Worker A calibrated sf3_family by checking two 0.97 entries and finding neither shared its sibling's body. I have now confirmed that on eight candidates by raw-word diff, which is the decisive test: 0x8006EBA0 vs 0x80028CE0 differs in 60 of 61 words; 0x800FFFEC vs 0x8007E8B8 in 18 of 19; 0x8005E17C vs 0x800FB54C in 25 of 26. Contrast the genuine sibling 0x800F3DC0 vs 0x800F3E18: 1 of 22 words. So a high cosine with ratio 1.00 is NOT evidence of a shared body -- at 0.96-0.99 the histogram matches common IDIOMS. The useful band is ratio 1.000 AND a near-zero raw-word diff. Tool bug fixed: sf3_family did not exclude already-claimed rows, so its top hit was a row matching ITSELF. The registry is now the authority and claimed rows are skipped.
