# BlockRefinementScheduler

The `BlockRefinementScheduler` manages block-wise iterative refinement for discrete token diffusion. At each step it
commits the most confident tokens and optionally edits already-committed tokens when the model predicts a different
token with high confidence.

This scheduler is used by [`LLaDA2Pipeline`].
