 - 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。

+## 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"`。

 VectorEngine 图片生成 / 编辑在 `request_send` 阶段出现 `timeout` 或 `connect` 错误时，`platform-image` 会对同一请求最多发送 3 次；multipart 图片编辑每次重试都会重新构造 form，避免复用已消费的 body。日志中 `VectorEngine 图片请求发送失败，准备重试` 表示本次失败已进入下一次尝试；最终仍失败时才会写入 `external_api_call_failure` 并返回 504。排查生产失败时应同时统计 retry 前的尝试日志和最终 audit，避免把一次用户请求内的多次发送误判成多个用户请求。
 
+拼图入口直创的 `compile_puzzle_draft` 是长耗时链路：后端会先快速编译草稿并返回 `image_refining` / `generating` 快照，然后在 api-server 后台任务中完成首图、UI 资产、OSS 持久化、作品投影、计费退款和失败态回写。生产排查小程序 `Failed to fetch` 时，若 Nginx access log 里 action POST 是 `499`、`upstream_status=-`，说明客户端或 WebView 先断开；此时不应再把长 POST 是否返回作为生成成败依据，而应继续按实际 `session_id` 查后台任务日志、VectorEngine provider 日志、`external_api_call_failure` 和后续 GET 轮询结果。同一用户可能先轮询旧的 `puzzle-session-*`，随后 POST 新建实际生成 session；必须用 action POST 的 `request_id` 和 `/api/runtime/puzzle/agent/sessions/<session_id>/actions` 路径对齐真实失败请求，避免被前端显示的“来源草稿”误导。
