This paper introduces proto-agency as a limited physical concept within USP Field Theory. The term does not refer to consciousness, intention, choice, or free will. Instead, proto-agency is defined as the ability of a non-living molecular system to convert environmental disturbance into an internally biased, repeatable, direction-selective response. The document proposes a mechanism sequence: disturbance → damping → beat-mode formation → delay asymmetry → directed response The central example is a metastable cluster in a warm liquid or soft reconfigurable medium that suddenly experiences cooling, drying, chemical change, boundary contact, light input, or another environmental shift. As the system retunes, incompatible oscillatory modes decay, while compatible modes may partially lock and form a slower beat mode. This beat mode can couple fast microscopic oscillations to larger collective degrees of freedom, such as boundary relaxation, droplet deformation, capillary motion, gel reshaping, vesicle breathing, or weak hydrodynamic flow. The key step is delay asymmetry. If one side of the cluster cools, dries, relaxes, or contacts a surface faster than another side, the collective beat unfolds unevenly. This produces a spatial bias in the system’s response. The system is still non-living, but it is no longer purely passive: its internal state affects how it responds to the next perturbation. This paper is positioned as a bridge between earlier USP documents on molecular resonance boundaries, states of matter, coherent locking, and temperature-as-resonance disturbance, and later USP documents on life, memory, and biological damping. It explains how a reconfigurable molecular system could cross from passive metastable chemistry toward primitive active maintenance. Lightning is discussed only as a secondary example of a high-energy perturbation. The main mechanism is low-energy and biologically relevant: warm–cold cycling, wet–dry cycling, hydration gradients, chemical gradients, boundary contact, and relaxation-delay asymmetry. These are more plausible and repeatable than rare catastrophic events. The document includes operational proxies, a droplet-cooling pilot test, hydrodynamic controls, a non-circular calibration protocol, and a methods appendix. It also includes falsification criteria requiring that any observed directionality be separated from ordinary causes such as Marangoni flow, convection, evaporation, contact-line pinning, external vibration, and asymmetric illumination.
