- **Day 7 callback request = explicit buying signal.** 主动要求回电，是明确的购买信号。 It shows active intent, not passive browsing — the highest-value behavior short of an actual quote request. 主动联系胜过被动浏览，是接近询价前最强的意向行为。 - **Score rises 32 → 40, but stays below the 60 upgrade threshold.** 分数从32升到40，但仍未达到60的升级线。 Single high-value action isn't enough for C → B; AI wants sustained momentum and profile fit. 单次高价值行为不足以升级C→B，AI需要持续热度和画像匹配。 - **Trigger immediate, precise follow-up — not a proposal blast.** 立即触发精准跟进，而不是群发方案。 Route to success-team callback within 24h, log a sales task, and send a tailored training-catalog teaser. 24小时内安排成功团队回电、记录销售任务、发送定制培训目录摘要。 - **Hold pool position, raise cadence.** 维持C池，但提高触达频率。 Keep in C Pool with a 7-day re-score check; if engagement continues, B upgrade is likely. 留在C池并设定7天复评，若互动持续则很可能升级到B。 - **Path to 100-unit distribution inquiry.** 通向100套分销询盘。 Warm callback + consultative discovery on volume/distribution needs converts the signal into a qualified enterprise deal. 通过回电和需求挖掘，将信号转化为合格的企业级商机。
