No design changes were made; the project is still empty. Building the ESP32-S3 anti-theft alarm with an RD-03D radar and GSM SMS/call module requires AI execution features, but no ACUs are currently available.

Remaining work: confirm the GSM module and power source/battery requirements, then create and verify the schematic, power system, programming interface, PCB layout, and firmware pin map. Recharge ACUs to continue.
