🛠 PATCH & PROVE · WEB3

Repair the success banner

Finding a bug is only half the story. Change the repair rules, then test whether your patch fixes the failure and keeps valid behaviour working. Every run starts with fresh simulated data.

Contract: Show Payment complete only for a confirmed transaction on Preview. Pending, rejected, and wrong-network transactions must never show success.

Build your repair
Run the starting rules to uncover the failure, then try a repair.
