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. testr.NewWithInterface creates a logr.Logger wrapping a custom TestingT implementation
  2. logger.Info logs structured messages and key-value pairs through TestingT
  3. logger.Error logs error details and messages through TestingT
  4. testr.Options Verbosity controls V-level logging enablement and filtering
  5. logger.WithName and logger.WithValues enrich log context prefix and attributes
  6. logger sink implements testr.UnderlierInterface returning the original TestingT instance
