GRADE's gradient-subspace stable rank is a normalized covariance-spectrum construction with no established formal reduction to the Fisher information matrix

Gradient 'geometry' is one shared object — the Fisher/K-FAC matrix — across GIFT and Amari, but a formally distinct construction in GRADE: not one object across all three, nor three unrelated analogies

Capture: Is 'gradient geometry' one shared mathematical object across GIFT's isotropy transform, Amari's natural gradient, and GRADE's subspace rank — or three superficial analogies?
