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

  • Chores
    • Updated the security analysis workflow to a newer CodeQL Action release.
    • Adjusted automated dependency update settings so CodeQL Action updates are no longer proposed automatically.

Walkthrough

The CodeQL workflow now uses v4.38.0 for both CodeQL action steps. Dependabot ignores future updates for github/codeql-action. Existing workflow inputs remain unchanged.
