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

Force retrieval augmentation for any citation, and strictly validate DOIs/URLs via an external tool before outputting them; never trust parametric memory for citations.

Journey Context:
LLMs are trained to be helpful and will synthesize a plausible-sounding paper by combining real authors, real journals, and plausible titles. This is a known failure mode of parametric memory. Simply prompting 'do not hallucinate citations' fails because the model doesn't know the boundary between its training data and generation. The only reliable fix is architectural: citations must come from a verified retrieval step, not generation.
