+- PostgreSQL 共享服务在独立仓库构建和发布：<https://gitea.nxsir.cn/nanxun/postgresqlfpk>
+- 使用 fnOS 开发者平台提供的官方 `fnpack` 构建；可通过 `FNPACK=/path/to/fnpack` 指定工具路径
+- Live Recorder 与 PostgreSQL 共享服务分别构建为 x86_64 原生 FPK，均不依赖 Docker
+- Live Recorder 直接依赖 `nxsir.postgresql` 和商店版 `nodejs_v22`；fnOS 会通过 `install_dep_apps` 检查并启用依赖
+- PostgreSQL 共享服务只监听 `127.0.0.1:15432`，独立管理界面默认端口为 `15433`
+- 每个应用经回环接入 API 获得独立数据库、独立 SCRAM 角色和随机密码；支持 pgvector
+- PostgreSQL 管理界面有独立管理员登录、客户端/数据库/角色/会话管理、只读 SQL 和手动备份恢复
+- Live Recorder 安装向导会要求设置自身 `admin` 密码，并填写 PostgreSQL 服务的应用接入令牌
+- Live Recorder 1.2.5 仅连接 PostgreSQL 共享服务，不再打包、启动或回退到原内置 PostgreSQL
+- 已删除旧内置 PostgreSQL 自动迁移能力；升级前必须确认应用已经取得共享数据库凭据，遗留数据目录不会被自动删除
+- Node.js 由 fnOS 商店的 `nodejs_v22` 提供，使用 `/var/apps/nodejs_v22/target/bin/node`，Live Recorder FPK 不再内置 Node.js
+- 依赖 fnOS 系统环境同时提供 `ffmpeg` 和 `ffprobe`，安装前请先确认二者可执行
+- Web 管理界面默认使用端口 `18080`
+- PostgreSQL 数据位于其应用持久化目录，手动备份位于共享目录 `postgresql/backups`
+- 录制文件默认保存在 fnOS 共享目录 `liverecorder/records`；可在“设置 → 录制 → 输出根目录”修改
+
+更完整的安装、端口与凭据说明见 [docs/postgresql-migration.md](docs/postgresql-migration.md)。
+其他 fnOS 应用接入共享数据库时，请参考独立仓库的 [fnOS PostgreSQL 共享服务接入指南](https://gitea.nxsir.cn/nanxun/postgresqlfpk/src/branch/main/docs/fnos-postgresql-client-integration.md)。
+
 ## 验证
 
 - `dotnet build LiveRecorder.sln --no-restore -m:1`
 - `npm run build`（frontend 目录）
+- `npm run test:e2e`（frontend 目录，覆盖 1920 / 1552 / 1366 / 1024 / 768 / 390）
 - Docker Compose 完整部署验证通过

-# PostgreSQL 切换与 SQLite 历史数据迁移
+# PostgreSQL 共享服务部署说明
+
+## fnOS 原生部署
+
+fnOS 方案由两个独立 FPK 和一个商店运行时依赖组成：
+
+| 应用 | 默认端口 | 持久化内容 |
+|---|---:|---|
+| `nxsir.postgresql` | 管理界面 `15433`、数据库 `127.0.0.1:15432` | PostgreSQL 数据、凭据散列、审计日志 |
+| `liverecorder` | Web 管理界面 `18080` | 应用日志、签发后的数据库客户端凭据 |
+
+Live Recorder 还依赖商店应用 `nodejs_v22`，并从 `/var/apps/nodejs_v22/target/bin/node` 调用 Node.js 22。FPK 的 `install_dep_apps=nxsir.postgresql:nodejs_v22` 会让 fnOS 检查并启用两个依赖。
+
+安装顺序：
+
+1. 安装 PostgreSQL 共享服务，设置独立管理密码与长度至少 20 位的应用接入令牌。
+2. 安装 Live Recorder，设置应用管理员密码，并填写同一个接入令牌。
+3. Live Recorder 只通过 `127.0.0.1` 注册。共享服务为它创建独立数据库和 SCRAM 角色，随机密码只在注册响应中返回一次。
+4. 注册成功后，接入令牌会从 Live Recorder 持久化目录删除；签发凭据保存在权限为 `0600` 的 `postgres-client.conf`。
+
+Live Recorder 1.2.5 起只使用共享 PostgreSQL，不再打包、启动或回退到旧内置 PostgreSQL，也不再提供旧内置数据库的自动迁移能力。升级前必须确认 `postgres-client.conf` 有效，或在升级向导填写共享服务应用接入令牌。历史版本留下的 `postgres/` 和 `postgres-migration/` 目录不会被应用读取，也不会自动删除。
+
+录制路径默认是 fnOS 共享目录 `liverecorder/records`，也可以在“设置 → 录制 → 输出根目录”修改；路径模板会继续在该根目录下生成平台、主播、日期等层级，已有目录会直接复用，不会重复嵌套。
+
+### 管理与备份
+
+- PostgreSQL 管理面板使用独立 `admin` 会话，不复用 Live Recorder 登录。
+- SQL 工作台只接受单条 `SELECT`、`WITH`、`EXPLAIN`、`SHOW`、`VALUES` 或 `TABLE`，并在只读事务、30 秒超时和 1000 行上限下执行。
+- 自动签发的应用数据库与角色不能在普通数据库/角色页面直接删除，应从客户端页面吊销。
+- 备份仅手动触发，使用 custom-format `pg_dump` 并保存 SHA-256；恢复需要明确输入目标数据库名称确认。
+
+### fnOS 验证
+
+PostgreSQL 共享服务由独立仓库构建和发布：<https://gitea.nxsir.cn/nanxun/postgresqlfpk>。

+  /path/to/nxsir-postgresql-15.1.1-x86_64.fpk
+```
+
+下面保留 Docker/宿主机从旧 SQLite 导入 PostgreSQL 的流程。
 
 这份说明对应当前主线版本：应用正式运行数据库已经切换为 PostgreSQL，SQLite 仅用于一次性历史数据导入。
