Recorded by the registry's curators from GitHub; the authors did not submit it here.

OpenAI Codex agents (AI-generated formalization)

Proof of the full original target, using Prony reconstruction and a Koszul determinant certificate; draft pending authoritative Linux verification and final independent review.
