- **Why it's high value:** A callback request is an explicit buying signal—the lead is inviting sales contact, which typically lifts engagement and shortens the consideration cycle. 这是明确的高意向信号：客户主动要求联系，说明愿意推进沟通，通常会加快决策节奏。 - **Why it stays in C Pool:** Score moves only 10 → 13, far below the 60 threshold; one strong signal doesn't offset low cumulative engagement (Days 1–6 flat at 10). 分数仅从10升到13，远低于60的升级线；单次高价值行为不足以弥补前期互动偏低。 - **Triggered actions:** Route a success-team callback within SLA, log call notes, and auto-create a follow-up task; send a lightweight capability deck rather than a full proposal. 在SLA内安排成功团队回电、记录通话要点并自动生成跟进任务；先发精简能力介绍，而非完整方案。 - **Path to the 100-unit inquiry:** Use the callback to confirm cohort size, budget and timeline; if confirmed, fast-track a tailored B2B proposal and re-score—likely crossing into B pool and triggering formal sales follow-up. 通过回电确认人数、预算与时间表；若确认，快速出具定制化B2B方案并重新评分，有望进入B池并触发正式销售跟进。
