r"""从 data/raw 重算/更新产物 (2026-09-11) —— 维护页那四条「摄入命令」的总入口。

## 背景

`docs/说明书…v0.2.md` §11 写着「**不含**从原始数据重生成产物的链 (P0)」, 于是随包产物只能吃预生成的那份
(台账止 2024-11-21、报警止 2026-07-15), 现场把新表放进 `data/raw/<场站>/…` 也不会更新。
本脚本把这条链补上, 顺序与依赖关系如下 (都按场配置 `src.windscada.config`):

    ① scripts/windscada_alarms_ingest.py        故障报警/*.xls      → alarms.parquet
    ② scripts/windscada_workorder_ingest.py     风机故障记录/**      → workorders.parquet
    ③ scripts/windscada_watch_channels_build.py 油样报告/**         → oil_samples_index.parquet
    ── 以上三步只吃现场台账 (xls/xlsx/pdf), 快, 秒级到分钟级 ──
    ④ (--scada) 包内已有的 SCADA 侧构建器: 从 scada_10min/*.csv 重算
       powercurve → loss_monthly(availability) → curves / control / stop_events(faults)
       / temp_bins / yaw_daily / hydraulic_accum / thermal_chain / system_aux
       (这一步要逐台读 38 个 ~380MB 的 CSV, 慢; 默认不跑, 加 --scada 才跑)

## --verify: 等价验收 (本链的验收标准)

重算件必须能**复现随包件**: 逐键逐值比对 `outputs/rudong/windscada/_pre_rebuild_20260911/` 里那份
随包基线 (2026-09-11 现场修复时留的备份)。允许的差异只有两类, 都必须被点名:
  · 旧链的**已知缺陷**: 报警/工单里同一副本被收两遍、日期解析不了就整行丢弃、Excel 序列号当纳秒解析;
  · 本链的**新增覆盖**: 随包时没接的源件 (74 张台账表 vs 随包只用了 6 张)。
无法归类的差异 = 验收不通过 (退出码 4)。

用法:
    python scripts/rebuild_from_raw.py                 # 跑 ①②③
    python scripts/rebuild_from_raw.py --verify        # 只验收, 不重算
    python scripts/rebuild_from_raw.py --scada         # 连 ④ 一起跑 (慢)
    python scripts/rebuild_from_raw.py --dry-run       # 只打印各步会做什么
