I31B. Candidate Vitological Quantity and Unit: Metrological Specification, Practical Realization, and the Path toward International Recognition

I31B develops the documentary and metrological architecture required for the transition from a reproducible Vitological measurement residual to the question of an independent quantity and a candidate measurement unit. The article introduces a strict distinction among: Q_V — a Candidate Vitological Quantity; U_V — a Candidate Unit of that quantity; R_V — a practical realization of the unit; and T_V — a technical measurement system or process that may possess a separate legal and patent status. The central sequence of I31B is: Φ_M,R → candidate independent kind of quantity Q_V? → metrological specification → dimensional audit → unit U_V? → practical realization R_V → comparison and calibration → interlaboratory reproducibility → international metrological evaluation → only if sufficient evidence exists, a proposal for a special metrological status. I31B does not assume that E_VSA or η_VSA are already new measurement units. Instead, it introduces the neutral construct Q_V, which may arise only if reproducible measurement content remains after Scientific Subtraction, Functional Substitution, uncertainty analysis, and independent replication, and if that content requires a distinct kind of quantity. The article also separates metrological standardization from patent protection. A scientific theory, mathematical construct, or the idea of a new unit should not be confused with a patentable technical solution. Scientific and mathematical theories as abstract subject matter are distinct from specific technical implementations producing a practical technical effect.
