Function below_whole_floor 

fn below_whole_floor(memory: &Memory, key: &str, c: u64) -> bool

Whether a record of an element of a list format 1 sent whole (pinned sites, words, days off, routines, task kinds, lighter days) comes at or below the clock of a whole list that took that element out here (Floor::removed), the list not holding it since. Passed over, so that an element taken out before the switch never comes back, as when a device restates its old entries in a new round (share-own-cut). An element no whole list here ever held (added in format 2 elsewhere, its record waiting here) is never passed over: a list that did not know it did not take it out.
