+
+- 背景：平台壳内散落创作生成 notice key、pending 作品架占位、失败文案覆盖、拼图稳定 ID、持久化 generating/failed 判断与草稿 Tab 未读点，新增或调整玩法时需要在多处理解 `workId` / `profileId` / `sourceSessionId` / `draftId` 形状。
+- 决策：新增 `src/components/platform-entry/platformDraftGenerationShelfModel.ts` 作为 Draft Generation Shelf Module，Interface 收口 `collectDraftNoticeKeys`、`getGenerationNoticeShelfKeys`、`createPendingDraftShelfState`、各玩法 `buildPending*Works`、`buildCreationWorkShelfRuntimeState`、`collectVisibleDraftNoticeKeys`、`hasUnreadDraftGenerationUpdates`、拼图稳定 ID 与持久化状态判断；`PlatformEntryFlowShellImpl.tsx` 仅作为 React state、网络刷新、路由和弹窗副作用 Adapter。
+- 影响范围：创作中心草稿 Tab 未读点、作品架生成中遮罩、失败草稿摘要、pending 草稿占位、拼图 / 抓大鹅生成恢复和各玩法生成完成通知。

+# 【前端架构】Draft Generation Shelf Model 收口计划
+
+## 背景
+
+`PlatformEntryFlowShellImpl.tsx` 同时承载创作生成状态、草稿 Tab 未读点、pending 作品架占位、失败文案覆盖和跨玩法 notice key。拼图、抓大鹅、方洞、跳一跳、敲木鱼、视觉小说、汪汪声浪、大鱼吃小鱼和宝贝识物各有不同的 `workId` / `profileId` / `sourceSessionId` / `draftId`，这些规则散在平台壳 **Implementation** 内，导致调用方必须理解每种玩法的草稿身份形状。
+
+该 **Interface** 过浅：页面看似只关心“生成中 / 已完成未读 / 失败”，却要知道多 ID 去重、pending 草稿去重、失败摘要、拼图空标题兜底和持久化 generating 覆盖规则。
+
+## 决策
+
+新增 `src/components/platform-entry/platformDraftGenerationShelfModel.ts` 作为 Draft Generation Shelf **Module**。其 **Interface** 收口为：
+
+- `collectDraftNoticeKeys(kind, ids)` / `getGenerationNoticeShelfKeys(item)`：统一把玩法草稿身份映射为 notice key。
+- `createPendingDraftShelfState(...)` 与 `buildPending*Works(...)`：统一把本地 pending 生成状态映射成作品架占位，并避免与后端已有草稿重复。
+- `buildCreationWorkShelfRuntimeState({ item, notices, pendingShelfItems })`：统一输出 `CreationWorkShelfRuntimeState`，处理失败覆盖、拼图空标题 `拼图草稿` 兜底、summary 占位覆盖、生成中遮罩和 ready 未读点。
+- `collectVisibleDraftNoticeKeys(...)` / `hasUnreadDraftGenerationUpdates(...)`：统一草稿 Tab 顶部未读点规则。
+- `buildPuzzleResultWorkId(...)` / `buildPuzzleResultProfileId(...)`、`isPersistedDraftGenerating(...)` / `isPersistedDraftFailed(...)`：把拼图稳定 ID 与持久化状态判断收在同一 **Seam**。
+
+`PlatformEntryFlowShellImpl.tsx` 仍作为 React state 与副作用 **Adapter**：负责写入 `draftGenerationNotices` / `pendingDraftShelfItems`、启动生成、刷新后端列表、打开结果页和弹窗；它不再内联 pending shelf row shape、notice key 汇总和作品架 runtime state 规则。
+
+## 约定
+
+- 新玩法若需进入草稿生成通知，必须在此 **Module** 补 notice key、pending 占位和 visible key 映射，避免在平台壳里新增散落 switch。
+- pending 作品只用于本地生成任务尚未被后端作品架返回时的临时展示；一旦后端已有同一 `sourceSessionId` / `profileId` / `workId`，pending 占位必须让位。
+- 失败 notice 优先级高于持久化 generating，且可通过 pending metadata 提供更具体 summary；否则回退玩法默认失败摘要。
+- 已有封面的拼图草稿即使局部关卡仍在后台生成，也不得被整卡遮罩为不可打开的生成中状态。
+- 本 **Module** 不做网络请求、路由切换、弹窗副作用或 React state 写入，只保留纯 **Implementation**，以提高 **Depth**、**Leverage** 与 **Locality**。
+
+## 验证
+
+- `npm run test -- src/components/platform-entry/platformDraftGenerationShelfModel.test.ts`
+- `npm run test -- src/components/custom-world-home/creationWorkShelf.test.ts -t "generation state|failure notice|failed puzzle"`
+- `npm run test -- src/components/rpg-entry/RpgEntryFlowShell.agent.interaction.test.tsx -t "persisted generating puzzle draft|persisted generating match3d draft|completed baby object match draft"`
+- 针对新 **Module** 与测试执行 ESLint；`PlatformEntryFlowShellImpl.tsx` 保留既有 hook dependency warnings，不在本切片扩大处理。
+- `npm run typecheck`
+- `npm run check:encoding`
