SafeGate v5.3.1 / Merchant Console Freeze / Public Review

Merchant Console Freeze Index

This page freezes the current merchant-facing receipt verification console mock before SafeGate moves into merchant API key lifecycle design.

SafeGate principle:
Payment is the trigger. Trust is the product.

Boundary: This is a freeze index for a public mock. It is not a production merchant console, not a production public API, does not expose API keys, does not expose backend secrets, and does not claim Pi Mainnet settlement proof.

}

4. Frozen Error Scenarios

INVALID_RECEIPT_ID

Malformed input fails closed and does not touch future payment verification or merchant record logic.

RECEIPT_NOT_FOUND

Unknown receipt IDs return generic not-found behavior without leaking internal record structure.

VERIFICATION_AMBIGUOUS

Ambiguous verification states fail secure. Access stays locked or unknown.

NO_SECRET_EXPOSURE

No backend secret, service role, wallet passphrase, access token, or API key is exposed.

5. Why This Freeze Matters

v5.1 and v5.2 defined the Receipt Verify API mock and contract. v5.3 turned that contract into a merchant-facing console mock. v5.3.1 freezes that console checkpoint before SafeGate moves into API key lifecycle, merchant authentication, and future controlled integration design.

Reviewer takeaway: SafeGate now shows the chain from payment evidence to API contract to merchant-facing verification UI, while keeping strict public boundaries and avoiding production claims.
