📝 Walkthrough

Walkthrough

The validate-workflows.yml CI workflow receives four targeted changes: permissions.contents and permissions.pull-requests are both downgraded from write to read; actions/setup-python is bumped from v5 to v6; actions/upload-artifact is bumped from v4 to v7; and the fallback branch that resolves changed files when the base ref is unavailable is narrowed from scanning all repository YAML to scanning only .github/workflows YAML.

Warning

Review ran into problems

🔥 Problems

Stopped waiting for pipeline failures after 30000ms. One of your pipelines takes longer than our 30000ms fetch window to run, so review may not consider pipeline-failure results for inline comments if any failures occurred after the fetch window. Increase the timeout if you want to wait longer or run a @coderabbit review after the pipeline has finished.
