Scope

construct positive fixed schedule half logarithm exponential tables after one chosen dyadic root and retain every actual factorial normalization and both checked cross errors

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