Abstract
Across physical, biological, and Socio-technical domains, many long-lived systems operate neither near thermodynamic equilibrium nor as short-lived non-equilibrium transients. Instead, they persist as nonequilibrium steady states sustained by irreversible processes, continuous throughput, and finite structural carrying capacity. Despite this, prevailing analytical and design frameworks often rely on equilibrium references, point-valued state descriptions, or optimality-based objectives. While effective for short-term or approximately closed systems, these approaches become systematically mismatched for systems operating over extended durations under irreversible dissipation, where statistical stationarity may coexist with structural degradation. We adopt the premise that observation is inherently embedded within the system and remains valid only relative to explicitly declared observational frames and temporal scales. Under unavoidable partial observability, non-equilibrium existence is diagnosed not by trends or performance metrics, but by the persistence of irreversible directional structures that survive statistical stabilization and are invalidated under time reversal. We introduce a structural diagnostic framework based on (i) observation–structure mismatch, (ii) inner–outer cycle coupling admitting discrete regimes, and (iii) pathology localization at high-coupling nodes. When driving fields are not directly measurable, an inverse-measurement perspective is employed, treating structural stress responses as probes of system-wide pressures. Within this framework, resilience is redefined as the preservation of reversible coupling intervals, and design is repositioned as a bounded structural modulator rather than an optimization mechanism.
