- **Day 7 behavior signals buying intent, not just browsing.** A callback request from the success team is a self-initiated, human-contact ask — the strongest pre-pipeline signal in B2B training sales. - 中文：第7天的“请求成功团队回电”是客户主动发起的人工接触，属于购前最强的意向信号，远高于浏览或看视频。 - **AI score only moves 10 → 11 because one signal isn't enough to cross 60.** Score models weigh cumulative evidence (repeat visits, proposal views, video completion); a single high-value action nudges, not jumps. - 中文：分数只从10升到11，是因为单次行为不足以越过60分阈值；AI看重累积证据（反复访问、方案查看、视频完播），一次高价值动作只是加分，不是跃迁。 - **Stays in C Pool = correct risk control.** Upgrading on one callback request would flood B Pool with unqualified leads and cut sales efficiency; the threshold protects pipeline quality. - 中文：留在C池是合理的风控：仅凭一次回电请求就升级，会让B池充斥未合格线索、拉低销售效率；阈值机制正是为了保护管道质量。 - **Trigger precise, low-cost nurturing now.** Route the callback to the success team within SLA, log it as a sales follow-up task, and send a tailored enterprise-training proposal + case study — no full A-level sales motion yet. - 中文：立即触发精准低成本培育：在SLA内把回电转给成功团队、登记为销售跟进任务，并发送定制化企业培训方案与案例——暂不启动A级完整销售动作。 - **This sets up the 100-unit distribution inquiry.** A handled callback plus a relevant proposal builds trust and surfaces volume needs; continued engagement then pushes score toward 60, triggering C→B upgrade and a formal sales handoff. - 中文：这为100单元分销询盘铺路：及时回电+对口方案建立信任并挖出批量需求；后续互动把分数推向60，触发C→B升级和正式销售交接。
