B's family-target scan paid off a 3rd time: 0x80057B84 = the family's 4th
member, matched on the 2nd attempt with two levers — (1) branch-vs-
branchless discriminator (how many distinct values are selected decides

image of the usual named-locals lever). Two negatives recorded
(0x800179E0 guard polarity, 0x800C1E54 dead local). Gate MATCH whole-
binary SHA-1 e173426c157384ebf1b6caf8c6fea18a85a14af9.
