Summary: Certain separable, unital, amenable, non-simple \(C^*\)-algebras are classified by establishing that the essential structure of such algebras is encapsulated in the \(K_0\) group of the algebra along with the simplex of tracial states of the algebra cut down by projections
\[
A\cong B\Leftrightarrow \begin{cases} \varphi_0: K_0(A)@>\cong>> K_0(B)\\ T(eAe)@>\cong>> T(\varphi_0(e) B\varphi_0(e))\\ \forall e\in \text{proj}(A)\end{cases}.
