ARCHITECTURE
================================================================================

Frontend (Port 3000)
  ├─ Layer 1: TypeScript Parser (instant syntax validation)
  └─ Layer 2: LSP Client (semantic validation, 300ms debounced)
       │
       │ WebSocket (Socket.IO)
       ↓
Backend (Port 5001)
  ├─ Flask + Python LSP Server
  ├─ TactusValidator (semantic validation)
  └─ File operations (read/write)

================================================================================
VERIFICATION
================================================================================

1. Check Monaco environment:
   grep -A 5 "MonacoEnvironment" frontend/src/main.tsx

2. Check WebSocket port:
   grep "localhost:5001" frontend/src/Editor.tsx

3. Check model lifecycle:
   grep "isDisposedRef" frontend/src/Editor.tsx

4. Check connection handling:
   grep "isConnected" frontend/src/LSPClient.ts

5. Run the IDE:
