| 93 | + |
| 94 | +### 6. Remote Candidate Behavior |
| 95 | +Command: |
| 96 | +```bash |
| 97 | +node --input-type=module - |
| 98 | +``` |
| 99 | +Inline execution validated non-loopback LAN path (`lanIp=192.168.2.58`): |
| 100 | +- non-loopback without key blocked |
| 101 | +- non-loopback with valid key allowed |
| 102 | +- session lifecycle states visible via remote metrics polling |
| 103 | + |
| 104 | +Evidence: |
