2623 — Two-Endpoint Nullity Does Not Imply a Bounded Reciprocal Lift

The forced source tail

$$G_s(q)=e^{-sq}\int_q^\infty f(v)e^{sv}\,dv$$

has both endpoint values zero when the scalar transform vanishes. Its complete reciprocal tail-seam energy nevertheless remains

$$E_\delta^{\mathrm{full}}(q) =2\cosh(2\delta q)\|f\|_2^2.$$

Therefore scalar nullity does not place the source state in the bounded reciprocal domain. Doing so by declaration would encode zero confinement in the domain choice.

The direct tail-equation route is closed. The surviving route must construct an independent boundary-bearing operator, derive its graph norm and kernel domain, and prove its determinant is the completed theta transform before the cosh obstruction can be applied.
