Implements complete registration + login flow: - Registration: Client/Server exchange PCG seeds (once) - Login: Single-round (pcg_index + masked_input → evaluation) New types: - VoleRegistrationRequest/Response - PCG seed exchange - VoleUserRecord - Server's stored user data - VoleClientCredential - Client's stored credential - VoleLoginRequest/Response - Single-round login messages Key properties: - Single-round online phase after registration - Perfect privacy (server cannot fingerprint users) - ~4KB round-trip (vs ~8KB for Ring-LPR) - Deterministic OPRF output (LWR guaranteed) - Wrong password correctly rejected All 211 tests passing.
