Hourly sweep marks expired Free instances lapsed and sends at most one
notice per instance per pass, most urgent first, recorded on the document
so a restart cannot re-send.
Deletion warnings are suppressed when the reaper is off. Promising a
deletion that will never happen is a lie, and a scarier one than silence.
