Well I don't know where they might look but they have to try and find anything that they could deny you for.
As far as 90 days. It says that they must act on your application within 90 days. it never says that it must be completed within 90 days. They have obviously acted on your so now they can take as long as they want.
I wonder if they consider cashing your check as acting on it.
At least for me, cashing the check and sending of my info to CJIS is all that has been done so far.
