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. runCreate and runCLI are exported as functions from create-jest
  2. runCreate throws NotFoundPackageJsonError when package.json is missing in target root directory
  3. runCreate throws MalformedPackageJsonError when package.json contains malformed JSON
  4. runCreate initializes JavaScript configuration (jest.config.js) and updates package.json test script
  5. runCreate initializes TypeScript configuration (jest.config.ts) with type import when useTypescript is selected
  6. runCreate initializes ESM configuration (jest.config.mjs) when package.json has type module
  7. runCreate prompts for confirmation and cleanly aborts without modifying files when override is declined
