- **Day 7 callback request = explicit buying intent, not passive interest.** A direct conversation ask from the success team is one of the strongest first-party signals of readiness — far above page views or video watches. - 客户主动要求回电，是明确的购买意向信号，比浏览页面或看视频的"被动兴趣"价值高得多。 - **AI stays in C Pool because a single signal ≠ qualification.** Score of 2 vs. threshold 60: low frequency, no repeat engagement, and no firmographic fit confirmed yet. One request alone doesn't justify a pool upgrade. - 仍留在C池是因为单一信号不等于合格线索：2分远低于60分阈值，互动频率低、无复访、企业画像未确认，不足以升级。 - **Trigger precise, low-cost nurturing actions, not a full sales push.** Route the callback to the success team (SLA: same-day), log the request as a tracked task, and send a lightweight needs-discovery brief — hold the B2B proposal until fit is confirmed. - 触发精准的低成本培育动作：当日转交成功团队（SLA当天）、登记跟进任务、发送轻量需求调研简报；在确认匹配前暂不发正式方案。 - **Callback is the fastest path to firmographic data.** Use the call to capture unit volume, budget, decision timeline — this data feeds the AI score and accelerates the eventual C → B upgrade. - 回电是获取企业画像的最快方式：通过通话确认采购量、预算、决策周期，这些数据反哺AI评分，加速后续C→B升级。 - **Route toward the 100-unit inquiry without premature upselling.** Confirmed 100-unit intent should re-score the lead sharply, triggering proposal + pool upgrade in one motion — keeping the pipeline clean and sales effort proportionate. - 在不提前推销的前提下引导至100套采购咨询：一旦确认100套意向，应立即重算评分，同步触发方案发送与泳道升级，保证管道质量与销售投入匹配。
