# #region Test.AdminApiKeys.Unit [C:2] [TYPE Module] [SEMANTICS test,admin,api_key,crud]
# @BRIEF Unit tests for admin_api_keys.py route handler logic — validation, edge cases, invariants.
# @RELATION BINDS_TO -> [AdminApiKeyRoutes]
# @TEST_CONTRACT: create_api_key -> validates name/permissions, generates key, returns raw key once
# @TEST_CONTRACT: list_api_keys -> never returns key_hash or raw_key
# @TEST_CONTRACT: revoke_api_key -> soft-deletes (active=False), 404 for already revoked
# @TEST_EDGE: create_api_key_empty_name -> raises 400
# @TEST_EDGE: create_api_key_empty_permissions -> raises 400
# @TEST_EDGE: revoke_api_key_not_found -> raises 404
# @TEST_EDGE: revoke_api_key_already_revoked -> raises 404
# @TEST_EDGE: list_api_keys_empty_db -> returns empty list
