diagnostics:
  - error_pattern: "缺少文件"
    likely_cause: 数据集下载不完整或运行 cwd 不在数据集仓库根目录。
    action: 重新执行 modelscope download --dataset OneScience/DMC，并在下载后的数据集根目录运行验证命令。
  - error_pattern: "SHA256 不一致"
    likely_cause: 文件被截断、损坏或被替换。
    action: 删除损坏文件后重新下载数据集。
  - error_pattern: "energy_xtb"
    likely_cause: extxyz comment 中缺少 MACE DMC 配置要求的能量字段。
    action: 检查数据是否为本仓库 DMC XTB 数据，或同步修改模型配置 energy_key。
  - error_pattern: "forces_xtb"
    likely_cause: extxyz Properties 中缺少 MACE DMC 配置要求的力字段。
    action: 检查数据是否为本仓库 DMC XTB 数据，或同步修改模型配置 forces_key。
