  # mypy runs through uv so the resolved dependency tree matches uv.lock and
  # CI exactly. The mirrors-mypy hook installs into an isolated venv whose
  # versions can diverge from uv.lock, which lets test-side errors slip past
  # local pre-commit even though CI catches them. We trade hook-internal
  # caching for src+tests coverage that mirrors CI.
