Structural Principles of Stability, Pathology, and Collapse Canonical Principles of Viable Continuation Across Reflexive Systems

This paper presents a companion interpretive layer to the formal theorem framework developed in Viable Continuation Under Constraint. Its purpose is not to introduce new abstract machinery, but to extract a disciplined set of canonical principles from the proved continuation-boundary theory. These principles are intended to be portable across domains while remaining explicitly anchored to the underlying theorem spine. We distinguish three classes: cross-domain canonical principles, domain principles, and frontier principles. Cross-domain canonical principles compress the most reusable implications of the formal framework, such as the role of memory in diachronic correction, the danger of weak proxies, the fragility of correlated failure, and the pathological consequences of local success decoupled from whole-system viability. Domain principles specialize these insights to artificial intelligence, law, biology, civilization and markets, war and defense, political pluralism, ecology, and science. Frontier principles are included as explicitly programmatic compressions that extend beyond the closure of the current theorem package and point toward future work. The paper argues that such principles are neither slogans nor philosophical decorations: when correctly handled, they are compressed interpretive corollaries of a proved abstract framework. Their function is to provide a reusable conceptual vocabulary for understanding stability, pathology, and collapse across otherwise disparate systems. Trust boundary. Proved theorem statements and the Lean name map live in (-continuation-lean). The present text is interpretive: each principle is scoped in prose, and frontier-class items are explicitly not closed under the current package (see ; Lean bridge module Bridges. FrontierPrinciples where present in the artifact revision).
