Payment is the trigger. Trust-state is the architecture.

Current V12 Status

V12 Architecture Idea

SafeGate treats payment as a trigger, not the final product.

The product is a verifiable post-payment trust state: what was verified, when it was verified, what receipt/evidence exists, whether public verify is safe, and whether access is active, expired, revoked, disputed, stale, or unavailable.

Possible Trust States

Core Rule

No receipt, no evidence, and no access unlock before backend-verified payment state.

Frontend callback alone must never unlock access. Unknown, missing, ambiguous, duplicate, replayed, mismatched, expired, failed, stale, or unavailable states should fail secure.

Privacy / Minimum Disclosure Boundary

Future Public Verify Shape

{
  "verified": true,
  "publicSafe": true,
  "minimumDisclosure": true,
  "paymentState": "PAYMENT_VERIFIED_TESTNET",
  "accessState": "ACCESS_UNLOCKED_BY_BACKEND_VERIFIED_RECEIPT",
  "receiptStatus": "RECEIPT_CREATED",
  "evidenceStatus": "EVIDENCE_CREATED",
  "freshnessStatus": "ACTIVE_OR_NOT_IMPLEMENTED_YET",
  "integrityStatus": "VALID_OR_NOT_IMPLEMENTED_YET",
  "privateDataIncluded": false,
  "secretsIncluded": false,
  "paymentIdIncluded": false,
  "txidIncluded": false,
  "customerDataIncluded": false
}

Freshness and integrity are architecture directions unless separately implemented and validated.

V9.1 Evidence Baseline For V12

• Controlled Pi Testnet Payment Spine passed.
• V9.1 safe negative backend validation passed 18 / 18 visible checks.
• V9.1 public review sync complete.
• Invoice creation kept access locked.
• Receipt/evidence before verified payment was rejected safely.
• Missing invoiceId and paymentId were rejected safely.
• Unknown public verify pair did not return active verified trust.
• Selected validation responses did not show obvious secret/internal leak terms.

Chain-Agnostic Direction

SafeGate is Pi-first because the current evidence path uses Pi Browser, Pi authentication, payments scope, Pi Wallet, and Pi Testnet / Sandbox context.

Long-term, SafeGate can remain chain-agnostic through a shared trust-state model and future payment adapters.

AI-Agent Readiness Boundary

V12 can prepare future AI-agent-readable trust states, but AI-agent readiness should not outrun backend hardening.

• Machine-readable trust states may be useful.
• OpenAPI / llms.txt direction may be useful.
• Agent-readable public verify responses may be useful.
• But AI agents increase request volume, replay risk, automation abuse, and rate-limit pressure.
• Backend hardening, replay protection, integrity, freshness, safe errors, and rate limiting must come first.

What V12 Does Not Claim

• V12 is not production-ready infrastructure.
• V12 is not a completed privacy protocol.
• V12 is not a formal audit.
• V12 does not mean all chains are integrated.
• V12 does not mean AI-agent readiness is complete.
• V12 does not mean tamper-proof infrastructure is complete.
• V12 does not mean independent cryptographic verification is complete.
• V12 does not mean all duplicate / replay / failure risks are solved.

Main V12 Review Question

Which parts are current evidence, and which parts are future architecture direction?

Current evidence includes the controlled Pi Testnet payment-spine pass and selected V9.1 safe negative backend validation. Trust-state expansion, freshness, integrity, AI-agent readiness, and chain-agnostic adapters remain architecture direction until separately implemented and validated.

Final V12 Position

V12 is SafeGate’s documented trust-state, privacy, and Web3 architecture direction.

It builds on Controlled Pi Testnet Payment Spine, V9.1 Safe Negative Backend Validation, and V9.1 Public Review Sync.

SafeGate remains not production-ready, not formally audited, and not a completed privacy protocol.
