about
nx_inr_pe_gate.nx -- R4b QUALITY rung: kill the coordinate-MLP spectral bias with POSITIONAL ENCODING so
the INR FAITHFULLY represents a real image patch (PSNR jumps from the plain-MLP ~20.8dB baseline). Uses
TRIANGLE-WAVE positional encoding (integer-only, unpatentable high-freq basis -- no sin/no fx import): each
coordinate is expanded into triangle waves at frequencies 1/2/4, giving the ReLU MLP pre-made high-frequency
piecewise-linear features it cannot synthesize from raw coords. Features are FIXED functions of the (fixed)
pixel coords -> the autograd is unchanged (just a wider input layer). All tools provably clean (triangle
wave = abs+mod, MLP/ReLU/SGD/autodiff = UNPAT) -> passes nx_codec_provenance_gate. license_tier: ORIGINAL
