What FID Hides: Detecting, Ranking, and Diagnosing Deviations in Generative Evaluation

ZID is introduced, which combines six standardized location- and dispersion-sensitive arms from a rank graph and Gaussian kernels (GPK at two bandwidths) and reports three linked outputs: an index for ranking departure magnitude, a permutation-value for testing distributional equality, and a signed dispersion readout for diagnosis.
