nx_cdmap_pixjudge_gate.nx -- referee for the position map's PIXEL REFEREE (datavis DV2, 2026-09-15). Hand-built figures are drawn as ink through the sovereign font engine and the pixel critic is held to what a reader would see: a pristine figure reads clean; a PLANTED FONT-METRIC DRIFT -- two runs of wide glyphs reserved by the heuristic width and placed just past that reserve, so the self-grade's boxes are apart while the real ink overlaps -- must be caught by the pixel ruler AND missed by the box ruler on the same bytes (the DV2 done-rule); a label on ANOTHER player's mark is a defect while a label on its OWN mark is not; ink that leaves the plot frame is OFF; the agreement call is bound to the published number both ways; a missing face is a NAMED refusal, never a zero vector; and, when the live search page is on disk, the served figure's pixel grade is compared with the grade it published (an optional witness announced through gv_kv, never gv_need, so an absent page cannot SKIP the gate forever on one host). The face IS the subject's substrate, so its absence is gv_need: without a face nothing here measures anything. license_tier: ORIGINAL
