ref-verify

Prevents citation hallucination in academic writing. Invoke when: finding papers to support a specific claim; verifying/checking/auditing existing citations or DOIs; confirming whether a paper actually says what the user claims it says ('is that what the paper says?', 'did they actually show X?'); adding a citation by describing a paper ('add a citation for the paper where X'); running a pre-submission reference sweep. Do NOT invoke for: formatting references in APA/IEEE style, general topic explanations, citation style questions, or prose editing. Selects Quick Screen (seconds per paper) or Full Audit (abstract fetch + claim check) automatically.
