mesh-sdk now carries the hand acts that warranted a node's rotations as NodeLogin.Acts (ADR 0583 §2), so the vault's
own `acts` field beside the codec is gone: a used act is refused from the key's Acts, and a key written without them
keeps the ones recorded. The seat's tunnel takes all five fields; the wire table refuses an issue missing the machine's
tunnel key or the range as well. Built against mesh-sdk 4224665; mesh-vault stays at 134 unit tests.
