Two inspection fixtures for "Your workout reached Strava, but the map did not".

track-with-points.gpx     7 timed <trkpt> elements (same geometry as the export practice file).
track-without-points.gpx  A <trk> with an empty <trkseg>: the file has track structure but
                          no track points. This shows what that representation lacks; it
                          does not show why (exporter, permission or format choice).
Case 3 in the article (route hidden by map visibility) is a display setting, so it has no file.
Hand-written synthetic files; validated against the GPX 1.1 schema; not uploaded anywhere.

Editorial validation: the supplied GPX files passed offline XSD validation on 20 October 2026. This checks file structure, not provider acceptance or real recording provenance.
