`r` in the GNSS App (or `gnss track start|stop`) records a Track to /gnss/tracks/YYYYMMDD-HHMMSS.gpx: a point every 5 s once moved 5 m (lib/gnss/track, 7 tests: haversine, the rule, GPX text, the file name). It keeps recording with the App closed, shows REC in the Status Bar, and announces start and stop with a Toast. It needs a card and the time; switching GNSS off stops it. Tracks are written like Captures: past 90 % card usage, until full. Storage Clean-up gets a GNSS tracks category. A Track cut short by a reset or power loss has no GPX footer; the GNSS Service closes such files at the next boot. Verified on the device: a recorded Track and one interrupted by a reset both parse as GPX 1.1 on the PC.
