## 🔧 **Auto-Fix Technology**
### 🛠️ **How Auto-Fix Works**
```mermaid
graph LR
A[Detect Vulnerability] --> B[Analyze Safe Versions]
B --> C[Create Backup]
C --> D[Update package.json]
D --> E[Regenerate Lock File]
E --> F[Verify Fix]
F --> G[Success ✅]
F --> H[Rollback if Failed ❌]
```
### 🔒 **Safety Features**
