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.

- Handle Ajv async schema validation where invalid data rejects the Promise with Ajv.ValidationError instead of resolving false

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