Detailed Description

the head of every message on a service connection, its data behind it: a request, its reply or the service's broadcast

Every side reads a message as untrusted bytes: trivial types alone, byte identical in every process - 32 and 64 bit, any architecture -, its sizes checked before anything of it is read (check()).
