-Data-channel failures are treated as control-plane failures, not proof that RTP audio has stopped. When an open channel reports a non-fatal error, the client requests a fresh voice-state snapshot over that same channel. When the channel closes or cannot carry the resync request, the peer manager waits a short grace period so any still-flowing audio is not interrupted by a transient event. If the `RTCPeerConnection` is still connected after that grace period, the elected initiator replaces only the data channel in-place and preserves the media transport. Full peer recreation is reserved for cases where the media transport is no longer connected or the in-place control-channel repair fails.
+Data-channel failures are treated as control-plane failures. When an open channel reports a non-fatal error, the client requests a fresh voice-state snapshot over that same channel. When the channel is already closed there is no recovery on it, so the peer manager acts immediately: the deterministic initiator renegotiates a new `RTCDataChannel` on the existing `RTCPeerConnection` (preserving audio/video transport), the non-initiator briefly waits for that replacement and then forces a full peer rebuild if it does not arrive, and a peer whose `RTCPeerConnection` is no longer in `connected` state is recreated immediately through the normal deterministic reconnect path. A closing-but-not-yet-closed channel still waits a short grace period in case the underlying transport flips back. Either way, the rebuild heals chat, state sync, voice, camera, and screen-share transport together instead of preserving a media connection whose control channel can no longer coordinate peer state.
