fix(ci): resync actions.lock and add a lock-sync recurrence gate - #286
Merged
Merged
Conversation
GitHub refuses a run at startup, creating zero jobs, when a workflow carries a `uses:` ref that the lockfile does not record under that workflow's own path. It matches by LITERAL STRING; `gh actions-lock` matches by resolved commit, so a lock entry naming a tag that dereferences to the pinned SHA passes the tool and still kills the run. Regenerate the lock, make it transitively closed, and add a lock-sync gate carrying no `uses:` of its own so it cannot be disabled by the desync it detects. No workflow YAML is modified.

In `@scripts/check-lock-sync.sh`:
- Around line 73-77: Build WORKFLOWS directly from the nullglob-expanded
workflow patterns before checking its length, so no matching files produces an
empty array rather than an empty element. Keep the no-workflow guard effective,
then preserve the existing sort/deduplication step before WORKFLOWS is consumed.
- Line 157: Update the $/ reference handling in the lock-sync validation logic
so valid self-repository paths pass unchanged; only record and fail references
with a trailing `@ref` suffix, and revise the associated failure message to
describe that constraint.

Do not fail workflows that use the $/<path> self-repository syntax.
$/<path> is valid GitHub Actions syntax. It resolves to the same repository at the running commit and needs no lockfile entry. Only a trailing @ref makes the reference invalid.
The current check marks every $/ reference as corruption and fails valid workflows. Check for the invalid suffix instead.
🐛 Suggested fix
- if (raw ~ /^\$\//) { dollar[wf] = dollar[wf] " " raw; next } # known corruption

What this fixes
.github/workflows/actions.lockhad drifted from the workflow YAML. That drift isnot cosmetic: GitHub refuses such a run at startup, creating zero jobs, and
reports only "This run likely failed because of a workflow file issue." Most of a
repository's CI can be silently dead for days without a single red tick, because a
run that never starts posts no check.
Measured across the estate on 2026-09-22: 13 of 37 repositories swept were in
this state.
Why it happened here
GitHub's startup check compares the lockfile ref to the workflow's
uses:ref as aliteral string.
gh actions-lockcompares them by resolved commit. The twodisagree whenever a lock entry names a tag that dereferences to exactly the commit
the YAML pins — the tool prints
All N workflows validand GitHub still kills therun.
Proof, on
hyperpolymath/awesome-nickel/codeql.yml:uses:ad035f4e(09-21)codeql-action/init@v4.38.0codeql-action@v4.38.09d83550d(09-22)codeql-action/init@b96794f0…codeql-action@v4.38.0startup_failure, jobs=0v4.38.0dereferences tob96794f0…— the same commit the YAML pins — and the runstill died. A cross-workflow control at the same heads (
boj-build.yml, lock-matched)was green, so the lock is not globally broken; the failure is scoped to the one
workflow whose entry mismatches.
What changed
.github/workflows/actions.lockregenerated and made transitively closed. A refnamed under
workflows:or inside another record's nesteduses:with no top-leveldependencies:record is a dangling edge and kills the run at startup.below.
gh actions-lockwas run with--no-migrate-local-actions, which prevents itrewriting
uses: ./…intouses: $/…— an invalid form that itself causes startupdeath.
The recurrence gate (the actual defect)
Regenerating alone is a one-week fix: Dependabot rewrites
uses:refs in the YAML on aschedule and cannot touch the lockfile, so the repo re-breaks on the next grouped
bump. This PR therefore also adds:
.github/workflows/lock-sync-gate.yml— fails any PR whose lockfile has drifted.scripts/check-lock-sync.sh— the check itself.The gate deliberately carries no
uses:of its own — it checks out by callinggitin a
run:step instead ofactions/checkout, so it has no lockfile entry to go staleand is structurally immune to the very failure it detects. It also has no
paths:filter, on purpose: a filtered workflow never reports on PRs that miss the filter, which
would deadlock any branch ruleset requiring this check.
The gate hard-fails on desync. It is not
continue-on-errorand not a::warning::,which cannot fail a job.
Note on
gh actions-lock --verify-localThe gate does not call
gh actions-lock --verify-local, which was the originallyproposed mechanism. That tool is measured wrong in both directions: it reports STALE on
job-level reusable-workflow refs it cannot parse (upstream #129 — 5 repos in this sweep
are false reds from exactly that), and it reports valid on the tag-vs-SHA literal
mismatch above.
check-lock-sync.shtests literal-string equality, which is what GitHubactually enforces.
Expected on this PR
Workflows that have not executed since the desync began will run here for the first
time, and some may go red for reasons unrelated to this change. Per the estate stopping
rule each becomes its own issue with acceptance criteria, not a blocker on this PR.
