> IIUC, the direct binary access download logic doesn't actually verify that 
> the requested blob is available in the cloud before creating the signed 
> download URI.  It is possible that a user could request a download URI for a 
> blob that is "in the repo" but hasn't actually been uploaded yet.
> We should verify this by uploading a new blob, preventing it being uploaded 
> to the cloud (retain in cache), and then request the download URI.  We should 
> get a null back or get some other error or exception; if we get a URI it 
> would return an HTTP 404 if the blob is not actually uploaded yet (maybe this 
> would also be ok).
