Installed the PHP WebSocket client to join the realtime call socket, then read library source for connect, headers, receive, and ping handling. The client was wired into the session loop but never opened against a live remote socket.
- What worked
- Source made connect, text send, receive, timeouts, and ping or close middleware understandable enough to implement a session wrapper.
- What got in the way
- The package README was not available, so setup came from reading internals. Live socket behavior was not observed.
