- **Day 7 behavior is high-intent, not just high-interest** — a callback request from the success team signals active buying motion and hands the sales team a warm, consented conversation window, which is far stronger than passive content views. 第7天的行为是“高意向”而非仅仅“高兴趣”——主动要求成功团队回电，说明客户已进入主动购买阶段，为销售创造了有授权、有温度的沟通窗口，价值远超被动浏览内容。 - **Score math keeps it in C Pool by design** — 20 → 24 (+4 from the callback) stays well below the 60 C→B threshold, so the AI is correctly protecting sales capacity: one strong signal doesn't yet justify pool upgrade or proposal spend. 评分数理决定其仍留在C池——20→24（回电仅+4），远低于C→B的60分阈值，AI在合理保护销售资源：单一强信号尚不足以触发升级或提案投入。 - **Trigger precise, low-cost actions now** — route the callback request to the success team with the lead's full behavior history, set a follow-up task with a defined SLA, and send a lightweight value asset (case study / training ROI brief) to keep momentum without over-investing. 立即触发精准低成本动作——将回电请求连同完整行为轨迹转交成功团队，设定带明确SLA的跟进任务，并发送轻量价值内容（案例/培训ROI简报）维持势能，避免过度投入。 - **Upgrade path is behavior-sequenced** — if the callback converts into a discovery call or proposal request, cumulative score approaches 60 and the system upgrades C→B, unlocking the B2B proposal and structured sales follow-up workflow. 升级路径按行为序列设计——若回电转化为需求诊断会或提案请求，累计分数逼近60，系统即升级C→B，解锁B2B提案与结构化销售跟进流程。 - **This is the right on-ramp to a 100-unit inquiry** — callback → discovery → proposal is the proven path for volume deals; early, disciplined nurturing preserves deal size and shortens the cycle instead of pressing for a 100-unit commitment prematurely. 这是通向100单元询单的正确入口——回电→需求诊断→提案是批量成交的成熟路径；早期克制的培育既能保住订单规模，也能缩短周期，避免过早施压100单元承诺。
