Dependencies

Use dependency rules when one component should or should not reference another component.

Allow Only These Components

controllers.can_use :models, :services

Rule id: dependencies.allow

can_use is an allowlist. References from controllers to any other declared component fail.

Forbid Specific Components

models.cannot_use :controllers

Rule id: dependencies.forbid

cannot_use is narrower. References to listed components fail; other declared dependencies are allowed unless another rule forbids them.

What Counts

ArchSpec checks visible dependency edges:

• constant references
• inheritance
• include
• prepend
• extend

It does not build a whole-program call graph.
