-# This configuration is used to build and test on GitHub Actions only.
-# It is not the same configuration that is used by Google DeepMind to create release binaries.
-# The "official" binaries are built with Clang 13 on all platforms, and are linked against libc++
-# on Linux.
-#
-# We set CMAKE_INTERPROCEDURAL_OPTIMIZATION=OFF here to reduce build time.
-# It is highly recommended that this is set to ON for production builds.
-#
-# Build speed notes:
-#   * The compiler matrix lives in build_matrix.json. Pull requests build the
-#     representative "core" subset; pushes to main run the full compiler sweep.
-#     (See generate_matrix() in build_steps.sh.)
-#   * Studio/Filament and WASM are NOT built in the main matrix - they are covered
-#     by the dedicated `studio` and `wasm` jobs below. WASM in particular is built
-#     with emcc, which ignores the host compiler, so building it per-compiler added
-#     no coverage.
-#   * ccache is used to wrap the compiler. PR branches fall back to main's cache, so
-#     the expensive (and pinned) Filament build is restored rather than recompiled.
-
-# TODO(matijak): Consider switching Windows to Ninja builds only, this configures slightly faster
-# and brings Windows in line with other OSes. Also we wouldn't need to specify the --config option
-# in the build step because Ninja doesn't support multiple configurations (unlike MSBuild).

+
+### 网站发布与安全精简
+
+- 版本号与锁文件根包元数据同步为 `1.0.5`，不升级依赖；包含下述完整安全精简及网站导入选项清理。
+- 网站已发布 `20260929T014129Z-v1-0-5`，上一版本 `20260928T035026Z-import-options` 保留为回滚目标；白名单发布包校验、离线构建、运行时契约预检、容器健康检查及 OpenResty 配置校验通过。前后端成对切换，访客会话重建，原服务器密钥 stat 与持久预算数据库 inode 保留。
+- 发布前重新通过九项门禁/双构建：前端 156 文件/797 项，后端 166 通过/27 项既有 opt-in 跳过；只更新版本元数据，没有升级依赖。
+- 公网非付费验收 14/14 通过（网站/iframe/导入/会话/Python/预设 8 项，内置机器人与双相机 6 项）；28 个线上静态文件匹配发布清单，公网 HTML/主 JS 与本地构建逐字节一致。未调用付费模型、未启动真实训练。
+- 发布证据：`build/website-deployment/v1.0.5/`；本地门禁：`build/code-simplification/release-v1.0.5/`。
+
+### 代码安全精简（2026-09-28）
+
+#### 最终交付汇总
+
+全部 14 个计划阶段完成；基线为 `7ebe9092ba29a6674d6f5c4153f31214dd6f2319`。以下规模与限制记录截至精简计划验收时（当时未提交、打标签或部署），不含后续版本发布元数据和文档更新；发布结果见本版本条目。
+
+| 宿主文件（`web_platform/src/`） | 基线行数 | 最终行数 | 宿主减少 |
+| --- | ---: | ---: | ---: |
+| `app/App.tsx` | 3272 | 1217 | 2055 |
+| `simulation/SimulationSession.ts` | 1417 | 1210 | 207 |
+| `viewer/MuJoCoViewer.ts` | 1391 | 1267 | 124 |
+| `training/LocalTrainingPanel.tsx` | 1178 | 807 | 371 |
+| **合计** | **7258** | **4501** | **2757** |
+
+- **迁移与新增边界**：30 个新增生产模块，共 4897 行，包含迁移实现、导入、显式类型/端口、Hook 依赖与组合代码，不是净删除量。App 新增 16 个领域/界面 Hook、3 个组合组件和命令组件；项目清单辅助 1 个，Session 类型/采集模块 2 个，Viewer 几何/展示模块 2 个，训练表单/展示模块 5 个。
+- **实际清理**：删除 4 个已证实无用声明，相关生产代码净减 23 行；另将 3 个内部辅助函数取消 export。数值算法、公开兼容类型、协议/Golden 和真实扩展入口未删。移除 App 已无用途的全文件依赖检查豁免，没有新增豁免。
+- **净变化口径**：计入 Git 跟踪变更和本次未跟踪源码/测试；生产代码净增 **2117 行**（不是净删 2757 行），测试净增 **3096 行**（19 个新测试文件 3093 行，既有 E2E 追加 3 行断言）。文档净增 **137** 行，全仓净增 **5350** 行；忽略目录 `plans/`、`build/` 及生成产物不计入。逐文件数据见 `build/code-simplification/final-size-report.json`。
+- **模块边界**：资源/ref 单一所有者；地图交互与创作文件事务分开，避免万能编辑 Hook；没有新全局 store。App 保留显式领域接口和布局，最终 1217 行高于参考目标，未为行数强行压缩或引入共享万能 context。
+- **验证**：前端 156 文件/797 项（较基线新增 19 文件/117 项），后端 166 项通过；typecheck、TS/Python lint、双构建、契约哈希及 diff 检查通过。生产运行时依赖图 239 模块/540 条边，无循环。Session 101 / Viewer 131 个非提取成员逐字未变，物理时钟/控制权/几何资源释放保留原实现。
+- **浏览器验收**：计划 63 项全部通过：本地 App/布局 41，网站 5，内置机器人生产构建/开发 StrictMode 各 6，语言控制 5。双相机的既有姿态阈值未变，新增切换/隐藏后时间仍为 0.000 s 的断言。另用独立本地浏览器专项确认工具 tab 与侧栏隐藏/显示保留训练表单状态且没有 API/训练连接请求。
+- **模式隔离**：网站无训练/外控入口及 tuning HTML/chunk，本地均保留；两者保留 Python、ONNX、语言控制、导入和相机功能。业务 MODE 判断仍只在 `websiteConfig.ts`，Vite 构建判断未改，无新增模式框架。
+- **跳过/限制**：训练服务 24 项既有 opt-in 跳过（4 项真实环境/GPU smoke 或 rollout、10 项需显式预训练源、9 项真实单文件探针、1 项 CPU runner）；决策服务 3 项原生 Codex opt-in 跳过。未启用上述开关、未访问生产/付费上游、未启动真实训练；不把本次结构验收当成所有物理任务收敛证明。浏览器仅用进程级文件轮询绕过系统 inotify 额度，未修改系统限制；保留既有第三方 externalization/大 chunk 构建警告，最终前端 lint 无警告。
+- **证据**：最终门禁 `build/code-simplification/final-verification-verified/`；契约/成员/依赖核验 `final-verification/`；完整浏览器日志与专项截图 `final-browser/`。原始失败与修正后的日志均保留，未放宽门禁、协议或既有数值容差。
+

-## Contributing
-
-### Reporting bugs
-
-How to submit a good bug report:
-
-- Use a clear and descriptive title.
-
-- Make it easy to reproduce the problem. If this requires a model, attach it as
-a zip file to the bug report. The model and steps required to reproduce the
-problem should be *minimal*, in the sense that irrelevant parts are
-removed.
-
-- Clearly state what is the expected behavior.
-
-- Include an illustrative screenshot, if relevant.
-
-Try to provide context:
-
-- If the problem is new, see if you can reproduce it in an older version.
-What's the most recent version in which the problem doesn't happen?
-
-- Can you reproduce the problem on multiple platforms?
-
-### Suggesting enhancements
-
-Before submitting an enhancement suggestion:
-
-- Check if you're using the [latest
-version](https://github.com/google-deepmind/mujoco/releases/latest) of MuJoCo.
-
-- Perform a quick [search](https://github.com/google-deepmind/mujoco/issues) to
-see if the enhancement has already been suggested. If it has, add a comment to
-the existing issue instead of opening a new one.
-
-How to submit a good enhancement suggestion:
-
-- Use a clear and descriptive title.
-
-- Describe the current behaviour and the behavior which you hope to see instead.
-
-- Explain why this enhancement would be useful.
-
-- Specify the version of MuJoCo and platform/OS you are using.
-
-### Contributing code
-
-- Except for small and straightforward bug fixes, please get in touch with us
-before you start working on a contribution so that we can help and possibly
-guide you. Coordinating up front makes it much easier to avoid frustration later
-on.
-
-- All submissions require review. Please use GitHub pull requests for this
-purpose. Please consult
-[GitHub Help](https://help.github.com/articles/about-pull-requests/) for more
-information on pull requests.
-
-- Write tests. MuJoCo uses [googletest](https://github.com/google/googletest)
-for C++ tests, [absltest](https://abseil.io/docs/python/guides/testing) for
-Python binding code and [nunit](https://nunit.org/) for C# code in the Unity
-plugin. In most cases, a pull request will only be accepted if it includes
-tests. MuJoCo's internal codebase is currently lacking in test coverage. If you
-want to modify a function that isn't covered by tests, you'll be expected to
-contribute tests for the existing functionality, not just your modification. In
-fact, writing a test for existing code is a great way to get started with
-contributions.
-
-- Resolve compiler warnings.
-
-- All existing tests must pass.
-
-- Follow the [Style Guide](./STYLEGUIDE.md). In particular, adequately comment
-your code.
-
-- Make small pull requests. We will likely ask you to split up a large pull
-request into self-contained, smaller ones, especially if the PR is trying to
-achieve multiple things.
-
-- Respond to reviewers. Please be responsive to any questions and comments.
-
-- If you are not concerned with having your contribution attributed to you via
-  Git authorship, please let us know in the PR. It is significantly easier
-  for us to directly incorporate changes rather than going through the
-  full pull request import process. This will get your changes merged more
-  quickly.
-
-Once you have met all the requirements, your code will be merged.
-Thanks for improving MuJoCo!

-# MuJoCo Web 仿真平台实施计划
-
-> **计划状态**：✅ MVP 已实施并通过自动化验证  
-> **进度维护规则**：实施时将阶段/任务复选框由 `[ ]` 更新为 `[x]`，并同步“进度看板”中的状态、完成日期与备注。
-
-## Context
-
-目标是在本仓库官方 `wasm/` JavaScript/TypeScript 绑定和 Three.js 示例之上，建设一个纯浏览器 MuJoCo 仿真平台，支持模型工程上传、浏览器内文件组织、模型加载、三维展示、仿真控制和状态查看，交互布局参考 `urdf.enkeebot.com`。
-
-已确认的仓库基础：
-
-- `wasm/dist/` 有本地构建的绑定产物，但当前 `build/CMakeCache.txt` 显示其启用了线程；MVP 因此使用同版本官方 `@mujoco/mujoco` 默认单线程入口。
-- `wasm/demo_app/` 已有 Vite + TypeScript + Three.js 的最小示例，可作为加载、场景构建与逐帧同步的起点。
-- 官方绑定要求显式调用 `.delete()` 管理 Embind/C++ 对象生命周期。
-- 官方同时支持默认单线程入口与需要 COOP/COEP 的多线程入口；MVP 已确定使用默认单线程入口。
-
-## Scope / MVP 边界
-
-- **技术栈**：React + TypeScript + Zustand + Vite + TailwindCSS + Three.js。
-- **输入**：单个 MJCF/XML、单个 URDF、保留相对路径的文件夹、ZIP 工程；关联 mesh/贴图随工程导入。
-- **编辑边界**：首版只负责导入、查看和仿真，不提供 XML 编辑、热重载、工程保存或导出。
-- **物理执行**：首版使用主线程、单线程 `mujoco.wasm`；模块边界保留未来迁移 Worker 的能力，但不在 MVP 实现 Worker。
-- **控制优先级**：actuator 滑杆、关节拖动、外力施加，另含播放、暂停、单步、重置和速度控制。
-- **部署边界**：桌面浏览器中的中文界面，通过本地静态 HTTP 服务器运行；无 PWA、账号、后端、云存储或分享服务，导入工程仅驻留当前浏览器会话内存。
-- **非目标**：URDF/MJCF 互转、Xacro 展开、控制脚本、轨迹编辑与多线程 WASM。
-
-## Approach
-
-已采用 **React + TypeScript + Vite + TailwindCSS + Three.js**，在 `wasm/web_platform/` 新增独立平台应用，复用官方 WASM 包和示例逻辑，未改动 MuJoCo 核心绑定或生成产物。
-
-初步分层：
-
-1. **UI / 工程层**：工程导入、资源树、属性/控制面板、全局状态和错误展示。
-2. **应用服务层**：工程文件规范化、入口模型识别、仿真会话生命周期、命令调度。
-3. **物理层**：封装 `MjModel`、`MjData`、step/reset/ctrl，并集中管理 `.delete()`。
-4. **文件系统层**：将上传文件按相对路径写入 Emscripten MEMFS，校验引用与加载错误。
-5. **渲染层**：Three.js 场景、相机、灯光、MuJoCo primitive/mesh 映射和逐帧位姿同步。
-6. **交互控制层**：Three.js Raycaster 完成选择；关节拖动映射到 `qpos` 并调用 `mj_forward`，外力拖拽通过 `MjvPerturb`/`mjv_applyPerturbForce` 在 step 前施加。
-7. **线程边界**：MVP 直接调用主线程单线程绑定，但通过 `PhysicsAdapter` 隔离 UI，未来可在不改 UI 的情况下迁移 Worker。
-
-### 数据流、错误与生命周期
-
-- **数据流**：File/Directory/ZIP → 路径校验与入口识别 → MEMFS workspace → `mj_loadXML` → `SimulationSession` → `mjv_updateScene`/状态快照 → Three.js 与 Zustand UI。
-- **状态边界**：Zustand 只保存可序列化的工程元数据、控制参数、选择和 UI 状态；`MjModel`/`MjData`/Three.js 实例由服务对象持有，避免 React 重渲染复制 WASM 视图。
-- **错误模型**：按导入、ZIP、文件系统、模型编译、仿真、渲染分类，统一包含中文摘要、阶段、相关路径和原始错误；致命错误停止当前会话但保留工程树供排查。
-- **生命周期**：新模型采用“先释放旧渲染资源和 Embind 对象 → 清理旧 workspace → 写入新工程 → 创建新会话”的串行切换；所有失败分支使用 `finally` 回收已创建对象。
-
-## Files to modify
-
-- `Plan.md`：计划与持续进度记录。
-- `wasm/demo_app/app.ts`：只读复用来源，原则上不直接扩建为平台。
-- `wasm/package.json`、`wasm/package-lock.json`：加入 React、Zustand、TailwindCSS、`fflate`、Vitest、Playwright 及平台脚本。
-- `wasm/web_platform/index.html`、`wasm/web_platform/vite.config.ts`：平台入口、WASM 静态资源定位和相对路径静态部署配置。
-- `wasm/web_platform/src/app/`：React 壳层、布局、全局错误边界与启动流程。
-- `wasm/web_platform/src/stores/`：Zustand 工程、仿真、选择和 UI 状态切片。
-- `wasm/web_platform/src/project/`：文件/目录/ZIP 导入、路径规范化、入口识别和 MEMFS 工作区。
-- `wasm/web_platform/src/simulation/`：WASM 初始化、`PhysicsAdapter`、`SimulationSession`、步进和控制命令。
-- `wasm/web_platform/src/viewer/`：Three.js renderer、MuJoCo 场景适配、拾取、关节拖动和外力交互。
-- `wasm/web_platform/src/**/*.test.ts(x)`、`wasm/web_platform/e2e/`、`wasm/web_platform/fixtures/`：单测、浏览器测试与示例工程。
-- `@mujoco/mujoco`：作为默认单线程构建输入；`wasm/dist/*` 未手工修改。
-
-## Reuse
-
-- `wasm/demo_app/app.ts`：复用 `loadMujoco()` 初始化、`mjv_updateScene` 场景提取、Z-up 相机、固定仿真时长步进、矩阵同步和确定性释放思路；现有 `getBufferGeometry` 仅覆盖 plane/sphere/capsule/box/cylinder/ellipsoid，mesh 与贴图需补齐，且不可直接复制其全局 `app`/DOM 写法。
-- `wasm/demo_app/vite.demo.config.ts`：复用 `root`、相对 `base`、独立输出目录和开发响应头模式；MVP 单线程不依赖 COOP/COEP。
-- `wasm/tests/bindings_test.ts`：复用 `FS.writeFile/unlink`、`MjModel.mj_loadXML(path)`、`MjVFS.addBuffer`、带外部 OBJ 的加载测试以及 `finally + .delete()` 生命周期范式。
-- `@mujoco/mujoco` 类型：使用 `MjModel`/`MjData` typed-array 视图、named accessor、`MjvPerturb` 与 `mjv_applyPerturbForce` 等 API；避开 bool typed-memory-view 的绑定限制，并显式删除 accessor。
-- `doc/overview.rst`、`doc/modeling.rst`、`doc/APIreference/functions_override.rst`：MuJoCo 原生 `mj_loadXML` 可解析 MJCF 与 URDF，VFS 可容纳 XML/include、STL、PNG 等资源，因此 URDF 不另做平台侧转换。
-- 参考站点仅复用信息架构理念：本地导入、3D 视口、关节树/属性与控制面板；MVP 不复刻其编辑、格式转换或云端工具能力。

-
-### 0. 需求与架构定稿
-
-- [x] 确认 React + Zustand，采用 Vitest + Playwright；仅支持桌面版 Chrome/Edge/Firefox 最新两个大版本。
-- [x] 确认 MVP 输入格式为 MJCF/XML、URDF、文件夹和 ZIP；工程入口规则见后续步骤。
-- [x] 确认 MVP 使用主线程、单线程 WASM，不实现 Worker/MT。
-- [x] 明确参考站点只借鉴本地导入、工程树、中心视口、属性/控制面板的信息架构。
-- [x] 输出模块边界、数据流、错误模型和资源生命周期设计。
-
-### 1. 应用骨架与质量基线
-
-- [x] 创建独立平台应用入口、Vite 配置、TailwindCSS 和基础布局。
-- [x] 配置 TypeScript 严格检查、lint、单元测试与最小 E2E 测试。
-- [x] 配置 WASM 静态资源定位及开发/生产构建路径，保持 `base: './'` 以支持任意静态子路径。
-- [x] 验证本地静态 HTTP 服务器可正确提供 JS/CSS/WASM；不支持直接以 `file://` 打开，也不注册 service worker。
-- [x] 建立错误边界、加载状态、日志和中文可诊断错误展示。
-
-### 2. 工程导入与 MEMFS
-
-- [x] 定义 `ProjectFile`、虚拟路径、入口模型和资源清单模型。
-- [x] 支持单文件、多文件和目录拖放/选择，保留 `webkitRelativePath`；使用 ZIP 库在浏览器内解包 `.zip`，拒绝加密包、目录穿越和超限压缩内容。
-- [x] 统一 `/workspace/<project-id>/...` 虚拟根目录，规范化路径后通过 `FS.mkdirTree/writeFile` 写入 MEMFS；二进制文件保持 `Uint8Array`，文本 XML 使用 UTF-8。
-- [x] 入口规则：单个 XML/URDF 自动选中；多候选优先根目录 `model.xml`/`scene.xml`/唯一 `.urdf`，否则弹窗选择且按根元素 `<mujoco>`/`<robot>`标识类型。
-- [x] 使用 `MjModel.mj_loadXML(entryPath)` 让 MuJoCo 原生解析 MJCF/URDF 及相对资源；加载失败保留工程树并展示入口、资源路径和 MuJoCo 错误。
-- [x] 切换工程前按逆序释放会话对象，再递归删除 MEMFS 工作区；对文件数、单文件、解压总量设置可配置上限。
-- [x] 为 MJCF include + OBJ/STL/PNG、URDF + mesh、目录、ZIP、路径冲突和缺失资源添加测试夹具。
-
-### 3. MuJoCo 会话与仿真控制
-
-- [x] 封装 WASM 单例初始化和 `SimulationSession` 生命周期。
-- [x] 创建/销毁 `MjModel`、`MjData`，实现异常路径下的确定性释放。
-- [x] 实现播放、暂停、单步、重置、时间倍率、固定步长累积器。
-- [x] 实现 actuator 控件和 qpos/qvel/ctrl 等状态快照。
-- [x] 实现同步 `PhysicsAdapter` 接口并保持 UI 不直接持有 Embind 对象；Worker/message protocol 仅记录为后续扩展点。
-
-### 4. Three.js 可视化与交互
-
-- [x] 复用官方 demo 的 primitive 构建与 `mjv_updateScene` 方法，抽离为可测试的场景适配器。
-- [x] 支持 MuJoCo primitive；对 mesh 根据 `mjvGeom.dataid` 读取 `mesh_vert/face/normal/texcoord` 及地址/数量数组构建缓存的 `BufferGeometry`，并从 `tex_data/width/height` 创建纹理，覆盖材质和坐标/矩阵转换。
-- [x] 每帧同步动态 body/geom 位姿，避免重复分配临时对象。
-- [x] 实现 OrbitControls、相机复位、网格/坐标轴、灯光和 resize。
-- [x] 用 Raycaster 实现对象拾取、选中高亮及与属性面板联动，并维护 Three.js object → MuJoCo body/geom id 映射。
-- [x] 关节拖动仅对可直接编辑的 hinge/slide joint 开放：暂停仿真、按 joint axis 将拖动量写入对应 `qpos`、按 `jnt_range` 限位并执行 `mj_forward`；free/ball joint MVP 只读。
-- [x] 外力施加：选中动态 body 后以拖拽箭头显示方向/大小，在每个 `mj_step` 前通过 `MjvPerturb`/`mjv_applyPerturbForce` 施力，松开即清零，并提供强度刻度。
-- [x] 在模型切换/卸载时释放 geometry、material、texture、Embind 临时 accessor/vector 和渲染循环资源。
-
-### 5. 平台 UI 与状态管理
-
-- [x] 搭建参考站点式布局：顶部工具栏、左侧工程树、中心视口、右侧属性/控制面板、底部状态区。
-- [x] 实现 MJCF/XML、URDF、文件夹、ZIP 导入流程、入口选择、最近错误、加载进度与空状态。
-- [x] 实现播放/暂停/单步/重置/速度控件、基于 `actuator_ctrlrange` 的 actuator 滑杆，以及 joint 拖动/外力模式开关。
-- [x] 实现模型信息、body/joint/geom 属性检查器。
-- [x] 针对桌面宽屏提供可调整/折叠面板、中文文案、键盘操作和基本无障碍语义；手机和平板不在 MVP 验收范围。
-
-### 6. 性能、健壮性与交付
-
-- [x] 建立 FPS、step 耗时、模型规模和内存趋势监控。
-- [x] 验证大模型、资源缺失、无效 XML、重复加载和长时间运行。
-- [x] 对主线程 step 设置每帧预算与最大追赶步数，超预算时显示性能警告而非无限追帧；Worker/SharedArrayBuffer 留作后续版本。
-- [x] 完成生产构建、纯静态部署/离线使用说明、示例工程和用户文档。
-- [x] 更新本计划进度看板并记录遗留项。
-
-## Implementation Result
-
-- 平台代码：`wasm/web_platform/`；使用 `@mujoco/mujoco@3.11.0` 默认单线程入口。
-- 自动化结果：TypeScript、ESLint、10 个 Vitest 测试、5 个 Chrome Playwright E2E、生产构建均通过。
-- E2E 覆盖：单文件 MJCF、MJCF include + OBJ/STL/PNG、URDF + OBJ、中等规模持续步进/重复加载、无效模型错误保留；另用完整 Go2W ZIP 实测 ROS `package://`、重复 material 和 DAE 降级后可编译。
-- 静态服务验证：Python HTTP server 对 HTML 与 WASM 均返回 200，WASM MIME 为 `application/wasm`。
-- 依赖审计：`npm audit` 0 vulnerabilities。
-
-### 遗留验收项
-
-- Edge/Firefox 最新版本尚未在当前环境做人工交互验收。
-- 关节拖动、外力箭头与超大模型的视觉手感仍需结合真实机器人工程人工调参。
-- 当前构建有约 865 KiB JS chunk 的 Vite 体积警告；不影响 MVP，后续可按面板/Three.js 做代码分割。
-- E2E 的持续步进是秒级冒烟；发布前建议增加 30–60 分钟内存与稳定性 soak test。
-
-## Verification
-
-- 自动化：TypeScript 类型检查、单元测试、构建测试、浏览器 E2E 冒烟测试。
-- 导入：MJCF/URDF 与其 mesh/texture 相对引用可加载；缺失/冲突/非法路径给出可定位错误。
-- 物理：播放、暂停、单步、重置和 actuator 控制结果符合 MuJoCo 时间步；重复加载无悬挂循环。
-- 渲染：primitive/mesh 位姿与 `xpos/xquat` 一致，相机和选中交互稳定，窗口缩放正常。
-- 生命周期：连续切换模型和长时间仿真时，WASM/Three.js 资源无持续异常增长。
-- 浏览器：桌面版 Chrome、Edge、Firefox 最新两个大版本完成手工验收；不测试手机、平板和多线程模式。
-- 交付：生产构建可由本地静态 HTTP 服务器启动，`.wasm` MIME 与相对资源路径正确；明确 `file://` 不受支持。
-
-## Confirmed Decisions
-
-1. React + Zustand。
-2. MVP 支持 MJCF/XML、URDF、文件夹、ZIP；URDF 交由 MuJoCo 原生 loader 解析。
-3. 首版不做 XML 编辑、热重载和工程导出。

+
+机器人控制桥与训练桥是两个服务（分别 8766 / 8765），不共享令牌或训练执行能力。控制令牌只保存在页面内存；外控超时、隐藏、暂停、重载均撤销授权，必须手动重新允许。

-# MuJoCo Style Guide
-
-The MuJoCo codebase follows an internally consistent style that values
-compactness and readability. Please try to follow the style guide as closely as
-possible in your code contributions.
-
-### Scope of this guide
-
-Most of this guide involves C/C++ code. For Python, jump to the section
-[below](#python-code). For MuJoCo C/C++, code has three main categories:
-
-1. **C code:** MuJoCo's core codebase. It consists of public headers under
-`include/` and C source files and internal headers under `src/`. This style
-guide primarily concerns itself with this category.
-
-2. **Legacy C++:** Files under `src/user/` and `src/xml/`. These do not
-necessarily follow best C++ practices. We intend to gradually replace these with
-new code that follows the [Google C++
-style](https://google.github.io/styleguide/cppguide.html) over time.
-
-3. **New code:** This includes C++ files under `test/` and `python/` and C#
-files under `unity/`. Added by DeepMind engineers, this code adheres to the
-[Google style](https://google.github.io/styleguide/).
-
-### General principles
-
-Where any aspect of coding style is not explicitly spelled out in this guide,
-the following principle is followed:
-
-| Maximise consistency with the rest of the code. |
-| --- |
-
-If there is a contradiction between this guide and existing code, the guide
-takes precedence. Additional principles include:
-
-- Follow the [naming conventions](https://mujoco.readthedocs.io/en/latest/programming#naming-convention).
-- Be sparing with horizontal space: Try to keep lines short, avoid line-breaks
-  where possible.
-- Be generous with vertical space: Empty lines between code blocks are good.
-- Keep names short.
-- Inline comments are part of the code, treat them as such.
-- Use American English in comments and documentation.
-
-### Specific rules for C code
-
-Over time, this style guide will be expanded to cover most aspects of C
-programming in the MuJoCo codebase. In the meantime, it is usually enough to
-inspect existing code and try to follow its example.
-
-If there are any consistent coding patterns that are specific to the MuJoCo
-codebase but aren't mentioned in the guide, the guide should be expanded. If you
-spot such a pattern, feel free to send a PR to update the guide.
-
-#### Indentation
-
-2-space indents, using space characters rather than tabs.
-
-#### Line length
-
-Line length is 100 characters. In rare situations, like the collision table at
-the top of
-[engine_collision_driver.c](https://github.com/google-deepmind/mujoco/blob/c8ff7b3d341560e8cc33fbdcaffbcdbc4c32327c/src/engine/engine_collision_driver.c#L36),
-longer lines are allowed for readability.
-
-#### Comments
-
-MuJoCo makes generous use of short, one-line comments describing the code block
-just below them. They are considered an essential part of the code. Comments
-should be:
-
-- As succinct as possible, while maintaining clarity.
-- Preceded by an empty line, unless at the top of a block.
-- Uncapitalized and not terminated by a full-stop.
-
-A helpful heuristic regarding in-code comments is that the reader should be able
-to get a sense of what is happening in a function just by reading the comments.
-
-An exception to the third bullet point above are function declaration comments
-in public header files which are considered to be docstrings rather than code
-and are therefore capitalized and terminated by a full stop. These docstrings
-are required.
-
-#### Braces
-
--   MuJoCo uses
-    [attached K&R braces](https://en.wikipedia.org/wiki/Indentation_style#Variant:_mandatory_braces),
-    including for one-line blocks:
-
-    ```c
-    // transpose matrix
-    void mju_transpose(mjtNum* res, const mjtNum* mat, int nr, int nc) {
-      for (int i=0; i < nr; i++) {
-        for (int j=0; j < nc; j++) {
-          res[j*nr+i] = mat[i*nc+j];
-        }
-      }
-    }
-    ```
-
--   Brace-less single line statements are allowed with the exception of `return`
-    and `break` statements. For an example of this exception, inspect the
-    [`mjCModel` destructor](https://github.com/google-deepmind/mujoco/search?q=repo%3Adeepmind%2Fmujoco+filename%3Auser_model.cc).
-
--   Unattached braces are allowed in `if/else` blocks, when inserting an
-    explanatory comment above the `else`:
-
-    ```c

-    void mju_rotVecQuat(mjtNum res[3], const mjtNum vec[3], const mjtNum quat[4]) {
-      // null quat: copy vec
-      if (quat[0] == 1 && quat[1] == 0 && quat[2] == 0 && quat[3] == 0) {

-        mju_mulMatVec3(res, mat, vec);
-      }
-    }
-    ```
-
-#### Spacing
-
--   MuJoCo encourages judicious use of spacing around operators to promote
-    readability. For example below, note the lack of spaces around the
-    multiplication operator, and the aligning spaces in the second and fourth
-    assignments:
-
-    ```c
-    // time-derivative of quaternion, given 3D rotational velocity
-    void mju_derivQuat(mjtNum res[4], const mjtNum quat[4], const mjtNum vel[3]) {
-      res[0] = 0.5*(-vel[0]*quat[1] - vel[1]*quat[2] - vel[2]*quat[3]);
-      res[1] = 0.5*( vel[0]*quat[0] + vel[1]*quat[3] - vel[2]*quat[2]);
-      res[2] = 0.5*(-vel[0]*quat[3] + vel[1]*quat[0] + vel[2]*quat[1]);
-      res[3] = 0.5*( vel[0]*quat[2] - vel[1]*quat[1] + vel[2]*quat[0]);
-    }
-    ```
-
--   Spaces are required around comparison operators.
-
--   Spaces are not allowed around operators in array subscripts `[]` or in
-    variable initialisation in `for` loops. For example, inspect the
-    `mju_transpose` implementation above.
-
--   Two blank lines are required between function implementations in source
-    files.
-
-#### Variable declarations
-
-Historically the MuJoCo C codebase used exclusively C89-style variable
-declarations, with all stack variables pre-declared at the top of the function.
-We are in the process of migrating the code to the C99 convention of declaring
-variables at the narrowest possible scope. For example iterator variables in
-for-loops are mostly declared in the narrow scope, as in the `mju_transpose`
-example above.
-
-New code should use the C99 convention. When editing an existing function,
-please move existing variable declarations into local scope. Pull requests
-helping us to complete the migration are very welcome.
-
-### [Python code](#python-code)
-
-For Python code, run `pyink foo.py` to adhere to Google's
-[Python style guide](https://google.github.io/styleguide/pyguide.html). For
-sorting and cleaning imports, run `isort foo.py`. Both `pyink` and `isort` can
-be pip installed via `pip install pyink isort`.

-# MuJoCo Versioning
-
-MuJoCo uses custom semantic versioning from 3.5.0 onwards, see below.
-
-### The problem with Semantic Versioning
-
-The common definition of traditional [Semantic Versioning](https://semver.org/)
-is
-
-```
-1. MAJOR:  breaking changes
-2. MINOR:  new features
-3. PATCH:  bug fixes
-```
-
-With strict adherence to this definition, most MuJoCo releases are `MAJOR`. This
-is because MuJoCo has a very large API surface, especially when considering
-[MJCF](https://mujoco.readthedocs.io/en/stable/XMLreference.html) and the
-related
-[mjSpec](https://mujoco.readthedocs.io/en/stable/programming/modeledit.html)
-API. Furthermore, the numerical properties of physics state integration mean
-that despite being deterministic, numerical reproducibility across versions is
-almost guaranteed to
-[not hold](https://mujoco.readthedocs.io/en/stable/computation/index.html#reproducibility).
-
-## From 3.5.0 – semantic versioning
-
-From 3.5.0 onwards MuJoCo uses well-defined versioning with the following
-semantics.
-
-### MuJoCo versioning semantics
-
-```
-1. SUPERMAJOR:      breaking changes and/or significant new features
-2. MAJOR:           breaking changes, possibly new features
-3. MINOR_OR_PATCH:  new features or bug fixes
-```
-
-`MINOR_OR_PATCH` guarantees API backward compatibility, but may or may not
-introduce new features; to find out, read the
-[changelog](https://mujoco.readthedocs.io/en/stable/changelog.html), which will
-detail the nature of the changes. The changelog will also detail pure
-ABI-breaking changes, for example removing an unused attribute from a public
-struct. Such changes are considered MINOR. As explained
-[here](https://mujoco.readthedocs.io/en/stable/computation/index.html#reproducibility),
-numerical reproducibility is *never* guaranteed.
-
-Additionally:
-
--   `mj_versionString()` works as before, returning e.g. `"4.2.1"`.
--   `mj_version()` works as before, returning an integer. The corresponding
-    header constant `mjVERSION_HEADER` is calculated from the components as:
-
-    ```
-    mjVERSION = (SUPERMAJOR * 1e6) + (MAJOR * 1e3) + MINOR_OR_PATCH
-    ```
-
-    For example, 4.2.1 would be `4002001`.
-
-## Prior to 3.5.0 – no semantics
-
-Until 3.5.0, versioning was a sequence of increasing numbers with no
-well-defined semantic, with the exception of major versions introducing
-significant new features, like
-[3.0.0](https://mujoco.readthedocs.io/en/stable/changelog.html#version-3-0-0-october-18-2023)'s
-introduction of the JAX-based
-[MJX](https://mujoco.readthedocs.io/en/stable/mjx.html) branch. Additionally:
-
--   The function
-    [`const char* mj_versionString()`](https://mujoco.readthedocs.io/en/stable/APIreference/APIfunctions.html#mj-versionstring)
-    returns the version in the form of a string, for example `"3.2.7"`.
--   The function
-    [`int mj_version()`](https://mujoco.readthedocs.io/en/stable/APIreference/APIfunctions.html#mj-version)
-    returns an integer equal to the version digits concatenated,
-    for example for "3.2.7" we'd have `mjVERSION = 327`.

-TargetAddRpath
-----------------------
-
-Add support to RPATH for the specified targets
-
-.. command:: target_add_rpath
-
-  Add support to RPATH for the specified targets::
-
-.. code-block:: cmake
-    target_add_rpath(target1 target2 ...
-                     INSTALL_DIRECTORY install_directory
-                     LIB_DIRS dir1 dir2 ...
-                     [INSTALL_NAME_DIR [dir]]
-                     [DEPENDS condition [condition]]
-                     [USE_LINK_PATH])
-
-  This function setups the RPATH paths for the specified targets. The use of
-  RPATH allows to avoid using the (dangerous) environment variable
-  ``LD_LIBRARY_PATH`` (or equivalent on macOS) when installing  without absolute
-  paths.
-  By using RPATH the installation can be relocated as the linker will look for
-  (some of) the dependencies at run time.
-
-  The function has the following parameters:
-
-  Options:
-   - ``USE_LINK_PATH``: if defined, the function will set
-     ``INSTALL_RPATH_USE_LINK_PATH`` on all the specified targets, i.e. CMake
-      will automatically adds to the RPATH the path to all the dependent
-      libraries defined outside this project.
-
-  Arguments:
-   - ``INSTALL_DIRECTORY`` The directory where the specified targets will be
-     installed.
-   - ``LIB_DIRS`` list of directories to be added a search path to the RPATH.
-     Note that the relative path between ``INSTALL_DIRECTORY`` and these
-     directories will be added to the RPATH.
-   - ``INSTALL_NAME_DIR`` directory where the libraries will be installed.
-     This variable will be used only if ``CMAKE_SKIP_RPATH`` or
-     ``CMAKE_SKIP_INSTALL_RPATH`` is set to ``TRUE`` as it will set the
-     ``INSTALL_NAME_DIR`` on all targets.
-   - ``DEPENDS`` list of conditions that should be ``TRUE`` to enable
-     RPATH, for example ``FOO; NOT BAR``.
-
-  Note: see https://gitlab.kitware.com/cmake/community/-/wikis/doc/cmake/RPATH-handling
-  and  https://gitlab.kitware.com/cmake/cmake/issues/16589 for further details.

+
+## Key Code
+
+### 已有正确插入顺序
+`SimulationSession.singleStep/advance` 均执行：控制器 → 外力 → `mj_step`（`SimulationSession.ts:46-57`）。ONNX 动作必须沿用该位置，而不能在 React frame snapshot 后直接写 ctrl，否则会引入一物理步延迟和不稳定的渲染帧时序。
+
+### 参考部署契约
+Go2 deploy YAML 定义：
+- `step_dt: 0.02`，即策略 50 Hz；仿真步可保持 0.002 s，动作 hold 10 步。
+- observation 串接顺序和维数：`base_ang_vel(3), projected_gravity(3), velocity_commands(3), gait_phase(2), joint_pos_rel(12), joint_vel_rel(12), last_action(12)`，总计 **47 float32**。
+- action 为 12 维位置目标：`processed = raw * 0.25 + default_joint_pos`；默认位姿见 YAML lines 3-5/18-20。
+- joint 顺序不能取 MuJoCo ID 偶然顺序；部署 `joint_ids_map=[3,4,5,0,1,2,9,10,11,6,7,8]` 表示 RL 顺序与硬件/模型顺序存在显式重排。
+- ONNX 与参数是配套件：`params/deploy.yaml` + `exported/policy.onnx`（`State_RLBase.cpp:12-16`）。仅导入 `.onnx` 无法可靠解释 observation/action。
+
+### 最小文件级实现方案（建议，不修改）
+1. **新增独立策略层**：`src/policy/types.ts`, `OnnxPolicyRuntime.ts`, `Go2VelocityTask.ts`。
+   - `OnnxPolicyRuntime` 只负责 ORT session、输入/输出名称与 shape 校验、generation cancellation、dispose。
+   - `Go2VelocityTask` 固化首个 task 的 47→12 契约、命令/phase/lastAction、名称到 joint/actuator 的显式映射、PD 目标或 position actuator 输出。
+   - 不应把 ONNX 逻辑塞入 `PythonControllerRuntime`；其 Pyodide proxy 与同步函数假设完全不同。
+2. **`SimulationSession.ts`**：将单一 `pythonController` 最小泛化为互斥 controller slot，或新增 `onnxPolicy` 并在同一个 `runController()` 中互斥调度；load/remove/reset/dispose 复用 generation 防模型切换竞态。添加只读 observation helpers（按 joint/body/sensor 名称解析），避免 UI 从 snapshot 拼向量。禁用/异常时必须 `ctrl.fill(0)`、暂停并保留错误。
+3. **异步风险处理**：`onnxruntime-web` 的 `session.run()` 返回 Promise，不能直接 await 于当前同步 `advance()` while loop。最小侵入方案是“最新完成动作 hold”：到 50 Hz 时复制 observation 发起一次推理（仅允许一个 in-flight），后续物理步继续持有上次动作，完成后原子替换；首帧保持安全默认位姿而非零力矩。状态须显示 inference latency/overrun。若要求训练等价的严格每 20 ms 动作，则需把物理 loop 改为异步/worker，已非最小侵入。
+4. **`PhysicsAdapter.ts`**：接口新增 `loadOnnxPolicy(policyBytes, config)`, `setPolicyEnabled`, `setVelocityCommand`, `removePolicy`；MainThread adapter 只转发，模型 `releaseCurrent()` 自动 dispose。不要把 policy 写入 MuJoCo MEMFS，ORT 可直接吃 `Uint8Array`。
+5. **项目导入**：`importer.ts` 已保留任意扩展名，ZIP/目录中的 `.onnx/.yaml` 会存在 `manifest.files`；无需修改 `discoverEntries`（它只应发现模型）。在 App 中按配套目录约定寻找 `exported/policy.onnx` 及 `params/deploy.yaml`，首版更稳妥的是新增浏览器可直接解析的 JSON policy manifest；不要为 YAML 引入重量解析器后猜测任意训练配置。独立单文件导入应沿用 Python 的 upsert 流程，但 accept 改 `.onnx` 并施加专用上限。
+6. **依赖/构建**：`wasm/package.json` 加 `onnxruntime-web`；`vite.config.ts` 仿照 Pyodide 将 ORT wasm 文件复制到固定相对目录并设置 `ort.env.wasm.wasmPaths`，否则离线 `base:'./'` 构建容易 404。首版使用 wasm CPU 单线程，避免 WebGPU/COOP-COEP 扩大范围。
+7. **UI**：新增 `PolicyPanel.tsx`，插在 `SidebarPanel.tsx:32` 的控制 tab，与 Python 控制器并列；展示模型/config、47×12 shape、50 Hz、启停、速度 x/y/yaw、推理耗时/错误。`App.tsx:40,55,72-77,104` 按现有 controller 状态模式增加 policy 状态及 callbacks；加载另一控制器时明确移除/禁用前一个，不能二者同时写 ctrl。
+8. **首个 Go2-W 任务边界**：参考仓库提供的是 **Go2 12-DOF** velocity policy，不是 Go2-W policy；Go2-W 多四个轮关节。首版可把 12 个腿关节按该 policy 控制、轮 actuator 固定阻尼/零速，仅称“Go2-W 腿式站立/速度实验”，不能宣称与训练分布一致。真正轮式平衡/速度需要 Go2-W 专属训练导出（observation/action 很可能含轮速和 16 维动作）。
+
+## Architecture
+浏览器文件 → `ProjectManifest.files`（二进制 ONNX 已保留）→ `App` 选择配套 policy/config → `PhysicsAdapter` → `SimulationSession` 拥有 policy runtime。每个 MuJoCo 子步前 task 从 `MjData` 组 observation；每 0.02 s 异步提交 ONNX，完成输出经 scale/offset、显式 joint mapping 和限幅后成为 held action；物理 loop 每步应用 held action。snapshot 仅向 UI报告状态，不作为 observation 数据源。
+
+## 观测/动作风险与严重度
+- **blocker**：参考资产无 Go2-W ONNX，且仓库参考目录下 Go2 velocity 的 `exported/policy.onnx` 实际不存在；不能验证 input/output 名或数值一致性。
+- **blocker**：Go2 12-DOF policy 与 Go2-W 16 actuator 拓扑不匹配。若按 `model.njnt/nactuator` 顺序拼接会 shape 错误或静默错控。
+- **high**：`projected_gravity` 必须是重力单位向量由世界系旋到 body/IMU 局部系。MuJoCo `xquat` 为 wxyz；符号、quat inverse、IMU 安装姿态任一错误都会使策略立刻摔倒。加速度计并不等价于无噪声 projected gravity。
+- **high**：`base_ang_vel` 需 body/local frame；直接使用 free joint `qvel[3:6]` 或 gyro sensor前必须确认 MuJoCo sensor frame与训练定义一致。
+- **high**：`joint_pos_rel = q-default`，joint_vel 和 action 都必须是 YAML 的 RL 顺序；四足 FL/FR/RL/RR 次序在当前手写 Go2-W controller 与 deploy map 中并不天然一致。
+- **high**：输出是 normalized action，不是 torque；必须 scale+offset 后交给 position actuator/PD。当前 `setActuator` 只写 ctrl，URDF 自动生成的是 motor（`PhysicsAdapter.ts:68`），因此若直接写位置值会被当 N·m。需要 task 内 PD torque，或为该 task 构造 position actuator。
+- **medium**：gait phase 是 0.6 s 周期的 sin/cos，但应确认零点、sin/cos 顺序以及站立零命令时是否冻结；YAML 没编码完整函数语义。
+- **medium**：异步 ORT latency 若超过 20 ms 会跳过策略 tick；必须统计 dropped/late inference，且避免并发堆积。
+- **medium**：reset 应同时清 lastAction、phase、in-flight generation 和 held action；否则旧 Promise 可污染新 episode。
+- **medium**：导入不可信 ONNX 可能造成大内存/计算消耗；现有 128 MiB 文件上限不足以约束 tensor shape/运行时内存。
+
+## 测试建议
+1. `src/policy/Go2VelocityTask.test.ts`：固定 qpos/qvel/quaternion/command，逐元素断言 47 维顺序、dtype、projected gravity、phase、joint reorder；固定 raw action 断言 `*0.25+offset` 和 actuator 映射。
+2. `src/policy/OnnxPolicyRuntime.test.ts`：mock ORT，覆盖 input/output shape/name 错误、NaN/Inf、single-flight、超时/overrun、generation cancellation、dispose；用极小 identity ONNX fixture 做一次真实 wasm smoke test。
+3. 新增 `SimulationSession.test.ts`（当前该核心类无测试）：mock MainModule 验证 controller 在 `mj_step` 前执行、50 Hz decimation、held action、reset/disable/error 清 ctrl、Python/ONNX 互斥、模型切换后旧推理无效。
+4. `PhysicsAdapter` contract test：load/remove/dispose 转发及失败后 workspace/runtime 都释放。
+5. `importer.test.ts`：ZIP/目录保留 `.onnx` 与 config、路径规范化、重复/超限拒绝；entry discovery 不把 ONNX 当模型。
+6. `PolicyPanel.test.tsx` + `SidebarPanel` 测试：导入、启停、命令范围、shape/错误展示、另一控制器启用时互斥。
+7. Playwright：导入 Go2-W 工程+fixture policy，启用后推进若干秒，断言页面不崩、policy 状态与命令变化；数值验收应另做离线 golden trajectory（相同初态前 N 次 observation/action 与 Python/ORT reference 对齐），容差逐元素约 `1e-5`，并检查 base height/倾角安全阈值。
+8. 常规命令：`npm run typecheck:platform`, `npm run lint:platform`, `npm run test:platform`, `npm run build:platform`, 最后 `npm run test:e2e:platform`。
+
+## Start Here
+先打开 `wasm/web_platform/src/simulation/SimulationSession.ts:44-93`：这是唯一能保证 observation 采样、控制输出和 `mj_step` 顺序正确，并统一 reset/error/dispose 语义的位置。
+
+## Residual Risks
+- 未获得 Go2-W 专属 ONNX 与导出 metadata，无法完成真实 shape/name/golden 验证。
+- unitree_rl_mjlab 的 YAML 说明字段顺序与缩放，但 gait phase、frame convention 等函数语义仍需用实际导出/运行器确认。
+- 主线程异步 inference 的 held-action 方案是最小侵入折衷，不提供硬实时或训练环境严格等价。

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a

+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+# 本机机器人控制桥接
+
+独立于 `training_server` 的实时数值接口。默认监听 `127.0.0.1:8766`；不导入 LeRobot、PyTorch 或训练任务，不执行代码、Shell 或服务器文件路径。
+
+## 启动
+
+从仓库根目录执行（Python 3.12）：
+
+```bash
+source .venv/bin/activate
+python -m pip install -e ./control_bridge
+python -m mujoco_control_bridge
+# 或 npm run control-bridge
+```
+
+未设置 `MUJOCO_CONTROL_TOKEN` 时，服务生成至少 256 bit 随机 token，只在启动终端显示一次。也可通过该环境变量提供自己的 token（16–4096 个可打印 ASCII 字符，不含空白）。`--port 0` 自动分配端口，仅测试需要；不能配置非回环监听地址。
+
+1. 在本机 HTTP 工作台加载受支持的机器人，显式选择 profile 并通过编译校验。
+2. 在“控制台 → 开源项目 / 外部控制”填写地址和 token，连接桥接。
+3. 播放，然后点击“允许外部控制”。接管会停止 Python/ONNX、锁定 1×并禁止冲突写入。
+4. 在另一终端给 SDK 设置相同 token（不要把 token 放进 URL、源码或命令历史）：
+
+```bash
+read -rsp '控制 token: ' MUJOCO_CONTROL_TOKEN; echo
+export MUJOCO_CONTROL_TOKEN
+export MUJOCO_CONTROL_ENDPOINT=http://127.0.0.1:8766
+```
+
+## 通用 Python SDK
+
+客户端路径仅使用 Python 标准库；HTTP 不使用环境代理，也不跟随重定向。接口不依赖 LeKiwi 的通道名称或数量。
+
+```python
+import os
+import time
+from mujoco_control_bridge import SimRobotClient
+
+with SimRobotClient(os.environ["MUJOCO_CONTROL_ENDPOINT"]) as robot:
+    descriptor = robot.describe()
+    values = {
+        channel["id"]: min(channel["max"], max(channel["min"], 0.0))
+        for channel in descriptor["actionChannels"]
+    }
+    start = time.monotonic()
+    for i in range(90):
+        measured = robot.get_observation()  # 实际状态，不是目标回显
+        accepted = robot.send_action(values)  # 物理步后确认，包含已接受的限幅目标
+        time.sleep(max(0, start + (i + 1) / 30 - time.monotonic()))
+```
+
+通用 SDK 要求提交完整通道集合；部分动作的保持/默认语义由具体插件处理。`robot.reset()` 返回新 `modelEpoch` 的暂停观测，并清除租约；必须在浏览器重新播放、授权，再连接。`is_connected` 不是永久健康承诺：距成功动作超过 500 ms 会在本地失效。
+
+## 边界与故障处理
+
+- HTTP Bearer token；WS 首帧认证。校验本机 Host/Origin，拒绝查询字符串 token、远程页面和未经认证的预检/连接。
+- 一个浏览器后端、一个 Python 写入者；读取状态不取得写权限。不能自动抢占已有控制者。
+- 64 KiB 帧/请求、每租约至多 100 动作/秒、8 个在途 RPC、一个最新待应用动作；旧目标被替换时返回 `SUPERSEDED`，不会堆积无限队列。
+- 浏览器注册/认证有绝对超时；1 秒 RPC 确认期限、500 ms 动作/观测新鲜度边界。同序号心跳不刷新观测年龄。
+- 暂停、断连、进程崩溃、重载、页面隐藏、冻结超时均撤销授权。轮目标归零、臂/夹爪保持实测姿态，并暂停外控仿真；**不是把所有位置伺服置零**。
+- 回到页面或重新连接不会恢复旧命令。先检查错误、恢复关节限位，再播放/授权。
+- 无 HTTPS/WSS、跨机器访问、锁步、图像流、LeRobot 数据集或训练 API。不要使用端口转发或反向代理扩大此 V1 的信任边界。
+- 浏览器控制 token 仅在页面内存；不写入 `localStorage`/`sessionStorage`、工程导出或应用日志。拥有 token 的本机进程仍被视为可信控制者。
+
+测试：`python -m unittest discover -s control_bridge/tests -v`。完整消息结构、错误码和扩展点见 [机器人接口](../docs/robot-interface.md)；LeRobot 用法见 [LeKiwi 示例](../examples/lekiwi/README.md)。

+# Web 仿真控制脚本
+
+该目录存放可由 MuJoCo Web 平台“控制 → Python 控制器”直接导入的可信本地脚本。
+
+## Go2-W 平衡控制
+
+文件：`go2_w_balance.py`
+
+使用条件：
+
+1. 可导入 `/home/cen/Embodied_Workspace/unitree_ros/robots/go2w_description/` 文件夹/ZIP，或 Unitree 官方 `/home/cen/Embodied_Workspace/unitree_mujoco/unitree_robots/go2w/` MJCF 工程；
+2. 使用 URDF 时选择“转换为 MJCF”和“浮动基座”；
+3. 使用 URDF 时勾选“为关节添加驱动器”和“添加传感器”，平台会在浮动基座注入6轴 IMU；
+4. 模型加载后进入“控制 → Python 控制器”，导入本文件；
+5. 点击“加载脚本”或直接导入后，点击“启用”，再播放仿真。
+
+控制器兼容两套命名：
+
+- Body：官方 MJCF 的 `base_link` 或 URDF 转换模型的 `base`
+- 腿关节：`FL/FR/RL/RR_{hip,thigh,calf}_joint`
+- 轮关节：官方 `*_wheel_joint` 或 URDF 转换后的 `*_foot_joint`
+- actuator：官方 `FL_hip`/`FL_wheel` 风格，或平台生成的 `<joint-name>_motor`
+- 6轴 IMU：`imu_gyro`（三轴角速度）和 `imu_acc`（三轴加速度）
+
+脚本在原地站立和 IMU roll/pitch 调平基础上，实现平台 Python SDK 的标准基本移动指令：停止、前进、后退、左转、右转和原地起跳。加载并启用脚本后，可在“基本移动指令”面板直接操作。前后移动采用四轮速度闭环；转向采用前轮主导、后轮限幅的左右差速，减小后腿 hip 关节摆幅；起跳采用“下蹲—爆发伸腿—腾空收腿—落地准备—恢复”的一次性轨迹。
+
+控制脚本可选定义同步函数 `command(name, state)` 接收指令。当前标准指令名为：
+
+- `stop`
+- `forward`
+- `backward`
+- `turn_left`
+- `turn_right`
+- `jump`
+
+其中移动/转向指令会持续生效，直到收到另一条移动指令或 `stop`。`stop` 会在轮速降为零后继续执行带积分补偿的站立姿态恢复，使机身自动回正。`jump` 是一次性原地起跳指令，会先切换到 `stop`。控制器在下蹲阶段保持完整重心补偿，爆发阶段以小腿竖直推力和轮毂反作用力矩抑制后仰，并记录起跳点；落地接触后会沿机身前向轴自动收回水平漂移。控制器必须确认位置、机身高度、姿态和角速度重新稳定，才会执行下一次已排队的起跳，避免连续起跳逐步后仰。不同接触参数、质量或初始姿态下，可调整 `NOMINAL`、`KP_FINAL`、`KD`、`DRIVE_SPEED`、`DRIVE_ACCELERATION`、`TURN_RATE`、`TURN_ACCELERATION`、`WHEEL_VELOCITY_KP` 和 `MAX_WHEEL_TORQUE`。速度指令采用斜坡限制，避免轮毂力矩阶跃导致机身后仰；起跳会等待轮速和重心稳定，随后以小腿满力矩爆发伸展，并在腾空阶段主动收腿和持续控制俯仰。

+# LeKiwi 本机模型服务
+
+独立于训练、控制桥和 MuJoCo；只接收结构化状态并返回经校验的计划/判定，不执行物理步进或模型给出的代码。默认 `127.0.0.1:8768/api/decision/v1`。
+
+## 网站模式
+
+`python -m decision_server --website-origin https://cadworld-sim.robotquan.com` 启动独立同源网站模式，不打印服务令牌、不自动发现 `.env`。当前生产另显式指定 `--website-key-file /run/secrets/model-keys.env --website-budget-file /var/lib/cadworld/budget.sqlite`，按两项固定变量读取站长授权的 DeepSeek flash/Jev 1.13 密钥；启动不推理。密钥为服务器受保护只读文件，不打包到镜像/静态站点，不发送到浏览器。
+
+每访客任务、取消和限额仍独立，只有固定模型凭据由服务器提供；全站 60 次/小时、600 次/24h 的上游调用预留记录持久化，进程重启/换 Cookie 不重置。共享模式禁用公开配置修改、模型目录、连接测试及订阅接口；本地模式与非共享模式的原连接/官方订阅能力保留，无自动回退。
+
+新增 `/command`：DeepSeek 结构化理解单个动作、Jev 检查意图；距离/角度/字段/方向与单位再由代码检查。只返回受限语义，不返回代码/执行器写入。实际驱动与物理成功在浏览器判断，取消身份覆盖整条双模型请求。见 [网站 API](../docs/website-api.md)、[部署手册](../docs/website-deployment.md) 和 [当前实测](../docs/website-hosted-control-2026-09-24.md)。
+
+## 语言控制面板：本地推荐启动方式
+
+本地与网站统一为“机器人语言控制”，界面不再填写 token/密钥或配置模型。使用现有同源会话模式，密钥文件由操作者准备，包含 `DEEPSEEK_API_KEY` 与 `OPENROUTER_API_KEY`，不进入前端：
+
+```bash
+source .venv/bin/activate
+python -m decision_server --website-origin http://127.0.0.1:5173 --website-dev \
+  --website-key-file /absolute/path/model-keys.env \
+  --website-budget-file "$HOME/.local/state/mujoco-decision/language-budget.sqlite"
+# 另一终端；浏览器必须使用与 website-origin 完全一致的地址
+npm run dev -- --host 127.0.0.1
+```
+
+Vite 本地/网站模式均代理 `/api/decision/v1`。换端口时同步修改 `--website-origin`；代理目标默认 `127.0.0.1:8768`，可用服务器环境变量 `CADWORLD_DEV_API` 修改。没有可用模型服务会报错，不自动转 mock。旧 Bearer 服务仍供程序化客户端使用，不能直接替代此面板的同源服务。
+
+## 旧 Bearer 客户端启动（非新版面板）
+
+```bash
+source .venv/bin/activate
+# 当前环境已有 aiohttp 3.14.3，无需升级 MuJoCo/训练依赖。
+# 新环境可单独安装：python -m pip install -r decision_server/requirements.txt
+npm run decision-server
+```
+
+控制台打印本进程专用服务令牌。旧程序化客户端需要 Bearer 令牌；它不是模型 API Key。默认仅允许工作台 `localhost/127.0.0.1:5173/4173`，其他本机测试端口通过 `--origin http://127.0.0.1:4176` 显式允许。
+
+用户已批准本项目使用 `.env` 中的两项凭据。按需显式启用：
+
+```bash
+npm run decision-server -- --openrouter-env .env --deepseek-env .env
+```
+
+- OpenRouter：只读取 `OPENROUTER_API_KEY`，仅配置 Jev `typesafe/jev-1.13` / `https://openrouter.ai/api/alpha/decisions`。
+- DeepSeek：只读取 `Deepseek_API_KEY` / `DEEPSEEK_API_KEY`，配置用户再次确认的 `deepseek-flash` / `https://api.deepseek.com`，使用 Responses 协议。
+- 加载器不 source/eval、不展开环境变量、不读取其他变量值作为配置、不接受文件中的 URL/model，不自动发请求。重复目标变量、坏格式或缺密钥明确报错。没有指定参数时不自动扫描 `.env`。
+- 密钥仅服务内存；无 dotenv/云 SDK/系统钥匙串隐式回退。文件本身由用户管理，服务不会改写；`.gitignore` 已排除 `.env`。普通连接也可通过受保护 HTTP 接口配置，不在浏览器持久化。
+
+默认非秘密连接元数据在仓库外 `~/.local/state/mujoco-decision/connections.json`（0600）。重启后普通连接需要重新提供密钥；换地址必须重新提供密钥，不携旧密钥跨域。远端只允许 HTTPS，HTTP 仅字面回环地址/localhost；不跟随重定向、不继承代理环境配置。
+
+## 协议与限制

+| `/connections`                                    | PUT  | `role,protocol,baseUrl,model,apiKey`；role 为 llm/jev       |
+| `/test`                                           | POST | `{role}`，显式连接测试；API 会计费，Codex 只做离线能力门禁  |
+| `/plan`                                           | POST | `{observation,instruction,remaining}`                       |

+| `/codex/status`, `/codex/models`, `/codex/limits` | GET  | 官方账号状态、模型目录、原始数值额度窗口                    |
+| `/codex/login`, `/codex/cancel`, `/codex/logout`  | POST | 空对象；官方登录 URL 仅此响应交给浏览器，不能保存/日志导出  |
+
+所有路由均有精确 Host、Origin、Bearer 校验；没有任意 URL/RPC 转发、文件读取或 shell 接口。请求体上限 64 KiB，响应上限 256 KiB；上游 HTTP 45 秒，服务推理 60 秒，必要的进程中断/回收有独立短期限。每服务同一时刻仅一个推理/连接测试；取消、配置变更和断连令旧请求无效。
+
+每回合最多 3 次 LLM（初始 + 2 次重规划）、60 次 Jev，最多 20 分钟墙钟；同一服务最多 120 次/小时，最多保留 32 个回合预算记录。失败/取消也计数，重复/过期 requestId 不可重新执行。没有网络自动重试、静默模型替换或规则降级。连接测试使用独立预算桶，也计全局预算。
+
+LLM 显式选择 `responses` 或 `chat-completions`。两者都要求结构化 JSON；不兼容时明确报错，不悄悄降级。Jev 显式选择 `typesafe` 或 `openrouter-decisions`，两者均是 `state/questions/answers`，不是聊天接口。保留服务选择，不根据概率私自重排。只返回经过验证的计划/判定及数值 usage；OpenRouter 返回的 cost 是服务报告值，不是硬编码估价。DeepSeek 未返回费用时仅显示 token，不能伪造金额。
+
+## 官方 Codex：实验性、逐模型门禁
+
+仅支持已验证的 **codex-cli 0.147.0**；不自动安装/升级，不使用私有 ChatGPT 接口，不把订阅凭据传给 API Base URL。
+
+- 每进程在仓库外创建独立临时 HOME/CODEX_HOME/cwd，关闭项目指令、shell、code mode、插件、apps、hooks 等；拒绝继承的 MCP/hooks/notify 执行配置。仅会话 OAuth，退出进程即丢失，不读取用户全局登录。
+- 随代码附带匹配版本的模型目录，仅缩减工具能力和替换提示词，保留模型标识/可见性/账号范围。来源和许可见 `THIRD_PARTY_NOTICES.md`。隐藏/退役的 gpt-5.4 不是当前默认或通关替身。
+- 每个选定模型首次使用前运行原生 CLI 离线门禁：仅连接私有回环假 Responses 服务，验证不暴露工具；强行注入 apply_patch、shell_command、exec_command、view_image 必须分别返回 unsupported，并验证未写文件。失败、超时或版本不符立即拒绝规划。
+- 通过 `account/login/start(type=chatgpt)` 登录、`account/read` 确认、`model/list` 选择；模型目录不是实际账号权限/额度的承诺，上游仍可拒绝。真实调用必须已登录且逐模型门禁通过。
+- `thread/start(ephemeral)` + `turn/start(outputSchema)`；只接受当前 thread/turn 的最终合法计划，工具输出/未知项拒绝。取消走精确 `turn/interrupt`；失败则终止进程，结束后 unsubscribe，释放线程资源。
+- `account/rateLimits/read` 只展示官方数值窗口；不推算订阅美元费用。额度不足、登录失效、型号/请求被拒绝均明确错误，不切换付费 API。
+
+本机 5 个可见模型的离线门禁、真实 stdio 假推理的结构化计划与 unsubscribe 已通过。**未完成真实 ChatGPT 登录/订阅推理验收**；需要用户浏览器交互。
+
+## 测试与已知验证范围
+
+```bash
+source .venv/bin/activate
+npm run test:decision-server
+# 额外：本机固定版本 CLI，无账号登录/远端推理
+DECISION_CODEX_SMOKE=1 npm run test:decision-server
+```
+
+常规 CI 仅本地假服务和 mock，不需要凭据/CLI/GPU/机器人资产；原生 Codex 用例显式启用。共享 `contracts/lekiwi-agent-v1.schema.json` 的 Python/TS 有限子集校验均拒绝额外字段、非有限数、非法对象/技能和跳前置条件计划。
+
+真实单请求证据（输入为**合成契约夹具**，不是实时物理采样，也不是完整抓放闭环）：
+
+- `build/lekiwi-agent/openrouter-jev-smoke.json`：Jev 初始状态判定通过，服务报告 $0.00004263。
+- `build/lekiwi-agent/deepseek-plan-smoke.json`：最初指定的 `deepseek-v4.1-flash` 未出现在官方模型列表，没有发起该型号推理。
+- 经用户确认改为 `deepseek-flash` 后，`build/lekiwi-agent/deepseek-flash-plan-smoke.json`：11 阶段规划及所有前置条件通过；836 输入 / 1608 输出 token，没有费用字段。
+- Codex 最初门禁把省略的 tools 当作失败，保留 `current-model-first-gate.json`；修正为允许“省略或空数组”（不接受非空工具）后，5 个可见模型及 4 类注入全部通过，见 `build/lekiwi-agent/codex-capability/`。省略 tools 的 API 语义是不提供工具，不是忽略已有工具。
+
+后续主工作台已完成两次真实 DeepSeek `deepseek-flash` + OpenRouter Jev 物理回合；最新为 1 次规划、11 次判定、实际持物搬运 0.593727 m，详见 [任务验收](../docs/lekiwi-agent.md)。证据保存在 `build/e2e/lekiwi-agent-final-gates/`。未保存的配置草稿会禁用任务/测试，避免仍调用旧付费配置。真实 ChatGPT 隔离登录已确认，订阅推理未运行；用户已接受以 DeepSeek + Jev 回合完成本次验收。临时登录会话已关闭，不能把登录/离线门禁当成订阅推理资格证明。

+    wherever such third-party notices normally appear. The contents
+    of the NOTICE file are for informational purposes only and

+6.  Trademarks. This License does not grant permission to use the trade
+    names, trademarks, service marks, or product names of the Licensor,
+    except as required for reasonable and customary use in describing the
+    origin of the Work and reproducing the content of the NOTICE file.
+
+7.  Disclaimer of Warranty. Unless required by applicable law or
+    agreed to in writing, Licensor provides the Work (and each

+    implied, including, without limitation, any warranties or conditions
+    of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+    PARTICULAR PURPOSE. You are solely responsible for determining the
+    appropriateness of using or redistributing the Work and assume any
+    risks associated with Your exercise of permissions under this License.

+    the Work or Derivative Works thereof, You may choose to offer,
+    and charge a fee for, acceptance of support, warranty, indemnity,
+    or other liability obligations and/or rights consistent with this
+    License. However, in accepting such obligations, You may act only
+    on Your own behalf and on Your sole responsibility, not on behalf
+    of any other Contributor, and only if You agree to indemnify,
+    defend, and hold each Contributor harmless for any liability
+    incurred by, or claims asserted against, such Contributor by reason
+    of your accepting any such warranty or additional liability.
