Remarks

This is the half of a folder's status that survives a restart, and the half that separates a folder with nothing left to fetch from one that has been repeating the same batch. A run that fails before committing leaves the instant where it was, so an alias whose progress last moved a day ago while its runs keep ending is stuck rather than quiet.

An alias can have been bound to several remote folders over time and each binding keeps progress of its own. What is reported is the binding that moved most recently, because the older ones describe a UID space the mail server has already renumbered away from.
