DESCRIPTION:This work completes the arrow of time problem by supplying the mechanism physics lacks. Microscopic laws are reversible, yet macroscopic processes exhibit irreversible entropy increase. Standard thermodynamics describes entropy but does not explain how temporal asymmetry emerges from symmetric laws. Using the Carlo Framework, this paper introduces the contradiction engine, the trajectory update rule, and the Reset Operator > as the missing structural components that mechanise irreversibility. The completed model treats the conflict between reversible microdynamics and irreversible macrodynamics as a contradiction loop. When this loop exceeds tolerance, the Carlo reset mechanism produces entropy increase and temporal direction. This paper formalises the temporal contradiction, defines the reset threshold, and provides a unified mechanism linking microscopic symmetry to macroscopic asymmetry.
