EntropyBoundScheduler

The EntropyBoundScheduler commits the lowest-entropy positions whose joint entropy stays under entropy_bound, so roughly independent tokens are accepted together and the rest are renoised. It anneals its sampling temperature from t_max on the first step down to t_min on the last, matching the released checkpoint's sampler. Proposed in Accelerated Sampling from Masked Diffusion Models via Entropy Bounded Unmasking.

This scheduler is used by [DiffusionGemmaPipeline].
