CI / flutter-gates (push) Successful in 3m9s
- 新增 PostComposePage（P3 发布页，push 路由 post_form）：正文/类目 （general·help）/九宫格选图（组装 MediaUploader + UploadProgressOverlay， 删格按列表序重发 position）/发布 gating（正文非空 + 在场媒体全 ready） - 发布走「createPost(draft) → PATCH status=published」两步：迁移失败时草稿 已在服务端，UI 明确提示「草稿已保存」；40905 重置幂等键、42203 提示等图、 网络失败同键重放不重复建帖；40902 自动取新 version 重提一次 - 草稿：「存草稿」(manual) 与「取消 → 保留」(on_exit) 两路径 + 进页恢复最新 一条草稿（提示条/清空）；「不保留」软删服务端草稿（post_deleted 触点） - 埋点：新增 post_analytics.dart（发布漏斗五事件 + 媒体三段，键集对齐字典 v3）；MediaUploader 挂接 started/succeeded/failed(含 cancelled) 与 attemptSeq； pageName 枚举补 post_form - PostMediaEditGrid（同文件编辑态）：3 列九宫格 + 虚线「＋」格 + 删除角标 + 进度覆盖层 + 失败整格重试；页级上传汇总条 - create 页只余 AI 生成模拟（M4 原样保留），demo 发布流与 AppState.posts / publishPost / updatePost 及其持久化一并退役；首页 story「发布」与 Feed 空态 CTA 改为 push 真实发布页 - 测试 458 → 502（+44）：发布页 widget 22、发布埋点 11、媒体三段 7、编辑态 九宫格 4、主壳发布闭环 1；另加桌面真链路 integration_test（env 门控） - flutter analyze 0 问题、dart format 无 diff；compose 六容器真链路实测通过 （选图上传 → 发布 → Feed 置顶 → 第二客户端可见） Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
