 生成任务在用户离开生成页后异步完成时，平台壳层必须弹出 `PlatformTaskCompletionDialog`。完成弹窗同样要带来源，例如某个草稿或生成会话，并提供复制按钮复制“来源 + 状态”；如果用户仍停留在生成页并被自动带入结果页或试玩页，生成页 / 结果页本身即为完成反馈，不再额外叠加完成弹窗。
 
+入口配置中的 `open=false` 表示关闭新建创作入口，不表示下架已有草稿、私有作品或公开作品。api-server 的入口熔断只允许拦截新建创作、新建草稿、首次生成入口和 Remix 成草稿等会产生新创作的请求；公开广场列表、公开详情、点赞、已发布作品启动、运行态过程请求、存档 / 浏览记录和已有作品回读不能因为创作入口关闭而返回 `creation_entry_disabled`。平台首页如果遇到旧服务端返回的 `creation_entry_disabled`，只能降级为空列表或隐藏入口，不弹平台级错误弹窗。
+
 `PlatformEntryFlowShellImpl.tsx` 仍是平台入口编排壳，后续维护时应优先把独立 UI 片段、公开作品映射、草稿生成 notice 和运行态状态 helper 拆到 `src/components/platform-entry/PlatformEntryFlowShellImpl/` 或同目录紧邻 helper 文件。拆分只允许改变文件组织，不改变入口配置事实源、默认导出、props、页面阶段、UI 文案或现有交互；其中拼图首访 onboarding 已拆为 `PlatformEntryFlowShellImpl/PuzzleOnboardingView.tsx`。
 
 `platformEntryCreationTypes.ts` 只做前端展示派生，分组时必须把后端 `creationTypes` 里的 `categoryId` / `categoryLabel` 当作可缺失字段处理，空值统一回退到 `recommended` / `热门推荐`，并把历史 `recent` / `最近创作` 归一到推荐分类。`最近创作` 不属于模板分类页签，只能由 7 天内的真实草稿 / 作品架后端数据决定是否展示；展示内容仍然从后端入口配置的模板卡中筛选，不读取或渲染作品标题、作品摘要、草稿阶段文案。
