1. **High-Value Behavior Analysis:** Repeated high-value engagement on Day 7 (e.g., multiple deep-content views or video completions) signals strong, concentrated interest. This pattern is more predictive of buying intent than sporadic, low-value clicks. *高价值行为分析：* 第7天重复的高价值互动（如多次深度内容浏览或视频完成）表明强烈且集中的兴趣。这种模式比零散的低价值点击更能预测购买意向。 2. **AI Pool Upgrade Logic:** The cumulative score from Days 1-6 was 0, but the concentrated Day 7 activity pushed the score past the C→B threshold of 60. The AI interprets this sudden, high-quality engagement as a significant intent signal, warranting an upgrade to a warmer nurture pool (B). *AI 池升级逻辑：* 第1-6天的累计分数为0，但第7天的集中活动使分数超过了C→B的阈值60。AI将此突然的高质量互动解读为重要的意向信号，因此有理由升级到更热的培育池（B）。 3. **Triggered Nurturing Actions:** Upon upgrade to Pool B, the system should automatically trigger a personalized proposal (e.g., a tailored training package overview) and create a high-priority task for the sales team to conduct a qualified follow-up call within 48 hours. *触发的培育行动：* 升级到B池后，系统应自动触发一份个性化提案（例如，定制的培训套餐概述），并为销售团队创建一个高优先级任务，要求在48小时内进行合格的跟进电话。 4. **Business Impact on Conversion:** This automated response captures momentum. By immediately providing a proposal and prompting sales outreach, the system directly supports converting this engaged lead into a concrete 100-unit distribution inquiry by aligning the next step with their demonstrated interest. *对转化的商业影响：* 这种自动化响应抓住了势头。通过立即提供提案并提示销售跟进，系统通过将下一步行动与其已表现出的兴趣对齐，直接支持将这个高参与度线索转化为具体的100套分销询盘。
