<p>Coulembier and Sherman ask whether six classical semisimplicity conditions are equivalent for a finite algebra object in a characteristic-zero supertannakian category. We give an affirmative answer. A minimal connected-invariant ideal is differentiably simple, so Kac's theorem identifies it with a simple associative superalgebra tensored with a Grassmann algebra. The Grassmann factor is its canonical supercenter. Coulembier--Sherman's commutative theorem makes that center absolutely flat, and separability of the simple factor transfers flatness to the full algebra. A separate internal <span class="math inline">\\(\\operatorname{Ext}^1\\)</span> argument closes the remaining implication.</p>
