What you'd want is Architecture Unit Tests; you can define in code the metastructures and relationships, and then cause the build to fail if the relationship is violated.

The classic is ArchUnit in Java:

    @ArchTest
    static final ArchRule  layer_dependencies_are_respected = layeredArchitecture().consideringAllDependencies()

            .layer("Controllers").definedBy("com.tngtech.archunit.example.layers.controller..")
            .layer("Services").definedBy("com.tngtech.archunit.example.layers.service..")
            .layer("Persistence").definedBy("com.tngtech.archunit.example.layers.persistence..")

            .whereLayer("Controllers").mayNotBeAccessedByAnyLayer()
            .whereLayer("Services").mayOnlyBeAccessedByLayers("Controllers")
            .whereLayer("Persistence").mayOnlyBeAccessedByLayers("Services");

The problem I've had with these tests is that the run time is abysmal, meaning they only really get run as part of CI and devs complain that they fail too late in the process

Also, I'm on mobile so apologies for the badly formatted code - original can be found here: https://github.com/TNG/ArchUnit-Examples/blob/main/example-j...
