- **Day 7 behavior signals active buying intent, not passive browsing.** A callback request puts the lead in direct contact with the success team — that's a sales-ready motion. 第7天的行为代表主动购买意向，而非被动浏览；主动约回电意味着已进入销售可直接推进的阶段。 - **Score stays in C Pool because 53 < 60 threshold.** The behavior is strong but cumulative evidence (45 before Day 7) is still building; AI avoids premature upgrade. 分数53仍低于升级门槛60，因此保留在C池；行为信号强，但前6天累计证据不足，AI避免过早升级。 - **Trigger precise, low-cost nurturing now:** prioritize callback within 24h, send a tailored 100-unit distribution proposal, and log a sales follow-up task with a 7-day review checkpoint. 立即触发精准低成本动作：24小时内优先回电、发送定制化100套分销方案、创建销售跟进任务并设7天复盘节点。 - **Re-score after the callback and proposal engagement.** If they open the proposal or reply, the next behavior should push the score past 60 and auto-upgrade C → B. 回电与方案互动后重新评分；若对方打开方案或回复，下一次行为应推动分数越过60，并自动从C升级到B。 - **This path directly supports the 100-unit distribution inquiry:** early callback + tailored proposal shortens the sales cycle, improves pipeline quality, and raises conversion probability on a larger deal size. 该路径直接支撑100套分销询盘：尽早回电加定制方案可缩短销售周期、提升商机质量，并提高大额订单的成交概率。
