Finite-Distinguishability Closure and a Distinguished Dimensionless Residue (v2)

This record corresponds to Version 2 (v2) of the Finite-Distinguishability Closure (FDC) framework. The present upload provides a complete structural specification of the framework,including: - Tier 1–4 axiomatic and structural layers,- Route I closure construction,- Route II structural outputs,- explicit closure formula,- and a fully reproducible numerical evaluation layer. All results are internally defined and do not rely on empirical fittingor externally imposed physical constants. This version extends the previously released FDC-V1 by addinga consistent numerical realization corresponding to the structural closure. All components required for independent reconstruction are includedin the attached files.
