- **High-value signal:** Post-video survey = active intent + structured self-qualification data (needs, budget, timing) — far stronger than passive views. 视频后问卷是高意向信号，能直接获取需求、预算和时间表，比单纯观看更值钱。 - **Why still C Pool:** Score rose 30→32, but 32 < 60 threshold. Early-scoring model is conservative until cumulative engagement (repeat sessions, proposal views) justifies upgrade. 分数从30升到32，仍低于60的升级线；AI在累计行为不足前保持保守，避免过早升级。 - **Triggered actions:** No proposal yet — instead send tailored case study + short qualification email, tag survey responses to sales, set a 7-day follow-up task. 暂不发正式提案；先发定制案例+简短资格确认邮件，把问卷答案同步给销售，并设7天跟进任务。 - **Path to 100-unit inquiry:** Each interaction (case study open, reply, meeting booked) adds score; crossing 60 auto-upgrades to B and triggers proposal + sales follow-up — converting survey interest into a bulk distribution deal. 每次互动（打开案例、回复、预约会议）都会加分；过60自动升B并触发提案和销售跟进，把问卷兴趣转成100套的分销询盘。
