Use when the user wants a feature built end to end after answering one round of questions and then being left alone — "turbo", "ask me once, then just build it", "I'll answer up front, don't come back to me", "decide the rest yourself". Not for a run that wants a spec approval and no tests (superb:fast-pipeline), one that approves plans and keeps durable run state (superb:pipeline), or one that needs resumable run files and a quorum (superb:pipeline-auto).
