The most dangerous thing in giving advice is dressing hidden assumptions up as confidence. Here the answer is given directly, but the assumptions it rests on are surfaced explicitly and annotated with "what would flip the conclusion"; the tradeoff says when the trade pays off, and the compliance risk is kept as an honest open — this is exactly what the Grounding Contract looks like in a conversation.
给建议最危险的是把藏起来的假设包装成自信。这里 answer 直接给出，但它依赖的假设被显式亮出并标注“什么会让结论反转”，tradeoff 指出何时这笔交易划算，合规 risk 作为诚实的 open——这正是 Grounding Contract 在对话场景的样子。
