I was in this kind of situation once, and it was basically a setup for subsequent termination.
My advice is that you should have a 1 on 1 with your manager ASAP, and ask them to be upfront with you about things.
In the end, if someone says you failed to deliver on time, or you failed to follow instructions, or you failed to write code as it should be written, you can't do a thing about it. If you've been tagged as a "failure", arguing your point or trying to say they are wrong will go nowhere if they already have made up their mind.
If your manager is "managing up", then you are not in a good place as you will become a scapegoat for problems. If your manager really has your back and will defend you, you are in a better place.
