Calculation record

Radial endpoint kernels and the full angular tunneling chain.

The leading normal operator is D_geo - g C(chi_- h+chi_+ hbar).
The angular link is used only to derive a bounded Hermitian completion.
The completed operator has the original principal symbol. Its leading
endpoint coefficient is computed without projecting out the radial fields.
The physical same-field origin and finite-normal-scale corrections remain
separate questions.
