[research] Ignoring provided factual context in favor of popular but incorrect parametric memory

Prepend context with a strong system instruction: 'Answer using ONLY the provided text. If the text contradicts common knowledge, follow the text.' Additionally, lower the temperature to reduce the probability mass given to high-frequency parametric tokens.

Journey Context:
Models are heavily regularized by their pre-training data. If a RAG context contains a niche or fictional fact, the model's attention mechanism is often overwhelmed by the pre-training weight of the popular counter-fact. Lowering temperature and strict negative constraints \('Do NOT use prior knowledge'\) are required to force context adherence over parametric prior.
