**Scenario: C → B Upgrade, Day 7 Contact Click, Predicted Score 75** - **Day 7 behavior is high-intent, not passive.** Clicking contact info signals an active move toward human engagement—far stronger than a page view or video watch. It typically precedes a buying conversation. 点击联系方式是主动意向信号，代表客户正从"了解"转向"对接"，比浏览页面或看视频更有购买前兆价值。 - **AI upgrade logic: cumulative + recency.** Days 1–6 built a base of 55; the Day 7 high-value action pushed the predicted score to 75, crossing the B threshold of 60. Score reflects both accumulating interest and fresh intent. 前6天累计55分打底，第7天的高价值行为把预测分推到75，越过B池60分门槛。评分同时反映"持续兴趣"与"最新意向"。 - **Triggered actions should match the B-pool tier.** Route to a sales rep, send a tailored B2B proposal or course catalog, and create a follow-up task within 24–48h while intent is warm. No full executive escalation yet—that waits for A pool (120). 应转交销售、推送定制化培训方案或课程目录，并在24–48小时内创建跟进任务，趁热度未退。暂不升级至高管层，留待进入A池（120分）时处理。 - **Path to a 100-unit distribution inquiry.** A contact click on a bulk training interest maps well to a multi-seat / distribution deal. Timely proposal + sales follow-up converts intent into a scoped inquiry; continued engagement drives score toward A. 对批量培训感兴趣的客户点击联系方式，很可能对应多渠道/多席位分销大单。及时方案+销售跟进可把意向转化为正式询盘，持续互动将分数推向A池。 - **Business impact.** Faster C→B routing shortens response time, raises pipeline quality, and lifts conversion on larger deals—improving sales efficiency per lead. 加速C→B流转可缩短响应时间、提升商机质量，并提高大单转化率，从而提升单条线索的销售效率。
