"The begining of the universe was the big bang" is an example of such fact. Now, this sentence can and must be reviewed but the index over "how did the universe began" would keep track of it in that hypothetical platform. So, until it's reviewal, the sentence can be recognized as canonical.

An approximation to this goal can be found in the page of 'papers with code' where you can see the SOTA for a given set of problems (I've used for AI) so the question "what's the most performant model for face recognition" can be answer and keep track of over time. It may not be comprehensive and I can only account for it's AI coverage, but it resemblance some aspects of the general idea.
