Scope

construct actual powers heads shifted slices and sums with dyadic decay after every extra cutoff beyond twice a general natural argument bound including all zero margins and without an infinite remainder claim

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