The K_eff = K/cond_scale compensation was making the correction too weak at high CFG (0.017 at cfg=12 vs paper's 0.2). The original paper uses full K and relies on cfg_scale * K amplification for stabilization. tanh smoothing + 5x5 spatial blur handle artifact prevention that the paper doesn't need in DiffSynth.
