Report #3602

[research] Hallucinated URLs and DOIs in generated academic or technical citations

Enforce strict retrieval-augmented generation \(RAG\) with exact string matching for URLs, or append a verification step that HTTP GETs the URL/DOI before outputting.

Journey Context:
LLMs are trained to predict plausible tokens, so 'https://arxiv.org/abs/2023.xxxxx' looks statistically likely. Post-hoc checking is required because the model's internal confidence score for these fabricated links is often erroneously high.
