- Fix class diagram: use aggregation (o--) for BleakScanner and MQTTClient - Split sequence diagram into separate files for clarity - Add sequence_startup.puml for gateway initialization - Add sequence_data_collection.puml with error handling - Use collections for BLE broadcaster to reflect multiplicity - Remove loop construct — gateway reacts to packets, ignores intervals - Add discard of unknown UUID packets - Add handling of invalid sensor values
