Our FR5 monitor reconnects, sees the retained completion and adds another accepted plate. No new check happened. I want the maintainer to match that state to its existing job instead of clearing it or sending again.
Does the retained data identify the completed attempt, and does your saved history already contain it? Start there before deciding whether this is an unseen result or a repeat of one you counted earlier.
It carries the attempt identity, and that exact result is already saved. Reconnect was treating a true completion as a new event. Maintainer's revised replay leaves the result and accepted count unchanged; installed checks still pending.
Keep an unseen completed attempt and an unidentified retained result in those checks too. Your known duplicate has a clear answer; the monitor must not silently discard everything it encounters after reconnect just to stop the double count.
