feat(review): skip the automatic round when a synchronize only refreshes the base#10116wenshao wants to merge 21 commits into
Conversation
…hes the base An update-branch base refresh fires synchronize like any push, so the automatic review spent a full multi-hour round on a head whose PR-side diff was unchanged. A new gate in the review job certifies that shape deterministically — every first-parent commit since the head the last ledger-marked review covered must be a two-parent merge of the base branch, and the PR's own three-dot diff must keep the same patch-id — and then skips the review-spending steps, posting one marker-deduped note instead. Every probe failure or unmatched shape fails open into the full round, and the step never fails the job, so the fallback comment cannot misreport a skip as a pipeline failure. Closes #10111

The workflow size ratchet rejected the inline step (+8.7KB against a 4KB allowance). The gate's bash now lives in its own script — which the tests execute directly, so the executed cases run the exact file CI runs — and the skip note reuses the shared marker upsert helper instead of a hand-rolled dedup, dropping the workflow growth back inside the allowance.

Thanks for the PR! Template looks good ✓ (re-run — gate findings re-confirmed at the new head) Problem: observed, not theoretical. Linked issue #10111 documents two base refreshes on PR #9729 spending one full ~3.5h round plus one cancelled round for zero PR-side change — both cited runs verified via the API (run 32674762912 completed a full round on 2026-08-23, run 32875478404 was cancelled on 2026-08-25). Direction: aligned. This is the repo's own review automation spending multi-hour rounds on pushes whose PR-side delta is zero; a deterministic, fail-open skip gate is the right shape of fix. CHANGELOG: no direct reference — CI-internal behavior with no user-visible surface. Size: no core-package paths ( Approach: scope still feels right on re-run. The gate certifies shape (every first-parent commit since the last ledger-marked reviewed head is a two-parent merge of the base) AND content (digest equality of the PR-side three-dot diff) before skipping, fails open on every probe, and leaves explicit review triggers untouched. The tightening commit Risk: no elevated risk signals — no changed file matches the revert-correlated paths.

Confidence: 4/5 — clean fail-open design; the maintainer's two Criticals are closed with pinning tests; approval deferred only until CI lands green on this head (the two named nits are non-blocking). Stepping back: my independent proposal for this problem was exactly what the PR builds — a precheck that certifies the push is a pure chain of base merges since the last reviewed head, compares the PR-side diff by content digest, and gates the review-spending steps — so the approach matches rather than surprises. The problem is real (both cited runs verified through the API, not just the issue text), and the motivation is concrete: hours of review compute spent on zero PR-side delta. What this re-run added: the maintainer's self-review found two genuine holes in the previous revision — an unsubmitted or dismissed bot review could certify a skip, and the whitespace-blind patch-id would have certified an indentation-only rewrite of PR-owned lines — and the tightening commit closes both the right way: an allow-list of submitted, currently-valid review states, and a whitespace-sensitive digest that strips only hunk offsets and index metadata. Each fix carries a fixture that breaks if the fix is reverted. The three suggestions (octopus coverage, full-expression wiring assertions, direct-execution harness) are in the same commit. My own audit found nothing further that blocks: the fail-open contract holds end to end, the rest of the job is skip-safe, and the residual risk the PR names — an unchanged PR diff interacting semantically with new base code — is inherent to any skip scheme, disclosed, and bounded by the always-available If this lands, a base refresh stops costing a multi-hour round, and the gate's own failure mode is always "run the full round anyway". The prior revision ran the full suite green; the in-flight run on this head is proving the tightening commit's new fixtures. I'll merge it once that lands.

Reviewed head 21cce5f5. Nothing blocking; one non-blocking note inline.
Verified:
- Certification chain holds at this head: foreign-account, unmarked, PENDING, and DISMISSED reviews can never supply the reviewed head (
user.loginfiltered against the livegh api userlogin before state/marker checks); a riding real commit, octopus merge, non-base merge, force-push, and any PR-side diff change (whitespace included — the digest keeps every content byte, stripping onlyindexand@@lines) all fall open to the full round. - Fail-open contract is exhaustive: every probe is
|| returnwith pre-initialized outputs; jq/gh failures yield an emptyREVIEWED_SHAand return; even a${VAR:?}trip is absorbed bycontinue-on-error: trueplus theskip != 'true'comparison reading''when outputs are unset. - Wiring checked at head: all four review-spending steps carry the exact guard expression, and the unguarded downstream steps stay inert under
skip=true(docs-only relay requiressteps.review.outcome == 'success'; the fallback comment requiresfailure(), which skipped steps don't produce). - Ran the gate suite locally at the PR head (
vitest -t 'base-refresh'): 15/15 pass.

Approving. Re-verified all six findings at head 21cce5f: both Criticals (PENDING/DISMISSED certification, patch-id whitespace insensitivity) and all three Suggestions (octopus fixture, full-expression guard assertions, exec-bit contract) are fixed with tests; the P3 null-body note is unreachable and fails open. CI green, sandboxed verification passed.
…eviews (#10116) A review submitted without a body arrives as `"body": null`, and jq's `contains` errors on null — aborting the whole ledger lookup so every later round fails open and the gate can never skip that PR again. Coerce the null to an empty string in the marker filter. Also pin the walk cap (<=10) and the new-commit guard (>=1), which had no tests.

[Critical] R4-2: [certifies-falsely] [new-surface] The gate's base identity is the ref NAME only (the check at lines 125-128); a rewrite of the same-named base branch since the reviewed round slips through the certification and flips a review-deserving synchronize into skip=true. Both merge bases are recomputed against the rewritten live base (this line and the mb_r/mb_h lines below), so digest equality holds by construction while the landed three-dot diff GAINS content the reviewed round never saw: round R reviews head against main tip C (the marker records base: "main" once the writer ships); a maintainer resets main backward (incident revert of a bad commit) and advances with different commits; the author hits update-branch — a plain two-parent merge whose second parent is an ancestor of the rewritten main; the walk passes and digest(mb(main_now, R)) == digest(mb(main_now, H)), so skip=true while the effective PR-side diff contains the dropped commit's content, riding back into main through this PR with no automatic round ever covering it. The retarget defence does not transfer: it catches a ref rename, not a same-name rewrite. Latent only until the marker writer emits base (the R2-4 gap), then live.
Witness:
probe, real git + stubbed gh (marker carrying sha=R and base=main), unmodified gate:
[rewrite] skip=true, reason= — landed three-dot diff gains c1.txt | 1 +
(content the reviewed round saw as BASE, now riding back as PR content)
[normal] skip=true — monotonic advance still skips
fix model (marker records the reviewed base COMMIT + gate ancestor check):
[rewrite] skip=false, reason=reviewed base commit no longer on the base branch
[normal] skip=true
Fix: no gate-only fix exists — record the base COMMIT the round reviewed against (its merge-base) in the ledger marker alongside base (writer half, pairs with R2-4), and require here that it is still an ancestor of the live base tip, failing open otherwise; monotonic advance keeps skipping, any rewrite fails open:
git merge-base --is-ancestor "${REVIEWED_BASE_SHA}" "origin/${BASE_REF}" 2>/dev/null || returnFix constraint: the fix requires the writer-side change from R2-4 (the marker carries no base commit today); the new field rides inside LEDGER_MAX_BYTES = 8192 (packages/cli/src/commands/review/lib/ledger.ts:546) and must follow the anchor pair's withholding semantics (ledger.ts:657-666).
Fix witness: add an executed rebased_base shape — after the round reviews R, reset the origin base backward, add a commit, merge into the PR branch, assert skip=false; the current script returns skip=true for this shape, so the test is red today and pins the ancestor check once added (removing the check must turn it red again).
中文说明
R4-2：[certifies-falsely] [new-surface] 门对 base 的认证只认分支名字（125-128 行的检查）；已评审轮次之后同名 base 分支被重写，可以穿过认证、把本应评审的 synchronize 翻转为 skip=true。两个 merge-base（本行与下方的 mb_r/mb_h）都相对重写后的活 base 重算，因此摘要等式按构造成立，而落地的三点 diff 却新增了已评审轮从未见过的内容：轮次 R 在 main 顶端 C 评审 head（写入端落地后标记记录 base: "main"）；维护者把 main 向后重置（事故回滚坏提交）并以不同提交继续；作者点 update-branch——普通双亲合并、第二亲本是重写后 main 的祖先；行走通过且两侧摘要相等——skip=true，而对活 base 的有效 PR 侧 diff 此时包含被丢弃提交的内容，借由本 PR 回到 main，没有任何自动轮覆盖过它。改道（retarget）防御无法迁移到本形态：它拦的是分支改名，不是同名重写。当前仅在标记写入端补齐 base（R2-4 缺口）之前处于潜在状态，之后即为活通道。
证据：见英文部分（重写分支 skip=true 且落地 diff 新增 c1.txt；正常前进分支 skip=true；修复模型下重写分支翻转为 skip=false）。
修复：不存在仅门侧的修复——在台账标记中与 base 一并记录该轮评审所用的 base 提交（其 merge-base，写入端一半，与 R2-4 配对），并在门中要求它仍是活 base 顶端的祖先，否则向开放侧倒；单调前进照常跳过，任何重写都向开放侧倒（见英文代码片段）。
修复约束：该修复依赖 R2-4 的写入端改动（当前标记不携带 base 提交）；新字段位于 LEDGER_MAX_BYTES = 8192（packages/cli/src/commands/review/lib/ledger.ts:546）的字节预算内，并须遵循锚点对的扣留语义（ledger.ts:657-666）。
修复见证：新增执行形态 rebased_base——轮次评审 R 之后，把 origin base 向后重置、追加一个提交、合入 PR 分支，断言 skip=false；当前脚本对该形态返回 skip=true，因此该测试今天即为红，加入祖先检查后即被钉住（移除该检查必须再次变红）。

Deferred to the follow-up queue — verified real, pairs with R2-4 (same disposition as this finding's sibling threads). The rewrite arm reproduces skip=true on the shipped script while the landed diff gains the dropped commit's content; the fix requires the writer-side base-commit field (outside this PR's footprint, packages/cli) plus the gate-side ancestor check. Both are recorded for the follow-up queue and ship together.

[Critical] R5-1: [certifies-falsely] [new-surface] The hardening this script applies to its git invocations is channel-by-channel — --no-ext-diff --no-textconv on the digest, GIT_NO_REPLACE_OBJECTS=1 globally — but the surface it closes is unbounded: git state planted (or legitimately present) in the reused self-hosted workspace, the exact threat model the header names. Five entrances were probe-verified again this round; all fire at fetch time, BEFORE the ledger lookup, on every matching automatic synchronize, regardless of marker state — live today, not latent. A planted remote.origin.uploadpack turns this fetch and its sibling at line 92 into arbitrary code execution inside a step holding GH_TOKEN: secrets.CI_BOT_PAT — git spawns the planted program via sh -c "<uploadpack> '<url>'" despite GIT_NO_REPLACE_OBJECTS=1/--no-tags/--quiet, the fetch then fails and the gate fails open, so the compromise is invisible in the job result. Planted core.fsmonitor is executed by both fetch calls; planted url.<base>.insteadOf + core.sshCommand rewrite the fetch onto an ssh transport that executes the payload with the PAT in its environment (survives actions/checkout, which rewrites remote.origin.url but not insteadOf); planted .git/info/grafts falsify rev-list/merge-base ancestry — GIT_NO_REPLACE_OBJECTS does not cover grafts — flipping a real single-parent push to skip=true; planted diff.context 0 removes context bytes from both digests, flipping the suite's own context_touch shape from skip=false to skip=true. All of these are also plantable through the runner user's global ~/.gitconfig, XDG git config, and .git/config.worktree.
Witness:
probes, unmodified gate in a scratch tree (this round):
uploadpack: --- payload executed: RAN GH_TOKEN=SECRET-TOKEN-VALUE (gate still certifies: skip=true)
fsmonitor: FSMON RAN 2 1787974766842462945 GH_TOKEN=SECRET-TOKEN-VALUE
insteadOf+ssh: SSH RAN GH_TOKEN=SECRET-TOKEN-VALUE
grafts: planted "<H> <R> <B>" — a real single-parent push flips to skip=true
(without the graft the walk rejects: non-merge commit)
diff.context 0: context_touch flips natural skip=false -> skip=true
mitigation: --upload-pack=git-upload-pack pinned on both fetches -> payload NOT executed, benign shape still skip=true
(-c remote.origin.uploadpack=… is NOT acceptable: measured to execute the planted value)
Fix: close the surface structurally rather than entrance by entrance — run every git call through a hardened wrapper following the repo's own norms (the workflow's GIT_SAFE idiom plus GIT_CONFIG_GLOBAL=/dev/null GIT_CONFIG_SYSTEM=/dev/null, or apply resanitize-git-config.sh as the other PAT-bearing paths do), compute the digest with plumbing immune to user diff config (git diff-tree -p --binary, or pin -U3 --ignore-submodules=none), fail open if $GIT_DIR/info/grafts exists, and pin the fetch transport at both call sites:
git fetch --no-tags --quiet --upload-pack=git-upload-pack origin "refs/pull/${PR_NUMBER}/head" || returnFix constraint: the retained fetches must keep --no-tags and the fail-open || return path — the script never exits non-zero (header contract, lines 43-46); git -c remote.origin.uploadpack=… is not an acceptable override (measured to execute the planted value; only the --upload-pack= flag form suppresses it).
Fix witness: extend plantAttackChannels() with one sentinel per channel (fsmonitor, pre-auto-gc + loose objects, insteadOf + sshCommand, grafts, diff.context 0, ignoreSubmodules, uploadpack) asserting no sentinel fires while update_branch_only still skips and the negative shapes keep their verdicts; removing any part of the hardening must turn the corresponding test red.

R5-1：[certifies-falsely] [new-surface] 本脚本对其 git 调用的加固是逐通道的——摘要调用上的 --no-ext-diff --no-textconv、全局 GIT_NO_REPLACE_OBJECTS=1——但它要关闭的表面是无界的：复用的自托管工作区中被植入（或合法存在）的 git 状态，正是文件头自己声明的威胁模型。本轮再次实证五个入口，全部在 fetch 时触发、位于台账查询之前、对每个匹配的自动 synchronize 生效、与标记状态无关——当前即为活通道。植入的 remote.origin.uploadpack 会把本行与 92 行的 git fetch 变成持 GH_TOKEN: secrets.CI_BOT_PAT 步骤里的任意代码执行——尽管有 GIT_NO_REPLACE_OBJECTS=1/--no-tags/--quiet，git 仍经 sh -c "<uploadpack> '<url>'" 运行植入程序，随后 fetch 失败、门向开放侧倒，入侵在作业结果中不可见。植入的 core.fsmonitor 由两次 fetch 执行；url.<base>.insteadOf + core.sshCommand 把 fetch 改写到 ssh 传输、在携带 PAT 的环境中执行载荷（actions/checkout 只改写 remote.origin.url、不清除 insteadOf）；植入的 .git/info/grafts 伪造 rev-list/merge-base 的祖先关系（GIT_NO_REPLACE_OBJECTS 不覆盖 grafts），把真实的单亲推送翻转为 skip=true；植入的 diff.context 0 从两侧摘要中移除上下文字节，把套件自己的 context_touch 形态从 skip=false 翻转为 skip=true。以上全部也可经 runner 用户的全局 ~/.gitconfig、XDG git 配置与 .git/config.worktree 植入。
证据：见英文部分（五通道探针全部触发；--upload-pack=git-upload-pack 可中和 uploadpack 通道且合法形态仍跳过；-c remote.origin.uploadpack=… 实测无效）。
修复：结构性关闭该表面而非逐入口封堵——让每个 git 调用走仓库自有规范的加固包装（workflow 的 GIT_SAFE 惯用法加 GIT_CONFIG_GLOBAL=/dev/null GIT_CONFIG_SYSTEM=/dev/null，或像其他持 PAT 路径那样应用 resanitize-git-config.sh），用免疫用户 diff 配置的管道命令计算摘要（git diff-tree -p --binary，或钉住 -U3 --ignore-submodules=none），若 $GIT_DIR/info/grafts 存在则向开放侧倒，并在两处 fetch 调用点钉住传输（见英文代码片段）。
修复约束：保留的 fetch 必须保持 --no-tags 与向开放侧倒的 || return 路径——脚本永不以非零退出（文件头契约，43-46 行）；git -c remote.origin.uploadpack=… 不是可接受的覆盖方式（实测会执行植入值，只有 --upload-pack= 标志形式可以中和）。
修复见证：在 plantAttackChannels() 中为每个通道加一个哨兵（fsmonitor、pre-auto-gc + 松散对象、insteadOf + sshCommand、grafts、diff.context 0、ignoreSubmodules、uploadpack），断言哨兵从不触发且 update_branch_only 仍跳过、各反例形态保持其裁决；移除任一加固，对应测试必须变红。

Deferred to the next round on round-budget grounds — not disagreement; the finding is verified real (same disposition as this finding's sibling threads). The live-today entrances reproduce; the structural fix (workspace-wide sanitization/hardened wrapper: config isolation, hooks/fsmonitor disabling, --upload-pack pinning, grafts fail-open, per-channel sentinels) is a dedicated work item exceeding this round's budget, which ships R5-3/R7-1/R3-3/R5-2 with red-before witnesses instead of a partial patch.

3 Suggestion-level finding(s) this review confirmed are already reported on this PR and are not repeated:
- the gate step's if-condition substring pinning — already reported (round-3 deferral list, review 5053525086, scripts/tests/qwen-pr-review-workflow.test.js:3940)
- the newest-marker-wins last selection unpinned — already reported (round-4 deferral list, review 5055802733, .github/scripts/review-base-refresh-gate.sh:119)
- R3-3 non-string marker base/sha aborts the jq program — already reported (open threads 3882692495/3884664482/3885155091, .github/scripts/review-base-refresh-gate.sh:118)
Not linted (tool limitation, not a blocker): the executable-script lint — .github/workflows/qwen-code-pr-review.yml: actionlint embedded-shell source mapping is not yet supported — not linted.
Deferred under the convergence posture (round 7, not a blocker) — recorded, not requested in this round; 1 Critical(s) among them are deferred by their axes — fails-closed on new surface, where no wrong result is certified and the merge base had neither the surface nor the defect — and remain follow-up work recorded in the findings artifact:
.github/scripts/review-base-refresh-gate.sh:125 — [review] Critical [fails-closed] [new-surface] R2-4: writer emits no base field — gate can never skip in productionscripts/tests/qwen-pr-review-workflow.test.js:4092 — [review] jq state filter admits APPROVED/CHANGES_REQUESTED but no fixture exercises either branch — mutant survives
Convergence: round 7 posted 4 inline comment(s), 1 of them reported for the first time; the previous round posted 4 (0 new). Findings keep coming back to the same files: .github/scripts/review-base-refresh-gate.sh (findings in rounds 4, 5; 1 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.)
Residual risk: this loop is persistently critical — Criticals stood in the previous round's work-list and stand again this round (4 Critical(s)), the rate of first-time findings is not falling (this round 1, previous 0), and the standing Critical backlog is not shrinking. The severity floor will not converge it. Recommendation: land-with-residual-risk — the exit is a maintainer risk-acceptance decision (merge, carrying the residual risk), not another review round. Residual-risk inventory for that decision (maintainer to complete):
| standing Critical | attack surface | attacker-dependency | blast radius |
|---|---|---|---|
| (each standing Critical) | … | … | … |
Advisory only — it does not block this review.

本轮确认的 3 条建议级发现已在 PR 上报告过，不再重复发布（列表见上方英文部分）。
未检查（工具限制，非阻断）：the executable-script lint — .github/workflows/qwen-code-pr-review.yml: actionlint embedded-shell source mapping is not yet supported — not linted。
收敛姿态下延后（第 7 轮，非阻断）——已记录，本轮不要求修改；其中 1 条 Critical 按其失败方向与对照基线延后——fails-closed 且 new-surface：未认证任何错误结果，且 merge base 既无该功能面也无该缺陷——作为后续工作记录在 findings 工件中：共 2 条（原文未翻译，列表见上方英文部分）。
收敛情况：第 7 轮发布了 4 条行内评论，其中 1 条是首次提出；上一轮发布了 4 条（其中 0 条首次提出）。发现反复回到同一批文件：.github/scripts/review-base-refresh-gate.sh（第 4、5 轮已出过发现，本轮又有 1 条）。一个不断再生兄弟发现的簇，通常意味着逐条修复只在处理同一根因的实例——先定位并处理该根因，或把独立的簇拆成单独的 PR，通常比逐条修复更快结束循环。（仅为观察——本轮评审未因此扣留任何内容。）
残余风险：本循环处于 persistently-critical 形态——上一轮工作清单中的 Critical 本轮依然存在（本轮 4 条 Critical），首次发现的速率没有下降（本轮 1，上一轮 0），且未决 Critical 积压没有减少。severity floor 无法使其收敛。建议：land-with-residual-risk——出口是 maintainer 的风险接受决定（合入并承担残余风险），而非再开一轮评审。供该决定使用的残余风险清单（maintainer 填写）：按每条未决 Critical 列出「攻击面 · 攻击者依赖性 · 影响范围」三栏。仅为建议——不阻断本次评审。

[Critical] R5-1: [certifies-falsely] [new-surface] The hardening this script applies to its git invocations is channel-by-channel — --no-ext-diff --no-textconv on the digest, GIT_NO_REPLACE_OBJECTS=1 globally — but the surface it closes is unbounded: git state planted (or legitimately present) in the reused self-hosted workspace, the exact threat model the header names. The entrances below were probe-verified again this round; they fire at fetch time, BEFORE the ledger lookup, on every matching automatic synchronize, regardless of marker state. A planted url.<base>.insteadOf + core.sshCommand rewrites this fetch (and its sibling at line 92) onto an ssh transport that executes the payload with the PAT in its environment; planted .git/info/grafts falsify rev-list/merge-base ancestry — GIT_NO_REPLACE_OBJECTS does not cover grafts — flipping a real single-parent push to skip=true; planted diff.context 0 removes context bytes from both digests, flipping the suite's own context_touch shape from skip=false to skip=true; planted remote.origin.uploadpack becomes arbitrary code execution once reached through a URL-rewrite channel. All of these are also plantable through the runner user's global ~/.gitconfig, XDG git config, and .git/config.worktree.
Witness:
probes, unmodified gate (this round):
insteadOf+ssh: payload ran (2 PIDs) with GH_TOKEN=SECRET-CI-BOT-PAT in env; gate emitted skip=true
grafts: planted "<H> <R> <B>" — a real single-parent push flips natural skip=false to skip=true
diff.context 0: context_touch flips natural skip=false -> skip=true
uploadpack: payload ran with PAT in env over file:// (against an https origin this entrance rides the proven insteadOf rewrite)
Fix: close the surface structurally rather than entrance by entrance — run every git call through a hardened wrapper following the repo's own norms (the workflow's GIT_SAFE idiom plus GIT_CONFIG_GLOBAL=/dev/null GIT_CONFIG_SYSTEM=/dev/null, or apply resanitize-git-config.sh as the other PAT-bearing paths do), compute the digest with plumbing immune to user diff config (git diff-tree -p --binary, or pin -U3 --ignore-submodules=none), fail open if $GIT_DIR/info/grafts exists, and pin the fetch transport at both call sites:
git fetch --no-tags --quiet --upload-pack=git-upload-pack origin "refs/pull/${PR_NUMBER}/head" || returnFix constraint: the retained fetches must keep --no-tags and the fail-open || return path — the script never exits non-zero (header contract, lines 43-46); git -c remote.origin.uploadpack=… is not an acceptable override (measured to execute the planted value; only the --upload-pack= flag form suppresses it).
Fix witness: extend plantAttackChannels() with one sentinel per channel (fsmonitor, insteadOf + sshCommand, grafts, diff.context 0, uploadpack) asserting no sentinel fires while update_branch_only still skips and the negative shapes keep their verdicts; removing any part of the hardening must turn the corresponding test red.

[Critical] R4-2: [certifies-falsely] [new-surface] The gate's base identity is the ref NAME only (the check at lines 125-128); a rewrite of the same-named base branch since the reviewed round slips through the certification and flips a review-deserving synchronize into skip=true. Both merge bases — this ancestry check and the mb_r/mb_h computations below — are recomputed against the rewritten live base, so digest equality holds by construction while the landed three-dot diff GAINS content the reviewed round never saw: round R reviews head against main tip C; a maintainer resets main backward (incident revert of a bad commit) and advances with different commits; the author hits update-branch — a plain two-parent merge whose second parent is an ancestor of the rewritten main; the walk passes and digest(mb(main_now, R)) == digest(mb(main_now, H)), so skip=true while the effective PR-side diff contains the dropped commit's content, riding back into main through this PR with no automatic round ever covering it. The retarget defence does not transfer: it catches a ref rename, not a same-name rewrite. Latent only until the marker writer emits base (the R2-4 gap), then live.
Witness:
probe, real git + stubbed gh (marker sha=R, base=main), this round:
[rewrite arm, ORIGINAL gate] skip=true — landed three-dot diff gains dropped-commit content
[normal arm] skip=true
[rewrite arm, FIX-MODEL gate] skip=false / reason=reviewed base commit … is not an ancestor of main
[normal arm, FIX-MODEL gate] skip=true
Fix: no gate-only fix exists — record the base COMMIT the round reviewed against (its merge-base) in the ledger marker alongside base (writer half, pairs with R2-4), and require here that it is still an ancestor of the live base tip, failing open otherwise; monotonic advance keeps skipping, any rewrite fails open:
git merge-base --is-ancestor "${REVIEWED_BASE_SHA}" "origin/${BASE_REF}" 2>/dev/null || returnFix constraint: the fix requires the writer-side change from R2-4 (the marker carries no base commit today); the new field rides inside LEDGER_MAX_BYTES = 8192 (packages/cli/src/commands/review/lib/ledger.ts:546) and must follow the anchor pair's withholding semantics (ledger.ts:657-666).
Fix witness: add an executed rebased_base shape — after the round reviews R, reset the origin base backward, add a commit, merge into the PR branch, assert skip=false; the current script returns skip=true for this shape, so the test is red today and pins the ancestor check once added (removing the check must turn it red again).
中文说明
R4-2：[certifies-falsely] [new-surface] 门对 base 的认证只认分支名字（125-128 行的检查）；已评审轮次之后同名 base 分支被重写，可以穿过认证、把本应评审的 synchronize 翻转为 skip=true。两个 merge-base——本行的祖先检查与下方的 mb_r/mb_h 计算——都相对重写后的活 base 重算，因此摘要等式按构造成立，而落地的三点 diff 却新增了已评审轮从未见过的内容：轮次 R 在 main 顶端 C 评审 head；维护者把 main 向后重置（事故回滚坏提交）并以不同提交继续；作者点 update-branch——普通双亲合并、第二亲本是重写后 main 的祖先；行走通过且两侧摘要相等——skip=true，而对活 base 的有效 PR 侧 diff 此时包含被丢弃提交的内容，借由本 PR 回到 main，没有任何自动轮覆盖过它。改道（retarget）防御无法迁移到本形态：它拦的是分支改名，不是同名重写。当前仅在标记写入端补齐 base（R2-4 缺口）之前处于潜在状态，之后即为活通道。
证据：见英文部分（重写分支 skip=true 且落地 diff 新增被丢弃提交内容；正常前进分支 skip=true；修复模型下重写分支翻转为 skip=false）。
修复：不存在仅门侧的修复——在台账标记中与 base 一并记录该轮评审所用的 base 提交（其 merge-base，写入端一半，与 R2-4 配对），并在门中要求它仍是活 base 顶端的祖先，否则向开放侧倒；单调前进照常跳过，任何重写都向开放侧倒（见英文代码片段）。
修复约束：该修复依赖 R2-4 的写入端改动（当前标记不携带 base 提交）；新字段位于 LEDGER_MAX_BYTES = 8192（packages/cli/src/commands/review/lib/ledger.ts:546）的字节预算内，并须遵循锚点对的扣留语义（ledger.ts:657-666）。
修复见证：新增执行形态 rebased_base——轮次评审 R 之后，把 origin base 向后重置、追加一个提交、合入 PR 分支，断言 skip=false；当前脚本对该形态返回 skip=true，因此该测试今天即为红，加入祖先检查后即被钉住（移除该检查必须再次变红）。

[Critical] R5-1: [certifies-falsely] [new-surface] The hardening this script applies to its git invocations is channel-by-channel — --no-ext-diff --no-textconv on the digest, GIT_NO_REPLACE_OBJECTS=1 globally — but the surface it closes is unbounded: git state planted (or legitimately present) in the reused self-hosted workspace, the exact threat model the header names. This round verified a further live entrance: the reference-transaction hook channel — this fallback fetch updates refs/remotes/origin/<base>, and a ref update executes a planted .git/hooks/reference-transaction (or core.hooksPath) hook in this PAT-bearing step. On a skip run the gate's git calls are the only code executing with CI_BOT_PAT.
Witness (probe at head 402bb22f, git 2.43, honest update-branch shape, fallback forced):
ARM A (.git/hooks/reference-transaction planted): HOOK-RAN: YES; gate skip=true
ARM B (core.hooksPath planted): HOOK-RAN: YES; gate skip=true
ARM C control (hook planted, origin/main present): HOOK-RAN: NO
Round-7 probes additionally demonstrated diff.external, textconv, and refs/replace entrances on the same script.
Fix direction: close the class structurally, not entrance by entrance — run the ref- and object-touching git invocations through the workflow's existing GIT_SAFE idiom (-c core.hooksPath=/dev/null -c core.fsmonitor=, qwen-code-pr-review.yml:546), keeping the fail-open contract (script header lines 42–46) — the flags must never turn a hook failure into a non-zero exit.
Please extend the suite's planted-channel cases with an executable reference-transaction hook (and a core.hooksPath variant) in a shape where the fallback fetch fires, asserting the hook never runs; removing the hardening must turn it red.

[Critical] R5-1：[certifies-falsely] [new-surface] 本脚本对其 git 调用的加固是逐通道的——摘要用 --no-ext-diff --no-textconv，全局设 GIT_NO_REPLACE_OBJECTS=1——但它要关闭的面是无界的：复用自托管工作区中被植入（或合法存在）的 git 状态，这正是文件头声明的威胁模型。本轮验证了又一个存活入口：reference-transaction 钩子通道——这个回退 fetch 会更新 refs/remotes/origin/<base>，而引用更新会在本持 PAT 的步骤里执行被植入的 .git/hooks/reference-transaction（或 core.hooksPath）钩子。跳过轮次中，门的 git 调用是唯一持 CI_BOT_PAT 执行的代码。
证据（在 head 402bb22f、git 2.43、真实 update-branch 形态且强制触发回退上探测）：ARM A（植入 .git/hooks/reference-transaction）：HOOK-RAN: YES，门 skip=true；ARM B（植入 core.hooksPath）：HOOK-RAN: YES，门 skip=true；ARM C 对照（植入钩子但 origin/main 存在）：HOOK-RAN: NO。第 7 轮的探针还曾在同一脚本上证明 diff.external、textconv 与 refs/replace 入口。
修复方向：结构性关闭该类，而非逐通道——让触及引用与对象的 git 调用走工作流既有的 GIT_SAFE 规范（-c core.hooksPath=/dev/null -c core.fsmonitor=，qwen-code-pr-review.yml:546），并保持 fail-open 契约（脚本头 42–46 行）——这些标志绝不能把钩子失败变成非零退出。
请在套件的植入通道用例中新增可执行的 reference-transaction 钩子（及 core.hooksPath 变体），构造触发回退 fetch 的形态，断言钩子从不执行；移除加固时该测试必须变红。

Deferred to the next round on round-budget grounds — not disagreement; the finding is verified real (same disposition as this finding's sibling threads).

[Critical] R4-2: [certifies-falsely] [new-surface] The gate's base identity is the ref NAME only (the check at lines 125–128); a rewrite of the same-named base branch since the reviewed round slips through the certification and flips a review-deserving synchronize into skip=true. Both merge bases — this ancestry check and the mb_r/mb_h computations below — are recomputed against the rewritten live base, so digest equality holds by construction while the landed three-dot diff GAINS content that was never reviewed. Re-verified at this head with an executed probe.
Witness (probe at head 402bb22f, rewritten-base fixture):
GITHUB_OUTPUT: skip=true reviewed_sha=<R> reason=
landing three-dot at H vs rewritten main: f.txt | 2 +- , other.txt | 1 + ← gains content
reviewed round's three-dot at review time: f.txt | 2 +- ← only this was reviewed
Fix direction: bind the certification to the base's identity, not its name — record the reviewed base tip beside sha/base in the ledger marker and require the current base tip to be a descendant of it (or equal), failing open on a rewritten base; the writer change must respect the marker's byte budget and shed cascade — LEDGER_MAX_BYTES = 8192 at packages/cli/src/commands/review/lib/ledger.ts:583 — and ride beside sha under the same withholding rule, never displacing it.
Please add a real-git fixture that rewrites the same-named base branch after the reviewed round and merges it, asserting skip=false; removing the base-identity binding must turn it red.

[Critical] R4-2：[certifies-falsely] [new-surface] 门的 base 身份只看引用名（125–128 行的检查）；自已评审轮次之后同名 base 分支被重写，可以滑过认证，把本应评审的 synchronize 翻转为 skip=true。两个 merge base——此处的祖先检查与下方的 mb_r/mb_h 计算——都按被重写的活 base 重新计算，因此摘要相等按构造成立，而落地的三点 diff 却新增了从未评审过的内容。本头已用执行探针重新验证。
证据（在 head 402bb22f 的重写 base 夹具上探测）：GITHUB_OUTPUT: skip=true reviewed_sha=<R> reason=；H 对重写后 main 的落地三点 diff：f.txt | 2 +- , other.txt | 1 +（新增内容）；评审时该轮的三点 diff 仅 f.txt | 2 +-（只评审了这些）。
修复方向：把认证绑定到 base 的身份而非名字——在台账标记中随 sha/base 记录已评审的 base 端点，并要求当前 base 端点是它的后代（或相等），base 被重写时向开放侧倒；写入端改动须遵守标记字节预算与丢弃级联——packages/cli/src/commands/review/lib/ledger.ts:583 的 LEDGER_MAX_BYTES = 8192——且与 sha 同乘同一扣留规则，绝不挤掉 sha。
请新增真实 git 夹具：在已评审轮次之后重写同名 base 分支并合入，断言 skip=false；移除 base 身份绑定时该测试必须变红。

Deferred to the follow-up queue — verified real, pairs with R2-4 (same disposition as this finding's sibling threads). The rewritten-base probe reproduces skip=true with gained landing content at this head. The base-identity binding must ride the ledger marker (writer change in packages/cli, outside this PR's footprint, respecting the marker's byte budget and shed cascade); it is recorded with R2-4's writer half and the gate-side check ships with it.

2 Suggestion-level finding(s) this review confirmed are already reported on this PR and are not repeated:
- the newest-marker-wins
lastselection is unpinned (a last->first mutation survives the suite) — already reported in the round-4 deferral list (review 5055802733, .github/scripts/review-base-refresh-gate.sh:119) - the fallback base-ref fetch cannot create refs/remotes/origin/ in a checkout-created workspace, so non-default-base PRs never skip — already reported in the round-3 deferral list (review 5053525086, .github/scripts/review-base-refresh…
Not linted (tool limitation, not a blocker): the executable-script lint — .github/workflows/qwen-code-pr-review.yml: actionlint embedded-shell source mapping is not yet supported — not linted.

.github/scripts/review-base-refresh-gate.sh:125 — [probe] Critical [fails-closed] [new-surface] R2-4: writer emits no base field — the gate can never skip in production; 'Closes #10111' would auto-close while the incident still reproducesscripts/tests/qwen-pr-review-workflow.test.js:4052 — [probe] gate-step ordering unpinned — moving base_refresh below the guarded steps silently disables the skip while all 205 tests stay green (mutant-verified).github/scripts/review-base-refresh-gate.sh:193 — [probe] note-posting failure path untested — an output-write reordering or propagated upsert failure ships green and spends the round the summary claimed to skip (mutant-verified)
Residual risk: this loop is persistently critical — Criticals stood in the previous round's work-list and stand again this round (4 Critical(s)), the rate of first-time findings is not falling (this round 0, previous 0), and the standing Critical backlog is not shrinking. The severity floor will not converge it. Recommendation: land-with-residual-risk — the exit is a maintainer risk-acceptance decision (merge, carrying the residual risk), not another review round. Residual-risk inventory for that decision (maintainer to complete):
| standing Critical | attack surface | attacker-dependency | blast radius |
|---|---|---|---|
| (each standing Critical) | … | … | … |
Advisory only — it does not block this review.

[Critical] R5-1: [certifies-falsely] [new-surface] The hardening this script applies to its git invocations is channel-by-channel — --no-ext-diff --no-textconv on the digest, GIT_NO_REPLACE_OBJECTS=1 globally — but the surface it closes is unbounded: git state planted (or legitimately present) in the reused self-hosted workspace, the exact threat model the header names. This round re-verified the reference-transaction hook entrance with an executed probe: the fallback fetch updates refs/remotes/origin/<base>, and a ref update executes a planted .git/hooks/reference-transaction (or core.hooksPath) hook in this PAT-bearing step. On a skip run the gate's git calls are the only code executing with CI_BOT_PAT. This round also observed (reasoned, not executed): a planted diff.context=0 makes both digest calls hash context-free diffs, so an evil base-merge resolution rewriting the context bytes adjacent to the PR's hunks would certify equal — another entrance to the same class.
Witness:
ARM A (.git/hooks/reference-transaction planted, origin/main deleted so the
fallback fires): 6 hook invocation(s), GH_TOKEN-VISIBLE-TO-HOOK yes
on every one, gate skip=true
ARM B (core.hooksPath planted): identical
ARM C control (hook planted, origin/main present, no fallback): HOOK-RAN: NO
Fix direction: close the class structurally, not entrance by entrance — run the ref- and object-touching git invocations through the workflow's existing GIT_SAFE idiom (-c core.hooksPath=/dev/null -c core.fsmonitor=, qwen-code-pr-review.yml:546), keeping the fail-open contract (script header lines 42–46) — the flags must never turn a hook failure into a non-zero exit.
Please extend the suite's planted-channel cases with an executable reference-transaction hook (and a core.hooksPath variant) in a shape where the fallback fetch fires, asserting the hook never runs; removing the hardening must turn it red.

[Critical] R5-1：[certifies-falsely] [new-surface] 本脚本对其 git 调用的加固是逐通道的——摘要用 --no-ext-diff --no-textconv，全局设 GIT_NO_REPLACE_OBJECTS=1——但它要关闭的面是无界的：复用自托管工作区中被植入（或合法存在）的 git 状态，这正是文件头声明的威胁模型。本轮已用执行探针重新验证 reference-transaction 钩子入口：这个回退 fetch 会更新 refs/remotes/origin/<base>，而引用更新会在本持 PAT 的步骤里执行被植入的 .git/hooks/reference-transaction（或 core.hooksPath）钩子。跳过轮次中，门的 git 调用是唯一持 CI_BOT_PAT 执行的代码。本轮另观察到（推理、未执行）：植入的 diff.context=0 会使两次摘要调用都哈希无上下文的 diff，因此恶意 base 合并重写 PR hunks 相邻的上下文字节也能认证相等——同一类的又一入口。
修复方向：结构性关闭该类，而非逐通道——让触及引用与对象的 git 调用走工作流既有的 GIT_SAFE 规范（-c core.hooksPath=/dev/null -c core.fsmonitor=，qwen-code-pr-review.yml:546），并保持 fail-open 契约（脚本头 42–46 行）——这些标志绝不能把钩子失败变成非零退出。请在套件的植入通道用例中新增可执行的 reference-transaction 钩子（及 core.hooksPath 变体），构造触发回退 fetch 的形态，断言钩子从不执行；移除加固时该测试必须变红。

Deferred to the next round on round-budget grounds — not disagreement; the finding is verified real (same disposition as this finding's sibling threads). The reference-transaction hook entrance is re-confirmed on the fallback fetch; the structural closure is a dedicated work item exceeding this round's budget, which ships R5-3/R7-1/R3-3/R5-2 with red-before witnesses instead of a partial per-channel patch.

[Critical] R5-1: [certifies-falsely] [new-surface] The hardening this script applies to its git invocations is channel-by-channel — --no-ext-diff --no-textconv on the digest, GIT_NO_REPLACE_OBJECTS=1 globally — but the surface it closes is unbounded: git state planted (or legitimately present) in the reused self-hosted workspace, the exact threat model the header names. Verified at this head: exactly three channels are hardened (line 50, lines 76-77), and the structural fix — workspace-wide git-state sanitization before the gate runs — is still absent (.github/scripts/resanitize-git-config.sh exists but qwen-code-pr-review.yml never references it). This round's audit demonstrated the class again: a planted/stale refs/remotes/origin/<base> short-circuits the base fetch at line 91, falsifies the walk and both merge-bases, and flips a payload-carrying head to skip=true — reproduced end-to-end with real git. Its current reachability was REFUTED this round (actions/checkout@v6's wildcard fetch always passes --prune before the gate, wiping the plant) — disclosed here, not claimed; the class finding stands on the unchanged structure, and it is the structure the next entrance of this kind will exploit.
Witness:
class state at HEAD: hardening = exactly three channels (line 50, lines 76-77); resanitize-git-config.sh present but unwired in this workflow
sibling probe (real git): planted refs/remotes/origin/main at fabricated payload tip P —
walk PASSES; merge-base(P,H)=P hides the payload from both digests; skip=true; MALICIOUS.txt at H (never reviewed)? YES
reachability arm: after checkout@v6's wildcard fetch with --prune the plant resets to the live tip —
gate: skip=false / reason=merge of a non-base branch
Close the surface structurally rather than entrance by entrance: wire resanitize-git-config.sh (or an equivalent workspace-wide git-state reset — config keys, refs, replace refs, hooks) into this workflow before the gate step runs.
Add a fixture planting git state the three channel flags do not cover (e.g. the stale origin/<base> ref above), run it through the sanitization step, and assert fail-open; removing the sanitization step must turn it red.

本脚本对自身 git 调用的加固是逐通道的——digest 用 --no-ext-diff --no-textconv、全局 GIT_NO_REPLACE_OBJECTS=1——但它封闭的面是无界的:复用的自托管工作区中被植入(或合法存在)的 git 状态,正是文件头自己声明的威胁模型。本 head 验证:恰有三个通道被加固(50 行、76-77 行),而结构性修复——门运行前对整个工作区做 git 状态净化——仍然缺失(.github/scripts/resanitize-git-config.sh 存在,但 qwen-code-pr-review.yml 从未引用它)。本轮审计再次演示了该类别:植入/过期的 refs/remotes/origin/<base> 会在 91 行让门跳过 base 拉取,伪造行走与两个 merge-base,把携带载荷的 head 翻转为 skip=true——已在真实 git 中端到端复现。其当前可达性在本轮被反驳(actions/checkout@v6 的通配拉取恒带 --prune,在门之前即清除植入)——此处如实披露、不作主张;类发现立足于未变的结构,下一同类入口利用的正是该结构。
修复方向:结构性封闭该面而非逐入口追赶——把 resanitize-git-config.sh(或等效的全工作区 git 状态重置——配置键、引用、replace 引用、钩子)接入本 workflow,在门步骤之前运行。
请新增一个植入三通道标志未覆盖之 git 状态(如上述过期 origin/<base> 引用)的夹具,经净化步骤运行后断言向开放侧倒;移除净化步骤时该测试必须变红。

[Critical] R4-2: [certifies-falsely] [new-surface] The gate's base identity is the ref NAME only (the check at lines 125-128); a rewrite of the same-named base branch since the reviewed round slips through the certification and flips a review-deserving synchronize into skip=true. Both merge bases are recomputed against the rewritten live base, so digest equality holds by construction while the landed three-dot diff GAINS content. The marker carries no base SHA/identity to compare — the writer emits no base field at all today. Still stands at this head.
Witness:
probe (real git, shipped script unmodified): main force-pushed to a divergent history after the reviewed round, PR merges the rewritten base —
gate output: skip=true
rewritten-by-force-push.txt at H? yes | at R? no
Certify base identity by commit, not name: when the writer half lands, record the base's merge-base SHA (or the base tip) beside sha in the ledger marker and compare it here; until then this check cannot distinguish a rewritten same-named base.
Add a real-git fixture replaying that force-push rewrite (marker recording the pre-rewrite base identity) asserting skip=false; removing the base-identity comparison must turn it red.

门的 base 身份只有引用名(125-128 行的检查);同名 base 分支自被评审轮之后被重写,即可穿过认证,把本应评审的 synchronize 翻转为 skip=true。两个 merge-base 都对着重写后的活 base 重算,因此 digest 相等按构造成立,而落地的三点 diff 实际新增了内容。标记中没有任何 base SHA/身份可供比较——写入方今天根本不输出 base 字段。本 head 仍然成立。
修复:以提交而非名字认证 base 身份——写入方一半落地时,在台账标记中与 sha 并列记录 base 的 merge-base SHA(或 base tip)并在此处比较;在此之前该检查无法区分被重写的同名 base。
请新增一个重演上述强推重写的真实 git 夹具(标记记录重写前的 base 身份),断言 skip=false;移除 base 身份比较时该测试必须变红。

Deferred to the follow-up queue — verified real, pairs with R2-4 (same disposition as this finding's sibling threads). The force-push rewrite probe reproduces skip=true at this head; the marker carries no base identity to compare because the writer emits no base field at all today. Certifying by base commit requires the writer half (outside this PR's footprint, packages/cli); recorded with R2-4.

Not linted (tool limitation, not a blocker): the executable-script lint — .github/workflows/qwen-code-pr-review.yml: actionlint embedded-shell source mapping is not yet supported — not linted.
Deferred under the convergence posture (round 11, not a blocker) — recorded, not requested in this round; 2 Critical(s) among them are deferred by their axes — fails-closed on new surface, where no wrong result is certified and the merge base had neither the surface nor the defect — and remain follow-up work recorded in the findings artifact:
.github/scripts/review-base-refresh-gate.sh:125 — [probe] Critical [fails-closed] [new-surface] R2-4: writer emits no base field — the gate can never skip in production; 'Closes #10111' would auto-close while the incident still reproducesscripts/tests/qwen-pr-review-workflow.test.js:4214 — [probe] Critical [fails-closed] [new-surface] R5-3: suite inherits ambient gitconfig; clone.defaultRemoteName hosts break 23 of 25 executed cases (CI lanes safe — fresh HOME).github/scripts/review-base-refresh-gate.sh:193 — [probe] note-posting failure path pinned by no behavioral test (|| exit 2 mutant survives).github/scripts/review-base-refresh-gate.sh:92 — [probe] git-side fail-open probes unexecuted; the base-ref fallback fetch mutant survives the suitescripts/tests/qwen-pr-review-workflow.test.js:4036 — [probe] gate-step test pins continue-on-error but not timeout-minutes: 5.github/scripts/review-base-refresh-gate.sh:117 — [probe] sixth unpinned copy of the ledger-marker grammar; SHA_RE drift survives the whole suite
Convergence: round 11 posted 5 inline comment(s), 1 of them reported for the first time; the previous round posted 4 (0 new). Findings keep coming back to the same files: .github/scripts/review-base-refresh-gate.sh (findings in rounds 4, 5, 7; 1 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.)
Residual risk: this loop is persistently critical — Criticals stood in the previous round's work-list and stand again this round (5 Critical(s)), the rate of first-time findings is not falling (this round 1, previous 0), and the standing Critical backlog is not shrinking. The severity floor will not converge it. Recommendation: land-with-residual-risk — the exit is a maintainer risk-acceptance decision (merge, carrying the residual risk), not another review round. Residual-risk inventory for that decision (maintainer to complete):
| standing Critical | attack surface | attacker-dependency | blast radius |
|---|---|---|---|
| (each standing Critical) | … | … | … |
Advisory only — it does not block this review.

残余风险：本循环处于 persistently-critical 形态——上一轮工作清单中的 Critical 本轮依然存在（本轮 5 条 Critical），首次发现的速率没有下降（本轮 1，上一轮 0），且未决 Critical 积压没有减少。severity floor 无法使其收敛。建议：land-with-residual-risk——出口是 maintainer 的风险接受决定（合入并承担残余风险），而非再开一轮评审。供该决定使用的残余风险清单（maintainer 填写）：按每条未决 Critical 列出「攻击面 · 攻击者依赖性 · 影响范围」三栏。仅为建议——不阻断本次评审。

[Critical] R5-1: [certifies-falsely] [new-surface] The hardening this script applies to its git invocations is channel-by-channel — --no-ext-diff --no-textconv on the digest, GIT_NO_REPLACE_OBJECTS=1 globally — but the surface it closes is unbounded: git state planted (or legitimately present) in the reused self-hosted workspace, the exact threat model the header names. Still stands at round 11: exactly three channels are hardened (line 50, lines 76-77), and the structural fix — workspace-wide git-state sanitization before the gate runs — is still absent (.github/scripts/resanitize-git-config.sh exists but this workflow never references it). This round's verification demonstrated the class again with a new entrance: a planted .git/info/grafts file — still honored by git 2.43 — re-parents the pushed head so the first-parent walk accepts a non-merge shape, and grafts also falsify git merge-base, which feeds both digests; the probe below flips a payload-carrying head to skip=true end-to-end while the gate runs with its own GIT_NO_REPLACE_OBJECTS=1. Reachability today requires a prior workspace compromise (the threat the header engages) and a base-carrying marker (armed the moment the writer follow-up lands).
Witness:
probe (round 11, real git 2.43, real gate script):
ARM no-grafts GITHUB_OUTPUT: skip=false / reason=non-merge commit since the reviewed head: <H>
ARM grafted GITHUB_OUTPUT: skip=true (note posted)
round-10 sibling entrance: planted refs/remotes/origin/main at fabricated payload tip P —
walk PASSES; merge-base(P,H)=P hides the payload from both digests; skip=true
Close the surface structurally rather than entrance by entrance: wire resanitize-git-config.sh (or an equivalent workspace-wide git-state reset — config keys, refs, replace refs, grafts, hooks) into this workflow before the gate step runs.
Add a fixture planting git state the three channel flags do not cover (e.g. the grafts file above), run it through the sanitization step, and assert fail-open; removing the sanitization step must turn it red.
中文说明
[Critical] R5-1:[certifies-falsely] [new-surface] 本脚本对自身 git 调用的加固是逐通道的——digest 用 --no-ext-diff --no-textconv、全局 GIT_NO_REPLACE_OBJECTS=1——但它封闭的面是无界的:复用的自托管工作区中被植入(或合法存在)的 git 状态,正是文件头自己声明的威胁模型。第 11 轮仍然成立:恰有三个通道被加固(50 行、76-77 行),结构性修复——门运行前对整个工作区做 git 状态净化——仍然缺失(.github/scripts/resanitize-git-config.sh 存在,但本 workflow 从未引用)。本轮验证再次以新入口演示了该类别:植入的 .git/info/grafts 文件(git 2.43 仍然接受)会重排推送 head 的父系,使 first-parent 行走接受非合并形态;grafts 还会伪造两个 digest 共同依赖的 git merge-base——下方探针在门自带 GIT_NO_REPLACE_OBJECTS=1 运行时,把携带载荷的 head 端到端翻转为 skip=true。当前可达性需要工作区先被植入(文件头声明的威胁)以及携带 base 的标记(写入方后续落地即被武装)。
证据(第 11 轮探针,真实 git 2.43、真实门脚本):无 grafts 臂 GITHUB_OUTPUT:skip=false / reason=non-merge commit since the reviewed head: ;植入 grafts 臂 GITHUB_OUTPUT:skip=true(说明已发)。第 10 轮兄弟入口:在伪造载荷 tip P 处植入 refs/remotes/origin/main——行走通过;merge-base(P,H)=P 让两个 digest 都看不见载荷;skip=true。
修复方向:结构性封闭该面而非逐入口追赶——把 resanitize-git-config.sh(或等效的全工作区 git 状态重置——配置键、引用、replace 引用、grafts、钩子)接入本 workflow,在门步骤之前运行。
请新增一个植入三通道标志未覆盖之 git 状态(如上述 grafts 文件)的夹具,经净化步骤运行后断言向开放侧倒;移除净化步骤时该测试必须变红。

Deferred to the next round on round-budget grounds — not disagreement; the finding is verified real (same disposition as this finding's sibling threads). The grafts entrance reproduces as described at round 11 (re-parented walk + falsified merge-base → skip=true, under the disclosed reachability conditions); the structural closure (workspace-wide git-state sanitization before the gate, including grafts/hooks/config/refs reset) is a dedicated work item exceeding this round's budget. This round ships R5-3/R7-1/R3-3/R5-2 with red-before witnesses.

[Critical] R4-2: [certifies-falsely] [new-surface] The gate's base identity is the ref NAME only (the check at lines 125-128); a rewrite of the same-named base branch since the reviewed round slips through the certification and flips a review-deserving synchronize into skip=true. Both merge bases are recomputed against the rewritten live base, so digest equality holds by construction while the landed three-dot diff GAINS content. The marker carries no base SHA/identity to compare — the writer emits no base field at all today. Still stands at round 11.
Witness:
probe (real git, shipped script unmodified): main force-pushed to a divergent history after the reviewed round, PR merges the rewritten base —
gate output: skip=true
rewritten-by-force-push.txt at H? yes | at R? no
Certify base identity by commit, not name: when the writer half lands, record the base's merge-base SHA (or the base tip) beside sha in the ledger marker and compare it here; until then this check cannot distinguish a rewritten same-named base.
Add a real-git fixture replaying that force-push rewrite (marker recording the pre-rewrite base identity) asserting skip=false; removing the base-identity comparison must turn it red.

[Critical] R11-1: [certifies-falsely] [new-surface] The base-refresh note this step posts goes out as qwen-code-ci-bot — the exact account qwen-autofix.yml defines as REVIEW_BOT (line 87) and deliberately counts as actionable feedback — but it lacks the exclusion every sibling non-actionable bot note carries in that workflow's activity filters: qwen-review-base-refresh appears in none of the eleven filter copies (BOT_COMMENT_FILTER ~line 3404, the docs-only exclusion ~3418, and the inline copies at ~4304/~4392/~4706/~4826/~4941), while autofix-eval, qwen-review-ack, pr-force-push and the rest are excluded. A fleet-engaged PR that receives the note is selected at the next scheduled scan and burns a full review-address agent round whose only output is a no-action report — the waste the filter comment says it exists to prevent — and autofix's own stale-base merges fire exactly this skip-and-note path, so the waste recurs per base refresh on every engaged PR. The note only posts when the gate skips, which today cannot happen (no writer emits base), so the defect ships armed and fires the moment the declared writer follow-up lands. Round-2 deferral lineage, confirmed Critical this round.
Witness:
probe (real jq over the filter block lifted verbatim from qwen-autofix.yml:3404-3420):
row 1: base-refresh note by REVIEW_BOT, filter as shipped: N_ISSUE_COMMENTS=1
row 2: sibling ack note (comparator sanity): N_ISSUE_COMMENTS=0
row 3: marker added to the alternation (fix arm): N_ISSUE_COMMENTS=0
Add qwen-review-base-refresh to the marker exclusions in qwen-autofix.yml at every site that admits REVIEW_BOT issue comments — BOT_COMMENT_FILTER (line 3404) and the inline docs-only-exclusion copies (~4304, ~4392, ~4706, ~4826, ~4941). The exclusion regex matches a trailing space after the marker name — BOT_COMMENT_FILTER='<!-- (autofix-eval|autofix-rearm|autofix-base-updated|autofix-milestone|qwen-triage|qwen-review-suggestion-summary|pr-force-push|qwen-review-ack) ' (qwen-autofix.yml:3404) — so the marker must join the alternation with that shape, or the note stays counted. Add a static assertion that every actionable-feedback filter excluding qwen-review docs-only-medium also excludes qwen-review-base-refresh; dropping the new marker from BOT_COMMENT_FILTER must turn it red.
中文说明
[Critical] R11-1:[certifies-falsely] [new-surface] 本步骤发布的 base 刷新说明以 qwen-code-ci-bot 发出——正是 qwen-autofix.yml 定义为 REVIEW_BOT(87 行)并刻意计为可执行反馈的账号——但它缺少该 workflow 活动过滤器中每条同类非执行机器人说明都携带的排除项:qwen-review-base-refresh 在全部十一处过滤器副本中均未出现(BOT_COMMENT_FILTER 约 3404 行、仅文档排除约 3418 行,以及约 4304/4392/4706/4826/4941 的内联副本),而 autofix-eval、qwen-review-ack、pr-force-push 等均已排除。被舰队(autofix)接管的 PR 收到该说明后,下一次定时扫描会选中它并消耗一整轮评审处理代理,其唯一产出是一份"无需操作"报告——正是过滤器注释说自己存在就是为了避免的浪费——且 autofix 自己的过期 base 合并恰好触发这条"跳过并发说明"的路径,因此每个被接管的 PR 上每次 base 刷新都会重复这一浪费。说明只在门跳过时发布,而今天门不可能跳过(没有写入方输出 base),所以该缺陷落地即处于武装状态,声明的写入方后续一落地即触发。第 2 轮延后谱系,本轮确认为 Critical。
证据(真实 jq,作用于自 qwen-autofix.yml:3404-3420 原样提取的过滤块):行 1:REVIEW_BOT 发布的 base 刷新说明,按落地过滤器:N_ISSUE_COMMENTS=1;行 2:兄弟 ack 说明(对照合理性):N_ISSUE_COMMENTS=0;行 3:把标记加入交替项(修复臂):N_ISSUE_COMMENTS=0。
修复:把 qwen-review-base-refresh 加入 qwen-autofix.yml 中所有接纳 REVIEW_BOT issue 评论位置的排除项——BOT_COMMENT_FILTER(3404 行)与内联的仅文档排除副本(约 4304、4392、4706、4826、4941)。约束:排除正则要求标记名后带尾随空格——BOT_COMMENT_FILTER='<!-- (…) '(qwen-autofix.yml:3404);加入交替项时必须保持该形态,否则说明仍被计数。
请新增静态断言:每个排除 qwen-review docs-only-medium 的可执行反馈过滤器也必须排除 qwen-review-base-refresh;从 BOT_COMMENT_FILTER 移除新标记时该测试必须变红。

Deferred to the follow-up queue — verified real. qwen-review-base-refresh appears in none of qwen-autofix.yml's actionable-feedback filters at this head (checked BOT_COMMENT_FILTER at line 3404 and the inline copies), so an engaged PR receiving the note spends a full no-action round per base refresh once the gate can skip. The fix (add the marker to every filter copy admitting REVIEW_BOT issue comments, plus a static assertion pairing it with the docs-only exclusion) lives in qwen-autofix.yml — the autofix loop's own workflow, outside this PR's footprint and a protected area — so it is recorded for the follow-up queue rather than implemented here.
中文说明
延后至后续队列——已核实为真。本 head 上 qwen-review-base-refresh 未出现在 qwen-autofix.yml 的任何可执行反馈过滤器中（已检查第 3404 行的 BOT_COMMENT_FILTER 与各内联副本），因此一旦门可以跳过，收到该说明的被接管 PR 会在每次 base 刷新时消耗一整轮"无需操作"的轮次。修复（把该标记加入所有接纳 REVIEW_BOT issue 评论的过滤器副本，并新增与仅文档排除配对的静态断言）位于 qwen-autofix.yml——autofix 循环自己的 workflow，在本 PR 足迹之外且属受保护区域——故记录到后续队列，不在此实现。
Address review findings on the base-refresh gate: - require each walk commit's tree to equal its parents' clean merge (git merge-tree --write-tree), closing commit-tree-crafted merges that relocate the reviewed hunks past the offset-stripped digest (R5-2) - let the newest ledger-marked bot review decide: a withheld or malformed sha anchor fails open instead of falling through to an older marker, and non-string sha/base fields are coerced so they drop out instead of aborting every later lookup (R7-1, R3-3) - isolate the gate fixture's child processes from ambient gitconfig and pin the fixture remote name, so hosts with a hostile clone.defaultRemoteName run the suite green (R5-3)

[Critical] R4-2: [certifies-falsely] [new-surface] The gate's base identity is the ref NAME only (the check at lines 132-135); a rewrite of the same-named base branch since the reviewed round slips through the certification and flips a review-deserving synchronize into skip=true. Both merge bases — this computation and the one below it — are recomputed against the rewritten live base, so digest equality holds by construction while the landed three-dot diff GAINS content the reviewed round never saw: round R reviews head against main tip C; a maintainer resets main backward (incident revert of a bad commit) and advances with different commits; the author hits update-branch — a plain two-parent merge whose second parent is an ancestor of the rewritten main; the walk passes and digest(mb(main_now, R)) == digest(mb(main_now, H)), so skip=true while the effective PR-side diff contains the dropped commit's content, riding back into main through this PR with no automatic round ever covering it. The retarget defence does not transfer: it catches a ref rename, not a same-name rewrite. The hole arms the moment the marker writer emits base (R2-4) — which is exactly the state the gate requires to ever skip at all.
Witness:
probe, real git + stubbed gh (marker carrying sha=R and base=main), unmodified gate:
[rewrite] skip=true, reviewed_sha=ec56808… — landed three-dot diff gains the
dropped commit's content (f.txt modified, x.txt added)
[normal] monotonic advance still skips
Fix: no gate-only fix exists — record the base COMMIT the round reviewed against (its merge-base) in the ledger marker alongside base (writer half, pairs with R2-4, outside this PR's footprint in packages/cli), and require here that it is still an ancestor of the live base tip, failing open otherwise: git merge-base --is-ancestor "${REVIEWED_BASE_SHA}" "origin/${BASE_REF}" 2>/dev/null || return. The new field rides inside LEDGER_MAX_BYTES = 8192 (packages/cli/src/commands/review/lib/ledger.ts:583) and must follow the anchor pair's withholding semantics (ledger.ts:145-150). Add an executed rebased_base shape — after the round reviews R, reset the origin base backward, add a commit, merge into the PR branch, assert skip=false; the current script returns skip=true for this shape, so the test is red today and pins the ancestor check once added (removing the check must turn it red again).

Stays deferred to the follow-up queue (first recorded in round 12). The finding is verified real — a same-name base rewrite does slip through the ref-name-only certification while digest equality holds by construction — but its fix straddles this PR's footprint: recording the reviewed base COMMIT in the ledger marker is writer-side work in packages/cli (paired with the deferred R2-4 writer field), and this PR touches only the gate script, the review workflow, and its test suite. As the finding itself notes, no gate-only fix exists, so the writer field and the gate-side ancestor check (with the executed rebased_base fixture) must land together in the follow-up rather than shipping a gate check keyed on a field no writer emits. The hole stays unarmed until then: no marker carries base today, so the gate cannot skip in production at all.
中文说明
继续保持延后处理，已记录至后续队列（第 12 轮首次记录）。该发现已核实为真——同名 base 分支被重写确实能穿过仅认分支名的认证，且摘要等式按构造成立——但其修复跨越本 PR 的足迹：在台账标记中记录该轮评审所对的 base 提交是 packages/cli 中的写入端工作（与已延后的 R2-4 写入端字段配对），而本 PR 只触及门脚本、评审工作流及其测试套件。正如该发现自身所述，不存在仅门侧的修复，因此写入端字段与门侧祖先检查（连同执行夹具 rebased_base）必须在后续工作中一并落地，而不是先交付一个依赖尚无任何写入端输出的字段的门侧检查。在此之前该漏洞未装弹：今天没有任何标记携带 base，门在生产中根本无法跳过。

[Critical] R11-1: [certifies-falsely] [new-surface] The base-refresh note this step posts goes out as qwen-code-ci-bot — the exact account qwen-autofix.yml defines as REVIEW_BOT (line 87) and deliberately counts as actionable feedback — but it lacks the exclusion every sibling non-actionable bot note carries: qwen-review-base-refresh appears in none of the twelve actionable-feedback filter copies in qwen-autofix.yml at this head, while autofix-eval, qwen-review-ack, pr-force-push and the rest are excluded. A fleet-engaged PR that receives the note is selected at the next scheduled scan and burns a full review-address agent round whose only output is a no-action report — and autofix's own stale-base merges fire exactly this skip-and-note path, so the waste recurs on engaged PRs. Measured refinement: once per posted note, not per refresh — the upsert PATCHes the same comment in place and the autofix watermark advances past its created_at; deleting the note re-arms it. The note only posts when the gate skips, which today cannot happen (no writer emits base), so the defect ships armed and fires the moment the declared writer follow-up lands.
Witness:
sweep: grep qwen-review-base-refresh over .github/workflows/qwen-autofix.yml at HEAD -> 0 matches

Fix: add qwen-review-base-refresh to the marker exclusions in qwen-autofix.yml at every site that admits REVIEW_BOT issue comments — the exclusion regex matches a trailing space after the marker name, so the marker must join the alternation with that shape. Add a static assertion that every actionable-feedback filter excluding qwen-review docs-only-medium also excludes qwen-review-base-refresh; dropping the new marker from BOT_COMMENT_FILTER must turn it red.

Stays deferred to the follow-up queue (first recorded in round 12). Verified again at this head: qwen-review-base-refresh occurs 0 times in .github/workflows/qwen-autofix.yml, while the note this gate posts is authored by the REVIEW_BOT account and would count as actionable feedback. The fix — adding the marker to the exclusion alternation at every REVIEW_BOT-admitting filter site, plus the static assertion pairing it with the qwen-review docs-only-medium exclusion — lives entirely in qwen-autofix.yml: outside this PR's diff, and inside the autofix loop's own workflow area, which this PR's review rounds must not modify. It remains recorded for the follow-up queue. The waste stays latent until the writer follow-up lands: no writer emits base today, so the gate cannot skip and the note cannot post in production.

- 'empty PR-side diff' fail-open branch exercised by no fixture — already reported (round-3 deferral lineage, review 5053525086, .github/scripts/review-base-refresh-gate.sh:177)
Not linted (tool limitation, not a blocker): the executable-script lint — .github/workflows/qwen-code-pr-review.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; 1 Critical(s) among them are deferred by their axes — fails-closed on new surface, where no wrong result is certified and the merge base had neither the surface nor the defect — and remain follow-up work recorded in the findings artifact:
.github/scripts/review-base-refresh-gate.sh:132 — [review] Critical [fails-closed] [new-surface] R2-4: writer emits no base field — the gate can never skip in production; 'Closes #10111' would auto-close while the incident still reproduces.github/scripts/review-base-refresh-gate.sh:207 — [probe] note posts with no live PR-state recheck before the mutation; a merge/close landing during the step budget posts the note onto a closed/merged PR with a dead CTA
Convergence: round 13 posted 4 inline comment(s), 1 of them reported for the first time; the previous round posted 3 (0 new). Findings keep coming back to the same files: .github/scripts/review-base-refresh-gate.sh (findings in rounds 4, 5, 11; 1 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.)
Residual risk: this loop is persistently critical — Criticals stood in the previous round's work-list and stand again this round (4 Critical(s)), the rate of first-time findings is not falling (this round 1, previous 0), and the standing Critical backlog is not shrinking. The severity floor will not converge it. Recommendation: land-with-residual-risk — the exit is a maintainer risk-acceptance decision (merge, carrying the residual risk), not another review round. Residual-risk inventory for that decision (maintainer to complete):
| standing Critical | attack surface | attacker-dependency | blast radius |
|---|---|---|---|
| (each standing Critical) | … | … | … |
Advisory only — it does not block this review.

本轮确认的 6 条建议级发现已在 PR 上报告过，不再重复发布（列表见上方英文部分）。
未检查（工具限制，非阻断）：the executable-script lint — .github/workflows/qwen-code-pr-review.yml: actionlint embedded-shell source mapping is not yet supported — not linted。
收敛姿态下延后（第 13 轮，非阻断）——已记录，本轮不要求修改；其中 1 条 Critical 按其失败方向与对照基线延后——fails-closed 且 new-surface：未认证任何错误结果，且 merge base 既无该功能面也无该缺陷——作为后续工作记录在 findings 工件中：共 2 条（原文未翻译，列表见上方英文部分）。
收敛情况：第 13 轮发布了 4 条行内评论，其中 1 条是首次提出；上一轮发布了 3 条（其中 0 条首次提出）。发现反复回到同一批文件：.github/scripts/review-base-refresh-gate.sh（第 4、5、11 轮已出过发现，本轮又有 1 条）。一个不断再生兄弟发现的簇，通常意味着逐条修复只在处理同一根因的实例——先定位并处理该根因，或把独立的簇拆成单独的 PR，通常比逐条修复更快结束循环。（仅为观察——本轮评审未因此扣留任何内容。）
残余风险：本循环处于 persistently-critical 形态——上一轮工作清单中的 Critical 本轮依然存在（本轮 4 条 Critical），首次发现的速率没有下降（本轮 1，上一轮 0），且未决 Critical 积压没有减少。severity floor 无法使其收敛。建议：land-with-residual-risk——出口是 maintainer 的风险接受决定（合入并承担残余风险），而非再开一轮评审。供该决定使用的残余风险清单（maintainer 填写）：按每条未决 Critical 列出「攻击面 · 攻击者依赖性 · 影响范围」三栏。仅为建议——不阻断本次评审。

[Critical] R4-2: [certifies-falsely] [new-surface] The gate's base identity is the ref NAME only (the check at lines 132-135); a rewrite of the same-named base branch since the reviewed round slips through the certification and flips a review-deserving synchronize into skip=true. Still stands at this head: both merge bases — this computation and the one below it — are recomputed against the rewritten live base, so digest equality holds by construction while the landed three-dot diff GAINS content the reviewed round never saw. Round R reviews head against main tip C; a maintainer resets main backward (incident revert of a bad commit) and advances with different commits; the author hits update-branch — a plain two-parent merge whose second parent is an ancestor of the rewritten main; the walk passes and digest(mb(main_now, R)) == digest(mb(main_now, H)), so skip=true while the effective PR-side diff contains the dropped commit's content, riding back into main through this PR with no automatic round ever covering it. The retarget defence does not transfer: it catches a ref rename, not a same-name rewrite. The hole arms the moment the marker writer emits base (R2-4) — exactly the state the gate requires to ever skip at all. No fix has landed since round 12: the check at lines 132-135 is unchanged and the writer-side base-commit field still does not exist.
Fix: no gate-only fix exists — record the base COMMIT the round reviewed against (its merge-base) in the ledger marker alongside base (writer half, pairs with R2-4, outside this PR's footprint in packages/cli), and require here that it is still an ancestor of the live base tip, failing open otherwise: git merge-base --is-ancestor "${REVIEWED_BASE_SHA}" "origin/${BASE_REF}" 2>/dev/null || return.
Witness:
round-12 probe (carried), real git + stubbed gh, marker carrying sha=R and base=main, unmodified gate:
[rewrite] skip=true, reviewed_sha=ec56808… — landed three-dot diff gains the
dropped commit's content (f.txt modified, x.txt added)
[normal] monotonic advance still skips
this round: the check at lines 132-135 remains ref-name-only at this head (committed script read).
The new marker field rides inside LEDGER_MAX_BYTES = 8192 (packages/cli/src/commands/review/lib/ledger.ts:583) and must follow the anchor pair's withholding semantics (ledger.ts:145-150) — withheld whenever sha is withheld. Please add an executed rebased_base fixture: after the round reviews R, reset the origin base backward, add a commit, merge into the PR branch, assert skip=false — the current script returns skip=true for this shape, so the test is red today and pins the ancestor check once added; removing the check must turn it red again.

修复：不存在仅门侧的修复——在台账标记中于 base 旁记录该轮评审所对的 base 提交（其 merge-base；写入端一半，与 R2-4 配对，位于本 PR 足迹之外的 packages/cli），并在此要求其仍为活 base 顶端的祖先，否则向开放侧倒：git merge-base --is-ancestor "${REVIEWED_BASE_SHA}" "origin/${BASE_REF}" 2>/dev/null || return。
证据：第 12 轮探针（沿用），真实 git + 打桩 gh、标记携带 sha=R 与 base=main、未修改的门：[重写] skip=true、reviewed_sha=ec56808…——落地三点 diff 新增被丢弃提交的内容（f.txt 被修改、x.txt 被新增）；[正常] 单调前进仍然跳过。本轮：132-135 行的检查在该 head 上仍为仅认分支名（已读提交脚本）。
修复约束：新标记字段位于 LEDGER_MAX_BYTES = 8192（packages/cli/src/commands/review/lib/ledger.ts:583）之内，并须遵循锚点对的扣留语义（ledger.ts:145-150）——凡扣留 sha 的形态一律扣留该字段。请新增执行夹具 rebased_base：轮次评审 R 之后，把 origin base 向后重置、追加一个提交、合入 PR 分支，断言 skip=false——当前脚本对该形态返回 skip=true，测试今天即为红色，加入祖先检查后钉住它；移除该检查必须再次变红。

Stays deferred to the follow-up queue (first recorded in round 12). Same disposition as the round-12 thread: verified real, but the fix requires the writer-side base-commit field in packages/cli (outside this PR's footprint, paired with the deferred R2-4) plus the gate-side ancestor check landing together; no gate-only fix exists, per the finding itself. Until the writer ships, no marker carries base, the gate never skips in production, and this shape stays unarmed. The gate script changes this round (planted-config class closure, marker fall-through fix) do not interact with this hole.

Still stands: round 12 deferred the fix to the follow-up queue (it lives in qwen-autofix.yml, outside this PR's diff) and it has not landed. A fleet-engaged PR that receives the note is selected at the next scheduled autofix scan and burns a full review-address agent round whose only output is a no-action report — and autofix's own stale-base merges fire exactly this skip-and-note path, so the waste recurs on engaged PRs.

Stays deferred to the follow-up queue (first recorded in round 12). Disposition unchanged from the round-12 thread: the defect is verified (zero occurrences of the marker in qwen-autofix.yml at this head, re-grepped), but the entire fix is an edit to .github/workflows/qwen-autofix.yml — outside this PR's footprint and inside the autofix loop's own workflow area, which review rounds on this PR are not permitted to modify. The follow-up queue entry carries the fix shape: add qwen-review-base-refresh (trailing space, matching the exclusion regex) to every actionable-feedback filter admitting REVIEW_BOT issue comments, and add the static assertion so dropping the marker from BOT_COMMENT_FILTER turns the suite red.

继续保持延后处理，已记录至后续队列（第 12 轮首次记录）。处置与第 12 轮线程相同：缺陷已核实（本 head 上该标记在 qwen-autofix.yml 中出现零次，已重新扫描确认），但整个修复都是对 .github/workflows/qwen-autofix.yml 的编辑——位于本 PR 足迹之外，且属于 autofix 循环自身的工作流区域，本 PR 的评审轮次不得修改。后续队列条目已记录修复形态：在每处接纳 REVIEW_BOT issue 评论的可执行反馈过滤器中加入 qwen-review-base-refresh （带尾随空格，与排除正则形态一致），并新增静态断言，使从 BOT_COMMENT_FILTER 中去掉该标记时测试套件变红。

[Critical] R4-2: [certifies-falsely] [new-surface] The gate's base identity is the ref NAME only (the check below); a rewrite of the same-named base branch since the reviewed round slips through the certification and flips a review-deserving synchronize into skip=true. Still stands at this head: both merge bases are recomputed against the rewritten live base, so digest equality holds by construction while the landed three-dot diff GAINS content the reviewed round never saw. Concretely: round R reviews a head against main tip C; a maintainer resets main backward (incident revert of a bad commit) and advances with different commits; the author hits update-branch — a plain two-parent merge whose second parent is an ancestor of the rewritten main; the walk passes and the digests match, so skip=true while the effective PR-side diff contains the dropped commit's content, riding back into main through this PR with no automatic round ever covering it. The retarget defence does not transfer: it catches a ref rename, not a same-name rewrite. No gate-only fix exists: record the base COMMIT the round reviewed against (its merge-base) in the ledger marker alongside base (writer half, pairs with R2-4, in packages/cli), and require here that it is still an ancestor of the live base tip, failing open otherwise. The new marker field rides inside LEDGER_MAX_BYTES = 8192 (packages/cli/src/commands/review/lib/ledger.ts:583) and must follow the anchor pair's withholding semantics (ledger.ts:145-150) — withheld whenever sha is withheld. Please add an executed rebased_base fixture: after the round reviews R, reset the origin base backward, add a commit, merge into the PR branch, assert skip=false — the current script returns skip=true for this shape, so the test is red today and pins the ancestor check once added; removing the check must turn it red again.
Witness:
probe at head (real git + stubbed gh, marker sha=R base=main, unmodified gate):
[rewrite] GITHUB_OUTPUT: skip=true, reviewed_sha=fc66255... C1 reachable from main? NO
landed three-dot diff gains the dropped commit's content
(dropped.txt added, f.txt modified) the reviewed round never saw
[normal] monotonic advance still skips

[Critical] R4-2：[certifies-falsely] [new-surface] 门对 base 的认证只认分支名字（下方检查）；已评审轮次之后同名 base 分支被重写，可以穿过认证、把本应评审的 synchronize 翻转为 skip=true。该 head 上仍然成立：两个 merge-base 都相对重写后的活 base 重算，因此摘要等式按构造成立，而落地的三点 diff 却新增了已评审轮从未见过的内容。具体：轮次 R 在 main 顶端 C 评审 head；维护者把 main 向后重置（事故回滚坏提交）并以不同提交继续；作者点 update-branch——普通双亲合并、第二亲本是重写后 main 的祖先；行走通过且摘要相等，于是 skip=true，而有效 PR 侧 diff 此时包含被丢弃提交的内容，借由本 PR 回到 main，没有任何自动轮覆盖过它。改道（retarget）防御无法迁移到本形态：它拦的是分支改名，不是同名重写。不存在仅门侧的修复：在台账标记中于 base 旁记录该轮评审所对的 base 提交（其 merge-base；写入端一半，与 R2-4 配对，位于 packages/cli），并在此要求其仍为活 base 顶端的祖先，否则向开放侧倒。新标记字段位于 LEDGER_MAX_BYTES = 8192（packages/cli/src/commands/review/lib/ledger.ts:583）之内，并须遵循锚点对的扣留语义（ledger.ts:145-150）——凡扣留 sha 的形态一律扣留该字段。请新增执行夹具 rebased_base：轮次评审 R 之后，把 origin base 向后重置、追加一个提交、合入 PR 分支，断言 skip=false——当前脚本对该形态返回 skip=true，测试今天即为红色，加入祖先检查后钉住它；移除该检查必须再次变红。

Stays deferred to the follow-up queue (first recorded in round 12). Re-verified at this head: the certification still keys on the ref name only, and the writer-side base-commit field still does not exist. The disposition is unchanged for the reason in the finding itself — no gate-only fix exists. The gate-side ancestor check (git merge-base --is-ancestor "$REVIEWED_BASE_SHA" "origin/$BASE_REF") only has meaning once the ledger writer emits the base commit, and that writer half lives in packages/cli, outside this PR's footprint and paired with the deferred R2-4. Shipping the gate half alone would add dead code keyed on an unpinned future field; the follow-up lands both halves plus the executed rebased_base fixture together. The hole is latent until then (no marker carries base, the gate never skips in production).
中文说明
继续保持延后处理，已记录至后续队列（第 12 轮首次记录）。已在本 head 上重新核实：认证仍仅以分支名为键，写入端 base 提交字段仍不存在。处置不变，原因即该发现自身所述——不存在仅门侧的修复。门侧祖先检查（git merge-base --is-ancestor "$REVIEWED_BASE_SHA" "origin/$BASE_REF"）只有在台账写入端输出 base 提交后才有意义，而写入端位于本 PR 足迹之外的 packages/cli，并与已延后的 R2-4 配对。仅交付门侧一半会引入依赖未钉住的未来字段的死代码；后续工作将把两侧与执行夹具 rebased_base 一并落地。在此之前该漏洞处于潜伏状态（没有标记携带 base，门在生产中从不跳过）。

[Critical] R11-1: [certifies-falsely] [new-surface] The base-refresh note this step posts goes out as qwen-code-ci-bot — the exact account qwen-autofix.yml defines as REVIEW_BOT (line 87) and deliberately counts as actionable feedback — but it lacks the exclusion every sibling non-actionable bot note carries: qwen-review-base-refresh appears in none of qwen-autofix.yml's actionable-feedback filters (BOT_COMMENT_FILTER line 3404 and the inline copies), while autofix-eval, qwen-review-ack, pr-force-push and the rest are excluded. Still stands at this head: qwen-review-base-refresh occurs zero times in qwen-autofix.yml. A fleet-engaged PR that receives the note is selected at the next scheduled scan — the actionable-comment count admits the bot's note (user.login == REVIEW_BOT and the marker is not filtered) — and burns a full review-address agent round whose only output is a no-action report, the waste the filter comment says it exists to prevent. Because the note is upserted in place, the burn is per engagement window (first base-refresh note per PR). Add qwen-review-base-refresh to the marker exclusions in qwen-autofix.yml at every site that admits REVIEW_BOT issue comments — BOT_COMMENT_FILTER (line 3404) and the inline docs-only-exclusion copies. The exclusion regex matches a trailing space after the marker name (BOT_COMMENT_FILTER='<!-- (autofix-eval|...|qwen-review-ack) ', qwen-autofix.yml:3404), so the marker must join the alternation with that shape, or the note stays counted. Please add a static assertion that every actionable-feedback filter excluding qwen-review docs-only-medium also excludes qwen-review-base-refresh; dropping the new marker from BOT_COMMENT_FILTER must turn it red.
Witness:
probe (real jq over the filter block lifted verbatim from qwen-autofix.yml:3404-3420):
D1: N_ISSUE_COMMENTS = 1 the gate's exact base-refresh note body, filter as shipped
D2: N_ISSUE_COMMENTS = 0 same body carrying the sibling qwen-review-ack marker

Stays deferred to the follow-up queue (first recorded in round 12). Verified at this head as in rounds 12–13: the marker appears 0 times in qwen-autofix.yml. This round's gate-script changes (planted-config class closure, -U3 digest pin, marker fall-through fix) do not touch the note path's filter interaction, so the disposition is unchanged: the fix is a qwen-autofix.yml-only edit — outside this PR's footprint and inside the autofix loop's own workflow area, off-limits to this PR's review rounds — and it stays recorded for the follow-up queue with its acceptance criterion (the static assertion pairing the new marker with the docs-only exclusion). Latent until the writer follow-up lands: with no writer emitting base, the gate cannot skip and the note cannot post in production.

Partially reviewed — gaps disclosed.
4 Suggestion-level finding(s) this review confirmed are already reported on this PR and are not repeated:
- gate-step ordering unpinned (moving the gate below the guarded steps keeps every test green) — already reported (round-9 deferral list, review 5057940872, scripts/tests/qwen-pr-review-workflow.test.js:4052)
- note-posting failure path pinned by no behavioral test (the || exit 2 mutant survives the shipped suite) — already reported (round-9 and round-11 deferral lists, reviews 5057940872 / 5058759423, .github/scripts/review-base-refresh-gate.sh:1…
- diff_digest buffers the whole --binary diff in a shell variable (~1.01 GB RSS measured on an 80 MiB asset) — already reported (round-10 deferral list, review 5057455420, .github/scripts/review-base-refresh-gate.sh:77)
- note posts with no live PR-state recheck before the mutation (a merge/close during the delay window still gets the note) — already reported (round-13 deferral list, review 5059533052, .github/scripts/review-base-refresh-gate.sh:207)
Not reviewed: the executable-script lint — .github/scripts/review-base-refresh-gate.sh: shellcheck is not installed.
Not explored to full depth (tool budget reached): "agent 6b": none — no check was cut short.; "agent 1d": none — the checklist walk completed within budget; nothing was cut short..
Not linted (tool limitation, not a blocker): the executable-script lint — .github/workflows/qwen-code-pr-review.yml: actionlint embedded-shell source mapping is not yet supported — not linted.
Deferred under the convergence posture (round 15, not a blocker) — recorded, not requested in this round; 1 Critical(s) among them are deferred by their axes — fails-closed on new surface, where no wrong result is certified and the merge base had neither the surface nor the defect — and remain follow-up work recorded in the findings artifact:
.github/scripts/review-base-refresh-gate.sh:184 — [review] Critical [fails-closed] [new-surface] R2-4: writer emits no base field — the gate can never skip in production; 'Closes #10111' would auto-close while the incident still reproduces.github/scripts/review-base-refresh-gate.sh:116 — [review] fail-open REASON 'planted git attributes present' is assigned before rev-parse --git-dir and misnames a non-git workspace.github/scripts/review-base-refresh-gate.sh:264 — [review] the mktemp'd note body file has no sweep; cancel-in-progress leaks one file per killed skip run on the shared pool.github/scripts/review-base-refresh-gate.sh:134 — [review] the PR-head network fetch runs before the cheap marker lookup; every fail-open run pays the transfer first
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] R5-1: [certifies-falsely] [new-surface] This commit's header claims "the whole planted-config class is closed, not entrance by entrance", but the closure is a denylist over git config --local keys only, and it still leaves live entrances against the reused self-hosted workspace — the exact threat model the header names — verified at this head by executing the committed script. A planted remote.origin.uploadpack (no scrub-regex match) executes on the gate's own unconditional git fetch before any marker lookup: arbitrary code execution in this PAT-bearing step, on every gate run, regardless of marker state. Keys planted only in .git/config.worktree are invisible to the --local enumeration, so the scrub "succeeds" while merge-tree executes a planted merge driver and the gate emits skip=true over the payload run. The same bypass reopens through include.path, which actions/checkout never unsets and the scrub never walks — payload files outside the worktree survive checkout entirely. Earlier rounds named further entrances of the same unbounded surface (grafts, the reference-transaction hook, insteadOf+sshCommand, credential.helper); the forged-base variant via insteadOf was refuted this round (the walk's ancestry check forces an honest merge base). The surface has no last corner: close it structurally — wire .github/scripts/resanitize-git-config.sh (the repository's allowlist reset: remove the redirect files, then unset every repo-local key outside a known-safe allowlist) before the gate's first git call — instead of extending the denylist.
Witness:
planted uploadpack + insteadOf (gate run, all isolation in place):
SENTINEL uploadpack-ran FIRED
--- uploadpack env --- GH_TOKEN=present --- gh calls: 0 ---
reason=pr head fetch failed
config.worktree-only plant (scrub bypass):
enum-exit=1 SENTINEL merge-driver-ran FIRED skip=true
include.path plant (survives actions/checkout):
enum-exit=1 SENTINEL merge-driver-ran FIRED skip=true
Replace the denylist scrub with the repository's existing allowlist reset before the gate's first git call — stage resanitize-git-config.sh to RUNNER_TEMP per its header contract (or inline its sweep) — and update the header's closure claim to match:
REASON='workspace git config sanitization failed'
bash "${RUNNER_TEMP}/resanitize-git-config.sh" || returnThe fix must not violate .github/scripts/resanitize-git-config.sh:26-29 — the redirect files (.git/commondir, .git/shallow, config.worktree) are removed before the allowlist sweep, and the sweep preserves remote\..+\.(url|fetch|pushurl), or the gate's own fetches break. Extend plantAttackChannels() in scripts/tests/qwen-pr-review-workflow.test.js to also plant remote.origin.uploadpack and a config.worktree-only driver, asserting the payload sentinel never fires — removing uploadpack from the sanitizer's removal set (or reverting to the denylist) must turn that test red.
中文说明
本提交的头部声称"整个植入配置类已关闭,而非逐个入口封堵",但该封堵只是针对 git config --local 键的拒绝清单,对复用的自托管工作区——即头部明确指出的威胁模型——仍存在活的入口,已在本 head 上通过执行提交脚本验证。植入的 remote.origin.uploadpack(不被清洗正则匹配)会在门自身的无条件 git fetch 上执行,且发生在任何台账查询之前:在这个携带 PAT 的步骤里、每次门运行时都会执行任意代码,与台账状态无关。仅植入 .git/config.worktree 的键对 --local 枚举不可见,因此清洗"成功"的同时 merge-tree 执行了植入的合并驱动,门还在载荷运行之上输出了 skip=true。同样的绕过经由 include.path 再次打开——actions/checkout 从不清除它,清洗也从不通读它——工作区之外的载荷文件可完整存活过 checkout。更早轮次已指出同一无界表面的更多入口(grafts、reference-transaction 钩子、insteadOf+sshCommand、credential.helper);经由 insteadOf 的伪造 base 变体在本轮被证伪(行走的祖先检查强制要求诚实的 merge base)。该表面不存在最后一个角落:请做结构性关闭——在门的第一个 git 调用之前接入 .github/scripts/resanitize-git-config.sh(仓库已有的允许清单重置:先移除重定向文件,再清掉已知安全允许清单之外的所有仓库本地键),而不是继续扩展拒绝清单。
证据:植入 uploadpack + insteadOf 后执行门(全部隔离措施就位):SENTINEL uploadpack-ran FIRED,环境含 GH_TOKEN=present,gh calls: 0,reason=pr head fetch failed;仅 config.worktree 植入(绕过清洗):enum-exit=1 SENTINEL merge-driver-ran FIRED skip=true;include.path 植入(存活过 actions/checkout):enum-exit=1 SENTINEL merge-driver-ran FIRED skip=true。
修复:在门的第一个 git 调用之前,用仓库现有的允许清单重置替换拒绝清单清洗——按其头部契约把 resanitize-git-config.sh 暂存到 RUNNER_TEMP(或内联其清扫逻辑)——并同步修正头部的"类已关闭"声明。修复不得违背 .github/scripts/resanitize-git-config.sh:26-29:重定向文件(.git/commondir、.git/shallow、config.worktree)必须先于允许清单清扫被移除,且清扫须保留 remote\..+\.(url|fetch|pushurl),否则门自身的 fetch 会失败。请在 scripts/tests/qwen-pr-review-workflow.test.js 中扩展 plantAttackChannels(),追加植入 remote.origin.uploadpack 与仅 config.worktree 的驱动,断言载荷哨兵永不触发——从清理器的移除集合中去掉 uploadpack(或回退到拒绝清单)必须使该测试变红。

[Critical] R4-2: [certifies-falsely] [new-surface] The gate's base identity is still the ref NAME only: a rewrite of the same-named base branch since the reviewed round slips through this check, because both merge bases below recompute against the rewritten live base, so digest equality holds by construction while the landed three-dot diff GAINS content the reviewed round never saw. Executed replay at this head: a round reviews head R against main; a maintainer resets main backward (incident revert of a bad commit) and advances with different commits; the author's update-branch merge passes the walk and the gate emits skip=true while the landed diff gains the dropped commits' content, riding back into main with no automatic round ever covering it. The retarget defence does not transfer: it catches a ref rename, not a same-name rewrite. No gate-only fix exists: record the base COMMIT the round reviewed against (its merge-base) in the ledger marker beside base (writer side, packages/cli — outside this PR's footprint), and require here that it is still an ancestor of the live base tip — monotonic advance keeps skipping, any rewrite fails open. Latent only until the marker writer emits base (the R2-4 gap), then live.
Witness:
rebased_base replay (real git + stubbed gh, marker sha=R base=main):
skip=true
landed three-dot diff after the rewrite gains: other.txt | 2 +- ; z.txt | 1 +
(the sole genuine PR change was f.txt)
Gate side, once the writer emits the base commit:
git merge-base --is-ancestor "$REVIEWED_BASE_SHA" "origin/${BASE_REF}" 2>/dev/null || returnThe base-commit field rides the ledger marker, capped by LEDGER_MAX_BYTES = 8192 (packages/cli/src/commands/review/lib/ledger.ts:583), and must shed with the anchor pair. Add an executed rebased_base fixture — after the round reviews R, reset the origin base backward, add a commit, merge into the PR branch, assert skip=false; it is red today and pins the ancestor check once it lands.
中文说明
门对 base 的认证仍然只认分支名字:已评审轮次之后同名 base 分支被重写,可以穿过这一检查——因为下方两个 merge-base 都相对重写后的活 base 重算,摘要等式按构造成立,而落地的三点 diff 却新增了已评审轮从未见过的内容。已在本 head 执行的复现:某轮在 main 上评审 head R;维护者把 main 向后重置(事故回滚坏提交)并以不同提交继续;作者的 update-branch 合并通过行走,门输出 skip=true,而落地 diff 携带被丢弃提交的内容借由本 PR 回到 main,没有任何自动轮覆盖过它。改道(retarget)防御无法迁移到这里:它拦的是分支改名,不是同名重写。不存在仅门侧的修复:需在台账标记中与 base 一并记录该轮评审所用的 base 提交(其 merge-base)(写入端位于 packages/cli,在本 PR 足迹之外),并在门中要求它仍是活 base 顶端的祖先——单调前进照常跳过,任何重写都向开放侧倒。当前仅在标记写入端补齐 base(即 R2-4 缺口)之前处于潜在状态,之后即为活通道。
证据:rebased_base 复现(真实 git + 打桩 gh,标记 sha=R、base=main):skip=true;重写后落地的三点 diff 新增 other.txt | 2 +- 与 z.txt | 1 +(真正的 PR 改动只有 f.txt)。
门侧在写入端补齐 base 提交后:git merge-base --is-ancestor "$REVIEWED_BASE_SHA" "origin/${BASE_REF}" 2>/dev/null || return。base 提交字段随台账标记携带,受 LEDGER_MAX_BYTES = 8192(packages/cli/src/commands/review/lib/ledger.ts:583)约束,必须与锚点对同进退。请新增执行的 rebased_base 夹具——轮次评审 R 之后,把 origin base 向后重置、追加一个提交、合入 PR 分支,断言 skip=false;该测试今天即为红,祖先检查落地后即被钉住。

[Critical] R11-1: [certifies-falsely] [new-surface] The base-refresh note this step posts goes out as qwen-code-ci-bot — the exact account qwen-autofix.yml defines as REVIEW_BOT (line 87) and deliberately counts as actionable feedback — but it lacks the exclusion every sibling non-actionable bot note carries: qwen-review-base-refresh appears in none of qwen-autofix.yml's eleven non-actionable-marker filter sites at this head (grep exits 1), while the sibling qwen-review-ack IS excluded in each. Once the gate can skip, an engaged PR receiving this note has it counted by N_ISSUE_COMMENTS (qwen-autofix.yml:3411-3421) and spends a full no-action autofix round per base refresh on a note naming nothing to fix. The fix lives entirely in qwen-autofix.yml — outside this PR's three-file footprint: add the marker to the exclusion alternation at every filter site admitting REVIEW_BOT issue comments.
Witness:
grep -c 'qwen-review-base-refresh' .github/workflows/qwen-autofix.yml -> 0 (exit 1)
filter sites checked: 3123, 3173, 3404, 4304, 4392, 4595, 4628, 4705, 4826, 4941, 6226
sibling exclusion present at each: qwen-review-ack
upsert control probe: note POSTed under the step token (REVIEW_BOT account)
In qwen-autofix.yml, add qwen-review-base-refresh beside the existing qwen-review docs-only-medium exclusion at every filter copy admitting REVIEW_BOT issue comments (BOT_COMMENT_FILTER at line 3404 and its inline copies). qwen-autofix.yml:3404 — BOT_COMMENT_FILTER has inline copies; a single missed copy keeps the round-spending live. Pair the new exclusion with a static assertion alongside the qwen-review docs-only-medium exclusion so a one-sided rename of the marker turns it red.
中文说明
本步骤发布的 base 刷新说明以 qwen-code-ci-bot 名义发出——正是 qwen-autofix.yml 定义为 REVIEW_BOT(第 87 行)并被刻意计为可执行反馈的账号——但它缺少每条同类非执行机器人说明都携带的排除项:在本 head 上,qwen-review-base-refresh 在 qwen-autofix.yml 的十一处非执行标记过滤位置中一处都没有出现(grep 退出码 1),而同类的 qwen-review-ack 在每一处都被排除。一旦门可以跳过,收到该说明的 engaged PR 会被 N_ISSUE_COMMENTS(qwen-autofix.yml:3411-3421)计入,从而每次 base 刷新都为一条没有可执行内容的说明花掉一整轮空转的 autofix。修复完全位于 qwen-autofix.yml——在本 PR 的三文件足迹之外:在所有接受 REVIEW_BOT issue 评论的过滤位置把该标记加入排除交替组。
证据:grep -c 'qwen-review-base-refresh' .github/workflows/qwen-autofix.yml → 0(退出码 1);已核对过滤位置:3123、3173、3404、4304、4392、4595、4628、4705、4826、4941、6226;每处均存在同类排除项 qwen-review-ack;upsert 对照探针:说明以步骤令牌(REVIEW_BOT 账号)成功 POST。
修复:在 qwen-autofix.yml 中,所有接受 REVIEW_BOT issue 评论的过滤副本(第 3404 行的 BOT_COMMENT_FILTER 及其内联副本)处,把 qwen-review-base-refresh 加入现有 qwen-review docs-only-medium 排除项之旁。qwen-autofix.yml:3404——BOT_COMMENT_FILTER 存在内联副本,漏掉任何一处都会让空转轮次继续发生。请把新排除项与 qwen-review docs-only-medium 排除项以静态断言配对,使标记被单边改名时该断言变红。

What this PR does
Adds a deterministic gate to the automatic PR review pipeline that recognizes a base-refresh-only push and skips the review round it would otherwise spend. When a
synchronizeevent arrives on the automatic path, the gate certifies two facts before any review compute is allocated: every first-parent commit since the head the last completed automatic round reviewed is a two-parent merge of the base branch, and the pull request's own three-dot diff is unchanged — established by patch-id equality, which ignores hunk offsets but hashes content and context lines, so an upstream change that touches the PR's own hunks (or their surrounding context) breaks the equality and the full round runs. When both facts hold, the review-spending steps are skipped and a single marker-deduped note on the PR says the previous review still applies, updated in place on later refreshes, with a pointer to@qwen-code /reviewfor anyone who wants a fresh full round anyway.The reviewed head is taken from the newest ledger-marked review posted by the pipeline's own account, resolved live from the token — the same norm the fallback dedup uses — so a participant posting the marker text in their own review can never certify a head the gate would skip past. Everything in the gate fails open: any probe error, any lookup failure, and any shape that does not match (a real commit riding the refresh, a merge of a non-base branch, an octopus merge, a force-push that retired the reviewed head, a changed PR-side diff, or more than ten first-parent steps since the reviewed head) proceeds with the full round. The gate step never exits non-zero and carries
continue-on-error, so a crash inside it can neither kill the job nor make the fallback comment misreport the skip as a pipeline failure. Explicitly requested reviews — the@qwen-code /reviewcommands,review_requested, andworkflow_dispatch— are not gated.Why it's needed
An update-branch base refresh (the loop merging current
maininto the PR branch after a red check clears, or the button in the UI) firessynchronizelike any push, and the automatic review treated it as a full new round — a multi-hour, full-cost re-review of a head whose PR-side delta is zero. On PR #9729 two base refreshes spent one full ~3.5h round plus one partially-run cancelled round for zero PR-side change. The incremental path does not neutralize this by itself: the merge commit moves the merge base, and on busy PRs the anchor chain or the import widening turns such a round into a near-full re-read anyway.Reviewer Test Plan
How to verify
The gate's bash runs unmodified inside the new test suite against real git repositories in every shape it must decide, with only the GitHub API stubbed:
cdinto the repo root and runnpx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/qwen-pr-review-workflow.test.js -t 'base-refresh'— twelve cases: skip on a single refresh and on two consecutive refreshes, skip when upstream touched the same file far from the PR's hunks (offset insensitivity), note posted once and PATCHed in place on the next refresh, and full-round fall-through for a real commit riding the refresh, a context-touching merge, a non-base merge, a force-push, a marker review from another account, an unmarked review, and dead API lookups (exit 0, fail open). Then confirm the wiring: the four review-spending steps all carry the skip guard, and the existing suites that pin this workflow's shape still pass.What a reviewer should confirm in the workflow diff: the gate only fires on the automatic
synchronizepath (explicit review requests are untouched), the skip output defaults open when the step is skipped or crashes, and the reviewed-head lookup is scoped to the authenticated account plus the ledger marker rather than a hardcoded login alone.Evidence (Before & After)
N/A — CI workflow behavior; no TUI surface. Before: a base refresh on PR #9729 started a full review round (run 32674762912, ~3.5h) and a second one started and was cancelled (run 32875478404). After: the same shape produces
skip=truewith the reviewed head recorded, a one-line note on the PR, and no review compute spent — exercised by the test suite'supdate_branch_onlyandtwo_refreshesshapes.Tested on
Environment (optional)
Unit tests only (
npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/qwen-pr-review-workflow.test.js); the executed-bash cases skip themselves on Windows and jq-less hosts, and three pre-existing failures in unrelated suites (chmod-based lock probes that cannot hold as root) reproduce identically on a clean checkout.Risk & Scope

中文说明
这个 PR 做了什么
为自动 PR 评审流水线加入一个确定性门:识别"仅刷新 base"的 push,并跳过它原本会花掉的整轮评审。自动路径上收到
synchronize事件时,门在分配任何评审算力之前先确证两件事:自上一次完成的自动评审轮所覆盖的 head 以来,每个 first-parent 提交都是对 base 分支的双亲合并;且 PR 自身的三点 diff 未变——用 patch-id 相等性判定,它忽略 hunk 偏移但哈希内容与上下文行,因此上游改动一旦触及 PR 自己的 hunks(或其上下文),相等性即被打破,完整轮次照常运行。两个事实都成立时,跳过消耗评审算力的步骤,并在 PR 上留一条带 marker 去重的说明(后续刷新原地更新),指明原评审结论仍然适用,想要全新评审可评论@qwen-code /review。"已评审 head"取自流水线自身账号发布的最新带台账 marker 的 review,账号由 token 实时解析——与 fallback 去重同一规范——因此参与者在自己的 review 里贴 marker 文本无法让门跳过任何 head。门内一切失败都向开放侧倒:任何探测出错、任何查询失败、任何不匹配的形态(刷新中夹带真实提交、合并了非 base 分支、octopus 合并、force-push 使已评审 head 失效、PR 侧 diff 变化、或距已评审 head 超过十个 first-parent 提交)都会继续跑完整轮次。门步骤永不以非零退出并带
continue-on-error,内部崩溃既不会挂掉 job,也不会让 fallback 评论把跳过误报为流水线故障。显式请求的评审——@qwen-code /review命令、review_requested、workflow_dispatch——不经过此门。为什么需要
update-branch 式 base 刷新(循环在红色检查恢复后把当前
main合入 PR 分支,或 UI 上的按钮)会像普通 push 一样触发synchronize,自动评审将其当作全新一轮——对一个 PR 侧 delta 为零的 head 做数小时的全价 re-review。PR #9729 上两次 base 刷新花掉了一个约 3.5 小时的完整轮次外加一个中途被取消的轮次,而 PR 侧没有任何变化。增量路径自身抵消不了它:merge commit 移动了 merge base,在繁忙 PR 上锚点链或 import 加宽本来就会把这样的轮次变成近全量重读。评审者测试计划
如何验证
门的 bash 原样运行在新测试套件里,对着真实 git 仓库覆盖它必须裁决的每种形态,只有 GitHub API 被打桩:在仓库根目录运行
npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/qwen-pr-review-workflow.test.js -t 'base-refresh'——共十二个用例:单次刷新与连续两次刷新时跳过、上游改动同文件远处(偏移不敏感)时跳过、说明只发一条且下次刷新原地 PATCH,以及各种回落到完整轮次的形态:刷新中夹带真实提交、触及上下文的合并、非 base 合并、force-push、他人账号的 marker review、无 marker 的 review、API 查询全挂(exit 0,fail open)。再确认接线:四个消耗评审算力的步骤都带上了跳过守卫,既有的 workflow 形态 pin 套件仍然通过。评审者在 workflow diff 里应确认:门只在自动
synchronize路径生效(显式评审请求不受影响)、步骤被跳过或崩溃时 skip 输出默认向开放侧倒、已评审 head 的查询以认证账号加台账 marker 为准而非仅凭硬编码登录名。证据(Before & After)
N/A —— CI workflow 行为,无 TUI 界面。Before:PR #9729 上一次 base 刷新启动了完整评审轮(run 32674762912,约 3.5 小时),另一次启动后被取消(run 32875478404)。After:同一形态产出
skip=true并记录已评审 head,PR 上留一行说明,不再花评审算力——由测试套件的update_branch_only与two_refreshes形态覆盖。本地测试环境
仅单元测试(
npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/qwen-pr-review-workflow.test.js);执行 bash 的用例在 Windows 与无 jq 的主机上自动跳过,另有三个无关套件的既有失败(基于 chmod 的锁探测在 root 下不成立)在干净检出上同样复现。风险与范围
