about

nx_image_fidelity_test.nx -- prove the "rebuild exactly" measurement gate on three rebuilds of a reference image: a PERFECT copy (must read LOSSLESS), a QUANTIZED rebuild (low bits dropped, must read NEAR-LOSSLESS, high PSNR), and a BAD rebuild (heavy error, must read LOSSY, low PSNR). The metric must rank them correctly -- the precision-measurement loop the generation stack needs. license_tier: ORIGINAL
