Route::get('skripsi/dashboard', 'SkripsiDashboardController@index')->name('skripsi.dashboard');
Route::get('skripsi/dashboard/data', 'SkripsiDashboardController@getData')->name('skripsi.dashboard.data');
Route::get('skripsi/dashboard/chart-data', 'SkripsiDashboardController@getChartData')->name('skripsi.dashboard.chart-data');

// Skripsi Registration Actions

## 📊 Database Schema Changes

### Table: `application_actions`
```sql
CREATE TABLE `application_actions` (
  `id` bigint UNSIGNED NOT NULL AUTO_INCREMENT,
  `application_id` bigint UNSIGNED NOT NULL,
  `action_type` varchar(255) NOT NULL,
  `action_by` bigint UNSIGNED NULL,
  `notes` text NULL,
  `metadata` json NULL,
  `created_at` timestamp NULL,
  `updated_at` timestamp NULL,
  PRIMARY KEY (`id`),
  KEY `application_actions_application_id_action_type_index` (`application_id`, `action_type`),
  KEY `application_actions_action_by_index` (`action_by`),
  CONSTRAINT `application_actions_application_id_foreign` FOREIGN KEY (`application_id`) REFERENCES `applications` (`id`) ON DELETE CASCADE,
  CONSTRAINT `application_actions_action_by_foreign` FOREIGN KEY (`action_by`) REFERENCES `users` (`id`) ON DELETE SET NULL
);
```

### Table: `skripsi_registrations` (Added Fields)
```sql
ALTER TABLE `skripsi_registrations`
ADD COLUMN `assigned_supervisor_id` bigint UNSIGNED NULL AFTER `preference_supervision_id`,
ADD COLUMN `approval_date` datetime NULL AFTER `assigned_supervisor_id`,
ADD COLUMN `rejection_reason` text NULL AFTER `approval_date`,
ADD COLUMN `revision_notes` text NULL AFTER `rejection_reason`,

'skripsi_dashboard_access',
'skripsi_registration_access',
'skripsi_registration_show',

```

**Untuk membuat permission baru (jika belum ada):**

```php
// database/seeders/PermissionsTableSeeder.php
Permission::create([

]);
```

Kemudian run:
```bash
php artisan db:seed --class=PermissionsTableSeeder
```
