[architecture] Agent repeating or getting stuck on the most recent context regardless of relevance

When retrieving memories, apply a recency penalty or normalize timestamps so that older but highly relevant memories aren't overshadowed by recent but irrelevant ones. Re-order retrieved context so the most relevant items are at the very beginning and end of the injected text.

Journey Context:
LLMs suffer from recency bias \(lost-in-the-middle phenomenon\). If you just append retrieved memories chronologically, the agent over-focuses on the last thing injected. People try to fix this by just getting more memories, which makes it worse. The fix is re-ordering retrieved context and applying time-decay weighting during the retrieval scoring phase, ensuring the middle of the context window isn't where critical data lives.
