**Day 7 – Callback Request: High Intent, Still Early Stage** - **Behavior signal is strong:** Requesting a callback = active buying intent, not passive browsing. It signals the lead wants human contact and may have budget/timeline in mind. - 主动要求回电＝明确购买意向，不是随便逛逛；说明客户想谈预算和时间表了。 - **Score stays low → no upgrade:** AI weighs *depth* of engagement, not just one action. A single callback request moves score 10 → 13, far below the 60 threshold. Cumulative history (Days 1–6) is still weak. - 单次行为加分有限；AI看的是整体互动深度，10分到13分离60分门槛还差很远，前6天积累不足。 - **Why C Pool persists:** Low cumulative engagement + no repeat high-value actions. The callback is a *start* signal, not a *ready-to-buy* signal. - 一次回电只是“兴趣起点”，不是“成单信号”；所以继续留在C池孵化。 - **Precise actions to trigger now:** - Sales rep callback within 24h to qualify needs and timeline. - Send tailored *training program overview + case studies*, not a full proposal yet. - Log a follow-up task and entry-level pricing sheet (low-commitment). - 24小时内回电确认需求和时间表；先发方案概览+案例，不急着报正式提案；记录跟进任务。 - **Path to 100-unit distribution inquiry:** Nurture builds trust and engagement score → crossing 60 upgrades C → B → triggers formal B2B proposal + distribution/pricing discussion. Each touch raises score and pipeline quality. - 持续互动拉高分数→过60分升级到B池→触发正式提案和分销/报价谈判；逐步把兴趣转化为100套的分销询盘。
