• firmware.platformio-pin-contract: Checks a PlatformIO-style firmware pin contract against BoardReadyOps pinmap firmware labels.
• firmware.arduino-pin-contract: Checks an Arduino/C #define firmware pin header against BoardReadyOps pinmap firmware labels.
• firmware.zephyr-pin-contract: Checks a Zephyr firmware pin contract YAML against BoardReadyOps pinmap firmware labels.
• firmware.esp-idf-pin-contract: Checks an ESP-IDF firmware pin contract YAML against BoardReadyOps pinmap firmware labels.
• firmware.stm32cubemx-pin-contract: Parses a STM32CubeMX .ioc project file and checks GPIO labels against BoardReadyOps pinmap firmware labels.
