Pin all third-party GitHub Actions to immutable commit SHAs.
Why
Action tags (like v3, v4, main) can be moved or retagged, which means a future workflow run could execute different code than what we reviewed today. Pinning to SHAs makes the workflow supply chain deterministic and auditable, reducing the risk of action-level compromise or accidental breaking changes. We can still update intentionally by bumping the SHA.
This PR pins all third-party GitHub Actions to immutable commit SHAs across 4 workflow files, improving supply chain security by preventing tag movement. However, the PR also deletes 2 Coana workflow files (coana-analysis.yml and coana-guardrail.yml) which is not mentioned in the PR description.
Key changes:
Pinned actions/checkout@v6 to de0fac2e... (v6.0.2)
Pinned actions/setup-node@v6 to 6044e13b... (v6.2.0)
Pinned denoland/setup-deno@v2 to e95548e5... (v2.0.3)
Pinned oven-sh/setup-bun@v2 to 3d267786... (v2.1.2)
Deleted Coana vulnerability analysis and guardrail workflows
The SHA pinning follows security best practices with clear version comments. The unexpected workflow deletions should be verified and documented in the PR description.
Confidence Score: 3/5
This PR is safe to merge but requires clarification on workflow deletions
The SHA pinning implementation is correct and improves security, but the deletion of two Coana workflows without explanation in the PR description is a documentation concern that should be addressed
Pay close attention to coana-analysis.yml and coana-guardrail.yml - verify these deletions are intentional
