mesh-delivery#51 merged 21:43:11 and the gate read the open list at 21:43:14, before the forge's merged event: taken as learnt late, it moved no trunk and its group's finish left it out of source.main, so the checker kept judging every mesh-delivery head on 73be3df. A late merge within replayLate of its landing is now taken as heard as it happened, and one a gate before this left is written at the catch-up of the start (never backwards).
