Report #16413

[research] LLM generates plausible but non-existent academic citations \(DOIs, arXiv IDs, author lists\)

Never trust model-generated citations without programmatic verification. Extract the claimed identifier and execute a search against the official API \(e.g., Semantic Scholar, Crossref, arXiv\) before presenting to the user.

Journey Context:
LLMs are trained to predict plausible token sequences, not to query databases. A valid-looking DOI checksum is just a statistical pattern to an LLM. Relying on the model to 'know' if a paper exists leads to high false-positive rates. Verification must be external and automated.
