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. package manifest specifies bare-os 3.9.3 with Bare addon configuration and exports for root and package subpaths
  2. declares chdir function signature accepting directory string in TypeScript definitions (index.d.ts)
  3. defines chdir in index.js with argument type validation throwing TypeError on non-string input
  4. implements bare_os_chdir in binding.c delegating directory changes to uv_chdir with libuv error translation
  5. registers chdir symbol in addon native exports table and includes multi-platform prebuild artifacts
