+   - V10.476 補 PChome 商品比對「商業條件差」防線：即期品、效期/保存期限、盒損、福利品等條件若只出現在單側，matcher 會加 `commercial_condition_gap` + `variant_selection_review`，保留高分但不讓 rescore 自動進 accepted queue。這可避免 3W CLINIC 粉底液、KAMERIA 足膜、Sisley 全能乳液這類同名但商品狀態不同的候選被當成一般正品價差。
    - V10.475 補 PChome rescore 操作與高分錯配防線：`scripts/audit_competitor_match_attempt_rescore.py` 預設不再只掃 `strong_exact_spec_match`，避免漏掉 `focused_exact_*` 等新版 matcher 理由；matcher 新增暖燈 S/M/L 尺寸差、NITORI 香氛噴霧器型號差的 hard veto，並把彩妝色號單邊出現的高分候選送進 `variant_selection_review`，避免 LA MER 氣墊等色號型商品被誤入 accepted queue。測試：`tests/test_marketplace_product_matcher.py`、`tests/test_competitor_match_attempts_persistence.py`、`tests/test_competitor_match_attempt_rescore_audit.py` 通過。
    - V10.474 補 PChome near-threshold matcher / feeder 下一階段：新增 HOOOME 白色經典香氛暖燈與 Gdesign Aroma Lava 2.0 的窄範圍 total-price exact 回收；Recipe Box 可撕式水性兒童指甲油只進 identity_review，不自動寫正式價差；Pavaruni 蠟燭 vs 精油、DASHING DIVA 不同款式仍維持 veto/低信心。known-id refresh 現在會對 hard-veto 舊候選執行 fresh search recovery，missing known-id 若 fresh search 只找到低分候選也會保留 best candidate + diagnostics，而非落成 `refresh_no_result`；正式覆寫保護新增 stronger existing guard，避免較弱新候選以高分覆蓋既有強正式配對。測試：`tests/test_marketplace_product_matcher.py`、`tests/test_competitor_match_attempts_persistence.py`、`tests/test_competitor_match_attempt_rescore_audit.py` 通過。
    - V10.473 補背景 embedding host_health skip：`allow_111_fallback=false` 會讀最近 `host_health_probes`，跳過 runtime unhealthy 的 GCP 節點（預設 20 分鐘，DB fail-open），避免每筆任務都等待已知壞節點 timeout；路由安全不變，不把背景 embedding 落 111。
