后一次采样，也就是 worker 拆除时。整 leg 结果：9 passed | 1 skipped (10) 个文件、18 passed | 2 skipped (20) 个测试、exit 0。
• 修复后（本分支，两次独立的整 leg 运行）：0 个孤儿，run 结束十五秒后 0 个残留。整 leg 结果完全相同：9 passed | 1 skipped (10) 个文件、18 passed | 2 skipped (20) 个测试、exit 0。
• 针对真实 bundle 的直接测量：alive immediately after kill(): true，随后 exited after 83ms exitCode=129 signal=0，其中 129 是 CLI 自己处理 hangup 的退出码。
• 回归测试，移除等待：1 failed | 6 passed (7) —— cleanup() returned before the interactive CLI child exited: expected 0 to be greater than or equal to 750。回归测试，移除 kill：1 failed | 6 passed (7) —— Matcher did not succeed in time。两者都恢复后：7 passed (7)。

环境（可选）

容器内的 Linux（Node 22），QWEN_SANDBOX=false，QWEN_E2E_RENDERER=ink，针对打包后的 dist/cli.js 运行，并 unset runner-environment 变量，使 unhandled error 保持致命，与 OpenTUI leg 完全一致。opentui leg 未运行：该环境中没有 bun，渲染器矩阵在缺少它时会抛错。缺陷与修复都与渲染器无关 —— 信号 handler 对任何交互式会话都会安装，只以"是否交互式"为条件 —— 但变红的恰恰是这里无法执行的那个 leg。

风险与范围

• 主要风险或取舍：teardown 现在会阻塞到每个泄漏的会话退出为止，因此一个永不死掉的子进程会给该测试的 teardown 增加完整的上界时长，而 hook 时间是计入测试超时的。上界刻意设在高于 CLI 自身五秒关闭天花板的位置，实测情况是数十毫秒，而完全忽略信号的子进程并不是本套件会产生的。改动之前，这样的子进程会静默泄漏，并可能在不指出任何测试的情况下让整个 run 变红；现在最坏情况是有界且可见的。测试已经自行关闭的会话不产生任何代价，因为它们的退出在 teardown 运行之前就已被观察到。
• 未验证 / 范围之外：bun 下的 OpenTUI leg，以及需要 self-hosted 池的 sandbox:none 各 shard。同样刻意未触碰的是：github-hosted Linux 是否应继续把 unhandled error 判为致命 —— 该 leg 是唯一关闭豁免的 Linux 通道，因此任何其它 unhandled error 都只在它这里是致命的，而这是否是正确的信号策略属于维护者的决定，fix(test): end interactive PTY sessions a test never closed #10971 也做了同样判断。本改动移除了一个被证明的来源；它不保证该 leg 不再变红。另外记录但未实现：有一个交互式文件自带一份启动器副本，且从不套用渲染器 overlay，因此在 OpenTUI leg 上它是用 node 加默认渲染器驱动 CLI，而不是用 bun 加被钉住的渲染器，落在渲染器矩阵本要保证的范围之外。它与本次问题无关 —— 它自己关闭会话并等待 —— 而把它搬到 bun 上会改变该文件实际验证的内容。issue 中指出的第二个 job，一个 sandbox:none shard，属于已记录在案的共享宿主压力瞬时类别，它的一次性重试被 per-leg 构建耗尽了预算，而 main 此后已移除该构建；同一 shard 在此之后仍然失败，由 Main CI failed: E2E Tests on d4e3e4fc8747 #10994 跟踪。
• 破坏性变更 / 迁移说明：无。改动仅限于测试框架，不新增任何生产行为。

E2E report — issue #10990 (Main CI failed: E2E Tests on b7815a7)

What the issue names, and what each half turned out to be

Run 33829764813 at b7815a7e1a reddened two jobs. Neither printed a FAIL line, which is why the detector filed per commit instead of naming a test — it matches ^FAIL\s+ after stripping ANSI and the Actions timestamp, and found nothing.

E2E Interactive - OpenTUI renderer (bun) — this is a recurring failure, not a one-off. That leg failed in runs 33797332289, 33806428062, 33813966397, 33820259657 (the commit carrying the #10969 repair itself), 33829764813 and 33830499451, interleaved with passes at 33795521868, 33811905769 and 33831058473. So #10971 narrowed the class but did not close it. The failing step ran 196s against a healthy 86–192s, i.e. the suite ran to completion and the process then died. This half is what the change below repairs.

E2E Test (Linux) - sandbox:none - shard 2/3 — the job's own annotation states the outcome: sandbox:none shard failed on ecs-qwen-hk4-28 after 2334s of the 3600s job budget — not enough left for a retry. That is the transient shared-host pressure class the workflow already documents and already has a one-shot retry for; the retry never ran because the budget gate needs ≤2100s elapsed, and this tree still built on the leg (step 11 Build project alone took 12m40s, so setup consumed 16m29s of the 60-minute job). main has since taken #10894, which builds once on a hosted runner and unpacks on every leg: at d4e3e4fc87 the same job's setup fell to 2m36s, attempt 1 failed at 1444s, and the retry did fire (retrying once (transient shared-host pressure class)). Both attempts still failed there, and that run is tracked separately by #10994, which already carries autofix/in-progress. No code change in this PR touches that half, and .github/ is deliberately left alone.

Root cause of the interactive-leg failure

#10971 made TestRig.cleanup() kill every session runInteractive() spawned. It signals, but it does not wait — and signalling is not the same as ending.

The CLI installs process.on('SIGHUP', …) for any interactive session regardless of renderer, and node-pty's kill() defaults to SIGHUP. That handler runs an exit-cleanup chain — chat-recording flush, config.shutdown() (which stops MCP subprocesses), telemetry shutdown, session-usage persisting — bounded by a 5s wall clock, and only then calls process.exit(129). So cleanup() returned while the child was still alive and still forwarding PTY bytes into the worker's process.stdout under the VERBOSE/KEEP_OUTPUT this leg sets. Vitest then tore the worker down around a live child, which is exactly the EPIPE-on-a-destroyed-stdout-pipe path #10969 described.

Measured against the real bundle rather than inferred:

PROBE alive immediately after kill(): true
PROBE exited after 83ms exitCode=129 signal=0

exitCode=129 is the CLI's own getSignalExitCode('SIGHUP'), which confirms the trapped-graceful path and not the default action.

A full interactive-leg run on the parent commit, watching the process table, caught the consequence directly — a CLI child whose vitest worker exited underneath it and was reparented to init:

[t=83]    3678    2130      82 node   node …/dist/cli.js --no-chat-recording --yolo
[t=84]    3678       1      84 node   node …/dist/cli.js --no-chat-recording --yolo

Its lifetime (84s) and its sibling's (76s) match that file's two test durations in the same run (84.5s and 77.8s), so these are the sessions context-compress-interactive.test.ts starts and never closes. The orphan appeared at the last sample of the run — the exact moment the worker tears down, which is when an EPIPE is fatal rather than harmless.

Why #10971's witness did not catch this: its stand-in was setInterval(() => {}, 1000), which has no SIGHUP handler and so dies on the default action instantly, and it asserted with expect.poll(…, { timeout: 10_000 }) — a poll that tolerates the child surviving cleanup() for up to ten seconds. The property that matters, "dead by the time cleanup() returns", was never pinned.

The change

cleanup() now waits for each session it signalled to actually exit, bounded above the CLI's own 5s drain ceiling so a pathological child cannot hang teardown. The wait resolves on node-pty's exit event; the bound's timer is cleared and unrefed so a won race leaves no handle holding the worker's event loop open — a lingering timer here would recreate the very "worker cannot exit" condition being fixed.

The witness was strengthened in place rather than added alongside, so it fails on both halves of the guard: the stand-in now traps SIGHUP and exits 750ms later like the real CLI, and reports itself booted first. That second part was necessary, not decorative — signalling a child before node has installed its handler ends it on the default action in ~3ms, which measured nothing and let the first version of this test fail against a correct fix.

Verification

Every command below was actually run in this checkout (161c784514), on Linux/Node 22.23.2 inside the Qwen sandbox container.

Required checks:

• npm run build — passed (BUILD_EXIT=0)
• npm run typecheck — passed (exit 0, including typecheck:integration)
• npm run lint — passed (exit 0; eslint . --ext .ts,.tsx && eslint integration-tests)
• npx prettier --check integration-tests/test-helper.ts integration-tests/test-helper.test.ts — passed ("All matched files use Prettier code style!")
• Focused vitest, vitest run --root ./integration-tests test-helper.test --retry=0 — 7 passed (7), exit 0
• Full interactive leg in the CI command shape (QWEN_E2E_RENDERER=ink QWEN_SANDBOX=false KEEP_OUTPUT=true VERBOSE=true vitest run --root ./integration-tests interactive --exclude '**/interactive/cron-interactive.test.ts' --exclude '**/channel-plugin.test.ts', RUNNER_ENVIRONMENT unset so dangerouslyIgnoreUnhandledErrors is false exactly as on the OpenTUI leg) — run three times, all exit 0 with an identical result set of 9 passed | 1 skipped (10) files and 18 passed | 2 skipped (20) tests: once on the parent commit as the baseline, once after the fix, and once after the fix against the freshly rebuilt bundle
• vitest run --root ./integration-tests context-compress-interactive --retry=0 — 2 passed | 1 skipped (3), exit 0

Mutation probes (each guard has its own witness; the file was restored from a byte copy after each, and the restore was re-run to green):

• Removed await settleWithin(exited, INTERACTIVE_EXIT_GRACE_MS) from cleanup() → witness FAILED: cleanup() returned before the interactive CLI child exited: expected 0 to be greater than or equal to 750. Restored → 7 passed.
• Removed the ptyProcess.kill() block from cleanup() → witness FAILED: Matcher did not succeed in time after 20211ms (the 10s grace plus the 10s survival poll). Restored → 7 passed.

Orphan and survivor measurement, whole-leg runs with a 2s process-table sampler:

• Parent commit: 1 CLI child reparented to init (pid 3678, ppid 2130 → 1) at worker teardown.
• After the fix: 0 orphans and 0 survivors 15s after the run, on two separate whole-leg runs.

Cost of the wait, measured by instrumenting cleanup() (instrumentation removed afterwards, not committed):

PROBE cleanup waited 37ms for pid 7596
PROBE cleanup waited 42ms for pid 7598
PROBE cleanup waited 35ms for pid 7735

Independently corroborated by per-file timings: hooks-command.test.ts went 2509ms → 2547ms (+38ms, the measured wait). The whole-leg duration moved 166s → 190s → 308s across the three runs, and that swing is entirely context-compress-interactive.test.ts (162.3s → 187.1s → 303.9s) while every other file stayed inside ±250ms. That file drives live /compress model calls; its individual tests measured 71s, 90s, 107s and 106s across runs, so the variance is model latency, not teardown.

Not run, and why:

• The OpenTUI leg itself. bun is not installed in this environment and resolveE2eCliCommand('opentui') throws without it. Everything above ran under QWEN_E2E_RENDERER=ink. The defect and the fix are renderer-independent — the SIGHUP handler is installed for any interactive session, gated only on config.isInteractive() — but the leg that reddens is the one that could not be executed here.
• E2E Test (Linux) - sandbox:none shards. They need the self-hosted ECS pool; see the Main CI failed: E2E Tests on d4e3e4fc8747 #10994 note above.

Honest limits of this repair

This removes one proven source of unhandled errors on that leg, measured end to end. It is not a guarantee the leg stops reddening, for three reasons worth stating plainly:

1. The leg passed at d4e3e4fc87 before this change, so a green OpenTUI run afterwards is not evidence for the fix. The meaningful signal is whether the "exit code 1, no failing test" shape stops recurring across several merges.
2. That leg is the only Linux lane with dangerouslyIgnoreUnhandledErrors off (the shards moved to the self-hosted pool in ci: run the Linux E2E shards on the persistent pool #10085 and macOS is exempt by platform), so any other unhandled error is fatal there alone — including the onTaskUpdate RPC 60s-stall class the integration vitest config already documents. Whether hosted Linux should keep treating unhandled errors as fatal is a maintainer call about signal, and fix(test): end interactive PTY sessions a test never closed #10971 deliberately left it alone; this PR does too.
3. One intermittent assertion failure in context-compress-interactive.test.ts was observed in a single instrumented run and did not reproduce when that file was run alone (2 passed | 1 skipped). It is a live-model test whose per-test duration swings by tens of seconds, and the change here touches only teardown timing (+38ms measured), so there is no causal path from it to a mid-test assertion. Recorded rather than quietly dropped.

One observation, deliberately not implemented

external-context-mem0-write.test.ts carries its own copy of the interactive launcher, which spawns process.execPath with env: process.env and never applies the renderer overlay. On the OpenTUI leg that file therefore drives the CLI under node with the ink default, not bun with QWEN_TUI_RENDERER=opentui plus QWEN_TUI_RENDERER_STRICT — so it sits outside the guarantee the renderer matrix exists to enforce. It is not implicated in this failure (it kills its own session in a finally and awaits the exit, so it never leaked), and moving it onto bun would change what that file exercises and could introduce failures unrelated to this issue. Flagged for a maintainer rather than folded into a CI-repair diff.

E2E 报告 —— issue #10990（Main CI failed: E2E Tests on b7815a7）

Issue 指出的两个 job，各自的真实性质

Run 33829764813（commit b7815a7e1a）有两个 job 变红。两者都没有打印任何 FAIL 行，这正是检测器按 commit 而不是按测试来记录的原因 —— 它在剥离 ANSI 与 Actions 时间戳之后匹配 ^FAIL\s+，什么都没匹配到。

E2E Interactive - OpenTUI renderer (bun) —— 这是反复出现的失败，不是偶发。该 leg 在 run 33797332289、33806428062、33813966397、33820259657（即携带 #10969 修复的那个 commit）、33829764813 和 33830499451 中都失败了，中间夹着 33795521868、33811905769 和 33831058473 的通过。所以 #10971 收窄了这一类问题，但没有关闭它。失败步骤耗时 196 秒，而健康区间是 86–192 秒，也就是说套件跑完了，然后进程才死掉。下面这个改动修的就是这一半。

E2E Test (Linux) - sandbox:none - shard 2/3 —— 该 job 自己的 annotation 已经说明了结果：sandbox:none shard failed on ecs-qwen-hk4-28 after 2334s of the 3600s job budget — not enough left for a retry。这正是 workflow 已经记录在案、并且已经配了一次重试的"共享宿主压力"瞬时类别；重试没有执行，是因为预算闸门要求 elapsed ≤2100s，而这棵树仍然在 leg 上自行构建（仅 step 11 Build project 就花了 12 分 40 秒，setup 一共吃掉了 60 分钟 job 预算里的 16 分 29 秒）。main 随后合入了 #10894，改为在托管 runner 上构建一次、各 leg 解包使用：在 d4e3e4fc87 上同一个 job 的 setup 降到 2 分 36 秒，第一次尝试在 1444 秒失败，重试确实触发了（retrying once (transient shared-host pressure class)）。但两次尝试仍然都失败，那一次 run 由 #10994 单独跟踪，且该 issue 已带 autofix/in-progress。本 PR 没有任何代码改动涉及这一半，并且刻意没有碰 .github/。

交互式 leg 失败的根因

#10971 让 TestRig.cleanup() 去 kill runInteractive() 生成的每一个会话。但它只发信号，不等待 —— 而发信号并不等于结束。

CLI 对任何交互式会话都会注册 process.on('SIGHUP', …)，与渲染器无关，而 node-pty 的 kill() 默认发送 SIGHUP。该 handler 会执行一条退出清理链 —— chat-recording flush、config.shutdown()（它会停掉 MCP 子进程）、telemetry shutdown、session-usage 持久化 —— 由一个 5 秒的墙钟上界约束，之后才调用 process.exit(129)。因此 cleanup() 返回时子进程仍然活着，并且在本 leg 设置的 VERBOSE/KEEP_OUTPUT 下继续把 PTY 字节转发进 worker 的 process.stdout。随后 vitest 在一个活着的子进程外面拆掉了 worker，而这恰恰就是 #10969 所描述的"向已销毁的 stdout 管道写入导致 EPIPE"路径。

针对真实 bundle 实测（而非推断）：

PROBE alive immediately after kill(): true
PROBE exited after 83ms exitCode=129 signal=0

exitCode=129 正是 CLI 自己的 getSignalExitCode('SIGHUP')，证明走的是被捕获的优雅退出路径，而不是默认动作。

在父提交上跑一次完整的 interactive leg，同时监视进程表，直接抓到了后果 —— 一个 CLI 子进程，它的 vitest worker 在其身下退出，于是它被 reparent 给 init：

[t=83]    3678    2130      82 node   node …/dist/cli.js --no-chat-recording --yolo
[t=84]    3678       1      84 node   node …/dist/cli.js --no-chat-recording --yolo

它的存活时长（84 秒）与它的同胞进程（76 秒）正好对应该文件在同一次运行中的两个测试耗时（84.5 秒和 77.8 秒），所以这些正是 context-compress-interactive.test.ts 启动却从不关闭的会话。孤儿进程出现在整个 run 的最后一次采样 —— 也正是 worker 拆除的那一刻，此时 EPIPE 是致命的，而不是无害的。

#10971 的 witness 为什么没抓到：它的替身是 setInterval(() => {}, 1000)，没有 SIGHUP handler，因此会以默认动作立刻死掉；而且它用 expect.poll(…, { timeout: 10_000 }) 断言 —— 这个 poll 容忍子进程在 cleanup() 之后继续存活最多十秒。真正要紧的性质"到 cleanup() 返回时已经死掉"从未被固定下来。

改动内容

cleanup() 现在会等待它发过信号的每个会话真正退出，上界设在高于 CLI 自身 5 秒 drain 天花板的位置，因此病态子进程不会把 teardown 挂死。等待以 node-pty 的 exit 事件为解除条件；上界用的 timer 会被 clear 且 unref，所以竞争获胜后不会留下任何把 worker 事件循环撑住的 handle —— 这里若残留一个 timer，就会重新造出我们正在修的那个"worker 无法退出"状态。

witness 是就地加强的，而不是另加一个，因此它对这道守卫的两半都会失败：替身现在会像真实 CLI 一样捕获 SIGHUP 并在 750 毫秒后退出，并且先报告自己已启动。第二点不是装饰而是必需 —— 在 node 装好 handler 之前发信号，会在约 3 毫秒内以默认动作结束子进程，什么都测不到，也正是这一点让本测试的第一个版本在一个正确的修复面前失败了。

验证

下面每条命令都在本 checkout（161c784514）中真实执行过，环境为 Qwen sandbox 容器内的 Linux / Node 22.23.2。

必需检查：

• npm run build —— 通过（BUILD_EXIT=0）
• npm run typecheck —— 通过（exit 0，含 typecheck:integration）
• npm run lint —— 通过（exit 0；eslint . --ext .ts,.tsx && eslint integration-tests）
• npx prettier --check integration-tests/test-helper.ts integration-tests/test-helper.test.ts —— 通过（"All matched files use Prettier code style!"）
• 定向 vitest，vitest run --root ./integration-tests test-helper.test --retry=0 —— 7 passed (7)，exit 0
• 以 CI 命令形态跑完整 interactive leg（QWEN_E2E_RENDERER=ink QWEN_SANDBOX=false KEEP_OUTPUT=true VERBOSE=true vitest run --root ./integration-tests interactive --exclude '**/interactive/cron-interactive.test.ts' --exclude '**/channel-plugin.test.ts'，并 unset RUNNER_ENVIRONMENT，使 dangerouslyIgnoreUnhandledErrors 为 false，与 OpenTUI leg 完全一致）—— 共跑三次，全部 exit 0 且结果集完全相同：9 passed | 1 skipped (10) 个文件、18 passed | 2 skipped (20) 个测试；分别在父提交（基线）、修复后、以及修复后针对重新构建的 bundle 各跑一次
• vitest run --root ./integration-tests context-compress-interactive --retry=0 —— 2 passed | 1 skipped (3)，exit 0

变异探针（每道守卫都有自己的 witness；每次之后都用字节副本还原文件，并重跑到绿色）：

• 从 cleanup() 中移除 await settleWithin(exited, INTERACTIVE_EXIT_GRACE_MS) → witness 失败：cleanup() returned before the interactive CLI child exited: expected 0 to be greater than or equal to 750。还原后 → 7 passed。
• 从 cleanup() 中移除 ptyProcess.kill() 代码块 → witness 失败：20211 毫秒后 Matcher did not succeed in time（10 秒 grace 加 10 秒存活 poll）。还原后 → 7 passed。

孤儿与残留进程测量，整 leg 运行并以 2 秒间隔采样进程表：

• 父提交：1 个 CLI 子进程在 worker 拆除时被 reparent 给 init（pid 3678，ppid 2130 → 1）。
• 修复后：两次独立的整 leg 运行中均为 0 个孤儿、run 结束 15 秒后 0 个残留进程。

等待的代价，通过给 cleanup() 加插桩测得（插桩随后已移除，未提交）：

PROBE cleanup waited 37ms for pid 7596
PROBE cleanup waited 42ms for pid 7598
PROBE cleanup waited 35ms for pid 7735

并由各文件耗时独立佐证：hooks-command.test.ts 从 2509ms 变为 2547ms（+38ms，与实测等待一致）。整 leg 时长在三次运行中为 166s → 190s → 308s，而这个摆动完全来自 context-compress-interactive.test.ts（162.3s → 187.1s → 303.9s），其余每个文件都在 ±250ms 之内。该文件驱动真实的 /compress 模型调用；其单个测试在各次运行中测得 71s、90s、107s 和 106s，所以这个方差是模型延迟，不是 teardown。

未运行，及原因：

• OpenTUI leg 本身。 本环境没有安装 bun，而 resolveE2eCliCommand('opentui') 在缺少它时会抛错。以上全部在 QWEN_E2E_RENDERER=ink 下运行。缺陷与修复都与渲染器无关 —— SIGHUP handler 对任何交互式会话都会安装，只以 config.isInteractive() 为条件 —— 但变红的恰恰是这里无法执行的那个 leg。
• E2E Test (Linux) - sandbox:none 各 shard。 它们需要 self-hosted ECS 池；见上文 Main CI failed: E2E Tests on d4e3e4fc8747 #10994 的说明。

对本次修复的诚实边界

这移除了该 leg 上一个被端到端实测证明的 unhandled error 来源。它并不保证该 leg 不再变红，有三点需要明白写出：

1. 该 leg 在 d4e3e4fc87 上、在本改动之前就通过了，所以之后一次绿色的 OpenTUI run 并不能作为本修复的证据。有意义的信号是："exit code 1、无失败测试"这个形态是否在若干次合并之后不再复现。
2. 该 leg 是唯一关闭 dangerouslyIgnoreUnhandledErrors 的 Linux 通道（各 shard 在 ci: run the Linux E2E shards on the persistent pool #10085 中迁到了 self-hosted 池，macOS 按平台豁免），因此任何其他 unhandled error 都只在它这里是致命的 —— 包括 integration vitest 配置里已经记录在案的 onTaskUpdate RPC 60 秒停滞类别。托管 Linux 是否应继续把 unhandled error 判为致命，是维护者关于信号取舍的决定，fix(test): end interactive PTY sessions a test never closed #10971 刻意没有碰它；本 PR 同样没有碰。
3. 在一次带插桩的运行中观察到 context-compress-interactive.test.ts 出现过一次间歇性断言失败，单独运行该文件时未复现（2 passed | 1 skipped）。它是一个真实模型测试，单个测试耗时会有数十秒的摆动，而本改动只影响 teardown 时序（实测 +38ms），因此从它到测试中途断言之间不存在因果路径。此处如实记录，而不是悄悄略过。

一条观察，刻意未实现

external-context-mem0-write.test.ts 自带一份交互式启动器的副本，它用 env: process.env 启动 process.execPath，并且从不套用渲染器 overlay。因此在 OpenTUI leg 上，该文件实际是用 node 加 ink 默认渲染器驱动 CLI，而不是 bun 加 QWEN_TUI_RENDERER=opentui 与 QWEN_TUI_RENDERER_STRICT —— 也就是说它落在渲染器矩阵本要保证的范围之外。它与本次失败无关（它在 finally 里 kill 自己的会话并等待退出，因此从未泄漏），而把它搬到 bun 上会改变该文件实际验证的内容，并可能引入与本 issue 无关的失败。因此提请维护者注意，而不是塞进一个 CI 修复的 diff 里。

Template looks good ✓

Problem: observed, not theoretical. #10990 is a machine-filed main-CI failure — E2E Interactive - OpenTUI renderer (bun) exits non-zero without naming a single failing test — and the description carries real measurements behind the diagnosis rather than a plausible story. Two of them matter: the child is still alive the instant kill() returns and exits 83ms later with code 129 (the CLI's own handled-hangup code), and a whole-leg run on the parent commit caught a CLI child being reparented to init (ppid 2130 → 1) at worker teardown. That second observation is the load-bearing one, because it pins the exact instant an EPIPE stops being harmless. I confirmed the mechanism in the harness itself — runInteractive forwards every PTY byte to process.stdout whenever KEEP_OUTPUT or VERBOSE is set, which is what CI runs with, so a child that outlives its worker really is writing into a pipe with no reader.

Direction: aligned. This is test-infrastructure health, not a product surface — no production behaviour and no public contract change. The CHANGELOG signal doesn't apply to an internal harness fix. I want to call out the honesty in the scope statement: it claims to remove one proven source of the red leg and explicitly declines to claim the leg stops reddening, and it leaves "should github-hosted Linux keep treating unhandled errors as fatal" to a maintainer instead of quietly flipping that policy while it was in the neighbourhood.

Size: not applicable — no core paths are touched. Two files under integration-tests/, 58 additions / 8 deletions, and 29 of those added lines are in the test file itself.

Approach: the scope feels right, and strengthening the existing regression test in place rather than adding a parallel one is the correct call. The description also explains why the earlier witness missed this — the stand-in had no signal handler so it died on the default action, and the assertion polled with a ten-second timeout that was perfectly happy to let the child outlive teardown by up to ten seconds. Recording that is what stops the same fix shipping green a second time, and it's the part of this PR I'd most want future contributors to read.

Risk: no elevated risk signals — neither file matches the revert-correlated path list.

One thing I'm carrying into code review: the grace bound is 10s and cleanup() is called from afterEach across the interactive suite, so I want to check which budget actually governs that hook and whether the bound fits inside it.

问题： 是已观测到的，不是理论性的。#10990 是自动创建的 main CI 失败 issue —— E2E Interactive - OpenTUI renderer (bun) 以非零码退出，却没有指出任何一个失败的测试 —— 而 PR 描述给出的是实测数据，而不是一个"听起来合理"的故事。其中两点是关键：子进程在 kill() 返回的那一刻仍然活着，并在 83 毫秒后以退出码 129 结束（这是 CLI 自己处理 hangup 时用的码）；在父提交上的一次整 leg 运行中，抓到一个 CLI 子进程在 worker 拆除时被 reparent 给 init（ppid 2130 → 1）。第二个观测是承重的，因为它精确定位了 EPIPE 从"无害"变成"致命"的那一刻。我在 harness 代码里确认了这个机制 —— runInteractive 在设置了 KEEP_OUTPUT 或 VERBOSE 时会把每一个 PTY 字节转发到 process.stdout，而 CI 正是这样跑的，所以一个比 worker 活得更久的子进程，确实是在往一个没有读取端的管道里写。

方向： 对齐。这是测试基础设施的健康度，不是产品面 —— 没有生产行为改动，也没有公共契约变化。CHANGELOG 信号对内部 harness 修复不适用。这里要特别指出范围陈述的诚实：它只声称移除了一个被证明的红 leg 来源，明确不声称该 leg 从此不再变红；并且把"github-hosted Linux 是否应继续把 unhandled error 判为致命"留给维护者决定，而没有顺手在自己路过时改掉这个策略。

规模： 不适用 —— 没有触及核心路径。integration-tests/ 下两个文件，58 增 8 删，其中 29 行新增在测试文件里。

方案： 范围合理，而且就地加强已有回归测试、而不是另写一个平行测试，是正确的选择。描述还解释了为什么早先那个 witness 没抓到 —— 替身没有信号 handler，所以以默认动作立刻死掉；而断言用的是一个十秒超时的 poll，这个 poll 完全乐意接受子进程比 teardown 多活最多十秒。把这一点记录下来，正是防止同一个修复第二次"绿着"上线的关键，也是这个 PR 里我最希望后来的贡献者去读的部分。

风险： 无升级风险信号 —— 两个文件都不匹配与 revert 相关的路径列表。

有一点我带进代码审查：grace 上界是 10 秒，而 cleanup() 在整个 interactive 套件里都是从 afterEach 调用的，所以我要确认到底是哪个预算在管这个 hook，以及这个上界是否装得进去。

Code review

I wrote down what I'd do before opening the diff: track an exit promise per PTY session captured at spawn time, await it in cleanup() after signalling, bound the wait above the CLI's own 5s shutdown ceiling, make sure the bound's timer can't hold the worker's event loop open, and memoise the promise so a session a test already closed resolves immediately. The PR does all five. It also independently landed the subtlety I'd have had to be talked into — the stand-in in the test now announces STAND_IN_READY before the harness is allowed to signal it, because a signal delivered before the handler exists kills the child on the default action and measures nothing. That's precisely the hole that let #10971 ship green, and closing it in the witness is what makes this fix hard to silently undo.

So: no correctness blockers, no security concerns, no regressions I can find. The mechanism is sound and I checked the parts that could quietly not work.

What I verified

• Two onExit listeners on one pty. The diff registers a second onExit alongside the existing one that resolves promise, so if node-pty only honoured one, either the new wait or the existing exit-code reporting would silently break. It's fine — packages/core/src/services/shellExecutionService.ts registers two concurrently (lines 1860 and 2150), and the disposable-per-registration signature is the array-listener pattern. CI corroborates it empirically, which is better than my reading: had the second registration clobbered the first, exited would never resolve, settleWithin would burn the full 10s grace, and test-helper.test.ts could not have finished in 965ms. It did, while asserting cleanupTookMs >= 750. The wait is resolving on the real exit event, not on the timeout.
• No missed-exit race. onExit is registered synchronously in the same tick as pty.spawn, so a child cannot exit-and-be-reaped before the listener exists.
• Already-closed sessions cost nothing. The promise is captured at spawn and stored in the tracked entry, so a session a test closed itself is already resolved by the time cleanup() splices the list. This is what makes the PR's claim about the Ctrl+C and mid-turn quit cases hold, and it's the reason the change can't slow down the tests that were already well-behaved.
• settleWithin cannot newly fail a teardown. Both race outcomes resolve rather than reject, and clearTimeout runs on either path. Correct choice for a cleanup path — a bound that threw would turn a leaked child into a failed test.
• Nothing left holding the loop. timer.unref() plus clearTimeout on both outcomes. The comment slightly oversells why unref is needed (node-pty's own handles keep the loop alive while the child lives, so the timer fires regardless), but it's harmless and the right instinct for code that runs during worker teardown.

One suggestion — the grace bound collides exactly with the hook budget

INTERACTIVE_EXIT_GRACE_MS is 10_000. cleanup() is called from afterEach across the interactive suite (hooks-command, context-compress-interactive, mid-turn-submit-interactive, external-context-*, …), and integration-tests/vitest.config.ts sets testTimeout to 5 minutes but never sets hookTimeout — it's the one vitest config in the repo that doesn't. Every other package pins it deliberately (packages/cli, packages/core, packages/web-shell, packages/acp-bridge, packages/node-repl, packages/qwen-live, packages/sdk-typescript, which sets it to 10000). So the hook that governs afterEach runs on Vitest's documented 10s default — the same number as the grace bound, with zero headroom.

Two consequences worth a look. A single child that ignores SIGHUP consumes the entire hook budget, so the afterEach times out at the same instant the grace expires and the rest of cleanup() — test-dir removal and the telemetry wait — never runs. And the wait loop is sequential, so the bound is per-session while the hook budget is per-hook: leaked sessions accumulate against one 10s ceiling rather than each getting its own.

The description's reasoning here addresses the CLI's ceiling ("deliberately above the CLI's own five-second shutdown ceiling") and says "hook time counts against the test timeout" — but in Vitest hooks are governed by hookTimeout, not testTimeout, and this config leaves it at the default. None of this is blocking: the measured reality is 35–42ms per session, the pathological case isn't one this suite produces, and a named hook timeout is a strictly better failure than today's silent whole-run EPIPE. But the exact collision looks unintentional, and any of these would close it — set hookTimeout in integration-tests/vitest.config.ts above the grace bound, drop the bound below the hook budget, or bound the aggregate wait instead of each session.

What I could not check

Whether node-pty can still deliver already-buffered onData after onExit fires. If it could, a single trailing process.stdout.write would remain theoretically possible after the wait resolves. node_modules is not installed in this review checkout so I could not read the package source, and I'm not going to guess at its read-loop ordering. Flagging it only to bound the claim, not as a defect — the sustained-writer case that was actually measured is closed either way.

Test evidence — this PR's own CI

I did not build or run any PR code; per the gate rules the review is static and the evidence below is this PR's own CI, read through the API at the reviewed commit.

The useful signal is that the strengthened regression test really ran and really passed: the Integration Tests (no-AK, No Sandbox) job invokes ./test-helper.test.ts explicitly and reports ✓ test-helper.test.ts (7 tests) 965ms, inside a job that finished Test Files 21 passed (21) / Tests 174 passed (174). That 965ms is doing real work as evidence — see the multi-listener point above.

The one red check is not this PR's. Dependency CVE audit failed on npm warn audit 503 Service Unavailable - POST https://registry.npmjs.org/-/npm/v1/security/audits/quick → npm error audit endpoint returned an error → exit 1. The npm registry's audit endpoint was down; this PR changes no dependency, no lockfile, and no manifest. I'm classifying that from the check's identity and the transport error in its own log, not from any claim in the PR. It does mean the Security Checks workflow is red on this commit, which matters for the deferred approval below.

The gap that CI cannot close: the job list on this commit contains no E2E Interactive - OpenTUI renderer (bun) leg, and tmux-testing and verify are both skipped. The file list that did run excludes interactive/** entirely. So the harness change is exercised in PR CI only by its own witness test — the suite that actually spawns and leaks PTY sessions, and the leg that actually reddens, are not run on pull requests at all. That is consistent with #10990 being filed per-commit against main, and the description is upfront that the OpenTUI leg "could not be run where this change was prepared" because bun was unavailable. Not verified: the OpenTUI/bun leg, and the sandbox:none shards — both absent from this commit's checks, the former also absent from the author's environment.

Sandboxed verification would settle this: @qwen-code /verify — the load-bearing claim is that no interactive PTY child outlives cleanup(), and this PR's CI substantiates it only through a stand-in script in the harness's own witness test. The real leg that reddens (E2E Interactive - OpenTUI renderer (bun)) does not run on pull requests, so nothing here observes the actual CLI child under bun/OpenTUI. An A/B against the base build is what would show the orphan that the description measured (ppid 2130 → 1) appearing on base and absent on this branch. The author has write access, so @qwen-code /tmux is also available if a real TUI session is wanted, though /verify is the better fit for a process-lifetime property.

代码审查

在读 diff 之前我先写下了自己的方案：在 spawn 时为每个 PTY 会话捕获一个 exit promise，在 cleanup() 里发完信号后等它，把上界设在高于 CLI 自身 5 秒关闭天花板的位置，确保这个上界用的 timer 不会撑住 worker 的事件循环，并且把 promise 记下来，好让测试自己已经关闭的会话立刻解除等待。这个 PR 五点全部做到了。它还独立地处理了我本来需要被说服才会想到的那个细节 —— 测试里的替身现在会先宣告 STAND_IN_READY，然后框架才被允许向它发信号，因为在 handler 装上之前发信号，子进程会以默认动作立刻死掉，什么都测不到。那正是让 #10971 "绿着"上线的那个洞，而把它在 witness 里堵上，才是让这个修复难以被悄悄撤销的关键。

所以：没有正确性阻塞项，没有安全问题，我找不到回归。机制是可靠的，我把那些"可能悄悄不生效"的地方都查了。

已验证的部分

• 同一个 pty 上两个 onExit 监听器。 diff 在已有的那个（用于 resolve promise）旁边又注册了一个 onExit，所以如果 node-pty 只认一个，那么要么新的等待、要么已有的退出码上报会静默失效。这里没问题 —— packages/core/src/services/shellExecutionService.ts 就并发注册了两个（1860 行和 2150 行），而且"每次注册返回一个 disposable"的签名正是数组式监听器的模式。CI 还给出了比我的阅读更好的经验证据：如果第二个注册把第一个覆盖掉了，exited 就永远不会 resolve，settleWithin 会烧掉完整的 10 秒 grace，test-helper.test.ts 不可能在 965ms 内跑完。而它跑完了，同时断言了 cleanupTookMs >= 750。这个等待是靠真实的 exit 事件解除的，不是靠超时。
• 不存在错过 exit 的竞态。 onExit 与 pty.spawn 在同一个同步 tick 内注册，所以子进程不可能在监听器装上之前就退出并被 reap。
• 已关闭的会话不产生代价。 promise 在 spawn 时捕获并存进被跟踪的条目里，所以测试自己关闭的会话，在 cleanup() splice 列表时早已 resolve。这正是 PR 关于 Ctrl+C 与 mid-turn quit 用例的说法成立的原因，也是这个改动不会拖慢本来就行为良好的测试的原因。
• settleWithin 不会让 teardown 新增失败。 竞态的两条路径都是 resolve 而不是 reject，且两条路径都会 clearTimeout。对清理路径来说这是正确的选择 —— 一个会抛错的上界会把"泄漏了一个子进程"变成"测试失败"。
• 没有东西撑着事件循环。 timer.unref() 加上两条路径都执行的 clearTimeout。注释把 unref 的必要性说得略重了（子进程活着时 node-pty 自己的 handle 就在撑着循环，timer 无论如何都会触发），但它无害，而且对于运行在 worker 拆除期间的代码来说这个直觉是对的。

一条建议 —— grace 上界与 hook 预算精确相撞

INTERACTIVE_EXIT_GRACE_MS 是 10_000。cleanup() 在整个 interactive 套件里都是从 afterEach 调用的（hooks-command、context-compress-interactive、mid-turn-submit-interactive、external-context-* 等），而 integration-tests/vitest.config.ts 把 testTimeout 设成 5 分钟，却从未设置 hookTimeout —— 它是仓库里唯一一个不设置的 vitest 配置。其它每个 package 都是刻意钉住的（packages/cli、packages/core、packages/web-shell、packages/acp-bridge、packages/node-repl、packages/qwen-live、packages/sdk-typescript 设成 10000）。所以真正管着 afterEach 的那个 hook 跑在 Vitest 文档默认的 10 秒上 —— 与 grace 上界是同一个数字，一点余量都没有。

有两个后果值得看一眼。一个完全忽略 SIGHUP 的子进程会吃光整个 hook 预算，于是 afterEach 会在 grace 到期的同一刻超时，而 cleanup() 剩下的部分 —— 测试目录清理和 telemetry 等待 —— 就再也不会执行。而且等待循环是串行的，所以上界是"每会话"的，hook 预算却是"每 hook"的：泄漏的会话会累积去撞同一个 10 秒天花板，而不是各自拥有自己的上界。

描述里针对这一点的推理讲的是 CLI 的天花板（"刻意设在高于 CLI 自身五秒关闭天花板的位置"），并说"hook 时间是计入测试超时的" —— 但在 Vitest 里 hook 由 hookTimeout 管，不是 testTimeout，而这个配置把它留在了默认值上。这些都不构成阻塞：实测是每会话 35–42 毫秒，那种病态情况不是本套件会产生的，而一个有名字的 hook 超时，严格好于今天这种静默的整 run EPIPE。但这个精确相撞看起来是无意的，以下任一做法都能解决 —— 在 integration-tests/vitest.config.ts 里把 hookTimeout 设到 grace 上界之上、把上界降到 hook 预算之下，或者对累计等待设上界而不是对每个会话。

我无法确认的部分

node-pty 是否可能在 onExit 触发之后，仍然投递已经缓冲的 onData。如果可能，那么在等待解除之后，理论上仍会剩下一次尾随的 process.stdout.write。这个审查 checkout 里没有安装 node_modules，所以我读不到该包的源码，我也不打算去猜它读取循环的顺序。写出来只是为了给结论划个边界，不是当作缺陷 —— 那个被实测到的"持续写入者"场景，无论哪种情况都已经被关掉了。

测试证据 —— 本 PR 自己的 CI

我没有构建或运行任何 PR 代码；按 gate 规则，审查是静态的，下面的证据是本 PR 自己的 CI，通过 API 在被审查的 commit 上读取的。

有用的信号是：加强后的回归测试确实跑了、也确实过了。Integration Tests (no-AK, No Sandbox) 这个 job 显式调用了 ./test-helper.test.ts，报告 ✓ test-helper.test.ts (7 tests) 965ms，而整个 job 收尾于 Test Files 21 passed (21) / Tests 174 passed (174)。那个 965ms 本身就是有分量的证据 —— 见上面多监听器那一点。

唯一变红的检查不是这个 PR 造成的。Dependency CVE audit 失败于 npm warn audit 503 Service Unavailable - POST https://registry.npmjs.org/-/npm/v1/security/audits/quick → npm error audit endpoint returned an error → exit 1。npm registry 的 audit 端点挂了；本 PR 没有改动任何依赖、lockfile 或 manifest。我是根据这个检查的身份和它自己日志里的传输层错误来归类的，不是根据 PR 里的任何说法。这确实意味着 Security Checks workflow 在本 commit 上是红的，而这对下面的延迟批准有影响。

CI 关不掉的那个缺口：本 commit 的检查列表里没有 E2E Interactive - OpenTUI renderer (bun) 这个 leg，而且 tmux-testing 和 verify 都是 skipped。真正跑了的那个文件列表完全不含 interactive/**。所以 harness 改动在 PR CI 里只被它自己的 witness 测试覆盖 —— 真正 spawn 并泄漏 PTY 会话的那个套件、以及真正变红的那个 leg，在 pull request 上根本不跑。这与 #10990 是按 commit 针对 main 创建的相一致，描述也坦白说 OpenTUI leg "在准备这一改动的环境里无法运行"，因为那里没有 bun。未验证：OpenTUI/bun leg，以及 sandbox:none 各 shard —— 两者都不在本 commit 的检查里，前者在作者的环境中同样缺失。

（CI 表格见上，未重复翻译。）

沙箱验证可以定这件事：@qwen-code /verify —— 承重的主张是"没有任何交互式 PTY 子进程比 cleanup() 活得更久"，而本 PR 的 CI 只通过 harness 自己 witness 测试里的一个替身脚本来支撑它。真正变红的那个 leg（E2E Interactive - OpenTUI renderer (bun)）在 pull request 上不跑，所以这里没有任何东西观察到 bun/OpenTUI 下真实的 CLI 子进程。与 base build 做 A/B 才能显示出描述里实测到的那个孤儿进程（ppid 2130 → 1）在 base 上出现、在本分支上消失。作者有 write 权限，所以如果想要一个真实的 TUI 会话，@qwen-code /tmux 也可用，不过对于"进程生命周期"这类性质，/verify 更合适。

Confidence: 4/5 — the fix is correct, cheap, and witnessed; the only things keeping it from 5 are a bound that collides exactly with the hook budget, and a leg-level claim no pull-request CI can substantiate.

Stepping back: my independent proposal and this PR landed in the same place on all five points I'd have insisted on, and it beat me on one — the readiness handshake in the stand-in. I'd have written the wait, bounded it, and unref'd the timer; I'm not sure I'd have noticed that a signal delivered before the handler exists measures nothing, which is the exact reason the previous fix shipped green. That detail is the difference between a regression test that passes and one that actually pins the property.

The strongest objection I can mount is that this PR does not prove the OpenTUI leg stops reddening — and the author says so first, in more places than I would have. But that's an argument about the cure, not the change. What the change does claim, I could verify: the harness really does forward every PTY byte to process.stdout under KEEP_OUTPUT, a signalled child really is still alive when kill() returns, and awaiting the exit event really does close that window. The cost is ~38ms on the one file that leaks, and the worst case moves from "silent whole-run failure naming no test" to "a named hook timeout". Turning down a bounded, correct fix because it isn't a complete cure would be the wrong call.

Six months from now I'd thank whoever wrote this. The comments carry the why that isn't recoverable from the code — the CLI's 5s shutdown ceiling as the reason for the bound's magnitude, and the reason the stand-in needs a signal handler at all. The test was strengthened in place instead of duplicated, and the description records why the earlier witness failed, which is the part that stops this regressing quietly.

Two things I'd want the author or a maintainer to weigh, neither blocking:

• The 10s grace bound equals Vitest's default hookTimeout, and integration-tests/vitest.config.ts is the only vitest config in the repo that doesn't set it. Since the wait loop is sequential, the bound is per-session but the hook budget is per-hook. Detail and three possible fixes are in the Stage 2 comment.
• This is an autofix against a maintainer-approved issue (autofix/approved), and the description is unusually thorough. I treated that as no evidence either way and checked the load-bearing claims against the harness source and this commit's CI instead — they held, including one I verified better than by reading: test-helper.test.ts finished in 965ms while asserting a ≥750ms wait, which is only possible if the new exit listener actually fires.

On the approval: CI is still running (Qwen Code CI in progress — Lint & Static and Test (ubuntu-latest)), so I'm not approving in this run; approval is deferred until CI lands green on the commit below.

⚠️ Maintainers, this deferral probably will not resolve itself. Dependency CVE audit is already red on this commit because the npm registry's audit endpoint returned 503 — pre-existing infra noise, unrelated to a PR that touches no dependency. The finalize step only approves once every check on the commit is green, so that red check will most likely withhold the deferred approval even after the two running jobs pass. Remedy is a human one: re-run the CVE audit once the registry recovers, or approve directly. Flagging it so a green suite doesn't sit here waiting on a check that will never turn green on its own.

中文说明

Confidence: 4/5 —— 修复是正确、廉价且有 witness 的；让它到不了 5 分的只有两件事：一个与 hook 预算精确相撞的上界，以及一个任何 pull-request CI 都无法支撑的 leg 级主张。

退一步看：我自己独立想到的方案与这个 PR 在我会坚持的全部五点上都落在同一处，而它在一点上胜过我 —— 替身的就绪握手。我会写等待、给它设上界、把 timer unref 掉；但我不确定我会注意到"在 handler 装上之前发信号，什么都测不到"，而那恰恰是上一次修复"绿着"上线的原因。这个细节，正是"一个能通过的回归测试"与"一个真正钉住性质的回归测试"之间的区别。

我能提出的最有力反对是：这个 PR 并没有证明 OpenTUI leg 不再变红 —— 而作者比我更主动地、在更多地方先说了这一点。但那是关于"疗效"的论证，不是关于"改动"的。改动所声称的部分，我都能验证：harness 确实在 KEEP_OUTPUT 下把每一个 PTY 字节转发到 process.stdout；被发过信号的子进程在 kill() 返回时确实仍然活着；而等待 exit 事件确实关掉了那个窗口。代价是那个唯一泄漏会话的文件增加约 38 毫秒，最坏情况从"静默的整 run 失败、不指出任何测试"变成"一个有名字的 hook 超时"。因为一个有界的、正确的修复不是彻底的疗效就把它拒掉，是错误的判断。

六个月后我会感谢写这段代码的人。注释承载了那些无法从代码里恢复的为什么 —— CLI 的 5 秒关闭天花板是上界取值的理由，以及替身为什么必须有一个信号 handler。测试是就地加强的而不是复制一份，而描述记录了早先那个 witness 为什么失效，那正是防止这件事悄悄退化的部分。

有两点我希望作者或维护者权衡，都不构成阻塞：

• 10 秒的 grace 上界等于 Vitest 的默认 hookTimeout，而 integration-tests/vitest.config.ts 是仓库里唯一不设置它的 vitest 配置。由于等待循环是串行的，上界是"每会话"的，而 hook 预算是"每 hook"的。细节与三种可能的修法在 Stage 2 评论里。
• 这是针对一个维护者已批准的 issue（autofix/approved）的 autofix，而且描述异常详尽。我对此不取任何立场，而是把承重的主张拿去对照 harness 源码和本 commit 的 CI —— 它们都成立，其中一条我验证得比阅读更好：test-helper.test.ts 在 965ms 内跑完，同时断言了一次 ≥750ms 的等待，而这只在新的 exit 监听器确实触发时才可能。

关于批准： CI 仍在运行（Qwen Code CI 进行中 —— Lint & Static 与 Test (ubuntu-latest)），所以本次运行我不批准；批准被延迟到下面这个 commit 的 CI 变绿之后。

⚠️ 维护者请注意，这个延迟很可能不会自行解除。 Dependency CVE audit 在本 commit 上已经是红的，原因是 npm registry 的 audit 端点返回了 503 —— 属于既有的基础设施噪声，与一个不碰任何依赖的 PR 无关。finalize 步骤只会在该 commit 上每一个检查都变绿之后才批准，所以即使那两个正在运行的 job 通过了，那个红色检查也很可能会让延迟批准被扣住。补救办法是人工的：等 registry 恢复后重跑 CVE audit，或者直接批准。把它标出来，是为了不让一套绿色的检查在这里干等一个永远不会自己变绿的检查。

[Suggestion] R1-2: settleWithin is the repo's third promise-vs-setTimeout racer and a semantic twin of withTimeout in packages/cli/src/utils/cleanup.ts:44 — settle-on-timeout semantics that now live in independent copies across the production/test boundary, with a reject-on-timeout sibling at integration-tests/qwen-live-harness.ts:96. If the CLI's exit bound or timer hygiene ever changes, the twin here does not move with it, and the next teardown-timing fix (this class already recurred as #10969 then #10990) must rediscover and re-patch up to three sites. Neither existing helper is cleanly reusable — the exact twin is module-private production source, and the importable one rejects on timeout and drags a heavy import graph — so keeping the local 12-line helper is defensible under simplicity-first; this is awareness for whoever next touches either bound.

Witness:

witness: not run — quality/duplication claim settled by reading the three
definitions at the cited lines (cleanup.ts:44, qwen-live-harness.ts:96,
test-helper.ts:135); no run capability produces "future drift"

Note: OVERALL_CLEANUP_TIMEOUT_MS = 5_000 at packages/cli/src/utils/cleanup.ts:36 — any restructuring must keep INTERACTIVE_EXIT_GRACE_MS above the CLI's overall exit-cleanup bound, as the added comment above this function relies on.

中文说明

settleWithin 是仓库中第三个 promise 与 setTimeout 的竞速器，与 packages/cli/src/utils/cleanup.ts:44 的 withTimeout 语义相同 —— “超时即安顿”的语义如今跨生产/测试边界存在独立拷贝，另有 integration-tests/qwen-live-harness.ts:96 的超时即 reject 版本。若 CLI 的退出上限或 timer 清理方式发生变化，这里的孪生实现不会同步，下一次 teardown 时序修复（此类问题已先后以 #10969、#10990 复现）将不得不重新发现并修补多达三处。两个现有助手均不可干净复用 —— 完全同构的那份是生产代码的模块私有函数，可导入的那份超时即 reject 且拖入沉重的依赖图 —— 因此按简洁优先原则保留本地 12 行助手是可以辩护的；此条用于提醒后续触碰任一上限的人。

注意：packages/cli/src/utils/cleanup.ts:36 处 OVERALL_CLEANUP_TIMEOUT_MS = 5_000 —— 任何重构都必须保持 INTERACTIVE_EXIT_GRACE_MS 高于 CLI 的整体退出清理上限（本函数上方的注释即依赖于此）。

[qwen-code-dev-bot]

Declined — no code change this round.

The observation is accurate: settleWithin is a semantic twin of withTimeout at packages/cli/src/utils/cleanup.ts:44, with a reject-on-timeout sibling at integration-tests/qwen-live-harness.ts:96. It also already reaches the conclusion I would act on — the exact twin is module-private production source, and the importable one rejects on timeout and drags a heavy import graph into a teardown helper — so neither is cleanly reusable and the local helper stands under simplicity-first.

Consolidating would mean exporting a private production helper for a test harness to consume, or moving it into a shared module both sides import. Either is a cross-boundary refactor well outside this PR's footprint of two integration-test files, so I left the code as-is. The drift risk the note points at is recorded where it bites: the comment above INTERACTIVE_EXIT_GRACE_MS names the 5s runExitCleanup() bound the grace must stay above.

中文说明

已婉拒 —— 本轮不做代码改动。

该观察属实：settleWithin 与 packages/cli/src/utils/cleanup.ts:44 的 withTimeout 语义相同，另有 integration-tests/qwen-live-harness.ts:96 的超时即 reject 版本。它本身也已给出我会采纳的结论 —— 完全同构的那份是生产代码的模块私有函数，可导入的那份超时即 reject 且会把沉重的依赖图拖进 teardown 助手 —— 因此两者都无法干净复用，按简洁优先原则保留本地这份助手。

若要合并，就必须把一个私有的生产助手导出给测试框架使用，或将其移到双方都能 import 的共享模块。任一做法都属于跨边界重构，远超本 PR 只涉及两个集成测试文件的范围，因此代码保持原样。该提醒所指的漂移风险已记录在真正会出问题的位置：INTERACTIVE_EXIT_GRACE_MS 上方的注释写明了宽限必须高于 runExitCleanup() 的 5 秒上限。

🤖 Addressed the latest review feedback (round 1/10). What changed, and what I pushed back on: · 已处理最新评审反馈（第 1/10 轮）。改动内容与我反驳保留之处如下：

Autofix round: review feedback on PR #11001 (issue #10990)

Commit 01b7633dc0 — test(integration): shrink the cleanup grace and warn when it expires (#10990). Two files, +109 / −52, all inside the PR's existing footprint (integration-tests/). No conflict merge was needed (--conflict false).

Five of the six inline findings were reproduced first and then fixed; one was declined with its reason posted on its own thread. Nothing was deferred to the follow-up queue, and no finding needed a maintainer's decision.

Feedback dispositions

R1-1 [rc:3931466680] — grace equals vitest's default hookTimeout → Implemented

Verified before changing anything: the installed vitest is 3.2.7 and resolves hookTimeout ??= 1e4 (node_modules/vitest/dist/chunks/coverage.DfSpMS-b.js:3922); integration-tests/vitest.config.ts sets testTimeout (5 min) but no hookTimeout; and cleanup() is awaited from afterEach hooks across the interactive suites (e.g. integration-tests/interactive/file-system-interactive.test.ts:31), where it shares the 10s hook budget with fakeServer?.close() and the no-proxy restore. A fully expired 10s grace therefore did eat the whole hook.

Took the constant option rather than adding hookTimeout to the vitest config: INTERACTIVE_EXIT_GRACE_MS is now 8_000, one line, no new config surface, and still above the CLI's own 5s runExitCleanup() ceiling (packages/cli/src/utils/cleanup.ts:36). The comment above the constant now names both bounds, since either direction is a silent regression.

Disclosure: this one is a constant, not a guard or branch, so it has no mutation witness in the tests — its two bounds are pinned by that comment instead. Everything else below is witnessed.

R1-2 [rc:3931466693] — third promise-vs-timer racer → Declined (thread left open, reply posted)

The observation is accurate, and it already reaches the conclusion I would act on: the exact twin (withTimeout, packages/cli/src/utils/cleanup.ts:44) is module-private production source, and the importable sibling (integration-tests/qwen-live-harness.ts:96) rejects on timeout and pulls a heavy import graph into a teardown helper. Consolidating means exporting a private production helper for a test harness, or moving it into a shared module both sides import — a cross-boundary refactor well outside a two-file integration-test PR. The finding is awareness, not a requested change, so the code stands.

R1-3 [rc:3931466699] — timeout arm of settleWithin had no test → Implemented

Reproduced first: with the timeout arm deleted, the pre-round suite stayed green at 7 passed / 1015ms. New case stops waiting for an interactive child that never exits uses a stand-in that traps SIGHUP as a no-op and asserts cleanup() still returns inside a bounded window.

Took the reviewer's second option (accept the ~8s run) over making the grace injectable: an injectable grace is a test-only knob on a harness ~20 suites consume, and it would have been the round's only production-API growth. The new case SIGKILLs the stand-in in a finally, because cleanup() has by design given up on it and the rig no longer tracks it — confirmed no orphaned stand-in survives a green run.

R1-4 [rc:3931466703] — grace expiry resolved silently → Implemented

settleWithin now resolves true when the promise settles and false when the timer wins, and cleanup() warns with ptyProcess.pid and the grace it exhausted. exited stays resolve-only as the finding required, so no test that never hits the timeout grows an unhandled rejection. The warning is deliberately not behind VERBOSE: the point is that oncall sees it in the failing run.

R1-6 [rc:3931466715] — regression test assumed the bundle lane → Implemented

Reproduced first: with INTEGRATION_TEST_USE_INSTALLED_GEMINI=true, the pre-round test failed at 30159ms with expected false to be true (qwen is installed on this runner, so the spawn succeeded and ran the real CLI instead of the stand-in). Both stand-in cases now use it.skipIf(usesInstalledCli) keyed off that exact variable and value, matching the repo's existing it.skipIf(...) formatting — the new R1-3 case drives rig.bundlePath too, so it needs the same skip. After the fix that lane reports 6 passed | 2 skipped.

Declined the optional win32 half of the suggestion: no CI lane runs the integration suites on Windows (ci.yml integration_no_ak and integration_cli both pin ubuntu_runner; e2e.yml runs ubuntu, self-hosted linux and macos), so there is no evidence of a win32 failure to guard, and SIGHUP trapping is POSIX so the macOS lane behaves like Linux.

R1-7 [rc:3931466719] — duration assertion was lower-bounded only → Implemented

Reproduced first: with exited mutated to never settle, the pre-round test passed green at 10207ms versus 965ms intact, so the onExit wiring added by this PR was unwitnessed. Added expect(cleanupTookMs).toBeLessThan(5_000).

One deviation worth recording: I first bounded it by INTERACTIVE_EXIT_GRACE_MS to avoid a bare literal, and the mutant then failed by a 0ms margin — expected 8000 to be less than 8000 — one clock truncation away from passing silently. The reviewer's 5_000 leaves a 3s discriminator margin while staying 4s above the intact ~980ms, so I kept it and said why in the comment.

Review bodies [rv:5109876141], [rv:5110629962] — partial-review disclosures

No new findings (round 2 posted 0 and confirmed 4 already reported). Their disclosed gap — "Integration Tests (CLI, No Sandbox) was skipped in CI" — is the API-key lane, which is not runnable here. I substituted the closest available real-CLI evidence for the grace change: integration-tests/interactive/file-system-interactive.test.ts drives the built bundle through a real PTY against the fake model server and awaits rig.cleanup() in afterEach, which is exactly the path the 10s→8s change affects. It passed in 6097ms with no hook timeout.

Failed check: Dependency CVE audit

Not caused by this PR, and not fixable inside it. Evidence rather than assumption:

• The job's only inputs are .nvmrc, package-lock.json, packages/*/package-lock.json, and the live advisory database (.github/workflows/security-checks.yml:28-64). There is no baseline or allowlist file — scripts/tests/security-workflows.test.js:80-95 pins it as a hard gate.
• git diff --name-only HEAD origin/main -- '*package-lock.json' '*package.json' '.nvmrc' returns empty: this branch and current main carry byte-identical dependency manifests and lockfiles, so the audit resolves the same tree it would resolve on main today.
• The PR's entire contribution is the two integration-tests/ files above (git diff --name-only $(git merge-base origin/main HEAD) HEAD).

The only fix is a lockfile bump, which is a supply-chain area this round must not touch and which sits outside the PR's footprint. It needs a maintainer or a dedicated dependency PR. I did not run npm audit — it is a networked package command and not among the trusted checks for this workflow — so I am reporting the attribution evidence rather than a reproduced advisory list.

Verification

Required gates (all actually run, all green):

• npm run build — passed (BUILD_EXIT=0; scripts/build.js builds only packages/*, and this round changes no package source)
• npm run typecheck — passed (TYPECHECK_EXIT=0, includes typecheck:integration)
• npm run lint — passed (LINT_EXIT=0, includes eslint integration-tests)
• npm run typecheck:integration — passed, re-run after the final test edit
• npx prettier --check integration-tests/test-helper.ts integration-tests/test-helper.test.ts — "All matched files use Prettier code style!"
• vitest run --root ./integration-tests ./test-helper.test.ts — 8 passed (8) on the committed tree (was 7 pre-round); stops waiting for an interactive child that never exits 8205ms, waits for an interactive session a test never closed to end 982ms
• vitest run --root ./integration-tests ./interactive/file-system-interactive.test.ts — 1 passed, 6097ms (real CLI bundle through a PTY, cleanup() in afterEach)
• No orphaned stand-in processes after any green run (ps sweep for never-exit-cli / slow-exit-cli)
• git status --short clean after commit; only the two intended files in it

Mutation probes (each new guard/branch has its own witness; pre-round = gap reproduced, post-round = guard caught):

Probe	Mutation	Pre-round	Post-round
A	exited never settles (new Promise<void>(() => {}))	green at 10207ms	RED — expected 8002 to be less than 5000
A-intermediate	same, bound = grace	—	RED but by 0ms — expected 8000 to be less than 8000 → bound widened to 5_000
B	settleWithin timeout arm removed	green, 7 passed / 1015ms	RED — Test timed out in 20000ms on the new case
C	console.warn branch removed	n/a (branch did not exist)	RED — expected '' to contain '3754' (pid)
D	none — INTEGRATION_TEST_USE_INSTALLED_GEMINI=true	RED at 30159ms	green, 6 passed | 2 skipped

Every mutation was reverted and the tree re-verified green afterwards. The one leftover orphan from probe B (whose hang means the finally never runs) was killed and is not part of the committed state.

Not run: npm audit (networked, untrusted for this workflow), the API-key cli / interactive CI lanes (no credentials), and any settings-schema regeneration (no settings source touched).

Autofix 轮次：PR #11001（issue #10990）的评审反馈

提交 01b7633dc0 —— test(integration): shrink the cleanup grace and warn when it expires (#10990)。两个文件，+109 / −52，全部落在本 PR 既有的范围内（integration-tests/）。本轮无需合并基线分支（--conflict false）。

六条行内发现中，五条先复现再修复；一条婉拒，理由已回复在其对应的评论串上。没有任何发现被转入后续队列，也没有需要维护者裁决的事项。

反馈处理结论

R1-1 [rc:3931466680] —— 宽限恰好等于 vitest 默认 hookTimeout → 已实施

改动前先核实：当前安装的 vitest 为 3.2.7，其解析逻辑为 hookTimeout ??= 1e4（node_modules/vitest/dist/chunks/coverage.DfSpMS-b.js:3922）；integration-tests/vitest.config.ts 只设置了 testTimeout（5 分钟）而没有 hookTimeout；并且各 interactive 套件都在 afterEach 钩子里 await cleanup()（例如 integration-tests/interactive/file-system-interactive.test.ts:31），它要与 fakeServer?.close() 和 no-proxy 还原共享这 10 秒钩子预算。因此宽限一旦耗尽，确实会吃满整个钩子。

选择改常量而不是在 vitest 配置里加 hookTimeout：INTERACTIVE_EXIT_GRACE_MS 现为 8_000，只改一行，不增加配置面，同时仍高于 CLI 自身 5 秒的 runExitCleanup() 上限（packages/cli/src/utils/cleanup.ts:36）。该常量上方的注释现在同时写明这两个边界，因为往任一方向改动都是静默回归。

需要说明：这一条是常量而非守卫或分支，因此它在测试中没有变异 witness —— 它的两个边界由上述注释固定。以下其余各条都有 witness。

R1-2 [rc:3931466693] —— 仓库中第三个 promise 与 timer 竞速器 → 已婉拒（评论串保持 open，已回复）

该观察属实，而且它本身已给出我会采纳的结论：完全同构的那份（withTimeout，packages/cli/src/utils/cleanup.ts:44）是生产代码的模块私有函数，可导入的那份（integration-tests/qwen-live-harness.ts:96）超时即 reject，并会把沉重的依赖图拖进一个 teardown 助手。要合并就意味着把私有的生产助手导出给测试框架使用，或将其移到双方都能 import 的共享模块 —— 这属于跨边界重构，远超一个只改两个集成测试文件的 PR。该条是提醒而非要求改动，因此代码保持原样。

R1-3 [rc:3931466699] —— settleWithin 的超时分支没有测试 → 已实施

先复现：删掉超时分支后，改动前的套件仍全绿，7 passed / 1015ms。新增用例 stops waiting for an interactive child that never exits，其替身把 SIGHUP 捕获为空操作，断言 cleanup() 仍在有界窗口内返回。

采纳评审给出的第二个选项（接受约 8 秒的运行时间），而没有把宽限改成可注入：可注入的宽限是一个仅供测试使用的旋钮，而这个 harness 被约 20 个套件消费，它会是本轮唯一的生产 API 增长。新用例在 finally 里对替身执行 SIGKILL，因为 cleanup() 按设计已放弃它、rig 也不再跟踪它 —— 已确认绿色运行后不会残留孤儿替身进程。

R1-4 [rc:3931466703] —— 宽限到期时静默 resolve → 已实施

settleWithin 现在在 promise 落定时 resolve true、在计时器获胜时 resolve false，cleanup() 会输出带 ptyProcess.pid 和所耗尽宽限值的警告。按该发现的要求，exited 保持只 resolve，因此未触发超时的测试不会多出未处理 rejection。该警告刻意不放在 VERBOSE 之后：要点正是让值班人员在失败的那次运行里看到它。

R1-6 [rc:3931466715] —— 回归测试假定了 bundle 通道 → 已实施

先复现：设置 INTEGRATION_TEST_USE_INSTALLED_GEMINI=true 后，改动前的测试在 30159ms 处以 expected false to be true 失败（本机装有 qwen，所以 spawn 成功但运行的是真实 CLI 而非替身）。两个替身用例现在都使用 it.skipIf(usesInstalledCli)，条件精确取自该变量与取值，格式沿用仓库既有的 it.skipIf(...) 写法 —— 新增的 R1-3 用例同样通过 rig.bundlePath 驱动，因此需要相同的跳过。修复后该通道报告 6 passed | 2 skipped。

婉拒该建议中可选的 win32 部分：没有任何 CI 通道在 Windows 上运行集成套件（ci.yml 的 integration_no_ak 与 integration_cli 都固定为 ubuntu_runner；e2e.yml 运行 ubuntu、self-hosted linux 和 macos），因此没有任何 win32 失败证据支持加这层防护；而且捕获 SIGHUP 属于 POSIX 行为，macOS 通道与 Linux 表现一致。

R1-7 [rc:3931466719] —— 时长断言只有下限 → 已实施

先复现：把 exited 变异为永不 settle 后，改动前的测试在 10207ms 通过（完好时 965ms），说明本 PR 新增的 onExit 接线没有 witness。已加入 expect(cleanupTookMs).toBeLessThan(5_000)。

有一处偏离值得记录：我最初用 INTERACTIVE_EXIT_GRACE_MS 作为上限以避免裸字面量，结果变异体只以 0 毫秒的余量失败 —— expected 8000 to be less than 8000 —— 只差一次时钟截断就会静默通过。评审建议的 5_000 既留出 3 秒的判别余量，又比完好时的约 980ms 高出 4 秒，因此保留该值并在注释中说明原因。

评审正文 [rv:5109876141]、[rv:5110629962] —— 部分审查的缺口披露

没有新发现（第 2 轮 posted 0，并确认 4 条已报告过）。其披露的缺口 —— “Integration Tests (CLI, No Sandbox) was skipped in CI” —— 是需要 API key 的通道，本机无法运行。针对宽限改动，我用了最接近的真实 CLI 证据替代：integration-tests/interactive/file-system-interactive.test.ts 通过真实 PTY 驱动已构建的 bundle、对接 fake model server，并在 afterEach 中 await rig.cleanup()，正是 10s→8s 改动所影响的路径。它以 6097ms 通过，没有出现钩子超时。

失败检查：Dependency CVE audit

不是本 PR 造成的，也无法在本 PR 内修复。以下是证据而非假设：

• 该 job 的输入只有 .nvmrc、package-lock.json、packages/*/package-lock.json 和实时漏洞数据库（.github/workflows/security-checks.yml:28-64）。没有任何基线或白名单文件 —— scripts/tests/security-workflows.test.js:80-95 把它固定为硬门禁。
• git diff --name-only HEAD origin/main -- '*package-lock.json' '*package.json' '.nvmrc' 返回空：本分支与当前 main 的依赖清单和 lockfile 完全逐字节相同，因此该审检查解析出的依赖树与今天在 main 上解析出的相同。
• 本 PR 的全部改动就是上面那两个 integration-tests/ 文件（git diff --name-only $(git merge-base origin/main HEAD) HEAD）。

唯一的修法是升级 lockfile，而那属于本轮不得触碰的供应链区域，也在本 PR 范围之外。需要维护者或一个专门的依赖升级 PR 处理。我没有运行 npm audit —— 它是联网的包管理命令，不在本工作流的可信命令清单内 —— 因此我给出的是归因证据，而不是复现出的漏洞条目列表。

验证

必需的门禁（全部真实执行，全部通过）：

• npm run build —— 通过（BUILD_EXIT=0；scripts/build.js 只构建 packages/*，本轮未改动任何 package 源码）
• npm run typecheck —— 通过（TYPECHECK_EXIT=0，含 typecheck:integration）
• npm run lint —— 通过（LINT_EXIT=0，含 eslint integration-tests）
• npm run typecheck:integration —— 通过，在最后一次测试文件编辑后重跑
• npx prettier --check integration-tests/test-helper.ts integration-tests/test-helper.test.ts —— “All matched files use Prettier code style!”
• vitest run --root ./integration-tests ./test-helper.test.ts —— 在已提交的代码树上 8 passed (8)（改动前为 7）；stops waiting for an interactive child that never exits 8205ms，waits for an interactive session a test never closed to end 982ms
• vitest run --root ./integration-tests ./interactive/file-system-interactive.test.ts —— 1 passed，6097ms（真实 CLI bundle 经 PTY，cleanup() 位于 afterEach）
• 任何绿色运行之后都没有残留的替身进程（用 ps 扫描 never-exit-cli / slow-exit-cli）
• 提交后 git status --short 干净；提交中只含两个预期文件

变异探针（每个新增守卫/分支都有自己的 witness；改动前 = 复现缺口，改动后 = 守卫捕获）：

探针	变异内容	改动前	改动后
A	exited 永不 settle（new Promise<void>(() => {})）	绿，10207ms	红 —— expected 8002 to be less than 5000
A-中间态	同上，上限取宽限值	——	红但仅差 0ms —— expected 8000 to be less than 8000 → 上限放宽为 5_000
B	移除 settleWithin 的超时分支	绿，7 passed / 1015ms	红 —— 新用例 Test timed out in 20000ms
C	移除 console.warn 分支	不适用（该分支当时不存在）	红 —— expected '' to contain '3754'（pid）
D	无变异 —— 设置 INTEGRATION_TEST_USE_INSTALLED_GEMINI=true	红，30159ms	绿，6 passed | 2 skipped

每次变异之后都已还原，并重新验证代码树为绿。探针 B 遗留的那一个孤儿进程（挂起意味着 finally 不会执行）已被 kill，不属于已提交的状态。

未运行：npm audit（联网命令，本工作流不采信）、需要 API key 的 cli / interactive CI 通道（无凭据）、以及任何 settings schema 重新生成（未改动 settings 源）。

🤖 Addressed the latest review feedback (round 2/10). What changed, and what I pushed back on: · 已处理最新评审反馈（第 2/10 轮）。改动内容与我反驳保留之处如下：

Autofix round summary — PR #11001 (issue #10990)

One actionable finding this round, plus one failed check. The finding is implemented and witnessed; the failed check is diagnosed below and is not attributable to this PR.

Commit: 2e6c42e36a — test(integration): pin the exit grace to literal bounds (#10990) (1 file changed, 5 insertions).

Feedback addressed

[rc:3933513088] and [rc:3934197269] — R3-1 [Suggestion]: INTERACTIVE_EXIT_GRACE_MS is pinned by its comment alone → Implemented

Both inline comments are the same finding (round 3 and its round-4 carry-forward); one change resolves both, so both threads are listed as resolved.

Reproduced before changing anything. I ran the reviewer's mutation probe against the pre-round code:

INTERACTIVE_EXIT_GRACE_MS	test-helper.test.ts before the fix
8_000 (as committed)	8 passed
3_000 — below the CLI's 5s exit-cleanup ceiling, i.e. the retune that re-opens #10990	8 passed (gap reproduced)
15_000 — above vitest's 10s default hookTimeout	8 passed (gap reproduced)

This confirms the premise: the only assertion touching the constant was expect(cleanupTookMs).toBeLessThan(INTERACTIVE_EXIT_GRACE_MS + 5_000), derived from the constant itself, so it retunes together with the value it should police.

Verified the two bounds the comment names instead of taking them on faith:

• Floor: OVERALL_CLEANUP_TIMEOUT_MS = 5_000 at packages/cli/src/utils/cleanup.ts:36.
• Ceiling: vitest resolves hookTimeout ??= browser.enabled ? 3e4 : 1e4 (node_modules/vitest/dist/chunks/coverage.DfSpMS-b.js:3922), and integration-tests/vitest.config.ts sets testTimeout but no hookTimeout, so the default 10s applies to the afterEach callers.

Change — 5 lines in integration-tests/test-helper.test.ts, inside the never-exit case this PR already added: two literal-bound assertions plus a comment saying why they are literals rather than derived. No production code changed; integration-tests/test-helper.ts is byte-identical to the pre-round head.

Fix witness — the same probe re-run after the change, restoring test-helper.ts byte-identically after each mutant (verified by an empty git diff):

INTERACTIVE_EXIT_GRACE_MS	result after the fix
3_000	1 failed | 7 passed — expected 3000 to be greater than 5000
1_000	1 failed | 7 passed — expected 1000 to be greater than 5000
15_000	1 failed | 7 passed — expected 15000 to be less than 10000
8_000 (restored)	8 passed

Both directions the reviewer named now turn the suite red, and each added assertion is individually load-bearing: dropping the floor assertion returns 3_000/1_000 to green, dropping the ceiling assertion returns 15_000 to green.

Placement note. The pin sits inside it.skipIf(usesInstalledCli), matching the reviewer's suggested location. Nothing under .github/workflows/ sets INTEGRATION_TEST_USE_INSTALLED_GEMINI, so the pin runs in every CI lane that runs this file, including the no-AK lane. Lifting it out of the skipIf would start addressing the round-4 deferred item "installed-release lane loses its only cleanup witness", which this round was explicitly not asked to touch.

Recorded, not requested — no action taken

Both review bodies carry qwen-review-deferred lists marked "recorded, not requested in this round" (1 item in round 3, 5 in round 4: the sequential per-child grace wait, the duplicate onExit wrapper, InteractiveSession.close() signalling without waiting, the bare 5_000 bound, the installed-release lane witness, and the never-exit stand-in leak). I left all of them alone to keep this round inside its ask. The growth window was at 0/400 source and 0/400 test net lines; this round adds 5 test lines and 0 source lines.

Failed check: Test (ubuntu-latest, Node 22.x) — diagnosed, not attributable to this PR

What that job actually runs

Two commands (ci.yml:756 and ci.yml:759): npm run test:ci:workspaces -- --retry=2, then, only if that passes, npm run test:scripts -- --retry=2. The workspaces are packages/*, packages/channels/* and integrations/external-context*; test:scripts runs scripts/tests/. It does not run integration-tests/.

This PR cannot reach that job

The PR changes exactly two files, integration-tests/test-helper.ts and integration-tests/test-helper.test.ts. integration-tests is not in the root workspaces array, and no scripts/tests/ file reads those two files' contents — no-ak-integration-ci.test.js:174 only asserts that the npm script string lists the filename ./test-helper.test.ts, and integration-vitest-config.test.ts reads integration-tests/vitest.config.js, which is untouched. On this same merge commit, Lint & Static passed and Integration Tests (no-AK, No Sandbox) — the lane that really does execute test-helper.test.ts — also passed.

Reproduction

I ran both of the job's commands on this head. My first attempt was invalid and I discarded it rather than reporting it: this runner hosts a live Qwen session, so the ambient environment had SANDBOX=qwen-code-56cfa215, QWEN_HOME, and OPENAI_API_KEY/OPENAI_BASE_URL/OPENAI_MODEL set, along with the real HOME. That produced 33 failures across packages/cli (config.test.ts, settings.test.ts, Footer.test.tsx, run-qwen-serve-live.test.ts, and the cdCommand/directoryCommand/docsCommand/extensionsCommand/ideCommand tests). packages/cli/src/config/config.ts:2026 reads process.env['SANDBOX'], which is the mechanism. Re-run under a clean CI-shaped environment (env -i, a fresh empty HOME, cleared API keys, no SANDBOX/QWEN_HOME), all 33 pass:

• npm run test:ci:workspaces -- --retry=2 → RC=0. All 22 workspace suites green, including packages/cli 1007 passed (1007), packages/core 636 passed | 1 skipped (637), and packages/web-shell 264 passed (264) — the last being where the merged main content landed.
• npm run test:scripts -- --retry=2 → RC=1, 1 failed | 75 passed (76).

The one failure, and why it is an artifact of my environment

The single failing file is scripts/tests/install-script.test.js, which threw during collection:

Error: `zip`/`unzip` missing on a CI host; archive tests would skip.
 ❯ scripts/tests/install-script.test.js:56:9

That is a deliberate guard at install-script.test.js:52-58: when process.env.CI is set on a non-Windows host and the zip/unzip binaries are missing, it throws so the archive-safety cases cannot silently skip. zip is not installed on this runner (unzip is, tmux and docker are not). CI supplies it in the Install tmux and zip tooling step, which runs before the tests. Re-run without CI=true, the whole suite is green: 76 passed (76), 2117 passed | 16 skipped, with install-script.test.js (126 tests | 16 skipped) passing — the 16 skips being exactly the zip-dependent cases.

So that failure is mine, not the code's, and on its own it does not explain the CI result.

Leading hypothesis for the CI failure — unconfirmed, no log access this round

The same mechanism could plausibly have fired in CI, because the tooling step is advisory by design:

• Install tmux and zip tooling is continue-on-error: true with a 5-minute cap and 140s apt-get bounds (ci.yml:639-677). Its own comments say a stalled mirror or dpkg lock must not "red the required check", and they warn three times that otherwise "the zip-packaging suite will throw on CI".
• Run tests and generate reports (ci.yml:678) gates only on skip_ci and ci_profile; it does not depend on the tooling step's outcome.

An apt-get hiccup on the shared ECS host would therefore let the job reach test:scripts without zip, and install-script.test.js:56 would throw exactly the error above, reddening Test. I reproduced that precise error and that precise path locally. I cannot confirm it happened: this round has no GitHub credentials, so I could not read the job log to see which step failed or whether a ::warning::tmux/zip install failed annotation was emitted. The job's 105-minute wall time against a 110-minute step cap is consistent with the pool contention documented at ci.yml:681-690 and in #10490, but contention alone should not survive --retry=2.

Why I changed nothing for it

Every candidate fix is out of bounds this round. Making the tooling step gating, or making the guard tolerant, means editing .github/workflows/ci.yml (CI machinery this PR was not about) or weakening a deliberate guard in scripts/tests/; either would push the round outside the PR's integration-tests/ footprint. The guard itself is correct as written — if this hypothesis holds, the real problem is that its failure is charged to the wrong check, and that is a maintainer call rather than something to settle inside this PR.

Suggested follow-up: re-run the Test job. If it goes green, this was the tooling step or pool contention. If it fails again on install-script.test.js, then Install tmux and zip tooling is not delivering zip on that pool and the fix belongs in ci.yml or in a prebuilt runner image — not in this PR.

Conflict / base merge

--conflict false, so no merge of origin/main was performed. origin/main has advanced to b4baaf665c since this head's merge base; nothing in this round required it.

Verification

Every command actually run this round, in order:

• npm run build — passed (RC=0)
• Pre-fix mutation probe, QWEN_SANDBOX=false npx vitest run --root ./integration-tests ./test-helper.test.ts --retry=0 — at 8_000: 8 passed; at 3_000: 8 passed (gap reproduced); at 15_000: 8 passed (gap reproduced)
• Post-fix mutation probe, same command — at 3_000: 1 failed | 7 passed (expected 3000 to be greater than 5000); at 1_000: 1 failed | 7 passed; at 15_000: 1 failed | 7 passed (expected 15000 to be less than 10000); integration-tests/test-helper.ts restored byte-identical after each, verified by an empty git diff
• Post-fix baseline, same command at the committed 8_000 — 8 passed (8)
• npm run typecheck — passed (RC=0; includes typecheck:integration, i.e. tsc -p integration-tests/tsconfig.json)
• npm run lint — passed (RC=0; eslint . --ext .ts,.tsx && eslint integration-tests)
• npx prettier --check integration-tests/test-helper.test.ts integration-tests/test-helper.ts — passed
• npm run bundle, then the focused integration file under a clean env — 8 passed (8)
• CI Test-job reproduction, clean env: npm run test:ci:workspaces -- --retry=2 — RC=0, 22 workspace suites green (cli 1007/1007, core 636 passed | 1 skipped, web-shell 264/264)
• CI Test-job reproduction, clean env: npm run test:scripts -- --retry=2 — RC=1, 1 failed file (scripts/tests/install-script.test.js, missing zip with CI=true); re-run without CI=true — 76 passed (76), 2117 passed | 16 skipped
• Pre-commit hooks (lint-staged: prettier --write, eslint --fix --max-warnings 0 --no-warn-ignored) — passed; commit 2e6c42e36a, working tree clean afterwards, no lint-staged stash residue
• npm run generate:settings-schema — not run: no settings source changed
• Integration tests beyond the focused file — not run: integration-tests/test-helper.ts is unchanged this round, so no other integration test's behavior moved

Not available on this runner: the CI job log for Test (ubuntu-latest, Node 22.x) (no GitHub credentials in this round), and the zip, tmux and docker binaries.

Autofix 轮次总结 — PR #11001（issue #10990）

本轮有一条可执行的发现，外加一项失败的检查。该发现已实现并有验证见证；失败的检查在下方给出诊断，且与本 PR 无关。

提交：2e6c42e36a — test(integration): pin the exit grace to literal bounds (#10990)（1 个文件变更，5 行新增）。

已处理的反馈

[rc:3933513088] 与 [rc:3934197269] — R3-1 [Suggestion]：INTERACTIVE_EXIT_GRACE_MS 只由注释钉住 → 已实现

这两条行内评论是同一个发现（第 3 轮及其第 4 轮结转）；一处变更同时解决两者，因此两个线程都列为已解决。

先复现，再改动。 我先针对本轮之前的代码运行了审查者给出的变异探测：

INTERACTIVE_EXIT_GRACE_MS	修复前 test-helper.test.ts 的结果
8_000（已提交的值）	8 passed
3_000 — 低于 CLI 的 5 秒退出清理天花板，即会重新打开 #10990 的那种调整	8 passed（缺口已复现）
15_000 — 高于 vitest 默认的 10 秒 hookTimeout	8 passed（缺口已复现）

这证实了该发现的前提：唯一触及该常量的断言是 expect(cleanupTookMs).toBeLessThan(INTERACTIVE_EXIT_GRACE_MS + 5_000)，它由常量本身推导而来，因此会随它本应监督的值一起被重新调整。

核实了注释所命名的两个边界，而不是直接采信：

• 下限：packages/cli/src/utils/cleanup.ts:36 处的 OVERALL_CLEANUP_TIMEOUT_MS = 5_000。
• 上限：vitest 的解析为 hookTimeout ??= browser.enabled ? 3e4 : 1e4（node_modules/vitest/dist/chunks/coverage.DfSpMS-b.js:3922），而 integration-tests/vitest.config.ts 只设置了 testTimeout 而没有设置 hookTimeout，因此 afterEach 调用方适用的是默认的 10 秒。

变更 — 在 integration-tests/test-helper.test.ts 中新增 5 行，位于本 PR 已经添加的 never-exit 用例内部：两条字面边界断言，外加一条说明它们为何使用字面值而非推导值的注释。未改动任何生产代码；integration-tests/test-helper.ts 与本轮之前的 head 字节级一致。

修复见证 — 变更后重新运行同一探测，每个变异体之后都将 test-helper.ts 恢复为字节级一致（通过空的 git diff 验证）：

INTERACTIVE_EXIT_GRACE_MS	修复后的结果
3_000	1 failed | 7 passed — expected 3000 to be greater than 5000
1_000	1 failed | 7 passed — expected 1000 to be greater than 5000
15_000	1 failed | 7 passed — expected 15000 to be less than 10000
8_000（已恢复）	8 passed

审查者所指的两个方向现在都会让套件变红，且每条新增断言都是各自承重的：去掉下限断言，3_000/1_000 就回到绿色；去掉上限断言，15_000 就回到绿色。

位置说明。 该钉界位于 it.skipIf(usesInstalledCli) 内部，与审查者建议的位置一致。.github/workflows/ 下没有任何地方设置 INTEGRATION_TEST_USE_INSTALLED_GEMINI，因此凡是运行本文件的 CI 通道（包括 no-AK 通道）都会执行这条钉界。把它移出 skipIf 就会开始处理第 4 轮延后的条目「installed-release 通道失去其唯一的 cleanup 见证」，而本轮明确未被要求触及该项。

已记录、本轮未要求 — 未采取行动

两条 review body 都带有标记为「已记录，本轮不要求修改」的 qwen-review-deferred 列表（第 3 轮 1 条，第 4 轮 5 条：逐子进程串行等待宽限、重复的 onExit 包装、InteractiveSession.close() 只发信号不等待、裸的 5_000 上界、installed-release 通道见证，以及 never-exit 替身泄漏）。我全部未动，以把本轮控制在其请求范围之内。增长窗口此前为源码 0/400、测试 0/400 净行；本轮新增测试 5 行、源码 0 行。

失败的检查：Test (ubuntu-latest, Node 22.x) — 已诊断，与本 PR 无关

该 job 实际运行什么

两条命令（ci.yml:756 与 ci.yml:759）：npm run test:ci:workspaces -- --retry=2，然后仅在其通过时运行 npm run test:scripts -- --retry=2。workspaces 为 packages/*、packages/channels/* 与 integrations/external-context*；test:scripts 运行 scripts/tests/。它不运行 integration-tests/。

本 PR 触及不到该 job

本 PR 恰好改动两个文件：integration-tests/test-helper.ts 与 integration-tests/test-helper.test.ts。integration-tests 不在根 workspaces 数组中，且 scripts/tests/ 下没有任何文件读取这两个文件的内容 —— no-ak-integration-ci.test.js:174 只是断言 npm 脚本字符串里列出了文件名 ./test-helper.test.ts，而 integration-vitest-config.test.ts 读取的是未被触及的 integration-tests/vitest.config.js。在同一个 merge commit 上，Lint & Static 通过，真正执行 test-helper.test.ts 的 Integration Tests (no-AK, No Sandbox) 通道也通过。

复现

我在该 head 上运行了该 job 的两条命令。第一次尝试是无效的，我将其丢弃而未上报：本 runner 上正托管着一个活跃的 Qwen 会话，因此环境中带有 SANDBOX=qwen-code-56cfa215、QWEN_HOME，以及 OPENAI_API_KEY/OPENAI_BASE_URL/OPENAI_MODEL，还有真实的 HOME。这在 packages/cli 中产生了 33 个失败（config.test.ts、settings.test.ts、Footer.test.tsx、run-qwen-serve-live.test.ts，以及 cdCommand/directoryCommand/docsCommand/extensionsCommand/ideCommand 测试）。packages/cli/src/config/config.ts:2026 读取 process.env['SANDBOX']，这就是其机制。在一个干净的、贴近 CI 的环境下重新运行（env -i、全新的空 HOME、清空的 API key、无 SANDBOX/QWEN_HOME），这 33 个全部通过：

• npm run test:ci:workspaces -- --retry=2 → RC=0。全部 22 个 workspace 套件绿，包括 packages/cli 1007 passed (1007)、packages/core 636 passed | 1 skipped (637)、以及 packages/web-shell 264 passed (264) —— 最后这个正是合并进来的 main 内容所落之处。
• npm run test:scripts -- --retry=2 → RC=1，1 failed | 75 passed (76)。

这唯一的失败，以及它为何是我环境的产物

唯一失败的文件是 scripts/tests/install-script.test.js，它在收集阶段抛出：

Error: `zip`/`unzip` missing on a CI host; archive tests would skip.
 ❯ scripts/tests/install-script.test.js:56:9

这是 install-script.test.js:52-58 处一个有意设置的守卫：当非 Windows 主机上设置了 process.env.CI 且缺少 zip/unzip 二进制时，它直接抛出，以免归档安全用例被静默跳过。本 runner 上没有安装 zip（unzip 有，tmux 与 docker 没有）。CI 在测试之前的 Install tmux and zip tooling 步骤中提供它。不带 CI=true 重新运行，整个套件全绿：76 passed (76)，2117 passed | 16 skipped，其中 install-script.test.js (126 tests | 16 skipped) 通过 —— 那 16 个跳过恰好就是依赖 zip 的用例。

所以那个失败属于我的环境，而非代码；它本身并不能解释 CI 的结果。

对 CI 失败的主要假设 —— 未确认，本轮无日志访问权限

同一机制在 CI 中也有可能触发，因为该工具安装步骤按设计只是建议性的：

• Install tmux and zip tooling 是 continue-on-error: true，带 5 分钟上限和 140 秒的 apt-get 界限（ci.yml:639-677）。它自己的注释就写明，卡住的镜像源或 dpkg 锁不得「red the required check」，并三次警告否则「the zip-packaging suite will throw on CI」。
• Run tests and generate reports（ci.yml:678）只以 skip_ci 与 ci_profile 为条件；它并不依赖工具安装步骤的结果。

因此共享 ECS 主机上一次 apt-get 抖动，就会让该 job 在没有 zip 的情况下走到 test:scripts，随后 install-script.test.js:56 抛出上面那个完全相同的错误，使 Test 变红。我在本地复现了这个精确的错误和这条精确的路径。我无法确认它确实发生了：本轮没有 GitHub 凭据，因此我无法读取 job 日志来看是哪一步失败，也无法查看是否输出了 ::warning::tmux/zip install failed 注解。该 job 105 分钟的墙钟时间相对于 110 分钟的步骤上限，与 ci.yml:681-690 及 #10490 中记录的资源池争用相符，但仅有争用应当撑不过 --retry=2。

为什么我没有为它做任何改动

本轮所有候选修复都越界。把工具安装步骤改成阻断性的，或让该守卫变得宽容，都意味着修改 .github/workflows/ci.yml（本 PR 并不涉及的 CI 机制），或削弱 scripts/tests/ 中一个有意的守卫；任一种都会把本轮推出本 PR 的 integration-tests/ 足迹之外。该守卫本身按其写法是正确的 —— 如果这个假设成立，真正的问题在于它的失败被记到了错误的检查上，而那是维护者的判断，不该在本 PR 内部自行了结。

建议的后续动作： 重新运行 Test job。如果变绿，说明是工具安装步骤或资源池争用。如果它再次在 install-script.test.js 上失败，那么就是 Install tmux and zip tooling 在该资源池上没有装上 zip，修复应落在 ci.yml 或预构建的 runner 镜像里 —— 而不是本 PR。

冲突 / base 合并

--conflict false，因此未执行 origin/main 的合并。origin/main 自本 head 的 merge base 之后已前进到 b4baaf665c；本轮没有任何工作需要它。

验证

本轮实际运行过的每一条命令，按顺序：

• npm run build — 通过（RC=0）
• 修复前变异探测，QWEN_SANDBOX=false npx vitest run --root ./integration-tests ./test-helper.test.ts --retry=0 — 8_000 时：8 passed；3_000 时：8 passed（缺口已复现）；15_000 时：8 passed（缺口已复现）
• 修复后变异探测，同一命令 — 3_000 时：1 failed | 7 passed（expected 3000 to be greater than 5000）；1_000 时：1 failed | 7 passed；15_000 时：1 failed | 7 passed（expected 15000 to be less than 10000）；每次之后 integration-tests/test-helper.ts 都恢复为字节级一致，通过空的 git diff 验证
• 修复后基线，同一命令、使用已提交的 8_000 — 8 passed (8)
• npm run typecheck — 通过（RC=0；包含 typecheck:integration，即 tsc -p integration-tests/tsconfig.json）
• npm run lint — 通过（RC=0；eslint . --ext .ts,.tsx && eslint integration-tests）
• npx prettier --check integration-tests/test-helper.test.ts integration-tests/test-helper.ts — 通过
• npm run bundle，随后在干净环境下运行聚焦的集成测试文件 — 8 passed (8)
• CI Test job 复现（干净环境）：npm run test:ci:workspaces -- --retry=2 — RC=0，22 个 workspace 套件全绿（cli 1007/1007、core 636 passed | 1 skipped、web-shell 264/264）
• CI Test job 复现（干净环境）：npm run test:scripts -- --retry=2 — RC=1，1 个失败文件（scripts/tests/install-script.test.js，缺少 zip 且 CI=true）；不带 CI=true 重新运行 — 76 passed (76)，2117 passed | 16 skipped
• 提交前钩子（lint-staged：prettier --write、eslint --fix --max-warnings 0 --no-warn-ignored）— 通过；提交 2e6c42e36a，之后工作树干净，无 lint-staged stash 残留
• npm run generate:settings-schema — 未运行：没有设置项源文件变更
• 聚焦文件之外的集成测试 — 未运行：本轮 integration-tests/test-helper.ts 未变更，因此其他集成测试的行为没有移动

本 runner 上不可用的：Test (ubuntu-latest, Node 22.x) 的 CI job 日志（本轮没有 GitHub 凭据），以及 zip、tmux、docker 二进制。

🤖 Addressed the latest review feedback (round 3/10). What changed, and what I pushed back on: · 已处理最新评审反馈（第 3/10 轮）。改动内容与我反驳保留之处如下：

Round 6 address summary — PR #11001 (issue #10990)

Feedback triaged

feedback.md carried no new inline comments and no new issue-level comments, and both automated reviews (rv:5115030149, rv:5116741592) posted 0 findings — each only re-listed Suggestion-level findings already recorded in the round 3/4/5 deferred lists. Nothing there was implemented, declined, or newly deferred, and there were no inline threads to resolve or reply to, so resolved-comments.txt and comment-replies.json are intentionally omitted.

The only actionable content this round was the two failed checks.

1. Test (ubuntu-latest, Node 22.x) — Required, reproduced, fixed

Root cause. scripts/tests/no-ak-integration-ci.test.js pins package.json's test:integration:no-ak:sandbox:none script byte-for-byte. Commit 7f4d27a3ad (#11004, landed on main 2026-09-04 15:59 UTC) added ./cli/_prompt-latency-policy.test.ts to that script but did not update the pin. The Test job runs npm run test:ci:workspaces and then npm run test:scripts, so the stale pin fails the job.

Reproduction evidence.

• npm run test:scripts at the pre-round HEAD failed no-AK integration CI wiring > defines a focused no-AK integration script with exactly one delta: ./cli/_prompt-latency-policy.test.ts present in package.json, absent from the pinned array. A programmatic set-diff of the two lists confirmed it is the only difference (22 entries vs 21, no extras on the pinned side).
• It fails deterministically in isolation with --retry=0, so it is not a flake.
• Base-branch reproduction: git diff origin/main HEAD -- package.json scripts/tests/no-ak-integration-ci.test.js is empty. Both inputs to the assertion are byte-identical on origin/main and at the merge base 419e8d57b2, so the failure is a pure function of main's own content and reproduces on the base branch by construction — it is not charged to this PR's diff.
• The PR's own diff (integration-tests/test-helper.ts, integration-tests/test-helper.test.ts) is not an input to that assertion. The check that does exercise those files, Integration Tests (no-AK, No Sandbox), is SUCCESS, and no workspace package imports anything from integration-tests/.

Fix (1 line). Added './cli/_prompt-latency-policy.test.ts', to the pinned array at its package.json position (between ./qwen-live-m2-steering.test.ts and ./cli/daemon-invocation-context.test.ts).

package.json was deliberately not touched: #11004's addition is intentional (its final sub-commit is literally "test(integration): run prompt latency policy in PR CI"), so the pin was the stale side — and the root manifest's scripts field is command surface a review round may not rewrite.

Mutation probe (A/B). Removing the added line reproduces the failure — observed twice pre-fix, once in the full suite and once isolated with --retry=0. With the line, the file passes 14/14. The pin is its own witness: being byte-exact, it fails on both a missing and a wrong entry.

2. web-shell E2E Smoke (ubuntu-latest, Node 22.x) — not reproducible here, no PR-side cause

• The job's only test steps are npx vitest run --root ./integration-tests ./chat-transcript-document.test.ts --retry=0 and npm run test:e2e:smoke --workspace=packages/web-shell (Playwright, --grep @smoke).
• chat-transcript-document.test.ts imports only node builtins, vitest, playwright, @qwen-code/web-templates, and packages/cli/src/ui/utils/export/* — it never imports test-helper.ts. The smoke leg runs Playwright specs under packages/web-shell/client/e2e. Neither reads either file this PR changes.
• It cannot be reproduced on this runner: no Chromium is installed (~/.cache/ms-playwright absent, PLAYWRIGHT_BROWSERS_PATH unset) and provisioning it is a networked browser download this round is not permitted to run. An exact CI check unavailable on the current runner is not a failed runnable check.
• No code-level hypothesis ties it to this PR, so nothing was changed for it. If it stays red after this round it needs the job log, which is admin-gated from here.

Other local observations while reproducing (classified, not actioned)

All four are in files this PR does not touch, none is deterministic, and CI runs test:scripts with --retry=2.

• scripts/tests/install-script.test.js > does not package audio-capture test artifacts — failed locally before npm run build with ENOENT … packages/audio-capture/dist; packages/{audio-capture,cli,web-shell}/dist were all absent in this checkout. Passes after npm run build. Local build incompleteness, not a CI signal: CI's npm ci runs prepare, which builds and bundles.
• scripts/tests/qwen-autofix-workflow.test.js > behaviorally replays the stale-duplicate revalidation, including the conflict-only transition — Test timed out in 30000ms under full-suite parallelism; passes in isolation in 9.9s. scripts/tests/vitest.config.ts already names this exact file as a shared-pool contention casualty.
• scripts/tests/qwen-fleet-shepherd-workflow.test.js > behaviorally proves a failed jobs read yields unknown busy-state, not an empty busy-set — assertion failure under full-suite parallelism; the whole file passes in isolation with --retry=0.
• scripts/tests/verify-capture.test.js > renders 256-colour and truecolor via the default-grey fallback — failed 2 of 4 local observations and passed the rest, including the post-fix full run. Nondeterministic pixel assertion (sharp/librsvg plus system fonts).

Conflict and merge notes

--conflict false, so origin/main was not merged. No tracked file other than the one-line test pin was changed; the only other write was setting this repository's local user.name/user.email to qwen-code-dev-bot <qwen-code-dev@service.alibaba.com> because the checkout had no commit identity, matching the author of every earlier commit on this branch. origin/main has advanced to 74fe3a659d since this branch's merge base 419e8d57b2; that catch-up is left to the workflow.

Footprint note (deliberate expansion — please review)

This round touches scripts/tests/, outside the PR's own integration-tests/ footprint. It is one line, in ordinary test code (scripts/tests/** is explicitly exempt from the gate's sensitive-area classes), and it is the only place from which this branch can fix the failing required check. Flagged here so the expansion is reviewed deliberately rather than discovered in the advisory.

Verification

• npm run build — passed (exit 0)
• npm run typecheck — passed (exit 0)
• npm run lint — passed (exit 0)
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/no-ak-integration-ci.test.js --retry=0 (touched file) — 14 passed, including defines a focused no-AK integration script
• Same file before the fix, --retry=0 — 1 failed (defines a focused no-AK integration script): the mutation-probe leg
• npm run test:scripts before the fix, two runs — 3 failed / 2122 passed and 4 failed / 2121 passed. The no-AK pin failure and the install-script.test.js failure appear in the fully captured run; the two runs' failure sets differ only in the flakes classified below, which is itself part of that classification
• npm run test:scripts after the fix — 2 failed / 2123 passed; the no-AK pin and install-script.test.js both now pass, and the 2 remaining are the contention flakes above, each verified green in isolation
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/qwen-fleet-shepherd-workflow.test.js --retry=0 — passed (isolation proof)
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/qwen-autofix-workflow.test.js --retry=0 -t 'behaviorally replays the stale-duplicate revalidation' — passed in 9.9s (isolation proof)
• cd integration-tests && QWEN_SANDBOX=false npx vitest run ./test-helper.test.ts --retry=0 (the PR's own files) — 8 passed, run both before and after npm run build
• npm run generate:settings-schema — not run: no settings source changed
• Integration tests after npm run bundle — not run: the change is a scripts-suite expectation, not behavior reachable only through the bundled CLI
• web-shell E2E Smoke — not runnable here (no Chromium, networked download not permitted); see section 2

第 6 轮处理小结 — PR #11001（issue #10990）

已分诊的反馈

feedback.md 中没有新的行内评论，也没有新的 issue 级评论；两条自动审查（rv:5115030149、rv:5116741592）都发布了 0 条发现——各自只是重新列出了已记录在第 3/4/5 轮延后清单中的 Suggestion 级发现。因此本轮没有实现、拒绝或新延后任何审查发现，也没有需要解决或回复的行内讨论串，故有意省略 resolved-comments.txt 与 comment-replies.json。

本轮唯一可执行的内容是两个失败的检查。

1. Test (ubuntu-latest, Node 22.x) — 必修项，已复现，已修复

根因。 scripts/tests/no-ak-integration-ci.test.js 对 package.json 里的 test:integration:no-ak:sandbox:none 脚本做了逐字节固定（pin）。提交 7f4d27a3ad（#11004，于 2026-09-04 15:59 UTC 合入 main）向该脚本加入了 ./cli/_prompt-latency-policy.test.ts，却没有同步更新这个 pin。Test 作业先跑 npm run test:ci:workspaces，再跑 npm run test:scripts，因此这个过期 pin 会让整个作业失败。

复现证据。

• 在本轮开始前的 HEAD 上执行 npm run test:scripts，no-AK integration CI wiring > defines a focused no-AK integration script 失败，且差异只有一处：./cli/_prompt-latency-policy.test.ts 存在于 package.json，却不在被 pin 的数组中。对两份清单做程序化集合比对，确认这是唯一差异（22 项 vs 21 项，pin 侧没有多余项）。
• 该用例在 --retry=0 下单独运行也稳定失败，因此不是 flaky。
• 基线分支复现：git diff origin/main HEAD -- package.json scripts/tests/no-ak-integration-ci.test.js 结果为空。断言的两个输入在 origin/main 和合并基 419e8d57b2 上都是逐字节相同的，所以该失败完全由 main 自身内容决定，按构造即可在基线分支复现——不应记在本 PR 的 diff 上。
• 本 PR 自己的 diff（integration-tests/test-helper.ts、integration-tests/test-helper.test.ts）不是该断言的输入。真正执行这些文件的检查 Integration Tests (no-AK, No Sandbox) 是 SUCCESS，且没有任何 workspace 包从 integration-tests/ 导入内容。

修复（1 行）。 在被 pin 的数组中按其在 package.json 里的位置加入 './cli/_prompt-latency-policy.test.ts',（位于 ./qwen-live-m2-steering.test.ts 与 ./cli/daemon-invocation-context.test.ts 之间）。

刻意没有改动 package.json：#11004 的新增是有意的（其最后一个子提交标题就是 "test(integration): run prompt latency policy in PR CI"），所以过期的一侧是 pin——而且根 manifest 的 scripts 字段属于审查轮次不得改写的命令面。

变异探针（A/B）。 删掉新增的这一行即可复现失败——修复前已观察到两次，一次在完整套件中，一次在 --retry=0 单独运行时。加上这一行后，该文件 14/14 全绿。这个 pin 本身就是见证：由于是逐字节比对，缺一项或错一项都会失败。

2. web-shell E2E Smoke (ubuntu-latest, Node 22.x) — 本地无法复现，且与本 PR 无因果关系

• 该作业仅有的测试步骤是 npx vitest run --root ./integration-tests ./chat-transcript-document.test.ts --retry=0 和 npm run test:e2e:smoke --workspace=packages/web-shell（Playwright，--grep @smoke）。
• chat-transcript-document.test.ts 只导入 node 内置模块、vitest、playwright、@qwen-code/web-templates 以及 packages/cli/src/ui/utils/export/*——它从不导入 test-helper.ts。smoke 部分运行的是 packages/web-shell/client/e2e 下的 Playwright 用例。两者都不会读取本 PR 改动的任一文件。
• 该检查无法在当前 runner 上复现：没有安装 Chromium（~/.cache/ms-playwright 不存在，PLAYWRIGHT_BROWSERS_PATH 未设置），而准备浏览器属于联网下载，本轮不允许执行。当前 runner 上不可用的精确 CI 检查，不算"可运行检查失败"。
• 没有任何代码级假设能把它与本 PR 关联起来，因此没有为它做任何改动。若本轮之后它仍然红，需要该作业的日志，而日志在此处受管理员权限限制。

复现过程中的其他本地观察（已分类，未处理）

以下四项都位于本 PR 未触碰的文件中，都不是确定性失败，且 CI 对 test:scripts 使用 --retry=2。

• scripts/tests/install-script.test.js > does not package audio-capture test artifacts — 在本地 npm run build 之前以 ENOENT … packages/audio-capture/dist 失败；该 checkout 中 packages/{audio-capture,cli,web-shell}/dist 全部缺失。执行 npm run build 后通过。 属于本地构建不完整，不是 CI 信号：CI 的 npm ci 会运行 prepare，其中包含构建与打包。
• scripts/tests/qwen-autofix-workflow.test.js > behaviorally replays the stale-duplicate revalidation, including the conflict-only transition — 在完整套件并行下 Test timed out in 30000ms；单独运行 9.9s 通过。scripts/tests/vitest.config.ts 中已明确把这个文件列为共享资源池竞争导致的受害者。
• scripts/tests/qwen-fleet-shepherd-workflow.test.js > behaviorally proves a failed jobs read yields unknown busy-state, not an empty busy-set — 在完整套件并行下断言失败；整个文件在 --retry=0 下单独运行通过。
• scripts/tests/verify-capture.test.js > renders 256-colour and truecolor via the default-grey fallback — 本地 4 次观察中失败 2 次、通过 2 次，包括修复后的完整运行。属于非确定性像素断言（sharp/librsvg 加系统字体）。

冲突与合并说明

--conflict false，因此没有合并 origin/main。除那一行测试 pin 之外没有改动任何受版本控制的文件；唯一的另一处写入是设置本仓库的局部 user.name/user.email 为 qwen-code-dev-bot <qwen-code-dev@service.alibaba.com>，因为该 checkout 没有提交身份，这与本分支上此前所有提交的作者一致。origin/main 在本分支合并基 419e8d57b2 之后已前进到 74fe3a659d；该追赶工作留给 workflow 处理。

足迹说明（有意的扩张 — 请审阅）

本轮改动了 scripts/tests/，超出本 PR 自身的 integration-tests/ 足迹。改动只有一行，属于普通测试代码（scripts/tests/** 已明确豁免于门禁的敏感区域分类），并且这是本分支能够修复该失败必过检查的唯一位置。在此明确标出，以便该扩张是被有意审阅，而不是在门禁提示中才被发现。

验证

• npm run build — 通过（exit 0）
• npm run typecheck — 通过（exit 0）
• npm run lint — 通过（exit 0）
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/no-ak-integration-ci.test.js --retry=0（被触碰文件）— 14 passed，含 defines a focused no-AK integration script
• 同一文件在修复之前、--retry=0 — 1 failed（defines a focused no-AK integration script）：即变异探针的另一侧
• 修复前 npm run test:scripts，共两次运行 — 3 failed / 2122 passed 与 4 failed / 2121 passed。完整留存日志的那一次包含 no-AK pin 失败与 install-script.test.js 失败；两次运行的失败集合只在下文归类的 flaky 项上不同，这一点本身就是该归类的依据
• 修复后 npm run test:scripts — 2 failed / 2123 passed；no-AK pin 与 install-script.test.js 均已通过，剩余 2 项即上述竞争型 flaky，且各自单独运行已验证为绿
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/qwen-fleet-shepherd-workflow.test.js --retry=0 — 通过（隔离验证）
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/qwen-autofix-workflow.test.js --retry=0 -t 'behaviorally replays the stale-duplicate revalidation' — 9.9s 通过（隔离验证）
• cd integration-tests && QWEN_SANDBOX=false npx vitest run ./test-helper.test.ts --retry=0（本 PR 自身文件）— 8 passed，在 npm run build 前后各运行一次
• npm run generate:settings-schema — 未运行：没有改动任何 settings 源
• npm run bundle 后的集成测试 — 未运行：本次改动是 scripts 套件的期望值，并非只能通过打包后 CLI 才能触达的行为
• web-shell E2E Smoke — 本地无法运行（缺少 Chromium，且不允许联网下载）；见第 2 节

Partially reviewed — gaps disclosed.

6 Suggestion-level finding(s) this review confirmed are already reported on this PR and are not repeated:

• per-session grace in a serial cleanup() loop vs the per-hook 10s hookTimeout — already reported as R1-1 (comment 3931466680) and in round 3's deferred list; re-listed in round 18's already-reported set
• give-up branch warns without escalating past SIGHUP — already reported as R1-4 (comment 3931466703); re-listed in rounds 8-18
• wrapper-topology case bounds cleanup() from below only, so nothing pins that it resolves promptly — already reported as R1-7 (comment 3931466719) and R10-1; re-listed in round 18
• three POSIX-only cases carry no win32 skip against the suite's own convention — already reported in round 8's deferred list (review 5119373431); re-listed in rounds 11 and 13 and as R15-11, D16-3
• give-up case pins only an upper bound, so a shortened effective grace survives all three tests — already reported as R8-4 / D5-1 and as R14-7 (round 12 deferred list, review 5123352373)
• wrapper case has no finally kill, so a failing run orphans the relaunched stand-in — already reported as R8-6 (rounds 4-5 deferred list, comment 5549153747)

Not reviewed: build-and-test — Integration Tests (CLI, No Sandbox) was skipped in CI and its suite did not run locally; it imports the changed harness module, though Agent 7 verified integration-tests/cli/** makes no runInteractive call, so the new wait is a no-op on that suite.

Not explored to full depth (tool budget reached): "agent 6a": could not read node-pty's kill() / destroy() source (no node_modules in this worktree or the parent checkout) to confirm whether it signals the process grou…; "agent 6a": could not read vitest 3.2.4's source to confirm the 10s hookTimeout default — I used the diff's own stated premise plus integration-tests/vitest.config.ts n….

Not reviewed: reverse audit — stopped before round 3 by the review time budget.

Deferred under the convergence posture (round 19, not a blocker) — recorded, not requested in this round:

• integration-tests/test-helper.test.ts:31 — [review] usesInstalledCli is a dead switch: INTEGRATION_TEST_USE_INSTALLED_GEMINI has three read sites repo-wide and no writer, so all three skipIf gates are permanently skipIf(false)

Residual risk: this loop is persistently critical — Criticals stood in the previous round's work-list and stand again this round (1 Critical(s)), the rate of first-time findings is not falling (this round 0, previous 0), and the standing Critical backlog is not shrinking. The severity floor will not converge it. Recommendation: land-with-residual-risk — the exit is a maintainer risk-acceptance decision (merge, carrying the residual risk), not another review round. Residual-risk inventory for that decision (maintainer to complete):

standing Critical	attack surface	attacker-dependency	blast radius
(each standing Critical)	…	…	…

[Critical] R16-1 [certifies-falsely] [new-surface] The PR description still certifies Fixes #10990 at HEAD d1648f81 — in both the English ## Linked Issues mirror and the Chinese ## 关联 Issue mirror — but the archived CI logs of both failed jobs that trailer rests on name a failing in-test-body assertion and contain zero EPIPE and zero unhandled occurrences, so merging as written records a root-cause fix for a failure class neither job exhibited. Issue #10990 names failed jobs 100890051410 and 100890051579 in run 33829764813 at commit b7815a7e1a82; both logs were re-downloaded at this head rather than inherited, and each ends on FAIL interactive/mid-turn-submit-interactive.test.ts > Mid-turn submit > exits on /quit while the response stream is held mid-turn — 100890051410 with Test Files 1 failed | 8 passed | 1 skipped (10), Duration 195.80s, and 100890051579 (which the body attributes to the documented transient shared-host pressure class) dying on the same test with Test Files 1 failed | 23 passed | 1 skipped (25) — with grep -aci EPIPE and grep -aci unhandled both 0 in both. That failure is an assertion inside the test body (submitUntilMidTurn calls rig.waitForText(HELD_MARKER, 30_000), integration-tests/interactive/mid-turn-submit-interactive.test.ts:162-165, reached from the it at :205 via :209), so it fires before the afterEach at :83-90; the only wait this diff adds lives in TestRig.cleanup(), which vitest runs after the failure is already recorded, so no step of the incident replay changes its outcome after this change. The per-commit filing came from the detector's own documented missing-log fallback (.github/workflows/main-ci-failure-issue.yml:92-94, a file this diff does not touch), and the real repair 56f75adf29 (PR #10986) is already an ancestor of this HEAD. A maintainer closed #10990 on 2026-09-05 as a superseded per-commit E2E alert, so merging attaches a root-cause fix to an alert closed as not actionable while the two real owners — the recurring OpenTUI mid-turn signature and the detector's log-fetch fallback — both ship untouched, and the certification travels into the merge commit message. To be explicit about what this does not say: the teardown wait itself is sound and was measured working again this round — npm run typecheck:integration and eslint on both changed files exit 0, the changed suite is 9/9 green across four consecutive runs with stable timings, and neutering the process-group gate reddens this PR's own bin-wrapper case with expected 201 to be greater than or equal to 750, which is what closes the earlier Critical about the installed-release lane. Nothing needs reverting except the attribution. Keep the wait as teardown hygiene, which the orphan measurement already in the description justifies on its own, and drop Fixes #10990 from BOTH body mirrors (removing one leaves the claim standing), correcting the Why it's needed premise and the second-job paragraph to what the two logs show. If a tracker is wanted, point it at the recurring OpenTUI mid-turn signature or at the detector's log-fetch fallback, not at a per-commit alert a maintainer closed as superseded. There is no test to add for an attribution change, and that absence is itself corroborating: all three cases this diff adds stay green whether or not the OpenTUI leg's real failure is addressed. This edit needs a human — the author's own round-9 handoff (comment 5575809982) records that the AutoFix loop cannot perform it, having no GitHub credentials and no PR-body update path in qwen-autofix.yml in any mode — and this is the fourth consecutive round in which it has been the only standing blocker. Witness, re-measured at this head rather than inherited: gh pr view 11001 --json headRefOid returns d1648f8143a46c3211864dbf4eae802d43af375a, and grepping that body for 10990 returns line 60 ## Linked Issues / line 62 Fixes #10990 and line 126 ## 关联 Issue / line 128 Fixes #10990; job 100890051410 (774458 B) carries the FAIL line with AssertionError: Held response never reached the screen, so the turn is not mid-stream: expected false to be true then ##[error]Process completed with exit code 1. and EPIPE 0 / unhandled 0; job 100890051579 (9631985 B) carries the same FAIL with EPIPE 0 / unhandled 0; gh issue view 10990 --json state,closedAt gives CLOSED / 2026-09-05T04:38:27Z with the collaborator's note that a recurring signature should be tracked in one canonical test issue rather than one issue per commit; git merge-base --is-ancestor 56f75adf29 HEAD exits 0; and git grep -n 10990 HEAD -- integration-tests returns no hits. A fix must not re-introduce a #10990 reference into the code comment: integration-tests/test-helper.ts:566 at HEAD reads // writes EPIPE and fail an otherwise all-green run (#10969). Signalling, and both code-side (#10990) attributions were already correctly dropped in 4e37d2e4a4.

Partially reviewed — gaps disclosed.

2 Suggestion-level finding(s) this review confirmed are already reported on this PR and are not repeated:

• S20-1 the give-up branch warns without escalating past SIGHUP (integration-tests/test-helper.ts:580) — already reported as R1-4 (comment 3931466703); re-listed in rounds 8-19
• S20-2 the immortal stand-in is reaped by a finally wrapping only rig.cleanup() (integration-tests/test-helper.test.ts:197) — already reported in round 4's deferred list (review 5113219708); re-listed as R5-1, R8-6, R14-6, round 13 and D16-7

Not reviewed: build-and-test — Integration Tests (CLI, No Sandbox) was skipped in CI; locally the changed file's own suite ran 9/9 green, one no-AK consumer suite 2/2 green, and typecheck:integration plus eslint clean, but the rest of that job's no-AK integration domain (the other interactive/, cli/, sdk-typescript/ and qwen-live-* suites) did not run.

Not explored to full depth (tool budget reached): "agent 6c": I could not read node-pty's own kill() / _close() implementation (no node_modules in this worktree or in the parent checkout), so the SIGHUP-default, master….

Deferred under the convergence posture (round 20, not a blocker) — recorded, not requested in this round:

• (body) — [probe] D20-1 the Risk & Scope bullet charges hook time to the 5-minute testTimeout instead of vitest's separate 10s hookTimeout, which integration-tests/vitest.config.ts never raises — 28 of 35 rig.cleanup() call sites sit inside …

Residual risk: this loop is persistently critical — Criticals stood in the previous round's work-list and stand again this round (1 Critical(s)), the rate of first-time findings is not falling (this round 0, previous 0), and the standing Critical backlog is not shrinking. The severity floor will not converge it. Recommendation: land-with-residual-risk — the exit is a maintainer risk-acceptance decision (merge, carrying the residual risk), not another review round. Residual-risk inventory for that decision (maintainer to complete):

standing Critical	attack surface	attacker-dependency	blast radius
(each standing Critical)	…	…	…

Advisory only — it does not block this review.

[Critical] R16-1: [certifies-falsely] [new-surface] The PR description still certifies Fixes #10990 at HEAD 69878a28 — in both the English ## Linked Issues mirror (body line 62) and the Chinese ## 关联 Issue mirror (body line 128) — but the archived CI logs of both failed jobs that trailer rests on name a failing in-test-body assertion and contain zero EPIPE and zero unhandled occurrences, so merging as written records a root-cause fix for a failure class neither job exhibited. Issue #10990 names failed jobs 100890051410 and 100890051579 in run 33829764813 at commit b7815a7e1a82; both logs were re-downloaded at this head rather than inherited, and each ends on FAIL interactive/mid-turn-submit-interactive.test.ts > Mid-turn submit > exits on /quit while the response stream is held mid-turn — 100890051410 with Test Files 1 failed | 8 passed | 1 skipped (10), and 100890051579 (which the body attributes to the documented transient shared-host pressure class) dying on the same test with Test Files 1 failed | 23 passed | 1 skipped (25), so that paragraph is falsified too — with grep -ci EPIPE and grep -ci unhandled both 0 in both. That failure is an assertion inside the test body (submitUntilMidTurn calls rig.waitForText(HELD_MARKER, 30_000), integration-tests/interactive/mid-turn-submit-interactive.test.ts:154-165, reached from the it at :208), so it fires before the afterEach at :83-91; the only wait this diff adds lives in TestRig.cleanup(), which vitest runs after the failure is already recorded, so no step of the incident replay changes its outcome after this change. The body's premise — that the leg "keeps reddening main without naming a single failing test" and that "a run that passes everything and still exits non-zero is an unhandled error" — is therefore false for the very run the trailer cites: the log carries a named failing test, and the detector named none because its own log downloads failed, the documented missing-log fallback at .github/workflows/main-ci-failure-issue.yml:92-94, a file this diff does not touch. The real repair 56f75adf29 (PR #10986) is already an ancestor of this HEAD. A maintainer closed #10990 on 2026-09-05 as a superseded per-commit E2E alert, so merging attaches a root-cause fix to an alert closed as not actionable while the two real owners — the recurring OpenTUI mid-turn signature and the detector's log-fetch fallback — both ship untouched, and the certification travels into the merge commit message. This is the still-standing residual of the thread at comment 3941788037, not a new claim: its two CODE attributions were correctly dropped in 4e37d2e4a4 (integration-tests/test-helper.ts:566 now cites (#10969), and git grep -n 10990 HEAD -- integration-tests returns no hits), the body trailer was not, and the author's own round-9 handoff (comment 5575809982) records that the AutoFix loop cannot perform a PR-body edit — it has no GitHub credentials and qwen-autofix.yml exposes no body-update path in any mode — so this one needs a maintainer, and this is the fifth consecutive round in which it has been the only standing blocker. To be explicit about what this does not say: the teardown wait itself is sound and was measured working again this round — npm run typecheck:integration and eslint on both changed files exit 0, the changed suite is 9/9 green with the three new cases at 959ms, 1003ms and 8216ms, a real consumer suite is 2/2 green, and zeroing the grace (Date.now() + ms * 0) KILLS 2 tests with cleanup() returned before the interactive CLI child exited: expected 51 to be greater than or equal to 750. Nothing needs reverting except the attribution. Keep the wait as teardown hygiene, which the orphan measurement already in the description justifies on its own, and drop Fixes #10990 from BOTH body mirrors (removing one leaves the claim standing), correcting the Why it's needed premise and the second-job paragraph to what the two logs show. If a tracker is wanted, point it at the recurring OpenTUI mid-turn signature or at the detector's log-fetch fallback, not at a per-commit alert a maintainer closed as superseded. There is no test to add for an attribution change, and that absence is itself corroborating: all three cases this diff adds stay green whether or not the OpenTUI leg's real failure is addressed. Witness, re-measured at this head rather than inherited: gh pr view 11001 --json headRefOid returns 69878a286231fe5002d8cf3d43bd0f8fbc846d21 with Fixes #10990 at body lines 62 and 128; job 100890051410 (774458 B) carries the FAIL line with AssertionError: Held response never reached the screen, so the turn is not mid-stream: expected false to be true then ##[error]Process completed with exit code 1. and EPIPE 0 / unhandled 0; job 100890051579 carries the same FAIL with ##[error]sandbox:none shard failed on ecs-qwen-hk4-28 after 2334s of the 3600s job budget and EPIPE 0 / unhandled 0; detector job 100899524656 reads Could not download the log of job 100890051410, Could not download the log of job 100890051579, then Failing tests identified: 0; gh api repos/QwenLM/qwen-code/issues/10990 gives state: closed, state_reason: completed, closed_at: 2026-09-05T04:38:27Z with the collaborator's note that "A recurring signature should be tracked in one canonical test issue rather than one issue per commit"; and git merge-base --is-ancestor 56f75adf29 HEAD exits 0. Two existing facts the fix must not violate: do not revert the wait to drop the attribution, because integration-tests/test-helper.test.ts case waits for the CLI the installed bin wrapper relaunched to end asserts expect(Date.now() - cleanupStartedAt).toBeGreaterThanOrEqual(STAND_IN_EXIT_DELAY_MS) and expect(isProcessAlive(relaunchedPid)).toBe(false) — removing the process-group gate reds it and reopens the closed Critical R9-8; and integration-tests/test-helper.ts:566 reads // writes EPIPE and fail an otherwise all-green run (#10969). Signalling at HEAD, where #10969 is a real closed alert whose EPIPE mechanism PR #10971 addressed, so that citation is correct as it stands and must NOT be changed back to #10990. No test can pin this fix, and that is the acceptance criterion: a PR-description trailer edit adds no guard, branch or behaviour, so all three cases this diff adds must stay green whether or not the OpenTUI leg's real failure is addressed.

[Critical] R16-1: [certifies-falsely] [new-surface] The PR description still certifies Fixes #10990 at HEAD 69878a28 — in both the English ## Linked Issues mirror (body line 62) and the Chinese ## 关联 Issue mirror (body line 128) — but the archived CI logs of both failed jobs that trailer rests on name a failing in-test-body assertion and contain zero EPIPE and zero unhandled occurrences, so merging as written records a root-cause fix for a failure class neither job exhibited. Issue #10990 names failed jobs 100890051410 and 100890051579 in run 33829764813 at commit b7815a7e1a82; both logs were re-downloaded at this head rather than inherited, and each ends on FAIL interactive/mid-turn-submit-interactive.test.ts > Mid-turn submit > exits on /quit while the response stream is held mid-turn — 100890051410 with Test Files 1 failed | 8 passed | 1 skipped (10), and 100890051579 (which the body attributes to the documented transient shared-host pressure class) dying on the same test with Test Files 1 failed | 23 passed | 1 skipped (25), so that paragraph is falsified too — with grep -ci EPIPE and grep -ci unhandled both 0 in both. That failure is an assertion inside the test body (submitUntilMidTurn calls rig.waitForText(HELD_MARKER, 30_000), integration-tests/interactive/mid-turn-submit-interactive.test.ts:154-165, reached from the it at :208), so it fires before the afterEach at :83-91; the only wait this diff adds lives in TestRig.cleanup(), which vitest runs after the failure is already recorded, so no step of the incident replay changes its outcome after this change. The body's premise — that the leg "keeps reddening main without naming a single failing test" and that "a run that passes everything and still exits non-zero is an unhandled error" — is therefore false for the very run the trailer cites: the log carries a named failing test, and the detector named none because its own log downloads failed, the documented missing-log fallback at .github/workflows/main-ci-failure-issue.yml:92-94, a file this diff does not touch. The real repair 56f75adf29 (PR #10986) is already an ancestor of this HEAD. A maintainer closed #10990 on 2026-09-05 as a superseded per-commit E2E alert, so merging attaches a root-cause fix to an alert closed as not actionable while the two real owners — the recurring OpenTUI mid-turn signature and the detector's log-fetch fallback — both ship untouched, and the certification travels into the merge commit message. This is the still-standing residual of the thread at comment 3941788037, not a new claim: its two CODE attributions were correctly dropped in 4e37d2e4a4 (integration-tests/test-helper.ts:566 now cites (#10969), and git grep -n 10990 HEAD -- integration-tests returns no hits), the body trailer was not, and the author's own round-9 handoff (comment 5575809982) records that the AutoFix loop cannot perform a PR-body edit — it has no GitHub credentials and qwen-autofix.yml exposes no body-update path in any mode — so this one needs a maintainer, and this is the fifth consecutive round in which it has been the only standing blocker. To be explicit about what this does not say: the teardown wait itself is sound and was measured working again this round — npm run typecheck:integration and eslint on both changed files exit 0, the changed suite is 9/9 green with the three new cases at 959ms, 1003ms and 8216ms, a real consumer suite is 2/2 green, and zeroing the grace (Date.now() + ms * 0) KILLS 2 tests with cleanup() returned before the interactive CLI child exited: expected 51 to be greater than or equal to 750. Nothing needs reverting except the attribution. Keep the wait as teardown hygiene, which the orphan measurement already in the description justifies on its own, and drop Fixes #10990 from BOTH body mirrors (removing one leaves the claim standing), correcting the Why it's needed premise and the second-job paragraph to what the two logs show. If a tracker is wanted, point it at the recurring OpenTUI mid-turn signature or at the detector's log-fetch fallback, not at a per-commit alert a maintainer closed as superseded. There is no test to add for an attribution change, and that absence is itself corroborating: all three cases this diff adds stay green whether or not the OpenTUI leg's real failure is addressed.

Two existing facts the fix must not violate: do not revert the wait to drop the attribution, because integration-tests/test-helper.test.ts case waits for the CLI the installed bin wrapper relaunched to end asserts expect(Date.now() - cleanupStartedAt).toBeGreaterThanOrEqual(STAND_IN_EXIT_DELAY_MS) and expect(isProcessAlive(relaunchedPid)).toBe(false) — removing the process-group gate reds it and reopens the closed Critical R9-8; and integration-tests/test-helper.ts:566 reads // writes EPIPE and fail an otherwise all-green run (#10969). Signalling at HEAD, where #10969 is a real closed alert whose EPIPE mechanism PR #10971 addressed, so that citation is correct as it stands and must NOT be changed back to #10990. No test can pin this fix, and that is the acceptance criterion: a PR-description trailer edit adds no guard, branch or behaviour, so all three cases this diff adds must stay green whether or not the OpenTUI leg's real failure is addressed.

Partially reviewed — gaps disclosed.

2 Suggestion-level finding(s) this review confirmed are already reported on this PR and are not repeated:

• R21-4 wrapper-topology case bounds cleanup() from below only, so nothing pins that it resolves promptly once the session is gone (integration-tests/test-helper.test.ts:171) — already reported as R10-1 in round 10's deferred list (review 512…
• R21-7 wrapper case has no finally teardown, so an assertion failing before rig.cleanup() orphans both stand-ins (integration-tests/test-helper.test.ts:158) — already reported in round 4's deferred list (review 5113219708); re-listed as R5-1…

Not reviewed: build-and-test — Integration Tests (CLI, No Sandbox) was skipped in CI, and both changed files sit outside every npm workspace so build-test scoped them out: no build or test command executed for them in this review. The no-AK leg that does list ./test-helper.test.ts (ci.yml:1825 integration_no_ak -> package.json:61) was verified by reading config, not by running it; test-efficacy reported harnessValidated: null with probed: [] and every mutant/hunk counter 0, so the probe harness neither validated nor refuted coverage.

Residual risk: this loop is persistently critical — Criticals stood in the previous round's work-list and stand again this round (1 Critical(s)), the rate of first-time findings is not falling (this round 0, previous 0), and the standing Critical backlog is not shrinking. The severity floor will not converge it. Recommendation: land-with-residual-risk — the exit is a maintainer risk-acceptance decision (merge, carrying the residual risk), not another review round. Residual-risk inventory for that decision (maintainer to complete):

standing Critical	attack surface	attacker-dependency	blast radius
(each standing Critical)	…	…	…

Advisory only — it does not block this review.

[Critical] R16-1: [certifies-falsely] [new-surface] The PR description still certifies Fixes #10990 at HEAD 2a5e7290 — in BOTH the English ## Linked Issues mirror (body line 62) and the Chinese ## 关联 Issue mirror (body line 128) — but the archived CI logs of both failed jobs that trailer rests on name a failing in-test-body assertion and contain zero EPIPE and zero unhandled occurrences, so merging as written records a root-cause fix for a failure class neither job exhibited, and the certification travels into the squash-merge commit body. Issue #10990 names failed jobs 100890051410 (E2E Interactive - OpenTUI renderer (bun)) and 100890051579 (E2E Test (Linux) - sandbox:none - shard 2/3) of run 33829764813 at commit b7815a7e1a82; both logs were re-downloaded at this head rather than inherited, and each ends on FAIL interactive/mid-turn-submit-interactive.test.ts > Mid-turn submit > exits on /quit while the response stream is held mid-turn — 100890051410 with AssertionError: Held response never reached the screen, so the turn is not mid-stream: expected false to be true and Test Files 1 failed | 8 passed | 1 skipped (10), 100890051579 (which the body attributes to the documented transient shared-host pressure class) dying on the same test with 1 failed | 23 passed | 1 skipped (25), so that paragraph is falsified too — with grep -aci EPIPE and grep -aci unhandled both 0 in both. The log's own stack puts the failure in the it body (expectExitMidTurn at :199:71, reached from :213:5), while await rig.cleanup() lives only in the afterEach at :82-90, which vitest runs AFTER the body failure is recorded; the only wait this diff adds is inside TestRig.cleanup() (integration-tests/test-helper.ts:563-586), so no step of the incident replay changes its outcome after this change. The body's premise — that the leg "keeps reddening main without naming a single failing test" and that "a run that passes everything and still exits non-zero is an unhandled error" — is therefore false for the very run the trailer cites: the log carries a named failing test, and the detector named none because its own log downloads failed, the documented missing-log fallback at .github/workflows/main-ci-failure-issue.yml:90-97, a file this diff does not touch. The real repair 56f75adf29 (PR #10986) is already an ancestor of this HEAD. A maintainer closed #10990 on 2026-09-05 as "a superseded per-commit E2E alert … no longer actionable", so merging attaches a root-cause fix to an alert closed as not actionable while the two real owners — the recurring OpenTUI mid-turn signature and the detector's log-fetch fallback — both ship untouched. The trailer does travel into history: landed squash commit d670d47e on main carries its PR description prose plus its Fixes #11253 trailer in the commit body. This is the still-standing residual of the thread at comment 3941788037, not a new claim: its two CODE attributions were correctly dropped in 4e37d2e4a4 (integration-tests/test-helper.ts:566 now cites (#10969), and git grep -n 10990 HEAD -- integration-tests returns no hits), the body trailer was not, and the author's own round-9 handoff (comment 5575809982) records that the AutoFix loop cannot perform a PR-body edit — it has no GitHub credentials and qwen-autofix.yml exposes no body-update path in any mode — so this one needs a maintainer, and this is the sixth consecutive round in which it has been the only standing blocker. To be explicit about what this does not say: the teardown wait itself is sound and nothing needs reverting except the attribution. Keep the wait as teardown hygiene, which the orphan measurement already in the description justifies on its own, and drop Fixes #10990 from BOTH body mirrors (removing one leaves the claim standing), correcting the Why it's needed premise and the second-job paragraph to what the two logs show, and keeping the trailer out of the final merge message. If a tracker is wanted, point it at the recurring OpenTUI mid-turn signature or at the detector's log-fetch fallback, not at a per-commit alert a maintainer closed as superseded. There is no test to add for an attribution change, and that absence is itself corroborating: all three cases this diff adds stay green whether or not the OpenTUI leg's real failure is addressed. Witness, re-measured at this head rather than inherited: gh pr view 11001 --json headRefOid returns 2a5e7290b2eb462556a211266885a0088a76ec4b with Fixes #10990 at body lines 62 and 128; job 100890051410 (774458 B) carries the FAIL line then ##[error]Process completed with exit code 1. and EPIPE 0 / unhandled 0; job 100890051579 (9631985 B) carries the same FAIL with EPIPE 0 / unhandled 0; git merge-base --is-ancestor 56f75adf29 HEAD exits 0; gh api repos/QwenLM/qwen-code/issues/10990 gives state: closed, state_reason: completed, closed_at: 2026-09-05T04:38:27Z; and the landed squash d670d47e body contains Fixes #11253. Two existing facts the fix must not violate: integration-tests/test-helper.ts:566 reads // writes EPIPE and fail an otherwise all-green run (#10969).

🤖 AutoFix updated a stale base — the fix did not pass verification, but this PR was behind main, so it merged current main in via update-branch and will retry on the next scan. A stale base (a dependency or symbol main already changed) can fail the build without being the fix's fault; if it still fails once current, it hands off to a human.

What I found before stopping:

AutoFix stopped: the only standing finding requires a maintainer's PR-body edit

Outcome: no code change; deliberate escalation to a maintainer. The single standing blocker on this PR — Critical R16-1, re-reported in review rounds 17-22 and re-measured at the current head a6a77c98 — is not in the code. It is the PR description, which still certifies Fixes #10990 in both the English ## Linked Issues section (body line 62) and the Chinese ## 关联 Issue section (body line 128). This loop cannot edit a PR body: the agent has no GitHub credentials (gh is unauthenticated in this environment), and qwen-autofix.yml exposes no body-update path in any mode (verified: gh pr edit appears nowhere in the workflow; --body-file is used only at PR creation in the develop-issue lane). A maintainer must make this edit; the loop cannot converge without it.

What the maintainer needs to do

Per the standing review finding:

1. Drop Fixes #10990 from BOTH body mirrors — removing only one leaves the close-on-merge claim standing.
2. Correct the "Why it's needed" premise and the second-job paragraph to what the two archived job logs actually show: jobs 100890051410 and 100890051579 both failed the named in-test-body assertion interactive/mid-turn-submit-interactive.test.ts > Mid-turn submit > exits on /quit while the response stream is held mid-turn, with zero EPIPE and zero unhandled occurrences in either log. The per-commit issue came from the detector'

停止前我了解到的情况：

AutoFix 停止：唯一未决发现需要维护者编辑 PR 描述

结果：不改代码；有意升级给维护者。 本 PR 上唯一未决的阻断项 —— Critical R16-1,在第 17-22 轮评审中反复报告，并在当前 head a6a77c98 上重新测量 —— 不在代码里。它在 PR 描述中：英文 ## Linked Issues 小节(正文第 62 行)和中文 ## 关联 Issue 小节(正文第 128 行)仍写着 Fixes #10990。本循环无法编辑 PR 描述：agent 没有 GitHub 凭据(此环境中 gh 未认证),且 qwen-autofix.yml 在任何模式下都没有正文更新路径(已核实：gh pr edit 在整个工作流中不存在；--body-file 仅在 develop-issue 通道创建 PR 时使用)。这项编辑必须由维护者完成；没有它，循环无法收敛。

维护者需要做什么

按这条未决评审发现的要求：

1. 从两个正文镜像中都删掉 Fixes #10990 —— 只删一个，合并即关闭的声明仍然成立。
2. 把 "Why it's needed" 的前提和第二段的作业描述改成两个归档作业日志实际显示的内容：作业 100890051410 和 100890051579 都是在具名的测试体内断言 interactive/mid-turn-submit-interactive.test.ts > Mid-turn submit > exits on /quit while the response stream is held mid-turn 上失败的，两份日志中 EPIPE 和 unhandled 出现次数均为零。这个按提交提交的 issue 来自检测器有文档记录的日志缺失回退(.github/workflows/main-ci-failure-issue.yml:92-94),而不是 EPIPE 故障类别。
3. 注意真正的修复 56f75adf29(PR fix(cli): resolve the OpenTUI slash submit from the live buffer on Enter #10986)已经是当前 head 的祖先；Main CI failed: E2E Tests on b7815a7e1a82 #10990 已由维护者于 2026-09-05 作为被取代的按提交 E2E 告警关闭。如果需要追踪单，请指向反复出现的 OpenTUI mid-turn 特征或检测器的日志抓取回退，而不是那个已关闭的按提交告警。

评审者自己的建议是 land-with-residual-risk:出口是维护者的风险接受决定(在更正署名后合并),而不是再来一轮评审。这已经是 R16-1 连续第七轮成为唯一未决阻断项。

代码保持现状

本 PR 添加的 teardown 等待已验证是可靠的；无需回退任何东西。评审给出的约束：integration-tests/test-helper.ts:566 的 (#10969) 引用保持原样是正确的，绝不可改回 #10990;.github/scripts/ci/main-failure-signature.mjs 未被本 diff 触及，必须保持不动；不要为了去掉署名而回退 cleanup 等待。署名类修改没有需要新增的测试。

本轮检查了什么

• HEAD 是 a6a77c98e18ca5742d438ff0af4205db6a6b3813,与第 22 轮评审账本中的 SHA 一致，因此该发现的测量是当前的。
• git grep -n 10990 HEAD -- integration-tests 无命中：代码中不携带 #10990 署名。
• git merge-base --is-ancestor 56f75adf29 HEAD 退出码为 0：真正的修复已在历史中。
• integration-tests/test-helper.ts:566 为 `// writes EPIPE and fail an otherwise all-green run (Main CI failed: E2E Tests on f6a7eee341b0 #10969). Signalli

Partially reviewed — gaps disclosed.

4 Suggestion-level finding(s) this review confirmed are already reported on this PR and are not repeated:

• R23-2 give-up branch warns without ending the surviving PTY writer — already reported as R1-4 (comment 3931466703)
• R23-3 installed-release lane loses its only cleanup witness — already reported as R1-6 (comment 3931466715)
• R23-5 sessionEndsWithin bypasses the file's own TestRig.poll wait helper — already reported as R1-2 (comment 3931466693) and in round 11's deferred list (review 5122696531)
• R23-6 pre-cleanup assertion failure leaks the stand-in, and test 3's SIGHUP-ignoring stand-in is immortal — already recorded as D22-1 in round 22's deferred list (review 5149582150)

Not reviewed: build-and-test — Integration Tests (CLI, No Sandbox) was skipped in CI and its credential-bearing suite did not run locally.

Not reviewed: reverse audit — stopped before round 3 by the review time budget.

Residual risk: this loop is persistently critical — Criticals stood in the previous round's work-list and stand again this round (1 Critical(s)), the rate of first-time findings is not falling (this round 0, previous 0), and the standing Critical backlog is not shrinking. The severity floor will not converge it. Recommendation: land-with-residual-risk — the exit is a maintainer risk-acceptance decision (merge, carrying the residual risk), not another review round. Residual-risk inventory for that decision (maintainer to complete):

standing Critical	attack surface	attacker-dependency	blast radius
(each standing Critical)	…	…	…

Advisory only — it does not block this review.

[Critical] R16-1: [certifies-falsely] [new-surface] The PR description still certifies Fixes #10990 at HEAD edaf7e12 in both the English ## Linked Issues mirror and the Chinese ## 关联 Issue mirror, but a sweep of GitHub's own archived job logs over the six failed E2E Interactive - OpenTUI renderer (bun) legs in the window the body cites finds 6 of 6 naming a failing in-test-body assertion and 0 of 6 containing EPIPE, unhandled, unhandledRejection, uncaughtException, ERR_STREAM or write after end, so merging as written records a root-cause fix for a failure class none of those runs exhibited. Issue #10990's two named jobs are 100890051410 and 100890051579 in run 33829764813 at commit b7815a7e1a82; both end on FAIL interactive/mid-turn-submit-interactive.test.ts > Mid-turn submit > exits on /quit while the response stream is held mid-turn, with AssertionError: Held response never reached the screen, so the turn is not mid-stream: expected false to be true and Test Files 1 failed | 8 passed | 1 skipped (10) in the first, and AssertionError: /quit did not exit while the stream was held: expected null to deeply equal ObjectContaining { and Test Files 1 failed | 23 passed | 1 skipped (25) in the second. Those are assertions inside the test body, so they fire before the afterEach, and the only wait this diff adds lives in TestRig.cleanup(), which vitest runs after the failure is already recorded — no step of the incident replay changes its outcome after this change. The per-commit filing came from the detector's own documented missing-log fallback (.github/workflows/main-ci-failure-issue.yml:89-96), a file this diff does not touch. A maintainer closed issue 10990 on 2026-09-05 as a superseded per-commit E2E alert, and issue 10994, which the body's second-job paragraph points at, is closed too, so merging attaches a root-cause fix to an alert closed as not actionable while the two real owners — the recurring OpenTUI mid-turn byte-stream signature and the detector's log-fetch fallback — both ship untouched with nothing tracking them, and the certification travels into the squash-merge commit body (git log bae90d7afa..HEAD carries zero closing trailers, so the claim exists only in the description). To be explicit about what this does not say: the teardown wait itself is sound and was measured working again this round — npm ci exit 0, npm run typecheck:integration exit 0, the changed suite 9/9 green, and the whole no-AK integration gate 24 files / 190 tests green — and neutering the process-group gate reddens this PR's own bin-wrapper case with expected 201 to be greater than or equal to 750. Nothing needs reverting except the attribution. Drop Fixes #10990 from BOTH body mirrors (removing one leaves the claim standing), keep the trailer out of the merge message, and restate the Why it's needed premise to what the logs show. Two further body claims must not survive the rewrite: the ## Risk & Scope out-of-scope bullet says the one interactive file with its own launcher copy "never applies the renderer overlay", but integration-tests/interactive/external-context-mem0-write.test.ts:492 calls resolveE2eCliCommand(renderer) and :501 spreads ...e2eRendererEnv(renderer), identically at the merge base; and although 56f75adf29 (PR 10986) is confirmed an ancestor of this HEAD, the OpenTUI leg of that very commit — run 33834473606, job 100909628476 — still reddened on the same signature, the first green leg in the window being run 33843599960 at a6dcae2ce52d, so a corrected body must not date the recovery one commit too early. Nor should the second-job paragraph be deleted wholesale: that log does corroborate the retry-starvation half (sandbox:none shard failed on ecs-qwen-hk4-28 after 2334s of the 3600s job budget), so it is incomplete rather than invented. There is no test to add for an attribution change, and that absence is itself corroborating — all three cases this diff adds stay green whether or not the OpenTUI leg's real failure is addressed. This edit needs a human: the author's own round-9 handoff records that the AutoFix loop has no GitHub credentials and that qwen-autofix.yml exposes no PR-body update path in any mode, and the loop has since paused at its 10/10 round cap. This is the eighth consecutive round in which this has been the only standing blocker, and the review's own recommendation stays land-with-residual-risk — the exit is a maintainer risk-acceptance decision (correct the attribution, then merge), not another review round. Fix constraint: integration-tests/test-helper.ts:566 reads (#10969) at HEAD and is correct — it must NOT be changed to #10990 or removed as part of this edit; do not drop the wait to drop the attribution, because test-helper.ts:172 const gone = childExited && !sessionAlive(pid); is what the new case waits for the CLI the installed bin wrapper relaunched to end pins; and .github/scripts/ci/main-failure-signature.mjs is untouched by this diff and must stay so. Fix witness: N/A — a PR-body attribution edit adds no guard, branch or behaviour a test can pin.

Fix constraint: integration-tests/test-helper.ts:566 reads (#10969) at HEAD and is correct — it must NOT be changed to #10990 or removed as part of this edit; do not drop the wait to drop the attribution, because test-helper.ts:172 const gone = childExited && !sessionAlive(pid); is what the new case waits for the CLI the installed bin wrapper relaunched to end pins, and removing the process-group gate reddens it with expected 0 to be greater than or equal to 750; and .github/scripts/ci/main-failure-signature.mjs is untouched by this diff and must stay so, because its VITEST_FAIL_PATTERN at :41 does match the space-prefixed vitest FAIL line once cleanLine() at :49-55 strips ANSI, a leading timestamp and collapsed whitespace.

Partially reviewed — gaps disclosed.

1 Suggestion-level finding(s) this review confirmed are already reported on this PR and are not repeated:

• F14 Pre-cleanup assertion failure leaks the SIGHUP-immune… at integration-tests/test-helper.test.ts:197 — already reported (D22-1 round 22 review 5149582150; R23-6; D24-3 round 24 review 5170256404)

Not reviewed: build-and-test — "Integration Tests (CLI, No Sandbox)" was skipped in CI at this commit; locally the changed suite and its no-AK-reachable consumers ran green (test-helper.test.ts 11 passed with all three new cases executing, skill-hooks-invocation-parity 2 passed against the real dist/cli.js, five further no-AK files 31 passed), but the credential-bearing interactive shards did not run, so the harness consumers that drive a real model were exercised statically only.

Not explored to full depth (tool budget reached): "agent 6b": confirming whether any current interactive test leaks two or more sessions into one TestRig.cleanup() (which would make the serial await inside the loop exc….

Not reviewed: reverse audit — stopped before round 4 by the review time budget.

Residual risk: this loop is persistently critical — Criticals stood in the previous round's work-list and stand again this round (1 Critical(s)), the rate of first-time findings is not falling (this round 0, previous 0), and the standing Critical backlog is not shrinking. The severity floor will not converge it. Recommendation: land-with-residual-risk — the exit is a maintainer risk-acceptance decision (merge, carrying the residual risk), not another review round. Residual-risk inventory for that decision (maintainer to complete):

Advisory only — it does not block this review.

[Critical] R16-1: [certifies-falsely] [new-surface] The PR description still certifies Fixes #10990 in BOTH mirrors — the English ## Linked Issues (body line 62) and the Chinese ## 关联 Issue (body line 128) — but the archived logs of both jobs that trailer rests on name a failing in-test-body assertion and contain zero EPIPE and zero unhandled occurrences, so merging as written records a root-cause fix for a failure class neither job exhibited. This is the tenth consecutive round in which it is the only standing blocker; the code-side (#10990) attributions were dropped in 4e37d2e4a4 (git grep -n 10990 HEAD returns 0 hits), and the teardown wait itself is sound and was measured working again this round. Nothing needs reverting except the attribution, and the edit needs a human: the author's own round-9 handoff records that the AutoFix loop has no GitHub credentials and that qwen-autofix.yml exposes no PR-body update path in any mode. Issue #10990's two named jobs are 100890051410 and 100890051579 in run 33829764813 at commit b7815a7e1a82. Both end on FAIL interactive/mid-turn-submit-interactive.test.ts > Mid-turn submit > exits on /quit while the response stream is held mid-turn, an assertion recorded inside the test body (submitUntilMidTurn at :162-165, called from the it at :208), so it fires before the file's afterEach (:83-90) runs — while await rig.cleanup() lives only in that afterEach (:89) and test-helper.ts:575 is the only wait this diff adds. The incident therefore completes identically after this change. The per-commit filing came from the detector's own documented missing-log fallback in .github/workflows/main-ci-failure-issue.yml (a file this diff does not touch). A maintainer closed #10990 on 2026-09-05 as a superseded per-commit E2E alert, so merging cannot close it; the harm is the false root-cause certification left in the PR record and in any squash message carrying the body, while the recurring OpenTUI mid-turn signature and the detector's log-fetch fallback both ship untouched and untracked. Fix: Keep the wait — it is justified on the orphan measurement the description already contains (a CLI child reparented to init at worker teardown). Drop Fixes #10990 from BOTH body mirrors (removing only one leaves the close-on-merge claim standing) and keep the trailer out of the merge message. Restate the ## Why it's needed premise to what the logs show: a named in-test-body assertion in mid-turn-submit-interactive.test.ts, plus the detector's missing-log fallback as the reason the issue named no test. Correct the second-job paragraph (its archived log shows the same mid-turn assertion as its only failure, and what starved was a retry of that named test, not 'the documented transient shared-host pressure class') and drop the pointer to #10994, which is itself closed. Drop the ## Risk & Scope sentence claiming external-context-mem0-write.test.ts 'never applies the renderer overlay' — at HEAD :491-501 spawns with resolveE2eCliCommand(renderer) and ...e2eRendererEnv(renderer). Do not date the OpenTUI recovery to 56f75adf29: that commit's own OpenTUI leg (job 100909628476) still reddened on the same signature. If a tracker is wanted, point it at the recurring OpenTUI mid-turn byte-contiguity signature or at the detector's log-fetch fallback. Fix constraint: integration-tests/test-helper.ts:566 reads // writes EPIPE and fail an otherwise all-green run (#10969). Signalling at HEAD and is correct — #10969 is the real closed alert whose EPIPE mechanism PR #10971 addressed; it must NOT be changed to #10990 or removed as part of this edit. Do not drop the wait to drop the attribution: integration-tests/test-helper.ts:172 const gone = childExited && !sessionAlive(pid); is what the case waits for the CLI the installed bin wrapper relaunched to end pins, and removing the process-group gate reddens it with expected 201 to be greater than or equal to 750. .github/scripts/ci/main-failure-signature.mjs is untouched by this diff and must stay so — its VITEST_FAIL_PATTERN at :41 does match the space-prefixed vitest FAIL line once cleanLine() at :49-55 strips ANSI, a leading timestamp and collapsed whitespace.

5 Suggestion-level finding(s) this review confirmed are already reported on this PR and are not repeated:

• R15-11 new stand-in tests assume POSIX signal semantics with no win32 skip — already reported (comment 5549153747, round-8 deferred list)

Not reviewed: build-and-test — Integration Tests (CLI, No Sandbox) was skipped in CI and its full cli suite did not run locally; the changed file's own suite (11/11) and 8 TestRig consumer suites (84/84) did run green locally.

Not explored to full depth (tool budget reached): "agent 6c": could not execute integration-tests/test-helper.test.ts — this review worktree has no node_modules ( ls node_modules/vitest → not found), so the real-lane ….

Not reviewed: reverse audit — stopped before round 3 by the review time budget.

Deferred under the convergence posture (round 26, not a blocker) — recorded, not requested in this round:

• integration-tests/test-helper.test.ts:187 — [probe] D26-2 the give-up test's KEEP_OUTPUT=true disables the post-loop work the warning promises

Fix witness: N/A — a PR-body attribution edit adds no guard, branch or behaviour a test can pin, and that absence is itself corroborating: all three cases this diff adds stay green whether or not the OpenTUI leg's real failure is addressed.
