Someone can point a gem with architectural failures?

[Gaius]

Hello guys

I'm searching for an Ruby's library that have architectural failures
related specifically to relations across modules.

Example: In a program written totally under MVC arquitecture, a
architectural failure occurs where the modules from the models access
objects from classes that belongs to the View or Controller modules.

So this I'm seeking: a library that have at least a module that should
not acess certain objects, but they do.

Very thanks for any help
