- **Day 7 callback request = high intent, not just interest.** It signals the lead wants human contact now, which historically correlates with faster progression and larger deal potential. 该行为说明客户不只是浏览，而是主动要求人工沟通，购买意向明显更强，通常更接近商机阶段。 - **Score jumps 0 → 6, but stays below the C→B threshold of 60.** This is a meaningful signal, not enough evidence to reclassify; AI avoids premature pool upgrades. 分数从0升到6，虽显示兴趣上升，但远低于60的升级门槛，因此暂不升级，避免误判。 - **Keep in C Pool, but flag as high-priority follow-up.** The system should trigger a success-team callback task and sales follow-up within SLA, plus send a tailored B2B training proposal. 客户仍留在C池，但应标记为优先跟进，触发成功团队回电、销售跟进，并发送定制化B2B培训方案。 - **Nurture toward a 100-unit distribution inquiry.** Use the callback to qualify seats, delivery model, and budget; then route to sales for a proposal aligned to 100-unit rollout. 通过回电确认人数、交付方式和预算，再转销售输出100单位分销方案，推动商机升级。
