Report #29827

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

Never trust model-generated citations without programmatic verification. Force the agent to output only URLs/DOIs retrieved from a search tool, and validate the link resolves to a 200 OK before presenting to the user.

Journey Context:
LLMs predict the next token, so they generate highly plausible-sounding paper titles and real author names combined into fake papers. This is a notorious failure mode in academic assistance. Post-hoc verification of the text string is insufficient; the citation must be grounded in an actual retrieved artifact.
