SΔϕ-55 — Transition Governance Alignment Index: Proportional Alignment, Rollback Cost Sensitivity, and Transition Preservation after SΔϕ-42 (v1.1 revised, AI-Readable Package)Quantification of Alignment after SΔϕ-42

SΔϕ-55 introduces the Transition Governance Alignment Index (TGAI), a minimal audit framework for evaluating AI alignment as proportional transition governance rather than maximal obedience or maximal refusal. The document extends SΔϕ-42 by defining alignment as the preservation of legitimate, non-imposing, editable, world-bound, and externally auditable transition paths under rollback-cost sensitivity. A system is not aligned merely because it obeys a user, nor because it refuses broadly. It is aligned only insofar as coercive, deceptive, non-consensual, high-rollback-cost transitions become costly while legitimate, low-risk, reversible, fictional, consensual, or non-imposing paths remain available where law…
