nx_skull_canon_gate.nx -- THE GENERATED SKULL AGAINST THE SCANNED ORACLE, LANDMARK BY LANDMARK (anatomy AN17, 2026-09-18). ACCEPT RULE, PRE-DECLARED BEFORE THE FIRST MEASUREMENT: (i) ONE locator (nx_tissuefield_lib.tfl_locate, composed through nx_skull_canon_lib) locates the craniometric landmark set on BOTH the oracle (knowledge/skull.nxmesh, BodyParts3D, CC BY-SA 2.1 Japan -- the RULER, never the product) and the generated skull (argv[1], else ./nx_skullsdf.elf run from the estate root at sex 0, robust 500, 2 mm cells: the tune's own parameters, because the oracle is one adult male). A generated skull the locator refuses is a RED, never a SKIP -- that IS the substrate defect; (ii) every quantity is compared relative to the nasion in each mesh's own upright frame (the oracle's file frame is z-up and is read as such) and HOLDS when |ours - oracle| <= band, band = the locator's re-location noise on the oracle plus on ours (half-edge shift, one-edge pitch, one-edge yaw, floored at half a mesh edge) plus the oracle's bilateral asymmetry where the quantity is paired. Nothing is typed; (iii) the classes: chin depth (pogonion - glabella, sagittal), nasal aperture position, height, width and depth, orbit spacing, height, width and depth, bizygomatic breadth, bigonial breadth, prosthion depth and upper face height, and THE SUBSTRATE THIRDS TOOTH MOVED HERE FROM nx_skullskin_gate (its header (iii): the skin's middle third equals its lower third within the tissue table's spread). On the SKULL the same spans are glabella->nasospinale and nasospinale->gnathion and the bar is the ORACLE's own imbalance, because a real skull's bony lower third is longer than its middle third and a canon of equal thirds would convict the ruler; (iv) neg-control-oracle-reads-inside-its-own-bands: two HELD-OUT rigid perturbations of the oracle (a negative half-edge shift, a one-edge roll) must read inside the bands built from the other three -- a band that only fits the perturbations it was read from is not a band; neg-control-a-planted-49mm-chin-shift-reads-outside: the oracle's own record with its pogonion moved 49 mm forward (the muzzle measured on the generated skull on 2026-09-18) must read OUTSIDE the chin band; (v) the alignment is a TRANSLATION to the nasion and no rotation (both meshes declare y up, z anterior; a rotation derived from the vault absorbed the generator's own vault defect, measured 2026-09-18), and the rotation it refuses to apply is itself a tooth: the glabella-opisthocranion chord's pitch. Every value is emitted (gv_kv / gv_check_near) for an outside adjudicator; the wall time is printed (the heavy roster's budget is read there).
