Speed as Structural Constraint (The Non-Modal Structural System V)

This paper fixes speed without introducing motion, rate, or propagation. Time has been fixed as retention without return under asymmetry, and a limit condition has been fixed under which retention holds as configuration, denoted as \( c \). Within this framework, speed is not derived from time, motion, or variation. Speed is not defined as the rate of change, nor as propagation across space. It does not measure variation and does not describe movement. Instead, it is fixed as a structural constraint under which retention holds as configuration. The bound \( c \) does not denote speed, magnitude, or any measurable quantity. It fixes the limit condition under which retention holds as configuration. The paper presents a non-modal structural system in which speed is neither motion nor rate but persists as a non-constitutive constraint intrinsic to retention under asymmetry.
