- What changed
- Researchers proposed a hierarchical architecture with time-scaled levels, clocked ticks, and cascaded intelligence to support long-horizon language-model agents.
- Why you should care
- Long-horizon agent stability requires harness design features that outlive single context windows and session boundaries.
- Your move
- Watch. Monitor how hierarchical harness designs impact multi-day agent task reliability.
- What to watch next
- Independent replication of multi-day agent campaigns using the proposed hierarchical architecture.
