- **Day 7 signal = intent + content fit.** Repeat watching of Cultural Insights Demo is active, topic-specific engagement—not passive browsing—so it's weighted heavily. **中文：** 第7天的“反复观看文化洞察演示”是主动且主题精准的意向信号，强度远高于普通浏览。 - **Score math drives the upgrade.** 55 pre-Day-7 → 79 predicted, crossing the 60 threshold; AI moves C→B. Still well below the 120 A-threshold, so it's a qualified but not yet sales-ready lead. **中文：** 分数从55升至预测79，越过60门槛触发C→B升级；距A池120仍有差距，属于“有资格但未完全就绪”。 - **Trigger B-pool actions, not A-pool.** Send a tailored proposal for the Cultural Insights module, schedule a sales follow-up task within 48h, and push a 2–3 email nurture sequence with case studies. **中文：** 触发B池动作：发送文化洞察模块定制方案、48小时内销售跟进、推送2–3封案例型培育邮件。 - **Qualify the 100-unit inquiry.** Ask discovery questions on volume/regions/timeline in the follow-up to validate the deal scope before escalating to A-pool. **中文：** 跟进中用探索性问题确认数量、区域与时间表，验证100套意向真实性，再决定是否升A池。 - **Business impact.** Behavior→score→pool upgrade→targeted proposal shortens sales cycle, improves pipeline quality, and protects sales capacity for genuinely hot leads. **中文：** 行为→评分→升级→精准方案，缩短销售周期、提升线索质量，并让销售资源聚焦真正高意向客户。
