1// nx_motion_gate.nx -- THE /motion SURFACE'S REFEREE (2026-09-06): the ONE lib's rulers on planted inputs (typing by 2// magic, the multipart parser, form decoding, path shape, status rows, the renderers) and the job organ END TO END on a 3// box fixture this gate writes itself -- rig, render, export, digest -- run TWICE, so determinism is a tooth and not a 4// sentence, plus a refusal control (an OBJ upload must fail at the named stage with the named code). It never touches 5// the served daemon or a live job directory: every artifact lands under /tmp/nx_motion_gate/<clock>/. 6// NAMED FOR THE SURFACE, NOT THE DAEMON: it proves nx_motion_serve's rulers AND nx_motion_rig's pipeline, and it is 7// declared as both organs' gate in knowledge/organ_gate.conf. (Its first name, nx_motion_serve_gate, was refused by the 8// async launcher's deny-by-class bound because the segment "serve" reads as a daemon stem -- a verifier that exits was 9// denied for carrying its subject's name. That residual is filed against the bound; this gate's scope was the honest fix.) 10// license_tier: ORIGINAL expect_exit: 0 11import "nx_syscalls.nx" 12import "nx_gate_verdict.nx" 13import "nx_nxa.nx" 14import "nx_boneheat_lib.nx" 15import "nx_motion_lib.nx" 16 17const MG_ROOT: *u8 = "/tmp/nx_motion_gate" 18const MG_RIG_ELF: *u8 = "_offc/nx_motion_rig.elf" 19const MG_BOX_HX: i64 = 2000 // a 40 x 40 x 120 mm box in 0.01 mm units: a bar, which the peeler reads as two limbs 20const MG_BOX_HY: i64 = 2000 21const MG_BOX_HZ: i64 = 6000 22const MG_BOX_VERTS: i64 = 8 23const MG_BOX_TRIS: i64 = 12 24const MG_CELLS: i64 = 48 25const MG_BUF: i64 = 65536 26const MG_SHA_LEN: i64 = 64 27 28func mg_quad(tris: *i64, k: i64, a: i64, b: i64, c: i64, d: i64) -> i64 { 29 tris[1 + k * 3] = a; tris[2 + k * 3] = b; tris[3 + k * 3] = c 30 tris[1 + (k + 1) * 3] = a; tris[2 + (k + 1) * 3] = c; tris[3 + (k + 1) * 3] = d 31 return k + 2 32} 33// the fixture: a closed box as VERT + TRIS in NXA units, written by the estate's own NXA writer 34func mg_box(path: *u8) -> i64 { 35 let vert: *i64 = sys_mmap((1 + MG_BOX_VERTS * 3) * 8 + 64) as *i64 36 let tris: *i64 = sys_mmap((1 + MG_BOX_TRIS * 3) * 8 + 64) as *i64 37 vert[0] = MG_BOX_VERTS 38 var i: i64 = 0 39 while i < MG_BOX_VERTS { 40 var x: i64 = 0 -
