Scope

construct at every precision the actual half log exponential and same denominator dyadic floor root preserving all computations and square bounds and proving both finite cross product errors without an infinite identity

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