The behaviour profile read the newest 2000 rows of the shared facts table and
then discarded everything that was not kind=self, so the length of the window
was set by the noisiest writer. mavpoll writes a wg_handshake row every time a
peer rehandshakes, about every two minutes per peer, which is enough to reduce
2000 rows to under three days. A weekday habit needs two distinct Tuesdays, so
that window can never hold one, and she answered that she knows no habits on a
store holding a year of taps.
RecentActiveFactsByKind filters kind in SQL, and also drops rows a later row
voids along with the void marker itself. The old read counted both a retracted
tap and its retraction, so a fact he explicitly took back still shaped what she
said he usually does. A correction still counts, because a correction is a value
he stands behind.
Found in review of #59.
