sec SCITT VCP GQRVP Verifiable Convergence Protocol (VCP) defines minimal data types and APIs for autonomous agents to achieve epistemic convergence without centralized truth arbiters. VCP is transport-agnostic, blockchain-agnostic, and model-agnostic. The key invariant: C(manipulation) > C(validation) for all Claim objects.

Introduction As AI transitions to autonomous agents, lack of verifiable trust is a bottleneck. VCP provides minimal protocol for claims, actions, and traces.

Conformance A system is VCP-Compatible iff it implements 4 Core Endpoints, confidence via MWU plus Gossip as per GQRVP, Actions reference Claim as basis, and Trace is immutable and content-addressed.

Core Types Claim is atomic unit: claim_id, content, provenance, confidence 0.0-1.0, trace. Attestation is signature over Claim by DID. Action is state change grounded in Claims. Gateway MUST reject if basis empty or confidence less than 0.731. Trace is immutable record with final_confidence and merkle_root. Formal-to-epistemic threshold theta_critical equals 0.731. Empirical sybil-10x-g1.5 trace shows 30 scores above threshold.

Core Endpoints POST /v1/claim, GET /v1/claim/{id}, POST /v1/action/verify, GET /v1/trace/{id} over HTTPS, application/json.

GQRVP Security Parameters MUST use eta equals 0.2, gamma equals 1.5, eps equals 0.1. Provides 67 percent Byzantine resilience.

IANA Considerations No actions.

Security Considerations VCP guarantees cost of manipulation exceeds cost of validation given honest supermajority.
