+# Comprehensive Debrief: GUI Decoupling Track (Botched Implementation)
+
+## 1. Track Overview
+*   **Track Name:** GUI Decoupling & Controller Architecture
+*   **Track ID:** `gui_decoupling_controller_20260302`
+*   **Primary Objective:** Decouple business logic from `gui_2.py` (3,500+ lines) into a headless `AppController`.
+
+## 2. Phase-by-Phase Failure Analysis
+
+### Phase 1: Controller Skeleton & State Migration
+*   **Status:** [x] Completed (with major issues)
+*   **What happened:** State variables (locks, paths, flags) were moved to `AppController`. `App` was given a `__getattr__` and `__setattr__` bridge to delegate to the controller.
+*   **Failure:** The delegation created a "Phantom State" problem. Sub-agents began treating the two objects as interchangeable, but they are not. Shadowing (where `App` has a variable that blocks `Controller`) became a silent bug source.
+
+### Phase 2: Logic & Background Thread Migration
+*   **Status:** [x] Completed (with critical regressions)
+*   **What happened:** Async loops, AI client calls, and project I/O were moved to `AppController`. 
+*   **Failure 1 (Over-deletion):** Tier 3 workers deleted essential UI-thread handlers from `App` (like `_handle_approve_script`). This broke button callbacks and crashed the app on startup.
+*   **Failure 2 (Thread Violation):** A "fallback queue processor" was added to the Controller thread. This caused two threads to race for the same event queue. If the Controller won, the UI never blinked/updated, causing simulation timeouts.
+*   **Failure 3 (Property Erasure):** During surgical cleanups in this high-reasoning session, the `current_provider` getter/setter in `AppController` was accidentally deleted while trying to remove a redundant method. `App` now attempts to delegate to a non-existent attribute, causing `AttributeError`.
+
+### Phase 3: Test Suite Refactoring
+*   **Status:** [x] Completed (fragile)
+*   **What happened:** `conftest.py` was updated to patch `AppController` methods.
+*   **Failure:** The `live_gui` sandbox environment (isolated workspace) was broken because the Controller now eagerly checks for `credentials.toml` on startup. The previous agent tried to "fix" this by copying secrets into the sandbox, which is a security regression and fragile.
+
+### Phase 4: Final Validation
+*   **Status:** [ ] FAILED
+*   **What happened:** Integration tests and extended simulations fail or timeout consistently.
+*   **Root Cause:** Broken synchronization between the Controller's background processing and the GUI's rendering loop. The "Brain" (Controller) and "Limb" (GUI) are disconnected.
+
+## 3. Current "Fucked" State of the Codebase
+*   **`src/gui_2.py`:** Contains rendering but is missing critical property logic. It still shadows core methods that should be purely in the controller.
+*   **`src/app_controller.py`:** Missing core properties (`current_provider`) and has broken `start_services` logic.
+*   **`tests/conftest.py`:** Has a messy `live_gui` fixture that uses environment variables (`SLOP_CREDENTIALS`, `SLOP_MCP_ENV`) but points to a sandbox that is missing the actual files.
+*   **`sloppy.py`:** The entry point works but the underlying classes are in a state of partial migration.
+
+## 4. Immediate Recovery Plan (New Phase 5)
+
+### Phase 5: Stabilization & Cleanup
+1.  **Task 5.1: AST Synchronization Audit.** Manually (via AST) compare `App` and `AppController`. Ensure every property needed for the UI exists in the Controller and is correctly delegated by `App`.
+2.  **Task 5.2: Restore Controller Properties.** Re-implement `current_provider` and `current_model` in `AppController` with proper logic (initializing adapters, clearing stats).
+3.  **Task 5.3: Explicit Delegation.** Remove the "magic" `__getattr__` and `__setattr__`. Replace them with explicit property pass-throughs. This will make `AttributeError` visible during static analysis rather than runtime.
+4.  **Task 5.4: Fix Sandbox Isolation.** Ensure `live_gui` fixture in `conftest.py` correctly handles `credentials.toml` via `SLOP_CREDENTIALS` env var pointing to the root, and ensure `sloppy.py` respects it.
+5.  **Task 5.5: Event Loop Consolidation.** Ensure there is EXACTLY ONE `asyncio` loop running, owned by the Controller, and that the GUI thread only reads from `_pending_gui_tasks`.
+
+## 5. Technical Context for Next Session
+*   **Encoding issues:** `temp_conftest.py` and other git-shipped files often have UTF-16 or different line endings. Use Python-based readers to bypass `read_file` failures.
+*   **Crucial Lines:** `src/gui_2.py` line 180-210 (Delegation) and `src/app_controller.py` line 460-500 (Event Processing) are the primary areas of failure.
+*   **Mocking:** All `patch` targets in `tests/` must now be audited to ensure they hit the Controller, not the App.
