- **Why Day 7 engagement is high value** → Repeated sessions signal active intent, not passive browsing; repeat interactions are the strongest predictive signal in B2B training buying cycles. 重复的高价值互动说明客户有明确意向，而非随便浏览；在B2B培训采购中，重复互动是最强的预测信号。 - **Why AI keeps the lead in C Pool** → Score rose from 10 to 11, far below the C→B threshold of 60; single-day activity lifts score marginally, but cumulative evidence is still too thin for upgrade. 分数从10升到11，远低于C→B的60分门槛；单日活跃只带来小幅加分，累计证据仍不足以升级。 - **Precise nurturing actions to trigger** → Send a tailored 100-unit distribution proposal outline, schedule a sales follow-up task within 24h, and add the lead to a targeted case-study email sequence. 触发定制化100套分销方案概要、24小时内安排销售跟进任务，并将该线索加入针对性案例邮件序列。 - **How this supports the 100-unit inquiry** → The proposal anchors the conversation at the customer's stated volume, while follow-up converts repeat interest into a qualified opportunity without premature sales pressure. 方案以客户提出的100套规模为锚点推进对话，跟进任务把重复兴趣转化为合格商机，同时避免过早销售压力。 - **Business outcome** → Faster response on high-intent signals improves pipeline quality and shortens the C→B conversion path, protecting sales capacity for genuinely qualified deals. 对高意向信号快速响应可提升商机质量、缩短C→B转化路径，把销售资源留给真正合格的商机。
