SafeGate v6 / Final Public Review Index / V6 Freeze

From controlled evidence to compliance-grade trust direction.

SafeGate v6 turns the V5 merchant/API architecture into a compliance, audit trail, edge-case, security, agent-ready, and selective disclosure direction.

V6 does not claim production API readiness. It defines the trust architecture needed before stronger working-proof or production claims.

30-Second V6 Summary

SafeGate V6 answers this question: Can payment-triggered trust be verified, audited, hardened, consumed by agents, and selectively disclosed without exposing secrets?

V6 direction: receipt verification → audit event → edge-case safety → evidence timeline → hardening → agent-safe response → selective disclosure.

1. What V6 Adds

Audit trail planning for every post-payment trust step.
Working receipt verify endpoint direction without production API overclaim.
Edge-case test plan for invalid, duplicate, delayed, ambiguous, rate-limited, and unsafe states.
Minimal evidence timeline / audit viewer: event, time, result, boundary.
Security and compliance hardening controls before stronger claims.
Agent-ready payment verification boundaries.
Selective disclosure / Reg-Shield direction for auditable privacy.

4. V6 Reviewer Reading Path

Start with v6.0 Audit Trail Planning.
Review v6.1 Working Receipt Verify Endpoint Direction.
Open v6.2 Edge Case Test Plan.
Test v6.3 Evidence Timeline / Audit Viewer.
Review v6.4 Security & Compliance Hardening.
Finish with v6.5 Agent-Ready and v6.6 Selective Disclosure.

5. What V6 Does Not Claim

SafeGate v6 is a public architecture, direction, and review package. It does not claim a production public API, production selective disclosure, legal compliance certification, regulator approval, ZK implementation, real API key issuance, production merchant account creation, backend secret exposure, or Pi Mainnet settlement proof.

Current evidence remains Pi Testnet controlled post-payment trust flow.

6. Strategic V6 Result

SafeGate has moved from V5 merchant/API architecture into V6 trust architecture depth: audit trail, edge-case behavior, evidence timeline, security hardening, agent-safe verification, and auditable privacy direction.

This prepares the ground for the next phase: stronger working proof, backend-supported receipt verification, broader pilot evidence, and later reputation / trust registry architecture.
