[research] Generating plausible but fake URLs, DOIs, or paper titles when asked for references or documentation links

Never generate raw URLs or DOIs from memory; only output links explicitly retrieved from a search tool, and append a disclaimer if a link cannot be verified via browsing.

Journey Context:
LLMs are generative models trained on text patterns, not databases. They will construct URLs that perfectly match the format of a GitHub repo or ArXiv paper but lead to 404s or entirely different content. This is a critical failure mode for research or citation agents. Tool-use for URL retrieval is mandatory to maintain factual grounding.
