The exact quantum value of a cyclic Bell operator
A polar-decomposition certificate proves that the cyclic Bell operator of Perito et al. has value \(2\csc(\pi/(2d))\) for every \(d\ge2\), even in the commuting-operator model. Thus its finite-dimensional, approximate, and commuting values coincide.

A certified order-twelve extension of the γ–θ frontier
Combined with the published exhaustive result through order 11, a complete one-guard parameter split closes order 12 and places any counterexample at 13 or more vertices.

Eternal domination and the Lovász theta function
Published results combine to give an explicit family with \(\vartheta(G)/\gamma^\infty(G)=\Theta(|V(G)|^{1/3})\). Separately, the graph IEhbtj{ro is an exact minimum-order witness: \(\gamma^\infty(G)=3<7593/2500\leq\vartheta(G)\).

A 14-variable unipotent Keller map and unified obstructions
One formal-inverse mechanism joins an exact reduced three-point fiber, failure of SIC(14) at every exponent, and homogeneous Hessian-nilpotent Vanishing obstructions at every order in 30 variables at degree eight and 44 variables at degree four.

Full wreath-product monodromy through the third iterate
Provisional determinations of the degree-nine and degree-27 geometric monodromy groups as W2 and W3, with exact certificates. A separate, independently audited bounded-memory certificate proves the degree-81 group W4; none of these claims has external peer review.
