- **Day 7 callback request = explicit buying intent.** A prospect asking the success team to call is a self-qualified signal — it shortens the trust-building cycle and de-risks outreach, unlike passive views or video watches. 第7天主动要求回电是明确的购买意向，属于客户自我筛选的高价值信号，能显著缩短信任建立周期，比单纯的浏览或看视频更有价值。 - **Score 22 vs. threshold 60: intent is high, qualification is not.** The AI keeps the lead in C Pool because cumulative engagement (20) plus this single spike (+2) still falls far below the C→B bar — one strong signal doesn't override thin behavioral history. 分数22远低于60的升级门槛：意向强但资质不足，单次高价值行为无法替代累计行为深度，因此AI仍将其保留在C池。 - **Trigger precise, low-cost actions — not a full B2B proposal yet.** System should auto-create a sales follow-up task with a 24-hour SLA, route to the success team with context (behavior + score), and send a tailored capability deck or training-needs checklist. 触发精准低成本动作而非完整方案：自动生成24小时内完成的销售跟进任务，将行为与分数上下文转交成功团队，并发送定制能力介绍或培训需求清单。 - **Use the callback to qualify the 100-unit distribution inquiry.** The call should confirm budget, decision-makers, timeline, and distribution scope — feeding structured data back to raise the score toward 60 and justify C→B upgrade. 借回电核实100套分销询盘的预算、决策人、时间表和分销范围，将结构化信息回填系统以推高分数至60，支撑C→B升级。 - **Business outcome: protect pipeline quality and sales efficiency.** Gating the upgrade prevents premature proposal effort on unqualified leads, while the SLA-bound follow-up keeps a high-intent lead warm — improving conversion rate on the eventual 100-unit deal. 业务结果：门槛控制避免在未资质客户上过早投入方案资源，SLA跟进保持高意向客户热度，从而提升100套大单的转化率与销售效率。
