In this setting, the classical singularities are replaced by quantum-induced shell-crossing singularities, which are resolved through weak solutions such as shock waves. By formulating the dynamics in a generalized Painlev\\'e--Gullstrand coordinate system, we derive a first-order partial differential equation that governs the propagation of the shock surface, while enforcing metric continuity via thin-shell junction conditions.
