**1) Why Day 7 behavior is high value** - Requesting a callback signals active buying intent, not passive browsing. - 主动要求回电 = 明确采购意向，而非随便看看。 **2) Why AI upgrades C → B** - Score jumped 56 → 84 (predicted), crossing the 60 threshold — behavior-driven, not time-driven. - 评分从56跃升至预测84，跨过60阈值，属于行为驱动升级。 **3) Precise nurturing actions to trigger** - Auto-route to success-team queue, send tailored B2B proposal, and create a sales follow-up task within 24h. - 自动分配成功团队、推送定制化B2B方案，并在24小时内生成销售跟进任务。 **4) Business impact on pipeline** - Higher-intent lead → faster response, better conversion rate, larger deal potential (100-unit inquiry). - 高意向线索 → 响应更快、转化率更高，并有能力承接100套级别的大单。 **5) Note on B → A gap** - At 84 vs. threshold 120, further high-value signals are still needed; keep monitoring to avoid premature handoff. - 84分离120分升级线仍有差距，需持续监测高价值信号，避免过早移交。
