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. execa(file, args) executes asynchronously and resolves with stdout, exitCode 0, and failed false
  2. execa(file, args, { input }) passes string input to child process stdin
  3. execa(file, args) rejects with error containing exitCode, stderr, and failed true on non-zero exit
  4. execa.sync(file, args) executes synchronously and returns stdout and exitCode
