81. mechanic: choose + justify from: threshold discount ($X off $Y — protects AOV), gift-with-purchase (protects price integrity), bundle, tiered, loyalty-exclusive, or straight % (last resort — say why if chosen).
92. depth + duration: justified against economics; flag if past_promos show escalating depth (discount-addiction warning).
103. fence: who gets it and how it's gated (new customers only? code vs sitewide?) so full-price buyers aren't cannibalized.
114. messaging_frame: value framing that isn't just the number ("stock up for {{occasion}}" vs "20% OFF EVERYTHING").
125. success_math: the exact break-even lift needed given margin impact — show the formula with their numbers.
