Corollary. Transporting an artifact comparison [ftip-00G5]
If two artifacts \(M_1,M_0\) are scored by both \(s\) and \(t\) under the same law and \(\lVert s-t\rVert _{\infty ,\mathsf Q}\leq \varepsilon \), then the gain difference obeys \(|(J_s(M_1)-J_s(M_0))-(J_t(M_1)-J_t(M_0))| \leq 2\varepsilon \). This is a finite utility perturbation bound, not a training or distribution-shift theorem.
