 【已完成】
+   - V10.446 修正 PChome 覆核頁輕量路徑的 overview timeout：覆核頁總覽改讀已存在的 shared dashboard cache / stale cache，沒有快取時只用目前覆核頁資料補足狀態，不再現場跑 `_load_competitor_decision_overview(session)` 的重型後備 SQL。
    - V10.445 補 PChome 覆核頁輕量渲染路徑：`filter=pchome_review` 不再先建完整 Dashboard `unique_items`，改為只查覆核當頁 50 筆商品、當前價、昨日價與週前價，再沿用同一張新版表格與人工覆核按鈕；降低核心比價覆核頁的全站資料負載。
    - V10.444 瘦身 PChome 覆核頁查詢：`fetch_competitor_review_queue_page()` 將覆核隊列總數與當頁資料合併在單一 SQL 內取回，避免 `/?filter=pchome_review` 為 count/page 重複掃 `latest_momo`、`latest_attempt`、`valid_competitor` CTE；保留狀態分流、人工覆核與正式價格寫入保護不變。
    - V10.443 補 PChome rescore 人工覆核入隊：`audit_competitor_match_attempt_rescore.py --apply-accepted` 只追加 `rescore_accepted_current` attempt 進人工覆核隊列，不直接寫 `competitor_prices` / `competitor_price_history`；商品看板新增「重算可採用」分流與狀態文案，讓可救回候選先由人審確認再正式更新價差。

 ## 📅 詳細更新日誌 (考古存檔)
 
 ### 2026-05-24：PChome 近門檻身份回收第二輪
+- **V10.446 PChome 覆核頁 overview timeout 修正**: 覆核頁輕量 render path 的總覽改讀既有 shared dashboard cache / stale cache；若快取不存在，只用目前覆核頁資料補足 review count 與狀態分流，不再即時呼叫 `_load_competitor_decision_overview(session)` 的重型 SQL，避免正式資料量下 statement timeout。
 - **V10.445 PChome 覆核頁輕量渲染路徑**: `filter=pchome_review` 直接走覆核隊列專用 render path，不再先建完整 Dashboard `unique_items`；當頁只查 50 筆覆核 SKU 的商品資料、最新價、昨日價與週前價，仍沿用同一張新版表格、狀態分流、PChome 候選說明與人工覆核按鈕，降低核心比價覆核頁的全站資料負載。
 - **V10.444 PChome 覆核頁查詢瘦身**: `fetch_competitor_review_queue_page()` 將原本 count + page 兩次重跑 review CTE 改成單次 SQL 的 `total_rows` + `paged_rows` 查詢，同步取得總數與頁面資料，降低 `/?filter=pchome_review` 對 `latest_momo` / `latest_attempt` / `valid_competitor` 的重複掃描；正式站小批次 rescore 入隊後，用於維持核心比價覆核頁可操作速度。
 - **V10.443 PChome rescore 人工覆核入隊**: `scripts/audit_competitor_match_attempt_rescore.py --apply-accepted` 只會把最新版 matcher 已通過門檻的舊低信心候選追加為 `rescore_accepted_current` attempt，進入商品看板人工覆核隊列；不寫 `competitor_prices`、不寫 `competitor_price_history`，必須由操作員按「採用同款」後才正式更新 PChome 價差。Dashboard 補上「重算可採用待審」分流與狀態文案，避免安全回刷候選混在一般低信心項目裡。
