Too Long; Didn't Read
Eunice is designed to bring together the concepts of scope and isolation, through the wider concepts of structure and dependency. The scope of tests is an important part of code structure and complementary to how implementation is grouped. In React the most significant scope of structure seems to be the packages directory in the root of its repository. There were still some mismatching dependencies (red up arrows) at the packages scope. With tests ignored, the number of sub-directories with no bi-directional dependencies at the package scope has improved.
