# G44 -- A card names only what the knowledge base contains, and carries the banked twin

A card may not name a lever the knowledge base does not contain by the words on the card. The twin scan runs over the whole
world, not the card's binary; a banked twin beats an open one and goes on the card as the seed. The pack is placed where
the agent is told to read it.
