**Day 7 Callback Request — Readout (Lead Stayed in C Pool)** - **High-value signal, but a single touch.** Requesting a callback is an explicit hand-raise: intent, urgency and a named contact preference. It's high value because it converts passive browsing into a direct sales conversation route — but one action alone carries limited weight. - 主动约回电是明确的意向信号，代表紧迫性和真实接触意愿；但它只是单次行为，权重有限。 - **Score math keeps it in C.** Day 7 score = 3, far below the C→B threshold of 60. Cumulative behavior (Days 1–6) was zero, so there is no pattern of engagement to justify a pool upgrade yet. - 第7天得分仅3分，远低于C→B的60分门槛；前6天零互动，缺乏可支撑升级的行为轨迹。 - **Trigger immediate, low-friction sales follow-up.** Route to the success team for a scheduled callback within 24h; log call notes and set a follow-up task. Hold the formal B2B proposal until qualification confirms scope. - 24小时内由成功团队回电并记录要点、创建跟进任务；正式B2B方案暂缓，待确认需求范围后再发。 - **Qualify the 100-unit distribution inquiry.** Use the callback to confirm unit volume, delivery timeline, budget owner and decision process — this is where a 100-unit deal is validated or re-scoped. - 回电中核实100套的分销规模、交付时间、预算归属与决策链，据此判断大单可行性。 - **Watch for the upgrade path.** A second high-value action (proposal request, pricing inquiry, repeat visit) should push the score toward 60 and auto-upgrade C→B, unlocking proposal and pipeline acceleration. - 若出现第二次高价值行为（索要方案、询价、复访），分数将逼近60并自动升级至B池，触发方案推送与商机加速。
