Hi, I don't seem to be able to see the ERT explainer output in the logs added in https://debbugs.gnu.org/cgi/bugreport.cgi?bug=73441 for proced-refine-test.

Has that patch been applied here or am I missing it?  If not it would possibly explain the flakiness fixed by that patch too.

Otherwise I can't reproduce the test failing with no ERT explainer output copying the flags in the logs (my hope would be the ERT explainer output would show the underlying cause as before).

Thanks, Laurence

Laurence, could you please look into fixing this?
