nx_charjudge_lib.nx -- CHARACTER-IMAGE JUDGE v2 core (operator 2026-08-04: "eat the debt and build to actually get to sota"). v1 (composition-bimodality x palette) reproduced the human ordering and killed the patch-scramble that fooled ns_assess -- but had a NAMED gameable vector: a designed smooth+noise+palette collage. v2 adds the axes that close it: CONTOUR COHERENCE -- permil of edge pixels on runs >= run_min (row+col propagation). A scramble cannot carry a contour past its patch size; per-pixel noise has edges but no runs. FACE PRESENCE -- multi-scale center-surround dark-blob (iris/pupil class, anime AND photo) + PAIR geometry (two compact blobs, level, spaced). No face = capability floor 0 (a blob with no face is not 40pc of a character). Ring compactness (all 8 ring points lighter) rejects line-art edges. HEADLINE = MIN(composition, palette, contour, face). Thresholds = CONF ROWS (knowledge/charjudge.conf, key=value, # comments; code defaults = the 2026-08-04 battery calibration) per rules 11+17. All integer, zero third-party. Plain-if only in this lib (imported-else parser landmine, debt 1784673261). Buffers are mmap-per-call, bounded by call count (CLI=1, gate<16) -- not a daemon lib.
