   function `AnswerSeat` takes is written once, in mesh-sdk's `seatlist` (the definition of a seat from the list a part
   follows; none until the list is read, none for a seat it does not hold), and every holder passes it. A part that
   serves a seat verb follows the seat list with its grant, as the pipeline runner and mesh-recovery now do.

+- **A-279** (A-236, §715; principles 1 and 7; corrected three times, this form stands) A group member's `base` is its
+  pull request's base branch as the seat `git` says it in `pull-updated` (which carries `Base`): the gate consumes that
+  event and keeps the base on the pull request's `MergePull` in its state `merges`, the entry the Approve makes; the
+  verb `groups` answers a group with no record yet from `merges`, and the take-in copies the base onto the record's
+  `RecordGroup.Pulls` when it opens the record. No new state; the take-in's branch never stands in for it.
