 ### 2026-05-24：PChome 近門檻身份回收第二輪
+- **V10.399 多香味 catalog 價格告警降級**: marketplace matcher 新增 `variant_selection_review`，當一側是無明確選項的商品線、另一側列出多個具名香味/款式選項時，允許同款身份回收但只進 `identity_review`，不直接進 `price_alert_exact`。首個正式案例是 HH 女性私密衣物抗菌手洗精 200ml 對 PChome 白麝香/清新花園/寶貝粉香多香味 listing；此規則避免把多香味 catalog 價格誤當單一 variant 精準比價。
 - **V10.398 true low confidence 保守回收**: marketplace matcher 針對正式前段 `true_low_confidence` 補一輪 focused exact identity lines，讓 Baan 嬰兒修護唇膏、植村秀 3D 極細防水眼線膠筆、YSL 恆久完美透膚煙染腮紅、HH 私密植萃美白緊緻凝露、Lab52 學習刷牙漱口水、Benefit 經典菲菲染唇液、Herb24 晨霧純精油擴香儀、Pavaruni 40 香味 10ml 精油與 GATSBY 爆水擦澡濕巾等近門檻真同款可被回收；未放寬 `MIN_MATCH_SCORE`。同版保留 peripera 多色任選對單一色號、LUNASOL 頰彩對眼彩組、MUJI 細軸棉棒對黑色棉棒的低信心保護，並讓多組件套組即使達強身份證據也停在 `identity_review`，避免總價被誤當精準價格告警。
