Dockerized build system (Dockerfile, docker-compose, build.sh) with Pico SDK cross-compilation. Modular CMake split into project_config, mcu_config, and sources_config under cmake/. Component architecture following inc/prg/cfg convention: STD_TYPES, MCU_USB, HAL_COM, APP_CLSW, SYS_ECU. Full call chain SYS_ECU -> APP_CLSW -> HAL_COM -> MCU_USB verified end-to-end on RP2040-Zero hardware over USB-CDC. Includes flash.sh for automated .uf2 flashing on macOS and devcontainer config for VS Code. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
