Cross-platform (macOS + Linux) C++17 CLI that extracts a Betaflight FC's blackbox log in one command: auto-detect the serial port, read craft_name over the Betaflight CLI, send `msc` to reboot into USB mass storage, wait for the volume to mount, copy btfl_all.bbl to <craft_name>_<YYYYMMDD>_<HHMMSS>.bbl, and eject. Native throughout (termios serial, getmntinfo/proc-mounts mount detection, DiskArbitration/umount eject); the only subprocess is the Linux udisksctl eject fallback. Includes CMake/ctest build, unit tests for the pure logic (naming, craft_name parsing, mount diff, serial via pty, CLI parsing), README with a manual hardware integration procedure, and design/plan docs.
