I don't believe I was inverting responsibilties, but sorry if you thought I was.

Yes, there is a bug in something I committed which I know about
because of the buildfarm. I am happy to work on fixing it. No
discussion on responsibility there.

I can see that buildfarm animal is yours, so I asked you for more info
about the bug on that animal. ISTM reasonable to ask for some more
detail on a bug report, and where that is an automated service to
request that the owner of that service make changes to assist. I don't
see why that implies some change of my responsibilities.

Thanks for your help
