chore: bump version to 0.0.74 [skip ci]

Remove UI options for features that no longer exist:
- qB download auto-organize
- downloader smart classification
- seeding (keep seeding)

Also remove related warning banners and simplify move transfer labels.

 ## 项目简介
 
-MMTL 是一个自托管媒体管理系统，面向 NAS、小主机、家庭影音和多用户共享场景。它把媒体库、刮削、下载整理、订阅、网盘播放、Emby 协议兼容、用户权限和 Bot 通知放在一个后台里，目标是让用户只维护一套服务，就能给网页端、手机端、电视端和第三方播放器使用。
+**MMTL** 是一个自托管私人媒体管理系统，适合 NAS、小主机、家庭共享和多端播放场景。本项目由 [MediaStationGo](https://github.com/ShukeBta/MediaStationGo) fork 并持续二开维护，在保留「一套服务覆盖网页、手机、电视与第三方播放器」思路的同时，围绕网盘播放、任务队列、远程挂载和权限体系做了大量增强。
 
-核心能力：
+你可以把 MMTL 理解为：
+
+- 一个带现代 Web UI 的**媒体库后台**
+- 一个兼容 Emby/Jellyfin 客户端的**协议网关**
+- 一个连接本地硬盘、下载目录与网盘存储的**整理与播放入口**
+
+### 核心能力
+
+| 模块 | 说明 |
+| --- | --- |
+| **媒体库** | 电影、电视剧、动漫、综艺、音乐与自定义库；多根目录、扫库、海报墙、继续观看 |
+| **元数据刮削** | TMDb、Bangumi、Douban、TheTVDB、Fanart 等；支持 NFO、手动匹配、刮削队列 |
+| **播放** | 网页播放器、HLS 转码、弹幕、字幕、播放配置档、观看历史与收藏 |
+| **Emby 协议** | Infuse、SenPlayer、Fileball 等客户端可直接添加本服务，使用 MMTL 账号登录 |
+| **远程 Emby 挂载** | 将远程 Emby 媒体库挂载到本地界面统一浏览（无需单独开 Emby 客户端） |
+| **网盘与 STRM** | OpenList、CloudDrive2、115、WebDAV 等；STRM 同步、上传/下载队列、直链/302 播放 |
+| **下载与整理** | qBittorrent 接入、站点搜索与订阅、下载后自动整理、文件管理器（复制/移动/硬链/软链） |
+| **用户与权限** | 管理员/普通用户、有效期、成人内容开关、播放配置 PIN、细粒度操作权限 |
+| **运维能力** | 统一任务队列、回收站、存储统计、DLNA 投屏、系统设置与日志 |
+
+### 技术栈
+
+- **后端**：Go · Gin · GORM · SQLite / PostgreSQL · 可选 Redis · 可选 OpenSearch
+- **前端**：React 18 · Vite · TypeScript · Tailwind CSS · Zustand
+- **部署**：Docker Compose 多档模板，支持 amd64 / arm64 镜像与单文件可执行发布
+
+---
 
-- **媒体库管理**：电影、电视剧、动漫、综艺、音乐和自定义媒体库统一管理。
-- **Emby 协议兼容**：Infuse、VidHub、SenPlayer、Fileball 等客户端可按 Emby/Jellyfin 方式添加服务器。
-- **本地 + 网盘**：支持本地硬盘、下载目录、OpenList、CloudDrive2、WebDAV、STRMURL 和 302 反代播放。
-- **订阅下载入库**：连接 qBittorrent 后支持搜索、订阅、下载完成整理、刮削和入库通知。
-- **多用户与权限**：管理员/普通用户、有效期、成人内容开关、设备管理、注册码和 Telegram Bot 绑定。
-- **灵活部署**：单镜像 SQLite 一键起步，或按规模选择 PostgreSQL、Redis、OpenSearch，低配 NAS 到大库检索都能覆盖。
 ## 快速开始
 
-最推荐使用 Docker Compose。仓库提供四份独立完整模板，全部不依赖 `.env`。想最省心就下载单镜像档（SQLite，只有一个镜像）；只需要按需修改访问端口、媒体目录、下载目录和可选硬件设备。需要多用户/高并发再选第一档起的 PostgreSQL 档位。
+推荐使用 Docker Compose。仓库提供四份**互相独立**的完整模板，无需 `.env` 即可起步。
 
 ```bash
-mkdir -p MMTL
-cd MMTL
-# 最省心：单镜像 + SQLite，只启动一个容器
+mkdir -p MMTL && cd MMTL
+
+# 最省心：单镜像 + 内置 SQLite
 curl -fsSL https://raw.githubusercontent.com/truewhile/MMTL/main/docker-compose.simple.yml -o docker-compose.yml
-# 或第一档：PostgreSQL（多用户/高并发更稳）
+
+# 或多用户场景：PostgreSQL 第一档
 # curl -fsSL https://raw.githubusercontent.com/truewhile/MMTL/main/docker-compose.yml -o docker-compose.yml
+
 docker compose up -d
 ```
 
-启动后访问：
+浏览器访问：
 
 ```text
 http://服务器IP:18080
 ```
 
-默认账号：
-
-```text
-admin / admin123
-```
-
-首次登录后请立刻修改管理员密码。
+默认账号：`admin` / `admin123`（首次登录后请立即修改密码）
 
 镜像地址：
 
 ```text
-GHCR：ghcr.io/truewhile/mmtl:latest
+ghcr.io/truewhile/mmtl:latest
 ```
 
+---
+
 ## 部署档位
 
-MMTL 推荐按机器资源和用户规模选择部署档位。每份 Compose 文件都是完整文件，不需要再叠加多个 `-f`。想一个镜像跑起来就选单镜像档（SQLite）；需要多用户 / 高并发时再用 PostgreSQL 三档。Redis 和 OpenSearch 是增强组件，不替代 PostgreSQL。
+按机器资源选择档位。每份 Compose 文件均可单独使用，**不要**叠加多个 `-f`。
 
-| 档位 | 完整配置文件 | 组件 | 适合场景 |
+| 档位 | 配置文件 | 组件 | 适合场景 |
 | --- | --- | --- | --- |
-| 单镜像档 | `docker-compose.simple.yml` | MMTL + 内置 SQLite | 新手、单人使用、只想一个镜像跑起来的低配机器 |
-| 第一档 | `docker-compose.yml` | MMTL + PostgreSQL | 大多数 NAS、个人/家庭使用、低内存机器 |
-| 第二档 | `docker-compose.standard.yml` | MMTL + PostgreSQL + Redis | 多用户、Emby 客户端频繁刷新、首页/媒体列表访问较多 |
-| 第三档 | `docker-compose.search.yml` | MMTL + PostgreSQL + Redis + OpenSearch | 超大媒体库、复杂全文搜索、后续需要独立搜索索引 |
+| 单镜像档 | `docker-compose.simple.yml` | MMTL + SQLite | 新手、单人、低配 NAS，只想一个容器跑起来 |
+| 第一档 | `docker-compose.yml` | MMTL + PostgreSQL | 大多数家庭 NAS，多用户更稳 |
+| 第二档 | `docker-compose.standard.yml` | + Redis | 多用户、Emby 客户端频繁刷新、首页/列表访问多 |
+| 第三档 | `docker-compose.search.yml` | + OpenSearch | 超大媒体库、复杂全文搜索（内存占用更高） |
 
-### 单镜像档：SQLite（最省心）
+### 单镜像档要点
 
-只启动 MMTL 一个镜像，主数据库用内置 SQLite，不需要 PostgreSQL / Redis / `.env`。变量最少、资源占用最低，适合新手和单人使用。日后需要多用户或更高并发时，保留 `./data` 后切换到第一档的 PostgreSQL 即可。
-
-```bash
-mkdir -p MMTL
-cd MMTL
-curl -fsSL https://raw.githubusercontent.com/truewhile/MMTL/main/docker-compose.simple.yml -o docker-compose.yml
-docker compose up -d
-```
-
-第一次部署通常只需要改 `docker-compose.yml` 里的这几处：
+- 只启动 **一个** MMTL 容器，数据在 `./data/mmtl.db`
+- 通常只需改端口与媒体目录挂载
+- **不要**设置 `MMTL_DATABASE_DSN`，否则会切到 PostgreSQL
 
 ```yaml
 ports:
-  - "18080:8080"          # 改左边 18080 即可
+  - "18080:8080"
 volumes:
   - ./data:/data          # 必须备份
-  - ./media:/media        # 改左边为你的媒体目录，例如 /vol1/1000/Media:/media
-  # - /dev/dri:/dev/dri   # Intel 核显硬解需要时取消注释
+  - ./cache:/cache        # 可重建
+  - ./media:/media        # 改成你的媒体目录
 ```
 
-网页后台添加媒体库时填写容器内路径：
+网页添加媒体库时填写容器内路径，例如 `/media`、`/media/电影`。
 
-```text
-/media
-/media/电影
-/media/电视剧
-```
+### PostgreSQL 档位要点
 
-关键数据目录：
-
-```text
-./data       JWT 密钥、运行配置、SQLite 主数据库（mmtl.db）——必须备份
-./cache      海报/临时缓存，可重建
-./media      媒体库
-```
-
-> 单镜像模式请不要配置 `MMTL_DATABASE_DSN`；一旦填了 DSN 就会切回 PostgreSQL。
-
-### 第一档：PostgreSQL
-
-第一档是默认推荐部署。它只启动主服务和 PostgreSQL，资源占用最低，适合绝大多数 NAS。
-
-```bash
-mkdir -p MMTL
-cd MMTL
-curl -fsSL https://raw.githubusercontent.com/truewhile/MMTL/main/docker-compose.yml -o docker-compose.yml
-docker compose up -d

-```text
-./postgres   PostgreSQL 主数据库，必须备份
-./data       JWT 密钥、运行配置、旧 SQLite 迁移源
-./cache      海报、临时文件、转码缓存，可删除重建
-```
-
-### 第二档：PostgreSQL + Redis
-
-第二档是独立完整文件，包含第一档全部配置并额外启用 Redis。Redis 用作热缓存，能减轻多用户和 Emby 客户端频繁刷新时的数据库压力。
-
-```bash
-mkdir -p MMTL
-cd MMTL
-curl -fsSL https://raw.githubusercontent.com/truewhile/MMTL/main/docker-compose.standard.yml -o docker-compose.yml
-docker compose up -d
-```
-
-Redis 数据目录是 `./redis`。它主要保存缓存，通常可重建；真正需要备份的仍然是 `./postgres` 和 `./data`。
-
-### 第三档：PostgreSQL + Redis + OpenSearch
-
-第三档是独立完整文件，包含第二档全部配置并额外启用 OpenSearch，用于大库全文搜索和独立搜索索引。OpenSearch 常驻内存明显更高，低配 NAS 不建议开启。
-
-```bash
-mkdir -p MMTL
-cd MMTL
-curl -fsSL https://raw.githubusercontent.com/truewhile/MMTL/main/docker-compose.search.yml -o docker-compose.yml
-docker compose up -d
-```
-
-OpenSearch 数据目录是 `./opensearch`。搜索索引可重建，但重建大库索引会花时间；机器资源足够时再开启第三档。
-
-## 配置示例
-
-仓库内提供四份推荐 Compose 文件：
-
-```text
-docker-compose.simple.yml     单镜像档：MMTL + 内置 SQLite
-docker-compose.yml            第一档：MMTL + PostgreSQL
-docker-compose.standard.yml   第二档：MMTL + PostgreSQL + Redis
-docker-compose.search.yml     第三档：MMTL + PostgreSQL + Redis + OpenSearch
-```
-
-仓库只保留面向用户部署和项目维护的必要文件。旧的本地部署脚本、发包脚本、开发机辅助脚本、`.env` 示例和旧高级 Compose 模板已经移除；Linux / Docker 用户按上面四个 Compose 文件部署即可。开发者本地生成的 `bin/`、`data/`、`cache/`、`logs/`、`.tmp/`、`tools/` 等目录已列入 `.gitignore`，不应提交到仓库。
-
-如果直接下载为 `docker-compose.yml`，启动命令统一是：
-
-```bash
-docker compose up -d
-```
-
-如果保留原始文件名，也可以这样启动：
-
-```bash
-docker compose -f docker-compose.simple.yml up -d
-docker compose -f docker-compose.standard.yml up -d
-docker compose -f docker-compose.search.yml up -d
-```
-
-常用配置片段如下，注释保留为中文，方便直接复制到 NAS 上调整：
+- 主库在 `./postgres`，配置与密钥在 `./data`
+- 若存在旧版 `./data/mmtl.db`，首次启动会自动迁移到 PostgreSQL
+- 迁移完成后可将 `MMTL_DATABASE_DB_PATH` 改为不存在路径，避免重复检查：
 
 ```yaml
-services:
-  mmtl:
-    image: ghcr.io/truewhile/MMTL:latest
-    ports:
-      # 左边是宿主机访问端口，右边是容器内端口。
-      - "18080:8080"
-    volumes:
-      # 运行数据：JWT 密钥、配置、旧 SQLite 迁移源。
-      - ./data:/data
-
-      # 缓存目录：海报、临时文件、转码缓存，可删除重建。
-      - ./cache:/cache
-
-      # 媒体库目录：自动整理/重命名/入库需要写权限。
-      - /vol1/1000/Media:/media
-    environment:
-      TZ: Asia/Shanghai
-
-      # PostgreSQL 主数据库。
-      MMTL_DATABASE_TYPE: postgres
-      MMTL_DATABASE_DSN: postgres://mmtl:mmtl@postgres:5432/mmtl?sslmode=disable
-
-      # 旧 SQLite 迁移源：只在从旧版 data/mmtl.db 导入时使用。
-      MMTL_DATABASE_DB_PATH: /data/mmtl.db
-
-      # 路径换算：宿主机路径和容器路径必须一一对应。
-      MMTL_MEDIA_DIR: /vol1/1000/Media
-      MMTL_MEDIA_CONTAINER_DIR: /media
-      MMTL_DOWNLOAD_DIR: /vol1/1000/Downloads
-      MMTL_DOWNLOAD_CONTAINER_DIR: /downloads
+MMTL_DATABASE_DB_PATH: /data/no-sqlite-migration.db
 ```
 
-## 路径映射
+### 必须备份与可重建
 
-路径映射是 Docker 部署里最容易填错的地方。原则是：`volumes` 左边是宿主机真实路径，右边是容器内路径；环境变量里也要保持对应关系。
+| 路径 | 说明 |
+| --- | --- |
+| `./data` | JWT 密钥、运行配置、SQLite 主库或迁移源 |
+| `./postgres` | PostgreSQL 主库（PG 档位） |
+| `./cache` | 海报/转码缓存，可重建 |
+| `./redis` | 热缓存，可重建 |
+| `./opensearch` | 搜索索引，可重建 |
 
-NAS 示例：
-
-```yaml
-volumes:
-  - /vol1/1000/Docker/moviepilot-v2/media:/vol1/1000/Docker/moviepilot-v2/media
-  - /vol1/1000/qBittorrent/downloads:/vol1/1000/qBittorrent/downloads
-environment:
-  MMTL_MEDIA_DIR: /vol1/1000/Docker/moviepilot-v2/media
-  MMTL_MEDIA_CONTAINER_DIR: /vol1/1000/Docker/moviepilot-v2/media
-  MMTL_DOWNLOAD_DIR: /vol1/1000/qBittorrent/downloads
-  MMTL_DOWNLOAD_CONTAINER_DIR: /vol1/1000/qBittorrent/downloads
-```
-
-Windows Docker Desktop 示例：
-
-```yaml
-volumes:
-  - D:/Media:/media
-environment:
-  MMTL_MEDIA_DIR: D:/Media
-  MMTL_MEDIA_CONTAINER_DIR: /media
-```
-
-如果后台添加媒体库时填的是 `/vol1/...`，Compose 里也建议把同一个 `/vol1/...` 挂进容器，避免自动整理和下载入库时路径不可访问。
-
-## 旧 SQLite 迁移
-
-新版推荐 PostgreSQL 作为主数据库。`MMTL_DATABASE_DB_PATH` 不是主库路径，而是旧 SQLite 数据的迁移源。
-
-迁移步骤：
-
-1. 把旧版 `mmtl.db` 放到 `./data/mmtl.db`。
-2. 保持 `MMTL_DATABASE_DB_PATH: /data/mmtl.db`。
-3. 启动一次，确认日志显示迁移完成，网页数据正常。
-4. 备份 `./postgres` 和 `./data`。
-5. 确认不再需要 SQLite 后，把迁移源改成不存在的路径，例如：
-
-```yaml
-environment:
-  # 已完成 SQLite 迁移后，建议改成不存在的路径，避免下次启动重复检查旧库。
-  MMTL_DATABASE_DB_PATH: /data/no-sqlite-migration.db
-```
-
-不要删除 `./postgres`。PostgreSQL 已经是主数据库，删除它会丢失账号、媒体库、订阅、配置和历史数据。
-
-## 日志与 STRM 路径
-
-Compose 模板默认把完整应用日志写入 `./data/logs/app.log`，同时拆分 `./data/logs/warn.log` 和 `./data/logs/error.log`。Docker 自身日志也会保留 10 个 50MB 文件：
-
-```bash
-docker compose logs -f mmtl
-tail -f ./data/logs/app.log
-tail -f ./data/logs/error.log
-```
-
-如果要排查订阅、站点搜索、自动整理或 STRM 生成问题，保持 `MMTL_LOGGING_LEVEL: info`；需要更细日志时临时改成 `debug`，确认后再改回 `info`。
-
-STRM 输出目录请使用容器内可写路径，例如 `/data/strm`，或你已经挂载进容器的媒体目录。旧版本保存过 `/app/data/strm` 的部署会在生成时自动迁移到当前 `MMTL_APP_DATA_DIR`，默认就是 `/data`。
-
-## 更新与备份
-
-更新镜像：
+### 更新镜像
 
 ```bash
 docker compose pull mmtl
 docker compose up -d --no-deps mmtl
 ```
 
-不要执行裸 `docker compose pull` 做日常更新。PostgreSQL / Redis / OpenSearch 是数据与缓存基础组件，compose 已设置为 `pull_policy: missing`，首次部署缺镜像时会拉取，日常更新只建议拉取 `mmtl`。需要升级这些基础组件时，请先备份 `./postgres`，再手动修改镜像版本并单独拉取。
+日常更新只拉 `mmtl` 服务即可，不要随意 `docker compose pull` 升级 PostgreSQL/Redis/OpenSearch 基础镜像。
 
-如果第二档或第三档保留了原始文件名，更新时指定对应完整文件：
+---
 
-```bash
-# 第二档
-docker compose -f docker-compose.standard.yml pull mmtl
-docker compose -f docker-compose.standard.yml up -d --no-deps mmtl
+## 路径映射
 
-# 第三档
-docker compose -f docker-compose.search.yml pull mmtl
-docker compose -f docker-compose.search.yml up -d --no-deps mmtl
+Docker 部署最常见的问题是路径填错。记住：
+
+- `volumes` **左侧**是宿主机真实路径，**右侧**是容器内路径
+- 网页后台添加媒体库时，应填写**容器内**路径（如 `/media/电影`）
+- 若使用自动整理/下载入库，`MMTL_MEDIA_DIR` 与 `MMTL_DOWNLOAD_DIR` 需与挂载一致
+
+NAS 示例：
+
+```yaml
+volumes:
+  - /vol1/1000/Media:/media
+  - /vol1/1000/Downloads:/downloads
+environment:
+  MMTL_MEDIA_DIR: /vol1/1000/Media
+  MMTL_MEDIA_CONTAINER_DIR: /media
+  MMTL_DOWNLOAD_DIR: /vol1/1000/Downloads
+  MMTL_DOWNLOAD_CONTAINER_DIR: /downloads
 ```
 
-必须备份：
+---
 
-```text
-./postgres   PostgreSQL 主数据库
-./data       JWT 密钥、运行配置、旧 SQLite 迁移源
-```
+## 首次使用建议
 
-可重建：
+1. **创建媒体库** → 填写 `/media/...` → 执行扫库
+2. **配置元数据源** → 系统设置中添加 TMDb、Bangumi 等 API
+3. **（可选）连接 qBittorrent** → 下载客户端设置，宿主机可用 `http://host.docker.internal:8085`
+4. **（可选）配置网盘账号** → STRM 管理中添加 OpenList / 115 / WebDAV 等
+5. **第三方播放器** → 以 Emby 服务器添加 `http://服务器IP:18080`，使用 MMTL 账号登录
 
-```text
-./cache      图片缓存、临时文件、转码缓存
-./redis      Redis 热缓存
-./opensearch 搜索索引
-```
+---
 
 ## 常见问题
 
-**启动后还是反复迁移 SQLite？**
+**扫库或入库很慢？**  
+先确认路径映射与数据库档位。网盘扫描还受接口限速与目录规模影响；大库可考虑第二档 Redis 或第三档 OpenSearch。
 
-确认旧数据已经迁移成功后，把 `MMTL_DATABASE_DB_PATH` 改成不存在的路径，例如 `/data/no-sqlite-migration.db`，然后重启容器。
+**qBittorrent 下载后无法整理？**  
+确认下载目录已通过 `volumes` 挂进容器，且 `MMTL_DOWNLOAD_*` 环境变量对应正确。
 
-**扫库或入库速度很慢？**
+**硬链接失败（cross-device link）？**  
+硬链接要求源与目标在同一文件系统/子卷；跨盘、跨 btrfs 子卷或网盘挂载时请改用复制或软链接。
 
-先确认数据库档位和路径映射正确。第一档已经足够大多数场景；第二档 Redis 能缓解频繁刷新造成的数据库压力；第三档主要增强搜索，不会替代媒体扫描本身。网盘扫描还会受网盘接口响应、目录数量和网络质量影响。
+**第三方播放器连不上？**  
+确认地址为 `http://IP:18080`，使用 MMTL 用户账号；反代部署需正确配置外部 URL 与 HTTPS 头。
 
-**qBittorrent 下载完成后无法整理？**
-
-确认 qBittorrent 保存路径已经通过 `volumes` 挂载进 MMTL 容器，并且 `MMTL_DOWNLOAD_DIR` 与 `MMTL_DOWNLOAD_CONTAINER_DIR` 对应正确。
-
-**硬链接目录在 Docker / NAS 上看不到内容？**
-
-硬链接不能直接链接“目录”本身，只能链接目录里的文件。文件管理器执行目录硬链接时会递归创建目标目录结构，并为每个文件创建硬链接。硬链接还要求源文件和目标文件在容器内属于同一个文件系统/子卷；如果下载目录和媒体目录是两个独立 bind mount、不同硬盘、不同 btrfs 子卷或网盘挂载，系统会返回 `invalid cross-device link`，此时请选择“复制”或“软链接”。
-
-**第三方播放器无法连接？**
-
-确认播放器填写的是 `http://服务器IP:18080`，账号密码使用 MMTL 用户账号。反代部署时需要正确设置外部访问地址和 HTTPS 头。
+---
 
 ## 开发构建
 
-本地开发需要 Go、Node.js 和 npm。
+后端通过 `go:embed` 嵌入 `web/dist`，**编译前必须先构建前端**。
 
 ```bash
-# 后端测试
-go test ./...
-
-# 前端依赖与构建
-npm --prefix web install
+npm --prefix web ci
 npm --prefix web run build
 
-# 本地运行后端
-go run ./cmd/server
-
-# 本地运行前端开发服务器
-npm --prefix web run dev
+go test ./...
+go run ./cmd/server          # http://127.0.0.1:8080
+npm --prefix web run dev     # http://127.0.0.1:3000
 ```
 
-前端开发服务器默认访问：
+CI 会在 Release 中提供 Windows / Linux / macOS 的 amd64、arm64 单文件可执行程序。

-## What is it?
+## Overview
 
-MMTL is a self-hosted media center for personal libraries, home NAS, and home-theater users.
+**MMTL** is a self-hosted private media management system for NAS, mini PCs, family sharing, and multi-device playback. This repository is a maintained fork of [MediaStationGo](https://github.com/ShukeBta/MediaStationGo), extended with stronger cloud playback, task queues, remote mounts, and permission controls.
 
-It helps you:
+In practice, MMTL gives you:
 
-- Manage movies, TV shows, anime, variety shows, music, and adult libraries.
-- Create multiple user accounts for family members, friends, or different devices.
-- Scan files and enrich posters, summaries, years, seasons, and episodes.
-- Play in the web UI, or log in with a MMTL account from Emby-protocol apps such as Infuse, VidHub, SenPlayer, and Emby clients.
-- Connect qBittorrent for search, subscriptions, downloads, and post-download organization.
-- Connect OpenList, CloudDrive2, WebDAV, and other storage backends with STRMURL or 302 redirect playback.
-- Run on NAS, mini PCs, VPS, Linux, Windows Docker Desktop, or any Docker-friendly host.
+- A modern **web media library**
+- An **Emby/Jellyfin-compatible protocol gateway** for third-party players
+- A single panel for **local disks, download folders, and cloud storage**
 
-> The project is moving fast. With the default PostgreSQL deployment, back up both `data/` and `postgres/`.
+### Key capabilities
 
----
+| Area | Highlights |
+| --- | --- |
+| **Libraries** | Movies, TV, anime, variety, music, custom libraries; multi-root scanning; poster wall; continue watching |
+| **Metadata** | TMDb, Bangumi, Douban, TheTVDB, Fanart, NFO import, manual matching, scrape queue |
+| **Playback** | Web player, HLS transcoding, danmaku, subtitles, play profiles, history and favourites |
+| **Emby protocol** | Add MMTL in Infuse, SenPlayer, Fileball, etc. and sign in with MMTL accounts |
+| **Remote Emby mounts** | Browse remote Emby libraries inside MMTL without a separate Emby client |
+| **Cloud & STRM** | OpenList, CloudDrive2, 115, WebDAV; STRM sync; upload/download queues; direct or 302 playback |
+| **Downloads & organize** | qBittorrent, site search/subscriptions, post-download organization, file manager |
+| **Users & permissions** | Admin/regular users, expiry, NSFW toggle, play-profile PIN, granular permissions |
+| **Operations** | Unified task queue, recycle bin, storage stats, DLNA casting, settings and logs |
 
-## Key Highlights
+### Tech stack
 
-- **One server, many clients**: deploy MMTL once; you do not need to run a separate Emby server.
-- **Emby-protocol compatibility**: add the server in third-party players as an Emby/Jellyfin-compatible server, then log in with your MMTL username and password.
-- **Multi-user management**: supports admins, regular users, account enable/disable, expiry dates, device management, Bot registration, and redeem codes.
-- **Local + cloud media in one place**: manage local disks, download folders, OpenList, CloudDrive2, WebDAV, and other storage backends from one panel.
-- **Download-to-library workflow**: connect qBittorrent for search, subscriptions, download completion organization, and metadata matching.
-- **NAS-friendly**: simple Docker Compose deployment. The primary database lives under `postgres/`, while runtime secrets and files live under `data/`.
-

-
-## Who is it for?
-
-- **Beginners** who want to edit one `docker-compose.yml` and start the service.
-- **NAS users** who want a low-resource media center for local disks and cloud storage.
-- **PT/download users** who want downloads, organization, metadata, and playback in one panel.
-- **External-player users** who want to log in to Emby-protocol third-party apps with one MMTL account.
-- **Family-sharing users** who want separate user accounts without deploying a separate media server for each person.
-- **Developers** who want to study or extend a Go + React self-hosted media app.

-Docker Compose is the recommended path. Beginners do not need `.env`, bare-metal binaries, or source builds. Use the single-image SQLite template if you want the smallest possible setup.

-## Docker Compose Recommended
+## Deployment tiers
 
-The repository `docker-compose.yml` is the lightweight recommended template: no `.env` required, and by default it only starts `MMTL + PostgreSQL`. This is the best starting point for most NAS users.
+Pick one compose file. Do **not** stack multiple `-f` files.
 
-If you already have an older `./data/mmtl.db`, the first start with the new compose file automatically imports it into PostgreSQL. Keep `./data`; it still stores the JWT secret, runtime data, and the old SQLite migration source.
+| Tier | File | Stack | Best for |
+| --- | --- | --- | --- |
+| Single image | `docker-compose.simple.yml` | MMTL + SQLite | Beginners, single-user, low-resource NAS |
+| Tier 1 | `docker-compose.yml` | MMTL + PostgreSQL | Most home NAS deployments |
+| Tier 2 | `docker-compose.standard.yml` | + Redis | Multi-user, frequent Emby client refreshes |
+| Tier 3 | `docker-compose.search.yml` | + OpenSearch | Very large libraries, advanced full-text search |
 
-### Deployment modes
+### Single-image notes
 
-| Mode | Command | Best for |
-| --- | --- | --- |
-| Single image: SQLite | `docker compose -f docker-compose.simple.yml up -d` | Beginners and single-user setups that want one image only, no PostgreSQL/Redis |
-| Lightweight: PG only | `docker compose up -d` | Most NAS devices, lowest resource use |
-| Standard: PG + Redis | `docker compose -f docker-compose.standard.yml up -d` | Multi-user use and frequent Emby client refreshes |
-| Search enhanced: PG + Redis + OpenSearch | `docker compose -f docker-compose.search.yml up -d` | Huge libraries and future standalone search indexing |
+- Only one MMTL container; database lives in `./data/mmtl.db`
+- Do **not** set `MMTL_DATABASE_DSN` or it switches to PostgreSQL
+- Back up `./data`; `./cache` can be rebuilt
 
-Each compose file is standalone. Do not stack multiple `-f` files together.
+### PostgreSQL notes
 
-The single-image `docker-compose.simple.yml` runs only MMTL with a built-in SQLite database — the simplest starting point. Do not set `MMTL_DATABASE_DSN` there, or it switches back to PostgreSQL. Move up to the PostgreSQL modes for multi-user or high-concurrency use (keep `./data` when you switch). Redis and OpenSearch are enhancement layers, not source databases. Do not enable OpenSearch by default on low-memory NAS devices.
+- Primary DB: `./postgres`; secrets and runtime files: `./data`
+- Existing `./data/mmtl.db` migrates automatically on first start
+- After migration, point `MMTL_DATABASE_DB_PATH` at a non-existent file to disable re-checks
 
-### Database Choice And Disabling SQLite
+### Backup
 
-The current Docker Compose setup uses PostgreSQL by default. SQLite is no longer the primary database in the recommended Docker deployment. The runtime database is controlled by:
-
-```yaml
-environment:
-  MMTL_DATABASE_TYPE: postgres
-  MMTL_DATABASE_DSN: postgres://mmtl:mmtl@postgres:5432/mmtl?sslmode=disable
-```
-
-`MMTL_DATABASE_DB_PATH` is only used as a one-time migration source for old SQLite data:
-
-- Fresh installs: `docker compose up -d` uses PostgreSQL and does not create a new SQLite primary database.
-- Upgrades: if `./data/mmtl.db` exists, the first start with the new compose file imports it into PostgreSQL.
-- Migration fills missing rows by primary key and skips rows that already exist. If it fails partway through, a later start continues the remaining tables.
-- After a successful import, PostgreSQL gets a completion marker in the `settings` table, so the old SQLite file is not imported again.
-- Redis is a hot cache and OpenSearch is a search index; neither is a source database.
-
-Recommended SQLite to PostgreSQL upgrade flow:
-
-```bash
-docker compose pull mmtl
-docker compose up -d --no-deps mmtl
-docker compose logs -f mmtl
-```
-
-After you see `sqlite data migrated to postgres`, or after the web UI shows your users, libraries, and settings correctly, you can stop using the old SQLite file as a migration source.
-
-To make the deployment PostgreSQL-only after migration, keep PostgreSQL selected and point the old SQLite migration path at a non-existent file:
-
-> Only do this after the web UI confirms that users, libraries, settings, and media rows are already present in PostgreSQL.
-
-```yaml
-environment:
-  MMTL_DATABASE_TYPE: postgres
-  MMTL_DATABASE_DSN: postgres://mmtl:mmtl@postgres:5432/mmtl?sslmode=disable
-  MMTL_DATABASE_DB_PATH: /data/disabled-sqlite-migration.db
-```
-
-Then rename or move the old host-side SQLite file as an offline backup:
-
-```bash
-mv data/mmtl.db data/mmtl.sqlite.bak
-```
-
-For bare-metal or custom `config.yaml` deployments, use the same idea:
-
-```yaml
-database:
-  type: postgres
-  dsn: postgres://mmtl:mmtl@127.0.0.1:5432/mmtl?sslmode=disable
-  db_path: ""
-```
-
-Do not delete `./postgres`. After migration, it is the real primary database. Keep `./data` too, because it stores the JWT secret and runtime files.
-
-### Choose an image source
-
-Both image sources are supported. Pick one and put it in `image:`:
-
-| Source | Image | Best for |
-| --- | --- | --- |
-| GitHub Container Registry (GHCR) | `ghcr.io/shukebta/mmtl:latest` | Recommended default, follows repository releases |
-| Docker Hub | `shukbet/mmtl:latest` | Backup source when GHCR is slow or unavailable |
-
-To pin a version, first confirm the tag exists on the repository Packages page. Use this format:
-
-```yaml
-image: ghcr.io/shukebta/mmtl:<version-tag>
-# If GHCR does not have that tag, use Docker Hub as the backup:
-# image: shukbet/mmtl:MMTL-v0.0.72
-```
-
-For the simplest setup, keep GHCR `latest`.
-
-Manual pull examples:
-
-```bash
-# GitHub Container Registry
-docker pull ghcr.io/shukebta/mmtl:latest
-
-# Docker Hub backup
-docker pull shukbet/mmtl:latest
-```
-
-Focus on this part:
-
-```yaml
-volumes:
-  - ./data:/data
-  - ./cache:/cache
-  - ./media:/media
-  - ./downloads:/downloads
-```
-
-Meaning:
-
-| Host path | Container path | Purpose |
-| --- | --- | --- |
-| `./data` | app `/data` | Settings, JWT secret, old SQLite migration source; the primary DB is under `./postgres` |
-| `./cache` | app `/cache` | Cache; safe to clean when needed |
-| `./media` | `/media` | Media libraries; use `/media/...` in the web UI |
-| `./downloads` | `/downloads` | Download directory and organization source |
-| `./postgres` | PostgreSQL `/var/lib/postgresql/data` | New default primary database; back this up |
-| `./redis` | Redis `/data` | Used only in standard mode; hot cache, rebuildable |
-| `./opensearch` | OpenSearch `/usr/share/opensearch/data` | Used only in search-enhanced mode; higher memory use |
-
-If your NAS paths are:
-
-```text
-/vol1/1000/Media
-/vol1/1000/Downloads
-```
-
-change the compose file to:
-
-```yaml
-volumes:
-  - ./data:/data
-  - ./cache:/cache
-  - /vol1/1000/Media:/media
-  - /vol1/1000/Downloads:/downloads
-
-environment:
-  MMTL_MEDIA_DIR: /vol1/1000/Media
-  MMTL_DOWNLOAD_DIR: /vol1/1000/Downloads
-```
-
-Rules:
-
-- The left side of `volumes` is the real path on your host/NAS.
-- The right side is the container path. Keep `/media` and `/downloads` unless you know why you are changing them.
-- In the web UI, create libraries with container paths such as `/media/Movies` or `/media/TV`.
-- Do not write NAS absolute paths as `./vol1/...`; `./` means a folder under the current compose directory.
-- On Windows Docker Desktop, paths like `D:/Media:/media` and `D:/Downloads:/downloads` are fine.
-- If you only scan/play existing media and never organize into the library, you may add `:ro`; if you use organize/rename/ingest, the media mount must stay writable.
-

-
-## First-time Setup
-
-1. **Create a library**
-   - Go to the library page.
-   - Use a container path such as `/media/Movies`.
-   - Start a scan.
-
-2. **Connect qBittorrent**
-   - Go to download client settings.
-   - If qBittorrent runs on the host, try `http://host.docker.internal:8085`.
-
-3. **Configure metadata providers**
-   - Go to system settings / external APIs.
-   - Add TMDb, Bangumi, TheTVDB, Fanart, Douban, or other providers when needed.
-
-4. **Use external players**
-   - Add the server as an Emby/Jellyfin-compatible server.
-   - Server URL: `http://SERVER_IP:18080`.
-   - Use the username and password created in MMTL. No separate Emby server is required.
-   - Admins can create regular users in the web UI or Bot so each person can log in with their own account.
-
-5. **Use cloud playback**
-   - Configure OpenList, CloudDrive2, WebDAV, or another provider in storage settings.
-   - Choose STRMURL or 302 redirect playback in the admin settings.
-   - The enabled option takes priority. If both are disabled, playback falls back to the normal server playback path.

+## Path mapping
+
+The most common Docker mistake is mixing host paths with container paths.
+
+- Left side of `volumes` = real host/NAS path
+- Right side = container path; use `/media/...` in the web UI
+- Keep `MMTL_MEDIA_DIR` / `MMTL_DOWNLOAD_DIR` aligned with mounts when organizing or ingesting downloads
+
+Example:
+
+```yaml
+volumes:
+  - /vol1/1000/Media:/media
+  - /vol1/1000/Downloads:/downloads
+environment:
+  MMTL_MEDIA_DIR: /vol1/1000/Media
+  MMTL_MEDIA_CONTAINER_DIR: /media
+  MMTL_DOWNLOAD_DIR: /vol1/1000/Downloads
+  MMTL_DOWNLOAD_CONTAINER_DIR: /downloads
 ```
 
-The compose templates keep full application logs in `./data/logs/app.log` and split warnings/errors into `warn.log` and `error.log`. Keep `MMTL_LOGGING_LEVEL=info` while diagnosing subscription, site search, organizer, or STRM generation issues; temporarily switch to `debug` only when deeper tracing is needed.
+---
 
-Use a writable container path for STRM output, such as `/data/strm` or a mounted media path. Deployments that previously saved `/app/data/strm` are migrated automatically to the configured `MMTL_APP_DATA_DIR`, which defaults to `/data`.
+## First-time setup
 
-### Backup
-
-For the default PostgreSQL deployment, back up:
-
-```text
-data/
-postgres/
-```
-
-`postgres/` is the primary database and contains users, libraries, settings, and media metadata. `data/` stores the JWT secret, runtime files, and optional old SQLite migration source.
-
-If you enabled the extended modes, these are optional:
-
-```text
-redis/        # hot cache, safe to rebuild
-opensearch/   # search index, rebuildable; backing it up can save reindex time on huge libraries
-```
-
-`cache/` is usually not important. If you explicitly still use `database.type=sqlite`, the primary database remains `data/mmtl.db`.
-
-### Stop
-
-```bash
-docker compose down
-```
+1. Create a library with a container path such as `/media/Movies`, then scan
+2. Add metadata providers (TMDb, Bangumi, etc.) in system settings
+3. Optionally connect qBittorrent (`http://host.docker.internal:8085` when qB runs on the host)
+4. Optionally configure cloud accounts under STRM management
+5. Add the server in Emby-compatible players at `http://SERVER_IP:18080` using MMTL credentials
 
 ---
 
 ## FAQ
 
-### 1. The web page does not open
+**Library scan is slow**  
+Check path mapping and DB tier. Cloud scans also depend on API limits and folder size.
 
-Check the container:
+**qBittorrent downloads are not organized**  
+Ensure the download directory is mounted into the container and env vars match.
 
-```bash
-docker ps
-docker compose logs --tail=100 mmtl
-```
+**Hardlink fails with cross-device link**  
+Hardlinks require the same filesystem/subvolume; use copy or symlink across disks or cloud mounts.
 
-Then open:
-
-```text
-http://SERVER_IP:18080
-```
-
-### 2. The library cannot find files
-
-Most cases are path mistakes.
-
-- Docker maps media to `/media`.
-- In the web UI, use `/media/Movies`, not the original NAS path.
-- Docker maps downloads to `/downloads`; use `/downloads` as the organization source when possible.
-
-### 3. qBittorrent cannot connect
-
-If qBittorrent is on the host, try:
-
-```text
-http://host.docker.internal:8085
-```
-
-If qBittorrent is on another machine, use that machine's LAN IP.
-
-### 4. NAS CPU usage is high
-
-Suggested settings:
-
-- Set `ffprobe.max_concurrent` to `1`.
-- Enable automatic organization, scrape-after-scan, and boot cloud scan only when you really need them.
-- Avoid frequent full-library scans on large libraries. Prefer manual scan or scheduled night sync.
-
-### 5. Should I use `.env`?
-
-Beginners should not. Editing `docker-compose.yml` directly is easier to understand.
-
-`.env` is not required by the provided deployment templates. For the single-image template, edit `docker-compose.simple.yml` directly and only adjust the port, volume paths, and optional hardware device mapping.
+**External player cannot connect**  
+Use `http://IP:18080` and a MMTL user account; reverse proxies need correct external URL and HTTPS headers.

-
-Directory hardlinks are handled by recreating the directory tree and hardlinking
-each contained file. Linux cannot hardlink a directory itself. Hardlinks still
-require the source and target files to be on the same filesystem/subvolume from

 ## Development
 
-Regular users should use Docker. Developers can run:
+The backend embeds `web/dist` via `go:embed`. Build the frontend first.

+npm --prefix web run build
 
-Frontend:
-
-```bash
-cd web
-npm install
-npm run dev
-```
-
-Tests:
-
