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

## Phase 1: Controller Skeleton & State Migration
- [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] WHERE: Project root
    - [x] WHAT: `uv run pytest`
    - [x] HOW: Ensure 100% pass rate. (344 passed, 1 skipped, 2 warnings)
    - [x] SAFETY: Watch out for lingering thread closure issues.
- [ ] Task: Conductor - User Manual Verification 'Phase 4: Final Validation' (Protocol in workflow.md)

## Phase 5: Stabilization & Cleanup (RECOVERY)
- [x] Task: Task 5.1: AST Synchronization Audit [16d337e]
- [x] Task: Task 5.2: Restore Controller Properties (Restore `current_provider`) [2d041ee]
- [ ] 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] Task: Task 5.6: Fix `test_gui_provider_list_via_hooks` workspace creation
    - [x] WHERE: tests/conftest.py:189-191
    - [x] WHAT: Add `temp_workspace.mkdir(parents=True, exist_ok=True)` before writing files
    - [x] HOW: The workspace directory was being deleted but not recreated before file writes
    - [x] SAFETY: Non-blocking, standard directory creation
- [x] Task: Task 5.7: Fix `test_live_gui_integration` event loop issue
    - [x] WHERE: tests/test_live_gui_integration.py:34-40, 77
    - [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
