When multiple devices share one Arduino (e.g. `AnalogInputDevice` + `DigitalIODevice` on same port), both call `port_registry.get_layer(port, baud)`, get same `ArduinoLayer` instance. Never construct `ArduinoLayer` directly in device code. +**Shared serial port** — `api_layers/port_registry.py` holds module-level `port_registry` singleton.

Never construct `ArduinoLayer` directly in device code. **Device auto-discovery** — `DeviceRegistry._discover()` scans `devices/` with `pkgutil`, imports every module, registers any class subclassing `BaseDevice`. New device type = drop file in `devices/`, no registration needed. |
