The meter reads the week only while a lease is held or was asked for less
than a staleness period ago. A held swarm brake stops the units, so a braked
or quiet swarm spends nothing; the brake path, the duplicate brake type, the
store read, the frozen store fixture and the chrono serde feature are gone.
A request is noted by the QuotaCell for as long as it lives (a 4 h lease
counts) and wakes the meter. A lease asked of a metered cell with no weekly
reading (every restart) waits up to 10 s for the meter's first read before it
is lent, so it is not lent unobserved for its whole life.
A call is a miss only if it left the reading unrefreshed: a rejected turn
that reports its windows and then errors is no miss, so a rejected reading is
kept fresh every period. The failure kind is logged on change.
