The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

By using the previous belief as an informative source distribution, it enables substantially faster sampling than naive resampling from scratch while achieving performance competitive with full-step diffusion on distributional metrics.

C2weakest assumption

That a learned flow can reliably transport the full posterior distribution (including multimodality) from one time step to the next without accumulating approximation error or requiring retraining when the observation model changes.

C3one line summary

Sequential Bayesian Flow Matching accelerates flow-based sampling for streaming probabilistic inference by transporting posteriors recursively like Bayesian filters rather than restarting from noise each step.
