The quick test doesn't show a lot - by out straight asking if this is a security patch, it implies and guides AI to have output more probably to agree on this assumption. A confusion matrix is more useful. Nonetheless of course this is not a detailed ai capability testing blog.

I agree it is not much additional evidence! If someone wanted to try running the same test on a series of N commits from that list including this one I'd be very curious to see the answer!

Yeah, ideally we would need the phi coefficient (aka MCC, the binary Pearson correlation), which can be calculated from a confusion matrix of yes/no LLM classifications for all kernel diffs. (Number of true positives, true negatives, false positives, false negatives.)
