-- Migration 039: 競品比對人工覆核決策表
|
||
-- MOMO PRO — PChome match human-in-the-loop review
|
||
-- 2026-05-20 台北
|
||
-- =============================================================================
|
||
-- 說明:
|
||
-- competitor_match_attempts 保存 matcher / feeder 每一次嘗試；
|
||
-- competitor_match_reviews 保存人工對最佳候選的處置結果。
|
||
-- 只有 review_action='accept_identity' 才會由服務層寫入 competitor_prices，
|
||
-- reject_identity / unit_price_required 只關閉覆核與保存決策，不污染正式價差。
