Rule 9 — Hermes API Lockdown Active.
Port 8642 is permanently bound to 127.0.0.1 (loopback only) and
protected behind HERMES_API_KEY bearer authentication. It is never proxied
through Nginx. Access is restricted to container-internal ai-net
communication (openclaw → hermes:8642) or authorized SSH tunneling exclusively.
Public exposure of port 8642 constitutes a Critical Security Violation.
