Why does quantum collapse only go one way in time?

Starting from the mathematics of random processes (Itô calculus), this framework derives why quantum wavefunction collapse is irreversible: running the equations backward in time is fundamentally incompatible with the stochastic structure, producing a universal asymmetry parameter of exactly 2/3. Applied to lithium-7 Bose-Einstein condensates, the model yields bright soliton solutions whose forward and backward collapse operators diverge by a factor of 10³⁰ — a number so large it effectively rules out any time-symmetric collapse description.
