VMAF Methodological Protocol and Reproducibility Note for The Voynich Manuscript as a Structural Loop System

This methodological note is a reproducibility supplement to the DOI-registered paper The Voynich Manuscript as a Structural Loop System. It clarifies the operational protocol behind the VMAF structure-first analysis of the Voynich Manuscript, including GPT-assisted Builder / Evaluator / Supervisor role separation, EVA-based textual testing, Yale/Beinecke visual-only analysis, held-out validation, frozen outputs, reduction testing, failure conditions, and requirements for independent criticism or replication. The note does not propose a decipherment, translation, plaintext recovery, cipher key, hidden language, historical attribution, or final solution to the Voynich Manuscript. Its purpose is to make the VMAF experimental process more inspectable, criticizable, and potentially reproducible before semantic interpretation is attempted.
