Scope

apply checked actual power cutoff budgets and positive cancellation to independent half logarithm exponential refinement without assuming the budgets changing the original logarithm computations or adding arithmetic helpers

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