This technical note introduces clockability as the minimal structural condition required for distinguishing temporal order. Rather than treating time as a primitive entity, clockability is defined in terms of trace persistence, accessibility, and comparability within physical systems. The note clarifies the operational threshold at which temporal description becomes applicable, without advancing new physical laws or ontological claims. It isolates a structural condition that is already implicit in experimental practice and measurement theory.
