Design 47's last milestones: the keeper, self-check, healers, hand-acts, provisioner, vault, artifact sweep, disk readings, credential forms (issues 774, 1952, 1953, 1954, 1955)

One commit with exactly the tree of the reviewed head 35b4509c0a, on main 12c2574c9d, so two compiled programs added and removed on the branch leave no trace in history (issue 1577).
