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

Contract
- errors.New and errors.Errorf create errors with stack trace capture and formatted messages
- errors.Wrap and errors.Wrapf annotate an error with context message and stack trace, returning nil for a nil error
- errors.WithMessage and errors.WithMessagef add context message without altering the cause, returning nil for a nil error
- errors.WithStack attaches stack trace information to an existing error without altering its message
- errors.Cause recursively unwraps nested wrapped errors to retrieve the root underlying cause
- Formatting wrapped errors with %+v outputs the full multi-frame stack trace
