This release (v27.4 – Round 5 Complete) presents the latest consolidated version of the formal verification framework for the Yang–Mills Mass Gap problem, integrating the Consensus Framework, Lean 4 formalization, and Lattice QCD numerical validation. The methodology bridges formal mathematics, distributed AI reasoning, and physics-based simulation, establishing a reproducible, transparent, and verifiable foundation for multi-agent scientific collaboration on one of the Clay Millennium Prize Problems. Recognition and Context The Consensus Framework, which defines the methodological core of this work, was awarded the 2025 UN Tourism IA Global Challenge Champion title, after competing with 440 solutions from 83 countries. https://www.untourism.int/news/un-tourism-sets-artificial-intelligence-agenda-for-sector-as-general-assembly-concludes-in-riyadh The framework was recognized for its innovative approach to multi-agent alignment, explainable reasoning, and transparent consensus protocols — demonstrating how AI collaboration can address complex scientific and societal problems.
