…e (DQ-665) - Add DataContractSpec unit tests (parsing, mutation, YAML roundtrip) and ContractClient unit tests (generate_initial_spec, delete, delete_latest_version header assertions) to both pyatlan and pyatlan_v9 test suites - Add sync integration tests for generate_initial_spec, spec-based contract creation, delete_all, and delete_latest_version (xfail: Atlas NPE on dq-dev until backend version-chain schema is deployed) in data_mesh_test.py and v9 - Add async integration tests for the same scenarios in aio/test_client.py for both pyatlan and pyatlan_v9 - Move CONTRACT_DELETE_SCOPE_HEADER constant from contract.py / aio/contract.py into pyatlan/client/constants.py (single source of truth across 4 files) - Add Optional[Dict[str, str]] type hints to extra_headers param in atlan.py, aio/client.py, and protocol.py (ApiCaller + AsyncApiCaller) Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
