- **Day 7 behavior = real intent data, not vanity traffic.** Completing a post-video survey signals active engagement and willingness to invest time—an early buying signal, though not yet a deal signal. - 完成视频后问卷是高价值行为：主动投入时间、表达意向，比单纯浏览更能说明购买兴趣，但还只是早期信号。 - **Score math explains the C-Pool hold.** Score only moved 20 → 21 (predicted), far below the 60 upgrade threshold; one high-value micro-behavior can't jump 40 points. - 分数从20只到21，离60的升级线差距很大；单个高价值行为不足以支撑跨池升级。 - **Precise trigger: nurture, not sales handoff.** Route the survey responses to the assigned rep for a light-touch follow-up (content-relevant email or call), tag interest topics, and schedule the next nurture touch—no formal B2B proposal yet. - 精准动作是“培育”而非“交接销售”：把问卷结果同步给负责人，做轻量跟进（相关内容邮件/电话）、打兴趣标签、安排下次触达；暂不正式出方案。 - **Guardrail: proposal only at B-Pool threshold.** A B2B proposal or sales follow-up task should fire at score ≥60 (C→B upgrade), keeping sales effort focused on qualified pipeline. - 方案与销售跟进的触发应设在60分（C→B）时，避免销售资源浪费在未成熟线索上。 - **Path to the 100-unit distribution inquiry.** Each high-value interaction adds intent evidence; sustained engagement compounds the score toward 60, upgrading the lead and arming the rep with survey insights for a volume-focused proposal. - 通往100套分销询盘的路径：持续高价值互动累积分数，跨过60后升级并触发方案，销售可结合问卷洞察精准报价。
