Autofix E2E Report — issue #12006

Issue

Main-branch E2E run 35069321648 on aff26a8f36 failed the E2E Test (Linux) - sandbox:docker - shard 1/1 job in the steps Run E2E tests and Prune dangling docker images.

Diagnosis (evidence)

• The public jobs API shows both failed steps completed in under one second (07:46:47 → 07:46:47) — no test, build, or prune actually ran. The sibling sandbox:none leg and both macOS legs passed, so the commit's own E2E test changes were not the trigger.
• The job's only annotation besides the two exit code 1 failures was the Restore workspace ownership step warning: could not restore CI cache ownership; docker sandbox locks may stay unreadable. That heal (added by fix(ci): heal the docker lock cache ownership in e2e-test-linux (#11990) #11992 for Main CI failed: E2E Tests on dfad77be8c66 #11990) chains chown … || sudo -n chown …; a non-root runner can never chown a root-owned file, and this pool runner has no passwordless sudo, so the heal warned and gave up.
• Both failed steps open the same host-side flock file with a write redirection under set -e/bash -e: exec 9>"${HOME}/.cache/qwen-code-ci/docker-sandbox-daemon.lock" (in .github/scripts/run-e2e-tests.sh for the test step, and in e2e.yml for the prune step). A root-owned leftover there fails the open with EACCES and kills the step before any work — exactly the observed 0-second deaths.

Reproduction

Docker is not available in this autofix container, so the exact CI leg cannot run here. Instead the failure was reproduced at bash level by executing the real run-e2e-tests.sh (docker branch, RUNNER_ENVIRONMENT=self-hosted, stubbed docker/npx) against a $HOME/.cache/qwen-code-ci/docker-sandbox-daemon.lock made unwritable (chmod 0400):

• Pre-fix script: run-e2e-tests.sh: line 46: …/docker-sandbox-daemon.lock: Permission denied, exit 1 — the same instant death as the CI steps.
• Post-fix script: the leg runs to completion (exit 0) on a job-private lock dir, emitting a ::warning:: about the degraded coordination.

Fix

Both lock-opening call sites now resolve the lock directory through a new helper, .github/scripts/resolve-ci-lock-dir.sh, instead of hardcoding ${HOME}/.cache/qwen-code-ci. The helper prints the shared dir when it is usable (mkdir succeeds, dir writable, every existing *.lock writable); otherwise it prints a job-private fallback under $RUNNER_TEMP and warns. Losing cross-job coordination on a degraded host is safe: the sandbox image build is idempotent, and both prune paths are label- and age-filtered (until=24h), so they never touch an image a running leg could be using. When the host is healthy (or the heal step can chown, e.g. where sudo exists), behavior is byte-for-byte the old shared-dir protocol.

The heal step itself is unchanged — it still restores full coordination where it has the privileges. .github/scripts/run-release-docker-integration.sh and sdk-java.yml open locks in the same shared dir and remain exposed to the same host-state failure; they are separate workflows and were left untouched to keep this fix scoped (noted for follow-up).

Regression coverage

scripts/tests/resolve-ci-lock-dir.test.js (new, bash-executed, excluded on Windows like the other bash-driven suites) witnesses: resolver prefers the shared dir when writable; falls back on an unwritable lock file; falls back on an unwritable dir; the full docker branch of run-e2e-tests.sh completes on the shared dir when healthy; and — the #12006 reproduction — completes via the job-private fallback when the daemon lock is unwritable. A mutation probe confirmed the reproduction test fails against the pre-fix script (exit 1, EACCES) and passes with the fix. scripts/tests/e2e-workflow.test.js pins were updated to the new ${ci_lock_dir} shape and now also pin that both call sites resolve through the helper before opening any descriptor.

Verification

• Reproduction probe (pre-fix script, unwritable lock file): exit 1 with …/docker-sandbox-daemon.lock: Permission denied — matches the CI failure signature.
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/resolve-ci-lock-dir.test.js scripts/tests/e2e-workflow.test.js scripts/tests/e2e-shard-retry.test.js — 47 passed.
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/resolve-ci-lock-dir.test.js scripts/tests/e2e-workflow.test.js scripts/tests/e2e-shard-retry.test.js scripts/tests/release-workflow.test.js scripts/tests/unit-vitest-configs.test.ts — 165 passed.
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/sdk-java-workflow.test.js scripts/tests/no-ak-integration-ci.test.js — 19 passed.
• Mutation probe: witness test re-run against the pre-fix run-e2e-tests.sh — fails with exit 1 (EACCES) as expected; restored script passes.
• bash .github/scripts/check-workflow-size.sh — passed (e2e.yml stays within the 4096-byte growth allowance; the qwen-autofix.yml size warning is pre-existing on main).
• shellcheck 0.11.0 with the repo's flags (--check-sourced --enable=all --exclude=SC2002,SC2129,SC2310 --severity=style) — new helper is clean; run-e2e-tests.sh shows only the 3 pre-existing warnings, zero new findings.
• actionlint 1.7.12 with the repo's flags on .github/workflows/e2e.yml — clean.
• npx prettier --experimental-cli --check on all changed files — passed (after --write normalized the two test files).
• npx eslint scripts/tests/vitest.config.ts scripts/tests/e2e-workflow.test.js scripts/tests/resolve-ci-lock-dir.test.js — passed.
• npm run lint — passed.
• npm run typecheck — passed.
• npm run build — passed.
• npm run test:scripts (full scripts suite) — 2494 passed, 17 skipped, 1 failed: scripts/tests/verify-capture.test.js > preserves colour and bold independently. Reproduced identically on clean HEAD with all changes stashed, so it is a pre-existing, environment-specific failure of this container (bold ANSI rendering), unrelated to this change.
• Not run locally: yamllint (no pip/pip3/uv in this container; the 2-line YAML edit preserves indentation and quoting, and actionlint parsed the document cleanly) and the real docker E2E leg (no docker daemon available; bash-level surrogate described above). The next main-branch E2E run is the end-to-end confirmation.

Autofix review round — PR #12016

Addressed all 7 findings from the latest review (1 Critical + 6 Suggestions). No declines, no deferrals, no open questions.

Findings

R1-1 [Critical] — docker-leg test cases fail where flock is absent (rc:4025497745)

Implemented. Reproduced before fixing: with a PATH farm containing every real binary except flock, the suite failed exactly as reported — 2 failed | 3 passed, both docker-leg cases dying at flock --shared --wait 1800 9 (bash 127 → ::error::docker daemon read lock not acquired within 30 minutes → exit 1). Fix per the suggestion: an exit 0 flock stub in world.bin beside the existing docker/npx stubs — these cases witness lock-DIR resolution, not lock semantics — so the #12006 reproduction stays executed, not skipped, on every lane including test_macos. run-e2e-tests.sh is untouched (the flock --shared --wait 1800 9 pin stands) and nothing was added to the win32 exclusion list.

R1-3 [Suggestion] — a foreign unwritable lock vetoes the shared dir (rc:4025497777)

Implemented. ci_lock_dir_writable now takes the names of the locks the caller will open and probes only those; the directory-level checks stay unconditional, so an unwritable directory still always falls back. run-e2e-tests.sh passes docker-sandbox-daemon.lock docker-sandbox-build.lock "docker-sandbox-build-e2e-${GITHUB_SHA}.lock"; the prune step passes docker-sandbox-daemon.lock; both text pins were updated in the same change. New case: an unwritable runner-owned sdk-java-tests.lock beside a writable daemon lock → the resolver still prints the shared dir (red before, green after). No rm-based healing — lock identity lives on the inode.

R1-2 [Suggestion] — per-job fallback silently drops coordination; the header overclaims (rc:4025497792)

Implemented the "cheapest honest fix" arm. The header now states that coordination with sibling jobs, the root qwen-docker-cleanup timer, and the release lane's build mutex is lost, not merely degraded; that the until=24h age filter does not protect a reused image; and that clearing the state needs a human on the host. When GITHUB_STEP_SUMMARY is set, the resolver also appends the notice there, so the degradation lands on the run page instead of only in a step log. I did not take the host-shared-fallback arm: it adds a second lock namespace to reason about and still cannot restore coordination with the root timer (which keys on the primary path), so it buys little over honesty for a state that should be rare and human-cleared anyway.

R1-4 [Suggestion] — prune step dies at 127 when checkout failed (rc:4025497806)

Implemented. The always()-gated prune step now carries the suggested || { ci_lock_dir="${RUNNER_TEMP:-/tmp}/qwen-code-ci-locks"; mkdir -p ...; } guard, with a comment noting the softening belongs to this step only — the test leg keeps failing loudly. Verified behaviorally in an empty workspace under bash -e: with the guard the step exits 0 and both prunes run; without it the step aborts at 127 and no prune runs.

R1-7 [Suggestion] — the fail-loud branch had no test (rc:4025497840)

Implemented. New case fails loudly when the job-private fallback cannot be created: shared dir at 0555, RUNNER_TEMP under a regular file → asserts exit 1, empty stdout, and ::error:: on stderr. (One deviation from the snippet: the shared dir is made unwritable before the spawn, otherwise the resolver takes the primary branch and never reaches the fallback.)

R1-8 [Suggestion] — the warning asserted an unverified root-owned cause (rc:4025497849)

Implemented. The probe now records why it failed on each exit — cannot create <dir> / <dir> is not writable / lock file <path> is not writable — and the warning and error name the offending path. The hardcoded (unhealed root-owned leftover) is gone. The existing lock-file fallback case now asserts the warning names docker-sandbox-daemon.lock; stdout remains exactly one line — the resolved path — for both callers' $(...) capture.

R1-6 [Suggestion] — exec 8> was not pinned to the resolved dir (rc:4025497864)

Implemented. The bare filename-fragment pin is now the full line exec 8>"${ci_lock_dir}/docker-sandbox-build-e2e-${GITHUB_SHA}.lock" (the commit-qualified name stays), and a new behavioral case poisons the shared directory (0555), runs the docker leg with the image absent, and asserts exit 0 plus all three lock files — daemon, per-commit coordinator, build mutex — created under the job-private fallback. Exercising the build-mutex path required stubbing npm and making the docker stub report the image absent.

Mutation probes

Each run against this round's tree and restored afterwards (restores verified byte-identical):

• Drop the flock stub and run with the flock-less PATH farm → all 3 docker-leg cases red; the suite is green again with the stub on the same farm (the macOS condition).
• Remove the resolver's named-lock probe loop → falls back ... when a lock file is not writable and the docker-leg lock-file case red — the narrowing is not a no-op.
• Revert exec 8> to the ${HOME}/.cache/qwen-code-ci spelling → the new toContain pin AND the directory-poisoning behavioral case both red.
• Delete the fail-loud exit 1 → the new fail-loud case red (previously green, per the finding).
• Drop the filename from the per-lock warning → the naming assertion red.
• Remove the $GITHUB_STEP_SUMMARY block → the step-summary case red.
• Remove the prune step's || guard → the guard pin red.

Red-before/green-after witnesses (new assertions against the pre-fix scripts): the foreign-lock case, the step-summary case, the warning-names-the-file assertion, and all three updated/new e2e-workflow.test.js pins were red; everything went green after the script changes.

Verification

• npm run build — passed
• npm run typecheck — passed
• npm run lint — passed (eslint; the repo's shellcheck lane is lint:all, which downloads the binary and cannot run in this sandbox — both shell scripts pass bash -n and follow the repo's shellcheck-clean conventions)
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/resolve-ci-lock-dir.test.js scripts/tests/e2e-workflow.test.js scripts/tests/e2e-shard-retry.test.js scripts/tests/no-ak-integration-ci.test.js — 66 passed
• node --test .github/scripts/ci-runner-routing.test.mjs — 23 passed
• npm run test:scripts (full scripts suite) — 2499 passed, 1 failed: verify-capture.test.js > preserves colour and bold independently, a terminal-ANSI rendering assertion reproduced identically on the pre-round tree via a stash probe; it is unrelated to any file this PR touches. (install-script.test.js also failed before npm run build for want of packages/audio-capture/dist in this environment and is green after it.)
• flock-less PATH farm (/tmp/no-flock-farm: 540 entries = every real PATH binary minus flock) — resolver suite green with the stub, i.e. under the macOS-lane condition.
• npx prettier --check on all touched files — clean.

Autofix round summary — PR #12016 (issue #12006)

Commit: f341329b9a fix(ci): keep the docker prune exclusion on the shared daemon lock (#12006)

All seven open inline findings — two Criticals (R1-4 twice, R3-1) and two Suggestions (R1-8 twice, R2-1 twice) — are addressed in one coherent change: the daemon-lock coordination channel is now resolved and used identically by both call sites, and every new guard carries a mutation-proven witness.

R1-4 (Critical, e2e.yml:335 — job-private fallback defeats the prune exclusion) — implemented

The || { … } guard no longer invents a job-private lock directory. When the resolver cannot run (Checkout failed → 127), the step probes the shared ${HOME}/.cache/qwen-code-ci inline — it needs no checked-out file, which is why the pre-diff code worked on that path. A second guard line then blanks ci_lock_dir whenever it is not exactly the shared dir, so the labelled docker image prune --all runs only when the daemon lock genuinely lands on the shared path every leg, the host cleanup timer and the release lane coordinate on; otherwise the step takes its own else branch ("Docker cleanup skipped because the shared daemon is active"). The dangling prune moves out of the if and stays unconditional, as the finding allows — dangling images are untagged and unreferenced, so no exclusion is needed. The resolver's stderr is deliberately not silenced: ci-runner-routing.test.mjs pins doesNotMatch(run, /\/dev\/null/), so the suggested 2>/dev/null was replaced by letting mkdir's own error surface in the step log (which is what that pin's comment asks for — a failing prune must stay diagnosable). exec 9> sits inside the if condition; probed on bash: a redirection failure there becomes condition-false, not a script abort, so a dir-writable-but-lock-file-poisoned host degrades to a skip instead of a red step.

Pins moved in the same change: it('still prunes when the resolver itself cannot run') now pins the shared-dir inline probe instead of the job-private spelling; new pins assert the skip-on-non-shared guard line and the combined if [ -n … ] && exec 9>… && flock --nonblock 9 shape. New bash-driven suite prune step daemon lock discipline in scripts/tests/resolve-ci-lock-dir.test.js executes the step body extracted from the parsed e2e.yml under bash -e with stubbed docker/flock: with the resolver absent on a healthy host the lock lands on ${HOME}/.cache/qwen-code-ci/docker-sandbox-daemon.lock and the labelled prune runs; with the resolver present and the shared dir poisoned the resolver returns the job-private fallback and no labelled-prune argv is recorded (the dangling prune still runs). The lock path is witnessed through the file exec 9> creates rather than a path-recording flock stub, because a flock stub cannot see fd-target paths portably (no /proc on macOS) — the created file is the same evidence.

R3-1 (Critical, e2e.yml:333 — leg and prune resolve the daemon lock with different name sets) — implemented

The leg now resolves the coordination channel on its own:

ci_lock_dir="$(bash .github/scripts/resolve-ci-lock-dir.sh docker-sandbox-daemon.lock)"
ci_build_lock_dir="$(bash .github/scripts/resolve-ci-lock-dir.sh docker-sandbox-build.lock "docker-sandbox-build-e2e-${GITHUB_SHA}.lock")"

exec 9> (daemon read lock) stays on ${ci_lock_dir}; exec 8> (per-SHA coordinator) and exec 7> (build mutex) move to ${ci_build_lock_dir}. A poisoned build-family lock now costs only the build mutex — the leg still runs, which is this PR's goal — while the daemon lock stays on the shared path, so the prune step's flock --nonblock 9 correctly loses to a live leg and skips. The per-name probe contract (an unwritable sdk-java-tests.lock must not veto) is unchanged. Pins at e2e-workflow.test.js moved byte-for-byte in the same change, including the ordering pins (both resolutions precede every exec).

New witnesses: a resolver-level case (it.skipIf(isRoot)) poisoning only docker-sandbox-build.lock while the daemon-lock probe still resolves the shared dir, and a runDockerLeg case asserting the daemon lock file lands under the shared dir while both build-family locks land under ${RUNNER_TEMP}/qwen-code-ci-locks (image absent, so the build-mutex exec 7> path runs).

R1-8 (Suggestion, resolve-ci-lock-dir.sh:36 — cannot create message unpinned) — implemented

New case names the cause when the shared dir cannot be created: HOME points under a regular file so the primary mkdir -p fails ENOTDIR, and the case asserts stderr contains cannot create while stdout still carries the job-private fallback. ENOTDIR fails for root too, so the case needs no isRoot skip — this deviates from the suggested it.skipIf(isRoot) spelling deliberately, mirroring the same reviewer's R2-1 reasoning that ENOTDIR poisoning is uid-independent; the acceptance mutation (replace the message string) was run and reddens only this case.

R2-1 (Suggestion, run-e2e-tests.sh:41 — no witness that the leg fails loudly) — implemented

runDockerLeg now accepts home/runnerTemp env overrides. New case fails loudly when no lock directory can be created poisons both HOME and RUNNER_TEMP by ENOTDIR (regular file in the path — no isRoot skip needed) and asserts exitCode != 0, ::error:: in the output, and that the output never mentions /docker-sandbox-daemon.lock — the last assertion is what reddens if the prune step's || guard is copied into the leg "for symmetry" (the leg would otherwise open the daemon lock at the filesystem root). Because the leg now has two resolver calls, the single-line mutation is masked by the second call's failure under set -e; the realistic both-lines edit is what the probe covers, and a lane-independent text pin in e2e-workflow.test.js (not.toMatch(/resolve-ci-lock-dir\.sh[^\n]*\)"\s*\|\|/)) covers either line alone. set -euo pipefail is now also pinned (toMatch(/^set -euo pipefail$/m)). No assertion on the absence of the root-anchored FILE — on a root lane the mutant would create it, which would test the host, not the change.

Mutation probes (all run, all restored to green)

• R1-8: problem="cannot create ${dir}" → "MUTANT-CANNOT-CREATE" → only the new case fails (1 failed / 14 passed).
• R3-1: re-couple the leg to one three-name probe → keeps the daemon lock shared when only a build lock is poisoned fails (1/14).
• R1-4a: restore the job-private fallback in the || { group → locks the shared dir and prunes when the resolver itself cannot run fails (1/14).
• R1-4b: delete the skip-on-non-shared guard → skips the labelled prune when the shared dir is poisoned fails (1/14).
• R2-1a: append || ci_lock_dir='' to both leg resolver calls → both the new leg case and the new text pin fail.
• R2-1b: drop set -euo pipefail → both the pipefail pin and the new leg case fail.

Notes

• The review-body item "neither discriminating input of the per-name writability probe is tested" was explicitly deferred by the reviewer under the convergence posture ("recorded, not requested in this round") and is not addressed here.
• scripts/tests/verify-capture.test.js (preserves colour and bold independently) fails in this sandbox; reproduced identically with this round's changes stashed, so it is pre-existing and unrelated (terminal-rendering capability detection, nothing near the touched files).
• The e2e.yml yamllint lane could not run locally (no pip/yamllint in this runner image); the change is confined to a run: |- block scalar (exempt from indentation checks via check-multi-line-strings: false), and trailing-space / comment-spacing / EOF-newline rules were verified by inspection. shellcheck (extracted from the lane's pinned tarball) reports no new findings on either touched script vs HEAD, and actionlint passes on e2e.yml.

Verification

• npm run typecheck — passed
• npm run lint — passed
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/resolve-ci-lock-dir.test.js scripts/tests/e2e-workflow.test.js scripts/tests/e2e-shard-retry.test.js — 60 passed

Addressed review feedback — PR #12016 round

All five inline findings from the latest automated review were verified against the code, reproduced where they claimed wrong behavior, and resolved in commit d75b0bb00b (fix(ci): scope the docker cleanup diagnostics to what was probed (#12006)). --conflict false: no merge of main was needed or performed. No test was deleted or weakened — the changed files' assertion counts only grew, so no test-weakening.json is required.

Dispositions

[rc:4031664803] R4-1 — prune step asserted causes it never verified — RESOLVED

Verified before implementing: on the resolver-absent path the inline probe tested only [ -w ] on the directory, so a root-owned 0400 daemon lock failed exec 9> with EACCES inside the if condition (no bash -e abort) and the step exited 0 printing only the false Docker cleanup skipped because the shared daemon is active; on the resolver-fallback path the same message claimed an active daemon while the step's own guard had just discarded the resolver's job-private result; and the resolver's summary banner claimed this job locks in the job-private <dir> for the one caller that opens no lock there.

Changes in .github/workflows/e2e.yml:

• The resolver-absent inline fallback now probes the daemon lock file ([ -e ] && [ ! -w ]), not just the directory, and records skip_reason naming the offending path (.../docker-sandbox-daemon.lock is not writable by this job / cannot create a writable ...).
• The shared-dir guard only fires when the resolver returned a non-shared dir and carries its own reason; the skip line is now Docker cleanup skipped: <observed reason>; clearing ${HOME}/.cache/qwen-code-ci needs a human on this host. The shared daemon is active message survives only on the branch where flock --nonblock actually lost.
• The step's resolver call is GITHUB_STEP_SUMMARY= bash ... so the fallback banner is suppressed for exactly this discarding caller; the leg's two calls keep the banner.
• Running the unconditional dangling prune is announced separately, so a "skipped" line scopes to the labelled prune.

Tests: retargeted skips the labelled prune when the shared dir is poisoned (skip line must name the lock dir and needs a human; not.toContain('shared daemon is active')), added names the unwritable daemon lock when the resolver cannot run (withResolver: false + 0o400 lock in a writable shared dir) and writes no fallback banner for the caller that discards the result (GITHUB_STEP_SUMMARY set; summary stays empty while the labelled prune is skipped). The e2e-workflow.test.js text pins moved with the restructure (blanked resolver call, != guard, elif exec 9>).

[rc:4031664817] R4-2 — no success-direction witness for the resolver/step path agreement — RESOLVED

Verified: runPruneStep(world, { withResolver: true }) was used exactly once and asserted the prune does not run; the healthy path had no behavioral witness. Added locks the shared dir and prunes when the resolver is healthy: clean world, resolver present, asserting exitCode === 0, the daemon lock file exists under the shared ${HOME}/.cache/qwen-code-ci, and dockerArgv contains image prune --all. Kept the string-identity guard (the finding's primary ask is the witness; the flag/exit-status redesign was explicitly the alternative). Guard deletion is caught by the existing poisoned-dir case, so both mutations now have behavioral witnesses.

[rc:4031664822] R4-3 — fallback messages claimed prune coordination loss on build-only fallback — RESOLVED

Verified: the shared template printed docker build/prune coordination on this host is lost and named the qwen-docker-cleanup timer even when only a build-family lock fell back — the state this PR's split made reachable. .github/scripts/resolve-ci-lock-dir.sh now scopes both the ::warning:: and the step-summary sentence to the locks the call actually probed (for: $*; cross-job coordination on these locks is lost for this job), keeping ${problem}, the lock-dir fallback heading, both paths, and the does-not-heal sentence. Extended the leg-level case keeps the daemon lock shared when only a build lock is poisoned with output/summary assertions: names docker-sandbox-build.lock, never matches /prune/. Left the daemon-only resolver case untouched (its stderr is asserted empty there, so a not.toMatch would be vacuous).

[rc:4031664833] R4-4 — unwritable-dir cause text unpinned — RESOLVED

Verified: cause 2 (${dir} is not writable) had no message-text pin and the comment on the cannot create case wrongly claimed it was "pinned above". Added expect(result.stderr).toContain('is not writable') to falls back when the shared dir itself is not writable and to the ::error:: case, and reworded the comment to point at the unwritable-lock pin above and the unwritable-dir pin below.

[rc:4031664844] R4-5 — opened-locks == probed-locks invariant pinned only as literals — RESOLVED

Verified: a lock added to an exec N> line without extending the resolver argument list left every gate green. Added probes exactly the lock files each call site opens in e2e-workflow.test.js: it extracts the opened set from exec \d+>"${ci_lock_dir}/…" / exec \d+>"${ci_build_lock_dir}/…" and the probed set from the matching resolve-ci-lock-dir.sh … invocation (per variable), comparing sorted string sets with ${GITHUB_SHA} unexpanded on both sides — for run-e2e-tests.sh (both variables) and the prune step in e2e.yml.

Mutation probes (guard removed → matching case reddens → restored → green)

Notes

• The review's two convergence-deferred items (2>/dev/null on the primary mkdir -p; the header's per-job RUNNER_TEMP claim) were explicitly "recorded, not requested in this round" and are untouched.
• scripts/tests/ci-runner-routing.test.mjs, cited in R4-1's constraint list, does not exist in this repository; the substance of the constraint (both prune commands, until=24h, || echo "::warning::, no /dev/null silencing) is preserved — the resolver is muted per-call via the GITHUB_STEP_SUMMARY= env prefix, not a redirect.
• Two unrelated scripts-suite failures reproduce identically with this round's changes stashed on the pre-round HEAD: verify-capture helper > preserves colour and bold independently (ANSI rendering) and standalone release packaging > does not package audio-capture test artifacts (create-standalone-package.js smoke run). Neither file reads the scripts this PR touches; both are pre-existing on this runner.

Verification

• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/resolve-ci-lock-dir.test.js scripts/tests/e2e-workflow.test.js — 56 passed (was 52 pre-round; +4 new cases)
• npx vitest run … scripts/tests/e2e-shard-retry.test.js (the third reader of run-e2e-tests.sh) — 8 passed
• npm run test:scripts (full scripts suite) — 2528 passed, 2 failed; both failures reproduced identically on the pre-round tree with this round stashed (pre-existing, unrelated — see Notes)
• npm run build — passed
• npm run typecheck — passed
• npm run lint — passed
• npx prettier --check on the two changed test files and e2e.yml — passed (.sh has no prettier parser)
• bash -n on resolve-ci-lock-dir.sh, run-e2e-tests.sh, and the extracted prune-step body — passed
• Mutation probes — 8/8 reddened the intended witness and were restored to green (table above)

⏸️ AutoFix paused by a review convergence signal: 3 consecutive automated review round(s) signalled machine-readable non-convergence (codes observed since the last maintainer response, or the window start if none: batch-fixes, root-cause-triage, stem-surface) — the reviewer keeps finding new defects at a rate that is not falling while the loop keeps widening the diff, so another automatic round is unlikely to converge this PR. The loop resumes once a maintainer responds on this PR (a review or comment counts, and steers the next rounds), and pauses again if the signal persists for 3 more round(s). Alternatives: split the recurring cluster into its own PR, batch the remaining fixes into one push, comment @qwen-code /retry to re-arm a fresh window, or @qwen-code /takeover to take it over with the raised cap. While paused, new feedback and base conflicts stay unhandled.

Maintainer verification — built the real environment locally and drove this change through it

Verified at head 1cf3bc952b45d9857780b806674ee7564a18f8da (net effect against today's origin/main 8589f713: 6 files, +958/−11, matching the PR description). Verdict: this is safe to land, with one residual risk the standing Critical describes correctly, and two sentences in the PR description that need correcting.

How it was verified

Not by re-reading the diff. A real Linux host was reconstructed and the three step bodies were executed on it, byte-for-byte as the workflow ships them:

• Container: Debian bookworm, real flock (util-linux 2.38.1), uid 2001 github-runner, no passwordless sudo — the hk1/hk2 shape, confirmed in-rig (sudo: a password is required).
• Step bodies: Restore workspace ownership, Run E2E tests and Prune dangling docker images extracted from e2e.yml by YAML parse (no rewriting), run in order under GitHub's default bash --noprofile --norc -e -o pipefail (e2e.yml sets no shell:/defaults: override).
• Arms: origin/main vs the PR merged into it, same rig, same worlds.
• Not real: docker/npm/npx are argv-recording shims, so "what the job asked docker to do" is exact while the image build and vitest payload are not. The one claim that needs a real daemon — R7-1's image loss — was re-run against real Docker 29.5.2 separately.

1. The failure reproduces on main, and the PR fixes it

The main arm emits the production log of run 35069321648 line for line, including the line number: run-e2e-tests.sh: line 46: …/docker-sandbox-daemon.lock: Permission denied, then the prune step's own line 2: copy, both exit 1, no test executed. On the PR arm the same host state gives leg rc=0 · prune rc=0.

Two details of the design hold up under test, and neither is pinned by reading alone:

• A poisoned build lock moves only the build family — the daemon lock stays shared, so the prune exclusion survives (main dies at line 65 in the same world).
• A poisoned sdk-java-tests.lock vetoes nothing, because each call probes only its own names.

2. The incident is wider than the linked issue

Pulling every sandbox:docker leg from the e2e workflow between 2026-09-16 and 2026-09-20 and checking each failure's log: four legs died of this exact EACCES signature on 2026-09-16, across two hosts — hk1-24 00:27Z, hk2-29 04:26Z, hk2-21 04:39Z, hk2-2 07:45Z (the one #12006 tracks). Every other failure in the window was a different cause.

From 2026-09-17 04:11Z onward the same hosts run the leg green, so the poisoned state ended within about 21 hours. Whether a human cleared it or something else did is not visible from the logs — worth noting because the resolver header asserts "The state does not heal itself: clearing it needs a human on the host," and production neither confirms nor refutes that.

3. On a healthy host the change is not quite byte-for-byte

With no sibling leg running, every recorded stream is identical between the arms except one added stdout line — same docker argv, same locks, same exit codes. But with a sibling leg live, the arms diverge:

The PR moves docker image prune --force --filter until=24h out from under the daemon lock, so it now runs while a sibling leg is mid-test. This is defensible — dangling images are untagged and unreferenced, the age gate is 24h, and the host's own root timer already prunes them without the lock (qwen-docker-cleanup.sh:44) — but the description's "a healthy host is byte-for-byte the old behavior" is not exact, and the same sentence appears in the Chinese section ("健康主机与旧行为逐字节一致").

4. The standing Critical (R7-1) — confirmed, and it is not merely theoretical

Driving the real qwen-docker-cleanup.sh as root against a live leg:

• Healthy host: the leg holds the shared daemon lock → timer prints skipped: sandbox daemon lock busy, labelled prune never runs.
• Poisoned host, PR arm: the leg is in $RUNNER_TEMP, the timer still resolves the shared path, is not skipped by the poison file (:53 only skips when the lock is absent), takes it uncontended as root, and runs the labelled prune against a daemon with a live leg's docker work in flight.

Against real Docker: an image the leg has just accepted via docker image inspect survives the timer's real command at until=24h (negative control, seconds old) and is deleted by the identical command once the threshold puts it past the gate (positive control — threshold shifted rather than waiting 24h), after which docker run fails No such image. R7-1's chain is real end to end.

Where R7-1's premise is only half-supported. It rests on the poison being a root-owned lock file inside a runner-owned directory, which the runner can rm -f with no sudo. Both shapes were built:

And the two shapes are indistinguishable in production: the heal warning, the leg's line 46 error and the prune step's line 2 error are byte-identical between them. So #12006's log cannot tell us which shape hk2-2 had, and R7-1's repair covers one of the two while this PR's fallback covers both.

R7-1's proposed repair was implemented and measured (narrow rm -f of only the probed-unwritable names, re-test, fall back on failure):

It works, it does not weaken the unrepairable case, and it costs 3 existing cases that currently assert "unwritable lock file → fallback" and would need re-pointing at the unrepairable shape. That is a real follow-up, not a reason to hold this PR: on the shapes it cannot repair, the fallback is still the only thing standing between the host and a dead leg.

5. The other open findings

• R5-1 (open) — confirmed. On a poisoned host the prune step emits ::warning::… using job-private lock dir … on stderr while its stdout says Docker cleanup skipped and it opens no lock at all. Two signals, contradicting each other, in the same step.
• R5-2 (open) — confirmed by mutation. Deleting ci_lock_dir='' from the inline fallback's else passes all 56 tests, and on a real host flips the message from cannot create a writable <dir>; … needs a human to Docker cleanup skipped because the shared daemon is active — a cause no probe verified. The branch itself behaves correctly as shipped (verified in all three resolver-absent worlds); only the coverage is missing.
• R9-1 — confirmed. When even the fallback dir cannot be created, the resolver's ::error:: still reaches the annotation list while the step recovers to rc=0.
• R9-2 — confirmed, precisely. Deleting the unconditional dangling prune is killed by 2 cases, both on the poisoned path; the healthy-path cases do not pin it.
• R9-3 — confirmed. The two expect(output).not.toMatch(/prune/) assertions cannot fail: none of the resolver's six output templates contains the word.
• R9-4 — confirmed. The permanently-disabled labelled prune reaches no annotation and no run-page summary; it exists only as one stdout line.

Mutation coverage of what the PR actually protects is otherwise strong — 7 of 8 mutations killed, including every resolver-core one (3–9 cases each).

6. Review gaps this closes

The last review disclosed four gaps. Three are now closed:

• macOS lane: resolve-ci-lock-dir.test.js + e2e-workflow.test.js = 56/56 on Darwin (bash 5.3.15), and 18/18 under Apple's own bash 3.2.57 (/bin/bash, not a GNU 3.2 container).
• shellcheck (repo's exact invocation, pinned 0.11.0): the new script produces one SC2292 style note, the same class the existing run-e2e-tests.sh already carries ~30 of. Nothing new.
• yamllint (pinned 1.35.1, --format github): clean on both arms. The PR lists this as unvalidated.
• actionlint (pinned 1.7.12): clean on both arms with the repo's flags (-shellcheck= disables the embedded-shell pass). Note for accuracy: with default flags the PR arm reports SC1007 on the intentional GITHUB_STEP_SUMMARY= bash … prefix assignment while main is silent — a false positive that the repo's own gate never sees, but "actionlint parses the file cleanly" is true only under the repo's flags.

Recommendation

Merge. The change fixes a failure that is reproducible, recently recurrent across two pool hosts, and fatal to the leg before a single test runs; on a healthy host it costs one log line and one prune that the host's own timer already performs unlocked. The standing Critical is accurate about the cost on a poisoned host, but the alternative on such a host is a leg that cannot run at all.

Two follow-ups worth filing rather than blocking on:

1. R7-1's narrow repair (measured above): it converts a permanent degradation into self-healing for the shape Main CI failed: E2E Tests on aff26a8f36df #12006's triage describes, at the price of re-pointing 3 cases.
2. R5-1 / R9-4 diagnostics: on a poisoned host the operator currently gets a warning naming a lock the step never opened, and no annotation at all for the labelled prune being permanently off.

Two corrections to make in the description before merge: the "byte-for-byte" sentence (§3, both languages), and Fixes #12006 — that issue was closed on 2026-09-18 as superseded by #11991, which is where this belongs.

Autofix round — PR #12016 (issue #12006)

Growth audit (required this round)

Verdict: sound — recorded in growth-audit.json before any edit.

• KISS: pass. Four structurally simpler shapes were considered and each fails the PR's goal: no resolver (that is the Main CI failed: E2E Tests on aff26a8f36df #12006 bug itself), unconditional job-private locks (forfeits coordination on every run, healthy hosts included), tolerating lock-open failure (loses the prune exclusion — the exact timer-vs-live-daemon chain the maintainer reproduced), and the current probe+fallback (minimal coordination-preserving shape). Each accumulated piece is load-bearing for a test-pinned behavior; the test-side overage (410/400) is the bash-driven witness matrix whose gaps were themselves rounds 5–9 findings (R5-2, R9-2, R9-3).
• Minimal change: pass. All six files trace to Main CI failed: E2E Tests on aff26a8f36df #12006 or an accepted round finding; no untraceable hunks.
• This round's work is the standing Critical itself; solving it is primary. The repair re-points three existing cases and adds two, keeping growth minimal.

Feedback dispositions

R7-1 (Critical) — rc:4046529395, rc:4049746075, rc:4054490664; standing in reviews rv:5247538768, rv:5251440468, rv:5257402698 — implemented

Claim: the unconditional veto abandons the shared lock dir when a named lock file is unwritable, but in the #12006 shape (root-owned lock file inside a runner-writable dir) the runner can rm -f the poison without sudo, so the job-private fallback trades away cross-job coordination permanently when a repair was possible.

Reproduced on the pre-round code before implementing (probe, this runner, non-root): shared dir writable + docker-sandbox-daemon.lock at 0400 → resolver printed the job-private fallback with ::warning::; a sudo-less rm -f of the same file succeeded; re-running the resolver then printed the shared dir. The claim held exactly as stated.

Fix (.github/scripts/resolve-ci-lock-dir.sh): the veto loop now unlinks only the caller-named files the probe found unwritable (rm -f --, never a glob, never a writable file), re-tests, and falls back only when the lock name still exists and is still unwritable. The header comment's "does not heal itself" premise was corrected to distinguish the repairable shape (root-owned file in a runner-writable dir) from the residual one (unwritable dir, un-unlinkable name), which still needs a human. The resolver's CLI shape, stdout contract, and silent healthy path are unchanged, so the byte-pinned call sites in e2e-workflow.test.js and the daemon-lock path hardcoded by qwen-docker-cleanup.sh:19 and run-release-docker-integration.sh:32 are untouched — the repair is in place, never a relocation.

Tests (scripts/tests/resolve-ci-lock-dir.test.js):

• New resolver case: writable shared dir + daemon lock at 0400 → resolves to the shared dir, empty stderr, poison unlinked, a fresh lock opens in its place. Red on pre-round code (pre-round behavior = unconditional fallback).
• New leg case: same fixture driven through the real run-e2e-tests.sh → leg green, daemon lock recreated on the shared path, no job-private fallback. Red on pre-round code.
• Three existing cases re-pointed from the repairable shape (0400 file in a writable dir) to an unrepairable one: a directory squatting on the lock name at 0500. This is the only single-uid fixture where rm -f fails inside a writable directory (EISDIR), standing in for any unlink failure (EROFS, foreign-owned name in a sticky dir). I deliberately did not use the suggested chmodSync(shared, 0o555) shape for these: an unwritable directory vetoes at the dir check before the lock loop runs, so it never reaches the repair branch and would leave the failed-repair re-test unwitnessed. All original assertions in the three cases were kept (fallback, warning naming the offender, leg green, daemon/build separation); each gained a "poison left untouched" assertion.
• Narrowness pins added to the two foreign-lock cases: a lock the caller never named is neither repaired nor removed.

Mutation probes (both run, both killed):

• Drop the repair (restore the unconditional return 1 — i.e. pre-round behavior): the two new repair cases fail, 18 others pass.
• Drop the post-unlink re-test (trust rm unconditionally): all three re-pointed squat cases fail (the leg cases die at exec 9> on the surviving directory), 17 others pass.
• (An earlier malformed first mutation that broke the script's syntax failed 15 cases including healthy-path ones; it was discarded and re-applied correctly — only the two valid mutations above are reported as evidence.)

Maintainer verification comment (ic:5747435862, @wenshao)

• Follow-up pre-release: fix ci #1 — R7-1's narrow repair: implemented in this round rather than deferred, since the loop's three CHANGES_REQUESTED reviews all stand on it and the maintainer's own measurement confirmed the repair works and does not weaken the unrepairable case.
• Follow-up Where is the config saved? #2 — R5-1/R9-4 operator-signal improvements: remains deferred; both are Suggestion-level and this round is Critical-only under the growth brake.
• Two PR-description corrections (the "byte-for-byte" sentence in both languages, and retargeting Fixes #12006 to the open Deferred review findings from PR #11974: fix(ci): gate the Linux E2E legs on a disk floor (#11973) #11991): these need a PR-body edit, which this bot cannot perform (no GitHub writes in this mode). Flagging here for the maintainer to apply.

Deferred non-Critical section

Not work — audit record under critical-only mode; no code, thread, or reply actions taken on those items.

Verification

• npm run build — passed (run as the resumable per-workspace equivalent of scripts/build.js, same dependency order: npm run generate + all 27 workspace build steps + generate-settings-schema; this harness caps foreground commands at 120s and reaps detached processes, so the monorepo build was chunked with per-step markers; every chunk exited 0; the sandbox-image tail is a no-op without BUILD_SANDBOX).
• npm run typecheck — passed (80s, exit 0).
• npm run lint — passed (chunked by top-level directory: packages/core, packages/cli, packages/channels, remaining packages, scripts, integrations, integration-tests; every chunk exited 0; neither changed file is in eslint's --ext .ts,.tsx scope).
• npx prettier --experimental-cli --check on both changed files — passed.
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/resolve-ci-lock-dir.test.js scripts/tests/e2e-workflow.test.js — 58 passed (20 + 38; resolver suite grew 18 → 20).
• Full scripts/tests suite — passed via --shard=1/8..8/8 plus the three slow files run individually (install-script 113 passed/16 skipped, acp-serve-boundary-guard 8 passed, qwen-autofix-workflow 338 passed). One failure in scripts/tests/verify-capture.test.js ("preserves colour and bold independently") was reproduced on the unmodified tree (git stash → same failure → git stash pop): pre-existing, environment-related (ANSI rendering), unrelated to this change.
• Mutation probes — see the R7-1 section above; both mutations killed, suite green after restore.
• shellcheck — not installed in this environment (the maintainer's pinned 0.11.0 run found only the pre-existing SC2292 style class; this change adds no new shell constructs beyond rm -f -- … || true and an [[ -e && ! -w ]] re-test).

Notes

• No test weakening: no file deleted, no test disabled, no assertion removed; enabled resolver-suite tests went 18 → 20 and the three re-pointed cases kept every assertion they had (each gained one). No test-weakening.json required.
• No comment-replies.json: every inline finding this round (the three R7-1 threads) is resolved in code.
• No base-conflict resolution requested (--conflict false); no merge performed.

Deferred non-Critical feedback

Critical-only mode is active: the PR's diff grew src 33 / test 410 net lines beyond this counting window's baseline (budgets: 400/400). The workflow excluded the non-Critical feedback below from this round's actionable sections; the items remain open for human follow-up. Maintainer feedback continues to flow unaffected during a growth-only engagement (the per-author batch budget applies only after 5 change-producing rounds).

Autofix round — PR #12016 (issue #12006): no code change this round

Why no change

Every actionable finding is already resolved in code at the current head (1effcfbedc), and the maintainer has explicitly steered this PR to merge with the remaining items filed as follow-ups.

• The one standing Critical (R7-1) was fixed by e2993f3e76 ("repair an unwritable CI lock file in place before falling back"), which landed after the latest review (round 9, reviewed 1cf3bc95). The resolver now unlinks only the caller-named lock files its probe found unwritable, re-tests, and falls back to the job-private dir only when the repair fails — exactly the narrow repair the maintainer independently implemented and measured. I re-verified it at the current head; see Verification below.
• The maintainer's verification (@wenshao, issue comment 5747435862) recommends merge. Follow-up pre-release: fix ci #1 (R7-1's narrow repair) is done in e2993f3e76; follow-up Where is the config saved? #2 (R5-1/R9-4 diagnostics) and the remaining Suggestions are explicitly "worth filing rather than blocking on". This PR has been through ~9 review rounds, so per the review-rounds policy it now lands Criticals only and defers Suggestions.
• CI is green at this exact head — all required checks SUCCESS; macOS/Windows lanes are trigger-gated off pull requests by design.

Resolved this round (re-verified, fixed by an earlier commit)

• R7-1 (rc:4046529395, rc:4049746075, rc:4054490664): repair-in-place confirmed working at 1effcfbedc — see Verification. Threads listed in resolved-comments.txt.

Deferred to the follow-up queue (recorded, threads left open with a reply)

Per the maintainer's recommendation and the convergence posture, no Suggestion-level item is implemented in this PR:

• rc:4036007801 (R5-1) and R9-4 — the maintainer's follow-up Where is the config saved? #2 (operator diagnostics on a poisoned host).
• rc:4036007811 (R5-2) — coverage of the inline fallback's else arm (maintainer confirmed the gap by mutation).
• rc:4025497792 (R1-2 remainder) — resolver adoption at the release lane / sdk-java.yml and a host-shared fallback tier: outside this PR's footprint.
• rc:4031664803 (R4-1/R7-2), rc:4031664817 (R4-2), rc:4031664822 (R4-3) — diagnostics accuracy / coverage, same follow-up cluster.
• R9-1, R9-2, R9-3 (round-9 deferrals, review 5257402698) — maintainer-confirmed diagnostics/coverage gaps.

All recorded in deferred-findings.json; the inline threads have bilingual replies in comment-replies.json.

Needs the maintainer (this bot has no GitHub writes)

Two PR-description corrections from the verification comment remain open — they require editing the PR body, which only a human or the PR workflow can do:

1. The "byte-for-byte" sentence (§3 of the verification, both languages): with a sibling leg live, the PR runs the dangling prune that main skips.
2. Fixes #12006 → retarget to Deferred review findings from PR #11974: fix(ci): gate the Linux E2E legs on a disk floor (#11973) #11991 (issue Main CI failed: E2E Tests on aff26a8f36df #12006 was closed on 2026-09-18 as superseded).

Note on the two triage-verify failures

Issue comments 5747219213 and 5747495869 report the sandboxed-verification harness failing at pnpm install before any verification started. This is not attributable to the PR's content: the diff touches no dependency manifest or lockfile (only .github/scripts/*.sh, .github/workflows/e2e.yml, and scripts/tests/*), a clean install was already performed on this runner before this round, the focused suites execute green locally, and all PR CI checks pass at this head.

Verification

• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/resolve-ci-lock-dir.test.js scripts/tests/e2e-workflow.test.js — 58 passed (20 + 38), 0 failed.
• Behavioral probe of R7-1's fix at this head (real bash, non-root, temp HOME): (a) writable shared dir + docker-sandbox-daemon.lock at 0400 → resolver prints the shared dir, rc=0, poison unlinked; (b) a directory squatting on the lock name at 0500 → resolver falls back to the job-private dir with ::warning:: naming the offender, rc=0, poison untouched.
• git status — clean; HEAD 1effcfbedc (matches origin). All 14 checks at this SHA: SUCCESS/SKIPPED, none failing.

No commit was created; the working tree is unchanged.

With a live holder mirroring the root qwen-docker-cleanup timer (exec 8>> + flock --exclusive + chmod 0400) on docker-sandbox-daemon.lock, the pre-fix resolver: exited 0 certifying the shared dir, printed no ::warning::, and unlinked the held inode (ino_after=GONE). Probe script and output are reproducible from this round's log.

Fix (.github/scripts/resolve-ci-lock-dir.sh): a new lock_held probe runs before any rm -f; a lock that cannot be proved unheld is refused, and the resolver falls back to the job-private dir with the cause named (... is not writable and is locked by a live process). Two probes, because each sees a shape the other cannot:

1. a read-only open plus a non-blocking exclusive flock — refused exactly when a holder sits on the inode, and < can never truncate a held one (the >>-never-> constraint is honoured by never opening for write at all);
2. /proc/locks (read as the job uid, no access to the file needed) for the finding's exact production shape — the root-owned 0400 daemon lock that cannot even be opened. Where neither probe exists (macOS has neither flock(1) nor /proc/locks) the probe reports not-held, leaving those lanes on the previous behaviour.

Also per the finding: the successful heal now emits a ::warning:: on stderr naming the file it unlinked (stdout stays the single-path payload both callers capture with $(...)), and the stale comment that claimed the re-test covers a root process holding the old inode was corrected (the re-test never saw that case — after a successful rm -f, -e is false). The daemon lock is repaired in place or refused — never relocated.

Tests (scripts/tests/resolve-ci-lock-dir.test.js):

• New case refuses to unlink a lock a live process holds: a holder takes flock -x on the shared daemon lock and sleeps; asserts the resolver prints the job-private fallback with a ::warning::, statSync(daemonLock).ino is unchanged, and a contender flock --nonblock -x fails while the holder sleeps. Skips only where the fixture cannot exist (root, or no flock(1) — macOS).
• Updated repairs an unwritable lock file in place...: the heal now pins the ::warning:: naming the file instead of pinning an empty stderr. An unheld foreign-owned 0400 file is still unlinked, as the finding requires.

Mutation probes (guard deleted → test red → restored → green):

• lock_held guard removed → refuses to unlink a lock a live process holds FAILED (×), 20 others green; restored → 21/21 green.
• Heal ::warning:: removed → repairs an unwritable lock file in place... FAILED (×); restored → 21/21 green.

Both changed tests therefore fail on the pre-round code and pass on the round's code.

Not addressed (out of scope this round)

• The four R10-* items and the eight re-deferred Suggestions were explicitly listed as "recorded, not requested in this round" / already deferred in rounds 5–9. Left untouched.
• verify-capture.test.js > preserves colour and bold independently fails in the full scripts run. It fails identically with this round's two files restored to HEAD (verified: snapshot diff → git checkout -- → rerun → same failure → re-applied), so it is a pre-existing, environment-caused failure (bold font rendering in this container), not a regression from this round. It lives far outside this PR's footprint.

Verification

• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/resolve-ci-lock-dir.test.js — 21 passed (also green in the full-suite run: ✓ ... (21 tests))
• npm run test:scripts — 2566 passed, 19 skipped, 1 failed; the single failure is the pre-existing verify-capture bold-font case proven above to reproduce at base content
• npm run build — passed (exit 0)
• npm run typecheck — passed (exit 0)
• npm run lint — passed (exit 0)
• Live reproduction probe (holder + real resolver, before/after) — before: held lock unlinked, shared dir certified, stderr silent; after: job-private fallback with ::warning::, inode unchanged, contender flock refused
• Mutation probes — both new witnesses go red when their guard is removed (see above)
• Integration tests via npm run bundle — not run: the touched behavior (CI workflow shell scripts) is never exercised through the bundled CLI; the bash-driven scripts suite above is its harness
• Note: /proc/locks is blind in this sandbox (0 entries while a lock is verifiably held), so the /proc/locks branch was verified by inspection here; the flock-probe branch — the one the new test drives — was executed for real. On real-kernel CI runners /proc/locks covers the root-owned 0400 case from the finding.

Round summary — PR #12016 (issue #12006)

Commit: 10540b602b fix(ci): correct the /proc/locks witness and vet lock openability in the resolver (#12006)

Both Critical findings from round 11 were reproduced and fixed at the root, each with the test coverage the finding asked for. No feedback was declined, deferred, or escalated. No merge conflicts (--conflict false).

[rc:4058048832] Critical R7-1 — /proc/locks witness keyed on the PID field — RESOLVED

Reproduced. A /proc/locks line is <id>: FLOCK ADVISORY WRITE <pid> <major>:<minor>:<inode> <start> <end>: $5 is the holder's PID, $6 the device:inode triple (verified against /proc/self/fdinfo/8 on a live flock). The shipped awk split $5, so a[3] was always empty and the witness could never report "held" — inert exactly on the unreadable root-owned-lock path (flock probe exits 66) that the guard exists for. End-to-end probe of the shipped script against a real live holder on a 0000 lock (flock probe genuinely exiting 66, witness line fed through an awk shim because this sandbox masks /proc/locks): the resolver certified the shared dir, printed ::warning::unlinked stale unwritable lock file …, and unlinked the live-held inode (stat after: inode gone).

Fix. lock_held now builds major:minor:inode from stat -c %D/%i (hex arithmetic in bash, not awk — strtonum is gawk-only) and matches $6 against it, comparing the device with the inode so an inode-only match cannot name a phantom holder on another filesystem. The daemon lock path, the resolver's CLI shape, and the heal's >>-only probing are unchanged, per the finding's constraints. Same probe after the fix: job-private fallback, is not writable and is locked by a live process on stderr, held inode preserved.

Tests. Added beside refuses to unlink a lock a live process holds in scripts/tests/resolve-ci-lock-dir.test.js:

• refuses to unlink an unreadable lock a live process holds — the requested 0000 case (identical exec 8>> + exclusive flock holder, gated isRoot || !hasFlock || !hasProcLocksWitness), asserting the job-private fallback on stdout, the held-warning on stderr, the inode unchanged, and a contender's flock --nonblock --exclusive still failing. One deliberate deviation from the requested assertions: the contender probe runs after restoring the mode to 0600, because a 0000 file refuses every open with EACCES and the probe would never reach the flock it is meant to measure. The gate also carries one deliberate addition: hasProcLocksWitness (a hold-a-flock-and-look capability probe) replaces a bare existsSync('/proc/locks'), because sandboxes can present /proc/locks as an empty masked file — as this runner does — where the witness environment genuinely cannot exist and the case would assert a veto nothing can produce. On normal Linux CI (and the pool runners the script targets) the probe passes and the case runs.
• heals an unreadable lock no live process holds — the requested negative sibling (unheld 0000 lock must still be healed), which is what catches an always-held witness mutant.

Mutation probes.

• Always-held witness mutant (a return 0 planted after the awk): the negative sibling goes RED (Tests 1 failed | 24 skipped), restored byte-identical after.
• $6→$5 revert: the committed positive case capability-skips on this masked-/proc/locks sandbox, so the revert was instead driven end-to-end through the real script with the awk shim: the $5 mutant unlinks the live-held 0000 lock and certifies the shared dir (inode gone), while the fixed script vetoes and preserves it — the exact properties the committed test asserts wherever /proc/locks works, where it goes red on the revert.

[rc:4058048841] Critical R11-1 — mode-bit gate where callers then open() — RESOLVED

Reproduced. The two requested prune-step cases were written first and run against the pre-round code: both RED. With a runner-owned 0755 directory at the daemon-lock name the step printed Docker cleanup skipped because the shared daemon is active (the EISDIR open failure swallowed by the elif condition under bash -e, misreported as a live daemon); with a dangling symlink whose target sits inside the same writable directory the labelled docker image prune --all --force ran behind a lock that excludes nothing.

Fix (one structural close, not per-entrance patches). In resolve-ci-lock-dir.sh's probe loop, before the mode-bit branch: refuse any name that exists (or is a dangling symlink — -e follows links, so -L sees it) but is not a regular file; after the existing heal: vet the very open the caller makes next with (exec 9>>…) — append mode so the probe can never truncate an inode a live process flocks — gated on the name still existing so a just-healed name is not re-created ahead of the caller's own open (keeps the pinned existsSync(...) === false heal witness green). The regular-file vet is what keeps that open bounded (a FIFO would hang it). In the e2e.yml prune step the exec 9> moved out of the elif condition into its own if ! exec … arm with an explicit cannot open … for writing skip line, so bash -e can no longer fold an open failure into the shared daemon is active message; the resolver-fallback skip reason now names the daemon lock path. The byte-for-byte pin in scripts/tests/e2e-workflow.test.js was updated to the new shape (if ! exec 9>… + elif flock --nonblock 9), assertion count unchanged (one pin became two). e2e.yml stays within its size ratchet (35969 B vs 33227 B baseline + 4096 B allowance).

Tests. Added under describe('prune step daemon lock discipline'), both driving runPruneStep(world, { withResolver: true }) and both red pre-round:

• skips the labelled prune when a directory squats on the daemon lock name (default 0755, not the 0500 the existing cases use), and
• skips the labelled prune when a dangling symlink squats on the daemon lock name (target inside the same writable directory),

each asserting no shared daemon is active, a skip line naming docker-sandbox-daemon.lock, no image prune --all in the docker log, and the unconditional dangling prune still running; the symlink case also pins that the squatter is refused, never repaired away.

Mutation probe. Reverting the resolver's vetting to the bare [[ -e && ! -w ]] gate turns the symlink case RED. The directory case stays green under that single revert because the step-side open arm — the finding's other requested change — independently catches EISDIR with a truthful skip line; against the fully pre-round code both cases are red (verified directly).

Notes for reviewers

• The six [probe] items in the review's deferred section were recorded there by the reviewer as non-blocking for this round and were not worked. One of them (the inode-only phantom-holder gap) is closed as a load-bearing part of the R7-1 fix; the rest (the lock_held check-then-act race, the /proc/locks-branch coverage, the banner's permanent-human framing, the leg-side labelled prune, the strict-prefix pin) remain deferred as recorded.
• No CI machinery outside this PR's own footprint was touched; all four changed files were already in the PR diff. No test was deleted, disabled, or weakened — one pin string was updated to the new prune-step shape and its assertion count grew.

Verification

• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/resolve-ci-lock-dir.test.js — 24 passed, 1 skipped (the 0000 live-holder case capability-skips on this sandbox's masked /proc/locks; runs on normal Linux CI)
• npx vitest run --config ./scripts/tests/vitest.config.ts scripts/tests/e2e-workflow.test.js — 38 passed
• npx vitest run … scripts/tests/workflow-size.test.js scripts/tests/no-ak-integration-ci.test.js (same config, with the two files above) — 4 files, 290 passed, 1 skipped
• New prune-step cases against the pre-round code — both failed as reproduced defects (red-first)
• Mutation probes — always-held witness: negative sibling red; resolver-vetting revert: symlink case red; $5 revert via awk shim against a real live holder: live-held inode unlinked by the mutant, preserved by the fix (details above)
• bash -n .github/scripts/resolve-ci-lock-dir.sh — syntax ok
• npx prettier --check on all four changed files — clean (after --write on the test file; suites re-run green after formatting)
• npm run typecheck — passed
• npm run build — passed; run as the exact per-package sequence of scripts/build.js (generate → browser-use → core → channels → audio-capture → node-repl → acp-bridge → sdk-typescript → web-shell → web-templates → cli → settings-schema → qwen-live → vscode-ide-companion → chrome-extension → external-context ×2), every step rc=0, because this runner kills any single command at 120s and the monolithic invocation exceeds it; the opt-in sandbox image build (BUILD_SANDBOX=1) was not run, and generate-settings-schema produced no diff
• npm run lint (eslint . --ext .ts,.tsx + eslint integration-tests) — passed; run in chunks under the same 120s limit (scripts + integration-tests, packages/cli, packages/core, all remaining packages/integrations, root-level files), every chunk rc=0

Closing this — the linked issue #12006 was closed as not planned in favor of #11991, which prescribes a different remedy for the lock-dir problem. This diff also predates the pnpm migration (#11859) and no longer applies to the current e2e.yml. If the unwritable sandbox lock dir recurs on self-hosted runners, the #11991 direction is the one to implement.
