- **Day 7 request for a callback is high-intent, but not yet high-fit.** It signals active buying interest, yet one action alone doesn’t prove budget, authority, or scale. **第7天主动请求回电，说明购买意向明显，但还不足以证明预算、决策权和采购规模。** - **AI keeps the lead in C Pool because the predicted score is only 11 vs. an upgrade threshold of 60.** The model weights cumulative and repeated high-value behaviors; a single callback request is not enough to trigger C → B. **AI仍放在C池，是因为预测分只有11，远低于60的升级线；模型看的是累计和重复高价值行为，单次回电不够触发C→B。** - **Trigger a low-risk, high-speed sales response, not a full B2B proposal yet.** Assign a success-team callback within 24 hours, confirm training need, learner volume, timeline, and budget owner. **应触发低风险、快速响应的销售动作，而不是立刻发完整B2B方案：24小时内由成功团队回电，确认培训需求、学员规模、时间表和预算负责人。** - **If the callback validates distribution potential, trigger the B2B proposal and sales follow-up task.** Capture whether this is a 100-unit distribution inquiry; if yes, route to A/B nurture logic and create a proposal task. **若回电确认有分销潜力，再触发B2B方案和销售跟进任务；确认是否为100套分销询盘，若是则转入A/B培育逻辑并创建提案任务。** - **Business outcome:** This prevents premature upgrade while protecting a high-intent lead, improving pipeline quality and increasing the chance of converting into a 100-unit distribution deal. **业务结果：避免过早升级，同时保护高意向线索，提升管道质量，并提高转化为100套分销订单的概率。**
