2
3The job table's leadership ids. A lid is the fleet term in its high 24 bits and a count below it.
4`mj_lid_next` picks one above every leadership a member has persisted, so a later leadership's lid
5is always larger, even within one term (a restarted coordinator, a leader that leads again), and
6never comes from a clock (review finding 10). `mj_lease_base` is the first lease id of a leadership,
7so two leaderships' leases never share an id. Header-only and freestanding.
