GpxStore#save converts eagerly, so "cached" is true for nearly every file in the tree already — badging that was just noise. Flipped to PENDING_ICON, shown only for the rare case: a .gpx/.fit dropped straight into data/gpx/ on the filesystem, bypassing the app, and not yet opened. Also add an explicit download button next to delete (DOWNLOAD_ICON) — the file name itself has been a download link since the last commit, but isn't obviously clickable at a glance.
