Here's the read on this lead: - **Day 7 behavior signals buying intent, not browsing.** A callback request from the success team is an explicit, human-initiated commitment—far stronger than views or video watches, which only indicate interest. - 第七天主动预约成功团队回电，代表的不只是兴趣，而是明确的购买意向——比浏览页面、看视频强得多。 - **Score stayed in C because one strong signal ≠ threshold.** At 22 vs. the C→B threshold of 60, the AI is weighing cumulative evidence; a single high-value action lifts momentum but not enough to justify a pool upgrade (and premature B-level sales effort). - 评分22，远低于升级门槛60。单次高价值行为提升了动能，但不足以触发升级，避免过早投入B级销售资源。 - **Trigger precise, low-cost actions now.** Route to success team for the callback (within 24h), log the request as a follow-up task, and send a tailored capability deck—not a full proposal yet. - 立即安排成功团队24小时内回电，创建跟进任务，并发送定制化能力介绍，暂不启动完整提案。 - **Nurture toward the 100-unit inquiry.** Use the callback to qualify scope (cohort size, timeline, budget owner); if signals confirm, fast-track score and trigger a B2B proposal + sales follow-up. - 借回电摸清采购规模、时间线和决策人；若信号确认，快速提分并触发B2B提案与销售跟进，推动100套分销询盘落地。 - **Business outcome:** converting this behavior into a qualified callback protects sales efficiency while positioning a large-volume deal for the pipeline. - 把这次行为转化为有效回访，既保护销售效率，又为大单进入管道铺路。
