Checked statement containment

These exact targets occur inside this certificate. These links summarize containment, not direct dependency arrows; the downloadable bundle records every private lemma and ordered edge.

Scope

actual floor root lies between roots of supplied nonstrict lower and strict upper square bounds via replayed natural decidable order no real number or accuracy axiom

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