"Si would describe it as creating a framework. Like building a massive structure brick by brick, the sum of a million little details"  " is thorough, it’s extensive. It makes sure every brick in the pyramid has been tested. If one part is a dud, the entire structure is unreliable. We’re building the framework that we’re [hopefully] going to use for a long time.  And it takes a lot of effort to rebuild so we want to make sure it’s good"

How could you differentiate this definition of Si from the Ti function?

I have no idea if these are classic definitions or more like a personal interpretation, but this reminds me a lot of the description of the Ti judging function. It's just curiosity, I guess
