**Day 7 High-Value Signal → C→B Upgrade → 100-Unit Inquiry Path** - **Why "clicked contact info" is high-value:** It's an explicit intent signal — the buyer moves from passive content consumption to actively seeking a human contact, a strong late-funnel indicator. 点击联系方式是高意向信号：客户从被动浏览转为主动寻求对接，属于漏斗后端的强购买意图。 - **Why C→B upgrade:** Score jumped from 57 to a predicted 88, clearing the 60 threshold — the AI reads the acceleration (not just the absolute score) as rising deal potential. 分数从57跃升至预测88，突破60阈值；AI看重的是增速而非单点分数，判定商机潜力上升。 - **Precise actions to trigger:** Send a tailored B2B proposal (100-unit volume pricing) + create a sales follow-up task within 24h + route to an assigned rep. 系统应触发：定制化B2B方案（含100套批量报价）、24小时内销售跟进任务、分配专属销售。 - **Why it supports the 100-unit inquiry:** Volume-relevant proposal timing + fast human follow-up converts intent into a qualified distribution conversation while interest is peak. 批量方案与快速人工跟进在兴趣峰值时把意图转化为合格的经销洽谈，直接支撑100套询盘。 - **Business impact:** Higher pipeline quality, shorter response lag, and better sales efficiency — the score-to-action loop protects conversion rate on your best-fit leads. 业务价值：提升管道质量、缩短响应时差、提高销售效率，用"评分→动作"闭环守住高匹配线索的转化率。 Note: 88 < 120 (A threshold) — keep in B pool; next upgrade trigger is repeat high-value behavior or proposal engagement. 注：88未达120（A池阈值），暂留B池；下次升级看重复高价值行为或方案互动。
