+# 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。
+
+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)。
+
+## 启动
+
+```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。前端需要 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
+
+| 路由                                              | 方法 | 内容                                                        |
+| ------------------------------------------------- | ---- | ----------------------------------------------------------- |
+| `/status`                                         | GET  | 版本、非秘密配置、调用摘要；没有 prompt、响应原文或账号地址 |
+| `/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}`                       |
+| `/decide`                                         | POST | `{observation,candidates,failure?}`                         |
+| `/cancel`                                         | POST | `{runId,requestId}`                                         |
+| `/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。

+    or a Contribution incorporated within the Work constitutes direct
+    or contributory patent infringement, then any patent licenses
+    granted to You under this License for that Work shall terminate
+    as of the date such litigation is filed.
+
+4.  Redistribution. You may reproduce and distribute copies of the
+    Work or Derivative Works thereof in any medium, with or without
+    modifications, and in Source or Object form, provided that You
+    meet the following conditions:
+
+    (a) You must give any other recipients of the Work or

+    (c) You must retain, in the Source form of any Derivative Works
+    that You distribute, all copyright, patent, trademark, and
+    attribution notices from the Source form of the Work,
+    excluding those notices that do not pertain to any part of
+    the Derivative Works; and
+
+    (d) If the Work includes a "NOTICE" text file as part of its
+    distribution, then any Derivative Works that You distribute must
+    include a readable copy of the attribution notices contained
+    within such NOTICE file, excluding those notices that do not
+    pertain to any part of the Derivative Works, in at least one
+    of the following places: within a NOTICE text file distributed
+    as part of the Derivative Works; within the Source form or
+    documentation, if provided along with the Derivative Works; or,
+    within a display generated by the Derivative Works, if and
+    wherever such third-party notices normally appear. The contents
+    of the NOTICE file are for informational purposes only and
+    do not modify the License. You may add Your own attribution
+    notices within Derivative Works that You distribute, alongside
+    or as an addendum to the NOTICE text from the Work, provided
+    that such additional attribution notices cannot be construed
+    as modifying the License.
+
+    You may add Your own copyright statement to Your modifications and
+    may provide additional or different license terms and conditions
+    for use, reproduction, or distribution of Your modifications, or
+    for any such Derivative Works as a whole, provided Your use,

+    any Contribution intentionally submitted for inclusion in the Work
+    by You to the Licensor shall be under the terms and conditions of
+    this License, without any additional terms or conditions.
+    Notwithstanding the above, nothing herein shall supersede or modify
+    the terms of any separate license agreement you may have executed
+    with Licensor regarding such Contributions.
+
+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
+    Contributor provides its Contributions) on an "AS IS" BASIS,
+    WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+    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.
+
+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
+    result of this License or out of the use or inability to use the
+    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
