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. universalify exports fromCallback and fromPromise helper functions
  2. universalify.fromCallback converts a callback-taking function to return a promise when no callback argument is provided
  3. universalify.fromCallback executes with standard error-first callback when a callback argument is provided
  4. universalify.fromCallback rejects promise on callback error
  5. universalify.fromPromise converts a promise-returning function to support standard error-first callback
  6. universalify.fromPromise returns a promise when invoked without a callback argument
  7. universalify.fromPromise delivers rejection to callback as error argument
  8. universalify preserves function name and this context across conversions
