1// nx_faceanat_mesh_gate.nx -- ★B-R3 / the DAZ-EXCEED RUNG: EMIT our own base MESH from the VALIDATED anatomical 2// field (operator 2026-07-08: "our own base mesh better than DAZ ... toward photoreal VR"). DAZ ships a 3// hand-authored base mesh; we GENERATE one from canon proportions + tissue-depth (nx_faceanat) via sovereign 4// surface-nets (nx_meshgen) -> a real watertight triangle mesh -> glTF (the VR/VRM interchange format). The 5// generative path EXCEEDS the authored one on: adjustability (any proportion/depth = a number), resolution 6// (regenerate denser), and sovereignty (zero DAZ/Blender). 7// T1 the anatomical field MESHES: verts + tris emitted in a base-mesh range 8// T2 ★WATERTIGHT (the DAZ-quality bar): closed genus-0 manifold => Euler V - E + F = 2, and for a triangle mesh 9// E = 3F/2, so V = F/2 + 2. Assert the emitted mesh satisfies it within a small topology tolerance. 10// T3 it's a real 3D HEAD: the AABB spans all three axes (not a flat sheet), width ~ height ballpark 11// T4 exports a VALID glTF (.glb magic 'glTF', nonzero length) = VR/VRM-loadable + determinism 12// license_tier: ORIGINAL expect_exit: 0 13import "nx_syscalls.nx" 14import "nx_faceanat.nx" 15import "nx_meshgen.nx" 16import "nx_gltf_export.nx" 17import "nx_gate_verdict.nx" 18 19func hw(s: *u8) -> i64 { var n: i64=0;
