**1) Why Day 7 behavior is high value** - Repeated high-value engagement signals genuine buying intent—active research, not casual browsing. - 重复的高价值互动说明客户在认真评估，购买意向真实，而非随便看看。 **2) Why AI keeps the lead in C Pool** - Score only reaches 34 vs. a 60 threshold; the AI rewards consistency and depth over single-session bursts, so no upgrade yet. - 当前得分34，未达60的升级门槛；AI看重持续深度而非单次热度，因此暂不升级。 **3) Precise nurture actions to trigger now** - Stay in C nurture: send targeted content/case study, trigger a soft sales check-in task—hold the formal B2B proposal until score nears 60. - 保持C池培育：推送针对性案例内容，安排轻量销售跟进；正式方案暂缓，待分数接近60再发。 **4) How this supports the 100-unit distribution inquiry** - Sustained engagement builds qualification data; when the lead crosses 60 → C→B upgrade → proposal + follow-up fire, giving sales the intent signals to pursue the 100-unit deal at the right moment. - 持续互动积累资质数据；一旦过60分触发C→B升级，自动发方案与跟进任务，让销售在最佳时机推进100套分销订单。
