Operando spectroscopy reveals electrode\u2010dependent modulation of the Co valence, while complementary structural and vibrational measurements show no macroscopic lattice change but clear local rearrangements of the oxygen coordination, indicating an interface\u2010controlled, spatially distributed redox mechanism. These results identify electrode oxygen\u2010exchange capability as an important parameter governing switching polarity and redox dynamics in topotactic transition\u2010metal oxides. The combined electrical and spectroscopic observations further support the contribution of a distributed redox mechanism to the switching process.\n
