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.New logs structured messages with WithName prefix and WithValues key-value pairs
  2. logger.V respects verbosity threshold configured in funcr.Options
  3. logr.NewContext and logr.FromContext store and retrieve logr.Logger across context boundaries
  4. logr.FromSlogHandler adapts standard library slog.Handler to logr.Logger
