⚠️ KNOWN LIMITATIONS

1. Charts Not Fully Implemented

Status: INCOMPLETE Reason: Focus was on structure and all critical audit issues Current State: Chart.js is loaded, containers are ready Required: Implement chart initialization in dashboard.js or separate charts.js

2. Advanced Search Not Functional

Status: PLACEHOLDER Location: unified_dashboard.html:53-56 Current State: Search input exists but has no backend wiring Required: Implement search logic and backend endpoint

3. User Menu Not Implemented

Status: PLACEHOLDER Location: unified_dashboard.html:66-68 Current State: Button exists but no dropdown Required: Implement authentication and user profile features

4. Modal Forms Not Implemented

Status: INCOMPLETE Example: Create Pool button shows alert instead of modal Location: dashboard.js:414-416 Required: Implement modal component and form handling

5. Some Admin Settings Client-Only

Status: PARTIAL Current State: Feature flags use backend, other settings use localStorage Recommendation: Create backend endpoints for all settings

🚀 DEPLOYMENT NOTES

Browser Support

  • Modern Browsers: Chrome 90+, Firefox 88+, Safari 14+, Edge 90+
  • Mobile: iOS Safari 14+, Chrome Mobile, Samsung Internet
