- **Day 7 survey = high-intent signal.** Completing a post-video survey shows active engagement, not passive viewing—early buying-committee interest in training content. 完成问卷是高意向信号：客户不只是看视频，而是主动投入时间反馈需求，说明已有初步采购兴趣。 - **AI keeps lead in C Pool: score 25 vs. threshold 60.** Predicted gain (+5) is modest; cumulative engagement is still early-stage, so upgrade would be premature and hurt scoring reliability. AI 仍留在 C 池：预测分 25 远低于升级线 60，累计互动深度不足，过早升级会降低评分可信度。 - **Trigger micro-nurturing, not sales handoff.** Send a personalized content follow-up (e.g., short case study on team training ROI) and log the survey responses for segmentation; no B2B proposal or sales task yet. 触发轻量培育而非销售介入：发送定制化案例内容并归档问卷数据用于分层，暂不生成正式方案或销售跟进任务。 - **Build a behavior bridge toward 100-unit inquiry.** Use survey answers to qualify team size and training needs, then queue a targeted nurture sequence (e.g., volume-licensing content) to push score toward 60. 用问卷信息判断团队规模与培训需求，设计面向批量采购的内容序列，逐步把分数推向 60 的升级线。 - **Business outcome:** Controlled C-pool nurturing protects sales capacity, while structured qualification prepares a credible path to a B-pool upgrade and a 100-unit distribution conversation. 业务结果：C 池精细培育节省销售资源，同时通过结构化资格判断，为升级 B 池和 100 套分销洽谈打好基础。
