# #region Test.Integration.Validation [C:4] [TYPE Module] [SEMANTICS test,integration,validation,postgres,testcontainers]
# @BRIEF Integration tests for Validation models (ValidationPolicy, LLMProvider, ValidationRun, ValidationRecord)
#         against real PostgreSQL via Testcontainers. Tests FK constraints, JSONB, CASCADE deletes, ILIKE search.
# @RELATION BINDS_TO -> [ValidationPolicy]
# @RELATION BINDS_TO -> [LLMProvider]
# @RELATION BINDS_TO -> [ValidationRun]
# @RELATION DEPENDS_ON -> [IntegrationTestConftest]
# @PRE Docker daemon running; testcontainers PostgresContainer can start.
# @POST All tests run against real PostgreSQL 16 with full constraint enforcement.
# @TEST_EDGE: policy_cascade_delete -> Deleting a policy cascades to runs, records, sources
# @TEST_EDGE: provider_required_fields -> Missing required provider fields raises IntegrityError
# @TEST_EDGE: jsonb_query -> JSONB fields are queryable with PostgreSQL operators
# @TEST_EDGE: policy_search_ilike -> ILIKE search on policy name works
# @TEST_EDGE: run_status_transition -> Run status updates preserve record integrity
# @TEST_EDGE: policy_create_roundtrip -> Full create/read/update of ValidationPolicy
# @TEST_EDGE: unique_constraint_sources -> No duplicate sources per policy
# @TEST_EDGE: policy_dashboard_ids_jsonb -> dashboard_ids stored and retrieved as JSON
