Time is routinely treated as a universal parameter applicable across all physical descriptions. This assumption is neither required by existing theory nor supported by physical practice, and it underlies the canonical problem of time in quantum gravity. As a follow-up to Event-Restricted Temporality and the Problem of Time, Event-Restricted Temporality (ERT) is developed into an event-licensed physics: temporal parametrization is a licensed operation whose domain is restricted to descriptions containing irreversible event actualization. Eight independent domain gates are introduced—quantitative, operational, control-theoretic, local, resource-theoretic, informational, thermodynamic, and phase-structural—that jointly constrain the physically admissible ways in which time may enter description. These domain gates convert temporal applicability from a tacit background assumption into a sharply posed physical question. The resulting framework preserves standard dynamics where events occur, explains the absence of time in purely structural and retentive regimes, and dissolves a broad class of temporal paradoxes without modifying quantum mechanics or general relativity.
