Scope

construct unique actual floor root of twice any positive scale squared and prove it lies between the scale and twice scale with nonzero root no analytic interpretation

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