about

nx_image_symmetry_lib.nx -- shared ImageBeauty core (NO main), so both the nx_image_beauty tool AND the nx_gen_rank tool score with ONE source of truth (OO/DRY, per the consolidate-via-atlas directive). go_image_symmetry = the objective_beauty.py _bilateral_symmetry integer port on the proven nx_png_decode. Object model: companion_arch.md. license_tier: ORIGINAL
