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. declare wraps a plugin factory function and forwards api, options, and dirname
  2. declare polyfills api.assertVersion when not present and throws BABEL_VERSION_UNSUPPORTED on version mismatch
  3. declare polyfills api.assertVersion validating integer numbers into range strings and rejecting invalid types
  4. declare preserves pre-existing api.assertVersion without overwriting it
  5. declare defaults undefined or null options to an empty object when invoking the builder
  6. declarePreset aliases declare and wraps preset builder functions with the same API forwarding and polyfills
