SΔϕ-29 AI-READABLE Package — Editable Default (v1.0)

<p> This record provides the AI-readable structured package for <em>SΔϕ-29 — Editable Default: Minimal Conditions for Distributed Authority, Rollback, and Exception Re-entry after SΔϕ-28 (v1.0)</em>. </p> <p> SΔϕ-29 extends SΔϕ-28 by asking under what conditions a default remains governable rather than absolute. If default power fixes paths by making one continuation cheapest, governance must be redefined as the capacity to keep defaults structurally editable before closure becomes operationally irreversible. </p> <p> The central claim is that a dominant default remains governable only when four minimal conditions are preserved: <strong>Editable Default</strong>, <strong>Distributed Authority</strong>, <strong>Rollback Window</strong>, and <strong>Exception Channel</strong>. In minimal form, <code>D* is governable iff Ed ∧ Ad ∧ Wr ∧ Ce</code>, where <code>D*</code> is the dominant default, <code>Ed</code> is Editable Default, <code>Ad</code> is Distributed Authority, <code>Wr</code> is Rollback Window, and <code>Ce</code> is Exception Channel. </p> <p> SΔϕ-29 does not claim that all defaults are bad. A default may coordinate action, reduce friction, and lower transition completion cost. However, a default becomes power when revision becomes structurally unlikely, authority collapses into one center, rollback becomes only nominal, or exceptions can no longer re-enter the system. The core compression is: <code>Closed default is power; editable default is governance.</code> </p> <p> The package defines Editable Default as a dominant path that can still be revised, contested, bypassed, or reopened. Distributed Authority means that design, revision, appeal, exit, audit, rollback, and exception-review authority do not collapse into a single center. Rollback Window marks the interval in which revision remains materially feasible before restoration cost crosses a threshold. Exception Channel preserves anomalies, minority paths, contrary evidence, edge cases, local knowledge, and contextual exceptions before they are compressed into silence. </p> <p> The package includes a case pattern titled <em>Mandatory AI Image Filtering as Editable Default Test</em>. This case pattern does not declare mandatory AI image filtering to be either censorship or legitimacy. Instead, it treats such a system as a default-governance test: when a technical filtering path becomes mandatory, SΔϕ-29 asks whether the default remains editable, whether authority is distributed, whether rollback remains materially feasible after false positives or false negatives, and whether public-interest, journalistic, educational, evidence-preservation, artistic, or contextual exceptions can re-enter review. </p> <p> The package includes canonical PDF, Markdown, and TXT versions; AI quickstart; core declaration; minimal definitions; editable default, distributed authority, rollback window, exception channel, governable default formula, closed default, default closure regime, rollback threshold, exception re-entry protocol, authority distribution map, and default governance audit files; a mandatory AI image filtering case pattern; templates; machine-readable JSON and YAML files; boundary constraints; citation metadata; package manifest; and checksums. </p> <p> This package should not be used to claim that all defaults are bad, that formal appeal equals distributed authority, that nominal rollback equals an active rollback window, that exception handling is live when non-default signals cannot re-enter, or that efficient default convergence is governance. It also should not be used as a blanket claim that AI image filtering is censorship or legitimacy. SΔϕ-29 is a default-governance audit package for detecting whether a dominant default remains editable before closure becomes operationally irreversible. </p>
