01Summary
It filters out repeated, expired, or processed messages, retains only the latest 12 per turn, and uses watermarking to preserve session state. The system avoids replaying past interactions to prevent quadratic growth in token usage, ensuring efficient operation under high message volume.
Summarised from the original article by an open-source model, then checked automatically: every number and English name must appear in the source. The original article is authoritative.
02Key points

- Only the latest 12 messages per turn are passed, filtered for redundancy.
- Watermarking ensures state consistency and removes history on failed runs.
