Phase 3 — Discovery & Monitoring: - Network scanner: nmap wrapper + mock fallback, fingerprint service (35 signatures) - Status checker: ping/http/https/tcp/ssh/prometheus/health per-node checks - APScheduler: status checks every 60s, WebSocket broadcast - WebSocket /ws/status: live node status updates to frontend - Sidebar panels: Pending Devices, Hidden Devices, Scan History - Auth token persisted to localStorage (survive page refresh) - 24 new backend tests (scan flow + status_checker) Phase 4 — Polish & Deployment: - Auto-layout: Dagre hierarchical TB via Toolbar button - Export PNG: html-to-image download via Toolbar button - Scan config modal: CIDR ranges + check interval, GET/POST /api/v1/scan/config - Dockerfile.backend (Python 3.13 slim + nmap), Dockerfile.frontend (nginx) - docker-compose.yml with data volume and NET_RAW cap for ping - scripts/lxc-install.sh: Proxmox VE systemd bootstrap - README.md: quick-start, config reference, stack overview
