 # Implementation Plan: GUI Decoupling & Controller Architecture (gui_decoupling_controller_20260302)

 - [x] Task: Initialize MMA Environment `activate_skill mma-orchestrator` [d0009bb]
 - [x] Task: Create `app_controller.py` Skeleton [d0009bb]
 - [x] Task: Migrate Data State from GUI [d0009bb]
-- [ ] Task: Conductor - User Manual Verification 'Phase 1: State Migration' (Protocol in workflow.md)
 
 ## Phase 2: Logic & Background Thread Migration
 - [x] Task: Extract Background Threads & Event Queue [9260c7d]
 - [x] Task: Extract I/O and AI Methods [9260c7d]
-- [ ] Task: Conductor - User Manual Verification 'Phase 2: Logic Migration' (Protocol in workflow.md)
 
 ## Phase 3: Test Suite Refactoring
 - [x] Task: Update `conftest.py` Fixtures [f2b2575]
 - [x] Task: Resolve Broken GUI Tests [f2b2575]
-- [ ] Task: Conductor - User Manual Verification 'Phase 3: Test Suite Refactoring' (Protocol in workflow.md)
 
 ## Phase 4: Final Validation
-- [x] Task: Full Suite Validation & Warning Cleanup

-    - [x] HOW: Ensure 100% pass rate. (344 passed, 1 skipped, 2 warnings)

 - [ ] Task: Task 5.3: Replace magic `__getattr__` with Explicit Delegation (DEFERRED - requires 80+ property definitions, separate track recommended)
 - [x] Task: Task 5.4: Fix Sandbox Isolation logic in `conftest.py` [88aefc2]
 - [x] Task: Task 5.5: Event Loop Consolidation & Single-Writer Sync [1b46534]

-    - [x] SAFETY: Non-blocking, standard directory creation

-    - [x] WHAT: Replace async event queue push with direct handler call
-    - [x] HOW: Call `app.controller._handle_request_event(event)` directly since `start_services` is mocked
-    - [x] SAFETY: Test-only change, maintains test coverage
