@rwest I tacked on a85e44c to fix the Conda build check when running from forks.

The point of the conda_build change is so that the the workflow, on forks, does not fail (but it won't actually upload binaries), correct?
I can't tell that it'll work by reading the diff, but if it does what you intended, then this all looks fine to me.

[JacksonBurns]

Yeah it just runs the build but does not publish it

It looks like there's potentially something broken with this as CI is failing for new PRs:

Run actions/download-artifact@v4
Downloading single artifact
Error: Unable to download artifact(s): Artifact not found for name: stable_regression_results
        Please ensure that your artifact is not expired and the artifact was uploaded using a compatible version of toolkit/upload-artifact.
        For more information, visit the GitHub Artifacts FAQ: https://github.com/actions/toolkit/blob/main/packages/artifact/docs/faq.md

The name of the GitHub actions token was being passed incorrectly, I copied the fix in from the RMG-Py PR which fixed it.
