Yes I passed eligibility too. My pattern is very similar to yours. I got a GU one day before the CV request was sent to me. When I saw that request, I called them and they confirmed that I had passed all but security.
Also, you don't need to be puzzled. Even without calling them, you can be sure that you had passed eligibility by the time you saw this ADR , because all those additional documents are clearly linked to security check, and they only initiate security after we have passed all other stages.
Call them tomorrow to get a understanding of that form and keep me posted on any development about your application
