3105 — Circle Heat Preparation Cannot Collocate the Logarithmic Endpoint Port

The positive theta heat flow and the logarithmic tail live on different carriers. The circle Laplacian has discrete eigenvectors $e_n$ with eigenvalues $n^2$; logarithmic translation on $L^2(\mathbb R)$ has no nonzero eigenvectors.

Therefore every bounded operator intertwining those generators is zero. The circle seam delta cannot be transported into the logarithmic endpoint or theta source by a bounded carrier-preserving map.

The missing bridge must retain both carriers as a correspondence, including its adjoint boundary incidence. Heat-and-trace preparation is not a reversible port identification.

Scope

The bounded-intertwiner obstruction is exact. Rigged, unbounded, or two-carrier correspondences remain possible.
