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 bun package.json bin field maps bunx to bin/bunx.exe rather than bin/bun.exe in version 1.2.17
  2. assert require.resolve on bun/package.json succeeds and exposes version 1.2.17
  3. assert package.json bin field is an object defining both bun and bunx CLI targets
  4. assert package.json bin field contains bun entry pointing to bin/bun.exe
  5. assert version 1.2.16 package.json mapped bunx to bin/bun.exe causing bunx alias binary target mismatch
