+## 15. Modular Controller Pattern
+
+To prevent "God Object" bloat in core controllers (like `AppController`):
+- **Extract Logic:** Move all state-independent or purely utility logic to module-level functions.
+- **Dependency Injection:** Module-level functions that require class state should accept the instance as their first argument (e.g., `def my_extracted_logic(controller: AppController, ...)`).
+- **Handler Maps:** Replace massive `if/elif` blocks (like those in event dispatchers) with dictionaries mapping keys to module-level handler functions.
+- **Inner Class Extraction:** Never define nested classes or functions within methods. Move them to the module level.

 - **Strict State Management:** There must be a rigorous separation between the Main GUI rendering thread and daemon execution threads. The UI should *never* hang during AI communication or script execution. Use lock-protected queues and events for synchronization.
 - **Comprehensive Logging:** Aggressively log all actions, API payloads, tool calls, and executed scripts. Maintain timestamped JSON-L and markdown logs to ensure total transparency and debuggability.
 - **Mandatory ImGui Verification:** All changes to the GUI (`gui_2.py`) MUST be verified using the custom AST linter (`scripts/check_imgui_scopes.py`) to ensure all ImGui scopes (begin/end, push/pop) are properly matched. Developers should prioritize the use of `src/imgui_scopes.py` context managers (`imscope`) over manual push/pop calls.
+- **Modular Controller Pattern:** To prevent "God Object" bloat in core controllers (like `AppController`), all state-independent or utility logic must be moved to module-level functions. Functions requiring class state should accept the instance as an explicit dependency (`def logic(controller: AppController, ...)`). Massive `if/elif` dispatch blocks must be refactored into handler maps (dictionaries) of module-level functions.
 - **Dependency Minimalism:** Limit external dependencies where possible. For instance, prefer standard library modules (like `urllib` and `html.parser` for web tools) over heavy third-party packages.

+# Specification: AppController Curation & Structural Alignment
+
+## Context
+Following the successful cleanup and refactoring of `gui_2.py`, the same organizational patterns and AI-optimized coding conventions must be applied to `src/app_controller.py`. This module is a critical part of the Manual Slop architecture, acting as the bridge between the GUI and the underlying AI/MCP systems.
+
+## Goals
+1. **Structural Parity:** Reorganize `src/app_controller.py` to match the structure and quality of `gui_2.py`.
+2. **Standardization:** Enforce the AI-Optimized Python Style Guide (1-space indent, minimal blank lines, type hints, SDM tags).
+3. **Refactoring:** Identify and extract logic that violates the 5-level nesting limit or is better suited as module-level functions.
+4. **Validation:** Ensure full system integrity via the comprehensive test suite, run in batches of 4.
+
+## Scope
+- `src/app_controller.py`: Primary target for refactoring and curation.
+- `conductor/code_styleguides/python.md`: Potential updates if new nuances are found.
+- `conductor/product-guidelines.md`: Potential updates based on structural findings.
+
+## Constraints
+- **Indentation:** Must be exactly 1 space.
+- **Scoping:** Use `imscope` for any ImGui-related calls if present (though `app_controller` should ideally be logic-focused, some status rendering might exist).
+- **Anti-OOP:** Move state-independent methods to module level.
+- **Type Safety:** 100% type hint coverage for all modified sections.
