UFPC: Unified Feasibility Persistence Canon

The Unified Feasibility–Persistence Canon (UFPC) is a closed, axiomatic framework defining existence, agency, feasibility, collapse, and structural ethical obligation in constrained, irreversible systems. The Canon formalizes a single invariant:systems that eliminate their own feasible future transitions lose the capacity to persist. Rather than prescribing goals, values, or policies, the UFPC provides a measure-theoretic ontology of realized states, a cost-based model of irreversible transitions, a local execution framework for agents under constraint, and a global criterion for persistence and collapse. Ethical obligations are derived structurally from shared feasibility constraints, without the introduction of normative values or preferences. All primitives are explicitly defined. All limits are stated. Computability boundaries are made explicit. The framework is scale-invariant, domain-agnostic, and resistant to goal injection, observer privilege, and infinite-budget assumptions. This release corresponds to Version 1.0 (Diamond Closure). The document is canonically locked and self-contained. No revisions, extensions, or reinterpretations are permitted under this version identifier. The UFPC is intended as a formal reference framework suitable for analysis, critique, or instantiation across domains including dynamical systems theory, governance modeling, ecological collapse analysis, and agent-based systems. It does not constitute policy advice, moral prescription, or ideological position.
