Black Holes as Saturation Endpoints of Irreversible Constraint Accumulation

This paper presents a regime-based account of black holes as saturation endpoints of irreversible constraint accumulation within a variational dissipative–conservative framework. Following the emergence of discrete events, stabilised classical transport, and effective geometric description, increasing constraint progressively restricts admissible transport paths until persistent continuation becomes globally obstructed. Black holes correspond to regimes in which transport admissibility collapses beyond a critical threshold, giving rise to effective horizons, irreversible exclusion, and the breakdown of geometric encoding. Event horizons are interpreted as transport-admissibility boundaries rather than fundamental causal barriers, while singularities mark the limits of geometric description rather than physical infinities. No modification of general relativity, quantum mechanics, or black-hole thermodynamics is proposed. The contribution is explanatory and foundational, clarifying why black-hole structure and horizon behaviour arise inevitably once geometry emerges from irreversible transport.
