about

nx_spec_gate.nx -- GATE for CAP-PBR rung-2 (Blinn-Phong specular, mr_face_specular + mr_pow_q14 over render_core): the glossy highlight from the COMPUTED (deformable) face normal + the half-vector. Proves with HARD numbers: (T1) perfect mirror config -> full highlight == Q, (T2) grazing -> 0, (T3 MEASURED) higher shininess NARROWS the highlight (dimmer at a fixed off-angle), (T4 MEASURED) tilting the view off the mirror angle dims it MONOTONICALLY, (T5 teeth) back-facing + degenerate -> 0 (no div0/no hallucinated light), (T6) integer pow correct. Q14 no-float. expect_exit: 0
