This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. assert detect-libc ignores process.env overrides (LIBC, npm_config_libc) and strictly evaluates runtime host probes
  2. assert non-Linux platforms return null for familySync and versionSync, not empty strings or OS names
  3. assert isNonGlibcLinuxSync evaluates process.platform === 'linux' and returns false on non-Linux platforms
  4. assert ELF interpreter parsing detects glibc and musl without child process execution
  5. assert versionSync cannot resolve from ELF headers alone and returns null when ldd and diagnostic reports lack version data
  6. assert detect-libc mutates and restores process.report.excludeNetwork when reading process reports
