The CI failure appears to be a permissions issue in the workflow, not related to my PR changes.

The check-readme-only job fails at github.rest.pulls.listFiles() with HttpError: Resource not accessible by integration. It looks like the workflow is missing contents: read permission — it only declares pull-requests: write.

Suggested fix for .github/workflows/check-readme-only.yml:

jobs:
  check-readme-only:
    permissions:
      contents: read        # needed for pulls.listFiles()
      pull-requests: write

Same for the handle-confirmation job which calls listLabelsOnIssue().

My PR only adds one line to README.md.
