 Smoke test for: 彻底修复底层写入路径与掩膜联动
 
 验证三件事（不依赖 GUI / 不实例化 Pipeline，避免触发 osgeo/gdal 导入）：
-  1. pipeline.step10_map 内部对 output_image_path 的 override 逻辑正确：
+  1. Step12KrigingHandler.execute 内部对 output_image_path 的 override 逻辑正确：
      - 路径不在 visualization_dir 下 → 被强制重定向
      - 路径在 visualization_dir 下 → 保留
      - 路径为 None/空 → 用 forced 默认值
   2. step11_map_panel.update_from_config 含 pipeline.get_step_output_dir('step1') 调用
   3. _step_path_resolver._FALLBACK_DIR_TABLE['water_mask'] == '1_water_mask'
+
+注：原 water_quality_inversion_pipeline_GUI.py 已删除，
+    step10_map() 逻辑已迁移至 Step12KrigingHandler（src/core/handlers/step12_kriging.py）。
