@stianst - happy to see the upgrade of the upload/download artifact. I tried some time ago and it was unstable then, see #25853

During another attempt in a personal repo, some weeks ago, I also saw problems similar as described in actions/upload-artifact#525.

Another thing: The flaky test handler seems to be depending on uploading artifacts the old way, please double-check on that as well. I didn't see any flaky test messages with the new ones.

Hmm... maybe it would be worth to split this up then, do the simple ones first, and do a follow-up with upload/download-action. Guess the best way to trial the flaky bot stuff is just introduce a flaky test that always fails the first time around.
