The construction relies on the introduction of a new covariant derivative, which we name \"classical spin covariant derivative\", that is compatible with the three-point interaction of the $\\sqrt{\\mathrm{Kerr}}$ solution with the gauge field. The resulting Lagrangian, beside the correct three-point coupling, predicts a unique choice for contact terms and therefore it can be used to compute higher-point amplitudes such as the Compton, unaffected by spurious poles.
