 # 推进台账
 
+## R03 / 2026-09-20 / 管理器 GLB 预览亮度修复
+
+- 用户反馈三维机床管理器导入 GLB 后模型太黑。
+- 根因：管理器使用 MeshStandard/Physical PBR 材质，但独立编辑场景没有环境贴图、输出色彩空间和色调映射，高金属度部件几乎只能反射黑色背景。
+- 修复：增加 RoomEnvironment → PMREM 工作室环境、sRGB 输出、ACES Filmic tone mapping、1.45 专用曝光，并增加半球光、环境光、暖主光、冷补光和轮廓光；背景和网格提升为中性工作区灰色。
+- 原 GLB 的 color、metalness、roughness 和纹理不改写；运行模型材质也不受影响。
+- 使用仓库根目录 `/home/mes006/linuxcncWebWASM/MILL700-U_1.glb` 实测：9,418,852 bytes，SHA-256 `bf37130681cc6462412e52744519516e8ade2a3212dd69153c0b1b3e415bcf66`；132 节点、126 网格、最大层级深度 6，110 个高金属度材质。
+- E05 浏览器验收通过，截图显示原有 MILL700 层级模型在管理器中可辨识；报告和截图位于 `coverage/glb-machine-manager/mill700/`。
+- 当前任务：MGR-10 已验证，等待保存和发布。
+
 ## R02 / 2026-09-20 / 部件装配、标定、应用与验收完成
 
 - 新增 `machine-manager.ts`：通用自包含 GLB 部件加载、SHA-256、深复制、八角色和两条机械链校验、AC/BC URDF 生成、组合场景、底座/整机 userData、组合哈希。
