+# 模型文件存储与截图封面方案
+
+2026-09-05。用户已确认，本方案已实施；验证结果见[截图封面实施报告](../model-cover-20260905/index.html)。以下保留方案与存储说明。
+
+## 当前文件存储
+
+GLB 经 `/api/tran/v1/content/projects/{id}/assets/upload` 上传到业务服务，完成格式和大小校验后，由业务服务提交至 `http://1.14.103.234:6180/fileapi/upload`。
+
+文件按 `unreal-tran/model/年/月/日/随机ID.glb` 归档。当前 file_svc 部署配置根目录为 `/data/file_svc/files`，未登录远端核查实际磁盘目录。数据库保存 `fsvc://` 文件引用、大小、SHA-256、项目及版本关联；工程 JSON 保存节点、材质和动画。上传成功后删除本机临时文件。
+
+应用内模型读取经过鉴权下载接口。远端 `/f/` 是静态读取地址；本次对两条测试资源的匿名 HEAD 均返回 200，不能将文件本体描述为完全私有。
+
+## 建议的保存封面流程
+
+1. 用户调整到希望保留的相机视角，点击“保存”。
+2. 仅截取 3D 视口，沿用当前相机和模型姿态；临时隐藏选中框、变换控件和网格，截图后立即恢复，不截菜单和属性面板。
+3. 同步复制已渲染画布，缩放并编码 JPEG，建议最长边 640 像素，避免黑图与过大图片。
+4. 通过既有上传接口上传 IMAGE 资产，将上传票据、封面资产与工程放入同一保存队列，保存成功后更新 `coverUri`。
+5. 列表通过受控图片下载解析为 Blob URL 展示，并在页面释放时回收；不把 `fsvc://` 直接当作图片地址，也不为读取缩略图逐条加载完整模型工程。
+
+复用现有 `coverUri` 和 IMAGE 资产类型，无需新增表。固定封面资产编码用于当前版本替换，历史版本引用保留。
+
+建议首次导入完成与手动保存时更新封面；每 30 秒的自动保存仅保存工程，避免持续生成图片。截图或上传失败时继续保存模型内容，保留旧封面并提示封面更新失败。
+
+## 实施时需要补齐的接点
+
+当前编辑器已有视口截图方法，但尚未连接保存流程。模型上传方法写死 MODEL_FILE，需要增加 IMAGE 分支；保存指纹需包含封面变化。列表当前直接使用 `img src=coverUri`，必须同步补图片资产读取映射及鉴权加载，才是完整功能。

+| 实测模型-牛奶卡车-已验证-20260905 | 156 | MODEL-3FA24629D59E4509 | 保留 |

+
+- 记录：保留本次创建的两条模型工程与上传资产，供用户继续测试。
+
+本报告生成过程不修改项目数据。数据保留与清理结果以证据记录为准。
+
+## 问题与待确认项
+
+### 1
+
+- 标题：模型编辑器生成包陈旧，页面实际运行本地模式
+- 状态：已修复并验证
+- impact：新建记录存在，但旧编辑器未读取项目 ID，模型编辑和自动保存未写入内容制作 API。
+- fix：从现有接口版源码重建并暂存编辑器包，增加 build 产物 API 桥接检查。
+
+### 2
+
+- 标题：GLB 上传被文件服务 503 阻断
+- 状态：已修复并验证
+- impact：上传未成功，原工程模型与资产仍保留。
+- requestId：69785305-558a-4a43-99bf-655b4adda274
+- cause：用户级 UT\_FILE\_SERVICE\_BASE\_URL / CONTENT\_BASE\_URL 残留关闭的 127.0.0.1:17180 代理地址
+- fix：恢复到现有配置的远端真实文件服务，保留密钥，仅重启 ut-tran；实际 GLB 上传已返回200
+
+### 3
+
+- 标题：列表“动画”统计口径需确认
+- 状态：待确认，未改功能
+- impact：狐狸实际有 Survey、Walk、Run 3 个原生片段，全部实播通过；列表显示动画1，统计的是1条自编时间轴轨道。
+- suggestion：可将列表文案明确为“动画轨道”，或增加“原生动画3段 / 自编轨道1条”的分项展示，待用户确认后实施。
+
+### 4
+
+- 标题：保存和发布没有刷新项目/版本更新时间
+- 状态：已修复并验证
+- cause：读取实体携带旧 updateTime，updateById 再次写回旧值，数据库自动更新时间未生效。
+- fix：项目、版本两个统一更新方法显式设置当前秒精度时间；无表结构变更。
+- verification：两模型改名生成 V2 草稿并重新发布；API时间、页面时间、最近更新排序和全新浏览器重开均通过。
+
+共 23 张可用截图。完整结构化记录见 evidence.json；模型对象明细未展开。

+# 真实场景与截图封面验证报告
+
+场景保存截图封面及列表按创建时间倒序的功能已实施。本报告记录使用现有模型创建真实场景、保存当前三维视口封面及异常回退的实际验证结果。
+
+2026-09-05 · http://127.0.0.1:6180 · Microsoft Edge · 教员
+
+## 狐狸场景验证更正：撤回原完整通过结论
+
+> **测试结论更正：** 用户指出狐狸没有出现在场景中，经复现确认属实。原报告的 7/7 仅证明引用、保存、封面上传和发布等链路，漏掉了模型真正可见的视觉检查，因此撤回原“完整 E2E 通过”结论。下列修复后证据增加了真实画面和像素差异验证。
+
+### 原结论与漏验
+
+- 原狐狸检查把对象树存在 fox、模型依赖有效以及接口返回成功当作模型已加载可见；旧截图实际没有显示狐狸。两项旧狐狸证据标记为已更正历史记录并移出当前通过率，原文件继续保留用于追溯。
+
+### 根因
+
+- 计算蒙皮模型包围盒前没有同步骨骼矩阵，得到失真的尺寸。
+- 适配场景尺寸时使用 setScalar 覆盖模型已有的归一化缩放；两者叠加将狐狸放大到约 1000 个场景单位，使模型超出视锥。
+
+### 修复内容
+
+- 同步蒙皮矩阵后计算真实包围盒，并保留已有归一化缩放进行相对缩放；新导入模型与已保存模型均使用修正后的尺寸处理。
+- 修复场景 160 的狐狸比例和默认镜头，保存并发布为版本 208；重新生成服务器 JPEG 封面资产 2084。狐狸包围盒约为 0.966 × 2.812 × 6 个场景单位。
+- 同样复核并修正场景 159，保存并发布为版本 209，重新生成服务器 JPEG 封面资产 2087。未修改模型发布版本或数据库表结构。
+
+### 修复后验证
+
+- 真实 UI 从资源库新增狐狸后立即可见，最长边为 6；该新增操作仅在隔离浏览器会话中测试，未保存、无写请求。
+- 两个场景修改、保存、发布后，通过独立新浏览器会话重新打开，使用保存的默认镜头验证；没有未完成模型加载，也没有产生写请求。
+- 关闭模型投影后，对同一画面中模型显示与隐藏的像素进行比较：320 × 180 采样中狐狸改变 4472 像素、牛奶卡车改变 7515 像素，均超过 500 像素阈值。截图中可直接辨认狐狸与卡车。
+- 牛奶卡车默认镜头下部分车身被场景立柱遮挡，但模型确实可见；报告保留这一限制。
+- 最终列表显示狐狸在卡车之前，虽然卡车更新于 19:32、狐狸更新于 19:31，确认排序依据仍为创建时间。
+
+[![修复后独立浏览器重新打开场景 160：狐狸模型清晰可见，并完成像素差异验证。](screenshots/26-fox-visual-regression.png)](screenshots/26-fox-visual-regression.png)
+
+下方标为“历史记录（已更正）”的检查及截图保留用于追溯，不计入当前通过率，也不作为狐狸已经可见的证据。
+
+当前证据项通过 7 / 7；失败 0；其他或未标注 0；已更正历史记录 2；已校验图片文件 22。

+## 数据保留与清理
+
+<pre>
+保留开发环境场景 159（牛奶卡车检验区，PUBLISHED，当前及已发布版本 209，模型 156 / 已发布版本 204）和场景 160（狐狸野外训练区，PUBLISHED，当前及已发布版本 208，模型 157 / 已发布版本 201）。模型原发布版本未修改；模型 157 的当前草稿版本 202 继续保留，未发布或修改。本次无需 DDL 变更。
+</pre>
+
+| 场景 | 模型 / 发布版本 | 最终状态 | 当前版本 |
+|---|---|---|---|
+| 159 · 实测场景-牛奶卡车检验区-20260905 | 156 / 204 | PUBLISHED | 209 |
+| 160 · 实测场景-狐狸野外训练区-20260905 | 157 / 201 | PUBLISHED | 208 |
+
+<pre>
+保留两条真实场景及历史截图用于后续测试和追溯。新增导入狐狸仅在隔离浏览器会话中测试，未保存、无写请求；测试结束后丢弃临时对象。
+</pre>
+
+## 本次问题记录
+
+<pre>

+
+## 后续独立事项
+

+}
+</pre>
+
+## 当前行为与限制
+
+- 手动保存从当前三维视口生成封面；新封面与场景内容、模型引用在同一次工程更新中关联保存。发布前的保存沿用该流程。
+- 截图或封面上传失败时保留旧封面；工程是否保存成功以实际更新请求为准。版本冲突不覆盖其他已保存的内容。
+- 自动恢复及重新打开工程不生成或上传新封面；恢复后的修改需由用户保存后更新封面。
+- 列表按创建时间倒序展示。再次保存不会改变创建时间，也不应因此改变创建时间排序。
+- 牛奶卡车场景保存的默认镜头中，车身部分被场景立柱遮挡；真实网格可见且像素差异验证通过。需要观察完整车身时可旋转镜头。
+
+报告来自 evidence.json，未修改原始证据；所有引用图片已校验存在且非空，点击可查看原图。通过数随证据更新。
