## 📋 Pre-Deployment Checklist

### 1. Environment Setup

- [ ] **Backend Environment Variables**
  - Ensure Redis is configured and accessible
  - Verify database migrations are up to date
  - Check that tenant service has access to usage data

- [ ] **Frontend Environment Variables**
  - Verify API client base URL is correct
  - Check that translation files are loaded properly
  - Ensure React Query is configured

### 2. Database & Redis

- [ ] **Run Database Migrations** (if any)
  ```bash
  # From services/tenant directory
  alembic upgrade head
  ```

- [ ] **Verify Redis Connection**
  ```bash
  # Test Redis connection
  redis-cli ping
  # Should return: PONG
  ```

- [ ] **Test Usage Data Storage**
  - Verify that usage metrics are being tracked
  - Check that Redis keys are being created with proper TTL (60 days)

### 3. Backend Deployment

- [ ] **Register New API Endpoints**

  **In `services/tenant/app/main.py`**, add usage forecast router:
  ```python
  from app.api.usage_forecast import router as usage_forecast_router

  # Register router
  app.include_router(
      usage_forecast_router,
      tags=["usage-forecast"]
  )
  ```

- [ ] **Deploy Backend Services**
  ```bash
  # Restart tenant service
  docker-compose restart tenant-service
  # or with kubernetes
  kubectl rollout restart deployment/tenant-service
  ```

- [ ] **Verify Endpoints**
  ```bash
  # Test usage forecast endpoint
  curl -X GET "http://your-api/usage-forecast?tenant_id=YOUR_TENANT_ID" \
    -H "Authorization: Bearer YOUR_TOKEN"

  # Should return forecast data with metrics array
  ```

### 4. Frontend Deployment

- [ ] **Install Dependencies** (if needed)
  ```bash
  cd frontend
  npm install
  ```

- [ ] **Build Frontend**
  ```bash
  npm run build
  ```

- [ ] **Run Tests** (if you have them)
  ```bash
  npm run test
  ```

- [ ] **Deploy Frontend**
  ```bash
  # Deploy to your hosting platform
  # Example for Vercel:
  vercel --prod

  # Example for Docker:
  docker build -t bakery-ia-frontend .
  docker push your-registry/bakery-ia-frontend:latest
  kubectl rollout restart deployment/frontend
  ```

### 5. Translation Verification

- [ ] **Test All Languages**
  - [ ] English (en): Navigate to subscription page, switch language
  - [ ] Spanish (es): Verify all feature names are translated
  - [ ] Basque (eu): Check special characters display correctly

- [ ] **Verify Missing Keys**
  ```bash
  # Check for missing translation keys in browser console
  # Look for warnings like: "Missing translation key: features.xyz"
  ```

### 6. Analytics Integration

- [ ] **Choose Analytics Provider**
  - [ ] Segment (recommended for multi-provider)
  - [ ] Mixpanel (recommended for funnel analysis)
  - [ ] Google Analytics 4 (recommended for general tracking)

- [ ] **Update Analytics Configuration**

  **In `frontend/src/utils/subscriptionAnalytics.ts`**, replace the `track` function:

  ```typescript
  // Example for Segment
  const track = (event: string, properties: Record<string, any> = {}) => {
    if (typeof window !== 'undefined' && window.analytics) {
      window.analytics.track(event, {
        ...properties,
        timestamp: new Date().toISOString(),
        page_path: window.location.pathname
      });
    }

    // Keep local storage for debugging
    const events = JSON.parse(localStorage.getItem('subscription_events') || '[]');
    events.push({ event, properties, timestamp: new Date().toISOString() });
    localStorage.setItem('subscription_events', JSON.stringify(events.slice(-100)));
  };

  // Example for Mixpanel
  const track = (event: string, properties: Record<string, any> = {}) => {
    if (typeof window !== 'undefined' && window.mixpanel) {
      window.mixpanel.track(event, {
        ...properties,
        timestamp: new Date().toISOString(),
        page_path: window.location.pathname
      });
    }

    // Keep local storage for debugging
    const events = JSON.parse(localStorage.getItem('subscription_events') || '[]');
    events.push({ event, properties, timestamp: new Date().toISOString() });
    localStorage.setItem('subscription_events', JSON.stringify(events.slice(-100)));
  };

  // Example for Google Analytics 4
  const track = (event: string, properties: Record<string, any> = {}) => {
    if (typeof window !== 'undefined' && window.gtag) {
      window.gtag('event', event, {
        ...properties,
        timestamp: new Date().toISOString(),
        page_path: window.location.pathname
      });
    }

    // Keep local storage for debugging
    const events = JSON.parse(localStorage.getItem('subscription_events') || '[]');
    events.push({ event, properties, timestamp: new Date().toISOString() });
    localStorage.setItem('subscription_events', JSON.stringify(events.slice(-100)));
  };
  ```

- [ ] **Test Event Tracking**
  - [ ] Open browser console → Application → Local Storage
  - [ ] Look for `subscription_events` key
  - [ ] Verify events are being captured
  - [ ] Check your analytics dashboard for real-time events

### 7. Cron Jobs (Optional but Recommended)

Set up daily cron job to track usage snapshots for trend analysis.

- [ ] **Create Cron Script**

  **File: `scripts/track_daily_usage.py`**
  ```python
  #!/usr/bin/env python3
  """
  Daily usage tracker cron job
  Tracks usage snapshots for all tenants to enable trend forecasting
  """
  import asyncio
  from datetime import datetime
  from services.tenant.app.core.database import get_db
  from services.tenant.app.models import Tenant
  from services.tenant.app.api.usage_forecast import track_daily_usage

  async def track_all_tenants():
      """Track usage for all active tenants"""
      async for db in get_db():
          tenants = db.query(Tenant).filter(Tenant.is_active == True).all()

          for tenant in tenants:
              # Get current usage counts
              usage = await get_tenant_usage(db, tenant.id)

              # Track each metric
              for metric, value in usage.items():
                  await track_daily_usage(
                      tenant_id=tenant.id,
                      metric=metric,
                      value=value
                  )

          print(f"[{datetime.now()}] Tracked usage for {len(tenants)} tenants")

  if __name__ == '__main__':
      asyncio.run(track_all_tenants())
  ```

- [ ] **Schedule Cron Job**
  ```bash
  # Add to crontab (runs daily at 2 AM)
  crontab -e

  # Add this line:
  0 2 * * * /usr/bin/python3 /path/to/scripts/track_daily_usage.py >> /var/log/usage_tracking.log 2>&1
  ```

- [ ] **Or Use Kubernetes CronJob**
  ```yaml
  apiVersion: batch/v1
  kind: CronJob
  metadata:
    name: usage-tracker
  spec:
    schedule: "0 2 * * *"  # Daily at 2 AM
    jobTemplate:
      spec:
        template:
          spec:
            containers:
            - name: usage-tracker
              image: your-registry/tenant-service:latest
              command: ["python3", "/app/scripts/track_daily_usage.py"]
            restartPolicy: OnFailure
  ```

   docker-compose up -d

   # Or with Kubernetes
   kubectl apply -f k8s/tenant-service.yaml
   kubectl rollout status deployment/tenant-service
   ```

3. **Verify Backend Health**
   ```bash
   # Test usage forecast endpoint
   curl -X GET "http://your-api/usage-forecast?tenant_id=test" \
     -H "Authorization: Bearer $TOKEN"

   # Should return 200 OK with forecast data
   ```

### Step 2: Frontend Deployment (30 minutes)

1. **Existing Page Already Enhanced**

   ```html
   <!-- Segment (recommended) -->
   <script>
     !function(){var analytics=window.analytics=window.analytics||[];...}();
     analytics.load("YOUR_SEGMENT_WRITE_KEY");
   </script>

   <!-- OR Mixpanel -->
   <script>
     (function(f,b){if(!b.__SV){...}})(document,window.mixpanel||[]);
     mixpanel.init("YOUR_MIXPANEL_TOKEN");
   </script>

   <!-- OR Google Analytics 4 -->
   <script async src="https://www.googletagmanager.com/gtag/js?id=G-XXXXXXXXXX"></script>
   <script>
     window.dataLayer = window.dataLayer || [];
     function gtag(){dataLayer.push(arguments);}
     gtag('js', new Date());
     gtag('config', 'G-XXXXXXXXXX');
   </script>
   ```

2. **Update Analytics Config** (see checklist above)

## 📊 Post-Deployment Monitoring

### Week 1: Monitor Key Metrics

Track these metrics in your analytics dashboard:

1. **Engagement Metrics**
   - Subscription page views
   - Time on page
   - Bounce rate
   - Feature list expansions
   - Plan comparison views

2. **Conversion Metrics**
   - Upgrade CTA clicks (by source)
   - ROI calculator usage
   - Plan comparison usage
   - Upgrade completions
   - Conversion rate by tier

3. **Usage Metrics**
   - High usage warnings shown
   - Users at >80% capacity
   - Predicted breach dates accuracy
   - Daily growth rate trends

4. **Technical Metrics**
   - API response times (/usage-forecast)
   - Error rates
   - Redis cache hit rate
   - Database query performance

### Dashboards to Create

**Conversion Funnel** (Mixpanel/Segment)
```
subscription_page_viewed
  → billing_cycle_toggled
    → feature_list_expanded
      → upgrade_cta_clicked
        → upgrade_started
          → upgrade_completed
```

**ROI Impact** (Mixpanel/Segment)
```
Users who saw ROI calculator vs. those who didn't
  → Compare conversion rates
  → Measure average savings shown
  → Track payback period distribution
```

**Usage Forecast Accuracy** (Custom Dashboard)
```
Predicted breach dates vs. actual breach dates
  → Calculate MAPE (Mean Absolute Percentage Error)
  → Identify metrics with highest prediction accuracy
  → Adjust growth rate calculation if needed
```

## 🔧 Troubleshooting

### Issue: Plans Not Loading

**Symptoms**: Spinner shows indefinitely, error message appears

**Solutions**:
1. Check API endpoint: `GET /plans`
2. Verify CORS headers allow frontend domain
3. Check browser console for network errors
4. Verify authentication token is valid

### Issue: Usage Forecast Empty

**Symptoms**: Usage metrics show 0/null, no trend data

**Solutions**:
1. Ensure cron job is running (see checklist above)
2. Check Redis contains usage history keys
3. Run manual tracking: `python3 scripts/track_daily_usage.py`
4. Wait 7 days for sufficient data (minimum for growth rate calculation)

### Issue: Translations Not Working

**Symptoms**: Text shows as "features.xyz" instead of translated text

**Solutions**:
1. Clear browser cache
2. Verify translation files exist:
   - `frontend/src/locales/en/subscription.json`
   - `frontend/src/locales/es/subscription.json`
   - `frontend/src/locales/eu/subscription.json`
3. Check i18next configuration
4. Inspect network tab for 404s on translation files

### Issue: Analytics Not Tracking

**Symptoms**: No events in analytics dashboard

**Solutions**:
1. Check `localStorage.subscription_events` for local tracking
2. Verify analytics snippet is loaded: Check `window.analytics`, `window.mixpanel`, or `window.gtag`
3. Check browser console for analytics errors
4. Verify analytics write key/token is correct
5. Check ad blockers aren't blocking analytics

### Issue: Professional Tier Not Prominent

**Symptoms**: Professional card looks same size as others

**Solutions**:
1. Check CSS classes are applied: `scale-[1.08]`, `lg:scale-110`
2. Verify `popular: true` in plan metadata from backend
3. Clear browser cache and hard refresh (Cmd+Shift+R or Ctrl+Shift+R)
4. Check Tailwind CSS is configured to include scale utilities
