Reads SocketCAN and gpsd directly. Sessions start on the first frame or on 'ctl start', end after 15 s of bus idle or on 'ctl stop'; blips under 3 s are discarded. candump -L chunks fdatasync'd every second and zstd'd once closed; oldest sessions deleted to stay under 50 GB / above 20 GB free. Kernel and queue drops, link changes and clock steps are recorded as events. Bench-tested on vcan with the first car capture (byte-identical) and installed on the car Orin as yukart-recorder.service.

needed.
