 cd Aether
-
-# 2. 配置环境变量

 ```

-### 一键安装（可选部署方式）
+原生 Linux systemd / macOS launchd 安装需先准备 PostgreSQL，将连接串通过 `DATABASE_URL` 传给安装进程，并选择 `--mode single-node`；不再自动创建本地数据库文件。

-安装脚本先从 `aether-rust-pioneer` 分支下载，不依赖 GitHub Release 的 `latest` 脚本地址。运行后会先选择版本，再选择部署方式。
+### Nightly（每日 main 构建）
+
+Nightly workflow 每天从 `main` 的固定 commit 构建并发布滚动的 GitHub Release `nightly`，同时推送多架构 GHCR 镜像 `ghcr.io/fawney19/aether:nightly`。Nightly 是预发布版本，适合验证最新代码，不保证与正式版相同的稳定性。滚动 Release 需要仓库保持关闭 GitHub Release immutability。
+
+安装最新 nightly（PostgreSQL + Redis）：

 ```bash
-curl -fsSL https://raw.githubusercontent.com/fawney19/Aether/aether-rust-pioneer/install.sh | sudo bash
+curl -fsSL https://raw.githubusercontent.com/fawney19/Aether/main/install.sh | sudo bash -s -- --mode compose --channel nightly
 ```

-运行后按提示输入版本和部署方式。固定安装某个 tag 时，版本选择选 `2`，再输入类似 `v0.7.0-rc23` 的 tag。默认会安装最新预发布版本；Docker Compose 模式默认使用 `pre` 镜像通道。
-如果安装目录里已经有配置，脚本会优先复用：Docker Compose 保留已有 `.env`，systemd 保留已有 `/etc/aether/aether-gateway.env`。只有首次生成新配置时才会提示输入管理员密码。
+Docker Compose 用户可在部署目录的 `.env` 中设置 `APP_IMAGE=ghcr.io/fawney19/aether:nightly`，然后运行 `./update.sh` 获取下一次 nightly。二进制部署请沿用已有 PostgreSQL 环境配置，并使用 `--mode single-node --channel nightly` 重新运行安装脚本升级；当前管理后台的在线更新列表只跟踪正式版/RC/Beta，不会自动提示下一次 nightly。

-
-安装后的常用命令：
+依赖 Docker、Rust toolchain、Node.js 和 make。
+首次启动前需要在 `.env` 中设置 `ADMIN_PASSWORD`，用于创建本地管理员。

 ```bash
-sudo systemctl status aether-gateway --no-pager
-sudo journalctl -u aether-gateway -f
-sudo systemctl restart aether-gateway
+make dev
 ```

-默认单机数据和日志都在安装目录内：
-
-```text
-/opt/aether/data/aether.db
-/opt/aether/logs
-```
-
-多节点不能使用 SQLite 或 `AETHER_RUNTIME_BACKEND=memory`。如果先只生成了多节点模板，编辑 `/etc/aether/aether-gateway.env` 后重跑安装脚本即可：
-
-```env
-AETHER_GATEWAY_DEPLOYMENT_TOPOLOGY=multi-node
-AETHER_GATEWAY_NODE_ROLE=frontdoor
-DATABASE_URL=postgresql://...
-REDIS_URL=redis://...
-```
-
-### 本地开发
+`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`。
+`make dev` 会先完成后端编译，再开始计算服务健康检查超时。数据库 schema 和必要的派生数据准备也会在启动时自动完成；通常不需要手动区分 migration 与 backfill。升级不会主动重写或清除已有业务历史记录，新写入会直接遵循当前的数据持久化策略。排查或部署前预执行时可使用：

 ```bash
-# 启动依赖
-docker compose -f docker-compose.build.yml up -d postgres redis
-
-# 数据库迁移（仅在已有数据库引入新 migration 时需要）
-./dev.sh --migrate
-
-# 数据回填
-./dev.sh --apply-backfills
-
-# 后端
-./dev.sh
-
-# 前端
-cd frontend && npm install && npm run dev
+make db-status
+make db-prepare
 ```

-`./dev.sh` 现在只保留一种本地模式：
+## Codex 远程协同

-| 角色 | 本地地址 | 说明 |
-|------|----------|------|
-| Rust frontdoor | 默认 `http://localhost:8084` | `aether-gateway`，本地唯一公开入口；实际端口由 `APP_PORT` 控制 |
+`aether-vscodex/` 是独立的 VS Code Codex 协同模块：同步模式跟随 VS Code 官方 Codex 面板当前会话且不另起进程；异步模式使用独立 app-server，让浏览器自行列出、恢复、新建和切换会话。两种模式都能从本机 URL 或 Aether 云端查看输出、发送消息和处理授权，模块内的 Vue 前端提供中英文界面。

-本地默认链路是：
+安装、云端配对和安全边界请参阅 [`aether-vscodex/README.md`](aether-vscodex/README.md)。

-```text
-client -> rust frontdoor (aether-gateway) -> execution_runtime/provider transport
-```
+## Aether Tunnel (可选)

-其中：
-
- `aether-gateway` 负责公开入口、健康检查、格式转换、本地执行 runtime，以及当前已迁到 Rust 的 frontdoor/control/background 路径。
- `./dev.sh` 不再启动 Python 宿主；未下沉到 Rust 的 legacy 路由会直接失败。
- `./dev.sh --migrate` 会复用 `.env` 里的数据库配置，显式执行一次数据库迁移后退出。
- `./dev.sh` 默认把 `AETHER_GATEWAY_VIDEO_TASK_TRUTH_SOURCE_MODE` 设为 `rust-authoritative`，避免本地还依赖 Python sync report 语义。
- 空库首次启动会自动初始化到当前 baseline。
- `aether-gateway` 默认启动不会自动应用后续 schema migration；如果数据库版本落后，服务会拒绝启动，并提示先执行 `aether-gateway --migrate`。
- 仓库自带的 `docker-compose.yml` 和 `docker-compose.build.yml` 都已把 `AETHER_GATEWAY_AUTO_PREPARE_DATABASE` 设为默认开启，因此无论是预构建镜像部署还是 `./deploy.sh` / 本地构建 compose，常规启动都会在监听端口前自动执行挂起的 migration 和 backfill。

 ## 环境变量

-部署建议：
-
- Docker Compose：根目录 [`.env.example`](.env.example)
- systemd 二进制部署：使用根目录 `install.sh` 生成 `/etc/aether/aether-gateway.env`
-
-当前主链路真正要关注的是这组变量：
-
 - `APP_PORT`：`aether-gateway` 唯一监听端口，固定绑定 `0.0.0.0:${APP_PORT}`
- `AETHER_DATABASE_DRIVER` / `AETHER_DATABASE_URL`：二进制单机部署可用 `sqlite`，例如 `sqlite:///opt/aether/data/aether.db`
- `DATABASE_URL` / `REDIS_URL`：`aether-gateway` 直接读取的共享后端连接串；多节点必须配置共享数据库和 Redis
- `AETHER_RUNTIME_BACKEND=memory|redis`：单机 SQLite 默认用 `memory`；多节点必须用 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` 和 `docker-compose.build.yml` 默认开启
+- `DATABASE_URL`：PostgreSQL 连接串，例如 `postgresql://USER:PASSWORD@HOST: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 PostgreSQL 按每核 `4` 条自动推导，总池范围为 `32-100`。该预算按进程计算，多实例部署应按数据库连接上限显式分配
+- `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`：可选的请求体完整读取超时；默认或显式设为 `0` 时关闭，非零值限制在 `1000-600000ms`
+- `AETHER_MAX_REQUEST_BODY_MB`：单请求解压后请求体上限，默认 `256MB`；显式设为 `0` 表示不再收紧默认值，但仍受 `256MB` 安全硬上限约束
+- `AETHER_MAX_INTERNAL_BUFFERED_BODY_MB`：heartbeat、管理探测等内部整包响应体上限，默认 `64MB`；显式设为 `0` 表示不再收紧默认值，但仍受 `256MB` 安全硬上限约束
+- `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_TUNNEL_RELAY_ALLOW_PRIVATE_TARGETS`：跨网关 owner relay 解析到私有/保留地址时的显式运维开关，默认关闭；仅当多网关 relay URL 是受控的内网 HTTPS 地址时设置为 `true`。它不改变普通 provider 请求的 DNS/代理策略，也不允许明文 HTTP 非 loopback relay
+- `AETHER_TUNNEL_RELAY_PRIVATE_HOST_ALLOWLIST`：更窄的 owner relay 私网例外，填写逗号分隔的精确主机名（例如 `gateway-a.internal,gateway-b.internal`，忽略大小写和末尾点）；仅这些主机解析出的私有地址会被允许，并且请求仍使用解析后地址 pin。不要填写通配符或 `.internal` 这类后缀
+- `AETHER_INTERNAL_GATEWAY_AUTH_SECRET`：旧版 `/api/internal/gateway/*` 高权限控制面的独立 HMAC 密钥，至少 `32` 字节；未配置时该控制面返回 `404`。不要复用 JWT、数据加密或 tunnel relay 密钥，多节点必须使用同一值及共享 Redis 防重放
+- `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`：PII 恢复同步响应缓冲上限，默认 `64MB`；显式设为 `0` 表示不再收紧默认值，但仍受 `256MB` 安全硬上限约束
+- `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。配置 Redis 时使用 `redis`，否则使用 `memory`；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_DATABASE_MODE=auto|verify-only`：数据库启动策略，默认 `auto`，自动完成挂起的 schema migration 和 backfill；`verify-only` 仅检查并在数据库落后时拒绝启动
+- `AETHER_GATEWAY_AUTO_PREPARE_DATABASE`：旧版兼容开关；新配置请使用 `AETHER_GATEWAY_DATABASE_MODE`
 - `JWT_SECRET_KEY` / `ENCRYPTION_KEY`：认证和敏感数据加密所需密钥
+- `AETHER_BACKUP_ENCRYPTION_KEY`：推荐的 S3 备份独立加密密钥；缺省回退到 `ENCRYPTION_KEY`。新备份使用带 key ID 的 AES-256-GCM v2 envelope，轮换前必须保留旧密钥
 - `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 `*`
- `AETHER_GATEWAY_DEPLOYMENT_TOPOLOGY=single-node|multi-node`
- `AETHER_GATEWAY_NODE_ROLE=all|frontdoor|background`
 - `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`
+- `DB_PASSWORD` / `REDIS_PASSWORD`：Docker Compose 后端密码，首次安装时分别随机生成；手工部署必须替换示例占位值，不要互相复用

-systemd 的 `.env` 必须保持简单 `KEY=VALUE` 形式，不要写 `export`、`${VAR}` 或命令替换。
+### S3 备份离线恢复

-## 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）：**
+先从 S3 下载完整的 `.json.zst.aes256gcm` 对象，再使用原始的完整 S3 object key 做认证解密。恢复工具只验证并输出本地 JSON，不会直接写数据库；数据库导入仍应在维护窗口通过管理端完成。

 ```bash
-# Docker Compose:
-# 1. 切回旧镜像 tag / digest
-# 2. 恢复 Postgres 备份
-# 3. 再启动 app
-
-# systemd:
-# 1. 把 /opt/aether/current 切回旧 release
-# 2. systemctl restart aether-gateway
-# 3. 如果升级包含数据库结构变更，再恢复 Postgres 备份
+AETHER_BACKUP_ENCRYPTION_KEY='原备份密钥' \
+  cargo run -p aether-gateway --bin aether-backup-restore -- \
+  --input ./backup.json.zst.aes256gcm \
+  --object-key 'aether/backups/aether-data-backup-20260822-010000.json.zst.aes256gcm' \
+  --output ./restored-backup.json
 ```

-> 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。
+工具默认拒绝覆盖，输出采用原子写并在 Unix 上设置为 `0600`；Unix 可用 `--overwrite` 原子替换，Windows 为避免非原子删除窗口会要求选择新输出路径。密钥不能作为命令行参数。可使用 `AETHER_BACKUP_ENCRYPTION_KEY`、兼容用 `AETHER_GATEWAY_DATA_ENCRYPTION_KEY` / `ENCRYPTION_KEY`、受保护的 `--key-file`，或 `AETHER_BACKUP_KEYRING_FILE`。Keyring JSON 格式为 `{"version":1,"keys":["当前或历史 v2 secret"],"legacy_v1":["旧 v1 secret"]}`；条目也可写成 `{"secret":"..."}`（兼容字段名 `key`）。也可由 `AETHER_BACKUP_HISTORICAL_KEYS_JSON` 提供同一结构。密钥文件必须是非符号链接的普通文件，Unix 下权限需为 `0600` 或更严格。

-**没有备份的情况：**
-
-当前不应该再依赖旧的 `alembic downgrade` 路线。空库首次启动会自动初始化；如果开启 `AETHER_GATEWAY_AUTO_PREPARE_DATABASE=true`（仓库自带的两份 compose 默认都如此），常规服务启动也会自动应用挂起的 migration/backfill。无论是否自动执行，只要本次发布带来了不可逆的数据结构变化，没有备份就不能保证安全回滚。因此升级前强烈建议先备份 `Postgres`。
+默认限制密文为 `512MiB`、解压后 JSON 为 `1GiB`，可通过受限的 `--max-encrypted-mib` / `--max-json-mib` 调整。网关最多扫描同一备份前缀下 10,000 个对象，并且不会自动删除 S3 对象：`backup_s3_retention_count` 只用于报告超出保留数量的清理候选。旧明文备份在创建并验证加密副本后仍会保留，必须通过 bucket lifecycle 或支持版本条件的外部清理工具移除；启用 Versioning 时还需清理 noncurrent versions，Object Lock/retention 可能阻止物理删除。

-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

-
-This migration does two things:
-1. Change new `usage.billing_status` default from `settled` to `pending`.
-2. Repair only the clearly-safe inconsistent historical rows for production:
-   - failed/cancelled zero-cost rows that were marked settled are converted to void
-   - terminal rows missing finalized_at are backfilled from created_at
-
-Ambiguous positive-cost settled rows are intentionally left untouched for manual audit.
-
-All data updates are batched (10000 rows per iteration) to avoid long-held locks
-and excessive WAL generation on large usage tables.

-# Aether - 数据库迁移说明
-
-## 当前版本
-
- **Revision ID**: `aether_baseline`
- **创建日期**: 2025-12-06
- **状态**: 全新基线
-
-## 迁移历史
-
-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
- **wallets**: 统一钱包账户（充值余额/赠款余额/无限制模式）
- **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
-```
