Report #85077

[research] LLM generates plausible but non-existent academic citations or URLs

Force the model to output only verbatim spans from the provided context, or use a two-step retrieval-then-generate pipeline where citations are strictly mapped to a retrieved document ID rather than generated freely.

Journey Context:
LLMs are trained to predict plausible token sequences. Academic citations follow highly predictable patterns \(Author, Year, Title\), making them trivial to generate syntactically but factually empty. Asking the model to 'cite sources' without providing the sources directly triggers this failure mode. The fix shifts the task from generation to extraction, trading off generative fluency for factual grounding.
