The comment on line 29 accurately describes the purpose of this step. However, it could be more specific about the scenarios this handles. Consider expanding it to:

"Check out the actual PR branch so we can push changes back if needed. This uses 'gh pr checkout' which properly handles both same-repo and fork PRs, unlike the previous 'ref: github.head_ref' approach which fails for fork PRs."

This provides better context for future maintainers about why this approach was chosen.

The gh pr checkout command requires the GitHub CLI to be available in the runner. While ubuntu-latest runners typically have gh pre-installed, this dependency is implicit and could break if the runner image changes. Consider adding a comment documenting this requirement, or add an explicit step to ensure gh is available (e.g., using actions/github-cli-setup or verifying with gh --version).
