## CI Security Gate — automatic approval blocked

This PR was **not** automatically approved for CI because the security gate failed.

**Possible reasons:**
- The PR touches 50 or more files — only PRs with fewer than 50 changed files are automatically approved
- A changed file is outside the allowed directories (`src/`, `tests/`, `docs/`, `utils/`), has a disallowed extension (only `.py`, `.txt`, `.md` permitted outside `tests/` and `docs/`), or is not `.md`/`.yml` inside `docs/`
- A new high-severity security issue was detected in the changed Python files (Bandit check)

See the [workflow run](https://github.com/huggingface/transformers/actions/runs/27768179053) for the exact violations.

A maintainer can review and manually approve CI if a finding is a false positive.

The docs for this PR live [here](https://moon-ci-docs.huggingface.co/docs/transformers/pr_46565). All of your documentation changes will be reflected on that endpoint. The docs are available until 30 days after the last update.
