"""Cross-language golden test: the app's TCX is accepted by the real verifier.

The workout app (Dart, ``lib/services/tcx_codec.dart``) writes the TCX files
the PC credits. Each language's own round trip passes happily while the other
side's parser disagrees, so the Dart twin
(``stronglift_replacement/workout_app/test/services/tcx_golden_fixture_test.dart``)
encodes ``fixtures/run_tcx/golden_tracks.json`` and compares the result byte
for byte with the ``.tcx`` files checked in next to it. This test feeds those
SAME files to the real ``RunnerUpVerificationMixin`` -- date glob, parser,
run validation and walk summing -- and asserts the km / minutes the JSON
promises. Everything runs on a temporary drop directory: nothing here reads
or writes ``~/data/cloud/RunnerUp``.
