Excellent! All done. Here's a summary of what was completed:

## ✅ Node.js CLI Todo App - Complete

I've built a fully functional Node.js CLI todo app with all requested features:

### **Features Implemented:**
- ✅ **Add** - Add new todos with titles (`todo add <title>`)
- ✅ **List** - View all todos with completion status (`todo list`)
- ✅ **Complete** - Mark todos as complete (`todo complete <id>`)
- ✅ **Delete** - Remove todos (`todo delete <id>`)
- ✅ **Persistence** - Data saved to `todos.json`

### **Project Structure:**
```

├── src/
│   ├── cli.js            # CLI entry point with command routing
│   └── store.js          # TodoStore class handling persistence
└── test/
    └── store.test.js     # 9 comprehensive unit tests
```

### **Tests:** 
All 9 tests passing ✓
