# DB Migration Check

> Verify that SQLAlchemy model changes have corresponding Alembic migration files. Trigger when any file under models/*.py or models/**/*.py is modified — checks git diff for model changes and confirms matching alembic/versions/*.py files exist, failing if a service has model changes without a migration.
