- **Day 7 behavior = strong buying intent, not just browsing.** A callback request from the success team signals the lead is actively seeking human engagement, making it the highest-value signal in the C-pool data set. 该行为代表明确的采购意向，而非简单浏览；主动要求成功团队回电，是高价值互动信号。 - **Score 13 vs. threshold 60 — upgrade logic stays disciplined.** One high-value action adds incremental points but isn't enough to cross the C→B line; AI avoids premature pool upgrades that would inflate pipeline with unqualified leads. 13 分与 60 分门槛差距明显，单次高价值行为不足以升级；AI 保持严谨，避免虚增管道。 - **Trigger near-term, low-cost actions, not a full B2B proposal yet.** Route to success-team callback with a needs-discovery script (training volume, unit count, timeline), log the interaction, and schedule a 48-hour follow-up. 先触发成功团队回电与需求探查（培训规模、数量、时间表），记录互动并安排 48 小时内跟进，暂不发送完整方案。 - **Escalate only on qualifying signals.** If the callback confirms a 100-unit distribution inquiry, attach an enterprise proposal and re-score — that event should push the lead toward B-pool and sales-owned follow-up. 仅在确认 100 套分销需求后升级：附企业方案并重新评分，推动进入 B 池并由销售接手。 - **Business outcome:** fast, targeted response protects conversion rate on high-intent leads while keeping sales effort proportional to score — improving pipeline quality and sales efficiency. 快速精准响应保护高意向线索转化率，同时让销售投入与评分匹配，提升管道质量与销售效率。
