# Implementation Plan: AppController Curation [checkpoint: fa4388b]

## Phase 1: Structural Audit & Conventions Update [checkpoint: 511aabb]
- [x] Task: Audit `src/app_controller.py` against `gui_2.py` organization and the Python Style Guide. [511aabb]
- [x] Task: Identify methods for extraction to module level (Anti-OOP enforcement). [511aabb]
- [x] Task: Update `conductor/code_styleguides/python.md` or `product-guidelines.md` if any new nuances are discovered in `gui_2.py`. [511aabb]
- [x] Task: Conductor - User Manual Verification 'Phase 1: Structural Audit' (Protocol in workflow.md) [511aabb]

## Phase 2: Refactoring & Curation [checkpoint: fa4388b]
- [x] Task: Apply 1-space indentation and remove excessive blank lines in `src/app_controller.py`. [fa4388b]
- [x] Task: Clean up and organize `AppController.__init__` state declarations. [fa4388b]
- [x] Task: Implement missing type hints and SDM tags. [fa4388b]
- [x] Task: Extract identified logic to module-level functions. [fa4388b]
- [x] Task: Conductor - User Manual Verification 'Phase 2: Refactoring & Curation' (Protocol in workflow.md) [fa4388b]

## Phase 3: Validation & Regression Testing [checkpoint: fa4388b]
- [x] Task: Run the full test suite in batches of 4 files per test run. [fa4388b]
- [x] Task: Fix any regressions or type errors discovered during testing. [fa4388b]
- [x] Task: Conductor - User Manual Verification 'Phase 3: Validation & Regression Testing' (Protocol in workflow.md) [fa4388b]
