Institutional Legibility Architecture (ILA): Doctrinal Framework, Public Audit Protocol (ILA–PLAP v1.0), and Applied Case Studies

Abstract The Institutional Legibility Architecture (ILA) is a domain-agnostic structural framework for evaluating the coherence, traceability, and correction capacity of organized human systems. The architecture defines seven invariant layers required for institutional intelligibility: Boundary Definition, Actor Topology, Decision Surface, Trace Layer, Feedback Channel, Drift Detection, and Correction Mechanism. This deposit contains three coordinated components: A doctrinal formulation defining the seven invariant layers and their associated failure taxonomy. The ILA Public Legibility Audit Protocol (ILA–PLAP v1.0), a replicable, artifact-driven procedural instrument for assessing institutional legibility without reliance on predictive modeling. Applied case studies demonstrating cross-domain implementation through structured analyses of the 2008 Global Financial Crisis and the Flint Water Crisis. ILA does not prescribe policy outcomes or normative positions. It defines structural conditions under which institutions remain reconstructable, accountable, and procedurally self-correcting. The framework is intended for governance analysis, institutional auditing, civic oversight, and organizational design evaluation. Description This deposit presents the Institutional Legibility Architecture (ILA) as a unified structural framework for governance and systems diagnostics. ILA defines seven invariant layers required for institutional intelligibility. The layers remain structurally constant across domains; only parameters and contextual inputs vary. The seven invariant layers are: Boundary Definition Actor Topology Decision Surface Trace Layer Feedback Channel Drift Detection Correction Mechanism Each layer includes: Formal definition Structural requirements Failure mode classification Legibility standard The deposit contains three coordinated documents: Institutional Legibility Architecture (ILA) — Doctrinal Formulation v1.0Formal architectural statement of the seven invariant layers, consolidated failure taxonomy, and constitutional charter. ILA–PLAP v1.0 — Public Legibility Audit ProtocolOperational instrument enabling replicable institutional assessment through artifact indexing, anchored scoring, inter-rater documentation, and documented correction pathways. The protocol operationalizes ILA without modifying its invariant layers. Institutional Legibility Architecture (ILA) — Applied Case StudiesLayer-structured analyses of: The 2008 Global Financial Crisis The Flint Water Crisis The case studies demonstrate cross-domain application of the framework while preserving structural invariance. The architecture is designed for: Governance analysis Institutional auditing Public accountability review Civic transparency initiatives Organizational design evaluation Systems stability assessment ILA does not replace regulatory authority, judicial review, or policy deliberation. It provides a structural diagnostic lens for evaluating institutional legibility conditions. Version 1.0 establishes the foundational doctrinal and procedural baseline.
