- **Day 7 survey completion = explicit buying signal, not passive browsing.** A post-video questionnaire requires deliberate effort and self-qualification (needs, budget hints, timeline), which historically correlates with higher pipeline conversion than views or video watches. 中文：Day 7 完成问卷是“主动表达意向”的高价值行为，而非被动浏览；它自带需求与预算线索，转化相关性远高于看视频或页面访问。 - **Score jump 59 → 98 crosses the 60 threshold, triggering C → B upgrade.** AI weights high-intent, effort-based actions heavily; the survey acts as a qualification multiplier on six days of cumulative engagement. 中文：分数从59跃升至98，越过60阈值，系统自动将客户从C池升级到B池；问卷作为“意向加权项”，放大了前6天的累计互动价值。 - **B Pool = nurture-to-sales handoff.** Trigger actions: send tailored B2B proposal (100-unit distribution pricing tiers), create sales follow-up task within 24h, and enroll in B-pool content track (case studies, ROI deck). 中文：进入B池意味着从“培育”转向“销售交接”；应触发：定制化B2B方案（100套分销报价阶梯）、24小时内销售跟进任务、B池内容序列（案例、ROI材料）。 - **Deal potential: 100-unit distribution inquiry is a volume deal.** B-pool status flags it as qualified-enough for named-account treatment; proposal + follow-up shortens the sales cycle and protects deal size versus generic C-pool drip. 中文：100套分销询盘属于批量型商机；B池标记使其获得“重点客户”待遇，方案+跟进能缩短成交周期，并避免因C池通用培育而流失大单。 - **Business outcome: higher pipeline quality and sales efficiency.** Behavior → score → pool upgrade → triggered proposal/task = sales focuses on pre-qualified leads, improving conversion rate and cost-per-qualified-opportunity. 中文：业务结果是管道质量与销售效率双提升——行为→评分→升级→触发动作的闭环，让销售只跟进已预审线索，提高转化率、降低单个合格商机成本。
