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. logr.New initializes a Logger with custom LogSink implementation
  2. LogSink.Info and LogSink.Error receive structured log parameters and error objects
  3. logr.Logger.WithSink and logr.Logger.GetSink swap and inspect the underlying LogSink
  4. logr.Logger.WithCallDepth configures stack frame offset on CallDepthLogSink
  5. logr.Logger.IsZero returns true for uninitialized or discard loggers and false for active sinks
