+### 3.1 Complete Telegram Login / OIDC setup
+
+#### 1. Generate `data/telegram-login` once
+
+Run this from the `telesrv` repository root:
+
+```powershell
+go run ./cmd/telegramloginkeygen -mode init -dir data/telegram-login
+Get-ChildItem .\data\telegram-login
+```
+
+The same command works on Linux; restrict the generated directory afterward:
+
+```bash
+go run ./cmd/telegramloginkeygen -mode init -dir data/telegram-login
+chmod 0700 data/telegram-login
+chmod 0600 data/telegram-login/*
+```
+
+Initialization creates the following private files. It never prints key material and refuses to
+overwrite an existing `signing-keys.json`, `code-keys.json`, or `client-secret-pepper`:
+
+- `signing-keys.json` plus three `signing-*.pem` files: the manifest and private keys for RS256,
+  ES256, and EdDSA ID-token signatures;
+- `code-keys.json`: the AES-256-GCM envelope-key ring for one-time authorization codes;
+- `client-secret-pepper`: a 32-byte deployment pepper used to store and verify OIDC Client Secret
+  digests.
+
+The repository ignores `data/*` by default. Never put this directory in Git, release archives,
+logs, or ordinary backups. All instances must mount the same protected files and restart together
+after rotation. Losing the pepper invalidates existing Client Secret verification. Losing a signing
+key that is still in its publication window invalidates otherwise-live ID tokens against JWKS.
+
+#### 2. Configure and start the Provider
+
+This example exposes OIDC directly at `http://192.0.2.25:2401`; replace it with the server address
+that clients can actually reach. Bind `0.0.0.0:2401` for direct LAN/public access, or keep
+`127.0.0.1:2401` when an on-host reverse proxy is the only caller:
+
+```env
+TELESRV_PUBLIC_BASE_URL=http://192.0.2.25:2401
+TELESRV_PUBLIC_LINK_WEB_ADDR=0.0.0.0:2401
+TELESRV_PUBLIC_APP_SCHEME=telesrv
+
+TELESRV_TELEGRAM_LOGIN_ENABLE=true
+TELESRV_TELEGRAM_LOGIN_ISSUER=http://192.0.2.25:2401
+TELESRV_TELEGRAM_LOGIN_ALLOW_HTTP=true
+TELESRV_TELEGRAM_LOGIN_SIGNING_KEYS_FILE=data/telegram-login/signing-keys.json
+TELESRV_TELEGRAM_LOGIN_CODE_KEYS_FILE=data/telegram-login/code-keys.json
+TELESRV_TELEGRAM_LOGIN_SECRET_PEPPER_FILE=data/telegram-login/client-secret-pepper
+```
+
+For HTTPS, set the issuer and public base to the exact HTTPS origin and leave
+`TELESRV_TELEGRAM_LOGIN_ALLOW_HTTP=false`. The issuer becomes the token `iss` and the root of all
+discovery endpoints, so its scheme, host, and port must exactly match the address used by relying
+parties. Start or restart `telesrv`, then verify the public endpoints:
+
+```powershell
+curl.exe http://192.0.2.25:2401/.well-known/openid-configuration
+curl.exe http://192.0.2.25:2401/.well-known/jwks.json
+curl.exe -I http://192.0.2.25:2401/js/telegram-login.js
+```
+
+The discovery `issuer` must equal the configured value, and its `authorization_endpoint`,
+`token_endpoint`, and `jwks_uri` must be reachable by the relying party. A reverse proxy must pass
+through `/.well-known/openid-configuration`, `/.well-known/jwks.json`, `/auth`, `/auth/status`,
+`/token`, `/crossapp`, `/inapp`, `/telegram-login.js`, and `/js/telegram-login.js` unchanged.
+
+#### 3. Create an OIDC Client with the local `@BotFather`
+
+Create a bot with `/newbot` or select an existing bot. In the local `@BotFather`, run `/setlogin`
+and choose that bot. Initial setup returns:
+
+- `Client ID`: the bot user ID as a decimal string;
+- `Client Secret`: shown once, separate from the Bot API token, and meant to be saved immediately
+  in a secret manager.
+
+Send each configuration command separately. This example runs the relying party at
+`http://192.0.2.30:3000`:
+
+```text
+add origin http://192.0.2.30:3000
+add redirect http://192.0.2.30:3000/oauth/callback
+algorithm RS256
+enable
+```
+
+An `origin` is an exact Web origin without a path, query, or fragment; it authorizes the JS SDK,
+popup CORS, and legacy `login_url`. A `redirect` is the exact full URI that receives an
+Authorization Code. Wildcards and prefix matching are not supported. Use `/logininfo` to inspect
+status and registrations; use `/setlogin` to add/remove URLs, change the algorithm, or disable the
+client; use `/resetloginsecret` to rotate the Client Secret. Available algorithms are RS256,
+ES256, EdDSA, and ES256K only when its build/key ring is present. EdDSA and ES256K accept only the
+`openid` scope.
+
+#### 4. Integrate a relying party with standard OIDC
+
+Start by loading:
+
+```text
+http://192.0.2.25:2401/.well-known/openid-configuration
+```
+
+The standard flow is Authorization Code with PKCE S256:
+
+1. Generate random `state`, `nonce`, and PKCE `code_verifier`; derive the S256 `code_challenge`.
+2. Open the discovery `authorization_endpoint` with `client_id`, the exact `redirect_uri`,
+   `response_type=code`, a `scope` containing `openid`, `state`, `nonce`, `code_challenge`, and
+   `code_challenge_method=S256`.
+3. After the user approves in TDesktop/Android, verify `state` at the relying-party callback and
+   read the one-time code.
+4. Server-side, POST `grant_type=authorization_code`, the code, the same `redirect_uri`, and
+   `code_verifier` to the discovery `token_endpoint`. Confidential clients authenticate with HTTP
+   Basic or `client_secret_post`.
+5. Verify the ID-token signature with the discovery `jwks_uri`, then strictly validate `iss`,
+   `aud`, `exp`, `nonce`, and a non-empty `sub`. Decoding without signature verification is not
+   sufficient.
+
+Supported scopes are `openid`, `profile`, `phone`, and `telegram:bot_access`. The provider does not
+currently expose UserInfo, refresh tokens, or an introspection endpoint. Browser applications may
+load `<issuer>/js/telegram-login.js` for the local JS SDK. A Client Secret must remain server-side.
+
+#### 5. Verify the complete path with the Bedolaga demo
+
+Install the demo dependencies:
+
+```powershell
+python -m venv "$env:TEMP\telesrv-bedolaga-demo-venv"
+& "$env:TEMP\telesrv-bedolaga-demo-venv\Scripts\python.exe" -m pip install `
+  -r .\cmd\bots\bedolagaformat\requirements.txt
+```
+
+Put the Client ID/Secret from step 3 and the same bot's Bot API token only in process environment:
+
+```powershell
+$env:TELESRV_BOT_TOKEN = "<bot_id>:<bot_api_secret>"
+$env:TELESRV_BOT_API_SERVER = "http://192.0.2.25:8081"
+$env:TELESRV_BOT_LOGIN_DEMO = "1"
+$env:TELESRV_BOT_LOGIN_ISSUER = "http://192.0.2.25:2401"
+$env:TELESRV_BOT_LOGIN_CLIENT_ID = "<Client ID returned by BotFather>"
+$env:TELESRV_BOT_LOGIN_CLIENT_SECRET = "<one-time OIDC Client Secret>"
+$env:TELESRV_BOT_LOGIN_PUBLIC_URL = "http://192.0.2.30:3000"
+$env:TELESRV_BOT_LOGIN_LISTEN = "0.0.0.0:3000"
+
+& "$env:TEMP\telesrv-bedolaga-demo-venv\Scripts\python.exe" `
+  .\cmd\bots\bedolagaformat\demo.py --drop-pending --login-demo
+```
+
+The BotFather origin must equal `TELESRV_BOT_LOGIN_PUBLIC_URL`, and the redirect must equal
+`<TELESRV_BOT_LOGIN_PUBLIC_URL>/oauth/callback`. Send `/logindemo` to the bot. The first button
+tests Bot API `login_url` plus the HMAC callback; the second page tests the local JS SDK popup and
+Authorization Code + PKCE/JWKS. Omitting the Client Secret leaves JS popup verification available
+but explicitly disables the server-side code flow.
+
+#### 6. Rotate keys
+
+When rotating a signing key, retain the old public key for at least the configured ID-token TTL
+plus ten minutes. Restart all instances together after the operation:
+
+```powershell
+go run ./cmd/telegramloginkeygen -mode rotate-signing -algorithm RS256 `
+  -id-token-ttl 1h -publish-for 2h -dir data/telegram-login
+go run ./cmd/telegramloginkeygen -mode rotate-code -dir data/telegram-login
+```
+
+Run `rotate-signing` separately for RS256, ES256, or EdDSA. `rotate-code` retains old code keys and
+adds a new active key. Do not edit manifests or PEM files manually, and never generate divergent
+key rings independently on different instances.

+### 3.1 Telegram Login / OIDC 完整启用流程
+
+#### 1. 一次性生成 `data/telegram-login`
+
+在 `telesrv` 仓库根目录执行：
+
+```powershell
+go run ./cmd/telegramloginkeygen -mode init -dir data/telegram-login
+Get-ChildItem .\data\telegram-login
+```
+
+Linux 部署也可使用同一命令；生成后应限制目录权限：
+
+```bash
+go run ./cmd/telegramloginkeygen -mode init -dir data/telegram-login
+chmod 0700 data/telegram-login
+chmod 0600 data/telegram-login/*
+```
+
+初始化会生成以下私密文件，命令不会把密钥内容输出到终端，并会拒绝覆盖已经存在的
+`signing-keys.json`、`code-keys.json` 或 `client-secret-pepper`：
+
+- `signing-keys.json` 和三个 `signing-*.pem`：RS256、ES256、EdDSA ID token 签名私钥及清单；
+- `code-keys.json`：一次性 authorization code 使用的 AES-256-GCM envelope key ring；
+- `client-secret-pepper`：保存和校验 OIDC Client Secret 摘要时使用的 32 字节部署 pepper。
+
+`data/*` 默认已被仓库 `.gitignore` 排除。不要把该目录放入 Git、发布压缩包、日志或
+普通备份；多实例必须挂载同一份受保护的文件，并在轮换后一起重启。丢失 pepper 会让
+现有 Client Secret 无法验证，丢失仍在发布窗口内的签名私钥会让尚未过期的 ID token
+无法继续通过 JWKS 验证。
+
+#### 2. 配置并启动 Provider
+
+以下示例直接通过 `http://192.0.2.25:2401` 对外提供 OIDC；请替换成客户端实际可达的
+服务器 IP。直接监听局域网/公网网卡时使用 `0.0.0.0:2401`，仅由同机反向代理转发时
+应改回 `127.0.0.1:2401`：
+
+```env
+TELESRV_PUBLIC_BASE_URL=http://192.0.2.25:2401
+TELESRV_PUBLIC_LINK_WEB_ADDR=0.0.0.0:2401
+TELESRV_PUBLIC_APP_SCHEME=telesrv
+
+TELESRV_TELEGRAM_LOGIN_ENABLE=true
+TELESRV_TELEGRAM_LOGIN_ISSUER=http://192.0.2.25:2401
+TELESRV_TELEGRAM_LOGIN_ALLOW_HTTP=true
+TELESRV_TELEGRAM_LOGIN_SIGNING_KEYS_FILE=data/telegram-login/signing-keys.json
+TELESRV_TELEGRAM_LOGIN_CODE_KEYS_FILE=data/telegram-login/code-keys.json
+TELESRV_TELEGRAM_LOGIN_SECRET_PEPPER_FILE=data/telegram-login/client-secret-pepper
+```
+
+使用 HTTPS 时，把 `TELESRV_TELEGRAM_LOGIN_ISSUER` 和公开根地址改成精确 HTTPS
+origin，并保持 `TELESRV_TELEGRAM_LOGIN_ALLOW_HTTP=false`。issuer 是 token 的 `iss`
+以及 discovery 中所有端点的根地址，scheme、host 和 port 必须与依赖方访问的地址完全
+一致。启动或重启 `telesrv` 后，先验证公开端点：
+
+```powershell
+curl.exe http://192.0.2.25:2401/.well-known/openid-configuration
+curl.exe http://192.0.2.25:2401/.well-known/jwks.json
+curl.exe -I http://192.0.2.25:2401/js/telegram-login.js
+```
+
+discovery 返回的 `issuer` 必须等于配置值，`authorization_endpoint`、`token_endpoint`
+和 `jwks_uri` 必须可从依赖方访问。使用反向代理时需原样转发
+`/.well-known/openid-configuration`、`/.well-known/jwks.json`、`/auth`、`/auth/status`、
+`/token`、`/crossapp`、`/inapp`、`/telegram-login.js` 和 `/js/telegram-login.js`。
+
+#### 3. 用本服 `@BotFather` 创建 OIDC Client
+
+先用 `/newbot` 创建或选择已有 bot，然后在本服 `@BotFather` 中执行 `/setlogin` 并选择
+该 bot。首次配置会返回：
+
+- `Client ID`：bot user ID 的十进制字符串；
+- `Client Secret`：只显示一次，与 Bot API token 不同，必须立即保存到密钥管理系统。
+
+接着逐条发送配置命令。下面假设依赖方页面运行在 `http://192.0.2.30:3000`：
+
+```text
+add origin http://192.0.2.30:3000
+add redirect http://192.0.2.30:3000/oauth/callback
+algorithm RS256
+enable
+```
+
+`origin` 只能是无 path/query/fragment 的精确 Web origin，用于 JS SDK、popup CORS 和
+legacy `login_url`；`redirect` 是 Authorization Code Flow 返回 code 的精确完整 URI。
+不支持 wildcard 或 prefix 匹配。用 `/logininfo` 检查状态和登记值；用 `/setlogin`
+增删 URL、切换签名算法或 disable；用 `/resetloginsecret` 轮换 Client Secret。可用的
+签名算法为 RS256、ES256、EdDSA，以及仅在对应构建和 key ring 已提供时可选的 ES256K；
+EdDSA/ES256K 只允许 `openid` scope。
+
+#### 4. 依赖方接入标准 OIDC
+
+依赖方应首先读取：
+
+```text
+http://192.0.2.25:2401/.well-known/openid-configuration
+```
+
+标准流程为 Authorization Code + PKCE S256：
+
+1. 生成随机 `state`、`nonce` 和 PKCE `code_verifier`，计算 S256 `code_challenge`；
+2. 浏览器打开 discovery 中的 `authorization_endpoint`，携带 `client_id`、精确
+   `redirect_uri`、`response_type=code`、包含 `openid` 的 `scope`、`state`、`nonce`、
+   `code_challenge` 和 `code_challenge_method=S256`；
+3. 用户在 TDesktop/Android 中确认后，依赖方 callback 校验 `state` 并取得一次性 code；
+4. 服务端向 discovery 中的 `token_endpoint` POST `grant_type=authorization_code`、code、
+   同一 `redirect_uri` 和 `code_verifier`，机密 client 使用 HTTP Basic 或
+   `client_secret_post` 提交 Client Secret；
+5. 用 discovery 的 `jwks_uri` 验证 ID token 签名，并严格校验 `iss`、`aud`、`exp`、
+   `nonce` 和非空 `sub`。不要只解码而不验签。
+
+支持的 scope 为 `openid`、`profile`、`phone`、`telegram:bot_access`。当前不提供
+UserInfo、refresh token 或 introspection endpoint。浏览器前端可以加载
+`<issuer>/js/telegram-login.js` 使用本地 JS SDK；Client Secret 只能留在服务端。
+
+#### 5. 使用 Bedolaga demo 验证完整链路
+
+安装 demo 依赖：
+
+```powershell
+python -m venv "$env:TEMP\telesrv-bedolaga-demo-venv"
+& "$env:TEMP\telesrv-bedolaga-demo-venv\Scripts\python.exe" -m pip install `
+  -r .\cmd\bots\bedolagaformat\requirements.txt
+```
+
+将第 3 步得到的 Client ID/Secret 和同一个 Bot API token 仅放入进程环境：
+
+```powershell
+$env:TELESRV_BOT_TOKEN = "<bot_id>:<bot_api_secret>"
+$env:TELESRV_BOT_API_SERVER = "http://192.0.2.25:8081"
+$env:TELESRV_BOT_LOGIN_DEMO = "1"
+$env:TELESRV_BOT_LOGIN_ISSUER = "http://192.0.2.25:2401"
+$env:TELESRV_BOT_LOGIN_CLIENT_ID = "<BotFather 返回的 Client ID>"
+$env:TELESRV_BOT_LOGIN_CLIENT_SECRET = "<只显示一次的 OIDC Client Secret>"
+$env:TELESRV_BOT_LOGIN_PUBLIC_URL = "http://192.0.2.30:3000"
+$env:TELESRV_BOT_LOGIN_LISTEN = "0.0.0.0:3000"
+
+& "$env:TEMP\telesrv-bedolaga-demo-venv\Scripts\python.exe" `
+  .\cmd\bots\bedolagaformat\demo.py --drop-pending --login-demo
+```
+
+确保 BotFather 登记的 origin 等于 `TELESRV_BOT_LOGIN_PUBLIC_URL`，redirect 等于
+`<TELESRV_BOT_LOGIN_PUBLIC_URL>/oauth/callback`。在客户端向 bot 发送 `/logindemo`：第一颗
+按钮验证 Bot API `login_url` 和 HMAC 回调，第二颗按钮页面分别验证本地 JS SDK popup
+以及 Authorization Code + PKCE/JWKS。省略 Client Secret 时只能验证 JS popup，服务端
+code flow 会明确禁用。
+
+#### 6. 密钥轮换
+
+签名 key 轮换时，旧公钥发布窗口必须至少覆盖配置的 ID token TTL 再加 10 分钟；操作
+完成后所有实例一起重启：
+
+```powershell
+go run ./cmd/telegramloginkeygen -mode rotate-signing -algorithm RS256 `
+  -id-token-ttl 1h -publish-for 2h -dir data/telegram-login
+go run ./cmd/telegramloginkeygen -mode rotate-code -dir data/telegram-login
+```
+
+`rotate-signing` 可分别用于 RS256、ES256、EdDSA；`rotate-code` 保留旧 code key 并新增
+active key。不要手工编辑 manifest 或 PEM，不要在各实例上分别生成不一致的 key ring。
