+  - `浮標 (やぐら型) -> symbol-daytime-327`
+- 对应修正的是这类“对象没丢，但被 builder 预写成了错误 chart_icon_image”的情况
+  - 例：`fid=12011414 / 形状分類番号=323 / 表示用番号=32300002`
+  - 原始版应该是 `symbol-daytime-323`
+  - 修正前 delivery/final 被写成了 `chart_icon_image=symbol-daytime-321`
+  - 当前 compare 页 style 已补兜底并上线到 `style-r13`
 - 当前正式审计顺序已经明确为：
   - 先 `object preservation audit`
   - 再 `render audit`
