Wow. This is incredible. Turning the entire field of mathematics into a formalized and connected system. An index of mathematical understanding. All fields will undergo this change!!!

My man Terrance Tao, I hope to contribute to your symphony of progress.

If the interrelationships of this are also exposed and searchable, if it can build many bridges inside itself, then this is truly the cipher key to all that can be known.

Isn’t this kind of a recursive problem where you now have to prove your proof that their proof proves their claimed statement?

It's not a proof. You check that the mathematical ideas expressed in the claimed statement are the same as the mathematical ideas expressed by the Lean repository.
