Day 0: the owner deletes the workspace. Nobody can open it any more, but it can still be restored.
Day 30: the workspace is purged. Its files and database rows are removed and its key is destroyed, so nothing it held can be decrypted again.
Within 35 days: encrypted backups that still contain it age out.
