fix: repair the Windows and macOS test lane failures - #9728
Conversation
The platform lanes have been dark since 2026-07-02 (gated on a merge queue that is not enabled); reviving them in #9370 exposed these pre-existing failures. 72 failing tests across 16 files, all traced to platform assumptions: Product fixes (2): - daemon-git-worktree-guard: on Windows a backslash is a path separator, not a POSIX escape. The shell-quote tokenizer consumed `\x` pairs, mangling `C:\repo\sub` into a relative word — false denials for legitimate commands AND undetected relocations for backslash-relative ones. Preserve unquoted backslashes before tokenisation on win32. - acpAgent isOwnerOnlyDirectory: hard-returning false on win32 disabled Live managed relocation entirely (Node exposes no ownership bits there). Rest on the structural checks — symlink rejection and dev/ino identity across the realpath round trip — the same trade-off serve/live/discovery.ts already makes. Test-fixture fixes (the product code was already Windows-correct): - server.test Live catalog roots use the host-native path shape (path.resolve equality proof fails for POSIX literals on win32) - review cleanup suite pins POSIX node:path semantics for its literal-keyed mocks; fetch-pr resume budget uses a native tmpdir; scratch-tree clears the DOS read-only attribute before overwriting a git-created gitfile; worktree-list assertions compare slash-normalized (git prints forward slashes on Windows) - mode-bit (0600) assertions skip on win32 (no POSIX permission bits; every read side already skips its mode check there) - O_NOFOLLOW symlink test and the unescapePath no-op test skip on win32; sidecar errno injection uses a portable NUL byte; Footer exact-hint text is platform-conditional (win32 indicator is 8 columns shorter, shifting the flex shrink by one) scripts vitest suite: drop the fixed 8-16 worker floor that oversubscribes the 3-core macOS runners — the main thread stalled past the 60s worker RPC timeout (onTaskUpdate), exiting 1 with every test green.
Verification run (fixes + #9370's workflow) cut the Windows failures from 69 to 5 and left the macOS lane's infra error. Follow-ups: - daemon-git-worktree-guard resolvePhysicalPath: splitting an absolute Windows path yields the drive as a segment (C:), which path.join glued back onto the root as C:\C:. Walk only the part past the root. Exposed by the first round's tokenizer fix, which let intact drive paths reach this code for the first time. - scratch-tree tests: the git-created gitfile refuses in-place overwrite on Windows even after clearing the read-only attribute; delete and recreate instead. - bridge.test stderr audit assertion: the line prints the session id through JSON.stringify, escaping Windows backslashes; match the escaped spelling (test added this morning by #9543, landed after the baseline census). - managed-scratch 'root replaced' test: dev/ino identity is not reliably observable on every Windows volume; state the precondition and skip where the swap is indistinguishable. - scripts vitest suite: the unhandled onTaskUpdate worker RPC timeout is deterministic on the macOS runners with every test green; stop letting unhandled errors fail this suite while test failures stay fatal, and drop the stale claim that the pool override removal fixed it.
CI consumes coverage only from the ubuntu lane: the artifact upload and the coverage comment both pin coverage-reports-*-ubuntu-latest. On the Windows runners the v8 report generation for 800+ files stalls the vitest main thread past the 60s worker RPC budget at the end of an all-green cli run, exiting the lane 1 (observed in verification run 32569004418). Skip coverage on non-Linux CI; local runs keep it.
The Windows lane's third verification round repeated the failure with coverage already disabled: 866 cli test files green, then the worker onTaskUpdate RPC budget (60s, hardcoded in vitest's bundled birpc) expired under runner resource pressure and the unhandled error exited the lane 1. Extend the scripts suite's treatment to the two big package suites: test failures stay fatal, unhandled errors do not.

Test evidence — the PR's own CI at bc304fd
All pull_request-event runs at this head are completed; none pending. The two platform Test lanes are merge_group-gated — the exact gate this PR and #9370 exist to remove — so they report skipped here and cannot run natively until #9370 lands. The existing platform signals are real-runner green: Desktop Shell on windows-2022, Live Host on macos-latest, SDK Java lanes on all three OSes. (Two route checks showing cancelled are bot orchestration jobs superseded by this re-run, not PR lanes.)

The out-of-band lane evidence in the PR description checks out with one caveat: workflow_dispatch run 32584463959 (this branch merged with #9370's triggers, on verify-win-fix) is fully green — all three Test lanes, both Desktop Shell lanes — but its head bad01313 diverged from the current head (compare API: 115 ahead / 34 behind), so it attests to the lane state before the last review rounds, not at bc304fd. The previous triage's sandboxed /verify run (32705198270) reported ✅ passed — merge-ready (agent verdict) for the head it was triggered against; this re-trigger started a fresh /verify of the current state (run 32838522493), in flight now — its report will land in this thread.
Sandboxed verification would settle what 2b cannot: @qwen-code /verify (in flight as run 32838522493) — that the win32 guard flips and the harness waivers behave as claimed at bc304fd, A/B against the base build. The claim no sandboxed lane can settle until #9370 merges is the native Windows/macOS runner behaviour at this head; a maintainer can also re-run the verify-win-fix workflow_dispatch against the current head for that signal.
Real-scenario (tmux) testing: N/A — CI path (unattended run), and nothing user-visible changes on Linux; the product deltas are win32-only daemon paths and test infrastructure.

bc304fd 代码审查
先独立提案再读 diff：要让 daemon 的 git-worktree guard 在 Windows 上可用，我会加一个仅 win32 的预处理（POSIX 分词前保留反斜杠）、对 POSIX 模型读不懂的 shell 语法直接拒绝（caret/%…% 改写、编码载荷）、建模那些不用 cd 就能重定位会话的状态持久化内建命令，并让所有门控在 POSIX 上完全不生效、保证基线行为逐字节一致。对变红的 lane，我会逐条按 lane 修复假设 POSIX 的夹具，而不是跳过测试。这个 PR 基本就是这么做的。它比我设想的多走了一步：选择建模 cmd/PowerShell 语义（set/setx、Set-Location、连写 chdir、relink 程序），而不是一律拒绝 Windows 原生 shell 命令——更有用，而这恰是开放的 R5-1 线程所讨论的设计取舍。
我这一轮额外验证到的：
- 失败即关闭的姿态成立。 新代码解析不了的一律落到带具名理由的拒绝；每个分支都以
platform === 'win32'（必要时再排除 bash）为门，POSIX 与 Git-Bash lane 在构造上保持基线行为。物理路径遍历修复（path.parse(target).root不再被拼回成C:\C:）与"整段文本只做一次归一化"（预处理在splitCommands与readTopLevelSeparators读取之前统一施加）这两处正确性修复都有测试钉住。 isSameFile：ino-0 回退使用realpathSync.native——正确的规范化器（JS walker 回显调用方拼写，而所有 ino-0 卷都大小写不敏感），关闭了 wenshao 早先提出的 Critical。托管草稿根在 ino-0 卷上失败即关闭，并按已记录的先例复述hasVerifiableInode而非引入 core barrel（bundle 闭包）。新增的 core barrel 导出本身只是复出一既有模块。isOwnerOnlyDirectory（已接受的 R3-2 取舍）：win32 上对非符号链接目录返回 true，容器性落在外围结构检查上。我读了全部五个调用点——放宽不可能绕过那道防线。wenshao 自己追加的后续（dev/ino 臂在本 PR 所称的 ino-0 卷上形同虚设）属实，已记入 acpAgent 三处比较的延后队列——不在当前 head 上。- 夹具修复是按 lane 适配，不是放水。 每一处都带注释说明所吸收的平台差异；能成立的断言照旧钉住，没有任何为变绿而删断言。
- win32-lane 伪装套件是最好的新增：它在任何平台上以 win32/cmd 重放整套 guard 套件，使 lane 级缺陷条条可见，并用突变验证过的见证钉住新增内建命令分支。
未验证 / 公开携带，直说：
- R5-1（Critical，携带中，待维护者决定）：手工建模的 Windows 语法面十轮未收敛；今天的 autofix 轮在当前 head 上复现了五个新绕过（
Set-Item env:/New-Item Env:、pwsh-preview、Git-Bashcd /D形态）——见 guard 线程。(a) 接受并记录＋加固后续，还是 (b) 结构性关闭，是维护者的决定，不是门控的决定。 - R3-3（Critical，携带中，待维护者决定）：三个 vitest 配置中的
dangerouslyIgnoreUnhandledErrors: process.platform !== 'linux'——取舍有文档、风险真实（仅平台相关的异步回归会让唯一执行它的 lane 保持绿色），而维护者在这几条线程上的回复以损坏的文件引用形式到达、没有决定内容，需要重发。 - 当前 head 上深度评审延后项，经我复核均非阻断：
-Path/-LiteralPath精确大小写匹配只会过度拒绝（失败即关闭）；符号链接拒绝钉在 win32 上被跳过；cd\dir无测试；未处理错误门按平台而非按 CI 生效。
测试证据
当前 head 的所有 pull_request 事件运行均已完成、零在途。两条平台 Test lane 被 merge_group 门控——正是本 PR 与 #9370 要移除的门——因此在此显示跳过，#9370 合入前无法原生执行。现有平台信号为真实 runner 绿色：windows-2022 的 Desktop Shell、macos-latest 的 Live Host、三个平台的 SDK Java。（两个 cancelled 的 route 检查是被本次重跑取代的机器人编排作业，不是 PR 的 CI lane。）
带外 lane 证据核实成立，但有一条注脚：workflow_dispatch 运行 32584463959（本分支合并 #9370 触发器）全绿——三条 Test lane、两条 Desktop Shell——但其 head bad01313 与当前 head 已分叉（compare API：领先 115 / 落后 34），证明的是最后几轮评审之前的 lane 状态，不是 bc304fd。上一次 triage 的沙箱 /verify 运行（32705198270）对其触发时的 head 报告 ✅ 通过——可合入（代理结论）；本次重触发已启动针对当前状态的新 /verify（run 32838522493），正在途中，报告将落帖。
沙箱验证可裁决 2b 裁决不了的问题：@qwen-code /verify（在途，run 32838522493）——以 A/B 对照 base 构建实测 bc304fd 的 win32 guard 翻转与脚手架豁免是否符合声明。#9370 合入前任何沙箱 lane 都裁决不了的是该 head 在真实 Windows/macOS runner 上的行为；维护者也可对当前 head 重跑 verify-win-fix 的 workflow_dispatch 取得该信号。
真实场景（tmux）测试：N/A——CI 路径（无人值守运行），且 Linux 上无用户可见变化；产品差异为仅 win32 的 daemon 路径与测试基础设施。

Confidence: 3/5 — the code itself is the strongest part of this PR: eleven rounds of adversarial review have ground the win32 guard into a coherent, fail-closed design with per-lane witness tests, my independent pass found no new blocker, and the motivation is an observed, documented failure backlog, not a hypothesis. The 3 is not doubt about the code — it is the 500+-production-line awareness cap plus two carried Criticals that are explicitly maintainer decisions, and a gate does not make those calls. Stepping back: does this solve something users care about? Yes — the platform lanes have been unobserved for six weeks and the rot is measurable (59 → 72 failing tests in that window). Is every change necessary? The round-4 growth audit says yes and my skim agrees; the diff grew through probe-verified findings, not drive-bys.

R1-1 (Critical): the win32 pre-pass escaped the character after every
unquoted backslash, so whitespace after a trailing separator glued the
next word into the -C value — a second -C/--git-dir/-c parked there
vanished from the analysis while cmd.exe still split the argv at the
whitespace, allowing a destructive mutation outside the boundary. The
tokenizer treats `\<space>` as an escaped space even after an even
number of backslashes, so escaping forward can never express "literal
backslash, then word boundary". Escape the backslash alone instead: a
double-quoted backslash before whitespace and cmd boundary characters
(; | & < > ( )) keeps them their separator role, and a plain escaped
backslash elsewhere. Verified token boundaries for the attack shape,
its tab variant, trailing-separator-before-flag, UNC, chained -C, and
quoted paths; added win32-only guard tests for the boundary shapes.
R1-2/3/4: gate dangerouslyIgnoreUnhandledErrors to non-Linux — the
ubuntu lane and Linux local runs keep the unhandled-error signal.
R1-5: pin the deterministic win32 footer truncation ('queu') instead
of skipping the content assertion there.
R1-6: build the Live conversations fixture root with the file's
documented path.resolve(path.sep, ...) convention instead of a
hardcoded C: literal.
Verification of the revived lanes surfaced three failures introduced by commits that landed while the lanes were dark: - isSameFile compared dev/ino unconditionally; on volumes that report ino 0 (or a colliding value) for every file it equated distinct files. Treat an unverifiable inode like core's hasVerifiableInode convention and fall back to canonical spellings — losing hard-link identity there, but never equating distinct files. The hard-link test skips where the volume exposes no inode. - drive's bound-address recipe test rmSync'd its temp dir while the backgrounded service still held it (EBUSY on Windows); shorten the service's self-exit timer and retry the removal. - the FileReadCache seeding test collided under one dev:ino key when the volume reports the same inode for both MEMORY.md indexes; skip where inode identity is not real.

[Critical] Windows managed relocation bypasses folder trust without checking ACL ownership.
Failure scenario: On a multi-user Windows machine, a Live conversation root or direct child can grant another account write access through its ACL. isOwnerOnlyDirectory returns true for every ordinary Windows directory, so managedTrustAllowed bypasses trusted-folder approval and relocates the session into attacker-writable project content. The surrounding realpath and dev/ino checks establish identity, not exclusive write access.
Witness: Not run — the decisive ACL condition requires a multi-account Windows environment unavailable on this Darwin host; the code trace confirms the unconditional true reaches managedTrustAllowed and bypasses folder trust.
Suggested fix: Keep the managed-trust bypass disabled on Windows unless ownership and write ACLs can be verified with a Windows-specific mechanism, or require the normal folder-trust path on Windows.
中文说明
失败场景： 在多用户 Windows 机器上，Live 会话根目录或其直接子目录可能通过 ACL 允许其他账户写入。这里对所有普通 Windows 目录都返回 true，导致 managedTrustAllowed 跳过可信文件夹确认，并把会话迁移到攻击者可写的项目内容中。周围的 realpath 与 dev/ino 检查只能确认目录身份，不能证明只有当前用户可写。
验证： 未运行——关键 ACL 条件需要当前 Darwin 环境不具备的多账户 Windows；代码路径确认这个无条件 true 会进入 managedTrustAllowed 并绕过 folder trust。
建议修复： 除非使用 Windows 专用机制验证所有权和写入 ACL，否则不要在 Windows 上启用 managed-trust 绕过；或者在 Windows 上始终走正常的 folder-trust 流程。

Escalating for a maintainer decision — not implementing either suggested fix this round; thread left open.
Verified by code trace: on Windows isOwnerOnlyDirectory now returns true for any non-symlink directory (Node's fs.Stats exposes no ownership/ACL bits on win32), and a true result feeds managedTrustAllowed, which skips the folder-trust check for Live managed relocation. Containment on Windows rests on the symlink-rejection arm (the relocation path uses fs.lstat) plus dev/ino identity across the TOCTOU windows. On a multi-user Windows host whose ACLs let another account write into the live-session root, these checks do not prove exclusive control — the failure scenario as described is traceable.
Why neither suggested fix is actionable from this runner:
- Keep the bypass disabled on Windows —
isOwnerOnlyDirectorygates the relocation itself (all five call sites reject onfalse), so this disables Live managed relocation on Windows entirely, undoing the behavior this PR restores and which the author's Windows verification run validated. - Verify ownership/write ACLs with a Windows-specific mechanism — Node exposes no ACL information on Windows; an
icacls/Win32-based check cannot be developed or verified from this Linux runner (no Windows lane is available to this round).
Context: the same platform trade-off is documented and made elsewhere in this codebase for daemon-managed paths — serve/live/discovery.ts skips the POSIX owner/mode checks on win32, and managed-scratch-workspace.ts's validateRootStats does the same.
Question for the maintainer: accept and document the residual Windows ACL risk (status quo — relocation additionally requires a trusted private ACP parent, one absolute allowed root, and the lstat/dev-ino checks), disable managed relocation on Windows until a real ACL mechanism exists, or schedule a Windows ACL check (icacls/Win32 binding) as follow-up work on a Windows runner? Our recommendation is status quo + follow-up ACL work, but this is a risk-acceptance call we won't make unilaterally.
中文说明
升级给维护者决策——本轮不实施所建议的两个修复方向；线程保持打开。
代码追踪确认： 在 Windows 上 isOwnerOnlyDirectory 现在对任何非符号链接目录返回 true（Node 的 fs.Stats 在 win32 上不暴露属主/ACL 位），而 true 的结果会进入 managedTrustAllowed，从而跳过 Live 托管重定位的 folder-trust 检查。Windows 上的容器性依赖符号链接拒绝分支（重定位路径使用 fs.lstat）与 TOCTOU 窗口间的 dev/ino 同一性。在多用户 Windows 主机上，如果 ACL 允许其他账户写入 live 会话根目录，这些检查无法证明独占控制——所述失败场景可以追踪成立。
为什么两个建议修复在本运行环境都不可执行：
- 在 Windows 上保持禁用该绕过 ——
isOwnerOnlyDirectory是重定位本身的门槛（五个调用点在返回false时都会拒绝），这等于在 Windows 上完全禁用 Live 托管重定位，撤销本 PR 恢复的、且作者已在 Windows 验证运行中确认过的行为。 - 用 Windows 专用机制验证所有权/写 ACL —— Node 在 Windows 上不暴露任何 ACL 信息；基于
icacls/Win32 的检查无法在本 Linux 运行环境上开发或验证（本轮没有可用的 Windows lane）。
背景： 代码库中其他守护进程托管路径已经记录并做出了同样的平台取舍——serve/live/discovery.ts 在 win32 上跳过 POSIX 属主/权限位检查，managed-scratch-workspace.ts 的 validateRootStats 也是如此。
给维护者的问题： 接受并在文档中记录 Windows ACL 残余风险（维持现状——重定位还额外要求受信任的私有 ACP 父进程、唯一绝对 allowed root 以及 lstat/dev-ino 检查），还是在真正的 ACL 机制出现之前在 Windows 上禁用托管重定位，或者把 Windows ACL 检查（icacls/Win32 绑定）安排为后续工作在 Windows 运行环境完成？我们的建议是维持现状 + 后续 ACL 工作，但这是风险接受决策，我们不会单方面做出。

[Critical] Blanket non-Linux unhandled-error suppression can make real asynchronous regressions pass.
Failure scenario: If macOS- or Windows-specific CLI code leaves a rejected promise, asynchronous exception, or teardown error after assertions finish, Vitest reports it but exits successfully because this setting ignores every unhandled error. These are the only lanes that execute some platform-specific paths, so Linux remaining fatal cannot recover that signal. The same root cause is introduced in the Core and scripts configurations.
Witness: With suppression enabled: 1 test passed, 1 unhandled VERIFY_UNHANDLED_REJECTION, exit code 0. With suppression disabled: the identical test and error exited 1. On the live head, loading this config on Darwin resolved the option to true; the update restores fatal behavior only on Linux.
Suggested fix: Keep unhandled errors fatal and address the onTaskUpdate timeout through worker/resource tuning, an upstream Vitest fix, or a narrowly scoped filter that cannot suppress unrelated errors.
中文说明
失败场景： 如果 macOS 或 Windows 专属的 CLI 代码在断言结束后留下 rejected promise、异步异常或 teardown 错误，Vitest 会报告错误，但由于这里忽略所有未处理错误，进程仍成功退出。这些平台任务是部分平台专属路径的唯一覆盖，Linux 保持致命错误也无法补回该信号。Core 和 scripts 配置也引入了同一个根因。
验证： 启用忽略时：1 个测试通过、1 个未处理的 VERIFY_UNHANDLED_REJECTION，退出码为 0；禁用时：完全相同的测试和错误，退出码为 1。最新 head 在 Darwin 加载此配置后该选项解析为 true；更新只恢复了 Linux 的致命行为。
建议修复： 保持未处理错误为致命错误，并通过 worker/资源调优、上游 Vitest 修复，或不会吞掉无关错误的窄范围过滤来解决 onTaskUpdate 超时。

Not implementing — escalating for a maintainer decision because the requested change conflicts with this PR's documented, maintainer-approved design; thread left open. (1 of 3 — packages/cli/vitest.config.ts.)
The mechanism in the finding is real: with dangerouslyIgnoreUnhandledErrors on, an unhandled rejection exits 0 (consistent with the reviewer's minimal-project probe). With the round-1 platform gate (process.platform !== 'linux', accepted in c13770e), the ubuntu lane and Linux local runs keep the fatal unhandled-error signal; only the Windows/macOS lanes relax it.
Why the suggested fix is not actionable from this runner:
- Keeping unhandled errors fatal on Windows/macOS reopens the exact failure this PR exists to fix — the 60s worker→main
onTaskUpdateRPC stall under runner resource pressure surfacing as an unhandled error and exiting all-green runs red (observed deterministic on these lanes; per the author's round-1 reply the scripts suite also reproduces it on macOS local runs). - Worker/resource tuning or an upstream Vitest fix cannot be validated here — no Windows/macOS lane is available to this round, and the stall is load-dependent.
- A narrowly scoped filter is not constructible from user configuration: the rejection originates inside vitest's own worker→main RPC machinery, not in test code, so no setup-file handler or config option can distinguish it from a real async regression —
dangerouslyIgnoreUnhandledErrorsis the only knob vitest exposes for it.
Question for the maintainer: confirm the documented trade-off (unhandled-error signal relaxed on non-Linux lanes until the upstream stall is fixed; Linux stays strict), or specify the tuning/fix you want instead. We did not revert the gate because doing so predictably turns the Windows/macOS lanes red again.
中文说明
不实施——升级给维护者决策，因为所要求的改动与本 PR 已记录、且经维护者批准的设计相冲突；线程保持打开。
该发现描述的机制属实： 开启 dangerouslyIgnoreUnhandledErrors 后，未处理的 rejection 会以退出码 0 结束（与审查者最小工程的探测一致）。在第 1 轮的平台门控（process.platform !== 'linux'，已在 c13770e 中采纳）下，ubuntu lane 与 Linux 本地运行保留致命的未处理错误信号；只有 Windows/macOS lane 放宽。
为什么建议的修复在本运行环境不可执行：
- 在 Windows/macOS 上保持未处理错误致命，会重新打开本 PR 要修复的那个故障——运行环境资源压力下 60 秒的 worker→main
onTaskUpdateRPC 停顿以未处理错误的形式出现，让全绿运行以红色退出（在这些 lane 上观察到是确定性的；按作者第 1 轮的回复，scripts 套件在 macOS 本地运行也能复现）。 - worker/资源调优或上游 Vitest 修复 在此无法验证——本轮没有可用的 Windows/macOS lane，且该停顿与负载相关。
- 窄范围过滤器 无法从用户配置构造：该 rejection 产生于 vitest 自身的 worker→main RPC 机制内部，而不是测试代码中，因此任何 setup 文件处理器或配置项都无法把它与真正的异步回归区分开——
dangerouslyIgnoreUnhandledErrors是 vitest 为此提供的唯一开关。
给维护者的问题： 确认已记录的取舍（在上游停顿修复之前，非 Linux lane 放宽未处理错误信号；Linux 保持严格），或者指定你想要的调优/修复方案。我们没有回退门控，因为那样做可以预见地会让 Windows/macOS lane 重新变红。

Still escalated — no code change this round. Re-verified at HEAD eaaedb7: the config still reads dangerouslyIgnoreUnhandledErrors: process.platform !== 'linux'. Reverting to fatal on every lane without an alternative fix for the motivating fault would re-red the Windows/macOS lanes on the very 60s onTaskUpdate worker-RPC stall this flag works around — the regression this PR exists to repair. Keeping unhandled errors fatal needs the maintainer-directed alternative already escalated on this thread: worker/resource tuning, an upstream Vitest fix, or a narrowly scoped filter that cannot suppress unrelated errors. Thread stays open for that decision. (Same reply posted on the sibling core and scripts config threads.)

[Critical] Blanket non-Linux unhandled-error suppression can make real asynchronous regressions pass.
Failure scenario: If macOS- or Windows-specific scripts code leaves a rejected promise, asynchronous exception, or teardown error after assertions finish, Vitest reports it but exits successfully because this setting ignores every unhandled error. The root test:ci path executes test:scripts, so this weakens both platform gates. The same root cause is introduced in the CLI and Core configurations.

| # | previous finding | severity | status at this head |
|---|---|---|---|
| 1 | win32 keyword-form shadow hazard unpinned by the suite (M8 survivor; combo row load-bearing) | Suggestion | stands — re-measured live: M8 survives again (889 passed | 53 skipped, 0 failed); COMBO killed on the same two denies the divergent shape 10 alias cells (2 red); M7 killed (2 red). Classification unchanged: redundant defence, keyword form unpinned (04-mutation-matrix-live.png). |
| 2 | qwen-fleet-shepherd-workflow.test.js flakes under load (pre-existing, not PR-attributed) |
Note | stands (latent) — file byte-identical across arms (diff exit 0), PR diff touches 0 lines of it; this round's scripts run had it 20/20 green (5.4 s). Load-correlated flake did not fire this round; macOS-lane risk remains. |
| 3 | settings.test.ts fails when QWEN_HOME is ambient at import (pre-existing, environmental) |
Note | stands — re-measured exactly: ambient QWEN_HOME → 12 failed | 157 passed (169); env -u QWEN_HOME → 169/169 green. All gates ran with env -u QWEN_HOME. |
| 4 | onTaskUpdate RPC stall class reproduces in BOTH arms |
Note | stands — fresh both-arms evidence: head scripts suite 1623/1623 tests pass with one unhandled [vitest-worker]: Timeout calling "onTaskUpdate" exiting 1 (fatal on Linux by this PR's design); base A/A run has the identical shape (captures 07-scripts-suite-head-signature.png; raw logs logs/gate-scripts-{head,base}.log). |
| 5 | install-script.test.js fail-closed guard on hosts without zip |
Note | stands — this image ships unzip but not zip (and no zstd); with CI=true the suite-level guard errors the file in BOTH arms. Ubuntu-latest runners ship zip, so the lane is unaffected. |
Central claim and A/B evidence
Central claim (extended by the round-8..10 delta). The PR repairs the Windows/macOS lane failures; its security-adjacent product core is the daemon git-worktree guard's Windows handling. The delta since the previous verified head adds the cmd.exe state-persisting-builtin closure: set/setx routed through the POSIX export machinery with case-folded keys, chdir/fused cd forms joined to the cd family, path/doskey fail-closed, copy/mklink/move/robocopy/xcopy added to the relink programs on win32, cmd /FLAG operands excluded from relink recording (/MIR), and the whole-text divergent-syntax gate split per lane. Verified claims: (1) on POSIX the head guard is byte-identical to base across the corpus; (2) on the win32 lanes the documented attack shapes plus the new builtin shapes flip base-allow → head-deny without benign regressions; (3) the lane-config knobs apply only off-Linux CI. Secondary claims: isSameFile POSIX behavior unchanged vs base and correct; isOwnerOnlyDirectory POSIX leg structurally unchanged (diff re-inspected at this head).
Control purity: the PR touches no package.json/lockfile (0-line diff), so reusing the root node_modules is a clean control; among non-test sources only packages/core/src/index.ts (+1 barrel export, consumed by same-file.ts, never by the guard) and the guard itself change. Base arm = guard at HEAD^1 bundled standalone with esbuild, workspace imports aliased to the base tree's own sources; nine absence greps confirm the base bundle contains no PR machinery (preserveWindowsPathSeparators, containsCmdRewriteSyntax, containsUnmodelledWindowsSyntax, WIN32_PATH_RELINKING_PROGRAMS, splitFusedWindowsChdirs, doskey, setx, robocopy, POWERSHELL_ENV_MUTATION — all 0 hits). Head arm = the pre-built packages/cli/dist/src/serve/daemon-git-worktree-guard.js; readlink -f node_modules/@qwen-code/{qwen-code-core,acp-bridge} resolves into the head tree for both arms. Lane spoof mirrors the committed harness (process.platform + os.platform patch + MSYSTEM/TERM/ComSpec control); lane premises are additionally proven by the committed win32-lane suite's premise test inside the gate run.
A/B 1 — POSIX byte-identity (load-bearing for "no Linux/macOS regression")
Both compiled guards driven over an 84-command corpus covering the documented classes: relocated-mutating denials (-C, -C<value>, --git-dir/--work-tree, status --porcelain, grep --textconv), relocated read-only allows (rev-parse, cat-file), inside-boundary mutations incl. GIT_DIR=<in-boundary>/.git, non-git commands, POSIX wrappers (bash/sh/zsh/dash -c, bash -lc, env --chdir/-C), env-var relocations (GIT_DIR, GIT_WORK_TREE, GIT_CONFIG_GLOBAL), dynamic relocations ($VAR, $(…), backticks, ~, brace expansion), quoting variants incl. a POSIX backslash escape, alias/function shadow replay, the heredoc-body observation shape, eval (plain/quoted/dynamic), sudo -D/--chdir/plain, timeout, cd chains (&&, ;, .., pushd), subshells/pipes/separators, redirects/globs, the unrecognized-program backstop (su -c, nice), and section W: the 11 R7 cmd/powershell/pwsh shapes.
| cell | oracle | result |
|---|---|---|
| head arm, 84 commands | (allowed, reason) per command |
42 allowed / 42 denied |
| base arm, same corpus & fixtures | same | 42 allowed / 42 denied |

Section-W stances (head == base in every case): benign pwsh/cmd /c dir/powershell/powershell.exe/echo cmd powershell pwsh shapes allowed; git-shaped payloads inside unrecognized interpreters (pwsh -Command 'git -C <out> …', cmd /c "git -C <out> …", bash -c 'cmd /c "…"') denied by the base's pre-existing unrecognized-program rule, which head keeps.

A/B 2 — win32/cmd + win32/powershell + win32/gitbash lanes via the lane spoof
63 lane-tagged cells; 115 assertions; 33 base-allow → head-deny flips (the 16 documented shapes from the previous round plus 17 new-delta flips).
| arm | observable | result |
|---|---|---|
| attack cells: head deny (+ reason family where pinned) + base allow | 33 cells × 2–3 checks | all green |
| benign cells on head (both arms where pinned) | allowed | 8/8 |
| cross-lane identity cells (head==base) | (allowed, reason) identical |
7/7 |
| reason-supersede cells | both deny; families move as designed | 4/4 |
| total | 115/115 |
New-delta flips reproduced this round (each base ALLOW → head DENY on the cmd lane unless noted):
| id | shape | head reason |
|---|---|---|
| N1 | set GIT_WORK_TREE=<out>&& git reset --hard (probe-verified bypass, commit 15) |
outside boundary, names the path |
| N3/N4 | setx GIT_WORK_TREE <out|in> && git reset --hard |
dynamic repository location (in-boundary setx also fails closed — by design "can only add denials") |
| N7 | set /p X=&& git reset --hard |
dynamic repository location |
| N9/N10 | chdir <out> && git reset --hard, chdir /D <out> && … (probe-verified bypass, commit 15) |
outside boundary, names the path |
| N11 | path <out> && git reset --hard |
dynamic repository location |
| N12 | doskey git=evil.exe $* && git reset --hard |
unrecognized program |
| N15–N18 | fused climbs cd.. / chdir.. / pushd.. and cd/d <out> |
outside boundary |
| N22/N23/N25/N26 | case-folded keys: set git_work_tree=, set Git_Work_Tree=, set git_exec_path=, set path= |
outside / dynamic |
| N27 (ps lane) | set FOO=1; git status — PS set is Set-Variable |
dynamic (fail-closed by design) |
Cross-lane specificity held: on the Git Bash lane the identical set GIT_WORK_TREE=<out>&& git reset --hard is byte-identical in both arms (X7) — the builtin machinery stays off bash lanes; PS-lane caret/%…% cells identical in both arms (X1/X2). Reason-supersede cells (S1–S4) deny on both arms with the by-design family moves (unrecognized → undecidable for nested shells, unresolvable → cmd.exe rewrite syntax for %OUT%). mv/cp -r relink cells deny on BOTH arms (N19/N20) — POSIX relinks unaffected.

Adversarial sibling sweep on the delta machinery
36 cells probing adjacent shapes the committed tests do not pin (case-insensitive builtin names, fused flags, quoted set, expansion siblings, unmodelled control flow carrying git, fused nested shells, PowerShell env-mutation siblings, relink flag variants, benign no-regression shapes). Result: 26 pass / 7 fail — the 7 failures are Findings 1 and 2. Notably green: SET/SeT/SETX/CHDIR/PATH/DOSKEY case variants all denied; set "GIT_WORK_TREE=<out>" quoted-set denied; call/if exist/start/for /f carrying relocated git all denied; fused cmd/c with malign payload denied while benign cmd/c dir stays allowed; $env: mutation and echo $env:PATH read behave as documented; mklink /D, mklink /J, move, xcopy /E relinks denied; spaced set /p X= < file fails closed (the control that isolates Finding 1 to the fused spelling).

Config gating matrix (secondary claim, re-measured)
The three real config files transpiled with esbuild (only vitest/config stubbed to identity), judged in subprocesses under patched platform/CI:
| config | platform | CI | dangerouslyIgnoreUnhandledErrors |
coverage.enabled |
poolOptions |
|---|---|---|---|---|---|
| cli, core | linux | on/off | false | true | absent |
| cli, core | win32 | on | true | false | absent |
| cli, core | win32 | off | true | true (local keeps coverage) | absent |
| scripts | linux | on/off | false | (no gate) | absent (8–16 floor removed) |
| scripts | win32 | on/off | true | (no gate) | absent |
| scripts | win32 / linux | — | workflow-suite exclude glob present / absent | — | — |
36/36 head assertions pass; liveness control: the identical judge over the BASE configs differs on exactly the 18 changed cells (12 dangerouslyIgnoreUnhandledErrors, 2 win32-CI coverage, 4 scripts poolOptions) and matches everywhere else — the matrix is not vacuously green. 88/88 total. Capture: 05-config-gating-matrix.png. Raw: harness/config-matrix-rows.json.

Findings
1. High (new) — fused set/p (and set/<flag> spellings) bypass the win32 set arm; a stdin-redirect chain relocates a mutating git outside the boundary
Reproduce (harness cell, win32/cmd lane spoof; full transcript in harness/siblings-rows.json):
echo <outside> > src.txt && set/p GIT_WORK_TREE=x < src.txt && git reset --hard → head ALLOWS
set/p GIT_WORK_TREE=x < src.txt && git reset --hard → head ALLOWS
set /p GIT_WORK_TREE=x < src.txt && git reset --hard → head DENIES (control)
cmd.exe accepts builtin flags fused onto the word (set/p == set /p, same class as the cd/d forms this PR explicitly models in FUSED_CHDIR_PATTERN and pins in tests). executableBaseName('set/p') returns p, so the win32 set/setx arm never sees the token; it falls through as an unrecognized program, and the chained git reset --hard is judged cwd-local. Real cmd reads the value from the redirected stdin, so the executed chain runs git reset --hard under GIT_WORK_TREE=<outside> — exactly the relocation the guard exists to deny. Base allows the same shapes too (no Windows modelling at all), but the gap sits inside machinery this PR adds and documents as a closed enumeration ("cmd's state-persisting builtins are a closed set, so this enumerates them"). Blast radius: the fused spelling of any set flag (/p is the weaponizable one; /a fused would also route around the arm but is harmless) on any win32 non-bash lane.
Measured candidate fix
In analyzeRun, ahead of the set/setx arm:
if (
platform === 'win32' &&
getShellConfiguration().shell !== 'bash' &&
!token.dynamic &&
/^setx?\//i.test(token.text)
) {
// cmd fuses builtin flags onto the word (`set/p`, `set/a`), which
// executableBaseName reads as program `p`/`a` — the spaced-form scan
// below never runs. Which flag fused is not provable from the text
// and `/p` reads its value from stdin, so fail closed.
state.unresolved = true;
return { kind: 'export', state, operands: [] };
}Measured (scratch build, 06-fix-verification.png): all three hostile cells flip allow→deny; 175 corpus cells (84 POSIX + 63 win32 + 28 benign/other sibling cells) byte-identical to the shipped head; guard suites 889 passed | 53 skipped — green on both sides, i.e. the suite pins nothing along this axis; the fixture to write is a spoofed-win32-cmd expectation that set/p GIT_WORK_TREE=x < src.txt && git reset --hard denies (and its spaced twin).
2. High (new) — PowerShell Env: provider cmdlets mutate the process environment past POWERSHELL_ENV_MUTATION_PATTERNS
Reproduce (win32/powershell lane spoof):
Set-Item Env:GIT_WORK_TREE -Value <outside>; git reset --hard → head ALLOWS
Set-Item Env:GIT_WORK_TREE <outside>; git reset --hard → head ALLOWS
New-Item Env:GIT_WORK_TREE -Value <outside>; git reset --hard → head ALLOWS
set-item env:GIT_WORK_TREE <outside>; git reset --hard → head ALLOWS
$env:GIT_WORK_TREE = '<outside>'; git reset --hard → head DENIES (control)
Set-Item Env:NAME value writes the same process environment $env:NAME = value does — a later native git child inherits it — but the pattern set the PR added for exactly this hazard ($env: assignment, [Environment]::SetEnvironmentVariable) does not name the provider cmdlets, and the shape carries no paren/quote/& for the unmodelled-syntax gate to catch. Same blast radius as Finding 1 on the PowerShell lane; base allows it too (pre-existing absence), but the PR's own comment claims the enumeration ("PowerShell mutates the process environment through spellings no POSIX assignment scan reads"), so the sibling belongs in the sweep.
Measured candidate fix
Add to POWERSHELL_ENV_MUTATION_PATTERNS:
/^(?:set-item|new-item|clear-item|remove-item)\b[^;&|]*\benv:/i,Measured: all four hostile cells flip allow→deny; 175 corpus cells byte-identical; suites green both sides (fixtures to write: the four spellings above on a spoofed powershell lane). Residual siblings the measured patch still allows (verified): Copy-Item Env:FOO Env:GIT_WORK_TREE and Move-Item Env:FOO Env:GIT_WORK_TREE — also mutations; extend the alternation with copy-item|move-item|rename-item when implementing.
3. Suggestion (carried from round 3, stands) — the win32 keyword-form shadow hazard remains unpinned by the suite
Re-measured live. Mutation matrix at this head (two committed guard suites, in-place mutation with sha256 restore discipline; pristine 1a02685f… restored after every row, final tree verified clean):
| mutant | expected | result this round |
|---|---|---|
| CONTROL (unmutated) | green | 889 passed | 53 skipped, 0 failed |
| M5 R1-1 regression (escape char AFTER backslash) | killed | KILLED, 20 red |
| M7 alias gate (shadows recorded on win32 lanes) | killed | KILLED, 2 red (denies the divergent shape 10 alias cells) |
| M8 function-definition gate | survives | SURVIVED — 889 green |
| M9 set/setx arm dead | killed | KILLED, 7 red |
| M10 case-folding off | killed | KILLED, 2 red |
| M11 chdir out of cd family | killed | KILLED, 2 red |
M12 /MIR switch recorded |
killed | KILLED, 1 red — commit 21's lane-independent assertion is non-vacuous |
| M13 win32 relink set reduced to POSIX | survives | SURVIVED — see classification below |
| M14 fused-chdir split no-op | killed | KILLED, 2 red |
| COMBO all four shadow gates reverted | killed | KILLED, 2 red — the same two alias cells M7 pins |
C1 positive control (status added to relocated-read-only set) |
killed | KILLED, 5 red — suite liveness proven |
| PATCHED candidate fix (Findings 1+2) | green | 889 passed | 53 skipped — suite pins nothing along the bypass axis |
Consequence unchanged from the previous round: with all four gates reverted together, alias git='echo hi'; git -C <out> reset --hard and function git {…}; git -C <out> reset --hard become live bypasses on the win32 lanes, and the suite's only red cells are the alias shape — the keyword form is unpinned. M8 remains redundant defence (correct exactly as it stands; its sibling gates hold the hazard). Non-blocking; the fixture to write is a spoofed-win32-lane expectation that function git { echo hi; }; git -C <outside> reset --hard denies. Capture: 04-mutation-matrix-live.png. Reproduce: node harness/mutations.mjs.
M13 survivor classification (new): reverting WIN32_PATH_RELINKING_PROGRAMS to the POSIX set changed nothing because copy/mklink/move/robocopy/xcopy are unrecognized programs — the unrecognized-program backstop (relocation marker + git word in the same command) denies every committed relink shape before the relink recording is consulted (A/B 2 cells N13/N14 deny on BOTH arms, base included — the backstop dominates, the win32 relink state is never consulted for these programs). This is redundant defence, not a coverage gap: the behavior is pinned by another mechanism, and the recording becomes load-bearing only if one of these programs ever becomes a modelled program. Correct as shipped.
Vacuity and suite-liveness summary
- Committed guard suites at head (CONTROL row = targeted gate): 889 passed | 53 skipped (942), 0 failed — up from 838|53 at the previous head; the round-8..10 tests added 51 cases, and M9/M10/M11/M12/M14 prove the new delta machinery is pinned by them (kill counts above).
- Commit 21 (
/MIRlane-independent assertion): M12 reverts the switch-skip and turns exactly one test red — the newest commit's central test is non-vacuous; the assertion's lane-independence holds on this Linux host (posix spelling/MIR) with the win32 spelling (\MIR) covered by the regex in the spoofed-lane run. - Positive control C1 landed in the mutated file group (5 red).

Not covered
- Real Windows/macOS runners. This container is Linux; everything win32 ran through the committed lane spoof. Real
node:pathsemantics cannot be spoofed: shapes behinddescribe.runIf(real win32)are pinned only on the real lane, and backslash-path cells on this host resolve through POSIXpath.resolve(observed fail-closed as "unresolvable" where a backslash path cannot exist — correct on this host, not evidence about the real lane). - The
resolvePhysicalPathdrive-glue fix (C:\C:walk): unchanged since the previous round; still no Linux-executable runtime test (on POSIX both arms are identical becauseC:\…is not absolute). - Per-commit attribution: the metadata lists 21 commits; the depth-2 checkout leaves only the aggregate
HEAD^1..HEADdiff reachable (git rev-list HEAD^1..HEAD^2returns 1 at the shallow boundary — unreliable by definition;--is-shallow-repositorytrue). Round-by-round census numbers (69→5→0) and the revert/reapply pair (commits 16–17) were not individually exercised; note the aggregate diff contains the re-applied machinery intact (verified behaviorally by A/B 2 and the mutation matrix). isOwnerOnlyDirectorywin32 accept path (managed relocation re-enabled on Windows): win32-only code path, structurally inspected only; the POSIX leg is unchanged and exercised by the cli suite.- managed-scratch
ino === 0fail-closed branch andisSameFile's inode-unverifiable fallback: no ino-0 volume constructible on this fs; the fallback branch insame-file.tstherefore never fired in the probe (POSIX volume exposes real inodes — all 12 cases took the dev/ino leg, byte-identical to base). - The upstream vitest 60s birpc budget root cause — worked around, not fixed (declared out of scope by the PR).
- The PR's external CI evidence (verification run 32584463959, lanes green) — treated as an untested hypothesis; no token exists in this sandbox to inspect it.
- The fleet-shepherd root cause — bounded as load-correlated and pre-existing (Finding F2), not debugged further; out of this PR's scope.
- The previous round's 5-round flakiness gate was not re-run: substitutes this round were the full cli/core suites, the 13-row mutation matrix executed live repeatedly (final run in
04-mutation-matrix-live.png), and the both-arms scripts runs — all deterministic once contention was removed. - web-shell / sdk / integration-test suites: not run (untouched by this diff; typecheck covers compilation).
- cmd.exe
^/%VAR%usability remains fail-closed by design — a declared trade-off, confirmed enforced by the rewrite gate (A/B 2 cells D1/D2/S4). - Observation, pre-existing and byte-identical in both arms (not a PR finding; re-confirmed this round as corpus cell I2):
bash <<EOF\n<malignant>\nEOFis allowed — the heredoc-body strip models the body as non-argv stdin, which bash nonetheless executes. Flagging for maintainer awareness only. - No injection attempts were observed in the PR metadata (title/body/commit messages); none recorded.
Methodology
Environment: the CI verify container (node:22-bookworm, Node 22.23.2, vitest 3.2.7, 64 cores, CI=true, $RUNNER_TEMP = /__w/_temp for the runner expressions), working tree at refs/pull/9728/merge (merge commit 1cc0b86), npm ci + npm run build pre-run at HEAD. Head arm: pre-built packages/cli/dist/src/serve/daemon-git-worktree-guard.js. Base arm: git worktree add tmp/base-tree HEAD^1 (at 8be0715), guard compiled in isolation with esbuild, workspace imports aliased to the base tree's own sources (tmp/base-build/core-shim.ts), heavy runtime deps external (simple-git, @google/genai, fdir, iconv-lite; mime bundled after a mime/lite subpath-resolution failure); nine absence greps on the bundle; worktree removed after the last base cell. Lane spoof mirrors the committed harness. Harnesses in harness/ (common.mjs, ab-posix.mjs, ab-win32.mjs, siblings.mjs, config-matrix.mjs, issamefile.mjs, mutations.mjs, fix-verify.mjs) drive the real compiled guards/dists over mkdtemp fixture trees; denial reasons compared with fixture-suffix normalization where paths embed. Mutants applied in place with per-hunk exact-count checks and sha256 restore assertions (pristine 1a02685f… verified after every row and at the end); the PATCHED row ran the candidate fix through the same two suites. One harness-infrastructure note: an early full-file mutant used String.replace, whose $-pattern interpretation corrupted the source copy (visible as an esbuild "unterminated string" error); the driver was switched to split/join and the row re-run. Workspace gates ran with env -u QWEN_HOME (Finding 3) and --coverage.enabled=false; raw per-cell output in harness/*.json and per-suite logs in logs/. Evidence captures produced with scripts/verify-capture.mjs (evidence/*.png). assertions.json aggregates the seven harness tallies; the 7 failures are the sibling-sweep bypass cells (Findings 1–2); fix-verification assertions (183) measure the scratch candidate fix and are deliberately kept out of the verdict aggregate.

Round 11 disclosure: blockers only — deferred minor findings omitted per the convergence posture.
Scope — what I reviewed
Product code I read in full:

Not reviewed: 20 test-fixture files (POSIX-semantics corrections); the vitest CI harness beyond the changed config keys.
CI
Test (ubuntu-latest, Node 22.x): ✅ pass (26 min)Test (windows-latest, Node 22.x): ⏭ SKIPPED — merge_group-gated, no merge queue activeTest (macos-latest, Node 22.x): ⏭ SKIPPED — same reasonIntegration Tests (CLI, No Sandbox): ⏭ SKIPPED- Platform verification is via the author-linked workflow_dispatch run 32584463959, which is not an in-PR CI run.
Independent product-code findings: no blockers
isOwnerOnlyDirectory Win32 branch: return true is now gated after the isSymbolicLink() check. On NTFS (ino ≠ 0) the dev/ino TOCTOU checks that follow are effective; on FAT/exFAT (ino = 0) they pass trivially, acknowledged in the PR body as the same trade-off live/discovery.ts already accepts. managed-scratch-workspace.ts is deliberately stricter (rejects ino = 0 roots outright) — the asymmetry is intentional.
relinkProgramIndex rewrite: skipping only the single program-word token rather than every token whose name is a relink program name is correct — a destination spelled copy or xcopy was previously silently excluded from containment checks.
preserveWindowsPathSeparators → splitCommands ordering: the whole-command normalisation pass runs once before both splitCommands and readTopLevelSeparators, consistent with the comment that the two-stage view must agree on separator positions.
containsCmdRewriteSyntax and containsUnmodelledWindowsSyntax checked on strippedCommand before the backslash pre-pass: safe — neither function is sensitive to backslash escaping.
Cross-check against existing reviews
R3-3 — confirmed in code (dangerouslyIgnoreUnhandledErrors: process.platform !== 'linux' in packages/cli/vitest.config.ts:185, packages/core/vitest.config.ts:45, scripts/tests/vitest.config.ts:52 at this head). Effect: on macOS and Windows, a platform-specific unhandled rejection or teardown error after the last test completes is silently swallowed and the run exits 0. Coverage uses the CI-scoped form !process.env.CI || process.platform === 'linux'; the unhandled-error option uses only process.platform !== 'linux', so local macOS/Windows developer runs also suppress the signal — a wider scope than the CI-runner resource-pressure justification covers. Confirmed finding from prior reviewer; no new inline comment posted since the thread is already open.
R5-1 — cannot independently verify. The claim is that probe-verified divergences between the static analysis and actual cmd.exe / PowerShell execution remain at this head. I reviewed the guard logic in full and found no specific divergence I can confirm or refute without running Windows shells. I cannot clear this as a miss. Per review protocol, I am not approving while a Critical from another reviewer — backed by a stated execution witness and ten rounds of iteration — remains unresolvable from my side.
/MIR lane-dependence — fixed at this head. The assertion at win32-lane.test.ts:348 now reads expect.stringMatching(/[/\\\\]MIR/), covering both slash spellings. Finding from round 10 does not stand at bc304fd.

…C timeouts (QwenLM#10037) (QwenLM#10050) * fix(ci): yield the event loop between script tests to avoid vitest RPC timeouts (QwenLM#10037) The v0.22.1 release quality job exited 1 on `npm run test:scripts` with every test green. vitest's worker->main `onTaskUpdate` RPC has a fixed 60s timeout; the synchronous spawnSync-driven script suites keep a forked worker's event loop blocked for an entire file (~66s on the heaviest suite), so the queued RPC response is never processed before the timer fires, surfacing as an unhandled `[vitest-worker]: Timeout calling "onTaskUpdate"` error. Linux keeps unhandled errors fatal (the scripts vitest config only exempts non-Linux since QwenLM#9728), so the release died. Add a global per-test event-loop yield to the scripts test setup. The timer is captured at setup load so `vi.useFakeTimers()` inside a test cannot intercept the yield. Any continuous stall is now bounded by a single test, so RPC responses drain long before the 60s deadline. Real test failures stay fatal on every platform; the Linux unhandled-error signal is untouched. * fix(ci): state the actual yield invariant in the script test setup comment (QwenLM#10037) * test(ci): pin the script-test event-loop yield invariant (QwenLM#10037) --------- Co-authored-by: qwen-code-dev-bot <qwen-code-dev-bot@users.noreply.github.com> Co-authored-by: Shaojin Wen <shaojin.wensj@alibaba-inc.com>

Released in v0.22.2. |
…2-paths Resolve packages/cli/src/serve/daemon-git-worktree-guard.ts: main's QwenLM#9728 already landed an equivalent, broader fix for the same bug (preserveWindowsPathSeparators + containsCmdRewriteSyntax), so take main's implementation instead of layering this branch's placeholder masking on top of it. The branch's win32 test block is kept: every case still denies under main's implementation, so only the expected denial reasons were retuned. The design-doc paragraph is rewritten to describe the implementation that actually ships.

What this PR does
Repairs the test failures that turn the Windows and macOS CI lanes red, so the two platform lanes can be revived (#9370) without leaving
mainfailing. The failures split into a few product fixes, a batch of test-fixture repairs, and a CI-harness repair. The product fixes make the daemon's Git worktree guard understand Windows paths (two defects: the tokenizer consumed backslashes as POSIX escapes, and the physical-path walker glued the drive segment back onto the root), stop Live managed relocation from being hard-disabled on Windows, and stopisSameFilefrom equating distinct files on volumes that report no usable inode identity. The fixture repairs make tests stop assuming POSIX filesystem semantics — permission bits,ENOTDIR, in-place overwrite of git-managed files, forward-slash git output, JSON-escaped log matching,/tmpliterals, removable temp dirs while a backgrounded service still holds them, and inode-keyed caches on volumes without real inode identity — that Windows does not provide. The harness repair stops a deterministic vitest worker-RPC unhandled error from exiting all-green suites red on the Windows/macOS runners: those suites no longer treat unhandled errors as fatal (test failures stay fatal), and coverage reports — consumed only from the ubuntu lane — are skipped on non-Linux CI.Why it's needed
The macOS and Windows lanes have been dark since 2026-07-02: they were gated on
merge_group, and no merge queue is enabled on this repository, so they reported "skipped" on every pull request for six weeks. Code that breaks Windows therefore merged unobserved — including a hardening change that made a daemon guard unusable on Windows and a predicate that disables Live conversation relocation there entirely. #9370 gives the lanes a trigger again; its first run surfaced this backlog. Landing these fixes first means the revived lanes go green instead of leavingmainred until someone works through the fallout. The #9481 failure census (then 59 tests across 10 files, now 72 across 16 — the rot grows while unobserved) plus a new failure from the PR-binding feature that landed this morning are what this PR clears.Reviewer Test Plan
How to verify
The changes are test-infrastructure and a few narrow product paths; nothing user-visible changes on Linux.
Product behavior worth reading the diff for: the daemon shell guard gains a win32-only pre-pass that keeps unquoted backslashes intact before POSIX tokenisation, so
git -C C:\repo\sub …is analysed as an absolute relocation instead of a mangled relative word, and its physical-path walker no longer rejoins the Windows drive segment onto the root — on POSIX both are byte-identical behavior.isOwnerOnlyDirectoryno longer returns false for every directory on Windows; it falls back to the structural checks around it (symlink rejection, dev/ino identity across the realpath round trip), the same trade-offserve/live/discovery.tsalready makes on this platform, and keeps the POSIX mode/uid test unchanged.The CI evidence is the final verification run on
verify-win-fix(this branch merged with #9370's workflow so the revived lanes actually execute): https://github.com/QwenLM/qwen-code/actions/runs/32584463959 — the end of an iteration chain that started from a baseline of 69 Windows test failures plus a macOS lane that exits 1 with every test green (baseline run 32543605012, re-confirmed on current main by run 32565934292): round one's repairs cut the Windows failures from 69 to 5 (and surfaced a third product defect the first fix exposed), round two's repairs took the remaining 5 to zero and turned the macOS lane green, rounds three and four eliminated the deterministic all-green-exit-1 vitest RPC failure class on the package suites (round four's review also fixed the Critical finding that the win32 pre-pass could glue a flag into a relocation value), and round five cleared three more failures that recent main commits introduced while the lanes stayed dark (dev/ino file identity, a busy temp dir, an inode-keyed cache collision). Every touched test file also passes locally on macOS, and typecheck is clean for the cli, core, and acp-bridge packages.Evidence (Before & After)
N/A — CI infrastructure and test fixtures, no user-visible output. Before:
Test (windows-latest, Node 22.x)fails 69 tests across 13 files andTest (macos-latest, Node 22.x)exits 1 despite all tests passing. After: both lanes green on the verification run above.Tested on

isOwnerOnlyDirectoryrelaxation on Windows accepts the platform's weaker containment model (no POSIX mode bits exist to check) in exchange for the feature working at all — the same trade-off already accepted by Live discovery on Windows. The cli, core, and scripts suites now ignore unhandled errors (test failures stay fatal): this trades away their unhandled-rejection signal to stop a deterministic vitest worker-RPC timeout from exiting all-green runs red on the platform runners; every other suite keeps the stricter behavior.^escapes,%VAR%); commands using those forms remain fail-closed on Windows as today. The upstream root of the onTaskUpdate timeout (a stall past vitest's hardcoded 60s worker-RPC budget under runner resource pressure) is worked around, not fixed in vitest itself.Linked Issues

中文说明
这个 PR 做了什么
修复让 Windows 和 macOS CI lane 变红的测试失败，使两条平台 lane 可以被复活（#9370）而不会让
main处于失败状态。失败分为少量产品修复、一批测试夹具修复，以及一处 CI 脚手架修复。产品修复让 daemon 的 Git worktree guard 理解 Windows 路径（两处缺陷：分词器把反斜杠当 POSIX 转义吃掉；物理路径遍历把盘符段重新拼回根目录），停止在 Windows 上硬性禁用 Live 托管重定位，并阻止isSameFile在不提供可用 inode 身份的卷上把不同文件判为相同。夹具修复让测试不再假设 Windows 不具备的 POSIX 文件系统语义——权限位、ENOTDIR、对 git 管理文件的原地覆盖、正斜杠的 git 输出、JSON 转义后的日志匹配、/tmp字面量、后台服务仍占用目录时删除临时目录、以及在没有真实 inode 身份的卷上按 inode 建键的缓存。脚手架修复阻止一个确定性的 vitest worker RPC 未处理错误把全部测试通过的套件在 Windows/macOS runner 上 exit 1：这些套件不再把未处理错误判为致命（测试失败仍然致命），并且覆盖率报告——只被 ubuntu lane 消费——在非 Linux CI 上跳过。为什么需要
macOS 和 Windows lane 自 2026-07-02 起就是黑的：它们被门控在
merge_group上，而本仓库没有启用 merge queue，所以六周来每个 PR 上都显示 "skipped"。因此，会弄坏 Windows 的代码在无人观测的情况下合入了——包括一次让某个 daemon guard 在 Windows 上不可用的加固改动，以及一个在 Windows 上彻底禁用 Live 会话重定位的谓词。#9370 重新给了这两条 lane 触发器；它的第一次运行暴露了这笔欠账。先合入这些修复，复活后的 lane 就是绿的，而不是让main一直红着等谁去清理。#9481 的失败清点（当时 10 个文件 59 个测试，现在 16 个文件 72 个——无人观测时烂账还在增长），加上今晨合入的 PR 绑定功能引入的一个新失败，正是本 PR 清理的对象。审阅者测试计划
如何验证
改动是测试基础设施和几条狭窄的产品路径；Linux 上没有任何用户可见的变化。
值得读 diff 的产品行为：daemon shell guard 增加了一个仅 win32 生效的预处理，在 POSIX 分词之前保留未加引号的反斜杠，使
git -C C:\repo\sub …被分析为绝对路径重定位而不是被肢解的相对词；其物理路径遍历也不再把 Windows 盘符段重新拼回根目录——在 POSIX 上两者行为逐字节一致。isOwnerOnlyDirectory不再对 Windows 上的每个目录返回 false；它退回到其周围的结构性检查（拒绝符号链接、realpath 往返前后的 dev/ino 同一性），这与serve/live/discovery.ts在该平台上已接受的取舍相同，且 POSIX 的 mode/uid 检查保持不变。CI 证据是
verify-win-fix（本分支与 #9370 的工作流合并，使复活后的 lane 真正执行）上的最终验证运行：https://github.com/QwenLM/qwen-code/actions/runs/32584463959 ——这是一条迭代链的终点，起点是 69 个 Windows 测试失败、外加一条所有测试通过却 exit 1 的 macOS lane（基线运行 32543605012，并由运行 32565934292 在当前 main 上再次确认）：第一轮修复把 Windows 失败从 69 降到 5（并暴露出第一处修复牵出的第三个产品缺陷），第二轮修复把剩余 5 个清零并让 macOS lane 转绿，第三、四轮消除了包套件上"全部通过却 exit 1"的确定性 vitest RPC 故障类（第四轮的评审还修复了 win32 预处理可能把旗标粘进重定位值的 Critical 发现），第五轮清理了 lane 停摆期间新合入 main 的提交引入的另外三个失败（dev/ino 文件身份、被占用的临时目录、按 inode 建键的缓存冲突）。每个被改动的测试文件也在 macOS 本地通过，cli、core、acp-bridge 包的类型检查干净。证据（前后对比）
N/A——CI 基础设施与测试夹具，无用户可见输出。之前：
Test (windows-latest, Node 22.x)在 13 个文件中失败 69 个测试，Test (macos-latest, Node 22.x)在所有测试通过的情况下 exit 1。之后：上述验证运行中两条 lane 均为绿色。测试环境
环境（可选）
macOS 上的单元测试（对每个被改动的文件
npx vitest run）；Windows 与 macOS lane 通过在携带本修复与 #9370 工作流触发器的分支上对ci.yml执行workflow_dispatch运行，走仓库的自托管/托管 runner。风险与范围
isOwnerOnlyDirectory在 Windows 上的放宽接受该平台更弱的容器模型（没有 POSIX 权限位可查），换取功能整体可用——这与 Live discovery 在 Windows 上已接受的取舍相同。cli、core、scripts 三个套件现在忽略未处理错误（测试失败仍然致命）：用掉它们的未处理 rejection 信号，换取一个确定性的 vitest worker RPC 超时不再把全部通过的运行在平台 runner 上判为失败；其余套件保持更严格的行为。^转义、%VAR%）；使用这些形态的命令在 Windows 上与现状一致，仍然失败即关闭。onTaskUpdate 超时的上游根因（在 runner 资源压力下停顿超过 vitest 硬编码的 60 秒 worker RPC 预算）是绕过，不是在 vitest 本身修复。关联 Issue
