The Boundary Coherence Model: A Constraint-Driven Methodological Framework for the Measurement of Institutional Coherence.

The Boundary Coherence Model (BCM) is an original, constraint-driven methodological framework designed for the quantitative measurement of institutional health. This Master Declaration comprises the foundational 460-page corpus—encompassing specification, instrumentation, and execution—finalized for external review and replication. The BCM posits that institutional failure is not merely a matter of material success or failure, but a collapse of "Coherence": the coupling between an institution’s operative definitions (what it claims to be) and its material outcomes (what it actually does). By formalizing "Definitional Drift" (D(t) \equiv -dC(t)/dt) as a measurable signal, the framework provides a diagnostic apparatus to identify institutional decay before total systemic dissolution occurs. Key Components of the Deposit • The 27-Attribute Measurement Matrix: A granular diagnostic tool for assessing institutional state-space. • Hierarchical Bayesian Measurement Model (HBMM): The statistical backbone used to aggregate attribute codings into a single Coherence Index Score (CIS). • The Calibration Corpus: Includes four "Closed Window" civilizational audits (Rome, Venice, Ottoman, British) and two "Live Audit" negative controls (USA and Germany). • The Boeing Audit (1997–2026): A primary proof-of-concept applied to modern corporate governance, diagnosing the structural transition from engineering primacy to extraction-oriented architecture. • Adversarial Coding Manual: A discipline for inter-rater reliability (IRR) designed to minimize analyst bias during the coding process. Stage 0 Status & Invitation to Replication This deposit represents "Stage 0: Signal Tier." The findings contained herein are binding as pre-registered hypotheses. The work is now finalized for Stage 1: External Replication. Scholars and practitioners in institutional economics, political science, and systems engineering are invited to engage with the evidence packets and coding manuals provided to test the framework’s discriminant validity. "The audit is the defense. The boundary is the law."
