-# go-vue-template
+# Atlas
 
-Go + Vue 单体应用脚手架。一个二进制同时提供 REST API 与管理台 UI，前端通过 `go:embed` 嵌入，适合内部工具、管理后台、网关控制台等场景。
+Atlas 是面向 AI 能力的统一接入与使用平台。Go + Vue 单体部署：用户端提供对话、文生图、图生图与历史记录；管理端配置上游 Provider 与模型、查看请求日志；内部 Gateway 兼容 OpenAI / Replicate 协议，统一编排、日志与路由。
 
 ## 特性
 
 - **单体部署**：API 与 SPA 同进程、同端口，生产环境无需 Node.js
-- **分层清晰**：`cmd` → `api` → `service` → `store`，职责边界明确
+- **多协议 Gateway**：`/v1/*` 透传 OpenAI（Chat、Embeddings 等）与 Replicate（Predictions）
-- **开箱即用**：登录鉴权、设置页、审计日志、i18n、Docker 多阶段构建
+- **统一 invoke 编排**：同步/异步调用、任务队列、上游轮询 + 前端 SSE 进度推送
-- **纯 Go 编译**：SQLite 使用 `modernc.org/sqlite`，`CGO_ENABLED=0` 可交叉编译
+- **Provider 管理**：管理端配置上游地址与密钥；模型优先从上游 `/v1/models` 同步，也可手动维护
-- **可演进**：goose SQL 迁移、settings KV 配置、Pinia 状态管理
+- **请求日志**：Gateway 与用户 invoke 全链路记录，管理端可检索
+- **用户会话隔离**：Cookie 会话区分用户数据；管理端独立 Bearer 鉴权
+- **SQLite**：使用 `mattn/go-sqlite3`（CGO），编译远快于纯 Go 的 modernc 驱动；Docker/CI 镜像内已安装 `gcc`

+
+```
+浏览器 → POST /api/v1/user/conversations/:id/messages
+       → chat.Service → provider.ProxyStream → 上游 SSE 真流式回传
+```
+
+**生图（异步任务）**
+
+```
+浏览器 → POST /api/v1/user/generate
+       → invoke.Service 创建 task → async_worker 轮询上游
+       → GET /api/v1/user/tasks/:id/events (SSE) 推送进度
+```
+
+**Gateway 直连**
+
+```
+客户端 → /v1/chat/completions | /v1/predictions ...
+       → provider.Router 按模型路由 → 上游 + request_logs
 ```
 
 ### 分层约定
 
 | 层 | 路径 | 职责 |
 |----|------|------|
-| 入口 | `cmd/app/` | 解析参数、初始化依赖、启动 HTTP、优雅关闭 |
+| 入口 | `cmd/app/` | 参数解析、依赖初始化、HTTP 服务、优雅关闭 |
-| HTTP | `internal/api/` | 路由注册、中间件、请求/响应、SPA 静态服务 |
+| HTTP | `internal/api/` | 路由、中间件、用户/管理/Gateway Handler、SPA |
-| 业务 | `internal/service/` | 跨模块编排，注入 Store 与领域服务 |
+| 编排 | `internal/service/` | invoke、chat、reqlog、taskevents、asset |
-| 持久化 | `internal/store/` | 数据库连接、迁移、仓储方法 |
+| 上游 | `internal/provider/` | HTTP 代理、模型列表、流式转发、Provider 路由 |
-| 配置 | `internal/settings/` | 配置键常量、默认值、展示脱敏、提交校验 |
+| 领域 | `internal/domain/` | 服务类型、invoke 请求/响应模型 |
-| 前端 | `web/` | Vue SPA 源码，构建产物复制到 `internal/api/static/` |
+| 持久化 | `internal/store/` | SQLite、goose 迁移、仓储与 HotCache |
-
+| 配置 | `internal/settings/` | KV 配置键、默认值、脱敏 |
-**原则：**
+| 前端 | `web/` | Vue SPA，构建产物嵌入 `internal/api/static/` |
-- Handler 只做 HTTP 适配，不写复杂业务逻辑
-- Store 封装 SQL，不暴露 `*sql.DB` 给 Handler
-- 前端构建产物不提交 dist，仅保留 `static/index.html` 占位以保证 `go test` / CI 可通过

-## API 规范
+## 功能模块
+
+### 用户端（`/chat`、`/image/*`、`/history`）
+
+- 多轮对话，SSE 流式输出
+- 文生图、图生图（异步任务 + SSE 进度）
+- 生成历史、参数预设
+- 基于 `Atlas-Session` Cookie 的会话隔离
+
+### 管理端（`/admin/*`）
+
+- Provider CRUD（OpenAI / Replicate 协议、base_url、api_key）
+- 模型列表：上游 sync 或手动添加
+- 请求日志检索、仪表盘统计
+- 系统设置（应用名、鉴权、语言等）
+
+### Gateway（`/v1/*`）
+
+| 协议 | 路由示例 |
+|------|----------|
+| OpenAI | `GET /v1/models`、`POST /v1/chat/completions`、`POST /v1/embeddings` … |
+| Replicate | `POST /v1/predictions`、`GET /v1/predictions/:id`、`GET /v1/predictions/:id/stream` … |
+
+Gateway 使用与用户端相同的 Cookie 会话，按模型名路由到已配置的 Provider。
+
+---
+
+## API 概览
 
 **前缀：** `/api/v1`
 
-### 鉴权
+### 鉴权（管理端）
 
 | 接口 | 说明 |
 |------|------|
 | `POST /api/v1/auth/login` | 登录，返回 `{ "token": "..." }` |
-| `GET /api/v1/auth/status` | 查询 `{ "enabled": true \| false }` |
+| `GET /api/v1/auth/status` | `{ "enabled": true \| false }` |
 | 受保护路由 | Header: `Authorization: Bearer <token>` |
 
-当 `auth_enabled` 不为 `"true"` 时，受保护路由跳过鉴权（便于本地调试）。
+当 `auth_enabled` 不为 `"true"` 时，管理端路由跳过鉴权（便于本地调试）。用户端路由始终公开，通过 Cookie 区分会话。
+
+### 用户端（节选）
+
+| 方法 | 路径 | 说明 |
+|------|------|------|
+| POST | `/user/session` | 初始化会话 |
+| GET | `/user/meta` | 可用模型与服务元信息 |
+| * | `/user/conversations/*` | 对话 CRUD 与消息 |
+| POST | `/user/generate` | 文生图 / 图生图 |
+| POST | `/user/upload` | 上传参考图 |
+| GET | `/user/tasks/:id/events` | 任务进度 SSE |
+| * | `/user/generations/*`、`/user/presets/*` | 历史与预设 |
+
+### 管理端（节选）
+
+| 方法 | 路径 | 说明 |
+|------|------|------|
+| * | `/admin/providers/*` | Provider 与模型管理 |
+| POST | `/admin/providers/:id/models/sync` | 从上游同步模型 |
+| GET | `/admin/logs` | 请求日志 |
+| GET | `/admin/dashboard/stats` | 统计 |
 
 ### 响应格式
 
 ```json
-// 成功 — 按场景选用
 { "ok": true }
 { "items": [...], "total": 42 }
-{ "app_name": "App", "data_dir": "./data" }

-// 错误 — 统一字段
 { "error": "human readable message" }
 ```
 
-### HTTP 状态码

-
-| 码 | 含义 |

-### 双进程开发（推荐）

 # 终端 1 — 后端
 make run
 
 # 终端 2 — 前端热更新
 make dev-web
-# 浏览器访问 http://localhost:5173
+# 浏览器 http://localhost:5173
 ```
 
-Vite 将 `/api` 代理到 `http://127.0.0.1:8080`。

-### 单体构建
-
-```bash
-make build
-# 1. web: npm run build → web/dist
-# 2. cp web/dist/* → internal/api/static/
-# 3. go build → dist/app（embed 前端）

-## 扩展指南
+## UI 设计
 
-### 新增 REST 接口
+前端样式与布局规范见 [docs/UI-DESIGN-SYSTEM.md](docs/UI-DESIGN-SYSTEM.md)。页面统一使用 `PageHeader`、`AppCard`、`StatCard` 等壳层组件，品牌色与间距 Token 定义在 `web/src/styles/global.css`。
-
-1. `internal/store/migrations/00N_*.sql` — 建表或改表
-2. `internal/store/store.go` — 仓储方法
-3. `internal/api/handlers.go` — 注册路由与 Handler
-4. `web/src/api/client.ts` — 类型定义与 API 调用
-5. `web/src/views/` + `web/src/router/index.ts` — 页面与路由
-
-### 新增业务模块
-
-在 `internal/` 下新建包（如 `internal/worker/`），在 `service.App` 中注入，由 `api` 层调用。保持 Handler 薄、领域逻辑内聚。
-
-### 前端规范
-
-- 页面使用 `PageHeader` + `AppCard` 布局
-- 样式变量定义在 `web/src/styles/theme.css`
-- 文案走 `vue-i18n`，避免硬编码
-- API 调用统一经 `web/src/api/client.ts`
