Using the Block Pattern in a Business Unit?

We went through the journey of state management, from lim what you would do ithjust calling said state, and up to using a the block design patten with we kind of state. And basically we said, k during the consultancy, if anything out of the architectural bits are not e fine tunes yet, well, we can refine them during that period. So i don't think we be allowed, i any any place in the ap, for one block to communicate with the other. Once a us case communicates with another one or calls into it, basically that's a disaster waiting to happen.
