today's EP-violation signal = 0 exactly,

Compute the Nordtvedt equivalence-principle parameter $\eta = 4(\beta_{\mathrm{PPN}}-1)-(\gamma_{\mathrm{PPN}}-1)$ for SVT and compare to the LLR bound $\eta=(-0.8\pm 1.3)\times 10^{-4}$ and the next-generation APOLLO/ELRAD target $|\eta|\le 3\times 10^{-5}$.

In the IR-protected regime (sim_46) SVT sits at $\gamma=\beta=1$ exactly, so $\eta_{\mathrm{SVT}}(z{=}0)=0$ — trivially below every existing and forecasted LLR bound. Unlike chameleon models that predict $\eta>0$ via scalar coupling to nuclear binding energy, SVT's null is a structural prediction of the IR fixed point. The non-trivial content is the drift: $\mathrm{d}\eta/\mathrm{d}z$ turns on immediately above $z_{\mathrm{IR}}$, so APOLLO / ELRAD can either see the drift (detection) or tighten the bound on $z_{\mathrm{IR}}$ (constraint).

LLR has been the tightest gravity test for 55 years and has ruled out most scalar-tensor Nordtvedt signals. SVT's temporal screening makes it maximally consistent with LLR *today* while leaving a detection channel open in next-generation retroreflector experiments — the postdiction-then-prediction pattern Dr. Turyshev's paper specifically asks for.
