 "law": "A card builds and checks the analysis — the model, the screen, the thesis. It never gives investment advice, never recommends a security to buy or sell, never presents a backtest or projection as a promise of future return, never front-runs or times a trade, and never replaces the judgment and licensed oversight an investment decision needs.",

  "gives investment advice or tells anyone to buy, sell, short, or trade",
