From Mapping Failure to Enforcing Impossibility: A Formal Distinction Between Descriptive State-Space Analysis and Constitutive Constraint Systems

This document serves as a conceptual supplement to Causal Sovereignty: Governing Irreversibility in Biological Systems. It clarifies the formal distinction between descriptive state-space analysis and constitutive constraint systems, with particular relevance to governance, safety, and irreversibility in complex systems. The work introduces no new empirical claims, methods, or implementations, and should be read as a boundary-clarifying conceptual note rather than a prescriptive or operational proposal.
