Development record
2026-10-16 — A drain renews its lane's lease every move (facilitator-on-delegation, drain-many-accounts): every drain move, waiting or not, renews its in-progress lane's reservation at half its lease before its window gate, independent of the lane's progress; and the land stage checks the reservation before its push as well as at arming, handing the lane back at once when the hold is now another's, so a lapsed lease never becomes a duplicate pull request (grounds: lease keep-alives as Chubby and etcd keep them, and fencing before a write; iss-2610161015393523).

- iss-2610161015393523A drain's in-progress lane is renewed only when its own step or receipt runs, so if the host pauses the lane for more than the two-hour default lease another account takes the reservation over five minutes after expiry and works the same issue; the land fence runs only at arming, after the push and the pull request, so the duplicate becomes a public pull request.
