Why

Pinning actions to full commit SHAs prevents future tag or branch retargeting from changing workflow behavior without review.

Reviewer notes

  • Original refs are preserved in inline comments when possible.
  • Pin comments use the Dependabot-compatible original-ref style.
  • Branch refs were allowed and pinned to their current HEAD; review mutable-branch pins carefully.
  • No minimum action age was enforced for this run.

Dependabot

  • Added .github/dependabot.yml enabling weekly github-actions updates with a 7-day cooldown (cooldown: default-days: 7).
  • The cooldown delays applying a newly published action release for 7 days, reducing exposure to a compromised or broken release while keeping you SHA-pinned.
