2
3Who keeps the durable copies of a job item's payload before its result is sent: the member that ran
4it, the leader, then the next members after it (in id order, wrapping) that are alive, up to
5`COPIES` (3) distinct members. A member whose store refused (full) is skipped, but the leader never
6is. With no leader there is no answer. A committed payload therefore survives the loss of any two
7members, the leader among them. Also the resend times of pushes and fetches, and `PARKED_MAX`.
8Header-only and freestanding.
