Deck post twisting and pulling away from beam

I hired a contractor to build a deck about 2 years ago. He clearly used very green wood and didn't use carriage bolts to attach the posts to the beam. As the post dried, it twisted and pulled away from the beam. See attached photos. I have a few questions:

1. How worried should I be? I assume it's done drying/moving and so won't get any worse, right?
2. Do I need to replace the whole post?
3. Should I add carriage bolts now?
4. If so, how many? Just one or two per post?
5. Is my goal to tighten the nut down enough to pull them back together, or just prevent them from separating any further?

It likely has finished warping and it looks like you still have enough support. So you could put a bolt there to hold it in place. It will not pull back in unless you can drill oval shaped holes and twisting the post is doubt.

Treated posts are always wet so this can always happen so if you change the post you may want to buy it and let it dry first or just use 4 2x6s for a better chance of them holding each other straight.
