### 7. ✅ Wellness Scoring System
- **API Endpoints**:
  - `/api/wellness/calculate.php` - Calculate comprehensive score
  - `/api/wellness/history.php` - Fetch score history & trends
- **Scoring Model** (100 points total):
  - Sleep Quality (0-20): 7-9hr ideal range
  - Physical Activity (0-20): Sessions + exercise frequency
  - Health Metrics (0-20): BP, HR, weight stability
  - Stress Management (0-20): Intake stress level conversion
  - Appointments (0-10): Session completion & scheduling
  - Wellness Engagement (0-10): Logs, purchases, documents
- **Database**: `wellness_scores` table stores all scores with history
- **Trends**: Shows category score changes vs previous calculation
- **Visualization**:
  - Stat card with overall score + color coding (green 70+, amber 40-70, red <40)
  - Breakdown section showing 6 categories with progress bars
  - Category icons and percentage indicators

### 8. ✅ Dashboard Integration
- **Dashboard File**: `dashboard/user/index.php` (838 lines)
- **Dynamic Sections**:
  - Wellness stat card with auto-loading
  - Wellness breakdown section with 6 categories
  - Notifications container with auto-refresh
  - Coach recommendations with personalized insights
  - Activity feed with filtering and pagination
  - Health data form submission
  - Medical report upload form
- **JavaScript Functions**:
  - `loadNotifications()` - Fetch notifications every 30s
  - `loadCoachRecommendations()` - Fetch coach notes every 60s
  - `loadActivityFeed()` - Load activity with pagination
  - `loadWellnessScore()` - Load wellness score + breakdown
  - `renderWellnessBreakdown()` - Render 6-category breakdown
  - `filterActivityType()` - Filter activity by type
- **Initialization**: DOMContentLoaded event loads all data on page entry

## Database Tables Created

### health_metrics
```
id, user_id, systolic_bp, diastolic_bp, heart_rate, 
sleep_hours, weight, notes, created_at
```

### medical_reports
```
id, user_id, filename, file_path, mime_type, 
file_size, uploaded_at
```

### notifications
```
id, user_id, type, title, message, color, icon, 
is_read, created_at
```

### coach_notes
```
id, user_id, coach_id, note, created_at, updated_at
```

### wellness_scores
```
id, user_id, overall_score, sleep_score, activity_score, 
health_score, stress_score, appointment_score, 
wellness_engagement_score, score_breakdown (JSON), 
calculated_at
```

## API Architecture

All endpoints follow consistent patterns:

**Authentication**: `hw_require_auth(['client'])` on all endpoints
**Response Format**: JSON with `success` flag and data/error fields
**Database**: Auto-creates tables on first use
**Security**: Prepared statements, input validation, user_id scoping

## Frontend Technologies

- **Vanilla JavaScript**: No frameworks required
- **Fetch API**: For async data loading
- **CSS Grid/Flexbox**: Responsive layouts
- **FontAwesome Icons**: Visual indicators
- **Real-time Updates**: Auto-refresh intervals for key sections

## File Structure

### Core Dashboard Files
- `dashboard/user/index.php` - Main dashboard (838 lines)
- `dashboard/user/activity.php` - Full activity history page

### API Endpoints (All in /api/)
- `users/share-health-data.php` - Health metrics submission
- `users/upload-medical-report.php` - Document upload
- `users/activity-feed.php` - Activity aggregation
- `notifications/dashboard.php` - Notification generation
- `recommendations/coach.php` - Coach insights
- `wellness/calculate.php` - Score calculation
- `wellness/history.php` - Score history & trends

### Documentation
- `HEALTH_DATA_IMPLEMENTATION.md` - Health API documentation
- `NOTIFICATIONS_IMPLEMENTATION.md` - Notifications system
- `ACTIVITY_FEED_IMPLEMENTATION.md` - Activity feed details
- `WELLNESS_SCORING_IMPLEMENTATION.md` - Wellness scoring model
- `IMPLEMENTATION_SUMMARY.md` - This file

## Testing & Validation

### Manual Testing
1. Create health metrics (blood pressure, heart rate, sleep, weight)
2. Submit intake form with stress level
3. Schedule and complete appointments
4. Upload medical documents
5. Make store purchases
6. Verify wellness score calculates
7. Check dashboard displays all components

### Expected Behavior
- Dashboard loads with spinner animations
- Wellness score displays within 1 second
- Notifications update every 30 seconds
- Recommendations refresh every 60 seconds
- Activity feed pagination works smoothly
- All data is user-scoped (no cross-user data leaks)

## Performance Considerations

1. **API Calls**: Minimal - ~5 concurrent requests on page load
2. **Auto-Refresh**: Intervals set conservatively (30s notifications, 60s recommendations)
3. **Database Queries**: Use indexes on (user_id, created_at) for efficient sorting
4. **JSON Storage**: Breakdown object stored as JSON for flexibility

## Security Features

1. **Authentication**: All endpoints require `hw_require_auth()` 
2. **User Scoping**: Every query filtered by authenticated user_id
3. **Input Validation**: Range checks on health metrics
4. **File Upload**: MIME type validation, file size limits
5. **SQL Injection**: Prepared statements on all queries
6. **CORS**: Credentials included in fetch requests

## Future Enhancement Opportunities

1. **Automated Scoring**: Cron job for daily wellness score calculation
2. **Wellness Goals**: User-defined targets for each category
3. **Trend Charts**: Line graphs showing score progression
4. **Export/Reports**: PDF generation of wellness data
5. **Goal Achievements**: Badges/milestones for wellness milestones
6. **Predictive Insights**: ML-based recommendations
7. **Social Features**: Share wellness achievements with coaches
8. **Mobile App**: Native app with offline support

## Maintenance Notes

### Regular Tasks
- Monitor database growth of wellness_scores (consider archiving old records)
- Review notification content for relevance
- Update wellness scoring weights based on user feedback

### Backup Considerations
- Include health_metrics, medical_reports, wellness_scores in regular backups
- Consider GDPR implications of medical data storage
- Implement data retention policies for sensitive documents
