Description This work addresses the following foundational question: What necessarily follows if a law of conservation is assumed in the structural sense of Noether, prior to any notion of time, evolution, or dynamics? Assuming conservation as a primitive requirement, the analysis examines the minimal conditions under which invariants associated with a conserved Noetherian flow remain identifiable when access to the underlying degrees of freedom is intrinsically restricted. It is shown that conservation alone is insufficient to define a consistent description unless an ordering relation exists. Such an ordering is not postulated, but is enforced by the requirement that invariants remain distinguishable under irreversible loss of accessibility. The central result is that an ordering relation necessarily emerges once conservation is imposed under restricted accessibility. This ordering cannot be reduced to a coordinate, parameter, or dynamical variable; it functions instead as a structural ordering constraint required to preserve invariance under non-invertible projection. No spacetime geometry, equations of motion, or phenomenological dynamics are assumed. All results follow from consistency requirements on conservation and observability. Temporal structure is therefore identified with an ordering relation enforced by structural constraints, rather than with a fundamental element of the theory. This manuscript is a preprint presenting a foundational derivation.It has not undergone peer review and may be revised.
