 ## 2026-06-04 Platform Mini Game Session Mapping Model 收口
 
-- 背景：`PlatformEntryFlowShellImpl.tsx` 顶部仍保留拼图 runtime 恢复、跳一跳 pending session、敲木鱼 detail 恢复和敲木鱼 pending session 四段纯 DTO 映射，壳层需要理解 sessionId 优先级、拼图稳定 ID 和 pending draft 默认值。
-- 决策：新增 `src/components/platform-entry/platformMiniGameSessionMappingModel.ts`，收口 `buildPuzzleRuntimeWorkFromSession`、`buildJumpHopPendingSession`、`buildWoodenFishSessionFromWorkDetail` 与 `buildWoodenFishPendingSession`。Module 复用 `normalizeCreationUrlValue` 与 `platformPuzzleIdentityModel`；壳层只保留网络读取、React state、URL 写入和 stage 切换副作用。
-- 影响范围：拼图 runtime URL 恢复、跳一跳生成中作品架打开、敲木鱼生成中作品架打开和敲木鱼草稿 detail 恢复。

 这些规则属于平台壳 session / work 恢复映射，应成为可测试的 **Module**。壳层只负责调用网络、写 React state、写 URL 和切换 stage。

 - 拼图 runtime work 必须保留 `draft.coverImageSrc` 非空门槛，避免启动缺封面的草稿运行态。
 - 拼图 profileId 优先 `publishedProfileId`，否则用 `buildPuzzleResultProfileId(sessionId)`；workId 使用 `buildPuzzleResultWorkId(sessionId)`，缺失时回退 profileId。
 - 拼图 owner 缺省为 `current-user` / `玩家`；`publishReady` 来自 `session.resultPreview?.publishReady`。
+- 方洞 profile 的 `workId` 与 `profileId` 都来自 draft `profileId`；owner 固定为 `current-user`，`sourceSessionId` 来自 sessionId。
+- 方洞 profile 的 `updatedAt` 优先 session `updatedAt`，缺失时使用当前时间；`publicationStatus='draft'`、`playCount=0`、`publishedAt=null`，`publishReady` 来自 draft。
 - 跳一跳 pending sessionId 优先 `sourceSessionId`，缺失时用 `profileId`；素材、路径和 prompt 维持空值兜底。
 - 敲木鱼 detail sessionId 优先级固定为 `work.summary.sourceSessionId > fallbackItem.sourceSessionId > profileId`。
 - 敲木鱼 pending session 保持 `floatingWords=['功德 +1']`、素材 / 音效 / 背景为空的旧默认。
 
 ## Depth / Leverage / Locality
 
-- **Depth**：壳层以四个函数取得恢复用 DTO；ID 优先级和默认 draft 字段藏入 Module Implementation。
+- **Depth**：壳层以少量函数取得恢复用 DTO；ID 优先级、方洞 profile 默认值和 pending draft 字段藏入 Module Implementation。
 - **Leverage**：后续新增生成中作品恢复或修改 sessionId 规则时，先改 Module 与单测，再保持壳层 Adapter 副作用不变。
-- **Locality**：拼图、跳一跳和敲木鱼的恢复映射集中在一个纯测试面，避免在大型壳层顶部继续堆积 DTO 构造。
