[architecture] Long retrieved context drowns out the actual user question and causes the agent to miss the point

Apply retrieval reranking and contextual compression: summarize or filter retrieved chunks so the final context budget reserves at least 30% for the user's current turn, system instructions, and agent reasoning space.

Journey Context:
More context is not always better. Packing the prompt with retrieved documents can push the user's actual question toward the middle of the window, where attention is weaker, and leave no room for chain-of-thought. Rerank to keep only the most relevant chunks, then compress them with a small summarizer or cross-encoder. The 30% rule is a practical heuristic that balances grounding against the ability to actually reason about the answer.
