nx_xps_gate.nx

nx_xps_gate.nx -- THE XPS READER GATE (/compare/modding MD2, 2026-09-06). One small rigged model (two bones, one mesh, four vertices, two triangles, one texture) is written at runtime under /tmp/nx_xps_gate/ in THREE spellings the reference readers define: the ascii dialect, the binary dialect at version 3.15 (variable weight counts, no tangents) and the binary dialect at version 1.12 (fixed four weights, a tangent per uv layer). All three must read to BYTE-IDENTICAL NXANIM01 -- the cross-dialect identity is the tooth a reader written from memory cannot pass, because the version-gated tangent and weight-count fields shift every byte after them. The container is read back through nx_nxa.nx's own nxa_find (an independent reader that verifies the TOC and payload checksums), the served pose player is the second witness (zero_weight_verts=0), a truncated binary is refused by name, an unnormalised weight line is fixed and counted, and the declared scale is proven to move the numbers. usage: nx_xps_gate (no args) license_tier: ORIGINAL No hw writes (Rule 26). expect_exit: 0
