fix(test): end interactive PTY sessions a test never closed - #10971
Conversation
The `E2E Interactive - OpenTUI renderer (bun)` leg exits non-zero without printing a single `FAIL` line, so the main-CI-failure detector has no test to dedupe on and files it per commit (runs 33806428062, 33797332289, 33765773571). Its failing step also runs as long as a healthy one — 152-190s against 86-192s — so every test passes and the run then dies on what vitest reports as an unhandled error rather than a failure. `TestRig.runInteractive()` hands the caller the PTY handle and keeps no record of it, and `cleanup()` only removes the test directory — which it skips entirely under the `KEEP_OUTPUT=true` this leg sets. Two interactive files never kill the child they spawned, so a live CLI session survives to the end of the run still forwarding every PTY byte into `process.stdout` through the `VERBOSE`/`KEEP_OUTPUT` branch of its `onData` handler. Once vitest tears the worker down the reader end of that pipe is gone and the next write raises EPIPE as an `'error'` event on `process.stdout`; with no listener Node escalates it to an uncaught exception (measured: a child writing into a destroyed stdout pipe exits through `uncaughtException` with `code=EPIPE`). That is fatal on this leg alone. `dangerouslyIgnoreUnhandledErrors` is off for github-hosted Linux, and the OpenTUI job is the only Linux lane that is github-hosted: the shards moved to the self-hosted pool (#10085) and macOS is exempt by platform, so both already swallow this class. Track what `runInteractive()` spawns and kill it in `cleanup()`, ahead of the directory removal that a live child writing into it could also race. The witness test pins this with a stand-in for the CLI bundle and fails on the previous harness — the child outlives `cleanup()` through all three of vitest's retries.

Confidence: 4/5 — clean, minimal, and correct on its own terms; the one thing I cannot read here is whether it actually retires the intermittent red. Stepping back: the reason I'm comfortable is that the change is a strict improvement independent of whether the EPIPE attribution is exactly right. A harness that lets a test's PTY child outlive the test is a defect on its own terms — every consumer of I also did not have to take the diagnosis on faith. Each link is checkable in the tree — the byte-forwarding under The witness is the part that most often turns out to be decorative on harness PRs, and this one is not: nothing else in the rig ends that child, so removing the kill loop is precisely the failing state. It also needs no credentials, no network, and no My reservations, all non-blocking and all named in the review above: What I genuinely cannot settle from here is efficacy against the intermittent failure, and that is structural rather than a gap in the PR: Verdict: approve, deferred.

1. What actually failed in #10969 (blocks the Fixes claim)
Every one of the three red E2E Interactive - OpenTUI renderer (bun) runs the PR cites failed the same test, three attempts each, with a real assertion:
| Run | Commit | Result |
|---|---|---|
| 33806428062 (job 100817894031, the one #10969 names) | f6a7eee341 |
FAIL interactive/mid-turn-submit-interactive.test.ts > Mid-turn submit > exits on /quit while the response stream is held mid-turn — Held response never reached the screen ×1, /quit did not exit while the stream was held ×2; Test Files 1 failed | 8 passed | 1 skipped (10), Tests 1 failed | 17 passed | 2 skipped (20) |

| 33765773571 (job 100695676098) | 0d69691f2c |
same test, same shape |
grep -ci 'unhandled\|EPIPE' over all seven downloaded logs (3 red + 4 green) is 0. The vitest summary in each red run reports 1 failed, i.e. the non-zero exit is a plain test failure, not "an unhandled error on an all-green run".
The green runs tell the rest of the story: in every green OpenTUI run that already had mid-turn-submit-interactive.test.ts, the /quit case passed only on retry (37689ms (retry x1), 39611ms (retry x1), 74069ms (retry x2)), while on the same commit the ink-renderer legs (self-hosted Linux and macOS) pass it in ~3s with no retry. The red runs are simply the runs where all three attempts lost the race. The CI debug dumps show what the race is: the CLI reports ✖︎ Chat not initialized when the test types Start the review. right after Type your message appears, so the held response never renders and /quit has nothing mid-stream to exit from. That is an OpenTUI/bun readiness race on a slow hosted runner, and this PR does not touch it.
2. Why #10969 carried no test name (a detector gap, contrary to the description)
The description argues the missing FAIL line is "a real property of the run and not a gap in the detector". The main-ci-failure-issue.yml run that filed #10969 (run 33809587872, step Identify the failing tests) shows otherwise:
Failed jobs: 1
the response contains terminal escape sequences; pass --allow-escape-sequences to output it anyway
##[warning]Could not download the log of job 100817894031
Failing tests identified: 0
The hosted runner's newer gh refuses to emit a log that contains terminal escape sequences unless --allow-escape-sequences is passed, and the OpenTUI leg's log is full of them because VERBOSE/KEEP_OUTPUT forward every PTY byte. With no log, the helper had nothing to parse and fell back to the per-commit issue. I ran .github/scripts/ci/main-failure-signature.mjs (this branch's copy) locally against the same three downloaded logs and it extracts interactive/mid-turn-submit-interactive.test.ts > Mid-turn submit > exits on /quit … from all three, so the parser is fine — the download is the gap. One-line fix in the workflow: add --allow-escape-sequences to the gh api …/logs call.
3. The harness change itself — all claims reproduce
- Regression test, red/green. PR head:
test-helper.test.ts7 passed (7), 3.1s. Negative control (git checkout f6a7eee341 -- integration-tests/test-helper.ts, PR test kept): exactly the new case fails on all three attempts withAssertionError: the interactive CLI child outlived cleanup(): expected true to be false,1 failed | 6 passed (7), 33s. Restored afterwards. - OpenTUI (bun) leg, base vs PR — the leg the PR could not run: both arms
Test Files 9 passed | 1 skipped (10),Tests 18 passed | 2 skipped (20), exit 0, ~90s; same ten files, same skips. The/quitcase passes in ~2s on this machine in both arms, so the CI flake is a runner-speed effect (see §5). Ink leg on the PR head: same 9/18 shape, exit 0. - Process table. A 1s
pssampler over the two legs (image below) shows the leak the PR describes and shows the fix ending it: on base the firstcontext-compress-interactivesession stays alive 38s after its own case finished and overlaps the next case's session until the worker is torn down (82s and 37s, both still present at teardown); on the PR the first session ends the second its case'scleanup()runs and never overlaps the next one.hooks-command's leaked session lives ~3s in both arms because its file ends immediately after. eslint --max-warnings 0on the two changed files andtsc -p integration-tests/tsconfig.json --noEmit: clean. Bundle boots undernodeand underbunwithQWEN_TUI_RENDERER=opentui QWEN_TUI_RENDERER_STRICT=1.
4. The EPIPE mechanism does not reproduce
The description says the leaked child's writes EPIPE after vitest tears the worker down, and that this "was measured directly". I could not reproduce it, and the CI logs never showed it. On the base harness (no fix), interactive/hooks-command.test.ts alone — the file that leaks one session and finishes in 3s, i.e. the sharpest case for the mechanism — under KEEP_OUTPUT=true VERBOSE=true, three runs each under ink and under opentui/bun: exit 0 every time, no Unhandled in the output, and no CLI child left after vitest exits. The reason is mechanical: vitest's fork pool ends a finished worker with SIGTERM (tinypool terminate()), the worker dies before it can write again, the PTY master closes with it, and the leaked child gets SIGHUP. The leak is real (§3) but it is not what turned the leg red.
5. The real #10969 failure reproduces with this PR applied
To show the leg's failure mode without waiting for a slow hosted runner, I pinned the PR-head run of interactive/mid-turn-submit-interactive.test.ts alone (opentui/bun, CI env) to one core shared with two busy loops. That is harsher than a 4-vCPU hosted runner, and the result is correspondingly harsher, but it is the CI failure exactly: every one of the 12 attempts (4 cases × 3 tries) failed with AssertionError: Held response never reached the screen, so the turn is not mid-stream — the first of the two messages in the CI logs — and the debug dumps show the same screen the CI dumps show: > Start the review. ✖︎ Chat not initialized (24 occurrences). bootCli treats the Type your message placeholder as readiness; under OpenTUI on a slow core the prompt is accepted before the chat client exists, the fake server never receives a request, MID_TURN_HELD_MARKER never renders, and /quit has nothing to exit mid-stream from. This PR's cleanup() runs after all of that. (One run; the base arm was not repeated under contention since the PR does not touch this path.)
6. Non-blocking notes
InteractiveSession(integration-tests/interactive/interactive-session.ts, used bycron-interactive.test.ts) spawns its ownpty.spawnand is not registered ininteractiveProcesses, so the "a future test that forgets to close its session is covered too" guarantee only holds forrig.runInteractive()callers. Fine today (it closes infinally), worth a sentence in the description or a one-line registration.@lydell/node-pty'skill()isprocess.kill(this.pid, 'SIGHUP')with the error swallowed and no exited-guard, so "a second kill of an exited child is swallowed" really means "signals whatever now owns that PID, usually nothing". Dropping the entry in anonExithandler would make cleanup never touch a stale PID. Cosmetic on Linux with a 4Mpid_max, but cheap.- The PR's own CI reds are inherited, not introduced:
Test (ubuntu)fails twoInputPrompt.test.tsxcases andLint & Staticreports onereact-hooks/exhaustive-depswarning atInputPrompt.tsx:1892, both present at the basef6a7eee341and fixed onmainby fix(cli): complete the live slash-submit deps and fixture (#10944) #10961 (69c4f1e4bb). A rebase clears both.Dependency CVE auditis thejsdiffadvisory, unrelated.
Recommendation
Merge the harness change after editing the description: Fixes #10969 → Refs #10969, and replace the EPIPE narrative with what the logs show. Two follow-ups are the actual repair for #10969: (a) --allow-escape-sequences on the log download in main-ci-failure-issue.yml, so the next red run names its test; (b) make mid-turn-submit-interactive.test.ts' bootCli wait for chat readiness under OpenTUI (the Chat not initialized race) rather than for the Type your message placeholder. I can open either if useful.

对下载的全部七份日志(3 红 + 4 绿)grep -ci 'unhandled\|EPIPE' 结果为 0。每次红 run 的 vitest 汇总都写着 1 failed,也就是说非零退出码就是一次普通的测试失败,而不是"全绿 run 上的 unhandled error"。
绿色 run 补全了故事:凡是已经包含 mid-turn-submit-interactive.test.ts 的绿色 OpenTUI run,/quit 用例都是靠重试才通过(37689ms (retry x1)、39611ms (retry x1)、74069ms (retry x2));而同一 commit 上 ink 渲染器的 leg(self-hosted Linux 与 macOS)约 3 秒即过、无重试。红色 run 只是三次尝试都输掉竞争的那些 run。CI 的 debug 输出说明了竞争是什么:测试在 Type your message 出现后立刻输入 Start the review.,CLI 报 ✖︎ Chat not initialized,于是被扣住的响应根本没有渲染,/quit 也无所谓"中途退出"。这是 OpenTUI/bun 在慢速托管 runner 上的就绪竞态,本 PR 完全没有触及。
2. #10969 为什么没有测试名(与描述相反,这是检测器的缺口)
描述称缺少 FAIL 行"是该 run 的真实属性而非检测器的缺口"。创建 #10969 的 main-ci-failure-issue.yml run(33809587872,Identify the failing tests 步骤)显示恰恰相反:
Failed jobs: 1
the response contains terminal escape sequences; pass --allow-escape-sequences to output it anyway
##[warning]Could not download the log of job 100817894031
Failing tests identified: 0
托管 runner 上较新的 gh 在日志包含终端转义序列时拒绝输出,除非传 --allow-escape-sequences;而 OpenTUI leg 的日志里满是转义序列,因为 VERBOSE/KEEP_OUTPUT 会把每一个 PTY 字节转发出来。没有日志,helper 无从解析,只能退回按 commit 建 issue。我在本地用本分支的 .github/scripts/ci/main-failure-signature.mjs 跑同样三份下载的日志,三份都能提取出 interactive/mid-turn-submit-interactive.test.ts > Mid-turn submit > exits on /quit …,所以解析器没问题,缺口在下载。workflow 里一行修复:给 gh api …/logs 加上 --allow-escape-sequences。
3. harness 改动本身 —— 所有主张都复现
- 回归测试红/绿。 PR head:
test-helper.test.ts7 passed (7),3.1s。反向对照(git checkout f6a7eee341 -- integration-tests/test-helper.ts,保留 PR 的测试):恰好新用例三次尝试全失败,AssertionError: the interactive CLI child outlived cleanup(): expected true to be false,1 failed | 6 passed (7),33s。之后已还原。 - OpenTUI(bun)leg,base 对 PR —— PR 没能跑的那个 leg:两臂都是

4. EPIPE 机制无法复现
描述称泄漏子进程在 vitest 拆除 worker 后写入会 EPIPE,并且"是直接测量得到的"。我无法复现,CI 日志里也从未出现。在 base harness(无修复)上单独运行 interactive/hooks-command.test.ts —— 泄漏一个会话且 3s 内结束、对该机制最尖锐的用例 —— 在 KEEP_OUTPUT=true VERBOSE=true 下,ink 与 opentui/bun 各跑三次:每次 exit 0,输出里没有 Unhandled,vitest 退出后没有残留 CLI 子进程。原因是机械性的:vitest 的 fork 池用 SIGTERM 结束已完成的 worker(tinypool terminate()),worker 在再次写入之前就已死亡,PTY master 随之关闭,泄漏子进程收到 SIGHUP。泄漏是真的(§3),但它不是让 leg 变红的原因。
5. 应用本 PR 后,#10969 的真实失败仍能复现
为了不必等慢速托管 runner 就展示该 leg 的失败形态,我把 PR head 上单独运行的 interactive/mid-turn-submit-interactive.test.ts(opentui/bun,CI 环境)钉在一个与两个忙循环共享的核心上。这比 4 vCPU 的托管 runner 更严苛,结果也相应更严苛,但正是 CI 的那种失败:12 次尝试(4 个用例 × 3 次)全部以 AssertionError: Held response never reached the screen, so the turn is not mid-stream 失败 —— 即 CI 日志中两条信息里的第一条 —— debug 输出显示的也是 CI 输出里同样的屏幕:> Start the review. ✖︎ Chat not initialized(出现 24 次)。bootCli 把 Type your message 占位符当作就绪信号;在慢核上的 OpenTUI 里,提示词在 chat client 存在之前就被接受,假服务器从未收到请求,MID_TURN_HELD_MARKER 从未渲染,/quit 也就没有可以中途退出的东西。本 PR 的 cleanup() 在这一切之后才运行。(单次运行;base 臂未在限流下重复,因为 PR 不触及这条路径。)
6. 非阻塞备注
InteractiveSession(integration-tests/interactive/interactive-session.ts,cron-interactive.test.ts在用)自己调用pty.spawn,没有登记进interactiveProcesses,所以"将来忘记关闭会话的测试也会被覆盖"只对rig.runInteractive()的调用方成立。目前没问题(它在finally里关闭),值得在描述里加一句或补一行登记。@lydell/node-pty的kill()就是process.kill(this.pid, 'SIGHUP'),吞掉错误、没有已退出守卫,所以"对已退出子进程的第二次 kill 会被吞掉"实际是"给现在拥有该 PID 的进程发信号,通常是没人"。在onExit里移除条目可以让 cleanup 永远不碰过期 PID。Linux 上pid_max为 4M,属于外观问题,但代价很低。- PR 自己的 CI 红项是继承来的,不是引入的:
Test (ubuntu)挂的是InputPrompt.test.tsx两个用例,Lint & Static报的是InputPrompt.tsx:1892一个react-hooks/exhaustive-deps警告,两者在 basef6a7eee341上就存在,main上已由 fix(cli): complete the live slash-submit deps and fixture (#10944) #10961(69c4f1e4bb)修复。rebase 即可清掉。Dependency CVE audit是jsdiff公告,无关。
建议
修改描述后合入 harness 改动:Fixes #10969 → Refs #10969,并把 EPIPE 叙述替换为日志实际显示的内容。两个后续项才是 #10969 的真正修复:(a)在 main-ci-failure-issue.yml 的日志下载上加 --allow-escape-sequences,让下一次红 run 能写出测试名;(b)让 mid-turn-submit-interactive.test.ts 的 bootCli 在 OpenTUI 下等待 chat 就绪(Chat not initialized 竞态),而不是等 Type your message 占位符。需要的话我可以开这两个 PR。

What this PR does
Makes the interactive test harness end every terminal session it starts. The rig now remembers each pseudo-terminal child it spawns for an interactive run and terminates any that are still alive when the rig is cleaned up, before it removes the test directory. A child that already exited on its own is not treated as an error.
A regression test pins the behaviour with a stand-in for the CLI bundle, so the guarantee does not depend on a real model call or on which renderer is under test.
Why it's needed
The
E2E Interactive - OpenTUI renderer (bun)leg of the E2E workflow has been going red onmainwithout naming a single failing test — runs 33806428062, 33797332289 and 33765773571 all failed this way, interleaved with passing runs, which is why #10969 was filed per commit rather than against a test.Two properties of those failures narrow it down sharply. The failing step ran 152–190s while healthy runs of the same step took 86–192s, so the suite ran to completion rather than breaking at boot or collection. And the log carried no
FAILline at all, which is a real property of the run and not a gap in the detector: the failure-signature helper downloads each failed job's full log and does name tests when they exist, as 23 earlier issues show. A vitest run that passes everything and still exits non-zero is an unhandled error, not a test failure.The harness supplied the source. Two interactive files start a session and never end it, and the rig's cleanup only removed the test directory — which it skips entirely under the
KEEP_OUTPUT=truethis leg sets. A leaked CLI session therefore stayed alive to the end of the run, still forwarding every byte of terminal output into the worker's standard output, because the same environment enables that verbose forwarding. Once vitest tears the worker down, the reader end of that pipe is gone, and the next write raisesEPIPEas an unhandled error event that Node escalates to an uncaught exception. That was measured directly rather than assumed.This only ever turned one leg red, which is what made it look renderer-specific. Unhandled errors are non-fatal on macOS and on the self-hosted Linux pool — both were exempted deliberately, the pool under #10085 — and the OpenTUI job is the only Linux lane still running on a hosted runner with that exemption off. So a harness-wide leak surfaced exclusively as an OpenTUI failure.
Ending sessions in the rig fixes the class in one place: the two leaking files need no edit, and a future test that forgets to close its session is covered too. The renderer-policy question — whether hosted Linux should keep treating unhandled errors as fatal — is left alone on purpose, since that is a maintainer call about signal, not a defect, and the leak is the thing actually worth repairing.
Reviewer Test Plan
How to verify
The behaviour to confirm is that no interactive session outlives the test that started it.
Start from the regression test in the rig's own test file. On this branch it passes; check out the parent commit and run the same file, and it fails on all three of vitest's attempts reporting that the interactive CLI child outlived cleanup. That before/after pair is the whole claim, and it needs no model credentials, no
bun, and no network — the test substitutes an idle script for the CLI bundle because what is under test is that cleanup ends whatever the rig spawned.To confirm the wider suite is unaffected, run the interactive leg and compare against
main: the same ten files should be collected and the same eighteen tests should pass, with no new skips. This matters most for the sessions that are expected to end by themselves — the Ctrl+C exit case and the mid-turn/quitand bare-exitcases — since cleanup now kills children those tests already terminated. A second kill of an exited child is swallowed, and that path is exercised on every run of the leg.It is also worth watching the process table while the leg runs. On
main, CLI children spawned by the compression and/hooksfiles are still alive after their own test has finished; on this branch they are gone by the time the next file starts.The OpenTUI leg itself is the final check and needs
bun; it could not be run in the environment this change was prepared in. Because the failure is intermittent — it passed on four of the seven runs observed — a single green OpenTUI run does not prove much on its own. The meaningful signal is whether this leg stops producing the "exit code 1, no failing test" shape over a run of merges.Evidence (Before & After)
Non-UI change. The measured before/after is the regression test:
1 failed | 6 passed (7)—AssertionError: the interactive CLI child outlived cleanup(): expected true to be false, repeated across vitest's three attempts; file duration 43.51s.7 passed (7); file duration 8.43s, the drop being the retries that no longer happen.9 passed | 1 skipped (10)files,18 passed | 2 skipped (20)tests, exit 0 — matching the pre-change baseline of four consecutive green local runs.Tested on

中文说明
这个 PR 做了什么
让交互式测试框架结束它自己启动的每一个终端会话。rig 现在会记住它为交互式运行生成的每一个伪终端子进程，并在自身清理时终止所有仍存活的子进程，位置在删除测试目录之前。已经自行退出的子进程不会被视为错误。
一个回归测试用 CLI bundle 的替身把这一行为固定下来，因此该保证既不依赖真实的模型调用，也不依赖被测的是哪个渲染器。
为什么需要它
E2E workflow 的
E2E Interactive - OpenTUI renderer (bun)leg 一直在main上变红，却不指出任何一个失败的测试 —— run 33806428062、33797332289 和 33765773571 都是这样失败的，中间还夹着通过的 run，这正是 #10969 按 commit 而不是按测试来记录的原因。这些失败的两个特征让范围迅速收窄。失败的步骤耗时 152–190 秒，而同一步骤的健康 run 耗时 86–192 秒，所以套件是跑完了的，而不是在启动或用例收集阶段就崩掉。并且日志里完全没有
FAIL行，这是该 run 的真实属性而非检测器的缺口：失败签名助手会下载每个失败 job 的完整日志，且在测试名存在时确实会写出来，此前 23 个 issue 就是证明。一个所有测试都通过却仍以非零码退出的 vitest run，是 unhandled error，而不是测试失败。框架提供了来源。有两个交互式文件启动了会话却从不结束它，而 rig 的清理只删除测试目录 —— 在本 leg 设置的
KEEP_OUTPUT=true下连删除都完全跳过。因此泄漏的 CLI 会话会一直存活到 run 结束，并且仍在把每一个终端输出字节转发进 worker 的标准输出，因为同样的环境设置开启了这种冗长转发。一旦 vitest 拆除 worker，该管道的读取端就消失了，下一次写入会产生EPIPE，以未处理的 error 事件形式出现，并被 Node 升级为未捕获异常。这一点是直接测量得到的，而不是假设。这从来只会让一个 leg 变红，也正是这一点让它看起来像是渲染器特有的问题。unhandled error 在 macOS 和 self-hosted Linux 池上都不致命 —— 两者都是刻意豁免的，池是在 #10085 中豁免的 —— 而 OpenTUI job 是唯一仍跑在托管 runner 上、且未获得该豁免的 Linux 通道。于是一个框架级别的泄漏，只表现为 OpenTUI 的失败。
在 rig 中结束会话，一处就修掉了整类问题：两个泄漏的文件无需改动，将来忘记关闭会话的测试也会被覆盖。渲染器策略问题 —— 托管 Linux 是否应继续把 unhandled error 判为致命 —— 被刻意保留不动，因为那是维护者关于信号取舍的决定，不是缺陷；泄漏才是真正值得修的东西。
Reviewer 测试计划
如何验证
需要确认的行为是：没有任何交互式会话活得比启动它的测试更久。
从 rig 自己测试文件里的回归测试开始。在本分支上它通过；切到父提交运行同一个文件，它会在 vitest 的三次尝试中全部失败，并报告 interactive CLI child 活得比 cleanup 更久。这一组前后对照就是全部主张，且不需要模型凭据、不需要
bun、不需要网络 —— 测试用一段空闲脚本替代 CLI bundle，因为被测的是"cleanup 会结束 rig 生成的任何东西"。要确认更大的套件未受影响，运行 interactive leg 并与
main对比：应当收集到同样的十个文件、通过同样的十八个测试，且没有新增的 skip。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和裸exit用例 —— 因为 cleanup 现在会去 kill 这些测试已经终止过的子进程。对已退出子进程的第二次 kill 会被吞掉，而这条路径在每次运行该 leg 时都会被走到。也值得在该 leg 运行期间观察进程表。在
main上，由压缩文件和/hooks文件生成的 CLI 子进程在它们自己的测试结束后仍然存活；在本分支上，到下一个文件开始时它们已经消失。OpenTUI leg 本身是最终检查，需要
bun；在准备这一改动的环境中无法运行。由于失败是间歇性的 —— 在观察到的七次 run 中它通过了四次 —— 单独一次绿色的 OpenTUI run 说明不了太多。有意义的信号是：在若干次合并之后，这个 leg 是否不再产生"退出码 1、无失败测试"这种形态。证据（前后对比）
非 UI 改动。测得的前后对比就是那个回归测试：
1 failed | 6 passed (7)——AssertionError: the interactive CLI child outlived cleanup(): expected true to be false，在 vitest 的三次尝试中重复出现；文件耗时 43.51s。7 passed (7)；文件耗时 8.43s，下降部分正是不再发生的重试。9 passed | 1 skipped (10)个文件、18 passed | 2 skipped (20)个测试、exit 0 —— 与改动前连续四次本地绿色运行的基线一致。测试环境
环境（可选）
Linux（Node 22），
QWEN_SANDBOX=false，QWEN_E2E_RENDERER=ink，针对打包后的dist/cli.js运行。opentui渲染器 leg 未运行：该环境中没有bun，而渲染器矩阵在缺少它时会抛错。泄漏及其回归测试与渲染器无关 —— 渲染器只决定由哪个二进制驱动终端。风险与范围
bun下的 OpenTUI leg，以及 github-hosted Linux 是否应继续关闭dangerouslyIgnoreUnhandledErrors。E2E workflow 与 integration vitest 配置被刻意保持未改动；该 leg 是间歇性的，因此确认修复需要若干次 main 分支运行，而不是一次。关联 Issue
