+### LeKiwi 语言控制、内置机器人与网站嵌入
+
+- 将 v1.0.1 之后的网站托管模型、自然语言动作/搬运、内置 LeKiwi 与双摄像头、部署与指定域名 iframe 嵌入变更归档为 `v1.0.2`，同步 npm 包与锁文件版本。正式内置机器人保留来源与许可证，不纳入密钥、个人模型、构建产物或测试日志；真实 v2 云模型抓放仍待单独授权验收。
+- 本次提交前复验：TypeScript 检查、17 文件/120 项定向前端测试通过；决策服务 44 项通过、3 项可选门禁跳过。已通过的公网应用及 iframe 检查各 3/3，本次不重复付费调用或部署。提交清单检查排除运行凭据与产物，内置 ZIP 的 SHA-256/许可证核验通过。
+
+- 网站 iframe 来源白名单新增 `https://cadworld.robotquan.com`：移除冲突的 `X-Frame-Options: DENY`，CSP `frame-ancestors` 仅允许本站及该来源，不使用通配符；保持既有 Strict/HttpOnly/Secure Cookie、Origin/CSRF 校验和 CORS 限制。已热更新线上配置，后端未重启；公网 iframe 正向/拒绝与会话验证 3/3 通过，不调用付费推理。同事实际页面尚未接入验收，示例与配置备份见 `docs/website-embedding.md`。
+
+- 网站已发布 `20260924T065821Z-language-v2`，前后端同步上线，回滚版本为 `20260924T052730Z-dual-camera`。打包白名单与 Docker 镜像补齐 v2 任务/场景契约；发布脚本新增无网络、无密钥挂载的导入/目标解析预检，失败不切换线上。公网非付费检查 3/3 通过：预设加载、文字指令/本地停止、双相机、Python 与会话/配置保护正常；线上 HTML 哈希匹配构建产物。既有服务器密钥/持久预算身份不变，验证未发起付费模型调用；真实 v2 推理待验收。详见 `docs/lekiwi-language-v2-release.md`。
+
+- LeKiwi 语言控制 v2：本地/网站统一极简文字面板，支持显式预设加载、A/B 命名目标及支撑区域内的 XY/XYZ 世界坐标。执行不重置方块、不移动台面；保留移动/转向、地图/RL 和双相机，模型配置改由同源后端托管。
+- 控制分层为 LLM 意图/计划 → Jev Choice/Noul/Score → 参数化 IK/接近/抓放执行 → 原 MuJoCo 伺服。增加跨阶段统一任务预算、严格版本/目标/单位验证、支撑面绑定、净空与接触保护；评分仅供诊断，物理成功与硬安全不可由模型覆盖。保留旧 v1 基线与 API 夹具。
+- 精简验收：主工作台真实 WASM＋假 HTTP 上游连续搬到 B 区及自由坐标成功，有效搬运 0.728882/0.241201 m、最终误差 7.54/8.92 mm；scratch 标定、真实夹爪锁开失败、旧 v1 种子0、网站移动/转向/停止通过。实现阶段定向测试及双构建通过，未跑全仓/训练、未调用真实模型；随后网站已部署（见上述发布记录）；详见 `docs/lekiwi-agent.md`。修复空工作台加载机器人时控制面板因 DOM 分支变化卸载、取消正在进行的预设加载的问题。
+
+- 补齐 LeKiwi 双摄像头：前置固连 `Camera-Model-v3`，腕部固连 `Camera-Model-v3-1`，分别依据源 URDF/STL 设定独立光心与旋转。左下角支持前置/腕部视角切换，默认前置；仅切换显示，不重载模型、不推进物理、不改变控制权。多相机转换幂等、仅添加一套 IMU；补充双镜头源坐标、显示切换、真实 WASM 导出与腕部/底盘随动回归。发布 `20260924T052730Z-dual-camera`，655 项单测、公网双视角 6/6、原非付费回归 2/2 和独立真实 WASM 随动验证 1/1 通过，未调用付费模型。
+
+- 修复 URL 自动导入 LeKiwi 的摄像头误挂支架、偏移与侧向朝向：改为固定在 `Camera-Model-v3` 前置镜头光心，依据原 URDF/STL 变换设置 wxyz，保留朝前/向上 10° 的 CAD 安装姿态并避免自身遮挡；不改原 ZIP 或动力学。通用转换增加归一化四元数支持，显式挂载点不存在时拒绝静默换点。新增源 URDF 光心/光轴、非法四元数与真实 WASM 导出相机世界位姿回归。发布 `20260924T050135Z-camera-fix`，648 项单测、公网自动导入 6/6 与原非付费回归 2/2 通过，未调用付费模型。
+
+- 新增 URL 参数 `robot=lekiwi-v1`：从服务器下载内置 LeKiwi ZIP，校验后自动选择 URDF/profile 并导入真实 WASM，跳过手动上传与配置弹窗，默认暂停且不触发付费模型。内置包原样保留许可/来源，Vite 输出带内容哈希的静态资产；无参数不下载，拒绝任意地址/未知/重复参数，下载失败可恢复手动导入。新增 15 项单测和 6 项浏览器回归，覆盖开发态 StrictMode、刷新与生产构建；发布为 `20260924T043358Z-builtin-robot`，640 项前端单测、公网自动导入 6/6 及原非付费回归 2/2 通过，公网 ZIP 哈希与原包一致。接入文档与验收记录见 `docs/builtin-robots.md`。
+
+- 按用户最新要求改为服务器内置 DeepSeek `deepseek-flash`＋OpenRouter Jev `typesafe/jev-1.13`，网页移除密钥/模型/订阅配置。仅两项授权变量经 SSH 输入配置到服务器 0400 只读文件，不随静态站点/镜像/Git 发布；增加跨会话、跨容器保留的 60 次/小时、600 次/24h 全站调用限额及配置锁定。
+- 网站新增自然语言前进/后退（0.01–1 m）、左/右转（1–180°），方向不明先询问。DeepSeek 结构化理解＋Jev 意图检查；当前位姿闭环驱动、物理误差验收，无重载/瞬移或独立时钟；停止/隐藏/迟到响应/控制权与碰撞、姿态、时限保护保留。本地模式不变。
+- 发布 `20260924T035108Z-hosted`：625 前端/43 后端测试及本地工作台回归通过，假上游＋真实 WASM 移动/转向/中断/抓放通过，公网非付费 2/2。真实模型前进约 0.496631 m、左转约 89.828887° 成功；附带抓放在松开后被 Jev 选择 stop，未完整通过，未重试或跳过安全判定。本轮实际 4 次 DeepSeek＋13 次 Jev，测试会话已销毁；详见 `docs/website-hosted-control-2026-09-24.md`。以下记录为此前 BYOK 阶段历史，不代表当前界面。
+
+- 经用户授权完成一次公网 DeepSeek `deepseek-flash`＋OpenRouter Jev `typesafe/jev-1.13` 真实物理抓放：1 次规划/11 次判定、47.220 s 仿真、0.5937274 m 搬运，成功后销毁测试会话；无自动重试/模型切换，未将 Jev 密钥复用于其他规划模型。Jev 报告费用 $0.000642894，DeepSeek 未报告费用，不能视为零。
+- 修正网站任务输入的能力误导：mock 指令不可编辑，明确目前只有固定单方块抓放；自定义中文任务阻止启动并可恢复标准指令，不再无视编辑继续旧任务。这是防误执行保护，不是自由语言任务功能；原本地模式不改。订阅设备码失败提示移至登录按钮旁，说明未取得验证链接及需要手动打开官方页面；服务器官方链路仍受限，不宣称恢复订阅。
+- 增加显式授权、无凭据落盘/trace 的公网单回合测试与前端防误执行/设备码展示回归；615 项单元测试、双构建、网站假上游 2/2 通过。提示修补发布为 `20260924T023534Z-web`，原 `v1.0.1` Git 标签不变；详见 `docs/website-acceptance-2026-09-24.md`。

 ## 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、不加载 `.env`，不共享用户密钥/账号/任务。通过反向代理 HTTPS 使用安全 Cookie/CSRF；生产容器仅发布回环端口。原本机模式保持不变。
+`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。

-网站配置原子保存 DeepSeek/OpenRouter LLM 和独立 OpenRouter Jev 密钥，固定受控上游。订阅使用每会话独立 Codex 0.147.0 的官方设备码流程，不开放 localhost 回调或任意 RPC；当前目标主机官方网络受限，明确报告不可用，不回退付费 API。见 [网站 API](../docs/website-api.md) 和 [部署手册](../docs/website-deployment.md)。
+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。

-## 启动
+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。

+- 如果链接已有查询参数，使用 `&robot=lekiwi-v1`。其他参数不影响加载。
+- 打开页面后自动下载、校验、解压，选择 `URDF/LeKiwi.urdf` 和 `lekiwi-v1` profile，转换 MJCF 并加载进当前浏览器仿真；不再弹出入口/URDF 配置确认框。
+- 默认暂停，可点击播放或在「控制台 → 机器人语言控制」输入指令。URL 本身不触发机器人运动、付费模型、Python/ONNX 或外控授权。
+- 无 `robot` 参数：保持空白工作台，不下载 ZIP。未知、空值、重复参数：明确报错，不加载默认机器人，也不访问参数中的任意 URL/文件路径。
+- 刷新页面会重新导入；删除工程或手动换模型不会被参数反复覆盖。参数只在页面启动时读取，改变浏览器地址后需导航/刷新。
+- 下载或校验失败时显示错误，可刷新重试，也可直接手动导入；不自动重试。下载等待上限 120 秒，离开页面取消下载。

+## LeKiwi 双摄像头
+
+自动导入同时创建前置与腕部两台独立相机，不再用通用的“首个 camera/head 名称 + 10 cm 偏移 + 局部 +X”规则。原先误挂到 `Camera-Mount-v8` 支架且侧向取景，是位置和方向错误的原因。
+
+左下角画面顶部的「摄像头视角」下拉框可切换「前置摄像头」和「腕部摄像头」，默认前置。一次渲染选中的一路，避免完整 CAD 多视口的额外开销。切换只改变查看器使用的相机 ID，不重新加载模型、不推进物理、不改变控制权；隐藏/显示保留所选相机，同名相机在场景重编译后保持选择，刷新页面默认前置。
+
+### 前置摄像头
+
+- 固连 Body：`Camera-Model-v3`，MJCF 名称 `__platform_camera__`。
+- 局部光心（米）：`[-0.012161199990, 0.024589244440, -0.012071624890]`。

+- 参数由原始 URDF 的视觉原点和 STL 镜头坐标推导：STL 光轴为 +Z，镜头最前端 z=21.5 mm，虚拟光心放在其前方 1 mm，避免模型遮挡自身画面。MuJoCo 使用 -Z 看向前方、+Y 图像向上，不能直接套用 Body +X。
+- 经 profile 的 CAD -90° 转向后，镜头朝机器人前方 +X，保留 CAD 安装的向上 10° 倾角，图像不侧转/倒置，随底盘运动。初始世界光心约 `[0.130956, 0, 0.062079]` m。
+
+### 腕部摄像头

+- 使用腕部相机自己的 URDF 视觉原点推导光心与光轴，同样位于 STL 镜头前方 1 mm，不能照搬前置的局部姿态。初始世界光心约 `[0.215392, 0.004250, 0.168290]` m，初始前向约 `[-0.173648, 0, -0.984808]`，朝夹爪作业区；随腕部/手臂运动实时更新。
+- 两相机都由 MuJoCo 的 `cam_xpos/cam_xmat` 驱动画面；真实 WASM 运动学回归验证腕部运动不改变前置相机、转动底盘时两者同步跟随。
+
+两路都是 CAD 对齐的仿真视点，不是实机内外参标定；保持 45° 垂直视场角/640×480 配置。不增加控制桥相机 API，也不改原 ZIP/网格、动力学或手动 profile 的“无相机”行为。

-当前计划 **10/10 已完成**。自动回归、物理故障与真实双 API 回合已通过；用户明确确认以 **DeepSeek `deepseek-flash` + OpenRouter `typesafe/jev-1.13` 的主工作台真实抓放**作为最终验收，不再要求本次订阅推理回合。仅仿真，不控制实机。
+## 当前版本：语言控制 v2（已部署，真实模型待验收）
+
+网站已发布 `20260924T065821Z-language-v2`，公网非付费验证 3/3 通过；没有将部署/加载成功视为真实模型推理成功。[发布及回滚记录](lekiwi-language-v2-release.md)。
+
+本地/网站统一为「控制台 → 机器人语言控制」，只保留预设、指令、执行/停止与简短状态。先点击**载入预设场景**，再输入：
+
+- `把方块搬到 B 区`（A `[0.257,0.45,0.128]`，B `[0.257,0.75,0.128]`）。
+- `把方块搬到 (0.25,0.50) 米`，或 `搬到 X=0.25 Y=0.50 Z=0.128`。
+- 仍支持 `前进0.5米`、`左转90度`、`停止`。停止无需模型。
+
+**坐标约定**：世界坐标、米、Z 向上；XY 根据真实支撑面补 Z，XYZ 的 Z 是方块中心而非台面。目标台允许输入的连续范围（不代表每个点都已做物理成功率评估）X `[0.237,0.277]`、Y `[0.365,0.865]`，Z `0.128`；另保留源台支撑区域。支持米/厘米/毫米，但不接受任意空间点、悬空目标、未知对象或相对坐标。单次持物搬运距离 `0.08–1 m`。底盘需处于预设净空走廊 X `[-0.06,0.04]` / Y `[-0.12,0.95]`、初始航向误差 ≤0.15 rad，超出时明确拒绝而非通用导航。
+
+只有“载入预设”会重建场景；执行不重置方块、不移动支撑台，支持从上次放置后的实测位置再次搬运。空工作台点击加载可校验并导入内置机器人；替换其他工程需确认。地图/RL 和双摄像头保留。旧面板的配置、mock、单技能/导出按钮已移除；诊断通过只读 `robot-task-result` 事件采集，不提供仿真写句柄。旧 v1 物理/API 夹具保留，不代表旧产品界面仍存在。
+
+### 分层实现
+
+- **LLM 任务层**：`/command` 解析受限意图与目标，`/plan` 给出带前置条件的合法技能链。两次请求共用 run/scene 身份与预算；后端配置模型，见 [本地启动](../decision_server/README.md)。没有服务时明确报错，不转 mock。
+- **Jev 监督层**：`TaskSupervisor` 消费一次多问题请求中的 Choice（合法切换）、Noul（allow/deny/uncertain）、Score（离散等级）。等级 poor/partial/good/excellent 映射 0/25/75/100，unavailable 不评分；它是**最近技能边界**的模型意见，不是概率或终局物理成功。为减少调用，本轮不增加可选终局评分请求。
+- **执行层**：`TaskPlanner` 根据实测状态计算停靠位并以 scratch IK 预检；`PickPlaceExecutor` 复用限速伺服/技能与物理证据，添加收臂/接近阶段。正常夹爪—台面接触仅在指定抓放阶段、底盘速度 ≤0.03 m/s、总力 ≤20 N 时允许；其他外部碰撞停止。这是仿真阈值，不是实机安全认证。
+- **底层**：原 MuJoCo 位置/速度伺服与唯一 `SimulationSession` 时钟，不引入 ROS2/MoveIt2，不瞬移物体、不焊接吸附。等待模型冻结物理，迟到响应、取消和硬安全不能被模型覆盖。
+
+### 本轮精简验收
+
+- 主工作台真实 WASM＋同源网关＋**假 HTTP 模型上游**连续两次成功：B 区有效搬运 **0.728882 m**、误差 **7.54 mm**；自由坐标有效搬运 **0.241201 m**、误差 **8.92 mm**。每任务 2 次 LLM / 14 次 Jev（含意图审核），Score=75 来自明确假上游，不是真实模型能力证明。证据：`build/e2e/lekiwi-language/`。
+- 20 个停靠位/高度 scratch IK 检查与真实夹爪锁开失败用例通过；锁开为 `empty_grasp`、搬运 0、成功 false。证据：`build/e2e/lekiwi-language-safety/`。
+- 原 v1 种子 0 基线通过，搬运 0.593793 m；网站构建移动/转向/停止两用例通过。证据：`build/e2e/lekiwi-language-v1-regression/`、`build/e2e/lekiwi-language-website-smoke/`。
+- 定向前端 13 文件 / 83 测试通过；Python 29 项中 28 通过、1 个既有可选项跳过；typecheck、定向 lint、双构建通过（保留大 chunk 提示）；未跑全仓/训练/多种子耐久。实现验收未读取真实密钥、未调用真实 LLM/Jev；随后已按用户要求部署，沿用服务器凭据，公网仅做非付费验证。真实模型需后续用服务器配置明确授权验收，不能引用下方历史结果当作 v2 通过。

+## 两个问题的原因与处理
+
+### 订阅点击后不打开网页
+
+当前设计是官方设备码登录：服务器先申请设备码与验证地址，再由用户点击官方链接；不是按钮直接自动弹窗。服务器实测 `auth.openai.com` 返回 403，ChatGPT 推理地址连接被拒绝；真实设备码请求仍返回 502 / `codex_rpc_failed`，没有生成可使用的设备码/链接。
+
+已将状态和错误移到登录按钮旁，明确申请步骤及没有验证链接的情况。未改用非官方中转，未借用全局账号，未自动切付费 API。服务器网络/官方资格问题未解决，订阅仍不可用。最终容器内活动 Codex 进程数为 0。
+
+### 编辑中文指令但动作不变
+
+`MockDecisionProvider.plan()` 不读取指令；真实规划契约也强制固定物体、固定技能顺序，动作目标由场景坐标决定。原界面允许任意编辑会造成“指令已生效”的错误预期。
+
+本次网站防误执行保护：
+
+- 明确标注“固定单方块抓放，非自由中文任务控制”。
+- mock 模式禁用无效的指令编辑。
+- 自定义指令在开始前被拦截，不加载旧任务、不调用模型，并提供恢复标准指令按钮。
+- 放置目标仍通过已有受限坐标修改，安全门禁不变；本地模式行为保留。
+
+**尚未实现把任意中文转换为新任务。** 待用户提供具体希望执行的指令后，才能确定所需技能、任务约束与验收；不能用取消安全顺序验证来假装支持。

 1. 保留工作树变更基线，运行 TS/Vitest/Python/Playwright 门禁。`build/website-deployment/baseline/` 保存部署前工作树摘要，不包含 `.env`。
 2. 使用 [官方 crane v0.20.6](https://github.com/google/go-containerregistry/releases/tag/v0.20.6)，校验 release checksums。将 `deploy/cadworld/images.lock.json` 中的 linux/amd64 digest 拉为 docker archive（`crane pull --platform linux/amd64 REF FILE`）；不需要本机 Docker daemon，也不让服务器访问不明镜像源。
 3. 为 Python 3.12 下载 `requirements.lock.txt` 指定 wheels，验证 hash；从官方 npm `@openai/codex@0.147.0-linux-x64` 包验证 registry 的 integrity 后提取二进制。文件放在 `build/website-deployment/vendor/{wheels/,codex,codex-origin.json}`。不复制任何用户的 Codex HOME/auth.json。

+
+- 只读取授权的 `Deepseek_API_KEY` 与 `OPENROUTER_API_KEY`。没有整份上传 `.env`，没有读取其他凭据或全局 Codex 登录。
+- 固定 `deepseek-flash` / Responses 与 `typesafe/jev-1.13` / OpenRouter Decisions，不改模型或使用其他 OpenRouter 主规划模型。
+- 密钥通过 SSH 标准输入传输，不进命令参数或日志。服务器文件 `/opt/cadworld-sim/secrets/model-keys.env` 为 0400 / 10001:10001，父目录 root/0700；仅文件只读挂入应用容器。
+- 网页/静态包/镜像/Git 均无密钥。上线前对静态构建扫描两项真实密钥；公网 `/.env` 和 `/run/secrets/model-keys.env` 返回 404。
+- 前端无模型、密钥、BYOK 或订阅设置；公开配置、模型目录、付费连接测试和订阅接口在共享模式返回 403。本地旧界面和官方订阅实现不删除。
+- 全站共享**60 次/小时、600 次/滚动24小时**的上游调用预留限额，生产并行 2；`/command` 预留 2 次，其他推理 1 次。失败不退款，SQLite 留在宿主预算目录；换会话/部署不会清零。

+路径：**控制台 → 机器人语言控制**，先导入并选择 LeKiwi v1 profile。
+
+- 前进/后退：0.01–1 米，沿当前机器人朝向。

+- 可输入“把方块搬到支撑台”请求固定台面抓放演示；该动作会重载演示场景。移动与转向不重载模型。
+- 停止按钮、文本“停止”、隐藏、卸载、换场景/控制权可取消。已运行其他控制器时在付费请求之前拒绝，需用户先停止它。
+
+DeepSeek 只返回受限结构化意图，Jev 检查是否匹配单个请求。浏览器保留单一物理时钟与写入票据，使用实际底盘位姿闭环，而非修改 qpos/瞬移；完成要求误差稳定 0.3 s，位置 <8 mm、角度 <0.015 rad，且实际速度已降低。速度/加速度、倾斜/高度、障碍接触、时钟异常、30 s 仿真/60 s 墙钟上限均可停止动作。
+

+## 实际验收（区分证据）
+
+### 免费门禁

+- 网站生产资源＋真实网关/假 HTTP 上游：前进、左转、沿新朝向前进、右转、后退、方向含糊拒绝、运动中停止、完整抓放均通过（3 个 E2E 用例）。
+- 公网非付费检查 2/2：Pyodide、无密钥输入、未配置机器人零推理、只读模型配置、订阅关闭、秘密路径 404、会话销毁。
