Worker E's 0x8005E17C and 0x8002FAB8; worker F's first two claims 0x800FBE84 (216 B, FIRST SPELLING with worker A's derivation) and 0x80026274 (108 B). 170 generalises the argument-evidence levers (157/164) into a mechanism: a redundant ENTRY-BLOCK copy of an argument means that value is still live at a call whose argument setup CLOBBERS that same register. The copy is materialised in the entry block because the tie to a0's home is illegal. The test that nailed it: the same body with a 2-arg call is 104 B LENGTH-MISMATCH; with the 3-arg call it is 108/0. Two prior corpus instances had the copy AT the call; this is the hoisted-to-entry variant. 171: worker F confirmed EXHAUSTIVELY that the constant-division divisor is unique per magic -- (n*M)>>(32+s) == n/D has exactly one D. So finding 67's identity is not an approximation.
