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

compare actual supplied horner histories by explicit pairwise induction to prove long value equals base times odd slice value at squared base with every even coefficient zero including the terminal entry

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