## Architecture

### SWIG Backend (File-based) -- Default

- **Status:** Stable
- Direct pcbnew API access via KiCAD's Python bindings
- Requires manual KiCAD UI reload to see changes
- Works without KiCAD running
- Auto-saves after every board-modifying command

### IPC Backend (Real-time) -- Experimental

- **Status:** Functional, 21 commands implemented
- Real-time UI synchronization with KiCAD 9+
- Requires KiCAD running with IPC API enabled
- Automatic fallback to SWIG when unavailable

### Hybrid Approach

The server automatically selects the best backend:

- IPC when KiCAD is running with IPC enabled
- SWIG fallback when IPC is unavailable
- Some operations use both (e.g., footprint placement)

---

## Platform Support

### Linux -- Primary Platform

- KiCAD 9.0 detection: Working
- Process management: Working
- Library discovery: Working (153+ libraries)
- IPC backend: Working

### Windows -- Fully Supported

- Automated setup script (setup-windows.ps1)
- Process detection via Toolhelp32 API
- Library paths auto-detected
- Troubleshooting guide available (WINDOWS_TROUBLESHOOTING.md)

### macOS -- Community Supported

- Configuration provided
- Process detection implemented
- Library paths configured
- Needs community testing
