CI / flutter-gates (push) Failing after 20s
- post_detail_page 整页重写：内存副本先渲染 + getPost 拉新、四态 （loading/error+重试/ready/40403 提示后返回 Feed 并刷新）；媒体全量 ——单图原比例（高度钳制 [0.75w,1.33w]）、多图真九宫格（D11 轮播 弃用，本单裁定）+ InteractiveViewer 全屏大图（03 号拍板 E） - 评论区：游标列表触底补页 + 底部输入条创建（幂等键在数据层）+ 仅本人评论渲染删除入口（40301/40404 服务端兜底）；成败埋点对 （durationMs 取输入会话起点、attemptSeq 会话内递增）；CommentTile 升共享组件（@ 回复前缀呈现、降级作者「宠友」占位） - 关注双态钮（tonal ＋关注 / Outlined 已关注 + 取关确认）乐观翻转、 回滚零动画 + SnackBar，user_followed/unfollowed(post_detail) 挂接； 本人帖不渲染 - Feed 接通：整卡与评论钮导航详情（T3-14 占位提示移除）、点赞/收藏 接共享 ToggleSync（详情与卡片同一实例跨页一致）、toggleError 一次性 SnackBar 消费 - 主壳/装配：openPost 按 postId push；create demo 流不再导航已退役的 demo 详情（发布页真实化留 T3-17）；AppState 在 post_detail/Feed 面 消费清零 - compose 冒烟（env 门控默认跳过）：真链路发帖/点赞幂等/收藏/评论/ 删评一轮 + 断网点赞回滚（生产 ApiClient 异常链） Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
