The transform WebSocket accepted any model and opened its frame-based RPC. Any-to-any models use a different stream contract, so liquid-audio failed with an unimplemented RPC after the handshake.
Reject incompatible model use cases before loading the backend. Direct realtime-audio callers to the OpenAI Realtime API.
