## Analysis from Logs

### ✅ Admin & Waiter Messages - SENT SUCCESSFULLY

**Log Evidence:**
- **Admin Notification** (Line 4-16):
  - Status: `accepted` by WhatsApp API
  - Message ID: `wamid.HBgMOTE4OTQ5Mjg3MTU0FQIAERgSRUJBRjdGMUREN0Y4NDIyREQ5AA==`
  - Phone: `918949287154`
  - ✅ Successfully sent to WhatsApp API

- **Waiter Notification** (Line 17-29):
  - Status: `accepted` by WhatsApp API
  - Message ID: `wamid.HBgMOTE5Nzg0OTIxNDMxFQIAERgSRTdGOUQ3QUY4RkNGNTRENEI4AA==`
  - Phone: `919784921431`
  - ✅ Successfully sent to WhatsApp API

**Conclusion**: Messages were sent successfully but not delivered. This is a **Meta Business Manager configuration issue**, not a code issue.

**Possible Causes:**
1. Phone numbers not in Meta Business Manager allowed recipient list (for test accounts)
2. Webhook not configured to track delivery status
3. WhatsApp Business Account restrictions

**Solution**: Configure Meta Business Manager:
- Add phone numbers to allowed recipient list
- Configure webhook to receive delivery status updates
- Check WhatsApp Business Account status

### ⚠️ KOT Notification - Job Dispatched But Not Processed

**Log Evidence:**
- Line 31-32: First KOT event triggered, but KOT has no items yet (skipped - correct behavior)
- Line 33-34: Second KOT event triggered, job dispatched successfully
- Lines 35-50: Multiple KOT events triggered (from KotItemObserver when each item is saved)
- All subsequent events skipped with "job already dispatched" (correct behavior - prevents duplicates)

**Issue**: The job was dispatched but **not processed** because:
- **460 pending queue jobs** found in database
- Queue worker is **not running**

**Root Cause**: Queue worker (`php artisan queue:work`) is not running, so jobs are queued but not executed.

**Solution**: 
1. Start queue worker:
   ```bash
   php artisan queue:work
   ```
2. Or process pending jobs:
   ```bash
   php artisan queue:work --once
   ```

---

## The "Job Already Dispatched" Message

**This is CORRECT behavior!**

The message appears because:
1. When a KOT is created, `KotUpdated` event is fired
2. When each KOT item is saved, `KotUpdated` event is fired again (via `KotItemObserver`)
3. If there are 9 items, the event fires 9+ times
4. The listener prevents duplicate notifications by checking if job was already dispatched
5. Only the first event (when items exist) dispatches the job
6. All subsequent events are skipped with "job already dispatched" message

**This prevents sending 9+ duplicate KOT notifications!**

## Verification Steps

### 1. Check Queue Status
```bash
php artisan tinker --execute="
\$pending = \Illuminate\Support\Facades\DB::table('jobs')->count();
echo 'Pending Jobs: ' . \$pending . PHP_EOL;
"
```

### 2. Process Queue Jobs
```bash
# Process one job
php artisan queue:work --once

# Or start continuous worker
php artisan queue:work
```

### 3. Check KOT Notification Logs
```bash
php artisan tinker --execute="
\$logs = \Modules\Whatsapp\Entities\WhatsAppNotificationLog::where('notification_type', 'kitchen_notification')
    ->orderBy('created_at', 'desc')
    ->limit(5)
    ->get(['id', 'status', 'created_at', 'recipient_phone']);
foreach (\$logs as \$log) {
    echo 'Status: ' . \$log->status . ' | Created: ' . \$log->created_at . PHP_EOL;
}
"
```

### 4. Verify Admin/Waiter Messages
- Check Meta Business Manager → Phone Numbers → Allowed Recipients
- Verify webhook is configured
- Check WhatsApp Business Account status

|-------|--------|------------|----------|
| Admin/Waiter Messages | ✅ Sent, ❌ Not Delivered | Meta Business Manager config | Add to allowed list, configure webhook |

## Next Steps

1. **Start Queue Worker**:
   ```bash
   php artisan queue:work
   ```

2. **Configure Meta Business Manager**:

   - Verify messages are received
