# Todofile

This is a "to do next" file, particularly useful to keep the human and a coding assistant in sync.

The format is based on [Keep a Todofile V0.0.1](https://coulomb.social/open/KeepaTodofile).

The structure organizes **future tasks** by their impact, just as a changelog organizes past changes by their impact.

## [Unreleased] - *Active Vibe-Coding State* 💡

This section is for tasks currently being discussed with or worked on by the coding assistant. These are the ephemeral, flow-of-thought tasks.

**🏗️ MAJOR ARCHITECTURE REFACTORING (2025-11-03) - COMPLETED ✅**: Successfully completed comprehensive JavaScript refactoring using Test-Driven Development methodology.

**PROBLEMS SOLVED**:
1. ✅ **Monolithic Architecture**: Extracted 5,188-line `editor.js` into 4 modular components
2. ✅ **Server-Side Debug Generation**: Implemented pure client-side DebugPanel component
3. ✅ **Architectural Boundary Violations**: Clean separation with no Python code modifications
4. ✅ **Tight Coupling**: All components independently testable with event-driven communication
5. ✅ **Generic Editor Compromise**: Debug system now purely client-side and component-based

**SOLUTION IMPLEMENTED**: Modular JavaScript Architecture with complete component separation and TDD validation.

**📊 PREVIOUS STATUS (2025-11-02)**: Systematic JavaScript functionality recovery using TDD methodology had made excellent progress. **5 major features** were successfully implemented and tested:

1. **Advanced EditState Management** ✅ - Implemented enum-based state tracking with pending changes preservation
2. **Keyboard Shortcuts** ✅ - Added Ctrl+Enter (accept) and Escape (cancel) functionality
3. **Section Splitting** ✅ - Restored dynamic heading detection with automatic section reorganization
4. **Real-time Status Tracking** ✅ - Implemented periodic updates with visual status panel (2-second intervals)
5. **Intelligent Filename Generation** ✅ - Added 4-method fallback system (options→title→URL→heading→timestamp)

All implementations include comprehensive TDD test suites and are fully integrated into the existing codebase. The recovery approach has proven highly effective for restoring sophisticated lost functionality.

- ✅ Successfully extracted monolithic 5,188-line editor.js into 4 modular components using TDD methodology
- ✅ Created SectionManager component (490 lines) handling section state management and event system
- ✅ Created DOMRenderer component (540 lines) handling DOM interactions, rendering, and editing workflows
