Scope

actual dyadic sqrt2 intervals at ordered precisions have valid rational nondecreasing lower and nonincreasing upper endpoints with proved denominator positivity no limit

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