 - Use ONLY fields from the JSON spec — no created_at or extra fields
 - Generate EXACTLY 6 tests per entity: create, list, get_by_id, not_found, update, delete
 - No search, filter, or other extra tests
+- test_list: assert len(response.json()) >= 1, NEVER assert == 1 (database is shared between tests)
+- test_create for child entities: create parent FIRST, use parent's id
