- stun: RFC 5389 binding responder + RFC 5780 attributes (OTHER-ADDRESS,
RESPONSE-ORIGIN, CHANGE-REQUEST) on a primary/alt-port socket grid per
address; advertises stun-5780 with >=2 same-family addrs, else
stun-basic. Unmodified framing for tooling interop. Tested.
- tcpecho: JSON greeting with observed src + TCP_INFO MSS/options
(Linux getsockopt; zeroed elsewhere via build tags), then byte echo.
- session: per-packet UDP observations + connect-back results, ByID lookup.
- control: GET /v1/sessions/{id}/observations, POST .../actions
(delayed_echo → DELAYED_ECHO at the observed data-plane source;
connect_back → dial the control-plane source, record connected/refused/
timeout+rtt). Capabilities computed from what is actually wired.
- config/main: comma-separated STUN listeners; all planes bind explicit
addresses; graceful shutdown of the new listeners.
Full flow smoke-tested; go test green (stun binding/change-port,
dataplane wire format).
