## How It Works Now

### Automatic PDF Generation
```
1. Will created by client/admin
2. Client fills all details
3. Admin reviews and marks as "finalized"
4. System automatically:
   - Loads all will relationships
   - Renders admin.wills.show template with data
   - Converts HTML to PDF using mPDF
   - Saves PDF to: storage/app/private/wills/will_209_TIME.pdf
   - Stores path in: wills.pdf_file_path
5. PDF ready for use
```

### Storage Form Usage
```
1. Admin goes to /admin/storage/create
2. Selects will from dropdown
3. AJAX calls: GET /admin/storage/fetch-will-pdf/209
4. Controller checks:
   - Is PDF saved in database?
   - If yes → load from disk (fast)
   - If no → generate new PDF (slow first time)
5. PDF loads in preview (2-3 seconds max)
6. Shows complete will information
7. Admin verifies and completes storage
```

### Beneficiary Access
```
1. Beneficiary receives PDF with QR code
2. Beneficiary can:
   - Download professional PDF
   - Verify authenticity via QR
   - Access via verification URL
   - View scan history
   - Confirm document is legitimate
```

---

## Setup (5 Minutes)

### 1. Run Migration
```bash
php artisan migrate
```

### 2. Create Directory
```bash
mkdir -p storage/app/private/wills
chmod 755 storage/app/private/wills
```

### 3. Add Trigger (Choose One)

**Option A: Model Boot (Recommended)**

Add to `app/Models/Will.php` boot() method:

```php
static::updated(function ($will) {
    if ($will->isDirty('status') && $will->status === 'finalized') {
        try {
            app(\App\Http\Controllers\WillStorageController::class)
                ->generateAndSaveWillPdf($will);
        } catch (\Exception $e) {
            \Log::error('PDF generation failed', ['will_id' => $will->id]);
        }
    }
});
```

**Option B: Manual Command**

Run manually when needed:

```bash
php artisan tinker
$will = Will::find(209);
app(\App\Http\Controllers\WillStorageController::class)->generateAndSaveWillPdf($will);
```

### 4. Test
```
1. Go to /admin/storage/create
2. Select a finalized will
3. Watch PDF load
4. Should see complete will data
```
