**Day 7 Nurturing Read: Survey Completion → Score 46 → Stays in C Pool** - **Why it's high-value:** A completed post-video survey is an active intent signal — the lead invested time, self-identified needs, and gave qualification data (role, budget, timeline). Passive views don't do this. - 中文：完成视频后问卷是主动意向信号——客户投入时间、暴露需求并提供资格数据（角色、预算、时间表），这是被动浏览做不到的。 - **Why no upgrade yet:** Score rose 43 → 46, but the C→B threshold is 60. One strong behavior isn't enough; AI needs cumulative, multi-touch evidence before reallocating sales resources. - 中文：分数从43升到46，但C→B门槛是60。单次强行为不够，AI需要多次累积证据才升级，避免浪费销售资源。 - **Triggered actions (C-pool, low-touch):** Parse survey answers into the lead profile; route a tailored content follow-up (case study / module outline matched to stated needs); set a re-score checkpoint; alert sales only if score trends toward 60. - 中文：解析问卷答案写入画像；按需求推送定制内容（案例/课程大纲）；设置重新评分节点；仅当分数逼近60时才提醒销售介入。 - **Path to a 100-unit inquiry:** Survey data reveals org size and training scope — use it to size the opportunity, then let B-pool (proposal + follow-up task) trigger once score crosses 60. This keeps pipeline quality high and sales effort proportional to deal potential. - 中文：问卷数据可判断组织规模与培训范围，用于估算商机体量；分数过60进入B池后自动触发提案与跟进任务，保证管道质量并让销售投入与商机潜力匹配。
