- community_models：community/media 域 DTO 逐字段照冻结契约手写 JSON 映射 （Post/FeedCard/PostComment/AuthorSummary 降级形态/媒体两步上传凭据等）， 未知枚举抛 FormatException 暴露契约漂移；CursorPage 上移 core 复用 - community_repository：13 路径 19 操作全覆盖；createPost/createComment 必带 Idempotency-Key（每次逻辑提交换新键、刷新重放同键）；点赞/收藏/ 关注走 PUT/DELETE 语义幂等 - community_exceptions：v1.3.0 新增 9 码 + 40902 共码类型化异常映射 - toggle_sync：乐观翻转 + 快照回滚 + 单飞合并最终意图 + 代次守卫， 点赞/收藏共用一套参数化状态机，权威终态对账收敛 - community_controller：Feed 多页缓存 + 首屏四态 + 尾部加载三态 + 游标拼接 + 刷新代次丢弃旧尾页；详情副本与卡片互动状态同源；reset 清态 - app.dart 装配：community 服务分端口直连（:8084），共享 TokenRefresher， 登出同步 reset - 测试 286 → 347（模型映射 / 19 操作线路 / 错误映射 / 竞态序列全覆盖） Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
