+- **范式步骤：** AI编码实现
+- **修改摘要：** 修复gixsql DB数值差异问题：回滚旧方案（修改length导致over-read修复不完整），实施新方案（DB后处理power缩放）。从_pp.cbl的INSERT SQL和GIXSQLSetSQLParams中提取列名→power映射，COBOL执行后对SQLite DB执行`CAST(col AS REAL) / 10^|power|`修正数值。修复了3个bug：(1)列名映射错误（HV_ANNUAL_H→ANNUAL_LEAVE_H），(2)SQLite整数除法截断（需CAST AS REAL），(3)INSERT SQL多行解析（FILLER VALUE + &续行）
+- **涉及文件：** `runners/gixsql_runner.py`（新增`extract_power_scaling`、`apply_power_scaling`、`_patch_numeric_metadata`），`orchestrator_db.py`（集成DB后处理调用）

 - **修改摘要：** 修复 Java Runner 未传递 command_line 参数的 bug：在 `orchestrator_db.py` 的 `_java_run_scenario` 方法中添加 command_line 参数传递逻辑，对齐 COBOL runner 的处理方式。修改后 Java 程序能正确接收 YEARMONTH 参数。
