Have you ever received ANYTHING from CIC? Your AOR email, would have a file number along with your personal UCI. Sometimes, they don't work, from what I've heard, but I didn't have that issue. Anyway, it would seem that if your wifes eCas is showing 'In process' with the line 'Medical Recieved' you are indeed nearing your finish line. If this IS the case, then I would fill out an OWP application for her to either get a job, if this is what you both want, or at the very least will put her back into status. If her application is in process then you do indeed have AIP and she would qualify.
If she doesn't really want/need to go to work, then her status should be fine. It is not likely that anyone is going to come knocking on your door to deport your wife, especially since you already do have AIP and she is almost finished processing.
Good luck!
