Actual support conditions for the pole expansion
Geometric support in a radius-1/4 cap implies all support conditions in the quadratic stationary theorem. The ambient pole bump is invisible to the actual coefficient jets at its center.

The incoming pole uses the same smooth direction patch as the outgoing pole, applied to the conjugated antipodal amplitude.

OAI.Falconer.poleLocalized_stationary_remainderline 179Source documentation
The local expansion has the original-amplitude coefficients. All support and smoothness requirements are discharged by the fixed bump. The remaining derivative bound is the explicit Euclidean jet budget.
