## 🎯 Quick Verdict

✅ **APPROVE WITH MODIFICATIONS**

**Key Finding:** Running GCT achieves ±30-50ms (recreational scope, not elite)

**Critical Actions:**

1. Validate foot_index visibility (2 hours in Task 1)
1. Plan validation study for Month 3-4
1. Accept recreational running scope in marketing
