| Append network-sensor telemetry (Zeek / Suricata / nginx) to each case export. |

| These indices are tagged with the SENSOR's host.name, not the victim's, so they are |
| filtered by the attack IP tuple instead of host.name (unlike export_dataset.py which does |
| endpoint by host). Run AFTER export_dataset.py; appends to each case's security.ndjson. |
