[architecture] Agent ignoring retrieved memories placed in the middle of the prompt

Structure the prompt so that highly critical retrieved memories or instructions are placed at the very beginning or the very end of the context window. Avoid placing crucial state in the middle of large retrieved text blocks.

Journey Context:
Research shows LLMs exhibit a U-shaped attention curve; they pay close attention to the beginning and end of the context window but ignore information in the middle. When agents inject 10 retrieved memories into the prompt, if the most important one is number 5, it will likely be ignored. The tradeoff is logical ordering vs. attention weighting. The fix is to re-rank retrieved memories not just by relevance, but by importance, and place the most important ones at the edges of the context block.
