nx_game_critic.nx

nx_game_critic.nx -- the REAL experiential QUALITY critic (not a floor check). nx_frame_sanity only proves a frame isn't BROKEN (not blown/void, has some edges); it green-lit toy games (flat discs on an empty starfield) as if they were good. That is the self-flattery the output-reality doctrine forbids. This critic measures whether a rendered game frame reads as RICH vs TOY, on dimensions that actually separate them, and returns an honest verdict TOY/BASIC/RICH/SOTA. You CLIMB against this, never the eyeball's flattery. Calibrated so a flat-primitive frame scores TOY and a detailed/shaded/textured frame scores higher -- the gate mutation-proves it distinguishes them. Dimensions (all integer, on a packed-pixel i64 fb = swgpu/game_raster format): [0] palette -- distinct quantized colours (5-bit/chan). Flat fills ~ a dozen; rich art >> 40. [1] detail1 -- fine 1px luma-step density permil (texture/edges up close). [2] detail4 -- 4px luma-step density permil (structure at a coarse scale -- real composition). [3] gradient -- pixels inside a SMOOTH shade ramp permil (lighting/depth, not flat colour blocks). [4] coverage -- non-background pixels permil (a filled scene vs mostly-empty void).
