# @BRIEF Contract tests for the APIKey SQLAlchemy model — creation, hash storage, and field constraints.
# @RELATION BINDS_TO -> [APIKeyModel]
# @TEST_CONTRACT: APIKey model stores SHA-256 hash and prefix; raw key never persisted.
# @TEST_EDGE: key_hash is unique and indexed
# @TEST_EDGE: prefix is exactly 11 chars ("ssk_" + 7)
# @TEST_EDGE: active defaults to True
