We describe Spindrift, A streaming post-processing layer that collapses short-horizon token repetitions introduced by nondeterministic decoding paths.. Inference stacks that batch requests or run across multi-GPU splits are not bit-exact across replicas.

Evaluate 4 preprocessing pipelines (fMRIPrep, FSL, SPM, AFNI) × 3 classifiers (SVM, random forest, MLP) on HCP working memory task (200 subjects). Main effect of pipeline: F(3,2388)=47.
