fix(cli): don't crash startup when the output-language file is unwritable (#10453) #10455

qwen-code-ci-bot · 2026-08-29T05:04:49Z

[Suggestion] R1-2: The new test pins the creation-path catch only via a mkdirSync failure; the creation-path writeFileSync failure shape has no test. In the exact environment this PR targets where ~/.qwen already exists (container/CI images often pre-create it), fs.mkdirSync(dir, { recursive: true }) succeeds on the existing dir and it is fs.writeFileSync that throws (EROFS/EACCES). The new catch handles that today, but a later change that narrows or relocates the try (e.g. wrapping only the mkdir) re-introduces the startup crash for that failure shape with the whole suite staying green. Mirror the migration-failure test for the creation path: existsSync → false, mkdirSync succeeding, fs.writeFileSync mocked to throw (e.g. new Error('EROFS: read-only file system')), then assert expect(() => initializeLlmOutputLanguage()).not.toThrow().

Witness:

Mutation matrix in scratch tree (npx vitest run src/i18n/languageUtils.test.ts): intact PR → Tests 59 passed (59) guard narrowed to mkdir only → Tests 59 passed (59) (regression invisible) mutation + suggested test added → × expected [Function] to not throw an error but 'Error: EROFS: read-only file system' was thrown PR restored + suggested test → Tests 60 passed (60)

The added test is its own acceptance criterion: removing the creation-path catch (or narrowing the try so writeFileSync sits outside it) must make it throw and fail the assertion — please confirm by deleting the guard and watching the new test go red.

中文说明

R1-2：新测试只通过 mkdirSync 失败来固定创建路径的 catch；创建路径上 writeFileSync 失败的形态没有测试覆盖。在本 PR 针对的确切环境中——~/.qwen 已存在（容器/CI 镜像通常会预先创建它）——fs.mkdirSync(dir, { recursive: true }) 对已存在目录会成功，抛出异常（EROFS/EACCES）的是 fs.writeFileSync。新加的 catch 目前能处理这种情况，但后续任何收窄或移动该 try 的改动（例如只包住 mkdir）都会让这种失败形态重新引发启动崩溃，而整个测试套件依然全绿。建议为创建路径补一个与迁移失败测试对称的用例：existsSync → false、mkdirSync 成功、fs.writeFileSync 被 mock 为抛异常（例如 new Error('EROFS: read-only file system')），然后断言 expect(() => initializeLlmOutputLanguage()).not.toThrow()。

见证：

在 scratch tree 中运行变异矩阵（npx vitest run src/i18n/languageUtils.test.ts）：完整 PR → Tests 59 passed (59) 守卫收窄为仅包 mkdir → Tests 59 passed (59) （回归不可见）变异 + 补上建议的测试 → × expected [Function] to not throw an error but 'Error: EROFS: read-only file system' was thrown 恢复 PR + 建议的测试 → Tests 60 passed (60)

新增测试本身就是验收标准：移除创建路径的 catch（或收窄 try 使 writeFileSync 位于其外）必须让它抛异常并使断言失败——请通过删除守卫并观察新测试变红来确认。

[Suggestion] R1-2: The new test pins the creation-path catch only via a mkdirSync failure; the creation-path writeFileSync failure shape has no test. Still stands this round — the code here is unchanged since round 1.

In the exact environment this PR targets where ~/.qwen already exists (container/CI images often pre-create it), fs.mkdirSync(dir, { recursive: true }) succeeds on the existing dir and it is fs.writeFileSync that throws (EROFS/EACCES). The new catch handles that today, but a later change that narrows or relocates the try (e.g. wrapping only the mkdir) re-introduces the startup crash for that failure shape with the whole suite staying green. Mirror the migration-failure test for the creation path:

it('should not throw when the rule file cannot be created (write failure)', () => { vi.mocked(fs.existsSync).mockReturnValue(false); vi.mocked(fs.writeFileSync).mockImplementation(() => { throw new Error('EROFS: read-only file system'); }); expect(() => initializeLlmOutputLanguage()).not.toThrow(); });

Witness:

Mutation matrix in scratch tree (npx vitest run src/i18n/languageUtils.test.ts): intact PR -> Tests 59 passed (59) guard narrowed to mkdir only -> Tests 59 passed (59) (regression invisible) mutation + suggested test added -> x expected [Function] to not throw an error but 'Error: EROFS: read-only file system' was thrown PR restored + suggested test -> Tests 60 passed (60)

The added test is its own acceptance criterion: removing the creation-path catch (or narrowing the try so writeFileSync sits outside it) must make it throw and fail the assertion — please confirm by deleting the guard and watching the new test go red.

[Critical] R1-1: [certifies-falsely] [new-surface] Fixes #10453 will auto-close the per-commit tracking issue for an unexplained main-CI failure that this diff demonstrably does not change. Issue #10453 tracks exactly one thing: "A main-branch CI run failed on main before any test result was reported, so this issue is tracked per commit" (run 33228441400). This diff touches only the startup language-file write; the run's pre-test steps (docker lane, npm, build, bundle) are untouched, and on hosts with a writable HOME the new try/catch never fires, so the run completes exactly as before. The PR's own E2E report concedes as much: "neither alone explains run 33228441400's 'no test results reported' signature. The most probable cause of that run remains a pre-test step." On merge, the closing keyword archives the actually-observed red run as "fixed" while its cause remains unknown, and the autofix claim protocol — "If the attempt fails, this claim will be withdrawn so a human can take over" — is bypassed: no human inherits the unexplained run. There is also no follow-up issue owning the escalated extension-store crash site. Suggested resolution: remove the closing keyword (reference the issue non-closing, e.g. "Part of the investigation of #10453"), leave #10453 open or obtain an explicit maintainer ruling to close it with the non-attribution documented, and file a follow-up issue for the escalated crash site. The guard and its test are correct and should stay as-is.

Witness:

gh pr view 10455 --json body → "## Linked Issues / Fixes #10453" gh issue view 10453 → state OPEN, "A main-branch CI run failed on `main` before any test result was reported, so this issue is tracked per commit" (run 33228441400) PR comment 5460155764 → "neither alone explains run 33228441400's 'no test results reported' signature" diff = languageUtils.ts + test only gh search issues "prepareDirectories" → [] (no follow-up issue owns crash site 2)

The fix rests on the autofix claim protocol's own premise: "If the attempt fails, this claim will be withdrawn so a human can take over." (claim comment on issue #10453) — closing the issue via a PR that does not reach the tracked failure silently drops that human handover.

中文说明

R1-1：Fixes #10453 会自动关闭一个按提交跟踪"主分支 CI 无法解释的失败"的 issue，而本 diff 已被证明不会改变该失败的任何环节。issue #10453 跟踪的恰好是一件事："主分支的一次 CI 运行在任何测试结果上报之前失败，因此按提交跟踪此问题"（运行 33228441400）。本 diff 只触及启动期语言文件写入；该运行的测试前步骤（docker 通道、npm、构建、打包）均未改动，且在 HOME 可写的主机上新加的 try/catch 根本不会触发，运行结果与之前完全相同。本 PR 自己的 E2E 报告也承认："两者都无法单独解释运行 33228441400 的'没有任何测试结果上报'特征。该次运行最可能的原因仍是测试前的步骤。"合并后，关闭关键字会把实际观察到的红色运行归档为"已修复"，而其原因仍然未知，autofix 认领协议——"如果尝试失败，该认领将被撤回，以便人类接管"——被绕过：没有人接手这次无法解释的运行。此外也没有任何后续 issue 承接被升级上报的扩展存储崩溃点。建议处理方式：移除关闭关键字（改为非关闭引用，例如"属于 #10453 调查的一部分"），让 #10453 保持打开，或取得维护者的明确裁决并在记录非归因的前提下关闭，同时为升级上报的崩溃点建立后续 issue。守卫本身及其测试是正确的，应原样保留。

见证：

gh pr view 10455 --json body → "## Linked Issues / Fixes #10453" gh issue view 10453 → state OPEN, "A main-branch CI run failed on `main` before any test result was reported, so this issue is tracked per commit"（运行 33228441400） PR 评论 5460155764 → "neither alone explains run 33228441400's 'no test results reported' signature" diff = 仅 languageUtils.ts + 测试 gh search issues "prepareDirectories" → []（没有后续 issue 承接崩溃点 2）

该修复依赖 autofix 认领协议自身的前提："如果尝试失败，该认领将被撤回，以便人类接管。"（issue #10453 上的认领评论）——通过一个并未触及被跟踪失败的 PR 来关闭该 issue，会悄悄丢弃这一人类接管机制。

[Critical] R1-1: [certifies-falsely] [new-surface] Fixes #10453 attributes to this diff a main-CI failure that this diff demonstrably does not change. Still stands this round, re-checked against the live PR state. Issue #10453 tracked exactly one thing: main-CI run 33228441400, which failed on main before any test result was reported. This diff touches only the startup language-file write; the run's pre-test steps (docker lane, npm, build, bundle) are untouched, and on hosts with a writable HOME the new try/catch never fires — so no step of the tracked failure is altered by any line of this diff. The PR's own Risk & Scope concedes "The exact cause of the original CI run 33228441400 could not be confirmed from this environment ... no change to CI machinery is made", and the E2E report concedes neither crash the diff fixes explains the run's "no test results reported" signature. On merge, project history records this PR as the resolution of run 33228441400 while its cause stays undiagnosed, and the failure family provably continues — successor tracking issues 10473/10475/10476/10478/10482/10487 are all OPEN. The autofix claim protocol's promised human handover — "If the attempt fails, this claim will be withdrawn so a human can take over" — was never honored: the claim was never withdrawn (label autofix/in-progress still attached) and the issue's close (2026-08-29T06:43:13Z) carries no recorded rationale. Suggested resolution: remove the closing keyword (reference the issue non-closing, e.g. "Part of the investigation of #10453"), or obtain an explicit maintainer ruling and document the non-attribution in the Linked Issues section (the concession already exists in Risk & Scope and currently contradicts the Fixes line in the same body); optionally promote the escalated ExtensionStore.prepareDirectories crash site recorded in issue 10511 into its own follow-up issue. The guard and its test are correct and should stay as-is.

Witness:

gh pr view 10455 body lines 39/82 -> "Fixes #10453" (verified live this round) gh issue view 10453 -> CLOSED 2026-08-29T06:43:13Z, close carries no rationale, label autofix/in-progress still attached successor main-CI tracking issues 10473/10475/10476/10478/10482/10487 -> all OPEN diff -> packages/cli/src/i18n/languageUtils.{ts,test.ts} only; pre-test steps untouched

The fix must not violate the autofix claim protocol on issue #10453 (claim comment by qwen-code-dev-bot): "If the attempt fails, this claim will be withdrawn so a human can take over." — the resolution must preserve a documented human handover; the issue's close carries no recorded rationale.

[Critical] R1-1: [certifies-falsely] [new-surface] Fixes #10453 attributes to this diff a main-CI failure that this diff demonstrably does not change. Still stands this round, re-checked against the live PR state and the code at the reviewed commit.

Issue #10453 tracked exactly one thing: main-CI run 33228441400, which failed on main before any test result was reported. Replaying that run against the post-change workflow: the pre-test steps that failed (docker lane, npm, build, bundle) are untouched by this diff — the diff is only the startup language-file guard and its test — and on hosts with a writable HOME the new try/catch never fires, so every step of the tracked run completes exactly as before. On merge, project history records this PR as the resolution of run 33228441400 while its cause stays undiagnosed. The failure family provably continues: successor tracking issue #10473 shows the identical "no test results reported" signature recurring, and the autofix claim there was withdrawn. The claim protocol's promised human handover — "If the attempt fails, this claim will be withdrawn so a human can take over" — was never honored for #10453: the issue was closed manually (yiliang114, 2026-08-29T06:43:14Z) with no withdrawal comment, no rationale, and the autofix/in-progress label still attached. The PR's own Risk & Scope concedes the run's cause "could not be confirmed from this environment" and that "no change to CI machinery is made" — which contradicts the Fixes line in the same body. The guard and its test are correct and should stay as-is; the defect is the closing attribution.

Re-checked against the live PR state and the run's own job logs this round — still stands. Issue #10453 tracked exactly one thing: main-CI run 33228441400, which failed on main before any test result was reported. Replaying that run against the post-change workflow: the diff (+15/−1, languageUtils.{ts,test.ts} only) touches no CI machinery; on hosts with a writable HOME the new try/catch never fires, so every step of the tracked run completes exactly as before; on unwritable-HOME hosts the PR's own Risk & Scope concedes the lane still stops at the out-of-scope second crash site (ExtensionStore.prepareDirectories). The run's retrieved job log shows its actual reported failure was cli/qwen-serve-routes.test.ts > advertises all baseline capabilities (- "native_directory_picker", macOS shard 2/2) — nothing in this diff touches that test or its data. On merge, project history records this PR as the resolution of run 33228441400 while its cause stays undiagnosed; the failure family provably continues — successor tracking issue #10473 (identical "no test results reported" signature) is OPEN; and the autofix claim protocol's promised human handover was never honored: the claim was never withdrawn (label autofix/in-progress still attached) and the issue's manual close (2026-08-29, by yiliang114) carries no recorded rationale. The PR body contradicts itself: Risk & Scope says "The exact cause of the original CI run 33228441400 could not be confirmed from this environment ... no change to CI machinery is made" while Linked Issues says Fixes #10453. Suggested resolution: remove the closing keyword and reference the issue non-closing (e.g. "Part of the investigation of #10453") in both language sections, or obtain an explicit maintainer ruling and document the non-attribution in Linked Issues; optionally reopen #10453 or document why it was closed without a claim withdrawal, and promote the escalated ExtensionStore.prepareDirectories crash site into its own follow-up issue.

[Critical] R1-1: [certifies-falsely] [new-surface] Fixes #10453 attributes to this diff an unexplained main-CI failure that this diff demonstrably does not change. Still stands this round, re-verified against the live PR state and the tracked run's own job data.

Issue #10453 tracked exactly one thing: main-CI run 33228441400. This round the run's job data was retrievable: its only failing job was E2E Test - macOS - shard 2/2 (job 99036635251) on a GitHub-hosted runner — Checkout/Install/Build/Bundle all succeeded, Run E2E tests failed — while all six Linux sandbox:none/docker shards passed. The crash this PR guards requires an unwritable global config dir; on a hosted runner HOME is writable, so the new try/catch never fires there. The diff (+15/−1, languageUtils.{ts,test.ts} only) touches no CI machinery, so no step of the tracked run changes outcome under any hypothesis — yet on merge the closing keyword records this PR as the resolution of run 33228441400 while its cause stays undiagnosed. The PR body contradicts itself: Risk & Scope says "The exact cause of the original CI run 33228441400 could not be confirmed from this environment ... no change to CI machinery is made" while Linked Issues says Fixes #10453. The failure family provably continues — successor tracking issues carry the identical signature for later main commits — and the autofix claim protocol's promised human handover ("If the attempt fails, this claim will be withdrawn so a human can take over") was never honored: #10453 was closed manually (yiliang114, 2026-08-29T06:43:14Z) with no rationale, no claim withdrawal, and the autofix/in-progress label still attached. The guard and its test are correct and should stay as-is; the defect is the closing attribution.

Remove the closing keyword in both language sections and reference the issue non-closing (e.g. "Part of the investigation of #10453"), moving the non-attribution concession already present in Risk & Scope into Linked Issues so the body no longer contradicts itself — or obtain an explicit maintainer ruling and document the non-attribution there. Reopen #10453 or record why it was closed without a claim withdrawal; optionally promote the escalated ExtensionStore.prepareDirectories crash site into its own follow-up issue.

The fix must not violate the autofix claim protocol on issue #10453 (claim comment by qwen-code-dev-bot, 2026-08-29T02:36:03Z): "If the attempt fails, this claim will be withdrawn so a human can take over." — the resolution must preserve a documented human handover for the undiagnosed run; the issue's manual close carries no recorded rationale.

[Critical] R1-1：[certifies-falsely] [new-surface] Fixes #10453 把一个本 diff 已被证明无法改变的主分支 CI 无法解释失败归因于本 PR。本轮按 PR 实时状态与被跟踪运行自身的任务数据复查——仍然成立。

issue #10453 跟踪的恰好是一件事：主分支 CI 运行 33228441400。本轮成功取回了该运行的任务数据：其唯一失败的任务是 E2E Test - macOS - shard 2/2（任务 99036635251），运行在 GitHub 托管 runner 上——Checkout/Install/Build/Bundle 全部成功，Run E2E tests 失败——而全部六个 Linux sandbox:none/docker 分片均通过。本 PR 守卫的崩溃需要全局配置目录不可写；托管 runner 的 HOME 可写，因此新加的 try/catch 在那里根本不会触发。本 diff（+15/−1，仅 languageUtils.{ts,test.ts}）未触及任何 CI 机制，因此在任何假设下，被跟踪运行的任何一个环节的结果都不会改变——但合并后关闭关键字会把本 PR 记录为运行 33228441400 的解决方式，而其原因仍未诊断。PR 描述自相矛盾：Risk & Scope 写着"原始 CI 运行 33228441400 的确切原因无法从本环境确认……本 PR 不对 CI 机制做任何改动"，而 Linked Issues 却写着 Fixes #10453。失败家族被证明仍在持续——后续跟踪 issue 在更晚的 main 提交上带有完全相同的特征——而 autofix 认领协议承诺的人类交接（"如果尝试失败，该认领将被撤回，以便人类接管"）始终没有兑现：#10453 被人工关闭（yiliang114，2026-08-29T06:43:14Z），没有任何理由、没有撤回认领，autofix/in-progress 标签仍然挂着。守卫本身及其测试是正确的，应原样保留；缺陷在于关闭归因。

请在两个语言部分移除关闭关键字，改为非关闭引用（例如"属于 #10453 调查的一部分"），把已存在于 Risk & Scope 的非归因让步移到 Linked Issues 部分，使描述不再自相矛盾——或取得维护者的明确裁决并在该处记录非归因。重新打开 #10453，或记录其在没有撤回认领的情况下被关闭的原因；可选地将升级上报的 ExtensionStore.prepareDirectories 崩溃点转为独立的后续 issue。

处理方式不得违反 issue #10453 上的 autofix 认领协议（qwen-code-dev-bot 于 2026-08-29T02:36:03Z 的认领评论）："如果尝试失败，该认领将被撤回，以便人类接管。"——处理方式必须为这次未诊断的运行保留书面的人类交接；该 issue 的人工关闭没有任何已记录的理由。

[Critical] R1-1: [certifies-falsely] [new-surface] Fixes #10453 attributes to this diff an unexplained main-CI failure that this diff demonstrably does not change. Re-checked against the live PR state and the code at the reviewed commit — still stands.

Issue #10453 tracked exactly one thing: main-CI run 33228441400, which failed on main before any test result was reported. Replaying that run against the post-change workflow: this diff touches only the startup language-file write and its unit test; every pre-test step of the tracked run (docker lane, npm, build, bundle) is untouched, and on hosts with a writable HOME the new try/catch never fires — so no step of the tracked failure changes outcome. Even on the author's unwritable-HOME repro host, this PR's own Test Plan concedes the lane still stops at a second, separate unwritable-dir site in the extension store. On merge, project history records this PR as the resolution of run 33228441400 while its cause stays undiagnosed, and the failure family demonstrably continues — successor issue #10473 recurred with the identical signature and was closed with autofix/skip. The guard itself and its test are correct and should stay as-is; the defect is solely the closing attribution. The PR body contradicts itself: Risk & Scope says the run's cause "could not be confirmed from this environment" and "no change to CI machinery is made", while the Linked Issues section of the same body says Fixes #10453.

Suggested resolution: remove the closing keyword and reference the issue non-closing (e.g. "Part of the investigation of #10453") in both body sections, or obtain an explicit maintainer ruling and document the non-attribution in Linked Issues (the concession already exists in Risk & Scope). Reopen #10453 or record why it was closed with the autofix/in-progress label still attached, no withdrawal comment, and no rationale; optionally promote the escalated ExtensionStore.prepareDirectories crash site into its own follow-up issue, since even the author's repro lane stays red until it is addressed.

Witness:

gh pr view 10455 --json body -> 39:Fixes #10453 / 82:Fixes #10453 (both language sections, live this round) gh issue view 10453 -> CLOSED, labels incl. autofix/in-progress, body tracks run 33228441400 "before any test result was reported" timeline -> {"actor":"yiliang114","commit_id":null,"event":"closed"} — manual close, no rationale; the claim comment is the issue's only comment PR E2E report -> "neither alone explains run 33228441400's 'no test results reported' signature" successor #10473 -> identical signature, CLOSED with autofix/skip

The fix must not violate the autofix claim protocol on issue #10453 (claim comment by qwen-code-dev-bot, 2026-08-29T02:36:03Z): "If the attempt fails, this claim will be withdrawn so a human can take over." — any resolution must preserve a documented human handover for the unexplained run; the existing close carries no recorded rationale.

[Critical] R1-1: [certifies-falsely] [new-surface] Fixes #10453 attributes to this diff a main-CI failure that this diff demonstrably did not cause and does not change. Re-checked this round against the live PR state — still stands.

Issue #10453 tracked exactly one thing: main-CI run 33228441400, which failed on main before any test result was reported. That run's job log shows its only failure was cli/qwen-serve-routes.test.ts > advertises all baseline capabilities (- "native_directory_picker", macOS shard 2/2), fixed on main by 03a9fb72e2 (#10456) — a different commit that is already an ancestor of this PR's head. The PR's named repro cli/qwen-config-dir.test.ts was GREEN in that same job. This diff touches only the startup language-file write, so replaying the tracked run against the post-change code changes no step's outcome under any hypothesis. On merge, the closing keyword archives the observed red run as resolved by a diff the run's own log proves unrelated, so the recorded cause stays wrong in project history and the commit that actually fixed it goes uncredited. The PR body contradicts itself: Risk & Scope says "The exact cause of the original CI run 33228441400 could not be confirmed from this environment ... no change to CI machinery is made" while both language sections still say Fixes #10453 (verified live this round). The autofix claim protocol's promised human handover never happened either: #10453 was closed manually with no withdrawal, no rationale, and the autofix/in-progress label still attached.

What is NOT being asked: the guard and its test are correct and should stay exactly as they are — this finding is about the closing attribution only. Human review (comment 5482828147) verified the code clean and left this finding's disposition as a maintainer decision; previous rounds' land-with-residual-risk recommendation stands.

Suggested resolution: drop the closing keyword in both language sections and reference the issue non-closing (e.g. "Part of the investigation of #10453"), or obtain an explicit maintainer ruling and document the non-attribution in Linked Issues. The escalated second crash site is tracked in #10511.

issue #10453 跟踪的恰好是一件事：主分支 CI 运行 33228441400，在任何测试结果上报之前失败。该次运行的任务日志显示其唯一失败是 cli/qwen-serve-routes.test.ts > advertises all baseline capabilities（- "native_directory_picker"，macOS 分片 2/2），已由 03a9fb72e2（#10456）在 main 上修复——那是另一个提交，且已是本 PR head 的祖先。本 PR 自述的复现用例 cli/qwen-config-dir.test.ts 在同一任务中是绿色的。本 diff 只触及启动期语言文件写入，因此用变更后的代码回放被跟踪的运行，在任何假设下都不会改变任何一个环节的结果。合并后，关闭关键字会把一次实际观察到的红色运行归档为"由本 diff 解决"，而该运行自身的日志证明两者无关——项目历史中的原因记录因此是错的，真正修复它的提交也得不到归属。PR 描述自相矛盾：风险与范围部分写着"原始 CI 运行 33228441400 的确切原因无法从本环境确认……本 PR 不对 CI 机制做任何改动"，而两个语言部分至今仍写着 Fixes #10453（本轮实时核实）。autofix 认领协议承诺的人类交接也从未兑现：#10453 被人工关闭，没有撤回、没有理由，autofix/in-progress 标签仍然挂着。

需要明确没有要求什么：守卫本身及其测试是正确的，应原样保留——本发现只针对关闭归因。人类评审（评论 5482828147）已确认代码无 Critical，并把本发现的处置留给维护者决定；前几轮的 land-with-residual-risk 建议仍然适用。

建议处理方式：在两个语言部分移除关闭关键字，改为非关闭引用（例如"属于 #10453 调查的一部分"），或取得维护者的明确裁决并在关联 Issue 部分记录非归因。升级上报的第二个崩溃点记录于 #10511。

[Critical] R1-1: [certifies-falsely] [new-surface] Fixes #10453 attributes to this diff an unexplained main-CI failure that this diff demonstrably does not change. Still stands this round, re-verified against the live PR state and the tracked run's own job data at the reviewed commit. Issue #10453 tracked exactly one thing: main-CI run 33228441400, whose only failed job was E2E Test - macOS - shard 2/2 on a GitHub-hosted macos-latest runner, dead before any test result was reported. Replaying that run against the post-change workflow: this diff touches only the startup language-file write; the run's pre-test steps are untouched; the new try/catch fires only on a host whose global config dir is unwritable, and GitHub-hosted macOS runners have writable HOMEs (the same lane's other shard passed) — so every step of the tracked run completes exactly as before. On merge, project history records this PR as the resolution of that undiagnosed failure while the failure family provably continues (successor issue #10473 carries the identical "before any test result was reported" signature). The autofix claim protocol on the issue — "If the attempt fails, this claim will be withdrawn so a human can take over" — was never honored: issue #10453 was closed 2026-08-29T06:43:13Z with no rationale, no withdrawal comment, and the autofix/in-progress label still attached, so no human inherited the unexplained run. The PR's own Risk & Scope ("The exact cause of the original CI run 33228441400 could not be confirmed from this environment ... no change to CI machinery is made") contradicts the Fixes line in the same body.

[Critical] R1-1: [certifies-falsely] [new-surface] Fixes #10453 attributes to this diff an unexplained main-CI failure that this diff demonstrably does not change. Still stands this round — re-verified against the live PR state and the code at the reviewed commit; the Fixes #10453 line is unchanged in both language sections of the PR body at HEAD.

Issue #10453 tracked exactly one thing: main-CI run 33228441400, which failed on main before any test result was reported. Replaying that run against the post-change workflow: the pre-test steps that define its signature are untouched by this diff; on hosts with a writable HOME the new try/catch never fires; and even on the author's unwritable-HOME surrogate the lane still fails at the second crash site (ExtensionStore.prepareDirectories). On merge, project history records this PR as the resolution of run 33228441400 while its cause stays undiagnosed, and the failure family provably continues — successor tracking issues carry the identical "no test results reported" signature. The autofix claim protocol's promised human handover ("If the attempt fails, this claim will be withdrawn so a human can take over") was never honored: the issue was closed manually (yiliang114, 2026-08-29, commit_id: null) with no withdrawal comment, no rationale, and the autofix/in-progress label still attached. The PR's own Risk & Scope concedes the run's cause "could not be confirmed from this environment" and that "no change to CI machinery is made" — contradicting the Fixes line in the same body. The guard and its test are correct and should stay as-is; the defect is the closing attribution.

Witness:

Suggested resolution: remove the closing keyword from both Linked Issues sections and reference the issue non-closing (e.g. "Part of the investigation of #10453"), moving the Risk & Scope concession into Linked Issues so the non-attribution is documented where the link is; alternatively obtain an explicit maintainer ruling and record it, including why the issue was closed without the claim withdrawal the protocol promises. Optionally file a follow-up issue owning the escalated ExtensionStore.prepareDirectories crash site.

The fix must not violate the autofix claim protocol on issue #10453 (claim comment by qwen-code-dev-bot, 2026-08-29T02:36:03Z): "If the attempt fails, this claim will be withdrawn so a human can take over." — any resolution must preserve a documented human handover for the unexplained run; the existing close carries no recorded rationale and the autofix/in-progress label is still attached.

Issue #10453 tracks exactly one thing: "A main-branch CI run failed on main before any test result was reported, so this issue is tracked per commit" (run 33228441400). This diff touches only the startup language-file write; the run's pre-test steps (docker lane, npm, build, bundle) are untouched, and on hosts with a writable HOME the new try/catch never fires, so the run completes exactly as before. The PR's own E2E report concedes: "neither alone explains run 33228441400's 'no test results reported' signature. The most probable cause of that run remains a pre-test step." On merge, the closing keyword archives the actually-observed red run as "fixed" while its cause remains unknown, and the autofix claim protocol — "If the attempt fails, this claim will be withdrawn so a human can take over" — is bypassed: no human inherits the unexplained run. There is also no follow-up issue owning the escalated extension-store crash site. The guard and its test are correct and should stay as-is; the defect is the closing attribution.

Suggested resolution: remove the closing keyword (reference the issue non-closing, e.g. "Part of the investigation of #10453"), leave #10453 open or obtain an explicit maintainer ruling to close it with the non-attribution documented, and file a follow-up issue for the escalated ExtensionStore.prepareDirectories crash site.

Witness:

gh issue view 10453 (re-checked this round) -> state OPEN, "Main CI failed: E2E Tests on 48ec00834542" gh pr view 10455 --json body -> "## Linked Issues / Fixes #10453" (unchanged) gh search issues "prepareDirectories" --repo QwenLM/qwen-code -> [] (no follow-up issue owns crash site 2) diff = languageUtils.ts + test only; pre-test steps untouched

The fix rests on the autofix claim protocol's own premise (claim comment on issue #10453): "If the attempt fails, this claim will be withdrawn so a human can take over." — the resolution must preserve that human handover, not close the issue out from under it.

中文说明

R1-1：Fixes #10453 会自动关闭一个按提交跟踪"主分支 CI 无法解释的失败"的 issue，而本 diff 已被证明不会改变该失败的任何环节。本轮复查后仍然成立。

issue #10453 跟踪的恰好是一件事："主分支的一次 CI 运行在任何测试结果上报之前失败，因此按提交跟踪此问题"（运行 33228441400）。本 diff 只触及启动期语言文件写入；该运行的测试前步骤（docker 通道、npm、构建、打包）均未改动，且在 HOME 可写的主机上新加的 try/catch 根本不会触发，运行结果与之前完全相同。本 PR 自己的 E2E 报告也承认："两者都无法单独解释运行 33228441400 的'没有任何测试结果上报'特征。该次运行最可能的原因仍是测试前的步骤。"合并后，关闭关键字会把实际观察到的红色运行归档为"已修复"，而其原因仍然未知，autofix 认领协议——"如果尝试失败，该认领将被撤回，以便人类接管"——被绕过：没有人接手这次无法解释的运行。此外也没有任何后续 issue 承接被升级上报的扩展存储崩溃点。守卫本身及其测试是正确的，应原样保留；缺陷在于关闭归因。

建议处理方式：移除关闭关键字（改为非关闭引用，例如"属于 #10453 调查的一部分"），让 #10453 保持打开，或取得维护者的明确裁决并在记录非归因的前提下关闭，同时为升级上报的 ExtensionStore.prepareDirectories 崩溃点建立后续 issue。

见证：

gh issue view 10453（本轮复查）→ 状态 OPEN，"Main CI failed: E2E Tests on 48ec00834542" gh pr view 10455 --json body → "## Linked Issues / Fixes #10453"（未变） gh search issues "prepareDirectories" --repo QwenLM/qwen-code → []（没有后续 issue 承接崩溃点 2） diff = 仅 languageUtils.ts + 测试；测试前步骤未改动

该修复依赖 autofix 认领协议自身的前提（issue #10453 上的认领评论）："如果尝试失败，该认领将被撤回，以便人类接管。"——处理方式必须保留这一人类接管机制，而不是在机制之下把 issue 关掉。

[Critical] R1-1: [certifies-falsely] [new-surface] Fixes #10453 attributes to this diff a main-CI failure that this diff demonstrably does not change. Re-checked this round against the live PR state — the attribution defect still stands.

Issue #10453 tracked exactly one thing: "A main-branch CI run failed on main before any test result was reported, so this issue is tracked per commit" (run 33228441400). This diff touches only the startup language-file write; the run's pre-test steps (docker lane, npm, build, bundle) are untouched, and on hosts with a writable HOME the new try/catch never fires, so the run completes exactly as before. The PR's own Risk & Scope concedes: "The exact cause of the original CI run 33228441400 could not be confirmed from this environment … its 'no test results reported' signature points at a pre-test/environment failure, and no change to CI machinery is made." Even under the PR's own hypothesis the lane still fails after this fix: "on such a host the run still stops at a second, separate unwritable-dir site in the extension store."

One development this round: issue #10453 is already CLOSED — closed by yiliang114 at 2026-08-29T06:43:14Z with no comment, no rationale, and no interaction with this PR. That pre-empts the merge-time auto-close the earlier rounds predicted, but it does not resolve the defect: the body still says Fixes #10453, so on merge the project history records this PR as the resolution of run 33228441400 while the cause remains undiagnosed, the failure family is provably ongoing (successor tracking issues #10473, #10475, #10476, #10478, #10482, #10487 all OPEN after the close), and no issue owns the escalated ExtensionStore.prepareDirectories crash site (gh search issues "prepareDirectories" → []). The autofix claim protocol the fix rests on — "If the attempt fails, this claim will be withdrawn so a human can take over" — still has no documented handover tying that close to this remedy.

Suggested resolution: remove the closing keyword (reference the issue non-closing, e.g. "Part of the investigation of #10453"), or obtain an explicit maintainer ruling and document the non-attribution in the Linked Issues section (the concession already exists in Risk & Scope; it currently contradicts the Fixes line in the same body). File a follow-up issue for the escalated ExtensionStore.prepareDirectories crash site. The guard and its test are correct and should stay as-is.

Witness:

gh pr view 10455 --json body | grep Fixes → 39:Fixes #10453 / 82:Fixes #10453 (unchanged this round) gh issue view 10453 → state CLOSED; timeline {"actor":"yiliang114","created_at":"2026-08-29T06:43:14Z","event":"closed"} with no closer comment Successor main-CI tracking issues #10473 / #10475 / #10476 / #10478 / #10482 / #10487 → all OPEN gh search issues "prepareDirectories" --repo QwenLM/qwen-code → [] (no follow-up issue owns the escalated crash site)

The fix must not violate the autofix claim protocol on issue #10453 (claim comment by qwen-code-dev-bot): "If the attempt fails, this claim will be withdrawn so a human can take over." — the resolution must preserve a documented human handover; the existing human close (yiliang114, 2026-08-29T06:43:14Z) has no recorded rationale.

R1-1：[certifies-falsely] [new-surface] Fixes #10453 把一个本 diff 已被证明无法改变的主分支 CI 失败归因于本 PR。本轮按 PR 实时状态复查——归因缺陷仍然成立。

issue #10453 跟踪的恰好是一件事："主分支的一次 CI 运行在任何测试结果上报之前失败，因此按提交跟踪此问题"（运行 33228441400）。本 diff 只触及启动期语言文件写入；该运行的测试前步骤（docker 通道、npm、构建、打包）均未改动，且在 HOME 可写的主机上新加的 try/catch 根本不会触发，运行结果与之前完全相同。本 PR 自己的 Risk & Scope 也承认："原始 CI 运行 33228441400 的确切原因无法从本环境确认……其'没有任何测试结果上报'的特征指向测试前/环境性失败，本 PR 不对 CI 机制做任何改动。"即便按本 PR 自己的假设，修复后该通道仍会失败："在这类主机上运行仍会停在扩展存储中另一个独立的不可写目录崩溃点。"

本轮的一项进展：issue #10453 已被关闭——由 yiliang114 于 2026-08-29T06:43:14Z 关闭，没有任何评论、理由，也没有与本 PR 的任何互动。这抢先于早前几轮预测的合并时自动关闭，但并未解决缺陷本身：PR 描述仍写着 Fixes #10453，合并后项目历史会把本 PR 记录为运行 33228441400 的解决方式，而原因仍未诊断、失败家族被证明仍在持续（关闭之后，后续跟踪 issue #10473、#10475、#10476、#10478、#10482、#10487 全部 OPEN）、也没有任何 issue 承接升级上报的 ExtensionStore.prepareDirectories 崩溃点（gh search issues "prepareDirectories" → []）。该修复所依赖的 autofix 认领协议——"如果尝试失败，该认领将被撤回，以便人类接管"——仍然没有任何书面交接把这次关闭与本修复关联起来。

建议处理方式：移除关闭关键字（改为非关闭引用，例如"属于 #10453 调查的一部分"），或取得维护者的明确裁决并在 Linked Issues 部分记录非归因（该让步已存在于 Risk & Scope，目前与同一描述中的 Fixes 行自相矛盾）。为升级上报的 ExtensionStore.prepareDirectories 崩溃点建立后续 issue。守卫本身及其测试是正确的，应原样保留。

修复不得违反 issue #10453 上的 autofix 认领协议（qwen-code-dev-bot 的认领评论）："如果尝试失败，该认领将被撤回，以便人类接管。"——处理方式必须保留书面的人类交接；现有的人工关闭（yiliang114，2026-08-29T06:43:14Z）没有任何已记录的理由。

[Critical] R1-1: [certifies-falsely] [new-surface] Fixes #10453 attributes to this diff a main-CI failure that this diff demonstrably does not change. Still stands this round, re-verified against the live PR state and newly retrieved job logs.

Issue #10453 tracked exactly one thing: main-CI run 33228441400, which failed on main at commit 48ec00834542. This round the job logs were retrievable, and they show the failing job was E2E Test - macOS - shard 2/2, step Run E2E tests, with a reported vitest failure: cli/qwen-serve-routes.test.ts > advertises all baseline capabilities, assertion diff - "native_directory_picker" — a capability gated by toggles.nativeDirectoryPickerAvailable. Nothing in this diff touches the daemon, that toggle, or that test. Replaying the tracked run against the post-change code: on hosts with a writable HOME the new try/catch never fires and every step completes exactly as before; on unwritable-HOME hosts the run still dies at the second, separate ExtensionStore.prepareDirectories site that this PR's own Risk & Scope concedes. No line of this diff can change the tracked run's outcome under any hypothesis.

On merge, project history records this PR as the resolution of run 33228441400 while the failure family provably continues (successor tracking issue #10473 is OPEN with the identical signature). The autofix claim protocol on issue #10453 — "If the attempt fails, this claim will be withdrawn so a human can take over" — was never honored: the issue was closed manually (yiliang114, 2026-08-29T06:43:14Z) with no withdrawal comment, no rationale, and the autofix/in-progress label still attached. The guard and its test are correct and should stay as-is; the defect is the closing attribution.

Suggested resolution: remove the closing keyword and reference the issue non-closing (e.g. "Part of the investigation of #10453"), moving the non-attribution concession already present in Risk & Scope into the Linked Issues section so the body no longer contradicts itself; or obtain an explicit maintainer ruling and document the non-attribution there. Optionally promote the escalated ExtensionStore.prepareDirectories crash site into its own follow-up issue.

The resolution must not violate the autofix claim protocol on issue #10453 (claim comment by qwen-code-dev-bot, 2026-08-29T02:36:03Z): "If the attempt fails, this claim will be withdrawn so a human can take over." — it must preserve a documented human handover for the unexplained run; the existing manual close carries no recorded rationale.

[Critical] R1-1: [certifies-falsely] [new-surface] Fixes #10453 attributes to this diff a main-CI failure that this diff demonstrably did not cause and does not change. Still stands this round — and the tracked run's own job log, retrievable now for the first time across these rounds, names a different failure that a different commit had already fixed.

Issue #10453 tracked exactly one thing: main-CI run 33228441400, which failed on main before any test result was reported. That run's only failing job is E2E Test - macOS - shard 2/2 on a GitHub-hosted macos-latest runner, failing at step 8 Run E2E tests with steps 1-7 all green, on cli/qwen-serve-routes.test.ts > advertises all baseline capabilities: the expected capability list included native_directory_picker, which isNativeDirectoryPickerAvailable() cannot report on that runner. It was fixed on main by 03a9fb72e2 fix(test): probe the native directory picker once at daemon spawn time (#10456), authored 2026-08-29 06:42:55Z and already an ancestor of this PR's head; #10453 was closed 19 seconds later at 06:43:14Z. Meanwhile cli/qwen-config-dir.test.ts — the very test this PR names as its reproduction — was GREEN in that job, 7 tests passed. No line of this diff touches CI machinery, the capability gate, or that test.

The attribution also fails against the PR's own narrated incident. Driving the shipped build on a host whose $HOME is unwritable (chmod 555), the CLI still exits 1 at startup after this change; the crash site merely moves from writeOutputLanguageFile to ExtensionStore.prepareDirectories, reached through the unguarded extensionManager.refreshCache() inside Config.initialize. So integration-tests/cli/qwen-config-dir.test.ts > 1d stays red on exactly the host class the description names — which the author's own E2E report concedes ("before the fix — 1 file failed (crash site 1); after the fix — same single file fails at crash site 2"), and which contradicts the Fixes line in the same body whose Risk & Scope says "The exact cause of the original CI run 33228441400 could not be confirmed from this environment ... no change to CI machinery is made". The autofix claim protocol's promised human handover never happened either: #10453 holds exactly one comment (the bot claim), no withdrawal, and autofix/in-progress was labelled at 02:35:59Z and never removed before the close. The failure family continues — 13 Main CI failed issues are open, 9 of them E2E with the byte-identical "before any test result was reported" body (for example #10804, run 33609632018, created 2026-09-02) — and the escalated second crash site sits in open issue #10511, which states it "needs its own follow-up issue, which this flow cannot file on GitHub".

On merge, the closing keyword archives an observed red run as resolved by a diff that the run's own log proves is unrelated, so the recorded cause stays wrong in project history and the commit that actually fixed it goes uncredited.

To be explicit about what is not being asked: the guard and its test are correct and should stay exactly as they are. The pre-diff arm below crashes inside initializeLlmOutputLanguage; the post-diff arm does not. This finding is about the closing attribution only.

Suggested resolution: drop the closing keyword and reference the issue non-closing in both language sections of the PR body — for example "Part of the investigation of #10453: the startup crash was reproduced while surfacing it, but the tracked run 33228441400 failed on a qwen serve capability assertion fixed by #10456, not on this path" — drop (#10453) from the title, and record in Linked Issues that the unwritable-global-dir startup failure is only partly addressed on affected hosts, with the second crash site tracked in #10511 and needing a maintainer decision.

Witness:

The fix must not violate the autofix claim protocol on issue #10453 (claim comment by qwen-code-dev-bot, 2026-08-29T02:36:03Z): "If the attempt fails, this claim will be withdrawn so a human can take over." — any resolution must preserve a documented human handover for the unexplained run, and the existing close carries no withdrawal and no rationale with autofix/in-progress still attached.

中文说明

R1-1：[certifies-falsely] [new-surface] Fixes #10453 把一个本 diff 已被证明既未造成、也无法改变的主分支 CI 失败归因于本 PR。本轮复查——仍然成立；而且这一次首次取到了被跟踪运行自身的任务日志，它指向的是另一个失败，且该失败早已被另一个提交修复。

issue #10453 跟踪的恰好是一件事：主分支 CI 运行 33228441400，在任何测试结果上报之前失败。该次运行唯一失败的任务是 E2E Test - macOS - shard 2/2，跑在 GitHub 托管的 macos-latest 上，第 1-7 步全部成功，失败发生在第 8 步 Run E2E tests，具体是 cli/qwen-serve-routes.test.ts > advertises all baseline capabilities：期望的能力列表包含 native_directory_picker，而 isNativeDirectoryPickerAvailable() 在该 runner 上不可能返回它。该问题已由 03a9fb72e2 fix(test): probe the native directory picker once at daemon spawn time (#10456) 在 main 上修复，作者时间 2026-08-29 06:42:55Z，且已是本 PR head 的祖先提交；#10453 在 19 秒后（06:43:14Z）被关闭。与此同时，本 PR 自述为复现用例的 cli/qwen-config-dir.test.ts 在该任务中是绿色的（7 个测试全部通过）。本 diff 没有任何一行触及 CI 机制、能力门控或那个测试。

该归因在 PR 自述的事件上同样不成立。在 $HOME 不可写（chmod 555）的主机上驱动已构建产物：本变更之后 CLI 启动仍然以退出码 1 终止，崩溃点只是从 writeOutputLanguageFile 移到了 ExtensionStore.prepareDirectories——后者经由 Config.initialize 中未加保护的 extensionManager.refreshCache() 到达。因此在描述所指的那一类主机上，integration-tests/cli/qwen-config-dir.test.ts > 1d 依旧是红的；作者自己的 E2E 报告也承认这一点（"修复前 — 1 个文件失败（崩溃点 1）；修复后 — 同一文件在崩溃点 2 失败"），而这与同一描述中的 Fixes 行自相矛盾——其 Risk & Scope 写着"原始 CI 运行 33228441400 的确切原因无法从本环境确认……本 PR 不对 CI 机制做任何改动"。autofix 认领协议承诺的人类交接也从未兑现：#10453 只有一条评论（机器人认领），没有撤回，autofix/in-progress 于 02:35:59Z 打上、在关闭前从未移除。失败家族仍在持续——当前有 13 个 Main CI failed issue 处于打开状态，其中 9 个是 E2E、正文逐字节相同（例如 #10804，运行 33609632018，创建于 2026-09-02）；被升级上报的第二个崩溃点记录在打开的 issue #10511 中，而该 issue 自述"需要自己的后续 issue，而本流程无法在 GitHub 上创建"。

合并后，关闭关键字会把一次实际观察到的红色运行归档为"由本 diff 解决"，而该运行自身的日志证明两者无关——项目历史中的原因记录因此是错的，真正修复它的提交也得不到归属。

需要明确没有要求什么：守卫本身及其测试是正确的，应原样保留。下方的修改前分支在 initializeLlmOutputLanguage 内崩溃，修改后不再崩溃。本发现只针对关闭归因。

建议处理方式：移除关闭关键字，在 PR 描述的两个语言部分改为非关闭引用——例如"属于 #10453 调查的一部分：启动崩溃是在追查该问题时复现的，但被跟踪的运行 33228441400 失败于一个由 #10456 修复的 qwen serve 能力断言，而非本路径"——并从标题中去掉 (#10453)；同时在 Linked Issues 中记录：不可写全局目录导致的启动失败在受影响主机上只被部分解决，第二个崩溃点记录于 #10511，需要维护者决策。

（见证见上方英文部分 Witness 代码块。）

修复不得违反 issue #10453 上的 autofix 认领协议（qwen-code-dev-bot 于 2026-08-29T02:36:03Z 的认领评论）："如果尝试失败，该认领将被撤回，以便人类接管。"——任何处理方式都必须为这次无法解释的运行保留书面的人类交接；现有关闭既无撤回也无理由，且 autofix/in-progress 标签仍然挂着。

This diff touches only the startup language-file write and its test; the tracked run's only failing job (E2E Test - macOS - shard 2/2; all six Linux lanes succeeded) is on a path nothing in this diff reaches, and on hosts with a writable HOME the new try/catch never fires. On merge, project history records this PR as the resolution of run 33228441400 while its cause stays undiagnosed and the commit that actually touched the failure goes uncredited. The autofix claim protocol's promised human handover — "If the attempt fails, this claim will be withdrawn so a human can take over" — was never honored: issue #10453 was closed manually (2026-08-29T06:43:13Z, commit_id null) with no withdrawal comment, no rationale, and the autofix/in-progress label still attached, and the six successor tracking issues (10473/10475/10476/10478/10482/10487) were closed the same way on 2026-08-31, likewise with no fix attributed. The PR body contradicts itself: Risk & Scope concedes "The exact cause of the original CI run 33228441400 could not be confirmed from this environment ... no change to CI machinery is made" while both language sections still say Fixes #10453. The guard and its test are correct and should stay as-is; the defect is the closing attribution.

Witness:

gh pr view 10455 body -> "## Linked Issues / Fixes #10453" and "## 关联 Issue / Fixes #10453" same body: "The exact cause of the original CI run 33228441400 could not be confirmed ... no change to CI machinery is made" gh api issues/10453 -> state CLOSED 2026-08-29T06:43:13Z, label autofix/in-progress attached, sole comment = bot claim, no withdrawal timeline close -> {actor: yiliang114, commit_id: null} gh run view 33228441400 -> only failure: E2E Test - macOS - shard 2/2 git merge-base --is-ancestor 03a9fb72e2 HEAD -> exit 0

Suggested resolution: drop the closing keyword in both language sections and reference the issue non-closing (e.g. "Part of the investigation of #10453"), or obtain an explicit maintainer ruling and document the non-attribution in the Linked Issues section; reopen #10453 or document why it was closed without the promised withdrawal.

The fix must not violate the autofix claim comment on issue #10453 (qwen-code-dev-bot, 2026-08-29T02:36:03Z): "If the attempt fails, this claim will be withdrawn so a human can take over." — the resolution must preserve a documented human handover for the unexplained run; the existing close carries no recorded rationale.

中文说明

R1-1：[certifies-falsely] [new-surface] Fixes #10453 把一个本 diff 已被证明既非其原因、也无法改变的主分支 CI 失败归因于本 PR。本轮按 PR 实时状态与被跟踪运行自身的数据复查——仍然成立。issue #10453 跟踪的恰好是一件事：主分支的一次 CI 运行（运行 33228441400）在任何测试结果上报之前失败。本 diff 只触及启动期语言文件写入及其测试；被跟踪运行中唯一失败的任务（E2E Test - macOS - shard 2/2；六条 Linux 通道全部成功）所处的环节是本 diff 没有任何一行能触及的，且在 HOME 可写的主机上新加的 try/catch 根本不会触发。合并后，项目历史会把本 PR 记录为运行 33228441400 的解决方式，而其原因仍未诊断、真正触及该失败的提交也得不到任何署名。autofix 认领协议承诺的人类交接——"如果尝试失败，该认领将被撤回，以便人类接管"——始终没有兑现：issue #10453 被人工关闭（2026-08-29T06:43:13Z，commit_id 为 null），没有任何撤回评论、没有理由，autofix/in-progress 标签仍然挂着；六个后续跟踪 issue（10473/10475/10476/10478/10482/10487）也在 2026-08-31 以同样方式关闭，同样没有把修复归因到任何 PR。本 PR 描述自相矛盾：Risk & Scope 承认"原始 CI 运行 33228441400 的确切原因无法从本环境确认……本 PR 不对 CI 机制做任何改动"，而两个语言版本的关联 Issue 部分却都写着 Fixes #10453。守卫本身及其测试是正确的，应原样保留；缺陷在于关闭归因。

建议处理方式：在两个语言版本中移除关闭关键字（改为非关闭引用，例如"属于 #10453 调查的一部分"），或取得维护者的明确裁决并在 Linked Issues 部分记录非归因；重新打开 #10453，或记录其在没有承诺的撤回的情况下被关闭的原因。

修复不得违反 issue #10453 上的 autofix 认领评论（qwen-code-dev-bot，2026-08-29T02:36:03Z）："如果尝试失败，该认领将被撤回，以便人类接管。"——处理方式必须为这次无法解释的运行保留书面的人类交接；现有关闭没有任何已记录的理由。

[Suggestion] R1-3: The swallowed creation failure leaves no diagnostic trace — when the global dir is unwritable, the user's configured output language silently never takes effect. Still stands this round — the catch is still empty, and three independent audit agents re-derived the same defect independently this round.

A user with general.outputLanguage set (e.g. "Chinese") on an unwritable ~/.qwen (root-owned leftovers, read-only container, ENOSPC) now hits this catch on every startup; because loadCliConfig (config.ts:1394-1401) only registers the rule file when it exists, the language instruction never reaches any session context and responses ignore the configured language indefinitely. Before this diff the startup crash itself signalled the problem; now there is zero log output — an oncall page for "my language setting doesn't work" has no thread to pull. The codebase already logs this exact failure class elsewhere: debugLogger.warn('Failed to write output-language.md:', err) on the ACP /language path (acpAgent.ts:10432 at the reviewed commit). Bind the error and log through the house debug channel (const debugLogger = createDebugLogger('I18N'), same pattern as languageCommand.ts):

} catch (err) { debugLogger.warn('Failed to create output-language rule file:', err); }

Keep it debug-only, since writing to stderr at startup would risk corrupting TUI/ACP output.

Witness:

witness: not run — probe; the defect is the absence of any statement in a catch block quoted in full from the diff (and no logger import in the file), so no run can observe the absence more directly than the code text; the acpAgent.ts precedent and the non-throwing-log claim were verified by reading the cited lines.

The fix must not violate an existing fact: writeLog in packages/core/src/utils/debugLogger.ts:143-147 ends with .catch(() => { hasWriteFailure = true; }), so debugLogger.warn is non-throwing on an unwritable home and cannot re-introduce the startup crash. Extend the new test to also assert the debug logger was called with the path and error (mocking createDebugLogger); removing the log call must make that assertion fail — please confirm by the removal-and-rerun mutation.

R1-3：被吞掉的创建失败没有留下任何诊断痕迹——当全局目录不可写时，用户配置的输出语言会悄无声息地永远不生效。本轮仍然成立——catch 依然是空的，且本轮三个独立的审计视角各自重新得出了同一缺陷。

一个设置了 general.outputLanguage（例如 "Chinese"）的用户，在 ~/.qwen 不可写（root 所有的遗留文件、只读容器、ENOSPC）时，现在每次启动都会落进这个 catch；由于 loadCliConfig（config.ts:1394-1401）只在规则文件存在时才注册它，语言指令永远不会进入任何会话上下文，回复将无限期地无视已配置的语言。在本 diff 之前，启动崩溃本身就是问题的信号；现在日志输出为零——"我的语言设置不起作用"的 oncall 工单没有任何线索可查。代码库在其他地方已经为这一完全相同的失败类别打过日志：ACP /language 路径上的 debugLogger.warn('Failed to write output-language.md:', err)（审查提交上为 acpAgent.ts:10432）。建议绑定错误并通过项目内的调试通道打日志（const debugLogger = createDebugLogger('I18N')，与 languageCommand.ts 相同的模式，见上方代码块）——保持仅调试输出，因为在启动时写 stderr 有破坏 TUI/ACP 输出的风险。

见证：

witness: not run — probe；缺陷是 diff 中完整引用的 catch 块里没有任何语句（且该文件没有 logger 导入），因此任何运行都无法比代码文本本身更直接地观测这种"缺失"；acpAgent.ts 的先例与"日志不会抛异常"的论断均通过阅读所引用的代码行核实。

修复不得违反一个既有事实：packages/core/src/utils/debugLogger.ts:143-147 中的 writeLog 以 .catch(() => { hasWriteFailure = true; }) 结尾，因此 debugLogger.warn 在不可写的 HOME 上不会抛异常，不会重新引入启动崩溃。请扩展新测试，同时断言调试日志以路径和错误为参被调用（mock createDebugLogger）；移除该日志调用必须使该断言失败——请通过"移除后重跑"的变异来确认。

[Suggestion] R1-5: By letting unwritable-~/.qwen hosts boot, this diff newly exposes the ACP route qwen/settings/setCoreValue, whose updateOutputLanguageFile(normalizedValue) call is unguarded and runs after the setting was already persisted. Still stands this round — mechanism re-verified at the reviewed commit (line numbers shifted by the main merge since round 1: route now at acpAgent.ts:11737, unguarded call at acpAgent.ts:11773).

On a host where ~/.qwen exists but is unwritable while a user-owned writable settings.json already exists and no output-language.md exists, the ACP agent previously crashed at startup and the route was unreachable; now it boots. When the IDE sends qwen/settings/setCoreValue for general.outputLanguage, settings.setValue persists to the existing settings.json, then writeFileSync fails with EACCES; extMethod's error mapping only covers session-writer errors and rethrows the rest, so the request fails with an opaque internal error while the setting is already on disk — the IDE reports the change as failed though it persisted, every subsequent startup's creation retry is silently swallowed by this diff's catch, the configured language never takes effect, and there is no log anywhere. The sibling /language path guards the identical write with fileWriteOk + debugLogger.warn (acpAgent.ts:10421-10433). Guard at the route call site, mirroring that path:

try { updateOutputLanguageFile(normalizedValue); } catch (err) { debugLogger.warn('Failed to write output-language.md:', err); }

— or gate settings.setValue on write success like fileWriteOk does.

Witness:

Probe in scratch tree, updateOutputLanguageFile mocked to throw EACCES: intact PR -> PROBE-OUTCOME: REJECTED: EACCES: permission denied, open '/root/.qwen/output-language.md' PROBE-SETVALUE-CALLS: [["User","general.outputLanguage","Japanese"]] PROBE-USER-SETTINGS-AFTER: {"general":{"outputLanguage":"Japanese"}} (failed response, persisted setting) with fix -> PROBE-OUTCOME: RESOLVED with the same setValue calls (probe flips); pre-existing happy-path test still passes

The fix must not violate an existing fact: the /language sync path gates its persistence of general.outputLanguage on the write succeeding via fileWriteOk (acpAgent.ts:10421-10433), so updateOutputLanguageFile/writeOutputLanguageAndRegisterPath must keep throwing and the catch belongs at the route call site, not inside languageUtils.ts. The acceptance criterion is a failure-path sibling of the existing 'qwen/settings setCoreValue syncs output language rule file' test in packages/cli/src/acp-integration/acpAgent.test.ts: mock updateOutputLanguageFile to throw EACCES, call agent.extMethod('qwen/settings/setCoreValue', {scope: 'user', key: 'general.outputLanguage', value: 'Japanese'}), assert it resolves and settings.setValue was still called — removing the catch must make it go red.

中文说明

R1-5：通过让 ~/.qwen 不可写的主机也能启动，本 diff 新暴露了 ACP 路由 qwen/settings/setCoreValue——其中的 updateOutputLanguageFile(normalizedValue) 调用没有任何保护，且运行在设置已经持久化之后。本轮仍然成立——机制已在审查提交上重新核实（自上一轮以来行号因 main 合入而移动：路由现位于 acpAgent.ts:11737，未加保护的调用位于 acpAgent.ts:11773）。

在一台 ~/.qwen 存在但不可写、其中已有用户可写的 settings.json、且尚无 output-language.md 的主机上，ACP agent 之前会在启动时崩溃、该路由不可达；现在它能启动了。当 IDE 为 general.outputLanguage 发送 qwen/settings/setCoreValue 时，settings.setValue 会先持久化到已有的 settings.json，随后 writeFileSync 以 EACCES 失败；extMethod 的错误映射只覆盖 session-writer 错误、其余原样重抛，于是请求以一个不透明的内部错误失败，而设置其实已经落盘——IDE 报告修改失败，实际已经持久化；此后每次启动的创建重试都被本 diff 的 catch 静默吞掉，配置的语言永远不生效，且任何地方都没有日志。同文件的 /language 路径用 fileWriteOk + debugLogger.warn（acpAgent.ts:10421-10433）保护了同一写入。建议在路由调用点加保护，与该路径对齐（见上方代码块）——或者像 fileWriteOk 那样把 settings.setValue 置于写入成功之后。

见证：

scratch tree 中的探针，updateOutputLanguageFile 被 mock 为抛 EACCES：完整 PR → PROBE-OUTCOME: REJECTED: EACCES: permission denied, open '/root/.qwen/output-language.md' PROBE-SETVALUE-CALLS: [["User","general.outputLanguage","Japanese"]] PROBE-USER-SETTINGS-AFTER: {"general":{"outputLanguage":"Japanese"}} （响应失败，但设置已持久化）含修复 → PROBE-OUTCOME: RESOLVED，setValue 调用相同（探针翻转）；既有 happy-path 测试仍然通过

修复不得违反一个既有事实：/language 同步路径通过 fileWriteOk（acpAgent.ts:10421-10433）把 general.outputLanguage 的持久化置于写入成功之后，因此 updateOutputLanguageFile/writeOutputLanguageAndRegisterPath 必须继续抛异常，catch 应放在路由调用点，而不是 languageUtils.ts 内部。验收标准是 packages/cli/src/acp-integration/acpAgent.test.ts 中既有 'qwen/settings setCoreValue syncs output language rule file' 测试的失败路径对称用例：把 updateOutputLanguageFile mock 为抛 EACCES，调用 agent.extMethod('qwen/settings/setCoreValue', {scope: 'user', key: 'general.outputLanguage', value: 'Japanese'})，断言其 resolve 且 settings.setValue 仍被调用——移除该 catch 必须使它变红。
