Findings

• ⏰ STALE: Open for 101 days — investigate why it has not yet merged. This may indicate failing CI, an unresolved conflict, a dependency issue, or missed assignment.
• Tooling update only (GitHub Actions). No runtime Python dependency changes.

Recommended Validation

• Re-trigger CI to verify that the SHA-pinned GitHub Actions run successfully.
