 9. 参考图和 GenerationSpec 按需 GET，切换镜头或设计变化时取消旧查询。GenerationSpec 需要有效的 Direction、VisualState 和形态关联，不生成图片或视频。
 10. 后端当前的 Video Prompt 仍使用镜头描述和参考图，**尚未消费 GenerationSpec**。没有独立 GET Prompt 接口，“读取／生成提示词”仍是 POST；不存在 Prompt 时会调用模型，因此必须确认。`force: false` 复用已有正文；批量响应只有计数和失败列表，不能凭计数构造 Prompt 正文。`generated` 是后端处理成功数，可能包含已存在但状态不为 `prompt_ready` 的复用项。
 
+### 形态图片约定
+
+1. 入口为 `/projects/:projectId/subject-images`；项目导航、拆解主体列表和分镜参考图缺失提示均可进入。图库自动读取后端已生成图片，不需要重新生图才能显示。
+2. 生图使用正式数据库 `SubjectForm.id`。Checkpoint 的领域 `formId` 不是数据库 ID，不能直接调用图片接口。新增查询从项目关联读取正式形态，返回轻量图片元数据，不包含图片的 `rawJson` 或长 Prompt；打开历史弹窗后再读取详细记录。
+3. 单图明确发送 `provider: 'seedream'`，避免后端单图入口默认使用 mock。模型和凭证仅配置在后端，前端不保存 API Key。默认使用后端的 generationPrompt，其次 appearancePrompt；可为本次输入自定义 Prompt，详情显示后端最终实际使用的文本。
+4. 单图宽高同时留空使用后端默认 2K，自定义时必须同时提供正整数，具体尺寸限制仍由模型校验。当前 Seedream Provider 没有使用 negativePrompt，所以页面不提供无效的负向提示词输入。
+5. 单图生成新增历史记录，不删除旧图。无主图时默认勾选“生成成功后设为主图”；已有主图时默认不替换。候选图可以在历史弹窗二次确认后通过 PUT 设为主图，只允许已完成图片。
+6. 批量默认跳过已有主图的形态；勾选“已有主图也新增候选图”发送 `force: true`。后端批量 force 只生成新图，**不会替换已有主图**。批量作用于整个项目，不受类型／文字／缺图筛选影响，也不接收单图的尺寸与自定义 Prompt。
+7. 图库每 6 秒读取一次真实记录，弹窗只在打开时查询该形态图片。数据库存在 pending / generating 时暂停再次生图；网络错误不自动重试有费用的请求。HTTP 200 中的批量部分失败单独展示。
+8. 图片使用持久化后的 `/storage/...` 地址，开发代理已配置。生产环境也必须代理 `/storage/`，不能让 SPA 回退返回 index.html。无效 URL、加载失败、无图和后端生成失败有各自提示；不会自动使用可能过期的 Provider 临时地址。
+9. 设为主图后，回到分镜点击“刷新参考图”读取最新绑定。已有视频提示词不会自动重生成，需要按需覆盖。本页面不会调用 `/production/start` 或实际视频生成。
