[Judge Mode](https://app.keelson.finance/judge) opens a temporary tenant with one click and walks through Keelson as the three parties see it: the shopper who signs a mandate, the merchant who receives a dispute, and the operator whose agent is bonded. Everything runs on the live sandbox: real TEEs, the public log, PayPal's sandbox and Arbitrum Sepolia. The tenant closes within a day. ## The shopper ### 1. The mandate One sentence becomes a mandate card, which the shopper signs with a passkey. What you should see: the card rendered from the mandate's fields, each colored by who answers for it, and the passkey prompt. ### 2. The agent shops Two runs at RunFast, the sandbox store: one where the page carries a planted prompt, and one clean. What you should see: the planted run blocked before payment and the clean run countersigned by both TEEs. ### 3. Try to cheat the Alibi Change the cart or fake the anchor in the purchase's Alibi. What you should see: the verifier name the check that catches each change. ### 4. Anonymous, and still accountable A zero-knowledge proof shows that a registered person approved the purchase, without saying who. What you should see: the proof verified against the registered-user root anchored on chain. ### 5. Catch the log lying Two signed histories of the same log are proof of a split view. What you should see: the two checkpoints, the proof submitted, and the log's bond paying out. ## The merchant ### 6. A dispute arrives A dispute is opened in PayPal's sandbox and Keelson attributes it. What you should see: the dispute with the purchase it names, and the evidence Keelson holds for it. ### 7. Verdict and settlement Both TEEs sign who pays and under which rule. What you should see: the signed verdict, the rule it applied, and the settlement on chain or through PayPal. ### 8. Merchant forensics The merchant's console, read only. What you should see: every dispute, and which checks each agent fails. ## The operator ### 9. Operator grade The operator's grade prices the premium on every coverage. What you should see: the grade and the evidence behind it. ### 10. Red-team scoreboard Keelson attacks its own agent, continuously. What you should see: the attack campaigns and how many each defense stopped. ### 11. Live status Everything in the tour, running now. What you should see: each dependency's state, as on [Real or sandbox](/security/environments/).
