Redoing the `butler create` without `standalone` does result in a working repo. I've also fixed some other errors (apparently I hadn't run it on a machine other than rubin-dev: some of the repo files were `direct` transferred instead of `copy`). I'll post on middleware-support about what `standalone` is supposed to do.

Nima Sedaghat: the dataset repo should be working now. There are 4 PRs to review, and to process the data you'll need to checkout this ticket branch of ap_verify (as I noted above).

In that case, one more comment and I'll stop hijacking Nima Sedaghat's review: please update https://github.com/lsst-dm/jenkins-dm-jobs/blob/main/etc/scipipe/ap_verify.yaml to include the new dataset, per Ian Sullivan's 21 June comment.

I can confirm that the latest changes fixed the above error. ap_verify now runs with the accompanying dc2 CI dataset.

Getting back to code review.

On the pull request, there is a small comment from me, and one from Krzysztof Findeisen. I think after those are addressed, we can go ahead and close this ticket.

Assuming the docs and Jenkins CI (with the merged branches) runs tonight go through successfully, this should be ready to go!
