- **Day 7 callback request = active buying intent, not passive content consumption.** A lead asking to speak with the success team moves from research to evaluation—the strongest pre-purchase signal we track. - 第7天主动申请回电是明确的购买意向，而非被动浏览；客户从"了解"进入"评估"阶段，是最强的购前信号。 - **Score rose sharply (32 → 41, +9 in one event) but stays below the 60 C→B threshold.** The AI recognizes momentum without over-weighting a single touch. Pool logic is threshold-based, so upgrade waits until cumulative evidence justifies it. - 单次行为带来9分跃升，说明动能强劲，但仍低于60分的C→B门槛；AI只按累计证据升级，不会因单次互动过度加权。 - **Trigger now: fast callback within 24h, log a sales follow-up task, and send a tailored B2B proposal + success-team case study.** No pool change yet, but high-touch nurture begins—treat it as a hot C lead. - 立即触发：24小时内回电、生成销售跟进任务、发送定制B2B方案与成功案例；虽不升级，但按"热线索"高接触培育。 - **The 100-unit distribution inquiry needs volume-tiered proof.** Arm the success team with pricing tiers, volume-discount logic, and a distribution-reference case so the callback converts intent into a qualified opportunity. - 100单位的批量采购询盘需要"阶梯报价+批量折扣+分销案例"支撑，让回电直接转化为合格商机。 - **Business outcome: pipeline quality up, sales efficiency up.** Score-based triggers ensure reps spend time on genuinely warm leads—improving conversion rate on C-pool and shortening the path to a large distribution deal. - 业务结果：管道质量提升、销售效率提高；按分数触发行动让销售聚焦真实热线索，提升C池转化率并缩短大额分销订单的成交周期。
