about

nx_critvis_lib.nx -- IMPORTABLE photoreal-critic scoring axes, extracted verbatim from the gate _hdl_build/nx_critic_visual.nx (which holds a main() and so cannot be imported). Same axes, same scaling, same names -> a future dedupe can swap the gate's local copies for this import with zero behavior change. Axes: fine_detail (1px micro-contrast over foreground) + STRUCTURE (8x8 block-mean variance; rejects noise) + chroma MAD; score = MIN of scaled axes, /1000; verdict PHOTOREAL>=700 / STYLIZED-CG>=400 / CLAY. license_tier: ORIGINAL
