+#### ⚠️ Important: Creating the Admin Account
+
+The initial admin account is **only created via the setup wizard** (served at `http://<host>:8080` on first run). The `default.admin_email` / `default.admin_password` fields in `config.yaml` are **not used** to create it — they exist in the template for historical reasons.
+
+Because step 5 above pre-creates `config.yaml`, the setup wizard will be **skipped on first run**: the server detects an existing config and boots straight into normal mode with an empty `users` table, so the first login attempt fails with `invalid email or password`.
+
+**Two ways to create the admin account:**
+
+1. **Recommended — let the wizard generate `config.yaml`:** Skip step 5 (do not run the `cp`). Start `./sub2api` directly; the setup wizard at `http://localhost:8080` walks you through database, Redis, and admin account setup, then writes `config.yaml` for you.
+
+2. **If you already created `config.yaml`:** Temporarily move it aside so the wizard can trigger on first run, then restore it afterwards:
+   ```bash
+   mv config.yaml config.yaml.bak
+   ./sub2api        # wizard runs at http://localhost:8080 and writes a fresh config.yaml

+## Grok / xAI OAuth Support
+
+Sub2API supports Grok subscription accounts through xAI OAuth and forwards OpenAI-compatible Responses traffic to xAI.
+
+### Supported Scope
+
+- Platform name: `grok`
+- Account type: OAuth subscription accounts
+- Public Responses targets: `/v1/responses`, `/responses`, and `/backend-api/codex/responses`, forwarded to `${XAI_BASE_URL:-https://api.x.ai/v1}/responses`
+- Public Claude-compatible target: `/v1/messages`, converted to xAI Responses and returned as Anthropic Messages output for Claude CLI style clients
+- Public Chat Completions targets: `/v1/chat/completions` and `/chat/completions`, forwarded to `${XAI_BASE_URL:-https://api.x.ai/v1}/chat/completions`
+- Codex CLI style Responses WebSocket ingress is accepted on the Responses targets and bridged to xAI HTTP/SSE Responses upstream
+- Initial text models: `grok-4.3`, `grok-build-0.1`, `grok-4.20-0309-reasoning`, `grok-4.20-0309-non-reasoning`, and `grok-4.20-multi-agent-0309`
+- Media targets for Grok groups: `/v1/images/generations`, `/images/generations`, `/v1/images/edits`, `/images/edits`, `/v1/videos/generations`, `/videos/generations`, `/v1/videos/{request_id}`, and `/videos/{request_id}`. Generation requests require the group image-generation permission.
+- Media models: `grok-imagine`, `grok-imagine-image-quality`, `grok-imagine-image`, `grok-imagine-edit`, `grok-imagine-video`, and `grok-imagine-video-1.5`
+- Out of scope for this provider: TTS, transcription, browser automation, cookies, and Grok web scraping
+
+### OAuth Configuration
+
+The Grok OAuth flow uses PKCE and does not require committing private secrets. The default client details follow the public xAI OAuth flow used by compatible clients, and every value can be overridden by environment variable:
+
+| Variable | Default |
+|----------|---------|
+| `XAI_OAUTH_CLIENT_ID` | Public xAI OAuth client ID |
+| `XAI_OAUTH_SCOPE` | `openid profile email offline_access grok-cli:access api:access` |
+| `XAI_OAUTH_REDIRECT_URI` | `http://127.0.0.1:56121/callback` |
+| `XAI_OAUTH_AUTHORIZE_URL` | `https://auth.x.ai/oauth2/authorize` |
+| `XAI_OAUTH_TOKEN_URL` | `https://auth.x.ai/oauth2/token` |
+| `XAI_BASE_URL` | `https://api.x.ai/v1` |
+
+Administrators can create or reauthorize Grok accounts from the dashboard, or use the admin API:
+
+| Endpoint | Purpose |
+|----------|---------|
+| `POST /api/v1/admin/grok/oauth/auth-url` | Generate an xAI OAuth authorization URL |
+| `POST /api/v1/admin/grok/oauth/exchange-code` | Exchange a callback URL, query string, or code for OAuth credentials |
+| `POST /api/v1/admin/grok/oauth/refresh-token` | Validate or refresh a Grok refresh token |
+| `POST /api/v1/admin/grok/accounts/:id/refresh` | Refresh an existing Grok account |
+
+Credential storage reuses the existing account JSON fields: `access_token`, `refresh_token`, `token_type`, `expires_at`, optional `email`, optional `subscription_tier`, and `entitlement_status`.
+
+### Usage And Quota Display
+
+xAI quota is passive. Sub2API does not invent subscription quota values; it records whitelisted xAI rate-limit headers from successful or rate-limited upstream responses when xAI sends them. Before the first usable upstream response, the dashboard shows quota as unknown and still displays local Sub2API usage stats.
+
+`401` responses mark the account as needing reauthorization. `403` responses are treated as entitlement or subscription-tier failures instead of token-refresh loops. `429` responses use `Retry-After` or a short cooldown to temporarily remove the account from scheduling.
+

+
+## 项目概述
+
+Sub2API 是一个 AI API 网关平台，用于分发和管理 AI 产品订阅的 API 配额。用户通过平台生成的 API Key 调用上游 AI 服务，平台负责鉴权、计费、负载均衡和请求转发。
+
+## 核心功能
+
+- **多账号管理** - 支持多种上游账号类型（OAuth、API Key）
+- **API Key 分发** - 为用户生成和管理 API Key
+- **精确计费** - Token 级别的用量追踪和成本计算
+- **智能调度** - 智能账号选择，支持粘性会话
+- **并发控制** - 用户级和账号级并发限制
+- **速率限制** - 可配置的请求和 Token 速率限制
+- **内置支付系统** - 支持 EasyPay 易支付、支付宝官方、微信官方、Stripe，用户自助充值，无需独立部署支付服务（[配置指南](docs/PAYMENT_CN.md)）
+- **管理后台** - Web 界面进行监控和管理
+- **外部系统集成** - 支持通过 iframe 嵌入外部系统（如工单等），扩展管理后台功能
+
+## 生态项目
+
+围绕 Sub2API 的社区扩展与集成项目：
+
+| 项目 | 说明 | 功能 |
+|------|------|------|
+| ~~[Sub2ApiPay](https://github.com/touwaeriol/sub2apipay)~~ | ~~自助支付系统~~ | **已内置** — 支付功能已集成到 Sub2API 中，无需独立部署。详见 [支付配置指南](docs/PAYMENT_CN.md) |
+| [sub2api-mobile](https://github.com/ckken/sub2api-mobile) | 移动端管理控制台 | 跨平台应用（iOS/Android/Web），支持用户管理、账号管理、监控看板、多后端切换；基于 Expo + React Native 构建 |
+
+## 技术栈
+
+| 组件 | 技术 |
+|------|------|
+| 后端 | Go 1.25.7, Gin, Ent |
+| 前端 | Vue 3.4+, Vite 5+, TailwindCSS |
+| 数据库 | PostgreSQL 15+ |
+| 缓存/队列 | Redis 7+ |
+
+---
+
+## Nginx 反向代理注意事项
+
+通过 Nginx 反向代理 Sub2API（或 CRS 服务）并搭配 Codex CLI 使用时，需要在 Nginx 配置的 `http` 块中添加：
+
+```nginx
+underscores_in_headers on;
+```
+
+Nginx 默认会丢弃名称中含下划线的请求头（如 `session_id`），这会导致多账号环境下的粘性会话功能失效。
+
+---
+
+## 部署方式
+
+### 方式一：脚本安装（推荐）
+
+一键安装脚本，自动从 GitHub Releases 下载预编译的二进制文件。
+
+#### 前置条件
+
+- Linux 服务器（amd64 或 arm64）
+- PostgreSQL 15+（已安装并运行）
+- Redis 7+（已安装并运行）
+- Root 权限
+
+#### 安装步骤
+
+```bash
+curl -sSL https://raw.githubusercontent.com/Wei-Shaw/sub2api/main/deploy/install.sh | sudo bash
+```
+
+脚本会自动：
+1. 检测系统架构
+2. 下载最新版本
+3. 安装二进制文件到 `/opt/sub2api`
+4. 创建 systemd 服务
+5. 配置系统用户和权限
+
+#### 安装后配置
+
+```bash
+# 1. 启动服务
+sudo systemctl start sub2api
+
+# 2. 设置开机自启
+sudo systemctl enable sub2api
+
+# 3. 在浏览器中打开设置向导
+# http://你的服务器IP:8080
+```
+
+设置向导将引导你完成：
+- 数据库配置
+- Redis 配置
+- 管理员账号创建
+
+#### 升级
+
+可以直接在 **管理后台** 左上角点击 **检测更新** 按钮进行在线升级。
+
+网页升级功能支持：
+- 自动检测新版本
+- 一键下载并应用更新
+- 支持回滚
+
+#### 常用命令
+
+```bash
+# 查看状态
+sudo systemctl status sub2api
+
+# 查看日志
+sudo journalctl -u sub2api -f
+
+# 重启服务
+sudo systemctl restart sub2api
+
+# 卸载
+curl -sSL https://raw.githubusercontent.com/Wei-Shaw/sub2api/main/deploy/install.sh | sudo bash -s -- uninstall -y
+```
+
+---
+
+### 方式二：Docker Compose（推荐）
+
+使用 Docker Compose 部署，包含 PostgreSQL 和 Redis 容器。
+
+#### 前置条件
+
+- Docker 20.10+
+- Docker Compose v2+
+
+#### 快速开始（一键部署）
+
+使用自动化部署脚本快速搭建：
+
+```bash
+# 创建部署目录
+mkdir -p sub2api-deploy && cd sub2api-deploy
+
+# 下载并运行部署准备脚本
+curl -sSL https://raw.githubusercontent.com/Wei-Shaw/sub2api/main/deploy/docker-deploy.sh | bash
+
+# 启动服务
+docker compose up -d
+
+# 查看日志
+docker compose logs -f sub2api
+```
+
+**脚本功能：**
+- 下载 `docker-compose.local.yml`（本地保存为 `docker-compose.yml`）和 `.env.example`
+- 自动生成安全凭证（JWT_SECRET、TOTP_ENCRYPTION_KEY、POSTGRES_PASSWORD）
+- 创建 `.env` 文件并填充自动生成的密钥
+- 创建数据目录（使用本地目录，便于备份和迁移）
+- 显示生成的凭证供你记录
+
+#### 手动部署
+
+如果你希望手动配置：
+
+```bash
+# 1. 克隆仓库
+git clone https://github.com/Wei-Shaw/sub2api.git
+cd sub2api/deploy
+
+# 2. 复制环境配置文件
+cp .env.example .env
+
+# 3. 编辑配置（生成安全密码）
+nano .env
+```
+
+**`.env` 必须配置项：**
+
+```bash
+# PostgreSQL 密码（必需）
+POSTGRES_PASSWORD=your_secure_password_here
+
+# JWT 密钥（推荐 - 重启后保持用户登录状态）
+JWT_SECRET=your_jwt_secret_here
+
+# TOTP 加密密钥（推荐 - 重启后保留双因素认证）
+TOTP_ENCRYPTION_KEY=your_totp_key_here
+
+# 可选：管理员账号
+ADMIN_EMAIL=admin@example.com
+ADMIN_PASSWORD=your_admin_password
+
+# 可选：自定义端口
+SERVER_PORT=8080
+```
+
+**生成安全密钥：**
+```bash
+# 生成 JWT_SECRET
+openssl rand -hex 32
+
+# 生成 TOTP_ENCRYPTION_KEY
+openssl rand -hex 32
+
+# 生成 POSTGRES_PASSWORD
+openssl rand -hex 32
+```
+
+```bash
+# 4. 创建数据目录（本地版）
+mkdir -p data postgres_data redis_data
+
+# 5. 启动所有服务
+# 选项 A：本地目录版（推荐 - 易于迁移）
+docker compose -f docker-compose.local.yml up -d
+
+# 选项 B：命名卷版（简单设置）
+docker compose up -d
+
+# 6. 查看状态
+docker compose -f docker-compose.local.yml ps
+
+# 7. 查看日志
+docker compose -f docker-compose.local.yml logs -f sub2api
+```
+
+#### 部署版本对比
+
+| 版本 | 数据存储 | 迁移便利性 | 适用场景 |
+|------|---------|-----------|---------|
+| **docker-compose.local.yml** | 本地目录 | ✅ 简单（打包整个目录） | 生产环境、频繁备份 |
+| **docker-compose.yml** | 命名卷 | ⚠️ 需要 docker 命令 | 简单设置 |
+
+**推荐：** 使用 `docker-compose.local.yml`（脚本部署）以便更轻松地管理数据。
+
+#### 启用“数据管理”功能（datamanagementd）
+
+如需启用管理后台“数据管理”，需要额外部署宿主机数据管理进程 `datamanagementd`。
+
+关键点：
+
+- 主进程固定探测：`/tmp/sub2api-datamanagement.sock`
+- 只有该 Socket 可连通时，数据管理功能才会开启
+- Docker 场景需将宿主机 Socket 挂载到容器同路径
+
+详细部署步骤见：`deploy/DATAMANAGEMENTD_CN.md`
+
+#### 访问
+
+在浏览器中打开 `http://你的服务器IP:8080`
+
+如果管理员密码是自动生成的，在日志中查找：
+```bash
+docker compose -f docker-compose.local.yml logs sub2api | grep "admin password"
+```
+
+#### 升级
+
+```bash
+# 拉取最新镜像并重建容器
+docker compose -f docker-compose.local.yml pull
+docker compose -f docker-compose.local.yml up -d
+```
+
+#### 轻松迁移（本地目录版）
+
+使用 `docker-compose.local.yml` 时，可以轻松迁移到新服务器：
+
+```bash
+# 源服务器
+docker compose -f docker-compose.local.yml down
+cd ..
+tar czf sub2api-complete.tar.gz sub2api-deploy/
+
+# 传输到新服务器
+scp sub2api-complete.tar.gz user@new-server:/path/
+
+# 新服务器
+tar xzf sub2api-complete.tar.gz
+cd sub2api-deploy/
+docker compose -f docker-compose.local.yml up -d
+```
+
+#### 常用命令
+
+```bash
+# 停止所有服务
+docker compose -f docker-compose.local.yml down
+
+# 重启
+docker compose -f docker-compose.local.yml restart
+
+# 查看所有日志
+docker compose -f docker-compose.local.yml logs -f
+
+# 删除所有数据（谨慎！）
+docker compose -f docker-compose.local.yml down
+rm -rf data/ postgres_data/ redis_data/
+```
+
+---
+
+### 方式三：源码编译
+
+从源码编译安装，适合开发或定制需求。
+
+#### 前置条件
+
+- Go 1.21+
+- Node.js 18+
+- PostgreSQL 15+
+- Redis 7+
+
+#### 编译步骤
+
+```bash
+# 1. 克隆仓库
+git clone https://github.com/Wei-Shaw/sub2api.git
+cd sub2api
+
+# 2. 安装 pnpm（如果还没有安装）
+npm install -g pnpm
+
+# 3. 编译前端
+cd frontend
+pnpm install
+pnpm run build
+# 构建产物输出到 ../backend/internal/web/dist/
+
+# 4. 编译后端（嵌入前端）
+cd ../backend
+VERSION="$(./scripts/resolve-version.sh)"
+go build -tags embed -ldflags="-X main.Version=${VERSION}" -o sub2api ./cmd/server
+
+# 5. 创建配置文件
+cp ../deploy/config.example.yaml ./config.yaml
+
+# 6. 编辑配置
+nano config.yaml
+```
+
+> **注意：** `-tags embed` 参数会将前端嵌入到二进制文件中。不使用此参数编译的程序将不包含前端界面。
+
+**`config.yaml` 关键配置：**
+
+```yaml
+server:
+  host: "0.0.0.0"
+  port: 8080
+  mode: "release"
+
+database:
+  host: "localhost"
+  port: 5432
+  user: "postgres"
+  password: "your_password"
+  dbname: "sub2api"
+
+redis:
+  host: "localhost"
+  port: 6379
+  password: ""
+
+jwt:
+  secret: "change-this-to-a-secure-random-string"
+  expire_hour: 24
+
+default:
+  user_concurrency: 5
+  user_balance: 0
+  api_key_prefix: "sk-"
+  rate_multiplier: 1.0
+```
+
+### Sora 功能状态（暂不可用）
+
+> ⚠️ 当前 Sora 相关功能因上游接入与媒体链路存在技术问题，暂时不可用。
+> 现阶段请勿在生产环境依赖 Sora 能力。
+> 文档中的 `gateway.sora_*` 配置仅作预留，待技术问题修复后再恢复可用。
+
+### Sora 媒体签名 URL（功能恢复后可选）
+
+当配置 `gateway.sora_media_signing_key` 且 `gateway.sora_media_signed_url_ttl_seconds > 0` 时，网关会将 Sora 输出的媒体地址改写为临时签名 URL（`/sora/media-signed/...`）。这样无需 API Key 即可在浏览器中直接访问，且具备过期控制与防篡改能力（签名包含 path + query）。
+
+```yaml
+gateway:
+  # /sora/media 是否强制要求 API Key（默认 false）
+  sora_media_require_api_key: false
+  # 媒体临时签名密钥（为空则禁用签名）
+  sora_media_signing_key: "your-signing-key"
+  # 临时签名 URL 有效期（秒）
+  sora_media_signed_url_ttl_seconds: 900
+```
+
+> 若未配置签名密钥，`/sora/media-signed` 将返回 503。  
+> 如需更严格的访问控制，可将 `sora_media_require_api_key` 设为 true，仅允许携带 API Key 的 `/sora/media` 访问。
+
+访问策略说明：
+- `/sora/media`：内部调用或客户端携带 API Key 才能下载
+- `/sora/media-signed`：外部可访问，但有签名 + 过期控制
+
+`config.yaml` 还支持以下安全相关配置：
+
+- `cors.allowed_origins` 配置 CORS 白名单
+- `security.url_allowlist` 配置上游/价格数据/CRS 主机白名单
+- `security.url_allowlist.enabled` 可关闭 URL 校验（慎用）
+- `security.url_allowlist.allow_insecure_http` 关闭校验时允许 HTTP URL
+- `security.url_allowlist.allow_private_hosts` 允许私有/本地 IP 地址
+- `security.response_headers.enabled` 可启用可配置响应头过滤（关闭时使用默认白名单）
+- `security.csp` 配置 Content-Security-Policy
+- `billing.circuit_breaker` 计费异常时 fail-closed
+- `server.trusted_proxies` 启用可信代理解析 X-Forwarded-For
+- `turnstile.required` 在 release 模式强制启用 Turnstile
+
+**网关防御纵深建议（重点）**
+
+- `gateway.upstream_response_read_max_bytes`：限制非流式上游响应读取大小（默认 `8MB`），用于防止异常响应导致内存放大。
+- `gateway.proxy_probe_response_read_max_bytes`：限制代理探测响应读取大小（默认 `1MB`）。
+- `gateway.gemini_debug_response_headers`：默认 `false`，仅在排障时短时开启，避免高频请求日志开销。
+- `/auth/register`、`/auth/login`、`/auth/login/2fa`、`/auth/send-verify-code` 已提供服务端兜底限流（Redis 故障时 fail-close）。
+- 推荐将 WAF/CDN 作为第一层防护，服务端限流与响应读取上限作为第二层兜底；两层同时保留，避免旁路流量与误配置风险。
+
+**⚠️ 安全警告：HTTP URL 配置**
+
+当 `security.url_allowlist.enabled=false` 时，系统仅执行最小 URL 校验，且**默认允许 HTTP URL**（开发友好模式，Docker Compose 部署的默认值一致）。生产环境建议显式收紧为仅允许 HTTPS：
+
+```yaml
+security:
+  url_allowlist:
+    enabled: false                # 禁用白名单检查
+    allow_insecure_http: false    # 仅允许 HTTPS（生产环境推荐）
+```
+
+**或通过环境变量：**
+
+```bash
+SECURITY_URL_ALLOWLIST_ENABLED=false
+SECURITY_URL_ALLOWLIST_ALLOW_INSECURE_HTTP=false
+```
+
+**允许 HTTP 的风险：**
+- API 密钥和数据以**明文传输**（可被截获）
+- 易受**中间人攻击 (MITM)**
+- **不适合生产环境**
+
+**适用场景：**
+- ✅ 开发/测试环境的本地服务器（http://localhost）
+- ✅ 内网可信端点
+- ✅ 获取 HTTPS 前测试账号连通性
+- ❌ 生产环境（仅使用 HTTPS）
+
+**设置 `allow_insecure_http: false` 后，HTTP URL 会返回如下错误：**
+```
+Invalid base URL: invalid url scheme: http
+```
+
+如关闭 URL 校验或响应头过滤，请加强网络层防护：
+- 出站访问白名单限制上游域名/IP
+- 阻断私网/回环/链路本地地址
+- 强制仅允许 TLS 出站
+- 在反向代理层移除敏感响应头
+
+#### ⚠️ 重要：创建管理员账号
+
+初始管理员账号**只能通过 setup 向导创建**（首次启动时访问 `http://<host>:8080`）。`config.yaml` 中的 `default.admin_email` / `default.admin_password` 字段**不会被用来创建管理员**——它们只是出于历史原因保留在模板里。
+
+由于上面第 5 步预先创建了 `config.yaml`，**setup 向导在首次启动时会被跳过**：服务检测到 config 已存在，会直接进入正常模式，此时 `users` 表为空，首次登录会返回 `invalid email or password`。
+
+**创建管理员的两种方式：**
+
+1. **推荐——让向导自动生成 `config.yaml`：** 跳过上面的第 5 步（不要执行 `cp`）。直接运行 `./sub2api`，访问 `http://localhost:8080`，向导会引导你完成数据库、Redis 和管理员账号配置，并自动写出 `config.yaml`。
+
+2. **如果你已经创建了 `config.yaml`：** 首次启动前先把它临时移走以触发向导，完成后再恢复：
+   ```bash
+   mv config.yaml config.yaml.bak
+   ./sub2api        # 向导在 http://localhost:8080 启动，并生成新的 config.yaml
+   # 向导完成后 Ctrl+C 停服，再恢复你的配置：
+   mv config.yaml.bak config.yaml
+   ./sub2api        # 重启进入正常模式，用刚创建的管理员登录
+   ```
+
+```bash
+# 6. 运行应用
+./sub2api
+```
+
+#### HTTP/2 (h2c) 与 HTTP/1.1 回退
+
+后端明文端口默认支持 h2c，并保留 HTTP/1.1 回退用于 WebSocket 与旧客户端。浏览器通常不支持 h2c，性能收益主要在反向代理或内网链路。
+
+**反向代理示例（Caddy）：**
+
+```caddyfile
+transport http {
+	versions h2c h1
+}
+```
+
+**验证：**
+
+```bash
+# h2c prior knowledge
+curl --http2-prior-knowledge -I http://localhost:8080/health
+# HTTP/1.1 回退
+curl --http1.1 -I http://localhost:8080/health
+# WebSocket 回退验证（需管理员 token）
+websocat -H="Sec-WebSocket-Protocol: sub2api-admin, jwt.<ADMIN_TOKEN>" ws://localhost:8080/api/v1/admin/ops/ws/qps
+```
+
+#### 开发模式
+
+```bash
+# 后端（支持热重载）
+cd backend
+go run ./cmd/server
+
+# 前端（支持热重载）
+cd frontend
+pnpm run dev
+```
+
+#### 代码生成
+
+修改 `backend/ent/schema` 后，需要重新生成 Ent + Wire：
+
+```bash
+cd backend
+go generate ./ent
+go generate ./cmd/server
+```
+
+---
+
+## 简易模式
+
+简易模式适合个人开发者或内部团队快速使用，不依赖完整 SaaS 功能。
+
+- 启用方式：设置环境变量 `RUN_MODE=simple`
+- 功能差异：隐藏 SaaS 相关功能，跳过计费流程
+- 安全注意事项：生产环境需同时设置 `SIMPLE_MODE_CONFIRM=true` 才允许启动
+
+---
+
+## Antigravity 使用说明
+
+Sub2API 支持 [Antigravity](https://antigravity.so/) 账户，授权后可通过专用端点访问 Claude 和 Gemini 模型。
+
+### 专用端点
+
+| 端点 | 模型 |
+|------|------|
+| `/antigravity/v1/messages` | Claude 模型 |
+| `/antigravity/v1beta/` | Gemini 模型 |
+
+### Claude Code 配置示例
+
+```bash
+export ANTHROPIC_BASE_URL="http://localhost:8080/antigravity"
+export ANTHROPIC_AUTH_TOKEN="sk-xxx"
+```
+
+### 混合调度模式
+
+Antigravity 账户支持可选的**混合调度**功能。开启后，通用端点 `/v1/messages` 和 `/v1beta/` 也会调度该账户。
+
+> **⚠️ 注意**：Anthropic Claude 和 Antigravity Claude **不能在同一上下文中混合使用**，请通过分组功能做好隔离。

+上記ステップ 5 で事前に `config.yaml` を作成しているため、**初回起動時にセットアップウィザードはスキップされます**。サーバーは既存の config を検出して通常モードで直接起動し、この時点では `users` テーブルが空のため、初回ログインは `invalid email or password` を返します。
+
+**管理者アカウントを作成する 2 つの方法:**
+
+1. **推奨 — ウィザードに `config.yaml` を自動生成させる:** 上記ステップ 5 をスキップします（`cp` を実行しない）。`./sub2api` を直接起動し、`http://localhost:8080` にアクセスすると、セットアップウィザードがデータベース・Redis・管理者アカウントの設定を案内し、`config.yaml` を自動生成します。
+
+2. **すでに `config.yaml` を作成してしまった場合:** 初回起動前に一時的に退避してウィザードを発生させ、完了後に戻します:
+   ```bash
+   mv config.yaml config.yaml.bak
+   ./sub2api        # ウィザードが http://localhost:8080 で起動し、新しい config.yaml を生成します
+   # ウィザード完了後、Ctrl+C でサーバーを停止し、設定を復元します:
+   mv config.yaml.bak config.yaml
+   ./sub2api        # 通常モードで再起動し、作成した管理者でログインします
+   ```
+
 ```bash
