Issue 258's fix let a mesh seat's holder elsewhere answer before this machine's own provider. Right for the resolver, which any provider answers alike; for the store's seat it re-bound every database consumer on a machine running its own store to the holder on another, each was given a fresh, empty database there, and nothing said so for twenty hours. - An offer says whether it keeps its consumers' data (`keeps-consumer-data`); unsaid, a provider that grants each consumer a credential does. For such a provision the seat's holder no longer overrules a provider beside the consumer; a pin still does. - Where each such consumer was sent is recorded (migration 0071). A resolution that would bind it elsewhere keeps the recorded provider and says the move; one whose provider is gone is refused, never answered by another. - A push says a kept move and raises it as an urgent condition at once; the self-check's D12 raises it every run, with a pinned move not yet sent as a warning and any unasked move as urgent.
