 进度合并规则：同一集内只前进不后退；换集直接采纳新集；`finished` 只在接近片尾或客户端显式上报时置位。
 这样用户换设备不会看到进度倒退。

+# K100 后台剧集多选上传（分片 + 断点续传 + 批量建集）
+
+> 日期：2026-10-21  
+> 范围：仅 `ReelShortWeb`；不改 FruitServer 后端、不改 ReelShort 客户端、不改接口契约。
+
+## 目标
+
+剧集管理页「批量上传」：多选视频 → 队列分片上传（文件并发 2 / 分片并发 3）→ 单项与字节加权总进度 → 失败隔离/可重试 → localStorage 断点续传 → 上传完成后批量创建分集。
+
+## 步骤
+
+1. 从 `develop` 拉 `feature/episode-batch-upload`。
+2. 新建 `src/views/contentManagement/upload/uploadSessions.ts`：`reel_upload_sessions` 读写/过滤/清理。
+3. 新建 `useUploadQueue.ts`：状态机、文件并发泵、进度加权、pause/retry/remove、complete 写回 assetId/url、挂接 session。
+4. 新建 `UploadTaskRow.vue` / `BatchUploadDialog.vue` / `CreateEpisodesDialog.vue`。
+5. `EpisodeManagementView.vue` 仅加「批量上传」入口，保留原单文件上传。
+6. `zh-CN.ts` / `en.ts` 补齐文案；白名单 mp4/mov/mkv/webm；超限标红不入队；`beforeunload`。
+7. 门禁：`pnpm lint:eslint` + `pnpm build:dev`。
+8. 提交 `feat(admin): 剧集多选分片上传与断点续传` → `--no-ff` 合回 `develop` 并 push。
+
+## 风险 / 待确认
+
+- 续传需用户重新选择本地文件才能匹配；换机器/改名无法自动续传（产品已接受）。

+# K94 首页内容类型 Feed 与无感切换
+
+## 目标
+
+- 首页顶栏「漫剧 / 真人剧 / 推荐」接入既有 `/app/feed`。
+- 每频道独立缓存与分页，切换时先同步展示缓存，再后台静默刷新。
+- 推荐首屏复用 `/app/home/feed` 打平数据，首次进入不额外转圈。
+- 无缓存频道只在黑色内容区显示小转圈，顶栏和底栏保持。
+- 滑动接近末尾自动加载下一页，并在播放器队列中原地追加。
+
+## 分支
+
+- ReelShort：`feat/k94-home-type-feed`，从 `origin/develop` 创建。
+- FruitServer 仅文档留痕，不改功能代码。
+
+## A. 数据层
+
+### A1 FeedPage
+
+新增 `lib/core/data/models/feed_page.dart`：
+
+- `dramas` 使用 `Drama.fromCardJson`。
+- `nextCursor` 兼容数字/字符串，空值或字符串 `"null"` 转为 null。
+- `hasMore` 读取布尔值。
+
+### A2 CatalogApi / Repository
+
+- `CatalogApi.feed({types, cursor, size})` 请求 `/app/feed`。
+- types 为空不传；非空用逗号拼接。
+- cursor 为空不传。
+- 返回结构异常抛 `ApiException(-1, '返回数据格式异常')`。
+- `CatalogRepository` 与 HTTP 实现增加 `fetchFeed`。
+- 所有测试 CatalogRepository 实现同步补齐方法。
+
+## B. 频道控制器
+
+新增：
+
+- `lib/pages/home/home_feed_channel.dart`
+- `lib/core/data/services/home_feed_controller.dart`
+
+`HomeFeedController` 使用每个频道独立状态：
+
+- dramas / cursor / hasMore / loaded / loadingMore / requestSeq
+- 当前 channel，默认 recommend
+- `seedRecommend`：同步写入推荐首屏，不发请求
+- `selectChannel`：同步切频道并 notify；无缓存加载第一页，有缓存静默刷新
+- `refreshCurrent`：失败保留旧列表
+- `loadMore`：cursor 追加，按 drama.id 去重
+- 所有响应必须同时满足“仍为当前频道 + requestSeq 最新”才应用
+- dispose 后停止 notify
+
+## C. 首页接入
+
+### C1 顶栏受控
+
+`HomeFeedHeader`：
+
+- 删除内部 tab 状态、comingSoon 和 SnackBar。
+- 新增 `channel` 与 `onChannelSelected`。
+- 三个 Key 保持不变。
+- refresh 内部 loading 状态保留。
+
+### C2 HomePage
+
+- `_HomePageState` 用 `CatalogController.repository` 创建 HomeFeedController。
+- Catalog 首次有数据时同步 seed recommend，随后在 post-frame 静默刷新 recommend。
+- `_HomeTabs` 使用稳定 Key，删除 `ValueKey(catalog.dramas.first.id)`。
+- 当前频道无数据时，保留 `_HomeTabs` 顶栏/底栏，body 用黑色背景 + 居中
+  `home-feed-channel-loading`。
+- 当前频道有数据时把频道列表传给 PlayerPage。
+- 刷新回调改 `refreshCurrent`；分页回调改 `loadMore`。
+
+### C3 PlayerPage / PlayerLogic
+
+- PlayerPage 增加 `feedChannel` 和 `onLoadMore`。
+- 同频道 feed 列表变化：`updateFeed(..., keepDramaId: currentDramaId)`。
+- channel 变化：`updateFeed(..., keepDramaId: null)`，回到新频道第 1 个。
+- PlayerLogic 保存 factory/coordinator，支持需要换内容时替换 PlaybackSession。
+- 空列表清空 queue/visibleIndices 并停止旧播放。
+- 当前剧仍在新列表且索引不变时，只扩展队列与 episode 列表，不重新 select。
+- PageView 在 `position >= visibleIndices.length - 3` 时调用 onLoadMore。
+
+## D. 测试
+
+新增 `test/core/data/services/home_feed_controller_test.dart`：
+
+- recommendation seed 不发请求
+- 三频道请求 types 分别为 `[] / [ANIME] / [LIVE]`
+- 缓存频道切换不清空并后台刷新
+- loadMore 追加去重、无更多后不再请求
+- 串包只接受最新频道请求
+- refresh 失败保留旧数据
+
+新增顶栏 widget 测试：
+
+- 三个 Key 存在
+- 点击分别回调 anime/live/recommend
+- 当前 channel 决定选中样式
+
+PlayerLogic 测试补充：
+
+- updateFeed 空列表安全
+- 追加列表保持当前剧
+- 切频道列表回到第 1 个
+
+门禁：
+
+- `dart analyze lib test`
+- `flutter test --no-pub`
+- `flutter build apk --debug`
+
+## 风险与控制
+
+1. PlaybackSession 的 episodes 是构造时绑定的列表；分页原地追加时会同步扩展该列表，
+   避免仅换 queue 而 session 仍指向旧列表。
+2. 换频道可能释放并重建播放器 session，这是内容源变化；静默刷新/分页在顺序不变时
+   不重新 select 当前剧，避免视频重启。
+3. 推荐 seed 只保证首帧立即有内容；后台 `/app/feed` 刷新失败时保留 seed。
+4. 首页仍在 `/app/home/feed` 首次加载期间使用既有启动页；频道切换不再触发整页 splash。

+# K95 修复首页频道快速切换卡 Loading
+
+## 目标
+
+- 频道请求完成后始终写回发起请求的频道缓存，不再因用户切走而丢失结果。
+- 每频道明确区分 loaded / loading / in-flight / error，无请求时绝不显示首屏转圈。
+- 首屏和刷新请求增加可注入的 10 秒超时兜底。
+- PlayerLogic 保证连续 feed 更新串行应用，只让最后一次 feed/session 生效。
+
+## 分支
+
+- ReelShort：`fix/k95-feed-switch-loading`，从 `origin/develop` 创建。
+- FruitServer 仅提交计划与 PROGRESS，不改功能代码。
+
+## A. HomeFeedController
+
+每个频道状态增加：
+
+- `List<Drama> dramas`
+- `String? cursor`
+- `bool hasMore`
+- `bool loaded`
+- `bool loading`
+- `bool loadingMore`
+- `String? lastError`
+- `int requestSeq`
+- `Future<bool>? inFlight`
+
+请求规则：
+
+1. 响应成功/失败都写入发起请求的频道状态。
+2. 只有频道仍为当前频道时才 `notifyListeners`。
+3. `requestSeq` 只比较同一频道的新旧请求，不参与跨频道过滤。
+4. 超时时间通过构造参数注入，默认 10 秒。
+5. `loadingFirstPage = !loaded && loading`。
+6. `selectChannel`：
+   - 有缓存：同步显示，未在飞时后台静默刷新
+   - 无缓存且正在飞：等待现有请求，不重复发
+   - 无缓存且有历史错误：自动重试
+   - 从未加载：发起首屏请求
+7. `refreshCurrent` 同样复用 in-flight，防止并发重复刷新。
+8. `loadMore` 失败保留 cursor/hasMore，允许下次继续重试。
+
+## B. PlayerLogic / PlayerPage
+
+### B1 Feed revision
+
+- PlayerLogic 增加 `int feedRevision`。
+- 每次 `updateFeed` 自增 revision，记录最新目标 feed。
+- `_replaceSession` 与 `selectEpisode` 在 await 后校验 revision，过期流程直接返回。
+- 连续 updateFeed 使用串行队列：当前应用结束后再应用最新待处理 feed。
+
+### B2 空队列与频道切换
+
+- 空 feed 不创建新 session，只清空 queue/visibleIndices 并停播。
+- 空 → 非空必须恢复 route visible，并 select 第 0 个。
+- 频道变化通过额外 reset 标志传入 `updateFeed`，即使 drama id 列表相同，
+  也重置到第 1 个并开始播放。
+
+### B3 PlayerPage 更新判定
+
+- `didUpdateWidget` 用 `feedDramas` 的 drama id 列表签名判断内容变化。
+- 同一列表的新 List 实例不重复 updateFeed。
+- 频道变化始终触发 updateFeed，并传 `resetToFirst=true`。
+
+## C. 测试
+
+### HomeFeedController
+
+- A 挂起 → B 成功 → A 成功：A/B loaded 均为 true，切回 A 立即有数据。
+- 同频道旧失败响应不得覆盖新成功响应。
+- 无在飞请求时 `loadingFirstPage=false`。
+- 永不返回的请求在注入超时后结束 loading、写 lastError、loaded=true。
+- 失败频道再次 select 自动重试。
+- loadMore 失败保留原有 hasMore/cursor。
+
+### PlayerLogic
+
+- 连续 5 次 updateFeed，最终 queue/session 对应最后一次列表。
+- 空 → 非空会创建 session 并 select 第 0 个。
+- 频道变化时相同 id 列表也回到第 1 个。
+
+门禁：
+
+- `dart analyze lib test`
+- `flutter test --no-pub`
+- `flutter build apk --debug`
+
+## 风险与控制
+
+1. 跨频道响应写回缓存必须与同频道 seq 校验同时存在；前者解决缓存丢失，后者解决同频道旧请求覆盖新结果。
+2. Player session 替换以 revision 作为唯一有效性判断，避免旧 close/select 回调干扰新 session。
+3. 空队列期间不创建 PlaybackSession；恢复非空时重新创建并起播。
+4. 不改后端、ReelShortWeb、specs；不安装或操作真机。

+- 不切换当前频道、不改变当前列表；仅目标恰为当前频道时 notify。

+  后续再次切回仍执行正常缓存静默刷新。
+- 预取期间用户切换到该频道时等待已有 inFlight，不重复请求。
+
+## B. HomePage / _HomeTabs
+
+### B1 最近可见 feed
+
+`_HomeTabsState` 维护：
+
+- `List<Drama>? _visibleDramas`
+- `HomeFeedChannel? _visibleChannel`
+
+当前频道有数据时更新这两个值，并以当前频道渲染 PlayerPage。

+# 客户端收藏与观看历史分页
+
+## 目标
+
+- `/app/favorites` 改为 `PageResult<AppDramaCardVO>`，默认第 1 页、每页 20，最大 100。
+- `/app/watch/recent` 默认返回 `PageResult<ProgressRespVO>`；请求带 `limit` 时保留一版旧
+  `List<ProgressRespVO>` 响应。
+- 观看历史补充短剧标题、封面、集号和总集数，剧/集均批量查询。
+
+## 实现步骤
+
+1. 收藏关系使用 `selectPage`，按 `created_at DESC, drama_id DESC` 稳定排序；
+   只统计已上线短剧收藏，再按当前页 ID 批量加载短剧。
+2. 观看进度使用 `selectPage`，按 `updated_at DESC, drama_id DESC` 稳定排序。
+3. 当前页的 dramaId / episodeId 去重排序后，分别执行一次 IN 查询并装配展示字段。
+4. Controller 归一化 pageIndex/pageSize；观看历史根据是否传 `limit` 分流新旧响应。
+5. 更新 API 契约 §1.5，补 service/controller 测试。
+
+## 风险与约束
+
+- `limit` 分支仅用于旧客户端兼容，新分页响应与旧 List 响应不能混用。
+- 已下线短剧不计入收藏 total，也不出现在收藏页。
+- 观看历史展示字段找不到对应剧或集时保持 null，不影响历史记录返回。

+
+## 设计
+
+1. `MediaTranscodeOutputService` 统一读取媒体、任务、rendition 与 thumbnail。
+2. rendition 按高度、视频码率、质量倒序，id 正序保证稳定。
+3. thumbnail 优先读取 `thumbnails.vtt`，解析 cue 后分页；无记录返回 `EMPTY`，

+2. `TranscodeService` 增加手动触发：
+   - QUEUED/RUNNING 直接返回现有任务；
+   - FAILED 重置原任务为 QUEUED；
+   - SUCCESS 才创建新任务，紧接着重复触发会复用新 QUEUED 任务。
+3. 新增 `POST /admin/media/{id}/transcode`，校验媒资存在，复用 `episode:upload`。

+2. 转码成功后生成雪碧图与 VTT，登记到 `media_thumbnail`。
+3. 播放接口与详情剧集返回 `thumbnailsUrl`，无产物时为 `null`。

+## 配置模型
+
+- `sys_config.config_key = media.transcode.profile`，值为 JSON。

+
+## 数据与产物
+
+- 新增 `media_thumbnail`，按 `episode_id` 唯一，记录 VTT、雪碧图前缀、采样参数、

+新上传任务 drama_id/episode_id 为 0；旧 worker jar 缺 MediaThumbnail。
+
+## 代码修复
+
+1. 分集保存后按视频 URL 的 objectKey 查找 `media_asset`。

+5. 对 episode_id=0 且源文件不存在的明显测试垃圾标记 CANCELED，不删除。
+
+## 迁移与运行
+

+3. 检查三个 jar 分别含：
+   - admin-api：MediaTranscodeProfile；

+- 当前剧集管理 `EpisodeManagementView.vue` 只有一个 `el-upload` 单文件入口（`http-request="uploadVideo"`），
+  **不支持多选、没有进度条、没有断点续传入口**，`onSession` 也没有落盘。
 
-**后端（FruitServer）**
+## 目标
 
-1. `drama.favorite_count` 从建剧时置 0 之后**没有任何地方自增/自减**：
-   - `FavoriteService.toggle()` 只写/删 `user_favorite`，注释写着「计数走异步聚合」，
-     但仓库里**没有这个聚合任务**，所以收藏数永远是 0
-   - `remove()` / `removeBatch()` 也不维护计数
-   - `LikeService` 是同步维护 `drama.like_count` 的（`DramaService.adjustLikeCount`），收藏应对齐这个做法
-2. 数据库现状（本机 PG `fruitshorts`）：`drama.favorite_count` 全为 0，
-   而 `user_favorite` 实际有记录（剧 1 有 4 条、剧 2 有 2 条、剧 5 有 5 条……）→ 需要回填
-3. 评论数没有单个剧集的计数接口：`GET /app/comments` 是游标翻页，不返回总数
+在剧集管理页提供「批量上传」：一次选多个视频 → 队列分片上传 → 每个文件独立进度 → 失败可重试 →
+刷新/重进页面能续传 → 上传完成后批量创建分集。
 
-**客户端（ReelShort）**
+## A. 上传队列（新建 `src/views/contentManagement/upload/useUploadQueue.ts`）
 
-4. 首页 feed 的收藏回调（`player_view.dart` 约 468 行）是内联实现，**没有调用已有的
-   `_applyFavoriteDelta`**；只有全屏播放页的 `_toggleSave`（`player_view_actions.dart`）调了
-   → 首页收藏后数字不变
-5. 两处 rail 的 `commentCount: drama.commentCount` 是静态值，评论面板关闭后不刷新
-6. 详情页 `DramaStatsCard` 用 `drama.favoriteCount`，`drama_detail_logic.toggleFavorite()`
-   切换后不更新显示
+1. 输入：`File[]` + `dramaId` + 可选 `bizType`
+2. 每项状态机：`waiting → uploading → merging → done / failed / paused`；对外暴露 `items`、`overallPercent`、
+   `start()`、`pause()`、`retry(id)`、`retryAll()`、`remove(id)`、`clear()`
+3. 队列并发：同时最多 2 个文件上传（文件内分片并发沿用 `uploadFile` 的 3）
+4. 进度：文件内 `onProgress` 回调更新单项百分比；总进度 = 各文件字节加权，不是简单平均
+5. 失败隔离：单文件失败不影响其它文件，错误原因记在该项 `error`
+6. 暂停语义（本轮简化，不做 abort）：暂停后不再派发新任务，已在传的分片让其完成
+7. 上传完成后 `completeUploadApi` 拿到 `assetId/url/durationSec` 写回该项
 
-### 任务
+## B. 断点续传（关键）
 
-#### A. FruitServer（后端）
+1. 上传开始（拿到 `uploadId`）即写入 `localStorage`：键 `reel_upload_sessions`，
+   值数组项含 `{ uploadId, fileName, fileSize, lastModified, dramaId, bizType, createdAt }`
+2. 页面进入时读取该键，过滤 `dramaId` 匹配且 24 小时内的会话，弹出提示「发现 N 个未完成上传，是否续传」
+3. 续传前用 `file.name + size + lastModified` 匹配本地重新选择的文件；
+   **文件匹配不上（换机器/改名）则不自动续传，提示后由用户手动重选**
+4. 续传走现有 `resumeUpload(file, uploadId)`；`GET /admin/media/upload/{uploadId}` 返回 404 或已 completed 的会话要从 localStorage 清理
+5. 上传成功、用户移除、用户放弃续传三种情况都要清理对应记录
 
-1. `fruitshorts-module-content/.../service/DramaService.java`
-   - 新增 `adjustFavoriteCount(Long dramaId, int delta)`：SQL 自增，
-     参考现有 `adjustLikeCount`，减号用 `GREATEST(favorite_count - 1, 0)`
-2. `fruitshorts-module-playback/.../service/FavoriteService.java`
-   - 类注释里「计数走异步聚合」改成与 `LikeService` 一致的同步维护说明
-   - `toggle()`：插入关系后 `adjustFavoriteCount(+1)`；`physicalDelete` 返回行数 > 0 时 `-1`
-   - `remove()`：删除成功（返回行数 > 0）时 `-1`
-   - `removeBatch()`：按 dramaId 逐个 `physicalDelete` 并按其返回值 `-1`
-     （保持与前端「取消收藏」一致的物理删除语义，避免逻辑删除挡住再次收藏）
-3. `fruitshorts-app-api/.../controller/AppCommentController.java`
-   - 新增 `GET /app/comments/count?dramaId={id}` → `Result<Long>`，
-     内部 `commentService.countByDrama(dramaId)`（匿名可访问，与列表一致）
-4. `sql/` 下加一次性回填脚本 `sql/backfill_favorite_count.sql`
-   - `UPDATE drama d SET favorite_count = (SELECT count(*) FROM user_favorite f WHERE f.drama_id = d.id AND f.deleted = 0);`
-   - 只放脚本，不要在应用启动时自动执行
-5. 测试
-   - `FavoriteService` 单测：收藏 +1、取消 -1、不会减到负数、removeBatch 多剧集各自扣减
-   - `AppCommentController` 契约测试：`/app/comments/count` 返回数字
+## C. 批量创建分集
 
-#### B. ReelShort（客户端）
+1. 上传完成列表提供「批量创建分集」按钮
+2. 默认值：按文件名自然排序（去扩展名后再比较，`第2集` 排在 `第10集` 之前）；
+   集号 = 该剧当前最大集号 + 1 起顺延；标题取文件名去扩展名；是否免费沿用现有新建默认值
+3. 弹窗内每行可改：集号、标题、是否免费；冲突集号在提交前本地校验并标红
+4. 提交：逐条调用现有 `createEpisodeApi`（`src/api/admin/episode.ts`），
+   逐条显示成功/失败，失败的保留在弹窗内可重试；全部结束后刷新剧集列表
+5. **不新增后端接口**，契约不动
 
-1. `lib/core/data/remote/comment_api.dart`
-   - 新增 `Future<int> count(String dramaId)`，解析 `data`（Long 可能是字符串，用现有 `jsonToInt`）
-2. `lib/core/data/repositories/comment_repository.dart`
-   - 接口与 `HttpCommentRepository` 同步新增 `count`
-3. `lib/pages/player/player_view.dart`
-   - 首页 feed 的 `onSave` 改为复用 `_toggleSave(context, drama)`（内部已有 `_applyFavoriteDelta`）

-   - 新增 `_openComments(context, drama)`：`await openCommentsWithAuth(...)`，
-     结束后 `await commentRepository.count(drama.id)` 并 `setState` 写入 `_commentCounts`；
-     失败静默（保留旧值，不弹错）

-     `_commentCounts[drama.id] ?? drama.commentCount`；`onComments` 都走 `_openComments`
-4. `lib/pages/drama_detail/drama_detail_logic.dart`（收藏数同步）
-   - 记录本地收藏增量，把调整后的收藏数提供给 `DramaStatsCard`
-     （不要改 `Drama` 模型；用 getter 或在 view 层叠加 delta）
-   - 只在切换成功且状态确实变化时 ±1，失败回滚
-5. 测试
-   - `CommentApi.count` 的解析测试（数字 / 字符串两种返回）
-   - 收藏增量逻辑（可抽纯函数或独立小对象）单测：+1、-1、失败不变
