r_joint = max(|τ|,15/17), with rate-resonance surface |τ|=15/17.
For (a,b,κ)=(4,9,0.5), τ=0.509893953950370 while 15/17=0.882352941176471. The E47 complement is therefore the asymptotic bottleneck for this witness.

The finite-dimensional simulation validates the CPTP block-dephasing channel D_P(ρ)=PρP+QρQ. It is not a quantum-hardware execution and does not assert that the nonlinear Newton map is a physical quantum channel.
