The gh api call result is stored without validating that it's valid JSON or that .head.sha is non-empty. If the API call fails and 2>/dev/null suppresses the error, DATA could be empty and head_sha would be set to 'null' (the string), which could cause subtle failures downstream. Consider adding a check.

Pinning the reusable workflow to @main means any future breaking change or malicious commit to that branch will immediately affect this workflow. Consider pinning to a specific SHA or a version tag for supply-chain safety.
