L1: Visual Cockpit

  • • Backstage React Plugins with real-time SSE streaming
  • • Native A2UI VDOM Mesh (60 FPS) & bi-directional GUI telemetry
  • • Decoupled from K3s API server load

L2: Google AX & Gemini 3.5 Baseline

  • • Gemini 3.5 Pro & Gemini 3.5 Flash baseline LLM reasoning
  • • Single-Writer controller with active etcd lease locks
  • • Closed-Loop Google Antigravity verification engine

L3: Isolated Substrate & GCP Integration

  • • gVisor (runsc) user-space kernel & eBPF syscall filtering
  • • Instant Session Teleport (<150ms) with memory snapshots
  • • Ephemeral Polecat actor multiplexing & GCP Cloud Operations
