Instead of treating diffusion, localization, and collapse of the wave packet as separate dynamical phenomena, we show that they originate from the symmetry structure of an underlying landscape in covariance space. The geometry of this landscape determines these distinct long time behaviors. Trapping potentials and bath fluctuations act as distinct symmetry-breaking perturbations, leading to noncommuting long-time limits and abrupt changes in the asymptotic wave-packet width. This geometric picture provides a unified origin for wave-packet diffusion, localization, and collapse in dissipative quantum dynamics.
