nx_faceanat_mesh_gate.nx -- ★B-R3 / the DAZ-EXCEED RUNG: EMIT our own base MESH from the VALIDATED anatomical field (operator 2026-07-08: "our own base mesh better than DAZ ... toward photoreal VR"). DAZ ships a hand-authored base mesh; we GENERATE one from canon proportions + tissue-depth (nx_faceanat) via sovereign surface-nets (nx_meshgen) -> a real watertight triangle mesh -> glTF (the VR/VRM interchange format). The generative path EXCEEDS the authored one on: adjustability (any proportion/depth = a number), resolution (regenerate denser), and sovereignty (zero DAZ/Blender). T1 the anatomical field MESHES: verts + tris emitted in a base-mesh range T2 ★WATERTIGHT (the DAZ-quality bar): closed genus-0 manifold => Euler V - E + F = 2, and for a triangle mesh E = 3F/2, so V = F/2 + 2. Assert the emitted mesh satisfies it within a small topology tolerance. T3 it's a real 3D HEAD: the AABB spans all three axes (not a flat sheet), width ~ height ballpark T4 exports a VALID glTF (.glb magic 'glTF', nonzero length) = VR/VRM-loadable + determinism license_tier: ORIGINAL expect_exit: 0
