[architecture] How to stop old retrieved context from polluting the agent's current reasoning?

Implement context isolation by summarizing older context into a separate 'core memory' block rather than appending raw history, and apply recency weighting/decay to retrieval scores.

Journey Context:
LLMs suffer from the 'Lost in the Middle' effect and recency bias. If you just append retrieved memories or long conversation logs, the agent gets confused and hallucinates based on stale, irrelevant details. Summarization compresses the signal, while decay functions ensure older, less relevant facts don't override current directives. Raw history is a liability; compressed state is an asset.
