- test_parse_chunk_message_id.py (5 tests) - _parse_chunk propagates

message_id for thought, observation, answer; handles missing gracefully
- test_explainability_parsing.py (+1) - test_dispatches_analysis_with_tooluse
  - Analysis+ToolUse mixin still dispatches to Analysis
- test_explainability.py (+1) - test_observation_found_via_subtrace_synthesis
  - chain walker follows from sub-trace Synthesis to find Observation and
  Conclusion in correct order
  - test_agent_provenance.py (+8) - session parent_uri (2), synthesis
  single/multiple parents, types, document, label (6)
