    "body_text": "The proposed epistemic-warrant ladder classifies pairwise recommendations as unstable, context-dependent, locally supported or broadly supported. Known-groups tests recovered expert-prespecified orderings, and stronger certificates aligned with independent crowd consensus. Verbalized confidence did not explain the same information, nor could decision difficulty readily account for it. The contribution is a decision-level reliance framework validated in the authors' experiments, not a guarantee that a warranted answer is objectively true.",
