+Die Implementierung ist vollständig und bereit für die Integration mit externen Apps.
+
+## Neue STOMP-Schnittstelle: Task-Erledigung melden
+
+Mit dieser Schnittstelle kann ein Client die Erledigung eines Tasks melden.
+
+- Senden (Client → Server): `/app/task/completed`
+- Broadcasts (Server → Client):
+  - Global: `/topic/task-updates`
+  - Task-spezifisch: `/topic/tasks/{taskId}`
+
+Payload (JSON):
+
+```json
+{
+  "taskId": "<MongoId als String>",
+  "completedBy": "<optional: Name/ID des Ausführenden>",
+  "note": "<optional: Kommentar>"
+}
+```
+
+Antwort (Beispiel):
+
+```json
+{
+  "timestamp": "2025-09-05T09:25:00",
+  "type": "taskCompletedAck",
+  "success": true,
+  "taskId": "...",
+  "jobId": "...",
+  "completed": true,
+  "completedAt": "2025-09-05T09:25:00",
+  "completedBy": "driver01",
+  "note": "Übergabe erfolgreich",
+  "event": "taskCompleted"
+}
+```
+
+JavaScript Beispiel:
+
+```javascript
+// Abonnieren der globalen Updates
+stompClient.subscribe('/topic/task-updates', (frame) => {
+  console.log('Task update:', JSON.parse(frame.body));
+});
+
+// Abonnieren eines spezifischen Tasks
+stompClient.subscribe('/topic/tasks/' + taskId, (frame) => {
+  console.log('Task-specific update:', JSON.parse(frame.body));
+});
+
+// Task als erledigt melden
+stompClient.send('/app/task/completed', {}, JSON.stringify({
+  taskId: taskId,
+  completedBy: 'driver01',
+  note: 'Übergabe erfolgreich'
+}));
+```
+
+Flutter/Dart Beispiel:
+
+```dart
+stompClient.subscribe(
+  destination: '/topic/task-updates',
+  callback: (frame) => print('Task update: ${frame.body}'),
+);
+
+stompClient.subscribe(
+  destination: '/topic/tasks/$taskId',
+  callback: (frame) => print('Task-specific update: ${frame.body}'),
+);
+
+stompClient.send(
+  destination: '/app/task/completed',
+  body: jsonEncode({
+    'taskId': taskId,
+    'completedBy': 'driver01',
+    'note': 'Übergabe erfolgreich',
+  }),
+);
+```
+
+Hinweise:
+- `taskId` ist Pflicht. Bei ungültiger oder unbekannter `taskId` wird `success=false` zurückgegeben.
+- Der Server setzt `completed=true` und `completedAt` automatisch.
+- Zusätzlich zum globalen Broadcast wird ein task-spezifisches Event auf `/topic/tasks/{taskId}` versendet.
