+```
+
+说明：
+
+- `android/app/build.gradle.kts` 的 `release` 已配置 `abiFilters`，只保留 `arm64-v8a` 与 `armeabi-v7a`，插件也不会再带入 `x86_64` 原生库。
+- `x86_64` 只用于模拟器，不进入生产包。
+- 不要直接运行 `flutter build apk --release`：默认会编译三套原生库，包体约 57MB。
+- 只有需要进一步压缩单机下载体积时，才考虑 `--split-per-abi` 出分架构包（arm64 约 21MB、armv7 约 19MB），默认不用。

+# Android Studio 调试 HTTP 日志
+
+## 目标
+
+- 仅在调试构建中输出 Dio 请求、响应与异常日志。
+- Android Studio Run 控制台通过 `debugPrint` 展示，logcat 标签保持 `flutter`。
+- Authorization 脱敏，X-Device-Id 保留，二进制响应只显示字节数。
+- 单条请求体或响应体最多 3000 字符。
+
+## 实现步骤
+
+1. 新增 `NetworkLogInterceptor`，支持注入日志回调并保留请求耗时。
+2. 在 Envelope 解包前暂存原始 bytes；日志拦截器追加到拦截链末尾后读取暂存值。
+3. 在 `ApiClient` 注册调试拦截器，`kDebugMode` 与常量开关同时满足时才输出。
+4. 以 fake adapter 补单测，覆盖行格式、脱敏、UTF-8、截断、非 JSON 与二进制。
+5. 运行 `dart analyze lib test` 和 `flutter test`，更新 PROGRESS 留痕。
+
+## 风险与约束
+
+- `ResponseType.bytes` 不能直接 `toString`，响应体统一 `utf8.decode`。
+- Dio 响应拦截器按 FIFO 执行；链尾日志通过 Envelope 暂存的原始 bytes 读取，
+  避免拿到已解包后的 `data`。
+- release/profile 通过 `kDebugMode` 短路，不输出任何 HTTP 日志。
+- 不新增依赖，不提交现有 `pubspec.lock` 改动，不启停服务、不操作真机。

+- 空白简介不创建文本节点、不占高度，不显示 `null/undefined`。
+- 保持封面 80x106 和现有卡片高度，不引入布局溢出。
+
+## 实现
+
+1. `_FavoriteCard` 对 synopsis 做 trim 后条件渲染。
+2. 简介使用 `Flexible` 占据标题、标签与底部统计之间的剩余空间，
+   `maxLines: 2`、`TextOverflow.ellipsis`、次要文案色和字号。
+3. 无简介时继续使用原 Spacer，保持原布局。
+4. widget 测试覆盖有简介、空简介和卡片高度稳定性。

+# 屏幕常亮与前台自动续播
+
+## 目标
+
+- Android 与 iOS 前台保持屏幕常亮，不引入插件或依赖。
+- 用户主动暂停后切后台再回前台，在播放器与票据状态安全时自动续播。
+- 锁定、blocked、票据失败、错误态及浮层遮挡场景不得强制起播。
+
+## 实施步骤
+
+1. Android `MainActivity.onCreate` 添加 `FLAG_KEEP_SCREEN_ON`，保留现有渠道逻辑。
+2. iOS `AppDelegate` 设置 `UIApplication.shared.isIdleTimerDisabled = true`。
+3. 为 `PlaybackSession` 增加无浮层、路线可见且 active 播放器可用的恢复判断。
+4. 调整 `PlayerLogic.onLifecycle`，在现有 PiP 复位和过期票据刷新流程后安全设置播放意图。
+5. 补用户暂停恢复、锁定/票据失败不恢复、后台保存并暂停测试。
+6. 执行 `dart analyze lib test` 与 `flutter test --no-pub`，回填 PROGRESS 后提交合并。
+
+## 风险 / 待确认
+
+- 真机常亮和生命周期行为由 PM 验收，本次不启停服务、不操作设备。
+- PiP 继续沿用现有可见性策略，不额外修改后台播放行为。
+
+## 执行结果
+
+- Android 主 Activity 已添加 `FLAG_KEEP_SCREEN_ON`，未改动 Flutter 渠道与 PiP 逻辑。
+- iOS AppDelegate 已设置 `UIApplication.shared.isIdleTimerDisabled = true`。
+- 用户主动暂停后回前台可安全恢复；过期票据会等待重取完成后再恢复。
+- locked、blocked、票据错误、会话错误、解锁/浮层遮挡和 PiP 场景均不会强制续播。

+# 收藏与观看历史分页 UI
+
+## 目标

+- 观看记录直接使用后端 `dramaTitle/dramaCover/episodeNumber`，缺失时安全兜底。
+
+## 实现步骤
+
+1. 新增通用 `PageResult<T>`，更新 LibraryApi、WatchApi、Repository 与内存替身。
+2. FavoriteController、WatchRecordsController 增加分页状态、请求代次、dramaId 去重。
+3. 页面通过滚动通知触发 `loadMore`，复用下拉刷新并增加通用分页 footer。
+4. 观看卡片优先渲染接口字段，标题为空时用本地化“第 N 集”，封面为空显示占位。
+5. 补 API、Controller 和 widget 测试，运行 analyze 与全量 flutter test。
+
+## 风险与约束
+
+- 刷新期间保持旧列表，成功后原子替换并回到第 1 页；失败保留旧数据。
+- loadMore 与 refresh 通过请求代次隔离，旧响应不得覆盖新列表。

+## 2026-10-22 范围修订
+

+- 观看历史优先使用后端 `dramaTitle/dramaCover/episodeNumber`，只有标题为空时才预取详情。
+- 标题为空且详情也未返回标题时，用本地化“第 N 集”兜底。
+- 有标题的条目点击播放时再按需加载详情，不在列表加载阶段产生 N+1。
+- 使用当前真实后端校验第 1/2 页请求参数、total 与 list；若运行实例仍忽略分页，

+# Seek 后播放位置保持
+
+## 目标
+
+- 拖动进度条后，缓存与观看记录立即使用 seek 完成后的真实位置。
+- 拖动后立即进详情/离开也不会回退到旧进度。
+- 越界位置 clamp，锁定/票据失败不写无效缓存。
+
+## 实施步骤
+
+1. 增加播放位置 clamp 纯函数，缓存写入统一限制在 `0..duration`。
+2. VideoPlayerPort 暴露 seek 方法，PlayerLogic 等待 seek 完成后再读取 controller。
+3. PlayerLogic 统一当前播放快照，监听、缓存和上报共用同一份 position/duration。
+4. 增加 pending seek 屏障，saveCurrentProgress 与离开路径等待 seek 和上报完成。
+5. 补 seek 缓存、越界 clamp、seek 后进详情并返回测试。

+# 播放器 loading 与锁定进度条调整
+
+## 目标
+
+- 播放器票据与 session loading 圈统一为 24×24、线宽 2。
+- 缓冲/加载进度高光改为白色。
+- 未解锁剧集显示静态 inactive 轨道，不进入 loading，不允许拖动 seek。
+
+## 实施步骤
+
+1. 更新 `LoadingProgressTrack` 默认高光颜色，并补颜色断言。
+2. 为 `SeekProgressBar`、`PlayerOverlayData`、`HomeFeedOverlay` 和 `_FeedProgressBar` 增加 locked 状态。
+3. `PlayerPage` 使用 `logic.session.isLocked || episode.locked` 传入两个浮层。
+4. 缩小 `player-ticket-loading` 与 `player-session-loading` 的尺寸和线宽。
+5. 补首页/全屏锁定态、缓冲高光和两个 loading 指示器尺寸测试。
+6. 执行 `dart analyze lib test` 与 `flutter test --no-pub`，回填 PROGRESS 后提交合并。
+
+## 风险 / 待确认
+
+- 锁定态只影响进度条 UI 与手势，不改播放、解锁或接口逻辑。
+- 首页浮层锁定线沿用当前 `Colors.white24` inactive 色，避免改变非锁定轨道样式。
+
+## 执行结果
+
+- 两个播放器 loading 圈均为 24×24、线宽 2、主色不变。
+- loading 高光默认改为白色，普通轨道与首页 white24 轨道颜色未变。

+# 播放器进度拖动画面预览
+
+## 目标
+
+首页 feed 与全屏播放器的进度条在拖动时显示当前时间点的视频画面缩略图、
+当前时间与总时长；松手立即隐藏并提交 seek。缩略图未返回或失败时显示短剧
+封面，不出现空白闪烁或错误文案。
+
+## 性能红线
+
+1. 拖动期间主线程无卡顿；图片解码和原生取帧不得阻塞 UI 线程。
+2. 原生取帧并发数不超过 1。
+3. 预览图最大宽度 240px。
+4. Dart 内存 LRU 缓存不超过 24 帧。
+5. 不新增 pub 依赖。
+6. 不改后端契约。
+
+## 实现
+
+### 缩略图服务
+
+- 新增 `PlaybackThumbnailService`，公开入口按 `episodeId + position` 取
+  `ByteData`，底层通过
+  `MethodChannel('com.stormg.lumadrama/thumbnail')` 调用原生。
+- 时间按 1 秒分桶；同一 bucket 的在途请求合流。
+- 最多 24 帧 LRU；成功和失败结果都做过期控制，避免旧拖动位置覆盖当前预览。
+- 全局单飞；拖动期间只保留最新 bucket，尚未开始的旧请求直接丢弃。
+- 拖动停顿 120ms 后最多预取相邻一个 bucket，松手取消尚未开始的请求。
+- 原生异常、缺失实现和超过 1.5 秒无结果统一返回 `null`。
+
+### 原生取帧
+
+- Android 使用 `MediaMetadataRetriever`，优先本地下载路径，其次签名 URL；
+  `OPTION_CLOSEST_SYNC` 取帧，最大宽 240px，JPEG 质量 70，单线程 Executor，
+  完成后立即 release。
+- iOS 使用 `AVAssetImageGenerator`，应用画面方向，最大尺寸约 240x426，
+  合理时间容差，后台串行队列生成 JPEG。
+- 两端均保证只回调一次；失败或 1.5 秒超时返回 `null`，不向 UI 抛异常。
+
+### UI
+
+- 新增 `ScrubPreviewCard`：宽 120dp、圆角 8、白色 1px 描边，显示
+  `当前时间 / 总时长`；沿拖动点水平跟随并做安全边距 clamp。
+- 首页 `_FeedProgressBar` 与全屏 `SeekProgressBar` 共用该卡片。
+- 封面始终铺在卡片底层；`Image.memory` 仅在帧到达后覆盖，并限制
+  `cacheWidth: 240`。
+- 开始拖动请求当前 bucket，拖动更新只保留最新位置；松手立即隐藏卡片并取消
+  未开始请求。
+- `PlayerPage` 持有页面级服务，dispose 时清空缓存，避免跨页面串集。
+
+## 测试
+
+- 单测：bucket、LRU 淘汰、同 bucket 合流、过期请求丢弃、松手取消、
+  相邻 bucket 防抖、异常/超时回落。
+- Widget：拖动显示预览卡片和时间、松手消失、无缩略图显示封面。
+- 门禁：`dart analyze lib test` 与 `flutter test --no-pub`。
+
+## 非目标
+
+- 不改服务端接口或持久化策略。
+- 不新增第三方依赖。
+- 不启停服务、不操作真机；原生取帧实际效果由 PM 真机验收。

+# 雪碧图 VTT 拖动预览
+
+## 目标
+
+将进度条拖动预览主链路改为服务端雪碧图 + WebVTT 局部裁剪，原生取帧只作为降级：
+
+1. `Episode` 与 `PlayTicket` 解析 `thumbnailsUrl`。
+2. VTT 只拉取/解析一次，内存缓存 10 分钟。
+3. cue 使用起止时间 + 相对 sprite 文件名 + `xywh`，按 position 二分选择。
+4. sprite 图最多缓存 2 张 `ui.Image`，拖动帧只绘制 sourceRect。
+5. 无 VTT、空轴或图片失败时回退现有 `PlaybackThumbnailService`，再回退封面。
+
+## 性能红线
+
+- 拖动帧禁止网络请求与图片解码，只允许 cue 二分查找和 `RawImage.sourceRect` 绘制。
+- VTT 每个 URL 只解析一次；sprite 解码不在 build/build paint 中执行。
+- sprite ui.Image LRU 上限 2 张，页面 dispose 清空。
+- 解码 sprite 最长边超过 2048px 时按比例缩小后常驻。
+- 签名 `thumbnailsUrl` 不写入任何持久化缓存。
+
+## 实施
+
+- 新增 `SpriteThumbnailAxisService`：
+  - Dio 拉取 VTT，403 清缓存后重试一次；
+  - 解析和选 cue 为纯函数，解析失败返回空轴；
+  - 播放器就绪时预取当前 cue 及相邻 sprite；
+  - LRU2 sprite 缓存和 10 分钟 VTT 缓存。
+- `PlayerPage` 持有页面级服务，按当前选中集预取，dispose 时清空。
+- `ScrubPreviewCard` 优先读取已缓存 sprite frame，显示 `RawImage` 裁剪；
+  VTT 未就绪时暂显封面，轴为空/不可用后启动本地取帧，全部失败保留封面。
+- 首页 feed 和全屏播放器都把 `thumbnailsUrl` 传到预览卡片。
+- 不新增 pub 依赖、不改后端契约。
+
+## 测试
+
+- VTT 解析：时间、xywh、多 sprite 文件。
+- cue 选择：命中、越界最近邻。
+- sprite LRU 最多 2 张。
+- 回退状态判定。
+- Widget：sprite 裁剪且不触发本地取帧；无 URL 回退本地；全部失败显示封面。
+- 门禁：`dart analyze lib test`、`flutter test --no-pub`。
+
+## 风险
+
+- 真实网络 VTT/sprite 可访问性和签名过期由 PM 真机验收。
+- 本次不启动服务、不操作真机、不修改 Web/FruitServer。

+### 实现结果
+
+- 新增 `PlaybackThumbnailService`：1 秒 bucket、24 帧 LRU、单飞合流、
+  最新 bucket 优先、停顿 120ms 后最多预取相邻 1 帧、1.5 秒统一回落。
+- 新增 `ScrubPreviewCard`：120dp 宽、圆角 8、白色 1px 描边，显示

+- 计划文档：`docs/plans/2026-10-22-sprite-scrub-preview.md`。
+- 性能红线：拖动帧不发起网络/解码，只做 cue 二分与 sourceRect 绘制；
+  VTT 缓存 10 分钟且只解析一次；sprite ui.Image 最多 2 张；超过 2048px
+  按比例缩放；签名地址不进入持久化缓存。

+### 实现结果
+
+- 新增 `NetworkLogInterceptor`，默认 `debugPrint`，可注入
+  `void Function(String)` 作为单测日志收集器。
+- `enabled` 常量与 `kDebugMode` 同时为真才输出，release/profile 零 HTTP 日志。
+- 请求行包含完整 URL 与 query，同时输出耗时起点、脱敏请求头和格式化请求体。
+- Authorization 仅保留前 8 字符后加 `...`；X-Device-Id 原样输出；
+  其余请求头值统一 `***`。
+- ResponseType.bytes 响应统一 `utf8.decode(..., allowMalformed: true)`，
+  JSON 自动缩进；图片/音视频/字体/PDF/ZIP 等只输出 MIME 与字节数。
+- 请求体和响应体超过 3000 字符时截断并追加 `…(truncated)`。
+- 拦截链为 `AuthHeaderInterceptor → EnvelopeInterceptor → NetworkLogInterceptor`。
+  Envelope 在解包前暂存原始 bytes，末尾日志读取暂存值，因此仍能打印 Envelope
+  处理前的原始响应。
+- 异常路径输出 `[HTTP] ✗ DioException类型 耗时ms URL message`，并继续
+  `handler.next(err)`，不吞异常。

+- 后端依赖：FruitServer `7b69493`（收藏/观看历史 PageResult 与展示字段）
+- 计划：`docs/plans/2026-10-22-library-paging-ui.md`
+
+### 实现
+
+- 新增通用 `PageResult<T>`；`LibraryApi.favorites` 与 `WatchApi.recent`
+  统一请求 `pageIndex/pageSize` 并返回 `PageResult`。
+- 收藏与观看仓储、Controller 增加首屏、刷新、loadMore、total、hasMore、
+  loadingMore 和 loadMoreError；请求代次避免旧刷新/旧分页覆盖新列表。
+- 收藏按 dramaId 去重，观看按 dramaId 去重；空页或 `loaded >= total` 停止请求。
+- 收藏页、观看历史页接入滚动触底加载、下拉刷新、通用分页 footer、总数展示。
+- 观看卡片优先展示分页接口的 `dramaTitle/dramaCover/episodeNumber`；
+  标题为空时显示本地化“第 N 集”，封面缺失时显示占位图标。
+- API 严格解析服务端 PageResult；旧 List 不做客户端全量包装，由后端部署新契约解决。
+- MineLogic 改用分页首屏 `list`，不再调用旧 limit 接口。

+
+### 范围修订：观看标题优先与按需详情
+
+- 分页协议、Repository 与 Controller 分页状态保持不变。
+- `_hydrate` 只对 `dramaTitle` 为空的记录补拉详情；后端已有标题时不再请求详情。
+- 有标题的记录点击播放时才调用 `detailForOpen` 按需加载详情，避免列表阶段 N+1。
+- 标题仍为空时使用本地化“第 N 集”，封面缺失继续显示占位。
+- 移除了旧 List 自动包装为 PageResult 的前端全量兜底，避免掩盖后端契约问题。
+
+真实后端分页取证（仅测试账号写入，不启停服务）：
