+-- 迁移：移除废弃的 dws_member_recall_index 表及 RLS 视图
+-- 日期: 2026-03-20
+-- 原因: RecallIndexTask 已于 2026-02-13 被 WBI+NCI 替代，但表和视图的 DDL
+--       在 2026-02-19 schema 重命名（billiards_dws → dws）时残留至今。
+--       表中无有效数据（ETL 任务已删除），属于孤儿对象。
+-- 影响: 无下游消费者依赖此表数据（后端 recall 维度已改用 v_dws_member_winback_index）
+-- 回滚: 从 git 历史恢复 DDL 定义并重建表和视图
+-- =============================================================================
+
+BEGIN;
+
+-- 1. 删除 RLS 视图
+DROP VIEW IF EXISTS app.v_dws_member_recall_index;
+
+-- 2. 删除索引
+DROP INDEX IF EXISTS dws.idx_dws_recall_display;
+
+-- 3. 删除表（CASCADE 会自动清理约束）
+DROP TABLE IF EXISTS dws.dws_member_recall_index CASCADE;
+
+-- 4. 删除序列
+DROP SEQUENCE IF EXISTS dws.dws_member_recall_index_recall_id_seq;
