Oh that is really fascinating, thank you. That has some really interesting implications for dependency management that I will have to think through. It sounds like that implies some really useful tree properties on dependency checking, like if the part of the program you are relying on matches a certain hash you don't need to check down the chain because you can be sure the rest of the nodes are as you expect. Much appreciated!
