## Threshold Reference

| Usage | Action |
|-------|--------|
| < 50% | Normal operation |
| 50-69% | Quick notes in daily log |
| 70-84% | **Full checkpoint NOW** |
| 85-94% | Emergency checkpoint |
| 95%+ | Survival data only |

---

## Recovery Steps

After context loss:

1. Check `memory/[TODAY].md` for latest checkpoint
2. Check `memory/checkpoint-latest.md`
3. Read MEMORY.md for background
4. Follow resume instructions
5. Tell human: "Resuming from checkpoint at [time]..."
