## 🔧 Technical Implementation Details

### CLI Flag System Architecture:
```javascript
// Enhanced Flag System Integration
const { CliIntegration } = require('../lib/cli-flag-managers/cli-integration');

// Intelligent flag detection
const enhancedFlags = ['--save', '--upgrade', '--rollback', '--verify', '--components'];
const hasEnhancedFlags = enhancedFlags.some(flag => args.includes(flag));

// Graceful fallback for environments without enhanced flags
if (!hasEnhancedFlags || !CliIntegration) {
    return await executeWithModularSupport();
}
```

### Modular CLI Structure:
