[architecture] Retrieving too many memories and overloading the context window

Cap retrieved memory tokens to a fixed budget \(e.g., 20% of context\) and use a cross-encoder reranker to filter before injection.

Journey Context:
Agents often retrieve top-K chunks blindly. Top-K does not respect the context window limit. If K is large, you hit context limits or degrade the LLM's instruction-following via the 'lost in the middle' phenomenon. Reranking ensures only the highest-signal memories consume the precious context budget, trading a small latency increase for significantly better reasoning.
