Lab Architecture

Labs follow a common lifecycle:

1. LabLauncher component provisions the environment on Izar or Tarn nodes
2. SessionBar displays countdown timer and session controls
3. TerminalEmbed (xterm.js + WebSocket) or VNCEmbed (noVNC) provides access
4. ChallengeTracker tracks progress through lab objectives
5. DocumentationPanel shows contextual docs alongside the lab

The system uses dual-node failover (Izar for local, Tarn for remote) with HMAC-signed API calls for security. If no physical infrastructure is available, labs fall back to simulation mode.

Lab Types

VM	VNCEmbed (noVNC) + TerminalEmbed	Proxmox on Izar/Tarn
