WHY QUANTUM SYSTEMS ARE PHYSICALLY UNDER-SPECIFIED PRIOR TO IRREVERSIBLE ENFORCEMENT

This paper demonstrates, using physics-only logical necessity, that quantum systems do not possess physically definite states prior to irreversible interaction. It shows that quantum dynamics permit multiple transitions by default and that definiteness arises only when alternatives are physically excluded through dissipative coupling to inaccessible degrees of freedom. Under this framework, a “physical state” is not a mathematical description but an enforced restriction on allowed transitions. Definiteness is therefore not fundamental to quantum mechanics; it is a thermodynamic outcome of irreversible enforcement.
