+   - V10.524 將「待刷新」變成可操作入口：商品看板 PChome 補抓產線新增「刷新過期 120 筆」按鈕，呼叫 `/api/ai/pchome-match/refresh-stale` 背景執行 `run_expired_identity_refresh()`，只刷新既有 `identity_v2` 的 PChome product_id，不跑 fresh search recovery、不呼叫 LLM，完成後重算 AI 挑品並清除 Dashboard / 競價快取。
    - V10.523 補一批高分真同款 exact identity 比價規則：Beauty Foot 足膜、KAMERIA 積雪草足膜、TS6 蜜愛潤滑液 / 蜜桃煥白凝膠 / 極淨白+煥白組合、Vaseline 嬰兒高純修護凝膠在規格、入數、品牌與品線完全對齊時可進 `exact / total_price / price_alert_exact`，讓可用比價覆蓋增加；同時保留 TS6 香味衣物手洗精等 variant-sensitive 款式在 `manual_review`，不放寬全域門檻。
    - V10.522 將 PChome 補抓狀態 API 接上 read-only coverage snapshot：`/api/ai/pchome-match/backfill/status` 會同步回傳身份覆蓋、新鮮率、待刷新與待補抓數，Dashboard 補抓產線即使沒有最近任務結果，也能直接判讀下一步該刷新過期價格或補抓未搜尋商品。
    - V10.521 將比價新鮮度 stale 指標上屏：首頁 KPI / PChome 補抓產線 / daily / growth 都顯示價格過期數，讓操作員分清「已確認同款但價格待刷新」與「尚未找到身份配對」；過期 identity refresh 也優先刷新 `total_price / price_alert_exact` 的正式價差配對。

 ## 📅 詳細更新日誌 (考古存檔)
 
 ### 2026-06-01：PChome 比價新鮮度操作閉環
+- **V10.524 PChome 過期價格刷新手動入口**: 商品看板 PChome 補抓產線新增「刷新過期 120 筆」按鈕與 `/api/ai/pchome-match/refresh-stale`，背景執行既有 `run_expired_identity_refresh()`，只刷新已建立 `identity_v2` 的 PChome product_id，不跑 fresh search recovery、不呼叫 LLM；完成後重算 AI 挑品並清除 Dashboard / competitor intel cache，讓 `stale_matches` 從觀測指標變成可直接操作的任務。
 - **V10.523 高分真同款 exact identity 比價規則補強**: 針對正式環境反覆出現、分數已達 1.0 但因 `multi_component_pair` 或 variant review gate 被留在人工審核的真同款，補 Beauty Foot 足膜、KAMERIA 積雪草足膜、TS6 蜜愛潤滑液 / 蜜桃煥白凝膠 / 極淨白+煥白組合、Vaseline 嬰兒高純修護凝膠 focused exact identity。這些案例只有在品牌、品線、容量 / 重量與入數完全對齊時才進 `exact / total_price / price_alert_exact`；TS6 香味衣物手洗精等款式敏感商品仍維持 `manual_review`，全域 `MIN_MATCH_SCORE` 與 overwrite 保護不變。
 - **V10.522 PChome backfill status 附帶 coverage snapshot**: `/api/ai/pchome-match/backfill/status` 在背景任務狀態外同步回傳 read-only `fetch_competitor_coverage()` 摘要，包含身份覆蓋、新鮮率、過期價格與待補抓數；Dashboard 補抓產線即使尚無最近 run result，也會顯示「身份覆蓋 / 新鮮 / 待刷新 / 待補抓」，讓操作員能分辨下一步該跑 expired identity refresh 還是 unmatched backfill。此狀態端點不寫 DB、不呼叫 LLM、不抓外站。
