**Day 7 Nurturing Readout — Global Skills** - **Behavior is high-intent, not high-volume.** Clicking contact info signals active vendor evaluation — a deliberate step toward a sales conversation, worth more than content views or video watches. 点击联系方式是明确的采购意向信号，代表客户已进入供应商评估阶段，价值远高于浏览或看视频。 - **Score still short of the C→B gate.** Day 7 predicted score of 25 vs. a 60 threshold: the AI upgrades on cumulative evidence (repeat interactions, proposal engagement), not a single click. C Pool is correct — the signal is early, not yet qualified. 预测分25分，远低于C升B的60分门槛。AI依据累计行为升级，单次点击不足以晋级，留在C池是合理的。 - **Trigger lightweight, score-building actions — not a full proposal yet.** Send a targeted training-catalog/overview + short case study, auto-log a sales follow-up task with a 48-hour SLA, and enroll the lead in an intent-scoring email sequence. Hold the formal B2B proposal until B Pool. 现阶段应触发轻量培育：推送定向课程目录与案例、自动生成48小时跟进的销售任务、加入意向打分邮件序列；正式B2B方案留到B池再发。 - **Protect the 100-unit inquiry with qualification, not pressure.** Use the follow-up call to confirm volume, timeline, and decision-makers; a 100-unit distribution inquiry is high-value — verify fit before committing proposal resources. 用跟进电话确认采购规模、时间表与决策人；100套分销询盘价值高，应先验证需求再投入方案资源。 - **Pipeline logic:** early intent → modest score gain (+5) → stay in C → nurture and observe → escalate to B when engagement compounds, preserving sales efficiency on the highest-value deals. 行为→小幅加分(+5)→留在C池→培育观察→互动累积后升级B池，把销售资源集中在最有价值的商机上。
