Scope

independently supplied atanh prefix and longer table scales values and powers give valid rational monotonicity and uniform error three over three to cutoff without code equality or analytic limit

None of these finite arithmetic statements closes an IR campaign parent. The analytic identification, interpolation and final positive irrationality certificate remain open.
