Use when checking whether the local library supports given textual claims — claims with explicit citekeys, claims attributing positions to named authors, or claims about what a source "argues" / "shows" / "finds" / "concludes". Enumerates each citation-bearing claim, invokes the grounding-against-library kernel per claim, and reports a claim table with verbatim quoted support and a status (match / partial / mismatch / not-found). Multi-source. Catches "doesn't contradict" passing as "supports", silent qualifier-stripping, and one-chunk-dispositive errors. Also fires on phrasings like "verify these claims against my library", "fact-check this passage", "are these citations warranted", "does my library actually back these claims", "is @<citekey> really saying X", "check whether the cited sources support this".
