about
nx_img_decode_gate.nx -- referee for JPEG wired into the shared decode path (nx_img_to_gray /
nx_img_to_rgb now route FF-D8-FF to the sovereign baseline JPEG decoder). The real web is JPEG, so
this is what unblocks perceptual-fingerprinting real media for the reverse-image discovery engine.
row1 JPEG -> gray dims -- the 137-byte all-128 baseline JPEG decodes to 8x8 via nx_img_to_gray.
row2 JPEG gray value -- decoded luma is ~128 (real IDCT, not a stub).
row3 JPEG -> rgb -- nx_img_to_rgb yields packed RGB ~ (128,128,128).
row4 CROSS-FORMAT MATCH -- dHash(JPEG) == dHash(PNG) for the same image (Hamming 0): a site serving
JPEG and a site serving PNG of the SAME media now MATCH -- the heart of cross-site reverse-image.
row5 PNG REGRESSION -- a red/green PNG still decodes correctly through nx_img_to_rgb (PNG path
intact after adding the JPEG branch).
GREEN iff 5/5. Durable verdict -> knowledge/status/img_decode_gate.log. license_tier: ORIGINAL
