**1) Why "requested callback" is high value** - It's a self-declared buying signal: the lead is actively asking for human contact, which is far stronger than passive content views. - 中文：主动要求回电是明确的购买意向信号，远比被动浏览内容更有价值。 **2) Why AI keeps this lead in C Pool** - One strong signal isn't enough: predicted score of 13 vs. threshold of 60, and cumulative history (Days 1–6) shows low engagement. - 中文：单次强信号不足以升级——预测分13远低于60的门槛，且前6天累计互动偏低。 **3) Precise nurturing actions to trigger** - Assign a success-team callback task within 24h (SLA-bound), tag the lead as "inbound request," and queue a lightweight capability deck — hold the full B2B proposal until budget/scope signals appear. - 中文：24小时内派发成功团队回电任务（设SLA），标记为"主动咨询"，先发轻量能力介绍——待预算/范围信号明确后再出正式方案。 **4) Path to the 100-unit distribution inquiry** - Use the callback to qualify headcount, timeline, and budget; each confirmed data point raises the score toward the 60 threshold, triggering C→B upgrade and a formal proposal — the natural entry to a 100-seat distribution deal. - 中文：通过回电确认人数、时间表和预算；每项确认都会推高分数至60门槛，触发C→B升级和正式提案——这是通向100人分销订单的入口。 **Business impact:** faster response on inbound signals protects pipeline quality and shortens the C→B→proposal cycle without over-investing sales time in low-score leads. 中文：对主动信号快速响应可保障管道质量，并在不浪费销售资源的前提下缩短C→B→提案的周期。
