+# Track Specification: GUI Decoupling & Controller Architecture (gui_decoupling_controller_20260302)
+
+## Overview
+`gui_2.py` currently operates as a Monolithic God Object (3,500+ lines). It violates the Data-Oriented Design heuristic by owning complex business logic, orchestrator hooks, and markdown file building. This track extracts the core state machine and lifecycle into a headless `app_controller.py`, turning the GUI into a pure immediate-mode view.
+
+## Architectural Constraints: The "Immediate Mode View" Contract
+- **No Business Logic in View**: `gui_2.py` MUST NOT perform file I/O, AI API calls, or subprocess management directly.
+- **State Ownership**: `app_controller.py` (or equivalent) owns the "Source of Truth" state.
+- **Event-Driven Mutations**: The GUI must mutate state exclusively by dispatching events or calling controller methods, never by directly manipulating backend objects in the render loop.
+
+## Functional Requirements
+- **Controller Extraction**: Create `app_controller.py` to handle all non-rendering logic.
+- **State Migration**: Move state variables (`_tool_log`, `_comms_log`, `active_tickets`, etc.) out of `App.__init__` into the controller.
+- **Logic Migration**: Move background threads, file reading/writing (`_flush_to_project`), and AI orchestrator invocations to the controller.
+- **View Refactoring**: Refactor `gui_2.py` to accept the controller as a dependency and merely render its current state.
+
+## Acceptance Criteria
+- [ ] `app_controller.py` exists and owns the application state.
+- [ ] `gui_2.py` has been reduced in size and complexity (no file I/O or AI calls).
+- [ ] All existing features (chat, tools, tracks) function identically.
+- [ ] The full test suite runs and passes against the new decoupled architecture.
