@* Mix-medium fields. The high-res waveform is a server-side derived datum: the CMS fires a body-less
   trigger (POST api/release/{id}/mix/waveform) after the release exists, so generation is managed
   per-row in the Mixes browser, not at create time. On upload the trigger is fired automatically; this
   section states that contract and carries no input of its own. *@
