- **High-value signal, low volume:** A callback request is an explicit buying signal—it shows active interest and shortens discovery, but one action alone can’t outweigh weak cumulative engagement. **高价值信号，但体量不足：** 主动要求回电是明确的购买信号，说明兴趣真实、能缩短销售探需周期；但单次行为不足以抵消整体互动偏弱。 - **Score logic keeps it in C:** Day 7 predicted score is 13 vs. the C→B threshold of 60. The model rewards sustained, multi-touch engagement, not isolated intent spikes. **评分逻辑决定仍在 C 池：** 第7天预测分仅13，远低于 C→B 的60分门槛。AI更看重持续、多渠道互动，而非单次意向高峰。 - **Trigger the right sales motion, not an upgrade:** Route to success/sales for callback within SLA, log call outcome, and send a lightweight needs-discovery follow-up—no full B2B proposal yet. **触发精准销售动作，而非升级：** 按SLA转交成功/销售团队回电，记录通话结果，并发送轻量需求探询跟进；暂不生成完整B2B方案。 - **Nurture toward qualification:** Add targeted content (pricing tiers, bulk licensing, case studies) and set a next-step task; if engagement compounds and score nears 60, auto-upgrade to B. **持续培育直至合格：** 推送针对性内容（价格梯度、批量授权、案例），创建下一步任务；若互动累积、分数接近60，则自动升级至B池。 - **Path to 100-unit distribution inquiry:** Treat callback as the entry point to qualify volume, decision process, and timeline; consistent follow-up raises score, triggering proposal and distribution pricing. **通向100套分销询盘的路径：** 将回电视为资格确认入口，厘清数量、决策流程与时间表；持续跟进攻势提升评分，进而触发方案与分销报价。
