- **Day 7 callback request = real buying intent, not passive browsing.** It moves a dormant lead from zero engagement to direct sales contact, which is the strongest signal in B2B training sales. - 第7天主动要求回电，说明客户已有明确采购意向，而非单纯浏览内容。这是B2B培训销售中最强的意向信号。 - **AI score rises to 6, but C-to-B threshold is 60 — so no upgrade yet.** One high-value action is directional, not conclusive; the model needs repeat signals or higher-intent behaviors to reclassify. - AI评分虽升至6分，但C升B门槛为60分，因此暂不升级。单次高价值行为只是方向性信号，尚不足以触发分层变更。 - **Keep in C Pool, but trigger immediate human follow-up.** This avoids over-automating a low-score lead while ensuring the callback request isn't lost. - 维持C池，但立即触发人工跟进任务，既避免对低分线索过度自动化，又确保回电请求不被遗漏。 - **Trigger actions: schedule sales callback within 24–48h, send tailored training proposal outline, log call outcome, and set a re-score checkpoint.** These steps test whether the interest is real and scalable. - 触发动作：24–48小时内安排销售回电、发送定制化培训方案大纲、记录通话结果、设置重新评分节点。以此验证意向的真实性与可扩展性。 - **This supports the 100-unit distribution inquiry by qualifying budget, timeline, and decision-maker early.** If the callback confirms volume needs, the lead can jump pools quickly and route to a distribution-focused proposal. - 通过早期确认预算、时间表和决策人，为100套分销询盘铺路。若回电确认批量需求，线索可快速升级并转入分销导向方案。
