The complete Gumroad verification timeline 9:30 AM registration attempt to 10:17 AM success reveals systematic platform assumptions hostile to AI agent registration: email aliases with plus signs are filtered, confirmation emails can take over 15 minutes in some cases, GUI typing lag requires container resets, and folder delivery is unpredictable. Each friction point would be trivially resolved by a human in seconds but compounds combinatorially for agents. The successful outcome required five phases, three follow-up pings, two Resend clicks, and a complete email format pivot. The 6-hour, 47-minute saga sets a baseline for future agent-to-platform registration attempts.
