 ## 📅 詳細更新日誌 (考古存檔)
 
 ### 2026-05-21：瀏覽器測試守門與 PChome 熱路徑優化
+- **V10.392 組合包件數防錯配**: marketplace matcher 新增 `multi_component_count_conflict`，當 MOMO 與 PChome 都是 `+`/`＋` 組合包但組件數不同時直接進 `not_comparable`，避免三件組被拿去跟兩件組做總價告警；同步把該原因加入 evidence flags，讓告警與審核畫面可以清楚顯示「組合包件數不同」。
 - **V10.391 多款任選 catalog listing 防錯配**: marketplace matcher 新增 `catalog_variant_listing_alignment`，當 MOMO/PChome 雙方都是多款/多色/多香味任選 listing，且商品線、規格與類型一致時，可放行香氛擴香罐、香氛蠟燭等 catalog 型同款；同時把 Relove 菸鹼醯胺 vs 胺基酸私密清潔凝露列為變體衝突，並讓 competitor feeder 不再只因 `strong_exact_spec_match` 就把低分候選視為 recoverable，避免只同規格但品線不同的商品回寫正式比價。
 - **V10.390 PChome 近門檻商品比對規則**: marketplace matcher 補 17 組近門檻真同款召回與錯配防線，包含 OBgE 防曬棒、ARTMIS 私密清潔慕斯、Seche Vite 快乾亮油、TAICEND 屁屁噴、femfresh / VIGILL 私密清潔、Solone 眼部飾底乳、HYDSTO 車載香薰、小米 S101 刮鬍刀、PRAMY 定妝噴霧、I'M MEME 修容打亮棒、檜山坊滾珠精油、ARM&HAMMER 體香膏、Brush Baby WildOnes 電動牙刷與 Palmer's 按摩乳；同時把香氛/私密慕斯/定妝噴霧 finish 差異列為 variant-sensitive，避免不同香味、蔓越莓 vs 金縷梅、柔焦霧面 vs 水光亮面被誤推成直接價格告警。
 - **V10.388 精華乳 / 精華霜變體防錯配**: marketplace matcher 新增精華類 formulation conflict guard，當共享 identity anchor 只到「精華」但一側是「精華乳」、另一側是「精華霜 / 精華液」時會標記 `variant_descriptor_conflict` 並壓低同款分數，避免自白肌等同品牌相近品線被錯推成 PChome/MOMO 可直接價格告警。Competitor feeder 同步會用最新 matcher 重新驗舊配對；若舊 `identity_v2` 已被現行 matcher 判成低分或 veto，允許新的高信心候選替換，避免歷史錯配卡住正式 `competitor_prices`。
