A PURCHASE YOU CAN INSPECT
Follow the Shopify purchase, inspect the risk evidence, and verify what the agent was allowed to do.
PRIVATE DEMO
Use the demo password from the Kernvel vault.
01 / DESIGN THE RUN
Digital test product · Shopify Test payment gateway
02 / EXECUTION GATE
Start a run to get the actual checkout amount and evaluate the demo policy.
Test card: 1 = success, 2 = decline. Use a future expiry, any 3-digit security code and “Bogus Gateway” as the cardholder.
A development store may ask for its storefront password, stored alongside the demo password in the vault.
03 / EVIDENCE INSPECTOR
Live protocol exchanges will appear here.
{ "status": "waiting for checkout" }04 / CHALLENGE THE AUTHORIZATION
Each probe changes a copy of the authorization. It never attempts a payment.
Real Shopify UCP checkout creation and browser checkout, plus cryptographic AP2 v0.2 verification in our own reference adapter. The same signed risk attestation is carried in the adapter checkout signals and AP2 payment mandate.
Shopify has not been shown to accept or enforce this AP2 mandate. The adapter controls its own checkout handoff. A buyer who has the Shopify checkout link can complete or change that checkout outside our gate. Rules are illustrative, not a trained fraud model. All signing roles run in the lab; this is not a production wallet or independent proof of buyer identity.
