| 2 | Forward newly-created CoPilot alerts to the SOCFortress MDR server. |
| 3 | |
| 4 | When MDR forwarding is enabled (MDR_ENABLED) and a customer has the |
| 5 | "SOCFortress MDR" integration deployed, this module POSTs the alert's indexer |
| 6 | pointers + CoPilot alert ID to the MDR server: |
| 7 | |
| 8 | POST {MDR_SERVER_URL}/api/v1/alerts/copilot |
| 9 | { |

| 13 | "copilot_alert_id": <CoPilot alert id> |
| 14 | } |
| 15 | |
| 16 | The MDR server authenticates the request by the collector UUID (no bearer |
| 17 | token) and then tasks the customer's collector to fetch the authoritative |
| 18 | document from the Wazuh Indexer. Forwarding is best-effort: failures are logged |
| 19 | and never propagate to alert creation. |
