I think USCIS has taken a decision/action on your case in response to the mandamus lawsuit you filed. You will need to wait for the notice and then work with your lawyers if the decision is against you for e.g. notice of intent to deny ( NOID) your AOS for whatever reason.
Did you ever see a case status update on the USCIS website that says something like ‘Information was received’ after you sent the requested information/documents for the RFE you received?
