It's difficult to review auto-generated changes like these, but the DCA run shows taint reach going up a little and nothing is broken. 👍

I agree. And as we scale things up it will make even less sense to try and manually verify them. I've merged |

This is just rerunning the model generator for
coreandstdand adding a manual value flow summary forString::from. I think that one might've been lost due to primitives not being extracted and hence method resolution now working ideally for builtins.
