DefectBudget packages a positive real total_defect bounded by 1 as the normalized sum of J-costs over a configuration. Researchers on the Recognition Science zeta program would cite it when linking accumulated defect to a zero-free region sufficient for the RS chain. It is introduced directly as a structure definition whose three fields encode positivity and the unit normalization.

claimA DefectBudget is a real number $d$ satisfying $0 < d ≤ 1$, where $d$ is the total defect of a configuration.

background

The Weak Zero-Free Region module examines whether the defect-budget bridge can weaken or replace the full RH axiom. Total defect is the sum of individual J-costs (LawOfExistence.defect) over the entries of a configuration, and is non-negative by construction. The normalized sequence from RunningMaxNormalization supplies the unit bound used in the defect_bounded field. The module contrasts the classical Vinogradov-Korobov zero-free region with the weaker Hadamard-de la Vallée Poussin form σ > 1 - c/log(t) that the RS chain actually requires.

proof idea

The declaration is a structure definition that introduces the three fields total_defect, defect_positive, and defect_bounded with no proof steps or tactics.

why it matters in Recognition Science

DefectBudget is the input type for defect_implies_zero_free, which extracts the positive constant c = total_defect to produce the required zero-free region. It is also a field of RSChainRequirements and WeakZFRCert, closing the defect-to-zeta bridge that addresses the module's Q14 question. The structure therefore supplies the concrete hypothesis that may allow the RS chain to avoid assuming the full Riemann Hypothesis.
