[research] LLM generating fabricated academic citations or URLs that 404

Mandate strict citation verification: extract claimed URLs or DOIs and perform a HEAD request or web search before outputting. If unverifiable, strip the citation and append an uncertainty disclaimer.

Journey Context:
LLMs are trained to predict plausible token sequences, making them excellent at generating realistic-looking but fake URLs and paper titles \(the plausibility trap\). Agents often trust these because they look structurally valid. The tradeoff is latency: verifying citations takes an extra tool-call round, but it is strictly necessary because a fabricated citation is worse than no citation—it actively misleads the user and destroys trust.
