Time as Cognitive Interface: A Structural Reconstruction of Dynamics Without Temporal Primitives

Time as Cognitive Interface presents a structural reconstruction of physical law without temporal primitives. The paper identifies time as an interface generated by cognitive architecture. The interface compresses structural change into a linear sequence that appears as temporal flow. The appearance is not a primitive feature of physical law. The analysis surveys the use of time in classical mechanics, electromagnetism, quantum mechanics, thermodynamics, and relativity. Each equation that uses time is rewritten in a time free structural form. The structure of each law remains intact. The predictions remain intact. The temporal variable is not required. The paper evaluates previous attempts to remove time from physics. These approaches remove time and then restore temporal structure through ordering, indexing, or gauge choice. These approaches preserve temporal ontology. Unified Primitive Theory provides a primitive architecture without temporal substrate. The primitive relation P(D_i, D_j) and the transformation T(D_i, D_j) generate dynamics through structural identity. The architecture relocates time from ontology to interface. The paper demonstrates that physics does not require time as a fundamental variable. The structural elimination of temporal primitives clarifies the foundations of physical law.
