 - 现象：拼图生成页已经收到 VectorEngine 图片编辑失败并进入重试态，但用户返回草稿 Tab 后，同一草稿仍显示“生成中”；连续触发多个拼图生成时，失败后还可能只剩一条新增草稿，或者只看到标题为“第1关”的半成品空壳；抓大鹅后台失败时也可能没有任何通知，点击草稿又像重新开始生成。
 - 原因：前端失败 notice 只更新生成页局部状态，pending 作品架条目在失败时被清掉或被非 `generating` 状态误映射为 `ready`；后端作品摘要也可能短暂仍是 `generationStatus=generating`。如果失败消息没有写入 notice，用户离开生成页后不会弹出 `PlatformErrorDialog`；如果打开草稿只看持久化 `generating`，就会绕过失败态恢复。
-- 处理：失败时按 session 保留 pending 作品架条目并标记 `failed`，失败 notice 保存错误消息并触发带来源的 `PlatformErrorDialog`；拼图契约没有 `failed` 枚举，pending 拼图映射为 `idle`，同时用本地失败 notice 覆盖持久化生成中状态和旧的“正在生成”摘要。点击失败草稿应优先用 notice / 后端 session / fallback payload 组装失败生成页，不能重新从 0 秒启动新进度；拼图失败半成品没有有效 `workTitle` 时，作品架标题回退为“拼图草稿”。

+## 生成失败重试不要走新建草稿
+
+- 现象：拼图或抓大鹅生成失败后，在失败页点击“重新生成”，作品架里多出一份新的草稿，原失败草稿仍留在列表里。
+- 原因：重试 handler 曾优先读取缓存的表单 payload 并调用 create-session 路径；失败草稿按 session 留在作品架是正确行为，于是重试动作额外创建了第二份草稿。
+- 处理：只要当前失败页还能恢复到原 `sessionId`，重试就走该 session 的 compile action；只有没有可恢复 session 时，才允许用表单 payload 重新创建草稿。
+- 验证：`npm run test -- src/components/rpg-entry/RpgEntryFlowShell.agent.interaction.test.tsx -t "failed .* draft retry reuses current session"`。

 ## 汪汪声浪草稿试玩不要写正式 run
 
 - 现象：如果草稿结果页试玩和发布后 runtime 共用同一写成绩路径，未发布或未确认资源的草稿试玩会污染正式单局、排行榜和作品统计。
