about

nx_stl_write_mesh_test.nx -- KAT gate: the GENERAL mesh exporter writes an ARBITRARY NxMesh to binary STL that the existing reader/slicer pipeline accepts. Proves (a) cube parity with the hardcoded writer, (b) Q14->f32->Q14 units survive EXACTLY end-to-end (10mm corner comes back as 163840 Q14), (c) a NON-cube mesh (quad) also round-trips -> the seam is general, not cube-special. expect_exit: 0.
