Open-Tech-Foundation / obj-diff
🚀 The Fast, Accurate, JavaScript Objects Diffing & Patching Library.
Open-Tech-Foundation/obj-diff 的健康指数为 100 分中的 64 分，处于「中等」区间。 其得分最高的类别是Vitality（76/100），最低的是Security（51/100）。 最近一次更新在 4 天前。 近期的大部分工作由 1 位贡献者完成。
64
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。
64
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。

已排除计分（无数据或不适用）：间接依赖不含已知公告, 没有长期未处理的公告。 其余权重已重新归一化。 已将 1 个已解析依赖与 OSV 比对。 有 32 项无法评估——没有已解析的版本、生态系统不受支持，或超出所报告的软件包清单。 该仓库未发布任何索引可解析的软件包，因此改为评估仓库依赖图。该图将开发与测试版本固定同交付的依赖混在一起，因此仅对声明的运行时依赖计分；传递性发现仅作为背景信息列出，不计入评分。 未对可达性进行分析。
AI 就绪度
该仓库在多大程度上具备与 AI 编码代理协同开发与维护的条件？这是一枚独立的实验性徽章——权重为 0.0，因此单独呈现，不影响总体健康评分。

依赖安全公告 0
该仓库未发布可被索引解析的包，因此评估的是其自身的依赖图——共 1 个包，其中也包含从不交付的开发与测试版本固定：0 个存在已知公告，0 个为直接依赖。 有 32 个无法评估——没有已解析的版本、生态系统不受支持，或不在所列包清单之内。
没有已知公告影响已评估的依赖。
公告表示依赖图中记录的版本落入某条公告的受影响范围。可达性未经分析，且依赖图包含开发与测试的版本固定——某项发现可能只涉及工具链而非交付的软件。
