Investigating CI Failures

When a PR has failing CI checks, prefer the investigation script. If it is unavailable or incompatible with the execution environment, use the read-only manual fallback below.

The script reads from GitHub and downloads artifacts locally. It does not modify remote resources. Downloads use the system temporary directory; check that this destination is suitable for the execution environment.

Step 1: Run the Script

# Investigate a specific PR by number
python3 repo_support/investigate_ci.py 2946

# Or by run ID directly
python3 repo_support/investigate_ci.py 23017249697
