mikkeli	6a7de03773	obd-poller: OBD-II mode 01, the single CAN writer; recorder keeps its values ... obd-poller asks 0x7DF for the nine obd2 signals, only while the bus is alive, and publishes envelopes stamped with the reply's kernel time. The recorder subscribes to yukart/vehicle/* and writes vehicle.ndjson beside the frames. Tested against a fake ECU on vcan0.

mikkeli	0c45e68045	orin-status: the Orin's health on the bus ... Temperatures, CPU/GPU load, memory, module power, fan, WiFi/LTE/tablet links and the UPS battery (INA219, read-only) as envelopes on yukart/host/<signal>, once a second. Built natively on the development Orin. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01DDwfd6Ki8UfG4hK6W5YpJz	2026-10-12 16:33:31 +09:00
mikkeli	1f678fe87f	Add recorder: raw CAN and GNSS sessions with failsafes and a storage bound ... 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.
