feat(scenes): 场景管理后端 + 契约 0.5.0/0.7.0/0.4.0(T-WEB-015)
契约先行(三端逐字节一致,已同步 windows/android):
- rest-api -> 0.5.0:新增 GET/POST /api/scenes、GET/PATCH/DELETE /api/scenes/{id}
- data-models -> 0.7.0:新增 §7 Scene 与 7.1 SceneConfig(物理/环境/出生点/相机)
- database -> 0.4.0:新增 scenes 表(config/stats 用 MEDIUMTEXT,迁移可逆)
后端:
- entities/scene.entity.ts + 迁移 AddScenes1789650000000(scenes 表)
- scenes/scene-config.ts:SceneConfig 定义 + 默认值 + **边界收敛**(越界夹紧、
非法枚举回退),保证客户端拿到的参数一定可解释;服务端只存参数不跑物理
- scenes/scenes.service.ts:上传(.glb/.gltf 直接导入;.zip/.pmx/.fbx 转 GLB,
场景不做 humanoid 重绑定、不转 VRM)、列表/详情/更新/软删除、缩略图复用模型
光栅化器、分析复用模型检查器、config 同时接受 JSON 字符串与平铺字段
- scenes/scenes.controller.ts + scenes.module.ts(app.module 注册)
- 审核复用 /api/reviews/:type/:id:TargetType.Scene 接入待审列表与状态流转
- catalog/export 增 scenes[],目录指纹纳入场景变更
- 枚举:TargetType.Scene、AssetKind.Scene / SceneThumbnail
测试:新增 test/scene-config.spec.ts 6 项(默认值/夹紧/枚举回退/出生点上限/颜色/
序列化);规模 19 文件 / 243 项;check-routes 35 条一致。版本 0.6.0。
注:管理端场景页(GLB 预览 + 物理参数可视化)与 Windows 场景选择留待下一轮。
