nx_profile_fit.nx

nx_profile_fit.nx -- ★MEASURED CROSS-SECTION PROFILES FROM A REAL ANATOMICAL REFERENCE. This is the Infinigen method, done sovereignly: their creature lofting threads NURBS surfaces through profile sections taken from REAL references (nurbs_data). Ours threaded ELLIPSES -- and a human cross section is not an ellipse (flat back, spinal furrow, sternal hollow, deltoid shelf, iliac flare). This organ SLICES an oracle mesh at every station height, clusters each slice into torso / arm / leg / head, fits the section's bounding ellipse, and emits the DIMENSIONLESS deviation of the real outline from that ellipse as a per-angle ratio. ★WHAT IS AND IS NOT TAKEN FROM THE ORACLE: only the SHAPE PRIOR (a per-mille ratio per angle, 1000 = on the ellipse). Every SIZE stays procedural -- the generator still decides stature, breadth, build and dimorphism. So this cannot become "ship the scanned body": it is a measured shape rule the emitter applies to whatever body the rule engine asks for, exactly as Infinigen applies profiles from refs to a genome. Oracle provenance/licence is written into the emitted file header by the caller's manifest. nx_profile_fit <oracle.nxmesh> <out.dat> [step_permil] [canon_out.dat] [part_id] ORGAN MODE: supply part_id and the oracle is declared to BE that single part -- no band gate, no limb clustering. Absent it, the body path is unchanged. license_tier: ORIGINAL expect_exit: 0
