The seat gains item-started and item-ended on <event>.<node>.<module>.<item>, kept last per subject for 7 days,
each with at, and item-ended with outcome (done, failed or put-off), the restore's act it gave way to and an
error, so the recovery module and the backup holder each read the other's start and never overlap. The seat is
of the seat-list grain: nothing is generated and its fixtures are not read, so mesh-sdk's definition reader and
its bootstrapped copy of this file are what read it.
