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
- universalify exports fromCallback and fromPromise helper functions
- fromCallback converts callback-based functions to return a promise when called without a callback
- fromCallback rejects the returned promise when the callback yields an error
- fromCallback invokes provided callback function with result when callback is supplied
- fromCallback delivers errors to the provided callback function
- fromPromise converts promise-returning functions to accept node-style callbacks
- fromPromise delivers rejected promise errors to the provided callback function
- fromPromise returns the original promise when invoked without a callback argument
- wrappers preserve the this context of wrapped functions
