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.

Contract
- declare wraps a plugin factory function and passes through api, options, and dirname
- declare polyfills missing targets method returning an empty object
- declare polyfills missing assumption method returning undefined
- declare polyfills missing addExternalDependency method as a callable no-op
- declare polyfills assertVersion which throws BABEL_VERSION_UNSUPPORTED when version is incompatible
- declare preserves pre-existing api methods without overwriting them
- declare defaults options parameter to an empty object when omitted or undefined
- declarePreset functions as an exact alias of declare
