How is sashiko bot deciding whom to Cc?

There doesn't seem to be a Sashiko list, so I added ksummit as the most
likely one to catch attention. 

If you run b4 mbox  20260905153514.B55561F00A3A@smtp.kernel.org 
you will observe:

So it picked some mailing lists but not others, and some specific people.

Is that opt-in somehow? I'll be happy to get Cc'd on the auto-review email.
