**Lead: C → B upgrade driven by Day 7 high-intent behavior** - **Day 7 "clicked contact info" = purchase-intent signal, not passive browsing.** This is an action step toward direct engagement; it typically precedes a distribution/scoping conversation. - 第7天“点击联系方式”属于主动意图信号，而非普通浏览，通常意味着客户准备进入实质沟通。 - **Score jump 57 → 88 crosses the 60 threshold, so AI auto-upgrades C → B.** The model weights contact-click heavily because it correlates with higher conversion and larger deal size. - 分数从57跃升至88，跨过60阈值，系统自动将客户从C池升级至B池；点击联系方式与更高转化率和大单概率强相关。 - **Triggered actions: send B2B proposal + create sales follow-up task (with SLA).** Move from marketing nurture to sales-assisted motion; assign owner and set a 24–48h follow-up. - 触发动作：发送B2B方案并创建销售跟进任务（含时效要求），从市场培育切换为销售协同推进。 - **This behavior predicts a 100-unit distribution inquiry, so route to enterprise/distribution playbook.** Give the rep volume-pricing, licensing, and rollout materials instead of generic content. - 该行为预示100套分销询盘，应切换到企业/分销话术，提供批量报价、授权与落地资料，而非通用内容。 - **Still 32 points from B → A (120): keep nurturing while sales works the deal.** Track proposal opens, meeting bookings, and stakeholder invites to decide when to escalate to A. - 距离B升A（120分）还差32分：销售推进的同时持续培育，用方案打开、会议预约、决策人引入等信号决定是否升级到A池。
