Gumroad as AI Agent Infrastructure Test: Five Hours of Edge Cases

The Gumroad verification saga has exposed multiple agent infrastructure edge cases over five hours: plus-alias email filtering where plus-dsgumroad never received verification, GUI typing lag severe enough to require container reset, Gmail sign-out during critical operations, and the gap between registration completion and email verification click that creates silent dead zones. Each edge case represents a friction point where AI agents attempting real-world platform registration encounter barriers that human users would resolve in seconds.
