+## 陶泥儿精选重复先查同源同媒体画布副本
+
+- 现象：每次从项目素材中把同一个生成素材拖到画布上，`陶泥儿精选` 都多出一张看起来相同的素材。
+- 原因：素材拖入画布会为图层实例准备 `editor_project_resource`；如果该素材本来带 `sourceResourceId` 指向原始生成资源，而新资源仍按普通 generated 资源公开，精选就会把原件和每次拖拽产生的同源同媒体副本都展示出来。
+- 处理：创建项目资源时保留 `source_resource_id`，并在同项目已有同源同媒体资源时复用已有 resource；确需创建同源同媒体副本时默认 `public_showcase_enabled = false`。公开精选读取和前端精选模型都跳过 `sourceResourceId` 指回同一媒体原件的副本，但不要按图片地址全局去重，避免不同生成步骤共享占位图时被误合并。
+- 验证：`creationShowcaseModel.test.ts` 覆盖同源同媒体副本只展示原件；`ImageCanvasEditorAssetsIntegration.test.tsx` 覆盖拖拽生成素材到画布时继续提交 `sourceResourceId`；`cargo check -p spacetime-module --manifest-path server-rs/Cargo.toml` 确认后端资源复用 / 精选过滤逻辑可编译。

+## 图片画布发布入口 429 也要查 read-url 换签爆发
+
+- 现象：发布域名刚上线或刷新画板后出现短时间 `429`，Nginx access log 中集中为同一 IP / 同一 `editor/canvas?projectid=...` referrer 的 `GET /api/assets/read-url?objectKey=generated-character-drafts/editor/ui-design-assets/.../asset-001.png` 到几十上百个 UI 设计切片；429 行常见 `request_time=0.000`、`upstream_status=-`，error log 写 `limiting requests ... zone "genarrative_api_rps"`。
+- 原因：这类 429 是入口 Nginx `limit_req` 在转发前按 RPS burst 快拒，不是 api-server、SpacetimeDB、worker 或 VectorEngine 的业务 429。UI 设计提取、角色动画帧或大量私有素材恢复会让多个 `ResolvedAssetImage` 同时挂载；如果 `/api/assets/read-url` 只有同 key pending 去重和缓存，没有跨 objectKey 节流，一个页面能在同一秒内发出数百个不同 objectKey 换签请求并打满 `genarrative_api_rps` burst。
+- 处理：不要先放大 Nginx 通用 API 限流；先按 access log 聚合 `read-url` 数量、状态和 referrer，确认是否同一画板页面触发。`assetReadUrlService` 必须统一承接私有 generated 资源换签，并在真实请求前做跨组件轻量节流；画板、素材库、运行态和结果页不得直接绕过该服务调用 `/api/assets/read-url`。
+- 验证：`npm run test -- src/services/assetReadUrlService.test.ts --reporter verbose` 应覆盖大量不同 objectKey 同时换签时首批限量放行、后续按间隔派发；发布现场同类页面刷新时，Nginx `GET /api/assets/read-url` 429 应从 `upstream_status=-` / `genarrative_api_rps` 收敛。

 - 新增 `editor_asset` 表保存账号级素材：`assetId`、`ownerUserId`、`folderId`、名称、图片读取地址、OSS / asset object 引用、图片尺寸、来源类型、prompt、actualPrompt、model、provider、taskId、`assetKind`、`generationInputs`、创建时间和更新时间。素材只跟账号走，不跟 project 走；角色、图标、UI 设计图、视频和音频等生成结果的用户可见输入快照随素材保存。

 - 登录态上传和生成结果必须先落 OSS / asset object，再向 `editor_project_resource` / `editor_asset` 写入轻量 `imageSrc: "/<objectKey>"`、`objectKey` 和 `assetObjectId`；未登录演示态可以在内存里使用 Data URL 预览，但项目、素材库、项目资源和 `editor_canvas.layers_json` 不得写入 `data:image/*`、`data:video/*`、`data:audio/*` 或 `blob:`。旧数据读取时如果已有 `objectKey`，`imageSrc` 归一成 `/<objectKey>`；没有 `objectKey` 的旧 Data URL 需要走修复上传并回写轻量引用。上传到生成面板参考图槽位的图片必须先创建 `editor_project_resource` 行；没有当前工程 ID 时才创建账号级 `editor_asset` 行，随后把对应 `resourceId` 或 `assetId` 写入参考图临时状态，生成请求仍使用临时状态中的图片源或 `objectKey`。
 - 资源表保存资源和素材级元数据；图层位置、层级、分组选中所需 ID 和 groupId 保存在 `editor_canvas` 的布局 JSON。布局 JSON 是混合数组：普通图层按 `layerId/resourceId` 保存，生成器占位和生成器对话框按 `itemType: "generation-dialog"` 保存，不新增单独表。普通图层的新保存不再把 `assetKind/generationInputs` 写入布局 JSON；刷新时优先从 `editor_project_resource` 恢复，旧布局中的同名字段只作为兼容兜底。生成器快照必须包含生成器 ID、模式、提示词、参数、参考图、状态、占位框位置和可选 `generatedLayerId`；宣发素材生成器还必须保存并恢复 `publicationWorkflowId`、`publicationGameInfo` 和 `publicationReferences`，避免刷新后生成卡片字段或参考图丢失。生成器快照中的参考图同样只保存 `resourceId/sourceAssetId` 行引用和展示所需 label，不保存图片 Data URL、signed URL 或 `objectKey`；刷新时用 `editor_project_resource` / `editor_asset` 行恢复临时生成请求所需图片源。生成成功后仍保存该快照，只是渲染时由 `generatedLayerId` 锚定到成品图层而不重复显示灰色占位框。`generationInputs.references` 是用户可见输入快照中的行级索引，只允许保存 `{ title, label, refType, refId }`；生成接口所需的图片 Data URL、signed URL 或 `objectKey` 只存在于提交前的临时参考图状态和请求体字段，不进入资源 / 素材元数据。图层展示尺寸不再作为独立 `Size` 真相保存，刷新与新建图层均按 `Resolution`（`originalWidth/originalHeight`）原分辨率显示。图层组第一版是画布内布局语义，不单独建表。
 - 图片类生成结果除作为 `editor_project_resource` 和画布图层保存外，还要写入账号级 `editor_asset` 素材库；该写入由生成 BFF 在请求携带 `assetFolderId` 时完成。`GENARRATIVE_EXTERNAL_GENERATION_MODE=queue` 下，画布图片、改图、图标素材、UI 素材提取、角色动作、视频、音效和背景音乐生成都先返回 `queueState`，前端轮询 `/api/runtime/external-generation/jobs/{jobId}` 到完成后重新读取项目快照；`inline` 或无项目上下文时才使用响应中的 resource / asset 快照做本地落画布兜底，不再把同一生成结果二次调用素材创建接口。生成请求失败、inline 完成或 queue 任务终态完成 / 失败后，右上角泥点 chip 必须通过 `/profile/dashboard` 回读余额，不做本地乐观扣减。视频结果当前只保存为画布视频资源，不进入图片素材库。
