= ADM boundary term of the Nester two-form

For asymptotically constant spinors, the leading intrinsic <spin connection> term gives half the ADM metric integrand times $K^0_\infty$. The <Sen spinor connection> correction gives $-(k_{ij}-kh_{ij})K^j_\infty$. The constant-spinor derivative term integrates to zero by antisymmetry of the gamma matrices, and the remaining quadratic terms vanish under the standard decay. This identifies the <Nester two-form> flux with the ADM energy-momentum contraction, including momentum rather than just energy.
