**Day 7 Callback Request: Nurture Logic & Business Impact** - **High-value signal: intent, not just interest.** A callback request is an explicit hand-raise — the lead is asking for human contact. This is far stronger than passive views or video watches, which show curiosity but not buying readiness. - 主动要求回电是明确的高意向信号，不是泛泛的兴趣；相比浏览和看视频，这是更强的购买准备度表现。 - **AI score jump reflects behavior weighting.** Score rose from 54 → 72 (+18) on a single action, crossing the B threshold of 60. The model weights explicit intent actions heavily because they historically correlate with faster conversion. - AI 分数从 54 跃升到 72，单一主动行为加分很高，说明模型对“明确意向”动作赋予了高权重。 - **Pool upgrade C → B changes service level.** Crossing 60 triggers a pool upgrade, shifting the lead from automated nurturing to higher-touch, sales-assisted engagement. - C 池升到 B 池意味着服务升级：从自动化培育转为销售参与的深度跟进。 - **Triggered actions should be precise, not generic.** On the upgrade event, the system should: (1) create a sales follow-up task within 24h, (2) send a tailored B2B proposal, and (3) route the callback to the success team with full behavior history attached. - 升级事件应触发精准动作：24 小时内生成销售跟进任务、推送定制化 B2B 方案、将回电请求连同行为轨迹转交成功团队。 - **Path to the 100-unit deal.** B → A requires 120 points; a booked call plus proposal review typically adds 40–60. Accelerating this lead toward a distribution-scale inquiry shortens the pipeline and raises expected deal size. - 通往 100 套订单的路径清晰：完成回电与方案评审通常可再加 40–60 分；加速此线索进入分销级询盘，可缩短销售周期并提升单笔金额。
