IOW, you're looking for proof but disregard all facts as "cloudy". You know, it's a pure joke for you to refer to yourself as a scholar.
The Virginia reservation refers to the people of the United States, not the people of Virginia. That is not cloudy, that's opaque.

Setting aside the gratuitous insult, may I say that the Virginia "reservation" sounds to me like a recognition of the natural right of rebellion against injustice, not a positive right under the Constitution, and, as WhiskeyPapa has already noted, it seems to be said of the people of the United states, not the People of Virginia.
That the text is genuine is, indeed, a fact. What it means is, IMHO, probably unhelpful to those who would make the Union a mere alliance.
I hope that clarifies my previous post.
