[research] LLM ignores explicitly provided context in a prompt and relies on its pre-trained parametric memory instead

Structure the prompt to force context integration: require the model to extract direct quotes from the provided text before synthesizing the answer, and penalize responses that lack explicit grounding markers.

Journey Context:
When the provided context contradicts the model's pre-training data, the model often defaults to its internal weights because those pathways have been reinforced over billions of tokens. Simply saying 'use the provided context' is a weak signal against strong parametric priors. Forcing the model to perform an intermediate extraction step \(quote -> answer\) shifts the attention mechanism to prioritize the context window over internal weights.
