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. When a gRPC server returns a 5MB payload to a client with default options, the server transmits it without error but the client fails to decode the response with status code ResourceExhausted because the default client-side receive limit is 4MB.
  2. Configuring grpc.WithDefaultCallOptions(grpc.MaxCallSendMsgSize(10*1024*1024)) on the client does not permit receiving 5MB responses and still results in ResourceExhausted.
  3. Configuring grpc.WithDefaultCallOptions(grpc.MaxCallRecvMsgSize(10*1024*1024)) or passing grpc.MaxCallRecvMsgSize to Invoke allows the client to successfully receive the 5MB response.
  4. Sending a 5MB request from a client to a server with default options causes the server to reject the incoming message with status code ResourceExhausted unless the server is configured with grpc.MaxRecvMsgSize.
