- **🚀 58-second End-to-End Deployment**: From natural language intent to fully deployed network slice

- **📊 Thesis-Validated Performance**: eMBB (4.57 Mbps), URLLC (6.3ms RTT), mMTC (2.77 Mbps)

- **🔄 GitOps-Driven Automation**: Nephio-based package generation and Kubernetes orchestration

- **🌐 Multi-Site Connectivity**: Kube-OVN overlay networking with intelligent placement

- **📈 Production-Ready CI/CD**: Modern GitHub Actions with 100% compilation success



### Core Innovation
