**Day 7 nurture readout — Global Skills (C Pool, score 24 vs. C→B threshold 60)** - **Callback request = buying signal, not browsing.** Asking for a success-team callback shows intent to discuss outcomes and budget; it converts anonymous interest into a named, sales-ready contact. - 主动要求成功团队回电，说明客户已从“看内容”进入“谈结果和预算”阶段，是高意向信号。 - **Score jump is real but not enough to upgrade.** Day 7 moves the lead from 20 → 24 (+4); the behavior is valuable, but a single action can't bridge the 36-point gap to 60. AI weights cumulative, multi-touch evidence, so the lead stays in C for now. - 单次高价值行为带来 +4 分，仍距 60 分阈值差 36 分；AI 看重累计多触点证据，因此暂不升级。 - **Trigger precise, low-cost nurturing — not a full proposal yet.** Route to success team for the callback within 24h, log call notes, send a tailored capability deck plus a short case study, and set a follow-up task in 3–5 days. - 24 小时内安排成功团队回电并记录要点，发送定制能力介绍+短案例，3–5 天后设置跟进任务；暂不启动正式方案。 - **Qualify the 100-unit ask during the call.** Confirm seat/unit volume, timeline, decision-makers and budget range; capture these as structured fields so they feed the score. - 通话中确认 100 人规模、时间表、决策人和预算区间，并结构化录入系统反哺评分。 - **Upgrade path to B.** If the callback yields verified volume + timeline, expected score gain pushes toward 60, triggering C→B upgrade and a formal B2B proposal; this protects sales time and keeps pipeline quality high. - 若回电确认规模与时间表，分数将逼近 60，触发 C→B 升级并生成正式方案，从而提升转化率与销售效率。
