+# ChatGPT / Codex subscription
+
+LangBot's **OpenAI Codex** model provider uses **Sign in with ChatGPT** and the account's Codex entitlement. It is separate from the existing OpenAI API-key provider: subscribing to ChatGPT does not supply an OpenAI Platform API key, and API-key billing is unchanged.
+
+## Connect an account
+
+1. Open **Models**, choose **Add Provider**, and select **OpenAI Codex**.
+2. Enter a provider name and choose **Save and sign in**. This saves the provider before authorization, so an interrupted login can be retried from its settings.
+3. Open the OpenAI authorization link and enter the one-time code displayed in LangBot. Sign in on OpenAI's site, not in LangBot.
+4. If OpenAI asks you to enable device-code authorization, enable it in your ChatGPT account's security settings, or contact your workspace administrator.
+5. Keep the LangBot dialog open until it confirms the connection, then finish the form.
+6. Use the existing **Scan models** or **Add model** controls, test the model, and select it in a pipeline as usual. Only LLM models are supported by this provider.
+
+The device-code flow also works when LangBot runs remotely or in Docker: the browser does not need to reach a localhost OAuth callback on the server. Serve the LangBot management panel over HTTPS when accessing it remotely.
+
+The account's model catalog is authoritative. A model listed elsewhere or entered manually is not a guarantee that this account has access. Scan errors are reported rather than replaced with a fabricated available-model list.
+
+## Reconnect and disconnect
+
+Open the provider's existing settings to sign in again or disconnect. LangBot refreshes expiring access tokens automatically. A revoked or invalid refresh grant requires another sign-in; transient network failures are not proof that the grant was revoked.
+
+**Disconnect** removes this provider's locally stored authorization. It does not log the account out of other applications or revoke the account globally. Canceling a pending sign-in is separate from disconnecting an existing account. Removing a provider also removes its authorization; the normal rule that models must be removed first still applies.
+
+A saved provider can remain disconnected. Scanning or invoking it then returns a sign-in-required error; LangBot does not silently switch to paid API-key billing.
+
+## Usage and deployment boundary
+
+Calls consume the connected account's included Codex usage and remain subject to OpenAI's plan limits, model availability, workspace policies, and terms. Token counts recorded by LangBot are request usage, not a measurement of remaining subscription quota or an OpenAI invoice.
+
+Use this integration for your own authorized account and trusted workflows. Third-party sign-in support is not permission to pool accounts, resell subscription quota, or redistribute one subscription as a shared API service. For a public or commercial multi-user service, use the appropriate OpenAI API or separately authorized enterprise arrangement. The provider remains a Workspace resource in LangBot: consider who can invoke its models before connecting a personal account.
+
+## Credential handling and API surface
+
+- OAuth credentials are stored server-side separately from provider API keys. Provider and model reads do not supply OAuth access, refresh, or ID tokens.
+- Authorization uses a fixed OpenAI origin. The Codex provider does not accept a custom base URL or manually supplied API keys.
+- Authentication controls require an authenticated LangBot browser user with `provider_secret.manage` in the selected Workspace. Pending attempts are scoped to the Workspace, provider, and initiating user.
+- Browser storage must not contain OAuth tokens. Treat the server database and its backups as sensitive application data.
+- MCP and LangBot API keys do not expose the browser-only OAuth controls. Agents may inspect configured providers and models with the existing tools, but a human connects the subscription in the management panel.
+
+The provider-scoped authentication routes are under `/api/v1/provider/providers/{uuid}/codex`:
+
+| Method | Suffix | Purpose |
+| --- | --- | --- |
+| GET | `/status` | Read local connection state without returning credentials |
+| POST | `/device` | Start device authorization |
+| POST | `/device/poll` | Poll the initiating user's authorization attempt |
+| DELETE | `/device/{authorization_id}` | Cancel only that pending attempt |
+| DELETE | `/auth` | Remove local authorization |
+
+Use the returned polling interval and expiration time. An expired attempt must be restarted. These routes are not a general-purpose subscription-to-API gateway.

+## 中文快速说明
+
+在「模型」中添加提供商，选择 **OpenAI Codex**，填写名称并点击「保存并登录」。打开 OpenAI 授权页面，输入 LangBot 显示的一次性验证码，完成授权后回到原对话框。随后照常扫描或添加模型、测试模型，并在流水线中选择它。
+
+无需填写 API Key，也无需为远程服务器配置 localhost 回调。登录中断后可以从该提供商的设置中重试；断开连接只删除 LangBot 中保存的授权。调用消耗所登录账号的 Codex 额度，受账号实际权限和 OpenAI 限制约束，不会自动转用按量付费的 OpenAI API。
+
+此功能用于自己的授权账号及可信工作流，不应将个人订阅作为面向多个用户转售或共享的 API 服务。提供商仍是 LangBot 工作空间内的资源，连接个人账号前请确认模型的使用范围。

+to paste ChatGPT access tokens, refresh tokens, or a Codex auth cache into an
+MCP tool or model configuration.
+
+A human connects or disconnects the subscription through **Models → provider
+settings** in the LangBot web UI. The provider-scoped `/codex/*` authentication
+routes deliberately require a browser-user session and are not exposed as MCP
+tools or authorized by a LangBot API key. Once connected, models are managed
+and selected through the normal provider/model workflow. A disconnected
+provider must be reauthorized; do not silently replace it with API-key billing.
+
+See [ChatGPT / Codex subscription](../../../docs/CODEX_SUBSCRIPTION.md) for setup,
+usage limits, and the personal-account versus shared-service boundary.
+
+## Provider deletion
+
+The curated MCP surface currently lists providers but has no provider-deletion
+tool. In the web UI, **Edit Provider → Delete** asks for confirmation before
+removing that provider and all its LLM, embedding, and rerank models. This is
+irreversible; never interpret a request to edit a provider as authorization to
+delete it.
+
+The equivalent HTTP operation is
+`DELETE /api/v1/provider/providers/{uuid}?cascade=true`, requiring
+`resource.manage` in the authenticated Workspace. Omitting `cascade` preserves
+the existing refusal to delete providers that still have models. Cloud-managed
+providers remain protected. Cascade deletion removes stored Codex authorization
+state as well; it is not the same operation as disconnecting an account.

+"""ESPL V3 adapter — WebSocket server for E-SP-Line2's Adapter Gateway (接入器).
+
+LangBot acts as a server-mode WebSocket endpoint. E-SP-Line2's adapter (接入器)
+in **client mode** connects to this endpoint (or a reverse proxy forwards it)
+and exchanges e-commerce messages:
+
+* **Inbound**  — E-SP-Line2 broadcasts ``message.received`` envelopes to every
+  connected adapter client. This adapter converts each envelope into a LangBot
+  ``FriendMessage`` / ``GroupMessage`` event (the ``conversation_id`` maps to
+  the LangBot launcher/session id) and fires it into the normal pipeline.
+* **Outbound** — every ``reply_message`` / ``reply_message_chunk`` the pipeline
+  emits is converted into an ESPL v3 outbound ``message`` frame
+  (``command_type: send_text``) and sent back over the WebSocket that carries
+  the matching conversation.
+
+Design notes:
+
+* Listens on ``ws://<host>:<port>/ws`` (default ``ws://127.0.0.1:8000/ws``).
+  In E-SP-Line2 create a **client-mode** 接入器 with ``ws_url`` pointing here.
+* Supports multiple simultaneous E-SP-Line2 connections. Each connection is
+  identified by its ``adapter_id`` (from the ``key``/path) so outbound replies
+  route back to the correct connection.
+* Heartbeats: responds to ``ping`` frames with ``pong``; the E-SP-Line2
+  gateway also sends server pings that we answer automatically via the
+  websockets library.
+* The ``conversation_id`` from the inbound envelope is used as the LangBot
+  launcher id so each e-commerce conversation maps 1:1 to an isolated LangBot
+  session. Replies are routed back to the same ``conversation_id``.
+* ``instance_id`` is captured from the inbound envelope and stashed on the
+  event's ``source_platform_object``.
+
+See docs/user-guide/adapter-gateway.md in the E-SP-Line2 repo for the full
+ESPL v3 protocol reference.
