[research] LLM changes a correct answer to an incorrect one after being given retrieved context containing irrelevant distractors

Implement a 'relevance check' step where the LLM evaluates whether the retrieved context actually contains the answer \*before\* generating the final response, allowing it to fall back to parametric memory or 'I don't know' if the context is irrelevant.

Journey Context:
Standard RAG assumes retrieved context is helpful. However, retrieval systems often return documents that look topically relevant but lack the specific answer \(distractors\). LLMs are highly susceptible to context contamination: they will override their own correct parametric knowledge to parrot a misleading or incomplete retrieved document. Explicitly prompting the model to judge context relevance breaks the blind obedience to the RAG context.
