oh, hmm, agree on using common-accessioning API key, but also, not sure how best to provision it. i think that's usually something we'd provide via vault and puppet, or maybe shared_configs before we standardized on vault. but i'm not sure how to best provide that to the container. i think for now we keep providing by hand via .env file, and then eventually some terraform magic will configure the env var?

• test (how to force an exception?)

feed it a corrupted media file (if it's easy to corrupt something so that it looks like media, but fails STT extraction)? feed it bad whisper parameters? 🤷
