Givnup, I don't see where you responded with the outcome several yeas ago after recommendations were made for you to seek personal counseling with MB for this issue. How did that turn out?
RR, the advice given to Givnup was that if POJA is not being honored, the process may not have been done correctly, and the spouse violating POJA may not have been truly enthusiastic about the agreement.
Another issue could be that she doesn't feel safe being open and honest during POJA negotiations.
Are you sure POJA negotiations have been "pleasant and safe"?

I assume that at least some of the POJA violations are happening where she makes you aware in some way that she has changed her mind before she actually takes action. How do you respond in those cases?
In order to truly say that your wife refuses to follow POJA and is acting independently, you have to remove any barriers that may be caused by your own behavior, for a period of time. You also have to demonstrate care and exercise POJA properly on your side, even when she does not. When she sees you doing this, it DOES influence her in a positive way.
POJA is an essential, foundational policy. You cannot succeed in having an integrated marriage of care for each other without it.
Givnup, threats regarding kids and punitive actions, etc. are selfish demands. Have you read Love Busters? Has your wife?
"Complaining too much" indicates that you may be using complaints as a selfish demand - an attempt to badger, educate, or change her. That won't work. Neither will "keep my mouth shut".
On suggestion: When you come with a properly worded complaint, given in the right attitude, do you also bring a possible solution or two to the table? That was a big one for me that helped me check myself when it came to SD complaints. Generally if I did not have a solution in mind, my motivation for complaining tended to be one that would not work.
Givnup, if you are still in the same boat after almost three years, consider posting more about what is going on and get some direction.
I think that separation would be the ultimate destination if your wife is truly as you indicate. But feeling like you have done everything right, and the reality can be two different things. Especially if you are looking at the situation with tunnel vision without any outside perspective.
In my own case, that was very much true. I was putting a lot of effort into doing things incorrectly, incompletely, and spending a lot of energy on emotional reactivity instead of solving problems.
