nx_cdmap_referee.nx

nx_cdmap_referee.nx -- the position map's SECOND RULER as a program (datavis DV2a, 2026-09-15). Reads an emitted compare page and its api.json, re-derives the 2D cut's readability grade from the SVG alone (the heuristic critic must REPRODUCE what the page printed), then re-measures every label with real TrueType advances from a real sans face and grades again. usage: nx_cdmap_referee <index.html> <api.json> <regular.ttf> <bold.ttf> exit 0 AGREE the heuristic critic reproduces the published grade AND the metric critic finds the same defect count 1 DISAGREE either the page and its api.json disagree, or real glyph widths change the defect count 2 usage 3 UNPROVEN no cdmap on the page, labels and marks do not pair, the frame is unreadable, api.json lacks the grade, or the font cannot be read -- a verdict this program could not reach is named, never acquitted The verdict line is LAST. Every number it decides on is printed above it so an outside reader can recompute the call. license_tier: ORIGINAL
