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:919 is the subtest stamps each tick in flight around the gh call and clears it after, and ci.yml:739 runs it as its own Run .github/scripts helper tests step ($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 --stat is 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。

expect(estimateJsonStringBytes(value, Number.MAX_SAFE_INTEGER)).toBe(
Buffer.byteLength(JSON.stringify(value)),
);
}
});
}, 60_000);

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:

  1. 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.sh is the autofix round status-comment heartbeat, launched and killed by qwen-autofix.yml itself), and the deterministic footprint gate rejects rounds expanding outside this PR's packages/acp-bridge footprint. Feedback requesting such a change is escalated to a maintainer, not implemented.
  2. 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 commit a623924a80, 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.

中文说明

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:

  1. 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 PR packages/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。
  2. 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。

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:

  1. 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.sh is the autofix round status-comment heartbeat, launched and killed by qwen-autofix.yml itself), and the deterministic footprint gate rejects rounds expanding outside this PR's packages/acp-bridge footprint. 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.
  2. 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 commit a623924a80, 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.

处置:已升级给维护者——第 2 轮的复核证据已确认,但两种补救方式机器人均无法实施,因此本线程保持打开。

本轮已在本地代码树上独立确认第 2 轮的证据:git diff 02f2101f43..HEAD -- .github/scripts/ 为空(自事故提交以来心跳套件未被触碰);失败子测试 stamps each tick in flight around the gh call and clears it after 在 HEAD 上正如引用所述位于 .github/scripts/autofix-status-heartbeat.test.mjs:866;本 PR 的全部差异就是 acp-bridge 的超时上调。Fixes #10529 认证在 HEAD 上依然是错误的。

本轮为何不实施任何一种补救方式:

  1. 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 PR packages/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。此外,第 2 轮给出的验收标准(放宽新容忍度并确认子测试变红)还需要在恰恰该受保护区域内对时序抖动做负载受控复现。
  2. 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;本轮已在 HEAD 上复核为绿:5/5 测试,穷举扫描约 2.6 秒),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(保持该 issue 的标准:不删除、不放宽、不重试任何断言)?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。

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...HEAD is still only the acp-bridge timeout raise (+4/−1 in packages/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 8s waitFor budget 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 Test job died at its 60-minute cap (timeout-minutes: 60 on the ci.yml test job; the job ran 61m06s and concluded CANCELLED) with no test result, and Post Coverage Comment failed 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:

  1. 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's packages/acp-bridge footprint; 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.
  2. 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 edit anywhere in qwen-autofix.yml; pr-body.md is consumed only at PR creation), and the (#10529) title reference sits in already-pushed commit a623924a80 while 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.

中文说明

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:

  1. 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 PR packages/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。
  2. 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。

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...HEAD still 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.mjs is empty, and the file's last change (6cd0cc7869) is an ancestor of the incident commit. The cited subtest is still at line 866, the waitFor(..., 8000) budget at line 883, the assertion expected at least two PATCH calls with stamp observations at 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.

中文说明

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。

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...HEAD still 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.mjs is empty; the file's last change (6cd0cc7869) is an ancestor of 02f2101f43. The cited subtest is still at line 866, the waitFor(..., 8000) budget at line 883, the assertion expected at least two PATCH calls with stamp observations at line 887.
  • ci.yml still 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。

Disposition: still escalated to a maintainer — round-6 re-verification confirms the finding at the post-merge HEAD; neither remediation is implementable by this loop, so the thread stays open.

Re-verified at post-merge HEAD 66882c2c55 (merge of origin/main into this branch):

  • git diff origin/main...HEAD still touches exactly one file, packages/acp-bridge/src/json-string-bytes.test.ts (+4/−1, a timeout ceiling raise only). No round has ever touched .github/.
  • The heartbeat suite is still byte-identical to the incident commit — the merge brought in #10602 (sdk bundle budget) and #10146 (OpenTUI scaffolding), neither of which touches .github/scripts/autofix-status-heartbeat.test.mjs. The cited subtest is still at line 866 with the waitFor(..., 8000) budget at line 883 and the expected at least two PATCH calls with stamp observations assertion.

New this round — root cause of the five red checks, fixed by merging main. Run 33354030402 (03:30Z) failed while main itself was red: #10571 grew the browser daemon SDK bundle to 220,220 bytes, past the 215KB budget in packages/sdk-typescript/scripts/build.js, so npm run build failed on every PR until #10602 bumped the budget to 216KB (merged 05:00Z, ~1.5h after our run). Reproduced at the pre-merge branch state: Error: Browser daemon SDK bundle is 220220 bytes; expected <= 220160. That build failure explains Test (ubuntu-latest, Node 22.x) and Integration Tests (no-AK, No Sandbox) (both failing ~7 min, in the build phase), Real daemon E2E / Java 11 (boots the daemon from the TS SDK build; the same workflow's plain Java jobs passed without it), and the two downstream jobs that start only after Test (web-shell E2E Smoke, Post Coverage Comment). The round-6 review harness independently hit the same budget failure. This round merged origin/main (commit 66882c2c55, no conflicts) so the branch state builds green again; the changed test itself is unaffected (5/5 at the previous HEAD, re-run this round — see the round summary's Verification section). None of this alters the finding below.

Why nothing was implemented for the finding itself: 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 feedback requesting such a change is escalated, not implemented, regardless of author. Option B (unlink) requires editing the PR body and rewriting an already-pushed commit title; this loop is additive-commits-only and holds no GitHub credentials (gh auth status: not logged in).

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), 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.

处置:继续升级给维护者——第 6 轮复核在合并后的 HEAD 上确认该发现仍然成立;两种补救方式本循环均无法实施,因此线程保持打开。

已在合并后的 HEAD 66882c2c55(origin/main 合入本分支)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)。任何一轮都未曾触碰 .github/。
  • 心跳套件与事故提交仍然逐字节一致——本次合并带入了 #10602(sdk 包体预算)与 #10146(OpenTUI 脚手架),两者均未触碰 .github/scripts/autofix-status-heartbeat.test.mjs。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 仍在原处。

本轮新进展——五个红色检查的根因,已通过合并 main 修复。 运行 33354030402(03:30Z)失败时 main 本身是红的:#10571 将浏览器 daemon SDK 包体增大到 220,220 字节,超出 packages/sdk-typescript/scripts/build.js 中 215KB 的预算,导致 npm run build 在每个 PR 上都失败,直到 #10602 将预算提高到 216KB(05:00Z 合入,比本次运行晚约 1.5 小时)。已在合并前的分支状态本地复现:Error: Browser daemon SDK bundle is 220220 bytes; expected <= 220160。该构建失败解释了 Test (ubuntu-latest, Node 22.x) 与 Integration Tests (no-AK, No Sandbox)(均约 7 分钟在构建阶段失败)、Real daemon E2E / Java 11(需从 TS SDK 构建产物启动 daemon;同一 workflow 中不依赖它的纯 Java job 均通过),以及两个在 Test 之后才启动的下游 job(web-shell E2E Smoke、Post Coverage Comment)。第 6 轮审查的构建阶段也独立命中了同一预算失败。本轮已合并 origin/main(提交 66882c2c55,无冲突),分支状态恢复可构建;被改动的测试本身不受影响(上一 HEAD 5/5,本轮复跑见回合摘要的 Verification 一节)。以上均不改变下述发现本身。

为何未就该发现本身实施任何修改: 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,对此类修改的反馈无论来自谁一律升级而非实施。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;本循环只允许增量提交且不持有任何 GitHub 凭据(gh auth status:未登录)。

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),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。

Disposition: still escalated to a maintainer — the round-7 re-verification is independently confirmed at HEAD 50447e2307; neither remediation is implementable by this loop, so this thread stays open.

Re-verified this round at HEAD 50447e2307 (the only change since the HEAD your round assessed is an additive merge of current main):

  • git diff origin/main...HEAD still touches exactly one file, packages/acp-bridge/src/json-string-bytes.test.ts (+4/−1 — a timeout ceiling raise from vitest's 5s default to 60_000, plus one comment; no assertion touched). No round has ever touched .github/.
  • The heartbeat suite is still byte-identical to the incident commit: git log 02f2101f4305..HEAD -- .github/scripts/autofix-status-heartbeat.test.mjs is empty. The failing subtest stamps each tick in flight around the gh call and clears it after is at line 866, its waitFor(..., 8000) budget at line 883, and the expected at least two PATCH calls with stamp observations assertion at line 887. Your round's step-metadata evidence (helper-tests step failure, vitest step skipped) matches that tree state: the deflaked test never ran in run 33274358974, so the Fixes #10529 certification is wrong, exactly as stated. The finding is real and is not declined; the deflaked test itself passes at this HEAD (5/5, sweep 921ms).

Why nothing was implemented: both remediations remain outside this loop's reach, as in every prior round. 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 feedback requesting such a change is escalated, not implemented, regardless of author; the deny-by-default footprint gate would also reject the round. Option B (unlink) requires editing the PR body and rewriting an already-pushed commit title; this loop is additive-commits-only and holds no GitHub credentials.

Question for the maintainer (open since round 1): (a, recommended) edit the PR body to drop Fixes #10529 and merge this as a standalone, separately-evidenced deflake, keeping #10529 open to track the heartbeat failure; or (b) close this PR and deflake 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); or (c) merge as-is, accepting the residual risk that auto-closes #10529 while the heartbeat failure remains live in the tree — the option this loop would not pick. The verified heartbeat flake is re-recorded in this round's deferred-findings.json so it reaches the follow-up queue whichever option is chosen.

处置:继续升级给维护者——第 7 轮的复核已在 HEAD 50447e2307 上独立确认;两种补救方式本循环均无法实施,因此本线程保持打开。

本回合已在 HEAD 50447e2307 上复核(相对你所在轮次评估的 HEAD,唯一变化是一次增量合并当前 main 的 merge):

  • 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——仅将超时上限从 vitest 默认的 5 秒提高到 60_000,外加一条注释;未触碰任何断言)。任何一轮都未曾触碰 .github/。
  • 心跳套件与事故提交仍然逐字节一致:git log 02f2101f4305..HEAD -- .github/scripts/autofix-status-heartbeat.test.mjs 为空。失败子测试 stamps each tick in flight around the gh call and clears it after 位于第 866 行,其 waitFor(..., 8000) 预算在第 883 行,断言 expected at least two PATCH calls with stamp observations 在第 887 行。你所在轮次的步骤元数据证据(helper-tests 步骤 failure、vitest 步骤 skipped)与该代码树状态一致:被消抖的测试在 run 33274358974 中从未执行,因此 Fixes #10529 的认证是错误的——与发现的陈述完全一致。该发现属实、不予拒绝;被消抖的测试本身在该 HEAD 上通过(5/5,sweep 921ms)。

为何未实施任何修改: 与之前每一轮相同,两种补救方式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,对此类修改的反馈无论来自谁都一律升级而非实施;默认拒绝的足迹门禁同样会拒绝这样的回合。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;本循环只允许增量提交且不持有任何 GitHub 凭据。

给维护者的问题(自第 1 轮起开放): (a,推荐) 编辑 PR 正文移除 Fixes #10529,将本改动作为另有独立证据的单独消抖合入,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);或 (c) 按现状合入并接受残余风险——那样会在心跳失败仍留在代码树中的情况下自动关闭 #10529——这是本循环不会选择的选项。已被证实的心跳抖动已重新记入本轮的 deferred-findings.json,无论选择哪个方案都会进入后续处理队列。

Disposition: still escalated to a maintainer — the round-8 re-verification (now from the run's raw job log) is independently confirmed at HEAD 50447e2307; neither remediation is implementable by this loop, so this thread stays open.

Re-verified this round at HEAD 50447e2307 — exactly the HEAD your round assessed; the tree has not moved since:

  • git diff origin/main...HEAD still touches exactly one file, packages/acp-bridge/src/json-string-bytes.test.ts (+4/−1 — a timeout ceiling raise from vitest's 5s default to 60_000, plus one comment; no assertion touched). No round has ever touched .github/.
  • The heartbeat suite is still byte-identical to the incident commit: git log 02f2101f4305..HEAD -- .github/scripts/autofix-status-heartbeat.test.mjs is empty. The failing subtest stamps each tick in flight around the gh call and clears it after is at line 866, its waitFor(..., 8000) budget at line 883, and the expected at least two PATCH calls with stamp observations assertion at line 887. Your raw job log this round (not ok 17 - autofix-status-heartbeat loop at :215:1, subtest not ok 18 at :866:3, TAP # tests 489 / # pass 488 / # fail 1, vitest step skipped) is consistent with that tree state: the test this PR deflakes never ran in run 33274358974, so the Fixes #10529 certification is wrong, exactly as stated. The finding is real and is not declined; the deflaked test itself passes at this HEAD (5/5, sweep 921ms).

Why nothing was implemented: both remediations remain outside this loop's reach, as in every prior round. 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 feedback requesting such a change is escalated, not implemented, regardless of author; the deny-by-default footprint gate would also reject the round. Option B (unlink) requires editing the PR body and rewriting an already-pushed commit title; this loop is additive-commits-only and holds no GitHub credentials.

Agreement recorded: your comment concedes "neither remediation is implementable by the bot loop — this remains a maintainer decision", and both round-7/8 review bodies recommend land-with-residual-risk — the exit is a maintainer risk-acceptance decision, not another review round. This loop concurs; there is no further code action available to it for this finding.

Question for the maintainer (open since round 1): (a, recommended) edit the PR body to drop Fixes #10529 and merge this as a standalone, separately-evidenced deflake (the E2E report's local reproduction; triage confidence 5/5), keeping #10529 open to track the heartbeat failure; or (b) close this PR and deflake the heartbeat suite under #10529 as maintainer-owned work — timing budget only (the subtest requires two stamped ticks inside an 8s waitFor; under load that budget is the flake surface), no assertion removed, weakened, or retried; acceptance criterion: relax the new tolerance again and confirm the subtest goes red; or (c) merge as-is, accepting the residual risk (auto-closes #10529 while the heartbeat failure remains live in the tree) — the option this loop would not pick. The verified heartbeat flake is re-recorded in this round's deferred-findings.json so it reaches the follow-up queue whichever option is chosen.

处置:继续升级给维护者——第 8 轮的复核(本轮已取自该运行的原始任务日志)已在 HEAD 50447e2307 上独立确认;两种补救方式本循环均无法实施,因此本线程保持打开。

本回合已在 HEAD 50447e2307 上复核——与你所在轮次评估的 HEAD 完全相同,此时代码树未再变动:

  • 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——仅将超时上限从 vitest 默认的 5 秒提高到 60_000,外加一条注释;未触碰任何断言)。任何一轮都未曾触碰 .github/。

Disposition: escalated to a maintainer — verified real at HEAD 964fb72a, not implementable by this loop; thread left open.

Re-verified this round at the exact HEAD review round 11 assessed:

  • git diff origin/main...HEAD still touches exactly one file, packages/acp-bridge/src/json-string-bytes.test.ts (+4/−1: the 5s→60s timeout raise plus a why-comment). git diff origin/main...HEAD --stat -- .github/ is empty — no round has ever touched .github/.
  • Both heartbeat files are byte-identical to the incident commit: git diff 02f2101f43 HEAD -- .github/scripts/autofix-status-heartbeat.test.mjs .github/scripts/autofix-status-heartbeat.mjs is empty. The cited subtest sits at .github/scripts/autofix-status-heartbeat.test.mjs:866 and the cited assertion expected at least two PATCH calls with stamp observations at :887.
  • One witness correction for the record (same drift round 4 noted): at the current HEAD the directory-level git diff 02f2101f43..HEAD -- .github/scripts/ is not empty — unrelated files changed since (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); the file-scoped witness above is empty, so the finding's substance is unchanged.
  • The GitHub-side facts in the witness (issue closed as stale at 2026-08-31T12:27:02Z; run 33274358974 / job 99165081177 raw log; the PR body keyword) are not independently verifiable from this runner — it holds no GitHub credentials (gh auth status → not logged in). They rest on this round's fetched witness and are consistent with every round's observation since round 1; the load-bearing conclusion — the diff does not address the failure the issue recorded — is fully verified locally.

Why this stays a maintainer decision: the recommended remediation — dropping Fixes #10529 and the (#10529) title reference — is a PR-metadata edit. This loop holds no GitHub credentials (verified this round), the address-review workflow path has no PR-title/body edit mechanism (re-verified in qwen-autofix.yml), history rewriting is forbidden (the commit-title reference sits in already-pushed a623924a; additive commits only), and the head branch name is workflow-owned. The alternative — retargeting the heartbeat suite — is maintainer-owned work in the protected .github/ area, and the maintainer's stale-closure of #10529 ("The lane now passes on the current main") argues against it being wanted.

The standalone deflake itself remains valid and green: at HEAD 964fb72a, npx vitest run src/json-string-bytes.test.ts in packages/acp-bridge passes 5/5 (exhaustive sweep ~1.5s against the new 60s ceiling), and every CI lane at this HEAD is SUCCESS.

Question for the maintainer (open since round 1, now narrowed):
(a, recommended — this finding's own recommendation) edit the PR body to drop Fixes #10529 (rewording the title's (#10529) at merge time if desired) and merge as a standalone, separately-evidenced deflake; or
(b) close this PR.
The former option of keeping #10529 open for a heartbeat-suite deflake is superseded by the stale-closure; a heartbeat flake recurring on current main should be tracked fresh.

处置:升级给维护者——已在 HEAD 964fb72a 上核实属实,但本循环无法实施;线程保持打开。

本回合已在第 11 轮评审所评估的同一 HEAD 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/−1:5 秒→60 秒的超时上调及一条原因注释)。git diff origin/main...HEAD --stat -- .github/ 为空——任何一轮都未曾触碰 .github/。
  • 两个心跳文件与事故提交逐字节一致:git diff 02f2101f43 HEAD -- .github/scripts/autofix-status-heartbeat.test.mjs .github/scripts/autofix-status-heartbeat.mjs 为空。引用的子测试位于 .github/scripts/autofix-status-heartbeat.test.mjs:866,引用的断言 expected at least two PATCH calls with stamp observations 位于 :887。
  • 证据记录的一处更正(与第 4 轮指出过的同一处漂移):在当前 HEAD 上,目录级 git diff 02f2101f43..HEAD -- .github/scripts/ 并不为空——此后有无关文件变动(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);上文文件级证据为空,该发现的实质不变。
  • 证据中的 GitHub 侧事实(issue 于 2026-08-31T12:27:02Z 作为过期关闭;run 33274358974 / job 99165081177 原始日志;PR 正文关键字)无法在本运行器上独立核实——本运行器不持有 GitHub 凭据(gh auth status → 未登录)。这些事实依据本轮获取的证据,且与自第 1 轮以来每一轮的观察一致;承重结论——本 diff 并未处理该 issue 所记录的失败——已在本地完全验证。

为何仍属维护者决策:推荐的补救方式——移除 Fixes #10529 与标题中的 (#10529) 引用——是对 PR 元数据的编辑。本循环不持有 GitHub 凭据(本轮已验证);address-review 工作流路径没有修改 PR 标题/正文的机制(已再次核实 qwen-autofix.yml);禁止重写历史(提交标题引用位于已推送的 a623924a;只允许追加式提交);head 分支名归工作流管理。备选方案——重新对准入心跳套件——属于受保护 .github/ 区域中维护者的工作,且维护者将 #10529 作为过期关闭("该通道在当前 main 上已通过")说明并不希望这样做。

独立消抖本身仍然有效且为绿:在 HEAD 964fb72a 上,packages/acp-bridge 中 npx vitest run src/json-string-bytes.test.ts 5/5 通过(穷举扫描约 1.5 秒,远低于新的 60 秒上限),该 HEAD 的所有 CI 通道均为 SUCCESS。

给维护者的问题(自第 1 轮起开放,现已收窄):
(a,推荐——即该发现自身的建议)编辑 PR 正文移除 Fixes #10529(如愿意,合并时改写标题中的 (#10529)),作为另有独立证据的单独消抖合入;或
(b)关闭本 PR。
此前"让 #10529 保持打开以消抖心跳套件"的选项已被过期关闭取代;心跳抖动若在当前 main 上再次出现,应作为新报告追踪。

Confirmed — agreed, and acted on as far as this bot can reach with an additive commit. The false certification had three carriers: the PR body (Fixes #10529), the PR title ((#10529)), and the original commit title. This round removes the carrier an additive commit controls: the timeout raise itself is gone — the PR's net diff against main is now solely the assert-once deflake (commit 3f56e9a8c7, maintainer @wenshao's "arm C" from the verification report), which carries no timeout change and no (#10529) reference. Verified at HEAD: the sweep still runs all 65,536 comparisons (mutation probe: a lone-surrogate 6→3 mutant is killed with all 1024 divergent code points reported), full acp-bridge suite 34 files / 1898 tests green.

The remaining fix is GitHub metadata this bot cannot write (no credentials in this path): a maintainer please gh pr edit — suggested wording: title test(acp-bridge): deflake the exhaustive UTF-16 byte-estimate sweep; body: replace Fixes #10529 with a plain reference, e.g. "Follow-up to the CI failure recorded in #10529 (closed as stale — the recorded failure was the unrelated .github/scripts heartbeat flake, tracked in #10547). This change removes the root cause of the sweep's contention timeouts rather than raising its timeout." Leaving this thread open until the title/body linkage is dropped.

已确认——认同该发现,并已在本机器人通过追加式提交所能触及的范围内处理。该错误认证有三个载体:PR 正文(Fixes #10529)、PR 标题((#10529))以及原始提交标题。本轮移除了追加式提交所能控制的那个载体:超时上调本身已被移除——本 PR 相对 main 的净 diff 现在只是"只断言一次"的消抖(提交 3f56e9a8c7,即维护者 @wenshao 验证报告中的"臂 C"),不含任何超时改动,也不含 (#10529) 引用。已在 HEAD 上验证:扫描仍执行全部 65,536 次比较(变异探针:孤立代理项 6→3 变异体被杀死,并报告全部 1024 个不一致码点),acp-bridge 全套件 34 个文件 / 1898 个测试通过。

剩余修复是本机器人无法写入的 GitHub 元数据(此路径无凭据):请维护者执行 gh pr edit——建议措辞:标题 test(acp-bridge): deflake the exhaustive UTF-16 byte-estimate sweep;正文:将 Fixes #10529 替换为普通引用,例如"Follow-up to the CI failure recorded in #10529 (closed as stale — the recorded failure was the unrelated .github/scripts heartbeat flake, tracked in #10547). This change removes the root cause of the sweep's contention timeouts rather than raising its timeout."。在标题/正文关联被移除之前,本线程保持打开。
