Gate keeps the merge's six states and asks the controller nothing (issue 1946, R6-C1, C2, C4)

Release 6 deletes the plans: the walk half of the holder, the controller port, the carry-over of the former module and the verbs times, what-if, release, stop and retire-history go; the table holds proposed, ready, rejected, merged, held and closed; the delivery's status and view name the source revision the merge moved.
