CI / flutter-gates (push) Successful in 2m41s
- home_page Feed segment 改接 CommunityController：骨架屏首载、空态 CTA、 错误横幅重试、下拉刷新（失败保留旧列表 + SnackBar）、触底游标翻页 （失败态只走显式重试，不随滚动风暴自动重打） - PostCard 三形态（单图通栏 4:3 / 多图折叠封面 +N 角标 / 纯文字 6 行）+ PostMediaGrid（列数规则 + ink 80% scrim 精算）+ LikeButton（error 族修订 Colors.red，T3-14 纯展示禁用态，ToggleSync 接线留 T3-15/16）+ FeedSkeleton （呼吸动效尊重减弱动态设置）；降级作者统一「宠友」占位 - SignedNetworkImage：预签名 URL 缓存 key 剥离 X-Amz-* 签名参数， RemoteImage 全仓换用（同图不同签名命中同一缓存条目） - feed 域埋点：feed_viewed 聚合曝光（浏览段开/结算于切 Tab、切分段、 退后台、销毁；≥50% 可见 ≥500ms 段内按帖去重，postId 不上报）+ feed_load_failed（refresh/load_more 双路，会话失效不报） - integration_test/feed_live_test.dart：compose 六容器 Linux 桌面真链路 实测入口（PATBOND_FEED_LIVE=1 门控，默认跳过） - 测试 379 → 421（+42）：四态/尾部三态/翻页不丢不重/降级作者/曝光结算 时机/缓存 key/事件属性全覆盖；analyze 0，format 无 diff Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
