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. bun@1.3.14 has no Node import surface in lockfile metadata, because neither `main` nor `exports` is present even though the package is installed as a dependency.
  2. assert.equal(lock.version, 3)
  3. assert.equal(bun.version, '1.3.14')
  4. assert.equal(bun.main, undefined)
  5. assert.equal(bun.exports, undefined)
  6. assert.deepStrictEqual(bun.bin, { bun: 'bin/bun.exe', bunx: 'bin/bunx.exe' })
  7. assert.ok(typeof bun.optionalDependencies['@oven/bun-linux-x64'] === 'string')
