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
