Theorem 3: Recursive Governance Continuity Theorem in Self-Preserving Flow (SPF)

This theorem extends the SPF hierarchy from state continuity (Theorem 1) and constraint continuity (Theorem 2) to recursive governance continuity. We prove that longhorizon intelligent stability requires not only recoverable state evolution and recoverable constraint evolution, but also recoverable evolution of the governance operators that regulate semantic revision itself. The theorem introduces a third-order governance operator Ψt : Φt → Φt+1 which governs the admissible transformation of Meta-SCL revision dynamics. Without a recoverable governance lineage, recursive semantic systems inevitably enter governance drift, resulting in the irreversible collapse of historical interpretability across infinite meta-regression.
