nx_parity_judge.nx -- THE ORGAN EYE (operator 2026-07-16: "this workflow isnt complete until you see the exact same issues i see without your or my involvement"). Given (oracle.png, nishi.png) of the SAME page, it autonomously reports the failure classes a human eyeball found on the top-20 suite -- so the suite self-diagnoses every run with NO human/Claude in the loop: BLANK-NISHI nishi has almost no ink while the oracle has plenty (google: blank page scored 97.3% parity by matching white space -- THE metric hole this organ closes) STRIP-COLLAPSE nishi's ink is squeezed into a narrow vertical band (bing/netflix: 1-char-per-line column collapse from a near-zero-width container) CANVAS-OFF the two sides disagree about the page background color (hackernews: dark canvas vs beige) SPARSE-NISHI nishi paints real ink but a fraction of the oracle's (missing bg-images/sections) CONTENT-OK ink mass + spread comparable -- grade quality by the parity numbers Ink = pixels differing from that side's own dominant background (corner-sampled) by > tol. usage: nx_parity_judge <oracle.png> <nishi.png> [nishi_y_offset] (offset skips the browser chrome bar) license_tier: ORIGINAL
