about

nx_imgquery_e2e_gate.nx -- END-TO-END referee for hybrid reverse-image query on REAL decoded PNGs. Builds a real RGB PNG corpus, decodes every image through nx_img_to_rgb (and luma for dHash), computes each item's dHash + 112-dim imgsig, then runs the hybrid query (nx_imgquery copy + similar tiers). corpus: A=red V-stripes, B=green V-stripes (same structure as A, different color), C=red checker, D=green checker. queries built as separate PNGs and decoded the same way. row1 COPY exact -- Q1 (a re-encoded copy of A) is found in the COPY tier at Hamming 0. row2 dHash COLORBLIND-- dHash(A) ~ dHash(B): a red and a green image of the SAME structure are indistinguishable to dHash (Hamming <= copy_thresh) -- the gap color fills. row3 COLOR disambiguates -- imgsig nearest to Q1 is A, and imgsig(Q1,A) < imgsig(Q1,B): the hybrid tells the TRUE copy from its different-color structural twin. row4 LOOK-ALIKE -- Q2 (a red V-stripes image of a DIFFERENT period) is NOT a dHash copy of A (Hamming > copy_thresh) yet imgsig nearest = A: a match the copy tier misses. row5 HYBRID ORDERING -- imgsig(Q2,A) < imgsig(Q2,B) and < imgsig(Q2,C): structure AND color jointly correct, on REAL decoded pixels. GREEN iff 5/5. Durable verdict -> knowledge/status/imgquery_e2e_gate.log. license_tier: ORIGINAL
