Release checklist

The repository is intentionally frozen on Python 3.12.13, uv 0.11.6, exact Python requirements, immutable container digests, and commit-pinned GitHub Actions. Do not refresh these inputs unless intentionally creating a new maintained release.

1. Update RELEASE_NOTES.md.
2. Run uv run python scripts/bump_version.py X.Y.Z.
3. Run ./scripts/check.sh.
4. Review and commit all version metadata together.
5. Tag the reviewed commit after it is merged.

Use uv run python scripts/bump_version.py --check to verify that all committed version locations agree without changing files.
