# Automated repo hygiene — single source of truth.
# CI (.github/workflows/hygiene.yml) runs `pre-commit run --all-files`, so these
# are enforced on every push whether or not you ran `pre-commit install` locally.
# Optional local install:  pipx install pre-commit && pre-commit install

  # Local: companion/version drift linter (self-audit 2026-06-07/FF-004) — automates the
  # MANIFEST.md drift check. Whole-repo consistency check, so it always runs regardless of
  # which files changed. FF ids are per-cycle, hence the date qualifiers (MANIFEST.md).
