# 🎯 Phase 2.7 - MVP Prioritized Summary

## 🚨 Priority Shift Based on MVP Research

Based on the Normogen MVP research, I've **reprioritized Phase 2.7** to focus on the most critical features that deliver core value to users.

---

## 📊 What Changed?

### Original Priority (Generic Health Features)
1. Medications
2. Lab Results  
3. Health Statistics
4. Appointments
5. Health Documents

### ✅ New Priority (MVP-Driven)
1. **💊 Medications** - CRITICAL (medication adherence is THE killer feature)
2. **📈 Health Statistics** - CRITICAL (trends & patterns)
3. **👨‍👩‍👧 Profiles** - CRITICAL (multi-person support for families)
4. **🔗 Basic Sharing** - IMPORTANT (family caregivers)
5. **🔔 Notifications** - CRITICAL (medication reminders)

### Demoted/Deferred
- ⚠️ **Lab Results** → Nice-to-have (useful but not MVP-critical)
- ⚠️ **Appointments** → Nice-to-have (basic scheduling, not core)
- ❌ **Health Documents** → Deferred (file upload is complex, low MVP value)

---

## 🎯 MVP Core Users (from research)

1. **Parents** tracking children's medications and health
2. **Individuals** managing their own medications
3. **Families** sharing health data with caregivers

---

## 🚀 Implementation Order

### 1. Start Here: Medications 💊
```bash
# Create handler
touch backend/src/handlers/medications.rs

# Add endpoints
- POST   /api/medications
- GET    /api/medications
- GET    /api/medications/:id
- PUT    /api/medications/:id
- DELETE /api/medications/:id
- POST   /api/medications/:id/log
- GET    /api/medications/:id/adherence
```

**Why start here?** It's the core MVP feature and demonstrates the most value.

### 2. Next: Health Statistics 📈
```bash
touch backend/src/handlers/health_stats.rs

# Add endpoints
- POST   /api/health-stats
- GET    /api/health-stats
- GET    /api/health-stats/trend/:type
- DELETE /api/health-stats/:id
```

### 3. Then: Profiles 👨‍👩‍👧
```bash
touch backend/src/handlers/profiles.rs

# Add endpoints
- GET    /api/profiles
- POST   /api/profiles
- PUT    /api/profiles/:id
- GET    /api/profiles/:id/health-stats
- GET    /api/profiles/:id/medications
```

### 4. Sharing: Enhance Existing 🔗
```bash
# Enhance backend/src/handlers/shares.rs
# Add health data sharing to existing Share model
```

### 5. Finally: Notifications 🔔
```bash
touch backend/src/handlers/notifications.rs
touch backend/src/models/notification.rs

# Add endpoints
- POST   /api/notifications
- GET    /api/notifications
- PUT    /api/notifications/:id/read
- DELETE /api/notifications/:id
```

---

## 🔒 Security Considerations

### All endpoints must:
1. ✅ Use existing authentication middleware
2. ✅ Check profile ownership (user can only access their profiles)
3. ✅ Log all health data access (audit logging)
4. ✅ Validate all input data
5. ✅ Sanitize error messages (no data leakage)

### Special considerations:
- **Children's data** - Extra protection, limited sharing
- **Sharing** - Explicit consent only, expiring links
- **Reminders** - No sensitive data in notifications

---

## 📊 Success Metrics

### Technical
- ✅ All MVP endpoints operational
- ✅ < 500ms p95 response time
- ✅ 80%+ test coverage
- ✅ Zero security vulnerabilities
- ✅ Deployed to Solaria

### User Value
- ✅ Can manage medications for entire family
- ✅ Can track health trends over time
- ✅ Can receive medication reminders
- ✅ Can share data with caregivers

---

## 📝 Key Differences from Original Plan

### What Got Prioritized UP
- **Notifications** - Added as CRITICAL (wasn't in original plan)
- **Profiles** - Prioritized as CRITICAL (was "later")
- **Sharing** - Prioritized as IMPORTANT (was "basic")

### What Got Prioritized DOWN
- **Lab Results** - Demoted to NICE-TO-HAVE (was #2)
- **Appointments** - Demoted to NICE-TO-HAVE (was #4)
- **Documents** - REMOVED entirely (deferred to Phase 4)

### Why These Changes?

**Medications are THE killer feature**
- Most users want to track medications
- Adherence tracking is unique value prop
- Huge market need (parents, elderly, chronic conditions)

**Health stats are more valuable than lab results**
- Users track daily (weight, BP)
- Lab results are occasional
- Trends matter more than individual tests

**Profiles enable the family use case**
- Multi-person support is core to vision
- Parents managing children's health
- Caregivers helping elderly parents

**Notifications drive engagement**
- Reminders keep users coming back
- Missed dose alerts create value
- Essential for medication adherence

**Sharing enables trust**
- Families need to share health data
- Caregivers need access
- Control is maintained (expiring links)
