Records every received V2X message (CAM, DENM, SPATEM, MAPEM, VAM) into one SQLite file per run, with a timestamp, the phone's GNSS fix, the OBU's GNSS fix where there is one (CiT One), and RSSI where the hardware reports it (ESP32-C5). Works on both hardware paths: V2X_RX frames from the ESP32 link, and the raw v2x/rx plus processed v2x-uca topics over MQTT. The UPER bytes are stored untouched; CAM, DENM and SPATEM also get a few decoded columns. A foreground service keeps it recording with the screen locked. Subscribes to v2x/rx/mapem so MAPEM is received on the CiT One. The current ESP32-C5 firmware forwards only BTP ports 2001, 2002 and 2004, so MAPEM and VAM appear in an ESP32 log only once it accepts 2003 and 2018. Checked on a Pixel 9 Pro against a simulated car and an RSU: 10 minutes with the screen locked and forced deep Doze, no gaps, files pass integrity_check.
