"""RunnerUp exports are read from the WebDAV drop directory, phone optional.

RunnerUp's WebDAV synchroniser uploads every export to dufs on this machine
(``RUNNERUP_WEBDAV_DIRS``), minutes after the run ends, and endurain-import
moves them to ``processed/``. Reading those files credits the run without the
phone being adb-reachable: on 2026-09-16 the TCX was on disk at 20:08 and the
phone was only plugged in at 20:25.
