+## 2026-10-21 K96 剧场页服务端分类分页
+
+- 已完整读取 K96 `docs/plans/INBOX.md`。
+- 已从最新 `origin/develop` 创建 ReelShort `feat/k96-theater-feed`。
+- 计划见 FruitServer `docs/plans/2026-10-21-K96-theater-feed.md`。
+- 客户端将新增 TheaterFeedController，并让剧场「全部 / 分类」改用
+  `/app/feed` 服务端游标分页；不改首页 K94/K95 已交付逻辑。
+- 已完成 `CatalogApi.feed` / `CatalogRepository.fetchFeed` 可选 `categoryId`，
+  非空才拼请求参数。
+- 已新增 `TheaterFeedController`：按分类独立缓存，缓存先渲染后静默刷新，
+  10 秒超时、游标追加去重、失败保留旧数据、失败分类切回自动重试。
+- 剧场页「全部」和分类 chips 已改用 theater feed；滚动剩余不足 400px 触发
+  `loadMore`，下拉刷新同时执行 categories 与 theater 刷新，搜索模式保持独立。
+- 已补分类参数、缓存切换、分页去重、hasMore 停止、失败保留、失败重试、
+  分类点击请求和滚动加载 widget 测试。

+- 计划见 FruitServer `docs/plans/2026-10-21-K97-ios-comment-keyboard.md`。
+- Android 保留既有 pinned/channel 策略；iOS 与其他平台改用实时
+  `MediaQuery.viewInsets.bottom`，并补 iOS 键盘避让测试。
+- 已完成 `_isAndroid` 平台分流；Android 的 channel、80ms 防抖和 pinned 逻辑保持不变，
+  iOS/其他平台直接读取实时 viewInsets，超过屏幕 60% 的异常值按 0 处理。
+- 面板已使用 160ms `easeOutCubic` AnimatedPadding；Android 不包裹 SafeArea，
+  iOS/其他平台使用 `SafeArea(top: false)` 处理 home indicator。
+- 已补 iOS insets=300/0 测试，发表按钮在键盘上方；Android pinned 既有用例全部通过。
