 | 2026-06-25 | MOMO 待確認候選必須是營運比對卡 | V10.686 起首頁候選區需以 PChome/MOMO 左右對照、商品圖、價格差異徽章、同款可信度、中文確認重點與「雙開賣場 / 單開賣場」操作呈現；前端不得把 `variant_selection_review`、`source_code`、`momo_reference` 等工程 key 或資料欄位名直接顯示給營運使用者。 |

 | 2026-06-25 | 覆核 note 不得保留反向價格詞 | V10.688 起單位價覆核 note 不再使用「不應誤判為 PChome 價格壓力」這類否定式錯誤詞，改用「需先檢查 PChome 售價、折扣與組合」等可執行語句。 |
+| 2026-06-25 | 舊覆核資料輸出層也要清洗價格語意 | V10.689 起 dashboard template 會在輸出 `unit_price_insight.summary` 時清除舊資料殘留的反向價格詞，避免快取或歷史 row 繼續把錯誤字句顯示給營運使用者。 |
