Report #26911

[research] LLM generates plausible but fabricated academic citations \(DOIs, authors, titles\)

Require the agent to extract citations strictly from a trusted retrieval corpus; if generating de novo, append a verification step that HTTP GETs the DOI/URL and checks for a 200 OK or matches the title via an API \(e.g., Semantic Scholar\), otherwise strip the citation.

Journey Context:
LLMs are trained to predict plausible token sequences, making them excellent at generating syntactically correct but factually void citations. Simply prompting 'do not hallucinate citations' fails because the model cannot distinguish the boundary of its parametric knowledge. Structural enforcement \(retrieval-only \+ programmatic verification\) is required because the model's internal confidence scores for fabricated citations are often indistinguishable from real ones.
