[research] Blindly trusting retrieved documents as ground truth, causing the model to adopt the errors of the retrieval corpus

Implement a secondary verification step or prompt instruction that allows the model to reject retrieved context if it contradicts high-confidence parametric knowledge. Use metadata filtering to exclude low-quality sources.

Journey Context:
The standard RAG paradigm assumes 'retrieved = true'. But if the vector DB contains outdated StackOverflow answers or incorrect documentation, the model will faithfully hallucinate based on that poisoned context. The tradeoff is allowing the model to override context \(which risks ignoring new info it doesn't know\) vs. forcing it to use context \(which risks adopting garbage\). The right call is to instruct the model to weigh source reliability and cross-reference.
