Design guidance

SHOULD combine verifiers with diverse training data, architectures or strategies; homogeneous ensembles add little.
SHOULD escalate to more sophisticated verification or human review when verifiers disagree.
MAY require unanimous agreement for approval but majority for rejection in high-stakes domains.
