- **Day 7 behavior = active buying signal, not passive content consumption.** Requesting a callback shifts the lead from "interest" to "intent," with a named success team as the entry point. **中文：** 第7天的行为是主动购买信号，而非被动内容浏览。要求回电说明客户已从“感兴趣”转向“有意图”，并直接对接成功团队。 - **Score stays at 22 vs. 60 threshold because one high-value action can't override weak cumulative engagement.** The AI weights behavior quality plus consistency; Days 1–6 only produced 20 points, so C Pool remains the correct risk-managed stage. **中文：** 评分22分，未达60分升级线，因为单次高价值行为无法抵消累计互动不足。AI同时看行为质量和持续度，前6天仅20分，留在C池是合理的风险控制。 - **Trigger structured but lightweight follow-up — not a full B2B proposal yet.** Actions: assign a success-team callback within 24h, send a tailored training overview + ROI one-pager, and log a sales task to qualify budget, timeline, and distribution scale. **中文：** 触发结构化但轻量的跟进，而非直接发送完整B2B方案。动作包括：24小时内安排成功团队回电、发送定制培训概览和ROI单页、创建销售任务以确认预算、时间表和分销规模。 - **This moves the lead toward a qualified 100-unit distribution inquiry by testing seriousness first.** The callback confirms real need; if the prospect engages (e.g., asks about volume pricing, pilot, or rollout), score accelerates and C→B upgrade triggers proposal generation. **中文：** 先验证客户严肃程度，再推进至100套分销询盘。回电确认真实需求；若客户继续互动（如询问批量价格、试点或推广计划），评分加速上升，触发C→B升级并自动生成方案。 - **Business outcome:** Higher pipeline quality, shorter sales cycle for bulk deals, and sales effort focused only on leads that show intent + engagement. **中文：** 业务结果：提升管道质量、缩短批量订单销售周期，并让销售精力集中在“有意图+有互动”的线索上。
