ai.newnal.illi.media.getOriginal

Server-to-server only. Media fetches an active registered original using a media service JWT with this method as lxm. The response streams the PDN blob with Content-Type and Content-Length. An original whose deletion is in progress answers 503 OriginalUnavailable (retry later); only a missing, deleted or unregistered original answers 404 NotFound, which media treats as final.
