[architecture] Aggressive summarization losing critical details vs. no summarization blowing up the context

Use a rolling buffer with a structured summarization trigger. Keep the last N messages verbatim, and summarize older messages into a structured format \(e.g., bulleted facts\) rather than a narrative paragraph, preserving entities and action items.

Journey Context:
To manage context windows, agents summarize past conversations. If you summarize too early or too aggressively, you lose specific details \(like order IDs or dates\). If you do not summarize, you exceed the token limit or degrade LLM performance. The common mistake is summarizing into a narrative paragraph, which dilutes facts. The fix is structured summarization \(extracting specific entities/relations\) combined with a sliding window of recent, unmodified context. This balances token efficiency with fact retention.
