+
+2026-08-20 数据补全 P1+P2+P3:
+- P2 历史回灌: profit(利润)+dupont(杜邦) 2015Q1+ 按季分片, 日预算内自适应续跑
+  (state 文件推进, 幂等), 约 2 季/天 × ~46 季 ≈ 3 周自动跑完
+- P1 增量: 回灌完成后拉当季+上一季(兜住晚披季报), 2 表 × 2 季 × 全 A ≈ 22k query
+- P3 业绩报告: forecast(业绩预告 2003+)/express(业绩快报 2006+), 每股一次调用与
+  区间无关 → 月首周日全区间恒定 2×N query 幂等拉齐
+- 落 parquet data/fundamentals_baostock/{table}.parquet, 保留 pubDate 列
+  (读侧按 pubDate<=date 过滤防前视偏差, 同 fundamentals-lookahead-bias-fix 模式)
+
+预算(单 IP 48000/天, 用户铁律"每天限额不要超"):
+    bs_eod ~11k(18:05) + 本脚本 DAILY_CAP=30000(23:05 串行) = ≤41k;
+    月首周日叠 reports 2×N ≈ 11k → 44.3k < 48k, 余 3.7k。
+    开跑前探 sanguo-bs-eod 是否仍在跑(18:05+4.6h 极端尾=22:41), 在跑则 exit 0
+    次日幂等补 —— 同 IP 永不双连接(封禁红线是并发不是重试)。
