The captured SDK (testdata/beside, conformance/events) is taken again at the pinned commit, as CAPTURED
says. The controller's mirror of MoveSecretAnswer gains `superseded` (mesh-host b9c24a7): the vault holds
another value, the live one, and the machine's older value is not moved and not asked again. The field
test names it. A superseded row is still counted with the moved ones: counting it apart needs a field and
its words in nodeMove, more than the one line asked.
