    Shopify's engineering blog introduced Packwerk as a static-analysis gem that enforces package boundaries inside its Rails monolith. Its README states that Packwerk only cares about static constant references and that method calls and objects passed around the application are completely ignored. What does that design buy a platform team that wants to run the check as a blocking gate, and where would copying it be a mistake?
