## Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| — | — | — | — | 无发现 |

扫描了以下文件的 TODO/FIXME/PLACEHOLDER/空返回模式：
- `internal/service/asset/service.go` — 无问题（`return nil` 均为合法的辅助函数返回）
- `internal/store/postgres/device_sim_binding_store.go` — 无问题（`return nil` 为事务内幂等安全分支）
- `internal/gateway/device.go` — 无问题
- `internal/gateway/models.go` — 无问题
- `internal/bootstrap/services.go` — 无问题

---

## Human Verification Required

无需人工验证。所有行为均可通过代码检查 + DB 验证 + 编译检查自动确认。

以下场景为运行时行为，在实际调用时自然验证：
1. **实际 Gateway 连通性** — sync-info 调用需真实 Gateway 服务，本次编译验证代码路径正确，运行时验证留给集成测试
2. **is_current 原子性** — 并发场景下的唯一性由 GORM Transaction 保证，代码逻辑已验证

---

## Gaps Summary

无 gaps。Phase 03 全部产出均已实现并验证：

- **Plan 01**（数据基础层）：2 个迁移对（000090/000091）已执行，DB 列已确认存在；Device/DeviceSimBinding 模型更新完整；Gateway SyncDeviceInfo 方法实现正确；DTO 扩展（DeviceResponse 5字段 + IsCurrent 2处）完整
- **Plan 02**（Service 层接入）：UpdateIsCurrentByDeviceID 事务两步原子更新已实现；asset.Service 注入 gatewayClient；updateDeviceFromSyncInfo 私有函数完整（5字段更新 + is_current 原子更新）；Refresh device 分支接入 sync-info（nil guard + Warn 日志，不阻断主流程）；bootstrap 正确传入 deps.GatewayClient
