nx_stl_to_gcode_real_test.nx -- HARD REAL TEST end-to-end: hand-constructed binary STL bytes -> nx_stl_load_binary -> nx_slice_pipe_run_v2 -> G-code text with supports + perimeters. Operator directive 2026-05-20: "lets get to some hard real testing" Earlier hard real test (nx_slice_pipe_v2_real) used the in-memory nx_mesh_make_tetrahedron helper -- already pre-converted Q14 vertices, no STL bytes touched. THIS test exercises the COMPLETE real-byte path: 1. Hand-build binary STL byte stream for a 10mm tetrahedron 2. Pass raw bytes through nx_stl_load_binary (real parser, real IEEE 754 float32 -> Q14 conversion via nx_fp32_bytes_to_q14) 3. Feed the parsed mesh into nx_slice_pipe_run_v2 4. Assert structural properties of emitted G-code This proves: external-format bytes -> substrate slicer -> G-code, the workflow an operator would actually use loading a Christus STL. expect_exit: 0 license_tier: ORIGINAL
