The Constrainton A Conditional Geometric Field Excitation Mediating Non-Adiabatic Boundary Updates

The Constrainton is a conditional theoretical framework proposing that changes in physical boundary conditions—when treated as real, time-dependent processes rather than abstract inputs—must propagate causally and locally. The theory introduces a minimal scalar field excitation that is sourced only during non-adiabatic boundary motion and mediates the update of admissible mode structure (“rules”) rather than field amplitudes (“values”). This excitation carries energy supplied by mechanical work on the boundary and produces a measurable back-reaction interpreted as geometric damping. By distinguishing rule propagation from standard value propagation in quantum field theory, the framework provides a conservative extension of existing physics without modifying established equations, while yielding a falsifiable prediction of geometry-correlated impulses or damping effects at high boundary actuation frequencies.
