Task 2.1 of mma_pipeline_fix_20260301: capture comms baseline before send(), then sum input_tokens/output_tokens from IN/response entries to populate engine.tier_usage['Tier 3'].
Tasks 1.1, 1.2, 1.3 of mma_pipeline_fix_20260301:
- Task 1.1: Add [MMA] diagnostic print before _queue_put in run_worker_lifecycle; enhance except to include traceback
- Task 1.2: Replace unsafe event_queue._queue.put_nowait() else branches with RuntimeError in run_worker_lifecycle, confirm_execution, confirm_spawn
- Task 1.3: Verified run_in_executor positional arg order is correct (no change needed)
Three independent root causes fixed:
- gui_2.py: Route mma_spawn_approval/mma_step_approval events in _process_event_queue
- multi_agent_conductor.py: Pass asyncio loop from ConductorEngine.run() through to
thread-pool workers for thread-safe event queue access; add _queue_put helper
- ai_client.py: Preserve GeminiCliAdapter in reset_session() instead of nulling it
Test: visual_sim_mma_v2::test_mma_complete_lifecycle passes in ~8s

Applied 236 return type annotations to functions with no return values
across 100+ files (core modules, tests, scripts, simulations).
Added Phase 4 to python_style_refactor track for remaining 597 items
(untyped params, vars, and functions with return values).
