$ plex-axi doctor --help
environment: default
exit: 0

usage: plex-axi doctor
description: Check the environment, the server, the music library and its filters
access:
  read-only - this command cannot change anything on the server
flags{doctor}:
  (none)
note:
  exits non-zero when any check fails, so it works as a CI or hook gate
note:
  `sonic analysis` is reported and never fails the run: a library with it off is healthy, and `similar` simply has nothing to return
note:
  a rejected token is reported as invalid or expired separately, because Plex answers 401 to both and only the response text tells them apart
examples:
  plex-axi doctor
  plex-axi --section 'Example Music' doctor
