I guess that was a little terse, and there's more I'd like to say on
this. I'm not faulting you here, but it's really weird to me that
there is suddenly this implicit assumption that a company doing
bug-hunting stuff should be credited for finding a bug now that
they're AI-industry-affiliated, when that's not how anything worked in
the past.

We have never credited proprietary static analysis or fuzzing tools
uses to find bugs in the past, and the reason I haven't is because I
do not want an immutable git log to be an advertising platform serving
the valuation of a business and encouraging the use of proprietary
tools.

We sometimes do credit individual people who reported a bug if they've
been involved in actually helping understand and fix it, especially if
it's important/security-relevant. But this kind of credit should
reflect a pro-social engagement with the community not just checking
what their slop-bot told them and leaving us to figure out whether the
report is even valid and how to write a test case to reproduce it.
