about

_imgscramble.nx -- RED-TEAM INSTRUMENT for the image graders (operator 2026-08-04: "is this eval doing the work or is it junk"): shuffle an image's PxP patches with a seeded deterministic permutation. Scrambling DESTROYS all aesthetic/structural content (the face, the figure, the composition) while approximately preserving LOCAL statistics -- so any judge that scores an image ~equal to its scramble is measuring texture, not beauty, and cannot rank a styled character above a blob. license_tier: ORIGINAL _imgscramble <in.png> <out.png> <patch_px>
