Lockfile CI documentation glosses over possible difficulties in atomic Artifactory copy of multiple packages

At the end of https://docs.conan.io/en/latest/versioning/lockfiles/ci.html it states:

> If the merge is a clean fast-forward, then the packages that were built in this job would be valid, and could be copied from the repository `conan-build` to the `conan-develop`.

How would such a 'copy' be accomplished for more than one package in an atomic way?

From what I understand from jFrog tech support, Artifactory's copy mechanism is not guaranteed to be atomic. Can you confirm?

Given that, how do you suggest we move packages from `conan-build` to `conan-develop` in a way that ensures developers don't accidentally grab an inconsistent view of the world?
