nx_gltf_inventory_candidate_t180.nx

nx_gltf2mesh.nx -- GLB/VRM -> NXMSH2 mesh-oracle extractor (debt 1785902685, the D2 POSITION slice). The whole bench suite (nx_bodybench / nx_twinbench / nx_curvebench / nx_facemark) judges .nxmesh oracles, but NO organ could turn a donor .glb/.vrm into one -- donor FORM was invisible to every instrument we own (operator 2026-08-05: the T2 being is still a clay blob because the ruler only reads skeletons). This organ reads ONLY what a form oracle needs: every TRIANGLES primitive's POSITION + indices (u16 AND u32, tight or strided bufferViews), multi-mesh multi-primitive concat. FAIL-CLOSED at every offset (D1): a file this cannot parse REFUSES with a named reason and a nonzero exit -- never a segfault, never a silent empty mesh (zero accepted tris = REFUSAL). Morph-target POSITIONs are excluded by scoping the attribute scan to the primitive's attributes{}. Skinned bind-pose positions are model-space per the glTF spec (node transforms ignored for skinned meshes); VRM avatars are skinned throughout -- reported in the status line, never silent. nx_gltf2mesh <in.glb|.vrm> <out.nxmesh> | nx_gltf2mesh selftest nx_gltf2mesh <in.glb|.vrm> <out.nxa> -- R22 RIG-CARRYING INGEST (charsim.plan, contract symbol g2_skin_weights): when the OUTPUT name ends in .nxa the donor's skin is carried into the estate's rig container NXANIM01 -- VERT (shared vertex table, mm) / TRIS (index triples) / SKEL (one record per skins[].joints entry: parent, bind position from inverseBindMatrices, identity quat) / SKIN (per vertex four joint indices + four Q12 weights summing to EXACTLY 4096). That layout is the one nx_nxa_skin WRITES, nx_nxa_check ENFORCES and nx_nxa_rig_emit DIVIDES BY -- read from those three, never invented here. NXMSH2 structurally cannot carry a rig (84-byte triangle soup, no joint section, 17 consumers hardcode that arithmetic), which is why the round trip measured 2026-08-22 lost every named part of every rigged donor. An unskinned donor asked for .nxa is REFUSED by name; the .nxmesh path is byte-identical. license_tier: ORIGINAL expect_exit: 0
