LGTM.

I'm wondering if we can set this up to trigger on dependency workflow/actions changing like we've done with other jobs to catch regressions earlier. It might need some restructuring though with the permissions check.

I'm also wondering if we're able to get rid of the cache filling stage now that double the cores are available on the free runners? Might reduce some complexity that isn't needed now.

Both of those are follow up patches though and can be addressed later.
