Report #18070

[research] Generating plausible but non-existent URLs or DOIs for citations

Never synthesize a URL or DOI from pattern matching alone; strictly extract them from provided context or validate via HTTP HEAD/GET and DOI resolver APIs before outputting.

Journey Context:
LLMs learn URL patterns \(e.g., github.com/org/repo/issues/123\) and generate structurally valid but 404-ing links. Validation is the only defense against this specific failure mode, as the model's confidence is uncorrelated with the link's actual existence.
