With job_id the file is that studio job's take (the account's own job, 404 otherwise; a file not of the job's kind is 400): it fills the copy the account was making from the provider, and a take kept already answers 200 with its stored file and keeps nothing more, so one take is one stored file. A 404 with code storage_off while stored media is switched off (ANTIMATTER_STUDIO_STORAGE). The signed in account; same origin only.
