Report #50652

[research] LLM generates plausible but non-existent academic citations or DOIs when asked for literature references

Require the agent to extract citations strictly from a verified retrieval corpus; never generate a DOI or URL from parametric memory. If no corpus exists, append a hardcoded disclaimer that citations are generated and must be verified.

Journey Context:
LLMs are trained to predict plausible token sequences, making them excellent at generating syntactically valid but factually void DOIs \(e.g., 10.1234/fake\). Checking syntax isn't enough; only external grounding breaks this failure mode.
