CDN-229 converts the CDN-228 fixed SPARC rotation response into a lensing-parity contract. On the held-out half, the spherical-equivalent response implies median required lensing mass boost Mdyn/Mbar = 2. 650 and median response fraction MXi/Mdyn = 0. 623. The result is not an observed lensing pass; it locks the required prediction that the response contribution must lens through the same potential that supplies the extra circular-speed support.
