Structural Tiers, Dark Base, and Phantom Pillars - A Physics-Based Framework for Sustainable Accumulation and Hybrid Collapse in Complex Systems

This paper presents a non-ideological, constraint-based framework for growth, inequality, and collapse in complex systems by modeling accumulation as a height field supported by a finite, partially observable base. Height represents accumulated capability (wealth, leverage, organizational capacity, complexity) while base represents load-bearing support (buffers, redundancy, institutional capacity). Core Framework & Contributions: False Stability: A regime where sustained surface growth coexists with the hidden depletion of support in lossy systems. Hybrid Collapse: A failure mode characterized by slow, invisible erosion punctuated by sudden, rapid avalanches. Structural Tiers: Discrete upgrades that do not add height directly but alter the geometry of the system (reducing marginal cost or raising stability thresholds). Dark Base & Phantom Pillars: We introduce the concept of "Dark Base"—support that is structurally real but epistemically inaccessible during operation. This support forms "Phantom Pillars" that rely on belief; when belief drops below a threshold, these pillars fail discontinuously, creating an Epistemic Cliff where the system transitions from apparently robust to catastrophically under-supported without warning. Methodology & Applications: The framework provides a closed formal scaffold, diagnostic observables (including a Phantom Dependence Index), and schematic simulations. It is applied to three worked case mappings to demonstrate domain-agnostic utility: The 2008 Financial Crisis (Phantom pillars in liquidity/collateral). The 2003 Northeast Blackout (Dark base in operator coordination). The Challenger Disaster (Erosion of informal veto power). This work is intended as a structural language for safety engineering, econophysics, and systemic risk analysis, applicable wherever accumulation occurs under finite, lossy, and partially observable support.
