"""遗留入库与批量处理脚本。

按 ARCHITECTURE.md Phase 4 要求，从 ``interface/Preprocessing.py`` 迁出。
类型：LEGACY（非运行时，仅用于历史数据迁移或调试）。

原位置：``interface/Preprocessing.py`` 中以下函数：
    - ``persistenceData`` — 将中间结果保存到数据库（线上不执行）
    - ``persistenceData1`` — 将实体/句子中间结果保存到数据库（线上不执行）
    - ``_handle`` — 批量表格解析的子任务处理函数
    - ``getPredictTable`` — 批量表格预测脚本入口

``interface/Preprocessing.py`` 仍 re-export 以上全部名称，老 import 不受影响。
