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. errors.New creates an error with message
  2. errors.Errorf creates a formatted error
  3. errors.Wrap annotates an error with message and returns nil for a nil error
  4. errors.Wrapf annotates an error with formatted message and returns nil for a nil error
  5. errors.WithMessage adds context message and returns nil for a nil error
  6. errors.WithStack attaches stack information while preserving error message and returns nil for a nil error
  7. errors.Cause recursively unwraps nested errors to retrieve the underlying root cause
