- **Day 7 callback request = buying-signal, not browsing.** It shows intent to talk to a human about outcomes and budget, so AI weights it heavily (+8 points, 32→40). - 第七天主动约回电，是明确的购买信号，不只是浏览行为，因此 AI 大幅加分（32→40）。 - **Still in C Pool because score (40) < C→B threshold (60).** One strong signal isn't enough; AI waits for cumulative proof (repeat high-value actions, content depth) before upgrading. - 仍留在 C 池是因为 40 分未达 60 分升级线；单次强信号不足以升级，需累计高价值行为佐证。 - **Trigger now: route callback to success team within SLA, prep a tailored 100-unit distribution proposal outline, and log a sales follow-up task.** Keep nurture cadence active in C Pool. - 立即触发：按 SLA 将回电转交成功团队，准备 100 套分销方案要点，并创建销售跟进任务；C 池培育节奏保持。 - **Next-score path:** another high-value action (proposal review, demo, multi-stakeholder view) pushes score past 60 → C→B upgrade → proposal sent + deal task created. - 下一步路径：再出现一次高价值行为（方案评审、演示、多人查看）即可越过 60 分，触发 C→B 升级，自动发方案并建商机任务。 - **Business outcome:** faster response to a warm 100-unit inquiry, cleaner pipeline quality, and higher conversion efficiency without over-investing sales time on unqualified leads. - 业务结果：更快响应 100 套分销意向，提升管道质量与转化效率，同时避免销售资源浪费在未合格线索上。
