Review comments at @app/src/webrtc/session.cpp:
- Around line 368-377: Propagate the transport enqueue result through
WebSocketClient::send_message, SignalingClient::send_message, and
WebRtcSession::send_peer_payload; return false when sending cannot be queued.
Set answer_sent_ from send_peer_payload’s result so it reflects queue acceptance
rather than assuming the answer was sent.

Propagate rejected answer sends before setting answer_sent_.
send_peer_payload and both send_message wrappers discard the transport result. A disconnected client or a full outgoing queue can reject the answer, while answer_sent_ is still set to true. A later disconnect log can then report answerSent=1 even though the answer was not queued.
Return the enqueue result through the wrappers and assign answer_sent_ from it. This records queue acceptance, not completion of the asynchronous write.

A user's stream failed with "The GeForce NOW rig could not be reached". The logs show the server stopped responding right after the SDP answer was sent. It never acknowledged the answer or the candidates, never trickled its media candidate, and sent no more heartbeats. By the time the stream ended the signaling socket had closed. Without the server's candidate, all 12 ICE pairs failed.
The WebSocket client already records why it closed (close frame code, remote EOF, receive or send error, send timeout), but nothing wrote that reason to the log. The session now logs one
SIGNAL disconnectedline the first time signaling goes from connected to disconnected. The line includes the reason, the time since the session started, the received message count, and whether the answer was sent and a remote candidate arrived. That tells a server-side close apart from a local send failure in the next report.The streaming host suite (95 checks) passes, and the Switch NRO builds and contains all 51 embedded resources.
