The job is running here^

Ok, this is confusing. It is not present in https://osci-jenkins-1.ci.fedoraproject.org/job/fedora-ci/, and there there's the dist-git-pipeline which was recently updated to bump the timeout, and those also do koji builds?

I never used that job, no idea what is it for :)

Here is an example run for scratch-build-test. It was run on gdb@75e6fa, but it doesn't show up anywhere.

The test runs for certain components only and it shows up in Bodhi:
https://bodhi.fedoraproject.org/updates/FEDORA-2025-a3fba1c7cb

It's the "baseos-qe.koji-build.scratch-build.validation" result.

Ah, ok I see. Kinda weird to have scratch builds in the bodhi, but I guess it can catch some bootstrapping issues. I see there are 5 packages that gate it, all related to gcc.

It's basically a rebuild test -- "if I update gcc/..., will these other package still build successfully?"
