**Day 7 Lead Nurturing Read — Global Skills** - **Callback request = buying-stage intent, not passive interest.** Asking for a success-team callback signals active evaluation and a named human contact — a far stronger signal than content views. *请求成功团队回电说明客户已进入主动评估阶段，意向远强于单纯浏览内容。* - **Score logic lifts 10 → 18; still 42 points short of the C→B threshold (60).** AI weights a single high-intent signal, but one behavioral event cannot justify a pool upgrade — the model needs cumulative evidence. *单次高意向行为只把分数从10抬到18，距60分升级线还差42分，AI需要更多累积证据才会升级。* - **Pool stays C by design — upgrade must be earned, not assumed.** This protects sales capacity from over-qualifying; C-pool nurture keeps cadence low-cost until evidence compounds. *客户仍留在C池是刻意设计，避免销售资源被过早占用，等证据充分再升级。* - **Trigger actions now (no proposal yet):** - Success team callback within 24h (scheduled task, owner assigned) - Targeted case study on 100-seat cohort rollouts - Log callback outcome back into scoring model *立即触发：24小时内成功团队回电、推送100人批量培训案例、回写通话结果继续打分。* - **Path to the 100-unit distribution inquiry:** Callback → needs qualification (learner count, timeline, budget) → confirmed 100-seat signal pushes score toward 60 → C→B upgrade → proposal/follow-up tasks fire. *转化路径：回电→资格确认（人数/时间/预算）→确认100人需求推高分数至60→升级B池→触发提案与销售跟进。*
