Summary

Replaces tag/branch references in workflow files with commit SHAs reachable at or before 2026-04-28T00:00:00Z.

Why

Mitigates the supply-chain risk of mutable tag/branch references in third-party GitHub Actions following the 2026-04-28 incident. Tag references can be force-updated by upstream maintainers; SHAs are immutable.

How

  • Original version is preserved as a trailing comment (e.g. uses: foo/bar@<sha> # v1) so Renovate / Dependabot can still detect upstream upgrades.
  • SHAs were pre-resolved and verified by the upstream pipeline (resolve_sha.py + verify_sha.py).

Test plan

  • CI green
  • Workflow files diff-reviewed for unintended changes

Pin third-party and internal action references to commit SHAs reachable
at or before 2026-04-28T00:00:00Z, replacing tag/branch references.
