nx_faceprofile_gate.nx -- ★DEPTH-AXIS fit (B-R2b): a FRONTAL reference can't see depth; the 90-degree PROFILE reference (elara_face_profile.jpg, CUDA-generated) is the ONLY view that measures nose/brow/chin PROJECTION. We know OUR geometry's z EXACTLY (the part table), so we only extract the reference's profile silhouette and compare PROJECTION RATIOS (how far brow/lip recede behind the nose, scale-invariant). This calibrates the tissue-depth relief on the axis it actually controls. T1 the reference profile silhouette extracts (a real face outline: nose is the most-projected point) T2 ★DEPTH FIT: our faceanat's brow-recession and lip-recession ratios (from the part-table z) land in the reference's measured ballpark -- the inside-out depth is grounded in the profile, not guessed T3 the anatomical face BEATS a flat-depth straw-man (nose-not-most-projected) on the same ratio metric (neg-control: proves the metric discriminates real profile shape) license_tier: ORIGINAL expect_exit: 0
