Report #11729

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

Implement strict citation grounding: force the LLM to extract exact quotes from retrieved documents before generating the citation, and programmatically verify URLs/DOIs against an external database \(e.g., Semantic Scholar API\) rather than trusting the LLM's output string.

Journey Context:
LLMs are trained to be helpful and fluent, leading them to invent plausible-looking arXiv IDs or authors \(the fabricated citation failure mode\). Relying on the model to self-verify or asking 'are you sure?' usually results in confident doubling down. Programmatic verification is required because the model lacks a true world-model of valid document hashes.
