Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. grpc.NewServer and bufconn.Listen establish an in-memory gRPC server and dispatch unary RPC calls
  2. UnaryServerInterceptor intercepts request and response and modifies execution flow or context
  3. status.Error and status.Code propagate gRPC status codes and error messages across RPC boundaries
  4. metadata.NewOutgoingContext and metadata.FromIncomingContext transmit custom request metadata headers
  5. grpc.SendHeader transmits response metadata headers back to the client
