[research] Extracting incorrect facts because the retrieved context contains irrelevant distractors or conflicting passages

Implement a relevance filtering step \(e.g., cross-encoder reranking\) before passing documents to the LLM. Instruct the LLM to explicitly state which document supports the answer, and discard answers that rely on documents below a similarity threshold.

Journey Context:
Naive RAG pipelines often pass the top-K results from a vector search directly to the LLM. Vector search returns nearest neighbors, which can be topically similar but factually irrelevant distractors. LLMs are highly susceptible to distractor context—they will try to synthesize an answer from the provided text even if the text doesn't actually answer the question, leading to confabulation. Reranking tightens the signal-to-noise ratio, and forcing citation allows programmatic verification that the answer is grounded in a high-relevance chunk.
