[research] LLM generates plausible but fabricated academic citations and DOIs

Implement strict citation grounding by forcing the LLM to output verbatim spans from the source text; reject any citation not exactly matching the retrieved document metadata.

Journey Context:
LLMs are trained on vast corpora where DOIs and titles follow strict patterns, making hallucinated references look structurally perfect. Relying on the LLM to 'recall' a citation fails because it generalizes the pattern rather than retrieving the specific instance. Structural validation \(regex for DOI\) is insufficient; exact-match grounding against a trusted corpus is required to prevent the model from inventing plausible but non-existent references.
