// Settings spec rev 11 §4.3a: a landing move carries the build state with
// the replica. The legacy round mirrors the whole hibernate prefix to
// moves/<host>/, and promoteStagedReplica copies every staged object over
// the own prefix, build-state.json included. This pins today's behaviour:
// a keep filter added to the promotion later must not drop it.
