-### P2-3 TypeScript 基线不通过（测试代码类型漂移）
+### P2-3 TypeScript 基线不通过（测试代码类型漂移）【已完成】
+- 修复状态：✅ 已完成（2026-03-03）
+- 修复内容：
+  - 修复 `createRequest` 与 `NextRequest` 构造参数类型不兼容问题；
+  - 修复盲盒测试中的 Prisma 事务 mock 签名、SSE 计划 mock 返回结构；
+  - 补齐路由测试上下文参数与测试数据类型字段（`reason`、`creatorId`、`isLoading/error`、`matchType`）；
+  - `npx tsc --noEmit` 已恢复通过。
 - 证据：
-  - `npx tsc --noEmit` 当前报多个错误（测试辅助类型、mock 签名、类型定义漂移等）。
+  - 修复后执行 `npx tsc --noEmit` 已无报错。
 - 影响：
   - 类型系统对回归的兜底失效；重构时风险上升。
 - 建议：
