+## Session 3: 积分重注册余额恢复验证
+
+**Date**: 2026-04-13
+**Task**: 积分重注册余额恢复验证
+
+### Summary
+
+完成 register_bonus_claims 快照方案的本地迁移与集成测试验证，确认删除账号后重注册可恢复删除前积分余额。
+
+### Main Changes
+
+| Feature | Description |
+|---------|-------------|
+| DB Migration | 通过 `dev-migrate.sh migrate` 应用 `20260413_0004_register_bonus_claims_snapshot`，新增 `first_user_id_snapshot` 与 `balance_snapshot`，移除 `first_user_id`。 |
+| Restore Logic | 注册流程优先读取 `balance_snapshot` 恢复余额；删除账号前写入当前余额快照。 |
+| Integration Tests | 新增未消费删号重注册恢复场景，并更新已有消费后删号重注册断言。 |
