// Chosen is the provider somebody named for a provision: the module, and the node it runs on. Both,
// always (novox/hq #258) — a provision comes from a module, and the same module on two machines is
// two answers, so neither half alone says which. Module is empty only on a record made before this
// was asked, and such a record is honoured exactly as long as it is unambiguous.
