move-in never replaces a value the vault holds, so where the controller made an own secret anew after the move, the
new value runs while the vault keeps the first. The verb own-take-running takes it from the node-engine of the machine
it is for, keeps the replaced value as the previous generation, raises the generation and says own-replaced without a
value; own_drift lists every own secret a node's shadow answer says another value of, mesh-wide. The module needs the
mesh-sdk head of fix/1126-seed-same-own-resync (delivery.OwnValuesDiffer, the seat's verb).
