Backend model migration sync rule. Scope: - Applies only when runtime model files change under `domains/python/backend/app/src/models/**`. - Ignore test-only, docs-only, comment-only, and `__init__.py`-only changes. Trigger: - At least one changed model file adds/removes schema declarations, including: - `models.<FieldType>(...)` field assignments, - relationship fields (`ForeignKey`, `ManyToManyField`, `OneToOneField`), - model `Meta` schema attributes (`indexes`, `constraints`, `unique_together`, `index_together`, `db_table`). Hard requirements: 1) At least one migration file must be added or changed under `domains/python/backend/app/src/migrations/**`. Decision: - Return NOT APPROVED when the trigger is met and no migration file change is present. - Otherwise APPROVED for this policy.
