## 🔄 Execution Flow - Both Now Identical

```
Step 0: Check & Repair Existing Database
    ↓
    Database exists? 
    ├─ YES: Run SchemaVerifier to verify and repair
    └─ NO: Skip verification
    
Step 1: Create Database
    ↓ CREATE DATABASE IF NOT EXISTS
    
Step 2: Create Tables (18+)
    ├─ users (with credentials, roles, permissions)
    ├─ quality_inspections
    ├─ application_settings
    ├─ qz_pairing_keys
    ├─ api_keys
    ├─ backup_schedules
    ├─ worker_manager_bindings
    ├─ warehouse_locations
    ├─ boxes_crates ← BOX TRACKING
    ├─ box_contents ← BOX TRACKING
    ├─ scanfg_orders (WITH location_id, box_id) ← FG SCAN WITH BOXES
    └─ cp_location_history ← AUDIT TRAIL
    
Step 3: Insert Default Data
    ├─ Create 6 roles
    ├─ Create admin user
    ├─ Create warehouse locations
    └─ Create app settings
    
Step 4: Verify Database
    ├─ Check all tables exist
    ├─ Count records
    └─ Report status
    
✅ Ready for Application

## 🎯 Usage Recommendations

### **Either file can now be used:**

```bash
# Option 1: Use init_db.py
python3 init_db.py

# Option 2: Use initialize_db.py (identical functionality)
python3 initialize_db.py
```

### **For redundancy, use both in sequence:**

```bash
# First initialization
python3 init_db.py

# Second verification/repair (safe to run multiple times)
python3 initialize_db.py

# Or verify with first one again
python3 init_db.py
```

### **For Docker deployment:**

```dockerfile
# Run init_db.py on startup
CMD ["python3", "init_db.py"]
# Or initialize_db.py (now identical)
CMD ["python3", "initialize_db.py"]
```
