1. **High-Value Behavior Logic** Requesting a callback from the success team signals strong purchase intent—it’s a top-decision action, not passive content consumption. **高价值行为逻辑**：主动要求销售跟进的用户，表明明确的购买意向，远超普通内容浏览行为。 2. **AI Upgrade Rationale (C → B)** Score jumped from 20 to 55 by Day 6, then to 77 after callback. Crossing the 60 threshold triggers AI upgrade, reflecting sustained engagement + high-intent signal. **AI升级原因**：分数从20升至55，再因“请求回电”冲至77分，跨越60阈值，表明持续互动和强购买信号。 3. **Triggered Nurturing Actions** - Immediate: Assign sales rep to callback within 2 hours - Automated: Send tailored B2B proposal (e.g., enterprise skill gap audit) - Follow-up: Add to "fast-track" CRM sequence for contract discussion **自动触发动作**：2小时内分配销售回电，发送定制化企业培训方案，并进入“加速转化”CRM流程。 4. **Path to 100-Unit Inquiry** B2B proposal targets distribution-level deal (100-unit training seats). The callback + proposal directly addresses scalability needs, moving from awareness to negotiation. **通往百单询盘路径**：定制化方案直接匹配渠道级培训采购量（100席位），从意向转化为商务谈判。
