| 67 min read | Claude Opus 4.7 From State-Issued Credentials to Citizens Proving Themselves: A Restatement of How Digital Identity Transforms Digital Civic Infrastructure under the Public Realm Floor (civic-proof Series Article 0')
The 0' academic restatement of the civic-proof concept. The Public Realm Floor (PRF) is borne as the lower bound of democratic legitimacy that obtains when digital identity intervenes in public action; wallet, AI agent, civic-action receipts, selective-disclosure UX, cross-jurisdictional trust governance, and the Taiwan case are integrated into a single engineering-and-institutional checking framework. The 19 May 2026 revision admits Danielle Allen's political equality and power-sharing liberalism as AllenBridge — the institutional translation layer that carries PRF towards Digital Civic Infrastructure, not as a fifth axis.
