# Anatomy fit regression coordinates

`anatomy-fit.json` records the pre-fit positions at the released vertex ordering
for six representative BodyParts3D muscles. The first faulty fit was invertible
per vertex (a weighted affine transform), so these coordinates were recovered
from that release without another decimation or topology change. The corrected
export is independently rebuilt from the original OBJ archive. These fixtures
let ordinary Node tests detect the original stretched edges without Blender or
a downloaded atlas. They are geometric regressions, not clinical validation.
