- **Day 7 behavior = buying signal, not casual browsing.** Clicking contact info shows active intent to reach a human; it's a strong decision-stage cue, so AI weights it above generic content views. 中文：Day 7 点击联系方式是明确的购买信号，比普通浏览更有价值，因为客户开始主动寻找对接人。 - **Score did move, but 31 < 60 threshold.** The behavior added only +1 to the predicted score (30→31) because cumulative engagement is still thin; AI is cautious, not dismissive. 中文：分数确实上升（30→31），但远低于 60 的升级门槛，AI 判断互动深度还不够，暂不升级。 - **Stay in C Pool = controlled investment.** No sales proposal or human follow-up yet; the system avoids wasting sales capacity on premature leads. 中文：留在 C 池意味着暂不投入销售资源，避免在需求未成熟时浪费人力。 - **Trigger low-cost nurturing, not sales tasks.** Send a personalized content email (e.g., case study / training ROI one-pager), offer a self-serve resource, and set a re-score check in 3–5 days; escalate to B only when threshold is crossed. 中文：触发低成本培育动作，如发送定制化案例或 ROI 资料、提供自助资源，并设置 3–5 天后重新评分；达到门槛再升级 B 池。 - **Path to the 100-unit inquiry: build evidence before contact.** Use these touches to establish need and budget signals; once score hits 60 and upgrades to B, trigger proposal + sales follow-up—turning a single contact click into a qualified 100-unit distribution conversation. 中文：先通过培育积累需求与预算信号；达到 60 分升级 B 池后，再触发方案与销售跟进，把一次联系方式点击转化为 100 套分销询盘。
