```


Start by reading maga_transformer/distribute/worker_info.py, especially WorkerInfo.from_env at the socket.gethostbyname call, and its import path from maga_transformer/start_server.py. Reproduce the reported startup environment and determine the expected behavior when the hostname has no address; done means startup handles or clearly reports that condition without the traceback.
