Rotation Logic
Eligibility, Duration, and Rotation
Rotation Logic is the structural vocabulary used to analyze how eligibility rules determine authorization to hold office across time.
Rotation is not a descriptive pattern or electoral outcome. It is a structural result produced when eligibility to hold office is exhausted and cannot be restored. Systems that allow eligibility to reset, regenerate, or transfer preserve authorization and therefore do not produce rotation, regardless of how frequently incumbents change.
Within the Framework, Structural Validity defines how eligibility rules are specified and applied, while Normative Adequacy is reflected in resulting patterns of tenure, continuity, and rotation. This vocabulary distinguishes between eligibility exhaustion and permission-preserving regimes, clarifies the difference between eligibility and ballot access, and identifies the structural mechanisms through which authorization is either terminated or maintained.
Rotation Logic provides the controlled analytical vocabulary used to classify institutional designs and eligibility architectures across the Framework, Worked Examples, and the Case Library. It defines how eligibility to hold office is accumulated, exhausted, or restored, and how those conditions determine whether rotation occurs.
In practical terms, Rotation Logic shows how different eligibility rules produce different patterns of stability, succession, and institutional behavior.
Rotation Logic does not evaluate desirability, legitimacy, or effectiveness; evaluation occurs only when these classifications are applied within the Framework.
Context + System Placement
Foundational definitions used throughout the Framework are centralized on the Core Concepts of Rotation Design page, which introduces the core vocabulary used across Rotation Logic and the analytical modules.
The historical development of rotation in office across republican systems is summarized in A Brief History of Rotation.
Conceptual Model
Rotation Logic assumes a historical model of distributed constitutional self-correction in which stabilizing mechanisms—such as rotation produced by duration-vector eligibility exhaustion—operate through political practice across time. It distinguishes this model from contemporary pre-enforcement supremacy, which frequently shapes modern institutional response patterns.
Navigation / Function
The pages linked below classify institutional architectures, operating conditions, emergent dynamics, failure modes, and response patterns descriptively prior to evaluation. Together they provide the analytical vocabulary required for consistent structural analysis across the Framework, Worked Examples, and the Case Library. These classifications also clarify how system-level adjustment occurs across layers through self-correction within institutional systems over time.
The structural layers below summarize the analytical progression used throughout Rotation Logic, beginning with the Governance Legitimacy Field within which institutional architectures and system behaviors operate.

The Framework uses this vocabulary to assess Structural Validity (Module I) and Normative Adequacy (Module II).
Worked Examples demonstrate classification and analysis step-by-step.
The Case Library applies the same logic across jurisdictions and institutional designs.
Core Concepts
Defines the foundational vocabulary used throughout the Rotation Research Framework, including rotation, durability, voluntary departure, and the structural distinction between authority and power.
Governance Legitimacy Field
Describes the legitimacy field within which governance systems evolve and within which the institutional architectures and system behaviors classified in Rotation Logic operate.

Analytical Discipline
Readers are encouraged to begin with architectural classification before applying evaluative tools. Within System Behavior, readers may begin with Constraints on Power, which provides the structural progression linking emergent dynamics, institutional responses, and failure modes.
