## 🔧 Technical Implementation

### Database Schema
```
activity_logs table:
- id (Primary Key)
- user_id (Foreign Key → users)
- action (create, update, delete, export, login)
- description (Human-readable text)
- model_type (Kontrakan, Laundry, SAW, User)
- model_id (Nullable - for bulk exports)
- old_values (JSON)
- new_values (JSON)
- ip_address
- user_agent
- created_at, updated_at

Indexes:
- user_id (for user activity lookup)
- created_at (for date filtering)
- action (for action type filtering)
- model_type (for model filtering)
```

### Logging Pattern Used
```php
// Standard logging call
ActivityLog::log(
    'action_type',           // 'create', 'update', 'delete', 'export'
    'description',           // Human readable description
    'ModelType',            // 'Kontrakan', 'Laundry', 'SAW'
    $modelId,               // ID of affected model (null for exports)
    $oldValues,             // Optional: array of old values
    $newValues              // Optional: array of new values
);
```

### Integration Points
```
KontrakanController
  → store() → ActivityLog::log('create', ..., 'Kontrakan', $kontrakan->id)
  → update() → ActivityLog::log('update', ..., 'Kontrakan', $kontrakan->id, $oldValues, $newValues)
  → destroy() → ActivityLog::log('delete', ..., 'Kontrakan', $kontrakan->id, $oldValues, [])
  → bulkDestroy() → ActivityLog::log('delete', ..., 'Kontrakan', $id) × n

LaundryController
  → store() → ActivityLog::log('create', ..., 'Laundry', $laundry->id)
  → update() → ActivityLog::log('update', ..., 'Laundry', $laundry->id, $oldValues, $newValues)
  → destroy() → ActivityLog::log('delete', ..., 'Laundry', $laundry->id, $oldValues, [])
  → bulkDestroy() → ActivityLog::log('delete', ..., 'Laundry', $id) × n

ExportController
  → kontrakanExcel() → ActivityLog::log('export', ..., 'Kontrakan', null)
  → kontrakanPDF() → ActivityLog::log('export', ..., 'Kontrakan', null)
  → laundryExcel() → ActivityLog::log('export', ..., 'Laundry', null)
  → laundryPDF() → ActivityLog::log('export', ..., 'Laundry', null)
  → sawResultsExcel() → ActivityLog::log('export', ..., 'SAW', null)
  → sawResultsPDF() → ActivityLog::log('export', ..., 'SAW', null)
```
