  "abstract": "We compute the four-loop matching of a CP-odd four-$τ$ interaction onto the electron electric dipole moment (EDM), together with the leading timelike $τ$ dipole form factor generated by the same source. Both results are scale independent at this order. Without a local electron dipole, exact electron-EDM cancellation still leaves a timelike $τ$ signal proportional to the four-$τ$ coefficient. Its absorptive part cannot be canceled by a real local dipole, allowing collider limits to constrain the cancellation direction and complement static electron-EDM searches.",
