The diagram
Every HTTP response is a decision.
Send a request from the rail, or call this page's live URL with curl, and watch the flowchart decide the status one question at a time.
WebMacha sandbox
A PUT to an existing resource reaches O14, which asks whether applying it would conflict with the resource's current state. The resource says true, perhaps because someone else changed it first, so the answer is 409 Conflict.
