I wanted to let you know that I linted all conda-recipes in your PR (recipes/pattern-causality/meta.yaml) and found some lint.

Here's what I've got...

For recipes/pattern-causality/meta.yaml:

• ❌ There are too few lines. There should be one empty line at the end of the file.
• ❌ The extra section contained an unexpected subsection name. maintainers is not a valid subsection name.
• ❌ The extra section contained an unexpected subsection name. authors is not a valid subsection name.
• ❌ Non noarch packages should have python requirement without any version constraints.
• ❌ Non noarch packages should have python requirement without any version constraints.
