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

We present a step-by-step workflow for answering treatment hierarchy questions in both frequentist and Bayesian CNMA, including explicitly identifying the uniquely estimable relative effects.

C2weakest assumption

That identifying uniquely estimable relative effects is always feasible from the network structure and sufficient to construct valid non-misleading hierarchies without further assumptions on connectivity or data.

C3one line summary

A workflow for treatment hierarchies in CNMA that identifies uniquely estimable relative effects in frequentist and Bayesian settings.
