relay

Sends command, admitted here for an aggregate of another service's context (a peer's), to its context's command topic through relay, and emits a result for each hop of its wait plan as it is reached, as the topic router's commands do: ACCEPTED once the broker acknowledged it, durable from then on; the target's intake executes it and signals its COMMITTED result here. function names the command in the results this node makes. The command's plan has only ACCEPTED and COMMITTED hops of its context: admission refuses any other.
