However, I'd like to hear from@QuLogic as to whether the lack of checkout is intentional or not.

🤦‍♀️ knew I saw that somewhere

And for checkout, maybe has to do w/https://github.com/actions/labeler#notes-regarding-pull_request_target-event

I think you were looking at old docs (and the referenced issue is older than v5); the v5 ones don't mention needing a checkout. In fact, the docs say it will read from the source repo (which it has been doing all this time). And I don't think it would have any effect, aspull_request_target will clone from the main repo, not the fork. That does unfortunately lead to the "can't test beforehand" issue.

So the changes to the workflow appear superfluous, as they are just setting configuration to the defaults and adding a checkout that doesn't do anything.

. In fact, the docs say it will read from the source repo (which it has been doing all this time).

I was just confused why it was still getting that error message, but just undid those changes.
