## 📁 Files to Create (MVP-Focused)

### Handlers (4 critical)
```
backend/src/handlers/
├── medications.rs        # MVP CRITICAL
├── health_stats.rs       # MVP CRITICAL
├── notifications.rs      # MVP CRITICAL
└── profiles.rs           # MVP CRITICAL (multi-person)
```

### Models (1 new)

└── notification.rs       # Notification model
```

### Tests
```

└── mvp_tests.rs         # MVP integration tests
```

### Scripts
```
backend/
├── test-mvp-workflow.sh  # End-to-end MVP test
└── mvp-demo-data.sh      # Seed demo data
```

---

## 🔒 MVP Security Requirements

### All Endpoints Must:
1. **Profile Isolation** - Users can only access their profiles
2. **Permission Checks** - Use existing permission middleware
3. **Audit Logging** - Log all health data access
4. **Input Validation** - Sanitize all health data

### Special Considerations:
- **Children's data** - Extra protection
- **Sharing** - Explicit consent only
- **Reminders** - No sensitive data in notifications

---

## 📝 Summary

**Phase 2.7 is now MVP-focused and prioritized.**

**Key Changes:**
- ✅ Medications moved to CRITICAL (was just "first")
- ✅ Health stats moved to CRITICAL (core value)
