ulikunitz / xz
Pure golang package for reading and writing xz-compressed files
ulikunitz/xz 的健康指数为 100 分中的 59 分，处于「中等」区间。 其得分最高的类别是Engineering Quality（71/100），最低的是Sustainability & Governance（48/100）。 最近一次更新在今天。 近期的大部分工作由 1 位贡献者完成。
59
总分 / 100软件健康指数
指标归入加权类别，统一采用 1–100 量表。总体分先取类别加权平均；当公开证据触发高风险司法辖区政策时，评级会按政策调整，并设置 49（有风险）的上限。AI 就绪度不计入总体分。
59
优秀85-100堪称典范；基本满足所有检验标准
良好70-84健康；仅有轻微不足
中等50-69可接受，但存在明显不足；建议进行审查
存在风险30-49存在重大薄弱环节；采用时应保持审慎
危急1-29问题严重（项目被弃置、仅有单一维护者、缺乏基本工程规范）
评分画像
每条轴代表一个类别。形状比平均值更重要——健康的对象会填满整个图形，而“一峰一谷”式画像意味着某一维度的优势正掩盖另一维度的风险。
