Hi, in-land spouse sponsorship application status online shows that a decision has been made, medical, security, and background has been completed as well. What does this mean?

Nobody here either knows what mail you've received, or worked on your file.
If you didn't receive any procedural fairness letters, or interview requests, it's probably a positive result. If you were sent requests and ignored them, it's probably a negative result. If you had an interview, you should have had an indication from the case officer what they were recommending.
