Four-stage fact check of a claim
Overview
This prompt tests one claim against a passage from a source in four fixed stages: pull out literal statements, rate the source's reliability, judge whether the claim is supported, then look for other readings. It ends with a verdict of supported, contradicted, or not enough info, plus a brief reason.
