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. funcr.NewJSON produces structured log entries formatted as valid JSON
  2. logr.ToSlogHandler adapts logr.Logger into a standard library slog.Handler
  3. logr.Marshaler interface marshals custom types via MarshalLog method
  4. logr.NewContextWithSlogLogger and logr.FromContextAsSlogLogger manage slog.Logger across context boundaries
  5. logr.Discard safely drops all log entries without panicking
