 【已完成】
+   - V10.331 強化 PChome 比價 matcher 邊界：正式端 pilot 先刷新 30 筆過期 identity_v2、補抓 15 筆高價未配對 SKU，確認 structured diagnostics 開始寫入；針對「同品牌、同核心多組件、無任何否決理由、價格正常」但因規格文字不完整卡在 0.74x 的候選，新增 strong_component_line_match 窄門補分，避免 Gennies 類完整套組被誤留在低信心，同時維持雙入組對單品、容量衝突、不同品牌與補充瓶硬否決。
    - V10.330 補市場情報 candidate queue review AI summary Telegram dispatch report run receipt：新增 read-only report run receipt builder、POST endpoint、UI 按鈕與 deployment readiness smoke target，在 report run readiness 後審核人工/獨立 job 產出的 report receipt、artifact path/hash、必要章節、summary hash 與 runtime boundary；API/UI 不讀 approval/Telegram token、不呼叫 LLM、不補產報表、不派送 Telegram、不開 DB、不寫檔、不更新 review_state、不掛 scheduler。
    - V10.329 優化 `/growth_analysis` 冷快取策略：source fingerprint 未變時，成長分析共享快取由 30 分鐘延長為 6 小時有效；每日匯入仍會主動清除快取，避免資料更新後沿用舊圖表，同時降低正式端重啟或冷 worker 重新掃 `realtime_sales_monthly` 的 14 秒級等待。
    - V10.328 強化 MOMO/PChome 核心比價準確性第一波：補高頻品牌 alias、中文商品線 bigram 訊號、保健/包裝同義單位與買送件數解析，搜尋詞改為品牌/核心/主規格三層；PChome 比對嘗試與正式快照補存 URL、圖片、庫存與結構化 diagnostics，商品列表用 tone 分流顯示尚未搜尋、低信心、身份否決、單位價與過期狀態，不再把不同問題全部壓成灰色待比對；同步持久化首頁 / PChome coverage 熱路徑索引，避免重開機後慢查詢回歸。

 ### 2026-05-20：重開機後首頁熱路徑索引持久化
 - **Dashboard / PChome 慢查詢修復**: 主機重開機後 `https://mo.wooo.work/` 首頁可用但多次逾時，實際瓶頸集中在首頁與 PChome coverage 查詢掃描 `products`、`price_records`、`competitor_match_attempts`。線上先補三個索引讓首頁恢復 200，並新增 `migrations/040_dashboard_hot_path_indexes.sql` 將修復持久化到 fresh restore / DB rebuild 流程。
 - **Growth Analysis 冷快取修復**: `/growth_analysis` 在 `monthly_summary_analysis` 落後時會改掃 `realtime_sales_monthly` 聚合，冷計算約 14 秒；修正為 source fingerprint 未變時延長共享快取有效期，匯入流程仍主動清除快取，避免資料未變卻反覆掃大表。
+- **PChome backfill pilot**: V10.328 diagnostics 欄位上線後先跑小批次，刷新過期 identity_v2 30 筆（11 筆成功更新）、高價未配對 15 筆全被低信心/單位價擋下；樣本確認多數 hard veto 正確，另補 `strong_component_line_match` 處理 Gennies 類同品牌完整多組件套組。
 
 ### 2026-04-29：ADR-017 Phase 3f 模組化收尾啟動
 - **DB metadata 救急**: `database/manager.py` 改為顯式載入 permission / AI / autoheal / import / vendor / realtime_sales ORM，PostgreSQL 初始化透過 process-local guard + advisory lock 執行 `Base.metadata.create_all()`，避免新環境漏表與一般流量重複碰 DDL。
