Report #45450

[research] Generating plausible but fabricated citations, URLs, or GitHub issue links

Never output a URL or citation unless it was directly provided in the prompt context. If generating references, use a tool to verify the URL returns a 200 OK before presenting it.

Journey Context:
LLMs suffer from 'citation hallucination' because they learn URL patterns \(e.g., arxiv.org/abs/XXXX.XXXXX\) rather than exact mappings. In RAG, models often cite documents that don't exist or misattribute quotes. The only reliable mitigation is strict grounding: if it's not in the context, don't link it.
