- config: yaml `_base_` 继承 + 深度合并 + 命令行 `--set a.b.c=value` 覆盖，检测循环引用 - registry: 组件按名注册与构建，模型/数据集共用 - device: require_cuda() 守卫，按 CLAUDE.md 约定禁止在无 Nvidia GPU 的设备上训练； 评估与导出走 resolve_device() 允许 CPU - labels: multilabel / multiclass 两种图像级标签形式的共用定义 - logging / seed: 控制台+文件日志、随机种子与 cudnn 确定性 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
