"""App2 财务洞察 · 店长视角评分方法 v2。

围绕"店长读了这 12 条能做什么 / 学到什么"做评估，三大维度：

【1】准确性（客观正确 · 越高越好）
  - 数字取自 payload，无编造
  - 引用权威字段（非原始指标兜底）
  - 遵守业务规则（手动调整不拆明细 / 禁行业数字 / 禁单期推测 / 对比口径）
  - 数据缺失/0 支出主动标注

【2】洞察深度（业务价值 · 越高越好）
  - 非显性信号挖掘（"消耗>充值=存量消费"/"差值=平均让利"等解读）
  - 多指标协同分析（seq 11 结构失衡 + 原因互相印证）
  - 根因而非表象（如"数据录入缺失"而不只"支出为 0"）
  - seq 12 跟踪 4 要素齐全（指标 / 阈值 / 节奏 / 触发动作）
  - 避免空洞表达（"关注 XX" / "加强 XX" 被扣分）

【3】稳定性（可靠性 · 越高越好；稳定 ≠ 僵化）
  - 健康度评级方向一致（同数据下 10 次评级应相似，灯色众数占比 ≥ 80%）
  - 关键原因收敛（seq 11 原因 1/2 所引 key signal 的 IoU ≥ 60%）
  - seq 12 跟踪指标选择一致（10 次中 TOP 指标命中率高）
  - 字数/时长波动小（内容饱满但不冗余 · CV 低）
