Re-run at maintainer request — the branch moved since the last triage (the fix approach changed; see below), so this pass re-checks everything against the current head. Template: complete ✓ — all required sections present, bilingual. Problem: the flake itself is real and was reproduced: the lane repro on unmodified Direction: aligned — a test-only CI-reliability fix for the shared runner pool is squarely in scope. Size: no core paths touched; 0 production logic lines (one test file, +10/−3, all test code). Stage 0 not applicable. Approach: the diff is no longer what the body describes. The original timeout-bump commits were replaced during the review loop by a root-cause restructure: the exhaustive sweep now collects mismatches and asserts once per run instead of asserting 65,536 times, which removes the per-assertion overhead that made the test's wall time load-dependent. Two hygiene problems, non-blocking but real: (1) the PR body is stale — it still describes the abandoned timeout approach ("no assertion is removed, weakened, or retried — only the timeout ceiling changes"), which is now false of the diff; (2) the body still says Risk: no elevated risk signals — test-only file, nothing matches the high-risk path screen. Moving on to code review. 🔍 中文说明应维护者要求重跑——自上次 triage 以来分支已移动（修复方案有变，见下文），因此本轮针对当前 head 重新检查所有内容。 模板：完整 ✓ —— 所有必需小节齐全，中英双语。 问题：抖动本身真实存在且已复现：在未改动的 方向：对齐——针对共享运行器池的纯测试 CI 可靠性修复，完全在项目范围内。 规模：未触及核心路径；0 行生产逻辑（单个测试文件，+10/−3，全部为测试代码）。Stage 0 不适用。 方案：diff 已不再是 PR 正文所描述的内容。最初的"提高超时"提交在评审循环中被根因重构取代：穷举扫描改为收集不匹配项并在每轮只断言一次，而不是断言 65,536 次——这消除了使该测试墙上时间随负载变化的逐项断言开销。两个卫生问题，不阻塞但确实存在：(1) PR 正文已过期——仍在描述被放弃的超时方案（"没有删除、放宽或重试任何断言——只改变超时上限"），这对当前 diff 已不成立；(2) 正文仍写着 风险：无升级风险信号——纯测试文件，未命中任何高风险路径筛查。 进入代码审查。🔍 — Qwen Code · qwen3.8-max Reviewed at |

Confidence: 4/5 — a clean, root-cause deflake with CI evidence for the changed test; the only reservations are metadata (a stale body and a disproven Stepping back: the approach this PR finally carries is the one I'd have proposed — the flake lived in 65,536 per-iteration assertions, so the fix collects mismatches and asserts once, and the wall time collapses from ~4–6.5s to 324ms as measured in this commit's own CI log, on a runner visibly under contention. Pass/fail semantics are preserved and the failure diagnostics survive in bounded form; the code is ten lines in one test file and nothing else. The workflow around the PR is messier than the code: the body still describes the abandoned timeout approach and still says Approving with CI complete-but-not-green on this commit: the decisive evidence for the change itself exists in the partial run, and every red/cancelled check is evidenced as infra, consequential, or unrelated.

[Critical] R1-1: [certifies-falsely] [new-surface] This PR claims to fix issue #10529 (Fixes #10529, branch autofix/issue-10529, commit title (#10529)), but the failure recorded in that issue happened in a different test that this PR never touches — and the acp-bridge vitest suite never even ran in the referenced CI run. Issue #10529 tracks CI run 33274358974 (job 99165081177), which failed in the Run .github/scripts helper tests step with not ok 17 - autofix-status-heartbeat loop (failing subtest stamps each tick in flight around the gh call and clears it after, error expected at least two PATCH calls with stamp observations), TAP summary # tests 489 / # pass 488 / # fail 1. The job ended at that step, so the Run tests and generate reports step that would have executed packages/acp-bridge's vitest suite was skipped entirely. The timeout raise here may be a legitimate deflake for a flake observed elsewhere, but as shipped, merging auto-closes #10529 while the failure it records remains unaddressed. Retarget the autofix at the test that actually failed — the autofix-status-heartbeat loop suite in .github/scripts/autofix-status-heartbeat.test.mjs (failing subtest at line 215) — or drop the Fixes #10529 linkage (and the (#10529) reference) and name the separate evidence for the flake this fixes, since issue #10529 provides none.

中文说明
本 PR 声称修复 issue #10529（Fixes #10529、分支 autofix/issue-10529、提交标题 (#10529)），但该 issue 记录的失败发生在本 PR 从未触碰的另一个测试中——而且在被引用的 CI 运行中，acp-bridge 的 vitest 套件根本没有执行。Issue #10529 追踪的是 CI 运行 33274358974（job 99165081177），该运行在 Run .github/scripts helper tests 步骤失败于 not ok 17 - autofix-status-heartbeat loop（失败子测试 stamps each tick in flight around the gh call and clears it after，错误 expected at least two PATCH calls with stamp observations），TAP 汇总为 # tests 489 / # pass 488 / # fail 1。任务在该步骤终止，因此本应执行 packages/acp-bridge vitest 套件的 Run tests and generate reports 步骤被完全跳过。这里的超时上调本身可能确实是针对别处观测到的抖动的合理消抖，但按当前提交合并会自动关闭 #10529，而该 issue 记录的失败仍然无人处理。请将 autofix 重新对准实际失败的测试——.github/scripts/autofix-status-heartbeat.test.mjs 中的 autofix-status-heartbeat loop 套件（失败子测试位于第 215 行）——或者移除 Fixes #10529 关联（以及 (#10529) 引用），并在 PR 描述中给出本次修复所针对抖动的独立证据，因为 issue #10529 并不提供该证据。

Disposition: escalated to a maintainer — the finding is verified, but neither offered remediation is implementable by this bot, so this thread stays open.
The finding was re-verified against the code at HEAD this round: this PR's diff touches only packages/acp-bridge/src/json-string-bytes.test.ts; git diff 02f2101f43..HEAD -- .github/scripts/ is empty; the failing subtest stamps each tick in flight around the gh call and clears it after exists at .github/scripts/autofix-status-heartbeat.test.mjs:866. The Fixes #10529 certification is indeed wrong.
Why this round implements neither offered remediation:
- Retarget (deflake the heartbeat suite) — the fix lives in
.github/scripts/, a protected area for this bot: the standing address-review boundary forbids modifying CI or verification machinery the PR was not already about (.github/in general, and the autofix loop's own machinery in particular —autofix-status-heartbeat.shis the autofix round status-comment heartbeat, launched and killed byqwen-autofix.ymlitself), and the deterministic footprint gate rejects rounds expanding outside this PR'spackages/acp-bridgefootprint. Feedback requesting such a change is escalated to a maintainer, not implemented. - Unlink (drop
Fixes #10529) — the closing keyword sits in the PR body, which is set only at PR creation (the address-review path has no PR-body/title edit mechanism), and the(#10529)title reference sits in already-pushed commita623924a80, which cannot be amended (additive commits only).
Question for the maintainer: how should the false linkage be repaired — (a, recommended) edit the PR body to drop Fixes #10529 and merge this as a standalone deflake whose evidence is the local reproduction in the E2E report, leaving #10529 open to track the heartbeat failure; or (b) close this PR and deflake the heartbeat suite under #10529 as maintainer-owned work? The heartbeat deflake itself is recorded in deferred-findings.json so it survives this PR's merge either way.

处置：已升级给维护者——该发现经核实成立，但两种补救方式机器人均无法实施，因此本线程保持打开。
本轮已在 HEAD 代码上复核该发现：本 PR 的差异只触碰 packages/acp-bridge/src/json-string-bytes.test.ts；git diff 02f2101f43..HEAD -- .github/scripts/ 为空；失败子测试 stamps each tick in flight around the gh call and clears it after 位于 .github/scripts/autofix-status-heartbeat.test.mjs:866。Fixes #10529 认证确实是错误的。
本轮为何不实施任何一种补救方式：
- 重新对准（为心跳套件消抖）——修复位于
.github/scripts/，对机器人是受保护区域：address-review 的常设边界禁止修改本 PR 原本不涉及的 CI 或验证机制（.github/整体，尤其是 autofix 循环自身的机制——autofix-status-heartbeat.sh就是 autofix 轮次状态评论的心跳，由qwen-autofix.yml亲自启动和终止），且确定性足迹门禁会拒绝扩展到本 PRpackages/acp-bridge足迹之外的轮次。要求此类变更的反馈一律升级给维护者，而不是实施。 - 解除关联（移除
Fixes #10529）——关闭关键字位于 PR 正文，而 PR 正文只在创建 PR 时设置（address-review 路径没有任何修改 PR 正文/标题的机制）；标题中的(#10529)引用位于已推送的提交a623924a80，不允许 amend（只允许追加式提交）。
请维护者决策： 应如何修复错误关联——（a，推荐）编辑 PR 正文移除 Fixes #10529，将本 PR 作为独立消抖合并（其证据为 E2E 报告中的本地复现），让 #10529 保持打开以追踪心跳失败；还是（b）关闭本 PR，在 #10529 下由维护者亲自为心跳套件消抖？心跳消抖本身已记入 deferred-findings.json，无论本 PR 是否合并都不会丢失。

[Critical] R1-1: [certifies-falsely] [new-surface] This PR claims to fix issue #10529 (Fixes #10529, branch autofix/issue-10529, commit title (#10529)), but the failure recorded in that issue happened in a different test that this PR never touches — and the acp-bridge vitest suite never even ran in the referenced CI run. Round 2: still stands — independently re-verified this round against the raw job log of run 33274358974, which is now readable and proves the opposite attribution.
Issue #10529 records CI run 33274358974 (job 99165081177). That job failed at the Run .github/scripts helper tests step: not ok 17 - autofix-status-heartbeat loop, failing subtest stamps each tick in flight around the gh call and clears it after with error expected at least two PATCH calls with stamp observations, TAP summary # tests 489 / # pass 488 / # fail 1, exit code 1. The job ended at that step, so the Run tests and generate reports step — the vitest step that executes this PR's deflaked test — was skipped entirely. Zero commits between the incident commit 02f2101f43 and this PR's HEAD touch the heartbeat test (git diff 02f2101f43..HEAD -- .github/scripts/ is empty), so merging auto-closes #10529 while the failure it records remains live in the tree: the next main push under comparable load fails the same heartbeat subtest at the same step, the vitest step is again never reached, and main CI goes red with its tracking issue already closed.
The timeout raise itself is a legitimate deflake of a real, separately evidenced flake — the local reproduction in the E2E report (Test timed out in 5000ms on unmodified main, mutation probe under load) is undisputed. The defect is exclusively the Fixes #10529 certification.

git diff 02f2101f43..HEAD -- .github/scripts/ -> (empty)
Either retarget the autofix at the test that actually failed — deflake the autofix-status-heartbeat loop suite in .github/scripts/autofix-status-heartbeat.test.mjs (failing subtest stamps each tick in flight around the gh call and clears it after, line 866 at HEAD; the suite's 52.7s duration under load points at the same contention class) — or drop the Fixes #10529 linkage and the (#10529) commit-title reference, and ship this as a standalone deflake whose evidence is the local reproduction already in the E2E report.
Any deflake of the heartbeat test must keep the deflake standard the issue's E2E report quotes — "no assertion removed, weakened, or retried": the fix may only change the timing budget or scheduling tolerance, not what the subtest observes (source: E2E report on issue #10529, "Fix applied" section).
For the retarget option, the acceptance criterion is the autofix-status-heartbeat loop suite — specifically the stamps each tick in flight around the gh call and clears it after subtest — passing in CI; please prove the fix by relaxing the new tolerance again and confirming that subtest goes red.

本 PR 声称修复 issue #10529（Fixes #10529、分支 autofix/issue-10529、提交标题 (#10529)），但该 issue 记录的失败发生在本 PR 从未触碰的另一个测试中——而且在被引用的 CI 运行中，acp-bridge 的 vitest 套件根本没有执行。第 2 轮：仍然成立——本轮已对照 run 33274358974 的原始任务日志独立复核（该日志现已可读），其内容证明的归因与 PR 的归因相反。
Issue #10529 记录的是 CI 运行 33274358974（job 99165081177）。该任务在 Run .github/scripts helper tests 步骤失败：not ok 17 - autofix-status-heartbeat loop，失败子测试 stamps each tick in flight around the gh call and clears it after，错误 expected at least two PATCH calls with stamp observations，TAP 汇总 # tests 489 / # pass 488 / # fail 1，退出码 1。任务在该步骤终止，因此本应执行 vitest（即本 PR 消抖测试所在步骤）的 Run tests and generate reports 被完全跳过。从事故提交 02f2101f43 到本 PR HEAD 之间没有任何提交触碰该心跳测试（git diff 02f2101f43..HEAD -- .github/scripts/ 为空），因此按当前提交合并会自动关闭 #10529，而该 issue 记录的失败仍然留在代码树中：下一次在相近负载下推送 main 会在同一步骤失败于同一个心跳子测试，vitest 步骤再次无法执行，main CI 再次变红而其追踪 issue 已被关闭。
超时上调本身是对一个真实存在、另有独立证据的抖动的合理消抖——E2E 报告中的本地复现（未改动 main 上 Test timed out in 5000ms、负载下的变异探针）没有争议。缺陷仅在于 Fixes #10529 这一认证。
修复方式二选一：将 autofix 重新对准实际失败的测试——对 .github/scripts/autofix-status-heartbeat.test.mjs 中的 autofix-status-heartbeat loop 套件做消抖（失败子测试 stamps each tick in flight around the gh call and clears it after，HEAD 上位于第 866 行；该套件在负载下 52.7 秒的耗时指向同一争用类别）；或者移除 Fixes #10529 关联与 (#10529) 引用，将本改动作为独立消抖提交，其证据即 E2E 报告中已有的本地复现。
对心跳测试的任何消抖都必须保持该 issue E2E 报告引用的消抖标准——"不删除、不放宽、不重试任何断言"：修复只能改变时间预算或调度容忍度，不能改变子测试所观测的内容（来源：issue #10529 的 E2E 报告"应用的修复"一节）。
若选择重新对准，验收标准是 autofix-status-heartbeat loop 套件——特别是 stamps each tick in flight around the gh call and clears it after 子测试——在 CI 中通过；请通过再次放宽新设置的容忍度并确认该子测试变红来证明修复有效。

Disposition: escalated to a maintainer — round-2 re-verification confirmed, but neither offered remediation is implementable by this bot, so this thread stays open.
The round-2 evidence was independently confirmed against the local tree this round: git diff 02f2101f43..HEAD -- .github/scripts/ is empty (the heartbeat suite is untouched since the incident commit), the failing subtest stamps each tick in flight around the gh call and clears it after sits at .github/scripts/autofix-status-heartbeat.test.mjs:866 at HEAD exactly as cited, and this PR's entire diff is the acp-bridge timeout raise. The Fixes #10529 certification remains wrong at HEAD.
Why this round implements neither offered remediation:
- Retarget (deflake the heartbeat suite) — the fix lives in

Feedback requesting such a change is escalated to a maintainer, not implemented. The round-2 acceptance criterion (relax the new tolerance and watch the subtest go red) would additionally require load-controlled reproduction of a timing flake in exactly that protected area. - Unlink (drop
Fixes #10529) — the closing keyword sits in the PR body, which is set only at PR creation (the address-review path has no PR-body/title edit mechanism), and the(#10529)title reference sits in already-pushed commita623924a80, which cannot be amended (additive commits only).
Question for the maintainer: how should the false linkage be repaired — (a, recommended) edit the PR body to drop Fixes #10529 and merge this as a standalone deflake whose evidence is the local reproduction in the E2E report (re-verified green at HEAD this round: 5/5 tests, exhaustive sweep ~2.6s), leaving #10529 open to track the heartbeat failure; or (b) close this PR and deflake the heartbeat suite under #10529 as maintainer-owned work (keeping the issue's standard: no assertion removed, weakened, or retried)? The heartbeat deflake itself is recorded in deferred-findings.json so it survives this PR's merge either way.

That job failed at the Run .github/scripts helper tests step — subtest stamps each tick in flight around the gh call and clears it after in .github/scripts/autofix-status-heartbeat.test.mjs:866, error expected at least two PATCH calls with stamp observations — while the vitest step Run tests and generate reports, where this PR's deflaked test lives, was skipped. .github/scripts/ is byte-identical to the incident commit (git diff 02f2101f43..HEAD -- .github/scripts/ is empty), and the PR body still carries Fixes #10529: merging auto-closes #10529 while the failure it records remains live in the tree — the next main push under comparable load fails the same heartbeat subtest at the same step, the vitest step is again skipped before the new 60_000 ceiling ever executes, and main CI goes red with its tracking issue already closed.
Either (a) retarget the autofix at the test that actually failed — deflake the autofix-status-heartbeat loop suite in .github/scripts/autofix-status-heartbeat.test.mjs (failing subtest stamps each tick in flight around the gh call and clears it after, line 866) — or (b) drop the Fixes #10529 linkage (and the (#10529) commit-title reference) and ship this as a standalone deflake whose evidence is the local reproduction already in the E2E report.

Any heartbeat deflake must keep the deflake standard the E2E report on issue #10529 states — "no assertion removed, weakened, or retried": only the timing budget may change, not what the subtest observes (source: E2E report comment 5465732753 on issue #10529, "Fix applied" section; mirrored in the PR body). For the retarget option, the acceptance criterion is the stamps each tick in flight around the gh call and clears it after subtest passing in CI — please prove the fix by relaxing the new tolerance again and confirming that subtest goes red.
中文说明
本 PR 声称修复 issue #10529（Fixes #10529、分支 autofix/issue-10529、提交标题 (#10529)），但该 issue 记录的失败发生在本 PR 从未触碰的另一个测试中——而且在被引用的 CI 运行中，acp-bridge 的 vitest 套件根本没有执行。第 3 轮：仍然成立——本轮已对照该次运行的实时状态、原始任务日志与 HEAD 代码独立复核。
Issue #10529 记录的是提交 02f2101f4305 上的 CI 运行 33274358974。该任务在 Run .github/scripts helper tests 步骤失败——.github/scripts/autofix-status-heartbeat.test.mjs:866 的子测试 stamps each tick in flight around the gh call and clears it after，错误 expected at least two PATCH calls with stamp observations——而本 PR 消抖测试所在的 vitest 步骤 Run tests and generate reports 被跳过。.github/scripts/ 与事故提交逐字节相同（git diff 02f2101f43..HEAD -- .github/scripts/ 为空），且 PR 正文仍含 Fixes #10529：按当前状态合并会自动关闭 #10529，而该 issue 记录的失败仍留在代码树中——下一次在相近负载下推送 main 会在同一步骤失败于同一个心跳子测试，vitest 步骤再次在新的 60_000 上限执行之前被跳过，main CI 再次变红而其追踪 issue 已被关闭。
修复方式二选一：(a) 将 autofix 重新对准实际失败的测试——对 .github/scripts/autofix-status-heartbeat.test.mjs 中的 autofix-status-heartbeat loop 套件做消抖（失败子测试 stamps each tick in flight around the gh call and clears it after，第 866 行）；或 (b) 移除 Fixes #10529 关联（以及 (#10529) 提交标题引用），将本改动作为独立消抖提交，其证据即 E2E 报告中已有的本地复现。
对心跳测试的任何消抖都必须保持 issue #10529 的 E2E 报告所述标准——"不删除、不放宽、不重试任何断言"：只允许改变时间预算，不能改变子测试所观测的内容（来源：issue #10529 的 E2E 报告评论 5465732753，"应用的修复"一节；PR 正文亦有相同表述）。若选择重新对准，验收标准是 stamps each tick in flight around the gh call and clears it after 子测试在 CI 中通过——请通过再次放宽新容忍度并确认该子测试变红来证明修复有效。

Disposition: escalated to a maintainer — the round-3 re-verification was independently confirmed this round; still not implementable by this bot, so this thread stays open.
Re-verified against HEAD 9da972231d — the exact commit your ledger assessed:
git diff origin/main...HEADis still only the acp-bridge timeout raise (+4/−1 inpackages/acp-bridge/src/json-string-bytes.test.ts);git diff 02f2101f4305..HEAD -- .github/scripts/is empty;- the failing subtest sits at
.github/scripts/autofix-status-heartbeat.test.mjs:866, its error string at line 887 — an 8swaitForbudget for two stamped gh calls at a 1s tick, i.e. a load-sensitive timing budget of exactly the kind the issue's deflake standard permits changing; - new evidence this round: this PR's own CI at this HEAD (run 33299855286) shows the sickness Main CI failed: Qwen Code CI on 02f2101f4305 #10529 records is still live — the
Testjob died at its 60-minute cap (timeout-minutes: 60on the ci.yml test job; the job ran 61m06s and concluded CANCELLED) with no test result, andPost Coverage Commentfailed on the missing artifact 4 seconds later. The acp-bridge 60s ceiling can neither cause nor cure a 60-minute lane death (it adds at most 55s to one test), confirming the recorded failure's cause lies elsewhere.
Why neither remediation changed status this round:
- Retarget (option a) — the heartbeat deflake lives in
.github/scripts/, a protected area for this bot, and the deterministic footprint gate rejects rounds expanding outside this PR'spackages/acp-bridgefootprint; feedback requesting such a change is escalated, not implemented. Your acceptance criterion (relax the new tolerance again and watch the subtest go red) is recorded with the deferred work item for whoever performs that deflake. - Unlink (option b) — re-verified from the workflow source this round: the address-review path has no PR-body/title edit mechanism (no
gh pr editanywhere in qwen-autofix.yml;pr-body.mdis consumed only at PR creation), and the(#10529)title reference sits in already-pushed commita623924a80while this loop is additive-commits-only.
Question for the maintainer (unanswered since round 1): repair the false linkage by (a, recommended) editing the PR body to drop Fixes #10529 and merging this as a standalone deflake (evidence: the E2E report's local reproduction; the touched test was re-verified green at this HEAD — 5/5), leaving #10529 open, or (b) closing this PR and deflaking the heartbeat suite under #10529 as maintainer-owned work. The heartbeat deflake is tracked in the deferred-findings queue either way. The lane-health signal above (the vitest lane dying at its 60-minute cap on this very HEAD) may deserve a separate look.

处置：升级给维护者——第 3 轮的复核本轮已独立确认；本机器人仍无法实施，线程保持打开。
已在 HEAD 9da972231d 上复核——与你的账目所评估的提交完全一致：
git diff origin/main...HEAD仍然只是 acp-bridge 的超时上调（packages/acp-bridge/src/json-string-bytes.test.ts中 +4/−1）；git diff 02f2101f4305..HEAD -- .github/scripts/为空；- 失败子测试位于
.github/scripts/autofix-status-heartbeat.test.mjs:866，其错误字符串在第 887 行——在 1 秒 tick 下用 8 秒waitFor预算等待两次带戳记的 gh 调用，即正是 issue 消抖标准允许调整的那类负载敏感时间预算； - 本轮新证据： 本 PR 自己在该 HEAD 上的 CI（运行 33299855286）显示 Main CI failed: Qwen Code CI on 02f2101f4305 #10529 记录的病症仍然存活——
Test任务死于其 60 分钟上限（ci.yml 中 test 任务的timeout-minutes: 60；该任务运行 61 分 06 秒，结论 CANCELLED），未上报任何测试结果；Post Coverage Comment在 4 秒后因缺失工件而失败。acp-bridge 的 60 秒上限既不会造成也不会治愈一个 60 分钟的通道死亡（它最多给一个测试增加 55 秒），这证实所记录失败的根因在别处。
本轮两种补救方式状态不变的原因：
- 重新对准（方案 a）——心跳消抖位于
.github/scripts/，对本机器人是受保护区域，且确定性足迹门禁会拒绝扩展到本 PRpackages/acp-bridge足迹之外的轮次；要求此类变更的反馈一律升级，不实施。你给出的验收标准（再次放宽新容忍度并确认子测试变红）已随延迟工作项一并记录，供执行该消抖的一方使用。 - 解除关联（方案 b）——本轮已从 workflow 源码再次核实：address-review 路径没有任何修改 PR 正文/标题的机制（qwen-autofix.yml 中不存在任何
gh pr edit；pr-body.md只在创建 PR 时被消费），且标题中的(#10529)引用位于已推送的提交a623924a80，而本循环只允许追加式提交。
请维护者决策（自第 1 轮起未获答复）： 以如下方式修复错误关联——（a，推荐）编辑 PR 正文移除 Fixes #10529，将本 PR 作为独立消抖合并（证据：E2E 报告中的本地复现；被触碰测试已在本 HEAD 复核为绿——5/5），让 #10529 保持打开；或（b）关闭本 PR，在 #10529 下由维护者亲自为心跳套件消抖。无论哪种，心跳消抖都已记录在 deferred-findings 队列中。上面的通道健康信号（vitest 通道恰恰在本 HEAD 上死于 60 分钟上限）或许值得单独关注。

[Critical] R1-1: [certifies-falsely] [new-surface] This PR claims to fix issue (10529) (Fixes #10529, branch autofix/issue-10529, commit title (#10529)), but the failure recorded in that issue happened in a different test that this PR never touches — and the acp-bridge vitest suite never even ran in the referenced CI run. Round 4: still stands — independently re-verified this round against the raw job log of run 33274358974, which proves the opposite attribution.
Issue (10529) records CI run 33274358974 (job 99165081177). That job failed at the Run .github/scripts helper tests step: not ok 17 - autofix-status-heartbeat loop, failing subtest stamps each tick in flight around the gh call and clears it after with error expected at least two PATCH calls with stamp observations, TAP summary # tests 489 / # pass 488 / # fail 1, exit code 1. The job ended at that step, so the Run tests and generate reports step — the vitest step that executes this PR's deflaked test — was skipped entirely. Zero commits between the incident commit 02f2101f4305 and this PR's HEAD touch the heartbeat suite (git log 02f2101f4305..HEAD -- .github/scripts/ is empty), so merging auto-closes the tracking issue while the failure it records remains live in the tree: the next main push under comparable load fails the same heartbeat subtest at the same step, the vitest step is again never reached, and main CI goes red with its tracking issue already closed.
The timeout raise itself is a legitimate deflake of a real, separately evidenced flake — the local reproduction in the E2E report (Test timed out in 5000ms on unmodified main, mutation probe under load) is undisputed. The defect is exclusively the Fixes #10529 certification.
Witness:
gh run view 33274358974 --json jobs:

step `Run tests and generate reports` conclusion: skipped

PR body: "attribution of run 33274358974 to this exact test is inferred from local reproduction, not proven from the run itself"
Either retarget the autofix at the test that actually failed — deflake the autofix-status-heartbeat loop suite in .github/scripts/autofix-status-heartbeat.test.mjs (failing subtest stamps each tick in flight around the gh call and clears it after, line 866 at HEAD) — or drop the Fixes #10529 linkage and the (#10529) commit-title reference, and ship this as a standalone deflake whose evidence is the local reproduction already in the E2E report. This decision has been escalated to a maintainer since round 1 and remains unanswered.
Any deflake of the heartbeat test must keep the deflake standard the issue's E2E report quotes — "no assertion removed, weakened, or retried" (source: E2E report comment 5465732753, "Fix applied" section): it may only change the timing budget (the 8000 argument of waitFor at .github/scripts/autofix-status-heartbeat.test.mjs:883), not what the subtest observes.
For the retarget option, the acceptance criterion is that the stamps each tick in flight around the gh call and clears it after subtest goes red again when the widened tolerance is relaxed — please prove the fix with that mutation (the unlink option is PR metadata and no test can pin it).
中文说明
本 PR 声称修复 issue (10529)（Fixes #10529、分支 autofix/issue-10529、提交标题 (#10529)），但该 issue 记录的失败发生在本 PR 从未触碰的另一个测试中——而且在被引用的 CI 运行中，acp-bridge 的 vitest 套件根本没有执行。第 4 轮：仍然成立——本轮已对照 run 33274358974 的原始任务日志独立复核，该日志证明的归因与 PR 的归因相反。
Issue (10529) 记录的是 CI 运行 33274358974（job 99165081177）。该任务在 Run .github/scripts helper tests 步骤失败：not ok 17 - autofix-status-heartbeat loop，失败子测试 stamps each tick in flight around the gh call and clears it after，错误 expected at least two PATCH calls with stamp observations，TAP 汇总 # tests 489 / # pass 488 / # fail 1，退出码 1。任务在该步骤终止，因此本应执行 vitest（即本 PR 消抖测试所在步骤）的 Run tests and generate reports 被完全跳过。从事故提交 02f2101f4305 到本 PR HEAD 之间没有任何提交触碰该心跳套件（git log 02f2101f4305..HEAD -- .github/scripts/ 为空），因此按当前提交合并会自动关闭追踪 issue，而该 issue 记录的失败仍然留在代码树中：下一次在相近负载下推送 main 会在同一步骤失败于同一个心跳子测试，vitest 步骤再次无法执行，main CI 再次变红而其追踪 issue 已被关闭。
超时上调本身是对一个真实存在、另有独立证据的抖动的合理消抖——E2E 报告中的本地复现（未改动 main 上 Test timed out in 5000ms、负载下的变异探针）没有争议。缺陷仅在于 Fixes #10529 这一认证。
修复方式二选一：将 autofix 重新对准实际失败的测试——对 .github/scripts/autofix-status-heartbeat.test.mjs 中的 autofix-status-heartbeat loop 套件做消抖（失败子测试 stamps each tick in flight around the gh call and clears it after，HEAD 上位于第 866 行）；或者移除 Fixes #10529 关联与 (#10529) 引用，将本改动作为独立消抖提交，其证据即 E2E 报告中已有的本地复现。该决策自第 1 轮起已升级给维护者，至今未获答复。
对心跳测试的任何消抖都必须保持该 issue E2E 报告引用的消抖标准——"不删除、不放宽、不重试任何断言"（来源：E2E 报告评论 5465732753，"应用的修复"一节）：修复只能改变时间预算（.github/scripts/autofix-status-heartbeat.test.mjs:883 处 waitFor 的 8000 参数），不能改变子测试所观测的内容。
若选择重新对准，验收标准是 stamps each tick in flight around the gh call and clears it after 子测试在再次放宽容忍度时重新变红——请通过该变异证明修复有效（解除关联选项属于 PR 元数据，无法用测试固定）。

Round 4: re-verified at HEAD ed03500c5c — the finding still stands and stays escalated to a maintainer; this thread is deliberately left open.
Verified at this HEAD:
git diff origin/main...HEADstill touches exactly one file,packages/acp-bridge/src/json-string-bytes.test.ts(+4/−1, a timeout ceiling raise only).- The heartbeat suite is unchanged since the incident:
git log 02f2101f4305..HEAD -- .github/scripts/autofix-status-heartbeat.test.mjsis empty, and the file's last change (6cd0cc7869) is an ancestor of the incident commit. The cited subtest is still at line 866, thewaitFor(..., 8000)budget at line 883, the assertionexpected at least two PATCH calls with stamp observationsat line 887. - One witness in the round-4 restatement is stale at this HEAD (which merged main):
git log 02f2101f4305..HEAD -- .github/scripts/is no longer empty — ci: stabilize tests under shared ECS host contention #10552, ci: update qwen on third Hong Kong ECS host #10541, ci: gate heavy jobs on a disk floor and persist pressure samples #10394 touched other files in that directory (web-shell-visuals-publish.test.mjs,check-disk-floor.*). None touched the heartbeat suite, so the substance is unchanged.
New CI evidence: run 33321057659, Test (ubuntu-latest, Node 22.x) concluded FAILURE at ~31 min (16:13:35Z → 16:44:14Z) — a hard failure, not the 60-minute cancellation the prior round recorded. Per ci.yml, that job runs the .github/scripts helper tests (including this suite) before vitest. This agent holds no GitHub credentials (gh auth status: not logged in), so it cannot confirm the failing step from the job log; local baseline probes: heartbeat suite 29/29 pass unloaded, touched test 5/5, acp-bridge package 1818/1818.
Why nothing was implemented: both remediations remain outside this loop's reach. Option A (retarget: deflake the heartbeat suite) lives in the protected .github/scripts/ area — the address-review boundary forbids it and the deterministic footprint gate rejects rounds expanding outside this PR's packages/acp-bridge footprint. Option B (unlink) requires editing the PR body and rewriting an already-pushed commit title; this path has no PR-body edit mechanism and is additive-commits-only. The decision requested from a maintainer since round 1 — (recommended) unlink Fixes #10529 and merge the standalone deflake, or close this PR and deflake the heartbeat suite as maintainer-owned work — remains open.

第 4 轮：已在 HEAD ed03500c5c 复核——该发现仍然成立，继续升级给维护者；本线程有意保持打开。
在当前 HEAD 上核实：
git diff origin/main...HEAD仍然只触碰一个文件packages/acp-bridge/src/json-string-bytes.test.ts（+4/−1，仅为上调超时上限）。- 心跳套件自事故以来未变：
git log 02f2101f4305..HEAD -- .github/scripts/autofix-status-heartbeat.test.mjs为空，且该文件最后一次变更（6cd0cc7869）是事故提交的祖先。被引用的子测试仍位于第 866 行，waitFor(..., 8000)时间预算在第 883 行，断言expected at least two PATCH calls with stamp observations在第 887 行。 - 第 4 轮复述中的一条证据在当前 HEAD（已合并 main）上已过时：
git log 02f2101f4305..HEAD -- .github/scripts/不再为空——ci: stabilize tests under shared ECS host contention #10552、ci: update qwen on third Hong Kong ECS host #10541、ci: gate heavy jobs on a disk floor and persist pressure samples #10394 触碰了该目录下的其他文件（web-shell-visuals-publish.test.mjs、check-disk-floor.*），但均未触碰心跳套件，实质结论不变。
新的 CI 证据： run 33321057659 中 Test (ubuntu-latest, Node 22.x) 在约 31 分钟时以 FAILURE 结束（16:13:35Z → 16:44:14Z）——是硬性失败，而非上一轮记录到的 60 分钟超时取消。按 ci.yml，该任务会先运行 .github/scripts 辅助测试（含本套件）再运行 vitest。本代理没有 GitHub 凭据（gh auth status：未登录），无法通过任务日志确认失败步骤；本地基线探针：心跳套件无负载下 29/29 通过，被触碰测试 5/5 通过，acp-bridge 包 1818/1818 通过。
未实施任何修改的原因： 两种补救方式都超出本循环的能力范围。方案 A（重新对准：为心跳套件消抖）位于受保护的 .github/scripts/ 区域——address-review 边界禁止修改，且确定性足迹门禁会拒绝扩展到本 PR packages/acp-bridge 足迹之外的回合。方案 B（解除关联）需要编辑 PR 正文并重写已推送的提交标题；本路径没有 PR 正文编辑机制，且只允许增量提交。自第 1 轮起请求维护者作出的决策——（推荐）解除 Fixes #10529 关联并以独立消抖合并本 PR，或关闭本 PR、由维护者自行为心跳套件消抖——仍然悬而未决。

Issue (10529) records CI run 33274358974 (job 99165081177). That job failed at step 33 Run .github/scripts helper tests: not ok 17 - autofix-status-heartbeat loop, failing subtest stamps each tick in flight around the gh call and clears it after with error expected at least two PATCH calls with stamp observations (suite duration 52.7s), TAP summary # tests 489 / # pass 488 / # fail 1, exit code 1. The job halted there, so step 35 Run tests and generate reports — the vitest step that executes this PR's deflaked test — was skipped entirely: the new 60s ceiling was never executed in the incident this PR claims to fix. The heartbeat suite is byte-identical to the incident commit (git diff 02f2101f43..HEAD -- .github/scripts/autofix-status-heartbeat.test.mjs is empty), so the next main push under comparable load fails the same subtest at the same step, the vitest step is again never reached, and main CI goes red with its tracking issue already auto-closed.

Either retarget the autofix at the test that actually failed — deflake the autofix-status-heartbeat loop suite in .github/scripts/autofix-status-heartbeat.test.mjs (failing subtest at line 866) — or drop the Fixes #10529 linkage and the (#10529) commit-title reference, and ship this as a standalone deflake whose evidence is the local reproduction already in the E2E report.

PR body: Fixes #10529
The deflake standard the issue's own E2E report quotes — "no assertion removed, weakened, or retried" (E2E report on issue (10529), "Fix applied" section) — binds any retargeted deflake: change only the timing budget or scheduling tolerance, never what the subtest observes. The acceptance criterion is the autofix-status-heartbeat loop suite — specifically the stamps each tick in flight around the gh call and clears it after subtest — passing in CI; please prove the fix by relaxing the new tolerance again and confirming that subtest goes red.
中文说明
本 PR 声称修复 issue (10529)（Fixes #10529、分支 autofix/issue-10529、提交标题 (#10529)），但该 issue 记录的失败发生在本 PR 从未触碰的另一个测试中——而且在被引用的 CI 运行中，acp-bridge 的 vitest 套件根本没有执行。第 5 轮：仍然成立——本轮已对照 run 33274358974 的原始任务日志与本 HEAD 的代码独立复核。
Issue (10529) 记录的是 CI 运行 33274358974（job 99165081177）。该任务在步骤 33 Run .github/scripts helper tests 失败：not ok 17 - autofix-status-heartbeat loop，失败子测试 stamps each tick in flight around the gh call and clears it after，错误 expected at least two PATCH calls with stamp observations（套件耗时 52.7 秒），TAP 汇总 # tests 489 / # pass 488 / # fail 1，退出码 1。任务在该步骤终止，因此步骤 35 Run tests and generate reports——即执行本 PR 消抖测试的 vitest 步骤——被完全跳过：本 PR 声称修复的事故中，新的 60 秒上限根本没有被执行。该心跳套件与事故提交逐字节一致（git diff 02f2101f43..HEAD -- .github/scripts/autofix-status-heartbeat.test.mjs 为空），因此下一次在相近负载下推送 main 会在同一步骤失败于同一个子测试，vitest 步骤再次无法执行，main CI 再次变红而其追踪 issue 已被自动关闭。
超时上调本身是对一个真实存在、另有独立证据的抖动的合理消抖——E2E 报告中的本地复现没有争议。缺陷仅在于 Fixes #10529 这一认证。请将 autofix 重新对准实际失败的测试——对 .github/scripts/autofix-status-heartbeat.test.mjs 中的 autofix-status-heartbeat loop 套件做消抖（失败子测试位于第 866 行）；或者移除 Fixes #10529 关联与 (#10529) 引用，将本改动作为独立消抖提交，其证据即 E2E 报告中已有的本地复现。
对心跳测试的任何消抖都必须保持该 issue E2E 报告引用的消抖标准——"不删除、不放宽、不重试任何断言"（issue (10529) 的 E2E 报告"应用的修复"一节）：修复只能改变时间预算或调度容忍度，不能改变子测试所观测的内容。验收标准是 autofix-status-heartbeat loop 套件——特别是 stamps each tick in flight around the gh call and clears it after 子测试——在 CI 中通过；请通过再次放宽新设置的容忍度并确认该子测试变红来证明修复有效。

Disposition: escalated to a maintainer — the round-5 re-verification was independently confirmed at the exact HEAD your ledger assessed; still not implementable by this bot, so this thread stays open.
Re-verified against HEAD ccbcde476d:
git diff origin/main...HEADstill touches exactly one file,packages/acp-bridge/src/json-string-bytes.test.ts(+4/−1, a timeout ceiling raise only).- The heartbeat suite is byte-identical to the incident commit:
git diff 02f2101f43..HEAD -- .github/scripts/autofix-status-heartbeat.test.mjsis empty; the file's last change (6cd0cc7869) is an ancestor of02f2101f43. The cited subtest is still at line 866, thewaitFor(..., 8000)budget at line 883, the assertionexpected at least two PATCH calls with stamp observationsat line 887. ci.ymlstill runs the helper tests (line 584) before the vitest step (line 637) in the same job, so the incident shape — vitest skipped after the heartbeat failure — reproduces on the next comparable-load main push.
New CI evidence this round: at this HEAD, run 33328773311's Test (ubuntu-latest, Node 22.x) concluded SUCCESS — the lane that runs the heartbeat suite and then vitest passed, evidencing the recorded flake is intermittent/load-dependent (failed the incident run under contention; passes this run and unloaded local runs — heartbeat suite 29/29, touched test 5/5 this round). The same run's Integration Tests (no-AK, No Sandbox) FAILURE (~56 min) and web-shell E2E Smoke CANCELLED have no causal path from this diff: the integration job's commands (typecheck:integration + an explicit no-AK suite list) never import this unit test file, and the duration matches the documented ECS-contention shape (install >30 min + the step's 20-minute cap; #10552/#10556 are main's own stabilizations for that class). Job logs remain unreadable from here (gh auth status: not logged in).
Why nothing was implemented: both remediations remain outside this loop's reach. Option A (retarget: deflake the heartbeat suite) lives in the protected .github/scripts/ area — the address-review boundary forbids modifying CI/autofix-loop machinery the PR was not already about, and the deterministic footprint gate rejects rounds expanding outside this PR's packages/acp-bridge footprint. Option B (unlink) requires editing the PR body and rewriting an already-pushed commit title; re-verified from qwen-autofix.yml this round: no gh pr edit exists, pr-title.txt/pr-body.md are consumed only at PR creation, and this loop is additive-commits-only.
Question for the maintainer (unanswered since round 1): repair the false linkage by (a, recommended) editing the PR body to drop Fixes #10529 and merging this as a standalone deflake (evidence: the E2E report's local reproduction; the PR body already carries the caveat that the run's logs were then unreadable), leaving #10529 open to track the heartbeat failure — or (b) closing this PR and deflaking the heartbeat suite under #10529 as maintainer-owned work (timing budget only; no assertion removed, weakened, or retried; acceptance criterion: relax the new tolerance again and confirm the subtest goes red). The heartbeat deflake is re-recorded in the deferred-findings queue this round so it survives merge either way.
中文说明
处置：升级给维护者——第 5 轮的复核已在你们的台账所评估的确切 HEAD 上独立确认；本机器人仍然无法实施，因此本线程保持打开。
已在 HEAD ccbcde476d 上复核：
git diff origin/main...HEAD仍然只触碰一个文件packages/acp-bridge/src/json-string-bytes.test.ts（+4/−1，仅提高超时上限）。- 心跳套件与事故提交逐字节一致：
git diff 02f2101f43..HEAD -- .github/scripts/autofix-status-heartbeat.test.mjs为空；该文件最后一次修改（6cd0cc7869）是02f2101f43的祖先。被引用的子测试仍在第 866 行，waitFor(..., 8000)预算在第 883 行，断言expected at least two PATCH calls with stamp observations在第 887 行。 ci.yml仍在同一 job 中先运行 helper 测试（第 584 行）、后运行 vitest 步骤（第 637 行），因此事故形态——心跳失败后 vitest 被跳过——会在下一次相近负载的 main 推送中复现。
本轮新的 CI 证据： 在本 HEAD 上，运行 33328773311 的 Test (ubuntu-latest, Node 22.x) 结论为 SUCCESS——运行心跳套件再运行 vitest 的通道通过了，证明所记录的抖动是间歇性/负载相关的（在事故运行中因争用而失败；本次运行及本机无负载运行通过——本轮心跳套件 29/29、被触碰测试 5/5）。同一运行的 Integration Tests (no-AK, No Sandbox) FAILURE（约 56 分钟）与 web-shell E2E Smoke CANCELLED 与本差异无因果路径：集成 job 的命令（typecheck:integration + 明确的 no-AK 套件列表）从不导入这个单元测试文件，且耗时符合已记录的 ECS 争用形态（安装超过 30 分钟 + 步骤自身的 20 分钟上限；#10552/#10556 正是 main 针对该类别的稳定性修复）。从这里仍无法读取 job 日志（gh auth status：未登录）。
为何未实施任何修改： 两种补救方式仍然都在本循环的能力之外。方案 A（重新对准：为心跳套件消抖）位于受保护的 .github/scripts/ 区域——address-review 边界禁止修改本 PR 原本并不涉及的 CI/autofix 循环机制，且确定性足迹门会拒绝扩展到本 PR packages/acp-bridge 足迹之外的回合。方案 B（解除关联）需要编辑 PR 正文并改写已推送提交的标题；本轮再次从 qwen-autofix.yml 核实：不存在 gh pr edit，pr-title.txt/pr-body.md 仅在创建 PR 时使用，且本循环只允许增量提交。
给维护者的问题（自第 1 轮起未获答复）： 请以以下方式之一修复错误关联：(a，推荐) 编辑 PR 正文移除 Fixes #10529，将本 PR 作为独立消抖合入（证据：E2E 报告中的本地复现；PR 正文已载有当时无法读取运行日志的声明），让 #10529 保持打开以跟踪心跳失败；或 (b) 关闭本 PR，在 #10529 下以维护者主导的工作为心跳套件消抖（只改时间预算；不删除、不放宽、不重试任何断言；验收标准：再次放宽容忍度并确认该子测试变红）。本轮已重新将心跳消抖记录到 deferred-findings 队列，无论合入与否都不会丢失。

Partially reviewed — gaps disclosed.
1 Suggestion-level finding(s) this review confirmed are already reported on this PR and are not repeated:
- D15-2 unbounded mismatch collector — already reported (round-14 deferral D14-1, review 5087368084)
Not reviewed: reverse audit — stopped before round 1 by the review time budget.
Test Plan (not a blocker): 5 tests passing — this review observed 1912, 27957, 298, 1755, 504, 5659, 94 passed.
Deferred under the convergence posture (round 15, not a blocker) — recorded, not requested in this round:
packages/acp-bridge/src/json-string-bytes.test.ts:16 — [review] PR body, Test Plan, Evidence and Risk describe the superseded timeout raise
Residual risk: this loop is persistently critical — Criticals stood in the previous round's work-list and stand again this round (1 Critical(s)), the rate of first-time findings is not falling (this round 0, previous 0), and the standing Critical backlog is not shrinking. The severity floor will not converge it. Recommendation: land-with-residual-risk — the exit is a maintainer risk-acceptance decision (merge, carrying the residual risk), not another review round. Residual-risk inventory for that decision (maintainer to complete):

[Critical] R12-1: [certifies-falsely] [new-surface] This PR still certifies Fixes #10529 (body sections "Linked Issues" and "关联 Issue", title fix(acp-bridge): deflake the exhaustive UTF-16 byte-estimate test (#10529), branch autofix/issue-10529), but the failure issue (10529) records happened in a suite this PR never touches — the autofix-status-heartbeat loop subtest in .github/scripts/autofix-status-heartbeat.test.mjs — and in run 33274358974 the step that executes the acp-bridge vitest suite was skipped, so the changed test never ran. Round 15: still stands, re-verified this round against the raw job log and the live PR and issue state at HEAD 4c06d54e. The code change is not alleged to be wrong; the defect is the certification.
Failure scenario: replaying the issue's own incident against this tree changes no step outcome. Run .github/scripts helper tests (.github/workflows/ci.yml:595-597, no continue-on-error) runs the heartbeat suite, which is byte-identical to the incident commit because git diff cd1ac728..HEAD -- .github/ is empty; when its stamps each tick in flight around the gh call and clears it after subtest flakes under contention the step exits 1, and Run tests and generate reports (.github/workflows/ci.yml:648-650) carries no always(), so the only step that would execute this test is skipped and the run goes red before any test result is reported — the exact recorded shape. Merging therefore puts a permanent attribution on the record: the merge commit and changelog credit an acp-bridge test change with closing an issue whose recorded failure was an unrelated helper-suite flake, and anyone later bisecting a repeat heartbeat failure finds its tracking issue closed against a fix that never addressed it. Issue (10529) is already CLOSED as stale with the heartbeat flake named as its cause, so the linkage no longer has an auto-close left to justify it.
The reviewed file is byte-identical to what round 14 reviewed — git diff 323281f5..HEAD -- packages/acp-bridge/src/json-string-bytes.test.ts is empty — so nothing since the last round could have closed this.

Suggested fix: this is PR metadata rather than code, and the author bot has already requested it of a maintainer (comment 3910803244) because it cannot perform it itself. Before merge, drop Fixes #10529 from both body sections and replace it with a plain non-closing reference recording that issue (10529) was closed as stale and its failure was the unrelated .github/scripts heartbeat flake; and drop (#10529) from the title, for example test(acp-bridge): deflake the exhaustive UTF-16 byte-estimate sweep. The code needs no edit — the maintainer's own verification report reaches the same split: "merge the code change, but drop or downgrade the Fixes #10529 link first".
Dropping the link must not leave the recorded failure untracked: it is already carried by OPEN issue (10547), item rc:3888574016 .github/scripts/autofix-status-heartbeat.test.mjs, whose deflake is maintainer-owned — and the closing keyword must not be re-pointed at (10547) either, since that issue is a deferred-findings ledger rather than this PR's scope.
中文说明
本 PR 仍然声明 Fixes #10529（正文的 "Linked Issues" 与 "关联 Issue" 两节、标题 fix(acp-bridge): deflake the exhaustive UTF-16 byte-estimate test (#10529)、分支 autofix/issue-10529），但 issue (10529) 所记录的失败发生在本 PR 从未触碰的另一个套件中——.github/scripts/autofix-status-heartbeat.test.mjs 里的 autofix-status-heartbeat loop 子测试——并且在 run 33274358974 中，执行 acp-bridge vitest 套件的步骤被跳过，因此被改动的这个测试根本没有运行过。第 15 轮：仍然成立，本轮已对照原始任务日志以及 HEAD 4c06d54e 上的实时 PR 与 issue 状态重新核实。此处并不主张代码改动本身有错；缺陷在于这一认证。
失败场景：把该 issue 自己记录的事故在这棵代码树上重放，没有任何步骤的结果会改变。Run .github/scripts helper tests（.github/workflows/ci.yml:595-597，没有 continue-on-error）运行心跳套件，而该套件与事故提交逐字节相同，因为 git diff cd1ac728..HEAD -- .github/ 为空；当其 stamps each tick in flight around the gh call and clears it after 子测试在争用下抖动时该步骤以 1 退出，而 Run tests and generate reports（.github/workflows/ci.yml:648-650）没有 always()，于是唯一会执行本测试的步骤被跳过，整个运行在上报任何测试结果之前就变红——与记录中的形态完全一致。因此合并会在记录上留下一条永久归因：合并提交与变更日志会把一个 acp-bridge 测试改动记为关闭了某个 issue，而该 issue 记录的失败其实是无关的 helper 套件抖动；日后有人对再次出现的心跳失败做二分定位时，会发现其追踪 issue 已被一个从未处理过它的修复关闭。Issue (10529) 现已以"过期"关闭，并明确将心跳抖动记为原因，因此该关联连"自动关闭"这一理由也已不复存在。
被审查的文件与第 14 轮所审查的逐字节相同——git diff 323281f5..HEAD -- packages/acp-bridge/src/json-string-bytes.test.ts 为空——所以自上一轮以来没有任何改动能使它失效。
证据：见上方英文部分的 Witness 代码块（命令输出为固定格式，未翻译）。要点为：HEAD 上 PR 仍处于 OPEN 且正文两节均含 Fixes #10529；issue (10529) 已 CLOSED（2026-08-31T12:27:02Z），关闭评论指明原因是 .github/scripts helper 测试中的 autofix-status-heartbeat loop 抖动；run 33274358974 的原始日志显示 not ok 17 - autofix-status-heartbeat loop、# fail 1，其中 Test timed out 出现 0 次，json-string-bytes 仅出现在变更文件清单里（标注 unchanged）；该运行的步骤结论为 33 failure（helper tests）、35 skipped（Run tests and generate reports）；.github/ 与被审查测试文件自上一轮以来的 diff 均为空。
建议的修复：这属于 PR 元数据而非代码，作者 bot 已就此向维护者提出请求（评论 3910803244），因为它自己无法执行。合并前请从正文两节中移除 Fixes #10529，改为一条非关闭性的普通引用，说明 issue (10529) 已按过期关闭、其失败是无关的 .github/scripts 心跳抖动；并从标题中移除 (#10529)，例如改为 test(acp-bridge): deflake the exhaustive UTF-16 byte-estimate sweep。代码无需改动——维护者自己的验证报告得出同样的区分："合并代码改动，但先移除或降级 Fixes #10529 关联"。
移除该关联不得使所记录的失败失去追踪：它已由处于 OPEN 状态的 issue (10547) 承载，条目为 rc:3888574016 .github/scripts/autofix-status-heartbeat.test.mjs，其消抖由维护者负责——同时也不要把关闭关键字改为指向 (10547)，因为该 issue 是一个延后发现的清单，不属于本 PR 的范围。

There was a problem hiding this comment.
Disposition: escalated to a maintainer — verified real, and not fixable in code. Re-verified this round at head 5dcf62992c.
The finding is accepted, not disputed. The code carrier was removed in round 13 and stays removed: I re-read the file at this head and it contains no per-test timeout literal (the sweep's it closes on the assertion, with no third argument), so packages/acp-bridge/vitest.config.ts remains authoritative on every lane. This round did not revert or reshape the arm-C structure — the only code change it made is the bounded mismatch report @wenshao recommended in §5 of his verification report, which is a different item.
The two remaining carriers are the PR title ((#10529)) and the PR body (Fixes #10529 in both the "Linked Issues" and "关联 Issue" sections, plus "What this PR does" / Test Plan step 3 / Risk & Scope still describing the withdrawn 60 s timeout raise). Both are GitHub metadata, and this bot has no channel to write them: this path holds no GitHub credentials; pr-title.txt / pr-body.md are consumed only by gh pr create in the develop-issue path (qwen-autofix.yml:1541-1544) — creation, never edit; and gh pr edit occurs zero times in either qwen-autofix.yml or autofix-push-and-report.sh (verified by grep). Adding such a channel would mean editing .github/, which is out of bounds for this bot.
Requested of a maintainer before merge — the exact suggested wording is already in comment 3910803244 and is unchanged: retitle to test(acp-bridge): deflake the exhaustive UTF-16 byte-estimate sweep; replace Fixes #10529 with a plain non-closing reference recording that #10529 was closed as stale and its recorded failure was the unrelated .github/scripts heartbeat flake; and rewrite the body sections around the collect-then-assert-once change instead of the withdrawn 60 s raise. Please do not re-point the closing keyword at #10547 — that is a deferred-findings ledger, not this PR's scope, and the heartbeat flake it tracks is already carried there as item rc:3888574016.
Leaving this thread open until the title/body linkage is dropped.
中文说明
处置：上报维护者——该发现经核实为真，且无法通过代码修复。 本轮已在 head 5dcf62992c 上重新核实。
该发现被接受，没有争议。代码载体已在第 13 轮移除并保持移除：我在当前 head 上重新读取了该文件，其中没有任何 per-test 超时字面量（扫描测试的 it 直接以断言结束，没有第三个参数），因此 packages/acp-bridge/vitest.config.ts 在所有 lane 上仍具权威性。本轮没有回退或重塑「只断言一次」的结构——本轮唯一的代码改动是给不匹配报告加上界，那是 @wenshao 在其验证报告第 5 节中建议的，属于另一件事。
剩余的两个载体是 PR 标题（(#10529)）与 PR 正文（"Linked Issues" 与 "关联 Issue" 两节中的 Fixes #10529，外加 "What this PR does"、Test Plan 第 3 步、Risk & Scope 仍在描述已被撤回的 60 秒超时上调）。两者都是 GitHub 元数据，本机器人没有写入它们的通道：此路径没有 GitHub 凭据；pr-title.txt / pr-body.md 只被 develop-issue 路径中的 gh pr create 消费（qwen-autofix.yml:1541-1544）——只用于创建，从不用于编辑；并且 gh pr edit 在 qwen-autofix.yml 与 autofix-push-and-report.sh 中出现的次数都是零（已用 grep 核实）。而要新增这样一个通道就得改 .github/，那对本机器人来说是越界的。
合入前请求维护者执行——确切的建议措辞已在评论 3910803244 中给出，本轮不变：标题改为 test(acp-bridge): deflake the exhaustive UTF-16 byte-estimate sweep；把 Fixes #10529 换成一条非关闭性的普通引用，说明 #10529 已按过期关闭、其记录的失败是无关的 .github/scripts 心跳抖动；并把正文各节改写为围绕「先收集、只断言一次」的改动，而不是已被撤回的 60 秒上调。请不要把关闭关键字改为指向 #10547——那是一个延后发现的清单，不属于本 PR 的范围，而它所追踪的心跳抖动已作为条目 rc:3888574016 记录在其中。
在标题/正文的关联被移除之前，本线程保持打开。

Qwen Code review timed out. Qwen review timed out after 5400 seconds (of the 90-minute budget). For large PRs, retry with a longer timeout by commenting: |
Maintainer verification report — round 2, at head
|
| probe | result |
|---|---|
| async test, no literal | ❌ Test timed out in 3000ms |
async test, 60_000 literal |
✅ passed at 4501 ms |
The literal really did outrank the operator knob. With it gone, packages/acp-bridge/vitest.config.ts is authoritative for this test again on every lane.
2. The flake is real, still live, and the new fix removes it
Same tree, same box, identical contention, only the test file differs:
Sweeping the contention factor, and rerunning each cell 8 times:
| K | oversubscription | base (main) | PR #10532 |
|---|---|---|---|
| 0 | 1× | 475 ms pass | 61 ms pass |
| 4 | 5× | 2298 ms pass | 269 ms pass |
| 8 | 9× | 4119 ms pass — 82 % of budget | 470 ms pass |
| 10 | 11× | 5191 ms, Test timed out in 5000ms |
584 ms pass |
| 40 | 41× | (already red) | 2140 ms pass |
| 80 | 81× | (already red) | 4280 ms pass |
Repeat stability, 8 consecutive runs per cell: at 9× the base arm is 0/8 red but burning 87 % of the budget; at 11× it is 7/8 red. The PR arm is 0/8 red in both, at 453–597 ms. Base crosses the 5 s budget at ~11× oversubscription; the PR arm extrapolates to ~95× — roughly 8.7× more headroom. The raw sweep with no expect() at all costs 14 ms: ~87 % of the base arm's measured time is the 65,536 expect() calls, and ~97 % of it is not the function under test.
3. #10552 does not already cover this
packages/acp-bridge/vitest.config.ts raises the ceiling to 60 s only when RUNNER_NAME starts with ecs-qwen-. Holding contention at 11× and changing only RUNNER_NAME:
| arm | RUNNER_NAME |
result | sweep |
|---|---|---|---|
| base | GitHub Actions 7 |
❌ timed out at 5000 ms | 5405 ms |
| base | ecs-qwen-linux-04 |
✅ pass (60 s ceiling) | 5440 ms |
| pr | GitHub Actions 7 |
✅ pass | 558 ms |
| pr | ecs-qwen-linux-04 |
✅ pass | 587 ms |
Real runner names from the API: ecs-qwen-hk1-* / ecs-qwen-hk3-* (Linux ECS) and ecs-qwen-runner-win-hk-* (Windows ECS) all match the prefix; hosted runners are named GitHub Actions <id> and do not. So the lanes still on the 5 s default are the ubuntu-latest fallback (fork PRs, or with the ECS kill-switch on) and macos-latest (merge_group / schedule / dispatch), both of which run npm run test:ci at the repo root. On top of removing the flake there, the change also returns ~410 ms of CPU per suite run everywhere.
4. No loss of detection — this is the part worth checking hardest
V8 coverage of packages/acp-bridge/src/json-string-bytes.ts, per arm:
- statement / branch / function hit maps identical:
true - statements with differing hit counts: 0
- total statement hits: 2,108,931 on base, 2,108,931 on the PR
Not "same percentage" — the same per-statement execution counts. The loop still evaluates both sides for all 65,536 code units; only the assertion call is hoisted out.
Mutating the production file, one mutation at a time, and running both arms:
| mutation | mismatching code units | base | PR |
|---|---|---|---|
lone surrogate 6 → 3 bytes |
1024 | ❌ | ❌ killed |
drop 0x08 from the short-escape set |
1 | ❌ | ❌ killed |
fast path return b → return b + 1 |
63454 | ❌ | ❌ killed |
code <= 0x7f → 0x7e |
0 | ✅ | ✅ equivalent |
3/3 non-equivalent mutants killed on both arms. The last one is equivalent because 0x7f never reaches the slow path — for single-code-unit inputs only 2082 of 65536 (3.2 %) get past the no-escape fast-path regex at all. That is a pre-existing property of this test, identical on both arms, and not something this PR changes; I mention it only so the "exhaustive" framing is not over-read.
The batched form is also more informative on failure: it reports the offending code, where the per-iteration form printed only expected 5 to be 8.
5. Non-blocking, but worth folding in: the collector is unbounded
expect(mismatches).toEqual([]) serialises every mismatch into the CI log. Measured on the same three mutations:
| mutation | base output | PR output |
|---|---|---|
| 1 mismatch | 3.2 kB / 78 lines | 3.2 kB / 84 lines |
| 1024 | 3.2 kB / 78 lines | 123 kB / 5199 lines |
| 63454 | 3.2 kB / 78 lines | 7.4 MB / 317,349 lines |
A broken fast path is exactly the regression class this test exists to catch, and it is the case that produces the 7.4 MB dump. This is the same thing the review bot has been carrying as a deferral; here is the number behind it. Bounding the report keeps every benefit above:
expect({ count: mismatches.length, first: mismatches.slice(0, 5) }).toEqual({
count: 0,
first: [],
});I ran that variant against the 63,454-mismatch mutation: it fails with 4.0 kB / 108 lines, still naming the exact count and the first offending code points. Your call whether it lands here or as a follow-up — it does not block the merge.
6. The body is now the blocker, not the code
- The PR body describes a fix that is no longer in the diff. "Raises the per-test timeout … to an explicit 60s"; Test Plan step 3 asks the reviewer to "confirm the diff is exactly one timeout argument plus a short comment"; the Risk section discusses a 60 s report delay. None of that is true at this head. All three triage stages also reviewed the superseded approach — stage 2 explicitly reasoned that batching "changes the test's failure shape and is a bigger edit than the problem asks for", which is the approach now shipped.
Fixes #10529is still wrong, and I re-confirmed it from the run's own step data rather than inference: in run 33274358974 (jobTest (ubuntu-latest, Node 22.x)onecs-qwen-runner-64c-7), step 33Run .github/scripts helper testsfailed and step 35Run tests and generate reports— the only step that executesnpm run test:ci— was skipped. The acp-bridge suite never ran. Issue Main CI failed: Qwen Code CI on 02f2101f4305 #10529 has been closed since 2026-08-31 for that unrelated helper-test failure. Merging with the link re-closes a closed issue against a false cause.
7. Red check is unrelated
Test (ubuntu-latest, Node 22.x) (run 33622567465, on ecs-qwen-hk4-13): 56871 passed, 3 failed — hook-runner.process.test.ts and recall-scan-latency.test.ts in packages/core, MessageList.dom.test.tsx in packages/web-shell. None in packages/acp-bridge, the only package this PR touches. Both core tests pass locally on the base tree (21/21), and recall-scan-latency reproduces here purely as a load flake — expected 80.65542499999901 to be less than 50 under the same contention harness. Same class of problem as this PR, different test.
8. Regression check
Full packages/acp-bridge suite, both arms, after building packages/core in each: 34 files, 1914 tests, all passed on base and on the PR. eslint --max-warnings 0, prettier --check and tsc --noEmit are clean on the changed file.
Recommendation
- Before merge (bookkeeping): rewrite "What this PR does", "Reviewer Test Plan", "Evidence" and "Risk & Scope" around the assert-once change, and drop
Fixes #10529(a plain reference is fine). - Then merge. The change is causally load-bearing on the hosted lanes, provably equivalent in what it exercises, kills the same mutants, restores the ci: stabilize tests under shared ECS host contention #10552 knob, and is faster everywhere.
- Optional, now or as a follow-up: bound the mismatch report as in §5.
中文说明
维护者验证报告 —— 第 2 轮，基于 head 049ef405
在我第 1 轮报告（comment 5503235459，针对 8cae3ac8）之后，修复方案已经换掉了。 提交 3f56e9a8 用我当时推荐的"只断言一次"改写替换了 60 秒超时上调。我从零重建了验证环境，针对新 head 重新验证，没有沿用任何旧结论。
结论：代码可以合入——它严格优于第 1 轮所审的版本——但请先重写 PR 描述。 描述、Test Plan、Evidence、Risk 各节仍然在讲那个已被替换的超时上调，且 Fixes #10529 依然是错的。另有一条非阻塞的跟进建议，值得顺手一起做（见第 5 节）。
方法。 Linux 6.12，16 核，29 GB；Node 22.22.2，vitest 3.2.7。三个 worktree：base = merge-base 29baecd7，pr = head 049ef405，old = 把 a623924a 的测试文件放回 head。git diff --stat 29baecd7 pr10532 恰好是 1 file changed, 5 insertions(+), 3 deletions(-)——两臂除此之外完全相同。依赖用逐条软链从一个已构建的兄弟检出接过来（不是全新 npm ci）；packages/core 在每个臂里各自构建。争用用 taskset -c 0 加 K 个忙循环制造，因此 "K" 表示单核 (K+1) 倍超订。绝对毫秒来自这台机器而非 ECS 宿主——机理可迁移，数值不可。
1. 采纳的 diff 就是上一轮推荐的写法，逐字一致
归一化空白后，新的测试体与第 1 轮 "arm C" 片段逐字符相同，且文件中已没有任何 per-test 超时字面量（grep -c '60_000'：被替换的 a623924a → 1，本 head → 0）。
这解决了第 1 轮提出的那个真实权衡：per-test 字面量会压过 #10552 引入的套件级 testTimeout 旋钮。这里把配置上限设为 3000 ms、RUNNER_NAME=ecs-qwen-* 重新探测：
| 探针 | 结果 |
|---|---|
| 异步测试，无字面量 | ❌ Test timed out in 3000ms |
异步测试，带 60_000 字面量 |
✅ 4501 ms 通过 |
字面量确实压过了运维旋钮。去掉之后，packages/acp-bridge/vitest.config.ts 在所有 lane 上重新对这个测试具有权威性。
2. 抖动是真的、目前仍然存在，新修复消除了它
同一棵树、同一台机器、同样争用，只有测试文件不同（见上方英文部分第一张图）。
扫描争用因子，并对每格重跑 8 次：
| K | 超订倍数 | base（main） | PR #10532 |
|---|---|---|---|
| 0 | 1× | 475 ms 通过 | 61 ms 通过 |
| 4 | 5× | 2298 ms 通过 | 269 ms 通过 |
| 8 | 9× | 4119 ms 通过 —— 已用掉 82% 预算 | 470 ms 通过 |
| 10 | 11× | 5191 ms，Test timed out in 5000ms |
584 ms 通过 |
| 40 | 41× | （已经红了） | 2140 ms 通过 |
| 80 | 81× | （已经红了） | 4280 ms 通过 |
重复稳定性，每格连跑 8 次：9× 时 base 臂 0/8 红但已烧掉 87% 预算；11× 时 7/8 红。PR 臂两档都是 0/8 红，耗时 453–597 ms。base 在约 11× 超订处越过 5 秒预算；PR 臂外推到约 95×——大约多出 8.7 倍余量。完全不带 expect() 的裸扫描只需 14 ms：base 臂实测耗时中约 87% 来自那 65,536 次 expect() 调用，约 97% 与被测函数本身无关。
3. #10552 并没有覆盖这个场景
packages/acp-bridge/vitest.config.ts 只在 RUNNER_NAME 以 ecs-qwen- 开头时把上限提到 60 秒。把争用固定在 11×、只改 RUNNER_NAME：
| 臂 | RUNNER_NAME |
结果 | sweep |
|---|---|---|---|
| base | GitHub Actions 7 |
❌ 5000 ms 超时 | 5405 ms |
| base | ecs-qwen-linux-04 |
✅ 通过（60 秒上限） | 5440 ms |
| pr | GitHub Actions 7 |
✅ 通过 | 558 ms |
| pr | ecs-qwen-linux-04 |
✅ 通过 | 587 ms |
从 API 取到的真实 runner 名：ecs-qwen-hk1-*/ecs-qwen-hk3-*（Linux ECS）和 ecs-qwen-runner-win-hk-*（Windows ECS）都匹配该前缀；托管 runner 名为 GitHub Actions <id>，不匹配。因此仍停留在 5 秒默认值的 lane 是 ubuntu-latest 回退（fork PR，或 ECS kill-switch 打开时）与 macos-latest（merge_group / schedule / dispatch），两者都在仓库根跑 npm run test:ci。除了在那里消除抖动，这个改动还让每次套件运行在所有地方省下约 410 ms CPU。
4. 检测力没有损失——这是最该较真的部分
各臂对 packages/acp-bridge/src/json-string-bytes.ts 的 V8 覆盖率：
- 语句/分支/函数命中映射完全相同：
true - 命中次数不同的语句数：0
- 语句命中总数：base 2,108,931，PR 2,108,931
不是"百分比相同"，而是逐语句执行次数相同。循环仍然对全部 65,536 个码元求值两边；被提出去的只有断言调用。
逐个变异产品文件并在两臂上运行：
| 变异 | 不匹配码元数 | base | PR |
|---|---|---|---|
孤立代理项 6 → 3 字节 |
1024 | ❌ | ❌ 已杀死 |
从短转义集合中去掉 0x08 |
1 | ❌ | ❌ 已杀死 |
快路径 return b → return b + 1 |
63454 | ❌ | ❌ 已杀死 |
code <= 0x7f → 0x7e |
0 | ✅ | ✅ 等价变异 |
3/3 非等价变异体在两臂上都被杀死。最后一条是等价变异，因为 0x7f 根本到不了慢路径——对单码元输入而言，只有 2082/65536（3.2%） 能越过免转义快路径的正则。这是该测试原本就有的性质，两臂一致，与本 PR 无关；我提出来只是提醒别把"穷举"二字读过头。
批量形式在失败时信息还更多：它会报出出问题的 code，而逐次断言的旧写法只会打印 expected 5 to be 8。
5. 非阻塞，但值得顺手做：收集器没有上界
expect(mismatches).toEqual([]) 会把每一条不匹配都序列化进 CI 日志。在同样三个变异上实测：
| 变异 | base 输出 | PR 输出 |
|---|---|---|
| 1 条不匹配 | 3.2 kB / 78 行 | 3.2 kB / 84 行 |
| 1024 条 | 3.2 kB / 78 行 | 123 kB / 5199 行 |
| 63454 条 | 3.2 kB / 78 行 | 7.4 MB / 317,349 行 |
快路径被改坏正是这个测试存在的意义所在，而它恰好就是产生 7.4 MB 转储的那种情况。评审 bot 一直把这条挂在延后项里；这里给出它背后的数字。给报告加上界即可保留上面所有好处（代码见上方英文部分）。
我用该变体跑了那个 63,454 条不匹配的变异：失败输出为 4.0 kB / 108 行，仍然给出准确条数和最先出问题的几个码点。放在本 PR 里还是作为跟进由你决定——它不阻塞合入。
6. 现在的阻塞项是描述，不是代码
- PR 描述讲的修复已经不在 diff 里了。 "Raises the per-test timeout … to an explicit 60s"；Test Plan 第 3 步要求评审者"确认 diff 恰好只有一个超时参数加一条简短注释"；Risk 一节讨论 60 秒的报告延迟。在当前 head 上这些都不成立。三个 triage 阶段审的也都是被替换掉的方案——stage 2 还明确论证过批量化"改变了测试的失败形态，比问题本身要求的改动更大"，而现在交付的正是这个方案。
Fixes #10529仍然是错的，而且这次我是从该次 run 自己的 step 数据确认的，而非推断：在 run 33274358974（jobTest (ubuntu-latest, Node 22.x)，跑在ecs-qwen-runner-64c-7上），step 33Run .github/scripts helper tests失败，step 35Run tests and generate reports——唯一执行npm run test:ci的步骤——被跳过。acp-bridge 套件根本没有运行。issue Main CI failed: Qwen Code CI on 02f2101f4305 #10529 已于 2026-08-31 关闭，原因正是那个无关的 helper 测试失败。带着这个关联合入，等于用错误的根因重新关闭一个已关闭的 issue。
7. 红色检查与本 PR 无关
Test (ubuntu-latest, Node 22.x)（run 33622567465，跑在 ecs-qwen-hk4-13）：56871 通过，3 失败——packages/core 的 hook-runner.process.test.ts 与 recall-scan-latency.test.ts，以及 packages/web-shell 的 MessageList.dom.test.tsx。没有一条在 packages/acp-bridge，而那是本 PR 唯一触碰的包。两个 core 测试在 base 树本地全部通过（21/21），且 recall-scan-latency 在同一套争用 harness 下纯粹以负载抖动复现——expected 80.65542499999901 to be less than 50。与本 PR 同类的问题，不同的测试。
8. 回归检查
在每个臂里各自构建 packages/core 后跑完整 packages/acp-bridge 套件：base 与 PR 均为 34 个文件、1914 个测试全部通过。改动文件上的 eslint --max-warnings 0、prettier --check、tsc --noEmit 均干净。
建议
- 合入前（记账问题）： 把 "What this PR does"、"Reviewer Test Plan"、"Evidence"、"Risk & Scope" 四节围绕"只断言一次"重写，并去掉
Fixes #10529（保留为普通引用即可）。 - 然后合入。 该改动在托管 lane 上是承重件，在所执行的代码上可证等价，杀死同样的变异体，恢复了 ci: stabilize tests under shared ECS host contention #10552 的旋钮权威性，并且在所有地方都更快。
- 可选，现在或作为跟进： 按第 5 节给不匹配报告加上界。
🤖 Generated with Claude Code — Claude Opus 5 (1M context)
Asserting on the whole mismatch array serialised every divergence into the CI log. A broken no-escape fast path — the regression class this sweep exists to catch — diverges on 63,454 of the 65,536 code units and dumped 7.4 MB across 317k lines. Report the count and the first five entries instead: the same failure still names the exact count and the offending code points, in 4 kB.

This round made one code change — the maintainer's §5 recommendation — and leaves the single standing Critical escalated, because that Critical is PR metadata this bot cannot write. New head: 1. Critical R12-1 —

{ count, first: slice(0, 5) } (after) |
4,229 bytes / 113 lines | 5 |
That is a 1,753× reduction and independently corroborates the maintainer's 7.4 MB / 317,349-line and 4.0 kB / 108-line measurements. It also settles the question round 14 disclosed as unexplored — vitest does not truncate a toEqual diff at this size; it prints all 63,454 entries.
Mutation-probed the new assertion in both directions, since bounding a collector is exactly the kind of change that can silently lose detection:
| mutation | mismatches | result | reported detail |
|---|---|---|---|
fast path return unescapedBytes → + 1 |
63,454 | ❌ killed | expected { count: 63454, …(1) } to deeply equal { count: +0, first: [] } |
drop 0x08 from the short-escape set |
1 | ❌ killed | "first": [ { "code": 8, "got": 8, "want": 4 } ] |
The single-mismatch probe is the load-bearing one: the bounded form still catches one divergent code unit and still names it, so detection is not traded away for log volume. The production file was restored byte-identical after each probe (git diff --exit-code clean).
The shipped assertion is the maintainer's prescribed snippet verbatim in semantics; Prettier reflows it across more lines at this indent level than his report showed (npx prettier --check is clean).
3. Other points from ic:5509928882 — no action needed
- §1–§4, §8 (adopted diff, flake removal, ci: stabilize tests under shared ECS host contention #10552 coverage, detection equivalence, regression): corroborated locally — the changed file runs 5/5 green in ~50 ms, and the full package suite is 34 files / 1,914 tests green both before and after this round's change (same test count, nothing added or removed).
- §6 (body is the blocker): same item as §1 above; escalated.
- §7 (red check is unrelated): verified first-hand rather than taken on trust — see Failed checks below.
- Recommendation 2 ("then merge"): not this bot's call.

It clears on the maintainer's metadata edit, not on a commit.
5. Deliberately not done
- No why-comment added for the collect-once / bounded-report pattern (
D14-2, also deferred in round 13). It sits in the review'sDeferred under the convergence postureaudit section, which is a record and not work; AGENTS.md defaults comments to none; and the maintainer's prescribed snippet carries none. Flagging it here so the choice is visible rather than silent. - No merge of
origin/main.--conflict falsewas supplied. Noteorigin/mainhas advanced past this branch's merge-base (29baecd7→76c32fd5); a two-dotgit diff origin/maintherefore shows unrelated main-only work inverted, and the PR's real net diff is the three-dot form: one file, +10/−3, all test. - No

中文说明
本轮小结
当前处于仅处理 Critical 的模式（已完成 5 个产生改动的轮次）。本轮只做了一处代码改动——即维护者第 5 节的建议——并把唯一未决的 Critical 继续上报，因为该 Critical 属于本机器人无法写入的 PR 元数据。
新 head：5dcf62992c —— test(acp-bridge): bound the byte-estimate sweep's mismatch report（1 个文件，+6/−1，纯测试改动）。
1. Critical R12-1 —— Fixes #10529 认证 → 上报维护者（处置不变）
该发现出现在三条仍未关闭的线程上（rc:3911144154 第 13 轮、rc:3912216955 第 14 轮、rc:3913169248 第 15 轮），以及三份评审正文中（rv:5086085778、rv:5087368084、rv:5088493634）。
该发现被接受，没有争议。 代码载体已在第 13 轮移除并保持移除状态——本轮通过直接读取文件在 HEAD 上核实：json-string-bytes.test.ts 中没有任何 per-test 超时字面量（扫描测试的 it 直接以断言结束，没有第三个参数），因此 packages/acp-bridge/vitest.config.ts 在所有 lane 上仍具权威性。本轮没有回退或重塑「只断言一次」的结构。
为什么没有在此修复： 剩余的两个载体是 PR 标题（(#10529)）与 PR 正文（"Linked Issues" 与 "关联 Issue" 两节中的 Fixes #10529，外加 "What this PR does"、Test Plan 第 3 步、Risk & Scope 仍在描述已被撤回的 60 秒超时上调）。两者都是 GitHub 元数据，而此路径没有写入它们的通道：它没有 GitHub 凭据；pr-title.txt / pr-body.md 只被 develop-issue 路径中的 gh pr create 消费（qwen-autofix.yml:1541-1544）——只用于创建，从不用于编辑；并且 gh pr edit 在 qwen-autofix.yml 与 autofix-push-and-report.sh 中出现的次数都是零（已用 grep 核实）。而为了新增这样一个通道去改 .github/，对本机器人来说同样越界。
请求维护者执行的动作——措辞已在评论 3910803244 中给出，本轮不变：
- 标题 →
test(acp-bridge): deflake the exhaustive UTF-16 byte-estimate sweep - 正文 → 把
Fixes #10529换成一条非关闭性的普通引用，说明 Main CI failed: Qwen Code CI on 02f2101f4305 #10529 已按过期关闭、其记录的失败是无关的.github/scripts心跳抖动；并把 "What this PR does"、Test Plan 第 3 步与 Risk & Scope 改写为围绕「先收集、只断言一次」的改动，而非已被撤回的 60 秒上调。 - 不要把关闭关键字改为指向 Deferred review findings from PR #10532 #10547（那是一个延后发现的清单，不属于本 PR 的范围）。
三条线程都被刻意保留为未关闭，以便这个合入前必办项持续可见。
2. 维护者报告 ic:5509928882 第 5 节 —— 不匹配收集器没有上界 → 已实现
这是本轮唯一可执行的代码项。@wenshao 将其标为非阻塞，并给出「现在做或作为跟进」两种选择；本轮选择现在做，理由是：评审 bot 已连续三轮把同一发现挂在延后项里（D14-1、D15-2），窗口开启时测试行预算尚未动用（0/400），且把它关掉是从评审清单里移除一个反复出现的条目，而不是再加一层防御。
在动手改任何东西之前，我先独立复现了该结论：临时把 json-string-bytes.ts 中免转义快路径改坏（return unescapedBytes → + 1），测量扫描测试的失败输出：
| 形式 | 失败输出 | 序列化条目数 |
|---|---|---|
expect(mismatches).toEqual([])（改动前） |
7,416,456 字节 / 317,354 行 | 63,454 |
{ count, first: slice(0, 5) }（改动后） |
4,229 字节 / 113 行 | 5 |
即缩小 1,753 倍，并独立印证了维护者测得的 7.4 MB / 317,349 行与 4.0 kB / 108 行。这同时回答了第 14 轮披露为「未能探索」的那个问题——vitest 在这个体量下不会截断 toEqual 的 diff，它把全部 63,454 条都打印了出来。
对新断言做了双向变异探针，因为给收集器加上界正是那种可能悄悄丢掉检测力的改动：
| 变异 | 不匹配数 | 结果 | 报告细节 |
|---|---|---|---|
快路径 return unescapedBytes → + 1 |
63,454 | ❌ 已杀死 | expected { count: 63454, …(1) } to deeply equal { count: +0, first: [] } |
从短转义集合中去掉 0x08 |
1 | ❌ 已杀死 | "first": [ { "code": 8, "got": 8, "want": 4 } ] |
其中单条不匹配的探针是承重的那一个：加上界之后仍能捕获一个不一致的码元并仍能指出它是谁，因此没有用检测力去换日志体量。每次探针之后产品文件都恢复为逐字节相同（git diff --exit-code 干净）。
提交的断言在语义上与维护者给出的片段逐字一致；Prettier 在这一缩进层级上把它排成了比他报告里更多的行数（npx prettier --check 干净）。
3. ic:5509928882 的其余各点 —— 无需动作
- 第 1–4 节与第 8 节（采纳的 diff、抖动消除、ci: stabilize tests under shared ECS host contention #10552 是否已覆盖、检测力等价、回归检查）： 已在本地印证——改动文件 5/5 通过、约 50 ms；完整套件在本轮改动前后均为 34 个文件 / 1,914 个测试通过（测试数相同，没有增删）。
- 第 6 节（阻塞项是描述）： 与上面第 1 点是同一件事；已上报。
- 第 7 节（红色检查与本 PR 无关）： 我没有采信而是自己核实——见下方「失败的检查」。
- 建议 2（「然后合入」）： 不由本机器人决定。
4. 失败的检查
Test (ubuntu-latest, Node 22.x)—— FAILURE： 与本 PR 无关。我在这棵树上亲自跑了被点名的三个测试来确认：packages/core/src/hooks/hook-runner.process.test.ts20/20 通过、packages/core/src/memory/recall-scan-latency.test.ts1/1 通过（569 ms，在预算内）、packages/web-shell/client/components/MessageList.dom.test.tsx163/163 通过。三者都不在packages/acp-bridge（本 PR 唯一触碰的包），而那里的纯测试改动也不可能影响它们。与维护者的负载抖动判断一致。未做代码处理——去修一个packages/core里对时序敏感的测试，属于为一个本 PR 并不拥有的缺陷做足迹扩张。review-pr—— FAILURE： 这是评审 bot 自己的CHANGES_REQUESTED结论，即上面第 1 点的 Critical。它由维护者的元数据修改解除，而不是由某个提交解除。
5. 刻意没有做的事
- 没有为「只断言一次 / 报告加上界」添加解释性注释（
D14-2，第 13 轮也已延后）。它位于评审的Deferred under the convergence posture审计区，那是记录而不是工作；AGENTS.md 规定注释默认不写；维护者给出的片段本身也没有注释。在此说明是为了让这个选择可见，而不是无声无息。 - 没有合并
origin/main。 本次传入的是--conflict false。注意origin/main已经前进到本分支 merge-base 之后（29baecd7→76c32fd5）；因此两点式git diff origin/main会把仅存在于 main 的无关改动反向显示出来，本 PR 真实的净 diff 是三点式：一个文件，+10/−3，全部是测试。 - 没有写
deferred-findings.json。 唯一经核实为真、且在足迹之外的发现（真正导致 Main CI failed: Qwen Code CI on 02f2101f4305 #10529 记录失败的.github/scripts/autofix-status-heartbeat.test.mjs抖动）已由处于 OPEN 状态的 issue Deferred review findings from PR #10532 #10547 承载，条目为rc:3888574016（见第 15 轮证据），且由维护者负责。再提交一次会与既有清单条目重复，而我本人并未第一手核实过它，因此不该由我来延后。 - 省略
resolved-comments.txt—— 本轮没有任何来自行内评论的发现是在代码中被解决的。 - 运维说明：本检出没有配置 git 身份，因此设置了一份仓库级（非全局）的
user.name/user.email为qwen-code-dev-bot <qwen-code-dev@service.alibaba.com>（与分支上已有提交一致），以便完成提交。

未运行的命令及原因：npm run generate:settings-schema（没有改动 settings 源——diff 只有一个测试文件）；npm run bundle 加集成测试（被触碰的行为是 packages/acp-bridge 中的一个单元测试，由 Vitest 直接执行，并非只能通过打包后的 CLI 或集成 harness 才能触达）。

Partially reviewed — gaps disclosed.
Not explored to full depth (tool budget reached): "agent 3a": none — no check was cut short..
Not reviewed: reverse audit — stopped before round 1 by the review time budget.
Not reviewed: verification — the review posts findings, but no verifier was launched with a prompt this skill builds — they were ruled on, if at all, without the verdict bar its brief carries.
— [unverified] tag when the loop ended — the verifier never ruled on them, and they are not confirmed.
Test Plan (not a blocker): 5 tests passing — this review observed 1914, 298, 1768, 504, 5682, 94 passed.
Residual risk: this loop is persistently critical — Criticals stood in the previous round's work-list and stand again this round (1 Critical(s)), the rate of first-time findings is not falling (this round 0, previous 0), and the standing Critical backlog is not shrinking. The severity floor will not converge it. Recommendation: land-with-residual-risk — the exit is a maintainer risk-acceptance decision (merge, carrying the residual risk), not another review round. Residual-risk inventory for that decision (maintainer to complete):
| standing Critical | attack surface | attacker-dependency | blast radius |
|---|---|---|---|
| (each standing Critical) | … | … | … |
Advisory only — it does not block this review.
中文说明
仅完成部分审查，审查缺口已披露。
未探索到全部深度（达到工具调用预算）："agent 3a"：none — no check was cut short.。
未审查：反向审计——评审时间预算不足，未能开始第 1 轮。
未审查：验证——本次评审发布了发现，但没有验证 agent 是用本 skill 构建的 prompt 启动的——这些发现即便被裁定过，也缺失了 brief 承载的裁定标准。
— [unverified] 标记——验证者从未对它们作出裁决，它们不算已确认。
Test Plan（非阻断）：5 tests passing — this review observed 1914, 298, 1768, 504, 5682, 94 passed。
残余风险：本循环处于 persistently-critical 形态——上一轮工作清单中的 Critical 本轮依然存在（本轮 1 条 Critical），首次发现的速率没有下降（本轮 0，上一轮 0），且未决 Critical 积压没有减少。severity floor 无法使其收敛。建议：land-with-residual-risk——出口是 maintainer 的风险接受决定（合入并承担残余风险），而非再开一轮评审。供该决定使用的残余风险清单（maintainer 填写）：按每条未决 Critical 列出「攻击面 · 攻击者依赖性 · 影响范围」三栏。仅为建议——不阻断本次评审。

[Critical] R12-1: [certifies-falsely] [new-surface] This PR still certifies Fixes #10529 (body sections "Linked Issues" and "关联 Issue", title fix(acp-bridge): deflake the exhaustive UTF-16 byte-estimate test (#10529), branch autofix/issue-10529), but the failure issue #10529 records happened in a suite this PR never touches — the autofix-status-heartbeat loop subtest in .github/scripts/autofix-status-heartbeat.test.mjs — and the acp-bridge vitest step was skipped in run 33274358974, so the changed test never ran there. Replaying the issue's incident against this tree changes no step outcome: the heartbeat suite is byte-identical to the incident commit (git log 02f2101f4305..HEAD -- .github/scripts/autofix-status-heartbeat.test.mjs is empty at this HEAD), its stamps each tick in flight around the gh call and clears it after subtest still flakes under contention, the Run .github/scripts helper tests step exits 1, and Run tests and generate reports — the only step that executes this test — is skipped, the exact recorded shape. Issue #10529 is already CLOSED (2026-08-31) as stale with that heartbeat flake named as its cause, so merging puts a permanent false attribution on the record: the merge commit credits this acp-bridge test change with closing an issue whose recorded failure was an unrelated helper-suite flake, and anyone later bisecting a repeat heartbeat failure finds its tracking issue closed against a fix that never addressed it. This round's code change — bounding the sweep's mismatch report to the first five entries — is sound and does not alter the claim; the remaining carriers are the PR title and body, which the author bot cannot edit and has escalated to a maintainer (comment 3910803244).
Witness:
gh issue view 10529: state CLOSED, closedAt 2026-08-31T12:27:02Z
closing comment: "This failure was a flake in the .github/scripts helper tests
(autofix-status-heartbeat loop subtest) on an older commit. ... Closing as stale."
gh pr view 10532 (this round): title carries `(#10529)`; body carries
`Fixes #10529` in both "Linked Issues" sections; headRefName autofix/issue-10529
git log 02f2101f4305..HEAD -- .github/scripts/autofix-status-heartbeat.test.mjs -> empty
run 33274358974 step outcomes: "Run .github/scripts helper tests" failed;
"Run tests and generate reports" skipped (the only step running this suite)
Suggested fix: before merge, replace Fixes #10529 in both body sections with a plain non-closing reference recording that issue #10529 was closed as stale and its recorded failure was the unrelated .github/scripts heartbeat flake, and drop (#10529) from the title — e.g. test(acp-bridge): deflake the exhaustive UTF-16 byte-estimate sweep. No code change is needed; do not re-point the closing keyword at #10547. Fix constraint: maintainer @wenshao's round-2 verification report (comment 5509928882), Recommendation 1 — "drop Fixes #10529 (a plain reference is fine)"; the metadata fix must not touch the code diff, which the same report certifies for merge.
中文说明
R12-1：本 PR 仍然声明 Fixes #10529（正文 "Linked Issues" 与 "关联 Issue" 两节、标题 fix(acp-bridge): deflake the exhaustive UTF-16 byte-estimate test (#10529)、分支 autofix/issue-10529），但 issue #10529 记录的失败发生在本 PR 从未触碰的套件中——.github/scripts/autofix-status-heartbeat.test.mjs 的 autofix-status-heartbeat loop 子测试——且在 run 33274358974 中，acp-bridge 的 vitest 步骤被跳过，被改动的测试根本没有运行。把该 issue 记录的事故在这棵树上重放，没有任何步骤的结果会改变：心跳套件与事故提交逐字节相同（git log 02f2101f4305..HEAD -- .github/scripts/autofix-status-heartbeat.test.mjs 为空），其 stamps each tick in flight around the gh call and clears it after 子测试在争用下仍会抖动，Run .github/scripts helper tests 步骤以 1 退出，唯一会执行本测试的 Run tests and generate reports 被跳过——与记录中的形态完全一致。issue #10529 已于 2026-08-31 按"过期"关闭，并明确记录原因为该心跳抖动，因此合并会在记录上留下永久的错误归因：合并提交会把一个 acp-bridge 测试改动记为关闭了某个失败与其无关的 issue，日后有人对再次出现的心跳失败做二分定位时，会发现其追踪 issue 已被一个从未处理过它的修复关闭。本轮的代码改动——把扫描的不匹配报告上界设为前 5 条——本身正确，不改变上述结论；剩余的载体是 PR 标题与正文，作者机器人无权编辑，已就此上报维护者（评论 3910803244）。
证据（上方 Witness 代码块，命令输出为固定格式未翻译）：issue #10529 已关闭且关闭评论指明原因为心跳抖动；本轮 PR 元数据仍含 Fixes #10529；心跳测试文件自事故提交以来无任何提交触碰；该次运行中唯一失败的步骤是 helper tests，vitest 步骤被跳过。
建议修复：合入前把正文两节的 Fixes #10529 替换为普通的非关闭性引用（说明 issue #10529 已按过期关闭、其记录的失败是无关的 .github/scripts 心跳抖动），并从标题移除 (#10529)，例如改为 test(acp-bridge): deflake the exhaustive UTF-16 byte-estimate sweep。无需改动代码；也不要把关闭关键字改为指向 #10547。修复约束：维护者 @wenshao 第 2 轮验证报告（评论 5509928882）建议 1——"去掉 Fixes #10529（保留为普通引用即可）"；元数据修复不得触碰代码 diff，同一报告已认证代码改动可以合入。

Disposition: escalated to a maintainer — not resolved in code, so this thread stays open.
Re-verified at head 5dcf62992c rather than carried over:
- The code carrier is gone. The entire PR diff is
packages/acp-bridge/src/json-string-bytes.test.ts(+10/−3, test-only); read at HEAD it carries no per-test timeout literal, sopackages/acp-bridge/vitest.config.tsstays authoritative on every lane, and the changed test runs 5/5 green in 55 ms. - The remaining carriers are the PR title and body, and this path has no channel for them:
pr-title.txt/pr-body.mdare consumed only bygh pr createin the develop-issue publish step (qwen-autofix.yml:1541-1544),gh pr editandupdatePullRequestappear zero times in that workflow, the address path consumes onlyaddress-summary.md/no-action.md/failure.md/handoff.md/resolved-comments.txt/comment-replies.json/deferred-findings.json/growth-audit.json(qwen-autofix.yml:5521-5592), and this agent holds no GitHub credentials. Adding an edit channel would mean editing.github/, which is out of bounds for this loop.
New evidence this round, which supports the finding rather than weakening it. Since this branch's merge-base (29baecd780), the only CI-lane commit on main is 3483836895 fix(ci): stop heartbeat mint-skip test racing loop startup (#10527). It rewrites a subtest of .github/scripts/autofix-status-heartbeat.test.mjs — the suite issue #10529's closing comment names — because the pre-fix fixed 2.5 s sleep let "bash startup plus the tick's forks land after that budget on a loaded runner — reddening the helper-tests lane with no product defect". Main therefore records in writing that this suite reddens the Test lane with no product defect: the same attribution this finding makes, and the opposite of what Fixes #10529 claims.
One observation for whoever owns #10547, stated as a code-shape fact and not as a verified defect: the subtest this finding names (stamps each tick in flight around the gh call and clears it after, line 866 at HEAD) is not touched by #10527 — the file's diff has two hunks, @@ -833,6 and @@ -848,21, both in the mint-skip region — and on main it still gates two full loop ticks behind a fixed waitFor(..., 8000), the shape #10527 calls a race. I did not reproduce a failure of it: invoked exactly as CI invokes it, the suite passed 29/29 twice at HEAD, at loadavg 11.1 and at loadavg 66.7 on 64 cores (the subtest took 3051 ms and 3209 ms).
The ask is unchanged (comment 3910803244, reconfirmed by @wenshao in 5509928882 Recommendation 1): title → test(acp-bridge): deflake the exhaustive UTF-16 byte-estimate sweep; body → replace Fixes #10529 in both the "Linked Issues" and "关联 Issue" sections with a plain non-closing reference recording that #10529 was closed as stale and that its recorded failure was the unrelated .github/scripts heartbeat flake, and bring "What this PR does" / Test Plan step 3 / Risk & Scope in line with the collect-then-assert-once change (the 60 s raise was withdrawn in 3f56e9a8c7); do not re-point the closing keyword at #10547.
On the red Test (ubuntu-latest, Node 22.x) check named in this round's feedback: it cannot come from this diff, the branch is 20+ commits behind main and still carries the pre-#10527 helper suite, --conflict false was supplied so this round merges nothing, and the logs of run 33637618240 are unavailable to an agent with no credentials — so the failing step cannot be named with certainty. A red lane that passes on current main is the workflow's base-update mechanism's job, which has already fired five times on this PR.
中文说明
处置：上报维护者 —— 未在代码中解决，因此该线程保持开放。
以下均在 head 5dcf62992c 上重新核实，不是沿用旧结论：
- 代码载体已移除。本 PR 的完整 diff 只有
packages/acp-bridge/src/json-string-bytes.test.ts（+10/−3，纯测试）；在 HEAD 上读取，它不含任何 per-test 超时字面量，因此packages/acp-bridge/vitest.config.ts在所有 lane 上仍具权威性，被改动的测试 5/5 通过、耗时 55 ms。 - 剩余载体是 PR 标题与正文，而此路径没有写入它们的通道：
pr-title.txt/pr-body.md只被 develop-issue 发布步骤中的gh pr create消费（qwen-autofix.yml:1541-1544）；gh pr edit与updatePullRequest在该 workflow 中出现次数为零；address 路径只消费address-summary.md/no-action.md/failure.md/handoff.md/resolved-comments.txt/comment-replies.json/deferred-findings.json/growth-audit.json（qwen-autofix.yml:5521-5592）；并且本 agent 没有 GitHub 凭据。新增一个编辑通道意味着修改.github/，这越过本循环的边界。
本轮的新证据，它支持而非削弱该发现。 自本分支 merge-base（29baecd780）以来，main 上唯一的 CI 相关提交是 3483836895 fix(ci): stop heartbeat mint-skip test racing loop startup (#10527)。它改写了 .github/scripts/autofix-status-heartbeat.test.mjs（即 issue #10529 关闭评论点名的套件）中的一个子测试，原因是修复前那个固定的 2.5 秒 sleep 会让「bash 启动加上该 tick 的多次 fork 在负载较高的 runner 上超出预算 —— 让 helper-tests lane 变红，而没有任何产品缺陷」。因此 main 已以文字形式记录：这个套件会在没有产品缺陷的情况下让 Test lane 变红 —— 与该发现的归因一致，也与 Fixes #10529 的声称相反。
一条给 #10547 负责人的观察，作为代码形态事实陈述，而非已核实的缺陷：该发现点名的子测试（stamps each tick in flight around the gh call and clears it after，HEAD 上第 866 行）并没有被 #10527 触碰 —— 该文件的 diff 只有两个 hunk，@@ -833,6 与 @@ -848,21，都在 mint-skip 区域 —— 且在 main 上它仍把两个完整的 loop tick 关在固定的 waitFor(..., 8000) 之后，正是 #10527 称之为竞态的形态。我没有复现出它的失败：以与 CI 完全一致的方式调用，该套件在 HEAD 上两次都是 29/29 通过，分别在 loadavg 11.1 与 64 核 loadavg 66.7 下（该子测试耗时 3051 ms 与 3209 ms）。
请求事项不变（评论 3910803244，并由 @wenshao 在 5509928882 建议 1 中再次确认）：标题 → test(acp-bridge): deflake the exhaustive UTF-16 byte-estimate sweep；正文 → 把 "Linked Issues" 与 "关联 Issue" 两节中的 Fixes #10529 换成一条非关闭性的普通引用，说明 #10529 已按过期关闭、其记录的失败是无关的 .github/scripts 心跳抖动，并把 "What this PR does" / Test Plan 第 3 步 / Risk & Scope 改写为与「先收集、只断言一次」的改动一致（60 秒上调已在 3f56e9a8c7 中撤回）；不要把关闭关键字改为指向 #10547。
关于本轮反馈中点名的红色检查 Test (ubuntu-latest, Node 22.x)：它不可能来自本 diff；本分支落后 main 20 多个提交，仍携带 #10527 之前的 helper 套件；本次传入 --conflict false，因此本轮不做任何合并；而没有凭据的 agent 拿不到 run 33637618240 的日志，所以无法确定失败的具体步骤。「在当前 main 上能通过」的红色 lane 属于 workflow base 更新机制的职责，该机制在本 PR 上已触发过五次。

- Stale PR body/Test Plan describing the superseded timeout raise — already reported (round-15 deferral D15-1, review 5088493634)
Not reviewed: reverse audit — stopped before round 1 by the review time budget.
Test Plan (not a blocker): 5 tests passing — this review observed 1919, 298, 1769, 504, 5718, 94 passed.
Residual risk: this loop is persistently critical — Criticals stood in the previous round's work-list and stand again this round (1 Critical(s)), the rate of first-time findings is not falling (this round 0, previous 0), and the standing Critical backlog is not shrinking. The severity floor will not converge it. Recommendation: land-with-residual-risk — the exit is a maintainer risk-acceptance decision (merge, carrying the residual risk), not another review round. Residual-risk inventory for that decision (maintainer to complete):
| standing Critical | attack surface | attacker-dependency | blast radius |
|---|---|---|---|
| (each standing Critical) | … | … | … |
Advisory only — it does not block this review.

[Critical] R12-1: [certifies-falsely] [new-surface] This PR still certifies Fixes #10529 (body sections "Linked Issues" and "关联 Issue", title (#10529), branch autofix/issue-10529), but the failure issue #10529 records happened in a suite this PR never touches — the autofix-status-heartbeat loop subtest in .github/scripts/autofix-status-heartbeat.test.mjs — and the acp-bridge vitest suite never even ran in the referenced CI run. Round 17: still stands — independently re-verified this round against the incident job's raw log and live GitHub state.
The incident job's own log settles the attribution: the Run .github/scripts helper tests step failed on the heartbeat subtest, the job ended there, and the vitest step that executes this PR's test was skipped — the run failed before any test result was reported, which is exactly the shape issue #10529 records. Merging carries Fixes #10529 into history and attributes that failure's remedy to a PR that touches only packages/acp-bridge, so any recurrence bisects to the wrong change. The issue is already closed as stale (the maintainer attributed the failure to the heartbeat flake, and the heartbeat race was later fixed on main by #10527), so the harm is a false certification on the record, not auto-closure of an open issue. The deflake itself is sound and maintainer-verified; the defect is exclusively the certification.
Witness:
job 99165081177 raw log (run 33274358974):
not ok 18 - stamps each tick in flight around the gh call and clears it after
error: 'expected at least two PATCH calls with stamp observations'
not ok 17 - autofix-status-heartbeat loop
# tests 489 / # pass 488 / # fail 1
(zero vitest execution lines in the entire log)
gh pr view 10532 (live): title `fix(acp-bridge): deflake the exhaustive UTF-16
byte-estimate test (#10529)`; body `## Linked Issues` and `## 关联 Issue`
both carry `Fixes #10529`
gh issue view 10529 (live): CLOSED 2026-08-31 — "flake in the `.github/scripts`
helper tests (`autofix-status-heartbeat loop` subtest) ... Closing as stale"
git diff origin/main...HEAD --stat: only
packages/acp-bridge/src/json-string-bytes.test.ts (+10/-3); .github/ diff empty
Either drop the Fixes #10529 linkage and the (#10529) title reference (a plain reference is fine) and ship this as a standalone deflake whose evidence is the local reproduction of the sweep-test timeout, or retarget the autofix at the heartbeat suite. The author bot has stated PR title/body/branch are metadata writes it cannot perform; this is the maintainer decision the thread has been escalated for since round 1.
中文说明
R12-1（Critical，certifies-falsely / new-surface）：本 PR 仍然认证 Fixes #10529（正文 "Linked Issues" 与 "关联 Issue" 两节、标题 (#10529)、分支 autofix/issue-10529），但 issue #10529 记录的失败发生在本 PR 从未触碰的套件——.github/scripts/autofix-status-heartbeat.test.mjs 的 autofix-status-heartbeat loop 子测试——而且被引用的 CI 运行中 acp-bridge 的 vitest 套件根本没有执行。第 17 轮：仍然成立——本轮已对照事故任务的原始日志与 GitHub 实时状态独立复核。
事故任务自己的日志确定了归因：Run .github/scripts helper tests 步骤失败于该心跳子测试，任务随即终止，执行本 PR 测试的 vitest 步骤被跳过——运行在任何测试结果上报之前失败，这正是 issue #10529 所记录的形态。按当前提交合入会把 Fixes #10529 带入历史，把该失败的修复归因于一个只触碰 packages/acp-bridge 的 PR，今后任何复发都会 bisect 到错误的变更。该 issue 已作为过期关闭（维护者将失败归因于该心跳抖动，且该竞争问题后来已由 main 上的 #10527 修复），因此危害是记录上的错误认证，而非自动关闭一个未关闭的 issue。消抖本身正确且已经维护者验证；缺陷仅在于这一认证。
修复方式二选一：移除 Fixes #10529 关联与 (#10529) 标题引用（保留为普通引用即可），将本改动作为独立消抖提交，其证据即对扫描测试超时的本地复现；或者将 autofix 重新对准该心跳套件。作者 bot 已声明 PR 标题/正文/分支是它无法写入的元数据；这是自第 1 轮起升级给维护者的决定。

Escalated — not implementable in-tree. This thread stays open.
Confirmed and not disputed. In run 33274358974 the Run .github/scripts helper tests step failed on the autofix-status-heartbeat loop subtest and Run tests and generate reports — the only step that executes npm run test:ci, and therefore the only one that ever runs the acp-bridge suite — was skipped. So Fixes #10529 is a false certification on the record. Maintainer @wenshao reached the same conclusion independently from the run's own step data (§1 and §6 of their two verification reports).
Neither remediation this finding offers is available to this loop:
- Dropping the
Fixes #10529linkage and the(#10529)title reference is a PR title / body / branch write. This loop has no GitHub credentials and performs no network writes — the workflow owns them. That is the same boundary this thread has been escalated against since round 1. - Retargeting at the heartbeat suite means editing
.github/scripts/autofix-status-heartbeat.test.mjs..github/is CI machinery this PR was never about, which this loop may not modify, and it is outside the PR's footprint, which the gate rejects. It is also moot: the heartbeat race was already fixed on main by3483836895 fix(ci): stop heartbeat mint-skip test racing loop startup (#10527)— verified an ancestor of this head — and Main CI failed: Qwen Code CI on 02f2101f4305 #10529 has been closed since 2026-08-31.
The maintainer's instruction is already on the record and is bookkeeping, not code: "merge the code change, but drop or downgrade the Fixes #10529 link first", and in round 2 "rewrite 'What this PR does', 'Reviewer Test Plan', 'Evidence' and 'Risk & Scope' around the assert-once change, and drop Fixes #10529 (a plain reference is fine)". What remains is executing that metadata write.
Question for the maintainer: will you — or the workflow — apply those metadata edits (demote Fixes #10529 and the title reference to plain references, rewrite the body around the assert-once change) so this can merge? Re-running this loop will keep returning the same report: there is no edit inside this PR's one-file footprint that closes this finding.
Code state for the merge decision, re-verified this round at head 488a1d9a29 (a base-update merge carrying no source or test edits): unchanged and green. packages/acp-bridge 34 files / 1919 tests passed in 20.6 s; the changed file 5 tests in 49 ms; eslint --max-warnings 0 and prettier clean; grep -c '60_000' on the changed file is 0, so #10552's ECS-conditional testTimeout knob is authoritative for this test again. The diff is the assert-once rewrite plus the bounded mismatch collector from @wenshao's round-2 §5. Full detail in this round's report.

升级 —— 无法在代码树内实施。本线程保持开放。
已确认，不作反驳。在 run 33274358974 中，Run .github/scripts helper tests 步骤失败于 autofix-status-heartbeat loop 子测试，而 Run tests and generate reports —— 唯一执行 npm run test:ci、也就是唯一会运行 acp-bridge 套件的步骤 —— 被跳过。因此 Fixes #10529 是记录上的一次错误认证。维护者 @wenshao 对照该 run 自己的步骤数据独立得出同样结论（见其两份验证报告的 §1 与 §6）。
该发现给出的两种修复方式，本循环都无权执行：
- 移除
Fixes #10529关联与(#10529)标题引用 属于 PR 标题 / 正文 / 分支的写入。本循环没有 GitHub 凭据，也不执行任何网络写入 —— 这些由 workflow 负责。这与该线程自第 1 轮起持续升级所依据的边界是同一个。 - 重新对准心跳套件 意味着编辑
.github/scripts/autofix-status-heartbeat.test.mjs。.github/属于本 PR 从未涉及的 CI 机制，本循环不得修改；它也超出本 PR 的 footprint，会被门禁拒绝。而且已无意义：该心跳竞争问题已由 main 上的3483836895 fix(ci): stop heartbeat mint-skip test racing loop startup (#10527)修复（已验证为本 head 的祖先），且 Main CI failed: Qwen Code CI on 02f2101f4305 #10529 自 2026-08-31 起已关闭。
维护者的指令已在记录上，且属记账而非代码："合入代码改动，但先去掉或降级 Fixes #10529 关联"；第 2 轮补充 "把 'What this PR does'、'Reviewer Test Plan'、'Evidence' 与 'Risk & Scope' 围绕只断言一次的改动重写，并去掉 Fixes #10529（保留为普通引用即可）"。剩下的就是执行这次元数据写入。
给维护者的问题： 是否由您（或 workflow）来应用这些元数据修改（把 Fixes #10529 与标题引用降级为普通引用，并围绕只断言一次的改动重写正文），以便本 PR 可以合入？重跑本循环只会持续返回同样的报告：在本 PR 单文件的 footprint 之内，不存在能关闭该发现的编辑。
供合入决定使用的代码状态，本轮已在 head 488a1d9a29（一次不含源码或测试改动的 base 更新合并）重新验证：未改动且为绿。packages/acp-bridge 34 个文件 / 1919 个测试通过，耗时 20.6 秒；改动文件 5 个测试、49 毫秒；eslint --max-warnings 0 与 prettier 均干净；对改动文件执行 grep -c '60_000' 为 0，因此 #10552 的 ECS 条件 testTimeout 旋钮对该测试重新具有权威性。该 diff 就是只断言一次的重写，外加 @wenshao 第 2 轮 §5 的有界不匹配收集器。完整细节见本轮报告。

[Critical] R12-1: [certifies-falsely] [new-surface] This PR still certifies Fixes #10529 (body sections "Linked Issues" and "关联 Issue", PR title fix(acp-bridge): deflake the exhaustive UTF-16 byte-estimate test (#10529), branch autofix/issue-10529), but the failure issue #10529 records happened in a suite this PR never touches — the autofix-status-heartbeat loop subtest stamps each tick in flight around the gh call and clears it after in .github/scripts/autofix-status-heartbeat.test.mjs — and the vitest step that executes this PR's test was skipped entirely in run 33274358974. Round 18: still stands — re-verified at HEAD 4e8d80b6 this round: the diff still touches only this test file (git diff bedc404e98..HEAD -- .github/ is empty), the PR body still carries the closing keyword twice, and the maintainer's diagnosis of the recorded failure stands. The deflake itself is sound and maintainer-verified; the defect is exclusively the certification. Merging as-is makes the squash record certify that this change fixed run 33274358974's failure — a failure the maintainer diagnosed as a .github/scripts helper-test flake — and the "fixed by" cross-reference points the heartbeat flake at an unrelated test file. Issue #10529 was closed as stale, so no auto-close harm remains; the false certification in the merge record is the residual defect.
Witness:
gh run view 33274358974: step "Run .github/scripts helper tests" -> X (failure); step "Run tests and generate reports" -> - (skipped; this PR's test never ran)
gh issue view 10529: @yiliang114: "This failure was a flake in the .github/scripts helper tests (autofix-status-heartbeat loop subtest) on an older commit. … Closing as stale." (state CLOSED)
gh pr view 10532: body carries "Fixes #10529" under "Linked Issues" and again under "关联 Issue"
git diff bedc404e98..HEAD --stat -> packages/acp-bridge/src/json-string-bytes.test.ts (only file); git diff bedc404e98..HEAD -- .github/ -> empty
Fix: drop the closing keyword — replace Fixes #10529 with a non-closing reference in both body sections and remove (#10529) from the PR title; restate the change as a standalone deflake whose evidence is the local reproduction in the E2E report. This is a PR-metadata edit the author bot has stated it cannot perform from an additive commit — it needs a maintainer. Note the fix must remove the keyword from BOTH body sections: GitHub parses closing keywords anywhere in the body, and it appears twice ("Linked Issues" and "关联 Issue"); removing it from only one leaves the certification live (source: current PR body).
中文说明
本 PR 仍然认证 Fixes #10529（正文 "Linked Issues" 与 "关联 Issue" 两节、PR 标题 fix(acp-bridge): deflake the exhaustive UTF-16 byte-estimate test (#10529)、分支 autofix/issue-10529），但 issue #10529 记录的失败发生在本 PR 从未触碰的套件中——.github/scripts/autofix-status-heartbeat.test.mjs 中 autofix-status-heartbeat loop 套件的子测试 stamps each tick in flight around the gh call and clears it after——而且在 run 33274358974 中，执行本 PR 测试的 vitest 步骤被完全跳过。第 18 轮：仍然成立——本轮在 HEAD 4e8d80b6 复核：diff 仍然只触碰本测试文件（git diff bedc404e98..HEAD -- .github/ 为空），PR 正文仍在两处携带关闭关键字，maintainer 对该次失败的诊断也仍然有效。消抖本身是合理的且已经 maintainer 验证；缺陷仅在于这一认证。按当前提交合并会使 squash 记录认定本改动修复了 run 33274358974 的失败——而该失败被诊断为 .github/scripts 辅助测试的抖动——"fixed by" 交叉引用也会把心跳抖动指向一个无关的测试文件。Issue #10529 已被以 stale 关闭，因此不再有合并自动关闭的危害；残存的缺陷是合并记录中的错误认证。
证据：gh run view 33274358974：Run .github/scripts helper tests 步骤失败（X），Run tests and generate reports 步骤被跳过（-；本 PR 的测试从未执行）；gh issue view 10529：@yiliang114："This failure was a flake in the .github/scripts helper tests (autofix-status-heartbeat loop subtest) on an older commit. … Closing as stale."（状态：已关闭）；gh pr view 10532：正文在 "Linked Issues" 与 "关联 Issue" 下各有一处 "Fixes #10529"；git diff bedc404e98..HEAD --stat 仅 packages/acp-bridge/src/json-string-bytes.test.ts 一个文件；git diff bedc404e98..HEAD -- .github/ 为空。
修复方式：移除关闭关键字——将两处正文中的 Fixes #10529 改为非关闭引用，并从 PR 标题中移除 (#10529)；将本改动重新表述为独立消抖，其证据为 E2E 报告中的本地复现。这是 PR 元数据编辑，作者 bot 已声明无法通过追加提交完成——需要 maintainer 处理。注意修复必须同时移除两处正文中的关键字：GitHub 会解析正文任意位置的关闭关键字，而该关键字出现了两次（"Linked Issues" 与 "关联 Issue"）；只移除一处，认证仍然有效（来源：当前 PR 正文）。

Round 18: confirmed again at HEAD 75ea637edb; still not implementable from this loop, so the thread stays UNRESOLVED for a maintainer.
Re-verified locally this round rather than carried over:
git diff $(git merge-base origin/main HEAD)..HEAD --stat→ one file,packages/acp-bridge/src/json-string-bytes.test.ts, +10/−3;git diff fa5f7a11a0..HEAD -- .github/→ empty. The heartbeat suite issue Main CI failed: Qwen Code CI on 02f2101f4305 #10529 records is untouched, as the finding states.- No commit message on the branch carries a closing keyword (
a623924a's(#10529)is a parenthetical reference, and history rewriting is forbidden anyway), so the live closing reference is exclusively the PR body'sFixes #10529— in both "Linked Issues" and "关联 Issue", exactly as the finding says.
The finding is real and undisputed. What has not changed in 18 rounds is that its only fix is a GitHub metadata write this loop cannot make, re-verified this round from the workflow source and the environment rather than asserted:
grep -n "gh pr edit" .github/workflows/qwen-autofix.yml→ no matches. The address-review lane has no PR-title/body edit mechanism.pr-body.mdis consumed exactly once in the whole workflow —gh pr create --body-fileat line 1544, develop-issue lane only. It is never re-read after creation, so writing an updated body file this round would change nothing.gh auth status→ "You are not logged into any GitHub hosts." No credentials, and the loop's rules forbid using any.
Retargeting the fix at the heartbeat suite is also unavailable (.github/ is a protected area outside this PR's packages/acp-bridge footprint) and no longer wanted — @yiliang114 closed #10529 as a stale flake on 2026-08-31.
For the maintainer — two commands, then merge. @wenshao already reached this conclusion twice (ic:5503235459 §Recommendation 1, ic:5509928882 §6 and §Recommendation 1: "merge the code … but rewrite the PR body first"), and the code side is done: the assert-once rewrite plus the bounded { count, first } report from ic:5509928882 §5 are both at HEAD, green (npx vitest run src/json-string-bytes.test.ts → 5/5, 175ms file duration against vitest's 5s default).
gh pr edit 10532 --body …— replaceFixes #10529with a non-closing reference (e.g.Refs #10529) in both body sections. GitHub parses closing keywords anywhere in the body, so editing only one leaves the certification live. In the same edit, restate "What this PR does" / "Reviewer Test Plan" / "Evidence" / "Risk & Scope" around the change actually shipped instead of the superseded 60s timeout raise (that is the deferred D15-1 item — same edit, same command).gh pr edit 10532 --title 'test(acp-bridge): assert the exhaustive UTF-16 byte-estimate sweep once per run'— drop(#10529). The squash-merge commit title follows the PR title, so this is what keeps the closing reference out of the merge record.
The round-18 review's own exit recommendation is land-with-residual-risk — a maintainer risk-acceptance decision, not another review round. This bot has no further path to that edit and will keep reporting the same blocker until it lands.

第 18 轮：已在 HEAD 75ea637edb 上再次确认；本循环仍无法实施，因此线程保持未解决，交由维护者处理。
本轮在本地重新核实，而非沿用旧结论：
git diff $(git merge-base origin/main HEAD)..HEAD --stat→ 只有一个文件packages/acp-bridge/src/json-string-bytes.test.ts，+10/−3；git diff fa5f7a11a0..HEAD -- .github/→ 为空。issue Main CI failed: Qwen Code CI on 02f2101f4305 #10529 记录的心跳套件未被触碰，与该发现一致。- 分支上没有任何 commit message 携带关闭关键字（
a623924a的(#10529)是括号引用，且本就禁止重写历史），因此当前存活的关闭引用只存在于 PR 正文的Fixes #10529——位于 "Linked Issues" 与 "关联 Issue" 两处，正如该发现所述。
该发现属实且无争议。18 轮以来未曾改变的是：它唯一的修复是一次本循环无法执行的 GitHub 元数据写入——本轮已从 workflow 源码与运行环境重新核实，而非凭空断言：
grep -n "gh pr edit" .github/workflows/qwen-autofix.yml→ 无任何匹配。address-review 通道不存在修改 PR 标题/正文的机制。pr-body.md在整个 workflow 中只被消费一次——第 1544 行的gh pr create --body-file，且仅在 develop-issue 通道。PR 创建后它再也不会被读取，因此本轮即使写出更新后的正文文件也不会产生任何效果。gh auth status→ "You are not logged into any GitHub hosts"。无凭据，且本循环规则禁止使用凭据。
把修复重新对准入心跳套件同样不可行（.github/ 是受保护区域，且在本 PR 的 packages/acp-bridge 足迹之外），也已不再被期望——@yiliang114 已于 2026-08-31 将 #10529 作为过期抖动关闭。
给维护者——两条命令，然后合入。 @wenshao 已两次得出同一结论（ic:5503235459 建议 1；ic:5509928882 第 6 节与建议 1："合入代码……但请先重写 PR 正文"），而代码侧已经完成：ic:5509928882 第 5 节要求的只断言一次改写与受限的 { count, first } 报告都已在 HEAD 上，且为绿（npx vitest run src/json-string-bytes.test.ts → 5/5，文件耗时 175ms，相对 vitest 默认的 5 秒预算）。
gh pr edit 10532 --body …—— 将Fixes #10529替换为非关闭引用（例如Refs #10529），且两处正文都要改。GitHub 会解析正文任意位置的关闭关键字，因此只改一处，认证仍然有效。同一次编辑中，请把 "What this PR does" / "Reviewer Test Plan" / "Evidence" / "Risk & Scope" 按实际交付的改动重写，而不是已被取代的 60 秒超时上调（即延后项 D15-1——同一次编辑、同一条命令）。gh pr edit 10532 --title 'test(acp-bridge): assert the exhaustive UTF-16 byte-estimate sweep once per run'—— 移除(#10529)。squash 合并的提交标题跟随 PR 标题，因此这一步才能保证关闭引用不进入合并记录。
第 18 轮评审自身给出的出口建议是 land-with-residual-risk——维护者的风险接受决定，而非再开一轮评审。本机器人已无通往该编辑的进一步路径，在该编辑落地前只能持续报告同一个阻塞点。

Partially reviewed — gaps disclosed.
Not reviewed: reverse audit — stopped before round 1 by the review time budget.

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

[Critical] R12-1: [certifies-falsely] [new-surface] This PR still certifies Fixes #10529 — in both body sections ("Linked Issues" and "关联 Issue"), in the title (#10529), and through the branch name autofix/issue-10529 — but the failure issue #10529 records happened in a suite this PR never touches: the autofix-status-heartbeat loop subtest stamps each tick in flight around the gh call and clears it after in .github/scripts/autofix-status-heartbeat.test.mjs. In the referenced CI run 33274358974 the job died at the Run .github/scripts helper tests step, and the Run tests and generate reports step — the only step that executes this PR's test — was skipped, so this change cannot have fixed the recorded failure. Round 19: still stands — re-verified at HEAD 75ea637e this round against the run's own job log and the live PR metadata; issue #10529 was closed as stale on 2026-08-31, so the residual defect is the false certification in the merge record, plus a body that still describes the superseded 60s timeout raise instead of the assert-once change that ships. If merged as-is, the squash record certifies that this change fixed run 33274358974's failure against a wrong root cause, and when the same heartbeat subtest flakes again under load, main CI goes red with the tracking issue already closed and no open tracker left. The deflake itself is sound and maintainer-verified; the defect is exclusively the certification. Fix: replace Fixes #10529 with a non-closing reference in BOTH body sections, remove (#10529) from the title, and rewrite the stale body sections ("What this PR does", Test Plan step 3, Evidence, Risk) around the assert-once change — PR-metadata bookkeeping only, no code change. The keyword must come out of BOTH sections: GitHub parses closing keywords anywhere in the body, and removing it from only one leaves the certification live.

The remediation must not revert or reshape the code change — maintainer @wenshao round-2 verification report (PR comment 5509928882): "drop Fixes #10529 (a plain reference is fine). Then merge. The change is causally load-bearing on the hosted lanes, provably equivalent in what it exercises, kills the same mutants, restores the #10552 knob, and is faster everywhere."
中文说明
本 PR 仍然认证 Fixes #10529——正文两处（"Linked Issues" 与 "关联 Issue"）、标题 (#10529)、分支名 autofix/issue-10529——但 issue #10529 记录的失败发生在本 PR 从未触碰的套件中：.github/scripts/autofix-status-heartbeat.test.mjs 中 autofix-status-heartbeat loop 套件的子测试 stamps each tick in flight around the gh call and clears it after。在被引用的 CI run 33274358974 中，任务在 Run .github/scripts helper tests 步骤失败终止，而唯一执行本 PR 测试的 Run tests and generate reports 步骤被跳过，因此本改动不可能修复该次记录的失败。第 19 轮：仍然成立——本轮在 HEAD 75ea637e 对照该次运行的原始任务日志与 PR 实时元数据复核；issue #10529 已于 2026-08-31 以 stale 关闭，残存缺陷是合并记录中的错误认证，以及正文仍在描述已被替换的 60 秒超时上调、而非实际提交的 assert-once 改动。按当前状态合并，squash 记录会认定本改动以错误的根因修复了 run 33274358974 的失败；当同一心跳子测试在负载下再次抖动时，main CI 会再次变红，而其追踪 issue 已被关闭，不再有任何开放的追踪入口。消抖本身合理且已经 maintainer 验证；缺陷仅在于这一认证。修复方式：将两处正文中的 Fixes #10529 改为非关闭引用，从标题移除 (#10529)，并把过时的正文章节（"What this PR does"、Test Plan 第 3 步、Evidence、Risk）改写为围绕 assert-once 改动的描述——仅 PR 元数据操作，无需代码改动。注意必须同时移除两处正文中的关键字：GitHub 会解析正文任意位置的关闭关键字，只移除一处，认证仍然有效。

Verified as real; escalated — the fix is PR metadata, which this round cannot write.
Confirmed against this checkout, not just the report:
.github/scripts/autofix-status-heartbeat.test.mjs:919is the subteststamps each tick in flight around the gh call and clears it after, andci.yml:739runs it as its ownRun .github/scripts helper testsstep ($HELPER_TESTS,ci.yml:82) ahead of the Vitest step that executes this PR's test. A failure there aborts the job, so the Vitest step is skipped — this change cannot have fixed that run.git diff origin/main...HEAD --statis one file,packages/acp-bridge/src/json-string-bytes.test.ts(+10/-3).grep -rn "10529"over the repo returns nothing, so the certification lives only in the PR title/body on GitHub.
Why no commit: the finding's own remediation is "PR-metadata bookkeeping only, no code change", and @wenshao's round-2 verification says "drop Fixes #10529 (a plain reference is fine). Then merge." The shipped assert-once rewrite is correct and stays as it is. This mode's agent has no GitHub credentials (GITHUB_TOKEN / GH_TOKEN / CI_DEV_BOT_PAT unset), and the review-address path consumes no PR-metadata file — pr-title.txt / pr-body.md are read only by gh pr create in the develop-issue publish job (qwen-autofix.yml:1543-1544); the autofix workflow contains no gh pr edit. So writing them here would produce nothing.
Applying it needs one gh pr edit 10532:
Title, minus the trailing reference:
fix(acp-bridge): deflake the exhaustive UTF-16 byte-estimate test
Both body sections, with the closing keyword removed from each — GitHub parses closing keywords anywhere in the body, so removing one leaves the certification live:
## Linked Issues
Related to #10529 — deliberately **without** a closing keyword. That issue's recorded CI failure was in the `.github/scripts` helper suite `autofix-status-heartbeat.test.mjs` (subtest `stamps each tick in flight around the gh call and clears it after`), run by a separate `Run .github/scripts helper tests` step; in that run the step executing this PR's test was skipped, so this change is not its fix. The issue was closed as stale on 2026-08-31.
Restores the ECS-conditional `testTimeout` knob from #10552 as the authoritative per-test timeout for this package.## 关联 Issue
与 #10529 相关——刻意**不使用**关闭关键字。该 issue 记录的 CI 失败发生在 `.github/scripts` 辅助测试套件 `autofix-status-heartbeat.test.mjs`（子测试 `stamps each tick in flight around the gh call and clears it after`），由独立的 `Run .github/scripts helper tests` 步骤执行；在那次运行中，执行本 PR 测试的步骤被跳过，因此本改动不是它的修复。该 issue 已于 2026-08-31 以 stale 关闭。
恢复了 #10552 中按 ECS 条件生效的 `testTimeout` 开关，使其重新成为本包权威的单测超时。The remaining stale sections the finding names ("What this PR does", Test Plan step 3, Evidence, Risk) still describe the superseded 60s timeout raise. A complete paste-ready replacement body describing the assert-once change that actually ships is in this round's report comment on the PR.
Thread intentionally left open: the finding is not resolved in code, so resolving it would hide an unaddressed Critical.
经复核属实；已上报——修复对象是 PR 元数据，本轮无法写入。
对照当前 checkout 确认（不只是照抄报告）：
.github/scripts/autofix-status-heartbeat.test.mjs:919就是子测试stamps each tick in flight around the gh call and clears it after；ci.yml:739以独立的Run .github/scripts helper tests步骤运行它（$HELPER_TESTS，见ci.yml:82），位于执行本 PR 测试的 Vitest 步骤之前。该步骤失败会中止整个 job，Vitest 步骤因此被跳过——本改动不可能修复那次运行。git diff origin/main...HEAD --stat只有一个文件packages/acp-bridge/src/json-string-bytes.test.ts（+10/-3）。对仓库执行grep -rn "10529"无任何匹配，说明该认证只存在于 GitHub 上的 PR 标题/正文中。
为何没有提交：该发现自身写明的修复方式是 "仅 PR 元数据操作，无需代码改动"，@wenshao 的第 2 轮验证也写明 "drop Fixes #10529 (a plain reference is fine). Then merge."（去掉 Fixes #10529，普通引用即可，然后合入。）实际提交的 assert-once 重写是正确的，保持原样。本模式的 agent 没有任何 GitHub 凭据（GITHUB_TOKEN / GH_TOKEN / CI_DEV_BOT_PAT 均未设置），而 review-address 路径不消费任何 PR 元数据文件——pr-title.txt / pr-body.md 只在 develop-issue 发布 job 的 gh pr create 中被读取（qwen-autofix.yml:1543-1544）；整个 autofix 工作流中没有 gh pr edit。因此在这里写出这两个文件不会产生任何效果。
要落实它，只需一条 gh pr edit 10532：
标题去掉末尾的 issue 引用：
fix(acp-bridge): deflake the exhaustive UTF-16 byte-estimate test
两处正文章节都要移除关闭关键字——GitHub 会解析正文任意位置的关闭关键字，只移除一处，认证仍然有效。（两段替换文本见上方英文区块中的 ## Linked Issues 与 ## 关联 Issue。）
该发现点名的其余过时章节（"What this PR does"、Test Plan 第 3 步、Evidence、Risk）仍在描述已被替换的 60 秒超时上调。一份可直接整段粘贴、描述实际提交的 assert-once 改动的完整替换正文，已放在本轮发到 PR 上的报告评论中。
线程刻意保持开放：该发现并未在代码中被解决，关闭它会掩盖一条未处理的 Critical。

因此 PR 正文中的 Fixes #10529 是一个错误认证：合并记录会声称本改动修复了一个它根本没有触碰的测试套件的失败。
本轮为何没有任何改动
- 该发现自身就写明了修复方式："仅 PR 元数据操作，无需代码改动"，并且 "修复不得回退或重塑代码改动"——维护者 @wenshao 的第 2 轮验证（PR 评论
5509928882）也印证了这一点："dropFixes #10529(a plain reference is fine). Then merge."（去掉Fixes #10529，普通引用即可，然后合入。）消抖本身合理且已经维护者验证，因此去动json-string-bytes.test.ts是错误的。 - 本模式下的 agent 没有任何 GitHub 凭据（环境中
GITHUB_TOKEN、GH_TOKEN、CI_DEV_BOT_PAT均未设置），且被禁止执行网络写操作。 review-address路径不收集任何 PR 元数据文件。pr-title.txt/pr-body.md只在 develop-issue 的发布 job 创建 PR 时被读取（.github/workflows/qwen-autofix.yml:1543-1544的gh pr create）；整个 autofix 工作流中不存在gh pr edit。本轮即使写出这两个文件也不会产生任何效果。
因此该线程被刻意保持开放，并已在其上回复了一份可直接粘贴的替换元数据。这是上报（escalation），不是拒绝（decline）——没有人认定该发现是错的。
维护者需要做的事（一条 gh pr edit）
标题——去掉末尾的 issue 引用：
fix(acp-bridge): deflake the exhaustive UTF-16 byte-estimate test
正文——完整替换，结构与 .github/pull_request_template.md 一致。关闭关键字已从 ## Linked Issues 与 ## 关联 Issue 两处同时移除，因为 GitHub 会解析正文任意位置的关闭关键字。（完整替换正文见上方英文区块内的 markdown 代码块，其中已包含逐段对应的中文翻译与 ## 关联 Issue 小节。）
失败检查的分诊——同样无可执行动作
Test (ubuntu-latest, Node 22.x)、web-shell E2E Smoke、Real daemon E2E / Java 11：状态是 CANCELLED（被取消），不是失败。ci.yml:53-64把 PR 运行放进以 head ref 为键的并发组，并对非main引用启用cancel-in-progress，因此每次新推送——本分支 head75ea637edb就是一个新的Merge branch 'main'提交——都会取代正在进行的运行。这些需要的是重跑，不是代码改动。Post Coverage Comment (ubuntu-latest, 22.x)：FAILURE，且是上述取消的下游结果。该 job 声明needs: [classify_pr, test]并带if: !cancelled()（ci.yml:1405-1421），所以即使test被取消它仍会运行，随后其Download coverage reports artifact步骤找不到coverage-reports-22.x-ubuntu-latest产物。该 job 带continue-on-error: true，因此不会阻塞合并，且在Test正常跑完后自然消失。
两者都无法从 packages/acp-bridge/src/json-string-bytes.test.ts 触及，而 .github/workflows/ci.yml 在本 PR 的足迹之外——评审轮次不得扩张进入它本来并不涉及的 CI 机制。

Flip: broken 3/3 → fixed 3/3 at share5; the threshold crossing itself was caught live at share3 (base distribution straddles the 5s line). Worst head observation at the harshest level: 332 ms — a 15x margin; head's own idle→share5 slowdown ratio is x5.5, so even a doubling of the worst observed contention keeps it under 2s. 12/12 scripted assertions (logs/timing-ab2-run.txt; witness 01-timing-ab-contention-ladder.png, a live re-run of the same harness).
Mechanism note: because the sweep loop is fully synchronous, vitest's 5s timer cannot preempt it; the timeout is enforced at completion (withTimeout/resolve path in @vitest/runner, vitest 3.2.7), which is why timed-out cells read failed with duration ≥ 5000ms, and why the serialized failure shows Error: STACK_TRACE_ERROR — makeTimeoutError() builds "Test timed out in 5000ms" but swaps in the pre-allocated stack-trace error's stack. Same failure the issue quoted; different serialization in the JSON reporter.
2. Mutation A/B across test files (coverage half)
Test-only PR ⇒ the question is whether the rewritten suite still holds down what the old one did. 13 single-point mutants of the unmodified production file json-string-bytes.ts (sha256-identical across both arms: dc8c8864…), each run against the OLD test file (from HEAD^1) and the NEW one, in a scratch worktree; unmutated controls green on both arms; source restored and hash-verified after every mutant.

- No mutant regressed killed→survived going old→new (assertion enforced). Killed/total: 11/13 on both arms.
- Attribution checked per mutant: M1–M4, M6, M7, M13 are killed by the sweep test itself under the new file; M5, M8–M10 are killed by the paired/random tests on both arms — the sweep's single code units take the no-escape fast path around those loop branches, on the old arm exactly as on the new one.
- The 11 killed mutants are the positive control for the 2 survivors (and every mutant's revert was hash-verified, so a green control is meaningful).
- Bounded-report probe (M13): on a 63,360-unit divergence the new test's terminal failure is the count plus exactly 5 sample entries — whole vitest output 4,290 bytes, diff names
"count": 63360and starts at"code": 128(03-m13-bounded-report-terminal.png). The old arm stops at the first divergence (3,640 bytes). The commit's bounded-report claim holds at scale. - 59/59 scripted assertions (logs/mutation-matrix-final.txt; witness
02-mutation-matrix-13-mutants.png).
Targeted gate and Reviewer Test Plan walkthrough
- Gate: full
packages/acp-bridgesuite at HEAD — Test Files 34 passed (34), Tests 1919 passed (1919), exit 0 (logs/gate-head-full-suite.log). The PR body's 1818-test count predates the 12 merges of main into this branch. - Step 1 ("run the file, expect 5/5"): performed — 5/5, tests 255ms on a loaded box (logs/reviewer-step1-head.log).
- Step 2 ("contention: HEAD~1 times out at 5s, this commit passes"): performed and strengthened — the ladder above shows the flip (3/3 → 3/3 at share5) and the crossing at share3; head's margin holds at every rung.
- Step 3 ("confirm the diff is exactly one timeout argument plus a short comment"): cannot be performed as written — the final diff contains no timeout argument at all (see Corrections; the plan text is stale, the code is fine).
Corrections (description vs final code — no code change requested)
- The PR body says the change "Raises the per-test timeout … from vitest's 5s default to an explicit 60s" and that "only the timeout ceiling changes". Neither is true at the merged head. The 60s bump was the first commit; it was replaced by
test(acp-bridge): assert exhaustive byte-estimate sweep once per runprecisely because the bump "silently overrode the ECS-conditional testTimeout knob" (vitest.config.tsalready grants 60s onRUNNER_NAME=ecs-qwen-*runners, 5s elsewhere). Final state: no per-test timeout argument exists (grep-verified, 0 matches), the 5s default stays authoritative, andvitest.config.tsis sha256-identical between base and head. - "No assertion is removed, weakened, or retried" is also stale: the 65,536 per-unit assertions were replaced by one collective assertion. The mutation A/B above is the evidence that catching power is preserved (11/13 killed on both arms, zero regressions) — but the body's characterization should be updated.
- Reviewer Test Plan step 3 quotes a diff that no longer exists (see walkthrough). The body's before/after test counts (1 failed/1817 → 1818) predate 12 merges of main; current suite is 1919 tests.
Findings
F1 — Suggestion, pre-existing: the in-loop limit early-return is unpinned (mutant M11 survives both arms).
The only limit fixture, estimateJsonStringBytes('\u0001'.repeat(100), 20), is intercepted by the top guard (unescapedBytes 102 > 20) before the loop runs; the in-loop if (bytes > limitBytes) return limitBytes + 1; is reachable only via strings whose raw bytes fit the limit but whose escaped bytes exceed it, e.g. estimateJsonStringBytes('\u0001'.repeat(10), 15) → 16 (value verified against the real module). The production behavior is correct; no test pins it, on either arm — so this is completeness reporting, not a merge condition and not introduced by this PR. A fixture asserting .toBe(16) for that input would turn M11 red.
F2 — Suggestion, pre-existing: the exact-limit boundary of the top guard is unpinned (mutant M12 survives both arms).
> vs >= on unescapedBytes > limitBytes diverges exactly at the boundary (e.g. ('ab', 4) → 4 original vs 5 mutant); no test hits it on either arm. Same classification as F1; fixture named above would pin it.
F3 — Nit, informational: vitest 3.2.7 JSON reporter drops the assertion diff.
The sweep's failure summary line (expected { count: 63360, …(1) } to deeply equal { count: +0, first: [] }) is what failureMessages carries; the sample entries ride in the diff, which the default/terminal reporter (i.e. CI logs) renders but the JSON reporter omits. Machine consumers parsing --reporter=json output would see the count but not the samples. No action needed for this PR; recorded because the commit message's "reports which code points diverge" is true for CI logs, not for JSON output.
F4 — Nit, completeness: what the sweep's oracle actually covers.
"matches JSON.stringify UTF-8 bytes for every UTF-16 code unit" is literally true, but for the 63,360 no-escape units the oracle exercises the fast path; the slow loop's multi-byte branches are pinned by the deterministic-random test (M8–M10 attribution, identical on both arms). Not a defect — just the accurate coverage map, useful if anyone later edits either test.
Not covered
- Per-commit attribution: the checkout is depth 2;
git rev-list HEAD^1..HEAD^2shows 1 commit while the metadata snapshot lists 20 (12 of them merges of main). Only the aggregateHEAD^1..HEADdiff (1 file) was verified; individual commit claims (e.g. the intermediate 60s-bump state) were not exercised.git rev-list --countreturning 1 at a shallow boundary is the known false-negative shape, so the gap was established against the snapshot'scommitsarray. - Log-level attribution of CI run 33274358974 to this test — no run logs available in this environment; the PR itself flags this as inferred. The timing A/B proves the mechanism (base breaks the 5s budget under contention), not that this specific run died on this specific test.
- Windows/macOS runners — test-only change, platform-independent logic, not executed there.
- Repo-wide gates — only
packages/acp-bridge(the sole affected workspace) ran. - ECS-runner 60s path — not exercised end-to-end; the config carrying it is byte-identical across arms and untouched by the PR, so its behavior cannot have changed.
- shellcheck/yamllint/actionlint — nothing to run: no shell or YAML in the diff.
- Mutation coverage is 13 targeted single-point mutants, not an exhaustive enumeration of the function's edit space.
- The body's "~29ms verified logic" figure was not isolated; the measured head sweep-test duration (function + oracle) is 36–61ms idle on this box.
Methodology
Environment: CI verify container (node:22-bookworm), 64 cores, Node 22.23.2, vitest 3.2.7, RUNNER_NAME empty so the 5s default timeout applies — same regime as the failing push lane. Arms: tmp/base-tree worktree at HEAD^1, tmp/mutant-tree at the merge commit; the production file under test is sha256-identical across all trees (dc8c8864…) and vitest.config.ts identical base/head (7fd97173…), making the test file the sole variable; worktrees resolve the shared root node_modules (symlinks irrelevant here — the test imports only vitest and its same-dir production file), and both scratch trees were git worktree remove --forced after the A/B cells were captured. Harnesses (timing-ab2.mjs, mutation-matrix.mjs, this dir) drive the compiled vitest stack directly — no stubs of code under test — and every number above is a scripted comparison in their output; raw per-cell vitest JSON/stdout logs live in logs/ (timing2-*, mut-*, m13-*-terminal*, gate-head-full-suite.log, reviewer-step1-head.log, mutation-matrix-final.txt, timing-ab2-run.txt). Images: 01-* is a live re-run of the timing harness under scripts/verify-capture.mjs; 02-* and 03-* are rasterizations of the canonical final logs named above (replayed verbatim, not re-executed, for budget). One harness note: an early version of the M13 probe parsed the JSON reporter's failureMessages for the diff and read it as missing samples; the terminal-reporter repro proved that an oracle artifact, and the final harness probes the default-reporter output CI actually logs.

What this PR does
Raises the per-test timeout of the exhaustive UTF-16 byte-estimation test in the ACP bridge package from vitest's 5s default to an explicit 60s. The test sweeps all 65,536 UTF-16 code units with one assertion per code unit; the verified logic itself runs in ~29ms, so essentially all of its wall time is per-iteration assertion overhead, which exceeds the 5s default whenever the runner is slow or contended. No assertion is removed, weakened, or retried — only the timeout ceiling changes.
Why it's needed
A
Qwen Code CIpush-lane run onmain(run 33274358974, issue #10529) failed before any test result was reported. Reproducing the lane locally on the current main surfaced exactly one failing test: this one, timing out atTest timed out in 5000ms. It is load-dependent: ~3.8–6.5s on an idle machine, over 5s under CPU contention — a standing flake source on the shared CI runner pool, where a slow or killed vitest run is also what produces the run's "no test result" shape. This removes the only test failure reproducible on main.Reviewer Test Plan
How to verify
cd packages/acp-bridge && npx vitest run src/json-string-bytes.test.ts— expect 5/5 tests passing; the exhaustive sweep test should complete in single-digit seconds.for i in $(seq 1 $(($(nproc)/2))); do node -e "while(true){}" & done) and run the test atHEAD~1(times out at 5s) versus this commit (passes with a wide margin). Reviewers without spare cores can take the recorded probe evidence in the E2E report.Evidence (Before & After)

xzbinary and unwritable linter cache); no shell or YAML files are touched by this change. The original CI run's logs were not readable by the agent, so attribution of run 33274358974 to this exact test is inferred from local reproduction, not proven from the run itself; runner-infrastructure causes are outside any code fix.Linked Issues

中文说明
本 PR 做了什么
将 ACP bridge 包中穷举 UTF-16 字节估算测试的单测超时从 vitest 默认的 5 秒提高到显式的 60 秒。该测试以每个码元一次断言的方式扫描全部 65,536 个 UTF-16 码元；被验证的逻辑本身只需约 29ms，因此其墙上时间几乎全部来自逐次断言的开销，只要运行器较慢或存在争用就会超过 5 秒默认值。没有删除、放宽或重试任何断言——只改变超时上限。
为什么需要
main上的一次Qwen Code CIpush 通道运行（run 33274358974，issue #10529）在任何测试结果上报之前失败。在当前 main 上本地复现该通道时，恰好只发现一个失败的测试：就是这个测试，以Test timed out in 5000ms超时。它是负载相关的：空闲机器上约 3.8–6.5 秒，CPU 争用时超过 5 秒——这是共享 CI 运行器池上的一个长期抖动来源；在那里，变慢或被杀掉的 vitest 运行也正是产生该次运行"无测试结果"形态的原因。本改动消除了 main 上唯一可复现的测试失败。评审者测试计划
如何验证
cd packages/acp-bridge && npx vitest run src/json-string-bytes.test.ts——预期 5/5 测试通过；穷举扫描测试应在数秒内完成。for i in $(seq 1 $(($(nproc)/2))); do node -e "while(true){}" & done），分别在HEAD~1（5 秒处超时）与本提交（以宽裕余量通过）上运行该测试。没有空闲核心的评审者可参考 E2E 报告中记录的探针证据。证据（前后对比）
N/A（非 UI 改动）。测试证据：改动前——
packages/acp-bridge中Test Files 1 failed | 33 passed、Tests 1 failed | 1817 passed，目标测试报Error: Test timed out in 5000ms；改动后——Test Files 34 passed、Tests 1818 passed，目标测试在约 50% 核心负载下约 8 秒通过，且 3/3 次独立重跑通过。测试平台
环境（可选）
仅单元测试（
npx vitest run），Node 22，自托管 Linux 运行器。不涉及 CLI/沙箱执行。风险与范围
xz二进制、linter 缓存目录不可写）；本改动未触碰任何 shell 或 YAML 文件。agent 无法读取原 CI 运行的日志，因此将 run 33274358974 归因于这个具体测试是基于本地复现的推断，而非来自运行本身的证明；运行器基础设施类原因不在任何代码修复的范围之内。关联 Issue
