+### 缺陷清单
+
+| 编号 | 描述 | 严重级 | 状态 | 修复反馈 | 复测结果 |
+|---|---|---|---|---|---|
+| D-01 | **F-01.5 重复注册返回 400 而非 409**：验证码被首次注册消费后，二次请求因验证码失效返回 400 "验证码错误或已过期"，未到达邮箱重复检查逻辑。根因推测：验证码校验在邮箱唯一性检查之前，码失效后短路返回。 | Medium | ✅ Verified | `auth.service.register` 将邮箱唯一性检查前置（存在即抛 409 Conflict，且不消费验证码），再校验验证码 | 首次 201 → 重复 409 ✓（新 build 复测通过） |
+| D-02 | **F-07.3 未知模型错误码不符合规范**：预期 `code="model_not_found"`，实际 `code="api_error"`。根因推测：错误码映射表未覆盖 model_not_found 场景，回退到通用 api_error。 | Low | ✅ Verified | `gateway.controller` 异常映射：404（NotFoundException）→ `type/code = model_not_found`，其余保持 api_error | 404 + code=model_not_found ✓（新 build 复测通过） |

+### 反馈跟踪

+- 2026-08-09：D-01/D-02 修复完成 → `pnpm build` + `typecheck` 通过（顺带修复缺失的 `HttpStatus` 导入）→ 重启 API 复测
+  - D-01 复测：首次注册 201 → 重复注册 **409** ✓
+  - D-02 复测：未知模型 → **404 + model_not_found** ✓
+- **R01 最终裁决：✅ PASS（33/33 有效；2 缺陷已修复并验证关闭）**

+### R01 会话摘要
+
+本测试会话由 Sisyphus-Junior (DeepSeek V4 Pro) 执行，共计测试 **33 个用例**（F-13: 8, F-14: 6, 回归: 19）。环境使用 docker postgres/redis + 重建 API + mock upstream。
+
+**关键发现**：
+- F-13 支付 P4：**8/8 PASS**，核心流程（充值→支付→余额→订单→幂等→错误处理）全部通过。stripe 返回 406 而非预期的 501/400，属微小偏差，功能无损。
+- F-14 官网 P5：**6/6 PASS**，构建零错误，4 locale 均正确渲染本地化文本，导航/Logo/Widget/认证弹窗组件均经验证。
+- 回归抽样：**17/19 PASS**，**2 FAIL**（D-01 重复注册状态码，D-02 未知模型错误码）。
+
+**无阻塞性缺陷**：两个缺陷均为中等/低严重级，不影响核心业务流。
+
+**里程碑判定**：R01 轮次 **条件通过**（Conditional PASS）— 需修复 D-01/D-02 后复测关闭。
