# Funkwhale 2.0.11: a channel (an actor of its own) and its tracks. alice_funkwhale follows the channel; a track uploaded
# to it arrives as Audio with its file and duration; its deletion; the unfollow. Funkwhale's API takes fwuser's OAuth
# token; a track is a fresh tone made by ffmpeg in its own container (Funkwhale skips a file it already has); what it
# holds is read from the shared Postgres (database funkwhale).
