🚀 What's Ready to Use

Backend API Endpoints (All Live)

User Management:

• POST /api/users/invite - Send operator invitation

• List users, send invitations, manage roles
• See guide for complete code example

3. Map Inspection Modal

• Update to POST to /api/maintenance
• Include hydrant_id, maintenance_type: 'inspection'
• See guide for complete code example

4. Reports Page

• Replace hardcoded data with /api/dashboard/stats
• Use compliance endpoint for detailed reports
