 【已完成】
+   - V10.561 補 PChome 比價補強前端分段回饋：Dashboard 的 PChome 卡片從「補抓產線」改為「比價補強產線」，按鈕與確認文案同步說明會先刷新舊 identity、再重評近門檻與補抓未配對；結果區新增刷新 / 重評 / 補抓三段 matched/total 摘要，避免後端已完成分段統計但操作員仍只看到一個籠統成功數。
    - V10.560 串起手動 PChome 比價補強三段式流程：`/api/ai/pchome-match/backfill` 現在不只跑近門檻重評與未配對補抓，也會先用小批次 `run_expired_identity_refresh()` 刷新已知 `identity_v2` 舊價格，讓操作員按一次補強就能同時處理「舊 identity 新鮮度」、「near-threshold low_score」與「pending identity」三條主線。結果 payload 新增 `stale_identity_refresh` 分段統計，方便後續 Dashboard / 簡報 / AI 決策知道覆蓋率改善是來自刷新、重評或補抓。
    - V10.559 收斂 retryable 有效身份新鮮度：`_fetch_retryable_candidate_skus()` 不再把 `expires_at IS NULL` 的舊 PChome `identity_v2` 當成有效阻擋條件，只有明確 `expires_at > CURRENT_TIMESTAMP` 的新鮮 identity 才會阻止 near-threshold revalidation。未知新鮮度仍走 V10.551 的 expired / recovery 刷新入口，重評後仍必須通過最新版 matcher、hard-veto、auto write safety 與既有正式候選覆寫保護，避免為了拉覆蓋率犧牲準確率。
    - V10.558 補 legacy focused identity reason 回刷窄門：舊 attempt 若沒有新版 `focused_exact_total_price_safe` marker，但已帶具名 `focused_exact_identity_*` 且該 identity 屬於 matcher total-price safe set，並且舊分數已達全域 `MIN_MATCH_SCORE`，可進近門檻重評。這補上歷史資料缺 marker 的漏接情境；仍要求無 hard veto、`exact_identity`、無 commercial / variant / count / bundle 阻擋，最後由最新版 matcher 決定是否能寫正式價差。

 ## 📅 詳細更新日誌 (考古存檔)
 
 ### 2026-06-01：PChome 比價新鮮度操作閉環
+- **V10.561 PChome 比價補強前端分段回饋**: Dashboard 的 PChome 操作卡改名為「比價補強產線」，手動按鈕與確認文案同步說明三段流程；結果摘要會顯示刷新、重評、補抓各自的 matched/total，讓操作員能判斷覆蓋率改善來自舊 identity 新鮮度回補、近門檻 matcher 回刷，或 pending 商品 fresh search 補抓。
 - **V10.560 手動 PChome 比價補強三段式串接**: `/api/ai/pchome-match/backfill` 與每日 scheduler 口徑對齊，手動執行時先小批次刷新過期 `identity_v2`，再跑近門檻候選重評，最後補抓高優先未配對商品。回傳結果新增 `stale_identity_refresh` 分段統計，讓後續 Dashboard、簡報與 AI 決策能區分覆蓋率改善來自舊 identity 新鮮度回補、matcher 回刷，還是 fresh search 補抓。
 - **V10.559 retryable 有效身份新鮮度收斂**: `_fetch_retryable_candidate_skus()` 的既有 identity 阻擋條件改成只接受 `cp.expires_at > CURRENT_TIMESTAMP`，不再讓 `expires_at IS NULL` 的未知新鮮度舊配對壓住近門檻候選回刷。未知新鮮度仍由 expired identity refresh / recovery 路徑處理，最後寫入仍必須通過現行 matcher、hard-veto、auto write safety 與 stronger existing production match 保護。
 - **V10.558 legacy focused identity reason 回刷補漏**: `_fetch_retryable_candidate_skus()` 在 V10.557 的具名 identity guard 之外，補上歷史資料缺 marker 的情境：舊 attempt 若沒有新版 `focused_exact_total_price_safe`，但已有具名 `focused_exact_identity_*` 且該 identity 屬於 matcher total-price safe set，並且舊分數已達全域 `MIN_MATCH_SCORE`，可進近門檻重評。仍要求無 hard veto、`exact_identity`、無 commercial / variant / count / bundle 阻擋，最後由最新版 matcher 決定是否能寫正式價差。
