Thanks for your first PR on sql-sop! Quick checks:

• pytest -q and ruff check . pass locally
• Every new rule has both a "fires on bad SQL" test AND a
  "does NOT fire on safe SQL" test
• Rule IDs (E001, W001, …) are public API — don't renumber
  or rename existing ones without the deprecation process in
  GOVERNANCE.md
• CHANGELOG.md [Unreleased] entry for any user-facing change
