## Security Implementation

### Authentication:
- Session-based authentication
- Role-based access control (admin, vendor, staff, sales)
- Protected routes with middleware
- Auto-logout on status change

### Authorization:
- Ownership verification (products, orders)
- Admin-only actions (approve/reject)
- Protected system admin (admin2)

### Data Protection:
- SQL injection prevention (mysqli_real_escape_string)
- XSS protection (htmlentities)
- Password hashing (MD5 - recommend bcrypt upgrade)
- Security headers (X-Frame-Options, etc.)

---

## Business Logic

### Commission System:
- **Default Rate:** 10%
- **Platform Take:** 10%
- **Vendor Keep:** 90%
- **Configurable:** Per-vendor rates supported

**Calculation:**
```php
$orderAmount = $price * $quantity
$commissionAmount = $orderAmount * (commission_rate / 100)
$vendorEarning = $orderAmount - $commissionAmount
```

### Approval Workflows:

**Vendor Registration:**
```
Apply → Pending → Admin Approval → Active or Rejected
```

**Product Listing:**
```
Create → Pending → Admin Approval → Approved or Rejected
```

**Payout Process:**
```
Request → Pending → Admin Processing → Completed or Failed
```
