**Day 7 Callback Request — Why It Matters** - Callback request signals active buying intent, not passive browsing: the lead is asking for human contact, which historically correlates with 3–5x higher conversion than content views alone. 客户主动要求回电，说明已从"看内容"进入"要人对接"阶段，购买意向明确，转化率通常远高于单纯浏览。 - Day 7 score (77) jumped ~22 points from the Day 1–6 cumulative base (55) — a single high-intent action nearly outscored a week of engagement, showing the AI weights intent signals heavily. 单日高分行为贡献约22分，几乎抵得上一周的累计行为，说明AI对"高意向动作"赋予了很高权重。 **Why C → B Upgrade** - Score crossed the 60 threshold (from 20 on Day 1 to 77 on Day 7), triggering the automated pool upgrade rule. 分数从20升到77，越过60的升级线，系统自动将其从C池升至B池。 - B Pool = "actively engaged, sales-ready" segment; the upgrade reflects consistent engagement plus a decisive intent signal, not a one-off event. B池代表"活跃且有销售就绪度"的客户群，升级依据是持续互动加关键意向信号，而非偶然行为。 **Triggered Nurturing Actions** - Send a tailored B2B training proposal (multi-module, volume-pricing indicative) within 24 hours. 24小时内推送定制化企业培训方案（含模块与批量报价参考）。 - Create a sales follow-up task and route the callback to the success team with a priority flag. 生成销售跟进任务，将回电请求以高优先级派给客户成功团队。 - Log the lead in CRM as "B — proposal sent" for pipeline tracking and next-stage scoring. 在CRM中标记为"B—已发方案"，纳入管道跟踪与下一阶段评分。 **Path to the 100-Unit Inquiry** - The callback + proposal combo is the standard bridge from interest to volume commitment; B Pool treatment keeps cadence tight until score approaches 120 (A Pool). 回电加方案是"兴趣→批量承诺"的标准转化路径；B池节奏管理将持续推动分数逼近A池的120门槛。 - At A Pool, the system escalates to senior sales and multi-stakeholder engagement — the right setup to scope and close a 100-unit distribution deal. 进入A池后升级至资深销售与多方决策人触达，为谈定100套分销订单铺路。
