So would this be 1600 commits and one of which fixes the bug (which might be easier with commit messages?) or is this a diff between two revisions, with 1600 chunks, each chunk a “document” ?

I am trying to grok why we want to find the fix - is it to understand what was done so we can exploit unpatched instances in the wild?

Also also

“identifying candidate functions for fuzzing targets“ - if every function is a document I get where the list of documents is, what what is the query - how do I say “find me a function most suitable to fuzzing”

Apologies if that’s brusque - trying to fit new concepts in my brain :-)
