repos:
  # ruff runs from the project's own environment rather than a separately
  # pinned rev. The dev group's ruff floats, and CI resolves it from uv.lock,
  # so an exact `rev:` here is a second version that drifts against it -- and
  # not always harmlessly: ruff 0.16 formats Python inside Markdown and 0.15
  # does not, so `pre-commit run --all-files` passed while `ruff format
  # --check` failed in CI on the same README, across five repos. A hook that
  # green-lights what CI rejects is worse than no hook.
