“All shapes” is the phrase that is analogous with “children born within the jurisdiction” ... the extra detail you came up with doesn’t change the obvious fact that equilateral triangle is only defined by the criteria in the preceding sentence.
But it's not, because there's no restriction on "all shapes." It doesn't say "some authorities go further and include as citizens all children," it says "children who meet a certain criterion." Your analogy isn't working.
But let's say you tweak it so it works. You have to admit that my version is just as valid as yours. Which means that the multiple courts who read Minor the way I do aren't "wrong," as you keep insisting. They just disagree with you.
