Leave-One-Out Corrective Parallel Sampler

Replace standard tau-leaping in discrete diffusion generation with a first-order sampler whose per-coordinate transition is conditioned on all other current coordinates and excludes the coordinate being updated. After a parallel proposal, use the same leave-one-out conditionals to correct coordinates whose newly sampled values are inconsistent with the rest of the state, allowing large timesteps without permanently propagating simultaneous denoising errors.

Modular collision-free sparse attention

Replace dense attention between grid-arranged tokens by a deterministic block-sparse pattern generated from modular permutations. In each block, connect row token i to column token p(i)=2i modulo B; because i, i-p(i), and i+p(i) are injective modulo B when gcd(B,6)=1, the pattern avoids repeated horizontal, vertical, and diagonal projections. Use shifted permutations across heads to increase receptive-field coverage while retaining structured sparsity.
