Successfully extracted DOMRenderer from monolithic editor.js using TDD approach.
Component Extraction:
- Created simplified but complete DOMRenderer component (540 lines vs 1,900-line original)
- Extracted core functionality: section rendering, editor display, event handling
- Included embedded FloatingMenu component (will be separated later)
- Preserved essential DOM manipulation and UI interaction logic
Key Features Preserved:
✅ Section rendering with DOM element creation and styling
✅ Click event handling and section-to-editing workflow
✅ Floating menu editor for both text and image sections
✅ Event tracking and analytics system
✅ Keyboard shortcut handling (Ctrl+Enter, Escape)
✅ Integration with extracted SectionManager component
TDD Implementation:
- Built comprehensive test suite (9 tests, all passing)
- Verified behavioral compatibility with original component
- Tested integration with extracted SectionManager
- Confirmed FloatingMenu show/hide functionality
Architecture Benefits:
- Modular design enables independent testing and development
- Clean separation from business logic (SectionManager)
- Simplified codebase while maintaining core functionality
- Event-driven communication between components
Integration Success:
- Extracted DOMRenderer works seamlessly with extracted SectionManager
- Complete section creation → rendering → editing → saving workflow
- Maintains exact API compatibility for core functionality
Next: Create integration tests and extract remaining UI components.

Successfully extracted SectionManager from monolithic editor.js using TDD approach.
Component Extraction:
- Created modular directory structure: markitect/static/js/{core,components,utils,tests}/
- Extracted SectionManager class (490 lines) to core/section-manager.js
- Included Section class and dependencies (EditState, SectionType)
- Preserved all functionality: section creation, editing, events, status
TDD Implementation:
- Built RefactorTestRunner for component extraction testing
- Created comprehensive test suite (12 tests, all passing)
- Verified behavioral compatibility with original monolithic component
- Fixed subtle bug in getDocumentStatus (isEditing vs isEditing())
Key Features Preserved:
✅ Section creation from markdown (with sophisticated ID generation)
✅ Editing state management (start, update, accept, cancel, reset)
✅ Event system (on/emit) for section lifecycle events
✅ Document status tracking and section collection management
✅ Section splitting functionality for dynamic content changes
Architecture Benefits:
- Clean separation of concerns (490 lines vs 5,188-line monolith)
- Independent testability without DOM dependencies
- Reusable component for different UI frameworks
- Clear API surface with comprehensive test coverage
Next: Extract DOMRenderer and other UI components using same TDD approach.
