  blocked:
    text: blocked
    description: Regenerate each block's noise from the key and the block index. The
      realization never depends on the total step count, so a run measured by folding
      an observable in-carry and the same run materialized in full agree sample for
      sample. Holds no O(n_steps) noise tensor, and regenerates rather than stores
      on the backward pass. Keyed by Integrator.block_size.
  fused:
    text: fused
    description: Draw the whole [n_steps, n_noise_states, n_nodes] tensor once from
      the key. Fuses with the scan, but the realization is a function of the step
      count, so the same recipe measured two ways gives two trajectories, and the
      tensor costs as much memory as the trajectory it drives.
