- **Day 7 callback request = active buying signal.** Requesting a callback from the success team shows intent to talk to a human, not just browse—early-stage intent, but genuine. 中文：第7天主动要求回电，说明客户已从“看内容”转向“想沟通”，是真实的早期购买信号，而非单纯浏览。 - **Score stays in C because 13 << 60.** A single intent signal adds only ~3 points; AI needs sustained multi-touch evidence (repeat views, video completion, proposal opens) to cross the B threshold. 中文：13分远低于60分门槛，单次行为只加约3分；AI要的是持续多触点证据，才判定值得升级到B池。 - **Trigger light-touch, qualifying actions—not a full B2B proposal yet.** Route callback to success team within 24h, log call notes, send a short needs-discovery agenda and one case study; no pushy proposal at C stage. 中文：触发轻量、探需型动作——24小时内安排回电、记录通话要点、发送简短需求清单和一个案例；C阶段不急着发正式方案。 - **Use the callback to surface scale and distribution intent.** Probe team size, timelines, and whether the 100-unit distribution inquiry is real; capture decision-makers and budget signals to justify a score jump. 中文：借回电摸清规模与分销意向，确认100套分销询盘的真实性，抓住决策人和预算信号，为后续加分升级提供依据。 - **Business outcome:** structured follow-up turns a 13-point signal into qualified pipeline data—higher conversion efficiency and a defensible path toward the 100-unit deal. 中文：业务结果：结构化跟进把13分的弱信号转成可用的商机数据，提升转化效率，并为100套订单铺出可追踪的路径。
