**1) Why the Day 7 callback request is high value** - A callback request is an explicit buying signal — the lead is inviting direct sales contact, not just browsing. - 回调请求是明确的购买信号：客户主动邀请销售直接联系，而不只是浏览内容。 **2) Why AI keeps this lead in C Pool** - Predicted score of 13 is far below the C→B threshold of 60; one high-intent action alone doesn't offset a thin engagement history. - 预测分仅13分，远低于 C→B 的60分门槛；单次高意向行为无法弥补整体互动记录的不足。 **3) What actions to trigger now** - Route to success/sales for a scheduled callback within SLA, confirm needs and decision timeline, and log the call outcome to enrich the profile. - 在SLA时限内安排成功/销售团队回电，确认需求与决策时间表，并记录通话结果以丰富客户画像。 - Do not issue a full B2B proposal yet — send a lightweight agenda/qualification checklist instead. - 暂不发送完整B2B方案，先发送轻量级议程/资格确认清单。 **4) How this converts toward a 100-unit distribution inquiry** - The callback captures scale, audience and delivery constraints; if the need matches volume distribution, the next score jump should cross 60 → C→B upgrade → proposal + sales follow-up tasks auto-triggered. - 回电用于获取规模、受众与交付条件；若需求符合批量分发，下一次评分跃升即可突破60 → 自动升级为B池 → 触发方案与销售跟进任务。
