Start with the `tidevice wdaproxy` command and the Tornado `tcpserver.py` callback shown in the traceback, then reproduce the failure by requesting `http://localhost:8200/status`. Done means the callback no longer raises the assertion or unawaited-coroutine warning and the status request can reach the device.
