+**Final state (from the user's full batch run on 2026-07-01):** 7 of 11 tiers PASS. 2 FAIL:
+
+1. `tier-1-unit-gui` — `test_phase_8_invariant_property_setter_count_dropped` and `test_phase_9_invariant_helper_utility_count_dropped` flagged my new `except Exception` in `render_task_dag_panel` as INTERNAL_BROAD_CATCH.
+2. `tier-3-live_gui` — `test_visual_sim_mma_v2::test_mma_complete_lifecycle` failed at "No proposed_tracks after 120s" due to mma_status endpoint crashing with `TypeError: Object of type ErrorInfo is not JSON serializable`.
+
+Both fixed in commit `1c31c603`:
+- The `except Exception` now converts to `ErrorInfo(...)` via `from src.result_types import ErrorInfo, ErrorKind` before draining, so the audit recognizes the canonical BOUNDARY_CONVERSION pattern.
+- The mma_status endpoint now uses `_serialize_for_api` on the 4 collection fields (`active_track`, `active_tickets`, `tracks`, `proposed_tracks`, `tier_usage`) that can hold non-primitive types. The helper was extended to handle `ErrorInfo` instances. Targeted serialization keeps the endpoint fast (avoids the test_visual_mma slow-path regression I hit when I wrapped the whole result).
 
 **Resolution of the final blocker (`test_undo_redo_lifecycle`):** The ImGui-state imbalance was actually a *Python* AttributeError, not an ImGui-internal one. The prior test in batch (`test_mma_concurrent_tracks_sim`) leaves dict-typed ticket entries in `app.active_tickets` (created via the Add Ticket form path which builds dicts, not Ticket dataclass instances). When `render_task_dag_panel` iterates and does `t.id`, the dict raises AttributeError, and imgui-node-editor's internal state becomes unbalanced. The "Missing PopID()" is the *symptom*; the cause is the Python exception.
