  # DOCUMENTED LIMITATION (#1339 review): the exact pre-fix #1150 shape --
  # bare dirname in an unguarded helper CALLED FROM the guarded branch.
  # ast-grep has no cross-function reach, so this is deliberately a
  # negative fixture; it exists so a future strengthening flips it to a
  # positive consciously, not accidentally. Review-enforced meanwhile
  # (AGENTS.md defect-shape 2).
