Two new cases in test_thread_data_middleware.py pin the merge contract between PR (frozen DeerFlowContext) and release/2.0-rc (HumanMessage stamping logic): - test_before_agent_stamps_run_id_and_timestamp_on_last_human_message: given DeerFlowContext(run_id="r-stamp"), the trailing HumanMessage in state gets additional_kwargs["run_id"] == "r-stamp" and a timestamp; id and name are preserved/normalized. - test_before_agent_stamps_none_run_id_when_context_omits_it: run_id is optional on DeerFlowContext, so middleware must stamp None gracefully rather than raise. These were the smoke target for the merge: prior to this commit the only signal that runtime.context.run_id worked end-to-end was a manual gateway run.
