# Slot: noise_draw 


_How the base solve draws its noise realization, and therefore WHICH realization it is: `fused` draws the whole [n_steps, ...] tensor in one call, `blocked` regenerates each block of `block_size` steps from (key, block_index). Those are different draws from the same seed, so the grain is a declared property of the integration rather than something inferred from how the run is consumed. An observable declared `reduce: streaming` folds block by block whatever this says, because a reduction has no trajectory to fold otherwise; declare `blocked` to put the whole run on that same grain._
