- **Day 7 behavior = explicit intent signal.** Completing a post-video survey shows active engagement, topic fit, and willingness to share needs — stronger than passive views, but still early-stage. - 第7天完成视频后问卷，说明客户在主动表达兴趣和需求，比单纯观看更能体现购买意向，但仍处于早期阶段。 - **AI score 32 < 60, so C Pool remains correct.** The behavior adds only +2 points because it is one signal, not yet validated by repeat visits, proposal views, or buying-committee involvement. - AI评分32分，低于升级阈值60分，因此继续留在C池；问卷只加2分，因为单一行为还不足以证明持续采购意图。 - **Trigger lightweight nurturing, not sales handoff.** Send a thank-you + tailored resource, recommend a relevant case study, and set a 3–5 day follow-up task. - 应触发轻量培育动作：感谢回复、发送定制资料、推荐相关案例，并设置3–5天后的跟进任务。 - **Hold B2B proposal until score crosses 60.** Proposal creation should be reserved for B Pool or A Pool to protect sales efficiency and avoid premature discounting or over-servicing. - 暂不生成B2B提案，等评分超过60分再升级；提案应留给B池或A池，避免销售资源浪费和过早让价。 - **Path to 100-unit inquiry:** survey completion → targeted case study → repeat engagement → score ≥60 → B Pool → proposal + sales follow-up → volume discussion. - 转化到100套采购询盘的路径：问卷完成 → 精准案例触达 → 多次互动 → 评分≥60 → 升级B池 → 提案+销售跟进 → 进入批量采购谈判。
