- **Why Day 7 is high-value:** A completed post-video survey is an explicit intent signal — the lead invested time and shared preferences, which correlates with higher engagement and fit for the 100-unit scenario. 完成视频后问卷是高价值行为：客户主动投入时间并透露需求偏好，说明购买意向和匹配度都在升高。 - **Why still C Pool:** Predicted score of 29 is well below the C→B threshold of 60, so AI sees early interest but not enough cumulative evidence to justify sales resources. 预测分仅 29，远低于 C→B 的 60 分门槛；AI 判断兴趣已出现，但证据不足以升级、避免浪费销售资源。 - **Precise triggered actions:** Send a lightweight, survey-personalized content follow-up (case study + 100-unit pricing teaser), tag survey answers into CRM, and set a 3-day re-score task — no proposal or sales call yet. 触发动作应轻量：按问卷偏好推送案例与百人规模报价预告、把问卷答案写入 CRM、设置 3 天后复评任务；暂不创建正式提案或销售跟进。 - **Path to 100-unit inquiry:** Score growth must come from repeat, deeper behaviors (demo request, pricing page visits, multiple stakeholder views); once score crosses 60, upgrade to B and trigger proposal + sales follow-up. 要转化为百人采购询盘，需靠重复且更深的行为拉分（申请演示、访问报价页、多角色浏览）；分数过 60 后升级 B 池，自动触发提案与销售跟进。
