* Artwork and audio by URL or by direct upload, checked automatically.
* `validate` and `submit`, with the same rules as releases created in AMM Distro.
* Catalog transfers: group already-released releases and submit them together.
* Release status, store links and file status on every release.
* API access turned on per account; account admins create keys in **Settings → API**.
