Development record

The implement loop's renewal takes its term from the reservation tip as last seen in the remote-tracking ref (claim.View), not the tip claim.Reserve fetches fresh; in a single-branch or depth-limited clone, or one with a narrowed fetch refspec, a push does not update that ref, so a stale two-hour tip can make a drain push a two-hour renewal over the fence's day-long tip and lapse the hold.
