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. Invoke sends a unary RPC request over a ClientConn, invoking configured unary client interceptors and capturing response header and trailer metadata passed via grpc.Header and grpc.Trailer CallOptions.
  2. Invoke immediately returns a gRPC status error with code Canceled when invoked with an already canceled context.
  3. Invoke returns ErrClientConnClosing when invoked on a closed ClientConn.
