3800 — A Two-Atom Source Falsifies Universal Null-Implies-Exchange-Intertwining

The positive reciprocally even source

$$F(z)=3\cosh z+\cosh 2z$$

has an exact off-seam zero. Setting $y=\cosh z$ gives

$$2y^2+3y-1=0,$$

whose negative root yields

$$z=\operatorname{arcosh} \left(\frac{3+\sqrt{17}}4\right)+i\pi.$$

At its positive real displacement $a$, the exchange energy is

$$8\left(3\sinh^2a+\sinh^2(2a)\right)>0.$$

Thus scalar nullity does not imply exchange intertwining for positive reciprocally even sources. The missing action law must explicitly consume a theta-specific capability. The surviving conditional target includes zero residual against the canonical moving-incidence connection; both this two-atom source and the denominator-three hostile fail that antecedent.
