[research] RAG system retrieving and trusting a single unverified source that contains misinformation

Implement multi-source retrieval and cross-validation. Require at least two independent, high-authority sources before asserting a factual claim as true. If sources conflict, present the ambiguity rather than picking one.

Journey Context:
RAG pipelines often retrieve the top-k results, but if the top result is a highly SEO-optimized but factually incorrect page, the LLM will faithfully summarize it. Grounding is not just about citing a source; it is about citing a reliable source. The tradeoff is increased retrieval cost and potential inability to answer niche questions, but it prevents the agent from becoming an amplifier for single-source misinformation.
