 - 处理：compile 成功时把独立物品图片列表序列化写入 `match3d_work_profile.generated_item_assets_json`；`update_match3d_work` / `publish_match3d_work` 保留该字段；API work summary/detail 映射反序列化为 `generatedItemAssets`。前端保持“本次 draft 优先，重进 profile 兜底”的读取顺序。
 - 验证：`cargo test -p spacetime-client match3d --manifest-path server-rs/Cargo.toml`、`cargo test -p api-server match3d --manifest-path server-rs/Cargo.toml`、`npm run test -- src/components/match3d-result/Match3DResultView.test.tsx`。

+- 现象：直接访问 `/works/detail?work=PZ-...`，作品不存在或已下架时会弹出“作品不存在或已下架，将返回首页。”；关闭提示后仍可能停在大白屏。
+- 原因：旧恢复逻辑只覆盖 `/runtime/...`，没有覆盖 `/works/detail`。同时 `selectionStage === 'work-detail'` 且 `selectedPublicWorkDetail === null` 时没有兜底渲染，详情数据为空就只剩空页面。
+- 处理：公开详情失效统一走 `resolveWorkNotFoundRecoveryAction(...)`，覆盖 `/works/detail`、`/gallery/puzzle/detail` 和 `/gallery/visual-novel/detail`；搜索失败和拼图详情 404 分支清理详情/运行态临时状态并回首页；`work-detail` 空数据阶段显示轻量读取态，避免异步间隙白屏。
+- 验证：`npm run test -- src/routing/runtimeNotFoundRecovery.test.ts`、`npm run test -- src/components/rpg-entry/RpgEntryFlowShell.agent.interaction.test.tsx -t "direct missing public work detail alert returns to platform home"`。
