GCFT-0422: Standard Model Parameter Closure Source Audit and Open-Gate Framework

A structured audit of the 2025 GCFT Standard Model reconstruction that separates ontology, parameter derivation, and publication readiness. Rather than presenting a completed derivation, the paper classifies unresolved parameter-closure problems—including the Higgs RG bridge, weak-angle evolution, lepton hierarchy, Yukawa replacement, and collider observables—into explicit open research gates. The work establishes a disciplined framework for future derivation packets while preserving historical continuity and preventing overstatement.
