+## 草稿作品架打开结果页返回必须回草稿 Tab
+
+- 现象：从草稿 Tab 作品架点击已有草稿进入结果页后，点结果页返回会跳回创作 Tab 模板入口，用户需要重新切回草稿页才能继续找原草稿。
+- 原因：平台壳层只按结果页类型硬编码返回创作入口，没有记录本次创作流是从草稿作品架打开；如果来源标记没有在新建入口时重置，还可能污染下一条创作链路。
+- 处理：从作品架打开任一玩法草稿时标记返回目标为 `draft-shelf`；从创作 Tab 新建、打开模板或退出非草稿来源工作区时重置为 `create`；结果页返回和工作区退出统一消费这个返回目标，并在消费后复位。
+- 验证：`npm run test -- src/components/rpg-entry/RpgEntryFlowShell.agent.interaction.test.tsx -t "puzzle draft result back button returns to draft hub when opened from shelf|agent draft result back button returns to draft hub without syncing result profile"`。

 ## 拼图生成页轮询不要绑展示 phase 或不稳定 setter
 
 - 现象：拼图创作进入生成中页后，`/api/runtime/puzzle/agent/sessions/{sessionId}` 会在 0.3 到 0.5 秒内被反复 GET，看起来像轮询风暴，而不是 3 秒一次的正常刷新。
