 ```

-### Docker Compose（本地构建镜像）
+### 一键更新
+
+Docker Compose 部署后，可在部署目录直接执行：

 ```bash
-# 1. 克隆代码
-git clone https://github.com/fawney19/Aether.git
-cd Aether
+./update.sh
+```

-# 2. 配置环境变量
-cp .env.example .env
-python generate_keys.py  # 生成密钥, 并将生成的密钥填入 .env
+`update.sh` 会拉取最新 `app` 镜像并重建 `app` 容器，Docker named volumes、`./data` 和 `./logs` 不会被删除。Single Node 部署也可显式指定：

-# 3. 部署 / 更新（自动构建、启动、迁移）
+```bash
+./update.sh --mode single-node
+```
+
+仓库自带的 Docker Compose 默认把应用日志输出到容器 `stdout/stderr`，直接用 `docker compose logs -f app` 查看，并由 Docker 轮转日志，避免正式发布镜像切换到非 root 用户后再被宿主机挂载日志目录的权限问题拖垮启动。如果你确实需要文件日志，需要在 compose 里把 `AETHER_LOG_DESTINATION` 改成 `file|both`，并额外挂载一个容器用户可写的目录到 `/opt/aether/logs`。
+
+管理后台右上角“版本信息”会检测新版本。Docker Compose 部署只提示版本，实际更新继续执行 `./update.sh`；systemd / launchd / 二进制部署才使用后台自更新，流程是下载对应平台的 GitHub Release 包、强制校验 `SHA256SUMS`、解压到 `/opt/aether/releases/<version>`，再切换 `/opt/aether/current` 并退出进程，交给 systemd / launchd 拉起新版本。
+
+源码或本地构建版本不会启用后台在线更新，请继续使用源码更新流程。Docker Compose 用户如果希望“容器重建后也保持镜像层面的新版本”，仍建议定期运行 `./update.sh` 拉取并重建 app 镜像。服务器访问 GitHub 需要代理时，可设置 `AETHER_UPDATE_PROXY_URL`，也兼容 `UPDATE_PROXY_URL`、`HTTPS_PROXY`、`ALL_PROXY`、`HTTP_PROXY` 以及 `NO_PROXY`。共享出口触发 GitHub API 限流时，可设置只读 `AETHER_UPDATE_GITHUB_TOKEN`，也兼容 `GITHUB_TOKEN` / `GH_TOKEN`。下载总超时默认 600 秒，连续无响应/无数据默认 30 秒，可通过 `AETHER_UPDATE_DOWNLOAD_TIMEOUT_SECS` 和 `AETHER_UPDATE_DOWNLOAD_IDLE_TIMEOUT_SECS` 调整。
+
+标准 Docker Compose 使用 Docker named volumes 存放 Postgres/Redis/MySQL 数据；Single Node 使用部署目录下的 `./data` 存放 SQLite 数据。
+
+如果是本地源码构建镜像的部署，继续使用：
+
+```bash
 ./deploy.sh
 ```

-### 本地开发
+如果要在本机联调“管理后台在线更新”本身，可启动仓库内置的 release-layout 测试环境：

 ```bash
-# 启动依赖
-docker compose -f docker-compose.build.yml up -d postgres redis
-
-# 后端
-uv sync
-./dev.sh
-
-# 前端
-cd frontend && npm install && npm run dev
+docker compose -f docker-compose.release-local.yml up -d --build
 ```

-## Aether Proxy
+这套环境会用当前源码构建一个本地测试镜像，但编译为 `release` 类型，并默认伪装成 `v0.7.0`，这样后台会按正式发布版逻辑开放“立即更新”。默认监听 `http://127.0.0.1:18085`，数据目录使用 `./data-release-local`；日志默认走 `docker logs`，不会影响你正在跑的源码构建容器。

-Aether Proxy 是配套的正向代理节点，部署在海外 VPS 上，为墙内的 Aether 实例中转 API 流量。支持 TUI 向导一键配置、systemd 服务管理、TLS 加密、DNS 缓存及连接池调优。
+如果这套容器在 `prepare-update` 时访问 GitHub 失败，而你本机是通过代理出网，请在 `.env` 里把 `AETHER_UPDATE_PROXY_URL` 写成宿主机地址，例如 `http://host.docker.internal:7890`；容器内的 `127.0.0.1` 指向容器自身，不是宿主机。
+
+如果想重置这套联调环境（包括 `/opt/aether/current` 和已下载的历史版本），执行：
+
+```bash
+docker compose -f docker-compose.release-local.yml down -v
+```
+
+可选变量：
+
+- `AETHER_RELEASE_LOCAL_VERSION`：本地联调镜像对外声明的当前版本，默认 `v0.7.0`
+- `AETHER_RELEASE_LOCAL_PORT`：本地联调端口，默认 `18085`
+- `LOCAL_RELEASE_APP_IMAGE`：本地联调镜像名，默认 `aether-app:release-local`
+
+### 一键安装（默认 Single Node：Linux systemd / macOS launchd + SQLite）
+
+```bash
+git clone https://github.com/fawney19/Aether.git
+cd Aether
+curl -fsSL https://raw.githubusercontent.com/fawney19/Aether/main/install.sh | sudo bash
+```
+
+## 本地开发
+
+依赖 Docker、Rust toolchain、Node.js 和 make。
+
+```bash
+make dev
+```
+
+`make dev` 会同时启动后端 `aether-gateway` 和前端 `frontend` 的 Vite dev server。需要单独启动时可使用 `make dev-backend` 或 `make dev-frontend`。
+Postgres / Redis 本地依赖未就绪时，`make dev` 会自动执行 `docker compose up -d postgres redis`。
+
+## Aether Tunnel (可选)
+
+Aether Tunnel 是配套的正向代理节点，部署在海外 VPS 上，为墙内的 Aether 实例中转 API 流量。

 ## 环境变量

-### 必需配置
-
-| 变量 | 说明 |
-|------|------|
-| `DB_PASSWORD` | PostgreSQL 数据库密码 |
-| `REDIS_PASSWORD` | Redis 密码 |
-| `JWT_SECRET_KEY` | JWT 签名密钥（使用 `generate_keys.py` 生成） |
-| `ENCRYPTION_KEY` | API Key 加密密钥（更换后需重新配置 Provider Key） |
-| `ADMIN_EMAIL` | 初始管理员邮箱 |
-| `ADMIN_USERNAME` | 初始管理员用户名 |
-| `ADMIN_PASSWORD` | 初始管理员密码 |
-
-### 可选配置
-
-| 变量 | 默认值 | 说明 |
-|------|--------|------|
-| `APP_PORT` | 8084 | 应用端口 |
-| `API_KEY_PREFIX` | sk | API Key 前缀 |
-| `LOG_LEVEL` | INFO | 日志级别 (DEBUG/INFO/WARNING/ERROR) |

-## Q&A
-
-### Q: 如何开启/关闭请求体记录？
-
-管理员在 **系统设置** 中配置日志记录的详细程度:
-
-| 级别 | 记录内容 |
-|------|----------|
-| Base | 基本请求信息 |
-| Headers | Base + 请求头 |
-| Full | Headers + 请求体 |
-
-### Q: 更新出问题如何回滚？
-
-**有备份的情况（推荐）：**
-
-```bash
-# 1. 停止应用
-docker compose stop app
-
-# 2. 恢复数据库（先清空再导入）
-docker compose exec -T postgres psql -U postgres -c "DROP DATABASE aether; CREATE DATABASE aether;"
-gunzip < backup_xxx.sql.gz | docker compose exec -T postgres psql -U postgres -d aether
-
-# 3. 拉取旧版本镜像并重启
-#    方式一：使用具体版本 tag（如果有发布版本号）
-#    将 docker-compose.yml 中 image 从 ghcr.io/fawney19/aether:latest 改为指定版本
-#    方式二：使用之前记录的镜像 digest
-#    将 image 改为 ghcr.io/fawney19/aether@sha256:xxxxx
-docker compose up -d app
-```
-
-> 可以在升级前通过 `docker inspect ghcr.io/fawney19/aether:latest --format '{{index .RepoDigests 0}}'` 记录当前镜像 digest，方便回滚时使用。
-
-**没有备份的情况：**
-
-```bash
-# 1. 用当前容器回退数据库迁移（回退 1 步，按需调整数字）
-docker compose exec app alembic downgrade -1
-
-# 2. 查看回退后的版本确认正确
-docker compose exec app alembic current
-
-# 3. 切回旧镜像并重启（同上方式修改 docker-compose.yml 中的 image）
-docker compose up -d app
-```
-
-> 注意：没有备份的回滚依赖 alembic downgrade，如果迁移涉及不可逆的数据变更（如删除列），可能无法完全恢复数据。因此强烈建议升级前备份。
+- `APP_PORT`：`aether-gateway` 唯一监听端口，固定绑定 `0.0.0.0:${APP_PORT}`
+- `DATABASE_URL`：数据库连接串；SQLite 例如 `sqlite:///opt/aether/data/aether.db`，Postgres 例如 `postgresql://postgres:aether@postgres:5432/aether`
+- `AETHER_GATEWAY_DATA_POSTGRES_MIN_CONNECTIONS` / `AETHER_GATEWAY_DATA_POSTGRES_MAX_CONNECTIONS`：数据库连接池手动覆盖值；未配置时会自动推导，SQLite 固定 `1/1`，Postgres/MySQL 按 CPU 核心数计算并默认封顶 `100`
+- `AETHER_GATEWAY_MAX_IN_FLIGHT_REQUESTS`：单实例请求并发上限；未配置时按 CPU 自动推导（基础范围 `512-65536`），低文件描述符预算时会进一步下调
+- `AETHER_GATEWAY_REQUEST_BODY_BUFFER_BUDGET_MB`：单实例同时读取和解压请求体的加权内存预算，默认 `256MB`
+- `AETHER_GATEWAY_REQUEST_BODY_READ_TIMEOUT_MS`：请求体完整读取超时，默认 `120000ms`
+- `AETHER_MAX_REQUEST_BODY_MB`：可选的单请求解压后请求体上限；未配置或设为 `0` 时不限制
+- `AETHER_MAX_INTERNAL_BUFFERED_BODY_MB`：可选的 heartbeat、管理探测等内部整包响应体上限；未配置或设为 `0` 时不限制
+- `AETHER_TUNNEL_NODE_STATUS_QUEUE_CAPACITY`：隧道节点状态上报队列容量，默认 `1024`；满载时拒绝新事件，避免控制面故障导致无界内存增长
+- `AETHER_GATEWAY_SECURITY_CACHE_TTL_MS`：IP 黑白名单本地缓存时间，默认 `1000ms`，写操作会主动失效相关缓存
+- `AETHER_MAX_REDACTED_SYNC_RESPONSE_BODY_MB`：可选的 PII 恢复同步响应缓冲上限；未配置或设为 `0` 时不限制
+- `REDIS_URL`：Redis 连接串；仅 Postgres + Redis 的 Docker Compose 部署需要配置
+- `AETHER_RUNTIME_BACKEND=memory|redis`：运行时缓存/协调后端。SQLite 默认用 `memory`，不会连接 Redis；多节点部署和需要跨 gateway 重启恢复 OpenAI Responses continuation history 的部署必须使用共享 Redis
+- `AETHER_GATEWAY_AUTO_PREPARE_DATABASE`：常规启动前自动执行挂起的 schema migration 和 backfill；仓库自带的 `docker-compose.yml` 默认开启
+- `JWT_SECRET_KEY` / `ENCRYPTION_KEY`：认证和敏感数据加密所需密钥
+- `API_KEY_PREFIX`：用户和管理员新建 API Key 时使用的前缀，默认 `sk`
+- `ADMIN_USERNAME` / `ADMIN_PASSWORD` / `ADMIN_EMAIL`：首次启动时自举首个本地管理员；`install.sh` 会提示输入管理员密码
+- `CORS_ORIGINS` / `CORS_ALLOW_CREDENTIALS`：前端跨域来源控制；如果要跨域带登录 Cookie，`CORS_ORIGINS` 不能写 `*`
+- `RUST_LOG`：Rust 日志过滤，例如 `aether_gateway=info`、`aether_gateway=debug,sqlx=warn`
+- Docker Compose 的 `DB_PASSWORD` / `REDIS_PASSWORD` 默认使用 `aether`

-Revision ID: m4n5o6p7q8r9
-Revises: 02a45b66b7c4
-Create Date: 2026-01-10 20:00:00.000000
-
-This migration consolidates all schema changes from 2026-01-08 to 2026-01-10:
-
-1. provider_api_keys: Key 直接关联 Provider (provider_id, api_formats)
-2. provider_api_keys: 添加 rate_multipliers JSON 字段（按格式费率）
-3. models: global_model_id 改为可空（支持独立 ProviderModel）
-4. providers: 添加 timeout, max_retries, proxy（从 endpoint 迁移）
-5. providers: display_name 重命名为 name，删除原 name
-6. provider_api_keys: max_concurrent -> rpm_limit（并发改 RPM）
-7. provider_api_keys: 健康度改为按格式存储（health_by_format, circuit_breaker_by_format）
-8. provider_endpoints: 删除废弃的 rate_limit 列
-9. usage: 添加 client_response_headers 字段
-10. provider_api_keys: 删除 endpoint_id（Key 不再与 Endpoint 绑定）
-11. provider_endpoints: 删除废弃的 max_concurrent 列
-12. providers: 删除废弃的 rpm_limit, rpm_used, rpm_reset_at 列

-
-所有历史增量迁移已清理，当前以完整 schema 作为新起点。
-
-## 核心数据库结构
-
-### 用户系统
- **users**: 用户账户管理
- **api_keys**: API 密钥管理
- **user_quotas**: 用户配额管理
- **user_preferences**: 用户偏好设置
-
-### Provider 三层架构
- **providers**: LLM 提供商配置
- **provider_endpoints**: Provider 的 API 端点配置
- **provider_api_keys**: Endpoint 的具体 API 密钥
- **api_key_provider_mappings**: 用户 API Key 到 Provider 的映射关系
-
-### 模型系统
- **global_models**: 统一模型定义（GlobalModel）
- **models**: Provider 的模型实现和价格配置
- **model_mappings**: 统一的别名与降级映射表
-
-### 监控和追踪
- **usage**: API 使用记录
- **request_candidates**: 请求候选记录
- **provider_usage_tracking**: Provider 使用统计
- **audit_logs**: 系统审计日志
-
-### 系统功能
- **announcements**: 系统公告
- **announcement_reads**: 公告阅读记录
- **system_configs**: 系统配置
-
-## 从旧数据库迁移
-
-如需从旧数据库迁移数据，请使用迁移脚本：
-
-```bash
-# 设置环境变量
-export OLD_DATABASE_URL="postgresql://user:pass@old-host:5432/old_db"
-export NEW_DATABASE_URL="postgresql://user:pass@new-host:5432/aether"
-
-# 干运行（查看迁移量）
-python scripts/migrate_data.py --dry-run
-
-# 执行迁移
-python scripts/migrate_data.py
-
-# 只迁移特定表
-python scripts/migrate_data.py --tables users,providers,api_keys
-
-# 跳过大表
-python scripts/migrate_data.py --skip usage,audit_logs
-```
-
-## 新数据库初始化
-
-```bash
-# 1. 运行迁移创建表结构
-DATABASE_URL="postgresql://user:pass@host:5432/aether" uv run alembic upgrade head
-
-# 2. 初始化管理员账户
-python -m src.database.init_db
-```
-
-## 未来迁移
-
-基于 `aether_baseline` 创建增量迁移：
-
-```bash
-# 修改模型后，生成新的迁移
-DATABASE_URL="..." uv run alembic revision --autogenerate -m "描述变更"
-
-# 应用迁移
-DATABASE_URL="..." uv run alembic upgrade head
-```
