Report #101230

[research] LLMs invent paper titles, authors, DOIs, and URLs that look authoritative

Before citing anything, retrieve the source with a tool and confirm the DOI/URL resolves. If you cannot verify, say the claim is unverified and do not invent a citation.

Journey Context:
Hallucinated references are a well-documented failure mode in NLG surveys. Ji et al. \(2023\) taxonomize factual hallucination, and arXiv has started banning authors over unchecked AI-generated references. The safer pattern is source-first: only attach a citation after retrieval confirms the metadata; never backfill a citation to make an answer look credible.
