 -- AI_CHANGELOG:
+-- - 日期: 2026-02-17
+-- - Prompt: ods-dedup-standardize Task 5.1
+-- - 直接原因: ODS 去重标准化需要 DISTINCT ON (pk) ORDER BY pk, fetched_at DESC 查询模式的索引支持
+-- - 变更摘要: 为全部 23 张 ODS 表添加 (业务主键, fetched_at DESC) 复合索引定义
+-- - 风险与验证: DDL 文档性文件，新环境初始化时自动创建索引；已有环境通过迁移脚本部署
+--
 -- - 日期: 2026-02-14
 -- - Prompt: P20260214-070000 — ODS 清理与文档标注（5 项任务）
 -- - 直接原因: option_name（store_goods_sales_records）和 able_site_transfer（member_stored_value_cards）在 API 中不存在且全 NULL，需从 DDL 中注释化
