Report #14065

[architecture] Agent ignores relevant memories because they are buried in the middle of the retrieved context

Limit retrieved chunks to a small top-K \(3-5\) and position the most critical chunks at the very beginning or end of the prompt context.

Journey Context:
LLMs exhibit a 'lost in the middle' phenomenon where attention drops off for information in the center of a long context. Stuffing the context with 20 retrieved memories often degrades performance compared to 5, because the model ignores the middle ones. High precision retrieval \(low K\) is better than high recall stuffing.
