Do you mean actually build and run the kernel?
If so, it's not what I want to build into Sashiko directly, because
it will require significant infrastructure, a lot of hardware and
corresponding support and will complicate things a lot. However there
will be a database of pre-existing kernel bugs open to other trusted
tools (e.g. syzkaller) which will be able to enrich ai findings.

Sorry, not sure I got your idea. Can you elaborate please?

Thanks!
