I just recently ordered my notes too. Nothing had started on our file, but some people were nice enough to help us understand them. The things you wanna look for is the info on the first page. Update date is the last update on your file. Group # if blank then awesome if not it is possible you may be requested to come in for an interview. The Notes section on the last couple of pages are also very important. From the notes of the officer you can get a good idea of how they perceive your relationship to be (genuine or not etc). Check out the due dates assigned to Eligibility, criminality, and security. This just gives you an idea of what their internal deadlines are, they are not set in stone and work can be wrapped up before these due dates so not to worry.
Yes even though security and criminality appear to not have been started, the truth is they don't write anything there, so they might be happening simultaneously. It sounds very promising what you have described, so all the best
