- **High-value behavior:** Repeated high-intent engagement on Day 7 signals active buying interest — a strong pipeline quality indicator, not passive browsing. 重复的高意向互动说明客户在主动评估，购买信号明显强于普通浏览，是高质量商机的早期标志。 - **Why still C Pool:** Predicted score of 34 sits well below the C→B threshold of 60, so AI correctly withholds upgrade — avoiding premature sales cost and quota waste. 预测分34仍远低于升级门槛60，AI不升级是合理的，避免过早投入销售资源、浪费团队产能。 - **Precise triggered actions:** Flag account for priority monitoring, send a tailored B2B proposal with volume-tier pricing, and create a sales follow-up task within 48 hours. 应触发：标记为重点监控账户、发送含批量阶梯报价的定制方案、48小时内生成销售跟进任务。 - **Logic chain:** Behavior → score lift (30→34) → no pool upgrade → light-touch nurture with targeted proposal → keeps deal warm at low cost. 行为→分数提升（30→34）→不升级→低成本精准培育+定向方案→以更低成本维持商机热度。 - **100-unit inquiry path:** Sustained engagement plus a volume-oriented proposal pre-qualifies budget and scale, shortening the sales cycle once score crosses 60 into B Pool. 持续互动叠加批量导向的方案，可提前验证预算与规模，一旦分数突破60进入B池，将显著缩短成单周期。
