0x800F3DC0 (88 B) — a ONE-WORD sibling of the matched 0x800F3E18, found by worker E via sf3_family at ratio 1.000 and confirmed by raw-word diff: identical in all 22 words except the COP2 command field (0x4B70000C vs 0x4B78000C). The route was one copy, two renames and one field change; every __asm__ and register binding carried over untouched. 166 records it, and notes it is the MIRROR of finding 161: on 0x800F3E18 the field 0x178000c was the WRONG answer (one byte off, 0x170000c correct); on 0x800F3DC0 0x178000c IS correct. A count tells you a field is COMMON, not that it is right -- and a ratio-1.000 sibling is the cheapest place to learn which one a row wants. When the family tool reports one, diff the raw words FIRST.
