Age Verification and the Engineering Prevention of Structural Slippage

The causal mechanism of structural slippage is real (a strong tendency, reversible by countervailing institutional pressure), the shared condition across historical expansion cases is the simultaneous absence of legal constraint and technical binding, and the four prevention tools constitute a cross-tier combination rather than mutually exclusive options. The present article extracts a common pattern from four historical cases (Aadhaar, SSN, eIDAS, China real-name) and two critical counter-examples (Austria sourcePIN, Germany nPA), derives the causal mechanism through a triangulation of path dependency, infrastructure studies, and institutional layering, evaluates the prima facie evidence offered by the EUDI ARF and California AB 1043, responds to two objections from nihilism and public choice, and concludes with a three-tier Minimum Viable Slippage Resistance (MVSR) clause.

Why DNS Escaped State-Centric Governance but Digital Identity Has Not: A Historical Sociology of Trust Roots

The present analysis formalizes DNS non-state governance as four conjunctive preconditions P_DNS = {P1 Postel-jar academic community, P2' U.S. strategic withdrawal, P3' technical-neutrality discourse as deliberate construction, P4' Stewardship Transition as a political product barely cleared through multiple veto points}. The Historical Mismatch hypothesis (HM) shows that all four preconditions fail to hold in the digital identity domain P_ID as of 2025. HM shares a conjunctive-necessary-condition structure with the H1' three-wall argument of article 03, the T three-element argument of article 04, the IT' impossibility triangle of article 05, the CB-Justice D1*∧D2* of article 06, and the SRP of article 07, though operating at the level of historically contingent necessary conditions for governance. Comparison of four cross-national governance models shows that the IATA + ICAO and SWIFT + CPMI dual-track models yield the highest fit; ICANN is not the template—the four-layer governance framework FTLA = (G_industry, G_state, G_recognition, G_oversight) is. Within specific sub-domains (PSE / Vocdoni / Rarimo / DIF) a loose autonomy position within the G_industry layer may be preserved, but boundary conditions B2–B4 all fail, precluding expansion into full-scale replication of the DNS model.
