[candera]

Background

Slingshot is an enhanced throw/catch framework for Clojure. It may have advantages over artifact.error. We should check it out to see if it provides any benefit.

Acceptance Criteria

• A recommendation is documented here on whether or not to convert to using slingshot
• If conversion is recommended, new issues are created to convert the code to using slingshot
