+# ARTEMIS-Eapil 2.0.1
+
+2.0.1 修复 Windows 全新安装使用 Python 3.12 时，网页构建成功后管理服务立即退出的问题。已有 2.0.0 安装也建议升级；探索、插件和精选任务等功能继续沿用 [2.0.0](2.0.0.md)。
+
+## 修复内容
+
+- **全新安装可以启动网页服务**：探索存储、人工示范和收藏服务中的 `list` 方法遮蔽了同名内置类型，导致 Python 3.12 在加载后续类型注解时抛出 `TypeError: 'function' object is not subscriptable`。统一延迟求值，并增加冷启动与运行时类型注解回归，覆盖较新 Python 延迟暴露同一问题的情况。
+- **诊断强制刷新按请求生效**：连续请求落在同一个时钟刻度时，仍会重新扫描；并发请求继续合并，避免重复检查。
+- **MCP 工具描述跨版本一致**：统一 Python 3.12 与较新版本编译后文档字符串的缩进差异，保持工具目录、固定协议快照及现有显式描述一致。
+
+本版不要求升级 Python，也不更改已有配置、任务历史或插件版本。
+
+## 升级与安装
+
+1. 先结束正在运行的任务，再运行 `update.bat`；国内网络使用 `update-cn.bat`。升级程序会停止当前项目的服务与任务进程，并同步依赖环境。
+2. 完成后运行 `start.bat` / `start-cn.bat`，等待网页构建并打开页面。启动脚本只检查更新，不代替升级脚本。
+3. 全新安装下载 `artemis-eapil-2.0.1-source.zip`，解压后运行上述启动脚本。用附件 `SHA256SUMS.txt` 校验下载完整性。
+
+源码包保留浅层 Git 更新能力，不包含依赖环境、用户密钥、任务历史或预编译网页。升级主程序不会自动升级已安装插件。
+
+## 发布验证
+
+- Python 3.12 与 3.14 的默认后端测试分别为 **2952 项通过、6 项跳过、8 项按标记排除**。新增启动回归、同一时钟刻度下的诊断刷新回归及跨版本 MCP 描述回归；现有工具目录与协议快照无需修改。
+- 在 Python 3.12 隔离环境运行真实服务生命周期，首页、API 文档、收藏和探索接口均返回 HTTP 200，服务正常关闭。仅替代硬件预热和防休眠入口，数据库、队列、IPC、MCP 会话及 HTTP 服务沿用真实实现。
+- 前端 **290 项测试通过**，2.0.1 生产构建成功。Ruff 格式与静态检查、质量基线和核心类型检查通过。
+
+本次未调用付费模型或执行设备业务任务，未替用户升级或重启现有安装。
