[architecture] Placing critical retrieved memories in the middle of a long context window resulting in the LLM ignoring them

Position critical retrieved context and instructions at the very beginning or very end of the prompt payload. Use the middle for background or filler context.

Journey Context:
LLMs exhibit U-shaped attention curves. Information in the middle of long contexts is often ignored or forgotten. When assembling the prompt, dynamically order the retrieved chunks so the highest-scoring chunks are placed at the edges of the context window, ensuring the model actually attends to the most relevant data.
