- **Day 7 “clicked contact information” is a buying-intent signal, not casual browsing.** It typically means the lead is evaluating how to reach sales/BD for a concrete next step, which is much closer to pipeline than content views or video watches. 中文：第7天点击联系方式属于明确的“购买意向”信号，而非随意浏览；说明客户在主动寻找对接销售/商务的路径，离商机更近。 - **C → B upgrade is justified by score momentum + threshold logic.** Score rose from 20 to 55 before Day 7, and the high-value behavior pushed predicted score to 75—crossing the 60 threshold, so the system upgrades the lead to B rather than waiting for manual review. 中文：从20分到第7天前55分已形成上升趋势，点击联系方式后预测75分，超过60分阈值，因此系统自动从C升到B，而不是等人工判断。 - **Trigger precise B2B nurturing actions immediately.** Recommended actions: assign to sales owner, send a tailored proposal/capability deck, create a follow-up call task within 24 hours, and enroll in B-pool content focused on enterprise training rollout and procurement. 中文：应立即触发精准动作：分配销售负责人、发送定制化方案/能力介绍、24小时内创建跟进电话任务，并进入B池内容培育（企业培训落地与采购流程）。 - **Use B-pool stage to qualify the 100-unit distribution inquiry.** The system should capture company size, training audience, delivery format, budget/timeline, and decision-maker involvement—so sales can validate whether this is a real 100-unit distribution opportunity versus early research. 中文：在B池阶段重点确认企业规模、培训对象、交付形式、预算/时间表和决策人参与度，判断这是否是真实的100单元分销询盘，而非早期调研。 - **Business outcome: higher conversion efficiency and better pipeline quality.** The behavior → score → pool upgrade → triggered sales task flow shortens response time, increases conversion probability, and protects sales capacity for leads showing real deal potential. 中文：业务结果是提升转化效率和管道质量；行为→评分→升池→触发销售任务的闭环缩短响应时间、提高成交概率，并把销售资源集中在真正有潜力的客户上。
