Adaptive Constraint Structures in Physical Measurement

This work introduces adaptive constraint structures as an extension of constraint-based descriptions of physical systems. In this framework, constraint operators are allowed to depend on system state, time, and measurement history, providing a dynamic perspective beyond fixed operator formulations. Measurement processes are interpreted as sequences of adaptive constraint operations, suggesting that outcomes may depend not only on the system state but also on the structure of the measurement process itself. Possible realizations in systems with feedback, adaptive thresholds, and dynamically varying parameters are discussed at a conceptual level. This approach is intended as a structural extension consistent with standard quantum theory, rather than a replacement.
