**Day 7 Nurturing Read — High-Value Behavior, Still C Pool** - **Why it's high value:** Completing a post-video survey is active intent, not passive viewing — it signals the buyer is engaged enough to invest time and share context (needs, priorities, evaluation criteria). That's strong qualification data for training solutions. 这是主动意向信号，而非被动观看；愿意花时间填写问卷说明其在认真评估培训方案，并提供了需求与优先级的宝贵信息，资格判断价值高。 - **Why still C (no upgrade):** Predicted score 29 vs. C→B threshold 60 — the behavior lifts momentum (+9 vs. prior 20) but is not yet sufficient alone. Single-questionnaire engagement ≠ buying committee readiness; AI waits for compounding signals. 预测分29，距升级线60仍有差距；问卷是加分项但不足以单独触发升级，AI在等待更多叠加信号（如方案查看、多人参与）。 - **Triggered actions (precise, low-cost):** Send a tailored capability deck / light proposal aligned to survey answers; enroll in a 2-touch email nurture (case study + ROI one-pager); log a soft follow-up task for the SDR in 5–7 days — not a hard sales push yet. 触发动作：按问卷内容发送定制能力介绍/轻量方案；进入两步邮件培育（案例+ROI简表）；为销售创建5–7天后的软跟进任务，暂不做强推。 - **Path to 100-unit inquiry:** Each qualifying touch should nudge score toward 60; crossing it upgrades C→B and auto-triggers a formal proposal + sales follow-up. Sustained engagement then justifies scoping a 100-seat distribution/training rollout conversation. 通往100套询盘：每次有效触达推动分数逼近60，越线后自动升级并触发正式方案与销售跟进，持续互动即可自然引导至100套分销/培训落地的商务讨论。 - **Business logic:** Behavior → score (+9) → no pool change yet → targeted nurture → higher-conversion B-stage handoff. This protects sales capacity by reserving human follow-up for genuinely sales-ready leads. 业务逻辑：行为→加分→暂不换池→精准培育→更高转化的B阶段交接；把人工跟进留给真正就绪的线索，提升销售效率。
