本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

契约
- assert detect-libc exports GLIBC and MUSL as lowercase string constants 'glibc' and 'musl'
- assert family, version, and isNonGlibcLinux are AsyncFunctions in v2 returning Promises, while familySync, versionSync, and isNonGlibcLinuxSync provide synchronous detection
- assert accessing detectLibc.family as a string property (v1 pattern) fails because typeof family is function, making equality comparisons with GLIBC or MUSL false
- assert evaluating detectLibc.isNonGlibcLinux as a boolean property (v1 pattern) is always truthy in JS, causing glibc Linux systems to mistakenly execute non-glibc code paths
- assert invoking detectLibc.family() without await returns a Promise instance, evaluating to false when compared against string constants and producing '[object Promise]' in template strings
- assert familySync() and versionSync() return null on non-Linux platforms (win32, darwin), rather than empty strings, 'unknown', or throwing, and isNonGlibcLinuxSync() returns false
- assert on Linux platforms, familySync() returns 'glibc', 'musl', or null, with isNonGlibcLinuxSync() returning true for musl and false for glibc
- assert exact parity between synchronous and asynchronous APIs where familySync() === await family(), versionSync() === await version(), and isNonGlibcLinuxSync() === await isNonGlibcLinux()
- assert the legacy v1 property method was removed in v2 and is undefined
- assert internal ELF interpreter parsing extracts PT_INTERP program headers from 64-bit ELF binaries to identify ld-musl- as MUSL and ld-linux- as GLIBC
