- **Day 7 survey = explicit intent signal.** Completing a post-video questionnaire is active opt-in effort, not passive viewing — it reveals topic fit and buying-stage interest, which AI weights heavily. - 填写视频后问卷是主动投入行为，而非被动浏览；它直接暴露兴趣主题与采购阶段，AI 会给予高权重。 - **Score jumped 46 → 54 (+8), but stays below the 60 C→B threshold.** The AI is being deliberately conservative: one high-value signal plus accumulated views isn't enough evidence of deal-readiness; it keeps the lead in C to avoid premature sales load. - 分数从46升至54（+8），仍未越过60的C→B阈值；单个高价值信号加累计浏览不足以证明成交就绪，系统保持C池以避免过早消耗销售资源。 - **Trigger low-cost, high-signal nurturing — not a proposal yet.** Send a tailored content follow-up (e.g., case study / training catalog aligned to the survey answers) and log survey responses into the profile for next-score modeling. - 触发低成本高信号动作：按问卷选择推送定制内容（案例/课程目录），并把问卷答案回写画像用于下次评分；此时不应发方案。 - **Set a near-term score watch (e.g., +6 within 7–14 days).** Any additional high-value act (demo request, pricing page, repeat video) should auto-cross 60 and fire the C→B upgrade with a sales follow-up task. - 设置短期分数监控（7–14天内再+6）；任何进一步高价值行为应自动破60，触发C→B升级与销售跟进任务。 - **Path to the 100-unit inquiry:** sustained, relevant engagement compounds score and informs a B2B proposal sized to cohort/team training needs — the survey data is the key input for scoping that 100-seat distribution conversation. - 通往100人订单的路径：持续相关互动推高分数，问卷数据成为定制B2B方案（按团队/批次培训规模）的关键输入，从而支撑100席位分销洽谈。
