- **Day 7 callback request = high intent, not just interest.** Asking for a human contact signals buying readiness and a real problem to solve—far stronger than passive views or content watches. 中文：主动要求回电代表真实购买意向和明确需求，远强于浏览或看视频这类被动行为。 - **Score moved 0 → 3, but 3 << 60 threshold.** The behavior is valuable in *kind*, yet a single signal isn't enough *volume* to justify C → B upgrade; AI avoids over-reacting to one event. 中文：分数从0升到3，但离60的升级线还很远——行为类型有价值，但单一信号不足以支撑升级，AI避免过度反应。 - **Pool stays C; no proposal or B-level task yet.** Keep nurture light: log the callback request, assign a success-team rep, and schedule a discovery call within 24–48h. 中文：仍留在C池，暂不触发方案或B级任务；先记录回电请求、指派成功团队跟进、48小时内安排需求沟通。 - **Trigger precise micro-actions, not a full B2B proposal.** Confirm callback, qualify training scope (audience, units, timeline), and tag the lead as "callback-requested" to weight future scoring. 中文：触发精准的小动作而非完整方案——确认回电、摸清培训范围（人数、单元、时间），并打上"已请求回电"标签以加权后续评分。 - **Path to a 100-unit distribution inquiry:** discovery call surfaces volume need → qualification validates 100 units → AI score jumps, crosses 60, upgrades to B → proposal + sales follow-up fire → pipeline quality and deal size rise. 中文：通往100单元分销询盘的路径：需求沟通发现批量需求→资格确认100单元→AI分数跃升过60升级B池→触发方案与销售跟进→提升管道质量与成交规模。
