 ## Ruff lint 清理
 
-记录日期：2026-08-30
+状态：已完成
 
-`uv run ruff check .` 当前发现 1263 条 lint 诊断。该事项暂不在本次处理，后续按批次清理并逐批运行 pytest、Pyright 和 Ruff 检查。
+完成日期：2026-08-31
 
-建议顺序：
+本轮完成了 Ruff lint 全量清理，包括未使用导入与变量、导入排序、类型注解现代化、FastAPI 依赖声明、异常处理标注、时区处理及其他规则。FastAPI 路由参数中的依赖调用通过 `web/backend/**/*.py` 的 B008 配置例外保留框架惯用写法；非 FastAPI 的可变默认对象已改为函数内惰性初始化。
 
-1. `F401`、`F841`：未使用导入和变量。
-2. `BLE001`、`S110`、`S112`：异常处理质量。
-3. `B008`：FastAPI 依赖声明模式，区分真实问题与框架惯用写法。
-4. `I001`：导入排序。
-5. `UP045`、`UP007`、`UP017`、`UP035`、`UP006`：类型注解和 Python 版本语法现代化。
+最终基线：
 
-当前基线：
-

-- pytest：104 passed
+- Ruff lint：0 条
+- Ruff format：208 个文件全部通过
