Summary

Estate-wide incident: github/codeql-action v4.38.1 fails GitHub workflow startup on every repo that took it — CodeQL/Hypatia runs die with startup_failure, zero jobs dispatched, no error text in any API surface. The evidence chain (full detail: nexia-list#100):

repo ref status
nexia-list @v4.38.1 tag (via dependabot #94) 🔴 startup_failure → fixed by rollback #100 (merged)
hypatia @1c5b675 (4.38.1 SHA) 🔴
vexometer @v4.38.1 🔴 (since Sep-21)
rsr-template-repo @1c5b675 🔴
affinescript / boj-server / deed-ecosystem ≤ v4.38.0 ✅ green

The v4.38.1 tag exists (peels to 1c5b675) and byte-identical workflow content runs under a fresh path — so the failure is the version value itself at GitHub's start-validation layer, not content, permissions (probes with security-events start fine), or the default-setup conflict.

Changes here

  • codeql-reusable.yml, hypatia-scan-reusable.yml: codeql-action/* re-pinned 1c5b675 (v4.38.1) → b96794f0 (v4.38.0 commit; wrong # v3 comments corrected to # v4.38.0).
  • actions.lock: re-keyed to the v4.38.0 SHA entries (dependabot bumped the reusable pins without regenerating the lock).
  • dependabot.yml: full hold on github/codeql-action — scoped versions: ignores do NOT hold for this bot path (nexia-list#101 re-raised the bump in SHA form within an hour, copying the inline warning comment verbatim while swapping the SHA).

Follow-ups

Consumer rollbacks shipped in the same batch: nexia-list (merged ✅), hypatia, vexometer, rsr-template-repo, metadatastician/burble (each with the same dependabot hold). Reconsider the hold when upstream clears v4.38.1 or a newer release verifies green on one canary repo.

v4.38.1 (tag AND commit SHA 1c5b675) fails GitHub workflow-startup
validation estate-wide: codeql/hypatia runs die with startup_failure,
zero jobs, no API error text. Full investigation: nexia-list#100.
Rollback to the v4.38.0 commit b96794f015dfd88f77b49b1c93e0fa7110f94c63
(green on deed-ecosystem; satisfies repo SHA-pin policy). actions.lock
re-keyed where present; dependabot held unconditionally (versions-scoped
ignores were bypassed in SHA form - nexia-list#101).

Canonical fix: hyperpolymath/standards#973.

📝 Summary

Summary by CodeRabbit

  • Bug Fixes

    • Restored reliable CodeQL workflow startup by pinning the analysis actions to a validated version.
  • Chores

    • Prevented automated dependency updates from proposing the currently blocked CodeQL action version.
    • Documented the temporary version hold and the conditions for resuming updates.

Walkthrough

The change pins CodeQL workflow actions to the v4.38.0 commit and prevents Dependabot from proposing updates for github/codeql-action.

A rabbit checks the workflow gate,
CodeQL rests at version thirty-eight-oh,
Dependabot pauses its update quest,
Two pinned steps keep checks at rest,
Until a validated release is best.

Regenerate the workflow lockfile for the new CodeQL pin.

.github/workflows/actions.lock records github/codeql-action@v4.37.9, while both CodeQL steps use b96794f015dfd88f77b49b1c93e0fa7110f94c63 (v4.38.0). Run gh actions-lock and commit the generated lockfile update.
