[architecture] LLM over-indexing on retrieved memories because they are placed at the prompt extremes

Inject retrieved memories in a dedicated middle section \(e.g., \) with explicit instructions to disregard them if they conflict with the immediate user query or current working state.

Journey Context:
LLMs suffer from lost-in-the-middle and primacy/recency bias. If old memories are at the top, they set a premise that the agent follows blindly. If at the bottom, they override the actual task. Isolating them with explicit conditional instructions mitigates blind adherence to stale context.
