1) **High-value behavior on Day 7:** Repeated engagement (e.g., multiple page views, video watches) signals active, focused interest, not passive browsing. This indicates the lead is in an active research or evaluation phase, making them a higher-quality prospect for sales outreach. *高价值行为分析：* 在第七天的重复互动（如多次浏览页面、观看视频）表明客户处于主动研究和评估阶段，而非随意浏览。这标志着该线索具有更高的销售转化潜力。 2) **No pool upgrade (C → B):** The AI score (0) remains far below the upgrade threshold (60). A single day of high engagement, while positive, is insufficient to overcome a low cumulative score. The system requires sustained interest over time to signal true buying intent and justify a pool upgrade. *未升级原因分析：* AI评分（0分）远低于升级阈值（60分）。单日的高互动度虽积极，但不足以弥补累计评分的不足。系统需要持续的兴趣信号来确认真实的购买意向，才能进行池升级。 3) **Triggered nurturing actions:** The system should trigger a **personalized follow-up task** for the sales team (e.g., "Lead showed concentrated interest on Day 7—reach out with specific content related to their viewed topics"). A **B2B proposal is not yet warranted** as the score is too low, but an **automated, value-added email** (e.g., a case study or expert article on the topics they engaged with) should be sent to nurture further. *触发的培育行动：* 系统应触发一项**个性化的销售跟进任务**（例如：“该线索在第7天表现出集中兴趣——根据其浏览内容进行针对性联系”）。由于评分过低，**暂不触发B2B提案**，但应发送一封**自动化的增值邮件**（例如，与其互动内容相关的案例研究或专家文章），以进一步培育。 4) **Path to a 100-unit inquiry:** This approach nurtures the lead with relevant content post-engagement, increasing the likelihood of further interactions. By scoring subsequent engagements, the lead can cross the 60-point threshold, upgrade to Pool B, and trigger a **targeted proposal for bulk training solutions**, directly paving the way for a high-volume distribution inquiry. *通向100套订单问询的路径：* 此方法在客户互动后提供相关内容进行培育，增加其进一步互动的可能性。通过对后续互动评分，该线索有望突破60分阈值，升级至B池，并触发**针对批量培训方案的定向提案**，从而为达成大宗订单问询铺平道路。
