$CD(2,\infty)$ conjecture for strongly regular graphs of girth three

Let $G=(V,E)$ be a strongly regular graph. Its girth is the length of its shortest cycle; in particular, girth $3$ means that $G$ contains a triangle. Strongly regular girth-three conjecture. Every strongly regular graph with girth $3$ satisfies $CD(2,\infty)$. The preceding curvature formulas establish the corresponding cases of girth four and five, but the asserted girth-three case is left as a belief in the source.
