 **Scope:** Phase 1 (Update MMA Skill prompts) → Phase 2 (Update `workflow.md`).
 
+### `architecture_boundary_hardening_20260302` (initialized)
+**Priority:** High
+**Depends on:** None
+**Track dir:** `conductor/tracks/architecture_boundary_hardening_20260302/`
+
+**Audit-confirmed gaps:**
+- `ai_client.py` loops execute `set_file_slice` and `py_update_definition` instantly without checking `pre_tool_callback`, bypassing GUI approval.
+- `mma_exec.py` bypasses skeletonization for `mcp_client`, causing token bloat.
+- `dag_engine.py` does not cascade `blocked` states, causing orchestrator infinite loops.
+
+**Scope:** Phase 1 (Meta-tooling token fix) → Phase 2 (Seal GUI HITL bypass) → Phase 3 (Fix DAG Engine cascading blocks).
