A station's instances as the wire spells them — the one place a mold turns "which addresses
exist" into "which ids exist", so no mold re-derives the canonical spelling of an enumeration.
undefined when the station cannot enumerate, and that stays distinct from the empty list all
the way out to ConsoleResource.instances: "I hold nothing" and "do not ask me" are different
answers, and a snapshot that flattened them would report an unaskable entity as empty.
