Description

The public reconstruction certificate has exactly the same content as the proof-side certificate, so the established crossing induction proves its encoded graph Welzl order.

Proof strategy

Convert each public twin expansion, checked reduction, and run to the corresponding proof-side certificate by induction on the constructors. The lists, sets, and checks agree directly; then apply the existing certified-run correctness theorem.

Attribution

This bridge carries the reconstruction correctness proof of Theorem 3.2 in Dreier and Kuske, Near-Linear Time Computation of Welzl Orders on Graphs with Linear Neighborhood Complexity, into the submitted certificate types.
