- **Callback request = active buying signal.** A prospect who asks to speak to the success team has self-identified as sales-ready; intent is explicit, not inferred. 主动要求回访是明确的购买信号——客户已主动表明意向，销售无需再猜测。 - **Score +7 reflects quality, not scale.** The behavior lifts the AI score from 0 to 7, but it sits far below the 60 C→B threshold — one strong signal can't override a thin behavioral history. 行为加7分体现的是质量而非体量——单次高价值动作不足以跨越60分升级线。 - **Stay in C Pool, but flag for human review.** No automated upgrade or proposal trigger fires; instead, the system alerts the sales team to validate the inquiry size (100 units) before re-scoring. 客户暂留C池但进入人工复核——系统不自动发提案，先由销售核实100套的采购规模再重新评分。 - **Trigger precise, low-cost actions.** Route the callback to the success team within 24h, log call notes to enrich the profile, and schedule a follow-up task — actions that build score without over-investing. 触发低成本精准动作——24小时内转接成功团队、记录通话补充画像、创建跟进任务，稳步积累分数。 - **Path to 100-unit conversion.** A validated callback plus proposal/quote and consistent follow-up can add 50+ points, pushing the lead into B Pool and unlocking proposal automation — turning intent into pipeline. 通向100套成交的路径——回访确认+提案报价+持续跟进可再叠加50分以上，推动升级至B池并触发提案自动化，把意向转化为商机。
