  # The suite is split by directory so it finishes in a few minutes, and so a check's name says
  # which area broke.  The groups are balanced by test time; `rest` runs everything the others do
  # not, so a new directory is tested before anyone assigns it.  A path added to any other group
  # must also be added to `rest` as an --ignore, or its tests run twice.

  # Do the API and the frontend's test fixtures still agree?
  #
  # `api-tests` runs these too, as part of the whole suite.  This job exists for the signal:
  # fixture drift is silent by nature -- the frontend suite passes against a body the API stopped
  # sending -- so it is worth a check whose name says what broke, failing in under a minute rather
  # than somewhere inside seventeen hundred results.  It needs no ffmpeg or catdoc.
