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. compile a schema containing $async: true
  2. assert valid data resolves the promise with the input data object rather than boolean true
  3. assert invalid data rejects the promise with an Ajv.ValidationError instance
  4. assert validate.errors is null on the compiled function when the promise rejects
  5. assert caught error carries the errors array with keyword and instancePath details
  6. assert wrapping in try/catch handles async validation errors without uncaught promise rejection
