+## 追加修复（需求创建 500）
+
+- 触发问题：
+  - 需求管理页面创建需求失败，接口 `POST /api/v1/requirements` 返回 `500 Internal Server Error`。
+- 根因：
+  - `api/app/services/requirement_service.py` 的 `_next_requirement_code()` 使用 `datetime.utcnow()` 但文件缺少 `datetime` 导入，运行时报 `NameError: name 'datetime' is not defined`。
+- 处理：
+  - 在 `api/app/services/requirement_service.py` 增加 `from datetime import datetime`。
+- 验证：
+  - `python3 -m compileall api/app/services/requirement_service.py` 通过。
+  - `docker compose up -d --build api` 重建 API 容器成功。
+  - 复测 `POST /api/v1/requirements` 返回 `200`，并成功创建需求（示例 `code=REQ-2026-0001`）。
