sub_822F9498 (the unit-definition loader, called only from sub_821A6CF0) is the only function referencing the AA_/AV_ name strings. Mapping each name to the stfs that follows gives an exact interleave: AV_ at X, AA_ at X+8, for all five axes -- PitchPlus 196/204, PitchMinus 212/220, Yaw 228/236, Roll 244/252, AxisMode 320/328. A selector is an offset of 0 or 8, not two lookups. The 20 strings exist twice in the image; the first block is referenced by nothing. Data control: the ten suffixes match exactly between families. The selection stays a reading: functions loading two or more of 196/204/320/328 number 39 image-wide, and only two are call-graph-reachable from the loader.
