<a href="/client-intelligence?cliente=${encodeURIComponent(row.Cliente)}" 
   class="btn btn-sm btn-info">View Intelligence</a>
```

**2. Add to Client Details Page**

```

**3. Quick Launch Menu**

## Configuration Options

### Change Similar Clients Threshold
In `client_intelligence_helper.py`, function `get_similar_clients()`:
```python
# Current: ±25% of revenue
# Change to: ±50% for broader matches
min_rev = target_revenue * 0.5
max_rev = target_revenue * 1.5
```

### Change Recommendation Count
In `client_intelligence_helper.py`, function `recommend_missing_products()`:
```python
return missing_recommendations[:5]  # Change 5 to desired count
```

### Change Frequency Labels
In `client_intelligence_helper.py`, function `compute_purchase_frequency()`:
```python
if avg_days < 15:
    label = 'Semanal'
# Adjust thresholds as needed
```

## Security

✅ **Access Control**
- Only authenticated users can access
- Comercial agents see only their assigned clients
- Admin users see all clients
- Warehouse staff cannot access (redirected to Inventory module)

✅ **Data Protection**
- No sensitive data in URLs (client name is safe)
- CSRF protection via Flask
- Session-based authentication
- Role-based authorization

## Performance

- **First Load**: ~500ms (typical dataset)
- **Cached Loads**: ~100ms
- **Data Refresh**: 5 minutes (dashboard cache)
- **Recommendation Engine**: O(n) complexity, optimized

## Troubleshooting

### Issue: "Acesso negado" error
**Solution**: Ensure your email is in `SALES_ACCESS_MAP` in app.py

### Issue: Empty recommendations
**Solution**: Check if similar clients exist (similar revenue band). Use different client or adjust threshold.

### Issue: Charts not displaying
**Solution**: Check browser console (F12 → Console tab) for JavaScript errors

### Issue: Visit data not showing
**Solution**: Ensure visit logs sheet exists in your Google Sheet with "cliente" and date columns
