And the CI test failure is this, the reporting is not great because we run check- targets one after another. This test was already failing on main.

If it fails again download the logs and search for "Failed<2-3 spaces>" and you'll see any results summaries where something failed. I plan to work on combining the results so this isn't a problem in the future.
