Correct, at least in broad strokes. That is exactly how the system of law functions. Ultimately, it is up to the court system to determine whether laws are or are not in accordance with Constitutional law and existing precedent, or not, and up to the Congress to create new laws should the need arise. Not only does this apply to treaty-making, it very specifically applies to treaty-related law, as one of the ten special categories that fall under the Supreme Court's purview in the first place.
No, that is not the case. But let us assume, for the sake of the argument, that that is how the system works - time-backwards causation!!!
Here are some of the consequences:
First, we do not know, for example, whether banning interracial marriage is unconstitutional. You do not know that because maybe a future SC will make it constitutional by their say so, and if so, it will do so retroactively. And maybe that will not be canceled by a further future SC.
Second, justices are very confused about their own job. They believe that sometimes, the SC makes mistakes. They say so in their dissenting opinions. But while the SC makes mistakes, the mistakes need not be related to the arguments made in the dissenting opinions. Rather, the SC makes mistakes whenever they say X is constitutional but the last SC to decide on the matter will declare it unconstitutional, making it unconstitutional backwards in time.
Third, there is no democracy. Congress does not matter. What is legal, constitutional, etc., is whatever the last SCOTUS to rule on the matter will say. Are the treaties unconstitutional? We do not know. It might be decided in 100 years, with retrocausal effect.

In the theory above, it is not the court system, but the SC that makes the last ruling on the matter. It might be 100 years or 200 years into the future.
But in reality, the courts ascertain whether something is legal, constitutional, etc., and make a ruling. Sometimes they get it wrong, though usually they get it right. When the SC gets it wrong, the system has no further court to appeal to. Given that justices are not likely removed, then justice is effectively denied. It happens, and no system is perfect. But it works as I have explained.

It should be noted, though, that this does not necessarily extend to making actions in the past retroactively criminal in character; there are strict and severe limits on such.
That contradicts what you said before, though. Remember, the courts decide. Well, the last SC does, but let us simplify. For example, a future SC might decide that some actions in the past were criminal, and that the so-called "strict and severe limits" were a misinterpretation. So, they make actions retroactively criminal (time travel has this sort of funny consequences).

The courts determine what the law is, not what it was.
That contradicts what you said just above. But let us forget your previous claims, and say the system is like you say now. Remember that in
Pace v. Alabama, the SC said that the Alabama statute banning interracial sex was constitutional. So, they were correct, because they cannot be wrong - they are the SC!
So, it was legal to ban interracial marriage, and Tony Pace and Mary Cox were lawfully convicted. However, if the SC had decided otherwise, then the law would have been unconstitutional and Pace and Cox would have been unlawfully convicted. Because the SC makes what is unconstitutional and what is not so. Well, at the time of the ruling. Now, the time of the events was actually prior to the rulings, so the SC could not say what the law was back then...so, we get further absurdity.
