 1// Realm cointest is a throwaway deployment-validation helper for the
 2// vault realm. It creates the two out-of-band conditions the vault's
 3// surplus machinery must handle — a direct bank send of ugnot and a
 4// foreign denomination — and exercises the vault's realm-caller
 5// rejection. Not part of the product; safe to abandon after validation.
