Every handed-away branch is the only one: world.assigned is the placement, the pair comparison and its conditions go, the
lease and assignments buckets are no longer opened, watched or declared, and a proposal of any kind is taken.
Tests: the pair-comparison test and the controller-composition record-ask test are replaced by one placement test; the
rest are edited to place their modules instead of assigning them.
