Write state to files before the window fills

Have the agent persist plans and intermediate results outside the context window, and re-read them as needed.

WHY IT HOLDS

Long-horizon tasks exceed any window. Persisting the plan means a truncation or reset doesn't lose the thread — Anthropic's research agent saves its plan to memory precisely because the context would otherwise be truncated.

WHAT IT PREVENTS

Losing the plan when context is truncated mid-task.
