How it ended
One of five outcomes — accepted, error, invalid, lost, timeout — the second half of the classification.
In detail
Short and consequential. accepted is a delivery; error a refusal with a code; timeout a receiver that stopped answering; lost a connection that vanished; invalid something wrong with the message itself. The distinction between error and timeout matters for reputation work: a refusal is a judgement about the sender, a timeout usually is not.
