Scope

construct positive factorial weighted half argument exponential terms and both actual sums and bound the short sum square against the supplied whole argument sum without logarithm or square root identification

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