- [ ] OTP email contains correct code
- [ ] OTP email renders correctly (no errors)
- [ ] OTP form displays on verification page
- [ ] OTP form validates input correctly

### ✅ User Acceptance Tests

## Security Features Implemented

✅ **OTP Security**
- Random generation using `random_int()`
- 6-digit length (balance of security & usability)
- Numeric only (reduces typos)
- Time-limited (15 minutes)
- Single-use (cleared after verification)
- Database stored (secure)

✅ **Email Security**
- TLS encryption (smtpout.secureserver.net:587)
- Verified sender address
- Professional template with warnings
- No sensitive data in plain text
- Secure from verified company email

✅ **Session Security**
- Authentication required (auth:client middleware)
- CSRF protection (Laravel tokens)
- IP logging (stored in ClientEditOtp)
- User agent logging (stored in ClientEditOtp)
- Audit trail (activity logging)

✅ **Access Control**
- Only authenticated clients can access
- Clients can only access their own requests
- Time-limited edit access (7 days)
- Edit access expires after time limit
- Admin can view all requests

---

## Performance Considerations

### Email Delivery
**Current**: Synchronous (blocking)
**Recommendation**: Convert to queue in production

```php
// app/Mail/EditAccessOtpMail.php
class EditAccessOtpMail extends Mailable implements ShouldQueue
{
    use Queueable;
}
```

### Database Queries
- OTP lookup uses indexed `client_id`
- Efficient queries with proper WHERE clauses
- No N+1 query problems

### Cleanup
**Add to scheduler** (`app/Console/Kernel.php`):
```php
$schedule->call(function () {
    \App\Models\ClientEditOtp::cleanupExpired();
})->daily();
```
