ElevenLabs sends all JSON messages as binary WS frames, not text frames. The OnRawMessage callback receives them; we were logging them as warnings and discarding the data entirely — causing no events to fire at all. Fix: accumulate binary frame fragments (BytesRemaining > 0 = more coming), reassemble into a complete buffer, decode as UTF-8 JSON string, then route through the existing OnWsMessage text handler unchanged. Added BinaryFrameBuffer (TArray<uint8>) to proxy header for accumulation. Compiles cleanly on UE 5.5 Win64. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
