[counterintuitive] Packing the LLM context window with maximum retrieved documents

Limit retrieved chunks to top-k \(e.g., 3-5\) and place the most critical information at the very beginning or end of the prompt.

Journey Context:
Developers assume more context gives the model more evidence to reason with, improving accuracy. However, LLMs suffer from the 'Lost in the Middle' phenomenon: they attend strongly to the beginning and end of the context but ignore information in the middle. Over-stuffing context degrades accuracy, increases latency, and inflates cost without improving reasoning.
