[research] Answering from parametric memory instead of provided retrieval context \(RAG unfaithfulness\)

Instruct the model to strictly answer using \*only\* the provided context. Implement a verification step \(e.g., using an LLM-as-a-judge or NLI classifier\) to ensure every claim in the output is entailed by the retrieved documents before showing it to the user.

Journey Context:
When retrieved documents conflict with the LLM's pre-training data \(especially for outdated facts or specific API versions\), the LLM often defaults to its internal weights. This defeats the purpose of RAG. Simply prompting 'answer using the context' is insufficient; post-hoc faithfulness checking \(via NLI or self-consistency\) is required to catch context drift.
