 ## 九、回滚
 
 本轮改动遵循"边界内最小改动"，无破坏性数据库结构变更。如需回滚，按部署前的文件/库备份还原即可。
+
+## 附：历史数据归属订正（可选，一次性）
+
+用于修复历史数据（新数据已自动带归属，无需执行）：
+- `companions.user_id` 为空 → 按"昵称唯一匹配用户"回填；
+- `finance_records.user_id` 缺失(0/NULL) → 按充值/提现/订单/对手方规则回填。
+
+默认只**预览**，确认无误后再 `--apply`（脚本幂等，可重复执行）：
+
+```bash
+cd server
+npx tsx scripts/backfill-ownership.ts            # 预览（不写库）
+npx tsx scripts/backfill-ownership.ts --apply    # 写库
+```
+
+输出会给出 `total / linked / ambiguous / noUser / filled / skipped` 统计与样例，便于核对。
