- **Callback request = active buying signal.** The lead stopped browsing and asked for human contact—stronger than passive views or video watches. 客户主动约回调，说明已从“看内容”进入“要方案”的采购阶段。 - **Score jumped to 77, crossing the C→B threshold (60).** AI rewards intent-linked actions, so the system upgrades from C to B; B→A still needs 120. Day 7 行为把分数推到 77，越过 C→B 的 60 分门槛，因此升级到 B 池；距离 B→A 的 120 分还有差距。 - **Trigger precise B2B nurturing, not mass marketing.** Route to success team for callback, create sales follow-up task, and prepare a tailored proposal / training distribution deck. 触发精准动作：分配给成功团队回访、创建销售跟进任务、准备定制化提案与培训分销方案。 - **This raises pipeline quality and sales efficiency.** B-pool leads get higher-touch follow-up, better meeting-to-opportunity conversion, and shorter sales cycles. 这提升商机质量与销售效率：B 池客户获得更高触达，会议转商机率更高，销售周期更短。 - **Path to a 100-unit distribution inquiry.** The callback lets sales qualify volume, budget, and timeline; the AI then keeps scoring engagement until it hits A-pool and escalates to enterprise deal motion. 通向 100 套分销询盘：回访中确认采购量、预算与时间表，AI 继续累积互动分，达 A 池后升级为企业级成交推动。
