APR-Lite Phase 33: Ed25519 Sovereign Officer Identity

Key Points

The aim is to enhance officer identity security in substrate governance by transitioning to public-key signatures.
Upgrade from shared-secret authentication to per-officer public-key signatures.
Generate sovereign officer keypairs on officers' devices, only storing registered public keys on the substrate.
Implement signature verification through mediation receipts that confirm signature validation against public keys.
Develop a comprehensive pre-Phase 34 validation suite with specified passing checks and documented gaps.
Introduced a more secure authentication method with per-officer public-key signatures.
Achieved validation suite with 14 successful checks and identified 9 gaps for future work.
Ensured the system retains an additive-only constraint in all components.

Abstract

This document is the canonical technical record for APR‑Lite Phase 33, which upgrades officer identity in the substrate governance platform from shared‑secret authentication to per‑officer public‑key signatures. Phase 33 introduces sovereign officer keypairs generated and retained on the officer’s device; the substrate holds only registered public keys and never stores private key material. Mediation receipts now mark actions as signature‑verified only when a cryptographic signature is validated against the officer’s registered public key. Phase 33 also delivers a comprehensive pre‑Phase 34 validation suite (14 passing checks and 9 documented gaps representing forward architectural work items). All components maintain the additive‑only constraint.
