Every check of `abort' so far was of it being refused while the program runs. The accepted path -- the one that ends a program -- was code that had never run and answered `ok'. So the break block breaks its program once more, by installing a `step' that errors into the loop that calls it, and takes the exit: the daemon owns the program's lifetime, so no `close' is sent and the daemon coming down on its own is the assertion. And `restart' refuses a name with a control character in it. The agent's contract is one line per request; a newline in a name is a second request smuggled into the first. `completing-read' with require-match cannot produce one, but the guarantee belongs to the end holding the socket, and an editor is not the only thing that can speak to it.
