Code Review: Update actions/setup-python to v6

Summary

This PR updates actions/setup-python from v5 to v6 in the bump-version workflow. The change is straightforward and follows security best practices by using commit SHA pinning.

✅ Positive Aspects

1. Security Best Practice: Uses full commit SHA (83679a892e2d95755f2dac6acb0bfd1e9ac5d548) with version comment, which protects against tag manipulation attacks
2. Minimal Scope: Only affects one workflow file, reducing blast radius
3. Consistent Versioning: Matches the pattern already used in the workflow (e.g., actions/checkout@v6 on line 18)
4. Low Risk: This is a dependency update for a stable GitHub Action with minimal breaking changes between v5 and v6

🔍 Observations

1. Single Usage: This is the only occurrence of actions/setup-python in the codebase, so no other files need updating
2. Python Version: The workflow uses Python 3.11, which is fully supported by both v5 and v6
3. No Breaking Changes: The v5→v6 update for setup-python is primarily maintenance and Node.js runtime updates (v16→v20), with no breaking API changes affecting this usage

📋 Recommendations

None - This PR is ready to merge. The change is low-risk, follows security best practices, and aligns with the repository's existing patterns.

Verdict

✅ APPROVED - Safe to merge.

PR Review: Update actions/setup-python to v6

Summary

This is a dependency update from Renovate Bot upgrading actions/setup-python from v5 to v6 in the bump-version.yml workflow.

Code Quality ✅

• Clean change: Single line update with pinned commit hash for security
• Follows security best practices: Uses commit SHA alongside version tag
• Consistent with repo patterns: Matches the style used for other actions (e.g., actions/checkout@8e8c483...)

Compatibility ✅

• Python version compatibility: The workflow uses Python 3.11, which is compatible with both v5 and v6
• Project requirements: pyproject.toml specifies requires-python = ">=3.11", so no version conflicts
• Workflow scope: This only affects the version bumping workflow, not the main test suite

Potential Concerns

1. No CI status visible: Unable to verify if CI checks have passed (approval needed for gh pr checks command)
2. Other workflows not updated: The PR only updates bump-version.yml. Other workflows may still use v5:
   • Consider checking if other workflows (test.yml, release.yml, etc.) should also be updated for consistency
   • This can be done in a follow-up PR if Renovate manages them separately

Security ✅

• Commit hash pinning: Good security practice - prevents tag hijacking
• New hash verification: 83679a892e2d95755f2dac6acb0bfd1e9ac5d548 should be verified to match the official v6 release tag

Testing Recommendations

• Run the bump-version workflow manually or wait for it to trigger on the next master merge
• Verify that Python 3.11 installation and uv setup work correctly with v6
• Monitor for any warnings or deprecation notices in workflow logs

Overall Assessment: APPROVE ✅

This is a straightforward, low-risk dependency update that follows the repository's security and coding conventions. The change is limited in scope and unlikely to cause issues.

Recommendation: Merge after verifying CI checks pass.
