Both claw-free Schur counterexample coefficients independently reproduced

Prior state unknownBoth published negative Schur coefficients independently reproduced exactly

An independent exact enumerator rebuilt both line graphs from the published edge lists and obtained the stated coefficients −64 and −40. VibeMathed's external label remains unreviewed; this is a separate local verification event.

Five-variable Hessian counterexample artifact replay passed

Prior state unknownExplicit construction artifact replay passed; symbolic determinant proof remains source-level

The pinned no-CAS checker reproduced the degree, monomial count, exact rational gradient collision, and deterministic exact Hessian evaluations. VibeMathed's external label remains unreviewed; this is a separate local replay record.
