Cause and effect in changing times

A retroactive citation is not reverse causation. Even from here to here it is not clear whether this is reverse causation, and this must be discussed in the laws of conditionality and choice. Everything is detailed there.

My intuition from my years in the yeshiva is that we do assume some kind of halachic meta-reality (whether in impurity, or in other types of vegetables) and in fact even if it is not an ontic reality, after all how things work in the ideal world of halachic law.
. There is a classic investigation in the yivamos (seen right in the first ones) whether the yivam is what creates the connection between the yivam and its yivam before the yivam (the other side is irrelevant), how is it possible that a late yivam creates an early connection.
On second thought, it can be said that the creator of the connection is not the yivam in practice, but in power and it preceded the connection.

It is clear that the obligation to perform does not create a relationship. We are talking about the obligation to perform that exists in principle.

May the Lord grant him a great reward, a great rabbi, after me, I lectured in the Treasury of Wisdom, Rabbi Amiel himself speaks of this “in the cause and the cause” itself, and he understands that the universe itself is the cause, and goes on to say that there is no problem with temporal precedence.
Regarding the first issue, isn't it simple for the Rabbi that the Halacha assumes a halachic metaphysical reality?
