1) Day 7's repeated high-value engagement (e.g., multiple case study views, pricing page visits) signals a concentrated, active evaluation phase, moving the lead from passive to active interest. * 第7天的高价值重复互动（如多次查看案例研究、访问定价页面）表明客户进入了集中的主动评估阶段，从潜在兴趣转向了实际考量。 2) The AI score (0) remains below the C→B upgrade threshold (60). This indicates that while engagement is strong, the cumulative behavioral data and predictive signals are still insufficient to confidently classify this lead as a high-probability, sales-ready opportunity. * 人工智能评分（0分）仍低于C到B级的升级阈值（60分）。这表明，虽然互动积极，但累计的行为数据和预测信号仍不足以将其可靠地归类为高概率、可立即跟进的高意向商机。 3) The system should trigger a **personalized follow-up task** for the sales team (e.g., "Call to discuss specific case studies viewed") and an automated **educational nurture email** with relevant content. A full proposal is premature at this C-pool stage. * 系统应触发一项**个性化的销售跟进任务**（例如，“致电讨论客户查看的具体案例研究”）和一套自动的**教育培育邮件**。在C级池阶段直接发送提案为时过早。 4) This approach qualifies interest early, provides targeted information to build trust, and positions the sales team for a consultative conversation. This nurtures the lead toward a concrete, large-scale inquiry (e.g., 100 units) by addressing specific needs before the pricing discussion. * 该方法能早期识别意向，通过提供针对性信息建立信任，并为销售团队创造顾问式对话的机会。通过在讨论价格前解决具体需求，引导客户最终提出具体的大规模询盘（如100套）。
