Requirements Document¶

Introduction¶

The NexusAI Toolkit is an enterprise-grade management platform that enables customers to deploy modular business capabilities into their own cloud infrastructure (AWS/Azure/GCP/On-premise). The system provides a guided, license-controlled deployment experience with comprehensive operational tooling for monitoring, updates, and lifecycle management. The toolkit supports both Progressive Web Application (PWA) and Electron desktop application delivery models, with multi-factor authentication, role-based access control, and per-capability license validation.

Administrator: User role with full system access and configuration privileges
Operator: User role with limited deployment and monitoring privileges
Viewer: User role with read-only access to dashboards and reports
MFA: Multi-Factor Authentication using TOTP, SMS, or email verification
