SΔϕ-30 AI-READABLE Package — Diagnosing Closed Defaults (v1.0)

<p> This record provides the AI-readable structured package for <em>SΔϕ-30 — Diagnosing Closed Defaults: Minimal Tests for Editable Governance after SΔϕ-29 (v1.0)</em>. </p> <p> SΔϕ-30 extends SΔϕ-29 by distinguishing formally declared editability from operationally real editability. Many systems present themselves as revisable, participatory, open, consultative, or appealable while functioning in practice as closed-default regimes. The central claim is that <strong>editability claimed is not editability real</strong>. </p> <p> SΔϕ-30 proposes four minimal diagnostic tests for editable governance: <strong>Revision Reality Test</strong>, <strong>Rollback Reality Test</strong>, <strong>Exception Re-entry Test</strong>, and <strong>Authority Distribution Test</strong>. In formal terms, <code>D* editable-real iff Rv ∧ Rb ∧ Ex ∧ Ad</code>, where <code>D*</code> is the current default path, <code>Rv</code> is exercised revision, <code>Rb</code> is timely rollback, <code>Ex</code> is material exception re-entry, and <code>Ad</code> is materially distributed authority. </p> <p> The Revision Reality Test asks whether the default is actually revised or merely declared revisable. The Rollback Reality Test asks whether rollback remains possible while restoration cost is still manageable. The Exception Re-entry Test asks whether anomalies, minority cases, complaints, or contrary evidence can materially alter the dominant path. The Authority Distribution Test asks whether multiple actors can materially change the default path, rather than merely advise a centralized revision authority. </p> <p> SΔϕ-30 introduces the concept of <strong>closure drift</strong>: the process by which a system moves from governable default toward closed-default regime without openly announcing closure. Closure drift often appears as convenience, stability, safety, efficiency, openness, or participation while revision becomes inert, rollback becomes symbolic, exceptions are merely logged, and revision authority remains centralized. </p> <p> The package includes canonical PDF, Markdown, and TXT versions; AI quickstart; core declaration; minimal definitions; formal vs operational editability; editability-real formula; Revision Reality Test; Rollback Reality Test; Exception Re-entry Test; Authority Distribution Test; closure drift; diagnostic summary table; closed-default signal catalog; declared openness vs operative closure; diagnostic audit protocol; case patterns for declared participation and formal appeal; templates; machine-readable JSON and YAML files; boundary constraints; citation metadata; package manifest; and checksums. </p> <p> This package should not be used to infer closure solely from the existence of a default, to claim that every stable default is closed, or to function as a moral judgment engine before applying the four diagnostic tests. It should also not treat feedback collection as exception re-entry, consultation as distributed authority, an appeal button as rollback reality, or formal reversibility as timely rollback. SΔϕ-30 is an operational diagnostic package for distinguishing formal openness from operational re-openability in default governance. </p>
