A Temporal-Orientation Framework for Wavefunction Collapse

This work proposes a framework for wavefunction collapse based on temporal-orientation dynamics in an extended Hilbert-space structure. The model introduces asymmetric temporal sectors associated with observer-system interaction and derives irreversible collapse behavior through GKSL-consistent dynamics, stochastic unraveling, and observer-alignment mechanisms. The framework recovers Born-rule statistics while remaining operationally compatible with standard quantum mechanics in the appropriate limits. The paper distinguishes explicitly between formal theorems, operational propositions, and heuristic interpretations, and proposes numerical simulation protocols intended to assess empirical distinguishability relative to standard quantum theory. This preprint represents Phase II of a broader research program concerning temporal structure, quantum measurement, and relativistic extensions of collapse dynamics.
