+# ARTEMIS 2.4.0
+
+本版改进批量用例人工评审与执行详情阅读，并包含 OpenAI SDK 适配、安全依赖更新、Windows 资源锁和报告证据修复。配套「任务人工评审」独立发布 **1.1.0**。
+
+## 人工评审与原始用例
+
+- 安装并启用人工评审 1.1.0 后，批量模板在原七列后增加「预置条件、操作步骤、预期结果」，仍接受七列旧模板。未启用插件时保持原有七列模板和校验；新增内容不进入 AI 提示词。
+- 左侧标题为用例编号与用例标题，下面依次展示三项原始内容；历史任务未保存的内容显示缺失，不用 AI 提示词替代。
+- 「AI执行准确性」改为「用例执行准确性」，保留字段 ID 和既有评审；备注框缩短，可自行拉高。
+- 「上一条／下一条」放在保存评审下方。同批次按已结束任务顺序切换，独立任务使用当前历史列表。
+- 选择结果立即保存，备注停止输入 600 毫秒后保存，切换前也先保存。失败时保留输入和当前用例，允许手动重试；连续修改不会被较早回执覆盖。打开任务不会自行填写或保存评审。
+- Flash、Pro、探索以及安卓、电脑、跨端任务均可显示面板，步骤与视频视图均支持。
+
+## 执行详情与报告
+
+- Payload、原始结果及超长、多行调试字段默认折叠；展开后限高滚动，全文可读，不截断保存的证据。
+- 修复正式验收通过但没有单独输出正文时出现「没有保存最终结论」的误导提示，报告按有效结论生成说明。
+- 安卓截图的真实保存回执进入结构化来源汇总，保留路径与哈希；窗口枚举没有单一目标时说明原因，不误报截图丢失。
+- 电脑任务记录真实宿主平台；来源窗口标题变化时提示查看原始步骤。结果目录区分通过、不通过、阻塞与未验证。
+- 历史模型和思考强度优先读取任务自身诊断，用量统计保留实际请求模型，减少历史条目被当前配置误标；修复步骤、队列与录屏收尾相关读取问题。
+
+## 模型、依赖与运行稳定性
+
+- OpenAI Python 更新为 3.40.0，配套 LangChain 1.4.7、langchain-core 1.7.0、langchain-openai 1.7.3；httpx 保持兼容的 0.28.1。Python 与前端安全依赖更新写入锁文件。
+- 新增仅环境配置 `OPENAI_USE_SYSTEM_PROXY=false`，模型请求默认不采用系统代理。需要代理时在 `.env` 设为 `true` 并重启；同步、异步请求和 OpenAI 连接检查一致，TLS 与自定义 CA 校验继续保留。
+- 修复 Windows 临时目录 awake 锁访问失败及所有权恢复，检查同类资源锁和运行时收尾。持久权限错误仍保留实际原因，不跳过互斥保护。
+- 规划器明确区分规划阶段与执行器的插件能力，避免因本阶段没有动作工具而误判插件不可用；批次模型失败保留明确诊断。
+
+## 验证范围
+
+本轮开发默认后端测试 **3263 通过、2 跳过、8 按标记排除**，前端 **347 项通过**；生产构建、Ruff 格式与静态检查、质量基线和核心类型检查通过。Windows 浏览器隔离夹具覆盖深浅色、宽窄布局、视频视图面板、自动保存与切换，以及长 Payload 折叠。未写入真实任务人工评审。
+
+此前用户重启后的实际复测中，5 项正式用例通过 AI 验收，另有 1 项电脑路径探索通过，覆盖安卓、电脑与跨端；该样本没有发现 awake 锁访问失败。此结果不等于重跑原 192 项业务批次，未完成大批次压力及 macOS/Linux 实测。本次发版不构建 Docker，不重启用户服务。
+
+## 升级与下载
+
+等待当前任务结束后运行 `update.bat`（国内镜像用 `update-cn.bat`），完成后运行 `start.bat` / `start-cn.bat` 并刷新网页。需要人工评审新功能时，再从插件市场升级并启用 [任务人工评审 1.1.0](https://git.playones.com/chenmingxuan/Artemis-Plugins/releases/tag/task-review-v1.1.0)。插件要求 ARTEMIS 2.4.0+；升级主程序不会自动升级或授权已安装插件。
+
+源码附件为 `artemis-2.4.0-source.zip` 和 `SHA256SUMS.txt`，保留浅层 Git 更新能力，不包含用户配置、凭据、历史任务、依赖目录或预构建网页。工作区扩展接口见 [插件文档](../workspace-plugins.md)。
