sile/libflate 的健康指数为 100 分中的 45 分,处于「存在风险」区间。 其得分最高的类别是Vitality(69/100),最低的是Security(36/100)。 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。

总分 / 100
存在风险

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。

45
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)
活力社区与采用可持续性与治理工程质量安全AI 就绪度

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。

高风险司法辖区政策对加权总体健康应用 75% 的乘数,并对其设置“存在风险”上限 49。
