+## 2026-07-13 外部生成任务持久化真实执行阶段
+
+- 背景：图片画布任务列表此前把所有 `running` 任务固定映射为“正在生成”，角色生图、图标/UI spritesheet、角色动作和手动去背景进入抠图后仍无法展示“正在处理”；前端按耗时推断阶段会产生新的非正式业务真相。
+- 决策：不新增 DB 表，在既有 `external_generation_job` 与 `external_generation_job_summary` 末尾追加带默认值的可选 `phase`。worker claim 时写 `generating`；角色生图、图标 spritesheet、UI 素材提取在调用 BgFilter 前，角色动作在视频生成返回并开始抽帧/逐帧抠图前，手动去背景在执行开始时，通过 `job_id + worker_id + lease_token` 保护的 procedure 写 `processing`。BFF 将 `running + processing` 映射为“正在处理”，其它 `running`（含旧数据 `phase=None`）映射为“正在生成”；前端只展示后端投影。
+- 影响范围：`external_generation_job`、`external_generation_job_summary`、SpacetimeDB procedure / typed client / bindings、图片画布生成 worker、任务列表 BFF 与相关文档。
+- 验证方式：运行 `npm run spacetime:generate`、`npm run check:spacetime-schema`、外部生成 module/client/api-server 定向测试、`cargo check -p api-server --manifest-path server-rs/Cargo.toml`、`npm run check:encoding` 和 `git diff --check`。

 ## 2026-07-13 角色动作逐帧开启 BgFilter cross-check
 
 - 背景：角色动作逐帧抠图此前为减少额外推理开销固定传 `cross_check=off`，但动作帧同样需要保留发丝、镂空和运动边缘质量。

 - 角色动作逐帧抠图在 api-server 内复用共享 BgFilter HTTP Client；单帧首次失败立即重试 `1` 次，第二次仍失败才进入阿里云/本地降级链。全部 `32 / 40 / 48` 帧按“对应绿幕源图落 OSS → BgFilter/降级 → 透明帧落 OSS”连续加入无序在途流水线，允许响应乱序完成并在最终返回前按 `frameIndex` 恢复顺序；任一帧最终失败时仍排空全部已启动请求，整个动作任务失败退款，不发布缺帧动画。
 - 图片快速编辑面板只保留一个提示词输入框和模型选择，不展示额外参考图或比例 / 尺寸控件；原图 / 原素材作为 `/api/editor/images/edits` 的 `sourceImageSrc` 直接提交，不作为 `referenceImageSrcs`。打开快速编辑时画布必须自动平移缩放，让原素材完整落在可视区上半部分，底部面板固定出现在素材下方且不遮挡内容，竖屏 UI 素材也必须完整展示。快速编辑右侧显示矩形、椭圆、画笔框选工具，但进入时不默认启用；点击工具后显示选中态，再点同一工具取消启用。完成框选后，画布红色细框显示连续序号，提示词可按这些编号填写每个区域怎么改。点击 `修改` 后仍停留在当前快速编辑面板显示修改中，不创建独立 `Quick Edit Generator` 画布占位；生成成功后直接用结果覆盖原图图层，失败时保留当前面板并显示错误。
 - 底部生成类按钮每次点击都必须创建独立的画布生成对象；新建规范、角色形象或图标素材时，只切换当前编辑面板，不得销毁此前尚未生成或已生成后的其它生成对象状态。归档为非当前编辑对象的生成占位仍可拖动、删除和等待异步完成，完成 / 失败回写必须按生成对象 ID 读取最新占位状态，不能使用提交瞬间的旧快照。
-- 画布右上角提供自动隐藏任务侧栏。列表为空且侧栏关闭时只保留图标开关；生成或去背景任务进入时默认打开；用户可手动切换开关状态。
+- 画布右上角提供自动隐藏任务侧栏。列表为空且侧栏关闭时只保留图标开关；生成或去背景任务进入时默认打开；用户可手动切换开关状态。进行中阶段只使用外部生成 BFF 返回的 `phaseDetail`：调用或等待图片 / 视频生成服务时显示“正在生成”，进入 BgFilter、逐帧抠图或独立去背景时显示“正在处理”；前端不得按耗时或任务类型猜测阶段。
 - 画布底部工具栏 / 面板 Dock 提供“画布 Agent”入口。点击后打开右侧独立 Agent 对话面板；桌面端为右侧窄面板，移动端占满可用宽度。该面板与素材侧栏、图层侧栏、右上角任务侧栏互斥，打开 Agent 时必须收起其它侧栏，打开其它侧栏或任务侧栏时也必须收起 Agent。Agent 面板不得在当前画布内容下方追加内联内容，也不默认展示大段功能说明文案。
 - 所有会新建画布生成占位的入口必须先创建 draft，再统一经过 `ImageCanvasGenerationPlacementModel` 计算落点，禁止各入口自行使用当前视口中心裸坐标或原图右侧固定偏移。当前覆盖入口包括 `生成图片`、`生成规范`、`生成角色形象`、`生成图标素材`、`生成视频`、`生成UI设计图` 和 `生成角色动作`。placement 模型的避让对象为所有未隐藏画布图层，以及当前 active / inactive generation dialogs 中仍存在的 placeholder；每个避让矩形按 32px 画布世界坐标间距外扩。候选落点以当前视口世界中心为距离目标，优先选择离视口中心最近且不重叠的占位位置；若中心被占用，会按上下左右和环形候选继续寻找。打开生成面板时必须把避让后的 placeholder 写入 `openCanvasGenerationDialog(...)`，并立即调用 `centerViewportOnPlacement(...)` 居中到新占位中心，保持原 viewport scale 不变；图片快速编辑不属于新建占位入口，提交后覆盖源图。
