The controller's placement-export is no longer called, its answer reader, the seed and the hand-back flow of the holder are
removed, and a seed or hand-back proposal a previous process left open ends at its next pass.
Tests: the adopt, hand-back and seed cases of the seat's verb test and of Propose are replaced by one gone-case; the export
reader's table and the seed test go.
